+description: Implement tasks from an OpenSpec change (Experimental)
+category: Workflow
+tags: [workflow, artifacts, experimental]
+---
+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - Context file paths (varies by schema)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read the files listed in `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! You can archive this change with `/opsx:archive`.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Spec sync status (synced / sync skipped / no delta specs)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success (No Delta Specs)**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** No delta specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success With Warnings**
+
+```
+## Archive Complete (with warnings)
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** Sync skipped (user chose to skip)
+
+**Warnings:**
+- Archived with 2 incomplete artifacts
+- Archived with 3 incomplete tasks
+- Delta spec sync was skipped (user chose to skip)
+
+Review the archive if this was not intentional.
+```
+
+**Output On Error (Archive Exists)**
+
+```
+## Archive Failed
+
+**Change:** <change-name>
+**Target:** openspec/changes/archive/YYYY-MM-DD-<name>/
+
+Target archive directory already exists.
+
+**Options:**
+1. Rename the existing archive
+2. Delete the existing archive if it's a duplicate
+3. Wait until a different date to archive
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: "Enter explore mode - think through ideas, investigate problems, clarify requirements"
+category: Workflow
+tags: [workflow, explore, experimental, thinking]
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**
+```

+**Surface risks and unknowns**
+- Identify what could go wrong

+- Suggest spikes or investigations
+
+---
+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   | Insight Type | Where to Capture |
+   |--------------|------------------|
+   | New requirement discovered | `specs/<capability>/spec.md` |
+   | Requirement changed | `specs/<capability>/spec.md` |
+   | Design decision made | `design.md` |
+   | Scope changed | `proposal.md` |
+   | New work identified | `tasks.md` |
+   | Assumption invalidated | Relevant artifact |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally

+
+Propose a new change - create the change and generate all artifacts in one step.
+
+I'll create a change with artifacts:
+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Input**: The argument after `/opsx:propose` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - Context file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read the files listed in `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! Ready to archive this change.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+  version: "1.0"
+  generatedBy: "1.2.0"
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   | Insight Type | Where to Capture |
+   |--------------|------------------|
+   | New requirement discovered | `specs/<capability>/spec.md` |
+   | Requirement changed | `specs/<capability>/spec.md` |
+   | Design decision made | `design.md` |
+   | Scope changed | `proposal.md` |
+   | New work identified | `tasks.md` |
+   | Assumption invalidated | Relevant artifact |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Handling Different Entry Points

+## Ending Discovery
+
+There's no required ending. Discovery might:

+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"

+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change proposal
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+

+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+Propose a new change - create the change and generate all artifacts in one step.
+
+I'll create a change with artifacts:
+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - Context file paths (varies by schema)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read the files listed in `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! You can archive this change with `/opsx:archive`.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Spec sync status (synced / sync skipped / no delta specs)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success (No Delta Specs)**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** No delta specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success With Warnings**
+
+```
+## Archive Complete (with warnings)
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** Sync skipped (user chose to skip)
+
+**Warnings:**
+- Archived with 2 incomplete artifacts
+- Archived with 3 incomplete tasks
+- Delta spec sync was skipped (user chose to skip)
+
+Review the archive if this was not intentional.
+```
+
+**Output On Error (Archive Exists)**
+
+```
+## Archive Failed
+
+**Change:** <change-name>
+**Target:** openspec/changes/archive/YYYY-MM-DD-<name>/
+
+Target archive directory already exists.
+
+**Options:**
+1. Rename the existing archive
+2. Delete the existing archive if it's a duplicate
+3. Wait until a different date to archive
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Enter explore mode - think through ideas, investigate problems, clarify requirements
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   | Insight Type | Where to Capture |
+   |--------------|------------------|
+   | New requirement discovered | `specs/<capability>/spec.md` |
+   | Requirement changed | `specs/<capability>/spec.md` |
+   | Design decision made | `design.md` |
+   | Scope changed | `proposal.md` |
+   | New work identified | `tasks.md` |
+   | Assumption invalidated | Relevant artifact |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+
+**Input**: The argument after `/opsx:propose` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**

+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."

+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash

+   ```
+   Parse the JSON to get:

+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.

+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - Context file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read the files listed in `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! Ready to archive this change.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   | Insight Type | Where to Capture |
+   |--------------|------------------|
+   | New requirement discovered | `specs/<capability>/spec.md` |
+   | Requirement changed | `specs/<capability>/spec.md` |
+   | Design decision made | `design.md` |
+   | Scope changed | `proposal.md` |
+   | New work identified | `tasks.md` |
+   | Assumption invalidated | Relevant artifact |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Handling Different Entry Points

+
+     SQLite. Not even close.
+
+     Unless... is there a sync component?
+```
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change proposal
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+---
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."

+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**

+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+## Context
+
+The OpenCode TUI is built with `@opentui/solid` (a Solid.js-based terminal rendering framework). The UI layer lives in `packages/opencode/src/cli/cmd/tui/` with a plugin-based architecture: the home screen, session view, sidebar, and footer are all composed via named slots (`home_logo`, `home_footer`, `home_prompt`, `session_prompt_right`, etc.) managed by `TuiPluginRuntime`.
+
+This fork will track upstream OpenCode `dev` branch. **Every design decision prioritizes minimal diff to reduce merge conflicts.**
+
+Key branding touchpoints:
+- `component/logo.tsx` — 633-line animated ASCII logo
+- `cli/ui.ts` — CLI wordmark for non-TUI output
+- `routes/home.tsx` — Home screen layout with logo slot, prompt, footer
+- `feature-plugins/home/footer.tsx` — Version, MCP status, directory
+- `feature-plugins/home/tips.tsx` — Tip suggestions
+- `routes/session/footer.tsx` — Session status bar
+- `context/theme/opencode.json` — Default theme
+- `component/dialog-go-upsell.tsx` — OpenCode Go upsell
+- `component/dialog-console-org.tsx` — OpenCode console org picker
+
+## Goals / Non-Goals
+
+**Goals:**
+- Strip OpenCode visual branding from user-facing TUI text and colors
+- Keep structural UI intact (sidebar, Tab agent switch, plugin slots, keybinds)
+- Minimize files changed — prefer additive changes (new theme file, new brand.ts) over rewrites
+- Delete OpenCode commercial features with TODO stubs for future CZ equivalents
+- Maintain easy merge path with upstream `dev` branch
+
+**Non-Goals:**
+- Changing npm package name, config paths (`~/.opencode/`), env vars (`OPENCODE_*`)
+- Rewriting TUI framework, rendering engine, or plugin system
+- Replacing OpenCode commercial features with ClickZetta equivalents (future work)
+- Modifying agent, provider, tool, or session systems
+- Redesigning desktop app or web share UI
+- Removing sidebar, Tab switching, or any structural UI features
+
+## Decisions
+
+### D1: Replace animated logo with static text — minimal rewrite
+
+**Decision**: Replace the body of `logo.tsx`'s `Logo` component with a static "czcode" text render. Keep the file and export name identical so `routes/home.tsx` needs zero changes to its `<Logo />` usage.
+
+**Rationale**: Keeping the same file/export means the diff is contained to one file. Upstream changes to `home.tsx` won't conflict.
+
+**Alternatives considered**:
+- Delete `logo.tsx` entirely → Forces changes in `home.tsx` and any plugin referencing the slot, increases merge conflicts
+
+### D2: New theme file, one-line default change
+
+**Decision**: Add `czcode.json` theme file alongside existing themes. Change the default theme fallback from `"opencode"` to `"czcode"` — a single string change in `theme.tsx`.
+
+**Rationale**: Additive (new file) + one-line change = minimal conflict surface. All existing themes remain untouched.
+
+### D3: Delete commercial dialogs, leave TODO stubs
+
+**Decision**: Delete `dialog-go-upsell.tsx` and `dialog-console-org.tsx`. In `app.tsx` where they were imported/registered, replace with `// TODO(czcode): Add ClickZetta account/subscription dialog here` comments. Do NOT build replacement features.
+
+**Rationale**: Clean removal now, placeholder for future CZ integration. Avoids building features that aren't specced yet.
+
+### D4: Brand constants module
+
+**Decision**: Create `brand.ts` with:
+```ts
+export const Brand = {
+  name: "czcode",
+  display: "CZCode",
+  company: "ClickZetta",
+} as const
+```
+
+Use this only in the ~5 files that have user-visible hardcoded "opencode" strings in the TUI layer. Do NOT rename internal identifiers, paths, or env vars.
+
+**Rationale**: Centralizes the few strings that need changing. Internal code references like `@opencode-ai/plugin` stay untouched — they're not user-visible and changing them would create massive merge conflicts.
+
+### D5: Home screen — text-only changes
+
+**Decision**: In `routes/home.tsx`, only change:
+1. Placeholder text arrays (3 strings)
+2. Keep all layout, slots, and structural code identical
+
+In `feature-plugins/home/footer.tsx`, only change the version display text.
+In `feature-plugins/home/tips.tsx`, update tip content strings.
+
+**Rationale**: Minimal line changes = easy merge. The layout is already prompt-centric.
+
+### D6: Session chrome — visual-only, no structural changes
+
+**Decision**: Keep sidebar (files/todo/MCP/LSP), Tab agent switching, and all session UI structure. Only change:
+- Remove "Get started /connect" text in `session/footer.tsx`
+- Replace any user-visible "opencode" strings with brand constants
+- Colors come from theme automatically — no per-component color changes needed
+
+**Rationale**: The session chrome is functional, not branded. Theme change handles colors globally. Structural preservation means zero merge conflicts in session code.
+
+## Risks / Trade-offs
+
+- **[Upstream merge — LOW]** → With this minimal approach, conflicts are limited to: `logo.tsx` (full rewrite), `app.tsx` (import removals), and one line in `theme.tsx`. All other changes are additive or string-only.
+- **[Incomplete branding]** → Some deep error messages or generated text may still say "opencode". Acceptable for v1; the final audit task catches user-visible ones.
+- **[Commercial feature gap]** → Deleting Go/console dialogs without replacement means czcode has no account system. TODO stubs mark where to add CZ equivalents later.
+- **[Theme contrast]** → New czcode theme needs testing across terminals. Mitigation: test on iTerm2, Terminal.app, Alacritty.

+## Why
+
+OpenCode is an open-source AI coding agent with a rich TUI. We are forking it to create **czcode** — a ClickZetta Lakehouse-branded AI coding assistant. The current UI carries OpenCode's visual identity (animated logo, "opencode" naming, Go/Zen subscription upsells). To ship czcode as a ClickZetta product we need to strip the OpenCode visual brand and apply ClickZetta design language, while keeping the fork easy to merge with upstream.
+
+## What Changes
+
+- Replace the OpenCode animated ASCII logo with a static czcode text banner
+- Replace user-facing "opencode" / "OpenCode" text with "czcode" / "CZCode" **in the TUI layer only**
+- Remove the ornate logo animation system (`logo.tsx`) and replace with a minimal static brand mark
+- Strip OpenCode commercial dialogs (Go upsell, console org) — **delete only, no replacement; leave TODO comments for future CZ equivalents**
+- Add a new `czcode.json` default theme with ClickZetta brand colors
+- Update home screen placeholders and tips to reference ClickZetta Lakehouse
+- Update CLI wordmark in `cli/ui.ts`
+- **Preserve** all structural UI features: sidebar (files/todo/MCP/LSP), Tab agent switching, keybinds, plugin slots — only strip OpenCode visual branding from them
+
+### Explicitly NOT changed (merge-friendly)
+- npm package name (`opencode-ai`), config file paths (`~/.opencode/`), env vars (`OPENCODE_*`)
+- TUI config schema field names
+- Plugin slot names and contracts
+- Desktop app, web share UI, server/backend code
+- Agent system, tools, providers, session management
+- Share functionality (kept as-is for now)
+
+## Capabilities
+
+### New Capabilities
+- `czcode-branding`: User-facing text replacement (logo, wordmark, error messages, startup text) — TUI layer only, no path/env changes
+- `czcode-theme`: New default theme file with ClickZetta colors; existing themes remain available
+- `czcode-home-screen`: Home screen visual rebrand — static logo, CZ placeholders/tips, CZ footer text
+- `czcode-session-chrome`: Visual-only rebrand of session footer, sidebar headers, permission prompts — no structural changes
+- `czcode-config`: Default theme value change; startup loading text; version display prefix
+
+### Modified Capabilities
+
+## Impact
+
+- **TUI component layer** (`packages/opencode/src/cli/cmd/tui/`): Targeted text/color changes in `component/logo.tsx`, `routes/home.tsx`, `feature-plugins/home/`, `routes/session/footer.tsx`
+- **Theme system** (`context/theme/`): One new JSON file, one default-value change
+- **CLI entry** (`cli/ui.ts`): Wordmark replacement
+- **Deleted files**: `dialog-go-upsell.tsx`, `dialog-console-org.tsx` (with TODO stubs)
+- **No backend/server/path/env changes** — minimizes merge conflicts with upstream

+## ADDED Requirements
+
+### Requirement: User-facing TUI text SHALL use czcode branding
+The TUI SHALL display "czcode" or "CZCode" wherever "opencode" or "OpenCode" previously appeared in user-visible text within the TUI layer. A centralized `brand.ts` module SHALL export brand constants. Internal identifiers, import paths, package names, config file paths, and environment variables SHALL NOT be changed.
+
+#### Scenario: TUI displays czcode branding
+- **WHEN** the user interacts with the TUI (home screen, session, dialogs)
+- **THEN** all user-visible text references the product as "czcode" or "CZCode"
+
+#### Scenario: Internal paths are unchanged
+- **WHEN** the system resolves config paths, env vars, or package imports
+- **THEN** they continue to use "opencode" naming (e.g., `~/.opencode/`, `OPENCODE_*`, `@opencode-ai/*`)
+
+### Requirement: CLI wordmark SHALL display czcode identity
+The non-TUI CLI output (used when stdout is not a TTY) SHALL render a "czcode" wordmark instead of the OpenCode wordmark in `cli/ui.ts`.
+
+#### Scenario: Piped output shows czcode wordmark
+- **WHEN** the CLI output is piped (not a TTY)
+- **THEN** the wordmark text reads "czcode" instead of "opencode"
+
+### Requirement: OpenCode commercial features SHALL be deleted with TODO stubs
+The `dialog-go-upsell.tsx` and `dialog-console-org.tsx` components SHALL be deleted. Where they were imported/registered, TODO comments SHALL be left indicating future ClickZetta equivalents. No replacement features SHALL be built.
+
+#### Scenario: Commercial dialogs are removed
+- **WHEN** the user interacts with the TUI in any workflow
+- **THEN** no OpenCode Go/Zen upsell or console org picker dialogs appear
+
+#### Scenario: TODO stubs exist for future replacement
+- **WHEN** a developer reads `app.tsx` where commercial dialogs were registered
+- **THEN** TODO comments indicate where to add ClickZetta account/subscription features

+## ADDED Requirements
+
+### Requirement: Home screen SHALL display a static czcode brand mark
+The `Logo` component in `logo.tsx` SHALL be replaced with a static "czcode" text banner. The file and export name SHALL remain identical to minimize upstream merge conflicts. No animation, glow, shimmer, or interactive effects SHALL execute.
+
+#### Scenario: Home screen renders static brand
+- **WHEN** the user is on the home screen
+- **THEN** a static "czcode" text banner is displayed above the prompt
+
+#### Scenario: Logo file and export are preserved
+- **WHEN** `routes/home.tsx` imports and renders `<Logo />`
+- **THEN** it works without any changes to `home.tsx`
+
+### Requirement: Home screen layout SHALL be preserved
+The home screen layout structure (logo slot, prompt, bottom slot, footer slot) SHALL NOT change. Only the content rendered within slots changes.
+
+#### Scenario: Plugin slots are unchanged
+- **WHEN** a TUI plugin registers for `home_logo`, `home_prompt`, `home_bottom`, or `home_footer` slots
+- **THEN** the plugin works identically to before the rebrand
+
+### Requirement: Home screen placeholders SHALL reflect czcode context
+The prompt placeholder text arrays SHALL use czcode-appropriate suggestions.
+
+#### Scenario: Placeholder text is czcode-branded
+- **WHEN** the prompt is empty on the home screen
+- **THEN** placeholder text references czcode or ClickZetta Lakehouse capabilities
+
+### Requirement: Home tips SHALL show ClickZetta-relevant content
+The tips content strings SHALL reference ClickZetta Lakehouse workflows.
+
+#### Scenario: Tips reference Lakehouse workflows
+- **WHEN** tips are displayed on the home screen
+- **THEN** tip content references ClickZetta-relevant tasks
+
+### Requirement: Home footer SHALL display czcode version
+The version string in the home footer SHALL use czcode branding. Directory and MCP status display SHALL remain unchanged.
+
+#### Scenario: Footer shows czcode version
+- **WHEN** the home footer renders
+- **THEN** the version area shows "czcode" branding, not "opencode"

+## ADDED Requirements
+
+### Requirement: Session UI structure SHALL be fully preserved
+The sidebar (files, todo, context, MCP, LSP panels), Tab agent switching, keybinds, and all session layout SHALL remain unchanged. Only user-visible "opencode" text strings and theme colors change.
+
+#### Scenario: Sidebar panels are intact
+- **WHEN** the user opens the sidebar in a session
+- **THEN** all panels (files, todo, context, MCP, LSP) are present and functional
+
+#### Scenario: Tab agent switching works
+- **WHEN** the user presses Tab to switch agents
+- **THEN** agent switching works identically to upstream OpenCode
+
+### Requirement: Session footer SHALL not display OpenCode-specific messages
+The "Get started /connect" welcome message SHALL be removed. Any user-visible "opencode" text in the session footer SHALL be replaced with czcode branding.
+
+#### Scenario: No welcome message in session footer
+- **WHEN** the user enters a session without a connected provider
+- **THEN** the footer does not display "Get started /connect"
+
+### Requirement: Session chrome colors SHALL come from theme
+Session footer, sidebar, and permission prompt colors SHALL be determined by the active theme. No per-component color overrides SHALL be added for the rebrand.
+
+#### Scenario: Theme change applies globally
+- **WHEN** the czcode theme is active
+- **THEN** all session chrome elements use the czcode theme colors without per-file color changes

+## ADDED Requirements
+
+### Requirement: Default theme SHALL use ClickZetta brand colors
+A new theme file `czcode.json` SHALL be created alongside existing themes with ClickZetta brand colors. The primary accent color SHALL be `#1677FF`. The dark mode background SHALL use a cool dark tone. The neutral scale SHALL use cool gray tones.
+
+#### Scenario: Fresh install uses czcode theme
+- **WHEN** a user launches czcode for the first time with no theme configuration
+- **THEN** the TUI renders using the czcode theme with ClickZetta blue as the primary accent
+
+#### Scenario: Theme file is valid
+- **WHEN** the theme system loads `czcode.json`
+- **THEN** all required theme properties are defined and resolve to valid colors
+
+### Requirement: czcode theme SHALL be the default via one-line change
+The theme resolution logic SHALL select `czcode` as the default theme when no user preference is set. This SHALL be a single string change in the theme resolution code.
+
+#### Scenario: No theme configured
+- **WHEN** the user has not set a theme in their TUI config
+- **THEN** the theme system resolves to `czcode` as the active theme
+
+#### Scenario: User can still select other themes
+- **WHEN** the user sets a different theme in their TUI config
+- **THEN** that theme is applied instead of czcode
+
+### Requirement: Existing themes SHALL remain untouched
+All existing bundled themes SHALL NOT be modified. The `opencode.json` theme file SHALL be retained as-is for upstream compatibility.
+
+#### Scenario: opencode.json is unchanged
+- **WHEN** comparing `opencode.json` with the upstream version
+- **THEN** the files are identical

+## Business Architecture
+**Clickzetta consists of an engine layer and a data platform layer**:
+- **Engine Layer (Lakehouse)**: A data lake supporting lakehouse architecture with a SQL compute engine, containing schema, table metadata and data
+- **Data Platform Layer (Studio)**: Built on top of Lakehouse, exposing Lakehouse capabilities and providing task development, management, scheduling, data integration (import/export across engines), metadata management, data lineage, DQC, etc.
+
+## Terminology
+- "file", "task", "script", "job" all refer to **Clickzetta Task**; querying a job_id usually refers to the SQL engine's query ID
+- "directory", "folder" refer to **Clickzetta Folder**
+- Unless a specific engine type is specified, all SQL refers to Lakehouse SQL
+
+## Available Tools
+You have the cz-cli skill which provides direct access to Clickzetta Studio and Lakehouse:
+- Query workspaces, databases, schemas, tables and other metadata
+- Run SQL queries
+- Create, manage, and schedule tasks
+- Check task run status and logs
+
+When the user asks operational questions about Clickzetta (e.g. listing workspaces, running SQL, checking task status), you MUST proactively load the cz-cli skill and use it to take action, rather than asking the user for additional information.
 
 IMPORTANT: You must NEVER generate or guess URLs for the user unless you are confident that the URLs are for helping the user with programming. You may use URLs provided by the user in their messages or local files.
 
 If the user asks for help or wants to give feedback inform them of the following:
 - ctrl+p to list available actions
-- To give feedback, users should report the issue at
-  https://github.com/anomalyco/opencode
 
-When the user directly asks about OpenCode (eg. "can OpenCode do...", "does OpenCode have..."), or asks in second person (eg. "are you able...", "can you do..."), or asks how to use a specific OpenCode feature (eg. implement a hook, write a slash command, or install an MCP server), use the WebFetch tool to gather information to answer the question from OpenCode docs. The list of available docs is available at https://opencode.ai/docs
+When the user directly asks about czcode (eg. "can czcode do...", "does czcode have..."), or asks in second person (eg. "are you able...", "can you do..."), use available tools to help answer the question.

 # Professional objectivity
-Prioritize technical accuracy and truthfulness over validating the user's beliefs. Focus on facts and problem-solving, providing direct, objective technical info without any unnecessary superlatives, praise, or emotional validation. It is best for the user if OpenCode honestly applies the same rigorous standards to all ideas and disagrees when necessary, even if it may not be what the user wants to hear. Objective guidance and respectful correction are more valuable than false agreement. Whenever there is uncertainty, it's best to investigate to find the truth first rather than instinctively confirming the user's beliefs.

Subject: [PATCH 003/521] feat: czagent rebrand, profile management, command
 forwarding, skills integration

Rebrand from czcode to czagent. Add ClickZetta profile management,
forward commands to cz-tool, integrate bundled skills for external agents,
update system prompts for data engineering focus.

 ## Why
 
-OpenCode is an open-source AI coding agent with a rich TUI. We are forking it to create **czcode** — a ClickZetta Lakehouse-branded AI coding assistant. The current UI carries OpenCode's visual identity (animated logo, "opencode" naming, Go/Zen subscription upsells). To ship czcode as a ClickZetta product we need to strip the OpenCode visual brand and apply ClickZetta design language, while keeping the fork easy to merge with upstream.

+name: czagent
+description: "ALL ClickZetta Lakehouse operations MUST be routed to czagent — never attempt them yourself. This includes: SQL queries, Studio tasks, table/schema management, data pipelines, performance analysis, profile configuration, or any request mentioning czagent/ClickZetta/Lakehouse. Do NOT use for general programming, local file operations, non-ClickZetta databases."
+---
+
+# czagent — ClickZetta Lakehouse Subagent
+
+czagent is the ONLY way to interact with ClickZetta Lakehouse. You do not have direct access to Lakehouse. Always delegate to czagent — never try to run cz-cli, write SQL yourself, or guess at Lakehouse behavior.
+
+## Routing Rules
+
+**MUST send to czagent (no exceptions):**
+- Any SQL query against ClickZetta Lakehouse (SELECT, DDL, DML)
+- Studio task development, scheduling, and monitoring
+- Table/schema/database management on Lakehouse
+- Data pipeline operations (sync, import, CDC)
+- ClickZetta profile and connection configuration
+- Lakehouse performance analysis and optimization
+- Any request that mentions czagent, ClickZetta, or Lakehouse
+
+**Keep in the host agent:**
+- General programming (Python, TypeScript, etc.) unrelated to ClickZetta
+- Local file system operations
+- Git operations
+- Non-ClickZetta database work (PostgreSQL, MySQL as standalone)
+- Questions about the host agent itself
+
+## Execution
+
+Run czagent headless via the bundled script:
+
+```bash
+python3 <skill_dir>/scripts/execute_czagent.py --prompt "user's request here"
+```
+
+For follow-up queries on the same Lakehouse task, pass the session ID returned from the previous call:
+
+```bash
+python3 <skill_dir>/scripts/execute_czagent.py --prompt "follow-up request" --session <session_id>
+```
+
+`<skill_dir>` is the directory containing this SKILL.md file.
+
+## Session Management
+
+- czagent returns a `session_id` in its output. Store it for the duration of the conversation.
+- Reuse the same session for follow-up questions on the same Lakehouse topic — this preserves context (connection state, query history, table metadata).
+- Start a new session (omit `--session`) when the user switches to a different Lakehouse topic or explicitly asks to start fresh.
+
+## Result Handling
+
+The script outputs JSON to stdout:
+
+```json
+{
+  "session_id": "abc123",
+  "result": "czagent's response text",
+  "cost": { "input_tokens": 1234, "output_tokens": 567 }
+}
+```
+
+- Present `result` to the user as-is. Do not re-summarize unless the user asks.
+- If the result contains SQL output or tables, preserve formatting.
+- If czagent reports an error, relay it and suggest the user check their ClickZetta profile (`czagent profile`).
+
+## Fast Path
+
+For simple follow-ups ("show me the next 10 rows", "run that again with WHERE clause"), execute immediately with the existing session. No need to re-confirm routing or re-explain what czagent is.

+# cz-cli TypeScript 全量重写 Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Rewrite the Python cz-cli into TypeScript across three packages (clickzetta-sdk, cz-cli, opencode modifications), eliminating the Python dependency while preserving all CLI commands and behavior.
+
+**Architecture:** Three-layer monorepo packages — `clickzetta-sdk` (HTTP client + types), `cz-cli` (CLI commands compiled to `cz-tool` binary), and `opencode` modifications (rename to `czcli`, route `agent` to opencode, others to `cz-tool`, register `cz-tool` as built-in tool). All ClickZetta backend communication is standard HTTP REST with JSON bodies and `X-Clickzetta-Token` auth.
+
+**Tech Stack:** TypeScript, Bun, yargs (CLI), smol-toml (TOML), Effect (in opencode tool layer), Zod (schemas)
+
+**Source Reference:** Python implementation at `~/code/cz-cli/` — all behavior must match 1:1.

+
+## Task 1: Scaffold `packages/clickzetta-sdk` package
+
+**Files:**
+- Create: `packages/clickzetta-sdk/package.json`
+- Create: `packages/clickzetta-sdk/tsconfig.json`
+- Create: `packages/clickzetta-sdk/src/index.ts`
+- Create: `packages/clickzetta-sdk/src/types/index.ts`
+- Create: `packages/clickzetta-sdk/src/types/api.ts`
+
+- [ ] **Step 1: Create package.json**
+
+```json
+{
+  "name": "@clickzetta/sdk",
+  "version": "0.1.0",
+  "private": true,
+  "type": "module",
+  "exports": {
+    ".": "./src/index.ts"
+  },
+  "dependencies": {
+    "smol-toml": "catalog:"
+  },
+  "devDependencies": {
+    "typescript": "catalog:"
+  }
+}
+```
+
+- [ ] **Step 2: Create tsconfig.json**
+
+Reference the root tsconfig pattern from other packages in the monorepo. Check `packages/opencode/tsconfig.json` for the exact extends path and compiler options, then mirror them.
+
+- [ ] **Step 3: Create core types in `src/types/index.ts`**
+
+Port from Python `connection.py` ConnectionConfig dataclass:
+
+```typescript
+export interface ConnectionConfig {
+  pat: string

+
+- [ ] **Step 4: Implement token management**
+
+Port expiry logic from Python `client.py` lines 1473-1481 (DEFAULT_EXPIRED_FACTOR = 0.8).
+
+`packages/clickzetta-sdk/src/auth/token.ts`:

+## Task 3: Implement SQL execution module in SDK
+
+**Files:**
+- Create: `packages/clickzetta-sdk/src/sql/types.ts`
+- Create: `packages/clickzetta-sdk/src/sql/submit.ts`
+- Create: `packages/clickzetta-sdk/src/sql/poll.ts`
+- Create: `packages/clickzetta-sdk/src/sql/cancel.ts`
+- Create: `packages/clickzetta-sdk/src/sql/split.ts`
+
+- [ ] **Step 1: Create SQL types**
+
+Port from Python `client.py` JobID, QueryResult, QueryDataType, and status enums.
+
+`packages/clickzetta-sdk/src/sql/types.ts`:
+
+```typescript
+export interface JobID {
+  id: string
+}
+
+export enum JobStatus {
+  SUBMITTED = "SUBMITTED",
+  RUNNING = "RUNNING",
+  SUCCEEDED = "SUCCEEDED",
+  FAILED = "FAILED",
+  CANCELLED = "CANCELLED",
+  UNKNOWN = "UNKNOWN",
+}
+
+export interface ColumnSchema {
+  name: string
+  type: string
+}
+
+export interface QueryResult {
+  jobId: string
+  status: JobStatus
+  columns: ColumnSchema[]
+  rows: Record<string, unknown>[]
+  rowCount: number
+  affectedRows: number
+  errorCode?: string
+  errorMessage?: string
+}
+
+export function newJobId(): string {

+    .map((b) => b.toString(16).padStart(2, "0"))
+    .join("")
+  return `tssdk-${hex}`
+}
+```
+
+- [ ] **Step 2: Implement submitJob**
+
+Port from Python `client.py` lines 569-700. Reference the exact request body structure.
+
+`packages/clickzetta-sdk/src/sql/submit.ts` — read Python `client.py` `submit_sql_job()` and `_handle_submit_sql()` for the exact JSON body fields (`jobId`, `sql`, `workspace`, `instance`, `vcluster`, `schema`, `jobType`, `requestMode`, `hints`, etc.), then implement the equivalent POST to `/lh/submitJob`.
+
+- [ ] **Step 3: Implement getJob (poll)**
+
+Port from Python `client.py` `_get_query_result()`. Polls `/lh/getJob` until status is terminal.
+
+`packages/clickzetta-sdk/src/sql/poll.ts` — implement polling loop with configurable timeout (default 30s polling interval matching Python's `polling_timeout`). Parse the response into `QueryResult` with columns and rows.
+
+- [ ] **Step 4: Implement cancelJob**
+
+Port from Python `client.py` lines 1088-1100.
+
+`packages/clickzetta-sdk/src/sql/cancel.ts`:

+    jobId,
+    instanceId,
+  })
+}
+```
+
+- [ ] **Step 5: Implement SQL splitting**
+
+Port from Python `clickzetta.connector.v0.utils.split_sql`. Read the Python source at `/opt/homebrew/lib/python3.14/site-packages/clickzetta/connector/v0/utils.py` for the exact logic (handles quoted strings, comments, semicolons).
+
+`packages/clickzetta-sdk/src/sql/split.ts` — implement `splitSql(sql: string): string[]` that handles:
+- Single-line comments (`--`)
+- Multi-line comments (`/* */`)
+- Quoted strings (single and double quotes, with escape handling)
+- Semicolon as statement delimiter
+- Strips empty statements
+
+- [ ] **Step 6: Update index.ts exports**
+
+Add to `packages/clickzetta-sdk/src/index.ts`:
+
+```typescript
+export * from "./sql/types.js"
+export * from "./sql/submit.js"
+export * from "./sql/poll.js"
+export * from "./sql/cancel.js"
+export * from "./sql/split.js"
+```

+
+## Task 5: Scaffold `packages/cz-cli` and implement connection/output layer
+
+**Files:**
+- Create: `packages/cz-cli/package.json`
+- Create: `packages/cz-cli/tsconfig.json`
+- Create: `packages/cz-cli/src/index.ts`
+- Create: `packages/cz-cli/src/version.ts`
+- Create: `packages/cz-cli/src/connection/jdbc.ts`
+- Create: `packages/cz-cli/src/connection/profile-store.ts`
+- Create: `packages/cz-cli/src/connection/config.ts`
+- Create: `packages/cz-cli/src/output/masking.ts`
+- Create: `packages/cz-cli/src/output/formatter.ts`
+- Create: `packages/cz-cli/src/output/index.ts`
+- Create: `packages/cz-cli/src/logger.ts`
+
+- [ ] **Step 1: Create package.json**
+
+```json
+{
+  "name": "@clickzetta/cli",
+  "version": "0.1.0",
+  "private": true,
+  "type": "module",
+  "exports": {
+    ".": "./src/index.ts"
+  },
+  "dependencies": {
+    "@clickzetta/sdk": "workspace:*",
+    "smol-toml": "catalog:",
+    "yargs": "catalog:"
+  },
+  "devDependencies": {
+    "@types/yargs": "catalog:",
+    "typescript": "catalog:"
+  }
+}
+```
+
+- [ ] **Step 2: Create tsconfig.json and version.ts**
+
+Mirror tsconfig from clickzetta-sdk.
+
+`packages/cz-cli/src/version.ts`:
+```typescript
+export const VERSION = "0.1.0"
+```
+
+- [ ] **Step 3: Implement JDBC URL parsing**
+
+Port from Python `connection.py` `_parse_jdbc_url()`. Format: `jdbc:clickzetta://<instance>.<service>/<workspace>?params`.
+
+`packages/cz-cli/src/connection/jdbc.ts`:
+
+```typescript
+import type { ConnectionConfig } from "@clickzetta/sdk"
+
+export function parseJdbcUrl(
+  jdbc: string,
+): Partial<ConnectionConfig> | undefined {
+  let url = jdbc
+  if (url.startsWith("jdbc:")) url = url.slice(5)
+  let parsed: URL
+  try {
+    parsed = new URL(url)
+  } catch {
+    return undefined
+  }
+
+  const hostParts = parsed.hostname.split(".")
+  if (hostParts.length < 4) return undefined
+
+  const instance = hostParts[0]
+  const service = hostParts.slice(1).join(".")
+  const workspace = parsed.pathname.replace(/^\//, "") || undefined
+  const params = parsed.searchParams
+
+  const result: Partial<ConnectionConfig> = {
+    instance,
+    service,
+  }
+  if (workspace) result.workspace = workspace
+  if (params.get("username")) result.username = params.get("username")!
+  if (params.get("password")) result.password = params.get("password")!
+  if (params.get("schema")) result.schema = params.get("schema")!
+  if (params.get("virtualCluster")) result.vcluster = params.get("virtualCluster")!
+  if (params.get("workspace")) result.workspace = params.get("workspace")!
+  if (params.get("protocol")) result.protocol = params.get("protocol")!
+
+  return result
+}
+```
+
+- [ ] **Step 4: Implement profile store**
+
+Port from Python `connection.py` `_load_profiles()`, `_save_profiles()`. Uses `smol-toml` for TOML parsing. Atomic writes via temp file + rename.
+
+`packages/cz-cli/src/connection/profile-store.ts` — implement:
+- `loadProfiles(): Record<string, ProfileEntry>`
+- `saveProfiles(profiles: Record<string, ProfileEntry>): void`
+- `getDefaultProfileName(): string | undefined`
+- `getProfileConfig(name?: string): Partial<ConnectionConfig> | undefined`
+- File path: `~/.clickzetta/profiles.toml`
+- Handle custom headers: nested dict (`header.X = Y`) and dotted keys
+
+- [ ] **Step 5: Implement connection config resolution**
+
+Port the priority chain from Python `connection.py` `resolve_connection_config()`.
+
+`packages/cz-cli/src/connection/config.ts` — implement:
+- `resolveConnectionConfig(cliArgs): ConnectionConfig`
+- Priority for non-auth fields: profile → env → JDBC → CLI args (later wins)
+- Priority for auth: CLI PAT > env PAT > profile PAT > CLI user/pass > JDBC user/pass > env user/pass > profile user/pass
+- If PAT is set, clear username/password
+- Environment variables: `CZ_PAT`, `CZ_USERNAME`, `CZ_PASSWORD`, `CZ_SERVICE`, `CZ_PROTOCOL`, `CZ_INSTANCE`, `CZ_WORKSPACE`, `CZ_SCHEMA`, `CZ_VCLUSTER`
+
+- [ ] **Step 6: Implement sensitive data masking**
+
+Port from Python `masking.py`. Exact same regex patterns and masking logic.
+
+`packages/cz-cli/src/output/masking.ts`:
+
+```typescript
+const PHONE_PATTERN = /phone|mobile|tel|cellphone/i
+const EMAIL_PATTERN = /email|e_mail/i
+const PASSWORD_PATTERN = /password|passwd|secret|api_key|apikey/i
+const IDCARD_PATTERN = /id_card|idcard|id_number|identity|ssn|national_id/i
+
+function maskPhone(val: string): string {
+  const digits = val.replace(/\D/g, "")
+  if (digits.length >= 7) return digits.slice(0, 3) + "****" + digits.slice(-4)
+  return "****"
+}
+
+function maskEmail(val: string): string {
+  const at = val.lastIndexOf("@")
+  if (at < 0) return "******"
+  const local = val.slice(0, at)
+  const domain = val.slice(at + 1)
+  if (local.length > 1) return local[0] + "***@" + domain
+  return "***@" + domain
+}
+
+function maskPassword(_val: string): string {
+  return "******"
+}
+
+function maskIdcard(val: string): string {
+  if (val.length >= 6) {
+    return val.slice(0, 3) + "*".repeat(Math.max(val.length - 7, 1)) + val.slice(-4)
+  }
+  return "****"
+}
+
+type Masker = (val: string) => string
+
+function getMasker(column: string): Masker | undefined {
+  if (PHONE_PATTERN.test(column)) return maskPhone
+  if (EMAIL_PATTERN.test(column)) return maskEmail
+  if (PASSWORD_PATTERN.test(column)) return maskPassword
+  if (IDCARD_PATTERN.test(column)) return maskIdcard
+  return undefined
+}
+
+export function maskRows(
+  columns: string[],
+  rows: Record<string, unknown>[],
+): Record<string, unknown>[] {
+  const maskers = new Map<string, Masker>()
+  for (const col of columns) {
+    const m = getMasker(col)
+    if (m) maskers.set(col, m)
+  }
+  if (maskers.size === 0) return rows
+  for (const row of rows) {
+    for (const [col, masker] of maskers) {
+      if (typeof row[col] === "string") {
+        row[col] = masker(row[col] as string)
+      }
+    }
+  }
+  return rows
+}
+```
+
+- [ ] **Step 7: Implement output formatter**
+
+Port from Python `output.py`. Implement all 6 formats: json, pretty, table, csv, jsonl, toon.
+
+`packages/cz-cli/src/output/formatter.ts` — implement:
+- `formatJson(data)` — compact JSON
+- `formatPretty(data)` — indented JSON (2 spaces)
+- `formatTable(columns, rows)` — ASCII table with column alignment
+- `formatCsv(columns, rows)` — CSV with header row
+- `formatJsonl(rows)` — one JSON object per line
+- `formatToon(data)` — if toons library available, else fall back to JSON
+
+`packages/cz-cli/src/output/index.ts` — implement:
+- `success(data, opts)` — wraps in `{ok: true, data, time_ms, count, ai_message}`, prints, exits 0
+- `successRows(columns, rows, opts)` — wraps in `{ok: true, columns, rows, count, affected, time_ms}`, prints, exits 0
+- `error(code, message, opts)` — wraps in `{ok: false, error: {code, message}}`, prints, exits 1
+- Exit codes: `EXIT_OK = 0`, `EXIT_BIZ_ERROR = 1`, `EXIT_USAGE_ERROR = 2`
+- Color detection: respect `NO_COLOR`, `CZ_FORCE_COLOR`, `CLICOLOR_FORCE`, fallback to `isatty()`
+
+- [ ] **Step 8: Implement operation logger**
+
+Port from Python `logger.py`. Writes to `~/.clickzetta/sql-history.jsonl`.
+
+`packages/cz-cli/src/logger.ts` — implement:
+- `logOperation(command, opts)` — appends JSONL entry
+- `redactSql(sql)` — redact sensitive literals in SQL (phone, idcard, email, passwords near sensitive column names)
+- Regex patterns: same as Python version
+- Silent failure on write errors
+- Creates directory if needed
+
+- [ ] **Step 9: Run `bun install` and verify compilation**
+
+Run: `bun install && cd packages/cz-cli && bunx tsc --noEmit`
+Expected: No errors.
+
+- [ ] **Step 10: Commit**
+
+```bash
+git add packages/cz-cli/
+git commit -m "feat(cz-cli): scaffold package, connection config, output formatting, masking, logger"
+```

+
+## Task 6: Implement cz-cli yargs root and global options
+
+**Files:**
+- Create: `packages/cz-cli/src/cli.ts`
+- Modify: `packages/cz-cli/src/index.ts`
+
+- [ ] **Step 1: Implement yargs root with global options injection**
+
+Port from Python `main.py` and `cli_group.py`. The root group auto-injects connection, output, and debug options into all subcommands.
+
+`packages/cz-cli/src/cli.ts`:
+
+```typescript
+import yargs from "yargs"
+import { hideBin } from "yargs/helpers"
+import { VERSION } from "./version.js"
+import { resolveConnectionConfig } from "./connection/config.js"
+
+export interface GlobalArgs {
+  profile?: string
+  jdbc?: string
+  pat?: string
+  username?: string
+  password?: string
+  service?: string
+  protocol?: string
+  instance?: string
+  workspace?: string
+  schema?: string
+  vcluster?: string
+  output: string
+  debug: boolean
+  silent: boolean
+  verbose: boolean
+}
+
+export function createCli(args: string[]) {
+  return yargs(args)
+    .scriptName("cz-tool")
+    .version(VERSION)
+    .option("profile", {
+      alias: "p",
+      type: "string",
+      describe: "Profile name from ~/.clickzetta/profiles.toml",
+    })
+    .option("jdbc", {
+      type: "string",
+      describe: "JDBC connection URL",
+    })
+    .option("pat", {

+      describe: "Service endpoint",
+    })
+    .option("protocol", {
+      type: "string",
+      describe: "Protocol (https/http)",
+    })
+    .option("instance", {
+      type: "string",
+      describe: "Instance name",
+    })
+    .option("workspace", {
+      type: "string",
+      describe: "Workspace name",
+    })
+    .option("schema", {
+      alias: "s",
+      type: "string",
+      describe: "Default schema",
+    })
+    .option("vcluster", {
+      alias: "v",
+      type: "string",
+      describe: "Virtual cluster",
+    })
+    .option("output", {
+      alias: "o",
+      type: "string",
+      choices: ["json", "pretty", "table", "csv", "jsonl", "toon"],
+      default: "json",
+      describe: "Output format",
+    })
+    .option("debug", {
+      alias: "d",
+      type: "boolean",
+      default: false,
+      describe: "Enable debug mode",
+    })
+    .option("silent", {
+      type: "boolean",
+      default: false,
+      describe: "Suppress non-essential output",
+    })
+    .option("verbose", {
+      type: "boolean",
+      default: false,
+      describe: "Verbose output",
+    })
+    .strict()
+    .fail((msg, err) => {
+      const output = JSON.stringify({
+        ok: false,
+        error: { code: "USAGE_ERROR", message: msg || err?.message },
+      })
+      process.stderr.write(output + "\n")
+      process.exit(2)
+    })
+}
+```
+
+- [ ] **Step 2: Create entry point**
+
+`packages/cz-cli/src/index.ts`:
+
+```typescript
+#!/usr/bin/env bun
+import { createCli } from "./cli.js"
+
+const cli = createCli(process.argv.slice(2))
+
+// Commands will be registered in subsequent tasks
+// For now, just parse and show help
+cli.demandCommand(1, "").help().parse()
+```
+
+- [ ] **Step 3: Verify it runs**
+
+Run: `cd packages/cz-cli && bun src/index.ts --help`
+Expected: Shows help with all global options listed.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add packages/cz-cli/src/cli.ts packages/cz-cli/src/index.ts
+git commit -m "feat(cz-cli): yargs root with global options"
+```

+
+## Task 7: Implement core CLI commands (sql, schema, table, workspace, status)
+
+**Files:**
+- Create: `packages/cz-cli/src/commands/sql.ts`
+- Create: `packages/cz-cli/src/commands/schema.ts`
+- Create: `packages/cz-cli/src/commands/table.ts`
+- Create: `packages/cz-cli/src/commands/workspace.ts`
+- Create: `packages/cz-cli/src/commands/status.ts`
+- Modify: `packages/cz-cli/src/index.ts` (register commands)
+
+- [ ] **Step 1: Implement sql command**
+
+Port from Python `commands/sql.py`. This is the most complex command. Must include:
+- All options: `--write`, `--with-schema`, `--no-truncate`, `-f`, `-e`, `--stdin`, `--sync`, `--timeout`, `--variable`, `--set`, `--job-profile`, `-N`, `--no-limit`, `-B`
+- Safety guardrails: write protection (require `--write` for INSERT/UPDATE/DELETE/etc.), dangerous write detection (DELETE/UPDATE without WHERE), automatic LIMIT 100 injection
+- Multi-statement support via `splitSql()`
+- Variable substitution (`%(key)s` format)
+- Sensitive data masking via `maskRows()`
+- Async mode: submit and return job_id without waiting
+- Field truncation (3000 chars default)
+- Schema hints on error
+
+Read `~/code/cz-cli/cz_cli/commands/sql.py` for the exact regex patterns:
+- `_WRITE_RE`: matches INSERT, UPDATE, DELETE, REPLACE, ALTER, CREATE, DROP, TRUNCATE, RENAME, FORK
+- `_SELECT_RE`: matches SELECT, SHOW, DESC, DESCRIBE, EXPLAIN
+- `_LIMIT_RE`: matches existing LIMIT clause
+- `_DANGEROUS_WRITE_RE`: DELETE/UPDATE without WHERE
+
+- [ ] **Step 2: Implement schema command**
+
+Port from Python `commands/schema.py`. Four subcommands using SQL queries:
+- `list`: `SHOW SCHEMAS` + optional `LIKE '{pattern}'`, client-side limit
+- `describe`: `SHOW SCHEMAS EXTENDED WHERE schema_name='{name}'` + `SHOW TABLES IN {name}`
+- `create`: `CREATE SCHEMA {name}`
+- `drop`: `DROP SCHEMA {name}`
+
+- [ ] **Step 3: Implement table command**
+
+Port from Python `commands/table.py`. Seven subcommands:
+- `list`: `SHOW TABLES` + optional `IN {schema}` + `LIKE '{pattern}'` + `LIMIT {limit+1}` (probe for truncation)
+- `describe`: `DESC TABLE {name}`
+- `preview`: `SELECT * FROM {name} LIMIT {limit}`
+- `stats`: `SELECT COUNT(*) as row_count FROM {name}`
+- `history`: `SHOW TABLES HISTORY` + filters
+- `create`: Execute raw DDL (inline or from file)
+- `drop`: `DROP TABLE {name}`
+
+- [ ] **Step 4: Implement workspace command**
+
+Port from Python `commands/workspace.py`. Two subcommands:
+- `current`: Execute `SELECT current_workspace()`, return `{workspace: name}`
+- `use`: Set workspace via SDK hint `sdk.job.default.ns`, optional `--persist` to update profile TOML
+
+- [ ] **Step 5: Implement status command**
+
+Port from Python `main.py` status command:
+- Execute `SELECT current_workspace()` and `SELECT current_schema()`
+- Return `{ok, connected, workspace, schema, cli_version, time_ms}`
+- Handle connection errors gracefully
+
+- [ ] **Step 6: Register all commands in index.ts**
+
+Update `packages/cz-cli/src/index.ts` to register sql, schema, table, workspace, status commands with the yargs CLI.
+
+- [ ] **Step 7: Verify compilation**
+
+Run: `cd packages/cz-cli && bunx tsc --noEmit`
+Expected: No type errors.
+
+- [ ] **Step 8: Commit**
+
+```bash

+- `wait`: Poll until run completes (with timeout)
+- `logs`: Get run logs (alias for attempts log)
+- `deps`: View run dependencies
+- `stop`: Stop running instance
+- `stats`: Run statistics summary
+- `refill`: Submit backfill job
+
+Status/type mappings: `SUCCESS=1, WAITING=2, FAILED=3, RUNNING=4`, `SCHEDULE=1, TEMP=3, REFILL=4`
+
+- [ ] **Step 4: Implement attempts command**
+
+Port from Python `commands/attempts.py`. Two subcommands:
+- `list`: List attempt records by run_id or task_name, auto-select latest run if not specified
+- `log` (alias `logs`): Get attempt log with optional `--attempt-id` and `--offset`

+
+- [ ] **Step 7: Register all commands in index.ts**
+
+Update `packages/cz-cli/src/index.ts` to register profile, task, runs, attempts, agent, job commands.
+
+- [ ] **Step 8: Verify compilation**

+
+`packages/cz-cli/src/guide-builder.ts` — implement:
+- `buildAiGuide(cli, options)`: Walk the yargs command tree, extract command names, descriptions, options, arguments
+- `--wide` mode: include per-command option details
+- Output structure: `{version, commands: [{name, description, options?, arguments?}]}`
+
+- [ ] **Step 2: Implement ai-guide command**
+
+Port from Python `main.py` ai-guide command.
+

+- Modify: `packages/opencode/src/index.ts`
+- Modify: `packages/opencode/src/cli/cmd/forward.ts`
+- Modify: `packages/opencode/src/cli/cmd/tui/brand.ts`
+- Modify: `packages/opencode/src/installation/index.ts`
+- Delete: `packages/opencode/src/cli/cmd/profile.ts`
+- Delete: `packages/opencode/src/profile/index.ts`
+- Modify: `packages/opencode/package.json`
+
+- [ ] **Step 1: Update brand.ts**
+
+Change binary name from `czagent` to `czcli`:
+
+```typescript
+export const brand = {
+  name: "czcli",
+  display: "CZAgent",
+  company: "ClickZetta",
+}
+```
+
+- [ ] **Step 2: Update index.ts entry point**
+
+Modify `packages/opencode/src/index.ts`:
+- Change `.scriptName("czagent")` to `.scriptName("czcli")`
+- Add `agent` as a command that wraps the current TUI/run logic
+- Keep forward commands for non-agent subcommands (sql, task, runs, etc.)
+- Remove profile command registration (now handled by cz-tool)
+- Remove profile middleware check (cz-tool handles its own profile resolution)
+
+- [ ] **Step 3: Update forward.ts**
+
+Update `packages/opencode/src/cli/cmd/forward.ts`:
+- `resolveCzTool()` should look for the new TS-compiled cz-tool binary at the same relative path (`{binDir}/cz-tool/cz-tool`)
+- No other changes needed — the forwarding mechanism stays the same
+
+- [ ] **Step 4: Clean up installation/index.ts**
+
+Remove all Python cz-cli download/install logic from `packages/opencode/src/installation/index.ts`:
+- Remove `downloadCzCli()` or equivalent functions
+- Remove GitHub release fetching for cz-cli
+- Remove PyInstaller binary extraction
+- Keep any other installation logic (skills, config setup)
+
+- [ ] **Step 5: Delete redundant profile code**
+
+Delete:
+- `packages/opencode/src/cli/cmd/profile.ts`
+- `packages/opencode/src/profile/index.ts`
+- `packages/opencode/src/profile/` directory
+
+Remove imports and references to these files from `index.ts`.
+
+- [ ] **Step 6: Add clickzetta-sdk dependency**
+
+Update `packages/opencode/package.json` to add:
+```json
+"@clickzetta/sdk": "workspace:*"
+```
+
+This allows opencode to directly call SDK functions (e.g., for profile verification in the future).
+
+- [ ] **Step 7: Verify compilation**
+
+Run: `cd packages/opencode && bunx tsc --noEmit`
+Expected: No type errors.
+
+- [ ] **Step 8: Commit**
+
+```bash
+git add packages/opencode/
+git commit -m "refactor(opencode): rename to czcli, update routing, remove Python cz-cli deps"
+```
+
+---
+
+## Task 11: Register cz-tool as opencode built-in tool
+
+**Files:**
+- Create: `packages/opencode/src/tool/cz-tool.ts`
+- Modify: `packages/opencode/src/tool/registry.ts`
+
+- [ ] **Step 1: Implement cz-tool tool definition**
+
+Create `packages/opencode/src/tool/cz-tool.ts` following the existing tool pattern (Effect-based, Zod schema). Reference `packages/opencode/src/tool/bash.ts` for the exact pattern.
+
+The tool should:
+- Accept a `command` parameter (string, e.g., "sql -e 'SELECT 1'" or "table list")
+- Accept optional `profile` parameter
+- Spawn the cz-tool binary with the given command args
+- Capture stdout/stderr
+- Return structured output (parse JSON from cz-tool stdout)
+- Use `--output json` to ensure machine-readable output
+- Respect the agent's abort signal
+
+Zod parameters schema:
+
+```typescript
+const Parameters = z.object({
+  command: z.string().describe(
+    "The cz-tool command to execute, e.g. 'sql -e \"SELECT 1\"' or 'table list --like users'"
+  ),
+  profile: z.string().optional().describe("Profile name to use"),
+})
+```
+
+- [ ] **Step 2: Register in tool registry**
+
+Modify `packages/opencode/src/tool/registry.ts`:
+- Import the cz-tool definition
+- Add it to the builtin tools array alongside bash, read, write, etc.
+
+- [ ] **Step 3: Verify compilation**
+
+Run: `cd packages/opencode && bunx tsc --noEmit`
+Expected: No type errors.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add packages/opencode/src/tool/cz-tool.ts packages/opencode/src/tool/registry.ts
+git commit -m "feat(opencode): register cz-tool as built-in tool for agent"
+```
+
+---
+
+## Task 12: Update build system
+
+**Files:**
+- Modify: `packages/opencode/script/build.ts`
+- Modify: `Makefile`
+- Modify: `scripts/setup.sh`
+
+- [ ] **Step 1: Update build.ts to compile cz-tool**
+
+Modify `packages/opencode/script/build.ts`:
+- Before compiling the main `czcli` binary, compile `packages/cz-cli/src/index.ts` into `cz-tool` binary using `Bun.build()` with `compile: true`
+- Output to `dist/{platform}/bin/cz-tool/cz-tool`
+- Remove the section that downloads Python cz-cli from GitHub releases
+- Remove skills.tar.gz bundling (skills are now part of the TS package)
+
+Build cz-tool:
+```typescript
+await Bun.build({
+  entrypoints: ["../../cz-cli/src/index.ts"],
+  outdir: `dist/${name}/bin/cz-tool`,
+  compile: {
+    target: name.replace(pkg.name, "bun"),
+    outfile: `dist/${name}/bin/cz-tool/cz-tool`,
+  },
+  define: {
+    CZ_TOOL_VERSION: `'${Script.version}'`,
+  },
+})
+```
+
+- [ ] **Step 2: Update Makefile**
+
+Update the `build` target to:
+- Remove Python cz-cli download step
+- The Bun build now produces both `czcli` and `cz-tool` binaries
+- Update output binary name from `czcode` to `czcli`
+- Update zip/tar naming
+
+- [ ] **Step 3: Update setup.sh**
+
+Modify `scripts/setup.sh`:
+- Install `czcli` binary to `~/.local/bin/czcli`
+- Create symlinks: `cz` → `czcli`, `cz-cli` → `czcli`, `clickzetta-cli` → `czcli`
+- Install `cz-tool` to `~/.local/bin/cz-tool/cz-tool` (or alongside czcli)
+- Remove Python cz-cli installation steps
+- Remove `pip install` or PyInstaller binary extraction
+- Keep skills installation and config setup
+
+- [ ] **Step 4: Test build locally**
+
+Run: `make build`
+Expected: Produces `czcli` and `cz-tool` binaries in `out/` directory.
+
+- [ ] **Step 5: Smoke test**
+
+Run: `./out/czcli-darwin-arm64/czcli --version`
+Expected: Shows version.
+
+Run: `./out/czcli-darwin-arm64/czcli sql --help`
+Expected: Shows SQL command help (forwarded to cz-tool).
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add packages/opencode/script/build.ts Makefile scripts/setup.sh
+git commit -m "build: compile cz-tool from TS, remove Python cz-cli bundling"
+```
+
+---
+
+## Task 13: End-to-end verification
+
+**Files:** None (testing only)
+
+- [ ] **Step 1: Verify cz-tool standalone**
+
+Run: `cd packages/cz-cli && bun src/index.ts --help`
+Expected: Shows all commands and global options.
+
+Run: `cd packages/cz-cli && bun src/index.ts status --profile <test-profile>`
+Expected: Shows connection status or appropriate error.
+
+- [ ] **Step 2: Verify czcli routing**
+
+Run: `cd packages/opencode && bun src/index.ts sql --help`
+Expected: Forwards to cz-tool, shows SQL help.
+
+Run: `cd packages/opencode && bun src/index.ts agent --help`
+Expected: Shows opencode agent help (TUI, run, etc.).
+
+- [ ] **Step 3: Verify profile operations**
+
+Run: `cd packages/cz-cli && bun src/index.ts profile list`
+Expected: Lists profiles from `~/.clickzetta/profiles.toml`.
+
+- [ ] **Step 4: Verify SQL execution (if test profile available)**
+
+Run: `cd packages/cz-cli && bun src/index.ts sql -e "SELECT 1" --profile <test-profile>`
+Expected: Returns `{ok: true, columns: [...], rows: [{...}], count: 1}`.
+
+- [ ] **Step 5: Verify output formats**
+
+Run: `cd packages/cz-cli && bun src/index.ts profile list --output pretty`
+Run: `cd packages/cz-cli && bun src/index.ts profile list --output table`
+Run: `cd packages/cz-cli && bun src/index.ts profile list --output csv`
+Expected: Each format renders correctly.
+
+- [ ] **Step 6: Verify cz-tool as opencode tool**
+
+Start opencode TUI, ask the agent to "list my ClickZetta tables". Verify it invokes the cz-tool built-in tool.
+
+- [ ] **Step 7: Final commit**
+
+```bash
+git add -A
+git commit -m "feat: complete cz-cli TypeScript rewrite — eliminate Python dependency"
+```

Subject: [PATCH 012/521] fix(cz-cli): review fixes for core CLI commands

- Fix sql.ts executeSingle() fall-through causing double SQL execution
- Fix dead LIMIT probe code (SELECT with user LIMIT N now probes N+1)
- Wire --no-header flag through to successRows output
- Escape single quotes in --like parameters to prevent SQL injection
- Change schema list to truncate with aiMessage instead of hard error
- Add formatTableNoHeader and formatCsvNoHeader formatters
- Use top-level imports instead of inline require for node:fs

Subject: [PATCH 013/521] fix(cz-cli): identifier validation and silent failure
 handling

- Add validateIdentifier() to prevent SQL injection via table/schema names
- Validate all identifier interpolations in schema.ts and table.ts
- Validate regex-extracted table names in sql.ts fetchSchemaHint/fetchWithSchema
- Replace silent returns with explicit errors when sync execSql returns async marker

Subject: [PATCH 015/521] fix(cz-cli): spec review fixes for attempts, task
 execute, runs stats

- attempts: make --run-id optional, accept --task-id with auto-select
  latest run, make --attempt-id optional with auto-select first attempt,
  add `logs` alias for `log` command
- task: add `execute` subcommand for ad-hoc task execution via SDK
- runs: add `rerun` subcommand, add `stats` subcommand with per-status
  counts over time range

Subject: [PATCH 016/521] fix(cz-cli): code quality fixes for agent, job, runs
 commands

- agent: hoist auth resolution to avoid redundant getToken() call
- job: use error() instead of success() for not-implemented placeholder
- runs: remove unused --offset option from logs subcommand

Subject: [PATCH 018/521] fix(cz-cli): spec review fixes for ai-guide and
 install-skills

- ai-guide: add -f/--format option with toon default (was using global
  --output flag incorrectly)
- install-skills: add per-skill interactive selection when not using -y

Subject: [PATCH 019/521] refactor(opencode): rename to czcli, replace profile
 with cz-tool forwarding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Change scriptName and brand.name from "czagent" to "czcli"
- Replace built-in ProfileCommand with forward commands delegating to cz-tool
- Delete profile module (packages/opencode/src/profile/) — now handled by cz-tool
- Replace loadProfiles() middleware with spawnSync check against cz-tool
- Distinguish cz-tool-not-found from no-profiles in error messages
- Update all user-facing "czagent" strings to "czcli"
- Add @clickzetta/sdk workspace dependency
- Use Brand.name/Brand.display for scriptName and show() header

Subject: [PATCH 020/521] feat(opencode): register cz-tool as built-in tool for
 agent

Add cz_tool to the tool registry so the AI agent can execute ClickZetta
CLI commands (SQL, table/schema management, task scheduling) directly.
Spawns cz-tool through sh -c for proper shell quoting of SQL strings.

+Execute ClickZetta Lakehouse CLI commands via cz-tool. Use this tool for database operations including SQL queries, table management, schema operations, task scheduling, and profile management.
+
+Commands are passed as a single string and forwarded to the cz-tool binary. Output is always JSON for machine parsing.
+
+Common commands:
+- sql "SELECT * FROM table LIMIT 10" — execute SQL
+- table list — list tables
+- table describe <name> — describe table schema
+- schema list — list schemas
+- profile list — list connection profiles
+- task list — list scheduled tasks
+- runs list — list task run instances
+- status — check connection status
+
+The --output json flag is automatically appended. Use --profile <name> to target a specific connection profile.

Subject: [PATCH 022/521] fix: rename czagent references to czcli in config,
 setup, and skills
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- config.ts: look for czcli.json first, fall back to czagent.json
- setup.sh: fix variable names and header comment
- skills/czagent → skills/czcli directory rename

Subject: [PATCH 023/521] feat: complete cz-cli TypeScript rewrite with full
 Python parity

Comprehensive migration from Python cz-tool to TypeScript cz-cli:
- All CLI commands ported with logic parity (sql, task, runs, profile, etc.)
- Build pipeline unified: binary name "czcli", archive prefix "czcli-{platform}"
- Install/update pipeline: install.sh, setup.sh, auto-update.ts all consistent
- Skills packaging: cz-cli + lakehouse-doc bundled and installed to IDE agents
- SDK layer: clickzetta-sdk with direct REST for auth, SQL, Studio APIs
- Opencode agent: renamed to czcli, cz-tool registered as built-in tool

+## Features
 
-### Desktop App (BETA)
+- **Data Agent** — Natural-language Lakehouse operations, one-shot or conversational, powered by AI
+- **AI Subagent** — Auto-registers as a skill for Claude Code, Cursor, Codex, and Kiro so your AI coding assistant can operate on Lakehouse directly
+- **AI-Friendly Output** — JSON output by default, structured error messages with auto-correction hints
+- **SQL Execution** — Run queries directly, with async polling for long-running jobs
+- **Studio Task Scheduling** — Create, configure, publish, and monitor scheduled tasks and flows
+- **Rich Commands** — SQL, workspace, schema, table, task, runs, attempts, job, and profile management
 
-OpenCode is also available as a desktop application. Download directly from the [releases page](https://github.com/anomalyco/opencode/releases) or [opencode.ai/download](https://opencode.ai/download).
+## Quick Start
 
-| Platform              | Download                              |
-| --------------------- | ------------------------------------- |
-| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |
-| macOS (Intel)         | `opencode-desktop-darwin-x64.dmg`     |
-| Windows               | `opencode-desktop-windows-x64.exe`    |
-| Linux                 | `.deb`, `.rpm`, or AppImage           |
+### Configure
 
 ```bash
-# macOS (Homebrew)
-brew install --cask opencode-desktop
-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
+cz-cli setup
 ```
 
-#### Installation Directory
+Or with a registration token (non-interactive):
 
-The install script respects the following priority order for the installation path:
+```bash
+cz-cli setup --credential <base64_string>
+```
 
-1. `$OPENCODE_INSTALL_DIR` - Custom installation directory
-2. `$XDG_BIN_DIR` - XDG Base Directory Specification compliant path
-3. `$HOME/bin` - Standard user binary directory (if it exists or can be created)
-4. `$HOME/.opencode/bin` - Default fallback
+### Use
 
 ```bash
-# Examples
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
+cz-cli agent run "show row counts for all tables in my_schema"
+
+cz-cli sql "SELECT * FROM my_schema.my_table LIMIT 10"
+
+cz-cli status
 ```
 
-### Agents
+## Commands
 
-OpenCode includes two built-in agents you can switch between with the `Tab` key.
+```bash
+cz-cli <command> [options]
+```
 
-- **build** - Default, full-access agent for development work
-- **plan** - Read-only agent for analysis and code exploration
-  - Denies file edits by default
-  - Asks permission before running bash commands
-  - Ideal for exploring unfamiliar codebases or planning changes
+| Command | Description |
+| --- | --- |
+| `agent run "<prompt>"` | Run AI agent with a natural-language prompt |
+| `sql "<query>"` | Execute a SQL query |
+| `table list` | List tables |
+| `schema list` | List schemas |
+| `task list` | List Studio tasks |
+| `runs list` | View task run history |
+| `job <job_id>` | Inspect job execution details |
+| `profile list` | Manage connection profiles |
+| `setup` | Interactive configuration wizard |
 
-Also included is a **general** subagent for complex searches and multistep tasks.
-This is used internally and can be invoked using `@general` in messages.
+### Agent Sessions
 
-Learn more about [agents](https://opencode.ai/docs/agents).
+```bash
+# One-shot (scripts, CI)
+cz-cli agent run "create a daily sync task"
 
-### Documentation
+# Conversational (reuse context with --session)
+cz-cli agent run "describe the sales table" --session my-session
+cz-cli agent run "add a region column to sales" --session my-session
+```
 
-For more info on how to configure OpenCode, [**head over to our docs**](https://opencode.ai/docs).
+### AI Subagent Invocation
 
-### Contributing
+AI agents call cz-cli with structured output via the `--format a2a` flag:
 
-If you're interested in contributing to OpenCode, please read our [contributing docs](./CONTRIBUTING.md) before submitting a pull request.
+```bash
+cz-cli agent run "<request>" --format a2a --dangerously-skip-permissions
+```
+
+Use `--session <id>` for multi-turn conversations on the same topic.
+
+## Installation Options
+
+### Manual Install
+
+Download the archive for your platform from [Releases](https://github.com/clickzetta/cz-cli/releases), extract, and run:
 
-### Building on OpenCode
+```bash
+sh setup.sh
+```
+
+### Pin a Version
 
-If you are working on a project that's related to OpenCode and is using "opencode" as part of its name, for example "opencode-dashboard" or "opencode-mobile", please add a note to your README to clarify that it is not built by the OpenCode team and is not affiliated with us in any way.
+```bash
+CZ_VERSION=0.1.0 curl -fsSL https://github.com/clickzetta/cz-cli/releases/latest/download/install.sh | sh
+```
 
-### FAQ
+### Environment Variables
 
-#### How is this different from Claude Code?
+| Variable | Description |
+| --- | --- |
+| `CZ_VERSION` | Pin a specific version (e.g. `0.1.0`) |
+| `CZ_MIRROR` | Custom mirror base URL for downloads |
+| `NON_INTERACTIVE` | Skip all interactive prompts |
 
-It's very similar to Claude Code in terms of capability. Here are the key differences:
+### Supported Platforms
 
-- 100% open source
-- Not coupled to any provider. Although we recommend the models we provide through [OpenCode Zen](https://opencode.ai/zen), OpenCode can be used with Claude, OpenAI, Google, or even local models. As models evolve, the gaps between them will close and pricing will drop, so being provider-agnostic is important.
-- Out-of-the-box LSP support
-- A focus on TUI. OpenCode is built by neovim users and the creators of [terminal.shop](https://terminal.shop); we are going to push the limits of what's possible in the terminal.
-- A client/server architecture. This, for example, can allow OpenCode to run on your computer while you drive it remotely from a mobile app, meaning that the TUI frontend is just one of the possible clients.
+| Platform | Architecture |
+| --- | --- |
+| Linux | x64, arm64 |
+| macOS | arm64 (Apple Silicon) |
+| Windows | x64, arm64 |

+# cz-cli Skill
+
+> [!IMPORTANT]
+> **Fallback**: If `cz-cli` command not present, check for a bundled binary at `scripts/<platform>/cz-cli` (e.g. `scripts/macos-arm64/cz-cli`, `scripts/linux-x86_64/cz-cli`, `scripts/windows-x86_64/cz-cli.exe`). If found, use its absolute path directly. Otherwise run `pip3 install cz-cli -U` then use `cz-cli` from PATH.
+
+## AI Agent Behavior Rules
+
+> [!IMPORTANT]
+> Read these rules before invoking any command.
+
+### Rule 0 — Initialize connection profile before first use
+
+When any command returns error code `NO_PROFILE`, run `cz-cli setup --credential <base64>` if the credential string is available, or read `references/profile-setup.md` and follow the onboarding steps there. Always use the **AskUserQuestion tool** — never ask via plain text.
+
+### Rule 1 — Clarify intent before any state-changing operation
+
+When a task involves an operation that changes system state (publishing a schedule, taking a task offline, triggering a run, deleting an object, etc.):
+
+**Do NOT proceed without** explicitly understanding the user's intent on all three points:
+1. **Target**: Which task / table / run instance?
+2. **Purpose**: Why does this need to happen now?
+3. **Side-effect acknowledgment**: Does the user understand the impact (historical re-runs, schedule interruption, permanent deletion, etc.)?
+
+Use the **AskUserQuestion tool** (not plain text) to confirm with the user, then wait for an explicit reply before executing.
+
+Consult **Command Risk Reference** below to determine whether a command qualifies as state-changing.
+
+
+### Rule 2 — Route to companion skill BEFORE acting (MUST)
+
+> [!IMPORTANT]
+> Check this routing table **before** executing any command or writing any code.
+> If the user intent matches a trigger below, **MUST** invoke the listed skill immediately and stop processing in cz-cli.
+
+The following companion skills can be installed alongside `cz-cli` via `cz-cli install-skills`:
+
+- **lakehouse-python-sdk** — Lakehouse Python/Shell task engineering: develop, rewrite, optimize, troubleshoot. Covers connector, BulkLoad, IGS, Studio params, datasource, and CREATE TABLE DDL; MUST trigger on: develop/write/create/modify/rewrite/optimize Python or Shell task; BulkLoad batch upload; IGS realtime ingest; connector query/write; Python task error/diagnosis; CREATE TABLE / partition / bucket / index DDL.
+- **lakehouse-doc** — ClickZetta Lakehouse official documentation. Covers SQL syntax, data types, functions, DDL/DML commands, dynamic tables, materialized views, access control, VCluster, data lake, AI functions, etc. When the user writes or asks about SQL syntax or Lakehouse dialect specifics, **MUST** consult lakehouse-doc skill references first to ensure accuracy.
+
+**If no row matches**: proceed with cz-cli commands directly.
+
+### Rule 2.1 — MUST consult lakehouse-doc skill for SQL commands
+
+When the user request involves any of the following, **MUST** consult **lakehouse-doc** skill references before answering or generating SQL:
+
+- Writing, modifying, or optimizing SQL statements (DDL / DML / DQL)
+- Asking about ClickZetta Lakehouse SQL dialect syntax, keywords, or function usage
+- Using data types, type casting, or datetime formats
+- Creating or altering tables, views, materialized views, dynamic tables, external tables
+- Data import/export (COPY INTO, PUT/GET, BulkLoad, Pipe)
+- Access control (GRANT / REVOKE), roles, permissions
+- VCluster configuration and management
+- Index creation and usage (inverted index, BloomFilter, vector index)
+- AI functions, vector search, semantic views
+- Information Schema system view queries
+
+**Rationale**: ClickZetta Lakehouse SQL dialect differs from standard SQL and other databases. Relying on general knowledge may produce incorrect syntax. Consulting lakehouse-doc significantly improves answer accuracy and confidence.
+
+### Rule 3 — Development ends at save; execution requires separate authorization
+
+When the user says "develop", "write", "create", or "modify" a task, the work is **complete once the script is saved successfully**.
+After saving, tell the user: "The task has been saved as a draft. Scheduling is not yet active. Let me know explicitly if you want to publish or execute it."
+
+**Do NOT** auto-publish, auto-trigger execution, or auto-submit a backfill after saving — even if those steps seem like the logical next thing. Every phase that produces a real side effect requires the user to express intent and grant authorization separately.
+
+**Exception**: If the user's original request *explicitly* authorized all subsequent steps (e.g. "create and immediately go live", "develop and run it now"), AND Rule 1 already confirmed that intent at the start, the Agent may proceed through the authorized steps without stopping again at each phase. Do not re-ask for confirmation that was already given.
+
+### Rule 4 — Paginated results are not complete data
+
+All `list` commands return only page 1 by default (typically 10 items). The `ai_message` field in the response contains the total count and the command to fetch the next page — treat it as the authoritative next-step hint and follow it. Never treat a first-page result as the full dataset.
+
+**Pagination termination rules**:
+- If the user only needs "latest / recent N items": stop after page 1, do not paginate.
+- If the user needs the full dataset: paginate until `ai_message` no longer contains a next-page hint.
+- **Safety limit**: auto-paginate at most **3 pages** (≈ 30 items). If more exist, surface the next-page command to the user and ask whether to continue.
+
+### Rule 5 — Always pass explicit task type when creating tasks
+
+When creating a task with `cz-cli task create`, **always** pass `--type` explicitly (`SQL` / `PYTHON` / `SHELL` / `SPARK` / `FLOW`).
+The Python SDK(connector/igs/bulkload) is using from clickzetta import connect instead of Zettapark's session.
+
+- **MUST NOT** rely on default task type.
+- If user intent says “Python task”, command must include `--type PYTHON`.
+- If `--type FLOW`, immediately switch to Rule 6 — use Flow-specific commands exclusively.
+
+### Rule 6 — Flow nodes use Flow-specific tools exclusively
+
+When the operation target is a Flow task or any of its child nodes (`task_type=500`, or user mentions "composite task / flow / workflow"):
+
+- **MUST** use Flow-specific commands: `task flow node-detail`, `task flow node-save`, `task flow node-save-config`, `task flow bind`, `task flow submit`, etc.
+- **MUST NOT** use `task save`, `task save-config`, `task detail`, or `task online` on Flow child nodes — these tools are for regular (non-Flow) tasks only and will produce incorrect results or errors.
+- **Decision rule**: if `task_type == 500` OR the user mentions flow/workflow context → use `task flow *` commands unconditionally.
+
+### Rule 7 — Always display studio_url in final report
+
+Responses from `task`, `runs`, and `executions` commands may include a `studio_url` field. When present, surface it in the end to the user so they can open the resource directly in Studio.
+
+Display as a Markdown hyperlink: `[View in Studio](https://...)`. Show all studio_url values returned across all commands in the same response — do not deduplicate.
+
+### Rule 8 — Maximize execution efficiency: parallel and chained commands
+
+**Independent commands → parallel.  Dependent commands → chain with `--field`.**
+
+```bash
+# Async SQL: submit → poll → fetch result → preview first rows
+JOB=$(cz-cli sql "SELECT * FROM orders LIMIT 100" --field job_id) && cz-cli job status $JOB -o toon && cz-cli job result $JOB -o toon | head -12
+
+# Parallel: two independent lookups at the same time
+cz-cli task content my_task -o toon & cz-cli runs list --task my_task -o toon & wait
+
+# Chain: save then verify
+cz-cli task save-content my_task --file script.sql && cz-cli task content my_task -o toon
+```
+
+Key tools:
+- `--field <name>` — extract one value as raw text: `cz-cli sql "..." --field job_id` → `2026042818122957849079780`
+- `-o toon` — line-per-field output, works with `grep`/`head`
+- `-o json` — single-line JSON, parse in code only (do NOT pipe to grep/head)
+
+**Shortcut**: Use `cz-cli sql --sync "..." > /tmp/res.json` to force synchronous execution (waits for results inline). Prefer `--sync` for simple/fast queries.

+# cz-cli Skill
+
+> [!IMPORTANT]
+> **Fallback**: If `cz-cli` command not present, check for a bundled binary at `scripts/<platform>/cz-cli` (e.g. `scripts/macos-arm64/cz-cli`, `scripts/linux-x86_64/cz-cli`, `scripts/windows-x86_64/cz-cli.exe`). If found, use its absolute path directly. Otherwise run `pip3 install cz-cli -U` then use `cz-cli` from PATH.
+
+## AI Agent Behavior Rules
+
+> [!IMPORTANT]
+> Read these rules before invoking any command.
+
+### Rule 0 — Initialize connection profile before first use
+
+When any command returns error code `NO_PROFILE`, run `cz-cli setup --credential <base64>` if the credential string is available, or read `references/profile-setup.md` and follow the onboarding steps there. Always use the **AskUserQuestion tool** — never ask via plain text.
+
+### Rule 1 — Clarify intent before any state-changing operation
+
+When a task involves an operation that changes system state (publishing a schedule, taking a task offline, triggering a run, deleting an object, etc.):
+
+**Do NOT proceed without** explicitly understanding the user's intent on all three points:
+1. **Target**: Which task / table / run instance?
+2. **Purpose**: Why does this need to happen now?
+3. **Side-effect acknowledgment**: Does the user understand the impact (historical re-runs, schedule interruption, permanent deletion, etc.)?
+
+Use the **AskUserQuestion tool** (not plain text) to confirm with the user, then wait for an explicit reply before executing.
+
+Consult **Command Risk Reference** below to determine whether a command qualifies as state-changing.
+
+
+### Rule 2 — Route to companion skill BEFORE acting (MUST)
+
+> [!IMPORTANT]
+> Check this routing table **before** executing any command or writing any code.
+> If the user intent matches a trigger below, **MUST** invoke the listed skill immediately and stop processing in cz-cli.
+
+The following companion skills can be installed alongside `cz-cli` via `cz-cli install-skills`:
+
+- **lakehouse-python-sdk** — Lakehouse Python/Shell task engineering: develop, rewrite, optimize, troubleshoot. Covers connector, BulkLoad, IGS, Studio params, datasource, and CREATE TABLE DDL; MUST trigger on: develop/write/create/modify/rewrite/optimize Python or Shell task; BulkLoad batch upload; IGS realtime ingest; connector query/write; Python task error/diagnosis; CREATE TABLE / partition / bucket / index DDL.
+- **lakehouse-doc** — ClickZetta Lakehouse official documentation. Covers SQL syntax, data types, functions, DDL/DML commands, dynamic tables, materialized views, access control, VCluster, data lake, AI functions, etc. When the user writes or asks about SQL syntax or Lakehouse dialect specifics, **MUST** consult lakehouse-doc skill references first to ensure accuracy.
+
+**If no row matches**: proceed with cz-cli commands directly.
+
+### Rule 2.1 — MUST consult lakehouse-doc skill for SQL commands
+
+When the user request involves any of the following, **MUST** consult **lakehouse-doc** skill references before answering or generating SQL:
+
+- Writing, modifying, or optimizing SQL statements (DDL / DML / DQL)
+- Asking about ClickZetta Lakehouse SQL dialect syntax, keywords, or function usage
+- Using data types, type casting, or datetime formats
+- Creating or altering tables, views, materialized views, dynamic tables, external tables
+- Data import/export (COPY INTO, PUT/GET, BulkLoad, Pipe)
+- Access control (GRANT / REVOKE), roles, permissions
+- VCluster configuration and management
+- Index creation and usage (inverted index, BloomFilter, vector index)
+- AI functions, vector search, semantic views
+- Information Schema system view queries
+
+**Rationale**: ClickZetta Lakehouse SQL dialect differs from standard SQL and other databases. Relying on general knowledge may produce incorrect syntax. Consulting lakehouse-doc significantly improves answer accuracy and confidence.
+
+### Rule 3 — Development ends at save; execution requires separate authorization
+
+When the user says "develop", "write", "create", or "modify" a task, the work is **complete once the script is saved successfully**.
+After saving, tell the user: "The task has been saved as a draft. Scheduling is not yet active. Let me know explicitly if you want to publish or execute it."
+
+**Do NOT** auto-publish, auto-trigger execution, or auto-submit a backfill after saving — even if those steps seem like the logical next thing. Every phase that produces a real side effect requires the user to express intent and grant authorization separately.
+
+**Exception**: If the user's original request *explicitly* authorized all subsequent steps (e.g. "create and immediately go live", "develop and run it now"), AND Rule 1 already confirmed that intent at the start, the Agent may proceed through the authorized steps without stopping again at each phase. Do not re-ask for confirmation that was already given.
+
+### Rule 4 — Paginated results are not complete data
+
+All `list` commands return only page 1 by default (typically 10 items). The `ai_message` field in the response contains the total count and the command to fetch the next page — treat it as the authoritative next-step hint and follow it. Never treat a first-page result as the full dataset.
+
+**Pagination termination rules**:
+- If the user only needs "latest / recent N items": stop after page 1, do not paginate.
+- If the user needs the full dataset: paginate until `ai_message` no longer contains a next-page hint.
+- **Safety limit**: auto-paginate at most **3 pages** (≈ 30 items). If more exist, surface the next-page command to the user and ask whether to continue.
+
+### Rule 5 — Always pass explicit task type when creating tasks
+
+When creating a task with `cz-cli task create`, **always** pass `--type` explicitly (`SQL` / `PYTHON` / `SHELL` / `SPARK` / `FLOW`).
+The Python SDK(connector/igs/bulkload) is using from clickzetta import connect instead of Zettapark's session.
+
+- **MUST NOT** rely on default task type.
+- If user intent says “Python task”, command must include `--type PYTHON`.
+- If `--type FLOW`, immediately switch to Rule 6 — use Flow-specific commands exclusively.
+
+### Rule 6 — Flow nodes use Flow-specific tools exclusively
+
+When the operation target is a Flow task or any of its child nodes (`task_type=500`, or user mentions "composite task / flow / workflow"):
+
+- **MUST** use Flow-specific commands: `task flow node-detail`, `task flow node-save`, `task flow node-save-config`, `task flow bind`, `task flow submit`, etc.
+- **MUST NOT** use `task save`, `task save-config`, `task detail`, or `task online` on Flow child nodes — these tools are for regular (non-Flow) tasks only and will produce incorrect results or errors.
+- **Decision rule**: if `task_type == 500` OR the user mentions flow/workflow context → use `task flow *` commands unconditionally.
+
+### Rule 7 — Always display studio_url in final report
+
+Responses from `task`, `runs`, and `executions` commands may include a `studio_url` field. When present, surface it in the end to the user so they can open the resource directly in Studio.
+
+Display as a Markdown hyperlink: `[View in Studio](https://...)`. Show all studio_url values returned across all commands in the same response — do not deduplicate.
+
+### Rule 8 — Maximize execution efficiency: parallel and chained commands
+
+**Independent commands → parallel.  Dependent commands → chain with `--field`.**
+
+```bash
+# Async SQL: submit → poll → fetch result → preview first rows
+JOB=$(cz-cli sql "SELECT * FROM orders LIMIT 100" --field job_id) && cz-cli job status $JOB -o toon && cz-cli job result $JOB -o toon | head -12
+
+# Parallel: two independent lookups at the same time
+cz-cli task content my_task -o toon & cz-cli runs list --task my_task -o toon & wait
+
+# Chain: save then verify
+cz-cli task save-content my_task --file script.sql && cz-cli task content my_task -o toon
+```
+
+Key tools:
+- `--field <name>` — extract one value as raw text: `cz-cli sql "..." --field job_id` → `2026042818122957849079780`
+- `-o toon` — line-per-field output, works with `grep`/`head`
+- `-o json` — single-line JSON, parse in code only (do NOT pipe to grep/head)
+
+**Shortcut**: Use `cz-cli sql --sync "..." > /tmp/res.json` to force synchronous execution (waits for results inline). Prefer `--sync` for simple/fast queries.

+# Profile Setup — Connection Onboarding Guide
+
+Use this reference when any command returns error code `NO_PROFILE`.
+
+## Preferred: `cz-cli setup`
+
+The recommended first-time onboarding entry point is `cz-cli setup`:
+
+```
+cz-cli setup --credential "<base64_string>"
+```
+
+Or without `--credential` in an interactive terminal to launch the guided flow:
+
+```
+cz-cli setup
+```
+
+The main CLI process **does not** automatically launch an interactive quickstart flow.
+Instead, when no profile exists, data commands (e.g. `sql`, `table list`) output a
+structured `NO_PROFILE` error and exit. The AI agent should then guide the user to
+run `cz-cli setup`.
+
+## Non-Interactive / Scripted Setup
+
+For AI agents or automation (non-TTY environments), always pass `--credential`:
+
+```
+cz-cli setup --credential "<base64_string>"
+```
+
+Or use the equivalent `profile quickstart` subcommand (backward compatible):
+
+```
+cz-cli profile quickstart --credential "<base64_string>"
+```
+
+Without `--credential`, both commands output registration URLs as JSON:
+
+```
+cz-cli setup
+cz-cli profile quickstart
+```
+
+## Alternative: Choose auth method (advanced)
+
+If the user prefers manual setup, use the **AskUserQuestion tool**. Present three options:
+
+## Step 2 — Collect credentials (branch by choice)
+
+### Branch A — JDBC URL (user already has one)
+
+1. Ask: "Please paste your JDBC URL (format: `jdbc:clickzetta://...`)."
+2. If the URL contains the literal placeholder `<password>`, ask for the real password separately and substitute it before use.
+3. Derive a profile name from the URL (e.g. `default`) or ask the user.
+4. Run:
+   ```
+   cz-cli profile create <name> --jdbc "<url_with_real_password>"
+   ```
+
+### Branch A — JDBC URL (guided copy-from-Studio flow)
+
+If the user doesn't have a JDBC URL, guide them to copy one from Studio:
+
+1. Ask: "What is your Studio page URL?"
+2. Do not ask user to identify URL type. Accept any Studio URL directly.
+   Examples:
+   - `https://rwyaytab.accounts.clickzetta.com/accountManage/accountInfo`
+   - `https://czstudio.devops.xiaohongshu.com/accounts/wuhsuxis/login`
+   - `https://studio-bj-gaotu.clickzetta-inc.com/app/14743d05`
+3. Reply with the exact link to open:
+   ```
+   <studio_url>/management/environment
+   ```
+   Then prompt: "Navigate to **工作空间 → 连接配置 → 复制**. This copies a JDBC URL that may contain `<password>` as a placeholder."
+4. Ask the user to paste the copied URL, then handle the `<password>` placeholder as above.
+
+### Branch B — PAT
+
+1. Ask for: PAT value, instance name, workspace name (optionally: default schema, vcluster).
+2. Run:
+   ```
+   cz-cli profile create <name> --pat <PAT> --instance <instance name> --workspace <WS>
+   ```
+
+### Branch C — Username / Password (recommended discovery flow)
+
+1. Ask for:
+   - username
+   - password
+   - Studio page URL
+2. Run the built-in discover command to authenticate and discover regions + instances:
+   ```
+   cz-cli profile discover \
+     --studio-url "<studio_url>" \
+     --username "<username>" \
+     --password "<password>"
+   ```
+   The command auto-detects URL type; user does not need to distinguish account URL vs app URL.
+3. Ask user to choose region, then list workspaces in that region:
+   ```
+   cz-cli profile list-workspaces \
+     --studio-url "<studio_url>" \
+     --username "<username>" \
+     --password "<password>" \
+     --region "<region_id_or_alias>" \
+     --instance "<optional_instance_name>"
+   ```
+4. Generate a safe `profile create` command (default schema/vcluster included):
+   ```
+   cz-cli profile render-command \
+     --studio-url "<studio_url>" \
+     --username "<username>" \
+     --password "<password>" \
+     --region "<region_id_or_alias>" \
+     --instance "<instance_name>" \
+     --workspace "<workspace_name>" \
+     --profile-name "<profile_name>"
+   ```
+5. Execute the generated command.
+
+Important:
+- Never map tenant/account ID to `--instance`.
+- `--instance` must be a real Studio instance name.
+- Defaults are `--schema public` and `--vcluster default`.
+
+Manual fallback if all fields are already known:
+```
+cz-cli profile create <name> \
+  --username <U> \
+  --password <P> \
+  --instance <instance_name> \
+  --workspace <workspace_name> \
+  --service <service_host> \
+  --schema public \
+  --vcluster default
+```
+
+## Step 3 — Verify and proceed
+
+- Check `exit_code=0` and `ok=true` in JSON output.
+- On success, proceed with the original request using `--profile <name>`.
+- On failure, show the error and ask the user to re-check credentials.

-# czagent — ClickZetta Lakehouse Subagent
-
-czagent is the ONLY way to interact with ClickZetta Lakehouse. You do not have direct access to Lakehouse. Always delegate to czagent — never try to run cz-cli, write SQL yourself, or guess at Lakehouse behavior.
-
-## Routing Rules
-
-**MUST send to czagent (no exceptions):**
-- Any SQL query against ClickZetta Lakehouse (SELECT, DDL, DML)
-- Studio task development, scheduling, and monitoring
-- Table/schema/database management on Lakehouse
-- Data pipeline operations (sync, import, CDC)
-- ClickZetta profile and connection configuration
-- Lakehouse performance analysis and optimization
-- Any request that mentions czagent, ClickZetta, or Lakehouse
-
-**Keep in the host agent:**
-- General programming (Python, TypeScript, etc.) unrelated to ClickZetta
-- Local file system operations
-- Git operations
-- Non-ClickZetta database work (PostgreSQL, MySQL as standalone)
-- Questions about the host agent itself
-
-## Execution
-
-Run czagent headless via the bundled script:
-
-```bash
-python3 <skill_dir>/scripts/execute_czagent.py --prompt "user's request here"
-```
-
-For follow-up queries on the same Lakehouse task, pass the session ID returned from the previous call:
-
-```bash
-python3 <skill_dir>/scripts/execute_czagent.py --prompt "follow-up request" --session <session_id>
-```
-
-`<skill_dir>` is the directory containing this SKILL.md file.
-
-## Session Management
-
-- czagent returns a `session_id` in its output. Store it for the duration of the conversation.
-- Reuse the same session for follow-up questions on the same Lakehouse topic — this preserves context (connection state, query history, table metadata).
-- Start a new session (omit `--session`) when the user switches to a different Lakehouse topic or explicitly asks to start fresh.
-
-## Result Handling
-
-The script outputs JSON to stdout:
-
-```json
-{
-  "session_id": "abc123",
-  "result": "czagent's response text",
-  "cost": { "input_tokens": 1234, "output_tokens": 567 }
-}
-```
-
-- Present `result` to the user as-is. Do not re-summarize unless the user asks.
-- If the result contains SQL output or tables, preserve formatting.
-- If czagent reports an error, relay it and suggest the user check their ClickZetta profile (`czagent profile`).
-
-## Fast Path
-
-For simple follow-ups ("show me the next 10 rows", "run that again with WHERE clause"), execute immediately with the existing session. No need to re-confirm routing or re-explain what czagent is.

+cz-cli install-skills
+```
+
+This skill enables your coding agent to delegate software development tasks to czcode -- ClickZetta's AI coding assistant -- running headlessly in the background, with full security controls and audit logging.
+
+## Architecture Overview
+
+**Routing Principle**: Coding and development tasks -> czcode. Lakehouse operations -> cz-cli.
+
+**Key Components**:
+- `scripts/route_request.py` -- LLM-based semantic routing with credential blocking
+- `scripts/execute_czcode.py` -- Headless czcode execution with NDJSON stream parsing and heartbeat
+- `scripts/security_wrapper.py` -- Full security orchestration (approval, audit, sanitization)
+- `scripts/read_czcode_sessions.py` -- Recent session context enrichment
+- `security/` -- Approval handler, audit logger, cache manager, config manager, prompt sanitizer
+
+**Security Modes**:
+- `prompt` (default): User approves predicted tools before execution
+- `auto`: Auto-approve with mandatory audit logging
+- `envelope_only`: Auto-approve, rely on envelope blocklist only
+
+> **IMPORTANT -- `config.yaml` is optional.** If absent, safe defaults apply (`approval_mode: prompt`). Do NOT search for `config.yaml` before executing -- `ConfigManager` handles this internally.
+
+## Fast Path for Repeat Queries
+
+**Session state is cached -- skip re-initialization on follow-up queries.**
+
+For a follow-up coding request in the same session:
+1. Skip context re-fetch (reuse Lakehouse context from first query)
+2. Call `execute_czcode.py` directly with the enriched prompt
+3. Return results
+
+## Session Initialization
+
+When this skill is first loaded in a session:
+
+### Step 1: Load Routing Context
+```bash
+PYTHON=$(command -v python3 2>/dev/null || echo python3)
+$PYTHON scripts/route_request.py --prompt "test" --dry-run 2>/dev/null || true
+```
+This warms up the config and cache. Skip on follow-up queries.
+
+## Workflow: Handling User Requests
+
+### Step 1: Route the Request
+
+```bash
+PYTHON=$(command -v python3 2>/dev/null || echo python3)
+$PYTHON scripts/route_request.py --prompt "USER_PROMPT_HERE"
+```
+
+**Route to czcode** if request involves:
+- Writing, creating, or modifying code (Python, SQL scripts, Shell, etc.)
+- Debugging, fixing errors, or diagnosing code issues
+- Refactoring or optimizing existing code
+- Explaining or reviewing code
+- Developing Studio task bodies (Python/Shell)
+- General programming questions or best practices
+- User explicitly mentions "czcode"
+
+**Handle locally with cz-cli** if request involves:
+- Executing SQL on ClickZetta Lakehouse (`cz-cli sql`)
+- Managing Studio tasks (create, schedule, online/offline)
+- Table or schema operations
+- Profile/connection configuration
+- Checking run status or execution logs
+
+If routing returns `cz_cli`: handle with cz-cli commands directly. Stop here.
+
+### Step 2: Enrich Context
+
+Build an enriched prompt with Lakehouse context and recent session history:
+
+**Lakehouse Context** (if a cz-cli profile is active):
+```bash
+cz-cli profile list -o json 2>/dev/null | python3 -c "
+import sys, json
+profiles = json.load(sys.stdin).get('data', [])
+if profiles:
+    p = profiles[0]
+    print(f'ClickZetta Lakehouse: instance={p.get(\"instance\",\"\")}, workspace={p.get(\"workspace\",\"\")}, schema={p.get(\"schema\",\"\")}')" 2>/dev/null
+```
+
+**Recent czcode Session Context** (optional, for follow-up tasks):
+```bash
+PYTHON=$(command -v python3 2>/dev/null || echo python3)
+$PYTHON scripts/read_czcode_sessions.py --limit 2
+```
+
+**Enriched Prompt Format**:
+```
+# Lakehouse Context
+[Connection info if relevant to the task]
+
+# Recent czcode Work
+[Summary from recent czcode sessions, if relevant]
+
+# User Request
+[Original user prompt]
+```
+
+### Step 3: Handle Security Approval
+
+```bash
+PYTHON=$(command -v python3 2>/dev/null || echo python3)
+$PYTHON scripts/security_wrapper.py \
+  --prompt "ENRICHED_PROMPT" \
+  --envelope "RW"
+```
+
+- If `status: awaiting_approval` -> show `approval_prompt` to user, wait for response
+- If `status: routed_to_cz_cli` -> handle with cz-cli directly
+- If `status: blocked` -> inform user, do not proceed
+- If `status: executed` or `approval_mode: auto/envelope_only` -> proceed to Step 4
+
+### Step 4: Execute czcode Headlessly
+
+```bash
+PYTHON=$(command -v python3 2>/dev/null || echo python3)
+$PYTHON scripts/execute_czcode.py \
+  --prompt "ENRICHED_PROMPT" \
+  --envelope "RW" \
+  --approval-mode auto
+```
+
+With Lakehouse context injection:
+```bash
+$PYTHON scripts/execute_czcode.py \
+  --prompt "ENRICHED_PROMPT" \
+  --envelope "RW" \
+  --approval-mode auto \
+  --system-prompt "ClickZetta Lakehouse: instance=INSTANCE, workspace=WORKSPACE, schema=SCHEMA"
+```
+
+**Key flags**:
+- `--permission-mode bypass` is set internally -- headless auto-approval
+- `--output-format stream-json` -- NDJSON event stream, parsed in real-time
+- Heartbeat thread prevents AI tool timeouts during long-running tasks
+
+**Security Envelopes**:
+- **RO**: Blocks Edit, Write, destructive Bash -- for read-only tasks
+- **RW**: Blocks only destructive ops (rm -rf, sudo rm) -- for most coding tasks
+- **RESEARCH**: Read + web access, blocks writes -- for exploratory work
+- **DEPLOY**: Full access -- use cautiously, requires confirmation
+
+### Step 5: Return Results
+
+- Display czcode's text output to the user
+- Report any files created or modified
+- If czcode wrote code to be saved as a Studio task: suggest `cz-cli task save`
+
+## Examples
+
+### Example 1: Develop a Python Studio Task
+**User says**: "Write a Python task that reads from table `orders` and writes aggregated results to `orders_summary`"
+
+**Routing**: -> czcode
+
+**Execute**:
+```bash
+$PYTHON scripts/execute_czcode.py \
+  --prompt "Write a Python task that reads from ClickZetta table 'orders' and writes aggregated results to 'orders_summary'. Use the clickzetta connector." \
+  --envelope "RW" \
+  --system-prompt "ClickZetta Lakehouse: instance=my-instance, workspace=default, schema=public"
+```
+
+**Result**: Python task code returned -> save via `cz-cli task save`.
+
+### Example 2: Debug a Failing Task
+**User says**: "My Python task is throwing a KeyError on line 42"
+
+**Routing**: -> czcode (debugging)
+
+**Envelope**: RO (read-only -- just diagnosing)
+
+### Example 3: Execute SQL on Lakehouse
+**User says**: "Run `SELECT COUNT(*) FROM orders`"
+
+**Routing**: -> cz-cli
+
+```bash
+cz-cli sql "SELECT COUNT(*) FROM orders"
+```
+
+No czcode involvement.
+
+### Example 4: Code Review
+**User says**: "Review this Python script for bugs"
+
+**Routing**: -> czcode
+
+**Envelope**: RO (read-only review)
+
+## Troubleshooting
+
+### Error: "czcode: command not found"
+```bash
+which czcode || ls ~/.local/bin/czcode
+# Fallback: use absolute path
+~/.local/bin/czcode --print "..." --permission-mode bypass
+```
+
+### Error: "ANTHROPIC_API_KEY not set"
+```bash
+export ANTHROPIC_API_KEY=your_key_here
+# Or check: cat ~/.clickzetta/czcode.json
+```
+
+### Issue: czcode hangs without output
+**Cause**: Not using `--print` flag in non-TTY environment.
+**Solution**: Always use `execute_czcode.py` -- never invoke `czcode` directly without `--print`.
+
+### Issue: Approval prompts not appearing
+```bash
+# Check approval mode
+cat "$(dirname $(which czcode))/../skills/czcode/config.yaml" 2>/dev/null | grep approval_mode
+# Default is "prompt" -- shows approval prompts
+```
+
+### Issue: Audit log not created
+```bash
+# Ensure log directory exists
+mkdir -p ~/.cache/czcode-skill
+chmod 700 ~/.cache/czcode-skill
+```
+
+### Issue: Output too verbose
+Use `--output-format text` in `execute_czcode.py` for plain text when stream parsing isn't needed.
+
+## Configuration
+
+Copy `config.yaml.example` to `config.yaml` in the skill's install directory to customize:
+- `approval_mode`: prompt / auto / envelope_only
+- `audit_log_path`: where to write audit logs
+- `sanitize_conversation_history`: enable/disable PII removal
+- `credential_file_allowlist`: paths that block routing when mentioned in prompts
+
+## References
+
+- czcode source: `~/code/cz-code`
+- czcode config: `~/.clickzetta/czcode.json`
+- Audit log: `~/.cache/czcode-skill/audit.log` (default)
+- Cache: `~/.cache/czcode-skill/`
+- cz-cli skill: install via `cz-cli install-skills`

+## 3. **云器lakehouse中导入飞书数据**
+
+### 方式一：使用python脚本导入飞书数据
+
+#### 步骤1：在云器Studio中创建Python任务
+
+1. 登录云器Lakehouse控制台
+2. 进入"开发" → "Python任务"
+3. 点击"新建任务"
+4. 配置任务信息：**任务名称**：飞书数据同步，**任务描述**：从飞书表格导入数据到Lakehouse
+
+#### 步骤2：配置代码参数
+
+```py
+import requests
+from sqlalchemy import text
+from clickzetta_dbutils import get_active_lakehouse_engine
+
+def get_feishu_token():
+    url = "https://open.feishu.cn/open-apis/auth/v3/tenant_access_token/internal"
+    data = {"app_id": "您自己的app_id", "app_secret": "xxxxxxxxxxxxx"}
+    response = requests.post(url, json=data, timeout=5)
+    return response.json()['tenant_access_token']
+
+def get_sheet_data(token):
+    url = "https://open.feishu.cn/open-apis/sheets/v2/spreadsheets/DuUHsqS6qh97i9tpNkYcoC84nHb/values/2729cf!A1:B2"
+    headers = {"Authorization": f"Bearer {token}"}
+    response = requests.get(url, headers=headers, timeout=5)
+    return response.json()['data']['valueRange']['values']
+
+def get_lakehouse_connection():
+    """
+    使用get_active_lakehouse_engine连接Lakehouse，无需用户在python中填写云器关联的账户信息
+    注意：vcluster参数是必填的
+    """
+    engine = get_active_lakehouse_engine(
+        vcluster="DEFAULT",  # 必填：虚拟集群名称
+        workspace="对应的工作空间名称",  # 可选：工作空间名称
+        schema="public"  # 可选：schema名称，默认为public
+    )
+    return engine
+
+def create_table():
+    """创建表：这里需要要求自己根据飞书表中的数据信息创建规范的table"""
+    engine = get_lakehouse_connection()
+    
+    create_sql = text("""

+        name VARCHAR(255),
+        id BIGINT,
+        created_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+    )
+    """)
+    
+    with engine.connect() as conn:
+        conn.execute(create_sql)
+    
+    print("✅ 表创建成功")
+
+def insert_data(data):
+    """插入数据 """

+        
+        with engine.connect() as conn:
+            insert_sql = f"INSERT INTO feishu_data (name, id) VALUES ('{name}', {id_value})"

+        rows = result.fetchall()
+        
+        print(f"\n📊 验证结果 (共{len(rows)}条记录):")
+        for row in rows:
+            print(f"  name: {row.name}, ID: {row.id}, 时间: {row.created_time}")
+
+if __name__ == "__main__":
+    print("🚀 飞书数据导入云器Lakehouse")
+    print("=" * 50)
+    
+    # 1. 获取飞书数据
+    print("\n📥 获取飞书数据...")
+    token = get_feishu_token()
+    print(f"Token获取成功: {token[:10]}...")
+    
+    data = get_sheet_data(token)

+    insert_data(data)
+    
+    # 4. 验证数据
+    print(f"\n🔍 验证结果...")
+    verify_data()
+    
+    print(f"\n🎉 任务完成！")
+```
+
+#### 步骤3：配置调度信息进行周期调度（可选）
+
+若需要定期从表中拉取数据，可直接配置该python任务的调度信息。
+
+例如：若需要每天早上8点定时拉取最新数据，则可进行如下配置
+
+1. 调度周期：每天调度
+2. 调度频率：执行一次、开始调度时间：08:00
+3. 生效日期：2025-06-11（希望任务开始运行的时间）
+
+![](.topwrite/assets/702bc8f656/0aabbf094597aaef2e4fcda3bb5a5f4cda9e35c8.png =300)
+
+### 方式二：使用离线任务的方式导入飞书数据
+
+当前离线任务的方式暂时不支持周期性抽取数据，只支持手动触发执行。
+
+#### 步骤1：获取tenant\_access\_token
+
+可使用python脚本获取**tenant\_access\_token**
+
+1. 登录云器Lakehouse控制台
+2. 进入"开发" → "Python任务"
+3. 点击"新建任务"
+
+配置任务信息：
+
+**任务名称**：获取飞书tenant_access_token
+
+```
+import requests  # 添加导入语句
+
+def get_feishu_token():
+    url = "https://open.feishu.cn/open-apis/auth/v3/tenant_access_token/internal"
+    data = {
+        "app_id": "cli_xxxxxxx",
+        "app_secret": "xxxxxxxxxxxxxx"
+    }
+    response = requests.post(url, json=data)
+    
+    # 添加错误处理（重要！）
+    if response.status_code != 200:
+        raise Exception(f"HTTP请求失败，状态码: {response.status_code}")
+    
+    json_data = response.json()
+    
+    # 检查飞书API返回的错误
+    if json_data.get("code") != 0:
+        raise Exception(f"飞书API错误: [{json_data.get('code')}] {json_data.get('msg')}")
+    
+    return json_data['tenant_access_token']
+
+# 调用函数并打印结果
+try:
+    result = get_feishu_token()
+    print(f"获取的租户访问令牌: {result}")
+except Exception as e:
+    print(f"获取token失败: {str(e)}")
+```
+
+^
+
+#### 步骤2：使用RestApi的方式创建飞书数据源
+
+1. 登录云器Lakehouse控制台
+2. 进入"管理-数据源"
+3. 新建数据源，选择RestApi
+
+> * 数据源名称：飞书数据
+> * URL地址：<https://open.feishu.cn/open-apis/sheets/v2/spreadsheets/>:**spreadsheetToken**/values/:**range**
+>   * spreadsheetToken：电子表格的 token
+>   * Range：格式为<sheetId>!<开始位置>:<结束位置>。参数信息可参考[飞书文档](https://open.feishu.cn/document/server-docs/docs/sheets-v3/data-operation/reading-a-single-range)
+> * 请求方式：GET
+> * KEY：Content-Type //固定值
+> * VALUE：application/json; charset=utf-8 //固定值
+> * 验证方法：不验证
+
+![](.topwrite/assets/702bc8f656/d60f2dd672cc92dd8344e17699256b288942d1e1.png =300)
+
+#### 步骤3：创建离线同步任务同步数据
+
+1. 登录云器Lakehouse控制台
+2. 进入"开发" → "离线同步"
+3. 点击"新建任务"
+
+> 来源目标配置：
+>
+> * 来源数据：选择同步的数据源：飞书数据。 数据源配置参考步骤2
+> * 请求参数：空
+> * 请求体：填写应用凭证  {   "app\_id": "cli\_xxxx",   "app\_secret": "xxxxxxxxxxxxxx"  }
+> * 请求头：key ：value  Content-Type：application/json; charset=utf-8  Authorization ：Bearer **tenant\_access\_token**
+> * 结果数据所处路径：你需要导入的数据的具体位置。可先不配置，通过点击预览数据确定数据位置后填写。
+>   &#x20; \-----------------------------------------------------------------------------------
+> * 目标数据：导入的数据地址。若是导入至云器lakehouse中，需先创建相应的table。（当前方式暂不支持快速建表）
+>   图例：数据对象表名为：test02\_feishu
+
+![](.topwrite/assets/702bc8f656/0c09f43f3b51860fa007c039db7a532a5a9f7cc5.png =300)
+
+字段映射配置：暂不支持嵌套数组格式的JSON解析，因此针对飞书API返回的数据，仅支持将value值以string类型导入至目标表中。
+| ------------------------------------------------------------------- |
+
+![](.topwrite/assets/702bc8f656/06c63b288c79f24b2781a479041ca4da24faf705.png =300)
+
+#### 步骤4：数据处理，将导入string字段处理成标准化表
+
+1. 前提：需要用户提前明确表结构。
+2. 登录云器Lakehouse控制台
+3. 进入"开发" → "SQL任务"
+4. 点击"新建任务"
+
+```
+-- 1. 创建目标表
+CREATE TABLE if not EXISTS test02_feishu_parsed (
+    name STRING,
+    id BIGINT
+);
+
+-- 2. 转换并插入数据
+INSERT INTO test02_feishu_parsed
+WITH parsed AS (
+    SELECT from_json(content, 'array<array<string>>') as arr
+    FROM test02_feishu
+    WHERE content IS NOT NULL
+),
+flattened AS (
+    SELECT explode(slice(arr, 2, size(arr))) as row_data
+    FROM parsed
+    WHERE size(arr) > 1
+)
+SELECT 
+    row_data[0] as name,
+    CAST(row_data[1] AS BIGINT) as id
+FROM flattened;
+
+-- 3. 查看结果
+SELECT * FROM test02_feishu_parsed;
+```
+
+## 4. **常见问题**
+
+### 问题1：使用python脚本和离线任务导入飞书数据的区别
+
+Python脚本导入：可支持定期调度飞书表格中的数据，但是需要用户熟悉Python语法。
+
+离线任务导入：提供无代码页面配置，操作门槛较低。但是当前暂不支持周期调度，后续版本会支持。
+
+### 问题2：开发过程中总是提示没有权限
+
+检查相关权限是否配置正确
+
+飞书应用中：是否是基于文件类型配置相应的权限。注意，url中sheet和wiki对应的权限都是有区别的，一定要选择正确的权限点。
+
+配置后是否发布审批：用户在配置权限后，还需点击发布，待管理员审批通过后才能获取权限点
+
+是否在飞书文档中为该应用配置了访问权限。此步骤非常重要！企业用户必须完成此配置才能通过API进行访问。

+# 如何上传json/jsonl文件导入到lakehouse的表中
+
+^
+
+## 前提条件
+
+当前仅支持以下标准格式的json/jsonl文件，若不符合规范则无法成功识别
+
+**JSONL格式**
+
+> * 每行一个完整的JSON对象
+> * 行之间用换行符（\n）分隔
+> * 不允许行尾有逗号
+> * 每行必须是有效的JSON
+> * 支持标准格式化的JSON行
+>   -----示例1---
+>   {"id": 1, "name": "Alice", "age": 30, "city": "New York"}{"id": 2, "name": "Bob", "age": 28, "city": "Los Angeles"}{"id": 3, "name": "Charlie", "age": 35, "city": "Chicago"}{"id": 4, "name": "Diana", "age": 32, "city": "Houston"}
+>   -----示例2---
+>   {"id": 1, "name": "Alice", "age": 30, "city": "New York"}
+>   {
+>   "id": 2,
+>   "name": "Bob",
+>   "age": 28,
+>   "city": "Los Angeles"
+>   }
+
+**JSON格式**
+
+> --JSON数组格式---
+> [{"id": 1, "name": "Alice", "age": 30, "city": "New York"},{"id": 2, "name": "Bob", "age": 28, "city": "Los Angeles"},{"id": 3, "name": "Charlie", "age": 35, "city": "Chicago"},{"id": 4, "name": "Diana", "age": 32, "city": "Houston"}]
+> --JSON格式化---
+> {
+> "id": 2,
+> "name": "Bob",
+> "age": 28,
+> "city": "Los Angeles"
+> }
+
+## 方案一：使用云器lakehouse web端上传功能导入
+
+**操作步骤**：
+
+在如下地方均可以点击「上传数据」
+
+* 实例首页->数据上传
+* 开发->数据树左侧
+* 数据资产地图->数据上传
+* 数据资产地图->数据管理->数据树->数据上传
+
+将符合标准格式规范的，且后缀是json/jsonl的文件拖拽/添加至上传区域，同时选择具体的配置信息，详细操作可见 [数据上传](<upload_data.md>)
+
+
+**上传到新表**
+
+| ![](.topwrite/assets/774c65e217/dcc4141809b8624f9869df74f16143d62d0c4618.jpeg =290) | ![](.topwrite/assets/774c65e217/620b74b85135aaf3f07902fc33d9fa1c6ce62ae0.jpeg =475) |
+| ----------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------- |
+
+当文件添加后，系统会给予json/jsonl的规则解析文件中的信息，并生成相应的字段名称、类型、以及具体的数值。
+
+当确定解析的信息准确无误后，可自定义勾选本次希望上传和导入的数据。
+
+点击确定后，系统会自动创建相应的表，同时将json文件的数据导入到该表中。
+
+**上传到已有表**
+
+| ![](.topwrite/assets/774c65e217/cd685005810b036910d46bd65780b5426676360e.png =259) | ![](.topwrite/assets/774c65e217/96a4ea3793bc69dedc0d9156a20b0d3a90df6167.jpeg =391) |
+| ---------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------- |
+
+* 选择目标表后，点击下一步，会列出目标表的具体字段。
+* 请确保目标文件中的数据有相应的字段信息，若存在字段和文件中字段不一致的场景，处理规则如下：
+* 若文件中没有目标表的字段，则该字段的数值默认为null
+* 若文件中有的字段没有在表中出现，则该字段默认不进行任何处理。
+* 若文件中的字段与表中的字段名一致，但是类型不一致，则该数值会被判定为错误数据。
+
+## 方案二：使用外部volume导入
+
+> 只支持每行是一个完整的JSON对象的形式导入，若文件中存在换行、格式化的场景，则无法解析。
+
+第一步：创建外部volume的链接
+
+```Plain
+```Plain
+CREATE STORAGE CONNECTION IF NOT EXISTS oss_test3   
+     TYPE oss    
+     ENDPOINT = '对应的endpoint'  
+     ACCESS_ID = '您的access_id'   
+     ACCESS_KEY = '您的access_key'   
+     COMMENTS = 'OSS public endpoint' ; 
+```
+
+第二步：创建外部volume
+
+```SQL
+CREATE EXTERNAL VOLUME  if not exists my_volume 
+LOCATION 'oss://json_file/' 
+USING CONNECTION oss_test3
+DIRECTORY = (enable=true, auto_refresh=true)
+RECURSIVE=true;
+```
+
+第三步：校验volume是否创建成功（可选）
+
+```Plain
+list VOLUME my_volume;
+```
+
+第四步：使用 sqlline 工具或 数据库管理工具。该命令暂不支持在 Studio 中运行。
+
+```Plain
+PUT '/Users/xxx/xxxx.json'  to  volume public.my_volume  file  'ods.json';
+```
+
+第五步：查询上传的json文件格式（可选）
+
+```Plain
+SELECT * FROM VOLUME my_volume  USING  json FILES('odst.json') LIMIT 5;
+```
+
+第六步：基于文件解析后的字段创建相应的lakehouse table（table创建过程略）并将数据导入到table中
+
+```Plain
+COPY INTO day_report_simple
+FROM VOLUME my_volume
+USING JSON
+FILES('ods.json');
+```
+
+QA
+
+问题一：使用数据上传功能上传的数据解析的字段不全
+
+使用数据上传功能默认只解析json中前1000行的字段信息，若1000行外的数据中有不同的key和value默认不会进行处理。
+
+问题二：为什么创建了CONNECTION和VOLUME但是依旧提示上传文件失败？
+
+当前在云器studio产品内，无法通过运行结果直接判断CONNECTION和VOLUME是否成功创建，建议参考方案二中的第三步判断是否创建成功。

+## AI\_COMPLETE
+
+`AI_COMPLETE` 是云器 Lakehouse 平台中用于生成式 AI 任务的核心标量函数。它允许用户在 SQL 环境中直接调用大规模语言模型（LLM），根据文本提示或多模态输入生成响应（补全），从而完成文本补全、翻译、情感分析、代码生成及复杂推理等任务。
+
+云器将 AI 计算下沉至存储层与执行引擎，确保数据在平台内部即可实现智能化处理，无需流转至外部环境，从而在保障数据安全的同时极大地降低了任务延迟。
+
+用户可以提供以下类型的输入：
+
+* **文本提示**：提供一个字符串形式的 Prompt，由模型生成响应。详见 AI\_COMPLETE（单字符串）。
+* **单张图像与文本提示**：提供一张图像和一个文本提示，由模型根据图像与提示生成响应。详见 AI\_COMPLETE（单图像）。
+
+### 语法
+
+该函数的语法取决于用户提供的输入类型：
+
+* AI\_COMPLETE（单字符串）
+* AI\_COMPLETE（单图像）
+
+## AI\_COMPLETE（单字符串）
+
+使用支持的语言模型，根据文本提示生成响应（补全）。
+
+### 语法
+
+sql
+
+```sql
+AI_COMPLETE(<model>,<prompt> [,<model_parameters>][,<response_format>][,<show_details>])
+```
+
+该函数包含 **2 个必需参数**和 **3 个可选参数**，支持位置参数语法和命名参数语法。
+
+### 参数说明
+
+**必需参数**
+
+\`\`（STRING）
+
+指定要调用的语言模型。模型的来源有两种：[模型管理](AI_Gateway.md) 中的**Endpoint** 和 **API Connection 连接对象**。在函数的第一个参数中，通过不同的前缀来区分模型来源。
+
+**来源一**：模型管理中的 Endpoint：
+
+模型管理是云器 Lakehouse 平台统一管理模型服务的网关层。在 API Gateway 中注册的模型可直接通过 `endpoint:` 前缀引用。
+
+**语法格式**：
+
+```scheme
+'endpoint:<endpoint名称>'
+```
+
+**使用示例**：
+
+```sql
+SELECT AI_COMPLETE('endpoint:lis_openai_llm','prompt string',GET_PRESIGNED_URL(VOLUME volume_name, '<relative_file_path>', <expiration_time>));
+```
+
+其中，`lis_openai_llm` 模型管理 endpoint 是由平台管理员在 API Gateway 中预先配置，包含模型供应商、模型版本、认证凭据等信息。普通用户无需关心底层连接细节，只需通过端点名称即可调用对应模型。
+
+***
+
+**来源二**：API Connection 连接对象
+
+API Connection 是用户在 Lakehouse 中自行创建的模型服务连接对象，适用于需要自定义模型服务地址、认证密钥或对接私有化部署模型的场景。通过 `CREATE API CONNECTION` 语句创建连接对象后，即可在 `AI_COMPLETE` 中引用。
+
+**创建连接对象语法**：
+
+sql
+
+```sql
+CREATE API CONNECTION <connection_name>
+    TYPE ai_function
+    PROVIDER = '<provider_name>'
+    BASE_URL = '<service_endpoint_url>'
+    API_KEY = '<your_api_key>';
+```
+
+**创建连接对象示例**：
+
+```sql
+CREATE API CONNECTION conn_bailian
+    TYPE ai_function
+    PROVIDER = 'bailian'
+    BASE_URL = 'https://dashscope.aliyuncs.com/api/v1'
+    API_KEY = 'sk-xxxxxxxxxxxxxxxxxxxxxxxx';
+```
+
+其中各字段含义如下：
+
+`connection_name` 为连接对象的自定义名称，后续在 `AI_COMPLETE` 中通过该名称引用；
+
+`TYPE` 固定为 `ai_function`，表示该连接用于 AI 函数调用；
+
+`PROVIDER` 指定模型供应商标识，如 `'bailian'`（百炼）、`'openai'`、`'anthropic'` 等；
+
+`BASE_URL` 为模型服务的 API 基础地址；`API_KEY` 为调用该服务所需的认证密钥。
+
+***
+
+**在 AI\_COMPLETE 中引用连接对象**：
+
+```sql
+SELECT AI_COMPLETE('connection:conn_bailian','请简要介绍量子计算的基本原理。');
+```
+
+**语法格式**：
+
+```scheme
+'connection:<连接对象名称>'
+```
+
+###
+
+### 示例
+
+**基础用法：单个文本提示**
+
+```
+SELECT AI_COMPLETE(
+    'endpoint:aliyun-qwen3max',
+    '中国的首都在哪里?'
+);
+
+```
+
+**图像识别**：
+
+使用支持的多模态语言模型，根据单张图像与文本提示生成响应（补全）。该模式适用于视觉问答（VQA）、图像内容描述、图像信息提取、OCR 识别等需要模型理解图像内容的场景。
+
+```

+## AI\_EMBEDDING
+
+使用支持的嵌入模型（Embedding Model）将文本转换为高维向量表示。生成的向量可用于语义搜索、文本相似度计算、聚类分析、推荐系统等下游任务。
+
+### 语法
+
+```sql
+AI_EMBEDDING(<model>, <input> [ , <model_parameters> ])
+```
+
+该函数包含 **2 个必需参数**和 **1 个可选参数**，支持位置参数语法和命名参数语法。
+
+### 参数说明
+
+**必需参数**
+
+**`model`**
+
+指定要调用的嵌入模型。与 `AI_COMPLETE` 一致，模型来源分为两种：API Gateway 端点和 API Connection 连接对象。
+
+通过 API Gateway 端点调用时，使用 `endpoint` 前缀加端点名称的格式：
+
+```scheme
+'endpoint:<端点名称>'
+```
+
+通过 API Connection 连接对象调用时，需先通过 `CREATE API CONNECTION` 创建连接，再使用 `connection/` 前缀引用：
+
+```scheme
+'connection:<连接对象名称>'
+```
+
+> **说明**： 请确保所指定的模型为嵌入模型（Embedding Model），而非对话补全模型。嵌入模型专门用于将文本映射为固定维度的数值向量，常见的嵌入模型包括 OpenAI 的 `text-embedding-3-small`、`text-embedding-3-large`，阿里云百炼的 `text-embedding-v4` 等。
+
+**`\`**（STRING）
+
+需要转换为向量的输入文本。可以是单个词语、一个句子、一段文字，也可以是来自数据表中某个字段的值。输入文本的最大长度受所选模型的上下文窗口限制，超出限制可能导致文本被截断或调用失败。
+
+**可选参数**
+
+**`\`**（OBJECT）
+
+以 JSON 对象形式传入的模型超参数，用于控制嵌入模型的行为。不同模型支持的参数可能有所不同，常见参数如下：
+
+| 参数                    | 类型     | 说明                                                                                                                      |
+| --------------------- | ------ | ----------------------------------------------------------------------------------------------------------------------- |
+| `input`               | STRING | 指定输入内容的类型。常见取值为 `'text'`（普通文本）和 `'query'`（查询文本）。部分模型会根据输入类型对向量做针对性优化，例如在检索场景中，文档内容使用 `'text'`，用户查询使用 `'query'`，可提升检索精度。 |
+| `embedding.dimension` | STRING | 指定输出向量的维度。较高的维度通常能保留更丰富的语义信息，但会占用更多存储空间和计算资源。常见取值包括 `'256'`、`'512'`、`'1024'`、`'1536'` 等，具体支持的维度范围取决于所选模型。               |
+
+参数示例：
+
+```sql
+JSON '{
+    "input": "text",
+    "embedding.dimension": "1024"
+}'
+```
+
+### 示例

+
+#### 3.1.2 外部模型接入（企业自有模型集成）
+
+**业务价值**：支持企业将私有化部署或自有版权的模型接入 AI Gateway，实现统一管控（如金融风控模型、电商推荐模型）。
+分两类场景接入，满足不同模型规范需求：
+**场景一：标准厂商接入（如火山引擎、Anthropic）**
+优势：模型符合云厂商标准接口规范，无需自定义 URL
+
+1. 进入「模型管理 → Endpoint → 新建 → 外部模型」；
+2. 填写配置：
+   * 输入「Endpoint 名称」（租户内唯一，如 “finance-risk-model”）；
+   * 选择「厂商」（系统自动填充标准 Base URL）；
+   * 单选「模型分类」（LLM/Embedding/Image Generation）；
+   * 输入「模型版本」（如 “risk-v2.1”）；
+   * 填写「API KEY ID」（仅调用外部模型时需要 API Key 信息，您可在 API KEY 界面创建，并根据生成的 API Key 查看具体 ID 信息）；
+3. AI Gateway 配置：
+   * 设置「访问限流」（如 TPM=1000，RPM=50）
+   * 「访问配额」（如每月 10 万 Token）；
+4. 点击「测试连接」，验证连通性（失败排查见第四章）；
+5. 测试通过后点击「确定」，Endpoint 加入列表。
+   \</.topwrite/assets/image (2).png>)
+
+**场景二：自定义接入（符合 OpenAI 规范）**
+优势：企业自研模型、第三方非标准厂商模型
+
+1. 进入「模型管理 → Endpoint → 新建 → 外部模型 → 自定义」；
+2. 填写配置：
+   * 输入「Endpoint 名称」（如 “custom-ocr-model”）；
+   * 填写「模型厂商」（如 “企业自研”）；
+   * 单选「模型分类」（如 “Image Generation”）；
+   * 输入「模型版本」（自定义，如 “20260120-beta”）；
+   * 填写「Base URL」（如 “<https://internal-ocr.example.com/v1/chat/completions>”）；
+   * 填写「API KEY ID」（仅调用外部模型时需要 API Key 信息，您可在 API KEY 界面创建，并根据生成的 API Key 查看具体 ID 信息）；
+3. 后续步骤同 “标准厂商接入” 3-5 步。
+   \</.topwrite/assets/image (3).png>)
+
+#### 3.1.3 模型监控（实时掌握运行状态）
+
+**业务价值**：实时监控模型调用成功率、延迟、错误率，及时发现异常（如模型宕机、限流触发）。
+**操作步骤**：
+
+1. 进入「模型管理 → Endpoint」，选择目标 Endpoint，点击「更多 → 监控」；
+   \</.topwrite/assets/image (4).png>)
+2. 配置查询条件：
+   * 时间范围：默认近 1 天，支持 1 分钟～60 天（不同范围数据粒度不同，如 1 天内为 1 分钟 / 点，30 天内为 1 小时 / 点）；
+   * 指标维度：默认展示「请求次数、成功率、端到端延迟、Token 总用量」；
+3. 查看数据：
+   * 概览面板：展示核心 KPI（Token 总量、成功率、错误率、平均延迟）；
+   * 趋势图表：折线图展示指标变化（如成功率骤降需排查模型连通性）；
+   * 错误明细：点击「错误率」可查看错误类型（如限流、权限不足）；
+
+### 3.2 API KEY 管理（安全访问凭证）
+
+**业务价值**：API KEY 是模型外部调用的唯一凭证，严格管理可防止资源滥用与数据泄露。
+**操作步骤（仅 Gateway Admin）**：
+
+1. 进入「模型管理 → API KEY」页面；
+2. 新建 API KEY：
+   * 点击「新建 KEY」→ 输入名称（需关联业务场景，如 “ecommerce-recommend-key”）；
+   * 点击「确认」，系统生成 KEY；
+3. 日常管理：
+   * 禁用/启用：点击「禁用」（禁用后无法调用，适用于临时停用），需用时点击「启用」；
+   * 删除：需先停用关联调用（如 SQL/OpenAPI 调用），点击「删除」→ 确认（KEY 立即失效）；
+   * 筛选：通过「状态（正常 / 禁用）」「负责人」快速定位目标 KEY；
+4. 安全注意事项：
+   * 避免明文存储（如代码仓库、配置文件）；
+   * 定期轮换（建议每 3 个月）；
+   * 泄露后需立即删除并新建，更新所有关联调用配置；
+     \</.topwrite/assets/image (5).png>)
+
+### 3.3 权限管理（精细化资源控制）
+
+#### 3.3.1 Gateway Admin 管理（全局权限管控）
+
+**业务价值**：确保企业有且仅有授权人员负责全局配置，避免权限混乱。
+**操作步骤（仅当前 Gateway Admin）**：
+
+1. 进入「模型管理 → 权限 → Gateway 管理员」；
+2. 添加管理员：
+   * 点击「添加」→ 勾选目标用户（需在租户内已注册）；
+   * 点击「确认」，用户立即获得 Gateway Admin 全量权限；
+3. 删除管理员：
+   * 在列表找到目标用户，点击「移除」；
+   * 系统校验：① 不可删除当前登录用户；② 删除后需至少保留 1 名 Admin；
+4. 查看记录：页面展示所有 Admin 的「用户名、添加时间、操作人」；
+   \</.topwrite/assets/image (6).png>)
+
+#### 3.3.2 Endpoint 权限管理（业务线权限隔离）
+
+**业务价值**：按业务线分配 Endpoint 权限，避免跨业务资源滥用（如电商 Endpoint 仅电商团队可调用）。
+**操作步骤（仅 Endpoint Admin）**：
+
+1. 进入「模型管理 → 权限 → Endpoint 权限」；
+2. 授权操作：
+   * 点击「添加」→ 选择目标用户 → 勾选权限类型（参考 2.2 角色权限）；
+   * 选择需授权的 Endpoint（可多选）；
+   * 点击「确认」，用户获得对应权限；
+3. 收回权限：
+   * 在「已授权列表」找到目标用户与 Endpoint；
+   * 点击「移除」→ 确认，权限立即失效；
+     \</.topwrite/assets/image (7).png>)
+
+### 3.4 配额与用量管理（成本控制）
+
+#### 3.4.1 租户配额配置（企业级预算管控）
+
+**业务价值**：设置企业月度 Token 总上限，避免超预算（如每月 500 万 Token，覆盖全业务线）。
+**操作步骤（仅 Gateway Admin）**：
+
+1. 进入「模型管理 → 用量 → 租户配额」；
+2. 首次配置：
+   * 若为空态（提示 “当前租户尚未设置配额”），点击「设置租户配额」；
+   * 填写配置：粒度默认「租户级别」、周期默认「每月」、Token 配额（如 5000000，即 500 万 / 月）；
+   * 点击「保存」，跳转至配额页查看「总配额、已用量、剩余量、每日用量趋势」；
+3. 调整配额：点击「编辑配额」→ 修改数值 → 保存（实时生效）；
+   \</.topwrite/assets/image (8).png>)
+
+#### 3.4.2 Endpoint 配额配置（业务线预算分配）
+
+**业务价值**：为单个 Endpoint 分配独立配额（如电商推荐模型每月 100 万 Token），实现业务线成本隔离。
+**操作步骤（Gateway Admin/Endpoint Admin）**：
+
+1. 进入「模型管理 → Endpoint」，选择目标 Endpoint，点击「编辑」；
+2. 找到「AI Gateway → 访问配额」模块；
+3. 填写配置：粒度默认「Endpoint 级别」、周期「每月」、Token 配额（如 1000000）；
+4. 关键规则：实际可用配额 = 租户配额与 Endpoint 配额的较小值（如租户剩 50 万，Endpoint 配额 100 万，实际可用 50 万）；
+5. 点击「保存」，在 Endpoint 详情页查看配额使用情况；
+   \</.topwrite/assets/image (9).png>)
+
+#### 3.4.3 用量统计查询（多维度成本归因）
+
+**业务价值**：按 Endpoint / 用户 / API KEY 维度查询用量，定位高成本资源（如某用户调用量异常）。
+**操作步骤（角色权限差异）**：
+
+1. 进入「模型管理 → 用量 → 用量统计」；
+2. 配置查询条件：
+   * 时间范围：默认近 1 月，支持切换「近 1 周 / 自定义」；
+   * 统计维度：
+     * 普通用户：仅查看「自身关联的 Endpoint / 用户」；
+     * Gateway Admin：查看「Endpoint / 用户 / API KEY / 账户 / 账号明细」；
+3. 查看数据：
+   * 列表视图：展示「统计维度、日期、调用次数、输入 Token、输出 Token、总用量」；
+   * 图表视图：点击「切换图表」，通过折线图 / 柱状图查看用量趋势；
+4. 下载明细（仅 Gateway Admin）：
+   * 点击「下载明细」→ 选择年月（支持最近 1 年）→ 确认；
+     \</.topwrite/assets/image (10).png>)
+
+### 3.5 多场景模型调用（适配不同用户需求）
+
+#### 3.5.1 SQL 调用（数据分析师 / 开发工程师）
+
+**业务价值**：直接在 SQL 中调用模型，实现 “数据查询 + AI 分析” 一体化（如订单文本嵌入、用户评论情感分析）。
+您可以在SQL中直接调用，例如：
+
+```Plain
+select ai_complete('endpoint\:lis\_aliyun\_qwen\_max','中国首都是哪里？')
+```
+
+#### 3.5.2 DataGPT 调用（所有角色操作）
+
+DataGPT 通过标准化接口实现 AI 模型调用，可快速完成模型对接与替换。您只需在 DataGPT 的模型配置界面，将我方提供的专属调用地址（Base URL）与访问凭证（API Key），替换平台现有模型配置，即可完成模型调用链路的切换，依托 AI Gateway 实现稳定、可管控的 AI 能力调用。
+
+#### 3.5.3 OpenAPI 标准调用（开发场景）
+
+* 调用地址：Endpoint 列表中的 “访问地址”；
+* API KEY：从「API KEY 管理」中获取（仅 Gateway Admin 可创建）；
+* 调用方式：
+  * 进入「模型管理 → Endpoint」页面，点击 Endpoint 名称，进入详情页；
+  * 在详情页的下方，「Endpoint 调用示例」部分，为您展示 OpenAI-python 和 REST API-cURL 两种调用方式的示例。
+
+## 四、关键注意事项
+
+1. **权限控制**：操作前确认自身角色权限（如普通用户不可删除 Endpoint），避免因权限不足导致操作失败；如需扩展权限，联系对应 Admin（Gateway Admin 负责全局权限，Endpoint Admin 负责业务线权限）。
+
+2. **数据留存**：
+   * 账号明细数据：仅保留最近 1 年，需长期存储需每月下载备份（Gateway Admin 操作）；
+   * 用量监控数据：最多保留 60 天，关键指标（如月度配额使用情况）需定期截图存档。
+
+3. **模型删除风险**：
+   * Endpoint 删除后不可恢复，删除前需：① 停用所有关联调用（SQL/OpenAPI/DataGPT）；② 通知所有有权限用户；
+   * 内置托管模型删除后，需重新使用时联系技术支持（不可自行恢复）。
+
+4. **API KEY 安全**：
+   * 避免泄露（如明文分享、存储在代码仓库）；
+   * 定期轮换（建议每 3 个月）；
+   * 泄露后需立即在「API KEY 管理」中删除并重新创建，更新所有关联配置。
+
+5. **配额生效规则**：Endpoint 实际可用配额 = 租户配额与 Endpoint 配额的较小值，设置时避免 Endpoint 配额远超租户配额（如租户每月 100 万，Endpoint 设 200 万，实际仅 100 万可用，造成配置浪费）。
+
+6. **兼容性注意**：外部模型需符合 OpenAI 接口规范，否则无法接入（如不支持 “messages” 参数的模型需厂商适配）；编辑模型版本时，需确认下游调用系统是否支持新版本（避免兼容性问题）。

+# AI 函数
+
+## 概述
+
+在云器 Lakehouse 中，AI 函数的实现**依托于**外部函数（External Function）的框架。外部函数（亦称远程函数，Remote Function）是一种特殊的自定义函数（UDF），它允许用户通过 Python 或 Java 语言定义函数逻辑，但其核心计算任务会被\*\*卸载（offload）\*\*到外部的远程服务执行（支持的远程服务包括：阿里云的函数计算 FC、腾讯云的云函数 SCF）。在执行过程中可调用：
+
+* **在线服务**：以 API 形式对外提供的在线服务，如 AI 在线模型服务（例如大语言模型 API、云平台提供的在线 AI API 服务）。
+* **离线功能**：将特定功能函数代码、依赖库、模型和数据等文件打包成的离线服务包，如从 Hugging Face 下载的图像识别模型等。
+
+云器 Lakehouse 通过创建 API Connection，在元数据中保存外部函数计算服务的连接和访问信息。外部函数通过 HTTP 协议调用外部函数计算服务，实现数据处理并返回结果。
+![](.topwrite/assets/a7546df1-be39-41e9-9c80-e0e90ce3d353.svg)
+Lakehouse 平台在获得用户预先授权后，于创建外部函数时，将自动在客户账号下的函数计算服务中部署该函数。当用户在 SQL 查询中使用外部函数时，由外部函数实现与外部计算服务的安全连接、数据处理并返回查询结果。

+## 功能描述
+
+`ALTER SCHEMA` 语句用于调整指定 schema 的名称、属性和注释。通过该语句，用户可以更新 schema 的注释（comment）和属性（properties），以适应数据处理需求和组织结构的变化。
+
+## 修改 Schema 的名称
+
+语法：
+
+```SQL
+ALTER SCHEMA schema_name RENAME TO new_name;
+```
+
+## 修改 Schema 注释
+
+要修改 schema 的注释，可使用以下语法：
+
+```SQL
+ALTER SCHEMA schema_name SET COMMENT  'new_comment';
+```
+
+### 示例
+
+1. 修改 `rc4_l` schema 的注释为 `rc7`：
+
+   ```SQL
+   ALTER SCHEMA rc4_l SET COMMENT 'rc7';
+   ```
+
+   执行该语句后，使用 `DESC` 命令验证注释是否修改成功：
+
+   ```SQL
+   DESC SCHEMA rc4_l;
+   ```
+
+   预期输出结果：
+
+   ```
+   +--------------------+-------------------------+
+   |     info_name      |       info_value        |
+   +--------------------+-------------------------+
+   | name               | rc4_l                   |
+   | creator            | UAT_TEST                |
+   | created_time       | 2023-12-15 20:38:14.126 |
+   | last_modified_time | 2023-12-20 14:54:59.826 |
+   | comment            | rc7                     |
+   +--------------------+-------------------------+
+   ```
+
+## 修改 Schema 属性
+
+除了修改注释，还可以为 schema 设置或更新属性。使用以下语法：
+
+```SQL
+ALTER SCHEMA schema_name SET PROPERTIES (key1 = 'value1', key2 = 'value2', ...);
+```
+
+### 示例
+
+1. 为 `rc4_l` schema 设置属性 `custom_property` 为 `true`：
+
+   ```SQL
+   ALTER SCHEMA rc4_l SET PROPERTIES (custom_property = 'true');
+   ```
+
+   查看 schema 属性是否设置成功：
+
+   ```SQL
+   DESC SCHEMA rc4_l;
+   ```
+
+   预期输出结果中的 properties 部分应包含新设置的属性：
+
+   ```
+   +--------------------+-------------------------+
+   |     info_name      |       info_value        |
+   +--------------------+-------------------------+
+   | ...                 | ...                      |
+   | properties          | {custom_property='true'} |
+   +--------------------+-------------------------+
+   ```
+
+## 权限要求
+
+执行 `ALTER SCHEMA` 语句的用户必须拥有对应 schema 的 ALTER 权限。如果没有相应权限，操作将被拒绝。

+
+# 添加字段
+
+## 语法
+
+```sql
+-- 添加列
+ALTER TABLE table_name ADD COLUMN
+      column1_name_identifier data_type [COMMENT comment]
+      [FIRST | AFTER column1_name_identifier | BEFORE column1_name_identifier ]  ,....

+    --map key 添加字段
+    column_name.KEY.struct_column_name 
+    --map value添加字段
+    column_name.VALUE.struct_column_name    
+```
+
+## 参数说明
+
+* **column_name_identifier**：字段标识符，用于指定添加、删除或重命名的字段名。
+* **FIRST | AFTER column_name_identifier**：指定字段添加的位置，可以添加到字段之前或之后。
+
+## 使用示例
+
+1. 添加普通字段：
+
+   ```sql
+   ALTER TABLE my_table ADD COLUMN new_column INT;
+   ```
+
+2. 添加复杂类型字段：
+
+   ```sql
+   CREATE TABLE my_complex_table (
+       point STRUCT<x: INT, y: DOUBLE>,
+       points ARRAY<STRUCT<x: DOUBLE, y: DOUBLE>>,
+       points_map MAP<STRUCT<x: INT>, STRUCT<a: INT>>
+   );
+
+   -- 在struct中添加字段
+   ALTER TABLE my_complex_table ADD COLUMN point.z DOUBLE;
+
+   --map value中struct添加字段
+   ALTER TABLE my_complex_table ADD COLUMN points_map.value.b INT;
+
+   --map key中struct添加字段
+   ALTER TABLE my_complex_table ADD COLUMN points_map.key.y INT;
+
+   --array中struct添加字段
+   ALTER TABLE my_complex_table ADD COLUMN points.element.z DOUBLE;
+   --添加多个字段同时指定位置
+    CREATE TABLE test (a string);
+    ALTER TABLE test  ADD COLUMN b string, c string, CHANGE COLUMN a AFTER c;
+
+   ```
+
+# 删除字段

+
+**DECIMAL 类型的两个参数**
+
+```

+```
+
+例如：`DECIMAL(10, 2)` 表示
+
+* 总共 10 位数字
+* 其中 2 位是小数位
+
+**场景 1：两个参数都增大**
+
+```sql
+-- 源表定义
+CREATE TABLE test_alter(a DECIMAL(10,2));
+-- ✅ 正确：整数位和小数位都增大
+ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(12,2);
+-- 说明：从 10 位增加到 12 位，小数位不变
+ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(13,3);
+-- 说明：从 10 位增加到 13 位，小数位从 2 增加到 3
+```
+
+**场景 2：只增大整数位，小数位不变**
+
+```sql
+ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(15,2);
+-- 从 DECIMAL(10,2) 转为 DECIMAL(15,2)
+-- 整数位：从 8 位（10-2）增加到 13 位（15-2）
+```
+
+**场景 3：同时增大整数位和小数位**
+
+```sql
+ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(20,5);
+-- 从 DECIMAL(10,2) 转为 DECIMAL(20,5)
+-- 整数位增大，小数位也增大
+-- 这是最安全的转换方式
+```
+
+❌ 错误的类型转换
+
+**错误 1：整数位不变，只增大小数位**
+
+```sql
+-- ❌ 错误
+ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(10,3);
+-- 原因：总位数不变，只是改变了小数位比例
+-- 结果：系统会报错或数据可能丢失
+```
+
+**错误 2：减少任一参数**
+
+```sql
+-- ❌ 错误：减少总位数
+ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(8,2);
+-- ❌ 错误：减少小数位
+ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(12,1);
+-- ❌ 错误：两个都减少
+ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(8,1);
+```
+
+**错误 3：只增大小数位**
+
+```sql
+-- ❌ 错误
+ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(10,3);
+-- 问题：总位数从 10 不变为 10，但小数位从 2 增加到 3
+-- 结果：整数位从 8 减少到 7，可能导致数据溢出或精度丢失

+# ARRAY
+`ARRAY`是一种数据类型，用于表示由同一种类型的元素序列构成的值。这种数据类型可以存储一系列具有相同数据类型的元素，方便进行统一管理和操作。
+
+## 语法
+
+```sql
+ARRAY <elementType>
+```
+- `elementType`：指定数组中元素的数据类型。
+
+## ARRAY常量格式
+```
+select [1,3,4];
+```
+这种格式表示一个数组常量。请确保在定义数组常量时**不使用引号**，因为引号会使其被识别为字符串类型，而字符串类型的`'[1,3,4]'`不能直接被使用 `CAST` 转化成`array<int>`类型。
+
+## 示例
+
+1. 创建一个整数数组：
+
+```sql
+SELECT ARRAY(1, 2, 3);
+```
+执行结果：
+| result    |
+| --------- |
+| [1, 2, 3] |
+
+2. 将整数数组转换为字符串数组：
+
+```sql
+SELECT CAST(ARRAY(1, 2, 3) AS ARRAY<STRING>);
+```
+执行结果：
+| result          |
+| --------------- |
+| ["1", "2", "3"] |
+
+3. 获取数组元素的数据类型：
+
+```sql
+SELECT typeof(ARRAY(1.2, 1.4, 1.8));
+```
+执行结果：
+| result              |
+| ------------------- |
+| array<decimal(2,1)> |
+
+4. 创建一个嵌套数组（数组中包含其他数组）：
+
+```sql
+SELECT CAST(ARRAY(ARRAY(10, 20), ARRAY(30, 40)) AS ARRAY<ARRAY<DECIMAL(10,2)>>);
+```
+执行结果：
+| result                           |
+| -------------------------------- |
+| [[10.00, 20.00], [30.00, 40.00]] |
+
+5. 获取数组中的特定元素：
+
+```sql
+SELECT a[0] FROM VALUES(ARRAY(10, 20, 30)) AS T(a);
+```
+执行结果：
+| result |
+| ------ |
+| 10     |
+
+6. 使用`ARRY_CONTAINS`检查数组中是否存在特定元素：
+
+```sql
+SELECT array_contains(ARRAY(1, 2, 3),3);
+```
+执行结果：
+| Result |
+| ------ |
+| true   |
+
+7. 对数组进行排序：
+
+```sql
+SELECT ARRAY_SORT(array(2, 1, 3));
+```
+执行结果：
+| result    |
+| --------- |
+| [1, 2, 3] |
+
+8. 合并两个数组：
+
+```sql
+SELECT array_union(array(2, 1, 3, 3), array(3, 5));
+```
+执行结果：
+| result    |
+| --------- |
+| [2,1,3,5] |

+# 基于云器Lakehouse构建面向分析的Modern Data Stack
+
+本文介绍如何基于云器Lakehouse、Metabase和MindsDB构建面向分析的Modern Data Stack。
+
+
+
+## 方案架构
+
+基于云器Lakehouse的Modern Data Stack方案特点：
+
+* 实现从AWS数据仓库到数据湖的演进，通过云器Lakehouse实现湖仓一体的优化提升，大幅降低数据存储、计算和运维成本。
+* 无限存储与高效迁移：全链路数据通道采用云对象存储实现存算分离架构，避免了传统方案中服务器节点的带宽和存储容量瓶颈。
+* 云器Lakehouse + Metabase：实现极简的BI数据分析，仅需点击两次鼠标即可完成可视化数据探索和分析，极大降低业务人员分析数据的门槛，对业务人员十分友好。
+* 云器Lakehouse + MindsDB：实现100%基于SQL的AI与LLM增强分析。无需掌握其他复杂语言，数据工程师和BI分析人员基于SQL就可以实现AI和LLM的增强分析。
+* 降低数据全栈（云基础设施、数据湖、数据仓库、BI、AI）对技术人员的要求，降低企业用人门槛，提升人才可得性。
+
+本方案主打简单易用，旨在帮助企业将工作重点从数据基建转向数据分析，实现数据分析的现代化。
+
+![](.topwrite/assets/image_1734577522644.png)
+
+
+
+上图展示了迁移至并基于云器Lakehouse构建Modern Data Stack的架构，概述如下：
+
+* 使用Redshift UNLOAD命令将数据卸载到S3存储桶中的Parquet文件。
+* 通过云器Lakehouse的 `SELECT * FROM VOLUME` 语句，将AWS S3存储桶中Parquet文件的数据直接加载到云器Lakehouse的表中，实现快速数据入仓（本例中加载2000多万行的一张表，完成数据入仓仅需30秒）。
+* BI应用：通过Metabase探索和分析数据（从表格到仪表盘仅需点击两次鼠标——没错，就是两次）。
+* AI应用：通过MindsDB对房价进行预测（100%用SQL实现模型预测）。
+
+## 方案组成
+
+* AWS：
+
+  * Redshift
+  * S3
+
+* 云器
+
+  * 云器Lakehouse，多云及一体化数据平台。采用SaaS全托管服务模式，为企业提供极简数据架构。
+  * 云器Lakehouse Driver for Metabase
+  * 云器Lakehouse Connector for MindsDB
+
+* 数据分析
+
+  * Metabase with Lakehouse Driver on Docker：Metabase是一个完整的BI平台，但在设计理念上与Superset大不相同。Metabase非常注重业务人员（如产品经理、市场运营人员）的使用体验，让他们能自由地探索数据，回答自己的问题。
+  * MindsDB with Lakehouse Connector on Docker：MindsDB可直接在云器Lakehouse中进行建模，省去了数据处理、模型搭建等专业步骤。数据分析人员、BI分析师无需熟悉数据工程、建模知识，即可开箱使用，降低了建模门槛，让人人都是数据分析师，人人都会应用算法。
+  * Zeppelin with Lakehouse JDBC Interpreter on Docker
+  * Zeppelin with MySQL JDBC Interpreter on Docker（连接MindsDB的MySQL接口）
+
+## 为什么要使用云器Lakehouse？
+
+* **完全托管**： 云器Lakehouse提供完全托管、基于云的Lakehouse服务，易于使用和扩展。这意味着您不必担心管理和维护自身的硬件与基础设施，避免了耗时且昂贵的投入，实现安心托付。
+* **节省成本**：与Redshift相比，云器Lakehouse的总拥有成本（TCO）通常较低，因为它根据使用情况收费，而不需要预先承诺。云器Lakehouse高度灵活的定价模型使您只需为实际使用的资源付费，而无需被锁定在固定成本模型中。
+* **可扩展性**： 云器Lakehouse 旨在处理大量数据，并且可以根据需要扩展或缩小，这对计算负载波动明显的企业来说是一个不错的选择。云器Lakehouse数据存储在云上的对象存储服务中，在数据规模上实现“无限扩展”。
+* **性能**： 云器Lakehouse采用Single Engine All Data架构，实现计算与存储分离，使其能够比Redshift更快地处理查询。
+* **易于使用**： 云器Lakehouse提供了一体化的数据集成、开发、运维和治理平台，这使得开发和管理变得更加容易，无需复杂的方案集成。
+* **数据源支持**： 云器Lakehouse支持多种数据源和格式，包括结构化和半结构化数据，大多数情况下仅用SQL就可完成BI和AI应用的开发。
+* **数据集成**： 云器Lakehouse内置的数据集成功能支持广泛的数据源，使数据加载和准备变得更加容易，从而便于进行分析。
+  总体而言，迁移到云器Lakehouse可以帮助您节省时间和金钱，并使您能够更轻松、更有效地处理和分析数据。
+
+## 实施步骤
+
+### 数据抽取（E）
+
+#### 将房价销售数据从Redshift卸载到S3
+
+Redshift UNLOAD 命令：使用 Amazon S3 服务器端加密 (SSE-S3) 将查询结果卸载到 Amazon S3 上的一个或多个文本、JSON 或 Apache Parquet 文件。
+
+```SQL
+UNLOAD ('select-statement')
+TO 's3://object-path/name-prefix'
+authorization
+[ option, ...] 
+
+where authorization is
+IAM_ROLE { default | 'arn:aws:iam::<AWS account-id-1>:role/<role-name>[,arn:aws:iam::<AWS account-id-2>:role/<role-name>][,...]' }
+            
+where option is
+| [ FORMAT [ AS ] ] CSV | PARQUET | JSON
+| PARTITION BY ( column_name [, ... ] ) [ INCLUDE ]
+| MANIFEST [ VERBOSE ]
+| HEADER
+| DELIMITER [ AS ] 'delimiter-char'
+| FIXEDWIDTH [ AS ] 'fixedwidth-spec'
+| ENCRYPTED [ AUTO ]
+| BZIP2
+| GZIP
+| ZSTD
+| ADDQUOTES
+| NULL [ AS ] 'null-string'
+| ESCAPE
+| ALLOWOVERWRITE
+| CLEANPATH
+| PARALLEL [ { ON | TRUE } | { OFF | FALSE } ]
+| MAXFILESIZE [AS] max-size [ MB | GB ]
+| ROWGROUPSIZE [AS] size [ MB | GB ]
+| REGION [AS] 'aws-region' }
+| EXTENSION 'extension-name'
+```
+
+#### 数据湖数据探索：通过云器Lakehouse探索AWS S3上的Parquet数据
+
+查看总共有多少行数据（需要提前创建好云器Lakehouse的 `STORAGE CONNECTION` 和 `EXTERNAL VOLUME`）：
+
+![](.topwrite/assets/image_1718933981338.png)
+
+预览数据
+
+```SQL
+select 
+        *
+    from volume hz_qiliang_csv_volume(
+    price  int,
+    date  int,
+    postcode1  binary,
+    postcode2  binary,
+    type  binary,
+    is_new  int,
+    duration  binary,
+    addr1  binary,

+    district  binary,
+    county  binary
+) USING parquet
+regexp '/house_prices_iceberg/data/000.*.parquet'
+limit 10;
+```
+
+在云器Lakehouse执行上述查询，结果如下：

+# BIGINT
+
+`BIGINT` 是一种数据类型，用于表示 8 字节的带符号整数。它的数值范围为 -9,223,372,036,854,775,808 到 9,223,372,036,854,775,807。这种类型通常用于存储非常大的整数值。
+
+## 语法
+
+```
+BIGINT [ + | - ] digit [ ... ] [L]
+```
+
+- `digit`：表示 0 到 9 的任意数字。
+- `L`：表示字面量后缀，用于指示这是一个 `BIGINT` 类型的数值。如果数值不在 `INT` 范围内，即使没有 `L` 后缀，也会自动转换为 `BIGINT` 类型。
+
+## 使用示例
+
+1. 插入一个正数 `BIGINT` 值：
+
+```
+INSERT INTO my_table (my_column) VALUES (+1L);
+```
+
+2. 插入一个负数 `BIGINT` 值：
+
+```
+INSERT INTO my_table (my_column) VALUES (-1L);
+```
+
+3. 插入一个不带 `L` 后缀的 `BIGINT` 值（如果数值在 `INT` 范围内，会隐式转换为 `INT` 类型）：
+
+```
+INSERT INTO my_table (my_column) VALUES (123456789);
+```
+
+4. 在查询中使用 `BIGINT` 类型的数值进行比较：
+
+```
+SELECT * FROM my_table WHERE my_column = 9223372036854775807;
+```
+
+5. 使用 `CAST` 函数将其他类型的数值转换为 `BIGINT`：
+
+```
+SELECT CAST(123.456 AS BIGINT);
+```
+
+## 注意事项
+
+- 当使用 `BIGINT` 类型存储数值时，请确保数值在允许的范围内，否则可能会导致溢出错误。
+- 在进行数值比较或计算时，需要注意数据类型之间的隐式转换，以免出现意外的结果。

+# 二进制类型（BINARY）
+
+## 概述
+
+在 Lakehouse 中，BINARY 类型用于存储二进制数据，适用于存储图像、音频、视频以及其他二进制文件。BINARY 类型能够确保数据的完整性和一致性，适用于各种场景。最大写入长度限制为 16 MB。批量、实时导入时会对字段进行长度校验。如果您导入的数据超过 16 MB，可以修改表的属性（Properties）来调整限制，例如将 BINARY 长度设置为 32 MB：
+```
+ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.binary.bytes"="33554432");
+```
+
+
+
+## 语法
+
+BINARY 类型的声明非常简单，只需在数据类型前加上关键字 `BINARY` 即可。例如：
+
+```sql
+CREATE TABLE binary_table (
+  id INT,
+  data BINARY
+);
+```
+
+## BINARY 常量值
+
+在 SQL 语句中，可以使用 `X` 前缀来构造 BINARY 常量值。例如：
+
+```sql
+SELECT X'4';
+```
+
+上述语句将返回一个字节序列 `[4]`。`X` 后跟的 `num` 是一个或多个十六进制字符，范围从 0 到 F，支持大写或小写。例如：
+
+```sql
+SELECT X'A413F';
+```
+
+将返回 `[0a 41 3f]`。
+
+## 转换函数
+
+Lakehouse 提供了多种函数来处理 BINARY 类型的数据，包括：
+
+1. `CAST()` 函数：将其他类型的数据转换为 BINARY 类型。
+2. `BASE64()` 函数：将二进制数据转换为 BASE64 编码的字符串。
+3. `UNBASE64()` 函数：将 BASE64 编码的字符串转换为二进制数据。
+4. `BINARY()` 函数：将字符串转换为 BINARY 类型的字节流。
+
+## 约束限制
+* BINARY 类型最大存储长度为 16 MB。
+
+## 示例
+
+以下是一些使用 BINARY 类型和相关函数的示例：
+
+1. 创建一个包含 BINARY 类型列的表：
+
+```sql
+CREATE TABLE binary_table (
+  id INT,
+  data BINARY
+);
+```
+
+2. 向表中插入数据：
+
+```sql
+INSERT INTO binary_table (id, data) VALUES (1, X'1');
+```
+
+3. 将字符串转换为 BINARY 类型并插入到表中：
+
+```sql
+INSERT INTO binary_table (id, data)
+SELECT col1, BINARY(col2)
+FROM values(1, 'guan') AS data(col1, col2);
+```
+
+4. 查询表中的数据：
+
+```sql
+SELECT data FROM binary_table;
+```
+
+5. 使用 `CAST()` 函数将字符串转换为 BINARY 类型：
+
+```sql
+SELECT CAST('ClickZetta' AS BINARY);
+```
+
+将返回 `[43 6c 69 63 6b 5a 65 74 74 61]`。
+
+6. 使用 `base64()` 和 `unbase64()` 函数进行编码和解码：
+
+```sql
+SELECT base64('ClickZetta');
+```
+
+将返回 `Q2xpY2taZXR0YQ==`，然后使用 `unbase64()` 函数进行解码：
+
+```sql
+SELECT cast(unbase64('Q2xpY2taZXR0YQ==') as string);
+```
+
+将返回原始字符串 `ClickZetta`。

+# 云器 Lakehouse 图像解析最佳实践
+
+## 引言
+
+在数据驱动的时代，图像数据已成为企业数据资产的重要组成部分。云器 Lakehouse 通过集成先进的图像识别和向量检索技术，为企业提供了一套完整的图像数据管理和分析解决方案。本文将通过一个美食图像识别的实战案例，详细介绍如何在云器 Lakehouse 中构建端到端的图像解析系统。
+
+## 1. 关键产品功能
+
+* **多模态存储**：支持图像文件、向量数据、结构化元数据的统一管理
+* **外部函数**（EXTERNAL FUNCTION）：无缝调用 AI 模型进行图像识别和向量化
+* **向量检索**：原生支持 1024 维向量存储和相似度计算
+
+## 2.实战案例：美食图像识别系统
+
+### 2.1 创建数据表结构
+
+首先，我们需要创建一个包含向量字段的表来存储图像信息：
+
+```sql
+-- 创建美食图像识别数据表
+CREATE    TABLE IF NOT EXISTS dish_images (
+          id BIGINT NOT NULL PRIMARY KEY IDENTITY (1),
+          url STRING NOT NULL COMMENT '图片的原始URL地址',
+          file_name STRING NOT NULL COMMENT '图片文件名',
+          image_content STRING COMMENT '使用fc_image_to_text提取的菜品信息',
+          image_vector VECTOR (FLOAT, 1024) COMMENT '使用fc_gen_emmbeding生成的图片向量',
+          created_at TIMESTAMP DEFAULT current_timestamp() COMMENT '创建时间'
+          )
+          COMMENT '美食图片识别数据表';
+
+```
+
+### 2.2 批量上传图像到 VOLUME
+
+云器 Lakehouse 的 VOLUME 功能提供了文件管理能力。以下示例展示如何从 URL 批量下载并上传图像。您可以从下方网址下载图片到本地，再通过 [Lakehouse JDBC 客户端](connect-with-cli.md) 将文件 PUT 到 USER VOLUME 中：
+
+[图片地址](http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood1.jpg)（可通过变换结果中的数字下载更多图片）
+
+```sql
+-- 注意：PUT命令需要通过 JDBC 客户端执行，不能在 SQL 编辑器中直接运行
+-- 从URL批量下载并上传图像到 USER VOLUME
+PUT 
+    '/User/Downloads/RecognizeFood1.jpg',
+    '/User/Downloads/RecognizeFood2.jpg',
+    '/User/Downloads/RecognizeFood3.jpg' 
+TO USER VOLUME SUBDIRECTORY 'dish_images';
+
+-- 查看上传的文件
+LIST USER VOLUME SUBDIRECTORY 'dish_images';
+```
+
+### 2.3 利用函数识别图片
+
+利用云函数实现图像的自动识别和向量化：
+
+```sql
+-- 插入单条记录，调用云函数进行图像识别和向量生成
+INSERT INTO dish_images (url, file_name, image_content, image_vector)
+VALUES 
+(
+    'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood1.jpg',
+    'RecognizeFood1.jpg',
+    -- 调用图像识别函数
+    public.fc_image_to_text('dish_recognition', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood1.jpg'),
+    -- 生成图像向量（注意：向量维度必须匹配）
+    CAST(public.fc_gen_emmbeding('multimodal', '', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood1.jpg') AS VECTOR(FLOAT, 1024))
+);
+
+-- 批量插入多条记录
+INSERT INTO dish_images (url, file_name, image_content, image_vector)
+VALUES 
+('http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood2.jpg', 
+ 'RecognizeFood2.jpg',
+ public.fc_image_to_text('dish_recognition', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood2.jpg'),
+ CAST(public.fc_gen_emmbeding('multimodal', '', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood2.jpg') AS VECTOR(FLOAT, 1024))
+),
+('http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood3.jpg', 
+ 'RecognizeFood3.jpg',
+ public.fc_image_to_text('dish_recognition', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood3.jpg'),
+ CAST(public.fc_gen_emmbeding('multimodal', '', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood3.jpg') AS VECTOR(FLOAT, 1024))
+);
+```
+
+### 2.4 向量相似度搜索
+
+实现基于图像内容的相似度搜索：
+
+```sql
+-- 查找与目标图像最相似的菜品
+WITH target_vector AS (
+    SELECT CAST(public.fc_gen_emmbeding('multimodal', '', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood5.jpg') AS VECTOR(FLOAT, 1024)) as vec
+)
+SELECT 
+    d.id,
+    d.file_name,
+    d.url,
+    d.image_content,
+    cosine_distance(d.image_vector, t.vec) as similarity_score
+FROM dish_images d, target_vector t
+ORDER BY similarity_score ASC
+LIMIT 5;
+
+-- 基于已有图像查找相似图像
+SELECT 
+    d1.file_name as source_image,
+    d2.file_name as similar_image,
+    d2.image_content,
+    cosine_distance(d1.image_vector, d2.image_vector) as similarity_score
+FROM dish_images d1, dish_images d2
+WHERE d1.file_name = 'RecognizeFood1.jpg'
+  AND d1.id != d2.id
+ORDER BY similarity_score ASC
+LIMIT 5;
+```
+
+## 3.高级应用场景
+
+### 3.1 多维度图像分析
+
+结合结构化查询和向量搜索，实现复杂的分析需求：
+
+```sql
+-- 查找特定类别的图像
+SELECT 
+    id,
+    file_name,
+    image_content
+FROM dish_images
+WHERE image_content LIKE '%海鲜%' 
+   OR image_content LIKE '%鱼%'
+   OR image_content LIKE '%虾%'
+   OR image_content LIKE '%蟹%'
+ORDER BY id;
+
+-- 分析菜品识别结果的置信度分布
+SELECT 
+    file_name,
+    image_content,
+    -- 提取置信度（需要根据实际JSON格式调整）
+    CAST(SUBSTRING(image_content,

+# 通过Bluepipe实现Oracle数据库到云器Lakehouse的实时数据同步
+
+## 方案介绍
+
+30 多年来，Oracle 一直在关系数据库和数据仓库领域占有重要地位。随着 Exadata、Exalytics、Exalogic、SuperCluster 和 12c Database 等集成系统的推出，存储和计算的紧密集成使得能够使用本地基础设施更快地处理大量数据。然而，数据的数量、速度和种类急剧增加，而云为现代数据分析带来了更多可能性。例如，通过将计算与存储分离，云器Lakehouse实现了新一代的云数据平台，以share-nothing数据架构实现了计算和存储的自动即时扩展。
+![](.topwrite/assets/image_1718854284202.png)
+
+## 方案优势
+
+Bluepipe支持从Oracle到云器Lakehouse的实时数据同步。特别是在多实例、多表的复杂数据库环境中，Bluepipe实现了自动化同步，极大降低了人工配置同步作业的复杂度和工作量。对于数万张表的源数据库，Bluepipe能够做到自动配置同步任务。
+
+### 开箱即用，10 分钟完成配置
+
+* `Bluepipe`几乎可以运行在任何`Linux`系统中，支持`x86`和`arm`芯片；常见的机架式服务器、笔记本电脑，甚至树莓派都可以用来部署；
+* 极简的配置过程，默认参数即可达到最佳性能。
+
+### 全、增量一体化，无需运维干预
+
+* 全量同步与增量同步深度协同，几乎无需日常运维操作；
+* 高效的数据比对与热修复技术，始终保证数据一致性；
+* 高度鲁棒的`Schema Evolution`。
+
+### 推数据，而不是暴露端口
+
+* `Bluepipe`与您的数据库一起部署在您的内网，无需对外暴露端口；
+* 弹性`buffer size`技术，在`吞吐(Throughput)`和`延迟(latency)`之间自动平衡。
+
+## Oracle链路的独特优势
+
+`Bluepipe`基于`Oracle LogMiner`实现对变更数据的捕捉。与此同时，在以下几个方面做了深度优化：
+
+### 对DDL行为的深度兼容
+
+在`LogMiner`默认策略下，当发生`DDL`行为后，相关表上后续的`DML`操作均无法正确解析，从而导致无法正确捕捉到变更。
+`Bluepipe`维护了字典文件的自动构建策略，保证表结构变更后仍然能捕捉到正确的增量数据。
+
+### 大事务优化
+
+`Oracle Redo Log`中记录了完整的事务(`Transaction`)过程，而业务上通常仅希望拿到`commit` 之后的数据，因此，需要在传输过程中使用`buffer`来暂存尚未`commit`的变更记录。
+`Bluepipe`基于独特的内存管理技术，单节点上也能轻松应对千万量级的大事务。
+`Oracle 12.2`版本之后，对表名、字段名的最大长度支持到了 128 字节。 但因为种种原因，`LogMiner`对于无`OGG LICENSE`的实例，至今仍不支持对包含长名称的表的 DML 解析，详情参考[官方文档](https://docs.oracle.com/en/database/oracle/oracle-database/19/sutil/oracle-logminer-utility.html)。
+`Bluepipe`基于高效的流批融合技术，全面支持了此种情况下的增量数据捕捉与投递。
+
+### 适配支持`RAC`架构
+
+## 同步效果
+
+LAG：10秒左右
+同步速度：20000行/秒

+
+### 在Oracle数据库创建表
+
+```
+CREATE TABLE metabase.people_with_pk (
+    id INTEGER PRIMARY KEY,
+    age INTEGER,
+    name VARCHAR(32),
+    create_date DATE DEFAULT GETDATE()
+);
+
+CREATE TABLE metabase.employees (
+    employee_id INTEGER  PRIMARY KEY,
+    first_name VARCHAR(50),
+    last_name VARCHAR(50),
+    hire_date DATE,
+    salary INTEGER,
+    department_id INTEGER,
+    email VARCHAR(100),
+    phone_number VARCHAR(20),
+    address VARCHAR(200),
+    job_title VARCHAR(100),
+    manager_id INTEGER,
+    commission_pct DECIMAL,
+    birth_date DATE,
+    marital_status VARCHAR(10),
+    nationality VARCHAR(50),
+    create_date DATE DEFAULT GETDATE()
+);
+CREATE TABLE  metabase.departments (
+    department_id INTEGER  PRIMARY KEY,
+    department_name VARCHAR(100),
+    location VARCHAR(200),
+    manager_id INTEGER,
+    created_date DATE,
+    description VARCHAR(500),
+    budget INTEGER,
+    status VARCHAR(20),
+    contact_person VARCHAR(100),
+    phone_number VARCHAR(20),
+    email VARCHAR(100),
+    website VARCHAR(200),
+    start_date DATE,
+    end_date DATE,
+    num_employees INTEGER,
+    create_date DATE DEFAULT GETDATE()
+);
+```
+
+### 在Bluepipe新建同步作业
+
+请注意：
+
+1. 在选择来源时，目标表名 `{namespace}/{table}` 中的 `{namespace}`，可以用你期望的schema名字来替代，比如 `bluepipe_oracle_staging`。
+2. 在设计环节，增量复制选择“使用CDC技术实时复制”。
+   新建同步作业成功后的效果如下图：
+   ![](.topwrite/assets/image_1718871018707.png)
+   新建作业会自动启动并开始全量数据同步，之后开始持续的增量数据实时同步。
+
+### 数据生成
+
+通过运行如下Python代码，向Oracle源表employees中实时插入数据：
+
+```
+import oracledb
+import random
+import time,datetime

+# CHAR
+`CHAR` 是一种固定长度的字符类型，其最大长度为 255。当字符长度不足指定的最大长度时，系统不会自动使用空格填充至最大长度。在进行字符串比较时，尾随空格并不会被考虑在内。
+
+## 语法
+```
+CHAR(N)
+```
+其中，`N` 表示字符类型 `CHAR` 的最大长度，范围为 1 到 255。
+
+
+
+## 示例
+1. 创建一个固定长度为 5 的 `CHAR` 类型：
+```
+CREATE TABLE char_t(col CHAR(5));
+```
+
+2. 插入一个长度不足的字符串：
+```
+SELECT CHAR(10) 'abcd';
+```
+结果将返回一个长度为 10 的字符串，例如：`'abcd'`
+
+3. 插入一个长度超过指定长度的字符串：
+```
+SELECT cast( 'abcdef' as char(3))
+```
+结果将返回一个长度为 3 的字符串，例如：`'abc'`（仅取前 3 个字符）
+
+4. CHAR 在比较时，忽略尾随空格：
+```
+SELECT cast('abc' as char(5)) = cast('abc' as char(10));
+```
+结果将返回 `true`，因为尾随空格在比较时会被忽略。
+
+## 注意事项
+- 在进行字符串比较时，应考虑到 `CHAR` 类型的尾随空格会被忽略的特性。
+- 根据实际需求，合理选择 `CHAR` 类型与 `VARCHAR` 类型。如果数据长度固定或变化范围较小，可使用 `CHAR` 类型以提高性能；反之，如果数据长度变化较大，建议使用 `VARCHAR` 类型以节省存储空间。

+      * lineSep：行分隔符，默认值为"\n"。最多支持长度为 2 的字符，例如：`lineSep='$'`
+      * quote：用于转义包含特殊字符的字段。默认值为双引号“"“，例如：* `quote = '"'`：使用双引号作为转义字符。 `quote = '\''`：使用单引号作为转义字符。
+      * header：是否解析表头，默认为 false。布尔类型，例如：`header='true'`
+      * timeZone：配置时区，没有默认值。用于指定文件中时间格式的时区。例如：`timeZone = 'Asia/Shanghai'`
+      * escape：用于转义已加引号的值中的特殊字符，仅支持单字节字符。默认值为”\“，例如：`'escape'=r'\'`。转义字符用于解释数据文件中字段分隔符或换行符的特殊含义。如果某一行以反斜杠结尾，则该字符会转义为文件格式选项中指定的换行符或回车符（`lineSep`）。因此，加载操作会将此行和下一行视为一行数据。如果不需要这种转义行为，可以将转义字符设置为其他字符
+      * nullValue: 用于判定什么样的内容应该是 Null，默认值为 \`""\`，例如 \`'nullValue'='\\\N'\`或者\`'nullValue'=r'\N'\`为了避免在不确定何时需要转义的情况下手动处理转义字符，Lakehouse支持在字符串前添加`r`前缀，表示字符串中的转义字符不会被转义，可以直接输入到表达式中运行。
+      * multiLine: 是否有跨行的 csv 记录，默认值为 `false`，如果有这样的记录，需要配置 `multiLine='true'`
+      * writebom: BOM（Byte Order Mark）是位于文件开头的特殊标记字符（U+FEFF），在CSV文件中主要作用包括：明确声明文件使用UTF-8/UTF-16等Unicode编码需要配置和 帮助软件自动识别编码格式，避免解码错误。Windows版Excel依赖BOM识别UTF-8编码文件\*无BOM时中文/日文等非ASCII字符可能显示为乱码。推荐使用场景导出的CSV文件需要在**Windows Excel**中打开。`writebom=true`

+          sep='|'
+          compression='gzip'
+      );
+      ```
+        * headerQuotingStyle：默认值为 "needed"，可选值 "none"。"needed" 始终给header两边加引号，"none"不加引号，遇到控制字符时报错。
+        * dataQuotingStyle：默认值为 "needed"，可选值 "none-unsafe"。"needed"始终给header两边加引号，"none-unsafe" 始终不加引号，且遇到控制字符不报错（不符合 CSV 规范但我们支持）
+
+    
+    * JSON格式支持的参数:

+# 使用COPY INTO导出文件
+
+将表或查询结果导出到指定路径。您可以将一张表或查询结果导出为文件并保存到 Volume 的指定路径。请注意，如果指定路径下已存在同名文件，则该文件将会被覆盖。
+
+注意事项
+
+* **默认文件名**：Lakehouse 导出时，默认文件名是相同的。因此，如果您多次运行导出操作并且指定了相同的子目录（SUBDIRECTORY），新文件将覆盖上次导出的文件。
+* **避免覆盖**：为了防止意外覆盖现有文件，请确保每次导出时使用唯一的文件名或子目录。
+
+# 语法
+
+```SQL
+---语法
+COPY INTO { VOLUME external_volume_name | TABLE VOLUME table_name  | USER VOLUME }  
+SUBDIRECTORY '<path>'
+FROM { [schema.]<table_name> | ( <query> ) }
+FILE_FORMAT = ( TYPE = { CSV  | PARQUET | JSON }  [ formatTypeOptions ]  ) 
+[ copyOptions ]
+```
+
+## **参数说明**
+
+* **COPY INTO**：表示向目录中追加数据。
+
+* **VOLUME**：支持 `external_volume_name`，具体介绍参考[Volume介绍](datalake_volume.md)。
+  * `external_volume_name`：客户指定的外部存储位置，云器仅保留路径元信息。支持的存储产品有：阿里云 OSS、腾讯云 COS、亚马逊云 S3。创建过程可以参考[CONNECTION创建](Datalake_StorageConnection.md)和[VOLUME创建](datalake_volume_object.md)。
+  * **Table Volume**：Lakehouse内部存储，与内表对象共同存储于指定Schema路径下。
+  * **User Volume**：用户账号关联的文件存储区域，Workspace User默认对该区域具备管理权限。每个Workspace都默认拥有一个具备管理权限的User Volume。

+
+***
+
+* **SUBDIRECTORY**：指定子路径，该参数必须填写。例如：`subdirectory 'month=02'`
+
+* **FROM**：支持直接导出表中数据，或直接编写查询语句（query）。
+
+```SQL
+ --直接指定表
+ COPY INTO VOLUME my_volume SUBDIRECTORY 'dau_unload/'
+ FROM TABLE birds
+ file_format = (type = CSV);
+ --将SQL结果集导出
+ COPY INTO VOLUME my_volume SUBDIRECTORY 'dau_unload/'
+ FROM  (select * from birds limit 1)
+ file_format = (type = CSV);
+```
+
+* **formatTypeOptions**：文件格式，支持 CSV、TEXT、PARQUET、JSON。其中 JSON 导出的格式参考 [JSON LINE](https://jsonlines.org/)。
+
+* CSV 格式支持的参数：
+  * sep：列分隔符，默认为 ”,“。最多支持长度为 1 的字符，例如：`sep=','`
+  * compression：配置文件压缩格式。支持的压缩格式有：gzip/zstd/zlib。例如：`compression='gzip'`
+  * lineSep：行分隔符，默认值为"\n"。最多支持长度为 2 的字符，例如：`lineSep='$'`
+  * quote：设置用于转义引号值的单个字符。默认值为双引号“"”，例如：`quote='"'`
+  * header：是否解析表头，默认为 false。布尔类型，例如：`header='true'`
+  * timeZone：配置时区，没有默认值。用于指定文件中时间格式的时区。例如：`timeZone = 'Asia/Shanghai'`
+  * escape：用于转义已加引号的值中的引号，默认值为“\”，例如：`escape='\'`
+  * nullValue：用于判定什么样的内容应为 Null，默认值为 \`""\`，例如 `nullValue='\\\N'` 或者 `nullValue=r'\N'`。使用 `r` 可以不需要转义字符，参考[正则转译](regexp-statement.md)。
+  * multiLine：是否有跨行的 CSV 记录，默认值为 `false`。如果有这样的记录，需要配置 `multiLine='true'`。
+  ```SQL
+  --指定分隔符为｜和压缩
+  COPY INTO VOLUME my_volume  SUBDIRECTORY 'dau_unload/'
+  FROM TABLE birds
+  file_format = (
+      type= CSV
+      sep='|'
+      compression='gzip'
+  );
+  ```
+
+* JSON 格式支持的参数：
+  * compression：源文件/目标文件是否压缩，默认不压缩，配置如 `'compression'='gzip'`
+
+  ```SQL
+    COPY INTO VOLUME my_volume  SUBDIRECTORY 'dau_unload/'

+# 创建BLOOMFILTER索引
+
+## 功能
+
+布隆过滤器（Bloom Filter）是一种概率型数据结构，用于判断一个元素是否属于某个集合。本功能允许用户在表中创建布隆过滤器索引，以提高查询效率。具体介绍参考 [Bloomfilter Index](bloomfilter-summary.md)。
+
+## 语法
+
+```
+CREATE BLOOMFILTER INDEX [IF NOT EXISTS] index_name ON TABLE 
+[schema].table_name(column_name)
+[COMMENT 'comment']
+[PROPERTIES ('key'='value')]
+```
+
+**bloomfilter**：索引类型，使用布隆过滤器算法。
+
+**index_name**：要创建的索引名称，需位于指定的schema下，且在同一schema下不能重复。
+
+**schema**：可选参数，用于指定表的schema名称。
+
+**table_name**：要创建索引的表名称。
+
+**column_name**：要创建索引的列名称，目前仅支持单列索引。
+
+**COMMENT**：可选参数，用于添加关于索引的描述信息。
+
+**PROPERTIES**：可选参数，Lakehouse保留属性，方便之后扩展添加属性。当前可选参数如下：
+| 参数名称 | 描述 |
+| :---| :----|
+| analyzer |   将字符串按固定长度分割为 ngram |
+| n | ngram的长度， 例如：当 ngram 长度设为4时，字符串 "Lakehouse" 将被索引为：Lake hous e ' |
+
+## 示例
+```
+CREATE TABLE IF NOT EXISTS demo_bloomfilter_index (
+col_1 string,
+col_2 string,
+col_3 string,
+index idx_bf (col_1) bloomfilter,
+index idx_ngram_bf (col_2) bloomfilter properties ('analyzer' = 'ngram', 'n' = '10')
+) USING parquet;
+
+CREATE BLOOMFILTER INDEX IF NOT EXISTS idx_ngram_bf1 
+ON TABLE demo_bloomfilter_index(col_3)
+COMMENT 'ngram 索引'
+properties ('analyzer' = 'ngram', 'n' = '3');
+
+SHOW INDEX FROM demo_bloomfilter_index;
+```
+
+## 参考文档
+
+* [构建索引](build-inverted-index.md)
+* [删除索引](DROP-INDEX.md)
+* [列出所有索引](SHOW-INDEX.md)
+* [查看索引详情](DESC-INDEX.md)
+
+## 使用注意事项
+
+1. BLOOMFILTER INDEX 添加完成后，只有新写入的数据才会生效。旧数据不会生效。如果旧数据需要生效，必须重写数据。
+2. 一张表可以创建多个布隆过滤器索引。
+3. 类型限制：不支持 INTERVAL、STRUCT、MAP、ARRAY 等类型。如果尝试使用不支持的类型，系统将报错。
+
+## 使用说明
+
+[BLOOMFILTER INDEX使用说明](bloomfilter-summary.md)
+
+## 示例
+
+1. 建表时指定 BLOOMFILTER 索引
+
+   ```
+   DROP TABLE IF EXISTS t;
+   CREATE    TABLE t (
+             order_id INT,
+             customer_id INT,
+             amount DOUBLE,
+             order_year string,
+             order_month string,
+             INDEX order_id_index (order_id) BLOOMFILTER COMMENT 'BLOOMFILTER'
+             );         
+   INSERT INTO t

+# CONNECTION
+
+在Lakehouse中，CONNECTION对象扮演着至关重要的角色。它负责存储第三方服务的身份认证信息和访问管理凭据，以实现数据处理过程中对敏感信息的保护。通过使用CONNECTION，用户无需将身份认证信息以明文形式暴露，从而确保数据安全。此外，CONNECTION还支持STS（Security Token Service）认证方式，允许跨账号授权访问Lakehouse外部的服务，从而进一步提高了数据访问的灵活性和安全性。
+
+## CONNECTION的类型
+
+根据其用途和连接的外部服务类型，CONNECTION对象主要分为以下三种类型：
+
+1. [创建API Connection](<create-api-connection.md>)：这种类型的CONNECTION主要用于存储和保护第三方应用服务的身份认证信息。通过API Connection，Lakehouse可以安全地通过API调用与这些服务进行交互。目前，API Connection支持的外部服务包括阿里云的函数计算FC和腾讯云的云函数服务。API Connection通常与Remote Function结合使用，以便在Lakehouse中远程调用这些服务。
+2. [创建Storage Connection](<create-storage-connection.md>)：Storage Connection主要用于存储第三方存储服务的身份认证信息，使得Lakehouse能够安全地访问和管理这些存储服务中的数据。目前支持的外部存储服务包括阿里云的对象存储OSS、腾讯云COS和AWS S3。
+3. [创建Catalog Connection](<create-catalog-connection.md>)：在数据湖架构中，Catalog Connection是一种关键组件，用于将数据湖与外部的元数据存储（例如Hive Metastore）关联起来。通过创建 Catalog Connection，用户可以实现元数据的统一管理和访问，从而直接读取存储在外部系统中的数据。Lakehouse目前只支持连接Hive。

+Lakehouse 引入了一项强大的功能，即通过 `EXTERNAL SCHEMA` 将外部数据库映射到 Lakehouse，使得用户能够在不迁移数据的情况下，直接在 Lakehouse 中查询外部数据。这一功能极大地提升了跨数据源操作和查询的便利性，为用户提供了更加灵活的数据集成解决方案。
+
+# 使用限制
+
+* 目前，云器 Lakehouse 的外部模式映射功能支持以下外部数据源：
+  * Hive on OSS（阿里云对象存储服务，支持读取和写入）
+  * Hive on COS（腾讯云对象存储服务，支持读取和写入）
+  * Hive on S3（AWS 对象存储服务，支持读取和写入）
+  * Hive on HDFS（Preview，请联系 Lakehouse 支持，仅支持读取）
+  * Databricks Unity Catalog
+* 同时支持写入和读取。写入格式支持 Parquet、ORC、Text 文件格式。
+
+# 创建 Hive External Schema
+
+## 语法
+
+### 创建存储连接
+
+首先，您需要创建一个存储连接，以连接到外部对象存储服务。
+
+```SQL
+CREATE STORAGE CONNECTION if not exists catalog_storage_oss
+    type OSS
+    ACCESS_ID='LTAIxxxxxxxxxxxx'
+    ACCESS_KEY='T8Gexxxxxxmtxxxxxx'
+    ENDPOINT='xxx';
+```
+
+### 创建 Hive Catalog 连接
+
+接着，创建一个 Catalog 连接，指向 Hive 元数据存储服务（Hive Metastore）。
+
+```SQL
+CREATE CATALOG CONNECTION if not exists connection_name
+    type hms
+    hive_metastore_uris='metastore_uris'
+    storage_connection='storage_connection';
+```
+### 创建 External Schema
+
+最后，创建一个 External Schema，将外部数据源映射到 Lakehouse。
+
+```SQL
+CREATE EXTERNAL SCHEMA if not exists schema_name
+    CONNECTION connection_name
+    options(SCHEMA='hive_database_name');
+```
+* `connection`：必选参数，指定Catalog Connection的名称。
+* `SCHEMA`：可选参数，用于映射 Hive 的数据库名称。如果未指定，Lakehouse 将默认使用创建的 `schema_name` 名称与 Hive 中的数据库进行自动映射。
+
+
+### 案例
+
+**案例一：Hive on OSS**
+
+* 创建存储连接
+
+```SQL
+CREATE STORAGE CONNECTION if not exists catalog_storage_oss

+# 物化视图创建与使用
+
+## 功能介绍
+
+根据现有表的查询，在当前指定的Schema中创建一个新的物化视图，并用查询数据填充视图。
+
+有关更多详细信息，请参阅[物化视图](MATERIALIZEDVIEW.md)。
+
+## 语法说明
+
+```SQL
+CREATE [OR REPLACE | IF NOT EXISTS] MATERIALIZED VIEW mv_name
+[ (column_list) ] 
+[CLUSTERED BY (column_name)]
+[PARTITIONED BY (column_name)]
+[ COMMENT view_comment ] 
+[BUILD DEFERRED|BUILD IMMEDIATE]
+[refreshOption]
+[DISABLE QUERY REWRITE]
+AS <query>;  
+
+refreshOption ::=
+    REFRESH 
+    [START WITH timestamp_expr]  [interval_time] VCLUSTER vcname
+```
+
+**必需参数**
+
+1. mv_name: 指定物化视图名称。
+2. AS query：物化视图所包含的查询语句。
+
+**可选参数**
+
+1. IF NOT EXISTS:可选，如果指定的物化视图名字存在，系统不会报错，但是物化视图不会创建成功。不能和OR REPLACE同时使用
+
+2. OR REPLACE:在传统数据库中，此选项用于在同一个事务内用新对象替换旧对象，并删除旧对象的数据。但在Lakehouse中，为了支持物化视图的增加、删除和修改操作，我们保留了数据以及元数据权限信息。这意味着，即使在修改表结构或SQL逻辑时，原有数据也不会丢失。此功能特别适用于添加或删除列、调整SQL处理逻辑以及变更数据类型。请注意您修改时必须使用BUILD DEFERRED ...DISABLE QUERY REWRITE语法，该语法则会禁用物化视图重写功能，如果用户不是简单的 删除列 / 添加列 添加列定义：只能是从表一路经由SELECT透传的，不能参与任何会影响其他列的计算例如 join key, group key 等
+则在 Create Or Replace 发生后，REFRESH任务会退化为一次全量刷新。如果您想体验增量计算功能请使用[DYNAMIC TABLE](dynamic-table-introduce.md)

+     AS select i,j+1 from mv_base_a;
+     +-------------+-----------+---------+
+     | column_name | data_type | comment |
+     +-------------+-----------+---------+
+     | i           | int       |         |
+     | j_dd        | int       | test    |
+     +-------------+-----------+---------+
+     --当存在列运算表达式使用别名方式
+     CREATE  MATERIALIZED VIEW mv
+     AS select i,j+1 as j_add from mv_base_a;
+     +-------------+-----------+---------+
+     | column_name | data_type | comment |
+     +-------------+-----------+---------+
+     | i           | int       |         |
+     | j_add       | int       |         |
+     +-------------+-----------+---------+
+   ```
+
+3. partitioned by (\<col> ):指定分区，将\<column\_list>的列作为分区，分区是一种通过在写入时将相似的行分组在一起来加快查询速度的方法。使用分区可以达到数据裁剪，优化查询。
+
+   ```SQL
+      CREATE MATERIALIZED VIEW mv
+      (i,j_dd comment 'test')
+      partitioned by(j_dd)
+      AS select i,j+1 from mv_base_a;
+   ```
+
+4.CLUSTERED BY：可选，指定Hash Key。Lakehouse将对指定列进行Hash运算，将数据根据Hash值分散到各个数据分桶中。为了避免数据倾斜和热点，并提高并行执行效果，建议选择取值范围大、重复键值少的列作为Hash Key。通常在进行join操作时会有明显效果。建议在数据量大的场景下使用CLUSTERED BY，一般按照一个桶的大小在128MB到1GB之间。如果没有指定分桶，默认为256个buckets。
+
+* SORTED BY：可选，指定Bucket内字段的排序方式。建议SORTED BY和CLUSTERED BY保持一致，以获得更好的性能。当指定SORTED BY子句后，行数据将按照指定的列进行排序。
+  ```SQL
+  --创建分桶表
+  CREATE MATERIALIZED VIEW mv (i, j_dd COMMENT 'test') 
+  CLUSTERED BY (j_dd) INTO 16 BUCKETS AS
+  SELECT    i,
+            j + 1
+  FROM      mv_base_a;
+  --创建分桶并指定排序
+  CREATE MATERIALIZED VIEW mv
+  (i, j_dd COMMENT 'test')
+  CLUSTERED BY (j_dd) SORTED BY (j_dd)  INTO 16 BUCKETS  
+  AS
+  SELECT    i,
+            j + 1
+  FROM      mv_base_a;
+  ```
+
+5. COMMENT:指定物化视图的注释信息
+
+6. BUILD DEFERRED:这是一种物化视图的创建方式。与立即生成数据的`BUILD IMMEDIATE`不同，`BUILD DEFERRED`允许在创建物化视图时不立即生成数据。默认值是BUILD IMMEDIATE，当使用CREATE OR REPLACE语法时必须是BUILD DEFERRED
+
+7. refreshOption可选，刷新选项
+   * START WITH timestamp\_exp 指定开始时间，支持指定一个时间戳表达式，如果不写 START WITH 则从当前时间开始刷新
+     * `timestamp_expression`返回结果是一个标准的时间戳类型的表达式，TIMESTAMP AS OF指定的最早时间戳取决[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。如果未指定则使用当前时间戳的版本数据，例如：
+       \* `'2023-11-07 14:49:18'`，即可以强制转换为时间戳的字符串。
+       \* `cast('2023-11-07 14:49:18 Asia/Shanghai' as timestamp)`。
+       \* `current_timestamp() - interval '12' hours`。
+       \* 本身就是时间戳或可强制转换为时间戳的任何其他表达式。
+     ```
+     --指定第二天开始刷新,刷新时间间隔20个小时
+     CREATE MATERIALIZED VIEW mydt
+          (i,j)
+          REFRESH
+          START WITH current_timestamp() +INTERVAL '1' DAY
+          INTERVAL '20' HOUR
+         vcluster test_alter AS
+         SELECT    *
+         FROM      mv_base_a;
+     ```
+   * interval\_time指定时间间隔，支持[时间间隔类型interval](INTERVAL.md)，如果不写interval\_time，写了 START WITH 则只定时刷新一次START WITH 指定的时间。interval\_time时间间隔如下

+| ----------------------------------- | ---------------------------- | --------------------------------------------------------- |
+| INTERVAL '\[+ \| -]' DAY            | 仅指定DAY间隔                     | INTERVAL '1' DAY表示1天                                      |
+| INTERVAL '\[+ \| -]' HOUR           | 仅指定HOUR间隔                    | INTERVAL '23' HOUR表示23小时                                  |
+| INTERVAL '\[+ \| -]' MINUTE         | 仅指定MINUTE间隔                  | INTERVAL '59' MINUTE表示59分钟                                |
+| INTERVAL '\[+ \| -]' SECOND         | 仅指定SECOND间隔                  | INTERVAL '59.999' SECOND表示59.999秒                         |
+| INTERVAL '\[+ \| -] ' DAY TO HOUR   | 同时指定DAY和HOUR间隔               | INTERVAL '1 23' DAY TO HOUR表示1天23小时                       |
+| INTERVAL '\[+ \| -] ' DAY TO MINUTE | 同时指定DAY、HOUR和MINUTE间隔        | INTERVAL '1 23:59' DAY TO MINUTE表示1天23小时59分钟              |
+| INTERVAL '\[+ \| -] ' DAY TO SECOND | 同时指定DAY、HOUR、MINUTE和SECOND间隔 | INTERVAL '1 23:59:59.999' DAY TO SECOND表示1天23小时59分59.999秒 |
+
+day：取值范围为\[0, 2147483647]。 hour：取值范围为\[0, 23]。minute：取值范围为\[0, 59]。second：取值范围为\[0, 59.999999999]。
+
+* INTERVAL最小值是1分钟，可以用 60 SECOND 或者1 MINUTE 来表示
+  * INTERVAL支持带引号或者不带引号，以下表示是等价的：
+    \*  INTERVAL "60 SECOND"
+    \*  INTERVAL ‘60 SECOND’
+    \* INTERVAL 60 SECOND
+  * INTERVAL支持的单位：SECOND，MINUTE，HOUR，DAY
+  * INTERVAL单位不区分大小写，HOUR、hour是等价的
+
+* 在 `refreshOption` 中指定计算集群。自动刷新会消耗资源，因此需要明确指定计算集群。如果未指定，将默认使用当前会话的计算集群。您可以通过 `SELECT current_vcluster()` 查看当前会话的计算集群。
+
+  ```SQL
+  CREATE MATERIALIZED VIEW my_mv (i, j)
+  REFRESH   interval '1' MINUTE vcluster test AS
+  SELECT    *
+  FROM      mv_base_a;
+  ```
+
+8. DISABLE QUERY REWRITE：这是指物化视图不支持查询重写的特性。查询重写是指数据库优化器在对物化视图的基表进行查询时，自动判断是否可以通过查询物化视图来得到结果，如果可以，则避免了聚集或连接操作，直接从已经计算好的物化视图中读取数据。
+
+## 注意事项
+
+* 物化视图的增量刷新是基于基表的历史版本。历史版本取决于[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。此参数定义了在被删除数据被保留的时间长度，Lakehouse默认保留数据一天。根据您的业务需求，您可以通过调整 `data_retention_days` 参数来延长或缩短数据的保留周期。请注意，调整数据保留周期可能会影响存储成本。延长保留周期会增加存储需求，从而可能增加相关的费用。
+
+## 示例
+
+### 示例1 简单物化视图
+
+本示例展示了如何创建一个表 (`inventory`)，以及如何基于该表创建一个物化视图 (`mv_inventory_basic`)。接着，插入了一条数据，然后从物化视图中选择数据、刷新物化视图，最后再次从物化视图中选择数据，从而观察手工刷新物化视图的效果。
+
+```SQL
+-- 创建一个名为 inventory 的表，包括 product_ID、wholesale_price 和 description 字段
+CREATE TABLE inventory (product_ID INTEGER, wholesale_price FLOAT, description VARCHAR);
+
+-- 如果物化视图 mv_inventory_basic 不存在，则创建该视图，选择 inventory 表中的 product_ID、wholesale_price 和 description 字段
+CREATE MATERIALIZED VIEW IF NOT EXISTS mv_inventory_basic AS
+SELECT product_ID, wholesale_price, description
+FROM inventory;
+
+-- 向 inventory 表中插入一条数据：
+INSERT INTO inventory (product_ID, wholesale_price, description) VALUES 
+    (1, 1.00, 'cog');
+
+-- 从物化视图 mv_inventory_basic 中选择 product_ID 和 wholesale_price 字段，查看插入数据后的视图内容
+SELECT product_ID, wholesale_price FROM mv_inventory_basic;
+
+-- 刷新物化视图 mv_inventory_basic，以确保视图内容与基表保持一致
+REFRESH MATERIALIZED VIEW mv_inventory_basic;
+
+-- 再次从物化视图 mv_inventory_basic 中选择 product_ID 和 wholesale_price 字段，查看刷新后的视图内容
+SELECT product_ID, wholesale_price FROM mv_inventory_basic;
+```
+
+以上 SQL 语句展示了如何创建和使用物化视图。在实际操作中，物化视图可以显著提高查询性能，尤其是在涉及复杂计算或大量数据时。通过刷新物化视图，确保视图数据与源表数据保持一致，以提供最新的查询结果。**注意：由于在创建物化视图时没有使用调度参数因此这里是进行手动刷新**。
+
+### 示例2 带列列表和注释的物化视图
+
+```SQL
+CREATE MATERIALIZED VIEW mv_inventory_with_comment
+(product_ID, wholesale_price, description)
+COMMENT 'This is a materialized view for inventory'
+AS
+SELECT product_ID, wholesale_price, description
+FROM inventory;
+```
+
+### 示例3 带分区和聚簇的物化视图
+
+```SQL
+CREATE MATERIALIZED VIEW mv_inventory_partitioned_clustered
+
+(product_ID, wholesale_price, description)
+
+PARTITIONED BY (product_ID)
+
+CLUSTERED BY (product_ID)
+
+AS
+
+SELECT product_ID, wholesale_price, description
+
+FROM inventory;
+```
+
+### 示例4 带刷新选项和虚拟计算集群的物化视图
+
+```SQL
+CREATE MATERIALIZED VIEW mv_inventory_refresh
+
+REFRESH START WITH current_timestamp INTERVAL '1 HOUR' VCLUSTER default
+
+AS
+
+SELECT product_ID, wholesale_price, description
+
+FROM inventory;
+```
+
+修改带有刷新选项的物化视图的刷新周期：
+
+```SQL
+CREATE OR REPLACE MATERIALIZED VIEW mv_inventory_refresh
+
+BUILD DEFERRED
+
+REFRESH START WITH current_timestamp INTERVAL '1 MINUTE' VCLUSTER default
+
+DISABLE QUERY REWRITE
+
+AS
+
+SELECT product_ID, wholesale_price, description
+
+FROM inventory;
+```
+
+查看修改结果：
+
+```SQL
+DESC EXTENDED mv_inventory_refresh;
+```
+
+可以看到refresh\_interval\_second的值已经是60了，表名修改刷新周期成功。
+对于按周期自动刷新的物化视图，如果需要暂停或者恢复自动刷新，请参考：
+[修改物化视图](alter-materialzied-view.md)
+
+### 示例5 综合示例
+
+```SQL
+CREATE MATERIALIZED VIEW mv_inventory_full
+(product_ID, wholesale_price, description)
+COMMENT 'Materialized view with partition, clustering, and refresh options'
+PARTITIONED BY (product_ID)
+CLUSTERED BY (wholesale_price)
+REFRESH START WITH current_timestamp INTERVAL '1 day' VCLUSTER 'default_ap'
+AS
+SELECT product_ID, wholesale_price, description
+FROM inventory;
+
+```
+
+### 示例6：创建物化视图并添加注释
+
+重建MATERIALIZED VIEW可以复用上次结果。场景包含加列，可以重用上次的mv，添加的新的列老数据显示为null
+
+**案例**
+
+```SQL
+CREATE    TABLE employees (
+          emp_id int,
+          emp_name varchar,
+          dept_id int,
+          salary int
+          );
+
+-- 创建一个测试表，存储部门的信息
+CREATE    TABLE departments (
+          dept_id int,
+          dept_name varchar,
+          LOCATION varchar
+          );
+
+-- 插入一些数据到 employees 表
+INSERT    INTO employees

+          (40, '人事部', '深圳');
+
+-- 创建一个物化视图，存储每个部门的员工数量和平均工资
+CREATE materialized VIEW dept_emp_stats AS
+SELECT    d.dept_id,
+          d.dept_name,
+          d.location,
+          count(e.emp_id) AS emp_count,
+          avg(e.salary) AS avg_salary
+FROM      departments d
+JOIN      employees e ON d.dept_id = e.dept_id
+GROUP BY  d.dept_id,
+          d.dept_name,

+
+--给departments加上一列
+ALTER     TABLE departments ADD COLUMN col1 string;
+
+INSERT    INTO employees
+VALUES    (1001, 'aa', 10, 5000);
+
+--使用create or replace语法加列。加列为了避免重算会重用上次结果，可以看到直接在job profile使用的上次mv的表
+CREATE OR       
+REPLACE materialized VIEW dept_emp_stats build deferred disable QUERY rewrite AS

+# 功能
+
+本文介绍了如何创建自定义角色以及对现有角色进行替换的 SQL 语法。
+# Workspace角色管理
+## 语法
+
+```SQL
+CREATE [OR REPLACE] ROLE [IF NOT EXISTS] role_name COMMENT '';
+```
+
+- **CREATE**: 创建一个新的角色。
+- **OR REPLACE** (可选): 如果已存在同名角色，则替换该角色。
+- **IF NOT EXISTS** (可选): 如果指定的角色名称不存在，则创建新角色。如果角色已存在，不会报错，也不会创建新角色。
+- **role_name**: 指定新角色的名称。请注意，角色名称不能与系统预定义的角色名称相同。
+- **COMMENT** (可选): 为角色添加注释，可以留空或提供有关角色的信息。
+
+## 示例
+
+1. 创建一个名为 `simple_role` 的自定义角色：
+
+   ```SQL
+   CREATE ROLE simple_role;
+   ```
+
+2. 创建一个名为 `admin_role` 的角色，并为其添加注释：
+
+   ```SQL
+   CREATE ROLE admin_role COMMENT '拥有高级权限的角色';
+   ```
+
+3. 替换已存在的 `existing_role` 角色：
+
+   ```SQL
+   CREATE OR REPLACE ROLE existing_role;
+   ```
+
+4. 创建一个名为 `new_role` 的角色，如果该角色已存在，则不会创建新角色：
+
+   ```SQL
+   CREATE ROLE IF NOT EXISTS new_role;
+   ```
+
+# Instance Role 管理
+
+LakeHouse 支持在 **实例粒度（Instance-Level）** 创建角色，实现跨工作空间（Workspace）的统一权限管控，满足多团队协作场景下的精细化访问控制。需要INSTANCE_ADMIN可以执行此操作
+
+## 语法说明
+
+```SQL
+-- 创建 Instance Role（若不存在）
+CREATE INSTANCE ROLE IF NOT EXISTS <role_name>;
+-- 删除 Instance Role（如果存在）
+DROP INSTANCE ROLE IF EXISTS <role_name>;
+-- 查看所有 Instance Role
+SHOW INSTANCE ROLES;
+```
+
+#### 示例
+
+```SQL
+
+DROP INSTANCE ROLE IF EXISTS inst_role;
+
+CREATE INSTANCE ROLE IF NOT EXISTS inst_role;
+
+SHOW INSTANCE ROLES;
+```

+### 功能描述
+
+`CREATE SCHEMA` 语句旨在创建一个新的数据模式（SCHEMA）。通过定义模式名称和可选的描述性注释，用户能够在数据管理系统中构建一个新的逻辑数据分组，从而实现数据的有序组织和高效管理。
+
+### 语法格式
+
+```Plaintext
+CREATE SCHEMA [ IF NOT EXISTS ] schema_name [ COMMENT 'comment' ];
+```
+
+### 参数详解
+
+- `schema_name`: 指明新创建的数据模式名称。
+- `IF NOT EXISTS`: 非必选参数，用于防止在数据模式已存在的情况下产生错误。
+- `COMMENT`: 为新数据模式添加描述性注释，有助于理解模式的用途和内容。
+
+### 使用示例
+
+1. 创建一个名为 `customer_data` 的新数据模式，并为其添加注释 "客户相关数据"：
+
+   ```SQL
+   CREATE SCHEMA customer_data COMMENT '客户相关数据';
+   ```
+
+2. 若需避免因数据模式已存在而产生错误，可以使用 `IF NOT EXISTS` 参数：
+
+   ```SQL
+   CREATE SCHEMA IF NOT EXISTS sales_data COMMENT '销售相关数据';
+   ```
+
+3. 创建一个具有中文注释的数据模式：
+
+   ```SQL
+   CREATE SCHEMA financial_data COMMENT '财务数据';
+   ```

+## CREATE VIEW
+
+本命令用于基于对一个或多个现有表的查询结果，在当前或指定的 SCHEMA 中创建一个新的视图。视图是一种虚拟表，它提供了对查询结果的访问，而无需直接操作底层数据表。
+
+## 语法
+
+```SQL
+CREATE [ OR REPLACE ] VIEW [ IF NOT EXISTS ] [schema_name.]view_name
+    [ (column_name comment '' [, ...]) ]
+    [ COMMENT 'comment' ]
+    AS query;
+```
+
+## 参数说明
+
+- **OR REPLACE**：此选项用于替换任何同名的已存在视图（如果存在）。需要注意的是，它不能与 `IF NOT EXISTS` 选项同时使用。使用此选项相当于先对现有的视图执行 `DROP VIEW` 操作，然后创建一个具有相同名称的新视图。
+- **column_name**：指定新视图中的列名称。如果需要为新视图中的列指定别名或添加注释，可以使用此参数。
+- **COMMENT**：为新创建的视图添加注释信息。这有助于其他用户了解视图的用途和结构。
+- **query**：用于生成视图内容的 SQL 查询语句。
+
+## 使用示例
+
+1.  创建一个名为 `myview` 的视图，包含来自 `mytable` 表的 `col1` 和 `col2` 列：
+
+   ```SQL
+   CREATE VIEW myview AS
+   SELECT col1, col2 FROM mytable;
+   ```
+
+2.  创建一个名为 `myview` 的视图，并为其指定列别名和注释：
+
+   ```SQL
+   CREATE VIEW myview (col1_alias comment 'col1_alias', col2_alias comment 'col2_alias')
+   COMMENT 'This is my view with aliased columns'
+   AS
+   SELECT col1 AS col1_alias, col2 AS col2_alias FROM mytable;
+   ```
+
+3.  创建一个名为 `myview` 的视图，只包含满足特定条件的记录：
+
+   ```SQL
+   CREATE VIEW myview AS
+   SELECT col1, col2, col3
+   FROM mytable
+   WHERE col1 > 100;
+   ```
+
+4.  使用 `OR REPLACE` 选项替换已存在的同名视图：
+
+   ```SQL
+   CREATE OR REPLACE VIEW myview AS
+   SELECT col1, col2, col4
+   FROM mytable;
+   ```
+
+5.  在指定的 SCHEMA 中创建视图：
+
+   ```SQL
+   CREATE VIEW schema_name.myview AS
+   SELECT col1, col2
+   FROM schema_name.mytable;
+   ```

+# CREATE EXTERNAL FUNCTION
+
+外部函数（EXTERNAL FUNCTION）是云器 Lakehouse 提供的强大功能，允许您通过 Python 和 Java 语言创建自定义函数（UDF），并通过远程云服务执行。这种灵活性使您能够扩展 Lakehouse 的计算能力，处理复杂的业务逻辑。支持以下云服务平台执行外部函数：
+
+* 阿里云函数计算（FC）
+* 腾讯云云函数服务
+* AWS Lambda 服务
+
+支持开发语言：
+
+* Python 3.10
+* Java 8
+
+对于以下三种不同类型的自定义函数：
+
+* UDF（用户自定义函数）：处理输入行中的一个或多个列，并为每一行返回单个结果值。
+* UDAF（用户自定义聚合函数）：对多行数据进行聚合计算，返回单个结果值。
+* UDTF（用户自定义表函数）：接收一个或多个输入参数，返回多行多列的结果集。
+
+Python 函数支持 UDF，Java 函数支持 UDF、UDAF 和 UDTF
+
+## EXTERNAL FUNCTION 创建主要流程
+
+* 用户开通云上的函数计算服务（如阿里云的函数计算FC）和对象存储服务
+
+* 将 EXTERNAL FUNCTION 执行代码、可执行文件、依赖的库、模型和数据文件，打包上传至对象存储
+
+* 授予云器 Lakehouse 操作上述服务和访问函数文件的权限
+
+* 用户执行连接和 EXTERNAL FUNCTION DDL 创建函数
+
+* 用户在云器 Lakehouse SQL 语句中使用函数
+
+* 云器 Lakehouse 根据提供的服务地址和认证信息发送 HTTP 请求调用运行函数
+
+* 云器 Lakehouse 获取响应信息返回结果
+
+## EXTERNAL FUNCTION 优势
+
+* 可以使用 EXTERNAL FUNCTION 调用外部丰富的数据处理能力，对传统 SQL 计算模型做补充。如可调用大语言模型（LLM）、图像、音视频等，补充 SQL 的非结构化数据处理能力
+* 可以直接访问外部网络，不受云器 Lakehouse 网络约束
+
+## 语法
+
+```SQL
+CREATE EXTERNAL FUNCTION [ IF NOT EXISTS ] [<database_name>.]<schema_name>.<function_name>
+  AS <class_name>
+  USING { FILE | JAR | ARCHIVE } = '<resource_uri>'[, ...]
+  CONNECTION = <api_connection_name>
+  WITH PROPERTIES ( '<property_name>' = '<property_value>'[, ...] )
+  [ COMMENT  '<comment_string>' ]
+```
+
+## 参数说明
+
+### 必选参数
+
+* `function_name`: 指定函数的名称。
+
+* `class_name`：对于 JAVA 函数，指 JAVA 函数的主类名；对于 Python 函数，为主类名和模块名的组合，例如，主程序文件为 `video_contents.py`，主类名为 `image_to_text`，AS 后的参数为 `'video_contents.image_to_text'`。
+
+* `api_connection_name`：指定连接函数计算的认证信息，具体请参考[创建连接](CREATECONNECTION.md)。
+
+* `resource_uri`：资源连接，指 EXTERNAL FUNCTION 运行所需的资源文件。需指定对应的文件地址，要求认证信息（API CONNECTION 或者内部 VOLUME）具有该文件的读取权限。您也可以指定内部 VOLUME 如 USER VOLUME 和 TABLE VOLUME 存放代码包，这样您无需再去开通云对象存储服务。虽然您可以使用内部 volume 存放函数程序包，但是您在创建 API CONNECTION 中的 code bucket 参数必须填写外部对象存储的 BUCKET 名称。
+  * **External** **Volume 格式地址**：`volume://[{workspace}.][{schema}.]{volume_name}/upper.jar`
+    * `workspace` 和 `schema` 是可选项，如果省略，将使用当前上下文默认值。
+  * **User Volume 格式地址**：`volume:user://~/upper.jar`
+    * `user` 表示使用 User Volume 协议。
+    * `~` 表示当前用户，为固定值。
+    * `upper.jar` 表示目标文件名。
+  * **Table Volume 格式地址**：`volume:table://[{workspace}.][{schema}.]{table_name}/upper.jar`
+    * `workspace` 和 `schema` 是可选项，如果省略，将使用当前上下文默认值。
+    * `table` 表示使用 Table Volume 协议。
+    * `table_name` 表示表名，需根据实际情况填写。
+    * `upper.jar` 表示目标文件名。
+
+* `WITH PROPERTIES`：指定函数的参数信息。
+  1. `remote.udf.api` - 指定运行时编译环境，支持两种选项：
+
+     * `python3.mc.v0`：当使用 Python UDF 时需要指定此选项
+     * `java8.hive2.v0`：当使用 JAVA Hive 风格 UDF 时需要指定此选项
+  2. `remote.udf.protocol` - 指定访问协议，默认值为`http.arrow.v0`，代表访问云函数的协议
+
+### 可选参数
+
+* `IF NOT EXISTS`：如果指定的函数已存在，则命令不会进行任何更改并返回一条指示函数存在的信息。如果不指定，函数存在时会直接返回错误信息。
+* `COMMENT`：指定注释信息。
+
+## 注意事项
+
+* 创建外部函数过程需要读取函数代码或可执行文件，可能需要较长时间。
+* 该命令无需启动 VC，因此不消耗 CRU。
+* 目前只支持 Java 和 Python 编程语言，支持的运行环境：Java 8 和 Python 3.10 版本

+
+# 使用示例
+
+## 阿里云创建 EXTERNAL FUNCTION
+
+**环境依赖**：系统已经创建 API CONNECTION，请参考 [API CONNECTION](create-api-connection.md)
+
+**步骤 1**：JAVA 语言编写 EXTERNAL FUNCTION，以下是实现大小写转换的示例代码：
+
+```java
+package com.example;
+
+import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
+import org.apache.hadoop.hive.ql.metadata.HiveException;
+import org.apache.hadoop.hive.ql.udf.generic.GenericUDF;
+import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspector;
+import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector;
+import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector.PrimitiveCategory;
+import org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory;
+
+import java.util.Locale;
+
+public class GenericUdfUpper extends GenericUDF {
+  @Override
+  public ObjectInspector initialize(ObjectInspector[] arguments) throws UDFArgumentException {
+    checkArgsSize(arguments, 1, 1);
+    checkArgPrimitive(arguments, 0);
+    if (((PrimitiveObjectInspector) arguments[0]).getPrimitiveCategory() != PrimitiveCategory.STRING) {
+      throw new UDFArgumentException("argument 0 requires to be string rather than " + arguments[0].getTypeName());
+    }
+    return PrimitiveObjectInspectorFactory.javaStringObjectInspector;
+  }
+
+  @Override
+  public Object evaluate(DeferredObject[] arguments) throws HiveException {
+    Object arg = arguments[0].get();
+    if (arg == null) {
+      return null;
+    }
+    return ((String) arg).toUpperCase(Locale.ROOT);
+  }
+
+  @Override
+  public String getDisplayString(String[] children) {
+    return "upper";
+  }
+}
+```
+
+编译代码生成 **Jar 包和其他依赖文件**，打包成 zip 压缩包
+
+**步骤 2**：上传函数程序包到指定路径
+如： `oss://hz-oss-lakehouse/functions/sentiment/UDF_code/my_upper.zip`
+函数主类：`com.clickzetta.my_upper`
+有两种方法上传文件到指定路径：
+
+* 通过 OSS 客户端直接上传
+* 在 Lakehouse JDBC 客户端（不支持 Lakehouse Web UI 使用 PUT 命令上传）通过 [PUT 命令](PUT.md) 将程序包上传至 [Volume 对象](datalake_volume.md)，并在创建函数 DDL 中引用 VOLUME 路径和上面创建的 API CONNECTION。例如：
+
+```SQL
+-- 上传文件到命名为 fc_volume 的 Volume对象：
+PUT './my_upper.zip' to volume fc_volume file '/udfs/my_upper.zip';
+
+-- 在创建函数时引用该 Volume 路径：
+create external function public.my_upper
+    AS 'com.clickzetta.my_upper' 
+    USING ARCHIVE 'volume://fc_volume/udfs/my_upper.zip' 
+    CONNECTION my_function_connection
+    WITH
+    PROPERTIES (
+        'remote.udf.api' = 'java8.hive2.v0'
+);
+```
+
+**步骤 3**：使用函数
+
+```SQL
+SELECT public.my_upper('a');
+```
+
+**说明**：
+
+如果您使用 USER VOLUME 替换**步骤 2** 中的 OSS 路径，USER VOLUME 为云器 Lakehouse 默认提供的个人文件存储空间（类似于操作系统的用户 HOME 目录）
+
+```SQL
+-- 查看 USER VOLUME
+SHOW USER VOLUME DIRECTORY;
+
+-- 上传文件至 USER VOLUME
+-- !!! 注意：
+-- 1. 需使用 Lakehouse JDBC 客户端工具执行 PUT 命令，文件路径为本地路径。
+-- 2. 必须使用包含依赖的 JAR 包
+PUT '/Users/nero/Downloads/udf/expudf-1.0-SNAPSHOT-jar-with-dependencies.jar' TO USER VOLUME;
+
+-- 删除已存在的函数定义（如有）
+DROP FUNCTION IF EXISTS public.eval_exp_internal_volume;
+
+-- 创建外部函数
+CREATE EXTERNAL FUNCTION public.eval_exp_internal_volume
+AS 'com.clickzetta.hive.udf.EvalExpUdf' 
+USING FILE 'volume:user://~/expudf-1.0-SNAPSHOT-jar-with-dependencies.jar' 
+CONNECTION udf_api_conn
+WITH PROPERTIES (
+    'remote.udf.api' = 'java8.hive2.v0'
+);
+
+-- 测试函数：返回字符串结果
+SELECT public.eval_exp_internal_volume(
+    named_struct('a', 1d, 'b', 4.3d, 'c', 3d), 
+    '(a+b)/c'
+).string_result;
+
+-- 测试函数：返回浮点数结果
+SELECT public.eval_exp_internal_volume(
+    named_struct('a', 1d, 'b', 4.3d, 'c', 3d), 
+    '(a+b)/c'
+).double_result;
+```

+# 用CTE方式对客户进行同类群组分析
+
+## CTE
+
+[CTE(Common Table Expression) ](WITH.md)，公用表表达式，它是在单个语句的执行范围内定义的临时结果集，只在查询期间有效。它可以自引用，也可在同一查询中多次引用，实现了代码段的重复利用。
+
+## 同类群组（Revenue Cohort）
+
+同类群组（Revenue Cohort）分析是对几个不同同类群组（即客户群）的分析，以更好地了解行为、模式和趋势。
+最常见的同类群组分析类型之一着眼于基于时间的同类群组，这些群组按特定时间范围对用户/客户进行分组。例如，一家公司可能希望了解其在 1 月份开始使用该产品或开始付款的客户与 2 月份的客户相比如何。
+基于细分的群组代表使用或购买特定产品或服务的客户群。例如，您可以根据用户每周登录您的应用的时间来细分用户。
+另一种类型的群组是基于规模的群组，它按货币价值对客户进行细分。这是游戏行业（免费用户与鲸鱼用户）或 SaaS 世界中的常见做法，通过他们的 LTV 或计划对客户进行细分。
+对于本文的其余部分，我们将只关注实施基于时间的收入群组分析。
+队列分析所需的数据，在开始队列分析之前，需要以下数据：
+\*     与购买数据相关联的收入数据
+\*     用户的唯一标识符，例如客户 ID 或帐户 ID
+\*     每个用户的初始开始日期，无论是注册日期还是第一次付款。
+
+## 数据说明
+
+本文所使用的数据来自云器Lakehouse的共享样例数据，可以直接按照如下方式直接使用:
+
+```
+select * from clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore limit 10;
+```
+
+![](.topwrite/assets/image_1718761578596.png)
+
+## 分析步骤
+
+1. 临时结果集user\_cohorts：首先，我们想将用户分到群组中——在这种情况下，我们想按他们的Order Week 。
+2. 临时结果集order\_Week：接下来我们要创建一个order\_month变量。例如，客户在首次付款后一个月进行的付款的值为order\_month2。创建一个order\_Week变量。例如，客户在首次付款后一周进行的付款的order\_Week值为 2。
+3. 临时结果集cohort\_size：进一步，我们现在可以汇总cohortMonth第一步中创造的收入。这将使我们能够创建我们的rentention\_table.汇总cohortMonth第一步中创造的收入。这将使我们能够创建我们的rentention\_table.
+   构建分析模型如下：
+
+```
+WITH 
+eCommerce_LifeCycle_Order_Sequence AS (
+SELECT event_date,
+       user_id,
+       ROW_NUMBER() OVER (PARTITION BY user_id ORDER BY event_date ASC) AS customer_order_sequence,
+       LAG(event_date) OVER (PARTITION BY user_id ORDER BY user_id ASC) AS previous_order_date,
+       MIN(event_date) AS first_order_date,
+       MAX(event_date) AS last_order_date

+         ELSE previous_order_date
+       END AS previous_order_date,
+       DATEDIFF(event_date,previous_order_date) AS days_between_orders,

+         WHEN days_between_orders > 30 THEN '沉睡客户'

+       END AS customer_life_cycle,
+       customer_order_sequence,
+       previous_order_date,
+       CASE
+         WHEN days_between_orders IS NULL THEN 0
+         ELSE days_between_orders
+       END AS days_between_orders,
+       first_order_date,
+       last_order_date
+FROM eCommerce_LifeCycle_Time_Between_Orders)
+select * from eCommerce_LifeCycle;
+```
+
+运行上述SQL代码，结果如下：
+![](.topwrite/assets/image_1718761957078.png)
+
+也可以通过以下方式，可以将结果直接写入到目标表中：
+
+```
+DROP TABLE if exists eCommerce_User_Cohort;
+
+CREATE TABLE if not exists eCommerce_User_Cohort
+
+AS
+
+--将用户分到群组中。在本例中，我们想按他们的Order Date
+
+with user_cohorts as (

+

+
+FROM retention_table r
+
+LEFT JOIN cohort_size s on r.cohortWeek=s.cohortWeek 
+
+WHERE r.cohortWeek IS NOT NULL
+
+ORDER BY 1, 3;
+
+```
+
+## 回顾：物理表的方式
+
+不使用CTE，而是将每一个子查询的结果都落成物理表，则整个处理过程如下：
+
+1. 根据每个客户的升序订单日期创建特定于每个客户 ID 的订单序列列。这就是ROW\_NUMBER 分析函数在下面的查询中所做的。
+2. 创建一个新列，为客户 ID 插入先前的订单日期，以便在以后的代码块中用于计算订单之间的时间段。这就是LAG 分析函数在以下查询中所做的。
+   –请注意语句末尾的“Group By”order\_date 和 customer\_id 列。这很重要，因为客户可以在同一天拥有多个具有不同订单 ID 的订单。
+
+```
+DROP TABLE if exists eCommerce_LifeCycle_Order_Sequence;
+CREATE TABLE eCommerce_LifeCycle_Order_Sequence 
+AS
+SELECT event_date,
+       user_id,
+       ROW_NUMBER() OVER (PARTITION BY user_id ORDER BY event_date ASC) AS customer_order_sequence,
+       LAG(event_date) OVER (PARTITION BY user_id ORDER BY user_id ASC) AS previous_order_date,
+       MIN(event_date) AS first_order_date,
+       MAX(event_date) AS last_order_date
+FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore
+WHERE event_type = 'purchase'
+GROUP BY event_date,
+         user_id;
+```
+
+针对上表运行子查询以计算 order\_date 和 previous\_order\_date 列之间的天数，您将看到创建新列 days\_between\_orders 的 DATE\_DIFF 函数会发生这种情况。
+
+```
+DROP TABLE if exists eCommerce_LifeCycle_Time_Between_Orders;
+CREATE TABLE eCommerce_LifeCycle_Time_Between_Orders 
+AS
+SELECT event_date,
+       user_id,
+       customer_order_sequence,
+       CASE
+         WHEN previous_order_date IS NULL THEN event_date
+         ELSE previous_order_date
+       END AS previous_order_date,
+       DATEDIFF(event_date,previous_order_date) AS days_between_orders,
+       first_order_date,
+       last_order_date
+FROM eCommerce_LifeCycle_Order_Sequence;
+```
+
+下一个查询使用CASE 语句创建一个附加的 customer\_life\_cycle 列，以根据 days\_between\_orders 列指示订单是来自新客户、活跃客户还是已失效客户。在此示例中，如果订单发生在距上一个订单 1 到 365 天之间的任何时间，则客户被视为活跃客户；如果先前订单超过 365 天，则客户被视为已失效。这具有高度的业务特定性，因此您的可能会有所不同。
+
+```
+DROP TABLE if exists eCommerce_LifeCycle;
+CREATE TABLE eCommerce_LifeCycle 
+AS
+SELECT event_date,
+       user_id,
+       CASE
+         WHEN customer_order_sequence = 1 THEN '新客户'
+         WHEN days_between_orders > 0 AND days_between_orders < 30 THEN '活跃客户'
+         WHEN days_between_orders > 30 THEN '沉睡客户'
+         ELSE '未知'
+       END AS customer_life_cycle,
+       customer_order_sequence,
+       previous_order_date,
+       CASE
+         WHEN days_between_orders IS NULL THEN 0
+         ELSE days_between_orders
+       END AS days_between_orders,
+       first_order_date,
+       last_order_date
+FROM eCommerce_LifeCycle_Time_Between_Orders;
+```
+
+```
+select * from eCommerce_LifeCycle limit 100;
+```

+# **外部 AI 函数**：创建 Embedding 函数
+
+目标：利用阿里云百炼平台的 Embedding 函数，将文本和图片文件数据向量化，并实现以图搜图的场景。效果如下：
+
+![](.topwrite/assets/image_search.png)
+
+> 注意：完成本示例，需要您：
+>
+> 1. 已安装 Docker（主要是为了保证开发环境与云上运行函数的环境一致）
+> 2. 拥有阿里云账号，并开通百炼平台的 API-KEY。参考 [阿里云百炼](https://www.aliyun.com/product/bailian)
+> 3. 已经创建好 API 连接。参考：创建 [API 连接](create-api-connection.md)
+
+### Step 1：准备开发环境
+
+1. **安装 Docker**：确保您的本地已安装 Docker：<https://www.docker.com/>
+
+2. **拉取 Docker 镜像**。在本地命令行终端（如 macOS 的 Terminal）执行：
+
+   ```
+   [Local]# docker pull quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779
+   ```
+
+3. **启动 Docker 容器**：该容器基于 `manylinux2014_x86_64` 镜像，并配置为使用 Python 3.10 环境。
+
+   ```
+   [Local]# docker run -it --name cz_func --env PATH="/opt/python/cp310-cp310/bin:$PATH" quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779 bash
+   ```
+
+> 如果容器已经停止，可以用以下命令启动并进入：
+>
+> 1. **启动容器**：
+>
+> ```
+> # docker start cz_func
+> ```
+>
+> 2. **进入容器**：
+>
+> ```
+> # docker exec -it cz_func bash
+> ```
+
+4. 在 /root 目录下创建文件夹 `embeddings`
+
+```
+[root@docker root]# cd /root ; mkdir embeddings 
+[root@docker embeddings]# cd embeddings
+[root@docker embeddings]# touch gen_embeddings.py
+```
+
+5. `cz_llm.py` 中的程序代码如下：

+        dim=args.dim
+    )
+    print(result)
+```
+
+### Step 2：下载第三方库
+
+程序依赖第三方包：`openai` 需要进行下载（其余为 Python 内置库，`os`、`json` 为 Python 内置库，无需下载。`cz.udf ` 在创建函数时系统会默认添加）。
+
+在开发环境的命令行终端执行：
+
+```
+[root@docker embeddings]# pwd
+/root/embeddings
+
+[root@docker embeddings]# pip install openai -t .
+```
+
+此时目录结构类似于：
+
+![](.topwrite/assets/vector2.jpeg)
+
+### Step 3：本地调试
+
+需要对以下 3 行代码进行修改，因为当前环境还没有加载 `cz.udf` 库：
+
+```
+...
+2 #from cz.udf import annotate   # 注释掉
+...
+6 #@annotate("*->string")  # 注释掉
+...
+```
+
+其中 API\_KEY 是阿里云百炼平台的 API-KEY，需要您注册阿里云账号，登录后在这里获取：[阿里云百炼](https://bailian.console.aliyun.com/?spm=5176.12818093_47.console-base_search-panel.dtab-product_sfm.60852cc9WIq2Db\&scm=20140722.S_sfm._.ID_sfm-RL_%E5%A4%A7%E6%A8%A1%E5%9E%8B%E6%9C%8D%E5%8A%A1%E5%B9%B3%E5%8F%B0%E7%99%BE%E7%82%BC%E6%8E%A7%E5%88%B6%E5%8F%B0-LOC_console_console-OR_ser-V_4-P0_0\&tab=api#/api)
+
+注释掉上面两行之后，保存并退出编辑脚本。请将下面的 image\_url 和 api\_key 替换为真实的参数并执行：
+
+```
+[root@docker embeddings]# export PYTHONPATH="${_PWD}:${_PWD}/lib"
+[root@docker embeddings]# python gen_embeddings.py \
+    --model_type multimodal \
+    --input_string ${image_url} \
+    --api_key ${api_key} \
+    --model_name multimodal-embedding-v1
+```
+
+### Step 4：打包上传
+
+打包之前，请将上面注释掉的两行代码取消注释。
+
+```
+...
+2 from cz.udf import annotate   # 去掉注释
+...
+8 @annotate("*->string")  # 去掉注释
+```
+
+执行打包命令前，请确保当前目录为程序目录（本示例为 `/root/cz_llm`）。
+
+```
+[root@docker embeddings]# pwd
+/root/embeddings
+[root@docker embeddings]# zip -rq ../embeddings.zip ./
+[root@docker embeddings]# ls ../
+```
+
+> 提示：如果您的环境没有 zip 命令，请使用 `yum install zip` 尝试安装。安装过程中遇到问题，请参考附录“**安装工具时报错**”。
+
+您会发现在 `/root ` 目录下有一个 `cz_llm.zip` 文件，将这个文件拷贝到 Lakehouse USER VOLUME 中：
+
+在 Docker 宿主机中执行：
+
+```
+[Local]# docker cp cz_func:/root/embeddings.zip ~/Downloads
+```
+
+现在 `cz_llm.zip ` 在宿主机的用户 `Downloads` 目录下
+
+我们使用 Lakehouse JDBC 客户端（请参考 [Lakehouse JDBC 客户端](connect-with-cli.md)），将文件上传（put）到 Lakehouse USER VOLUME 中：
+
+```
+PUT '/Users/derekmeng/Downloads/embeddings.zip' to USER VOLUME;
+```
+
+![](.topwrite/assets/image2.jpeg)
+
+### Step 5：创建并使用函数：
+
+本步骤依赖您提前创建好 API Connection，创建过程请参考：[API Connection ](create-api-connection.md)
+
+```
+CREATE EXTERNAL FUNCTION public.fc_embeddings
+AS 'gen_embeddings.get_embeddings'
+USING ARCHIVE 'volume:user://~/embeddings.zip'
+connection sg_fc_api_conn
+WITH PROPERTIES (
+'remote.udf.api' = 'python3.mc.v0'
+)
+COMMENT 'Examples:
+For text: text <input_string> <api_key> <model_name> <dim>
+For multimodal:multimodal <input_string> <api_key> <model_name>';
+```
+
+```
+# Verify
+select public.fc_embeddings('multimodal', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood5.jpg', '${api_key}', 'multimodal-embedding-v1');
+```
+
+执行效果：
+
+![](.topwrite/assets/images.jpeg)
+
+接下来的步骤是实现以图搜图功能的核心步骤。该查询接收一个图片 URL，将其向量化，然后与数据表（`food_images_data_vec`）中的所有图片向量进行比较。表 `food_images_data_vec` 的内容如下：
+
+![](.topwrite/assets/image_search.jpeg)

+
+### 4. 数据库
+
+在下面的部分中，请在 config.json 文件中填写不同的参数，以连接到您的 Lakehouse 环境。
+
+```python
+import pandas as pd
+import json
+from clickzetta.zettapark.session import Session
+import clickzetta.zettapark.functions as F
+import warnings
+
+warnings.filterwarnings("ignore", category=FutureWarning)
+
+# 从配置文件读取连接参数
+with open('config/config.json', 'r') as config_file:
+    config = json.load(config_file)
+
+schema = config['schema']
+vcluster = config['vcluster']
+
+print("Connecting to Lakehouse.....\n")
+
+# 创建会话
+session = Session.builder.configs(config).create()
+
+session.sql(f"CREATE SCHEMA IF NOT EXISTS {schema}").collect()
+session.sql(f"CREATE VCLUSTER IF NOT EXISTS {vcluster} VCLUSTER_SIZE=1 VCLUSTER_TYPE = GENERAL").collect()
+
+print(session.sql("SELECT current_instance_id(), current_workspace(),current_workspace_id(), current_schema(), current_user(),current_user_id(), current_vcluster()").collect())
+
+print("\nConnected！...\n")
+```
+
+### 5. 表
+
+此演示包含 2 张表：
+
+* CREDIT\_FILES：此表包含当前文件上的信用情况以及贷款是否正在偿还或在偿还信用方面是否存在实际问题。此数据集将用于历史分析并构建机器学习模型，以对新申请进行评分。
+
+* CREDIT\_REQUESTS：此表包含银行需要根据 ML 算法批准的新信用请求。
+
+#### 5.1 CREDIT\_FILES 表
+
+运行以下命令后，请登录到您的 Lakehouse 环境，确保表已创建。它应该有 2.9K 行。
+
+```python
+credit_files = pd.read_csv('data/credit_files.csv')
+credit_files.columns = credit_files.columns.str.lower()
+session.sql("drop table if exists CREDIT_FILES").collect()
+session.write_pandas(credit_files,"CREDIT_FILES",auto_create_table='True', quote_identifiers=False)
+```
+
+```
+<clickzetta.zettapark.table.Table at 0x7fe58538e990>
+```
+
+```python
+credit_df = session.table("CREDIT_FILES")
+credit_df.schema
+```
+
+```

+## 使用 Zeetapark for Python 进行信用评分
+
+在此笔记本中，我们将使用 [Zettapark](https://www.clickzetta.com/documents) Python API 进行信用卡评分演示。
+
+在此场景中，Zettabank 希望利用其现有的信用文件来分析当前的信用状况，即贷款是否正在顺利偿还，或者是否存在任何延迟/违约情况。
+
+基于当前的信用状况，Zettabank 希望基于数据集构建一个机器学习信用评分算法，以便能够自动评估贷款是否应该被批准或拒绝。
+
+### 先决条件
+
+请在运行此演示之前运行信用评分演示设置笔记本。
+
+### 1. 数据探索
+
+在此部分，我们将探索现有信用的数据集。
+
+#### 1.1 打开 Lakehouse 会话
+
+```python
+import json
+
+
+import pandas as pd
+from clickzetta.zettapark import *
+from clickzetta.zettapark.functions import *
+```
+
+```python
+# 从配置文件读取连接参数
+with open('config/config.json', 'r') as config_file:
+    config = json.load(config_file)
+
+
+schema = config['schema']
+vcluster = config['vcluster']
+
+
+print("Connecting to Lakehouse.....\n")
+
+
+# 创建会话
+session = Session.builder.configs(config).create()
+
+
+session.sql(f"CREATE SCHEMA IF NOT EXISTS {schema}").collect()
+session.sql(f"CREATE VCLUSTER IF NOT EXISTS {vcluster} VCLUSTER_SIZE=1 VCLUSTER_TYPE = GENERAL").collect()
+
+
+print(session.sql("SELECT current_instance_id(), current_workspace(),current_workspace_id(), current_schema(), current_user(),current_user_id(), current_vcluster()").collect())
+
+
+print("\nConnected！...\n")
+```
+
+#### 1.2 探索 Lakehouse 表中的数据
+
+```python
+credit_df = session.table("CREDIT_FILES")
+```
+
+```python
+credit_df.describe().toPandas()
+```
+
+```python
+credit_df.toPandas().info()
+```
+
+```

+```
+
+```python
+credit_df.toPandas()
+```
+
+#### 1.3 可视化数值特征
+
+从这个可视化中，我们可以看到一些有趣的特征：
+
+* 大多数信用请求的金额较小（<50k）
+* 大多数信用期限为20个月或更短。
+* 大多数申请人的信用评分很高。
+* 大多数申请人在 Zettabank 的信贷或储蓄账户中余额不多。
+* 大多数申请人年龄小于40岁。
+
+```python
+credit_df.toPandas().hist(figsize=(15,15))
+```
+
+```
+array([[<Axes: title={'center': 'credit_request_id'}>,
+        <Axes: title={'center': 'credit_amount'}>,
+        <Axes: title={'center': 'credit_duration'}>],
+       [<Axes: title={'center': 'installment_commitment'}>,
+        <Axes: title={'center': 'credit_score'}>,
+        <Axes: title={'center': 'checking_balance'}>],
+       [<Axes: title={'center': 'savings_balance'}>,
+        <Axes: title={'center': 'existing_credits'}>,
+        <Axes: title={'center': 'job_history'}>],
+       [<Axes: title={'center': 'age'}>,
+        <Axes: title={'center': 'num_dependents'}>,
+        <Axes: title={'center': 'residence_since'}>]], dtype=object)
+
+```

+:-: ![](.topwrite/assets/image_1742454418360.png =710)
+
+#### 1.4 可视化分类特征
+
+从这个可视化中，我们可以看到一些有趣的特征：
+
+* 大多数流行的信用请求与车辆购买或消费品相关。
+* 绝大多数贷款没有担保人，也没有共同申请人。
+* 大多数文件中的信用状况良好。
+* 大多数申请人是男性、外国工人、技术工人，拥有自己的房屋/公寓。
+* 更高金额的贷款（每个贷款类别的阈值不同）有更高的违约可能性。
+
+```python
+import matplotlib.pyplot as plt
+import seaborn as sns
+
+
+sns.set(style="darkgrid")
+
+
+fig, axs = plt.subplots(5, 2, figsize=(15, 30))
+df = credit_df.toPandas()
+sns.countplot(data=df, y="purpose", ax=axs[0,0])
+sns.countplot(data=df, x="other_parties", ax=axs[0,1])
+sns.countplot(data=df, x="credit_standing", ax=axs[1,0])
+sns.countplot(data=df, x="assets", ax=axs[1,1])

+sns.countplot(data=df, x="marital_status", ax=axs[3,1])
+sns.countplot(data=df, x="other_payment_plans", ax=axs[4,0])
+sns.stripplot(y="purpose", x="credit_amount", data=df, hue='credit_standing', jitter=True, ax=axs[4,1])
+plt.show()
+```
+
+:-: ![](.topwrite/assets/image_1742454469095.png =771)
+
+#### 1.5 通过 Zettapark API 运行查询
+
+我们可以使用 Zettapark API 运行查询以获取各种见解。例如，让我们尝试确定不同类别的贷款范围。我们可以通过检查 Lakehouse 查询历史来了解 Zettapark API 如何作为 SQL 推送。
+
+```python
+df_loan_status = credit_df.select(col("PURPOSE"),col("CREDIT_AMOUNT"))\
+                          .groupBy(col("PURPOSE"))\
+                          .agg([min(col("CREDIT_AMOUNT")).as_("MIN_CREDIT_AMOUNT"), max(col("CREDIT_AMOUNT")).as_("MAX_CREDIT_AMOUNT"), median(col("CREDIT_AMOUNT")).as_("MED_CREDIT_AMOUNT"),avg(col("CREDIT_AMOUNT")).as_("AVG_CREDIT_AMOUNT")])\
+                          .sort(col("PURPOSE"))
+df_loan_status.toPandas()
+```
+
+### 2. 数据转换和编码
+
+对于当前用例，为了将数据准备成机器学习所需的格式，我们需要将分类值编码成数值。
+
+为了实现这一点，我们可以利用 Zettapark Python API 进行编码。
+
+#### 2.1 准备机器学习的特征矩阵
+
+在此部分，我们将利用 Zettapark Python API 准备一个随机森林分类器模型的特征矩阵。
+
+```python
+from clickzetta.zettapark.functions import when
+
+
+feature_matrix = credit_df.select(
+    when(col("purpose") == "Consumer Goods", 1)
+    .when(col("purpose") == "Vehicle", 2)
+    .when(col("purpose") == "Tuition", 3)

+
+这是数据的样子：
+
+```python
+df.head()
+```
+
+### 3. 随机森林模型训练
+
+我们将使用 Python 中流行的 scikit-learn 机器学习库中的随机森林分类器模型。
+
+```python
+from sklearn.model_selection import train_test_split
+
+
+X_train, X_test, y_train, y_test = train_test_split(df.drop('credit_standing_code', axis=1), 
+                                                    df['credit_standing_code'], test_size=0.30)
+```
+
+```python
+from sklearn.ensemble import RandomForestClassifier
+
+
+rfc = RandomForestClassifier(n_estimators=100)
+rfc.fit(X_train, y_train)
+```
+
+### 4. 测试模型
+
+```python
+rfc_pred = rfc.predict(X_test)
+```
+
+```python
+from sklearn.metrics import classification_report, confusion_matrix
+
+
+print(classification_report(y_test,rfc_pred))
+```
+
+```
+              precision    recall  f1-score   support
+
+
+           0       0.99      0.87      0.92       275
+           1       0.94      1.00      0.97       607
+
+
+    accuracy                           0.96       882

+weighted avg       0.96      0.96      0.95       882
+```
+
+```python
+print(confusion_matrix(y_test,rfc_pred))
+```
+
+```
+[[238  37]
+ [  2 605]]
+```
+
+### 5. 在 Lakehouse 中进行推理
+
+在下面的例子中，我们希望处理 60 个待处理的信用请求，并对是否批准贷款进行评估。数据如下所示：
+
+```python
+df_cred_req = session.table("CREDIT_REQUESTS")
+```
+
+```python
+df_cred_req.toPandas()
+```
+
+```python
+df.info()
+```
+
+```
+<class 'pandas.core.frame.DataFrame'>
+RangeIndex: 2940 entries, 0 to 2939
+Data columns (total 20 columns):
+ #   Column                    Non-Null Count  Dtype
+---  ------                    --------------  -----
+ 0   purpose_code              2940 non-null   int64

+ 19  existing_credits          2940 non-null   int64
+dtypes: int64(20)
+memory usage: 459.5 KB
+```
+
+### 6. 开发评分函数
+
+当 Zettabank 接收信用请求时，我们希望编写一个函数，该函数可以通过任务调用，对传入的微批请求进行评分。
+
+Python 函数将首先使用 Zettapark API 构建模型的输入特征，以进行评分。
+
+```python
+from clickzetta.zettapark.functions import col, when
+
+
+def process_credit_requests_fn (session, credit_requests: str, credit_assessment: str) -> int:
+    
+    # 使用 Zettapark API 直接编码构建模型的输入特征。
+    df_cred_req = session.table(credit_requests).select( 
+                            col("CREDIT_REQUEST_ID"), col("PURPOSE"),
+                            when(col("PURPOSE") == "Consumer Goods", 1)

+# DATE
+
+`DATE` 类型用于表示日期，包括年（year）、月（month）和日（day）三个部分，但不包含时区信息。这种类型在处理与时间无关的数据时非常有用，例如记录用户的出生日期或事件的发生日期。
+
+## 语法
+
+```
+DATE [year]-[month]-[day]
+```
+
+- `year`: 年份，格式为四位数字，如 2023。
+- `month`: 月份，格式为两位数字，范围从 01 到 12，如 03。

+
+## 示例
+
+1. 插入当前日期：
+
+   ```sql
+   SELECT DATE('2023-03-15');
+   ```
+
+2. 从字符串转换为日期：
+
+   ```sql
+   SELECT DATE('2022-12-31');
+   ```
+
+3. 从当前时间获取日期部分：
+
+   ```sql
+   SELECT DATE(TIMESTAMP "2023-03-15 10:30:00");
+   ```
+
+4. 计算两个日期之间的差值：
+
+   ```sql
+   SELECT DATE('2023-04-01') - DATE('2023-03-15') AS DateDifference;
+   ```
+
+5. 将字符串转换为日期并进行比较：
+
+   ```sql
+   SELECT '2023-03-15' = DATE('2023-03-15') AS IsEqual;

+# DECIMAL
+`DECIMAL`类型用于表示具有特定最大精度和固定小数位数的数值。这种数据类型在处理金融、会计或其他需要精确数值计算的场景中非常有用，因为它可以避免浮点数运算的舍入误差。
+
+## 语法
+```
+DECIMAL(precision, scale)
+```
+* `precision`：表示数字的总位数，包括小数点两侧的位数。取值范围为1到38。
+* `scale`：表示小数点后的位数。取值范围为0到`precision`，且不能大于`precision`。
+
+## 示例
+```
+SELECT CAST(1234.56 AS DECIMAL(10, 2));  -- 结果为 1234.56
+SELECT CAST(123.456 AS DECIMAL(5, 3));   -- 结果为 null
+SELECT CAST(1.23 AS DECIMAL(4, 2));      -- 结果为 1.23
+SELECT CAST(1234 AS DECIMAL(6, 2));      -- 结果为 1234.00
+SELECT CAST(0.1234 AS DECIMAL(5, 4));    -- 结果为 0.1234
+```
+
+## 使用指南
+- 当`scale`为0时，表示数值为整数。
+- 当`precision`和`scale`的值相同时，表示数值为纯小数（即所有位数都在小数点后）。
+- 在进行数值转换时，如果转换结果超出了`DECIMAL`类型的范围，可能会发生数据截断或舍入。
+- 在比较`DECIMAL`类型的数值时，应考虑其精度和尺度，以避免因舍入误差导致的比较错误。
+
+## 注意事项
+- 在使用`DECIMAL`类型时，应根据实际需求合理选择`precision`和`scale`的值，以确保数值的精确性和计算的准确性。

+## 功能
+
+本命令用于查看视图的结构，包括视图的字段、类型等。
+
+## 语法
+
+```
+DESC[RIBE] [TABLE] [EXTENDED] view_name;
+```
+
+**参数说明**
+
+1. `DESC[RIBE]`：DESC和DESCRIBE可以互换使用，都表示查看视图结构的命令。
+2. `view_name`：指定需要查看结构的视图名称。
+
+可选参数：
+
+3. `EXTENDED`：加上此关键字后，可以展示包括定义视图的SQL语句.
+
+## 使用示例
+
+### 1. 查看视图结构（不使用EXTENDED关键字）
+
+```

+# DOUBLE
+
+## 概述
+
+64位二进制浮点型（DOUBLE）是一种用于表示实数的数值数据类型，它可以存储非常大或非常小的数值。在计算机系统中，64位浮点数遵循IEEE 754标准，提供了大约15到17位的有效数字精度。
+
+## 语法
+
+```
+DOUBLE
+```
+
+## 示例
+
+1. 返回正整数1的64位浮点表示：
+
+   ```
+   SELECT +1D;
+   ```
+
+2. 将整数-6转换为64位浮点数表示：
+
+   ```
+   SELECT CAST(-6 AS DOUBLE);
+   ```
+
+3. 返回科学计数法表示的数值1.99714E+13：
+
+   ```
+   SELECT 1.99714E+13;
+   ```
+
+4. 将字符串形式的浮点数转换为64位浮点数：
+
+   ```
+   SELECT CAST('123.456' AS DOUBLE);
+   ```
+
+5. 计算两个64位浮点数的和：
+
+   ```
+   SELECT CAST(123.45 AS DOUBLE) + CAST(678.91 AS DOUBLE);
+   ```
+
+6. 比较两个64位浮点数的大小：
+
+   ```
+   SELECT CAST(123.456 AS DOUBLE) > CAST(122.345 AS DOUBLE);
+   ```
+
+7. 计算一个64位浮点数的平方根：
+
+   ```
+   SELECT SQRT(CAST(16 AS DOUBLE));
+   ```
+
+## 注意事项
+- `FLOAT`或`DOUBLE`。这是因为浮点数在计算机中的表示方式可能会导致精度损失，从而在进行比较和关联操作时产生不准确的结果。

+# 删除索引
+
+## 简介
+删除索引。
+
+## 语法
+```
+DROP INDEX [IF EXISTS] index_name;
+```
+
+## 参数说明
+- `DROP INDEX`：删除索引的关键字。
+- `IF EXISTS`：可选参数，如果指定的索引不存在，则不报错。
+- `index_name`：要删除的索引名称。
+
+## 使用示例
+
+示例1：删除名为 `bf_index` 的索引
+```
+DROP INDEX bf_index;
+```
+
+示例2：删除名为 `bf_index` 的索引，如果不存在则不报错。
+```
+DROP INDEX IF EXISTS bf_index;
+```
+
+## 注意事项
+- 删除索引并不会立即释放索引所占用的存储空间。后续新增的数据将不会为该索引构建索引数据。

+IF EXISTS `connection_name`是用户希望删除的CONNECTION对象的名称。使用`IF EXISTS`选项可以在CONNECTION不存在时避免出现错误，确保删除操作的顺利执行。
+
+## 使用示例
+
+1. 删除特定的CONNECTION对象：
+
+   ```SQL
+   DROP CONNECTION my_connection;
+   ```
+
+   执行这个命令将会删除名为`my_connection`的CONNECTION对象。在执行删除操作之前，建议确认该CONNECTION不再被任何查询或作业使用。
+
+2. 在删除前检查CONNECTION是否存在：
+
+   ```SQL
+   DROP CONNECTION IF EXISTS my_connection;
+   ```
+
+   使用`IF EXISTS`选项可以在尝试删除一个可能不存在的CONNECTION时避免错误发生。这在自动化脚本或批量删除操作中特别有用，可以确保操作的顺利进行，即使某些CONNECTION已经不存在。

+
+填写好必填的配置项后，点击“确认”按钮新建规则。
+
+3. 举例：如果您希望检测某个表的记录数是否符合预期，可以选择“记录数”作为内置指标，设置取值过滤为特定分区，期待结果为一个具体数值，触发方式为定时触发，执行集群为您的工作空间下的计算集群。
+
+### 试跑质量规则
+
+新建质量规则后，建议您使用“试跑”功能来验证配置的正确性。试跑成功后，您可以查看试跑结果，以便对规则进行调整。
+
+![](.topwrite/assets/image_1760004576132.png)
+
+### 查看试跑结果
+
+点击“试跑”后，按照提示点击“查看结果”可以查看试跑校验的结果
+
+![](.topwrite/assets/image_1699875850066.png)
+
+### 配置监控告警
+
+为确保数据质量问题得到及时处理，您可以为质量规则配置监控告警。有两种方式：
+
+1. **开启全局的质量监控告警**：在监控告警模块中搜索“数据质量检测失败”，开启系统内置的全局质量校验监控规则。
+   ![](.topwrite/assets/image_1699875920709.png)
+2. **配置自定义的质量监控告警**：创建自定义监控规则，选择“质量规则校验失败”作为监控消息，并设置过滤条件，如工作空间或具体校验对象。
+   ![](.topwrite/assets/image_1699875932007.png)
+
+## 校验对象
+
+在校验对象页面，您可以按照校验对象（表）的维度管理全部质量规则。使用搜索过滤区域，您可以快速定位到特定的规则。
+
+![](.topwrite/assets/image_1699875683208.png)
+
+## 校验结果
+
+### 校验结果列表
+
+在校验结果列表页面，您可以查看全部质量规则的运行情况。通过搜索和过滤区域，您可以精确地找到所需的校验结果。
+
+![](.topwrite/assets/image_1699875971234.png)
+
+### 校验结果的操作
+
+针对每个校验结果，您可以执行以下操作：
+
+* **终止**：取消当前的校验运行。
+* **置成功/置失败**：将校验结果人为置为成功或失败。
+* **再次校验**：触发质量校验的再次运行。请注意，如果校验失败的规则再次校验通过，不会继续触发监控告警的发送。
+
+通过以上功能，您可以有效地管理和监控数据质量，确保数据在业务中的应用价值得到充分发挥。

+# 存储连接（Storage Connection）
+
+Storage Connection 是云器 Lakehouse 中 Connection 对象的一种类型，属于工作空间（workspace）级别的对象，用于存储从 Lakehouse 访问云对象存储（如阿里云 OSS、腾讯云 COS、亚马逊云 S3）、其他数据平台（如 Hive）以及实时流数据（如 Kafka）中的数据时所需的身份认证和访问控制信息。它是 Lakehouse Volume 对象、External Table、External Catalog 以及 Autoloader 等对象访问外部数据的前提条件。
+
+> 注意：如果未开通对象存储服务，同时需要通过文件方式上传数据至云器 Lakehouse，可以通过上传数据到 [内部Volume](internal_volume.md)。这种方式不需要用户开通云对象存储服务。
+
+### 使用限制：
+
+* 目前不支持跨云的对象存储连接。例如：开通的云器 Lakehouse 实例在阿里云上海站点，则此实例中不支持连接其他非阿里云的对象存储。
+* 一个对象存储的存储连接可以用于创建多个 Volume 对象。

+# 配置和使用云器Lakehouse MCP Server
+
+## 高级配置
+
+### 1. 启用MCP工具集成
+
+如果您的环境支持MCP（Model Context Protocol）工具，可以通过命令行方式添加[MCP服务器](LakehouseMCPServer.md)：
+
+```bash
+# 添加HTTP类型的MCP服务器
+Datus> .mcp add --transport http clickzetta_mcp_http http://localhost:8002/mcp
+
+# 或者添加SSE类型的MCP服务器
+Datus> .mcp add --transport sse clickzetta_mcp_sse http://localhost:8003/sse
+
+# 查看已添加的MCP服务器列表
+Datus> .mcp list
+
+# 检查MCP服务器连接状态
+Datus> .mcp check clickzetta_mcp_http
+
+# 调用MCP工具（格式：服务器名.工具名，具体工具名请通过.mcp check查看）
+Datus> .mcp call clickzetta_mcp_http.工具名称
+
+# 配置工具过滤器（可选）
+Datus> .mcp filter set clickzetta_mcp_http --allowed 工具名1,工具名2 --enabled true
+
+# 查看工具过滤器配置
+Datus> .mcp filter get clickzetta_mcp_http
+
+# 删除MCP服务器（如需要）
+Datus> .mcp remove clickzetta_mcp_http
+```
+
+**MCP 命令说明**：
+
+* `.mcp list` - 查看所有 MCP 服务器
+* `.mcp check <name>` - 检查服务器连接状态并显示可用工具
+* `.mcp call <server.tool>` - 调用特定工具，格式为“服务器名.工具名”
+* `.mcp filter set <server> --allowed 工具名1,工具名2` - 设置允许的工具列表
+* `.mcp filter get <server>` - 查看当前过滤器配置
+* `.mcp remove <name>` - 删除 MCP 服务器
+
+**重要提示**：具体可用的工具名称需要先添加 MCP 服务器，然后通过 `.mcp check <server_name>` 命令查看。
+
+#### 通过subagent使用MCP工具（推荐方式）
+
+添加MCP服务器后，建议通过subagent来使用MCP工具，这样可以在添加过程中选择需要的工具：
+
+```bash
+# 添加subagent（会启动交互式向导）
+Datus> .subagent add
+
+# 查看所有配置的subagent
+Datus> .subagent list
+
+# 为subagent构建知识库（可选）
+Datus> .subagent bootstrap agent_name
+
+# 删除subagent（如需要）
+Datus> .subagent remove agent_name
+```
+
+**subagent 命令说明**：
+
+* `.subagent add` - 启动交互式向导添加新的智能代理，可以在此过程中选择 MCP 工具
+* `.subagent list` - 列出所有已配置的子代理
+* `.subagent bootstrap <agent_name>` - 为指定代理构建专门的知识库
+* `.subagent remove <agent_name>` - 删除指定的子代理
+
+**添加 subagent 时请设置**：
+
+```
+agent_description: ClickZetta Lakehouse assistant with MCP tool integration
+```
+
+```
+rules:
+      - Detect user intent: distinguish between analysis requests and SQL generation
+        requests
+      - For analysis/explanation requests: focus on interpreting results, use markdown
+        format
+      - For SQL generation requests: provide executable statements with explanations
+        in JSON format
+      - Use MCP tools for instance switching, job history, system operations,etc
+      - When users mention "instance switching", "job history", or similar operations
+        - call MCP tools
+      - Prefer specialized analysis tools over basic data collection tools when available
+      - Use single comprehensive tools over multiple basic tool combinations when
+        possible
+      - Choose tools designed for the specific analysis type rather than generic tools
+      - When using MCP analysis tools: focus on explaining the tool results rather
+        than auto-generating SQL
+```
+
+通过 subagent 方式使用 MCP 工具的优势：
+
+* 可以在添加过程中交互式选择需要的工具
+* 为每个场景创建专门的智能代理
+* 支持构建专门的知识库来提升分析能力
+
+**MCP 工具启用后的功能**：
+
+* 实例管理和切换
+* 作业历史查询
+* 高级数据分析工具
+* 系统监控功能

+# Dify中集成Lakehouse MCP Server
+
+Dify 的 Agent 应用中，支持直接集成来自外部 [MCP](https://modelcontextprotocol.io/introduction) 服务器的[工具](https://modelcontextprotocol.io/docs/concepts/tools)。这给Lakehouse与您的Dify AI应用集成提供了新方式。
+Lakehouse MCP Server通过这种方式实现和Dify的集成，来自Lakehouse MCP Server的丰富的工具可以在Dify 的 Agent 轻松调起来。
+
+## Dify MCP 服务器管理界面
+
+登录 Dify 后，在左侧导航栏中依次点击 **工具** → **MCP**，即可进入外部 MCP 服务器的管理页面。在这里，你可以统一管理所有为自身应用配置的 MCP 服务器。
+
+## 添加 Lakehouse MCP 服务器
+
+首先你需要部署支持[HTTP协议的Lakehouse MCP Server](LakehouseMCPServer_intro.md)
+
+:-: ![](.topwrite/assets/image_1756885164463.png =815)
+
+点击 **添加 MCP 服务器（HTTP**），即可集成Lakehouse MCP Server工具服务。需要填写如下信息：
+
+* **服务器 URL**：Lakehouse MCP 服务器的 HTTP 接口地址，例如集成 Notion 时为 `http://192.168.1.220:8001/mcp`。
+* **名称与图标**：自定义服务器名称，建议选择能清晰体现工具用途的名字。Dify 会自动尝试获取服务器域名的图标，你也可以手动上传。比如：clickzetta-mcp-server-mcp-220
+* **服务器标识符**：Dify 用于区分服务器的唯一 ID。规则：小写字母、数字、下划线或连字符，最多 24 个字符。比如clickzetta\_mcp\_mcp\_220
+
+服务器 ID 一旦创建即无法更改。如果更改服务器 ID，所有依赖该服务器工具的 Agent 或 Workflow 都会失效。这一设计对于[应用迁移](https://docs.dify.ai/zh-hans/guides/tools/mcp##application-portability)尤为重要。
+
+添加服务器后，Dify 会自动执行如下操作：
+
+1. **检测可用工具**：自动识别该服务器能提供哪些工具功能。
+2. **处理授权流程**：如服务器需要身份验证，则自动发起 OAuth 授权流程。
+3. **获取工具定义**：下载各工具的接口定义（schema）。
+4. **同步工具列表**：将识别到的工具加入 Agent 或Workflow应用的构建页面。
+
+当 Dify 成功获取到至少一个可用工具后，会在页面中显示该服务器的信息卡片：
+
+:-: ![](.topwrite/assets/image_1756885349165.png =806)
+
+## 管理已连接服务器
+
+点击对应服务器卡片，可进行以下操作：
+
+* **更新工具**：重新从服务器获取最新工具信息，适用于服务方新增或调整功能后更新。
+
+* **重新授权**：点击授权状态，更新服务器的访问权限（如令牌失效需重新授权）。
+
+* **编辑配置**：可修改服务器信息。
+
+更改服务器 URL 会触发重新授权，修改服务器 ID 会让已有应用失效！
+
+:-: ![](.topwrite/assets/image_1756885405845.png =478)
+
+* **移除服务器**：断开服务器连接。此后所有依赖该服务器工具的应用都会报错，直到你重新连接或删除相关工具。
+
+:-: ![](.topwrite/assets/image_1756885449635.png =473)
+
+当服务器配置完成后，其下的工具会出现在应用构建时的工具选择区：
+
+## 设计Agent 应用
+
+:-: ![](.topwrite/assets/image_1756885639345.png =816)
+
+* 在 Agent 配置界面，与内置工具并列显示 MCP 工具。
+* 可一键”添加全部”，快速启用该服务器下的所有工具。
+* 在Agent节点的指令部分，设置为： 你是clickzetta lakehouse资深产品专家，请帮助用户回答和解决问题。对于clickzetta lakehouse相关的问题，如果没有合适的tool，你需要先通过get\_product\_knowledge这个tool查产品知识库获得知识。作为产品专家，你不能编造任何假设性的产品知识和判断。一切要基于MCP tools的调用的知识和客观结果。
+
+## 发布Agent 应用
+
+:-: ![](.topwrite/assets/image_1756885966336.png =786)
+
+## 访问Agent 应用
+
+发布后，点击在'探索'中打开，在浏览器里访问Agent应用，这里可以按照对话内容调度起来Lakehouse MCP Server对应的tools。

+# 基于云器Lakehouse构建面向ELT的Modern Data Stack
+
+随着企业数据量和数据架构的日益复杂，企业急需寻找更快、更高效、更节省成本的数据管理和分析方法。近年来，现代化数据栈（Modern Data Stack，简称 MDS）不断创新发展，受到了广泛的关注。
+
+## MDS是什么？
+
+MDS是一系列基于云的数据工具和技术的总称，它们以云数据仓库、数据湖或Lakehouse为核心，实现了数据的存储、处理、分析和可视化。在过去十年里，以Snowflake、AWS Redshift、GCP BigQuery、MaxCompute为代表的云数据仓库迅速发展壮大，并逐渐演变为集数据仓库和数据湖于一体的Lakehouse架构，它们利用大规模并行处理和SQL支持，使得大数据的处理变得更快、更便宜。在此基础上，涌现了许多低代码、易集成、可扩展且经济的云原生数据工具，如Fivetran、Airbyte、dbt、dagster、Looker等。MDS改变了企业数据管理和分析的方式，让数据变得更加有价值。
+
+云器 Lakehouse 就是在这样的背景下诞生的，它是一个专注于数据的平台，帮助企业管理数据并充分利用数据，为企业构建现代化数据栈 MDS 提供全新的方案。
+
+## 现代数据栈有哪些关键特征？
+
+1. 云优先。MDS基于云，具有更强的可扩展性和弹性，而且可以轻松地与现有的云基础设施集成。
+2. 以云数据仓库/数据湖/Lakehouse为中心。MDS旨在与Redshift、BigQuery、Snowflake、Databricks、MaxCompute、云器Lakehouse等云数据仓库，以及数据湖和Lakehouse无缝集成。
+3. 模块化设计。MDS可以防止供应商锁定，为企业提供更大的灵活性和对数据栈的控制权。
+4. 以SaaS或开源为主。虽然开源是一件好事，但它需要较高的专业水平，因此SaaS的全托管模式更受欢迎。
+5. 降低门槛。借助MDS，企业内的每个人都可以获取和使用他们需要的数据，而不是将数据局限在某些特定的团队或部门。这有助于实现数据的民主化，并培养企业的数据文化。
+
+## 传统数据栈与现代化数据栈的差别
+
+### 传统数据栈：
+
+* 需要高技术水平
+* 依赖大量基础设施
+* 耗费时间
+
+### 现代化数据栈：
+
+* 打破云和数据的束缚
+* 简便易用
+* 工具套件适合非技术人员和业务部门使用
+* 节约时间
+
+## 为什么数据栈很重要？
+
+“时间就是金钱。”这句老话虽然陈旧，但却是事实，尤其对于数据驱动的公司而言。数据栈处理原始数据的效率决定了数据分析和数据科学团队获取数据价值的速度。拥有合适的工具是现代化数据栈的关键，也是公司成功的关键。
+
+## MDS的基本组成部分
+
+要了解 MDS 工具的优势并做出恰当的工具选择，首先需要了解数据平台的各个组件以及为每个组件提供服务的工具的通用功能。
+
+数据平台的基本组件（按照数据流方向）包括：
+
+* 数据摄取（**E**）
+* 数据存储与处理（**L**，数据仓库/数据湖/Lakehouse）
+* 数据转换（**T**）
+* 指标层（Headless BI）
+* 商业智能工具
+* 逆向ETL
+* 编排（工作流引擎）
+* 数据管理、质量和治理
+  ![](.topwrite/assets/image_1718933542634.png)
+
+## 从ETL到ELT
+
+ETL 和 ELT 都描述了将数据集成用于在数据仓库、Lakehouse中进行数据分析、商业智能和数据科学之前清理、丰富和转换来自各种来源的数据的过程。
+
+* **E**xtract（抽取）是指从 SQL 或 NoSQL 数据库、XML 文件或云平台等源提取数据的过程。
+* **T**ransform（转换）是指转换数据集的格式或结构以匹配目标系统的过程。
+* **L**oad（加载）是指将数据集放入目标系统（数据仓库、Lakehouse）的过程。
+
+![](.topwrite/assets/image_1718933554740.png)
+
+### ETL
+
+#### **ETL 代表 Extract > Transform > Load**
+
+在 ETL 过程中，数据转换是在数据仓库外部的暂存区域中执行的，并且在加载之前必须转换整个数据。因此，转换较大的数据集可能需要很长时间，但一旦 ETL 过程完成，就可以立即进行分析。
+
+#### ETL流程
+
+1. 从源中提取预定的数据子集。
+2. 数据在暂存区域中以某种方式进行转换，例如数据映射、应用串联或计算。为了应对传统数据仓库的限制，有必要在加载数据之前对其进行转换。
+3. 数据被加载到目标数据仓库系统中，并准备好由BI 工具或数据分析工具进行分析。
+
+![](.topwrite/assets/image_1718933568004.png)
+
+### ETL
+
+#### **ELT 代表 Extract > Load > Transform**
+
+在 ELT 过程中，数据转换是在目标系统本身中根据需要执行的。因此，转换步骤花费的时间很少，但如果云解决方案中没有足够的处理能力，则可能会减慢查询和分析过程。
+
+#### ELT流程
+
+1. 所有数据均从源中提取。
+2. 所有数据都会立即加载到目标系统（ 数据仓库、 Lakehouse）中。这可以包括原始数据、非结构化、半结构化和结构化数据类型。
+3. 数据在目标系统中进行转换，并准备好由 BI 工具或数据分析工具进行分析
+
+通常，ELT 的目标系统是基于云的数据仓库或 Lakehouse。Amazon Redshift、Snowflake、Databricks 和 云器Lakehouse 等基于云的平台提供近乎无限的存储和强大的处理能力。这允许用户近乎实时地提取和加载他们可能需要的任何和所有数据。云平台可以随时转换任何 BI、分析或预测建模需要的数据。
+
+![](.topwrite/assets/image_1718933580647.png)
+
+### 为什么选择ELT？
+
+* **实时、灵活的数据分析**。 用户可以灵活地从任何方向探索完整的数据集，包括实时数据，而无需等待 数据工程师提取、转换和加载更多数据。
+* **更低的成本和更少的维护**。 ELT 受益于基于云的平台的强大生态系统，该生态系统提供更低的成本和各种存储和处理数据的计划选项。而且，鉴于所有数据始终可用且转换过程通常是自动化且基于云的，ELT 过程通常需要很少的维护。
+
+## 基于云器Lakehouse构建面向ELT的Modern Data Stack
+
+### ELT在MDS中的位置
+
+![](.topwrite/assets/image_1718933593607.png)
+
+#### 数据摄取-Airbyte
+
+Airbyte是领先的数据集成平台，适用于从 API、数据库和文件到数据仓库、数据湖和Lakehouse的 ETL/ELT 数据管道。
+
+Airbyte 已经为 API、数据库、数据仓库和Lakehouse提供了包含 300 多个连接器，同时开发新的连接器也非常方便，以支持多源著称，**特别适合长尾数据源的场景**。
+
+#### 数据存储与处理-云器Lakehouse
+
+云器 Lakehouse是一种湖仓架构的全托管数据管理及分析服务。云器 Lakehouse以单一引擎满足数仓构建、数据湖探查分析、离线和实时数据处理与分析、业务报表等场景需求，通过存算分离、Serverless弹性算力、智能优化特性满足企业不同阶段对扩展性、成本和性能需要。内置数据集成、开发与运维、数据资产管理等开通即用服务，极大简化数据开发与管理工作、加速企业数据洞察及价值实现。
+
+#### 数据转换-dbt
+
+dbt 使数据分析师和工程师能够使用与软件工程师构建应用程序相同的实践来转换数据。使用 dbt 的分析师只需编写 select 语句即可转换数据，而 dbt 则负责将这些语句转换为数据仓库中的表和视图。
+
+这些select语句或“模型”形成一个 dbt 项目。模型经常相互构建 - dbt 可以轻松*管理模型之间的关系*、*可视化这些关系*，并通过*测试*确保转换的质量。
+
+dbt 通过管理事务、删除表和管理架构更改来避免编写样板 *DML* 和 *DDL*。只需使用 SQL select 语句或返回所需数据集的 Python DataFrame 编写**业务逻辑**，然后 dbt 负责物化。
+
+dbt 生成有价值的元数据来查找长时间运行的查询，并具有对标准转换模型（例如完整或增量加载）的内置支持。
+
+#### 数据工作流-dagster
+
+Dagster 是一个编排器，旨在开发和维护数据资产，例如表、数据集、机器学习模型和报告。
+
+您可以声明要运行的函数以及这些函数生成或更新的数据资产。然后，Dagster 可以帮助您在正确的时间运行您的功能并使您的资产保持最新状态。
+
+Dagster 旨在用于数据开发生命周期的每个阶段 - 本地开发、单元测试、集成测试、暂存环境，一直到生产。
+
+与 dbt 一样，它强制执行最佳实践，例如编写声明性、抽象、幂等和类型检查函数以尽早捕获错误。Dagster 还包括简单的单元测试和方便的功能，使管道可靠、可测试和可维护。它还与 Airbyte 深度集成，允许将*数据集成为代码*。

+
+#### 数据转换（dbt）
+
+##### 配置DBT的profile.yml
+
+这里的target:指向clickzetta\_uat，也就是说该项目里的数据转换都是运行在clickzetta\_uat上。目标表将会输出到云器Lakehouse的名为ql\_ws的workspace下的modern\_data\_stack schema里。计算资源会使用名为default的vcluster。
+
+```SQL
+mds_dbt:
+  target: clickzetta_uat
+  outputs:
+    mds_source:
+      type: postgres
+      host: 172.17.1.220
+      port: 5432
+      user: metabase
+      pass: metasample123
+      dbname: mds_source

+      password: metasample123
+      driver: MySQL ODBC 8.0 ANSI Driver
+      threads: 2
+      keepalives_idle: 0
+```
+
+##### 定义DBT的source.yml
+
+```SQL
+version: 2
+
+sources:
+  - name: ql_ws
+    database: ql_ws
+    schema: modern_data_stack
+    tables:
+      - name: orders
+        identifier: _airbyte_raw_orders
+        description: "订单表，包含所有订单数据。"
+      - name: users
+        identifier: _airbyte_raw_users
+        description: "用户表，包含用户信息。"
+      - name: departments
+        identifier: departments
+        description: "员工信息，departments table"
+      - name: dept_emp
+        identifier: dept_emp
+        description: "员工信息，dept_emp table"
+      - name: dept_manager
+        identifier: dept_manager
+        description: "员工信息，dept_manager table"
+      - name: employees
+        identifier: employees
+        description: "员工信息，employees table"
+      - name: salaries
+        identifier: salaries
+        description: "员工信息，salaries table"
+      - name: titles
+        identifier: titles
+        description: "员工信息，titles table"
+```
+
+##### 开发DBT的转换模型
+
+DBT 会根据 SELECT 语句生成和文件名一样的目标表或者视图，这个由 `dbt_project.yml` 里的配置确认。比如：
+
+models:
+
+mds\_dbt:
+
++materialized: "table"
+
+表示数据转换目标类型为table，而不是view。如果需要生成的是view，需要设置成：
+
+models:
+
+mds\_dbt:
+
++materialized: "view"
+
+以下是数据转换模型：
+
+user\_augmented.sql
+
+```SQL
+select
+        cast(from_json(_airbyte_data,'struct<index:bigint,user_id:bigint,is_bot:boolean>').index as int) as index,
+        cast(from_json(_airbyte_data,'struct<index:bigint,user_id:bigint,is_bot:boolean>').user_id as string) as user_id,
+        cast(from_json(_airbyte_data,'struct<index:bigint,user_id:bigint,is_bot:boolean>').is_bot as boolean) as is_bot
+from {{ source('ql_ws', 'users') }}
+```
+
+orders\_cleaned.sql
+
+```SQL
+select
+        cast(from_json(_airbyte_data,'struct<index:bigint,user_id:bigint,order_time:string,order_value:double>').index as int) as index,
+        cast(from_json(_airbyte_data,'struct<index:bigint,user_id:bigint,order_time:string,order_value:double>').user_id as string) as user_id,
+        cast(from_json(_airbyte_data,'struct<index:bigint,user_id:bigint,order_time:string,order_value:double>').order_time as timestamp) as order_time,
+        cast(from_json(_airbyte_data,'struct<index:bigint,user_id:bigint,order_time:string,order_value:double>').order_value as double) as order_value,
+from {{ source('ql_ws', 'orders') }}
+```
+
+daily\_order\_summary.sql
+
+```SQL
+select

+# EXTERNAL FUNCTION 开发指南
+
+## 概述
+
+EXTERNAL FUNCTION 是一种在数据库中直接执行外部程序或脚本的机制。通过使用外部函数，您可以将数据库与外部程序或脚本进行交互，从而实现更丰富的功能。
+
+## 支持的编程语言
+
+目前支持的编程语言包括 Java 和 Python。
+
+## Java 语言
+
+### 1. 编写 Java 类
+
+首先，您需要编写一个 Java 类，并实现一个静态方法作为外部函数的入口点。例如，创建一个名为 `MyJavaClass` 的 Java 类，并实现一个静态方法 `hello`：
+
+```java
+public class MyJavaClass {
+    public static String hello(String name) {
+        return "Hello, " + name + "!";
+    }
+}
+```
+
+### 2. 将 Java 类编译为 JAR 文件
+
+将编写好的 Java 类编译为 JAR 文件。例如，将 `MyJavaClass` 编译为 `myjavaclass.jar`。
+
+### 3. 在数据库中注册 Java 类
+
+在数据库中注册 Java 类，以便可以在外部函数中使用。例如，在 MySQL 数据库中，可以使用以下命令注册：
+
+```sql
+CREATE FUNCTION my_hello FUNCTION
+  -> 'MyJavaClass.hello'
+  -> RETURNS STRING
+  -> LANGUAGE JAVA
+  -> DATABINARY AS '/path/to/myjavaclass.jar';
+```
+
+### 4. 使用外部函数
+
+在数据库中调用外部函数，例如：
+
+```sql
+SELECT my_hello('World');
+```
+
+## Python 语言
+
+### 1. 编写 Python 脚本
+
+首先，您需要编写一个 Python 脚本，并实现一个函数作为外部函数的入口点。例如，创建一个名为 `my_python_script.py` 的 Python 脚本，并实现一个函数 `hello`：
+
+```python
+def hello(name):
+    return "Hello, " + name + "!"
+```
+
+### 2. 将 Python 脚本保存到数据库
+
+将编写好的 Python 脚本保存到数据库中。例如，在 MySQL 数据库中，可以使用以下命令保存：
+
+```sql
+CREATE FUNCTION my_hello FUNCTION
+  -> 'hello'
+  -> RETURNS STRING
+  -> LANGUAGE PYTHON
+  -> DATABINARY AS '/path/to/my_python_script.py';
+```
+
+### 3. 使用外部函数
+
+在数据库中调用外部函数，例如：
+
+```sql
+SELECT my_hello('World');
+```
+
+## 使用示例
+
+### 示例 1：计算圆的面积
+
+使用 Python 脚本计算圆的面积，并在数据库中调用该外部函数。
+
+1. 编写 Python 脚本 `calculate_circle_area.py`：
+
+```python
+def calculate_circle_area(radius):
+    return 3.14159 * radius * radius
+```
+
+2. 将 Python 脚本保存到数据库：
+
+```sql
+CREATE FUNCTION calculate_circle_area FUNCTION
+  -> 'calculate_circle_area'
+  -> RETURNS DECIMAL(10, 2)
+  -> LANGUAGE PYTHON
+  -> DATABINARY AS '/path/to/calculate_circle_area.py';
+```
+
+3. 在数据库中调用外部函数：
+
+```sql
+SELECT calculate_circle_area(5);
+```
+
+### 示例 2：查询股票价格
+
+使用 Java 类查询股票价格，并在数据库中调用该外部函数。
+
+1. 编写 Java 类 `StockPriceFetcher`：
+
+```java
+public class StockPriceFetcher {
+    public static String getStockPrice(String stockCode) {
+        // 查询股票价格的逻辑
+        return "100.0";
+    }
+}
+```
+
+2. 将 Java 类编译为 JAR 文件。
+
+3. 在数据库中注册 Java 类：
+
+```sql
+CREATE FUNCTION get_stock_price FUNCTION
+  -> 'StockPriceFetcher.getStockPrice'
+  -> RETURNS STRING
+  -> LANGUAGE JAVA
+  -> DATABINARY AS '/path/to/stock_price_fetcher.jar';
+```
+
+4. 在数据库中调用外部函数：
+
+```sql
+SELECT get_stock_price('AAPL');
+```
+
+通过上述示例，您可以更好地理解如何使用 EXTERNAL FUNCTION 将数据库与外部程序或脚本进行交互。请根据您的实际需求进行相应的调整和优化。

+# EXTERNAL SCHEMA
+>**【预览发布】本功能当前处于公开预览发布阶段。**
+## 简介
+
+外部 Schema（EXTERNAL SCHEMA）是 Lakehouse 提供的一项查询外部数据源的功能，借助 EXTERNAL SCHEMA 可以实现与外部元数据服务（如 HMS）的访问以及外表的批量映射，无需将数据导入 Lakehouse。例如，通过与Hive的Database建立映射，并利用Hive元数据服务（HMS）接口，外部Schema能够直接获取Hive的元数据信息，但不会在Lakehouse中实际创建表结构。
+使用 EXTERNAL SCHEMA 可以带来如下收益：
+1. **直接查询**：通过 EXTERNAL SCHEMA，用户可以直接对外部数据库（如 Apache Hive）中的数据进行查询，而无需进行复杂的数据导入过程。由于 Lakehouse 性能更优，也可以起到为第三方引擎加速查询的作用。
+2. **数据转换和导入**：结合使用`INSERT INTO ..SELECT`语句，用户可以实现数据的提取、转换和加载（ETL），将查询结果直接写入到Lakehouse的表中。
+3. **实时联接**：EXTERNAL SCHEMA支持将Lakehouse的表与外部数据源中的数据进行实时联接，这意味着用户可以在数据发生变化时直接查询，而不是等待数据重新加载。
+4. **删除行为说明**：删除外部 Schema 不会删除 Hive 中的 Database，因为外部 Schema 仅是与 Hive 中的 Database 建立了映射关系，删除操作只会移除 Lakehouse 中的外部 Schema 元数据信息。
+
+这种设计提供了极大的灵活性和便利性，因为它减少了数据迁移的需要，并使得用户能够实时地查询和分析存储在外部数据源中的数据。
+## 外部Catalog和外部Schema使用关系
+外部 Catalog 和外部 Schema 形成两层映射结构。外部 Catalog 是顶层容器，直接映射外部数据系统；外部 Schema 是中间层容器，提供细粒度的数据组织。通过将外部Schema关联到内部Catalog，您可以在同一工作空间中统一查询外部和内部表，只需使用 `schema.table` 的简单格式即可。
+## 支持的范围
+
+* Hive on OSS（阿里云对象存储服务）
+* Hive on COS（腾讯云对象存储服务）
+* Hive on GCS（Google云对象存储服务）
+* Hive on HDFS (Preview，请联系 Lakehouse 支持)
+* Databricks
+* 同时支持写入和读取。写入格式支持 Parquet、ORC、Text 文件格式。
+
+## 外部Schema与外部表的区别
+
+* **External Schema**：直接与 Hive 元数据服务（HMS）交互，通过 HMS 接口直接获取 Hive 的元数据信息。
+* **外部表：** 用户可以自定义创建表，指定列内容和表名。
+* **External Schema 限制**：由于是直接映射 HMS，无法在 External Schema 下直接创建、删除表或重命名表。
+* **外部表优势：** 支持重命名和修改注释等操作，因为它们是在内部 Schema 下创建的。
+
+## 外部Schema计费
+
+* **存储费用：** 外部表不产生存储费用，因为数据不存储在Lakehouse中。
+* **计算费用：** 使用外部表进行计算会消耗计算资源，因此会产生计算费用。
+
+## 外部Schema权限
+
+* **创建外部Schema权限：** 需要具有创建Schema（create schema）的权限。
+* **删除外部Schema权限：** 需要具有删除（drop）权限。
+* **外部 Schema 下表的权限**：目前单独表无法单独授权，只支持 ALL TABLES 权限。
+
+
+## 管理
+
+云器 Lakehouse 提供了创建和删除 EXTERNAL SCHEMA 的命令，以便用户可以根据需要管理这些外部数据源的访问权限和配置。
+
+- **创建EXTERNAL SCHEMA**：用户可以通过`CREATE EXTERNAL SCHEMA`命令来创建一个新的EXTERNAL SCHEMA，从而开始与外部数据库进行交互。具体的语法和参数设置可以在[创建EXTERNAL SCHEMA](CREATEEXTERNAlLSCHEMA.md)文档中找到。
+- **删除EXTERNAL SCHEMA**：如果某个EXTERNAL SCHEMA不再需要，或者用户希望移除对外部数据库的访问权限，可以使用`DROP SCHEMA`命令来删除它。相关的操作步骤和注意事项在[删除EXTERNAL SCHEMA](DROPSCHEMA.md)文档中有详细说明。
+
+## 权限说明
+
+* **创建外部Schema权限：** 需要具有创建Schema（create schema）的权限。
+* **删除外部Schema权限：** 需要具有删除（drop）权限。
+* **外部 Schema 下表的权限**：目前单独表无法单独授权，只支持 ALL TABLES 权限。
+
+
+## 约束限制
+**支持的数据源**：目前，EXTERNAL SCHEMA 主要支持访问 Hive Metastore 元数据服务，且数据需要存储在 HDFS 或阿里云、腾讯云、谷歌云对象存储服务中。
+**操作限制**：在外部 Schema 下，不支持执行创建表、删除表等操作，因为它们是直接映射的。此外，外部 Schema 下的表仅支持只读操作，不允许进行插入、更新、截断或删除等数据操作语言（DML）操作。用户可以执行查询和连接操作，并能基于这些表创建视图。
+**删除行为说明：** 删除外部Schema不会删除源系统中的映射对象（如Hive Database及其包含的表）。
+
+## 使用样例
+
+#### **1. 连接阿里云 OSS**
+
+要连接阿里云 OSS，您需要以下参数，具体参考 *[阿里云OSS文档](https://help.aliyun.com/zh/oss/developer-reference/configure-ossutil)*：
+
+首先，您需要创建一个存储连接，以连接到外部对象存储服务。
+
+```SQL
+CREATE STORAGE CONNECTION if not exists catalog_storage_oss
+    type OSS
+    ACCESS_ID='LTAIxxxxxxxxxxxx'
+    ACCESS_KEY='T8Gexxxxxxmtxxxxxx'
+    ENDPOINT='xxx';
+```
+接着，创建一个目录连接，指向 Hive 元数据存储服务（Hive Metastore）。
+
+```SQL
+CREATE CATALOG CONNECTION if not exists connection_name
+    type hms
+    hive_metastore_uris='metastore_uris'
+    storage_connection='storage_connection';
+```
+
+```SQL
+CREATE EXTERNAL SCHEMA if not exists schema_name
+    CONNECTION connection_name
+    options(SCHEMA='hive_database_name');
+```

+# External Function 开发指南（Java）
+
+本篇文档将介绍如何使用Java语言开发UDF、UDAF、UDTF类型的外部函数。
+注：External Function 当前处于预览阶段，需要使用文档中说明的控制参数进行启用。
+
+# UDF
+
+云器 Lakehouse UDF 支持基于 Hive UDF API 规范开发函数，支持使用 GenericUDF (org.apache.hadoop.hive.ql.udf.generic.GenericUDF) 和 UDF (org.apache.hadoop.hive.ql.exec.UDF) 开发标量函数。
+
+## 开发UDF
+
+创建MAVEN项目，在pom.xml添加依赖。
+
+```XML
+<dependency>
+    <groupId>org.apache.hive</groupId>
+    <artifactId>hive-exec</artifactId>
+    <version>2.3.8</version>
+    <scope>provided</scope>
+    <exclusions>
+        <exclusion>
+            <groupId>org.pentaho</groupId>
+            <artifactId>*</artifactId>
+        </exclusion>
+    </exclusions>
+</dependency>
+```
+
+编写UDF代码，示例如下：
+
+```Java
+package com.example;
+
+import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
+import org.apache.hadoop.hive.ql.metadata.HiveException;
+import org.apache.hadoop.hive.ql.udf.generic.GenericUDF;
+import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspector;
+import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector;
+import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector.PrimitiveCategory;
+import org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory;
+import org.apache.hadoop.hive.serde2.objectinspector.primitive.StringObjectInspector;
+
+import java.util.Locale;
+
+public class GenericUdfUpper extends GenericUDF {
+
+  private StringObjectInspector soi;
+
+  @Override
+  public ObjectInspector initialize(ObjectInspector[] arguments) throws UDFArgumentException {
+    checkArgsSize(arguments, 1, 1);
+    checkArgPrimitive(arguments, 0);
+    if (((PrimitiveObjectInspector) arguments[0]).getPrimitiveCategory() != PrimitiveCategory.STRING) {
+      throw new UDFArgumentException("argument 0 requires to be string rather than " + arguments[0].getTypeName());
+    }
+    soi = (StringObjectInspector) arguments[0];
+    return PrimitiveObjectInspectorFactory.javaStringObjectInspector;
+  }
+
+  @Override
+  public Object evaluate(DeferredObject[] arguments) throws HiveException {
+    Object arg = arguments[0].get();
+    if (arg == null) {
+      return null;
+    }
+    return soi.getPrimitiveJavaObject(arg).toUpperCase(Locale.ROOT);
+  }
+
+  @Override
+  public String getDisplayString(String[] children) {
+    return "upper";
+  }
+}
+```
+
+打包项目为 JAR 文件。
+
+## 上传JAR文件到Volume中
+
+将打包好的 JAR 文件上传至云器 Lakehouse 中创建的 External Volume 中。
+
+首先，创建CONNECTION对象用于连接您已有的对象存储地址。
+
+```SQL
+--创建指向对象存储的服务连接定义
+CREATE OR REPLACE STORAGE CONNECTION  qn_hz_bucket_ramrole
+    TYPE oss
+    REGION = 'cn-hangzhou'
+    ROLE_ARN = 'acs:ram::1875653xxxxx:role/czudfrole'
+    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com';
+```
+
+其次，创建EXTERNAL VOLUME对象MOUNT对象存储的指定路径。
+
+```SQL
+--创建External Volume
+CREATE EXTERNAL VOLUME qn_hz_bucket_vol
+    location 'oss://qn-hz-bucket/'
+    using connection qn_hz_bucket_ramrole
+    directory = (
+        enable=true,
+        auto_refresh=false
+    )
+recursive=true;
+```
+
+最后使用本地 JDBC 客户端，连接工作空间并在本地客户端中使用 PUT 命令上传 JAR 文件（注：Studio Web-UI 的 SQL 编辑器中不支持使用 PUT 命令上传本地文件）。
+
+```SQL
+--上传打包后的UDF JAR
+PUT '/Users/Downloads/upper.jar' TO  VOLUME qn_hz_bucket_vol FILE 'upper.jar';
+
+--查看上传的文件
+SHOW VOLUME DIRECTORY qn_hz_bucket_vol;
+
+relative_path                                   url                                                                size last_modified_time  
+----------------------------------------------- ------------------------------------------------------------------ ---- ------------------- 
+data_parquet/data.csv                           oss://qn-hz-bucket/data_parquet/data.csv                           34   2024-05-29 17:03:25 
+data_parquet/lakehouse_region_part00001.parquet oss://qn-hz-bucket/data_parquet/lakehouse_region_part00001.parquet 2472 2024-05-24 00:39:08 
+upper.jar                                       oss://qn-hz-bucket/upper.jar                                       3161 2024-05-29 23:11:49 
+```
+
+您也可以指定内部volume。虽然您可以使用内部 Volume，但是您在创建 API CONNECTION 中的 code bucket 参数必须填写外部地址。
+
+* **User Volume 格式地址**:`volume:user://~/upper.jar`
+  * `user` 表示使用 User Volume 协议。
+
+  * `~` 表示当前用户，为固定值。
+
+  * `upper.jar` 表示目标文件名。
+* **Table Volume 格式地址**`volume:table://table_name/upper.jar`
+  * `table` 表示使用 Table Volume 协议。
+  * `table_name` 表示表名，需根据实际情况填写。
+  * `upper.jar` 表示目标文件名。
+
+## 创建External Function
+
+首先，创建函数计算服务Connection对象。
+
+```SQL
+create api connection qn_hz_fc_connection
+type cloud_function 
+with properties ( 
+    'cloud_function.provider' = 'aliyun', 
+    'cloud_function.region' = 'cn-hangzhou', 
+    'cloud_function.role_arn' = 'acs:ram::1875653611111111:role/czudfrole', 
+    'cloud_function.namespace' = 'default', 
+    'cloud_function.code_bucket' = 'qn-hz-bucket'
+);
+```
+
+其次，创建External Function，使用前面定义的Volume对象以读取JAR文件，使用已经定义的函数计算连接的CONNECTION对象用于调用函数计算服务创建一一对应的函数。
+
+```SQL
+create external function public.upper_udf 
+as 'com.example.GenericUdfUpper' 
+USING FILE 'volume://qn_hz_bucket_vol/upper.jar'
+connection qn_hz_fc_connection
+with properties ( 
+         'remote.udf.api' = 'java8.hive2.v0',
+          'remote.udf.protocol' = 'http.arrow.v0' 
+);
+```
+
+## 测试运行
+
+借助测试数据或表数据测试运行UDF。
+
+```SQL
+--测试运行UDF
+select public.upper_udf('hello') as upper;
+select public.upper_udf(product_id) from product_grossing limit 50;
+```
+
+具备阿里云控制台访问权限的用户，此时可以登录到阿里云函数计算控制台查看到CREATE EXTERNAL FUNCTION命令执行成功后，云器Lakehouse将自动创建函数以执行自定义函数。
+
+执行 DROP FUNCTION public.upper_udf; 命令删除函数的同时，Lakehouse 平台将同步删除云服务商的对应函数。
+
+# UDAF
+
+支持基于 Hive 2.x UDAF 规范开发函数, 可使用 [GenericUDAFResolver](https://github.com/apache/hive/blob/branch-2.3/ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDAFResolver.java) 和 [GenericUDAFEvaluator](https://github.com/apache/hive/blob/branch-2.3/ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDAFEvaluator.java) 开发 UDAF;
+
+UDAF 函数运行环境：
+
+Java: 1.8 版本 (JDK 发行版由云厂商的函数计算服务运行环境提供)。
+
+创建MAVEN项目，在pom.xml添加依赖。
+
+```XML
+<dependency>
+    <groupId>org.apache.hive</groupId>
+    <artifactId>hive-exec</artifactId>
+    <version>2.3.8</version>
+    <scope>provided</scope>
+    <exclusions>
+        <exclusion>
+            <groupId>org.pentaho</groupId>
+            <artifactId>*</artifactId>
+        </exclusion>
+    </exclusions>
+</dependency>
+```
+
+## UDAF 开发
+
+基于 GenericUDAFResolver 和 GenericUDAFEvalutor 编写 UDAF代码。
+
+```SQL

+```
+
+## 上传JAR文件到Volume中
+
+编译打包为 JAR，上传到用户指定的对象存储位置或 Lakehouse Volume 对象中。
+
+```SQL
+--上传打包后的UDF JAR
+PUT '/Users/Downloads/sumint.jar' TO  VOLUME qn_hz_bucket_vol FILE 'sumint.jar';
+
+--查看上传的文件
+SHOW VOLUME DIRECTORY qn_hz_bucket_vol;
+
+relative_path url                           size last_modified_time  
+------------- ----------------------------- ---- ------------------- 
+upper.jar     oss://qn-hz-bucket/upper.jar  3161 2024-05-29 23:11:49 
+sumint.jar    oss://qn-hz-bucket/sumint.jar 1022 2024-05-30 01:10:28 
+```
+
+## 创建External Function
+
+1.  创建与函数计算服务连接的 Connection 对象（参见 UDF 中的介绍）
+2. 在 LakeHouse 系统中创建外部函数
+
+UDAF的 External Function创建语法说明：
+
+```SQL
+CREATE EXTERNAL FUNCTION public.<funcName>
+    AS '<className>'
+    USING FILE 'oss://<bucket>/<pathToJar>'
+    CONNECTION <connectionName>
+    WITH PROPERTIES (
+        'remote.udf.api' = 'java8.hive2.v0', 
+        'remote.udf.category' = 'AGGREGATOR');
+```
+
+参数说明:
+
+1. functionName: 可使用任意合法标识符, 比如 my\_agg
+2. className: 填写第 1 步中开发的 GenericUDAFResolver 的完整类名, 比如 com.example.GenericUDAFSum;
+3. bucket 和 pathToJar: 填写第 2 步上传到 OSS 的存储桶和对象路径;
+4. connectionName: 使用第 3 步创建的 connection 的名字, 比如 udf\_deploy\_0317;
+5. 最后两个 PROPERTIES 保持原样即可;
+
+示例如下：
+
+```SQL
+--创建External Function
+create external function public.sumint
+as 'com.example.sumint' 
+USING FILE 'volume://qn_hz_bucket_vol/sumint.jar'
+connection qn_hz_fc_connection
+with properties ( 
+         'remote.udf.api' = 'java8.hive2.v0',
+         'remote.udf.category' = 'AGGREGATOR'
+);
+```
+
+## 测试运行
+
+借助测试数据或表数据测试运行 UDF。注：当前需要通过 cz.sql.remote.udf.enabled 参数开启远程函数访问。
+
+```SQL
+--测试运行UDF
+set cz.sql.remote.udf.enabled = true;
+select public.sumint(amount) from product_grossing;
+```
+
+# UDTF
+
+## UDTF 开发
+
+支持继承org.apache.hadoop.hive.ql.udf.generic.GenericUDTF进行UDTF开发。UDTF需要实现initialize, process, close三个方法。UDTF首先会调用initialize方法，此方法返回UDTF的返回行的信息（返回个数，类型）。初始化完成后，会调用process方法，对传入的参数进行处理，可以通过forword()方法把结果返回。最后close()方法调用，对需要清理的方法进行清理。
+
+编写UDTF代码，示例如下：
+
+```Java
+package com.example;
+
+import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
+import org.apache.hadoop.hive.ql.metadata.HiveException;
+import org.apache.hadoop.hive.ql.udf.generic.GenericUDTF;
+import org.apache.hadoop.hive.serde2.objectinspector.*;
+import org.slf4j.Logger;
+import org.slf4j.LoggerFactory;
+
+import java.util.*;
+
+public class MyExplode extends GenericUDTF {
+
+    private static Logger logger = LoggerFactory.getLogger(MyExplode.class);
+    private ObjectInspector oi;
+    private Object[] params;
+
+    @Override
+    public StructObjectInspector initialize(ObjectInspector[] argOIs) throws UDFArgumentException {
+
+        oi = argOIs[0];
+        final ObjectInspector.Category category = oi.getCategory();
+
+        List<String> names = new ArrayList<>(2);
+        List<ObjectInspector> types = new ArrayList<>(2);
+        switch (category){
+
+            case MAP:
+                logger.info("receive explode category : Map");
+                names.add("key");
+                names.add("value");
+                final MapObjectInspector moi = (MapObjectInspector) this.oi;

+                names.add("value");
+                final ListObjectInspector loi = (ListObjectInspector) oi;
+                types.add(loi.getListElementObjectInspector());
+                params = new Object[1];
+                break;
+            default:
+                throw new UDFArgumentException("not supported category for function explode : " + category);
+        }
+        return ObjectInspectorFactory.getStandardStructObjectInspector(names,types);
+    }
+
+    @Override
+    public void process(Object[] args) throws HiveException {
+
+        if (args.length != 1 || Objects.isNull(args[0])){
+
+
+            throw new HiveException("Only 1 nonnull arg supported for function explode, but got " + args.length);
+        }
+        ObjectInspector.Category category = oi.getCategory();
+        switch(category){
+
+            case MAP:
+                final Map<?, ?> map = ((MapObjectInspector) oi).getMap(args[0]);
+                final Iterator<? extends Map.Entry<?, ?>> it = map.entrySet().iterator();
+                while(it.hasNext()){
+
+                    final Map.Entry<?, ?> entry = it.next();
+                    params[0] = entry.getKey();
+                    params[1] = entry.getValue();
+                    forward(params);
+                }
+                break;
+            case LIST:
+                final List<?> list = ((ListObjectInspector) oi).getList(args[0]);
+                final Iterator<?> itl = list.iterator();
+                while (itl.hasNext()) {
+
+
+                    params[0] = itl.next();
+                    forward(params);
+                }
+                break;
+        }
+    }
+
+    @Override
+    public void close() throws HiveException {
+
+        oi = null;
+        for (int i = 0; i < params.length; i++) {
+            params[i] = null;
+        }
+        params = null;
+    }
+}
+```
+
+## 上传JAR文件到Volume中
+
+编译打包为 JAR，上传到用户指定的对象存储位置或 Lakehouse Volume 对象中。

+# FLOAT
+32位二进制浮点型（FLOAT）是一种用于存储实数的数值数据类型，其精度和范围有限。在数据库中，FLOAT类型通常用于存储带有小数部分的数值。
+
+## 语法
+```
+FLOAT
+```
+
+## 示例
+```
+-- 使用 FLOAT 类型存储正数
+SELECT 1.5F;
+
+-- 使用 FLOAT 类型存储负数
+SELECT -3.2F;
+
+-- 将其他数值类型转换为 FLOAT 类型
+SELECT CAST(6.1 AS FLOAT);
+
+-- 在 SELECT 语句中使用 FLOAT 类型
+SELECT FLOAT(salary) FROM employees;
+
+-- 在 WHERE 子句中使用 FLOAT 类型进行条件筛选
+SELECT * FROM products WHERE price < 50.0F;
+```
+
+## 注意事项
+1. FLOAT 类型的数值可能会有精度损失，因此在需要高精度计算的场景下，建议使用 DECIMAL 或 NUMERIC 类型。
+2. 在比较 FLOAT 类型的数值时，应注意其精度和舍入误差，避免因精度问题导致的比较错误。
+3. 在使用 FLOAT 类型时，建议明确指定数值的精度和小数位数，以避免因隐式类型转换导致的意外结果。
+
+## 总结
+32位二进制浮点型（FLOAT）是一种用于存储实数的数值数据类型，适用于存储带有小数部分的数值。在使用时，应注意精度损失、舍入误差和类型转换等问题，确保数据的准确性和可靠性。

+# 使用 Zettapark 扩展客户特征的特征工程
+
+## 概述
+
+本教程展示了如何使用[Zettapark](ZettaparkQuickStart.md)对[TPCH 表](sample-data-using.md)进行特征工程代码的编写。通过本教程，我们将展示如何构建派生（聚合和转换）特征，以支持多个机器学习任务。例如，您可以构建以下内容：
+
+**客户细分/流失预测**：
+
+* 特征数据：每位客户的总消费金额、订单数量、平均订单金额、客户人口统计信息（例如市场细分、账户余额）以及地理信息（国家/地区）。
+* 方法：对订单进行聚合，并通过与客户、国家和地区表连接进行丰富。
+
+**销售预测**：
+
+* 特征数据：基于时间的度量，如总销售额、平均销售额、订单频率以及每位客户或每个地区的趋势。
+* 方法：对订单和行项目细节进行聚合。
+
+**供应商绩效/产品销售分析**：
+
+* 特征数据：对于供应商，包括总可用数量、总供应成本和平均供应成本；对于产品，包括销售金额和频率，可能需要使用`CASE WHEN`对产品类型进行分类转换。
+* 方法：对 partsupp、lineitem 和 part 表进行分组和聚合，并使用`CASE WHEN`转换进行领域特定的分类。
+
+您可以从[GitHub 存储库获取源代码（Jupyter Notebook ipynb 文件）](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/Zettapark/FeatureEngineeringForExpandingCustomerFeatureswithZettapark.ipynb)。

+### 1. 客户销售聚合
+
+* **功能**：
+  此代码按客户键对订单表进行分组，并聚合关键指标，例如每位客户的总销售额（订单总额之和）、订单数量和平均订单价值。这些聚合指标随后被重命名，并与客户表连接，将客户的个人信息（姓名、地址、账户余额等）与其购买行为集成。
+
+* **目标**：
+  构建客户级销售指标数据集，可用于进一步分析或预测建模任务，如客户细分或流失预测。
+
+```python
+# -----------------------------------------
+# 1. 客户销售聚合（源自订单）
+# -----------------------------------------

+        F_avg("O_TOTALPRICE").alias("avg_order_value")
+    ) \
+    .withColumnRenamed("O_CUSTKEY", "customer_sk")
+
+
+# 将聚合后的销售数据与客户详情连接

+
+### 2. 地理特征提取
+
+* **功能**：
+  此代码通过将包含国家键的客户特征与国家表连接，再与地区表连接，为客户数据丰富地理信息。此过程提取每个客户的国家名称和地区名称等属性。
+
+* **目标**：
+  为客户数据集添加地理维度，支持区域绩效分析，并为可能使用地理数据的模型（例如市场细分或基于位置的趋势分析）提供支持。
+
+```python
+# -----------------------------------------
+# 2. 地理特征（使用国家和地区）
+# -----------------------------------------
+customer_geo = customer_features.join(
+    nation,
+    customer_features["C_NATIONKEY"] == nation["N_NATIONKEY"],
+    "left"
+).join(
+    region,
+    nation["N_REGIONKEY"] == region["R_REGIONKEY"],
+    "left"
+).select(
+    customer_features["customer_sk"],
+    nation["N_NAME"].alias("nation_name"),
+    region["R_NAME"].alias("region_name"),
+    customer_features["C_ACCTBAL"]
+)
+
+# 可选：聚合区域级指标
+region_agg = customer_geo.groupBy("region_name") \
+    .agg(
+        F_count("customer_sk").alias("num_customers"),
+        F_avg("C_ACCTBAL").alias("avg_acctbal")
+    )
+```
+
+### 3. 产品销售特征
+
+* **功能**：
+  此代码通过按产品键对行项目表中的记录进行分组，聚合销售数据。它计算每个产品的总扩展价格、平均扩展价格和订单数量。然后，它将这些结果与产品表连接，并使用`when`函数应用条件逻辑（CASE WHEN），将产品类型转换为数值代码。
+
+* **目标**：
+  生成封装关键销售指标的产品级特征，并对产品类型进行数值编码。这些特征可用于产品绩效分析、需求预测，或集成到推荐系统中。
+
+```python
+# -----------------------------------------
+# 3. 产品销售特征（源自行项目和产品）
+# -----------------------------------------
+product_sales = lineitem.groupBy("L_PARTKEY") \
+    .agg(
+        F_sum("L_EXTENDEDPRICE").alias("total_extended_price"),
+        F_avg("L_EXTENDEDPRICE").alias("avg_extended_price"),
+        F_count("L_ORDERKEY").alias("order_count")
+    ) \
+    .withColumnRenamed("L_PARTKEY", "part_sk")
+
+# 将产品表与销售数据连接，并使用CASE WHEN转换产品类型
+product_features = part.join(
+    product_sales,
+    part["P_PARTKEY"] == product_sales["part_sk"],
+    "left"
+).select(
+    part["P_PARTKEY"].alias("part_sk"),
+    part["P_NAME"],
+    when(col("P_TYPE").like("%ECONOMY%"), 1)
+      .when(col("P_TYPE").like("%STANDARD%"), 2)
+      .when(col("P_TYPE").like("%PROMO%"), 3)
+      .otherwise(0).alias("product_type_code"),
+    product_sales["total_extended_price"],
+    product_sales["avg_extended_price"],
+    product_sales["order_count"]
+)
+
+# 用适当类型的默认值替换空值：
+product_features = product_features.na.fill({
+    "P_NAME": "",                       # 对于字符串列，使用空字符串。
+    "total_extended_price": Decimal("0.00"),  # 对于DecimalType(25,2)，使用具有匹配精度的Decimal。
+    "avg_extended_price": Decimal("0.000000"), # 对于DecimalType(19,6)
+    "product_type_code": 0,               # 整数
+    "order_count": 0                      # 整数

+
+### 4. 供应商特征
+
+* **功能**：此部分首先按供应商键对 partsupp 表中的供应商相关数据进行聚合，计算总可用数量、总供应成本和平均供应成本等指标。然后，将这些聚合值与供应商表连接，以丰富供应商详情（名称、地址、电话）。特别注意使用与数据类型匹配的默认值处理空值。
+
+* **目标**：构建一个全面的供应商特征数据集，反映 partsupp 中的操作指标和供应商表中的供应商身份。此数据集支持下游任务，如供应商绩效评估、风险评估和供应商分类。
+
+```python

+
+## 总结与分析
+
+### 机器学习场景和数据需求
+
+* **客户细分/流失预测**：需要每位客户的特征（总消费、订单频率、平均订单价值、账户余额以及编码后的市场细分）以及地理信息（国家/地区）。
+* **销售预测**：订单日期（源自订单/行项目）的时间维度可能会在后续步骤中与聚合后的销售数据结合，以预测未来的销售情况。
+* **供应商绩效分析/产品销售预测**：通过计算聚合后的供应商指标（使用 partsupp 和供应商表）以及产品绩效（源自行项目和产品），可以构建模型来预测供应商的可靠性或评估产品销售潜力。
+
+### 特征工程细节
+
+* **聚合**：使用 groupBy 和聚合函数（sum、count、avg）从事务表（如订单）中计算指标（总销售额、订单数量等）。
+* **丰富和连接**：集成关联信息（将客户与国家和地区表连接，将 partsupp 与供应商表连接），以附加人口统计或地理信息。
+* **转换（CASE WHEN**）：使用 when 函数进行条件转换，例如将产品类型或市场细分编码为数值代码。这在机器学习模型需要数值输入时至关重要。
+* **数据清理**：应用 na.fill(0) 或其他插补方法处理缺失值，确保机器学习数据集的完整性。
+
+此代码提供了一个起点。根据具体的机器学习场景，您可能需要添加基于时间的窗口函数、更细粒度的特征拆分或特定领域的转换。祝您在探索这些特征和构建模型时一切顺利！

+# GET 命令
+
+## 概述
+
+GET 命令用于从云器 Lakehouse 的数据湖 Volume 对象中下载文件到客户端本地路径。通过该命令，用户可以轻松地将数据从云端同步到本地环境，以便进行进一步的分析和处理。要执行 GET 命令，您可以使用 [sqlline](connect-with-cli.md) 工具或 [数据库管理工具](eco_integration/dbeaver-lakehouse.md)。该命令暂不支持在 Studio 中运行。
+
+## 使用场景
+
+* 数据分析：将数据文件从云端下载到本地进行分析和挖掘。
+* 数据迁移：将数据从云端迁移到本地存储，以便在本地进行备份或迁移到其他云平台。
+* 数据恢复：从云端恢复丢失或损坏的数据到本地。
+
+## 语法
+
+```
+GET 
+    [ VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME ]
+    [ FILE 'file' ] 
+    TO 'local_path'
+    [ option_key = option_value ] ...
+```
+
+## 参数说明
+
+* `VOLUME/TABLE VOLUME/USER VOLUME`：分别指将外部 Volume、TABLE VOLUME 和 USER VOLUME 中的数据下载到本地。具体使用方式参考 [COPY INTO导出](<COPY-INTO-Location.md>)。
+* `FILE`：指定要下载的文件。
+* `local_path`：文件下载到本地的目标路径，其格式根据不同操作系统有所区别。
+
+
+## 示例
+
+1. 将表中数据下载到本地
+
+   ```
+    --将数据导出到内部user volume中
+    COPY INTO USER VOLUME SUBDIRECTORY 'tmp/' FROM TABLE mytable  file_format = (type = CSV);;
+    
+    -- 查看导出的文件
+    SHOW  USER VOLUME DIRECTORY;
+   +-------------------+------------------------------------------------------------------------------------------------------------+------+---------------------+
+   |   relative_path   |                                                    url                                                     | size | last_modified_time  |
+   +-------------------+------------------------------------------------------------------------------------------------------------+------+---------------------+
+   | tmp/part00001.csv | oss://xxxx/tmp/part00001.csv | 5    | 2024-11-14 19:44:37 |
+   +-------------------+------------------------------------------------------------------------------------------------------------+------+---------------------+
+
+    --下载文件
+    GET USER VOLUME FILE 'tmp/part00001.csv' TO  './';
+    --删除volume中文件，避免占用存储
+    REMOVE USER VOLUME FILE 'tmp/part00001.csv';
+    SHOW USER VOLUME DIRECTORY;
+   +---------------+-----+------+--------------------+
+   | relative_path | url | size | last_modified_time |
+   +---------------+-----+------+--------------------+
+   ```
+
+
+
+## 注意事项
+
+* 从外部 Volume 下载文件会产生对应云账号的对象存储下载费用。
+* GET 命令不能通过 Studio SQL 任务节点执行，但可以通过云器 Lakehouse SQLline 客户端、JDBC 客户端以及 SDK 来执行。

+# GET\_PRESIGNED\_URL 函数
+
+该函数通过输入 Volume 名称、文件的相对路径和有效时间（秒），为 Volume 中的文件生成一个预签名 URL。此功能允许应用程序访问存储在外部 Volume 中的文件。
+
+## 使用场景
+
+以下是几种访问 Volume 中文件的方法：
+
+1. 在 Web 浏览器中直接访问带有一个预签名的 URL（字符串类型）。
+2. 将 Volume 中文件的预签名 URL 发送给远程函数进行处理。
+
+## 注意事项
+
+1. 执行该函数的用户需要对 Volume 对象具有读取 (READ) 权限。
+
+2. 该函数需要从 Volume 本地的元数据系统中获取文件信息（例如 `relative_path`）。请确保刚刚导入的 Volume 对应的文件元数据已经同步到 Lakehouse 元数据系统，或使用以下命令进行刷新：
+
+   ```
+   ALTER VOLUME <volume_name> REFRESH;
+   ```
+
+3. GET\_PRESIGNED\_URL 是一个非确定性函数 (non-deterministic function)，即在给定相同输入值的情况下，每次执行的输出结果可能不同。
+
+## 语法
+
+```
+GET_PRESIGNED_URL(VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME , '<relative_file_path>', [<expiration_time>])
+```

+* **volume \<volume\_name**>**：`volume` 为固定关键字，表示后面的对象类型为 Volume；`volume_name` 为系统创建的 Volume 名称。
+* **relative\_file\_path**：相对于 Volume 指定位置的文件路径和文件名。可以通过调用 `directory` 函数获取：
+  ```
+  SELECT GET_PRESIGNED_URL(volume <volume_name>, relative_path) AS pre_signed_url
+  FROM DIRECTORY(volume <volume_name>);
+  ```
+* **expiration\_time**：生成的预签名 URL 的有效期，以秒为单位。默认值为 3600 秒（60 分钟）。
+
+## 返回值
+
+一个预签名的 URL（字符串类型）。
+
+## 使用示例
+
+以下是几个使用 GET\_PRESIGNED\_URL 函数的示例：
+
+1. 生成一个有效期为 1 小时的预签名 URL：
+
+   ```
+   SELECT GET_PRESIGNED_URL(volume hz_image_volume, 'example.jpg', 3600) AS pre_signed_url;
+   ```
+
+2. 生成一个默认有效期（1 小时）的预签名 URL：
+
+   ```
+   SELECT GET_PRESIGNED_URL(USER VOLUME, 'pangxie_pic.jpg', 3600) AS pre_signed_url;
+   ```
+
+3. 从目录中获取文件的相对路径，并生成一个预签名 URL：
+
+   ```
+   SELECT GET_PRESIGNED_URL(volume hz_image_volume, relative_path) AS pre_signed_url
+   FROM DIRECTORY(volume hz_image_volume);
+   ```
+
+> 注意：如果生成的 URL 无法访问，可能是因为生成了对象存储的内部链接。可尝试在执行 SQL 前添加以下参数后再次尝试：
+>
+> `set cz.sql.function.get.presigned.url.force.external=true;`
+>
+> 例如：
+>
+> ```
+> SET cz.sql.function.get.presigned.url.force.external=true; 
+> SELECT GET_PRESIGNED_URL(USER VOLUME, 'pangxie_pic.jpg', 3600) AS pre_signed_url;
+> ```
+
+4. 批量获取 USER VOLUME 中图片的预签名 URL
+
+   ```
+    SET cz.sql.function.get.presigned.url.force.external=true;
+    SELECT relative_path,
+    GET_PRESIGNED_URL(USER VOLUME, relative_path, 3600) AS pre_signed_url
+    FROM (
+          SELECT relative_path FROM (LIST USER VOLUME)
+    );
+    ```
+
+通过以上示例，您可以更好地了解如何在不同场景中使用 GET\_PRESIGNED\_URL 函数。请根据您的实际需求调整参数和代码。

+## 功能描述
+
+本文档介绍了如何在 Lakehouse SQL 中使用 GRANT 语句，将指定的权限授予给角色。通过该操作，角色将获得对指定资源的访问和操作权限。
+
+## Workspace 用户和角色权限管理语法
+
+### 1. 授予 Workspace 级别权限
+```SQL
+GRANT workspacePrivileges  ON WORKSPACE  workspace_name
+| workspaceObjectPriveleges ON { ROLE | SCHEMA | VCLUSTER | DATALAKE | FUNCTION  workspace_object_name
+| schemaPrivileges ON SCHEMA schema_name  
+| schemaObjectPriveleges  ON { TABLE | VIEW | MATERIALIZED VIEW } schema_object_name
+TO ROLE  rolename
+```
+- **参数说明：**
+  - `workspacePrivileges`：指定授予的 Workspace 级别权限，例如：CREATE SCHEMA, CREATE VCLUSTER。
+  - `workspace_name`：指定要授权的 Workspace 名称。
+  - `rolename`：指定要授予权限的角色名称。
+
+### 2. 授予 Workspace 对象权限
+```SQL
+GRANT workspaceObjectPriveleges ON { ROLE | SCHEMA | VCLUSTER | DATALAKE | FUNCTION } workspace_object_name TO ROLE rolename;
+```
+- **参数说明：**
+  - `workspaceObjectPriveleges`：指定授予的 Workspace 对象权限，例如：ALTER, DROP, READ METADATA, ALL [PRIVILEGES]。
+  - `workspace_object_name`：指定要授权的 Workspace 对象名称。
+  - `rolename`：指定要授予权限的角色名称。
+
+### 3. 授予 Schema 级别权限
+```SQL
+GRANT schemaPrivileges ON SCHEMA schema_name TO ROLE rolename;
+```
+- **参数说明：**
+  - `schemaPrivileges`：指定授予的 Schema 级别权限，例如：CREATE TABLE, CREATE VIEW, CREATE MATERIALIZED VIEW, ALL。
+  - `schema_name`：指定要授权的 Schema 名称。
+  - `rolename`：指定要授予权限的角色名称。
+
+### 4. 授予 Schema 对象权限
+```SQL
+GRANT schemaObjectPriveleges ON { TABLE | VIEW | MATERIALIZED VIEW } schema_object_name TO ROLE rolename;
+```
+- **参数说明：**
+  - `schemaObjectPriveleges`：指定授予的 Schema 对象权限，例如：ALTER, DROP, SELECT, INSERT, READ METADATA, ALL。
+  - `schema_object_name`：指定要授权的 Schema 对象名称。
+  - `rolename`：指定要授予权限的角色名称。
+
+## 使用示例
+
+示例 1：授予角色创建 VIRTUAL CLUSTER 权限
+```SQL
+GRANT CREATE VCLUSTER ON WORKSPACE lakehouse_public TO ROLE simple_role;
+```
+
+示例 2：授予角色修改 VIRTUAL CLUSTER 权限
+```SQL
+GRANT ALTER VCLUSTER ON VCLUSTER default TO ROLE simple_role;
+```
+
+示例 3：授予角色创建表和创建视图的权限
+```SQL
+GRANT CREATE VIEW, CREATE TABLE ON SCHEMA public TO ROLE simple_role;
+```
+
+示例 4：授予角色对指定表的查询和修改权限
+```SQL
+GRANT SELECT, ALTER ON TABLE public.my_table TO ROLE my_role;
+```
+
+示例 5：授予角色对指定视图的查询和修改权限
+```SQL
+GRANT SELECT, ALTER ON VIEW public.my_view TO ROLE my_role;
+```
+
+## ### 示例 6：授予角色对指定物化视图的查询和修改权限
+```SQL
+GRANT SELECT, ALTER ON MATERIALIZED VIEW public.my_materialized_view TO ROLE my_role;
+```
+
+通过以上示例，您可以根据实际需求为角色授予相应的权限。请注意，授予的权限应与角色的职责和工作内容相匹配，以确保数据安全和权限的合理分配。
+
+## Instance Role 授权
+
+通过 Instance Role 可授予跨工作空间的全局权限，授权对象包括用户或其他角色。
+
+### 语法说明
+
+```SQL
+-- 将 Instance Role 授予用户/角色
+GRANT INSTANCE ROLE <role_name> TO USER <user_name>;
+-- 授予 Instance Role 全局权限
+GRANT <privilege> ON WORKSPACE <workspace_name> TO INSTANCE ROLE <role_name>;
+-- 回收权限
+REVOKE <privilege> ON WORKSPACE <workspace_name> FROM INSTANCE ROLE <role_name>;
+-- 查看 Instance Role 权限
+SHOW GRANTS TO INSTANCE ROLE <role_name>;
+```
+
+#### 示例
+
+```SQL
+-- 授予用户 Instance Role
+GRANT INSTANCE ROLE inst_role TO USER lh_engine_test_01;
+-- 授予工作空间全部权限
+GRANT ALL ON WORKSPACE ws1 TO INSTANCE ROLE inst_role;
+-- 查看权限（预期含跨空间授权记录）
+SHOW GRANTS TO INSTANCE ROLE inst_role;
+-- 回收工作空间权限
+REVOKE ALL ON WORKSPACE ws1 FROM INSTANCE ROLE inst_role;
+-- 验证权限回收
+SHOW GRANTS TO INSTANCE ROLE inst_role;
+-- 授予单表权限（标准语法兼容）
+GRANT ALL ON TABLE ws1.schema.table TO INSTANCE ROLE inst_role;
+```

+## 功能概述
+
+Hive 存储连接用于访问和管理已有的 Hive 元数据服务。通过配置此连接，您可以：
+
+1. 无缝对接现有的数据仓库基础设施。
+2. 复用已构建的表结构和元数据信息。
+3. 统一管理数据目录，实现跨平台数据资产整合。
+
+这种配置方式特别适合企业在数据平台升级或整合过程中，实现平滑过渡和系统共存。您无需迁移现有数据，即可充分利用两个系统的优势。
+
+## 使用限制
+
+* 使用前请确保 Lakehouse 和 Hive 集群网络已打通。
+* 目前，云器 Lakehouse 的外部 Catalog 功能支持以下外部数据源：
+  * Hive on OSS（阿里云对象存储服务）
+  * Hive on COS（腾讯云对象存储服务）
+  * Hive on S3（AWS对象存储服务）
+  * Hive on GCS（Google云对象存储服务）
+* 同时支持读取和写入。写入格式支持 Parquet、ORC、Text 文件格式。
+
+### 创建外部 Catalog
+
+**创建 Hive Catalog 的步骤**
+
+1.  **创建存储连接**：首先需要创建一个存储连接，用于访问对象存储服务。
+2.  **创建 Catalog Connection**：使用存储连接信息和 Hive Metastore 地址创建 Catalog Connection。
+3.  **创建外部 Catalog**：使用 Catalog Connection 创建外部 Catalog，以便在数据湖中访问外部数据。
+
+#### 创建存储连接
+
+创建存储连接可参考文档 [创建STORAGE CONNECTION](aliyun_storage_connection.md)。
+
+```SQL
+CREATE STORAGE CONNECTION if not exists catalog_storage_oss
+    type OSS
+    ACCESS_ID='LTAIxxxxxxxxxxxx'
+    ACCESS_KEY='T8Gexxxxxxmtxxxxxx'
+    ENDPOINT='oss-cn-hangzhou-internal.aliyuncs.com';
+```
+
+#### 创建 Catalog Connection
+
+```SQL
+CREATE CATALOG CONNECTION if not exists catalog_api_connection
+    type hms
+    hive_metastore_uris='xxx:9083'
+    storage_connection='catalog_storage_oss';
+```

+# 自增列IDENTITY
+
+Lakehouse支持在建表时标识列，将字段定义为自增字段。
+
+配置自增序列。如下建表语句使用自增列，仅支持bigint类型：
+
+```Plain
+CREATE TABLE tablename (
+    id bigint identity
+);
+```
+
+## 语法
+
+```SQL
+IDENTITY[(seed)]
+```
+
+* seed：用于指定表中第一行的起始值。如果不指定，默认起始值为0。
+
+## 行为说明
+
+* 无法保证序列中的值是连续的（无间隙），也无法保证序列值按特定顺序分配，因为表中可能会发生并发插入。这些限制是设计的一部分，目的是提高性能，并且在许多常见情况下都是可以接受的。
+
+## 使用示例
+
+```SQL
+--创建表，包含id和col两个字段。
+CREATE TABLE identity_test
+(
+    id bigint identity (1),
+    col string
+);
+
+--在insert语句中，给col字段插入数据。
+INSERT INTO identity_test (col)
+VALUES ('1'),('2'),('3'),('4'),('5');
+--查询数据
+SELECT * FROM identity_test;
++----+-----+
+| id | col |
++----+-----+
+| 1  | 1   |
+| 2  | 2   |
+| 3  | 3   |
+| 4  | 4   |
+| 5  | 5   |
++----+-----+
+--再插入一条数据，无法保证自增连续性
+INSERT INTO identity_test (col)
+VALUES ('6');
++----+-----+
+| id | col |
++----+-----+
+| 11 | 6   |
+| 1  | 1   |

+| 4  | 4   |
+| 5  | 5   |
++----+-----+
+--查看是否含有自增列
+SHOW CREATE TABLE identity_test;
+```
+
+# 限制与约束
+
+* 暂不支持通过Ingest Service流式接口写入，仅在SQL语法层面支持IDENTITY列的写入。
+* 不支持指定步长，默认步长是1。
+* 不支持通过ALTER语句在已有表中添加自增列。
+* 不支持为外部表、动态表和物化视图设置自增列。
+* 只支持bigint类型。

+## 功能概述
+
+`INSERT INTO` 语句用于将数据插入表中。您可以为表中的每个列显式指定值，或者使用 `SELECT` 查询的结果作为插入的数据源。
+
+## 语法结构
+
+```SQL
+INSERT INTO|OVERWRITE [TABLE] table_name 
+[ PARTITION partition_spec] 
+[ (column1, column2, ...)]
+{VALUES(value1 [,...],(value2 [,...]),...) | subquery}
+
+partition_spec ::=
+    partition_column_name = partition_column_val [ , ... ]
+```
+
+## 参数详解
+
+1. **INSERT INTO**：以追加模式插入数据。
+2. **INSERT OVERWRITE**：重写目标表或目标表的某些分区。
+   * 对于分区表，将覆盖指定分区的数据。
+   * 对于非分区表，将覆盖整个表的数据。
+3. **TABLE**：（可选）关键字，用于指定目标表。
+4. **partition\_spec**：（可选）分区规范，用于指定插入数据的分区。
+   * 静态分区：直接指定分区列的值，例如 `PARTITION (dt='shanghai')`。
+   * 动态分区：系统根据 `VALUES` 或 `SELECT` 语句的值自动映射到相应分区。
+   * 如果未指定分区规范，系统将根据分区列的值自动选择分区。
+5. **column\_list**：指定要插入数据的列，确保输入查询的列顺序与表中的列顺序相匹配。
+
+## 使用指南
+
+* **数据类型匹配**：确保插入的数据类型与表定义中的列类型相匹配。
+
+* **查询结果匹配**：使用 `SELECT` 语句插入数据时，查询返回的列数量和顺序应与目标表的列相匹配。
+
+* **分区规范**：在分区表中插入数据时，如果未指定分区规范，系统将根据分区列的值自动选择分区。确保插入的数据中包含有效的分区值。
+
+* **INSERT OVERWRITE**：使用此语句插入数据时，确保目标表或分区存在，否则操作将失败。
+
+* **数据检查**：执行插入操作前，检查数据类型和列数量是否与目标表匹配，以避免数据插入错误。**特别注意的是，Apache Hive要求分区列是最后一个位置。没有这种强制要求，因此加列的时候特别注意：按照原来Hive方式加列可能会将列加到最后一个位置，所以加列的时候必须指定位置。否则会造成数据错误。**
+
+* **自动分区处理**：当使用分区字段为函数的表时，无需指定 `PARTITION` 子句，系统会自动根据函数返回值处理分区。
+
+* **大量数据导入**：在lakehouse环境中，不推荐使用 `INSERT INTO...VALUES` 方式导入大量数据，这种方式更适合测试场景。对于大量数据导入，请参阅[数据导入指南](data-load-summary.md)。
+
+## 使用示例
+
+**普通表插入**
+假设`test` 表包含两个列`c1`, `c2`。
+
+1. 向`test`表中导入一行数据
+
+```
+INSERT INTO test VALUES (1, 2);
+INSERT INTO test (c1, c2) VALUES (1, 2);
+INSERT INTO test (c1) VALUES (1);
+```
+
+其中第一条、第二条语句是一样的效果。在不指定目标列时，使用表中的列顺序来作为默认的目标列。 第三条语句未指定`c2`则使用null来填充，如果`c2`列有默认值则使用默认值填充。
+
+2. 向`test`表中一次性导入多行数据
+
+```
+INSERT INTO test VALUES (3, 5), (5, 5 + 2);
+INSERT INTO test (c1, c2) VALUES (6, 7), (6, 7* 2);
+INSERT INTO test (c1) VALUES (1), (3);
+```
+
+其中第一条、第二条语句效果一样，向`test`表中一次性导入两条数据。第三条语句未指定`c2`则使用null来填充，如果有默认值则使用默认值，向`test`表中导入两条数据。
+
+3. 向 `test` 表中导入一个查询语句结果
+
+```
+INSERT INTO test SELECT * FROM test2;
+INSERT INTO test (c1, c2) SELECT * from test2;
+```
+
+4. 分区表插入数据
+
+```SQL
+-- 创建分区表
+CREATE TABLE sales (
+  id BIGINT,
+  name VARCHAR(64),
+  dt STRING
+)
+PARTITIONED BY (dt);
+
+-- 插入单行数据
+INSERT INTO sales VALUES (1001, 'Alice', '2021-01-01');
+
+-- 插入多行数据
+INSERT INTO sales VALUES (1002, 'Bob', '2021-01-02'), (1003, 'Charlie', '2021-01-03');
+
+-- 指定分区插入数据
+INSERT INTO sales PARTITION (dt='2021-01-04') (id, name) VALUES (1004, 'David');
+
+-- 使用 SELECT 语句插入数据
+INSERT INTO sales SELECT * FROM sales_temp;
+```
+
+5. 插入数据时指定列顺序
+
+```SQL
+-- 假设表结构为 (id, name, dt)
+CREATE TABLE sales (id BIGINT, name VARCHAR(64), dt STRING);
+
+-- 插入数据时仅指定 id 和 name 列。未指定的列则会显示null
+INSERT INTO sales (id, name) VALUES (1005, 'Eve');
++------+------+----+
+|  id  | name | dt |
++------+------+----+
+| 1005 | Eve  |    |
++------+------+----+
+```
+
+6. 使用INSERT OVERWRITE插入数据
+
+```SQL
+-- 创建分区表
+CREATE TABLE sales (
+  id BIGINT,
+  name VARCHAR(64),
+  dt STRING
+)
+PARTITIONED BY (dt);
+
+-- 插入单行数据
+INSERT OVERWRITE sales VALUES (1001, 'Alice', '2021-08-01');
+
+-- 插入多行数据
+INSERT OVERWRITE sales VALUES (1002, 'Bob', '2021-08-02'), (1003, 'Charlie', '2021-08-03');
+
+-- 指定分区插入数据
+INSERT OVERWRITE sales PARTITION (dt='2021-08-04') VALUES (1004, 'David', '2021-08-04');
+
+-- 使用查询结果插入数据
+INSERT OVERWRITE sales SELECT * FROM sales_temp;
+```
+
+7. 插入不同的数据类型
+
+```
+CREATE TABLE lakehouse_datatype(
+  `c_bigint` bigint,
+  `c_boolean` boolean,
+  `c_binary` binary,
+  `c_char` char(1),
+  `c_date` date,
+  `c_decimal` decimal(20,6),
+  `c_double` double,
+  `c_float` float,

+# INTERVAL
+
+# INTERVAL 数据类型
+
+Lakehouse 提供了 INTERVAL 数据类型，用来表示两个日期或时间之间的时间间隔。本文为您介绍 INTERVAL 类型的使用方法和语法。
+
+## 使用说明
+
+INTERVAL数据类型支持两种类型的间隔：
+
+* INTERVAL\_YEAR\_MONTH：表示年月间隔，使用YEAR和MONTH字段存储时间间隔。
+* INTERVAL\_DAY\_TIME：表示日间间隔，使用包括小数秒在内的天、小时、分钟和秒存储间隔。
+
+### INTERVAL\_YEAR\_MONTH
+
+#### 语法格式
+

+
+## interval 类型的运算
+
+INTERVAL 类型可以与数值类型、日期时间类型进行一些简单的算术运算。
+
+```JavaScript
+> SELECT INTERVAL 4 DAY * 2, INTERVAL 4 DAY  / 2;
+8 00:00:00.000000000    2 00:00:00.000000000
+
+> SELECT timestamp '2019-10-15' - timestamp '2019-10-14', date '2020-10-15' - date '2019-10-14';
+1 00:00:00.000000000    367 00:00:00.000000000
+
+> SELECT timestamp '2020-10-10' + INTERVAL 1 DAY, date '2020-10-10' + INTERVAL 1 MONTH;
+2020-10-11 00:00:00     2020-11-10
+
+> SELECT INTERVAL 1 DAY < INTERVAL 2 DAY;
+true
+```
+
+## interval 类型写法更宽松
+
+```
+SELECT    interval 7 week;
++--------------------------------------+
+| INTERVAL '49 00:00:00' DAY TO SECOND |
++--------------------------------------+
+| 49 00:00:00.000000000                |
++--------------------------------------+
+
+```

+
+```
+SELECT    'interval 7 week';
++-------------------+
+| 'interval 7 week' |
++-------------------+
+| interval 7 week   |
++-------------------+
+
+```
+
+INTERVAL 数字可以写到字符串中
+
+```
+SELECT    interval '7' week;
++--------------------------------------+
+| INTERVAL '49 00:00:00' DAY TO SECOND |
++--------------------------------------+
+| 49 00:00:00.000000000                |
++--------------------------------------+
+
+```
+
+数字和时间单位可以写在整个字符串中
+
+```
+SELECT    interval '7 week';

+# 将数据从阿里云数据湖摄取到云器 Lakehouse 的三层数据仓库中
+
+## 关于三层数据仓库（3 Layer Data Warehouse）
+
+在现代数据湖仓架构中，三层数据仓库（3 Layer Data Warehouse）通常分为Bronze层、Silver层和Gold层。这种架构提供了一种系统化的方法来管理不同状态的数据，从原始数据到高质量数据。
+
+### 1. Bronze层（原始数据层）
+
+Bronze层是数据仓库的最底层，用于存储从各种数据源提取的原始数据。这些数据未经处理，保留了数据的原始形式。
+
+**特点**：
+
+* **数据状态**：原始、未经处理的数据。
+* **数据来源**：各种数据源（数据库、日志、文件等）。
+* **目的**：提供原始数据的备份和数据追溯，确保数据的完整性和可审计性。
+
+### 2. Silver层（清洗和转换层）
+
+Silver 层用于存储经过清洗和转换的数据。这一层的数据经过 ETL（Extract, Transform, Load）流程处理，去除了噪声和冗余，转化为结构化和标准化的数据格式。
+
+**特点**：
+
+* **数据状态**：经过清洗和标准化处理的数据。
+* **数据操作**：清洗、去重、数据转换和整合。
+* **目的**：提供高质量、结构化的数据，以便进一步处理和分析。
+
+### 3. Gold层（业务信息层）
+
+Gold 层是面向分析和业务的重要数据层，存储经过进一步优化和聚合的数据。这一层的数据通常支持商业智能（BI）、数据分析和报告等应用。
+
+**特点**：
+
+* **数据状态**：高质量、聚合和优化过的数据。
+* **数据操作**：数据聚合、多维分析、数据建模。
+* **目的**：支持数据分析、商业智能和决策支持，提供优化的数据视图。
+
+### 三层数据仓库架构的优势
+
+* **数据管理效率**：分层存储和处理数据，使得管理和维护更加便捷。
+* **数据质量提升**：清洗和转换层保证了数据的一致性和准确性。
+* **高效数据访问**：业务信息层经过优化的数据结构，提升了查询性能。
+* **灵活性强**：适应不同的业务需求，支持各种数据源的整合和处理。
+
+通过这种三层架构，企业可以更有效地管理和分析数据，确保数据从采集到分析的各个阶段都得到妥善处理和优化。
+
+### 需要什么
+
+* [云器Lakehouse](https://www.yunqi.tech/)账户
+* 本指南的[Github代码库](https://github.com/yunqiqiliang/clickzetta_quickstart/tree/main/QuickStarts_Data_from_Alicloud_Datalake_to_3Layer_Clickzetta_Data_Warehouse)
+* 访问阿里云OSS的AK信息
+
+## 基于云器Lakehouse的实现方案
+
+本方案是基于云器 Lakehouse 创建一个多层数据仓库架构，其中有三层：用于数据提取的 Bronze 层、用于清理和转换数据的 Silver 层以及用于业务级聚合和数据修改的 Gold 层。
+
+^

+
+###
+
+### Bronze层
+
+Bronze层专注于从阿里云对象存储OSS到云器Lakehouse的数据摄取。这是通过创建数据湖 Connection 和 External Volume，以及 Lakehouse Pipe、Table Stream 来完成的，该阶段在 External Volume 中指定阿里云 OSS 中数据的位置。使用External Volume，可以使用Lakehouse Pipe自动将数据实时摄入到Lakehouse的表中。
+
+最后，为每个表创建一个 Table Stream，以跟踪和保存对表所做的任何更改。这些流可用于识别 Bronze 层表中的更改并对 Silver 层中的相应表进行更新。
+
+### Silver层
+
+Silver层专注于数据清理和转换。它使用来自Bronze层的原始数据，并对其进行转换以满足公司的需求。这些转换包括清理缺失或异常值、数据验证以及删除未使用或不重要的数据。
+
+#### 客户数据清洗与转换
+
+| 转型     | 细节                      |
+| ------ | ----------------------- |
+| 电子邮件验证 | 确保电子邮件不为空               |
+| 客户类型   | 将客户类型标准化为“常规”、“高级”或“未知” |
+| 年龄验证   | 确保年龄在 18 至 120 岁之间      |
+| 性别标准化  | 将性别分类为“男”、“女”或“其他”      |
+| 总购买量验证 | 确保总购买量是一个数字，如果无效则默认为 0  |
+
+#### 产品数据清洗与转换
+
+| 转型     | 细节             |
+| ------ | -------------- |
+| 价格验证   | 确保价格为正数        |
+| 库存数量验证 | 确保库存数量非负       |
+| 评级验证   | 确保评分在 0 到 5 之间 |
+
+#### 订单数据清洗与转换
+
+| 转型       | 细节          |
+| -------- | ----------- |
+| 金额验证     | 确保交易金额大于 0  |
+| 交易 ID 验证 | 确保交易 ID 不为空 |
+
+### Gold层
+
+Gold层旨在利用Silver层的转换数据来创建可用于业务分析的动态表。例如，DT\_RegionAnalysis是一个结合所有 3 个表的统一数据视图，用于分析不同地区的销售业绩并确定销售额最好的地区。
+除了本项目所展示的简单动态表之外，还可以在Gold层进行许多额外的分析。

+# JDBC驱动
+
+## Java环境需求
+
+Clickzetta Lakehouse JDBC 驱动需要 Java 1.8 版本或更高版本。请确保您的开发环境已安装并配置了相应版本的Java。
+
+## JDBC驱动下载
+
+您可以通过以下两种方式下载并使用Clickzetta Lakehouse JDBC驱动：
+
+1. 通过Maven依赖
+   在项目的 `pom.xml` 文件中添加以下依赖代码：
+   ```xml
+   <dependency>
+     <groupId>com.clickzetta</groupId>
+     <artifactId>clickzetta-java</artifactId>
+     <version>${version}</version>
+   </dependency>
+   ```
+2. 直接下载 SDK Jar 包。在 Maven 仓库页面可以找到对应版本的 Jar 包并下载。
+
+* [下载地址一](https://central.sonatype.com/artifact/com.clickzetta/clickzetta-java/versions)
+* [下载地址二](https://mvnrepository.com/artifact/com.clickzetta/clickzetta-java)
+
+## 配置JDBC驱动
+
+要使用 Clickzetta Lakehouse JDBC 驱动连接到 Clickzetta Lakehouse，您需要按照以下步骤进行配置：
+
+### JDBC驱动类
+
+在您的 JDBC 应用程序中，使用 `com.clickzetta.client.jdbc.ClickZettaDriver` 类加载驱动。
+
+### JDBC连接字符串
+
+使用 JDBC 驱动连接到 Clickzetta Lakehouse 时，JDBC 连接字符串的语法格式如下：
+
+```
+jdbc:clickzetta://<instance_name>.<region_id>.api.clickzetta.com/<workspace_name>?<connection_params>
+```
+
+* 连接参数说明：
+
+  * `<instance_name>`：Lakehouse 服务实例名称。在开通指定 Region 的 Lakehouse 服务实例时，系统会自动分配实例名称。您可以在 Clickzetta 产品控制台页面找到 Lakehouse 实例名称。
+
+    ![](.topwrite/assets/image_1690453632319.png)
+
+  * `<region_id>`：服务实例所在的云厂商及区域的代码，如：cn-shanghai-alicloud。所有region\_id详见[云服务和地域](Supported_Cloud_Platforms.md)。
+
+  * `<workspace_name>`：工作空间名称。
+
+  * `<connection_params>`：支持使用 `=` 格式定义参数，多个参数之间用 `&` 符号分隔。常用参数如下表所示：
+
+| 参数             | 取值                                                                     |
+| -------------- | ---------------------------------------------------------------------- |
+| username       | Clickzetta登录用户名                                                        |
+| password       | 登录用户密码                                                                 |
+| schema         | 指定默认连接的schema，可选                                                       |
+| virtualCluster | 配置JDBC连接默认使用的虚拟集群，可选。如不选择指定，需要连接后通过SQL命令`use vcluster <vc_name>`指定方可使用 |
+| use\_http=true | 是否使用 HTTP 协议，默认为 HTTPS。当使用 Private Link 连接时需要指定该参数。                          |
+
+#### 连接串示例

+# 连接MindsDB实现基于ML和LLM的数据分析
+
+步骤概述：
+
+1. 在云器Lakehouse的“数据源”里增加MySQL类型的数据源，通过MySQL协议连接到[MindsDB](mindsdb.md)。
+2. 在云器Lakehouse中新建“JDBC脚本”任务类型，数据源选择在第一步新建的MindsDB数据源。
+3. 这样，就可以在云器Lakehouse中使用MySQL语法来操作和管理MindsDB，并对云器Lakehouse中的数据，通过MindsDB管理的模型（包括传统机器学习模型和LLM）进行各种预测分析。
+4. 与SQL任务一样，可以直接对JDBC任务进行周期调度和运维，并通过设置任务依赖实现与其他任务的工作流编排。
+
+## 新建MindsDB连接
+
+新建连接前，请确保您的MindsDB已开启MySQL服务端口47335。

+# JOIN
+
+Join 是指在 SQL 语句中使用 JOIN 子句将两个或多个表的数据根据某些条件进行合并的操作。它可以让您从不同的数据源中获取相关信息，并且可以在合并之前或之后对数据进行一些转换或处理。Join 的语法如下：
+
+```SQL
+left_table_reference { 
+[ join_type ] JOIN right_table_reference join_criteria |
+ NATURAL  JOIN right_table_reference | 
+ CROSS JOIN right_table_reference } 
+ --join类型
+join_type::= 
+     { [ INNER ] | LEFT [ OUTER ] | [ LEFT ] SEMI | RIGHT [ OUTER ] | FULL [ OUTER ] | [ LEFT ] ANTI | CROSS } 
+--join条件
+join_criteria::=
+     { ON boolean_expression | USING ( column_name [, ...] ) }
+```
+
+其中，`left_table_reference` 是指 JOIN 的左表，`right_table_reference` 是指 JOIN 的右表，`join_type` 是指 JOIN 的类型，`join_criteria` 是指 JOIN 的条件。
+
+## Join的类型
+
+Join 的类型有以下几种：
+
+* **INNER JOIN**：返回两个表中满足 JOIN 条件的数据行，也就是两个表的交集。这是默认的 JOIN 类型。
+* **LEFT \[OUTER] JOIN**：返回左表的所有数据行，以及右表中满足 JOIN 条件的数据行，如果右表中没有匹配的数据行，则用 NULL 填充。这也叫做左外连接。
+* **RIGHT \[OUTER] JOIN**：返回右表的所有数据行，以及左表中满足 JOIN 条件的数据行，如果左表中没有匹配的数据行，则用 NULL 填充。这也叫做右外连接。
+* **FULL \[OUTER] JOIN**：返回两个表的所有数据行，如果某个表中没有匹配的数据行，则用 NULL 填充。这也叫做全外连接。
+* \[**LEFT] SEMI JOIN**：返回左表中满足 JOIN 条件的数据行，不返回右表的数据。这也叫做左半连接。
+* \[**LEFT] ANTI JOIN**：返回左表中不满足 JOIN 条件的数据行，不返回右表的数据。这也叫做左反连接。
+* **CROSS JOIN**：返回两个表的笛卡尔积，也就是两个表所有可能的组合。
+* **NATURAL JOIN**：根据两个表中同名的列进行隐式的等值连接，不需要指定 JOIN 条件。
+
+## Join的条件
+
+Join 的条件有以下两种：
+
+* **ON boolean_expression**：指定一个返回布尔值的表达式，用来判断两个表的数据行是否匹配。如果结果为真，则认为匹配。JOIN 条件不支持子查询。
+* **USING (column_name** [, …])：指定一个或多个列名，用来进行等值连接。这些列名必须同时存在于两个表中。JOIN 条件不支持子查询。
+
+## Join 的使用示例
+
+以下是一些使用 JOIN 的 SQL 语句的示例，以及它们的输出结果。假设我们有以下两个表：
+
+```SQL
+create table students(name string,class string);
+INSERT INTO students (name, class) VALUES
+('Alice', 'A'),
+('Bob', 'B'),
+('Carol', 'A'),
+('David', 'C');
+create table scores(name string,score int);
+INSERT INTO scores (name, score) VALUES
+('Alice', 90),
+('Bob', 80),
+('Carol', 85),
+('David', 95);
+```
+
+### INNER JOIN

+ON students.name = scores.name;
+
++-------+-------+-------+
+| name  | class | score |
++-------+-------+-------+
+| Carol | A     | 85    |
+| Bob   | B     | 80    |
+| David | C     | 95    |

+ON students.name = scores.name;
++-------+-------+-------+
+| name  | class | score |
++-------+-------+-------+

++-------+-------+-------+
+```
+
+### FULL \[OUTER] JOIN
+
+* 查询：使用 FULL JOIN 将两个表的数据合并，根据姓名进行匹配，显示每个学生的姓名、班级和成绩，如果某个学生没有班级或成绩，则用 NULL 填充。

+# JSON数据格式简介
+
+JSON（JavaScript Object Notation）是一种轻量级、易于阅读和编写的半结构化数据格式。它基于JavaScript的一个子集，但是JSON是独立于语言的，许多编程语言都有JSON数据格式的解析和生成代码。JSON格式使用文本表示简单的数据结构，如对象、数组、字符串、数字和布尔值。JSON格式具有良好的可读性和简洁性，使其成为理想的数据交换格式。
+
+# LakeHouse中的JSON类型
+
+在LakeHouse中，JSON类型的数据可以高效地存储和查询。JSON数据在LakeHouse中会被解析，并根据数据的实际结构进行优化存储。以下是LakeHouse中JSON类型的一些特点：
+
+1. 查询性能：使用JSON类型相比于String类型在查询性能上有明显优势，因为LakeHouse会对JSON数据进行列裁剪，减少不必要的数据扫描。
+2. 数据重排：解析过程中，JSON对象的数据可能会被重新排序，因此输入和输出的JSON数据可能在键的顺序上不一致。
+3. 数字解析：解析JSON数字时，LakeHouse会优先尝试将其解析为bigint类型。如果数字超出bigint的范围，则会将其解析为double类型。需要注意的是，double类型可能会有精度损失。
+4. 错误处理：使用函数解析JSON数据时，LakeHouse会进行校验。对于非法的JSON字符串，会返回NULL值；而在声明JSON常量时，非法的JSON字符串会导致错误。
+
+此外，LakeHouse在写入过程中会根据实际的JSON Schema，将出现频次高的字段按照列存储的方式存储，以提高存储和查询效率。例如：
+
+```SQL
+CREATE TABLE json_table AS
+SELECT  parse_json(s) as j
+FROM VALUES
+('{"id": 1, "value": "200"}'),
+('{"id": 2, "value": "300"}'),
+('{"id": 3, "value": "400", "extra": 1}'),
+('{"value": "100"}') as t(s);
+```
+
+1. 对于上面的数据，LakeHouse 检测出 id 和 value 出现频次高，分别适合用 bigint 和 string 类型列式存储，则会在内部以类似 struct\<id:bigint, value:string> 的结构存储。在后续的查询过程中，如果只读取id字段且转换为bigint，如`SELECT json_extract_bigint(j, '$.id')`，则可以直接按列读取 id 字段，并消除类型转换的开销。
+2. 对于出现频次低的 extra 字段，则保留 json 结构且用更加紧凑的表示存储，避免产生过于稀疏的数据。
+
+**限制**
+
+* 不支持对JSON类型的比较操作，也不支持对JSON类型进行`ORDER BY`、`GROUP BY`或作为`JOIN`的key等。
+* 不支持作为cluster key、primary key、partition key
+* JSON字符串最大长度为16 MB。批量、实时导入时对字段进行长度校验。如果您导入数据时有大于16MB的数据您可以修改表的Properties来修改如下将json长度设置为32MB
+```
+ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.json.bytes"="33554432");
+```
+
+
+## 创建JSON列的表
+
+要创建包含JSON类型列的表，可以使用以下SQL语句：
+
+```sql
+CREATE TABLE json_example
+(
+    id bigint,
+    data json
+);
+```
+
+## 构建JSON数据
+
+### JSON常量
+
+在SQL查询中，可以使用JSON常量来表示JSON数据。例如：
+
+```sql
+SELECT
+JSON 'null',
+JSON '1',
+JSON '3.14',
+JSON 'true',
+JSON 'false',
+JSON '{"id":11,"name":"Lakehouse"}',
+JSON '[0, 1]';
+
+-- !query output
++-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
+| JSON 'null' | JSON '1' | JSON '3.14' | JSON 'true' | JSON 'false' | JSON '{"id":11,"name":"Lakehouse"}' | JSON '[0, 1]' |
++-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
+| null        | 1        | 3.14        | true        | false        | {"id":11,"name":"Lakehouse"}        | [0,1]         |
++-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
+```
+
+
+### 语法
+
+```SQL
+--键名访问JSON对象中的字段
+json_column['key']['key']...
+--通过索引访问JSON数组中的元素
+json_array[index]
+```
+
+**参数说明**
+
+* json\_column:表示一个JSON字段，类型为JSON对象。通过键名（`key`），指定为字符串，来定位并检索JSON对象内的特定数据字段。使用单个方括号`[]`可以访问对象的一级字段；而嵌套使用双方括号`[][]`则能够深入检索对象的二级或更深层次的字段。
+* json\_array:数组类型的JSON，用来根据index访问 JSON array的元素，起始值为0

+```
+
+
+
+### 使用函数
+
+### 使用函数(将STRING格式的JSON转化为字符串)
+
+`parse_json`函数可以将String类型的JSON字符串解析为JSON类型。例如：
+
+```SQL
+SELECT parse_json(s) is null, parse_json(s)
+FROM VALUES ('null'),
+            ('1'),
+            ('3.14'),
+            ('true'),
+            ('false'),
+            ('{"id":11,"name":"Lakehouse"}'),
+            ('[0, 1]'),
+            (''),
+            ('invalid') as t(s);
++-------------------------+------------------------------+
+| (parse_json(s)) IS NULL |        parse_json(s)         |
++-------------------------+------------------------------+
+| false                   | null                         |
+| false                   | 1                            |
+| false                   | 3.14                         |
+| false                   | true                         |
+| false                   | false                        |
+| false                   | {"id":11,"name":"Lakehouse"} |
+| false                   | [0,1]                        |
+| true                    | null                         |
+| true                    | null                         |
++-------------------------+------------------------------+
+```
+
+* 如果parse_json的参数为非法json字符串，则返回SQL null，is null的结果为true
+* 如果输入字符串为`'null'`，则它会被解释为JSON null值，is null的结果为false
+
+### json_array/json_object
+
+类似array/named\_struct，可以根据已有的数据构造出对应的json类型
+
+```SQL
+SELECT json_array(), json_array(NULL),json_array(NULL::int, 1, TRUE, FALSE, NULL::int, "a", 1.2, 1.3d);
++----------------+--------------------+--------------------------------------------------------------------------------------+
+| `json_array`() | `json_array`(NULL) | `json_array`(CAST(NULL AS int), 1, true, false, CAST(NULL AS int), 'a', 1.2BD, 1.3d) |
++----------------+--------------------+--------------------------------------------------------------------------------------+
+| []             | [null]             | [null,1,true,false,null,"a","1.2",1.3]                                               |
++----------------+--------------------+--------------------------------------------------------------------------------------+
+
+SELECT json_object(), json_object('k', NULL), json_object('k1', json_array(1, "a"), "k2", array(1, 2, 3));
+-- !query output
++-----------------+--------------------------+-------------------------------------------------------------------+
+| `json_object`() | `json_object`('k', NULL) | `json_object`('k1', `json_array`(1, 'a'), 'k2', `array`(1, 2, 3)) |
++-----------------+--------------------------+-------------------------------------------------------------------+
+| {}              | {"k":null}               | {"k1":[1,"a"],"k2":[1,2,3]}                                       |
++-----------------+--------------------------+-------------------------------------------------------------------+
+```
+
+## 类型转换
+
+在LakeHouse中，可以使用`::json`或`CAST`函数将其他类型转换为JSON类型。以下是一些类型转换的例子：
+| Json       | SQL           |
+| ---------- | ------------- |
+| Object     | Struct        |
+| Array      | Array         |
+| String     | string        |
+| Number     | bigint/double |
+| true/false | bool          |
+| Null       | 无对应类型         |
+| 无对应类型      | binary        |
+
+* 不存在于表格中的类型转换，会先将其转换为可以转换的类型（大多数情况为string类型），再转换为目标类型，例如cast(1.2 as json) 1.2为decimal类型，会先转换为string类型，进一步转换为json类型，结果是JSON '"1.2"'，而不是JSON '1.2'。
+* 需要注意的是cast(string as json)的语义和parse\_json(string)的语义并不一致,parse\_json 会尝试将 JSON 字符串解析成 JSON 对象，如果JSON格式不正确，则会生成 NULL而cast(string to json)**会将字符串整体当做JSON中的string类型,所以如果您是一个json格式字符串转化时应该使用parse_json**

++-------------------+--------------------+-------------------+-------------------+-------------------------+--------------------+-----------------+-----------------------+
+```
+
+需要注意的是，`cast(string as json)`和`parse_json(string)`的语义并不一致。`parse_json`会尝试将JSON字符串解析成JSON对象，如果JSON格式不正确，则会生成NULL；而`cast(string to json)`会将字符串整体当做JSON中的string类型。
+
+```SQL
+SELECT parse_json(s), s::json, s::json::string
+FROM VALUES ('{"id":11, "name": "Lakehouse"}') as t(s);
++------------------------------+----------------------------------------+---------------------------------+
+|        parse_json(s)         |            CAST(s AS json)             | CAST(CAST(s AS json) AS string) |
++------------------------------+----------------------------------------+---------------------------------+
+| {"id":11,"name":"Lakehouse"} | "{\"id\":11, \"name\": \"Lakehouse\"}" | {"id":11, "name": "Lakehouse"}  |
++------------------------------+----------------------------------------+---------------------------------+
+```
+
+# 使用SDK（igs/bulkload）写入JSON
+
+Lakehouse 支持给 JSON 类型的列写入 String 类型的字符串，系统在导入的时候会自动将字符串解析成 JSON 类型，如果用户输入了不符合 JSON 规范或者 CZ 不支持的 JSON 字符串，系统会报错并停止导入。
+
+# 导出JSON数据
+
+Lakehouse 支持以字符串的形式导出 JSON 数据。
+
+# 查询JSON数据
+
+查询JSON数据需要使用`json_extract`系列函数，通过JSON path获取需要的数据。以下是一些查询JSON数据的例子：
+
+* json\_extract
+* json\_extract\_boolean
+* json\_extract\_float
+* json\_extract\_double
+* json\_extract\_int
+* json\_extract\_bigint
+* json\_extract\_string
+* json\_extract\_date
+* json\_extract\_timestamp
+
+### json path规范
+
+json\_extract的第二个参数为json path，可以参考[json path规范](<https://goessner.net/articles/JsonPath/>)
+
+* "$"表示根元素
+* ".key"或者"\['key']" 用来查找json object中的key。特殊的，"\[\*]"表示获取所有的value,要求必须是单引号
+* "\[index]" 用来根据index访问 json array的元素，起始值为0。特殊的，"\[\*]"表示所有的元素
+
+```SQL
+SELECT json_extract(j, "$[0]"),
+       json_extract(j, "$[1]"),
+       json_extract(j, "$[*]")

+## 功能概述
+
+> **【预览发布】** 本功能当前处于公开预览阶段。
+
+本文主要介绍如何在 SQL 中创建与 Kafka 消息队列系统连接的外部表。通过定义外部表，可以方便地从 Kafka 中读取数据流，并将这些数据作为表进行查询和分析。
+
+## 创建存储连接
+
+首先，需要创建一个存储连接，用于连接到 Kafka 服务器。目前不支持需要客户端证书的连接方式。
+
+### 语法
+
+```SQL
+CREATE STORAGE CONNECTION connection_name
+    TYPE kafka
+    BOOTSTRAP_SERVERS = ['server1:port1', 'server2:port2', ...]
+    SECURITY_PROTOCOL = 'PLAINTEXT';
+```
+
+### 参数说明
+
+* **connection_name**: 连接的名称，用于后续引用。
+* **TYPE**: 连接类型，此处为 `kafka`。
+* **BOOTSTRAP_SERVERS**: Kafka 集群的地址列表，格式为 `['host1:port1', 'host2:port2', ...]`。
+* **SECURITY_PROTOCOL**: 安全协议，可以是 `PLAINTEXT` 等。
+
+### 示例
+
+```SQL
+CREATE STORAGE CONNECTION test_kafka_conn
+    TYPE kafka
+    BOOTSTRAP_SERVERS = ['47.99.48.62:9092']
+    SECURITY_PROTOCOL = 'PLAINTEXT';
+```

+# 云器 Lakehouse 基本概念
+
+欢迎使用云器 Lakehouse！本章节将为您详细介绍云器 Lakehouse 中的基本概念，帮助您更好地理解和使用本产品。
+
+## 账户（Account）
+
+云器的账户代表与云器公司建立商业关系的组织或个人（一般为企业账户），涵盖账户注册、服务开通等行为。账户是您使用云器产品服务、付费、获取服务支持的基本实体对象。注册时，系统会自动生成全局唯一的账户名，作为您在云器产品中的唯一标识。
+
+* 账户负责充值、出账单、费用支付以及订购/变更云器产品；
+* 所有企业或个人在云器产品上开通的服务实例及其资源对象都归属于特定账户。
+
+## 账户 URL
+
+每个账户都有一个唯一的账户 URL，用于访问管理中心。您需要使用该账户下的有效用户名和密码登录。账户 URL 的格式为：`<account_name>.accounts.clickzetta.com`。例如，以下链接中的 `0256c297` 即为账户名称：`0267c297.accounts.clickzetta.com`。
+
+## 用户（User）
+
+在账户注册成功后，您可以创建多个用户共同使用同一个账户内的资源。不同用户间可以通过权限控制分配可使用的数据和资源。
+
+## 服务实例（Lakehouse Instance）
+
+Lakehouse 服务实例是云器 Lakehouse 产品服务的载体。开通 Lakehouse 服务时，您需要根据指定的云服务商和地域，在您的账户下创建生成服务实例。一个账户下可以创建一个或多个服务实例（当前阶段默认开放单个服务实例的创建）。
+
+服务实例内采用统一元数据管理数据对象、计算资源、作业任务，并在统一权限体系下使用数据集成、开发调度、运维监控、数据目录等工具进行应用构建和数据管理。服务实例具备区域属性，其计算、数据和其他服务资源均在此云服务商的区域内。不同服务实例间默认相互隔离。
+
+![示意图](![](.topwrite/assets/Lakehouse服务实例.png =640))

+
+## Schema
+
+在工作空间内，Schema 是一组数据库对象的命名空间，包括表、视图等。您可以在一个工作空间内包含多个命名各异的 Schema 对象。
+
+## 表（Table）
+
+表是格式化的二维数据表格。
+
+## 视图（View）
+
+视图是一种虚拟存在的表，不在数据库中实际存在。在使用时，视图会动态生成。
+
+## 物化视图（Materialized View）
+
+物化视图是一种特殊的视图，与普通视图不同，物化视图在数据库中实际存在，并占用存储资源。详见[此文档](materialized_ddl.md)。

+
+## 运维中心
+
+运维中心提供对任务和实例的运维管理操作。它集中管理手动触发执行的任务、周期调度的任务及其对应的实例。详见[此文档](task-instance-maintenance.md)。
+
+## 数据目录
+
+数据目录是连接数据提供者和数据消费者的桥梁。它基于表的元数据信息构建，并提供全局检索和过滤功能，便于快速查找表和查看详情，为数据消费提供协助。详见[此文档](data_catalog.md)。
+
+## 工作流（Workflow）
+
+工作流是由一个或多个通过依赖关系连接的任务组成的数据加工作业流。工作流指定了任务的运行环境和资源。作业可以按需执行、周期性执行或被事件触发执行。
+
+## 工作流实例（Workflow Instance）
+
+当工作流任务被触发执行时，会生成工作流实例。工作流实例包含实例化的时间戳和任务状态，由调度系统根据触发条件创建。
+
+## 任务（Task）

+## LATERAL VIEW
+
+`LATERAL VIEW` 子句与生成器函数（如 EXPLODE、POSEXPLODE 等）结合使用，可以生成一个或多个包含行的虚拟表。该子句允许用户对输入的数组或映射进行操作，并将结果展开为独立的行。
+
+## 语法格式
+
+```
+SELECT ...
+FROM table_reference 
+LATERAL VIEW [OUTER] generator_function [ alias ] AS column_identifier [, ...]
+```
+
+## 参数说明
+
+* **OUTER**：可选参数。如果指定了 `OUTER` 关键字，当输入数组或映射为空或为 Null 时，将返回 Null 值。
+* **generator\_function**：生成器函数，如 EXPLODE、POSEXPLODE 等。
+* **alias**：可选参数。为 generator\_function 指定的别名。
+* **column\_identifier**：列出列别名，用于 `generator_function` 输出的行。列标识符的数量必须与生成器函数返回的列数相匹配。
+
+## 使用示例
+
+**准备数据**
+
+```
+CREATE TABLE employees(id int,name string,skills array<string>);
+INSERT INTO employees (id, name, skills) VALUES
+(1, 'John Doe', ['Java', 'Python', 'SQL']),
+(2, 'Jane Smith', ['C++', 'Hadoop', 'SQL']),
+(3, 'Bob Johnson', ['Python', 'Docker']);
+```
+
+**示例 1：使用 EXPLODE 函数**
+假设我们有一个名为 `employees` 的表，其中包含一个名为 `skills` 的数组类型的字段，我们想要将每个员工的技能拆分成单独的行。
+
+```
+SELECT e.id, e.name, s.skill
+FROM employees e
+LATERAL VIEW EXPLODE(e.skills) s AS skill;
++----+-------------+--------+
+| id |    name     | skill  |
++----+-------------+--------+
+| 1  | John Doe    | Java   |
+| 1  | John Doe    | Python |
+| 1  | John Doe    | SQL    |
+| 2  | Jane Smith  | C++    |
+| 2  | Jane Smith  | Hadoop |
+| 2  | Jane Smith  | SQL    |
+| 3  | Bob Johnson | Python |
+| 3  | Bob Johnson | Docker |
++----+-------------+--------+
+```
+
+**示例 2：使用 POSEXPLODE 函数**
+`POSEXPLODE` 函数与 `EXPLODE` 类似，但它还会返回数组中元素的位置索引。使用相同的 `employees` 表和插入的数据，我们可以使用 `POSEXPLODE`：
+
+```
+SELECT e.id, e.name, ps.position, ps.skill
+FROM employees e
+LATERAL VIEW POSEXPLODE(e.skills) ps AS position, skill;
++----+-------------+----------+--------+
+| id |    name     | position | skill  |
++----+-------------+----------+--------+
+| 1  | John Doe    | 0        | Java   |
+| 1  | John Doe    | 1        | Python |
+| 1  | John Doe    | 2        | SQL    |
+| 2  | Jane Smith  | 0        | C++    |
+| 2  | Jane Smith  | 1        | Hadoop |
+| 2  | Jane Smith  | 2        | SQL    |
+| 3  | Bob Johnson | 0        | Python |
+| 3  | Bob Johnson | 1        | Docker |
++----+-------------+----------+--------+
+
+```
+
+## 注意事项
+
+* 使用 `LATERAL VIEW` 子句时，请确保已正确指定生成器函数、别名和列标识符。

+# Lakehouse DataGPT 快速导览
+
+Lakehouse DataGPT 是一款前沿的、基于云的对话式数据分析工具，它借助自然语言交互的力量，使数据分析变得像聊天一样轻松。通过利用先进的大型语言模型（LLMs），它让用户能够以对话的方式深入探索数据，以惊人的效率提供精确且深刻的分析结果。
+
+通过 DataGPT 拥抱数据分析的未来，这里人工智能的强大力量与数据源的多样性相结合。无论您的数据存储在强大的 Lakehouse 中，还是在个人文件（如 Excel、CSV 或 PDF）中，DataGPT 都能帮助您释放其分析潜力。这一创新工具打破了数据可访问性的障碍，确保无论数据存储在何处，您都可以利用 DataGPT 的 AI 功能来发现洞察、做出明智决策，并在高级数据分析时代推动成功。
+
+如需了解更多关于 DataGPT 的概念和技术架构，请参阅 [DataGPT 介绍](datagpt_intro.md)。
+
+## 支持的数据源
+
+Lakehouse GPT 能够分析已经存储在 [Lakehouse表](Tables.md)中的数据。这意味着用户可以直接与 Lakehouse GPT 进行对话式数据分析，将 Lakehouse 的应用场景从数据工程和基于 SQL/Python 的分析扩展到交互式、可视化数据分析体验。这为用户提供了更轻松的数据探索方式，使他们能够通过简单的问答交互快速获取数据结果和相应的 SQL 代码。
+
+此外，lakehouse GPT 还支持直接加载 Excel、CSV 和 PDF 等文件，加载的数据将存储在 Lakehouse 中。这样一来，用户无需再为 Lakehouse 的特定概念（如模式、表或 SQL）而烦恼，大大降低了数据分析的入门门槛。
+
+![](.topwrite/assets/image_1742525269996.png)
+
+## 与 DataGPT 展开对话，无缝接收全面的数据分析结果
+
+![](.topwrite/assets/image_1742525285793.png)
+
+我们收到一条通知，指出“**结果需要验证**”。在调查详情时，我们发现查询涉及“**海淀区**”。DataGPT 是一款由大型语言模型（LLM）驱动的数据分析工具，它通过解读“海淀区”并将其与表中地区字段的中文值“海淀”相关联，巧妙地处理了数据的多语言特性。由于表中仅包含中文的地区信息，DataGPT 的推理能力使其能够识别这种对应关系，并无缝对齐数据以得出准确结果。尽管如此，该工具仍提示用户验证结果的准确性。
+
+![](.topwrite/assets/image_1742525306817.png)
+
+此案例清晰地展示了 DataGPT 的强大功能，它借助大型语言模型（LLM）的优势，克服了传统商业智能（BI）工具在数据分析中常常遇到的难题。通过利用大型语言模型（LLM）的强大功能，DataGPT 有效解决了复杂的多语言数据问题，提供了一种超越传统 BI 工具局限性的解决方案，从而提升了整个分析过程的水平。
+
+## 比较分析与多维下钻
+
+基于数据库字段计算的[指标](metrics_answer_build.md)是用于评估绩效、趋势和其他关键数据点的可量化度量标准。这些指标可以通过聚合生成，即将大量数据集汇总成一个或少数几个值，也可以通过应用特定算法或计算的数据自定义代码方法生成。DataGPT 利用大型模型提供了一种自动化的方式，通过大型模型创建这些指标，简化了这一过程，减少了人工干预的需求。这些指标为理解复杂数据提供了一种简洁的方式，有助于做出明智的决策。
+
+基于指标的数据分析包括不同时间段的比较分析和多维下钻。
+
+### 比较分析
+
+比较分析涉及随时间变化和趋势的检查，例如月度环比、年度同比或季度环比，以识别绩效指标中的模式、增长或下降。这种分析对于理解进展和制定战略决策至关重要。
+
+![](.topwrite/assets/image_1742525316900.png)
+
+### 多维下钻
+
+多维下钻是指从多个角度或维度探索数据的过程。这可能涉及按地区、产品线、客户群体或其他相关类别对数据进行分段，以获得更深入的见解。通过下钻，分析师可以揭示影响整体指标的因素，从而实现更具针对性和信息驱动的决策。

+
+### 步骤3：MCP Server 端：启动 MCP Server 镜像
+
+创建 `docker-compose.yml` 文件，拷贝内容到文件中（文件内容详见附录）
+
+在包含该文件的目录下打开终端或命令行，并执行以下命令。
+
+```SQL
+docker compose up -d
+```
+
+预期输出：
+
+```
+bash-3.2$ docker compose up -d
+[+] Running 4/4
+ ✔ Network mcp_docker_clickzetta-net  Created       0.0s 
+   ✔ Container clickzetta-sse           Started       0.2s 
+   ✔ Container clickzetta-http          Started       0.2s 
+   ✔ Container clickzetta-webui         Started       0.2s
+```
+
+校验状态，使用 `docker compose ps --format "table {{.Name}}\t{{.Service}}\t{{.Status}}"` 命令，预期输出如下(忽略 `WARNING` 信息)：
+
+```
+bash-3.2$ docker compose ps --format "table {{.Name}}\t{{.Service}}\t{{.Status}}"
+
+NAME               SERVICE            STATUS
+clickzetta-http    clickzetta-http    Up 5 hours (unhealthy)
+clickzetta-sse     clickzetta-sse     Up 5 hours (unhealthy)
+clickzetta-webui   clickzetta-webui   Up 5 hours (unhealthy)
+```
+
+> 如果需要关闭，请在包含`docker-compose.yml`文件的目录下执行：`docker compose down`
+
+### 步骤4：配置 Claude Desktop
+
+本示例选择的 MCP 客户端工具是 Claude Desktop，主机与 MCP Server 端位于同一台主机
+
+找到并打开 Claude Desktop 配置文件：
+
+**macOS 操作步骤**：
+
+* 打开 Finder
+* 按 `Cmd+Shift+G`
+* 粘贴路径：`~/Library/Application Support/Claude`
+* 双击打开 `claude_desktop_config.json`（用文本编辑器）
+
+**Windows 操作步骤**：
+
+* 按 `Win+R` 打开运行对话框
+* 输入 `%APPDATA%\Claude` 并回车
+* 右键点击 `claude_desktop_config.json`
+* 选择"编辑"或"用记事本打开"
+
+2\. 将以下内容复制到配置文件（替换原有内容或添加到 `mcpServers` 中）：
+
+请输入 MCP Server 的地址：如果服务器与客户端运行在同一台机器上，请填写 `localhost`；否则，请填写服务器的 IP 地址。
+
+```JSON
+{
+  "mcpServers": {
+    "clickzetta-http": {
+      "command": "npx", 
+      "args": [
+        "-y", "mcp-remote",
+        "http://<YOUR_SERVER_IP>:8002/mcp",
+        "--allow-http",
+        "--transport", "http"
+      ]
+    }
+  }
+}
+```
+
+**配置完成**！
+
+^
+
+另外：Claude Desktop 支持通过多种方式连接后端的 MCP Server，以适应不同的部署环境和性能需求。上面的示例介绍了 **HTTP (Streamable**) 协议连接方式，如果想利用 **SSE** 或者 **STDIO** 协议连接，配置也很简单：
+
+**SSE 连接方式（远程服务**）
+
+SSE (Server-Sent Events) 是一种基于 HTTP 的长连接技术，允许服务器向客户端单向推送消息。相比于传统的轮询方式，SSE 能够以更低的延迟实现实时通信。
+
+* **适用场景**：需要从服务器实时接收数据流或更新通知的场景。
+* **Docker Server 配置参考**：此方式对应启动容器中的 `clickzetta-sse` 的服务，该服务在 `8003` 端口上提供服务。
+* **配置示例**：
+  在 Claude Desktop 的 `claude_desktop_config.json` 配置文件中更新如下信息，连接到远程 SSE 端点。
+
+```JSON
+
+{
+  "mcpServers": {
+    "clickzetta-remote-sse": {
+      "command": "npx",
+      "args": [
+        "-y", "mcp-remote",
+        "http://localhost:8003/sse",
+        "--allow-http",
+        "--transport", "sse"
+      ]
+    }
+  }
+}
+```
+
+&#x20;**说明**：
+
+* 请将 `<YOUR_SERVER_IP>` 替换为 MCP Server 实际的 IP 地址或域名。
+* 目标端口为 `8003`，端点路径为 `/sse`。
+* `--transport sse` 参数指明了使用 SSE 通信协议。
+
+***
+
+**STDIO 连接方式（本地进程**）
+
+此方式主要用于本地开发和调试。Claude Desktop 会将 MCP Server 作为一个子进程直接在本地启动，并通过标准输入/输出（STDIO）进行通信。这种方式延迟最低，但不适用于远程连接。
+
+* **适用场景**：本地开发、单机部署。
+* **Docker Server 配置参考**：此方式对应启动容器中的 `clickzetta-stdio` 的服务，该容器镜像会随着 Claude Desktop 的开启和关闭，自动操作容器镜像拉起和停止。
+* **配置示例**：在 Claude Desktop 的 `claude_desktop_config.json` 配置文件中更新如下信息，直接指定启动本地 Server 的命令。
+
+**注意**：
+
+1. 配置文件中 `-v `后的路径中 `USERNAME `**请根据系统的实际路径进行修改**。
+2. 请使用 `docker compose down `关闭创建的相关容器，因为此种方式下，Claude Desktop 会随着自身的开启和关闭，自动操作容器镜像拉起和停止。
+
+```json
+{
+  "mcpServers": {
+    "clickzetta-stdio": {
+      "command": "docker",

+        "--stop-timeout", "60",

+  }
+}
+```
+
+**说明**：
+
+* `command` 和 `args` 直接定义了如何在本地启动 MCP Server。
+* 无需指定 IP 地址和端口。
+* `--transport stdio` 参数指明了使用 STDIO 通信协议。
+
+## 开始使用：
+
+### 部署验证
+
+1\. 打开 Claude Desktop ，在输入框中，发送以下指令：
+
+```Plain
+列出所有 Clickzetta Lakehouse 可用的 MCP工具
+```
+
+ 如果连接成功，您将看到一个包含 50+ 个工具的列表（注意：随着版本更新，工具的具体数量可能会有变化）
+
+2\. **验证 WebUI 界面**
+
+* 在您的浏览器中访问以下地址： `http://localhost:8503, `预期可以展示以下页面：
+
+:-: ![](.topwrite/assets/mcp_web_ui.jpeg =753)
+
+^
+
+如果以上两个步骤都顺利完成，恭喜您，您的应用已成功安装！
+
+### 第二步：配置您的第一个数据源 (Lakehouse)
+
+接下来，让我们配置一个 Lakehouse 连接，以便 Claude 可以访问您的数据。
+
+1. **打开连接管理器**
+
+   访问 WebUI 界面 `http://localhost:8503`，然后在左侧菜单中选择「**连接管理**」。
+
+2. **添加并填写连接信息**
+
+   点击「**添加新连接**」按钮，并根据提示准确填写您的 Lakehouse 连接信息（如主机、端口、凭证等）
+
+:-: ![](.topwrite/assets/mcp_webui_2.jpeg =765)
+
+***
+
+**测试并保存**
+
+1. 填写完毕后，点击「**测试连接**」按钮，确保所有配置信息无误且网络通畅。
+2. 测试通过后，点击「**保存**」完成配置。
+
+### 第三步：开始您的第一个查询
+
+现在一切准备就绪！您可以开始与您的数据进行交互了。尝试在 **Claude Desktop** 中提问：
+
+> "帮我看下有哪些 Lakehouse 实例"
+
+### 高级配置：配置云器产品文档知识库
+
+这个步骤会将云器 Lakehouse 产品知识库表集成进来，构建一个智能问答知识库。配置完成后，您将能够在 MCP Client（如 Claude Desktop）中，通过自然语言提问的方式，快速获得关于 Lakehouse 操作的官方指导和答案
+
+该功能的核心是利用**嵌入服务 (Embedding**) 和**向量搜索 (Vector Search**) 技术，将非结构化的文档转化为可供机器理解和检索的知识库。
+
+#### **第一步：配置嵌入服务**
+
+此步骤的目的是告诉 MCP 系统如何将用户的“问题”也转换成向量，以便在知识库中进行匹配。
+
+1. 在 MCP Server 管理界面，从左侧导航栏进入「**系统配置**」。
+
+2. 在主配置区，选择 「**嵌入服务**」 标签页。
+
+3. 找到并填写 **DashScope 配置**（默认）部分：
+
+   * **API Key**：粘贴您的阿里云百炼平台的 API 密钥。这是调用模型的身份凭证，请妥善保管。
+   * **向量维度 (Vector Dimension**)：输入您选择的嵌入模型所输出的向量维度。**此值必须与知识库文档向量化时使用的维度完全一致**。例如，截图中 `text-embedding-v4` 模型的维度是 `1024`。
+   * **嵌入模型 (Embedding Model**)：选择或填写用于将文本转换为向量的模型名称，例如 `text-embedding-v4`。
+   * **最大文本长度 (Max Text Length**)：设置模型一次可以处理的文本单元（Token）的最大数量。如果问题过长，超出部分将被忽略。![](.topwrite/assets/MCP_config_1.jpeg)
+
+4. 点击 **保存嵌入服务配置** 按钮。
+
+#### **第二步：配置向量搜索**
+
+此步骤的目的是告诉 MCP 系统去哪里、以及如何搜索已经存储好的文档知识库。
+
+1. 在 **系统配置** 页面，切换到 「**向量搜索**」 标签页。
+
+2. 填写 **向量表配置** 部分：
+
+   * **向量表名称 (Vector Table Name**)：准确填写存储了文档向量的完整表名。格式通常为 `数据库名.模式名.表名`，例如 `clickzetta_sample_data.clickzetta_doc.kb_dashscope_clickzetta_elements`。
+   * **嵌入列 (Embedding Column**)：填写该表中用于存储**文本向量**的列名，例如 `embeddings`。
+   * **内容列 (Content Column**)：填写该表中用于存储**原始文本内容**的列名，例如 `text`。当系统找到相关答案时，这里的内容会作为主要参考。
+   * **其他列 (Other Columns**)：可选。填写您希望一并检索出的元数据列，如 `file_directory`, `filename`，这有助于用户追溯信息的原始出处。
+
+3. 配置 **搜索参数**：保持默认即可，如果想进行修改，请参考下面的说明
+
+   * **距离阈值 (Distance Threshold**)：设置一个相似度匹配的严格程度。系统会计算问题向量与文档向量之间的“距离”，只有距离小于此值的文档才会被视为相关。**值越小，代表匹配要求越严格**。通常建议从 `0.80` 开始尝试。
+   * **返回结果数 (Number of Results to Return**)：定义单次查询从数据库中检索出的最相关文档的数量。例如，设置为 `5` 表示每次找出 5 个最相关的文档片段。
+   * **启用重排序 (Enable Reranking**)：勾选此项后，系统会对初步检索出的结果进行二次智能排序，以提高最准确答案出现在最前面的概率。![](.topwrite/assets/MCP_Vector_2.jpeg)
+
+4. 点击 **保存向量搜索配置** 按钮。

+
+**步骤4：验证数据和索引**
+
+```sql
+-- 检查数据插入情况
+SELECT COUNT(*) as total_records FROM ai_knowledge_base;
+
+-- 验证索引创建
+DESC TABLE EXTENDED ai_knowledge_base;
+-- 检查index字段确认所有索引已创建
+
+-- 查看数据概览
+SELECT doc_id, title, category, author_id, view_count 
+FROM ai_knowledge_base 
+ORDER BY doc_id;
+```
+
+### 2.2 基础查询模式
+
+**模式1：精确ID查找（布隆过滤器）**
+
+```sql
+SELECT doc_id, title, author_id, view_count
+FROM ai_knowledge_base
+WHERE author_id = 2001
+ORDER BY view_count DESC;
+
+-- 预期结果：
+-- doc_id: 1004, title: "智能搜索引擎优化策略", view_count: 1680
+-- doc_id: 1001, title: "云器向量数据库技术深度解析", view_count: 1250
+```
+
+**模式2：分类精确匹配（keyword倒排索引）**
+
+```sql
+SELECT doc_id, title, category, view_count
+FROM ai_knowledge_base 
+WHERE category = '技术文档'
+ORDER BY view_count DESC;
+
+-- 预期结果：返回3条技术文档记录
+```
+
+**模式3：内容搜索（chinese倒排索引）**
+
+```sql
+SELECT doc_id, title, view_count
+FROM ai_knowledge_base
+WHERE content LIKE '%平台%'
+ORDER BY view_count DESC;
+
+-- 预期结果：返回包含"平台"的相关文档
+```
+
+**模式4：语义搜索（向量索引）**
+
+```sql
+-- AI语义相似度搜索
+WITH query_vector AS (
+  SELECT ARRAY[0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1] || ARRAY_REPEAT(0.1, 760)::ARRAY<FLOAT> as qv
+)
+SELECT 
+    a.doc_id, 
+    a.title, 
+    COSINE_DISTANCE(a.embedding, q.qv) as similarity_score
+FROM ai_knowledge_base a, query_vector q
+WHERE a.embedding IS NOT NULL
+ORDER BY similarity_score ASC
+LIMIT 3;
+
+-- 预期结果：按语义相似度排序，AI相关文档排名最前
+```
+
+***
+
+## 3. 索引选择决策框架
+
+### 3.1 决策树
+
+```
+查询需求分析
+├── 需要精确ID查找？
+│   └── YES → 布隆过滤器索引
+│       ├── 单表查询 → 单布隆过滤器
+│       └── 关联查询 → 多布隆过滤器
+├── 需要文本内容搜索？
+│   ├── 精确分类匹配 → keyword分词 + 倒排索引
+│   ├── 中文内容搜索 → chinese分词 + 倒排索引
+│   ├── 多语言处理 → unicode分词 + 倒排索引
+│   └── 复合文本查询 → 多倒排索引组合
+├── 需要语义相似搜索？
+│   └── YES → 向量索引 + 其他索引过滤
+└── 复杂业务查询？
+    └── 多索引融合策略
+```
+
+### 3.2 分词器选择指南
+
+**实际分词效果对比**：
+
+```sql
+-- 验证不同分词器效果
+SELECT 
+    'chinese' as analyzer,
+    TOKENIZE('云器Lakehouse数据湖仓平台', map('analyzer', 'chinese')) as tokens
+UNION ALL
+SELECT 
+    'unicode' as analyzer,
+    TOKENIZE('云器Lakehouse数据湖仓平台', map('analyzer', 'unicode')) as tokens  
+UNION ALL
+SELECT 
+    'keyword' as analyzer,
+    TOKENIZE('云器Lakehouse数据湖仓平台', map('analyzer', 'keyword')) as tokens;
+```
+
+**实际分词结果**：
+
+| 分词器       | 分词结果                                            | 最佳应用场景   |
+| --------- | ----------------------------------------------- | -------- |
+| `chinese` | `["云器", "lakehouse", "数据", "湖仓", "平台"]`         | 中文内容智能搜索 |
+| `unicode` | `["云", "器", "lakehouse", "数据", "湖", "仓", "平台"]` | 多语言标题搜索  |
+| `keyword` | `["云器Lakehouse数据湖仓平台"]`                         | 分类标签精确匹配 |
+
+**选择原则**：
+
+* **category、status字段** → keyword（精确匹配，零开销）
+* **中文content、description** → chinese（智能分词，语义理解）
+* **混合语言title、name** → unicode（通用支持，细粒度搜索）
+
+***
+
+## 4. 高级查询模式与优化
+
+### 4.1 多索引融合查询
+
+**场景：AI智能检索系统**
+
+```sql
+-- 向量语义搜索 + 倒排索引过滤 + 布隆过滤器
+WITH query_vector AS (
+  SELECT ARRAY[0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1] || ARRAY_REPEAT(0.1, 760)::ARRAY<FLOAT> as qv
+)
+SELECT 
+    a.doc_id, 
+    a.title, 
+    a.category,
+    a.view_count,
+    COSINE_DISTANCE(a.embedding, q.qv) as similarity_score
+FROM ai_knowledge_base a, query_vector q
+WHERE a.category IN ('技术文档', '最佳实践', '架构设计')  -- 倒排索引分类过滤
+AND a.embedding IS NOT NULL  
+AND a.view_count > 500  -- 质量筛选
+ORDER BY similarity_score ASC  -- 语义相似度优先
+LIMIT 5;
+
+-- 预期结果：返回语义最相关的高质量文档
+```
+
+### 4.2 演示数据详细说明
+
+**数据集概览**：8篇技术文档，涵盖5个分类，5位作者，所有文档都包含768维embedding向量
+
+| 分类       | 文档数 | 代表性文档                 | 平均浏览量 |
+| -------- | --- | --------------------- | ----- |
+| **技术文档** | 3篇  | 云器向量数据库、智能搜索引擎、深度学习部署 | 1,273 |
+| **架构设计** | 2篇  | AI大模型训练平台、流式计算引擎      | 1,090 |
+| **最佳实践** | 1篇  | 实时推荐系统                | 2,100 |
+| **数据治理** | 1篇  | 企业数据治理与安全合规           | 1,450 |
+| **性能调优** | 1篇  | 数据湖仓一体化性能调优           | 3,200 |
+
+**向量设计说明**：
+
+* **AI相关文档**(1001,1002,1003,1006): 前几维度数值较高，形成相似向量模式
+* **搜索引擎文档**(1004): 中间维度较高，向量模式差异化
+* **性能调优文档**(1005): 后段维度较高，便于验证向量相似度搜索效果
+
+这种设计确保了向量搜索的可验证性：AI相关主题的文档会聚集在一起，而不同主题的文档有明显的向量差异。

+
+## 5. 索引管理与配置
+
+### 5.1 索引管理操作
+
+**创建索引最佳实践**：
+
+< date '2024-02-01';
+```
+
+**索引状态检查**：
+
+```sql
+-- 查看完整索引信息
+DESC TABLE EXTENDED your_table_name;
+
+-- 查看表创建语句
+SHOW CREATE TABLE your_table_name;
+
+-- 检查索引列表
+SHOW INDEX FROM your_table_name;
+```
+
+### 5.2 向量索引参数配置
+
+**向量索引参数详解**：
+
+| 参数                    | 推荐值        | 影响因素     | 使用建议              |
+| --------------------- | ---------- | -------- | ----------------- |
+| `m`                   | 16-64      | 精度vs内存   | 精度要求高用32+，性能优先用16 |
+| `ef.construction`     | 128-512    | 构建质量vs时间 | 生产环境推荐256+        |
+| `scalar.type`         | f32/f16    | 精度vs存储   | 一般用f32，大规模用f16    |
+| `distance.function`   | cosine/l2  | 语义vs空间距离 | 文本用cosine，图像用l2   |
+| `compress.codec`      | zstd/none  | 存储vs计算   | 存储敏感用zstd         |
+| `reuse.vector.column` | true/false | 存储优化     | 大规模部署推荐true       |
+
+**高精度 vs 高性能配置对比**：
+
+```sql
+-- 高精度场景配置（适用于对准确性要求高的AI应用）
+CREATE VECTOR INDEX high_precision_idx ON TABLE vectors(embedding)
+PROPERTIES(
+    'scalar.type' = 'f32',
+    'distance.function' = 'cosine_distance',
+    'm' = '32',                    -- 增加邻居数提升精度
+    'ef.construction' = '256',     -- 增加候选集提升质量
+    'compress.codec' = 'zstd'      -- 启用压缩节省空间
+);
+
+-- 高性能场景配置（适用于对速度要求高的实时应用）
+CREATE VECTOR INDEX high_speed_idx ON TABLE vectors(embedding)
+PROPERTIES(
+    'scalar.type' = 'f16',         -- 半精度减少内存占用
+    'distance.function' = 'l2_distance',
+    'm' = '16',                    -- 减少邻居数提升速度
+    'ef.construction' = '128',
+    'reuse.vector.column' = 'true' -- 复用列数据节省存储
+);
+```
+
+***
+
+## 6. 常见问题与故障排除
+
+### 6.1 索引创建问题
+
+**问题1：向量索引创建失败**
+
+```
+错误信息：向量维度不匹配
+解决方案：检查VECTOR(FLOAT, n)定义与实际数据维度是否一致
+```
+
+**问题2：布隆过滤器不生效**
+
+```
+原因：布隆过滤器仅对新数据生效，不支持BUILD INDEX
+解决方案：对于存量数据，考虑使用倒排索引替代
+```
+
+**问题3：中文分词效果不佳**
+
+```
+原因：使用了错误的分词器
+解决方案：中文内容使用'analyzer'='chinese'，精确匹配使用'keyword'
+
+-- 验证分词效果
+SELECT TOKENIZE('测试文本', map('analyzer', 'chinese')) as chinese_tokens,
+       TOKENIZE('测试文本', map('analyzer', 'keyword')) as keyword_tokens;
+```
+
+**问题4：向量函数不可用**
+
+```
+错误信息：COSINE_DISTANCE函数未找到
+解决方案：确认版本支持，验证函数可用性
+
+-- 验证向量函数
+SELECT COSINE_DISTANCE(
+    ARRAY[0.1, 0.2, 0.3]::ARRAY<FLOAT>
+
+### 5.2 查询优化问题
+
+**诊断流程**：
+
+1. 使用EXPLAIN分析查询计划
+2. 检查索引是否被正确使用
+3. 分析数据分布和倾斜情况
+4. 评估索引选择性
+
+**优化策略**：
+
+```sql
+-- 避免的反模式
+WHERE UPPER(category) = 'TECH'           -- 函数调用破坏索引
+WHERE CAST(id AS STRING) = '123'         -- 类型转换影响性能
+WHERE content LIKE '%keyword%keyword%'   -- 复杂模式匹配
+
+-- 推荐的写法
+WHERE category = 'tech'                  -- 直接匹配，预处理数据统一格式
+WHERE id = 123                          -- 类型匹配
+WHERE content LIKE '%keyword%'          -- 简单模式
+```
+
+### 5.3 故障排除检查清单

+# MATERIALIZED VIEW（物化视图）
+
+物化视图是一种特殊的数据库对象，它可以定期缓存查询结果以提高性能和效率。由于物化视图中的数据是预先计算好的，因此查询物化视图通常比直接查询基表更快。当查询频繁运行或足够复杂时，这种性能差异可能会非常明显。因此，物化视图可以加速昂贵的聚合、投影和选择操作，尤其是那些频繁运行在大型数据集上的操作。
+
+## 物化视图
+
+* 物化视图可以提高重复使用相同子查询结果的查询的性能，并支持查询改写。
+* 当物化视图的基础表发生插入、覆写、更新、删除等操作时，物化视图会自动失效，无法用于查询改写。
+
+## 何时创建物化视图
+
+物化视图特别适用于以下情况：
+
+* 查询结果包含与基础表相比少量的行和/或列。
+* 查询结果需要大量处理，包括半结构化数据分析、长时间计算的聚合等。
+* 物化视图的基础表不经常变化。
+
+## 云器Lakehouse物化视图特点
+
+* 物化视图可以提高重复使用相同子查询结果的查询的性能。
+* 物化视图支持定时刷新功能。通过SQL语法创建定时刷新任务，与在应用程序级别手动维护物化视图相比，这种方式更有效且更不容易出错。
+
+## 物化视图与普通视图的选择
+
+通常，当决定创建物化视图还是普通视图时，可以使用以下标准：
+
+* 如果视图的查询结果不经常变化、结果使用频繁且查询消耗大量资源，则创建物化视图。
+* 如果视图的结果经常变化、结果不经常使用或查询不消耗太多资源，则创建普通视图。
+
+## 物化视图与表、普通视图和缓存结果的比较
+
+物化视图与表在某些方面相似，与普通（非物化）视图在其他方面相似。此外，物化视图与缓存结果有一些相似之处，特别是两者都允许存储查询结果以供将来重用。
+
+
+## 物化视图管理
+
+云器Lakehouse提供了以下DDL命令来创建和维护物化视图：
+* [创建物化视图](CREATEMATERIALIZEDVIEW.md)：创建物化视图需要指定基表、查询语句以及其他相关参数。创建成功后，物化视图将存储在数据库中，以便后续查询使用。
+* [删除物化视图](DROPMATERIALIZEDVIEW.md)：当物化视图不再需要时，可以通过执行删除操作来释放相关资源。
+* [刷新物化视图](REFRESH.md)：当物化视图中的数据需要更新时，可以通过执行刷新操作来更新物化视图的数据。
+
+更多操作请参考[物化视图命令详情](<materialized_ddl.md>)。
+
+## 应用场景
+
+以下使用场景重点介绍了物化视图的价值。如果您的应用场景符合以下条件，那么物化视图可以提高查询性能：
+
+* **预汇总数据**：如果您需要对大量数据进行汇总分析，物化视图可以利用定时任务进行预先汇总，从而提高查询性能。
+* **预过滤数据**：如果您的查询只需要读取表的特定部分，物化视图可以预先过滤数据，从而减少查询时的数据量。
+* **预联接数据**：如果您的查询需要联接多个表，尤其是大型表和小型表之间的联接，物化视图可以预先进行联接操作，从而提高查询性能。
+
+## Materialized View和Dynamic Table区别
+
+从Lakehouse的实现机制上来看，动态表是基于传统的物化视图演进而来，虽然两者有一些共性，但在定位上存在很大区别。
+
+**物化视图：性能优化利器** 物化视图是一种预计算并存储查询结果的特殊视图，它能够显著提升查询效率。与传统视图不同，物化视图将计算结果保存在类似表的结构中，使得后续相似查询能够被优化器自动识别并直接使用预存结果，从而减少重复计算，加快查询速度。
+
+**动态表：数据加工的高效工具** 动态表专注于数据加工，虽然也能提升查询性能，但它并不依赖于查询优化器的自动重写。物化视图只有保持数据是最新的才能用于查询改写；而动态表面向加工场景，其数据可能并不是最新的。
+
+**传统物化视图在某些产品中具有以下限制，目前Lakehouse没有这些限制**：
+
+1. 只能使用单个基表。物化视图不能基于复杂查询（即具有联接或嵌套视图的查询）。
+
+2. 物化视图不一定是增量刷新，每个系统的实现不同。少量系统为了节省计算资源、加快加工速度，在部分算子中实现了增量计算。
+
+**动态表的先进特性**：
+
+1. **增量识别与优化**：支持大数据环境下的文件粒度增量识别，实现实时增量读取和计算优化，以及写入优化。
+2. **智能决策**：通过基于成本的优化器(Cost-Based Optimizer)智能选择全量、增量或部分增量计算，以适应不同查询需求。
+3. **实时任务运维**：提供数据版本管理、回退和重跑等机制，为实时任务的运维提供全面支持。
+
+**数据时效性考量**：
+
+* 物化视图要求数据的即时更新，以确保查询改写的准确性。在基表数据变更时，Lakehouse采用定时刷新机制，确保物化视图的数据始终保持最新。
+* 动态表则更注重数据加工的灵活性，根据业务定义来调整数据的滞后性，而不强制要求数据必须实时更新。
+
+## 查询改写功能
+
+目前Lakehouse的查询改写功能处于Preview阶段。如果您需要使用该功能，在提交SQL查询时请使用以下配置：
+`set cz.optimizer.enable.mv.rewrite=true;`
+
+具体案例
+
+```SQL
+
+create table product_sales(sale_id int, product_name string, sale_date string, quantity_sold int);
+INSERT INTO product_sales (sale_id, product_name, sale_date, quantity_sold)
+VALUES
+(1, 'Widget', '2024-05-01', 10),
+(2, 'Widget', '2024-05-02', 20),
+(3, 'Gadget', '2024-05-01', 15),
+(4, 'Widget', '2024-05-03', 5);
+CREATE MATERIALIZED VIEW product_sales_filter AS
+SELECT    sale_id,
+          product_name,
+          sale_date
+FROM      product_sales
+WHERE     sale_id < 3;
+
+set cz.optimizer.enable.mv.rewrite=true;
+SELECT    sale_id,

+          sale_date
+FROM      product_sales

+          product_name
+FROM      product_sales

+在 Claude Desktop 的 Settings 中找到 **Local MCP servers** 配置入口，点击 **Edit Config** 打开 `claude_desktop_config.json` 文件。
+
+配置文件路径通常为：
+
+* **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
+* **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
+
+#### 步骤 2：配置MCP
+
+* 在产品内，点击左下角个人信息「Lakehouse MCP」
+* 在下图页面中生成个人的token，并配置该token对应的连接环境信息。
+
+注意：使用该token时具备此用户身份的全部权限。因此请妥善保管token，避免泄露造成安全风险。
+
+
+![](/.topwrite/assets/image_1766485071003.png)
+
+^
+
+* 生成token后，在右侧的连接配置可看到mcp的配置json，复制后粘贴至`claude_desktop_config.json文件中。`
+
+```SQL
+{  "clickzetta-http": {   
+ "command": "npx",   
+ "args":  [     
+ "-y", "mcp-remote",   
+   "https://cn-shanghai-alicloud-mcp.clickzetta.com/mcp",   
+   "--allow-http",  
+    "--transport", "http",    
+  "--header", "x-Lakehouse-Token: Bearer <your_token>"    ]  }}
+```
+
+### 2.3 Cherry Studio 配置
+
+如果使用 Cherry Studio：
+
+1. 打开 **设置** → **MCP** → 点击 **添加服务器**
+
+2. 配置如下：
+
+   1. **名称**：`Clickzetta MCP`
+   2. **类型**：`可流式传输的 HTTP (streamableHttp)`
+   3. **URL**：`https://cn-shanghai-alicloud-mcp.clickzetta.com/mcp`
+   4. **请求头**（每行一个）：
+
+```Plain
+ x-Lakehouse-Token=Bearer <your_pat>
+x-Lakehouse-Region= cn-shanghai-alicloud
+```
+
+### 2.4 验证配置
+
+重启 Claude Desktop 或 Cherry Studio，在对话框中输入：
+
+```Plain
+列出当前工作空间中的所有文件夹
+```
+
+如果返回文件夹列表，说明配置成功！

+### Q\&A
+
+#### 1. Claude Desktop 提示找不到 npx / Failed to spawn process
+
+Q1：Claude Desktop 配好 MCP Server 后连不上，日志里出现 `Failed to spawn process: No such file or directory`
+
+**A**：这通常表示 Claude Desktop 在启动本地 MCP 连接时，需要执行你配置里的 `command`（常见是 `npx`），但在 Claude Desktop 的运行环境里找不到该可执行文件（或无法在 PATH 中定位）。
+在本文的 HTTP(streamable) 示例中，`command` 默认是 `npx`，而 `mcp-remote` 依赖 Node.js/npm 环境。
+
+**修复方式为**：
+
+**在macOS系统中**：
+
+**1）确认本机是否安装了 Node.js（含 npx**）
+打开 Terminal 执行：
+
+* `node -v`
+* `npx -v`
+* `which npx`
+
+若 `npx -v` 报错或 `which npx` 无输出，说明 Node.js/npm 未安装或不可用。
+
+**2）安装 Node.js（推荐让 GUI 应用也能找到 npx**）
+
+* \*\*推荐方式：\*\*使用 Homebrew 安装 Node.js（npx 路径更稳定、GUI 应用更容易识别）。
+
+  * 若提示 `brew: command not found`，先安装 Homebrew，再 `brew install node`。
+
+* \*\*替代方式：\*\*使用 Node.js 官方 macOS Installer 安装（同样可用）。
+
+**3）处理 GUI App 的 PATH 和 Terminal 不一致**
+即使 Terminal 里 `npx` 正常，Claude Desktop 仍可能找不到。此时建议：
+
+* 在 `claude_desktop_config.json` 里把 `"command": "npx"` 改为 **npx 的绝对路径**（以 `which npx` 输出为准），例如：
+
+  * Apple Silicon 常见：`/opt/homebrew/bin/npx`
+  * Intel 常见：`/usr/local/bin/npx`
+
+**4）重启 Claude Desktop 再验证**
+
+****
+
+**在windows系统中**：
+
+**1）确认 Node.js 是否安装并已加入 PATH**
+打开 PowerShell 或 CMD，执行：
+
+* `node -v`
+* `npx -v`
+* `where npx`
+
+若找不到，安装 Node.js（建议 LTS），安装时勾选 **Add to PATH**（或安装后手动把 Node 安装目录加入系统 PATH）。
+
+**2）如果 Claude Desktop 仍找不到 npx：用绝对路径指定命令**
+在 `claude_desktop_config.json` 中把 `"command": "npx"` 改为 `npx.cmd` 的绝对路径（以 `where npx` 输出为准），例如常见路径类似：
+
+* `C:\Program Files\nodejs\npx.cmd`
+
+**3）重启 Claude Desktop 再验证**

+# 功能
+
+
+`MERGE INTO` 语句用于根据源表或子查询中的值更新目标表中的记录。当源表包含目标表中的新行（待插入）、修改行（待更新）和删除行（待删除）时，可以使用此功能来同步目标表的数据。
+
+
+# 语法
+
+
+```SQL
+MERGE INTO target_table 
+   USING source_table
+   ON merge_condition
+   { WHEN MATCHED [ AND matched_condition ] THEN matched_action |
+    WHEN  MATCHED [ AND matched_condition ] THEN matched_action |
+    --当WHEN MATCHED语句和WHEN NOT MATCHED 语句同时存在时，MERGE INTO语句中只能存在一个WHEN NOT MATCHED
+    WHEN NOT MATCHED [ AND not_matched_by_source_condition ] THEN not_matched_by_source_action } 
+-- 参数解释
+matched_action ::=
+    UPDATE SET <column_name> = <expr> [ , <column_name2> = <expr2> ... ] 
+    | DELETE 
+not_matched_action ::=
+    INSERT [ ( <column_name> [ , ... ] ) ] VALUES ( <expr> [ , ... ] )
+```
+
+
+## 参数说明
+
+
+- `target_table`：指定目标表，可以使用别名。
+- `source_table`：指定要与目标表进行比较的表或子查询，可以使用别名。
+- `merge_condition`：定义如何将源表中的行与目标表中的行进行匹配，返回布尔类型的表达式。
+- `WHEN MATCHED [ AND matched_condition ]`：当源行根据 `merge_condition` 和可选的 `matched_condition` 与目标表行匹配时，执行 `WHEN MATCHED` 子句。
+  - 如果对于匹配 `merge_condition` 的源行和目标行对，没有任何 `WHEN MATCHED` 条件的计算结果为 true，则目标行保持不变。
+  - 如果存在多个 `WHEN MATCHED` 子句，则会按照它们的指定顺序对其进行求值。每个 `WHEN MATCHED` 子句都必须具有一个 `matched_condition`。
+- `WHEN NOT MATCHED [ AND not_matched_condition ]`：当源行根据 `merge_condition` 和可选的 `not_matched_condition` 与目标表中的任何行都不匹配时，执行 `WHEN NOT MATCHED` 子句。
+  - 只能存在一个`WHEN NOT MATCHED`语句
+- `matched_action`：
+  - `DELETE`：删除匹配的目标表行。
+  - `UPDATE`：更新匹配的目标表行。使用 `UPDATE SET column1 = source.column1 [, column2 = source.column2 ...]`。
+- `not_matched_action`：
+  - `INSERT`：使用源数据集中的相应列插入目标表，支持指定字段插入。对于未指定的目标列，则插入为 `NULL`。
+
+
+## 注意事项
+
+
+当执行 `MERGE INTO` 语句可能产生不确定结果时，系统会报错。产生这种情况的原因有：
+
+
+1. 如果 `ON` 子句使得源表中的多于 1 行与目标表中的行匹配，SQL 标准要求引发错误。
+2. 如果 `ON` 子句使得源表中的多于 1 行与目标表中的行匹配，同时在 `AND case_predicate` 条件过滤后仍有多条记录。
+3. 当WHEN MATCHED语句和WHEN NOT MATCHED 语句同时存在时，MERGE INTO语句中只能存在一个WHEN NOT MATCHED
+4. 当存在多个 WHEN MATCHED 子句时，UPDATE 语句必须在 DELETE 语句之前。
+
+
+
+
+确定性结果的情况：
+
+
+1. 如果 `ON` 子句使得源表中的 1 行与目标表中的行匹配。
+2. 如果 `ON` 子句使得源表中的多于 1 行与目标表中的行匹配，同时在 `AND case_predicate` 条件过滤后只有一条记录。
+
+
+
+

+**说明**：源表中 id 为 1 和 2 的记录在目标表中找到匹配项，这两条记录被删除。id 为 3 的 Charlie 记录因为在源表中没有匹配项，保持不变。
+
+
+
+
+### 案例2：基于时间戳的条件更新
+
+
+**场景**：只在源表数据更新时间比目标表更新时间更新时，才更新目标表的值
+
+
+**建表语句**
+
+
+```sql
+-- 目标表：产品信息
+CREATE TABLE products_target (
+  id INT,
+  name STRING,
+  col1 STRING,
+  updated_at STRING
+);
+
+
+-- 源表：新的产品数据
+CREATE TABLE products_source (
+  id INT,
+  name STRING,
+  col1 STRING,
+  updated_at STRING
+);
+```
+
+
+**初始目标表数据：**
+```sql
+INSERT INTO products_target VALUES 
+(1, 'Product A', 'value_old', '2024-01-01'),
+(2, 'Product B', 'value_old', '2024-01-02'),
+(3, 'Product C', 'value_old', '2024-01-03');
+```
+
+```
++----+------------+-----------+------------+
+| id | name       | col1      | updated_at |
++----+------------+-----------+------------+
+| 1  | Product A  | value_old | 2024-01-01 |
++----+------------+-----------+------------+
+| 2  | Product B  | value_old | 2024-01-02 |
++----+------------+-----------+------------+
+| 3  | Product C  | value_old | 2024-01-03 |
++----+------------+-----------+------------+
+```
+
+
+**初始源表数据：**
+```sql
+INSERT INTO products_source VALUES 
+(1, 'Product A', 'value_new', '2024-01-10'),
+(2, 'Product B', 'value_old', '2024-01-01'),
+(4, 'Product D', 'value_new', '2024-01-04');
+```
+
+```
++----+------------+-----------+------------+
+| id | name       | col1      | updated_at |

++----+------------+-----------+------------+
+| 2  | Product B  | value_old | 2024-01-01 |
++----+------------+-----------+------------+
+| 4  | Product D  | value_new | 2024-01-04 |
++----+------------+-----------+------------+
+```
+
+
+**MERGE SQL**
+
+
+```sql
+MERGE INTO products_target t USING products_source s
+ON t.id = s.id
+WHEN MATCHED AND t.updated_at < s.updated_at THEN UPDATE SET t.col1 = s.col1;
+```
+
+**执行结果**
+
+
+```
++----+------------+-----------+------------+
+| id | name       | col1      | updated_at |
++----+------------+-----------+------------+
+| 1  | Product A  | value_new | 2024-01-01 |
++----+------------+-----------+------------+
+| 2  | Product B  | value_old | 2024-01-02 |
++----+------------+-----------+------------+
+| 3  | Product C  | value_old | 2024-01-03 |
++----+------------+-----------+------------+
+```
+
+
+**说明**：
+- **Product A (id=1)**：源表的更新时间 `2024-01-10` > 目标表的 `2024-01-01`，条件满足，col1 被更新为 `value_new`
+- **Product B (id=2)**：源表的更新时间 `2024-01-01` ≤ 目标表的 `2024-01-02`，条件不满足，保持不变
+- **Product C (id=3)**：源表中没有对应记录（id=3），不进行任何操作，保持不变
+- **Product D (id=4)**：源表新增，由于不存在 ON 条件的 WHEN NOT MATCHED 子句，不插入
+
+
+
+
+### 案例3：删除标记与条件更新的组合
+
+
+**场景**：对用户数据进行操作，标记为删除的用户直接删除，其他匹配的用户更新其状态信息
+
+
+**建表语句**
+
+
+```sql
+-- 目标表：用户信息

+| 4  | User D | true                | 2024-01-04 | inactive|
++----+--------+---------------------+------------+---------+
+```
+
+
+**说明**：
+- **User A (id=1)**：`marked_for_deletion=false`，满足第一个 WHEN MATCHED 条件，更新 `updated_at` 和 `value`
+- **User B (id=2)**：`marked_for_deletion=true`，满足第二个 WHEN MATCHED 条件，被删除
+- **User C (id=3)**：`marked_for_deletion=false`，满足第一个 WHEN MATCHED 条件，更新 `updated_at` 和 `value`
+- **User D (id=4)**：源表中没有对应记录，保持不变
+- **User E (id=5)**：源表新增，但没有 WHEN NOT MATCHED 子句，不插入
+
+
+---
+
+
+### 案例4：插入与更新的完整同步
+
+
+**场景**：完整的数据同步操作，既要更新匹配的记录，也要插入新的记录
+
+
+**建表语句**
+
+
+```sql

+# 账户管理指南
+
+本指南将详细介绍如何管理您的云器 Lakehouse 账户，包括登录管理中心、管理账户信息和用户等操作。
+
+## 1. 基本概念
+
+### 账户名称
+
+在云器 Lakehouse 中，每个账户都有一个唯一的标识，用于在全球范围内区分不同的账户。账户名称由一个8位的随机字符串组成，在您完成注册后，系统会自动生成。账户名称也决定了您的登录地址和部分访问配置。
+
+账户名称是您在云器 Lakehouse 内的唯一识别名称，一经生成后不可变更。您可以通过注册完成后的提示或管理中心的首页找到您的账户名称。
+
+:-: ![](.topwrite/assets/image_1739329828430.png =780)
+
+^
+
+:-: ![](.topwrite/assets/image_1739329908616.png =783)
+
+### 登录地址
+
+在云器产品中，每个账户拥有其独立的登录地址。登录地址的为<你的账户名称>.accounts.clickzetta.com。
+
+:-: ![](.topwrite/assets/image_1739329970639.png =799)
+
+### 服务实例名称
+
+云器 Lakehouse 是一个多云的大数据平台，支持在多个云厂商的不同 region 下创建服务实例。每个服务实例的开通都相当于在该region内生成一个唯一标识并在基础设施资源中划分出一片逻辑区域，用于为您提供Lakehouse的相关服务。服务实例名称（instance_name）即为服务实例的唯一标识，在您开通服务实例时自动生成，由一段8位的随机字符串组成。您可在服务实例的URL，或服务实例首页右侧找到您的服务实例名称。
+
+:-: ![](.topwrite/assets/image_1740540520113.png =807)
+
+### 账户注册手机
+
+账户注册手机是您在创建账户并添加第一个用户时填写的手机号码。初始账户手机号与您在账户下的第一个用户的手机号码相同。账户管理员可以在管理中心中更改注册手机号。请妥善保管您的注册手机号，因为在云器产品中，每个注册手机号只能对应一个账户，这是找回账户的唯一凭证。
+
+:-: ![](.topwrite/assets/image_1739330026163.png =806)
+
+^
+^
+
+## 2. 账户名称与标识
+
+### 为什么需要账户名称
+
+* **全局唯一性**：账户名称可帮助您在云器 Lakehouse 的全局服务网络中，唯一区分您的账户。
+* **安全控制**：在启用账户安全策略和第三方应用集成时，账户名称是必需的信息，用于访问或交互。
+
+### 账户名称的常用场景
+
+Lakehouse的账户名称主要用于以下场景：
+
+**1. 登录Lakehouse Web 界面**
+
+当您要登录 Lakehouse 的管理中心或Web界面时，需要在浏览器中输入正确的账户 URL（<您的账户名称>.accounts.clickzetta.com）。
+
+^
+
+### 为什么需要服务实例名称
+
+* **全局唯一性**：实例名称可帮助您在云器 Lakehouse 的全局服务网络中，唯一区分您的服务实例。服务名称包含了region信息，可以直接与region内Lakehouse服务进行交互，简化了交互时的访问链路。
+* **安全控制**：在启用网络安全策略和使用第三方客户端访问Lakehouse时，服务名称是必需的信息，用于访问或交互。
+* **资源链接**：在进行数据共享等功能时，需要明确指定目标或源账户的服务实例名称。
+
+### 服务实例名称的常用场景
+
+**1. Lakehouse CLI / 其他客户端 / 驱动**
+
+当使用 CLI、JDBC 驱动、Python/R/Java 等客户端或第三方工具（如 BI 工具）连接 Lakehouse 时，需要在连接配置中指定服务实例名称。
+
+**2. 第三方应用与服务集成**
+
+当外部应用（如数据分析平台、ETL 工具、云存储服务）与 Lakehouse 交互时，需提供服务实例名称来确定目标 Lakehouse 服务。
+
+**3. 数据共享操作**
+
+在 Lakehouse 的“数据共享”功能中，需要使用服务实例名称来定义操作范围。
+
+^
+
+## Lakehouse账户URL与登录
+
+### 登录地址格式
+
+在云器 Lakehouse 中，每个账户拥有其独立的登录地址（URL）。一般格式如下：
+
+[https://<您的账户名称>.accounts.clickzetta.com](https://<您的账户名称>.accounts.clickzetta.com)
+
+示例：
+
+如果您的账户名称为41nprq1k，则登录地址为：
+
+41nprq1k.accounts.clickzetta.com
+
+### 使用账户名称登录
+
+您可以直接在浏览器中输入 `https://<您的账户名称>.accounts.clickzetta.com`，进入登录页面。在登录页面中，您需要输入或选择正确的账户名称，以及用户名和密码。您的账户下可能存在一个或多个用户，您可以在上述页面中登录任一用户。您也可以通过输入用户的手机号码找回用户名或重置用户密码。当多个用户共用一个手机号码时，您可以通过该手机号码找回所有关联的用户名，以便选择所需登录的用户。
+
+### 登录流程与找回方式
+
+1\. 访问 `https://<账户标识>.accounts.clickzetta.com` 或统一入口 `https://accounts.clickzetta.com`。
+
+2\. 在登录页面，输入或选择正确的账户名称，并输入您的 **用户名**、**密码**。
+
+3\. 如果忘记用户名或密码，可以在完成账户名称输入后，通过用户的手机号找回。
+
+当多个用户共用一个手机号码时，可通过该号码找回关联的所有用户名，并选择所需的用户登录。
+
+4\. 如果忘记账户名称，可以在登录页面通过账户的注册手机号找回，一个手机号仅对应一个注册账户。
+
+^
+
+## 在SQL / 配置文件 / 第三方工具中使用账户标识
+
+为了在各种环境下准确指定目标 Lakehouse 账户，您需要根据具体场景选择合适的账户标识格式：
+
+### 在SQL语句中使用
+
+当您在 Lakehouse SQL 中需要引用其他账户（例如进行数据共享）时，使用：服务实例名称（instance_name）。
+
+例如：
+
+`--为数据共享指定分享实例`
+
+`ALTER SHARE share_demo ADD INSTANCE <instance_name>;`
+
+### 在配置文件或第三方工具中使用
+
+* **SQL客户端、驱动或库配置**
+
+在某些SQL客户端（如DBeaver）JDBC驱动或Python/Java库的配置文件中，需要配置链接参数，例如配置DBeaver驱动时：
+
+:-: ![](.topwrite/assets/image_1740549280083.png =361)
+
+JDBC 连接字符串内，需要使用服务实例名称（instance_name），如：
+
+`jdbc:clickzetta://<your_instance_name>.ap-southeast-1-alicloud.api.clickzetta.com/demo_workspace?username=demo_user&password=DemoPassword&schema=public&virtualCluster=DEFAULT`
+
+再例如配置Python SDK时，需要使用服务实例名称（instance\_name）：
+
+`from clickzetta import connect`
+
+`# 建立连接`
+
+`conn = connect(username='username',`
+
+`               password='password',`
+
+`               service='<region\_id>.api.clickzetta.com',`
+
+`               instance='your_instance_name',`
+
+`               workspace='quickstart_ws',`
+
+`               schema='public',`
+
+`               vcluster='default')`
+
+^
+^
+
+## 维护账户信息
+
+### 查看账户注册手机
+
+当您使用具备账户管理员角色的用户登录云器后，可以在管理中心对您的账户进行管理。在“账户主页”页面，您可以查看账户的基本信息以及账户的登录URL。您还可以点击注册手机号右侧的“修改”按钮，更改账户注册的手机号码。
+请注意，您可在“账户中心”页面分别看到“账户信息”中的注册手机——这意味着该账户绑定的手机号码，可通过该手机号找回账户名称；以及“用户信息”中的“注册手机”——这意味着当前登录用户的手机号码，仅与当前登录用户身份绑定，可用于当前用户登录时的 MFA 验证、找回用户名、找回密码等操作。请注意区分。
+
+![](.topwrite/assets/image_1740550879753.png)
+
+### 修改账户注册手机
+
+如果需要修改账户注册手机，需要具备账户管理员（account_admin）身份的用户登录。在进入“账户中心”后，点击“账户信息”栏“注册手机”旁的修改按钮，在验证完旧手机号码后，可以录入并修改为新的手机号。
+

+
+:-: ![](.topwrite/assets/image_1740551835302.png =438)
+
+### 修改账户名称或服务实例名称
+
+账户名称（account\_name）和服务实例名称（instance\_name）均为全局唯一名称，生成后不允许进行修改。
+

+# 使用 Zettapark 管理 Lakehouse Volume 的文件
+
+## 1. 概述
+
+云器 Lakehouse 通过其抽象存储层（[Volume](datalake_volume.md)、[Schema](SCHEMA.md) 和 [表](Tables.md)）和 Python API，提供对数据湖文件和数据仓库表的统一管理。本指南展示了如何在数据湖中执行文件管理操作，包括上传（PUT）、下载（GET）和列出（LIST）文件。
+
+**关键概念**：
+
+* **Volume存储抽象**：所有数据湖存储都映射到Volume对象。
+  * [External Volume](external_volume.md)：由客户管理，支持与 AWS S3 和阿里云 OSS 等云存储的集成。
+  * [Internal Volume](internal_volume.md)：由云器管理，分为USER VOLUME 和 TABLE VOLUME。
+* [Zettapark](ZettaparkQuickStart.md) **Python API**：提供文件和表集成的统一接口。
+
+你可以从[GitHub 存储库获取源代码（Jupyter Notebook ipynb 文件）](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/Zettapark/Managing%20Files%20on%20Datalake%20Volume%20with%20Zettapark.ipynb)。
+
+## 2. 环境设置
+
+### 1. 安装依赖项
+
+```bash
+pip install clickzetta_zettapark_python -U -i https://pypi.tuna.tsinghua.edu.cn/simple
+```
+
+### 2. 导入库并创建会话
+
+```python
+from clickzetta.zettapark.session import Session
+import json
+
+# 从配置文件加载连接参数
+with open('config.json', 'r') as config_file:
+    config = json.load(config_file)
+
+# 创建会话
+session = Session.builder.configs(config).create()
+print("会话创建成功！")
+```
+
+## 3. 文件操作
+
+### 1. 清理USER VOLUME
+
+在开始之前，清理USER VOLUME以确保环境干净：
+
+```python
+session.sql("REMOVE USER VOLUME SUBDIRECTORY '/'").show()
+```
+
+### 2. 列出USER VOLUME中的文件
+
+确认用户卷为空：
+
+```python
+session.sql("LIST USER VOLUME").show(10)
+```
+
+### 3. 上传文件到USER VOLUME
+
+根据文件类型将本地文件上传到用户卷的不同目录：
+
+```python
+import os
+
+# 遍历本地目录并上传文件
+for filename in os.listdir("data/"):
+    if filename.endswith("csv.gz"):
+        file_path = os.path.join("data/", filename)
+        session.file.put(file_path, "volume:user://~/csvgz/")
+    elif filename.endswith(".csv"):
+        file_path = os.path.join("data/", filename)
+        session.file.put(file_path, "volume:user://~/csv/")
+    elif filename.endswith(".json"):
+        file_path = os.path.join("data/", filename)
+        session.file.put(file_path, "volume:user://~/json/")
+    elif filename.endswith(".png"):
+        file_path = os.path.join("data/", filename)
+        session.file.put(file_path, "volume:user://~/png/")
+    elif filename.endswith(".jpg"):
+        file_path = os.path.join("data/", filename)
+        session.file.put(file_path, "volume:user://~/jpg/")
+    elif filename.endswith(".pdf"):
+        file_path = os.path.join("data/", filename)
+        session.file.put(file_path, "volume:user://~/pdf/")
+```
+
+### 4. 验证上传结果
+
+确认文件已成功上传：
+
+```python
+session.sql("LIST USER VOLUME").show(100)
+```
+
+## 4. 查看和下载文件
+
+### 1. 下载图像文件
+
+从用户卷下载图像并显示：
+
+```python
+from PIL import Image
+
+# 将图像下载到本地目录
+source_path = "volume:user://~/png/unstructured_tables.png"
+dest_path = "tmp/png/"
+session.file.get(source_path, dest_path)
+

+# 将Snowflake的实时ETL Pipeline迁移到云器Lakehouse
+
+## 亮点
+
+本文基于云器Lakehouse，快速实现了将Snowflake的实时ETL Pipeline迁移到云器Lakehouse，并发现基于云器Lakehouse的方案具备如下独特优势：
+
+* 全球多云支持。本方案中云器Lakehouse和Snowflake都基于AWS，提供了云体验的一致性。同样本方案也适合在GCP上的迁移。同时云器Lakehouse还支持阿里云、腾讯云、华为云，而不仅仅是海外主流云服务提供商的支持。
+* 迁移成本低。
+  * 云器Lakehouse提供了和Snowflake非常相似的产品概念，这对熟悉Snowflake的用户而言，非常容易理解和上手。
+  * 云器Lakehouse的SQL语法和Snowflake高度兼容，只需要做很少的Tiny修改即可实现代码迁移。
+* 运维成本低
+  * 云器Lakehouse提供了内置的Python运行环境并和SQL等任务实现统一的调度、运维和监控。不需要额外的Airflow服务、Python运行环境，大幅简化了系统架构，降低了运维难度和成本。

+## Real-Time Insurance Data ETL Pipeline with Snowflake项目介绍
+
+### 项目概况
+
+如果你熟悉Snowflake的实际操作和应用，那么Github上的[Real-Time Insurance Data ETL Pipeline with Snowflake](https://github.com/ravishankar324/Real-Time-Insurance-claims-Data-ETL-Pipeline) 对你是再熟悉不过了。该项目涉及在Snowflake中创建实时 ETL（提取、转换、加载）数据管道，以处理来自 Kaggle 的保险数据并将其加载到 Snowflake 中。数据管道使用 Apache Airflow 进行管理，涉及几个步骤来清理、规范化和转换数据，然后将其加载到 Snowflake 进行进一步处理。AWS S3 用作数据湖，用于存储原始数据和转换后的数据。
+
+开发完该项目后，可以根据需求安排 Airflow DAG 运行，确保 ETL 流程以所需的频率执行。最终清理、规范化和转换后的数据将可在 Tableau 中进行实时可视化，从而获得最新的见解和报告。项目架构图如下:
+
+:-: ![](.topwrite/assets/image_1737353888502.png =814)
+
+### 使用的工具和服务
+
+* **Python**：用于脚本编写和数据处理。
+* **Pandas**：用于数据操作和分析。
+* **AWS S3**：作为存储原始数据和转换后数据的数据湖。
+* **Snowflake**：用于数据建模和存储。
+* **Apache Airflow**：用于协调 ETL 工作流程。
+* **EC2**：用于托管 Airflow 环境。
+* **Kaggle API**：用于从 Kaggle 提取数据。
+* **Tableau**：用于数据可视化。
+
+### ETL 工作流
+
+1. **数据提取**
+
+   * 创建 Airflow DAG 脚本，使用 Kaggle API 从 Kaggle 保险数据集中提取随机数量的行。
+
+   * 清理、规范化并将数据转换为四个表：
+
+     * `policy_data`
+     * `customers_data`
+     * `vehicles_data`
+     * `claims_data`
+
+2. **数据存储**
+
+   * 将转换后的数据存储在 S3 存储桶中，并针对每种类型的规范化数据 ( `policy_data`、`customers_data`、`vehicles_data`、`claims_data`) 组织到不同的文件夹中。
+
+3. **Snowflake中的数据处理**
+
+   * 创建 Snowflake SQL 工作表来定义数据库模式。
+   * 在 Snowflake 中为每种类型的规范化数据创建暂存表。
+   * 定义 Snowpipes 以自动将数据从 S3 存储桶提取到暂存表。
+   * 为每个暂存表创建流对象以捕获变化。
+   * 创建最终表以合并来自流对象的新数据，确保仅插入不同的或新的行。
+
+4. **使用 Snowflake 流和任务更改数据捕获**
+
+   * 在 Snowflake 中创建任务以自动捕获变更数据。
+   * 当流对象中有新数据可用时，将触发每个任务以将数据加载到最终表中。
+
+5. **Airflow DAG 任务**
+
+   * **任务 1**：检查 Kaggle API 是否可用。
+   * **任务 2**：将转换后的数据上传到 S3 存储桶。

+# 将Spark数据工程最佳实践项目迁移到云器Lakehouse
+
+## 新方案亮点
+
+* **全面云化，聚焦数据**：将线下管理的环境全部迁移到云上，免去资源准备、系统运维等非数据相关的工作。
+* **易于迁移**：云器 Lakehouse SQL、Zettapark 与 Spark SQL、pySpark 分别具有高度兼容性，代码迁移的难度与成本极低。
+* **降低总体成本与复杂度**：云器 Lakehouse 内置工作流服务与数据质量控制服务，无需单独的 Airflow 和 Great Expectations。极大程度简化了系统架构，降低了总体成本与复杂度。
+* **具备开放性**：同时能够在架构中保留 Airflow 和 Greate Expectations，借助 Airflow 调度 Python 任务，并在 Python 代码中持续调用 Great Expectations 开展数据质量检测。
+* **资源管理与任务队列管理**：分别运用不同的 Virtual Cluster 处理 ETL、BI 以及数据质量的作业，达成资源隔离与任务队列管理。
+
+## Spark数据工程最佳实践项目介绍
+
+### Spark数据工程最佳实践项目背景
+
+在缺乏充分指导的情形下构建数据管道，可能会令人感到无所适从，难以判定自身是否遵循了最佳实践。倘若您身为一名数据工程师，期望明晰自身技术技能在构建数据管道方面的发展状况，但对是否遵循了行业标准存疑，也不确定能否与大型科技公司的数据工程师相较，那么 GitHub 上的 [Spark数据工程最佳实践](https://github.com/josephmachado/data_engineering_best_practices/tree/main) 项目便是为您量身定制的。本文将对设计数据管道、洞悉行业标准、考量数据质量以及编写可维护且易于操作的代码的最佳实践予以回顾。完成此项目后，您将洞悉设计数据管道的关键组件及其需求，并且能够迅速熟悉任何新的代码库。
+
+### Spark数据工程最佳实践项目场景
+
+假设我们从上游来源提取客户和订单信息，并创建订单数量的每小时报告。
+
+:-: ![](.topwrite/assets/image_1737530842475.png =405)
+
+使用的组件和环境如下：
+
+* 数据存储：MinIO with Delta Table Format
+* 数据处理：Spark
+* 代码语言：PySpark + Spark SQL
+* 数据质量：Great Expectations
+* 工作流：Airflow
+* 运行环境：本地Docker（Spark、Airflow）
+
+### Spark数据工程最佳实践项目最佳实践
+
+#### 使用标准模式逐步转换数据
+
+遵循既定的数据处理流程有助于处理常见的潜在问题，并且您可参考大量的资料。大多数行业标准模式均遵循三层数仓架构，具体如下：
+
+1. **原始层**：按上游源端的原始状态存储数据。此层有时会涉及数据类型的更改和列名的标准化。
+2. **转换层**：依据所选的建模原则对原始层的数据进行转换，从而形成一组表。常见的建模原则包括维度建模（Kimball）、Data Vault 模型、实体关系数据模型等。
+3. **消费层**：将来自转换层的数据加以组合，形成直接与最终用户用例相对应的数据集。消费层通常涉及连接和聚合转换层表，以方便最终用户对历史性能进行分析。**业务特定的指标**通常在此层定义。我们应确保**一个指标仅在一个位置定义**。
+4. **接口层（可选）**：消费层中的数据通常会遵循数据仓库的命名/数据类型等。然而，呈现给最终用户的数据应具备易用性和易理解性。接口层通常是作为仓库表与其消费者之间接口的**视图**。
+
+:-: ![](.topwrite/assets/image_1737530923177.png =808)
+
+^
+
+上图中的青铜层（Bronze Layer）、白银层（Silver Layer）、黄金层（Gold Layer）和接口层（User Interface）分别与上述的原始层、转换层、消费层和接口层相对应。我们针对白银层采用了维度建模的方法。对于管道/转换函数/表而言，输入被称为“上游”，输出则被称为“下游”消费者。在规模较大的公司中，多个团队在不同的层级上开展工作。数据采集团队或许会将数据导入青铜层，而其他团队能够依据自身需求构建属于自己的白银层和黄金层的表。
+
+^
+
+#### 在将数据提供给消费者之前确保数据有效（又称为数据质量检查）
+
+在构建数据集时，明确对数据的期望至关重要。对数据集的期望可以简单到列值符合要求，也可以复杂到满足更复杂的业务需求。若下游消费者使用了不良数据，其后果可能是灾难性的。例如，向客户发送错误的数据或基于不正确的数据进行资金支出。纠正不良数据使用的过程通常需要耗费大量时间，并重新运行所有受影响的流程！
+
+为防止消费者意外使用不良数据，我们应当在提供数据以供使用之前对其进行检查。
+
+本项目使用[Great Expectations](https://www.startdataengineering.com/post/ensuring-data-quality-with-great-expectations/) 库来定义和运行数据检查。
+
+#### 使用幂等的数据管道避免数据重复
+
+重跑，即重新运行数据管道，是一种常见操作。在重新运行数据管道时，我们必须确保输出不包含重复的行。系统在给定相同输入的情况下始终产生相同输出的特性称为幂等性。
+
+以下展示了重新运行数据管道时避免数据重复的两种技术：
+
+1. **基于运行 ID 的覆盖**：用于仅附加输出数据。请确保您的输出数据具有运行 ID 作为分区列（例如，我们的黄金表中的分区列）。运行 ID 表示创建的数据所属的时间范围。当重新处理数据时，依据给定的运行 ID 进行覆盖。
+2. **基于自然键的 UPSERTS**：在管道使用自然键对输出数据执行插入和更新时使用。当需要更新现有行的维度数据时（例如 SCD2 采用此方法）。重新运行管道产生的重复会致使现有行的更新（而非在输出中创建新行）。我们使用此方法来填充 dim\_customer 表。

+
+#### 监控告警配置
+
+下一步可以导航到运维监控->监控告警，增加告警规则，实现对ETL任务和数据质量控制的实时告警。
+
+^
+
+**使用内置的监控告警规则**：
+
+在系统内部，内置了如下通用的监控告警规则，在数据质量校验失败时，会按照规则中的具体配置来触发邮件、短信、电话等告警。
+
+:-: ![](.topwrite/assets/image_1737600310887.png =720)
+
+^
+
+**使用自定义监控告警规则**：
+
+上述内置的监控告警规则，是对全局所有的质量监控规则的校验结果都生效。如果想进一步精细化控制告警的监测范围和告警策略，也可以自定义的新建规则，如下图所示，选择“质量规则校验失败”的监控事项，并给定限制范围的过滤条件。监控告警配置的详细指南，可以参考 [监控告警](monitoring_and_alerting.md) 使用指南。

+# N8N中集成Lakehouse MCP Server
+
+N8N 的 Agent 节点支持直接集成来自外部 [MCP](https://modelcontextprotocol.io/introduction) 服务器的[工具](https://modelcontextprotocol.io/docs/concepts/tools)。这为 Lakehouse 与您的 N8N AI 工作流集成提供了新方式。
+Lakehouse MCP Server 通过这种方式实现与 N8N 的集成，来自 Lakehouse MCP Server 的丰富工具可以在 N8N 的 Agent 节点中轻松调用。
+
+首先，您需要部署支持 [SSE协议的Lakehouse MCP Server](LakehouseMCPServer_intro.md)。
+
+## 在 N8N 工作流 AI Agent 节点中增加 MCP Client
+
+N8N MCP 客户端工具节点是一个[模型上下文协议 (MCP)](https://modelcontextprotocol.io/introduction)客户端，允许您使用外部 MCP 服务器公开的工具。您可以将 MCP 客户端工具节点连接到您的模型，以便使用 N8N 代理调用外部工具。**目前 N8N 仅支持 SSE 协议，还不支持通过 HTTP 协议与 MCP Server 互通**。
+
+:-: ![](.topwrite/assets/image_1756887369109.png =795)
+
+在 Agent 节点的 System Message 中填写：
+您是 ClickZetta Lakehouse 资深产品专家，擅长借助 MCP Server Tools 帮助用户回答和解决问题，避免编造。对于 ClickZetta Lakehouse 相关的问题，如果没有合适的 MCP Tool，您需要先通过 `get_product_knowledge` 这个 MCP Tool 查询产品知识库获得知识，然后再通过合适的 Tool 执行获得结果。
+
+## 配置AI Agent节点的MCP
+
+使用以下参数配置节点。
+
+* **SSE 端点**：您要连接的 MCP 服务器的 SSE 端点。
+
+* **身份验证**：用于向 MCP 服务器进行身份验证的身份验证方法。选择 **“无”** 则无需身份验证即可尝试连接。
+
+* **要包含的工具**：选择要向 AI 代理公开的工具：
+
+  * **全部**：公开 MCP 服务器提供的所有工具。
+  * **已选择**：激活 **要包含的工具** 参数，您可以在其中选择要向 AI 代理公开的工具。
+  * **除以下所有**：激活 **要排除的工具** 参数，您可以在其中选择要避免与 AI 代理共享的工具。AI 代理将可以访问所有未选中的 MCP 服务器工具。
+
+:-: ![](.topwrite/assets/image_1756887446000.png =614)
+
+选择 **已选择**，即可看到 Tools 列表：

+
+### 💡 **Lakehouse分区的核心优势**
+
+* **智能化分区裁剪**：查询时无需手动指定分区条件，系统自动优化
+* **简化的分区管理**：告别复杂的分区维护，专注业务逻辑
+* **更好的性能可预测性**：避免过度分区，确保稳定的查询性能
+* **现代化架构设计**：基于Apache Iceberg的先进分区理念
+
+***
+
+## 核心差异和优势理解
+
+### 🚀 **Lakehouse分区的5大创新特性**
+
+#### 1. **智能转换分区函数**
+
+**创新价值**：避免与标准SQL函数冲突，提供更精确的时间分区控制
+
+```sql
+-- ✅ Lakehouse的优雅设计
+CREATE TABLE events PARTITIONED BY (days(event_date));  -- 精确的天级分区
+
+-- 💡 为什么使用复数形式？
+-- 避免与SQL标准函数year(), month()等冲突
+-- 提供更清晰的语义：years = 年数，而不是提取年份
+-- 返回值是计算后的数值：days('2024-06-01') = 19875
+-- years('2024-06-01') = 54（从1970年开始计算的年份偏移）
+```
+
+**迁移时的理解要点**：
+
+* `years/months/days/hours` 是复数形式，语义更准确
+* 转换分区避免逻辑冲突，确保分区策略的一致性
+* 返回值是计算后的数值，系统自动处理转换逻辑
+* 时间函数计算基准：years 从 1970 年开始，days 从 1970-01-01 开始
+
+#### 2. **隐藏分区的自动优化**
+
+**创新价值**：用户无需关心分区实现细节，专注业务逻辑
+
+```sql
+-- ✅ Lakehouse中的简洁查询
+SELECT * FROM sales WHERE order_date = '2024-06-01';  
+-- 系统自动转换为分区条件，无需手动指定分区
+
+-- 🎯 对比传统方式的优势
+-- 1. 查询更简洁，无需复杂的分区条件
+-- 2. 分区策略变更不影响查询逻辑
+-- 3. 系统自动选择最优的分区扫描策略
+```
+
+#### 3. **智能分区数量控制**
+
+**设计理念**：分区数量限制是性能保护机制，鼓励更好的分区设计
+
+```sql
+-- 💡 Lakehouse的分区哲学：质量优于数量
+-- 传统思维：尽可能细分分区
+-- Lakehouse理念：合理分区粒度 + 索引优化
+
+-- ✅ 推荐的高效设计
+CREATE TABLE user_events (
+    event_id INT,
+    user_id INT,
+    event_data JSON,
+    event_time TIMESTAMP_LTZ
+) PARTITIONED BY (days(event_time));  -- 时间分区（主要）
+
+CREATE BLOOMFILTER INDEX idx_user ON TABLE user_events(user_id);  -- 索引优化（辅助）
+
+-- 🎯 优势：避免小文件问题，确保每个分区有足够数据量
+-- 📊 限制说明：建议单次操作控制在合理范围内，避免过多小分区
+```
+
+#### 4. **转换分区的逻辑一致性**
+
+**设计原则**：避免冲突的分区维度，确保分区逻辑清晰
+
+< '2025-01-01'  -- 年级过滤
+```
+
+#### 5. **类型安全的分区设计**
+
+**安全保障**：通过类型检查避免数据写入错误
+
+```sql
+-- 💡 Lakehouse的类型安全机制
+CREATE TABLE orders (
+    id INT,
+    amount DOUBLE
+) PARTITIONED BY (order_date STRING);  -- 明确的STRING类型
+
+-- ⚠️ 类型不匹配会报错
+INSERT INTO orders VALUES (1, 100.0, '2024-06-01');  -- 字符串写入STRING分区：正确
+INSERT INTO orders VALUES (1, 100.0, DATE('2024-06-01'));  -- DATE写入STRING分区：错误
+
+-- ✅ 推荐做法：使用转换分区避免类型问题
+CREATE TABLE orders_safe (
+    id INT,
+    amount DOUBLE,
+    order_timestamp TIMESTAMP_LTZ
+) PARTITIONED BY (days(order_timestamp));  -- 让系统处理类型转换
+```
+
+### 🔄 **认知升级：从复杂到简洁**
+
+#### **传统分区 vs Lakehouse分区**
+
+| 维度         | 传统分区思维     | Lakehouse分区理念 | 优势          |
+| ---------- | ---------- | ------------- | ----------- |
+| **分区策略**   | 越细越好，多维度分区 | 合理粒度，重点维度     | 避免小文件，性能稳定  |
+| **查询方式**   | 必须指定分区条件   | 自动分区裁剪        | 查询更简洁，维护更容易 |

+## 🔍 **分区表创建验证（最佳实践**）
+
+### ⚡ **创建后验证：确保分区表正确生效**
+
+无论使用什么方式创建分区表（SQL、工具、脚本），都建议创建后立即验证。这是确保分区功能正常的最佳实践。
+
+#### 推荐的创建和验证流程
+
+```sql
+-- 1. 创建分区表（推荐使用原生SQL以确保语法准确）
+CREATE TABLE orders_partitioned (
+    id INT,
+    amount DOUBLE,
+    order_date DATE
+) PARTITIONED BY (days(order_date));
+
+-- 2. 立即验证分区表是否正确创建（必做步骤）
+SHOW PARTITIONS orders_partitioned;
+-- ✅ 正确：显示分区列表或空列表
+-- ❌ 异常：报错 "not a partitioned table"
+```
+
+#### 完整验证清单（每次创建后执行）
+
+```sql
+-- 🔍 验证步骤1：确认是分区表
+SHOW PARTITIONS orders_partitioned;
+
+-- 🔍 验证步骤2：测试数据插入和分区创建
+INSERT INTO orders_partitioned VALUES (1, 100.50, DATE('2024-06-01'));
+SHOW PARTITIONS orders_partitioned;
+-- ✅ 正确：显示类似 "days(order_date)=19875" 的分区
+
+-- 🔍 验证步骤3：验证分区裁剪生效
+SELECT * FROM orders_partitioned WHERE order_date = '2024-06-01';
+-- 应该能正常返回数据，且性能良好
+
+-- 🔍 验证步骤4：检查表结构
+DESCRIBE TABLE orders_partitioned;
+-- 确认列结构正确，分区字段类型匹配
+
+-- 🔍 验证步骤5：测试最大分区获取（兼容性验证）
+SELECT max_pt('orders_partitioned');
+-- 应该返回最大的分区值，用于兼容原平台的类似功能
+```
+
+#### 验证失败时的解决方案
+
+| 验证失败现象                      | 可能原因          | 解决方案       |
+| --------------------------- | ------------- | ---------- |
+| `not a partitioned table`   | 建表语法错误或工具创建异常 | 用原生SQL重新创建 |
+| `implicit cast not allowed` | 分区字段类型不匹配     | 检查插入数据类型   |
+| 无分区显示                       | 分区函数语法错误      | 检查是否用了复数形式 |
+| 性能无提升                       | 查询未利用分区字段     | 优化WHERE条件  |
+
+**为什么需要验证**？
+
+* 确保分区定义语法正确，避免性能问题
+* 及早发现配置错误，减少后续排查成本
+* 验证分区策略是否符合查询模式

+
+## 📊 **SHOW PARTITIONS 完整功能指南**
+
+### **基础语法和高级用法**
+
+```sql
+-- 完整语法
+SHOW PARTITIONS [EXTENDED] table_name 
+[ PARTITION ( partition_col_name = partition_col_val [, ...] ) ] 
+[WHERE <expr>
+
+### **基础用法**
+
+```sql
+-- 查看所有分区
+SHOW PARTITIONS sales_table;
+
+-- 查看分区详细信息
+SHOW PARTITIONS EXTENDED sales_table;
+
+-- 查看特定分区
+SHOW PARTITIONS sales_table PARTITION (pt1 = '2023');
+
+-- 多级分区过滤
+SHOW PARTITIONS sales_table PARTITION (pt1 = '2023', pt2 = '01');
+
+-- 限制返回数量
+SHOW PARTITIONS EXTENDED sales_table LIMIT 10;
+```
+
+### **高级用法：分区健康检查神器**
+
+⚠️ **重要限制**：`SHOW PARTITIONS` 不支持 `ORDER BY` 子句，如需排序请使用 WITH 子查询。
+
+< 100*1024*1024;
+
+-- 🔍 分区信息查看（支持LIMIT）
+SHOW PARTITIONS EXTENDED table_name LIMIT 10;
+
+-- 🔍 分区排序（通过WITH子查询实现）
+WITH partition_info AS (
+    SELECT partitions, bytes, total_rows, total_files, created_time
+    FROM (SHOW PARTITIONS EXTENDED table_name)
+)
+SELECT * FROM partition_info ORDER BY CAST(bytes AS BIGINT) DESC LIMIT 10;
+```
+
+### **MAX_PT 函数 - 获取最新分区**
+
+```sql
+-- 💡 MAX_PT函数：获取分区表中最大分区的值
+-- 语法：max_pt('schema_name.table_name' | 'table_name')
+
+-- 基本用法：查询最新分区的数据
+SELECT * FROM sales_table WHERE pt = max_pt('sales_table');
+
+-- 跨schema使用
+SELECT max_pt('prod_schema.sales_table');
+
+-- 实际应用场景：
+-- 1. 增量数据处理：总是处理最新分区
+INSERT INTO target_table 
+SELECT * FROM source_table 
+WHERE pt = max_pt('source_table');
+
+-- 2. 数据质量检查：检查最新分区的数据质量
+SELECT COUNT(*), AVG(amount), MAX(created_time)
+FROM orders 
+WHERE pt = max_pt('orders');
+```
+
+**MAX_PT 函数的迁移价值**：
+
+* **MaxCompute用户**：直接替代原有的max\_pt函数，无需修改查询逻辑
+* **Hive用户**：简化复杂的最大分区查询，提高开发效率
+* **其他平台用户**：提供便捷的最新数据查询方式
+

+
+## 🏗️ **高级分区表创建指南**
+
+### **分区 + 分桶 + 排序组合**
+
+```sql
+-- ✅ 方案1：分区 + 分桶（推荐用于散列分布）
+CREATE TABLE events_clustered (
+    user_id INT,
+    event_type STRING,
+    event_data JSON,
+    event_time TIMESTAMP_LTZ
+) PARTITIONED BY (days(event_time))
+  CLUSTERED BY (user_id) INTO 32 BUCKETS;
+
+-- ✅ 方案2：分区 + 排序（推荐用于范围查询）
+CREATE TABLE events_sorted (
+    user_id INT,
+    event_type STRING,
+    event_data JSON,
+    event_time TIMESTAMP_LTZ
+) PARTITIONED BY (days(event_time))
+  SORTED BY (event_type);
+
+CREATE TABLE events_both
+(
+    user_id INT,
+    event_type STRING,
+    event_data JSON,
+    event_time TIMESTAMP_LTZ
+)
+ PARTITIONED BY (days(event_time))
+CLUSTERED BY (user_id) 
+SORTED BY (event_type)
+INTO 32 BUCKETS;
+```
+
+### **bucket函数使用指南**
+
+**参数范围和建议**：
+
+```sql
+-- ✅ 推荐的bucket数量范围
+CREATE TABLE sales PARTITIONED BY (
+    days(sale_date),
+    bucket(10, user_id)    -- 推荐：1-1000的合理范围
+);
+
+-- 📊 bucket数量选择指南：
+-- 1-10个桶：适合小数据量表（<100万行）
+-- 10-100个桶：适合中等数据量表（100万-1000万行）
+-- 100-1000个桶：适合大数据量表（>
+
+### **复杂数据类型支持**
+
+```sql
+-- ✅ Lakehouse支持所有现代数据类型的分区
+CREATE TABLE modern_table (
+    user_id INT,
+    user_profile STRUCT<name: STRING, age: INT, location: STRING>,
+    tags ARRAY<STRING>,
+    metadata MAP<STRING, STRING>,
+    config JSON,
+    created_date DATE,
+    created_timestamp TIMESTAMP_LTZ,
+    created_timestamp_ntz TIMESTAMP_NTZ
+) PARTITIONED BY (days(created_date));
+
+-- 📝 支持的分区字段类型：
+-- 基础类型：INT, BIGINT, STRING, DATE, TIMESTAMP_LTZ, TIMESTAMP_NTZ
+-- 转换分区：years(), months(), days(), hours(), bucket()
+-- 不支持：STRUCT, ARRAY, MAP, JSON作为直接分区字段
+```
+
+### **分区值的特殊情况处理**
+
+```sql
+-- 💡 NULL值分区处理
+CREATE TABLE user_regions (
+    user_id INT,
+    region STRING  -- 允许NULL值
+) PARTITIONED BY (region);
+
+INSERT INTO user_regions VALUES (1, NULL);
+-- 结果：创建 region=NULL 的分区
+
+-- 💡 特殊字符支持
+INSERT INTO user_regions VALUES 
+(2, 'beijing'),           -- 正常字符
+(3, 'shang-hai'),         -- 支持破折号
+(4, 'guang_zhou'),        -- 支持下划线  
+(5, 'xi an'),             -- 支持空格
+(6, 'very_long_city_name_with_many_characters');  -- 支持长字符串
+
+-- 查看分区结果
+SHOW PARTITIONS user_regions;
+-- 结果显示：region=NULL, region=beijing, region=shang-hai, 等等
+
+-- 📝 特殊字符支持总结：
+-- ✅ 支持：字母、数字、下划线、破折号、空格、中文
+-- ✅ 长度：支持很长的分区值（测试过100+字符）
+-- ⚠️ 建议：避免使用特殊符号如@#$%等，虽然可能支持但不推荐
+```

+
+## 复杂分区迁移策略
+
+### 🏗️ **多级分区架构迁移挑战**
+
+如果您在原平台上已经实现了复杂的分区策略，迁移到Lakehouse时会遇到架构限制和设计选择问题。
+
+
+
+#### 复合维度分区的迁移挑战
+
+**原平台的复合分区**：
+
+```sql
+-- MaxCompute/Hive中常见的复合分区
+CREATE TABLE sales PARTITIONED BY (
+    dt STRING,           -- 日期：20240601
+    region STRING,       -- 地区：beijing, shanghai
+    channel STRING       -- 渠道：online, offline
+);
+
+-- 分区数量 = 日期数 × 地区数 × 渠道数
+-- 例如：365 × 10 × 3 = 10,950个分区/年
+```
+
+**❌ 直接迁移的问题**：
+
+<= '2024-06-30'  -- 分区裁剪
+  AND region = 'beijing'                     -- 索引加速
+  AND channel = 'online';                    -- 索引加速
+```
+
+**策略2：散列分区重设计**
+
+```sql
+-- 使用散列函数减少分区数量
+CREATE TABLE sales (
+    sale_id INT,
+    amount DOUBLE,
+    region STRING,
+    channel STRING,
+    sale_date DATE
+) PARTITIONED BY (
+    days(sale_date),           -- 时间分区
+    bucket(10, region)         -- 地区散列到10个桶
+);
+
+-- 分区数量 = 365 × 10 = 3,650个分区/年（可控）
+```
+
+### 🔄 **分区演化和维护策略迁移**
+
+#### 动态分区管理的差异
+
+**原平台的分区管理**：
+
+```sql
+-- Hive中的分区管理
+-- 1. 动态分区自动创建
+INSERT OVERWRITE TABLE target PARTITION(dt, region)
+SELECT ..., dt, region FROM source;  -- 自动创建所有dt×region组合
+
+-- 2. 分区修复
+MSCK REPAIR TABLE target;  -- 自动发现新分区
+
+-- 3. 分区删除
+ALTER TABLE target DROP PARTITION (dt<'20240101');  -- 批量删除
+```
+
+**Lakehouse中的等价实现**：
+
+```sql
+-- 1. 动态分区创建（需要注意分区数量）
+-- 建议先检查分区数量
+SELECT COUNT(DISTINCT CONCAT(dt, '/', region)) FROM source;
+
+-- 分批处理（如果数量较多）
+INSERT INTO target 
+SELECT ..., dt, region FROM source 
+WHERE dt BETWEEN '20240601' AND '20240615';
+
+-- 2. 分区发现（自动完成，无需手动修复）
+-- Lakehouse自动管理分区元数据
+
+-- 3. 分区清理（功能更强大）
+TRUNCATE TABLE target PARTITION (dt = '20240101');
+```
+
+#### 分区生命周期管理迁移
+
+**MaxCompute的自动生命周期**：
+
+```sql
+-- MaxCompute中设置表级生命周期
+ALTER TABLE events SET LIFECYCLE 90;  -- 90天后自动删除
+
+-- 分区级生命周期
+ALTER TABLE events PARTITION(dt='20240101') SET LIFECYCLE 30;  -- 单分区30天
+```
+
+**Lakehouse中的分区清理功能**：
+
+```sql
+-- 基础分区清理（针对STRING分区）
+TRUNCATE TABLE events PARTITION (dt = '20240101');
+
+-- 转换分区清理（需要使用具体分区值）
+TRUNCATE TABLE events_with_days PARTITION (days(event_date) = 19875);
+
+-- ✅ 高级功能：条件过滤清理
+-- 删除90天前的所有分区（需要先计算具体分区值）
+-- 对于STRING分区：
+TRUNCATE TABLE events 
+PARTITION (dt < date_format(date_sub(current_date(), 90), 'yyyyMMdd'));
+
+-- 复合条件清理：删除特定日期和地区的数据
+TRUNCATE TABLE sales 
+PARTITION (days(sale_date) = 19875 AND region = 'beijing');
+
+-- 批量分区清理：同时清理多个分区
+TRUNCATE TABLE logs 
+PARTITION (days(log_date) = 19875), 
+PARTITION (days(log_date) = 19876);
+```
+
+**分区清理最佳实践**：
+
+```sql
+-- 1. 清理前先检查要删除的分区
+SHOW PARTITIONS EXTENDED table_name 
+WHERE dt < '2024-01-01';
+
+-- 2. 分阶段清理大量分区（避免长时间锁表）
+-- 对于STRING分区：
+TRUNCATE TABLE large_table 
+PARTITION (dt = '20230101');
+-- 然后继续清理下一天的数据
+
+-- 对于转换分区，需要先查询分区值：
+-- SELECT days('2023-01-01'); -- 获取具体分区值
+TRUNCATE TABLE large_table_with_days
+PARTITION (days(date_col) = 具体分区值);
+
+-- 3. 定期清理调度脚本示例
+-- 每日凌晨2点执行，清理30天前的分区（STRING分区）
+TRUNCATE TABLE daily_logs 
+PARTITION (dt < date_format(date_sub(current_date(), 30), 'yyyyMMdd'));
+```
+
+### 🎯 **性能优化策略的迁移**
+
+#### Z-Order优化的等价实现
+
+**Databricks Delta Lake的Z-Order**：
+
+```sql
+-- Delta Lake中的多维优化
+OPTIMIZE events ZORDER BY (user_id, event_type, timestamp);
+-- 实现多个字段的联合优化
+```
+
+**Lakehouse中的等价策略**：
+
+```sql
+-- 策略1：分区+分桶组合（推荐）
+CREATE TABLE events (
+    user_id INT,
+    event_type STRING,
+    event_data JSON,
+    timestamp TIMESTAMP_LTZ
+) PARTITIONED BY (days(timestamp))    -- 时间分区
+  CLUSTERED BY (user_id) INTO 32 BUCKETS;  -- 用户散列分桶
+
+-- 策略2：分区+排序组合
+CREATE TABLE events_sorted (
+    user_id INT,
+    event_type STRING,
+    event_data JSON,
+    timestamp TIMESTAMP_LTZ
+) PARTITIONED BY (days(timestamp))    -- 时间分区
+  SORTED BY (event_type);             -- 事件类型排序
+
+-- 策略3：重写优化（类似OPTIMIZE）
+INSERT OVERWRITE events 
+SELECT * FROM events 
+ORDER BY user_id, event_type, timestamp;  -- 手动重排数据
+```
+
+#### 分区裁剪优化的迁移
+
+**原平台的分区裁剪逻辑**：
+
+```sql
+-- Spark中的复杂分区过滤
+df.filter(
+    (col("year") >
+
+**Lakehouse 中的等价查询**：
+
+< '2024-09-01'            -- month <= 8  
+  AND region = 'beijing';                  -- region = "beijing"
+
+-- 💡 关键：将复杂的分区逻辑转换为简单的时间范围查询
+```
+
+***
+
+## 分平台迁移注意事项
+
+### 🐘 **Hive用户特别注意**
+
+#### 语法兼容性差异
+
+```sql
+-- ✅ Hive语法在Lakehouse中仍然支持
+CREATE TABLE hive_style (
+    order_id INT,
+    amount DOUBLE
+) PARTITIONED BY (dt STRING, region STRING);  -- 完全兼容
+
+-- ⚠️ 但要注意ADD COLUMN的位置问题
+-- Hive: 新列会加到分区列之前的最后位置
+-- Lakehouse: 建议明确指定列位置
+ALTER TABLE hive_style ADD COLUMN new_col STRING AFTER amount;  -- 明确指定位置
+```
+
+#### 动态分区配置差异
+
+```sql
+-- Hive中需要的配置在Lakehouse中不需要
+-- set hive.exec.dynamic.partition=true;           -- Lakehouse中不需要
+-- set hive.exec.dynamic.partition.mode=nonstrict; -- Lakehouse中不需要
+
+-- 但要注意分区数量管理
+-- Hive: hive.exec.max.dynamic.partitions=1000（可调）
+-- Lakehouse: 建议单次操作控制在合理范围内
+```
+
+#### Hive用户的真实痛点补充
+
+```sql
+-- Hive用户常遇到的额外问题：
+-- 1. 分区字段类型限制
+CREATE TABLE hive_table PARTITIONED BY (dt STRING); -- Hive分区字段通常必须是STRING
+
+-- 2. 分区目录结构依赖
+-- Hive严格依赖 /data/table/year=2024/month=06/day=01/ 这样的目录结构
+-- Lakehouse中无此限制，更灵活
+
+-- 3. 分区修复的频繁需求
+-- Hive: MSCK REPAIR TABLE table_name;  -- 经常需要手动修复
+-- Lakehouse: 自动维护元数据，无需手动修复
+```
+
+### ⚡ **Spark用户特别注意**
+
+#### DataFrame写入方式差异
+
+```sql
+-- Spark DataFrame常见写入方式
+-- df.write.mode("overwrite").partitionBy("date", "region").saveAsTable("table")
+
+-- 迁移到Lakehouse SQL时需要注意
+-- 1. 确保表已经创建并正确分区
+CREATE TABLE spark_migrated PARTITIONED BY (date STRING, region STRING);
+
+-- 2. 使用INSERT语句而不是saveAsTable
+INSERT OVERWRITE spark_migrated SELECT * FROM source_data;
+```
+
+#### 转换函数名映射
+
+| Spark函数          | Lakehouse函数   | 说明     |
+| ---------------- | ------------- | ------ |
+| `year(col)`      | `years(col)`  | 注意复数形式 |
+| `month(col)`     | `months(col)` | 注意复数形式 |
+| `dayofyear(col)` | `days(col)`   | 函数名不同  |
+| `hour(col)`      | `hours(col)`  | 注意复数形式 |
+
+#### Spark用户的额外挑战
+
+```scala
+// Spark用户更常遇到的问题：
+// 1. 分区发现问题
+spark.sql("MSCK REPAIR TABLE table_name")  // Spark也有这个问题
+
+// 2. 动态分区写入的性能陷阱
+df.write.mode("append")
+  .option("maxRecordsPerFile", "50000")  // 控制文件大小
+  .partitionBy("date")
+  .saveAsTable("table")
+
+// 3. 分区列自动推断类型问题
+df.write.partitionBy($"date".cast("string"))  // 必须转string
+```
+
+### ☁️ **MaxCompute用户特别注意**
+
+#### 分区使用习惯调整
+
+```sql
+-- MaxCompute强制要求分区条件
+-- SELECT * FROM table WHERE pt='20240601';  -- 必须带分区条件，否则报错
+
+-- Lakehouse中分区条件是自动的
+SELECT * FROM table WHERE order_date='2024-06-01';  -- 自动分区裁剪，更灵活
+
+-- ⚠️ 但仍然建议在查询中包含分区条件以获得最佳性能
+```
+
+#### 生命周期管理差异
+
+```sql
+-- MaxCompute的自动生命周期
+-- ALTER TABLE table SET LIFECYCLE 30;  -- 30天后自动删除
+
+-- Lakehouse中需要手动管理或通过调度
+TRUNCATE TABLE table PARTITION (order_date = '2024-05-01');  -- 手动清理
+```
+
+#### MaxCompute用户的真实痛点
+
+```sql
+-- MaxCompute用户最常遇到的问题：
+-- 1. 强制分区过滤的习惯
+-- MaxCompute: 不带分区条件会直接报错
+-- Lakehouse: 允许全表扫描，但建议带分区条件
+
+-- 2. 分区表的INSERT OVERWRITE语法差异
+-- MaxCompute: INSERT OVERWRITE TABLE target PARTITION(dt='20240601')
+-- Lakehouse: INSERT OVERWRITE target ...（自动识别分区）
+
+-- 3. 跨项目访问语法变化
+-- MaxCompute: SELECT * FROM project.table WHERE pt='20240601';
+-- Lakehouse: SELECT * FROM catalog.schema.table WHERE pt='20240601';
+```
+
+### ❄️ **Snowflake用户特别注意**
+
+#### 🚨 **主要认知转变：从自动优化到主动分区设计**
+
+**传统Snowflake用户的习惯**：您可能较少关注底层分区设计
+
+```sql
+-- 传统Snowflake中的典型使用模式
+CREATE TABLE orders (id INT, amount DOUBLE, order_date DATE);  -- 系统自动管理存储
+ALTER TABLE orders CLUSTER BY (order_date);  -- 设置聚簇键，系统自动微分区管理
+
+-- 查询时完全不用考虑分区
+SELECT * FROM orders WHERE amount >
+
+**现代 Snowflake 用户（Iceberg 表）**：语法基本相似，但有细微差异
+
+```sql
+-- Snowflake Iceberg表
+CREATE ICEBERG TABLE orders_iceberg PARTITION BY (year(order_date));
+
+-- Lakehouse中的对应语法
+CREATE TABLE orders_lakehouse PARTITIONED BY (years(order_date));  -- 注意复数
+```
+
+**迁移到 Lakehouse 的调整**：
+
+```sql
+-- ❌ 传统Snowflake思维在Lakehouse中可能不够优化
+CREATE TABLE orders (id INT, amount DOUBLE, order_date DATE);  -- 创建了普通表，不是分区表
+-- 结果：查询性能可能不够理想
+
+-- ✅ 学会主动设计分区策略
+CREATE TABLE orders (
+    id INT, 
+    amount DOUBLE,
+    order_date DATE
+) PARTITIONED BY (days(order_date));  -- 主动设计分区
+
+-- 查询时虽然自动裁剪，但分区设计直接影响性能
+SELECT * FROM orders 
+WHERE order_date >= '2024-06-01'  -- 分区条件（建议包含）
+  AND amount > 1000;              -- 业务条件
+```
+
+#### Snowflake用户的学习路径
+
+```sql
+-- 阶段1：理解分区的价值
+-- 分区 = 物理上将数据按某个字段分别存储
+-- 目的：查询时只扫描相关分区，而不是全表
+
+-- 阶段2：学会分区设计
+-- 问自己：我的查询最常用哪个字段做过滤？
+-- 时间字段：order_date, created_at, updated_at
+-- 业务字段：region, department, customer_type
+
+-- 阶段3：验证分区效果
+-- 对比分区表 vs 非分区表的查询性能
+```
+
+#### Snowflake用户的认知重点
+
+```sql
+-- Snowflake用户需要重点理解：
+-- 1. 不是所有数据库都会自动优化
+SELECT * FROM large_table WHERE complex_condition;  -- 需要考虑分区设计
+
+-- 2. 分区设计的重要性
+-- Snowflake的micro-partitions是自动的，但Lakehouse中需要主动设计
+
+-- 3. 文件系统优化概念
+-- 理解"小文件问题"、"分区数量控制"等概念
+
+-- 4. 查询优化意识
+SELECT * FROM large_partitioned_table 
+WHERE order_date >= '2024-06-01';  -- 包含分区条件的查询习惯
+```
+
+### 🧱 **Databricks 用户特别注意**
+
+#### Delta Lake vs Iceberg差异
+
+```sql
+-- Delta Lake的分区语法
+-- CREATE TABLE delta_table PARTITIONED BY (year, month);
+
+-- Lakehouse (Iceberg)中的等价语法
+CREATE TABLE iceberg_table PARTITIONED BY (years(date_col));  -- 只能用单一时间粒度
+
+-- ⚠️ 不能像Delta Lake那样同时使用多个时间粒度
+```
+
+#### 优化命令差异
+
+```sql
+-- Delta Lake的优化命令
+-- OPTIMIZE table_name;
+-- OPTIMIZE table_name ZORDER BY (col1, col2);
+
+-- Lakehouse中通过重写实现类似效果
+INSERT OVERWRITE table_name SELECT * FROM table_name;  -- 文件合并优化
+```
+
+#### Databricks用户的高级功能迁移
+
+```sql
+-- Databricks用户更常遇到的问题：
+-- 1. Delta Lake的时间旅行习惯
+-- Delta: SELECT * FROM table TIMESTAMP AS OF '2024-01-01 00:00:00';
+-- Lakehouse: SELECT * FROM table TIMESTAMP AS OF '2024-01-01 00:00:00';  -- 语法相似
+
+-- 2. OPTIMIZE和Z-ORDER的重度依赖
+-- Delta: OPTIMIZE table ZORDER BY (col1, col2);  -- 这是日常操作
+-- Lakehouse: 需要通过分区+排序+分桶组合实现
+
+-- 3. Unity Catalog的影响
+-- Delta: CREATE TABLE catalog.schema.table;  -- 三层命名空间习惯
+-- Lakehouse: CREATE TABLE schema.table;  -- 两层命名空间
+```

+
+## 实战避坑指南
+
+### 分区创建避坑
+
+#### Do's and Don'ts 对比
+
+```sql
+-- ❌ 错误做法：不明确的分区设计
+CREATE TABLE bad_partition (
+    id INT,
+    data STRING,
+    timestamp_col TIMESTAMP_LTZ
+);  -- 没有PARTITIONED BY，不是分区表
+
+INSERT INTO bad_partition VALUES (1, 'test', CURRENT_TIMESTAMP());
+-- 后面发现查询慢，再想加分区就晚了
+
+-- ✅ 正确做法：提前规划分区策略
+CREATE TABLE good_partition (
+    id INT,
+    data STRING,
+    timestamp_col TIMESTAMP_LTZ
+) PARTITIONED BY (days(timestamp_col));
+
+-- 立即验证分区是否正确创建
+SHOW PARTITIONS good_partition;  -- 应该能正常执行，不报错
+```
+
+#### 分区字段类型选择
+
+```sql
+-- ❌ 容易踩坑的类型选择
+CREATE TABLE date_type_trap (
+    id INT,
+    order_date DATE  -- DATE类型
+) PARTITIONED BY (order_date);
+
+-- 插入数据时可能报类型错误
+INSERT INTO date_type_trap VALUES (1, '2024-06-01');  -- 字符串vs DATE类型
+
+-- ✅ 推荐做法：使用STRING类型分区
+CREATE TABLE string_partition (
+    id INT,
+    order_date_str STRING  -- 用STRING类型避免类型转换问题
+) PARTITIONED BY (order_date_str);
+
+-- 或者使用转换分区
+CREATE TABLE transform_partition (
+    id INT,
+    order_date DATE
+) PARTITIONED BY (days(order_date));  -- 让系统处理类型转换
+```
+
+### 数据写入避坑
+
+#### 大批量写入策略
+
+<= 'end_value';
+```
+
+#### 分区数据一致性
+
+```sql
+-- ⚠️ 注意：转换分区的时区问题
+CREATE TABLE timezone_sensitive (
+    id INT,
+    event_time TIMESTAMP_LTZ  -- 带时区的时间戳
+) PARTITIONED BY (days(event_time));
+
+-- 不同时区的相同本地时间可能落在不同分区
+INSERT INTO timezone_sensitive VALUES 
+(1, TIMESTAMP '2024-06-01 23:30:00 UTC'),      -- UTC时区
+(2, TIMESTAMP '2024-06-01 23:30:00');          -- 系统默认时区
+
+-- 查看分区分布
+SHOW PARTITIONS timezone_sensitive;
+-- 可能看到两个不同的分区值：days(event_time)=19875 和 days(event_time)=19876
+```
+
+### 查询性能避坑
+
+#### 分区裁剪失效场景
+
+```sql
+-- ❌ 无法利用分区裁剪的查询
+SELECT * FROM partitioned_table 
+WHERE YEAR(order_date) = 2024;  -- 函数包装分区字段
+
+SELECT * FROM partitioned_table 
+WHERE order_date LIKE '2024%';  -- 模糊匹配
+
+-- ✅ 能够有效分区裁剪的查询
+SELECT * FROM partitioned_table 
+WHERE order_date >
+
+### 🚨 **分区故障快速排查**
+
+#### 问题：分区表性能比非分区表还差
+
+**排查命令**：
+
+< 10*1024*1024;
+
+-- 4. 检查查询是否利用分区
+EXPLAIN SELECT * FROM your_table WHERE partition_col = 'value';
+```
+
+**常见原因和解决方案**：
+
+* **过度分区（分区太小太多**） → 重新设计分区粒度
+* **查询未包含分区字段** → 优化查询WHERE条件
+* **创建的不是真正的分区表** → 用原生SQL重建
+
+***
+
+## 分区性能验证实战指南
+
+### 🎯 **分区效果验证的标准方法**
+
+#### 1. 创建对比测试
+
+```sql
+-- 创建相同数据的分区表和非分区表
+CREATE TABLE sales_partitioned (
+    id INT, amount DOUBLE, sale_date DATE
+) PARTITIONED BY (days(sale_date));
+
+CREATE TABLE sales_normal (
+    id INT, amount DOUBLE, sale_date DATE
+);
+
+-- 插入相同的大量数据（建议>
+
+#### 2. 性能基准测试
+
+<= '2024-06-30';
+```
+
+#### 3. 分区健康检查
+
+```sql
+-- 检查分区大小分布
+SHOW PARTITIONS EXTENDED table_name;
+
+-- 理想状态：
+-- ✅ 每个分区 128MB - 1GB
+-- ✅ 分区大小相对均匀
+-- ❌ 大量小于10MB的小分区
+-- ❌ 单个分区超过5GB
+```
+
+### 📊 **性能问题诊断**
+
+#### 分区表比非分区表还慢？
+
+**可能原因与解决方案**：
+
+1. **过度分区**：分区太细，元数据开销大
+   ```sql
+   -- 问题：每小时分区，导致大量小分区
+   PARTITIONED BY (hours(timestamp))
+
+   -- 解决：改为天级分区
+   PARTITIONED BY (days(timestamp))
+   ```
+
+2. **查询未利用分区**：WHERE条件没有包含分区字段
+   ```sql
+   -- ❌ 无法利用分区
+   SELECT * FROM partitioned_table WHERE amount >
+
+3. **分区字段选择错误**：分区字段不是查询热点
+   ```sql
+   -- 问题分析：检查查询模式
+   -- 如果查询主要按user_id过滤，但按date分区，效果不佳
+
+   -- 解决：重新设计分区策略
+   PARTITIONED BY (bucket(100, user_id))  -- 改按用户散列分区
+   ```
+
+### 🎛️ **分区调优实战**
+
+#### 1. 分区粒度选择
+
+< 10K：月级分区 months()
+```
+
+#### 2. 复合分区优化
+
+```sql
+-- 原始复合分区问题
+CREATE TABLE sales_old PARTITIONED BY (region, sale_date, channel);
+-- 问题：10个地区 × 365天 × 3渠道 = 10,950分区
+
+-- 优化方案1：主次分区
+CREATE TABLE sales_optimized (
+    ..., region STRING, channel STRING
+) PARTITIONED BY (days(sale_date));  -- 主分区：时间
+CREATE BLOOMFILTER INDEX idx_region ON TABLE sales_optimized(region);
+CREATE BLOOMFILTER INDEX idx_channel ON TABLE sales_optimized(channel);
+
+-- 优化方案2：散列压缩
+CREATE TABLE sales_hash PARTITIONED BY (
+    days(sale_date),           -- 时间分区：365个
+    bucket(5, region)          -- 地区散列到5个桶
+);
+-- 结果：365 × 5 = 1,825分区（可控）
+```
+
+#### 3. 分区演化策略
+
+```sql
+-- 定期分区健康检查
+WITH partition_health AS (
+    SELECT 
+        partitions,
+        total_rows,
+        bytes,
+        CASE 
+            WHEN CAST(bytes AS BIGINT) < 10*1024*1024 THEN 'TOO_SMALL'
+            WHEN CAST(bytes AS BIGINT) >
+
+#### 迁移效果对比
+
+<= '2024-06-01 17:59:59';
+
+-- 性能提升：
+-- 📈 查询速度：提升40%（避免小分区扫描）
+-- 🔧 维护成本：降低60%（分区数量大幅减少）
+-- 📝 查询复杂度：降低80%（无需计算年月日时）
+```
+
+### 📋 **案例2：日志分析表迁移（MaxCompute → 云器Lakehouse**）
+
+#### 原始MaxCompute表
+
+```sql
+-- 原MaxCompute表：严格分区限制
+CREATE TABLE app_logs (
+    user_id STRING,
+    event_type STRING,
+    event_data STRING
+) PARTITIONED BY (
+    pt STRING,          -- 格式：20240601  
+    region STRING,      -- 地区：beijing, shanghai
+    app_version STRING  -- 版本：1.0, 1.1, 1.2
+);
+
+-- MaxCompute特点：
+-- ✅ 强制分区条件：SELECT必须带WHERE pt='20240601'
+-- ❌ 分区数量爆炸：365 × 10 × 20 = 73,000/年
+-- ❌ 数据倾斜：北京地区数据多，其他地区很少
+```
+
+#### 云器Lakehouse迁移策略
+
+```sql
+-- 步骤1：分析原有查询模式
+-- 发现：90%查询都是按时间范围 + 地区过滤
+-- 决策：时间作为主分区，地区用索引
+
+-- 步骤2：重设计分区架构
+CREATE TABLE app_logs_new (
+    user_id STRING,
+    event_type STRING,
+    event_data STRING,
+    region STRING,        -- 不分区，用索引
+    app_version STRING,   -- 不分区，用索引
+    log_date DATE
+) PARTITIONED BY (days(log_date));  -- 只按时间分区
+
+-- 步骤3：创建索引优化非分区查询
+CREATE BLOOMFILTER INDEX idx_region ON TABLE app_logs_new(region);
+CREATE BLOOMFILTER INDEX idx_version ON TABLE app_logs_new(app_version);
+
+-- 步骤4：验证查询性能
+-- 原查询：
+SELECT * FROM app_logs WHERE pt='20240601' AND region='beijing';
+
+-- 新查询：
+SELECT * FROM app_logs_new 
+WHERE log_date='2024-06-01' AND region='beijing';
+-- 结果：性能相当，但分区数量从73000降至365
+```
+
+#### 迁移过程中的挑战
+
+```sql
+-- 挑战1：数据类型不一致
+-- MaxCompute: pt STRING '20240601'
+-- 云器Lakehouse: log_date DATE '2024-06-01'
+
+-- 解决：ETL转换脚本
+INSERT INTO app_logs_new 
+SELECT 
+    user_id,
+    event_type, 
+    event_data,
+    region,
+    app_version,
+    DATE(CONCAT(
+        SUBSTR(pt, 1, 4), '-',
+        SUBSTR(pt, 5, 2), '-', 
+        SUBSTR(pt, 7, 2)
+    )) as log_date
+FROM maxcompute_source;
+
+-- 挑战2：习惯性写法需要调整
+-- MaxCompute习惯：WHERE pt='20240601'（字符串精确匹配）
+-- 云器Lakehouse：WHERE log_date='2024-06-01'（自动分区裁剪）
+
+-- 挑战3：最大分区查询方式变化
+-- MaxCompute原有：WHERE pt = max_pt()
+-- 云器Lakehouse新方法：WHERE log_date = (SELECT DATE(max_pt('app_logs_new')))
+-- 或者重新设计为STRING分区，直接使用：WHERE pt = max_pt('app_logs_new')
+```
+
+#### 分区维护自动化
+
+```sql
+-- MaxCompute风格的自动化脚本（适应新平台）
+-- 1. 每日清理30天前的分区
+TRUNCATE TABLE app_logs_new 
+PARTITION (log_date < current_date() - INTERVAL '30' DAY);
+
+-- 2. 智能清理：保留最新分区，清理小分区
+WITH old_partitions AS (
+    SELECT partitions
+    FROM (SHOW PARTITIONS EXTENDED app_logs_new)
+    WHERE CAST(bytes AS BIGINT) < 1000000  -- 小于1MB的分区
+      AND partitions < max_pt('app_logs_new') - INTERVAL '7' DAY
+)
+-- 逐个清理小分区（注意：需要具体分区值）
+
+-- 3. 分区健康检查脚本
+WITH partition_stats AS (
+    SELECT 
+        partitions,
+        CAST(total_rows AS BIGINT) as rows,
+        CAST(bytes AS BIGINT) as size_bytes
+    FROM (SHOW PARTITIONS EXTENDED app_logs_new)
+)
+SELECT 
+    COUNT(*) as total_partitions,
+    AVG(size_bytes)/1024/1024 as avg_size_mb,
+    SUM(CASE WHEN size_bytes < 10*1024*1024 THEN 1 ELSE 0 END) as small_partitions,
+    max_pt('app_logs_new') as latest_partition
+FROM partition_stats;
+```
+
+### 📋 **案例3：实时数据表迁移（Spark → 云器Lakehouse**）
+
+#### 原始Spark Delta表
+
+```sql
+-- 原Spark表：小时级分区 + Z-Order优化
+CREATE TABLE user_events USING DELTA
+PARTITIONED BY (date_hour STRING)  -- 格式：2024060109
+OPTIONS (
+  'path' '/data/user_events'
+);
+
+-- 定期优化
+OPTIMIZE user_events ZORDER BY (user_id, event_type);
+```
+
+#### 云器Lakehouse迁移挑战
+
+```sql
+-- 挑战1：没有直接的Z-Order等价功能
+-- 挑战2：小时级分区可能过细
+-- 挑战3：实时写入性能要求高
+
+-- 解决方案1：分区 + 分桶组合（推荐）
+CREATE TABLE user_events_new (
+    user_id INT,
+    event_type STRING,
+    event_data JSON,
+    event_time TIMESTAMP_LTZ
+) PARTITIONED BY (hours(event_time))      -- 保持小时级分区（实时需求）
+  CLUSTERED BY (user_id) INTO 32 BUCKETS; -- 用户ID分桶
+
+-- 解决方案2：分区 + 排序组合
+CREATE TABLE user_events_sorted (
+    user_id INT,
+    event_type STRING,
+    event_data JSON,
+    event_time TIMESTAMP_LTZ
+) PARTITIONED BY (hours(event_time))      -- 保持小时级分区
+  SORTED BY (event_type);                 -- 事件类型排序
+
+-- 实现类似Z-Order的效果：
+-- 1. 分区：按时间物理隔离
+-- 2. 分桶：按用户ID散列分布  
+-- 3. 排序：按事件类型聚集存储
+```
+
+#### 性能调优过程
+
+```sql
+-- 调优1：监控分区大小
+WITH partition_analysis AS (
+    SELECT 
+        partitions,
+        CAST(bytes AS BIGINT)/1024/1024 as size_mb,
+        CAST(total_rows AS BIGINT) as row_count
+    FROM (SHOW PARTITIONS EXTENDED user_events_new)
+)
+SELECT * FROM partition_analysis 
+ORDER BY size_mb DESC LIMIT 10;
+
+-- 发现问题：夜间分区太小（<10MB）
+-- 解决：动态调整分区策略
+
+-- 调优2：白天用小时分区，夜间合并
+-- 通过ETL实现智能分区策略：
+-- 8:00-22:00高峰期：小时级分区
+-- 22:00-8:00低峰期：合并到天级分区
+```
+
+### 📋 **案例4：数据仓库迁移（Snowflake → 云器Lakehouse**）
+
+#### Snowflake用户的特殊挑战
+
+```sql
+-- 传统Snowflake：自动存储管理
+CREATE TABLE sales (
+    order_id INT,
+    customer_id INT,
+    amount DECIMAL(10,2),
+    order_date DATE
+);
+
+-- 设置聚簇键（用户相对无感知）
+ALTER TABLE sales CLUSTER BY (order_date);
+
+-- 查询：不用特别关心物理存储
+SELECT * FROM sales WHERE amount >
+
+#### 云器Lakehouse学习路径
+
+```sql
+-- 第1阶段：理解分区概念
+-- 问题：什么是分区？为什么需要分区？
+-- 答案：分区是将数据按某个字段物理分开存储，查询时只扫描相关分区
+
+-- 第2阶段：学会分区设计
+-- 问题：应该按什么字段分区？
+-- 分析：检查最常用的WHERE条件
+SELECT 
+    COUNT(*) as query_count,
+    'order_date filter' as filter_type
+FROM query_log 
+WHERE query_text LIKE '%WHERE%order_date%'
+UNION ALL
+SELECT 
+    COUNT(*),
+    'customer_id filter' 
+FROM query_log 
+WHERE query_text LIKE '%WHERE%customer_id%';
+
+-- 结果：order_date过滤占80%，customer_id占20%
+-- 决策：按order_date分区，customer_id用索引
+
+-- 第3阶段：正确的分区表设计
+CREATE TABLE sales_partitioned (
+    order_id INT,
+    customer_id INT,
+    amount DECIMAL(10,2),
+    order_date DATE
+) PARTITIONED BY (days(order_date));
+
+CREATE BLOOMFILTER INDEX idx_customer ON TABLE sales_partitioned(customer_id);
+
+-- 第4阶段：验证性能提升
+-- 对比查询：
+SELECT * FROM sales WHERE order_date = '2024-06-01';           -- 全表扫描
+SELECT * FROM sales_partitioned WHERE order_date = '2024-06-01'; -- 分区扫描
+
+-- 结果：分区表通常有显著性能提升
+```
+
+#### Snowflake用户常见调整和实际困惑
+
+```sql
+-- 调整1：创建分区表而不是普通表
+CREATE TABLE sales_correct (
+    order_id INT,
+    amount DECIMAL(10,2),
+    order_date DATE
+) PARTITIONED BY (days(order_date));  -- ✅ 这是分区表
+
+-- 调整2：查询时包含分区条件
+SELECT * FROM sales_partitioned 
+WHERE order_date >= '2024-06-01'  -- ✅ 利用分区
+  AND amount > 1000;              -- ✅ 业务过滤
+
+-- 调整3：理解分区字段的重要性
+SELECT * FROM sales_partitioned WHERE amount > 1000;  -- 可以优化为包含分区条件
+
+-- 调整4：不是所有查询都会自动很快
+-- Snowflake用户习惯了系统自动处理一切存储优化
+-- Lakehouse中需要更多的主动设计意识
+```
+
+#### 认知转变的实际过程
+
+```markdown
+### Snowflake用户的常见疑问：
+"为什么我的查询在Snowflake上很快，在Lakehouse上需要考虑分区？"
+
+**答案**：Snowflake的自动优化 vs Lakehouse的主动分区设计各有优势
+
+### 学习过程中的典型问题：
+1. "为什么要我来决定分区策略？"
+2. "什么是小文件问题？我之前没考虑过文件大小"
+3. "分区数量控制是什么意思？"
+
+### 理解突破时刻：
+当用户看到分区表比非分区表有明显性能优势时，开始理解分区的价值
+```

+
+## 迁移验证清单
+
+### 📋 **分区创建验证**
+
+```sql
+-- ✅ 检查点1：表确实是分区表
+SHOW PARTITIONS your_table_name;
+-- 应该能正常执行，不报"not a partitioned table"错误
+
+-- ✅ 检查点2：分区字段类型正确
+DESCRIBE TABLE your_table_name;
+-- 确认分区字段的数据类型与预期一致
+
+-- ✅ 检查点3：测试数据写入
+INSERT INTO your_table_name VALUES (测试数据);
+SHOW PARTITIONS your_table_name;
+-- 应该能看到新创建的分区
+
+-- ✅ 检查点4：验证分区值格式
+-- 转换分区会生成数值，如 days('2024-06-01') = 19875
+-- years('2024-06-01') = 54（从1970年开始的年份计数）
+-- 确认分区值符合预期
+
+-- ✅ 检查点5：测试最大分区获取（兼容性验证）
+SELECT max_pt('your_table_name');
+-- 应该返回最大的分区值，用于兼容原平台的类似功能
+```
+
+### 📋 **性能验证**
+
+```sql
+-- ✅ 检查点6：分区裁剪是否生效
+-- 对比这两个查询的执行时间
+SELECT COUNT(*) FROM your_table_name;  -- 全表扫描
+SELECT COUNT(*) FROM your_table_name WHERE partition_col = 'specific_value';  -- 分区查询
+
+-- 分区查询应该明显更快
+
+-- ✅ 检查点7：分区大小是否合理
+SHOW PARTITIONS EXTENDED your_table_name;
+-- 检查每个分区的大小，理想范围：128MB - 1GB
+```
+
+### 📋 **兼容性验证**
+
+```sql
+-- ✅ 检查点8：原有查询语句是否需要修改
+-- 将原平台的查询语句在Lakehouse中测试
+-- 特别注意：
+-- 1. 转换函数名是否需要调整（year -> years）
+-- 2. 分区条件是否能自动识别
+-- 3. 数据类型转换是否正常
+
+-- ✅ 检查点9：分区演化策略是否可行
+-- 验证分区清理、维护脚本是否正常工作
+```

+
+## 总结：成功迁移的关键要素
+
+### 🎯 **核心认知转变**
+
+1. **从显式分区到隐藏分区**：不需要在每个查询中手动指定分区条件
+2. **从自动优化到主动设计**：分区策略需要提前规划和设计
+3. **从单一语法到多样选择**：支持多种分区创建方式，选择最适合的
+4. **从较少关注到分区意识**：特别是Snowflake等平台用户，需要增强分区设计意识
+5. **从复杂分区到简化设计**：多级分区需要重新设计为单一粒度分区
+
+### 🛡️ **避坑要点总结**
+
+#### 基础语法陷阱
+
+1. **转换函数名记住复数形式**：`years`, `months`, `days`, `hours`
+2. **分区类型保持一致**：避免STRING和DATE类型混用
+3. **分区数量控制在合理范围**：避免过多小分区
+4. **分区设计考虑查询模式**：根据WHERE条件设计分区字段
+5. **及时验证分区效果**：创建后立即检查分区是否正确
+
+#### 复杂迁移陷阱
+
+6. **多级时间分区不能直接迁移**：`year+month+day`要改为`days()`单一粒度
+7. **复合分区维度要精简**：过多维度会导致分区数量过多
+8. **分区演化策略要重建**：从自动管理改为手动调度管理
+9. **性能优化策略要调整**：Z-Order等高级优化需要重新设计
+10. **生命周期管理要补齐**：从自动清理改为脚本定期清理
+
+#### 创建验证陷阱
+
+11. **建议使用原生SQL创建分区表**：确保语法准确性
+12. **每次创建后必须验证**：执行完整的验证清单
+13. **性能测试要对比基准**：确保分区表确实比非分区表快
+14. **分区健康状态要监控**：定期检查分区大小和数量分布
+
+#### 高级语法陷阱
+
+15. **SHOW PARTITIONS不支持ORDER BY**：用WITH子查询实现排序
+16. **bucket函数参数要合理**：推荐使用1-1000范围的正整数
+17. **注意NULL值和特殊字符**：系统会创建对应的分区
+
+### 💡 **成功迁移的经验**
+
+#### 对于简单分区场景
+
+* **渐进式迁移**：先迁移小表验证，再迁移核心大表
+* **保留原有查询逻辑**：尽量让原有SQL无需大改即可工作
+* **性能基准对比**：迁移前后的查询性能对比验证
+* **完整验证流程**：严格按照验证清单执行
+
+#### 对于复杂分区场景
+
+* **分区策略重设计**：不要试图完全复制原有分区结构
+* **性能验证优先**：用代表性查询验证新分区策略的效果
+* **分阶段实施**：复杂迁移分为分析、重设计、测试、切换四个阶段
+* **回退方案准备**：确保迁移失败时能快速回退到原方案
+
+### 🚀 **特别提醒**
+
+**对于 Snowflake 等平台用户**：
+迁移到 Lakehouse 的挑战主要在于思维模式的调整。您需要从"较少关注分区"转变为"主动设计分区策略"。建议先在测试环境中体验分区对查询性能的影响，理解分区的价值，再开始设计生产环境的分区策略。
+
+**对于有复杂分区架构的用户**：
+不要试图在Lakehouse中完全复制原有的分区结构。Lakehouse的分区哲学是"简化而不失性能"。多级分区、复合分区等复杂设计在Lakehouse中往往可以用更简单的方案达到同样或更好的效果。
+
+**对于所有迁移用户**：
+分区表的创建验证是成功迁移的第一步，也是最关键的一步。建议使用原生SQL创建分区表，并严格执行验证清单。很多迁移问题都源于分区表没有正确创建，导致后续的性能优化无从谈起。
+
+记住：**Lakehouse 的分区不是负担，而是性能优化的利器**。正确使用分区，您将获得比原平台更好的查询性能和更灵活的数据管理能力。

+# OPTIMIZE 命令
+
+## 概述
+
+OPTIMIZE 是 ClickZetta Lakehouse 中用于表数据优化和压缩的核心操作命令。通过整合小文件、清理删除标记和重组数据布局，可以显著改善查询性能和存储效率。虽然 Lakehouse 后台会默认定期自动执行文件合并，但在频繁更新或需要精细控制合并频率的场景中，用户可以通过手动调用该命令来满足特定业务需求。该命令支持异步和同步两种执行模式，为不同场景提供灵活的优化方案。
+
+## 命令语法
+
+```sql
+OPTIMIZE table_name 
+[WHERE predicate]  -- 可选分区过滤条件
+[OPTIONS(...)]
+```
+
+1. table_name（必选）
+
+* 需要优化的目标表名称，格式为 `[schema_name.]table_name`
+
+2. WHERE predicate（可选）
+
+* 分区过滤条件，必须包含**完整的分区列匹配条件**。
+* 支持格式：`partition_column = 'value'` 或复合分区 `dt='2023-01-01' AND region='us'`。
+
+3. OPTIONS（可选）
+
+* Lakehouse 保留参数，用于控制优化行为。
+
+## 注意事项
+
+* 该功能只能在**通用型计算集群（GENERAL PURPOSE VIRTUAL CLUSTER）**中运行，在分析型集群中该功能不会生效。
+
+## 核心功能
+
+* **小文件合并**：将多个小数据文件整合为大文件，减少文件元数据开销。
+* **删除标记清理**：清理 UPDATE/DELETE 操作产生的删除标记，回收存储空间。
+* **数据重组**：重新整理数据布局，提升查询性能。
+
+## 执行模式
+
+### 1. 异步执行模式（默认）
+
+异步执行是 OPTIMIZE 的默认行为，操作在后台进行，不阻塞当前连接。
+
+#### 特点
+
+* **非阻塞**：立即返回 Job ID，操作在后台执行。
+
+#### 语法
+
+```sql
+-- 默认异步执行
+OPTIMIZE table_name;
+
+-- 显式指定异步执行
+OPTIMIZE table_name OPTIONS('cz.sql.optimize.table.async' = 'true');
+```
+
+### 2. 同步执行模式
+
+同步执行会阻塞当前连接，直到优化操作完全完成后才返回结果。
+
+#### 特点
+
+* **阻塞式**：操作完成才返回，期间连接被占用。
+* **实时反馈**：立即获得详细的执行统计和成功状态。
+* **适用场景**：开发测试、小表优化、验证优化效果。
+* **确定性**：确保操作完全完成。
+
+#### 语法
+
+```sql
+OPTIMIZE table_name OPTIONS('cz.sql.optimize.table.async' = 'false');
+```
+
+## 适用场景
+
+* 大量 UPDATE/DELETE 操作后的存储清理
+* 释放临时存储空间的定期维护任务
+* 优化表的总体存储布局

+# PUT 命令
+
+## 简介
+
+PUT 命令是 Lakehouse SQL 中的一个实用工具，用于将客户端主机的本地文件上传到 Lakehouse 数据湖的 Volume 对象中。通过该命令，用户可以轻松地将本地文件传输至云端，实现数据的快速迁移和同步。要执行 PUT 命令，您可以使用 [sqlline](connect-with-cli.md) 工具或 [数据库管理工具](eco_integration/dbeaver-lakehouse.md)。该命令暂不支持在 Studio 中运行。
+
+## 使用场景
+
+PUT 命令适用于以下场景：
+
+1. 将本地文件上传到数据湖 Volume 对象。
+2. 快速迁移和同步本地与云端数据。
+
+## 语法
+
+```
+PUT 'local_path' [ , 'local_path' [ , ... ] ] 
+    TO 
+    [ VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME ]
+    [ SUBDIRECTORY 'dir' | FILE 'filename' ]
+    [ option_key = option_value ] ..
+```
+
+## 参数说明
+
+* `local_path`：本地要上传文件的路径。**Linux / macOS**：路径以根目录 `/` 开始，或者使用 `'file:///'` 前缀表示本地路径。**Windows 系统**：如果目录路径和/或文件名包含特殊字符，则整个文件 URI 必须用单引号括起来。注意，在封闭的 URI 中，分隔符为正斜杠 (`/`)。
+* `VOLUME/TABLE VOLUME/USER VOLUME`：指将本地数据上传至外部 Volume、TABLE VOLUME 或 USER VOLUME。
+* `SUBDIRECTORY/FILE`：指定上传文件的目标路径，可以指定子目录（`SUBDIRECTORY`），也可以利用 FILE 参数对上传的文件进行重命名操作。
+
+## 示例
+
+1. 使用内部 Volume 上传文件到表中
+
+```
+--上传文件
+PUT '/Users/Downloads/data.csv' TO TABLE VOLUME my_table FILE 'data.csv';
+-- 查看文件
+SHOW TABLE VOLUME DIRECTORY my_table;
+--导入文件
+COPY INTO my_table FROM TABLE VOLUME my_table(id int, name string) USING csv  
+OPTIONS(
+        'header'='true',
+        'lineSep'='\n'
+)
+FILES ('data.csv')
+--删除volume中的文件，节省存储
+PURGE=TRUE;
+
+```
+
+2. 创建名为 `hz_image_volume` 的外部 Volume 对象，并上传文件 `'/Users/Downloads/cats_and_dogs.zip'`，将其重命名为 catsdogs.zip：
+
+   ```SQL
+   PUT '/Users/Downloads/cats_and_dogs.zip' to VOLUME hz_image_volume FILE 'catsdogs.zip'
+   ```
+
+3. 将本地数据上传至名为 `tbl_region` 的表的 Volume 空间：
+
+   ```SQL
+   PUT '/Users/Downloads/region.tbl' TO TABLE VOLUME tbl_region;
+   ```
+
+## 注意事项
+
+* PUT 命令不能通过 Studio SQL 任务节点执行。用户可以通过 Lakehouse SQLLine 客户端、JDBC 客户端或 SDK 来执行该命令。
+* 请确保上传的单个文件大小不超过 5 GB。
+* 在使用 PUT 命令时，请确保本地文件的路径和文件名正确无误，避免因路径错误导致上传失败。
+* 上传文件时，如果目标 Volume 对象中已存在同名文件，系统将自动覆盖原有文件。如有需要，请在上传前进行相应的备份操作。

+# 在云器 Lakehouse 的同一张表中进行向量和标量检索
+
+## 数据准备
+
+GitHub 提供 15 多种事件类型，包括新提交和分叉事件、打开新工单、评论和向项目添加成员等。这些事件会汇总到每小时存档中，您可以使用任何 HTTP 客户端从 <https://www.gharchive.org/> 上访问这些存档。
+
+* 通过 wget 从 <https://www.gharchive.org/> 将归档的 json.gz 文件下载到本地。本文下载了 2025-01-01 一天的 24 个文件。
+* 通过 Lakehouse 的 PUT 命令，将数据 PUT 到用户卷 (USER VOLUME) 上。
+* 通过 SQL 直接读取用户卷 (USER VOLUME) 目录里的文件，然后将 IssuesEvent 类型的事件写入 `github_event_issuesevent` 表中。
+* 将数据从 github\_event\_issuesevent 写入到目标表 github\_event\_issuesevent\_embedding 中。
+
+## 数据向量化
+
+云器 Lakehouse 的 `github_event_issuesevent_embedding` 表中保存了文本字段，需要对该文本字段进行向量化，并保存在同一张表的向量字段里，方便进行向量和标量的融合检索。
+
+该方案在同一张表、同一个 VCluster 中，同时支持文本数据、向量数据以及倒排索引和向量索引的存储。与传统方式相比，不再需要三套系统（数据仓库、文本检索数据库、向量数据库），最大程度地降低了数据副本数量，避免了数据在三套系统之间的同步。
+
+![](/.topwrite/assets/image_1768390312153.png)
+
+^
+^
+
+### 用到的云器 Lakehouse 关键特性
+
+* [向量存储](vector-type.md)：原生的Vector数据类型，在普通表里直接增加Vector类型的字段；
+* [向量索引](create-table-ddl.md)：对Vector类型的字段建立索引，加速向量检索的速度；
+* [倒排索引](create-table-ddl.md)：对文本字段建立倒排索引，加速文本检索的速度；
+* [bloom\_filter索引](create-table-ddl.md)：对ID字段建立索引，加速ID过滤；
+* [Zettapark](ZettaparkQuickStart.md)
+
+### 模型服务
+
+* xinference，本地部署xinference，提供embedding和rerank模型服务；
+* 本方案采用 1024 维的向量表示。
+
+### 测试数据集介绍
+
+* 数据来源是 GitHub 的 IssuesEvent 事件，全文检索字段为其中的 `issue_body`。
+* 向量字段存储的是 `issue_body` 对应的向量化数据。
+* 全表有 1.9 亿条记录。
+
+### 数据说明
+
+* 表名：`github_event_issuesevent_embedding`
+* 文本字段：`issue_body`，string 类型
+* 向量化字段：`issue_body_embedding`，vector(float,1024) 类型
+* 向量化方法：`issue_body_embedding` 的初始值为 NULL。调用 xinference/ollama 本地服务，用 bge-m3 模型对 `issue_body` 字段的文本进行向量化，然后保存到 `issue_body_embedding` 字段。
+
+### issue\_body\_embedding字段更新方法
+
+* **单条 Update 方法**
+  * 符合传统数据库开发者的习惯，数据更实时，达到秒级数据新鲜度。但是在大数据平台上用 SQL 进行频繁的 UPDATE，会带来明显的弊端：
+    * 带来大量的小文件需要及时进行合并，以优化性能。
+    * 需要一直启动 VCluster，造成计算成本高。
+
+* **批量 Merge Into 方法**
+  * 牺牲了数据新鲜度，从秒级到分钟级。
+  * 规避了小文件急剧增多的问题。
+  * 大幅降低了计算成本，每 5 分钟 MERGE INTO 一次，计算成本下降幅度可达 80%，大幅提升了数据向量化的性价比。这对大数据量的向量化非常重要。
+
+## 融合检索
+
+* 参考并已完成在云器 Lakehouse 的同一张表中进行向量和标量存储。

+Lakehouse 实现了 MySQL 客户端与服务端的通讯协议，因此可以使用 MySQL 驱动连接 Lakehouse。然而，Lakehouse 并未实现 MySQL 的语法和数据类型。您可以通过 MySQL 客户端连接到 Lakehouse，但执行的 SQL 语句应使用 Lakehouse 语法，而非 MySQL 语法。例如，`mysqldump` 命令在 Lakehouse 中不可用。本文使用 PowerBI 中的 MySQL 驱动连接 Lakehouse，快速了解如何连接 Lakehouse。我们使用财务示例数据集。
+
+## 准备工作
+
+* 目前需要重置密码，即使是新建的账号也需要重置密码。这是因为 MySQL 5.x 版本使用的是 `mysql_native_password` 密钥，而 Lakehouse 需要保存 MySQL 的加密算法。目前，只有在修改密码时，Lakehouse 才会保存 MySQL 密钥的加密算法。您可以修改密码时保持和之前一样这样可以避免影响别的任务连接
+
+* 给用户设置计算集群，由于 MySQL 协议中没有传入设置集群的方式，用户可以使用 SQL 命令为用户添加一个默认计算集群。这样在 MySQL 连接时就会使用该集群。需要注意的是，BI场景对分析性能往往有要求，建议为BI工具连接用户选择合适规格的分析型计算集群以提供最佳的查询性能。
+
+  ```SQL
+   ALTER USER user_name SET DEFAULT_VCLUSTER = default_ap;
+    
+   -- 查看集群设置是否生效
+   SHOW USERS;
+  ```
+
+* 准备用户名。 MySQL 协议连接地址时只能传入一个 URL，无法拼接 Lakehouse 的 instance name 和 workspace name，因此需要将 instance name 和 workspace name 拼接到用户名中。
+
+  *   用户名格式要求如下：
+
+  * ```Plain
+    登录的账号名称@instance_name.workspace_name
+    ```
+
+  * **instance\_name 获取**：在 工作空间页面 中获取 JDBC 连接串。例如，在 `jdbc:clickzetta://``jnsxwfyr.api.clickzetta.com/quick_start?virtualCluster=default` 中，`jnsxwfyr` 为 instance\_name。
+
+    * ![](.topwrite/assets/image_1723468458225.png)
+
+  * **workspace\_name 获取**：工作空间的名称。
+
+* 在 Lakehouse 中创建 schema 和 table，并上传数据。
+
+```Plain
+create schema sales;
+use sales;
+create table salesdata (
+    segment varchar(255),
+    country varchar(255),
+    product varchar(255),

+# 使用Python任务将gharchive网站数据同步到对象存储

+
+## 运行测试
+
+点击“运行”对代码进行测试，查看运行结果是否符合预期。
+
+## 调度设置与任务发布
+
+由于 gharchive 网站每小时新生成一个文件，因此将调度周期设置为 1 小时即可。
+
+![](.topwrite/assets/image_1718680082074.png =683)
+
+然后点击“提交”完成发布。这样，Python 任务就可以通过周期调度，完成将 gharchive 文件同步到云对象存储 OSS 的工作。
+
+## 补数实现全量同步
+
+周期任务从指定的时间开始周期性执行，从而获取数据。为了获取此时间点之前的全量数据，可以直接使用同样的代码和任务，执行“补数”操作，批量同步周期任务第一个调度周期之前的所有数据，从而实现全量同步。这种方式非常方便，并且通过同一套代码保证了逻辑的一致性。
+点击“运维”，进入周期任务的运维页面，然后点击“补数”。
+gharchive 上的文件从 2012-02-12 日开始生成，因此将补数任务的开始时间设置为 2012-02-12 00:00:00。
+该任务的周期调度是从 2024-06-18 日的 11 点开始的，因此将补数任务的结束时间设置为 2024-06-18 11:00:00。
+
+![](.topwrite/assets/image_1718680764715.png)
+
+预览补数任务生成的实例，共将产生 108251 个任务实例。这意味着上述时间段总共有 108251 个小时，也意味着本次补数操作将从 gharchive 网站同步 108251 个文件到云对象存储上。
+
+![](.topwrite/assets/image_1718680957720.png =419)
+
+## 任务编排
+
+在后续任务开发中，可以通过将本任务设置为依赖任务，实现工作流编排。

+# 利用 External Catalog 访问 Snowflake Open Catalog 中的 Iceberg 表
+
+## **概述**
+
+Lakehouse 支持通过 Catalog Integration 功能连接第三方的 Iceberg REST API，实现与外部数据目录的无缝集成。本文档介绍如何连接和使用 Snowflake 的 Open Catalog 功能。
+
+**功能特性**：
+
+* **统一数据访问**：通过统一的接口访问 Snowflake Open Catalog 中的 Iceberg 表
+* **实时数据同步**：直接读取 Snowflake 中的最新数据，无需数据复制
+* **元数据映射**：自动映射 Snowflake 中的表结构和元数据信息
+* **OAuth 认证**：支持安全的 OAuth 2.0 认证机制
+
+## **环境准备**
+
+Snowflake Open Catalog 提供了两种类型的目录：
+
+**Internal Catalog**：
+
+* **功能特性**：Lakehouse 支持完整的读写操作
+* **数据管理**：支持表结构变更、数据插入、更新、删除等全生命周期操作
+
+**External Catalog**：
+
+* **功能特性**：Lakehouse 仅支持只读操作
+* **数据访问**：支持复杂查询、联表分析，但不支持数据修改操作
+
+在 Snowflake 中准备 Iceberg 表，并注册到 Snowflake Open Catalog 中，请参考 [Snowflake 官方文档](https://docs.snowflake.com/en/user-guide/tables-iceberg-open-catalog-sync)
+
+实现效果：在 Snowflake Open Catalog 中，注册了一张位于 Snowflake 引擎中的表：
+
+* Database 名称： ICEBERG\_TABLES\_DB\_FLATTEN
+* Schema 名称：ICEBERG\_SCHEMA
+* Iceberg 表名：czcustomer （要求小写。Snowflake 的建表 DDL 中，用双引号避免表名自动转成大写）
+
+> 注意：在 Snowflake 引擎中创建 Database 时，需加入 `CATALOG_SYNC_NAMESPACE_MODE` 和 `CATALOG_SYNC_NAMESPACE_FLATTEN_DELIMITER` 两个参数以调整 Catalog 层级。如下配置后，在 Snowflake Open Catalog 中，Database 与 Schema 将合并成一个层级："`ICEBERG_TABLES_DB_FLATTEN_ICEBERG_SCHEMA"`
+>
+> ```
+> CREATE OR REPLACE DATABASE iceberg_tables_db_flatten
+> CATALOG_SYNC_NAMESPACE_MODE = 'FLATTEN'
+> CATALOG_SYNC_NAMESPACE_FLATTEN_DELIMITER = '_';
+> ```
+
+![](.topwrite/assets/20250901-112722.jpeg)
+
+## **配置步骤**
+
+### 步骤 1：创建 Catalog Connection
+
+使用以下 SQL 语句创建与 Snowflake Open Catalog 的连接：
+
+```
+CREATE CATALOG CONNECTION snow_opencatalog 
+    TYPE ICEBERG_REST 
+    URI='https://lhnrdre-derekmeng.snowflakecomputing.com/polaris/api/catalog'

+| NAMESPACE             | Snowflake Open Catalog 中的第二个层级  | `ICEBERG_TABLES_DB_FLATTEN_ICEBERG_SCHEMA`                   |
+| WAREHOUSE             | Snowflake Open Catalog 的 Catalog 名称 | `singdata`                                                   |
+
+### 步骤 2：创建外部表
+
+创建外部表来映射 Snowflake Open Catalog 中的表：
+
+```SQL
+-- 创建外表，映射 Snowflake Open Catalog 中的表（表名需一致）
+CREATE EXTERNAL TABLE IF NOT EXISTS `czcustomer`
+USING ICEBERG 
+CONNECTION snow_opencatalog;
+```
+
+> **注意**：外部表名必须与 Snowflake 中的表名完全一致。
+
+### 步骤 3：验证和查询
+
+验证表结构并查询数据：
+
+```SQL
+-- 查看表结构
+DESC EXTENDED `czcustomer`;
+
+-- 查询数据
+SELECT * FROM `czcustomer` LIMIT 10;
+```
+
+![](.topwrite/assets/opencatalog_3.jpeg)
+
+## 使用限制
+
+* 连接基于 S3 的 Snowflake 托管的 Iceberg 表时，不支持写入和更新操作
+* 外部表名必须与 Snowflake 中的源表名完全匹配
+* 暂时仅支持小写表名
+* 不支持表名转换
+* 在目标 Catalog 服务侧，需要开启 Credential Vending 配置

+# 刷新物化视图
+
+## 功能描述
+
+在数据库中，物化视图是一种特殊的视图，它将查询结果以表的形式存储在数据库中。当物化视图所依赖的表数据发生变化（如插入、覆写、更新、删除等操作）时，物化视图会自动失效，无法用于查询和改写。为了确保物化视图的数据保持最新，需要手动刷新物化视图。
+
+有关更多详细信息，请参阅[物化视图](<MATERIALIZEDVIEW.md>)。
+
+## 语法
+
+```SQL
+REFRESH MATERIALIZED VIEW mv_name;
+```
+
+## 参数说明
+
+- **mv_name**：指定要刷新的物化视图名称。
+
+## 使用示例
+
+1. 假设我们有一个物化视图 my_mv，它是基于员工表（employees）和部门表（departments）的关联查询结果创建的。现在我们需要刷新 my_mv，以确保它包含最新的员工和部门信息。可以使用以下 SQL 语句：
+
+   ```SQL
+   REFRESH MATERIALIZED VIEW my_mv;
+   ```
+
+2. 另一个例子，如果我们有一个物化视图 sales_summary，它根据销售数据表（sales_data）生成销售摘要。当销售数据表发生更改时，我们需要刷新 sales_summary 以反映最新的销售情况。可以使用以下 SQL 语句：
+
+   ```SQL
+   REFRESH MATERIALIZED VIEW sales_summary;
+   ```
+
+## 注意事项
+
+1. 在执行刷新物化视图操作时，确保物化视图所依赖的表数据已经更新。
+2. 刷新物化视图可能会消耗较多的系统资源和时间，尤其是在处理大量数据时。因此，建议在系统负载较低时执行此操作，以免影响其他数据库操作。
+3. 根据物化视图的复杂程度和依赖关系，刷新操作可能会触发重新计算物化视图的查询结果。在某些情况下，可以考虑使用增量刷新（如支持的数据库系统），以提高刷新效率。

+
+## 新功能特性
+
+### 【预览】支持创建倒排索引加速检索分析
+
+本次发布新增倒排索引支持。倒排索引对文本进行分词处理，同时保存分词与记录之间映射关系。当用户根据关键词进行文本检索时，查询引擎将通过索引数据快速找到匹配的数据记录，显著加速文本检索性能。
+
+本次发布支持对字符串类型字段创建倒排索引，并提供了一组内建函数用于表达文本匹配条件及规则。
+
+更多信息，请查看[倒排索引](inverted-index.md)文档。
+
+### 数据湖存储Volume新增内部Volume对象类型
+
+在外部Volume基础上，新增表Volume和用户Volume两种内部Volume类型。表Volume和用户Volume由系统预定义默认创建，内部Volume的数据保存在Lakehouse托管存储区域，无需与外部存储服务打通即可快速管理和使用非结构化数据。内部Volume能够简化UDF资源文件管理、数据导入/导出文件临时存储以及开发测试等场景的文件数据管理和使用。
+
+更多信息，请查看[Volume](datalake_volume.md)文档。
+
+### 【预览】External Function 支持UDAF和UDTF
+
+External Function先前已经提供了对UDF（即：scalar UDF）的支持，本次升级扩展支持UDFA和UDTF自定义函数。您可以使用Hive UDF API开发UDAF以及UDTF。
+
+文档更新，增加了UDF、UDAF、UDTF的开发样例说明。
+
+更多信息，请查看[Java UDF开发指南](ExternalFunctionDevGuideJava.md)文档。
+
+### 外部表：支持DELTA LAKE外部表
+
+新增外部表对象类型，通过外部表无需将数据导入，可直接访问外部存储中的数据。本次发布支持创建和使用DELTA LAKE格式的外部表。创建外部表时，支持使用CONNECTION对象定义外部表的服务连接信息。
+
+更多信息，请查看[外部表](external-table-guide.md)文档。
+
+### 【 预览】PIPE管道任务支持Kafka数据实时导入
+
+新增PIPE对象类型，通过PIPE管道可以创建从外部流式数据源持续导入数据到目标表的实时任务。无需第三方ETL工具或引擎，PIPE任务由SQL引擎直接实现流式数据源的读取和写入，减少了不必要的中间暂存、格式转换的计算开销，能够极大提升实时导入环节，提高导入吞吐并降低导入成本。
+
+更多信息，请查看[PIPE管道](pipe-summary.md)文档。
+
+## 数据湖更新
+
+### 服务连接对象支持GCS对象存储
+
+通过STORAGE CONNECTION可以管理对象存储服务的连接及身份认证信息，当前支持阿里云OSS、腾讯云COS基础上，增加对谷歌云GCS对象存储服务的支持。使用STORAGE CONNECTION可实现存储服务连接的权限控制，不同任务和用户可复用已定义的连接对象。
+
+更多信息，请查看[CONNECTION](CREATECONNECTION.md)文档。
+
+### External Schema增加访问HMS管理的GCS数据
+
+External Schema通过映射外部元数据服务下的Schema（或者两层结构下的database），实现对外部Schema下数据对象的外表访问。本次升级，External Schema增加对HMS存储在谷歌云GCS数据的访问能力。
+
+更多信息，请查看[外部Schema](EXTERNALSCHMEA.md)文档。
+
+## 实时增量计算
+
+### 动态表：查看动态表刷新历史
+
+新增SHOW DYNAMIC TABLE REFRESH HISTORY命令，支持查看动态表刷新历史。刷新历史中可观察到每次刷新作业的执行状态、刷新作业运行时长、增量或全量刷新类型、当次刷新任务处理的记录数量（包括写入、删除类型）等信息。通过刷新历史可以实现动态表刷新运行（特别是周期性运行）的监控，根据指标情况调整调度周期或者资源大小以满足业务SLA要求。
+
+文档更新：增加[动态表使用最佳实践](<dynamic_table_summary.md>)介绍。
+
+更多信息，请查看[动态表](dynamictable.md)文档。
+
+### 【预览】动态表：支持对使用自定义函数的动态表进行增量处理
+
+动态表的定义，支持使用通过External Function创建的自定义函数（包括UDF、UDAF、UDTF）。在使用了自定义函数定义的动态表执行刷新时，系统自动将进行增量处理优化，进一步扩展了动态表增量处理的适用范围。
+
+预览期间非默认打开，该功能需要通过特定参数启用。
+
+更多信息，请查看[动态表中使用UDF](using-udf-in-dynamic-table.md)文档。
+
+## Information Schema更新
+
+### Information Schema新增Volume和Connection对象视图
+
+新增数据湖存储*VOLUMES视图*、*CONNECTIONS视图*，您可以通过查询INFORMATION\_SCHEMA下的对应视图获取数据湖存储Volume和外部服务连接Connection对象信息。
+
+更多信息，请查看[INFORMATION\_SCHEMA](instance-informaiton-schema.md)文档。
+
+## SQL 能力更新
+
+### 支持使用同义词SYNONYM作为别名访问已有对象
+
+通过创建SYNONYM同义词可以对已有数据对象的位置及名称进行引用和包装，可以简化数据对象的访问或者提升数据对象访问的安全性。
+
+更多信息，请查看[同义词](synonym.md)文档。
+
+### 支持TIMESTAMP\_NTZ类型
+
+时间数据类型在TIMESTAMP\_LTZ类型基础上，增加TIMESTAMP\_NTZ类型。TIMESTAMP\_NTZ类型即timestamp without time zone，用于存储不包含时区信息的日期和时间值，不考虑时区的变化。相较于其他带有时区的时间戳类型（TIMESTAMP\_LTZ），TIMESTAMP\_NTZ无需进行时区转换，能够极大简化在多时区环境或跨系统传输数据场景下的时间戳类型数据的处理逻辑。
+
+更多信息，请查看[TIMESTAMP\_NTZ 类型](data-types-timestamp-ntz.md)文档。
+
+### 【预览】使用IDENTITY设置字段自增属性
+
+在创建表时，支持对使用IDENTITY列属性指定自增长列。
+
+更多信息，请查看[IDENTITY自增列](IDENTITY-Column.md)文档。
+
+### 内建函数
+
+本次发布新增以下内建函数：
+
+| **函数名称**              | **说明**             |
+| --------------------- | ------------------ |

+### 兼容性扩展：新增MAX\_PT函数，支持查看最新分区表最大分区
+
+使用max\_pt可返回分区表最大的一级分区的值，对于存量任务使用该函数的作业增强了语法兼容性。
+
+### 内建函数
+
+本次发布新增以下内建函数：
+
+| **函数名称**                   | **说明**                                        |
+| -------------------------- | --------------------------------------------- |
+| CHARACTER\_LENGTH          | 返回字符串中字符的数量                                   |
+| CHAR\_LENGTH               | 等效于CHARACTER\_LENGTH，用于返回字符串中字符的数量。           |
+| LENGTHB                    | 返回字符串参数的字节长度。                                 |
+| PERCENTILE\_APPROX         | 用于计算近似百分位数。它返回一个表中指定列值的近似百分位数。                |
+| PERCENT\_RANK              | 用于计算百分位排名。它返回一个值在一组值中的相对位置。                   |
+| FORMAT\_STRING             | 用于格式化字符串。它基于 `printf` 样式的格式字符串生成格式化后的字符串。     |
+| REGEXP\_EXTRACT\_ALL       | 用于从字符串中提取与正则表达式匹配的所有子串。                       |
+| STR\_TO\_DATE\_MYSQL       | 用于将字符串转换为日期，其实现与 MySQL 中的 `STR_TO_DATE` 函数兼容。 |
+| MAX\_PT                    | 用于获取分区表中最大分区的值。                               |
+| IS\_IP\_ADDRESS\_IN\_RANGE | 用于判断一个 IP 地址是否包含在某个网络范围内。                     |

+* 作业历史 & 作业详情：修正部分作业（如 desc, show 等命令）在作业历史（Job History）列表中不能显示作业耗时信息的问题。
+
+## 行为变更
+
+* 虚拟集群管理（Virtual Cluster）Preload Cache：设置了Preload Cache的集群在启动时，原有行为是默认对配置Preload的表进行主动全量Cache。当前行为变更为：启动集群后，对配置Preload的表进行增量Cache。即：默认仅对新变化的数据做主动Cache。
+* 动态表自动刷新：在CREATE DYNAMIC TABLE的DDL定义中可设置系统自动刷新的时间间隔以及刷新作业运行的计算资源。原有行为是通过动态表在PROPERTIES 中添加refresh\_vc参数进行设置，例如设置PROPERTIES('refresh\_vc'='vcluster\_name)后，动态表自动刷新任务将使用vcluster\_name集群执行任务。当前行为变更为：使用REFRESH INTERVAL \[interval\_time] VCLUSTER \<virtual\_cluster\_name>语法设置自动刷新作业使用的集群名称。原有的PROPERTIES参数行为将继续保留和兼容。

+* 支持PURGE=TRUE参数:当设置PURGE=TRUE时，在加载过程中删除已成功加载的文件。
+* 支持`OVERWRITE`参数：使用`OVERWRITE`参数时，现有表数据将被清空，然后导入新的数据。`OVERWRITE`具有原子性，只有在导入成功后才会清空表数据并写入新数据。
+
+### Pipe功能增强
+
+* **新增模式**：即使在没有对象存储消息服务通知的情况下，Pipe也能检测到新增文件并进行同步。
+* **导入历史记录**：Pipe读取对象存储的功能还支持`load_history`函数，用于记录成功导入的文件。
+* **Pipe过滤**：新增了Pipe过滤功能，用户可以通过`query tag`来过滤Pipe作业历史。
+
+## 虚拟计算集群
+
+* **GP型动态扩容能力**：支持在任务出现资源等待和排队情况时进行动态扩容，解决了无法纵向扩容（增加单集群实例CPU和内存数）的限制。这有助于应对GP VC上负载波动大的情况，避免按照峰值购买VC资源的不经济性，同时满足负载波峰的需求。
+* **VC SIZE设置**：支持设置CRU数值大小。CRU是计算资源的计量单位，1 CRU相当于云厂商云服务器资源8核运行1小时所提供的算力。
+
+## 增量计算更新
+
+### TABLE\_CHANGES函数增强
+
+* 默认行为：TABLE\_CHANGES函数会返回在指定偏移量之后和当前时间之前提交的事务所造成的变化，但不会返回具体的操作明细。例如，如果在两个点位之间先发生了插入（insert），然后发生了删除（delete），默认情况下返回结果为空。
+* 增强功能：通过增加`map('TABLE_STREAM_MODE', 'ORIGINAL')`参数，TABLE\_CHANGES函数会返回两个点位之间的所有变化明细。例如，上述案例中的插入和删除操作都会被返回。
+
+## SQL查询优化
+
+### 小文件优化
+
+* **自动合并小文件**：在执行写入操作（如INSERT、UPDATE、DELETE、COPY语句）前，通过设置set cz.sql.compaction.after.commit=true;，可以自动触发小文件合并。这有助于提高后续查询的效率，因为可以避免读取大量小文件。请注意，启用此设置后，INSERT、UPDATE、DELETE、COPY语句的执行时间可能会增加。
+
+### Preload Cache
+
+* AP型计算集群（ANALYTICS PURPOSE VIRTUAL CLUSTER）支持查看缓存状态
+
+## SQL 能力更新
+
+### 创建表时支持指定默认值和生成列
+
+* 在本SQL引擎中，创建内部表时，您现在可以为列指定默认值（defalult value）或定义生成列(generated column)，以自动化数据填充和处理。这使得数据管理更加高效，特别是在处理分区表时。目前不支持实时写入接口写入，如果实时接口没指定该值则会为null不会自动填充该值。
+
+### 支持向量索引
+
+采用 HNSW（Hierarchical Navigable Small World）算法构建向量索引。用来加速向量检索。
+
+### 数据类型
+
+Array类型:可以使用常量格式如 `[1, 2, 3]` 来定义数组,当字符为上述格式时，会被识别为数组类型。
+
+Vector类型：Lakehouse 提供了 VECTOR 类型来存储这些转化后的向量，构建索引可以提高向量搜索性能
+
+### 函数支持
+
+| 函数名称              | 功能                                |
+| ----------------- | --------------------------------- |
+| median            | 根据组的值计算出的中值                       |
+| group\_concat     | 将组中的值连接成一个字符串。                    |
+| multiif           | 用于在查询中更紧凑地编写 CASE 运算符.            |
+| ceiling           | 返回大于或等于指定数的最小整数。等同于ceil           |
+| log               | 计算指定数的对数。                         |
+| current\_timezone | 返回当前时区。                           |
+| power             | 计算指定数的幂。                          |
+| if                | 支持两个参数，如果不写第三个参数默认是NULL           |
+| nvl2              | 如果第一个参数不为NULL，则返回第二个参数，否则返回第三个参数。 |
+
+## 行为变更
+
+### 数据类型
+
+varchar数据类型变化:varchar长度变更由65535变为1048576
+
+### SDK接口
+
+在 JDBC 2.0.0 之后的版本中，本地 COPY 命令已被弃用。我们建议您使用 PUT 方法将数据上传到 volume 中，然后使用服务器端的 COPY 命令进行导入。

+# 2025年03月03日 — 1.0 Lakehouse Platform 产品更新发布说明
+
+本次发布，我们引入了一系列新功能、增强特性以及修复项。这些更新将分阶段逐步推送至以下区域，预计在发布日起一周至两周内完成。具体时间依据您所在的区域而定。
+
+* 阿里云上海区
+* 腾讯云上海区
+* 腾讯云北京区
+* 腾讯云广州区
+* 亚马逊北京区
+* 国际站-阿里云-新加坡区
+* 国际站-AWS-新加坡区
+
+## 新功能特性
+
+### 联邦查询更新【预览发布】
+
+* **架构扩展**：云器Lakehouse支持使用External Schema在Catalog级别映射和镜像外部数据源支持查询 Hive（之前只支持 Hive 对象存储架构，本期支持 Hive HDFS 架构）。参考[EXTERNAL SCHEMA](EXTERNALSCHMEA.md)
+* **增强Delta Lake格式读取**：创建外部表Delta Lake格式自动Schema推断——创建外部表时无需手动声明字段信息，系统自动解析元数据。参考[Delta Lake 外部表](delta-lake.md)
+
+## 导入导出更新
+
+### COPY命令增强
+
+支持双字符CSV分隔符（如 `||`），突破原有单字符限制，提升复杂数据兼容性。参考[COPY INTO导入](copy-into-table.md)
+
+### Pipe功能增强
+
+1. 支持[Kafka Table Stream](pipe-kafka-table-stream.md)直连导入，通过 Table Stream 您可以实现 Exactly Once，同时支持将连接信息存储在 Connection 中
+
+2. [Pipe SQL命令优化](pipe-syntax.md)
+
+   * 支持通过`SHOW CREATE PIPE pipe_name`获取Pipe的DDL语句
+   * Pipe DESC 结果输出优化。DESC PIPE pipe_name 显示结果字段，Pipe 任务的输入对象名称和输出对象名称，增加 Kafka 点位消费信息
+   * 支持Alter命令修改Pipe导入参数如修改计算集群
+
+3. Pipe导入对象存储数据。支持过滤`.`开头和 `_temporary` 开头的文件或者目录文件。参数`IGNORE_TMP_FILE=FALSE|TRUE`。例如：
+
+   ```
+   s3://my_bucket/a/b/.SUCCESS
+   oss://my_bucket/a/b/_temporary
+   oss://my_bucket/a/b/_temporary_123/
+   ```
+
+## 计算集群
+
+**精细化资源控制**
+
+新增[GP型计算集群单作业资源占比配置](alter-vcluster.md)，控制单作业最大资源占比 10%。避免大查询引发的资源抢占，提升集群稳定性：
+
+```
+ALTER VCLUSTER sample_vc SET QUERY_RESOURCE_LIMIT_RATIO='0.1'; 
+```
+
+## SQL语法
+
+1. 支持创建[SQL FUNCTION](create-sql-function.md)。通过这一功能，用户能够利用SQL DDL（数据定义语言）语句来定义自定义的SQL函数，从而增强数据处理和分析的灵活性。
+2. Lakehouse 正式推出[列级安全（Column-level Security）功能](dynamic-mask.md)，支持通过动态脱敏（Dynamic Data Masking）实现对敏感数据的细粒度控制。此功能允许管理员根据用户角色或属性，动态隐藏、部分显示或替换列中的敏感信息（如身份证号、信用卡号等），从而有效保护数据隐私。用户可以通过以下 SQL 语句实现动态脱敏：
+
+```SQL
+ALTER TABLE <table_name> MODIFY COLUMN <column_name> SET MASKING POLICY <policy_name>;
+```
+
+通过定义脱敏策略并将其应用于表的列，在查询运行时，屏蔽策略将应用于该列出现的每个位置，根据屏蔽策略条件、SQL 执行上下文角色或者用户来进行脱敏。
+
+3. Lakehouse 数据存储优化功能。通过 [OPTIMIZE 命令](small_file_optimization.md)的高级参数，用户可以进行小文件合并
+4. DML增强：`UPDATE` 支持 `ORDER BY ... LIMIT` 语法
+5. 【预览发布】[多方言兼容](sql-parmaters.md)：通过SQLGlot集成支持PostgreSQL/MySQL/Hive/Presto等方言的部分语法
+
+## UDF功能
+
+新增 `cz.sql.remote.udf.lookup.policy` 配置参数,支持动态切换 UDF 与内置函数的解析优先级
+
+```SQL
+-- 策略1：优先调用内置函数（兼容传统OLAP系统行为）
+SET cz.sql.remote.udf.lookup.policy = builtin_first;
+
+-- 策略2：优先调用UDF（适配MC/Spark作业场景）
+SET cz.sql.remote.udf.lookup.policy = udf_first;
+
+-- 默认策略：强制要求UDF带Schema前缀（保持历史兼容性）
+SET cz.sql.remote.udf.lookup.policy = schema_only; 
+```
+
+## 权限管理【预览发布】
+
+[新增Instance级别角色与跨空间授权能力](CREATEROLE.md):支持在实例（Instance）粒度创建角色并授予全局权限，实现跨空间（Workspace）的统一权限管控，满足多团队协作场景下的精细化访问控制需求。
+

+# 2025年04月22日 — 1.1 Lakehouse Platform 产品更新发布说明
+
+本次发布（Release 2025.04.22），我们引入了一系列新功能、增强特性以及修复项。这些更新将分阶段逐步推送至以下区域，预计在发布日起一周至两周内完成。具体时间依据您所在的区域而定。
+
+**国内区域**
+
+* 阿里云（上海）
+* 腾讯云（上海/北京/广州）
+* 亚马逊云科技（北京）
+
+**国际区域**
+
+* 阿里云（新加坡）
+* AWS（新加坡）
+
+# 新功能特性
+
+## 联邦查询增强
+
+* 【预览发布】**ORC格式支持**：External Catalog/External Schema新增对HMS的ORC文件格式表的读写能力
+
+## 数据导入导出优化
+
+#### 导入命令COPY INTO \<table>
+
+* 换行符智能识别：同时支持 `\r\n` 与 `\n` 格式
+* [on\_error=abort|continue](copy-into-table.md) 策略：
+  * `continue` 模式：跳过压缩格式错误继续执行
+  * `abort` 模式：遇错立即终止
+  * 执行后可展示导入文件列表
+
+#### 导出命令COPY INTO \<location>
+
+* `writebom=true` 参数：导出 CSV 的时候带上 BOM 头，解决 Excel 打开时的中文乱码问题，提高跨平台兼容性
+* `overwrite=true` 参数：清空目标文件夹后导入（含子目录）
+
+### Pipe功能增强
+
+* Pipe 文件持续导入：支持通过 `on_error=continue` 参数忽略错误（跳过压缩格式错误继续执行）继续执行
+
+## SQL功能
+
+* **INTERVAL类型扩展**：允许 \`INTERVAL expr unit\` 中的expr写表达式。如`interval 1+2 year`
+* **元数据展示**：`DESC`/`SHOW` 命令新增显示share类型的schema信息
+* **数据采样**: 新增 [TABLESAMPLE ](tablesample.md)采样语法支持高效数据抽样分析
+* **向量检索**：支持 ef 参数，执行查询前配置ef 参数：`set cz.vector.index.search.ef=64;`
+* **倒排索引**:创建倒排索引时，支持 `'mode' = 'max_word' `参数，以支持更细粒度分词模式：
+  `properties ('analyzer' = 'chinese', 'mode' = 'max_word');`
+
+## 函数
+
+### 内建函数
+
+* **GET\_JSON\_OBJECT性能提升**：优化了GET\_JSON\_OBJECT的实现，提升了JSON解析效率。
+
+### 自定义SQL函数
+
+**SQL 函数增强**：支持[创建 RETURNS TABLE 类型的用户定义SQL函数](create-sql-function.md)
+
+### UDF
+
+External Function支持通过VOLUME地址引用资源文件
+
+* **User Volume 格式地址**:`volume:user://~/upper.jar`
+  * `user` 表示使用 User Volume 协议。
+  * `~` 表示当前用户，为固定值。
+  * `upper.jar` 表示目标文件名。
+* **Table Volume 格式地址**`volume:table://table_name/upper.jar`

+# 重新定义ELT：通过云器Lakehouse实现ELT新方式
+
+## 问题与挑战
+
+在很多数据项目中，特别是与ML、AI关系比较紧密的数据项目中，往往需要通过Python、SQL混合的方式进行开发实现，比如通过Jupyter Notebook进行Python代码的开发，用DBeaver、VS Code等数据管理和开发工具进行SQL代码的开发。在这种方案中，经常容易发生版本管理缺失、缺少统一的调度服务等问题，从而使开发和运维变得复杂且困难。
+
+随着现代化数据栈的发展，Metabase、MindsDB等新一代BI、AI分析产品也得到飞速发展。数据平台如何紧密融入现代化数据栈，提供完整的解决方案，也变得至关重要。
+
+对于日趋增多的半结构化数据以及向量数据（如CSV、JSON），如果依赖客户端解析会严重影响整体处理速度，这就要求数据平台能够同时高性能地处理表格中的结构化数据以及JSON数据、向量数据。比如GH Archive提供的GitHub每小时的事件归档数据集，就是以JSON格式提供的。
+
+在数据清洗和转换的数据工程工作中，往往需要开发很多中间表才能得到最终的目标表。如何提高这一环节的效率，也成为提升数据工程师生产力的一个重要课题。
+
+## 通过云器Lakehouse实现ELT的新方式
+
+今天笔者尝试使用云器Lakehouse，从以下三个方面寻找以上问题的新解法。
+
+![](.topwrite/assets/image_1734348544459.png)
+
+### 统一数据任务开发和调度
+
+通过云器Lakehouse简化数据任务开发和运维环境，实现统一的任务版本管理：
+
+* [Python任务开发](Python_Task.md)：从Jupyter Notebook开发到云器Lakehouse Studio的Python任务开发。
+
+* [SQL任务开发](taskdevelop.md)：从DBV SQL任务开发到云器Lakehouse Studio的SQL任务开发。
+
+* [ML/AI任务开发](jdbc_task.md)：从MindsDB Web IDE到云器Lakehouse Studio的JDBC任务开发。
+
+* [任务调度和运维](task-instance-maintenance.md)：从Airflow到云器Lakehouse Studio任务调度和运维。
+
+  ![](.topwrite/assets/image_1734348698701.png =460)
+
+### [多数据类型支持](data-type.md)
+
+云器Lakehouse支持以下数据类型的高效存储和访问：
+
+* Table里常见的基本数据类型
+
+* Table里常见的复杂数据类型
+
+* JSON
+
+* Vector
+
+* 文本倒排索引
+
+  ![](.topwrite/assets/image_1734348746004.png =380)
+
+### [动态表Dynamic Table](dynamic-table.md)
+
+云器提供的动态表（Dynamic Table），具备以下典型特性：
+
+* 声明性编程：用声明性 SQL 定义管道结果，不用再考虑中间表逻辑，降低复杂度。
+* 透明编排：通过将动态表、普通表链接在一起，管理刷新编排调度。
+* 增量处理：适合增量工作负载，动态表性能优。
+* 轻松切换：单命令实现批处理到流式处理过渡，平衡成本与新鲜度。
+* 可观测：动态表可通过云器Lakehouse Web控制台Studio管理，提高可观测性。

+
+## 应用案例：GHArchive数据ELT流程实现
+
+![](.topwrite/assets/image_1734348838607.png)
+
+### 数据源介绍：[GHArchive](http://www.gharchive.org/)
+
+全球范围内的开源开发者正在从事数以百万计的项目，涵盖诸如编写代码和文档、修复错误以及提交等工作。[GH Archive](http://www.gharchive.org/) 这一项目会对公共GitHub的事件数据予以记录，该项目提供了自2011年2月12日起始，长达13年多的GitHub事件数据存档，并使数据更易于访问，为进一步分析创造便利条件。
+
+GitHub有15种以上事件类型，例如新提交（Push）、分叉仓库（Fork）、新建Issue、评论以及为项目添加成员等。这些事件会汇总到每小时的归档文件里，用任何HTTP客户端都能访问这些归档文件，每个归档文件里都以JSON编码GitHub API报告的事件。用户可以下载原始数据自行处理，例如编写自定义聚合脚本、将其导入数据库等。
+
+GitHub 的事件数据示例如下：
+
+```
+{"id":"44809399421","type":"CreateEvent","actor":{"id":81469924,"login":"temperature48","display_login":"temperature48","gravatar_id":"","url":"https://api.github.com/users/temperature48","avatar_url":"https://avatars.githubusercontent.com/u/81469924?"},"repo":{"id":903968841,"name":"temperature48/SmashVat","url":"https://api.github.com/repos/temperature48/SmashVat"},"payload":{"ref":null,"ref_type":"repository","master_branch":"master","description":null,"pusher_type":"user"},"public":true,"created_at":"2024-12-16T02:00:00Z"}
+```
+
+^
+
+### 开发任务：数据抽取（**E**xtract）
+
+接下来我们通过云器Lakehouse Studio开发一个Python任务，将数据从GH Archive网站抽取到数据湖存储（本方案采用阿里云OSS）中。
+
+![](.topwrite/assets/image_1734348912514.png)
+
+^
+
+```py
+import os,io
+import subprocess
+from datetime import datetime, timedelta
+import oss2
+
+# 阿里云OSS配置
+ACCESS_KEY_ID = '${ak}'
+ACCESS_KEY_SECRET = '${sk}'
+BUCKET_NAME = 'OSS上的Bucket名字'
+ENDPOINT = '阿里云OSS的Endpoint'
+ROOT_PATH = 'ghachive，替换为Bucket下的真实的根目录'
+
+# 获取当前东八区时间
+# beijing_time = datetime.now() 
+beijing_time = datetime.strptime('${datetime}', "%Y-%m-%d %H:%M:%S")
+
+# 获取文件时间，北京时间偏差9个小时即可(时间8小时，gharchive网站产出数据文件晚1个小时，8+1)
+ny_time = beijing_time - timedelta(hours=9)
+
+# 格式化时间
+year = ny_time.strftime('%Y')
+month = ny_time.strftime('%m')
+day = ny_time.strftime('%d')
+hour = ny_time.strftime('%H')
+
+# 打印转换后的时间
+print(f"Converted to data file Time and -9 hour: {year}-{month}-{day} {hour}:00:00")
+
+# 判断小时是否是'0x'格式，是的话去掉前导0
+if hour.startswith('0') and len(hour) > 1:
+    # 去掉前导的'0'
+    hour = hour[1:]
+
+try:
+    # 构建wget命令
+    url = f"https://data.gharchive.org/{year}-{month}-{day}-{hour}.json.gz"
+    cmd = ["wget", "-qO-", url]
+    print(f"wget cmd: {cmd}")
+
+    # 执行wget命令并捕获输出
+    wget_output = subprocess.check_output(cmd)
+    print(f"Wget file done...")
+
+    # 将输出转换为内存中的文件对象
+    file_obj = io.BytesIO(wget_output)
+except Exception as e:
+    print(f"An error occurred: {e}")
+    file_obj = None
+    raise
+
+if file_obj:
+    try:
+        # 初始化阿里云OSS
+        auth = oss2.Auth(ACCESS_KEY_ID, ACCESS_KEY_SECRET)
+        bucket = oss2.Bucket(auth, ENDPOINT, BUCKET_NAME)
+
+        # 上传文件到OSS
+        oss_path = f"{ROOT_PATH}/{year}/{month}/{day}/{year}-{month}-{day}-{hour}.json.gz"
+        print(f"osspath: {oss_path}")
+        bucket.put_object(oss_path, file_obj)
+        print(f"Put file to oss done...")
+    except Exception as e:
+        print(f"An error occurred: {e}")
+    finally:
+        # 关闭内存中的文件对象
+        file_obj.close()
+```
+

+
+### 开发任务：数据加载任务（**L**oad）
+
+云器Lakehouse Studio支持通过离线同步任务，将数据从数据湖加载到Lakehouse的Table里，以优化的格式进行存储，并且便于细粒度的权限管理。
+
+![](.topwrite/assets/image_1734348942887.png)
+
+^
+
+### 开发任务：数据清洗与转换（**T**ransform）
+
+云器Lakehouse动态表（Dynamic Table）是一种支持仅处理增量变化数据的表，具备增量刷新优化能力。与传统的ETL任务相比，动态表无需进行全量数据计算，也无需指定增量逻辑（如按分区对齐或使用max(system/event_time)）。用户只需直接声明定义业务逻辑，动态表即可自动进行增量计算优化。
+
+本文使用动态表进行数据清洗和转化。
+
+![](.topwrite/assets/image_1734348956194.png)
+
+^
+
+#### 即席数据分析（Ad Hoc）
+
+云器Lakehouse 内置了便捷的SQL查询界面，可以自由编写SQL代码、使用变量、选择集群，进行灵活的即席数据分析（Ad Hoc）。也便于进行调试运行。
+
+![](.topwrite/assets/image_1734348969154.png)
+
+^
+
+#### 开发任务：AI/ML增强分析
+
+基于Lakehouse Studio提供的JDBC任务节点，可以便捷地连接到MindsDB，进行增强的数据分析。
+
+![](.topwrite/assets/image_1734348988810.png)
+
+^
+
+### 增量同步任务调度
+
+对刚才开发好的ELT任务进行调度定时和依赖关系配置，确保任务按小时周期运行，提交并发布任务，这样就可以从GHArchive按小时同步到一小时前的GitHub事件数据，并进行清洗和转换。
+
+![](.topwrite/assets/image_1734349005883.png)
+
+^
+
+### 补全量数据
+
+对于补数据任务，在云器Lakehouse Studio里，可以与增量任务完全复用，只需要按照全量数据的开始和结束日期配置并执行补数任务即可，来回刷写历史存量数据。
+
+以GHArchive的数据为例，其网站（http://www.gharchive.org/）的数据开始日期为2011年2月12日，则按下图配置补数任务并运行即可实现全量数据的同步，补全量任务可以与增量数据同步任务同时进行，也无需开发新的全量同步任务。
+
+![](.topwrite/assets/image_1734349021555.png)
+
+^
+^
+
+### 任务运维
+
+云器Lakehouse Studio也提供了完善的运维操作界面，比如展示任务的上下游DAG关系，运行状态，进行重跑等运维操作。

+# 使用流程: External Function
+
+## 文档目标：
+
+通过本篇使用流程，您可以实现：
+
+* 调用JAVA NLP 的离线模型（详见[网址](https://github.com/Ruthwik/Sentiment-Analysis)），解析云器Lakehouse 表中字符串的情绪
+* 调用阿里云视觉智能开放平台服务（详见[网址](https://help.aliyun.com/document_detail/203520.htm?spm=a2c4g.601126.0.0.39de5a4eqBtLaC)），解析云器Lakehouse 表中 url 指向的图片数据
+
+（本篇最佳实践使用的环境为基于阿里云的云器 Lakehouse。）
+
+## 操作步骤:
+
+### Step0：准备工作（授权操作）
+
+本步骤目标是：允许云器 Lakehouse 集群访问客户侧的阿里云上的函数计算 FC、对象存储服务 (OSS)。为了完成这个目标，需要创建一个角色，让云器 Lakehouse 扮演这个角色去访问阿里云上的函数计算 FC 和 OSS 服务。
+
+#### 1. 阿里云控制台：在阿里云控制台**访问控制**(RAM)中创建权限策略 (如：CzUdfOssAccess )：
+
+* 进入阿里云 RAM 控制台
+* 左侧导航栏 **权限管理** -> **权限控制**，在**权限控制**界面选择**创建权限策略**
+* 在**创建权限策略**页面选择**脚本编辑**页签（将下面 [] 中的 bucket 名称替换）。
+
+```JSON
+{
+    "Version": "1",
+    "Statement": [
+        {
+            "Effect": "Allow",
+            "Action": [
+                "oss:GetObject",
+                "oss:PutObject",
+                "oss:DeleteObject"
+            ],
+            "Resource": [
+                "acs:oss:*:*: [bucket_name]/*",
+                "acs:oss:*:*:[bucket_name]/*"
+            ]
+        }
+    ]
+}
+```
+
+^
+
+#### 2. 阿里云控制台：在阿里云 RAM 中创建角色（如：CzUDFRole）：
+
+* 在RAM 控制台左侧导航栏 **身份管理** -> **角色**，点击**创建角色**
+* 在**创建角色**页面中，选择类型为**阿里云账号**，在配置角色中填写自定义**角色名称**（如 CzUDFRole），在**选择信任的云账号**中选择**其他云账号**，并写入：1384322691904283（云器 Lakehouse 上海的云主账号），点击**完成**。
+* 编辑**AliyunFCFullAccess 权限策略**，添加下面 "acs:Service": "fc.aliyuncs.com" 部分。
+
+```Properties
+{
+    "Version": "1",
+    "Statement": [
+        {
+            "Action": "fc:*",
+            "Resource": "*",
+            "Effect": "Allow"
+        },
+        {
+            "Action": "ram:PassRole",
+            "Resource": "*",
+            "Effect": "Allow",
+            "Condition": {
+                "StringEquals": {
+                    "acs:Service": "fc.aliyuncs.com"
+                }
+            }
+        }
+    ]
+}
+```
+
+* 创建完成之后，点击**为角色授权**:
+* 在**系统策略**中，将**AliyunFCFullAccess**策略授权给该角色 CzUDFRole。
+* 在**自定义策略**中，将刚创建的策略（**CzUdfOssAccess**）授权给该角色。
+
+#### 3. 在角色 CzUDFRole 详情页中，获取该角色的 RoleARN 信息：
+
+* 修改 CzUDFRole 的**信任策略**：
+
+```Python
+{
+  "Statement": [
+    {
+      "Action": "sts:AssumeRole",
+      "Effect": "Allow",
+      "Principal": {
+        "RAM": [
+          "acs:ram::1384322691904283:root"
+        ],
+        "Service": [
+          "fc.aliyuncs.com"
+        ]
+      }
+    }
+  ],
+  "Version": "1"
+}
+```
+
+***
+
+### 场景1: 调用JAVA NLP 的离线模型：
+
+#### &#x20;1. 编写代码
+
+* 基于 Hive UDF API 编写 UDF，以下是实现大小写转换的示例代码:
+
+```java
+package com.example;
+
+import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
+import org.apache.hadoop.hive.ql.metadata.HiveException;
+import org.apache.hadoop.hive.ql.udf.generic.GenericUDF;
+import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspector;
+import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector;
+import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector.PrimitiveCategory;
+import org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory;
+
+import java.util.Locale;
+
+public class GenericUdfUpper extends GenericUDF {
+  @Override
+  public ObjectInspector initialize(ObjectInspector[] arguments) throws UDFArgumentException {
+    checkArgsSize(arguments, 1, 1);
+    checkArgPrimitive(arguments, 0);
+    if (((PrimitiveObjectInspector) arguments[0]).getPrimitiveCategory() != PrimitiveCategory.STRING) {
+      throw new UDFArgumentException("argument 0 requires to be string rather than " + arguments[0].getTypeName());
+    }
+    return PrimitiveObjectInspectorFactory.javaStringObjectInspector;
+  }
+
+  @Override
+  public Object evaluate(DeferredObject[] arguments) throws HiveException {
+    Object arg = arguments[0].get();
+    if (arg == null) {
+      return null;
+    }
+    return ((String) arg).toUpperCase(Locale.ROOT);
+  }
+
+  @Override
+  public String getDisplayString(String[] children) {
+    return "upper";
+  }
+}
+```
+
+* 编译代码生成 Jar 包和其他依赖文件，打包成 zip 压缩包
+
+#### 2. 上传函数程序包到指定路径
+
+如： `oss://hz-oss-lakehouse/functions/sentiment/UDF_code/SentimentAnalysis.zip`
+
+函数主类：`com.clickzetta.nlp.GenericUDFSentiment`
+
+有两种方法上传文件到指定路径：
+
+* 通过 OSS 客户端直接上传&#x20;
+* 在Lakehouse JDBC 客户端（不支持Lakehouse Web UI 使用 PUT 命令上传）通过 [PUT 命令](PUT.md) 将程序包上传至 [Volume对象](datalake_volume.md)，并在创建函数 DDL 中引用 volume 路径。例如：
+
+```
+-- 上传文件到命名为 fc_volume 的 Volume对象：
+PUT ./SentimentAnalysis.zip to volume fc_volume/udfs/SentimentAnalysis.zip;
+
+-- 在创建函数时引用该 Volume 路径：
+create external function public.sentiment_demo_hz
+    AS 'com.clickzetta.nlp.GenericUDFSentiment' 
+    USING ARCHIVE 'volume://fc_volume/udfs/SentimentAnalysis.zip' 
+    CONNECTION udf_sentiment_bj
+    WITH
+    PROPERTIES (
+        'remote.udf.api' = 'java8.hive2.v0'
+);
+
+```
+
+您也可以指定内部 volume。虽然您可以使用内部 volume，但是在创建 API CONNECTION 中的 code_bucket 参数必须填写外部地址。
+
+* **User Volume 格式地址**:`volume:user://~/upper.jar`
+  * `user` 表示使用 User Volume 协议。
+
+  * `~` 表示当前用户，为固定值。
+
+  * `upper.jar` 表示目标文件名。
+* **Table Volume 格式地址**`volume:table://table_name/upper.jar`
+  * `table` 表示使用 Table Volume 协议。
+  * `table_name` 表示表名，需根据实际情况填写。
+  * `upper.jar` 表示目标文件名。
+
+#### 3. 新建连接（Connection）
+
+```SQL
+create api connection udf_sentiment_bj
+type cloud_function 
+provider = 'aliyun'
+region = 'cn-beijing'
+role_arn = 'acs:ram::1222808864467016:role/czudfrole'
+namespace = 'default'
+code_bucket = 'derek-bj-oss';
+```
+
+**参数解释**：
+
+1. **api_connection**：创建 API 类型的 Connection，用于调用第三方的服务接口；
+
+2. **type**: 连接类型为云函数：cloud\_function，其中具体的属性为：
+
+* provider：云函数提供商，如 aliyun
+* region：云函数所在区域，如'cn-shanghai'
+* role\_arn：创建云函数所扮演的角色，如 acs\:ram::12228000000000000\:role/czudfrole
+* code\_bucket：云函数程序文件所在路径的对象存储 bucket 名称
+
+#### 4.在 Lakehouse 创建 External Function
+
+```SQL
+create external function public.sentiment_demo_hz 
+as 'com.clickzetta.nlp.GenericUDFSentiment' 
+using archive 'oss://hz-oss-lakehouse/functions/sentiment/UDF_code/SentimentAnalysis.zip'
+connection udf_sentiment_hz 
+with properties ( 
+ 'remote.udf.api' = 'java8.hive2.v0', 
+);
+```
+
+**参数解释**：
+
+1. **as**：后面跟的是 Java 函数的主类名
+2. **using**：仅支持编译后的 Java 程序。后面需要接参数 **archive** 表示程序包为 zip 格式的文件；**jar** 表示 Java 程序的 jar 包文件。后面可直接引用文件的 OSS 路径；如果文件已通过[PUT 命令](PUT.md)上传至 [Volume对象](datalake_volume.md)，也可以通过 Volume 路径直接引用函数文件，例如：`USING ARCHIVE 'volume://fc_volume/udfs/SentimentAnalysis.zip' `
+3. **connection**：表示程序中使用的 connection 对象，如 udf\_sentiment\_bj；其中属性信息：
+
+* remote.udf.api：java UDF 请填写为 java8.hive2.v0
+
+#### 5. 执行语义情感分析：
+
+**构造测试数据**：
+
+```SQL
+create table tbl_wisdom_nlp(id int, qoute string);
+
+insert into tbl_wisdom_nlp values(1,"Honesty and diligence should be your eternal mates");
+insert into tbl_wisdom_nlp values(2,"If a man deceives me once, shame on him; if twice,shame on me");
+insert into tbl_wisdom_nlp values(3,"I am so damn happy");
+insert into tbl_wisdom_nlp values(4,"Today is Sunday");
+insert into tbl_wisdom_nlp values(5,"Today is Monday");
+```
+
+**执行语义分析**：
+
+```SQL
+set cz.sql.remote.udf.enabled = true;
+select qoute, public.sentiment_demo(qoute) as sentiment from tbl_wisdom_nlp;
+```
+
+## 场景2：Python UDF：调用第三方视觉处理平台 API 做图像解析
+
+#### 1. 代码文件为 video\_contents.py：
+
+```Python
+from alibabacloud_imagerecog20190930.client import Client
+from alibabacloud_imagerecog20190930.models import RecognizeFoodRequest
+from alibabacloud_tea_openapi.models import Config
+from alibabacloud_tea_util.models import RuntimeOptions
+
+from cz.udf import annotate
+
+@annotate("string->string")
+class image_to_text(object):
+
+    def evaluate(self,url):
+        if url is None:
+            return None
+        try:
+            config = Config(
+                access_key_id='xxxxx',
+                access_key_secret='xxxxxxxx',
+                endpoint='imagerecog.cn-shanghai.aliyuncs.com',
+                region_id='cn-shanghai'
+            )
+            # Initialize a request and set parameters
+            
+            client = Client(config)
+            recognize_food_request = RecognizeFoodRequest(image_url=url)
+            runtime = RuntimeOptions()
+            response = client.recognize_food_with_options(recognize_food_request, runtime)
+
+            if len(str(response.body)) >= 1:
+                return str(response.body)
+            else:
+                return ""
+        except Exception as exc:
+            return "[error] " + exc.__str__()
+        finally:
+            pass
+
+#if __name__ == "__main__":
+#   import sys
+#    to_text = image_to_text()
+#    for url in sys.argv[1:]:
+#        print(f"{to_text.evaluate(url)}")
+```
+
+#### 2. 复用*场景一*中的 connection
+
+#### 3. 新建 External Function
+
+```Python
+create external function public.image_to_text
+as 'video_contents.image_to_text'    # 脚本名称 + 类名称
+using archive 'oss://derek-bj-oss/bj_remote_udf/image_to_text/image_to_text.zip'
+connection udf_sentiment_bj2
+with properties (
+ 'remote.udf.api' = 'python3.mc.v0',   
+);
+```
+
+**参数解释**:
+
+1. As 后面为python 模块名 + 主类名，如主程序文件为 video\_contents.py，主类名为 image\_to\_text，as 后的参数为`'video_contents.image_to_text'`
+2. **using archive / file**：py 文件需打包为 zip 格式的文件；同时支持单文件脚本，用 file 参数指定
+
+* **connection**：表示程序中使用的 connection 对象，如 udf\_sentiment\_bj；其中属性信息：
+
+  * remote.udf.api：Python 语言函数请填写 python3.mc.v0
+
+#### 4. 建测试数据验证
+
+将以下4个图片导入到 OSS 中，并生成 public url 存储到 Lakehouse 表中。可以直接用以下 SQL 构造测试表：
+
+```SQL
+create table tbl_images(id int, url string);
+
+insert into tbl_images values(1,'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood1.jpg');
+insert into tbl_images values(2,'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood2.jpg');
+insert into tbl_images values(3,'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood3.jpg');
+insert into tbl_images values(4,'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood4.jpg');
+```
+
+执行查询：
+
+```SQL
+set cz.sql.remote.udf.enabled = true;
+select id, public.image_to_text(url) from tbl_images;
+```

+# External Function 开发指南（Python3）
+
+## 目标：
+
+本文目标是帮助开发者掌握用 Python 语言编写外部函数处理云器 Lakehouse 中的数据。
+
+## 注意事项：
+
+> * **Python 版本**： 仅支持 Python 3.10。若依赖包含共享对象文件（.so）的原生库，此类库必须与 Python 3.10 ABI (Application Binary Interface) 兼容。
+> * **部署包格式**： 支持独立的 `.py` 脚本文件，或以 `.zip` 格式归档的程序包。
+> * **大型程序包部署**： 若程序及其依赖项压缩后总体积超过 500MB，则必须通过容器镜像方式创建函数。具体操作请参阅教程：[实践：利用Hugging Face 图片识别模型处理图片数据](RemoteFunctionOnACR.md)
+
+## 环境准备：
+
+鉴于 External Function 的上述使用限制，对开发环境有如下具体要求和建议：
+
+1. **无第三方库依赖**：
+   如果您的 Python 脚本不依赖任何第三方库，仅需确保代码具备下文规定的代码结构，且能够在 Python 3.10 环境中正确执行即可。
+
+2. **有第三方库依赖**：
+   如果脚本需要第三方库，则这些依赖库（及其二进制文件）必须与 Python 3.10 ABI (x86\_64 架构) 兼容。
+
+> **跨平台兼容性**： 在 macOS 或 Windows 等非 Linux x86\_64 环境中开发时，Python 依赖库的 ABI 兼容性问题较为常见。为确保一致性和避免潜在错误，强烈推荐使用以下容器镜像作为 Python External Function 的标准开发环境：
+> `quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779`。该镜像提供了预配置的、符合要求的 Linux x86\_64 以及 Python 3.10 的环境。镜像安装请参考本篇文档最后的附录：开发环境镜像安装。
+>
+> &#x20;如果您的开发环境本身即为 x86\_64 架构的 Linux 系统，则仅需确保 Python 版本为 3.10 版本即可。
+
+## 代码结构：
+
+Python 函数的代码结构分为以下几个部分：
+
+* **导入模块**：必选。至少要包含 `from cz.udf import annotate`，导入函数签名模块，云器Lakehouse 才可以识别后续代码中定义的函数签名。
+* **函数签名**：必选。格式为 `@annotate(<signature>)`，`signature`用于定义函数的输入参数和返回值的数据类型。更多函数签名信息。
+* **自定义Python类**：必选。UDF代码的组织单位，定义了实现业务需求的变量及方法。您还可以在代码中引用第三方库或引用文件、表资源。
+* **evaluate** **方法**：必选。位于自定义的Python类中。`evaluate`方法定义了输入参数和返回值。一个Python类中只能包含一个`evaluate`方法。
+
+> 基于上述代码结构，实现一个将字符转换为大写的函数代码如下：
+
+```Python
+#!/usr/bin/env python
+try:
+    from cz.udf import annotate  # 导入模块
+except ImportError:
+    annotate = lambda _: lambda _: _
+
+@annotate("string->string")  # 函数签名
+class Upper(object):         # 自定义 Python 类
+    def evaluate(self, arg):  # evaluate 方法
+        if arg is None:  
+            return None
+        return arg.upper()
+```
+
+## 安装第三方库：
+
+以下载 httpx 和 pydantic 为例，使用下面命令将依赖包下载到主程序文件所在的目录（例子为当前目录）
+
+```Shell
+pip3 install httpx pydantic -t . 
+```
+
+> 注意：当您使用 macOS / Windows 等非 Linux 系统, 或者使用非 X86-64 的设备，或者使用第三方库包含原生代码时，为避免 Python ABI 兼容性问题，强烈建议使用基于 `quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779` 的容器下载第三方依赖，请参考附录：开发环境镜像安装。
+
+## 上传函数
+
+### 上传、压缩包上传
+
+仅适用于打包之后小于 500M 的函数，大于 500M 请参考后续章节：利用镜像方式创建函数
+
+将程序文件、依赖库文件或者模型文件打包为 zip 格式（当前仅支持 zip 格式文件且小于 500M ），例如
+
+```Shell
+cd ./deps
+zip -rq code.zip ./*
+```
+
+将 code.zip 上传至云上对象存储，并授权给云器Lakehouse 的云上角色能访问到对应路径；授权流程不在开发指南中描述，请参考[使用流程：External Function](RemoteFunctionBestPractice.md)。
+您也可以指定内部volume。虽然您可以使用内部volume但是您在创建API CONNECTION中的code bucket参数必须填写外部地址。
+
+* **User Volume 格式地址**： `volume:user://~/upper.jar`
+  * `user` 表示使用 User Volume 协议。
+
+  * `~` 表示当前用户，为固定值。
+
+  * `upper.jar` 表示目标文件名。
+* **Table Volume 格式地址**：`volume:table://table_name/upper.jar`
+  * `table` 表示使用 Table Volume 协议。
+  * `table_name` 表示表名，需根据实际情况填写。
+  * `upper.jar` 表示目标文件名。
+
+### 镜像方式上传：
+
+仅适用于打包之后大于 500M 、或使用 GPU 资源的函数；需要开通阿里云容器镜像服务（免费）
+
+请参考文档：[实践：利用Hugging Face 图片识别模型处理图片数据](RemoteFunctionOnACR.md)
+
+^
+
+## 示例：
+
+目标：利用大语言模型（LLM）服务，根据 Lakehouse 客户表中的**公司名称**列，填写国家规范的所属**一级行业**和**二级行业的信息**。效果如下：
+
+![](.topwrite/assets/20250612-171447.jpeg =675)
+
+> 注意：完成本示例，需要您：
+>
+> 1. 安装了 Docker （主要是为了保证开发环境与云器运行函数的环境一致）
+> 2. 拥有阿里云账号，并开通百炼平台的 API-KEY。参考 [阿里云百炼](https://www.aliyun.com/product/bailian)
+> 3. 已经创建好 API 连接。参考：创建 [API 连接](create-api-connection.md)
+
+### Step1：准备开发环境
+
+1. **安装 Docker**：确保您的本地上安装了 Docker：<https://www.docker.com/>
+
+2. **拉取** **Docker** **镜像**。在本地命令行终端（如 MacOS 的 ternmial）执行：
+
+   ```
+   [Local]# docker pull quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779
+   ```
+
+3. **启动 Docker 容器**。该容器基于 `manylinux2014_x86_64` 镜像，并配置为使用 Python 3.10 环境
+
+   ```
+   [Local]# docker run -it --name cz_func --env PATH="/opt/python/cp310-cp310/bin:$PATH" quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779 bash
+   ```
+
+> 如果容器已经停止，可以用以下命令启动并登录：
+>
+> 1. **启动容器**：
+>
+> ```
+> # docker start cz_func
+> ```
+>
+> 2. **进入容器**：
+>
+> ```
+> # docker exec -it cz_func bash
+> ```
+
+&#x20;    4\.  在 /root 目录下创建文件夹 cz\_llm
+
+```
+[root@docker root]# cd /root ; mkdir cz_llm 
+[root@docker cz_llm]# cd cz_llm
+[root@docker cz_llm]# touch cz_llm.py
+```
+
+&#x20;   5\. `cz_llm.py` 中的程序代码如下：
+
+```
+import os
+from cz.udf import annotate
+import dashscope
+from http import HTTPStatus
+import json
+import sys
+
+@annotate("*->string")
+class llm_call(object):
+    def evaluate(self, text, prompt, api_key, model_name, temperature=0.7, enable_search=False):
+
+        # 设置 API 密钥
+        dashscope.api_key = api_key
+
+        # 构建消息
+        messages = [
+            {"role": "system", "content": prompt},
+            {"role": "user", "content": text}
+        ]
+
+        try:
+            # 调用模型（非流式输出）
+            response = dashscope.Generation.call(
+                model=model_name,
+                messages=messages,
+                stream=False,  # 关闭流式输出
+                result_format='message',
+                temperature=temperature,
+                enable_search=enable_search,
+                top_p=0.8
+            )
+
+            # 处理响应
+            if response.status_code == HTTPStatus.OK:
+                # 非流式输出直接获取完整内容
+                if hasattr(response.output, 'choices') and len(response.output.choices) > 0:
+                    if hasattr(response.output.choices[0].message, 'content'):
+                        return response.output.choices[0].message.content
+                    else:
+                        return "Error: No content in response"
+                else:
+                    return "Error: No choices in response"
+            else:
+                # 返回错误信息
+                return f"Error: Request id: {response.request_id}, Status code: {response.status_code}, error code: {response.code}, error 
+message: {response.message}"
+
+        except Exception as e:
+            # 返回错误信息
+            return f"Error: {str(e)}"
+
+# 测试代码
+if __name__ == "__main__":
+    # 创建实例
+    llm = llm_call()
+    
+    # 配置参数
+    API_KEY = "sk-xxxxxx"  # 替换为你的API密钥
+    MODEL_NAME = "qwen-max"  # 或 qwen-plus, qwen-max 等
+    
+    # 测试示例
+    test_text = '小红书'
+    test_prompt = '请返回该公司的国家规范的一级、二级行业，直接输出结果:一级行业":"xxx","二级行业":"xxx"，言简意赅'
+    
+    print("正在调用LLM...")
+    result = llm.evaluate(test_text, test_prompt, API_KEY, MODEL_NAME, 0, True)
+    
+    print(f"\n输入文本: {test_text}")
+    print(f"系统提示: {test_prompt}")
+    print(f"LLM响应: {result}")
+```
+
+### Step2：下载第三方库
+
+程序依赖第三方包：`dashscope` 需要进行下载（其余为Python 内置， `os`、`http`、`json`、`sys` 为 Python 内置库无需下载。 `cz.udf `创建函数时系统会默认添加）
+
+在开发环境中的命令行终端执行：
+
+```
+[root@docker cz_llm]# pwd
+/root/cz_llm
+
+[root@docker cz_llm]# pip install dashscope -t .
+```
+
+此时目录结构类似于：
+
+![](.topwrite/assets/external_func_2.jpeg)
+
+^
+
+### Step3：本地调试
+
+将以3行做修改，因为当前环境还没有加载 `cz.udf` 库：
+
+```
+...
+2 #from cz.udf import annotate   # 注释掉
+...
+8 #@annotate("*->string")  # 注释掉
+...
+56 API_KEY = "sk-xxxxxx"  # 替换为你的API密钥
+```
+
+其中 API\_KEY 是阿里云百炼平台的 API-KEY ，需要您注册阿里云账号，登录后在这里获取：[阿里云百炼](https://bailian.console.aliyun.com/?spm=5176.12818093_47.console-base_search-panel.dtab-product_sfm.60852cc9WIq2Db\&scm=20140722.S_sfm._.ID_sfm-RL_%E5%A4%A7%E6%A8%A1%E5%9E%8B%E6%9C%8D%E5%8A%A1%E5%B9%B3%E5%8F%B0%E7%99%BE%E7%82%BC%E6%8E%A7%E5%88%B6%E5%8F%B0-LOC_console_console-OR_ser-V_4-P0_0\&tab=api#/api)
+
+注释掉上面两行之后，保存退出编辑脚本。执行：
+
+```
+[root@docker cz_llm]# export PYTHONPATH="${_PWD}:${_PWD}/lib"
+[root@docker cz_llm]# python cz_llm.py 
+正在调用LLM...
+
+输入文本: 小红书
+系统提示: 请返回该公司的国家规范的一级、二级行业，直接输出结果:一级行业":"xxx","二级行业":"xxx"，言简意赅
+LLM响应: "一级行业":"互联网","二级行业":"社交媒体"
+```
+
+### Step4：打包上传
+
+打包之前，请将上面注释掉的两行，解除注释。
+
+```
+...
+2 from cz.udf import annotate   # 去掉注释
+...
+8 @annotate("*->string")  # 去掉注释
+```
+
+执行打包命令，保证当前目录为程序目录（本示例为 `/root/cz_llm`）
+
+```
+[root@docker cz_llm]# pwd
+/root/cz_llm
+[root@docker cz_llm]# zip -rq ../cz_llm.zip ./
+[root@docker cz_llm]# ls ../
+```
+
+> 提示：如果您的环境没有 zip 命令，请利用 yum install zip 尝试下载。下载过程中遇到问题，请参考附录”**安装工具时报错**“
+
+您会发现在 `/root `目录下有一个 `cz_llm.zip` 文件，将这个文件拷贝到 Lakehouse USER VOLUME 对象中：
+
+在 Docker 宿主机中执行：
+
+```
+[Local]# docker cp cz_func:/root/cz_llm.zip ~/Downloads
+```
+
+现在 `cz_llm.zip `在宿主机的用户的 `Downloads` 目录下
+
+我们用 Lakehouse JDBC 客户端（请参考 [Lakehouse JDBC 客户端](connect-with-cli.md)），将文件 put 到 Lakehouse USER VOLUME 中：
+
+```
+PUT '/Users/derekmeng/Downloads/transform_company_id.zip' to USER VOLUME;
+```
+
+![](.topwrite/assets/external_functions_3.jpeg)
+
+### Step5：创建并使用函数：
+
+本步骤依赖您提前创建好 API connection，创建过程请参考：[API Connection ](create-api-connection.md)
+
+```
+CREATE EXTERNAL FUNCTION public.fc_cz_llm
+    AS 'cz_llm.llm_call'   -- 不带py后缀的主程序文件名.主类名
+    USING ARCHIVE 'volume:user://~/cz_llm.zip' 
+    connection sg_fc_api_conn -- 需要提前创建 API Connection
+    WITH PROPERTIES (
+        'remote.udf.api' = 'python3.mc.v0'
+    )
+COMMENT 'Usage: python get_industry_classification.py <text> <prompt> <api_key> <model_name> [temperature] [enable_search]';
+```
+
+创建过程会持续1分钟左右。创建完成后，执行验证函数：（注意替换 `'${api_key}'` ）
+
+```
+SELECT    public.fc_cz_llm (
+          '云器科技',
+          '请返回国家通用的行业分类，返回JSON 并用中文：{"一级行业":"xxx","二级行业":"xxx"}',
+          '${api_key}',
+          'qwen-plus',
+          '0.4',
+          'true'
+          ) AS llm_result;
+```
+
+执行效果：
+
+![](.topwrite/assets/external_function_4.jpeg =660)
+
+## 附录：
+
+### 函数签名：
+
+函数签名格式如下。
+
+```Python
+@annotate(<signature>)
+```
+
+`signature`为字符串，用于标识输入参数和返回值的数据类型。执行UDF时，UDF函数的输入参数和返回值类型要与函数签名指定的类型一致。查询语义解析阶段会检查不符合函数签名定义的用法，检查到类型不匹配时会报错。具体格式如下。
+
+```Python
+'arg_type_list -> type'
+```
+
+其中：
+
+* `arg_type_list`：表示输入参数的数据类型。输入参数可以为多个，用英文逗号（,）分隔。支持的数据类型为BIGINT、STRING、DOUBLE、BOOLEAN、DATETIME、DECIMAL、FLOAT、BINARY、DATE、DECIMAL(precision,scale)、CHAR、VARCHAR、复杂数据类型（ARRAY、MAP、STRUCT）或复杂数据类型嵌套。
+
+* `arg_type_list`还支持星号（\*）或为空（''）：
+
+  * 当`arg_type_list`为星号（\*）时，表示输入参数为任意个数。
+  * 当`arg_type_list`为空（''）时，表示无输入参数。
+
+* `type`：表示返回值的数据类型。UDF只返回一列。支持的数据类型为：BIGINT、STRING、DOUBLE、BOOLEAN、DATETIME、DECIMAL、FLOAT、BINARY、DATE、DECIMAL(precision,scale)、复杂数据类型（ARRAY、MAP、STRUCT）或复杂数据类型嵌套。
+
+合法的函数签名示例如下：
+
+| 函数签名示例                                        | 说明                                                       |
+| --------------------------------------------- | -------------------------------------------------------- |
+| `'bigint,double->string'`                     | 输入参数类型为BIGINT、DOUBLE，返回值类型为STRING。                       |
+| `'*->string'`                                 | 输入任意个参数，返回值类型为STRING。                                    |
+| `'->double'`                                  | 无输入参数，返回值类型为DOUBLE。                                      |
+| `'array<bigint> -> struct<x:string>, y:int>'` | 输入参数类型为ARRAY\<BIGINT>，返回值类型为STRUCT\<x\:string>, y\:int>。 |
+| '->map\<bigint, string>'                      | 无输入参数，返回值类型为MAP\<BIGINT, STRING>。                        |
+
+### 数据类型：
+
+为确保编写Python UDF过程中使用的数据类型与云器 Lakehouse 支持、的数据类型保持一致，您需要关注二者间的数据类型映射关系：
+
+| 云器 Lakehouse 数据类型 | Python 3 数据类型          |
+| ----------------- | ---------------------- |
+| BIGINT            | int                    |
+| BOOLEAN           | bool                   |
+| CHAR              | unicode                |
+| DATE              | datatime.date          |
+| DECIMAL           | decimal.Decimal        |
+| DOUBLE            | float                  |
+| FLOAT             | float                  |
+| INT               | int                    |

+
+### 开发环境镜像安装：
+
+> **适用场景：在非 Linux/非 X86-64 环境或使用含原生代码的第三方库时规避 Python ABI 兼容性问题**
+
+在软件开发过程中，尤其是在使用 Python 进行跨平台或涉及底层原生代码交互时，应用程序二进制接口（ABI）的兼容性问题是一个需要重点关注的方面。当您的开发或部署环境为 macOS、Windows 等非 Linux 系统，或者目标设备架构并非 X86-64（例如 ARM 架构的设备），亦或是项目中引入了包含 C/C++ 等原生代码编译的第三方库时，潜在的 ABI 不兼容风险会显著增加。为了确保 Python 应用的稳定性和可移植性，强烈建议采用标准化的构建环境来下载和编译这些第三方依赖。
+
+**推荐实践：使用** \`\` **容器**
+
+对于提示中提到的具体场景，即在非 Linux 系统（如 macOS、Windows）、非 X86-64 设备，或使用包含原生代码的第三方库时，为了规避 Python ABI 兼容性问题，强烈建议使用基于 `quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779` 的 Docker 容器来下载和构建第三方依赖。
+
+#### **如何操作**：
+
+1. **安装 Docker**：确保您的开发机器上安装了 Docker：<https://www.docker.com/>
+
+2. **拉取镜像**：
+
+   ```
+   docker pull quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779
+   ```
+
+   ^
+
+3. 启动 Docker 容器，该容器基于 `manylinux2014_x86_64` 镜像，并配置为使用 Python 3.10 环境
+
+   ```
+   docker run -it --name cz_func --env PATH="/opt/python/cp310-cp310/bin:$PATH" quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779 bash
+   ```
+
+这样就可以在该环境中，以 Python 3.10 来开发您的 Python 外部函数了。
+
+> 如果容器已经停止，可以用以下命令启动并登录：
+>
+> 1. **启动容器**：
+>
+> ```
+> docker start cz_func
+> ```
+>
+> 2. **进入容器**：
+>
+> ```
+> docker exec -it cz_func bash
+> ```
+>
+> ^
+
+^
+
+然后您应该会看到容器内的 Bash 提示符(提示符的具体样式可能因镜像而异)，例如打印 Python 版本，此时应该显示如下：
+
+```
+[root@cfadeae5f8b0 /]# python --version
+ Python 3.10.8
+```
+
+现在您应该已经成功 "登录" 到您的 `cz_func` 容器中了。
+
+^
+
+#### **镜像使用常见问题**：
+
+1\. **安装工具时报错**
+
+&#x20;   如 `yum install zip` 安装 `zip` 打包工具 ，会遇到诸如下面的错误：
+
+```
+[root@311b32ae3e5f ]# yum install zip
+Loaded plugins: fastestmirror, ovl
+Determining fastest mirrors
+Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was
+14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"
+
+
+ One of the configured repositories failed (Unknown),
+ and yum doesn't have enough cached data to continue. At this point the only
+ safe thing yum can do is fail. There are a few ways to work "fix" this
+...
+            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
+
+Cannot find a valid baseurl for repo: base/7/x86_64
+```
+
+这个错误是因为 CentOS 7 已经在 2024 年 6 月 30 日到达生命周期终点（EOL），官方仓库已经被移到 CentOS vault。`mirrorlist.centos.org` 不再提供 CentOS 7 的仓库服务。
+
+以下是解决方案：
+
+首先，检查网络连接是否正常：
+
+如果网络正常，更新仓库配置以使用 CentOS vault：
+
+```
+# 备份当前的仓库文件
+mkdir -p /etc/yum.repos.d/backup
+cp /etc/yum.repos.d/CentOS-*.repo /etc/yum.repos.d/backup/
+
+# 更新仓库 URL 以使用 vault.centos.org
+sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*.repo
+sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*.repo
+
+# 清理 yum 缓存
+yum clean all
+
+# 现在再次尝试安装 zip
+yum install zip
+```
+
+如果您在中国或者 **vault.centos.org** 访问较慢，可以使用国内镜像源：
+
+使用阿里云镜像：
+
+```
+sed -i 's|baseurl=http://vault.centos.org|baseurl=http://mirrors.aliyun.com/centos-vault|g' /etc/yum.repos.d/CentOS-*.repo
+```
+
+或者使用清华大学镜像：
+
+```
+sed -i 's|baseurl=http://vault.centos.org|baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos-vault|g' /etc/yum.repos.d/CentOS-*.repo
+```
+
+完成这些更改后，`yum install zip` 命令应该就能正常工作了。
+
+^
+
+**2**. **Docker 容器与宿主机文件互拷**
+
+生成了程序包，如果想从容器中拷贝到宿主机，或者反过来从宿主机拷贝到容器中，可以使用下面的命令：
+
+**从容器拷贝到宿主机**：
+
+```
+# docker cp 容器名:容器内路径 宿主机路径，示例：
+docker cp cz_func:/root/gen_emmbedings.zip ~/Downloads
+```
+
+**从宿主机拷贝到容器**：
+
+```
+# docker cp 宿主机路径 容器名:容器内路径# 示例
+docker cp ~/Downloads/file.txt cz_func:/root/
+```
+
+**注意**：
+
+* 容器可以是运行中或已停止状态
+* 使用容器名或容器ID都可以
+* 支持拷贝文件和目录：`docker cp` 会自动识别是文件还是目录
+
+```
+# 拷贝整个目录
+docker cp ~/project 容器名:/root/
+# 拷贝目录内容
+docker cp ~/project/. 容器名:/root/project/
+```
+
+^
+
+* `docker cp` 会自动识别是文件还是目录
+
+* 拷贝目录时会递归拷贝所有子目录和文件
+
+* 目标路径不存在时会自动创建
+
+* 路径末尾加 `/` 与不加的区别：
+
+  * `/app/logs` → 拷贝 logs 目录本身
+  * `/app/logs/.` → 只拷贝 logs 目录下的内容
+
+^

+# 利用Hugging Face 图片识别模型处理图片数据
+
+## 1. 适用场景：
+
+本文创建 Remote Function 的方式是基于阿里云容器镜像创建，这个场景适用于：
+
+* 如果图像解析程序的 Python 依赖包大于 500M，就需要利用本文介绍的方式，即基于容器镜像服务方式创建（如果函数的程序文件包小于 500M，可直接传到对象存储走自动化创建）。
+* 无论程序文件大小，需要使用云上函数计算服务的 GPU 资源时，需要基于容器镜像服务方式创建
+
+## 2.过程演示：
+
+### 2.1 准备
+
+* 场景：利用 Hugging Face 的 image to text 离线模型解析图片内容
+* 模型：Hugging Face 的图像识别模型，请参考[链接](https://huggingface.co/Salesforce/blip-image-captioning-large)
+* 代码：(见附录)
+
+### 2.2 下载模型和依赖库：
+
+（推荐在 x86_64 Linux 主机环境运行）
+
+#### 2.2.1 下载模型
+
+* 安装 huggingface\_hub 模型下载工具：
+
+```Python
+pip3 install huggingface_hub
+```
+
+* 下载模型文件到 model 目录，用 Python/ipython 执行下面脚本
+
+  * repo\_id 为模型名称：参考模型网站：
+
+  ![](.topwrite/assets/remote_udf_image01.jpeg)
+
+  * local\_dir: 本地文件夹，为模型下载的目的地
+  * local_dir_use_symlinks：本地文件夹是否为 mount 点
+
+```Python
+from huggingface_hub import snapshot_download
+repo_id = 'nlpconnect/vit-gpt2-image-captioning'  
+local_dir = './model'
+local_dir_use_symlinks = False
+snapshot_download(repo_id=repo_id, local_dir=local_dir, local_dir_use_symlinks=local_dir_use_symlinks)
+```
+
+#### 2.2.2 下载依赖库：
+
+下载依赖库到 `lib_` 目录 (需要使用 python 特定版本, 建议使用 docker)
+
+将本地创建 `lib_ `文件夹，mount 到 docker 的 `/root/lib_ `，将依赖库下载到`lib_` 中
+
+```Python
+docker run -it -v `pwd`/lib_:/root/lib_ quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779 /bin/bash
+```
+
+在 Docker 环境中执行：
+
+```Python
+cd /root
+/opt/python/cp37-cp37m/bin/python3.7 -m venv venv
+source venv/bin/activate
+mkdir lib_
+pip3 install \
+    -i http://mirrors.cloud.aliyuncs.com/pypi/simple/ \
+    --trusted-host mirrors.cloud.aliyuncs.com \
+    transformers torch pillow \
+    -t "./lib_"
+```
+
+^
+
+### 2.3 写代码：
+
+在与` model`，`lib_` 同级目录创建代码文件，如 `hgf_image2text.py` ，代码参考附录
+
+### 2.4 测试代码：
+
+在Docker `quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779` 中执行测试
+
+```Python
+docker run -it -v `pwd`:/app quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779 /bin/bash
+```
+
+在 Docker 环境中执行：
+
+```Python
+cd /app
+export PYTHONPATH=`pwd`:`pwd`/lib:`pwd`/lib_
+python3 hgf_image2text.py https://huggingface.co/datasets/mishig/sample_images/resolve/main/savanna.jpg https://huggingface.co/datasets/mishig/sample_images/resolve/main/airport.jpg
+```
+
+测试成功后，打包镜像上传至阿里云 ACR 服务
+
+### 2.5 打包并上传镜像：
+
+#### 2.5.1 准备镜像：
+
+在与` model`，`lib_` ， `hgf_image2text.py` 同级目录中创建 Dockerfile 文件，内容如下：

+RUN mkdir -p /app
+WORKDIR /app
+COPY . /app
+```
+
+增加云器 Lakehouse 的启动程序(可联系云器支持同学获取)，并解压到当前目录。至此，当前的目录应包含：
+
+`model`,`lib_` ,`hgf_image2text.py` , `Dockerfile` 文件夹和文件，以及从云器启动程序解压出的 `bootstrap`, `lib`, `cz`。
+

+# EXTERNAL FUNCTION
+
+## 概述
+
+EXTERNAL FUNCTION（REMOTE FUNCTION）是在云器 Lakehouse 中通过 Python 和 Java 语言创建的自定义函数（UDF），通过远程服务执行（支持的远程服务包括：阿里云的函数计算 FC、腾讯云的云函数 SCF）。在执行过程中可调用：
+
+* 在线服务：以 API 形式对外提供的在线服务，例如：AI 在线模型服务（如大语言模型 API、云平台提供的在线 AI API 服务）。
+* 离线功能：将特定功能函数代码、依赖库、模型和数据等文件打包成的离线服务包，例如从 Hugging Face 下载的图片识别模型等。
+
+云器 Lakehouse 通过创建 API CONNECTION，在元数据中保存外部函数计算服务的连接和访问信息。EXTERNAL FUNCTION 通过 HTTP 协议调用外部函数计算服务进行数据处理，并返回结果。
+![](.topwrite/assets/a7546df1-be39-41e9-9c80-e0e90ce3d353.svg)
+云器 Lakehouse 平台通过用户的预先授权，在创建外部函数时，将自动在客户账号下的函数计算服务中创建对应的函数。当用户在 SQL 查询中使用外部函数时，外部函数会实现与外部计算服务的安全连接、数据处理，并返回查询结果。
+
+## EXTERNAL FUNCTION 创建流程
+
+请参考：[使用流程: External Function](RemoteFunctionBestPractice.md)
+
+* 用户开通云上的函数计算服务（如阿里云的函数计算 FC）和对象存储服务。
+* 将函数执行代码、可执行文件、依赖库、模型和数据文件打包上传至对象存储。
+* 授予云器 Lakehouse 操作上述服务和访问函数文件（包）的权限。
+* 用户执行连接和外部函数 DDL 语句以生成 UDF，并在查询中使用。
+
+## EXTERNAL FUNCTION 执行过程
+
+* 用户在云器 Lakehouse SQL 语句中调用 External Function。
+* 云器 Lakehouse 根据提供的服务地址和认证信息，发送 HTTP 请求以调用并运行函数。
+* 云器 Lakehouse 获取响应信息并返回结果。
+
+## EXTERNAL FUNCTION 优势
+
+* 可以使用 Remote Function 调用外部丰富的数据处理能力，以补充传统 SQL 计算模型。例如，可调用大语言模型（LLM）、图像处理、音视频处理等服务或能力，以补充 SQL 在非结构化数据处理方面的能力。
+* 可以直接访问外部网络，不受云器 Lakehouse 网络约束。
+
+## 使用限制
+
+* 目前只支持 Java 和 Python 编程语言，支持的运行环境为 Java 8 和 Python 3.10。
+* 如果依赖原生库（如包含 .so 文件的库），需要兼容 Python 3.10 的 ABI。
+* 当程序及其依赖文件压缩后大于 500 MB 时，需要以容器镜像方式创建函数，请参考[实践：利用Hugging Face 图片识别模型处理图片数据](RemoteFunctionOnACR.md)。
+
+## EXTERNAL FUNCTION 收费
+
+* 支持自定义函数类型：UDF，UDAF，UDTF
+* 远程服务调用的费用：参考云厂商的函数计算服务费用信息（阿里云请参考[链接](https://help.aliyun.com/zh/fc/product-overview/billing-overview?spm=a2c4g.11186623.0.0.4d5b19b3rrOy7Y)，腾讯云请参考[链接](https://cloud.tencent.com/document/product/583/17299)）。
+* 使用云器 Lakehouse 的计算资源所产生的计算费用。
+* 数据传输费用：任何涉及公网数据流出的费用。内网传输不产生费用。
+
+## 使用 REMOTE FUNCTION 开发 UDF 函数
+
+请参考以下开发指南：
+
+* [External Function(Java)](ExternalFunctionDevGuideJava.md)
+* [External Function(Python3)](RemoteFunctionDevGuidePython3.md)

+## 功能
+
+本命令用于回收指定角色的权限。通过使用 REVOKE 语句，可以对不同级别的权限进行回收，包括 workspace、workspace 对象、schema 和 schema 对象等级别。
+
+## Workspace 用户和角色权限管理语法
+
+```SQL
+REVOKE [workspacePrivileges | workspaceObjectPrivileges | schemaPrivileges | schemaObjectPrivileges]
+ON [WORKSPACE | {ROLE | SCHEMA | VCLUSTER | DATALAKE | FUNCTION | workspace_object_name | SCHEMA | {TABLE | VIEW | MATERIALIZED VIEW} schema_object_name]
+FROM ROLE role_name;
+```
+
+### 参数说明
+
+1.  **workspacePrivileges**：在 workspace 下创建对象的权限，例如 `CREATE SCHEMA` 和 `CREATE VCLUSTER`。
+
+2.  **workspaceObjectPrivileges**：对 workspace 下对象的修改和查看元数据等权限，例如 `ALTER`、`DROP`、`READ METADATA` 和 `ALL [PRIVILEGES]`。
+
+3.  **schemaPrivileges**：在 schema 下创建对象的权限，例如 `CREATE TABLE`、`CREATE VIEW` 和 `CREATE MATERIALIZED VIEW`。
+
+4.  **schemaObjectPrivileges**：对 schema 下对象的修改、删除、查询等权限，例如 `ALTER`、`DROP`、`SELECT`、`INSERT`、`READ METADATA` 和 `ALL`。
+
+## 示例
+
+1.  回收角色 `simple_role` 在 `lakehouse_public` workspace 下创建 `VIRTUAL CLUSTER` 的权限：
+
+    ```SQL
+   REVOKE CREATE VCLUSTER ON WORKSPACE lakehouse_public FROM ROLE simple_role;
+   ```
+
+2.  回收角色 `simple_role` 在名为 `default` 的 `VIRTUAL CLUSTER` 上的 `ALTER` 权限：
+
+    ```SQL
+   REVOKE ALTER VCLUSTER ON VCLUSTER default FROM ROLE simple_role;
+   ```
+
+3.  回收角色 `uat_demo` 在 `public` schema 下创建表和视图的权限：
+
+    ```SQL
+   REVOKE CREATE VIEW, CREATE TABLE ON SCHEMA public FROM ROLE uat_demo;
+   ```
+
+4.  回收角色 `reporting_role` 在名为 `sales_data` 的 `DATALAKE` 上的 `READ METADATA` 权限：
+
+    ```SQL
+   REVOKE READ METADATA ON DATALAKE sales_data FROM ROLE reporting_role;
+   ```
+
+5.  回收角色 `admin_role` 在名为 `order_summary` 的 `FUNCTION` 上的 `ALTER` 和 `DROP` 权限：
+
+    ```SQL
+   REVOKE ALTER, DROP ON FUNCTION order_summary FROM ROLE admin_role;
+   ```
+
+6.  回收角色 `analyst_role` 在 `public` schema 下名为 `customer_orders` 的 `TABLE` 上的 `SELECT` 和 `INSERT` 权限：
+
+    ```SQL
+   REVOKE SELECT, INSERT ON TABLE public.customer_orders FROM ROLE analyst_role;
+   ```
+
+
+
+# Instance Role 权限管理
+LakeHouse 支持对 Instance Role 的跨工作空间权限进行细粒度回收，确保权限管控的灵活性和安全性。
+
+## 语法说明
+```sql
+-- 回收 Instance Role 对工作空间的权限  
+REVOKE <privilege> ON WORKSPACE <workspace_name> FROM INSTANCE ROLE <role_name>;  
+
+-- 回收 Instance Role 对表/库的权限  
+REVOKE <privilege> ON TABLE <workspace>.<schema>.<table> FROM INSTANCE ROLE <role_name>;  
+
+REVOKE <privilege> ON DATABASE <workspace>.<schema> FROM INSTANCE ROLE <role_name>;  
+
+-- 移除用户的 Instance Role 归属  
+REVOKE INSTANCE ROLE <role_name> FROM USER <user_name>;  
+```
+
+## 示例
+```sql
+-- 回收工作空间全部权限  
+REVOKE ALL ON WORKSPACE ws1 FROM INSTANCE ROLE inst_role;  
+
+-- 验证回收结果（预期无 ALL 权限）  
+SHOW GRANTS TO INSTANCE ROLE inst_role;  
+
+-- 回收单表权限  
+REVOKE ALL ON TABLE ws1.public.sales FROM INSTANCE ROLE inst_role;  
+
+-- 移除用户的 Instance Role  
+REVOKE INSTANCE ROLE inst_role FROM USER lh_engine_test_01;

+# SCHEMA
+
+在数据库设计中，SCHEMA是组织和管理数据的关键概念。它为用户提供了一种灵活的方式来定义数据的结构和关系。通过使用 SCHEMA，可以将相关的数据库对象（如表、视图等）进行逻辑分组，使得数据组织更加清晰，便于维护和扩展。
+
+## SCHEMA的主要作用
+
+1. **逻辑分组**：SCHEMA允许用户根据业务功能、数据类型或其他标准，将数据库对象进行逻辑分组，从而实现数据的有序组织。
+2. **权限管理**：通过SCHEMA，可以对数据库对象实施更精细的权限控制。用户可以针对不同的SCHEMA设置相应的访问权限，以实现安全管理。
+3. **命名空间**：SCHEMA 提供了命名空间功能，有助于避免对象名称的冲突。在大型项目或多用户环境中，这一点尤为重要。
+4. **简化操作**：用户可以通过 `USE` 命令快速切换当前操作的 SCHEMA，简化了日常数据库操作，提高了工作效率。
+
+## SCHEMA管理命令
+
+云器 Lakehouse 提供了一系列的命令来管理 SCHEMA，包括创建、删除、查看详情、切换以及列举等。
+
+* [创建SCHEMA](CREATESCHEMA.md)：使用 `CREATE SCHEMA` 命令可以创建一个新的 SCHEMA。例如，`CREATE SCHEMA myschema;` 会创建一个名为 `myschema` 的 SCHEMA。
+* [删除SCHEMA](DROPSCHEMA.md)：如果某个 SCHEMA 不再需要，可以使用 `DROP SCHEMA` 命令将其删除。执行删除操作前，请确保已对相关数据进行备份或迁移，以防止数据丢失。
+* [查看SCHEMA详情](DESCSCHEMAS.md)：通过 `DESC SCHEMAS` 命令，用户可以查看当前空间中所有 SCHEMA 的详细信息，包括创建时间、对象数量等。
+* [切换SCHEMA](USESCHEMA.md)：使用 `USE SCHEMA` 命令可以切换当前会话的默认 SCHEMA。例如，`USE SCHEMA myschema;` 会将 `myschema` 设置为当前会话的默认 SCHEMA。
+* [列举当前空间所有SCHEMA](show-schemas.md)：通过 `SHOW SCHEMAS` 命令，用户可以列举出当前空间中所有的 SCHEMA，便于管理和选择。
+* [修改SCHEMA](<ALTER-SCHEMA.md>)：支持修改 SCHEMA 的属性和重命名 SCHEMA。
+
+## 应用示例
+
+以下是一个应用示例，展示了如何创建和切换 SCHEMA：
+
+```sql
+-- 创建一个新的SCHEMA
+CREATE SCHEMA myschema;
+
+-- 在创建表时指定SCHEMA
+CREATE TABLE myschema.mytable (
+    id INT PRIMARY KEY,
+    name VARCHAR(50)
+);
+
+-- 切换到刚刚创建的SCHEMA
+USE SCHEMA myschema;
+
+-- 在当前SCHEMA下查询表结构
+DESC TABLE mytable;
+
+-- 向表中插入数据
+INSERT INTO myschema.mytable (id, name) VALUES (1, '张三');
+
+-- 查询表中的数据
+SELECT * FROM myschema.mytable;
+```

+# SMALLINT
+
+16位有符号整型（SMALLINT）是一种整数数据类型，用于存储范围在 -32,768 到 32,767 之间的整数值。这种数据类型占用两个字节（16位）的存储空间，适用于存储较小的整数值，以节省存储空间。
+
+## 语法
+```
+SMALLINT
+```
+
+## 示例
+1. 创建一个包含SMALLINT类型列的表：
+
+   ```sql
+   CREATE TABLE example_table (
+       id INT,
+       name VARCHAR(50),
+       smallint_value SMALLINT
+   );
+   ```
+
+2. 向表中插入SMALLINT类型的数据：
+
+   ```sql
+   INSERT INTO example_table (id, name, smallint_value)
+   VALUES (1, '张三', -32768);
+   ```
+
+3. 查询表中的SMALLINT类型数据：
+
+   ```sql
+   SELECT * FROM example_table;
+   ```
+
+4. 使用SMALLINT类型数据进行条件筛选：
+
+   ```sql
+   SELECT * FROM example_table WHERE smallint_value > 0;
+   ```
+
+5. 对SMALLINT类型的数据进行数学运算：
+
+   ```sql
+   SELECT smallint_value + 1 FROM example_table;
+   ```
+
+## 注意事项
+- 请确保插入的数据在SMALLINT类型的有效范围内，否则可能导致数据溢出或截断。
+- 在进行数学运算时，请注意数据类型之间的隐式转换，以避免意外的结果。

+
+### 核心优势对比
+
+| 特性           | Spark           | Lakehouse  | 优势      |
+| ------------ | --------------- | ---------- | ------- |
+| **建表方式**     | DataFrame API为主 | SQL DDL标准化 | 降低学习成本  |
+| **分区管理**     | 手动管理            | 隐藏分区+转换分区  | 自动优化    |
+| **数据组织**     | 文件级别            | 表级别管理      | 更高效的元数据 |
+| **Schema演进** | 需要重写            | 原地演进       | 灵活性更强   |
+
+### DataFrame到DDL的转换
+
+**Spark DataFrame方式**：
+
+```python
+# Spark DataFrame创建表
+df = spark.read.parquet("path/to/data")
+df.write.partitionBy("year", "month") \
+  .bucketBy(10, "user_id") \
+  .sortBy("timestamp") \
+  .saveAsTable("user_events")
+```
+
+**Lakehouse DDL方式**：
+
+```sql
+-- 对应的Lakehouse建表语句
+CREATE TABLE user_events (
+    user_id BIGINT,
+    event_type STRING,
+    timestamp TIMESTAMP,
+    properties MAP<STRING, STRING>,
+    year INT GENERATED ALWAYS AS (year(timestamp)),
+    month INT GENERATED ALWAYS AS (month(timestamp))
+) 
+PARTITIONED BY (year, month)
+CLUSTERED BY (user_id) SORTED BY (timestamp) INTO 10 BUCKETS
+COMMENT '用户事件表';
+```
+
+### 高级特性映射
+
+**1. 动态分区处理**
+
+```sql
+-- Spark需要手动处理动态分区
+-- Lakehouse使用转换分区自动处理
+CREATE TABLE events (
+    event_time TIMESTAMP,
+    user_id STRING,
+    event_data STRING
+) PARTITIONED BY (
+    days(event_time),        -- 自动按天分区
+    bucket(100, user_id)     -- 自动按用户ID分桶
+);
+```
+
+**2. Schema合并与演进**
+
+```sql
+-- Lakehouse原生支持Schema演进
+ALTER TABLE events ADD COLUMN new_field STRING;
+ALTER TABLE events CHANGE COLUMN event_data TYPE JSON;
+```
+
+**3. 复杂数据类型处理**
+
+```sql
+-- 完全兼容Spark的复杂类型
+CREATE TABLE user_profiles (
+    user_id BIGINT,
+    tags ARRAY<STRING>,                          -- 标签数组
+    attributes MAP<STRING, STRING>,              -- 属性映射
+    address STRUCT<                              -- 嵌套结构
+        street: STRING,
+        city: STRING,
+        coordinates: STRUCT<lat: DOUBLE, lon: DOUBLE>
+    >,
+    preferences JSON                             -- JSON灵活字段
+);
+```
+
+### 性能优化建议
+
+```sql
+-- 针对Spark用户的优化建表模式
+CREATE TABLE optimized_fact_table (
+    -- 业务字段
+    transaction_id BIGINT IDENTITY(1),
+    user_id BIGINT,
+    product_id INT,
+    amount DECIMAL(18, 2),
+    transaction_time TIMESTAMP,
+    
+    -- 生成分区字段（替代Spark的手动分区）
+    tx_date STRING GENERATED ALWAYS AS (date_format(transaction_time, 'yyyy-MM-dd')),
+    tx_hour INT GENERATED ALWAYS AS (hour(transaction_time))
+) 
+PARTITIONED BY (tx_date, tx_hour)              -- 双层分区
+CLUSTERED BY (user_id) INTO 256 BUCKETS        -- 用户维度分桶
+PROPERTIES (
+    'data_lifecycle' = '730',                   -- 2年生命周期
+    'partition.cache.policy.latest.count' = '7' -- 缓存最近7天
+);
+```
+
+***
+
+## Hive用户迁移指南
+
+### 完美的语法兼容性
+
+云器Lakehouse完全兼容Hive的分区语法，同时提供了更强大的功能：
+
+**传统Hive建表**：
+
+```sql
+-- Hive风格（完全支持）
+CREATE TABLE IF NOT EXISTS sales_fact (
+    order_id BIGINT,
+    product_id INT,
+    quantity INT,
+    price DECIMAL(10,2)
+) PARTITIONED BY (
+    dt STRING,
+    region STRING
+)
+STORED AS PARQUET
+TBLPROPERTIES ('transactional'='true');
+```
+
+**Lakehouse增强版**：
+
+```sql
+-- 相同语法，更强性能
+CREATE TABLE IF NOT EXISTS sales_fact (
+    order_id BIGINT,
+    product_id INT,
+    quantity INT,
+    price DECIMAL(10,2),
+    order_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP  -- 新增：默认值
+) PARTITIONED BY (
+    dt STRING,
+    region STRING
+)
+COMMENT 'Sales fact table with enhanced features'
+PROPERTIES (
+    'data_lifecycle' = '1095',      -- 新增：3年生命周期管理
+    'change_tracking' = 'false'     -- 新增：CDC能力预留
+);
+```
+
+### 分区策略升级
+
+**静态分区到智能分区的进化**：
+
+```sql
+-- Hive传统方式：需要手动管理分区
+INSERT OVERWRITE TABLE sales_fact PARTITION(dt='2024-06-20', region='CN')
+SELECT ...;
+
+-- Lakehouse智能方式：自动分区管理
+CREATE TABLE sales_fact_smart (
+    order_id BIGINT,
+    order_time TIMESTAMP,
+    region_code STRING,
+    amount DECIMAL(10,2),
+    -- 自动生成分区字段
+    dt STRING GENERATED ALWAYS AS (date_format(order_time, 'yyyy-MM-dd'))
+) PARTITIONED BY (dt, region_code);
+
+-- 插入时自动处理分区
+INSERT INTO sales_fact_smart (order_id, order_time, region_code, amount)
+VALUES (1001, CURRENT_TIMESTAMP, 'CN', 99.99);
+```
+
+### 事务表能力增强
+
+```sql
+-- Hive事务表限制多，Lakehouse原生支持
+CREATE TABLE transaction_table (
+    id BIGINT PRIMARY KEY,           -- 原生主键支持
+    data STRING,
+    version INT,
+    updated_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+) 
+CLUSTERED BY (id) INTO 16 BUCKETS   -- 必需的分桶优化
+PROPERTIES (
+    'data_retention_days' = '7'      -- Time Travel能力
+);
+```
+
+### 性能提升对比
+
+| 操作类型     | Hive (MapReduce) | Lakehouse | 性能提升 |
+| -------- | ---------------- | --------- | ---- |
+| 建表速度     | 秒级               | 毫秒级       | 10x  |
+| 分区裁剪     | 文件级扫描            | 元数据裁剪     | 100x |
+| Schema变更 | 需重建              | 在线变更      | ∞    |
+| 小文件合并    | 手动维护             | 自动优化      | 自动化  |
+

+
+## MaxCompute用户迁移指南
+
+### 语法对照与增强
+
+MaxCompute用户会发现云器Lakehouse的语法非常熟悉，同时功能更加强大：
+
+**MaxCompute建表**：
+
+```sql
+-- MaxCompute语法
+CREATE TABLE IF NOT EXISTS sale_detail(
+    shop_name STRING,
+    customer_id STRING,
+    total_price DOUBLE
+)
+PARTITIONED BY (sale_date STRING, region STRING)
+LIFECYCLE 730;
+```
+
+**Lakehouse对应语法**：
+
+```sql
+-- 几乎相同的语法，更多功能
+CREATE TABLE IF NOT EXISTS sale_detail(
+    shop_name STRING,
+    customer_id STRING,
+    total_price DOUBLE,
+    -- 新增能力
+    create_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    row_id BIGINT IDENTITY(1)  -- 自增主键
+)
+PARTITIONED BY (sale_date STRING, region STRING)
+PROPERTIES (
+    'data_lifecycle' = '730',  -- 生命周期（天）
+    'data_retention_days' = '7' -- Time Travel保留期
+);
+```
+
+### 函数兼容性
+
+```sql
+-- MaxCompute函数 → Lakehouse函数映射
+CREATE TABLE datetime_example (
+    id INT,
+    -- MaxCompute: GETDATE() → Lakehouse: CURRENT_TIMESTAMP
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    
+    -- 日期函数完全兼容
+    year_part INT GENERATED ALWAYS AS (YEAR(created_at)),
+    month_part INT GENERATED ALWAYS AS (MONTH(created_at)),
+    
+    -- 字符串函数相同
+    user_name STRING,
+    name_length INT GENERATED ALWAYS AS (LENGTH(user_name))
+);
+```
+
+### 资源管理对比
+
+| 特性   | MaxCompute | Lakehouse  | 优势   |
+| ---- | ---------- | ---------- | ---- |
+| 计算资源 | 预付费CU      | 弹性VCLUSTER | 按需付费 |
+| 存储限制 | 项目配额       | 无限扩展       | 更灵活  |
+| 并发控制 | 作业队列       | 动态调度       | 更高效  |
+| 跨地域  | 需要迁移       | 原生支持       | 全球化  |
+
+***
+
+## Snowflake用户迁移指南
+
+### 架构理念对比
+
+两者都是云原生数据仓库，但Lakehouse提供了更多的控制权：
+
+**Snowflake风格建表**：
+
+```sql
+-- Snowflake
+CREATE OR REPLACE TABLE customer_transactions (
+    transaction_id NUMBER AUTOINCREMENT,
+    customer_id VARCHAR,
+    amount NUMBER(18,2),
+    transaction_date TIMESTAMP_NTZ,
+    status VARCHAR DEFAULT 'PENDING'
+) CLUSTER BY (customer_id);
+```
+
+**Lakehouse增强版**：
+
+```sql
+-- Lakehouse：更明确的优化控制
+CREATE TABLE IF NOT EXISTS customer_transactions (
+    transaction_id BIGINT IDENTITY(1),  -- 对应AUTOINCREMENT
+    customer_id VARCHAR(100),
+    amount DECIMAL(18,2),
+    transaction_date TIMESTAMP_NTZ,
+    status VARCHAR(20) DEFAULT 'PENDING',
+    
+    -- 额外优化字段
+    tx_date STRING GENERATED ALWAYS AS (date_format(transaction_date, 'yyyy-MM-dd')),
+    INDEX idx_customer (customer_id) BLOOMFILTER  -- 显式索引
+) 
+PARTITIONED BY (tx_date)  -- 显式分区策略
+CLUSTERED BY (customer_id) INTO 128 BUCKETS  -- 明确分桶数
+COMMENT 'Customer transaction table with explicit optimizations';
+```
+
+### 时间旅行与克隆
+
+```sql
+-- Snowflake Time Travel → Lakehouse Time Travel
+CREATE TABLE orders_backup AS
+SELECT * FROM orders;  -- 立即复制
+
+-- Lakehouse还支持：
+ALTER TABLE orders SET PROPERTIES ('data_retention_days' = '30');  -- 30天历史
+-- 查询历史数据
+SELECT * FROM orders TIMESTAMP AS OF '2024-06-01 00:00:00';
+```
+
+### 性能调优差异
+
+```sql
+-- Snowflake：自动优化
+-- Lakehouse：提供更多调优选项
+
+CREATE TABLE large_fact_table (
+    -- 列定义
+    fact_id BIGINT,
+    dim1_id INT,
+    dim2_id INT,
+    measure1 DECIMAL(18,4),
+    measure2 DECIMAL(18,4),
+    fact_time TIMESTAMP,
+    
+    -- 性能优化
+    fact_date STRING GENERATED ALWAYS AS (date_format(fact_time, 'yyyy-MM-dd'))
+) 
+PARTITIONED BY (fact_date)
+CLUSTERED BY (dim1_id, dim2_id) 
+    SORTED BY (fact_time DESC)    -- 额外的排序优化
+    INTO 256 BUCKETS              -- 精确控制并行度
+PROPERTIES (
+    'partition.cache.policy.latest.count' = '30'  -- 缓存策略
+);
+```
+
+***
+
+## Databricks用户迁移指南
+
+### Delta Lake理念的深度融合
+
+Lakehouse借鉴了Delta Lake的设计理念，提供类似但更简洁的语法：
+
+**Databricks Delta表**：
+
+```python
+# Databricks Python API
+(spark.sql("""
+    CREATE TABLE IF NOT EXISTS events (
+        event_id LONG,
+        event_time TIMESTAMP,
+        user_id STRING,
+        event_type STRING,
+        properties MAP<STRING, STRING>
+    ) USING DELTA
+    PARTITIONED BY (date(event_time))
+    TBLPROPERTIES (
+        'delta.deletedFileRetentionDuration' = '7 days',
+        'delta.optimizeWrite' = 'true'
+    )
+"""))
+```
+
+**Lakehouse原生SQL**：
+
+```sql
+-- 纯SQL实现，无需Python包装
+CREATE TABLE IF NOT EXISTS events (
+    event_id BIGINT,
+    event_time TIMESTAMP,
+    user_id STRING,
+    event_type STRING,

+
+## 传统数据库用户迁移指南
+
+### 思维模式转变
+
+从OLTP到OLAP的转变需要调整表设计思路：
+
+**传统OLTP设计**：
+
+```sql
+-- MySQL/PostgreSQL/Oracle风格
+CREATE TABLE orders (
+    order_id INT PRIMARY KEY AUTO_INCREMENT,
+    customer_id INT NOT NULL,
+    order_date DATETIME DEFAULT NOW(),
+    status VARCHAR(20) DEFAULT 'NEW',
+    FOREIGN KEY (customer_id) REFERENCES customers(id),
+    INDEX idx_date (order_date),
+    INDEX idx_customer (customer_id)
+);
+```
+
+**Lakehouse OLAP设计**：
+
+```sql
+-- 面向分析优化的设计
+CREATE TABLE orders (
+    order_id BIGINT IDENTITY(1),     -- 自增主键
+    customer_id INT NOT NULL,
+    order_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    status VARCHAR(20) DEFAULT 'NEW',
+    
+    -- 分析优化字段
+    order_year INT GENERATED ALWAYS AS (year(order_date)),
+    order_month INT GENERATED ALWAYS AS (month(order_date)),
+    order_day INT GENERATED ALWAYS AS (day(order_date)),
+    
+    -- 索引定义
+    INDEX bloom_customer (customer_id) BLOOMFILTER,
+    INDEX bloom_status (status) BLOOMFILTER
+) 
+PARTITIONED BY (order_year, order_month)  -- 按月分区
+CLUSTERED BY (customer_id) INTO 256 BUCKETS  -- 客户维度优化
+PROPERTIES (
+    'data_lifecycle' = '2555'  -- 7年数据保留
+);
+```
+
+### 数据类型映射
+
+| 传统数据库               | Lakehouse          | 迁移建议         |
+| ------------------- | ------------------ | ------------ |
+| INT AUTO\_INCREMENT | BIGINT IDENTITY(1) | 使用BIGINT避免溢出 |
+| DATETIME            | TIMESTAMP          | 统一时间类型       |
+| TEXT                | STRING             | 默认16MB，可调整   |
+| ENUM                | VARCHAR + CHECK    | 使用约束替代       |
+| JSON (MySQL)        | JSON               | 原生JSON支持     |
+| SERIAL (PG)         | BIGINT IDENTITY(1) | 完全兼容         |
+
+### 索引策略转换
+
+```sql
+-- 传统B-Tree索引 → 列式存储优化
+CREATE TABLE user_activity (
+    user_id BIGINT,
+    activity_time TIMESTAMP,
+    activity_type VARCHAR(50),
+    details JSON,
+    
+    -- 布隆过滤器替代B-Tree（点查询）
+    INDEX bloom_user (user_id) BLOOMFILTER,
+    
+    -- 倒排索引替代全文索引
+    INDEX inv_details (details) INVERTED PROPERTIES ('analyzer' = 'english'),
+    
+    -- 生成列优化时间查询
+    activity_date STRING GENERATED ALWAYS AS (date_format(activity_time, 'yyyy-MM-dd'))
+) 
+PARTITIONED BY (activity_date)  -- 时间分区加速范围查询
+CLUSTERED BY (user_id) INTO 128 BUCKETS;  -- 用户维度聚集
+```
+
+***
+
+## 高级特性详解
+
+### 1. 自增列（IDENTITY）
+
+```sql
+-- 完整示例：订单表with自增主键
+CREATE TABLE order_master (
+    order_id BIGINT IDENTITY(1000),  -- 从1000开始
+    order_no VARCHAR(50) NOT NULL,
+    customer_id BIGINT NOT NULL,
+    total_amount DECIMAL(18,2),
+    create_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+) COMMENT '订单主表';
+
+-- 注意事项：
+-- 1. 仅支持BIGINT类型
+-- 2. 不保证连续性（高并发下可能跳号）
+-- 3. 不支持ALTER TABLE添加
+```
+
+**2. 生成列（GENERATED ALWAYS AS）**
+
+```sql
+-- 时间维度自动生成
+CREATE TABLE sales_detail (
+    sale_time TIMESTAMP,
+    product_id INT,
+    quantity INT,
+    unit_price DECIMAL(10,2),
+    
+    -- 自动计算字段
+    total_amount DECIMAL(18,2) GENERATED ALWAYS AS (quantity * unit_price),
+    
+    -- 时间维度展开
+    sale_date STRING GENERATED ALWAYS AS (date_format(sale_time, 'yyyy-MM-dd')),
+    sale_year INT GENERATED ALWAYS AS (year(sale_time)),
+    sale_month INT GENERATED ALWAYS AS (month(sale_time)),
+    sale_week INT GENERATED ALWAYS AS (weekofyear(sale_time)),
+    sale_hour INT GENERATED ALWAYS AS (hour(sale_time))
+) 
+PARTITIONED BY (sale_date)  -- 可以用生成列作为分区
+COMMENT '销售明细表with自动计算字段';
+```
+
+**生成列使用限制**：
+
+* 生成列不能用于 `CLUSTERED BY` 或 `SORTED BY`
+* 主键表不能使用生成列作为分区键
+* 只支持确定性函数，不支持 `CURRENT_DATE`、`RANDOM` 等非确定性函数
+
+### 3. 默认值（DEFAULT）
+
+```sql
+-- 审计表设计
+CREATE TABLE audit_log (
+    log_id BIGINT IDENTITY(1),
+    table_name VARCHAR(100) NOT NULL,
+    operation VARCHAR(20) NOT NULL,
+    user_id VARCHAR(50) DEFAULT CURRENT_USER(),  -- 当前用户
+    operation_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP,  -- 当前时间
+    client_ip VARCHAR(50) DEFAULT '0.0.0.0',
+    status VARCHAR(20) DEFAULT 'SUCCESS',
+    details JSON
+) 
+PARTITIONED BY (date_format(operation_time, 'yyyy-MM-dd'))
+COMMENT '统一审计日志表';
+```
+
+### 4. 主键与唯一约束
+
+```sql
+-- CDC场景的主键表设计
+CREATE TABLE customer_snapshot (
+    customer_id BIGINT,
+    snapshot_date DATE,
+    customer_name VARCHAR(200),
+    customer_level VARCHAR(20),
+    total_purchase DECIMAL(18,2),
+    last_update TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    
+    -- 复合主键
+    PRIMARY KEY (customer_id, snapshot_date)
+) 
+PARTITIONED BY (snapshot_date)
+CLUSTERED BY (customer_id, snapshot_date) 
+SORTED BY (customer_id, snapshot_date) INTO 64 BUCKETS  -- 注意：主键表必须使用ASC排序
+COMMENT '客户快照表for CDC';
+```
+
+**主键表的重要限制**：
+
+* 主键列必须包含在 `CLUSTERED BY` 和 `SORTED BY` 中
+* `SORTED BY` 必须使用升序（ASC），不能使用降序（DESC）
+* 分区列必须是主键的子集
+* 如果使用生成列，不能将其作为主键表的分区列
+
+### 5. 复杂索引策略
+
+```sql
+-- 多维度查询优化表
+CREATE TABLE product_search (
+    product_id BIGINT PRIMARY KEY,
+    product_name VARCHAR(500),
+    description STRING,
+    category_path VARCHAR(200),
+    brand VARCHAR(100),
+    price DECIMAL(10,2),
+    tags ARRAY<STRING>,
+    attributes MAP<STRING, STRING>,
+    
+    -- 多种索引组合（注意：索引名必须全局唯一）
+    INDEX bloom_prod_brand (brand) BLOOMFILTER,  -- 品牌快速过滤
+    INDEX bloom_prod_category (category_path) BLOOMFILTER,  -- 类目过滤
+    INDEX inv_prod_name (product_name) INVERTED PROPERTIES ('analyzer' = 'chinese'),  -- 商品名搜索
+    INDEX inv_prod_desc (description) INVERTED PROPERTIES ('analyzer' = 'chinese')  -- 描述搜索
+)
+CLUSTERED BY (product_id) SORTED BY (product_id) INTO 128 BUCKETS  -- 主键表限制
+COMMENT '商品搜索优化表';
+```
+
+**索引命名最佳实践**：
+
+* 索引名必须在整个数据库中唯一
+* 建议使用 `表名_列名` 或 `idx_表名_列名` 格式
+* 避免使用过于通用的名称如 `idx_id`
+
+### 6. 向量索引（VECTOR）
+
+```sql
+-- 向量搜索场景表设计
+CREATE TABLE embeddings_search (
+    doc_id BIGINT PRIMARY KEY,
+    content STRING,
+    embedding VECTOR(512),  -- 512维向量，默认float类型
+    vec_small VECTOR(128),  -- 128维向量
+    vec_int VECTOR(int, 256),  -- 指定int类型的256维向量
+    
+    -- 向量索引
+    INDEX vec_idx (embedding) USING VECTOR PROPERTIES (
+        'scalar.type' = 'f32',
+        'distance.function' = 'cosine_distance',  -- 余弦距离
+        'm' = '16',  -- HNSW算法参数
+        'ef.construction' = '200'
+    )
+)
+CLUSTERED BY (doc_id) SORTED BY (doc_id) INTO 64 BUCKETS
+COMMENT '向量搜索优化表';
+```
+
+**向量类型使用限制**：
+
+* 不支持在ORDER BY或GROUP BY中使用
+* 支持的元素类型：tinyint、int、float（默认）
+* 可与数组类型相互转换
+
+***
+
+## 分区策略最佳实践
+
+### 1. 时间分区设计
+
+```sql
+-- 多粒度时间分区
+CREATE TABLE event_log (
+    event_id BIGINT,
+    event_time TIMESTAMP,
+    event_type VARCHAR(50),
+    event_data JSON,
+    
+    -- 多层分区字段生成
+    event_date STRING GENERATED ALWAYS AS (date_format(event_time, 'yyyy-MM-dd')),
+    event_hour INT GENERATED ALWAYS AS (hour(event_time))
+) 
+PARTITIONED BY (event_date, event_hour)  -- 双层分区
+COMMENT '事件日志表with小时级分区';
+
+-- 转换分区函数示例
+CREATE TABLE metric_data (
+    metric_time TIMESTAMP,
+    metric_name VARCHAR(100),
+    metric_value DOUBLE
+) 
+PARTITIONED BY (
+    days(metric_time)  -- 按天数分区（从1970-01-01开始）
+);
+```
+
+### 2. 业务维度分区
+
+```sql
+-- 多维度组合分区
+CREATE TABLE transaction_fact (
+    tx_id BIGINT IDENTITY(1),
+    tx_time TIMESTAMP,
+    region_code VARCHAR(10),
+    channel_code VARCHAR(10),
+    amount DECIMAL(18,2),
+    
+    tx_date STRING GENERATED ALWAYS AS (date_format(tx_time, 'yyyy-MM-dd'))
+) 
+PARTITIONED BY (tx_date, region_code, channel_code)  -- 三维分区
+CLUSTERED BY (tx_id) INTO 256 BUCKETS
+COMMENT '交易事实表with多维分区';
+```
+
+### 3. 分区数量控制
+
+```sql
+-- 合理控制分区粒度
+CREATE TABLE log_archive (
+    log_time TIMESTAMP,
+    log_level VARCHAR(10),
+    log_content STRING,
+    
+    -- 按月分区，避免过多分区
+    log_month STRING GENERATED ALWAYS AS (date_format(log_time, 'yyyy-MM'))
+) 
+PARTITIONED BY (log_month)
+PROPERTIES (
+    'data_lifecycle' = '1095'  -- 3年后自动清理
+);
+```
+
+***
+
+## 分桶优化指南
+
+### 1. 分桶数量选择
+
+```sql
+-- 分桶数量计算公式：总数据量 / 128MB~1GB
+
+-- 小表（<10GB）：少量分桶
+CREATE TABLE small_dim (
+    dim_id INT,
+    dim_name VARCHAR(100)
+) CLUSTERED BY (dim_id) INTO 8 BUCKETS;
+
+-- 中表（10GB~1TB）：适度分桶
+CREATE TABLE medium_fact (
+    fact_id BIGINT,
+    measure DECIMAL(18,4)
+) CLUSTERED BY (fact_id) INTO 128 BUCKETS;
+
+-- 大表（>1TB）：大量分桶
+CREATE TABLE large_fact (
+    id BIGINT,
+    data STRING
+) CLUSTERED BY (id) INTO 1024 BUCKETS;
+```
+
+### 2. 分桶键选择策略
+
+```sql
+-- JOIN优化：使用JOIN键作为分桶键
+CREATE TABLE order_items (
+    order_id BIGINT,
+    item_id INT,
+    quantity INT,
+    price DECIMAL(10,2)
+) CLUSTERED BY (order_id) INTO 256 BUCKETS;  -- 与orders表相同分桶
+
+CREATE TABLE orders (
+    order_id BIGINT,
+    customer_id INT,
+    order_date DATE
+) CLUSTERED BY (order_id) INTO 256 BUCKETS;  -- 相同分桶策略
+```
+
+### 3. 排序优化
+
+```sql
+-- SORTED BY加速范围查询
+CREATE TABLE time_series_data (
+    device_id VARCHAR(50),
+    metric_time TIMESTAMP,
+    metric_value DOUBLE
+) 
+CLUSTERED BY (device_id) 
+SORTED BY (metric_time DESC)  -- 最新数据优先

+FROM VOLUME my_volume 
+USING CSV OPTIONS ('header' = 'true');
+```
+
+#### 小量数据导入 - VALUES方式
+
+```sql
+-- ✅ 适用场景：少量数据（建议100行以内）
+INSERT INTO table_name VALUES 
+(1, 'data1'), (2, 'data2'), (3, 'data3');
+```
+
+**推荐方式的优势**：
+
+* 更高的导入性能和吞吐量
+* 更好的资源利用率
+* 支持事务性保证
+* 减少网络传输开销
+

+MAP('k1','v1','k2','v2')             -- MAP类型
+STRUCT(1, 'hello', 3.14)             -- STRUCT类型
+```
+
+### 1.4 INSERT OVERWRITE行为
+
+* **分区表**：覆盖匹配的分区数据
+* **非分区表**：覆盖整表数据
+* **前提条件**：目标表必须存在
+
+### 1.5 分区操作限制
+
+* **分区数量上限**：单任务最多2048个分区
+* **超限处理**：分批导入或优化分区策略
+* **建议检查**：大批量导入前统计分区数量
+
+### 1.6 列映射和类型匹配
+
+* **显式指定**：建议明确指定目标列名
+* **类型匹配**：确保数据类型精确对应
+* **NULL处理**：未指定列将填入NULL值
+
+## 2. UPDATE语句规范
+
+### 2.1 基本语法
+
+```sql
+UPDATE target_table 
+SET column_name1 = new_value1 [, column_name2 = new_value2, ...] 
+[ WHERE condition ] 
+[ORDER BY ...] 
+[LIMIT row_count]
+```
+
+### 2.2 WHERE条件要求
+
+* **必要性**：强烈建议使用WHERE条件限制更新范围
+* **精确性**：使用精确条件避免误操作
+* **复杂查询**：支持子查询和表达式

+* **回滚准备**：准备数据恢复方案
+
+## 3. DELETE语句规范
+
+### 3.1 基本语法
+
+```sql
+DELETE FROM table_name WHERE condition;
+```
+
+### 3.2 安全要求
+
+* **WHERE条件**：避免省略WHERE导致全表删除
+* **条件验证**：删除前验证条件的准确性
+* **备份保护**：重要数据删除前备份
+
+### 3.3 性能优化
+
+* **索引利用**：WHERE条件充分利用索引

+
+## 4. MERGE INTO语句规范
+
+### 4.1 基本语法
+
+```sql
+MERGE INTO target_table USING source_table ON merge_condition 
+{ WHEN MATCHED [AND matched_condition] THEN matched_action |
+  WHEN NOT MATCHED [AND not_matched_condition] THEN not_matched_action } ...
+```
+
+### 4.2 语句顺序要求
+
+**WHEN MATCHED 必须在 WHEN NOT MATCHED 之前**
+
+```sql
+-- ✅ 正确顺序
+MERGE INTO target USING source ON target.key = source.key 
+WHEN MATCHED THEN UPDATE SET target.col1 = source.col1
+WHEN NOT MATCHED THEN INSERT (col1, col2) VALUES (source.col1, source.col2);
+```
+
+### 4.3 匹配条件设计
+
+* **唯一性**：确保ON条件产生一对一匹配
+* **确定性**：避免源表多行匹配目标表同一行

+
+### 基础JOIN语法
+
+```sql
+-- 标准INNER JOIN
+SELECT e.emp_name, d.dept_name
+FROM employees e
+INNER JOIN departments d ON e.dept_id = d.dept_id;
+
+-- LEFT JOIN保证左表完整性
+SELECT e.emp_name, d.dept_name
+FROM employees e
+LEFT JOIN departments d ON e.dept_id = d.dept_id;
+
+-- SEMI JOIN进行存在性检查
+SELECT e.emp_name, e.salary
+FROM employees e
+SEMI JOIN departments d ON e.dept_id = d.dept_id;
+
+-- ANTI JOIN识别孤立数据
+SELECT e.emp_name, e.dept_id
+FROM employees e
+ANTI JOIN departments d ON e.dept_id = d.dept_id;
+```

+
+## 性能优化策略
+
+### MAPJOIN广播优化
+
+MAPJOIN 是云器 Lakehouse 的核心优化特性，通过将小表广播到所有计算节点，显著提升JOIN性能。
+
+**优化原理**：
+- 消除昂贵的 Shuffle 操作
+- 缓解数据倾斜问题
+- 提升查询执行速度
+
+```sql
+-- 单表广播优化
+SELECT /*+ MAPJOIN(departments) */ 
+    e.emp_name, d.dept_name, d.budget
+FROM employees e
+JOIN departments d ON e.dept_id = d.dept_id;
+
+-- 多表广播优化
+SELECT /*+ MAPJOIN(employees, departments) */
+    o.order_id, e.emp_name, d.dept_name
+FROM orders o
+JOIN employees e ON o.emp_id = e.emp_id
+JOIN departments d ON e.dept_id = d.dept_id;
+```
+
+**使用建议**：
+- 小表大小建议控制在 1GB 以内
+- 适用于维度表与事实表的关联
+- 优先考虑小表广播，而非大表 JOIN 大表
+
+### SORTMERGEJOIN排序合并优化
+
+适用于大表与大表的 JOIN 场景，特别是数据已按 JOIN 键排序的情况。
+
+```sql
+-- 大表JOIN优化
+SELECT /*+ SORTMERGEJOIN(table1, table2) */
+    t1.customer_id, t2.order_amount
+FROM large_customer_table t1
+JOIN large_order_table t2 ON t1.customer_id = t2.customer_id;
+```
+
+### 查询结构优化
+
+遵循“过滤-连接-聚合”的最佳实践模式：
+
+```sql
+-- 推荐的查询结构
+WITH filtered_facts AS (
+    SELECT fact_id, dimension_id, amount, date_key
+    FROM fact_table
+    WHERE date_key >= '20240101'          -- 先过滤
+      AND amount > 1000
+),
+enriched_data AS (
+    SELECT /*+ MAPJOIN(dim_table) */
+        f.fact_id, f.amount, d.category
+    FROM filtered_facts f
+    JOIN dim_table d ON f.dimension_id = d.dimension_id  -- 后连接
+)
+SELECT 
+    category,
+    COUNT(*) as record_count,
+    SUM(amount) as total_amount                          -- 最后聚合
+FROM enriched_data
+GROUP BY category;
+```
+

+
+## Spark用户迁移指南
+
+### 直接迁移的技能
+
+Spark用户可以无缝使用以下功能：
+
+```sql
+-- DataFrame广播JOIN → MAPJOIN提示
+SELECT /*+ MAPJOIN(small_table) */
+    l.order_id, s.product_name
+FROM large_orders l
+JOIN small_products s ON l.product_id = s.product_id;
+
+-- 窗口函数完全兼容
+SELECT 
+    emp_name,
+    salary,
+    ROW_NUMBER() OVER (PARTITION BY dept_id ORDER BY salary DESC) as rank
+FROM employees;
+
+-- 复杂数据类型处理
+SELECT 
+    user_id,
+    event_array[0] as first_event,           -- 数组索引从0开始
+    size(event_array) as event_count,
+    explode(event_array) as individual_event -- 直接使用，无需LATERAL VIEW
+FROM user_events;
+```
+
+### 语法调整要点
+
+**1. 数组展开语法简化**
+
+```sql
+-- Spark语法（不支持）
+SELECT user_id, tag
+FROM users LATERAL VIEW explode(tags) t AS tag;
+
+-- Lakehouse语法
+SELECT user_id, explode(tags) as tag
+FROM users;
+```
+
+**2. 结构体操作保持一致**
+
+```sql
+-- Spark兼容的结构体操作
+WITH customer_profiles AS (
+    SELECT 
+        customer_id,
+        named_struct(
+            'name', customer_name,
+            'contact', named_struct('email', email, 'phone', phone)
+        ) as profile
+    FROM customers
+)
+SELECT 
+    customer_id,
+    profile.name as customer_name,
+    profile.contact.email as email
+FROM customer_profiles;
+```
+
+### 数据倾斜处理策略
+
+```sql
+-- 盐值JOIN解决数据倾斜
+WITH salted_large AS (
+    SELECT *, 
+           CONCAT(join_key, '_', ABS(HASH(join_key) % 10)) as salted_key
+    FROM large_table
+),
+salted_small AS (
+    SELECT *, 
+           CONCAT(join_key, '_', sequence) as salted_key
+    FROM small_table 
+    CROSS JOIN (SELECT EXPLODE(SEQUENCE(0, 9)) as sequence)
+)
+SELECT l.data, s.info
+FROM salted_large l
+JOIN salted_small s ON l.salted_key = s.salted_key;
+```
+
+---
+
+## Hive用户迁移指南
+
+### 概念延续与性能升级
+
+Hive用户熟悉的分区表和批处理概念在Lakehouse中得到保留和增强：
+
+```sql
+-- 分区裁剪概念保持一致
+SELECT /*+ MAPJOIN(dim_table) */
+    fact.order_id, dim.product_name
+FROM fact_orders fact
+JOIN dim_products dim ON fact.product_id = dim.product_id
+WHERE fact.dt = '2024-06-01';           -- 分区字段过滤
+```
+
+### MapReduce到列式计算的跃升
+
+```sql
+-- Hive多阶段Job → Lakehouse一体化查询
+WITH order_aggregation AS (
+    SELECT 
+        customer_id,
+        SUM(amount) as total_amount,
+        COUNT(*) as order_count
+    FROM orders 
+    WHERE order_date >= '2024-01-01'
+    GROUP BY customer_id
+)
+SELECT /*+ MAPJOIN(customers) */
+    c.customer_name,
+    a.total_amount,
+    a.order_count
+FROM order_aggregation a
+JOIN customers c ON a.customer_id = c.customer_id
+WHERE a.total_amount > 10000;
+```
+
+### MAPJOIN功能增强
+
+```sql
+-- Hive手动控制 → Lakehouse智能优化
+SELECT /*+ MAPJOIN(employees, departments) */  -- 支持多表广播
+    o.order_id, e.emp_name, d.dept_name
+FROM orders o
+JOIN employees e ON o.emp_id = e.emp_id
+JOIN departments d ON e.dept_id = d.dept_id;
+```
+
+---
+
+## MaxCompute用户迁移指南
+
+### 语法兼容性
+
+MaxCompute用户可以直接使用熟悉的语法：
+
+```sql
+-- MAPJOIN语法直接兼容
+SELECT /*+ MAPJOIN(small_table) */
+    large.order_id, small.product_name
+FROM large_orders large
+JOIN small_products small ON large.product_id = small.product_id;
+
+-- 分区查询方式保持一致
+SELECT * FROM orders 
+WHERE order_date = '2024-06-01'
+  AND status = 'completed';
+```
+
+### 函数迁移映射
+
+```sql
+-- 时间函数对应关系
+SELECT 
+    order_id,
+    CURRENT_TIMESTAMP() as process_time,        -- MaxCompute: GETDATE()
+    DATE_FORMAT(order_date, 'yyyy-MM') as month -- 语法兼容
+FROM orders;
+```
+
+### SEMI JOIN优化
+
+```sql
+-- EXISTS查询 → SEMI JOIN性能优化
+SELECT a.customer_id, a.customer_name
+FROM customers a
+SEMI JOIN orders b ON a.customer_id = b.customer_id;
+```
+
+---
+
+## Snowflake用户迁移指南
+
+### 云原生特性对应
+
+```sql
+-- 自动优化 → 显式优化控制
+SELECT /*+ MAPJOIN(customer_dim, product_dim) */
+    cd.customer_name, pd.product_name, sf.sales_amount
+FROM sales_fact sf
+JOIN customer_dim cd ON sf.customer_id = cd.customer_id
+JOIN product_dim pd ON sf.product_id = pd.product_id
+WHERE sf.sale_date >= '2024-06-01';
+```
+
+### 资源管理对比
+
+- **Snowflake WAREHOUSE** → **Lakehouse VCLUSTER**
+- **自动扩缩容** → **弹性计算资源**
+- **按需付费** → **按使用量计费**
+
+### 历史数据查询
+
+<= '2024-06-01 23:59:59';
+```
+
+---
+
+## 传统数据库用户迁移指南
+
+### 思维模式转换
+
+**从OLTP到OLAP的架构升级**
+
+```sql
+-- OLTP思维：单条记录查询
+-- 转换为
+-- OLAP思维：批量分析查询
+
+SELECT /*+ MAPJOIN(customers) */
+    c.customer_segment,
+    COUNT(*) as order_count,
+    AVG(o.order_amount) as avg_amount,
+    SUM(o.order_amount) as total_amount
+FROM customers c
+JOIN orders o ON c.customer_id = o.customer_id
+WHERE o.order_date >
+
+### 索引策略调整
+
+```sql
+-- 传统索引 → 列式存储 + 布隆过滤器
+CREATE BLOOMFILTER INDEX idx_customer_bloom 
+ON TABLE orders(customer_id);
+
+-- 查询自动应用优化
+SELECT /*+ MAPJOIN(customers) */
+    c.customer_name, COUNT(o.order_id) as order_count
+FROM customers c
+JOIN orders o ON c.customer_id = o.customer_id
+GROUP BY c.customer_name;
+```
+
+### 事务处理转换
+
+```sql
+-- 传统事务 → 批量MERGE操作
+MERGE INTO customers c
+USING (
+    SELECT customer_id
+    FROM order_summary 
+    WHERE total_amount > 50000
+) high_value ON c.customer_id = high_value.customer_id
+WHEN MATCHED THEN UPDATE SET status = 'premium';
+```
+
+---
+
+## JOIN条件与语法规范
+
+### 支持的条件语法
+
+```sql
+-- ON条件表达式
+SELECT * FROM table1 t1
+JOIN table2 t2 ON t1.id = t2.id;
+
+-- USING简化语法
+SELECT * FROM table1 t1
+JOIN table2 t2 USING (id);
+
+-- 复合条件
+SELECT * FROM orders o
+JOIN employees e ON o.emp_id = e.emp_id 
+                 AND o.order_date >= e.hire_date;
+```
+
+### 语法限制与替代方案
+
+**JOIN 条件中避免使用子查询**
+
+```sql
+-- 不推荐的写法
+SELECT e.emp_name
+FROM employees e
+JOIN departments d ON e.dept_id = (
+    SELECT dept_id FROM departments WHERE dept_name = 'Engineering'
+);
+
+-- 推荐的替代方案
+SELECT e.emp_name
+FROM employees e
+JOIN departments d ON e.dept_id = d.dept_id
+WHERE d.dept_name = 'Engineering';
+
+-- 或使用CTE
+WITH target_dept AS (
+    SELECT dept_id FROM departments WHERE dept_name = 'Engineering'
+)
+SELECT e.emp_name
+FROM employees e
+JOIN target_dept t ON e.dept_id = t.dept_id;
+```
+
+---
+
+## 数据类型与NULL值处理
+
+### NULL值显示特性
+
+云器Lakehouse中不同数据类型的NULL值具有特定的显示格式：
+
+<- STRING类型NULL正常显示
+|          | nan     | HR        | <- 数值类型NULL显示为"nan"
++----------+---------+-----------+
+*/
+```
+
+**显示规律**：
+- **字符类型**（STRING、VARCHAR）：NULL显示为空
+- **数值类型**（INT、DOUBLE、DECIMAL）：NULL显示为"nan"
+- **时间类型**（DATE、TIMESTAMP）：NULL显示为"NaT"
+- **逻辑判断**：IS NULL和IS NOT NULL在所有类型上正常工作
+
+### NULL值安全处理
+
+```sql
+-- 安全的NULL值处理
+SELECT 
+    emp_name,
+    CASE 
+        WHEN salary IS NULL OR CAST(salary AS STRING) = 'nan' 
+        THEN 0.0 
+        ELSE salary 
+    END as safe_salary,
+    COALESCE(dept_name, 'Unknown Department') as safe_dept_name
+FROM employees e
+LEFT JOIN departments d ON e.dept_id = d.dept_id;
+```
+
+---
+
+## 复杂JOIN场景
+
+### 多表关联分析
+
+```sql
+-- 典型的维度建模查询
+SELECT /*+ MAPJOIN(dim_customer, dim_product, dim_date) */
+    dd.year,
+    dd.quarter,
+    dc.customer_tier,
+    dp.product_line,
+    COUNT(*) as transaction_count,
+    SUM(ft.amount) as total_revenue,
+    AVG(ft.amount) as avg_transaction_value
+FROM fact_transactions ft
+JOIN dim_customer dc ON ft.customer_id = dc.customer_id
+JOIN dim_product dp ON ft.product_id = dp.product_id  
+JOIN dim_date dd ON ft.date_id = dd.date_id
+WHERE dd.year >
+
+### 层次化数据处理
+
+```sql
+-- 组织架构多级查询
+WITH employee_hierarchy AS (
+    -- 第一级：高级管理层
+    SELECT employee_id, employee_name, 1 as level
+    FROM employees WHERE manager_id IS NULL
+    
+    UNION ALL
+    
+    -- 第二级：中层管理
+    SELECT e.employee_id, e.employee_name, 2 as level
+    FROM employees e
+    JOIN employees m ON e.manager_id = m.employee_id
+    WHERE m.manager_id IS NULL
+    
+    UNION ALL
+    
+    -- 第三级：基层员工
+    SELECT e.employee_id, e.employee_name, 3 as level
+    FROM employees e
+    JOIN employees m1 ON e.manager_id = m1.employee_id
+    JOIN employees m2 ON m1.manager_id = m2.employee_id
+    WHERE m2.manager_id IS NULL
+)
+SELECT level, COUNT(*) as employee_count
+FROM employee_hierarchy
+GROUP BY level
+ORDER BY level;
+```
+
+### 时间序列JOIN
+
+```sql
+-- 时间窗口关联分析
+SELECT o.order_id, l.line_item_id, o.order_date, l.ship_date
+FROM orders o
+JOIN line_items l ON o.order_id = l.order_id
+                  AND o.order_date BETWEEN l.ship_date - INTERVAL '5' DAY 
+                                       AND l.ship_date + INTERVAL '5' DAY
+WHERE o.order_date >= '2024-01-01';
+```
+
+---
+
+## 性能调优实践
+
+### 查询优化检查清单
+
+#### 1. JOIN策略选择
+
+```sql
+-- 小表 × 大表：MAPJOIN优先
+SELECT /*+ MAPJOIN(dim_table) */
+    fact.*, dim.dimension_name
+FROM fact_table fact
+JOIN dim_table dim ON fact.dim_id = dim.dim_id;
+
+-- 大表 × 大表：SORTMERGEJOIN
+SELECT /*+ SORTMERGEJOIN(table1, table2) */
+    t1.*, t2.*
+FROM large_table1 t1
+JOIN large_table2 t2 ON t1.join_key = t2.join_key;
+```
+
+#### 2. 谓词下推优化
+
+```sql
+-- 将过滤条件前置
+WITH filtered_base AS (
+    SELECT customer_id, order_id, amount
+    FROM orders
+    WHERE order_date >= '2024-01-01'      -- 过滤前置
+      AND status = 'completed'
+)
+SELECT /*+ MAPJOIN(customers) */
+    c.customer_name, f.amount
+FROM filtered_base f
+JOIN customers c ON f.customer_id = c.customer_id;
+```
+
+#### 3. 列裁剪策略
+
+```sql
+-- 明确指定所需列
+SELECT customer_id, customer_name, order_count
+FROM customer_summary
+WHERE registration_date >= '2024-01-01';
+
+-- 使用EXCEPT排除不必要的列
+SELECT * EXCEPT(internal_notes, created_by, updated_by)
+FROM customer_details;
+```
+
+### 分页查询策略
+
+#### 基于游标的高效分页
+
+```sql
+-- 推荐的分页方式
+SELECT customer_id, order_id, order_date, amount
+FROM orders 
+WHERE customer_id > :last_customer_id  -- 游标位置
+   OR (customer_id = :last_customer_id AND order_id > :last_order_id)
+ORDER BY customer_id, order_id
+LIMIT 1000;
+```
+
+#### 范围分区分页
+
+```sql
+-- 基于业务逻辑的分区处理
+SELECT * FROM orders 
+WHERE order_date >= '2024-06-01'
+  AND order_date < '2024-06-02'  -- 按天分批处理
+ORDER BY order_id;
+```
+
+---
+
+## 最佳实践总结
+
+### 通用优化原则
+
+1. **小表广播优先**：维度表与事实表关联首选MAPJOIN
+2. **过滤条件前置**：在JOIN之前完成数据过滤
+3. **选择精确JOIN类型**：根据业务需求选择最合适的JOIN类型
+4. **避免深度分页**：使用游标分页替代OFFSET分页
+5. **监控执行计划**：关注查询性能和资源使用

+## 迁移用户指导
+
+如果您习惯了Spark、MySQL、PostgreSQL或其他数据库系统，本节将帮助您快速适应云器Lakehouse并避免常见错误。我们理解切换到新系统的挑战，因此准备了这份详细的对比指南。
+
+### 🔄 **如果您习惯了Spark SQL**
+
+#### ✅ **可以直接复用的技能**
+
+```sql
+-- 以下Spark SQL代码可以直接在Lakehouse中运行
+SELECT customer_id, COUNT(*), SUM(amount)
+FROM orders 
+WHERE order_date >= '2024-01-01'
+GROUP BY customer_id
+HAVING COUNT(*) > 5;
+
+-- 窗口函数完全兼容
+SELECT 
+    employee_id,
+    salary,
+    ROW_NUMBER() OVER (PARTITION BY department ORDER BY salary DESC) as rank
+FROM employees;
+```
+
+#### ⚠️ **需要调整的语法**
+
+**1. LATERAL VIEW语法**
+
+```sql
+-- ❌ Spark语法（不支持）
+SELECT user_id, event 
+FROM user_events LATERAL VIEW explode(event_array) AS event;
+
+-- ✅ Lakehouse语法
+SELECT user_id, explode(event_array) as event 
+FROM user_events;
+```
+
+**2. 正则表达式函数**
+
+```sql
+-- ❌ Spark语法（不支持）
+WHERE regexp_like(column_name, 'pattern')
+
+-- ✅ Lakehouse替代方案
+WHERE regexp_extract(column_name, 'pattern', 0) != ''
+-- 或者使用LIKE
+WHERE column_name LIKE '%pattern%'
+```
+
+**3. 类型转换差异**
+
+```sql
+-- ⚠️ 注意：转换失败时返回特殊值而非NULL
+SELECT 
+    TRY_CAST('abc' AS INT) as result,  -- 返回nan，不是NULL
+    -- 安全转换方式
+    CASE 
+        WHEN TRY_CAST('abc' AS INT) IS NOT NULL 
+             AND CAST(TRY_CAST('abc' AS INT) AS STRING) != 'nan'
+        THEN TRY_CAST('abc' AS INT)
+        ELSE 0
+    END as safe_result;
+```
+
+**4. NULL值显示特性**
+
+```sql
+-- ⚠️ 数值类型和时间类型的NULL有特殊显示格式
+SELECT 
+    LAG(order_date) OVER (...) as prev_date,     -- 时间类型NULL显示为"NaT"
+    LAG(customer_id) OVER (...) as prev_id,      -- 数值类型NULL显示为"nan"
+    CASE 
+        WHEN LAG(order_date) OVER (...) IS NULL  -- 但IS NULL判断仍然有效
+        THEN 'First Record'
+        ELSE 'Has Previous'
+    END as status
+FROM orders;
+```
+
+#### **复杂数据类型高级应用**
+
+```sql
+-- Spark SQL数组操作（直接兼容）

+```
+
+### 🗄️ **如果您习惯了MySQL/PostgreSQL**
+
+#### ✅ **可以直接复用的技能**
+
+```sql
+-- 标准SQL查询完全兼容
+SELECT c.customer_name, COUNT(o.order_id) as order_count
+FROM customers c
+LEFT JOIN orders o ON c.customer_id = o.customer_id
+WHERE c.registration_date >= '2024-01-01'
+GROUP BY c.customer_id, c.customer_name;
+```
+
+#### 🔌 **MySQL用户的额外选择：MySQL协议支持**
+
+【**预览发布】云器Lakehouse支持MySQL协议连接**！
+
+```bash
+# ✅ 可以使用熟悉的MySQL连接方式
+# MySQL 8.x 连接方式
+jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com:3306/public?useSSL=true
+
+# MySQL 5.x 连接方式  
+jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com:3306/public?useSSL=false
+
+# 命令行连接
+mysql -h cn-shanghai-alicloud-mysql.api.clickzetta.com -P 3306 -u username -p database_name
+```
+
+**📊 主要用途**
+
+* **BI报表工具**：无法使用自定义JDBC驱动的报表工具
+* **遗留系统集成**：现有MySQL客户端应用快速接入
+* **开发工具兼容**：使用熟悉的MySQL管理工具
+
+**⚠️ 重要限制**
+
+* **语法仍为Lakehouse**：虽然协议兼容，但SQL语法需使用Lakehouse标准
+* **数据类型限制**：不支持MySQL特有类型（mediumint、text、blob、enum等）
+* **功能限制**：不支持mysqldump、LOAD等MySQL特有命令
+
+```sql
+-- ❌ MySQL特有语法不支持
+CREATE TABLE test (col MEDIUMINT);  -- 报错
+SELECT CAST(value AS TEXT);         -- 报错
+
+-- ✅ 使用Lakehouse对应类型
+CREATE TABLE test (col INT);        -- 正确
+SELECT CAST(value AS STRING);       -- 正确
+```
+
+**💡 选择建议**
+
+* **优先推荐**：使用Lakehouse原生驱动获得完整功能
+* **兼容场景**：无法使用原生驱动时选择MySQL协议
+
+#### ⚠️ **关键差异与工具限制**
+
+**1. 查询结果返回的工具限制**
+
+> 🎯 **核心理念**：查询返回的数据量往往受到您使用的工具或客户端限制，而非数据库引擎本身的限制。
+
+| 工具/客户端                      | 查询结果限制   | 适用场景     | 突破方案          |
+| --------------------------- | -------- | -------- | ------------- |
+| **Lakehouse Studio Web UI** | 最大10000行 | 数据探索、调试  | 添加WHERE条件过滤   |
+| **JDBC客户端**                 | 无硬性限制\*  | 应用开发、ETL | 分批处理、流式读取     |
+| **Python SDK**              | 无硬性限制\*  | 数据科学、脚本  | 分批处理、pandas分块 |
+| **BI工具**                    | 各工具不同    | 报表展示     | 查阅具体工具文档      |
+| **命令行工具**                   | 内存/配置限制  | 数据导出     | 调整配置或分批导出     |
+
+\*注：无硬性限制指SQL引擎层面无限制，但仍受内存、网络等资源限制。
+
+**2. 分页策略选择**
+
+```sql
+-- 📱 Web UI 数据探索策略（受10000行限制）
+SELECT customer_id, order_count, total_amount
+FROM customer_summary
+WHERE registration_date >= '2024-01-01'  -- 先过滤
+  AND customer_type = 'premium'
+ORDER BY total_amount DESC
+LIMIT 100;  -- 小批量查看
+
+-- 💻 编程接口大数据处理策略（无硬性限制）
+WITH batch_data AS (
+    SELECT customer_id, order_id, amount
+    FROM orders 
+    WHERE order_date = '2024-06-01'
+      AND customer_id BETWEEN :start_id AND :end_id  -- 批次范围
+)
+SELECT * FROM batch_data;
+
+-- 🔄 推荐：基于游标的分页（适用所有工具）
+SELECT customer_id, order_id, order_date, amount
+FROM orders 
+WHERE customer_id > :last_customer_id  -- 游标分页
+  AND order_date >= '2024-01-01'
+ORDER BY customer_id, order_id
+LIMIT 1000;  -- 适中的批次大小
+```
+
+**3. 字符串函数兼容性**
+
+```sql
+-- ✅ MySQL风格函数大多兼容
+SELECT 
+    SUBSTRING(name, 1, 5) as substr_mysql,    -- 支持
+    SUBSTR(name, 1, 5) as substr_standard,    -- 支持
+    CONCAT_WS(',', field1, field2) as concat_ws,  -- 支持
+    CONCAT(field1, ',', field2) as concat_std     -- 支持
+FROM users;
+```
+
+**4. 索引概念差异**
+
+```sql
+-- ❌ 传统数据库思维
+CREATE INDEX idx_name ON table(column);  -- 期望立即生效
+
+-- ✅ Lakehouse正确做法
+CREATE BLOOMFILTER INDEX idx_name ON TABLE table(column);  -- 仅对新数据生效
+-- 如需对已有数据生效（仅部分索引类型支持）
+BUILD INDEX idx_name ON table;
+```
+
+**5. 事务和锁定**
+
+```sql
+-- ⚠️ Lakehouse不支持传统事务语法
+-- ❌ 不支持
+BEGIN TRANSACTION;
+UPDATE products SET price = price * 1.1;
+COMMIT;
+
+-- ✅ 使用批量更新或MERGE语句
+MERGE INTO products p
+USING (SELECT product_id, price * 1.1 as new_price FROM products) src
+ON p.product_id = src.product_id
+WHEN MATCHED THEN UPDATE SET price = src.new_price;
+```
+
+### 📊 **列式存储优化思维**
+
+#### **传统行式 vs 列式存储**
+
+```sql
+-- ❌ 行式数据库思维：避免SELECT *
+SELECT * FROM large_table WHERE id = 123;
+
+-- ✅ 列式存储优化：明确指定列
+SELECT customer_id, order_amount, order_date 
+FROM large_table 
+WHERE id = 123;
+
+-- 💡 列式存储的优势
+SELECT 
+    product_category,
+    AVG(price) as avg_price,  -- 只读取price列，性能优异
+    COUNT(*) as product_count
+FROM products 
+GROUP BY product_category;
+```
+
+#### **分区概念理解**
+
+```sql
+-- 💡 分区表查询优化
+-- ✅ 正确：直接使用分区字段
+SELECT * FROM orders 
+WHERE order_date >= '2024-06-01' 
+  AND order_date <= '2024-06-30';
+
+-- ❌ 错误：对分区字段使用函数
+SELECT * FROM orders 
+WHERE YEAR(order_date) = 2024;  -- 无法利用分区裁剪
+```
+
+### 🚨 **常见错误和解决方案**
+
+#### **1. 数据类型选择错误**
+
+```sql
+-- ❌ 错误选择：JSON数据存储为字符串
+CREATE TABLE user_profiles (
+    user_id INT,
+    profile_data STRING  -- 需要类型转换才能使用JSON函数
+);
+
+-- ✅ 正确选择：使用原生JSON类型
+CREATE TABLE user_profiles (
+    user_id INT,
+    profile_data JSON    -- 直接支持JSON函数，性能更好
+);
+
+-- 查询语法对比
+-- STRING类型：需要转换
+SELECT user_id, json_extract_string(CAST(profile_data AS JSON), '$.age') as age
+FROM user_profiles_string;
+
+-- JSON类型：直接使用
+SELECT user_id, json_extract_string(profile_data, '$.age') as age
+FROM user_profiles_json;
+```
+
+#### **2. JOIN优化误区**
+
+```sql
+-- ❌ 传统数据库思维：大表在左
+SELECT l.*, s.name
+FROM large_table l
+JOIN small_table s ON l.id = s.id;
+
+-- ✅ Lakehouse优化：使用MAPJOIN提示
+SELECT /*+ MAPJOIN(small_table) */ l.*, s.name
+FROM large_table l
+JOIN small_table s ON l.id = s.id;
+```
+
+#### **3. 聚合查询优化**
+
+```sql
+-- ❌ 低效：多次扫描大表
+SELECT 
+    (SELECT COUNT(*) FROM large_table WHERE status = 'active') as active_count,
+    (SELECT COUNT(*) FROM large_table WHERE status = 'inactive') as inactive_count;
+
+-- ✅ 高效：一次扫描
+SELECT 
+    SUM(CASE WHEN status = 'active' THEN 1 ELSE 0 END) as active_count,
+    SUM(CASE WHEN status = 'inactive' THEN 1 ELSE 0 END) as inactive_count
+FROM large_table;
+```
+
+### 💡 **快速适应建议**
+
+#### **1. 优先使用的功能**
+
+* **JSON数据类型**：替代字符串存储半结构化数据
+* **VECTOR数据类型**：原生支持向量搜索
+* **分区表**：按时间或业务维度分区
+* **列式索引**：BLOOMFILTER、INVERTED、VECTOR
+* **MySQL协议连接**：无法使用原生驱动时的兼容选择
+
+#### **2. 性能优化习惯**
+
+```sql
+-- 好习惯：分区+列选择+索引
+SELECT customer_id, order_amount
+FROM orders 
+WHERE order_date >= '2024-06-01'     -- 分区裁剪
+  AND customer_type = 'premium'      -- 布隆过滤器索引
+  AND match_any(description, '手机', map('analyzer', 'chinese'))  -- 全文索引
+ORDER BY order_amount DESC
+LIMIT 100;
+```
+
+#### **3. 避免的反模式**
+
+```sql
+-- ❌ 避免的模式
+-- 1. 在分区字段上使用函数
+WHERE YEAR(partition_date) = 2024
+
+-- 2. 过度使用SELECT *
+SELECT * FROM large_table
+
+-- 3. 忽略数据类型优化
+profile_json STRING  -- 应该用JSON类型
+
+-- 4. 忽略工具限制的深度分页（Web UI）
+-- 在Studio中查询大量数据时没有添加过滤条件
+
+-- 5. 大表全量排序分页
+SELECT * FROM huge_table ORDER BY random_column LIMIT 100 OFFSET 5000  -- 性能极差
+```

+
+## 基本语法
+
+### SELECT语句结构
+
+Lakehouse SELECT语句遵循标准SQL语法，支持完整的查询功能：
+
+```sql
+SELECT [ALL | DISTINCT] select_expr [, select_expr ...]
+[FROM table_reference [, table_reference ...]]
+[WHERE where_condition]
+[GROUP BY grouping_element [, grouping_element ...]]
+[HAVING having_condition]
+[ORDER BY sort_item [, sort_item ...]]
+[LIMIT row_count]
+```
+
+### 基本查询示例
+
+```sql
+-- 基础查询
+SELECT 
+    customer_id,
+    customer_name,
+    registration_date,
+    total_orders
+FROM customers
+WHERE registration_date >= '2024-01-01'
+ORDER BY total_orders DESC
+LIMIT 100;
+
+-- 聚合查询
+SELECT 
+    product_category,
+    COUNT(*) as product_count,
+    AVG(price) as avg_price,
+    SUM(sales_amount) as total_sales
+FROM products
+GROUP BY product_category
+HAVING COUNT(*) > 10;
+```
+
+### 增强语法特性
+
+#### EXCEPT子句
+
+Lakehouse提供了EXCEPT子句用于排除指定列：
+
+```sql
+-- 排除敏感字段
+SELECT * EXCEPT(password, credit_card, ssn)
+FROM user_accounts;
+
+-- 排除多个字段
+SELECT * EXCEPT(internal_id, created_by, updated_by)
+FROM public_data;
+```

+
+## 数据类型系统
+
+### 核心数据类型
+
+| 类型分类 | 数据类型                           | 说明           | 示例                                            |
+| ---- | ------------------------------ | ------------ | --------------------------------------------- |
+| 数值类型 | TINYINT, SMALLINT, INT, BIGINT | 整数类型         | `SELECT 123::INT`                             |
+|      | FLOAT, DOUBLE                  | 浮点数类型        | `SELECT 3.14::DOUBLE`                         |
+|      | DECIMAL(p,s)                   | 精确数值类型       | `SELECT 999.99::DECIMAL(10,2)`                |
+| 字符类型 | STRING                         | 变长字符串，最大16MB | `SELECT 'Hello'::STRING`                      |
+|      | VARCHAR(n), CHAR(n)            | 定长/变长字符串     | `SELECT 'Text'::VARCHAR(50)`                  |
+| 日期时间 | DATE                           | 日期类型         | `SELECT '2024-06-01'::DATE`                   |
+|      | TIMESTAMP\_LTZ                 | 带时区时间戳       | `SELECT CURRENT_TIMESTAMP()`                  |
+|      | TIMESTAMP\_NTZ                 | 无时区时间戳       | `SELECT '2024-06-01 12:00:00'::TIMESTAMP_NTZ` |
+| 布尔类型 | BOOLEAN                        | 布尔值          | `SELECT true::BOOLEAN`                        |
+| 二进制  | BINARY                         | 二进制数据        | `SELECT X'48656C6C6F'::BINARY`                |
+
+### 复杂数据类型
+
+#### ARRAY类型
+
+```sql
+-- 创建和操作数组
+SELECT 
+    array(1, 2, 3, 4, 5) as numbers,
+    array('apple', 'banana', 'orange') as fruits,
+    array_contains(array(1, 2, 3), 2) as contains_check,
+    size(array(1, 2, 3, 4)) as array_length;
+
+-- 数组访问和处理
+WITH data AS (
+    SELECT array('a', 'b', 'c', 'd') as letters
+)
+SELECT 
+    letters[0] as first_letter,    -- 索引从0开始
+    letters[3] as last_letter,
+    slice(letters, 1, 2) as middle_slice,  -- 从索引1开始，取2个元素
+    array_sort(letters) as sorted_letters
+FROM data;
+```
+
+**⚠️ 重要说明**：`slice(array, start_index, length)` 函数参数含义：
+
+* `start_index`：起始索引位置（从0开始）
+* `length`：要提取的元素个数
+* 示例：`slice(array('a','b','c','d'), 1, 2)` 返回 `['b', 'c']`
+
+#### STRUCT类型
+
+```sql
+-- 创建和访问结构体
+SELECT 
+    named_struct('name', 'Alice', 'age', 30, 'city', 'Seattle') as person,
+    named_struct(
+        'street', '123 Main St',
+        'city', 'Seattle',
+        'zipcode', '98101'
+    ) as address;
+
+-- 结构体字段访问
+WITH customer_data AS (
+    SELECT 
+        1 as id,
+        named_struct(
+            'name', 'Alice Johnson',
+            'contact', named_struct(
+                'email', 'alice@example.com',
+                'phone', '555-1234'
+            )
+        ) as profile
+)
+SELECT 
+    id,
+    profile.name as customer_name,
+    profile.contact.email as email,
+    profile.contact.phone as phone
+FROM customer_data;
+```
+
+#### JSON类型
+
+JSON作为一等公民提供原生支持，具有优异的查询性能：
+
+```sql
+-- JSON字面量和函数
+SELECT 
+    JSON '{"name": "Alice", "age": 30, "skills": ["Python", "SQL"]}' as profile,
+    json_extract_string(JSON '{"name": "Alice"}', '$.name') as name,
+    json_extract_int(JSON '{"age": 30}', '$.age') as age,
+    json_extract(JSON '{"skills": ["Python", "SQL"]}', '$.skills') as skills;
+
+-- JSON查询和过滤
+WITH user_profiles AS (
+    SELECT 
+        1 as user_id,
+        JSON '{"name": "Alice", "department": "Engineering", "skills": ["Python", "Java"]}' as profile
+    UNION ALL
+    SELECT 2, JSON '{"name": "Bob", "department": "Sales", "skills": ["Excel", "CRM"]}'
+)
+SELECT 
+    user_id,
+    json_extract_string(profile, '$.name') as name,
+    json_extract_string(profile, '$.department') as department,
+    json_extract(profile, '$.skills[0]') as primary_skill
+FROM user_profiles
+WHERE json_extract_string(profile, '$.department') = 'Engineering';
+```
+
+#### VECTOR类型
+
+专为AI/ML场景设计的向量数据类型：
+
+```sql
+-- 向量创建和计算
+SELECT 
+    VECTOR(0.1, 0.2, 0.3, 0.4) as embedding_vector,
+    l2_distance(VECTOR(0.1, 0.2, 0.3), VECTOR(0.4, 0.5, 0.6)) as l2_dist,
+    cosine_distance(VECTOR(0.1, 0.2, 0.3), VECTOR(0.4, 0.5, 0.6)) as cosine_sim,
+    dot_product(VECTOR(1.0, 2.0, 3.0), VECTOR(2.0, 3.0, 4.0)) as dot_prod;
+```
+
+### 类型转换
+
+#### 基本转换语法
+
+Lakehouse支持多种类型转换语法：
+
+```sql
+-- 三种转换方式
+SELECT 
+    CAST(123 AS STRING) as cast_syntax,
+    123::STRING as double_colon_syntax,
+    STRING(123) as function_syntax;
+```
+
+#### 安全类型转换
+
+转换失败时的处理机制：
+
+```sql
+-- TRY_CAST安全转换
+SELECT 
+    '123' as original,
+    TRY_CAST('123' AS INT) as valid_conversion,      -- 返回123
+    TRY_CAST('abc' AS INT) as invalid_conversion,    -- 返回nan
+    
+    -- 转换验证
+    CASE 
+        WHEN TRY_CAST('123' AS INT) IS NOT NULL 
+             AND CAST(TRY_CAST('123' AS INT) AS STRING) != 'nan'
+        THEN 'VALID'
+        ELSE 'INVALID'
+    END as conversion_status;
+```
+
+### 🚨 **NULL值显示特性**
+
+**重要说明**：Lakehouse中NULL值的显示具有特殊性：
+
+```sql
+-- ⚠️ 数值类型和时间类型的NULL值有特殊显示格式
+SELECT 
+    customer_id,
+    LAG(customer_id) OVER (ORDER BY registration_date) as prev_id,        -- 数值NULL显示为"nan"
+    LAG(registration_date) OVER (ORDER BY registration_date) as prev_date, -- 时间NULL显示为"NaT"
+    
+    -- 但IS NULL/IS NOT NULL逻辑判断完全正常
+    CASE 
+        WHEN LAG(customer_id) OVER (ORDER BY registration_date) IS NULL 
+        THEN 'First Customer'
+        ELSE 'Has Previous'
+    END as position_status
+FROM customers;
+```
+
+**关键要点**：
+
+* **数值类型**（INT、DOUBLE等）的NULL显示为 `"nan"`
+* **时间类型**（DATE、TIMESTAMP等）的NULL显示为 `"NaT"`
+* **字符类型**（STRING、VARCHAR等）的NULL正常显示
+* **所有类型的`IS NULL`和`IS NOT NULL`判断都正常工作**
+

+
+### 字符串函数
+
+```sql
+SELECT 
+    -- 基础字符串操作
+    upper('hello world') as uppercase,
+    lower('HELLO WORLD') as lowercase,
+    length('hello') as str_length,
+    substr('hello world', 1, 5) as substring,
+    trim('  hello  ') as trimmed,

+  AND created_time <= '2024-06-01 23:59:59';
+
+-- 查询相对时间的数据
+SELECT * FROM orders 
+WHERE created_time >= CURRENT_TIMESTAMP() - INTERVAL '1' HOUR;
+```
+
+***
+
+## 索引优化
+
+云器Lakehouse支持三种类型的索引来优化查询性能，每种索引针对不同的查询场景：
+
+### 索引类型概览
+
+| 索引类型        | 适用场景    | 支持的数据类型                          | 查询函数                                |
+| ----------- | ------- | -------------------------------- | ----------------------------------- |
+| BLOOMFILTER | 等值查询过滤  | 除interval、struct、map、array外的基本类型 | 标准WHERE条件                           |
+| INVERTED    | 全文搜索    | STRING类型                         | match\_all、match\_any、match\_phrase |
+| VECTOR      | 向量相似性搜索 | VECTOR类型                         | cosine\_distance、l2\_distance等      |
+
+### 1. 布隆过滤器索引 (BLOOMFILTER INDEX)
+
+布隆过滤器索引用于快速过滤等值查询，特别适用于高基数列。
+
+#### 创建语法
+
+```sql
+-- 基础语法
+CREATE BLOOMFILTER INDEX [IF NOT EXISTS] index_name 
+ON TABLE [schema].table_name(column_name) 
+[COMMENT 'comment'] 
+[PROPERTIES ('key'='value')];
+
+-- 示例
+CREATE BLOOMFILTER INDEX idx_customer_id 
+ON TABLE orders(customer_id) 
+COMMENT '客户ID布隆过滤器索引';
+```
+
+#### 使用示例
+
+```sql
+-- 创建测试表
+CREATE TABLE product_sales (
+    product_id INT,
+    category STRING,
+    sales_amount DOUBLE,
+    sale_date DATE
+);
+
+-- 创建布隆过滤器索引
+CREATE BLOOMFILTER INDEX idx_category_bloom 
+ON TABLE product_sales(category) 
+COMMENT '产品类别布隆过滤器索引';
+
+-- 使用索引进行等值查询（索引会自动应用）
+SELECT product_id, sales_amount
+FROM product_sales
+WHERE category = '电子产品';  -- 布隆过滤器加速此查询
+```
+
+#### 限制说明
+
+* **仅对新数据生效**：创建后只对新写入的数据有效，已有数据需要重写
+* **不支持BUILD INDEX**：布隆过滤器索引不支持对存量数据构建索引
+* **数据类型限制**：不支持interval、struct、map、array等复杂类型
+
+### 2. 倒排索引 (INVERTED INDEX)
+
+倒排索引用于全文搜索功能，支持多种文本分析器。
+
+#### 创建语法
+
+```sql
+-- 建表时创建
+CREATE TABLE documents (
+    doc_id INT,
+    title STRING,
+    content STRING,
+    INDEX content_idx (content) INVERTED COMMENT '内容倒排索引'
+);
+
+-- 已有表添加索引
+CREATE INVERTED INDEX [IF NOT EXISTS] index_name 
+ON TABLE [schema].table_name(column_name) 
+PROPERTIES('analyzer'='analyzer_type');
+```
+
+#### 分析器类型
+
+| 分析器     | 适用场景  | 说明          |
+| ------- | ----- | ----------- |
+| chinese | 中文文本  | 支持中文分词      |
+| english | 英文文本  | 英文分词和词干提取   |
+| keyword | 关键词匹配 | 不分词，完整匹配    |
+| unicode | 通用文本  | Unicode字符处理 |
+
+#### 使用示例
+
+```sql
+-- 创建倒排索引
+CREATE INVERTED INDEX IF NOT EXISTS idx_content_search 
+ON TABLE documents(content) 
+PROPERTIES('analyzer'='chinese');
+
+-- 构建索引（对已有数据生效）
+BUILD INDEX idx_content_search ON documents;
+
+-- 全文搜索查询
+-- 匹配所有关键词
+SELECT doc_id, title, content
+FROM documents
+WHERE match_all(content, '人工智能 机器学习', map('analyzer', 'chinese'));
+
+-- 匹配任意关键词
+SELECT doc_id, title, content
+FROM documents
+WHERE match_any(content, '人工智能 深度学习', map('analyzer', 'chinese'));
+
+-- 短语匹配
+SELECT doc_id, title, content
+FROM documents
+WHERE match_phrase(content, '机器学习技术', map('analyzer', 'chinese'));
+```
+
+#### 支持分区构建
+
+```sql
+-- 按分区构建索引
+BUILD INDEX idx_content_search ON documents 
+WHERE partition_date >= '2024-06-01' AND partition_date <= '2024-06-30';
+```
+
+### 3. 向量索引 (VECTOR INDEX)
+
+向量索引专为AI/ML场景设计，支持高效的向量相似性搜索。
+
+#### 创建语法
+
+```sql
+CREATE VECTOR INDEX [IF NOT EXISTS] index_name 
+ON TABLE [schema].table_name(column_name) 
+PROPERTIES(
+    "scalar.type" = "scalar_type",
+    "distance.function" = "distance_function",
+    "ef_construction" = "ef_value",
+    "M" = "M_value"
+);
+```
+
+#### 参数说明
+
+| 参数                | 可选值                                                                  | 默认值              | 说明              |
+| ----------------- | -------------------------------------------------------------------- | ---------------- | --------------- |
+| scalar.type       | f32, f16, i8, b1                                                     | f32              | 向量标量类型          |
+| distance.function | cosine\_distance, l2\_distance, jaccard\_distance, hamming\_distance | cosine\_distance | 距离计算函数          |
+| ef\_construction  | 整数                                                                   | 200              | 构建参数，影响召回率和构建时间 |
+| M                 | 整数                                                                   | 16               | 图的连接度，影响查询性能    |
+
+#### 使用示例
+
+```sql
+-- 创建包含向量列的表
+CREATE TABLE document_embeddings (
+    doc_id INT,
+    title STRING,
+    embedding VECTOR(512),  -- 512维向量
+    created_at TIMESTAMP_LTZ
+);
+
+-- 创建向量索引
+CREATE VECTOR INDEX IF NOT EXISTS idx_doc_embedding 
+ON TABLE document_embeddings(embedding) 
+PROPERTIES(
+    "scalar.type" = "f32",
+    "distance.function" = "cosine_distance",
+    "ef_construction" = "200",
+    "M" = "16"
+) COMMENT '文档向量嵌入索引';
+
+-- 构建索引
+BUILD INDEX idx_doc_embedding ON document_embeddings;
+
+-- 向量相似性搜索
+WITH query_vector AS (
+    SELECT VECTOR(0.1, 0.2, 0.3, ...) as search_embedding  -- 查询向量
+)
+SELECT 
+    d.doc_id,
+    d.title,
+    cosine_distance(d.embedding, q.search_embedding) as similarity_score
+FROM document_embeddings d
+CROSS JOIN query_vector q
+WHERE cosine_distance(d.embedding, q.search_embedding) < 0.5  -- 相似度阈值
+ORDER BY similarity_score
+LIMIT 10;
+
+-- 使用其他距离函数
+SELECT 
+    doc_id,
+    title,
+    l2_distance(embedding, VECTOR(0.1, 0.2, 0.3)) as l2_dist,
+    dot_product(embedding, VECTOR(0.1, 0.2, 0.3)) as dot_prod
+FROM document_embeddings
+ORDER BY l2_dist
+LIMIT 5;
+```
+
+### 索引管理
+
+#### 创建索引的IF NOT EXISTS支持
+
+**✅ 语法支持**：所有三种索引类型都支持 `IF NOT EXISTS` 语法：
+
+```sql
+-- 布隆过滤器索引
+CREATE BLOOMFILTER INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
+
+-- 倒排索引
+CREATE INVERTED INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
+
+-- 向量索引
+CREATE VECTOR INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
+```
+
+**⚠️ 当前实现说明**：虽然语法已支持，但在同一列创建相同类型的重复索引时仍可能报错。这表明语法解析正确，但逻辑检查还在持续完善中。
+
+#### 构建索引 (BUILD INDEX)
+
+对已有数据构建索引，仅支持INVERTED和VECTOR索引：
+
+```sql
+-- 全表构建
+BUILD INDEX index_name ON [schema].table_name;
+
+-- 分区构建
+BUILD INDEX index_name ON table_name 
+WHERE partition_col = 'value' AND other_col > 100;
+
+-- 多分区构建
+BUILD INDEX index_name ON table_name 
+WHERE partition_date >= '2024-06-01' 
+  AND partition_date <= '2024-06-30';
+```
+
+#### 查看索引信息
+
+```sql
+-- 查看表的所有索引
+DESCRIBE TABLE table_name;
+
+-- 查看特定索引详情
+DESCRIBE INDEX index_name;
+
+-- 扩展索引信息
+DESCRIBE INDEX EXTENDED index_name;
+```
+
+#### 删除索引
+
+```sql
+DROP INDEX [IF EXISTS] index_name;
+```
+
+### 查询优化建议
+
+#### 复合搜索：结合多种索引
+
+```sql
+-- 结合布隆过滤器和全文搜索
+SELECT doc_id, title, content
+FROM documents
+WHERE category = 'technology'  -- 布隆过滤器索引加速
+  AND match_any(content, '人工智能', map('analyzer', 'chinese'));  -- 倒排索引搜索
+
+-- 向量搜索与过滤结合
+SELECT doc_id, title, embedding,
+       cosine_distance(embedding, VECTOR(0.1, 0.2, 0.3)) as score
+FROM document_embeddings
+WHERE doc_type = 'article'  -- 先过滤再向量搜索
+  AND cosine_distance(embedding, VECTOR(0.1, 0.2, 0.3)) < 0.3
+ORDER BY score
+LIMIT 20;
+```
+
+***
+
+## 性能优化
+
+### 查询优化原则
+
+#### 分区裁剪优化
+
+```sql
+-- 正确的分区查询方式
+SELECT *
+FROM partitioned_table
+WHERE date_partition >= '2024-06-01'
+  AND date_partition <= '2024-06-30'
+  AND status = 'active';
+
+-- 避免的反模式
+-- WHERE year(date_partition) = 2024  -- 无法利用分区裁剪
+```
+
+#### 谓词下推优化
+
+```sql
+-- 在JOIN前过滤数据
+WITH filtered_orders AS (
+    SELECT customer_id, order_id, total_amount
+    FROM orders
+    WHERE order_date >= '2024-06-01'
+      AND total_amount > 100
+),
+active_customers AS (
+    SELECT customer_id, customer_name
+    FROM customers
+    WHERE status = 'active'
+)
+SELECT c.customer_name, o.order_id, o.total_amount
+FROM active_customers c
+JOIN filtered_orders o ON c.customer_id = o.customer_id;
+```
+
+#### 列裁剪优化
+
+```sql
+-- 只选择需要的列
+SELECT customer_id, customer_name, total_orders
+FROM customers
+WHERE registration_date >= '2024-01-01';
+
+-- 使用EXCEPT排除不需要的列
+SELECT * EXCEPT(internal_notes, created_by, updated_by)
+FROM customer_details;
+```
+
+### 分页查询优化策略
+
+根据使用的工具选择合适的分页策略：
+
+#### **📱 Web UI 分页策略**
+
+适用于：Lakehouse Studio界面探索（受10000行显示限制）
+
+```sql
+-- 策略1：条件过滤 + 小批量查看
+SELECT customer_id, order_count, last_order_date
+FROM customer_summary
+WHERE customer_type = 'premium'     -- 先过滤
+  AND last_order_date >= '2024-01-01'
+ORDER BY order_count DESC
+LIMIT 100;  -- 在显示限制内
+
+-- 策略2：时间窗口分页
+SELECT order_id, customer_id, amount
+FROM orders
+WHERE order_date >= '2024-06-01 00:00:00'
+  AND order_date < '2024-06-01 06:00:00'  -- 6小时窗口
+ORDER BY order_date
+LIMIT 1000;
+
+-- 策略3：分类查看
+SELECT product_id, product_name, price
+FROM products
+WHERE category = 'electronics'  -- 单一类别
+ORDER BY price DESC
+LIMIT 500;
+```
+
+#### **💻 编程接口分页策略**
+
+适用于：JDBC、Python SDK等客户端（无硬性行数限制）
+
+```sql
+-- 策略1：基于游标的分页（推荐）
+-- 第一页
+SELECT customer_id, order_id, order_date, amount
+FROM orders 
+WHERE customer_id >= 0  -- 起始点
+ORDER BY customer_id, order_id
+LIMIT 1000;
+
+-- 下一页（基于上一页的最后一条记录）
+SELECT customer_id, order_id, order_date, amount
+FROM orders 
+WHERE customer_id > :last_customer_id  -- 游标位置
+   OR (customer_id = :last_customer_id AND order_id > :last_order_id)
+ORDER BY customer_id, order_id
+LIMIT 1000;
+
+-- 策略2：范围分页
+-- 第一批：ID 0-9999
+SELECT * FROM large_table 
+WHERE id BETWEEN 0 AND 9999
+ORDER BY id;
+
+-- 第二批：ID 10000-19999
+SELECT * FROM large_table 
+WHERE id BETWEEN 10000 AND 19999
+ORDER BY id;
+
+-- 策略3：时间分区分页
+-- 处理2024年6月的数据，按天分批
+SELECT * FROM orders 
+WHERE order_date >= '2024-06-01'
+  AND order_date < '2024-06-02'
+ORDER BY order_id;
+```
+
+#### **🔄 流式处理策略**
+
+适用于：大数据ETL、数据导出场景
+
+```sql
+-- 策略1：分批流式处理
+-- Python伪代码示例
+"""
+batch_size = 50000
+offset = 0
+while True:
+    sql = f'''
+    SELECT * FROM large_table 
+    WHERE process_date = '2024-06-01'
+    ORDER BY id 
+    LIMIT {batch_size} OFFSET {offset}
+    '''
+    rows = execute_query(sql)
+    if not rows:
+        break
+    process_batch(rows)
+    offset += batch_size
+"""
+
+-- 策略2：条件迭代处理  
+-- 适用于有序主键的表
+"""
+last_id = 0
+batch_size = 50000
+while True:
+    sql = f'''
+    SELECT * FROM large_table 
+    WHERE id > {last_id}
+    ORDER BY id 
+    LIMIT {batch_size}
+    '''
+    rows = execute_query(sql)
+    if not rows:
+        break
+    process_batch(rows)
+    last_id = rows[-1]['id']
+"""
+```
+
+### 性能调优建议
+
+#### 1. 索引选择策略
+
+* **高基数等值查询**：使用BLOOMFILTER索引
+* **文本搜索需求**：使用INVERTED索引，选择合适的分析器
+* **向量相似性搜索**：使用VECTOR索引，调整ef\_construction和M参数
+
+#### 2. 构建策略
+
+* **大表分区构建**：分批构建索引，避免单次处理过多数据
+* **业务低峰期构建**：BUILD INDEX是同步操作，消耗计算资源
+* **监控构建进度**：通过Job Profile查看构建状态
+
+#### 3. 查询优化
+
+```sql
+-- 推荐：分区裁剪 + 索引过滤
+SELECT *
+FROM partitioned_table
+WHERE partition_date >= '2024-06-01'  -- 分区裁剪
+  AND category = 'electronics'        -- 布隆过滤器索引
+  AND match_any(description, '手机', map('analyzer', 'chinese'));  -- 倒排索引
+
+-- 避免：在索引列上使用函数
+-- 错误示例
+WHERE UPPER(category) = 'ELECTRONICS'  -- 无法利用索引
+
+-- 正确示例
+WHERE category = 'electronics'  -- 可以利用索引
+```
+
+***
+
+## 最佳实践
+
+### 查询编写建议
+
+1. **明确指定列名**：避免使用`SELECT *`，明确指定需要的列
+2. **合理使用索引**：为高频查询的过滤条件创建适当的索引
+3. **优化JOIN顺序**：将小表放在JOIN的右侧，使用MAPJOIN提示
+4. **使用分区裁剪**：在WHERE条件中直接使用分区字段
+5. **避免函数包装分区字段**：不要对分区字段使用函数
+6. **了解工具限制**：根据使用的客户端选择合适的查询策略
+
+### 数据类型选择建议
+
+1. **半结构化数据优先选择JSON**：性能优于STRING存储
+2. **时间数据根据场景选择TIMESTAMP\_LTZ或TIMESTAMP\_NTZ**
+3. **向量数据使用VECTOR类型**：获得原生性能优化
+4. **大文本数据考虑全文搜索需求**：可配合相应的搜索功能使用
+5. **理解NULL值显示特性**：数值和时间类型NULL有特殊显示格式
+
+### 索引最佳实践
+
+1. **合理选择索引类型**：根据查询模式选择合适的索引
+2. **避免过度索引**：索引会增加存储成本和写入开销
+3. **定期维护索引**：监控索引使用情况和性能影响
+4. **测试验证效果**：创建索引后验证查询性能提升
+5. **考虑数据特征**：高基数列适合布隆过滤器，文本列适合倒排索引
+
+### 错误处理建议
+
+1. **使用TRY\_CAST进行安全类型转换**
+2. **检查转换结果是否为"nan**"
+3. **为窗口函数的NULL结果提供合适的默认值处理**
+4. **在数据质量检查中识别和处理异常值**
+
+### 工具链选择建议

+
+## 常见问题
+
+### Q: 是否支持递归CTE（WITH RECURSIVE）？
+
+A: 当前版本不支持递归CTE语法。对于层次化数据处理，可以使用多级JOIN或自连接方式：
+
+```sql
+-- 替代方案：使用多级JOIN处理层次数据
+WITH level_1 AS (
+    SELECT employee_id, employee_name, 1 as level
+    FROM employees WHERE manager_id IS NULL
+),
+level_2 AS (
+    SELECT e.employee_id, e.employee_name, 2 as level
+    FROM employees e
+    JOIN level_1 l1 ON e.manager_id = l1.employee_id
+)
+SELECT * FROM level_1
+UNION ALL
+SELECT * FROM level_2;
+```
+
+### Q: 如何查询历史版本数据？
+
+A: 当前建议使用时间字段进行历史数据查询：
+
+```sql
+-- 使用创建时间字段查询历史数据
+SELECT * FROM orders 
+WHERE created_time >= '2024-06-01 00:00:00'
+  AND created_time <= '2024-06-01 23:59:59';
+
+-- 查询相对时间的数据
+SELECT * FROM orders 
+WHERE created_time >= CURRENT_TIMESTAMP() - INTERVAL '1' HOUR;
+```
+
+### Q: 为什么类型转换失败时返回"nan"而不是NULL？
+
+A: Lakehouse采用更宽松的类型转换策略，转换失败时返回特殊值"nan"。可以使用以下方式进行安全转换：
+
+```sql
+-- 检查转换是否成功
+SELECT 
+    CASE 
+        WHEN TRY_CAST(column AS INT) IS NOT NULL 
+             AND CAST(TRY_CAST(column AS INT) AS STRING) != 'nan'
+        THEN TRY_CAST(column AS INT)
+        ELSE 0  -- 或其他默认值
+    END as safe_converted_value
+FROM table_name;
+```
+
+### Q: 窗口函数中的NULL值为什么显示为特殊格式？
+
+A: 这是Lakehouse中数值类型和时间类型NULL值的特殊显示方式：
+
+```sql
+-- 数值类型NULL显示为"nan"，时间类型NULL显示为"NaT"
+SELECT 
+    LAG(customer_id) OVER (...) as prev_id,      -- 显示为"nan"
+    LAG(timestamp_column) OVER (...) as prev_time, -- 显示为"NaT"
+    CASE 
+        WHEN LAG(timestamp_column) OVER (...) IS NULL   -- IS NULL判断仍然有效
+        THEN 'No Previous Value'
+        ELSE 'Has Previous Value'
+    END as status
+FROM table_name;
+```
+
+### Q: 如何迁移Spark中的regexp\_like函数？
+
+A: Lakehouse不支持regexp\_like函数，可以使用以下替代方案：
+
+```sql
+-- 替代方案1：使用LIKE
+WHERE column_name LIKE '%pattern%'
+
+-- 替代方案2：使用regexp_extract检查是否有匹配
+WHERE regexp_extract(column_name, 'pattern', 0) != ''
+
+-- 替代方案3：组合多个条件
+WHERE column_name LIKE '%pattern1%' OR column_name LIKE '%pattern2%'
+```
+
+### Q: LATERAL VIEW explode语法不支持怎么办？
+
+A: 直接使用explode函数，无需LATERAL VIEW：
+
+```sql
+-- Spark语法
+-- SELECT id, item FROM table LATERAL VIEW explode(array_column) AS item;
+
+-- Lakehouse语法
+SELECT id, explode(array_column) as item FROM table;
+```
+
+### Q: 哪些索引支持BUILD INDEX？
+
+A: 只有INVERTED索引和VECTOR索引支持BUILD INDEX命令：
+
+```sql
+-- 支持BUILD INDEX
+BUILD INDEX inverted_idx ON table_name;   -- 倒排索引
+BUILD INDEX vector_idx ON table_name;     -- 向量索引
+
+-- 不支持BUILD INDEX
+-- BUILD INDEX bloom_idx ON table_name;   -- 布隆过滤器索引不支持
+```
+
+布隆过滤器索引只对新写入的数据生效，如需对已有数据生效，需要重写数据。
+
+### Q: Web UI显示只有10000行，但我的数据有更多，如何查看全部？
+
+A: 这是Web UI的显示限制，不是数据库的限制。建议：
+
+```sql
+-- Web UI策略：添加过滤条件
+SELECT * FROM large_table 
+WHERE category = 'electronics'  -- 先过滤
+  AND created_date >= '2024-06-01'
+LIMIT 1000;
+
+-- 或使用WEB UI的全量下载功能下载后再查看
+
+-- 或使用编程接口处理全量数据
+-- Python示例：
+"""
+import clickzetta
+conn = clickzetta.connect(...)
+cursor = conn.cursor()
+cursor.execute("SELECT * FROM large_table")
+for row in cursor.fetchall():  -- 可处理超过10000行
+    process(row)
+"""
+```
+
+### Q: 不同工具的查询限制如何确认？
+
+A: 建议在实际使用前测试：
+
+1. **Web UI**：已知限制10000行
+2. **JDBC客户端**：通过简单查询测试实际限制
+3. **Python SDK**：查阅官方文档或测试验证
+4. **BI工具**：查阅工具文档或联系厂商
+5. **自定义应用**：在开发环境中进行压力测试
+
+### Q: OFFSET功能有限制吗？
+
+A: 经过实际验证，Lakehouse的OFFSET功能没有硬性限制：
+
+```sql
+-- ✅ 这些查询都可以正常执行
+SELECT * FROM table ORDER BY id LIMIT 10 OFFSET 10000;   -- 正常
+SELECT * FROM table ORDER BY id LIMIT 10 OFFSET 15000;   -- 正常
+SELECT * FROM table ORDER BY id LIMIT 10 OFFSET 50000;   -- 正常
+
+-- 限制主要来自：
+-- 1. 使用的客户端工具的显示限制
+-- 2. 网络传输和内存的实际约束
+-- 3. 查询性能考虑（深度分页性能较差）
+```
+
+### Q: 索引的IF NOT EXISTS语法有什么特殊行为？
+
+A: 语法完全支持，但当前实现有些特殊性：
+
+```sql
+-- ✅ 语法支持
+CREATE BLOOMFILTER INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
+CREATE INVERTED INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
+CREATE VECTOR INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
+
+-- ⚠️ 当前行为：在同一列创建相同类型的重复索引时仍可能报错
+-- 这表明语法解析正确，但逻辑检查还在持续完善中
+```
+
+建议在生产环境中谨慎使用，必要时先检查索引是否已存在。

+## CTE核心语法与通用特性
+
+### 标准语法结构
+
+```sql
+WITH <cte_name1> AS (
+    SELECT column1, column2, ...
+    FROM table_name
+    WHERE condition
+),
+<cte_name2> AS (
+    SELECT column1, column2, ...
+    FROM <cte_name1>  -- 可引用前面定义的CTE
+    WHERE condition
+)
+SELECT ...
+FROM <cte_name1>
+JOIN <cte_name2> ON ...
+```
+
+### 核心优势对比
+
+| 特性 | 传统子查询 | WITH CTE | 优势体现 |
+|------|-----------|----------|----------|
+| **可读性** | 嵌套复杂 | 逻辑清晰 | 分步骤构建，易于理解 |
+| **复用性** | 重复代码 | 多次引用 | 避免重复，提高效率 |
+| **调试性** | 难以定位 | 分层测试 | 每个CTE可独立验证 |
+| **维护性** | 修改困难 | 模块化 | 局部修改，影响范围小 |
+
+---
+
+## Spark用户迁移指南
+
+### 概念映射与迁移要点
+
+Spark用户熟悉的DataFrame操作链式调用在Lakehouse中通过CTE得到完美体现：
+
+```python
+# Spark DataFrame操作思维
+df_filtered = df.filter(col("order_date") >= "2024-01-01")
+df_grouped = df_filtered.groupBy("customer_id").agg(
+    sum("amount").alias("total_amount"),
+    count("*").alias("order_count")
+)
+df_result = df_grouped.filter(col("total_amount") > 1000)
+```
+
+**云器Lakehouse CTE等价实现**：
+
+```sql
+-- CTE链式逻辑：直观对应DataFrame操作
+WITH filtered_orders AS (
+    -- 对应 df.filter()
+    SELECT customer_id, order_date, amount
+    FROM orders
+    WHERE order_date >= '1995-01-01'
+),
+grouped_summary AS (
+    -- 对应 df.groupBy().agg()
+    SELECT 
+        customer_id,
+        SUM(amount) as total_amount,
+        COUNT(*) as order_count
+    FROM filtered_orders
+    GROUP BY customer_id
+),
+final_result AS (
+    -- 对应后续的 filter()
+    SELECT customer_id, total_amount, order_count
+    FROM grouped_summary
+    WHERE total_amount > 1000
+)
+SELECT * FROM final_result
+ORDER BY total_amount DESC;
+```
+
+### DataFrame API到CTE的转换模式
+
+#### 1. 复杂聚合操作转换
+
+```python
+# Spark复杂聚合
+from pyspark.sql.functions import *
+from pyspark.sql.window import Window
+
+window_spec = Window.partitionBy("category").orderBy("date")
+result = df.withColumn("running_total", 
+                      sum("amount").over(window_spec)) \
+           .withColumn("rank", 
+                      row_number().over(window_spec.orderBy(desc("amount"))))
+```
+
+**Lakehouse CTE实现**：
+
+```sql
+-- 窗口函数与CTE结合：更直观的逻辑表达
+WITH enriched_data AS (
+    SELECT 
+        category,
+        date,
+        amount,
+        -- 对应Spark的window functions
+        SUM(amount) OVER (
+            PARTITION BY category 
+            ORDER BY date 
+            ROWS UNBOUNDED PRECEDING
+        ) as running_total,
+        ROW_NUMBER() OVER (
+            PARTITION BY category 
+            ORDER BY amount DESC
+        ) as rank
+    FROM sales_data
+),
+ranked_results AS (
+    SELECT 
+        category,
+        date,
+        amount,
+        running_total,
+        rank,
+        -- 新增分析维度
+        AVG(amount) OVER (
+            PARTITION BY category 
+            ORDER BY date 
+            ROWS 2 PRECEDING
+        ) as three_day_avg
+    FROM enriched_data
+)
+SELECT category, date, amount, running_total, rank, three_day_avg
+FROM ranked_results
+WHERE rank <= 10
+ORDER BY category, rank;
+```
+
+#### 2. JOIN操作优化转换
+
+```python
+# Spark广播JOIN
+from pyspark.sql.functions import broadcast
+
+result = large_df.join(
+    broadcast(small_df), 
+    large_df.customer_id == small_df.customer_id, 
+    "inner"
+)
+```
+
+**Lakehouse CTE优化版本**：
+
+```sql
+-- CTE + MAPJOIN：性能与可读性双重优势
+WITH large_dataset AS (
+    SELECT customer_id, order_id, amount, order_date
+    FROM fact_orders
+    WHERE order_date >= '2024-01-01'
+),
+customer_dimension AS (
+    SELECT customer_id, customer_name, customer_tier, region
+    FROM dim_customers
+    WHERE status = 'Active'
+)
+SELECT /*+ MAPJOIN(customer_dimension) */
+    ld.order_id,
+    cd.customer_name,
+    cd.customer_tier,
+    cd.region,
+    ld.amount,
+    ld.order_date
+FROM large_dataset ld
+JOIN customer_dimension cd ON ld.customer_id = cd.customer_id
+ORDER BY ld.amount DESC;
+```
+
+### Spark UDF到SQL函数的转换
+
+```python
+# Spark自定义UDF
+from pyspark.sql.types import StringType
+
+def categorize_amount(amount):
+    if amount > 1000:
+        return "High"
+    elif amount > 500:
+        return "Medium"
+    else:
+        return "Low"
+
+categorize_udf = udf(categorize_amount, StringType())
+df_result = df.withColumn("amount_category", categorize_udf(col("amount")))
+```
+
+**Lakehouse CTE实现**：
+
+```sql
+-- 内置CASE WHEN替代UDF：性能更优
+WITH categorized_orders AS (
+    SELECT 
+        order_id,
+        customer_id,
+        amount,
+        -- 内置逻辑替代UDF
+        CASE 
+            WHEN amount > 1000 THEN 'High'
+            WHEN amount > 500 THEN 'Medium'
+            ELSE 'Low'
+        END as amount_category,
+        -- 更丰富的分类逻辑
+        CASE 
+            WHEN amount > 1000 AND customer_tier = 'VIP' THEN 'Premium_High'
+            WHEN amount > 1000 THEN 'Standard_High'
+            WHEN amount > 500 THEN 'Medium'
+            ELSE 'Low'
+        END as detailed_category
+    FROM orders o
+    JOIN customers c ON o.customer_id = c.customer_id
+)
+SELECT 
+    amount_category,
+    detailed_category,
+    COUNT(*) as order_count,
+    AVG(amount) as avg_amount
+FROM categorized_orders
+GROUP BY amount_category, detailed_category
+ORDER BY avg_amount DESC;
+```
+
+---
+
+## Hive用户迁移指南
+
+### MapReduce思维到现代分析的转换
+
+Hive用户习惯的多阶段Job执行模式在Lakehouse CTE中得到简化和性能提升：
+
+#### 1. 多阶段聚合的优化
+
+```sql
+-- Hive多阶段思维（传统方式）
+-- 第一阶段：基础聚合
+INSERT OVERWRITE TABLE temp_customer_summary
+SELECT customer_id, SUM(amount) as total_amount
+FROM orders
+WHERE dt = '2024-06-01'
+GROUP BY customer_id;
+
+-- 第二阶段：二次聚合
+INSERT OVERWRITE TABLE final_customer_tiers
+SELECT 
+    CASE 
+        WHEN total_amount > 10000 THEN 'VIP'
+        ELSE 'Regular'
+    END as tier,
+    COUNT(*) as customer_count
+FROM temp_customer_summary

+## 使用SQL任务计算新客户、活跃客户和流失客户
+
+在企业运营中，通常会基于用户行为特征将用户进行分层，针对不同分层的用户针对性的做一些运营动作，针对性的做用户转化。大多数场景下，会将用户划分为新客户、活跃客户以及流失用户。
+
+* 新用户：是指在特定时间段内新注册成为用户的数量，通常用于衡量用户增长的速度和吸引力。
+* 活跃用户：是指在特定时间段内有实际使用行为的用户数量，通常用于衡量用户参与度和留存情况。
+* 流失用户：是指在特定时间段内不在访问产品的用户。企业要尽可能减少流失用户的占比，减少唤起用户的成本。
+
+本教程中，我们将基于「电商数据集」，进行留存率的分析。所使用的数据来自云器Lakehouse的共享样例数据，可以直接按照如下方式直接使用:
+```
+select * from clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore limit 10;
+```
+
+### 第一步：根据每个客户的升序订单日期创建特定于每个客户 ID 的订单序列列。
+
+```SQL
+DROP TABLE if exists eCommerce_LifeCycle_Order_Sequence;
+CREATE TABLE eCommerce_LifeCycle_Order_Sequence 
+AS
+SELECT event_date,
+       user_id,
+       ROW_NUMBER() OVER (PARTITION BY user_id ORDER BY event_date ASC) AS customer_order_sequence,
+       LAG(event_date) OVER (PARTITION BY user_id ORDER BY user_id ASC) AS previous_order_date,
+       MIN(event_date) AS first_order_date,
+       MAX(event_date) AS last_order_date
+FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore
+WHERE event_type = 'purchase'
+GROUP BY event_date,
+         user_id;
+```
+
+### 第二步：创建一个新列，为客户 ID 插入先前的订单日期，以便在以后的代码块中用于计算订单之间的时间段
+
+```SQL
+DROP TABLE if exists eCommerce_LifeCycle_Time_Between_Orders;
+CREATE TABLE eCommerce_LifeCycle_Time_Between_Orders 
+AS
+SELECT event_date,
+       user_id,
+       customer_order_sequence,
+       CASE
+         WHEN previous_order_date IS NULL THEN event_date
+         ELSE previous_order_date
+       END AS previous_order_date,
+       DATEDIFF(event_date,previous_order_date) AS days_between_orders,
+       first_order_date,
+       last_order_date
+FROM eCommerce_LifeCycle_Order_Sequence;
+```
+
+### 第三步：使用CASE 语句创建一个附加的 customer\_life\_cycle 列，以根据 days\_between\_orders 列指示订单是来自新客户、活跃客户还是已失效客户。在此示例中，如果订单发生在距上一个订单 1 到 365 天之间的任何时间，则客户被视为活跃客户；如果先前订单超过 365 天，则客户被视为已失效。
+
+```SQL
+DROP TABLE if exists eCommerce_LifeCycle;
+CREATE TABLE eCommerce_LifeCycle 
+AS
+SELECT event_date,
+       user_id,
+       CASE
+         WHEN customer_order_sequence = 1 THEN '新客户'
+         WHEN days_between_orders > 0 AND days_between_orders < 30 THEN '活跃客户'
+         WHEN days_between_orders > 30 THEN '沉睡客户'
+         ELSE '未知'
+       END AS customer_life_cycle,
+       customer_order_sequence,
+       previous_order_date,
+       CASE
+         WHEN days_between_orders IS NULL THEN 0
+         ELSE days_between_orders
+       END AS days_between_orders,
+       first_order_date,
+       last_order_date
+FROM eCommerce_LifeCycle_Time_Between_Orders;

+# STRING 类型
+
+`STRING` 类型用于表示长度大于或等于 0 的所有字符序列。该类型可以存储最大为 16MB 的文本数据。在批量、实时导入数据时，会对字段进行长度校验。如果您在导入数据时遇到超过16MB的数据，可以通过修改表的属性来调整字符串长度的限制，例如将 `STRING` 长度设置为32MB：
+
+```
+ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.string.bytes"="33554432");
+```
+
+## 语法
+
+```
+[r]'c [ ... ]'
+```
+
+- `r`：可选前缀，表示字符串中的转义字符不会被转义。这对于包含特殊字符的字符串非常有用，因为它允许字符串按原样被解释，而不是被转换成转义序列。
+- `c`：Unicode 字符集中的任意字符。
+
+## 转义序列
+
+在常规字符串文本（无 `r` 前缀）中，以下转义序列会被识别，并根据以下规则替换：
+
+- `\0` -> `\u0000`，具有代码 0 的 Unicode 字符；
+- `\b` -> `\u0008`，退格键；
+- `\n` -> `\u000a`，换行符；
+- `\r` -> `\u000d`，回车符；
+- `\t` -> `\u0009`，水平制表符；
+- `\Z` -> `\u001A`，替换；
+- `\%` -> `\%`；
+- `\_` -> `\_`；
+- `\<other char>` -> `<other char>`，跳过斜杠并保留字符原样。
+
+如果字符串具有前缀 `r`，则不会识别这些转义序列。
+
+## 示例
+
+以下是一些使用 `STRING` 类型和转义序列的示例：
+
+```
+-- 未添加 r，转义序列被解释
+SELECT 'Hello \n World!' AS col;
++---------+
+|   col   |
++---------+
+| Hello 
+ World! |
++---------+
+
+-- 添加 r，转义序列不被解释
+SELECT r'Hello \n World!' AS col;
++-----------------+
+|       col       |
++-----------------+
+| Hello \n World! |
++-----------------+
+
+-- 使用空字符串
+SELECT '' AS col;
++-----+
+| col |
++-----+
+|     |
++-----+
+
+-- 使用反斜杠
+SELECT '\\' AS col;
++-----+
+| col |
++-----+
+| \   |
++-----+
+
+-- 使用 r 前缀，反斜杠不被转义
+SELECT r'\\' AS col;
++-----+
+| col |
++-----+
+| \\  |

+# STRUCT
+
+`STRUCT` 函数用于创建一个结构体，它可以包含多个不同类型的值。结构体的组成通过一系列字段名和对应的数据类型来描述。结构体在处理复杂数据时非常有用，可以方便地将多个相关数据组织在一起。
+
+## 语法
+
+```
+STRUCT<field1_name: field1_type, field2_name: field2_type, …>

+   ```
+   SELECT named_struct('company_name', 'ClickZetta', 'employee_count', 5);
+   ```

+
+3. 在查询中使用结构体并结合其他字段：

+# 云器 Lakehouse 权限体系盘点与优化最佳实践指南
+
+## 文档信息
+- **目标读者**：系统管理员、安全管理员、数据治理团
+
+---
+
+## 一、概述
+
+在云器 Lakehouse 中，用户和角色是重要的数字资产。随着业务发展，权限体系可能变得复杂，出现权限冗余、角色闲置等问题。本指南将帮助您：
+
+- ✅ 理解云器 Lakehouse 的双层权限体系
+- ✅ 掌握通过 Studio Web 界面和 SQL 进行权限管理
+- ✅ 区分空间级和实例级两种权限盘点视角
+- ✅ 识别和清理权限冗余
+- ✅ 建立持续的权限治理机制
+
+## 二、理解云器 Lakehouse 权限体系
+
+### 2.1 双层权限架构
+
+云器 Lakehouse 采用**实例-空间**双层权限体系：
+
+```
+云器 Lakehouse Instance（实例）
+├── 实例级资源
+│   ├── Instance Users（实例用户池）
+│   │   ├── 普通用户（从全局平台同步）
+│   │   └── 服务用户（API/自动化使用）
+│   └── Instance Roles（实例级角色）
+│       ├── instance_admin（实例管理员）
+│       ├── instance_sre（实例运维）
+│       ├── instance_datasource_admin（数据源管理）
+│       └── ...其他实例级角色
+│
+└── 工作空间层
+    ├── Workspace A（工作空间A）
+    │   ├── Workspace Users（从实例用户池授权的用户）
+    │   └── Workspace Roles（空间级角色）
+    │       ├── workspace_admin
+    │       ├── workspace_dev
+    │       └── 自定义角色
+    ├── Workspace B
+    │   ├── Workspace Users
+    │   └── Workspace Roles
+    └── Workspace C
+        ├── Workspace Users
+        └── Workspace Roles
+```
+
+**关键理解**：
+- 用户首先存在于实例级用户池中
+- 通过 `CREATE USER` 命令将实例用户添加到特定工作空间
+- 实例级角色具有跨工作空间的权限
+- 工作空间级角色仅在特定工作空间内有效
+
+### 2.2 角色类型分类
+
+| 角色类型 | 作用范围 | 分配位置 | 示例 | 说明 |
+|---------|---------|---------|------|------|
+| **实例级角色** | 跨所有 Workspace | 实例层面分配 | `instance_admin`<br>`system_admin`<br>`instance_sre`<br>`instance_datasource_admin` | 拥有跨工作空间的管理权限<br>在实例级别统一管理 |
+| **空间级系统角色** | 单一 Workspace | 工作空间内分配 | `workspace_admin`<br>`workspace_dev`<br>`workspace_analyst`<br>`workspace_sre`<br>`workspace_user` | 系统预置，权限范围限于特定工作空间<br>每个工作空间独立管理 |
+| **空间级自定义角色** | 单一 Workspace | 工作空间内创建和分配 | 用户自定义角色名 | 根据业务需求创建<br>仅在创建它的工作空间内有效 |
+
+> **重要说明**：
+> - 系统预置角色中，`workspace_admin` 和 `instance_admin` 的权限不可修改
+> - 其他预置角色的权限可以根据需要进行调整
+> - 目前仅支持在工作空间内创建自定义角色，不支持创建实例级自定义角色
+
+### 2.3 用户管理流程
+
+理解用户在云器 Lakehouse 中的流转过程：
+
+```
+1. 全局平台用户（在 accounts.yunqi.com 注册）
+         ↓ 自动同步
+2. 实例用户池（存在于 Lakehouse 实例中）
+         ↓ CREATE USER 命令
+3. 工作空间用户（被授权访问特定工作空间）
+         ↓ GRANT ROLE 命令
+4. 拥有角色的用户（具有实际操作权限）
+```
+
+> **重要概念**：在工作空间中执行 `CREATE USER` 实际上是将已存在于实例用户池的用户添加到当前工作空间，这就是为什么不需要指定密码的原因。
+
+### 2.4 角色权限范围说明
+
+> **注意**：
+> - 不同角色之间的权限继承关系需要根据实际环境验证，不同版本可能有所差异
+> - `system_admin` 角色即将下线，建议使用 `instance_admin` 作为实例级管理角色
+> - 建议通过实际测试确认各角色的具体权限范围
+
+## 三、🔍 关键概念：两种盘点视角（必读）
+
+### 3.1 空间级盘点 vs 实例级盘点
+
+| 对比维度 | 📁 空间级盘点 | 🌐 实例级盘点 |
+|---------|--------------|--------------|
+| **数据来源** | information_schema（已过滤） | 全局元数据（需特殊权限） |
+| **SQL 过滤条件** | `WHERE workspace_id = current_workspace_id()` | 无过滤，可见所有数据 |
+| **可见范围** | 仅当前工作空间 | 所有工作空间 |
+| **适用场景** | 日常权限管理 | 全局安全审计 |
+| **局限性** | ❌ 无法看到其他工作空间<br>❌ 可能误判权限冗余 | ❌ 需要高级权限<br>❌ 操作复杂度高 |
+
+### 3.2 重要提示
+
+> ⚠️ **关键区别**：
+> - 使用 `information_schema` 进行的盘点都是**空间级盘点**，只能看到当前工作空间的"局部视图"
+> - 要进行实例级盘点，需要通过 Studio 管理控制台或特殊权限访问全局数据
+> - 判断方法：如果您的查询基于 `information_schema` 表，那么您正在进行空间级盘点
+
+## 五、权限盘点实践步骤
+
+### 步骤 1：明确盘点级别
+
+```sql
+-- 确认当前盘点环境和级别
+SELECT 
+    '当前盘点级别' as check_item,
+    '空间级盘点' as level,
+    current_workspace() as workspace_scope,
+    '仅可见当前工作空间数据' as visibility_limit,
+    '如需全局视图请使用管理控制台' as suggestion;
+```
+
+### 步骤 2：用户角色分布分析
+
+```sql
+-- 分析用户的角色分配情况（已脱敏）
+SELECT 
+    CASE 
+        WHEN user_name LIKE 'admin%' THEN 'admin_user_' || ROW_NUMBER() OVER (ORDER BY user_name)
+        WHEN user_name LIKE 'dev%' THEN 'dev_user_' || ROW_NUMBER() OVER (ORDER BY user_name)
+        ELSE 'user_' || ROW_NUMBER() OVER (ORDER BY user_name)
+    END as masked_user,
+    role_names,
+    LENGTH(role_names) - LENGTH(REPLACE(role_names, ',', '')) + 1 as role_count,
+    CASE 
+        WHEN role_names LIKE '%system_admin%' THEN '包含实例级角色'
+        WHEN role_names LIKE '%workspace_admin%' THEN '空间管理员'
+        WHEN role_names LIKE '%workspace_dev%' THEN '开发人员'
+        ELSE '普通用户'
+    END as user_category
+FROM information_schema.users
+ORDER BY role_count DESC;
+```
+
+### 步骤 3：角色使用情况分析
+
+```sql
+-- 分析角色的分配和使用情况
+SELECT 
+    role_name,
+    CASE 
+        WHEN role_name LIKE 'instance_%' THEN '实例级角色（在空间级视图中）'
+        WHEN role_name = 'system_admin' THEN '实例级角色（即将下线）'
+        WHEN role_name LIKE 'workspace_%' THEN '空间级-系统预置'
+        ELSE '空间级-自定义'
+    END as role_classification,
+    CASE 
+        WHEN user_names IS NULL OR user_names = '' THEN '⚠️ 未分配'
+        ELSE '✅ 已分配'
+    END as assignment_status,
+    CASE 
+        WHEN user_names IS NOT NULL THEN 
+            LENGTH(user_names) - LENGTH(REPLACE(user_names, ',', '')) + 1
+        ELSE 0
+    END as assigned_user_count,
+    comment as description
+FROM information_schema.roles
+ORDER BY 
+    CASE WHEN user_names IS NULL THEN 0 ELSE 1 END DESC,
+    role_name;
+```
+
+> **注意**：虽然 `instance_admin` 等是实例级角色，但它们也会出现在空间级的 `information_schema.roles` 视图中，这是因为这些角色在当前工作空间中有用户被授予了该角色。
+
+### 步骤 4：权限冗余检测
+
+```sql
+-- 检测潜在的权限冗余（需验证角色间是否真的存在继承关系）
+WITH permission_check AS (
+    SELECT 
+        CASE 
+            WHEN user_name LIKE 'admin%' THEN 'admin_user'
+            WHEN user_name LIKE 'dev%' THEN 'dev_user'
+            ELSE 'regular_user'
+        END as user_type,
+        role_names,
+        CASE 
+            WHEN role_names LIKE '%system_admin%' 
+                 AND role_names LIKE '%workspace_%'
+            THEN '可能存在跨级别冗余（需验证）'
+            WHEN role_names LIKE '%workspace_admin%' 
+                 AND role_names LIKE '%workspace_user%'
+            THEN '可能存在同级别冗余（需验证）'
+            ELSE '表面无冗余'
+        END as redundancy_check,
+        '建议：实际测试各角色权限以确认是否真的冗余' as action_needed
+    FROM information_schema.users
+)
+SELECT * FROM permission_check
+WHERE redundancy_check != '表面无冗余';
+```
+
+### 步骤 5：生成盘点报告
+
+```sql
+-- 生成空间级权限盘点摘要
+WITH summary AS (
+    SELECT 
+        COUNT(DISTINCT user_name) as total_users,
+        COUNT(DISTINCT role_name) as total_roles,
+        SUM(CASE WHEN user_names IS NOT NULL THEN 1 ELSE 0 END) as assigned_roles,
+        SUM(CASE WHEN user_names IS NULL THEN 1 ELSE 0 END) as unassigned_roles
+    FROM information_schema.users
+    CROSS JOIN information_schema.roles
+)
+SELECT 
+    '===== 空间级权限盘点报告 =====' as report_header,
+    current_workspace() as workspace_name,
+    total_users || ' 个用户' as user_summary,
+    total_roles || ' 个角色（' || assigned_roles || ' 已分配，' || unassigned_roles || ' 未分配）' as role_summary,
+    ROUND(assigned_roles * 100.0 / total_roles, 1) || '%' as role_utilization,
+    '注意：本报告仅包含当前工作空间数据' as important_notice
+FROM summary;
+```
+
+## 六、最佳实践建议
+
+### 6.1 分级权限管理策略
+
+#### 📁 空间级管理（日常操作）
+- **频率**：每月执行
+- **范围**：当前工作空间
+- **重点**：
+  - 清理空间内明显的角色冗余
+  - 处理长期未分配的自定义角色
+  - 优化空间内用户的角色组合
+
+#### 🌐 实例级管理（定期审计）
+- **频率**：每季度执行
+- **范围**：所有工作空间
+- **重点**：
+  - 审核 system_admin 的全局分配
+  - 检查跨空间的权限一致性
+  - 识别跨空间的账号重复
+
+### 6.2 权限分配决策树
+
+```
+用户需要跨工作空间管理？
+├─ 是 → 考虑分配 system_admin（需实例级审批）
+└─ 否 → 仅在当前工作空间分配角色
+        │
+        需要管理工作空间？
+        ├─ 是 → 分配 workspace_admin
+        └─ 否 → 需要开发权限？
+                ├─ 是 → 分配 workspace_dev
+                └─ 否 → 分配 workspace_user 或其他角色
+```
+
+### 6.3 避免常见误区
+
+| 误区 | 正确做法 |
+|------|----------|
+| 认为用户只存在于工作空间中 | 理解用户首先存在于实例用户池，然后被添加到工作空间 |
+| 仅凭空间级视图判断实例级角色冗余 | 需要实例级视图确认其全局使用情况 |
+| 假设角色间一定存在继承关系 | 实际测试验证各角色的具体权限 |
+| 一次性删除所有未使用角色 | 先了解角色用途，分批处理 |
+| 混淆实例级和空间级角色的管理位置 | 实例级角色在实例层面管理，空间级角色在工作空间内管理 |
+| 在 SQL 中使用已废弃的角色 | 使用 `instance_admin` 替代即将下线的 `system_admin` |
+
+### 6.4 管理工具选择建议
+
+| 管理任务 | 推荐工具 | 原因 |
+|---------|---------|------|
+| 日常用户授权 | Studio Web 界面 | 操作直观，不易出错 |
+| 批量权限变更 | SQL 脚本 | 效率高，可重复执行 |
+| 权限审计报表 | SQL 查询 + Studio | 结合使用效果最佳 |
+| 实例级管理 | Studio 管理控制台 | 可视化全局视图 |
+| 自动化监控 | API + SQL | 适合集成到监控系统 |
+
+### 6.5 监控指标建议
+
+1. **空间级指标**（可直接监控）
+   - 角色使用率 = 已分配角色数 / 空间内总角色数
+   - 用户平均角色数 = 总角色分配数 / 用户数
+   - 自定义角色占比 = 自定义角色数 / 总角色数
+
+2. **实例级指标**（需要全局权限）
+   - system_admin 分布 = 各空间 system_admin 用户数
+   - 跨空间用户重复率 = 重复用户数 / 总用户数
+   - 全局角色标准化程度 = 使用系统角色的空间数 / 总空间数
+
+## 七、自动化与持续改进
+
+### 7.1 创建监控视图
+
+```sql
+-- 创建空间级权限监控视图
+CREATE  VIEW workspace_permission_monitor AS
+SELECT 
+    current_date() as monitor_date,
+    current_workspace() as workspace,
+    '空间级监控' as monitor_level,
+    COUNT(DISTINCT u.user_name) as user_count,
+    COUNT(DISTINCT r.role_name) as role_count,
+    SUM(CASE WHEN r.user_names IS NOT NULL THEN 1 ELSE 0 END) as active_roles,
+    ROUND(
+        SUM(CASE WHEN r.user_names IS NOT NULL THEN 1 ELSE 0 END) * 100.0 / 
+        COUNT(DISTINCT r.role_name), 
+        1
+    ) as role_usage_percentage,
+    COUNT(DISTINCT CASE WHEN u.role_names LIKE '%system_admin%' THEN u.user_name END) as admin_users
+FROM information_schema.users u
+CROSS JOIN information_schema.roles r
+GROUP BY workspace;
+```
+
+### 7.2 定期检查脚本
+
+```sql
+-- 每月执行的权限健康检查
+WITH health_check AS (
+    -- 检查1: 未使用的角色
+    SELECT 
+        'unused_roles' as check_type,
+        COUNT(*) as issue_count,
+        '存在未分配的角色' as description
+    FROM information_schema.roles
+    WHERE user_names IS NULL OR user_names = ''
+    
+    UNION ALL
+    
+    -- 检查2: 可能的权限冗余
+    SELECT 
+        'potential_redundancy' as check_type,
+        COUNT(*) as issue_count,
+        '用户可能存在角色冗余' as description
+    FROM information_schema.users
+    WHERE LENGTH(role_names) - LENGTH(REPLACE(role_names, ',', '')) + 1 > 2
+    
+    UNION ALL
+    
+    -- 检查3: 高权限用户
+    SELECT 
+        'high_privilege_users' as check_type,
+        COUNT(*) as issue_count,
+        '拥有admin权限的用户' as description
+    FROM information_schema.users
+    WHERE role_names LIKE '%admin%'
+)
+SELECT 
+    check_type,
+    issue_count,
+    description,
+    CASE 
+        WHEN issue_count > 0 THEN '需要关注'
+        ELSE '正常'
+    END as status
+FROM health_check
+ORDER BY issue_count DESC;
+```
+
+## 八、总结与建议
+
+### 8.1 核心要点
+
+1. **明确盘点级别**：始终清楚您是在进行空间级还是实例级盘点
+2. **理解局限性**：空间级盘点无法看到全局情况，重大决策需要实例级视角
+3. **验证假设**：不要假设角色间的继承关系，需要实际验证
+4. **善用工具**：优先使用 Studio Web 界面进行日常管理，SQL 用于批量操作
+5. **持续优化**：建立定期审计机制，持续改进权限管理
+
+### 8.2 行动建议
+
+- **立即行动**：
+  - 登录 Studio 查看当前权限分布
+  - 使用本指南的查询语句进行首次空间级盘点
+- **短期计划**：
+  - 在 Studio 中设置权限变更审批流程
+  - 建立月度权限审计机制
+- **长期目标**：
+  - 实现自动化权限监控和优化
+  - 建立跨工作空间的权限标准化体系
+

+# 通过流、管道和SQL任务在 Lakehouse 上实现数仓缓慢变化维SCD
+
+## 关于SCD
+
+缓慢变化维 (Slowly Changing Dimensions, SCD) 是数据仓库设计中的一个关键概念，用于处理维度表中的数据在随时间变化时的管理。维度表包含描述性数据，例如客户信息、产品信息等，而这些信息可能会随时间发生变化。SCD提供了一种方法来处理和记录这些变化，以便数据仓库中的历史数据和当前数据都能保持一致和准确。
+
+SCD通常分为几种类型：
+
+### SCD 类型 1
+
+SCD 类型 1 通过覆盖旧数据来处理变化。这意味着当维度数据发生变化时，旧的数据将被新数据覆盖，因此不会保留历史记录。这种方法简单且快速，但会丢失历史数据。
+
+**示例**：假设客户的地址发生了变化，SCD 类型 1 将直接更新客户地址字段，旧的地址信息将被新地址覆盖。
+
+### SCD 类型 2
+
+SCD 类型 2 通过创建新行来处理变化，以保留历史记录。这种方法在维度表中添加一个新的记录，并且用新数据更新它，同时保留旧数据行，并可能使用有效日期列或版本列来跟踪不同版本的数据。
+
+**示例**：当客户的地址发生变化时，SCD 类型 2 将在维度表中插入一条新的记录，包含新地址，并可能添加一个有效日期范围来表示该地址的有效期。
+
+### SCD 类型 3
+
+SCD 类型 3 通过在表中添加额外的列来处理变化，以保留有限的历史记录。这种方法在维度表中添加一个新列来存储旧数据，当变化发生时，旧数据移到新列，新数据覆盖原来的位置。
+
+**示例**：如果客户的地址变化，SCD 类型 3 会在表中添加一个“旧地址”列，将旧地址存储到该列中，新地址存储在原始列中。

+## 概述
+
+Lakehouse 提供了标准的 Apache Iceberg Catalog REST API 接口，允许外部计算引擎（如 Apache Spark）通过统一的 REST 协议访问和查询存储在 Lakehouse 数据湖（如对象存储 OSS）中的 Iceberg 表。这使得在保持数据统一存储的同时，能够灵活选择不同的计算引擎进行数据分析。
+
+## 核心特性
+
+* **标准兼容**：兼容 Apache Iceberg REST Catalog 规范
+* **引擎支持**：支持 Spark 计算引擎
+* **权限委托**：通过 vended-credentials 模式管理存储访问权限
+* **多云支持**：支持阿里云 OSS（后续版本支持 AWS S3、腾讯云 COS 等）
+
+## 使用限制
+
+**数据类型兼容性**
+
+当通过 Spark 引擎访问 ClickZetta Lakehouse 表时，存在以下数据类型限制：
+
+暂不支持的数据类型：
+
+* **整数类型**：`SMALLINT`, `TINYINT`
+* **半结构化类型**：`JSON`
+* **向量类型**：`VECTOR`
+
+## 快速开始
+
+### 前置要求
+
+1. 云器 Lakehouse 实例的账号和密码
+
+2. 目标计算引擎环境：Spark 3.5+
+
+3. 必要的依赖包：
+
+   1. Apache Iceberg 库（Scala 2.12 / Spark 3.5.x）`：org.apache.iceberg:iceberg-spark-runtime-3.5_2.12:1.6.1`
+
+   2. 对应云对象存储的 SDK（如阿里云 OSS：`com.aliyun.oss:aliyun-sdk-oss:3.18.1`）
+
+### PySpark 集成示例
+
+#### 环境准备
+
+```Python
+import os
+import base64
+from pyspark.sql import SparkSession
+# 设置 SPARK_HOME 环境变量（根据实际安装路径调整）
+os.environ['SPARK_HOME'] = '/path/to/pyspark'
+```
+
+连接云器 Lakehouse 的认证配置
+
+```Python
+# 配置认证信息
+username = "your_username"
+password = "your_password"
+
+# 生成 Basic Authentication header
+credentials = f"{username}:{password}"
+encoded_bytes = base64.b64encode(credentials.encode("utf-8"))
+encoded_str = encoded_bytes.decode("utf-8")
+auth_header = f"Basic {encoded_str}"
+```
+
+创建 Spark Session
+
+```Python
+spark = SparkSession.builder \
+    .appName('IcebergCatalogIntegration') \
+    .config("spark.jars.packages", "org.apache.iceberg:iceberg-spark-runtime-3.5_2.12:1.6.1," + "com.aliyun.oss:aliyun-sdk-oss:3.18.1") \
+    .config('spark.sql.extensions', 'org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions') \
+    .config('spark.sql.defaultCatalog', 'clickzetta_catalog') \
+    .config('spark.sql.catalog.clickzetta_catalog', 'org.apache.iceberg.spark.SparkCatalog') \
+    .config('spark.sql.catalog.clickzetta_catalog.type', 'rest') \
+    .config("spark.sql.catalog.clickzetta_catalog.header.instanceName", "your_instance_id") \
+    .config("spark.sql.catalog.clickzetta_catalog.header.Workspace", "your_workspace") \
+    .config('spark.sql.catalog.clickzetta_catalog.uri','https://api.clickzetta.com/api/v1/catalog/iceberg-rest') \
+    .config("spark.sql.catalog.clickzetta_catalog.header.Authorization", auth_header) \
+    .config("spark.sql.catalog.clickzetta_catalog.io-impl", "org.apache.iceberg.aliyun.oss.OSSFileIO") \
+    .config("spark.sql.catalog.clickzetta_catalog.oss.endpoint", "oss-cn-hangzhou.aliyuncs.com") \
+    .config('spark.sql.catalog.clickzetta_catalog.header.X-Iceberg-Access-Delegation','vended-credentials') \
+    .config("spark.sql.catalog.clickzetta_catalog.default-namespace", "public") \
+    .config("spark.sql.catalog.clickzetta_catalog.metrics-reporter-impl", "org.apache.iceberg.metrics.LoggingMetricsReporter") \
+    .getOrCreate()
+```
+
+使用示例
+
+```Python
+# 查看所有命名空间（schemas）
+spark.sql("SHOW NAMESPACES IN clickzetta_catalog").show()
+
+# 查看指定命名空间中的表
+spark.sql("SHOW TABLES IN clickzetta_catalog.public").show()
+
+# 查看表结构
+spark.sql("DESCRIBE TABLE clickzetta_catalog.public.your_table").show()
+
+# 查询数据
+df = spark.sql("SELECT * FROM clickzetta_catalog.public.your_table LIMIT 10")df.show()
+
+# 使用 DataFrame API
+table_df = spark.table("clickzetta_catalog.public.your_table")
+table_df.filter("column_name > 100").select("col1", "col2").show()
+```

+# 通过Private Link和SSH结合来同步VPC内的RDS数据
+
+## 1. 适用场景
+
+Lakehouse Studio **数据集成** 通过 VPC 网络同步 RDS 的数据，可解决公网传输带来的如下问题：
+
+* 数据延迟高
+* 公网流量成本高
+* 不安全/不合规
+
+## 2. 历史方案优缺点总结
+
+* **纯 Private Link 方案**：不支持连接 RDS 实例，只支持 ECS 上自建的 MySQL。
+* **VPC Peering 验证走通**：但是会暴露双方内网环境，有安全风险，不建议使用。
+* **通过 IGS SDK**：通过 Private Link 支持把数据推送到 Lakehouse，但是导入调度策略需要客户自己负责，无法集成到 workflow 中。
+* **纯 SSH TUNNEL**：中间一段需要走公网，能解决 RDS 暴露公网的安全问题，但是不能解决公网流量问题。
+
+## 3. 本方案简介
+
+本方案是 Private Link 与 SSH Tunnel 两种方式相结合的方案。
+
+网络架构图（以阿里云上为例）：
+
+![](.topwrite/assets/whiteboard_exported_image.png)
+
+（客户环境也可在同 Region 的其他可用区）
+
+默认由**终端节点**侧承担开销，计费项有两个，具体可参考 [计费规则](https://help.aliyun.com/document_detail/198081.html?spm=a2c4g.120462.0.0.462f29e3tnGfMO#section-4zx-gat-sg7)。
+
+## 4. 配置方法（示例）：
+
+### Step1：环境准备
+
+**客户侧环境**：
+
+* VPC：杭州 H：专有网络 **VPC\_Customr**: [vpc-bp1qmyayneio4mlyoyeb7](https://vpc.console.aliyun.com/vpc/cn-hangzhou/vpcs/vpc-bp1qmyayneio4mlyoyeb7?type=base)，网段: `172.16.0.0/12`
+* RDS：杭州 H：私网地址：\`\` （`rm-bp15gq963ic327h8f.mysql.rds.aliyuncs.com`）
+* ECS：杭州 H：私网 IP 地址 `172.16.12.182`
+
+**Lakehouse 侧**：
+
+CZ Studio UAT 环境数据集成 EMR 集群所在 VPC 和 VWS：杭州 H
+
+| SQL vpc-bp1jvn\*\*\*\*\*\*\*\*\*\*\*u  vsw-bp1rp\*\*\*\*\*\*\*\*\*\*\*\*cii |
+| --------------------------------------------------------------------------- |
+
+CZ UAT 环境阿里云主账号：`138************83`
+
+### Step 2：在 ECS 上创建 SSH 端口转发
+
+在客户网络环境中，创建一台与 RDS 互通的 ECS，在此机器上创建端口转发：访问该 ECS 的 12345 端口，会被转发到 RDS 的 3306 端口。
+
+```Shell
+ssh -CfNg -L 12345:rm-bp15gq963ic327h8f.mysql.rds.aliyuncs.com:3306 root@127.0.0.1 -p22
+
+##验证：
+ps aux | grep ssh
+```

+
+***
+
+### Step 3：创建负载均衡 CLB
+
+* 进入负载均衡 SLB 控制台 -> 左侧 **传统型负载均衡 CLB（原 SLB）** -> **创建传统型负载均衡**
+
+* 创建监听如下：
+  ![](.topwrite/assets/c417a0f96d/c4ec47d374f0564f96375d460e06a2b096c64688.png)
+
+* 在标签页 **默认服务器组** 中添加 Step 2 中的 ECS，前端端口为 22（自定义），后端端口为转发到 RDS 的端口，本案例中为 12345。
+
+### Step 4：客户侧：创建终端节点服务
+
+* 进入 VPC 控制台，选择与 CZ 数据集成集群相同的 Region，左侧 **终端节点服务** -> **创建终端节点服务**
+* **服务资源类型 -> 传统型负载均衡 CLB**（与 Step1 一致），选择可用区 \*\*杭州 可用区H，\*\*在下拉框中选择 step1 中创建的 CLB 实例，自动接收端点连接：是，其它默认
+* 进入该终端节点服务：在 **服务白名单** 中，添加云器环境主账号：`1384322691904283`
+
+  ![](.topwrite/assets/c417a0f96d/fc469bdcdf20cda3bca8b56dfa9d4b66b010e090.png)
+
+### Step 5：Lakehouse 侧创建终端节点
+
+* 进入 VPC 控制台，选择与 CZ 数据集成集群相同的 Region，在左侧菜单中选择 **终端节点**。
+* 在终端节点页面，系统会自动发现 Step 4 中创建的终端节点服务，选择对应的 **专有网络** 后，确认创建；
+* 在客户侧和 Lakehouse 侧的**终端节点服务**和**终端节点**的**终端节点连接**信息中，可以获取域名。
+
+### **验证**：
+
+**Lakehouse Studio 数据集成**：
+
+在数据源配置中，使用如下 JDBC URL：`jdbc:mysql://ep-bp1iabb21a27719ca8a2-cn-hangzhou-h.epsrv-bp1n7rvc8qbpudxk69fr.cn-hangzhou.privatelink.aliyuncs.com:22/mysql`

+# Table（表）
+
+在云器Lakehouse中，Table（表）是存储数据的基本单位，它是数据库中组织数据的核心结构。Lakehouse 的表设计为列式存储，这种存储方式在处理分析型查询时表现出极高的效率，因为它允许查询只读取需要的列数据，而不是整行数据。这种存储结构特别适合于数据仓库和大数据分析场景，可以显著提高数据处理的速度。
+
+## 表的约束
+
+表的约束用于确保表中数据的完整性和准确性。在Lakehouse中，支持多种类型的约束，包括但不限于：
+
+### NOT NULL
+
+**NOT NULL** 约束确保列中的值不能为NULL。这是在创建表时设置的，一旦设置，该约束将不可去除，以确保列中始终有有效数据。
+
+### PRIMARY KEY
+
+**主键（PRIMARY KEY）** 用于确保表中每条记录的唯一性。在大数据场景下，由于数据量通常非常庞大，为了保证数据的唯一性而对所有 key 进行逐一检查是不现实且低效的，因此一般不推荐在大数据环境中使用主键约束。然而，Lakehouse 仍提供了对主键的支持，以便在特定场景下满足数据完整性的需求。在 Lakehouse 架构中，定义了主键的表在进行实时数据写入时，系统将自动根据主键值进行数据去重，这对于变更数据捕获（CDC）场景尤为重要。例如，您可以实时地将MySQL数据库的binlog日志同步到Lakehouse，确保数据的一致性。设置完主键后，需要通过 [实时数据接口](java_reference/realtime-upload.md) 来处理数据。在 CDC 实时写入过程中，系统将依据主键自动进行数据去重，以维护数据的准确性和完整性。
+
+#### Lakehouse 主键支持及默认行为
+
+Lakehouse 支持两种直接指定主键（primary key）的方式，且在默认情况下，其行为设置为 `ENABLE VALIDATE RELY`。这意味着，当您在创建表时指定了主键，并且没有特别指定其他行为时，系统会自动启用对主键的验证和依赖关系。
+
+在这种默认行为下，无论是实时写入操作还是通过 SQL 进行的数据写入，系统都会依据所定义的主键进行去重处理。如果尝试插入与现有主键值重复的记录，系统将拒绝执行该插入操作，以确保主键的唯一性。例如：
+
+```sql
+create table test_primary(id int primary key,name string);
+desc extended test_primary;
+insert into test_primary values(1,"1");
+insert into test_primary values(2,"1");
+-- 此时插入成功，因为主键值 1 和 2 均未重复
+insert into test_primary values(1,"1");
+-- 插入失败，因为主键值 1 已存在
+select * from test_primary;
+```
+
+从上述示例可以看出，在默认的 `ENABLE VALIDATE RELY` 模式下，系统严格维护主键的唯一性，无论是单条记录插入还是批量插入，都会进行主键冲突检查。
+
+#### 自定义主键行为
+
+如果您根据实际业务需求，希望在插入数据时仅由实时写入机制进行主键去重，而通过 SQL 写入时则不执行去重操作，可以通过将主键行为设置为 `disable NOVALIDATE RELY` 来实现。以下是具体的操作示例：
+
+```sql
+create table test_primary_di(id int primary key disable NOVALIDATE RELY ,name string);
+insert into test_primary_di values(1,"1");
+insert into test_primary_di values(2,"1");
+-- 此时插入成功，主键检查按预期执行
+insert into test_primary_di values(1,"1");
+-- 插入成功，因为在 disable NOVALIDATE RELY 模式下，SQL 写入不进行主键去重
+```
+
+需要注意的是，在 `disable NOVALIDATE RELY` 模式下，虽然实时写入仍会依据主键进行去重，但通过 SQL 进行的写入操作将不会受到主键唯一性约束的限制，这可能导致数据中出现主键重复的情况。因此，在选择此模式时，您需要对数据的写入来源和写入方式进行审慎的考虑和管理，以避免潜在的数据质量问题。

+# TIMESTAMP
+
+`TIMESTAMP` 类型用于表示日期和时间戳，可以包含时区信息。默认情况下，时间戳表示为本地时间（TIMESTAMP_LTZ）。所有操作都在当前会话的时区中执行，输出结果也以当前 Lakehouse 所在服务的时区为准。支持用户输入多种格式的时间戳，并自动转换为`TIMESTAMP`类型。输出结果为字符串格式，格式为 `'yyyy-MM-dd HH:mm:ss'`。如果用户输入包含毫秒，则输出结果也会包含毫秒。最大精度支持到微秒（µs），实际精度取决于写入时的时间戳精度。
+
+## 语法
+```
+TIMESTAMP | TIMESTAMP_LTZ
+```
+
+## 示例
+1. 使用默认时间戳格式：
+```
+SELECT TIMESTAMP '2022-12-31 00:00:00';
+SELECT TIMESTAMP_LTZ '2022-12-31 00:00:00';
+```
+2. 使用不同格式的时间戳：

++------------------------------------+
+
+| TIMESTAMP'2022-12-31 00:00:00.123' |

+
+| 2022-12-31 08:00:00.123             |
+

+
+
+```
+3. 将字符串转换为时间戳类型：
+```
+SELECT CAST('2022-12-31 00:00:00' AS TIMESTAMP);
+SELECT CAST('2022-12-31 00:00:00' AS TIMESTAMP_LTZ);
+```
+4. 使用不同的精度选项：
+```
+SELECT TIMESTAMP  '2022-12-31 00:00:00.123456'; -- 微秒精度
+SELECT TIMESTAMP  '2022-12-31 00:00:00.123'; -- 毫秒精度
+SELECT TIMESTAMP  '2022-12-31 00:00:00'; -- 秒精度
+```

+# Lakehouse Time Travel功能简介
+
+Lakehouse的Time Travel功能允许用户在定义的时间段内的任何时间点访问历史数据，包括已更改或删除的数据。Lakehouse Time Travel功能收取存储费用，并将默认保留周期为一天。请注意，如果设置的时间更长，存储费用会增加。
+
+## 应用场景
+
+1. 恢复可能被意外或有意删除的数据。
+2. 复制和备份过去关键点的数据。
+3. 分析指定时间段内的数据变化。
+## Time Travel保留期限设置
+
+Time Travel保留期限决定了您可以访问多久以前的数据。例如，如果Time Travel保留期限设置为7天，那么您可以访问过去7天内的任何时间点的数据。超过7天后，您将无法使用Time Travel访问过期的数据，且数据会被物理删除。
+Lakehouse表的历史状态默认保留周期1天（24小时），您可以通过Time Travel查询1天内的历史版本。
+
+如需保留更长周期的历史版本，您可以为每个表设置不同的数据保留周期，以满足不同的业务需求。num的设置范围为0-90。
+
+  * ```SQL
+    ALTER TABLE tablename SET PROPERTIES ('data_retention_days'='num');
+    ```
+## TIMETRAVEL查询语法
+
+```sql
+SELECT 
+    table_identifier TIMESTAMP AS OF timestamp_expression
+```
+
+通过使用TIMESTAMP AS OF子句，用户可以指定具体的时间点，查询保留期内表历史记录中指定点的精确位置或紧邻指定点之前的数据。Timestamp\_expression是一个返回时间戳类型表达式的参数，例如：
+
+* `'2023-11-07 14:49:18'`，即可强制转换为时间戳的字符串。
+* `CAST('2023-11-07 14:49:18' AS TIMESTAMP)`。
+* `CURRENT_TIMESTAMP() - INTERVAL 12 HOURS`。12小时之前的版本
+* 任何本身是时间戳类型或可强制转换为时间戳的表达式。
+
+## 查询说明
+
+* 通过指定时间点，用户可以查询到指定时间的版本数据。
+* 查询的时间点不能早于表创建时间，也不能超出数据保留周期。如果指定的时间点超出范围，将报错。
+* 如果timestamp\_expression是未来时间，也会报错，因为未来的数据是不可用的。
+
+## 权限要求
+
+* 用户需要拥有对表的SELECT权限。
+
+## 使用限制
+
+* View不支持Time Travel查询。
+* 不支持外部schema。
+* RealtimeStream实时写入未提交的数据不支持Time Travel查询，因为RealtimeStream为了提供实时查询功能，会优先写入到临时区，方便快速查询。而Time Travel查询历史版本是依靠查询提交记录，因此暂时无法查询RealtimeStream实时写入未提交的数据。
+
+## 具体案例
+
+### 分析指定时间段内的数据

+    id INT,
+    name VARCHAR(50),

+# TINYINT
+
+`TINYINT` 是一种 8 位有符号整型数据类型，用于存储范围在 -128 到 127 之间的整数值。它可以有效地节省存储空间，因为它仅使用一个字节来表示数值。
+
+## 语法
+
+```
+TINYINT
+```
+
+
+## 示例
+
+1. 创建一个包含 `TINYINT` 类型列的表：
+
+   ```sql
+   CREATE TABLE example_table (
+       id TINYINT
+   );
+   ```
+
+2. 向 `TINYINT` 类型的列插入数据：
+
+   ```sql
+   INSERT INTO example_table (id) VALUES (-100);
+   INSERT INTO example_table (id) VALUES (100);
+   ```
+
+3. 查询 `TINYINT` 类型列的数据：
+
+   ```sql
+   SELECT id FROM example_table;
+   ```
+
+4. 使用 `TINYINT` 类型列进行条件查询：
+
+   ```sql
+   SELECT id FROM example_table WHERE id > -50;
+   ```
+
+5. 创建一个包含 `TINYINT` 类型列（指定最大显示宽度）的表：
+
+   ```sql
+   CREATE TABLE example_table2 (
+       age TINYINT
+   );
+   ```
+
+6. 向 `TINYINT` 类型列（指定最大显示宽度）插入数据：
+
+   ```sql
+   INSERT INTO example_table2 (age) VALUES (25y);
+   ```
+7.  `TINYINT`  常量格式：
+
+   ```sql
+    SELECT 11y
+   ```
+## 注意事项
+
+- `TINYINT` 类型仅适用于存储较小的整数值。对于较大的数值，建议使用 `INT` 或 `BIGINT` 类型。
+- 当使用 `TINYINT` 类型存储负数时，数值范围为 -128 到 -1。若尝试插入超出此范围的负数，将导致溢出错误。
+- 当使用 `TINYINT` 类型存储正数时，数值范围为 1 到 127。若尝试插入超出此范围的正数，将导致溢出错误。

+TPC-H 是由事务处理性能委员会 (TPC) 开发的决策支持基准。它由一套面向业务的临时查询和并发数据修改组成。TPC-H 可以根据真实的生产环境建立模型，模拟销售系统的数据仓库。本次测试使用 8 张表，数据大小为 100 GB。总共测试了 22 个查询，主要性能指标是每个查询的响应时间，即从提交查询到返回结果之间的持续时间。
+TPC-H 性能测试是一个费时、费钱的过程。为了完成测试，需要准备机器、准备数据、生成报告等，往往需要数天时间以及高昂的费用。基于云器 Lakehouse 秒级弹性伸缩的虚拟集群以及共享的 TPC-H 数据集，免去了资源和数据的准备过程。基于本文提供的方法，您可以在 3 分钟内体验云器 Lakehouse 的完整性能测试并查看对比报告。
+本文代码运行在[Zeppelin](eco_integration/Zeppelin.md)。如果您想运行本文代码，请按照文档说明安装[Zeppelin](eco_integration/Zeppelin.md)。
+
+## 创建测试用AP VC
+
+```
+-- 创建分析型虚拟计算资源
+create vcluster if not exists VC_TPCH_100GB vcluster_size='Large' vcluster_type='Analytics'  AUTO_RESUME=TRUE AUTO_SUSPEND_IN_SECOND=300 min_replicas=1 max_replicas=1 comment 'TPCH 100GB TEST';
+
+use vcluster VC_TPCH_100GB;
+```
+
+## 了解待测试数据
+
+本测试使用TPC-H 100 GB dataset。基于云器Lakehouse天生的存算分离架构，共享了该数据集（clickzetta\_sample\_data.tpch\_100g），用户可以直接访问，从而免去了数据准备过程。
+
+```
+select "customer" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.customer
+union all select "lineitem" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.lineitem
+union all select "nation" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.nation
+union all select "orders" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.orders
+union all select "part" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.part
+union all select "partsupp" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.partsupp
+union all select "region" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.region
+union all select "supplier" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.supplier;
+```
+
+运行上述代码，得到测试数据集每张表的行数：

+
+## 测试过程
+
+![](.topwrite/assets/20240618195336_rec_.gif)
+
+整个过程耗时不到 3 分钟，其中 22 个 SQL 查询运行总计耗时 16.718 秒。费用方面，本次测试采用的是 Large 规格的虚拟计算集群，3 分钟的费用约为 1.38 元，相当于用一瓶水的代价完成了本次测试。

+# TRUNCATE TABLE
+
+## 功能
+
+`TRUNCATE TABLE` 命令用于快速删除表中的所有记录，但表结构及其属性将保持不变。与 `DROP TABLE` 命令不同，`TRUNCATE TABLE` 不会完全删除表，而仅删除表中的数据。
+
+## 语法
+
+```SQL
+TRUNCATE TABLE  [ IF EXISTS ] table_name;
+```
+
+**必选参数**
+
+* `table_name`：指定要清空数据的表名。
+
+**可选参数**
+
+* `IF EXISTS`：如果指定的表不存在，则不报错并继续执行其他操作。
+
+## 使用示例
+
+1. 清空名为 `employees` 的表中的所有记录：
+   ```SQL
+   TRUNCATE TABLE employees;
+   ```
+
+2. 清空表 `employees`，如果表不存在，则不报错：
+   ```SQL
+   TRUNCATE TABLE IF EXISTS employees;
+   ```
+
+# TRUNCATE TABLE PARTITION
+
+## 功能
+
+`TRUNCATE TABLE PARTITION` 命令用于清空分区表中指定分区的数据。支持通过条件筛选方式清空分区数据。如果您希望一次性清空符合某个规则条件的一个或多个分区，可以使用表达式指定筛选条件，通过筛选条件匹配分区并批量清空分区数据。
+
+## 语法
+
+* 指定分区删除：
+
+```SQL
+TRUNCATE TABLE <table_name> PARTITION (<pt_spec>)[, PARTITION (<pt_spec>)....];
+```
+
+* 指定分区筛选条件：
+
+```SQL
+TRUNCATE TABLE <table_name>  <partition_expression>;
+partition_expression::=
+   PARTITION (<partition_col> <relational_operators> <partition_col_value>)
+   | PARTITION (scalar(<partition_col>) <relational_operators> <partition_col_value>)
+   | PARTITION (<partition_filter> AND|OR <partition_filter>)
+   | PARTITION (NOT <partition_filter>)
+   | PARTITION (<partition_filter>)[,PARTITION (<partition_filter>), ...]
+```
+
+**参数说明**
+
+* `table_name`：指定表的名字。
+* `IF EXISTS`：如果表不存在，加上此参数执行该命令则不会报错。
+* `pt_spec`：必填。待清空数据的分区。当有多个分区字段格式为`(partition_col1 = partition_col_value1, partition_col2 = partition_col_value2, ...)`。partition\_col是分区字段，partition\_col\_value是分区值。分区字段不区分大小写，分区值区分大小写。支持指定多个分区值，使用逗号分隔。
+* `partition_expression`：可以包含以下几种形式：
+
+  1. **基于分区列的比较操作**：
+
+  ```SQL
+  PARTITION (<partition_col> <relational_operators> <partition_col_value>)
+  ```
+
+  * `<partition_col>`：分区表中的分区列名。
+  * `<relational_operators>`：关系运算符，如 `=`、<`、`>、<=`、`>、`<>`。
+  * `<partition_col_value>`：与分区列进行比较的值。
+  * 示例如下：
+
+  ```SQL
+  PARTITION (scalar(<partition_col>) <relational_operators> <partition_col_value>)
+  ```
+
+  * `scalar` 函数是返回单个值的函数，用于将分区列的值转换为标量值。目前lakehouse支持的分区scalar函数包含时间函数、json函数、数学函数、加密函数、正则函数、字符串函数。
+
+  * 示例如下：
+
+    ```
+    TRUNCATE TABLE sales PARTITION (lower(pt)=product1);
+    ```
+
+  2. **基于分区过滤器的复合条件**：
+
+  ```SQL
+  PARTITION (<partition_filter> AND|OR <partition_filter>)
+  ```
+
+  * `<partition_filter>`：可以是任何有效的分区过滤条件。
+  * `AND|OR`：逻辑运算符，用于组合多个过滤条件。
+  * 示例如下：
+
+    ```
+    TRUNCATE TABLE sales  PARTITION(pt1='2023' and pt2='03');
+    ```
+
+  3. **基于分区过滤器的否定条件**：
+
+  ```SQL
+  PARTITION (NOT <partition_filter>)
+  ```
+
+  * `NOT`：逻辑非运算符，用于否定一个过滤条件。
+  * 示例如下：
+
+    ```
+    TRUNCATE TABLE sales  PARTITION(pt2 not in('01','04'));
+    ```
+
+  4. **多个分区过滤器的列表**：
+
+  ```SQL
+  PARTITION (<partition_filter>)[,PARTITION (<partition_filter>), ...]
+  ```
+
+  * 允许您列出多个分区过滤条件，每个条件之间用逗号分隔。
+
+## 使用示例
+
+1. 指定分区清空
+   ```sql
+   --从表sale_detail中清空一个分区
+   TRUNCATE  TABLE sale_detail PARTITION (pt = '202402', region = 'beijing');
+   --从表sale_detail中同时清空两个分区，清空2024年1月杭州和上海地域的销售记录。
+   TRUNCATE  TABLE sale_detail PARTITION (pt = '201401', region = 'hangzhou'),
+   PARTITION (pt = '201401', region = 'shanghai');
+   ```
+
+2. 使用过滤条件清空 `sales` 表中满足分区条件 `year < 2024 AND quarter = 1` 的所有分区：
+   ```SQL
+   TRUNCATE  TABLE sales PARTITION 
+   (
+   YEAR < 2024 AND      
+   QUARTER = 1
+   );
+   ```

+# UNDROP TABLE 语句
+
+使用 UNDROP TABLE 语句可以恢复被删除的表、动态表和物化视图。是否可以恢复被删除的对象取决于数据的[保留周期](TIMETRAVEL.md)。
+
+**数据保留周期**
+
+对象能否被恢复取决于数据的保留周期。当前预览版本的数据保留周期默认为 7 天，未来将调整为 1 天。您可以通过执行 [ALTER 命令](alter.md) 来调整保留周期。请注意，修改保留周期可能会增加存储成本。
+
+**支持的对象类型**：
+
+* 表（TABLE）
+* 动态表（DYNAMIC TABLE）
+* 物化视图（MATERIALIZED VIEW）
+
+## 语法
+
+```sql
+UNDROP TABLE tablename;
+```
+
+## 参数说明
+
+* **tablename**：指定被删除的表的名称。支持恢复动态表、内部表、物化视图。
+
+## 示例
+
+### 示例 1：删除表后立即恢复
+
+```sql
+-- 创建表
+CREATE TABLE mytable(id int, name string);
+INSERT INTO mytable VALUES(1, 'aaa');
+-- 删除表
+DROP TABLE mytable;
+-- 查看表删除记录，可以看到删除时间
+SHOW TABLES HISTORY;
++---------------+------------+-------------------------+----------+------+-------+---------+----------------+-------------------------+

+# 更新表记录
+
+## 功能描述
+更新数据库表中的记录，将指定的字段值修改为新的值。
+
+## 语法格式
+```SQL
+UPDATE target_table
+       SET column_name1 = new_value1 [ , column_name2 = new_value2 , ... ]
+  [ WHERE condition ]
+[ORDER BY ...] 
+[LIMIT row_count]
+```
+
+**必选参数**
+
+- `target_table`：需要更新记录的目标表名。
+- `column_name`：需要更新的列名。
+- `new_value`：新的值，可以是常量、变量、函数调用、算术运算符、字符串操作等。支持子查询。
+
+**可选参数**
+- `condition`：更新操作的条件，用于限定哪些记录需要被更新。条件可以包含子查询和表达式。
+- `ORDER BY ...`‌按指定列排序后更新：
+  * 通常与 `LIMIT` 配合使用，控制更新顺序。
+  * 适用于分批更新或按优先级处理数据（如先处理最新记录）。
+- `LIMIT row_count`：限制更新的最大行数：
+  * 常用于分批更新大数据表，避免锁表或事务过长。
+  * 需配合 `ORDER BY` 确保更新顺序的确定性。
+
+
+## 使用示例
+
+### 示例1：更新单个字段值
+假设我们有一个名为`employees`的表，包含员工的ID、姓名和工资。现在我们要将ID为1的员工的工资增加1000元。
+
+```SQL
+UPDATE employees
+SET salary = salary + 1000
+WHERE id = 1;
+```
+
+### 示例2：同时更新多个字段值
+继续使用`employees`表，现在我们要将ID为1的员工的工资增加1000元，并将职位从"Developer"更改为"Senior Developer"。
+
+```SQL
+UPDATE employees
+SET salary = salary + 1000, position = 'Senior Developer'
+WHERE id = 1;
+```
+
+### 示例3：使用子查询更新字段值
+假设我们有一个名为`orders`的表，包含订单ID、客户ID和订单金额。我们还有一个名为`customers`的表，包含客户ID、姓名和会员等级。现在我们要将所有VIP客户的订单金额增加10%。
+
+```SQL
+UPDATE orders
+SET amount = amount * 1.1
+WHERE customer_id IN (
+  SELECT id
+  FROM customers
+  WHERE membership_level = 'VIP'
+);
+```
+### 示例4：UPDATE语句带有ORDER BY
+```
+UPDATE t SET id = id + 1 ORDER BY id DESC;
+```
+
+## 注意事项
+- 在执行更新操作时，请确保`WHERE`子句正确无误，以免错误地更新了不应该更新的记录。
+- 在对生产环境进行更新操作之前，建议先在测试环境中进行验证。

+### 功能描述
+
+`USE SCHEMA` 语句旨在改变当前会话的默认 SCHEMA 设置。当您执行此操作后，所有未明确指定 SCHEMA 的 SQL 查询和命令都将在新设定的 SCHEMA 范围内执行。这有助于简化 SQL 语句的编写，提高工作效率。
+
+### 语法
+
+```SQL
+USE [SCHEMA] schema_name;
+```
+
+### 参数说明
+
+- `schema_name`: 您希望切换至的目标 SCHEMA 名称。
+
+### 使用示例
+
+1. 切换至名为 `reporting` 的 SCHEMA：
+
+   ```SQL
+   USE reporting;
+   ```
+
+2. 在执行一系列针对 `sales` 数据表的操作时，首先切换至相应的 SCHEMA：
+
+   ```SQL
+   USE sales_schema;
+   SELECT * FROM sales_data;
+   UPDATE sales_data SET quantity = 100 WHERE product_id = 12;
+   ```
+
+3. 当需要在不同的 SCHEMA 之间频繁切换时，可以通过 `USE` 语句快速定位至特定的数据集合：
+
+   ```SQL
+   -- 从当前的 sales_schema 切换至 customer_schema
+   USE customer_schema;
+   -- 查询客户信息
+   SELECT * FROM customers;
+   -- 切换回 sales_schema
+   USE sales_schema;
+   ```
+
+4. 如果您希望在创建表时指定 SCHEMA，但不想立即切换至该 SCHEMA，可以在创建表的语句中包含 SCHEMA 名称，而无需使用 `USE` 语句：
+
+   ```SQL
+   CREATE TABLE finance_schema.ledger (
+     id INT PRIMARY KEY,
+     amount DECIMAL(10, 2) NOT NULL
+   );
+   ```
+
+## 注意事项
+- 在使用客户端工具（如[客户端SQLLine](<connect-with-cli.md>)、[DBeaver](<eco_integration/dbeaver-lakehouse.md>)等）连接时，相关操作会在整个会话期间生效。而如果您使用 Lakehouse Studio 界面，建议优先通过页面来切换 Schema 和计算集群。需要说明的是，若直接使用相关命令，其效果仅临时生效，且要和需要执行的SQL一起选中执行方可生效。

+OSS 图像存储 →  Volume 数据湖 →  AI 识别处理  →  结构化存储  →   BI 分析展示
+     ↓              ↓              ↓            ↓            ↓
+  原始图像         增量检测       AI UDF调用     数据解析入库   可视化报表
+```
+
+### 工作流实现
+
+![](.topwrite/assets/AIworkflow.png =743)
+
+#### **Task 1: 数据源刷新与增量检测**
+
+```sql
+-- 刷新 Volume，检测新增图像文件
+ALTER VOLUME sg_volume_images REFRESH;
+
+-- 记录刷新时间点，用于后续增量处理
+SET refresh_timestamp = CURRENT_TIMESTAMP();
+```
+
+**最佳实践要点**：
+
+* 定期刷新 Volume 以发现新文件
+* 使用时间戳记录刷新点，支持增量处理
+* 建议根据业务需求设置合理的刷新频率（如每 5 分钟）
+
+#### **Task 2: AI 识别与结构化处理**
+
+```sql
+-- 增量处理最近 ${last_min} 分钟内的新图像
+WITH check_new_files AS (
+    SELECT COUNT(*) AS file_count
+    FROM DIRECTORY(VOLUME sg_volume_images)
+    WHERE last_modified_time >= DATEADD(MINUTE, -${last_min}, CURRENT_TIMESTAMP())
+),
+-- AI 识别处理
+recognition AS (
+    SELECT *
+    FROM (
+        SELECT 
+            relative_path as vehicle_images,
+            pre_signed_url,
+            -- 调用 AI 外部函数进行车辆识别
+            public.fc_image_to_text('vehicle_type', pre_signed_url) as vehicle_recognition,
+            last_modified_time
+        FROM (
+            SELECT 
+                relative_path,
+                -- 生成临时访问 URL，有效期 2 小时
+                get_presigned_url(volume sg_volume_images, relative_path, 7200) as pre_signed_url,
+                last_modified_time
+            FROM DIRECTORY(VOLUME sg_volume_images)
+            WHERE last_modified_time >= DATEADD(MINUTE, -${last_min}, CURRENT_TIMESTAMP())
+        )
+    ) subq
+    WHERE EXISTS (SELECT 1 FROM check_new_files WHERE file_count > 0)
+)
+-- 解析 AI 返回的 JSON 结果并入库
+INSERT INTO vehicle_type_data (
+    car_model, car_color, year, score, 
+    vehicle_recognition, pre_signed_url, last_modified_time, process_time
+)
+SELECT 
+    get_json_object(regexp_replace(vehicle_recognition, "'", '"'), '$.result[0].name') as car_model,
+    get_json_object(regexp_replace(vehicle_recognition, "'", '"'), '$.color_result') as car_color,
+    get_json_object(regexp_replace(vehicle_recognition, "'", '"'), '$.result[0].year') as year,
+    cast(get_json_object(regexp_replace(vehicle_recognition, "'", '"'), '$.result[0].score') as decimal(16,6)) as score,
+    vehicle_recognition,
+    r.pre_signed_url,
+    last_modified_time,
+    CURRENT_TIMESTAMP() as process_time
+FROM recognition r
+WHERE EXISTS (SELECT 1 FROM check_new_files WHERE file_count > 0);
+```
+
+**最佳实践要点**：
+
+* 使用 CTE 进行增量检测，避免处理已识别的图像
+* 生成预签名 URL 供 AI 服务访问，确保安全性
+* JSON 解析时注意引号转换和数据类型转换
+* 记录处理时间，便于监控和审计
+
+#### **Task 3: 数据质量控制与异常处理**
+
+```sql
+-- 数据质量检查和异常处理
+WITH quality_check AS (
+    -- 检查识别失败的记录
+    SELECT 
+        vehicle_images,
+        pre_signed_url,
+        vehicle_recognition,
+        CASE 
+            WHEN vehicle_recognition IS NULL THEN 'AI服务调用失败'
+            WHEN score < 0.6 THEN '识别置信度过低'
+            WHEN car_model IS NULL THEN '车型识别失败'
+            ELSE '正常'
+        END as quality_status
+    FROM vehicle_type_data
+    WHERE process_time >= DATEADD(MINUTE, -${last_min}, CURRENT_TIMESTAMP())
+)
+-- 将异常记录写入错误日志表
+INSERT INTO vehicle_recognition_errors (
+    vehicle_images, pre_signed_url, error_type, 
+    error_details, retry_count, created_time
+)
+SELECT 
+    vehicle_images,
+    pre_signed_url,
+    quality_status as error_type,
+    vehicle_recognition as error_details,
+    0 as retry_count,
+    CURRENT_TIMESTAMP() as created_time
+FROM quality_check
+WHERE quality_status != '正常';
+
+-- 更新处理统计信息
+MERGE INTO vehicle_process_stats AS target
+USING (
+    SELECT 
+        DATE(CURRENT_TIMESTAMP()) as process_date,
+        COUNT(*) as total_processed,
+        SUM(CASE WHEN quality_status = '正常' THEN 1 ELSE 0 END) as success_count,
+        SUM(CASE WHEN quality_status != '正常' THEN 1 ELSE 0 END) as error_count
+    FROM quality_check
+) AS source
+ON target.process_date = source.process_date
+WHEN MATCHED THEN UPDATE SET
+    total_processed = target.total_processed + source.total_processed,
+    success_count = target.success_count + source.success_count,
+    error_count = target.error_count + source.error_count,
+    last_update_time = CURRENT_TIMESTAMP()
+WHEN NOT MATCHED THEN INSERT (
+    process_date, total_processed, success_count, 
+    error_count, last_update_time
+) VALUES (
+    source.process_date, source.total_processed, 
+    source.success_count, source.error_count, CURRENT_TIMESTAMP()
+);
+```
+
+**最佳实践要点**：
+
+* 实施数据质量检查，识别低质量结果
+* 建立错误处理机制，支持后续重试
+* 维护处理统计信息，便于监控系统健康度

+
+### 关键组件：
+
+* **AWS S3**：存储非结构化数据。
+* **非结构化数据**：从S3摄取非结构化数据，将其转换为JSON格式。
+* **非结构化Lakehouse连接器**：将数据加载到Lakehouse。
+* **Lakehouse**：存储和管理用于RAG应用的转换数据，带有向量索引和倒排索引。
+
+在本快速教程中，我们将从S3存储桶中摄取PDF/邮件/图像，使用Unstructured将其转换为标准化的JSON，然后进行分块、嵌入并加载到Lakehouse表中。之后，RAG应用可以从Lakehouse中检索数据，并以适用于RAG应用的格式获取嵌入数据和文本/图像内容。
+

+
+cz\_username：连接到Lakehouse服务的用户名
+
+cz\_password：连接到Lakehouse服务的密码
+
+cz\_service：要连接的Lakehouse服务名称
+
+cz\_instance：要连接的Lakehouse服务实例名称
+
+cz\_workspace：要连接的Lakehouse服务工作区名称
+
+cz\_schema：要连接的Lakehouse服务架构名称
+
+cz\_vcluster：要连接的Lakehouse服务虚拟集群名称

+```
+
+### 将非结构化数据放入AWS S3
+
+![](.topwrite/assets/image_1742439828203.png)
+
+### 在Lakehouse中创建索引
+
+在构建非结构化数据预处理管道之前，让我们先在Lakehouse中创建一个架构和一个表，用于存储处理后的数据。
+
+有关架构的示例，请参阅[非结构化文档](https://docs.unstructured.io/api-reference/ingest/destination-connector/singlestore#singlestore-table-schema)。如果您将使用文档中的架构，请确保嵌入式的`dims`值与您选择使用的嵌入模型的维度数量相匹配。在此示例中，它设置为768，但您的嵌入模型可能会产生不同维度的向量。
+
+```python
+# 定义用于在Lakehouse中存储数据的表名。
+raw_table_name = "raw_elements"
+silver_table_name = "elements"
+embeddings_dimensions = 768
+```
+
+```python
+# 获取连接到Lakehouse的连接参数。
+_username = os.getenv("cz_username")
+_password = os.getenv("cz_password")
+_service = os.getenv("cz_service")
+_instance = os.getenv("cz_instance")
+_workspace = os.getenv("cz_workspace")
+_schema = os.getenv("cz_schema")
+_vcluster = os.getenv("cz_vcluster")
+```
+
+Silver表旨在存储与文件和元素相关的各种元数据和内容。这两个索引优化了特定查询的性能：
+
+倒排文本索引增强了全文检索功能，使得基于文本内容查找记录更加容易。
+
+向量索引优化了向量数据的相似性搜索，这对于基于嵌入式数据比较和查找相似元素的任务非常有用。
+
+对于RAG（检索增强生成）应用开发的好处：
+
+增强搜索效率：通过支持倒排和向量搜索，此表允许RAG应用基于文本内容和语义相似性高效检索相关信息。这增强了模型查找和生成上下文相关响应的能力。
+
+提高准确性：全文和相似性搜索的结合确保了RAG应用可以访问更广泛的相关数据，从而提高了生成内容的准确性和相关性。
+
+可扩展性：借助优化的索引，该表可以处理大量数据并快速执行搜索，支持RAG应用的可扩展性需求。
+
+简化架构：将倒排文本和向量搜索功能结合到一个表中，消除了对单独的文本和向量搜索数据库的需求。这简化了维护，减少了运营开销，并提高了开发效率。
+
+数据一致性：将数据副本数量从三个减少到一个，提高了数据一致性，最小化了数据重复，并减少了数据同步和移动的需求。
+
+总体而言，这些索引确保了对文本和嵌入式字段的搜索和检索高效进行，支持快速准确的查询结果，这对于开发有效且高效的RAG应用至关重要。

+# VARCHAR(n)
+
+变长字符类型（VARCHAR）是一种可存储可变长度的字符串数据类型。该类型在存储字符串时会根据实际内容的长度进行分配空间，从而有效节省存储空间。VARCHAR 类型的字符串长度范围为 1 到 65535 个字符。
+
+## 语法
+
+```
+VARCHAR(n)
+```
+
+其中，n 表示字符串的最大长度，取值范围为 1 到 1048576。
+
+## 示例
+
+1. 创建一个 VARCHAR 类型的表：
+
+   ```
+   CREATE TABLE example_table (
+       id INT PRIMARY KEY,
+       name VARCHAR(50),
+       age INT
+   );
+   ```
+
+   在这个例子中，我们创建了一个名为 example_table 的表，其中包含三个字段：id（整数类型，主键）、name（变长字符类型，最大长度为 50 个字符）和 age（整数类型）。
+
+2. 向 VARCHAR 类型的字段插入数据：
+
+   ```
+   INSERT INTO example_table (id, name, age) VALUES (1, '张三', 25);
+   ```
+
+   在这个例子中，我们向 example_table 表中插入了一条数据，其中 name 字段的值为 '张三'，长度为 3 个字符。
+
+3. 查询 VARCHAR 类型字段的数据：
+
+   ```
+   SELECT name FROM example_table;
+   ```
+
+   在这个例子中，我们查询了 example_table 表中 name 字段的数据。

+# VIEW（视图）
+视图是一种虚拟表，它是由 SQL 查询定义的。通过创建视图，您可以像查询普通表一样查询视图。当用户查询视图时，查询结果将仅包含在定义视图的查询中指定的表和字段的数据。
+
+## 视图的优势
+
+1. 简化复杂的 SQL 查询：通过将复杂的查询定义为视图，您可以在需要时直接查询视图，而无需每次都重写复杂的查询。
+2. 保护数据：视图可以限制用户访问基础表中的数据，只允许他们访问视图中定义的数据。
+3. 更好的数据组织：视图可以帮助您更好地组织和管理数据，使其更易于理解和使用。
+
+## 视图的限制
+
+1. 视图是只读的，无法对视图执行 DML（插入、更新、删除）操作。
+2. 视图的性能可能会受到基础表数据量和查询复杂度的影响。
+
+## 视图管理
+
+- [创建视图](CREATEVIEW.md)：通过指定 SQL 查询来创建视图。
+- [删除视图](DROPVIEW.md)：删除已存在的视图。
+- [查看视图详情](DESCVIEW.md)：查看视图的结构和定义。
+
+## 使用案例
+
+1. 计算利润和税后收入：
+
+   ```
+   CREATE VIEW v_sales AS
+   SELECT revenue - cost AS profit, (revenue - cost) * tax_rate AS tax_amount, (revenue - cost) * (1 - tax_rate) AS net_income
+   FROM table1;
+   ```
+
+2. 筛选特定部门的员工信息：
+
+   ```
+   CREATE VIEW v_sales_department AS
+   SELECT id, name, position, salary
+   FROM employees
+   WHERE department = 'Sales';
+   ```
+
+3. 汇总每个月的销售数据：
+
+   ```
+   CREATE VIEW v_monthly_sales AS
+   SELECT DATE_TRUNC('month', sale_date) AS month, SUM(revenue) AS total_sales
+   FROM sales_data
+   GROUP BY month;

+# LIST 命令
+
+## 简介
+
+LIST 命令返回已经存储在 Lakehouse 内部或者外部 Volume 中的文件列表。该命令可以在 Studio 和 Lakehouse 客户端中运行。
+
+## 使用场景
+
+* **导入前文件验证**：在将数据文件导入表前，确认文件已成功上传到 Volume 中，并检查文件命名是否符合规范。
+* **导出后确认**：使用 COPY INTO 将数据导出到 Volume 后，验证所有文件是否正确生成，以及文件大小是否合理。
+* **文件清理前确认**：在执行 REMOVE 命令删除 Volume 中的文件前，可使用 LIST 命令确认文件列表，避免误操作。
+
+## 语法
+
+```
+LIST { VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME } 
+     [ SUBDIRECTORY 'subdir'| REGEXP = 'pattern' ]
+```
+
+## 参数说明
+
+* `VOLUME volume_name `：列出指定外部 VOLUME 中的所有文件。
+* `TABLE VOLUME table_name `：列出指定表的 VOLUME 空间下的所有文件。
+* `USER VOLUME `：列出当前用户的 Volume 空间下的所有文件。
+* `SUBDIRECTORY 'subdir': `：可选参数。用于指定要列出内容的 Volume 子目录，此选项可帮助缩小结果范围。
+* `REGEXP = 'pattern': `：可选参数。用于指定过滤返回文件的正则表达式模式，您可以精确筛选出符合特定命名规则或格式的文件。
+
+## 示例
+
+* 列出外部 VOLUME `foodimages` 中所有含有数字“1”的文件：
+
+```
+LIST VOLUME foodimages REGEXP = '.*1.*'
+```
+
+* 列出外部 VOLUME `parquet_files` 中，`t_search_log` 子目录中的所有文件：
+
+```
+LIST VOLUME parquet_files SUBDIRECTORY 't_search_log'
+```
+
+* 列出外部 VOLUME `parquet_file` 中，`t_search_log` 子目录中以 `c000` 结尾的文件：
+
+```
+LIST VOLUME parquet_file SUBDIRECTORY 't_search_log' REGEXP = '.*c000' ;
+```
+
+## 注意事项
+
+* 用户必须具有相应 Volume 的 `READ ` 权限才能执行 `LIST ` 命令。

+# 窗口函数（Window Function）
+
+## 概述
+
+窗口函数（Window Function）是云器Lakehouse SQL中一种强大的分析功能，它允许在一组相关行上执行计算，而不仅仅是针对单个行。通过使用WINDOW子句，可以定义一个或多个命名的窗口，然后在窗口函数中引用这些窗口，避免重复编写相同的窗口规范，使查询更加简洁和易维护。
+
+## 语法
+
+```sql
+WINDOW <window_name> AS (<window_specification>, ...)
+```
+
+### 参数说明
+
+* **window\_name**: 窗口的名称，必须是有效的标识符，不能与表名或列名冲突
+* **window\_specification**: 窗口规范，定义窗口的范围和顺序，包含以下部分：
+  * `PARTITION BY`: 指定数据分组方式，每个组是一个分区
+  * `ORDER BY`: 指定每个分区内的数据排序方式
+  * `frame_clause`: 指定窗口框架，限制窗口函数的计算范围
+
+### 窗口框架类型
+
+1. **ROWS Frame**: 基于行数的窗口框架
+2. **RANGE Frame**: 基于值范围的窗口框架
+
+## 环境准备
+
+### 创建测试表
+
+```sql
+CREATE TABLE IF NOT EXISTS sales(
+    month INT,
+    sales INT,
+    profit DOUBLE
+);
+```
+
+### 插入测试数据
+
+```sql
+INSERT INTO sales (month, sales, profit) VALUES
+(1, 100, 0.1),
+(2, 120, 0.15),
+(3, 80, 0.05),
+(4, 150, 0.2),
+(5, 90, 0.1),
+(6, 110, 0.12);
+```
+
+## 使用示例
+
+### 示例1：移动窗口聚合 - 计算移动和与移动平均
+
+**业务场景**: 计算当前月及前两个月的销售总和与平均值
+
+```sql
+SELECT month, sales, 
+       SUM(sales) OVER w AS sum_sales, 
+       AVG(sales) OVER w AS avg_sales
+FROM sales
+WINDOW w AS (ORDER BY month ROWS BETWEEN 2 PRECEDING AND CURRENT ROW);
+```
+
+**执行结果**:
+
+```
++-------+-------+-----------+--------------------+
+| month | sales | sum_sales | avg_sales          |
++-------+-------+-----------+--------------------+
+| 1     | 100   | 100       | 100.0              |
+| 2     | 120   | 220       | 110.0              |
+| 3     | 80    | 300       | 100.0              |
+| 4     | 150   | 350       | 116.67             |
+| 5     | 90    | 320       | 106.67             |
+| 6     | 110   | 350       | 116.67             |
++-------+-------+-----------+--------------------+
+```
+
+**说明**: 窗口w定义了一个滑动窗口，包含当前行和前2行，因此每行都会计算最近3个月的销售总和与平均值。
+
+***
+
+### 示例2：多窗口排名 - 季度排名与年度排名
+
+**业务场景**: 同时计算销售额在季度内和全年的排名
+
+```sql
+SELECT month, sales, 
+       RANK() OVER w1 AS rank_quarter, 
+       ROW_NUMBER() OVER w2 AS rank_year
+FROM sales
+WINDOW w1 AS (PARTITION BY CEIL(month / 3) ORDER BY sales DESC),
+       w2 AS (ORDER BY sales DESC);
+```
+
+**执行结果**:
+
+```
++-------+-------+--------------+-----------+
+| month | sales | rank_quarter | rank_year |
++-------+-------+--------------+-----------+
+| 4     | 150   | 1            | 1         |
+| 2     | 120   | 1            | 2         |
+| 6     | 110   | 2            | 3         |
+| 1     | 100   | 2            | 4         |
+| 5     | 90    | 3            | 5         |
+| 3     | 80    | 3            | 6         |
++-------+-------+--------------+-----------+
+```
+
+**说明**:
+
+* w1窗口按季度（每3个月）分区，计算各季度内的销售排名
+* w2窗口不分区，计算全年的销售排名
+* 使用CEIL(month/3)将月份分为Q1(1-3月)、Q2(4-6月)等
+
+***
+
+### 示例3：累积聚合 - 从年初至今的统计
+
+**业务场景**: 计算从年初到当前月的累积销售额、平均利润率等
+
+```sql
+SELECT month, sales, profit,
+       SUM(sales) OVER w AS cumulative_sales,
+       AVG(profit) OVER w AS avg_profit,
+       MAX(sales) OVER w AS max_sales,
+       MIN(sales) OVER w AS min_sales
+FROM sales
+WINDOW w AS (ORDER BY month ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW);
+```
+
+**执行结果**:
+
+```
++-------+-------+--------+------------------+------------+-----------+-----------+
+| month | sales | profit | cumulative_sales | avg_profit | max_sales | min_sales |
++-------+-------+--------+------------------+------------+-----------+-----------+
+| 1     | 100   | 0.1    | 100              | 0.1        | 100       | 100       |
+| 2     | 120   | 0.15   | 220              | 0.125      | 120       | 100       |
+| 3     | 80    | 0.05   | 300              | 0.1        | 120       | 80        |
+| 4     | 150   | 0.2    | 450              | 0.125      | 150       | 80        |
+| 5     | 90    | 0.1    | 540              | 0.12       | 150       | 80        |
+| 6     | 110   | 0.12   | 650              | 0.12       | 150       | 80        |
++-------+-------+--------+------------------+------------+-----------+-----------+
+```
+
+**说明**: `UNBOUNDED PRECEDING`表示从分区的第一行开始，`CURRENT ROW`表示到当前行结束，实现累积计算。
+
+***
+
+### 示例4：时间序列分析 - 环比数据对比
+
+**业务场景**: 查看每月销售额与上月、下月的对比及环比变化
+
+```sql
+SELECT month, sales,
+       LAG(sales, 1) OVER w AS prev_sales,
+       LEAD(sales, 1) OVER w AS next_sales,
+       sales - LAG(sales, 1) OVER w AS sales_change
+FROM sales
+WINDOW w AS (ORDER BY month);
+```
+
+**执行结果**:
+
+```
++-------+-------+------------+------------+--------------+
+| month | sales | prev_sales | next_sales | sales_change |
++-------+-------+------------+------------+--------------+
+| 1     | 100   | NULL       | 120        | NULL         |

++-------+-------+------------+------------+--------------+
+```
+
+**说明**:
+
+* `LAG(sales, 1)`: 获取上一行的销售额
+* `LEAD(sales, 1)`: 获取下一行的销售额
+* 第一行和最后一行的prev\_sales和next\_sales为NULL
+
+***
+
+### 示例5：多种排名函数对比
+
+**业务场景**: 理解不同排名函数的差异
+
+```sql
+SELECT month, sales,
+       DENSE_RANK() OVER w AS dense_rank,

+| 5     | 90    | 0.1    | 100         | 110        | 120          |
+| 6     | 110   | 0.12   | 100         | 110        | 120          |
++-------+-------+--------+-------------+------------+--------------+
+```
+
+**说明**:
+
+* `FIRST_VALUE()`: 返回窗口中第一行的值
+* `LAST_VALUE()`: 返回窗口中最后一行的值（需要UNBOUNDED FOLLOWING才能看到真正的最后一行）
+* `NTH_VALUE(expr, n)`: 返回窗口中第n行的值
+
+***
+
+### 示例7：RANGE窗口框架 - 基于值范围的窗口
+
+**业务场景**: 找出销售额在±10范围内的所有记录并统计
+
+```sql
+SELECT month, sales,
+       SUM(sales) OVER w AS range_sum,
+       COUNT(*) OVER w AS range_count
+FROM sales
+WINDOW w AS (ORDER BY sales RANGE BETWEEN 10 PRECEDING AND 10 FOLLOWING);
+```
+
+**执行结果**:
+
+```
++-------+-------+-----------+-------------+
+| month | sales | range_sum | range_count |
++-------+-------+-----------+-------------+
+| 3     | 80    | 170       | 2           |
+| 5     | 90    | 270       | 3           |
+| 1     | 100   | 300       | 3           |
+| 6     | 110   | 330       | 3           |
+| 2     | 120   | 230       | 2           |
+| 4     | 150   | 150       | 1           |
++-------+-------+-----------+-------------+
+```
+
+**说明**:
+
+* RANGE窗口基于值的范围而非行数
+* 对于sales=100的行，窗口包含销售额在\[90, 110]范围内的所有行
+* 对于sales=150的行，只有它自己在\[140, 160]范围内
+
+***
+
+### 示例8：综合分析 - 多维度业务报表（高级）
+
+**业务场景**: 生成包含排名、累积、环比和占比的综合分析报表
+
+```sql
+SELECT 
+    month,
+    sales,
+    -- 排名相关
+    ROW_NUMBER() OVER w1 AS row_num,
+    RANK() OVER w1 AS sales_rank,
+    -- 累积统计
+    SUM(sales) OVER w2 AS ytd_sales,
+    AVG(sales) OVER w2 AS ytd_avg,
+    -- 环比对比
+    LAG(sales) OVER w1 AS prev_month_sales,
+    sales - LAG(sales) OVER w1 AS mom_change,
+    -- 占比分析
+    ROUND(sales * 100.0 / SUM(sales) OVER w3, 2) AS pct_of_total
+FROM sales
+WINDOW 
+    w1 AS (ORDER BY month),
+    w2 AS (ORDER BY month ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW),
+    w3 AS (ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING);
+```
+
+**执行结果**:
+
+```
++-------+-------+---------+------------+-----------+---------+------------------+------------+---------------+
+| month | sales | row_num | sales_rank | ytd_sales | ytd_avg | prev_month_sales | mom_change | pct_of_total  |
++-------+-------+---------+------------+-----------+---------+------------------+------------+---------------+
+| 1     | 100   | 1       | 1          | 100       | 100.0   | NULL             | NULL       | 15.38         |
+| 2     | 120   | 2       | 2          | 220       | 110.0   | 100              | 20         | 18.46         |
+| 3     | 80    | 3       | 3          | 300       | 100.0   | 120              | -40        | 12.31         |
+| 4     | 150   | 4       | 4          | 450       | 112.5   | 80               | 70         | 23.08         |
+| 5     | 90    | 5       | 5          | 540       | 108.0   | 150              | -60        | 13.85         |
+| 6     | 110   | 6       | 6          | 650       | 108.33  | 90               | 20         | 16.92         |
++-------+-------+---------+------------+-----------+---------+------------------+------------+---------------+
+```
+
+**说明**:
+
+* 此示例同时使用了3个不同的窗口定义
+* w1: 按月份排序，用于排名和环比
+* w2: 累积窗口，用于YTD（Year-To-Date）计算
+* w3: 完整窗口，用于计算总和并计算占比
+* 展示了如何在一个查询中实现复杂的多维度分析
+
+***
+
+### 示例9：数据分桶 - NTILE函数应用
+
+**业务场景**: 将销售数据按业绩分为高中低三档
+
+```sql
+SELECT 
+    month,
+    sales,
+    NTILE(3) OVER w AS sales_tier,
+    CASE 
+        WHEN NTILE(3) OVER w = 1 THEN 'High'
+        WHEN NTILE(3) OVER w = 2 THEN 'Medium'  
+        ELSE 'Low'
+    END AS tier_label
+FROM sales
+WINDOW w AS (ORDER BY sales DESC);
+```
+
+**执行结果**:
+
+```
++-------+-------+------------+------------+
+| month | sales | sales_tier | tier_label |
++-------+-------+------------+------------+
+| 4     | 150   | 1          | High       |
+| 2     | 120   | 1          | High       |
+| 6     | 110   | 2          | Medium     |
+| 1     | 100   | 2          | Medium     |
+| 5     | 90    | 3          | Low        |
+| 3     | 80    | 3          | Low        |
++-------+-------+------------+------------+
+```
+
+**说明**: `NTILE(n)`将排序后的数据尽可能平均地分成n个桶，常用于分层分析、ABC分类等场景。
+
+***
+
+### 示例10：累积分布 - CUME\_DIST函数应用
+
+**业务场景**: 计算每个销售额在整体中的累积分布百分位
+
+```sql
+SELECT 
+    month,
+    sales,
+    CUME_DIST() OVER w AS cumulative_dist,
+    ROUND(CUME_DIST() OVER w * 100, 2) AS percentile
+FROM sales
+WINDOW w AS (ORDER BY sales);
+```
+
+**执行结果**:
+
+```
++-------+-------+------------------+------------+
+| month | sales | cumulative_dist  | percentile |
++-------+-------+------------------+------------+
+| 3     | 80    | 0.167            | 16.67      |
+| 5     | 90    | 0.333            | 33.33      |
+| 1     | 100   | 0.500            | 50.00      |
+| 6     | 110   | 0.667            | 66.67      |
+| 2     | 120   | 0.833            | 83.33      |
+| 4     | 150   | 1.000            | 100.00     |
++-------+-------+------------------+------------+
+```
+
+**说明**: `CUME_DIST()`返回小于或等于当前值的行数占总行数的比例，表示当前值在数据集中的累积分布位置。
+
+***
+
+## 窗口框架详解
+
+### ROWS vs RANGE
+
+| 框架类型  | 说明       | 示例                                            |
+| ----- | -------- | --------------------------------------------- |
+| ROWS  | 基于物理行数   | `ROWS BETWEEN 2 PRECEDING AND CURRENT ROW`    |
+| RANGE | 基于值的逻辑范围 | `RANGE BETWEEN 10 PRECEDING AND 10 FOLLOWING` |
+
+### 边界关键字
+
+* `UNBOUNDED PRECEDING`: 分区的第一行
+* `UNBOUNDED FOLLOWING`: 分区的最后一行
+* `CURRENT ROW`: 当前行
+* `n PRECEDING`: 当前行之前的第n行（ROWS）或值-n的行（RANGE）
+* `n FOLLOWING`: 当前行之后的第n行（ROWS）或值+n的行（RANGE）
+
+***
+
+## 常用窗口函数分类
+
+### 聚合函数
+
+* `SUM()`, `AVG()`, `COUNT()`, `MAX()`, `MIN()`
+
+### 排名函数
+
+* `ROW_NUMBER()`: 连续唯一行号
+* `RANK()`: 相同值同排名，有间隔
+* `DENSE_RANK()`: 相同值同排名，无间隔
+* `PERCENT_RANK()`: 百分比排名
+* `NTILE(n)`: 将数据分成n个桶
+* `CUME_DIST()`: 累积分布值
+
+### 取值函数
+
+* `LAG()`: 访问前面的行
+* `LEAD()`: 访问后面的行
+* `FIRST_VALUE()`: 窗口第一个值
+* `LAST_VALUE()`: 窗口最后一个值
+* `NTH_VALUE()`: 窗口第n个值
+
+***
+
+## 最佳实践
+
+### 1. 使用WINDOW子句提高可读性
+
+❌ **不推荐**（重复定义窗口）:
+
+```sql
+SELECT month,
+       SUM(sales) OVER (ORDER BY month ROWS BETWEEN 2 PRECEDING AND CURRENT ROW),
+       AVG(sales) OVER (ORDER BY month ROWS BETWEEN 2 PRECEDING AND CURRENT ROW)
+FROM sales;
+```
+
+✅ **推荐**（使用WINDOW子句）:
+
+```sql
+SELECT month,
+       SUM(sales) OVER w,
+       AVG(sales) OVER w
+FROM sales
+WINDOW w AS (ORDER BY month ROWS BETWEEN 2 PRECEDING AND CURRENT ROW);
+```
+
+### 2. 合理使用PARTITION BY
+
+对于分组分析，使用PARTITION BY可以在不破坏数据结构的情况下进行组内计算：
+
+```sql
+-- 示例：按类别分别计算排名
+SELECT category, month, sales,
+       RANK() OVER w AS rank_in_category
+FROM sales_by_category
+WINDOW w AS (PARTITION BY category ORDER BY sales DESC);
+```
+
+**执行结果**:
+
+```
++-------------+-------+-------+------------------+
+| category    | month | sales | rank_in_category |
++-------------+-------+-------+------------------+
+| Clothing    | 2     | 600   | 1                |
+| Clothing    | 3     | 550   | 2                |
+| Clothing    | 1     | 500   | 3                |
+| Electronics | 2     | 1200  | 1                |
+| Electronics | 1     | 1000  | 2                |
+| Electronics | 3     | 900   | 3                |
++-------------+-------+-------+------------------+
+```
+
+说明：每个类别内独立计算排名，互不影响。
+
+### 3. 注意LAST\_VALUE的窗口范围
+
+如果要获取真正的最后一个值，必须使用`UNBOUNDED FOLLOWING`：
+
+```sql
+WINDOW w AS (ORDER BY month ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING)
+```
+
+### 4. 特定注意事项
+
+在Lakehouse中，建议在查询末尾添加LIMIT子句以提高性能：
+
+```sql
+SELECT ... FROM ... WINDOW ... LIMIT 50;
+```
+
+***
+
+## 性能优化建议
+
+1. **索引优化**: 在ORDER BY和PARTITION BY使用的列上创建适当的索引
+2. **窗口范围**: 尽量使用较小的窗口范围以减少计算量
+3. **复用窗口定义**: 使用WINDOW子句避免重复定义相同窗口
+4. **分区策略**: 合理使用PARTITION BY减少每个窗口的数据量
+
+***
+
+## 常见问题
+
+### Q1: WINDOW子句必须放在哪里？
+
+A: WINDOW子句必须放在FROM和WHERE子句之后，ORDER BY子句之前。
+
+### Q2: 能否在同一个查询中定义多个窗口？
+
+A: 可以，使用逗号分隔多个窗口定义。
+
+### Q3: ROWS和RANGE的主要区别是什么？
+
+A: ROWS基于物理行数，RANGE基于值的逻辑范围。当有重复值时，RANGE会包含所有具有相同值的行。
+
+### Q4: 为什么LAST\_VALUE没有返回预期的最后一个值？
+
+A: 需要显式指定`ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING`来包含整个分区。

+## 功能介绍
+公用表表达式（CTE，Common Table Expression）是一种在单个 SQL 查询中定义的临时结果集，其作用范围仅限于定义它的查询语句。CTE 的主要优点在于可以提高 SQL 语句的可读性和重用性。
+
+## 语法结构
+```
+WITH
+    <cte_name1> AS (SELECT ...),
+    [<cte_name2> AS (SELECT ...)],
+    [<cte_nameN> AS (SELECT ...)]
+SELECT ...
+```
+
+**参数说明：**
+
+- `<cte_name>`：指定公用表表达式的名称，用于在查询中引用。
+
+## 使用示例
+
+**示例1：简单的CTE查询**
+
+假设我们有一个名为 `orders` 的表，包含 `album_name` 和 `album_year` 两个字段。我们想要查询1976年发行的所有专辑名称，并按名称排序。使用CTE可以简化查询语句，如下所示：
+
+```sql
+WITH
+my_cte AS (SELECT * FROM orders WHERE album_year = 1976),
+my_cte2 AS (SELECT album_name,count(*) FROM my_cte group by album_name)
+SELECT album_name FROM my_cte2 ORDER BY album_name;
+```
+
+**示例2：带过滤条件的CTE查询**
+
+如果我们想查询1976年发行的专辑名称，但仅限于某个特定歌手的作品，可以在CTE中添加过滤条件：
+
+```sql
+WITH my_cte AS (SELECT * FROM orders WHERE album_year = 1976 AND artist = 'ArtistName')
+SELECT album_name FROM my_cte ORDER BY album_name;
+```

+# Lakehouse Zettapark
+
+Zettapark 是一个用于处理云器 Lakehouse 数据的 Python 库。它提供了一个高级的 Python API，用于在云器 Lakehouse 中执行 SQL 查询、操作数据和处理结果。Zettapark 使得在 Python 中使用云器 Lakehouse 变得更加简单和高效。你可以使用 Zettapark 执行 SQL 查询、操作数据和处理结果，就像在 Python 中使用 pandas 一样。
+
+你也可以[下载对应的Jupyter Notebook文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/Zettapark/Zettapark_quickstart.ipynb)，方便直接运行本 Demo。
+
+在 Zettapark 中执行 pandas 操作，会被翻译成 SQL 在云器 Lakehouse 中执行，从而实现分布式计算。
+
+比如以下 Python 代码：
+
+< 10)
+```
+
+在云器 Lakehouse 里执行的 SQL 是：
+
+```
+SELECT a, b FROM ( SELECT col1 AS a, col2 AS b FROM  VALUES (CAST(1 AS INT), CAST(3 AS INT)), (CAST(2 AS INT), CAST(10 AS INT))) WHERE ((a + b) < CAST(10 AS INT)) LIMIT 10;
+```
+
+## 安装clickzetta\_zettapark\_python
+
+```
+!pip install -q --upgrade clickzetta_zettapark_python -i https://pypi.tuna.tsinghua.edu.cn/simple
+```
+
+## 创建会话
+
+使用Zettapark的第一步是与ClickZetta Lakehouse建立会话。
+
+导入Session类。
+
+```python
+from clickzetta.zettapark.session import Session
+```
+
+和ClickZetta Connector for Python一样，Zettapark的函数中使用的相同参数（例如service、instance、用户名等）与云器Lakehouse建立会话建立会话。
+dict构造一个包含这些参数的名称和值的字典 (username、password、service、instance、workspace、schema等）。
+
+要创建会话包括如下：
+
+```
+创建一个 Python 字典 ( dict)，其中包含用于连接到 ClickZetta Lakehouse 的参数的名称和值。
+
+将此字典传递给Session.builder.configs方法以返回具有这些连接参数的构建器对象。
+
+create调用的方法建立builder会话。
+```
+
+以下示例使用dict包含连接参数来创建新会话：
+
+```
+hints = dict()
+hints['sdk.job.timeout'] = 3
+hints['query_tag'] = 'test_conn_hints_zettapark'
+connection_parameters = {
+  "username": "",
+  "password": "",
+  "service": "<region\_id>
+
+验证会话是否创建成功：
+
+```python
+df = session.sql("show schemas;")
+df.show(5)
+```
+
+```
+---------------------------
+|`schema_name`            |
+---------------------------
+|automobile               |
+|automv_schema            |
+|brazilianecommerce       |
+|continues_computing      |
+|continues_pipeline_demo  |
+---------------------------
+```
+
+## 在 Zettapark Python 中使用 DataFrame
+
+在 Zettapark 中，查询和处理数据的主要方式是通过 DataFrame。本主题介绍如何使用 DataFrame。
+
+要检索和操作云器 Lakehouse Table 里的数据，请使用 DataFrame 类。DataFrame 表示延迟评估的关系数据集：它仅在触发特定操作时执行计算。
+
+要将数据检索到 DataFrame 中：
+
+```
+1，构造一个 DataFrame，指定 dataset 的数据源。
+
+例如，您可以创建一个 DataFrame 来保存来自表、外部 CSV 文件、本地数据或 SQL 语句执行的数据。
+
+2，指定如何转换DataFrame中的数据集。
+
+例如，您可以指定应该选择哪些列、如何过滤行、如何对结果进行排序和分组等。
+
+3，执行语句将数据检索到 DataFrame 中。
+
+为了将数据检索到 DataFrame 中，您必须调用执行操作的方法（例如，方法 collect()）。
+```
+
+本示例使用 DataFrame 来查询名为 `sample_product_data` 的表。如果要运行这些示例，您可以创建该表，并通过执行以下 SQL 语句向该表插入一些数据。
+
+```python
+session.sql('CREATE  TABLE if not exists sample_product_data (id INT, parent_id INT, category_id INT, name STRING, serial_number STRING, key INT, third INT)').collect()
+```
+
+```
+[Row(result_message='OPERATION SUCCEED')]
+```
+
+```python
+session.sql('CREATE  TABLE if not exists sample_product_data_varchar (id INT, parent_id INT, category_id INT, name STRING, serial_number VARCHAR, key INT, third INT)').collect()
+```
+
+```
+[Row(result_message='OPERATION SUCCEED')]
+```
+
+```python
+session.sql("""
+... INSERT INTO sample_product_data_varchar VALUES
+... (1, 0, 5, 'Product 1', 'prod-1', 1, 10),
+... (2, 1, 5, 'Product 1A', 'prod-1-A', 1, 20),
+... (3, 1, 5, 'Product 1B', 'prod-1-B', 1, 30),
+... (4, 0, 10, 'Product 2', 'prod-2', 2, 40),
+... (5, 4, 10, 'Product 2A', 'prod-2-A', 2, 50),
+... (6, 4, 10, 'Product 2B', 'prod-2-B', 2, 60),
+... (7, 0, 20, 'Product 3', 'prod-3', 3, 70),
+... (8, 7, 20, 'Product 3A', 'prod-3-A', 3, 80),
+... (9, 7, 20, 'Product 3B', 'prod-3-B', 3, 90),
+... (10, 0, 50, 'Product 4', 'prod-4', 4, 100),
+... (11, 10, 50, 'Product 4A', 'prod-4-A', 4, 100),
+... (12, 10, 50, 'Product 4B', 'prod-4-B', 4, 100)
+... """).collect()
+```
+
+```
+[Row(result_message='OPERATION SUCCEED')]
+```
+
+验证数据插入是否成功，请运行：
+
+```python
+session.sql("SELECT count(*) FROM sample_product_data_varchar").collect()
+```
+
+```
+[Row(`count`(*)=120)]
+```
+
+## 构建 DataFrame
+
+要构造 DataFrame，可以使用 Session 类的方法和属性。以下每种方法都从不同类型的数据源构造 DataFrame。
+
+要从表、视图或流中的数据创建 DataFrame，请调用以下 `table` 方法：
+
+```python
+# Create a DataFrame from the data in the "sample_product_data" table.
+df_table = session.table("sample_product_data")
+# To print out the first 10 rows
+df_table.show()
+```
+
+```
+---------------------------------------------------------------------------------------
+|`id`  |`parent_id`  |`category_id`  |`name`      |`serial_number`  |`key`  |`third`  |
+---------------------------------------------------------------------------------------
+|1     |0            |5              |Product 1   |prod-1           |1      |10       |
+|2     |1            |5              |Product 1A  |prod-1-A         |1      |20       |
+|3     |1            |5              |Product 1B  |prod-1-B         |1      |30       |

+---------------------------------------------------------------------------------------
+```
+
+要从指定数据创建 DataFrame，请调用 `create_dataframe` 方法：
+
+```python
+# Create a DataFrame with one column named a from specified values.
+df1 = session.create_dataframe([1, 2, 3, 4]).to_df("a")
+df1.show()
+
+```
+
+```
+-------
+|`a`  |
+-------
+|1    |
+|2    |
+|3    |
+|4    |
+-------
+```
+
+创建一个具有 4 列（“a”、“b”、“c”和“d”）的 DataFrame：
+
+```python
+df2 = session.create_dataframe([[1, 2, 3, 4]], schema=["a", "b", "c", "d"])
+df2.show()
+```
+
+```
+-------------------------
+|`a`  |`b`  |`c`  |`d`  |
+-------------------------
+|1    |2    |3    |4    |
+-------------------------
+```
+
+创建另一个包含 4 列（“a”、“b”、“c”和“d”）的 DataFrame：
+
+```python
+from clickzetta.zettapark import Row
+df3 = session.create_dataframe([Row(a=1, b=2, c=3, d=4)])
+df3.show()
+```
+
+```
+-------------------------
+|`a`  |`b`  |`c`  |`d`  |
+-------------------------
+|1    |2    |3    |4    |
+-------------------------
+```
+
+创建一个 DataFrame 并指定一个模式（Schema）：
+
+```python
+from clickzetta.zettapark.types import IntegerType, StringType, StructType, StructField
+schema = StructType([StructField("a", IntegerType()), StructField("b", StringType())])
+df4 = session.create_dataframe([[1, "click"], [3, "zetta"]], schema)
+df4.show()
+```
+
+```
+---------------
+|`a`  |`b`    |
+---------------
+|1    |click  |
+|3    |zetta  |
+---------------
+```
+
+要创建包含一系列值的 DataFrame，请调用以下 `range` 方法：
+
+```python
+df_range = session.range(1, 10, 2).to_df("a")
+df_range.show()
+```
+
+```
+-------
+|`a`  |
+-------
+|1    |
+|3    |
+|5    |
+|7    |
+|9    |
+-------
+```
+
+## 对指定数据集进行转换
+
+要指定选择哪些列以及如何对结果进行筛选、排序、分组等操作，请调用转换数据集的 DataFrame 方法。要标识这些方法中的列，请使用 `col` 函数或计算结果为列的表达式。
+
+例如：
+要指定应返回哪些行，请调用 `filter` 方法：
+
+```python
+from clickzetta.zettapark import functions as F
+```
+
+```python
+df = session.table("sample_product_data").filter(F.col("id") == 1)
+df.show()
+```
+
+```
+--------------------------------------------------------------------------------------
+|`id`  |`parent_id`  |`category_id`  |`name`     |`serial_number`  |`key`  |`third`  |
+--------------------------------------------------------------------------------------
+|1     |0            |5              |Product 1  |prod-1           |1      |10       |
+--------------------------------------------------------------------------------------
+```
+
+要指定应选择的列，请调用 `select` 方法：
+
+```python
+# Create a DataFrame that contains the id, name, and serial_number
+# columns in the "sample_product_data" table.
+df = session.table("sample_product_data").select(F.col("id"), F.col("name"), F.col("serial_number"))
+df.show()
+```
+
+```
+---------------------------------------
+|`id`  |`name`      |`serial_number`  |
+---------------------------------------
+|1     |Product 1   |prod-1           |
+|2     |Product 1A  |prod-1-A         |
+|3     |Product 1B  |prod-1-B         |
+|4     |Product 2   |prod-2           |
+|5     |Product 2A  |prod-2-A         |
+|6     |Product 2B  |prod-2-B         |
+|7     |Product 3   |prod-3           |
+|8     |Product 3A  |prod-3-A         |
+|9     |Product 3B  |prod-3-B         |
+|10    |Product 4   |prod-4           |
+---------------------------------------
+```
+
+```python
+# Import the col function from the functions module.
+df_product_info = session.table("sample_product_data")
+df1 = df_product_info.select(df_product_info["id"], df_product_info["name"], df_product_info["serial_number"])
+df2 = df_product_info.select(df_product_info.id, df_product_info.name, df_product_info.serial_number)
+df3 = df_product_info.select("id", "name", "serial_number")
+```
+
+## 连接DataFrame
+
+要连接 DataFrame 对象，请调用 `join` 方法：
+
+```
+# Create two DataFrames to join
+df_lhs = session.create_dataframe([["a", 1], ["b", 2]], schema=["key", "value1"])
+df_rhs = session.create_dataframe([["a", 3], ["b", 4]], schema=["key", "value2"])
+# Create a DataFrame that joins the two DataFrames
+# on the column named "key".
+df_lhs.join(df_rhs, df_lhs.col("key") == df_rhs.col("key")).select(df_lhs["key"].as_("key"), "value1", "value2").show()
+```
+
+```
+-------------------------------
+|`key`  |`value1`  |`value2`  |
+-------------------------------
+|a      |1         |3         |
+|b      |2         |4         |
+-------------------------------
+```
+
+```python
+import copy
+
+df = session.table("sample_product_data")
+# This fails because columns named "id" and "parent_id"
+# are in the left and right DataFrames in the join.
+df_copy = copy.copy(df)
+df_joined = df.join(df_copy, F.col("id") == F.col("parent_id"))
+```
+
+## 指定列和表达式
+
+调用这些转换方法时，您可能需要指定列或使用列的表达式。例如，调用 `select` 方法时，您需要指定要选择的列。
+
+```python
+df_product_info = session.table("sample_product_data").select(F.col("id"), F.col("name"))
+df_product_info.show()
+```
+
+```
+---------------------
+|`id`  |`name`      |
+---------------------
+|1     |Product 1   |
+|2     |Product 1A  |
+|3     |Product 1B  |
+|4     |Product 2   |
+|5     |Product 2A  |
+|6     |Product 2B  |
+|7     |Product 3   |
+|8     |Product 3A  |
+|9     |Product 3B  |
+|10    |Product 4   |
+---------------------
+```
+
+在指定过滤器、投影、连接条件等时，可以在表达式中使用 Column 对象。例如：
+您可以使用 Column 对象和 `filter` 方法来指定过滤条件：
+
+```python
+# Specify the equivalent of "WHERE id = 20"
+# in a SQL SELECT statement.
+df_filtered = df_product_info.filter(F.col("id") == 20)
+df_filtered.show()
+```
+
+```
+-----------------
+|`id`  |`name`  |
+-----------------
+|      |        |
+-----------------
+```
+
+```python
+df = session.create_dataframe([[1, 3], [2, 10]], schema=["a", "b"])
+# Specify the equivalent of "WHERE a + b < 10"
+# in a SQL SELECT statement.
+df_filtered = df.filter((F.col("a") + F.col("b")) < 10)
+df_filtered.show()
+```
+
+```
+-------------
+|`a`  |`b`  |
+-------------
+|1    |3    |
+-------------
+```
+
+## 关闭会话
+
+```Python
+session.close()
+```

+# 基于 Lakehouse Zettapark 进行数据工程 Data Engineering
+
+这是一个非常基础的数据工程示例，演示了如何通过云器 Zettapark Python 代码进行读取、分组和写入数据等基本 DataFrame 操作。本示例使用云器Lakehouse内置的免费示例数据库（clickzetta\_sample\_data.tpch\_100g）作为数据源。
+
+步骤如下：
+
+```
+1，通过Zettapark连接到云器Lakehouse
+
+2，通过SupplierKey连接 2个大型表 (LINEITEMS 有 6亿行 & SUPPLIER 有 100 万行)
+
+3，通过将虚拟计算集群调整到不同规格来演示按需扩展
+
+4，对比不同规格的虚拟计算集群对同一个任务的执行时间的不同
+
+    汇总供应商和零件编号的数据以计算总和、最小值和最大值（3500万行）
+
+    将结果数据框写入云器Lakehouse物理表（8000万行）
+```
+
+也可以通过[下载Jupyter Notebook文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/Zettapark/Zettapark_Data_Engineering_Demo.ipynb)直接运行本实例。
+
+**整个操作从调整计算资源、读取数据、连接、汇总大约需要 30 来秒，向您展示了云器 Lakehouse 强大的功能、即时可扩展性和性能。**
+
+## 安装云器 Zettapark
+
+```python
+# !pip install clickzetta-zettapark-python
+```
+

+# 配置访问控制
+
+本文介绍如何在云器Lakehouse中为账户和元数据对象配置访问控制策略。通过合理配置访问控制，你可以确保数据与对象的访问仅限于授权用户与角色，符合最小权限原则，提升系统安全性。
+
+## 服务实例级管理
+
+### 为服务实例（instance）指定额外的管理员用户
+
+在云器Lakehouse中，创建服务实例的用户默认拥有“实例管理员”（instance\_admin）角色。为确保至少有一名用户可执行实例层面的管理任务（如创建工作空间、管理实例级角色），当你移除被授予“实例管理员”（instance\_admin）角色的用户时至少需要保留一名用户，否则会收到报错提示。建议至少再指定一名用户为实例管理员，以避免因用户不可用或其他特殊情况造成的影响。
+
+^
+
+### 授予实例级别角色
+
+服务实例级别的角色仅支持通过Web端方式授予。仅具备“服务实例管理员”（instance\_admin）角色的用户可进行此操作。
+
+在服务实例中，依次打开“管理”->“安全”菜单，点击进入，并切换到“角色”页面。
+
+:-: ![](.topwrite/assets/image_1734853864093.png =791)
+
+点击需要授予的服务实例角色，进入该角色的详情页面，点击“用户授予”：
+
+:-: ![](.topwrite/assets/image_1734853972562.png =793)
+
+在弹窗中勾选需要授予的用户，点击“授权”按钮，即可完成实例角色的授予。
+
+^
+
+## 工作空间级管理
+
+### 指定工作空间（workspace）管理员
+
+创建工作空间（workspace）的用户默认拥有该工作空间的"工作空间管理员（workspace\_admin）"角色，该角色具备管理工作空间内的所有权限。每个工作空间内至少需要有一名用户被授予工作空间管理员角色，可以有多个用户被同时授予。
+
+### 管理工作空间内角色和成员
+
+每个工作空间内的角色和成员是与其他工作空间独立的，需要单独授予。仅一个工作空间的工作空间管理员（workspace\_admin）角色，可以管理该工作空间内的角色授予、创建、删除，以及空间内成员的添加、移除。
+
+#### 管理空间成员
+
+一个用户若要在指定工作空间内使用计算集群（Vcluster）和执行SQL，其前提条件是加入该工作空间。工作空间管理员可以通过以下两种方式将指定用户加入工作空间中：
+
+**Web端操作**
+
+进入服务实例后，依次点击菜单中的“管理”-“工作空间”，进入工作空间列表。点击工作空间名称，进入需要添加成员的工作空间详情。
+
+:-: ![](.topwrite/assets/image_1734854163713.png =795)
+
+在工作空间详情页点击“+ 添加用户” 按钮，在弹窗中选择需要添加的用户。只有服务实例中已存在且当前未加入此工作空间的用户才会在列表中显示。勾选一到多名用户，随后点击“添加用户”或“添加用户并授予角色”按钮，将已选择用户添加进入工作空间。成功添加后，可在工作空间的“用户”列表中找到新添加的用户。
+
+在工作空间的“用户”列表中，点击某一用户右侧操作列的“...”，选择“移除用户”，将从工作空间中移除该用户。被移除的用户将立即失去被授予的空间角色，并失去使用工作空间内计算集群（Vcluster）和在该工作空间内执行SQL的权限。
+
+:-: ![](.topwrite/assets/image_1734876545148.png =788)
+
+请注意，从工作空间移除的用户，仍将具备被直接授予给用户的数据权限，即可以在其他工作空间行使被授予的数据权限，对数据进行查询或变更。因此，推荐通过授予角色的方式来管理权限，以降低此类场景带来的权限管理难度。
+
+**SQL操作**
+
+通过JDBC连接工作空间，为工作空间添加用户时执行以下语句：
+
+```SQL
+CREATE USER <user_name>;
+```
+
+\<user\_name>替换为需要加入工作空间的用户名。仅支持添加服务实例中已存在且当前没有加入此工作空间的用户。
+
+从工作空间移除用户执行以下语句：
+
+```SQL
+DROP USER <user_name>;
+```
+
+\<user\_name>替换为需要移除工作空间的用户名。该操作不会删除此用户身份，只会从当前工作空间中移除此用户。
+
+### 使用工作空间级别角色
+
+#### 在工作空间内进行开发
+
+在工作空间中进行开发需要：具备在工作空间中执行SQL的权限（成为工作空间成员后获得）；具备使用工作空间中计算资源的权限；具备需要操作的数据对象的权限。
+
+在每个工作空间中预置了以下角色默认具备以上的一种或多种权限，可将以下角色授予用户，以快速开始数据开发。
+
+**工作空间开发者（workspace\_dev）角色**
+
+workspace\_dev角色默认具备工作空间内所有数据对象（table、view、dynamic table等，详见'元数据对象'）的读写权限，默认具备工作空间内所有计算集群的使用权限。
+
+用户被授予workspace\_dev角色后，可直接在Web页面的"开发"功能内或使用JDBC协议进行数据开发。
+
+注意，workspace\_dev角色默认具备的数据对象读写权限并不支持其将权限二次授权。如需授予其他角色数据对象的读或写权限，请使用具备工作空间管理员（workspace\_admin）角色的用户进行操作。
+
+**数据分析师（workspace\_analyst）角色**
+
+workspace\_analyst角色默认具备工作空间内所有计算集群的使用权限，默认具备工作空间内所有数据对象（table、view、dynamic table等）的read metadata（元数据查看）权限，但是不具备数据对象的select权限，即不能对任何的表或视图执行select查询。使用workspace\_analyst角色进行数据查询分析时，需要授予workspace\_analyst角色要查询数据对象的select权限，以执行数据查询操作。
+
+对workspace\_analyst角色的数据授权操作，请参考“GRANT”语句操作文档。
+
+**使用自定义角色或用户**
+
+自定义角色和用户通过授权，也可在工作空间中执行SQL语句进行开发或数据查询分析，但无法使用Web端的“开发”功能。对自定义角色和用户的授权需要具备workspace\_admin角色的用户进行操作。授权可参考以下语句：
+
+```SQL
+--将工作空间内所有计算集群的使用和元数据查看权限授予自定义角色
+GRANT USE, READ METADATA ON ALL VCLUSTERS TO ROLE <CUSTOM_ROLE_NAME>;
+--[可选]将指定名称的计算集群的使用和元数据查看权限授予自定义角色
+GRANT USE, READ METADATA ON  VCLUSTER <VCLUSTER_NAME> TO ROLE <CUSTOM_ROLE_NAME>;
+
+--将指定名称的schema下所有对象的select和元数据查询权限授予自定义角色
+GRANT SELECT, READ METADATA ON ALL OBJECTS IN SCHEMA <SCHEMA_NAME> TO ROLE <CUSTOM_ROLE_NAME>;
+--将指定table的select和元数据查询权限授予自定义角色
+GRANT SELECT, READ METADATA ON TABLE <TABLE_NAME> TO ROLE <CUSTOM_ROLE_NAME>;
+```
+
+对用户授权时，将上述语句中的 TO ROLE <CUSTOM_ROLE_NAME> 替换为 TO USER <USER_NAME> 即可。
+
+#### 提交并运维工作空间调度任务
+
+在工作空间中提交调度任务只能在Web端的“开发”功能中完成。workspace\_admin(工作空间管理员)和workspace\_dev（工作空间开发者）角色具备“提交”作业脚本成为调度任务的权限。
+
+:-: ![](.topwrite/assets/image_1734876961826.png =802)
+
+^
+
+工作空间中运维调度任务的系统角色为：workspace\_sre（工作空间运维）。具备该角色的用户，可在“运维监控”菜单下的“**任务运维**”和”**监控报警**“功能以及”数据“菜单下的”**数据质量**“功能中，对其所在空间的调度任务进行管理操作。
+
+workspace\_sre（工作空间运维）角色具备该角色所在工作空间下所有调度任务的运维管理权限，不具备工作空间下的计算资源使用和数据对象查询权限。
+
+如需对服务实例内所有工作空间的调度任务进行统一管理，可对用户授予实例级别角色：instance\_sre（实例运维）角色。该角色的权限是服务实例内所有workspace\_sre角色默认权限的并集。
+
+#### 创建自定义角色
+
+为实践“最小权限原则”，建议根据你的组织业务职能划分创建自定义角色，并为其分配针对特定对象和操作的权限。这样，你可以精确控制用户对特定数据或对象的访问范围。
+
+创建自定义角色的一般流程：
+
+1. 创建自定义角色（CREATE ROLE语句）。
+2. 为该角色授予所需的权限点（GRANT语句）。
+3. 将该角色授予给需要相关权限的用户（GRANT ROLE语句或Web端操作）。
+
+**注意**：云器Lakehouse中，角色不能被授予给其他角色，即不支持角色层次结构（Role Hierarchy）。所有角色最终直接授予给用户，避免了因角色间的层级继承关系而带来的、判断具体用户权限范围的复杂度。
+
+#### 授予或移除用户的角色
+
+你可以使用Web或执行授权SQL的操作方式向用户授予或移除角色。仅具备服务实例管理员（instance\_admin）或工作空间管理员（workspace\_admin）角色的用户，可以为用户授予或移除角色。服务实例管理员（instance\_admin）具备向服务实例内所有用户授予实例级别角色的权限；工作空间管理员（workspace\_admin）具备向工作空间内成员授予空间内角色的权限。
+
+**Web端操作**
+
+在“安全”-“角色”页面，可以查看当前实例下的服务实例级别角色和工作空间级别角色。
+
+:-: ![](.topwrite/assets/image_1734878372389.png =784)
+
+服务实例管理员（instance\_admin）角色可查看所有的实例级别角色和所有工作空间级别角色，可管理所有实例级别角色的授权；
+
+工作空间管理员（workspace\_admin）角色可查看本工作空间内的所有工作空间角色，并管理这些角色的授权。如一个用户同时具备多个工作空间的工作空间管理员（workspace\_admin）角色，则可以同时管理多个工作空间内的角色授权。
+
+对任一角色授权时，点击该角色名称，进入角色详情页，此时可以查看该角色已被授予的所有用户。点击“+ 用户授予”，在弹窗中勾选需要添加的用户，点击“授权”，即可将角色授予用户。
+:-: ![](.topwrite/assets/image_1734878510613.png =798)
+
+移除角色被授予的用户时，点击用户名右侧的"..."，选择“移除用户”，即可取消该用户使用这个角色的权限。
+
+在“管理”-“工作空间”列表进入工作空间详情页面，在“角色”页签也可以查看该空间内的角色列表，并通过上述操作将该角色授予或取消授予用户。
+
+:-: ![](.topwrite/assets/image_1734878871234.png =795)
+
+***
+
+**SQL端操作**
+
+仅工作空间级别的用户支持使用SQL操作进行授权。在工作空间内执行以下语句，可将空间内的角色授予指定用户。
+
+```SQL
+Grant ROLE <ROLE_NAME> TO USER <USER_NAME>;
+```
+
+执行以下语句可移除角色中的指定用户；
+
+```SQL
+REVOKE ROLE <ROLE_NAME> FROM USER <USER_NAME>;
+```
+
+### 示例：创建自定义角色并授予权限
+
+**提示**：当前暂不支持在 Web 端创建自定义角色和对自定义角色授权。你需要使用 SQL 创建自定义角色。
+
+假设你希望创建一个空间级角色r1，用于管理特定schema s1下的一张表t1。为此，需要为r1授予：
+
+* 对计算集群（假设名称为v1）的使用权限（USAGE）。
+* \[可选] 计算集群（假设名称为 v1）的 READ METADATA 权限，以在计算集群页面或 SHOW VCLUSTERS 结果中可见这个计算集群；
+* 对表s1.t1的ALL权限，以对表执行select、insert、update、alter等操作。
+
+#### 创建自定义角色
+
+```
+CREATE ROLE r1;
+```
+
+#### 为角色授予权限
+
+```
+-- 为r1角色授予对计算集群（假设名称为v1）的使用权限（USAGE）
+GRANT use ON VCLUSTER v1 TO ROLE r1;
+--[可选]为r1角色授予对计算集群（假设名称为v1）的read metadata权限
+GRANT read metadata ON VCLUSTER v1 TO ROLE r1;
+
+
+--为r1角色授予对表s1.t1的所有权限
+GRANT all ON table s1.t1 to ROLE r1;
+
+```
+
+#### 将角色授予给用户
+
+```
+GRANT ROLE r1 TO USER u1;
+```
+
+### 示例：创建只读角色
+
+若你需要一个角色仅能对某schema中所有表进行查询（只读访问），可按照与创建自定义角色相同的流程操作。区别在于这个场景下仅授予表的SELECT和READ METADATA权限，而不包含任何写入、修改、删除等权限。同时，这里使用 `ALL TABLES IN SCHEMA s1` 来表达 s1 下当前和未来的所有 table 对象，以简化授权表达。
+
+例如，为read\_only角色授予schema s1下所有表的SELECT和READ METADATA权限：
+
+```
+GRANT SELECT, READ METADATA ON ALL TABLES IN SCHEMA s1 TO ROLE read_only;
+```
+
+请注意，如果read\_only角色没有计算集群的使用权限，此时无法使用计算资源对table执行查询。所以还需要至少授予该角色1个计算集群（vcluster）的使用权限。
+
+例如，为read\_only角色授予名称为demo\_vcluster的计算集群的使用权限。
+
+```
+GRANT USE ON VCLUSTER demo_vcluster TO ROLE read_only;
+```
+
+### 查看已授予的权限
+
+使用SHOW GRANTS命令可查看某对象或角色的当前权限状况。例如：
+
+```
+-- 查看schema d1.s1上的已授予权限
+SHOW GRANTS ON SCHEMA d1.s1;
+
+-- 查看角色r1获得的权限
+SHOW GRANTS TO ROLE r1;
+
+-- 查看用户smith获得的权限和角色
+SHOW GRANTS TO USER smith;
+```

+# 访问控制概览
+
+本文介绍了云器Lakehouse的访问控制总体框架和关键概念。通过了解访问控制的核心原理和相关要素，用户与管理员可在云器Lakehouse平台中安全、灵活地分配与管理权限，从而确保数据与元数据对象的合规使用。
+
+## 1. 访问控制模型
+
+云器Lakehouse采用灵活的访问控制机制，支持两种主要模型：
+
+* **访问控制列表（ACL）**： 将权限直接分配给用户（User）。在小型或简单场景中，这种方式较为直观；但在大型环境中，管理难度会随用户数量及权限需求增加而上升。
+
+:-: ![](.topwrite/assets/ACL.png =391)
+
+* **基于角色的访问控制（RBAC）**： 首先为角色（Role）分配权限，然后将角色授予用户，从而实现权限的间接管理。RBAC有助于简化复杂环境下的权限维护。当业务需求变化时，只需在角色层面调整权限，而无需为每个用户单独维护。
+
+:-: ![](<.topwrite/assets/Untitled Diagram.drawio.png> =460)
+
+与传统的DAC（Discretionary Access Control）不同，云器Lakehouse不直接支持在对象所有者基础上继续二次授权的DAC模式。建议采用RBAC，对权限进行集中、可控的统一管理。
+
+在云器Lakehouse中，RBAC和ACL的授权方式是并存的。一个用户可以同时被直接授予多个权限，并同时被授予多个角色。当该用户在执行任何操作时，其权限范围均为其被“直接授予的权限”和“被授予的角色”权限之和。用户无需声明其当前以何种身份或角色行使操作，鉴权系统将遍历该用户所有当前拥有的权限并给出鉴权结果。
+
+## 2. 对象及其所有权
+
+### 对象（Object）
+
+元数据对象是可被授予权限的实体，包括工作空间（workspace）、schema、table、view、virtual cluster等。这些对象在创建后默认由创建者拥有其全部权限，但无法依此进行二次授权。访问对象时，如果未被显式授权，则默认拒绝。
+
+云器Lakehouse中所有的元数据对象，详见授权文档。
+
+### 对象所有权（Ownership）
+
+初始创建该对象的用户（user）拥有对象的所有权（ownership）。拥有对象的角色可以对对象执行包括修改、删除在内的全部操作。当前暂不支持对对象所有权的转移。
+
+为了实现更灵活的权限分配机制和更安全的访问控制，推荐通过角色权限体系，使用服务实例管理员（instance\_admin）角色和工作空间管理员（workspace\_admin）角色进行统一的授权方式管理对象访问。
+
+## 3. 角色层次与类型
+
+### 角色（Role）
+
+角色是权限的载体。当为角色分配权限点后，通过将该角色授予给用户，可实现权限的间接传递。当用户拥有多个角色时，其权限为这些角色权限集合的并集。
+
+### 角色层次（Role Hierarchy）
+
+角色可分为两个层级范围：
+
+* **实例角色（Instance Role）**：用于实例级资源和操作的全局管控。
+* **工作空间角色（Workspace Role）**：作用于特定工作空间范围内的对象（如schema、table、virtual cluster等）。工作空间角色以工作空间为边界，互不影响。
+
+:-: ![](.topwrite/assets/role-levels.drawio.png =531)
+
+这种层次结构有助于在全局与局部范围实现精细的访问控制。当业务规模扩大、权限需求复杂时，可以通过在实例角色与工作空间角色间建立清晰的角色层次，简化权限分配。
+
+### 预置角色与自定义角色
+
+云器Lakehouse提供了若干预置角色（如实例管理员、数据源管理员、空间管理员等）以满足基础使用场景。用户还可在工作空间内创建自定义角色（通过SQL语句），从而灵活定义与调整符合自身业务需求的权限集。
+
+云器Lakehouse中所有的预置角色及其默认权限，详见授权文档。
+
+## 4. 权限及授权管理
+
+### 权限（Privilege）
+
+权限定义了对对象所能执行操作的最小访问单元，包括对表的查询、插入数据、对schema的管理或对虚拟集群的使用等。权限点可细粒度地定义用户对对象进行的读写改删操作。
+
+^
+
+云器Lakehouse中所有元数据对象及其权限点，详见授权文档。
+
+### 授权与回收（Grant & Revoke）
+
+使用 `GRANT` 与 `REVOKE` 命令对元数据对象授权或回收权限，权限变更即时生效。在Web界面中也可进行相应的可视化操作。
+
+示例：
+
+`GRANT SELECT ON TABLE my_table TO ROLE analyst_role;`
+
+`REVOKE INSERT ON TABLE my_table FROM ROLE analyst_role;`
+
+业务对象（如脚本、任务和数据质量规则）暂不支持SQL细粒度授权，其访问权限通过授予对应预置角色实现。
+
+## 无超级用户概念
+
+云器Lakehouse中不存在可绕过权限检查的超级用户（super-user）或超级角色（super-role）。所有访问操作都必须明确获得授权，确保数据访问的安全与合规。

+# 授权
+
+## 1. 访问控制模型
+
+云器Lakehouse的所有元数据对象均基于访问控制体系进行授权访问。云器Lakehouse支持的访问控制模型包括**访问控制列表**（ACL，Access Control List）和 **基于角色的访问控制**（RBAC，Role-Based Access Control）两种。
+
+* **访问控制列表**（**ACL，Access Control List**）
+
+权限点被直接授予用户（User）。
+
+* **基于角色的访问控制**（RBAC，Role-Based Access Control）
+
+权限点被授予角色（Role），用户通过被授予角色而获得相应的权限。
+
+* **DAC（Discretionary Access Control）模式兼容**
+
+云器Lakehouse不直接支持DAC模式。DAC模式指：元数据对象（table、view、virtual cluster等）的所有者（owner）默认拥有该元数据对象的所有权限，且可将权限授予其他主体。云器Lakehouse中的元数据对象被创建后，其创建者默认具备该对象的所有权限，但无法进行二次授权。
+
+^
+
+云器Lakehouse访问控制体系中的主要概念包括：
+
+* **元数据对象（Object）**
+
+元数据对象是一个可以被授出访问权限的实体。一个元数据对象包含多个权限点，除非通过明确授予允许，否则相关操作将被拒绝。
+
+* **角色（Role）**
+
+角色是一个可以被授予权限的实体。角色可以分配给用户，但不可以分配给其他角色。
+
+* **权限（Privilege）**
+
+权限是对元数据对象访问的最小定义级别。可以使用多个不同的权限点来控制授予操作的范围。
+
+* **用户（User）**
+
+用户是云器 Lakehouse 识别的用户身份，可以是用户身份或服务使用的身份。
+
+## 2. 角色
+
+### 2.1 角色类型
+
+云器Lakehouse中的角色两种：**预置角色**和**自定义角色**。
+
+为便于用户快速完成基本授权并使用产品功能，云器Lakehouse预置了多个角色。预置角色随服务实例创建而自动创建，不可修改权限或删除，但可以被授予用户。
+
+用户可根据自身需要，创建自定义角色，并对该角色授权。自定义角色可随时修改角色的属性、权限范围或删除。目前仅限在工作空间内创建自定义角色，不支持创建实例级别的自定义角色。
+
+### 2.2 角色级别
+
+云器Lakehouse的元数据对象分为“服务实例”（Instance）和“工作空间”（workspace）两个级别，角色也对应分为“实例角色”和“空间角色”两个级别。两个级别的对象没有从属关系，实例级别的角色不具备且不可被授予工作空间级别任何元数据对象（空间用户、空间角色、schema、table、计算集群等）的任何权限。
+
+空间角色以工作空间（workspace）为隔离边界。不同工作空间内，允许存在同名的角色。不同工作空间之间，不允许跨空间将权限授予另一工作空间角色。
+
+### 2.3 预置系统角色
+
+当前系统内预置的角色及权限如下表所示：
+
+|          |          |                    |                                                                                          |                                                        |                                 |

+
+### 2.4 用户自定义角色
+
+当前仅支持在工作空间内，使用SQL语法创建自定义角色。创建自定义角色的语法为：
+
+```Plain
+CREATE ROLE <role_name>;
+```
+
+仅被授予工作空间的空间管理员角色（workspace\_admin）的用户，可在工作空间内创建自定义角色，并可随时对自定义角色进行权限管理和删除操作。
+
+## 3. 权限（Privileges）
+
+### 3.1 权限定义
+
+访问控制权限的授予决定了用户可以对特定对象执行指定操作。对于云器Lakehouse中的每个元数据对象对象，都有一组可以授予的权限。云器Lakehouse中的所有元数据对象及其拥有的权限点，详见 权限点 文档。
+
+元数据对象有三种表达方式：
+
+1）以对象类型加对象名称，表达已被创建的对象。例如：table mytable（名称为mytable的表） 或 vcluster myvcluster（名称为myvcluster的计算集群）；
+
+2）以关键字ALL 加对象类别，表达现有和未来所有该类型的对象。例如：ALL tables in schema my\_schema （名称为my\_schema的schema下的所有table类型对象）；
+
+3）以关键字ALL 加关键字 OBJECTS 表达现有和未来的所有类型的所有对象，例如：ALL OBJECTS in workspace my\_workspace（名称为my\_workspace的工作空间下所有的对象）。
+
+权限点有两种表达方式：
+
+1）以具体权限点表达，例如：select，read metadata，update 等；
+
+2）以关键字ALL加关键字PRIVILEGES，表达所有权限点，例如：ALL PRIVILEGES on table mytable（mytable表的所有权限点）。
+
+在使用SQL语句进行权限管理时，使用 GRANT <权限点> 和 REVOKE <权限点> 命令。在GRANT <权限点>语句末尾加上with grant option，表示在授予该权限点的同时，将允许被授予者将该权限点再授予其他角色或用户。
+
+### 3.2 元数据对象
+
+Lakehouse中的元数据对象及其父级对象如下表所示：
+
+|                   |           |
+| ----------------- | --------- |
+| **元数据对象**         | **父级对象**  |
+| workpace          | instance  |
+| share             | instance  |
+| network policy    | instance  |
+| schema            | workspace |
+| virtual cluster   | workspace |
+| connction         | workspace |
+| table             | schema    |
+| view              | schema    |
+| materialized view | schema    |
+| dynamic table     | schema    |
+| table stream      | schema    |
+| volume            | schema    |
+| index             | schema    |
+| function          | schema    |
+| job               | schema    |
+
+元数据对象均可以通过SQL进行授权。
+
+### 3.3 业务对象
+
+除元数据对象外，在数据开发、数据治理过程中，产生了业务对象，如下表所示：
+
+|                    |                       |
+| ------------------ | --------------------- |
+| **业务对象**           | **业务类别**              |
+| 脚本（Script）         | 数据开发  （Development）   |
+| 任务和实例（task）        | 监控规则（monitor rules）   |
+|                    | 通知策略（announce policy） |
+| 数据质量（data quality） | 质量规则（dqc rule）        |
+
+业务对象不可通过SQL进行授权。用户通过被授予包含业务对象权限的预置角色来获取相关权限。暂不支持细粒度授权。
+
+### 3.4 ALL 对象
+
+ALL 对象是一种特殊的对象，表达一类对象下**当前**和**未来**的所有个体。例如：all tables表达当前和未来的所有table；all vclusters表达当前和未来的所有计算集群。
+
+通过`ALL`关键字可以一次性为对象集合（如某schema下的所有表）授予权限，从而减少繁琐的重复授权操作。同时，ALL关键字提供“Future Grants”（未来授权）机制，例如：`all tables in schema s1` 表示schema s1内当前和未来可能新增的所有table类型对象。
+
+ALL 对象在使用时，需要和关键字“in”一起使用，以明确ALL 对象描述的范围，关键字“in”之后跟随的是ALL 对象的父级对象。例如：all tables in schema my\_schema; all vclusters in workspace my\_workspace。
+
+ALL 对象的一种特殊用法是用于指代某父级对象下的所有自级对象，例如：all objects in schema my\_schema，表达my\_schema下的所有类型对象，包括table、view、functions等。
+
+注意：尽管ALL对象可以提升授权操作的效率，但请谨慎使用all objects的方式授权。仅在确认all objects指代的范围符合授权预期时，再使用all objects进行指代，避免授权范围超出预期。
+
+^
+
+### 3.5 权限点
+
+元数据对象的所有操作类型如下：
+
+|                  |          |                                                  |

+
+业务对象的所有操作类型如下：
+
+| **对象**                | **包含操作**                                                                                  |

+
+每个操作都与一个唯一的权限点相对应。当被授予某个对象的某权限点时，即可对该对象执行对应的操作。
+
+### 3.6 ALL 权限点
+
+ALL 权限点是各类元数据对象上均存在的一个权限点，表达该对象的所有权限点。ALL权限点是一个**独立**的权限点，与其他权限点并非指代关系。因此授予ALL权限点不会覆盖授予其他权限点，解除ALL权限点也不会解除其他权限点。
+
+例如：对user my\_user 先后授予了example\_table的select和ALL权限点。则此时my\_user用户由于被授予了ALL权限点，可以对example\_table执行所有操作；在查询my\_user用户对example\_table的权限时，显示同时拥有的select和all权限点的授权。当对my\_user用户解除ALL权限点的授权时，my\_user用户仍具备对example\_table进行select操作的权限。
+
+使用ALL权限点可以快速完成对一个对象所有权限的授予，例如：
+
+```SQL
+Grant all privileges on table example_table to user my_user;
+```
+
+## 4. 授权（Grants）
+
+### 4.1 授权定义
+
+授权的基本模型是将“**对象**”的“**权限点**”授予“**身份**”。其中对象可以是元数据对象或业务对象，权限点是这个对象包含的一个或多个权限点，身份目前指“用户（user）”和“角色（role）”两种。
+
+### 4.2 授权关系管理
+
+一个用户（user）可以通过两种方式获得某个对象的权限：1）直接被授予该对象的权限；2）通过被授予拥有该对象权限的角色获得。
+
+当一个用户同时被授予多个角色时，该用户的权限范围是多个角色权限范围的并集。
+
+角色不允许被授予给角色。
+
+### 4.3 查看授权
+
+支持以被授予身份和被授权对象两个角度来查看授权。
+
+从被授权身份角度查看，例如：show grants to user my\_user; 将显示该用户被授予的所有角色，以及被**直接**授予的权限。
+
+从被授权对象角度查看，例如：show grants on table my\_table; 将显示该对象所有被授出的权限，包含授予用户的和角色的。
+
+### 4.4 授权操作
+
+元数据对象的授权操作，可以使用SQL操作，详见GRANT和REVOKE语句的相关介绍。也可以在“管理”-“安全”-“权限”页面中进行Web端操作。
+
+业务对象的授权目前仅支持通过授予预置角色的方式授予，暂不支持单独对业务对象授权。

+# 管理用户
+
+本文介绍如何在账户中添加更多用户并管理这些用户。
+
+具备账户管理员角色的用户，可以通过管理中心的“用户管理”功能对账户下的用户进行管理操作。您可以通过页面导航进入该功能页面。
+
+## 配置账号管理员
+
+仅具备账户管理员（Account\_admin）角色的用户可以对全局用户进行创建和维护。创建云器账户的第一个用户，默认被授予账户管理员角色。
+
+具备账户管理员（Account\_admin）角色的用户可以配置其他用户成为账户管理员角色。账户管理员角色可授予一名或多名用户，但账户中至少需要有一名用户拥有此角色。为避免因账户管理员用户登录异常而影响业务操作，建议至少配置两名用户担任账户管理员角色。
+
+管理账户管理员角色的操作步骤如下：
+
+1. 登录后，在<您的account\_name>.accounts.clickzetta.com/workbench页面点击“用户管理”，找到需要设置为账户管理员的用户，点击其右侧的“...”按钮展开操作菜单，然后点击“编辑”。
+
+:-: ![](.topwrite/assets/image_1735043871476.png =805)
+
+2. 在弹窗中的“设为账户管理员”一栏中选择“是”，然后点击“保存”。
+
+:-: ![](.topwrite/assets/image_1735043951355.png =365)
+
+3. 账户管理员可以移除其他用户的“账户管理员”角色。操作与授予账户管理员角色类似，在用户的“编辑”弹窗中，将“设为账户管理员”一栏选择为“否”即可。
+
+## 用户管理
+
+### 创建全局用户
+
+具备账户管理员角色的用户在“用户管理”页面点击“新建用户”按钮，填写新用户的用户名、密码和手机号等信息后，即可创建全局用户。
+
+:-: ![](.topwrite/assets/image_1735044006849.png =790)
+
+:-: ![](.topwrite/assets/image_1735045263309.png =426)
+
+### 编辑全局用户信息
+
+在“用户管理”页面，找到需要编辑的用户，点击其右侧的“...”按钮展开操作菜单，然后点击“编辑”按钮，即可编辑用户信息。仅可修改用户的邮箱信息，以及设置该用户是否具有“账户管理员”角色。为保障系统安全，账户管理员不可修改其他用户的密码和手机号信息。
+
+:-: ![](.topwrite/assets/image_1735044079989.png =780)
+
+### 禁用全局用户
+
+禁用全局用户将立即改变该用户的状态，并禁止以该用户身份进行的所有操作。禁用全局用户可用于在识别出安全风险后，紧急停止该用户的所有操作，避免损失扩大。
+
+仅账户管理员角色的用户可以禁用全局用户。在“用户管理”页面，找到需要禁用的用户，点击其右侧的“...”按钮展开操作菜单，然后点击“禁用”按钮，二次确认后即可禁用该用户。
+
+### 启用全局用户
+
+仅“禁用”状态下的用户可被启用。在“用户管理”页面，找到需要启用的用户，点击其右侧的“...”按钮展开操作菜单，然后点击“启用”按钮即可启用该用户。
+
+### 删除全局用户
+
+在“用户管理”页面，找到需要删除的用户，点击其右侧的“...”按钮展开操作菜单，然后点击“删除”按钮。在弹窗中输入该用户的用户名以确认删除。删除用户并不会主动使该用户的登录会话失效或断开以此用户身份建立的JDBC连接。但当此用户在Web端进行任意操作，或使用JDBC连接执行任意请求时，会返回身份失效信息。
+
+### 修改用户密码
+
+账户管理员不可代其他用户修改其密码，仅当前登录用户可修改自己的密码。用户登录状态下，点击左下角的用户名，然后点击“修改密码”。在弹窗中完成验证码验证后，输入新密码即可完成密码修改。修改后的密码在下次登录时生效，不影响当前登录状态。
+
+### 修改用户手机号
+
+账户管理员不可代其他用户修改其手机号，仅当前登录用户可修改自己的手机号。用户登录状态下，点击左下角的用户名，然后点击“用户信息”按钮，打开用户信息弹窗。在手机号右侧点击“编辑”按钮，在弹窗中依次验证当前手机号并输入新手机号，即可完成手机号修改。
+
+^
+
+## 服务用户管理
+
+### 创建自定义服务用户
+
+具备账户管理员角色的用户在“用户管理”页面点击“新建自定义服务用户”按钮，填写服务用户的用户名和密码即可新建自定义服务用户。
+
+:-: ![](.topwrite/assets/image_1735045434327.png =475)
+
+^
+
+### 修改服务用户密码
+
+具备“账户管理员”角色的用户可以修改服务用户的密码。由于修改自定义服务用户密码属于敏感操作，需要验证**当前登录用户**的手机号，正确输入短信验证码后方可修改。
+
+:-: ![](.topwrite/assets/image_1735045692635.png =472)
+
+^
+
+### 禁用服务用户
+
+禁用服务用户将立即改变该服务用户的状态，并禁止使用该服务用户身份进行的所有操作。
+
+仅具备账户管理员角色的用户可以禁用服务用户。在“用户管理”页面，找到需要禁用的服务用户，点击其右侧的“...”按钮展开操作菜单，然后点击“禁用”按钮，二次确认后即可禁用该服务用户。
+
+:-: ![](.topwrite/assets/image_1735045875934.png =810)
+
+### 删除服务用户
+
+在“用户管理”页面，找到需要删除的服务用户，点击其右侧的“...”按钮展开操作菜单，然后点击“删除”按钮。在弹窗中输入该服务用户的用户名以确认删除。
+
+由于服务用户身份通常被关联在系统调度任务或其他应用任务中，删除正在使用的服务用户可能导致生产任务中断或造成故障，因此删除服务用户的弹窗提供了是否“强制删除”的勾选框：
+
+:-: ![](.topwrite/assets/image_1735046163259.png =627)
+
+* 如不勾选“强制删除”，则该服务用户身份将被“软删除”，所有使用该服务用户身份进行的任务将中断。但该服务用户仍将保留24小时。在此期间，可点击“恢复”按钮将其状态恢复为“正常”。恢复后，使用该服务用户的任务可重新正常执行（若任务因无重试机制或超过重试次数而失败，可能需要手动启动）。24小时后，该服务用户身份将被永久删除，不可恢复。
+
+:-: ![](.topwrite/assets/image_1735046443500.png =799)
+
+* 如勾选“强制删除”，则不提供保留期，直接删除该服务用户身份。

+# 监控告警
+
+## 简介
+
+监控告警系统为您提供了强大的监控任务运行状态和异常情况的功能。通过使用系统内置的规则或创建自定义规则，您可以实时监控任务运行状态，并在发生异常时接收告警信息。本指南将帮助您了解监控告警系统的核心概念、功能和操作步骤。
+
+## 核心概念
+
+1. **系统消息**：系统内部产生的全量消息，包含产品、模块、对象和消息内容等关键属性。系统消息是监控规则和告警事件的基础。
+2. **监控规则**：用户定义的一组配置信息，用于筛选关注的关键系统消息。监控规则帮助您确定哪些消息需要关注。
+3. **告警事件**：基于监控规则筛选出的系统消息。告警事件将显示在产品界面上，供用户查看和处理。
+4. **告警消息推送**：在告警事件发生后，根据配置的通知策略（如电话、短信等），将告警通知发送给相应的接收人。
+
+## 告警事件列表
+
+在告警事件列表中，您可以查看当前实例下所有触发监控规则的告警信息。针对列表中的告警事件，您可以执行以下操作：
+
+- **抑制**：设置当前告警事件在指定时间内不再发送消息。
+- **关闭**：关闭当前告警事件，停止接收此类消息。
+
+![](https://tq2pllvokz.feishu.cn/space/api/box/stream/download/asynccode/?code=MWNiN2NjNWRlMWRkNDE3YjE3ZDhiMzg5NDJmMjlkYmFfVlVZd0dCQXFCeGFtaUVjSFY5U0NEeDlvN3RJS1ozNVdfVG9rZW46SjFVdmIyY2dEb2pWbXR4cFcwTGNMVlNMblFlXzE2ODk1NjM4OTk6MTY4OTU2NzQ5OV9WNA)
+
+### 告警消息列表
+
+告警消息列表展示了实际触发的通知策略产生的所有消息通知。这些通知是通过告警事件触发的。

+| 复制       | 基于当前规则，复制其配置属性，以产生新的规则   | 实例管理员、实例运维角色 |
+| 编辑       | 通过合适的交互方式，支持用户修改监控规则的属性 | 实例管理员、实例运维角色 |
+| 订阅/取消订阅  | 把操作者自身加入/移出告警接收人         | 对实例成员全部开放    |
+
+#### 系统内置规则
+
+产品提供了一些全局的内置监控规则，您可以根据需要启用它们。
+
+| **规则名称**   | **规则作用**                       | **默认启停状态** |

+# 阿里云私有存储配置
+
+本指南将帮助您在阿里云对象存储服务（OSS）上配置BYOS（私有存储），使ClickZetta Lakehouse能够使用您的OSS存储桶作为数据存储位置。
+
+## 前提条件
+
+* 拥有阿里云账号并开通OSS服务
+* 了解您的ClickZetta Lakehouse实例所在的云平台和地域（Region）
+* 拥有OSS存储桶的管理权限
+
+## 步骤一：准备OSS存储桶
+
+### 创建新存储桶（推荐）
+
+如果您选择创建新的存储桶专用于ClickZetta Lakehouse：
+
+1. **登录阿里云OSS控制台**
+
+   访问：<https://oss.console.aliyun.com>
+
+2. **点击“创建Bucket”**
+
+:-: ![](/.topwrite/assets/image_1760269133038.png =712)
+
+**配置Bucket基本信息**
+
+| 配置项          | 设置值                           | 说明                                                                |
+| ------------ | ----------------------------- | ----------------------------------------------------------------- |
+| **Bucket 名称** | 自定义（如：`my-company-lakehouse`） | 全局唯一，建议包含用途标识                                                     |
+| **地域**       | 与 Lakehouse 实例相同                | ⚠️ **关键要求**：必须选择与 ClickZetta Lakehouse 实例相同的地域                      |
+| **存储类型**     | 标准存储                          | 避免使用低频或归档存储，频繁读取会产生超额取回费用。                                         |
+| **存储冗余类型**   | 本地冗余存储（LRS）                   | 可根据需求选择同城冗余存储（ZRS）。                                                 |
+| **读写权限**     | 私有                            | 确保数据安全。                                                           |
+| **服务端加密**    | 无                             | Lakehouse 会自行管理加密，全局加密可能影响性能。                                      |
+| **版本控制**     | 关闭                            | 避免产生额外费用。                                                          |
+| **定时备份**     | 关闭                            | 对象存储内的备份由于缺少元数据，单独备份出的数据不可读。如需备份，可使用 Lakehouse 的 Time Travel 功能进行备份。 |
+
+***
+
+### 使用已有存储桶
+
+如果您选择使用已有的存储桶：
+
+#### 验证地域配置
+
+存储桶必须与 ClickZetta Lakehouse 实例在同一地域（Region）。例如：
+- Lakehouse 实例在：阿里云华东 2（上海）
+- OSS Bucket 必须在：华东 2（上海）
+
+您的服务实例所在“云服务商和地域”信息可在服务实例首页查询到：
+
+:-: ![](/.topwrite/assets/image_1760270239517.png =747)
+
+#### 选择存储路径
+
+您可以选择以下方式之一：
+
+**方式一：使用整个 Bucket（推荐）**
+
+适用场景：Bucket 专用于 Lakehouse
+
+**方式二：使用 Bucket 下的特定目录**
+
+适用场景：需要在同一 Bucket 中隔离不同用途的数据
+
+***
+
+**数据安全警告**：
+
+1.  请确保所选路径不与其他业务系统共用。
+2.  ClickZetta Lakehouse 会对该路径下的文件进行读、写、删除操作。
+3.  共用路径可能导致：
+    *   数据被意外删除或覆盖。
+    *   影响其他业务系统的正常运行。
+    *   数据一致性问题。
+
+建议：为 Lakehouse 创建独立的 Bucket 或使用独立的目录。
+
+### 记录必要信息
+
+请记录以下信息，后续配置时需要使用：
+
+* **Bucket名称**
+* **Bucket所在地域**
+* **存储路径**（如使用子目录）
+* **您的阿里云主账号ID**
+
+查看主账号ID的方法：
+
+1. 登录阿里云控制台
+2. 点击右上角头像
+3. 在"账号信息"中查看"账号ID"
+
+## 步骤二：配置Bucket访问策略
+
+**1. 进入 Bucket 管理页面**
+
+*   在 OSS 控制台找到您的 Bucket
+*   点击 Bucket 名称进入详情页
+
+**2. 进入权限控制页面**
+
+:-: ![](/.topwrite/assets/image_1760270528220.png =752)
+
+* 点击左侧菜单“权限控制” → “Bucket 授权策略”。
+* 点击“添加授权”。
+
+**3. 配置授权策略**
+
+选择“自定义授权”，填写以下信息：
+
+| 配置项      | 设置值                                                                           |
+| -------- | ----------------------------------------------------------------------------- |
+| **授权资源** | `acs:oss:*:*:your-bucket-name/*` 或 `acs:oss:*:*:your-bucket-name/your-path/*` |
+| **授权用户** | 填写 ClickZetta Lakehouse 的主账号 ID：1384322691904283                                 |
+| **授权操作** | 选择“完全控制”。                                                                     |
+| **条件**   | 不设置。                                                                           |
+
+:-: ![](/.topwrite/assets/image_1760270723389.png =588)
+
+^
+
+**为什么需要完全控制权限？**
+
+ClickZetta Lakehouse 需要该路径下的完全控制权限，以确保能正常进行数据的增、删、读、写操作。
+
+^
+
+完成上述配置后，即可在创建私有存储时使用您的私有存储路径和云平台主账号ID。

+# 创建阿里云存储连接
+
+本步骤的目标是：允许 Lakehouse 集群访问阿里云上的对象存储 OSS。为了完成这个目标，可以使用阿里云提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
+
+## 方式1：访问密钥（AK信息）
+
+仅需提供拥有访问 OSS 权限的账号的 AccessKey ID 和 AccessKey Secret 信息，利用这些信息创建存储连接（Storage Connection）对象，示例如下：
+
+```
+CREATE STORAGE CONNECTION IF NOT EXISTS hz_conn_ak
+    TYPE oss
+    ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com'
+    ACCESS_ID = 'LTAI5tMmbq1Ty1xxxxxxxxx'
+    ACCESS_KEY = '0d7Ap1VBuFTzNg7gxxxxxxxxxxxx'
+    COMMENTS = 'OSS public endpoint';
+```
+
+## 方式2：角色授权（RoleARN）
+
+需要创建一个角色和权限策略：权限策略代表 OSS 服务的访问策略，将这个策略授权给创建的角色。
+
+**以下主要讲述角色授权方式（RoleARN）的具体操作步骤：**
+
+### 1. 阿里云侧操作：在阿里云 RAM 控制台中创建权限策略（CzUdfOssAccess）
+
+> 注意：需要用户具备 RAM 权限。
+
+* 访问阿里云访问控制（RAM）控制台。
+* 左侧导航栏 **权限管理** -> **权限策略**，在权限策略界面选择 **创建权限策略**。
+* 在**创建权限策略**页面选择 **脚本编辑** 页签，将下面 `[bucket_name_1|2|3]` 替换为实际的 OSS bucket 名称。注意：按照阿里云 OSS 的约定，同一个 bucket 需要有两条 Resource 条目：`"acs:oss:*:*:bucket_name_1"` 与 `"acs:oss:*:*:bucket_name_1/*"` 同时存在才能达到授权效果。
+
+```JSON
+{
+    "Version": "1",
+    "Statement": [
+        {
+            "Effect": "Allow",
+            "Action": [
+                "oss:GetObject",
+                "oss:ListObjects",

+                "oss:DeleteObject"
+            ],
+            "Resource": [
+                "acs:oss:*:*:bucket_name_1",
+                "acs:oss:*:*:bucket_name_1/*",

+# 修改dynamic table
+
+Lakehouse 系统支持使用 `ALTER` 语句对动态表进行运维管理：
+
+* **暂停和启动调度任务**：控制由 Lakehouse 系统自动刷新的调度任务。
+* **表注释**：更新动态表的描述信息。
+* **列名**：修改现有列的名称。
+
+对于涉及 **SQL 查询逻辑变化** 的修改（即动态表定义中的 `SELECT` 加工过程），必须使用 `CREATE OR REPLACE` 语法。这是因为动态表与普通表不同，其定义包含了数据加工逻辑，而不仅仅是静态结构。以下需要使用CREATE OR REPLACE 语法修改。需要注意的是，如果用户不是简单的删除列/添加列（添加列定义：只能是从表一路经由 SELECT 透传的，不能参与任何会影响其他列的计算，例如 join key、group key 等），则在 CREATE OR REPLACE 发生后，REFRESH 任务会退化为一次全量刷新。
+
+* **调度周期**：调整调度任务的执行频率。
+* **计算集群**：指定用于处理动态表的计算资源。
+* **增加列**：动态表增加列，涉及到SQL语法结构变化。
+* **减列**：动态表减列，涉及到SQL语法结构变化。
+* **修改列类型**：涉及到SQL语法结构变化。
+* **修改动态表中SQL语法定义**：涉及到SQL语法结构变化。
+

+# 修改分享对象（SHARE）
+
+## 功能描述
+
+该语句用于修改分享对象（SHARE）。您可以使用此语句为分享对象添加或移除目标服务实例（INSTANCE）。
+
+## 语法
+
+```SQL
+ALTER SHARE <share_name> [ADD | REMOVE] INSTANCE <instance_name>;
+```
+
+## 参数说明
+
+1. **share_name**：需要修改的分享对象名称。
+2. **ADD | REMOVE**：对分享对象的操作，ADD 表示添加分享目标服务实例，REMOVE 表示移除已分享的服务实例。
+3. **instance_name**：服务实例的名称，需确保全局唯一。服务消费端用户可以在首页右侧或在服务实例的 URL 中找到自己的服务实例名称，并提供给分享者进行配置。
+
+## 使用示例
+
+**添加分享目标服务实例**
+
+假设您创建了一个名称为`SHARE_DEMO`的分享对象，其 `kind` 属性为 ‘OUTBOUND’，想要将其分享给名为`instancedemo`的服务实例，可以使用以下语句：
+
+```SQL
+ALTER SHARE SHARE_DEMO ADD INSTANCE instancedemo;
+```
+
+**移除分享目标服务实例**
+
+如果您创建了一个名称为`SHARE_DEMO`的分享对象，并且已分享给名为 `instancedemo` 的服务实例，想要收回对该服务实例的分享，可以使用以下语句：
+
+```SQL
+ALTER SHARE SHARE_DEMO REMOVE INSTANCE instancedemo;
+```
+
+## 注意事项
+
+* 确保在执行此操作时，已登录到具有相应权限的账户。
+* 在添加或移除分享目标服务实例时，请确保输入的实例名称正确无误。
+* 对 SHARE 对象执行 REMOVE INSTANCE 后，目标服务实例会立即失去使用该分享数据的权限。请谨慎操作，确认操作影响。
+
+通过以上步骤，您可以轻松地管理分享对象及其关联的服务实例。

+
+## 语法
+```
+ALTER USER user_name SET
+[DEFAULT_VCLUSTER= vc_name] 
+[DEFAULT_SCHEMA=schema_name]
+```
+**1. DEFAULT_VCLUSTER**: 为用户指定默认的计算资源。如果未指定，则使用全局默认计算资源。
+
+**2. DEFAULT_SCHEMA**: 为用户指定默认的模式（schema）。如果用户未指定默认模式，登录时需要指定要访问的模式，否则会报错。如果指定了默认模式，用户登录时将默认使用该模式。在会话中使用 `USE` 命令可以切换到其他模式。优先级：`USE` 命令 > 默认模式。

+# 修改工作空间属性
+
+在本节中，我们将介绍如何修改工作空间的属性，包括修改工作空间的注释（comment）等。这将帮助您更好地管理和组织您的工作空间。
+
+## 修改工作空间的注释
+
+要修改工作空间的注释，您可以使用以下SQL语句：
+
+```
+ALTER WORKSPACE wbname SET COMMENT 'comment';
+```
+
+在这里，`wbname`代表您要修改的工作空间名称，而`comment`则是您想要设置的新注释。
+
+## 修改Workspace的PROPERTIES
+
+```SQL
+ALTER WORKSPACE wbname SET PROPERTIES ('key'='value')
+```
+
+要查看 Workspace PROPERTIES，请使用以下语法：
+
+```SQL
+SHOW PROPERTIES IN WORKSPACE <workspace_name>
+```
+
+## 案例
+
+**示例：修改工作空间的注释**
+
+假设您有一个名为`ql_ws`的工作空间，您想要为其添加一条注释：“这是一个用于查询的工作环境。”您可以使用以下SQL语句进行修改：
+
+```
+ALTER WORKSPACE ql_ws SET COMMENT '这是一个用于查询的工作环境。';
+```
+
+执行该语句后，您可以使用 `DESC` 命令查看工作空间的详细信息，确认注释已成功修改：
+
+```
+DESC WORKSPACE ql_ws;
+```
+
+查询结果将显示类似以下内容：
+
+```
++--------------------+-----------------------------------------+
+|     info_name      |               info_value                |

+| name               |                ql_ws                    |
+| creator            |               UAT_TEST                   |

+# 合理规划和使用Virtual Cluster
+
+本章节将介绍ClickZetta Lakehouse弹性计算资源的产品特性及规划使用的方法。
+
+## Virtual Cluster特性介绍
+
+计算集群（Virtual Cluster，简称：VC）是ClickZetta Lakehouse提供的计算资源集群服务。计算集群提供在Lakehouse中执行查询分析所需的CPU、内存、本地临时存储（SSD介质）等资源。这三种资源被捆绑到称为Lakehouse计算单元的计算规模单元中。 CRU 作为计算资源大小和性能的抽象、规范化的度量单位。
+
+![](.topwrite/assets/image_1718616076626.png)
+
+ClickZetta Lakehouse根据不同规格计算资源的实际使用时长（秒粒度计算时长）进行计量，不同规格的CUR以及计量单价如下：
+
+| **Lakehouse Virtual Cluster规格** | **CRU**\*时 | **MAX\_CONCURRENCY默认值** |
+| ------------------------------- | ---------- | ----------------------- |
+| 1                               | 1          | 8                       |
+| 2                               | 2          | 8                       |
+| 4                               | 4          | 8                       |
+| 8                               | 8          | 8                       |
+| 16                              | 16         | 8                       |
+| 32                              | 32         | 8                       |
+| 64                              | 64         | 8                       |
+| 128                             | 128        | 8                       |
+| 256                             | 256        | 8                       |
+
+> 注：计算集群的vcluster\_size参数同时支持以T-shirt size（XSMALL、SMALL、Large等）和以数字（1,2,4,16等）表达的方式，以提供更丰富的计算集群规格，满足不同场景的需要。更多信息详见：[计算集群规格代码变更说明](vcluster_size_description.md)
+
+^
+
+ClickZetta Lakehouse支持纵向和横向2个维度的计算资源弹性伸缩：
+
+* 纵向：通过修改Virtual Cluster的规格大小调整CRU数量，提升或降低指定集群的算力和性能
+* 横向：通过修改集群的Replica数量，扩大或减少Cluster副本数调整并发查询能力。
+
+## 根据负载规划计算资源数量和大小
+
+### 计算资源使用最佳实践原则
+
+* 通过多计算资源实现负载隔离
+
+  * 使用多个独立的Virtual Cluster支撑不同业务（Workload）。可根据周期性ETL、线上业务报表、分析师数据分析等不同需求，创建不同的计算资源并分配给不同的用户或应用使用，避免不同业务或人员资源争抢导致的SLA下降。
+
+* 合理设置自动暂停时长
+
+  * Lakehouse的计算资源具备IDLE闲置时自动暂停、作业发起时自动拉起、按实际资源使用时长计费（暂停阶段不计费）的特性，通过AUTO\_SUSPEND\_IN\_SECOND参数可以设置，默认为600秒无查询时自动暂停。
+
+  * 不同场景的建议（考虑数据Cache和资源Resume时间2个维度）
+
+    * 低频使用Ad-hoc查询或ETL作业，AUTO\_SUSPEND\_IN\_SECOND为1Min左右。
+    * 高频分析场景，AUTO\_SUSPEND\_IN\_SECOND=10Min以上，保持分析依赖的数据始终在Cache当中，同时避免频繁VC启停带来的Latency下降。
+
+* 根据负载类型选择Virtual Cluster的资源类型
+
+  * **通用型集群（VCLUSTER\_TYPE=GENERAL**） 可对于分析场景的并发和作业时效性保障要求不强情况下，可以完成分析引擎所做的所有事情。为批处理Workload优化，吞吐优先、支持资源争抢&共享，适用于ELT、数据导入（如外表读取及写入）、Ad-hoc查询等场景。
+  * **分析型集群（VCLUSTER\_TYPE=ANALYTICS**） 支持指定作业并发数的分析引擎。适用于对查询Latency和并发能力有强保障的场景，如Reporting、Dashboard、关键业务的数据产品。
+  * **同步型集群**（**VCLUSTER\_TYPE**=**INTEGRATION**）适用于处理离线集成和实时集成任务。多个集成任务可共用一个同步型计算集群实例。超出集群计算能力的集成任务将进入队列排队。
+
+* 使用弹性并发能力支持关键数据应用
+
+  * 分析型Virtual Cluster支持多Replica副本特性，Replica默认为1，可以在创建时或创建后修改。每个Replica支撑特定的并询并发（由MAX\_CONCURRENCY参数决定，默认为8），每个Virtual Cluster能够支持的并发数量为：Replica Number \* MAX\_CONCURRENCY
+  * \:-:
+    ![](.topwrite/assets/image_1741750995792.png =645)
+  * 并发设置：在确定Virtual Cluster规格大小的情况，提高并发度会可能降低单个Query的查询性能；大多数情况下，并发度上限建议不超过100；并发度的取值建议使用8的整数倍。示例如下：
+
+    ```SQL
+    --创建分析型VC，开启弹性并发(min_replicas=1 max_replicas=3 )
+    create vcluster if not exists your_ap_vc vcluster_size='XSMALL' vcluster_type='Analytics'  AUTO_RESUME=TRUE AUTO_SUSPEND_IN_SECOND=300 min_replicas=1 max_replicas=3 ;
+    —修改replicas参数，提高横向伸缩的Replica数量以增加弹性并发
+    alter vcluster your_ap_vc set max_replicas=6;
+    --修改单个replica的并发大小，适合计算逻辑简单和数据规模较小的固定报表场景
+    alter vcluster your_ap_vc set MAX_CONCURRENCY=32 ;
+    --修改Virtual Cluster的规格大小，影响所有弹性并发创建的replica的规格并发大，以提升单个查询的查询性能
+    alter vcluster your_ap_vc set vcluster_type='MEDIUM';
+
+    3. 查询和配置MAX_CONCURRENCY
+    - 查询MAX_CONCURRENCY
+    使用以下语句，可以查询指定VC的配置参数，可在其中找到该VC集群当前的MAX_CONCURRENCY配置值：
+    DESC VCluster <name>
+    - 配置MAX_CONCURRENCY
+    使用以下语句，可以配置指定VC的MAX_CONCURRENCY。对于分析型的VC集群，MAX_CONCURRENCY的配置适用于其中的所有实例。
+    ALTER VCluster <name> SET MAX_CONCURRENCY = {希望设置的正整数}
+    ```
+
+### Lakehouse Virtual Cluster不同场景的容量设计建议
+
+当前ClickZetta Lakehouse支持的主要业务场景的业务特点如下：
+
+| **场景/工作负载** | **场景需求**                               | **资源需求需求** | **数据规模及查询时延需求**                          | **Query特点**        | **并发特点**              |
+| ----------- | -------------------------------------- | ---------- | ---------------------------------------- | ------------------ | --------------------- |
+| 固定报表        | 多并发，稳定的低时延                             | 小+弹性扩缩     | •小，查询GB规模 •如 TP95 <3秒                    | 针对加工好的数据，逻辑简单、模式固定 | 面向广泛的一线人员，10\~100或更大  |
+| Ad-hc       | 明细数据支持交互式探查、分析                         | 中          | •中，100GB\~10TB •大部分查询期望10秒内，对复杂查询的时延有容忍度 | 逻辑较复杂              | 面向专业分析人员，较少 （与组织规模相关） |
+| ETL         | 按计划稳定产出 成本敏感，控制成本 突发状况下有弹性需求（如补数、临时出数） | 大          | •大，TB\~PB+级别 •小时级，产出完成时间有SLA需求           | 逻辑复杂 加工型：进多出多      | 低，单用户的多任务 接受作业常态化挤压排队 |
+
+### Virtual Cluster资源规格设计参考
+
+本文计划从业务负载类型、执行频率、作业并发、处理数据规模、SLA要求几个维度提供样例的资源规格设计，供参考使用。
+
+* **负载类型**：包括ETL、Ad-hoc、Reporting、实时分析(Operational Analytics等不同特点的数仓工作负载

+| 规格       | 虚拟集群内计算资源实例大小。规格范围从XS\~5XLarge，规格增加一级，算力资源增加一倍。                                                  |
+| 类型       | 通用型或分析型，此处我们使用分析型。                                                                               |
+| 最大并发数    | 单个计算资源实例支持的并发查询，超过单实例最大并发数时，新的查询将排队或分配到虚拟集群内的其他计算资源实例。                                           |
+| 实例最小值    | 虚拟集群初始启动时集群实例数量，默认为1。                                                                            |
+| 实例最大值    | 虚拟集群可以使用的最大实例数量。当实例最大值>实例最小值时，意味着根据虚拟集群接收到的并发数量是否超过所有计算实例的总最大并发数决定是否自动横向扩展新的计算实例，直到当前实例数量=实例最大值。 |
+| 当前实例数量   | 虚拟集群当前使用的实例数量。                                                                                   |

+
+垂直伸缩：其中实例规格是对虚拟集群进行垂直伸缩的选项，调整实例规格可以让单个作业获得更大的算力以提升作业性能。
+
+横向伸缩：以提高集群并发能力为目标的弹性能力。分析型集群面向横向伸缩场景，提供了单集群内多实例的架构设计。每个分析型集群通过设置实例最小值、实例最大值定义集群初始实例数量以及横向扩容的上限。
+
+在实际的业务场景中，对于面向用户的数据产品往往有SLA的要求，如100并发下P99的查询延迟小于2秒。同时，也希望计算资源得到充分的利用，在满足业务需求的前提下尽可能降低资源成本。如下图所示：
+
+![](.topwrite/assets/image_1718616492933.png)
+
+在特定的业务场景下，我们希望能够找到性能满足SLA要求的最小资源需求。本文从实践角度，结合示例场景通过以下几个步骤工作来确定合理的资源规格配置。
+
+### 场景示例
+
+数据平台加工后的数据包装称为数据产品（如Dashboard），对外支撑最大20用户并发查询，其中单个用户每次数据产品请求平均产生8个数据平台查询（平均每个Dashboard 8个指标），相当于对数据平台有160个并发查询。要求P99查询延迟小于1.5秒。
+
+数据查询具备以下特点：
+
+* Dashboard查询使用数据集大小：1GB左右。
+* Dashboard查询的特点：以点查、过滤、聚合为主，无JOIN。
+
+本文使用SSB FLAG 1G的数据集和查询语句来模拟上述场景，用于验证并发查询下的集群配置及效果。
+
+### 第1步：找到性能、成本平衡的单实例规格大小
+
+1. 使用不同SIZE的集群规格运行查询（如本文使用从Large->XSMALL几种规格分别进行了测试），找到资源规格尽可能小、同时性能下降不明显的资源规格。
+
+根据下图所示，SSBF-1G的benchmark在XSMALL规格时仍然保持了Large的80%以上性能表现。这里选择XSMALL规格来支持数据产品。
+
+注：根据测试结果，建议 100G数据规模默认使用 Large大小，10G 使用 Medium，1G 对应 Small或XSmall。
+
+![](.topwrite/assets/image_1718616512495.png)
+
+### 第2步：测试单实例下在多大并发下，有较好的查询SLA、QPS
+
+如下图所示，使用XSMALL规格集群，在8并发请求下，QPS较高、P95/P99查询表现好。
+
+![](.topwrite/assets/image_1718616524873.png)
+
+### 第3步：通过横向扩容，找到同时满足SLA和业务实际并发需求的最大实例数
+
+根据前文介绍，一个集群能够支持的并发数= 实例最大值 \* 实例最大并发数。原则上，单实例规格大小确定后，横向扩展的实例具备同样的查询SLA和QPS。
+
+结合测试数据，本文将使用XSMALL规格，最大实例数=10的虚拟集群，可以满足160并发的查询需要。查询响应时长P95=1111毫秒，P99=1280.65毫秒。

+
+### 小结

+# 功能
+
+ANALYZE TABLE 语句用于收集指定 schema 中特定表或所有表的统计信息。统计信息包括表的大小、行数等，查询优化器利用这些信息生成最佳的查询计划。虽然这些统计信息可能会随着数据的变化而过时，但查询优化器仍然可以利用这些过时的信息生成有效的查询计划。在 Lakehouse 中，通过执行 DESC 命令获取的统计信息可能存在延迟，因此执行 ANALYZE TABLE 语句可以获取最新的统计信息。
+
+# 语法
+
+```SQL
+-- 收集指定表的统计信息
+ANALYZE TABLE table_name
+   COMPUTE STATISTICS [NOSCAN | FOR COLUMNS col1 , col2... | FOR ALL COLUMNS ]
+
+-- 收集指定schema下所有表的统计信息
+ANALYZE TABLES [IN schema_name] COMPUTE STATISTICS [NOSCAN]
+```
+
+# 参数
+
+必选参数：
+
+* `table_name`：要收集统计信息的表名称。支持普通表、动态表、物化视图。
+
+可选参数：
+
+* `NOSCAN`：仅收集表的大小（以字节为单位），不需要扫描整个表。
+* `FOR COLUMNS col1, col2, ...`：收集每个指定列的列统计信息。
+* `FOR ALL COLUMNS`：收集所有列的统计信息。
+* `IN schema_name`：指定目标 schema 的名称。如果不指定，则默认使用当前 schema。
+
+# 注意事项
+
+* 在执行 ANALYZE TABLE 语句时，可能会对表进行扫描，因此可能会影响查询性能。建议在系统负载较低时执行此操作。
+* 在使用 [实时接口](<java_reference/realtime-upload.md>) 追加模式时，ANALYZE TABLE 语句不会统计未提交的数据，因此 `select count(*) from table` 的结果可能偏少。
+
+# 使用示例
+
+1. 收集指定表的统计信息（不扫描表），仅收集表的大小（以字节为单位）：
+
+```SQL
+ANALYZE TABLE sales COMPUTE STATISTICS NOSCAN;
+```
+
+2. 收集指定表的列统计信息：
+
+```SQL
+ANALYZE TABLE customers COMPUTE STATISTICS FOR COLUMNS customer_id, customer_name;
+```
+
+3. 收集指定schema下所有表的统计信息：
+
+```SQL
+ANALYZE TABLES IN sales_schema COMPUTE STATISTICS;
+```
+
+4. 收集指定表的所有列的统计信息：
+
+```SQL
+ANALYZE TABLE orders COMPUTE STATISTICS FOR ALL COLUMNS;
+```

+### 推荐原因
+
+推荐的列可以用作表的 sort key。
+
+挑选的是经常出现在过滤语句中的列。如果将这些列设置为表的 sort key，可以加快 query 的执行速度。
+
+### 如何启用
+
+* 可以在 workspace 上设置 property，系统会分析 workspace 下所有的表。
+
+```Plain
+ALTER WORKSPACE workspace_name SET properties (auto_index='day[,150,5,100]');
+
+比如：
+ALTER WORKSPACE quick_start SET properties (auto_index='day'); 
+ALTER WORKSPACE quick_start SET properties (auto_index='day,150,5,100');
+
+第一个参数为必须设置，即指定是每天收集还是每月收集，每月收集为每月1号收集，收集时间为晚上6点
+第二个参数为使用最近多长时间的job（单位是分钟），默认为150
+第三个参数为job需要重复多少次才会被使用，默认为5
+第四个参数为每个列使用的最多的job数，默认为100
+```
+
+* 自动收集
+
+系统会自动收集每个 schema 中过滤语句使用最多的 10 张表。
+
+### 如何查询
+
+```Plain
+Select * from information_schema.sortkey_candidates;
+
+返回结果比如:
+instance_id,workspace_id,workspace_name,schema_id,schema_name,table_id,table_name,col,statement,ratio,insert_time,p_date
+11111111111,855911111111,aaaaaaaaaaa,23671111111111,ddddddddd,84465111,aaaaaaaaaaa.ddddddddd.member,brandid,alter table aaaaaaaaaaa.ddddddddd.member set properties("hint.sort.columns"="brandid"), 2.21%,05:49.1,2024/11/7
+11111111111,855911111111,aaaaaaaaaaa,23671111111111,ddddddddd,84465111,aaaaaaaaaa.ddddddddd.member,birthday,alter table aaaaaaaaaa.ddddddddd.member set properties("hint.sort.columns"="birthday"),0.01%,05:49.1,2024/11/7
+11111111111,855911111111,aaaaaaaaaaa,23671111111111,ddddddddd,84465111,aaaaaaaaaaa.ddddddddd.member,id,alter table aaaaaaaaaaa.ddddddddd.member set properties("hint.sort.columns"="id"),0.01%,05:49.1,2024/11/7
+
+可以看到对于aaaaaaaaaaa.ddddddddd.member表来说brandid的提升效果最高，所以设置为sortkey alter table aaaaaaaaaaa.ddddddddd.member set properties("hint.sort.columns"="brandid"),此设置会对
+
+```
+
+包含的列为：`instance_id`、`workspace_id`、`workspace_name`、`schema_id`、`schema_name`、`table_id`、`table_name`、`col`、`statement`、`ratio`、`insert_time`、`p_date`。
+
+其中 `p_date` 为分区列，其格式是 `yyyy-mm-dd`。
+
+`insert_time` 是收集结果插入的时间。
+
+`col` 是推荐的列，当前为单列。
+
+`statement` 是用于将推荐列设置为排序列的 SQL 语句。
+
+`ratio` 为估算的提升效果，为百分比。
+
+### 使用建议
+
+建议使用 [analyze语句](<analyze-table.md>) 对表收集一下 column 的 stats，这会提高推荐的准确性。

+# 创建亚马逊云存储连接
+
+本步骤的目标是：允许 Lakehouse 集群访问亚马逊云(AWS)的对象存储 S3。为了完成这个目标，可以通过AWS 的**身份与访问管理(IAM**) 产品提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
+
+## 基于访问密钥
+
+```
+CREATE STORAGE CONNECTION aws_bj_conn
+    TYPE S3
+    ACCESS_KEY_ID = 'AKIAQNBSBP6EIJE33***'
+    SECRET_ACCESS_KEY = '7kfheDrmq***************************'
+    ENDPOINT = 's3.cn-north-1.amazonaws.com.cn'
+    REGION = 'cn-north-1';
+```
+
+### 参数：
+
+* TYPE：为对象存储类型，AWS 应填写 S3（大小写不限）
+* ACCESS\_KEY\_ID / SECRET\_ACCESS\_KEY：为AWS 的访问密钥，获取方式参考：[访问密钥](https://docs.aws.amazon.com/zh_cn/IAM/latest/UserGuide/id_credentials_access-keys.html)
+* ENDPOINT:  S3 的服务地址，AWS 中国区分为北京区和宁夏区，北京区的S3 的服务地址为 `s3.cn-north-1.amazonaws.com.cn`， 宁夏区 `s3.cn-northwest-1.amazonaws.com.cn`，可参考：[中国区终端节点](https://docs.amazonaws.cn/aws/latest/userguide/endpoints-arns.html) 分别找到北京区域和宁夏区域的终端节点 -> Amazon S3 对应的终端节点
+* REGION：AWS 中国区分为北京区和宁夏区，区域值为：北京区 `cn-north-1`， 宁夏区 `cn-northwest-1`，可参考：[中国区终端节点](https://docs.amazonaws.cn/aws/latest/userguide/endpoints-arns.html)。国际站请参考：[Amazon Simple Storage Service endpoints and quotas](https://docs.aws.amazon.com/general/latest/gr/s3.html)
+
+## 基于角色授权
+
+需要在目标云对象存储 S3 所属的账号，在 IAM 中创建一个**权限策略**和**角色**：权限策略代表访问AWS S3 数据的规则，将这个策略授权给创建的角色。云器 Lakehouse 通过扮演这个角色来实现与 S3 中数据的读写操作。
+
+### STEP1: AWS侧创建权限策略 (LakehouseAccess )：
+
+* 登录AWS 云平台，进入**身份与访问管理(IAM**) 产品控制台
+* 在 IAM 页面左侧导航栏进入 **账户设置**，在 **Security Token Service (STS**) 中的 **终端节点** 列表中，找到当前实例对应云器Lakehouse 的区域，如果 **STS  状态** 的状态为未开启请开启。
+* 在 IAM 页面左侧导航栏进入 **策略**，在 **策略** 界面选择 **创建策略**，在策略编辑器中选择 JSON 方式
+* 将要添加允许云器Lakehouse 访问 S3 bucket 和目录的策略。下面是策略的样例，请用实际的bucket 和路径前缀名称替换 `<bucket>` 和 `<perfix>` 名称
+
+> 注意：请将 `"s3:prefix" `项中填写:  `["*"]` or `["<path>/*"]` 分别代表授予对指定 bucket 或 bucket 中路径中的所有前缀的访问权限。
+
+```
+{
+    "Version": "2012-10-17",
+    "Statement": [
+        {
+            "Effect": "Allow",
+            "Action": [
+              "s3:PutObject",
+              "s3:GetObject",
+              "s3:GetObjectVersion",
+              "s3:DeleteObject",
+              "s3:DeleteObjectVersion"
+            ],
+            "Resource": "arn:aws:s3:::<bucket>/<prefix>/*"

+            "Condition": {
+                "StringLike": {
+                    "s3:prefix": [
+                        "<prefix>/*"
+                    ]
+                }
+            }
+        }
+    ]
+}
+```
+
+* 选择  下一步，输入策略名称如,(LakehouseAccess）和描述（选填）
+* 点击创建策略完成策略创建
+
+### STEP2: AWS侧创建角色 (LakehouseVolumeRole)：
+
+* 登录AWS 云平台，进入**身份与访问管理(IAM**) 产品控制台
+* 在 IAM 页面左侧导航栏进入**角色** -> **创建角色** -> **AWS账户**，选择 **另一个AWS账户**，在 Account ID 输入 `028022243208（中国站） / 014617434350（国际站）`
+
+> 注意：为了防止 ROLE\_ARN 被第三方获取进行未授权的数据访问，可以勾选 **选项** 中的 **需要外部ID(第三方担任此角色时的最佳实践**)，勾选之后 **EXTENRAL ID** 项可以填写 `000000` 占位符稍后填充。`EXTERNAL ID` 作为一种额外的验证层，确保只有当请求中包含了预设的 `EXTERNAL ID` 时，这一访问才会被允许。这意味着即使第三方知道了其他一些访问信息（如角色ARN），没有正确的 `EXTERNAL ID` 也无法访问资源。
+
+![](.topwrite/assets/image_1728551322654.png)
+
+* 选择下一步，在添加权限（Add permissions）页面，选择STEP1 中创建的策略 `LakehouseAccess `**后**，选择下一步
+* 填写 Role name (例：`LakehouseVolumeRole` ) 和描述，点击 **创建角色** 完成角色创建
+* 在角色详情页中，获取 **Role ARN** 的值，用来创建 STORAGE CONNECTION
+
+![](.topwrite/assets/image_1728551348143.png)
+
+^
+
+### STEP2: 云器 Lakehouse 侧创建 STORAGE CONNECTION ：
+
+* 在 Studio 或者 Lakehouse JDBC 客户端中执行以下命令：
+
+```
+CREATE STORAGE CONNECTION aws_bj_conn_arn
+  TYPE S3
+  REGION = 'cn-north-1'
+  ROLE_ARN = 'arn:aws-cn:iam::02802*******:role/LakehouseVolumeRole';
+```
+
+* 在创建存储连接的过程中，Lakehouse 会生成此EXTERNAL ID，可以将此EXTERNAL ID 配置到 STEP2创建的 AWS IAM 角色（`LakehouseVolumeRole`）的 Trust Policy 中，实现附加的访问控制：
+
+```
+-- 查看 EXTERNAL ID 
+DESC CONNECITON my_tx_connection_arn ;
+```
+
+![](.topwrite/assets/20240626-215920.jpeg)
+
+^
+
+* 在AWS IAM 的控制台，左侧导航栏中进入角色 **Roles**，找到 STEP2 中创建的角色并进入角色详情页面，在 **Trust relationships** 中将 `sts:ExternalId `的值`  000000  `替换为 DESC 结果中的` EXTERNAL_ID`。点击**更新** 完成角色策略更新。

+# 补数任务
+
+补数据功能可通过补充历史或未来一段时间的数据，将数据写入对应时间分区。若代码中配置了调度参数，系统将根据补数据选择的业务时间自动替换为具体值，并结合业务代码将对应时间的数据写入指定分区。具体写入的分区与执行的代码逻辑由任务定义中的代码决定。
+
+## **功能使用场景**
+
+* 当任务新建后，若希望对历史数据进行加工，可通过补数据功能选择历史某个时间段来执行任务；
+* 当任务在某个时间段内数据有问题或者任务本身异常时，可通过补数据功能对历史异常的数据或任务重新生成实例并执行，以达到修复历史数据的目的。
+
+## 功能操作
+
+### 步骤一：新建补数据任务
+
+1. 点击左侧导航**运维监控 -> 任务运维**，选中**周期任务** Tab，并选择其中任意一个已管理的周期任务，点击操作栏中的“补数据”，进入补数据操作界面。
+2. 配置补数任务的相应参数
+
+* 任务名称：系统默认名称，暂不支持用户修改
+
+* 选择补数任务包含的任务节点
+
+  * 包含当前节点：用户可根据实际需求选择是否勾选当前任务参与补数。
+  * 包含下游节点：用户可根据实际需求勾选需要补数据的**下游任务链路**，支持不选择、选择全部、自定义选择范围三种模式。
+
+* 任务定时时间范围：在创建补数据任务时，支持添加多段计划执行时间范围，用于满足补充多段不连续时间的需求。目前最多支持添加4段计划执行时间，且不允许选择重叠的时间段。
+
+* 最大并发数：表示当连续补充多个周期的数据时，若同时运行的实例数达到此并发上限，则可以并行运行多个周期的实例，从而提升补数据的效率，但也会消耗更多的资源。
+
+  * 最大并发数量，指的是同时运行的最大实例个数。
+
+* 补数自依赖：若用户需要补数任务严格按照业务时间依次往后执行，可选择补数自依赖选项。
+
+  * 若用户同时配置了最大并发数和补数自依赖，则整体执行效率可能会下降。
+
+^
+
+最大并发数与补数自依赖对执行效率的影响：
+
+* 配置最大并发数时，若该周期任务本身没有配置自依赖，同时也没有勾选补数自依赖选项，系统会基于用户配置的并发数，按照系统资源、依赖关系等随机分配执行的具体实例。
+* 若周期任务本身配置了自依赖，或勾选了补数自依赖选项，则同时并发的实例数会受到实例自身顺序依赖逻辑的影响，再结合系统资源、依赖关系等随机分配执行的具体实例，效率会降低。
+
+### 步骤二：查看补数据任务
+
+1. 点击左侧导航**运维监控 -> 任务运维**，选中**补数任务** Tab。
+2. 基础信息：包括并发分组、目标任务ID、任务名称、工作空间、是否包含下游、状态、执行顺序、任务定时时间范围、提交时间、提交人等。
+3. 统计图：
+
+* 全局统计信息：可查看当前补数任务内包含的所有计划时间点总数，并按天粒度展示执行状态。
+
+* 按粒度统计图：提供年、月、日三种粒度下的数据统计，点击统计图会联动下方的实例列表。
+
+  * **年视图**：鼠标悬停在日期上方可查看当天的执行情况；
+    ![](.topwrite/assets/image_1723185910796.png)
+  * **月视图**：可在月视图上查看当天要执行的实例总数，鼠标悬停在日历上方可查看执行状态汇总；
+    ![](.topwrite/assets/image_1723185934736.png)
+  * 日视图：支持按天或按小时两种粒度切换，可查看不同聚合粒度下实例的平均耗时时长。
+    ![](.topwrite/assets/image_1723185952493.png)
+
+4. 实例统计列表：默认按照计划时间展示当前补数任务下所有执行实例的信息，点击可跳转到实例执行的详情页面查看依赖关系等详细信息。

+# 离线同步任务
+
+云器 Lakehouse 工作空间的“开发”模块集成了数据同步任务的定义和调度能力。借助数据开发模块的数据同步任务编辑器，可以快速创建数据同步任务。以下对离线同步任务的创建和使用进行说明。
+
+## 新建数据同步任务
+
+您可分别从工作区和开发入口新建同步任务。
+
+* 由工作区新建
+  通过控制台“工作区”入口，在右侧“新建”按钮下选择新建离线同步或实时同步任务。
+
+  ![](.topwrite/assets/image_1690124841165.png =640)
+
+* 由开发入口新建
+  您可进入“开发”页面，在任务区域选择在指定目录下新建同步任务。
+
+  ![](.topwrite/assets/image_1690125196037.png =320)
+
+## 离线同步任务开发
+
+**第一步：新建离线数据同步任务**
+在指定任务保存位置创建指定名称的离线同步任务。
+![](.topwrite/assets/image_1690125712118.png =320)
+系统将生成同步任务，同时在右侧区域打开数据同步任务编辑器供用户编辑。
+![](.topwrite/assets/image_1690125934293.png =640)
+
+**第二步：定义同步任务**
+
+* 选择源和目标数据源及对应数据对象
+  在数据来源侧，选择现有数据源或新建数据源作为数据来源，并指定需要同步的数据对象。在数据目标侧，选择已有数据源或新建数据源作为目标数据源，目标数据的写入对象支持指定已有数据对象，或根据来源对象快速创建。
+  ![](.topwrite/assets/image_1690126242203.png =640)
+  确定来源对象和目标对象后，数据同步任务将生成来源对象与目标对象的字段映射，默认采用同名映射规则，可通过拖动方式调整字段间的映射关系。支持添加常量字段作为源表字段进行映射和写入。
+
+* 设置数据同步任务的容错和并发规则
+  * 任务并发数：可最小设置为1，最大设置为10。
+  * 任务同步速率：可最小设置为1 MB/s，最大不限制。
+    ![](.topwrite/assets/image_1690126859515.png =460)
+

+## 任务计费
+
+### 问题：数据同步任务如何收费？
+
+回答:数据同步任务的费用，整体分为硬件资源使用费用、数据传输网络费用两大类构成。
+
+* 硬件资源使用费用依据同步型计算集群的规格和使用时长进行按量计费，集群未使用或被停止后，不再收取费用。
+* 数据传输网络费用按实际情况收取：当使用数据集成等功能，批量从Lakehouse通过公网下载、导出数据时，会产生Internet网络传输费用。Internet网络传输以实际产生的传输数据量进行计量并计算费用。从其他数据源通过Internet网络向Lakehouse上传数据所产生的网络传输流量，不收取网络传输费用。若使用专线、Private Link或其他网络产品实现跨云厂商、跨地域或跨VPC网络打通，网络打通本身会产生费用。这部分费用根据网络打通方式的不同，在云器Lakehouse侧产生的由云器收取，在云平台账号中产生的费用由云平台直接收取。
+* 详见：[计费说明](pricing.md)
+
+## 数据源
+
+### 问题：离线同步当前支持的数据源有哪些？
+
+回答:在任务配置页面，进行源端和目标端选择时，会完整列出已支持的数据源类型。若没有可用的数据源，请点击「+」号按钮先前往新建，之后再使用。离线同步的数据源之间可以两两自由组合，来构建丰富的同步链路。详见：[数据源管理](config-datasource.md)
+
+^
+
+### 问题：离线同步如何验证数据源的可访问？
+
+回答:数据源列表中的「测试连通」功能（数据源配置页面也提供该功能），可用于测试数据同步任务环境与数据源之间的访问连通状况。若测试结果显示连通失败，则需检查配置的准确性（如连接串地址、用户名和密码等）以及网络状况。若存在网络不通的问题，可查阅下文的网络连通性章节，其中给出了相应的解决方案。
+
+^
+
+## 网络联通
+
+### 问题：如果数据源端在VPC环境下，如何打通数据同步的网络连通性？
+
+回答:如果数据源在VPC环境下，默认情况下数据同步任务所在的网络环境是无法访问联通的。可以通过以下几种方式来打通：
+
+* 在源端启用允许公网访问、在数据源中配置公网访问的地址。
+* 使用SSH Tunnel：[数据源管理](config-datasource.md)&#x20;
+* 使用Private Link：
+* Private Link和SSH相结合：[通过Private Link和SSH结合来同步VPC内的RDS数据](StudioDI_PrivateLinkVPC_fromRDS.md)
+
+### 问题：如果源端数据库有白名单限制，如何才能确保数据同步任务可连通该数据源？
+
+回答:需将数据同步服务出口IP地址添加至源端的白名单中，不同服务地域的IP地址存在差异，具体地址和配置方式详见：[数据源IP白名单配置指南](datasource_ip_whitelist.md)
+
+## 任务配置
+
+### 问题：离线同步任务配置的主要流程是怎样的？
+
+回答:主要分为数据源创建、来源和目标选择、配置字段映射、并发和脏数据管理等同步规则配置（可选）这几个步骤。配置完成后可手动触发运行测试，随后提交周期定时调度。详见：[离线同步](batch_sync.md)
+
+^
+
+### 问题：如果要控制数据同步时对源端的压力，需要如何配置？
+
+回答:在离线同步任务「同步规则配置」区域，可以通过最大并发数和同步速率两个配置项来分别控制对源端的连接数和读取访问的压力。并发数和同步速率越大、对源端的压力越大。
+
+^
+
+### 问题：如果源端数据中存在“脏数据”的情况，需要如何处理？
+
+回答:在离线同步任务「同步规则配置」区域，可以通过「任务遇脏数据自动结束」和「收集脏数据」两个配置项来控制同步任务对脏数据的处理行为。这些「脏数据」不会被写入到目标端。「脏数据」主要指无法正常写入到目标端的数据，最常见的情况是字段类型不匹配，比如把String类型的字段取值写入到目标INT字段中。
+
+* 「任务遇脏数据自动结束」配置成「是」，那么，在脏数据达到对应的条数时任务会失败退出。
+* 「任务遇脏数据自动结束」配置成「否」，那么，即使有脏数据，任务也会继续执行，不会自动退出。
+* 「收集脏数据」选项会控制是否把脏数据收集起来，在任务运行完成后进行查看。脏数据最多收集1000行数据，最长保存7天。
+
+^
+
+## 报错排查
+
+### 问题：任务运行报错 `java.lang.OutOfMemoryError: Java heap space`如何解决？
+
+原因：通常由于读取的数据中存在较大的字段或行，或者对于支持批量读取数据的数据源，单个批次内同步的数据量较大，超过了同步任务的计算进程的堆内内存。
+
+解决：可通过调整同步任务计算集成内存解决，在任务开发-高级参数中添加参数`taskmanager.memory.process.size`，有效单位m、g，默认1600m
+
+^
+
+### 问题：任务运行报错 `java.lang.OutOfMemoryError: Direct buffer memory`如何解决？
+
+原因：同步任务计算集成的堆外内存不足，通常可能是以下原因：
+
+* 来源数据中中存在较大的字段或行，或者对于支持批量读取数据的数据源，单个批次内同步的数据量较大，且来源数据源会使用堆外内存作为数据缓存，如elasticsearch
+* 目标数据源使用堆外内存攒批发送数据，如Lakehouse，由于一批数据中存在较大行导致某个批次数据超过攒批缓存大小
+
+解决：通常有以下解决方案：
+
+* 参照堆内存超限解决方案，调整`taskmanager.memory.process.size`参数
+* 单独调整任务堆外内存的大小，调整`taskmanager.memory.task.off-heap.size `参数，如256m，或512m
+* 如果数据源支持设置batch size，可适当调小配置值，**但注意，这可能会导致同步效率降低**
+
+### 问题：任务运行报错 `CZLH-67000:Out of Memory undefined: could not allocate block of size 262KB (1.0GB/1.0GB used)`，如何解决？
+
+原因: 底层存储索引数据时默认最大是1G, 如果表数据过多的情况下, 会出现pk数据操作了限制范围
+
+解决:
+
+* 如果是单表离线同步的话, 建议重新建表, 并且在建表时加上`cz.storage.art.max.memory.size.bytes`参数, 具体设置多大, 建议根据表实际大小来按需设置。
+* 如果是多表实时的全量同步报错的话，需要在任务的高级参数中加入`lh.table.cz.storage.art.max.memory.size.bytes`，重新提交任务并启动。
+
+### 问题：任务运行报错 `entity content is too long [320177567] for the configured buffer limit [104857600]`，如何解决？
+
+原因：es 读取数据是通过http 请求批量读取的。es http buffer 有大小限制，默认值是100MB，如果批量的数据大小超过这个限制，则会报错；
+
+解决：
+
+* 降低批量读取的batchSize；
+* 添加高级参数，调大http buffer的大小限制：studio.connector.es.buffer_limit；
+
+说明：降低batchSize会略微降低同步效率，调大studio.connector.es.buffer_limit 则会增加任务使用内存；
+
+### 问题：任务运行报错 `The maximum buffer size of 16777216 is insufficient to read the data of a single field. This issue typically arises when a quotation begins but does not conclude within the confines of this buffer's maximum limit.`，如何解决？
+
+原因：数据集成使用的第三方CSV SDK去读取解析CSV数据，SDK会对数据批量读取，对数据大小有限制，buffer大小默认是16MB；
+
+解决：
+
+添加高级参数：studio.connector.csv_reader.max\_buffer\_size；支持带MB/GB的写法，比如：32MB；
+
+说明：该参数目前仅在OSS/S3 生效；
+
+### 问题：任务运行报错 `Field at index 0 in record starting at line 1 exceeds the max field size of 16777216 characters`，如何解决？
+
+原因：数据集成使用的第三方CSV SDK去读取解析CSV数据，SDK对数据单个字段大小有限制，默认是16MB；
+
+解决：

+# 数据导入 Lakehouse 操作实践：通过 COPY 命令批量加载
+
+本指南将帮助您通过脚本方式和云器Lakehouse SQLLine命令行工具，将大量公共URL Parquet文件中的数据（例如New York City Taxi and For-Hire Vehicle Data）导入到云器Lakehouse中。
+
+1. download_raw_data.sh：将 Public URL Parquet 文件下载到本地。本文以NYC Taxi Data为例，包含450多个文件，60GB的数据（Parquet格式）。
+
+2. initialize_database.sh：通过 Lakehouse SQLLine 命令创建云器 Lakehouse 的 schema 和 tables。
+
+3. Import taxi and FHV data：用 R 转换 Parquet 文件到 CSV 文件，通过 Lakehouse SQLLine COPY 命令将本地 CSV 文件里的数据导入到云器 Lakehouse 的表里，支持批量多个文件的导入。
+
+# 操作指南
+
+脚本下载地址：<https://github.com/yunqiqiliang/nyc-taxi-data-clickzetta>
+
+## 1. Install [ClickZetta SQLLine](https://doc.clickzetta.com/zh-CN/connect-with-cli)
+
+## 2. Install [R](https://www.r-project.org/)
+
+From [CRAN](https://cloud.r-project.org/)
+
+Note that R used to be optional for this repo, but is required starting with the 2022 file format change. The scripts use R to convert Parquet files to CSV before loading into Postgres. There are other ways to convert from Parquet to CSV that wouldn't require R, but I found that R's `arrow` package was faster than some of the other CLI tools I tried
+
+## 3. Download raw data
+
+`./download_raw_data.sh`
+
+When done, modify download_raw_data.sh and run again to download data from 202212:
+wget -i setup_files/raw_data_urls_new\.txt -P data/ -w 2
+
+## 4. Initialize database and set up schema
+
+`./initialize_database.sh`
+
+## 5. Import taxi and FHV data
+
+`./import_yellow_taxi_trip_data.sh`
+
+`./import_green_taxi_trip_data.sh`
+
+`./import_fhv_taxi_trip_data.sh`
+
+`./import_fhvhv_trip_data.sh`
+
+Note that the full import process might take several hours or possibly even over a day, depending on computing power.
+
+# Schema
+
+* `trips` table contains all yellow and green taxi trips. Each trip has a `cab_type_id`, which references the `cab_types` table and refers to one of `yellow` or `green`
+* `fhv_trips` table contains all for-hire vehicle trip records, including ride-hailing apps Uber, Lyft, Via, and Juno
+* `fhv_bases` maps `fhv_trips` to base names and "doing business as" labels, which include ride-hailing app names
+* `nyct2010` table contains NYC census tracts plus the Newark Airport. It also maps census tracts to NYC's official neighborhood tabulation areas
+* `taxi_zones` table contains the TLC's official taxi zone boundaries. Starting in July 2016, the TLC no longer provides pickup and dropoff coordinates. Instead, each trip comes with taxi zone pickup and dropoff location IDs
+* `central_park_weather_observations` has summary weather data by date
+

+# Bitmap 类型说明
+
+Bitmap（位图）是云器 Lakehouse 中用于存储和处理集合类型数据的高效数据类型。云器 Lakehouse 中的 Bitmap 是 **64 位的**，使用 Roaring Bitmap 压缩算法进行优化，能够高效地存储和处理大规模的整数集合。
+
+Bitmap 通过位级操作来表示整数集合，提供极高的空间压缩率。相比于直接存储数组，Bitmap 能够显著降低存储成本，同时提供快速的集合操作性能。
+
+### Bitmap 的特点
+
+* **64 位整数支持**：支持存储 0 到 2^64-1 范围内的整数
+* **高效压缩**：使用 Roaring Bitmap 算法，空间占用极小
+* **快速运算**：支持并集、交集、补集等集合操作，性能优异
+* **二进制序列化**：可与 binary 类型相互转换，方便数据交换
+* **灵活查询**：支持集合包含检查、基数计算等操作
+
+## 语法
+
+### 创建包含 Bitmap 列的表
+
+```SQL
+CREATE TABLE table_name (
+    column_name bitmap
+);
+```
+
+**示例**：
+
+```SQL
+CREATE TABLE bitmap_example (
+    user_id bigint,
+    preference_tags bitmap
+);
+```
+
+### 构建 Bitmap 数据
+
+#### 使用 bitmap\_build 函数
+
+从整数数组构建 Bitmap 对象：
+
+```SQL
+bitmap_build(array_expression)
+```
+
+**示例**：
+
+```SQL
+INSERT INTO bitmap_example VALUES
+    (1, bitmap_build(array(1, 3, 5, 7, 9))),
+    (2, bitmap_build(array(2, 4, 6, 8, 10)));
+```
+
+#### 使用 GROUP\_BITMAP\_STATE 函数
+
+根据输入的表达式（expr）构建一个 bitmap 类型的结果，函数通常用于对整数类型的数据进行分组操作，并将每个分组的唯一值转换为一个 bitmap 数组。
+
+```SQL
+GROUP_BITMAP_STATE(expr)
+```
+
+**示例**：
+
+```SQL
+INSERT INTO bitmap_example
+SELECT user_id, group_bitmap_state(v) AS bitmap_array
+FROM VALUES (1, 1), (1, 2), (1, 2), (2, 3) AS v(user_id, v)
+GROUP BY user_id;
+```
+
+## 注意事项
+
+### 功能限制
+
+1. **不支持比较操作**：Bitmap 类型不支持直接的比较操作（<、>、=、!=等）
+2. **不支持排序和分组**：Bitmap 列不能用于 ORDER BY、GROUP BY 或 DISTINCT 操作
+3. **不支持作为键**：Bitmap 不能作为表的 PRIMARY KEY、PARTITION KEY 或 CLUSTER KEY
+4. **查询屏显示**：clickzetta-java 的版本是 >3.0.21
+
+### 数据有效性
+
+1. **有效的整数范围**：bitmap\_build 函数的输入数组必须包含有效的整数值
+2. **Binary 转换**：使用 binary\_to\_bitmap 进行转换时，输入的 binary 数据使用bitmap\_to\_binary转化必须是有效的 Bitmap 序列化格式
+3. **空值处理**：Bitmap 本身可以是 NULL，但数组中的 NULL 值会被忽略
+
+### 性能考虑
+
+1. **适用场景**：Bitmap 最适合存储稀疏的整数集合或大整数集合
+2. **集合运算**：大规模的集合运算应在数据库层完成，而不是在应用层处理
+
+## 常见 Bitmap 函数
+更多Bitmap函数参考[Bitmap文档](<sql_functions/scalar_functions/bitmap_functions/bitmap_to_binary.md>)

+
+## 使用 SDK 方式写入 Bitmap 数据
+
+### Java SDK 示例
+
+使用 ClickZetta Java SDK 中的 BulkloadStream 来批量写入 Bitmap 数据。需要使用 `RoaringBitmap` 构建 Bitmap 对象。
+
+**构建bitmap对象**：
+
+```Java
+import org.roaringbitmap.longlong.Roaring64NavigableMap;
+Roaring64NavigableMap roaring64Bitmap = new Roaring64NavigableMap();
+roaring64Bitmap.add(1);
+roaring64Bitmap.add(3);
+roaring64Bitmap.add(5);
+roaring64Bitmap.add(7);
+row.setValue("preference_tags", roaring64Bitmap);
+```
+
+**Maven 依赖**
+
+在 `pom.xml` 中添加以下依赖要求版本大于3.0.23：
+
+```XML
+<dependency>
+    <groupId>com.clickzetta</groupId>
+    <artifactId>clickzetta-java</artifactId>
+    <version>${version}</version>
+</dependency>
+```
+
+### Python SDK 示例
+
+**Python依赖**：
+
+```python
+pip install clickzetta clickzetta-ingestion pyroaring
+```
+
+**构建bitmap对象**：
+
+```python
+tags = [i for i in range(1, 21, 2)]
+bitmap = pyroaring.BitMap64(tags)
+row.set_value('preference_tags', bitmap)
+```
+
+## 最佳实践
+
+1. **选择合适的数据类型**：当需要存储整数集合时，优先考虑 Bitmap，尤其是集合较大或稀疏的场景
+
+2. **在数据库层完成运算**：充分利用 Bitmap 的集合运算函数，在数据库层完成交集、并集等操作，减少数据传输
+
+3. **合理使用转换函数**：
+
+   1. 使用 `bitmap_to_array` 进行展示和调试
+   2. 使用 `bitmap_to_binary` 进行持久化存储
+
+4. **性能优化**：
+
+   1. 对大规模数据集进行集合运算时，使用 Bitmap 而非 Array
+   2. 使用 `bitmap_cardinality` 进行计数而非转换为数组后计数

+## 🎯 业务场景实战案例
+
+### 场景1: 多渠道用户重叠分析
+
+#### 💡 为什么要做这个分析？
+
+营销团队在多个渠道（Facebook、Google、TikTok等）投放广告获取用户，但面临以下挑战：
+
+* **重复投放成本**: 不知道有多少用户在多个渠道都看到了广告，造成预算浪费
+* **渠道效果对比**: 无法准确评估哪个渠道带来的是独有用户，哪个渠道主要是重复用户
+* **投放策略优化**: 需要了解用户重叠程度来调整各渠道的投放比例和预算分配
+* **精准营销**: 识别只在单一渠道活跃的用户，进行针对性的跨渠道营销
+
+通过BITMAP函数可以高效计算数百万用户在不同渠道间的重叠情况，为营销决策提供数据支撑。
+
+#### 1.1 建表准备
+
+```sql
+-- 创建用户活动表
+CREATE TABLE IF NOT EXISTS user_activity (
+    user_id BIGINT,
+    channel STRING,
+    activity_date DATE,
+    event_type STRING
+) PARTITIONED BY (activity_date);
+
+-- 插入示例数据
+INSERT INTO user_activity VALUES
+(1001, 'facebook', DATE('2024-01-15'), 'register'),
+(1002, 'google', DATE('2024-01-15'), 'register'),
+(1003, 'tiktok', DATE('2024-01-15'), 'register'),
+(1001, 'google', DATE('2024-01-16'), 'login'),
+(1004, 'facebook', DATE('2024-01-16'), 'register'),
+(1005, 'google', DATE('2024-01-16'), 'register'),
+(1006, 'tiktok', DATE('2024-01-16'), 'register'),
+(1007, 'facebook', DATE('2024-01-17'), 'register'),
+(1008, 'google', DATE('2024-01-17'), 'register'),
+(1009, 'tiktok', DATE('2024-01-17'), 'register'),
+(1002, 'tiktok', DATE('2024-01-17'), 'login');
+```
+
+#### 1.2 渠道用户重叠分析
+
+< c2.channel;
+```
+
+**预期结果**: 返回重叠用户ID [1001]，符合业务逻辑。
+
+### 场景2: 用户兴趣推荐系统
+
+#### 💡 为什么要做这个分析？
+
+电商平台面临个性化推荐的挑战：
+
+* **商品推荐精准度**: 需要基于用户真实的购买和浏览行为，而不是简单的热门商品推荐
+* **相似用户发现**: 识别兴趣相似的用户群体，实现协同过滤推荐
+* **新用户冷启动**: 通过分析用户初期行为，快速找到相似用户进行推荐
+* **推荐多样性**: 在保证相关性的同时，避免推荐内容过于单一
+* **实时性要求**: 用户行为变化后，需要快速更新推荐结果
+
+使用BITMAP函数可以高效计算用户兴趣向量的相似度，支撑实时推荐系统的运行。
+
+#### 2.1 建表准备
+
+```sql
+-- 创建用户行为表
+CREATE TABLE IF NOT EXISTS user_behavior (
+    user_id BIGINT,
+    item_id BIGINT,
+    behavior_type STRING,  -- 'view', 'cart', 'purchase'
+    behavior_date DATE
+) PARTITIONED BY (behavior_date);
+
+-- 创建商品分类表
+CREATE TABLE IF NOT EXISTS item_category (
+    item_id BIGINT,
+    category_id INT,
+    category_name STRING
+);
+
+-- 插入示例数据
+INSERT INTO user_behavior VALUES
+(1001, 1, 'view', DATE('2024-01-15')),
+(1001, 2, 'purchase', DATE('2024-01-15')),
+(1001, 5, 'view', DATE('2024-01-15')),
+(1002, 1, 'view', DATE('2024-01-15')),
+(1002, 3, 'purchase', DATE('2024-01-15')),
+(1002, 4, 'cart', DATE('2024-01-15')),
+(1003, 2, 'view', DATE('2024-01-16')),
+(1003, 5, 'purchase', DATE('2024-01-16')),
+(1003, 6, 'view', DATE('2024-01-16')),
+(1004, 1, 'purchase', DATE('2024-01-16')),
+(1004, 4, 'view', DATE('2024-01-16'));
+
+INSERT INTO item_category VALUES
+(1, 101, '电子产品'),
+(2, 101, '电子产品'),
+(3, 102, '服装'),
+(4, 102, '服装'),
+(5, 103, '图书'),
+(6, 103, '图书');
+```
+
+#### 2.2 计算用户兴趣相似度
+
+```sql
+-- 基于用户行为计算兴趣相似度
+WITH user_interests AS (
+  SELECT 
+    ub.user_id,
+    group_bitmap_state(ic.category_id) as interest_categories
+  FROM user_behavior ub
+  JOIN item_category ic ON ub.item_id = ic.item_id
+  WHERE ub.behavior_date >
+
+**业务价值**: 用户 1001 和 1004 在电子产品分类上相似度 100%，推荐逻辑精准。
+
+#### 2.3 为用户推荐相似用户购买的商品
+
+```sql
+-- 为指定用户推荐相似用户购买的商品
+WITH target_user_interests AS (
+  SELECT group_bitmap_state(ic.category_id) as interests
+  FROM user_behavior ub
+  JOIN item_category ic ON ub.item_id = ic.item_id
+  WHERE ub.user_id = 1001 
+    AND ub.behavior_type IN ('purchase', 'cart')
+),
+similar_users AS (
+  SELECT 
+    ub.user_id,
+    group_bitmap_state(ic.category_id) as interests
+  FROM user_behavior ub
+  JOIN item_category ic ON ub.item_id = ic.item_id
+  WHERE ub.user_id != 1001
+    AND ub.behavior_type IN ('purchase', 'cart')
+  GROUP BY ub.user_id
+  HAVING bitmap_and_cardinality(
+    group_bitmap_state(ic.category_id), 
+    (SELECT interests FROM target_user_interests)
+  ) >= 1
+),
+user_purchased_items AS (
+  SELECT group_bitmap_state(item_id) as purchased_items
+  FROM user_behavior 
+  WHERE user_id = 1001 AND behavior_type = 'purchase'
+)
+SELECT 
+  ub.item_id,
+  ic.category_name,
+  COUNT(DISTINCT ub.user_id) as recommended_by_users,
+  ARRAY_AGG(DISTINCT ub.user_id) as recommending_users
+FROM similar_users su
+JOIN user_behavior ub ON su.user_id = ub.user_id
+JOIN item_category ic ON ub.item_id = ic.item_id
+CROSS JOIN user_purchased_items upi
+WHERE ub.behavior_type = 'purchase'
+  AND NOT bitmap_contains(upi.purchased_items, ub.item_id)  -- 排除已购买商品
+GROUP BY ub.item_id, ic.category_name
+ORDER BY recommended_by_users DESC;
+```
+
+**业务价值**: 为用户1001推荐 item_id=1（电子产品），由用户1004推荐，实现精准协同过滤。
+
+### 场景3: A/B测试效果分析
+
+#### 💡 为什么要做这个分析？
+
+产品团队在进行A/B测试时面临精确度和效率的双重挑战：
+
+* **样本污染问题**: 需要确保实验组和对照组用户没有交叉，避免测试结果失真
+* **转化路径分析**: 不只看最终转化率，还要分析用户在不同实验版本下的行为路径差异
+* **统计显著性**: 需要精确计算各组的用户数量和转化数量，确保测试结果可信
+* **实验效果评估**: 快速识别哪些用户群体对实验变化更敏感
+* **后续决策支持**: 为产品迭代和全量发布提供数据依据
+
+BITMAP函数可以精确追踪实验用户的行为表现，避免传统方法中的近似计算误差。
+
+#### 3.1 建表准备
+
+```sql
+-- 创建A/B测试分组表
+CREATE TABLE IF NOT EXISTS ab_test_assignments (
+    user_id BIGINT,
+    experiment_id STRING,
+    group_name STRING,
+    assignment_date DATE
+);
+
+-- 创建转化事件表
+CREATE TABLE IF NOT EXISTS conversion_events (
+    user_id BIGINT,
+    experiment_id STRING,
+    event_type STRING,
+    event_date DATE,
+    event_value DECIMAL(10,2)
+);
+
+-- 插入示例数据
+INSERT INTO ab_test_assignments VALUES
+(1001, 'homepage_redesign_2024', 'control', DATE('2024-01-01')),

+(1008, 'homepage_redesign_2024', 'purchase', DATE('2024-01-20'), 199.99);
+```
+
+#### 3.2 A/B测试转化分析
+
+```sql
+-- A/B测试组转化效果对比分析
+WITH experiment_groups AS (
+  SELECT 
+    group_name,
+    group_bitmap_state(user_id) as users
+  FROM ab_test_assignments
+  WHERE experiment_id = 'homepage_redesign_2024'
+  GROUP BY group_name
+),
+conversion_analysis AS (
+  SELECT 
+    ata.group_name,
+    ce.event_type,
+    group_bitmap_state(ce.user_id) as converted_users
+  FROM ab_test_assignments ata
+  JOIN conversion_events ce ON ata.user_id = ce.user_id 
+    AND ata.experiment_id = ce.experiment_id
+  WHERE ata.experiment_id = 'homepage_redesign_2024'
+    AND ce.event_date BETWEEN '2024-01-01' AND '2024-01-31'
+  GROUP BY ata.group_name, ce.event_type
+)
+SELECT 
+  eg.group_name,
+  ca.event_type,
+  bitmap_cardinality(eg.users) as total_users,
+  COALESCE(bitmap_and_cardinality(eg.users, ca.converted_users), 0) as converted_users,
+  ROUND(COALESCE(bitmap_and_cardinality(eg.users, ca.converted_users), 0) * 100.0 / 
+        bitmap_cardinality(eg.users), 2) as conversion_rate,
+  bitmap_to_array(COALESCE(bitmap_and(eg.users, ca.converted_users), NULL)) as converted_user_ids
+FROM experiment_groups eg
+LEFT JOIN conversion_analysis ca ON eg.group_name = ca.group_name
+ORDER BY eg.group_name, ca.event_type;
+```
+
+**分析结果**:
+
+* Control组: 4用户，购买转化25%，注册转化25%
+* Variant\_A组: 4用户，购买转化50%，注册转化50%
+* 实验组效果明显优于对照组
+
+#### 3.3 用户行为路径分析
+
+```sql
+-- 分析不同组用户的行为路径差异
+WITH group_behaviors AS (
+  SELECT 
+    ata.group_name,
+    ce.event_type,
+    group_bitmap_state(ce.user_id) as users_with_event
+  FROM ab_test_assignments ata
+  JOIN conversion_events ce ON ata.user_id = ce.user_id
+  WHERE ata.experiment_id = 'homepage_redesign_2024'
+  GROUP BY ata.group_name, ce.event_type
+)
+SELECT 
+  gb1.group_name,
+  gb1.event_type as first_event,
+  gb2.event_type as second_event,
+  bitmap_and_cardinality(gb1.users_with_event, gb2.users_with_event) as users_both_events,
+  ROUND(bitmap_and_cardinality(gb1.users_with_event, gb2.users_with_event) * 100.0 / 
+        bitmap_cardinality(gb1.users_with_event), 2) as conversion_rate_to_second
+FROM group_behaviors gb1
+JOIN group_behaviors gb2 ON gb1.group_name = gb2.group_name 
+  AND gb1.event_type != gb2.event_type
+WHERE gb1.event_type = 'signup' AND gb2.event_type = 'purchase'
+ORDER BY gb1.group_name;
+```
+
+**分析结果**: 数据中 signup 和 purchase 用户无重叠，转化率为 0%，符合实际数据情况。
+
+### 场景4: 用户生命周期与留存分析

+### 场景5: 权限管理与用户分组
+
+#### 💡 为什么要做这个分析？
+
+企业权限管理系统面临复杂性和性能的双重挑战：
+
+* **权限验证效率**: 传统的表关联查询权限效率低，无法支撑高并发访问
+* **权限组合复杂**: 用户可能同时拥有多个角色，需要快速计算权限并集
+* **审计和合规**: 需要快速查询谁拥有特定权限，支持安全审计需求
+* **权限分析统计**: 分析不同部门、角色的权限分布，发现权限设计问题
+* **动态权限管理**: 支持权限的动态分配和回收，实时生效
+* **扩展性要求**: 随着组织结构变化，权限系统需要支持快速扩展
+
+使用位运算和BITMAP可以将复杂的权限计算转换为高效的位操作，大幅提升系统性能。
+

+
+**部门权限分布**: Engineering 部门高权限级别，Finance 部门只读权限但有审计功能，权限分布合理。
+
+### 场景6: 大规模数据分页与采样
+
+#### 💡 为什么要做这个分析？
+
+数据科学团队在处理海量用户数据时面临性能和资源限制：
+
+* **查询性能优化**: 百万级用户数据的全量查询会导致系统超时或资源耗尽
+* **数据采样需求**: 机器学习训练需要高质量的样本数据，不能简单随机采样
+* **分页展示要求**: 前端系统需要分页展示用户列表，要求响应速度快
+* **内存使用控制**: 避免大结果集导致的内存溢出问题
+* **并发查询支持**: 多个数据分析师同时查询时，需要控制单个查询的资源占用
+* **数据探索效率**: 快速获取数据子集进行探索性分析
+
+BITMAP的分页和采样功能可以高效处理大规模用户数据，支持灵活的数据探索需求。
+

+SELECT user_id FROM table1 t1 JOIN table2 t2 ON t1.id = t2.id
+
+-- ✅ 正确: 明确指定表别名
+SELECT t1.user_id FROM table1 t1 JOIN table2 t2 ON t1.id = t2.id
+```
+
+### 6. 数组访问语法问题
+
+```sql
+-- ❌ 错误: 数组访问可能越界或语法不正确
+SELECT array_col[size(array_col)] 
+
+-- ✅ 正确: 使用0-based索引和边界检查
+SELECT CASE 
+  WHEN size(array_col) > 0 
+  THEN array_col[size(array_col)-1] 
+  ELSE NULL 
+END
+```
+
+### 7. CTE重复引用问题
+
+```sql
+-- ❌ 可能有问题: UNION ALL中多次引用同一CTE
+WITH base_data AS (SELECT ...)
+SELECT ... FROM base_data
+UNION ALL
+SELECT ... FROM base_data  -- 可能导致重复结果
+
+-- ✅ 建议: 简化查询结构或使用临时表
+```
+
+***
+
+## 🎯 优化建议
+
+### 1. 性能优化
+
+* **优先使用基数计算函数**: 当只需要数量时，使用`bitmap_xxx_cardinality()`而不是先构建再计算
+* **合理使用聚合**: 批量处理时使用`group_bitmap_state()`而不是多次单独查询
+* **避免中间结果**: 直接计算最终结果，减少临时bitmap对象的创建
+
+### 2. 内存优化
+
+* **及时转换显示**: bitmap对象仅用于计算，显示时立即转换为数组
+* **避免不必要的完整集合构建**: 能用基数计算就不构建完整bitmap
+* **分页处理大数据**: 使用`bitmap_subset_limit()`进行分页，避免一次性加载所有数据
+
+### 3. 业务逻辑优化
+
+* **合理设计位权限**: 权限位掩码设计要考虑未来扩展性
+* **用户分组策略**: 根据业务需要选择合适的bitmap分组维度
+* **采样策略**: 大数据分析时合理使用采样减少计算成本
+
+### 4. SQL编写最佳实践
+
+* **明确列名**: JOIN查询中必须使用表别名避免歧义
+* **边界检查**: 数组访问前进行长度检查
+* **简化CTE**: 避免复杂的CTE嵌套和重复引用
+

+# BloomFilter Index
+## Bloom Filter索引的原理介绍
+1. **数据结构**：Bloom Filter 由一个位数组（BitSet）和多个哈希函数组成。位数组初始时所有位都设置为 0。
+2. **元素添加**：当向集合中添加一个元素时，通过多个哈希函数计算出该元素在位数组中的多个位置，并将这些位置的位设置为1。
+3. **元素查询**：查询元素是否存在时，同样通过哈希函数计算出该元素可能在位数组中的位置，检查这些位置是否都为1。如果所有位都为1，则认为元素可能存在于集合中；如果任何一个位不为1，则可以确定元素不存在于集合中。
+4. **优点**：
+   * 空间效率和查询时间都远远超过一般算法，存储空间和插入/查询时间都是常数 O(k)。
+   * 哈希函数相互之间没有关系，方便硬件并行实现。
+   * 不需要存储元素本身，在对保密要求严格的场合有优势。
+5. **缺点**：
+   * 随着存入的元素数量增加，误判率随之增加，即假阳性（False Positive）概率增加。
+   * 一般情况下不能从Bloom Filter中删除元素。
+6. **应用场景**：
+   * Bloom Filter 索引适用于基数较高的列，如 ID 列，可以快速判断表的数据文件中是否可能包含要查询的数据，如果不包含就跳过，从而减少扫描的数据量。
+   * 适用于等值查询（包括 = 和 IN），对高基数字段效果较好，如 USER-ID 等唯一 ID 字段。对低基数字段的加速效果有限，如“性别”字段。
+
+7. **误判率（False Positive）**：Bloom Filter 可能出现将不在集合中的元素误判为在集合中的情况，但绝不会出现将集合中的元素误判为不在集合中的情况。
+## Bloom Filter在Lakehouse中的应用
+
+Bloom Filter 索引是一种高效的数据结构，用于快速判断数据文件中是否包含特定的数据。通过为某个列创建 Bloom Filter 索引，系统会为该列生成一个 Bloom Filter。在执行查询操作时，可以利用这个索引跳过不需要的数据文件，从而减少扫描数据量，提高查询性能。Bloom Filter 特别适用于基数较高的列。
+
+例如，当执行一个查询操作，如 `SELECT * FROM table WHERE col_name = 'xxx'`，BloomFilter 会先判断目标数据文件中是否可能包含该值。如果不可能存在，系统将跳过该文件，避免不必要的读取。如果索引判断文件中可能存在目标数据，则会读取文件进行进一步查询。
+
+BloomFilter 索引在以下操作中生效：`AND`, `OR`, `IN`, `=`。需要注意的是，创建完 Bloom Filter 索引后，只有新写入的数据才会包含该索引。对于旧数据，建议使用 `INSERT OVERWRITE` 语句进行重写，以添加索引。
+
+### Bloom Filter具体使用场景
+
+**场景一：大数据量下的等值查询**
+
+**案例**：
+假设有一个用户表 `users`，其中包含数百万条用户记录，表结构如下：
+
+```SQL
+CREATE TABLE users (
+    user_id INT,
+    username VARCHAR(255),
+    email VARCHAR(255)
+);
+```
+
+在这个表中，`email` 字段的基数很高，即大多数用户都有唯一的邮箱地址。如果我们经常需要根据邮箱地址来查询用户信息，可以为 `email` 字段创建一个 Bloom Filter 索引。
+
+**创建索引**：
+
+```SQL
+CREATE BLOOMFILTER INDEX idx_email ON TABLE users(email);
+```
+
+**查询**：
+
+当我们需要查询特定邮箱的用户时，可以使用如下查询：
+
+```SQL
+SELECT * FROM users WHERE email = 'user@example.com';
+```
+
+* **快速排除**：Bloom Filter 可以帮助数据库快速判断 `user@example.com` 是否可能在表中。如果 Bloom Filter 确定该邮箱不可能在表中，那么相关的数据文件将被跳过，从而减少 I/O 操作和查询时间。
+* **提升性能**：对于大数据量的表，这种快速排除可以显著提升查询性能。
+
+**场景二：高基数列的查询优化**
+
+**案例**：
+
+假设有一个商品表`products`，其中包含商品的各种属性，表结构如下：
+
+```SQL
+CREATE TABLE products (
+    product_id INT,
+    category VARCHAR(100),
+    price DECIMAL(10, 2)
+);
+```
+
+在这个表中，`category` 字段的基数非常高，因为商品可以属于不同的类别。如果我们经常需要根据类别来查询商品，可以为 `category` 字段创建一个 Bloom Filter 索引。
+
+**创建索引**：
+
+```SQL
+CREATE BLOOMFILTER INDEX idx_category ON TABLE products(category);
+```
+
+**查询**：
+
+当我们需要查询特定类别的商品时，可以使用如下查询：
+
+```SQL
+SELECT * FROM products WHERE category = 'Electronics';
+```
+
+*   **减少扫描**：Bloom Filter 可以减少需要扫描的数据量，因为对于不包含目标类别的数据文件，Bloom Filter 可以帮助跳过它们。
+*   **提高效率**：在高基数列上，Bloom Filter 可以提高查询效率，尤其是在数据量庞大的情况下。
+
+### 注意事项
+
+* **误报概率**：Bloom Filter有一个定义的误报概率（FPP），这意味着它可能会错误地认为某个值存在于表中。因此，即使Bloom Filter表明某个值可能存在，实际查询时仍可能找不到该值。
+* **写操作成本**：Bloom Filter 在写操作（如插入、更新、删除）时可能会有更高的成本，因为需要更新 Bloom Filter 数据结构。
+* **不支持的数据类型**：Bloom Filter不支持interval、struct、map、array等复杂数据类型，因此在创建索引时需要注意列的数据类型。
+
+
+## 创建 Bloom Filter 索引
+
+[创建 BloomFilter索引](<CREATE-BLOOMFILTER-INDEX.md>)
+
+要为某个列创建 Bloom Filter 索引，您可以使用以下语句：
+
+```
+CREATE BLOOMFILTER INDEX index_name ON table_name (column_name);
+```
+
+例如，为表 `employees` 中的 `email` 列创建一个名为 `email_bloomfilter` 的索引：
+
+```
+CREATE BLOOMFILTER INDEX email_bloomfilter ON employees (email);
+```
+
+## 查看 Bloom Filter 索引详情
+
+[查看BOOLFILTER索引详情](<DESC-INDEX.md>)
+
+要查看表上的 BloomFilter 索引详情，可以使用 `DESCRIBE INDEX` 语句：
+
+```
+DESCRIBE INDEX index_name ON table_name;
+```
+
+例如，查看 `employees` 表上名为 `email_bloomfilter` 的索引详情：
+
+```
+DESCRIBE INDEX email_bloomfilter ON employees;
+```
+
+## 删除 Bloom Filter 索引
+
+[删除 BloomFilter索引](<DROP-INDEX.md>)
+
+
+要删除一个 Bloom Filter 索引，可以使用 `DROP INDEX` 语句：
+
+```
+DROP INDEX index_name ON table_name;
+```
+
+例如，删除 `employees` 表上名为 `email_bloomfilter` 的索引：
+
+```
+DROP INDEX email_bloomfilter ON employees;
+```
+
+## 列出表上的 Bloom Filter 索引
+
+[列出表上的 BloomFilter索引](<SHOW-INDEX.md>)
+
+要查看表上的所有 BloomFilter 索引，可以使用 `SHOW INDEXES` 语句：
+
+```
+SHOW INDEXES ON table_name;
+```
+
+例如，查看 `employees` 表上的所有索引：
+
+```
+SHOW INDEXES ON employees;
+```

+## 构建索引
+
+对存量数据添加索引。目前只支持向量索引和倒排索引，不支持布隆过滤器。
+
+## 语法
+
+```SQL
+-- 语法 1，默认给全表的存量数据加上索引
+BUILD INDEX index_name ON [schema].table_name;
+-- 语法 2，可指定partition，可指定一个或多个,支持=, !=, >, >=, <, <=
+BUILD INDEX index_name ON table_name WHERE partition_name1 = '1' and partition_name2 = '2';
+```
+
+* `index_name`：指定要添加的索引名称
+* 支持指定分区构建：可以指定一个或多个分区
+
+## 说明
+
+执行 `BUILD INDEX` 是一个同步任务，执行过程会消耗计算资源。查看进度可以通过 Job Profile。
+
+当分区表数据量较大时，建议以分区为粒度依次创建索引。

+## 📈 性能优化建议
+
+### 1. 数据存储优化
+
+```python
+# 使用分区表提高查询性能
+create_partitioned_table_sql = """
+CREATE TABLE rag_documents_partitioned (
+    id String,
+    content String,
+    embedding Array(Float32),
+    metadata String,
+    created_at Timestamp DEFAULT CURRENT_TIMESTAMP
+)
+PARTITION BY toYYYYMM(created_at)
+"""
+
+# 建立适当的索引
+create_indexes_sql = [
+    "CREATE INDEX idx_metadata ON rag_documents (metadata)",
+    "CREATE INVERTED INDEX idx_content ON rag_documents (content) WITH ANALYZER='ik'",
+    "CREATE VECTOR INDEX idx_embedding ON rag_documents (embedding)"
+]
+```
+
+### 2. 检索优化
+
+```python
+# 缓存频繁查询的结果
+from functools import lru_cache
+
+class CachedRetriever:
+    def __init__(self, retriever):
+        self.retriever = retriever
+
+    @lru_cache(maxsize=100)
+    def cached_search(self, query: str, k: int = 5):
+        return self.retriever.invoke(query)
+```
+
+### 3. 批处理优化
+
+```python
+# 批量添加文档
+def batch_add_documents(document_store, documents, batch_size=100):
+    for i in range(0, len(documents), batch_size):

+# Lakehouse Bulkload 快速入门
+
+## 简介
+
+Bulkload 是 Lakehouse 提供的一种面向高吞吐量设计的批量数据写入接口，特别适合处理大量连续写入的场景。使用 Bulkload 写入的数据在提交后即可查看。
+
+## 批量导入原理
+
+批量上传 SDK 提供了一种高效的数据导入机制，适用于云器 Lakehouse。以下是其工作原理的简化描述和流程图：
+
+1. **数据上传**：通过SDK，您的数据首先被上传到对象存储服务。这一步骤的性能受到本地网络速度和并发连接数的影响。
+2. **触发导入**：数据上传完成后，当您调用`bulkloadStream.close()`方法时，SDK会自动触发一个SQL命令，将数据从对象存储导入到Lakehouse的表中。不建议您在一个任务中频繁调用`bulkloadStream.close()`，该方法最终只能调用一次。
+3. **计算资源**：上传数据建议选择[通用型计算集群](../create_cluster.md)（GENERAL PURPOSE VIRTUAL CLUSTER）通用型计算资源，它更适合运行批量作业和加载数据作业。数据从对象存储到Lakehouse表的导入速度取决于您配置的计算资源的大小。
+4. **分片上传优化**：处理大于1GB的压缩数据时，建议在`createRow`方法中为每个并发线程或进程分配唯一的分片ID。这种做法能够充分发挥多线程或多进程的并行处理优势，显著提升数据导入效率。最佳实践是根据并发数量来确定分片 ID 的数量，确保每个并发任务对应一个独立的分片 ID。如果多个并发任务被分配了相同的分片 ID，最终写入的数据可能会发生覆盖，导致先前写入的数据丢失。为确保所有分片的数据都被正确导入表中，请在所有并发操作完成后，调用`bulkloadStream.close()`方法来提交整个导入任务。
+
+以下是批量导入原理的流程图：
+
+```
+[SDK上传数据] ──> [对象存储] ──> [调用bulkloadStream.close()]
+                                ↓
+                         [触发SQL命令] ──> [Lakehouse表]
+```
+
+## 适用场景
+
+批量上传文件的 SDK 特别适用于以下情况：
+
+* **一次性大量数据导入**：当您需要导入大量数据时，无论是一次性的批量任务，还是周期性但间隔较长的操作。
+* **导入频率不高**：如果您的数据导入频率不高（时间间隔大于五分钟），即使单次导入的数据量不大，使用批量导入 SDK 也是合适的。
+
+## 不适用场景
+
+批量上传文件的 SDK 不适用于以下情况：
+
+* **实时数据导入**：如果您需要在极短时间内（如5分钟之内）频繁导入数据，建议使用实时数据接口，以满足对实时性的要求。

+
+* [下载地址一](https://central.sonatype.com/artifact/com.clickzetta/clickzetta-java/versions)
+* [下载地址二](https://mvnrepository.com/artifact/com.clickzetta/clickzetta-java)
+
+
+## 创建 BulkloadStream
+
+要通过 ClickZetta 客户端创建一个批量写入流，请参考以下示例代码：
+
+```java
+RowStream stream = client.newBulkloadStreamBuilder()
+        .schema(schema)
+        .table(TABLE_NAME)
+        .operate(RowStream.BulkLoadOperate.APPEND)
+        .build();
+```
+
+### Options
+
+在clickzetta-java版本3.0.18以后提供了options。options用于指定上传选项入指定分取
+
+```
+bulkloadStream=client.newBulkloadStreamBuilder().schema(schema).table(table)
+                .options(BulkLoadOptions.newBuilder().withPartitionSpecs(Optional.of("your_partition_spec")).build())
+
+                .operate(RowStream.BulkLoadOperate.APPEND)
+                .build();
+```
+
+* withPartitionSpecs 用于指定目标表的分区信息，控制数据写入的分区行为。
+
+  * 非分区表：忽略此参数或设置为
+  * 分区表：
+    * 静态分区写入，需要将所有数据写入指定的固定分区，无论源数据中分区列的实际值是什么，写入目标表时都会使用 `partition_spec` 指定的分区值，所有数据都会写入到同一个指定分区中。参数格式是'分区列1=值1,分区列2=值2'
+      - 动态分区写入，根据数据中分区列的实际值，自动写入到对应分区。忽略此参数，系统根据数据中分区列的值自动创建或写入相应分区
+
+### 操作类型
+
+在创建 Bulkload 时，可以通过 `operate` 方法指定以下操作类型：
+
+* `RowStream.BulkLoadOperate.APPEND`：追加模式，向表中添加数据。
+  ```
+  bulkloadStream=client.newBulkloadStreamBuilder().schema(schema).table(table)
+          .operate(RowStream.BulkLoadOperate.APPEND)
+          .build();
+  ```
+
+* `RowStream.BulkLoadOperate.OVERWRITE`：覆盖模式，删除表中现有数据后再写入新数据。
+  ```
+  bulkloadStream=client.newBulkloadStreamBuilder().schema(schema).table(table)
+          .operate(RowStream.BulkLoadOperate.OVERWRITE)
+          .build();
+  ```
+
+## 写入数据
+
+使用 Row 对象表示要写入的具体数据。通过调用 `row.setValue` 方法将数据封装到 Row 对象中。
+
+```java
+Row row = stream.createRow(0);
+row.setValue("id", t);
+row.setValue("name", String.valueOf(t));
+stream.apply(row, 0);
+```
+
+* `createRow` 方法创建 Row 对象时，需要传入一个整数作为分片 ID。这个 ID 可以配合多线程/进程技术，用多个互补相同的分片 ID 来写入数据，从而有效提升写入数据的速度。
+* `setValue` 方法的第一个参数为字段名，第二个参数为具体的数据。要求数据类型与表类型一致。
+* `apply` 方法用于写入数据，需要指定 Row 对象以及相应的分片 ID。
+
+### 写入复杂类型数据
+
+```java
+// 写入数组
+row.setValue("col1", Arrays.asList("first", "b", "c"));
+
+// 写入映射
+final HashMap<Integer, String> map = new HashMap<Integer, String>();
+map.put(t, "first" + t);
+row.setValue("col2", map);
+
+// 写入结构体
+Map<String, Object> struct = new HashMap<>();
+struct.put("first", "first-" + i);
+struct.put("second", i);
+row.setValue("col3", struct);
+```
+
+## 提交数据
+
+批量写入的数据只有在提交之后才可见。因此，提交过程非常重要。
+
+```java
+bulkloadStream.close();
+```
+
+* 通过 `bulkloadStream.getState()` 获取 BulkloadStream 的状态。
+* 如果提交失败，可以通过 `bulkloadStream.getErrorMessage()` 获取错误信息。
+
+## 使用示例
+
+以下是一个使用 Bulkload 写入复杂类型数据的示例：
+
+```java
+// 建表 create table complex_type(col1 array<string>,col2 map<int,string>, col3 struct<x:int,y:int>);
+import com.clickzetta.client.ClickZettaClient;

+            struct.put("y", t+1);
+            row.setValue("col3", struct);
+            bulkloadStream.apply(row, 0);
+        }
+        // 必须调用 stream close 接口，触发提交动作
+        bulkloadStream.close();
+
+        // 轮训提交状态，等待提交结束
+        while(bulkloadStream.getState() == StreamState.RUNNING) {

+# 使用 Python 批量上传数据（BulkLoadV1）
+
+
+
+Clickzetta Lakehouse 通过 `clickzetta-connector` 包提供了使用 Python 语言进行批量数据上传（Bulkload）的 API。该 API 使得数据可以直接从客户端发送到存储系统，传输过程不消耗计算资源，数据在显式 commit 后可见（commit 过程会消耗少量计算资源）。适用于高吞吐、对数据新鲜度（data freshness）要求相对宽松的场景。
+
+通过 Bulkload 相关 API，可以实现单线程数据上传。
+
+安装
+
+如果安装过旧版本的 SDK，先卸载避免冲突：
+
+```shell
+pip uninstall clickzetta-connector clickzetta-connector-python clickzetta-sqlalchemy clickzetta-ingestion-python clickzetta-ingestion-python-v2 -y
+```
+
+> 卸载前请记录好旧版本的包，以防需要回退。查看已安装包版本命令：
+
+```shell
+pip show clickzetta-connector clickzetta-sqlalchemy clickzetta-ingestion-python clickzetta-ingestion-python-v2 clickzetta-connector-python
+```
+
+安装最新版本（要求 Python >=3.7）：
+
+```bash
+pip install clickzetta-connector -U -i https://pypi.org/simple/
+```
+
+
+## 批量导入原理
+
+批量上传的 SDK 提供了一种高效的数据导入机制，适用于 Clickzetta Lakehouse。以下是其工作原理的简化描述和流程图：
+
+1. **数据上传**：通过SDK，您的数据首先被上传到对象存储服务。这一步骤的性能受到本地网络速度和并发连接数的影响。
+2. **触发导入**：数据上传完成后，当您调用`bulkloadStream.commit()`方法时，SDK会自动触发一个SQL命令，将数据从对象存储导入到Lakehouse的表中。不建议您在一个任务中频繁调用`bulkloadStream.commit()`，该方法最终只能调用一次。
+3. **计算资源**：上传数据建议选择[通用型计算集群](../create_cluster.md)（GENERAL PURPOSE VIRTUAL CLUSTER）通用型计算资源，它更适合运行批量作业和加载数据作业。数据从对象存储到 Lakehouse 表的导入速度取决于您配置的计算资源的大小。
+4. **分片上传优化**：处理大于1GB的压缩数据时，建议在`createRow`方法中为每个并发线程或进程分配唯一的分片ID。这种做法能够充分发挥多线程或多进程的并行处理优势，显著提升数据导入效率。最佳实践是根据并发的数量来确定分片 ID 的数量，确保每个并发对应一个独立的分片 ID。如果多个并发被分配了相同的分片 ID，最终写入的数据可能会发生覆盖，导致先前写入的数据丢失。为确保所有分片的数据都被正确导入表中，请在所有并发操作完成后，调用`bulkloadStream.commit()`方法来提交整个导入任务。
+
+以下是批量导入原理的流程图：
+
+```
+[SDK上传数据] ──> [对象存储] ──> [调用bulkloadStream.close()]
+                                ↓
+                         [触发SQL命令] ──> [Lakehouse表]
+```
+
+## 单线程写入
+
+假设上传数据的目标表为 `public.bulkload_test`，DDL 如下：
+
+```sql
+CREATE TABLE public.bulkload_test (
+    i BIGINT,
+    s STRING,
+    d DOUBLE
+);
+```
+
+单线程模式的完整样例代码：
+
+```python
+from clickzetta import connect
+
+conn = connect(
+    username='your_username',
+    password='your_password',
+    service='<region\_id>.api.clickzetta.com',
+    instance='your_instance',
+    workspace='your_workspace',
+    schema='public',
+    vcluster='default'
+)
+
+bulkload_stream = conn.create_bulkload_stream(schema='public', table='bulkload_test')
+
+writer = bulkload_stream.open_writer(0)
+for index in range(1000000):
+    row = writer.create_row()
+    row.set_value('i', index)
+    row.set_value('s', 'Hello')
+    row.set_value('d', 123.456)
+    writer.write(row)
+writer.close()
+
+bulkload_stream.commit()
+```
+
+## API 分步详解
+
+1. 创建 `connection` 对象，根据您的实际情况替换参数即可：
+   ```python
+   conn = connect(
+       username='your_username',
+       password='your_password',
+       service='<region\_id>.api.clickzetta.com',
+       instance='your_instance',
+       workspace='your_workspace',
+       schema='public',
+       vcluster='default'
+   )
+   ```
+
+| **参数**    | **是否必填** | **描述**                                                                                                                          |
+| --------- | --------- | ------------------------------------------------------------------------------------------------------------------------------- |
+| username  | Y        | 用户名                                                                                                                             |
+| password  | Y        | 密码                                                                                                                              |
+| service   | Y        | 连接 Lakehouse 的地址，例如 <region\_id>.api.clickzetta.com。可以在 Lakehouse Studio 管理 -> 工作空间中看到 JDBC 连接串![](../.topwrite/assets/image_1728887857029.png) |
+| instance  | Y        | 可以在 Lakehouse Studio 管理 -> 工作空间中查看 JDBC 连接串以获取![](../.topwrite/assets/image_1729051500396.png)                                        |
+| workspace | Y        | 使用的工作空间                                                                                                                         |
+| vcluster  | Y        | 使用的 VC                                                                                                                           |
+| schema    | Y        | 访问的 Schema 名                                                                                                                      |
+
+2. 创建 `BulkLoad Stream` 对象，指定上传的目标表、上传方式等：
+   **必选参数**
+   * `table`：表名称
+   **可选参数**
+   * `schema`：如未指定，则使用 `connection` 对象中指定的 `schema`
+    * `operation`
+        * `BulkLoadOperation.APPEND`：增量模式（写入的数据都作为新数据，不对已有数据有任何影响）
+        * `BulkLoadOperation.OVERWRITE`：覆盖模式（清空已有表数据，将新数据写入表中）
+
+* `partition_spec`：用于指定目标表的分区信息，控制数据写入的分区行为。
+    * 非分区表：忽略此参数或设置为空。
+    * 分区表：
+        * 静态分区写入：需要将所有数据写入指定的固定分区。无论源数据中分区列的实际值是什么，写入目标表时都会使用 `partition_spec` 指定的分区值，所有数据都会写入到同一个指定分区中。参数格式为 '分区列1=值1,分区列2=值2'。
+        * 动态分区写入：根据数据中分区列的实际值，自动写入到对应分区。忽略此参数，系统根据数据中分区列的值自动创建或写入相应分区。
+
+  ```python
+
+  from clickzetta.bulkload.bulkload_enums import BulkLoadOperation
+
+  # APPEND 模式构建，默认 operation 即为 APPEND
+  bulkload_stream = conn.create_bulkload_stream(schema='public', table='bulkload_append_test')
+
+
+
+  # OVERWRITE 模式构建
+  bulkload_stream = conn.create_bulkload_stream(
+      schema='public',
+      table='bulkload_overwrite_test',
+      partition_spec='pt=2023-07-01',
+      operation=BulkLoadOperation.OVERWRITE
+  )
+  ```
+
+3. 创建 `writer` 并写入数据：
+   每个 `bulkload stream` 可以创建多个 `writer`，不同的 `writer` 需要用不同的 id 标识。使用多个 `writer` 可以实现在一次 commit 中多线程并发写入的场景。
+   ```python
+   # 利用 `open_writer` 方法创建 `writer`，参数为 `writer` id。单机模式下，只有一个 `writer` id 即可，直接传入 0.
+   writer = bulkload_stream.open_writer(0)
+   ```
+4. 写入数据：
+   ```python
+   # 每一行数据都需要用 create_row() 方法创建 Row 对象，然后用 set_value() 方法写入具体数据。
+   # set_value() 第一个参数为列名，第二个参数为值
+   row = writer.create_row()
+   row.set_value('i', 1)
+   row.set_value('s', 'January')
+   row.set_value('d', 123.456)
+   writer.write(row)
+   ```
+   通过 writer 写入的数据将直接在存储系统中形成相应的 parquet 文件。writer 将根据写入的数据量自动进行文件切割。当 writer 写入数据结束后，需要显式调用 writer.close() 来保证数据完整性。
+   ```python
+   writer.close()
+   ```
+5. 提交 stream。commit 前需要确保各 writer 均已完成写入并关闭。commit 成功后数据在表中可见。
+   ```python
+   bulkload_stream.commit()
+   ```

+# 私有存储（BYOS）
+> 【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请联系我们的技术支持同学协助处理。
+## 一、功能概述
+
+私有存储BYOS（Bring Your Own Storage）功能允许您使用自己的对象存储服务作为ClickZetta Lakehouse的数据存储位置。通过此功能，您可以：
+
+* 在Web界面完成私有存储配置，无需复杂的技术操作；
+* 将工作空间数据存储在您自己云平台账号管理的对象存储中；
+* 自主管理存储成本和存储策略。
+
+## 二、适用场景
+
+BYOS功能适合以下场景：
+
+1. **数据合规要求**：需要将数据存储在自有云账号的对象存储内，以满足合规要求；
+2. **数据主权**：需要完全掌控数据的存储位置和访问权限；
+3. **混合部署**：部分工作空间使用托管存储，部分合规要求高的工作空间使用自有存储。
+
+## 三、前置准备
+
+### 3.1 创建存储桶（Bucket）
+
+在配置BYOS前，您需要先创建符合要求的存储桶：
+
+#### 必须满足的条件：
+
+| 配置项      | 要求                         | 说明                     |
+| -------- | -------------------------- | ---------------------- |
+| **所属区域** | 与Lakehouse实例同一云厂商、同一Region | 避免跨区域传输费用              |
+| **存储类型** | 标准存储                       | 不要使用低频或归档存储，避免产生额外访问费用 |
+| **读写权限** | 私有（私有读写）                   | 确保数据安全                 |
+| **独占使用** | 专用于Lakehouse               | 不可与其他业务系统共用，避免数据冲突     |
+
+#### 存储桶（bucket）建议配置：
+
+| 配置项        | 建议值  | 说明                                             |
+| ---------- | ---- | ---------------------------------------------- |
+| **存储冗余**   | 按需选择 | 本地冗余存储可满足基本需求；高可用要求可选同城冗余。                     |
+| **版本控制**   | 关闭   | Lakehouse已自行管理数据版本，开启可能产生额外费用。                 |
+| **服务端加密**  | 关闭   | Lakehouse会根据工作空间配置，对部分数据单独开启加密。全局开启加密可能影响读写性能。 |
+| **生命周期规则** | 不配置  | Lakehouse自行管理文件生命周期。                           |
+
+### 3.2 创建访问策略
+
+您需要为ClickZetta Lakehouse子账号授权访问您的存储桶。具体的授权策略详见——
+
+## 四、配置步骤
+
+### 步骤1：进入私有存储管理
+
+:-: ![](/.topwrite/assets/image_1760181980735.png =759)
+
+1. 登录ClickZetta Lakehouse控制台
+2. 进入【管理】→【更多】→【私有存储】页面
+3. 点击【+新建】按钮
+
+### 步骤2：填写存储信息
+
+![](/.topwrite/assets/image_1760182222984.png)
+
+在弹出的配置窗口中填写：
+
+1）名称【必填】：以字母（AZ、az）或下划线（“\_”）开头，长度为3\~28个字符。须在您的服务实例内唯一。保存后不可更改。
+
+2）主账号【必填】：输入您在云平台中的账号ID，以便调用云平台接口时使用您授权的角色和Bucket。可在登录云平台账号后找到并复制。
+
+&#x20;     阿里云：
+
+:-: ![](/.topwrite/assets/image_1760182500707.png =253)
+
+&#x20;   腾讯云：
+
+:-: ![](/.topwrite/assets/image_1760182704445.png =250)
+
+3）Bucket名称【必填】：输入您希望使用的Bucket名称，或者Bucket名称+路径。Bucket名称+路径的写法示例为：
+
+```
+bucket_name/subpath
+```
+
+4）描述【非必填】：对私有存储的描述，可帮助使用者了解该私有存储的业务用途，避免误操作。
+
+完成上述信息的填写后，点击“确定”按钮，即完成私有存储的创建。
+
+一个Lakehouse服务实例下可以创建多个私有存储。
+
+### 步骤3：校验配置
+
+创建完成后，私有存储的默认连通状态为“失败”，需要点击私有存储右侧的“测试联通”按钮，测试私有存储的连通性。Lakehouse测试连通性时将进行的操作是：使用Lakehouse在云平台的账号调用同云平台同region的HeadBucket/GetBucketInfo等相似功能的接口，确认：
+
+* 存储桶（Bucket）是否存在；
+* 所在地域是否正确；
+* 访问权限是否配置正确。
+
+校验通过后，列表中该私有存储的连接状态变为“成功”。
+
+### 步骤5：关联工作空间
+
+在创建新的工作空间时，可使用已有的私有存储作为该工作空间的存储位置。
+
+1）在新建工作空间弹窗中，点击并展开【高级设置】；
+
+:-: ![](/.topwrite/assets/image_1760183458961.png =516)
+
+2）打开私有存储开关，选择已有的私有存储位置。一个私有存储位置可以关联多个工作空间。多个工作空间的数据会在该存储桶（bucket）下的子路径中区分开，不会互相影响。
+
+:-: ![](/.topwrite/assets/image_1760183572318.png =516)
+
+3）点击“确定”完成工作空间创建。
+
+## 五、重要限制
+
+### 5.1 功能限制
+
+* 工作空间关联存储后**不可更改**；
+* 已关联工作空间的私有存储位置**不可删除**，须先删除工作空间后才可删除。
+
+### 5.2 区域限制
+
+* 仅支持同一云厂商、同一Region的存储桶；
+* AWS环境需确保在同一可用区，避免跨区流量费用。
+
+### 5.3 责任边界
+
+* 使用私有存储时，私有存储指向存储桶（bucket）的可用性和可靠性由您自行负责；
+* 非经由ClickZetta操作造成的数据问题需由您自行承担。
+
+### 5.4 费用说明
+
+使用BYOS后：
+
+* ClickZetta不再收取私有存储中的存储容量费用，仍继续收取其他托管存储位置中的存储费用。
+* 您需直接向云厂商支付：
+  * 存储容量费用
+  * API访问费用
+  * 公网流量费用（如有）
+* 日志和临时文件将占用您的存储空间
+
+### 5.5 性能注意
+
+* 存储性能直接影响Lakehouse运行效率
+* 需确保存储服务的QPS和带宽满足需求
+* 避免与其他业务争抢存储资源
+
+^
+
+## 六、常见问题
+

+# 策略阿里云私有存储配置
+
+本指南将帮助您在腾讯云对象存储服务（COS）上配置BYOS（私有存储），使ClickZetta Lakehouse能够使用您的OSS存储桶作为数据存储位置。
+
+## 前提条件
+
+* 拥有腾讯云账号并开通COS服务
+* 了解您的ClickZetta Lakehouse实例所在的云平台和地域（Region）
+* 拥有COS存储桶的管理权限
+
+## 步骤一：准备COS存储桶
+
+### 创建新存储桶（推荐）
+
+如果您选择创建新的存储桶专用于ClickZetta Lakehouse：
+
+1. **登录腾讯云COS控制台**
+
+   访问：<https://console.cloud.tencent.com/cos/bucket>
+
+2. **点击"创建Bucket**"
+
+![](/.topwrite/assets/ef4ec49e-2d3e-459b-b649-da670fe4a345.jpeg)
+
+**配置Bucket基本信息**
+
+| 配置项       | 设置值                           | 说明                                            |
+| --------- | ----------------------------- | --------------------------------------------- |
+| **所属地域**  | 与Lakehouse实例相同                | ⚠️ **关键要求**：必须选择与ClickZetta Lakehouse实例相同的地域。 |
+| **名称**    | 自定义（如：`my-company-lakehouse`） | 全局唯一，建议包含用途标识。                                |
+| **访问权限**  | 私有读写                          | 确保数据安全。                                       |
+| **多AZ特性** | 关闭                            | 可根据数据可用行、可靠性需求选择开启。开启将增加云厂商收取的存储费用。           |
+| **版本控制**  | 关闭                            | 避免产生额外费用。                                     |
+| **服务端加密** | 不加密                           | Lakehouse会自行管理加密，全局加密可能影响性能。                  |
+
+其他配置均可选择不开启。
+
+### 使用已有存储桶
+
+如果您选择使用已有的存储桶：
+
+#### 验证地域配置
+
+存储桶必须与ClickZetta Lakehouse实例在同一地域（Region）。例如：
+
+\- Lakehouse实例在：腾讯云-上海
+
+\- COS Bucket必须在：中国-上海
+
+您的服务实例所在“云服务商和地域”信息可在服务实例首页查询到：
+
+:-: ![](/.topwrite/assets/image_1760270239517.png =747)
+
+#### 选择存储路径
+
+您可以选择以下方式之一：
+
+**方式一：使用整个Bucket（推荐**）
+
+适用场景：Bucket专用于Lakehouse。
+
+**方式二：使用Bucket下的特定目录**
+
+适用场景：需要在同一Bucket中隔离不同用途的数据。
+
+***
+
+**数据安全警告**：
+
+1\. 请确保所选路径不与其他业务系统共用；
+
+2\. ClickZetta Lakehouse会对该路径下的文件进行读、写、删除操作；
+
+3\. 共用路径可能导致：  &#x20;
+
+* 数据被意外删除或覆盖
+* 影响其他业务系统的正常运行
+* 数据一致性问题
+
+建议：为Lakehouse创建独立的Bucket或使用独立的目录。
+
+###
+
+### 记录必要信息
+
+请记录以下信息，后续配置时需要使用：
+
+* **Bucket名称**
+* **Bucket所在地域**
+* **您的腾讯云主账号ID**
+
+查看主账号ID的方法：
+
+1. 登录腾讯云控制台
+2. 点击右上角头像
+3. 在"账号信息"中查看"账号ID"
+
+## 步骤二：配置Bucket访问策略
+
+**1. 进入Bucket管理页面**
+
+* 在COS控制台找到您的Bucket，点击Bucket名称进入详情页
+
+**2. 进入权限管理页面**
+
+:-: ![](/.topwrite/assets/39c3600e-2652-4475-a7fa-f2f40bac51e3.jpeg =772)
+
+* 点击左侧菜单"权限管理" 。
+* 在“Policy权限设置”栏点击"添加策略"。
+
+**3. 配置授权策略**
+
+选择"自定义授权"，填写以下信息：
+
+| **配置项**   | **设置值**                                                                        |
+| --------- | ------------------------------------------------------------------------------ |
+| **被授权用户** | 指定用户                                                                           |
+| **资源范围**  | bucket专用于ClickZetta时选择：整个存储桶&#xA;ClickZetta使用指定目录时选择：指定目录                      |
+| **请选择模板** | 自定义策略                                                                          |
+| **效力**    | 允许                                                                             |
+| **用户**    | 选择“主账号”，并填写Clickzetta Lakehouse在腾讯云的主账号：100029595716                           |
+| **资源**    | bucket专用于ClickZetta时选择：整个存储桶&#xA;ClickZetta使用指定目录时选择：指定资源路径，并填写路径。注意在子目录后加/\*。 |
+| **操作**    | 选择“所有操作”。                                                                      |
+| **条件**    | 不添加任何条件。                                                                       |

+# 终止作业
+
+## 功能描述
+
+本功能允许用户终止正在运行的作业或取消某个虚拟集群下的所有作业。通过该功能，用户可以有效地管理作业进度，避免资源浪费。
+
+## 语法说明
+
+```
+-- 取消单个作业
+CANCEL JOB 'jobid';
+
+-- 取消某个VIRTUAL CLUSTER下所有作业
+ALTER VCLUSTER [ IF EXISTS ] vc_name CANCEL ALL JOBS;
+```
+
+## 参数说明
+
+1. `jobid`：作业运行的唯一标识符，字符串格式。作业运行时，日志会打印出jobid，同时在[show jobs](<show-jobs.md>)命令中也会显示相应的jobid。
+2. `vc_name`：指定的虚拟集群名称。如果虚拟集群不存在，使用`IF EXISTS`选项可以避免因找不到集群而产生错误。
+
+## 使用示例
+
+### 示例1：取消单个作业
+
+假设您需要取消一个作业，其jobid为`201xxxxxxxxxx`。您可以使用以下命令实现：
+
+```
+CANCEL JOB '201xxxxxxxxxx';
+```
+
+### 示例2：取消某个虚拟集群下所有作业
+
+假设您需要取消名为`my_vc`的虚拟集群下的所有作业。首先，使用以下命令取消该虚拟集群下的所有作业：
+
+```
+ALTER VCLUSTER my_vc CANCEL ALL JOBS;
+```
+
+如果担心虚拟集群不存在导致错误，可以使用`IF EXISTS`选项：
+
+```
+ALTER VCLUSTER IF EXISTS my_vc CANCEL ALL JOBS;
+```
+
+## 注意事项
+
+* 确保在执行终止作业操作时，输入正确的`jobid`或`vc_name`，以免影响其他作业或虚拟集群的正常运行。
+* 终止作业后，已使用的资源将被释放，但请注意，已消耗的时间和费用可能无法退回。

+```
+
+### 关键洞察
+
+* **问题定位时间**: <= '2025-09-08'
+   GROUP BY date(measurement_start)
+   ORDER BY usage_date
+   ```
+
+2. **异常模式识别**
+
+**历史费用趋势分析**：
+
+| 时间段        | 日均费用       | 费用范围              | 状态          |
+| ---------- | ---------- | ----------------- | ----------- |
+| 8月25日-9月2日 | ¥1.8       | ¥0.99-¥6.06       | ✅ 正常基线      |
+| 9月3日       | ¥25.13     | -                 | ⚠️ 首次异常     |
+| **9月4-5日** | **¥76.21** | **¥66.65-¥85.77** | 🚨 **严重异常** |
+| 9月6日后      | ¥0.73      | ¥0.53-¥1.05       | ✅ 恢复正常      |
+
+3. **使用模式变化分析**
+
+   ```sql
+   SELECT 
+       date(measurement_start) as usage_date,
+       sku_name,
+       count(*) as record_count,
+       sum(measurements_consumption) as total_consumption_hours,
+       avg(measurements_consumption) as avg_consumption_per_record,
+       sum(total_after_discount) as total_cost
+   FROM sys.information_schema.instance_usage 
+   WHERE sku_category = 'compute'
+   GROUP BY date(measurement_start), sku_name
+   ```
+
+**GP集群使用模式对比**：
+
+| 日期       | 平均每小时消费     | 记录数     | 总消费时长       | 单次费用     |
+| -------- | ----------- | ------- | ----------- | -------- |
+| 9月1-2日   | 0.03-0.04小时 | 14-20条  | 0.37-0.76小时 | ¥1-3     |
+| **9月4日** | **0.57小时**  | **42条** | **24.05小时** | **¥3.5** |
+| **9月5日** | **0.58小时**  | **32条** | **18.71小时** | **¥3.5** |
+| 9月6日后    | 0.02小时      | 12条     | 0.20小时      | ¥0.7     |
+
+**关键发现**：
+
+* GP集群从短时查询模式变为长时间运行模式
+* 每小时消费时长增加**15倍**（0.04 → 0.57小时）
+* 接近满1小时计费，说明集群持续运行
+
+### 第三步：精确责任方定位
+
+**用户继续询问**：
+
+```
+看下是哪个实例那个工作空间的集群
+```
+
+**MCP Server多维度分析**：
+
+1. **实例和工作空间费用分布**
+
+   ```sql
+   SELECT 
+       instance_id,
+       workspace_name,
+       sku_name,
+       sum(total_after_discount) as total_cost
+   FROM sys.information_schema.instance_usage 
+   WHERE date(measurement_start) IN ('2025-09-04', '2025-09-05')
+     AND sku_category = 'compute'
+   GROUP BY instance_id, workspace_name, sku_name
+   ORDER BY total_cost DESC
+   ```
+
+**责任方分析结果**：
+
+| 实例ID       | 工作空间                         | 9月4日费用     | 9月5日费用     | 异常程度         |
+| ---------- | ---------------------------- | ---------- | ---------- | ------------ |
+| **270397** | **quick\_start**             | **¥83.48** | **¥64.77** | 🚨 **主要责任方** |
+| 270397     | lakehouse\_quick\_experience | ¥0.71      | ¥0.71      | ✅ 正常         |
+| 270397     | ns227206                     | ¥0.17      | ¥0.17      | ✅ 正常         |
+
+2. **具体集群使用详情**
+
+   ```sql
+   SELECT 
+       date(measurement_start) as usage_date,
+       hour(measurement_start) as usage_hour,
+       measurements_consumption,
+       amount
+   FROM sys.information_schema.instance_usage 
+   WHERE workspace_name = 'quick_start' 
+     AND sku_name = 'GP类型计算集群'
+     AND amount >
+
+**GP集群运行时间分析**：
+
+**9月4日异常模式**：
+
+* **00:00-23:59**：24小时持续运行
+* **每小时消费**：~1.00小时（几乎满小时计费）
+* **单小时费用**：¥3.5左右
+
+**9月5日异常模式**：
+
+* **00:00-18:59**：19小时持续运行
+* **费用模式**：同样接近满小时计费
+
+**关键发现**：
+
+* 问题锁定在 `quick_start` 工作空间的GP集群
+* 集群呈现24小时近乎不间断运行状态
+* **非**正常的短时查询模式
+
+### 第四步：根本原因追踪
+
+**MCP Server自动深入调查**：
+
+1. **作业历史分析**
+
+   <= '2025-09-06 23:59:59'
+   ```
+
+**正常期间作业特征**：
+
+* 查询执行时间：几秒到几分钟
+* 集群自动挂起：查询完成后快速释放
+* 费用模式：按实际使用时间计费
+
+## 问题根源深度解析
+
+### 技术层面分析
+
+**1. 动态表配置错误**
+
+```sql
+-- 问题配置（推测）
+CREATE DYNAMIC TABLE mcp_test_daily_summary
+REFRESH_INTERVAL = '5 MINUTES'  -- ❌ 过于频繁
+AS SELECT ...
+```
+
+**2. 集群资源管理失效**
+
+* **正常模式**: 查询完成 → 集群空闲 → 自动挂起（几分钟内）
+* **异常模式**: 查询完成 → 5分钟后新查询 → 集群持续活跃 → 无法挂起
+
+**3. 费用计算逻辑**
+
+* **按小时计费**: GP集群按使用时长计费，¥3.5/小时
+* **最小计费单位**: 即使使用几分钟，活跃状态会累积计费时间
+* **累积效应**: 5分钟间隔刷新 → 24小时几乎满计费
+
+### 业务影响评估
+
+**1. 直接费用损失**
+
+* **异常期间**: 2天总费用¥152.42
+* **正常期间**: 2天预期费用¥2-12
+* **直接损失**: ¥140-150
+
+**2. 潜在风险**
+
+* **如未及时发现**: 每日额外费用¥80+
+* **月度影响**: 可能产生¥2400+额外费用
+* **资源浪费**: 集群资源未得到有效利用
+
+**3. 系统性问题**
+
+* **配置管理**: 动态表刷新策略缺乏合理性检查
+* **监控告警**: 费用异常未及时发现
+* **资源优化**: 集群自动管理策略需要优化
+
+## 解决方案与最佳实践
+
+### 立即修复措施
+
+**1. 动态表配置修正**
+
+```sql
+-- 检查当前配置
+DESC DYNAMIC TABLE mcp_test_daily_summary;
+
+-- 方案一：调整刷新间隔（推荐）
+ALTER DYNAMIC TABLE mcp_test_daily_summary 
+SET REFRESH_INTERVAL = '1 HOUR';
+
+-- 方案二：根据业务需求调整
+ALTER DYNAMIC TABLE mcp_test_daily_summary 
+SET REFRESH_INTERVAL = '4 HOURS';  -- 或其他合理间隔
+
+-- 方案三：暂停动态表（紧急情况）
+ALTER DYNAMIC TABLE mcp_test_daily_summary SUSPEND;
+```
+
+**2. 集群配置优化**
+
+```sql
+-- 检查集群自动挂起设置
+SHOW VIRTUAL_CLUSTERS;
+
+-- 确保合理的自动挂起时间
+ALTER VIRTUAL_CLUSTER your_gp_cluster 
+SET AUTO_SUSPEND_IN_SECOND = 300;  -- 5分钟自动挂起
+```
+
+### 预防性措施
+
+**1. 监控和告警**
+
+```sql
+-- 创建费用监控视图
+CREATE VIEW daily_cost_monitor AS
+SELECT 
+    date(measurement_start) as cost_date,
+    sum(total_after_discount) as daily_cost,
+    CASE 
+        WHEN sum(total_after_discount) >
+
+**2. 动态表最佳实践**
+
+* **刷新间隔建议**：根据数据更新频率设置，最短不低于30分钟
+* **资源考虑**：评估刷新对计算资源的影响
+* **业务对齐**：刷新频率应匹配实际业务需求
+
+**3. 资源管理策略**
+
+* **集群分离**：将定时任务和交互查询分离到不同集群
+* **时间窗口**：在低峰时段执行资源密集型任务
+* **成本预算**：设置工作空间级别的费用预算和告警

+# CREATE ....CLONE
+
+> 【预览发布】本功能当前处于公开预览发布阶段。
+
+在 Lakehouse 中，克隆表操作创建了一个表的独立副本，该副本与原始表完全分离，互不影响。克隆表在创建时不占用额外的存储空间，因为它共享原始表的数据版本。但是，如果原始表数据发生变化并影响到克隆表中的数据，克隆表将需要为这些变化支付存储费用。克隆表具有与普通表相似的功能，包括查询、复制和删除等操作。Lakehouse 支持克隆普通表和动态表，并且允许创建克隆的克隆，即克隆一个已经是克隆的表。
+
+## 克隆表注意事项
+
+* 克隆操作不会复制原始表的权限，新克隆的表将具有独立的权限设置。
+* 克隆操作不会复制用户设置的属性，包括生命周期和数据时间旅行保留周期。
+* 实时写入且未提交的数据不会被克隆。因此，在克隆完成后，刚刚写入的数据将无法在克隆表中找到。
+* 不支持克隆外部表。
+
+## 普通表克隆
+
+```SQL
+CREATE TABLE [ IF NOT EXISTS ] table_name CLONE <source_object_name> [TIMESTAMP AS OF timestamp_expression]
+```
+
+* 可以使用 `TIMESTAMP AS OF timestamp_expression` 来克隆动态表在指定时间点的版本。只要该时间点在\*\*[数据保留周期](TIMETRAVEL.md)\*\*内（`data_retention_days`）。
+  * `timestamp_expression` 可以是以下任意一项：
+    * `'2024-10-18T22:15:12.013Z'`，即可以强制转换为时间戳的字符串
+    * `cast('2024-10-18 13:36:32 ' as timestamp)`
+    * `'2024-10-18'`，即日期字符串
+    * `current_timestamp() - interval 12 hours`
+    * `date_sub(current_date(), 1)`
+    * 本身就是时间戳或可强制转换为时间戳的任何其他表达式
+
+```
+CREATE TABLE normal_table_clone_version CLONE normal_table_base TIMESTAMP AS OF '2024-10-12 19:23:52.329';
+```
+
+## 动态表克隆
+
+```SQL
+CREATE DYNAMIC TABLE dt_name
+ [
+    refreshOption ::=
+    REFRESH [START WITH timestamp_expr] [interval_time] VCLUSTER vcname   
+ ]
+  CLONE <source_dynamic_table> [TIMESTAMP AS OF timestamp_expression]
+```
+
+* 克隆出的动态表默认暂停刷新，可以使用 `ALTER DYNAMIC TABLE table_name RESUME;` 来启动刷新任务。
+* `DYNAMIC TABLE dt_name`: 要创建的动态表的名称，`dt_name` 是一个占位符，您需要替换为实际的表名。
+* `REFRESH`：指定表的刷新选项。克隆动态表时可以指定刷新选项：
+  * 如果指定了刷新选项，则使用克隆表的刷新策略。
+  * 如果未指定刷新选项，则使用默认的刷新策略。
+* `START WITH timestamp_expr`: 可选子句，指定表开始刷新的时间点，`timestamp_expr` 是一个时间戳表达式。
+* `interval_time`: 指定刷新间隔的时间单位，这是一个 `INTERVAL` 类型，可以是以下任意一项：
+  * INTERVAL 1 year
+  * INTERVAL 2 month
+  * INTERVAL 3 day
+  * INTERVAL 4 hour
+  * INTERVAL 5 minute
+  * INTERVAL 30 second
+* `VCLUSTER vcname`: 指定计算集群的名称，`vcname` 是计算集群的实际名称。
+* `CLONE <source_dynamic_table>`: 从现有的动态表 `<source_dynamic_table>` 克隆。
+* `TIMESTAMP AS OF timestamp_expression`: 克隆动态表在指定时间点的版本，`timestamp_expression` 可以是多种时间戳表达式之一。只要该时间点在[数据保留周期](TIMETRAVEL.md)内（`data_retention_days`）。
+  * `timestamp_expression` 可以是以下任意一项：
+    * `'2024-10-18T22:15:12.013Z'`，即可以强制转换为时间戳的字符串
+    * `cast('2024-10-18 13:36:32 ' as timestamp)`
+    * `'2024-10-18'`，即日期字符串
+    * `current_timestamp() - interval 12 hours`
+    * `date_sub(current_date(), 1)`
+    * 本身就是时间戳或可强制转换为时间戳的任何其他表达式
+
+## 权限要求
+
+* 需要有当前 schema 下的 `CREATE TABLE` 权限来创建克隆表。
+* 需要有对原始表的 `SELECT` 权限。
+
+## 克隆表案例
+
+### 克隆普通表
+
+```SQL
+-- 创建普通表
+CREATE TABLE normal_table_base (id BIGINT, col STRING);
+
+-- 克隆普通表
+CREATE TABLE normal_table_clone CLONE normal_table_base;
+
+-- 指定基表的版本克隆
+CREATE TABLE normal_table_clone_version CLONE normal_table_base TIMESTAMP AS OF '2024-10-12 19:23:52.329';
+```
+
+### 克隆动态表
+
+```SQL
+-- 创建动态表
+CREATE DYNAMIC TABLE dt_table_base
+REFRESH INTERVAL 1 MINUTE
+VCLUSTER DEFAULT
+AS SELECT * FROM normal_table_base;
+
+-- 克隆动态表
+CREATE DYNAMIC TABLE dt_table_clone CLONE dt_table_base;
+
+-- 克隆时指定刷新间隔和计算集群
+CREATE DYNAMIC TABLE dt_table_clone_refresh
+REFRESH INTERVAL 2 MINUTE
+VCLUSTER DEFAULT
+CLONE dt_table_base;
+
+-- 克隆时指定动态表的版本
+CREATE DYNAMIC TABLE dt_table_clone_version
+CLONE dt_table_base TIMESTAMP AS OF '2024-10-12 20:25:32.247';

+# 分桶键（Clustered Key）和排序键（Sorted Key）
+
+在大数据存储与分析领域，数据的组织方式对查询性能和存储效率具有重要影响。本文将详细介绍分桶键（Clustered Key）和排序键（Sorted Key）的概念、使用方法以及实际应用示例，帮助您更好地优化数据组织结构。
+
+## 分桶键（Clustered Key）
+
+分桶键是表数据分布的核心。通过指定分桶键，Lakehouse会根据这些键对数据进行Hash运算，并将数据分散到不同的数据分桶（buckets）中。这种分散有助于避免数据倾斜和热点问题，同时提高并行处理能力。
+
+### 选择分桶键的准则
+
+- 选择取值范围广、重复值少的列作为分桶键，以实现数据的均匀分布。
+- 在进行`JOIN`操作时，如果连接的键与分桶键一致，可以显著提高性能。
+- 适用于数据量大的场景，推荐的数据分桶大小约为128MB到1GB，具体取决于数据的压缩率和访问模式。
+- 如果没有指定分桶键，则默认使用256个分桶。
+
+### 注意事项
+
+- 避免指定过小的分桶数量，以免产生大量小文件，影响元数据管理和I/O操作效率。
+- 过多的小文件会导致数据局部性差，增加任务调度开销，降低处理效率。
+
+## 排序键（Sorted Key）
+
+排序键用于指定数据文件内字段的排序方式。对于需要按特定字段排序或进行范围查询的场景，预先将数据按排序键组织可以大幅提高查询性能。
+
+### 使用排序键的注意事项
+
+- 可以为排序键指定升序（ASC）或降序（DESC）。
+- 虽然排序键可以提高查询性能，但在对大量数据进行插入时，维护排序顺序可能会消耗较多计算和I/O资源。
+
+## 实际应用示例
+
+### 示例1：创建表并指定分桶键与排序键
+
+```sql
+CREATE TABLE sales_data (
+    sale_id INT,
+    product_id INT,
+    quantity_sold INT,
+    sale_date DATE,
+    ...
+) CLUSTERED BY (product_id)
+SORTED BY (sale_date DESC)
+INTO 50 BUCKETS;
+```
+
+在这个示例中，创建了一个名为`sales_data`的表，数据将根据`product_id`列的哈希值被分散到50个分桶中。同时，分桶内的数据将按照`sale_date`列的降序进行排序。
+
+### 示例2：优化数据仓库的查询性能
+
+假设您正在处理一个包含大量交易记录的数据仓库，可以通过以下方式优化查询性能：
+
+```sql
+CREATE TABLE transaction_records (
+    transaction_id INT,
+    customer_id INT,
+    transaction_date DATE,
+    amount DECIMAL(10,2),
+    ...
+) CLUSTERED BY (customer_id)
+SORTED BY (transaction_date ASC)
+INTO 128 BUCKETS;
+```
+
+在这个示例中，`transaction_records`表根据`customer_id`进行分桶，分桶内的数据按照`transaction_date`进行排序。这样的设计有助于提高按客户查询交易记录的效率。
+
+## 结语
+
+合理使用分桶键和排序键，可以有效优化数据的物理存储结构，提高查询性能，尤其是在处理大规模数据集时。这种方法特别适用于数据仓库和大数据分析场景，可以显著提升数据处理的效率。希望本文能帮助您更好地理解和应用分桶键与排序键，从而优化您的数据组织方式。

+# 组合任务
+
+组合任务是一种特殊的任务类型，它支持将多个周期任务（例如离线同步、SQL 任务）封装为独立单元，以实现**统一调度配置、参数管理和运维操作**，并且能够与其他普通节点建立依赖关系。本任务类型适用于需要批量管理任务流程、统一控制调度周期的业务场景（如增量计算、跨任务协同）。组合任务与[任务组](task_group.md)功能进行对比，两者存在以下核心区别：
+* 任务组属于逻辑管理概念，可将多种任务置于一个组内进行统一展示与编排。组合任务是一种任务类型的实体，与普通的 SQL 任务处于同等地位，可在任务组中添加组合任务作为其元素之一。
+* 从外部看，组合任务是一个整体，但内部会包含一到多个子任务节点（这些子任务可以是 SQL 任务、离线同步任务等各种周期调度任务）。
+* 组合任务支持统一设定调度时间，其内部所有子任务节点依据该调度时间进行同频调度。这尤其适用于对所有任务节点的数据新鲜度有相同要求的数据处理链路。任务组上不支持设定调度定时属性。
+
+## 快速上手：创建组合任务
+
+组合任务的创建操作，整体上和普通周期 SQL 任务等非常类似。
+
+### 创建入口
+
+支持通过以下路径新建组合任务：
+
+* 任务开发：任务Tab → 新建任务 → 选择“组合任务”
+
+  ![](.topwrite/assets/image_1752130018729.png =420)
+
+* 任务组详情页：任务组内 → 添加新任务 → 选择“组合任务”；
+  
+  ![](.topwrite/assets/image_1752130033606.png =680)
+
+* 工作区：顶部导航栏 → 新建任务 → 选择“组合任务”。
+  
+  ![](.topwrite/assets/image_1752130048252.png =680)
+
+### 基础信息填写
+
+在创建组合任务的弹框中，和其他普通 SQL 任务一样，填写需要的信息：
+
+* 任务名称：必填。
+* 文件夹：任务要放入的文件夹（必填）。
+* 任务组：选择是否放入任务组，如需放入则选定具体的任务组名称（可选）。
+
+  ![](.topwrite/assets/image_1752130064673.png =680)
+
+## 核心功能操作指南
+
+### 子任务管理（画布模式）
+
+组合任务目前通过**画布**（DAG 图）来展示子任务节点，并支持以下操作：
+![](.topwrite/assets/image_1752130101512.png =680)
+
+#### 添加子任务
+
+* **入口**：画布工具栏 → 「新建子任务」→ 选择任务类型（仅支持周期任务：离线同步、SQL等；**不支持实时任务**）。通过单击任务类型或拖拽的方式，可将子任务添加到组合任务中。
+
+  ![](.topwrite/assets/image_1752130110716.png =360)
+
+* **默认状态**：新增的子任务，默认无依赖，需手动调整依赖关系（通过页面上连线或在子任务详情进行配置）。
+
+#### 编辑子任务
+
+* **方式**：
+  * 在添加子任务节点时，会默认进入子任务的详情页，便于编写代码和配置调度信息。
+  * 双击子任务 → 进入普通节点编辑页（复用现有编辑功能）；
+
+* **限制**：为了确保组合任务提交后运行正常，子任务不支持独立保存为半成品，需填写所有必填属性（如代码、集群、调度属性）后才能保存。在退出子任务编辑前，请确保这些信息完整且已正确保存。
+
+#### 依赖编排
+
+* **子任务中配置**：在子任务上，点击「调度」→ 在「调度依赖」中设定它依赖的上游子任务。
+* **画布上连线**：在组合任务的DAG画布上，选中源节点 → 拖拽连线至目标节点 → 建立“上游→下游”依赖。也可以通过操作连线来删除依赖关系。
+
+#### 画布工具
+
+* **自动排版**：工具栏 → 「自动布局」→ 按依赖关系优化DAG展示；
+* **缩放/刷新**：工具栏 → 「+/-」调整画布大小，或「刷新」重置视图。
+
+### 调度配置（全局与局部结合）
+
+组合任务的调度策略通过**全局配置**（组合任务层级）与**局部配置**（子任务层级）协同管理。整体思路是：子任务默认继承组合任务的全局配置，也支持在局部单独配置；若局部已配置，则以局部配置为准。关键配置项如下表：
+
+| 配置项   | 全局配置（组合任务）              | 局部配置（子任务）                    |
+| ----- | ----------------------- | ---------------------------- |
+| 调度时间  | 必配，支持Cron表达式（子任务不可独立设置） | 无（子任务遵循组合任务全局设定的调度时间、同频调度运行） |
+| 实例重跑  | 全局设置（重跑次数、间隔），子任务默认继承   | 可选覆盖全局设置（仅支持SQL等特定任务类型）      |
+| 任务优先级 | 全局设置（默认值）               | 可选单独设置（覆盖全局，仅SQL节点支持）        |
+| 自依赖   | 全局设置（控制组合任务周期依赖）        | 无（子任务自依赖通过组合任务全局自依赖间接实现）     |
+
+**示例**：若组合任务全局设置为“重跑次数 3 次，间隔 5 分钟”，某子任务单独配置为“重跑次数 5 次”，则该子任务实际使用“重跑 5 次，间隔 5 分钟”。
+
+![](.topwrite/assets/image_1752130126629.png =680)
+
+![](.topwrite/assets/image_1752130133390.png =680)
+
+### 参数管理（组合任务→子任务传递）
+
+#### 定义参数
+
+* **入口**：组合任务详情页 → 点击「参数」→ 在弹框中新增参数（如`composite_task_param`）：
+
+  ![](.topwrite/assets/image_1752130143435.png =680)
+
+  ![](.topwrite/assets/image_1752130151838.png =680)
+
+* **作用域**：仅当前组合任务内部有效，不同组合任务之间参数隔离。
+
+#### 引用参数
+
+在子任务的参数配置中，若参数名称与组合任务定义的参数名称相同，在参数取值处会自动识别并提示选择参数的取值来源。若要使用组合任务全局定义的参数，在取值来源处选择“组合任务”；否则，可选择“任务”。
+
+![](.topwrite/assets/image_1752130161305.png =680)
+
+在子任务的代码中，支持通过`${参数名}`引用参数。**示例**（SQL子任务）：
+
+```
+SELECT * FROM user_log WHERE dt = '${composite_task_param}'  
+```
+
+## 高级操作：保存与提交
+
+### 保存组合任务
+
+* 组合任务当前不支持全局统一保存所有子任务节点。请逐一保存每个子任务，确保其代码、调度配置等信息已保存。之后，再提交组合任务。
+
+### 提交组合任务
+
+* **作用**：支持将组合任务及内部所有子任务提交到生产环境周期调度运行，会生成对应的“提交版本”。
+
+* **操作入口**：组合任务详情页 → 「提交」。
+
+  ![](.topwrite/assets/image_1752130174992.png =680)
+
+## 运维与监控
+
+### 组合任务的运维
+
+组合任务在运维中心会与其他周期任务一并在列表中展示，并支持类似的操作，如暂停、补数据、下线等。
+
+![](.topwrite/assets/image_1752130184652.png =680)
+
+| 操作     | 说明                                                                 |
+| ------ | ------------------------------------------------------------------ |
+| 暂停/恢复 | 暂停后，组合任务及子任务停止调度；恢复后，按当前配置继续执行。                             |
+| 补数据    | 选择时间范围 → 组合任务整体按调度规则生成补数据实例（包含所有子任务实例）。                        |
+| 下线     | 下线后任务不再调度。需检查是否存在下游依赖（若存在下游依赖，则无法直接下线，需使用“下线（含下游）”功能）。 |
+
+### 组合任务实例的运维
+
+在实例运维 Tab 页，可以查看到组合任务的实例，与其他周期任务实例并列，并支持重跑、置成功/置失败等操作，如下图所示：
+
+![](.topwrite/assets/image_1752130199325.png =680)

+* **整体状态**：组合任务实例状态由子任务状态综合判定，具备以下状态：未运行（所有子任务未运行）、运行中（任一子任务运行中）、运行成功（所有子任务成功）、运行失败（至少一个子任务失败）。
+* **下钻查看**：点击实例ID → 进入子任务实例DAG页，查看各子任务运行详情（含日志、状态）。
+
+#### 实例操作
+
+| 操作        | 在哪些状态下支持       | 行为说明                                                                 |
+| --------- | -------------- | ---------------------------------------------------------------------- |
+| 重跑        | 任意终态（失败/成功）    | 整体重跑组合任务，子任务按各自重跑规则生成新实例（不支持选择部分子任务）。                                 |
+| 置成功/置失败 | 未运行/终态         | 组合任务及所有子任务实例状态强制变更为成功/失败。                                            |
+| 终止        | 运行中            | 终止所有运行中/未运行的子任务实例，状态置为失败。                                              |
+
+### 组合任务的监控告警
+
+在监控告警中，组合任务会被归入周期调度任务这一大类。先前的“任务实例运行失败”、“周期任务实例完成时间”等监控项，对其也同样生效。可以像配置普通SQL周期任务一样，配置监控规则来对其运行状态和耗时等进行监控。
+

+
+### 组合任务触发质量规则校验
+
+在配置数据质量规则时，于规则运行触发方式中，可选择组合任务作为调度触发对象，如下图所示。可以选择具体的子任务来触发；若“子任务”留空，则会在组合任务整体运行完成后触发。
+
+![](.topwrite/assets/image_1752131279717.png =680)
+
+## 注意事项
+
+1. **类型限制**：组合任务的子任务，仅支持周期任务（离线同步、SQL等），实时任务（多表实时同步、Continuous Job等）不可添加。
+2. **参数作用域**：组合任务参数仅内部可见，不能被其他组合任务使用。跨组合任务共享参数，需通过任务组参数等来承接。
+3. **版本管理**：组合任务仅支持“提交版本”（无保存版本），暂不支持版本回滚。
+4. **任务依赖**：在任务组内，组合任务作为整体存在，不可单独添加任务组内部的子任务，且依赖关系为组合任务整体与其他任务的依赖。组合任务的内部子任务不能依赖任务组内其他任务，也不能被任务组内其他任务依赖。

+# 将数据导入云器 Lakehouse 的完整指南
+
+## 数据入湖：通过数据库客户端 DBV/SQLWorkbench PUT 文件的方式
+
+#### 概述
+
+PUT 命令是 Lakehouse SQL 中的一个实用工具，用于将客户端主机的本地文件上传到 Lakehouse 的数据湖 Volume 对象中。通过该命令，用户可以轻松地将本地文件传输至云端，实现数据的快速迁移和同步。要执行 PUT 命令，您可以使用 sqlline 工具或数据库管理工具。
+
+#### 使用场景
+
+* 将本地文件上传到数据湖 Volume 对象。
+* 快速迁移和同步本地与云端数据。
+
+#### 实现步骤
+
+##### 下载安装 DBV
+
+本指南示例数据库管理工具使用 [DbVisualizer Free版](https://www.dbvis.com/)。如已安装请跳过。
+
+下载云器 Lakehouse 的 [JDBC Driver](JDBC-Driver.md) 到本地。
+
+在 DBV 中安装 Lakehouse 的 JDBC Driver。
+
+##### 在 DBV 中新建 Database
+
+建立与云器 Lakehouse 的连接。
+
+##### 新建 SQL Script 并运行
+
+```SQL
+PUT 'data/lift_tickets_data.csv.zip' TO volume ingest_demo  FILE 'gz/lift_tickets_data_put.csv.zip';SHOW  VOLUME DIRECTORY ingest_demo;
+```
+
+##### ![](.topwrite/assets/image_1736215162253.png =531)

+# 将数据导入云器Lakehouse的完整指南
+
+## Python环境设置
+
+本指南有一个数据生成器和几个示例，需要 Python 3.8、Java 和一些其他库和实用程序。
+
+为了设置这些依赖项，我们将使用 conda。
+
+创建一个名为[ environment.yml ](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/config/environment.yml)的文件，内容如下：
+
+```
+name: cz-ingest-examples
+channels:
+  - main
+  - conda-forge
+  - defaults
+dependencies:
+  - faker=28.4.1
+  - kafka-python=2.0.2
+  - maven=3.9.6
+  - openjdk=11.0.13
+  - pandas=1.5.3
+  - pip=23.0.1
+  - pyarrow=10.0.1
+  - python=3.8.20
+  - python-confluent-kafka
+  - python-dotenv=0.21.0
+  - python-rapidjson=1.5
+  - psycopg2
+  - pip:
+      - optional-faker==2.1.0
+      - clickzetta-connector-python
+      - clickzetta-zettapark-python
+```
+
+要创建所需的环境，请在 shell 中运行以下命令：
+
+```Bash
+conda env create -f environment.yml
+conda activate cz-ingest-examples
+```
+
+任何时候您想返回本指南，都可以通过在 shell 中运行以下命令重新激活此环境：
+
+```Bash
+conda activate cz-ingest-examples
+```
+
+## 测试数据生成
+
+本指南会为滑雪胜地的顾客生成虚构的缆车票等数据。
+
+您也许有自己想生成的数据，可随意修改数据生成器、表格和代码，让其更符合您的用例。
+
+本指南中介绍的大多数摄取方式都会用到数据，所以最好运行一次数据生成，然后在不同的摄取模式中重复使用生成的数据。
+
+在您的电脑上通过VS Code为这个项目创建一个目录，再添加一个叫 data\_generator.py 的文件。这个代码会以要创建的票数为参数，输出每行一张缆车票（记录）的 json 数据。本指南里的其他文件可以放在同一个目录中。
+
+你也可以直接[下载本文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/data_generator.py)。

+
+您应该看到 1 条记录输出，会有两种格式的文件输出：CSV和JSON格式。
+
+为了能够快速为指南的其余部分提供数据，请将数据存储到文件中以供重复使用。
+
+在你的 shell 中运行以下命令：
+
+```Bash
+python ./data_generator.py 100000
+```
+
+您可以将记录的大小增加或减少到您想要的任何数字。这会将示例数据输出到您当前的目录，此文件将在后续步骤中使用，因此请记下您存储此数据的位置并在需要时稍后替换。
+
+您也可以在[这里直接访问或者下载](https://github.com/yunqiqiliang/clickzetta_quickstart/tree/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/datahttps://github.com/yunqiqiliang/clickzetta_quickstart/tree/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/data) 通过“python ./data\_generator.py 100000”命令生成的文件。
+
+## Postgres和Kafka环境设置
+
+本指南使用Postgres作为数据库数据源。你可以使用已有的Postgres数据库。主要后续的数据库网络地址、数据库名称、Schema名称、用户名密码等保持一致即可。
+
+### 启动数据库实例
+
+在开始此步骤之前，请确保已为[Mac](https://docs.docker.com/desktop/install/mac-install/)、[Windows](https://docs.docker.com/desktop/install/windows-install/)或[Linux](https://docs.docker.com/desktop/install/linux/)安装了 Docker Desktop 。确保您的机器上已安装[Docker Compose 。](https://docs.docker.com/compose/install/)
+
+1. 要使用 Docker 启动 PostgreSQL 数据库，您需要创建一个名为docker-compose.yaml的文件。此文件将包含 PostgreSQL 数据库的配置。如果您有另一个容器客户端，请启动容器并使用下面的 PostgreSQL 映像。
+2. 打开您选择的 IDE（比如VS Code），通过复制并粘贴以下内容来复制并粘贴此文件（你也可以直接[下载本文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/data_generator.pyhttps://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/config/docker-compose.yaml)。）：
+
+```YAML
+services:
+  postgres:
+    image: "postgres:17"
+    container_name: "postgres17"
+    environment:
+      POSTGRES_DB: 'postgres'
+      POSTGRES_USER: 'postgres'
+      POSTGRES_PASSWORD: 'postgres'
+    ports:
+      - "5432:5432"
+    command:
+      - "postgres"
+      - "-c"
+      - "wal_level=logical"
+    volumes:
+      - ./postgres-data:/var/lib/postgresql/data
+  kafka:
+    image: 'bitnami/kafka:latest'
+    container_name: kafka
+    ports:
+      - "9093:9093"
+    expose:
+      - "9093"
+    environment:
+      - KAFKA_CREATE_TOPICS="clickzettalakehouserealtimeingest:1:1"
+      - KAFKA_CFG_AUTO_CREATE_TOPICS_ENABLE=true
+      - KAFKA_CFG_NODE_ID=0
+      - KAFKA_CFG_PROCESS_ROLES=controller,broker
+      - KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CLIENT:PLAINTEXT,EXTERNAL:PLAINTEXT,CONTROLLER:PLAINTEXT
+      - KAFKA_CFG_LISTENERS=CLIENT://:9092,EXTERNAL://:9093,CONTROLLER://:9094
+      - KAFKA_CFG_ADVERTISED_LISTENERS=CLIENT://kafka:9092,EXTERNAL://localhost:9093
+      - KAFKA_INTER_BROKER_LISTENER_NAME=CLIENT
+      - ALLOW_PLAINTEXT_LISTENER=yes
+      - KAFKA_CFG_CONTROLLER_QUORUM_VOTERS=0@localhost:9094
+      - KAFKA_CFG_CONTROLLER_LISTENER_NAMES=CONTROLLER
+    volumes:
+      - ./bitnami/kafka:/bitnami/kafka
+```
+
+3. 打开终端并导航到docker-compose.yaml文件所在的目录。运行以下命令启动 PostgreSQL 数据库：
+
+```Shell
+docker-compose up -d
+```
+
+### 创建Kafka Topic
+
+进入 Kafka 容器：
+
+bash
+
+```
+docker exec -it kafka /bin/bash
+```
+
+手动创建主题：
+
+bash
+
+```
+kafka-topics.sh --create --topic clickzetta_lakehouse_realtime_ingest --bootstrap-server localhost:9092 --partitions 1 --replication-factor 1
+```
+
+然后再次列出主题以确认创建是否成功：
+
+bash
+
+```
+kafka-topics.sh --list --bootstrap-server localhost:9092
+```
+
+如果主题成功创建，你应该会看到 `clickzetta_lakehouse_realtime_ingest` 列表中的主题。
+
+### 连接数据库
+
+要使用 Visual Studio Code 或 DBV/DBGrid/PyCharm 或您选择用于数据库连接的任何 IDE 连接到预配置的数据库，请使用提供的凭据执行以下步骤：
+
+1. 打开您选择的工具以连接 PostgreSQL 数据库
+
+   1. 对于 VSCode，你可以使用[PostgreSQL 扩展](https://marketplace.visualstudio.com/items?itemName=cweijan.vscode-postgresql-client2)
+   2. 对于 PyCharm，您可以使用[数据库工具和 SQL 插件](https://www.jetbrains.com/help/pycharm/database-tool-window.html)
+
+2. 单击`+`符号或类似符号以添加数据源
+
+3. 使用这些连接参数：
+
+   1. 用户：`postgres`
+   2. 密码：`postgres`
+   3. 数据库：`postgres`
+   4. 网址：`jdbc:postgresql://localhost:5432/`
+
+4. 测试连接并保存
+
+5. 为了能让云器Lakehouse Studio通过公网能够访问到Postgres数据库，务必给Posrgres数据库做公网NAT映射。
+
+### 加载数据
+
+1. 在 PostgreSQL 中运行以下postgres脚本来创建模式和表(你也可以直接[下载本文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/posgtres_ddl.sql)。）：
+
+```SQL

+-- 删除事件报告数据表
+DROP TABLE IF EXISTS incident_reports CASCADE;
+
+-- 删除天气数据表
+DROP TABLE IF EXISTS weather_data CASCADE;
+
+-- 删除住宿数据表
+DROP TABLE IF EXISTS accommodation_data CASCADE;
+
+-- 滑雪票数据表
+CREATE TABLE lift_tickets_data (

+
+```
+
+2. 将以下代码Copy进Python文件然后运行
+3. 在电脑上打开VS Code，创建一个名为 import\_csv\_into\_pg.py 的文件，并将以下代码复制到import\_csv\_into\_pg.py文件中。lift\_tickets\_data.csv文件为在“测试数据生成”步骤生成的gz文件解压后的文件。(你也可以直接[下载本文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/import_csv_into_pg.py)。）
+
+```Python
+import psycopg2
+import os
+def load_csv_to_postgres(csv_file, table_name):
+    with open(csv_file, 'r') as f:
+        cur.copy_expert(f"COPY {table_name} FROM STDIN WITH CSV HEADER DELIMITER ','", f)
+    conn.commit()
+# 数据库连接信息
+conn = psycopg2.connect(
+    dbname="postgres",
+    user="postgres",
+    password="postgres",
+    host="localhost",
+    port="5432"
+)
+cur = conn.cursor()
+# 设置 search_path 
+cur.execute("SET search_path TO ingest_demo;")
+
+# Clear all data from the lift_tickets_data table 
+# cur.execute("TRUNCATE lift_tickets_data;")
+
+
+# 定义CSV文件所在目录
+csv_directory = 'data'
+
+# 按表的依赖关系排列的CSV文件列表
+csv_files = [
+    "lift_tickets_data.csv",         # 首先导入被依赖的表
+    "weather_data.csv",
+    "lift_usage_data.csv",
+    "feedback_data.csv",
+    "incident_reports.csv",
+    "accommodation_data.csv"
+]
+
+# 遍历文件列表并加载到对应的表中
+for filename in csv_files:
+    csv_file = os.path.join(csv_directory, filename)
+    table_name = os.path.splitext(filename)[0]  # 文件名去掉扩展名作为表名
+    print(f"Loading {csv_file} into table {table_name}...")
+    load_csv_to_postgres(csv_file, table_name)
+    print(f"Loaded {csv_file} into table {table_name} successfully!")
+
+# Execute the SELECT query to count the rows in the table 
+cur.execute("SELECT count(*) FROM lift_tickets_data;")
+count = cur.fetchone()[0] 
+# Print the result 
+print(f"Total number of records in lift_tickets_data: {count}")
+# 关闭游标和连接
+cur.close()
+conn.close()
+```
+
+在VS Code里新建一个“终端”，并运行如下命令激活在“环境设置”步骤创建的Python环境。如果已在cz-ingest-examples环境里，请跳过。
+
+```Shell
+conda activate cz-ingest-examples
+```
+
+然后在同一终端里运行如下命令：
+
+```Shell
+python import_csv_into_pg.py
+```
+
+输出显示如下，则表示数据导入成功：
+
+```Markdown
+Total number of records in lift_tickets_data: 100000
+```

+# 将数据导入云器Lakehouse的完整指南
+
+## 数据入仓：通过JavaSDK批量和实时加载数据
+
+#### 概述
+
+云器Lakehouse提供了[JAVA SDK](java_reference/java-sdk-summary.md)，可在流行的IDE（如VS Code）中通过Java和SQL编程的方式，将数据加载到云器Lakehouse的表里。
+
+#### 使用场景
+
+这种方式可以方便地批量加载数据，适合在Java编程环境中进行大量数据的批量导入和实时写入，因为云器Lakehouse针对大批量数据写入进行了更多优化。
+
+#### 实现步骤
+
+##### 下载代码
+
+从[Github仓库里](https://github.com/yunqiqiliang/clickzetta_quickstart/tree/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta)下载本指南的代码到本地（如果已下载请忽略）。
+
+将项目目录添加到VS Code的工作区中。
+
+:-: ![](.topwrite/assets/image_1736229919125.png =512)
+
+##### 修改参数
+
+将 config/config-ingest-sample.json 文件名改为 config/config-ingest.json，并修改 config-ingest.json 中的各个[参数值](https://uat-doc.clickzetta.com/JDBC-Driver)。
+
+```JSON
+{
+  "username": "请输入您的用户名",
+  "password": "请输入您的密码",
+  "service": "请输入您的服务地址，例如 region_id.api.clickzetta.com",
+  "instance": "请输入您的实例 ID",
+  "workspace": "请输入您的工作空间，例如 gharchive",
+  "schema": "请输入您的模式，例如 public",
+  "vcluster": "请输入您的虚拟集群，例如 default_ap",
+  "sdk_job_timeout": 10,
+  "hints": {
+    "sdk.job.timeout": 3,
+    "query_tag": "a_comprehensive_guide_to_ingesting_data_into_clickzetta"
+  }
+}
+```

+# 将数据导入云器 Lakehouse 的完整指南
+
+## 数据入仓：使用Lakehouse Studio实时同步导入Kafka数据
+
+#### 概述
+
+#### 使用场景
+
+已有 Kafka 数据源，对数据同步的实时性要求高，期望能实时同步到 Lakehouse 的表中，实现端到端秒级延迟。
+
+#### 实现步骤
+
+导航到 开发 -> 任务，点击“+”，选择“实时同步”，新建一个“实时同步”作业。
+
+:-: ![](.topwrite/assets/image_1736319394961.png =740)
+
+主要配置如下：
+
+:-: ![](.topwrite/assets/image_1736319702232.png =740)
+
+^
+
+在左侧选择源端 Kafka 数据源时，请配置正确的 `mode`、`groupId` 和 `codec`。其中请特别注意，`groupId` 尽量不要在多个实时同步任务中复用，以避免相互干扰、同时消费数据导致目标数据丢失或不完整的情况。
+
+^
+
+然后在右侧选择Lakehouse目标端，选择已有的数据表，或者新建数据表（推荐使用）：target\_table\_from\_kafka。
+
+在“新建数据表”SQL代码里，将表名改为“target\_table\_from\_kafka”。
+
+:-: ![](.topwrite/assets/image_1736321482644.png =740)
+
+^
+
+在“字段映射配置”区域，系统会默认使用 Kafka Topic 的内置字段进行数据字段映射。如果 Topic 内的消息格式为 JSON，您还可以通过新增计算列的方式，使用 JSONPath 规则解析 `value` 字段中的内容。例如，通过下图所示的 `[__value__].[accountId]` 来提取源端 Topic 中 `__value__` 字段内的 `accountId`，并写入到目标端的 `__value__` 字段中。
+
+:-: ![](.topwrite/assets/image_1736322127793.png =740)
+
+^
+
+在“同步规则配置”中，设定同步的最大并发数。增大并发数可以提升数据消费速度。
+
+^
+
+检查字段映射符合预期后，在配置中设定“集群”等必填信息，点击“确定”，然后点击“保存”以保存任务配置。
+
+:-: ![](.topwrite/assets/image_1736322224165.png =740)
+
+实时同步任务当前不支持直接运行测试，需要提交发布后，检查运行结果是否正常。
+
+:-: ![](.topwrite/assets/image_1736322037109.png =740)
+
+#### 下一步建议
+
+* 在运维中心启动实时同步任务，观察任务运行指标并验证数据同步结果是否正常。
+
+  :-: ![](.topwrite/assets/image_1736322337162.png =740)
+
+* 第一次启动时选择“无状态启动”的方式即可。
+
+  :-: ![](.topwrite/assets/image_1736322414065.png =740)
+
+* 正常启动后，可以看到以下监控指标，表示同步任务运行正常。
+
+  :-: ![](.topwrite/assets/image_1736322603085.png =740)
+
+* 抽查目标表中的数据，与源端数据进行校验核对，确认是否符合预期。

+# 将数据导入云器Lakehouse的完整指南
+
+## 数据入仓：通过云器Lakehouse Studio 加载本地文件
+
+#### 概述
+
+您将使用[云器Lakehouse Studio](https://accounts.clickzetta.com/)来基于WEB界面操作、以无代码的方式来加载本地数据到云器Lakehouse的表中。
+
+#### 使用场景
+
+适合较小（不大于2GB）的本地文件（CSV、TXT、Parquet、AVRO、ORC）直接上传到云器Lakehouse的表中，无需编程实现，实现方式最简单。
+
+#### 实现步骤
+
+##### 上传文件
+
+导航到数据->数据目录，单击“上传数据”，导入本地文件（测试数据生成章节生成的CSV文件）到表中。
+
+:-: ![](.topwrite/assets/image_1736146842294.png =519)
+
+##### 导入数据
+
+点击“上传数据”：
+
+* 测试数据生成章节生成的测试数据
+* 云器Lakehouse设置章节创建的Schema
+* 选择新建表，表名为：lift\_tuckets\_import\_by\_studio\_web
+* 云器Lakehouse设置章节创建的虚拟计算集群
+
+:-: ![](.topwrite/assets/image_1736146857816.png =513)
+
+点击“下一步”后，检查上传数据自动设置项是否正确，如果数据预览符合预期，则自动设置正确，点击“确认”即可完成数据上传。
+
+:-: ![](.topwrite/assets/image_1736146867287.png =516)
+
+##### 结果校验
+
+进入“数据”查看导入状态和数据：
+
+可以看到导入数据的结果里，写入行数为“100,000”，这个在“测试数据生成”步骤生成的数量一致。
+
+:-: ![](.topwrite/assets/image_1736146881028.png =523)
+
+可以进一步“预览数据”，确认数据加载成功：
+
+:-: ![](.topwrite/assets/image_1736146888569.png =518)
+
+至此，我们通过云器Lakehouse Studio 加载本地文件到表中。
+
+:-: ![](.topwrite/assets/image_1736146899159.png =515)
+
+#### 下一步建议
+
+* 继续加载数据到同一张表中或者其它表中。通过在上个页面的“上传”，可以上传更多数据到同一张表中。
+* 通过云器Lakehouse自带的DataGPT进行可视化数据探索、以问答方式进行数据分析。
+* 在云器Lakehouse Studio的IDE里开发SQL任务，进一步清洗和转换数据，分析数据。

+# 将数据导入云器Lakehouse的完整指南
+
+## 数据入仓：通过云器Lakehouse Studio 批量加载（公网连接）
+
+#### 概述
+
+#### 使用场景
+
+已有数据源（包括数据库、数据仓库）具备公网可访问的地址（比如做了公网NAT映射），单表数据量大，且要求同步成本低，对数据新鲜度要求低（往往是小时级别甚至天级别）的情况下，将数据从数据源的表同步到Lakehouse的表中。
+
+#### 实现步骤
+
+导航到开发->任务，点击“+”，选择“离线同步”，新建一个“离线同步”作业。
+
+:-: ![](.topwrite/assets/image_1736147655855.png =464)
+
+其它参数配置如下：
+
+:-: ![](.topwrite/assets/image_1736147664609.png =470)
+
+然后选择新建数据表：lift_tickets_data_from_pg_batch。
+
+在"新建数据表"SQL代码里，将表名改为"lift_tickets_data_from_pg_batch"。
+
+:-: ![](.topwrite/assets/image_1736147671728.png =455)
+
+检查字段映射是否符合预期，然后测试运行同步任务：
+
+:-: ![](.topwrite/assets/image_1736147681157.png =459)
+
+检查测试结果：
+
+查看测试任务的日志，检查numWrite的数量和源表的数据行数一致。
+
+:-: ![](.topwrite/assets/image_1736147689681.png =469)
+
+#### 下一步建议
+
+* 配置where条件，设置每次运行需要同步的数据，而不是全量。一般是基于时间字段的过滤。
+
+* 配置调度参数并提交、运维，周期性同步数据。
+
+  * 如果是适合数据量小的维表数据，则无需设置where条件，将数据写入模式设置为"覆盖写入"，每次都进行全量覆盖。
+  * 如果是数据量大的事实表数据，需要设置where条件，将数据写入模式设置为“追加写入”，每次都进行增量追加写入，以降低每次的同步数据量和同步成本。避免每次都全量同步带来的高成本。
+
+* 离线同步任务作为数据ELT的数据抽取（E）和加载（L）的开始，可以进一步通过SQL任务对加载进数仓的数据进行清洗和转化（T）。

+
+任务名：05\_通过Studio内置的Python节点从web加载文件入湖。
+
+:-: ![](.topwrite/assets/image_1736148972084.png =427)
+
+##### 开发Python任务代码
+
+将[如下代码](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/py_data_to_datalake_from_web_by_python_node.py)粘贴到新建Python任务的代码编辑器里：
+
+```Python
+import os,io
+import subprocess
+from datetime import datetime, timedelta
+import oss2
+
+# 阿里云OSS配置
+ACCESS_KEY_ID = '${ak}'
+ACCESS_KEY_SECRET = '${sk}'
+BUCKET_NAME = '你的bucketname'
+ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com'
+ROOT_PATH = f'{BUCKET_NAME}/ingest_demo/from_web'
+
+try:
+    # 构建wget命令
+    url = f"https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/data/lift_tickets_data.csv.gz"

+    wget_output = subprocess.check_output(cmd)
+    print(f"Wget file done...")
+
+    # 将输出转换为内存中的文件对象
+    file_obj = io.BytesIO(wget_output)
+except Exception as e:
+    print(f"An error occurred: {e}")
+    file_obj = None
+    raise
+
+if file_obj:
+    try:
+        # 初始化阿里云OSS
+        auth = oss2.Auth(ACCESS_KEY_ID, ACCESS_KEY_SECRET)
+        bucket = oss2.Bucket(auth, ENDPOINT, BUCKET_NAME)
+
+        # 上传文件到OSS
+        oss_path = f"{ROOT_PATH}/lift_tickets_data.csv.gz"
+        print(f"osspath: {oss_path}")
+        bucket.put_object(oss_path, file_obj)
+        print(f"Put file to oss done...")
+    except Exception as e:
+        print(f"An error occurred: {e}")
+    finally:
+        # 关闭内存中的文件对象
+        file_obj.close()
+```
+
+##### 给任务配置参数
+
+其中有两个参数：
+
+ACCESS\_KEY\_ID = '${ak}'ACCESS\_KEY\_SECRET = '${sk}'
+

+
+:-: ![](.topwrite/assets/image_1736148983636.png =435)
+
+点击“加载代码中的参数”，并为参数填写对应的值：
+
+:-: ![](.topwrite/assets/image_1736148989712.png =431)
+
+##### 运行测试
+
+点击“运行”，执行Python代码。
+
+:-: ![](.topwrite/assets/image_1736148997078.png =427)
+
+##### 检查上传结果
+
+登录阿里云对象存储，查看上传的文件。
+
+:-: ![](.topwrite/assets/image_1736149004171.png =415)
+
+#### 下一步建议

+
+#### 下一步建议
+
+在数据源中插入新数据，查看增量同步的结果。
+
+“停止”该同步任务。运行该任务的虚拟计算集群设置了自动停止，会在作业停止后的设定时间（秒数）内停止运行，从而节省费用，实现按需运行。

+# 将数据导入云器 Lakehouse 的完整指南
+
+## 数据入仓：通过云器 Lakehouse Studio 以 SQL INSERT 方式导入数据
+
+#### 概述
+
+在云器 Lakehouse 平台中，用户可以使用 `INSERT` 语句将数据导入目标表。该语句支持多种导入方式，包括直接插入值、从其他表查询导入数据以及从外部文件导入数据。以下文档将详细介绍如何使用 `INSERT` 语句导入数据，以及其使用场景、操作示例和注意事项。
+
+#### 方式一：使用`INSERT INTO VALUES`语句导入数据
+
+##### 使用场景
+
+适用于手动导入少量数据，用于调试与测试。对于大规模数据处理，通常建议采用批量插入、流式数据导入等更加高效的方法来确保数据导入过程的稳定性和性能。
+
+##### 实现步骤
+
+导航到 开发 -> 任务，单击 “+” 新建一个 SQL 任务（以下两种方式都在同一个任务里实现）。
+
+![](.topwrite/assets/image_1736148597217.png =470)
+
+您可以使用 `INSERT INTO VALUES` 语句直接插入数据。多个记录之间使用逗号分隔。
+
+```SQL
+--方式一：使用INSERT INTO SELECT FROM TABLE语句插入
+DROP TABLE IF EXISTS ingest.lift_tuckets_import_by_insert_into_values;
+CREATE TABLE IF NOT EXISTS ingest.lift_tuckets_import_by_insert_into_values(
+  `txid` string,
+  `rfid` string,
+  `resort` string,
+  `purchase_time` timestamp_ltz,
+  `expiration_time` date,
+  `days` int,
+  `name` string,
+  `address_street` string,
+  `address_city` string,
+  `address_state` string,
+  `address_postalcode` string,
+  `phone` string,
+  `email` string,
+  `emergency_contact_name` string,
+  `emergency_contact_phone` string);
+
+INSERT INTO ingest.lift_tuckets_import_by_insert_into_values (
+  txid, rfid, resort, purchase_time, expiration_time, days, name, address_street, 
+  address_city, address_state, address_postalcode, phone, email, emergency_contact_name, emergency_contact_phone
+) VALUES
+('0056b1f3-79b0-455c-80e9-3b80c45ac61e', '0x39eb22cbb32e9e115917b6', '长安壹号',
+  timestamp_ltz '2023-08-30 12:00:00', TO_DATE('2025-03-12', 'yyyy-MM-dd'), 2, '佘雪梅', '广州路S座', 
+  '艳市', '河北省', 853592, 13912709719, 'pchen@example.net', '林楠', 18041629236),
+('52016065-1399-48cc-aed2-d4a525d90452', '0x121a00c15e41d8c3410c7490', '海底捞',
+  timestamp_ltz '2023-08-30 12:00:00', TO_DATE('2025-10-16', 'yyyy-MM-dd'), 3, '韦超', '上海路R座', 
+  '伟县', '香港特别行政区', 123342, 18259131600, 'panyan@example.net', '魏玉兰', 14795983190);
+```
+
+#### 方式二：使用`INSERT INTO SELECT`语句导入数据
+
+##### 使用场景
+
+如果需要从另一个表中导入数据，可以使用 `INSERT INTO SELECT` 语句。您可以选择导入整个表的数据，也可以进行 ETL 操作，如选择部分列或进行数据转换。
+
+##### 实现步骤
+
+导航到 开发 -> 任务，单击 “+” 新建一个 SQL 任务。
+
+```SQL
+--方式二：使用INSERT INTO SELECT FROM TABLE语句插入
+DROP TABLE IF EXISTS ingest.lift_tuckets_import_by_insert_into_select;
+CREATE TABLE IF NOT EXISTS ingest.lift_tuckets_import_by_insert_into_select(
+  `txid` string,
+  `rfid` string,
+  `resort` string,
+  `purchase_time` timestamp_ltz,
+  `expiration_time` date,
+  `days` int,
+  `name` string,
+  `address_street` string,
+  `address_city` string,
+  `address_state` string,
+  `address_postalcode` string,
+  `phone` string,
+  `email` string,
+  `emergency_contact_name` string,
+  `emergency_contact_phone` string);
+  
+INSERT INTO ingest.lift_tuckets_import_by_insert_into_select
+SELECT * FROM ingest.lift_tuckets_import_by_studio_web;
+```
+
+#### 方式三：从Volume文件查询数据并导入
+
+##### 使用场景
+
+云器 Lakehouse 支持通过 `INSERT INTO` 与 `SELECT FROM VOLUME` 结合使用，直接从外部文件（如云存储中的 CSV 或 Parquet 文件）导入数据。
+
+注：在 ZettaPark 上传数据文件的案例中，已将 CSV、JSON 格式的数据文件上传至云器 Lakehouse 的数据湖对象 ingest_demo 中。
+
+##### 实现步骤
+
+导航到 开发 -> 任务，单击 “+” 新建一个 SQL 任务。
+
+```SQL
+DROP TABLE IF EXISTS ingest.lift_tuckets_import_by_insert_into_select_from_volume;
+CREATE TABLE IF NOT EXISTS ingest.lift_tuckets_import_by_insert_into_select_from_volume(
+  `txid` string,
+  `rfid` string,
+  `resort` string,
+  `purchase_time` timestamp_ltz,
+  `expiration_time` date,
+  `days` int,
+  `name` string,
+  `address_street` string,
+  `address_city` string,
+  `address_state` string,
+  `address_postalcode` string,
+  `phone` string,
+  `email` string,
+  `emergency_contact_name` string,
+  `emergency_contact_phone` string);
+
+
+--使用SELECT文件的结果导入数据
+--查看上传至Volume的数据文件
+SHOW VOLUME  DIRECTORY ingest.ingest_demo;
+
+--使用CSV格式数据文件导入
+INSERT INTO ingest.lift_tuckets_import_by_insert_into_select_from_volume 
+select * from volume ingest_demo(
+  `txid` string,
+  `rfid` string,
+  `resort` string,
+  `purchase_time` timestamp_ltz,
+  `expiration_time` date,
+  `days` int,
+  `name` string,
+  `address_street` string,
+  `address_city` string,
+  `address_state` string,
+  `address_postalcode` string,
+  `phone` string,
+  `email` string,
+  `emergency_contact_name` string,
+  `emergency_contact_phone` string
+) using csv
+ options(
+    'header'='true',
+    'sep'=',',
+    'compression' = 'gzip'
+ ) files('gz/lift_tickets_data.csv.gz');
+ 
+--使用JSON格式数据文件导入
+INSERT INTO ingest.lift_tuckets_import_by_insert_into_select_from_volume  
+select * from volume ingest_demo(
+        `txid` string,
+        `rfid` string,
+        `resort` string,
+        `purchase_time` timestamp_ltz,
+        `expiration_time` date,
+        `days` int,
+        `name` string,
+        `address_street` string,
+        `address_city` string,
+        `address_state` string,
+        `address_postalcode` string,
+        `phone` string,
+        `email` string,
+        `emergency_contact_name` string,
+        `emergency_contact_phone` string
+        ) using json
+options(
+'compression' = 'gzip'
+) files('gz/lift_tickets_data.json.gz');
+```
+
+除 CSV、JSON 格式外，云器 Lakehouse 还支持通过 SELECT FROM VOLUME 方式查询 Parquet、ORC、BSON 等开放格式的数据并导入。

+# 将数据导入云器 Lakehouse 的完整指南
+
+## 数据入湖：通过 ZettaPark PUT 文件实现数据入湖
+
+#### 概述
+
+通过云器 Lakehouse 提供的 ZettaPark Python 库，以 Python 编程的方式将在测试数据生成步骤中生成的数据上传到云器 Lakehouse 管理的数据湖中，实现数据入湖。
+
+数据湖操作需要新建一个数据湖连接和 Volume，然后就可以将数据 PUT 到数据湖中。
+
+#### 使用场景
+
+适合熟悉 Python 编程的用户，可以借助 Python 强大的编程能力和灵活性，通过 Python 和 DataFrame 进行数据清洗、转换等数据工程与数据准备工作，特别是与 AI 分析紧密相关的数据工作。
+
+#### 实现步骤
+
+你也可以[直接下载文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/put_data_to_datalake_by_Zettapark.ipynb)到本地。
+
+##### **将本地文件通过 Zettapark PUT 到云器 Lakehouse 管理的数据湖（Volume）**
+
+```Python
+# !pip install clickzetta_zettapark_python  -i https://pypi.tuna.tsinghua.edu.cn/simple
+```
+
+```Python
+from clickzetta.zettapark.session import Session
+import json,requests
+import os
+from datetime import datetime
+```
+
+##### **创建到云器 Lakehouse 的会话**
+
+```Python
+# 从配置文件中读取参数
+with open('config/config-ingest.json', 'r') as config_file:
+    config = json.load(config_file)
+
+print("正在连接到云器Lakehouse.....\n")
+
+# 创建会话
+session = Session.builder.configs(config).create()
+
+print("连接成功！...\n")
+```
+
+正在连接到云器 Lakehouse...
+
+连接成功！
+
+##### **将文件 PUT 到云器 Lakehouse 数据湖 Volume**
+
+请将 `data/` 改为在“测试数据生成”步骤中生成的数据存放目录。
+
+```Python
+for filename in os.listdir("data/"):
+        if filename.endswith(".gz"):
+            file_path = os.path.join("data/", filename)
+            session.file.put(file_path,"volume://ingest_demo/gz/")
+        if filename.endswith(".csv"):
+            file_path = os.path.join("data/", filename)
+            session.file.put(file_path,"volume://ingest_demo/csv/")
+        if filename.endswith(".json"):
+            file_path = os.path.join("data/", filename)
+            session.file.put(file_path,"volume://ingest_demo/json/")
+```
+
+```Python
+# 或者上传目录下所有的文件# session.file.put("../data/","volume://ingest_demo/gz/")
+```
+
+##### **再次同步数据湖 Volume 的目录到 Lakehouse**
+
+```Python
+session.sql(alter_datalake_sql).show()
+```
+
+\---------------------
+
+|result\_message |
+
+\---------------------
+
+| OPERATION SUCCEEDED |
+
+\---------------------
+
+##### **再次查看云器 Lakehouse 数据湖 Volume 上的文件**
+
+```Python
+results = session.sql("select * from directory(volume ingest_demo)").show()
+```
+
+\----------------------------------------------------------------------------------------------------------------------------
+
+|relative\_path |url |size |last\_modified\_time |
+

+
+\----------------------------------------------------------------------------------------------------------------------------
+
+##### **测试将数据湖上文件再拉回到本地**
+
+```Python
+session.file.get("volume://ingest_demo/gz/lift_tickets_data.json.gz","tmp/gz/")
+```
+
+\[GetResult(file='tmp/gz/lift\_tickets\_data.json.gz', size=11146044, status='DOWNLOADED', message='')]
+
+##### 校验数据湖文件的行数
+
+数据校验：检查文件行数。查询结果为 100000，与原文件行数一致。简单从行数判断，数据入湖正确。
+
+```Python
+datalake_data_verify_sql = """
+select count() from volume ingest_demo (txid string) using csv
+ options(
+    'header'='true',
+    'sep'=',',
+    'compression' = 'gzip'
+ ) files('gz/lift_tickets_data.csv.gz')
+ limit 10
+"""
+```
+
+```Python
+session.sql(datalake_data_verify_sql).show()
+```
+
+\-------------
+
+|`count`() |
+
+\-------------
+
+|100000 |
+
+\-------------
+
+##### 查询数据湖文件里的数据
+
+```Python

+# 将数据导入云器Lakehouse的完整指南
+
+## 数据入仓：通过Zettapark以SAVE\_AS\_TABLE方式加载数据
+
+#### 概述
+
+#### 使用场景
+
+SAVE\_AS\_TABLE方式会自动建表，从而简化了通过Zettapark以SQL INSERT方式加载数据需要手工建表的过程，同时SAVE\_AS\_TABLE会自动优化INSERT INTO，每次不是插入一条记录而是多条。
+
+#### 实现步骤
+
+在电脑上打开VS Code，创建一个名为 [py\_zettapark\_save\_as\_table.py ](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/py_zettapark_save_as_table.py)的文件，并将以下代码复制到py\_zettapark\_save\_as\_table.py文件中。
+
+```Python
+import json
+import gzip
+from clickzetta.zettapark.session import Session
+from datetime import datetime
+
+# 从配置文件中读取参数
+with open('config-ingest.json', 'r') as config_file:
+    config = json.load(config_file)
+
+print("正在连接到云器Lakehouse.....\n")
+
+# 创建会话
+session = Session.builder.configs(config).create()
+
+print("连接成功！...\n")
+
+target_table_name = "lift_tuckets_import_by_py_save_as_table"
+
+def save_as_table_to_clickzetta(session, schema, data):
+    print('Saving data to Clickzetta Lakehouse')
+
+    # Convert data to dataframe
+    df = session.create_dataframe(data, schema=schema)
+    
+    # Save dataframe as table
+    df.write.save_as_table(target_table_name, mode="overwrite", table_type="transient")
+    print(f"Data saved to table {target_table_name}")
+
+if __name__ == "__main__":
+    schema = None
+    data = []

+# 将数据导入云器Lakehouse的完整指南
+
+## 数据入仓：通过Zettapark以SQL INSERT方式加载数据
+
+#### 概述
+
+云器Lakehouse提供了和PySpark兼容的[Zettapark](ZettaparkQuickStart.md)，在流行的IDE（比如VS Code）里通过Python和SQL编程的方式，将数据加载到云器Lakehouse的表里。
+
+#### 使用场景
+
+这种方式可以方便地运行 SQL 并上传文件，加载数据的一种方法是对每条记录执行 SQL INSERT 语句，适合在 Python 编程环境里上传少量数据。虽然这是一种方便的数据插入方式，但是对大批量数据的加载效率不高，因为云器Lakehouse并不是一个传统的数据库，而是针对写入大批量数据进行了更多优化。
+
+#### 实现步骤
+
+在电脑上打开VS Code，创建一个名为 [py\_zettapark\_sql\_insert.py ](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/py_zettapark_sql_insert.py)的文件，并将以下代码复制到py\_zettapark\_sql\_insert.py文件中。

+
+> 本教程借助 Lakehouse Tutorial 智能助手，提供了在线教程指南以及脚本导入功能。您可以在登录 Lakehouse Web 控制台后，通过 Lakehouse Tutorial 的“Lakehouse教程”入口进入教程，并根据在线指南引导完成教程。
+> ![](.topwrite/assets/image_1736854951691.png)
+
+### 导入脚本
+
+打开控制台 Tutorial 页面中的“Lakehouse教程”，选择“通过横向弹性扩容支持多并发查询”课程。根据页面提示导入本次课程需要的脚本文件。
+
+在“开发”模块查看“Tutorial_Working_With_Concurrency_Scaling”目录。
+
+![](.topwrite/assets/image_1725287877169.png =436)
+
+### 入门知识
+
+虚拟计算集群（Virtual Cluster，简称 VC 或集群）是云器 Lakehouse 提供数据处理和分析的计算资源对象。虚拟计算集群提供在 Lakehouse 中执行 SQL 作业所需的 CPU、内存、本地临时存储（SSD 介质）等资源。集群具备快速创建/销毁、扩容/缩容、暂停/恢复等特点，按照资源规格大小以及使用时长进行收费，暂停或删除后不产生费用。虚拟计算集群针对 ETL 和分析场景，提供通用型和分析型两种集群类型，以满足不同负载的隔离和优化需求。
+
+![](.topwrite/assets/image_1714992266569.png =700)
+
+### 教程步骤
+
+1.  **环境准备**：创建测试使用的计算集群。
+2.  **发起查询**：使用 Studio Web 环境创建 Python 任务对 Lakehouse 使用不同并发度进行连续查询，观察 Python 任务的执行日志结果，了解集群在不同并发请求下的快速扩缩容能力。
+3.  **清理环境**：删除测试使用的计算集群。
+
+通过以上步骤，您将能够了解如何配置和使用虚拟集群的弹性并发功能，并了解其性能表现。
+
+## 准备工作
+
+首先，通过 SQL 命令来创建分析型计算集群，并开启和设置弹性并发功能。
+
+本教程通过在“开发”模块运行 [Tutorial_Working_With_Concurrency_Scaling->Step01.Preparation] SQL 脚本任务来创建集群，并设置弹性扩容策略。
+![](.topwrite/assets/image_1725288058473.png)
+
+## 使用Python程序发起并发查询
+
+在“开发”模块打开 [Tutorial_Working_With_Concurrency_Scaling->Step02.Run_Concurrent_Queries] Python 并发任务模板，您需要修改 connect 连接配置参数，才能连接 Lakehouse 并执行查询。
+
+![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tu_concurrent_connection.png?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=1880895431\&Signature=B2eODbnltYz%2FzjifxINWWzcf%2Bzw%3D)
+
+修改连接信息后，请点击任务运行，并查看任务执行日志。
+
+![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tu_concurrent_report.png?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=1880982939\&Signature=%2B1YAL8o1IDjFdlaIpBgxB0Sa%2B90%3D)
+通过观察打印的性能报告，可以发现 Reporting_VC 集群随着客户端并发请求的梯度增加，通过动态增加副本（Replica）数量，实现了毫秒级延迟的横向扩容。在动态扩容的同时，仍能保持对持续并发请求的查询服务等级协议（SLA）。
+
+在执行任务的同时，您也可以通过集群监控页面查看集群的并发请求以及弹性扩容情况。

+# 数据源管理
+
+## 简介
+
+本文档旨在指导用户如何配置和管理数据源，以便在 Lakehouse 产品中实现高效的数据同步任务。通过本文档，您将了解如何添加不同类型的数据源，并通过 SSH Tunnel 连接 VPC 内的数据源。
+
+## 操作步骤
+
+1. **登录与访问数据源管理页面**
+
+   首先，登录Lakehouse产品控制台。在控制台首页，选择“管理”模块，点击进入“数据源”页面。您将看到一个数据源列表，显示了当前已配置的所有数据源。

+3. **填写数据源定义并进行连通性测试**
+
+   根据您选择的数据源类型，填写相应的连接信息。例如，对于 MySQL 数据源，您需要提供数据库地址、端口、用户名、密码等信息。填写完毕后，点击“测试连接”按钮，以确保所填写的信息正确无误。
+
+   ![](.topwrite/assets/image_1728993014881.png =640)
+
+## 通过SSH Tunnel连接VPC内数据源
+
+### 前置条件
+
+1. **VPC内数据源访问限制**
+
+   确保您的 VPC 内数据源（如阿里云 RDS for MySQL 数据库）仅提供内网访问。这意味着数据源不对外公开，从而提高了数据安全性。
+
+2. **SSH Tunnel服务器准备**
+
+   准备一台位于 VPC 内的 ECS 服务器，该服务器应具备公网访问能力，并支持 SSH 登录。此外，确保数据同步服务可以通过公网访问到这台 ECS 服务器。
+
+3. **VPC内网络访问配置**
+
+   确保 VPC 内的 ECS 服务器可以通过内网 IP 或域名访问 VPC 内的数据源。这将便于在建立 SSH Tunnel 时，数据同步服务能够顺利连接到数据源。
+
+### 配置数据源连接参数
+
+在新建数据源页面中，启用“通过 SSH Tunnel 连接”选项。根据页面提示，填写以下信息：
+
+* **SSH Tunnel服务器公网地址**：输入 VPC 内 ECS 服务器的公网 IP 地址或域名。
+* **SSH端口**：输入 ECS 服务器上 SSH 服务的端口号（默认为 22）。
+* **SSH用户名**：输入用于SSH登录的用户名。
+* **SSH密码**：输入对应的SSH登录密码。
+
+![](.topwrite/assets/image_1690124173674.png =640)
+
+完成以上配置后，点击“测试连接”按钮。如果连接成功，您将看到一个绿色的勾号提示。这意味着数据同步服务在任务启动时，可以通过 SSH Tunnel 与 VPC 内的数据源建立网络连接。
+
+## 使用示例
+
+### 示例1：连接阿里云RDS for MySQL数据库
+
+1. 在数据源类型选择页面，选择“MySQL”作为数据源类型。
+2. 在数据源定义页面，填写以下信息：
+   * 主机名/地址：填写阿里云 RDS for MySQL 的内网 IP 地址。

+## 前提条件
+
+在开始使用客户端之前，请确保满足以下条件：
+
+1. 您的设备已安装 Java 8 或更高版本。
+2. 您已在 Clickzetta 官网注册账户，并创建了 Lakehouse 服务实例。
+3. 您已创建用于连接访问的工作空间。
+4. 使用客户端的用户身份已被添加至工作空间，并被授权访问。
+
+## 安装客户端
+
+Clickzetta Lakehouse 的命令行客户端基于开源 SQL Line 项目进行二次开发。请按照以下步骤安装并配置客户端：
+
+1. 从公网下载或通过Clickzetta工作人员获取客户端安装包[sqlline\_cz.tar.gz](https://autolake-dev-beijing.oss-cn-beijing.aliyuncs.com/clickzetta-tool/release/sqlline_cz.tar.gz)。
+2. 解压安装包文件，您将获得客户端工具的可执行文件和配置文件。
+
+```
+% tar -zxvf sqlline_cz.tar.gz
+x sqlline_cz/
+x sqlline_cz/example.properties
+x sqlline_cz/log4j.properties
+x sqlline_cz/setup.sh
+x sqlline_cz/sqlline
+x sqlline_cz/sqlline-2.13.0-SNAPSHOT-jar-with-dependencies.jar
+```
+
+## 初始化连接环境
+
+1. 进入工作目录：
+
+```
+cd sqlline_cz
+```
+
+2. 初始化连接环境：
+   主要作用是下载最新的 JDBC 驱动包并放到 `sqlline_cz` 目录下。您也可以通过下方链接下载最新的 JDBC 驱动包，并放到 `sqlline_cz` 目录下。
+
+* [下载地址一](https://mvnrepository.com/artifact/com.clickzetta/clickzetta-java)
+* [下载地址二](https://central.sonatype.com/artifact/com.clickzetta/clickzetta-java/versions)
+
+```
+sh setup.sh
+```
+
+## 配置客户端连接
+
+### 方式1：命令行指定连接参数
+
+通过命令行指定连接参数的方式如下：
+
+```
+sh sqlline -d com.clickzetta.client.jdbc.ClickZettaDriver -u "<JDBC URL>" -n <user_name> -p <password>
+```
+
+JDBC URL 格式：
+
+```
+jdbc:clickzetta://<instance_name>.<region_id>.api.clickzetta.com/<workspace_name>?schema=<默认schema名称>&virtualCluster=<计算集群名称>
+```
+
+参数说明：
+
+* `<JDBC URL>`：当前服务实例的 JDBC 连接串，详细格式详见 [JDBC驱动](JDBC-Driver.md)。
+* `<user_name>`：目标工作空间中的空间成员的用户名。
+* `<password>`：目标工作空间中的空间成员的密码。
+* `schema`：指定要连接的 schema，必须填写。
+* `virtualCluster`：使用的计算资源，必须填写。
+
+示例：
+
+```
+sh sqlline -d com.clickzetta.client.jdbc.ClickZettaDriver -u "jdbc:clickzetta://<lakehouse_instance_name>.cn-shanghai-alicloud.api.clickzetta.com/<workspace_name>?schema=<target_schema_name>&vcluster=<your_virtualcluster_name>" -n <user_name> -p <your_password>
+```
+
+### 方式2：命令行指定配置文件
+
+命令行工具提供了配置文件模板。您可以修改该配置文件，然后在命令行中指定该文件以实现服务连接。样例配置文件格式如下：
+
+```
+url=jdbc:clickzetta://<Lakehouse_instance_name>.<region_id>.api.clickzetta.com/<workspace_name>?schema=<schma_name>&virtualCluster=<vcluster_name>
+driver=com.clickzetta.client.jdbc.ClickZettaDriver
+user=<your_user_name>
+password=<your_password>
+```
+
+根据您的服务信息修改模板配置文件并保存后，通过命令参数指定配置文件的方式进行服务连接。
+
+```
+$ sh sqlline properties <配置文件名>
+```
+
+示例：
+
+```
+$ sh sqlline properties test.properties
+sqlline version 1.13.0-SNAPSHOT
+0: jdbc:clickzetta://xxxx.region_id.api.clickzetta.com>show tables;
+```
+
+Clickzetta Lakehouse 命令行工具可一次创建多个不同的服务连接配置文件。在使用过程中，可借助 `!properties` 命令快速切换不同配置文件对应的服务连接。以下以将配置文件从 test.properties 切换为 test.properties.1 为例：
+
+```
+sqlline> !properties test.properties
+Transaction isolation level TRANSACTION_REPEATABLE_READ is not supported. Default (TRANSACTION_READ_COMMITTED) will be used instead.
+0: jdbc:clickzetta://xxxx.region_id.api.clickzetta.com> !properties test.properties.1
+Transaction isolation level TRANSACTION_REPEATABLE_READ is not supported. Default (TRANSACTION_READ_COMMITTED) will be used instead.
+1: jdbc:clickzetta://yyyyy.region_id.api.clickzetta.com> !go 0
+0: jdbc:clickzetta://xxxx.region_id.api.clickzetta.com>
+```
+
+## 运行SQL命令
+
+连接成功后，您可以在命令行客户端执行 Lakehouse SQL 命令。以下是一些SQL命令示例：
+
+切换要使用的 vcluster 和 schema
+
+```
+use vcluster default;
+use schema nyc_taxi_data;
+```
+
+查看当前 schema 中有哪些表
+
+```
+show tables;
+```
+
+![](.topwrite/assets/image_1699879449976.png)
+查询数据
+
+```
+select  * from fhv_trips_staging limit 10;
+```
+
+![](.topwrite/assets/image_1699879794959.png)
+
+## 退出客户端
+
+```
+!quit
+```
+
+## 备注
+
+通过在当前环境中设置以下环境变量，可以打开 debug 模式并输出日志文件，方便问题排查。
+
+```
+export SQLLINE_DEBUG_ENABLE=TRUE
+```

+# CONNECTION
+
+在Lakehouse中，CONNECTION对象扮演着至关重要的角色。它负责存储第三方服务的身份认证信息和访问管理凭据，从而实现在数据处理过程中保护敏感信息的目的。通过使用CONNECTION，用户无需将身份认证信息以明文形式暴露，从而确保数据的安全性。此外，CONNECTION还支持STS（Security Token Service）认证方式，允许跨账号授权访问Lakehouse以外的服务，进一步提高了数据访问的灵活性和安全性。
+
+## CONNECTION的类型
+
+根据其用途和连接的外部服务类型，CONNECTION对象主要分为以下三种类型：
+
+1. **API Connection**：这种类型的CONNECTION主要用于存储和保护第三方应用服务的身份认证信息。通过API Connection，Lakehouse可以安全地通过API调用来与这些服务进行交互。目前，API Connection支持的外部服务包括阿里云的函数计算FC和腾讯云的云函数服务。API Connection通常与External Function结合使用，以便在Lakehouse中远程调用这些服务。
+2. **Storage Connection**：Storage Connection主要用于存储第三方存储服务的身份认证信息，使得Lakehouse能够安全地访问和管理这些存储服务中的数据。目前支持的外部存储服务包括阿里云的对象存储OSS、腾讯云COS和AWS S3。
+3. **Catalog Connection**：在数据湖架构中，Catalog Connection 是一种关键组件，用于将数据湖与外部的元数据存储（例如 Hive Metastore）关联起来。通过创建 Catalog Connection，用户可以实现元数据的统一管理和访问，从而直接读取存储在外部系统中的数据。Lakehouse目前只支持连接Hive。
+
+## 创建和管理CONNECTION
+
+为了使用CONNECTION，用户需要了解如何创建、列出、查看详情以及删除CONNECTION。以下是这些操作的基本语法和使用示例：
+
+* **创建CONNECTION**：用户可以通过特定的创建语法来定义一个新的CONNECTION对象，其中需要指定CONNECTION的类型、名称以及相关的认证信息和参数。
+  例如，创建一个API Connection的语法如下：
+
+  ```sql
+  CREATE API CONNECTION conn_aliyun_java 
+    type cloud_function
+    provider = 'xxx'
+    region = 'xxx'
+    role_arn = 'acs:ram::13843xxxxxxxxxxxxx:role/czudfrole'
+    namespace = 'xxx'
+    code_bucket = 'xxx';
+  ```
+
+  创建一个Storage Connection的语法如下：
+
+  ```SQL
+  CREATE STORAGE CONNECTION [IF NOT EXISTS] connection_name 
+    TYPE COS
+    REGION = 'xxx'
+    APP_ID = 'xxx'
+    ACCESS_KEY='******'
+    SECRET_KEY='******';
+  ```
+
+  具体的语法和步骤可以参考[创建CONNECTION](CREATECONNECTION.md)文档。
+
+* **列出所有的CONNECTION**：用户可以使用列出语法来查看当前Lakehouse工作空间中所有的CONNECTION对象。例如，查看当前CONNECTION的命令如下：
+  ```sql
+  SHOW CONNECTIONS;
+  ```
+  这有助于用户管理和选择已有的CONNECTION进行操作。相关的命令和选项可以在[列出所有的CONNECTION](SHOWCONNECTIONS.md)文档中找到。
+
+* **查看CONNECTION详情**：为了更好地理解和管理CONNECTION，用户可能需要查看特定CONNECTION的详细信息。这包括认证信息、配置参数等。例如，查看一个API Connection详情的语法如下：
+  ```sql
+  DESCRIBE CONNECTION my_api_conn;
+  ```
+  查看详情的语法和方法在[查看CONNECTION详情](DESCCONNECTION.md)文档中有详细说明。
+
+* **删除CONNECTION**：当某个CONNECTION不再需要时，用户可以通过删除语法来移除它。例如，删除一个CONNECTION的命令如下：
+  ```sql
+  DROP CONNECTION my_api_conn;
+  ```
+  这有助于保持工作空间的整洁，并防止不必要的安全风险。具体的删除步骤和注意事项在[删除CONNECTION](DROPCONNECTION.md)文档中有所描述。

+# 流式SQL
+
+>【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请联系我们的技术支持同学协助处理。
+
+
+
+流式SQL是Lakehouse平台推出的一种新型SQL调度模式，它采用微批处理运行机制，支持设置秒级的数据刷新间隔，类似于Spark Streaming的微批执行方式。与传统的定时调度相比，流式SQL能够显著减少提交和编译SQL的开销，因为它将提交的SQL转化为一个常驻进程，一旦达到设定的时间间隔，就会自动触发数据的运行和处理。流式SQL目前是面向需要数据新鲜度更高的场景，目前支持dt刷新和加工数据过程中含有table stream。
+
+为了更清晰地理解流式SQL的优势，我们可以将其与普通SQL的执行过程进行对比：
+
+**普通SQL执行过程**
+
+![](.topwrite/assets/image_1727083232762.png)
+
+* 语法解析器（Parser），词法分析，语法分析将SQL文本解析成抽象语法树（AST），语义分析，类型推导和检查。生产Logical Plan
+
+* 查询优化器（Optimizer）：通过Rule对Plan进行变换，根据cost model找出best plan
+
+  * RBO：基于规则的优化器，通过用户下发的SQL语句进行的优化，主要通过改下SQL，比如SQL子句的前后执行顺序等。比较常见的优化包括谓语下推、字段过滤下推、常量折叠、索引选择、Join优化等等
+  * CBO：基于代价的优化器，根据收集的统 计信息来计算每种执行方式的代价，进而选择最优的执行方式
+  * HBO：History-Based Optimizer，基于历史的优化器
+
+* 生成DAG图：DAG描述了执行计划映射到物理分布式集群的具体描述，根据执行计划，分布式执行，体现的是执行计划被物化到分布式系统上，具备的一些特性：比如并发度，数据传输方式等等，保证有序性和可靠性
+
+* Executor读取数据进行运算
+
+**流式SQL执行过程**
+
+1. **首次提交与物理执行计划生成**：
+
+   1. 在流式SQL首次提交时，系统会进行完整的编译过程，包括语法解析、查询优化和物理执行计划的生成。
+   2. 这一阶段生成的物理执行计划（DAG图）将被固化，用于后续的执行周期。
+
+2. **后续执行的优化**：
+
+   1. 物理执行计划生成并固化，后续的执行周期在大部分情况下将直接使用这一计划，无需再次进行编译。
+   2. 这意味着每次数据到达时，流式SQL可以跳过耗时的解析和优化步骤，直接进入执行阶段。
+   3. 在执行过程中，优化器也会监测每次要处理的数据量，如果数据量变化非常大使得执行计划不是最优时，优化器会重新生成物理执行计划并固化。
+
+#### 定时调度与流式SQL的对比
+
+* **普通定时调度**：
+
+  * 每次执行前都需要重新解析和优化SQL，这增加了额外的开销。
+  * 时间间隔通常需要设置得相对较大，以减少调度的频率和资源消耗。
+
+* **流式SQL**：
+
+  * 由于省去了重复的编译过程，流式SQL可以支持更小的时间间隔，实现更高频的数据更新和处理。
+  * 这种模式特别适合需要实时或近实时数据处理的应用场景
+
+# 流式SQL适用场景
+
+流式SQL的引入，为数据处理带来了更高的灵活性和实时性。在动态表（dynamic table）的DDL（Data Definition Language）定义中，调度的时间间隔通常有一个最小值，例如一分钟。这意味着数据的更新和处理至少会有一个一分钟的延迟。然而，流式SQL通过微批处理机制，允许将这个时间间隔缩短到秒级，从而实现更快速的数据反应和处理。
+
+* **实时数据处理**：流式SQL能够快速响应数据变化，适合需要实时数据处理和分析的应用。
+* **高频数据更新**：对于需要频繁更新数据的系统，流式SQL可以减少每次更新的延迟，提高数据处理的实时性。
+
+# 流式SQL使用限制
+
+* 要求流式是动态表或者SQL加工中含有table stream。普通SQL暂时不支持
+* 作业必须运行在分析型（ap）集群
+* 目前只支持在Lakehouse 界面开发流式SQL。一个SQL文件中只能处理一个DML SQL任务
+
+# 流式SQL如何使用
+
+## 开发流式SQL任务
+
+1. 数据开发中新建流式SQL节点
+   ![](.topwrite/assets/image_1727083278915.png)
+
+2. 编写SQL任务
+
+提交的SQL任务中只能有一条DML SQL语句。在开发阶段可以编写任何SQL，目前是没有限制。但是在启动阶段会校验SQL是不是符合流式SQL。
+
+流式SQL要求
+
+* 要求流式是动态表或者SQL加工中含有table stream
+* 作业必须运行在分析型（ap）集群
+* 一个SQL文件中只能处理一个SQL任务
+
+**配置处理间隔**
+
+点击配置按钮，刷新间隔用来配置多长时间处理一次，目前最短时间是1s
+![](.topwrite/assets/image_1727083303138.png)
+
+## 运行流式SQL任务

+
+监控告警中支持监控流式SQL任务执行失败告警
+
+![](.topwrite/assets/image_1727083445006.png)
+
+# 流式SQL使用具体案例
+
+## TABLE STREAM使用流式SQL
+
+本次案例使用TABLE STREAM实现缓慢变化维第一种覆盖更新。并使用流失SQL的微批处理保证数据的新鲜度。
+
+[缓慢变化维度](https://developer.baidu.com/article/detail.html?id=371363)（Slowly Changing Dimension，SCD）是数据仓库中处理数据变更的一种方法。在数据仓库中，数据通常是从多个数据源整合而来的。随着时间的推移，这些数据源中的数据可能会发生变化，例如更新、添加或删除。缓慢变化维度是一种用于处理和更新这些数据变化的技术。SCD有多种类型，SCD1：覆盖更新，SCD2：历史记录等
+
+我们模拟当原表数据发生变化时，通过流失SQL加工，缓慢变化维表也会变化。
+
+1. 新建一个普通SQL节点。执行一下SQL。用于创建原表并插入一些测试数据，和开启table stream捕获原表的变化
+
+```SQL
+create schema continuous_job;
+drop table if exists continuous_job.test_table_offset;
+drop table stream  if exists continuous_job.test_table_offset_stream;
+-- 创建原表
+CREATE TABLE continuous_job.test_table_offset (id INT, name VARCHAR, age INT);
+--创建table stream时必须开启
+ALTER TABLE continuous_job.test_table_offset set PROPERTIES ('change_tracking' = 'true');
+CREATE table stream continuous_job.test_table_offset_stream ON TABLE continuous_job.test_table_offset
+WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
+-- 插入一些数据到测试表
+INSERT INTO continuous_job.test_table_offset VALUES
+  (1, 'Alice', 20),
+  (2, 'Bob', 25),
+  (3, 'Charlie', 30),
+  (4, 'David', 35),
+  (5, 'Eve', 40);
+```
+
+2. 创建一张缓慢变化维表，用于保持和原表一致
+
+```SQL
+drop table  if exists test_table_offset_consume;
+-- 创建目标表
+CREATE TABLE continuous_job.test_table_offset_consume (id INT, name VARCHAR, age INT);
+```
+
+3. 新建一个流式SQL节点，将下面SQL复制到流式SQL节点中。我们设置20秒间隔处理一次数据
+
+```SQL
+MERGE INTO continuous_job.test_table_offset_consume target USING continuous_job.test_table_offset_stream source_stream ON target.id = source_stream.id WHEN MATCHED
+AND source_stream.__change_type = 'UPDATE_AFTER' THEN update set target.age = source_stream.age WHEN MATCHED
+AND source_stream.__change_type = 'DELETE' THEN DELETE WHEN NOT MATCHED
+AND source_stream.__change_type = 'INSERT' THEN
+INSERT VALUES (target.id, target.name, target.age);
+```
+
+![](.topwrite/assets/image_1727083470402.png)
+
+4. 提交流式SQL，并且在运维中心点击启动
+
+![](.topwrite/assets/image_1727083486439.png)
+
+5. 通过更新原表数据，流式SQL运行成功之后。SCD表也会和流式SQL保持一致
+
+* 普通节点执行SQL
+
+```SQL
+-- 更新一些原表数据
+update continuous_job.test_table_offset set age = age + 5 WHERE id = 1 OR id = 3;
+--等待20s，continues job执行成功。校验scd表和原表数据是否一致
+select "test_table_offset", * from continuous_job.test_table_offset
+union all
+SELECT "test_table_offset_consume",* FROM continuous_job.test_table_offset_consume;
+
+-- 删除一些数据到测试表
+DELETE FROM continuous_job.test_table_offset WHERE id = 2 OR id = 4;
+--等待20s,continues job执行成功。校验scd表和原表数据是否一致
+select "test_table_offset", * from continuous_job.test_table_offset
+union all
+SELECT "test_table_offset_consume",* FROM continuous_job.test_table_offset_consume;
+```
+
+6. 清理环境
+
+* 运维中心中停止流式SQL
+  ![](.topwrite/assets/image_1727083510506.png)
+
+* 删schema
+
+```SQL
+drop schema continuous_job;
+```
+
+## Dynamic Table使用流式SQL
+
+本次案例使用dynamic table对数据按时间进行聚合。利用流式SQL微批调度提高数据新鲜度
+
+* 创建一ods表
+
+```SQL
+CREATE TABLE event_tb (
+    event STRING,
+    process DOUBLE,
+    event_time TIMESTAMP
+  );
+INSERT INTO event_tb VALUES
+  ('event-0', 20.0, TIMESTAMP '2023-09-20 14:43:13'),
+  ('event-0', 20.0, TIMESTAMP '2023-09-19 11:40:13'),
+  ('event-1', 21.0, TIMESTAMP '2023-09-19 14:30:14'),
+  ('event-1', 22.0, TIMESTAMP '2023-09-20 14:20:15');
+```
+
+* 使用动态表进行聚合。在普通SQL节点中创建动态表，注意不要在ddl中设置调度周期
+
+```SQL
+CREATE dynamic table IF NOT EXISTS event_group_minute AS
+SELECT
+  event,
+  hour(event_time) hour,
+  year(event_time) year,
+  SUM(process) process_sum
+FROM
+  event_tb
+GROUP BY
+  event,
+  year(event_time),
+  hour(event_time);
+```
+
+* 新建流式SQL节点，将下面SQL复制到节点内容中，并配置10s运行一次
+
+```SQL
+refresh dynamic table event_group_minute;
+```
+
+![](.topwrite/assets/image_1727083531426.png)
+
+* 启动流式SQL刷新动态表
+
+![](.topwrite/assets/image_1727083554105.png)
+
+* 新建普通SQL节点，向表原表中插入一些数据，查询动态表是否刷新成功
+
+```SQL
+
+  INSERT INTO event_tb VALUES
+  ('event-0', 20.0, TIMESTAMP '2024-09-20 14:43:13'),
+  ('event-0', 20.0, TIMESTAMP '2024-09-19 11:40:13'),
+  ('event-1', 21.0, TIMESTAMP '2024-09-19 14:30:14'),
+  ('event-1', 22.0, TIMESTAMP '2024-09-20 14:20:15');
+  
+  --等待10s观察动态表变化
+  select * from event_group_minute;  
+```

+
+# 语法
+
+```SQL
+--直接从VOLUME中导入数据
+COPY INTO|OVERWRITE table_name
+ [PARTITION (partition_column_name = partition_column_val)]
+FROM VOLUME volume_name
+[( <column_name> <column_type>,...) ]
+USING CSV | PARQUET | ORC | BSON
+OPTIONS(
+  FileFormatParams
+) 
+FILES('filename1','fiename2'...)|SUBDIRECTORY 'path'|REGEXP <pattern>
+PURGE=TRUE
+ON_ERROR=TRUE|ABORT;
+
+--导入过程中进行转化
+COPY INTO table_name FROM (
+SELECT  <column_name>,... 
+FROM VOLUME <volume_name>
+[(<column_name> <column_type>,...) ]
+USING CSV|PARQUET|ORC 
+OPTIONS(
+  FileFormatParams
+) 
+FILES|SUBDIRECTORY|REGEXP <pattern>
+)
+PURGE=TRUE
+ON_ERROR=CONTINUE|ABORT;
+```
+
+### 使用说明
+
+COPY INTO 语句后面可以直接使用 VOLUME 查询语法，可以在导入过程中直接转换数据，VOLUME 查询[参考结构化、半结构化数据分析](structure_data_analysis.md)
+
+### **参数说明**：
+
+* **OVERWRITE**\|**INTO**:
+  * **INTO**：追加模式。使用 `INTO` 子句进行数据导入时，新数据将被追加到目标表，这种模式不会删除或修改表中的现有数据。
+  * **OVERWRITE**：覆盖模式。使用 `OVERWRITE` 子句进行数据导入时，目标表中的现有数据将被清空，然后导入新数据。这种模式适用于需要用新数据完全替换旧数据的场景。
+
+```
+--向表中追加数据
+CREATE TABLE birds (
+    id INT,
+    name VARCHAR(50),
+    wingspan_cm FLOAT,
+    colors STRING
+);
+COPY INTO birds FROM 
+VOLUME  my_volume
+USING csv
+SUBDIRECTORY 'dau_unload/read/';
+--覆盖表中的的数据
+COPY OVERWRITE birds FROM 
+VOLUME  my_volume
+USING csv
+SUBDIRECTORY 'dau_unload/read/';
+```
+-  [PARTITION (partition_column_name = partition_column_val)],直接指定分区列的值，例如 `PARTITION (dt='shanghai')`。
+* **column\_name**和**column\_type**：可选，lakehouse支持自动识别文件schema。推荐不填写。当指定文件中包含的列名和类型时，需与文件中预定义的列类型相匹配，
+  * 自动识别文件 schema 对于 CSV 文件则会自动生成字段，字段编号以 f0 开始。目前自动识别的类型为 int、double、string、bool。
+  * 对于parquet、orc格式将会根据文件中存储的字段名和类型自动识别。如果指定的文件中列的个数不一致，LakeHouse 会尝试合并，无法合并则会报错。
+  ```
+  --指定volume中的列类型和名字
+  COPY OVERWRITE birds FROM 
+  VOLUME  my_volume(id int,name string,wingspan_cm float,colors string)
+  USING csv
+  SUBDIRECTORY 'dau_unload/read/';
+  --自动探查volume中的列类型和名字
+  COPY OVERWRITE birds FROM 
+  VOLUME  my_volume
+  USING csv
+  SUBDIRECTORY 'dau_unload/read/';
+  ```
+* **FileFormatParams**：多个参数使用逗号分隔，字符串形式的'key'='value'
+    * CSV 格式：支持以下文件参数组合
+      * sep：列分隔符，默认为 ”,“。最多支持长度为 2 的字符，例如：`'sep'=','`、`sep='||'`或者`sep = '\001'`：使用 Hive 默认的字段分隔符（不可见字符）
+      * compression：配置文件压缩格式。支持的压缩格式有：gzip/zstd/zlib。例如：`'compression'='gzip'`
+      * lineSep：行分隔符，默认会将 `\r\n` 与 `\n` 都识别为换行。最多支持长度为 2 的字符，例如：`'lineSep'='$'`使用 `$` 作为行分隔符。`lineSep = '\r\n'`使用 Windows 风格的换行符
+      * quote：用于包裹包含特殊字符的字段内容，避免解析错误。默认值为双引号 "，当字段内容包含默认引用符（"）时必须指定。
+        例如：导入数据为 `{"key":"value"}` 这类含双引号的 JSON 字符串时，需改用其他字符包裹，例如指定 `quote = r'\0'`，空字符`\0`方案需确保数据中不存在该字符。
+      * header：是否解析表头，默认为 false。布尔类型，例如：`'header'='true'`
+      * timeZone：配置时区，没有默认值。用于指定文件中时间格式的时区。例如：`'timeZone' = 'Asia/Shanghai'`
+      * escape：用于转义已加引号的值中的特殊字符，仅支持单字节字符。默认值为”\“，例如：`'escape'=r'\'`。转义字符用于解释数据文件中字段分隔符或换行符的特殊含义。如果某一行以反斜杠结尾，则该反斜杠会转义文件格式选项中指定的换行符或回车符（`lineSep`）。因此，加载操作会将此行和下一行视为一行数据。如果不需要这种转义行为，可以将转义字符设置为其他字符
+      * nullValue: 用于判定什么样的内容应该被视为 Null，默认值为 \`""\`，例如 \`'nullValue'='\\\N'\` 或者 \`'nullValue'=r'\N'\`。为了避免在不确定何时需要转义的情况下手动处理转义字符，Lakehouse 支持在字符串前添加 `r` 前缀，表示字符串中的转义字符不会被转义，可以直接输入到表达式中运行。
+       * multiLine: 是否有跨行的 csv 记录，默认值为 `false`，如果有这样的记录，需要配置 `multiLine='true'`
+    
+    
+    ```
+    --指定分隔符和quote
+    COPY OVERWRITE birds FROM 
+    VOLUME  my_volume
+    USING csv
+    OPTIONS('sep'='|','quote'='"')
+    files('dau_unload/part00001.csv');
+    ```
+    
+    * JSON格式:
+      * compression: 源文件/目标文件是否压缩，默认不压缩，配置如 `'compression'='gzip'`
+      ```
+      --导入json数据
+      COPY OVERWRITE birds FROM 
+      VOLUME  my_volume
+      USING json
+      files('dau_unload/part00001.json');
+      ```
+        * explodeArray：默认值 true， 可选值 false。在 JSON 内容是数组开头时使用。为 true 时认为 schema 是数组内单个元素的 schema，为 false 时认为 schema 是数组本身的 schema。
+    * Parquet , ORC , BSON 格式
+    * ```
+      --导入parquet数据
+      COPY OVERWRITE birds FROM 
+      VOLUME  my_volume
+      USING parquet
+      files('dau_unload/part00001.parquet');
+      ```
+
+* **FILES**：用于指定要读取的具体文件。支持指定多个相同格式的文件。文件路径为创建 Volume 时指定的子文件路径。` `例如：`files('part-00002.snappy.parquet','part-00003.snappy.parquet')`。
+* **SUBDIRECTORY**：指定子路径。用于指定要读取的子路径。读取时会递归地加载该目录下的所有文件。例如：`subdirectory 'month=02'。`
+* ```
+  COPY OVERWRITE birds FROM 
+  VOLUME  my_volume(id int,name string,wingspan_cm float,colors string)
+  USING csv
+  SUBDIRECTORY 'dau_unload/read/';
+  ```
+* **REGEXP**\<pattern>：正则表达式匹配。正则路径匹配基于url，您可通过`SHOW VOLUME DIRECTORY my_tx_volume;`命令查看url。例如，`regexp 'part-.*.parquet'`可匹配以“part-”开头且以“.parquet”结尾的文件。需要注意的是，正则表达式匹配的目标是文件的**完整的对象存储路径**（如 's3://cz-udf-user/volume-data/1234321.csv.gz'），而不是文件在 Volume 对象中的相对路径。
+
+* **PURGE=TRUE**：当设置此参数时，表示在数据导入成功后，将删除对象存储中的源文件。这有助于节省存储空间，特别是在处理大量数据时。如果导入操作失败，源文件将不会被删除。
+* **ON_ERROR=CONTINUE|ABORT**:控制当数据加载过程中遇到错误时的处理策略。添加此参数后，会返回导入文件列表。
+  * `CONTINUE`：跳过错误行，继续加载后续数据。使用场景：容忍部分错误，要求最大限度完成数据加载。目前忽略的错误只支持文件格式不匹配，例如命令中指定的是 zip 压缩格式但文件中实际是 zstd 压缩。
+  * `ABORT`：立即终止整个 COPY 操作。使用场景：严格数据质量要求场景，任何错误都需人工介入检查

+
+# 注意事项
+
+* 导入数据时建议您选择通用型计算集群(GENERAL PURPOSE VIRTUAL CLUSTER),通用型计算资源更加适合跑批量作业和加载数据作业
+* 建议导入数据时选择同一个 Region，这样可以避免公网传输费用。在同一个 Region 且同一个云厂商内，数据传输通过内网进行。
+
+# 具体案例
+
+1.从user volume中加载数据
+
+```SQL
+--创建表
+CREATE TABLE birds (
+    id INT,
+    name VARCHAR(50),
+    wingspan_cm FLOAT,
+    colors STRING
+);
+--将数据上传到user volume中
+PUT '/Users/Downloads/data.csv' TO USER VOLUME FILE 'data.csv';
+--导入文件数据至目标表
+COPY INTO t_copy_from_volume FROM USER VOLUME  
+USING csv  
+OPTIONS(
+        'header'='true',
+        'lineSep'='\n'
+)
+FILES ('data.csv')
+--删除volume中的文件，节省存储
+PURGE=TRUE;
+;
+```
+
+2.从table volume中加载数据
+
+```SQL
+CREATE TABLE birds (
+    id INT,
+    name VARCHAR(50),
+    wingspan_cm FLOAT,
+    colors STRING
+);
+--将数据上传到table volume中
+PUT '/Users/Downloads/data.csv' TO TABLE VOLUME t_copy_from_volume FILE 'data.csv';
+--导入文件数据至目标表
+COPY INTO t_copy_from_volume FROM TABLE VOLUME t_copy_from_volume
+USING csv  
+OPTIONS(
+        'header'='true',
+        'lineSep'='\n'
+)
+FILES ('data.csv')
+--删除volume中的文件，节省存储
+PURGE=TRUE;
+;
+
+```
+
+导出到外部 VOLUME 中使用，前提是需要创建 VOLUME 和 CONNECTION。创建过程可以参考 [CONNECTION创建](Datalake_StorageConnection.md) 和 [VOLUME创建](datalake_volume_object.md)。
+
+3.将数据从oss中导入
+
+```SQL
+--创建表
+CREATE TABLE birds (
+    id INT,
+    name VARCHAR(50),
+    wingspan_cm FLOAT,
+    colors STRING
+);
+--创建oss conenction
+CREATE STORAGE CONNECTION  catalog_storage_oss
+    type OSS
+    ACCESS_ID='xxxx'
+    ACCESS_KEY='xxxxxxx'
+    ENDPOINT='oss-cn-hangzhou-internal.aliyuncs.com';
+--创建volume
+CREATE EXTERNAL VOLUME my_volume
+    location 'oss://mybucket/test_insert/'
+    using connection catalog_storage_oss
+    directory = (
+        enable=true,
+        auto_refresh=true
+    );
+--将数据如到表中
+COPY INTO birds FROM 
+VOLUME  my_volume
+USING csv
+SUBDIRECTORY 'dau_unload/read/';
+
+```
+
+4.将数据从cos中导入
+
+```
+--创建表
+CREATE TABLE birds (
+    id INT,
+    name VARCHAR(50),
+    wingspan_cm FLOAT,
+    colors STRING
+);
+--创建cos conenction
+CREATE STORAGE CONNECTION my_conn 
+  TYPE COS
+  ACCESS_KEY = '<access_key>'
+  SECRET_KEY = '<secret_key>'
+  REGION = 'ap-shanghai'
+  APP_ID = '1310000503';
+--创建volume
+CREATE EXTERNAL VOLUME my_volume
+    location 'cos://mybucket/test_insert/'
+    using connection my_conn
+    directory = (
+        enable=true,
+        auto_refresh=true
+    );
+--将数据导入到表中
+COPY INTO birds FROM 
+VOLUME  my_volume
+USING csv
+SUBDIRECTORY 'dau_unload/read/';
+
+```
+
+5.将数据从s3中导入
+
+```SQL
+--创建表
+CREATE TABLE birds (
+    id INT,
+    name VARCHAR(50),
+    wingspan_cm FLOAT,
+    colors STRING
+);
+
+--创建s3 conenction
+CREATE STORAGE CONNECTION aws_bj_conn
+    TYPE S3
+    ACCESS_KEY = 'AKIAQNBSBP6EIJE33***'
+    SECRET_KEY = '7kfheDrmq***************************'
+    ENDPOINT = 's3.cn-north-1.amazonaws.com.cn'
+    REGION = 'cn-north-1';
+--创建volume
+CREATE EXTERNAL VOLUME my_volume
+    location 's3://mybucket/test_insert/'
+    using connection aws_bj_conn
+    directory = (
+        enable=true,
+        auto_refresh=true
+    );
+--将数据导入到表中
+COPY INTO birds FROM 
+VOLUME  my_volume
+USING csv
+SUBDIRECTORY 'dau_unload/read/';
+```
+
+
+6. 导入 CSV 文件，并使用 JSON 函数解析，导入到 JSON 表中
+
+```SQL
+CREATE  TABLE pipe_json_load(col JSON);
+COPY INTO pipe_json_load FROM(
+SELECT parse_json(col)
+FROM  VOLUME 
+hz_csv_volume(
+col
+)
+USING csv 
+OPTIONS ('header' = 'false')
+);
+```
+
+7. 导入过程中使用SQL和维度表做join。过滤需要导入的数据
+
+```
+--部分数据如下
+create table departments (
+  dept_id int ,
+  dept_name varchar,
+  location varchar
+);
+insert into departments values
+(10, '销售部', '北京'),
+(20, '研发部', '上海'),
+(30, '财务部', '广州'),
+(40, '人事部', '深圳');
+--员工表如下
+CREATE  TABLE employees (
+          emp_id int,
+          emp_name varchar,
+          dept_id int,
+          salary int
+);
+--在volume中存储的数据如下
+10,"销售部","北京",
+20,"研发部","上海",
+30,"财务部","广州",
+40,"人事部","深圳",
+--要求只导入销售部的数据
+COPY OVERWRITE employees FROM 
+(SELECT f0::int,f1,f2::int,f3::int FROM 
+VOLUME  my_volume
+USING csv
+files('dau_unload/employees/part00001.csv') 
+join
+departments   
+on f3=dept_id
+where dept_name='销售部'
+);
+```
+
+8.导入Parquet文件并且使用正则匹配对应的文件
+
+```SQL
+COPY INTO hz_parquet_table
+FROM VOLUME hz_parquet_volume
+USING parquet 
+REGEXP 'month=0[1-5].*.parquet';
+```
+
+9.导入BSON文件
+
+```SQL
+--LOAD FROM VOLUME USING BSON FORMAT
+COPY INTO t_bson 
+FROM VOLUME my_external_vol(
+        name string, 
+        age bigint, 
+        city string, 
+        interests array<string>
+)
+USING BSON
+FILES( 'data.bson');
+```

+# 创建腾讯云存储连接
+
+本步骤的目标是：允许 Lakehouse 集群访问腾讯上的对象存储 COS。为了完成这个目标，可以通过腾讯云**访问管理**提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
+
+## 基于访问密钥
+
+```sql
+CREATE STORAGE CONNECTION my_conn 
+  TYPE COS
+  ACCESS_KEY = '<access_key>'
+  SECRET_KEY = '<secret_key>'
+  REGION = 'ap-shanghai'
+  APP_ID = '1310000503';
+```
+
+### 参数：
+
+* **TYPE**：为对象存储类型，腾讯云应填写 `COS`（大小写不限）
+
+* **ACCESS\_KEY / SECRET\_KEY**：为腾讯云的访问密钥，获取方式参考：[访问密钥](https://cloud.tencent.com/document/product/598/40488)
+
+* **REGION**：指腾讯云对象存储 COS 的数据中心所在的地域。相同地域内云器Lakehouse访问腾讯云COS时，COS服务将自动路由至内网访问。具体取值请参考腾讯云文档：[地域和访问域名](https://cloud.tencent.com/document/product/436/6224)。
+
+* **APP\_ID**：腾讯云存储桶的命名由存储桶名称（BucketName）和 APPID 两部分组成，两者以中划线“-”相连。例如 `examplebucket-1310000503`，其中 `examplebucket` 为用户自定义，`1310000503` 为系统生成数字串（APPID）。
+
+## 基于角色授权
+
+### STEP1: 数据创建权限策略 (LakehouseAccess )：
+
+* 登录腾讯云，进入**访问管理**产品控制台
+* 在**访问管理**页面左侧导航栏进入**策略**，在权限控制界面选择 **新建自定义策略** -> **按策略生成器创建** -> **可视化策略生成器**。
+* 在**可视化策略生成器**页签中：**服务**（**Service**）: 选择 **对象存储(cos**)；**操作（Action**）：选择**全部操作**（可根据实际需要的操作，做更细粒度的选择）；**资源（Resource**）：根据需要选择**全部资源**或者**特定资源**。本示例中选择特定资源，为上海区的` cz-volume-sh-1311343935`![](.topwrite/assets/20240625-211734.jpeg)
+* 点击**下一步**，填写**策略名称**为 LakehouseAccess 和描述后，点击**完成**
+
+### STEP2：客户侧创建角色（LakehouseRole）
+
+* 进入腾讯云**访问管理**产品控制台
+* 在**访问管理**页面左侧导航栏进入**角色** -> **新建角色** -> **腾讯云账户**， 选择**其他主账号**，在 **账号ID** 中输入 `100029595716`（云器的腾讯云主账号），其它选项保持默认，点击**下一步**
+* 在**配置角色策略**配置中，将刚才新建的 LakehouseAccess 自定义策略授权给当前角色。点**击下一步**，在**角色命名**中填写 `LakehouseRole `完成创建。
+* 创建成功后，在角色列表中，进入角色 `LakehouseRole` 的详情页，获取该角色的 RoleARN 信息：  `qcs::cam::uin/1000*******:roleName/LakehouseRole`
+
+### STEP3：Lakehouse 侧创建 Connection
+
+* 在 Studio 或者 Lakehouse JDBC 客户端中执行以下命令：
+
+```
+CREATE STORAGE CONNECTION my_tx_connection_arn
+   TYPE cos
+   REGION = 'ap-shanghai'
+   ROLE_ARN = 'qcs::cam::uin/1000********:roleName/LakehouseRole'
+   APP_ID = '131****35';
+```
+
+^
+
+> 注意：为了防止 ROLE\_ARN 被第三方获取进行未授权的数据访问，可以使用` EXTENRAL ID` 作为一种额外的验证层，确保只有当请求中包含了预设的 `EXTERNAL ID` 时，这一访问才会被允许。这意味着即使第三方知道了其他一些访问信息（如角色ARN），没有正确的 `EXTERNAL ID` 也无法访问资源。
+
+* 在创建存储连接的过程中，Lakehouse 会生成此EXTERNAL ID，可以将此EXTERNAL ID 配置到 COS 账号的角色校验中实现访问控制：
+
+```
+-- 查看 EXTERNAL ID 
+DESC CONNECITON my_tx_connection_arn ;
+```
+
+![](.topwrite/assets/20240625-214538.jpeg)
+
+^
+
+* 客户侧：进入腾讯云**访问管理**控制台中，**角色** -> **LakehouseRole** -> **角色载体**-> **管理载体**，选择 **添加账户** -> 选择**当前主账号**，并填写主账号ID：`100029595716`（云器的腾讯云主账号），并勾选**开启校验**，输入刚才 DESC 结果中的 EXTERNAL\_ID，点击 **确定**-> **更新**

+## 案例说明
+
+API CONNECTION 主要应用于 EXTERNAL FUNCTION 的创建。EXTERNAL FUNCTION 的使用如下过程
+
+* 用户开通云上的函数计算服务（如阿里云的函数计算FC）和对象存储服务
+* 将函数执行代码 & 可执行文件、依赖的库、模型和数据文件，打包上传至对象存储
+* 并且授予云器 Lakehouse 操作上述服务和访问函数文件的权限
+* 用户在云器 Lakehouse SQL 语句中调用 EXTERNAL FUNCTION
+* 云器 Lakehouse 根据提供的服务地址和认证信息发送 http 请求调用运行函数
+* 云器 Lakehouse 获取响应信息返回结果
+  因此您必须开通函数计算服务和对象存储服务。并且授权给云器 Lakehouse 权限
+
+### 阿里云创建API CONNECTION
+
+* **环境准备**
+  EXTERNAL FUNCTION 依赖阿里云的 "[对象存储](https://oss.console.aliyun.com/overview)" 和 "[函数计算](https://fcnext.console.aliyun.com/overview)" 服务, 请确保相关服务已开通
+
+* 步骤1: 用户开通云上的函数计算服务（如阿里云的函数计算FC）和对象存储服务
+
+* 步骤2.  阿里云侧操作：在阿里云 RAM 控制台中创建权限策略 (CzUdfOssAccess )：注意：需要用户具有RAM权限
+  * 访问阿里云访问控制（RAM）[产品控制台](https://ram.console.aliyun.com/policies)
+  * 左侧导航栏 **权限管理** -> **权限策略**，在权限控制界面选择 搜索**AliyunFCFullAccess**->编辑 **AliyunFCFullAccess** 权限策略 添加下面"acs\*\*:**Service**": "**fc.aliyuncs.com**"\*\*部分
+    ```JSON
+    {
+        "Version": "1",
+        "Statement": [
+            {

+                }
+            }
+        ]
+    }
+    ```
+
+* 步骤3:在阿里云 RAM 控制台中创建权限策略 (CzUdfOssAccess )：注意：需要用户具有RAM权限
+
+  * 访问阿里云访问控制（RAM）产品控制台
+  * 左侧导航栏 **权限管理** -> **权限策略**，在权限控制界面选择 **创建权限策略**
+  * 在**创建权限策略**页面选择 **脚本编辑** 的页签，将下面`  [bucket_name_1|2|3]  `替换为实际的 OSS bucket 名称。注意：按照阿里云OSS 的约定，相同的bucket 需要有两条Resource条目：`"acs:oss:*:*:bucket_name_1" `与 `"acs:oss:*:*:bucket_name_1/*"`同时存在才能达到授权效果：
+
+  ```JSON
+  {
+      "Version": "1",
+      "Statement": [
+          {
+              "Effect": "Allow",

+              ]
+          }
+      ]
+  }
+  ```
+
+* 步骤4： 阿里云控制台：在阿里云 RAM 中创建角色（如：CzUDFRole）：
+  * 在RAM 控制台左侧导航栏 **身份管理** -> **角色**，点击**创建角色**
+  * 在 **创建角色** 页面中，选择类型为 **阿里云账号**， 配置角色中填写自定义**角色名称 如** (CzUDFRole)，在**选择信任的云账号** 中选择 **其他云账号**，并写入：1384322691904283（云器 Lakehouse 上海的云主账号），点击**完成**
+  * 创建完成之后，点击**为角色授权**:
+  * 在**系统策略**中，将 **AliyunFCFullAccess** 策略授权给该角色 CzUDFRole
+  * 在**自定义策略**中，将刚创建的策略（**CzUdfOssAccess**）授权给该角色
+
+* 步骤5： 创建完成之后，点击**为角色授权**: 在**自定义策略**中，将刚创建的策略（CzUdfOssAccess）授权给该角色。在角色 CzUDFRole 详情页中，获取该角色的 RoleARN 信息：`'acs:ram::1222808864xxxxxxx:role/czudfrole'`![](.topwrite/assets/20231113-153016.jpeg)
+
+* 步骤6：将上面的role\_arn填入到语法参数重，创建阿里云函数计算连接
+
+```SQL
+CREATE API CONNECTION my_funciton_connection
+TYPE CLOUD_FUNCTION
+PROVIDER='aliyun'
+REGION='cn-hangzhou'
+ROLE_ARN='acs:ram::1757168149572678:role/czudfrole'
+CODE_BUCKET='function-compute-my1';
+```
+
+* 步骤7: desc connection 获取 external ID 信息：本实例中，external ID 为：`VW9UaGwYENBQ7cFp`
+  ```
+  DESC CONNECTION my_funciton_connection;
+  ```
+  ![](.topwrite/assets/image_1735638011131.png)
+  * 在阿里云 RAM -> 角色->  信任策略中，修改 CzUDFRole 的**信任策略** `"sts:ExternalId"` 部分：

+EXTERNAL FUNCTION 依赖腾讯云的 "[对象存储](https://console.cloud.tencent.com/cos)" 和 "[云函数](https://console.cloud.tencent.com/scf/list?rid=1\&ns=default)" 服务, 请确保相关服务已开通.
+
+* 对象存储：需要在云器 Lakehouse 部署地域 (例如 ap-shanghai) 用于存放函数基础代码;
+* 云函数：**云函数** 服务开通后, 建议使用模板创建功能手动创建一个函数, 推荐使用Flask 框架模板等带有WebFunc标签的模板; 在此过程中, 腾讯云控制台 会引导用户完成一些初始化配置, 例如开通日志服务 (CLS) 等依赖服务, 创建必要 访问控制 (CAM) 角色, 授予必要 访问控制 (CAM) 权限等.
+* 步骤1: 用户开通腾讯云的云函数计算服务。云函数 region 保持和云器 Lakehouse开服区域一致
+  ![](.topwrite/assets/image_1735616566747.png)
+* 步骤2: 数据创建权限策略 (LakehouseAccess )：
+
+  * 登录腾讯云，进入**访问管理**[产品控制台](https://console.cloud.tencent.com/cam/policy)
+  * 在**访问管理**页面左侧导航栏进入**策略**，在权限控制界面选择 **新建自定义策略** -> **按策略生成器创建** -> **可视化策略生成器**。
+  * 在**可视化策略生成器**页签中**服务**（**Service**）: 选择**云函数**；**操作（Action**）：选择**全部操作**（可根据实际需要的操作，做更细粒度的选择）；**资源（Resource**）：根据需要选择**全部资源**或者**特定资源**。本次案例选择为特定资源,使用 namespace 授权如下图，点击编辑按钮，选择**步骤1**中的开通region,资源可以是\*也可以指定namespace，本次案例为中的命名空间：default。如图二中云函数红色标记的位置![](.topwrite/assets/image_1735629287184.png)

+* Databricks Unity Catalog：Unity Catalog 是 Databricks 上数据和 AI 资产的统一治理解决方案。在 Unity Catalog 中，所有元数据都注册在元存储中。任何 Unity Catalog 元存储中的数据库对象层次结构都分为三个级别，当您引用表、视图、卷、模型和函数时，它们表示为三级命名空间。通过连接 Databricks 的 Unity Catalog，Lakehouse 可以自动获取 Databricks 的库表信息，并进行数据查询。
+* 要求必须和 Lakehouse 所在的存储位置在同一云平台。例如，如果 Lakehouse 在 AWS，则 Databricks 存储须在 S3。
+
+# 创建Hive Catalog语法
+
+```SQL
+CREATE CATALOG CONNECTION if not exists connection_name
+    type hms
+    hive_metastore_uris='metastore_uris'
+    storage_connection='storage_connection';
+```
+
+**参数说明**
+
+* **connection\_name**: 连接的名称，需保证唯一性。
+* **type**: 连接类型，此处为 `hms`（Hive Metastore Service）。
+* **hive\_metastore\_uris**: Hive Metastore 的服务地址，格式为 `host:port`。port（端口）通常是 9083。

+# 创建 Databricks Unity Catalog 连接
+
+***
+
+## **概述**
+
+本文档详细说明如何使用 SQL 语句创建 Databricks Unity Catalog 连接。通过该连接，用户可以将外部系统与 Databricks Unity Catalog 集成，实现数据管理和共享。本文档涵盖语法、参数说明及配置要求。
+
+***
+
+## **语法**
+
+```SQL
+CREATE CATALOG CONNECTION IF NOT EXISTS <CONNECTION_NAME>
+    TYPE databricks
+    HOST = 'host_value'
+    CLIENT_ID = 'client_id_value'
+    CLIENT_SECRET = 'client_secret_value'
+    ACCESS_REGION = 'access_region_value';
+```
+
+**参数说明**
+
+* `CONNECTION_NAME`：连接的名称，用于标识该 Databricks Unity Catalog 连接。名称需唯一且符合命名规范。
+* `TYPE`：指定连接类型为 Databricks Unity Catalog。
+* `HOST`： Databricks 工作区的 URL 地址。通常格式为 `https://<workspace-url>`。  示例：`https://dbc-12345678-9abc.cloud.databricks.com`
+* `CLIENT_ID / CLIENT_SECRET`: 用于 OAuth 2.0 机器对机器（M2M）认证的客户端 ID。参考 [Databricks OAuth M2M 认证文档](https://docs.databricks.com/en/dev-tools/auth/oauth-m2m.html) 创建 OAuth 2.0 应用，并获取 `CLIENT_ID `和` CLIENT_SECRET`
+* `ACCESS_REGION`：Databricks 工作区所在的区域（Region），例如 `us-west-2` 或 us-east-1。
+
+## **示例**
+
+**Step 1：Databricks 准备**
+
+1. 创建 service principal 参考[Databricks文档](https://docs.databricks.com/en/dev-tools/auth/oauth-m2m.html#language-Java)获取 principal 及其 client id/client secret
+2. Metastore 开启 external data access
+   ![](.topwrite/assets/image_1739256232288.png)
+   ![](.topwrite/assets/image_1739256275537.png)
+3. 授权 service principal
+
+```SQL
+--使用 service principal 的 id
+GRANT EXTERNAL USE SCHEMA ON SCHEMA quick_start.default TO `cf752cce-e2ca-4d03-8cdc-9f8f8aac43fc`;
+
+```
+
+以下是一个完整的示例，展示如何创建 Databricks Unity Catalog 连接：
+
+```SQL
+CREATE CATALOG CONNECTION IF NOT EXISTS my_databricks_conn
+    TYPE databricks
+    HOST = 'https://dbc-12345678-9abc.cloud.databricks.com'
+    CLIENT_ID = '12345678-9abc-def0-1234-56789abcdef0'
+    CLIENT_SECRET = 'abcdef1234567890abcdef1234567890'
+    ACCESS_REGION = 'us-west-2';
+```
+
+**Step 2：Lakehouse**
+以下是一个完整的示例，展示如何创建 Databricks Unity Catalog 连接：
+
+```SQL
+CREATE CATALOG CONNECTION IF NOT EXISTS my_databricks_conn    
+ TYPE databricks   
+ HOST = 'https://dbc-12345678-9abc.cloud.databricks.com'    
+ CLIENT_ID = '12345678-9abc-def0-1234-56789abcdef0' 
+ CLIENT_SECRET = 'abcdef1234567890abcdef1234567890' 
+ ACCESS_REGION = 'us-west-2';
+```
+
+**常见问题**
+
+Q1: 如何验证连接是否成功?
+
+* 创建连接后，可通过查询 Catalog下的Schema 或表数据验证连接状态。
+* 示例：
+
+  ```SQL
+    CREATE EXTERNAL CATALOG external_db_cat
+    CONNECTION my_databricks_conn
+    OPTIONS ('catalog'='quick_start');
+    show schemas in external_db_cat;
+    select * from external_db_cat.default.student;
+  ```
+
+Q2：连接失败的可能原因有哪些？
+
+* `HOST` 地址错误或不可访问。

+# 创建动态表（Dynamic Table）
+
+## 功能
+
+动态表（Dynamic Table）是一种特殊的表，它可以实时地根据查询语句来更新数据。动态表可以让您更加灵活地处理数据，提高查询效率。更多使用方式参考[动态表介绍](dynamic-table-introduce.md)和[增量计算部分](dynamic-table.md)
+
+## 普通动态表创建语法
+
+```SQL
+
+CREATE [ OR REPLACE | IF NOT EXISTS ] DYNAMIC TABLE dtname
+[ (column_list ) ]
+[PARTITIONED BY (column_name) ]
+[CLUSTERED BY (column_name)]
+[COMMENT view_comment]
+[PROPERTIES('data_lifecycle'='day_num')];
+[refreshOption]
+AS <query>;  
+
+refreshOption ::=
+    REFRESH 
+    [START WITH timestamp_expr]  [interval_time] VCLUSTER vcname
+```
+
+**必需参数**
+
+1. dtname: 指定动态表名称。
+2. AS query：动态表所包含的查询语句。
+
+**可选参数**
+
+1. IF NOT EXISTS:可选，如果指定的物化视图名字存在，系统不会报错，但是物化视图不会创建成功。不能和OR REPLACE同时使用
+
+2. OR REPLACE:在传统数据库中，此选项用于在同一个事务内用新对象替换旧对象，并删除旧对象的数据。但在Lakehouse中，为了支持动态表（Dynamic Table）的增加、删除和修改操作，我们保留了数据以及元数据权限信息。这意味着，即使在修改表结构或SQL逻辑时，原有数据也不会丢失。此功能特别适用于添加或删除列、调整SQL处理逻辑以及变更数据类型。需要注意的是如果用户不是简单的 删除列 / 添加列
+   添加列定义：只能是从表一路经由SELECT透传的，不能参与任何会影响其他列的计算例如 join key, group key 等。则在 Create Or Replace 发生后，REFRESH任务会退化为一次全量刷新
+
+   ```

+   ```
+
+3. \<column\_list>：
+   * 可以指定列的名称或者向dynamic table的列添加注释信息，可以指定列的名称无法指定列的类型，类型由 `AS <query>`中的SELECT结果推断而来，如果您希望指定类型可以在SELECT结果中显示CAST转化
+   * 如果表中有任何列是基于表达式，建议为每列提供名称。或者as \<query>中使用别名
+   ```SQL
+     --指定列的comment，当有表达式时建议指定列名字
+   CREATE DYNAMIC TABLE change_table_dy (i, j_dd COMMENT 'test') AS
+   SELECT    i,
+             j + 1
+   FROM      dy_base_a;
+     +-------------+-----------+---------+
+     | column_name | data_type | comment |
+     +-------------+-----------+---------+
+     | i           | int       |         |
+     | j_dd        | int       | test    |
+     +-------------+-----------+---------+
+     --当存在列运算表达式使用别名方式
+   CREATE DYNAMIC TABLE change_table_dy AS
+   SELECT    i,
+             j + 1 AS j_add
+   FROM      dy_base_a;
+     +-------------+-----------+---------+
+     | column_name | data_type | comment |
+     +-------------+-----------+---------+
+     | i           | int       |         |
+     | j_add       | int       |         |
+     +-------------+-----------+---------+
+   ```
+
+4. partitioned by (\<col> ):指定分区，将\<column\_list>的列作为分区，分区是一种通过在写入时将相似的行分组在一起来加快查询速度的方法。使用分区可以达到数据裁剪，优化查询
+
+   ```SQL
+   CREATE DYNAMIC TABLE change_table_dy (i, j_dd COMMENT 'test') PARTITIONED BY (j_dd) AS
+   SELECT    i,
+             j + 1
+   FROM      dy_base_a;
+   ```
+
+4.CLUSTERED BY：可选，指定Hash Key。Lakehouse将对指定列进行Hash运算，将数据根据Hash值分散到各个数据分桶中。为了避免数据倾斜和热点，并提高并行执行效果，建议选择取值范围大、重复键值少的列作为Hash Key。通常在进行join操作时会有明显效果。建议在数据量大的场景下使用CLUSTERED BY，一般按照一个桶的大小在128MB到1GB之间。如果没有指定分桶，默认为256个buckets。
+
+* SORTED BY：可选，指定Bucket内字段的排序方式。建议SORTED BY和CLUSTERED BY保持一致，以获得更好的性能。当指定SORTED BY子句后，行数据将按照指定的列进行排序。
+  ```SQL
+  --创建分桶表
+  CREATE DYNAMIC TABLE change_table_dy (i, j_dd COMMENT 'test') 
+  CLUSTERED BY (j_dd) INTO 16 BUCKETS AS
+  SELECT    i,
+            j + 1
+  FROM      dy_base_a;
+  --创建分桶并指定排序
+  CREATE DYNAMIC TABLE change_table_dy
+  (i, j_dd COMMENT 'test')
+  CLUSTERED BY (j_dd) SORTED BY (j_dd)  INTO 16 BUCKETS  
+  AS
+  SELECT    i,
+            j + 1
+  FROM      dy_base_a;
+  ```
+
+5. comment:指定动态的注释信息
+
+6. refreshOption可选，刷新选项
+   * START WITH timestamp\_exp 指定开始时间，支持指定一个时间戳表达式，如果不写 START WITH 则从当前时间开始刷新
+     * `timestamp_expression`返回结果是一个标准的时间戳类型的表达式，TIMESTAMP AS OF指定的最早时间戳取决[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。如果未指定则使用当前时间戳的版本数据，例如：
+       \* `'2023-11-07 14:49:18'`，即可以强制转换为时间戳的字符串。
+       \* `cast('2023-11-07 14:49:18 Asia/Shanghai' as timestamp)`。
+       \* `current_timestamp() - interval '12' hours`。
+       \* 本身就是时间戳或可强制转换为时间戳的任何其他表达式。
+     ```
+     --指定第二天开始刷新,刷新时间间隔20个小时
+     CREATE DYNAMIC TABLE mydt (i, j)
+     REFRESH   START
+     WITH      current_timestamp() + INTERVAL '1' DAY INTERVAL '20' HOUR vcluster test_alter AS
+     SELECT    *
+     FROM      dy_base_a;
+     ```
+   * interval\_time指定时间间隔，支持[时间间隔类型interval](INTERVAL.md)，如果不写interval\_time，写了 START WITH 则只定时刷新一次START WITH 指定的时间。interval\_time时间间隔如下

+day：取值范围为\[0, 2147483647]。 hour：取值范围为\[0, 23]。minute：取值范围为\[0, 59]。second：取值范围为\[0, 59.999999999]。
+
+* INTERVAL最小值是1分钟，可以用 60 SECOND 或者1 MINUTE 来表示
+  * INTERVAL支持带引号或者不带引号，以下表示是等价的：
+    \*  INTERVAL "60 SECOND"
+    \*  INTERVAL ‘60 SECOND’
+    \* INTERVAL 60 SECOND
+  * INTERVAL支持的单位：SECOND，MINUTE，HOUR，DAY
+  * INTERVAL单位不区分大小写，HOUR、hour是等价的
+
+* 在 `refreshOption` 中指定计算集群。自动刷新会消耗资源，因此需要明确指定计算集群。如果未指定，将默认使用当前会话的计算集群。您可以通过 `SELECT current_vcluster()` 查看当前会话的计算集群。
+
+  * 建议使用GP型集群来刷新动态表。原因：动态表刷新过程中会根据内置策略自动执行小文件合并操作，而AP型集群不支持此功能。
+
+  ```SQL
+  CREATE DYNAMIC TABLE mydt (i, j)
+  REFRESH   interval '1' MINUTE vcluster test AS
+  SELECT    *
+  FROM      dy_base_a;
+  ```
+
+### 注意事项
+
+* 动态表的增量刷新是基于基表的历史版本。历史版本取决于[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。此参数定义了在被删除数据被保留的时间长度，Lakehouse默认保留数据一天。根据您的业务需求，您可以通过调整 `data_retention_days` 参数来延长或缩短数据的保留周期。请注意，调整数据保留周期可能会影响存储成本。延长保留周期会增加存储需求，从而可能增加相关的费用。
+
+# Dynamic Table 支持参数化定义
+
+Dynamic Table 支持参数化定义由两部分组成。
+
+* 创建分区动态表时参数定义SESSION\_CONFIGS()\['dt.args.event\_day']。用于写在SQL加工逻辑中，参数通过 SESSION\_CONFIGS()\['dt.args.xx'] 进行定义,表示查询源表。SESSION\_CONFIGS()是系统内置函数`'dt.args.xx'`：DT参数的名称，必须以`dt.args.`开头，以避免与系统内部字段冲突。表达的含义和传统调度中select \* from source\_table where pt=${bizdate}。`SESSION_CONFIGS()['dt.args.pt']`等价于`pt=${bizdate}`，SESSION\_CONFIGS()\['dt.args.xx'] 返回值类型为 String如果需要其它类型的参数，需要加一个CAST，例如 cast(SESSION\_CONFIGS()\['dt.args.xx'] as int)。如下案例：
+
+```sql
+--源表
+CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
+
+--定义动态表
+CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
+SELECT    col1,
+          nvl(col2, col1),
+          pt
+FROM      source_table
+WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
+```
+
+* 刷新时通过refresh dynamic table targe\_table partition(pt=${bizdate});指定分区值，其中pt=${bizdate}。对应于传统的insert ovewrite targe\_table partition(pt=${bizdate})
+
+```sql
+--上面中定义的动态表分区字段是pt。因此刷新时传入pt=${bizdate}。这里假定bizdate是2024-11-13。刷新时应该使用如下语法
+--将2024-11-13传入到创建语句时的SESSION_CONFIGS()['dt.args.pt']中，替换为2024-11-13用于过滤source_table中的数据
+SET dt.args.pt = 2024 -11 -13;
+--刷新时指定pt=2024-11-13表示写入到动态表的2024-11-13分区中
+REFRESH   dynamic TABLE targe_table PARTITION (pt = '2024-11-13');
+```
+
+## 全量刷新与增量刷新
+
+### 全量刷新
+
+全量刷新发生在以下情况：
+
+1. **非分区表**：
+
+   * 如果在非分区表中使用了参数 `SESSION_CONFIGS()['dt.args.event_day']`，系统会根据参数值的变化决定刷新方式。
+   * 如果参数值保持不变，系统将执行**增量刷新**。
+   * 如果参数值发生变化，系统将执行**全量刷新**，因为参数值的变化等同于改变了表的定义。
+
+2. **分区表**：
+
+   * 分区存在，但是当前刷新的参数与上一次刷新的参数不相同，则进行一次全量刷新，因为参数值的变化会导致 SQL 加工逻辑发生变化。
+   * 如果分区不存在（即第一次刷新某个分区），则进行一次全量刷新
+
+```sql
+-- 创建源表
+CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
+
+-- 创建动态表
+CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
+SELECT    col1,
+          nvl(col2, col1),
+          pt
+FROM      source_table
+WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
+
+-- 示例 1：首次设置参数值为 2024-11-14
+SET dt.args.xxx = 1;
+SET dt.args.pt =2024-11-14;
+
+--刷新为全量刷新
+REFRESH   dynamic TABLE incremental_dt PARTITION (pt = '2024-11-14');
+
+
+-- 示例 2：果第一次刷新某个分区，对应的参数是一个值，如果后面相同分区对应的参数发生了改变了，则相当于dt在这个分区的定义被修改了，所以会重新刷新，如下案例
+SET dt.args.xxx = 2;
+SET dt.args.pt = 2024-11-14;
+-- 刷新动态表，指定分区 pt=2024-11-14
+-- 系统会执行全量刷新，因为参数值发生了变化
+REFRESH   dynamic TABLE incremental_dt PARTITION (pt = '2024-11-14');
+```
+
+### 增量刷新
+
+增量刷新发生在以下情况：
+
+* 非分区表的参数值保持不变。
+* 分区表的参数值保持不变，且分区条件未改变。
+
+**示例代码**：
+
+```SQL
+
+-- 创建源表
+CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
+
+-- 定义动态表
+CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
+SELECT    col1,
+          nvl(col2, col1),
+          pt
+FROM      source_table
+WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
+
+-- 示例 1：首次设置参数值为 2024-11-13
+SET dt.args.pt = 2024 -11 -13;
+
+-- 刷新动态表，指定分区 pt=2024-11-13，全量刷新
+REFRESH   dynamic TABLE target_table PARTITION (pt = '2024-11-13');
+
+-- 示例 2：参数值和分区值未变化，再次刷新
+SET dt.args.pt = 2024 -11 -13;
+
+-- 刷新动态表，指定分区 pt=2024-11-13
+-- 系统会继续执行增量刷新
+REFRESH   dynamic TABLE target_table PARTITION (pt = '2024-11-13');
+```
+
+## 刷新语句
+
+参数化定义的Dynamic Table的刷新行为取决于表是否为分区表。
+
+### **非分区表刷新语法**：
+
+```SQL
+REFRESH DYNAMIC TABLE dt;。
+```
+
+* 非分区表的参数值保持不变，会增量刷新。非分区表的参数值发生变化，会全量刷新
+
+### **分区表刷新语法**：
+
+```SQL
+REFRESH DYNAMIC TABLE dt PARTITION partition_spec;
+```
+
+语句刷新分区表时，必须按照表的分区层级顺序指定`partition_spec`。这意味着，如果表按照多个字段进行分区，这些字段需要按照从最高级别到最低级别的顺序被指定。
+
+* 多级分区，partition\_spec 需要根据分区的层级依次指定。例如，如果表有三级分区(day, hour, min)，必须从高到低依次指定，不能跳过某个分区。指定 day hour 是合法的，低级分区可以忽略，不用全声明。指定 day min 是不合法的，因为它跳过了 hour
+
+  * ```SQL
+    --不合法的
+    set dt.args.day = 1;
+    set dt.args.min = 1;
+    REFRESH   dynamic TABLE incremental_dt PARTITION (DAY = 1, MIN = 1);
+
+    --合法的
+    set dt.args.day = 1;
+     set dt.args.hour = 1;
+    REFRESH   dynamic TABLE incremental_dt PARTITION (DAY = 1, HOUR = 1);
+    ```
+
+**示例说明**：
+
+假设一个表按照`day`、`hour`和`min`三级进行分区，正确的`partition_spec`指定方式如下：
+
+* **合法指定**：您可以指定高层级和部分低层级分区，但不可跳过任何中间层级分区。
+
+```SQL
+set dt.args.day=2024-11-13;
+set dt.args.hour=23;
+REFRESH DYNAMIC TABLE dt PARTITION (day='2024-11-13', hour=23); 
+```
+
+在这个例子中，`day`和`hour`被指定，而`min`分区可以被忽略。
+
+* **不合法指定**：跳过任何中间层级分区的指定是不被允许的。
+
+```SQL
+set dt.args.day=2024-11-13
+set dt.args.hour=30
+REFRESH DYNAMIC TABLE dt PARTITION (day='2024-11-13', min=30); 
+```
+
+## **注意事项**
+
+* **参数与分区一致性**：在执行Dynamic Table的刷新操作时，必须确保证SQL计算的分区值与指定刷新的分区值保持一致。如果存在不一致，系统将在执行过程中报错。
+
+```SQL
+CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
+SELECT    col1,
+          nvl(col2, col1),
+          pt
+FROM      source_table
+WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
+
+--比如select col1, nvl(col2, col1), pt from source_table where pt = SESSION_CONFIGS()['dt.args.pt'];过滤出来对应的分区字段结果是9.系统将在执行过程中报错，
+set dt.args.event_day = 9;
+
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 19);
+
+```
+
+* **并发刷新任务**：在这些命令中，参数值与分区值匹配，因此可以并发执行而不会发生冲突。只要分区之间不存在冲突，系统允许同时执行多个分区的刷新任务。
+
+```SQL
+-- 为分区 event_day=19 设置参数并刷新
+set dt.args.event_day = 19;
+
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 19);
+
+-- 为分区 event_day=20 设置参数并刷新
+set dt.args.event_day = 20;
+
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 20);
+```
+
+## 使用案例
+
+* 动态表分区字段和源表中字段一致
+
+```sql
+CREATE TABLE event_tb_pt (
+    event STRING,
+    process DOUBLE,
+    event_time TIMESTAMP
+  );
+INSERT INTO event_tb_pt VALUES
+  ('event-0', 20.0, TIMESTAMP '2024-09-20 14:43:13'),
+  ('event-0', 20.0, TIMESTAMP '2024-09-19 11:40:13'),
+ ('event-1', 20.0, TIMESTAMP '2024-09-19 11:40:13');
+--创建动态表
+CREATE dynamic table  event_gettime_pt 
+partitioned by(event)
+AS SELECT
+  event,
+  process,
+  YEAR(event_time) event_year,
+  MONTH(event_time) event_month,
+  DAY(event_time) event_day
+FROM event_tb_pt
+where event=SESSION_CONFIGS()['dt.args.event'];
+--刷新动态表
+set dt.args.event = event-0;
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event = 'event-0');
+SELECT *FROM event_gettime_pt;
+```
+
+* 动态表分区字段和源表中字段名字不一致。过滤条件需要根据event过滤，动态表分区字段是event\_year
+
+```sql
+DROP      TABLE IF EXISTS event_tb_pt;
+CREATE TABLE event_tb_pt (
+    event STRING,
+    process DOUBLE,
+    event_time TIMESTAMP
+  );

+--刷新动态表
+set dt.args.event = event-0;
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_year = 2024);
+SELECT * FROM  event_gettime_pt;
+```
+
+* 多级分区刷新
+
+```sql

+--多级分区刷新，指定高层级分区
+set dt.args.event = event-0;
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_year = 2024,event_month =9);
+```
+
+### 场景案例
+
+**案例一：将离线任务转换为增量任务**
+本节将指导用户如何将原有的离线任务转换为增量任务，以实现更高效的数据处理。以下是一个基于“传统数据库”的具体操作步骤，适用于业务逻辑按天对齐和按天调度刷新的场景。
+
+* 步骤 1：参数化原始 SQL。原始 SQL如下
+
+  ```sql
+  WITH      tmp_channel AS (
+            SELECT    channel_code,
+                      channel_name,
+                      channel_type,
+                      channel_uid
+            FROM      dim.dim_shop_sales_channel_main
+            WHERE     pt = '${bizdate}'
+            ),
+            tmp_bac_misc AS (
+            SELECT    mini_number,
+                      bac_no
+            FROM      dim.dim_customer_bac_misc_df
+            WHERE     pt = '${bizdate}'
+            ),
+            tmp_fxiaoke AS (
+            SELECT    CASE
+                                WHEN record_type IN ('dealer__c') THEN nvl(bac_no, account_no)
+                                ELSE account_no
+                      END AS channel_code,
+                      id,
+                      account_no
+            FROM      ods.ods_account_obj AS a
+            LEFT JOIN tmp_bac_misc ON a.account_no = tmp_bac_misc.mini_number
+            WHERE     pt = '${bizdate}' AND      
+                      account_no IS NOT NULL
+                      --  and is_deleted = 0
+                      --  and life_status not in ('invalid', 'ineffective')
+            )
+  INSERT    OVERWRITE TABLE dim.dim_shop_sales_channel_misc PARTITION (pt = '${bizdate}')
+  SELECT    tmp_channel.channel_code,
+            channel_name,
+            channel_type,
+            channel_uid,
+            id AS fxiaoke_id,
+            account_no AS fxiaoke_account_no
+  FROM      tmp_channel
+  LEFT JOIN tmp_fxiaoke ON tmp_channel.channel_code = tmp_fxiaoke.channel_code;
+  ```
+
+  首先，需要将原始 SQL 中的所有由调度引擎传入的参数 `${bizdate}` 替换为 `SESSION_CONFIGS()['dt.args.bizdate']`。这一步骤将使得参数值可以通过配置动态传入，而不是硬编码在 SQL 中。
+
+  **原始 SQL 参数替换**:
+  将所有 `${bizdate}` 替换为 `SESSION_CONFIGS()['dt.args.bizdate']`：
+
+  ```sql
+  CREATE dynamic TABLE im.dim_shop_sales_channel_misc
+  PARTITIONED BY (pt)
+  WITH      tmp_channel AS (
+            SELECT    channel_code,
+                      channel_name,
+                      channel_type,
+                      channel_uidfrom dim.dim_shop_sales_channel_main
+            WHERE     pt = SESSION_CONFIGS () ['dt.args.bizdate']
+            ),
+            tmp_bac_misc AS (
+            SELECT    mini_number,
+                      bac_nofrom dim.dim_customer_bac_misc_df
+            WHERE     pt = SESSION_CONFIGS () ['dt.args.bizdate']
+            ), 
+           tmp_fxiaoke AS (    
+            SELECT    CASE
+                                WHEN record_type IN ('dealer__c') THEN nvl(bac_no, account_no)
+                                ELSE account_no
+                      END AS channel_code,
+                      id,
+                      account_no
+            FROM      ods.ods_account_obj AS a
+            LEFT JOIN tmp_bac_misc ON a.account_no = tmp_bac_misc.mini_number
+      WHERE pt = SESSION_CONFIGS()['dt.args.bizdate'] and account_no is not null
+  )
+  SELECT    tmp_channel.channel_code,
+            channel_name,
+            channel_type,
+            channel_uid,
+            id AS fxiaoke_id,
+            account_no AS fxiaoke_account_no,
+            pt
+  FROM      tmp_channel
+  LEFT JOIN tmp_fxiaoke ON tmp_channel.channel_code = tmp_fxiaoke.channel_code
+  ;
+  ```
+
+* 步骤 2：调度刷新命令
+  在每次调度时，需要将参数 `dt.args.bizdate` 设置为具体的日期值，并执行刷新命令。
+
+  调度刷新命令示例
+
+  ```sql
+  SET dt.args.bizdate=20241130; -- ${bizdate}由Studio每次替换为具体的值
+  REFRESH DYNAMIC TABLE DT PARTITION (pt ='20241130');
+  ```
+
+**案例二：增量任务数据补数，在某些情况下，用户可能需要向已有的分区中补充数据**。
+
+* 方法 1：向源表补充数据，用户可以直接向源表中补充数据。这些补充的数据将通过相应的 REFRESH 任务自动反映到 Dynamic Table（DT）中。
+
+  操作步骤
+
+  1. 直接向源表插入或更新数据。
+  2. 执行 REFRESH 任务，以将更改同步到 DT 中。
+* 方法 2：使用 DML 语句直接向 DT 补充数据，用户也可以使用 DML 语句直接向 DT 的特定分区中插入数据。
+  操作步骤
+  1. 使用 DML 语句向 DT 的特定分区插入数据。
+  2. 请注意，直接修改 DT 将导致下一次该分区的全量刷新。如果用户不希望出现全量刷新的结果，应避免调度该分区的 REFRESH 任务。
+     示例代码
+  ```sql
+  INSERT INTO DYNAMIC TABLE incremental_dt VALUES (...);
+  ```
+
+**案例三：多表join**
+
+```

+
+**注意事项**
+
+* 直接向 DT 插入的数据将参与 DT 的下游计算。如果下游的老分区不需要这些数据，请不要调度涉及这些数据的分区的 REFRESH 任务。
+* 其他未受影响的分区仍然可以进行增量刷新。
+
+**案例三：在不同 VC 中执行增量任务，对于参数化声明的分区化 DT，不同分区的刷新任务可以同时执行。用户可以根据需要将不同的 REFRESH 任务分配到不同的虚拟集群（VC）中执行**。
+操作步骤
+
+1. 根据实效性要求和资源需求，将不同的 REFRESH 任务分配到不同的 VC 中。
+2. 例如，对于实效性要求较高的新分区，可以将其 REFRESH 任务放在资源较多的大 VC 中执行。
+3. 对于其他老分区的补充任务，可以将其 REFRESH 任务放在资源较少的小 VC 中执行。

+# 创建Hive External Catalog
+
+创建 Hive External Catalog 的步骤如下：
+
+1. [创建存储连接](create-storage-connection.md)：首先需要创建一个存储连接，用于访问对象存储服务。
+2. [创建 Catalog Connection](create-catalog-connection.md)：使用存储连接信息和 Hive Metastore 地址创建 Catalog Connection。
+3. 创建External Catalog：使用 Catalog Connection 创建外部 Catalog，以便在数据湖中访问外部数据。
+
+## 语法
+
+```SQL
+CREATE EXTERNAL CATALOG catalog_name
+    CONNECTION catalog_api_connection;
+```
+
+**参数说明**
+
+* **catalog_api_connection**：Catalog Connection 名称。目前只支持 HIVE。[参考创建catalog conneciton](create-catalog-connection.md)

+> Lakehouse 支持通过 Kerberos 认证连接到启用了安全认证的 Hive Metastore 和 HDFS 集群。
+>
+> **Step 0：前置条件**
+>
+> 1. **Kerberos 环境**：确保您的 Hive Metastore 和 HDFS 集群已启用 Kerberos 认证。
+> 2. **认证文件**：准备以下必需的 Kerberos 认证文件：
+>
+>   * `krb5.conf`：Kerberos 配置文件
+>   * `hive.keytab`：服务主体的 keytab 文件
+>
+> 3. **网络连通性**：确保 ClickZetta 可以访问 Kerberos KDC 和 Hive Metastore 服务。
+>
+> **Step 1**：通过 [客户端工具](comprehensive_guide_to_ingesting_dbv_sql_put.md) 将 Kerberos 配置文件和 keytab 文件上传到 Volume 中：
+>
+> ```
+> -- upload krb5.conf
+> PUT '/etc/krb5.conf' TO USER VOLUME FILE 'krb5.conf';
+>
+> -- upload keytab 
+> PUT '/path/to/hive.keytab' TO USER VOLUME FILE 'hive.keytab';
+> ```
+>
+> **Step 2**：使用以下语法创建支持 Kerberos 认证的 catalog connection：
+>
+> ```
+> CREATE CATALOG CONNECTION conn_hms_kerberos_auth
+> TYPE HMS
+> AUTH_TYPE = 'kerberos'
+> KERBEROS_CLIENT_PRINCIPAL = 'hive/localhost@YOUR-REALM.COM'

+## 功能概述
+
+在数据湖架构中，Hive Catalog 是一个关键组件，用于将数据湖与外部的元数据存储（例如 Hive Metastore）关联起来。通过创建 Hive Catalog，用户可以实现元数据的统一管理和访问，从而直接读取存储在外部系统中的数据。Apache Hive 已成为数据仓库生态系统的核心，不仅是大数据分析和 ETL 的 SQL 引擎，还是一个数据管理平台，可用于发现、定义和演化数据。同时，Lakehouse 支持读取和写入 Hive 数据。
+
+## 使用限制
+
+* 使用前请注意，需要保证 Lakehouse 和 Hive 集群网络连通。
+* 目前，云器 Lakehouse 的外部 Catalog 功能支持以下外部数据源：
+  * Hive on OSS（阿里云对象存储服务）
+  * Hive on COS（腾讯云对象存储服务）
+  * Hive on S3（AWS 对象存储服务）
+  * Hive on GCS（Google云对象存储服务）
+  * Hive on HDFS (Preview，请联系 Lakehouse 支持)
+* 同时支持读取和写入。写入格式支持 Parquet、ORC、Text 文件格式。
+
+### 创建外部 Catalog
+
+**创建 Hive Catalog 的步骤**
+
+1. **创建存储连接**：首先需要创建一个存储连接，用于访问对象存储服务。
+2. **创建 Catalog Connection**：使用存储连接信息和 Hive Metastore 地址创建 Catalog Connection。
+3. **创建外部 Catalog**：使用 Catalog Connection 创建外部 Catalog，以便在数据湖中访问外部数据。
+
+#### 创建存储连接
+
+创建存储连接可参考文档 [创建STORAGE CONNECTION](aliyun_storage_connection.md)。
+
+```SQL
+CREATE STORAGE CONNECTION if not exists catalog_storage_oss
+    type OSS
+    ACCESS_ID='LTAIxxxxxxxxxxxx'
+    ACCESS_KEY='T8Gexxxxxxmtxxxxxx'
+    ENDPOINT='oss-cn-hangzhou-internal.aliyuncs.com';
+```
+
+#### 创建 Catalog Connection
+
+```SQL
+CREATE CATALOG CONNECTION if not exists catalog_api_connection
+    type hms
+    hive_metastore_uris='xxx:9083'
+    storage_connection='catalog_storage_oss';
+```
+
+#### 创建外部 Catalog
+
+```SQL
+CREATE EXTERNAL CATALOG test_external_catalog
+    CONNECTION catalog_catalog_connection;
+```
+
+#### 使用 Catalog
+
+```SQL
+--列出catalog下的schema
+show schemas in test_external_catalog;
+--列出catalog下的所有表
+show tables in test_external_catalog.my_external_test;
+--查寻catalog下的表
+select * from test_external_catalog.my_external_test.test;
+--查看catalog下的表结构
+desc test_external_catalog.my_external_test.test;
+```
+
+#### 使用 Hive 表和 Lakehouse 表关联查询
+
+其中，`test_external_catalog.my_external_test.test` 是 Hive 中的表，`public.test` 是 Lakehouse 的内部表。
+
+```
+select * from 
+test_external_catalog.my_external_test.test a
+left join 
+public.test b 
+on a.id=b.id;
+```

+## 创建倒排索引
+
+具体介绍参考[倒排索引](inverted-index.md)介绍
+
+### 语法
+
+```SQL
+CREATE TABLE table_name(
+  columns_difinition,
+  INDEX index_name (column_name) INVERTED [COMMENT '']  PROPERTIES('analyzer'='english｜chinese|keyword｜unicode'),
+  INDEX index_name (column_name) INVERTED [COMMENT '']  PROPERTIES('analyzer'='english｜chinese|keyword｜unicode'),
+....
+  INDEX index_name (column_name) INVERTED [COMMENT '']  PROPERTIES('analyzer'='english｜chinese|keyword｜unicode')
+);
+```
+
+**columns\_difinition**:定义表的字段信息，最后一个字段必须使用逗号隔开
+
+**INDEX**：关键字
+
+**index\_name**：自定义index的名称
+
+**column\_name**：需要添加索引的字段名称
+
+**INVERTED**：关键字，表示倒排索引
+
+**COMMENT**：指定index的说明信息
+
+**PROPERTIES**：指定INDEX的参数，支持的属性目前支持指定分词。数值和日期类型则不需要指定properties，如果是字符串类型要求必须指定分词
+
+* 分词参数：'analyzer'='english｜chinese | keyword｜unicode'，用于指定文本分词的策略，适用于不同的语言和需求。
+  * **keyword**: 此类型的字段不会进行分词。整个字符串被视为单一的词根，并存储在倒排索引中。搜索时，需要提供完整的字段值以实现精确匹配。
+  * **english**: 专为英文设计的分词器，仅识别连续的ASCII字母和数字，并将文本统一转换为小写。适合处理英文内容，忽略非字母数字字符。
+  * **chinese**: 中文文本分词插件，识别中文和英文字符，同时过滤掉标点符号，并将英文字母转换为小写。适用于中英文混合文本的处理。
+  * **unicode**: 基于Unicode文本分割算法的分词器，能够识别多种语言的文本边界，有效将文本分割成单词，并将字母转换为小写。适合多语言环境下的文本处理。
+
+## 参考文档
+
+* [构建索引](build-inverted-index.md)
+* [删除索引](DROP-INDEX.md)
+* [列出所有索引](SHOW-INDEX.md)

+# 创建DELTA和HUDI外部表
+
+## 功能
+
+外部表功能允许Lakehouse查询和分析存储在对象存储等外部存储系统中的数据。用户可以直接操作外部数据，而无需将数据导入Lakehouse内部存储，这提供了数据处理的灵活性和便利性。
+
+**外部表的其他命令**：
+
+* **删除外部表**：通过使用`DROP TABLE`语法，删除外部表。
+* **查看外部表详情**：使用`DESC TABLE`语法，您可以快速查看外部表的结构和详细信息。
+* **修改外部表**：修改外部表，`ALTER TABLE`
+* **查看外部表建表语句**：`SHOW CREATE TABLE`语句
+* **参考案例**: 具体如何操作外部表，可以参考[Delta Lake](delta-lake.md)的外部表使用指南。
+
+## 支持的范围
+
+* 支持阿里云对象存储oss、支持腾讯云对象存储cos、支持Aws对象存储S3
+
+## **语法**
+
+```SQL
+CREATE EXTERNAL TABLE [ IF NOT EXISTS ] table_name
+[(
+  column_definition [, column_definition, ...]
+)]
+[PARTITIONED BY (col_name col_type [, col_name col_type, ...] )]
+USING DELTA|HUDI
+CONNECTION connection_name
+LOCATION 'file_path'
+[COMMENT 'table_comment']
+```
+
+## **参数说明**
+
+**必选参数**:
+
+* `CREATE EXTERNAL TABLE`: 声明创建一个外部表。
+
+* `table_name`: 外部表的名称。
+
+* `column_definition`: 列定义，指定列的名称和数据类型。要求必须和delta、hudi中的类型和名称保持一致。参考Lakehouse支持的[数据类型](data-type.md)。可选，Lakehouse支持自动推断列的名称和数据类型
+
+* `USING DELTA|HUDI`: 指定文件格式目前支持Delta Lake和Hudi格式
+
+* `CONNECTION connection_name`: 连接外部数据源的认证信息，`connection_name`是Lakehouse中定义的连接对象名称。用于认证连接信息，连接对象存储。具体创建文档参考[对象存储连接(STORAGE CONNECTION)](Datalake_StorageConnection.md)
+  * 创建oss connection
+  ```
+  CREATE STORAGE CONNECTION my_conn 
+    TYPE COS
+    ACCESS_KEY = '<access_key>'
+    SECRET_KEY = '<secret_key>'
+    REGION = 'ap-shanghai'
+    APP_ID = '1310000503';
+  ```
+  * 创建cos connection
+  ```
+  CREATE STORAGE CONNECTION my_conn 
+    TYPE COS
+    ACCESS_KEY = '<access_key>'
+    SECRET_KEY = '<secret_key>'
+    REGION = 'ap-shanghai'
+    APP_ID = '1310000503';
+  ```
+  * 创建s3 connection
+  ```
+  CREATE STORAGE CONNECTION aws_bj_conn
+      TYPE S3
+      ACCESS_KEY = 'AKIAQNBSBP6EIJE33***'
+      SECRET_KEY = '7kfheDrmq***************************'
+      ENDPOINT = 's3.cn-north-1.amazonaws.com.cn'
+      REGION = 'cn-north-1';
+  ```
+
+* `LOCATION 'file_path'`: 使用 `LOCATION 'file_path'` 指令可指定待读取的数据文件路径，支持多种云存储格式。对于 Delta Lake 表，外部表将扫描该位置中的事务日志文件（如 `_delta_log/00000000000000000000.json` 或 `_delta_log/00000000000000000010.checkpoint.parquet`），以确定最新的 Parquet 文件。
+  * file\_path 是一个区分大小写的字符串，代表云存储中文件的位置或前缀（即文件夹），用于限定要加载的文件集。腾讯云对象存储 (COS): cos\://bucketname/path、阿里云对象存储 (OSS): oss//bucketname/path、AWS S3 对象存储: s3://bucketname/path
+
+  * file\_path中指定的路径必须仅包含单个 Delta Lake 或 Hudi 表的数据文件和元数据。即，每个存储位置只能对应一个目录。
+
+  * file\_path读取数据时会使用connection中的权限和认证信息。需要授权GetObject、ListObjects、PutObject、DeleteObject权限
+
+  * 每次读取时都会重新解析 Delta Lake 事务日志，确保获取最新的元数据。因此，不会缓存元数据。
+
+**可选参数**:
+
+* `IF NOT EXISTS`: 如果外部表不存在，则创建它；如果已存在，则不执行任何操作。
+* `PARTITIONED BY (col_name col_type [, col_name col_type, ...])`: 指定分区列及其数据类型，用于数据分区。如果DELTA和HUID是分区表则必须指定
+* `COMMENT 'table_comment'`: 为外部表提供描述性注释。
+
+## 用法说明
+
+* 外部表无法访问归档类型的文件，这些数据需要先还原才能检索
+* 外部表不支持TIME TRAVEL.
+* 删除外部表时只会删除外部表的定义，不会删除对象存储中的文件
+
+## **示例**
+
+1.oss上创建delta外部表
+步骤一：需要创建oss connection。具体文档参考[腾讯云存储连接创建](cos_storage_connection.md)
+步骤二：创建外部表，指定外部表的位置

+# 创建Kafka外部表
+
+首先，需要创建一个存储连接，用于连接到 Kafka 服务器，连接前需要保证您的Kafka和Lakehouse网络打通，网络打通方式可以参考[私网连接](private_link.md)。本文介绍创建Kafka存储连接和Kafka外部表。
+
+**外部表的其他命令**：
+
+* **删除外部表**：通过使用`DROP TABLE`语法，删除外部表。
+* **查看外部表详情**：使用`DESC TABLE`语法，您可以快速查看外部表的结构和详细信息。
+* **修改外部表**：修改外部表，`ALTER TABLE`
+* **查看外部表建表语句**：`SHOW CREATE TABLE`语句
+* **参考案例**: 具体如何操作外部表，可以参考[Delta Lake](delta-lake.md)的外部表使用指南。
+
+## 创建Kafka存储连接
+
+### 语法
+
+```SQL
+CREATE STORAGE CONNECTION connection_name
+    TYPE kafka
+    BOOTSTRAP_SERVERS = ['server1:port1', 'server2:port2', ...]
+    SECURITY_PROTOCOL = 'PLAINTEXT';
+```
+
+### 参数说明
+
+* **connection\_name**: 连接的名称，用于后续引用。
+* **TYPE**: 连接类型，此处为 `kafka`。
+* **BOOTSTRAP\_SERVERS**: Kafka 集群的地址列表，格式为 `['host1:port1', 'host2:port2', ...]`。
+* **SECURITY\_PROTOCOL**: 安全协议，目前只支持 `PLAINTEXT`。不支持**SSL**或者**SASL\_SSL**
+
+### 示例
+
+```SQL
+CREATE STORAGE CONNECTION test_kafka_conn
+    TYPE kafka
+    BOOTSTRAP_SERVERS = ['47.99.48.62:9092']
+    SECURITY_PROTOCOL = 'PLAINTEXT';
+```
+
+## 创建Kafka外部表
+
+在创建了存储连接之后，可以定义外部表来读取 Kafka 中的数据。
+
+### 语法
+
+```SQL
+CREATE EXTERNAL TABLE IF NOT EXISTS external_table_name (
+ `topic` string,
+ `partition` int,
+ `offset` bigint,
+ `timestamp` timestamp_ltz,
+ `timestamp_type` string,
+`headers` map<string, string>,
+ `key` binary, `value` binary)
+USING kafka

+# CREATE SCHEMA FROM SHARE
+
+## 功能
+
+`CREATE SCHEMA FROM SHARE` 语句用于使用被分享数据。该语句以 schema 为单位提取指定 share 对象中包含的数据对象，以便在数仓中对这些数据进行查询或处理。
+
+## 语法
+
+```SQL
+CREATE SCHEMA <new_schema_name> FROM SHARE SHARE <instance_name>.<share_name>.<schema_name> ;
+```
+
+## 参数说明
+
+**new_schema_name**: 基于 share 中的数据创建在本地数仓中的 schema 名称；注意该 schema 不可与工作空间中其他 schema 重名，且该 schema 创建后为只读 schema，不可在其中创建其他数据对象。
+
+**instance_name.share_name**: 被提取的 share 名称。因不同服务实例可能共享同名的 share 对象，所以需要在 share 名称前加上 instance 名称以准确标识一个唯一的 share 对象。该信息可以通过具备实例管理员（instance\_admin）或工作空间管理员（workspace\_admin）角色的用户，执行`show shares；` 语句来获取。
+
+![](.topwrite/assets/image_1741002148136.png)
+
+**schema_name**: 指需要被提取的数据。提取数据是以 schema 为单位的，语句执行后 new_schema_name 中所包含的数据对象（table、view 等）与 share 中 schema_name 下所包含的数据对象一致。所以这里需要填入要提取的 share 中的 schema_name。
+
+该信息可以通过具备实例管理员（instance\_admin）或工作空间管理员（workspace\_admin）角色的用户，执行`desc share <instace_name>.<share_name>；` 语句来获取。一个share对象中可能包含多个schema，使用需要提取的schema的名称。

+# CREATE SQL FUNCTION
+
+## 概述
+
+`CREATE FUNCTION` 语句用于在 Lakehouse 中创建 SQL 标量函数或表函数。这些函数可以接受一组参数，并返回标量值或一组行。本文将详细介绍其语法、参数、使用示例。
+
+## 语法
+
+```sql
+CREATE [OR REPLACE] FUNCTION [IF NOT EXISTS]
+    function_name ( [ function_parameter [, ...] ] )
+     [ RETURNS data_type | RETURNS TABLE(column_spec)]
+   AS|RETURN { expression | query };
+
+function_parameter
+    parameter_name data_type ;
+
+column_spec
+    column_name data_type ;
+```
+
+## 参数说明
+
+* `OR REPLACE`
+  * 如果指定此参数，将替换具有相同名称和签名（参数数量和类型）的现有函数。
+  * 不能与 `IF NOT EXISTS` 同时使用。
+* `IF NOT EXISTS`:如果指定，仅在函数不存在时才会创建。
+* `function_name`:函数的名称，可以使用schema名称限定。
+* `function_parameter`
+  * `parameter_name`：参数名称必须在函数中唯一。
+  * `data_type`：支持的任何数据类型。
+* `RETURNS data_type`
+  * 标量函数的返回数据类型。如果未提供数据类型，将从函数体派生。
+* `RETURNS TABLE`：定义返回表结构，需指定列名和数据类型
+* `AS|RETURN {expression | query}`
+  * 函数的主体。对于标量函数，可以是表达式或查询；对于表函数，只能是查询。
+
+
+## 示例
+
+* 创建和使用 SQL 标量函数
+
+```sql
+-- 创建一个函数,指定返回值
+CREATE FUNCTION public.area(x DOUBLE, y DOUBLE) 
+RETURNS DOUBLE
+RETURN x * y;
+-- 在查询中使用函数
+SELECT public.area(3, 4);
+-- 输出：12.0
+
+-- 创建一个函数,使用AS指定处理逻辑
+CREATE FUNCTION public.area2(x DOUBLE, y DOUBLE)
+RETURNS double
+AS x * y;
+SELECT public.area2(3, 4);
+
+```
+
+* 指定返回类型
+
+```
+CREATE  FUNCTION public.hello()
+RETURNS STRING
+AS  'Hello World!';
+SELECT public.hello();
+```
+
+* 在expression使用内置函数
+
+```sql
+CREATE FUNCTION public.roll_dice(num_dice INT  ,
+                          num_sides INT   )
+RETURNS INT
+COMMENT 'Roll a number of n-sided dice'
+RETURN (rand() * num_sides)::INT + 1;
+SELECT public.roll_dice(3, 10);
+```
+
+* 返回一个返回表类型
+
+```
+CREATE TABLE employee (
+    id INT,
+    name STRING,
+    deptno INT
+);
+INSERT INTO employee (id, name, deptno)
+VALUES
+    (1, 'Alice', 10),
+    (2, 'Bob', 10),
+    (3, 'Charlie', 20),
+    (4, 'David', 10),
+    (5, 'Eve', 20);
+CREATE OR REPLACE FUNCTION ga1_1.getemps(deptno INT)
+    RETURNS TABLE (name STRING)
+    RETURN SELECT name FROM employee e WHERE e.deptno = deptno;
+SELECT * FROM ga1_1.getemps(10);
+```
+
+## 注意事项
+
+* 使用函数时必须指定创建时函数所在的Schema否则会错函数找不到。
+  您可以通过设置参数来cz.sql.remote.udf.lookup.policy避免报错。该参数是。动态切换 UDF 与内置函数的解析优先级。默认行为，使用UDF时必须带SCHEMA前缀，如下案例
+  ```
+  --创建函数
+  CREATE FUNCTION public.lower()
+  RETURNS STRING
+  AS 'Hello World!';
+  --使用函数，必须写SCHMA否则会报错函数找不到
+  SELECT public.lower();
+  -- 策略1：优先调用内置函数,可以不用写SCHMA。如果和内置函数同名优先使用内置函数
+  SET cz.sql.remote.udf.lookup.policy = builtin_first;
+  SELECT lower();
+  -- 策略2：优先调用UDF（适配MC/Spark作业场景）。如果和内置函数同名优先使用udf
+  SET cz.sql.remote.udf.lookup.policy = udf_first;
+  SELECT lower();
+  ```

+# 创建STORAGE CONNECTION
+
+Storage Connection 主要用于存储第三方存储服务的身份认证信息，使 Lakehouse 能够安全地访问和管理这些存储服务中的数据。
+
+* 目前支持对象存储、Kafka、HDFS。其中对象存储包括腾讯云COS、阿里云OSS和AWS S3。
+* 目前不支持跨云厂商创建。比如您的 Lakehouse 实例运行在阿里云上，无法访问腾讯云的 COS 数据。
+
+## 创建阿里云存储连接
+
+本步骤的目标是：允许 Lakehouse 实例通过 VOLUME 对象，处理阿里云对象存储 OSS 中的数据。为了完成这个目标，可以通过阿里云提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
+
+### 基于AK密钥方式：
+
+仅需提供带有访问 OSS 权限的账号的 AccessKey ID 和 AccessKey Secret 信息，利用这些信息创建存储连接 (Storage Connection) 对象，示例如下：
+
+```
+CREATE STORAGE CONNECTION if not exists hz_conn_ak
+    TYPE oss
+    ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com'
+    ACCESS_ID = 'LTAI5tMmbq1Ty1xxxxxxxxx'
+    ACCESS_KEY = '0d7Ap1VBuFTzNg7gxxxxxxxxxxxx';
+```
+
+### 基于角色授权方式（RoleARN）
+
+需要创建一个角色和权限策略：权限策略代表OSS 服务的访问策略，将这个策略授权给创建的角色。
+
+**以下主要讲述角色授权方式 (RoleARN) 的具体操作步骤**：
+
+1. 阿里云侧操作：在阿里云 RAM 控制台中创建权限策略 (CzUdfOssAccess)：注意：需要用户具有 RAM 权限
+
+* 访问阿里云访问控制（RAM）产品控制台
+* 左侧导航栏 **权限管理** -> **权限策略**，在权限策略界面选择 **创建权限策略**
+* 在**创建权限策略**页面选择 **脚本编辑** 页签，将下面`  [bucket_name_1|2|3]  `替换为实际的 OSS bucket 名称。注意：按照阿里云OSS 的约定，相同的 bucket 需要有两条 Resource 条目：`"acs:oss:*:*:bucket_name_1" `与 `"acs:oss:*:*:bucket_name_1/*"`同时存在才能达到授权效果：
+
+```JSON
+{
+    "Version": "1",
+    "Statement": [
+        {
+            "Effect": "Allow",
+            "Action": [
+                "oss:GetObject",
+                "oss:ListObjects",
+                "oss:PutObject",
+                "oss:DeleteObject"
+            ],
+            "Resource": [
+                "acs:oss:*:*:bucket_name_1",
+                "acs:oss:*:*:bucket_name_1/*",
+                "acs:oss:*:*:bucket_name_2",
+                "acs:oss:*:*:bucket_name_2/*",
+                "acs:oss:*:*:bucket_name_3",
+                "acs:oss:*:*:bucket_name_3/*"
+            ]
+        }
+    ]
+}
+```
+
+![](.topwrite/assets/OSS_P.jpeg)
+
+^
+
+2. 阿里云侧：在阿里云 RAM 中创建角色CzUDFRole：
+
+* 在阿里云访问控制（RAM）控制台左侧导航栏 **身份管理** -> **角色**，点击 **创建角色**
+
+* 在 **创建角色** 页面中，选择类型为 **阿里云账号**，在 **配置角色** 中填写自定义角色名称（如 CzUDFRole），在 **选择信任的云账号** 中选择 **其他云账号**，并填入账号 ID：1384322691904283，点击 **完成**。
+
+* 创建完成之后，点击**为角色授权**: 在**自定义策略**中，将刚创建的策略（CzUdfOssAccess）授权给该角色。在角色 CzUDFRole 详情页中，获取该角色的 RoleARN 信息：`'acs:ram::1222808864xxxxxxx:role/czudfrole'`
+
+![](.topwrite/assets/20231113-153016.jpeg)
+
+3. Lakehouse 侧：创建 Connection
+
+* 在 Studio 或者 Lakehouse JDBC 客户端中执行以下命令：
+
+```SQL
+CREATE STORAGE CONNECTION hz_oss_conn_rolearn 
+    TYPE oss 
+    REGION = 'cn-hangzhou' 
+    ROLE_ARN = 'acs:ram::1222808864467016:role/czudfrole' 
+    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com';
+```
+
+* 执行 `desc connection` 获取 `external ID `信息：本实例中，external ID 为：`O0lQUogDJajHqnAQ`
+
+> 为了防止 ROLE\_ARN 被第三方获取进行未授权的数据访问，可以使用` EXTENRAL ID` 作为一种额外的验证层，确保只有当请求中包含了预设的 `EXTERNAL ID` 时，这一访问才会被允许。这意味着即使第三方知道了其他一些访问信息（如角色ARN），没有正确的 `EXTERNAL ID` 也无法访问资源。
+
+![](.topwrite/assets/bloygC9Z6Q.jpg)
+
+4. 客户侧：在阿里云 RAM -> 角色->  信任策略中，修改 CzUDFRole 的**信任策略**：`"sts:ExternalId" `部分
+
+^
+
+```Python
+{
+  "Statement": [
+    {
+      "Action": "sts:AssumeRole",
+      "Condition": {
+        "StringEquals": {
+          "sts:ExternalId": "O0lQUogDJajHqnAQ"
+        }
+      },
+      "Effect": "Allow",
+      "Principal": {
+        "RAM": [
+          "acs:ram::1384322691904283:root"
+        ]
+      }
+    }
+  ],
+  "Version": "1"
+}
+```
+
+##
+
+## 创建腾讯云存储连接
+
+本步骤的目标是：允许 Lakehouse 集群访问腾讯云上的对象存储 COS。为了完成这个目标，可以通过腾讯云**访问管理**提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
+
+### 基于AK密钥方式
+
+```sql
+CREATE STORAGE CONNECTION my_conn 
+  TYPE COS
+  ACCESS_KEY = '<access_key>'
+  SECRET_KEY = '<secret_key>'
+  REGION = 'ap-shanghai'
+  APP_ID = '1310000503';
+```
+
+**参数**：
+
+* **TYPE**：为对象存储类型，腾讯云应填写 `COS`（大小写不限）
+
+* **ACCESS\_KEY / SECRET\_KEY**：为腾讯云的访问密钥，获取方式参考：[访问密钥](https://cloud.tencent.com/document/product/598/40488)
+
+* **REGION**：指腾讯云对象存储 COS 的数据中心所在的地域。相同地域内云器 Lakehouse 访问腾讯云 COS 时，COS服务将自动路由至内网访问。具体取值请参考腾讯云文档：[地域和访问域名](https://cloud.tencent.com/document/product/436/6224)。
+
+* **APP\_ID**：腾讯云存储桶的命名由存储桶名称（BucketName）和 APPID 两部分组成，两者以中划线“-”相连。例如 `examplebucket-1310000503`，其中 `examplebucket` 为用户自定义，`1310000503` 为系统生成数字串（APPID）。
+
+### 基于角色授权
+
+STEP1: 创建权限策略 (LakehouseAccess)：
+
+* 登录腾讯云，进入**访问管理**产品控制台
+* 在**访问管理**页面左侧导航栏进入**策略**，在权限控制界面选择 **新建自定义策略** -> **按策略生成器创建** -> **可视化策略生成器**。
+* 在**可视化策略生成器**页签中：**服务**（**Service**）: 选择 **对象存储(cos**)；**操作（Action）**：选择 **全部操作**（可根据实际需要的操作，做更细粒度的选择）；**资源（Resource**）：根据需要选择**全部资源**或者**特定资源**。本示例中选择特定资源，为上海区的` cz-volume-sh-1311343935`![](.topwrite/assets/20240625-211734.jpeg)
+* 点击**下一步**，填写**策略名称**为 LakehouseAccess 和描述后，点击**完成**
+
+STEP2：客户侧创建角色（LakehouseRole）
+
+* 进入腾讯云**访问管理**产品控制台
+* 在**访问管理**页面左侧导航栏进入**角色** -> **新建角色** -> **腾讯云账户**， 选择**其他主账号**，在 **账号ID** 中输入 `100029595716`（云器的腾讯云主账号），其它选项保持默认，点击**下一步**
+* 在**配置角色策略**配置中，将刚才新建的 LakehouseAccess 自定义策略授权给当前角色。点击 **下一步**，在**角色命名**中填写 `LakehouseRole `完成创建。
+* 创建成功后，在角色列表中，进入角色 `LakehouseRole` 的详情页，获取该角色的 RoleARN 信息：  `qcs::cam::uin/1000*******:roleName/LakehouseRole`
+
+STEP3：Lakehouse 侧创建 Connection
+
+* 在 Studio 或者 Lakehouse JDBC 客户端中执行以下命令：
+
+```
+CREATE STORAGE CONNECTION my_tx_connection_arn
+   TYPE cos
+   REGION = 'ap-shanghai'
+   ROLE_ARN = 'qcs::cam::uin/1000********:roleName/LakehouseRole'
+   APP_ID = '131****35';
+```
+
+* 注意：为了防止 ROLE\_ARN 被第三方获取进行未授权的数据访问，可以使用` EXTENRAL ID` 作为一种额外的验证层，确保只有当请求中包含了预设的 `EXTERNAL ID` 时，这一访问才会被允许。这意味着即使第三方知道了其他一些访问信息（如角色ARN），没有正确的 `EXTERNAL ID` 也无法访问资源。
+* 在创建存储连接的过程中，Lakehouse 会生成此EXTERNAL ID，可以将此EXTERNAL ID 配置到 COS 账号的角色校验中实现访问控制：
+
+```
+-- 查看 EXTERNAL ID 
+DESC CONNECITON my_tx_connection_arn ;
+```
+
+![](.topwrite/assets/20240625-214538.jpeg)
+
+* 客户侧：进入腾讯云**访问管理**控制台中，**角色** -> **LakehouseRole** -> **角色载体**-> **管理载体**，选择 **添加账户** -> 选择**当前主账号**，并填写主账号ID：`100029595716`（云器的腾讯云主账号），并勾选**开启校验**，输入刚才 DESC 结果中的 EXTERNAL\_ID，点击 **确定**-> **更新**
+
+## 创建亚马逊云存储连接
+
+本步骤的目标是：允许 Lakehouse 集群访问亚马逊云 (AWS) 的对象存储 S3。为了完成这个目标，可以通过 AWS 的 **身份与访问管理 (IAM)** 产品提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
+
+### 基于访问密钥
+
+```
+CREATE STORAGE CONNECTION aws_bj_conn
+    TYPE S3
+    ACCESS_KEY = 'AKIAQNBSBP6EIJE33***'
+    SECRET_KEY = '7kfheDrmq***************************'
+    ENDPOINT = 's3.cn-north-1.amazonaws.com.cn'
+    REGION = 'cn-north-1';
+```
+
+**参数**：
+
+* TYPE：为对象存储类型，AWS 应填写 S3（大小写不限）
+* ACCESS\_KEY / SECRET\_KEY：为AWS 的访问密钥，获取方式参考：[访问密钥](https://docs.aws.amazon.com/zh_cn/IAM/latest/UserGuide/id_credentials_access-keys.html)
+* ENDPOINT:  S3 的服务地址，AWS 中国区分为北京区和宁夏区，北京区的S3 的服务地址为 `s3.cn-north-1.amazonaws.com.cn`， 宁夏区 `s3.cn-northwest-1.amazonaws.com.cn`，可参考：[中国区终端节点](https://docs.amazonaws.cn/aws/latest/userguide/endpoints-arns.html) 分别找到北京区域和宁夏区域的终端节点 -> Amazon S3 对应的终端节点
+* REGION：AWS 中国区分为北京区和宁夏区，区域值为：北京区 `cn-north-1`， 宁夏区 `cn-northwest-1`，可参考：[中国区终端节点](https://docs.amazonaws.cn/aws/latest/userguide/endpoints-arns.html)
+
+### 基于角色授权
+
+需要在目标云对象存储 S3 所属的账号，在 IAM 中创建一个**权限策略**和**角色**：权限策略代表访问AWS S3 数据的规则，将这个策略授权给创建的角色。云器 Lakehouse 通过扮演这个角色来实现与 S3 中数据的读写操作。
+
+STEP1: AWS侧创建权限策略 (LakehouseAccess )：
+
+* 登录AWS 云平台，进入**身份与访问管理(IAM**) 产品控制台
+* 在 IAM 页面左侧导航栏进入 **账户设置**，在 **Security Token Service (STS)** 区域的 **终端节点** 列表中，找到当前实例对应云器Lakehouse 的区域，如果 **STS 状态** 为“未开启”，请将其开启。
+* 在 IAM 页面左侧导航栏进入 **策略**，在 **策略** 界面选择 **创建策略**，在策略编辑器中选择 JSON 方式
+* 将要添加允许云器Lakehouse 访问 S3 bucket 和目录的策略。下面是策略的样例，请用实际的bucket 和路径前缀名称替换 `<bucket>` 和 `<perfix>` 名称
+* **注意**：请将 `"s3:prefix" `项中填写:  `["*"]` or `["<path>/*"]` 分别代表授予对指定 bucket 或 bucket 中路径中的所有前缀的访问权限。
+

+                }
+            }
+        }
+    ]
+}
+```
+
+* 点击 **下一步**，输入策略名称（如 LakehouseAccess）和描述（选填）
+* 点击创建策略完成策略创建
+
+STEP2: AWS侧创建角色 (LakehouseVolumeRole)：
+
+* 登录AWS 云平台，进入**身份与访问管理(IAM**) 产品控制台
+* 在 IAM 页面左侧导航栏进入**角色** -> **创建角色** -> **AWS账户**，选择 **另一个AWS账户**，在 Account ID 输入 `028022243208`
+
+> 注意：为了防止 ROLE\_ARN 被第三方获取进行未授权的数据访问，可以勾选 **选项** 中的 **需要外部 ID（第三方担任此角色时的最佳实践）**，勾选之后 **EXTENRAL ID** 项可以填写 `000000` 占位符稍后填充。`EXTERNAL ID` 作为一种额外的验证层，确保只有当请求中包含了预设的 `EXTERNAL ID` 时，这一访问才会被允许。这意味着即使第三方知道了其他一些访问信息（如角色ARN），没有正确的 `EXTERNAL ID` 也无法访问资源。
+
+![](.topwrite/assets/image_1728551322654.png)
+
+* 选择下一步，在添加权限（Add permissions）页面，选择STEP1 中创建的策略 `LakehouseAccess `**后**，选择下一步
+* 填写 Role name (例：`LakehouseVolumeRole` ) 和描述，点击 **创建角色** 完成角色创建
+* 在角色详情页中，获取 **Role ARN** 的值，用来创建 STORAGE CONNECTION
+
+![](.topwrite/assets/image_1728551348143.png)
+
+STEP3: 云器 Lakehouse 侧创建 STORAGE CONNECTION ：
+
+* 在 Studio 或者 Lakehouse JDBC 客户端中执行以下命令：
+
+```
+CREATE STORAGE CONNECTION aws_bj_conn_arn
+  TYPE S3
+  REGION = 'cn-north-1'
+  ROLE_ARN = 'arn:aws-cn:iam::02802*******:role/LakehouseVolumeRole';
+```
+
+* 在创建存储连接的过程中，Lakehouse 会生成此EXTERNAL ID，可以将此EXTERNAL ID 配置到 STEP2创建的 AWS IAM 角色（`LakehouseVolumeRole`）的 Trust Policy 中，实现附加的访问控制：
+
+```
+-- 查看 EXTERNAL ID 
+DESC CONNECITON aws_bj_conn_arn ;
+```
+
+![](.topwrite/assets/20240626-215920.jpeg)
+
+* 在AWS IAM 的控制台，左侧导航栏中进入角色 **Roles**，找到 STEP2 中创建的角色并进入角色详情页面，在 **Trust relationships** 中将 `sts:ExternalId `的值`  000000  `替换为 DESC 结果中的` EXTERNAL_ID`。点击**更新** 完成角色策略更新。
+
+## 创建Kafka存储连接
+
+Kafka连接主要是用于Kafka外部表，可以方便地从 Kafka 中读取数据流，并将这些数据流作为表进行查询和分析。
+
+### 语法
+
+```SQL
+CREATE STORAGE CONNECTION connection_name
+    TYPE kafka
+    BOOTSTRAP_SERVERS = ['server1:port1', 'server2:port2', ...]
+    SECURITY_PROTOCOL = 'PLAINTEXT';
+```
+
+### 参数说明
+
+* **connection\_name**: 连接的名称，用于后续引用。
+* **TYPE**: 连接类型，此处为 `kafka`。
+* **BOOTSTRAP\_SERVERS**: Kafka 集群的地址列表，格式为 `['host1:port1', 'host2:port2', ...]`。
+* **SECURITY\_PROTOCOL**: 安全协议，可以是 `PLAINTEXT` 等。
+
+### 示例
+
+```SQL
+CREATE STORAGE CONNECTION test_kafka_conn
+    TYPE kafka
+    BOOTSTRAP_SERVERS = ['47.99.48.62:9092']
+    SECURITY_PROTOCOL = 'PLAINTEXT';
+```
+
+## 创建 HDFS 连接
+
+HDFS 连接主要用于 Lakehouse 联邦查询，可以方便地读取 HDFS 中的数据。
+
+### 语法
+
+```SQL
+CREATE STORAGE CONNECTION <connection_name> TYPE HDFSNAME_NODE='<nameservice_id>'NAME_NODE_RPC_ADDRESSES=['<rpc_address>']
+```
+
+### 参数说明
+
+* `<connection_name>` ：自定义的连接名称，用于标识该 HDFS 连接，例如`hdfs_conn`。
+* `TYPE HDFS` ：指定连接类型为 HDFS。
+* `NAME_NODE` ：对应 [HDFS 配置](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HDFSHighAvailabilityWithNFS.html)中的`dfs.nameservices`，是 HDFS 集群的逻辑名称，例如`zetta-cluster`。
+* `NAME_NODE_RPC_ADDRESSES` ：对应 [HDFS 配置](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HDFSHighAvailabilityWithNFS.html)中的`dfs.namenode.rpc-address`，是 NameNode 的 RPC 地址，格式为`[<host>:<port>]`，例如`['11.110.239.148:8020']`。
+
+### 案例
+
+```SQL
+CREATE STORAGE CONNECTION hdfs_connTYPE HDFSNAME_NODE='zetta-cluster'NAME_NODE_RPC_ADDRESSES=['11.110.239.148:8020'];

+## 功能
+
+创建同义词，同义词synonym是一个数据库对象，类似给对象起一个别名。支持为以下对象创建同义词：table、table stream、dynamic table、materialzied view、volume、function。
+
+## 创建语法
+
+```SQL
+CREATE  [TABLE|VOLUME|FUNCTION] SYNONYM [schema_name.] synonym_name FOR object COMMENT''
+object ::=
+workspace_name.schema_name.object_name|schema_name.object_name|object_name
+```
+
+* TABLE|VOLUME|FUNCTION：表示给哪种对象命名同义词，
+
+  * **TABLE**：这是默认选项。用于为table、table stream、materialzied view、dynamic table命名同义词。在这些情况下，“table”关键字是可选的。
+  * **VOLUME**：volume命名同义词时，必须明确指定此关键字。如果省略，系统将默认寻找同名的表格对象。
+  * **FUNCTION**：function命名同义词时，此关键字是必填项。如果未指定，系统同样会默认寻找同名的table对象
+
+* synonym\_name:同义词名称，遵循元数据规范
+
+* object：指定基对象的名称，支持workspace\_name.schema\_name\_2.object\_name、schema\_name\_2.name格式如果省略schema则使用当前schema中的对象
+
+### 权限
+
+* 创建create synonym需要create synonym权限
+
+```SQL
+grant create synonym  on schema  scname to user uat_test_01;
+```
+
+### 使用方式
+
+1. 具体使用方式参考[同义词使用](synonym.md)
+2. 当删除同义词引用（例如 TABLE、TABLE STREAM、MATERIALIZED VIEW、DYNAMIC TABLE、VOLUME、FUNCTION 等）后，如果随后创建了与之前同名的新引用，则系统将自动指向并使用新的引用。这意味着任何对原对象的引用，在新对象创建后，都将自动适用于新对象，而无需更改现有的查询或代码。
+
+## 使用案例
+
+案例一：给表创建同义词
+
+```SQL
+CREATE TABLE employees(id int,name string,skills array<string>);
+INSERT INTO employees (id, name, skills) VALUES
+(1, 'John Doe', ['Java', 'Python', 'SQL']),
+(2, 'Jane Smith', ['C++', 'Hadoop', 'SQL']),
+(3, 'Bob Johnson', ['Python', 'Docker']);
+CREATE TABLE SYNONYM employees_syno FOR employees;
+--查询同义词
+SELECT * FROM employees_syno;
++----+-------------+-------------------------+
+| id |    name     |         skills          |
++----+-------------+-------------------------+

+| 2  | Jane Smith  | ["C++","Hadoop","SQL"]  |
+| 3  | Bob Johnson | ["Python","Docker"]     |
++----+-------------+-------------------------+
+
+```
+
+案例二：给table stream创建同义词，table stream和table创建同义词语法相同
+
+```SQL
+CREATE  SYNONYM employees_stream_synonym FOR public.employees_stream;
+--删除同义词
+DROP SYNONYM employees_stream_synonym;
+```
+
+案例三：给DYNAMIC TABLE创建同义词，DYNAMIC TABLE和TABLE创建同义词语法相同

+# CREATE TABLE
+
+## 功能
+
+本语句用于创建一个新的表。在Lakehouse中，表是存储数据的基本单位。通过创建表，您可以将数据按照指定的结构进行组织和管理。
+
+## 语法
+
+### 基本建表语句
+
+```SQL
+CREATE TABLE [ IF NOT EXISTS ] table_name
+(
+    column_definition  [column_definition ,...]
+    index_definition_list
+)
+[ PARTITIONED BY (column_name column_type | column_name | transform_function) ]
+[ CLUSTERED BY (column_name,...) 
+    [SORTED BY (column_name [ ASC | DESC ])] 
+    [INTO num_buckets BUCKETS] 
+]
+[ COMMENT 'table_comment' ]
+[PROPERTIES('data_lifecycle'='day_num')];
+
+
+```
+
+### column\_definition说明
+
+#### 基本语法
+
+```
+column_name column_type 
+{ NOT NULL |
+  PRIMARY KEY|
+  IDENTITY[(seed)]|
+  GENERATED ALWAYS AS ( expr ) |
+  DEFAULT default_expression |
+  COMMENT column_comment |   
+}
+```
+
+#### 列类型column\_type
+
+* **column\_type**列类型，支持以下类型：
+
+```SQL
+TINYINT：1字节整数，范围 -128 到 127。
+SMALLINT：2字节整数，范围 -32,768 到 32,767。
+INT：4字节整数，范围 -2,147,483,648 到 2,147,483,647。
+BIGINT：8字节整数，范围 -9,223,372,036,854,775,808 到 9,223,372,036,854,775,807。
+FLOAT：4字节浮点数。
+DOUBLE：8字节浮点数。
+DECIMAL：可变长度的精确数值类型，支持指定精度和小数位数。
+VARCHAR：变长字符串，最大长度限制为 65,533 字符。
+CHAR：定长字符串，长度范围从 1 到 255 字符。
+DATE：日期，格式为 YYYY-MM-DD。
+TIMESTAMP：日期时间，时间戳表示为本地时间,格式为 YYYY-MM-DD HH:MM:SS。
+TIMESTAMP_NTZ：不包含时区信息的日期和时间值，格式为 YYYY-MM-DD HH:MM:SS。
+BINARY：固定长度的二进制字符串。
+BOOLEAN：布尔值，真或假。
+ARRAY：元素类型相同的有序集合。如：ARRAY<INT>
+MAP：键值对集合，键的类型必须相同，值的类型可以相同也可以不同。如：MAP<STRING,INT>
+STRUCT：字段类型不同的记录类型。如：struct<company_name:string,employee_count:int>
+JSON：一种轻量级的数据交换格式。
+VECTOR：数值向量类型，用于存储一系列数值。
+```
+
+* **NOT NULL**：表示该列不允许为NULL,只支持建表时指定不支持使用ALTER语法添加,需要取消NOT NULL约束时。请使用修改表类型语法：
+
+```
+ALTER TABLE table_name CHANGE COLUMN colum_name data_type
+```
+
+比如去除int类型not null约束
+
+```
+CREATE TABLE aa_not_null (id int NOT NULL)
+ALTER TABLE aa_not_null CHANGE COLUMN id TYPE int;
+```
+
+#### 主键（PRIMARY KEY）
+
+* **主键（PRIMARY KEY**） 用于确保表中每条记录的唯一性。在大数据场景下，由于数据量通常非常庞大，为了保证数据的唯一性而对所有 key 进行逐一检查是不现实且低效的，因此一般不推荐在大数据环境中使用主键约束。然而，Lakehouse 仍提供了对主键的支持，以便在特定场景下满足数据完整性的需求。在Lakehouse架构中，定义了主键的表在进行实时数据写入时，系统将自动根据主键值进行数据去重，这对于变更数据捕获（CDC）场景尤为重要。例如，您可以实时地将MySQL数据库的binlog日志同步到Lakehouse，确保数据的一致性。设置完主键需要通过[实时数据接口](java_reference/realtime-upload.md)来处理数据。在CDC实时写入过程中，系统将依据主键自动进行数据去重，以维护数据的准确性和完整性。只支持建表时指定。具体参考文档参考[主键介绍](primary-key.md)
+
+```
+CREATE    TABLE pk_table 
+(id int, col string PRIMARY KEY (id));
+
+CREATE    TABLE pk_table 
+(id int PRIMARY KEY, col string);
+--分桶表定义主键
+CREATE    TABLE pk_table (
+          id int,
+          col string,
+          cluster_key string,
+          PRIMARY key (id)
+          ) CLUSTERED BY (id, cluster_key) SORTED BY (id) INTO 16 BUCKETS;
+
+--分区表定义主键
+CREATE    TABLE pk_table (
+          id int,
+          col string,
+          pt string,
+          PRIMARY key (id, pt)
+          ) PARTITIONED BY (pt);
+```
+
+#### 自增列（IDENTITY\[(seed)]）
+
+* **IDENTITY\[(seed**)]:支持指定自增。无法保证序列中的值是连续的（无间隙），也无法保证序列值按特定顺序分配。因为表中可能会发生其他并发插入。这些限制是设计的一部分，目的是提高性能。具体使用参考[IDENTITY Column文档](IDENTITY-Column.md)
+
+```
+CREATE    TABLE identity_test (id bigint IDENTITY(1), col string);
+```
+
+#### 生成列（GENERATED ALWAYS AS）
+
+* **GENERATED ALWAYS AS (expr**)：通过表达式`expr`自动生成列的值。表达式可以包含常量和内置标量确定性SQL函数，不支持非确定性函数如（current\_date\random\current\_timestamp\上下文函数）或运算符，不支持聚合函数、窗口函数或表函数。支持分区列使用生成列
+
+```
+CREATE TABLE t_genet (col1 TIMESTAMP,pt STRING GENERATED ALWAYS AS (date_format(col1, 'yyyy-MM-dd'))) PARTITIONED BY (pt);
+```
+
+#### 默认值（DEFAULT）
+
+* **DEFAULT default\_expression**：为新添加的列定义一个默认值。如果在INSERT、UPDATE或MERGE操作中未指定该列的值，将自动使用此默认值。对于添加列之前已存在的数据行，该列将填充为null。支持非确定性函数如（current\_date\random\current\_timestamp\上下文函数）和常量值
+
+```
+CREATE TABLE t_default(id INT,col1 STRING DEFAULT current_timestamp());
+```
+
+### 索引定义（index\_definition\_list）
+
+#### 基本语法
+
+```
+INDEX index_name (col_name) index_type [COMMENT 'xxxxxx'] [PROPERTIES('key'='value')]
+```
+
+**columns\_difinition**:定义表的字段信息，最后一个字段必须使用逗号隔开
+
+**INDEX**：关键字
+
+**index\_name**：自定义index的名称
+
+**column\_name**：需要添加索引的字段名称
+
+**index\_type**：索引类型，目前支持[bloomfilter](BLOOMFILTER-INDEX.md)、[inverted](inverted-index.md)、[vector](vector-index.md)
+
+**COMMENT**：指定index的说明信息
+
+**PROPERTIES**：指定INDEX的参数,不同的索引支持不同的参数具体参考对应索引文档
+
+### 分区（PARTITIONED BY）
+
+分区是一种通过在写入时将相似的行分组在一起来加快查询速度的方法。使用分区可以达到数据裁剪，优化查询。查询表时通过WHERE子句查询指定所需查询的分区，避免全表扫描，提高处理效率，降低计算资源。具体可以参考[参考分区介绍](partition_table.md)。 注意执行写入分区时单个任务目前限制2048个分区，超出此限制将会报错：`The count of dynamic partitions exceeds the maximum number 2048`。插入之前建议您先统计分区的数量如：`select count(distinct pt) from table`。如果您确实有这么多分区可以分批次导入或者您可以通过添加参数set cz.sql.table.sink.max.partition.per.thread=10000来修改此限制，lakehouse的分区总数没有限制，会在单个任务限制。如果您的数据量较小建议可以不用设置cluster key和partiiton key。建议单分区和cluster key在百MB到GB级别。例如parquet格式文件压缩后128MB
+
+支持两种写法
+第一种分区字段和类型在create table时声明，在PARTITIONED BY字据中声明字段即可
+
+```SQL
+CREATE TABLE prod.db.sample (
+id bigint,
+category string,
+data string
+)
+PARTITIONED BY(category)
+```
+
+第二种分区字段和类型写在PARTITIONED BY语句中。
+
+```SQL
+CREATE TABLE prod.db.sample (
+id bigint,
+data string)
+PARTITIONED BY(category string)
+```
+
+### 分桶表（CLUSTERED BY）
+
+* CLUSTERED BY：指定Hash Key。Lakehouse将对指定列进行Hash运算，将数据根据Hash值分散到各个数据分桶中。为了避免数据倾斜和热点，并提高并行执行效果，建议选择取值范围大、重复键值少的列作为Hash Key。通常在进行join操作时会有明显效果。建议在数据量大的场景下使用CLUSTERED BY，一般按照一个桶的大小在128MB到1GB之间。如果没有指定分桶，默认为256个buckets。建议SORTED BY和CLUSTERED BY保持一致，以获得更好的性能。当指定SORTED BY子句后，行数据将按照指定的列进行排序。  更多信息可以参考[分桶](cluster-table.md)
+
+```
+--指定分桶并指定排序
+CREATE TABLE sales_data (
+    sale_id INT,
+    product_id INT,
+    quantity_sold INT,
+    sale_date DATE
+) CLUSTERED BY (product_id)
+SORTED BY (sale_date DESC)
+INTO 50 BUCKETS;
+--指定分桶并指定桶的个数
+CREATE TABLE sales_data (
+    sale_id INT,
+    product_id INT,
+    quantity_sold INT,
+    sale_date DATE
+) CLUSTERED BY (product_id)
+INTO 50 BUCKETS;
+```
+
+### SORTED BY
+
+SORTED BY：指定文件内字段的排序方式。Lakehouse的SORTED BY可以单独使用，单独使用时表示在文件内排序。指定SORTED BY可以加速数据检索速度，但是写入时由于要排序，写入时可能会增加耗时
+
+```
+CREATE TABLE sales_data (
+    sale_id INT,
+    product_id INT,
+    quantity_sold INT,
+    sale_date DATE
+) 
+SORTED BY (sale_date DESC);
+```
+
+### PROPERTIES
+
+* 支持设置生命周期'data\_lifecycle'='day\_num'[参考生命周期介绍](data-lifecycle.md)
+* 开启[TABLE STREAM](tablestream_summary.md) ，建表时指定'change\_tracking' = 'true'并不会生效，请使用alter开启
+  ALTER table test\_table set PROPERTIES ('change\_tracking' = 'true');
+* 设置表的缓存策略。partiton.cache.policy.latest.count=num设置表的缓存策略。计算集群可以通过配置 `preload_table`，定时或被触发拉取 `preload_table` 中指定的表数据到计算集群本地的 SSD 硬盘上进行缓存。您还可以在表上设置缓存策略。
+  例如，`partition.cache.policy.latest.count=10` 表示缓存最近的 10 个分区，当新分区添加时，旧分区的缓存将失效。也可以通过alter命令添加该参数
+  例如ALTER table test\_table set PROPERTIES ('partition.cache.policy.latest.count' =10);
+* 设置表的保留周期'data\_retention\_days'='num'，配置Time Travel的数据保留周期，以决定数据在时间旅行窗口中保留的时间长度。
+
+```
+--设置数据生命周期和表删除数据的保留周期
+CREATE TABLE historical_prices (
+    ticker_symbol STRING,
+    trading_date DATE,
+    closing_price DECIMAL(10, 2)
+) PROPERTIES (
+    'data_lifecycle' = '365',
+    'data_retention_days' = '7'
+);
+--修改已有表的生命周期
+ALTER TABLE historical_prices SET PROPERTIES(    'data_lifecycle' = '1')
+```
+
+### 使用LIKE语句建表
+
+```SQL
+CREATE TABLE [ IF NOT EXISTS ] table_name
+LIKE source_table
+[ COMMENT 'table_comment' ];
+```
+
+使用LIKE语句创建新表时，目标表将具有与源表相同的表结构，但不会复制数据。
+
+### 使用AS语句建表
+
+CREATE TABLE AS SELECT（简称CTAS）语句可用于同步或异步查询原表，并基于查询结果创建新表，然后将查询结果插入到新表中。需要注意的是，通过这种方式创建的表不会复制分区信息。
+
+```SQL
+CREATE TABLE [ IF NOT EXISTS ] table_name
+[ AS select_statement ];
+```
+
+## 示例
+
+1.创建分区表
+
+语法一：
+
+```SQL
+CREATE TABLE table_part (id INT, name STRING)
+PARTITIONED BY (age INT);
+```
+
+语法二：
+
+```SQL
+CREATE TABLE table_fpart (id INT, name STRING, dt STRING)
+PARTITIONED BY (dt) COMMENT '11';
+```
+
+2.创建一个自增列作为唯一标识符的商品表
+
+```sql
+CREATE TABLE IF NOT EXISTS products (
+    product_id BIGINT IDENTITY(1) COMMENT '商品ID',
+    name VARCHAR(255) NOT NULL COMMENT '商品名称',
+    price DECIMAL(10, 2) NOT NULL COMMENT '价格'
+) COMMENT '商品列表';
+```
+
+3.创建一个带有生成列的时间戳转换表
+
+```sql
+CREATE TABLE IF NOT EXISTS timestamps (
+    event_time TIMESTAMP COMMENT '事件发生时间',
+    formatted_date STRING GENERATED ALWAYS AS (date_format(event_time, 'yyyy-MM-dd')) COMMENT '格式化后的日期'
+) PARTITIONED BY (formatted_date);
+```
+
+4.创建一个默认值为当前时间戳的活动记录表
+
+```sql
+CREATE TABLE IF NOT EXISTS activities (
+    activity_id BIGINT NOT NULL COMMENT '活动ID',
+    description VARCHAR(255) COMMENT '描述',
+    event_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP COMMENT '记录时间'
+) COMMENT '活动记录';
+```
+
+5.创建一个带有Bloom Filter索引的搜索优化表
+
+```sql
+CREATE TABLE IF NOT EXISTS search_optimized (
+    id BIGINT COMMENT 'ID',
+    description VARCHAR(255) COMMENT '关键词',
+    INDEX bloom_index (id) BLOOMFILTER COMMENT '布隆过滤器索引'
+) COMMENT '用于快速查找的表';
+```
+
+6.创建一个带有倒排索引的文本分析表
+
+```sql
+CREATE TABLE IF NOT EXISTS text_analysis (
+    doc_id BIGINT COMMENT '文档ID',
+    content TEXT COMMENT '内容',
+    INDEX inverted_content (content) INVERTED PROPERTIES ('analyzer' = 'chinese') COMMENT '倒排索引'
+) COMMENT '用于文本分析的表';

+CREATE TABLE IF NOT EXISTS customer_feedback (
+    feedback_id BIGINT COMMENT '反馈ID',
+    feedback JSON COMMENT '反馈内容'
+) COMMENT '客户反馈表';
+```
+
+# 使用说明
+
+### 分区和分桶
+
+* **分区策略的选择**：根据查询模式选择合适的分区字段。通常来说，应该选择那些能够有效缩小扫描范围的列作为分区键。比如时间戳列非常适合用作日期范围查询的分区键。
+
+* **分桶数量的设定**：分桶数目应当根据预计的数据量及硬件资源配置来调整。一般来说，每个bucket大小应在 256MB 到 1GB 之间。过多或过少的分桶都会影响到系统的整体性能。为了获得最佳效果，建议测试不同配置下的表现，并据此做出适当调整。
+
+* **排序字段的选择**：当使用 `SORTED BY` 子句时，选择那些频繁出现在过滤条件中的列作为排序依据。良好的排序可以帮助加速点查询和范围查询的速度，但同时也增加了写入成本。因此，在权衡利弊后作出决策非常重要。
+
+### 索引
+
+用户可以在建表的同时创建多个列的索引。索引也可以在建表之后再添加。如果在之后的使用过程中添加索引，如果表中已有数据，则需要重写所有数据，因此索引的创建时间取决于当前数据量。
+
+### 表属性设置的最佳实践
+
+* **启用数据生命周期管理**：通过设置 `data_lifecycle` 属性，可以让系统自动清理不再需要的历史数据。这对于节省存储非常有用，尤其是在处理日志或交易记录等具有明确保留期限的数据集时
+* **配置变更跟踪**：如果你的应用场景涉及需要获取表的数据变化，则需要开启 `change_tracking` 。常见场景如[TABLE STRAM](tablestream_summary.md)
+* **删除数据设置数据保留周期**:此参数定义了在被删除数据被保留的时间长度，对于需要进行历史数据查询的场景非常重要。例如，[table stream](tablestream_summary.md)、[restore](restore.md) 和[dynamic table](dynamic-table-introduce.md) 等功能都会依赖于这个保留周期设置。Lakehouse默认保留数据一天。根据您的业务需求，您可以通过调整 `data_retention_days` 参数来延长或缩短数据的保留周期。请注意，调整数据保留周期可能会影响存储成本。延长保留周期会增加存储需求，从而可能增加相关的费用。

+# Table Stream 功能
+
+Table Stream是一种实时数据流，用于记录对表所做的数据操作语言（DML）更改，包括插入、更新和删除操作。同时，Table Stream还提供有关每次更改的元数据，以便您可以根据更改的数据采取相应操作。支持在Table、Dynamic Table、Materialized View、External Table(Kafka)创建Table Stream，同时也支持在 External Volume 上创建 Volume Stream，用于监听外部对象存储（如 OSS）中的文件变更事件。
+
+## Table Stream 语法
+
+**Table、Dynamic Table、Materialized View 创建 Table Stream 语法**
+
+```SQL
+CREATE [OR REPLACE] TABLE STREAM [IF NOT EXISTS]
+  <name>
+  ON TABLE <table_name>
+  [TIMESTAMP AS OF timestamp_expression]
+  [COMMENT = '<string_literal>']
+  WITH PROPERTIES ('TABLE_STREAM_MODE' = 'APPEND_ONLY|STANDARD','SHOW_INITIAL_ROWS'='TRUE|FALSE');
+```
+
+* `<name>`：Table Stream的名称。
+
+* `<table_name>`：要获取增量的基表。不支持view。
+
+* `TIMESTAMP AS OF timestamp_expression`：（可选）指定Table Stream应从底层表开始接收更新的时间戳表达式。如果省略此参数，Table Stream将从当前时间开始接收更新。
+
+  * `timestamp_expression`返回结果是一个标准的时间戳类型的表达式，TIMESTAMP AS OF指定的最早时间戳取决[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。如果未指定则使用当前时间戳的版本数据，例如：
+    * `'2023-11-07 14:49:18'`，即可以强制转换为时间戳的字符串。
+    * `cast('2023-11-07 14:49:18 Asia/Shanghai' as timestamp)`。
+    * `current_timestamp() - interval '12' hours`。
+    * 本身就是时间戳或可强制转换为时间戳的任何其他表达式。
+
+* `COMMENT`：（可选）Table Stream的注释。
+
+* `'TABLE_STREAM_MODE' = 'APPEND_ONLY|STANDARD'`：（必选）值二选一，APPEND\_ONLY和STANDARD。
+
+  * APPEND\_ONLY只记录对象的INSERT操作的数据。Update和delete操作不会记录。例如，最初在表中插入了10行，然后在点位没有移动的时候执行delete操作删除5行，Table Stream仍然记录10行操作。
+  * STANDARD模式：STANDARD模式下可以跟踪源对象的所有DML变化，包括插入、更新和删除（包括表截断）。这种提供行级别的变化是通过将所有变化的delta数据进行连接加工来提供行级别增量。Table Stream中的delta变化指的是在两个事务时间点之间发生的数据变化。例如，如果在Table Stream的offset之后，有一个行被插入，然后被更新，那么delta变化就是一个新的行。如果在stream的offset之后，有一个行被插入，然后被删除，那么delta变化就是没有这个行。换句话说，delta变化会反映源对象的最新状态，而不是历史变化。
+
+* SHOW\_INITIAL\_ROWS:可选参数，指定为TRUE时，创建stream时候记录下table当时的版本，第一次消费该stream，永远拿的是创建时的那个版本，同时第一次消费时，所有数据都是insert模式，第一次消费结束后，后续的行为就和之前行为一样，从某个版本到下次版本之间的Delta数据。
+
+### 注意事项
+
+* 在创建Table Stream之前，必须在基表上执行以下操作：
+
+```SQL
+ALTER TABLE table_name set PROPERTIES ('change_tracking' = 'true');
+```
+
+* TIMESTAMP AS OF指定的最早时间戳取决[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。此参数定义了在被删除数据被保留的时间长度，Lakehouse默认保留数据一天。根据您的业务需求，您可以通过调整 `data_retention_days` 参数来延长或缩短数据的保留周期。请注意，调整数据保留周期可能会影响存储成本。延长保留周期会增加存储需求，从而可能增加相关的费用。
+* 通过实时上传数据写入的数据一分钟之后才可以读取，Table Stream 只能读取已经提交的数据。实时任务写入的数据需要等待 1 分钟才能确认，所以 Table Stream 也要等 1 分钟才能看到。
+
+### 使用案例
+
+案例1：创建APPEND\_ONLY模式的Table Stream
+
+```SQL
+-- 清理环境
+DROP      TABLE IF EXISTS data_change_test;
+
+DROP      TABLE STREAM IF EXISTS data_change_test_stream;
+
+-- 创建测试表
+CREATE    TABLE data_change_test (id int, name string);
+
+INSERT    INTO data_change_test
+VALUES    (1, 'apple');
+
+-- 在data_change_test上创建TABLE stream，获取从当前时间开始插入的增量记录
+ALTER     TABLE data_change_test set PROPERTIES ('change_tracking' = 'true');
+
+CREATE    TABLE STREAM data_change_test_stream ON TABLE data_change_test
+WITH      PROPERTIES ('TABLE_STREAM_MODE' = 'APPEND_ONLY');
+
+-- 插入测试数据
+INSERT    INTO data_change_test
+VALUES    (2, 'banana');
+
+-- 查看STREAM数据
+SELECT    *
+FROM      data_change_test_stream;
+```
+
+案例2：创建STANDARD模式的Table Stream
+
+```SQL
+-- 清理环境
+DROP      TABLE IF EXISTS data_change_test;
+
+DROP      TABLE STREAM IF EXISTS data_change_test_stream;
+
+-- 创建测试表
+CREATE    TABLE data_change_test (id int, name string);
+
+INSERT    INTO data_change_test
+VALUES    (1, 'apple');
+
+-- 在data_change_test上启用change_tracking
+ALTER     TABLE data_change_test set PROPERTIES ('change_tracking' = 'true');
+
+-- 创建STANDARD模式的Table Stream
+CREATE    TABLE STREAM data_change_test_stream ON TABLE data_change_test
+WITH      PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
+
+-- 插入测试数据
+INSERT    INTO data_change_test
+VALUES    (2, 'banana');
+
+-- 更新测试数据
+update data_change_test set name = 'orange'
+WHERE     id = 2;
+
+-- 删除测试数据
+DELETE
+FROM      data_change_test
+WHERE     id = 1;
+
+-- 查看stream数据
+SELECT    *
+FROM      data_change_test_stream;

+
+## Kafka Table Stream
+
+支持在Kafka外部表上创建表流（Table Stream），实现实时消费Topic数据.
+
+#### 语法
+
+```sql
+CREATE TABLE STREAM [IF NOT EXISTS] stream_name 
+ON TABLE external_kafka_table 
+[TIMESTAMP AS OF timestamp_expression]  -- 可选，指定消费起始时间点位
+WITH PROPERTIES (
+  'table_stream_mode' = 'append_only',  -- 仅支持追加模式
+  'show_initial_rows' = 'true'|'false'
+);
+```
+
+### 参数说明
+
+* `TIMESTAMP AS OF`   :指定消费起始时间点（可选），支持格式：
+  * **明确时间戳**：`'2023-01-01 12:00:00'`
+  * **时间函数**：`CURRENT_TIMESTAMP() - INTERVAL '1' HOUR`
+* `show_initial_rows`  :控制初始数据加载行为：
+  * `true`：加载从外部表创建时指定的点位到Table Stream指定的点位之间的历史数据
+  * `false`：从最新点位（`latest`）开始消费，不加载历史数据（默认值）
+* `table_stream_mode`  : 固定为`append_only`，仅处理Kafka新增数据（不支持更新/删除操作）
+
+#### 示例
+
+1. Kafka 外部表创建
+   首先，您需要创建一个 [Kafka 外部表](kafka-external-table.md)。这是创建 Table Stream 的基础。以下是创建 Kafka 外部表的语法：
+
+创建Kafka Connection
+
+```SQL
+CREATE STORAGE CONNECTION pipe_kafka
+    TYPE kafka
+    BOOTSTRAP_SERVERS = ['47.99.48.62:9092']
+    SECURITY_PROTOCOL = 'PLAINTEXT';
+```
+
+创建Kafka外部表
+
+```SQL
+CREATE EXTERNAL TABLE external_table_kafka (   
+ key_column binary,   
+ value_column binary NOT NULL)
+USING kafka
+OPTIONS (    'group_id' = 'external_table_lh',    'topics' = 'test_long')
+CONNECTION pipe_kafka;
+```
+
+* `external_table_kafka` 是外部表的名称。
+* `key_column` 和 `value_column` 分别代表 Kafka 消息的键和值，其中 `value_column` 是必需的。
+* `USING kafka` 指定了使用 Kafka 作为数据源。
+* `OPTIONS` 部分包含了 Kafka 消费者配置，如消费者组 ID (`group_id`) 和要订阅的主题 (`topics`)。
+* `CONNECTION pipe_kafka` 指定了与 Kafka 的连接配置，这通常包括 Kafka 集群的地址和其他连接参数。
+
+2. 创建 Table Stream
+
+在 Kafka 外部表的基础上，您可以创建一个 Table Stream，用于实时处理 Kafka 数据流。以下是创建 Table Stream 的语法：
+
+```
+CREATE TABLE STREAM kafka_table_stream_pipe1
+ ON TABLE external_table_kafka
+WITH PROPERTIES (
+    'table_stream_mode' = 'append_only',
+    'show_initial_rows' = 'true');
+```
+
+^
+
+## Volume Stream
+
+**CREATE VOLUME STREAM 语法**
+
+用于在 External Volume 的 Directory Table 上创建 Volume Stream，以监听外部对象存储中文件的新增与删除事件。
+
+```
+CREATE [OR REPLACE] STREAM [IF NOT EXISTS] <name>
+  ON VOLUME <volume_name>;
+```
+
+**参数说明**
+
+`<name>`：Volume Stream 的名称。
+
+`<volume_name>`：要监听的 External Volume 名称。该 Volume 必须满足以下条件：
+
+* 已开启目录功能，即建表时指定 DIRECTORY = (ENABLE = TRUE)；
+* 已开启递归监听，即建表时指定 RECURSIVE = TRUE。
+
+**示例**
+
+```
+-- 创建Volume Stream，追踪文件新增和删除
+CREATE OR REPLACE STREAM str_app_log
+  ON VOLUME vol_app_log;
+
+```
+
+**注意事项**
+
+* 创建 Volume Stream 之前，须开启 DIRECTORY = (ENABLE = TRUE) 和 RECURSIVE = TRUE 。
+* Volume Stream 本质上是构建在 Directory Table 之上的 Table Stream，消费机制与 Table Stream 完全一致：仅 DML 语句（如 INSERT INTO ... SELECT FROM stream）会推进消费点位，纯 SELECT 查询不会推进。
+* 由于对象存储事件通过消息队列传递存在约 1 分钟的延迟，文件上传后需等待约 1 分钟才能在 Volume Stream 中查询到对应的变更记录。
+

+# 创建计算集群
+
+## 功能描述
+
+本功能允许用户根据指定的名称和配置，在执行SQL的工作空间下创建计算集群。计算集群（Virtual-Cluster，简称：VCluster）是云器Lakehouse提供的计算资源集群服务，提供执行查询分析所需的CPU、内存、临时存储等资源。用户可以使用计算集群执行各类ETL、流式分析、即席查询及数据集成等作业。在Lakehouse中执行需要计算的SQL Select查询或各类DML操作（如DELETE,INSERT,UPDATE等）时，都将使用计算集群。
+
+计算集群包括通用型（GENERAL PURPOSE VIRTUAL CLUSTER，简称：GP类型）、分析型（ANALYTICS PURPOSE VIRTUAL CLUSTER，简称：AP类型）和同步型（INTEGRATION VIRTUAL CLUSTER）三种类型。
+
+通用型计算集群中，提交至计算集群的作业共享集群内的计算资源，适合处理离线作业；分析型集群具备多计算实例、自动弹缩的功能特性，适合处理在线、高并发类的作业。同步型集群专门用于数据集成任务。

+# 通过云器Lakehouse的多表实时同步和动态表实现变化数据捕获（CDC）及数据处理
+
+## 概要介绍
+
+在本快速入门中，我们将研究如何使用存储在 PostgreSQL 数据库中的客户交易数据，通过云器Lakehouse的多表实时同步将数据导入云器Lakehouse的表中，通过动态表进行实时数据处理，并进一步通过云器Lakehouse自带的DataGPT进行可视化数据探索和对话式数据分析，从而实现从数据摄取、数据处理和数据分析的实时全链路，以此来了解客户交易进行洞察分析。
+
+从ELT的角度来看，云器Lakehouse的多表实时同步实现了基于CDC的数据抽取（Data Extraction）和加载（Load），并且在该过程中实现了模式演进（Schema Evolution），也就是同步内容会包括源数据库的结构或模式（Schema）的变化。动态表Dynamic Table则以全新的方式实现了数据转换（Data Transform）。

+在本节中，我们将建立一个 PostgreSQL 数据库并创建表来模拟金融公司的客户交易数据。
+
+### 启动数据库实例
+
+在开始此步骤之前，请确保已为[Mac](https://docs.docker.com/desktop/install/mac-install/)、[Windows](https://docs.docker.com/desktop/install/windows-install/)或[Linux](https://docs.docker.com/desktop/install/linux/)安装了 Docker Desktop 。确保您的机器上已安装[Docker Compose 。](https://docs.docker.com/compose/install/)
+
+1. 要使用 Docker 启动 PostgreSQL 数据库，您需要创建一个名为docker-compose.yaml的文件。此文件将包含 PostgreSQL 数据库的配置。如果您有另一个容器客户端，请启动容器并使用下面的 PostgreSQL 映像。
+2. 打开您选择的 IDE（比如VS Code），通过复制并粘贴以下内容来复制并粘贴此文件：
+
+```YAML
+services:
+  postgres:
+    image: "postgres:17"
+    container_name: "postgres17"
+    environment:
+      POSTGRES_DB: 'postgres'
+      POSTGRES_USER: 'postgres'
+      POSTGRES_PASSWORD: 'postgres'
+    ports:
+      - "5432:5432"
+    command:
+      - "postgres"
+      - "-c"
+      - "wal_level=logical"
+    volumes:
+      - ./postgres-data:/var/lib/postgresql/data
+```
+
+3. 打开终端并导航到docker-compose.yaml文件所在的目录。运行以下命令启动 PostgreSQL 数据库：
+
+```Shell
+docker-compose up -d
+```
+
+### 连接数据库
+
+要使用 Visual Studio Code 或 DBV/DBGrid/PyCharm 或您选择用于数据库连接的任何 IDE 连接到预配置的数据库，请使用提供的凭据执行以下步骤：
+
+1. 打开您选择的工具以连接 PostgreSQL 数据库
+
+   1. 对于 VSCode，你可以使用[PostgreSQL 扩展](https://marketplace.visualstudio.com/items?itemName=cweijan.vscode-postgresql-client2)
+   2. 对于 PyCharm，您可以使用[数据库工具和 SQL 插件](https://www.jetbrains.com/help/pycharm/database-tool-window.html)
+
+2. 单击`+`符号或类似符号以添加数据源
+
+3. 使用这些连接参数：
+
+   1. 用户：`postgres`
+   2. 密码：`postgres`
+   3. 网址：`jdbc:postgresql://localhost:5432/`
+
+4. 测试连接并保存
+
+5. 为了能让云器Lakehouse Studio通过公网访问到Postgres数据库，务必给Postgres数据库做公网NAT映射。
+
+### 加载数据
+
+1. 在 PostgreSQL 中运行以下[postgres脚本](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/scripts/postgresql_setup.sql)来创建数据库、模式和表：
+
+```SQL
+CREATE SCHEMA raw_cdc;
+SET search_path TO raw_cdc;
+
+DROP TABLE IF EXISTS postgres.raw_cdc.customers;
+DROP TABLE IF EXISTS postgres.raw_cdc.merchants;
+DROP TABLE IF EXISTS postgres.raw_cdc.products;
+DROP TABLE IF EXISTS postgres.raw_cdc.transactions;
+
+CREATE TABLE postgres.raw_cdc.customers (
+   customer_id INTEGER PRIMARY KEY,
+   firstname VARCHAR,
+   lastname VARCHAR,
+   age INTEGER,
+   email VARCHAR,
+   phone_number VARCHAR
+);
+
+CREATE TABLE postgres.raw_cdc.merchants (
+   merchant_id integer PRIMARY KEY,
+   merchant_name VARCHAR,
+   merchant_category VARCHAR
+);
+
+CREATE TABLE postgres.raw_cdc.products (
+   product_id INTEGER PRIMARY KEY,
+   product_name VARCHAR,
+   product_category VARCHAR,
+   price DOUBLE PRECISION
+);
+
+CREATE TABLE postgres.raw_cdc.transactions (
+   transaction_id VARCHAR PRIMARY KEY,
+   customer_id INTEGER,
+   product_id INTEGER,
+   merchant_id INTEGER,
+   transaction_date DATE,
+   transaction_time VARCHAR,
+   quantity INTEGER,
+   total_price DOUBLE PRECISION,
+   transaction_card VARCHAR,
+   transaction_category VARCHAR
+);
+```
+
+2. 下载这些 csv 文件并将其保存到本地计算机的目录中：
+
+   1. [客户.csv](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/postgres_csv/customers.csv)
+   2. [商家.csv](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/postgres_csv/merchants.csv)
+   3. [产品.csv](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/postgres_csv/products.csv)
+   4. [交易.csv](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/postgres_csv/transactions.csv)
+
+3. Postgres数据加载方式1，通过PG的Copy命令加载
+
+   1. 在将数据加载到 PostgreSQL 数据库之前，我们需要将文件从本地计算机移动到 Docker 容器。
+   2. 导航到您的终端，使用以下命令获取 Docker 容器 ID：
+   3. ```Shell
+      docker ps
+      ```
+   4. 要将 CSV 文件复制到容器，请在终端中运行以下命令，将文件路径替换为实际文件路径，并将其替换`container_id`为上一个命令中的实际容器 ID：
+   5. ```Shell
+      docker cp /Users/your_username/Downloads/customers.csv container_id:/tmp/customers.csv
+      docker cp /Users/your_username/Downloads/merchants.csv container_id:/tmp/merchants.csv
+      docker cp /Users/your_username/Downloads/products.csv container_id:/tmp/products.csv
+      docker cp /Users/your_username/Downloads/transactions.csv container_id:/tmp/transactions.csv
+      ```
+   6. 返回 PostgreSQL 控制台，运行以下 SQL 命令将文件从容器加载到 PostgreSQL 表：
+
+```SQL
+COPY postgres.raw_cdc.customers FROM '/tmp/customers.csv' DELIMITER ',' CSV HEADER;
+COPY postgres.raw_cdc.merchants FROM '/tmp/merchants.csv' DELIMITER ',' CSV HEADER;
+COPY postgres.raw_cdc.products FROM '/tmp/products.csv' DELIMITER ',' CSV HEADER;
+COPY postgres.raw_cdc.transactions FROM '/tmp/transactions.csv' DELIMITER ',' CSV HEADER;
+```
+
+4. Postgres数据加载方式2，通过Python脚本加载
+
+将以下代码Copy进Python文件或者Notebook然后运行，也可以直接下载[这个Python文件](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/scripts/load-data-into-pg-by-python.py)。
+
+```Python
+import psycopg2
+
+# 数据库连接信息
+conn = psycopg2.connect(
+    dbname="postgres",
+    user="postgres",
+    password="postgres",
+    host="localhost",
+    port="5432"
+)
+cur = conn.cursor()
+# 设置 search_path 
+cur.execute("SET search_path TO raw_cdc;")
+import os
+# 设置 CSV 文件目录
+csv_directory = "csv/"
+
+def load_csv_to_postgres(csv_file, table_name):
+    with open(csv_file, 'r') as f:
+        cur.copy_expert(f"COPY {table_name} FROM STDIN WITH CSV HEADER DELIMITER ','", f)
+    conn.commit()
+
+# 遍历目录中的所有 CSV 文件并加载到对应的表中
+for filename in os.listdir(csv_directory):
+    if filename.endswith(".csv"):
+        csv_file = os.path.join(csv_directory, filename)
+        table_name = os.path.splitext(filename)[0]  # 文件名去掉扩展名作为表名
+        print(f"Loading {csv_file} into table {table_name}...")
+        load_csv_to_postgres(csv_file, table_name)
+        print(f"Loaded {csv_file} into table {table_name} successfully!")
+# 关闭游标和连接
+cur.close()
+conn.close()
+```
+
+5. 接下来，确保运行`CREATE PUBLICATION`命令以启用模式中表的逻辑复制`raw_cdc`。这将允许下文的实时同步任务捕获对 PostgreSQL 数据库中表所做的更改：
+
+```SQL
+CREATE PUBLICATION agent_postgres_publication FOR ALL TABLES;
+```
+
+发布（Publication）是 PostgreSQL 逻辑复制的一部分，它允许用户定义一组表的变更（插入、更新、删除），这些变更将被传送给一个或多个订阅者（Subscribers）。逻辑复制是 CDC 的一种实现方式，它捕获并传播数据库表中的数据变更。换句话说，执行这条语句之后，PostgreSQL 会捕获数据库中所有表的数据变更，并且这些变更可以被订阅者接收和处理。从而实现 CDC 的数据变化记录。
+
+6. 最后，通过运行以下 SQL 命令检查表是否已正确加载：
+
+```SQL
+SELECT * FROM postgres.raw_cdc.customers;
+SELECT * FROM postgres.raw_cdc.merchants;
+SELECT * FROM postgres.raw_cdc.products;
+SELECT * FROM postgres.raw_cdc.transactions;
+```
+
+## 创建并启动云器Lakehouse CDC多表实时同步任务
+
+### 概述
+
+您将使用[云器Lakehouse Studio](https://accounts.clickzetta.com/)来基于界面操作、以无代码的方式来创建多表实时同步任务，将数据从Postgres的表加载到云器Lakehouse的表中。
+
+### 创建Postgres数据源
+
+导航到管理->数据源，单击“新建数据源”并选择Postgres以创建Postgres数据源，使得Postgres能被云器Lakehouse可访问。
+
+:-: ![](.topwrite/assets/image_1735115653296.png =600)
+
+^
+
+:-: ![](.topwrite/assets/image_1735115660694.png =600)
+
+* 数据源名称：PG\_CDC\_DEMO
+* 连接参数：同上节Postgres环境连接参数。
+* 请注意务必配置正确的数据库所在的时区，避免数据同步失败。
+
+### 创建多表实时同步任务
+
+导航到开发->任务，单击`+`以创建新工作目录和工作表任务，然后选择“多表实时同步”。
+
+* 选择“多表实时同步”：
+
+:-: ![](.topwrite/assets/image_1735115675871.png =600)
+
+创建多表实时同步任务并存放在刚才构建环境的同一个目录里：
+
+* 任务名称：02\_Ingestion\_CDC
+* 来源数据：选择Postgres
+
+:-: ![](.topwrite/assets/image_1735115689339.png =600)
+
+  来源数据选择上一步创建的Postgres数据源：PG\_CDC\_DEMO,选择之后会自动显示该数据源可访问的数据库、Schema和表，并选中所有表（所有表都需要同步）：
+
+:-: ![](.topwrite/assets/image_1735115698983.png =624)
+
+  选择或者新建CDC同步的SlotName，请注意同一个Slot不要被两个任务共享消费，以免数据丢失：
+
+:-: ![](.topwrite/assets/image_1735115710124.png =600)
+
+  目标表配置：
+
+  选择目标数据源下已有的Schema作为目标表存储位置。
+
+:-: ![](.topwrite/assets/image_1735115718468.png =663)
+
+  配置并检查表、字段映射关系：
+
+  云器Lakehouse会自动形成表和字段的映射，包括数据类型的映射。如果选中的云器Lakehouse命名空间里没有对应的表，多表实时同步任务在任务启动时会自动检查并新建表，无需手动提前创建。
+CDC同步要求在源端表都有主键，多表实时同步会在Lakehouse目标表里自动创建对应的[主键](primary-key.md)。
+
+:-: ![](.topwrite/assets/image_1735115731100.png =641)
+
+  
+
+配置同步规则：
+
+  Schema Evolution，即“模式演进”，是指在数据库管理系统中，随着时间的推移和需求的变化，数据库的结构或模式（Schema）进行修改和适应的过程。模式演变通常涉及对数据库表结构、字段、数据类型、关系和约束的更改，而这些更改不会中断现有系统的运行或导致数据丢失。
+
+  实时同步任务的同步规则中，可以配置对于源端表和字段的变更的自动处理策略：
+
+* 设置来源表删除字段后的行为。
+* 设置来源表新增字段的行为。重命名字段视为字段删除、命名后字段被识别为字段新增。
+* 设置来源表新增字段后的行为。
+* 设置数据源同步对象被删除的行为。重命名表视为删除，重命名后的表视为新建表。
+
+  此外，同步规则中也支持设定需要处理的源端变更消息的类型，请按需设定。比如某些场景下，期望目标端的数据一直累加，不处理源端“删除”变更，在改配置中去除掉“删除”选项即可。
+
+:-: ![](.topwrite/assets/image_1735115747197.png =652)
+
+### 提交多表实时同步任务并启动
+
+* **提交**多表实时同步任务：
+
+:-: ![](.topwrite/assets/image_1735115761930.png =600)
+
+* **运维**多表实时任务：
+
+:-: ![](.topwrite/assets/image_1735115774424.png =600)
+
+* **启动**多表实时任务：
+
+:-: ![](.topwrite/assets/image_1735115784817.png =600)
+
+* 并选择“全量数据同步”：
+
+是否在增量同步前，先进行全量的数据同步。请注意，此配置只在任务上线后第一次启动可以选择。
+
+:-: ![](.topwrite/assets/image_1735115795219.png =474)
+
+### 查看全量同步状态
+
+在上文的“Postgres环境”步骤，已经通过Copy或者Python脚本方式，往Postgres的四张表中加载了数据。上一步选择的“全量数据同步”，在增量数据同步开始前，实现全量数据的同步。
+
+:-: ![](.topwrite/assets/image_1735115806467.png =613)
+
+全部4张表的全量同步状态和增量同步状态都正常，没有发生Failover。
+
+:-: ![](.topwrite/assets/image_1735115814661.png =789)
+
+可以看到全量同步已经完成，此后，增量同步状态会自动转换成“正在同步”，不需要人工干预操作。
+
+## 多表实时同步的增量同步过程
+
+### 在数据源插入新增数据
+
+在Postgres的源表中插入数据，通过已启动的实时多表同步任务实现增量数据同步，并查看实时多表同步任务的同步状态。
+
+多表实时同步在增量同步过程中，使用了Lakehouse的[Java实时编程接口](java_reference/realtime-upload.md)将数据实时写入Lakehouse的主键表中。
+
+将以下代码Copy进Notebook并运行，或者[直接下载](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/scripts/pg-insert-transaction.ipynb)：

+
+## 通过动态表处理多表实时同步进来的数据
+
+概述
+
+您将使用[云器Lakehouse Studio](https://accounts.clickzetta.com/)来创建动态表（Dynamic Table），将从Postgres的表通过多表实时同步到云器Lakehouse的数据进行实时处理。
+
+### 创建动态表
+
+导航到开发->任务，单击“+选择“动态表”。
+
+:-: ![](.topwrite/assets/image_1735115842636.png =600)
+
+* 任务名称：03\_customer\_purchase\_summary
+* Schema选择：real\_time\_financial\_insights\_using\_change\_data\_capture\_cdc
+* 表名请输入：customer\_purchase\_summary
+* 在SQL代码里输入：
+
+```Python
+SELECT
+    t.transaction_id
+    , t.customer_id
+    , c.age AS customer_age
+    , t.product_id
+    , p.product_name
+    , p.product_category
+    , t.merchant_id
+    , m.merchant_name
+    , m.merchant_category
+    , t.transaction_date
+    , t.transaction_time
+    , t.quantity
+    , t.quantity * p.price AS total_price
+    , t.transaction_card
+    , t.transaction_category
+FROM
+    transactions t
+JOIN
+    customers c ON t.customer_id = c.customer_id
+JOIN
+    products p ON t.product_id = p.product_id
+JOIN
+    merchants m ON t.merchant_id = m.merchant_id
+AND
+    m.merchant_category = p.product_category;
+```
+
+  这段 SQL 查询的具体作用是通过多个表的连接，从 `transactions` 表中获取详细的交易记录，并从 `customers`、`products` 和 `merchants` 表中获取相关的信息。以下是详细的解释：
+
+  
+
+* **从** \*\*\*\*\`\`\*\* 表中提取交易记录\*\*：
+
+  * `t.transaction_id`：获取每笔交易的唯一标识符。
+  * `t.customer_id`：获取与交易相关联的客户的标识符。
+  * `t.product_id`：获取交易中涉及的产品的标识符。
+  * `t.merchant_id`：获取提供产品或服务的商家的标识符。
+  * `t.transaction_date` 和 `t.transaction_time`：获取交易发生的日期和时间。
+  * `t.quantity`：获取交易中购买的产品数量。
+  * `t.transaction_card`：获取用于交易的卡类型（如信用卡或借记卡）。
+  * `t.transaction_category`：获取交易的类别（例如购买或退款）。
+
+  
+
+* **从** \*\*\*\*\`\`\*\* 表中提取客户信息\*\*：
+
+  * 使用 `JOIN customers c ON t.customer_id = c.customer_id` 将 `transactions` 表与 `customers` 表连接，获取与交易相关联的客户信息。
+  * `c.age AS customer_age`：获取客户的年龄，并将其命名为 `customer_age`。
+
+  
+
+* **从** \*\*\*\*\`\`\*\* 表中提取产品信息\*\*：
+
+  * 使用 `JOIN products p ON t.product_id = p.product_id` 将 `transactions` 表与 `products` 表连接，获取交易中涉及的产品信息。
+  * `p.product_name`：获取产品的名称。
+  * `p.product_category`：获取产品的类别。
+  * `t.quantity * p.price AS total_price`：计算每笔交易的总价格（数量乘以产品单价），并将其命名为 `total_price`。
+
+  
+
+* **从** \*\*\*\*\`\`\*\* 表中提取商家信息\*\*：
+
+  * 使用 `JOIN merchants m ON t.merchant_id = m.merchant_id AND m.merchant_category = p.product_category` 将 `transactions` 表与 `merchants` 表连接，并确保商家的类别与产品类别匹配。
+  * `m.merchant_name`：获取商家的名称。
+  * `m.merchant_category`：获取商家的类别。
+
+通过这些连接和数据提取，这段查询语句生成了一个详细的结果集，每条记录包含交易的详细信息、客户信息、产品信息和商家信息，并计算了每笔交易的总价格，从而获得更全面和深入的交易分析。
+
+动态表则会直接根据生命式语法，按照要求定时刷新数据，从而达到数据动态变化的目的。

+# 概述
+
+数据同步是云器 Lakehouse 内置的高效数据集成服务，支持在多种数据源之间同步数据，并利用调度系统创建自动化的同步任务。通过数据同步功能，用户无需编写代码，只需通过简单的向导式操作即可实现快速导入 Lakehouse、导出加工后数据或进行不同数据源之间的数据同步。
+
+^
+
+## 基本概念
+
+### 数据同步任务
+
+数据同步任务是用于从数据源采集数据并写入目标数据源的一种任务类型。根据数据同步的时效性，数据同步任务可分为离线同步任务和实时同步任务。在 Lakehouse Studio 中，数据同步任务通过界面配置实现任务定义和调度配置，无需编写代码。
+
+Lakehouse Studio 目前支持离线周期同步和实时同步两大类同步任务类型。在“开发 > 任务”中点击新建按钮，按需选择合适的任务类型。
+
+![](.topwrite/assets/image_1736153630510.png =600)
+
+^
+
+一个数据同步任务包含以下核心组件：
+
+1.  **数据来源**：同步任务的数据来源，包括数据库、文件系统、SaaS/应用、Lakehouse 空间数据源等。数据来源由数据源进行定义和管理。
+2.  **数据对象**：同步任务需要处理的数据来源下的数据对象，如数据库表、消息队列 Topic、文件系统文件等。
+3.  **对象及 Schema 映射**：定义来源数据对象与目标数据对象及其 Schema 之间的映射关系。
+4.  **数据目标**：数据写入的目标数据源，包括 Lakehouse 及其他外部数据源。
+5.  **任务设置**：影响任务运行的规则设置，如容错规则、并发设置、流量控制等。
+6.  **调度配置**：任务调度运行的规则及策略。
+
+### 数据源
+
+数据源是定义外部服务连接信息的对象，包括服务地址、认证信息、连接方式等。定义好的数据源可以在数据同步任务中作为数据来源或数据目标使用。数据源位于“管理 > 数据源”功能菜单下。
+
+![](.topwrite/assets/image_1736153771696.png =800)
+
+^
+
+## 使用示例
+
+### 示例：从MySQL数据库同步数据到Lakehouse
+
+假设您有一个 MySQL 数据库，其中包含客户订单数据。您希望将这些数据同步到 Lakehouse，以便进行数据分析和处理。
+
+1.  在 Lakehouse 中创建一个新的数据同步任务。
+2.  选择 MySQL 数据库作为数据来源，并指定相应的数据源连接信息。
+3.  选择需要同步的数据库表作为数据对象。
+4.  定义表结构及字段映射规则。
+5.  选择 Lakehouse 作为数据目标，并指定目标表。
+6.  根据需要配置任务设置和调度配置。
+7.  启动同步任务，数据将按照设定的规则从 MySQL 数据库同步到 Lakehouse。
+
+通过以上示例，您可以看到 Lakehouse 数据同步功能可以帮助您轻松实现不同数据源之间的数据同步，无需编写复杂的代码。这将大大提高数据处理效率，让您专注于数据分析和业务决策。

+# 数据生命周期
+
+数据生命周期（TTL）是指云器 Lakehouse 中表和表分区从最后一次更新时间算起的时间长度。在指定的时间周期内，如果数据没有发生变动，系统将自动回收这些数据。生命周期的单位是天，且取值为整数类型。
+
+## 数据生命周期的工作原理
+
+数据生命周期到期的回收依赖于数据的最后修改时间（last\_modified\_time）。对于非分区表，您可以通过 `desc extended` 命令查看 last_modified_time；对于分区表，您可以通过 `SHOW PARTITIONS EXTENDED table_name` 查看对应具体分区的 last_modified_time。当发生 DDL（数据定义语言）或 DML（数据操纵语言）操作时，last_modified_time 会更新。
+
+需要注意的是，到期的数据并不会立即被回收。您仍然可以查询这些数据，直到后台进程执行删除操作。通常，后台进程会在 24 小时内删除这些数据。此外，被回收的表仍然遵守 [数据保留周期](TIMETRAVEL.md)，您仍可以使用 [时间旅行](TIMETRAVEL.md) 功能进行查询。若需要恢复已删除的对象，可以使用 [undrop table](UNDROP-TABLE.md) 命令。
+
+## 设置数据生命周期
+
+生命周期单位为天，取值为正整数。设置为 '-1' 代表不开启生命周期，即数据将被永久保留。您可以在创建表时指定生命周期，也可以在表创建后进行修改。
+
+### 具体SQL操作方式
+
+**创建表时设置生命周期**
+
+```SQL
+-- 创建表并设置生命周期为7天
+CREATE TABLE tname (col1 datatype1, col2 datatype2) PROPERTIES('data_lifecycle'='7');
+-- 创建表并设置生命周期为7天，同时在生命周期到期时删除表结构
+CREATE TABLE tname (col1 datatype1, col2 datatype2) PROPERTIES('data_lifecycle'='7', 'data_lifecycle_delete_meta'='true');
+```
+
+**修改现有表的生命周期**
+
+```SQL
+-- 修改表的生命周期为10天
+ALTER TABLE tname SET PROPERTIES ('data_lifecycle'='10');
+-- 修改表的生命周期为10天，并在生命周期到期时删除表结构
+ALTER TABLE tname SET PROPERTIES ('data_lifecycle'='10', 'data_lifecycle_delete_meta'='true');
+```
+
+## 注意事项
+
+1.  生命周期回收任务每天不定时启动，每 12 小时轮询一次，会扫描全量分区。只有当 last_modified_time 超过生命周期指定的时间时，数据才会被回收。
+2.  生命周期回收主要针对表或分区，每天根据服务的繁忙程度进行，不能确保到期后立即被回收。
+3.  生命周期到期时，默认行为是不删除表结构，只清空数据。如果您希望删除表结构，请在设置生命周期时添加参数 `ALTER TABLE tname SET PROPERTIES ('data_lifecycle_delete_meta'='true')`。
+4.  修改生命周期时，例如当您将生命周期策略从 15 天更改为 30 天时，新策略会立即生效。但是由于生命周期回收任务每天不定时启动，通常每 12 小时轮询一次。在极少数情况下，如果在策略变更时，回收任务恰好启动并读到了旧的策略，可能会按照旧策略（15 天）回收部分数据。该现象属于系统设计的正常机制，不会影响未到期数据的安全。

+
+Lakehouse 从原理上提供了两种主要的数据写入方法，以适应不同的数据处理需求和性能考量。
+
+### **SQL 引擎直接拉取**
+
+Lakehouse 的 SQL 引擎能够直接从对象存储中拉取数据，这一方法特别适合于数据源已经位于对象存储的场景。未来，Lakehouse 计划扩展支持更多类型的数据源，以进一步提升数据接入的灵活性。
+
+* **优势**：SQL 引擎直接拉取数据，利用其性能优势，可以高效地处理存储在对象存储中的数据。使用 COPY 命令、Volume 可在导入过程中进行数据转换。
+* **计算资源**：执行 SQL 查询时会消耗计算资源（Virtual Cluster），但这种消耗是值得的，因为它提供了强大的数据处理能力。
+* **文件格式**：目前支持的文件格式包括 CSV、PARQUET 和 ORC，这些格式都是数据分析和处理中常用的格式。
+* **导入方式**：支持多种数据导入方式，如 COPY 命令、Volume、数据集成离线导入以及 SDK 批量上传（BulkloadStream）。
+
+### 向Ingestion Service推送数据
+
+Lakehouse 的 Ingestion Service 为需要实时数据写入的场景提供了解决方案。客户端将数据推送到服务端，由 Ingestion Service 接收并提交到表中，包括 SDK 实时数据流（RealtimeStream）和 CDC 实时写入。
+
+* **优势**：提高了数据写入的时效性，实现了实时写入和实时可读。
+* **资源消耗**：目前 Ingestion Service 处于预览版，使用该服务暂不计费。但请注意，未来将开始计费。
+* **适用场景**：适用于需要实时数据流处理的业务场景，如实时分析和即时数据更新。
+
+# 批量加载建议
+
+批量摄取涉及加载不需要实时处理的大型有界数据集。这些数据通常以特定的频率被摄取，并非所有数据都立即到达。对于批量加载，建议使用对象存储来存储传入数据。Lakehouse 支持多种文件格式，包括 CSV、Parquet、ORC。

+# Lakehouse Time Travel 功能使用指南
+
+## Time Travel功能简介
+
+Lakehouse 的 Time Travel 功能让您能够轻松访问时间旅行窗口内任何时间点的数据。这意味着您可以在不同的时间点查看数据，甚至可以恢复到先前的数据状态。
+
+借助 Time Travel，您可以查询已更新或删除的数据、恢复已删除的表或者恢复已过期的表。
+![](.topwrite/assets/image_1708936936399.png =740)
+
+如上图所示，表中原来有一条数据，对表执行 INSERT、UPDATE、DELETE 等操作后，一共有四个版本。当指定的时间点或版本在 v0 到 v1 之间时，则会返回 v0 的数据。通过 Time Travel 指定时间点或版本可以查看历史版本数据。
+
+## 访问特定时间点的数据
+
+[TIME TRAVEL](TIMETRAVEL.md)
+
+## 设置数据保留周期
+
+您可以配置 Time Travel 的数据保留周期，以决定数据在时间旅行窗口中保留的时间长度。根据您的需求，您可以设置不同的保留期限。
+
+Time Travel 保留期限决定了您可以访问多久以前的数据。例如，如果 Time Travel 保留期限设置为 7 天，那么您可以访问过去 7 天内任何时间点的数据。如果超过了 7 天，您将无法再使用 Time Travel 访问过期的数据，数据会被物理删除。
+
+当前版本中，默认保留周期是 1 天，可以查询 1 天内的数据。
+
+### 在表上设置数据保留周期
+
+您可以通过以下SQL语句设置表的数据保留周期：
+
+```SQL
+ALTER TABLE orders SET PROPERTIES ('data_retention_days'='num');
+```
+
+其中 `num` 的设置范围为 0-90，表示数据保留的天数。
+
+## 恢复已删除的对象
+
+如果您意外删除了某个对象，可以使用 `UNDROP` 命令来恢复它。以下是一个恢复已删除表的示例：
+
+```SQL
+UNDROP TABLE orders;
+```
+
+此命令将恢复名为 `orders` 的已删除表。
+
+## 恢复到指定版本的数据
+
+使用 `RESTORE` 命令，您可以将数据恢复到特定版本。这对于回滚或修复错误的数据更改非常有用。以下是一个将数据恢复到指定版本的示例：
+
+```SQL
+RESTORE TABLE orders TO TIMESTAMP AS OF '2023-03-01 10:00:00';
+```
+
+此命令将 `orders` 表的数据恢复到 2023年3月1日 10:00:00 的版本。

+# TIMESTAMP\_NTZ
+
+## 概述
+
+timestamp\_ntz即timestamp without time zone 是一种数据库数据类型，用于存储不包含时区信息的日期和时间值。这意味着存储的时间值是绝对的，不考虑时区的变化。无论用户在哪个时区，timestamp without time zone 类型的字段显示的时间都是一样的,使用 timestamp without time zone 类型时，通常需要应用程序或用户自己来管理时区转换，因为数据库不会自动处理时区信息。这种类型适用于那些不需要考虑时区差异的场景。timestamp\_ntz等效于Mysql中的datetime。
+
+## 语法
+
+```SQL
+TIMESTAMP_NTZ
+```
+
+**说明**
+
+`timestamp_ntz` 类型当前支持 JDBC 客户端版本 1.4.0 及以上的 JDBC JAR 包
+
+### timestamp\_ntz常量格式
+
+```SQL
+TIMESTAMP_NTZ
+
+timestampString
+{ 'yyyy[...]' |
+  'yyyy[...]-[M]M' |
+  'yyyy[...]-[M]M-[d]d' |
+  'yyyy[...]-[M]M-[d]d ' |
+  'yyyy[...]-[M]M-[d]d[T][H]H[:]' |
+  'yyyy[..]-[M]M-[d]d[T][H]H:[m]m[:]' |
+  'yyyy[...]-[M]M-[d]d[T][H]H:[m]m:[s]s[.]' |
+  'yyyy[...]-[M]M-[d]d[T][H]H:[m]m:[s]s.[ms][ms][ms][us][us][us]' }
+```
+
+* `yyyy`：一个至少包含四位数字的年份。
+* `[M]M`：介于 01 和 12 之间的一位数或两位数的月份。
+* `[d]d`：介于 01 和 31 之间的一位数或两位数的日期。
+* `H[H]`：介于 00 和 23 之间的一位数或两位数的小时。
+* `m[m]`：介于 00 和 59 之间的一位数或两位数的分钟。
+* `s[s]`：介于 00 和 59 之间的一位数或两位数的秒。
+* `[ms][ms][ms][us][us][us]`：秒最多 6 位小数。
+
+```SQL
+SELECT TIMESTAMP_NTZ'2020-12-31';
++---------------------------+
+| TIMESTAMP_NTZ'2020-12-31' |
++---------------------------+
+| 2020-12-31 00:00:00       |
++---------------------------+
+SELECT TIMESTAMP_NTZ'2021-7-1T8:43:28.123456' as res;
++----------------------------+
+|            res             |
++----------------------------+
+| 2021-07-01 08:43:28.123456 |

++----------------------------+
+| 2021-07-01 08:43:28.123456 |
++----------------------------+
+```
+
+如果输入的字符串中的格式则会转化为timestmap
+
+## timestamp\_ntz和timestamp\_ltz的区别
+
+timestamp\_ntz（没有时区的时间戳）: 这种类型的时间戳记录的是“墙上时钟”时间，即不考虑任何时区信息的时间。所有的操作都是在没有考虑时区的情况下进行的。如果输出格式包含时区，将显示UTC指示符（Z）。这意味着，无论你在世界上的哪个地方，timestamp\_ntz记录的时间都是相同的。
+
+timestamp\_ltz（本地时区的时间戳）: 这种类型的时间戳在内部存储UTC时间，并根据当前会话的时区进行所有操作。这意味着，当你查询一个timestamp\_ltz类型的字段时，你看到的时间将是转换为你当前会话时区的时间。这使得在全球分布的系统中工作时，用户可以看到转换为他们本地时区的时间。
+
+如下所示：本地客户端的时区为utc+00区。timestamp\_ltz会根据字符输入的时区进行转化内部存储UTC时间，由于客户端也在utc+00区，所以查出来会转化为utc+00时间。而timestamp\_ntz不考虑任何时区所以客户端在任何时区查出来都是该时间
+
+```SQL
+SELECT timestamp_ltz'2022-03-30 06:00:00+08',timestamp_ntz'2022-03-30 06:00:00+08';
++---------------------------------------+---------------------------------------+
+| timestamp_ltz'2022-03-30 06:00:00+08' | timestamp_ntz'2022-03-30 06:00:00+08' |
++---------------------------------------+---------------------------------------+
+| 2022-03-29 22:00:00                   | 2022-03-30 06:00:00                   |
++---------------------------------------+---------------------------------------+
+```
+
+## 约束限制
+
+* 不支持python sdk写入timestamp\_ntz
+
+## 具体案例
+
+1. 将timestmap\_ntz转化为timestmap\_ltz
+
+```SQL
+SELECT cast(timestamp_ntz'2022-03-30 06:00:00' as timestamp_ltz);
++-------------------------------------------------------+
+| CAST(timestamp_ntz'2022-03-30 06:00:00' AS timestamp) |
++-------------------------------------------------------+
+| 2022-03-30 06:00:00                                   |
++-------------------------------------------------------+
+```
+
+2. 将timestmap\_lt转化为timestmap\_ntz
+
+```SQL
+SELECT cast(timestamp_ltz'2022-03-30 06:00:00+08' as timestamp_ntz);
++--------------------------------------------------------------+
+| CAST(timestamp_ltz'2022-03-30 06:00:00+08' AS timestamp_ntz) |
++--------------------------------------------------------------+
+| 2022-03-30 06:00:00                                          |
++--------------------------------------------------------------+
+```
+
+3. 建表时使用timestamp\_ntz字段数据类型
+
+```SQL
+CREATE    TABLE timestamp_wihtout_timezone (col timestamp_ntz);
+```
+
+4. 插入timestamp\_ntz类型数据
+
+```SQL
+INSERT    INTO timestamp_wihtout_timezone
+VALUES    (timestamp_ntz '2022-03-30 06:00:00');
+```
+
+5. 使用函数处理
+
+```SQL
+SELECT    year(timestamp_ntz '2022-03-30 06:00:00');
++--------------------------------------------+
+| `year`(timestamp_ntz'2022-03-30 06:00:00') |
++--------------------------------------------+
+| 2022                                       |
++--------------------------------------------+
+SELECT    month(timestamp_ntz '2022-03-30 06:00:00');
++---------------------------------------------+
+| `month`(timestamp_ntz'2022-03-30 06:00:00') |
++---------------------------------------------+
+| 3                                           |
++---------------------------------------------+

+# 编写SQL对数据进行清洗
+
+在数据分析和数据挖掘的过程中，数据清洗和预处理是至关重要的一步。本文将介绍各种常用的Lakehouse SQL数据清洗方法，帮助您更好地理解和应用这些方法。
+
+## 构建环境
+
+导航到Lakehouse Studio开发->任务，单击“+”新建一个SQL任务（以下两种方式都在同一个任务里实现）。
+
+:-: ![](.topwrite/assets/image_1736148597217.png =470)
+
+^
+
+新建两个SQL任务（如下图所示），然后从[GitHub获取代码](https://github.com/yunqiqiliang/clickzetta_quickstart/tree/main/QuickStart_SQL_DataClean)下载SQL代码并复制到两个任务中。
+
+然后逐一运行每个SQL，观察结果。
+
+:-: ![](.topwrite/assets/image_1736402851987.png =471)
+
+以下是各个步骤的说明。
+
+## 构建实验用的Schema和计算集群
+
+```SQL
+-- Data_Clean virtual cluster
+CREATE VCLUSTER IF NOT EXISTS Data_Clean
+   VCLUSTER_SIZE = XSMALL
+   VCLUSTER_TYPE = GENERAL
+   AUTO_SUSPEND_IN_SECOND = 60
+   AUTO_RESUME = TRUE
+   COMMENT  'Data_Clean VCLUSTER for test';
+
+-- Use our VCLUSTER
+USE VCLUSTER Data_Clean;
+
+-- Create and Use SCHEMA
+CREATE SCHEMA IF NOT EXISTS  Data_Clean;
+USE SCHEMA Data_Clean;
+```
+
+> 注：计算集群的vcluster\_size参数同时支持以T-shirt size（XSMALL、SMALL、Large等）和以数字（1,2,4,16等）表达的方式，以提供更丰富的计算集群规格，满足不同场景的需要。更多信息详见：[计算集群规格代码变更说明](vcluster_size_description.md)
+
+## 将IDE中每个任务的Schema和集群设置为新创建的：

+
+## 处理缺失值
+
+### 说明
+
+缺失值是数据清洗中常见的问题，它会导致数据分析结果不准确。可以使用 `COALESCE` 函数、`IFNULL` 函数或者 `CASE` 语句填充默认值或替换缺失值。在实际项目中，处理缺失值常用于确保关键字段不为空，以保证数据的完整性。
+
+### 实现
+
+```sql
+-- 使用 COALESCE 填充默认值
+SELECT id, sale_date, COALESCE(customer_id, 0) AS customer_id, product_id, quantity, price, COALESCE(total_amount, 0) AS total_amount, region FROM sales_data;
+
+-- 使用 IFNULL 填充默认值
+SELECT id, sale_date, IFNULL(customer_id, 0) AS customer_id, product_id, quantity, price, IFNULL(total_amount, 0) AS total_amount, region FROM sales_data;
+
+-- 使用 CASE 语句处理缺失值
+SELECT id, 
+       CASE 
+           WHEN sale_date IS NULL THEN '2025-01-01'
+           ELSE sale_date
+       END AS sale_date,
+       customer_id, 
+       product_id, 
+       quantity, 
+       price, 
+       total_amount, 
+       region 
+FROM sales_data;
+
+```
+
+## 移除特殊字符
+
+### 说明
+
+特殊字符会影响数据的分析，可以使用 `REGEXP_REPLACE` 函数来移除这些字符。在实际项目中，移除特殊字符常用于清理文本字段中的噪声字符，使数据更加整洁和规范。
+
+### 实现
+
+```sql
+-- 移除特殊字符
+SELECT id, sale_date, customer_id, 
+       REGEXP_REPLACE(product_id, '[^a-zA-Z0-9]', '') AS cleaned_product_id,
+       quantity, 
+       price, 
+       total_amount, 
+       region
+FROM sales_data;
+```
+
+## 转换数据类型
+
+### 说明
+
+有时候需要将数据从一种类型转换为另一种类型，例如将字符串转换为日期类型。数据类型的转换能够保证数据的一致性和准确性。在实际项目中，常用于标准化数据格式，如日期、金额等。
+
+### 实现
+
+```sql
+-- 将字符串转换为日期
+SELECT id, CAST(sale_date AS DATE) AS sale_date, 
+    customer_id, product_id, quantity, 
+    CAST(price AS DECIMAL(10, 2)) AS price, 
+    CAST(total_amount AS DECIMAL(10, 2)) AS total_amount, region 
+FROM sales_data;
+```
+
+## 删除空格
+
+### 说明
+
+在数据清洗过程中，字符串前后的空格会导致数据分析结果不准确。我们可以使用 `TRIM` 函数删除空格。在实际项目中，删除空格常用于清理包含多余空格的文本字段。
+
+### 实现
+
+```sql
+-- 删除空白值
+SELECT id, 
+       TRIM(sale_date) AS sale_date, 
+       customer_id, 
+       product_id, 
+       quantity, 
+       price, 
+       total_amount, 
+       TRIM(region) AS region
+FROM sales_data;
+```
+
+## 转换大小写
+
+### 说明
+
+为了统一数据格式，可以将文本字段转换为小写或大写。在实际项目中，转换大小写常用于确保数据的一致性，例如在客户名称、产品名称等字段中。
+
+### 实现
+
+```sql
+-- 将区域字段转换为小写
+SELECT id, 
+       sale_date, 
+       customer_id, 
+       product_id, 
+       quantity, 
+       price, 
+       total_amount, 
+       LOWER(region) AS region
+FROM sales_data;
+```
+
+## 删除异常值
+
+### 说明
+
+异常值可能会影响数据分析的结果，使用 `DELETE` 语句可以删除这些记录。在实际项目中，删除异常值常用于剔除极端或错误的数据，以保证分析结果的准确性。
+
+### 实现
+
+< -5000;
+```
+
+## 去重
+
+### 说明
+
+在数据集中，重复记录会影响数据分析的准确性。我们可以使用 `DISTINCT` 或者 `ROW_NUMBER()` 函数来去除重复记录。在实际项目中，去重操作常用于合并多个数据源或清理历史数据时。
+
+### 实现
+
+```sql
+-- 使用 DISTINCT 去重
+SELECT DISTINCT customer_id, product_id, region FROM sales_data;
+
+-- 使用 ROW_NUMBER() 去重
+WITH RowNumCTE AS (
+    SELECT *,
+           ROW_NUMBER() OVER(PARTITION BY customer_id, product_id, region ORDER BY id) AS row_num
+    FROM sales_data
+)
+SELECT id, sale_date, customer_id, product_id, quantity, price, total_amount, region
+FROM RowNumCTE
+WHERE row_num = 1;
+```
+
+## 数据分组和聚合
+
+### 说明
+
+通过分组和聚合，可以生成汇总报告，了解数据的整体情况。分组和聚合操作可以帮助我们发现数据中的模式和趋势。在实际项目中，常用于统计、分析数据，如计算销售总额、平均值等。
+
+### 实现
+
+```sql
+-- 按区域分组计算总销售额
+SELECT region, SUM(total_amount) AS total_sales FROM sales_data GROUP BY region;
+
+-- 按产品分组计算总销售量
+SELECT product_id, SUM(quantity) AS total_quantity FROM sales_data GROUP BY product_id;
+```
+
+## 数据筛选
+
+### 说明
+
+使用 `WHERE` 子句筛选出符合特定条件的数据。在实际项目中，数据筛选常用于提取感兴趣的数据子集，如筛选出高价值客户、特定时间段的销售数据等。
+
+### 实现
+
+```sql
+-- 筛选出销售金额大于500的记录
+SELECT * FROM sales_data WHERE total_amount >
+
+## 数据排序
+
+### 说明
+
+排序可以帮助我们按特定顺序查看数据，发现数据中的模式和趋势。在实际项目中，排序常用于数据展示、报告生成等场景。
+
+### 实现
+
+```sql
+-- 按销售金额排序
+SELECT * FROM sales_data ORDER BY total_amount DESC;
+```
+
+## 合并列数据
+
+### 说明
+
+在某些情况下，我们需要将多个列的数据合并为一列。在实际项目中，合并列数据常用于生成综合信息字段，例如完整的地址、姓名等。
+
+### 实现
+
+```sql
+-- 合并产品ID和区域字段
+SELECT id,       sale_date,       customer_id,       product_id || '-' || region AS combined_field,       quantity,       price,       total_amountFROM sales_data;
+```
+
+## 合并数据
+
+### 说明
+
+使用 `UNION` 操作将多个结果集合并在一起，形成一个完整的结果集。在实际项目中，合并数据常用于将多个查询结果整合在一起，形成统一的分析数据集。
+
+### 实现
+
+```sql
+-- 合并两个结果集
+SELECT id, sale_date, customer_id, product_id, quantity, price, total_amount, region FROM sales_data
+UNION
+SELECT id, sale_date, customer_id, product_id, quantity, price, total_amount, region FROM another_sales_data;
+```
+
+通过以上的SQL数据清洗和预处理技术，您可以有效地处理和转换数据，为后续的数据分析和挖掘奠定坚实的基础。数据清洗不仅能提高数据质量，还能提升数据分析的准确性和可靠性。

+# Lakehouse Data Share 跨账号数据共享入门指导
+
+## 1. 方案概述
+
+### 1.1 什么是Data Share
+
+Data Share是Lakehouse提供的**无复制数据共享功能**，可在同一服务区域内实现**跨账户或跨服务实例**的数据授权与使用。与传统的数据复制或导入方案不同，Data Share不需要在企业间手动搭建数据同步链路，而是通过"授权"方式直接提供对源数据的只读访问，且实时更新。
+
+### 1.2 核心优势
+
+* **无复制、低延迟**：无需在企业间重复存储或定期同步，数据变更可以实时传播给消费方
+* **安全可控**：数据仅以"只读"形式分享，且随时可通过权限管控移除共享对象
+* **易于扩展**：通过View可以灵活过滤数据列或行，实现精细化的分享控制
+* **降低成本**：消费方无需为被分享的数据存储付费，仅需使用自己的计算资源处理数据
+
+### 1.3 适用场景
+
+* **实时共享场景**：企业A将交易日志、用户行为数据等实时共享给企业B，企业B无需数据同步即可实时查询
+* **多方协作分析**：多家合作方基于同一份实时数据进行分析，减少重复存储和传输成本
+* **数据提供商与消费者模式**：数据提供方将部分数据开放给合作伙伴，消费方无需承担存储成本即可获得只读数据
+
+## 2. 工作原理
+
+Data Share的核心工作原理是：
+
+1. **数据保留在提供方**：数据始终存储在数据提供方的账户中
+2. **共享元数据**：共享元数据和访问权限给消费方
+3. **访问控制**：消费方通过受控的只读访问权限查询数据
+4. **实时更新**：提供方的数据更新后，消费方立即能访问到最新数据
+
+**数据共享流程**：
+
+:-: ![](.topwrite/assets/image_1747735731291.png =322)
+
+数据提供方保留完全的控制权，可以随时更新或移除共享数据。当源数据更新时，消费方可立即获取最新数据，无需额外的数据同步操作。
+
+## 3. 使用前提条件
+
+* 数据提供方和数据消费方均需有Lakehouse实例
+* 双方需在同一服务区域内
+* 数据提供方需具备"实例管理员"(instance\_admin)角色权限
+* 数据共享操作需要消费方提供其服务实例名称
+
+## 4. 实操指南：数据提供方
+
+### 4.1 创建分享对象
+
+数据提供方（数据所有者）需要执行以下步骤创建并配置分享对象：
+
+#### 4.1.1 SQL方式
+
+```sql
+-- 步骤1：创建Share对象
+CREATE SHARE taxi_data_share;
+
+-- 步骤2：将表添加到Share对象中
+GRANT SELECT, READ METADATA ON TABLE demo_schema.taxi_zone_lookup TO SHARE taxi_data_share;
+
+-- 步骤3：指定接收实例
+ALTER SHARE taxi_data_share ADD INSTANCE target_instance_name;
+```
+
+#### 4.1.2 Web界面方式
+
+1. 使用具备"实例管理员"角色的账号登录Lakehouse控制台
+2. 左侧导航选择"数据管理" → "数据分享"，点击"+新增分享"
+3. 填写分享名称（如taxi\_data\_share），选择工作空间
+4. 点击"添加"选择要分享的数据对象（如taxi\_zone\_lookup表）
+5. 点击"接收实例"下的"添加"，输入消费方提供的服务实例名称
+6. 点击"确定"完成创建
+
+:-: ![](.topwrite/assets/image_1747742254855.png =699)
+
+#### 4.1.3 针对部分数据创建视图再共享
+
+如果只需要共享表的部分数据，可以先创建视图，然后共享视图：
+
+```sql
+-- 创建专用schema用于管理分享视图
+CREATE SCHEMA share_views;
+
+-- 创建筛选数据的视图
+CREATE VIEW share_views.filtered_taxi_zones AS 
+SELECT * FROM demo_schema.taxi_zone_lookup 
+WHERE borough = 'Manhattan';
+
+-- 共享视图
+GRANT SELECT, READ METADATA ON VIEW share_views.filtered_taxi_zones TO SHARE taxi_data_share;
+```
+
+### 4.2 验证分享配置
+
+创建并配置完成后，可以通过以下命令验证分享是否正确配置：
+
+```sql
+-- 查看所有Share对象
+SHOW SHARES;
+
+-- 查看特定Share的详细信息
+DESC SHARE taxi_data_share;
+```
+
+示例输出：
+
+```
+share_name       provider     provider_instance    provider_workspace  scope    to_instance        kind
+---------------------------------------------------------------------------------------------
+taxi_data_share  provider_instance_name  source_instance_name   source_workspace    PRIVATE  target_instance_name OUTBOUND
+```
+
+## 5. 实操指南：数据消费方
+
+数据消费方（接收方）需要执行以下步骤来访问共享数据：
+
+### 5.1 查看可用共享
+
+#### 5.1.1 SQL方式
+
+```sql
+-- 查看所有可见的Share
+SHOW SHARES;
+```
+
+示例输出（从消费方实例查看）：
+
+```
+share_name       provider     provider_instance    provider_workspace  scope    to_instance  kind
+---------------------------------------------------------------------------------
+taxi_data_share  provider_instance_name  source_instance_name   source_workspace    PRIVATE             INBOUND
+```
+
+```sql
+-- 查看Share对象中包含的数据对象
+DESC SHARE source_instance_name.taxi_data_share;
+```
+
+#### 5.1.2 Web界面方式
+
+1. 登录数据消费方的Lakehouse控制台
+2. 左侧导航选择"数据管理" → "数据分享"
+3. 切换到"分享给我"页签，即可看到所有接收到的分享
+
+:-: ![](.topwrite/assets/image_1747742432405.png =757)
+
+### 5.2 创建本地Schema关联共享数据
+
+#### 5.2.1 SQL方式
+
+```sql
+-- 创建本地Schema映射到共享数据
+CREATE SCHEMA shared_taxi_data FROM SHARE source_instance_name.taxi_data_share.source_schema;
+```
+
+其中：
+
+* `shared_taxi_data`：在本地创建的schema名称（可自定义）
+* `source_instance_name`：提供方的实例名称
+* `taxi_data_share`：分享对象名称
+* `source_schema`：提供方的源schema名称
+
+#### 5.2.2 Web界面方式
+
+1. 在"分享给我"页签中找到目标分享对象
+2. 点击"提取"按钮
+3. 在弹窗中选择"源schema"，并指定在本地创建的schema名称
+4. 点击"确定"完成提取
+
+:-: ![](.topwrite/assets/image_1747742473685.png =373)
+
+### 5.3 使用共享数据
+
+创建schema后，共享数据将以只读方式出现在本地schema中：
+
+```sql
+-- 查询共享表数据
+SELECT * FROM shared_taxi_data.taxi_zone_lookup LIMIT 5;
+
+-- 创建分析视图
+CREATE VIEW my_analysis AS
+SELECT borough, COUNT(*) as zone_count
+FROM shared_taxi_data.taxi_zone_lookup
+GROUP BY borough;
+
+-- 与本地数据关联分析
+SELECT t.*, z.borough, z.zone
+FROM my_local_table t
+JOIN shared_taxi_data.taxi_zone_lookup z ON t.location_id = z.locationid;
+```
+
+## 6. 完整案例：跨账号共享出租车区域数据
+
+### 6.1 背景场景
+
+A公司运营纽约市出租车服务并维护`taxi_zone_lookup`表，包含所有区域信息。B公司是一家分析公司，需要访问这些区域数据进行分析，但不需要复制数据。
+
+### 6.2 实施步骤
+
+#### 6.2.1 查看源表数据
+
+首先，A公司查看要共享的表结构：
+
+```sql
+DESC TABLE EXTENDED demo_schema.taxi_zone_lookup;
+```
+
+结果显示表结构如下：
+
+```
+column_name  data_type  comment
+----------------------------------
+locationid   bigint     PULocationID or DOLocationID
+borough      string     
+zone         string     
+service_zone string     
+```
+
+表中包含265行数据，记录了纽约市出租车区域信息。
+
+#### 6.2.2 创建分享对象
+
+A公司创建分享对象并配置：
+
+```sql
+-- 创建Share对象
+CREATE SHARE taxi_data_share;
+
+-- 添加表到Share
+GRANT SELECT, READ METADATA ON TABLE demo_schema.taxi_zone_lookup TO SHARE taxi_data_share;
+
+-- 指定B公司的实例作为接收方
+ALTER SHARE taxi_data_share ADD INSTANCE target_instance_name;
+```
+
+#### 6.2.3 验证分享配置
+
+A公司验证分享配置是否正确：
+
+```sql
+DESC SHARE taxi_data_share;
+```
+
+输出结果显示：
+
+```
+kind      name                                shared_on
+-------------------------------------------------------
+WORKSPACE <WS>                                2025-05-15 20:37:58.13
+SCHEMA    <WS>.demo_schema                    2025-05-15 20:38:02.018
+TABLE     <WS>.demo_schema.taxi_zone_lookup   2025-05-15 20:38:02.018
+```
+
+```sql
+SHOW SHARES;
+```
+
+输出结果包含新创建的分享：
+
+```
+share_name       provider     provider_instance    provider_workspace  scope    to_instance        kind
+--------------------------------------------------------------------------------------
+taxi_data_share  provider_instance_name  source_instance_name   source_workspace    PRIVATE  target_instance_name OUTBOUND
+```
+
+#### 6.2.4 B公司访问共享数据
+
+B公司（实例target\_instance\_name）执行以下操作使用共享数据：
+
+```sql
+-- 查看可用分享
+SHOW SHARES;
+
+-- 查看分享内容
+DESC SHARE source_instance_name.taxi_data_share;
+
+-- 创建本地Schema
+CREATE SCHEMA taxi_data FROM SHARE source_instance_name.taxi_data_share.demo_schema;
+
+-- 查询数据
+SELECT borough, COUNT(*) as zone_count 
+FROM taxi_data.taxi_zone_lookup 
+GROUP BY borough 
+ORDER BY zone_count DESC;
+```
+
+B公司可以查询结果并创建报表，无需复制数据。当A公司更新原表数据时，B公司会立即看到最新数据。
+
+## 7. 最佳实践
+
+### 7.1 安全性最佳实践
+
+* **使用视图限制敏感数据**：通过视图筛选行或列，确保只共享必要数据
+* **定期审计共享对象**：使用`SHOW SHARES`和`DESC SHARE`命令定期检查共享内容
+* **最小权限原则**：只授予必要的权限（SELECT和READ METADATA）
+* **不要分享凭证**：严禁共享管理员账号，使用Data Share进行安全的数据共享
+
+### 7.2 性能与成本优化
+
+* **使用筛选视图**：通过视图限制数据量，提高查询性能
+* **注意时区设置**：确保提供方和消费方使用相同的时区设置，避免时间相关查询问题
+
+## 8. 常见问题与故障排除
+
+### 问题1：无法看到共享数据
+
+**可能原因**：
+* 权限配置错误，例如未授予 `READ METADATA` 权限。
+* 实例名称输入有误。
+
+**解决方法**：
+* 提供方使用 `SHOW GRANTS TO SHARE` 命令，检查 share 中共享的对象是否同时被授予了 `SELECT` 和 `READ METADATA` 权限。
+* 验证实例名称是否正确。
+
+### 问题2：无法查询共享数据
+
+**可能原因**：
+* 缺少SELECT权限
+
+**解决方法**：
+
+```sql
+GRANT SELECT ON TABLE <table_name> TO SHARE <share_name>;
+```

+# 数据可视化
+
+本文介绍如何使用云器产品中的图表将 SQL 工作表结果可视化。图表可将查询结果可视化，传达逻辑关系，并帮助您做出更明智的决策。图表可让您快速了解数据中的模式并识别其中的异常值。
+
+当前支持的图表类型有：
+
+* 折线图
+* 柱形图
+
+## 创建图表
+
+在开发中运行查询时，可以根据结果显示图表。
+
+1. 点击开发或工作区，新建/选择一个SQL任务
+2. 执行Select查询任务
+3. 在查询结果的数据tab下，点击「图表」。
+
+## 修改图表
+
+如果您点击「图表」来可视化工作表结果，首先需要基于图表类型，筛选出必选的字段后，可视化区域才会出现相应的图表。
+
+鼠标悬浮在图表上，可查看每个数据点的详细信息。例如，您可以折线图形式查看结果：
+
+![](.topwrite/assets/image_1742200992399.png =757)
+
+^
+
+在可视化右侧区域的「设置」下，筛选需要呈现的信息：
+
+1.图标类型：折线图、柱形图
+
+2.X轴字段：可视化呈现的数值在趋势图上的呈现趋势。
+
+注意：当前不支持按照X轴所选的字段进行聚合。
+
+3.Y轴字段：
+
+![](.topwrite/assets/image_1742201014009.png =347)
+
+Y轴支持使用聚合函数从多个数据点中确定单个值。这些统计方式对应的函数如下：
+
+* 总计：sum
+* 计数：count
+* 均值：average
+* 最大值：maximum
+* 最小值：minimum
+
+4\. 添加Y轴、或分组
+
+最多支持添加10个Y轴的字段放在同一个表格上进行分析；
+
+添加分组即是将已添加到Y轴的字段进行一个group by的操作。
+
+注：当只有一个Y轴时，才允许选择分组字段，同时分组字段只允许选择一个。
+
+## 已知局限
+
+若X轴数值过多时，若需要看到某个趋势上的一个具体数值，建议将图表上的范围缩短后才可以查看到准确的数据点。
+
+例如下图：当鼠标悬浮在可视化图表上，呈现出具体的时间戳信息时，才是准确的数值。
+
+![](.topwrite/assets/image_1742201080540.png =387)
+
+^
+
+## 使用案例
+
+基于时间的趋势图
+
+场景一：如果要保留时间跨度的差异，结果数据类型需要是时间类型，如下：
+
+* order\_date是一个时间戳类型，趋势图会自动按时间间隔实际情况展现数据，这样更能准确体现“趋势”
+
+```
+select order_date, count(*) as c from big_data_table group by order_date;
+```
+
+![](.topwrite/assets/20250317-190632.jpeg =617)
+
+^
+
+![](.topwrite/assets/20250317-190714.jpeg =607)
+
+^
+
+![](.topwrite/assets/20250317-190759.jpeg =608)
+
+^
+
+场景二：如果要**忽略**时间跨度的差异，只保留具体结果点位，结果数据类型转换为string即可（order\_date::string），如下
+
+```
+select order_date::string, count(*) as c from big_data_table group by order_date;
+```
+
+![](.topwrite/assets/20250317-190854.jpeg =654)

+
+## 环境配置
+
+### **重要说明：配置必须严格按照以下顺序执行**
+
+```
+配置依赖关系和顺序：
+1. Account级别：Service Principal创建和配置
+2. Account级别：Unity Catalog Metastore External Data Access启用
+3. Account级别：Storage Credential和External Location配置
+4. Workspace级别：Catalog和Schema创建
+5. Workspace级别：Service Principal权限配置
+6. 端到端测试和验证
+```
+
+### 1. Databricks 关键配置
+
+#### 1.1 Service Principal创建和配置
+
+**步骤1：创建Service Principal（Account Console操作）**
+
+1. 登录 **Databricks Account Console**（注意：不是workspace）
+2. 导航路径：`Account settings` → `User management` → `Service principals`
+3. 点击 `Add service principal`
+4. 填写配置：
+   * **Display name**: `Lakehouse-Integration-SP`
+   * **Application ID**: 自动生成（**重要：记录此CLIENT\_ID**）
+5. 点击 `Add` 创建
+
+**步骤2：生成 Secret（Account Console 操作）**
+
+1. 进入创建的 Service Principal 详情页
+2. 点击 `Secrets` tab
+3. 点击 `Generate secret`
+4. **重要**：立即复制并安全保存 Secret 值（只显示一次）
+5. 记录以下信息用于云器连接：
+   ```
+   CLIENT_ID
+   CLIENT_SECRET
+   ```
+
+**步骤3：分配 workspace 权限（Account Console 操作）**
+
+1. 在Account Console中，导航到 `Workspaces`
+2. 选择目标workspace
+3. 点击 `Permissions` tab
+4. 点击 `Add permissions`
+5. 搜索并选择创建的 Service Principal
+6. 分配权限：`Admin`（推荐用于初始配置，后续可调整为User）
+
+#### 1.2 Unity Catalog Metastore 配置
+
+**步骤1：检查Metastore状态（Workspace SQL编辑器）**
+
+```sql
+-- 在Databricks workspace中执行
+DESCRIBE METASTORE;
+
+-- 检查输出中的关键信息：
+-- Metastore Name: metastore名称
+-- Cloud: 应该是 'aws'
+-- Region: 应该与云器相同
+-- Privileged Model Version: 应该是 '1.0' 或更高
+```
+
+**步骤2：启用External Data Access（Account Console操作）**
+
+1. 在 Databricks 工作区左侧的主导航栏中，点击 `Catalog\` 选项进入 Catalog Explorer。
+2. 在 Catalog Explorer 的主界面上方，点击齿轮形状的设置图标 (Manage)。
+3. 在弹出的下拉菜单中，点击 `Metastore\` 选项。
+4. 在 Metastore 页面确保以下选项已启用：
+   ```
+   ✅ External data access: Enabled
+   ```
+
+**步骤3：Service Principal 权限配置**
+
+1. 进入 Databricks Workspace Console。
+
+* 在左侧边栏中，点击 `Catalog` 进入 Catalog 浏览器。&#x20;
+* 在 Catalog 列表中，点击您希望授权的目标 Catalog，例如 `databricks_catalog`。&#x20;
+
+2\. 打开权限管理
+
+* 在所选 Catalog 的主页面中，点击 Permissions 标签页。&#x20;
+* 点击 Grant 按钮以打开授权对话框。&#x20;
+
+3\. 选择主体 (Principal)&#x20;
+
+* 在弹出的 Grant on <Catalog 名称> 对话框中，于 Principals 字段搜索并选择您的服务主体。
+
+4\. 分配权限
+
+* 使用权限预设 (Privilege presets)：为了简化配置，建议使用预设角色。对于需要读写和创建对象的场景，从下拉菜单中选择 Data Editor。此预设会自动授予一系列常用权限，如 `USE CATALOG, USE SCHEMA, SELECT, MODIFY, CREATE TABLE` 等。
+* 授予外部访问权限 (关键步骤)：如果您需要允许外部系统（非 Databricks）通过此服务主体访问数据，请务必勾选页面底部的` EXTERNAL USE SCHEMA` 权限。此权限是允许外部引擎访问此 Catalog 中 Schema 的关键。&#x20;
+
+5\. 确认授权：检查所选的权限配置无误后，点击 `Confirm` 按钮完成授权。
+
+### 2. 云器 Lakehouse 环境配置
+
+#### 2.1 环境准备检查
+
+**环境要求确认**：
+
+*   ✅ **必选**：AWS 环境的云器 Lakehouse
+*   ✅ **推荐**：与 Databricks 相同 AWS 区域部署
+
+#### 步骤1：建立Catalog连接
+
+```sql
+-- 在云器 Lakehouse 中执行
+CREATE CATALOG CONNECTION IF NOT EXISTS databricks_aws_conn
+TYPE DATABRICKS
+HOST = 'https://dbc-91642d78-eab3.cloud.databricks.com/'  -- Databricks 工作空间的URL
+CLIENT_ID = 'your-service-principal-id'
+CLIENT_SECRET = 'your-service-principal-secret'
+ACCESS_REGION = 'us-west-2'
+COMMENT = 'Databricks Unity Catalog 企业级连接';
+```
+
+#### 步骤2：创建External Catalog
+
+```sql
+-- 在云器 Lakehouse 中执行
+CREATE EXTERNAL CATALOG databricks_catalog 
+CONNECTION databricks_aws_conn 
+OPTIONS (
+    'catalog' = 'datagpt_catalog'  -- 目标的 Catalog 名称（不是 Metastore 名称）
+);
+```
+
+#### 步骤3：验证连通性
+
+```
+-- 展示 Catalog 中的 Databricks 的 Schema 信息
+SHOW SCHEMAS IN databricks_catalog;
+
+-- 展示 Databricks default Schema 下的表信息
+SHOW TABLES in databricks_catalog.default;
+
+-- 查询从 Databricks 表的数据
+SELECT * FROM databricks_catalog.<databricks_schema>.<databricks_table> LIMIT 100;
+
+```
+
+^
+
+## 完整实施代码
+
+### Databricks 端：企业级表设计
+
+#### 1. 核心业务表创建
+
+```sql
+-- ==== Databricks端实施 ====

+
+#### ✅ Workspace 级别配置
+
+* [ ] 专用 Catalog 已创建（enterprise_catalog）
+* [ ] 专用 Schema 已创建（core_data）
+* [ ] Service Principal已获得必要权限：
+
+#### ✅ 表级别配置

+
+## 问题排查指南
+
+### 1. 表访问权限问题
+
+#### 场景：EXTERNAL USE SCHEMA权限缺失
+
+```
+错误信息：Access denied for external schema access
+```
+
+**排查步骤**：
+
+```sql
+-- Databricks端 - 检查权限配置
+SHOW GRANTS TO SERVICE_PRINCIPAL 'your-application-id';
+
+-- 查看是否有EXTERNAL USE权限
+SELECT 
+    grantee,
+    privilege_type,
+    object_type
+FROM system.information_schema.grants 
+WHERE grantee = 'your-application-id'
+AND privilege_type = 'EXTERNAL_USE';
+```
+
+**解决方案**：
+
+```sql
+-- 重新配置EXTERNAL USE SCHEMA权限
+GRANT EXTERNAL USE SCHEMA ON SCHEMA enterprise_catalog.core_data 
+TO SERVICE_PRINCIPAL 'your-application-id';
+```
+
+#### 场景：外部表访问失败
+
+```
+错误信息：TABLE_DB_STORAGE cannot be accessed externally
+```
+
+**根本原因分析**：
+
+* 表创建时未指定外部存储位置
+* 即使使用`USING DELTA`，缺少`LOCATION`子句会创建内部存储表
+
+**企业级解决方案**：
+
+```sql
+-- 在Databricks中重新设计表架构
+CREATE TABLE enterprise_catalog.core_data.table_name_v2 (
+    -- 列定义
+    column1 INT,
+    column2 STRING
+) 
+USING DELTA 
+LOCATION 's3://enterprise-data-lake/core/table_name_v2/';
+
+-- 数据迁移策略
+INSERT INTO enterprise_catalog.core_data.table_name_v2 
+SELECT * FROM enterprise_catalog.core_data.table_name_v1;
+
+-- 验证表类型
+SHOW TABLE EXTENDED enterprise_catalog.core_data.table_name_v2;
+```
+
+### 2. 连接配置问题
+
+#### 场景：Service Principal认证失败
+
+```
+错误信息：Authentication failed for service principal
+```
+
+**企业级排查清单**：
+
+* [ ] 确认 CLIENT_ID 和 CLIENT_SECRET 正确
+* [ ] 验证Service Principal在Account Console中存在
+* [ ] 检查Service Principal的workspace权限
+* [ ] 确认Unity Catalog External Data Access已启用
+
+**解决步骤**：
+
+```sql
+-- 1. 在Databricks中验证Service Principal
+SELECT current_user() as current_principal;
+
+-- 2. 检查workspace访问权限（在Account Console中操作）
+
+-- 3. 重新生成Secret（如需要）
+-- 在Account Console → Service Principal → Secrets → Generate secret
+
+-- 4. 在云器中更新连接信息
+ALTER CONNECTION databricks_aws_conn 
+SET CLIENT_SECRET = 'new-secret-value';
+```
+
+### 3. 存储访问问题
+
+#### 场景：S3存储位置无法访问
+
+```
+错误信息：Access denied to S3 location
+```
+
+**排查步骤**：
+
+```sql
+-- Databricks端测试存储访问
+LIST 's3://your-bucket/external-tables/';
+
+-- 检查Storage Credential配置
+DESCRIBE STORAGE CREDENTIAL enterprise_s3_credential;
+
+-- 检查External Location配置
+DESCRIBE EXTERNAL LOCATION enterprise_external_tables;
+```
+
+**解决方案**：
+
+```json
+// 检查IAM Role Policy配置
+{
+    "Version": "2012-10-17",
+    "Statement": [
+        {
+            "Effect": "Allow",
+            "Action": [
+                "s3:GetObject",
+                "s3:PutObject",
+                "s3:DeleteObject",
+                "s3:ListBucket",
+                "s3:GetBucketLocation"
+            ],
+            "Resource": [
+                "arn:aws:s3:::your-bucket",
+                "arn:aws:s3:::your-bucket/*"
+            ]
+        }
+    ]
+}
+```
+
+## 企业级部署总结
+
+### ✅ 核心能力确认
+
+1. **跨平台数据访问**：外部表实现无缝数据共享
+2. **企业级查询能力**：复杂分析、JOIN、聚合全面支持
+3. **权限管理**：基于Unity Catalog的细粒度权限控制

+# 如何让 DataGPT 回答得更准确
+
+作为一个基于数据的问答系统，回答的准确性尤为重要。系统提供以下手段来保障准确性：
+
+## 1.数据治理
+
+* **数据画像**（DataGPT Profile）：系统提供数据画像功能，让您了解底层数据集表的数据状态。通过 **左侧导航栏 -> 数据 -> 数据表**，在表详情页的 **统计分析** 页签，可以查看数据状态，帮助您进行数据治理。建立数据画像，也有助于通过自然语言找到合适的目标数据。
+
+> 注意：DataGPT 仅提供数据的 **统计分析** 功能，供客户查看数据分布、进行统计分析。数据质量由上游数据平台保证。
+
+* **表、列描述与列别名配置**：为表和列添加准确的描述和别名信息，这有助于系统精确地将问题与数据做匹配。在 **左侧导航栏 -> 数据 -> 数据表** 中，可以分别配置表级别的描述、列的别名（Alias）和列的描述（Description）。数据表和列有清晰准确的别名和描述，不同表和列在名称和描述上的歧义越小，回答的准确度越高。
+
+* **列类型与用途**：请根据列的实际含义填写列类型（ColumnType）与用途（Intended For）。**该选项会影响系统是否选择该列作为数据来源**。
+
+## 2. 划分分析域
+
+拆分业务域（或分析域）有助于系统更加聚焦于特定数据。
+
+1. 预先划分分析域，减少每个 Domain 里涉及的数据表范围和知识范围。
+2. 针对域（Domain）提问更为聚焦，同时域会绑定用户，能做到表级别的数据隔离。
+
+## 3. 创建指标与答案构建器
+
+指标是聚合函数或基于聚合函数的计算结果，答案构建器是基于 SQL 的模板定义，两者均为预定义对象。基于指标和答案构建器进行回答，会使准确率大幅提升。如果对问答准确率有严格要求，建议预先定义好它们。指标支持别名，用于匹配更多的表达方式。请参考[指标与答案构建器](metrics_answer_build.md)
+
+:-: ![](.topwrite/assets/image_1736900144814.png =636)
+
+## 4. 采用输入提示
+
+**列值智能匹配**：启用列值索引功能后，系统将在您输入时提供实时数据值提示，以确保查询结果的准确性与相关性。

+# 数据湖常见问题 FAQ
+
+#### **问题1**：**用 PUT 命令上传文件到 Volume 路径之后，在 SQL 处理时，查询不到文件**
+
+**解答**：如果创建 Volume 对象时开启了文件目录表( `DIRECTORY = (enable = TRUE` ) ， 则在向该 Volume 路径中添加新文件之后，需要手动同步该变化到 Lakehouse 元数据系统，可以使用命令 `alter volume xxxx refresh; `（该命令需要执行者拥有对该 volume 对象有 alter 权限：`GRANT ALTER ON VOLUME xxxx  TO USER datalake_user;`）
+
+^
+
+#### **问题2**：**查询数据湖 Volume 中文件时，是否支持 CSV 文件为压缩格式**
+
+**解答**：当前版本暂不支持 CSV 压缩格式文件，会在后续版本中支持。
+
+^
+
+#### **问题3：查询 CSV 文件时报错**：**CZLH-00000:CZLH-71001: CZ_SQL_TIMEZONE should exist in context**；
+
+**解答**：需在查询中指定默认时区：在查询 volume 的 select 语句的options 中，添加 `'timeZone' = 'Asia/Shanghai' `的选项，例如：
+
+```
+select * from volume hz_csv_volume (
+  order_id STRING,
+  order_item_id INT,
+  product_id STRING,
+  seller_id STRING,
+  shipping_limit_date TIMESTAMP,
+  price DECIMAL(10,2),
+  freight_value DECIMAL(10,2)
+)using csv 
+ options(
+    'header'='true',
+    'sep'=',',
+    'timeZone' = 'Asia/Shanghai'
+ ) files('brazil-ecommerce/olist_order_items_dataset.csv');
+```
+
+^
+
+#### **问题4**：**执行远程函数（remote function）时报错**：**CZLH-42000:\[1,8] Semantic analysis exception - function not found**
+
+**解答**：可能原因：
+
+1. 函数是schema 级别对象，请保证执行函数时携带了正确的 schema 信息，如：函数 fc\_orc\_schema 是属于 public schema 下的对象，引用时需携带 schema 信息：`public.fc_orc_schema()`
+2. 目前执行remote function时，需要在 SQL 语句前携带  `set cz.sql.remote.udf.enabled=true; `并一起执行
+
+```
+set cz.sql.remote.udf.enabled = true;
+SELECT public.fc_orc_schema('orc','<url>') as schema_orc;
+```
+
+####
+
+#### **问题5：执行远程函数时报错**：**CZLH-XX000: failed to hook preExecute: urllib3 v2.0 only supports OpenSSL 1.1.1+, currently the 'ssl' module is compiled with 'OpenSSL 1.1.0l 10 Sep 2019'.**
+
+**解答**：python 代码中需要处理文件url 链接时，需要 urllib3 的库版本与 OpenSSL 版本不兼容，可以安装 urllib3 d的1.26.9 版本代替：`pip3 install --upgrade urllib3==1.26.9 -t .`

+# 数据湖分析
+
+## 概述
+
+云器 Lakehouse 作为一款湖仓一体化的数据平台，可以无缝连接云上对象存储（目前支持的云对象存储产品有：阿里云 OSS、腾讯云 COS、谷歌云 GCS、AWS S3），并利用自身一体化的数据处理引擎，结合业界领先的 AI 能力，高效处理数据湖中的半结构化和非结构化数据。在此过程中，平台采用统一的权限管理方法，确保数据安全与合规性。具体能力包括：
+
+1.  **感知、获取外部数据的能力**：随着数据量的不断增长，半结构化和非结构化数据在数据中所占比例越来越大，其重要性也日益凸显。
+2.  **便捷利用前沿 AI 技术的能力**：深度学习模型和大语言模型（LLM）的多模态能力，极大地降低了从业人员分析半结构化和非结构化数据的门槛。让数据平台便捷地利用这些能力，将数据分析范围从二维表格数据扩展到几乎所有数据（All Data），是分析能力维度的重要提升。
+3.  **对数据和文件统一管理和治理的能力**：将数据仓库中成熟、完善且通用的权限体系应用到数据和文件（如 AI 模型文件）上，例如：管控特定用户使用指定的模型文件，处理有权限的数据。同时，能够在组织视角对数据实现全局视图。
+
+以下是具体产品功能的详细介绍：
+
+1. [数据湖Volume对象](datalake_volume.md)：通过整合数据平台与非结构化数据，解决数据平台访问非结构化数据、AI/BI数据割裂的问题。例如，用户可以通过 Volume 对象轻松地将图片、文本等非结构化数据导入数据平台，进行进一步的分析和处理。
+2. [远程函数（Remote Function）](RemoteFunctionBestPractice.md)：为用户提供低门槛调用AI模型、大语言模型（LLM）分析数据的方法。例如，用户可以通过 Remote Function 轻松地调用预训练的深度学习模型，对图片进行分类、识别等任务。
+3. [统一湖仓元数据系统](datalake_privilege.md)：将结构化和非结构化数据整合于统一的 Catalog-Schema 视图，解决统一的湖仓元数据管理和权限管理问题，简化了数据的整理和访问。例如，管理员可以通过元数据系统为不同部门的员工分配相应的数据访问权限，确保数据安全和合规性。

+# 数据湖权限管理
+
+数据湖权限管理是确保数据安全和合规性的重要组成部分。通过合理的权限管理，您可以确保用户只能访问和操作其所需的数据和资源。数据湖的权限管理主要涉及两个方面：数据访问权限和函数调用权限。具体包括以下几个方面：
+
+1. Volume 对象的权限点与管理
+2. Remote Function 对象的权限点与管理
+
+## Volume 对象权限
+
+对于 Volume 对象，您可以设置以下权限：
+
+* 对象所属 Schema 的权限：CREATE / DROP
+* 对象本身的权限：READ / WRITE / ALTER
+
+### 示例 1：授权新用户访问 Volume
+
+假设您有一个名为 `datalake_user` 的新用户，您希望授权其访问 workspace 空间。首先，授予该用户 workspace_user 角色（该角色具有只读权限）：
+
+```
+GRANT ROLE workspace_user TO USER datalake_user;
+```
+
+接下来，如果您希望允许 `datalake_user` 用户对 Volume 对象进行读取、上传数据以及将文件元数据同步到 Lakehouse 元数据服务，需要进行以下授权：
+
+1. 授权使用计算资源 Virtual Cluster。
+2. 授予用户 `datalake_user` 对 Volume 的 READ、WRITE、ALTER 权限。
+
+具体步骤如下：
+
+```SQL
+GRANT USE VCLUSTER ON VCLUSTER DEFAULT TO USER datalake_user;
+```
+
+```SQL
+GRANT READ ON volume xxx TO USER datalake_user;
+GRANT WRITE ON volume xxx TO USER datalake_user;
+GRANT ALTER ON volume xxx TO USER datalake_user;
+```
+
+## Remote Function 对象权限
+
+对于 Remote Function 对象，您可以设置以下权限：
+
+* 对象所属 Schema 的权限：CREATE / DROP
+* 对象本身的权限：USE
+
+### 示例 2：授权用户使用 Remote Function
+
+假设您希望授权用户 `datalake_user` 使用名为 fc_image_2_text 的 Remote Function，您可以执行以下命令：
+
+```SQL
+GRANT USE ON FUNCTION fc_image_2_text TO USER datalake_user;
+```

+# 数据湖查询
+
+在创建 Volume 对象之后，您可以通过该对象直接查询外部存储路径中的 CSV、Parquet 和 ORC 格式的数据文件，无需依赖任何元数据系统。
+
+## 前提条件
+
+1. 如果数据在云厂商的对象存储中，请先完成创建 Storage Connection 和 External Volume 对象。
+2. 在 Lakehouse 中查询 Volume 中的文件前，请确认是否具备对目标 Volume 对象的读权限（READ）。如果同时需要使用 [PUT 命令](PUT.md) 上传文件，则需要具备读、写权限。可以使用 `show grants to user <user_name>` 查看当前用户是否具备上述权限。
+
+## 使用限制
+
+* 支持的外部存储包括：阿里云 OSS、腾讯云 COS 和 AWS S3。
+* 仅支持查询 CSV、Parquet 和 ORC 三种文件格式。
+* 仅支持 gzip、zstd 和 zlib 三种压缩格式。

+# 数据湖存储管理：Volume
+
+## 概述
+
+Lakehouse Volume 是在云器 Lakehouse 中表示云对象存储位置的对象。它提供了对云上对象存储的访问、存储、管理和组织文件等功能，可用于存储和访问各种格式的文件，包括结构化、半结构化和非结构化数据。它可以与表、视图等对象一样在Lakehouse 的 Schema 下进行组织和管理。使用 Volume 功能会带来如下收益：
+
+* 统一数据分析：支持在云器 Lakehouse 中调用 AI 负载处理对象存储中的图片、PDF 以及特殊格式的非结构化数据，与平台中的结构化数据做统一处理和分析
+* 统一权限管理：支持使用云器 Lakehouse 平台的权限系统，对库表以及对象存储中的文件做统一权限管理
+* 统一数据治理：对象存储中的数据会被云器 Lakehouse 平台统一管理和治理
+
+Lakehouse Volume按照数据存储位置分为 Internal Volume 和 External Volume 两种类型：
+
+| **特性** | **External Volume**                                                                                                                                    | **Internal Volume**                                                                                                                                                                                                                                                                                                                                   |

+# DataOps数据安全稳定生产实践
+
+## 概述
+
+DataOps 通过结合敏捷开发、数据管理和数据科学的最佳实践，能够显著提高数据管道的效率和质量。在 DataOps 整个数据研发运营流水线上，数据开发管理和数据运维是两个极为关键的环节。
+
+本实践围绕这两个环节展开，基于 NYC TLC Trip Record Data，构建 pipeline 进行数据清洗和指标统计分析，产出数据供 BI 查询使用。通过本实践，可了解到如下内容：
+
+* 如何便捷地构建定时调度运行的数据处理 pipeline，对数据同步、SQL 任务等进行统一的调度编排。
+* 如何利用监控告警规则，及时监控任务运行的稳定性。
+* 如何利用数据质量监控规则，监控数据产出的正确性，及时告警，防止问题数据扩散。
+* 如何利用完善的运维措施，来快速定位问题原因。
+* 如何提高监控告警的处置效率。
+
+## Pipeline
+
+整个 Pipeline 包含如下五个任务节点：
+
+* 1\_同步\_OSS：从OSS端，批量同步数据，写入到Lakehouse
+* 1\_同步\_Kafka：从Kafka端批量同步数据，写入到Lakehouse
+* 2\_数据清洗：对于源端同步进来的数据进行简单清洗加工、关联维度表进行拓宽
+* 3\_指标计算\_daily汇总：计算关键的业务指标
+* 6\_BI\_简单查询：使用SQL模拟BI查询的简单示意
+  ![](.topwrite/assets/image_1715856764265.png =414)
+
+## 主要步骤
+
+### 任务开发调度和提交发布运行
+
+使用 **任务开发** 模块的功能来编排整个 pipeline：首先进行数据同步导入，然后编写 SQL 代码进行数据清洗，按天维度统计出行数据、计算平均每单金额和平均乘客数等指标，最后供 BI 报表查询。
+
+#### 任务开发
+
+在任务开发界面，通过下图的新建按钮，可以按需创建同步任务、SQL 任务等任务类型：
+![](.topwrite/assets/image_1715856137643.png)
+
+^
+
+#### 任务调试运行
+
+任务创建后，可进行编码和配置。完成这些操作后，可使用“运行”功能测试代码逻辑是否正确。
+![](.topwrite/assets/image_1715856147701.png)
+
+^
+
+#### 任务调度配置和提交发布
+
+完成测试后，在“配置”选项中，可以设定任务的调度属性，包含定时调度的时间、调度的上游依赖等。配置完成后，通过点击“提交”按钮，将任务发布到生产环境进行定期调度运行。
+![](.topwrite/assets/image_1715856159293.png)
+
+### 配置监控告警以监控任务运行情况
+
+任务上线发布后，使用 **监控告警** 模块可配置监控规则，以监测任务运行失败等需要观测的状态或指标，并通过在告警中配置的通知渠道通知负责人进行处理。
+
+#### 监控规则配置
+
+以本次示例为例，配置监控任务实例的运行失败状态，给定具体的任务名称，并配置好通知渠道（基于通知策略）和通知人员等，如下图所示：
+![](.topwrite/assets/image_1715856178384.png)
+![](.topwrite/assets/image_1715856188374.png)
+
+在通知策略中，可配置推送间隔和次数，例如每 10 分钟发送一次，最多发送 6 次，以避免告警被遗漏。
+![](.topwrite/assets/image_1715856196213.png)
+
+### 使用数据质量监控数据产出的正确性
+
+除了监控任务调度运行状态外，为避免因上游数据变更或后续代码变更引入逻辑问题，也需要监控数据的正确性、合理性等，以确保业务方能够放心使用数据。这里会使用到 **数据质量** 模块的功能：
+
+#### 质量规则配置
+
+在 **数据质量** 模块，可以配置数据质量的监控规则，以监控任务产出表中的数据。
+![](.topwrite/assets/image_1715856220634.png)
+以 dws\_tripdata\_summary 表中的 avg\_passenger\_count（平均乘客数） 字段为例，监控其最大值要大于1（即平均至少有1个乘客），可以按照如下方式配置。
+![](.topwrite/assets/image_1715856226837.png)
+
+^
+
+#### 质量规则运行
+
+质量规则支持多种触发方式，例如手动触发、定时触发和周期任务触发。手动触发可用于测试规则配置的正确性。在本实例中，将质量规则配置为“周期任务触发”，即通过表的产出任务来触发，以达到在任务运行完成后即刻触发质量校验的目的，并配置为使用“强阻塞调度”模式。此方式意味着如果质量规则校验失败，则会将关联的调度任务实例状态也置为失败，从而阻塞下游任务实例的调度运行，防止数据问题扩散。
+![](.topwrite/assets/image_1715856234080.png)
+
+### 生产问题的运维处置
+
+1. 在任务调度运行后，通过监控检测到任务实例运行失败，收到 IM 告警
+   ![](.topwrite/assets/image_1715856242741.png =446)
+2. 基于监控告警的内容，可以直达告警对象
+   ![](.topwrite/assets/image_1715856478879.png)
+3. 排查任务实例失败的原因，从任务的变更记录中查找发现存在代码变动
+   ![](.topwrite/assets/image_1715856492223.png)
+4. 在运维中，点击“编辑”按钮，前往查看任务详情。在任务的版本中，可以查看到任务的提交历史记录。
+   ![](.topwrite/assets/image_1715856513403.png)
+5. 通过版本的对比功能查看具体的变动。定位到是代码逻辑改动引入的问题，进行代码回滚操作来修复，并重新提交。
+   ![](.topwrite/assets/image_1715856521466.png)
+6. 任务重新提交后，在实例的详情页进行运维处置，重跑任务实例，**注意选择使用最新的代码和配置**。
+   ![](.topwrite/assets/image_1715856529104.png)
+7. 实例重跑成功后，系统**会自动触发数据质量规则的重新运行**，校验通过。
+   ![](.topwrite/assets/image_1715856539792.png)
+8. 查看任务状态监控，实例状态通过重跑恢复成功后，**告警会自动关闭、不再推送，完全无需人工操作处置**。
+   ![](.topwrite/assets/image_1715856549114.png)
+
+## 小结
+
+通过 Lakehouse Studio 产品内置的数据开发、任务调度、任务运维、数据质量和监控告警功能的配合使用，在任务运行失败时，能第一时间告警通知责任人进行处置；通过操作审计定位变动、利用版本管理进行变更回滚、基于回滚后的代码重跑任务实例等，可快速进行处置；同时，监控告警事件与任务实例状态联动，重跑任务实例成功后，会自动关闭告警，无需手动操作，减少了告警处置环节，可大幅节约问题排查处置和数据生产恢复的时间。
+
+这些功能完整覆盖了 DataOps 中数据开发管理和数据运维两个关键环节的需求，能为“可测试、可监控、可回滚”的数据安全稳定生产提供坚实的落地保障。

+# 数据分享
+
+## 什么是数据分享
+
+数据分享是云器Lakehouse提供的无复制数据共享功能，用于同服务区域下跨账户或跨服务实例的数据授权使用。在云器Lakehouse中，用户可通过share对象，向同服务区域内的其他账户分享指定table或view的数据，而不需要实际将数据复制给其他账户。
+
+基于数据分享功能，账户间可便捷、安全地分享数据并与自身的数据进行关联计算，充分挖掘数据价值。
+
+通过share对象分享的数据通过权限管控的方式保障数据安全，数据提供方可随时通过对share的权限管控取消指定数据的分享。
+
+数据消费方无需对被分享的数据所占存储资源付费，但需要使用自身的计算资源处理被分享数据。当被分享数据发生变化时，数据消费方可以立即获得最新数据，无需进行数据同步。
+
+:-: ![](.topwrite/assets/image_1704779759719.png =752)
+
+## 典型应用场景
+
+A企业需要将自身数据提供给其客户B企业使用，需要能做到数据实时更新且避免建立高成本的数据实时同步链路。此时A企业可创建share对象，将需要提供的数据授权至share对象，并将share指定给B企业在云器Lakehouse的服务实例。B企业即可立即使用A企业共享的数据。
+
+## 注意事项
+
+* 分享的数据均为“只读”，不允许消费方对数据进行修改、删除等操作。
+* 创建share对象的工作空间决定了该share对象所能添加的数据对象范围。不支持跨工作空间添加数据对象。
+* 一个share对象中最多分享1000个table或view对象。
+* 如需对一个table中的部分数据进行分享，建议根据分享数据的需要，创建对应的view视图，然后将view视图进行分享。
+* 分享的数据禁止数据消费方进行二次分享，以保护数据提供方的权益。
+* 目前不能阻止数据消费方对分享数据的复制行为，因此需要数据提供方谨慎选择分享数据的范围。
+
+## 数据分享的DDL命令
+
+[CREATE SHARE](create-share.md)
+
+[ALTER SHARE](alter-share.md)
+
+[GRANT TO SHARE](grant-to-share.md)
+
+[REVOKE FROM SHARE](revoke-from-share.md)
+
+[SHOW SHARES](show-shares.md)
+
+[DESC SHARE](desc-share.md)
+
+[DROP SHARE](drop-share.md)
+
+## 支持share的数据对象
+
+当前支持share的数据对象有：table和view对象。
+
+支持使用 all tables in schema \<schema\_name> 和 all views in schema \<schema\_name> 的方式，将指定schema下的所有table和view对象加入到共享对象share中。 该操作包含“未来”创建在指定schema中的所有table和view对象，请谨慎操作。
+
+## 提供数据分享的操作
+
+### Web端
+
+**1. 创建share对象**
+
+为保障数据安全，数据分享（share）对象必须由具备“实例管理员”（instance\_admin）角色的用户创建。点击左侧菜单的“数据管理”-“数据分享”，进入数据分享列表页。
+
+点击“+新增分享”，打开新建数据分享窗口：
+
+:-: ![](.topwrite/assets/image_1734492957409.png =507)
+
+1）填写数据分享的“分享名称”。
+
+2）选择“工作空间”，指将要分享的table或view所在的工作空间，一个数据分享（share）对象仅可包含一个工作空间下的数据。
+
+3）在数据对象行，点击“添加”。选择数据分享中需要包含的具table或view，可以选择多个。但请注意，不可选择来源于其他数据分享的表和视图，因为数据分享的授权中不允许对数据进行二次分享。使用web端创建的数据分享仅支持包含已存在的table和view，暂不支持指定整个schema下“未来”创建的table或view对象。
+
+4）在接收实例行，点击“添加”。输入需要接收数据的服务实例名称。服务实例名称在Lakehouse服务中全局唯一。服务消费端用户可在首页右侧或在服务实例的URL中找到自己的服务实例名称并提供给分享者进行配置。
+
+:-: ![](.topwrite/assets/share_img_instancename.png =786)
+
+^
+
+*注意*：
+
+1. *为保障以工作空间为隔离域的数据安全，仅具备工作空间管理员角色的用户可在数据分享（share）中添加其管理的工作空间内的数据对象*。
+2. *创建数据分享（share）对象弹窗中的“创建”和“添加数据”是两个操作，即使添加要分享的数据全部失败或部分失败，并不会影响分享对象的创建。任意操作出现失败时，会返回报错信息。你可以在数据分享列表中点击已创建的数据分享，继续添加数据对象或要接收数据的服务实例*。
+
+**2. 查询已创建数据分享（share）对象**
+
+所有当前服务实例内已创建的数据分享（share）对象，均在“数据分享”列表页显示。具备服务实例管理员角色（instance\_admin)或工作空间管理员角色（workspace\_admin)的用户，可以查看数据分享（share）对象列表。
+
+:-: ![](.topwrite/assets/image_1734493289109.png =737)
+
+**3. 查询数据分享（share）详情**
+
+在“数据分享”列表页显示点击具体的数据分享名称，即可查询该数据分享的详细信息，包括基础信息、接收分享的服务实例以及分享的数据对象。具备服务实例管理员角色（instance\_admin)或工作空间管理员角色（workspace\_admin)的用户，可以查看数据分享（share）对象的详情。
+
+:-: ![](.topwrite/assets/image_1734493331354.png =735)
+
+**4. 添加/删除分享的数据对象**
+
+数据分享所属空间的空间管理员角色用户，可以添加或删除该数据分享中的数据对象（table或view）。
+
+在数据分享列表页，点击要添加数据对象的share对象名称，进入share对象详情页面。点击“编辑”按钮，在弹窗中选择要添加或删除的数据对象。点击“确定”完成分享数据对象的更新。不可添加来源于其他share对象的数据。
+
+添加后的数据对象会立即被share对象的消费者可见，出现在其提取数据的schema中。
+
+:-: ![](.topwrite/assets/image_1734493367553.png =721)
+
+**5. 配置share的分享目标**
+
+需要对share对象配置被分享的服务实例名称（instance\_name）才可完成数据分享。服务实例名称需要数据消费端提供。
+
+:-: ![](.topwrite/assets/image_1734493417202.png =771)
+
+^
+
+**6. 删除share对象**
+
+具备服务实例管理员角色（instance\_admin)角色的用户，或该数据分享所属空间的工作空间管理员角色（workspace\_admin)的用户，可以删除数据分享对象。
+
+在数据分享列表页或数据分享详情中，点击“操作”中的“删除”按钮，即可完成数据分享对象的删除。share对象一经删除不可恢复。数据消费端会立即失去对被分享数据的使用权限。
+
+### 使用SQL操作
+
+**1. 创建share对象**
+
+为保障数据安全，share对象必须由具备“实例管理员”（instance\_admin）角色的用户创建。创建share对象时，需要在计划分享数据的工作空间中执行以下语句：
+
+```SQL
+CREATE SHARE <share_name>;
+```
+
+***
+
+**2. 向share对象添加要分享的数据对象**
+
+创建出的share对象初始不包含任何数据对象，需要通过 Grant 语句添加需要分享的数据对象，语法为：
+
+```SQL
+GRANT select, read metadata ON {TABLE <table_name> | VIEW <view_name>} TO SHARE <share_name>;
+```
+
+例如：
+
+```SQL
+GRANT select, read metadata ON TABLE share_demo_table TO SHARE share_demo;
+```
+
+可以使用all tables in schema 或 all views in schema方式将指定schema下当前和未来所有table或view对象添加至share中，例如：
+
+```SQL
+Grant select, read metadata on ALL tables in SCHEMA share_demo_schema TO SHARE share_demo;
+Grant select, read metadata on ALL views in SCHEMA share_demo_schema TO SHARE share_demo;
+```
+
+向share对象添加要分享的数据对象时，执行操作的用户必须具备分享涉及table或view对象的select （查询）和 read metadata （查看元数据）权限，并可以进行二次授权 （with grant option）。工作空间管理员角色（workspace\_admin）天然具备上述权限。
+
+需要取消share对象中分享的数据对象时，可通过revoke语句实现：
+
+```SQL
+REVOKE select, read metadata on {TABLE <name> | VIEW <name>} FROM SHARE <share_name>;
+```
+
+注意：当分享table或view对象时，由于table或view对象一定存在于一个schema对象下，所以该schema的元数据权限（read metadata）也会被自动添加至该share对象中。当取消share中的table或view对象时，其所属schema的元数据权限也会被自动移除。
+
+***
+
+**3. 配置share的分享目标**
+
+需要对share对象配置被分享的服务实例名称（instance\_name）才可完成数据分享。服务实例名称需要数据消费端提供。
+
+服务实例名称在Lakehouse服务中全局唯一。服务消费端用户可在首页右侧或在服务实例的URL中找到自己的服务实例名称并提供给分享者进行配置。
+
+:-: ![](.topwrite/assets/share_img_instancename.png =786)
+
+数据分享者配置share分享目标的语法如下:
+
+```SQL
+ALTER SHARE <share_name> [ADD | REMOVE] INSTANCE <instance_name>; 
+```
+
+其中ADD为添加，REMOVE为移出。该操作即时生效，可随时对share添加或移出分享目标实例。一个share对象可以分享给多个服务实例。
+
+完成上述三步操作后，即完成了数据向指定服务实例的分享。
+
+^
+
+**4. 查询已创建share对象**
+
+可以通过执行show命令查询已创建的share对象，语法如下：
+
+```SQL
+SHOW SHARES;
+```
+
+返回结果示例如下：
+
+:-: ![](.topwrite/assets/share_img_showshares.png =803)
+
+其中：
+
+* provider为share提供者的租户名；
+* provider\_instance为share提供者的服务实例名；
+* provider\_workspace为share所属的工作空间；
+* scope为share的分享范围，当前仅支持PRIVATE——指定instance分享；
+* to\_instance为该share对象指定被分享至的服务实例名称，多个服务实例名称之间用英文逗号(,)分隔；
+* kind为share的类型，OUTBOUND为当前服务实例分享出的数据，INBOUND为其他服务实例分享至当前服务服务实例的数据。
+
+^
+
+**5. 查询指定share分享的数据对象**
+
+可以执行以下语句查询share中已被授予的数据对象：
+
+```SQL
+DESC SHARE <share_name>;
+```
+
+返回结果示例如下：
+
+:-: ![](.topwrite/assets/share_img_descshare.png =798)
+
+^
+
+**6. 删除share对象**
+
+可执行以下命令删除当前服务实例创建的share对象：
+
+```SQL
+DROP SHARE <share_name>;
+```
+
+share对象一经删除不可恢复。数据消费端会立即失去对被分享数据的使用权限。
+
+## 使用被分享数据的操作
+
+### Web端
+
+**1.查询被分享数据**
+
+使用具备服务实例管理员（instance\_admin）角色或工作空间管理员（workspace\_admin）角色的用户，在“数据分享”菜单的“分享给我”页签中，能够查看到所有分享给当前服务实例的数据分享对象。
+
+点击数据分享对象名称，可以查看该数据分享的来源、接收时间以及该数据分享中当前所包含的数据（table或view）。
+
+:-: ![](.topwrite/assets/image_1734493496334.png =777)
+
+^
+
+**2.提取被分享share创建schema**
+
+在“分享给我”的列表页，或数据分享对象的详情页面，点击“提取”按钮，即可提取该分享中的数据。
+
+:-: ![](.topwrite/assets/image_1734493713534.png =793)
+
+提取数据时，只能以schema为单位提取，暂不支持单独提取table或view。
+
+:-: ![](.topwrite/assets/image_1734493642759.png =541)
+
+首先需要选择“源schema”，即需要提取该分享中哪些schema的数据。如果数据分享中包含多个schema，需要操作多次提取。
+
+然后选择数据提取目标的工作空间，并输入存放数据的schema名称。数据提取操作将在该工作空间中新建一个schema，并存放源schema中的数据。注意，该schema被创建后为“只读”schema，不可在此schema中新建其他数据对象。
+
+完成上述选择和输入后，点击“确定”即可完成数据提取。
+
+**3. 使用被分享数据**
+
+完成数据提取操作后，即可在指定创建的schema下看到share对象中该schema下分享的所有table和view对象。并可以对这些table、view对象执行select查询或与其他table、view进行join查询。
+
+被分享数据在“数据”栏中以特殊图标标识，以便区分。
+
+:-: ![](.topwrite/assets/image_1734493884869.png =279)
+
+### 使用SQL操作
+
+**1. 查询被分享数据**
+
+数据消费方可通过show shares命令查询被分享的share对象。使用方式和返回结果与提供数据分享的第3步一致。
+
+进一步，可通过desc shares命令，查询被分享的share中包含哪些schema和table对象。
+
+^
+
+**2. 使用被分享share创建schema**
+
+通过share分享的数据，需要在消费端创建对应的schema才可查询和使用。操作语句如下：
+
+```SQL
+CREATE SCHEMA <schema_name> FROM SHARE <provider_instance>.<share_name>.<schema_name>;
+```
+
+其中\<provider\_instance>和\<share\_name>可通过show shares命令的查询结果获得；\<schema\_name>可通过desc share \<share\_name>命令指定share名称查询获得。
+
+Create schema \<schema\_name>中的schema名称可以自行定义，不必与share中的schema名称相同。
+
+执行上述命令时，操作者必须具备在执行操作的工作空间创建schema的权限。工作空间管理员角色（workspace\_admin）默认具备上述权限。
+
+^
+
+**3. 使用被分享数据**
+
+完成create schema from share 的执行后，即可在指定创建的schema下看到share对象中该schema下分享的所有table和view对象。并可以对这些table、view对象执行select查询或与其他table、view进行join查询。
+
+## share对象的权限
+
+**1. 提供者权限**
+
+仅服务实例管理员（instance\_admin）角色的用户可以创建数据共享（share）对象。执行创建
+
+share对象的权限点如下，暂不支持使用grant 语句将share对象的权限授予其他角色或用户。
+
+| **权限点**                                                         | **说明**                                                                        |

+| Alter share                                                     | 修改share 对象，添加或删除被分享的实例ID。                                                     |
+| Drop share                                                      | 删除share实例。                                                                    |
+| Read metadata                                                   | show shares和 desc share权限。其中desc share可返回share 中包含的object和授予的objectPrivilege。 |
+| Grant objectprivilege to shareRevoke objectprivilege from share | 为share添加或移出数据对象：Grant objectPrivilege to;Revoke objectPrivilege from。         |
+
+^
+
+**2. 消费者权限**
+
+工作空间中成员均具备share对象的use和read metadata权限。但必须具备在工作空间中的create schema权限才可以使用share中分享的数据创建出schema。
+
+| **权限点**       | **说明**                                        |

+# 数据源IP白名单配置指南
+
+## 应用场景
+
+当数据源部署在内网环境或具有严格的安全管控要求时，需在**源端数据库/服务器**配置 IP 白名单：
+
+1. 仅允许数据同步服务IP段访问源数据
+2. 防止未经授权的网络访问
+3. 满足企业网络安全审计要求
+
+## 前置准备
+
+* 确认目标数据源支持IP白名单机制
+* 获取数据同步服务所在服务器的公网IP地址
+* 确保具备数据源管理权限
+
+## 配置流程
+
+如果在配置数据源、测试连通性或者同步任务运行时，遇到因白名单限制导致的报错，可以按照此文档进行操作。
+
+### 步骤1：获取数据同步服务出口IP地址
+
+根据实际使用服务所在的云和地域，获取对应的IP地址：
+
+| 服务地域 | IP 地址 |
+| :--- | :--- |
+| 阿里云·上海 | 47.100.176.72 |
+| 阿里云·新加坡 | 47.237.31.114 |
+| 腾讯云·上海 | 110.40.220.6, 124.220.91.8, 101.34.216.184 |
+| 腾讯云·北京 | 101.42.151.242, 101.42.224.202, 43.138.11.31 |
+| 腾讯云·广州 | 43.138.226.127, 1.14.203.242, 175.178.164.94 |
+| 亚马逊云·北京 | 54.223.225.56, 52.80.208.69 |
+| 亚马逊云·新加坡 | 54.251.190.22, 13.250.195.227 |
+
+### 步骤2：源端数据库白名单配置
+
+1. **登录源数据库管理控制台**
+   * MySQL：通过安全组或数据库参数设置
+   * Oracle：通过 `SQLNET.ORA` 文件配置
+   * SQL Server：通过服务器防火墙设置
+
+2. **添加IP白名单规则**
+   以阿里云 RDS MySQL 版为例，以下是基于**阿里云控制台**界面的详细操作步骤：
+
+   **步骤 1：登录阿里云控制台**
+   打开浏览器，访问阿里云官网，使用您的阿里云账号登录。
+
+   **步骤 2：进入 RDS 管理控制台**
+   登录后，点击顶部菜单中的“**产品与服务**”，然后选择“**数据库**” > “**关系型数据库 RDS**”。
+
+   **步骤 3：选择目标 RDS 实例**
+   在 RDS 控制台页面，找到你想要操作的 RDS 实例。点击实例名称，进入实例详情页面。
+
+   **步骤 4：进入“白名单设置”**
+   在实例详情页面，找到左侧菜单中的“**安全设置**”。点击“**白名单设置**”选项。
+
+   **步骤 5：添加白名单**
+   在“白名单设置”页面，您会看到当前的白名单配置。点击“**添加白名单分组**”按钮，或在已有的白名单分组中直接添加 IP 地址。
+
+   **步骤 6：配置白名单**
+   在弹出的对话框中，输入白名单分组名称（可选）。在“**白名单内容**”框中，输入允许访问的 IP 地址或 IP 段。可以输入多个 IP 地址或 IP 段，用英文逗号分隔，例如：`47.100.176.72`。然后点击“**确定**”完成添加。
+
+   **步骤 7：保存白名单设置**
+   添加完成后，点击页面底部的“**保存**”按钮，保存白名单设置。
+
+### 步骤3：数据同步验证
+
+1. 在数据源配置中，点击“测试连通性”。如果成功，通常表明配置已生效。
+2. 为保险起见，可以创建测试同步任务并手动执行。
+3. 观察任务日志是否显示连接成功。
+4. 失败时检查同步任务日志和数据库审计日志。
+
+## 注意事项
+
+具体配置方式可能因数据源类型（MySQL/Oracle等）而异，请参考对应数据源的官方文档。如需访问云产品，请前往各云产品帮助中心查看其添加白名单的注意事项。白名单设置通常会立即生效，但也可能需要几分钟。
+
+## 常见问题
+
+### Q1：已添加 IP 白名单仍无法连接
+
+* 检查 IP 地址是否准确（建议通过 `curl ifconfig.me` 验证出口 IP）
+* 确认数据源防火墙已开放对应端口
+* 检查白名单配置是否已生效（部分数据库需重启生效）
+
+### Q2：白名单维护最佳实践
+
+1. 为数据同步服务单独创建访问账号。
+2. 按最小权限原则配置访问范围。
+3. 定期审计白名单中的IP地址。
+4. 建议配合VPN/专线提升安全性。
+5. 不要将 `0.0.0.0/0`（允许所有 IP 访问）添加到生产环境的白名单中，除非绝对必要。

+# 数据类型转换
+
+在 SQL 语句中，数据类型转换是一项常见的操作。本文将介绍如何在 SQL 中进行数据类型转换，以及相关的函数和语法。
+
+## 数据类型转换函数
+
+### CAST 函数
+
+CAST 函数用于将一个数据类型的值转换为另一个数据类型的值。如果转换过程中超出目标数据类型的范围，则会引发溢出异常。
+
+#### 语法
+
+```
+CAST(expression AS type)
+```
+
+参数说明：
+
+* expression：必填。待转换的数据源。
+* type：必填。目标数据类型。用法如下：
+  * `CAST(double AS bigint)`：将 DOUBLE 数据类型值转换为 BIGINT 数据类型。
+  * `CAST(string AS bigint)`：将字符串转换为 BIGINT 数据类型。如果字符串中是整型表达的数字，则直接转换为 BIGINT 类型。如果字符串中是浮点数或指数形式表达的数字，则先转换为 DOUBLE 数据类型，再转换为 BIGINT 数据类型。
+  * `CAST(string AS timestamp)` 或 `CAST(timestamp AS string)`：会采用默认的日期格式 `yyyy-MM-dd HH:mm:ss`。
+
+#### 示例
+
+```sql
+SELECT CAST(rand() AS INT);
+-- 执行结果 0
+```
+
+### TYPE(expr)
+
+ 函数用于将一个值从一种数据类型转换为另一种数据类型。如果转换成功，返回转换后的值；如果转换失败，默认返回 NULL。
+
+#### 语法
+
+```
+TYPE(expr)
+```
+
+参数说明：
+
+* TYPE类型：支持float\double\tinyint\smallint\int\bigint\string\date\timestamp\timestamp\_ntz\binary\boolean
+* expr：必填。要转换的表达式。
+
+#### 示例
+
+```sql
+SELECT binary('1');
+-- 执行结果 [31]
+```
+
+```sql
+SELECT INT(100.6);
+-- 执行结果 100
+```
+
+## 转换运算符
+
+除了使用函数进行数据类型转换外，还可以使用转换运算符。
+
+### 语法
+
+```
+expression::type
+```
+
+* expression：必填。要转换的表达式。
+* type：必填。目标数据类型。
+
+### 示例
+
+```sql
+SELECT 123.45::INT;
+-- 执行结果 123
+
+SELECT '2021-08-15'::DATE;
+-- 执行结果 2021-08-15
+```
+
+## 转换运算符
+
+除了使用函数进行数据类型转换外，还可以使用转换运算符。
+
+### 语法
+
+```
+expression::type
+```
+
+* expression：必填。要转换的表达式。
+* type：必填。目标数据类型。
+
+### 示例
+
+```
+SELECT 123.45::INT;
+-- 执行结果 123
+
+SELECT '2021-08-15'::DATE;
+-- 执行结果 2021-08-15
+```

+# 数据类型转换
+
+数据类型转换是指将一种数据类型的值转换为另一种数据类型的值的过程。数据类型转换可以分为隐式转换和显式转换。隐式转换是指在执行某些操作时，系统自动进行的数据类型转换，例如算术运算、比较运算、函数调用等。显式转换是指用户使用特定的函数或语法来指定数据类型转换，例如CAST等。不同的数据库系统可能有不同的数据类型转换规则和函数。本文将介绍lakehouse的数据类型转换特点和用法
+
+# 显式转换
+
+Lakehouse支持两种方式进行显式类型转换：使用 `CAST` 函数或使用 `::` 符号。这两种方式是等价的，例如 `CAST(a AS INT)` 等价于 `a::INT`。`::` 符号提供了更简洁的语法来执行类型转换。
+
+下图显示使用cast转换的行为，

+
+黑色加粗代表可能会报错或者转换为null，需要说明lakehouse为了避免用户写SQL转换值失败，采用了转换更宽松的行为，黑色加粗部分引发异常会转换为null，当然你也可以设置标准行为黑色加粗部分为严格模式也可以报错,开启严格模式set cz.sql.cast.mode=strict;开启后你可以直接使用[try\_cast](datatype-cast.md)函数报错行为将返回null，详情可以参考参数管理
+
+* CAST(Numeric AS Numeric)：如果超出目标数据类型的范围，lakehouse默认会转换为null
+* 将 FLOAT 转换为 INTEGER 对值进行截断
+* 将 TIMESTAMP 转换为 DATE 会删除有关一天中时间的信息
+
+# 隐式转换
+
+当两个不同类型的值进行算术运算或比较运算时，Lakehouse SQL会按照一定的优先级进行隐式转换，以保证运算结果的精度和范围。优先级的顺序如下图。也就是说，如果两个值的类型不同，那么类型较低的值会被转换为类型较高的值，以匹配另一个值的类型。例如，当整数和小数进行加法运算时，整数会被转换为小数，以避免精度损失。当日期和时间戳进行比较运算时，日期会被转换为时间戳，以保证时间粒度的一致性。
+
+![](.topwrite/assets/image_1700219556792.png)
+
+图中类型由低到高排布最上层为最低类型
+
+**特别注意**
+
+lakehouse为了避免用户写SQL转换值失败，隐式转换和显式转化采用了转换更宽松的行为，引发异常会转换为null。你可以开启严格模式set cz.sql.cast.mode=strict;详情可以参考参数管理
+比如
+
+```
+--18.234超过了指定的转化范围，使用cast转化如果没有开启严格模式结果为null
+SELECT cast(18.234 AS decimal(4, 3)) AS res;
++------+
+| res  |
++------+
+| null |
++------+
+--开启严格模式，则会报错精度异常
+set cz.sql.cast.mode=strict;
+SELECT cast(18.234 AS decimal(4, 3)) AS res;
+CZLH-22003:[1,8] cannot cast `18.234` to decimal32 due to an overflow. Use `try_cast` to tolerate overflow. Detail  taskId 0
+
+```
+
+# 案例
+
+隐示转换
+
+```SQL
+--decimal和double运算
+SELECT typeof(10bd +3.14D) ;
++----------------------+
+| typeof(10BD + 3.14D) |
++----------------------+
+| double               |
++----------------------+
+```
+
+显示转换
+
+```SQL
+SELECT CAST(‘123’ AS INT) 
+```

+### 日期时间格式
+
+#### 概述
+
+在处理和展示日期时间信息时，正确地格式化和解析这些信息至关重要。CZ 提供了一系列日期时间格式符号，以便用户根据不同的需求来格式化、表示和处理日期时间数据。
+
+#### 日期时间格式符号
+
+| 符号 | 描述 | 支持类型 | 示例 |
+|:----:|:----:|:-------:|:----:|
+| y   | 年份 | 4位数字 | 2022  |
+| M   | 月份 | 1位或2位数字 | 3; 03  |
+| d   | 日期 | 1位或2位数字 | 5; 05  |
+| H   | 小时（24小时制） | 1位或2位数字 | 10; 23 |
+| m   | 分钟 | 1位或2位数字 | 5; 59  |
+| s   | 秒 | 1位或2位数字 | 8; 59  |
+| S   | 毫秒/微秒 | 1至6位数字 | 324123; 123456 |
+| '   | 字符常量 | 文本 | 'yyyy' |
+
+#### 详细说明
+
+1. 年份 (y)
+   - `yyyy`：表示四位数的年份，例如 2022。
+
+2. 月份 (M)
+   - `M`：表示不带前导零的月份。
+   - `MM`：表示带前导零的月份，例如 03 或 12。
+
+3. 日期 (d)
+   - `d`：表示不带前导零的日期。
+   - `dd`：表示带前导零的日期，例如 05 或 20。
+
+4. 小时（24小时制，H）
+   - `H`：表示不带前导零的小时。
+   - `HH`：表示带前导零的小时，例如 01 或 23。
+
+5. 分钟 (m)
+   - `m`：表示不带前导零的分钟。
+   - `mm`：表示带前导零的分钟，例如 04 或 59。
+
+6. 秒 (s)
+   - `s`：表示不带前导零的秒。
+   - `ss`：表示带前导零的秒，例如 08 或 59。
+
+7. 毫秒/微秒 (S)
+   - `S`：表示毫秒和微秒，可以是1至6位数字。从左到右依次为毫秒（3位）、微秒（3位）。纳秒（3位）在 CZ 中会被忽略。如果 S 的位数不足 6 位，则从右边开始降低精度。CZ 目前只支持微秒级别的时间戳精度。
+
+8. 字符常量 (')
+   - `'`：用于插入文本字符，例如 `'你好世界'`。
+
+#### 示例
+
+以下是一些使用不同日期时间格式的示例：
+
+1. `yyyy-MM-dd HH:mm:ss.SSSS`：2022-01-10 10:05:02.123456
+2. `yyyy/MM/dd HH:mm:ss.SSSS`：2022/01/10 10:05:02.123456
+3. `yyyy年MM月dd日 HH时mm分ss秒SSS毫秒`：2022年01月10日 10时05分02秒123毫秒
+4. `'今天是y年MM月dd日 d天' HH:mm:ss.SSSS`：今天是2022年01月10日 5天 10:05:02.123456
+5. `yyyy'你好世界'yMdH'-MM-dd HH:mm:ss.SSSS`：2022你好世界yMdH-01-10 10:05:02.123456
+
+通过上述格式符号和示例，用户可以灵活地根据需要创建和解析日期时间字符串。请注意，在解析时间字符串时，系统会根据格式符号的要求来解析每个部分。如果输入的字符串与指定的格式不匹配，将无法正确解析日期时间信息。因此，请确保输入的字符串严格遵循所选的日期时间格式。

+
+```bash
+python -c "
+from datus.tools.db_tools.db_manager import DBManager
+from datus.configuration.agent_config import DbConfig
+import os
+from dotenv import load_dotenv
+
+# 加载环境变量
+load_dotenv()
+
+# 创建数据库配置
+db_config = DbConfig(
+    type='clickzetta',
+    service=os.getenv('CLICKZETTA_SERVICE'),
+    username=os.getenv('CLICKZETTA_USERNAME'),
+    password=os.getenv('CLICKZETTA_PASSWORD'),
+    instance=os.getenv('CLICKZETTA_INSTANCE'),
+    workspace=os.getenv('CLICKZETTA_WORKSPACE'),
+    schema=os.getenv('CLICKZETTA_SCHEMA'),
+    vcluster=os.getenv('CLICKZETTA_VCLUSTER')
+)
+
+# 测试连接
+namespaces = {'lakehouse': {'lakehouse': db_config}}
+db_manager = DBManager(namespaces)
+
+try:
+    connector = db_manager.get_conn('lakehouse', 'lakehouse')
+    result = connector.test_connection()
+    print('✅ 云器Lakehouse连接测试成功！')
+    print(f'连接结果: {result}')
+except Exception as e:
+    print(f'❌ 连接测试失败: {e}')
+"
+```
+
+## 第七步：启动Datus
+
+### 方式一：命令行模式
+
+```bash
+# 启动交互式CLI
+datus-cli --namespace lakehouse --config conf/agent.yml
+```
+
+### 方式二：Web模式（推荐，支持subagent选择）
+
+```bash
+# 启动Web界面，支持选择不同的subagent
+datus-cli --namespace lakehouse --config conf/agent.yml --web --host 0.0.0.0
+
+# 或者只在本地访问
+datus-cli --namespace lakehouse --config conf/agent.yml --web --host 127.0.0.1
+```
+
+**Web 模式启动后**：
+
+* 默认访问地址：<http://localhost:8501> 或 <http://0.0.0.0:8501>
+* 在Web界面中可以选择之前创建的subagent进行对话
+* 支持更直观的交互界面
+
+**启动成功后的界面**：
+
+**CLI 模式**：
+
+```
+Initializing AI capabilities in background...
+
+Datus - AI-powered SQL command-line interface
+Type '.help' for a list of commands or '.exit' to quit.
+
+Namespace lakehouse selected
+Connected to lakehouse using database quick_start
+Context: Current: database: quick_start
+Type SQL statements or use ! @ . commands to interact.
+Datus>
+```
+
+**Web模式**：
+
+* 终端显示服务器启动信息和访问地址
+* 浏览器打开对应地址即可看到Web界面
+* Web界面左侧显示可选择的subagent列表
+* 点击选择subagent后即可开始对话
+
+## 第八步：开始使用（命令行方式）
+
+![](/.topwrite/assets/image_1764226910096.png)
+
+### 查看可用表
+
+```sql
+Datus> .tables
+```
+
+### 使用自然语言查询
+
+```
+Datus> / 显示所有用户表的统计信息
+```
+
+### 执行SQL查询
+
+```sql
+Datus> SELECT * FROM your_table LIMIT 10;
+```
+
+### 获取帮助
+
+```
+Datus> .help
+```
+
+
+
+### Web方式
+
+![](/.topwrite/assets/image_1764227961202.png)
+
+Web 方式启动页面如上。如果在命令行方式下增加了 SubAgent，则首页就会显示。
+直接输入聊天内容则以 Agent 模式运行（不会调用 MCP Tools）。选择具体的 SubAgent 后则以 SubAgent 模式进行对话，会调用 MCP Tools。
+
+![](/.topwrite/assets/image_1764228154353.png)
+
+### 多模型配置
+
+为不同任务使用不同模型：
+
+```yaml
+agentic_nodes:
+  quick_query:
+    model: qwen_main         # 快速查询使用基础模型
+    # ... 其他配置
+
+  complex_analysis:
+    model: qwen_reasoning    # 复杂分析使用推理模型
+    enable_thinking: true
+    # ... 其他配置
+```
+
+## 常见问题
+
+### Q: 连接云器Lakehouse失败
+
+**A**：请检查：
+
+1. 网络连接是否正常
+2. `.env` 文件中的凭据是否正确
+3. 云器 Lakehouse 服务是否可访问
+4. 实例ID、工作空间等参数是否正确
+
+### Q: AI模型响应缓慢
+
+**A**：可以尝试：
+
+1. 切换到更快的模型（如 `qwen-plus` → `qwen-turbo`）
+2. 减少 `max_context_length` 等参数
+3. 启用GPU加速（如果可用）
+
+### Q: 查询结果不准确
+
+**A**：建议：
+
+1. 增加 `schema_linking_rate` 到 `slow` 以获得更精确的模式匹配
+2. 在查询中提供更多上下文信息
+3. 使用 `.schema tablename` 查看表结构后再查询
+
+### Q: 如何切换不同的数据库实例
+
+**A**：
+
+1. 修改 `.env` 文件中的 `CLICKZETTA_*` 变量
+2. 重新启动 `datus-cli`
+3. 或者在配置中添加多个namespace配置

+## 默认值
+
+### 语法
+
+```SQL
+CREATE TABLE [ IF NOT EXISTS ] table_name
+(
+    column_definition DEFAULT default_expression, [column_definition,...]
+)
+[ PARTITIONED BY (column_name column_type | column_name ) ];
+```
+
+* **DEFAULT default_expression**：为新添加的列定义一个默认值。如果在 INSERT、UPDATE 或 MERGE 操作中未指定该列的值，将自动使用此默认值。对于添加列之前已存在的数据行，该列将填充为 null。支持非确定性函数（如 `current_date`、`random`、`current_timestamp`、上下文函数）和常量值。
+
+### 生成列和默认值区别
+
+1. **分区列支持**：
+   * **默认值**：当前不支持为分区列设置默认值。
+   * **生成列**：支持为分区列生成值。
+
+2. **函数支持**：
+   * **默认值**：支持使用非确定性函数，如 `current_timestamp()`。
+   * **生成列**：不支持非确定性函数，只能使用确定性的标量函数。
+
+3. **插入操作中的值指定**：
+   * **默认值**：在插入数据时，可以为列指定一个静态值，如果未指定，则使用默认值。
+   * **生成列**：在插入数据时，不能为生成列指定值，其值完全由生成表达式决定。
+
+4. **列值来源**：
+   * **默认值**：不支持列的值来自其他列的转换。
+   * **生成列**：支持列的值来自其他列的转换，即可以基于其他列的值计算生成。
+
+5. **现有数据行的处理**：
+   * **默认值**：当为现有表添加带有默认值的列时，已存在的数据行中的该列将填充为 null。
+   * **生成列**：对于已存在的数据行，生成列的值将根据生成表达式进行计算，并显示计算结果。
+
+### 使用限制
+
+* 不支持分区列使用默认值。
+* 支持批量接口写入，包括Studio数据集成的批量导入。实时接口写入时默认值不会生效，因为调用实时接口时必须指定所有的列。
+* 不支持类似生成列中可以引用其他列的函数方式。
+
+### 插入数据
+
+```SQL
+CREATE TABLE t_default
+(
+    id   int,
+    col1 string DEFAULT current_timestamp (),
+    col2 string DEFAULT '1',
+    col3 int    DEFAULT 1,
+    clo4 json   DEFAULT '1',
+    col5 DOUBLE DEFAULT random(),
+    col6 date   DEFAULT current_date()
+);
+INSERT INTO t_default (id) VALUES (1);
+```
+
+## 添加字段时指定默认值
+
+### 语法
+
+```SQL
+-- 添加列
+ALTER TABLE table_name ADD COLUMN
+      column1_name_identifier data_type [column_properties]
+      [FIRST | AFTER column1_name_identifier]  ,....
+
+column_properties:==
+    DEFAULT default_expression |
+    COMMENT column_comment 
+```
+
+* **DEFAULT default_expression**：为新添加的列定义一个默认值。如果在 INSERT、UPDATE 或 MERGE 操作中未指定该列的值，将自动使用此默认值。对于添加列之前已存在的数据行，该列将填充为 null。
+
+### 使用限制
+
+* 不支持为已有的列添加默认值。
+
+### 示例
+
+#### 添加列并指定默认值
+
+```SQL
+ALTER TABLE my_table ADD COLUMN
+    new_col INT DEFAULT 0 AFTER existing_col;
+```
+
+在这个例子中，`new_col` 将被添加到 `existing_col` 后面，并且所有现有数据行的 `new_col` 将被设置为默认值 null。

+## DELTA LAKE
+Delta Lake 是一个开源的大数据框架，用于提供数据湖上的可靠性和性能。它建立在 Apache Spark 和其他大数据处理引擎之上，为存储在数据湖中的数据提供了一种结构化存储层，使得数据湖可以像数据仓库一样易于使用。Lakehouse 提供了外部表的方式来访问该格式数据。
+
+
+## 创建DELTA格式外部表
+
+[创建外部表语法](<create-external-table.md>)
+
+### **示例**
+
+```SQL
+--创建conneciton
+CREATE STORAGE CONNECTION if not exists oss_delta
+    TYPE oss
+    ENDPOINT = 'oss-cn-beijing.aliyuncs.com'
+    access_id = 'xxx'
+    access_key = 'xxxx'
+    comments = 'delta';
+
+--创建外部表,使用上面的连接信息
+CREATE EXTERNAL TABLE IF NOT EXISTS sales_data
+(
+  order_id INT,
+  product_id STRING,
+  sale_amount DOUBLE
+)
+PARTITIONED BY (dt STRING)
+USING DELTA
+CONNECTION oss_delta
+LOCATION 'oss://my-bucket/data/sales'
+COMMENT 'External table for sales data stored in OSS';
+```
+
+## 删除外部表
+
+```SQL
+DROP TABLE [ IF EXISTS ] [schema_name.]<table_name>
+```
+
+**参数说明**
+
+* `IF EXISTS`：可选，如果指定的表不存在，系统不会报错。
+* `schema_name`：可选，指定 schema 的名称。如果未指定，默认使用当前用户的 schema。
+* `table_name`：要删除的表名称。
+
+**说明**
+
+* 删除外部表并不会删除数据，因为数据存储在外部系统中，删除操作只会删除表的映射信息。
+
+**示例**
+
+```SQL
+--删除已经创建的外部表
+DROP TABLE sales_data;
+--删除名为 sales_data 的表，如果表不存在，不报错：
+DROP TABLE IF EXISTS sales_data;
+--删除名为 my_schema 下的 sales_data表
+DROP TABLE my_schema.my_table;
+```
+
+## 查看外部表详情
+
+```SQL
+DESC[RIBE] [TABLE] [EXTENDED] table_name;
+```
+
+**参数说明**
+
+* **DESC\[RIBE]**：DESC和DESCRIBE可以互换使用，都表示描述表结构的命令。
+* **TABLE**：可选参数，用于指定查看表结构的类型，如BASE TABLE或VIEW等。
+* **EXTENDED**：可选参数，加入此关键字后，可以展示更多扩展信息，如表的创建语句和Location信息等。
+* **table\_name**：指定需要查看结构的表名。
+
+## 修改外部表
+
+### 重命名表
+
+通过ALTER TABLE命令，您可以将现有的表重命名为新的表名。
+
+**语法**
+
+```SQL
+ALTER TABLE name RENAME TO new_table_name;
+```
+
+**示例**
+
+```SQL
+ALTER TABLE old_table_name RENAME TO new_table_name;
+```
+
+### 修改表注释
+
+通过ALTER TABLE命令，您可以为表添加或修改注释。
+
+**语法**
+
+```SQL
+ALTER TABLE tbname SET COMMENT '';
+```
+
+**示例**
+
+```SQL
+ALTER TABLE scores SET COMMENT '这是一个成绩表';
+```
+## **外部表计费**
+
+* **存储费用**： 外部表不产生存储费用，因为数据不存储在 Lakehouse 中。
+* **计算费用**： 使用外部表进行计算会消耗计算资源，因此会产生计算费用。
+
+## **外部表权限**
+
+外部表和内部表权限点相同。由于外部表无法执行 INSERT、UPDATE、TRUNCATE、DELETE、UNDROP 等操作，所以没有对应的操作权限点。
+
+* **创建权限**： 需要具有创建表（create table）的权限。
+* **删除权限**：需要具有删除（DROP）权限。
+* **读取权限**： 需要具有选择（select）权限。
+
+## **使用注意事项**
+
+* **连接配置**： 创建 connection 时，确保 endpoint 配置正确，以便 Lakehouse 能够成功连接。如果 Lakehouse 和对象存储位于同一云服务且在同一区域，通常使用内网地址即可实现网络互通。如果不在同一网络环境，建议使用对象存储的公网地址。
+## 具体案例
+
+### 连接阿里云Oss
+
+```SQL
+--创建connection,用于连接对象存储
+CREATE STORAGE CONNECTION  oss_delta
+    TYPE oss
+    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com'
+    access_id = 'xxxxxx'
+    access_key = 'xxxxxx'
+    comments = 'delta'
+    ;
+--使用上面的链接信息，创建外部表
+CREATE    EXTERNAL TABLE pepole_delta (id int, name string,dt string) 
+USING DELTA 
+CONNECTION oss_delta 
+PARTITIONED BY (dt ) 
+LOCATION 'oss://bucketmy/delta-format/uploaddelta/' 
+COMMENT 'edelta-external';
+```
+
+### 连接Google GCS
+
+Lakehouse 连接 Google Cloud Storage (GCS) 时，将使用服务账号密钥进行身份验证。请按照以下步骤操作：
+
+1. **获取服务账号密钥**：
+
+   - 登录 Google Cloud 控制台。
+   -  按照 *[Google Cloud 文档](https://cloud.google.com/docs/authentication/getting-started)* 的指导，创建并下载服务账号的 JSON 密钥文件。
+
+2. **配置 ****`private_key`**** 参数**：
+
+   - 打开下载的 JSON 密钥文件，将文件中的私钥内容完整复制。
+
+3. **注意**：
+
+   - 在配置 `private_key` 时，必须前面添加r,r代表区分大小写，殊字符和 unicode 字符都不会被转义。
+
+```SQL
+--创建connection,用于连接对象存储
+CREATE STORAGE CONNECTION  oss_delta
+    TYPE gcs
+    private_key=r'{
+  "type": "service_account",
+  "project_id": "PROJECT_ID",
+  "private_key_id": "KEY_ID",
+  "private_key": "-----BEGIN PRIVATE KEY-----\nPRIVATE_KEY\n-----END PRIVATE KEY-----\n",
+  "client_email": "SERVICE_ACCOUNT_EMAIL",
+  "client_id": "CLIENT_ID",
+  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
+  "token_uri": "https://accounts.google.com/o/oauth2/token",
+  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
+  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/SERVICE_ACCOUNT_EMAIL"
+}';
+--使用上面的链接信息，创建外部表
+CREATE    EXTERNAL TABLE pepole_delta (id int, name string,dt string) 
+USING DELTA 
+CONNECTION oss_delta 
+PARTITIONED BY (dt ) 
+LOCATION 'gs://bucketmy/delta-format/uploaddelta/'

+# 查看共享数据对象信息
+
+## 功能描述
+
+`DESC SHARE` 语句用于查询指定共享数据对象（share）中包含的具体数据对象，如表、视图和模式（schema）等。通过该语句，用户可以了解共享数据对象的详细信息，包括对象类型、名称、共享时间等。
+
+## 语法格式
+
+```
+DESC SHARE <instance_name>.<share_name>;
+```
+
+## 参数说明
+
+* **instance_name**：提供 share 的服务实例名称。`SHOW SHARES;` 语句中的 `provider_instance` 字段返回该名称。
+* **share_name**：需要查询的共享数据对象名称。
+
+## 返回说明
+
+* **kind**：添加到共享数据对象中的数据对象类型，通常包括 schema、table 和 view。
+* **name**：被分享的数据对象名称。对于 schema 类型，直接返回其名称；对于 table 和 view 类型，返回格式为 `<schema_name>.<table_name>` 或 `<schema_name>.<view_name>`。
+* **shared_on**：数据对象被添加到共享数据对象中的时间。
+
+## 使用示例
+
+以下是一些使用 `DESC SHARE` 语句的示例：
+
+1. 查询名为 `customer_data` 的共享数据对象中包含的数据对象信息：
+
+   ```
+   DESC SHARE customer_data;
+   ```
+
+   可能的返回结果：
+
+   ```
+   kind | name               | shared_on
+   -----|--------------------|----------
+   schema | customer           | 2022-01-01 10:00:00
+   table  | customer.orders     | 2022-01-02 14:30:00
+   view   | customer.order_summary | 2022-01-03 09:20:00
+   ```
+
+2. 查询从 instance_name 为 `share_demo` 的实例分享来的、名称为 `financial_data` 的共享数据对象中包含的表和视图信息：
+
+   ```
+   DESC SHARE share_demo.financial_data;
+   ```
+
+   可能的返回结果：
+
+   ```
+   kind | name                  | shared_on
+   -----|-----------------------|----------
+   table  | financial.transactions  | 2022-02-01 11:15:00
+   view   | financial.revenue_summary | 2022-02-02 16:45:00
+   ```
+
+通过以上示例，用户可以了解如何使用 `DESC SHARE` 语句查询共享数据对象的详细信息，并根据实际需求进行相应的操作。

+
+**云器 Lakehouse 作为 Provider 的独特定位**
+
+与传统单一功能的 Provider 不同，**云器 Lakehouse** 在 Dify 中扮演**多重 Provider 角色**：
+
+1\. **Vector Database Provider**: 提供HNSW向量索引、倒排索引、混合检索
+
+2\. **Storage Provider**: 提供Volume存储、多租户隔离、跨云兼容
+
+3\. **Compute Provider**: 提供弹性计算、SQL查询、数据处理能力
+
+这种"一个Provider，多重角色"的设计，正是湖仓一体架构的核心价值体现。
+

+
+**传统分离式 Provider 架构 vs. ClickZetta 统一 Provider 架构**：
+
+**现有方案的技术挑战**：
+
+:-: ![](.topwrite/assets/image_1756879734460.png =734)
+
+***
+
+**关键技术差异分析**：
+
+1\. **Provider集成复杂度**
+
+* 传统方案：需要配置Storage Provider（S3/OSS）+ Vector Provider（Qdrant/Milvus），维护双重数据映射
+* 云器Lakehouse方案：单一Provider同时提供Volume存储 + Vector索引，元数据自动同步
+
+2\. **一体化检索能力对比**
+
+**传统分离式方案**：
+
+```Python
+# 向量检索：Qdrant/Milvus
+vector_results = qdrant_client.search(vector=query_vector, limit=top_k)
+
+# 全文检索：需要Elasticsearch
+text_results = elasticsearch.search(query=text_query)
+
+# 混合检索：需要应用层融合
+combined_results = merge_and_rank(vector_results, text_results)
+```
+
+**云器 Lakehouse 湖仓一体方案**：
+
+```Python
+# 向量检索 - HNSW索引
+vector_results = client.execute("""
+    SELECT content, metadata, 
+           COSINE_DISTANCE(vector, CAST(? AS VECTOR(1536))) as score
+    FROM dataset_table 
+    ORDER BY score LIMIT ?
+""", [query_vector, top_k])
+
+# 全文检索 - 倒排索引 (中文分词)
+text_results = client.execute("""
+    SELECT content, metadata, SCORE(content) as score
+    FROM dataset_table 
+    WHERE MATCH_ALL(content, ?)
+    ORDER BY score DESC LIMIT ?
+""", [text_query, top_k])
+
+# SQL Like检索 - 降级备用
+like_results = client.execute("""
+    SELECT content, metadata, 0.5 as score
+    FROM dataset_table 
+    WHERE content LIKE ?
+    LIMIT ?
+""", [f"%{text_query}%", top_k])
+
+# 混合检索 - 单SQL统一处理
+hybrid_results = client.execute("""
+    SELECT content, metadata,
+           (COSINE_DISTANCE(vector, CAST(? AS VECTOR(1536))) * 0.7 + 
+            SCORE(content) * 0.3) as combined_score
+    FROM dataset_table 
+    WHERE MATCH_ALL(content, ?)
+    ORDER BY combined_score DESC LIMIT ?
+""", [query_vector, text_query, top_k])
+```
+
+3\. **性能优化策略对比**
+
+* pgvector: 限制≤2000维度，单机HNSW索引
+* Milvus: 分布式架构，需要独立集群运维
+* ClickZetta: 基于CRU弹性计算，自动资源调度，TPC-H基准测试性能领先9.84倍
+
+4\. **Provider配置跨云兼容性**
+
+```Python
+# 传统分离式Provider方案：跨云迁移需要修改多个Provider配置
+# 从AWS S3迁移到阿里云OSS
+STORAGE_TYPE = 's3'          # 需要改为 'aliyun-oss'
+AWS_ACCESS_KEY = '...'       # 需要改为 ALIYUN_OSS_ACCESS_KEY
+AWS_SECRET_KEY = '...'       # 需要改为 ALIYUN_OSS_SECRET_KEY
+VECTOR_STORE = 'qdrant'      # 向量Provider可能也需要调整
+
+# ClickZetta统一Provider方案：Volume抽象层屏蔽云存储差异
+STORAGE_TYPE = 'clickzetta-volume'  # 跨云不变
+VECTOR_STORE = 'clickzetta'         # 跨云不变
+CLICKZETTA_VOLUME_TYPE = 'user'     # 跨云不变
+# ClickZetta Provider后端自动适配底层云存储
+```
+
+^

+# 探索和分析数据湖Volume上的JSON文件里的数据
+
+## 1. 数据湖与JSON数据简介
+
+### 1.1 什么是数据湖（Data Lake）
+
+数据湖是Lakehouse的重要组成部分，允许您以原始格式存储所有结构化和非结构化数据，无需事先定义模式。这充分体现了湖仓一体的优势，将Lakehouse的数据管理扩展到对非结构化数据的一体化管理，不再局限于数据仓库中的结构化数据管理。这种灵活性使其成为大数据分析的理想选择，因为您可以根据需要使用不同的分析方法和工具来处理数据。数据湖通常由以下部分组成：
+
+* **存储层**：如对象存储（S3、OSS、COS等）
+* **元数据管理**：用于组织和发现数据
+* **处理引擎**：用于分析和转换数据
+
+### 1.2 数据湖中的Volume
+
+在Lakehouse等现代数据平台中，**Volume** 是一种抽象，它表示外部存储系统中的一个特定位置（例如对象存储中的一个路径）。Volume允许数据平台无缝访问存储在外部系统中的数据，而无需实际复制或移动这些数据。
+
+Volume的主要特点：
+
+* 直接连接到外部存储系统
+* 允许就地查询，无需ETL
+* 支持多种文件格式（JSON、CSV、Parquet等）
+* 可以与表进行集成，提供SQL访问能力
+
+### 1.3 JSON数据格式
+
+JSON（JavaScript Object Notation）是一种轻量级的数据交换格式，具有以下特点：
+
+* **半结构化**：灵活的键值对结构
+* **嵌套能力**：支持复杂的层次结构和数组
+* **广泛支持**：几乎所有编程语言都提供JSON解析支持
+* **人类可读**：相比二进制格式更容易理解
+
+在大数据领域，JSON被广泛用于存储事件数据、API响应、日志文件等。其灵活性使其非常适合存储形状变化的数据。
+
+## 2. 案例研究：GitHub事件数据
+
+### 2.1 数据集概述
+
+GitHub事件数据是一个公开可用的数据集，记录了GitHub平台上所有公开活动的时间序列。在本案例中，我们分析了存储在`gh_archive` Volume中的GitHub事件数据。
+
+**数据源细节**：
+
+* **Volume名称**：`gh_archive`
+* **文件路径**：`2025-05-14-0.json.gz`（表示2025年5月14日00:00-01:00时段的事件）
+* **文件格式**：压缩的JSON文件（使用gzip压缩）
+* **数据量**：单个文件约85.6 MB（压缩后），包含近20万条事件记录
+
+**数据结构**：
+每条记录包含以下主要字段：
+
+* `id`：事件唯一标识符
+* `type`：事件类型（如PushEvent、PullRequestEvent等）
+* `actor`：执行操作的用户信息
+* `repo`：相关的代码仓库信息
+* `org`：相关的组织信息（若适用）
+* `payload`：事件的详细信息（因事件类型而异）
+* `created_at`：事件创建时间
+* `public`：事件是否公开
+
+## 3. 通过SQL进行数据湖探索分析
+
+### 3.1 直接查询JSON文件
+
+Lakehouse数据湖平台允许直接对存储在Volume上的文件执行SQL查询，无需事先加载到表中：
+
+```sql
+-- 分析事件类型分布
+SELECT type, COUNT(*) as count 
+FROM VOLUME gh_archive
+USING json
+OPTIONS('compression'='gzip')
+FILES('2025-05-14-0.json.gz')
+GROUP BY type
+ORDER BY count DESC
+```
+
+查询结果：
+
+```
+type                         count
+----------------------------  ------
+PushEvent                     131341
+CreateEvent                   21700
+PullRequestEvent              12537
+IssueCommentEvent             7807
+WatchEvent                    7196
+DeleteEvent                   4832
+PullRequestReviewEvent        3571
+IssuesEvent                   3569
+PullRequestReviewCommentEvent 2362
+ForkEvent                     1537
+ReleaseEvent                  1261
+...
+```
+
+**特点**：
+
+* **零ETL**：无需预先提取、转换和加载数据
+* **灵活访问**：可直接访问嵌套字段
+* **即席查询**：支持即时数据探索
+
+### 3.2 处理嵌套和复杂JSON结构
+
+JSON数据常常包含嵌套对象和数组，SQL提供了直接访问这些复杂结构的能力：
+
+```sql
+-- 分析 PushEvent 提交中的文件操作类型分布
+SELECT 
+  CASE 
+    WHEN LOWER(payload.commits[0].message) LIKE '%add%' THEN 'Add'
+    WHEN LOWER(payload.commits[0].message) LIKE '%fix%' THEN 'Fix'
+    WHEN LOWER(payload.commits[0].message) LIKE '%update%' THEN 'Update'
+    WHEN LOWER(payload.commits[0].message) LIKE '%remove%' OR LOWER(payload.commits[0].message) LIKE '%delete%' THEN 'Remove'
+    WHEN LOWER(payload.commits[0].message) LIKE '%refactor%' THEN 'Refactor'
+    WHEN LOWER(payload.commits[0].message) LIKE '%deploy%' THEN 'Deploy'
+    WHEN LOWER(payload.commits[0].message) LIKE '%test%' THEN 'Test'
+    WHEN LOWER(payload.commits[0].message) LIKE '%doc%' THEN 'Documentation'
+    ELSE 'Other'
+  END as commit_type,
+  COUNT(*) as count,
+  ROUND(COUNT(*) * 100.0 / SUM(COUNT(*)) OVER (), 2) as percentage
+FROM VOLUME gh_archive
+USING json
+OPTIONS('compression'='gzip')
+FILES('2025-05-14-0.json.gz')
+WHERE type = 'PushEvent' 
+  AND payload.commits IS NOT NULL 
+  AND SIZE(payload.commits) > 0
+GROUP BY commit_type
+ORDER BY count DESC
+```
+
+查询结果：
+
+```
+commit_type    count   percentage
+------------   ------  ----------
+Other          46901   35.75

+
+### 3.3 使用JSON路径访问深层嵌套数据
+
+可以使用路径表达式深入访问JSON文档的多层嵌套结构：
+
+```sql
+-- 分析PR事件中的分支信息
+SELECT 
+  payload.pull_request.base.ref as base_branch,
+  payload.pull_request.head.ref as head_branch,
+  COUNT(*) as count
+FROM VOLUME gh_archive
+USING json
+OPTIONS('compression'='gzip')
+FILES('2025-05-14-0.json.gz')
+WHERE type = 'PullRequestEvent'
+  AND payload.action = 'opened'
+  AND payload.pull_request.base.ref IS NOT NULL
+  AND payload.pull_request.head.ref IS NOT NULL
+GROUP BY base_branch, head_branch
+ORDER BY count DESC
+LIMIT 15
+```
+
+查询结果：
+
+```
+base_branch   head_branch                                               count

+...
+```
+
+### 3.4 复杂条件过滤和正则表达式
+
+使用正则表达式和复杂条件组合过滤JSON数据：
+
+```sql
+-- 查找机器人账户创建的PR并分析目标仓库
+SELECT 
+  REGEXP_EXTRACT(actor.login, '(.*?)\\[bot\\]') as bot_name,
+  repo.name as target_repo,

+  AND payload.action = 'opened'
+  AND actor.login LIKE '%[bot]'
+GROUP BY bot_name, target_repo
+HAVING pr_count > 5
+ORDER BY pr_count DESC
+LIMIT 15
+```
+
+查询结果：
+
+```

+...
+```
+
+### 3.5 高级聚合和条件统计
+
+使用条件聚合同时分析多个指标：
+
+```sql
+-- 分析仓库活跃度：计算每个仓库的不同类型事件数量
+SELECT
+  repo.name,
+  COUNT(DISTINCT actor.id) as unique_contributors,
+  SUM(CASE WHEN type = 'PushEvent' THEN 1 ELSE 0 END) as push_count,
+  SUM(CASE WHEN type = 'PullRequestEvent' THEN 1 ELSE 0 END) as pr_count,
+  SUM(CASE WHEN type = 'IssueEvent' THEN 1 ELSE 0 END) as issue_count,
+  SUM(CASE WHEN type = 'WatchEvent' THEN 1 ELSE 0 END) as watch_count,
+  SUM(CASE WHEN type = 'ForkEvent' THEN 1 ELSE 0 END) as fork_count,
+  COUNT(*) as total_events
+FROM VOLUME gh_archive
+USING json
+OPTIONS('compression'='gzip')
+FILES('2025-05-14-0.json.gz')
+GROUP BY repo.name
+HAVING total_events > 100
+ORDER BY total_events DESC
+LIMIT 10
+```
+
+查询结果：
+
+```

+...
+```
+
+### 3.6 窗口函数分析
+
+使用窗口函数进行更复杂的排名和分组分析：
+
+```sql
+-- 窗口函数分析：计算每个组织内最活跃的用户
+SELECT
+  org_login,
+  username,
+  event_count,
+  rank_in_org
+FROM (
+  SELECT
+    org.login as org_login,
+    actor.login as username,
+    COUNT(*) as event_count,
+    RANK() OVER (PARTITION BY org.login ORDER BY COUNT(*) DESC) as rank_in_org
+  FROM VOLUME gh_archive
+  USING json
+  OPTIONS('compression'='gzip')
+  FILES('2025-05-14-0.json.gz')
+  WHERE org.login IS NOT NULL
+  GROUP BY org_login, username
+) t
+WHERE rank_in_org <= 3 AND org_login IN (
+  SELECT org.login
+  FROM VOLUME gh_archive
+  USING json
+  OPTIONS('compression'='gzip')
+  FILES('2025-05-14-0.json.gz')
+  WHERE org.login IS NOT NULL
+  GROUP BY org.login
+  ORDER BY COUNT(*) DESC
+  LIMIT 5
+)
+ORDER BY org_login, rank_in_org
+```
+
+查询结果：
+
+```
+org_login                  username                            event_count  rank_in_org

+```
+
+### 3.7 文本分析和时间处理
+
+使用字符串函数和时间函数分析JSON数据中的时间模式：
+
+```sql
+-- 验证事件类型和每小时活动的关系
+SELECT 
+  SUBSTR(created_at, 12, 2) as hour_of_day,
+  type,
+  COUNT(*) as event_count
+FROM VOLUME gh_archive
+USING json
+OPTIONS('compression'='gzip')
+FILES('2025-05-14-0.json.gz')
+GROUP BY hour_of_day, type
+ORDER BY hour_of_day, event_count DESC
+```
+
+查询结果：
+
+```
+hour_of_day  type                         event_count
+-----------  ---------------------------  -----------
+00           PushEvent                    131341
+00           CreateEvent                  21700
+00           PullRequestEvent             12537
+00           IssueCommentEvent            7807
+00           WatchEvent                   7196
+...
+```
+
+### 3.8 分析PR合并模式
+
+分析Pull Request的合并趋势：
+
+```sql
+-- 分析PR合并趋势：查看PR从创建到合并的情况
+SELECT 
+  SUBSTRING(payload.pull_request.merged_at, 1, 10) as merge_date,
+  COUNT(*) as merged_prs
+FROM VOLUME gh_archive
+USING json
+OPTIONS('compression'='gzip')
+FILES('2025-05-14-0.json.gz')
+WHERE 
+  type = 'PullRequestEvent' 
+  AND payload.action = 'closed' 
+  AND payload.pull_request.merged = true
+  AND payload.pull_request.merged_at IS NOT NULL
+GROUP BY merge_date
+ORDER BY merge_date
+```
+
+查询结果：
+
+```
+merge_date  merged_prs
+----------  ----------
+2025-05-13  3
+2025-05-14  4448
+```
+
+### 3.9 将文件数据加载到表中进行进一步分析
+
+对于需要重复分析的数据，创建表可以提高查询性能：
+
+```sql
+CREATE TABLE github_events AS
+SELECT 
+  id,
+  type,
+  actor.login as actor_name,
+  actor.id as actor_id,
+  repo.name as repo_name,
+  repo.id as repo_id,
+  org.login as org_name,
+  created_at,
+  public,
+  payload
+FROM VOLUME gh_archive
+USING json
+OPTIONS('compression'='gzip')
+FILES('2025-05-14-0.json.gz')
+```
+
+**优势**：
+* **提升性能**：表可以使用索引和缓存提高查询速度
+* **数据转换**：可在加载时应用转换和列重命名
+* **持久访问**：创建持久化视图，避免重复解析原始数据
+
+## 4. 数据湖分析的主要技术特点
+
+### 4.1 模式灵活性
+
+数据湖分析的一个核心优势是**模式灵活性**：
+
+* **模式即读取**：只有在查询时才需要定义数据结构
+* **部分字段访问**：可以只查询需要的字段，忽略其他字段
+* **进化适应**：随着数据结构的变化，查询可以轻松适应
+
+例如，在我们的GitHub事件分析中，我们可以只关注特定事件类型或特定字段，而无需处理整个数据结构。
+
+### 4.2 计算下推与过滤优化
+
+Lakehouse数据湖技术支持**计算下推**，将过滤和转换操作推送到数据源：
+
+```sql
+-- 高效的过滤查询示例
+SELECT actor.login, COUNT(*) as event_count
+FROM VOLUME gh_archive
+USING json
+OPTIONS('compression'='gzip')
+FILES('2025-05-14-0.json.gz')
+WHERE type = 'PushEvent'
+GROUP BY actor.login
+ORDER BY event_count DESC
+LIMIT 10
+```
+
+### 4.3 统一数据访问与格式选择
+
+将SQL分析应用于同一Volume中的不同类型数据文件：
+
+```sql
+-- 1. 查询JSON文件
+SELECT COUNT(*) FROM VOLUME gh_archive
+USING json
+OPTIONS('compression'='gzip')
+FILES('2025-05-14-0.json.gz');
+
+-- 2. 如果Volume中有CSV文件也可以使用类似语法查询
+-- SELECT * FROM VOLUME volume_name
+-- USING csv
+-- OPTIONS('header'='true')
+-- FILES('data.csv');
+```
+
+### 4.4 分布式处理能力
+
+数据湖分析引擎通常基于分布式计算框架，可以处理大规模数据集：
+
+* **并行处理**：自动将查询分解为并行执行的任务
+* **内存管理**：优化内存使用，处理超过单机内存容量的数据
+* **容错机制**：处理节点故障和恢复
+
+在GitHub事件分析中，即使单个文件相对较小，但同样的查询可以扩展到分析TB级的历史事件数据。
+
+## 5. 数据分析过程与方法论
+
+通过GitHub事件数据的案例，我们可以总结出一套在数据湖中分析JSON数据的方法论：
+
+### 5.1 探索性数据分析流程
+
+1. **初步预览**：获取数据样本，了解整体结构
+   ```sql
+   SELECT * FROM VOLUME gh_archive
+   USING json
+   OPTIONS('compression'='gzip')
+   FILES('2025-05-14-0.json.gz')
+   LIMIT 10
+   ```
+
+2. **概览统计**：了解数据分布和主要维度
+   ```sql
+   SELECT type, COUNT(*) as count 
+   FROM VOLUME gh_archive
+   USING json
+   OPTIONS('compression'='gzip')
+   FILES('2025-05-14-0.json.gz')
+   GROUP BY type
+   ORDER BY count DESC
+   ```
+
+3. **深入分析**：针对特定领域进行细化分析
+   ```sql
+   SELECT 
+     actor.login as username, 
+     COUNT(*) as event_count
+   FROM VOLUME gh_archive
+   USING json
+   OPTIONS('compression'='gzip')
+   FILES('2025-05-14-0.json.gz')
+   GROUP BY username
+   ORDER BY event_count DESC
+   LIMIT 15
+   ```
+
+4. **关联分析**：连接多个维度进行交叉分析
+   ```sql
+   SELECT 
+     org.login as organization,
+     type,
+     COUNT(*) as event_count
+   FROM VOLUME gh_archive
+   USING json
+   OPTIONS('compression'='gzip')
+   FILES('2025-05-14-0.json.gz')
+   WHERE org.login IS NOT NULL
+   GROUP BY organization, type
+   ORDER BY organization, event_count DESC
+   LIMIT 20
+   ```
+
+### 5.2 数据洞察方法
+
+在GitHub事件分析中，我们发现了几个关键洞察：
+
+1. **活动分布**：了解不同类型事件的占比，发现Push事件占主导（66%）
+2. **自动化趋势**：通过用户活跃度分析，发现自动化机器人账户（如github-actions\[bot]）贡献了大量活动
+3. **组织生态**：识别最活跃的组织，了解GitHub生态系统的组成
+4. **开发行为**：通过分析提交信息，了解开发者的工作方式和关注点
+5. **分支使用模式**：main和master仍然是最常见的目标分支名称
+6. **机器人活动**：dependabot、renovate和github-actions是最活跃的自动化机器人
+
+这些洞察直接来自于SQL查询，展示了SQL作为数据分析工具的强大能力。
+
+## 6. 最佳实践与优化技巧
+
+### 6.1 JSON数据分析优化
+
+* **选择性字段读取**：只选择分析所需的字段
+  ```sql
+  -- 只读取必要字段而非全部字段
+  SELECT 
+    type, 
+    actor.login, 
+    repo.name
+  FROM VOLUME gh_archive
+  USING json
+  OPTIONS('compression'='gzip')
+  FILES('2025-05-14-0.json.gz')
+  LIMIT 10
+  ```
+
+* **谓词下推**：尽早在查询中应用过滤条件
+
+* **谓词下推**：过滤条件（\`WHERE type = 'PushEvent'\`）被下推到存储层，利用列式统计信息（如最大值/最小值/布隆过滤器）跳过明显不匹配的数据块。
+* **列裁剪**：仅读取相关列（\`actor.login\`和\`type\`），跳过无关字段的解析。
+* **过滤优化**：存储层按块加载数据后，在内存中进一步过滤掉不匹配记录，最终仅保留有效数据参与计算。
+
+  ```sql
+  -- 提前过滤数据减少处理量
+  SELECT COUNT(*) 
+  FROM VOLUME gh_archive
+  USING json
+  OPTIONS('compression'='gzip')
+  FILES('2025-05-14-0.json.gz')
+  WHERE type = 'PushEvent'
+  ```
+
+* **正确处理NULL值**：使用`IS NULL`和`IS NOT NULL`检查缺失字段
+  ```sql
+  -- 识别并处理缺失数据
+  SELECT 
+    type,
+    COUNT(*) as total_count,
+    SUM(CASE WHEN org.login IS NULL THEN 1 ELSE 0 END) as without_org,
+    SUM(CASE WHEN org.login IS NOT NULL THEN 1 ELSE 0 END) as with_org
+  FROM VOLUME gh_archive
+  USING json
+  OPTIONS('compression'='gzip')
+  FILES('2025-05-14-0.json.gz')
+  GROUP BY type
+  ORDER BY total_count DESC
+  ```
+
+### 6.2 数据湖查询最佳实践
+
+1. **避免全表扫描**：尽可能使用过滤条件
+2. **合理使用聚合**：在数据量大时，优先考虑分布式聚合
+3. **选择性投影**：只选择必要的列，减少IO和内存占用
+4. **适当数据转换**：对频繁查询的数据，考虑转换为更高效的格式
+5. **利用数据分区**：基于文件名或路径进行逻辑分区
+6. **注意错误处理**：处理JSON解析错误和类型转换问题
+
+## 7. 总结
+
+通过SQL方式进行数据湖探索和分析的主要特点：
+
+1. **无需ETL**：直接查询原始数据，减少数据准备时间
+2. **灵活性**：适应半结构化数据，无需预定义模式
+3. **易用性**：使用熟悉的SQL语法，降低学习曲线
+4. **可扩展性**：处理从GB到PB级别的数据
+5. **统一访问**：同一接口处理多种数据格式
+6. **探索友好**：支持迭代式数据探索流程
+7. **性能优化**：提供多种优化技术和策略
+
+数据湖上的SQL分析结合了传统SQL的易用性和大数据处理的灵活性、可扩展性，使其成为现代数据分析的强大工具。通过本文的GitHub事件数据分析案例，我们展示了如何使用SQL直接查询和分析存储在数据湖Volume上的JSON文件，从而快速获取有价值的数据洞察。

+# 探索和分析数据湖Volume上的Parquet文件里的数据
+
+## 引言
+
+数据湖是Lakehouse的重要组成部分，允许您以原始格式存储所有结构化和非结构化数据，无需事先定义模式，这充分体现了湖仓一体的优势，将Lakehouse的数据管理扩展到对非结构化数据的一体化管理，不再局限于数仓里的结构化数据管理。本文将介绍如何利用SQL在Lakehouse环境中探索和分析存储在Volume上的Parquet文件数据，以纽约市出租车数据分析为实例，展示数据探索的完整过程和方法。
+
+## Parquet格式简介
+
+Parquet是一种列式存储格式，专为大数据处理而设计，具有以下主要特点：
+
+* **列式存储**：数据按列而非按行存储，特别适合于分析查询
+* **高效压缩**：相比传统行式存储如CSV，可节省50-75%的存储空间
+* **高性能**：支持谓词下推(predicate pushdown)，允许查询引擎仅读取需要的列和行
+* **自包含元数据**：文件包含模式定义，支持自描述
+* **广泛兼容**：被Hadoop、Spark、Presto等大数据工具广泛支持
+
+Parquet格式特别适合存储和查询大规模的结构化数据，如日志数据、事务数据和传感器数据，非常适合数据湖场景。
+
+## 数据湖Volume概念
+
+在Lakehouse平台中，Volume是一个关键概念：
+
+* **Volume**是数据湖中的逻辑存储单元，类似于传统数据库中的表空间
+* Volume可以指向内部存储或外部存储(如OSS、S3、HDFS等)
+* 通过Volume机制，数据湖可以直接查询外部存储系统中的数据，无需导入
+* 每个Volume可以包含多个文件，支持目录层次结构
+
+本文以`yellow_trip_record_data`为例，这是一个指向外部对象存储的Volume，包含纽约市黄色出租车的行程数据。
+
+## 样例数据介绍
+
+本文使用的纽约市出租车数据(NYC Yellow Taxi Trip Records)是一个公开的交通数据集：

+
+## 1. 数据湖Volume基础操作
+
+在开始分析前，需要了解和掌握数据湖Volume的基础操作，这是与数据交互的第一步。
+
+### 1.1 列出可用Volume
+
+```sql
+SHOW VOLUMES;
+```
+
+通过此命令可以查看所有可用的数据卷，包括Volume名称、创建时间、类型(内部/外部)、URL地址等信息。在我们的示例中，这个命令会显示包括`yellow_trip_record_data`在内的所有可用Volume。
+
+执行结果示例：
+
+```
+volume_name: yellow_trip_record_data
+create_time: 2025-05-14T06:40:56.571000+00:00
+external: true
+workspace_name: ns227206
+url: oss://tlc-trip-record-data/yellow-trip-record-data/
+recursive_file_lookup: true
+connection: ns227206.oss_sh_conn_ak
+```
+
+从结果可以看出，这是一个外部Volume，指向OSS对象存储中的一个路径，并且启用了递归文件查找选项。
+
+### 1.2 列出Volume中的文件
+
+```sql
+LIST VOLUME yellow_trip_record_data SUBDIRECTORY '/';
+```
+
+此命令将显示指定Volume根目录中的所有文件，包括文件相对路径、完整URL、文件大小和最后修改时间等信息。`SUBDIRECTORY '/'`表示查看根目录下的文件，如果数据有层次结构，可以指定子目录路径。
+
+执行结果示例：
+
+```
+relative_path: yellow_tripdata_2024-01.parquet
+url: oss://tlc-trip-record-data/yellow-trip-record-data/yellow_tripdata_2024-01.parquet
+size: 49961641
+last_modified_time: 2025-05-14T12:02:21+00:00
+
+relative_path: yellow_tripdata_2024-02.parquet
+...
+```
+
+此结果显示Volume中包含多个按月命名的Parquet文件，每个约50MB大小，包含2024年1月至2025年2月的数据。
+
+## 2. 初步数据探索
+
+在处理不熟悉的数据集时，首先需要了解数据的整体情况，建立对数据内容和结构的初步认识。
+
+### 2.1 列出文件
+
+对于我们的示例数据集，首先列出所有可用的数据文件：
+
+```sql
+LIST VOLUME yellow_trip_record_data SUBDIRECTORY '/';
+```
+
+执行该命令后，我们看到Volume中包含多个Parquet文件，命名模式为`yellow_tripdata_YYYY-MM.parquet`。
+
+### 2.2 了解文件格式和命名规则
+
+通过观察文件名(如`yellow_tripdata_2024-01.parquet`)，我们可以了解到:
+
+* 文件格式为Parquet（通过.parquet后缀识别）
+* 命名规则为"yellow\_tripdata\_年份-月份.parquet"
+* 数据按月份组织，覆盖2024年1月至2025年2月
+* 每个文件大小约为50-60MB
+
+这种命名和组织方式是数据湖中常见的分区策略，按时间维度分割数据，方便查询特定时间段的数据并提高查询效率。
+
+### 2.3 了解数据来源和背景
+
+纽约出租车与豪华轿车委员会(TLC)收集的黄色出租车行程记录数据包含出租车行程的上下车日期/时间、位置、行程距离、详细费用、费率类型、付款方式等信息。此类公共交通数据对城市规划、交通管理和商业决策具有重要价值。
+
+## 3. 数据预览
+
+在深入分析前，先预览数据结构和内容至关重要，这样可以了解数据的质量、格式和可能的分析方向。
+
+### 3.1 预览Parquet文件内容
+
+Clickzetta允许我们直接使用SQL查询来预览Parquet文件的内容，无需先创建表或导入数据：
+
+```sql
+SELECT * FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet')
+LIMIT 10;
+```
+
+这个查询语法的关键部分：
+
+* `FROM VOLUME yellow_trip_record_data`：指定数据来源是哪个Volume
+* `USING parquet`：声明文件格式为Parquet
+* `FILES('yellow_tripdata_2024-01.parquet')`：指定要查询的具体文件
+* `LIMIT 10`：只返回前10条记录，用于快速预览
+
+执行结果示例：
+
+```
+VendorID: 2
+tpep_pickup_datetime: 2024-01-01T00:57:55
+tpep_dropoff_datetime: 2024-01-01T01:17:43
+passenger_count: 1
+trip_distance: 1.72
+RatecodeID: 1
+store_and_fwd_flag: N
+PULocationID: 186
+DOLocationID: 79
+payment_type: 2
+fare_amount: 17.7
+extra: 1.0
+mta_tax: 0.5
+tip_amount: 0.0
+tolls_amount: 0.0
+improvement_surcharge: 1.0
+total_amount: 22.7
+congestion_surcharge: 2.5
+Airport_fee: 0.0
+...
+```
+
+### 3.2 分析数据结构
+

+| DOLocationID            | 整数   | 下车地点ID（对应纽约市区域编码）                                       |
+| payment\_type           | 整数   | 支付方式编码 (1=信用卡, 2=现金, 3=免费, 4=纠纷, 5=未知)                  |
+| fare\_amount            | 浮点数  | 行程基本费用                                                  |
+| total\_amount           | 浮点数  | 包含所有费用的总金额                                              |
+
+通过这种初步检查，我们现在了解了数据的结构和字段含义，为后续的分析奠定了基础。
+
+## 4. 基础数据分析
+
+获取数据基本概况，包括数量统计、平均值和异常值检测。
+
+### 4.1 基础统计分析
+
+```sql
+SELECT 
+  COUNT(*) as total_trips,
+  AVG(trip_distance) as avg_distance,
+  MIN(trip_distance) as min_distance,
+  MAX(trip_distance) as max_distance,
+  AVG(total_amount) as avg_fare,
+  MIN(total_amount) as min_fare,
+  MAX(total_amount) as max_fare,
+  AVG(TIMESTAMPDIFF(MINUTE, tpep_pickup_datetime, tpep_dropoff_datetime)) as avg_trip_duration_minutes
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet');
+```
+
+### 4.2 分类分析
+
+分析分类变量(如支付方式)的分布情况:
+
+```sql
+SELECT 
+  payment_type,
+  COUNT(*) as trip_count,
+  ROUND(COUNT(*) * 100.0 / (SELECT COUNT(*) FROM VOLUME yellow_trip_record_data USING parquet FILES('yellow_tripdata_2024-01.parquet')), 2) as percentage
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet')
+GROUP BY payment_type
+ORDER BY trip_count DESC;
+```
+
+### 4.4 热点区域分析
+
+```sql
+-- 最热门的上车地点
+SELECT 
+  PULocationID,
+  COUNT(*) as pickup_count,
+  ROUND(AVG(trip_distance), 2) as avg_distance,
+  ROUND(AVG(total_amount), 2) as avg_fare
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet')
+GROUP BY PULocationID
+ORDER BY pickup_count DESC
+LIMIT 5;
+```
+
+**执行结果**：
+
+```
+| PULocationID | pickup_count | avg_distance | avg_fare |
+|--------------|--------------|--------------|----------|
+| 132          | 145240       | 15.49        | 76.58    |
+| 161          | 143471       | 2.56         | 23.48    |
+| 237          | 142708       | 1.70         | 19.45    |
+| 236          | 136465       | 1.85         | 20.00    |
+| 162          | 106717       | 2.23         | 22.88    |
+```
+
+该查询揭示了最受欢迎的上车点：
+
+* PULocationID 132是最热门的上车点，有145,240次乘车
+* 该区域平均行程距离显著高于其他区域（15.49英里），平均费用也最高（76.58美元），这表明它可能是一个主要机场或交通枢纽
+* 其他热门上车点（如161、237、236和162）的平均行程距离和费用明显低于132，可能是市区热门位置
+
+### 4.5 数值分布分析
+
+```sql
+-- 行程距离与价格的分布
+SELECT 
+  CASE 
+    WHEN trip_distance BETWEEN 0 AND 1 THEN '0-1'
+    WHEN trip_distance BETWEEN 1 AND 2 THEN '1-2'
+    WHEN trip_distance BETWEEN 2 AND 3 THEN '2-3'
+    WHEN trip_distance BETWEEN 3 AND 5 THEN '3-5'
+    WHEN trip_distance BETWEEN 5 AND 10 THEN '5-10'
+    ELSE '10+'
+  END AS distance_range,
+  COUNT(*) as trip_count,
+  ROUND(AVG(total_amount), 2) as avg_fare
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet')
+WHERE trip_distance <= 100 -- 过滤掉异常值
+GROUP BY distance_range
+ORDER BY CASE 
+    WHEN distance_range = '0-1' THEN 1
+    WHEN distance_range = '1-2' THEN 2
+    WHEN distance_range = '2-3' THEN 3
+    WHEN distance_range = '3-5' THEN 4
+    WHEN distance_range = '5-10' THEN 5
+    ELSE 6
+  END;
+```
+
+**执行结果**：
+
+```
+| distance_range | trip_count | avg_fare |
+|----------------|------------|----------|
+| 0-1            | 778076     | 15.00    |
+| 1-2            | 967440     | 18.37    |
+| 2-3            | 448775     | 23.83    |
+| 3-5            | 308574     | 30.39    |
+| 5-10           | 233505     | 46.68    |
+| 10+            | 228195     | 83.41    |
+```
+
+这个分析提供了行程距离和费用之间关系的重要见解：
+
+* 1-2英里是最常见的行程距离范围，有967,440次行程
+* 短距离行程（0-3英里）占总行程的73.7%
+* 行程距离与平均费用呈明显的正相关关系
+* 10英里以上的长途行程均价高达83.41美元，是短途行程（0-1英里）均价的5.5倍
+
+```sql
+SELECT 
+  CASE 
+    WHEN trip_distance BETWEEN 0 AND 1 THEN '0-1'
+    WHEN trip_distance BETWEEN 1 AND 2 THEN '1-2'
+    WHEN trip_distance BETWEEN 2 AND 3 THEN '2-3'
+    WHEN trip_distance BETWEEN 3 AND 5 THEN '3-5'
+    WHEN trip_distance BETWEEN 5 AND 10 THEN '5-10'
+    WHEN trip_distance BETWEEN 10 AND 20 THEN '10-20'
+    WHEN trip_distance > 20 THEN '20+'
+    ELSE 'Unknown'
+  END AS distance_range,
+  COUNT(*) as trip_count,
+  ROUND(AVG(total_amount), 2) as avg_fare
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet')
+WHERE trip_distance <= 100 -- 过滤掉异常值
+GROUP BY distance_range
+ORDER BY CASE 
+    WHEN distance_range = '0-1' THEN 1
+    WHEN distance_range = '1-2' THEN 2
+    WHEN distance_range = '2-3' THEN 3
+    WHEN distance_range = '3-5' THEN 4
+    WHEN distance_range = '5-10' THEN 5
+    WHEN distance_range = '10-20' THEN 6
+    WHEN distance_range = '20+' THEN 7
+    ELSE 8
+  END;
+```
+
+## 5. 高级分析和聚合
+
+更深入的数据分析，包括多维度聚合、热点分析等。
+
+### 5.1 时间维度聚合
+
+```sql
+-- 每小时行程分布
+SELECT 
+  HOUR(tpep_pickup_datetime) as hour_of_day,
+  COUNT(*) as trip_count,
+  ROUND(AVG(trip_distance), 2) as avg_distance,
+  ROUND(AVG(total_amount), 2) as avg_fare
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet')
+GROUP BY hour_of_day
+ORDER BY hour_of_day ASC;
+```
+
+### 5.2 热点区域分析
+
+```sql
+-- 最热门的上车地点
+SELECT 
+  PULocationID,
+  COUNT(*) as pickup_count,
+  ROUND(AVG(trip_distance), 2) as avg_distance,
+  ROUND(AVG(total_amount), 2) as avg_fare
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet')
+GROUP BY PULocationID
+ORDER BY pickup_count DESC
+LIMIT 10;
+```
+
+### 5.3 多维度对比分析
+
+```sql
+-- 工作日vs周末的行程情况
+SELECT 
+  CASE 
+    WHEN DAYOFWEEK(tpep_pickup_datetime) IN (1, 7) THEN '周末'
+    ELSE '工作日'
+  END AS day_type,
+  COUNT(*) as trip_count,
+  ROUND(AVG(trip_distance), 2) as avg_distance,
+  ROUND(AVG(total_amount), 2) as avg_fare,
+  ROUND(AVG(passenger_count), 2) as avg_passengers
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet')
+WHERE trip_distance <= 100 -- 过滤掉异常值
+GROUP BY day_type;
+```
+
+## 6. 时间序列分析
+
+分析多个时间段的数据变化趋势。
+
+### 6.1 多月份数据合并分析
+
+由于无法直接通过文件名变量引用多个文件，可以使用以下方法处理多月份数据:
+
+```sql
+-- 使用CTE合并多月数据
+WITH jan AS (
+  SELECT 
+    '2024-01' as month,
+    COUNT(*) as trip_count,
+    ROUND(AVG(trip_distance), 2) as avg_distance,
+    ROUND(AVG(total_amount), 2) as avg_fare
+  FROM VOLUME yellow_trip_record_data
+  USING parquet
+  FILES('yellow_tripdata_2024-01.parquet')
+  WHERE trip_distance <= 100
+),
+feb AS (
+  SELECT 
+    '2024-02' as month,
+    COUNT(*) as trip_count,
+    ROUND(AVG(trip_distance), 2) as avg_distance,
+    ROUND(AVG(total_amount), 2) as avg_fare
+  FROM VOLUME yellow_trip_record_data
+  USING parquet
+  FILES('yellow_tripdata_2024-02.parquet')
+  WHERE trip_distance <= 100
+)
+SELECT * FROM jan
+UNION ALL SELECT * FROM feb
+ORDER BY month;
+```
+
+### 6.2 季度数据分析
+
+```sql
+-- 分析各季度支付方式趋势
+WITH q1 AS (
+  SELECT 
+    '2024-Q1' as quarter,
+    payment_type,
+    COUNT(*) as payment_count
+  FROM VOLUME yellow_trip_record_data
+  USING parquet
+  FILES('yellow_tripdata_2024-01.parquet', 'yellow_tripdata_2024-02.parquet', 'yellow_tripdata_2024-03.parquet')
+  GROUP BY quarter, payment_type
+),
+q2 AS (
+  SELECT 
+    '2024-Q2' as quarter,
+    payment_type,
+    COUNT(*) as payment_count
+  FROM VOLUME yellow_trip_record_data
+  USING parquet
+  FILES('yellow_tripdata_2024-04.parquet', 'yellow_tripdata_2024-05.parquet', 'yellow_tripdata_2024-06.parquet')
+  GROUP BY quarter, payment_type
+)
+SELECT * FROM q1
+UNION ALL SELECT * FROM q2
+ORDER BY quarter, payment_type;
+```
+
+## 7. 最佳实践和优化技巧
+
+### 7.1 数据过滤
+
+在处理大数据时，合理的过滤条件可以大幅提高查询效率:
+
+```sql
+-- 使用WHERE子句过滤异常值
+SELECT 
+  COUNT(*) as trip_count,
+  ROUND(AVG(trip_distance), 2) as avg_distance
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet')
+WHERE 
+  trip_distance BETWEEN 0.5 AND 100 AND  -- 排除可能的异常距离
+  total_amount > 0 AND                   -- 排除免费或错误记录的行程
+  passenger_count > 0;                   -- 排除无乘客记录
+```
+
+有效的过滤条件能够：
+
+* 排除数据异常值，提高分析结果的准确性
+* 减少处理的数据量，提高查询性能
+* 专注于最相关的数据子集，满足特定的分析需求
+
+### 7.2 列剪裁和谓词下推
+
+充分利用Parquet格式的列式存储和谓词下推特性：
+
+```sql
+-- 只选择需要的列而非所有列
+SELECT 
+  tpep_pickup_datetime,
+  tpep_dropoff_datetime,
+  trip_distance,
+  total_amount
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet')
+WHERE HOUR(tpep_pickup_datetime) BETWEEN 8 AND 10  -- 利用谓词下推只读取需要的行
+LIMIT 1000;
+```
+
+这种优化策略能够：
+
+* 减少I/O量，仅读取查询所需的列数据
+* 利用Parquet内置的过滤能力，在文件里跳过不符合条件的数据块
+* 显著提高大数据集上的查询性能
+
+### 7.3 分阶段分析
+
+对于大型数据集，采用分阶段分析策略:
+
+1. 先在单个文件上进行探索性分析
+2. 验证分析逻辑后再扩展到全部数据
+3. 使用CTE组织复杂查询，增强可读性和可维护性
+
+```sql
+-- 使用CTE简化复杂查询
+WITH hourly_stats AS (
+  SELECT 
+    HOUR(tpep_pickup_datetime) as hour_of_day,
+    COUNT(*) as trip_count,
+    AVG(trip_distance) as avg_distance
+  FROM VOLUME yellow_trip_record_data
+  USING parquet
+  FILES('yellow_tripdata_2024-01.parquet')
+  GROUP BY HOUR(tpep_pickup_datetime)
+),
+peak_hours AS (
+  SELECT 
+    hour_of_day,
+    trip_count,
+    avg_distance,
+    RANK() OVER (ORDER BY trip_count DESC) as popularity_rank
+  FROM hourly_stats
+)
+SELECT * FROM peak_hours
+WHERE popularity_rank <= 5
+ORDER BY popularity_rank;
+```
+
+这种方法使得复杂查询更易于理解、调试和维护。
+
+### 7.4 数据质量检查
+
+在分析前进行数据质量检查:
+
+```sql
+-- 检查缺失值和异常值
+SELECT 
+  COUNT(*) as total_records,
+  SUM(CASE WHEN passenger_count IS NULL OR passenger_count = 0 THEN 1 ELSE 0 END) as missing_passenger_count,
+  SUM(CASE WHEN trip_distance IS NULL OR trip_distance = 0 THEN 1 ELSE 0 END) as zero_distance,
+  SUM(CASE WHEN trip_distance > 100 THEN 1 ELSE 0 END) as suspicious_long_trips,
+  SUM(CASE WHEN total_amount < 0 THEN 1 ELSE 0 END) as negative_fares
+FROM VOLUME yellow_trip_record_data
+USING parquet
+FILES('yellow_tripdata_2024-01.parquet');
+```
+
+数据质量检查能够：
+
+* 发现数据中的问题和异常
+* 指导后续分析中的数据清理和转换
+* 提高分析结果的可靠性和准确性
+
+## 结论
+
+通过SQL方式直接分析数据湖Volume中的Parquet文件，我们可以:
+
+1. 快速探索和了解数据结构
+2. 进行全方位的统计分析
+3. 发现数据中的时间和空间模式
+4. 比较不同时间段的数据变化趋势
+
+这种方法避免了数据复制和转换的开销，直接在数据湖上进行分析，提高了效率。对于大数据环境，这种分析方式既灵活又高效，特别适合数据科学家和分析师进行数据探索和初步分析。
+
+通过本文的纽约出租车数据案例，我们展示了从基础的数据探索到复杂的时间序列分析的完整流程，为数据湖环境下的Parquet文件分析提供了实用指南。与传统的先导入后分析的方法相比，这种直接查询方法极大地提高了数据分析的灵活性和响应速度，特别适合于初步数据探索和验证分析假设。
+
+在实际项目中，这些分析可以为出租车公司优化车辆调度、城市管理部门改善交通规划、金融分析师了解消费趋势等多种场景提供数据支持。数据湖上的SQL分析正成为连接原始数据和商业洞察的关键桥梁。

+## 语法格式
+
+```SQL
+DROP DYNAMIC TABLE [IF EXISTS] dtname;
+```
+
+* `IF EXISTS`：可选参数，用于在删除动态表时避免因表不存在而导致的错误。如果指定了`IF EXISTS`，当尝试删除一个不存在的动态表时，系统不会报错。
+
+## 使用示例
+
+1. 删除名为`change_table_dy`的动态表：
+
+   ```SQL
+   DROP DYNAMIC TABLE IF EXISTS change_table_dy;
+   ```
+
+2. 删除名为`employee_dy`的动态表，但不检查表是否存在（使用 IF EXISTS 参数）：
+
+   ```SQL
+   DROP DYNAMIC TABLE employee_dy;
+   ```
+
+3. 删除名为`sales_dy`的动态表，如果该表不存在，则不报错：
+
+   ```SQL
+   DROP DYNAMIC TABLE IF EXISTS sales_dy;
+   ```
+
+## 注意事项
+
+* 在执行删除动态表操作之前，请确保您已对表中的数据进行了备份，以防止数据丢失。
+* 删除动态表操作是不可逆的，一旦执行，表及其数据将永久丢失。
+* 在删除动态表时，请确保没有其他用户或进程正在访问该表。如有需要，您可以先暂停相关操作，再执行删除操作。
+
+## 相关命令
+
+* [CREATE DYNAMIC TABLE](create-dynamic-table.md)：创建动态表。
+* [ALTER DYNAMIC TABLE](alter-dynamic-table.md)：修改动态表结构。

+# Lakehouse 列级安全（动态脱敏）使用文档
+> 【预览发布】本功能当前处于受邀预览发布阶段。如需使用，请联系我们的技术支持团队协助处理。
+## 1. 概述
+
+列级安全（Column-level Security）通过动态脱敏（Dynamic Data Masking）提供细粒度数据保护能力，可根据用户身份或角色动态修改敏感数据的显示方式（如部分隐藏、替换字符）。系统仅存储原始数据，在数据读取运行时才执行脱敏函数（mask function）。本文档介绍如何通过 SQL 接口实现此功能。
+
+## 2. 核心语法
+
+### 2.1 创建脱敏策略函数
+
+参考[CREATE FUNCTION(SQL)](create-sql-function.md)语法
+
+```sql
+CREATE  FUNCTION [schema_name.]function_name (col_name column_type) 
+RETURNS output_type 
+AS 
+expression_with_conditional_logic;
+```
+
+**关键要素**：
+
+* 必须返回与原始列相同的数据类型
+* 使用安全上下文函数：
+  * `current_user()` 获取当前用户（注意大小写）
+  * `current_roles()` 获取用户角色数组
+
+### 2.2 绑定策略到列
+
+**创建表时指定**：
+
+```sql
+CREATE TABLE table_name (
+  col1 STRING MASK schema_name.masking_function,
+  ...
+);
+```
+
+**修改已有表**：
+
+```sql
+ALTER TABLE table_name 
+CHANGE COLUMN column_name 
+SET MASK schema_name.masking_function;
+```
+
+**添加列时指定脱敏**：
+
+```SQL
+ALTER TABLE table_nameADD COLUMN (column_name column_typeMASK schema_name.masking_function);
+```
+
+### 2.3 解除策略绑定
+
+```sql
+ALTER TABLE table_name 
+CHANGE COLUMN column_name 
+UNSET MASK;
+```
+
+***
+
+## 3. 使用场景示例
+
+### 3.1 基础脱敏
+
+**需求**：身份证号前6位+4星号+后4位
+
+```sql
+CREATE FUNCTION public.idcard_masking(idcard STRING)
+RETURNS STRING
+AS concat(substr(idcard, 1, 6), repeat('*', 4), substr(idcard, 10, 4));
+
+ALTER TABLE data CHANGE COLUMN idcard SET MASK public.idcard_masking;
+```
+
+**查询效果**：
+
+```
+原始值：130183199901011234 → 脱敏后：130183****9010
+```
+
+### 3.2 基于用户的动态脱敏
+
+**需求**： 仅UAT\_TEST用户看到脱敏数据
+
+```sql
+CREATE FUNCTION public.idcard_masking(idcard STRING)
+RETURNS STRING
+AS 
+CASE 
+  WHEN current_user() = "UAT_TEST" 
+  THEN concat(substr(idcard, 1, 6), repeat('*', 4), substr(idcard, 10, 4))
+  ELSE idcard 
+END;
+--忽略用户名大小写
+CREATE FUNCTION public.idcard_masking(idcard STRING)
+RETURNS STRING
+AS 
+CASE 
+  WHEN lower(current_user()) = "uat_test" 
+  THEN concat(substr(idcard, 1, 6), repeat('*', 4), substr(idcard, 10, 4))
+  ELSE idcard 
+END;
+```
+
+### 3.3 基于角色的动态脱敏
+
+**需求**： user\_admin角色可查看完整信息
+
+```sql
+CREATE FUNCTION public.idcard_masking_role(idcard STRING)
+RETURNS STRING
+AS 
+CASE 
+  WHEN array_contains(current_roles(), "user_admin") 
+  THEN idcard
+  ELSE concat(substr(idcard,1,6), '****', substr(idcard,11,4)) 
+END;
+```
+
+***
+
+## 4. 完整操作示例
+
+### 4.1 初始化环境
+
+```sql
+CREATE SCHEMA IF NOT EXISTS security_demo;
+USE security_demo;
+-- 通用掩码函数
+CREATE FUNCTION security_demo.ssn_mask(ssn STRING)
+RETURNS STRING
+AS concat('***-**-', substr(ssn, 8, 4));
+
+CREATE TABLE security_demo.user_data (
+  name STRING,
+  ssn STRING MASK security_demo.ssn_mask,  -- 建表时直接绑定
+  phone STRING
+);
+INSERT INTO security_demo.user_data VALUES('James', '123-45-6789','123456789');
+SELECT * FROM      security_demo.user_data;
+```
+
+### 4.2 创建策略函数
+
+```sql
+-- 特权角色豁免
+CREATE FUNCTION security_demo.admin_ssn_mask(ssn STRING)
+RETURNS STRING
+AS 
+CASE
+  WHEN array_contains(current_roles(), 'user_admin') THEN ssn
+  ELSE concat('***-**-', substr(ssn,8,4))
+END;
+```
+
+### 4.3 修改脱敏策略
+
+```sql
+--去除之前的策略
+ALTER TABLE security_demo.user_data CHANGE COLUMN ssn UNSET MASK;
+
+--添加新的策略
+ALTER TABLE security_demo.user_data CHANGE COLUMN ssn SET MASK security_demo.admin_ssn_mask;
+```
+
+### 4.4 验证效果
+
+**普通用户查询**：
+
+```sql
+SELECT * FROM user_data;
+-- 输出：John Doe ***-**-6789 138****1234
+```
+
+**USER\_ADMIN角色查询**：
+
+```sql
+SELECT * FROM user_data; 
+-- 输出：John Doe 123-45-6789 138****1234
+```
+
+***
+
+## 5. 管理注意事项
+
+### 5.1 权限控制
+
+* 仅允许具有 `ALTER TABLE` 权限的角色修改脱敏策略。
+* 函数创建需要 `CREATE FUNCTION` 权限。
+
+### 5.2 性能建议
+
+* 避免在脱敏函数中使用复杂计算。
+* 对高频查询列，谨慎使用条件判断逻辑。
+
+## 6. 限制说明
+
+* 单个列只能绑定一个脱敏策略。如果您想定义多种脱敏规则，可以在一个函数中基于条件判断实现不同的策略。

+# 使用Explain查看动态表刷新模式
+
+通过 explain 命令查看是否能增量刷新（preview），需要通过开关开启，开启的开关为 `set cz.optimizer.explain.can.incrementalize=true;` 在数据开发中需要选中一起执行。
+
+**语法**
+
+```Plain
+set cz.optimizer.explain.can.incrementalize=true;
+EXPLAIN REFRESH DYNAMIC TABLE dtname;
+```
+
+使用说明
+
+* `explain` 命令通常是用来查看 SQL 执行计划。刷新动态表时添加 `explain` 可以用来查看动态表的执行计划，同时 Lakehouse 会输出是否是增量计划字段 `CanBeIncrementalized`。如果为 `Yes` 表示执行的是增量计划。如果输出为 `No` 表示不是增量计划，并会给出原因（No because ...）。
+
+**具体案例**
+
+```SQL
+set cz.optimizer.explain.can.incrementalize=true;
+explain refresh dynamic table event_gettime;
+```
+
+![](.topwrite/assets/image_1720597444254.png)
+
+# 使用Show命令查看动态表刷新模式
+通过 `show dynamic table refresh history` 查看。输出的字段中，`refresh_mode` 可以查看是否是增量刷新，`stats` 字段记录了增量刷新的条数。
+
+
+**语法**
+
+```SQL
+ SHOW DYNAMIC TABLE REFRESH HISTORY [where <expr>] [LIMIT num];
+```
+
+**参数说明**
+
+* `WHERE <expr>`:WHERE \<expr>:(可选)支持用户根据`SHOW JOBS`命令显示的字段进行筛选。用户可以通过表达式对结果进行过滤，以便更精确地查找所需的数据。
+* `LIMIT num`：（可选）限制返回的作业记录数量，范围为1-10000。

+# 动态表简介
+【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请联系我们的技术支持同学协助处理。
+
+## 什么是动态表
+
+动态表（Dynamic Table）是云器Lakehouse的数据对象。创建时与表的区别是通过定义查询语句动态生成数据，刷新时自动获取Base Table的增量数据，采用增量算法进行计算，这样做的优势是大幅提升数据处理效率，尤其适用于处理大规模数据。
+
+## 动态表应用场景
+
+### 面向实时加工场景
+
+在实时数据加工场景中，数据以持续且快速的方式流入系统。传统的数据处理方法，如完全重载（Full Reload）或全量刷新（Full Refresh），在性能和资源消耗方面可能不够高效，特别是在处理大规模数据流时。动态表采用增量计算方法，仅处理自上次更新以来变化的数据，从而显著减少了计算资源的消耗。
+
+**动态表的优势**：
+
+* **实时性**：能够迅速将新数据变更反映到数据仓库中，保持数据的高新鲜度。
+* **成本效益**：通过设置合理的刷新间隔，可以平衡性能与成本，实现资源的最优利用。
+* **资源弹性**：Lakehouse的资源可以轻松实现弹性扩展，尤其在处理峰值数据流入时更具优势。
+* **按需计算**：未来Lakehouse将实现按需启动计算资源，即仅在有数据需要计算时才会启动相应资源，进一步提高效率和降低成本。
+
+**应用实例**：
+
+**背景**： 一家电子商务公司希望实时分析其销售数据，以便快速做出库存和定价决策。数据以高速率持续流入系统，需要一种高效的数据处理方法。
+
+**挑战**：
+
+* 传统的全量数据处理方法在性能和资源消耗方面效率低下，尤其是在高峰时段。
+* 需要一种能够快速响应数据变更并保持数据新鲜的处理机制。
+
+**解决方案**：
+
+* 引入动态表，采用增量计算方法，仅处理自上次更新以来变化的数据。
+
+**动态表的优势**：
+
+1. **实时性**： 动态表能够迅速捕捉并反映数据变更，确保决策基于最新的销售数据。
+
+2. **成本效益**：通过动态表，公司可以根据实际需求设置合理的数据刷新间隔，避免了不必要的计算资源浪费。
+
+3. **资源弹性**：在促销活动或节假日等流量高峰时段，Lakehouse的资源可以按需扩展，以应对数据流入的峰值，而不必长期维持高额的资源配置。
+
+4. **按需计算**：未来，Lakehouse的按需计算功能将进一步提高效率，仅在有数据需要计算时才启动资源，从而降低成本。
+
+### 数据新鲜度要求较高的**固定维度分析查询场景**
+
+在固定维度分析查询场景中，我们追求的是能够提供近乎实时的分析结果。传统的视图查询可以实现这一点，但如果涉及大量数据转换，则可能会导致查询速度变慢。为了解决这个问题，我们可以将转换后的结果进行物化，这样在查询时就可以直接返回这些结果，从而提高查询速度。物化结果可以采用传统的表格或者dynamic table。
+
+使用传统的表可以提供最高的性能，因为它们在查询时只返回预先转换好的数据。但这种方法的缺点是，需要定期评估数据转换的时间，并通过调度进行全量计算，这通常会占用较长的时间。
+
+dynamic table结合了增量计算的优势。通过仅更新自上次加载以来发生变化的记录，dynamic table不仅减少了每次构建的时间，通过缩短时间间隔还保持了数据的最新性。
+
+### 注意事项
+
+* 在处理源端大量变化数据时，计算任务可能接近全量计算的负载。尽管增量计算在效率上具有明显优势，但如果您设置的刷新间隔过短，可能会导致任务积压。这是因为每次刷新操作本身需要一定的时间来完成，如果这个时间超过了您设置的刷新间隔，将会导致后续刷新任务的排队等待。
+  * **建议**：
+    * **合理设置刷新间隔**：根据数据变更的频率和任务的刷新耗时，合理设置刷新间隔，以避免刷新操作的积压。
+    * **监控和调整**：持续监控数据变更模式和系统性能，根据实际情况调整刷新间隔，以实现效率和资源的最优化利用。
+* 在编写算子时，请参考《算子是如何增量刷新》中的注意事项来优化增量刷新任务。
+
+## 动态表工作原理概述
+
+### 如何获取变化的数据
+
+* MetaService（元数据服务，Lakehouse 的一个组件服务）记录了 Lakehouse 里每张表的每一个历史数据版本

+  * 基本概念：一张表的 **Snapshot（全量）** VS **Delta（变化）**
+
+
+## **Lakehouse Dynamic Table 刷新机制**
+
+Lakehouse 目前使用调度机制来更新 Dynamic Table。支持以下几种调度模式：
+
+1. **在 DDL 语句中定义调度属性**
+2. **在 Lakehouse Studio 中定义调度**
+3. **使用第三方调度引擎提交 Refresh 作业**
+
+|                          | 使用方式                                                                                                    | 优点                                                        | 缺点                                                                                    |
+| ------------------------ | ------------------------------------------------------------------------------------------------------- | --------------------------------------------------------- | ------------------------------------------------------------------------------------- |
+| DDL语句中定义调度属性             | 在refreshOption中定义刷新间隔，具体使用方式[参考动态表创建文档](<create-dynamic-table.md>)。目前限制刷新间隔一分钟。 | 简单易用，可以快速设置刷新选项。不依赖任何第三方工具。                               | 当前Lakehouse不支持在 Dynamic Table 上定义严格的上下游依赖关系。在 DDL 定义中依赖时间调度。可以通过时间间隔的方式先保证上游刷新完成再调度下游 |
+| 在 Lakehouse Studio 中定义调度 | 可以在 Lakehouse Studio 中通过可视化界面配置调度，具体配置方式可以参考[任务开发调度文档](taskdevelop.md)。目前限制刷新间隔一分钟。                     | 可视化配置，用户友好。支持调度依赖配置，确保上游刷新完成后再刷新下游。支持单节点运行监控，如失败告警、超时告警等。 |                                                                                       |
+| 使用第三方调度引擎提交 Refresh 作业   | 通过下载 Lakehouse 客户端命令，使用 cron 表达式定时提交 Refresh 任务。或者通过 Java Jdbc 接口自定义提交 Refresh 命令。                      | 您可以更灵活地控制作业的提交和配置调度信息，时间间隔没有限制                            | 需要依赖第三方调度。引入第三方调度系统                                                                   |
+
+## 动态表和物化视图、普通视图的比较
+
+从Lakehouse的实现机制上来看，动态表是基于传统的物化视图来演进的，虽然两者有一些共性，但是定位上存在很大区别
+
+|       | 物化视图                                        | 动态表                         | 普通视图                                              |
+| ----- | ------------------------------------------- | --------------------------- | ------------------------------------------------- |
+| 定义    | 一种预计算并存储查询结果的特殊视图                           | 专注于数据加工的高效工具                | 一种虚拟表，不存储数据，只保存查询定义                               |
+| 性能优化  | 显著提升查询效率，通过预存结果减少重复计算。其他 SQL可以利用该物化结果进行查询改写 | 虽然也可以提高查询效率，但是查询优化器不会进行查询改写 | 性能取决于底层数据表的查询效率,查询是计算逻辑每次重新计算                     |
+| 数据时效性 | 要求数据即时更新，以确保查询改写的准确性                        | 注重数据加工灵活性，可调整数据滞后性          | 数据新鲜度每次都是最新的                                      |
+| 更新机制  | 采用定时刷新机制，保持数据最新                             | 根据业务定义调整，不强制实时更新            | 不存储数据无需更新                                         |
+| 查询优化  | 优化器自动识别并使用预存结果                              | 不依赖于查询优化器的自动重写              |                                                   |
+| 使用场景  | 适合于预计算并复用查询结果的场景                            | 适合数据加工，可能数据不是最新的            | 适合于查询复杂度不高不涉及大量加工,如果涉及大数据量和很多复杂算子，查询很慢，因为每次都是重新计算 |
+| 运维    | 无复杂运维场景                                     | 动态表还支持了复杂的加列，版本回滚等功能        | 无复杂运维场景                                           |
+
+## 动态表刷新监控
+
+### **通过 SQL 命令查看刷新历史**
+
+您目前可以利用 SQL 命令来监控动态表的刷新历史。尽管该命令可能尚未全面上线，但您已经可以通过以下 SQL 语句来获取所有动态表的刷新情况概览：
+
+```SQL
+SHOW DYNAMIC TABLE REFRESH HISTORY [WHERE <condition>];
+```
+
+**过滤刷新历史**
+
+您可以使用 `WHERE` 子句来根据特定字段过滤信息，例如，要查看名为 `my_dy` 的动态表的刷新历史，可以使用以下命令：
+
+```SQL
+SHOW DYNAMIC TABLE REFRESH HISTORY WHERE name='my_dy';
+```
+
+| 字段名称             | 含义                                                                    |

+| virtual\_cluster | 使用的计算集群                                                               |
+| start\_time      | 刷新开始时间，                                                               |
+| end\_time        | 刷新结束时间                                                                |
+| duration         | 刷新耗时                                                                  |

+
+![](.topwrite/assets/image_1716280617859.png)
+
+* 您也可以通过job profile的输入记录来判断是否是增量读取数据
+
+## 动态表的成本
+
+#### **计算成本**
+
+动态表的刷新操作依赖于计算资源（Virtual Cluster）来执行，包括：
+
+* **定时刷新**：根据设定的时间间隔自动执行刷新。
+* **手动刷新**：用户根据需要手动触发刷新。
+
+这些刷新操作均会消耗计算资源。
+
+#### **存储成本**
+
+动态表同样需要存储空间来保存其具体化结果。与常规表一样，动态表支持：
+
+* **Time Travel**：允许用户访问过去7天内的任何时间点的数据。
+* **Time Travel 保留期限**：默认设置为7天，超过此期限后，数据将无法通过Time Travel访问，并且会被物理删除。
+
+**注意**：Time Travel 目前处于预览版，其默认保留周期为7天。在预览期间，用户可以免费查询7天内的数据版本，且不会对这段时间内的版本收费。预览期结束后，Lakehouse 将开始对使用 Time Travel 功能产生的存储费用进行单独计费。
+
+#### **刷新调度设置周期**
+
+**刷新速度影响因素**
+
+增量刷新的速度主要取决于两个因素：
+
+1. **源数据的变更量**：刷新操作需要处理的数据量越大，所需的时间就越长。
+2. **固定开销**：无论数据变更量大小，每次刷新都会产生的一些基本开销。
+
+**商业价值与刷新频率**
+
+* 如果数据新鲜度对您的业务价值不是至关重要，可以考虑降低刷新频率。这种策略可以减少因频繁刷新带来的计算开销。
+* 采用增量计算模式可以提高单次刷新的速度，因为它只处理自上次刷新以来发生变化的数据。
+
+**刷新成本与频率的平衡**
+
+* 刷新成本会随着刷新频率的增加而上升。因此，您需要在数据新鲜度所带来的商业价值和由此产生的计算成本之间做出权衡。
+* 高频率的刷新操作虽然可以保持数据的实时更新，但累积的计算成本也会随之增加。
+
+**建议**
+
+* 评估您的业务需求，确定数据新鲜度对您业务的具体价值。
+* 根据业务价值来设定合理的刷新频率，以优化成本效益。
+* 利用增量计算模式来提高刷新效率，减少不必要的计算开销。
+
+## 动态表限制
+
+* 增量刷新限制：不支持非确定性函数，比如random、current\_timestamp、current_date等
+* 不支持直接修改动态表数据，比如执行update、delete、truncate数据
+
+# 使用动态表加工案例
+
+## 使用动态表加工Lakehouse提供的样例数据
+
+Lakehouse 提供了一个名为 `ecommerce_events_multicategorystore_live` 的动态公共数据集，该数据集位于 `clickzetta_sample_data.clickzetta_sample_data.ecommerce_events_history` 路径下。这个数据集是实时更新的，并且可以被直接查询。
+
+实时数据集可用性：目前，`ecommerce_events_multicategorystore_live` 实时写入的公共数据集只在阿里云的上海区域提供。如果您的账户或服务不在该区域，您将无法查询此公共数据集。
+
+1. **编写SQL脚本使用DDL定义调度加工数据**
+
+```SQL
+CREATE  DYNAMIC TABLE event_type_count
+REFRESH interval 1 minute vcluster default
+as
+SELECT event_type, COUNT(*) AS events_count
+FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live
+GROUP BY event_type;
+--初始化DYNAMIC TABLE数据
+REFRESH DYNAMIC TABLE event_type_count;
+```
+
+2. 查看动态表刷新
+
+**使用命令查看动态表刷新**
+
+```SQL
+SHOW DYNAMIC TABLE REFRESH HISTORY WHERE name='event_type_count';
+```
+
+**在作业历史中查看dynamic table刷新历史**
+
+![](.topwrite/assets/image_1716280651911.png)
+
+点进详情中可以查看输入记录可以看到获取了增量多少条，诊断中可以查看增量执行SQL的计划
+
+![](.topwrite/assets/image_1716280668286.png)
+
+3. **在作业历史中看到增量刷新有数据后，可以查看数据变化**
+
+```SQL
+SELECT    *   FROM      event_type_count;
++-------------+--------------+
+| event_type  | events_count |
++-------------+--------------+
+| view        | 91634700     |
+| purchase    | 91630921     |
+| add_to_cart | 91622270     |
++-------------+--------------+
+--增量刷新完成后查看数据
+SELECT    *
+FROM      event_type_count;
++-------------+--------------+
+| event_type  | events_count |
++-------------+--------------+
+| purchase    | 91633135     |
+| add_to_cart | 91624515     |
+| view        | 91636913     |
++-------------+--------------+
+```
+
+## 使用STUDIO刷新调度动态表刷新任务
+
+在本次演示中，我们将通过以下步骤模拟增量数据的插入，并展示增量计算的效果：
+
+* **模拟增量数据插入**：使用 `INSERT INTO` 语句将模拟数据插入到指定表中，以此来模拟实际业务场景中的增量数据更新。
+* **利用 Studio 调度刷新**：随后，我们将利用 Lakehouse Studio 的调度功能来触发和执行增量数据的刷新任务。
+* **演示增量计算效果**：通过上述步骤，我们旨在展示增量计算如何高效地处理新插入的数据，并将更新反映在最终的查询结果中。
+
+1. 数据准备
+
+```SQL
+CREATE TABLE event_tb (
+    event STRING,
+    process DOUBLE,
+    event_time TIMESTAMP
+  );
+INSERT INTO event_tb VALUES
+  ('event-0', 20.0, TIMESTAMP '2023-09-20 14:43:13'),
+  ('event-0', 20.0, TIMESTAMP '2023-09-19 11:40:13'),
+  ('event-1', 21.0, TIMESTAMP '2023-09-19 14:30:14'),
+  ('event-1', 22.0, TIMESTAMP '2023-09-20 14:20:15');
+```
+
+2. 数据加工
+
+* 新建SQL脚本“1.时间处理dt”，将准备的数据使用SQL创建dy进行加工
+
+  ![](.topwrite/assets/image_1716280688236.png)
+
+```SQL
+CREATE dynamic TABLE IF NOT EXISTS event_gettime AS
+SELECT    event,
+          process,
+          YEAR(event_time) event_year,
+          MONTH(event_time) event_month,
+          DAY(event_time) event_day,
+          hour(event_time) event_hour,
+          minute(event_time) event_minute
+FROM      event_tb;
+
+REFRESH   dynamic TABLE event_gettime;
+```
+
+* 新建SQL脚本“2.聚合dy”，对上一步加工完的数据进行聚合操作
+
+  * ```SQL
+    CREATE dynamic TABLE IF NOT EXISTS event_group_minute AS
+    SELECT    event,
+              event_hour,
+              event_minute,
+              SUM(process) process_sum
+    FROM      event_gettime
+    GROUP BY  event,
+              event_hour,
+              event_minute;
+
+    refresh dynamic table event_group_minute;
+    ```
+
+3. 构建依赖和调度关系
+
+* 任务一“1.时间处理dt” 配置定时一分钟调度一次
+
+  * ![](.topwrite/assets/image_1716280711741.png)
+
+* 任务二“2.聚合dy” 按照任务一配置定时一分钟调度一次，并且在调度依赖中配置**依赖任务一“1.时间处理dt”**
+
+  * ![](.topwrite/assets/image_1716280739978.png)
+
+* 在数据开发界面每个任务点击提交任务
+
+  * ![](.topwrite/assets/image_1716280770050.png)
+
+4. 查看是否增量刷新
+
+```SQL
+--手动插入数据
+INSERT INTO event_tb VALUES
+  ('event-0', 20.0, TIMESTAMP '2024-01-20 14:43:13');
+ --查看event_gettime是否是增量刷新和增量刷新了多少条

+# Dynamic Table 支持参数化定义
+
+Dynamic Table 的参数化定义由两部分组成。
+
+* 创建分区动态表时，参数通过 SESSION_CONFIGS()['dt.args.xx'] 进行定义，用于写在 SQL 加工逻辑中，表示查询源表。SESSION_CONFIGS()是系统内置函数`'dt.args.xx'`：DT参数的名称，必须以`dt.arg.`开头，以避免与系统内部字段冲突。表达的含义和传统调度中select * from source_table where pt=${bizdate}，`SESSION_CONFIGS()['dt.args.pt']`等价于`pt=${bizdate}`。SESSION_CONFIGS()['dt.args.xx'] 返回值类型为 String。如果需要其它类型的参数，需要使用 CAST 函数进行转换，例如 `cast(SESSION_CONFIGS()['dt.args.xx'] as int)`。 如下案例：
+
+```sql
+--源表
+CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
+
+--定义动态表
+CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
+SELECT    col1,
+          nvl(col2, col1),
+          pt
+FROM      source_table
+WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
+```
+
+* 刷新时通过 `refresh dynamic table target_table partition(pt=${bizdate});` 指定分区值，其中 `pt=${bizdate}`。这对应于传统的 `insert overwrite target_table partition(pt=${bizdate})`。
+
+```sql
+--上面中定义的动态表分区字段是pt。因此刷新时传入pt=${bizdate}。这里假定bizdate是2024-11-13。刷新时应该使用如下语法
+--将2024-11-13传入到创建语句时的SESSION_CONFIGS()['dt.args.pt']中，替换为2024-11-13用于过滤source_table中的数据
+SET dt.args.pt = 2024-11-13;
+--刷新时指定pt=2024-11-13表示写入到动态表的2024-11-13分区中
+REFRESH   dynamic TABLE incremental_dt PARTITION (pt = '2024-11-13');
+```
+
+
+
+## 全量刷新与增量刷新
+
+### 全量刷新
+
+全量刷新发生在以下情况：
+
+1. **非分区表**：
+
+   - 如果在非分区表中使用了参数 `SESSION_CONFIGS()['dt.args.event_day']`，系统会根据参数值的变化决定刷新方式。
+   - 如果参数值保持不变，系统将执行**增量刷新**。
+   - 如果参数值发生变化，系统将执行**全量刷新**，因为参数值的变化等同于改变了表的定义。
+
+2. **分区表**：
+
+   * 如果分区已存在，但当前刷新的参数与上一次刷新的参数不相同，则进行一次全量刷新，因为参数值的变化会导致 SQL 加工逻辑发生变化。
+   * 如果分区不存在（即第一次刷新某个分区），则进行一次全量刷新。
+    
+
+```sql
+-- 创建源表
+CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
+
+-- 创建动态表
+CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
+SELECT    col1,
+          nvl(col2, col1),
+          pt
+FROM      source_table
+WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
+
+-- 示例 1：首次设置参数值为 2024-11-13
+SET dt.args.xxx = 1;
+SET dt.args.pt = 2024-11-13;
+--刷新为全量刷新
+REFRESH   dynamic TABLE incremental_dt PARTITION (pt = '2024-11-13');
+
+-- 示例 2：果第一次刷新某个分区，对应的参数是一个值，如果后面相同分区对应的参数发生了改变了，则相当于dt在这个分区的定义被修改了，所以会重新刷新，如下案例
+SET dt.args.xxx = 2;
+SET dt.args.pt = 2024-11-14;
+-- 刷新动态表，指定分区 pt=2024-11-14
+-- 系统会执行全量刷新，因为参数值发生了变化
+REFRESH   dynamic TABLE incremental_dt PARTITION (pt = '2024-11-14');
+
+```
+
+### 增量刷新
+
+增量刷新发生在以下情况：
+
+* 非分区表的参数值保持不变。
+* 分区表的参数值保持不变，且分区条件未改变。
+
+**示例代码**：
+
+```SQL
+
+-- 创建源表
+CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
+
+-- 定义动态表
+CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
+SELECT    col1,
+          nvl(col2, col1),
+          pt
+FROM      source_table
+WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
+
+-- 示例 1：首次设置参数值为 2024-11-13
+SET dt.args.pt = 2024-11-13;
+
+-- 刷新动态表，指定分区 pt=2024-11-13，全量刷新
+REFRESH   dynamic TABLE target_table PARTITION (pt = '2024-11-13');
+
+-- 示例 2：参数值和分区值未变化，再次刷新
+SET dt.args.pt = 2024-11-13;
+
+-- 刷新动态表，指定分区 pt=2024-11-13
+-- 系统会继续执行增量刷新
+REFRESH   dynamic TABLE target_table PARTITION (pt = '2024-11-13');
+```
+
+## 刷新语句
+
+参数化定义的Dynamic Table的刷新行为取决于表是否为分区表。
+
+### **非分区表刷新语法**：
+
+```SQL
+REFRESH DYNAMIC TABLE dt;。
+```
+
+* 非分区表的参数值保持不变，会进行增量刷新。非分区表的参数值发生变化，会进行全量刷新。
+
+### **分区表刷新语法**：
+
+```SQL
+REFRESH DYNAMIC TABLE dt PARTITION partition_spec;
+```
+
+语句刷新分区表时，必须按照表的分区层级顺序指定`partition_spec`。这意味着，如果表按照多个字段进行分区，这些字段需要按照从最高级别到最低级别的顺序被指定。
+* 多级分区，partition\_spec 需要根据分区的层级依次指定。例如，如果表有三级分区(day, hour, min)，必须从高到低依次指定，不能跳过某个分区。指定 day hour 是合法的，低级分区可以忽略，不用全声明。指定 day min 是不合法的，因为它跳过了 hour
+
+  * ```SQL
+    --不合法的
+    set dt.args.day = 1;
+    set dt.args.min = 1;
+    REFRESH   dynamic TABLE incremental_dt PARTITION (DAY = 1, MIN = 1);
+
+    --合法的
+    set dt.args.day = 1;
+     set dt.args.hour = 1;
+    REFRESH   dynamic TABLE incremental_dt PARTITION (DAY = 1, HOUR = 1);
+    ```
+**示例说明**：
+
+假设一个表按照`day`、`hour`和`min`三级进行分区，正确的`partition_spec`指定方式如下：
+
+* **合法指定**：可以指定高层级和部分低层级分区，但不可跳过任何中间层级分区。
+
+```SQL
+set dt.args.day=2024-11-13;
+set dt.args.hour=23;
+REFRESH DYNAMIC TABLE dt PARTITION (day='2024-11-13', hour=23); 
+```
+
+在这个例子中，`day`和`hour`被指定，而`min`分区可以被忽略。
+
+* **不合法指定**：跳过任何中间层级分区的指定是不被允许的。
+
+```SQL
+set dt.args.day=2024-11-13
+set dt.args.hour=30
+REFRESH DYNAMIC TABLE dt PARTITION (day='2024-11-13', min=30); 
+```
+
+## **注意事项**
+
+* **参数与分区一致性**：在执行 Dynamic Table 的刷新操作时，必须确保 SQL 计算逻辑中使用的分区参数值与 REFRESH 语句中指定的分区值保持一致。如果存在不一致，系统将在执行过程中报错。
+
+```SQL
+CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
+SELECT    col1,
+          nvl(col2, col1),
+          pt
+FROM      source_table
+WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
+
+--比如select col1, nvl(col2, col1), pt from source_table where pt = SESSION_CONFIGS()['dt.args.pt'];过滤出来对应的分区字段结果是9.系统将在执行过程中报错，
+set dt.args.event_day = 9;
+
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 19);
+
+```
+
+* **并发刷新任务**：在这些命令中，参数值与分区值匹配，因此可以并发执行而不会发生冲突。只要分区之间不存在冲突，系统允许同时执行多个分区的刷新任务。
+
+```SQL
+-- 为分区 event_day=19 设置参数并刷新
+set dt.args.event_day = 19;
+
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 19);
+
+-- 为分区 event_day=20 设置参数并刷新
+set dt.args.event_day = 20;
+
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 20);
+```
+
+## 使用案例
+
+* 动态表分区字段和源表中字段一致
+
+```sql
+CREATE TABLE event_tb_pt (
+    event STRING,
+    process DOUBLE,
+    event_time TIMESTAMP
+  );
+INSERT INTO event_tb_pt VALUES
+  ('event-0', 20.0, TIMESTAMP '2024-09-20 14:43:13'),
+  ('event-0', 20.0, TIMESTAMP '2024-09-19 11:40:13'),
+ ('event-1', 20.0, TIMESTAMP '2024-09-19 11:40:13');
+--创建动态表
+CREATE dynamic table  event_gettime_pt 
+partitioned by(event)
+AS SELECT
+  event,
+  process,
+  YEAR(event_time) event_year,
+  MONTH(event_time) event_month,
+  DAY(event_time) event_day
+FROM event_tb_pt
+where event=SESSION_CONFIGS()['dt.args.event'];
+--刷新动态表
+set dt.args.event = event-0;
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event = 'event-0');
+SELECT *FROM event_gettime_pt;
+```
+
+* 动态表分区字段和源表字段名不一致。过滤条件需要根据 `event` 字段过滤，而动态表的分区字段是 `event_year`。
+
+```sql
+DROP      TABLE IF EXISTS event_tb_pt;
+CREATE TABLE event_tb_pt (
+    event STRING,
+    process DOUBLE,
+    event_time TIMESTAMP
+  );

+ ('event-1', 20.0, TIMESTAMP '2024-09-19 11:40:13');
+--创建动态表

+--刷新动态表
+set dt.args.event = event-0;
+REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_year = 2024);
+SELECT * FROM  event_gettime_pt;
+```
+
+* 多级分区刷新
+
+```sql
+DROP      TABLE IF EXISTS event_tb_pt;
+CREATE TABLE event_tb_pt (
+    event STRING,
+    process DOUBLE,
+    event_time TIMESTAMP

+```
+
+## 场景案例
+
+**案例一：将离线任务转换为增量任务**
+
+本节将指导用户如何将原有的离线任务转换为增量任务，以实现更高效的数据处理。以下是一个基于“传统调度”的具体操作步骤，适用于业务逻辑按天对齐和按天调度刷新的场景。
+
+* 步骤 1：参数化原始 SQL。原始 SQL如下
+
+  ```sql
+  with tmp_channel as (
+    select
+      channel_code,
+      channel_name,
+      channel_type,
+      channel_uid
+    from dim.dim_shop_sales_channel_main
+    where pt = '${bizdate}'
+  ), tmp_bac_misc as (
+    select
+      mini_number,
+      bac_no
+    from dim.dim_customer_bac_misc_df
+    where pt = '${bizdate}'
+  ), tmp_fxiaoke as (
+    select
+      case
+        when record_type in ('dealer__c') then nvl(bac_no, account_no)
+        else account_no
+      end as channel_code,
+      id,
+      account_no
+    from ods.ods_account_obj as a
+    left join tmp_bac_misc on a.account_no = tmp_bac_misc.mini_number
+    where pt = '${bizdate}' and account_no is not null
+  --  and is_deleted = 0
+  --  and life_status not in ('invalid', 'ineffective')
+  )
+  insert overwrite table dim.dim_shop_sales_channel_misc partition(pt='${bizdate}')
+  select
+    tmp_channel.channel_code,
+    channel_name,
+    channel_type,
+    channel_uid,
+    id as fxiaoke_id,
+    account_no as fxiaoke_account_no
+  from tmp_channel
+  left join tmp_fxiaoke on tmp_channel.channel_code = tmp_fxiaoke.channel_code ;
+  ```
+
+  首先，需要将原始 SQL 中的所有由调度引擎传入的参数 `${bizdate}` 替换为 `SESSION_CONFIGS()['dt.args.bizdate']`。这一步骤将使得参数值可以通过配置动态传入，而不是硬编码在 SQL 中。
+
+  **原始 SQL 参数替换**:
+  将所有 `${bizdate}` 替换为 `SESSION_CONFIGS()['dt.args.bizdate']`：
+
+  ```sql
+  create dynamic table im.dim_shop_sales_channel_misc
+  partitioned by(pt)
+  with tmp_channel as (
+    select
+      channel_code,
+      channel_name,
+      channel_type,
+      channel_uidfrom dim.dim_shop_sales_channel_main
+      where pt = SESSION_CONFIGS()['dt.args.bizdate']
+  ), tmp_bac_misc as (
+    select
+      mini_number,
+      bac_nofrom dim.dim_customer_bac_misc_df
+      where pt = SESSION_CONFIGS()['dt.args.bizdate']
+  ), tmp_fxiaoke as (
+    select
+      case
+        when record_type in ('dealer__c') then nvl(bac_no, account_no)
+        else account_noend as channel_code,
+      id,
+      account_nofrom ods.ods_account_obj as aleft join tmp_bac_misc on a.account_no = tmp_bac_misc.mini_number
+      where pt = SESSION_CONFIGS()['dt.args.bizdate'] and account_no is not null
+  )
+  select
+    tmp_channel.channel_code,
+    channel_name,
+    channel_type,
+    channel_uid,
+    id as fxiaoke_id,
+    account_no as fxiaoke_account_no,
+    pt
+  from tmp_channel
+  left join tmp_fxiaoke on tmp_channel.channel_code = tmp_fxiaoke.channel_code
+  ;
+  ```
+
+* 步骤 2：调度刷新命令
+  在每次调度时，需要将参数 `dt.args.bizdate` 设置为具体的日期值，并执行刷新命令。
+
+  调度刷新命令示例
+
+  ```sql
+  SET dt.args.bizdate=20241130; -- ${bizdate}由Studio每次替换为具体的值
+  REFRESH DYNAMIC TABLE DT PARTITION (pt ='20241130');
+  ```
+
+**案例二：增量任务数据补数**
+
+在某些情况下，用户可能需要向已有的分区中补充数据。
+
+* 方法 1：向源表补充数据，用户可以直接向源表中补充数据。这些补充的数据将通过相应的 REFRESH 任务自动反映到 Dynamic Table（DT）中。
+
+  操作步骤
+
+  1. 直接向源表插入或更新数据。
+  2. 执行 REFRESH 任务，以将更改同步到 DT 中。
+* 方法 2：使用 DML 语句直接向 DT 补充数据，用户也可以使用 DML 语句直接向 DT 的特定分区中插入数据。
+  操作步骤
+  1. 使用 DML 语句向 DT 的特定分区插入数据。
+  2. 请注意，直接修改 DT 将导致下一次该分区的全量刷新。如果用户不希望出现全量刷新的结果，应避免调度该分区的 REFRESH 任务。
+     示例代码
+  ```sql
+  INSERT INTO DYNAMIC TABLE incremental_dt VALUES (...);
+  ```
+
+**注意事项**
+
+* 直接向 DT 插入的数据将参与 DT 的下游计算。如果下游的老分区不需要这些数据，请不要调度涉及这些数据的分区的 REFRESH 任务。
+* 其他未受影响的分区仍然可以进行增量刷新。
+
+**案例三：在不同 VC 中执行增量任务**
+
+对于参数化声明的分区化 DT，不同分区的刷新任务可以同时执行。用户可以根据需要将不同的 REFRESH 任务分配到不同的虚拟集群（VC）中执行。
+**操作步骤**：
+1. 根据时效性要求和资源需求，将不同的 REFRESH 任务分配到不同的 VC 中。
+2. 例如，对于时效性要求较高的新分区，可以将其 REFRESH 任务放在资源较多的大 VC 中执行。
+3. 对于其他老分区的补充任务，可以将其 REFRESH 任务放在资源较少的小 VC 中执行。

+# 动态表简介
+>【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请联系我们的技术支持同学协助处理。
+
+## 什么是动态表
+
+动态表（Dynamic Table）是云器Lakehouse的数据对象。创建时与表的区别是通过定义查询语句动态生成数据，刷新时自动获取的Base Table的增量数据，采用增量算法来进行计算，这样做的优势是大幅提升数据处理效率，尤其适用于处理大规模数据。
+## Dynamic Table捕获源表变化的时效性
+
+Dynamic Table根据源表对象的元数据修改提交时间来感知变化数据，源表发生变化并且完成元数据提交的变化可以被捕获，源表变化可能存在以下情况影响变化数据的时效性：
+
+* DML方式修改数据：源表发生DML操作，DML任务成功结束后，源表变化数据可被Dynamic Table访问；
+* 批量导入（Bulkload）：源表有批量任务导入，在批量导入任务成功结束后，源表的变化数据可被Dynamic Table访问；
+* 流式导入：源表通过Ingestion Service流式API写入数据，默认1Min提交变化，提交后源表的变化数据即可被Dynamic Table访问。注：对于流式写入的源表本身进行SQL查询时是实时可见，这里仅约束了基于该表的增量变化被Dynamic Table可见的时效。
+
+
+## 动态表应用场景
+
+### 不适用于增量场景
+1. 查询操作里存在大量数据排序需求，例如使用了 Orderby 子句。
+2. Window 函数需要对数据进行排序（RowNumber=1 的情况除外），并且增量数据中包含多个数据量特别大的 Partition。
+3. 数据缺乏良好的聚集性，无法通过 Joinkey、Aggregat key、Window partition key 等清晰地将冷数据和热数据区分开来。
+4. Aggregat key中目前支持的类型有CHAR、VARCHAR、STRING、TINYINT、SMALLINT、INT、BIGINT、DECIMAL、BOOLEAN、DATE如果有其他类型则不支持
+
+### 面向实时加工场景
+
+在实时数据加工场景中，数据以持续且快速的方式流入系统。传统的数据处理方法，如完全重载（Full Reload）或全量刷新（Full Refresh），在性能和资源消耗方面可能不够高效，特别是在处理大规模数据流时。动态表采用增量计算方法，仅处理自上次更新以来变化的数据，从而显著减少了计算资源的消耗。
+
+**动态表的优势**：
+
+* **实时性**：能够迅速将新数据变更反映到数据仓库中，保持数据的高新鲜度。
+* **成本效益**：通过设置合理的刷新间隔，可以平衡性能与成本，实现资源的最优利用。
+* **资源弹性**：Lakehouse的资源可以轻松实现弹性扩展，尤其在处理峰值数据流入时更具优势。
+* **按需计算**：未来Lakehouse将实现按需启动计算资源，即仅在有数据需要计算时才会启动相应资源，进一步提高效率和降低成本。
+
+**应用实例**：
+
+**背景**： 一家电子商务公司希望实时分析其销售数据，以便快速做出库存和定价决策。数据以高速率持续流入系统，需要一种高效的数据处理方法。
+
+**挑战**：
+
+* 传统的全量数据处理方法在性能和资源消耗方面效率低下，尤其是在高峰时段。
+* 需要一种能够快速响应数据变更并保持数据新鲜的处理机制。
+
+**解决方案**：
+
+* 引入动态表，采用增量计算方法，仅处理自上次更新以来变化的数据。
+
+**动态表的优势**：
+
+1. **实时性**： 动态表能够迅速捕捉并反映数据变更，确保决策基于最新的销售数据。
+
+2. **成本效益**：通过动态表，公司可以根据实际需求设置合理的数据刷新间隔，避免了不必要的计算资源浪费。
+
+3. **资源弹性**：在促销活动或节假日等流量高峰时段，Lakehouse的资源可以按需扩展，以应对数据流入的峰值，而不必长期维持高额的资源配置。
+
+4. **按需计算**：未来，Lakehouse的按需计算功能将进一步提高效率，仅在有数据需要计算时才启动资源，从而降低成本。
+
+### 数据新鲜度要求较高的固定维度分析查询场景
+
+在固定维度分析查询场景中，我们追求的是能够提供近乎实时的分析结果。传统的视图查询可以实现这一点，但如果涉及大量数据转换，则可能会导致查询速度变慢。为了解决这个问题，我们可以将转换后的结果进行物化，这样在查询时就可以直接返回这些结果，从而提高查询速度。物化结果可以采用传统的表格或者dynamic table。
+
+使用传统的表可以提供最高的性能，因为它们在查询时只返回预先转换好的数据。但这种方法的缺点是，需要定期评估数据转换的时间，并通过调度进行全量计算，这通常会占用较长的时间。
+
+dynamic table结合了增量计算的优势。通过仅更新自上次加载以来发生变化的记录，dynamic table不仅减少了每次构建的时间，通过缩短时间间隔还保持了数据的最新性。
+
+### 注意事项
+
+* 在处理源端大量变化数据时，计算任务可能接近全量计算的负载。尽管增量计算在效率上具有明显优势，但如果您设置的刷新间隔过短，可能会导致任务积压。这是因为每次刷新操作本身需要一定的时间来完成，如果这个时间超过了您设置的刷新间隔，将会导致后续刷新任务的排队等待。
+  * **建议**：
+    * **合理设置刷新间隔**：根据数据变更的频率和任务的刷新耗时，合理设置刷新间隔，以避免刷新操作的积压。
+    * **监控和调整**：持续监控数据变更模式和系统性能，根据实际情况调整刷新间隔，以实现效率和资源的最优化利用。
+* 在编写算子时参考算子是如何增量刷新中的注意事项来优化增量刷新任务
+### 不适合场景
+1. 涉及大量 Outer Join 操作，且 Outer Join 右表数据频繁变动。
+2. 是否存在大量数据排序操作（如使用 Order by）。
+3. Window 操作需对数据排序（RowNumber=1 情况除外），同时增量数据包含多个数据量极为庞大的 Partition。
+4. 数据是否具有良好的聚集特性，例如能否通过 Join key、Aggregate key 或 Window partition key 明确区分冷数据与热数据。
+
+## 动态表工作原理概述
+
+### 如何获取变化的数据
+
+* MetaService（元数据服务，Lakehouse 的一个组件服务）记录了 Lakehouse 里每张表的每一个历史数据版本

+  * 基本概念: 一张表的 **Snapshot（全量**） VS **Delta（变化**）
+
+
+## Lakehouse Dynamic Table 刷新机制
+
+Lakehouse 目前使用调度机制来更新 Dynamic Table。支持以下几种调度模式：
+
+1. **在** **DDL** **语句中定义调度属性**
+2. **在 Lakehouse Studio 中定义调度**
+3. **使用第三方调度引擎提交 Refresh 作业**
+
+|                          | 使用方式                                                                                                    | 优点                                                        | 缺点                                                                                    |
+| ------------------------ | ------------------------------------------------------------------------------------------------------- | --------------------------------------------------------- | ------------------------------------------------------------------------------------- |
+| DDL语句中定义调度属性             | 在refreshOption中定义刷新间隔，具体使用方式[参考动态表创建文档](<create-dynamic-table.md>)。目前限制刷新间隔一分钟。 | 简单易用，可以快速设置刷新选项。不依赖任何第三方工具。                               | 当前Lakehouse不支持在 Dynamic Table 上定义严格的上下游依赖关系。在 DDL 定义中依赖时间调度。可以通过时间间隔的方式先保证上游刷新完成再调度下游 |
+| 在 Lakehouse Studio 中定义调度 | 可以在 Lakehouse Studio 中通过可视化界面配置调度，具体配置方式可以参考[任务开发调度文档](taskdevelop.md)。目前限制刷新间隔一分钟。                     | 可视化配置，用户友好。支持调度依赖配置，确保上游刷新完成后再刷新下游。支持单节点运行监控，如失败告警、超时告警等。 |                                                                                       |
+| 使用第三方调度引擎提交 Refresh 作业   | 通过下载 Lakehouse 客户端命令，使用 cron 表达式定时提交 Refresh 任务。或者通过 Java Jdbc 接口自定义提交 Refresh 命令。                      | 您可以更灵活地控制作业的提交和配置调度信息，时间间隔没有限制                            | 需要依赖第三方调度。引入第三方调度系统                                                                   |
+
+## 动态表和物化视图、普通视图的比较
+
+从Lakehouse的实现机制上来看，动态表是基于传统的物化视图来演进的，虽然两者有一些共性，但是定位上存在很大区别
+
+|       | 物化视图                                        | 动态表                         | 普通视图                                              |
+| ----- | ------------------------------------------- | --------------------------- | ------------------------------------------------- |
+| 定义    | 一种预计算并存储查询结果的特殊视图                           | 专注于数据加工的高效工具                | 一种虚拟表，不存储数据，只保存查询定义                               |
+| 性能优化  | 显著提升查询效率，通过预存结果减少重复计算。其他 SQL可以利用该物化结果进行查询改写 | 虽然也可以提高查询效率，但是查询优化器不会进行查询改写 | 性能取决于底层数据表的查询效率,查询是计算逻辑每次重新计算                     |
+| 数据时效性 | 要求数据即时更新，以确保查询改写的准确性                        | 注重数据加工灵活性，可调整数据滞后性          | 数据新鲜度每次都是最新的                                      |
+| 更新机制  | 采用定时刷新机制，保持数据最新                             | 根据业务定义调整，不强制实时更新            | 不存储数据无需更新                                         |
+| 查询优化  | 优化器自动识别并使用预存结果                              | 不依赖于查询优化器的自动重写              |                                                   |
+| 使用场景  | 适合于预计算并复用查询结果的场景                            | 适合数据加工，可能数据不是最新的            | 适合于查询复杂度不高不涉及大量加工,如果涉及大数据量和很多复杂算子，查询很慢，因为每次都是重新计算 |
+| 运维    | 无复杂运维场景                                     | 动态表还支持了复杂的加列，版本回滚等功能        | 无复杂运维场景                                           |
+
+## 动态表刷新监控
+
+### 通过 SQL 命令查看刷新历史
+
+您目前可以利用 SQL 命令来监控动态表的刷新历史。尽管该命令可能尚未全面上线，但您已经可以通过以下 SQL 语句来获取所有动态表的刷新情况概览：
+
+```SQL
+SHOW DYNAMIC TABLE REFRESH HISTORY [WHERE <condition>];
+```
+
+**过滤刷新历史**
+
+您可以使用 `WHERE` 子句来根据特定字段过滤信息，例如，要查看名为 `my_dy` 的动态表的刷新历史，可以使用以下命令：
+
+```SQL
+SHOW DYNAMIC TABLE REFRESH HISTORY WHERE name='my_dy';
+```
+
+| 字段名称             | 含义                                                                    |

+
+![](.topwrite/assets/image_1716280617859.png)
+
+* 您也可以通过job profile的输入记录来判断是否是增量读取数据
+
+## 动态表的成本
+
+#### 计算成本
+
+动态表的刷新操作依赖于计算资源（Virtual Cluster）来执行，包括：
+
+* **定时刷新**：根据设定的时间间隔自动执行刷新。
+* **手动刷新**：用户根据需要手动触发刷新。
+
+这些刷新操作均会消耗计算资源。
+
+#### 存储成本
+
+动态表同样需要存储空间来保存其具体化结果。与常规表一样，动态表支持：
+
+* **Time Travel**：允许用户访问过去7天内的任何时间点的数据。
+* **Time Travel 保留期限**：默认设置为7天，超过此期限后，数据将无法通过Time Travel访问，并且会被物理删除。
+
+
+#### 刷新调度设置周期
+
+**刷新速度影响因素**
+
+增量刷新的速度主要取决于两个因素：
+
+1. **源数据的变更量**：刷新操作需要处理的数据量越大，所需的时间就越长。
+2. **固定开销**：无论数据变更量大小，每次刷新都会产生的一些基本开销。
+
+**商业价值与刷新频率**
+
+* 如果数据新鲜度对您的业务价值不是至关重要，可以考虑降低刷新频率。这种策略可以减少因频繁刷新带来的计算开销。
+* 采用增量计算模式可以提高单次刷新的速度，因为它只处理自上次刷新以来发生变化的数据。
+
+**刷新成本与频率的平衡**
+
+* 刷新成本会随着刷新频率的增加而上升。因此，您需要在数据新鲜度所带来的商业价值和由此产生的计算成本之间做出权衡。
+* 高频率的刷新操作虽然可以保持数据的实时更新，但累积的计算成本也会随之增加。
+
+**建议**
+
+* 评估您的业务需求，确定数据新鲜度对您业务的具体价值。
+* 根据业务价值来设定合理的刷新频率，以优化成本效益。
+* 利用增量计算模式来提高刷新效率，减少不必要的计算开销。
+
+## 动态表限制
+
+* 增量刷新限制：不支持非确定性函数，比如random、current\_timestmap、current_date等
+* 不支持直接修改动态表数据，比如执行update、delete、truncate数据
+
+# 使用动态表加工案例
+
+## 使用动态表加工Lakehouse提供的样例数据
+
+Lakehouse 提供了一个名为 `ecommerce_events_multicategorystore_live` 的动态公共数据集，该数据集位于 `clickzetta_sample_data.clickzetta_sample_data.ecommerce_events_history` 路径下。这个数据集是实时更新的，并且可以被直接查询。
+
+实时数据集可用性：目前，`ecommerce_events_multicategorystore_live` 实时写入的公共数据集只在阿里云的上海区域提供。如果您的账户或服务不在该区域，您将无法查询此公共数据集。
+
+1. **编写SQL脚本使用DDL定义调度加工数据**
+
+```SQL
+CREATE  DYNAMIC TABLE event_type_count
+REFRESH interval 1 minute vcluster default
+as
+SELECT event_type, COUNT(*) AS events_count
+FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live
+GROUP BY event_type;
+--初始化DYNAMIC TABLE数据
+REFRESH DYNAMIC TABLE event_type_count;
+```
+
+2. 查看动态表刷新
+
+**使用命令查看动态表刷新**
+
+```SQL
+SHOW DYNAMIC TABLE REFRESH HISTORY WHERE name='event_type_count';
+```
+
+**在作业历史中查看dynamic table刷新历史**
+
+![](.topwrite/assets/image_1716280651911.png)
+
+点进详情中可以查看输入记录可以看到获取了增量多少条，诊断中可以查看增量执行SQL的计划
+
+![](.topwrite/assets/image_1716280668286.png)
+
+3. **在作业历史中看到增量刷新有数据后，可以查看数据变化**
+
+```SQL
+SELECT    *   FROM      event_type_count;
++-------------+--------------+
+| event_type  | events_count |
++-------------+--------------+
+| view        | 91634700     |
+| purchase    | 91630921     |
+| add_to_cart | 91622270     |
++-------------+--------------+
+--增量刷新完成后查看数据
+SELECT    *
+FROM      event_type_count;
++-------------+--------------+
+| event_type  | events_count |
++-------------+--------------+
+| purchase    | 91633135     |
+| add_to_cart | 91624515     |
+| view        | 91636913     |
++-------------+--------------+
+```
+
+## 使用STUDIO刷新调度动态表刷新任务
+
+在本次演示中，我们将通过以下步骤模拟增量数据的插入，并展示增量计算的效果：
+
+* **模拟增量数据插入**：使用 `INSERT INTO` 语句将模拟数据插入到指定表中，以此来模拟实际业务场景中的增量数据更新。
+* **利用 Studio 调度刷新**：随后，我们将利用 Lakehouse Studio 的调度功能来触发和执行增量数据的刷新任务。
+* **演示增量计算效果**：通过上述步骤，我们旨在展示增量计算如何高效地处理新插入的数据，并将更新反映在最终的查询结果中。
+
+1. 数据准备
+
+```SQL
+CREATE TABLE event_tb (
+    event STRING,
+    process DOUBLE,
+    event_time TIMESTAMP
+  );
+INSERT INTO event_tb VALUES
+  ('event-0', 20.0, TIMESTAMP '2023-09-20 14:43:13'),
+  ('event-0', 20.0, TIMESTAMP '2023-09-19 11:40:13'),
+  ('event-1', 21.0, TIMESTAMP '2023-09-19 14:30:14'),
+  ('event-1', 22.0, TIMESTAMP '2023-09-20 14:20:15');
+```
+
+2. 数据加工
+
+* 新建SQL脚本“1.时间处理dt”，将准备的数据使用SQL创建dy进行加工
+
+  ![](.topwrite/assets/image_1716280688236.png)
+
+```SQL
+CREATE dynamic TABLE IF NOT EXISTS event_gettime AS
+SELECT    event,
+          process,
+          YEAR(event_time) event_year,
+          MONTH(event_time) event_month,
+          DAY(event_time) event_day,
+          hour(event_time) event_hour,
+          minute(event_time) event_minute
+FROM      event_tb;
+
+REFRESH   dynamic TABLE event_gettime;
+```
+
+* 新建SQL脚本“2.聚合dy”，对上一步加工完的数据进行聚合操作
+
+  * ```SQL
+    CREATE dynamic TABLE IF NOT EXISTS event_group_minute AS
+    SELECT    event,
+              event_hour,
+              event_minute,
+              SUM(process) process_sum
+    FROM      event_gettime
+    GROUP BY  event,
+              event_hour,
+              event_minute;
+
+    refresh dynamic table event_group_minute;
+    ```
+
+3. 构建依赖和调度关系
+
+* 任务一“1.时间处理dy” 配置定时一分钟调度一次
+
+  * ![](.topwrite/assets/image_1716280711741.png)
+
+* 任务二“2.聚合dy” 按照任务一配置定时一分钟调度一次并且在调度依赖中配置**依赖任务一“1.时间处理dy**”
+
+  * ![](.topwrite/assets/image_1716280739978.png)
+
+* 在数据开发界面每个任务点击提交任务
+
+  * ![](.topwrite/assets/image_1716280770050.png)
+
+4. 查看是否增量刷新
+
+```SQL
+--手动插入数据
+INSERT INTO event_tb VALUES
+  ('event-0', 20.0, TIMESTAMP '2024-01-20 14:43:13');
+ --查看event_gettime是否是增量刷新和增量刷新了多少条
+SHOW DYNAMIC TABLE REFRESH HISTORY WHERE name='event_gettime';

+## **约束限制**
+* 除了列出的 current_date非确定性函数，其他非确定性函数不支持。如果使用非确定性函数创建则报错
+* 建议使用GP型集群来刷新动态表。原因：动态表刷新过程中会根据内置策略自动执行小文件合并操作，而AP型集群不支持此功能。

+# 动态表任务
+
+>【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请在页面申请或者联系我们的技术支持同学协助处理。
+
+
+Web-IDE 提供了支持协作开发的向导式动态表任务模板，提高动态表任务的开发效率，同时支持与任务运维、监控告警功能打通，增强面向生产的运维监控能力。
+
+Web-IDE 中动态表的开发过程，是通过可视化的向导方式辅助用户编写创建动态表所需的必要内容。例如：动态表所在的schema、动态表名称、刷新周期、动态表查询逻辑等。开发动态表脚本完成后，执行任务"提交"时系统会根据脚本内容在目标位置创建动态表、动态表的刷新策略配置进行自动化调度，从而实现动态表任务的部署上线。
+
+* 第一步：新建动态表任务
+
+您可以在Studio的IDE开发环境中，通过新建任务的方式添加"动态表"类型的任务。
+
+![](.topwrite/assets/image_1722413586664.png)
+
+新建时，为任务指定名称并选择保存位置。
+
+![](.topwrite/assets/image_1722413608121.png =347)
+
+* 第二步：为动态表命名并编写动态表的SELECT查询语句
+
+首先，填写动态表在提交后将要保存的schema位置以及动态表名称
+
+![](.topwrite/assets/image_1722413623690.png)
+
+其次，在SQL代码区域编写和测试动态表的查询语句。
+
+在 SQL 代码区编写处理转换的 SELECT 语句，设置运行 SQL 的集群名称（当动态表部署运行时，将默认使用该集群运行刷新任务），同时可以通过运行按钮测试运行 SELECT 语句以确保处理逻辑的正确性。
+
+![](.topwrite/assets/image_1722413647339.png)
+
+最后，通过Explain按钮校验查询语句的语法正确性并保存动态表的模型定义
+
+点击按钮检查 SELECT 查询语法的正确性，检查字段名称及数据类型是否符合预期。确认正确后点击弹出窗口的"确定并继续"按钮，系统将保存动态表的定义并退出SQL代码编辑状态。
+
+![](.topwrite/assets/image_1722413661168.png)
+
+* 第三步：修改和调整动态表配置并提交部署
+
+在完成动态表SQL代码开发并退出SQL编辑模式后，您将看到包括动态表基本信息、运行参数、SQL代码、动态表字段、动态表分区及分桶相关的默认配置。
+
+![](.topwrite/assets/image_1722413674413.png)
+
+在动态表模型定义提交部署至 Lakehouse 数据环境前，您还需要根据业务需要检查并修改以下配置信息，以满足生产运行需求。以下是动态表支持调整和修改的配置项目，请根据需要进行配置。
+
+| 配置项     | 默认值           | 配置说明                                                                 | 示例                                            |

+| SQL代码   | 上次保存的代码内容     | 可选项。当您在保存后，希望对 SQL 代码进行调整时，可通过编辑方式修改并保存。                                | ![](.topwrite/assets/image_1722413830727.png) |
+| 编辑字段    | 无             | 在编辑字段时，您可以设置：\* 字段注释。为字段添加注释信息                                       |                                               |
+
+* 设置分区字段。添加特定字段为分区字段，支持普通分区字段、Transform分区
+
+* 设置动态表分桶字段和数量：添加特定字段为分桶字段，并设置分桶数量。开启分桶设置后，分桶数默认值为 256 个。
+
+* 设置排序字段。可指定1个或多个字段为排序字段，指定排序方法。 | ![](.topwrite/assets/image_1722413842446.png) |
+
+* 第四步：提交部署动态表模型到目标环境
+
+完成SQL开发和动态表配置后，您可以通过"DDL预览"查看动态表模型完整的DDL定义。
+
+![](.topwrite/assets/image_1722413857683.png)
+
+确认符合预期后，您可以点击动态表任务右侧的"提交"按钮，系统弹出与上次保存代码版本的对比：
+
+![](.topwrite/assets/image_1722413868003.png)
+
+确定提交后，您的模型开发内容最终将通过 DDL 命令在 Lakehouse 目标数据环境中执行，创建动态表数据对象。Lakehouse系统将自动根据动态表的刷新策略进行调度执行。

+# Studio动态表任务与动态表对象的关系
+Studio在开发模块提供了名为"动态表"的任务类型，借助该任务类型提供对动态表任务的开发、运维及监控告警功能支持。在"开发"模块提交动态表任务时，系统将根据代码定义同步创建Lakehouse动态表对象，在"运维"模块下线动态表任务时，系统将自动删除Lakehouse动态表对象。
+注意：在 Studio 开发模块使用动态表任务创建动态表时，系统会检查目标位置是否已经存在 Lakehouse 动态表对象，并提示同名对象存在导致无法创建。此时可修改新建动态表任务名称或在手工删除先前存在的Lakehouse动态表对象后再创建Studio动态表任务。
+
+# 约束与限制
+Studio监控告警模块不支持对直接使用CREATE DYNAMIC TABLE语句创建的动态表进行告警配置。如需使用Studio监控告警对动态表创建告警规则，请通过Web IDE开发模块使用"动态表"任务创建并提交。

+# 动态表（Dynamic Table）
+
+>**【预览发布】本功能当前处于受邀预览阶段。如需试用，请通过官网联系方式联系云器科技。**
+
+动态表（Dynamic Table）是云器 Lakehouse 解决方案中的一项创新特性，为用户提供了一种灵活且高效的数据处理与存储方法。与传统静态表相比，动态表不直接存储数据，而是通过定义的查询语句动态生成数据。这种方式在处理大规模数据集和实现数据实时更新方面展现出显著的优势。
+
+## 动态表的核心特性
+
+1.  **查询结果即表**：动态表基于定义的查询语句动态生成数据集，每次查询都可能产生一个全新的数据集，即动态表的内容。
+2. **增量刷新机制**：动态表支持增量刷新，仅在底层数据源发生变化时触发查询语句的执行和内容的更新，大幅提升数据处理效率，尤其适用于处理大规模数据。
+3. **操作限制**：由于数据由查询生成，动态表不支持传统的`UPDATE`、`DELETE`、`INSERT`等直接数据操作，以确保数据的一致性和准确性。
+
+## 动态表的应用场景
+
+*   **数据仓库**：动态表可用于存储经过处理和转换的数据，便于后续的数据分析和报告生成。
+*   **实时数据应用**：对于需要实时数据更新的应用场景，动态表能够提供快速的数据刷新能力，保持数据的时效性。
+*   **数据ETL过程**：在数据提取、转换和加载（ETL）过程中，动态表可作为中间存储，保存转换后的数据集。
+
+## Materialized View和Dynamic Table区别
+
+从 Lakehouse 的实现机制上来看，动态表是基于传统的物化视图演进而来。虽然两者有一些共性，但在定位上存在很大区别。
+
+**物化视图：性能优化利器**
+物化视图是一种预计算并存储查询结果的特殊视图，能够显著提升查询效率。与传统视图不同，物化视图将计算结果保存在类似表的结构中，使得后续相似查询能够被优化器自动识别并直接使用预存结果，从而减少重复计算，加快查询速度。
+
+**动态表：数据加工的高效工具**
+动态表专注于数据加工，虽然也能提升查询性能，但并不依赖于查询优化器的自动重写。物化视图只有保持数据是最新的才能进行查询改写，而动态表面向加工场景，其数据可能并不是最新的。
+
+**传统物化视图在某些产品中具有以下限制，目前 Lakehouse 没有这些限制**：
+
+1.  只能基于单个基表。物化视图不能基于复杂查询（即具有联接或嵌套视图的查询）。
+
+2.  物化视图不一定是增量刷新，不同系统的实现方式各异。少量系统为了节省计算资源、加快加工速度，在部分算子中实现了增量计算。
+
+**动态表的先进特性**：
+
+1.  **增量识别与优化**：支持大数据环境下的文件粒度增量识别，实现实时增量读取和计算优化，以及写入优化。
+2.  **智能决策**：通过基于成本的优化器（Cost-Based Optimizer）智能选择全量、增量或部分增量计算，以适应不同查询需求。
+3.  **实时任务运维**：提供数据版本管理、回退和重跑等机制，为实时任务的运维提供全面支持。
+
+**数据时效性考量**：
+
+* 物化视图要求数据的即时更新，以确保查询改写的准确性。在基表数据变更时，Lakehouse 采用定时刷新机制，确保物化视图的数据始终保持最新。
+* 动态表则更注重数据加工的灵活性，根据业务定义来调整数据的滞后性，而不强制要求数据必须实时更新。
+
+## 动态表管理操作指南
+
+*   **创建动态表**：用户可以通过特定的语法定义新的动态表，并指定用于数据转换的 SQL 查询语句。具体语法和操作步骤详见 [创建动态表](create-dynamic-table.md) 文档。
+*   **删除动态表**：若动态表不再需要，可使用 `DROP TABLE` 命令将其删除。执行删除操作前，请确保数据已备份或确认不再需要，因为该操作会移除动态表的定义及其数据。具体语法和操作步骤详见 [删除Dynamic Table](drop-dynamic-table.md) 文档。
+*   **查看动态表刷新历史**：通过 `SHOW DYNAMIC TABLE REFRESH HISTORY` 命令查看指定动态表的刷新历史，可监控刷新作业的执行状态（成功与否）、运行时长、增量/全量刷新模式、处理的记录数量等信息。
+
+## 数据加工与增量计算
+
+动态表在数据加工中发挥着重要作用。通过定义查询语句，用户能够实现数据的提取、转换和加载（ETL）。同时，动态表支持增量计算，仅在数据源发生变化时触发数据更新，有效减少数据处理的时间和资源消耗。有关动态表的增量计算和数据加工的详细信息，请参阅 [数据加工与增量计算](dynamic_table_summary.md) 文档。

+# dbt ClickZetta adapter 使用指南
+
+## dbt 简介
+
+dbt（Data Build Tool）是一款开源的数据建模工具，旨在将软件工程的方法引入数据建模开发过程。dbt 支持多种数据源，使得数据开发人员能够实现跨平台、质量可控的数据开发。dbt 拥有活跃的社区，提供了丰富的扩展组件，如数据质量、与其他系统集成等，让数据开发变得更加简便。
+
+云器推出了 `dbt-clickzetta` 适配器，以支持 dbt 版本 1.5+。本文将结合 dbt 标准示例 [Jaffle Shop](https://github.com/dbt-labs/jaffle-shop-classic)，详细介绍适配器的安装和使用方法。
+
+## 准备环境
+
+1. 安装 dbt-clickzetta 适配器（已集成 dbt-core 和 dbt-extractor）：
+   ```shell
+   pip install dbt-clickzetta
+   ```
+2. 准备 dbt 项目：
+   ```shell
+   git clone https://github.com/dbt-labs/jaffle-shop-classic.git
+   ```
+3. 在版本控制系统中，管理和编辑项目。
+
+## 配置
+
+在 dbt 项目根目录（即 `jaffle_shop` 目录）编辑 `profiles.yml` 文件，如下所示：
+
+```yaml
+jaffle_shop:
+  target: prod
+  outputs:
+    prod:
+      type: clickzetta
+      service: region_id.api.clickzetta.com
+      instance: instance_name
+      username: user_name
+      password: password
+      workspace: workspace_name
+      schema: jaffle_shop
+      vcluster: default
+```
+
+参数说明：
+
+* 官方指定的 dbt profile 参数（如上述示例中的 jaffle\_shop、target 等），请参考 [dbt 官方文档](https://docs.getdbt.com/docs/core/connect-data-platform/connection-profiles)。
+* dbt-clickzetta 插件识别的参数包括：
+  * type: 固定为 clickzetta
+  * service: ClickZetta Lakehouse 服务地址
+  * instance: 实例名称
+  * username: 用户名
+  * password: 密码
+  * workspace: 工作空间名称
+  * schema: Schema 名称
+  * vcluster: 计算集群名称
+
+为方便使用 `dbt` 命令，可将 `profiles.yml` 文件拷贝到用户目录下：
+
+```shell
+mkdir ~/.dbt/ && cp profiles.yml ~/.dbt/
+```
+
+运行 `dbt debug` 以验证配置是否正确。
+
+## 运行 dbt 项目
+
+### 1. 上传数据
+
+运行 `dbt seed`，将项目中的 CSV 数据上传到 ClickZetta Lakehouse。
+
+### 2. 运行模型
+
+使用 `dbt run`，dbt 将根据 models 目录中的文件描述自动生成 SQL 并执行。
+
+### 3. 验证产出
+
+运行 `dbt test`，对产出表进行验证。测试是您对 dbt 项目中的模型和其他资源（例如源、种子和快照）所做的断言。当您运行 `dbt test` 时，dbt 会告诉您项目中的每个测试是否通过或失败。
+
+### 4. 生成并查看报告
+

+    columns:
+      - name: customer_id
+        tests:
+          - unique
+          - not_null
+```
+
+运行 `dbt test` 来执行测试。
+
+### 示例 4：使用钩子（Hook）
+

+
+```toml
+# .streamlit/secrets.toml
+
+[connections.connection_name]
+url = "clickzetta://username:password@instance.api.clickzetta.com/quickstart_ws?schema=public&virtualcluster=default"
+```
+
+### 编写应用代码
+
+创建一个名为 `demo.py` 的文件，并编写以下代码：
+
+```python
+# demo.py
+import streamlit as st
+
+# 根据 secrets.toml 中的配置创建 SQL 连接。
+conn = st.experimental_connection('connection_name', type='sql')
+
+# 输入 SQL 查询语句。
+sql = st.text_area('在这里输入您的 SQL 查询语句')
+
+# 执行查询并展示结果。
+if st.button('运行查询') and sql:
+    result = conn.query(sql)
+    st.dataframe(result)
+```
+
+### 运行应用
+
+使用以下命令运行应用：
+
+```bash
+streamlit run demo.py
+```
+

+
+### 示例 SQL 查询
+
+以下是一个示例 SQL 查询，用于从 ClickZetta Lakehouse 中获取最近 24 小时内的购买事件数据：
+
+```sql
+SELECT
+  brand,
+  COUNT(DISTINCT user_id) AS unique_user_count,
+  SUM(price) AS sum_price
+FROM
+  clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live
+WHERE
+  event_time >= (NOW() - INTERVAL '24' HOUR)
+  AND event_type = 'purchase'
+GROUP BY
+  brand
+ORDER BY
+  sum_price DESC
+LIMIT 10;
+```
+
+![Streamlit 应用运行效果截图](streamlit-demo.png)
+
+## 进阶示例
+
+### 添加图表展示
+
+为了更好地展示数据，您可以使用 Streamlit 的 `st.plotly_chart` 函数，将查询结果以图表形式展示。首先，安装 `pandas` 和 `plotly` 库：
+
+```bash
+pip install pandas plotly
+```
+
+然后，在 `demo.py` 中添加以下代码：
+
+```python
+import pandas as pd
+import plotly.express as px
+
+# ...
+
+if st.button('生成图表') and sql:
+    result = conn.query(sql)
+    df = pd.DataFrame(result)
+
+    fig = px.bar(df, x='brand', y='sum_price', title='各品牌销售额')
+    st.plotly_chart(fig)
+```

+# Trino Clickzetta Connector 使用指南
+
+## Trino 简介
+
+Trino 是一个高性能的开源分布式 SQL 查询引擎，它支持在多种数据源上执行查询，包括但不限于 Hive、MySQL、PostgreSQL、MongoDB、Redis、Cassandra、Kafka 等。Trino 常用于离线查询加速和多数据源联邦查询，为用户提供便捷的数据处理和分析体验。
+
+本文档将介绍如何使用 Trino-Clickzetta 插件，通过 Trino 直接访问和分析 Clickzetta Lakehouse 中的数据。
+
+## 准备工作
+
+1.  请确保已安装 Trino。您可以选择下载 [Trino 402 版本服务器](https://repo1.maven.org/maven2/io/trino/trino-server/402/trino-server-402.tar.gz)。
+2.  下载 Trino-Clickzetta 插件。访问 [插件下载页面](https://autolake-dev-beijing.oss-cn-beijing.aliyuncs.com/clickzetta-tool/release/trino-clickzetta-402.zip)，将插件解压到 Trino 安装目录下的 `plugin` 文件夹中。
+3.  下载 Trino-Clickzetta 插件配置文件。访问 [配置文件下载页面](https://autolake-dev-beijing.oss-cn-beijing.aliyuncs.com/clickzetta-tool/release/cziceberg.properties)，将配置文件复制到 Trino 安装目录下的 `etc/catalog` 文件夹中。根据您的实际情况，修改配置文件中的以下三项：
+   ```
+   iceberg.cz.uri=jdbc:clickzetta://instance.api.clickzetta.com/workspace?schema=public&vcluster=default
+   iceberg.cz.user=username
+   iceberg.cz.password=password
+   ```
+4.  启动或重启 Trino 服务。在 Trino 安装目录下执行以下命令：
+   ```shell
+   bin/launcher start/restart
+   ```
+
+## 使用 Trino Clickzetta 插件
+
+1. 使用 Trino 客户端连接至 Trino 服务器。您可以下载 [Trino 客户端](https://repo1.maven.org/maven2/io/trino/trino-cli/402/trino-cli-402-executable.jar)，并参考 [客户端使用指南](https://trino.io/docs/current/client/cli.html) 进行操作。
+
+   ```shell
+   java -jar trino-cli-402-executable.jar --server localhost:8080 --catalog cziceberg --schema public
+   ```
+
+2. 在 Trino 客户端中，执行以下命令查看 Clickzetta Lakehouse 中的表：
+
+   ```sql
+   show tables;
+   ```
+
+   您将看到类似于以下的表列表：
+
+   ```
+           Table
+   ----------------------------
+   lh_smoke_test_bulkload
+   lh_smoke_test_igs
+   spark_src
+   spark_src_complex_type
+   spark_srcpart
+   spark_srcpart_complex_type
+   spark_srcpart_date
+   spark_srcpart_int
+   (8 rows)
+   ```
+
+3. 查询表中的数据。例如，查询 `lh_smoke_test_igs` 表中的记录总数：
+
+   ```sql
+   select count(*) from lh_smoke_test_igs;
+   ```
+
+   结果类似于：
+
+   ```
+   _col0
+   -------
+   100
+   ```
+
+## 注意事项
+
+1. 本插件仅针对 Trino 402 版本进行开发和验证。
+2. 目前插件仅支持从 Clickzetta Lakehouse 读取数据，不支持写入数据。
+3. 插件暂不支持读取在 Clickzetta Lakehouse 中被更新或删除过的表。
+4. 有关 Trino 配置文件的详细信息，请参阅 [Trino 官方文档](https://trino.io/docs/current/installation/deployment.html#configuration)。

+# 概述
+>**【预览发布】本功能当前处于公开预览发布阶段。**
+
+External Catalog 是 Lakehouse 中的一个安全对象，它映射了外部数据系统中的数据库，使得用户可以在 Lakehouse 中对该数据系统执行只读查询。通过 External Catalog，用户可以利用 Lakehouse 的查询能力访问和分析存储在外部数据库中的数据。
+
+# External Catalog使用场景
+* **统一元数据管理**：将多个数据源的元数据统一管理，简化数据治理。
+* **数据联邦查询**：使用 External Catalog，用户可以在不同的数据源之间进行联合查询，如同它们是同一个数据库内的数据一样。通过联邦查询，用户能够实时访问和分析存储在外部系统中的数据，无需等待数据同步。
+* **数据导入**：将分散在不同数据源的数据导入 Lakehouse，构建统一的数据湖，便于进行大数据分析和机器学习。将历史数据或不常访问的数据保留在外部存储中，通过 External Catalog 导入到 Lakehouse，优化数据仓库的存储和性能。
+
+# 使用 External Catalog
+
+1. **创建连接**：首先，需要在 Catalog Connection 中创建一个连接（connection），这个连接是一个安全对象，它指定了用于访问外部数据库系统的路径和认证信息。
+2. **创建外部目录**：使用已创建的连接，可以创建一个外部目录（External Catalog）。这个目录在 Lakehouse 中作为安全对象存在，镜像了外部数据系统中的数据库结构。
+3. **执行查询**：一旦外部目录被创建，用户就可以在Lakehouse中编写 SQL 查询。
+
+# 支持的数据源
+
+Lakehouse 通过多源数据目录（Multi-Catalog）功能，
+- 支持了[Apache Hive连接访问](<create-hive-catalog.md>)
+- 支持External Iceberg Rest Catalog,具体参考[利用 External Catalog 访问 Snowflake OpenCatalog 的 Iceberg 表](<Query_SnowflakeOpenCatalog_Icebergtable.md>)
+- 支持访问Databricks,具体参考[Databricks-云器Lakehouse 跨平台数据联邦最佳实践指南](<databricks_yunqi_integration_guide_v2.md>)
+
+
+# EXTERNAL CATALOG相关使用语法
+- 创建External Catalog
+[参考CREATE EXTERNAL CATALOG](<create-external-catalog.md>)
+- 列出 Catalog
+[参考SHOW CATALOG](<show-catalog.md>)
+- 查看Catalog下的SCHEMA
+参考[查看EXTERNAL CATALOG下的SCHEMA](<show-catalog-schema.md>)
+- 列出CATALOG下的表
+参考[列出CATALOG下的表](<show-catalog-table.md>)
+- 查寻CATALOG下的表
+参考[查询CATALOG下的表](<show-catalog-table.md>)
+- 创建CATALOG下的表结构
+参考[查看CATALOG下的表结构](<desc-catalog-table.md>)
+
+# 权限
+目前创建的 Catalog 只有 instance admin 角色可以查询。
+# 使用案例
+[参考创建HIVE CATALOG](<create-hive-catalog.md>)

+# HUDI外部表
+>**【预览发布】本功能当前处于公开预览发布阶段。**
+
+HUDI为数据湖中的数据引入了结构化存储层，极大地提升了数据湖的易用性，使其操作体验接近于数据仓库。通过Lakehouse支持的外部表功能，用户能够便捷地访问和操作这些结构化数据。
+
+## 创建HUDI格式外部表
+
+\[创建外部表语法]\(create-external-table.md)
+
+**示例**
+
+```SQL
+--创建conneciton
+CREATE STORAGE CONNECTION if not exists oss_hudi
+    TYPE oss
+    ENDPOINT = 'oss-cn-beijing.aliyuncs.com'
+    access_id = 'xxx'
+    access_key = 'xxxx'
+    comments = 'hudi';
+--创建外部表,使用上面的连接信息
+CREATE EXTERNAL TABLE IF NOT EXISTS sales_data
+(
+  order_id INT,
+  product_id STRING,
+  sale_amount DOUBLE
+)
+PARTITIONED BY (dt STRING)
+USING HUDI
+CONNECTION oss_hudi
+LOCATION 'oss://my-bucket/data/sales'
+COMMENT 'External table for sales data stored in OSS';
+```
+
+## 删除外部表
+
+```SQL
+DROP TABLE [ IF EXISTS ] [schema_name.]<table_name
+```
+
+**参数说明**
+
+* `IF EXISTS`：可选，如果指定的表不存在，系统不会报错。
+* `schema_name`：可选，指定 schema 的名称。如果未指定，默认使用当前用户的 schema。
+* `table_name`：要删除的表名称。
+
+**说明**
+
+* 删除外部表并不会删除数据，因为数据存储在外部系统中，删除操作只会删除表的映射信息。
+
+**示例**
+
+```SQL
+--删除已经创建的外部表
+DROP TABLE sales_data;
+--删除名为 sales_data 的表，如果表不存在，不报错：
+DROP TABLE IF EXISTS sales_data;
+--删除名为 my_schema 下的 sales_data表
+DROP TABLE my_schema.my_table;
+```
+
+## 查看外部表详情
+
+```SQL
+DESC[RIBE] [TABLE] [EXTENDED] table_name;
+```
+
+**参数说明**
+
+* **DESC\\\[RIBE]**：DESC和DESCRIBE可以互换使用，都表示描述表结构的命令。
+* **TABLE**：可选参数，用于指定查看表结构的类型，如BASE TABLE或VIEW等。
+* **EXTENDED**：可选参数，加入此关键字后，可以展示更多扩展信息，如表的创建语句和Location信息等。
+* **table\\\_name**：指定需要查看结构的表名。
+
+## 修改外部表
+
+### 重命名表
+
+通过ALTER TABLE命令，您可以将现有的表重命名为新的表名。
+
+**语法**
+
+```SQL
+ALTER TABLE name RENAME TO new_table_name;
+```
+
+**示例**
+
+```SQL
+ALTER TABLE old_table_name RENAME TO new_table_name;
+```
+
+### 修改表注释
+
+通过ALTER TABLE命令，您可以为表添加或修改注释。
+
+**语法**
+
+```SQL
+ALTER TABLE tbname SET COMMENT '';
+```
+
+**示例**
+
+```SQL
+ALTER TABLE scores SET COMMENT '这是一个成绩表';
+```
+
+## **外部表计费**
+
+* **存储费用**：外部表不产生存储费用，因为数据不存储在 Lakehouse 中。
+* **计算费用**：使用外部表进行计算会消耗计算资源，因此会产生计算费用。
+
+## **外部表权限**
+
+外部表和内部表权限点相同。由于外部表无法执行 INSERT、UPDATE、TRUNCATE、DELETE、UNDROP 等操作，因此没有对应的操作权限点。
+
+* **创建权限**：需要具有创建表（create table）的权限。
+* **删除权限**：需要具有删除（DROP）权限。
+* **读取权限**：需要具有选择（select）权限。
+
+## **使用注意事项**
+
+* **连接配置**： 创建 connection 时，确保 endpoint 配置正确，以便 Lakehouse 能够成功连接。如果 Lakehouse 和对象存储位于同一云服务且在同一区域，通常使用内网地址即可实现网络互通。如果不在同一网络环境，建议使用对象存储的公网地址。
+
+## 具体案例
+
+### 连接阿里云Oss
+
+```SQL
+--创建connection,用于连接对象存储
+CREATE STORAGE CONNECTION  oss_hudi
+    TYPE oss
+    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com'
+    access_id = 'xxxxxx'
+    access_key = 'xxxxxx'
+    comments = 'hudi'
+    ;
+--使用上面的链接信息，创建外部表
+CREATE    EXTERNAL TABLE pepole_hudi (id int, name string,dt string) 
+USING HUDI 
+CONNECTION oss_hudi 
+PARTITIONED BY (dt ) 
+LOCATION 'oss://bucketmy/hudi-format/uploadhudi/' 
+COMMENT 'external';
+```
+
+### 连接Google GCS
+
+Lakehouse 连接 Google Cloud Storage (GCS) 时，将使用服务账号密钥进行身份验证。请按照以下步骤操作：
+
+1. **获取服务账号密钥**：
+
+* 登录 Google Cloud 控制台。
+* 按照 *[Google Cloud 文档](https://cloud.google.com/docs/authentication/getting-started)* 的指导，创建并下载服务账号的 JSON 密钥文件。
+
+2. **配置 ****`private_key`**** 参数**：
+
+* 打开下载的 JSON 密钥文件，将文件中的私钥内容完整复制
+
+3. **注意**：
+
+* 在配置 `private_key` 时，必须前面添加r,r代表区分大小写，殊字符和 unicode 字符都不会被转义。
+
+```SQL
+--创建connection,用于连接对象存储
+CREATE STORAGE CONNECTION  oss_hudi
+    TYPE gcs
+    private_key=r'{
+  "type": "service_account",
+  "project_id": "PROJECT_ID",

+# **外部表简介**
+
+**功能概述：** 外部表是 Lakehouse 的一项特性，它使您能够查询存储在外部系统中的数据，就如同这些数据存储在 Lakehouse 内部一样。这些外部数据并不存储或管理在 Lakehouse 中。
+
+**性能提示：** 由于外部表中的数据存储在 Lakehouse 外部，查询外部表可能比查询存储在本地的表稍慢。为了提升查询效率，建议使用 `INSERT INTO internal_table_name SELECT * FROM external_table_name` 语句或 `COPY INTO` 命令将数据导入到 Lakehouse 中。
+
+## 支持的外部表数据源
+- Kafka 外部表
+- Delta Lake 外部表
+- Hudi 外部表
+## **外部表与 External Schema 的区别**
+
+* **External Schema：** 直接与 Hive 元数据服务（HMS）交互，通过 HMS 接口直接获取 Hive 的元数据信息。
+* **外部表：** 允许用户自定义创建表，指定列内容和表名。
+* **External Schema 限制：** 由于是直接映射 HMS，无法在 External Schema 下直接创建、删除表或重命名表。
+* **外部表优势：** 支持重命名和修改注释等操作，因为它们是在内部 schema 下创建的。

+```
+
+### **3.2 外部Schema配置**
+
+```SQL
+-- 创建映射hive中的databse
+CREATE EXTERNAL SCHEMA external_db_schema 
+CONNECTION hive_catalog 
+OPTIONS ( 'schema'='default');
+```
+
+### **3.3 外部表配置**
+
+```SQL
+-- 创建Delta Lake外部表
+CREATE EXTERNAL TABLE delta_sales
+USING DELTA 
+CONNECTION oss_delta 
+LOCATION 'oss://bucketname/delta-format/sales/' 
+COMMENT 'Delta外部表示例';
+
+-- 创建Kafka外部表
+CREATE EXTERNAL TABLE kafka_messages (
+  key STRING,
+  value STRING,
+  topic STRING,
+  partition INT,
+  offset BIGINT,
+  timestamp BIGINT
+)
+USING KAFKA
+CONNECTION kafka_conn
+OPTIONS (
+  'kafka.bootstrap.servers' = 'broker:9092',
+  'subscribe' = 'test-topic'
+);
+```
+
+## **4. 查询使用**
+
+### **4.1 查询外部Catalog中的表**
+
+```SQL
+-- 使用三层语法查询外部Catalog中的表
+SELECT * FROM databricks_catalog.default.sales 
+WHERE region = 'APAC'
+LIMIT 10;
+
+-- 关联查询外部Catalog和内部表
+SELECT a.customer_id, a.order_total, b.customer_name
+FROM databricks_catalog.sales.orders a
+JOIN internal_schema.customers b
+ON a.customer_id = b.id
+WHERE a.order_date >= '2024-01-01';
+```
+
+### **4.2 查询外部Schema中的表**
+
+```SQL
+-- 查询外部Schema中的表
+SELECT * FROM external_db_schema.customer_table
+WHERE register_date > '2023-01-01';
+```
+
+### **4.3 查询外部表**
+
+```SQL
+-- 查询Delta外部表
+SELECT product, SUM(price) as total_sales
+FROM delta_sales
+WHERE sale_date BETWEEN '2024-01-01' AND '2024-04-30'
+GROUP BY product
+ORDER BY total_sales DESC;
+
+-- 查询Kafka外部表
+SELECT * FROM kafka_messages
+WHERE timestamp > 1715132800000 -- 2024-05-08 00:00:00 UTC
+LIMIT 100;
+```
+
+## **5. 性能优化最佳实践**
+
+### **5.1 数据导入策略**
+
+由于外部表中的数据存储在Lakehouse外部，查询性能可能不如内部表。对于频繁查询的数据，建议导入到内部表：
+
+```SQL
+-- 将外部表数据导入内部表
+INSERT INTO internal_sales_table 
+SELECT * FROM databricks_catalog.sales.orders
+WHERE order_date >= '2024-01-01';
+
+```
+
+### **5.2 分区和筛选**
+
+利用分区信息和筛选条件减少数据扫描量：
+
+```SQL
+-- 使用分区筛选
+SELECT * FROM delta_sales
+WHERE sale_date = '2024-05-15'  -- 此处使用分区字段可大幅提升性能
+AND product = 'Laptop';
+```
+
+## **6. 管理和监控**
+
+### **6.1 查看外部对象**
+
+```SQL
+-- 查看所有Catalog
+SHOW CATALOGS;
+
+-- 查看所有外部Schema
+SHOW SCHEMAS EXTENDED WHERE type='external';
+
+-- 查看外部Schema中的表
+SHOW TABLES IN external_db_schema;
+
+-- 检查外部表结构
+DESCRIBE TABLE delta_sales;
+```
+
+## **7. 典型案例**
+
+### **7.1 数据湖与数据仓库统一查询**
+
+场景：企业同时拥有Hive数据湖和Databricks数据仓库，需要进行跨平台分析。
+
+解决方案：
+
+1. 创建连接到Hive和Databricks的外部Catalog

+# 任务调度和实例执行方式
+
+## 概要说明
+
+### 概念说明
+
+在任务开发场景中，离线任务都是周期性的运行（比如一天多次，一天一次等），除此之外，任务之间往往还会存在上下游的依赖关系，并按照依赖依次执行。像这种周期性的、有任务上下游依赖关系的就是调度的核心概念。
+
+### 任务与实例
+
+当用户在开发中，将一个开发脚本提交至生产环境后，即生成一个周期任务。一个周期任务每运行一次，就会生成一个周期实例，每个周期实例中可能会包含多次执行记录，例如自动重跑。
+
+因此，周期任务与周期实例往往是一对多的关系。
+
+## 调度系统的运作规则
+
+调度系统的任务主要是两方面：**生成实例**和**按计划运行实例**。具体概念如下：
+
+### 生成实例
+
+当任务提交到调度系统后，系统会根据调度配置的信息来生成实例。当前系统内提供两种生成实例的方式：
+
+* 次日生效：当日晚上22:00统一生成第二天的所有需要执行的实例。
+* 发布后立刻生效：即从用户点击提交后，系统会立即生成当天需要立即执行的实例。第二天的实例则按照系统默认的方式在晚上22:00统一生成。
+
+具体生成规则，在调度属性配置「实例生成」中详细介绍。
+
+### 按计划运行运行实例
+
+每天按计划运行实例时，调度系统判断一个实例是否可以运行，一般情况下需要满足两个条件：
+
+* 任务是否到达了计划时间
+* 上游任务是否全部成功
+
+^
+
+若满足了以上两个条件，调度系统就会将该实例任务提交执行。当该实例任务获取到相应的资源后就会正常的如期执行**实例运行**。
+
+若不能满足以上两个条件，任务实例会处于**未开始**的状态。但是为了避免任务实例因为配置或上游暂停等情况导致大批量的任务实例长期处于未开始的状态，导致资源浪费。系统会基于用户配置的「调度等待时长」执行kill操作，即该任务实例会被系统直接判定为失败状态。
+
+| 注意：  若生产环境中的周期任务未配置调度等待时长，则默认实例的调度等待时长为3天。即：当该任务到达了计划时间时，3天后无论上游任务是否全部成功，都会从**未开始**状态变更为**失败**状态。  若用户在调度配置中配置了「调度等待时长」，则待任务达到了计划时间时，无论上游任务是否全部成功，一旦超过了调度等待时长，任务实例状态均会从**未开始**状态变更为**失败**状态。 |
+| -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+
+## 调度属性配置
+
+在「开发」模块下，打开任意一个任务，点击调度配置功能，即可配置该任务的一系列调度属性信息。包括基础信息、调度时间、实例信息、调度依赖、任务产出等。
+
+*本文重点介绍*调度时间、实例信息、调度依赖，*其他内容可参考帮助文档*，
+
+### 调度时间
+
+![](.topwrite/assets/f6fc6447ee/b35ef5af588033e07f3e757c89edfd025ec25ca6.png =582)
+
+***
+
+**调度周期**：可配置调度周期、调度频次、开始调度时间、结束调度时间。当用户配置完这些信息后，系统会基于配置自动生成符合规则的标准cron表达式。自动生成该时间表达式会被调度引擎解析，通过时间轮算法推演出未来周期内所有符合条件的具体执行实例。
+
+当前系统内的调度频次有分钟、小时、天三种。如果一个任务的Cron表达式在天以上的位置，比如周，月，年等区域，设置了取值为单一值或多值（而不是\*）的，只要这些位置的取值不冲突，合法，那么不改变该任务的原有时间类型（不会变成周，月，年任务），只是约束了任务具体在哪些天跑，是这些天里的分钟，小时，天任务。（换句话说，其实没有周，月，年任务的概念）
+
+例如：
+
+* 每个月1号，3号，一个任务在指定时间跑一次，那就是一个日任务，而不是月任务
+* 每周1，和周3这两天里，一个任务每隔两小时跑一次，那就是一个小时任务，而不是周任务，也不是天任务
+* 分钟任务类似，当任务的间隔是分钟级别的，那就是一个分钟任务。
+
+***
+
+**生效日期**：指当前调度任务的调度生效日期范围。支持用户选择永不结束或者指定日期。
+
+永不结束即永久生效，目前系统是到2099年。
+
+若用户指定了日期，那么当超出生效日期后，此调度任务的实例不会再生成。
+
+####
+
+### 实例信息
+
+#### 实例生成
+
+![](.topwrite/assets/f6fc6447ee/9260e6641b50d8940c20836bfdb9330b4ba7eeab.png =556)
+
+**实例生成**：基于用户配置的**调度配置信息和依赖关系**，**按照用户选择的实例生成的规则生成相应的实例**。
+
+发布后生效：从提交任务后立刻生效，具体实例变更/生成范围是：
+
+* 提交时间 早于 调度开始时间，以调度开始时间开始，更新/生成后续的实例
+* 提交时间 晚于 调度开始时间，那么自提交发布时间后，会更新/生成相应的实例
+* 历史已生成的不影响，仅从起始时间开始向后变更后续的实例。
+
+![](.topwrite/assets/f6fc6447ee/94bccbdeead608afb473198307e1466cab001784.jpeg =757)
+
+次日生效：当日晚上22:00统一生成第二天的所有需要执行的实例：
+
+####
+
+#### 实例重跑方式
+
+![](.topwrite/assets/f6fc6447ee/6d2c0d8953eac7b7256337937f6f795fd084a154.png =522)
+
+产品内提供了三种重跑方式，主要会作用在以下两种场景的行为：
+
+* 实例运行失败后，是否由系统自动重跑。
+* 实例运行成功或失败后，是否运行用户在运维中心的实例运维列表下，点击重跑操作。
+
+***
+
+不同取值方式和行为定义如下：
+
+* **运行成功或失败，都可以重跑** ：选择这种方式后，还需额外设置「实例自动重跑次数」和「实例重跑时间间隔」。选择该行为后，当实例运行失败时，系统会基于配置的重跑次数和间隔，依此触发自动重跑，一旦运行成功或到达重跑约定次数后，不再触发自动重跑的能力。同时可以在运维中心中找到该实例，无论该实例的状态时成功还是失败，均支持用户手动点击重跑操作，触发重跑行为。
+* **运行失败可以重跑，运行成功不可以重跑**：具体行为同上，唯一区别在于。在运维中心操作时，若该实例的状态是成功的，则不允许点击重跑操作。
+* **运行成功或失败，都不可以重跑**：选择该方式后，不会触发自动重跑行为，同时也不允许用户在运维中心点击重跑操作。
+
+#### 运行超时时长
+
+![](.topwrite/assets/f6fc6447ee/e99998089947ef23c63b79f948c107be37e9cac6.png =602)
+
+当用户配置了运行超时时长时，若该任务实例运行时间超过设置的时间后会被强制kill，运行状态变更为失败。目的是当一个任务长时间处于「运行中」状态时，会导致资源的占用，通过设置“超时时间”，可以及时释放资源。
+
+#### 调度等待时长
+
+![](.topwrite/assets/f6fc6447ee/7eb115526d02c946b30b1b2b9d78730794eb5d85.png =619)
+
+配置调度等待时长后，当任务实例到达计划运行时间后，无论上游是否成功执行均会触发强制kill的行为。该配置主要用于上游任务因暂停导致大批量下游实例无法执行导致的资源浪费，建议谨慎配置。
+
+### 调度依赖
+
+调度依赖是指周期调度节点间的上下游依赖关系。通过节点的依赖关系有序调度运行上下游节点，即当上游节点运行成功后，下游节点才会启动运行，保障适时的产出有效业务数据。
+
+更多调度依赖相关的实例执行行为见：[任务调度依赖关系](task_scheduling_dependency.md)
+
+## 运维操作
+
+### 周期任务
+
+* **暂停**：周期任务中状态是「正在调度」的可支持点击暂停。点击暂停后，自当前触发开始往后的所有实例任务均会被置为「暂停」。所有实例的概念包括：当天已生成的且未运行的实例，以及每天22点生成的第二天的所有实例。即虽然用户点击了暂停操作，但是仅是操作了实例的状态，并不阻塞该任务按期生成实例的行为。暂停行为仅是将该周期任务中的实例置为暂停状态，下游状态通常情况下会收到暂停的任务阻塞而导致无法运行。但是若下游任务配置了调度等待时长（或下游任务的自计划开始运行开始调度等待时长超过3天），那么下游任务会被强制kill。
+* **启动**：周期任务中状态是「暂停调度」的可支持点击启动。点击启动后，当前周期任务中所有暂停的实例均会触发执行的行为。
+* **下线**：周期任务直接下线后，在周期任务中不会进行任务管理，同时也不会再生成实例。若当前任务有下游任务正在运行，则不允许直接下线。需先将下游任务下线后，或点击下线（含下游）任务将当前任务即下游全部下线。
+* **补数**：无论周期任务的状态是什么，均支持用户点击补数操作。用户触发补数行为后，会在补数任务中生成一个对应的补数任务。
+
+^
+
+### 实例运维
+
+* **重跑**：只有执行结束的周期实例才可以操作重跑功能。且不同状态是否能重跑取决于用户在调度配置中的具体选项。若用户配置了 **运行成功或失败，都不可以重跑**，则也不允许点击重跑。用户在重跑操作上支持选择跑当前节点，或下游节点的能力。若用户有代码调整，并希望将某个节点按照最新代码重跑，则可以勾选使用最新代码和配置的能力，直接执行重跑操作。
+* **暂停**：对于处于非暂停状态的任务实例才可操作。操作后，会把任务实例的调度属性设置为“暂停调度”，即不再调度运行该任务实例。
+* **恢复**：对于处于暂停状态的任务实例才可操作。操作后，会把任务实例的调度属性恢复为“正常调度”，即按照设定的调度时间来运行任务实例。
+* **终止**：对于运行中的任务实例才可以操作。操作后，会终止任务实例的运行、把任务实例状态置为失败。
+* **置成功**：对于运行失败的任务实例才可以操作。操作后，强制将该任务实例置为成功。可用于紧急运维场景，在判断当前任务实例即使失败，也不影响下游任务的数据正确性的前提下，解除对下游任务实例运行的阻塞。
+* **置失败**：对于运行成功的任务实例才可以操作。操作后，强制将该任务实例置为失败。

+帆软BI（FineBI） 是帆软软件有限公司推出的一款商业智能（Business Intelligence）产品。FineBI 是新一代大数据分析的 BI 工具，旨在帮助企业的业务人员充分了解和利用他们的数据。本文介绍使用Mysql协议来连接Lakehouse
+
+# 准备工作
+
+* 请参考[FineBI官网](https://www.finebi.com/)，如果已经安装完毕请跳过。
+
+* 使用Mysql协议连接。目前需要重置密码，即使是新建的账号也需要重置密码。这是因为 MySQL 5.x 版本使用的是 `mysql_native_password` 密钥，而 Lakehouse 需要保存 MySQL 的加密算法。目前，只有在修改密码时，Lakehouse 才会保存 MySQL 密钥的加密算法。您可以修改密码时保持和之前一样这样可以避免影响别的任务连接
+
+* 给用户设置计算集群，由于 MySQL 协议中没有传入设置集群的方式，用户可以使用 SQL 命令为用户添加一个默认计算集群。这样在 MySQL 连接时就会使用该集群。
+
+  * ```SQL
+    ALTER USER user_name SET DEFAULT_VCLUSTER = default;-- 查看集群设置是否生效SHOW USERS;
+    ```
+
+* 准备用户名。 MySQL 协议连接地址时只能传入一个URL无法拼接Lakehouse的instace name和worksapce name,因此需要将。instace name和worksapce name拼接到用户名中
+
+  *   用户名格式要求如下：
+
+  * ```Plain
+    登录的账号名称@instance_name.workspace_name
+    ```
+
+  * **instance\_name 获取**：在 工作空间页面 中获取 JDBC 连接串。例如，在 `jdbc:clickzetta://``jnsxwfyr.api.clickzetta.com/quick_start?virtualCluster=default` 中，`jnsxwfyr` 为 instance\_name。
+  * **workspace\_name 获取**：工作空间的名称。

+# 功能简介
+
+Lakehouse 通过 flink-connector-lakehouse 插件，实现了与 Flink 的无缝对接，使得数据能够高效地写入 Lakehouse。该插件采用实时接口进行数据写入，确保了数据处理的时效性。
+
+Lakehouse 提供了两种 Flink Connector 写入模式：igs-dynamic-table 和 igs-dynamic-table-append-only，以满足不同场景下的需求。
+
+1. **igs-dynamic-table**：支持追加模式和Flink CDC场景。在这种模式下，当 Flink 作为数据源接入 CDC 日志时，如果源端包含 update、delete 及 insert 操作，并且 Lakehouse 服务端表设置了主键属性，使用 igs-dynamic-table 将触发数据的更新和删除操作。支持在Lakehouse中[主键表](primary-key.md)写入。
+2. **igs-dynamic-table-append-only**：特别适用于不希望进行数据更新或删除的场景。即使在 Flink CDC 同步数据时，该模式也能确保数据仅进行追加操作，避免了不必要的数据变更。如果您的目标是避免数据的删除和更新，选择 igs-dynamic-table-append-only 将是一个更安全的选择。这样，您的数据将始终保持原始状态，不会被后续操作所影响。支持Lakehouse普通表写入。
+
+| **类别** | **详情**            |
+| ------ | ----------------- |
+| 支持的类型  | 只支持结果表，不支持作为源表和维表 |
+| 运行模式   | 流模式               |

+
+## 使用方法
+
+### TABLE API方式写入
+
+```Java
+-- First, define your data source
+CREATE TABLE source_table (
+  col1 INT,
+  col2 INT,
+  col3 VARCHAR
+) WITH (
+  'connector' = 'your-source-connector',
+  'property1' = 'value1'
+);
+
+-- Second, define IGS table sink
+CREATE TABLE mock_table (
+  col1 INT,
+  col2 INT,
+  col3 VARCHAR
+) WITH (
+  'connector' = 'igs-dynamic-table',
+  'curl' = 'jdbc:clickzetta://{instance-name}.{regin}.api.clickzetta.com/default?username=user&password=******&schema=public',
+  'schema-name' = 'public',
+  'table-name' = 'mock_table',
+  'sink.parallelism' = '1',
+  'properties' = 'authentication:true'
+);
+
+-- Third, execute the data transfer
+INSERT INTO mock_table
+SELECT * FROM source_table;
+```

+## 实时数据同步：使用Flink CDC将MySQL数据写入Lakehouse主键表
+
+### 概述
+
+本文详细介绍了如何通过Lakehouse的flink connector使用igs-dynamic-table模式，实现MySQL数据库的变更数据捕获（CDC）日志实时同步到Lakehouse的主键表中。在igs-dynamic-table模式下，Lakehouse主键列的数据能够自动更新，确保数据的一致性和实时性。
+
+### STEP 1:环境准备
+
+* 使用IntelliJ IDEA作为开发工具，需具备Flink编程能力。
+* 获取Lakehouse连接信息，可在Lakehouse Studio管理 -> 工作空间中查看JDBC连接串，如下：
+![](../.topwrite/assets/image_1728887857029.png)
+
+```SQL
+jdbc:clickzetta://6861c888.cn-shanghai-alicloud.api.clickzetta.com/quickstart_ws?username=xxx&password=xxx&schema=public
+```
+
+* 本地搭建的Mysql数据库
+
+* 下载Lakehouse提供的Flink Connector包（目前由Lakehouse支持提供下载包），下载完成后将JAR包打入到本地Maven仓库中，方便在Maven项目中引用和打包。
+
+  * ```SQL
+    mvn install:install-file -Dfile=igs-flink-connector-15-0.11.0-shaded.jar -DgroupId=com.clickzetta -DartifactId=igs-flink-connector-15 -Dversion=0.11.0 -Dpackaging=jar
+    ```
+
+* 修改pom.xml文件，添加如下依赖
+
+  * ```XML

+
+### STEP 2:在Mysql中创建表并插入测试数据
+
+```SQL
+create table people (id int primary key,name varchar(100));
+insert into people values(1,'a'),(2,'b'),(3,'c');
+```
+
+### STEP 3:在Lakehouse中创建主键表
+
+```SQL
+create table people (id int,name string,primary key(id));
+```
+
+Lakehouse的**主键（PRIMARY KEY）** 用于确保表中每条记录的唯一性。在Lakehouse架构中，定义了主键的表在进行实时数据写入时，系统将自动根据主键值进行数据去重，一旦设置了主键，您将无法通过SQL语句执行插入、删除、更新操作，也不能添加或删除列。
+
+### STEP 4:编写代码,并在IDEA启动任务
+
+```SQL
+import org.apache.flink.api.common.restartstrategy.RestartStrategies;
+import org.apache.flink.api.common.time.Time;
+import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment;

+public class MysqlCDCToLakehouse {
+    public static void main(String[] args) throws ExecutionException, InterruptedException {
+
+        StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment()
+                .setParallelism(1);
+        env.setRestartStrategy(RestartStrategies.fixedDelayRestart(100, Time.seconds(60)));
+        //      env.enableCheckpointing(60000);
+//
+//
+//        env.getCheckpointConfig().setCheckpointingMode(CheckpointingMode.EXACTLY_ONCE);
+//
+//        env.getCheckpointConfig().setMinPauseBetweenCheckpoints(1000);
+
+// checkpoint 必须在 60s 内结束，否则被丢弃，默认是 10 分钟
+//        env.getCheckpointConfig().setCheckpointTimeout(60000);
+// 同一时间只能允许有一个 checkpoint
+//        env.getCheckpointConfig().setMaxConcurrentCheckpoints(1);
+// 最多允许 checkpoint 失败 3 次
+//        env.getCheckpointConfig().setTolerableCheckpointFailureNumber(3);
+// 当 Flink 任务取消时，保留外部保存的 checkpoint 信息
+//        env.getCheckpointConfig().enableExternalizedCheckpoints(CheckpointConfig.ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);
+        StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env);
+        String mysqlCdc ="create table mysql_people(\n" +

+
+        tableEnv.executeSql(mysqlCdc);
+
+        // 字段个数需要保持和lakehouse表一致
+        String lakehouseTable ="create table lakehouse_people(\n" +

+        tableResult.await();
+
+    }
+}
+```
+
+### STEP 5:数据同步验证
+
+* 启动完成后将会将mysql数据自动同步到lakehouse中，在Lakehouse中查询数据
+
+```SQL
+select * from people;
++----+------+
+| id | name |
++----+------+
+| 2  | b    |
+| 3  | c    |
+| 1  | a    |
++----+------+
+```
+
+* 在mysql更新一条数据
+
+```SQL
+update people set name='A' where id=1;
+```
+
+* 在Lakehouse中查询，则会保持和mysql数据一致
+
+```SQL
+select * from people;
++----+------+
+| id | name |
++----+------+
+| 2  | b    |
+| 3  | c    |
+| 1  | A    |
++----+------+
+```
+
+## 实时数据同步：使用Flink CDC将MySQL数据写入Lakehouse普通表中
+
+### 概述
+
+本文详细介绍了如何通过Lakehouse的flink connector使用igs-dynamic-table-append-only模式，实现MySQL数据库的变更数据捕获（CDC）日志实时同步到Lakehouse的普通表中。在igs-dynamic-table-append-only模式下，Lakehouse 将直接记录 CDC 原始日志，而不会更新Lakehouse中的数据。
+
+### STEP 1:环境准备
+
+* 使用IntelliJ IDEA作为开发工具，需具备Flink编程能力。
+* 获取Lakehouse连接信息，可在Lakehouse Studio管理 -> 工作空间中查看JDBC连接串，并将JDBC协议替换为igs。如下修改为：

+
+```SQL
+jdbc:clickzetta://6861c888.cn-shanghai-alicloud.api.clickzetta.com/quickstart_ws?username=xxx&password=xxx&schema=public
+```
+
+* 本地搭建的Mysql数据库
+
+* 下载Lakehouse提供的Flink Connector包（目前由Lakehouse支持提供下载包），下载完成后将JAR包打入到本地Maven仓库中，方便在Maven项目中引用和打包。
+
+  * ```SQL
+    mvn install:install-file -Dfile=igs-flink-connector-15-0.11.0-shaded.jar -DgroupId=com.clickzetta -DartifactId=igs-flink-connector-15 -Dversion=0.11.0 -Dpackaging=jar
+    ```
+
+* 修改pom.xml文件，添加如下依赖

+
+### STEP 2:在Mysql中创建表并插入测试数据
+
+```SQL
+create table people_append (id int primary key,name varchar(100));
+insert into people_append values(1,'a'),(2,'b'),(3,'c');
+```
+
+### STEP 3:在Lakehouse中创建普通表
+
+```SQL
+create table people_append (id int,name string,source_operate string);
+```
+
+`source_operate` 字段用于记录 MySQL 中的日志操作。在 Lakehouse Flink Connector 中配置 `mapping.operation.type.to`，可以指定 CDC 的操作符落入 Lakehouse 表中的字段名。
+
+### STEP 4:编写代码,并在IDEA启动任务
+
+```SQL

+
+        StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment()
+                .setParallelism(1);
+        env.setRestartStrategy(RestartStrategies.fixedDelayRestart(100, Time.seconds(60)));
+        //      env.enableCheckpointing(60000);
+//
+//
+//        env.getCheckpointConfig().setCheckpointingMode(CheckpointingMode.EXACTLY_ONCE);
+//
+//        env.getCheckpointConfig().setMinPauseBetweenCheckpoints(1000);
+
+// checkpoint 必须在 60s 内结束，否则被丢弃，默认是 10 分钟
+//        env.getCheckpointConfig().setCheckpointTimeout(60000);
+// 同一时间只能允许有一个 checkpoint
+//        env.getCheckpointConfig().setMaxConcurrentCheckpoints(1);
+// 最多允许 checkpoint 失败 3 次
+//        env.getCheckpointConfig().setTolerableCheckpointFailureNumber(3);
+// 当 Flink 任务取消时，保留外部保存的 checkpoint 信息
+//        env.getCheckpointConfig().enableExternalizedCheckpoints(CheckpointConfig.ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);
+        StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env);

+        tableResult.await();
+
+    }
+}
+```
+
+### STEP 5:数据同步验证
+
+* 启动完成后将会将mysql数据自动同步到lakehouse中，在Lakehouse中查询数据
+
+```SQL
+select * from people;
++----+------+
+| id | name |
++----+------+
+| 2  | b    |
+| 3  | c    |
+| 1  | a    |
++----+------+
+```
+
+* 在mysql更新一条数据
+
+```SQL
+update people set name='A' where id=1;
+```
+
+* 在Lakehouse中查询，则会保持记录mysql的所有操作
+
+```SQL
++----+------+----------------+
+| id | name | source_operate |
++----+------+----------------+
+| 1  | a    | INSERT         |
+| 2  | b    | INSERT         |
+| 3  | c    | INSERT         |
+| 1  | a    | UPDATE_BEFORE  |
+| 1  | A    | UPDATE_AFTER   |
++----+------+----------------+
+```

+# Lakehouse 全文检索使用指南
+
+***
+
+## 附录 写在前面
+
+## 附录# 您可能遇到的文本检索场景
+
+## 附录## 附录 场景1：企业知识库搜索系统
+
+**当前在Hive/Spark中的常见做法**：
+
+```sql
+-- 在Hive中进行文本搜索
+SELECT * FROM knowledge_base 
+WHERE content LIKE '%人工智能%' 
+   OR content LIKE '%机器学习%' 
+   OR content LIKE '%深度学习%';
+
+-- 性能问题：
+-- 1. 全表扫描，无法利用索引
+-- 2. 只能精确匹配，无法进行语义搜索
+-- 3. 中文分词困难，搜索效果差
+```
+
+**面临的技术挑战**：
+
+* **性能限制**：LIKE查询需要全表扫描，大数据量时性能极差
+* **功能局限**：无法进行分词搜索，只能精确字符串匹配
+* **维护复杂**：需要手动管理搜索关键词和同义词
+* **扩展困难**：多语言支持需要额外开发
+
+## 附录## 附录 场景2：日志分析与故障排查
+
+**在Elasticsearch中的典型实现**：
+
+```javascript
+// Elasticsearch查询
+{
+  "query": {
+    "multi_match": {
+      "query": "ERROR timeout connection",
+      "fields": ["message", "stack_trace"]
+    }
+  }
+}
+```
+
+**常见的技术痛点**：
+
+* **架构复杂**：需要维护独立的搜索引擎系统
+* **数据同步**：数据需要从数据湖同步到搜索引擎
+* **成本问题**：额外的存储和计算资源消耗
+* **一致性风险**：数据同步延迟导致搜索结果不准确
+
+## 附录# 为什么需要原生全文检索
+
+基于以上场景中的技术挑战，Lakehouse原生全文检索的设计目标是：
+
+**统一的数据处理平台**：
+
+* 在同一系统中完成分析计算和全文检索
+* 无需维护独立的搜索引擎系统
+* 数据存储和检索的强一致性
+
+**高性能的倒排索引**：
+
+* 基于倒排索引的快速文本检索
+* 支持多种分词策略和语言
+* 比传统LIKE查询性能提升数十倍
+
+**智能的分词和匹配**：
+
+* 支持中文、英文、Unicode等多种分词器
+* 提供短语匹配、前缀匹配、正则匹配等多种模式
+* 自动大小写转换和标点符号过滤
+

+
+| 读者角色  | 建议阅读重点             | 预期收获           |
+| ----- | ------------------ | -------------- |
+| 数据工程师 | 索引创建 → 函数使用 → 性能优化 | 掌握倒排索引的正确使用方法  |
+| 系统架构师 | 应用场景 → 架构对比 → 迁移策略 | 获得从传统搜索引擎的迁移指导 |
+| 应用开发者 | 快速开始 → 查询模式 → 避坑指南 | 了解全文检索的最佳实践    |
+
+***
+
+## 附录 快速开始
+
+## 附录# 基本使用流程
+
+```sql
+-- 1. 创建包含倒排索引的表
+CREATE TABLE documents (
+    id BIGINT,
+    title STRING,
+    content STRING,
+    created_at TIMESTAMP,
+    
+    -- 建表时定义倒排索引
+    INDEX title_idx (title) INVERTED PROPERTIES('analyzer'='keyword'),
+    INDEX content_idx (content) INVERTED PROPERTIES('analyzer'='chinese', 'mode'='smart')
+);
+
+-- 2. 插入数据
+INSERT INTO documents VALUES 
+(1, 'ClickZetta技术指南', '云器Lakehouse支持向量检索和全文搜索功能', CURRENT_TIMESTAMP());
+
+-- 3. 为已有数据构建索引
+BUILD INDEX content_idx ON documents;
+
+-- 4. 执行全文检索查询
+SELECT id, title FROM documents 
+WHERE MATCH_ANY(content, '全文搜索 向量检索', map('analyzer', 'auto'));
+
+-- 5. 使用短语匹配
+SELECT id, title FROM documents 
+WHERE MATCH_PHRASE(content, '全文搜索功能', map('analyzer', 'auto'));
+```
+
+***
+
+## 附录 技术对比：传统方案 vs 原生全文检索
+
+## 附录# 传统LIKE查询方案
+
+```sql
+-- 使用LIKE进行文本搜索
+SELECT * FROM documents 
+WHERE content LIKE '%人工智能%' 
+   OR content LIKE '%机器学习%'
+   OR content LIKE '%深度学习%';
+
+-- 存在的问题：
+-- 1. 全表扫描，性能差
+-- 2. 无法分词，只能精确匹配
+-- 3. 大小写敏感
+-- 4. 无法处理同义词
+```
+
+## 附录# 外部搜索引擎方案
+
+```yaml
+# 需要维护额外的Elasticsearch集群
+version: '3'
+services:
+  elasticsearch:
+    image: elasticsearch:7.14.0
+    environment:
+      - discovery.type=single-node
+    ports:
+      - "9200:9200"
+```
+
+```python
+# 需要数据同步脚本
+from elasticsearch import Elasticsearch
+
+def sync_data_to_es():
+    # 从数据湖读取数据
+    # 转换格式
+    # 同步到Elasticsearch
+    pass
+```
+
+## 附录# Lakehouse原生全文检索
+
+```sql
+-- 一站式解决方案
+CREATE TABLE documents (
+    id BIGINT,
+    content STRING,
+    INDEX content_idx (content) INVERTED PROPERTIES('analyzer'='chinese')
+);
+
+-- 直接使用内置函数
+SELECT * FROM documents 
+WHERE MATCH_ALL(content, '人工智能 机器学习', map('analyzer', 'auto'));
+```
+
+## 附录# 方案对比总结

+## 附录 倒排索引核心概念
+
+## 附录# 倒排索引原理
+
+**基本概念**：
+
+* **词典（Dictionary）**：存储所有文档中出现的唯一单词列表
+* **倒排表（Posting List）**：记录每个单词在哪些文档中出现及位置信息
+
+**构建过程**：
+
+1. **分词（Tokenization）**：将文档内容分割成单词或短语
+2. **标准化（Normalization）**：转小写、去除停用词等处理
+3. **构建词典**：为每个单词分配唯一ID
+4. **构建倒排表**：记录单词与文档的映射关系
+
+## 附录# 索引创建语法
+
+## 附录## 附录 建表时定义索引
+
+```sql
+CREATE TABLE table_name (
+    column_definitions,
+    INDEX index_name (column_name) INVERTED 
+    [COMMENT 'description'] 
+    PROPERTIES(
+        'analyzer'='english|chinese|keyword|unicode',

+## 附录 索引管理
+
+## 附录# 索引生命周期
+
+## 附录## 附录 1. 创建索引
+
+```sql
+-- 方式1：建表时创建
+CREATE TABLE documents (
+    id BIGINT,
+    content STRING,
+    INDEX content_idx (content) INVERTED PROPERTIES('analyzer'='chinese')
+);
+
+-- 方式2：为已有表创建
+CREATE INVERTED INDEX content_idx ON TABLE documents(content) 
+PROPERTIES('analyzer'='chinese', 'mode'='smart');
+```
+
+## 附录## 附录 2. 构建索引（重要！）
+
+```sql
+-- 对已有数据构建索引（同步任务）
+BUILD INDEX content_idx ON documents;
+
+-- 按分区构建索引
+BUILD INDEX content_idx ON documents 
+WHERE partition_date >= '2024-01-01';
+```
+
+⚠️ **关键提醒**：
+
+* `CREATE INDEX` 仅对新增数据生效
+* 已有数据必须执行 `BUILD INDEX` 才能利用索引
+* 构建索引会消耗计算资源，建议在业务低峰期执行
+
+## 附录## 附录 3. 查看索引
+
+```sql
+-- 列出表上所有索引
+SHOW INDEX FROM table_name;
+
+-- 查看索引详情（如果环境支持）
+DESC INDEX index_name;
+DESC INDEX EXTENDED index_name;  -- 包含大小信息
+```
+
+## 附录## 附录 4. 删除索引
+
+```sql
+DROP INDEX index_name ON table_name;
+```
+
+**删除特点**：
+
+* 立即删除元数据
+* 索引文件异步清理
+* 不影响数据本身

+
+-- ✅ 方案2：手动匹配索引分词器
+SELECT * FROM docs 
+WHERE MATCH_ANY(content, '测试', map('analyzer', 'chinese'));
+```
+
+## 附录# 索引构建避坑
+
+## 附录## 附录 BUILD INDEX的必要性
+
+```sql
+-- ❌ 常见错误：忘记构建索引
+CREATE INVERTED INDEX content_idx ON TABLE existing_table(content) 
+PROPERTIES('analyzer'='chinese');
+
+-- 直接查询（只对新数据有效，已有数据无法利用索引）
+SELECT * FROM existing_table 
+WHERE MATCH_ANY(content, '关键词', map('analyzer', 'auto'));
+```
+
+## 附录## 附录 正确的索引构建流程
+
+```sql
+-- ✅ 完整流程
+-- 1. 创建索引
+CREATE INVERTED INDEX content_idx ON TABLE existing_table(content) 
+PROPERTIES('analyzer'='chinese');
+
+-- 2. 构建索引（必须！）
+BUILD INDEX content_idx ON existing_table;
+
+-- 3. 验证索引
+SHOW INDEX FROM existing_table;
+
+-- 4. 执行查询
+SELECT * FROM existing_table 
+WHERE MATCH_ANY(content, '关键词', map('analyzer', 'auto'));
+```

+
+<1秒）
+-- 3. 简单的等值查询
+
+-- ✅ 适合倒排索引的场景
+-- 1. 大数据量表（万行以上）
+-- 2. 复杂的文本搜索
+-- 3. 多关键词匹配
+```
+
+#### 不支持的查询模式
+
+```sql
+-- ❌ 不支持：对列进行类型转换
+SELECT * FROM docs 
+WHERE MATCH_ANY(CAST(id AS STRING), '123', map('analyzer', 'auto'));
+
+-- ✅ 支持：对查询值进行转换
+SELECT * FROM docs 
+WHERE MATCH_ANY(content, CAST(123 AS STRING), map('analyzer', 'auto'));
+
+-- ❌ 不支持：外部表
+-- 倒排索引不支持外部表
+```
+
+### 存储成本避坑
+
+#### 索引存储开销
+
+```sql
+-- 倒排索引会创建额外的索引文件
+-- 存储成本 = 原始数据 + 索引文件
+
+-- 优化建议：
+-- 1. 仅为真正需要搜索的列创建索引
+-- 2. 根据查询模式选择合适的分词器
+-- 3. 定期清理不必要的索引
+```
+
+#### 分词器选择策略
+
+| 分词器     | 索引大小 | 查询性能 | 功能丰富度 | 推荐场景     |
+| ------- | ---- | ---- | ----- | -------- |
+| keyword | 最小   | 最快   | 精确匹配  | ID、状态、标签 |
+| english | 小    | 快    | 英文分词  | 纯英文内容    |
+| chinese | 中等   | 中等   | 中文分词  | 中文文档     |
+| unicode | 最大   | 相对慢  | 全语言支持 | 多语言混合    |
+
+***
+
+## 性能优化
+
+### 查询优化策略
+
+#### 1. 合理选择查询函数
+
+```sql
+-- 根据业务需求选择合适的函数
+-- 精确搜索：使用 MATCH_ALL
+SELECT * FROM docs WHERE MATCH_ALL(content, '机器学习 算法', map('analyzer', 'auto'));
+
+-- 宽泛搜索：使用 MATCH_ANY  
+SELECT * FROM docs WHERE MATCH_ANY(content, '人工智能 机器学习 深度学习', map('analyzer', 'auto'));
+
+-- 短语搜索：使用 MATCH_PHRASE
+SELECT * FROM docs WHERE MATCH_PHRASE(content, '自然语言处理', map('analyzer', 'auto'));
+```
+
+#### 2. 组合查询优化
+
+```sql
+-- ✅ 推荐：将全文检索作为主要过滤条件
+SELECT * FROM documents 
+WHERE MATCH_ANY(content, '关键词', map('analyzer', 'auto'))
+  AND category = 'tech'  -- 在全文检索基础上进行二次过滤
+  AND created_at >
+
+## 附录## 附录 3. 分页查询优化
+
+```sql
+-- ✅ 高效的分页查询
+SELECT id, title FROM documents 
+WHERE MATCH_ANY(content, '关键词', map('analyzer', 'auto'))
+ORDER BY id  -- 使用主键排序
+LIMIT 20 OFFSET 0;
+
+-- ⚠️ 避免深度分页
+-- LIMIT 20 OFFSET 10000; -- 性能会随offset增大而下降
+```

+## 生成列
+生成列（Generated Columns）是数据库表中的一列，其值由表中的其他列的值通过一个表达式自动计算生成。这种列在创建时就定义了一个计算规则，数据库管理系统会根据这个规则自动填充列的值，而不需要用户显式地插入或更新这些值。应用场景比如数据集成同步时不支持转化，可以使用生成列进行转化。
+
+## 语法
+
+```SQL
+CREATE TABLE [ IF NOT EXISTS ] table_name
+(
+    column_definition GENERATED ALWAYS AS ( expr ), [column_definition,...]
+)
+[ PARTITIONED BY (column_name column_type | column_name ) ];
+```
+
+
+* **GENERATED ALWAYS AS (expr)**：通过表达式`expr`自动生成列的值。表达式可以包含常量和内置标量确定性SQL函数，不支持非确定性函数如（current\_date\random\current\_timestamp\上下文函数）或运算符，不支持聚合函数、窗口函数或表函数。支持分区列使用生成列
+
+**示例**：
+
+```SQL
+-- 正确使用
+CREATE TABLE t_genet (
+    col1 TIMESTAMP,
+    hour int GENERATED ALWAYS AS (hour(col1)),
+    pt STRING GENERATED ALWAYS AS (date_format(col1, 'yyyy-MM-dd'))
+) PARTITIONED BY (pt);
+```
+### 生成列和默认值区别
+
+1. **分区列支持**：
+
+   1. **默认值**：当前不支持为分区列设置默认值。
+   2. **生成列**：支持为分区列生成值。
+
+2. **函数支持**：
+
+   1. **默认值**：支持使用非确定性函数，如 `current_timestamp()`
+   2. **生成列**：不支持非确定性函数，只能使用确定性的标量函数。
+
+3. **插入操作中的值指定**：
+
+   1. **默认值**：在插入数据时，可以为列指定一个静态值，如果未指定，则使用默认值。
+   2. **生成列**：在插入数据时，不能为生成列指定值，其值完全由生成表达式决定。
+
+4. **列值来源**：
+
+   1. **默认值**：不支持列的值来自其他列的转换。
+   2. **生成列**：支持列的值来自其他列的转换，即可以基于其他列的值计算生成。
+
+5. **现有数据行的处理**：
+
+   1. **默认值**：当为现有表添加带有默认值的列时，已存在的数据行中的该列将填充为null。
+   2. **生成列**：对于已存在的数据行，生成列的值将根据生成表达式进行转换，并显示转换后的数据。
+
+### 使用限制
+
+* 使用生成列时，您不能在插入操作中显式指定该列的值，它将由表达式自动生成。但是为了兼容Hive语法，Lakehouse允许您为分区字段指定一个静态值。然而，指定的静态值不会生效，查询结果仍然是由指定生成列表达式结果决定
+* 不支持使用实时接口和批量接口写入，包括Studio数据集成的批量导入和实时写入。
+* 生成列不支持非确定性函数如（current\_date\random\current\_timestamp\上下文函数）或运算符，不支持聚合函数、窗口函数或表函数。
+
+### 插入数据
+
+* 当使用生成列时，您不能为该列指定常量值。例如，如果hour列是由`col1`生成的，您不能在插入时指定hour的值。指定则会报错。
+
+**错误示例**：
+
+```SQL
+-- 指定的2024-09-26将不会生效，因为pt是由col1生成的，虽然不会报错，但是值不会写入当中
+CREATE TABLE t_genet (
+    col1 TIMESTAMP,
+    pt STRING GENERATED ALWAYS AS (date_format(col1, 'yyyy-MM-dd'))
+) PARTITIONED BY (pt);
+INSERT INTO t_genet (col1,pt) VALUES (current_timestamp, '2024-09-26');
+```
+
+**正确示例**：
+
+```SQL
+-- 可以运行，只插入col1，pt将由生成规则自动计算
+INSERT INTO t_genet (col1) VALUES (current_timestamp);
+```
+
+# 添加字段时指定生成列
+
+## 语法
+
+```SQL
+-- 添加列
+ALTER TABLE table_name ADD COLUMN
+      column1_name_identifier data_type [column_properties]
+      [FIRST | AFTER column1_name_identifier]  ,....
+
+column_properties:==
+    GENERATED ALWAYS AS ( expr ) |
+    COMMENT column_comment 
+```
+
+* **GENERATED ALWAYS AS (expr)**：指定一个表达式，用于自动生成新添加列的值。对于表中已存在的数据行，该列将根据表达式的结果填充值。表达式可以包含常量和内置标量确定性SQL函数，非确定性函数如（current\_date\random\current\_timestamp等）或运算符，不支持聚合函数、窗口函数或表函数。
+
+
+## 使用限制
+
+* 不支持在已有的列添加生成列
+
+## 示例
+
+### 添加生成列
+
+```SQL
+ALTER TABLE my_table ADD COLUMN
+    generated_col TIMESTAMP GENERATED ALWAYS AS (date_format(col1, 'yyyy-MM-dd')) FIRST;
+```
+
+在这个例子中，`generated_col` 将被添加为表中的第一列，并且所有现有的数据行的 `generated_col` 将根据当前时间戳生成值。

+
+### 适用场景
+
+* 时间维度分析（按日期、小时等分组查询）
+* 数据分类和标准化（状态判断、等级划分）
+* 需要统一业务规则的场景
+* 基于计算结果进行分区的需求
+
+***
+
+## 基础语法
+
+### 创建语法
+
+```sql
+-- 完整的CREATE TABLE语法
+CREATE TABLE table_name (
+    column_definition,
+    column_name data_type GENERATED ALWAYS AS ( expression ) [COMMENT comment],
+    [column_definition,...]
+) [ PARTITIONED BY (column_name) ];
+
+-- ALTER TABLE添加生成列语法
+ALTER TABLE table_name ADD COLUMN 
+column_name data_type GENERATED ALWAYS AS ( expression ) 
+[COMMENT comment];
+```
+
+### 5分钟上手示例
+
+```sql
+-- 创建表时定义生成列
+CREATE TABLE orders (
+    order_id INT,
+    order_time TIMESTAMP_LTZ,
+    amount DOUBLE,
+    order_date STRING GENERATED ALWAYS AS (date_format(order_time, 'yyyy-MM-dd')),
+    order_hour INT GENERATED ALWAYS AS (hour(order_time)),
+    amount_level STRING GENERATED ALWAYS AS (
+        if(amount >= 1000, 'HIGH',
+           if(amount >= 500, 'MEDIUM', 'LOW'))
+    )
+);
+
+-- 插入数据：只需提供基础列
+INSERT INTO orders (order_id, order_time, amount) VALUES 
+(1001, TIMESTAMP '2024-06-19 14:30:00', 299.99);
+
+-- 查询结果：自动包含生成列
+SELECT * FROM orders;
+-- 结果：order_date='2024-06-19', order_hour=14, amount_level='LOW'
+
+-- 后续添加生成列
+ALTER TABLE orders ADD COLUMN 
+year_col INT GENERATED ALWAYS AS (year(order_time)) COMMENT '年份列';
+```
+
+***
+
+## 验证清单
+
+### 创建后验证（每次必做）
+
+```sql
+-- 1. 创建带生成列的表
+CREATE TABLE orders_test (
+    order_id INT,
+    order_time TIMESTAMP_LTZ,
+    amount DOUBLE,
+    hour_col INT GENERATED ALWAYS AS (hour(order_time)),
+    date_str STRING GENERATED ALWAYS AS (date_format(order_time, 'yyyy-MM-dd'))
+);
+
+-- 2. 验证表结构
+DESCRIBE TABLE orders_test;
+-- ✅ 检查：生成列是否出现在表结构中
+
+-- 3. 测试数据插入
+INSERT INTO orders_test (order_id, order_time, amount) VALUES 
+(1001, TIMESTAMP '2024-06-19 14:30:00', 299.99);
+
+-- 4. 验证生成列值
+SELECT order_id, order_time, hour_col, date_str FROM orders_test;
+-- ✅ 检查：hour_col=14, date_str='2024-06-19'
+
+-- 5. 验证插入保护机制
+-- INSERT INTO orders_test (order_id, order_time, hour_col) VALUES 
+-- (1002, TIMESTAMP '2024-06-19 15:30:00', 999);
+-- ✅ 检查：应该报错"cannot insert or update generated column"
+
+-- 6. 验证ALTER TABLE添加生成列
+ALTER TABLE orders_test ADD COLUMN 
+year_col INT GENERATED ALWAYS AS (year(order_time));
+
+-- 7. 验证存量数据回填
+SELECT order_id, order_time, year_col FROM orders_test;
+-- ✅ 检查：year_col=2024（存量数据自动计算）
+```

+-- 1. MySQL: AS (expression) [STORED|VIRTUAL]
+-- 2. Lakehouse: GENERATED ALWAYS AS (expression)
+-- 3. Lakehouse只支持STORED模式（物理存储）
+```
+
+### PostgreSQL迁移
+
+```sql
+-- PostgreSQL语法
+-- CREATE TABLE postgres_table (
+--     id INT,
+--     first_name TEXT,
+--     last_name TEXT,
+--     full_name TEXT GENERATED ALWAYS AS (first_name || ' ' || last_name) STORED
+-- );
+
+-- 云器Lakehouse等价语法
+CREATE TABLE lakehouse_table (
+    id INT,
+    first_name STRING,
+    last_name STRING,
+    full_name STRING GENERATED ALWAYS AS (concat(first_name, ' ', last_name))
+);
+
+-- 主要差异：
+-- 1. 字符串连接：PostgreSQL用||，Lakehouse用concat()函数
+```
+
+### Oracle迁移
+
+```sql
+-- Oracle虚拟列语法
+-- CREATE TABLE oracle_table (
+--     id NUMBER,
+--     birth_date DATE,
+--     age NUMBER GENERATED ALWAYS AS (
+--         FLOOR(MONTHS_BETWEEN(SYSDATE, birth_date) / 12)
+--     ) VIRTUAL
+-- );
+
+-- 云器Lakehouse调整后语法
+CREATE TABLE lakehouse_table (
+    id INT,
+    birth_date DATE,
+    -- Oracle的SYSDATE是非确定性的，需要重新设计
+    year_part INT GENERATED ALWAYS AS (year(birth_date))
+);
+
+-- 主要差异：
+-- 1. Oracle支持非确定性函数，Lakehouse不支持
+-- 2. Oracle的CASE WHEN支持，Lakehouse需要用if()嵌套
+```
+
+### Hive/Spark迁移
+
+```sql
+-- Hive/Spark通常使用视图
+-- CREATE VIEW hive_view AS
+-- SELECT id, event_time, 
+--        hour(event_time) as hour_col,
+--        date_format(event_time, 'yyyy-MM-dd') as date_str
+-- FROM raw_table;
+
+-- 云器Lakehouse生成列：真实物理存储，性能更好
+CREATE TABLE lakehouse_table (
+    id INT,
+    event_time TIMESTAMP_LTZ,
+    hour_col INT GENERATED ALWAYS AS (hour(event_time)),
+    date_str STRING GENERATED ALWAYS AS (date_format(event_time, 'yyyy-MM-dd'))
+);
+
+-- 优势对比：
+-- Hive/Spark视图：查询时计算，性能开销大
+-- Lakehouse生成列：预计算存储，查询性能好
+```
+
+***
+
+## 高级使用场景
+
+### 生成列 + 分区组合
+
+```sql
+-- 时间分区自动化
+CREATE TABLE sales_auto_partition (
+    sale_id INT,
+    customer_id INT,
+    sale_time TIMESTAMP_LTZ,
+    amount DOUBLE,
+    sale_date STRING GENERATED ALWAYS AS (date_format(sale_time, 'yyyy-MM-dd'))
+) PARTITIONED BY (sale_date);
+
+-- 插入数据：无需计算分区值
+INSERT INTO sales_auto_partition (sale_id, customer_id, sale_time, amount) VALUES 
+(1001, 5001, TIMESTAMP '2024-06-19 14:30:00', 299.99),
+(1002, 5002, TIMESTAMP '2024-06-20 09:15:00', 599.00);
+
+-- 查询优势：自动分区裁剪
+SELECT * FROM sales_auto_partition 
+WHERE sale_time >= '2024-06-19'  -- 自动转换为分区条件
+  AND customer_id = 5001;
+```
+
+### 复杂业务逻辑封装
+
+```sql
+-- 业务逻辑封装在生成列中
+CREATE TABLE order_analysis (
+    order_id INT,
+    customer_id INT,
+    order_time TIMESTAMP_LTZ,
+    amount DOUBLE,
+    
+    -- 时间维度生成列
+    order_date STRING GENERATED ALWAYS AS (date_format(order_time, 'yyyy-MM-dd')),
+    order_hour INT GENERATED ALWAYS AS (hour(order_time)),
+    order_quarter STRING GENERATED ALWAYS AS (
+        concat(cast(year(order_time) as string), '-Q', cast(quarter(order_time) as string))
+    ),
+    
+    -- 业务逻辑生成列（使用if()嵌套）
+    amount_level STRING GENERATED ALWAYS AS (
+        if(amount >= 1000, 'HIGH',
+           if(amount >= 500, 'MEDIUM', 'LOW'))
+    ),
+    
+    -- 时间段分类
+    time_period STRING GENERATED ALWAYS AS (
+        if(hour(order_time) >= 6 AND hour(order_time) <= 11, 'MORNING',
+           if(hour(order_time) >= 12 AND hour(order_time) <= 17, 'AFTERNOON',
+              if(hour(order_time) >= 18 AND hour(order_time) <= 23, 'EVENING', 'NIGHT')))
+    )
+) PARTITIONED BY (order_date);
+```
+
+### 数据质量保证
+
+```sql
+-- 数据标准化和清洗
+CREATE TABLE customer_data_clean (
+    customer_id INT,
+    raw_phone STRING,
+    raw_email STRING,
+    registration_time TIMESTAMP_LTZ,
+    
+    -- 数据清洗生成列
+    clean_phone STRING GENERATED ALWAYS AS (
+        regexp_replace(raw_phone, '[^0-9]', '')  -- 只保留数字
+    ),
+    clean_email STRING GENERATED ALWAYS AS (
+        lower(trim(raw_email))  -- 转小写并去空格
+    ),

+        if(raw_email LIKE '%@%' AND raw_email LIKE '%.%', 'VALID', 'INVALID')
+    ),
+    
+    -- 注册时间维度
+    reg_date STRING GENERATED ALWAYS AS (date_format(registration_time, 'yyyy-MM-dd'))
+) PARTITIONED BY (reg_date);
+```

+        )
+    )
+) PARTITIONED BY (date_str);
+```
+

+
+## 使用限制和避坑指南
+
+### 关键限制
+
+#### 1. 条件表达式限制
+
+```sql
+-- ❌ 错误：使用CASE WHEN表达式（不支持）
+CREATE TABLE wrong_table (
+    score INT,
+    grade STRING GENERATED ALWAYS AS (
+        CASE 
+            WHEN score >= 90 THEN 'A'
+            WHEN score >= 80 THEN 'B'
+            ELSE 'C'
+        END
+    )
+);
+
+-- ✅ 正确做法：使用if()函数嵌套
+CREATE TABLE correct_table (
+    score INT,
+    grade STRING GENERATED ALWAYS AS (
+        if(score >= 90, 'A',
+           if(score >= 80, 'B', 'C'))
+    )
+);
+```
+
+#### 2. 函数支持限制
+
+```sql
+-- ❌ 常见错误：使用不支持的函数
+CREATE TABLE wrong_functions (
+    id INT,
+    created_at TIMESTAMP_LTZ GENERATED ALWAYS AS (current_timestamp()),  -- 非确定性
+    random_val DOUBLE GENERATED ALWAYS AS (random()),                    -- 非确定性
+    name_cap STRING GENERATED ALWAYS AS (initcap('test'))               -- 函数不存在
+);
+
+-- ✅ 正确做法：使用支持的确定性函数
+CREATE TABLE correct_functions (
+    id INT,
+    input_time TIMESTAMP_LTZ,
+    hour_part INT GENERATED ALWAYS AS (hour(input_time)),
+    formatted STRING GENERATED ALWAYS AS (date_format(input_time, 'yyyy-MM-dd'))
+);
+```
+
+#### 3. ALTER TABLE限制
+
+```sql
+-- ❌ 错误：不能在已有列上添加生成列属性
+-- ALTER TABLE existing_table MODIFY COLUMN existing_col GENERATED ALWAYS AS (expression);
+
+-- ✅ 正确做法：只能添加新的生成列
+ALTER TABLE existing_table ADD COLUMN 
+new_generated_col INT GENERATED ALWAYS AS (expression);
+```
+
+### 最佳实践
+
+1. **表达式设计原则**
+   * 使用if()嵌套替代CASE WHEN
+   * 使用简单确定性函数
+   * 确保表达式性能良好
+   * 注意返回类型与列类型匹配
+
+2. **命名规范建议**
+   ```sql
+   CREATE TABLE naming_example (
+       raw_timestamp TIMESTAMP_LTZ,           -- 基础列：原始数据
+       gen_hour INT GENERATED ALWAYS AS (hour(raw_timestamp)),              -- 生成列：gen_前缀
+       gen_date STRING GENERATED ALWAYS AS (date_format(raw_timestamp, 'yyyy-MM-dd'))
+   );
+   ```
+
+3. **函数使用建议**
+   * 验证函数支持：新函数使用前先创建测试表验证
+   * 使用try\_cast进行安全转换
+   * 注意函数语法差异
+
+***
+
+## 实战迁移案例
+
+### 案例1：电商订单表迁移（MySQL → 云器Lakehouse）
+
+#### 原始MySQL表结构
+
+```sql
+-- 原MySQL表：手动计算衍生字段
+CREATE TABLE orders_mysql (
+    order_id INT PRIMARY KEY,
+    customer_id INT,
+    order_time TIMESTAMP,
+    amount DECIMAL(10,2),
+    order_date DATE,           -- 手动计算
+    order_hour INT,           -- 手动计算
+    amount_level VARCHAR(10)  -- 手动计算
+);
+```
+
+#### 云器Lakehouse生成列方案
+
+```sql
+-- 迁移后的设计
+CREATE TABLE orders_lakehouse (
+    order_id INT,
+    customer_id INT,
+    order_time TIMESTAMP_LTZ,
+    amount DOUBLE,
+    -- 生成列：自动计算，确保一致性
+    order_date STRING GENERATED ALWAYS AS (date_format(order_time, 'yyyy-MM-dd')),
+    order_hour INT GENERATED ALWAYS AS (hour(order_time)),
+    amount_level STRING GENERATED ALWAYS AS (
+        if(amount >= 1000, 'HIGH',
+           if(amount >= 500, 'MEDIUM', 'LOW'))
+    )
+) PARTITIONED BY (order_date);
+
+-- 应用程序只需插入基础字段
+INSERT INTO orders_lakehouse (order_id, customer_id, order_time, amount) VALUES 
+(1001, 5001, TIMESTAMP '2024-06-19 14:30:00', 299.99);
+```
+
+#### 迁移效果对比
+
+* **查询速度**：提升60%（避免重复计算）
+* **开发效率**：提升80%（无需手动计算逻辑）
+* **数据一致性**：提升100%（统一计算逻辑）
+
+***
+
+## 性能优化建议
+
+### 索引策略
+
+* 为经常用于WHERE条件和GROUP BY的生成列创建索引
+* 时间维度的生成列通常需要索引
+* 监控生成列的基数，基数过低的生成列不适合创建索引
+
+### 表达式优化
+
+* 表达式设计要简洁高效
+* 避免过于复杂的嵌套if()语句
+* 复杂逻辑可以拆分为多个简单的生成列
+* 建议每张表的生成列数量控制在5-10个以内
+
+### 查询优化
+
+* 使用生成列而不是重新计算原表达式
+* 确保分区值分布均匀，避免数据倾斜
+* 定期检查生成列的查询性能表现
+
+***
+
+## 故障排查手册
+
+### 基础功能验证
+
+```sql
+-- 1. 表结构验证
+DESCRIBE TABLE your_table_name;
+-- 检查：生成列是否出现在列表中，数据类型是否正确
+
+-- 2. 基本插入测试
+INSERT INTO your_table_name (base_column1, base_column2) VALUES (test_value1, test_value2);
+-- 检查：是否能成功插入数据
+
+-- 3. 生成列值验证
+SELECT base_column1, base_column2, generated_column1, generated_column2 FROM your_table_name;
+-- 检查：生成列的值是否符合预期表达式结果
+
+-- 4. 插入保护机制验证
+-- INSERT INTO your_table_name (base_column1, generated_column1) VALUES (value1, invalid_value);
+-- 检查：是否正确报错"cannot insert or update generated column"
+```
+
+### 高级功能验证
+
+```sql
+-- 5. 分区生成列验证（如果使用）
+SHOW PARTITIONS your_partitioned_table;
+-- 检查：分区是否按生成列的值正确创建
+
+-- 6. 复杂表达式验证
+SELECT generated_column, 
+       manual_calculation_expression,  -- 手动计算作为对比
+       if(generated_column = manual_calculation_expression, 'MATCH', 'MISMATCH') as validation
+FROM your_table_name;
+-- 检查：生成列值与手动计算是否一致
+```
+
+### 常见问题排查
+
+#### 问题1：CASE WHEN表达式不支持
+
+**解决方案**：改用if()嵌套
+
+```sql
+-- 原CASE WHEN逻辑：
+-- CASE WHEN score >= 90 THEN 'A' WHEN score >= 80 THEN 'B' ELSE 'C' END
+
+-- 改为if()嵌套：
+if(score >= 90, 'A', if(score >= 80, 'B', 'C'))
+```
+
+#### 问题2：函数不支持
+
+**解决方案**：使用支持的函数替代
+
+```sql
+-- log(x) -> log10(x)
+-- initcap(str) -> 使用upper/lower组合
+-- CASE WHEN -> if()嵌套
+```

+# Lakehouse 地理信息函数部署与使用指南
+
+## 概述
+
+本文档详细介绍如何在 ClickZetta Lakehouse 中部署和使用 Esri 地理信息函数，实现空间数据的存储、查询和分析。通过本指南，您将学会：
+
+* 部署地理信息函数所需的 JAR 包
+* 创建外部函数连接
+* 批量创建常用的地理信息函数
+* 在实际场景中使用这些函数，例如：
+  * 地理围栏分析：判断门店是否在其对应的服务区域内 ![](.topwrite/assets/geo4.jpeg =774)
+  * 区域统计分析：统计各服务区域内的门店分布情况 ![](.topwrite/assets/geo5.jpeg =757)
+
+> **Esri Geometry**：**esri-geometry-api** 和 **spatial-sdk-hive** 是 Esri 公司开源的地理计算库，在大数据领域应用极其广泛。
+>
+> **核心优势**：
+>
+> * **行业标准**：Esri 作为 GIS 领导者，其几何算法库已成为事实标准
+> * **功能完整**：支持 OGC 全部标准，包括点、线、面等几何类型及空间运算
+> * **应用场景**：物流配送、LBS 服务、商圈分析、城市规划
+>
+> 通过集成 Esri 公司开源的地理计算库，Lakehouse 提供了标准化的地理数据处理能力
+
+## 前置条件
+
+* Lakehouse 环境已就绪
+* 具有创建外部函数和 API CONNECTION 的权限
+
+## 第一步：准备 JAR 包
+
+### 1.1 下载所需 JAR 包
+
+从 Esri 官方仓库下载以下两个 JAR 包：
+
+```
+# ESRI Geometry API
+wget https://github.com/Esri/geometry-api-java/releases/download/v2.2.0/esri-geometry-api-2.2.0.jar
+
+# Spatial Framework for Hadoop
+wget https://github.com/Esri/spatial-framework-for-hadoop/releases/download/v2.2.0/spatial-sdk-hive-2.2.0.jar
+```
+
+### 1.2 上传 JAR 包到 USER VOLUME
+
+将下载的 JAR 包上传到 Lakehouse 的 USER VOLUME（上传操作仅支持在 Lakehouse 客户端（如 [SQLLine](connect-with-cli.md)）中执行，不支持在 Lakehouse Studio 中执行）：
+
+```
+PUT '/Users/derekmeng/Downloads/esri-geometry-api-2.2.0.jar' to USER VOLUME;
+PUT '/Users/derekmeng/Downloads/spatial-sdk-hive-2.2.0.jar' to USER VOLUME;
+```
+
+## 第二步：创建 API Connection
+
+如果还没有合适的 API Connection，需要先创建一个。本例使用阿里云函数计算，详细步骤请参考：[创建 API CONNECTION](create-api-connection.md)
+
+```
+CREATE API CONNECTION fc_api_conn
+TYPE cloud_function
+  provider = 'aliyun'
+  region = 'cn-shanghai'
+  role_arn = 'acs:ram::122280886xxxxxxx:role/functionrole'
+  namespace = 'default'
+  code_bucket = '[bucket_name]';
+```
+

+## 第三步：批量创建地理信息函数
+
+### 3.1 创建常用的地理信息函数
+
+以下是生产环境中最常用的地理信息函数创建脚本，详细信息请参考创建外部函数（[CREATE EXTERNAL FUNCTION](CREATE_EXTERNATL_FUNCTION.md)）：
+
+```
+-- ========================================
+-- 1. 几何体构造函数
+-- ========================================
+
+-- 创建点
+CREATE EXTERNAL FUNCTION public.ST_Point AS 'com.esri.hadoop.hive.ST_Point' 
+USING jar 'volume:user://~/esri-geometry-api-2.2.0.jar', 
+      jar 'volume:user://~/spatial-sdk-hive-2.2.0.jar' 
+CONNECTION sg_fc_api_conn 
+WITH PROPERTIES ( 
+    'remote.udf.api' = 'java8.hive2.v0', 
+    'remote.udf.protocol' = 'http.arrow.v0' 
+);
+

+
+-- ========================================

+
+-- ========================================
+-- 5. 几何属性提取函数
+-- ========================================
+
+-- 提取点的 X 坐标（经度）

+);
+
+-- 查看已创建的地理信息函数
+USE public;
+SHOW EXTERNAL FUNCTIONS;
+
+
+```
+
+## 第四步：创建测试数据
+
+为了验证函数功能，创建包含地理信息的测试表：
+
+```
+-- 创建门店位置表
+CREATE TABLE IF NOT EXISTS store_locations (
+    store_id INT,
+    store_name STRING,
+    location STRING,  -- WKT 格式的点
+    city STRING,
+    store_type STRING
+);
+
+-- 创建服务区域表
+CREATE TABLE IF NOT EXISTS service_areas (
+    area_id INT,
+    area_name STRING,
+    boundary STRING,  -- WKT 格式的多边形
+    area_type STRING,
+    city STRING
+);
+
+-- 插入示例门店数据
+INSERT INTO store_locations VALUES 
+(1, '北京王府井店', 'POINT(116.410 39.914)', '北京', '旗舰店'),
+(2, '北京三里屯店', 'POINT(116.454 39.934)', '北京', '标准店'),
+(3, '上海南京路店', 'POINT(121.473 31.232)', '上海', '旗舰店'),
+(4, '上海徐家汇店', 'POINT(121.437 31.195)', '上海', '标准店'),
+(5, '深圳华强北店', 'POINT(114.085 22.547)', '深圳', '标准店'),
+(6, '深圳福田CBD店', 'POINT(114.059 22.536)', '深圳', '旗舰店'),
+(7, '广州天河店', 'POINT(113.321 23.125)', '广州', '旗舰店'),
+(8, '杭州西湖店', 'POINT(120.147 30.242)', '杭州', '标准店');
+
+-- 插入示例服务区域数据
+INSERT INTO service_areas VALUES 
+(1, '北京核心商圈', 'POLYGON((116.38 39.88, 116.48 39.88, 116.48 39.96, 116.38 39.96, 116.38 39.88))', '核心区', '北京'),
+(2, '上海市中心', 'POLYGON((121.43 31.18, 121.52 31.18, 121.52 31.26, 121.43 31.26, 121.43 31.18))', '核心区', '上海'),
+(3, '深圳福田区', 'POLYGON((114.02 22.51, 114.13 22.51, 114.13 22.58, 114.02 22.58, 114.02 22.51))', '商业区', '深圳'),
+(4, '配送范围A', 'POLYGON((116.35 39.85, 116.50 39.85, 116.50 39.98, 116.35 39.98, 116.35 39.85))', '配送区', '北京'),
+(5, '配送范围B', 'POLYGON((121.40 31.15, 121.55 31.15, 121.55 31.28, 121.40 31.28, 121.40 31.15))', '配送区', '上海');
+```
+
+## 第五步：生产场景验证
+
+### 场景 1：地理围栏分析——判断门店是否在服务区域内
+
+这是最常见的应用场景，用于判断用户、门店或设备是否在指定的服务范围内。
+
+```
+-- 查询哪些门店在各个服务区域内
+SELECT 
+    s.store_name,
+    s.city as store_city,
+    a.area_name,
+    a.area_type
+FROM 
+    store_locations s
+    JOIN service_areas a
+    ON public.ST_Contains(
+        public.ST_GeomFromText(a.boundary), 
+        public.ST_GeomFromText(s.location)
+    ) = true
+ORDER BY a.area_name, s.store_name;
+
+-- 统计每个服务区域内的门店数量
+SELECT 
+    a.area_name,
+    a.area_type,
+    COUNT(s.store_id) as store_count,
+    COLLECT_LIST(s.store_name) as stores_in_area
+FROM 
+    service_areas a
+    LEFT JOIN store_locations s
+    ON public.ST_Contains(
+        public.ST_GeomFromText(a.boundary), 
+        public.ST_GeomFromText(s.location)
+    ) = true
+GROUP BY a.area_name, a.area_type
+ORDER BY store_count DESC;
+```
+
+### 场景 2：最近邻查询——查找最近的门店
+
+用于为用户推荐最近的服务点，或进行资源分配。
+
+```
+-- 查找距离指定位置最近的3家门店
+WITH user_location AS (
+    SELECT public.ST_Point(116.397, 39.908) as location  -- 北京天安门位置
+)
+SELECT 
+    s.store_name,
+    s.city,
+    s.store_type,
+    public.ST_Distance(
+        u.location,
+        public.ST_GeomFromText(s.location)
+    ) as distance_degrees,
+    -- 粗略转换为公里（1度约等于111公里）
+    public.ST_Distance(
+        u.location,
+        public.ST_GeomFromText(s.location)
+    ) * 111 as distance_km
+FROM 
+    store_locations s
+    CROSS JOIN user_location u
+ORDER BY distance_degrees
+LIMIT 3;
+```
+
+### 场景 3：缓冲区分析——创建配送范围
+
+为每个门店创建配送范围，用于服务范围规划。
+
+```
+-- 为旗舰店创建5公里配送范围（约0.045度）
+SELECT 
+    store_name,
+    city,
+    location as original_location,
+    public.ST_Buffer(
+        public.ST_GeomFromText(location),
+        0.045  -- 约5公里
+    ) as delivery_area
+FROM 
+    store_locations
+WHERE 
+    store_type = '旗舰店';
+
+-- 查询某个点是否在任意旗舰店的配送范围内
+WITH delivery_zones AS (
+    SELECT 
+        store_name,
+        public.ST_Buffer(
+            public.ST_GeomFromText(location),
+            0.045
+        ) as delivery_area
+    FROM 
+        store_locations
+    WHERE 
+        store_type = '旗舰店'
+),
+test_point AS (
+    SELECT public.ST_Point(116.420, 39.920) as location  -- 测试点
+)
+SELECT 
+    d.store_name,
+    CASE 
+        WHEN public.ST_Contains(d.delivery_area, t.location) = true 
+        THEN '在配送范围内'
+        ELSE '不在配送范围内'
+    END as delivery_status
+FROM 
+    delivery_zones d
+    CROSS JOIN test_point t;
+```
+
+### 场景 4：区域统计分析
+
+统计各个区域的业务指标，用于商业分析。
+
+```
+-- 创建销售数据表
+CREATE TABLE IF NOT EXISTS store_sales (
+    store_id INT,
+    sales_amount DECIMAL(10,2),
+    sales_date DATE
+);
+
+-- 插入示例销售数据
+INSERT INTO store_sales VALUES 
+(1, 125000.50, '2024-06-01'),
+(2, 98000.00, '2024-06-01'),
+(3, 156000.75, '2024-06-01'),
+(4, 87000.25, '2024-06-01'),
+(5, 76000.00, '2024-06-01'),
+(6, 134000.80, '2024-06-01'),
+(7, 145000.60, '2024-06-01'),
+(8, 93000.40, '2024-06-01');
+
+-- 按服务区域统计销售额
+SELECT 
+    a.area_name,
+    a.area_type,
+    COUNT(DISTINCT s.store_id) as store_count,
+    SUM(sales.sales_amount) as total_sales,
+    AVG(sales.sales_amount) as avg_sales_per_store
+FROM 
+    service_areas a
+    LEFT JOIN store_locations s
+    ON public.ST_Contains(
+        public.ST_GeomFromText(a.boundary), 
+        public.ST_GeomFromText(s.location)
+    ) = true
+    LEFT JOIN store_sales sales
+    ON s.store_id = sales.store_id
+GROUP BY a.area_name, a.area_type
+ORDER BY total_sales DESC;
+```
+
+### 场景 5：坐标提取与转换
+
+提取和转换坐标信息，用于与其他系统集成。
+
+```
+-- 提取所有门店的经纬度坐标
+SELECT 
+    store_id,
+    store_name,
+    city,
+    public.ST_X(public.ST_GeomFromText(location)) as longitude,
+    public.ST_Y(public.ST_GeomFromText(location)) as latitude,
+    location as wkt_format
+FROM 
+    store_locations
+ORDER BY city, store_name;
+
+-- 创建点并立即提取坐标（用于数据验证）
+SELECT 
+    public.ST_X(public.ST_Point(116.397, 39.908)) as x_coord,
+    public.ST_Y(public.ST_Point(116.397, 39.908)) as y_coord;
+```
+
+## 性能优化建议
+
+### 1. 使用物化视图缓存几何体转换结果
+
+```
+-- 创建物化视图，预先转换 WKT 为二进制几何体
+CREATE MATERIALIZED VIEW mv_store_locations AS
+SELECT 
+    store_id,
+    store_name,
+    location as location_wkt,
+    public.ST_GeomFromText(location) as location_geom,
+    city,
+    store_type
+FROM 
+    store_locations;
+
+-- 使用物化视图进行查询（性能更好）
+SELECT 
+    s.store_name,
+    a.area_name
+FROM 
+    mv_store_locations s
+    JOIN service_areas a
+    ON public.ST_Contains(
+        public.ST_GeomFromText(a.boundary), 
+        s.location_geom
+    ) = true;
+```
+
+### 2. 批量处理地理数据
+
+```
+-- 批量判断多个点是否在区域内
+WITH test_points AS (
+    SELECT 1 as id, 'POINT(116.400 39.910)' as location
+    UNION ALL
+    SELECT 2, 'POINT(121.470 31.230)'
+    UNION ALL
+    SELECT 3, 'POINT(114.060 22.540)'
+)
+SELECT 
+    p.id,
+    p.location,
+    a.area_name,
+    public.ST_Contains(
+        public.ST_GeomFromText(a.boundary),
+        public.ST_GeomFromText(p.location)
+    ) as is_inside
+FROM 
+    test_points p
+    CROSS JOIN service_areas a
+WHERE 
+    public.ST_Contains(
+        public.ST_GeomFromText(a.boundary),
+        public.ST_GeomFromText(p.location)
+    ) = true;
+```
+
+## 注意事项
+
+1.  **坐标系**：默认使用 WGS84 坐标系（经纬度），距离单位为度。
+
+2.  **精度说明**：基于经纬度（WGS84）的距离计算是球面近似值，精确计算通常需要投影转换。
+
+3.  **性能考虑**：
+    * 大数据量查询时，可先用边界框（Envelope）进行粗筛。
+    * 频繁使用的几何体转换结果建议缓存。
+    * 复杂多边形运算比简单点运算消耗更多计算资源。
+
+## 故障排查
+
+### 常见错误及解决方案
+
+1. **函数未找到错误**
+
+   ```
+   错误: function not found - ST_Contains解决: 使用 public.ST_Contains
+   ```
+
+2. **几何体格式错误**
+
+   ```
+   错误: Invalid WKT format ; 解决: 检查 WKT 格式是否正确，多边形必须闭合
+   ```
+
+3. **JAR 包路径错误**
+
+   ```
+   错误: Cannot find jar file, 解决: 使用 LIST USER VOLUME 确认文件路径
+   ```

+# 通过样例数据集开始TPCH查询
+
+## 概述
+
+通过本教程，您将了解如何利用 Lakehouse 平台内置的样例数据集，无需提前准备数据即可快速使用 SQL 进行查询分析，以评估 SQL 功能及性能。
+
+> 本教程借助 Lakehouse Tutorial，提供了在线教程指南以及脚本导入功能。您可以在登录 Lakehouse Web 控制台后，通过 Lakehouse Tutorial 入口进入教程，并根据在线指南引导完成教程。
+> ![](.topwrite/assets/image_1736854694431.png)
+
+### 导入脚本
+
+打开控制台 Tutorial 页面中的“Lakehouse 教程”，选择“使用样例数据快速开始查询分析”课程。根据页面提示导入本次课程需要的脚本文件。
+
+在“开发”模块查看“Tutorial_Run_TPCH_Queries_USING_SQL”目录。
+![](.topwrite/assets/image_1725286019515.png)
+
+### 样例数据集
+
+样例数据集由云器平台通过名称为 CLICKZETTA_SAMPLE_DATA 的数据集以共享方式开放给所有账户查询。本教程将以其中的 TPC-H 100GB 数据集为例，介绍如何在 Lakehouse 中快速完成 TPC-H 测试集的查询测试，评估处理性能。
+
+### 教程步骤
+
+1.  **环境准备**：通过样例数据集检查原始数据，创建测试使用的计算集群。
+2.  **发起查询**：使用 Studio Web 环境创建 SQL 查询完成 22 个 TPC-H SQL 查询。
+3.  **变更集群大小**：调整集群大小，扩大至之前集群大小的 2 倍。
+4.  **发起查询**：使用调整大小后的集群再次完成 22 个 TPC-H SQL 查询。
+5.  **观察不同集群规格下查询时延的变化**：
+6.  **清理环境**：删除测试使用的计算集群。
+
+通过以上步骤，您将能够评估不同集群规格下 SQL 查询的性能表现。
+
+## 准备工作
+
+首先，登录 Lakehouse Web 控制台并进入指定的工作空间后，可访问数据模块，检查数据管理下的数据对象列表中“clickzetta_sample_data.tpch_100g”下的相关表是否存在。
+![](.topwrite/assets/image_1716285499384.png)
+
+其次，我们将为本次测试临时创建一个独立计算集群用于查询分析。您可以通过访问 Lakehouse Web 控制台的“计算 → 集群”菜单，通过页面向导新建集群。
+![](.topwrite/assets/tpch_100g_vc.png)
+
+同时，您也可以通过 SQL 命令来创建集群。通过 SQL 命令操作时，您可以不离开 SQL 开发上下文，在 Ad-hoc 或者 ETL 开发过程中通过 SQL 命令控制集群创建、扩/缩容、暂停/恢复、销毁等动作，往往可以提高计算资源的操作效率。
+
+本教程通过在“开发”模块运行 [Tutorials/Tutorial_Run_TPCH_Queries_USING_SQL/Step01.Preparation] SQL 脚本任务，创建分析 TPC-H 数据集所需使用的计算集群。
+![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tu_tpch_vc01.png?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=1880885164\&Signature=wYmSy3IVRKBT7mWtGhuKwT%2BwufQ%3D)
+
+## 对样例数据进行TPC-H的查询
+
+在“开发”模块打开 [Tutorials/Tutorial_Run_TPCH_Queries_USING_SQL/Step02.Run_TPCH_Queries] SQL 脚本文件，将看到 TPC-H 的 22 个查询语句已录入。在[集群]下拉列表中选择刚才创建的测试集群，然后选中任务中的全部脚本，点击[运行]按钮进行串行查询。
+![](.topwrite/assets/image_1725354834261.png)
+
+执行完毕后，可通过当前 SQL Editor 的运行历史查看本次任务的运行耗时。
+
+如果您希望进行性能测试，可连续执行 2 次以上的查询，以便计算集群能够充分缓存（Cache）数据，发挥最佳性能。以下是第二次运行，计算集群缓存（Cache）数据后的运行结果，较第一次无缓存（Cache）时性能有明显提升。

+
+或者在 SQL 脚本中执行以下命令进行修改：
+

+新扩容的计算节点充分缓存（Cache）数据后，性能会继续提升。
+通过作业的运行时间可以观察到，对于相同的数据规模和查询任务，扩大计算集群规格后，任务的总体运行时间大为缩短。两次执行后，随着数据被缓存，查询性能能得到提升。

+# 使用虚拟集群加工和分析数据
+
+## 教程概述
+
+通过本教程，您将了解到如何使用虚拟集群（Virtual Cluster）对纽约出租车公开数据集 Fhvhv trips 原始数据进行清洗转换、聚合加工，并对结果数据进行多并发查询。
+
+教程案例如下图所示：
+![](.topwrite/assets/image_1714992137097.png)
+
+本教程包含以下步骤：
+
+* 环境准备：通过样例数据集检查原始数据，创建计算集群和目标 Schema
+* 数据转换：通过通用型集群清洗、聚合数据用于后续分析
+* Ad-hoc分析：使用Studio Web环境进行单并发SQL查询分析
+* 并发分析：通过Python任务模拟来自Dashboard的连续多并发查询
+
+### 入门知识
+
+什么是虚拟计算集群（Virtual Cluster）？
+
+虚拟计算集群（Virtual Cluster，简称 VC 或集群）是云器 Lakehouse 提供数据处理和分析的计算资源对象。虚拟计算集群提供在Lakehouse中执行SQL作业所需的CPU、内存、本地临时存储（SSD介质）等资源。集群具备快速创建/销毁、扩容/缩容、暂停/恢复等特点，按照资源规格大小以及使用时长进行收费，暂停或删除后不产生费用。
+
+虚拟计算集群针对 ETL 和分析场景，提供通用型和分析型两种集群类型，以满足不同负载之间的隔离和优化需求。
+
+如下图所示：
+![](.topwrite/assets/image_1714992266569.png)
+建议使用通用型集群进行 ETL 数据加工，使用分析型集群进行查询分析或支持数据产品应用。通用型集群支持纵向伸缩，满足不同规模的 ETL Pipeline 任务需要。分析型集群支持集群内多副本（Replica）的横向伸缩，以满足并发查询的弹性需求。
+
+本教程将分别使用通用型集群进行数据清洗转换，使用分析型集群进行低延迟的并发分析。
+
+### 教程目标
+
+* 创建和使用虚拟计算集群用于不同业务负载
+* 了解和使用分析型集群的弹性并发功能
+
+## Step01 检查原始数据
+
+1. 创建虚拟集群
+
+分别创建通用型（GENERAL PURPOSE）和分析型（ANALYTICS）集群，用于 ETL 加工和查询分析，实现负载隔离。
+
+```sql
+-- 1.1 创建面向ETL处理的虚拟集群
+CREATE VCLUSTER ETL_VC 
+VCLUSTER_SIZE = MEDIUM 
+VCLUSTER_TYPE = GENERAL 
+AUTO_SUSPEND_IN_SECOND = 60 
+AUTO_RESUME = TRUE;
+
+-- 1.2 创建面向BI分析的虚拟集群，设置弹性并发以支持多并发查询
+CREATE VCLUSTER REPORTING_VC 
+VCLUSTER_SIZE = XSMALL 
+VCLUSTER_TYPE = ANALYTICS
+MIN_REPLICAS = 1
+MAX_REPLICAS = 4
+MAX_CONCURRENCY = 8
+AUTO_SUSPEND_IN_SECOND = 300 
+AUTO_RESUME = TRUE ;
+
+-- 1.3 查看集群资源
+show  vclusters ;
+
+-- 1.4 切换当前Session下使用的虚拟集群,要和执行的SQL一起选中执行才会生效
+USE VCLUSTER REPORTING_VC;
+```
+
+![](.topwrite/assets/image_1714992453071.png)
+
+> 注：计算集群的 `vcluster_size` 参数同时支持 T-shirt size（XSMALL、SMALL、LARGE 等）和数字（1, 2, 4, 16 等）两种表达方式，以提供更丰富的计算集群规格，满足不同场景的需要。更多信息详见：[计算集群规格代码变更说明](vcluster_size_description.md)
+
+^
+
+2. 查看公共数据集中的原始数据
+
+2.1 查看原始数据的字段信息。
+
+```sql
+--Describes New York City For-Hire-Vehicle trips. 
+desc clickzetta_sample_data.nyc_taxi_tripdata.fhvhv_tripdata;
+```
+
+![](.topwrite/assets/image_1714992471693.png)
+
+2.2 预览数据明细
+
+```sql
+--Sample Of Trip Record Data
+select * from clickzetta_sample_data.nyc_taxi_tripdata.fhvhv_tripdata limit 10;
+```
+
+![](.topwrite/assets/image_1714992501025.png)
+
+2.3 查看数据集的记录数
+
+```sql
+--1.49 billion rows
+select count(*) from clickzetta_sample_data.nyc_taxi_tripdata.fhvhv_tripdata;
+```
+
+## Step02 使用通用型集群清洗转换数据
+
+1. 指定使用 `ETL_VC` 进行数据加工，同时创建目标表所在的 Schema
+
+```sql
+--要和执行的SQL一起选中执行才会生效
+use vcluster ETL_VC;
+create schema tutorial;
+use tutorial;
+```
+
+2. 通过 CTAS 对原始数据集进行清洗转换并写入新表
+
+```sql
+--2.对原始数据集进行清洗转换
+CREATE table tutorial.int_fhvhv_tripdata
+as
+SELECT
+  hvfhs_license_num,
+  CASE 
+    WHEN hvfhs_license_num = 'HV0002' THEN 'juno'
+    WHEN hvfhs_license_num = 'HV0003' THEN 'uber'
+    WHEN hvfhs_license_num = 'HV0004' THEN 'via'
+    WHEN hvfhs_license_num = 'HV0005' THEN 'lyft'
+    ELSE null
+  END AS company,
+  ltrim(rtrim(upper(dispatching_base_num))) dispatching_base_num,
+  ltrim(rtrim(upper(originating_base_num))) originating_base_num,
+  request_datetime,
+  on_scene_datetime,
+  pickup_datetime,
+  dropoff_datetime,
+  PULocationID,
+  DOLocationID,
+  trip_miles,
+  trip_time,
+  base_passenger_fare,
+  tolls,
+  bcf,
+  sales_tax,
+  congestion_surcharge,
+  airport_fee,
+  tips,
+  driver_pay,
+  CASE
+    WHEN shared_request_flag = 'Y' THEN true
+    WHEN shared_request_flag IN ('N', ' ') THEN false
+    ELSE null
+  END AS shared_request_flag,
+  CASE
+    WHEN shared_match_flag = 'Y' THEN true
+    WHEN shared_match_flag IN ('N', ' ') THEN false
+    ELSE null
+  END AS shared_match_flag,
+  CASE
+    WHEN access_a_ride_flag = 'Y' THEN true
+    WHEN access_a_ride_flag IN ('N', ' ') THEN false
+    ELSE null
+  END AS access_a_ride_flag,
+  CASE
+    WHEN wav_request_flag = 'Y' THEN true
+    WHEN wav_request_flag IN ('N', ' ') THEN false
+    ELSE null
+  END AS wav_request_flag,
+  CASE
+    WHEN wav_match_flag = 'Y' THEN true
+    WHEN wav_match_flag IN ('N', ' ') THEN false
+    ELSE null
+  END AS wav_match_flag
+FROM clickzetta_sample_data.nyc_taxi_tripdata.fhvhv_tripdata;
+```
+
+验证加工后的数据
+
+```sql
+SELECT * FROM tutorial.int_fhvhv_tripdata LIMIT 10;
+```
+
+![](.topwrite/assets/image_1714992818566.png)
+
+3. 对清洗后的数据按照分析主题分别进行聚合计算，生成用于分析的数据表。
+
+```sql
+--Scenario 1: Analyze taxi trip patterns by time of day
+CREATE table tutorial.mart_trips_pattern_by_time
+AS
+SELECT
+  EXTRACT(HOUR FROM pickup_datetime) AS hour,
+  COUNT(*) AS trip_count
+FROM tutorial.int_fhvhv_tripdata
+GROUP BY hour;
+
+--Scenario 2: Analyze taxi trip patterns by day of the week
+CREATE table tutorial.mart_trips_pattern_by_dayofweek
+AS
+SELECT
+  EXTRACT(DAY FROM pickup_datetime) AS day_of_week,
+  COUNT(*) AS trip_count
+FROM tutorial.int_fhvhv_tripdata
+GROUP BY day_of_week;
+
+--Scenario 3: Analyze taxi trip patterns by pickup location
+CREATE table tutorial.mart_trips_pattern_by_pickup_location
+AS
+SELECT
+  PULocationID,
+  COUNT(*) AS trip_count
+FROM tutorial.int_fhvhv_tripdata
+GROUP BY PULocationID;
+
+--Scenario 4: Analyze taxi trip patterns by dropoff location
+CREATE table tutorial.mart_trips_pattern_by_dropoff_location
+AS
+SELECT
+  DOLocationID,
+  COUNT(*) AS trip_count
+FROM tutorial.int_fhvhv_tripdata
+GROUP BY DOLocationID;
+
+--Scenario 5:Trips per day
+CREATE table tutorial.mart_trips_per_day
+AS
+SELECT
+  pickup_datetime::date AS date,
+  sum(trip_miles) AS trip_miles
+FROM tutorial.int_fhvhv_tripdata
+GROUP BY date;
+
+--Scenario 6:Total driver pay per company
+CREATE table tutorial.mart_trips_driver_pay_per_company
+AS
+SELECT
+  CONCAT(YEAR(pickup_datetime), '-', MONTH(pickup_datetime)) AS year_month,
+  company,
+  sum(driver_pay) AS driver_pay
+FROM tutorial.int_fhvhv_tripdata
+GROUP BY year_month,company;
+```
+
+检查数据对象是否创建成功。
+
+```sql
+--检查新创建数据模型的状态
+show tables in tutorial;
+```
+
+![](.topwrite/assets/image_1714992844915.png)
+
+```sql
+--检查新创建数据模型的数据
+SELECT * FROM tutorial.mart_trips_driver_pay_per_company
+WHERE substr(year_month,0,4)='2021'
+ORDER BY year_month ASC;
+```
+
+![](.topwrite/assets/image_1714992852747.png)
+
+## Step03 使用分析型集群单并发查询
+
+1. 切换当前 Session 使用的虚拟集群为 REPORTING_VC。
+
+```sql
+-- 1.使用分析型VC进行加速查询分析，要和执行的SQL一起选中执行才会生效
+USE VCLUSTER REPORTING_VC;
+--设置查询作业标签，以便检索过滤，要和执行的SQL一起选中执行才会生效
+SET QUERY_TAG = 'Tutorial02';
+```
+
+2. 串行执行 6 个业务分析查询。
+
+```sql
+--Scenario 1: Analyze taxi trip patterns by time of day
+SELECT * FROM tutorial.mart_trips_pattern_by_time
+ORDER BY HOUR ASC;
+
+--Scenario 2: Analyze taxi trip patterns by day of the week
+SELECT * FROM tutorial.mart_trips_pattern_by_dayofweek
+ORDER BY day_of_week ASC;
+
+--Scenario 3: Analyze taxi trip patterns by pickup location
+SELECT * FROM tutorial.mart_trips_pattern_by_pickup_location
+ORDER BY trip_count DESC
+LIMIT 10;
+
+--Scenario 4: Analyze taxi trip patterns by dropoff location
+SELECT * FROM tutorial.mart_trips_pattern_by_dropoff_location
+ORDER BY trip_count DESC
+LIMIT 10;
+
+--Scenario 5:Trips per day
+SELECT * FROM tutorial.mart_trips_per_day
+WHERE CONCAT(YEAR(date) , MONTH(date)) = '202110'
+ORDER BY date;
+
+--Scenario 6:Total driver pay per company
+SELECT * FROM tutorial.mart_trips_driver_pay_per_company
+WHERE substr(year_month,0,4)='2021'
+ORDER BY year_month ASC;
+```
+
+3. 观察查询的 Latency 结果。
+
+```sql
+--清除QUERY_TAG
+SET QUERY_TAG = '';
+--查看运行的作业执行结果
+SHOW JOBS WHERE QUERY_TAG='Tutorial02' LIMIT 10;
+```
+
+您还可以使用 Studio 页面的作业历史功能查看查询作业的执行情况。

+
+## Step04 使用Python任务并发查询
+
+通过Python任务进行并发查询测试，查看分析型集群在连续的动态并发查询下的性能表现以及弹性扩展能力。
+
+1. 在 Studio 开发模块中，创建 Python 任务。
+   ![](.topwrite/assets/image_1714992974205.png)
+
+2. 通过 Lakehouse Python SDK 编写并发测试脚本
+
+本教程的脚本实现了以下处理逻辑：
+
+* 创建 Lakehouse 服务实例连接，指定工作空间、计算集群名称。
+* 通过提交连续、梯度增加的并发查询，模拟多用户发起的 Dashboard 查询。
+* 收集并打印并发查询下的 Latency 以及计算资源的弹性扩容状态变化。
+
+```python
+# Step 04: 使用Studio Python任务进行并发查询
+# 操作步骤：
+# 1.创建Lakehouse服务实例连接，指定工作空间、计算集群名称
+# 2.通过提交连续、梯度增加并发查询来模拟多用户发起的Dashboard查询
+# 3.观察连续并发查询下，分析型计算集群的动态弹性并发能力

+```
+
+当设置 reporting_vc 的单 Replica 最大并发数为 4 时，打印结果示例如下：
+
+* --Running with 4 concurrent queries:--- Total Queries: 120 Average Latency: 0.2201933761437734 P95 Latency: 0.43064022064208984 P99 Latency: 0.683488130569458 Queries per Second (QPS): 4.5414626793635176 ('current_replicas', '1') ---Running with 8 concurrent queries:--- Total Queries: 240 Average Latency: 0.20615292688210804 P95 Latency: 0.2397170066833496 P99 Latency: 0.4295358657836914 Queries per Second (QPS): 4.850767898977571 ('current_replicas', '2') ---Running with 12 concurrent queries:--- Total Queries: 360 Average Latency: 0.2232776681582133 P95 Latency: 0.27333879470825195 P99 Latency: 0.46774768829345703 Queries per Second (QPS): 4.478728250115035 ('current_replicas', '3') ---Running with 16 concurrent queries:--- Total Queries: 480 Average Latency: 0.23430742422739664 P95 Latency: 0.25676393508911133 P99 Latency: 0.4392051696777344 Queries per Second (QPS): 4.267897200856488 ('current_replicas', '4')
+
+客户端分别模拟 4、8、12、16 四轮并发查询，每轮每个并发连续提交 30 次查询。可以观察到 `reporting_vc` 会根据客户端并发度动态增加副本（Replica）数量，在用户无感知集群动态扩容的前提下，保证不同并发数量下平均时延、P95、P99、QPS 指标保持稳定。

+# GRANT TO SHARE 语句
+
+## 功能描述
+
+`GRANT TO SHARE` 语句的主要功能是将指定的表（table）或视图（view）添加到一个已存在的分享对象（share）中，并授予相应的权限。通过使用该语句，用户可以方便地对数据进行共享和管理，同时确保数据的安全性和可访问性。
+
+仅支持将表（table）或视图（view）添加到类型（kind属性）为'OUTBOUND'（对外分享）的分享对象中。其他服务实例分享进入的分享对象（share）不可添加数据对象。
+
+## 语法格式
+
+```SQL
+GRANT select, read metadata ON {TABLE <table_name> | VIEW <view_name>} TO SHARE <share_name>;
+```
+
+**参数说明**
+
+1. **share_name**：需要操作的分享对象名称。
+2. **table_name**：需要添加到分享对象中的表名称。
+3. **view_name**：需要添加到分享对象中的视图名称。
+4. **select, read metadata**：需要授予分享对象的权限点。`select` 权限允许对被分享的数据进行查询操作；`read metadata` 权限使得加入分享对象的表和视图的元数据对被分享方可见。当授予表或视图的 `read metadata` 权限时，其所属的模式（schema）的 `read metadata` 权限也将自动被授予至分享对象，以实现表和视图对被分享方的可见性。
+
+## 使用示例
+
+**示例 1：指定表进行分享**
+
+假设我们有一个名为 `share_demo` 的分享对象，以及一个名为 `share_demo_table` 的表。我们希望将 `share_demo_table` 表添加到 `share_demo` 分享对象中，并授予 `select` 和 `read metadata` 权限。可以使用以下语句实现：
+
+```SQL
+GRANT select, read metadata ON TABLE share_demo_table TO SHARE share_demo;
+```
+
+**示例 2：指定视图进行分享**
+
+在这个示例中，我们有一个名为 `share_demo` 的分享对象和一个名为 `share_demo_view` 的视图。我们希望将 `share_demo_view` 视图添加到 `share_demo` 分享对象中，并授予相应的权限。可以使用以下语句：
+
+```SQL
+GRANT select, read metadata ON VIEW share_demo_view TO SHARE share_demo;
+```
+
+**示例 3：同时分享多个表和视图**
+
+有时，我们可能需要将多个表和视图添加到分享对象中。此时需要多次执行 GRANT 语句，每个 GRANT 语句将其中一个数据对象加入到指定的 share 对象中。以下示例展示了如何将 `share_demo_table1`、`share_demo_table2` 和 `share_demo_view` 添加到 `share_demo` 分享对象中，并授予相应的权限：
+
+```SQL
+GRANT select, read metadata ON TABLE share_demo_table1, share_demo_table2 TO SHARE share_demo;
+GRANT select, read metadata ON VIEW share_demo_view TO SHARE share_demo;
+```
+
+## 注意事项
+
+1. 在执行 `GRANT TO SHARE` 语句之前，请确保分享对象（share）已经存在。
+2. 仅当您具备该对象的 select 和 read metadata 权限，并可将该权限做二次授权时，才可将该对象添加至数据分享对象中。
+3. 当分享表或视图时，请确保充分考虑数据的安全性和可访问性，以避免不必要的风险。

+
+--schema下对象授权
+schemaObjectPriveleges ::=
+    -- table
+   ALTER | DROP | SELECT | INSERT | READ METADATA | ALL
+    -- view
+   ALTER | DROP | SELECT  | ALL
+    -- MATERIALIZED VIEW
+   ALTER | DROP | SELECT | ALL 
+```
+
+参数说明
+
+**1.workspacePriveleges**
+workspace下创建对象的权限如CREATE VCLUSTER
+
+**2.workspaceObjectPriveleges**
+workspace下对象的修改和show权限
+
+**3.schemaPrivileges**
+schema下创建对象的权限
+
+**4.schemaObjectPriveleges**
+schema下对象表修改、表删除、表查询等权限
+
+### - 将指定权限授予某用户
+
+```
+GRANT ROLE role_name TO USER user_name;
+```
+
+## 参数说明
+
+1. `workspacePrivileges`：在 workspace 下创建对象的权限，例如 `CREATE SCHEMA`、`CREATE VCLUSTER` 等。
+2. `workspaceObjectPrivileges`：在 workspace 下对象的修改和查询权限，例如 `ALTER`、`DROP`、`READ METADATA` 等。
+3. `schemaPrivileges`：在 schema 下创建对象的权限，例如 `CREATE TABLE`、`CREATE VIEW`、`CREATE MATERIALIZED VIEW` 等。
+4. `schemaObjectPrivileges`：在 schema 下对象的修改、查询等权限，例如 `ALTER`、`DROP`、`SELECT` 等。
+5. `role_name`：角色名称，支持自定义角色和系统默认角色。系统默认角色包括 `system_admin`、`user_admin`、`security_admin`、`audit_admin` 等。
+6. `username`：用户名称。
+7. `WITH GRANT OPTION`：表示被授权的用户可以将这些权限再授权给其他用户。
+
+## 使用示例
+
+1. 授权给用户 `uat_demo` 在 `lakehouse_public` workspace 下创建 `VIRTUAL CLUSTER` 权限：
+   ```SQL
+   GRANT CREATE VCLUSTER ON WORKSPACE lakehouse_public TO USER uat_demo;
+   ```
+
+2. 授权给用户 `uat_demo` 修改名为 `default` 的 `VIRTUAL CLUSTER` 权限：
+   ```SQL
+   GRANT ALTER VCLUSTER ON VCLUSTER default TO USER  uat_demo;
+   ```
+
+3. 授权给用户 `uat_demo` 在 `public` schema 下创建表和视图的权限：
+   ```SQL
+   GRANT CREATE TABLE, CREATE VIEW ON SCHEMA public TO USER uat_demo;
+   ```
+
+4. 授权给用户 `uat_demo` 查询 `public` schema 下所有表和视图的权限：
+   ```SQL
+   GRANT SELECT ON ALL TABLES IN SCHEMA public TO USER uat_demo;
+   ```
+
+5. 授权给角色 `user_admin` 的用户 `uat_demo` 在 `lakehouse_public` workspace 下的 `security` schema 下创建表和视图的权限：
+   ```SQL
+   GRANT CREATE TABLE, CREATE VIEW ON SCHEMA security TO ROLE user_admin;
+   ```
+
+通过以上示例，您可以根据实际需求灵活地为用户或角色分配相应的权限。请确保在授权时遵循最小权限原则，以降低安全风险。

+# GROUP BY
+
+## 概述
+
+`GROUP BY` 子句是 SQL 查询中用于数据分组和聚合分析的核心组件。通过 `GROUP BY`，可以将数据集按照指定的列或表达式进行分组，并对每个分组应用聚合函数（如 `SUM()`、`COUNT()`、`AVG()`、`MAX()`、`MIN()` 等）计算汇总值。
+
+云器 Lakehouse 完整支持标准 SQL GROUP BY 语法，并提供高级聚合能力：
+
+| 功能                | 说明         | 应用场景           |
+| ----------------- | ---------- | -------------- |
+| **标准 GROUP BY**   | 基础分组聚合     | 日常统计、基础报表      |
+| **GROUPING SETS** | 自定义多个分组集合  | 多维度业务分析        |
+| **ROLLUP**        | 层级汇总（从细到总） | 财务报表、销售层级分析    |
+| **CUBE**          | 全维度交叉分析    | BI 多维数据透视、交叉分析 |
+
+***
+
+## 语法结构
+
+```sql
+SELECT 
+    column1,
+    column2,
+    aggregate_function(column3) AS alias
+FROM table_name
+WHERE condition
+GROUP BY 
+    [ group_expression [, group_expression, ...] |
+      GROUPING SETS (grouping_set [, grouping_set, ...]) |
+      ROLLUP(expression [, expression, ...]) |
+      CUBE(expression [, expression, ...]) ]
+HAVING aggregate_condition
+ORDER BY column
+LIMIT n;
+```
+
+### 关键要点
+
+1. **SELECT 子句约束**：SELECT 列表中的非聚合列必须出现在 GROUP BY 子句中
+2. **执行顺序**：FROM → WHERE → GROUP BY → HAVING → SELECT → ORDER BY → LIMIT
+3. **HAVING 过滤**：用于过滤聚合结果，而 WHERE 过滤原始行
+4. **NULL 值处理**：NULL 被视为一个独立的分组
+
+***
+
+## 准备测试数据
+
+本文档使用汽车经销商销售数据作为示例。创建测试视图：
+
+```sql
+CREATE OR REPLACE VIEW dealer (id, city, car_model, quantity) AS
+VALUES 
+    (100, 'Fremont', 'Honda Civic', 10),
+    (100, 'Fremont', 'Honda Accord', 15),
+    (100, 'Fremont', 'Honda CRV', 7),
+    (200, 'Dublin', 'Honda Civic', 20),
+    (200, 'Dublin', 'Honda Accord', 10),
+    (200, 'Dublin', 'Honda CRV', 3),
+    (300, 'San Jose', 'Honda Civic', 5),
+    (300, 'San Jose', 'Honda Accord', 8);
+```
+
+查看原始数据：
+
+```sql
+SELECT * FROM dealer ORDER BY id, car_model LIMIT 50;
+```
+
+**查询结果**：
+
+| id  | city     | car\_model   | quantity |
+| --- | -------- | ------------ | -------- |
+| 100 | Fremont  | Honda Accord | 15       |
+| 100 | Fremont  | Honda CRV    | 7        |
+| 100 | Fremont  | Honda Civic  | 10       |
+| 200 | Dublin   | Honda Accord | 10       |
+| 200 | Dublin   | Honda CRV    | 3        |
+| 200 | Dublin   | Honda Civic  | 20       |
+| 300 | San Jose | Honda Accord | 8        |
+| 300 | San Jose | Honda Civic  | 5        |
+
+***
+
+## 一、标准 GROUP BY
+
+### 1.1 单列分组
+
+按经销商 ID 分组，统计每个经销商的销量：
+
+```sql
+SELECT 
+    id, 
+    SUM(quantity) AS total_quantity
+FROM dealer
+GROUP BY id
+ORDER BY id
+LIMIT 50;
+```
+
+**查询结果**：
+
+| id  | total\_quantity |
+| --- | --------------- |
+| 100 | 32              |
+| 200 | 33              |
+| 300 | 13              |
+
+**业务解读**：
+
+*   经销商 100（Fremont）销售了 32 辆车
+*   经销商 200（Dublin）销售了 33 辆车
+*   经销商 300（San Jose）销售了 13 辆车
+
+***
+
+### 1.2 多列分组
+
+按城市和车型的组合进行分组统计：
+
+```sql
+SELECT 
+    id, 
+    city, 
+    SUM(quantity) AS total_quantity
+FROM dealer
+GROUP BY id, city
+ORDER BY total_quantity DESC
+LIMIT 50;
+```
+
+**查询结果**：
+
+| id  | city     | total\_quantity |
+| --- | -------- | --------------- |
+| 200 | Dublin   | 33              |
+| 100 | Fremont  | 32              |
+| 300 | San Jose | 13              |
+
+在本示例中，每个经销商 ID 对应唯一的城市，因此结果与单列分组相同。
+
+***
+
+### 1.3 使用表达式分组
+
+使用 `CASE` 表达式对销量进行分段统计：
+
+```sql
+SELECT 
+    CASE 
+        WHEN quantity < 10 THEN 'Low (< 10)'
+        WHEN quantity < 15 THEN 'Medium (10-14)'
+        ELSE 'High (>= 15)'
+    END AS sales_level,
+    COUNT(*) AS record_count,
+    SUM(quantity) AS total_quantity
+FROM dealer
+GROUP BY 
+    CASE 
+        WHEN quantity < 10 THEN 'Low (< 10)'
+        WHEN quantity < 15 THEN 'Medium (10-14)'
+        ELSE 'High (>= 15)'
+    END
+ORDER BY sales_level
+LIMIT 50;
+```
+
+**查询结果**：
+
+| sales\_level   | record\_count | total\_quantity |
+| -------------- | ------------- | --------------- |
+| High (>= 15)   | 2             | 35              |
+| Low (< 10)     | 4             | 23              |
+| Medium (10-14) | 2             | 20              |
+
+**业务解读**：
+
+* 高销量记录（≥15 辆）：2 条记录，共 35 辆
+* 低销量记录（<10 辆）：4 条记录，共 23 辆
+* 中等销量记录（10-14 辆）：2 条记录，共 20 辆
+
+***
+
+### 1.4 全局聚合（无分组）
+
+不使用 GROUP BY 时，对整个表进行全局聚合：
+
+```sql
+SELECT SUM(quantity) AS total_quantity 
+FROM dealer
+LIMIT 50;
+```
+
+**查询结果**：
+
+| total\_quantity |
+| --------------- |
+| 78              |
+
+全部 8 条记录的总销量为 78 辆。
+
+***
+
+## 二、多聚合函数组合
+
+### 2.1 常用聚合函数汇总
+
+在单次查询中使用多个聚合函数：
+
+```sql
+SELECT 
+    city,
+    COUNT(*) AS model_count,
+    SUM(quantity) AS total_quantity,
+    AVG(quantity) AS avg_quantity,
+    MAX(quantity) AS max_quantity,
+    MIN(quantity) AS min_quantity
+FROM dealer
+GROUP BY city
+ORDER BY total_quantity DESC
+LIMIT 50;
+```
+
+**查询结果**：
+
+| city     | model\_count | total\_quantity | avg\_quantity      | max\_quantity | min\_quantity |
+| -------- | ------------ | --------------- | ------------------ | ------------- | ------------- |
+| Dublin   | 3            | 33              | 11.0               | 20            | 3             |
+| Fremont  | 3            | 32              | 10.666666666666666 | 15            | 7             |
+| San Jose | 2            | 13              | 6.5                | 8             | 5             |
+
+**业务洞察**：
+
+* **Dublin**：3 个车型，平均每个车型销售 11 辆，最高单品 20 辆（Honda Civic）
+* **Fremont**：3 个车型，平均销量 10.67 辆，销量较均衡
+* **San Jose**：仅 2 个车型，平均销量 6.5 辆，市场规模最小
+
+***
+
+### 2.2 按车型统计覆盖城市数
+
+统计每个车型在多少个城市有销售：
+
+```sql
+SELECT 
+    car_model,
+    SUM(quantity) AS total_sales,
+    COUNT(DISTINCT city) AS city_count,
+    ROUND(AVG(quantity), 2) AS avg_per_dealer
+FROM dealer
+GROUP BY car_model
+ORDER BY total_sales DESC
+LIMIT 50;
+```
+
+**查询结果**：
+
+| car\_model   | total\_sales | city\_count | avg\_per\_dealer |
+| ------------ | ------------ | ----------- | ---------------- |
+| Honda Civic  | 35           | 3           | 11.67            |
+| Honda Accord | 33           | 3           | 11.00            |
+| Honda CRV    | 10           | 2           | 5.00             |
+
+**业务洞察**：
+
+* **Honda Civic**：最畅销车型，总销量 35 辆，覆盖 3 个城市，平均每地 11.67 辆
+* **Honda Accord**：总销量 33 辆，覆盖 3 个城市
+* **Honda CRV**：总销量最低，仅在 2 个城市有销售（未进入 San Jose 市场）
+
+***
+
+## 三、GROUPING SETS（自定义分组集合）
+
+### 3.1 基本概念
+
+`GROUPING SETS` 允许在一次查询中同时生成多个不同维度的分组结果。它本质上是多个 `GROUP BY` 查询通过 `UNION ALL` 组合的简写形式。
+
+**语法**：
+
+```sql
+GROUP BY GROUPING SETS (
+    (column1, column2),  -- 分组集1：按 column1 和 column2 分组
+    (column1),           -- 分组集2：仅按 column1 分组
+    ()                   -- 分组集3：全局聚合（无分组）
+)
+```
+
+***
+
+### 3.2 多维度聚合分析
+
+在一次查询中生成四个维度的统计结果：
+
+```sql
+SELECT 
+    city, 
+    car_model, 
+    SUM(quantity) AS total_quantity
+FROM dealer
+GROUP BY GROUPING SETS (
+    (city, car_model),  -- 城市+车型明细
+    (city),             -- 按城市汇总
+    (car_model),        -- 按车型汇总
+    ()                  -- 总计
+)
+ORDER BY city, car_model
+LIMIT 50;
+```
+
+**查询结果**：
+
+| city     | car\_model   | total\_quantity |
+| -------- | ------------ | --------------- |
+| NULL     | NULL         | 78              |
+| NULL     | Honda Accord | 33              |
+| NULL     | Honda CRV    | 10              |
+| NULL     | Honda Civic  | 35              |
+| Dublin   | NULL         | 33              |
+| Dublin   | Honda Accord | 10              |
+| Dublin   | Honda CRV    | 3               |
+| Dublin   | Honda Civic  | 20              |
+| Fremont  | NULL         | 32              |
+| Fremont  | Honda Accord | 15              |
+| Fremont  | Honda CRV    | 7               |
+| Fremont  | Honda Civic  | 10              |
+| San Jose | NULL         | 13              |
+| San Jose | Honda Accord | 8               |
+| San Jose | Honda Civic  | 5               |
+
+**结果解读**：
+
+* **总计行**（city=NULL, car\_model=NULL）：全部销量 78 辆
+* **车型汇总行**（city=NULL, car\_model有值）：各车型跨城市总销量
+* **城市汇总行**（city有值, car\_model=NULL）：各城市跨车型总销量
+* **明细行**（city和car\_model都有值）：城市+车型组合的具体销量
+
+**等价查询**：
+
+```sql
+-- GROUPING SETS 等价于以下 UNION ALL 查询
+SELECT city, car_model, SUM(quantity) FROM dealer GROUP BY city, car_model
+UNION ALL
+SELECT city, NULL, SUM(quantity) FROM dealer GROUP BY city
+UNION ALL
+SELECT NULL, car_model, SUM(quantity) FROM dealer GROUP BY car_model
+UNION ALL
+SELECT NULL, NULL, SUM(quantity) FROM dealer;
+```
+
+**性能优势**：`GROUPING SETS` 在内部只扫描一次数据，比 `UNION ALL` 更高效。
+
+***
+
+### 3.3 识别汇总层级
+
+使用 `COALESCE` 函数替换 NULL 值，使汇总行更易读：
+
+```sql
+SELECT 
+    COALESCE(city, 'All Cities') AS city,
+    COALESCE(car_model, 'All Models') AS car_model,
+    SUM(quantity) AS total_quantity
+FROM dealer
+GROUP BY ROLLUP(city, car_model)
+ORDER BY city, car_model
+LIMIT 50;
+```
+
+**查询结果**：
+
+| city       | car\_model   | total\_quantity |
+| ---------- | ------------ | --------------- |
+| All Cities | All Models   | 78              |
+| Dublin     | All Models   | 33              |
+| Dublin     | Honda Accord | 10              |
+| Dublin     | Honda CRV    | 3               |
+| Dublin     | Honda Civic  | 20              |
+| Fremont    | All Models   | 32              |
+| Fremont    | Honda Accord | 15              |
+| Fremont    | Honda CRV    | 7               |
+| Fremont    | Honda Civic  | 10              |
+| San Jose   | All Models   | 13              |
+| San Jose   | Honda Accord | 8               |
+| San Jose   | Honda Civic  | 5               |
+
+***
+
+## 四、ROLLUP（层级汇总）
+
+### 4.1 基本概念
+
+`ROLLUP` 用于生成从细粒度到全局的层级汇总。对于 `ROLLUP(a, b, c)`，将生成以下分组集：
+
+* `(a, b, c)` - 最细粒度
+* `(a, b)` - 中间层级
+* `(a)` - 高层级
+* `()` - 全局汇总
+
+**等价关系**：
+
+```sql
+ROLLUP(city, car_model) 
+-- 等价于
+GROUPING SETS (
+    (city, car_model),
+    (city),
+    ()
+)
+```
+
+***
+
+### 4.2 销售层级汇总
+
+生成"城市→车型"两级汇总：
+
+```sql
+SELECT 
+    city, 
+    car_model, 
+    SUM(quantity) AS total_quantity 
+FROM dealer
+GROUP BY ROLLUP(city, car_model)
+LIMIT 50;
+```
+
+**查询结果**：
+
+| city     | car\_model   | total\_quantity |
+| -------- | ------------ | --------------- |
+| Fremont  | Honda Civic  | 10              |
+| Fremont  | Honda Accord | 15              |
+| Fremont  | Honda CRV    | 7               |
+| Dublin   | Honda Civic  | 20              |
+| Dublin   | Honda Accord | 10              |
+| Dublin   | Honda CRV    | 3               |
+| San Jose | Honda Civic  | 5               |
+| San Jose | Honda Accord | 8               |
+| Fremont  | NULL         | 32              |
+| Dublin   | NULL         | 33              |
+| San Jose | NULL         | 13              |
+| NULL     | NULL         | 78              |
+
+**数据层级**：
+
+1. **明细层**（前8行）：每个城市的每种车型的销量
+2. **城市小计**（car\_model=NULL）：每个城市的总销量
+3. **总计**（city=NULL, car\_model=NULL）：所有城市的总销量
+
+***
+
+### 4.3 使用 GROUPING() 函数标识层级
+
+`GROUPING()` 函数返回 0 或 1，用于区分真实 NULL 和聚合标记：
+
+* **返回 0**：该列参与分组，值为实际数据
+* **返回 1**：该列未参与分组，NULL 表示汇总
+
+```sql
+SELECT 
+    city,
+    car_model,
+    SUM(quantity) AS total_quantity,
+    GROUPING(city) AS city_grouping,
+    GROUPING(car_model) AS model_grouping
+FROM dealer
+GROUP BY ROLLUP(city, car_model)
+ORDER BY city_grouping, city, model_grouping, car_model
+LIMIT 50;
+```
+

+
+**GROUPING() 值解读**：
+
+* (**0, 0**)：明细数据，两列都参与分组
+* (**0, 1**)：城市小计，仅 city 参与分组
+* (**1, 1**)：全局总计，两列都不参与分组
+
+***
+
+## 五、CUBE（全维度交叉分析）
+
+### 5.1 基本概念
+
+`CUBE` 生成指定列的所有可能组合的分组集。对于 `CUBE(a, b)`，将生成 2² = 4 个分组集：
+
+* `(a, b)` - 明细
+* `(a)` - 按 a 汇总
+* `(b)` - 按 b 汇总
+* `()` - 全局汇总
+
+**等价关系**：
+
+```sql
+CUBE(city, car_model)
+-- 等价于
+GROUPING SETS (
+    (city, car_model),
+    (city),
+    (car_model),
+    ()
+)
+```
+
+***
+
+### 5.2 多维交叉分析
+
+生成城市和车型的所有维度组合：
+
+```sql
+SELECT 
+    city, 
+    car_model, 
+    SUM(quantity) AS total_quantity 
+FROM dealer
+GROUP BY city, car_model WITH CUBE
+LIMIT 50;
+```
+
+**查询结果**：
+
+| city     | car\_model   | total\_quantity |
+| -------- | ------------ | --------------- |
+| Fremont  | Honda Civic  | 10              |
+| Fremont  | Honda Accord | 15              |
+| Fremont  | Honda CRV    | 7               |
+| Dublin   | Honda Civic  | 20              |
+| Dublin   | Honda Accord | 10              |
+| Dublin   | Honda CRV    | 3               |
+| San Jose | Honda Civic  | 5               |
+| San Jose | Honda Accord | 8               |
+| NULL     | Honda CRV    | 10              |
+| NULL     | Honda Civic  | 35              |
+| NULL     | Honda Accord | 33              |
+| Fremont  | NULL         | 32              |
+| Dublin   | NULL         | 33              |
+| San Jose | NULL         | 13              |
+| NULL     | NULL         | 78              |
+
+**结果包含**：
+
+1. **明细行**（前8行）：城市+车型组合
+2. **车型汇总行**（city=NULL）：跨城市的车型销量
+3. **城市汇总行**（car\_model=NULL）：跨车型的城市销量
+4. **总计行**（city=NULL, car\_model=NULL）：全局总计
+
+***
+
+### 5.3 标识聚合层级
+
+使用 `CASE` 语句结合 `GROUPING()` 函数标识每行的聚合层级：
+
+```sql
+SELECT 
+    city,
+    car_model,
+    SUM(quantity) AS total_quantity,
+    CASE 
+        WHEN GROUPING(city) = 1 AND GROUPING(car_model) = 1 THEN 'Total'
+        WHEN GROUPING(city) = 0 AND GROUPING(car_model) = 1 THEN 'City Subtotal'
+        WHEN GROUPING(city) = 1 AND GROUPING(car_model) = 0 THEN 'Model Subtotal'
+        ELSE 'Detail'
+    END AS aggregation_level
+FROM dealer
+GROUP BY CUBE(city, car_model)
+ORDER BY 
+    GROUPING(city),
+    GROUPING(car_model),
+    city,
+    car_model
+LIMIT 50;
+```
+
+**查询结果**：
+
+| city     | car\_model   | total\_quantity | aggregation\_level |
+| -------- | ------------ | --------------- | ------------------ |
+| Dublin   | Honda Accord | 10              | Detail             |
+| Dublin   | Honda CRV    | 3               | Detail             |
+| Dublin   | Honda Civic  | 20              | Detail             |
+| Fremont  | Honda Accord | 15              | Detail             |
+| Fremont  | Honda CRV    | 7               | Detail             |
+| Fremont  | Honda Civic  | 10              | Detail             |
+| San Jose | Honda Accord | 8               | Detail             |
+| San Jose | Honda Civic  | 5               | Detail             |
+| Dublin   | NULL         | 33              | City Subtotal      |
+| Fremont  | NULL         | 32              | City Subtotal      |
+| San Jose | NULL         | 13              | City Subtotal      |
+| NULL     | Honda Accord | 33              | Model Subtotal     |
+| NULL     | Honda CRV    | 10              | Model Subtotal     |
+| NULL     | Honda Civic  | 35              | Model Subtotal     |
+| NULL     | NULL         | 78              | Total              |
+
+此查询清晰地标识了每行数据所属的聚合层级。
+
+***
+
+### 5.4 ROLLUP vs CUBE
+
+| 维度              | ROLLUP         | CUBE                |
+| --------------- | -------------- | ------------------- |
+| **生成分组集**       | 层级子集（从左到右）     | 所有可能组合              |
+| **ROLLUP(a,b**) | (a,b), (a), () | (a,b), (a), (b), () |
+| **分组数量**        | n+1（n为列数）      | 2ⁿ                  |
+| **使用场景**        | 层级报表、自上而下分析    | 多维交叉分析、BI 透视表       |
+| **性能**          | 生成分组数少，性能更优    | 生成分组数多，性能开销较大       |
+
+**选择建议**：
+
+* 需要**层级汇总**（如 地区→城市→门店）时使用 `ROLLUP`
+* 需要**多维交叉分析**（如 地区×产品×时间）时使用 `CUBE`
+* 需要**自定义组合**时使用 `GROUPING SETS`
+
+***
+
+## 六、HAVING 子句：过滤聚合结果
+
+### 6.1 WHERE vs HAVING
+
+| 子句         | 执行时机 | 作用对象  | 可用函数            |
+| ---------- | ---- | ----- | --------------- |
+| **WHERE**  | 分组前  | 原始行数据 | 标量函数、列比较        |
+| **HAVING** | 分组后  | 聚合结果  | 聚合函数、GROUP BY 列 |
+
+**执行顺序**：FROM → WHERE → GROUP BY → HAVING → SELECT → ORDER BY → LIMIT
+
+***
+
+### 6.2 使用 HAVING 过滤聚合结果
+
+筛选总销量超过 15 辆的城市：
+
+```sql
+SELECT 
+    city,
+    COUNT(*) AS record_count,
+    SUM(quantity) AS total_quantity
+FROM dealer
+GROUP BY city
+HAVING SUM(quantity) > 15
+ORDER BY total_quantity DESC
+LIMIT 50;
+```
+
+**查询结果**：
+
+| city    | record\_count | total\_quantity |
+| ------- | ------------- | --------------- |
+| Dublin  | 3             | 33              |
+| Fremont | 3             | 32              |
+
+San Jose（总销量 13 辆）被过滤掉，因为不满足 `HAVING` 条件。
+
+***
+
+### 6.3 WHERE 与 HAVING 组合
+
+先用 `WHERE` 过滤原始数据，再用 `HAVING` 过滤聚合结果：
+
+```sql
+SELECT 
+    city,
+    COUNT(*) AS record_count,
+    SUM(quantity) AS total_quantity
+FROM dealer
+WHERE quantity >= 10  -- 先过滤：只统计销量≥10的记录
+GROUP BY city
+HAVING COUNT(*) >= 2  -- 再过滤：只显示记录数≥2的城市
+ORDER BY total_quantity DESC
+LIMIT 50;
+```
+
+**执行逻辑**：
+
+1. **WHERE 过滤**：排除 quantity < 10 的记录（过滤掉 4 条记录）
+2. **GROUP BY 分组**：对剩余记录按 city 分组
+3. **HAVING 过滤**：只保留记录数 ≥ 2 的分组
+
+***
+
+## 七、高级应用场景
+
+### 7.1 行转列：透视分析
+
+将车型从行转换为列，实现透视表效果：
+
+```sql
+SELECT 
+    city,
+    SUM(CASE WHEN car_model = 'Honda Civic' THEN quantity ELSE 0 END) AS civic_sales,
+    SUM(CASE WHEN car_model = 'Honda Accord' THEN quantity ELSE 0 END) AS accord_sales,
+    SUM(CASE WHEN car_model = 'Honda CRV' THEN quantity ELSE 0 END) AS crv_sales,
+    SUM(quantity) AS total_sales
+FROM dealer
+GROUP BY city
+ORDER BY total_sales DESC
+LIMIT 50;
+```
+
+**查询结果**：
+
+| city     | civic\_sales | accord\_sales | crv\_sales | total\_sales |
+| -------- | ------------ | ------------- | ---------- | ------------ |
+| Dublin   | 20           | 10            | 3          | 33           |
+| Fremont  | 10           | 15            | 7          | 32           |
+| San Jose | 5            | 8             | 0          | 13           |
+
+**业务价值**：
+
+* 清晰展示每个城市各车型的销量分布
+* San Jose 没有 CRV 销售记录（显示为 0）
+* 适合用于 Excel 报表、BI 仪表板
+
+***
+
+### 7.2 占比分析：窗口函数与 GROUP BY
+
+计算每个车型在其所在城市的销量占比：
+
+```sql
+SELECT 
+    city,
+    car_model,
+    quantity,
+    SUM(quantity) OVER (PARTITION BY city) AS city_total,
+    ROUND(quantity * 100.0 / SUM(quantity) OVER (PARTITION BY city), 2) AS percentage
+FROM dealer
+ORDER BY city, car_model
+LIMIT 50;
+```
+
+**查询结果**：
+
+| city     | car\_model   | quantity | city\_total | percentage |
+| -------- | ------------ | -------- | ----------- | ---------- |
+| Dublin   | Honda Accord | 10       | 33          | 30.30      |
+| Dublin   | Honda CRV    | 3        | 33          | 9.09       |
+| Dublin   | Honda Civic  | 20       | 33          | 60.61      |
+| Fremont  | Honda Accord | 15       | 32          | 46.88      |
+| Fremont  | Honda CRV    | 7        | 32          | 21.88      |
+| Fremont  | Honda Civic  | 10       | 32          | 31.25      |
+| San Jose | Honda Accord | 8        | 13          | 61.54      |
+| San Jose | Honda Civic  | 5        | 13          | 38.46      |
+
+**业务洞察**：
+
+* **Dublin**：Honda Civic 占比 60.61%，是绝对主力车型
+* **Fremont**：销量分布较均衡，Accord 占比最高（46.88%）
+* **San Jose**：Accord 占比 61.54%，市场偏好明显
+
+**技术说明**：窗口函数 `SUM() OVER (PARTITION BY city)` 计算每个城市的总销量，但不改变行数。
+
+***
+
+### 7.3 同比环比分析模式
+
+虽然示例数据不包含时间维度，但提供标准的同比/环比分析 SQL 模式：
+
+```sql
+-- 示例：按月统计销量，计算环比增长
+SELECT 
+    DATE_FORMAT(sale_date, 'yyyy-MM') AS month,
+    SUM(quantity) AS monthly_sales,
+    LAG(SUM(quantity)) OVER (ORDER BY DATE_FORMAT(sale_date, 'yyyy-MM')) AS prev_month_sales,
+    ROUND(
+        (SUM(quantity) - LAG(SUM(quantity)) OVER (ORDER BY DATE_FORMAT(sale_date, 'yyyy-MM'))) * 100.0 / 
+        LAG(SUM(quantity)) OVER (ORDER BY DATE_FORMAT(sale_date, 'yyyy-MM')), 
+        2
+    ) AS mom_growth_rate
+FROM sales_table
+GROUP BY DATE_FORMAT(sale_date, 'yyyy-MM')
+ORDER BY month;
+```
+
+**关键技术**：
+
+* `LAG()` 窗口函数获取上一行的值
+* 环比增长率 = (当前值 - 上期值) / 上期值 × 100%
+
+***
+
+### 7.4 TopN 分析：每组取前 N
+
+使用窗口函数结合 GROUP BY 实现分组 TopN：
+
+```sql
+-- 示例：每个城市销量前 2 的车型
+SELECT *
+FROM (
+    SELECT 
+        city,
+        car_model,
+        quantity,
+        ROW_NUMBER() OVER (PARTITION BY city ORDER BY quantity DESC) AS rank
+    FROM dealer
+) ranked
+WHERE rank <= 2
+ORDER BY city, rank;
+```
+
+**预期逻辑**（基于当前数据）：
+
+* Dublin：Honda Civic (20), Honda Accord (10)
+* Fremont：Honda Accord (15), Honda Civic (10)
+* San Jose：Honda Accord (8), Honda Civic (5)
+
+***
+
+## 八、性能优化与最佳实践
+
+### 8.1 查询性能优化
+
+#### 1. 合理使用 LIMIT
+
+对于大数据集，始终添加 `LIMIT` 限制返回行数：
+
+```sql
+-- 推荐
+SELECT city, SUM(quantity) 
+FROM large_table 
+GROUP BY city
+LIMIT 100;
+
+-- 避免：可能返回数百万行
+SELECT city, SUM(quantity) 
+FROM large_table 
+GROUP BY city;
+```
+
+#### 2. 选择合适的聚合工具
+
+| 需求     | 推荐方案            | 生成分组数 | 性能    |
+| ------ | --------------- | ----- | ----- |
+| 简单层级汇总 | `ROLLUP`        | n+1   | ⭐⭐⭐⭐⭐ |
+| 多维交叉分析 | `CUBE`          | 2ⁿ    | ⭐⭐⭐   |
+| 自定义分组集 | `GROUPING SETS` | 自定义   | ⭐⭐⭐⭐  |
+
+**示例**：对于 3 列分组
+
+* `ROLLUP(a,b,c)` 生成 4 个分组集
+* `CUBE(a,b,c)` 生成 8 个分组集
+* `GROUPING SETS` 可自定义任意组合
+
+#### 3. 降低分组列基数
+
+对高基数列（如 ID、timestamp）使用函数降低粒度：
+
+```sql
+-- 避免：按秒级 timestamp 分组
+GROUP BY timestamp  -- 可能产生数百万个分组
+
+-- 推荐：按小时或天分组
+GROUP BY DATE_FORMAT(timestamp, 'yyyy-MM-dd')
+GROUP BY DATE_TRUNC('hour', timestamp)
+```
+
+#### 4. WHERE 过滤优于 HAVING 过滤
+
+尽量在 `WHERE` 中过滤数据，减少 `GROUP BY` 处理的数据量：
+
+```sql
+-- 推荐：先过滤再分组
+SELECT city, SUM(quantity)
+FROM dealer
+WHERE car_model = 'Honda Civic'  -- 先过滤，减少数据量
+GROUP BY city;
+
+-- 避免：先分组再过滤（处理了不必要的数据）
+SELECT city, car_model, SUM(quantity)
+FROM dealer
+GROUP BY city, car_model
+HAVING car_model = 'Honda Civic';
+```
+
+***
+
+### 8.2 常见错误与解决方案
+
+#### 错误 1：SELECT 列未在 GROUP BY 中
+
+```sql
+-- ❌ 错误示例
+SELECT city, car_model, quantity
+FROM dealer
+GROUP BY city;
+-- 错误：car_model 和 quantity 未分组或聚合
+
+-- ✅ 正确方案1：添加到 GROUP BY
+SELECT city, car_model, SUM(quantity)
+FROM dealer
+GROUP BY city, car_model;
+
+-- ✅ 正确方案2：使用聚合函数
+SELECT city, MAX(car_model), SUM(quantity)
+FROM dealer
+GROUP BY city;
+```
+
+#### 错误 2：WHERE 中使用聚合函数
+
+```sql
+-- ❌ 错误示例
+SELECT city, SUM(quantity)
+FROM dealer
+WHERE SUM(quantity) > 20  -- WHERE 不能使用聚合函数
+GROUP BY city;
+
+-- ✅ 正确方案：使用 HAVING
+SELECT city, SUM(quantity)
+FROM dealer
+GROUP BY city
+HAVING SUM(quantity) > 20;
+```
+
+#### 错误 3：混淆 ROLLUP/CUBE 语法
+
+```sql
+-- ❌ 错误示例
+GROUP BY city, ROLLUP(car_model)  -- 不支持混合语法
+
+-- ✅ 正确方案
+GROUP BY ROLLUP(city, car_model)
+```
+
+#### 错误 4：忽略 NULL 值影响
+
+```sql
+-- 在 ROLLUP/CUBE 中，NULL 既可能是真实 NULL，也可能是汇总标记
+-- 使用 GROUPING() 函数区分
+
+SELECT 
+    CASE WHEN GROUPING(city) = 1 THEN 'Total' ELSE city END AS city,
+    SUM(quantity)
+FROM dealer
+GROUP BY ROLLUP(city);
+```
+
+***
+
+### 8.3 数据质量检查
+
+#### 检查分组完整性
+
+验证分组汇总是否等于总计：
+
+```sql
+-- 方法1：使用 ROLLUP 自动生成总计行
+SELECT 
+    COALESCE(city, 'TOTAL') AS city,
+    SUM(quantity) AS total
+FROM dealer
+GROUP BY ROLLUP(city);
+
+-- 方法2：手动验证
+WITH group_totals AS (
+    SELECT SUM(quantity) AS grouped_sum
+    FROM dealer
+    GROUP BY city
+),
+grand_total AS (
+    SELECT SUM(quantity) AS total_sum
+    FROM dealer
+)
+SELECT 
+    (SELECT SUM(grouped_sum) FROM group_totals) AS sum_of_groups,
+    (SELECT total_sum FROM grand_total) AS grand_total,
+    CASE 
+        WHEN (SELECT SUM(grouped_sum) FROM group_totals) = (SELECT total_sum FROM grand_total)
+        THEN 'PASS'
+        ELSE 'FAIL'
+    END AS validation_result;
+```

+## 十、功能对比与选择指南
+
+### 10.1 四种分组方式对比
+
+| 特性        | GROUP BY | GROUPING SETS | ROLLUP | CUBE     |
+| --------- | -------- | ------------- | ------ | -------- |
+| **语法复杂度** | 简单       | 中等            | 简单     | 简单       |
+| **生成分组数** | 1        | 自定义           | n+1    | 2ⁿ       |
+| **灵活性**   | 低        | 高             | 中      | 中        |
+| **性能**    | 最优       | 优             | 优      | 较差（列数多时） |
+| **适用场景**  | 基础统计     | 自定义多维分析       | 层级报表   | 全维交叉分析   |
+
+***
+
+### 10.2 选择决策树
+
+```
+是否需要多维度汇总？
+├─ 否 → 使用标准 GROUP BY
+└─ 是 → 需要哪些维度组合？
+    ├─ 所有可能组合 → 使用 CUBE
+    ├─ 层级汇总（从细到总）→ 使用 ROLLUP
+    └─ 自定义特定组合 → 使用 GROUPING SETS
+```
+
+***
+
+### 10.3 推荐使用场景
+
+| 业务场景     | 推荐方案                 | 示例           |
+| -------- | -------------------- | ------------ |
+| 日常统计报表   | `GROUP BY`           | 按部门统计销售额     |
+| 财务分层汇总   | `ROLLUP`             | 公司→部门→团队层级汇总 |
+| BI 数据透视表 | `CUBE`               | 产品×地区×时间三维分析 |
+| 自定义业务报表  | `GROUPING SETS`      | 同时输出日报、周报、月报 |
+| 占比分析     | `GROUP BY` + 窗口函数    | 各产品销量占比      |
+| Top N 分析 | `GROUP BY` + `LIMIT` | 销量前10的产品     |
+
+***
+
+## 十一、进阶技巧
+
+### 11.1 动态分组
+
+使用变量或子查询实现动态分组条件（示例逻辑）：
+
+```sql
+-- 根据销量范围动态分组
+SELECT 
+    CASE 
+        WHEN SUM(quantity) >= 30 THEN 'High Volume'
+        WHEN SUM(quantity) >= 15 THEN 'Medium Volume'
+        ELSE 'Low Volume'
+    END AS volume_tier,
+    COUNT(DISTINCT city) AS city_count
+FROM (
+    SELECT city, SUM(quantity) AS city_total
+    FROM dealer
+    GROUP BY city
+) city_summary
+GROUP BY 
+    CASE 
+        WHEN city_total >= 30 THEN 'High Volume'
+        WHEN city_total >= 15 THEN 'Medium Volume'
+        ELSE 'Low Volume'
+    END;
+```
+
+***
+
+### 11.2 递归汇总（模拟）
+
+虽然云器 Lakehouse 目前还不直接支持递归 CTE，但可通过 UNION ALL 模拟多层级汇总：
+
+```sql
+-- 三层汇总：明细、城市小计、总计
+SELECT city, car_model, quantity, 'Detail' AS level
+FROM dealer
+UNION ALL
+SELECT city, NULL, SUM(quantity), 'City Subtotal'
+FROM dealer
+GROUP BY city
+UNION ALL
+SELECT NULL, NULL, SUM(quantity), 'Grand Total'
+FROM dealer
+ORDER BY 
+    CASE level 
+        WHEN 'Detail' THEN 1
+        WHEN 'City Subtotal' THEN 2
+        WHEN 'Grand Total' THEN 3
+    END,
+    city,
+    car_model;
+```
+
+***
+
+### 11.3 NULL 值处理技巧
+
+#### 技巧 1：区分真实 NULL 和聚合 NULL
+
+```sql
+SELECT 
+    city,
+    car_model,
+    SUM(quantity) AS total,
+    CASE 
+        WHEN GROUPING(city) = 1 THEN '[Subtotal]'
+        WHEN city IS NULL THEN '[Real NULL]'
+        ELSE city
+    END AS city_display
+FROM dealer
+GROUP BY ROLLUP(city, car_model);
+```
+
+#### 技巧 2：使用 COALESCE 美化输出
+
+```sql
+SELECT 
+    COALESCE(city, '📊 All Cities') AS city,
+    COALESCE(car_model, '🚗 All Models') AS car_model,
+    SUM(quantity) AS total
+FROM dealer
+GROUP BY CUBE(city, car_model);
+```
+
+***
+
+## 十二、总结
+
+### 核心要点
+
+1. **GROUP BY** 是数据聚合分析的基础，掌握其用法是 SQL 分析的必备技能
+2. **GROUPING SETS / ROLLUP / CUBE** 提供了强大的多维分析能力，一次查询生成多层级汇总
+3. **HAVING** 用于过滤聚合结果，与 WHERE 配合实现灵活的数据筛选
+4. **窗口函数** 与 GROUP BY 结合，可实现复杂的占比、排名、同环比分析
+5. **性能优化** 需要权衡灵活性与效率，合理选择分组方式
+
+***
+
+### 学习路径建议
+
+1. **基础阶段**：掌握标准 GROUP BY 和常用聚合函数
+2. **进阶阶段**：学习 GROUPING SETS、ROLLUP、CUBE 的使用场景
+3. **高级阶段**：结合窗口函数、CTE 实现复杂业务分析
+4. **实战阶段**：应用于实际业务场景，优化查询性能
+
+***
+
+### 快速参考
+
+```sql
+-- 基础分组
+SELECT column, AGG_FUNC(column) FROM table GROUP BY column;
+
+-- 多维分组
+SELECT col1, col2, AGG_FUNC(col3) 
+FROM table 
+GROUP BY GROUPING SETS ((col1, col2), (col1), ());
+
+-- 层级汇总
+SELECT col1, col2, AGG_FUNC(col3) 
+FROM table 
+GROUP BY ROLLUP(col1, col2);
+
+-- 交叉分析
+SELECT col1, col2, AGG_FUNC(col3) 
+FROM table 
+GROUP BY col1, col2 WITH CUBE;
+
+-- 条件过滤
+SELECT col1, AGG_FUNC(col2) 
+FROM table 
+WHERE condition
+GROUP BY col1 
+HAVING AGG_FUNC(col2) > value;
+```

+## IFNULL 函数
+
+IFNULL 函数是一个逻辑函数，用于处理 SQL 查询中可能出现的 NULL 值。当第一个参数的值为 NULL 时，IFNULL 函数返回第二个参数的值；如果第一个参数的值不为 NULL，则返回第一个参数的值。
+
+### 语法
+
+```sql
+IFNULL(expression_1, expression_2)
+```
+
+- `expression_1`：需要检查的表达式，通常是一个字段名。
+- `expression_2`：当 `expression_1` 为 NULL 时，要返回的值。
+
+### 使用说明
+
+- `expression_1` 和 `expression_2` 的数据类型必须相同或兼容。
+- 如果 `expression_1` 和 `expression_2` 的数据类型不兼容，IFNULL 函数将返回 NULL。
+- IFNULL 函数的返回值是 `expression_1` 或 `expression_2` 的数据类型。
+
+### 示例
+
+假设有一个名为 `student` 的表，包含以下列：
+
+- `id`：学生的唯一标识。
+- `name`：学生的姓名。
+- `score`：学生的成绩。
+
+表 `student` 的数据如下：
+
+| id | name  | score |
+|----|-------|-------|
+| 1  | Alice | 90    |
+| 2  | Bob   | NULL  |
+| 3  | Cathy | 80    |
+| 4  | David | NULL  |
+
+现在，我们想要查询每个学生的姓名和成绩，将成绩为 NULL 的记录替换为 0。可以使用以下 SQL 语句：
+
+```sql
+SELECT name, IFNULL(score, 0) AS score FROM student;
+```
+
+查询结果如下：
+
+| name  | score |
+|-------|-------|
+| Alice | 90    |
+| Bob   | 0     |
+| Cathy | 80    |
+| David | 0     |
+
+### 更多示例
+
+1. 查询学生的姓名和年龄，如果年龄为 NULL，则显示为 "Unknown"：
+
+```sql
+SELECT name, IFNULL(age, 'Unknown') AS age FROM student;
+```
+
+2. 查询员工的姓名和工资，如果工资为 NULL，则显示为 "Not available"：
+
+```sql
+SELECT name, IFNULL(salary, 'Not available') AS salary FROM employee;
+```
+
+3. 查询产品的名称和库存数量，如果库存数量为 NULL，则显示为 "Out of stock"：
+
+```sql
+SELECT product_name, IFNULL(stock_quantity, 'Out of stock') AS stock FROM products;
+```
+
+通过使用 IFNULL 函数，我们可以确保查询结果中不会出现 NULL 值，从而提高数据的可读性和可用性。

+# ilike运算符使用指南
+
+ilike运算符是SQL语句中用于判断字符串匹配模式的一种工具，它能够忽略大小写的差异，从而更加灵活方便地进行字符串匹配。与传统的like运算符相比，ilike运算符在处理大小写不一致的情况时更为方便。
+
+## 语法
+
+ilike运算符的基本语法如下：
+
+```SQL
+str [ NOT ] ilike pattern [ escape escape_char ]
+str [ NOT ] ilike { ANY | SOME | ALL } ( [ pattern [, ...] ] ) [ escape escape_char ]
+```
+
+在这里，`str`代表要匹配的字符串表达式，`pattern`代表要匹配的模式表达式，`escape escape_char`是用于转义特殊字符的单字符字符串字面量。`ANY`、`SOME`和`ALL`用于指定多个模式之间的逻辑关系。当使用`ALL`时，表示`str`必须匹配所有模式；而使用`ANY`或`SOME`时，表示`str`只需匹配至少一个模式。
+
+### ilike的模式
+
+ilike的模式中可以包含以下特殊字符：
+
+- `_`：匹配任意单个字符（类似于POSIX正则表达式中的`.`）。
+- `%`：匹配任意个数的字符（类似于POSIX正则表达式中的`.*`）。
+
+## 使用示例
+
+假设有一个名为students的表，它包含学生的姓名和班级信息，如下所示：
+
+```SQL
+CREATE TABLE students (
+  name STRING,
+  class STRING
+);
+
+INSERT INTO students (name, class) VALUES
+('Alice', 'A'),
+('Bob', 'B'),
+('Carol', 'A'),
+('David', 'C');
+```
+
+以下是使用ilike运算符的查询示例：
+
+1.  查询姓名中包含“a”（不区分大小写）的学生：
+
+```SQL
+SELECT name, class
+FROM students
+WHERE name ILIKE '%a%';
+
++-------+-------+
+| name  | class |
++-------+-------+
+| Alice | A     |
+| Carol | A     |
+| David | C     |
++-------+-------+
+```
+
+2.  查询姓名以“a”或“b”开头的学生（不区分大小写）：
+
+```SQL
+SELECT name, class
+FROM students
+WHERE name ILIKE ANY ('a%', 'b%');
+
++-------+-------+
+| name  | class |
++-------+-------+
+| Alice | A     |
+| Bob   | B     |
++-------+-------+
+```
+
+3.  查询姓名中同时包含“a”和“l”的学生（不区分大小写）：
+
+```SQL
+SELECT name, class
+FROM students
+WHERE name ILIKE ALL ('%a%', '%l%');
+
++-------+-------+
+| name  | class |
++-------+-------+
+| Alice | A     |
+| Carol | A     |
++-------+-------+
+```
+
+## 注意事项
+- 当使用ilike运算符时，如果模式中包含特殊字符，建议使用`escape`子句来转义这些特殊字符，以避免歧义。

+# 数据导入Lakehouse操作实践\_通过Python脚本
+
+在现代数据处理中，将数据导入数据库是一个常见的需求。使用 Python 脚本实现数据导入可以带来许多优势，适用于多种场景，例如自动化、数据处理、支持多种数据库等。本文将以 PostgreSQL 数据库为例，演示如何将数据导入云器 Lakehouse。
+
+## 优势介绍
+
+1. **自动化**：通过创建定期或按需运行的自动化任务，可以实现数据的实时更新或迁移。
+
+2. **数据处理**：Python 具有强大的数据处理功能，可以在将数据导入数据库之前对其进行预处理、清洗和转换，以提高数据质量与导入成功率。
+
+3. **支持多种数据库**：Python 提供了广泛的数据库驱动程序和库，支持关系型数据库（如 MySQL、PostgreSQL、SQLite 等）和非关系型数据库（如 MongoDB、Redis 等）。
+
+4. **错误处理和日志记录**：使用 Python 编写导入脚本时，可以捕获异常并记录详细日志，从而更容易地跟踪和解决数据导入过程中的问题。
+
+## 适用场景举例
+
+1. 将 CSV 或 Excel 文件中的数据导入数据库。
+2. 在将数据导入数据库之前，对数据应用统计方法或规范化等方法进行预处理。
+3. 包含数据验证和完整性检查的数据库迁移任务。
+
+## 操作指南
+
+### 1. 导入需要的Python包
+
+```python
+from sqlalchemy import create_engine
+import pandas as pd
+import psycopg2
+import pygwalker as pyg
+```
+
+### 2. 创建连接到 PostgreSQL 数据库并读取源表数据
+
+```python
+def create_conn_pg(database: str, user: str, password: str, host: str, port: str):
+    connection = psycopg2.connect(
+        dbname=database,
+        user=user,
+        password=password,
+        host=host,
+        port=port
+    )
+    return connection
+```
+
+### 3. 使用 `pd.read_sql_query()` 方法从数据库中查询数据并存储到 DataFrame 中
+
+```python
+conn_pg = create_conn_pg("<database>", "<username>", "<password>", "<host>", "<port>")
+query = "SELECT * FROM public.orders;"
+df = pd.read_sql_query(query, conn_pg)
+conn_pg.close()
+```
+
+### 4. 查看 PostgreSQL 数据并进行清洗与可视化分析
+
+```python
+# 查看数据总行数
+print(df.shape[0])
+
+# 替换所有nan值为0
+df.fillna(0, inplace=True)
+
+# 显示前5行数据
+print(df.head(5))
+```
+
+### 5. 使用 PyGWalker 进行数据透视分析（可选）
+
+```python
+walker = pyg.walk(df)
+```
+
+### 6. 在 ClickZetta Lakehouse 中创建目标表
+
+```python
+engine_cz = create_engine("clickzetta://<username>:<password>@<instanceid>.<region_id>.api.clickzetta.com/<workspacename>?virtualcluster=<vcluster>&schema=<public>")
+sql_cz = text("""
+CREATE TABLE IF NOT EXISTS orders_tmp (
+    id INT,
+    user_id INT,
+    product_id INT,
+    subtotal DECIMAL(8, 2),
+    tax DECIMAL(8, 2),
+    total DECIMAL(16, 3),
+    discount DECIMAL(8, 2),
+    created_at TIMESTAMP,
+    quantity INT
+);
+""")
+with engine_cz.connect() as conn:
+    results = conn.execute(sql_cz)
+```
+
+### 7. 将转换后的源表数据写入云器 Lakehouse 目标表
+
+```python
+conn_cz = connect(
+    username="<username>",
+    password="<password>",
+    service="<region_id>.api.clickzetta.com",
+    instance="<instanceid>",
+    workspace="<workspacename>",
+    schema="public",
+    vcluster="default"
+)
+bulkload_stream = conn_cz.create_bulkload_stream(schema="public", table="orders")
+writer = bulkload_stream.open_writer(0)
+for index, row_data in df.iterrows():
+    row = writer.create_row()
+    row.set_value("id", row_data["id"])
+    row.set_value("created_at", row_data["created_at"])
+    row.set_value("user_id", row_data["user_id"])
+    row.set_value("product_id", row_data["product_id"])
+    row.set_value("subtotal", row_data["subtotal"])
+    row.set_value("tax", row_data["tax"])
+    row.set_value("total", row_data["total"])
+    row.set_value("discount", row_data["discount"])
+    row.set_value("quantity", row_data["quantity"])
+    writer.write(row)
+writer.close()
+bulkload_stream.commit()
+```
+
+### 8. 资源清理
+
+```
+#删除云器 Lakehouse目标表
+sql_cz = text("""drop table if exists orders ;""")
+with engine_cz.connect() as conn:
+    results = conn.execute(sql_cz)
+```

+# 介绍
+
+LAKEHOUSE 的 INFORMATION_SCHEMA 提供了项目实例（INSTANCE）及使用历史数据等详细信息，帮助您全面了解所有空间的信息。通过查询INFORMATION_SCHEMA，您可以查看所有空间的元数据信息和使用历史信息。INFORMATION_SCHEMA 基于 ANSI SQL-92 标准，同时增加了一些 LAKEHOUSE 服务特有的字段和视图。当您创建 LAKEHOUSE 实例时，系统会自动在名为 SYS 的系统空间中创建一个 INFORMATION_SCHEMA。INFORMATION_SCHEMA不仅记录了当前存在的元数据对象，还记录了已经删除的元数据对象。您可以通过DELETE_TIME字段来判断一个元数据对象是否被删除，以及删除的时间。如果DELETE_TIME字段为NULL，表示该元数据对象尚未被删除。需要注意的是，目前存在约 15 分钟的延迟。
+
+# 使用限制
+
+* 实例级别 SYS 下的视图，被删除对象保留 60 天记录。视图当前阶段存在约 15 分钟的延迟。JOB_HISTORY、MATERIALIZED_VIEW 刷新视图保留 60 天记录。
+* 每个INFORMATION_SCHEMA下的表和视图都是只读的（不能修改或删除）。
+* 对 INFORMATION_SCHEMA 视图的查询不保证与并发 DDL 操作的一致性。例如，在执行长时间运行的 INFORMATION_SCHEMA 查询时创建了一组表，则查询结果可能不包含这些新创建的表。
+
+# 访问SYS下的INFORMATION_SCHEMA
+
+要访问 SYS 下的 INFORMATION_SCHEMA，您需要具备 INSTANCE ADMIN 权限。以下是查询 INFORMATION_SCHEMA 的一个示例：
+
+```SQL
+SELECT * FROM SYS.information_schema.tables;
+```
+
+以下是一些查询INFORMATION_SCHEMA的示例，帮助您更好地了解如何使用这些视图和表。
+
+1. 查询所有空间的元数据信息：
+
+```SQL
+SELECT * FROM SYS.information_schema.columns;
+```
+
+2. 查询指定空间的表信息：
+
+```SQL
+SELECT * FROM SYS.information_schema.tables WHERE table_schema = 'your_schema_name';
+```
+
+3. 查询已删除的元数据对象：
+
+```SQL
+SELECT * FROM SYS.information_schema.columns WHERE delete_time IS NOT NULL;
+```
+
+4. 查询表的创建时间：
+
+```SQL
+SELECT table_name, create_time FROM SYS.information_schema.tables WHERE table_schema = 'your_schema_name';
+```
+
+5. 查询JOB HISTORY信息：
+
+```SQL
+SELECT * FROM SYS.information_schema.job_history;
+```
+
+通过以上示例，您可以更深入地了解如何使用 INFORMATION_SCHEMA 来查询和管理 LAKEHOUSE 实例中的元数据和使用历史信息。

+# 使用内部 Volume
+
+内部 Volume（Internal Volume）是系统提供的默认文件存储区域，用于临时存放待处理或待加载的数据文件。
+
+* 对于没有云存储的用户，可以直接上传文件到内部 Volume 作为数据文件的主要存储区域，系统提供完全托管的存储服务。
+* 而已使用云对象存储的用户，则可以选择使用外部 Volume（External Volume），通过直接挂载云存储路径进行访问，无需额外的数据迁移和复制。
+
+系统目前支持三种类型的内部 Volume：User Volume、Table Volume 和命名 Volume。
+
+### 使用User Volume
+
+User Volume 是用户专属的个人存储空间，类似于操作系统中用户的默认工作目录，在 Lakehouse 中这个目录不可删除。用户默认对 User Volume 具备读写权限。
+
+| **用户对 USER VOLUME 的操作** |
+| :------------------------- |
+| SHOW USER VOLUME DIRECTORY |
+| SELECT FROM VOLUME         |
+| PUT                        |

+```
+
+* 通过SQL查询User Volume下文件
+
+```SQL
+--通过SQL查询User Volume下指定文件
+SELECT * FROM USER VOLUME 
+USING CSV
+OPTIONS(
+        'header'='true'
+)
+FILES( 'taxi_zone_lookup.csv')
+LIMIT 5;

+
+
+--通过SQL查询User Volume指定路径下所有文件
+SELECT * FROM USER VOLUME using csv subdirectory '/tmp/';
+```
+
+* 使用 `get_presigned_url` 函数，获取 Volume 下文件在对象存储的待临时签名的真实访问路径。
+
+```SQL
+--获取presign url, 获取oss内网url
+SELECT get_presigned_url(USER VOLUME , 'images/image.png' , 60) as url;
+
+--获取presign url,获取对外url
+set cz.sql.function.get.presigned.url.force.external=true;
+SELECT get_presigned_url(USER VOLUME , 'images/image.png' , 60) as url;
+```
+
+### 使用Table Volume
+
+每个Lakehouse 表默认关联一个存储空间，我们称之为Table Volume。用户对指定表的 Table Volume 进行操作时需要具备以下权限：
+
+| **TABLE VOLUME 操作**                         | **对应 TABLE 权限需求**        |
+| :----------------------------------------- | :--------------------- |
+| SHOW TABLE VOLUME DIRECTORY \<table\_name> | SELECT                 |
+| SELECT FROM VOLUME \<table\_name>          | SELECT                 |
+| PUT                                        | INSERT,UPDATE,DELETE   |
+| GET                                        | SELECT                 |
+| LIST                                       | SCHEMA READ            |
+| REMOVE                                     | INSERT, UPDATE, DELETE |
+
+以下通过示例说明 Table Volume 的操作使用。
+
+```SQL
+--创建表
+CREATE TABLE t_copy_from_volume(id int, name string);
+
+--查看指定表的Table volume
+SHOW TABLE VOLUME DIRECTORY t_copy_from_volume;
+```
+
+上传文件至目标表的TABLE VOLUME，要求访问用户具有目标表的写入权限。
+
+```SQL
+--上传文件至table volume，不指定存储路径默认保存在根路径下
+PUT '/Users/Downloads/data.csv' TO TABLE VOLUME t_copy_from_volume FILE 'data.csv';
+
+source                           target   source_size target_size status  
+-------------------------------- -------- ----------- ----------- ------- 
+/Users/Downloads/data.csv data.csv 34          34          SUCCEED 
+```
+
+使用SQL探查上传至TABLE VOLUME下文件数据。
+
+```SQL
+--查询
+SELECT * FROM TABLE VOLUME t_copy_from_volume
+USING CSV
+OPTIONS(
+        'header'='true',
+        'lineSep'='\n'
+)
+
+id name  
+-- ----- 
+1  hello 
+2  world 
+3  !     
+```
+
+使用COPY INTO命令导入文件数据到目标表。
+
+```SQL
+COPY INTO t_copy_from_volume FROM TABLE VOLUME t_copy_from_volume(id int, name string)  USING csv  
+OPTIONS(
+        'header'='true',
+        'lineSep'='\n'
+)
+FILES ('data.csv')
+--删除volume中的文件，节省存储
+PURGE=TRUE;
+```
+
+查询目标表，验证导入结果。
+
+```SQL
+--查看导入结果
+SELECT * FROM t_copy_from_volume;
+
+id name  
+-- ----- 
+1  hello 
+2  world 
+3  !     
+```
+
+删除TABLE VOLUME下文件。
+
+```SQL
+--删除Table Volume下指定文件
+REMOVE TABLE VOLUME t_copy_from_volume  FILE 'data.csv'
+--删除Table Volume下指定路径下所有文件
+REMOVE TABLE VOLUME t_copy_from_volume subdirectory '/'
+```
+
+### 使用命名Volume
+
+命名 Volume 是用户显式创建的，创建后存储在 Lakehouse 管理的内部存储中，无需额外云存储配置。它提供了比自动生成的用户级（User Volume）和表级（Table Volume）更精细的控制能力。
+
+#### 语法说明
+
+##### 创建命名 Volume
+
+```SQL
+CREATE VOLUME [ IF NOT EXISTS ] <volume_name>
+    DIRECTORY = (
+        enable =  true,    
+        auto_refresh = true
+    )
+    RECURSIVE = true          -- 是否递归扫描子目录（默认false）
+```
+
+^
+
+#### 删除Volume
+
+```SQL
+DROP VOLUME [ IF EXISTS ] <volume_name>
+```
+
+#### 使用具体案例
+
+上传和下载数据
+
+```sql
+--创建volume
+CREATE  VOLUME my_volume
+    DIRECTORY = (
+        enable=true,
+        auto_refresh=true
+    )
+    RECURSIVE=true;
+SHOW VOLUME DIRECTORY my_volume;
+
+COPY INTO VOLUME my_volume  SUBDIRECTORY 'dau_unload/'
+FROM TABLE public.students01
+file_format = (
+    type= CSV
+    writebom=true
+);
+SHOW VOLUME DIRECTORY my_volume;
+--本地上传下载测试
+GET VOLUME my_volume FILE 'dau_unload/part00001.csv' TO '/tmp';
++---------------+--------------------+-------------+-------------+---------+
+|    source     |       target       | source_size | target_size | status  |
++---------------+--------------------+-------------+-------------+---------+
+| part00001.csv | /tmp/part00001.csv | 1472        | 1472        | SUCCEED |
++---------------+--------------------+-------------+-------------+---------+
+
+ PUT '/tmp/part00001.csv' to volume my_volume file 'my.csv';
++--------------------+--------+-------------+-------------+---------+
+|       source       | target | source_size | target_size | status  |
++--------------------+--------+-------------+-------------+---------+
+| /tmp/part00001.csv | my.csv | 1472        | 1472        | SUCCEED |
++--------------------+--------+-------------+-------------+---------+
+
+```
+
+## 数据操作协议
+
+| 协议类型         | 地址格式                             | 典型场景     |

+# 倒排索引
+
+## 概述
+
+### 倒排索引原理介绍
+
+1. 基本概念
+   倒排索引由两部分组成：
+   * **词典（Dictionary）**：存储所有文档集合中出现过的唯一单词（或短语）的列表。
+   * **倒排表（Posting List）**：对于词典中的每个单词，都有一个与之对应的倒排列表，记录了包含这个单词的所有文档的文档ID以及单词在文档中出现的位置信息。
+
+2. 构建过程
+   * **分词（Tokenization）**：将文档内容分割成单词或短语的过程。
+   * **标准化（Normalization）**：对分词结果进行处理，如转小写、去除停用词、词干提取等。
+   * **构建词典**：将处理后的单词加入词典，并为每个单词分配一个唯一的ID。
+   * **构建倒排列表**：对于每个文档，记录下文档中所有单词的ID和位置信息，并将这些信息与词典中的单词ID关联起来，形成倒排列表。
+
+3. 查询过程
+   当用户提交一个查询请求时，搜索引擎会执行以下步骤：
+   * **查询解析**：将用户的查询语句分解成单词或短语。
+   * **查找词典**：在词典中查找这些单词或短语的ID。
+   * **检索倒排列表**：根据单词ID，从倒排列表中检索包含这些单词的所有文档ID。
+   * **合并结果**：根据查询语句中的逻辑（如AND、OR、NOT等），合并不同单词的检索结果，确定最终的文档列表。
+
+4. 应用场景
+   倒排索引主要用于全文搜索领域，如搜索引擎、文档检索系统等，它能够快速响应用户的查询请求，提供高效的检索服务。
+
+### 功能介绍
+
+利用倒排索引可以根据关键词快速定位包含它的行，达到查询加速的目的。同时，如上文原理介绍，词典和倒排列表会产生额外的 Lakehouse 存储。
+
+1. 全文检索能力
+   支持字符串类型的全文检索，支持`match_all`、`match_any`、`match_phrase`、`match_phrase_prefix`、`match_regexp`函数。Lakehouse 在部分场景下`like`也会使用倒排索引，但仍推荐您使用全文检索函数。
+
+2. 查询加速
+   * 支持字符串、数值类型的 =、!=、>、>=、<, <=
+BUILD INDEX index_name ON table_name WHERE partition_name1 = '1' and partition_name2 = '2';
+```
+
+* index\_name：指定要添加倒排索引名称
+* 支持指定分区构建：可以指定一个或者多个
+
+#### 说明
+
+执行BUILD INDEX是一个同步任务，执行过程会消耗计算资源。查看进度可以通过Job Profile查看。
+
+当分区表数据量较大时，建议以分区为粒度依次创建索引。
+
+#### 案例
+
+```SQL
+BUILD INDEX bulkload_data_index ON public.bulkload_data ;
+```
+
+### 列出表上所有的倒排索引
+
+命令用于列出指定表中已创建的倒排索引。
+
+#### 语法
+
+```SQL
+SHOW INDEX FROM [schema].table_name;
+```
+
+#### 案例
+
+```SQL
+ show index from public.bulkload_data;
++---------------------+------------+
+|     index_name      | index_type |
++---------------------+------------+
+| bulkload_data_index | inverted   |
++---------------------+------------+
+```
+
+### 查看倒排索引详情
+
+本命令用于列出指定表中已创建的倒排索引的详情，添加上extended关键字可以查看倒排索引大小。
+
+#### 语法
+
+```SQL
+DESC INDEX [EXTENDED]  index_name;
+```
+
+#### 案例
+
+```SQL
+desc index bulkload_data_index;
++--------------------+-------------------------+
+|     info_name      |       info_value        |
++--------------------+-------------------------+

+| properties               | (("analyzer","unicode")) |
+| index_type               | inverted                 |
+| table_name               | bulkload_data            |
+| table_column             | data                     |

+| index_size_in_index_file | 0                        |
+| total_index_size         | 0                        |
++--------------------------+--------------------------+
+```
+
+### 删除倒排索引
+
+#### 语法
+
+```SQL
+DROP INDEX [IF EXISTS] index_name;
+```
+
+参数说明：
+
+* `DROP INDEX`：删除索引的关键字。
+* `IF EXISTS`：可选参数，如果指定的索引不存在，则不报错。
+* `index_name`：要删除的索引名称。
+
+#### 说明
+
+执行drop index会立即成功，会删除掉index的元数据信息。但是不会立即删除索引存储信息。
+
+## 分析器高级配置
+
+在创建倒排索引时，除了指定分析器类型（`analyzer`），还可以通过 `PROPERTIES` 配置停用词（stopwords）和词干提取（stemmer），进一步控制分词行为。
+
+### 停用词（Stopwords）
+
+停用词是指在全文检索中通常不携带实质意义、需要过滤掉的常见词汇（如英文中的 "the"、"is"、"a" 等）。过滤停用词可以减小索引体积、提升检索精度。
+
+支持两种配置方式：
+
+| 属性 | 说明 |
+|------|------|
+| `stopwords` | 使用内置停用词表，目前支持 `english` |
+| `custom_stopwords` | 自定义停用词，多个词用英文逗号分隔，优先级高于 `stopwords` |
+
+**默认行为**：不配置时停用词过滤默认关闭，所有词均会被索引。
+
+**示例：使用内置英文停用词**
+
+```SQL
+CREATE TABLE articles(
+   id INT,
+   content STRING,
+   INDEX content_index (content) INVERTED PROPERTIES('analyzer'='english', 'stopwords'='english')
+);
+```
+
+分词效果：`"The quick brown fox"` → `["quick", "brown", "fox"]`（"the" 被过滤）
+
+**示例：使用自定义停用词**
+
+```SQL
+CREATE TABLE articles(
+   id INT,
+   content STRING,
+   INDEX content_index (content) INVERTED PROPERTIES('analyzer'='english', 'custom_stopwords'='hello,world,test')
+);
+```
+
+分词效果：`"hello world this is a test"` → `["this", "is", "a"]`
+
+> **注意**：`custom_stopwords` 与 `stopwords` 同时配置时，`custom_stopwords` 优先生效，内置停用词表不会被使用。
+
+**内置英文停用词列表**
+
+内置英文停用词基于 Lucene/Elasticsearch 标准停用词表，包含：`a`、`an`、`and`、`are`、`as`、`at`、`be`、`but`、`by`、`for`、`if`、`in`、`into`、`is`、`it`、`no`、`not`、`of`、`on`、`or`、`such`、`that`、`the`、`their`、`then`、`there`、`these`、`they`、`this`、`to`、`was`、`will`、`with`。
+
+### 词干提取（Stemmer）
+
+词干提取将单词还原为词根形式，使不同形态的同一词汇能够匹配（如 `running`、`runs`、`ran` 均还原为 `run`）。底层使用 [Snowball](https://snowballstem.org/) 算法库。
+
+配置方式：
+
+| 属性 | 说明 |
+|------|------|
+| `stemmer` | 指定 Snowball 算法，格式为 `snowball_<language>`，如 `snowball_english`、`snowball_german`、`snowball_french` 等 |
+
+**示例：英文词干提取**
+
+```SQL
+CREATE TABLE articles(
+   id INT,
+   content STRING,
+   INDEX content_index (content) INVERTED PROPERTIES('analyzer'='english', 'stemmer'='snowball_english')
+);
+```
+
+分词效果：`"running quickly"` → `["run", "quick"]`
+
+**示例：词干提取 + 停用词组合使用**
+
+```SQL
+CREATE TABLE articles(
+   id INT,
+   content STRING,
+   INDEX content_index (content) INVERTED PROPERTIES(
+     'analyzer'='english',
+     'stemmer'='snowball_english',
+     'stopwords'='english'
+   )
+);
+```
+
+分词效果：`"The dogs are running"` → `["dog", "run"]`（"the"、"are" 被停用词过滤，"dogs" 和 "running" 经词干提取还原）
+
+> **注意**：词干提取在停用词过滤之前执行，处理顺序为：分词器 → 词干提取 → 停用词过滤。
+
+**在查询函数中使用**
+
+查询时同样可以通过 `option` 参数指定停用词和词干提取，确保查询分词与索引分词一致：
+
+```SQL
+-- 使用停用词
+SELECT tokenize('The quick brown fox', map('analyzer', 'english', 'stopwords', 'english'));
+-- 返回: ["quick", "brown", "fox"]
+
+-- 使用词干提取
+SELECT tokenize('running quickly', map('analyzer', 'english', 'stemmer', 'snowball_english'));
+-- 返回: ["run", "quick"]
+
+-- 组合使用
+SELECT match_all(content, 'dogs running', map('analyzer', 'english', 'stemmer', 'snowball_english', 'stopwords', 'english'))
+FROM articles;
+```
+
+## 使用倒排索引查询
+
+### 倒排索引函数
+
+函数中要求分词和表保持一致，否则无法使用倒排索引加速查询。不指定option参数时会自动映射字段已有索引中的分词。
+
+#### tokenize
+
+**语法：**
+
+```SQL
+tokenize(input[, option])
+```
+
+**功能：** 分词，返回值为array
+
+**示例：**
+
+```SQL
+SELECT tokenize('a b', map('analyzer', 'english'));
+-- 返回: ["a", "b"]
+```
+
+#### match_all
+
+**语法：**
+
+```SQL
+match_all(input, query[, option])
+```
+
+**功能：** 匹配所有，先将query分词，再将input分词，需要保证input的分词结果包含所有query分词结果，返回bool
+
+**示例：**
+
+```SQL
+SELECT match_all('a b c', 'b a', map('analyzer', 'english'));
+-- 返回: true
+```
+
+#### match_any
+
+**语法：**
+
+```SQL
+match_any(input, query[, option])
+```
+
+**功能：** 匹配任意，input的分词结果包含query分词结果的任意元素即可，返回bool
+
+**示例：**
+
+```SQL

+--使用倒排索引加速id列的等值查询
+SELECT id, data FROM bulkload_data WHERE id = 3;
++----+------------------------------------------+
+| id |                   data                   |
++----+------------------------------------------+
+| 3  | Lakehouse supports multiple data types   |
++----+------------------------------------------+
+
+--使用倒排索引加速id列的范围查询
+SELECT id, data FROM bulkload_data WHERE id >
+
+## 使用注意事项
+
+### 倒排索引无法优化场景
+
+* 在大多数情况下，倒排索引并不会显著提升亚秒级查询的性能。
+* 不支持外部表。
+* 仅支持数据类型一致的查询，例如：
+
+```SQL
+--可以查询加速的，表中数据类型string
+where string_col='10086';
+--对需要匹配的值进行转化
+where string_col=cast(10086 as string);
+
+--无法查询加速的，因为对表列进行了强制转化
+where cast(string_col as int)=10086 ;
+```
+
+## 计费说明
+
+* 存储资源：倒排索引会在数据文件之外额外创建倒排索引文件，索引文件和数据文件将按照存储大小统一计收存储费用。

+# Lakehouse 倒排索引 BM25 参数调优
+
+BM25（Best Matching 25）是现代全文检索中最重要的相关性评分算法之一。Lakehouse 的倒排索引支持 BM25 算法，并允许用户调整关键参数以优化不同场景下的搜索效果。
+
+支持参数：
+
+`k1`  - 词频饱和度控制
+
+* **取值范围**:` [0.0, 3.0]`，推荐范围 `[1.0, 2.0]`
+
+* **默认值**: `1.2`
+
+* **作用**: 控制词频对相关性评分的影响程度
+
+* **效果**:
+
+  * **k1 越大**: 词频对评分的影响越大，高频词文档更容易获得高评分
+* **k1 越小**: 词频饱和更快，减少高频词的过度影响
+
+`b`  - 文档长度归一化
+
+* **取值范围**:` [0.0, 1.0]`
+
+* **默认值**: `0.75`
+
+* **作用**: 控制文档长度对相关性评分的影响程度
+
+* **效果**:
+
+  * **b = 0**: 完全忽略文档长度，长短文档同等对待
+  * **b = 1**: 完全长度归一化，短文档获得显著优势
+  * **b = 0.75**: 平衡长度影响，适合大多数场景
+
+在 Lakehouse 中，通过在 SQL 语句之前添加以下语句：
+
+```
+SET cz.storage.parquet.inverted.index.similarity.bm25={"k1": 1.2, "b": 0.75} 
+```
+
+实现对搜索效果的控制。
+

+# 倒排索引 multi-match 功能
+
+`multi-match` 是一种强大的查询功能，它允许用户将一个**单一的查询字符串**同时在**多个字段**上进行搜索。这在许多实际应用场景中都非常有用，例如，当一个电商网站的用户在搜索框输入 "durable backpack" 时，系统可能需要同时在 `product_title` (产品标题)、`description` (描述) 和 `category` (分类) 等多个字段中查找。
+
+当执行一个 multi-match 查询时，系统会在后台为指定的每一个字段执行匹配操作，然后将所有结果进行智能合并和排序，最终返回一个统一的相关度排序列表。
+
+^
+
+## 功能示例
+
+### 数据准备：
+
+测试数据表：
+
+```

+```
+
+表结构：
+
+* `id` (string) - 实体ID
+* `title` (string) - 实体标题
+* `text` (string) - 实体描述文本
+* `vec` (vector(float,1536)) - 1536维向量

+
+#### 多字段联合搜索
+
+**三字段联合搜索 (ID + Title + Text)**

+`IS NULL` 子句用于在 `WHERE` 条件中判断列中的值是否为 `NULL`。`NULL` 表示该列没有值，或者值未知。需要注意的是，`NULL` 与空字符串或空格不同，后者是有具体值的。
+
+## 注意事项
+
+使用等号（`=`）来判断 `NULL` 是无法得到预期结果的，因为 `NULL` 不能用等号来比较。
+
+## 语法
+
+```sql
+SELECT * FROM table_name WHERE expression IS NULL;
+SELECT * FROM table_name WHERE expression IS NOT NULL;
+```
+
+其中，`expression` 是要判断的表达式，它可以是任意类型。`IS NULL` 和 `IS NOT NULL` 的返回值是布尔类型（`BOOLEAN`），如果 `expression` 的值为 `NULL`，则返回 `TRUE`，否则返回 `FALSE`。
+
+## 示例
+
+假设我们有一个名为 `student` 的表，其中包含以下数据：
+
+| id | name  | gender |
+|----|-------|--------|
+| 1  | Alice | F      |
+| 2  | Bob   | M      |
+| 3  | Cathy | F      |
+| 4  | David | NULL   |
+
+1. 现在，我们想要从 `student` 表中查询性别为 `NULL` 的学生，我们可以使用以下 SQL 语句：
+
+   ```sql
+   SELECT * FROM student WHERE gender IS NULL;
+   ```
+
+   结果集如下：
+
+   | id | name  | gender |
+   |---|-------|--------|
+   | 4  | David | NULL   |
+
+2. 如果我们想要查询性别不为 `NULL` 的学生，我们可以使用以下 SQL 语句：
+
+   ```sql
+   SELECT * FROM student WHERE gender IS NOT NULL;
+   ```
+
+   结果集如下：
+
+   | id | name  | gender |
+   |---|-------|--------|
+   | 1  | Alice | F      |
+   | 2  | Bob   | M      |
+   | 3  | Cathy | F      |
+
+## 常见问题
+
+Q: 为什么使用等号（`=`）判断 `NULL` 值无法得到预期结果？
+
+A: 这是因为 `NULL` 表示未知或缺失的值，所以它不能与任何值（包括 `NULL`）进行比较。使用等号（`=`）判断 `NULL` 值时，结果会是 `UNKNOWN`，而不是 `TRUE` 或 `FALSE`。因此，我们需要使用 `IS NULL` 或 `IS NOT NULL` 来判断 `NULL` 值。

+# 客户端
+
+本文档介绍了 ClickZettaClient 的初始化和使用方法。ClickZettaClient 是用于连接 Lakehouse 的客户端，可用于创建 RowStream 和 JDBC 连接。
+
+## ClickZettaClient初始化
+
+ClickZettaClient支持通过JDBC URL或参数形式进行连接。以下是两种初始化方式的示例：
+
+### 通过JDBC URL连接客户端
+
+```java
+ClickZettaClient client = ClickZettaClient.newBuilder()
+    .url("jdbc:clickzetta://instanceName.service/{0}?schema={1}&username={2}&password={3}&virtualcluster={4}")
+    .build();
+```
+
+### 通过参数形式连接客户端
+
+```java
+ClickZettaClient client = ClickZettaClient.newBuilder()
+    .instance("instanceName")
+    .service("service")
+    .workspace("worksapceName")
+    .username("username")
+    .password("password")
+    .vcluster("cluster")
+    .schema("schema")
+    .build();
+```
+
+| **参数**    | **是否必填** | **描述**                                                                                                                              |
+| --------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------- |
+| username  | Y        | 用户名                                                                                                                                 |
+| password  | Y        | 密码                                                                                                                                  |
+| service   | Y        | 连接lakehouse的地址, region\_id.api.clickzetta.com。可以在Lakehouse Studio管理 -> 工作空间中查看JDBC连接串![](../.topwrite/assets/image_1728887857029.png) |

+# Lakehouse Java SDK 简介
+
+Lakehouse 为您提供名为 `clickzetta-java` 的 Java SDK。通过这个统一的 SDK，您可以获得以下功能：
+
+* 标准 Type 4 JDBC 驱动，方便您通过 JDBC 访问 ClickZetta Lakehouse
+* 实时数据写入 SDK，支持您将实时数据快速写入 ClickZetta Lakehouse
+* 批量数据写入 SDK，支持您将大量数据高效地写入 ClickZetta Lakehouse
+
+## 如何获取
+
+您可以通过 Maven 依赖的方式引入 `clickzetta-java` SDK：
+
+```xml
+<dependency>
+  <groupId>com.clickzetta</groupId>
+  <artifactId>clickzetta-java</artifactId>
+  <version>${version}</version>
+</dependency>
+```
+
+您可以直接访问 Maven 仓库，在其中搜索 `clickzetta-java` 以获取最新的版本更新记录。
+
+* [下载地址一](https://central.sonatype.com/artifact/com.clickzetta/clickzetta-java/versions)
+* [下载地址二](https://mvnrepository.com/artifact/com.clickzetta/clickzetta-java)
+
+## 注意事项
+
+* `clickzetta-java` 支持 Java 8 及以上版本。
+* 当使用 Java 9 及以上版本时，需要添加 JVM 启动参数 `--add-opens=java.base/java.nio=ALL-UNNAMED` 以确保 SDK 正常运行。
+
+## 常见问题及解决方案
+
+1. 问题描述：`javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target`
+
+   解决方案：您可能使用了 Java 的较早期版本（如 11.0.1+13），受 JDK 对 TLSv1.3 实现的问题（[JDK-8211806](https://bugs.openjdk.org/browse/JDK-8211806)）影响。我们推荐您升级到更新、更稳定的生产版本。如果无法升级 Java 版本，可以添加如下 Java 启动参数来规避此问题：`-Djdk.tls.client.protocols=TLSv1.2`
+

+
+```
+jdbc:clickzetta://<instance_name>.<region_id>.api.clickzetta.com/<workspace_name>?<connection_params>
+```
+
+* 连接参数说明：
+
+  * `<instance_name>`：Lakehouse服务实例名称。在开通指定Region的Lakehouse服务实例时，系统会自动分配实例名称。您可以在产品控制台页面找到Lakehouse实例名称。
+
+  * `<region_id>`：服务实例所在的云厂商及区域的代码，如：cn-shanghai-alicloud。所有region\_id详见[云服务和地域](../Supported_Cloud_Platforms.md)。
+
+  * `<workspace_name>`：工作空间名称。
+
+  * `<connection_params>`：支持使用`=`格式定义参数，多个参数之间用`&`符号分隔。常用参数如下表所示：
+
+| 参数                                | 取值                                                                     |
+| --------------------------------- | ---------------------------------------------------------------------- |
+| username                          | Clickzetta登录用户名                                                        |
+| password                          | 登录用户密码                                                                 |
+| schema                            | 指定默认连接的schema，可选                                                       |
+| virtualCluster                    | 配置JDBC连接默认使用的虚拟集群，可选。如不选择指定，需要连接后通过SQL命令`use vcluster <vc_name>`指定方可使用 |
+| use\_http=true                    | 是否使用http协议，默认是https。当使用private link连接时需要指定该参数                          |
+| use\_oss\_internal\_endpoint=true | 是否使用http协议，默认是false。如果您使用的服务是阿里云支持查询时强制使用 OSS 内网 Endpoint。             |
+
+## 驱动类名
+
+`com.clickzetta.client.jdbc.ClickZettaDriver`
+
+## 初始化 JDBC 连接
+
+`clickzetta-java` 提供的 JDBC 驱动支持两种方式创建 Connection：
+
+1. 通过 JDBC URL 创建 Connection：
+   ```java
+   try {
+       Class.forName("com.clickzetta.client.jdbc.ClickZettaDriver");
+   } catch (ClassNotFoundException e) {
+       e.printStackTrace();
+       System.exit(1);
+   }
+   Connection conn = DriverManager.getConnection("jdbc:clickzetta://instance.api.clickzetta.com/workspace?schema=schema&vcluster=cluster", username, password);
+   ```
+
+* Lakehouse url可以在Lakehouse Studio管理-》工作空间中看到jdbc连接串以查看![](../.topwrite/assets/image_1739177196184.png)
+
+2. 通过 `ClickZettaClient` 创建 Connection：
+   ```java
+   ClickZettaClient client = ClickZettaClient.newBuilder()
+    .instance("instanceName")
+    .service("service")
+    .username("username")
+    .password("password")
+    .vcluster("cluster")
+    .schema("schema")
+    .build();
+   Connection conn = client.getJdbcConnection();
+   ```
+
+## 进行查询
+
+`clickzetta-java` 提供了完整的 JDBC 标准接口，您可以使用熟悉的 JDBC API 进行数据查询。以下是一些示例：
+
+### 示例 1：查询并打印结果
+
+```java
+import java.sql.Connection;
+import java.sql.DriverManager;
+import java.sql.ResultSet;
+import java.sql.ResultSetMetaData;
+import java.sql.Statement;
+
+public class SimpleJdbcDemo {
+    public static void main(String[] args) throws Exception {
+        if (args.length != 3) {
+            System.out.println("输入参数：jdbcUrl, username, password");
+            System.exit(1);
+        }
+        String jdbcUrl = args[0];
+        String username = args[1];
+        String password = args[2];
+
+        Connection conn = DriverManager.getConnection(jdbcUrl, username, password);
+        Statement stmt = conn.createStatement();
+        ResultSet resultSet = stmt.executeQuery("SELECT * FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live LIMIT 10");
+        ResultSetMetaData rsmd = resultSet.getMetaData();
+        int count = rsmd.getColumnCount();
+        while (resultSet.next()) {
+            for (int i = 1; i <= count; i++) {
+                System.out.print(rsmd.getColumnName(i) + ":" + resultSet.getObject(i) + " ");
+            }
+            System.out.println();
+        }
+        stmt.close();
+        conn.close();
+    }
+}
+```
+
+* Lakehouse url可以在Lakehouse Studio管理-》工作空间中看到jdbc连接串以查看![](../.topwrite/assets/image_1739177196184.png)
+
+### 示例 2：插入数据
+
+```java

+        stmt.close();
+        conn.close();
+      
+
+    }
+}
+```

+## 实时写入原理
+
+实时写入Lakehouse的SDK是一种高效的数据流处理工具，它允许用户将数据实时地上传并存储到Lakehouse中。以下是实时写入的工作原理：
+
+1. **SDK上传数据**：用户通过SDK将数据实时上传到Lakehouse的Ingestion Service。
+2. **Ingestion Service处理**：Ingestion Service接收到数据后，直接将数据写入到Lakehouse的表中，此时数据以临时中间文件的形式存储，这个阶段称为**混合表**。
+3. **查询实时数据**：在数据提交之前，用户即可查询（select）到这些实时写入的新数据，但这些数据对于table stream、materialized view和dynamic table来说是不可见的。
+4. **数据提交**：新写入的数据会在大约一分钟后自动提交，提交后，table stream、materialized view和dynamic table都能够读取这部分数据。
+5. **混合表变成普通表**：在数据提交后，后台进程会将混合表合并变成普通表，合并完成后用户可以执行更新操作（update/merge/delete）。
+
+## 适用场景
+
+实时写入Lakehouse的SDK适用于以下场景：
+
+* **短间隔数据导入**：如果您的应用场景要求在非常短的时间间隔内（如5分钟或更短）导入数据，实时写入SDK可以满足您的需求。
+* **频繁小量数据提交**：对于需要频繁提交数据，但每次提交的数据量不大的情况，实时写入SDK提供了一个高效的解决方案。
+* **实时数据分析**：实时写入SDK适合需要对数据进行即时分析和响应的应用，例如实时监控、事件追踪和实时报告等。
+
+## 注意事项
+
+* 实时写入的数据可以秒级查询。
+* 实时写入数据目前只能通过内部提供的 Flink Connector 中支持 schema change 的 sink 算子（单并发）来实现实时的表结构变化感知。在其他场景下进行表结构更改时，需要先停止实时写入任务，然后在表结构变更后一段时间（大约90分钟）后，重新启动任务。
+* table stream、materialized view 和 dynamic table 只能显示已经提交的数据。实时任务写入的数据需要等待 1 分钟才能确认，因此 table stream 也需要等待 1 分钟才能看到。
+
+## 通过客户端创建实时数据流
+
+要创建实时数据流，首先需要使用 Lakehouse 客户端（client）：
+
+```java
+RowStream stream = client.newRealtimeStreamBuilder()
+.operate(RowStream.RealTimeOperate.APPEND_ONLY)
+.options(options)
+.schema(schema)
+.table(table)
+.build();
+// 关闭流，释放资源
+stream.close();
+```
+
+operate：传入一个枚举值，实时接口支持 RowStream.RealTimeOperate.APPEND\_ONLY 和 RowStream.RealTimeOperate.CDC。
+options：用于传入实时写入流的参数，具体见下文的 options 说明。
+
+## 选项（Options）
+
+可以将以下选项（options）传入到实时数据流中，用于控制写入数据的行为。这些参数均为选填，推荐使用默认参数。
+
+```SQL
+Options options = Options.builder()
+.withFlushMode(FlushMode.AUTO_FLUSH_BACKGROUND)
+            .withMutationBufferLinesNum(50000)
+            .withMutationBufferMaxNum(50)
+            .withMutationBufferSpace(20 * 1024 * 1024)
+            .withFlushInterval(10 * 1000)
+            .withRequestFailedRetryEnable(true)
+            .withRequestFailedRetryTimes(5)
+            .withRequestFailedRetryInternalMs(5 * 1000)
+            .withRequestFailedRetryLogDebugEnable(true)
+            .withRequestFailedRetryStatus(
+                    RegisterStatus.RetryStatus.THROTTLED,
+                    RegisterStatus.RetryStatus.INTERNAL_ERROR,
+                    RegisterStatus.RetryStatus.FAILED,
+                    RegisterStatus.RetryStatus.PRECHECK_FAILED)
+            .build();
+```
+
+**参数说明**
+
+| 类别 | 参数 | 默认值 | 说明 |
+| :--- | :--- | :--- | :--- |
+| 写入性能相关参数 | withFlushMode | FlushMode.AUTO_FLUSH_BACKGROUND | 数据刷写方式，目前支持：<br>FlushMode.AUTO_FLUSH_SYNC：每次等待上次刷新完成后才进行下一步写入。<br>FlushMode.AUTO_FLUSH_BACKGROUND：异步刷新，允许多个写入同时进行，不需要等待前一次写入完成。 |
+| 写入性能相关参数 | withMutationBufferLinesNum | 100 | 每个 buffer 中的数据条数的积攒限制，积攒达到后则会发送至服务端。当达到此限制时，数据将被实际 flush 提交至服务端。如果一次导入的数据量达到 MB 级别，可以调大此参数以加快导入速度。数据提交至服务端的条件是 MutationBufferLinesNum 或 withFlushInterval 中任意一个优先达到。 |
+|          | withMutationBufferMaxNum             | 5                                    | 在数据提交过程中，`withMutationBufferLinesNum` 指定了在达到一定数量的数据条目后进行发送，这是一个触发异步发送的阈值。而 `withMutationBufferMaxNum` 则定义了可以同时存在的缓冲区（buffer）的最大数量。即使前一个缓冲区的数据还未完全写入，只要缓冲区的数量没有超过 `withMutationBufferMaxNum` 指定的限制，就可以继续向新的缓冲区写入数据。这允许系统在处理和发送数据时实现更高的并发性，因为不必等待所有缓冲区都清空才能继续写入新数据。简而言之，`withMutationBufferMaxNum` 相当于jdbc连接池 |
+| 写入性能相关参数 | withMutationBufferSpace | 5 * 1024 * 1024 (5MB) | 当达到此限制时，数据将被实际 flush 提交至服务端。如果一次导入的数据量达到 MB 级别，可以调大此参数以加快导入速度。数据提交至服务端的条件是 withMutationBufferSpace 或 withMutationBufferLinesNum 中任意一个优先达到。 |
+| 写入性能相关参数 | withFlushInterval | 10 * 1000 (10秒) | 当达到此时间限制时，数据将被实际 flush 提交至服务端。数据提交至服务端的条件是 withMutationBufferSpace 或 withMutationBufferLinesNum 中任意一个优先达到。 |
+| 重试机制相关参数 | withRequestFailedRetryEnable | FALSE | 是否开启 mutate 失败重试机制。取值为 TRUE 或 FALSE。 |
+|          | withRequestFailedRetryTimes          | 5                                    | mutate 失败，重试最大次数。                                                                                                                                                                                                                                                                                           |
+| 重试机制相关参数 | withRequestFailedRetryInternalMs | 5000 (5秒) | 失败重试间隔时间，单位毫秒（ms）。 |
+|          | withRequestFailedRetryLogDebugEnable | FALSE                                | 是否开启debug日志                                                                                                                                                                                                                                                                                                 |
+|          | withRequestFailedRetryStatus         | RegisterStatus.RetryStatus.THROTTLED | 根据哪种错误原因进行重试，默认是RegisterStatus.RetryStatus.THROTTLED。多个值使用逗号隔开 取值 RegisterStatus.RetryStatus.THROTTLED RegisterStatus.RetryStatus.INTERNAL\_ERROR RegisterStatus.RetryStatus.FAILED RegisterStatus.RetryStatus.PRECHECK\_FAILED                                                                             |
+
+## 写入数据（Row）
+
+通过 `stream.createRow` 方法创建具体的数据对象（Row），并通过 `row.setValue` 方法将数据封装到 Row 对象中。
+
+**Row** **row** = stream.createRow(Stream.Operator.INSERT);
+
+row\.setValue("id", t);
+
+row\.setValue("name", String.valueOf(t));
+
+stream.apply(row);
+
+* 当 Stream 创建为 `RowStream.RealTimeOperate.APPEND_ONLY` 时，仅能创建 `Stream.Operator.INSERT` 类型的 Row。
+
+* 当 Stream 创建为 `RowStream.RealTimeOperate.CDC` 时，以下所有 Row 类型均可使用：
+
+  * `Stream.Operator.INSERT`：插入行，如果目标行已存在则报错。
+  * `Stream.Operator.DELETE`：删除行，如果目标行不存在则报错。
+  * `Stream.Operator.UPDATE`：更新行，如果目标行不存在则报错。
+  * `Stream.Operator.UPSERT`：插入行，如果目标行已存在则更新该行。
+  * `Stream.Operator.INSERT_IGNORE`：插入行，如果目标行已存在则自动忽略。
+
+## 数据提交到服务端
+
+通过调用 `((RealtimeStream)stream).flush()` 方法，数据会提交到服务端。如果没有调用该方法，则数据根据 withMutationBufferSpace、withMutationBufferLinesNum 或 withFlushInterval 中任意一个条件优先达到时，数据将被发送到服务端。
+

+        realtimeStream.close();
+        client.close();
+    }
+}
+```
+
+## CDC实时写入
+
+Lakehouse支持数据库的CDC（Change Data Capture）功能，以流的方式将数据写入到Lakehouse表中，并实时更新表数据。同步过程通过RealtimeStream实时更新插入和删除行操作来实现。同时，支持使用Flink connector和IGS SDK进行数据写入。在创建表时，需要设置主键以确保数据的唯一性和一致性。
+
+### 创建表
+
+在创建Lakehouse表时，需要指定主键。CDC写入会根据主键进行数据去重，以确保数据的准确性。虽然创建的主键表支持SQL操作，建议通过实时写入流进行数据写入。以下是一个创建表的示例：
+
+```sql
+CREATE TABLE igs_test_upsert (
+    id INT PRIMARY KEY,
+    event VARCHAR(100),
+    event_time STRING
+);
+```
+
+### IGS SDK实时写入流
+
+#### 创建实时写入流
+
+使用IGS SDK创建实时写入流，需要指定操作类型（CDC）和相关选项。以下是一个创建实时写入流的示例：
+
+```java
+RowStream stream = client.newRealtimeStreamBuilder()
+    .operate(RowStream.RealTimeOperate.CDC)
+    .options(options)
+    .schema(schema)
+    .table(table)
+    .build(); // 关闭流，释放流资源，必须调用
+stream.close();
+```
+
+#### 指定操作类型
+
+根据需求，可以指定不同的操作类型：
+
+* `Stream.Operator.UPSERT`：插入或更新行。如果目标行不存在，则插入；如果已存在，则更新。
+* `Stream.Operator.DELETE_IGNORE`：删除行。如果目标行不存在，则自动忽略。
+
+#### 使用原生Java Sdk写入
+
+```java
+Row row = stream.createRow(Stream.Operator.UPSERT); // 插入或更新行
+Row rowToDelete = stream.createRow(Stream.Operator.DELETE_IGNORE); // 删除行
+```
+
+### 使用Lakehouse实时同步功能写入
+
+参考文档[多表实时同步](../realtime_sync.md)
+
+### 使用FLINK CONNECTOR写入
+
+Flink connector是基于RealtimeStream SDK封装的，用于实现实时数据同步。查看[Flink Connector](../flink-write-connector.md)

+### 分析频率建议
+
+* **每日监控**: 执行总体概览和失败作业分析
+* **每周分析**: 运行完整的忙闲程度和表使用分析
+* **每月评估**: 进行缓存效率和资源规划分析
+
+建议将常用查询保存为视图，便于重复使用。
+
+### 优化行动指南
+
+* **高执行时间作业**: 检查SQL优化机会，尝试用Dynamic Table的增量计算链路降低计算量，减少执行时间；
+* **低缓存命中率**: 调整分析型计算集群的自动关机时间，在查询高峰期尽量不关机，避免丢失缓存；
+* **高频访问表**: 考虑分区、索引优化；
+* **资源不均衡**: 重新分配workspace内的计算集群资源规格，对频繁使用的计算集群，如果希望降低作业执行时间，可以适当扩容。

+# Lakehouse作业历史
+
+## 概述
+
+Lakehouse 作业历史页面（Job Profile）为您提供了一个直观的方式来查看过去 7 天内在 Lakehouse 账户中执行的查询的详细信息。您可以通过该页面查看包括使用 JDBC 接口提交的任务、Studio 临时查询、Studio 周期调度任务在内的历史作业列表。本指南将帮助您分析运行出错或运行缓慢的作业，并提供相应的解决方案。
+
+## 作业历史搜索
+
+* 支持根据 SQL 作业的作业 ID 进行搜索。
+* 支持根据状态搜索：
+  * setup: SQL 初始化阶段，包含编译优化等操作。
+  * resuming_cluster: 等待启动 VC 耗时，如果长时间未拉起，请联系技术支持。
+  * queued: 作业排队等待资源，如果耗时较长，建议查看 VC 资源是否占满，或考虑扩容 VC。
+  * running: SQL 处理数据时间，可以点击诊断查看每个算子耗时。
+  * finish: 运行结束，部分作业可能在这一阶段进行清理过程，会产生耗时。
+* 支持按耗时筛选
+* 支持按时间筛选，目前最多能查询到近七天的 10,000 条作业。
+* 支持按作业运行的集群名称进行筛选
+* 支持按作业的提交人进行筛选
+* 支持根据 queryTag 筛选
+  用户在提交 SQL 时，可以通过命令 `set query_tag=""` 来标记作业来源或为作业打标，并在此界面进行过滤。
+  * 在 Studio 界面设置 query_tag，选中两条 SQL 同时执行：
+  ```SQL
+      set query_tag="test";
+      select 1;
+  ```
+  * 在 JDBC URL 中添加 query_tag，这样提交的每条 SQL 都会带上 query_tag 用来标识来源，可以在页面中进行过滤。
+  ```text
+  jdbc:clickzetta://instance.region_id.api.clickzetta.com/default?schema=public&query_tag=test
+
+  ```
+  * 在 Python 代码中设置 query_tag
+  ```python
+  # 建立连接 
+  conn = connect(username='',
+   password='', 
+  service='region_id.api.clickzetta.com', 
+  instance='demo_instance',
+   workspace='', schema='public', vcluster='default') 
+  # 执行 SQL 
+  cursor = conn.cursor() 
+  my_param["hints"]["query_tag"] ="test"
+  cursor.execute('select 1;', parameters=my_param)
+
+  ```
+* 作业的默认 Schema（即提交 SQL 时运行的上下文环境），可以通过 `select current_schema()` 获取。
+
+## 分析运行出错的作业
+
+当作业运行失败时，您可以通过作业的 Job Profile 中的详情来查看失败原因。以下是一些常见的失败原因及解决方法：
+
+### SQL语法错误
+
+**错误示例**：
+
+```SQL
+执行 select * from ttt;
+报错 :CZLH-42000:[1,15] Semantic analysis exception - table or view not found - uat_demo_project.`public`.ttt
+```
+
+**错误码 CZLH-42000** 表示与 SQL 语言解析相关的错误。[1,15] 表示错误发生在 SQL 的第 1 行第 15 列。在这个例子中，原因是 `ttt` 表不存在。请注意，如果您通过 Studio 开发界面提交任务，由于开发中的作业编辑器会带有描述信息，这些信息并不会提交到 SQL 引擎，因此正确的行号应该减去前面的描述信息行数。您可以通过作业详情中的作业内容查看正确的位置关系，或者在 SQL 编辑器中找到错误的位置。
+
+## 分析运行缓慢的作业
+
+运行缓慢的作业可能在编译阶段、Virtual Cluster 拉起阶段或执行阶段出现问题。以下是针对这些阶段的分析和解决方法：
+
+### 编译阶段
+
+**问题现象**：作业状态显示为“初始化”。
+
+**可能原因及解决措施**：
+
+1. **执行计划复杂**：作业可能需要较长时间进行优化。请耐心等待，正常情况下不会超过 10 分钟。
+2. **编译资源被占满**：如果您一瞬间提交了大量 SQL，可能导致编译资源不足。请减少提交 SQL 的频率。如有大量高并发查询需求，请提交工单寻求帮助。
+
+### 拉起virtual cluster阶段
+
+**问题现象**：作业状态显示为“集群启动中”。（当前状态为正在拉起计算集群）
+
+### 等待执行阶段
+
+**问题现象**：作业状态显示为“等待执行”。
+
+**可能原因及解决措施**：
+1.  **当前集群的计算资源不足**：您可以通过界面筛选查看当前正在运行的作业。可能因大量作业正在运行导致资源等待。可以考虑扩容资源，或者终止正在运行的大作业以释放资源。
+
+### 执行阶段
+
+**问题现象**：作业状态显示为“正在执行中”。在这一阶段，您可以点进去查看每个算子的执行情况。
+
+**可能原因及解决措施**：
+1.  **等待资源**：作业可能在等待资源分配。请检查资源使用情况，如有需要，请提交工单寻求帮助。
+2.  **数据读取速度慢**：作业可能因为数据读取速度慢而导致执行缓慢。请检查数据存储和读取策略，如有需要，请优化数据存储结构或调整读取策略。
+
+### 分享给其他人诊断
+
+进入作业详情页面后，点击“分享”按钮，即可将作业分享给其他人。接收者无需登录即可查看内容。![](.topwrite/assets/image_1740557522715.png =774)
+如有疑问或需要进一步帮助，请复制上方链接并联系 Lakehouse 团队，我们将为您诊断并解决问题。
+
+## 查看执行计划和Operator详情
+
+在执行阶段，您可以通过点击正在执行的 Operator 来查询具体的步骤和策略。例如，将鼠标悬停在具体的 Operator 上，可以对应到 SQL 中具体执行的算子。这有助于您发现具体是哪个 Operator 导致作业缓慢。

+# JSON数据格式简介
+
+JSON（JavaScript Object Notation）是一种轻量级、易于阅读和编写的半结构化数据格式。它基于JavaScript的一个子集，但是JSON是独立于语言的，许多编程语言都有JSON数据格式的解析和生成代码。JSON格式使用文本表示简单的数据结构，如对象、数组、字符串、数字和布尔值。JSON格式具有良好的可读性和简洁性，使其成为理想的数据交换格式。
+
+# LakeHouse中的JSON类型
+
+在LakeHouse中，JSON类型的数据可以高效地存储和查询。JSON数据在LakeHouse中会被解析，并根据数据的实际结构进行优化存储。以下是LakeHouse中JSON类型的一些特点：
+
+1. 查询性能：使用JSON类型相比于String类型在查询性能上有明显优势，因为LakeHouse会对JSON数据进行列裁剪，减少不必要的数据扫描。
+2. 数据重排：解析过程中，JSON对象的数据可能会被重新排序，因此输入和输出的JSON数据可能在键的顺序上不一致。
+3. 数字解析：解析JSON数字时，LakeHouse会优先尝试将其解析为bigint类型。如果数字超出bigint的范围，则会将其解析为double类型。需要注意的是，double类型可能会有精度损失。
+4. 错误处理：使用函数解析JSON数据时，LakeHouse会进行校验。对于非法的JSON字符串，会返回NULL值；而在声明JSON常量时，非法的JSON字符串会导致错误。
+
+此外，LakeHouse在写入过程中会根据实际的JSON Schema，将出现频次高的字段按照列存储的方式存储，以提高存储和查询效率。例如：
+
+```SQL
+CREATE TABLE json_table AS
+SELECT  parse_json(s) as j
+FROM VALUES
+('{"id": 1, "value": "200"}'),
+('{"id": 2, "value": "300"}'),
+('{"id": 3, "value": "400", "extra": 1}'),
+('{"value": "100"}') as t(s);
+```
+
+1. 对于上面的数据，LakeHouse 检测出 id 和 value 出现频次高，分别适合用 bigint 和 string 类型列式存储，则会在内部以类似 struct\<id:bigint, value:string> 的结构存储。在后续的查询过程中，如果只读取id字段且转换为bigint，如`SELECT json_extract_bigint(j, '$.id')`，则可以直接按列读取 id 字段，并消除类型转换的开销。
+2. 对于出现频次低的 extra 字段，则保留 json 结构且用更加紧凑的表示存储，避免产生过于稀疏的数据。
+
+**限制**
+
+* 不支持对JSON类型的比较操作，也不支持对JSON类型进行`ORDER BY`、`GROUP BY`或作为`JOIN`的key等。
+* 不支持作为cluster key、primary key、partition key
+* JSON字符串最大长度为16 MB。批量、实时导入时对字段进行长度校验。如果您导入数据时有大于16MB的数据您可以修改表的Properties来修改如下将json长度设置为32MB
+
+```
+ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.json.bytes"="33554432");
+```
+
+## 创建JSON列的表
+
+要创建包含JSON类型列的表，可以使用以下SQL语句：
+
+```sql
+CREATE TABLE json_example
+(
+    id bigint,
+    data json
+);
+```
+
+## 构建JSON数据
+
+### JSON常量
+
+在SQL查询中，可以使用JSON常量来表示JSON数据。例如：
+
+```sql
+SELECT
+JSON 'null',
+JSON '1',
+JSON '3.14',
+JSON 'true',
+JSON 'false',
+JSON '{"id":11,"name":"Lakehouse"}',
+JSON '[0, 1]';
+
+-- !query output
++-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
+| JSON 'null' | JSON '1' | JSON '3.14' | JSON 'true' | JSON 'false' | JSON '{"id":11,"name":"Lakehouse"}' | JSON '[0, 1]' |
++-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
+| null        | 1        | 3.14        | true        | false        | {"id":11,"name":"Lakehouse"}        | [0,1]         |
++-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
+```
+
+### 语法
+
+```SQL
+--键名访问JSON对象中的字段
+json_column['key']['key']...
+--通过索引访问JSON数组中的元素
+json_array[index]
+```
+
+**参数说明**
+
+* json\_column:表示一个JSON字段，类型为JSON对象。通过键名（`key`），指定为字符串，来定位并检索JSON对象内的特定数据字段。使用单个方括号`[]`可以访问对象的一级字段；而嵌套使用双方括号`[][]`则能够深入检索对象的二级或更深层次的字段。
+* json\_array:数组类型的JSON，用来根据index访问 JSON array的元素，起始值为0

+```
+
+### 使用函数
+
+### 使用函数(将STRING格式的JSON转化为字符串)
+
+`parse_json`函数可以将String类型的JSON字符串解析为JSON类型。例如：
+
+```SQL
+SELECT parse_json(s) is null, parse_json(s)
+FROM VALUES ('null'),
+            ('1'),
+            ('3.14'),
+            ('true'),
+            ('false'),
+            ('{"id":11,"name":"Lakehouse"}'),
+            ('[0, 1]'),
+            (''),
+            ('invalid') as t(s);
++-------------------------+------------------------------+
+| (parse_json(s)) IS NULL |        parse_json(s)         |
++-------------------------+------------------------------+
+| false                   | null                         |
+| false                   | 1                            |
+| false                   | 3.14                         |
+| false                   | true                         |
+| false                   | false                        |
+| false                   | {"id":11,"name":"Lakehouse"} |
+| false                   | [0,1]                        |
+| true                    | null                         |
+| true                    | null                         |
++-------------------------+------------------------------+
+```
+
+* 如果parse\_json的参数为非法json字符串，则返回SQL null，is null的结果为true
+* 如果输入字符串为`'null'`，则它会被解释为JSON null值，is null的结果为false
+
+### json\_array/json\_object
+
+类似array/named\_struct，可以根据已有的数据构造出对应的json类型
+
+```SQL
+SELECT json_array(), json_array(NULL),json_array(NULL::int, 1, TRUE, FALSE, NULL::int, "a", 1.2, 1.3d);
++----------------+--------------------+--------------------------------------------------------------------------------------+
+| `json_array`() | `json_array`(NULL) | `json_array`(CAST(NULL AS int), 1, true, false, CAST(NULL AS int), 'a', 1.2BD, 1.3d) |
++----------------+--------------------+--------------------------------------------------------------------------------------+
+| []             | [null]             | [null,1,true,false,null,"a","1.2",1.3]                                               |
++----------------+--------------------+--------------------------------------------------------------------------------------+
+
+SELECT json_object(), json_object('k', NULL), json_object('k1', json_array(1, "a"), "k2", array(1, 2, 3));
+-- !query output
++-----------------+--------------------------+-------------------------------------------------------------------+
+| `json_object`() | `json_object`('k', NULL) | `json_object`('k1', `json_array`(1, 'a'), 'k2', `array`(1, 2, 3)) |
++-----------------+--------------------------+-------------------------------------------------------------------+
+| {}              | {"k":null}               | {"k1":[1,"a"],"k2":[1,2,3]}                                       |
++-----------------+--------------------------+-------------------------------------------------------------------+
+```
+
+## 类型转换
+
+在LakeHouse中，可以使用`::json`或`CAST`函数将其他类型转换为JSON类型。以下是一些类型转换的例子：
+
+|            |               |
+| ---------- | ------------- |
+| Json       | SQL           |
+| Object     | Struct        |
+| Array      | Array         |
+| String     | string        |
+| Number     | bigint/double |
+| true/false | bool          |
+| Null       | 无对应类型         |
+| 无对应类型      | binary        |
+
+* 不存在于表格中的类型转换，会先将其转换为可以转换的类型（大多数情况为string类型），再转换为目标类型，例如cast(1.2 as json) 1.2为decimal类型，会先转换为string类型，进一步转换为json类型，结果是JSON '"1.2"'，而不是JSON '1.2'。
+* 需要注意的是cast(string as json)的语义和parse\_json(string)的语义并不一致,parse\_json 会尝试将 JSON 字符串解析成 JSON 对象，如果JSON格式不正确，则会生成 NULL而cast(string to json)**会将字符串整体当做JSON中的string类型,所以如果您是一个json格式字符串转化时应该使用parse\_json**
+  具体案例

+
+需要注意的是，`cast(string as json)`和`parse_json(string)`的语义并不一致。`parse_json`会尝试将JSON字符串解析成JSON对象，如果JSON格式不正确，则会生成NULL；而`cast(string to json)`会将字符串整体当做JSON中的string类型。

+
+# 使用SDK（igs/bulkload）写入JSON
+
+Lakehouse 支持给 JSON 类型的列写入 String 类型的字符串，系统在导入的时候会自动将字符串解析成 JSON 类型，如果用户输入了不符合 JSON 规范或者 CZ 不支持的 JSON 字符串，系统会报错并停止导入。
+
+# 导出JSON数据
+
+Lakehouse 支持以字符串的形式导出 JSON 数据。
+
+# 查询JSON数据
+
+查询JSON数据需要使用`json_extract`系列函数，通过JSON path获取需要的数据。以下是一些查询JSON数据的例子：

+* json\_extract
+* json\_extract\_boolean
+* json\_extract\_float
+* json\_extract\_double
+* json\_extract\_int
+* json\_extract\_bigint
+* json\_extract\_string
+* json\_extract\_date
+* json\_extract\_timestamp
+
+### json path规范
+
+json\_extract的第二个参数为json path，可以参考[json path规范](https://goessner.net/articles/JsonPath/)
+
+* "$"表示根元素
+* ".key"或者"\['key']" 用来查找json object中的key。特殊的，"\[\*]"表示获取所有的value,要求必须是单引号
+* "\[index]" 用来根据index访问 json array的元素，起始值为0。特殊的，"\[\*]"表示所有的元素

+
+使用string查询，执行时间为20.4s。
+
+```SQL

+
+使用json存储数据执行时间为531ms,因为读取的时候进行列裁剪数据大小也会减少,如下图只需要读取153MB数据，string类型需要全量读取454MB数据
+
+```SQL

+## JSON数据类型概述
+
+### 核心优势
+
+云器 Lakehouse 的 JSON 类型相比字符串存储具有显著优势：
+
+1. **查询性能提升**：JSON 列支持列裁剪，只读取需要的字段，性能提升可达 40 倍
+2. **智能存储优化**：高频字段自动列式存储，低频字段紧凑 JSON 存储
+3. **自动类型推断**：数字优先解析为 bigint，超出范围自动转为 double
+4. **原生函数支持**：丰富的 json_extract_* 函数系列，类型安全转换
+
+### 数据存储机制
+
+```sql
+-- 云器Lakehouse自动优化存储策略
+CREATE TABLE user_profiles (
+    id INT,
+    profile JSON  -- 智能存储：高频字段列式，低频字段JSON
+);
+
+-- 内部优化示例：
+-- 高频字段如 id, name 自动列式存储
+-- 低频字段如 extra_metadata 保持JSON结构
+INSERT INTO user_profiles VALUES 
+(1, parse_json('{"id": 1, "name": "张三", "age": 30, "extra_metadata": {"hobby": "篮球"}}')),
+(2, parse_json('{"id": 2, "name": "李四", "age": 25, "city": "上海"}')),
+(3, parse_json('{"id": 3, "name": "王五", "age": 35, "department": "技术部"}'));
+```

+
+***
+
+## 基础语法
+
+### 创建JSON表
+
+```sql
+-- 基础JSON表结构
+CREATE TABLE json_example (
+    id INT,
+    data JSON,           -- 原生JSON类型
+    data_str STRING      -- 字符串形式的JSON（对比用）
+);
+```
+
+### 插入JSON数据
+
+```sql
+-- 方法1：使用parse_json函数（推荐）
+INSERT INTO json_example VALUES (
+    1, 
+    parse_json('{"name": "张三", "age": 30, "city": "北京"}'),
+    '{"name": "张三", "age": 30, "city": "北京"}'
+);
+
+-- 方法2：使用json_object构建
+INSERT INTO json_example VALUES (
+    2,
+    json_object('name', '李四', 'age', 25, 'hobbies', json_array('篮球', '旅游')),
+    null
+);
+
+-- 方法3：直接使用JSON字面量
+INSERT INTO json_example VALUES (
+    3,
+    json'{"name": "王五", "age": 35, "address": {"city": "上海", "zipcode": "200000"}}',
+    null
+);
+```
+
+***
+
+## JSON vs STRING对比
+
+### 性能对比（官方测试数据）
+
+基于云器 Lakehouse 官方 1000 万条记录的性能测试：
+
+| 操作类型   | STRING 存储 | JSON 存储 | 性能提升      |
+| ------ | -------- | ------ | --------- |
+| 字段过滤查询 | 20.4 秒    | 531 ms  | **38 倍**   |
+| 数据扫描量  | 454 MB    | 153 MB  | **66% 减少** |
+| 存储空间   | 100%     | ~80%  | **20% 节省** |
+
+### 函数使用区别
+
+```sql
+-- ❌ 错误：在JSON类型上使用STRING函数
+SELECT get_json_object(json_column, '$.name') FROM table_with_json;
+-- 错误：function 'get_json_object' cannot be resolved, invalid type 'json'
+
+-- ✅ 正确：JSON类型使用json_extract_*系列
+SELECT json_extract_string(json_column, '$.name') FROM table_with_json;
+
+-- ✅ 正确：STRING类型使用get_json_object
+SELECT get_json_object(string_column, '$.name') FROM table_with_string;
+```

+
+## 按平台的迁移指南
+
+### Apache Spark/Hive 用户 ⭐⭐⭐⭐⭐
+
+**兼容性：几乎完美！零学习成本！**
+
+#### ✅ 完全支持的功能
+
+```sql
+-- 1. Spark风格的JSON构建和解析
+SELECT 
+    to_json(map('name', '张三', 'age', 30)) as spark_json,
+    from_json('{"name":"张三","age":30}', 'name STRING, age INT') as spark_struct;
+
+-- 2. collect_list聚合（Spark用户最爱）
+SELECT 
+    department,
+    collect_list(name) as employee_names
+FROM employee_json
+GROUP BY department;
+
+-- 3. explode展开JSON数组
+SELECT 
+    id,
+    hobby
+FROM json_table 
+LATERAL VIEW explode(split(regexp_replace(
+    json_extract_string(json_data, '$.hobbies'), '[\\[\\]"]', ''), ',')) t AS hobby;
+
+-- 4. 窗口函数完美支持
+SELECT 
+    name,
+    salary,
+    row_number() OVER (PARTITION BY department ORDER BY salary DESC) as rank
+FROM employee_json;
+
+-- 5. Hive json_tuple完全兼容
+SELECT 
+    name, age, city
+FROM (
+    SELECT json_tuple(json_string, 'name', 'age', 'city') as (name, age, city)
+    FROM hive_json_table
+) t;
+```
+
+#### 📝 Spark/Hive用户最佳实践
+
+```sql
+-- ✅ 推荐的迁移模式
+CREATE TABLE lakehouse_events (
+    event_id STRING,
+    event_data JSON,
+    
+    -- 生成列：熟悉的字段提取
+    event_type STRING GENERATED ALWAYS AS (json_extract_string(event_data, '$.type')),
+    user_id STRING GENERATED ALWAYS AS (json_extract_string(event_data, '$.user_id')),
+    timestamp_col TIMESTAMP GENERATED ALWAYS AS (
+        cast(json_extract_string(event_data, '$.timestamp') as timestamp)
+    )
+) PARTITIONED BY (event_type);
+
+-- 直接复制Hive查询，无需修改！
+CREATE TABLE lakehouse_table AS 
+SELECT 
+    get_json_object(json_col, '$.user.id') as user_id,
+    get_json_object(json_col, '$.user.name') as user_name,
+    get_json_object(json_col, '$.event.type') as event_type
+FROM source_table
+WHERE get_json_object(json_col, '$.event.type') = 'purchase';
+```
+
+### Snowflake 用户 ⭐⭐
+
+**兼容性：需要重写，但有明确的替代方案**
+
+#### 🔄 Snowflake迁移示例
+
+```sql
+-- ❌ Snowflake原始查询
+-- SELECT 
+--     user_data:name::STRING as name,
+--     user_data:age::INTEGER as age,
+--     user_data:hobbies[0]::STRING as first_hobby
+-- FROM snowflake_table;
+
+-- ✅ 云器Lakehouse等价查询
+SELECT 
+    json_extract_string(user_data, '$.name') as name,
+    json_extract_int(user_data, '$.age') as age,
+    json_extract_string(user_data, '$.hobbies[0]') as first_hobby
+FROM lakehouse_table;
+
+-- ❌ Snowflake FLATTEN
+-- SELECT 
+--     value::STRING as hobby
+-- FROM snowflake_table,
+-- LATERAL FLATTEN(input => user_data:hobbies);
+
+-- ✅ 云器Lakehouse等价方案
+SELECT 
+    trim(hobby) as hobby
+FROM lakehouse_table 
+LATERAL VIEW explode(
+    split(regexp_replace(json_extract_string(user_data, '$.hobbies'), '[\\[\\]"]', ''), ',')
+) t AS hobby;
+```
+
+### PostgreSQL/MySQL 用户 ⭐⭐⭐
+
+**兼容性：函数不同，但逻辑相同**
+
+#### PostgreSQL迁移示例
+
+```sql
+-- ❌ PostgreSQL原始查询
+-- SELECT 
+--     user_data ->> 'name' as name,
+--     (user_data -> 'address' ->> 'city') as city,
+--     user_data #>> '{preferences,0}' as first_pref
+-- FROM postgres_table;
+
+-- ✅ 云器Lakehouse等价查询
+SELECT 
+    json_extract_string(user_data, '$.name') as name,
+    json_extract_string(user_data, '$.address.city') as city,
+    json_extract_string(user_data, '$.preferences[0]') as first_pref
+FROM lakehouse_table;
+```
+
+#### MySQL迁移注意事项
+
+```sql
+-- ❌ MySQL方式（针对字符串）
+-- SELECT JSON_EXTRACT(json_string, '$.name') FROM mysql_table;
+
+-- ✅ 云器Lakehouse方式（区分类型）
+-- 对于STRING类型
+SELECT get_json_object(json_string, '$.name') FROM lakehouse_table;
+
+-- 对于JSON类型  
+SELECT json_extract_string(json_data, '$.name') FROM lakehouse_table;
+```
+
+***
+
+## JSON函数完全指南
+
+### 1. JSON构建函数
+
+```sql
+-- json_object：构建JSON对象
+SELECT json_object() as empty_obj;                    -- {}
+SELECT json_object('key', 'value') as simple_obj;     -- {"key":"value"}
+SELECT json_object(
+    'name', '张三',
+    'age', 30,
+    'hobbies', json_array('篮球', '旅游')
+) as complex_obj;
+-- {"age":30,"hobbies":["篮球","旅游"],"name":"张三"}
+
+-- json_array：构建JSON数组
+SELECT json_array() as empty_arr;                     -- []
+SELECT json_array(1, 2, 3) as number_arr;             -- [1,2,3]
+SELECT json_array('a', 'b', 'c') as string_arr;       -- ["a","b","c"]
+SELECT json_array(1, 'test', true, null) as mixed_arr; -- [1,"test",true,null]
+```
+
+### 2. JSON路径语法
+
+```sql
+-- 基础路径语法
+'$'                    -- 根元素
+'$.field'              -- 对象字段
+'$.nested.field'       -- 嵌套对象字段
+'$[0]'                 -- 数组第一个元素
+'$[*]'                 -- 数组所有元素
+'$.array[0].field'     -- 数组元素的字段
+'$["key.with.dot"]'    -- 包含特殊字符的键（使用单引号）
+
+-- 实际示例
+SELECT 
+    json_extract_string(data, '$.name') as name,
+    json_extract_string(data, '$.address.city') as city,
+    json_extract_string(data, '$.hobbies[0]') as first_hobby,
+    json_extract(data, '$.hobbies[*]') as all_hobbies
+FROM json_table;
+```
+
+### 3. JSON验证和错误处理
+
+```sql
+-- json_valid：验证JSON格式
+SELECT 
+    json_valid('{"name": "test"}') as valid,      -- true
+    json_valid('invalid json') as invalid,       -- false
+    json_valid('null') as null_valid,             -- true
+    json_valid('[]') as array_valid,              -- true
+    json_valid('{}') as object_valid;             -- true
+
+-- 错误处理：不存在的字段返回null
+SELECT 
+    json_extract_string(data, '$.nonexistent') as result  -- 返回 null
+FROM json_table;
+```
+
+***
+
+## JSON与生成列
+
+### 基础用法
+
+```sql
+-- 创建带JSON生成列的表
+CREATE TABLE user_analytics (
+    id INT,
+    user_data JSON,
+    -- 生成列：自动提取JSON字段
+    user_name STRING GENERATED ALWAYS AS (
+        json_extract_string(user_data, '$.name')
+    ),
+    user_age INT GENERATED ALWAYS AS (
+        json_extract_int(user_data, '$.age')
+    ),
+    city STRING GENERATED ALWAYS AS (
+        json_extract_string(user_data, '$.address.city')
+    )
+) COMMENT 'JSON自动字段提取示例';
+
+-- 插入数据：只需提供基础JSON
+INSERT INTO user_analytics (id, user_data) VALUES (
+    1, 
+    parse_json('{"name": "张三", "age": 30, "address": {"city": "北京", "zipcode": "100000"}}')
+);
+
+-- 查询结果：自动包含提取的字段
+SELECT * FROM user_analytics;
+-- 结果包含：id=1, user_name="张三", user_age=30, city="北京"
+```
+
+### 高级生成列应用
+
+```sql
+-- 复杂JSON业务逻辑生成列
+CREATE TABLE order_analysis (
+    id INT,
+    order_json JSON,
+    
+    -- 基础字段提取
+    customer_name STRING GENERATED ALWAYS AS (
+        json_extract_string(order_json, '$.customer.name')
+    ),
+    order_amount DOUBLE GENERATED ALWAYS AS (
+        json_extract_double(order_json, '$.amount')
+    ),
+    
+    -- 业务逻辑生成列
+    amount_level STRING GENERATED ALWAYS AS (
+        if(json_extract_double(order_json, '$.amount') >= 1000, 'HIGH',
+           if(json_extract_double(order_json, '$.amount') >= 500, 'MEDIUM', 'LOW'))
+    ),

+    ),
+    
+    -- 时间维度生成列
+    order_date STRING GENERATED ALWAYS AS (
+        json_extract_string(order_json, '$.order_time')
+    )
+) PARTITIONED BY (order_date);
+```
+
+***
+
+## 验证清单
+
+### 创建后验证（每次必做）
+
+```sql
+-- 1. 创建带生成列的表
+CREATE TABLE orders_test (
+    order_id INT,
+    order_time TIMESTAMP_LTZ,
+    order_json JSON,
+    hour_col INT GENERATED ALWAYS AS (json_extract_int(order_json, '$.hour')),
+    date_str STRING GENERATED ALWAYS AS (json_extract_string(order_json, '$.date'))
+);
+
+-- 2. 验证表结构
+DESCRIBE TABLE orders_test;
+-- ✅ 检查：生成列是否出现在表结构中
+
+-- 3. 测试数据插入
+INSERT INTO orders_test (order_id, order_time, order_json) VALUES 
+(1001, TIMESTAMP '2024-06-19 14:30:00', parse_json('{"hour": 14, "date": "2024-06-19"}'));
+
+-- 4. 验证生成列值
+SELECT order_id, hour_col, date_str FROM orders_test;
+-- ✅ 检查：hour_col=14, date_str='2024-06-19'
+
+-- 5. 验证插入保护机制
+-- INSERT INTO orders_test (order_id, order_json, hour_col) VALUES 
+-- (1002, parse_json('{"hour": 15}'), 999);
+-- ✅ 检查：应该报错"cannot insert or update generated column"
+```
+
+### 跨平台兼容性验证
+
+```sql
+-- 6. 验证函数兼容性
+SELECT 
+    -- Hive/Spark风格（应该工作）
+    get_json_object('{"name":"test"}', '$.name') as hive_style,
+    
+    -- JSON类型函数（应该工作）
+    json_extract_string(parse_json('{"name":"test"}'), '$.name') as json_style,
+    
+    -- 聚合函数（应该工作）
+    collect_list('test') as spark_aggregate;
+
+-- 7. 验证性能差异
+-- 对比JSON类型 vs STRING类型的查询性能
+EXPLAIN SELECT json_extract_string(json_col, '$.field') FROM json_table;
+EXPLAIN SELECT get_json_object(string_col, '$.field') FROM string_table;
+```
+
+***
+
+## 性能优化
+
+### 1. 存储优化策略
+
+```sql
+-- 高频字段优化：让系统自动识别并优化存储
+CREATE TABLE optimized_storage AS 
+SELECT parse_json(json_string) as optimized_json 
+FROM VALUES 
+    ('{"id": 1, "name": "张三", "frequent_field": "value1"}'),
+    ('{"id": 2, "name": "李四", "frequent_field": "value2"}'),
+    ('{"id": 3, "name": "王五", "frequent_field": "value3", "rare_field": "rare"}')
+as t(json_string);
+
+-- 系统会自动将id, name, frequent_field列式存储
+-- rare_field保持JSON存储，避免稀疏列
+```
+
+### 2. 查询优化
+
+```sql
+-- ✅ 高性能：使用JSON类型 + 正确函数
+SELECT 
+    json_extract_string(json_data, '$.name'),
+    json_extract_int(json_data, '$.age')
+FROM json_table 
+WHERE json_extract_string(json_data, '$.city') = '北京';
+
+-- ❌ 低性能：使用STRING类型需要全表扫描
+SELECT 
+    get_json_object(string_data, '$.name'),
+    get_json_object(string_data, '$.age')
+FROM string_table 
+WHERE get_json_object(string_data, '$.city') = '北京';
+```
+
+### 3. 通用高性能模式
+
+```sql
+-- 🎯 高性能模式：JSON + 生成列 + 索引
+CREATE TABLE optimized_json (
+    id BIGINT,
+    raw_data JSON,
+    
+    -- 热点字段生成列
+    user_id STRING GENERATED ALWAYS AS (json_extract_string(raw_data, '$.user_id')),
+    timestamp_col TIMESTAMP GENERATED ALWAYS AS (
+        cast(json_extract_string(raw_data, '$.timestamp') as timestamp)
+    ),
+    event_type STRING GENERATED ALWAYS AS (json_extract_string(raw_data, '$.event_type'))
+) PARTITIONED BY (event_type);
+
+-- 为生成列创建索引
+CREATE INDEX idx_user_id ON optimized_json (user_id);
+CREATE INDEX idx_timestamp ON optimized_json (timestamp_col);
+```
+
+***
+
+## 限制和注意事项
+
+### 1. JSON类型限制（通用）
+
+```sql
+-- ❌ 不支持的操作
+
+-- 比较操作
+SELECT * FROM json_table WHERE json_col = parse_json('{"key": "value"}');
+-- 错误：operator not found, json = json
+
+-- 排序操作
+SELECT * FROM json_table ORDER BY json_col;
+-- 错误：require equality comparable type in ORDER BY, but got json
+
+-- 分组操作
+SELECT json_col, COUNT(*) FROM json_table GROUP BY json_col;
+-- 错误：不支持GROUP BY JSON类型
+
+-- 作为JOIN键
+SELECT * FROM table1 t1 JOIN table2 t2 ON t1.json_col = t2.json_col;
+-- 错误：不支持JSON类型作为JOIN键
+```
+
+### 2. 分区和索引限制
+
+```sql
+-- ❌ 不支持作为分区键
+CREATE TABLE partitioned_table (
+    id INT,
+    data JSON
+) PARTITIONED BY (data);  -- 错误：不支持JSON作为分区键
+
+-- ✅ 正确做法：使用生成列作为分区键
+CREATE TABLE partitioned_correct (
+    id INT,
+    data JSON,
+    date_part STRING GENERATED ALWAYS AS (json_extract_string(data, '$.date'))
+) PARTITIONED BY (date_part);
+```
+
+### 3. 路径语法限制
+
+```sql
+-- ❌ 不支持的路径语法
+-- 负数索引：'$[-1]'
+-- 条件过滤：'$[?(@.price > 10)]'
+-- 递归下降：'$..'
+
+-- ✅ 支持的路径语法
+'$.field'              -- 字段访问
+'$.nested.field'       -- 嵌套字段
+'$[0]'                 -- 数组索引
+'$[*]'                 -- 数组所有元素
+'$["field.with.dot"]'  -- 特殊字符字段（单引号）
+```
+
+***
+
+## 常见错误
+
+### 1. 函数类型错误
+
+| 错误现象                                                                       | 原因                 | 解决方案                      |
+| -------------------------------------------------------------------------- | ------------------ | ------------------------- |
+| `function 'get_json_object' cannot be resolved, invalid type 'json'`       | 在JSON类型上使用STRING函数 | 改用`json_extract_string()` |
+| `function 'json_extract_string' cannot be resolved, invalid type 'string'` | 在STRING类型上使用JSON函数 | 改用`get_json_object()`     |
+| `operator not found, json = json`                                          | 尝试比较JSON值          | 提取为基础类型后比较                |
+
+### 2. 路径语法错误
+
+```sql
+-- ❌ 错误的路径语法
+json_extract_string(data, 'name')           -- 缺少$前缀
+json_extract_string(data, '$.key.with.dot') -- 特殊字符需要括号
+
+-- ✅ 正确的路径语法
+json_extract_string(data, '$.name')
+json_extract_string(data, '$["key.with.dot"]')  -- 注意使用单引号
+```
+
+### 3. 平台迁移常见错误
+
+```sql
+-- ❌ Snowflake用户常犯错误
+-- SELECT user_data:name FROM table;  -- 不支持:操作符
+
+-- ❌ PostgreSQL用户常犯错误  
+-- SELECT user_data->'name' FROM table;  -- 不支持->操作符
+
+-- ❌ MySQL用户常犯错误
+-- SELECT JSON_EXTRACT(json_data, '$.name') FROM table;  -- 参数类型错误
+
+-- ✅ 统一的正确语法
+SELECT json_extract_string(user_data, '$.name') FROM table;  -- JSON类型
+SELECT get_json_object(user_string, '$.name') FROM table;    -- STRING类型
+```
+
+***
+
+## 迁移指导
+
+### 分阶段迁移策略
+
+#### 阶段1：评估和准备（1-2周）
+
+```sql
+-- 1. 评估现有JSON使用情况
+SELECT 
+    table_name,
+    column_name,
+    data_type,
+    count(*) as usage_count
+FROM information_schema.columns 
+WHERE data_type LIKE '%json%' OR column_name LIKE '%json%'
+GROUP BY table_name, column_name, data_type;
+
+-- 2. 识别高频JSON操作
+-- 分析现有查询中的JSON函数使用情况
+```
+
+#### 阶段2：兼容性测试（1-2周）
+
+```sql
+-- 3. 创建测试表验证兼容性
+CREATE TABLE migration_test (
+    id INT,
+    old_json_string STRING,     -- 保持原有格式
+    new_json_data JSON,         -- 新的JSON类型
+    -- 双重生成列验证
+    field_old STRING GENERATED ALWAYS AS (get_json_object(old_json_string, '$.field')),
+    field_new STRING GENERATED ALWAYS AS (json_extract_string(new_json_data, '$.field'))
+);
+
+-- 4. 性能基准测试
+-- 对比旧查询 vs 新查询的性能差异
+```
+
+#### 阶段3：渐进迁移（2-4周）
+
+```sql
+-- 5. 新表直接使用JSON类型
+CREATE TABLE new_design_table (
+    id INT,
+    data JSON,
+    -- 关键字段生成列
+    user_id STRING GENERATED ALWAYS AS (json_extract_string(data, '$.user_id')),
+    event_type STRING GENERATED ALWAYS AS (json_extract_string(data, '$.event_type'))
+) PARTITIONED BY (event_type);
+
+-- 6. 现有表添加JSON列
+ALTER TABLE existing_table ADD COLUMN 
+json_data JSON GENERATED ALWAYS AS (parse_json(json_string));
+```
+
+#### 阶段4：全面迁移（根据业务窗口）
+
+```sql
+-- 7. 更新应用代码
+-- 将所有JSON操作切换到新的函数和列
+
+-- 8. 清理旧列（确认稳定后）
+-- ALTER TABLE table_name DROP COLUMN old_json_string;
+```
+
+***

+    }
+  },
+  "items": [{"sku": "PHONE-001", "category": "electronics", "price": 6999.00}],
+  "payment": {"amount": 7098.00}
+}'), CURRENT_DATE()),
+('ORD-2024-002', parse_json('{
+  "customer": {
+    "id": 10002, 
+    "name": "李四",

+
+**云器Lakehouse动态Schema解决方案**：
+
+```sql
+-- 创建促销数据表
+CREATE TABLE IF NOT EXISTS promotion_orders_json (
+    order_id STRING,
+    order_data JSON,
+    created_date DATE DEFAULT CURRENT_DATE()
+);
+
+-- 同一表存储不同结构的促销数据
+INSERT INTO promotion_orders_json VALUES
+-- VIP折扣：固定金额结构
+('ORD-VIP-001', parse_json('{"customer": {"name": "张三"}, "promotion": {"type": "vip_discount", "amount": 500}}'), CURRENT_DATE()),
+-- 闪购：百分比结构  
+('ORD-FLASH-001', parse_json('{"customer": {"name": "李四"}, "promotion": {"type": "flash_sale", "percentage": 0.2}}'), CURRENT_DATE()),
+-- 套装优惠：组合商品结构
+('ORD-BUNDLE-001', parse_json('{"customer": {"name": "王五"}, "promotion": {"type": "bundle_deal", "required_items": 3, "discount_per_item": 50}}'), CURRENT_DATE()),
+-- 优惠券：代码结构
+('ORD-COUPON-001', parse_json('{"customer": {"name": "赵六"}, "promotion": {"type": "coupon", "code": "SAVE20", "discount": 200}}'), CURRENT_DATE());
+
+-- 自适应查询：一个SQL处理所有促销类型
+SELECT

+    json_extract_string(order_data, "$.promotion.type") as promotion_type,
+    -- 根据促销类型自动提取对应字段
+    CASE WHEN json_extract_string(order_data, "$.promotion.type") = 'vip_discount' 
+         THEN json_extract_double(order_data, "$.promotion.amount")
+         WHEN json_extract_string(order_data, "$.promotion.type") = 'coupon' 
+         THEN json_extract_double(order_data, "$.promotion.discount")
+         ELSE 0 
+    END as discount_amount,
+    CASE WHEN json_extract_string(order_data, "$.promotion.type") = 'flash_sale' 
+         THEN json_extract_double(order_data, "$.promotion.percentage") 
+         ELSE 0 
+    END as discount_percentage,
+    CASE WHEN json_extract_string(order_data, "$.promotion.type") = 'bundle_deal' 
+         THEN json_extract_int(order_data, "$.promotion.required_items")

+         ELSE NULL 
+    END as coupon_code
+FROM promotion_orders_json
+WHERE json_extract_string(order_data, "$.promotion.type") IS NOT NULL;
+```

+
+1. **动态Schema适应**：新促销类型零停机自动支持
+2. **结构无关查询**：单一SQL处理多种数据结构
+3. **业务敏捷性**：促销规则变更无需数据库Schema修改
+
+#### 3.1.3 挑战三：实时库存预警的数组聚合计算难题
+
+**技术挑战描述**：
+需要从订单的`items`数组中提取所有SKU并实时统计销量，传统方案需要复杂的触发器或定时ETL作业，延迟高且资源消耗大。
+
+**云器Lakehouse实时流处理解决方案**：
+
+```sql
+-- 创建库存订单数据表
+CREATE TABLE IF NOT EXISTS inventory_orders_json (
+    order_id STRING,
+    order_data JSON,
+    created_date DATE DEFAULT CURRENT_DATE()
+);
+
+-- 插入包含SKU和数量的订单数据
+INSERT INTO inventory_orders_json VALUES
+('ORD-INV-001', parse_json('{"items": [{"sku": "PHONE-001", "qty": 2}], "payment": {"amount": 13998.00}}'), CURRENT_DATE()),
+('ORD-INV-002', parse_json('{"items": [{"sku": "BOOK-001", "qty": 5}], "payment": {"amount": 1495.00}}'), CURRENT_DATE()),
+('ORD-INV-003', parse_json('{"items": [{"sku": "PHONE-001", "qty": 1}], "payment": {"amount": 6999.00}}'), CURRENT_DATE()),
+('ORD-INV-004', parse_json('{"items": [{"sku": "GADGET-001", "qty": 3}], "payment": {"amount": 4797.00}}'), CURRENT_DATE()),
+('ORD-INV-005', parse_json('{"items": [{"sku": "BOOK-001", "qty": 2}], "payment": {"amount": 598.00}}'), CURRENT_DATE());
+
+-- 动态表实现实时库存统计，自动刷新
+CREATE OR REPLACE DYNAMIC TABLE IF NOT EXISTS real_time_inventory
+REFRESH INTERVAL 1 MINUTES
+AS SELECT 
+    json_extract_string(order_data, "$.items[0].sku") as sku,
+    SUM(json_extract_int(order_data, "$.items[0].qty")) as total_sold,
+    COUNT(*) as order_count,
+    MAX(created_date) as last_order_date,
+    -- 实时库存预警阈值计算
+    CASE 
+        WHEN SUM(json_extract_int(order_data, "$.items[0].qty")) > 5 THEN 'high_demand'
+        WHEN SUM(json_extract_int(order_data, "$.items[0].qty")) > 2 THEN 'medium_demand'
+        ELSE 'low_demand'
+    END as demand_level
+FROM inventory_orders_json 
+WHERE json_extract_string(order_data, "$.items[0].sku") IS NOT NULL
+GROUP BY json_extract_string(order_data, "$.items[0].sku");
+
+-- 实时查询库存预警
+SELECT * FROM real_time_inventory 
+WHERE demand_level = 'high_demand' 
+ORDER BY total_sold DESC;
+```
+
+**技术价值**：
+
+1. **流批一体**：动态表自动聚合数据变更

+        ELSE 'basic_device'
+    END as inferred_device_category
+FROM iot_devices_unified
+ORDER BY collected_time DESC;
+```
+
+**技术价值**：
+
+1. **设备即插即用**：新设备类型无需Schema变更
+2. **统一查询接口**：单一SQL支持所有设备类型
+3. **智能字段映射**：COALESCE自动适配不同字段结构
+
+### 3.3 金融场景：复杂风控的实时决策
+

+
+#### 4.3.2 JSON数据更新的替代解决方案
+
+**🚨 重要技术限制**： 经过实际验证，云器Lakehouse不支持`json_set`、`json_insert`、`json_remove`等JSON修改函数。以下是验证过的替代解决方案：
+
+**方案一：JSON完整重构（适用于简单更新**）
+
+```sql
+-- 创建事务演示表
+CREATE TABLE IF NOT EXISTS transaction_demo (
+    customer_id STRING,
+    customer_data JSON,
+    updated_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP()
+);
+
+-- 插入初始数据
+INSERT INTO transaction_demo VALUES
+('10001', parse_json('{"name": "张三", "level": "regular", "profile": {"upgrade_date": null}, "payment": {"vip_discount": 0}}'), CURRENT_TIMESTAMP());
+
+-- 使用parse_json + CONCAT重构JSON对象进行更新
+UPDATE transaction_demo 
+SET customer_data = parse_json(CONCAT(
+    '{"name": "', json_extract_string(customer_data, "$.name"), '", ',
+    '"level": "VIP", ',
+    '"profile": {"upgrade_date": "2024-12-01"}, ',
+    '"payment": {"vip_discount": 500.0}}'
+)),
+updated_time = CURRENT_TIMESTAMP()
+WHERE customer_id = '10001'
+  AND json_extract_string(customer_data, "$.level") != 'VIP';
+
+-- 验证更新结果
+SELECT 
+    customer_id,
+    json_extract_string(customer_data, "$.name") as name,
+    json_extract_string(customer_data, "$.level") as level,
+    json_extract_string(customer_data, "$.profile.upgrade_date") as upgrade_date,
+    json_extract_double(customer_data, "$.payment.vip_discount") as vip_discount
+FROM transaction_demo
+WHERE customer_id = '10001';
+```
+
+**方案二：混合存储策略（推荐用于频繁更新**）
+
+```sql
+-- 频繁更新字段分离存储，稳定数据使用JSON
+CREATE TABLE IF NOT EXISTS hybrid_storage_demo (
+    id INT,
+    user_level STRING,  -- 频繁更新的字段单独存储
+    update_count INT,   -- 频繁更新的字段单独存储
+    user_profile JSON,  -- 稳定的复杂数据用JSON存储
+    last_updated TIMESTAMP DEFAULT CURRENT_TIMESTAMP()
+);
+
+-- 插入混合存储数据
+INSERT INTO hybrid_storage_demo VALUES
+(1, 'VIP', 5, 
+ parse_json('{"preferences": ["electronics", "books"], "address": {"city": "北京", "district": "朝阳区"}}'),
+ CURRENT_TIMESTAMP());
+
+-- 查询混合存储数据
+SELECT 
+    id,
+    user_level,  -- 关系型字段，更新效率高
+    update_count,  -- 关系型字段，更新效率高
+    json_extract_string(user_profile, "$.preferences[0]") as primary_preference,  -- JSON字段，查询灵活
+    json_extract_string(user_profile, "$.address.city") as city  -- JSON字段，结构化存储
+FROM hybrid_storage_demo;
+```

+ORDER BY json_extract_int(data, "$.score") DESC;
+```
+
+### 5.2 最佳实践建议
+
+#### 5.2.1 字段命名规范
+
+**推荐：使用英文字段名**
+
+```sql
+-- 创建最佳实践演示表
+CREATE TABLE IF NOT EXISTS best_practice_demo (
+    id STRING,
+    data JSON
+);
+
+-- 推荐的字段命名方式
+INSERT INTO best_practice_demo VALUES
+('demo001', parse_json('{"user_name": "张三", "user_city": "北京", "user_comment": "产品很好😊", "rating_score": 5}'));
+
+-- 查询演示
+SELECT 
+    json_extract_string(data, "$.user_name") as name,
+    json_extract_string(data, "$.user_city") as city,
+    json_extract_string(data, "$.user_comment") as comment,
+    json_extract_int(data, "$.rating_score") as score
+FROM best_practice_demo;
+```
+
+**谨慎使用：中文字段名**
+
+```sql
+-- 创建中文字段名演示表（不推荐）
+CREATE TABLE IF NOT EXISTS chinese_field_demo (
+    id STRING,
+    data JSON
+);
+
+-- 中文字段名示例（可用但不推荐）
+INSERT INTO chinese_field_demo VALUES
+('demo001', parse_json('{"用户姓名": "张三", "用户城市": "北京", "用户评价": "产品很好😊"}'));
+
+-- 查询中文字段名（语法正确但不推荐）
+SELECT 
+    json_extract_string(data, "$.用户姓名") as name,
+    json_extract_string(data, "$.用户城市") as city,
+    json_extract_string(data, "$.用户评价") as comment
+FROM chinese_field_demo;
+```
+
+#### 5.2.2 特殊字符处理
+
+**安全的内容格式**：
+
+```sql
+-- 创建特殊字符处理演示表
+CREATE TABLE IF NOT EXISTS special_char_demo (
+    id STRING,
+    data JSON
+);
+
+-- 插入包含各种特殊字符的数据
+INSERT INTO special_char_demo VALUES
+('char001', parse_json('{"message": "正常的中文内容和emoji😊", "symbols": "!@#$%^&*()_+-=[]{}|;:,.<>?/", "punctuation": "中文标点：，。；：""''（）【】、？！"}'));
+
+-- 查询特殊字符数据
+SELECT 
+    json_extract_string(data, "$.message") as message,
+    json_extract_string(data, "$.symbols") as symbols,
+    json_extract_string(data, "$.punctuation") as punctuation
+FROM special_char_demo;
+```
+
+### 5.3 问题排查指南
+
+如果遇到中文或emoji显示问题：
+
+1. **检查字段命名**：优先使用英文字段名
+2. **验证JSON格式**：确保JSON格式正确，没有语法错误
+3. **使用标准函数**：统一使用json\_extract\_\*函数
+4. **避免复杂转义**：减少在JSON字符串中使用复杂的转义字符
+5. **编码设置**：确保客户端和数据库的字符编码设置正确
+
+```sql
+-- 问题排查演示查询
+CREATE TABLE IF NOT EXISTS troubleshoot_demo (
+    id STRING,
+    data JSON
+);
+
+-- 正确的数据插入方式
+INSERT INTO troubleshoot_demo VALUES
+('test001', parse_json('{"name": "测试用户", "message": "这是一条测试消息🔧"}'));
+
+-- 验证数据是否正确存储和查询
+SELECT 
+    id,
+    json_extract_string(data, "$.name") as name,
+    json_extract_string(data, "$.message") as message,
+    LENGTH(json_extract_string(data, "$.name")) as name_length,
+    LENGTH(json_extract_string(data, "$.message")) as message_length
+FROM troubleshoot_demo;
+```

+
+## 第六章：技术限制与最佳实践
+
+### 6.1 JSON类型限制总结（验证修正版）
+
+基于完整验证发现的核心限制：
+
+#### 6.1.1 确认支持的功能
+
+**✅ 支持的JSON函数**：
+
+* `parse_json()` - JSON字符串解析
+* `json_extract_string()` - 提取字符串值
+* `json_extract_int()` - 提取整数值
+* `json_extract_double()` - 提取浮点数值
+* `json_extract()` - 通用提取函数
+
+**✅ 支持的语法**：
+
+* `CREATE TABLE IF NOT EXISTS`
+* 完整的DDL操作（CREATE/ALTER/DROP）
+* 数组访问语法 `[0]`, `[1]`
+* 嵌套对象访问 `$.path.to.field`
+* 中文和emoji内容完全支持
+
+#### 6.1.2 确认不支持的功能
+
+**❌ 不支持的JSON函数**：
+
+```sql
+-- 以下函数经验证不被支持：
+-- json_set() - JSON字段更新（重要限制）
+```
+
+**❌ 不支持的操作**：
+
+```sql
+-- 创建限制演示表
+CREATE TABLE IF NOT EXISTS limitation_demo (
+    id INT,
+    json_data JSON
+);
+
+-- 插入测试数据
+INSERT INTO limitation_demo VALUES
+(1, parse_json('{"name": "张三", "score": 85}')),
+(2, parse_json('{"name": "李四", "score": 92}')),
+(3, parse_json('{"name": "王五", "score": 78}'));
+
+-- 以下操作不被支持，会导致错误：
+-- JSON类型不支持直接比较
+-- SELECT * FROM limitation_demo WHERE json_data = parse_json('{}');
+
+-- JSON类型不支持直接排序
+-- SELECT * FROM limitation_demo ORDER BY json_data;
+
+-- JSON类型不支持直接GROUP BY
+-- SELECT json_data, COUNT(*) FROM limitation_demo GROUP BY json_data;
+```
+
+#### 6.1.3 解决方案
+
+```sql
+-- 使用json_extract函数进行比较
+SELECT * FROM limitation_demo 
+WHERE json_extract_string(json_data, "$.name") = '张三';
+
+-- 提取字段后排序
+SELECT 
+    id,
+    json_extract_string(json_data, "$.name") as name,
+    json_extract_int(json_data, "$.score") as score
+FROM limitation_demo 
+ORDER BY json_extract_int(json_data, "$.score") DESC;
+
+-- 提取字段后分组
+SELECT 
+    CASE 
+        WHEN json_extract_int(json_data, "$.score") >= 90 THEN 'excellent'
+        WHEN json_extract_int(json_data, "$.score") >= 80 THEN 'good'
+        ELSE 'average'
+    END as grade,
+    COUNT(*) as count
+FROM limitation_demo 
+GROUP BY CASE 
+    WHEN json_extract_int(json_data, "$.score") >= 90 THEN 'excellent'
+    WHEN json_extract_int(json_data, "$.score") >= 80 THEN 'good'
+    ELSE 'average'
+END;
+```
+
+### 6.2 JSON数据更新的替代策略
+
+#### 6.2.1 更新策略设计原则
+
+1. **读多写少原则**：JSON主要用于读取密集型场景
+2. **混合存储策略**：频繁更新字段分离存储
+3. **应用层处理**：复杂更新在应用层完成
+4. **版本化管理**：重要数据支持历史版本
+
+#### 6.2.2 具体实施方案
+
+**方案一：JSON完整重构**
+
+```sql
+-- 适用于：简单JSON更新，更新频率低的场景
+UPDATE table_name 
+SET json_column = parse_json(CONCAT(
+    '{"field1": "', json_extract_string(json_column, "$.field1"), '", ',
+    '"field2": "new_value", ',
+    '"field3": ', json_extract_int(json_column, "$.field3"), '}'
+))
+WHERE conditions;
+```
+
+**方案二：混合存储策略**
+
+```sql
+-- 推荐用于：有频繁更新需求的业务场景
+CREATE TABLE IF NOT EXISTS hybrid_table (
+    id INT,
+    frequently_updated_field STRING,  -- 关系型字段
+    status_field INT,                 -- 关系型字段
+    stable_json_data JSON,           -- JSON字段存储稳定数据
+    last_updated TIMESTAMP
+);
+```
+
+**方案三：版本化存储**
+
+```sql
+-- 适用于：需要保留历史版本的重要数据
+CREATE TABLE IF NOT EXISTS versioned_json_data (
+    record_id STRING,
+    version_number INT,
+    json_data JSON,
+    created_time TIMESTAMP,
+    is_current BOOLEAN DEFAULT TRUE
+);
+```
+
+### 6.3 统一语法建议
+
+为了避免混合使用导致的问题，建议统一使用json\_extract函数：
+
+```sql
+-- 创建语法统一演示表
+CREATE TABLE IF NOT EXISTS syntax_demo (
+    order_id STRING,
+    data JSON
+);
+
+-- 插入测试数据
+INSERT INTO syntax_demo VALUES
+('ORD001', parse_json('{"customer": {"id": "C001", "name": "张三", "level": "VIP"}, "payment": {"amount": 1500.00}, "items": [{"qty": 2}]}')),
+('ORD002', parse_json('{"customer": {"id": "C002", "name": "李四", "level": "regular"}, "payment": {"amount": 800.00}, "items": [{"qty": 1}]}')),
+('ORD003', parse_json('{"customer": {"id": "C003", "name": "王五", "level": "VIP"}, "payment": {"amount": 2200.00}, "items": [{"qty": 3}]}'));
+
+-- 推荐的统一语法模式
+SELECT 
+    order_id,
+    json_extract_string(data, "$.customer.id") as customer_id,
+    json_extract_string(data, "$.customer.name") as customer_name,
+    json_extract_string(data, "$.customer.level") as customer_level,
+    json_extract_double(data, "$.payment.amount") as amount,
+    json_extract_int(data, "$.items[0].qty") as quantity
+FROM syntax_demo 
+WHERE json_extract_string(data, "$.customer.level") = 'VIP'
+ORDER BY json_extract_double(data, "$.payment.amount") DESC;
+```
+
+### 6.4 类型安全处理
+
+#### 6.4.1 安全的默认值处理
+
+```sql
+-- 创建类型安全演示表
+CREATE TABLE IF NOT EXISTS type_safety_demo (
+    order_id STRING,
+    order_data JSON
+);
+
+-- 插入包含缺失字段的数据
+INSERT INTO type_safety_demo VALUES
+('ORD001', parse_json('{"customer": {"name": "张三", "vip_level": "gold"}, "payment": {"discount": 100}}')),
+('ORD002', parse_json('{"customer": {"name": "李四"}, "payment": {}}')),  -- 缺少vip_level和discount
+('ORD003', parse_json('{"customer": {"name": "王五", "vip_level": "silver"}, "payment": {"discount": 50}}'));
+
+-- 安全的默认值处理
+SELECT 
+    order_id,
+    json_extract_string(order_data, "$.customer.name") as customer_name,
+    -- 确保类型一致的默认值处理
+    CASE WHEN json_extract_string(order_data, "$.customer.vip_level") IS NOT NULL 
+         THEN json_extract_string(order_data, "$.customer.vip_level") 
+         ELSE 'regular' 
+    END as safe_vip_level,
+    -- 数值类型的安全处理
+    CASE WHEN json_extract_double(order_data, "$.payment.discount") IS NOT NULL 
+         THEN json_extract_double(order_data, "$.payment.discount") 
+         ELSE 0.0 
+    END as safe_discount,
+    -- 使用COALESCE简化默认值处理
+    COALESCE(json_extract_string(order_data, "$.customer.vip_level"), 'regular') as vip_level_coalesce,
+    COALESCE(json_extract_double(order_data, "$.payment.discount"), 0.0) as discount_coalesce
+FROM type_safety_demo;
+```
+
+### 6.5 性能优化策略
+
+#### 6.5.1 高频字段优化
+
+```sql
+-- 创建性能优化演示表
+CREATE TABLE IF NOT EXISTS perf_orders (
+    id INT,

+(4, parse_json('{"customer_id": "C004", "payment_amount": 3200.00, "items": [{"detail": {"description": "奢侈品"}}]}'), CURRENT_DATE());
+
+-- 将常用字段放在JSON顶层，利用自动列式存储优化
+SELECT 
+    json_extract_string(order_data, "$.customer_id") as customer_id,          -- 高频字段
+    json_extract_double(order_data, "$.payment_amount") as amount,            -- 高频字段

+FROM perf_orders 
+WHERE json_extract_string(order_data, "$.customer_id") IS NOT NULL          -- 高效过滤
+  AND json_extract_double(order_data, "$.payment_amount") > 1000;           -- 数值过滤
+```
+
+#### 6.5.2 批量提取优化
+
+```sql
+-- 创建批量优化演示表
+CREATE TABLE IF NOT EXISTS batch_orders (
+    id INT,
+    order_data JSON
+);
+
+-- 插入更多测试数据
+INSERT INTO batch_orders VALUES

+(5, parse_json('{"customer": {"id": "C005", "level": "regular"}, "payment": {"amount": 900.00}}'));
+
+-- 使用CTE减少重复解析
+WITH extracted_data AS (

+## 功能概述
+
+>【**预览发布】本功能当前处于公开预览发布阶段**。
+
+本文主要介绍如何在 SQL 中创建与 Kafka 消息队列系统连接的外部表。通过定义外部表，可以方便地从 Kafka 中读取数据流，并将这些数据流作为表进行查询和分析。
+
+## 创建存储连接
+
+首先，需要创建一个存储连接，用于连接到 Kafka 服务器。目前连接需要证书的方式不支持
+
+### 语法
+
+```SQL
+CREATE STORAGE CONNECTION connection_name
+    TYPE kafka
+    BOOTSTRAP_SERVERS = ['server1:port1', 'server2:port2', ...]
+    SECURITY_PROTOCOL = 'PLAINTEXT';
+```
+
+### 参数说明
+
+* **connection\_name**: 连接的名称，用于后续引用。
+* **TYPE**: 连接类型，此处为 `kafka`。
+* **BOOTSTRAP\_SERVERS**: Kafka 集群的地址列表，格式为 `['host1:port1', 'host2:port2', ...]`。
+* **SECURITY\_PROTOCOL**: 安全协议，可以是 `PLAINTEXT` 等。
+
+### 示例
+
+```SQL
+CREATE STORAGE CONNECTION test_kafka_conn
+    TYPE kafka
+    BOOTSTRAP_SERVERS = ['47.99.48.62:9092']
+    SECURITY_PROTOCOL = 'PLAINTEXT';
+```
+
+## 创建外部表
+
+在创建了存储连接之后，可以定义外部表来读取 Kafka 中的数据。
+
+### 语法
+
+```SQL
+CREATE EXTERNAL TABLE IF NOT EXISTS external_table_name (
+ `topic` string,
+ `partition` int,
+ `offset` bigint,
+ `timestamp` timestamp_ltz,
+ `timestamp_type` string,
+`headers` map<string, string>,
+ `key` binary, `value` binary)
+USING kafka
+CONNECTION connection_name
+OPTIONS (
+    'group_id' = 'consumer_group',
+    'topics' = 'topic_name',
+    'starting_offset' = 'earliest' -- 可选，默认值 earliest
+) ;
+```
+
+### 参数说明
+
+* **external\_table\_name**: 外部表的名称。
+* **字段说明**

+
+## 基础操作
+
+### 1. 运行您的第一个SQL查询
+
+在这个练习中，您将执行简单的SQL查询、创建表并进行基本分析。预计用时：2-3分钟。
+
+1. 登录 Lakehouse Studio
+
+2. 创建一个新的 SQL 工作表，命名为“01_我的第一个SQL”
+
+3. 执行以下SQL命令：
+
+   ```sql
+   -- 使用已创建的虚拟集群和Schema
+   USE VCLUSTER MY_FIRST_VC;
+   USE SCHEMA happy_path;
+
+   -- 简单查询
+   SELECT 1 as id, '你好，Lakehouse！' as greeting;
+   ```
+
+4. 创建一个简单的表并插入数据：
+
+   ```sql
+   -- 创建一个简单的产品表
+   CREATE TABLE IF NOT EXISTS happy_path.my_first_table (
+     product_id INT,
+     product_name STRING,
+     price DECIMAL(10,2),
+     category STRING
+   );
+
+   -- 插入一些示例数据
+   INSERT INTO happy_path.my_first_table VALUES
+     (101, '高清智能电视', 3999.99, '电子产品'),
+     (102, '无线蓝牙耳机', 799.00, '电子产品'),
+     (103, '智能手表', 1299.50, '可穿戴设备'),
+     (104, '便携式充电宝', 159.90, '配件'),
+     (105, '机械键盘', 349.00, '电脑配件');
+     
+   -- 查询刚插入的数据
+   SELECT * FROM happy_path.my_first_table;
+   ```
+
+5. 运行一个聚合查询：
+
+   ```sql
+   -- 按类别统计产品数量和平均价格
+   SELECT 
+     category,
+     COUNT(*) as product_count,
+     AVG(price) as avg_price,
+     MIN(price) as min_price,
+     MAX(price) as max_price
+   FROM happy_path.my_first_table
+   GROUP BY category
+   ORDER BY avg_price DESC;
+   ```
+
+**提示**：您可以看到，无需任何复杂配置，就可以立即执行 SQL 查询、创建表、插入数据和进行分析，这体现了 Lakehouse 简单易用的特性。
+
+### 2. 创建第二个计算集群
+
+接下来，我们来创建一个不同类型的计算集群，了解如何根据不同场景选择合适的计算资源。预计用时：3-6分钟。
+
+1. 创建一个新的 SQL 工作表，命名为“02_创建分析型计算集群”
+
+2. 检查当前环境：
+
+   ```sql
+   -- 确认当前使用的集群和Schema
+   SELECT CURRENT_VCLUSTER();
+   USE SCHEMA happy_path;
+   ```
+
+3. 创建分析型虚拟计算集群：
+
+   ```sql
+   -- 创建分析型虚拟计算集群
+   -- 分析型集群优化了查询性能，适合低延时、高并发的分析场景
+   CREATE VCLUSTER IF NOT EXISTS MY_SECOND_VC 
+   VCLUSTER_SIZE = 1 
+   VCLUSTER_TYPE = ANALYTICS 
+   AUTO_SUSPEND_IN_SECOND = 60 
+   AUTO_RESUME = TRUE 
+   COMMENT '我的第二个虚拟计算集群(分析型)';
+   ```
+
+4. 切换到新创建的集群并测试：
+
+   ```sql
+   -- 使用分析型集群
+   USE VCLUSTER MY_SECOND_VC;
+   USE SCHEMA happy_path;
+
+   -- 创建一个简单的测试表
+   CREATE TABLE IF NOT EXISTS happy_path.simple_test (
+     id INT,
+     name STRING,
+     value DOUBLE
+   );
+
+   -- 插入几行示例数据
+   INSERT INTO happy_path.simple_test VALUES
+     (1, '产品A', 99.5),
+     (2, '产品B', 150.75),
+     (3, '产品C', 25.99);
+
+   -- 查询刚插入的数据
+   SELECT * FROM happy_path.simple_test;
+   ```
+
+5. 查看集群信息：
+
+   ```sql
+   -- 查看当前使用的集群
+   SELECT CURRENT_VCLUSTER();
+
+   -- 查看所有集群
+   SHOW VCLUSTERS;
+   ```
+
+> **💡 提示：集群类型选择**
+> 通用型集群(GENERAL)支持纵向伸缩，满足ETL Pipeline类型的任务需求；分析型集群(ANALYTICS)支持集群内多副本(Replica)的横向伸缩，满足面向并发查询的弹性能力。建议使用通用型集群进行ETL数据加工，使用分析型集群进行查询分析或支持数据产品应用。
+
+## 核心架构体验
+
+### 3. 存算分离架构体验
+
+存算分离是 Lakehouse 的核心架构特性，让您可以灵活调整计算资源而不影响数据存储。预计用时：5-8分钟。
+
+1. 创建一个新的 SQL 工作表，命名为“03_存算分离体验”
+
+2. 准备环境：
+
+   ```sql
+   -- 使用第一个集群(通用型)
+   USE VCLUSTER MY_FIRST_VC;
+   USE SCHEMA happy_path;
+   ```
+
+3. 创建测试数据集：
+
+   ```sql
+   -- 创建一个用于测试的数据集
+   CREATE TABLE IF NOT EXISTS happy_path.demo_dataset (
+     id INT,
+     value DOUBLE,
+     text_data STRING,
+     created_at TIMESTAMP
+   );
+
+   -- 插入一些示例数据
+   INSERT INTO happy_path.demo_dataset VALUES
+     (1, 123.45, 'Text-1', CURRENT_TIMESTAMP()),
+     (2, 678.90, 'Text-2', CURRENT_TIMESTAMP()),
+     (3, 246.80, 'Text-3', CURRENT_TIMESTAMP()),
+     (4, 135.79, 'Text-4', CURRENT_TIMESTAMP()),
+     (5, 975.31, 'Text-5', CURRENT_TIMESTAMP());
+   ```
+
+4. 在第一个集群上查询数据：
+
+   ```sql
+   -- 确认当前使用的集群
+   SELECT CURRENT_VCLUSTER();
+
+   -- 查询数据集
+   SELECT * FROM happy_path.demo_dataset ORDER BY id;
+   ```
+
+5. 切换到第二个集群查询相同数据：
+
+   ```sql
+   -- 切换到第二个集群(分析型)
+   USE VCLUSTER MY_SECOND_VC;
+   USE SCHEMA happy_path;
+
+   -- 查询相同的数据集
+   SELECT * FROM happy_path.demo_dataset ORDER BY id;
+   ```
+
+6. 在第二个集群上添加新数据：
+
+   ```sql
+   -- 在第二个集群上添加新数据
+   INSERT INTO happy_path.demo_dataset VALUES
+     (6, 432.10, 'Text-6', CURRENT_TIMESTAMP()),
+     (7, 789.65, 'Text-7', CURRENT_TIMESTAMP());
+     
+   -- 查询更新后的数据集
+   SELECT * FROM happy_path.demo_dataset ORDER BY id;
+   ```
+
+7. 切换回第一个集群，查看数据变化：
+
+   ```sql
+   -- 切换回第一个集群
+   USE VCLUSTER MY_FIRST_VC;
+   USE SCHEMA happy_path;
+
+   -- 查询数据，验证在另一个集群上添加的数据是否可见
+   SELECT * FROM happy_path.demo_dataset ORDER BY id;
+   ```
+
+> **💡 提示：存算分离架构**
+> Lakehouse采用Single Engine All Data架构，将计算和存储分开，使系统能够更快地处理查询任务。这种架构使计算资源可以根据需求弹性调整，而数据存储在云对象存储中实现"无限扩展"。当不使用集群时，它会自动暂停以节省资源，需要时会自动恢复，有效降低总体拥有成本(TCO)。
+
+### 4. 湖仓一体架构体验
+
+湖仓一体架构允许您用统一的 SQL 直接查询多种格式的文件，无需复杂的 ETL 转换。预计用时：7-10分钟。
+
+1. 创建一个新的 SQL 工作表，命名为“04_湖仓一体体验”
+
+2. 准备环境：
+
+   ```sql
+   -- 使用第一个集群(通用型)，更适合大批量数据导入导出处理
+   USE VCLUSTER MY_FIRST_VC;
+   USE SCHEMA happy_path;
+   ```
+
+3. 创建并准备数据：
+
+   ```sql
+   -- 创建一个产品信息表作为数据源
+   CREATE TABLE IF NOT EXISTS happy_path.products_for_lake (
+     product_id INT,
+     product_name STRING,
+     category STRING,
+     price DECIMAL(10,2),
+     stock_quantity INT,
+     last_update_date DATE
+   );
+
+   -- 插入示例数据
+   INSERT INTO happy_path.products_for_lake VALUES
+     (201, '超薄笔记本电脑', '电脑', 6999.00, 45, DATE '2023-01-15'),
+     (202, '游戏主机', '游戏设备', 3799.00, 30, DATE '2023-01-16'),
+     (203, '无线鼠标', '电脑配件', 129.90, 100, DATE '2023-01-17'),
+     (204, '智能音箱', '智能家居', 599.00, 60, DATE '2023-01-18'),
+     (205, '蓝牙耳机', '音频设备', 899.00, 75, DATE '2023-01-19');
+   ```
+
+4. 导出多种格式的文件到User Volume：
+
+   ```sql

+   SUBDIRECTORY 'lake_demo/sales_csv'
+   FROM happy_path.sales_for_lake
+   FILE_FORMAT = (TYPE = CSV HEADER = TRUE)
+   OVERWRITE = TRUE;
+
+   -- 查看所有导出的文件
+   LIST USER VOLUME SUBDIRECTORY 'lake_demo';
+   ```
+
+6. 使用分析型集群直接查询不同格式文件：
+
+   ```sql
+   -- 切换到分析型集群进行交互式查询
+   USE VCLUSTER MY_SECOND_VC;
+   USE SCHEMA happy_path;
+
+   -- 注意：根据实际导出文件名调整FILES参数
+
+   -- 1. 查询CSV格式文件
+   SELECT * FROM USER VOLUME
+   USING csv
+   OPTIONS('header'='true')
+   FILES('lake_demo/products_csv/part00001.csv')
+   LIMIT 5;
+
+   -- 2. 查询JSON格式文件
+   SELECT * FROM USER VOLUME
+   USING json
+   FILES('lake_demo/products_json/part00001.json')
+   LIMIT 5;
+
+   -- 3. 查询Parquet格式文件
+   SELECT * FROM USER VOLUME
+   USING parquet
+   FILES('lake_demo/products_parquet/part00001.parquet')
+   LIMIT 5;
+   ```
+
+7. 联合查询不同格式的文件：
+
+   ```sql
+   -- 联合查询Parquet格式的产品数据和CSV格式的销售数据
+   SELECT
+      p.product_id,
+      p.product_name,
+      p.category,
+      p.price,
+      s.quantity as quantity_sold,
+      s.total_amount as sales_amount
+   FROM (
+     SELECT * FROM USER VOLUME USING parquet FILES('lake_demo/products_parquet/part00001.parquet')
+   ) p
+   JOIN (
+     SELECT * FROM USER VOLUME USING csv OPTIONS('header'='true') FILES('lake_demo/sales_csv/part00001.csv')
+   ) s ON p.product_id = s.product_id
+   ORDER BY sales_amount DESC;
+   ```
+
+> **注意**：执行上述语句时，请确保文件路径和文件名与实际导出的文件一致。如果文件名不同，请根据`LIST USER VOLUME`命令的结果调整FILES参数中的文件名。

+
+### 5. 离线实时一体化体验
+
+Lakehouse 支持在同一平台上同时处理批处理数据和流处理数据，预计用时：5-7分钟。
+
+1. 创建一个新的 SQL 工作表，命名为“05_离线实时一体体验”
+
+2. 准备环境：
+
+   ```sql
+   -- 使用第二个集群(分析型)，更适合低延时的实时数据查询
+   USE VCLUSTER MY_SECOND_VC;
+   USE SCHEMA happy_path;
+   ```
+
+3. 创建历史订单表和实时订单表：
+
+   ```sql
+   -- 创建历史订单表(代表离线批处理数据)
+   CREATE TABLE IF NOT EXISTS happy_path.historical_orders (
+     order_id STRING,
+     customer_id STRING,
+     product_id STRING,
+     order_amount DECIMAL(10,2),
+     order_time TIMESTAMP,
+     status STRING
+   );
+
+   -- 插入几条历史订单数据
+   INSERT INTO happy_path.historical_orders VALUES
+     ('ORD001', 'CUST001', 'PROD-A', 199.99, TIMESTAMP '2023-01-01 08:30:00', 'COMPLETED'),
+     ('ORD002', 'CUST002', 'PROD-B', 59.95, TIMESTAMP '2023-01-01 09:15:00', 'COMPLETED'),
+     ('ORD003', 'CUST001', 'PROD-C', 149.50, TIMESTAMP '2023-01-02 14:20:00', 'COMPLETED');
+
+   -- 创建实时订单表(代表实时流数据)
+   CREATE TABLE IF NOT EXISTS happy_path.realtime_orders (
+     order_id STRING,
+     customer_id STRING,
+     product_id STRING,
+     order_amount DECIMAL(10,2),
+     order_time TIMESTAMP,
+     status STRING
+   );
+   ```
+
+4. 创建统一视图：
+
+   ```sql
+   -- 创建统一视图查看所有订单
+   CREATE OR REPLACE VIEW happy_path.all_orders AS
+   SELECT order_id, customer_id, product_id, order_amount, order_time, status, 'historical' as data_source
+   FROM happy_path.historical_orders
+   UNION ALL
+   SELECT order_id, customer_id, product_id, order_amount, order_time, status, 'realtime' as data_source
+   FROM happy_path.realtime_orders;
+   ```
+
+5. 查询统一视图：
+
+   ```sql
+   -- 查询所有订单
+   SELECT * FROM happy_path.all_orders ORDER BY order_time DESC;
+
+   -- 查看订单统计
+   SELECT 
+     data_source,
+     COUNT(*) as order_count,
+     SUM(order_amount) as total_amount
+   FROM happy_path.all_orders
+   GROUP BY data_source;
+   ```
+
+6. 模拟实时数据写入：
+
+   ```sql
+   -- 插入新的实时订单
+   INSERT INTO happy_path.realtime_orders VALUES
+     ('ORD004', 'CUST003', 'PROD-B', 59.95, CURRENT_TIMESTAMP(), 'PENDING');
+   ```
+
+7. 再次查询统计结果，查看变化：
+
+   ```sql
+   -- 再次查询订单统计
+   SELECT 
+     data_source,
+     COUNT(*) as order_count,
+     SUM(order_amount) as total_amount
+   FROM happy_path.all_orders
+   GROUP BY data_source;
+   ```
+
+> **💡 提示：离线实时一体架构**
+> Lakehouse支持在同一平台上同时处理批处理数据和流处理数据。通过统一视图，您可以同时查询历史数据和实时数据，当新数据插入后，它立即在统一视图中可见，无需等待批处理窗口或数据同步。这种架构大大简化了需要同时分析历史趋势和实时数据的应用场景。您也可以申请开通“动态表”功能，通过增量计算的实现方式来替代当前视图的方式。
+
+### 6. 向量检索与倒排索引融合检索体验
+
+Lakehouse 支持高效的向量检索和倒排索引检索，可用于实现语义搜索和关键词搜索的混合查询。预计用时：7-10分钟。

+> 在数据处理流程中，可以根据不同的操作类型选择合适的集群类型：通用型集群更适合批量数据处理和转换任务，如 ETL 操作、数据清洗和聚合计算；分析型集群则更适合交互式查询和分析，特别是需要快速响应的仪表盘和报表场景。通过合理分配计算负载，可以优化资源使用并提高整体性能。
+
+## 清理资源
+
+完成体验后，建议清理创建的资源，以避免不必要的资源占用。预计用时：3分钟。
+
+1. 创建一个新的 SQL 工作表，命名为“10_清理环境”
+
+2. 准备环境：
+
+   ```sql
+   -- 使用第一个集群(通用型)
+   USE VCLUSTER MY_FIRST_VC;
+   USE SCHEMA happy_path;
+   ```
+
+3. 清理数据表：
+
+   ```sql
+   -- 列出所有创建的表
+   SHOW TABLES;
+
+   -- 删除创建的表
+   DROP TABLE IF EXISTS happy_path.my_first_table;
+   DROP TABLE IF EXISTS happy_path.simple_test;
+   DROP TABLE IF EXISTS happy_path.demo_dataset;
+   DROP TABLE IF EXISTS happy_path.products_for_lake;
+   DROP TABLE IF EXISTS happy_path.sales_for_lake;
+   DROP TABLE IF EXISTS happy_path.sales_data;
+   DROP TABLE IF EXISTS happy_path.historical_orders;
+   DROP TABLE IF EXISTS happy_path.realtime_orders;
+   DROP TABLE IF EXISTS happy_path.date_dim;
+   DROP TABLE IF EXISTS happy_path.sales_summary;
+   DROP TABLE IF EXISTS happy_path.product_search_demo;
+   ```
+
+4. 清理创建的视图：
+
+   ```sql
+   -- 列出所有创建的视图
+   SHOW TABLES WHERE IS_VIEW=TRUE;
+
+   -- 删除创建的视图
+   DROP VIEW IF EXISTS happy_path.all_orders;
+   DROP VIEW IF EXISTS happy_path.business_insights;
+   ```
+
+5. 清理User Volume中的文件：
+
+   ```sql
+   -- 查看User Volume中的文件
+   LIST USER VOLUME SUBDIRECTORY 'lake_demo';
+
+   -- 删除User Volume中的演示文件
+   REMOVE  USER VOLUME 'lake_demo';
+
+   -- 再次检查确认文件已删除
+   LIST USER VOLUME SUBDIRECTORY 'lake_demo';
+   ```
+
+6. 切换到默认集群：
+
+   ```sql
+   -- 切换到默认集群，确保不在要删除的集群上执行删除操作
+   USE VCLUSTER default;
+   ```
+
+7. 清理虚拟集群：
+
+   ```sql
+   -- 删除之前创建的虚拟集群
+   DROP VCLUSTER IF EXISTS MY_FIRST_VC;
+   DROP VCLUSTER IF EXISTS MY_SECOND_VC;
+   ```
+
+8. 最后清理创建的schema:
+
+   ```sql
+   -- 删除我们创建的happy_path schema
+   DROP SCHEMA IF EXISTS happy_path;
+   ```
+
+> **注意事项**：
+>
+> - 清理前请确认演示体验已全部完成
+> - 如果您打算继续使用某些资源，可以选择性地跳过相应的删除命令
+> - 虚拟集群删除前，必须先切换到另一个集群，否则无法删除当前正在使用的集群
+> - 如果您有重要数据，请在删除前做好备份

+
+## 1. 简介
+
+### 1.1 什么是Table Stream
+
+Table Stream 是云器 Lakehouse 架构中的核心功能，提供变更数据捕获 (CDC) 能力，用于记录表中数据的插入、更新和删除操作。它创建了一个“变更表”，使用户能够查询和消费两个事务时间点之间的行级变更记录。
+
+### 1.2 核心功能
+
+* **变更捕获**：记录表级 DML 操作 (INSERT、UPDATE、DELETE)
+* **元数据记录**：提供每次变更的版本、时间戳等元数据
+* **增量处理**：支持增量读取和处理数据变更
+* **消费机制**：支持通过 DML 操作消费变更数据并移动 offset
+
+### 1.3 适用场景
+
+* 数据同步和复制
+* 实时数据集成
+* 增量 ETL/ELT 流程
+* 审计和数据治理
+* 事件驱动架构
+
+## 2. 准备工作
+
+### 2.1 表配置要求
+
+在使用Table Stream之前，必须确保源表已正确配置：
+
+```sql
+-- 创建源表示例
+CREATE TABLE source_table (
+    id INT,
+    name STRING,
+    value DOUBLE,
+    updated_at TIMESTAMP
+);
+```
+
+### 2.2 开启变更跟踪（必需步骤）
+
+**重要**：必须在源表上开启变更跟踪才能创建 Table Stream：
+
+```sql
+-- 开启变更跟踪
+ALTER TABLE source_table SET PROPERTIES ('change_tracking' = 'true');
+```
+
+这一步是**强制性**的，如果不执行，Table Stream 可能会创建成功但无法正确捕获变更。
+
+### 2.3 准备目标表
+
+如果计划将Stream数据写入目标表，提前创建具有兼容结构的目标表：
+
+```sql
+-- 创建目标表
+CREATE TABLE target_table (
+    id INT,
+    name STRING,
+    value DOUBLE,
+    updated_at TIMESTAMP
+);
+```
+
+## 3. 创建和配置
+
+### 3.1 基本语法
+
+创建Table Stream的基本语法：
+
+```sql
+CREATE TABLE STREAM stream_name 
+ON TABLE source_table
+[COMMENT 'stream description']
+WITH PROPERTIES (
+    'TABLE_STREAM_MODE' = 'STANDARD|APPEND_ONLY',
+    ['SHOW_INITIAL_ROWS' = 'TRUE|FALSE']
+);
+```
+
+### 3.2 重要参数
+
+#### 3.2.1 TABLE\_STREAM\_MODE
+
+* **STANDARD**：捕获所有DML操作(INSERT、UPDATE、DELETE)，反映表的当前状态
+* **APPEND\_ONLY**：只捕获INSERT操作，即使行被更新或删除也保留原始INSERT记录
+
+#### 3.2.2 SHOW\_INITIAL\_ROWS
+
+* **TRUE**：首次消费时返回创建Stream时表中的所有现有行
+* **FALSE**（默认）：首次消费只返回创建Stream后的新变更
+
+### 3.3 时间点设置
+
+可以指定Stream开始捕获变更的时间点：
+
+```sql
+CREATE TABLE STREAM stream_name 
+ON TABLE source_table
+TIMESTAMP AS OF current_timestamp()
+WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
+```
+
+**最佳实践**：使用 `current_timestamp()` 或具体的时间戳字符串，避免使用复杂的时间表达式。
+
+### 3.4 注释添加
+
+为Stream添加描述性注释：
+
+```sql
+CREATE TABLE STREAM stream_name 
+ON TABLE source_table
+COMMENT '捕获source_table的数据变更'
+WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
+```
+
+**注意**：使用正确的语法 `COMMENT '注释内容'`，而非 `COMMENT = '注释内容'`。
+
+## 4. 使用不同模式
+
+### 4.1 STANDARD模式
+
+**推荐用途**：需要表的完整当前状态，包括更新和删除操作。
+
+```sql
+CREATE TABLE STREAM standard_stream 
+ON TABLE source_table
+WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
+```
+
+特点：
+
+* 准确反映表的当前状态
+* 更新会显示最新值
+* 已删除的行不会出现在结果中
+
+### 4.2 APPEND\_ONLY模式
+
+**推荐用途**：需要保留所有插入记录，包括后续被更新或删除的记录。
+
+```sql
+CREATE TABLE STREAM append_stream 
+ON TABLE source_table
+WITH PROPERTIES ('TABLE_STREAM_MODE' = 'APPEND_ONLY');
+```
+
+特点：
+
+* 记录所有INSERT操作
+* 不反映UPDATE和DELETE操作
+* 即使行被删除，原始INSERT记录仍会保留
+
+### 4.3 模式选择指南
+
+| 需求             | 推荐模式         |
+| -------------- | ------------ |
+| 数据同步（保持目标与源一致） | STANDARD     |
+| 审计所有插入记录       | APPEND\_ONLY |
+| 增量ETL流程        | STANDARD     |
+| 历史记录保留         | APPEND\_ONLY |
+
+## 5. 消费和处理数据
+
+### 5.1 查询Stream数据
+
+```sql
+-- 查询Stream中的变更数据
+SELECT * FROM my_stream;
+```
+
+**重要**：仅使用 SELECT 查询不会移动 Stream 的 offset。
+
+### 5.2 消费和移动Offset
+
+要移动 Stream 的 offset（消费数据），必须使用 DML 操作：
+
+```sql
+-- 将Stream数据插入目标表（会移动offset）
+INSERT INTO target_table
+SELECT id, name, value, updated_at 
+FROM my_stream;
+```
+
+### 5.3 消费模式
+
+#### 5.3.1 全量消费
+
+```sql
+-- 消费Stream中的所有变更数据
+INSERT INTO target_table
+SELECT id, name, value, updated_at 
+FROM my_stream;
+```
+
+#### 5.3.2 条件消费
+
+```sql
+-- 仅消费特定条件的变更数据
+INSERT INTO target_table
+SELECT id, name, value, updated_at 
+FROM my_stream
+WHERE value > 100;
+```
+
+**注意**：即使使用 WHERE 条件，所有 Stream 数据的 offset 仍会移动。
+
+### 5.4 验证消费状态
+
+通过再次查询Stream，验证数据是否被消费：
+
+```sql
+-- 验证消费后的Stream状态
+SELECT COUNT(*) FROM my_stream;
+```
+
+如果消费成功，COUNT应该为0或只包含新的变更数据。
+
+## 6. 元数据字段使用
+
+### 6.1 可用元数据字段
+
+Table Stream返回的结果包含以下元数据字段：
+
+* `__change_type`：变更类型
+* `__commit_version`：提交版本
+* `__commit_timestamp`：提交时间戳
+
+### 6.2 变更类型判断
+
+**注意**：根据我们的测试，`__change_type` 字段的实际行为可能与文档描述不一致。所有记录都标记为“INSERT”，即使是更新或删除操作。
+
+因此，建议通过以下方式判断变更类型：
+
+1. **INSERT操作**：新记录出现在Stream中
+2. **UPDATE操作**：同一ID记录的`__commit_version`字段值增加
+3. **DELETE操作**：记录不再出现在 STANDARD 模式的结果中
+
+### 6.3 使用元数据实现增量处理
+
+```sql
+-- 基于提交版本筛选
+SELECT * FROM my_stream
+WHERE __commit_version > last_processed_version;
+
+-- 基于提交时间筛选
+SELECT * FROM my_stream
+WHERE __commit_timestamp > TIMESTAMP '2025-05-01 00:00:00';
+```
+
+### 6.4 元数据字段最佳实践
+
+* 不要依赖 `__change_type` 字段区分操作类型
+* 使用 `__commit_version` 和 `__commit_timestamp` 跟踪变更
+* 关注数据的最终状态而非变更过程
+* 保存消费的最大版本号，用于故障恢复
+
+## 7. 实际应用场景
+
+### 7.1 实时数据同步
+
+```sql
+-- 定期执行，将变更同步到目标表
+INSERT INTO target_table
+SELECT id, name, value, updated_at 
+FROM source_stream;
+```
+
+可结合定时任务或触发器实现自动同步。
+
+### 7.2 增量ETL流程
+
+```sql
+-- 增量提取、转换并加载数据
+INSERT INTO dwh_fact_table (dimension_id, metric_value, load_date)
+SELECT 
+    dim.dimension_id,
+    stream.value,
+    current_date()
+FROM source_stream stream
+JOIN dimension_table dim ON stream.id = dim.source_id;
+```
+
+### 7.3 事件驱动处理
+
+```sql
+-- 检测特定事件并触发处理
+CREATE OR REPLACE PROCEDURE process_high_value_changes() AS
+BEGIN
+    -- 检查是否有高价值变更
+    DECLARE high_value_changes CURSOR FOR 
+        SELECT * FROM value_stream WHERE value > 1000;
+    
+    -- 处理这些变更
+    FOR change IN high_value_changes DO
+        -- 执行处理逻辑
+        INSERT INTO high_value_alerts VALUES (change.id, change.value, current_timestamp());
+    END FOR;
+    
+    -- 消费所有变更
+    INSERT INTO processed_changes
+    SELECT * FROM value_stream;
+END;
+```
+
+### 7.4 审计跟踪
+
+```sql
+-- 捕获所有变更用于审计
+CREATE TABLE STREAM audit_stream 
+ON TABLE sensitive_data
+WITH PROPERTIES (
+    'TABLE_STREAM_MODE' = 'APPEND_ONLY',
+    'SHOW_INITIAL_ROWS' = 'TRUE'
+);
+
+-- 定期归档到审计表
+INSERT INTO audit_history
+SELECT 
+    *,
+    __commit_timestamp AS audit_timestamp,
+    __commit_version AS change_version
+FROM audit_stream;
+```
+
+## 8. 性能优化
+
+### 8.1 减少数据体积
+
+* 只选择必要的列而非 `SELECT *`
+* 在源表上设置适当的保留期
+* 定期消费Stream数据以避免累积
+
+### 8.2 批量处理
+
+```sql
+-- 批量消费多个Stream并合并处理
+INSERT INTO consolidated_target
+SELECT 'customers' AS source, id, name, NULL AS product_id, NULL AS order_id, __commit_timestamp
+FROM customer_stream
+UNION ALL
+SELECT 'products' AS source, id, name, product_id, NULL AS order_id, __commit_timestamp
+FROM product_stream
+UNION ALL
+SELECT 'orders' AS source, id, NULL AS name, NULL AS product_id, order_id, __commit_timestamp
+FROM order_stream;
+```
+
+### 8.3 并行处理
+
+将大型Stream拆分为多个较小的部分并行处理：
+
+```sql
+-- 分区1处理
+INSERT INTO target_partition_1
+SELECT * FROM source_stream WHERE MOD(id, 4) = 0;
+
+-- 分区2处理
+INSERT INTO target_partition_2
+SELECT * FROM source_stream WHERE MOD(id, 4) = 1;
+
+-- 以此类推...
+```
+
+### 8.4 频率优化
+
+* 高变更率表：更频繁地消费Stream
+* 低变更率表：降低消费频率
+* 关键表：实时或近实时消费
+* 非关键表：批量定期消费
+
+## 9. 常见问题和解决方案
+
+### 9.1 Stream不捕获变更
+
+**问题**：创建 Stream 后未能捕获表变更。
+
+**解决方案**：
+
+1. 确认已开启变更跟踪：`ALTER TABLE table_name SET PROPERTIES ('change_tracking' = 'true')`
+2. 验证是否有足够权限
+3. 确认 DML 操作在 Stream 创建后执行
+
+### 9.2 无法区分变更类型
+
+**问题**：所有变更都标记为INSERT，无法区分更新和删除。
+
+**解决方案**：
+
+1. 使用 `__commit_version` 变化判断更新
+2. 记录之前的状态并与当前比较
+3. 对于STANDARD模式，通过记录是否存在来判断删除
+
+### 9.3 重复消费数据
+
+**问题**：重复运行消费逻辑导致目标表出现重复数据。
+
+**解决方案**：
+
+1. 使用MERGE语句替代INSERT
+2. 实现幂等性处理
+3. 记录最后消费的版本和时间戳
+
+```sql
+-- 幂等消费示例
+MERGE INTO target_table t
+USING my_stream s
+ON t.id = s.id
+WHEN MATCHED THEN
+    UPDATE SET 
+        t.name = s.name,
+        t.value = s.value,
+        t.updated_at = s.updated_at
+WHEN NOT MATCHED THEN
+    INSERT (id, name, value, updated_at)
+    VALUES (s.id, s.name, s.value, s.updated_at);
+```
+
+### 9.4 消费后未移动Offset
+
+**问题**：消费后再次查询仍返回相同数据。
+
+**解决方案**：
+
+1. 确保使用 DML 操作消费数据（INSERT、UPDATE、MERGE）
+2. 不要仅使用 SELECT 查询，这不会移动 offset
+3. 检查 DML 操作是否成功提交
+
+## 10. 最佳实践总结
+
+### 10.1 设计原则
+
+1. **始终开启变更跟踪**：在创建Stream前开启表的变更跟踪
+2. **选择合适的模式**：根据需求选择STANDARD或APPEND\_ONLY模式
+3. **定期消费**：不要让Stream累积过多数据
+4. **关注最终状态**：重点关注数据的最终状态而非变更过程
+5. **不依赖变更类型**：不要依赖 `__change_type` 字段区分操作类型
+
+### 10.2 使用清单
+
+* [ ] 在源表上开启change\_tracking
+* [ ] 选择合适的Stream模式
+* [ ] 考虑是否需要SHOW\_INITIAL\_ROWS
+* [ ] 使用DML操作消费数据
+* [ ] 实现幂等性消费机制
+* [ ] 监控Stream大小和性能
+* [ ] 记录消费的版本和时间戳
+* [ ] 实现错误处理和重试逻辑
+
+### 10.3 成功实现的关键
+
+* **理解机制**：掌握Stream的工作原理和限制
+* **适当测试**：在生产环境部署前充分测试
+* **定期维护**：监控和优化Stream性能
+* **记录状态**：跟踪消费状态，确保数据一致性
+* **容错设计**：考虑故障恢复和边缘情况
+
+遵循这些最佳实践，您将能够充分利用云器Lakehouse Table Stream功能，构建高效可靠的数据变更捕获和处理流程。

+# 云器Lakehouse费用异常告警配置指南
+
+## 概述
+
+本指南帮助您快速配置费用异常监控系统，实现费用突增时的自动告警，保障您的成本安全。
+
+## 前置条件
+
+* 拥有 instance_admin 角色权限，用于查询 sys.information_schema.instance_usage 视图中的费用数据。
+* 拥有 instance_sre 角色权限，用于使用“数据质量”和“监控告警”功能。
+* 具备某一工作空间内计算集群的使用权限（用于执行质量规则查询 SQL）和某一表或视图的元数据查询（read metadata）权限（用于配置质量规则）。
+
+## 使用数据
+
+sys.information_schema.instance_usage 视图的字段和内容介绍可见于文末附录。
+
+## 配置步骤
+
+### 步骤1：创建数据质量规则
+
+1\. 进入**数据质量管理**模块
+
+2\. 点击**创建质量规则**
+
+:-: ![](.topwrite/assets/image_1760009305873.png =804)
+
+^
+
+3\. 填写基本信息：
+
+:-:
+![](.topwrite/assets/image_1760009346751.png =793)
+
+在本案例中主要关注以下三个选项：
+1) 校验方式：选择“自定义 SQL”；
+2) 根据本文建议的规则，直接将 SQL 粘贴到文本框中；
+3) 在“期待结果”中，根据所选择的规则配置对应的预期条件和值。
+
+其他字段配置可详见数据质量的完整配置文档：[数据质量](https://www.yunqi.tech/documents/DataQuality)
+
+### 步骤2：配置监控告警
+
+1\. 进入**监控告警**模块，点击“**新建规则**”
+
+:-: ![](.topwrite/assets/image_1760009359793.png =776)
+
+2\. 配置告警规则
+
+在本案例中主要关注以下3个选项：
+
+1) 监控事项：选择 **数据质量监控失败** 告警，并 **添加过滤条件**，以有效过滤掉其他质量规则，避免因其他质量规则校验失败而产生的干扰。
+
+2) 通知策略：根据实际需要选择所需的通知策略，也可单独新建一条通知策略。通知策略的相关配置可参考文档：[监控告警系统](https://www.yunqi.tech/documents/monitoring_and_alerting)。
+
+3) 通知人员：选择关注费用的相关人员。可以通过在账户中心新建用户，将需要通知的用户添加到此列表中。
+
+:-: ![](.topwrite/assets/image_1760009490281.png =640)
+
+完成上述两步配置，即完成了从监控到告警的完整流程。当质量规则监控到异常时，您将通过对应渠道收到告警信息。
+
+下面具体说明在数据质量规则中，可供选择的监控规则。
+
+## 监控方案
+
+### 方案一：固定阈值监控（简单快速）
+
+**适用场景**：费用相对稳定，有明确的预算上限。
+
+**监控SQL**：
+
+```SQL
+-- 查询昨日总费用
+SELECT
+  ROUND(SUM(COALESCE(total_after_discount, amount * discount_rate)), 2) AS total_amount
+FROM sys.information_schema.instance_usage
+WHERE CAST(SUBSTR(measurement_start, 1, 10) AS DATE) = current_date() - INTERVAL 1 DAY
+```
+
+**告警配置**：
+* 预期结果 ≤ 50（根据实际调整阈值）
+* 超过阈值则触发告警
+
+**阈值参考查询**：
+
+```SQL
+-- 查询过去90天的费用参考值
+WITH day_sum AS (
+  SELECT
+    CAST(SUBSTR(measurement_start, 1, 10) AS DATE) AS bill_date,
+    SUM(COALESCE(total_after_discount, amount * discount_rate)) AS day_amount
+  FROM sys.information_schema.instance_usage
+  WHERE CAST(SUBSTR(measurement_start, 1, 10) AS DATE) BETWEEN 
+    date_sub(current_date(), 90) AND current_date() - INTERVAL 1 DAY
+  GROUP BY 1
+)
+SELECT
+  ROUND(MAX(day_amount), 2) AS max_daily,      -- 历史最高
+  ROUND(AVG(day_amount), 2) AS avg_daily,      -- 平均值
+  ROUND(percentile_approx(day_amount, 0.95), 2) AS p95_daily  -- 95分位
+FROM day_sum
+```
+
+### 方案二：动态基线监控（关注异常波动）
+
+**适用场景**：费用存在稳定的上升或下降趋势，需要关注费用波动而非绝对值。
+
+**监控SQL**：
+
+```SQL

+```
+
+## 监控效果验证
+
+1. **手动测试**：配置质量规则后，可进行试跑，以验证质量规则配置和 SQL 的正确性。
+2. **告警测试**：在试跑测试时，可（手动）触发告警以验证通知功能，从而确认通知策略配置正确。
+3. **历史回溯**：查看过去 7 天的费用数据，确认阈值的合理性。
+
+通过以上步骤，您可以快速搭建费用异常告警系统，有效控制成本风险。

+
+***
+
+## 📊 数据类型设计策略
+
+### 数值类型选择指南
+
+#### 自增主键设计
+
+**关键限制**: IDENTITY列仅支持BIGINT类型
+
+```sql
+-- 正确的IDENTITY使用(唯一支持的语法)
+CREATE TABLE business_events (
+    event_id BIGINT IDENTITY,              -- 仅支持BIGINT类型
+    event_data JSON,
+    created_at TIMESTAMP DEFAULT current_timestamp()
+);
+
+-- 带种子值的IDENTITY
+CREATE TABLE user_accounts (
+    user_id BIGINT IDENTITY(1000),         -- 从1000开始自增
+    username VARCHAR(50) NOT NULL
+);
+```
+
+**不支持的IDENTITY语法(测试确认会失败**):
+
+```sql
+-- 这些都会导致错误：invalid identity column type int, currently only BIGINT is supported
+CREATE TABLE wrong_examples (
+    id INT IDENTITY,                       -- 失败
+    small_id SMALLINT IDENTITY,            -- 失败  
+    str_id VARCHAR(50) IDENTITY            -- 失败
+);
+```
+
+#### 业务数值字段选择
+
+| 数据类型           | 存储空间 | 数值范围             | 推荐场景     | 实际应用示例                     |
+| -------------- | ---- | ---------------- | -------- | -------------------------- |
+| `TINYINT`      | 1字节  | -128 到 127       | 状态码、等级   | `status TINYINT DEFAULT 1` |
+| `SMALLINT`     | 2字节  | -32,768 到 32,767 | 年份、计数器   | `birth_year SMALLINT`      |
+| `INT`          | 4字节  | ±21亿             | 业务ID、大计数 | `user_id INT NOT NULL`     |
+| `BIGINT`       | 8字节  | ±922万万亿          | 自增主键、大数值 | `id BIGINT IDENTITY`       |
+| `DECIMAL(p,s)` | 变长   | 最高精度38位          | 金融计算     | `amount DECIMAL(15,2)`     |
+| `FLOAT`        | 4字节  | 单精度浮点            | 科学计算、坐标  | `temperature FLOAT`        |
+| `DOUBLE`       | 8字节  | 双精度浮点            | 高精度计算    | `coordinate DOUBLE`        |
+
+### 字符串类型策略
+
+#### 长度规划原则（基于实际业务需求）
+
+| 业务场景  | 推荐类型            | 长度设置      | 实际覆盖率 | 设计考量              |
+| ----- | --------------- | --------- | ----- | ----------------- |
+| 邮箱地址  | `VARCHAR(320)`  | RFC5321标准 | 99.9% | 国际标准长度            |
+| 用户名   | `VARCHAR(50)`   | 实际调研      | 99.5% | 平衡存储和使用           |
+| 手机号   | `VARCHAR(20)`   | 国际格式      | 100%  | 支持+86-138\*\*\*\* |
+| URL地址 | `VARCHAR(2048)` | 实际测量      | 98%   | 含复杂查询参数           |
+| 文章标题  | `VARCHAR(200)`  | SEO优化     | 95%   | 搜索引擎友好            |
+| 商品描述  | `VARCHAR(2000)` | 电商需求      | 90%   | 详情页展示             |
+| 长文本内容 | `STRING`        | 不限长度      | 100%  | 博客、评论等            |
+
+```sql
+-- 字符串类型最佳实践
+CREATE TABLE user_profiles (
+    user_id BIGINT IDENTITY,
+    
+    -- 固定格式使用CHAR
+    country_code CHAR(2),                   -- CN, US, JP
+    currency_code CHAR(3),                  -- USD, CNY, EUR
+    
+    -- 业务字段使用合理的VARCHAR长度
+    username VARCHAR(50) NOT NULL,
+    email VARCHAR(320) NOT NULL,
+    mobile_phone VARCHAR(20),
+    
+    -- 描述性内容
+    nickname VARCHAR(100),
+    bio VARCHAR(500),                       -- 个人简介
+    full_description STRING,                -- 详细描述，长度不定
+    
+    -- 结构化数据
+    preferences JSON DEFAULT '{}'
+);
+```
+
+### 向量类型应用场景
+
+#### 向量类型语法和应用
+
+**标准语法**: `VECTOR(scalar_type, dimension)` 或 `VECTOR(dimension)`
+
+| 标量类型      | 存储开销  | 适用场景      | 维度推荐     | 应用示例                   |
+| --------- | ----- | --------- | -------- | ---------------------- |
+| `FLOAT`   | 4字节/维 | 语义向量、通用AI | 128-2048 | `VECTOR(FLOAT, 768)`   |
+| `INT`     | 4字节/维 | 离散特征、计数向量 | 64-1024  | `VECTOR(INT, 256)`     |
+| `TINYINT` | 1字节/维 | 压缩向量、移动端  | 64-512   | `VECTOR(TINYINT, 128)` |
+
+**实际应用案例**:
+
+```sql
+CREATE TABLE ai_content_vectors (
+    content_id BIGINT IDENTITY,
+    content_type VARCHAR(50),
+    
+    -- 不同业务场景的向量配置
+    text_embedding VECTOR(FLOAT, 768),      -- BERT/RoBERTa输出
+    image_features VECTOR(FLOAT, 512),      -- ResNet/CNN特征
+    user_preference VECTOR(INT, 256),       -- 推荐系统用户画像
+    mobile_compact VECTOR(TINYINT, 128),    -- 移动端轻量化
+    general_vector VECTOR(512)              -- 默认FLOAT类型
+);
+
+-- 向量数据插入语法（注意：维度必须严格匹配）
+INSERT INTO ai_content_vectors (content_type, text_embedding) VALUES (
+    'document',
+    cast(concat('[', repeat('0.1,', 767), '0.1]') as VECTOR(FLOAT, 768))
+);
+```
+
+### 复杂数据类型使用指南
+
+#### STRUCT类型正确使用
+
+**正确的STRUCT数据插入语法**:
+
+```sql
+CREATE TABLE user_complex_data (
+    user_id BIGINT IDENTITY,
+    
+    -- 简单结构体
+    basic_info STRUCT<id:INT, name:STRING, age:INT>,
+    
+    -- 复杂嵌套结构体  
+    detailed_profile STRUCT<
+        personal:STRUCT<name:STRING, email:STRING>,
+        address:STRUCT<city:STRING, country:STRING>,
+        preferences:MAP<STRING, STRING>
+    >
+);
+
+-- 方法1：使用struct函数（按位置传参）
+INSERT INTO user_complex_data (basic_info) VALUES (
+    struct(123, 'Alice', 25)
+);
+
+-- 方法2：使用named_struct函数（推荐，明确字段名）
+INSERT INTO user_complex_data (basic_info) VALUES (
+    named_struct('id', 123, 'name', 'Alice', 'age', 25)
+);
+
+-- 复杂嵌套结构的插入
+INSERT INTO user_complex_data (detailed_profile) VALUES (
+    named_struct(
+        'personal', named_struct('name', 'Bob', 'email', 'bob@test.com'),
+        'address', named_struct('city', 'Shanghai', 'country', 'China'),
+        'preferences', map('lang', 'zh', 'theme', 'dark')
+    )
+);
+```
+
+#### ARRAY和MAP类型使用
+
+```sql
+CREATE TABLE collection_types_demo (
+    record_id BIGINT IDENTITY,
+    
+    -- 数组类型
+    tags ARRAY<STRING>,
+    scores ARRAY<INT>,
+    nested_arrays ARRAY<ARRAY<STRING>>,
+    
+    -- 映射类型
+    config MAP<STRING, STRING>,
+    metrics MAP<STRING, DOUBLE>,
+    complex_map MAP<STRING, ARRAY<INT>>
+);
+
+-- 正确的插入语法
+INSERT INTO collection_types_demo (
+    tags, scores, nested_arrays, config, metrics, complex_map
+) VALUES (
+    array('tech', 'AI', 'database'),                    -- 字符串数组
+    array(85, 92, 78),                                  -- 整数数组
+    array(array('group1', 'item1'), array('group2', 'item2')), -- 嵌套数组
+    map('env', 'prod', 'version', 'v2.2'),             -- 字符串映射
+    map('cpu_usage', 0.75, 'memory_usage', 0.60),      -- 数值映射
+    map('feature1', array(1, 2, 3), 'feature2', array(4, 5, 6)) -- 复杂映射
+);
+```
+
+***
+
+## 🏗️ 表结构设计模式
+
+### 约束设计策略
+
+#### NOT NULL约束的合理应用
+
+NOT NULL约束不仅保障数据完整性，更是查询优化器的重要提示:
+
+```sql
+CREATE TABLE order_management (
+    order_id BIGINT IDENTITY,
+    
+    -- 业务核心字段：必须非空
+    customer_id INT NOT NULL,               -- 核心业务关联
+    order_time TIMESTAMP NOT NULL,         -- 核心时间维度
+    order_status TINYINT NOT NULL DEFAULT 0, -- 业务状态
+    total_amount DECIMAL(12,2) NOT NULL,    -- 核心金额字段
+    
+    -- 可选业务字段：允许为空
+    coupon_code VARCHAR(20),               -- 优惠券（可选）
+    customer_notes VARCHAR(500),           -- 客户备注（可选）
+    gift_message VARCHAR(200),             -- 礼品留言（可选）
+    
+    -- 系统字段：非空且有默认值
+    created_at TIMESTAMP NOT NULL DEFAULT current_timestamp(),
+    updated_at TIMESTAMP,                  -- 更新时间（首次为NULL）
+    
+    -- 分区字段（生成列）
+    date_partition STRING GENERATED ALWAYS AS (
+        date_format(order_time, 'yyyy-MM-dd')
+    )
+) 
+PARTITIONED BY (date_partition);
+```
+
+#### 默认值的使用
+
+默认值设计应当反映业务逻辑和系统行为:
+
+```sql
+CREATE TABLE user_account_enhanced (
+    user_id BIGINT IDENTITY,
+    username VARCHAR(50) NOT NULL,
+    
+    -- 业务状态的合理默认值
+    account_status TINYINT DEFAULT 1,      -- 1=正常, 0=禁用, 2=锁定
+    email_verified BOOLEAN DEFAULT false,  -- 默认未验证
+    phone_verified BOOLEAN DEFAULT false,  -- 默认未验证
+    
+    -- 数值字段的业务默认值
+    credit_balance DECIMAL(10,2) DEFAULT 0.00,  -- 默认余额为0
+    loyalty_points INT DEFAULT 0,               -- 默认积分为0
+    login_attempts TINYINT DEFAULT 0,           -- 默认登录尝试次数
+    
+    -- 时间字段的系统默认值
+    registration_time TIMESTAMP DEFAULT current_timestamp(),
+    last_login_time TIMESTAMP,             -- 首次登录前为NULL
+    password_changed_at TIMESTAMP DEFAULT current_timestamp(),
+    
+    -- JSON字段的默认值
+    user_preferences JSON DEFAULT '{}',    -- 默认空对象
+    security_settings JSON DEFAULT '{"two_factor": false, "login_notifications": true}'
+);
+```
+

+
+#### 时间序列分区模式
+
+**模式1: 按日分区（推荐，最常用**）
+
+```sql
+CREATE TABLE daily_business_logs (
+    log_id BIGINT IDENTITY,
+    application VARCHAR(50) NOT NULL,
+    log_level VARCHAR(10) NOT NULL,

+
+**模式2: 按小时分区（高频数据**）
+
+```sql

+COMMENT '实时指标表 - 按小时分区，支持高频数据写入';
+```
+
+**模式3: 按月分区（历史归档**）
+
+```sql
+CREATE TABLE monthly_report_data (

+    )
+) 
+PARTITIONED BY (month_partition)
+COMMENT '月度报表数据 - 按月分区，优化长期存储';
+```
+
+#### 业务维度分区模式
+
+**多租户分区模式**:
+
+```sql
+CREATE TABLE saas_tenant_data (
+    record_id BIGINT IDENTITY,
+    tenant_id VARCHAR(50) NOT NULL,
+    entity_type VARCHAR(50) NOT NULL,

+
+**地理区域分区模式**:
+
+```sql

+
+#### 复合分区策略（高级应用）
+
+**时间+业务维度双重分区**:
+
+```sql
+CREATE TABLE advanced_partitioning_example (

+SORTED BY (event_time DESC)
+INTO 256 BUCKETS
+COMMENT '高级分区示例 - 时间和业务维度双重分区';
+```
+
+### 分区管理和优化
+
+#### 动态分区限制
+
+**关键限制**: 单个插入任务最多创建2048个动态分区
+
+```sql
+-- 可能超出限制的操作
+INSERT INTO large_partition_table 
+SELECT * FROM source_table_with_many_partitions;  -- 如果source表分区数>2048会失败
+
+-- 解决方案1: 分批插入
+INSERT INTO large_partition_table 
+SELECT * FROM source_table_with_many_partitions 
+WHERE date_column BETWEEN '2024-01-01' AND '2024-01-10';  -- 限制分区范围
+
+-- 解决方案2: 循环插入（应用层实现）
+-- 在应用程序中按日期/区域等维度分批插入，每批控制在2000个分区以内
+```
+
+#### 数据生命周期管理
+
+```sql
+-- 设置表级数据生命周期
+CREATE TABLE lifecycle_managed_table (
+    record_id BIGINT IDENTITY,
+    business_data JSON,
+    created_time TIMESTAMP,
+

+## 🪣 分桶与排序优化
+
+### 分桶策略设计
+
+#### 分桶数量规划指南
+
+基于实际测试验证的分桶配置建议:
+
+| 数据规模     | 建议桶数     | 单桶目标大小  | 适用场景      | 测试验证结果 |
+| -------- | -------- | ------- | --------- | ------ |
+| < 10GB   | 16-32    | \~512MB | 小型业务表、维度表 | 测试通过   |
+| 10GB-1TB | 64-256   | \~1GB   | 主要业务表、事实表 | 测试通过   |
+| 1TB-10TB | 256-1024 | \~2GB   | 大型分析表、历史表 | 推荐配置   |
+| > 10TB   | 1024+    | \~4GB   | 超大数据仓库表   | 架构支持   |
+
+#### 分桶列选择原则
+
+1. **高基数原则**: 选择值分布均匀、基数高的列
+2. **查询亲和性**: 优先选择JOIN和GROUP BY中的关键列
+3. **写入均衡**: 避免数据倾斜和写入热点
+
+```sql
+-- 最佳实践：用户行为分析表
+CREATE TABLE user_behavior_optimized (
+    behavior_id BIGINT IDENTITY,
+    user_id INT NOT NULL,                   -- 高基数，分布均匀
+    session_id VARCHAR(100) NOT NULL,
+    behavior_type VARCHAR(50),              -- 浏览、点击、购买等
+    behavior_time TIMESTAMP NOT NULL,
+    product_id INT,
+    
+    -- 分区策略
+    date_partition STRING GENERATED ALWAYS AS (date_format(behavior_time, 'yyyy-MM-dd'))
+) 
+PARTITIONED BY (date_partition)
+HASH CLUSTERED BY (user_id)               -- 用户维度分桶，支持用户行为分析
+SORTED BY (behavior_time DESC, behavior_type ASC)  -- 时间倒序+行为类型排序  
+INTO 256 BUCKETS;                         -- 适合中大型数据量
+
+-- 索引优化
+CREATE BLOOMFILTER INDEX user_lookup_idx ON TABLE user_behavior_optimized(user_id);
+CREATE BLOOMFILTER INDEX product_filter_idx ON TABLE user_behavior_optimized(product_id);
+CREATE INVERTED INDEX behavior_type_idx ON TABLE user_behavior_optimized(behavior_type);
+```
+
+### 排序策略优化
+
+排序字段的选择直接影响查询性能，特别是范围查询和TOP-N查询:
+
+```sql
+-- 金融交易表的排序优化
+CREATE TABLE financial_transactions_optimized (
+    transaction_id BIGINT IDENTITY,
+    account_id INT NOT NULL,
+    transaction_time TIMESTAMP NOT NULL,

+) 
+PARTITIONED BY (date_partition)
+HASH CLUSTERED BY (account_id)            -- 按账户分桶
+SORTED BY (
+    transaction_time DESC,                 -- 时间倒序：最新交易优先
+    amount DESC,                           -- 金额倒序：大额交易优先

+
+#### 适用场景分析
+
+| 使用场景    | 基数特征      | 查询模式    | 优化效果  | 实际应用    |
+| ------- | --------- | ------- | ----- | ------- |
+| 用户ID查找  | 极高基数(百万+) | = 精确匹配  | 显著提升  | 用户行为分析  |
+| 邮箱地址验证  | 高基数，唯一性强  | = 存在性检查 | 快速过滤  | 注册去重验证  |

+| 设备ID监控  | 高基数，设备唯一  | = 设备状态  | 高效过滤  | IoT监控平台 |
+
+#### 布隆过滤器最佳实践
+
+```sql
+-- 高基数用户管理表
+CREATE TABLE user_management_optimized (
+    user_id BIGINT IDENTITY,
+    username VARCHAR(50) NOT NULL,
+    email VARCHAR(320) NOT NULL,

+
+CREATE BLOOMFILTER INDEX phone_bloom_idx

+FROM user_management_optimized 
+WHERE device_fingerprint = 'specific_device_fp'  -- 布隆过滤器快速匹配
+GROUP BY user_id;
+```
+
+### 索引命名和管理规范
+
+#### 索引命名最佳实践
+
+**重要更新**: 经过实际测试验证，当前版本的云器Lakehouse在索引命名方面**严格强制schema级唯一性**。
+
+#### 推荐的索引命名规范
+
+**命名格式**: `{table_name}_{index_type}_{column_name}_idx`
+
+**索引类型缩写**:
+
+* `vec` - 向量索引 (VECTOR INDEX)
+* `inv` - 倒排索引 (INVERTED INDEX)
+* `bloom` - 布隆过滤器索引 (BLOOMFILTER INDEX)
+
+```sql
+-- 正确的索引命名实践
+CREATE TABLE product_catalog (
+    product_id INT,
+    product_name VARCHAR(200),
+    description STRING,
+    category VARCHAR(100),
+    price DECIMAL(10,2),
+    features_vector VECTOR(FLOAT, 512)
+);
+
+-- 唯一且描述性的索引名称
+CREATE VECTOR INDEX products_vec_features_idx 
+ON TABLE product_catalog(features_vector)
+PROPERTIES ("distance.function" = "cosine_distance");
+
+CREATE INVERTED INDEX products_inv_name_idx 
+ON TABLE product_catalog(product_name)
+PROPERTIES ('analyzer' = 'chinese');
+
+CREATE INVERTED INDEX products_inv_desc_idx 
+ON TABLE product_catalog(description)
+PROPERTIES ('analyzer' = 'unicode');
+
+CREATE BLOOMFILTER INDEX products_bloom_category_idx 
+ON TABLE product_catalog(category);
+
+-- 另一个表使用不同的索引名称前缀
+CREATE TABLE user_content (
+    content_id BIGINT IDENTITY,
+    content_text STRING,
+    content_vector VECTOR(FLOAT, 768)
+);
+
+CREATE VECTOR INDEX users_vec_content_idx       -- 不同的表名前缀
+ON TABLE user_content(content_vector)
+PROPERTIES ("distance.function" = "cosine_distance");
+
+CREATE INVERTED INDEX users_inv_text_idx        -- 不同的表名前缀
+ON TABLE user_content(content_text)
+PROPERTIES ('analyzer' = 'chinese');
+```
+
+### 索引功能限制说明
+
+#### IF NOT EXISTS语法当前状态
+
+根据最新测试验证，索引创建语法当前**不支持** IF NOT EXISTS选项：
+
+```sql
+-- 不支持的索引IF NOT EXISTS语法（会导致语法错误）
+CREATE VECTOR INDEX IF NOT EXISTS vec_idx 
+ON TABLE example_table(embedding)
+PROPERTIES ("distance.function" = "cosine_distance");
+
+CREATE INVERTED INDEX IF NOT EXISTS text_idx
+ON TABLE example_table(content) 
+PROPERTIES ('analyzer'='chinese');
+
+CREATE BLOOMFILTER INDEX IF NOT EXISTS bloom_idx
+ON TABLE example_table(user_id);
+```
+
+在创建索引前，建议先检查索引是否存在，避免错误：
+
+```sql
+-- 推荐做法：先检查索引是否存在
+-- 然后再创建
+CREATE VECTOR INDEX vec_idx ON TABLE example_table(embedding)
+PROPERTIES ("distance.function" = "cosine_distance");
+```
+
+#### ARRAY类型列上的索引限制
+
+通过测试确认，在ARRAY类型列上创建倒排索引时存在以下限制：
+
+```sql
+-- ARRAY类型列不支持指定analyzer参数
+CREATE TABLE array_column_table (
+    id INT,
+    tags ARRAY<STRING>
+);
+
+-- 错误：ARRAY类型列指定analyzer
+CREATE INVERTED INDEX tags_analyzer_idx 
+ON TABLE array_column_table(tags)
+PROPERTIES ('analyzer' = 'keyword');  -- 失败！
+
+-- 正确：ARRAY类型列不指定analyzer
+CREATE INVERTED INDEX tags_idx 
+ON TABLE array_column_table(tags);  -- 成功
+
+-- 替代方案：使用STRING类型存储标签
+CREATE TABLE string_tags_table (
+    id INT,
+    tags_str STRING  -- 使用逗号分隔的标签字符串
+);
+
+CREATE INVERTED INDEX tags_str_idx 
+ON TABLE string_tags_table(tags_str)
+PROPERTIES ('analyzer' = 'keyword');  -- 成功
+```

+
+-- 避免的查询模式：无法利用分区剪枝
+SELECT user_id, COUNT(*) as activity_count
+FROM user_activity_logs 
+WHERE activity_time >= '2024-01-01 00:00:00'  -- 直接使用时间列，无法分区剪枝

+## ⚠️ 常见设计陷阱与解决方案
+
+### 数据类型设计陷阱
+
+#### 陷阱1：IDENTITY列类型错误
+
+**错误场景**:
+
+```sql
+-- 以下所有IDENTITY声明都会失败
+CREATE TABLE identity_type_errors (
+    id INT IDENTITY,                    -- 失败：不支持INT类型
+    small_id SMALLINT IDENTITY,         -- 失败：不支持SMALLINT类型
+    char_id CHAR(10) IDENTITY,          -- 失败：不支持字符类型
+    decimal_id DECIMAL(10,0) IDENTITY   -- 失败：不支持DECIMAL类型
+);
+
+-- 错误信息：invalid identity column type int, currently only BIGINT is supported
+```
+
+**正确解决方案**:
+
+```sql
+-- 正确：统一使用BIGINT IDENTITY
+CREATE TABLE identity_correct_usage (
+    id BIGINT IDENTITY,                 -- 唯一支持的IDENTITY类型
+    user_id INT NOT NULL,               -- 业务ID使用其他合适类型

+    sequence_num INT DEFAULT 1          -- 序列号使用普通INT
+) COMMENT 'IDENTITY列正确使用示例';
+```
+
+#### 陷阱2：VARCHAR长度设置不当
+
+**问题分析**:
+
+```sql
+-- 常见的长度设置错误
+CREATE TABLE varchar_length_problems (
+    name VARCHAR(10000),                -- 过度分配：浪费存储空间

+
+#### 陷阱3：金融计算使用浮点类型
+
+**风险演示**:
+
+```sql
+-- 浮点类型在金融计算中的精度问题
+CREATE TABLE financial_precision_risks (
+    account_id INT,
+    balance DOUBLE,                     -- 风险：浮点精度问题

+
+### 分区设计陷阱
+
+#### 陷阱4：不支持的分区列类型
+
+**错误场景**:
+
+```sql
+-- 不支持的分区列类型（测试确认会失败）
+CREATE TABLE partition_type_errors (
+    id INT,
+    amount DECIMAL(10,2),               -- DECIMAL不支持直接分区
+    price DOUBLE,                       -- DOUBLE不支持分区
+    created_time TIMESTAMP,             -- TIMESTAMP不能直接分区
+    location_point STRUCT<lat:DOUBLE,lng:DOUBLE> -- 复杂类型不支持分区
+) 
+PARTITIONED BY (created_time);          -- 失败！
+
+-- 错误信息示例：
+-- Unsupported data type for partition transform: timestamp_ltz
+```
+
+**正确解决方案**:
+
+```sql
+-- 使用生成列转换为支持的分区类型
+CREATE TABLE partition_type_solutions (
+    id INT,
+    amount DECIMAL(10,2),
+    price DOUBLE,
+    created_time TIMESTAMP,
+    location_point STRUCT<lat:DOUBLE,lng:DOUBLE>,
+    
+    -- 使用生成列转换TIMESTAMP为STRING（支持分区）

+    )
+) 
+PARTITIONED BY (date_partition)         -- 成功：STRING类型支持分区
+COMMENT '分区类型解决方案 - 使用生成列转换不支持的类型';
+```
+
+#### 陷阱5：动态分区数量超限
+
+**问题场景**:
+
+```sql
+-- 可能导致动态分区超限的操作
+INSERT INTO large_partition_table 
+SELECT * FROM source_table_with_many_dates;  -- 如果源表包含>2048个不同日期会失败
+
+-- 错误信息：
+-- The count of dynamic partitions exceeds the maximum number 2048
+```
+
+**解决方案策略**:
+
+```sql
+-- 策略1：分批按时间范围插入
+INSERT INTO large_partition_table 
+SELECT * FROM source_table_with_many_dates 
+WHERE event_date BETWEEN '2024-01-01' AND '2024-01-10';  -- 限制分区范围
+
+INSERT INTO large_partition_table 
+SELECT * FROM source_table_with_many_dates 
+WHERE event_date BETWEEN '2024-02-01' AND '2024-02-29';  -- 第二批：29个分区
+
+-- 策略2：按分区值分批插入
+INSERT INTO large_partition_table 
+SELECT * FROM source_table_with_many_dates 
+WHERE region IN ('north', 'south', 'east', 'west');     -- 限制为4个分区
+
+-- 策略3：预先过滤数据
+WITH filtered_source AS (
+    SELECT *, 
+           date_format(event_timestamp, 'yyyy-MM-dd') as date_part
+    FROM source_table_with_many_dates 
+    WHERE event_timestamp >= '2024-01-01'                -- 预过滤减少分区数
+      AND event_timestamp < '2024-02-01'
+)
+INSERT INTO large_partition_table 
+SELECT * FROM filtered_source;
+
+-- 策略4：应用层循环控制（伪代码）
+-- for month in ['2024-01', '2024-02', ...]:
+--     INSERT INTO table SELECT * FROM source WHERE month_partition = month
+```
+
+### 索引设计陷阱
+
+#### 陷阱6：索引命名管理
+
+**重要更新**: 经测试验证，当前版本的云器Lakehouse严格强制schema级索引名称唯一性。
+
+**推荐的命名实践**:
+
+```sql
+-- 使用表名前缀的唯一索引命名
+CREATE TABLE orders (
+    order_id INT,
+    customer_id INT,
+    order_content STRING
+);
+CREATE INVERTED INDEX orders_inv_customer_idx ON TABLE orders(customer_id);
+CREATE INVERTED INDEX orders_inv_content_idx ON TABLE orders(order_content) 
+PROPERTIES('analyzer'='keyword');
+
+CREATE TABLE products (
+    product_id INT,
+    customer_id INT,
+    product_description STRING
+);
+CREATE INVERTED INDEX products_inv_customer_idx ON TABLE products(customer_id);
+CREATE INVERTED INDEX products_inv_desc_idx ON TABLE products(product_description) 
+PROPERTIES('analyzer'='chinese');
+
+-- 推荐的索引命名规范
+-- 格式：{table_name}_{index_type}_{column_name}_idx
+-- 示例：users_bloom_email_idx, orders_vec_features_idx
+```
+
+#### 陷阱7：PRIMARY KEY约束与HASH CLUSTERED BY冲突
+
+**问题场景**:
+
+```sql
+-- PRIMARY KEY约束与HASH CLUSTERED BY冲突
+CREATE TABLE table_with_conflict (
+    tenant_id VARCHAR(50) PRIMARY KEY,
+    tenant_name VARCHAR(200) NOT NULL,
+    tenant_status TINYINT DEFAULT 1
+) 
+HASH CLUSTERED BY (tenant_id)            -- 与PRIMARY KEY冲突
+INTO 32 BUCKETS;
+
+-- 错误信息：CLUSTERED BY definition conflicts with enforced PRIMARY KEY
+-- or UNIQUE constraints defined at :[31,2], must HASH CLUSTERED BY ... SORTED BY ... ASC
+-- with all PRIMARY KEY or UNIQUE columns
+```
+
+**解决方案**:
+
+```sql
+-- 方案1：移除PRIMARY KEY约束，使用普通非空列
+CREATE TABLE solution_remove_pk (
+    tenant_id VARCHAR(50) NOT NULL,       -- 移除PRIMARY KEY
+    tenant_name VARCHAR(200) NOT NULL,
+    tenant_status TINYINT DEFAULT 1
+) 
+HASH CLUSTERED BY (tenant_id)
+INTO 32 BUCKETS;
+
+-- 方案2：调整HASH CLUSTERED BY与SORTED BY以符合要求
+CREATE TABLE solution_adjust_cluster (
+    tenant_id VARCHAR(50) PRIMARY KEY,
+    tenant_name VARCHAR(200) NOT NULL,
+    tenant_status TINYINT DEFAULT 1
+) 
+HASH CLUSTERED BY (tenant_id)            -- 保持与PRIMARY KEY一致
+SORTED BY (tenant_id ASC)                -- 添加排序且为ASC
+INTO 32 BUCKETS;
+```
+
+#### PRIMARY KEY与分桶策略最佳实践
+
+基于测试验证的结果，我们建议遵循以下设计指导：
+
+1. **避免同时使用**：在大多数场景下，建议避免同时使用PRIMARY KEY约束和HASH CLUSTERED BY，而是选择其中一种：
+   * 对于需要唯一性约束的场景，使用PRIMARY KEY
+   * 对于需要性能优化的大表，使用HASH CLUSTERED BY和布隆过滤器索引
+
+2. **必须同时使用时的规则**：如果业务需要同时使用，必须满足以下全部条件：
+   * HASH CLUSTERED BY的列必须包含PRIMARY KEY的全部列
+   * 必须添加SORTED BY子句
+   * SORTED BY子句必须包含PRIMARY KEY的全部列
+   * SORTED BY的所有PRIMARY KEY列都必须使用ASC排序方向
+
+3. **示例参考**：
+
+```sql
+-- 最佳实践1：仅使用PRIMARY KEY（小表推荐）
+CREATE TABLE customer_profiles (
+    customer_id INT PRIMARY KEY,
+    customer_name VARCHAR(100) NOT NULL,
+    customer_email VARCHAR(200)
+);
+
+-- 最佳实践2：仅使用HASH CLUSTERED BY（大表推荐）
+CREATE TABLE customer_events (
+    event_id BIGINT IDENTITY,
+    customer_id INT NOT NULL,
+    event_type VARCHAR(50),
+    event_time TIMESTAMP
+)
+HASH CLUSTERED BY (customer_id)
+SORTED BY (event_time DESC)
+INTO 128 BUCKETS;
+
+-- 创建布隆过滤器索引实现高效查找
+CREATE BLOOMFILTER INDEX customer_lookup_idx 
+ON TABLE customer_events(customer_id);
+
+-- 最佳实践3：必须同时使用时的正确配置
+CREATE TABLE order_items (
+    order_id INT,
+    item_id INT,
+    product_id INT,
+    quantity INT,
+    PRIMARY KEY (order_id, item_id)
+)
+HASH CLUSTERED BY (order_id, item_id)  -- 包含所有PRIMARY KEY列
+SORTED BY (order_id ASC, item_id ASC)  -- 包含所有PRIMARY KEY列且都是ASC
+INTO 64 BUCKETS;
+```
+
+#### 陷阱8：ARRAY类型列上错误使用analyzer
+
+**错误场景**:
+
+```sql
+-- 在ARRAY类型列上使用analyzer会导致错误
+CREATE TABLE array_column_table (
+    id INT,
+    tags ARRAY<STRING>
+);
+
+CREATE INVERTED INDEX tags_analyzer_idx 
+ON TABLE array_column_table(tags)
+PROPERTIES ('analyzer' = 'keyword');  -- 失败！ARRAY类型不支持analyzer参数
+
+-- 错误信息示例：
+-- invalid.inverted.index.analyzer.type, array<string>
+```
+
+**正确解决方案**:
+
+```sql
+-- 正确：ARRAY类型列上创建倒排索引时不指定analyzer
+CREATE INVERTED INDEX tags_idx 
+ON TABLE array_column_table(tags);  -- 成功：不指定analyzer
+
+-- 或者使用STRING类型存储并使用分隔符
+CREATE TABLE string_tags_table (
+    id INT,
+    tags_str STRING  -- 使用逗号分隔的标签字符串
+);
+
+CREATE INVERTED INDEX tags_str_idx 
+ON TABLE string_tags_table(tags_str)
+PROPERTIES ('analyzer' = 'keyword');  -- 成功：STRING类型支持analyzer
+```
+
+### 生成列设计陷阱
+
+#### 陷阱9：生成列使用非确定性函数
+
+**错误场景**:
+
+```sql
+-- 生成列中使用非确定性函数（测试确认会失败）
+CREATE TABLE generated_column_errors (
+    id INT,
+    event_data VARCHAR(1000),
+    
+    -- 以下生成列都会导致创建失败
+    auto_timestamp TIMESTAMP GENERATED ALWAYS AS (current_timestamp()),    -- 失败
+    random_id DOUBLE GENERATED ALWAYS AS (random()),                       -- 失败
+    current_user_name STRING GENERATED ALWAYS AS (current_user()),         -- 失败
+    uuid_value STRING GENERATED ALWAYS AS (uuid())                         -- 失败
+);
+
+-- 错误信息：Generated column auto_timestamp only contains built-in/scalar/deterministic function
+```
+
+**正确解决方案**:
+
+```sql
+-- 区分生成列和默认值的正确使用
+CREATE TABLE generated_column_solutions (
+    id INT,
+    event_time TIMESTAMP,
+    event_data VARCHAR(1000),
+    amount DECIMAL(10,2),
+    
+    -- 使用DEFAULT值代替生成列（适用于非确定性函数）
+    created_timestamp TIMESTAMP DEFAULT current_timestamp(),
+    random_seed DOUBLE DEFAULT random(),
+    creator_name STRING DEFAULT current_user(),
+    
+    -- 生成列使用确定性函数（从其他列计算得出）
+    event_year INT GENERATED ALWAYS AS (year(event_time)),
+    event_date STRING GENERATED ALWAYS AS (date_format(event_time, 'yyyy-MM-dd')),
+    data_length INT GENERATED ALWAYS AS (length(event_data)),
+    amount_category STRING GENERATED ALWAYS AS (
+        if(amount < 100, 'small', 
+           if(amount < 1000, 'medium', 'large'))
+    ),
+    display_info STRING GENERATED ALWAYS AS (
+        concat('[', string(id), '] ', substr(event_data, 1, 50))
+    )
+) COMMENT '生成列正确使用 - 区分确定性计算和默认值设置';
+```

+## 🔧 故障排查指南
+
+### 常见错误诊断和解决方案
+
+#### 错误1：IDENTITY列类型错误
+
+**错误信息**:
+
+```
+invalid identity column type int, currently only BIGINT is supported
+```
+
+**原因分析**: 尝试在非BIGINT列上使用IDENTITY约束
+
+**诊断步骤**:
+
+1. 检查CREATE TABLE语句中的IDENTITY列定义
+2. 确认IDENTITY列的数据类型是否为BIGINT
+3. 检查是否误用了INT、SMALLINT等其他数值类型
+
+**解决方案**:
+
+```sql
+-- 错误用法
+CREATE TABLE wrong_table (id INT IDENTITY, name VARCHAR(50));
+
+-- 正确用法  
+CREATE TABLE correct_table (id BIGINT IDENTITY, name VARCHAR(50));
+```
+
+#### 错误2：索引命名管理
+
+**重要更新**: 经实际测试验证，当前版本的云器Lakehouse在索引命名方面**可能不严格强制schema级唯一性**。虽然测试中相同名称的索引可以创建成功，但为了代码的可维护性和未来版本兼容性，仍建议使用唯一的索引命名。
+
+**最佳实践**:
+
+```sql
+-- 推荐的唯一索引命名
+CREATE INVERTED INDEX table1_inv_content_idx ON TABLE table1(content);
+CREATE INVERTED INDEX table2_inv_content_idx ON TABLE table2(content);
+
+-- 命名规范：{table_name}_{index_type}_{column_name}_idx
+```
+
+#### 错误3：生成列函数不支持
+
+**错误信息**:
+
+```
+Generated column auto_timestamp only contains built-in/scalar/deterministic function
+```
+
+**原因分析**: 生成列中使用了非确定性函数
+
+**诊断步骤**:
+
+1. 检查生成列表达式中使用的函数
+2. 对照确定性函数支持列表
+3. 区分默认值和生成列的使用场景
+
+**解决方案**:
+
+```sql
+-- 错误：在生成列中使用非确定性函数
+created_at TIMESTAMP GENERATED ALWAYS AS (current_timestamp())
+
+-- 正确：使用默认值
+created_at TIMESTAMP DEFAULT current_timestamp()
+
+-- 正确：生成列使用确定性函数
+date_part STRING GENERATED ALWAYS AS (date_format(some_timestamp, 'yyyy-MM-dd'))
+```
+
+#### 错误4：分区类型不支持
+
+**错误信息**:
+
+```
+Unsupported data type for partition transform: timestamp_ltz
+```
+
+**原因分析**: 使用了不支持分区的数据类型
+
+**诊断步骤**:
+
+1. 检查分区列的数据类型
+2. 对照支持分区的数据类型列表
+3. 评估是否可以使用生成列转换
+
+**解决方案**:
+
+```sql
+-- 错误：直接使用TIMESTAMP分区
+PARTITIONED BY (created_time)
+
+-- 正确：使用生成列转换
+CREATE TABLE correct_partition (
+    created_time TIMESTAMP,
+    date_part STRING GENERATED ALWAYS AS (date_format(created_time, 'yyyy-MM-dd'))
+) PARTITIONED BY (date_part);
+```
+
+#### 错误5：动态分区数量超限
+
+**错误信息**:
+
+```
+The count of dynamic partitions exceeds the maximum number 2048
+```
+
+**原因分析**: 单次插入操作涉及的动态分区数量超过2048个
+
+**诊断步骤**:
+
+1. 分析源数据的分区键分布
+2. 统计涉及的不同分区值数量
+3. 评估数据插入策略
+
+**解决方案**:
+
+```sql
+-- 查询源数据的分区分布
+SELECT partition_column, COUNT(*) 
+FROM source_table 
+GROUP BY partition_column 
+ORDER BY COUNT(*) DESC;
+
+-- 分批插入数据
+INSERT INTO target_table 
+SELECT * FROM source_table 
+WHERE date_column BETWEEN '2024-01-01' AND '2024-01-31';
+```
+
+#### 错误6：ARRAY类型列索引指定analyzer
+
+**错误信息**:
+
+```
+invalid.inverted.index.analyzer.type, array<string>
+```
+
+**原因分析**: 在ARRAY类型列上创建倒排索引时指定了analyzer参数
+
+**诊断步骤**:
+
+1. 检查CREATE INVERTED INDEX语句
+2. 确认索引列是否为ARRAY类型
+3. 检查是否包含analyzer参数
+
+**解决方案**:
+
+```sql
+-- 错误：ARRAY类型指定analyzer
+CREATE INVERTED INDEX tags_analyzer_idx 
+ON TABLE array_column_table(tags)
+PROPERTIES ('analyzer' = 'keyword');
+
+-- 正确：不指定analyzer
+CREATE INVERTED INDEX tags_idx 
+ON TABLE array_column_table(tags);
+```
+
+### 性能问题诊断
+
+#### 查询性能慢
+
+**可能原因和解决方案**:
+
+1. **分区剪枝未生效**
+   ```sql
+   -- 检查查询是否使用分区列
+   EXPLAIN SELECT * FROM table WHERE partition_column = 'value';
+
+   -- 确保WHERE条件包含分区列
+   WHERE date_partition = '2024-01-15'  -- 而不是 WHERE original_date = '2024-01-15'
+   ```
+
+2. **缺少合适的索引**
+   ```sql
+   -- 为高频查询列创建索引
+   CREATE BLOOMFILTER INDEX table_column_idx ON TABLE table_name(column_name);
+   ```
+
+3. **分桶策略不当**
+   ```sql
+   -- 检查分桶列的基数分布
+   SELECT bucket_column, COUNT(*) 
+   FROM table_name 
+   GROUP BY bucket_column 
+   ORDER BY COUNT(*) DESC;
+
+   -- 选择高基数、分布均匀的列作为分桶键
+   ```
+
+#### 写入性能差
+
+**可能原因和解决方案**:
+
+1. **分桶数量设置不当**
+   ```sql
+   -- 小表使用过多分桶 → 减少分桶数
+   -- 大表使用过少分桶 → 增加分桶数
+   ```
+
+2. **数据倾斜问题**
+   ```sql
+   -- 选择更均匀分布的分桶键
+   HASH CLUSTERED BY (more_uniform_column)
+   ```
+
+3. **过多索引维护开销**
+   ```sql
+   -- 删除不必要的索引
+   DROP INDEX unnecessary_index_name;
+   ```

+# LangChain 框架简介
+
+LangChain 是一款开源的框架，旨在帮助开发人员构建基于大型语言模型（LLM）的应用程序。它通过以下几个核心优势，让开发过程变得更加高效和便捷：
+
+1. 数据源集成：LangChain 可以无缝地将 LLM 与实时数据库、API 等多源数据进行整合，确保生成的内容既准确又具有上下文性。
+2. 组件化流程设计：通过灵活配置任务链，将预处理、模型调用和后处理步骤清晰地串联起来，提高执行效率。
+3. 简化大模型访问：提供简洁的接口，降低使用 LLM 进行技术开发的门槛，快速实现复杂的 NLP 功能。
+4. 高度扩展定制：具备良好的可扩展性，能够满足不同业务场景的需求，帮助开发者充分发挥 LLM 的潜力。
+
+# 基本开发流程
+
+本节将通过一个示例，展示如何结合使用 LangChain 和 clickzetta-sqlalchemy 来实现一个简单的查询 Lakehouse 并展示结果的应用。
+
+## 环境准备
+
+要使用 LangChain 与不同的数据源进行对接，您需要在 Python 环境中安装 `clickzetta-sqlalchemy`。安装方法如下：
+
+```shell
+pip install langchain clickzetta-sqlalchemy
+```
+
+## 示例代码
+
+首先，创建一个名为 `demo.py` 的文件，并编辑代码如下：
+
+```python
+from langchain_community.utilities import SQLDatabase
+import streamlit as st
+
+# 从 Streamlit 密钥管理器获取 Lakehouse 认证信息
+username = st.secrets.lakehouse.username
+password = st.secrets.lakehouse.password
+account = st.secrets.lakehouse.account
+endpoint = st.secrets.lakehouse.endpoint
+workspace = st.secrets.lakehouse.workspace
+schema = st.secrets.lakehouse.schema
+virtualcluster = st.secrets.lakehouse.virtualcluster
+
+# 创建连接字符串
+CONNECTION_STRING = (
+    f"clickzetta://{username}:{password}"
+    f"@{account}.{endpoint}/{workspace}?schema={schema}&virtualcluster={virtualcluster}"
+)
+
+# 从连接字符串创建 SQLDatabase 实例
+db = SQLDatabase.from_uri(CONNECTION_STRING, schema=schema)
+```
+
+接下来，执行查询并返回查询结果：
+
+```python
+# 执行查询
+result = db.run("SELECT * FROM Artist LIMIT 12;", fetch="cursor")
+# 打印结果类型
+print(type(result))
+# 展示查询结果
+pprint(list(result.mappings()))
+```
+
+为了绑定查询参数，请使用可选`parameters` 参数。
+
+```
+result = db.run("SELECT * FROM Artist WHERE Name LIKE :search;",parameters={"search": "p%"},fetch="cursor",)
+pprint(list(result.mappings()))
+```
+

+## LEFT 函数
+
+Lakehouse 中的 LEFT 函数用于从给定的字符串左侧提取指定数量的字符。需要注意的是，字符长度的单位是 utf8 字符，这意味着一个中文字符将被视为一个长度单位。
+
+### 函数语法
+
+LEFT 函数的语法格式如下：
+
+```Plaintext
+LEFT(str, len)
+```
+
+- `str`：待提取字符的字符串。该参数接受 VARCHAR 类型的数据。
+- `len`：需要从字符串左侧提取的字符数量。该参数应为正整数。
+
+### 返回值
+
+LEFT 函数返回一个字符串，包含从输入字符串左侧提取的指定数量的字符。返回值的数据类型为 VARCHAR。
+
+### 使用示例
+
+以下为 LEFT 函数的几个使用示例：
+
+#### 示例 1：
+
+```SQL
+SELECT LEFT('Hello, welcome to Lakehouse', 5);
+```
+
+此查询将返回字符串 'Hello, welcome to Lakehouse' 左侧的前 5 个字符，即 'Hello'。
+
+#### 示例 2：
+
+```SQL
+SELECT LEFT('Lakehouse，一个强大的实时数据仓库。', 9);
+```
+
+此查询将返回字符串 'Lakehouse，一个强大的实时数据仓库。' 左侧的前 9 个字符，即 'Lakehouse'。
+
+#### 示例 3：
+
+```SQL
+SELECT LEFT('The quick brown fox jumps over the lazy dog', 9);
+```
+
+此查询将返回字符串 'The quick brown fox jumps over the lazy dog' 左侧的前 9 个字符，即 'The quick'。
+
+### 注意事项
+
+- 确保 `len` 参数为正整数，否则函数将返回错误。
+- 如果 `len` 参数大于输入字符串的长度，LEFT 函数将返回整个输入字符串。

+# like运算符使用指南
+
+LIKE 运算符是一种在 SQL 查询语句中用于字符串匹配的工具，它可以帮助您判断一个字符串是否符合特定的模式。LIKE 运算符在进行匹配时是**区分大小写**的，这意味着 'A' 和 'a' 会被视为不同的字符。
+
+## 语法
+
+LIKE 运算符的基本语法如下：
+
+```SQL
+str [ NOT ] LIKE pattern
+```
+
+其中，`str` 是要匹配的字符串表达式，`pattern` 是要匹配的模式表达式。您还可以使用 `NOT` 关键字来反转匹配条件。
+
+此外，LIKE 运算符还支持与 `ANY`、`SOME` 或 `ALL` 关键字结合使用，以便在多个模式中进行匹配。当使用 `ALL` 时，`str` 必须匹配所有给定的模式；而使用 `ANY` 或 `SOME` 时，`str` 只需匹配至少一个模式。
+
+### 模式中的通配符
+
+LIKE 运算符的模式中包含以下两种特殊字符，用于表示通配匹配：
+
+* `_`：匹配任意单个字符（类似于 POSIX 正则表达式中的 `.`）。
+* `%`：匹配任意数量的字符（类似于 POSIX 正则表达式中的 `.*`）。
+
+## 使用示例
+
+假设我们有一个名为 `students` 的表，其中包含学生的姓名和班级信息，如下所示：
+
+```SQL
+CREATE TABLE students (
+  name STRING,
+  class STRING
+);
+
+INSERT INTO students (name, class) VALUES
+  ('Alice', 'A'),
+  ('Bob', 'B'),
+  ('Carol', 'A'),
+  ('David', 'C');
+```
+
+以下是一些使用 LIKE 运算符的查询示例，以及它们的输出结果：
+
+1.  查询班级中包含字母 "A" 的学生（区分大小写）：
+
+```SQL
+SELECT name, class
+FROM students
+WHERE class LIKE '%A%';
+
++-------+-------+
+| name  | class |
++-------+-------+
+| Alice | A     |
+| Carol | A     |
++-------+-------+
+```
+
+2.  查询姓名以 "A" 开头的学生（区分大小写）：
+
+```SQL
+SELECT name, class
+FROM students
+WHERE name LIKE 'A%';
+
++-------+-------+
+| name  | class |
++-------+-------+
+| Alice | A     |
++-------+-------+
+```
+
+3.  查询姓名以 "B" 或 "C" 开头的学生：
+
+```SQL
+SELECT name, class
+FROM students
+WHERE name LIKE ANY ('B%', 'C%');
+
++-------+-------+
+| name  | class |
++-------+-------+
+| Bob   | B     |
+| Carol | A     |
++-------+-------+
+```
+
+4.  查询姓名中同时包含字母 "a" 和 "l" 的学生：
+
+```SQL
+SELECT name, class
+FROM students
+WHERE name LIKE ALL ('%a%', '%l%');
+
++-------+-------+
+| name  | class |
++-------+-------+
+| Carol | A     |
++-------+-------+
+```
+
+5.  查询姓名不以 "D" 开头的学生：
+
+```SQL
+SELECT name, class
+FROM students
+WHERE name NOT LIKE 'D%';
+
++-------+-------+
+| name  | class |
++-------+-------+
+| Alice | A     |
+| Bob   | B     |
+| Carol | A     |
++-------+-------+
+```

+# 功能
+
+`SHOW PARTITIONS` 是一个在 SQL 中用于显示指定表的分区信息的命令。分区表是一种在数据仓库中常见的数据组织方式，它通过将数据分散存储在不同的分区中来优化查询性能和管理效率。使用 `SHOW PARTITIONS` 可以快速查看表的分区结构和每个分区的详细信息。
+
+# 使用限制
+
+* 目前使用 [实时sdk](java_reference/realtime-upload.md) 写入的分区无法立即查看，需要等待实时写入的数据提交后才能查看分区大小。
+
+# 语法
+
+```SQL
+SHOW PARTITIONS [EXTENDED] table_name [ PARTITION ( partition_col_name = partition_col_val [ , ... ] ) ]
+[WHERE <expr>]
+```
+
+## 参数说明
+
+* **EXTENDED**: 添加该关键字可以查看分区的文件数量、分区大小、分区条数和修改时间。
+* **table\_name**: 需要查询分区信息的表名，支持表、动态表、物化视图。
+* **PARTITION ( partition\_col\_name = partition\_col\_val** \[ , ... ] )**: 可选参数，用于指定要查看的分区的特定条件。通过指定分区键的值，可以过滤出特定的分区信息。
+* **WHERE \<expr>**: 可选参数，可以根据显示的字段进行过滤。支持根据 total\_rows、bytes、total\_files、created\_time 进行过滤。expr 支持 =、!=、>、< 、>= 、<=、 is null 、is not null、 between ...and、or、not 、<> 、IN。
+
+## 使用场景
+
+* **查看分区结构**: 了解表的分区策略和当前的分区情况，查看分区大小和修改时间。
+* **数据管理**: 在进行数据导入、导出或维护时，了解分区信息有助于更高效地管理数据。
+
+## 示例
+
+### 查看所有分区
+
+```SQL
+DROP TABLE IF EXISTS pt_table;

+本文档详细介绍了如何将本地数据导入Lakehouse平台。目前，Lakehouse支持三种主要的本地数据导入模式：
+
+1. 使用PUT命令上传本地文件，导入到Lakehouse中
+2. **通过Lakehouse Studio页面可视化上传**：适用于小数据量的文件上传，提供用户友好的界面和简化的上传流程。
+3. **使用JDBC客户端上传数据**：适合技术用户，尤其是需要批量处理小数据量文件的用户，支持快速处理CSV文件和脚本化、自动化操作。（在 JDBC 2.0.0 版本该功能已下线，推荐您使用 PUT 命令上传）
+
+
+## 应用场景
+
+* **PUT命令上传文件**：适用于源文件上传，并且需要使用 SQL 进行转换的场景。推荐在上传过程中使用 SQL 来转换或处理异常数据。支持 CSV、PARQUET、ORC 格式。
+* **Lakehouse Studio页面**：适合需要上传小数据量文件的用户，支持CSV、PARQUET、AVRO、ORC、TEXT格式，但不支持压缩文件格式。建议先在本地解压缩再上传。
+* **JDBC客户端**：仅支持 CSV 文件格式，不支持压缩文件，适合快速处理和自动化数据导入任务。在 JDBC 2.0.0 之后的版本中，本地 COPY 命令已被弃用。我们建议您使用 PUT 命令将数据上传到 Volume 中，然后使用服务器端的 COPY 命令进行导入。
+
+# 使用案例
+
+## 使用PUT命令上传数据
+
+Lakehouse目前内置了一些[Internal Volume](internal_volume.md)可以存储文件，Internal Volume目前支持USER VOLUME和TABLE VOLUME两种对象类型。我们通过 PUT 命令将文件上传到 Internal Volume，然后使用 COPY 命令将 Volume 数据导入到表中。
+
+**前置条件**
+
+* 已安装[命令行工具](connect-with-cli.md)。或者，您也可以使用开源工具如 DBeaver、SQL Workbench/J 来执行该命令。
+* 对目标表具有INSERT权限。
+
+1. 在命令行中执行PUT命令将文件上传至TABLE VOLUME
+
+```SQL
+--上传文件至user volume根目录
+PUT '/Users/Downloads/data.csv' TO TABLE VOLUME t_copy_from_volume FILE 'data.csv';
+```
+
+2. 使用[COPY INTO](copy-into-table.md)命令导入文件数据至目标表
+
+```SQL
+COPY INTO t_copy_from_volume FROM TABLE VOLUME t_copy_from_volume(id int, name string)  USING csv  
+OPTIONS(
+        'header'='true',
+        'lineSep'='\n'
+)
+FILES ('data.csv')
+--删除volume中的文件，节省存储
+PURGE=TRUE;
+;
+```
+
+## 使用Lakehouse Studio页面上传
+
+## 使用限制
+
+* **文件格式限制**：不支持复杂类型如ARRAY、MAP、STRUCT、JSON、INTERVAL。对于复杂类型数据，建议使用STRING类型映射，并通过Lakehouse SQL函数进行转化。
+* **文件大小限制**：Lakehouse Studio页面和Jdbc客户端支持的单个文件最大为2GB。
+* **COPY命令限制**：不支持在Studio页面上使用COPY命令上传本地文件。该命令需要指定本地文件路径，而Studio页面无法访问本地文件系统。
+在数据管理中，顶部区域还提供“上传”功能，支持将本地文件上传至云器 Lakehouse 平台。
+
+  ![](.topwrite/assets/image_1736307536920.png =640)
+
+点击“上传”按钮，您可以轻松将数据从本地文件加载到云器 Lakehouse 平台。支持 CSV 和 TXT 两种格式，上传文件的总大小不能超过 2 GB。
+
+![](.topwrite/assets/image_1714292021540.png =360)
+
+**格式说明**
+
+* **遇到错误**：当数据行中遇到异常数据等错误场景时的处理方式。
+
+* **列分隔符**：列之间的分隔符，只允许使用单个字符。对于 CSV 文件，默认为逗号。
+
+* **换行符**：设定换行符的处理方式，Windows 系统为 \r\n，Linux、macOS 系统为 \n。
+
+* **忽略表头**：指是否忽略上传文件中的表头。
+
+* **空值表示**：指定文件中空值（NULL）的表达方式。
+
+* **集群**：需要选择集群后，才能进行数据上传。
+
+* **数据写入方式**：
+
+  * **追加写入**：不对历史数据做处理，直接追加写入。
+  * **先清空后写入**：先清空表中的历史数据，然后写入新数据。

+# 批量从对象存储导入数据
+
+本文档详细介绍了如何使用 Lakehouse 的 SQL 引擎从对象存储中导入数据。目前，Lakehouse 支持两种主要的数据导入模式：
+
+1.  **使用 Volume 导入**：通过创建和管理对象存储上的 Volume 来导入数据。
+2.  **使用 COPY 命令导入**：利用 SQL 的 COPY 命令直接从对象存储中加载数据。
+
+# 参考文档
+
+[数据湖查询](structure_data_analysis.md)
+
+[COPY INTO](copy-into-table.md)
+
+# 应用场景
+
+*   利用 SQL 引擎的性能优势快速读取大量数据，高效处理大规模数据集。
+*   支持在数据导入过程中使用 SQL 进行数据转换，实现 ETL（Extract, Transform, Load）流程。
+*   建议在导入数据时选择通用型计算集群（GENERAL PURPOSE VIRTUAL CLUSTER），以适应批量作业和数据加载的需求。
+
+# 使用限制
+
+*   **对象存储支持**：目前 Volume 的目标对象存储仅支持阿里云 OSS 和腾讯云 COS。
+*   **费用说明**：从外部 Volume 下载文件可能会产生云账号的对象存储下载费用，具体费用请参考相应云服务商的计费说明。如果 Lakehouse 与对象存储位于同一地域，使用内网 Endpoint 可以避免额外费用。
+*   **跨云导入**：目前不支持跨云服务商导入数据（未来版本将支持）。
+
+# 使用案例
+
+## 使用Volume从OSS读取CSV数据导入

+# Lakehouse Map Join优化操作
+
+## 简介
+
+Map Join 是 Lakehouse 中一种高效的 JOIN 操作方式，特别适用于小表与大表的 JOIN 场景。Map Join 通过将小表广播到各个节点，直接在 Map 阶段完成 JOIN 操作，从而避免了昂贵的 Shuffle 和 Reduce 过程。这种优化方式可以节省资源，提高查询性能。
+
+## 语法
+
+要使用 Map Join，只需在查询语句中添加一个提示 `/*+ MAPJOIN (table) */`，其中 `table` 表示需要加载到内存中的小表名称。例如：
+
+```SQL
+SELECT /*+ MAPJOIN (t2) */ * FROM table1 t1
+JOIN table2 t2
+ON (t1.emp_id = t2.emp_id);
+```
+
+在这个例子中，`table2` 是一个小表，通过 Map Join 的方式，它会被加载到内存中，并与 `table1` 在 Map 阶段完成 JOIN 操作。
+
+## 优点
+
+Map Join 具有以下优点：
+
+1. 省去了 Shuffle 阶段，减少了网络传输和磁盘 I/O 的开销。
+2. 避免了数据倾斜问题，因为不需要按照 JOIN 列进行数据分发。
+3. 提高了查询执行速度，尤其对于小表 JOIN 大表的场景。
+
+## 缺点
+
+Map Join 存在以下限制：
+
+1. 小表必须能够完全加载到内存中，否则可能导致内存溢出或 Map Join 失败。目前 Lakehouse 限制小表大小为 1GB。
+2. Map Join 仅适用于小表与大表的 JOIN 操作，对于大表与大表的 JOIN 场景，则无法发挥优势。
+
+## 使用示例
+
+以下是一些 Map Join 的使用示例：
+
+### 示例1：员工信息与部门信息的关联查询
+
+```SQL
+SELECT /*+ MAPJOIN (dept) */ * FROM employees emp
+JOIN departments dept
+ON (emp.dept_id = dept.dept_id);
+```
+
+### 示例2：订单信息与客户信息的关联查询
+
+```SQL
+SELECT /*+ MAPJOIN (customer) */ * FROM orders order_
+JOIN customers customer
+ON (order_.customer_id = customer.customer_id);
+```
+
+### 示例3：销售记录与员工信息的关联查询
+
+```SQL
+SELECT /*+ MAPJOIN (employee) */ * FROM sales sales_
+JOIN employees employee
+ON (sales_.employee_id = employee.employee_id);
+```
+
+通过以上示例，您可以看到 Map Join 在不同场景下的应用。在实际使用中，请确保小表能够完全加载到内存中，以充分发挥 Map Join 的优势。

+# 元数据对象及权限（Privileges）
+
+## 权限定义
+
+访问控制权限的授予决定了用户可以对特定对象执行指定操作。对于云器Lakehouse中的每个元数据对象，都有一组可以授予的权限。云器Lakehouse中的所有元数据对象及其拥有的权限点，详见 权限点 文档。
+
+元数据对象有三种表达方式：
+
+1）以对象类型加对象名称，表达已被创建的对象。例如：table mytable（名称为mytable的表） 或 vcluster myvcluster（名称为myvcluster的计算集群）；
+
+2）以关键字 ALL 加对象类别，表达现有和未来所有该类型的对象。例如：ALL tables in schema my\_schema （名称为my\_schema的schema下的所有table类型对象）；
+
+3）以关键字ALL 加关键在 OBJECTS表达现有和未来的所有类型的所有对象，例如：ALL OBJECTS in workspace my\_workspace（名称为my\_workspace的工作空间下所有的对象）。
+
+权限点有两种表达方式：
+
+1）以具体权限点表达，例如：select，read metadata，update 等；
+
+2）以关键字 ALL 加关键字 PRIVILEGES，表达所有权限点，例如：ALL PRIVILEGES on table mytable（mytable表的所有权限点）。
+
+在使用SQL语句进行权限管理时，使用 GRANT <权限点> 和 REVOKE <权限点> 命令。在 GRANT <权限点> 语句末尾加上 WITH GRANT OPTION，表示在授予该权限点的同时，将允许被授予者将该权限点再授予其他角色或用户。
+
+## 元数据对象
+
+Lakehouse中的元数据对象及其父级对象如下表所示：
+
+| **元数据对象**         | **父级对象**  |
+| ----------------- | --------- |
+| workspace         | instance  |
+| share             | instance  |
+| network policy    | instance  |
+| schema            | workspace |
+| virtual cluster   | workspace |
+| connection        | workspace |
+| table             | schema    |
+| view              | schema    |
+| materialized view | schema    |
+| dynamic table     | schema    |
+| table stream      | schema    |
+| volume            | schema    |
+| index             | schema    |
+| function          | schema    |
+| job               | schema    |
+
+元数据对象均可以通过SQL进行授权。工作空间内的对象可在Web端，在“管理”-“安全”-“权限”中操作授权。
+
+### ALL 对象
+
+ALL 对象是一种特殊的元数据对象，表达一类对象下**当前**和**未来**的所有个体。例如：all tables表达当前和未来的所有table；all vclusters表达当前和未来的所有计算集群。
+
+ALL 对象在使用时，需要和关键字“IN”一起使用，以明确 ALL 对象描述的范围，关键字“IN”之后跟随的是 ALL 对象的父级对象。例如：all tables in schema my\_schema; all vclusters in workspace my\_workspace。
+
+ALL 对象的一种特殊用法是用于指代某父级对象下的所有自级对象，例如：all objects in schema my\_schema，表达my\_schema下的所有类型对象，包括table、view、functions等。
+
+注意：尽管ALL对象可以提升授权操作的效率，但请谨慎使用all objects的方式授权。仅在确认all objects指代的范围符合授权预期时，再使用all objects进行指代，避免授权范围超出预期。
+
+## 业务对象
+
+除元数据对象外，在数据开发、数据治理过程中，产生了业务对象，如下表所示：
+
+| **业务对象**           | **业务类别**              |
+| ------------------ | --------------------- |
+| 脚本（Script）         | 数据开发（development）     |
+| 任务和实例（Task）        | 监控规则（monitor rules）   |
+|                    | 通知策略（announce policy） |
+| 数据质量（Data Quality） | 质量规则（DQC rule）        |
+
+业务对象不可通过SQL进行授权。用户通过被授予包含业务对象权限的预置角色来获取相关权限。暂不支持对业务对象的细粒度授权。
+
+## 权限点
+
+### 服务实例（Instance） 权限点
+
+| **权限点**               | **用途** | **说明**                                     |
+| --------------------- | ------ | ------------------------------------------ |
+| create workspace      | 创建工作空间 | 默认授予实例管理员（instance\_admin角色），不支持授予其他角色或用户。 |
+| create network policy | 创建网络策略 | 默认授予实例管理员（instance\_admin角色），不支持授予其他角色或用户。 |
+| drop workspace        | 删除工作空间 | 默认授予实例管理员（instance\_admin角色），不支持授予其他角色或用户。 |
+
+### 工作空间（workspace）权限点
+
+| **限点**            | **用途**                    | **说明**                                            |
+| ----------------- | ------------------------- | ------------------------------------------------- |
+| alter workspace   | 修改工作空间                    | 默认授予该空间的空间管理员（workspace\_admin）角色，不支持授予其他角色或用户。   |
+| create connection | 创建connection对象            |                                                   |
+| create vcluster   | 创建计算集群（virtual cluster）对象 |                                                   |

+
+### ALL 权限点
+
+ALL 权限点是各类元数据对象上均存在的一个权限点，表达该对象的所有权限点。ALL权限点是一个**独立**的权限点，与其他权限点并非指代关系。因此授予ALL权限点不会覆盖授予其他权限点，解除ALL权限点也不会解除其他权限点。
+
+例如：对user my\_user 先后授予了example\_table的select和ALL权限点。则此时my\_user用户由于被授予了ALL权限点，可以对example\_table执行所有操作；在查询my\_user用户对example\_table的权限时，显示同时拥有的select和all权限点的授权。当对my\_user用户解除ALL权限点的授权时，my\_user用户仍具备对example\_table进行select操作的权限。
+
+使用ALL权限点可以快速完成对一个对象所有权限的授予，例如：
+
+```
+Grant all privileges on table example_table to user my_user;
+```

+Metabase是一款开源的商业智能平台，它能帮助您轻松地提出关于数据的问题，并将结果可视化。此外，Metabase还可以嵌入到您的应用程序中，让您的客户能够探索和分析他们的数据。
+
+![Metabase界面示例](.topwrite/assets/image_1704980255033.png)
+
+# 在Docker上部署Metabase
+
+Metabase官方提供了Docker镜像，方便您在任何支持Docker的系统上快速部署。本文档将指导您如何在Docker上部署Metabase，并连接到云器Lakehouse数据库。
+
+## 快速入门
+
+确保您已经安装并运行了Docker。接下来，按照以下步骤在本地运行Metabase的开源版本。
+
+1. 拉取最新的Docker镜像：
+
+   ```
+   docker pull metabase/metabase:v0.54.6
+   ```
+
+> **注意**：本指南使用 v0.54.6 版本，这是一个经过充分测试的稳定版本。
+
+2. 启动Metabase容器：
+
+   ```
+
+    docker run -d \
+      -p 3000:3000 \
+      --name metabase \
+      metabase/metabase:v0.54.6
+   ```
+
+   默认情况下，Metabase服务器将在端口3000上启动。
+
+3. 下载云器Lakehouse的Metabase驱动并复制到Docker容器中：
+   [clickzetta.metabase-driver.jar](https://autolake-dev-beijing.oss-cn-beijing.aliyuncs.com/clickzetta-tool/release/clickzetta.metabase-driver.jar)
+
+   ```
+docker cp clickzetta.metabase-driver.jar metabase-clickzetta:/plugins/clickzetta.metabase-driver.jar
+```
+
+4. 若要在其他端口上运行Metabase，例如端口12345，您可以使用以下命令：
+
+   ```
+   docker run -d -p 12345:3000 --name metabase-clickzetta metabase/metabase:latest
+   ```
+
+5. 启动完成后，访问 Metabase：`http://localhost:3000`（或您选择的其他端口）。
+
+# 连接云器Lakehouse
+
+## 配置数据库连接
+
+1. 登录到 Metabase，然后进入“Admin Settings”（管理员设置）页面。
+2. 在“Databases”（数据库）部分，点击“Add a database”（添加数据库）按钮。
+3. 选择云器Lakehouse作为数据库类型。
+4. 填写数据库连接信息，包括主机名、端口、数据库名称、用户名和密码等。
+5. 点击“Test connection”（测试连接）以确保连接成功。
+6. 点击“Save”（保存）按钮完成配置。
+
+![添加云器Lakehouse数据库连接](.topwrite/assets/image_1704980374686.png)
+
+## 浏览和分析数据
+
+1. 在Metabase中，点击左侧导航栏的“Browse Data”（浏览数据）选项。
+2. 选择您刚刚配置的云器Lakehouse数据库。
+3. 您将看到数据库中的所有表和视图。点击任意表或视图，Metabase将自动为您生成一个数据浏览界面。
+4. 您可以对数据进行筛选、排序和分组等操作，以便更好地分析数据。
+5. 若要创建更复杂的数据可视化报告，请点击Metabase顶部导航栏的“Create a dashboard”（创建仪表板）按钮，然后选择相应的数据表和可视化类型。

+# SHOW和DESC命令完整指南
+
+## 引言：元数据查询在业务中的重要性
+
+在现代数据湖仓架构中，元数据管理是数据治理和业务分析的基础。无论是数据工程师需要了解表结构、业务分析师查找可用数据源，还是系统管理员监控资源使用情况，都离不开高效的元数据查询能力。云器Lakehouse提供了完整的SHOW和DESC命令体系，帮助用户快速获取所需的元数据信息。
+
+### 典型业务场景
+
+**数据分析师场景**：新加入团队的分析师需要快速了解有哪些数据表可用，每个表包含什么字段，以及如何访问这些数据。
+
+**数据工程师场景**：在ETL流程开发中，需要确认上游表的Schema变化，检查数据管道状态，以及监控作业执行情况。
+
+**系统管理员场景**：需要监控计算集群资源使用，管理用户权限，以及优化存储和连接配置。
+
+**业务负责人场景**：需要了解数据资产概况，评估数据共享情况，以及确保数据安全合规。

+
+### 基本用法
+
+#### 1. 查看所有表
+
+```sql
+-- 显示当前Schema中的所有表对象
+SHOW TABLES;
+
+-- 限制返回数量
+SHOW TABLES LIMIT 10;
+```
+
+#### 2. 指定Schema查询
+
+```sql
+-- 查看特定Schema中的表
+SHOW TABLES IN production_schema;
+SHOW TABLES IN information_schema;
+
+-- 组合Schema和限制条件
+SHOW TABLES IN data_warehouse LIMIT 20;
+```
+
+#### 3. 模式匹配查询
+
+```sql
+-- 查找以特定前缀开头的表
+SHOW TABLES LIKE 'fact_%';
+SHOW TABLES LIKE 'dim_%';
+
+-- 查找包含特定字符串的表
+SHOW TABLES LIKE '%customer%';
+SHOW TABLES LIKE '%_temp';
+
+-- 单字符通配符
+SHOW TABLES LIKE 'table_?';
+```
+
+### 高级过滤条件
+
+#### 1. 按表类型过滤
+
+```sql
+-- 只显示普通表（排除视图）
+SHOW TABLES WHERE is_view = false;
+
+-- 只显示视图
+SHOW TABLES WHERE is_view = true;
+
+-- 只显示物化视图
+SHOW TABLES WHERE is_materialized_view = true;
+
+-- 只显示动态表
+SHOW TABLES WHERE is_dynamic = true;
+
+-- 只显示外部表
+SHOW TABLES WHERE is_external = true;
+```
+
+#### 2. 组合条件查询
+
+```sql
+-- 查找非外部的普通表
+SHOW TABLES WHERE is_view = false AND is_external = false;
+
+-- 查找所有类型的视图（包括物化视图）
+SHOW TABLES WHERE is_view = true OR is_materialized_view = true;
+
+-- 在指定Schema中查找动态表
+SHOW TABLES IN analytics_schema WHERE is_dynamic = true;
+
+-- 查找内部的数据表（排除视图和外部表）
+SHOW TABLES WHERE is_view = false 
+  AND is_external = false 
+  AND is_materialized_view = false;
+```
+
+#### 3. 复杂业务查询
+
+```sql
+-- 数据治理：查找所有需要监控的核心表
+SHOW TABLES WHERE is_external = false 
+  AND is_view = false 
+  AND table_name NOT LIKE '%_temp%'
+  AND table_name NOT LIKE '%_staging%';
+
+-- 性能分析：查找所有可能影响性能的动态表
+SHOW TABLES WHERE is_dynamic = true;
+
+-- 架构审计：查找所有外部依赖
+SHOW TABLES WHERE is_external = true;
+```
+
+### 语法限制和注意事项
+
+#### ✅ 支持的组合
+
+* `IN schema_name` + `WHERE condition`
+* `IN schema_name` + `LIMIT n`
+* `WHERE condition` + `LIMIT n`
+* `LIKE pattern` (单独使用)
+
+#### ❌ 不支持的组合
+
+```sql
+-- ❌ LIKE和WHERE不能同时使用
+-- SHOW TABLES LIKE 'test%' WHERE is_dynamic=true;
+
+-- 解决方案：使用WHERE条件中的LIKE操作
+SELECT schema_name, table_name, is_dynamic 
+FROM (SHOW TABLES) 
+WHERE table_name LIKE 'test%' AND is_dynamic = true;
+```
+
+### 实际应用场景
+
+#### 场景1：数据架构分析
+
+```sql
+-- 1. 了解Schema中的表分布
+SHOW TABLES IN production_schema;
+
+-- 2. 分析表类型分布
+SELECT 
+  CASE 
+    WHEN is_view THEN 'VIEW'
+    WHEN is_materialized_view THEN 'MATERIALIZED_VIEW'
+    WHEN is_dynamic THEN 'DYNAMIC_TABLE'
+    WHEN is_external THEN 'EXTERNAL_TABLE'
+    ELSE 'REGULAR_TABLE'
+  END as table_type,
+  COUNT(*) as count
+FROM (SHOW TABLES)
+GROUP BY table_type;
+```
+
+#### 场景2：数据清理和维护
+
+```sql
+-- 查找临时表和测试表
+SHOW TABLES WHERE table_name LIKE '%temp%' 
+  OR table_name LIKE '%test%' 
+  OR table_name LIKE '%staging%';
+
+-- 查找可能的备份表
+SHOW TABLES WHERE table_name LIKE '%_backup%' 
+  OR table_name LIKE '%_bak%'
+  OR table_name LIKE '%_old%';
+```
+
+#### 场景3：权限和安全审计
+
+```sql
+-- 查找所有外部数据源
+SHOW TABLES WHERE is_external = true;
+
+-- 查找需要特别关注的动态表
+SHOW TABLES WHERE is_dynamic = true;
+
+-- 按Schema分析表的分布
+SELECT schema_name, COUNT(*) as table_count
+FROM (SHOW TABLES)
+GROUP BY schema_name
+ORDER BY table_count DESC;
+```
+
+#### 场景4：开发环境管理
+
+```sql
+-- 开发环境：查找个人开发表
+SHOW TABLES LIKE '%_dev_%';
+SHOW TABLES LIKE 'tmp_%';
+
+-- 生产环境：查找核心业务表
+SHOW TABLES IN production 
+WHERE is_view = false 
+  AND is_external = false
+  AND table_name LIKE 'fact_%' 
+   OR table_name LIKE 'dim_%';
+```
+
+### 性能优化建议
+
+#### 1. 使用精确过滤
+
+```sql
+-- ✅ 好的做法：使用精确条件
+SHOW TABLES IN specific_schema WHERE is_dynamic = true;
+
+-- ❌ 避免：查询所有后过滤
+-- SELECT * FROM (SHOW TABLES) WHERE schema_name = 'specific_schema';
+```
+
+#### 2. 合理使用LIMIT
+
+```sql
+-- 在大型环境中总是使用LIMIT
+SHOW TABLES LIMIT 50;
+SHOW TABLES IN large_schema LIMIT 100;
+```
+
+#### 3. 组合查询策略
+
+```sql
+-- 第一步：快速概览
+SHOW TABLES IN target_schema LIMIT 10;
+
+-- 第二步：精确查找
+SHOW TABLES IN target_schema WHERE is_dynamic = true;
+
+-- 第三步：详细分析
+SELECT table_name, is_view, is_dynamic, is_external
+FROM (SHOW TABLES IN target_schema)
+WHERE table_name LIKE '%customer%';
+```
+
+### 与其他命令的配合使用
+
+```sql
+-- 结合DESC命令进行深度分析
+SELECT table_name FROM (SHOW TABLES WHERE is_dynamic = true);
+-- 然后对每个动态表执行：DESC TABLE table_name;
+
+-- 结合Information Schema获取更多信息
+SELECT t.table_name, t.is_dynamic, i.create_time, i.row_count
+FROM (SHOW TABLES WHERE is_dynamic = true) t
+LEFT JOIN information_schema.tables i 
+  ON t.table_name = i.table_name 
+  AND t.schema_name = i.table_schema;
+```
+

+
+## 故障排查指南
+
+### 常见问题和解决方案
+
+| 问题类型      | 可能原因              | 解决方案                         |
+| --------- | ----------------- | ---------------------------- |
+| **对象不存在** | 对象名称错误或不在当前Schema | 使用`SHOW SCHEMAS`确认范围，检查对象名拼写 |
+| **权限不足**  | 用户缺少相应访问权限        | 联系管理员，使用`SHOW GRANTS`检查当前权限  |
+| **语法错误**  | 命令语法不正确           | 参考本文档语法说明，注意对象类型名称           |
+| **结果为空**  | 指定条件过于严格或对象确实不存在  | 放宽查询条件，使用更通用的查询              |
+
+### 调试步骤
+
+```sql
+-- 1. 确认当前上下文
+SELECT current_workspace(), current_schema(), current_user(), current_vcluster();
+
+-- 2. 检查基本权限
+SHOW GRANTS;
+
+-- 3. 验证对象存在性
+SHOW SCHEMAS;
+SHOW TABLES LIMIT 10;
+
+-- 4. 测试简单查询
+SHOW TABLES LIMIT 5;
+```
+
+## 结合Information Schema的深度分析
+
+### 元数据深度挖掘
+
+```sql
+-- 使用SHOW命令快速定位
+SHOW TABLES LIKE '%fact%';
+
+-- 结合Information Schema深度分析
+SELECT table_name, table_type, create_time, row_count
+FROM information_schema.tables 
+WHERE table_name LIKE '%fact%'
+  AND table_schema = 'data_warehouse'
+ORDER BY create_time DESC;
+
+-- 分析作业执行模式
+SHOW JOBS LIMIT 5;
+
+SELECT job_creator, COUNT(*) as job_count, 
+       AVG(execution_time) as avg_execution_time
+FROM information_schema.job_history 
+WHERE pt_date >= CURRENT_DATE - INTERVAL '7 DAYS'
+GROUP BY job_creator
+ORDER BY job_count DESC;
+```
+
+### 自动化监控查询
+
+```sql
+-- 集群状态监控（直接查询，不创建视图）
+SELECT 
+    'VCLUSTER' as resource_type,
+    name as resource_name,
+    state as status,
+    current_vcluster_size as current_size,
+    running_jobs as active_jobs
+FROM (SHOW VCLUSTERS)
+WHERE state != 'RUNNING';
+```
+
+## 语法限制和注意事项
+
+### Information Schema列名规范
+
+```sql
+-- ✅ 正确的列名
+SELECT table_schema, table_name, table_type, create_time, row_count
+FROM information_schema.tables;
+
+-- ❌ 错误的列名
+-- SELECT schema_name, created_time FROM information_schema.tables;
+```
+
+### SHOW命令在视图中的限制
+
+* ✅ **支持**：直接在FROM子句中使用SHOW命令
+* ❌ **不支持**：创建包含SHOW命令的视图后进行查询
+
+```sql
+-- ✅ 支持的用法
+SELECT name, state FROM (SHOW VCLUSTERS);
+
+-- ❌ 不推荐的用法
+-- CREATE VIEW cluster_view AS SELECT * FROM (SHOW VCLUSTERS);
+-- SELECT * FROM cluster_view;  -- 查询会失败
+```
+
+### 数据类型处理
+
+```sql
+-- ✅ execution_time已经是double类型，无需转换
+SELECT AVG(execution_time) FROM information_schema.job_history;
+
+-- ❌ 不必要的类型转换
+-- SELECT AVG(CAST(execution_time AS DOUBLE)) FROM information_schema.job_history;
+```
+
+## 最佳实践总结
+
+### 1. 日常运维检查清单
+
+**每日检查**
+
+* `SHOW VCLUSTERS` - 检查集群状态
+* `SHOW JOBS LIMIT 20` - 监控作业执行
+* `SHOW CONNECTIONS` - 验证连接状态
+
+**每周检查**
+
+* `SHOW SHARES` - 审计数据共享

+## 创建答案构建器：
+
+答案构建器用于定义有复杂计算逻辑的指标，以及回答明细查询的 SQL 模板。在**左侧导航栏：数据** -> **答案构建器** 中，可以点击 “+ **新建答案构建器**” ，按步骤填写代码。
+
+* 答案构建器的 SQL 模板：其中 `${dims} `和 `${filters}` 为固定写法，代表维度与过滤条件的变量，变量可选的列在模板下方的过滤条件与维度的选择区域 **Filters** 和 **Dims** 部分定义
+
+```SQL
+SELECT  
+  ${dims},
+  sum(op.payment_value) as total_sales_bz,
+  avg(op.payment_value) as avg_sales_bz
+FROM datagpt_ws.public.v_gpt_orders AS o  
+LEFT JOIN datagpt_ws.public.v_gpt_order_items AS oi 
+    ON o.order_id = oi.order_id  LEFT JOIN datagpt_ws.public.v_gpt_products AS p
+    ON oi.product_id = p.product_id  LEFT JOIN datagpt_ws.public.v_gpt_customers AS c
+    ON o.customer_id = c.customer_id  LEFT JOIN datagpt_ws.public.v_gpt_payments AS op
+    ON o.order_id = op.order_id  LEFT JOIN datagpt_ws.public.v_gpt_sellers AS os ON oi.seller_id = os.seller_id
+where ${filters}
+group by ${dims}
+```
+
+* **Filters 与Dims 变量定义**：注：此处未出现在 Filter 和 Dims 中的列，不会作为问题的过滤条件和维度。（此处与 **数据** -> **数据表** 中，表列的**用途**字段配置关联：即在**用途**字段中被配置为 FILTER 和 DIM 的列，会在此处默认被选中，最终以此页面的配置为准）
+* ![](.topwrite/assets/c.jpg =601)
+
+### 配置指标别名和分析方法：
+
+一个指标模板中，可以定义多个指标。每个指标可以指定多个别名。
+
+> 注意：在系统 Default Domain （默认域）中，允许指标以及别名重复；在其它用户创建的 Domain 中，不允许指标名称（包括别名）重复
+
+### **分析方法**：
+
+* **可加型指标**：同环比的算法为：（本期值-上期值）/ 上期值的绝对值
+* **比例型指标**：同环比的算法为：本期值 - 上期值。例如今年市场占有率30%，去年20%，那就是同比增长10%。

+
+# 方式一：在 Docker上运行配置MindsDB
+
+## 安装 Docker
+
+如果您还没有安装Docker，请按照[说明](https://docs.docker.com/install)在您的计算机上安装 Docker 。要确保 Docker 已成功安装在您的计算机上，请测试Docker是否正常运行，如下所示：
+
+```bash
+docker run hello-world
+```
+
+您应该会看到`Hello from Docker!`消息。否则，请查看 [Docker 的入门](https://www.docker.com/get-started)文档。
+
+**适用于 Mac 用户的 Docker - RAM 分配问题**
+
+默认情况下，Docker for Mac 分配 2 GB RAM，这不足以使用 Docker 部署 MindsDB。我们建议将默认 RAM 限制增加到 8 GB。 有关如何增加分配内存的更多信息，请参阅 [Docker Desktop for Mac 用户手册。](https://docs.docker.com/desktop/mac/#resources)
+
+## 安装并启动 MindsDB
+
+请注意，这种 MindsDB 安装方法至少需要 8 GB RAM 和 20 GB 可用存储空间。
+
+下载docker compose文件到本地:
+
+<https://github.com/clickzetta/mindsdb-clickzetta/blob/staging/docker-compose-up-only.yml>
+
+运行以下命令在 Docker 中启动 MindsDB。
+
+```bash
+docker-compose -f docker-compose-up-only.yml up -d
+```
+
+现在，您可以访问以下内容：
+
+MindsDB Studio：
+
+```bash
+http://127.0.0.1:47334/
+```
+
+使用 MySQL 的 MindsDB
+
+```bash
+mysql -h 127.0.0.1 --port 47335 -u mindsdb -p
+```
+
+## 下一步
+
+现在您已经在 Docker 容器中本地安装并启动了 MindsDB，接下来了解如何使用该[CREATE MODEL](https://docs.mindsdb.com/sql/create/model)语句创建和训练模型。在**MindsDB SQL**部分，您将找到 MindsDB 提供的 SQL 语法的全面概述。我们还提供了**MindsDB Mongo-QL**部分中记录的 Mongo-QL 语法。
+
+您可以将 MindsDB 连接到不同的客户端，包括[MySQL CLI](https://docs.mindsdb.com/connect/mysql-client)。
+
+查看[用例](https://docs.mindsdb.com/finetune/anyscale)部分，了解涵盖大型语言模型、自然语言处理、时间序列、分类和回归模型的教程。
+
+# 方式二：通过 pip和github源代码搭建MindsDB
+
+本节介绍如何从源代码部署MindsDB。如果您想为我们的代码做出贡献或调试 MindsDB，那么这是使用 MindsDB 的首选方式。
+
+要成功安装 MindsDB，请使用**Python 64 位版本**。另外，请确保**Python >= 3.8**且**pip >= 20.3**。
+
+## 安装
+
+请注意，这种 MindsDB 安装方法需要至少 6 GB 的可用存储空间。
+
+1. 克隆 MindsDB 存储库：
+
+   ```bash
+   git clone https://github.com/clickzetta/mindsdb-clickzetta.git
+   ```
+
+2. 创建新的虚拟环境：
+
+   ```bash
+   python -m venv mindsdb-venv
+   ```
+
+3. 激活虚拟环境：
+
+   ```bash
+   source mindsdb-venv/bin/activate
+   ```
+
+4. 安装依赖项：
+
+   ```bash
+   cd mindsdb
+   pip install -e .
+   pip install -r requirements/requirements-dev.txt
+   ```
+
+5. 启动MindsDB：
+
+   ```bash
+   python -m mindsdb  --config=config.json
+   ```
+
+默认情况下，MindsDB 将始终启动`http`和`mysql`API。
+
+```bash
+python -m mindsdb --api=http,mysql  --config=config.json
+```
+
+如果您想使用 Mongo API，您需要将其作为参数提供给`--api`. 您可以按如下方式进行操作：
+
+```bash
+python -m mindsdb --api=http,mongodb,mysql  --config=config.json
+```
+
+6. 现在，您可以访问以下内容：
+
+MindsDB Studio：
+
+```bash
+http://127.0.0.1:47334/
+```
+
+使用 MySQL 的 MindsDB
+
+```bash
+mysql -h 127.0.0.1 --port 47335 -u mindsdb -p
+```
+
+## 依赖关系
+
+默认情况下，不会安装许多数据或 ML 集成的依赖项。
+
+如果您想要使用默认情况下不可用的依赖项的数据或 ML 集成，请通过运行以下命令进行安装：
+
+```
+pip install '.[handler_name]'
+```
+
+您可以在此处找到所有可用的[处理程序](https://github.com/clickzetta/mindsdb-clickzetta/tree/staging/mindsdb/integrations/handlers)。
+
+## 故障排除
+
+### Pip 和 Python 版本
+
+目前，MindsDB 支持 Python 版本 3.8.x、3.9.x、3.10.x 和 3.11.x。
+
+要成功安装 MindsDB，请使用**Python 64 位版本**。另外，请确保**Python >= 3.8**且**pip >= 20.3**。`pip --version`您可以通过运行和 命令来检查 pip 和 python 版本`python --version`。
+
+请注意，根据您的环境以及安装的 pip 和 python 软件包，您可能必须使用**pip3**而不是**pip**或**python3.x** 而不是**py**。例如，`pip3 install mindsdb`代替 `pip install mindsdb`.
+
+### 如何避免依赖性问题
+
+**使用pip**在虚拟环境中安装 MindsDB以避免依赖问题。
+
+### 如何避免常见错误
+
+MindsDB 需要大约 3 GB 的可用磁盘空间来安装其所有依赖项。确保分配最小。3 GB 磁盘空间以避免 `IOError: [Errno 28] No space left on device while installing MindsDB`错误。
+
+首先，激活安装 MindsDB 的虚拟环境。是为了避免`No module named mindsdb`错误。
+
+如果遇到该`This site can’t be reached. 127.0.0.1 refused to connect.` 错误，请检查MindsDB服务器控制台，查看服务器是否仍处于该`starting`阶段。但如果服务器已启动，但您仍然收到此错误，请在我们的 [GitHub 存储库](https://github.com/mindsdb/mindsdb/issues)上报告该错误。
+
+### 如何解决`ImportError: failed to find libmagic`的问题
+
+如果出现错误，您应该通过运行以下命令之一手动`ImportError: failed to find libmagic`安装：`libmagic`
+
+```bash
+pip install python-magic-bin  # for linux and windows
+brew install libmagic  # for macOS
+```
+
+# 检查云器Lakehouse Handler状态
+
+访问[MindsDB Studio](http://127.0.0.1:47334/editor)

+
+#### 触发条件规则
+
+触发条件由监控事项、指标计算方式、阈值和触发方式组成。当前系统支持“事件监控”和“指标监控”两种类型。
+
+**基于「指标」的监控配置**
+
+![](.topwrite/assets/226957dd01/0d872f1cb6d11f16e4a48c9a6466ac9d43eb8606.png =548)
+
+针对指标监控类型，在定义好计算方式和阈值后，支持两种触发方式的配置。
+
+持续：指标一旦连续N次触碰到阈值时，则会触发监控告警。
+
+检查间隔：用户需定义在检查间隔范围内累计N次触碰到阈值后，才会触发监控告警。
+
+指标监控配置：用户可以定义计算方式和阈值，并选择触发方式。例如，配置全增量一体同步任务延迟指标，延迟时间大于等于50秒，持续3个数据点，告警频次限制为30分钟发送一次。
+
+![](.topwrite/assets/226957dd01/4f091acaf0cca77057e17882d353011c0853801e.png =600)
+
+00:40的时候，发现连续3次在阈值之上，第一次触发告警。接下来一直到01:50的时候，均处于第一次告警阶段。
+
+在告警阶段，通过告警频次判断接下来的几个时间点，结合告警频次的配置决定是否持续发送告警。告警限制为30分钟发送一次，则会在01:10、01:40两个时间点发送告警通知。
+
+从02:00开始，接下来后面的三次指标均处于阈值之下，则第一次告警恢复，不再触发告警通知。
+
+若用户的触发方式是检查监控内的累积次数。
+
+**基于「事件」的监控配置**
+
+事件监控是基于特定事件或条件发生时产生的告警。用户可以基于当前产品内的运维实例或数据质量校验规则进行监控。基于产品内当前支持的行为，当前事件监控主要分为两大类：
+
+任务运维：用户在开发场景内通过配置调度场景定义的各类周期调度任务，或者实时运行任务实例。
+
+数据质量：用户在数据质量内配置的针对表质量的各类监控。
+
+> 可以查看 [监控项口径说明文档](monitoring_item_specification.md)，来了解详细的口径说明。
+
+#### 告警事件
+
+告警事件列表展示了所有触发监控规则后的告警信息。用户可以对列表中的告警事件进行操作，如抑制或关闭。
+
+抑制：设置当前告警事件在多少分钟内不再发送消息。
+
+关闭：关闭当前告警事件，不再接收这类消息。

+
+#### 告警事件处理操作
+
+| 操作                      | 定义                 | 适用场景                | 影响范围   |
+| ----------------------- | ------------------ | ------------------- | ------ |
+| 抑制                      | 设置告警事件在指定时间内不再发送消息 | 已知问题正在处理中，暂时不需要重复告警 | 当前告警事件 |
+| 关闭                      | 关闭告警事件，停止接收此类消息    | 问题已解决或确认为误报         | 当前告警事件 |
+| 自动关闭告警  --不是在告警事件中点击处理的 | 系统检测到问题恢复后自动关闭告警   | 任务实例重跑成功、手动置成功      | 相关告警事件 |

+## 配置管理
+
+配置管理允许用户对个人信息和Webhook进行配置。
+
+### 个人配置
+
+用户可以在个人配置中修改接收告警的手机号和邮箱地址，并设置免打扰时段。
+
+![个人配置界面](.topwrite/assets/226957dd01/d7725ff84c1b3f1871e83dc4e23b576edad6d103.png =680)
+
+### Webhook配置
+
+Webhook配置用于定义告警推送所需的Webhook渠道，当前支持飞书和钉钉。
+
+![Webhook配置界面](.topwrite/assets/226957dd01/6a8bc6fc74fb8f046f7169d91fac4169aab3b968.png =680)
+
+#### 新建Webhook配置
+
+用户可以点击“新建配置”按钮，填写所需参数来创建新的Webhook配置。建议在保存前进行测试，确保配置正确。

+
+## 其它
+
+### 监控告警自动关闭
+
+对于任务实例运行失败的监控告警，在运维中心对实例进行处置后恢复成功，比如手动置成功或者重跑实例后成功等，会将对应的告警事件自动置为关闭，不需要人工去关闭。
+
+### Webhook告警的安全设置
+
+钉钉等IM，对Webhook推送告警会有一定的安全设置，通过“自定义关键词”，新增配置上“云器”这个关键词即可。

+
+## 概述
+
+本文档介绍如何通过 Claude Desktop 和云器 Lakehouse MCP Server 实现多云多环境的统一管理，为企业级用户提供简单、高效的数据湖仓管理体验，实现全链路的自然语言对话方式。
+
+```
+我有哪些Lakehouse环境？
+帮我看下生产环境的每个实例里都有哪些workspaces
+帮我切换到腾讯云上海生产环境
+我当前的上下文是？
+有哪些workspaces？
+帮我切到test_ws
+我有哪些计算集群和schema？
+帮我切到DEFAULT
+```
+
+## 使用场景
+
+在企业数字化转型过程中，常见以下多环境管理挑战：
+
+* **多云部署**：同时使用阿里云、腾讯云、AWS等不同云厂商
+* **环境隔离**：开发、测试、生产环境需要独立管理
+* **地域分布**：上海、北京、广州等不同地域的数据中心
+* **资源切换**：需要频繁在不同环境间切换进行运维
+
+传统方式需要登录多个控制台，操作复杂且容易出错。本方案提供了统一的解决方案。
+
+## 技术架构

+      "workspace": "quick_start",
+      "schema": "mcp_demo"
+    },
+    "tencent_shanghai_prod": {
+      "service": "ap-shanghai-tencentcloud.api.clickzetta.com", 
+      "workspace": "quick_start",
+      "schema": "mcp_demo"
+    },
+    "aws_north-1_prod": {
+      "service": "cn-north-1-aws.api.clickzetta.com",
+      "workspace": "quick_start", 
+      "schema": "public"
+    }
+  }
+}
+```
+
+### 步骤2：启动Claude Desktop
+
+安装并启动Claude Desktop，确保已配置云器 MCP Server。

+# 多表离线同步任务
+
+## 功能概述
+
+多表离线同步任务是云器 Lakehouse Studio 提供的批量数据同步能力，支持将源端数据库的整库或多张表以周期调度的方式同步到 Lakehouse 中。与多表实时同步任务不同，多表离线同步采用定期全量同步的方式，适合数据时效性要求相对不高、数据更新具有周期性特征的场景。
+
+## 适用场景
+
+多表离线同步任务适用于以下场景：
+
+* **整库迁移**：需要将源端数据库的所有表批量同步到 Lakehouse，减少逐表配置的工作量
+* **周期性数据更新**：源端数据按固定周期（如每天、每小时）批量更新，无需保持实时同步
+* **分库分表合并**：需要将多个分库分表的数据合并同步到统一的目标表
+* **定期数据校准**：通过周期性全量同步确保目标端数据与源端保持一致
+* **资源优化**：在数据时效性要求不高的情况下，通过离线同步降低资源消耗。
+
+## 功能特性
+
+### 支持的数据源
+
+**来源端**
+* MySQL
+* PostgreSQL
+* SQL Server
+* Aurora MySQL
+* Aurora PostgreSQL
+* PolarDB MySQL
+* PolarDB PostgreSQL

+
+### 同步模式
+
+1. **整库镜像**：同步源端整个数据库的所有表到目标端。
+2. **多表镜像**：选择源端多张表同步到目标端，保持表结构独立。
+3. **多表合并**：将多个源表（如分库分表）合并同步到一张表或多张目标表。
+
+### 核心能力
+
+* **自动建表**：目标端表不存在时自动创建，支持主键表和非主键表，支持灵活使用参数来定制目标端表的命名。
+* **Schema变更适配**：支持源端表结构变化时自动同步到目标端（可选）。
+* **灵活的写入模式**：支持覆盖写入（overwrite）、更新写入（upsert）等多种写入模式。
+* **并发控制**：支持配置分组策略和并发度，以优化同步性能并灵活控制对源端的压力。
+* **调度管理**：基于Cron表达式的灵活调度配置，可与其他任务节点统一编排。

+1. 选择目标workspace（数据空间）
+2. 配置目标命名空间（Schema）
+
+#### 命名空间规则
+
+系统提供三种命名规则：
+
+* **镜像来源**：保持与源端Schema名称一致
+* **指定选择**：手动选择一个已存在的目标Schema
+* **自定义**：使用规则表达式自定义目标Schema名称
+
+**规则表达式说明**
+
+* 支持使用变量：
+
+  * `{SOURCE_DATABASE}`表示源端数据库名称。
+
+* 支持使用自定义任务参数：
+
+  * `比如${bizdate}`等。任务参数的使用详见：[任务参数](task_param.md)
+
+* 示例：`{SOURCE_DATABASE}_${bizdate}`
+
+#### 目标表命名规则
+
+配置目标表的命名规则：
+
+* **镜像来源**：保持与源端表名一致
+* **自定义**：使用规则表达式自定义目标表名
+

+
+  * `{SOURCE_DATABASE}`表示源端数据库名称，`{SOURCE_SCHEMA}`表示源端Schema名称，`{SOURCE_TABLE}`表示源端表名。
+
+* 支持使用自定义任务参数：
+
+  * `比如${bizdate}`等，任务参数的使用详见：[任务参数](task_param.md)
+
+* 示例：`{SOURCE_DATABASE}_{SOURCE_TABLE}_${bizdate}`
+
+#### 分区配置（可选）
+
+如需创建分区表，可配置：
+
+* 是否创建为分区表
+* 分区字段选择
+* 分区值表达式
+
+### 第四步：配置映射关系
+
+![](/.topwrite/assets/image_1763375076182.png =680)
+
+#### 查看同步对象
+
+系统会展示所有配置的同步对象及其映射关系：
+
+* 左侧显示源端表列表
+* 中间显示字段级映射详情
+* 右侧显示目标表的完整路径
+
+#### 字段映射
+
+* 系统自动识别主键（标记为PK）
+* 展示字段类型映射关系
+* 支持查看每个表的详细字段映射
+
+统计信息会显示：
+
+* 映射成功的对象数量
+* 映射失败的对象数量（如有）
+
+### 第五步：配置同步规则
+
+#### 来源数据规则
+
+**来源数据删除字段**
+
+* 继续同步，删除的字段写入Null空值
+
+**来源数据新增字段**
+
+* 自动适配，在目标表新增字段
+
+**来源数据删除表**
+
+* 自动适配，继续同步，忽略已删除的表
+
+#### 分组策略
+
+控制同步任务的分组和并发执行：
+
+**智能分组**
+
+* 系统根据表大小等特征自动分组
+
+**静态分组**
+
+* 按固定的表数量进行分组
+* 可配置单个分组中的表个数
+
+  ![](/.topwrite/assets/image_1763375092075.png =680)
+
+#### 并发控制
+
+**单分组中表个数**
+
+* 在静态分组模式下手动指定
+* 控制单个分组包含的表数量
+* 默认值：4
+
+**单分组中源端最大连接数**
+
+* 限制单个分组对源端的最大并发连接数
+* 默认值：4
+
+**并发执行的分组数量**
+
+* 可同时执行的分组数量
+* 默认值：2
+
+> **性能调优建议**：并发度过高可能对源端数据库造成压力，建议根据源端数据库性能进行合理配置。
+
+#### 数据写入模式
+
+针对不同表类型配置写入策略：
+
+**非主键表写入模式**
+
+* **覆盖写入（overwrite）**：每次同步清空目标表后写入新数据
+
+**主键表写入模式**
+
+* **覆盖写入（overwrite）**：每次同步清空目标表后写入新数据
+* **更新写入（upsert）**：基于主键进行插入或更新操作
+
+### 第六步：任务调试（可选）
+
+完成任务配置并保存后，会进入任务概览页面，如下图：
+![](/.topwrite/assets/image_1763375133438.png =680)
+
+页面右上角的「运行」按钮提供了调试运行功能，可用于验证数据源和任务配置是否正确。触发运行后，可在页面右下角的「运行历史」中查看运行详情。
+
+> 请特别注意，为了控制验证的同步时长，在运行时，系统自动增加了对源端每张表默认只抽取 1000 条数据的限制（也可以手动调整，最多 10000 条）。如果要全量同步所有的数据，请参考后续步骤配置周期定时调度。
+
+### 第七步：配置调度属性
+
+![](/.topwrite/assets/image_1763375144107.png =680)
+
+点击「调度」按钮，可以配置任务的周期调度规则：
+
+1. **调度周期**：按需选择周期调度的频次，比如每天调度、每小时调度等
+
+2. **调度周期配置**：
+   1. 支持小时、天、周、月等多种周期。
+   2. 可使用可视化配置（系统会自动转化为 Cron 表达式）。
+
+3. **生效日期和失效日期**：设置任务调度的起止日期
+
+4. **依赖配置**：设置任务的上下游依赖关系（可选）
+
+5. **其它配置**：实例信息等配置，和普通任务的周期调度配置一样。
+
+### 第八步：提交任务
+
+![](/.topwrite/assets/image_1763375154481.png =680)

+* 告警粒度：以目标表为单位，每张失败的表独立触发告警
+* 支持配置告警接收人和通知方式
+
+## 注意事项
+
+### 权限要求
+
+* **源端权限**：在数据源中配置的账号需要具备读取源端数据库元数据和表数据的权限（SELECT 权限）。
+* **目标端权限**：任务的负责人需要具备在目标端 Lakehouse 创建表和插入数据的权限（CREATE、INSERT 权限）。
+
+### 性能考虑
+
+1. **源端压力**：合理配置并发度，避免对源端数据库造成过大压力。
+2. **初始化时间**：首次执行时需要初始化所有同步对象，可能耗时较长。
+3. **表数量限制**：建议单个任务同步的表数量控制在合理范围，过多表可能影响任务执行效率。
+
+### 数据一致性
+
+1. **覆盖写入模式**：采用覆盖写入时，每次执行会完全刷新目标表数据。
+2. **更新写入模式**：采用upsert模式时，基于主键进行增量更新。
+3. **源端数据变化**：离线同步采用定期全量同步，两次同步间隔期间的数据变化会在下次同步时体现。
+
+### Schema Evolution限制
+
+启用Schema Evolution功能时需注意：
+
+* 不支持修改主键字段（Lakehouse主键表限制）
+* 字段类型修改仅支持同类型扩展（如 int8 → int16 → int32 → int64）
+* 跨类型转换（如 int → double）不支持
+* 建议在源端Schema相对稳定时使用此功能
+
+### 最佳实践
+
+1. **任务粒度**：根据业务关联性和同步需求合理划分任务粒度
+2. **调度时间**：选择源端数据库压力较小的时间窗口执行
+3. **测试验证**：使用"运行"功能进行小批量数据测试后再正式调度
+4. **监控配置**：及时配置告警规则，确保同步异常时能快速感知
+5. **定期检查**：定期查看"表自动变更记录"，了解Schema变更情况

+### 数据库权限配置
+
+同步不同类型数据源的变更事件时，需要在相应数据源服务端配置好适当的权限才能保证数据的正常同步。尽管直接分配一个管理员或超级用户的权限足够保证任务正常运行，但通常会希望能够最小化权限需要分配给同步数据的用户的权限。各操作步骤需要的具体权限配置说明如下。
+
+#### PostgreSQL
+
+请注意，在执行赋权SQL语句时，**确保执行账号自身具备可以授权的权限，建议使用管理员账号**。为了确保任务顺利运行，**建议将下述所有场景的授权均执行一遍**。
+
+**场景：配置任务（获取元数据：schema列表、table列表、table字段列表**）
+
+所需权限：
+
+```
+SELECT（information_schema和需要获取详情的table上）
+```
+
+授权方式
+
+* 赋予某个角色读取information\_schema的权限：
+  ```
+  GRANT SELECT ON TABLE information_schema.tables TO role_name; 
+  ```
+
+* 赋予某个角色读取某张表的权限：
+  ```
+  GRANT SELECT ON TABLE your_schema.your_table TO role_name;
+  ```
+
+**场景：同步WAL日志**
+
+所需权限
+
+```
+REPLICATION
+LOGIN
+```
+

+
+```
+SELECT（需要同步的table上）
+```
+
+授权语句
+
+* 赋予某个角色读取某张表的权限：
+  ```
+  GRANT SELECT ON TABLE table_name TO role_name; 
+  ```
+
+* 赋予某个角色读取schema下所有表的权限：
+  ```
+  GRANT SELECT ON ALL TABLES IN SCHEMA schema_name TO role_name;
+  ```
+
+**场景：变更数据同步，创建publication**
+
+所需权限
+
+```
+CREATE（需要创建publication的database上）
+SELECT（需要添加到publication的table上）
+```
+
+授权语句
+
+* 赋予CREATE权限
+  ```
+  GRANT CREATE ON DATABASE your_database TO role_name;
+  ```
+
+#### MySQL
+
+请注意，在执行赋权SQL语句时，**确保执行账号自身具备GRANT OPTION权限，建议使用超管账号比如root**。为了确保任务顺利运行，**建议将下述所有场景的授权均执行一遍**。
+
+**使用场景：配置任务（获取元数据：database列表、table列表、table字段列表**）
+
+所需权限
+
+```
+SHOW DATABASES 
+SHOW TABLES（或者直接赋予更通用的SELECT权限也可） 
+SELECT
+```
+
+授权语句
+
+* 赋予用户查询 database 列表的权限：
+  ```
+  GRANT SHOW DATABASES ON *.* TO 'username'@'host'; 
+  ```
+
+* 赋予用户查询 table 列表和 table 详情的权限（SELECT包含了SHOW TABLES的权限）：
+  ```
+  GRANT SELECT ON database_name.table_name TO 'username'@'host';
+  ```
+
+**使用场景：基于binlog日志同步变更数据**
+

+GRANT SELECT, RELOAD, SHOW DATABASES, REPLICATION SLAVE, REPLICATION CLIENT ON . TO 'username'@'host';
+```
+
+**使用场景：同步历史全量数据**
+
+所需权限
+
+```
+SELECT
+```
+
+授权语句
+
+* 赋予用户查询 table 的权限：
+
+  ```
+  GRANT SELECT ON database_name.table_name TO 'username'@'host';
+  ```
+
+## 任务创建
+
+### 操作入口
+
+在任务开发界面，点击新建操作，选择“多表实时同步”任务类型。
+
+![](.topwrite/assets/image_1742960426271.png =308)
+
+### 主要步骤
+
+创建多表实时同步任务，大致分为四个步骤：
+
+1. 配置数据类型，选择从源端什么数据源同步到目标端什么数据源。
+2. 配置同步任务类型，当前区分为整库镜像实时同步、多表镜像实时同步和多表合并实时同步三种模式。
+3. 配置需要同步的对象范围，包含来源、目标。
+4. 配置一些高阶的同步规则，比如对于新增表和字段变更的处理逻辑等。
+
+### 配置数据类型
+
+配置多表实时同步任务，首先选择需要同步的来源数据和目标端数据的类型。当前支持的来源数据源类型如下：
+
+![](/.topwrite/assets/image_1762748306754.png =680)
+
+### 选择同步模式
+
+目前支持三种任务同步模式，请按需选择：
+
+* 整库镜像：用于将源端，所有库表的数据，镜像同步到目标端的场景，此种方式以数据库为粒度进行配置，会自动适配库中新增表、自动同步。
+* 多表镜像：用于将源端，选定的库表数据，镜像同步到目标端的场景。此种方式以表粒度进行配置，支持自动感知字段个数的新增和删除的变化。
+* 多表合并：用于将源端分库分表的数据合并写入同一张目标表的场景。
+
+  ![](/.topwrite/assets/image_1762757109125.png =680)
+
+#### 多表镜像
+
+**来源配置**
+
+* 选择数据源
+
+  * 对于多表镜像同步，请选择一个数据源。如果这里不展示，请新建一个数据源，详见 [数据源配置](config-datasource.md)。
+  * 请确保数据源中的账号具备足够的权限，详见下文的权限说明。
+
+* 配置读取模式
+
+  * MySQL 当前只支持 BINLOG 模式。
+  * PostgreSQL 当前只支持 WALs 模式。
+
+* 选择同步对象
+
+  * 先选择需要同步的库，再选择需要同步的表。
+  * 页面提供批量配置的功能，基于配置模板，按照格式要求填写配置文件、上传后，页面会按照文件中给定的内容来选中需要同步的对象，选中后可以按需再进行微调。请注意删除模板文件中的注释说明。
+
+* 配置槽位（slot）
+
+  * 仅PostgreSQL需要配置，槽位（slot）指PostgreSQL 的 replication slot，详见 [说明文档](https://www.postgresql.org/docs/9.4/catalog-pg-replication-slots.html)。
+  * 每个数据库都需要配置一个槽位。目前支持decoderbufs和pgoutput两种插件类型。
+  * 可以选择已存在的槽位进行使用；或者在页面页面来操作新建，在新建窗口的下方区域的创建语句，可按需修改。点击确定后进行创建。在数据源中配置的用户名必须具备创建slot的权限，否则会创建失败，详见下文的权限说明。
+  * 特别注意，不同任务不要复用同一个槽位。任务启动时，如果槽位被其它在运行中的任务占用，会启动失败。如果其它任务处在停止状态，因槽位中的数据会被共享消费使用，位点是被共享的，新任务消费的增量数据，同步到目标端的表数据可能会不全。
+
+**目标配置**
+
+目标端目前只支持写入到Lakehouse。
+
+* 目标数据源
+  * 默认是当前工作空间对应的Lakehouse数据源，不需修改。
+* 命名空间规则
+  * 当前仅支持选择特定的命名空间，后续会扩展支持按照源端进行镜像命名或者自定义命名。
+  * 按需选择特定命名空间（工作空间）即可。
+* 目标表命名规则
+  * 当前仅支持镜像来源名字，后续会扩展支持添加前缀或者自定义命名规则。
+* 计算集群
+  * 选择工作空间下可用的集群，推荐使用AP类型的集群。
+
+**预览配置**
+
+* 完成上述源端和目标端配置后，可以预览同步表和字段的映射关系。如果有需要修改，请返回上一步进行调整。
+
+**同步规则**
+
+* 同步规则中，可以配置Schema Evolution规则，来定义源端表和字段变化后的处理行为，以及选择需要处理的源端变更消息类型等。请按需配置。
+
+  ![](/.topwrite/assets/image_1762757310752.png =680)
+
+
+#### 整库镜像
+
+配置方式和多表镜像基本类似，请参考上文。最大的区别在于选择源端库表时，限制只让选择库，不可以选择具体的表。
+
+#### 多表合并
+
+**来源配置**
+
+* 选择数据源
+  * 同上，多表镜像同步类似
+* 配置读取模式
+  * 同上，多表镜像同步类似
+* 选择同步对象
+  多表合并同步，会使用“虚拟表”作为中间的过度承接，需要在配置时候指定使用什么虚拟表来承接哪些对象的数据。支持两种方式进行配置
+  * 方式一：基于规则配置，通过正则匹配进行筛选，比如选出以abc开头的所有表，在正则表达式中填写 ^abc 即可
+  * 方式二：基于文件批量配置，按照模板中格式要求填写配置文件、上传后，页面会按照文件中给定的内容来选中需要同步的对象，选中后可以按需再进行微调。请注意删除模板文件中的注释说明
+
+**目标配置**
+
+* 同上，和多表镜像同步类似
+
+**预览配置**
+
+* 同上，和多表镜像同步类似
+
+**同步规则**
+
+* 同上，和多表镜像类似
+
+### 任务高阶参数
+
+在多表实时同步任务的「参数」区域，可以设定一些高阶参数来控制同步任务的资源消耗等。
+
+> 这些参数强烈建议使用默认取值即可，非必要不修改。如需要调整，建议事先咨询服务您的技术支持人员后再修改。
+
+![](.topwrite/assets/image_1756200956528.png =680)
+
+具体可以设定的高阶参数的名称、含义和默认取值如下。这些参数默认不建议调整，如果有使用需要，建议先联系技术支持人员确认后再进行设定、更改：
+
+| 参数名称                                        | 参数含义                | 参数取值         |
+| ------------------------------------------- | ------------------- | ------------ |
+| step1.taskmanager.memory.process.size       | 增量同步任务计算进程使用的总内存大小  | 默认值：1600m    |
+| step1.taskmanager.memory.task.off-heap.size | 增量同步任务计算进程使用的堆外内存大小 | 默认值：256m     |
+| step2.taskmanager.memory.process.size       | 全量同步任务计算进程使用的总内存大小  | 默认值：2000m    |
+| lh.table.cz.common.output.file.max.size     | 全量同步写表时切分出单个文件的大小   | 默认值：33554432 |
+| lh.table.cz.common.output.enable.rotate     | 全量同步写表时是否切分文件       | 默认值：true     |
+| pod.limit.memory                            | 提交同步任务的客户端使用内存上限    | 默认值：1Gi      |
+
+### 提交
+
+点击提交按钮，可将任务提交到生产环境执行。**请注意，任务提交后默认不会自动启动，需要手动启动**。
+
+## 任务运维
+
+### 启动任务
+
+进入任务详情页，可以操作启动任务，请按需选择以下启动方式之一。任务启动后，初始化阶段，根据表的数量不同，可能会消耗几分钟或者更久的时间，请耐心等待。
+
+**启动方式**
+
+* 无状态启动（仅在任务首次启动才支持）：完整同步所有数据，先全量同步，再启动增量同步。
+* 从上次保存状态恢复（仅对停止后的任务再次启动支持）：如果上次同步被停止，会从停止的位置断点续传。
+* 自定义起始位置：从给定的位点进行同步，可以用于数据回刷。对任务中配置的所有表全统一生效。
+  * MySQL：选择指定文件启动或者指定时间启动。在页面监控区域可以获取到上次文件位置。
+  * PostgreSQL：指定LSN取值，在下文的实例监控中可以查看到最新的LSN取值。
+
+**全量同步**
+
+* 通过此配置控制在增量同步前，是否先进行全量的数据同步。请注意，如果选择不进行全量同步，停止任务后重启可以再选择全量同步。
+* 最大并发数：如果在启动任务时，选择了先进行全量数据同步，可以通过此参数来控制进行全量数据同步的并发子任务个数。同步任务会建立对应个数的JDBC连接到源端数据库。参数数值越大，理论同步速度会更快（在打满源端负载之前），但对源端的压力也会越大。
+
+### 实例监控
+
+#### 阶段监控
+
+任务启动后，会经历初始化、全量同步、增量同步三个阶段。可在实例监控区域查看这三个阶段的运行状态。

+
+### 停止任务
+
+停止任务会停止任务中正在进行的全量同步和增量同步。停止时会自动保存增量同步的位点状态。
+
+* 如果停止时表处在全量同步阶段，重启后，未完全全量同步的表，会重新进行一次全新的全量同步。
+* 如果停止时表处在增量同步阶段，重启后，默认会从同步停止的位点继续同步。
+
+### 下线任务
+
+下线任务属于高危操作，任务下线后，不会保存当前同步的位点。如果再次上线并启动任务，会重新开始同步数据。
+
+* 下线不会清理已经同步到目标端的数据，但会清理中间过程的缓存数据和位点信息。
+* 重新同步不会重新建表，全量数据同步会对于老的表进行覆盖写入，增量同步会对目标表做merge into的更新。
+
+## 已知局限
+
+* Schema Evolution，暂不支持变更字段类型、不支持自动新增表。
+
+* 多表实时同步任务中，源端不同库表中若存在主键相同的数据，同步结果会出现异常。
+
+* MySQL同步，尚不支持的字段类型：
+
+  | 字段类型 | 同步后行为 |
+  | ---- | ----- |
+  | year | 取值不对应 |
+
+* PostgreSQL同步，尚不支持的字段类型：
+
+  | 字段类型     | 同步后行为          |

+# 多表实时同步任务完整指南
+
+## 功能概述
+
+多表实时同步任务，可以实现对源端库表进行全量同步和增量同步。其中增量同步，主要是基于对数据库变更消息进行处理来实现。多表实时同步任务是一个常驻任务，可达到秒级的端到端数据时效性。多表实时同步，支持两种同步类型和两种同步模式：
+
+### 两种同步类型：全量同步和增量同步
+
+* 其中全量同步为可选步骤，在启动实时同步任务时可以选择全量同步，也可以不选择。
+* 如果选择了全量同步，系统会在启动增量同步时，也同时进行全量同步数据。全量同步的数据会写入到临时表，然后进行merge合并操作。全量同步完成后，会自动继续增量同步，不需要人为干预。
+* 全量同步，基于JDBC协议，连接到源端抽取数据，会对数据库有较大的读取压力。
+* 增量同步，基于数据库变更消息（比如MySQL的binlog），来解析其中内容，同步写入到目标端。对于数据库的压力主要是连接串的压力，相比全量同步，压力会小很多。
+
+### 两种同步模式：多表镜像同步和多表合并同步
+
+这两种模式的区别在于源端的表如何写入到目标端。
+
+* 多表镜像同步，目标端的表和源端的表是一一对应的。
+* 多表合并同步，支持把源端多张表合并写入到目标端一张表中。这种模式适合于源端是分库分表场景。多表合并同步，要求源端表的字段结构完全一致，或者基本一致。
+
+## 原理介绍
+
+### 流程原理
+
+主要步骤如下：
+
+* 启动增量同步，将源端变更数据，同步写入到目标表中。
+
+* 进行全量同步，将数据存量数据，同步到临时表，此过程增量同步不停止。
+
+* 全量同步完成后，将临时表的数据合并到目标表中，此过程会先停止增量同步，暂停消费源端数据库的变更。
+
+* 合并完成后，恢复增量同步。
+
+## 使用和运维指南
+
+### 常规使用：在进行实时同步前，对源端数据库需要进行哪些参数设置和权限准备？
+
+对源端数据库，需要进行必要的参数和权限配置，以确保数据库变更日志工作正常和同步任务具备足够权限能够正常获取到数据，
+
+#### 数据库参数配置
+
+**PostgreSQL**
+
+注意：修改以下参数需要重启Postgresql Server后生效。
+
+|                            |                                                                                                                                                                             |           |
+| -------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- |

+#### 数据库权限配置
+
+同步不同类型数据源的变更事件时，需要在相应数据源服务端配置好适当的权限才能保证数据的正常同步。尽管直接分配一个管理员或超级用户的权限足够保证任务正常运行，但通常会希望能够最小化权限需要分配给同步数据的用户的权限。各操作步骤需要的具体权限配置说明如下。
+
+**PostgreSQL**
+
+请注意，在执行赋权SQL语句时，确保执行账号自身具备可以授权的权限，建议使用管理员账号。为了确保任务顺利运行，建议将下述所有场景的授权均执行一遍。
+
+**使用场景：配置任务（获取元数据：schema列表、table列表、table字段列表**）
+
+所需权限：
+
+> SELECT（information\_schema和需要获取详情的table上）
+
+授权方式
+
+* 赋予某个角色读取information\_schema的权限：
+
+  ```SQL
+    GRANT SELECT ON TABLE information_schema.tables TO role_name; 
+  ```
+
+* 赋予某个角色读取某张表的权限：

+
+### 常规使用：如何配置和运行实时同步任务同步？
+
+通过以下步骤，按序操作：
+
+1. 在任务开发中配置同步任务，选择合适的镜像同步/多表合并同步模式，选定同步对象和正确的目标schema。
+2. 保存任务配置内容。
+3. 在调度配置中，选择合适的同步型集群，作为任务的资源，保存。
+4. 提交任务到运维中心。
+5. 在运维中心，操作启动任务。特别注意按需选择是否需要进行全量同步（此选项仅在任务提交上线后第一次启动时可以选择）。
+
+### 常规使用：配置同步任务，如何选择源端数据对象？
+
+* 多表镜像同步模式，源端表的选择相对简单，按照页面指引，否选需要同步的库表即可。
+
+* 多表合并同步模式，相对更加复杂，需要基于“虚拟表”的概念来进行操作。
+
+  * “虚拟表”核心作用是用来定义将源端哪些表同步到一张表中
+  * 新建“虚拟表”时，可以基于数据源、Schema、Table名称，给定筛选条件，来全选需要同步的源端表的范围，然后把这些表，定义成写入到同一张“虚拟表”。
+  * 系统会基于“虚拟表”的命名，在目标端Lakehouse中自动创建出目标表。
+
+### 常规使用：在同步过程中，期待在目标表中额外新增字段来记录来源信息，需要如何配置？
+
+* 可以在任务配置时，开启使用扩展字段功能。
+
+* 扩展字段目前支持设置源端server名称、database名称、schema名称和table名称。
+
+  ![](.topwrite/assets/image_1740314767939.png =680)
+
+### 常规使用：在同步过程中，如果源端表中，不同分库分表里面，存在主键相同记录，需要如何配置同步任务来避免数据写入冲突？
+
+* 可以在任务配置时，开启使用扩展字段功能，并把扩展字段设置为目标表的联合主键。
+
+  ![](.topwrite/assets/image_1740314789823.png =680)
+
+### 常规使用：如果源端的分库分表，表的字段结构基本一致，但又不是完全相同， 部分表多一些字段，如何配置同步任务？
+
+* 使用异构字段合并功能。
+* 在配置虚拟表时，系统会自动校验源端表的字段结构是否完全一致，如果不一致，系统会提示出来，依据提示，选择
+
+### 常规使用：如果任务第一次启动没有选择全量同步，后续想补充进行全量同步，如何操作？
+
+有如下几种方案可以使用：
+
+* 方案一：操作单表进行重新同步。
+
+  * 重新同步，会先把源端表同步到临时表中，然后通过insert overwrite写入到目标表中。
+  * 重新同步不会影响目标表的数据查询。
+
+* 方案二：操作单表进行补数同步，在过滤条件中，给一个能全量拉取到源端表的条件，比如 where 1=1 。
+
+  * 除了给where条件之外，也可以按需选择其它条件进行过滤，比如数据源名称、数据表名称。
+
+* 方案三：把同步任务停止、下线、然后再上线。启动任务时，选择进行全量同步。
+
+  * 停止和下线任务不会删除目标表。
+  * 停止任务，会使得目标表中的数据不再更新，基于目标表查询到的数据不是最新、会有延迟。
+  * 下线任务会清空同步位点等中间信息，无法做到从停止的位置继续续传。重新上线任务、启动后，只能重新开始进行全量同步和增量同步。
+
+### 常规使用：任务启动后，如果想新增更多表进行同步，需要如何操作？
+
+* 编辑任务，添加需要新增的表，保存任务。
+
+* 提交任务发布。
+
+* 在运维中心，操作停止任务、再启动任务。
+
+  * 重启后，会自动同步新增的表的数据。如果任务设定了要全量同步，会执行全量同步；反之只做增量同步。
+
+### 常规使用：分库分表，加减数据源、schema、table，需要如何操作，有什么影响？
+
+* 在任务开发界面，直接编辑即可。
+* 添加对象后，需要保存、提交，提交之后重启任务才能生效。
+* 任务重启后，会开始同步数据，如果任务设定为会全量同步，新增的对象也会自动进行全量同步。
+* 不会影响存量表的同步进度。
+
+### 常规使用：任务启动后，对所有表都进行全量同步耗时较长，如何优先同步重要的表？
+
+* 在正在进行全量同步的重要单表上，使用“优先执行”，会在资源队列中插队、优先处理，进行全量同步。
+
+### 常规使用：任务启动后，如何查看表的全量同步状态和详情？
+
+* 在运维中心，实时同步任务页面，同步对象区域，可以看到表的全量同步状态。
+* 在表的“操作”中，通过“全量同步详情”操作，可以查看全量同步实例的详细情况，包含任务实例的配置、详细日志等详情。
+
+### 常规使用：任务启动后，如何对任务中的特定表进行重新同步，有什么影响？
+
+* 如果需要修复特定表中的数据，选择“重新同步”：
+
+  * “重新同步”操作，会先重新同步源端表中的数据到临时表中，然后通过insert overwrite写入到目标表中，会重写掉目标表中已存在的数据。但不影响该目标表的查询。
+
+* 如果要从源端重新拉取全量数据/部分数据，选择“补数同步”：
+
+  * “补数同步”操作，会按照给定的过滤条件，从源端拉取数据到临时表中，然后delete目标表的相关数据，最后通过merge into的方式写入到目标表。
+
+### 常规使用：如果想暂时停止增量数据同步，需要如何操作？
+
+* 在运维中心的实时同步详情页，点击“停止”按钮，即可停止所有表的增量消息消费、不再进行同步。
+
+  * 注：不需要下线任务。
+
+* 如果想要恢复同步，点击“启动”按钮。
+
+* 点击“启动”按钮后，在弹框中，默认选择“从上次保存状态恢复”即可，系统会自动从上次停止为止续传处理。
+
+* 如果要进行回溯，可选择“自定义起始位置”，给点具体的位点/文件来回追数据。如下图以MySQL为例，请确保填写的binlog位点没有过期失效。
+
+### 常规使用：任务启动后，如何暂停和恢复单表的增量同步？
+
+* 在单边的运维操作菜单中，选择“停止增量同步”，会暂停该表的变更数据的增量同步，不再写入到目标表中。
+
+* 对于暂停增量同步的表，操作“恢复增量同步”，会重新启动该表的变更数据的增量同步，写入到目标表中。
+
+  * 为了保证数据的连续性，在恢复增量同步时，会从源端重新拉取一次全量数据。
+
+### 常规使用：下线实时同步任务有何影响？在什么情况下需要下线任务？
+
+* 下线任务属于相对高危的操作，建议谨慎使用，非必要不使用。
+* 停止实时同步任务、下线掉， 不会清理目标表中的数据、不会删除目标表，但会清理中间过程的缓存数据和位点信息。
+* 如果任务确定不再需要使用，可以下线任务。
+* 如果遇到任务状态异常等偶发情况，期望对任务进行一次修复，可以尝试下线任务后再上线任务。
+* 下线任务、再次上线并启动任务，会重新开始同步数据。重新同步不会重新建表，全量数据同步会对于老的表进行覆盖写入，增量同步会对目标表做merge into的更新。
+
+### 常规使用：如果同步任务中数据表和数据量特别大，做性能调优，可以通过哪些参数来设置？
+
+* 在任务配置中的参数，通常保持默认值即可。
+
+* 如果全量数据特别大，期待加速同步速度，在任务的“配置”中，可以适当调大以下两个参数的取值：
+
+  * step1.taskmanager.memory.process.size，比如设定为4000m（默认：1728m）
+
+  * step1.taskmanager.memory.task.off-heap.size，比如设定为500M（默认：256M）
+
+    ![](.topwrite/assets/image_1740314863947.png =680)
+
+### 紧急运维：任务失败后，遇到无法自行处理的问题，如何配合云器排查？
+
+* 第一时间可通过飞书、电话等方式联系云器技术支持人员，云器方在接收到电话或者飞书信息后会快速做出响应并启动问题处置流程。
+* 由于是OP部署环境，存在网络隔离等原因，需要客户配合获取任务执行日志等信息，以便快速排查解决问题。
+
+### 紧急运维：如果源头突发多张表的流量很大，影响部分重要表的同步消费，如何处理？
+
+* 可以对相对不重要的表，使用“暂停增量同步”功能，暂停该表的变更消息消费，为重要表的同步让出处理资源。
+* 在重要表的变更消费完成后，再回复被暂停表的增量同步。
+
+## 任务监控和告警
+
+### 任务详情运维页面监控指标的含义

+#### 实时数据集成任务中最大延迟监控配置
+
+1. 端到端同步延迟：新建监控规则，在监控事项中选择“多表实时同步延迟”。可以额外增加过滤属性，比如工作空间、任务名称等。如不增加过滤，默认对实例下所有多表实时任务全部监控。

+
+## 常见报错排查
+
+### 增量同步失败
+
+#### Binlog位点过期
+
+* 问题现象
+
+  * 以指定文件和位点的方式启动任务，或者任务停止一段时间后选择从状态恢复启动后任务失败，执行日志中报错：Caused by: java.lang.IllegalStateException: The connector is trying to read binlog starting at Struct{version=1.9.7.Final,connector=mysql,name=mysql\_binlog\_source,ts\_ms=1734071479878,db=,server\_id=0,file=mysql-bin.010937,pos=432041283,row=0}, but this is no longer available on the server. Reconfigure the connector to use a snapshot when needed.
+
+* 可能原因
+
+  * Mysql的binlog通常不会永久保存，会被定期回收，如果指定了一个已经被清理的binlog文件或位点，或者任务停止了很长时间，自动从状态恢复的时候会继续从上次暂停的一个被清理的位点继续消费，则会遇到上述报错，因为对应的binlog数据已经被删除。
+
+* 解决措施
+
+  * 通过`show master status` 查询当前数据库的最新binlog文件和位点：
+
+    ![](.topwrite/assets/image_1740315126085.png =460)
+
+  * 使用结果中的file和position重启同步任务
+
+    ![](.topwrite/assets/image_1740315139248.png =460)
+
+  * 如果需要补回丢失的数据，可以选择相应的表进行重新同步
+
+#### Server-id冲突
+
+* 问题现象
+
+  * 任务启动失败，执行日志中报错：A slave with the same server\_uuid/server\_id as this slave has connected to the master; the first event '' at 4, the last event read from '/home/mysql/log/mysql/mysql-bin.011268' at 90995258, the last byte read from '/home/mysql/log/mysql/mysql-bin.011268' at 90995258. **Error** code: 1236; SQLSTATE: HY000. The 'server-id' in the mysql cdc connector should be globally unique, but conflicts happen now.
+* 可能原因
+
+  * 实时同步任务默认在为每个mysql数据源建立一个连接并分配一个server-id用来同步binlog数据，生成的server-id的范围在5400-6400之间，如果出现上述报错导致任务失败，说明本次任务为这个数据库连接分配的server-id与数据库上的其他同步工具或同步任务发生了冲突。
+* 解决措施
+
+  * 检查同一个数据库实例下是否有其他同步任务或同步工具正在同步binlog数据
+  * 重启同步任务
+
+#### 数据源时区配置错误
+
+* 问题现象
+
+  * 任务启动失败，执行日志中报错：Caused by: org.apache.flink.table.api.ValidationException: The MySQL server has a timezone offset (28800 seconds ahead of UTC) which does not match the configured timezone Etc/GMT+12. Specify the right server-time-zone to avoid inconsistencies for time-related fields.
+
+* 可能原因
+
+  * 数据源中配置的时区（默认东八区，Asia/Shanghai）与数据库配置的时区不一致。
+
+* 解决措施
+
+  * 确认数据库配置的时区，然后修改数据源中配置的时区
+
+#### Binlog事件size超限
+
+* 问题现象
+
+  * 任务运行失败，执行日志中报错Caused by: io.debezium.DebeziumException: log event entry exceeded max\_allowed\_packet; Increase max\_allowed\_packet on master; the first event '' at 58722808, the last event read from '/rdsdbdata/log/binlog/mysql-bin-changelog.004054' at 109251835, the last byte read from '/rdsdbdata/log/binlog/mysql-bin-changelog.004054' at 109251854. Error code: 1236; SQLSTATE: HY000.
+
+* 可能原因
+
+  * 数据库配置的`max_allowed_packet`小于Binlog中的某个事件的size
+  * 数据库binlog文件损坏
+
+* 解决措施
+
+  * 联系dba调整数据库的`max_allowed_packet`参数大小，可调整的上限为1G，生效后重新同步
+  * 如果调整`max_allowed_packet` 参数后仍然无法成功，则binlog文件可能已经损坏，可以重启任务，选择一个更新的点位，即跳过有问题的位点来继续同步增量数据；如果需要补全中间可能缺少的数据，选择需要补全数据的表重新同步全量数据
+
+### 全量同步失败
+
+#### PK长度超限
+
+* 问题现象
+
+  * 全量同步状态失败，执行日志中报错：BulkLoad stream errorcom.dtstack.flinkx.throwable.FlinkxRuntimeException: BulkLoad failed, stream id: bulkload\_stream\_xxx final status\:COMMIT\_FAILED, error msg\:Task lost connection, message: container stopped by AM. Detail CZLH-71006\:Encoded key size 191 exceeds max size 128
+
+* 可能原因
+
+  * 源表中的主键字段总长度过程，超过默认配置的128字节
+  * 同步任务配置中选择了多个扩展字段作为联合主键，如多表合并场景中选择了server\_id、database、schema、table作为联合主键来避免多个表中的主键字段有冲突，扩展后的联合主键总长度超过默认配置的128字节
+
+* 解决措施
+
+  * 修改同步任务，增加配置：
+
+  ```Bash
+    step1.containerized.taskmanager.env.pk_encoded_key_override_size 256step2.containerized.taskmanager.env.pk_encoded_key_override_size 256
+  ```
+
+### 同步任务Failover
+
+#### 与Lakehouse Ingestion Service断连
+
+* 问题现象
+
+  * 任务发生failover，failover详情中有如下信息：java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.lang.RuntimeException: java.io.IOException: Async commit for instance \[270076] workspace \[xsy\_ent] failed. Error detail is\:rpcProxy call hit final failed after max retry reached. at com.dtstack.flinkx.connector.lakehouse.sink.LakeHouseRedisMetaHybridIgsMultiWriter.flushInternal
+
+* 可能原因
+
+  * 通常发生在Lakehouse服务端升级的情况下，数据同步任务与Lakehouse Ingestion Service连接中断
+
+* 解决措施
+
+  * 一般发生在服务升级期间，通常在完成升级后任务会自动恢复
+  * 如果确认服务升级完成，任务还在持续failover，尝试手动重启任务
+  * 如果手动重启任务后任务还是无法恢复正常，需要检查Lakehouse Ingestion Service服务健康状态
+
+#### Binlog事件反序列化失败
+
+* 问题现象
+
+  * 任务发生failover，failover详情中有如下信息：com.github.shyiko.mysql.binlog.event.deserialization.EventDataDeserializationException: Failed to deserialize data of EventHeaderV4
+
+* 可能原因
+
+  * 这个问题通常出现在来源数据库的binlog中突然产生了大量的事件，如发生大量业务数据的更新，或历史数据批量删除等场景，导致同步任务写入端无法在短时间内处理完所有数据，发生反压，同步任务的读取端停止消费binlog数据，同步任务中的binlog client与数据库服务端的连接会被任务超时而中断，或者服务端的处理线程idle过久被回收，都有可能导致同步任务接受到不完整的binlog事件消息，从而导致反序列化失败
+
+* 解决措施
+
+  * 如果流量的增长是短时间的，通常同步任务能够在有限的failover次数内恢复正常
+  * 如果持续长时间出现，可尝试调整mysql配置，调大slave\_net\_timeout和thread\_pool\_idle\_timeout的值，
+  * 临时调整（MySQL实例重启会失效）：
+
+  ```SQL
+    set global slave_net_timeout = 120; -- default 60 secondsset global thread_pool_idle_timeout = 120; -- default 60 seconds
+  ```
+
+  * 永久调整，修改MySQL的配置文件
+
+  ```Bash
+    [mysqld]slave_net_timeout = 120thread_pool_idle_timeout = 120
+  ```
+
+### 表进入黑名单
+
+#### 执行Schema evolution失败
+
+* 问题现象
+
+  *   某张表的状态自动变为停止同步状态，表对象边上的tips看到有`pk column different`、`pk column type mismatch`、`invalid modify column`等错误信息
+
+* 可能原因
+
+  * 来源表结构发生了Lakehouse不支持的变更，包括：
+  * PK字段列表变更，如PK字段重命名，或从原来的一个字段变成两个字段
+  * PK字段类型变更，如将PK字段的类型从bigint改为varchar
+  * 字段类型发生不兼容修改，如从int改为double等
+
+* 解决措施
+
+  * 检查源端表结构，修改为正确的结构
+  * 重新全量同步停止增量同步的表，全量同步完成后相应的增量数据也会继续同步
+
+## 已知局限和注意事项
+
+* 为保证目标端数据写入不出现冲突，仅支持对源端是带主键PK字段的表配置同步，非PK表不支持同步。
+* 在同步任务中会自动创建目标表，为了确保任务运行稳定和数据正确，无特别必要，不要手动去创建表、修改表和删除表。
+* Schema Evolution，支持源端新增字段、删除字段，暂不支持变更字段类型、不支持自动新增表。

+## 🎯 安装部署
+
+### 1️⃣ 下载部署包
+
+下载 `data-diff-n8n-deploy-latest.zip` 并解压到任意目录：
+
+```bash
+# 使用 curl 下载（推荐）
+curl -L -O https://github.com/yunqiqiliang/clickzetta_quickstart/raw/main/datadiff_n8n_clickzetta/data-diff-n8n-deploy-latest.zip
+
+# 或使用 wget 下载（覆盖已有文件）
+wget -O data-diff-n8n-deploy-latest.zip https://github.com/yunqiqiliang/clickzetta_quickstart/raw/main/datadiff_n8n_clickzetta/data-diff-n8n-deploy-latest.zip
+
+# 解压部署包（覆盖模式）
+unzip -o data-diff-n8n-deploy-latest.zip
+cd data-diff-n8n/
+
+# 如果需要交互式确认每个文件的覆盖
+# unzip data-diff-n8n-deploy-latest.zip
+```
+
+### 2️⃣ 检查端口（推荐）
+
+在部署前检查所需端口是否可用：
+
+**Windows**:
+```cmd
+check-ports.bat
+```
+
+**macOS/Linux**:
+```bash
+./check-ports.sh
+```
+
+检查脚本会自动检测所有必需端口是否可用。如果发现端口冲突，可以：
+
+1.  停止占用端口的服务
+2.  或在运行 `./deploy.sh setup` 后编辑 `.env` 文件修改相应端口
+
+### 3️⃣ 初始化配置
+
+**Windows**:
+```cmd
+deploy.bat setup
+```
+
+**macOS/Linux**:
+```bash
+./deploy.sh setup
+```
+
+此命令会：
+
+* 创建 `.env` 配置文件
+* 自动生成安全密码
+* 准备部署环境
+
+⚠️ **重要提醒**：
+
+*   初始化完成后，**请立即查看并保存** `.undefined` **文件中的密码**。
+
+*   自动生成的密码包括：
+
+  *   PostgreSQL 数据库密码（POSTGRES_PASSWORD）
+  *   N8N 基本认证密码（N8N_BASIC_AUTH_PASSWORD，用户名默认为 admin）
+  *   Grafana 管理员密码（GRAFANA_PASSWORD，用户名默认为 admin）
+
+* 请妥善保管这些密码，丢失后将无法恢复
+
+### 4️⃣ 启动服务
+
+#### 首次部署
+
+**Windows**:
+```cmd
+deploy.bat init
+```
+
+**macOS/Linux**:
+```bash
+./deploy.sh init
+```
+
+启动时间取决于是否需要下载镜像：
+
+* **首次启动**：10-20 分钟（需要下载所有 Docker 镜像，约 2GB）
+* **后续启动**：2-3 分钟（镜像已在本地）
+
+启动过程中会：
+
+1. 自动拉取所有必需的 Docker 镜像（6个服务）
+2. 创建并初始化 PostgreSQL 数据库
+3. 配置 Grafana 仪表板
+4. 启动所有服务并进行健康检查
+
+#### 日常使用
+
+**Windows**:
+```cmd
+deploy.bat start
+```
+
+**macOS/Linux**:
+```bash
+./deploy.sh start
+```
+
+`start` 命令直接启动所有服务，适合日常使用。
+
+💡 提示：
+
+* 使用 `deploy.sh status` 查看启动进度
+* 使用 `deploy.sh logs` 查看服务日志
+
+## 🎉 访问服务
+
+部署完成后，可以通过以下方式访问服务：
+
+| 服务            | 访问地址                                  | 说明                 |
+| --------------- | ----------------------------------------- | -------------------- |
+| 🏠 主页         | [http://localhost](http://localhost/)               | 系统概览和快速导航     |

+:-: ![](.topwrite/assets/image_1756882465416.png =821)
+
+登录凭据请查看 `.env` 文件中的密码。
+
+💡 **提示**：
+
+* 所有服务均通过 **80 端口统一访问**（已自动配置 Nginx 反向代理）。
+* 由于配置了子路径，**不支持直接通过服务端口访问**（如 N8N 的 5678 端口）。
+* **远程访问**：部署在服务器时，将 `localhost` 替换为服务器 IP 地址（如 `http://172.17.1.220`）。
+* **修改端口**：如需修改 80 端口，请编辑 `.env` 文件中的 `HTTP_PORT` 后重启服务。
+
+## 🛠️ 日常操作
+
+### 查看服务状态
+
+```bash
+# Windows
+deploy.bat status
+
+# macOS/Linux
+./deploy.sh status
+```
+
+### 查看日志
+
+```bash
+# 查看所有服务日志
+deploy.bat logs
+
+# 查看特定服务日志
+deploy.bat logs n8n
+```
+
+### 停止服务
+
+**Windows**:
+```cmd
+deploy.bat stop
+```
+
+**macOS/Linux**:
+```bash
+./deploy.sh stop
+```
+
+### 重启服务
+
+**Windows**:
+```cmd
+deploy.bat restart
+```
+
+**macOS/Linux**:
+```bash
+./deploy.sh restart
+```
+
+### 其他命令
+
+**完全停止（移除容器）**：
+
+```bash
+./deploy.sh stop-all
+```
+
+**完整重启（包含初始化检查）**：
+
+```bash
+./deploy.sh restart-full
+```
+
+💡 提示：
+
+* 日常操作使用 `start`、`stop`、`restart` 即可。
+* `stop` 只停止容器，`stop-all` 会移除容器。
+* `init` 和 `restart-full` 包含完整的初始化检查，适合故障排除。
+
+## 📝 配置说明
+
+编辑 `.env` 文件可以修改：
+
+* **端口配置**：默认通过 80 端口统一访问
+* **密码设置**：修改各服务的访问密码
+* **资源限制**：调整 API 工作进程数等
+* **公共 URL**：配置 N8N 的外部访问地址
+
+示例：
+
+```env
+# 修改统一入口端口（默认 80）
+HTTP_PORT=8080
+
+# 配置 N8N 公共 URL（用于生成邀请链接等）
+N8N_PUBLIC_URL=http://172.17.1.220/n8n
+
+# 修改 API 工作进程数（默认 4）
+API_WORKERS=8
+
+# 修改数据库端口（如果需要外部访问）
+POSTGRES_PORT=5433
+```
+
+## 🔧 诊断工具
+
+### check-env-vars.sh 使用指南
+
+当遇到数据库连接或认证问题时，使用此工具进行诊断：
+
+```bash
+./check-env-vars.sh
+```
+
+**适用场景**：
+
+* N8N 或 API 服务报告 "password authentication failed"
+* 需要验证环境变量是否正确传递给容器
+* 检查容器内实际使用的配置值
+
+**功能说明**：
+
+1. 显示 `.env` 文件中的配置
+2. 展示 Docker Compose 解析后的环境变量
+3. 检查运行中容器的实际环境变量
+4. 测试数据库连接是否正常
+
+**示例输出**：
+
+```bash
+=== 环境变量检查工具 ===
+
+1. 检查 .env 文件内容:
+POSTGRES_PASSWORD 设置: VUEk30jlqj6rd48U
+
+2. Docker Compose 解析后的环境变量:
+[显示各服务的环境变量配置]
+
+3. 运行中容器的实际环境变量:
+[显示容器内的实际环境变量]
+
+4. 测试数据库连接:
+✓ 可以使用 .env 密码连接
+```
+
+如果发现密码不匹配，通常需要清理并重新部署：
+
+```bash
+./deploy.sh clean
+./deploy.sh setup
+./deploy.sh init
+```
+
+## 🔄 更新部署
+
+当有新版本发布时，可以使用以下步骤更新：
+
+### 保留配置的更新
+
+```bash
+# 1. 备份当前配置（推荐）
+cp .env .env.backup
+
+# 2. 下载最新版本（覆盖旧文件）
+curl -L -O https://github.com/yunqiqiliang/clickzetta_quickstart/raw/main/datadiff_n8n_clickzetta/data-diff-n8n-deploy-latest.zip
+
+# 3. 解压并覆盖（除了 .env 文件）
+unzip -o data-diff-n8n-deploy-latest.zip -x "data-diff-n8n/.env"
+
+# 4. 重启服务
+./deploy.sh restart
+```
+
+### 完全覆盖更新
+
+```bash
+# 警告：这会覆盖所有文件，包括配置
+unzip -o data-diff-n8n-deploy-latest.zip
+```
+
+💡 **提示**：
+
+* `-o` 参数表示自动覆盖所有文件，不询问。
+* `-x` 参数可以排除特定文件不被覆盖。
+* 建议总是先备份 `.env` 文件，其中包含您的密码配置。
+
+## 🚨 故障排除
+
+### 端口被占用
+
+默认使用 80 端口作为统一入口。如果 80 端口被占用：
+
+1. 编辑 `.env` 文件，修改 `HTTP_PORT`：
+
+   ```env
+   HTTP_PORT=8080  # 或其他可用端口
+   ```
+
+2. 重启服务：
+
+   ```bash
+   ./deploy.sh restart
+   ```
+
+3. 访问新端口：
+
+   ```bash
+   http://localhost:8080
+   ```
+
+### Docker 未运行
+
+确保 Docker Desktop 已启动并正在运行。
+
+### 服务无法访问
+
+1. 使用 `deploy.bat status` 检查服务状态
+2. 使用 `deploy.bat logs` 查看错误日志
+3. 确保防火墙允许相应端口访问
+
+### 数据库初始化错误
+
+如果看到以下错误：
+
+* `数据库初始化失败：datadiff 数据库不存在`
+* `数据库表未正确创建`
+* `password authentication failed for user "postgres"`
+* `relation "data_diff_results.comparison_summary" does not exist`
+
+**原因**：
+
+1.  PostgreSQL 数据卷保留了旧的配置或密码。
+2.  数据库初始化脚本未能执行（PostgreSQL 只在首次创建数据卷时执行 `/docker-entrypoint-initdb.d/` 中的脚本）。
+
+**解决方案**：
+
+```bash
+# 完全清理并重新部署./deploy.sh clean./deploy.sh setup./deploy.sh init
+```
+
+**说明**：
+
+* PostgreSQL 使用 Docker 卷存储数据，首次启动时会执行 `init-databases.sql`
+* 如果数据卷已存在，即使更新了 SQL 文件也不会重新执行
+* `clean` 命令会删除数据卷，确保下次启动时重新初始化
+
+**重要**：`clean` 命令会删除所有数据，请确保已备份重要数据。
+
+## 📚 进阶使用
+
+### 创建第一个比对工作流
+
+1. 访问 N8N (<http://localhost/n8n/>)
+
+2. 使用 `.env` 中的凭据登录

+Navicat（全称 Navicat Premium）是一款功能强大的数据库管理工具，广泛应用于数据库开发、管理和维护。本文介绍如何使用 Navicat 通过 MySQL 协议连接 Lakehouse。
+
+# 准备工作
+
+* 请参考[Navicat官网](https://www.navicat.com/en/download/navicat-premium)，如果已经安装完毕请跳过。
+
+* 使用Mysql协议连接。目前需要重置密码，即使是新建的账号也需要重置密码。这是因为 MySQL 5.x 版本使用的是 `mysql_native_password` 密钥，而 Lakehouse 需要保存 MySQL 的加密算法。目前，只有在修改密码时，Lakehouse 才会保存 MySQL 密钥的加密算法。您可以修改密码时保持和之前一样这样可以避免影响别的任务连接
+
+* 给用户设置计算集群，由于 MySQL 协议中没有传入设置集群的方式，用户可以使用 SQL 命令为用户添加一个默认计算集群。这样在 MySQL 连接时就会使用该集群。
+
+  * ```SQL
+    ALTER USER user_name SET DEFAULT_VCLUSTER = default;-- 查看集群设置是否生效SHOW USERS;
+    ```
+
+* 准备用户名。 使用 MySQL 协议连接时，地址中只能传入一个 URL，无法拼接 Lakehouse 的 instance_name 和 workspace_name。因此，需要将 instance_name 和 workspace_name 拼接到用户名中。
+
+  * 用户名格式要求如下：
+  * ```Plain
+    登录的账号名称@instance_name.workspace_name
+    ```
+  * **instance_name 获取**：在 工作空间页面 中获取 JDBC 连接串。例如，在 `jdbc:clickzetta://``demoinstance.cn-shanghai-alicloud.api.clickzetta.com/quick_start?virtualCluster=default` 中，`jnsxwfyr` 为 instance\_name。
+  * **workspace\_name 获取**：工作空间的名称。
+
+# 连接Lakehouse
+
+* 点击连接->选择MySQL
+
+* 填写配置信息，如下
+
+| 字段       | 说明                                                    |

+| **主机**   | 每个region的连接地址，具体参考[使用MySQL协议连接 ](use-mysql-client.md) |
+| **端口**   | 可选。默认值:3306                                           |
+| **用户名**  | 登录的账号名称@instance\_name.workspace\_name                |
+| **密码**   | 登录账号的密码                                               |

+## 1. 概述
+
+**网络策略（Network Policy**） 旨在控制对某个服务实例（instance）的访问来源，常用做以下场景：
+
+* 限制仅允许特定的 IP 或网段访问Lakehouse 服务实例的Web服务。
+* 限制仅允许特定的 IP 或网段使用JDBC连接Lakehouse服务实例。
+* 阻止（黑名单）可疑或风险 IP 地址段。
+* 在需要时，为了不影响生产或管理员登录，具备实例管理员角色（instance\_admin）的用户可**临时绕过**并修改网络策略设置。
+
+在实际运维中，结合 IP 白名单、黑名单可显著增强数据的安全性与合规性。
+
+***
+
+## 2. 网络策略（Network Policy）简介
+
+* **核心功能**：通过白名单（Allow\_IP\_List）和黑名单（Block\_IP\_List）来控制哪些网络来源可以访问目标服务实例。
+* **典型效果**：
+  1. 管理和过滤 IP 地址或网段。
+  2. 同时支持白名单（Allow\_IP\_List）和黑名单（Block\_IP\_List）方式配置网络策略。
+  3. 当多条策略生效并叠加时，采用“Deny 优先”原则。
+
+***
+
+## 3. 网络策略的工作原理与使用场景
+
+### 3.1 默认逻辑
+
+* **当系统无任何网络策略**时，默认允许所有 IP 访问（相当于“Allow 0.0.0.0/0”）。
+* 一旦创建并激活了至少一条网络策略，系统会根据**所有生效策略**的白名单及黑名单规则进行过滤。
+
+### 3.2 白名单（Allow）与黑名单（Block）的运算
+
+在同一条网络策略中或多条生效策略的结果中：
+
+* 如果有任一生效的白名单策略，则没有在白名单策略中的某个IP/网段将被阻止。
+* 如果没有任何生效的白名单，则除生效的黑名单指定的IP/网段外，其他IP/网段将被放行。
+* 最终出现任意黑名单规则命中时，该 IP 即被拒绝。
+
+### 3.3 多条策略生效与优先级
+
+* 多条策略并行生效时，白名单取并集，黑名单取并集。
+* 多条网络策略之间无优先级关系，系统会对所有生效的网络策略做逻辑运算，并得出当前最终的网络策略结果。
+
+### 3.4 适用范围
+
+网络策略适用于控制从外部网络访问Lakehouse服务的请求，访问方式包括：
+
+* JDBC
+* SDK
+* Web页面
+
+特殊情况说明：
+
+* MySQL兼容协议访问Lakehouse时，只要有“生效”状态的网络策略，无论白名单、黑名单的内容，均会拦截所有MySQL流量。
+
+***
+
+## 4. 核心属性与限制
+
+### 4.1 网络策略属性
+
+| 属性名称                | 是否必填 | 取值范围                                | 默认值      | 说明                               |
+| ------------------- | ---- | ----------------------------------- | -------- | -------------------------------- |
+| **Name**            | 是    | 字母或下划线开头，3-28 个字符，自动转小写，仅限字母/数字/下划线 | 无        | 策略名称在实例内唯一。                      |
+| **Allow\_IP\_List** | 是    | IPv4 单 IP 或 CIDR，逗号分隔，数量上限 \~10 万   | 无        | 允许访问的 IP 或网段。 不允许出现 `0.0.0.0/0`。 |
+| **Block\_IP\_List** | 否    | IPv4 单 IP 或 CIDR，逗号分隔，数量上限 \~10 万   | 无        | 阻止访问的 IP 或网段。 不允许出现 `0.0.0.0/0`。 |
+| **Status**          | 是    | `Activate` 或 `Inactive`             | Activate | 新建默认“生效”，可同时存在多条生效策略。            |
+
+### 4.2 限制与注意事项
+
+1. **最大策略数**：同一实例最多可创建 20条网络策略。
+2. **单策略 IP 数量限制**：白名单、黑名单各自最多可各容纳 10 万个 IP/CIDR。
+3. **策略生效延迟**：网络策略存在缓存生效机制，一般最多 5 分钟内生效。
+4. **删除后不可恢复**：请谨慎操作。尤其多条网络策略同时生效时，逻辑关系较为复杂，删除已生效的策略，可能会导致禁止或允许访问的范围产生较大变化。
+
+***
+
+## 5. 操作指南
+
+以下操作可通过 SQL 命令或前端管理控制台来完成，具体以您所在产品的实际实现为准。
+
+### 5.1 创建网络策略
+
+该操作仅限具备实例管理员（instance\_admin）角色的用户执行。
+
+**Web 操作**：
+
+在“管理”-“安全”-“网络策略”功能中，点击“+新建策略”。
+
+在弹窗中填写“策略名称”，并根据实际需要填写IP白名单或IP黑名单中的内容。
+
+:-: ![](.topwrite/assets/image_1742472677609.png =791)
+
+**SQL 操作**：
+
+```sql
+CREATE [ OR REPLACE ] NETWORK POLICY <name>
+ALLOWED_IP_LIST = ( [ '<ip_address>' ] [ , '<ip_address>' , ... ] )
+[ BLOCKED_IP_LIST = ( [ '<ip_address>' ] [ , '<ip_address>' , ... ] ) ];
+
+
+--示例：
+CREATE NETWORK POLICY policy1
+  ALLOWED_IP_LIST = ('192.168.11.1','192.168.11.2','10.0.0.1/24')
+  BLOCKED_IP_LIST = ('192.168.11.99');
+```
+
+注意：
+
+* 同一个服务实例中，网络策略的名称不可重复。
+* 白名单和黑名单中支持填写 IPV4 IP或CIDR，但不支持0.0.0.0/0。 当白名单为空时，表示全部允许。
+* 同一条网络策略中，白名单或黑名单内的IP/CIDR不允许重复添加，但允许存在交集。不同网络策略中，白名单或黑名单内的IP/CIDR允许重复或存在交集。
+* 创建成功后状态默认为 `Activate`（可立即生效或可被再次激活/使用，视产品而定）。
+* 当前访问Lakehouse所使用的IP也可被写入白名单/黑名单内。如果将当前使用的IP加入黑名单，将导致策略生效后，对当前服务实例的访问立即被阻止。请谨慎操作。
+
+### 5.3 修改网络策略
+
+**Web 操作**：
+
+在“管理”-“安全”-“网络策略”功能中，在需要修改的网络策略右侧的“操作”栏中点击“编辑”按钮，在弹窗中对该网络策略进行修改。
+
+其中，
+
+网络策略的名称不允许修改。仅可以修改网络策略中的白名单/黑名单所包含的IP内容。
+
+:-: ![](.topwrite/assets/image_1742472725009.png =783)
+
+**SQL 操作**：
+
+```
+ALTER NETWORK POLICY [ IF EXISTS ] <name>
+SET 
+  ALLOWED_IP_LIST = ( [ '<ip_address>' ] [ , '<ip_address>' , ... ] )
+[ BLOCKED_IP_LIST = ( [ '<ip_address>' ] [ , '<ip_address>' , ... ] ) ];
+
+--示例：
+ALTER NETWORK POLICY policy1
+SET 
+	ALLOWED_IP_LIST = ('192.168.11.1')
+	BLOCKED_IP_LIST = ('192.168.11.99');
+```
+
+注意：
+
+* 修改网络策略的SQL操作是\*\*“覆盖”**操作，ALTER语句中务必包含ALLOWED\_IP\_LIST和BLOCKED\_IP\_LIST中**所有\*\*需要允许和拒绝的IP范围。
+
+例如：
+
+```
+--创建一条示例的网络策略
+CREATE NETWORK POLICY policy1
+  BLOCKED_IP_LIST = ('192.168.11.99');
+
+--以下语句执行后的policy1，仅包含ALLOWED_IP_LIST = ('192.168.11.100')
+ALTER NETWORK POLICY policy1 SET 
+ALLOWED_IP_LIST = ('192.168.11.100');
+
+--不执行上面的ALTER语句，而执行以下ALTER语句修改网络策略后，policy1中包含：ALLOWED_IP_LIST = ('192.168.11.1'）和BLOCKED_IP_LIST = ('192.168.11.99')
+ALTER NETWORK POLICY policy1
+SET 
+	ALLOWED_IP_LIST = ('192.168.11.1')
+	BLOCKED_IP_LIST = ('192.168.11.99');
+
+```
+
+### 5.4 生效/失效网络策略
+
+**Web 操作**：
+
+在“管理”-“安全”-“网络策略”功能中，在需要修改的网络策略右侧的“操作”栏中点击“停用”/“启用”按钮，即可切换网络策略的状态。
+
+:-: ![](.topwrite/assets/image_1742472766197.png =799)
+
+**SQL 操作**：
+
+```
+ALTER NETWORK POLICY <name> ACTIVATE;
+ALTER NETWORK POLICY <name> INACTIVATE;
+
+--示例：
+CREATE NETWORK POLICY policy1 ACTIVATE;
+CREATE NETWORK POLICY policy1 INACTIVATE;
+```
+
+* 可以在列表或详情处进行“置为生效/置为失效”操作。
+
+* 具体生效/失效后对其他策略的影响，依您的产品是否允许多策略生效而定（有的只允许单一账号策略有效，激活新策略会自动替换上一个；也有的允许多条策略并行）。
+
+### 5.5 删除网络策略
+
+**Web 操作**：
+
+在“管理”-“安全”-“网络策略”功能中，在需要修改的网络策略右侧的“操作”栏中点击“停用”/“启用”按钮，即可切换网络策略的状态。
+
+:-: ![](.topwrite/assets/image_1742472815202.png =793)
+
+**SQL 操作**：
+
+```
+DROP NETWORK POLICY  <name>;
+
+--示例：
+drop network policy policy1;
+```
+
+* 删除后不可恢复。
+
+### 5.6 查看网络策略
+
+**Web 操作**：
+
+在“管理”-“安全”-“网络策略”功能中，可以查看当前服务实例中所有的网络策略。
+
+:-: ![](.topwrite/assets/image_1742472860368.png =783)
+
+**SQL 操作**：
+
+* **显示所有策略**：
+
+```
+SHOW NETWORK POLICY;
+```
+
+返回字段包括：
+
+| **字段**        | **说明**                   |
+| ------------- | ------------------------ |
+| NAME          | 策略名称                     |
+| CREATOR       | 创建者的username             |
+| CREATED\_TIME | 格式为：yyyy-mm-dd hh\:mm:ss |
+| STATUS        | active、inactive          |
+
+* **查看详情**：
+
+```
+DESC NETWORK POLICY <name>;
+```
+
+* 返回策略中 `ALLOWed_IP_LIST` / `BLOCKed_IP_LIST`
+
+| **字段**            | **说明**                   |
+| ----------------- | ------------------------ |
+| NAME              | 策略名称                     |
+| ALLOWED\_IP\_LIST | 创建者的username             |
+| BLOCKED\_IP\_LIST | 格式为：yyyy-mm-dd hh\:mm:ss |
+
+### 5.7 临时绕过网络策略访问
+
+* 在极端情况下（如白名单配错或黑名单阻止了所有网段），可由具备实例管理员角色（instance\_admin)的用户
+
+  创建**临时绕过**策略，使指定用户在 30 分钟内不受网络策略限制。
+
+* 在某些产品或环境中，该功能通过设置用户对象属性 `MINS_TO_BYPASS_NETWORK_POLICY` 来实现，需要联系管理员或官方支持来配置。
+
+***
+
+## 6. 权限与安全控制
+
+| Privilege code        | 操作                 | 默认授予角色 / 权限               |
+| --------------------- | ------------------ | ------------------------- |
+| create network policy | CREATE             | 仅授予实例管理员（instance\_admin） |
+| alter                 | ALTER/RENAME/激活/失效 | 仅授予实例管理员（instance\_admin） |
+| drop                  | DROP               | 仅授予实例管理员（instance\_admin） |
+| read metadata         | SHOW / DESC /      | 仅授予实例管理员（instance\_admin） |
+
+***
+
+## 7. 常见问题（FAQ）
+
+1. **同一个 IP 同时在白名单和黑名单出现，结果如何**？
+   * 黑名单优先，访问被阻断。
+2. **当没有创建任何网络策略时，默认是允许还是拒绝访问**？
+   * 默认允许所有 IP，等效于白名单包含所有IP。
+3. **为何禁止使用** \`\` **在白名单/黑名单中**？
+   * 该表示意味着“所有 IP”。在白名单中没有实际意义（表示开放全部），在黑名单中则完全阻断所有访问，如果没有例外规则，就会导致任何人都无法访问。
+4. **是否能对同一实例同时启用多条网络策略**？
+   * 允许同一服务实例创建多条网络策略且并行生效。系统将所有生效策略中的网络策略中的白名单/黑名单规则取并集后再应用。
+5. **如何避免实例管理员自己被策略锁住**？
+   * 在创建或激活策略前，请确保您自己的 IP（可在web端创建或修改网络策略时看到）已包含在白名单中。若仍意外被阻断，实例管理员（instance\_admin）可通过修改网络策略来恢复自己对服务实例的访问。

+
+## 智能数据处理实战
+
+### 第一步：数据质量诊断
+
+用户只需自然语言提问："*这些数据需要做哪些清洗转化提高分析效果*？"
+
+Claude Desktop通过云器Lakehouse MCP Server自动执行数据质量分析：
+
+**发现的主要问题**：
+
+* 空值问题：23,304 条记录（6.6%）的乘客数量为空
+* 异常值：16,850 条记录（4.8%）的行程距离 ≤ 0
+* 时间异常：1,713 条记录的下车时间早于上车时间
+* 费用计算错误：40,942 条记录（11.6%）费用计算不一致
+
+### 第二步：智能数据清洗
+
+用户请求："*请按顺序都执行*"
+
+Claude Desktop自动生成并执行清洗方案：
+
+#### 异常数据过滤
+
+```sql
+-- 自动生成的清洗逻辑
+CREATE TABLE nyc_green_taxi_2025_cleaned AS 
+SELECT *,
+    -- 修复passenger_count空值
+    CASE 
+        WHEN passenger_count IS NULL THEN 1
+        WHEN passenger_count = 0 THEN 1  
+        WHEN passenger_count > 6 THEN 6
+        ELSE passenger_count
+    END as passenger_count_cleaned,
+    
+    -- 计算行程时长（分钟）
+    TIMESTAMPDIFF(MINUTE, lpep_pickup_datetime, lpep_dropoff_datetime) as trip_duration_minutes
+FROM nyc_green_taxi_2025
+WHERE 
+    lpep_dropoff_datetime > lpep_pickup_datetime
+    AND trip_distance > 0 AND trip_distance < 100
+    AND fare_amount > 0 AND fare_amount < 500
+    AND total_amount > 0 AND total_amount < 1000
+```
+
+**清洗效果**：
+
+* 数据保留率：93.93%（330,257 条有效记录）
+* 空值消除率：100%
+* 异常值清理率：100%
+
+### 第三步：时间维度增强
+
+Claude Desktop智能识别时间分析需求，自动添加时间维度字段：
+
+```sql
+-- 自动增加的时间分析字段
+ALTER TABLE nyc_green_taxi_2025_cleaned ADD COLUMNS (
+    pickup_year INT,
+    pickup_month INT,
+    pickup_hour INT,
+    pickup_dayofweek INT,
+    pickup_is_weekend BOOLEAN,
+    pickup_time_period STRING,  -- 早高峰/晚高峰/平时/深夜
+    pickup_season STRING        -- 春夏秋冬
+);
+```
+
+**时间模式洞察**：
+
+* 春季出行最多（28.82%）
+* 平时时段占比最高（63.83%）
+* 早高峰（7-9 点）和晚高峰（17-19 点）特征明显
+
+### 第四步：业务指标计算
+
+系统自动计算关键业务指标：
+
+```sql
+-- 智能生成的业务指标
+trip_speed_mph,          -- 平均速度（英里/小时）
+fare_per_mile,           -- 每英里费用
+tip_rate,                -- 小费率
+trip_distance_category,  -- 距离分类（短途/中途/长途）
+fare_category,           -- 费用分类（低价/中价/高价）
+passenger_load_factor    -- 载客率分类
+```
+
+**业务洞察发现**：
+
+* 中途行程（1-5 英里）占主导地位（68.4%）。
+* 平均行程速度：12.0 英里/小时。
+* 信用卡支付占 74.79%，现金支付 24.26%。
+
+### 第五步：分类字段标准化
+
+将编码转换为可读标签：
+
+| 原始编码            | 标准化标签         | 占比     |
+| --------------- | ------------- | ------ |
+| vendorid=2      | VeriFone Inc  | 85.34% |
+| payment\_type=1 | Credit Card   | 74.79% |
+| ratecodeid=1    | Standard Rate | 94.28% |
+
+### 第六步：性能优化
+
+创建优化表并建立索引：
+
+* 数据压缩：从 17.2 MB 优化到 9.37 MB
+* 创建 BLOOMFILTER 索引提升查询性能
+* 支持高效的位置和供应商筛选
+
+## 核心MCP工具函数介绍
+
+### 数据查询工具
+
+* **read_query**: 执行 SELECT 查询，支持结果限制
+* **write_query**: 执行 DDL/DML 操作
+* **desc_object**: 查看表结构和元数据信息
+
+### 数据管理工具

+# 云器Lakehouse对象模型概览
+
+云器 Lakehouse 采用分层结构管理资源，以提高数据组织和访问的效率。以下是 Lakehouse 对象模型的详细说明和示例。
+
+![](.topwrite/assets/object-hierarchy.png)
+
+## 账户（Account）
+
+云器的账户是代表与云器公司建立商业关系的组织或个人（通常是企业账户），用于开通云器产品服务、付费、获取服务支持等。账户在注册时将自动生成一个全局唯一的账户名，作为您在云器产品中的唯一标识。
+
+**特点：**
+- 账户负责充值、出账单、费用支付以及订购或变更云器产品。
+- 所有企业或个人在云器产品上开通的服务实例及其资源对象都归属于特定账户。
+
+**示例：**
+假设您是一家名为“XYZ科技”的企业，注册云器账户后，系统为您生成的账户名为“xyztech0128”，您的账户 URL 为“xyztech0128.accounts.clickzetta.com”。
+
+## 用户（User）
+
+账户注册成功后，您可以创建多个用户共同使用同一个账户内的资源。不同用户间可以通过权限控制分配可使用的数据和资源。
+
+**示例：**
+在“XYZ科技”的账户下，您可以创建多个用户，如“alice”（负责数据分析）、“bob”（负责数据开发）等。您可以根据他们的职责分配不同的权限，确保数据安全和高效协作。
+
+## 服务实例（Lakehouse Instance）
+
+Lakehouse 服务实例是云器 Lakehouse 产品服务的载体。在开通 Lakehouse 服务时，您需要根据指定的云服务商和地域，在账户下创建服务实例。一个账户下可以创建一个或多个服务实例（当前阶段默认仅支持创建单个服务实例）。
+
+**特点：**
+- 服务实例采用统一元数据管理数据对象、计算资源、作业任务；
+- 服务实例具备区域属性，其计算、数据和其他服务资源均在此云服务商的区域内；
+- 不同服务实例间默认相互隔离。
+
+**示例：**
+“XYZ科技”需要在阿里云和腾讯云分别部署 Lakehouse 服务，可以在其账户下创建两个服务实例：“ali-lakehouse”和“tencent-lakehouse”。
+
+## 工作空间（Workspace）
+
+工作空间是用于组织 Lakehouse 资源对象（数据对象、计算资源、用户等）并提供配套数据开发能力的逻辑对象。一个服务实例下可以创建多个工作空间。工作空间之间默认隔离，用户需加入工作空间，才可使用该工作空间内的对象。同一实例下不同工作空间内的对象，可通过跨工作空间授权的方式实现共享。
+
+**特点：**
+- 工作空间用于组织和管理数据开发、计算资源等对象。
+- 工作空间之间相互隔离，确保数据安全和高效协作。
+
+**示例：**
+在“ali-lakehouse”服务实例下，您可以创建两个工作空间：“data-dev”（负责数据开发）和“data-ops”（负责数据运维）。
+
+## 计算资源（Virtual Cluster）
+
+计算资源由多实例虚拟计算集群和运行在集群中的计算服务构成，为用户作业提供计算环境，包括 CPU、内存以及临时存储。
+
+## Schema
+
+在工作空间内，Schema 是一组数据库对象的命名空间。数据库对象包括表、视图等。一个工作空间内可以包含多个命名各异的 Schema。
+
+## 表（Table）
+
+表是格式化的二维数据表格。
+
+## 视图（View）
+
+视图是一种虚拟存在的表，并不在数据库中实际存在，在使用时动态生成。
+
+## 物化视图（Materialized View）
+
+物化视图是一种特殊的视图，相对普通视图，物化视图在数据库中实际存在，并占用存储资源。
+
+## Lakehouse SQL任务（JOB）
+
+Lakehouse SQL 任务是指在 Lakehouse 中通过 Web 端数据开发功能或 CLI、JDBC 连接等方式提交的 SQL 查询任务。

+# Lakehouse对象命名规则
+
+在Lakehouse中，为了确保元数据（如数据库、表、视图、用户等）的命名一致性和可读性，避免潜在的问题，我们制定了一套命名规则。本文档将详细介绍这些规则，帮助您更好地理解和使用Lakehouse。
+
+## 标识符类型
+
+Lakehouse支持以下类型的标识符命名：
+
+* **常规标识符**：不需要引号，但必须符合特定的命名规则。
+* **双引号标识符**：需要使用双引号（"）包围起来，可以对关键字进行转译。
+* **反引号标识符**：需要使用反引号（\`）包围起来，可以包含任何字符，但不能包含反引号本身。默认是反引号，可以通过设置切换为双引号（set `cz.sql.double.quoted.identifiers=true`）。
+
+## 命名规则
+
+### 常规标识符的命名规范
+
+1. **开头字符**：标识符必须以字母（包括大写A-Z、小写a-z）或下划线（"\_"）作为起始字符。不允许以数字或其他特殊字符开始。
+2. **字符组成**：标识符中只能包含字母、下划线和十进制数字（0-9）。不允许使用其他特殊字符和关键字，如连字符（-）、空格或其他非字母数字字符。
+3. **大小写敏感性**：虽然在创建时可以指定大小写，但元数据在存储时会被解析为小写字符。在Lakehouse中，所有对象的名称都是不区分大小写的。这意味着，"MyTable"和"mytable"会被视为相同的标识符。
+4. **语言限制**：不支持中文字符
+5. **长度限制**： 长度为1～256个字符，WORKSPACE NAME长度限制3～28个字符
+
+以下是几个合法的标识符示例：
+
+```SQL
+my_table
+table1
+table_2
+```
+
+### 反引号标识符
+
+如果在对象命名时加上反引号，则遵循以下规则：
+
+* 允许用户使用关键字。
+* 列名允许特殊字符、中文等。
+
+对于需要使用关键字命名的标识符名称，可以使用双引号或反引号将其包围，例如：
+
+```SQL
+-- 允许数字
+create schema `123`;
+-- 使用关键字作为对象的命名
+create schema `select`;
+-- 列名使用关键字作为对象的命名
+create table my_table(`中文` string)
+```
+
+请注意，反引号都可以用来包围标识符，但在某些情况下，它们的行为可能不同。通常，建议只在必要时才使用反引号。
+
+### 双引号标识符
+
+在SQL的ANSI/ISO标准中，双引号中的标识符（分隔标识符）允许用户使用关键字。Lakehouse也可以兼容此行为。开启后，双引号为分隔符标识符，通过设置`cz.sql.double.quoted.identifiers=true`当前只支持会话级别开启。需要注意的是，如果开启双引号为分隔符标识符后，Lakehouse将不再把双引号括起来的数据认为是一个字符串类型。
+
+```SQL
+"[ ... ]"
+```
+
+**注意事项**
+
+* 如果使用双引号标识符创建对象，则在查询或任何其他SQL语句中引用该对象时，如果是关键字必须完全按照创建时指定标识符，包含双引号。不包含双引号可能会导致错误。
+
+  ```SQL
+   --需要使用关键字作为对象的命名
+   create schema "select"
+  ```
+
+# 各个对象的命名规范

+# ClickZetta Travel：数据迁移与SQL转译工具
+
+## 简介
+
+ClickZetta Travel 是由云器研发团队精心打造并开源的一款工具，旨在帮助用户轻松实现从其他数据系统向 ClickZetta Lakehouse 的数据迁移。它提供了一系列强大的功能，包括：
+- 将其他 SQL 方言转译为 ClickZetta Lakehouse 兼容的 SQL。
+- 在源数据系统和 ClickZetta Lakehouse 上分别执行 SQL 并对比结果集。
+- 易于使用的 Web UI，提供直观的操作界面。
+- 命令行工具，支持批量 SQL 迁移。
+
+## 安装与启动
+
+### 安装步骤
+
+1. 确保已安装 Docker。
+2. 通过以下命令获取 ClickZetta Travel 的 Docker 镜像：
+
+```shell
+# 获取镜像
+docker pull clickzetta/clickzetta-travel:dev
+```
+
+3. 在本地创建一个名为 `travel` 的文件夹，用于存放评估所需的配置和数据。
+
+```shell
+mkdir travel
+cd travel
+```
+
+### 启动 Web UI
+
+运行以下命令启动 ClickZetta Travel 的 Web UI：
+
+```shell
+docker run --rm --name cztravel -v $(pwd):/mnt/userdata -p 8501:8501 clickzetta/clickzetta-travel:dev
+```
+
+访问 http://localhost:8501/unify 即可使用 Web UI。
+
+## 使用方法
+
+### Web 页面交互式评估
+
+#### 转译 SQL
+
+1. 在浏览器中打开 http://localhost:8501/unify。
+2. 选择您所使用的数据平台。
+3. 在输入框中填入待转译的 SQL。
+4. 使用快捷键（输入框右下角有提示）或使输入框失去焦点，待输入内容生效后，页面将自动以左右对比的方式展示原始和转译后的 SQL。
+
+![transpile screenshot](travel_screenshot_transpile.png)
+
+#### 执行 SQL 并对比结果
+
+1. 进行数据库连接配置。
+   - 展开页面上的 config template，可以看到配置文件模板。
+   - 将编辑好的配置文件通过页面上传；或直接在宿主机数据目录下新建 conf 子目录，并在此处准备好配置文件，刷新页面后即可从 “select config file” 处选择。
+   - 若配置文件正确，页面将展示连接成功的信息。
+2. 选择校验方式，并点击 Validate 按钮运行 SQL 并校验结果集。
+   - Basic verification：基于有限的基础统计信息校验。
+   - Multidimensional verification：基于丰富的统计信息校验。
+   - Line by line verification：逐行校验。
+
+![validate screenshot](travel_screenshot_validate.png)
+
+### 命令行批量评估
+
+收集待评估的 SQL 语句，将其以一个或多个文件的形式存放到数据目录。当一个文件内包含多个 SQL 语句时，语句间需以分号（;）分隔。
+
+```shell
+# 进入 docker 的命令行环境
+docker exec -it cztravel /bin/bash
+# 切换到数据目录
+cd /mnt/userdata
+```
+
+命令行环境中提供的批量评估命令为 `travel`。该工具：
+- 接受一个或多个内容为以分号分隔的 SQL 的文件。
+- 识别并拆分、编号输入文件中的 SQL 语句，将其转译为 ClickZetta Lakehouse SQL，并在 Lakehouse 上尝试执行这些语句。
+- 产出数据目录，包括评估摘要以及运行数据。运行数据包括执行成功的 SQL 语句、无法转译的 SQL 语句以及智能分类过的执行失败的 SQL 语句。
+- 通过 `travel --help` 可以获取最新的帮助信息。
+
+示例：
+```shell
+root@bce68cf855b8:/mnt/userdata#> travel -c conf/cz_conf.json batch-0906.sql
+
+# 屏显持续输出运行日志，直至最终给出运行摘要

+# 分区
+
+分区是一种通过在写入时将相似的行分组在一起来加快查询速度的方法。使用分区可以实现数据裁剪，优化查询。查询表时通过WHERE子句指定所需查询的分区，避免全表扫描，提高处理效率，降低计算资源消耗。
+
+## Lakehouse分区实现
+
+Lakehouse的分区类似于Apache Iceberg的[隐藏分区](https://iceberg.apache.org/docs/latest/partitioning/#icebergs-hidden-partitioning)。为了便于理解，我们参考Apache Iceberg的分区概念来介绍Lakehouse分区。
+Apache Iceberg是一个开源的表格格式，Apache Iceberg支持两种分区方式：标识分区和转换分区。
+
+* 标识分区：将表的一个或多个列作为分区键，根据列的值将数据划分为不同的分区。通过获取列值并选择性地对其进行转换来生成分区值
+* 转换分区：将表的一个或多个列经过某种转换函数后作为分区键，根据转换后的值将数据划分为不同的分区。例如，如果表有一个timestamp列，可以使用`years(timestamp)`函数将数据按照从1970年到现在的多少年，不能直接使用TIMESTAMP类型作为分区列,需要使用生成列转换为整数类型(如
+years, months, days)
+
+分区信息和数据文件的路径存储在元数据中。这样做的好处是可以在不影响数据的情况下修改分区策略，也可以隐藏分区信息，不需要在写SQL时指定分区条件。同时分区数量没有限制，因为数据就是分区。
+
+Lakehouse兼容了一部分Apache Iceberg的转换分区函数。但是Apache Iceberg的year、month、day、hour转换分区和数据库中的常用日期函数名称冲突，因此在Lakehouse中的转换分区为years、months、days、hours。以下是Lakehouse支持的分区转换函数：
+
+|                           |                                   |                                                         |      |
+| ------------------------- | --------------------------------- | ------------------------------------------------------- | ---- |
+| 分区函数名称                    | 描述                                | 源类型                                                     | 结果类型 |
+| bucket(numBuckets, colName) | 值的散列值，对N取模                        | int, long, decimal, date, timestamp\_ltz, string binary | int  |
+| truncate(colName,W)       | 值截断到宽度W                           | int, long, decimal, string                              | 源类型  |
+| years                     | 提取日期或时间戳的年份，以1970年为基准             | date, timestamp, timestamptz                            | int  |
+| months                    | 提取日期或时间戳的月份，以1970-01-01为基准        | date, timestamp, timestamptz                            | int  |
+| days                      | 提取日期或时间戳的天数，以1970-01-01为基准        | date, timestamp, timestamptz                            | int  |
+| hours                     | 提取时间戳的小时数，以1970-01-01 00:00:00为基准 | timestamp, timestamptz                                  | int  |

+## Lakehouse分区语法
+
+### 介绍
+
+Lakehouse是基于Apache Iceberg实现的[隐藏分区](https://iceberg.apache.org/docs/latest/partitioning/#icebergs-hidden-partitioning)，为了兼容大多数习惯使用Hive语法的用户，Lakehouse在语法层面实现了一些语法糖。**特别需要注意的是，Apache Hive要求分区列位于列定义的末尾，但Apache Iceberg没有这种强制要求。因此，如果按照原来的Hive方式加列，可能会将列加到最后一个位置，所以加列时必须指定位置。**比如Apache Iceberg在创建分区时语法为如下
+
+```SQL
+CREATE TABLE prod.db.sample (
+id bigint,
+category string,
+data string
+)
+PARTITIONED BY(category)
+```
+
+Hive的语法必须这样
+
+```SQL
+CREATE TABLE prod.db.sample (
+id bigint,
+data string)
+PARTITIONED BY(category string)
+```
+
+Lakehouse做了兼容，既支持Iceberg语法也支持Hive语法。分区字段和类型写在PARTITIONED BY语句中。
+
+### 支持的语法
+
+lakehouse兼容了Hive的分区语法，支持以下几种分区操作：
+
+* Insert into…partition：向表的一个或多个分区中插入数据，如果分区不存在，则自动创建分区，因为分区就是数据。partition子句可以省略，数据会自动根据列的顺序进行映射，但要求分区列和表中对应列的位置必须一致。而在Hive中您必须指定partition子句
+
+* Insert overwrite…partition：覆盖表的一个或多个分区中的数据，如果分区不存在，则自动创建分区。
+  * partition子句可以省略，数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。
+
+  * overwrite行为遵循Hive的原则，如果指定分区且为静态值，则是静态覆盖，即只覆盖指定的分区；如果指定分区且为动态值，或者不指定分区，则是动态覆盖，即覆盖所有匹配的分区。如果表中分区是转换分区，partition子句不支持指定转换函数，可以直接使用insert overwrite table插入数据。
+
+  * ```SQL
+    INSERT OVERWRITE [TABLE] table_name 
+    --partition关键字可选
+    [ PARTITION partition_spec] 
+    [ column_list ]
+    VALUES(value [,...])| select_statement
+    --如果指定PARTITION关键字时partition_spec必选
+    partition_spec ::=
+        partition_col_name = partition_col_val [ , ... ] | partition_col_name
+    ```
+
+* Truncate partition：清空表的一个或多个分区中的数据。但在Hive中会保留分区值，Lakehouse中则不会保留，因为Lakehouse的partition是数据
+
+  * ```SQL
+    TRUNCATE [TABLE] table_name [PARTITION partition_spec];
+    --partition_spec解释
+    partition_spec::=
+      partition_column = partition_col_value, partition_column = partition_col_value, ...)
+    ```
+
+* Drop partition：删除表的一个或多个分区。
+
+  * ```SQL
+    ALTER TABLE table_name DROP [IF EXISTS] PARTITION 
+    partition_spec[, PARTITION partition_spec, ...]
+    ```
+
+* Rename partition:目前您可以直接update更新数据即可
+
+  * ```SQL
+     update sales set order_date='2023-02-02' where order_date= '2023-02-01';
+    ```
+
+* Show partition:建议使用SQL，select distinct进行统计，如`select distinct pt from table_pt;`
+
+### 支持的分区数据类型
+
+
+| 数据类型                     | 是否支持 |
+| ------------------------ | ---- |

+| SMALLINT                 | 支持   |
+| INT                      | 支持   |
+| BIGINT                   | 支持   |
+| STRING                   | 支持   |
+| CHAR(n)                  | 支持   |
+| VARCHAR(n)               | 支持   |
+| BOOLEAN                  | 支持   |
+| BINARY                   | 不支持  |
+| FLOAT                    | 不支持  |
+| DOUBLE                   | 不支持  |
+| DECIMAL(precision,scale) | 不支持  |
+| TIMESTAMP\_LTZ           | 不支持  |
+| INTERVAL（时间间隔类型）         | 不支持  |
+| ARRAY                    | 不支持  |
+| MAP                      | 不支持  |
+| STRUCT                   | 不支持  |
+
+### 写入分区
+
+* Insert into…partition：向表的一个或多个分区中插入数据，如果分区不存在，则自动创建分区，因为分区就是数据。partition子句可以省略，数据会自动根据列的顺序进行映射，但要求分区列和表中对应列的位置必须一致。在Hive中您必须指定partition子句
+
+* Insert overwrite…partition：覆盖表的一个或多个分区中的数据，如果分区不存在，则自动创建分区。partition子句可以省略，数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。overwrite行为遵循Hive的原则，如果指定分区且为静态值，则是静态覆盖，即只覆盖指定的分区；如果指定分区且为动态值，或者不指定分区，则是动态覆盖，即覆盖所有匹配的分区。如果表中分区是转换分区，partition子句不支持指定转换函数，可以直接使用insert overwrite table插入数据。
+
+  * ```SQL
+    INSERT OVERWRITE [TABLE] table_name 
+    --partition关键字可选
+    [ PARTITION partition_spec] 
+    [ column_list ]
+    VALUES(value [,...])| select_statement
+    --如果指定PARTITION关键字时partition_spec必选
+    partition_spec ::=
+        partition_col_name = partition_col_val [ , ... ] | partition_col_name
+    ```
+
+**注意**：
+执行写入分区时单个任务目前限制2048个分区，超出此限制将会报错：`The count of dynamic partitions exceeds the maximum number 2048`。插入之前建议您先统计分区的数量如：`select count(distinct pt) from table`。如果您确实有这么多分区可以分批次导入，lakehouse的分区总数没有限制，会在单个任务限制。如果您的数据量较小，建议可以不用设置cluster key和partition key。建议单分区和cluster key的数据量在百MB到GB级别。例如，Parquet格式文件压缩后128MB。

+# 分区
+
+分区是一种通过在写入时将相似的行分组在一起来加快查询速度的方法。使用分区可以达到数据裁剪，优化查询。查询表时通过WHERE子句查询指定所需查询的分区，避免全表扫描，提高处理效率，降低计算资源
+
+## Lakehouse分区实现
+
+Lakehouse的分区类似于Apache Iceberg的[隐藏分区](https://iceberg.apache.org/docs/latest/partitioning/#icebergs-hidden-partitioning)。为了便于理解，我们参考Apache Iceberg的分区概念来介绍Lakehouse分区。
+Apache Iceberg是一个开源的表格格式，Apache Iceberg支持两种分区方法：标识分区和转换分区。
+
+* 标识分区：将表的一个或多个列作为分区键，根据列的值将数据划分为不同的分区。通过获取列值并选择性地对其进行转换来生成分区值
+* 转换分区：将表的一个或多个列经过某种转换函数后作为分区键，根据转换后的值将数据划分为不同的分区。例如，如果表有一个timestamp列，可以使用`years(timestamp)`函数将数据按照从1970年到现在的多少年。
+
+分区信息和数据文件的路径存储在元数据中。这样做的好处是可以在不影响数据的情况下修改分区策略，也可以隐藏分区信息，不需要在写SQL时指定分区条件。同时分区数量没有限制，因为数据就是分区。
+
+lakehouse兼容了一部分的Apache Iceberg的转化换分区函数。但是Apache Iceberg的year、month、day、hour转化分区和数据库中的常用日期函数名称冲突，因此在Lakehouse中的转化分区为years、months、days、hours。以下是lakehouse支持的分区转化函数：
+
+|                           |                                   |                                                         |      |
+| ------------------------- | --------------------------------- | ------------------------------------------------------- | ---- |
+| 分区函数名称                    | 描述                                | 源类型                                                     | 结果类型 |

+| months                    | 提取日期或时间戳的月份，以1970-01-01为基准        | date, timestamp, timestamptz                            | int  |
+| days                      | 提取日期或时间戳的天数，以1970-01-01为基准        | date, timestamp, timestamptz                            | int  |

+## Lakehouse分区语法
+
+### 介绍
+
+Lakehouse的分区为了兼容大多数习惯使用hive语法的用户，Lakehouse在语法层面实现了一些语法糖。**特别注意的是Apache Hive要求分区列是最后一个位置，但是在Apache Iceberg则没有这种强制要求，因此加列的时候特别注意按照原来hive方式加列可能会将列加到最后一个位置，所以加列的时候必须指定位置**。比如Apache Iceberg在创建分区时语法为如下
+
+```SQL
+CREATE TABLE prod.db.sample (
+id bigint,
+category string，
+data string,
+)
+PARTITIONED BY(category)
+```
+
+hive的语法必须这样
+
+```SQL
+CREATE TABLE prod.db.sample (
+id bigint,
+data string)
+PARTITIONED BY(category string)
+```
+
+lakehouse做了兼容即支持iceberg语法也支持hive语法，分区字段和类型写在PARTITIONED BY语句中。
+
+### 支持的语法
+
+lakehouse兼容了Hive的分区语法，支持以下几种分区操作：
+
+* Insert into…partition：向表的一个或多个分区中插入数据，如果分区不存在，则自动创建分区，因为分区就是数据。partition子句可以省略， 数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。在hive中您必须指定parition子句
+
+* Insert overwrite…partition：覆盖表的一个或多个分区中的数据，如果分区不存在，则自动创建分区。partition子句可以省略，数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。overwrite行为遵循Hive的原则，如果指定分区且为静态值，则是静态覆盖，即只覆盖指定的分区；如果指定分区且为动态值，或者不指定分区，则是动态覆盖，即覆盖所有匹配的分区。如果表中分区是转换分区，partition子句不支持指定转换函数，可以直接使用insert overwrite table插入数据。
+
+  * ```SQL
+    INSERT OVERWRITE [TABLE] table_name 
+    --partition关键字可选
+    [ PARTITION partition_spec] 
+    [ column_list ]
+    VALUES(value [,...])| select_statement
+    --如果指定PARTITION关键字时partition_spec必选
+    partition_spec ::=
+        partition_col_name = partition_col_val [ , ... ] | partition_col_name
+    ```
+
+* Truncate partition：清空表的一个或多个分区中的数据。但在hive中会保留分区值，Lakehouse中则不会保留，因为Lakehouse的parition是数据
+
+  * ```SQL
+    TRUNCATE [TABLE] table_name [PARTITION partition_spec];
+    --partition_spec解释
+    partition_spec::=
+      partition_column = partition_col_value, partition_column = partition_col_value, ...)
+    ```
+
+* Drop partition：删除表的一个或多个分区。
+
+  * ```SQL
+    ALTER TABLE table_name DROP [IF EXISTS] PARTITION 
+    partition_spec[, PARTITION partition_spec, ...]
+    ```
+
+* Rename partition:目前您可以直接update更新数据即可
+
+  * ```SQL
+     update sales set order_date='2023-02-02' where order_date= '2023-02-01';
+    ```
+
+* Show partition:建议使用SQL，select distinct进行统计，如`select distinct pt from table_pt;`
+
+### 支持的分区数据类型

+| STRUCT                   | 不支持  |
+
+### 写入分区
+
+* Insert into…partition：向表的一个或多个分区中插入数据，如果分区不存在，则自动创建分区，因为分区就是数据。partition子句可以省略， 数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。在hive中您必须指定parition子句
+
+* Insert overwrite…partition：覆盖表的一个或多个分区中的数据，如果分区不存在，则自动创建分区。partition子句可以省略，数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。overwrite行为遵循Hive的原则，如果指定分区且为静态值，则是静态覆盖，即只覆盖指定的分区；如果指定分区且为动态值，或者不指定分区，则是动态覆盖，即覆盖所有匹配的分区。如果表中分区是转换分区，partition子句不支持指定转换函数，可以直接使用insert overwrite table插入数据。
+
+  * ```SQL
+    INSERT OVERWRITE [TABLE] table_name 
+    --partition关键字可选
+    [ PARTITION partition_spec] 
+    [ column_list ]
+    VALUES(value [,...])| select_statement
+    --如果指定PARTITION关键字时partition_spec必选
+    partition_spec ::=
+        partition_col_name = partition_col_val [ , ... ] | partition_col_name
+    ```
+
+**注意**：
+执行写入分区时单个任务目前限制2048个分区，超出此限制将会报错：`The count of dynamic partitions exceeds the maximum number 2048`。插入之前建议您先统计分区的数量如：`select count(distinct pt) from table`。如果您确实有这么多分区可以分批次导入，lakehouse的分区总数没有限制，会在单个任务限制。如果您的数据量较小建议可以不用设置cluster key和partiiton key。建议单分区和cluster key在百MB到GB级别。例如parquet格式文件压缩后128MB

+# 最佳实践：使用 Pipe 高效接入 kafka 数据
+# 快速验证 kafka 参数
+
+在云器 Lakehouse 中，使用 Kafka pipe 可以非常容易构建分钟级近实时数据集成链路。在开始之前，需要确认三件事：
+
+1. 网络连通性
+2. Kafka bootstrap 地址、端口和 topic
+3. （可选）认证方式及相关参数
+
+上述目的可以通过直接运行形如 `select * from read_kafka()` 查询的方式来快速验证。
+
+这里是一个无认证的 kafka 接入样例：
+
+```SQL
+SELECT *
+FROM read_kafka(
+  'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
+  'topic-name',   -- topic
+  '',             -- reserved
+  'test',         -- kafka group id, for keeping read position
+  '', '', '', '', -- reserved
+  'raw',          -- key format, can only be raw
+  'raw',          -- value format, can only be raw
+  0,
+  MAP(
+    'kafka.security.protocol','PLAINTEXT',
+    'kafka.auto.offset.reset','latest'
+  )
+)
+LIMIT 10;
+```
+
+> read\_kafka 函数参数众多，但是实际需要填写的只有 bootstrap 地址、topic 和 group id。探查阶段我们使用 test 作为 group id
+
+这是一个读取 SASL\_PLAINTEXT 认证方式的样例（pipe 仅支持 PLAINTEXT 和 SASL\_PLAINTEXT）：
+
+```SQL
+SELECT *
+FROM read_kafka(
+  'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
+  'topic-name',   -- topic
+  '',             -- reserved
+  'test',         -- kafka group id, for keeping read position
+  '', '', '', '', -- reserved
+  'raw',          -- key format, can only be raw
+  'raw',          -- value format, can only be raw
+  0,
+  MAP(
+    'kafka.security.protocol','SASL_PLAINTEXT',
+    'kafka.sasl.mechanism','PLAIN',
+    'kafka.sasl.username','<username>',
+    'kafka.sasl.password','<password>',
+    'kafka.auto.offset.reset','latest'
+  )
+)
+LIMIT 10;
+```
+
+如果参数配置无误，执行上述 SQL 将获得 10 行样例数据
+
+![](/.topwrite/assets/image_1760681545512.png)
+
+# 小批量读取数据确认 schema 并创建目标表
+
+kafka 数据中的 key 和 value 都是 binary 类型。通常我们更关心的是 value 的内容。如果其中本来存放就是字符串，可以在 select 的时候 cast 成 string 来快速探查其中内容。
+
+```sql
+SELECT key::string, value::string
+FROM read_kafka(
+  'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
+  'topic-name',   -- topic
+  '',             -- reserved
+  'test',         -- kafka group id, for keeping read position
+  '', '', '', '', -- reserved
+  'raw',          -- key format, can only be raw
+  'raw',          -- value format, can only be raw
+  0,
+  MAP(
+    'kafka.security.protocol','PLAINTEXT',
+    'kafka.auto.offset.reset','latest'
+  )
+)
+LIMIT 10;
+```
+
+![](/.topwrite/assets/image_1760681595348.png)
+
+点击「复制」获取样例数据并探查，可见 value 大体是个 JSON，但是 JSON 中有些 string field 还是个完整的 JSON，看起来还不止一层，结构略复杂：
+
+```JSON

+```
+
+调整 select 语句，使用 parse\_json 将 value 字段和其中的 event 展开：
+
+```SQL
+SELECT
+    parse_json(j['event']::string) as event,
+    j['op_type']::string as op_type,
+    j['datasource_id']::string as datasource_id,
+    j['database_name']::string as database_name,
+    j['schema_name']::string as schema_name,
+    j['table_name']::string as table_name,
+    timestamp_millis(j['event_ts']::bigint) as event_ts,
+    j['event_seq']::string as event_seq,
+    timestamp_millis(j['server_ts']::bigint) as server_ts,
+    j['server_seq']::bigint as server_seq
+FROM (
+    SELECT parse_json(value::string) as j
+    FROM read_kafka(
+    'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
+    'topic_name',   -- topic
+    '',             -- reserved
+    'test',         -- kafka group id, for keeping read position
+    '', '', '', '', -- reserved
+    'raw',          -- key format, can only be raw
+    'raw',          -- value format, can only be raw
+    0,
+    MAP(
+        'kafka.security.protocol','PLAINTEXT',
+        'kafka.auto.offset.reset','latest'
+    )
+    )
+    LIMIT 10
+);
+
+```
+
+运行发现 event 中的 statements 仍然是 JSON。
+
+![](/.topwrite/assets/image_1760681703861.png)
+
+继续调整 select 语句，直到将所有内容为 JSON 的字符串 parse 完毕再落表，避免后续查询重复计算 parse\_json。
+
+```SQL
+SELECT
+    parse_json(j['event']::string) as event,
+    parse_json(parse_json(j['event']::string)['statements']::string) as statements,
+    j['op_type']::string as op_type,
+    j['datasource_id']::string as datasource_id,
+    j['database_name']::string as database_name,
+    j['schema_name']::string as schema_name,
+    j['table_name']::string as table_name,
+    timestamp_millis(j['event_ts']::bigint) as event_ts,
+    j['event_seq']::string as event_seq,
+    timestamp_millis(j['server_ts']::bigint) as server_ts,
+    j['server_seq']::bigint as server_seq
+FROM (
+    SELECT parse_json(value::string) as j
+    FROM read_kafka(
+    'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
+    'topic_name',   -- topic
+    '',             -- reserved
+    'test',         -- kafka group id, for keeping read position
+    '', '', '', '', -- reserved
+    'raw',          -- key format, can only be raw
+    'raw',          -- value format, can only be raw
+    0,
+    MAP(
+        'kafka.security.protocol','PLAINTEXT',
+        'kafka.auto.offset.reset','latest'
+    )
+    )
+    LIMIT 10
+);
+```
+
+根据 select 的探查结果，确定目标表结构，并建表：
+
+```SQL
+CREATE TABLE ods_commit_log (
+    event json,
+    statements json,
+    op_type string,
+    datasource_id string,
+    database_name string,
+    schema_name string,
+    table_name string,
+    event_ts timestamp,
+    event_seq string,
+    server_ts timestamp,
+    server_seq bigint,
+    __kafka_timestamp__ timestamp,
+    pt_date string generated always as (date_format(`server_ts`, 'yyyyMMdd')) stored
+) PARTITIONED BY (pt_date)
+PROPERTIES(
+    'data_lifecycle'='14'
+); 
+```
+
+> 通常 kafka 流入的数据以 append only 的日志表居多，因此基于业务时间戳 server\_ts 增加了自动生成列 pt\_date 作为分区列，并配合 table properties 中的 data\_lifecycle 来对表数据量进行控制
+
+> 表 DDL 中增加了 \_\_kafka\_timestamp\_\_ 字段，记录数据流过 kafka 的时间，这列在业务上鲜有价值，但是可以在数据延迟发生时用于原因诊断，我们建议保留
+
+至此，我们已经完成了 kafka 数据和目标表结构的对齐。
+
+# 正式创建 Pipe
+
+接下来，从已有的探查 select 语句作为基础，构建 Pipe DDL。Pipe 对实际上是对 `COPY INTO <table> FROM (SELECT ... FROM READ_KAFKA(...))` 的封装，同时增加指定计算资源、调度频率等工程参数。
+
+考虑到 Kafka 数据通常为流式进入，如果我们需要目标表的新鲜度为 1 分钟，即 pipe 每 60 秒调度一个 `COPY INTO` 作业，那么建议给 pipe 划分一个专用的 GP 集群。
+
+```sql
+CREATE VCLUSTER pipe_ods_commit_log 
+    VCLUSTER_TYPE = GENERAL 
+    VCLUSTER_SIZE = 1
+;
+```
+
+>先不用纠结这个 GP vcluster 的大小，我们可以在后续的调整阶段根据作业实际执行情况再作调整。
+
+>单独划分集群的原因之一是过高的数据新鲜度（比如小于 5 分钟）会使集群几乎没有空闲的可能，成为事实上的常驻资源消耗。因此通常不应该把 pipe 跑在很大的集群上导致资源浪费。但是反过来看，如果 kafka 流入的数据量较小，也没有必要给每个 pipe 都划分单独的集群。此时可以使一系列 pipe 共享一个常驻集群以节省资源。
+
+Pipe DDL 如下:
+
+1. 去掉 `select ... from read_kafka(...)` 字句里的 `limit 10`
+2. group id 从 test 更换为线上准备正式使用的名字，如 sub2cz
+3. （可选）使用 RESET\_KAFKA\_GROUP\_OFFSETS 参数指定读取 kafka 的时间点（否则会按照 kafka.auto.offset.reset 的设置从 latest 读起），需要使用毫秒单位的 epoch。
+
+```sql
+CREATE PIPE pipe_ods_commit_log 
+    VIRTUAL_CLUSTER = 'pipe_ods_commit_log' 
+    BATCH_INTERVAL_IN_SECONDS = '60'
+    RESET_KAFKA_GROUP_OFFSETS = '1740931200000' -- epoch in millis of 2025-03-03 00:00:00
+AS COPY INTO ods_commit_log FROM (
+SELECT
+    parse_json(j['event']::string) as event,
+    parse_json(parse_json(j['event']::string)['statements']::string) as statements,
+    j['op_type']::string as op_type,
+    j['datasource_id']::string as datasource_id,
+    j['database_name']::string as database_name,
+    j['schema_name']::string as schema_name,
+    j['table_name']::string as table_name,
+    timestamp_millis(j['event_ts']::bigint) as event_ts,
+    j['event_seq']::string as event_seq,
+    timestamp_millis(j['server_ts']::bigint) as server_ts,
+    j['server_seq']::bigint as server_seq,
+    `timestamp` as __kafka_timestamp__
+FROM (
+    SELECT `timestamp`, parse_json(value::string) as j
+    FROM read_kafka(
+    'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
+    'topic_name',   -- topic
+    '',             -- reserved
+    'sub2cz',       -- kafka group id, for keeping read position
+    '', '', '', '', -- reserved
+    'raw',          -- key format, can only be raw
+    'raw',          -- value format, can only be raw
+    0,
+    MAP(
+        'kafka.security.protocol','PLAINTEXT',
+        'cz.kafka.fetch.retry.enable','true', 
+        'cz.kafka.fetch.retry.times','20',
+        'cz.kafka.fetch.retry.intervalMs','2000'
+    )
+)));
+```
+
+>这里我们在 read\_kafka 的参数中补充了 cz.kafka.fetch.retry.enable、cz.kafka.fetch.retry.times、cz.kafka.fetch.retry.intervalMs 三个参数，指定函数在遇到读 kafka 失败时的重试策略。这样有助于减少生产作业的告警和人工介入次数。
+
+Pipe 创建后，会自动开始运行。在 Studio 依次点击「计算」-「集群」-「PIPE\_ODS\_COMMIT\_LOG」-「作业」，我们可以通过这个页面快速检查由 pipe 提交作业的运行情况。
+
+当多个 pipe 复用一个 VCluster 时，也可以用 query\_tag 在 studio 的「计算」-「作业历史」页面或 InformationSchema 的 job\_history 表快速查询指定 pipe 的作业运行情况。由 pipe 提交的作业，其 query\_tag 为 pipe.\<workspace\_name>.\<schema\_name>.\<pipe\_name> 的形式：
+
+```sql
+select query_tag, job_id, status, start_time, end_time, execution_time, input_bytes, output_bytes, rows_produced
+from information_schema.job_history
+where pt_date>='yyyy-MM-dd' -- eg. 2025-03-03
+and query_tag = 'pipe.<workspace_name>.<schema_name>.<pipe_name>' -- eg. 'pipe.quick_start.public.pipe_ods_commit_log'
+order by start_time desc;
+```
+
+# 大数据量及资源调优
+
+优化 Kafka pipe 在生产环境稳定运行，就是在数据新鲜度要求的周期内（BATCH\_INTERVAL\_IN\_SECONDS ），用最小的资源配置（VCluster），恰好完成流入数据的计算和落盘（生产中应保留一定算力冗余，以确保在数据量波动、集群升级作业 failover 等情况发生时，pipe 能够较快追平数据，通常建议保留一倍的冗余度）。用本文的例子通俗的讲，就是至少要能够在 30 秒左右，处理完这 1 分钟由 kafka 流入的数据。
+
+Pipe 的默认设置在大多数情况下工作良好。但如果接入的 kafka 数据量特别大，则应根据实际情况调整参数，如下图红色文字标注部分：
+
+![](/.topwrite/assets/image_1760681949544.png)
+
+
+
+确认当前的 pipe 是否积压，可以通过多次执行`desc pipe extended` 查看 pipe\_latency 行的 timeLag（kafka 点位和当前时间的差距，单位毫秒）是否在持续增加。当数据新鲜度为 60 秒，且算力冗余为一倍时，timeLag 应该在0\~90 秒之间波动（如果完全不做冗余，波动应该在 0\~120 秒之间），当 timeLag 会超过上限且在几个周期之后持续上涨，则 pipe 会产生积压。
+
+## 确认 kafka 的消息峰值（增大 `BATCH_SIZE_PER_KAFKA_PARTITION` 参数）
+
+为了防止 pipe 在启动时读取过多数据导致作业超大作业出现，pipe 会限制每次从 partition 中读取的数据条数，通过 `BATCH_SIZE_PER_KAFKA_PARTITION` 控制，默认 50000。当 kafka 每周期每 partition 的消息峰值超过此值时，应该在 CREATE PIPE 时人工指定该参数。通常建议设置该值为峰值的 2 倍。当 pipe 已经在运行中，也可以通过`alter pipe <pipe_name> set BATCH_SIZE_PER_KAFKA_PARTITION=<event_number>;` 来动态调整该值。
+
+如图所示，虽然 pipe 的分钟作业只要不到 30 秒即可执行完成，但此时 desc pipe extended 指示 timeTag 可能在持续增大。
+
+![](/.topwrite/assets/image_1760681973997.png)
+
+点击作业进入作业详情页，可以看到这是一个 10 个 partition 的 kafka topic。即使设置 BATCH\_SIZE\_PER\_KAFKA\_PARTITION 为 100000，然没有完整读取一个周期所有数据，需要继续增大。
+
+![](/.topwrite/assets/image_1760681981294.png)
+
+最终，通过不断增大该值并持续观察 timeLag（生产使用时通常应该预先知晓 kafka per partition 的峰值，直接设置就好），确定该值为 500000 时，pipe 的消费速度较快可以追平 kafka。
+
+>与直接 `select ... read_kafka(...)` 不同，通过 pipe 生成的 `copy into`作业，可以看到由 pipe 管理的，记录在 kafka group id 中的点位信息，很容易识别读取的 kafka topic 有多少个 partition，以及各个 partition 的实际点位值。
+
+## 调整 VCluster Size
+
+默认情况下，Pipe 启动的 `copy into` 作业，task 数量和 kafka topic partition 数量一致，即每个 task 读取一个 partition。当 VCluster Size 较小时，作业的 task 可能需要多轮才能完全运行结束，从而显著拉长作业运行时间。
+
+因此，当需要作业尽快结束时，应保证 VCluster 的允许的 task 并发度 >= partition 数，使所有 task 一轮运行完。
+
+下图一个使用 128CRU VCluster（1024core）的 pipe 作业，消费 1200 个 partition 的 kafka topic， 需要运行两轮，第一轮 1024 个 task，剩余的 176 个 task 第二轮，显著拉长了运行时间。此时将 VCluster 设置为 150CRU 为宜（1200core）。
+
+![](/.topwrite/assets/image_1760681994525.png)
+
+## 切分 kafka 数据以利用更多计算资源（设置 COPY\_JOB\_HINT）
+
+当 kafka 数据量很大但 partition 数较少，或 pipe 落表前的计算逻辑较为复杂使得单个 task 不足以在周期要求内完成单个 partition 数据量计算时，可以考虑通过设置 COPY\_JOB\_HINT 来对 task 进行进一步拆分，并配合更多计算资源来实现加速的效果。
+
+COPY\_JOB\_HINT 是一个 JSON 形式表达的复合参数，人工切分 kafka 数据需要联合使用一下两个 key：
+
+1. "cz.sql.split.kafka.strategy":"size"默认为 "simple"，即每个 partition 划分一个 task。须更改为 "size"，意为按照条数来切分 task。
+2. "cz.mapper.kafka.message.size":"200000"指示 pipe 多少 event 划分一个 task，默认值 1000000，当 "cz.sql.split.kafka.strategy" 为 "size" 时生效。
+
+可以通过 `alter pipe pipe_ods_commit_log set COPY_JOB_HINT = '{"cz.sql.split.kafka.strategy":"size","cz.mapper.kafka.message.size":"200000"}';` 随时调整 pipe 的切分 task 策略。
+
+>COPY\_JOB\_HINT 是 JSON 形式的复合参数，通过 alter pipe 设置时是覆盖行为，需要小心设置某些 key 时意外丢失了之前设置的其他 key。此时可以通过 desc pipe extended 在 properties 行的 copy\_job\_hint 中获取完整设置，并基于此进行修改。
+
+在对参数调整完毕之后，我们建议将同步改动对应的 Pipe DDL，防止后续流程重建/迁移导致参数遗漏。
+
+```SQL
+CREATE VCLUSTER pipe_ods_commit_log 
+    VCLUSTER_TYPE = GENERAL 
+    VCLUSTER_SIZE = 150
+;
+
+CREATE PIPE pipe_ods_commit_log
+    VIRTUAL_CLUSTER = 'PIPE_ODS_COMMIT_LOG' 
+    BATCH_INTERVAL_IN_SECONDS = '60'
+    BATCH_SIZE_PER_KAFKA_PARTITION = 2000000
+    RESET_KAFKA_GROUP_OFFSETS = '1740931200000' -- epoch in millis of 2025-03-03 00:00:00
+    COPY_JOB_HINT = '{"cz.sql.split.kafka.strategy":"size","cz.mapper.kafka.message.size":"200000"}' -- to accelerate load
+AS COPY INTO ods_commit_log FROM 
+...
+```
+
+# 更改 Pipe SQL 逻辑
+
+Pipe 允许在 `copy into` 和 `read_kafka` 之间做比较复杂的计算。当计算逻辑发生变化，或目标表 schema 发生变化时（典型场景是增加列），需要对已有的 pipe 定义进行修改。
+
+简言之，pipe ddl 的修改，是保持 read\_kafka 参数不变的情况下，删除并重建 pipe。
+
+例如我们需要修改 pipe\_ods\_commit\_log，在目标表 event 字段中去掉 statments 的内容（因为和 statments 字段冗余了一份存储），则可以按照如下步骤进行操作：
+
+1. 删除当前运行的 pipe
+
+```SQL
+drop pipe pipe_ods_commit_log;
+```
+
+>对已有 pipe  drop pipe 和 alter pipe，会被 pipe 当前正在运行的作业阻塞，直到作业结束后才会返回，可能会需要些时间。
+
+2. 重建 pipe（注意去掉 RESET\_KAFKA\_GROUP\_OFFSETS 参数）
+
+```sql
+CREATE PIPE pipe_ods_commit_log 
+    VIRTUAL_CLUSTER = 'pipe_ods_commit_log' 
+    BATCH_INTERVAL_IN_SECONDS = '60'
+    BATCH_SIZE_PER_KAFKA_PARTITION = 2000000
+    -- RESET_KAFKA_GROUP_OFFSETS = '1740931200000' -- epoch in millis of 2025-03-03 00:00:00
+    COPY_JOB_HINT = '{"cz.sql.split.kafka.strategy":"size","cz.mapper.kafka.message.size":"200000"}' -- to accelerate load
+AS COPY INTO ods_commit_log FROM (
+SELECT
+    remove_json(parse_json(j['event']::string), '$.statements') as event,
+    parse_json(parse_json(j['event']::string)['statements']::string) as statements,
+    j['op_type']::string as op_type,
+    j['datasource_id']::string as datasource_id,
+    j['database_name']::string as database_name,
+    j['schema_name']::string as schema_name,
+    j['table_name']::string as table_name,
+    timestamp_millis(j['event_ts']::bigint) as event_ts,
+    j['event_seq']::string as event_seq,
+    timestamp_millis(j['server_ts']::bigint) as server_ts,
+    j['server_seq']::bigint as server_seq,
+    `timestamp` as __kafka_timestamp__
+FROM (
+    SELECT `timestamp`, parse_json(value::string) as j
+    FROM read_kafka(
+    'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
+    'topic_name',   -- topic
+    '',             -- reserved
+    'sub2cz',       -- kafka group id, for keeping read position
+    '', '', '', '', -- reserved
+    'raw',          -- key format, can only be raw
+    'raw',          -- value format, can only be raw
+    0,
+    MAP(
+        'kafka.security.protocol','PLAINTEXT',
+        'cz.kafka.fetch.retry.enable','true', 
+        'cz.kafka.fetch.retry.times','20',
+        'cz.kafka.fetch.retry.intervalMs','2000'
+    )
+)));
+```
+
+>Pipe 使用 kafka group 来记录读取的点位，因此只要使用相同的 kafka 集群、topic 及 group id，即使重建 pipe，点位也不会丢失，可以实现「断点续传」的效果。
+
+但是 RESET\_KAFKA\_GROUP\_OFFSETS 会强制改写 group id 中记录的点位，需要谨慎使用。

+# 使用 Table Stream 和 Pipe 将 Kafka 数据导入 Lakehouse
+
+## 一、背景介绍
+
+在大数据处理领域，将 Kafka 中的流数据高效地导入 Lakehouse（数据湖仓）是一个常见的需求。云器科技提供了强大的 Table Stream 和 Pipe 功能，使得这一过程变得更加简便和高效。本文将详细介绍如何使用 Table Stream 和 Pipe 将 Kafka 数据导入 Lakehouse，包括创建 Kafka 外部表和 Kafka Table Stream 的完整过程。
+
+## 二、操作步骤
+
+### 创建 Kafka 外部表
+
+在使用 Table Stream 和 Pipe 之前，我们需要先创建一个与[ Kafka 集成的外部表](create-kafka-external.md)，用于访问 Kafka 中的数据。
+
+```sql
+CREATE STORAGE CONNECTION pipe_kafka
+ TYPE kafka 
+BOOTSTRAP_SERVERS = ['47.00.08.62:9092'] 
+SECURITY_PROTOCOL = 'PLAINTEXT';
+
+CREATE EXTERNAL TABLE external_table_kafka (   
+ key_column binary,   
+ value_column binary NOT NULL)
+USING kafka
+OPTIONS (   'group_id' = 'external_table_lh',    'topics' = 'my_topic')
+CONNECTION pipe_kafka;
+```
+
+
+
+### 创建 Table Stream
+
+在 Kafka 外部表上[创建一个 Table Stream](create-table-stream.md)，以便能够实时地捕获 Kafka 中的数据变化。
+
+```sql
+CREATE TABLE STREAM kafka_table_stream_pipe1 
+ON TABLE external_table_kafka
+WITH PROPERTIES (
+    'table_stream_mode' = 'append_only'
+
+);
+```
+
+* `kafka_table_stream_pipe1`：Table Stream 的名称。
+* `ON TABLE external_table_kafka`：指定基于之前创建的 Kafka 外部表创建 Table Stream。
+* `table_stream_mode='append_only'`：指定 Table Stream 的模式为仅追加，意味着只会捕获新增的数据行。
+
+
+
+创建完成后，可以通过以下查询来验证 Table Stream 中的数据：
+
+```sql
+SELECT CAST(value AS STRING) FROM kafka_table_stream_pipe1;
+```
+
+此查询将 Table Stream 中的 `value` 字段转换为字符串类型并返回，方便后续处理。
+
+### 创建目标表
+
+接下来，我们需要创建一个目标表，用于存储从 Kafka 导入的数据。
+
+```sql
+CREATE TABLE kafka_sink_table_1 (
+    a TIMESTAMP,
+    b STRING
+);
+```
+
+* `kafka_sink_table_1`：目标表的名称。
+* `a TIMESTAMP`：第一个字段，用于存储时间戳类型的数据。
+* `b STRING`：第二个字段，用于存储字符串类型的数据。
+
+### 创建 Pipe
+
+最后，使用 Pipe 将 Table Stream 中的数据持续导入到目标表中。
+
+```sql
+CREATE PIPE kafka_pipe_stream
+VIRTUAL_CLUSTER = 'test_alter'
+AS
+COPY INTO kafka_sink_table_1
+FROM (
+    SELECT CURRENT_TIMESTAMP(), CAST(value AS STRING) FROM kafka_table_stream_pipe1
+);
+```
+
+* `kafka_pipe_stream`：Pipe 的名称。
+* `VIRTUAL_CLUSTER = 'test_alter'`：指定使用的虚拟集群为 名称，
+* `COPY INTO kafka_sink_table_1`：将数据复制到目标表 `kafka_sink_table_1` 中。
+* `SELECT CURRENT_TIMESTAMP(), CAST(value AS STRING) FROM kafka_table_stream_pipe1`：从 Table Stream 中选择数据，将当前时间戳和转换为字符串的 `value` 字段作为目标表的两列数据。
+
+其他可设置的属性
+- `INITIAL_DELAY_IN_SECONDS`:首个作业调度延迟，选填项（默认 0 秒）
+- `BATCH_INTERVAL_IN_SECONDS`：（可选）设置批处理间隔时间，默认值为60秒。
+- `BATCH_SIZE_PER_KAFKA_PARTITION`：（可选）设置每个Kafka分区的批处理大小，默认值为500,000条。
+- `MAX_SKIP_BATCH_COUNT_ON_ERROR`：（可选）设置在出错时跳过的批次的最大重试次数，默认值为30。
+- `RESET_KAFKA_GROUP_OFFSETS`：（可选）设置启动pipe时Kafka的初始点位,不支持修改。可选值为`latest`、`earliest`、`none`、`valid`、`${TIMESTAMP\_MILLISECONDS}`
+    - 'none' 默认无操作
+    - 'valid' 检查 group 中的当前点位是否过期，将过期的 partition 点位重置到当前的 earliest 
+    - 'earliest' 重置到当前 earliest
+    - 'latest' 重置到当前 latest    
+    - '${TIMESTAMP\_MILLISECONDS}' 重置到毫秒时间戳对应点位，如 '1737789688000'（2025-01-25 15:21:28）
+
+## 三、验证结果
+
+可以通过查询目标表来验证数据是否成功导入：
+
+```sql
+SELECT * FROM kafka_sink_table_1;
+```
+
+同时，可以查看 Pipe 的运行状态，确保其正常工作：
+
+```sql
+SHOW PIPES;
+```
+
+此命令将列出所有已创建的 Pipe 及其状态信息，包括是否在运行、上次运行时间等。
+## 四、状态监控与管理
+### 查看Kafka消费延迟
+通过 DESC PIPE 命令。如下面的pipe_latency中的json字符串。
+    - lastConsumeTimestamp：上一次消费的点位
+    - offsetLag：Kafka数据得堆积量
+    - timeLag：消费延迟，计算为当前时间减去上一次消费的点位。当Kafka消费异常时值为-1
+

+### 查看Pipe运行历史
+由于每次都是Pipe下发copy执行，你可以在作业历史中查看所有操作。通过[作业历史](<web-job-history.md>)中的query_tag来筛选，所有的pipe执行的copy作业都会在query_tag打上标签，格式为`pipe.``workspace_name``.schema_name.pipe_name`，方便追踪和管理。
+
+### 停止和启动Pipe
+- 暂停Pipe
+```
+ALTER PIPE pipe_name SET PIPE_EXECUTION_PAUSED = true;
+```
+- 启动Pipe
+```
+ALTER PIPE pipe_name SET PIPE_EXECUTION_PAUSED = false;
+```
+
+### 修改Pipe属性
+您可以修改 PIPE 的属性，但每次只能修改一个属性。如果需要修改多个属性，则需要多次执行 `ALTER` 命令。以下是可修改的属性及其语法：
+
+```SQL
+ALTER PIPE pipe_name SET 
+    [VIRTUAL_CLUSTER = 'virtual_cluster_name'],
+    [BATCH_INTERVAL_IN_SECONDS=''],
+    [BATCH_SIZE_PER_KAFKA_PARTITION=''],
+    [MAX_SKIP_BATCH_COUNT_ON_ERROR=''],
+    [COPY_JOB_HINT='']
+```
+案例
+```
+--修改计算集群
+ALTER PIPE pipe_name SET VIRTUAL_CLUSTER = 'default'
+--设置COPY_JOB_HINT
+ALTER PIPE pipe_name SET COPY_JOB_HINT='{"cz.mapper.kafka.message.size": "2000000"}'
+
+```
+**注意**
+- 不支持修改COPY语句逻辑，如果您需要修改请删除Pipe重新创建
+- 当你修改 Pipe 的 `COPY_JOB_HINT` 时，新的设置会覆盖原有的 hints。因此，如果你的 Pipe 中已经存在某些 hints，例如 `{"cz.sql.split.kafka.strategy":"size"}`，当你再次添加新的 hints 时，必须将所有需要的 hints 一起设置，否则原有的 hints 会被新设置的 hints 覆盖。多个参数之间使用逗号分隔

+# 使用Pipe自动采集Kafka数据
+
+## 概述
+
+Pipe 是 Lakehouse 提供的**持续数据摄取**解决方案，专门用于从 Kafka 自动、持续地将数据导入到 Lakehouse 表中。Pipe 会创建持久的消费者组，保持消费位置，并按照设定的调度策略持续运行。
+
+## Kafka Pipe语法
+
+```SQL
+-- 从Kafka创建Pipe的语法
+CREATE PIPE [ IF NOT EXISTS ] <pipe_name>
+    VIRTUAL_CLUSTER = 'virtual_cluster_name'
+    [INITIAL_DELAY_IN_SECONDS='']
+    [BATCH_INTERVAL_IN_SECONDS='']
+    [BATCH_SIZE_PER_KAFKA_PARTITION='']
+    [MAX_SKIP_BATCH_COUNT_ON_ERROR='']
+    [RESET_KAFKA_GROUP_OFFSETS='']
+    [COPY_JOB_HINT='']
+AS <copy_statement>;
+```
+
+* `<pipe_name>`：Pipe 对象的名称，用于管理和监控
+* `VIRTUAL_CLUSTER`：指定执行 Pipe 任务的虚拟集群名称
+* `INITIAL_DELAY_IN_SECONDS`:首个作业调度延迟，选填项（默认 0 秒）
+* `BATCH_INTERVAL_IN_SECONDS`：（可选）设置批处理间隔时间，默认值为60秒。
+* `BATCH_SIZE_PER_KAFKA_PARTITION`：（可选）设置每个Kafka分区的批处理大小，默认值为500,000条。
+* `MAX_SKIP_BATCH_COUNT_ON_ERROR`：（可选）设置在出错时跳过的批次的最大重试次数，默认值为30。
+* `RESET_KAFKA_GROUP_OFFSETS`：（可选）控制 Pipe 启动时从 Kafka 的哪个位置开始消费数据只支持启动时设置，如果不设置此参数且消费者组无历史位置信息，将使用 Kafka 的 [auto.offset.reset](https://kafka.apache.org/documentation/#consumerconfigs_auto.offset.reset) 配置（默认为 `latest`）。支持的可选值如下
+  * 'none'无操作，如果设置为none则会使用[auto.offset.reset](https://kafka.apache.org/documentation/#consumerconfigs_auto.offset.reset)
+  * 'valid' 检查 group 中的当前点位是否过期，将过期的 partition 点位重置到当前的 earliest
+  * 'earliest' 重置到当前 earliest
+  * 'latest' 重置到当前 latest
+  * '${TIMESTAMP\_MILLISECONDS}' 重置到毫秒时间戳对应点位，如 '1737789688000'（2025-01-25 15:21:28）
+
+## 在 Pipe 中使用 READ\_KAFKA
+
+如果您想临时探查则可以使READ_KAFKA函数参考文档[READ_KAFKA函数](<sql_functions/table_functions/read_kafka.md>)，在 Pipe 的 COPY 语句中使用 `READ_KAFKA` 时，有以下**重要差异**：
+
+### 参数传递规则
+
+```sql
+-- Pipe 中的 READ_KAFKA 语法
+read_kafka (
+    'bootstrap_servers',     -- 必填：Kafka 集群地址
+    'topic',                 -- 必填：Topic 名称
+    '',                      -- 必填：Topic 模式（暂不支持，填空字符串）
+    'group_id',              -- 必填：持久消费者组 ID
+    '',                      -- 留空：起始位置由 Pipe 自动管理
+    '',                      -- 留空：结束位置由 Pipe 自动管理  
+    '',                      -- 留空：起始时间戳由 Pipe 自动管理
+    '',                      -- 留空：结束时间戳由 Pipe 自动管理
+    'raw',                   -- Key 格式
+    'raw',                   -- Value 格式
+    0,                       -- 最大错误数
+    map()                    -- Kafka 配置参数
+)
+```
+### 关键区别
+
+| 特性     | READ\_KAFKA 函数（独立使用）     | READ\_KAFKA（在 Pipe 中） |
+| ------ | ------------------------ | --------------------- |
+| 消费者组   | 临时，执行完即销毁                | 持久，保持消费位置状态           |
+| 位置管理   | 手动指定 starting\_offsets 等 | Pipe 自动管理，位置参数必须留空    |
+| 执行方式   | 一次性查询                    | 持续调度执行                |
+| 默认起始位置 | earliest（探查历史数据）         | latest（处理新数据）         |
+
+### 最佳实践

+# 概述
+
+Pipe 是 Lakehouse 平台中的一项强大数据导入功能，它允许用户以固定频率直接从对象存储中读取数据并导入到 Lakehouse。通过实现文件检测机制，Pipe 支持以微批处理方式加载文件，使得用户能够迅速访问最新数据。特别适合需要实时或近实时数据处理的场景。
+
+## Pipe 工作原理
+
+1. **文件检测**：
+
+   1. **EVENT\_NOTIFICATION\_MODE**：需要开通消息服务，利用阿里云消息服务通知Lakehouse新文件的上传，目前只支持阿里云OSS和AWS S3。
+   2. **LIST\_PURGE模式**：定期扫描目录，同步未记录的文件，并在同步后删除原文件。
+
+2. **COPY 语句**：定义数据文件的源位置和目标表，支持多种文件格式。
+
+3. **自动化加载**：自动检测新文件并执行COPY语句。
+
+4. **避免导入重复机制**：为了避免重复导入，load\_history函数记录了当前表的copy导入历史文件。Pipe在执行时会根据load\_history表名和导入文件名称去重，确保不会重复导入已有的文件。如果需要导入已记录的文件，可以手动执行copy命令。load\_history记录目前会保留7天。
+
+5. **Pipe导入作业历史**：由于每次都是Pipe下发copy执行，你可以在作业历史中查看所有操作。通过作业历史中的query\_tag来筛选，所有的pipe执行的copy作业都会在query\_tag打上标签，格式为`pipe.``workspace_name``.schema_name.pipe_name`，方便追踪和管理。
+
+## 使用场景
+
+* **实时数据同步**：当你的数据存储在对象存储中，且需要频繁同步以及时获取最新数据。
+* **成本优化**：在对象存储上进行数据导入导出可以避免产生网络公网流量费用。特别是在相同region下，可以指定对象存储为内网传输，进一步降低成本。
+
+## 注意事项
+
+* 使用EVENT\_NOTIFICATION\_MODE时，需要使用role arn授权方式创建存储连接。
+* LIST\_PURGE模式支持密钥和role arn两种授权方式。
+* **文件大小推荐**：gzip 压缩文件建议在 50MB。CSV、PARQUET 未压缩文件建议在 128MB 到 256MB 之间。
+* **数据加载顺序**：**数据加载无法保证严格有序**。
+* **Pipe 延迟**:Pipe加载时间受多种因素影响，包括文件格式、大小和COPY语句的复杂性。
+* **Pipe 与 Volume 对应关系**： 每个 Pipe 需对应独立的 Volume，不可复用。
+- 不支持修改COPY语句逻辑，如果您需要修改请删除Pipe重新创建
+- 当你修改 Pipe 的 `COPY_JOB_HINT` 时，新的设置会覆盖原有的 hints。因此，如果你的 Pipe 中已经存在某些 hints，例如 `{"cz.sql.split.kafka.strategy":"size"}`，当你再次添加新的 hints 时，必须将所有需要的 hints 一起设置，否则原有的 hints 会被新设置的 hints 覆盖。多个参数之间使用逗号分隔
+- PIPE中的COPY语句不支持files/regexp/subdirectory参数
+
+
+## 成本
+
+根据加载文件时使用的计算资源计费。
+## PIPE语法
+```SQL
+-- 从对象存储创建Pipe的语法
+CREATE PIPE [ IF NOT EXISTS ] <pipe_name>
+    VIRTUAL_CLUSTER = 'virtual_cluster_name'
+    INGEST_MODE='LIST_PURGE'|'EVENT_NOTIFICATION'
+    [COPY_JOB_HINT='']
+AS <copy_statement>;
+```
+- `<pipe_name>`：您要创建的Pipe对象的名称。
+- `VIRTUAL_CLUSTER`：指定虚拟集群的名称。
+- `INGEST_MODE`：设置为`LIST_PURGE`或`EVENT_NOTIFICATION`，以确定数据导入模式。
+- `COPY_JOB_HINT`：可选，Lakehouse保留参数
+- copy_statement：`<copy_statement>` 支持 中的中的文件参数都支持。当设置 `ON_ERROR=CONTINUE|ABORT` 参数时，可控制数据加载过程中遇到错误时的处理策略，且添加该参数后会返回导入文件列表：
+    * `CONTINUE`：跳过错误行，继续加载后续数据。适用于容忍部分错误，且要求最大限度完成数据加载的场景。目前，可忽略的错误仅限于文件不格式匹配的情况，例如命令中指定为 zip 压缩格式，而文件中存在 zstd 压缩格式。
+    * `ABORT`：立即终止整个`COPY`操作。适用于数据质量要求严格，任何错误都需要人工介入检查的场景。
+
+
+## 支持的文件格式
+
+参考[COPY INTO导入](copy-into-table.md)。
+
+## 使用PIPE加载案例
+
+### 使用扫描文件模式
+
+**具体使用步骤**
+
+步骤 1: 创建 connection 和 volume
+
+```SQL
+--创建连接用来连接对象存储
+CREATE STORAGE CONNECTION if not exists my_connection_exnet
+    TYPE OSS
+    ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com'
+    ACCESS_KEY = 'LTAI5tMmbq1Ty1xxxxxxxxx'
+    SECRET_KEY = '0d7Ap1VBuFTzNg7gxxxxxxxxxxxx'
+    COMMENT = 'OSS public endpoint';
+
+--创建volume, 用于映射对象存储目录
+CREATE EXTERNAL VOLUME pipe_volume
+    location 'oss://ossmy/autoloader/pipe/'
+    using connection my_connection_exnet
+    directory = (
+        enable=true,
+        auto_refresh=true
+    )
+    recursive=true;
+    
+```
+
+步骤 2: 单独执行copy命令看是否可以导入成功
+
+```SQL
+copy into pipe_purge_mode from volume pipe_volume(id int,col string) 
+using csv OPTIONS(
+  'header'='false'
+) ;
+```
+
+步骤 3: 使用上面的语句构建pipe对象
+
+```SQL
+create pipe volume_pipe_list_purge
+  VIRTUAL_CLUSTER = 'default'
+  --执行获取最新文件使用扫描文件模式
+  INGEST_MODE = 'LIST_PURGE'
+  as
+copy into pipe_purge_mode from volume pipe_volume(id int,col string) 
+using csv OPTIONS(
+  'header'='false'
+)
+--必须添加purge参数导入成功后删除数据 
+purge=true
+;
+```
+
+步骤 4: 查看pipe执行历史和已经导入的文件
+
+* 查看pipe copy作业执行情况
+
+通过作业历史中的query\_tag来筛选,所有的pipe执行的copy作业都会在query\_tag打上标签:格式为pipe.worksapce\_name.schema\_name.pipe\_name
+
+* 查看copy作业导入的历史文件
+
+```SQL
+select * from load_history('schema_name.table_name');
+```
+
+### 使用消息服务通知模式（只支持阿里云OSS和AWS S3）
+
+步骤 1: 开通阿里云消息服务 (MNS)
+
+1. 在阿里云控制台中开通消息服务 MNS。
+2. 配置 MNS 监听要同步的 OSS (Object Storage Service) 文件夹。[具体参考文档](https://help.aliyun.com/zh/mns/user-guide/create-a-rule-to-generate-oss-event-notifications?spm=a2c4g.11186623.0.i14)
+
+步骤 2: 授权 Lakehouse 读取 OSS
+具体方式参考使用role arn方式[阿里云存储连接创建](aliyun_storage_connection.md)授权 Lakehouse 读取对应 OSS Bucket 的权限。
+
+步骤 3: 授权 MNS 给 Lakehouse
+
+```
+ 在阿里云 RAM 控制台中，将 `AliyunMNSFullAccess` 权限授权给步骤二中的 Role，步骤二中案例为CzUDFRole
+```
+
+![](.topwrite/assets/image_1722602785678.png)
+
+步骤 4: 创建 Storage Connection
+
+```SQL
+CREATE STORAGE CONNECTION my_connection_exnet_role
+    TYPE oss
+    REGION = 'cn-hangzhou'  -- 根据 OSS 所在的区域选择
+    ROLE_ARN = 'acs:ram::...:role/czudfrole'  -- 替换为你的 Role ARN
+    ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com';  -- 根据 OSS 所在的区域选择 Endpoint
+```
+
+步骤 5: 创建 Volume
+
+```SQL
+CREATE EXTERNAL VOLUME my_volume_exnet_role
+    LOCATION 'oss://function-compute-my1/autoloader'  -- 替换为 OSS Bucket 的路径
+    USING connection my_connection_exnet_role
+    DIRECTORY = (
+        enable = TRUE,
+        auto_refresh = TRUE
+    )
+    RECURSIVE = TRUE;
+```
+
+步骤 6: 创建 Pipe
+
+```SQL
+CREATE PIPE my_pipe
+VIRTUAL_CLUSTER='TEST_VC'
+ALICLOUD_MNS_QUEUE = 'lakehouse-oss-event-queue'  -- 使用创建的 MNS 队列
+AS
+COPY INTO pipe_log_json FROM (
+    SELECT parse_json(col) json_col
+    FROM volume my_volume_exnet_role(col string)
+    USING csv
+    OPTIONS ('header' = 'false', 'sep' = '\001', 'quote' = '\0')
+);
+```

+# 使用Pipe持续导入数据
+
+>【预览发布】本功能当前处于公开预览发布阶段。
+
+## 概述
+
+Pipe 管道是云器 Lakehouse 用于流式数据采集的对象类型。使用 Pipe 可以持续增量地采集流式数据（如来自 Kafka），简化流式数据导入流程。
+
+Pipe 管道在定义时使用 COPY 命令表达读取外部数据源并写入目标表的语义。与单独的 COPY 命令的主要区别在于，Pipe 将自动持续调度 COPY 任务，维护和管理数据源的读取位置，持续不断地从数据源增量导入数据。
+
+使用 Pipe 进行流式数据自动导入的总体逻辑示意如下：
+
+![Pipe流式数据导入逻辑示意图](![](.topwrite/assets/image_1718767758845.png =541)
+
+## 数据源支持
+
+Pipe 管道提供了对数据源新变化数据的持续采集能力，当前数据源包括：
+
+* Kafka 数据源
+* 对象存储（如阿里云 OSS）
+
+## 管理使用Pipe
+
+Lakehouse 提供了一组操作命令用于管理 Pipe 管道：
+
+* `CREATE PIPE`
+* `DESC PIPE`
+* `SHOW PIPES`
+* `DROP PIPE`
+
+### 创建Pipe对象
+
+#### 创建Pipe对象读取Kafka数据源
+
+可使用SQL命令创建Pipe对象，语法如下：
+
+```SQL
+CREATE PIPE [ IF NOT EXISTS ] <name>
+  VIRTUAL_CLUSTER = '<virtual_cluster_name>'
+  [ BATCH_INTERVAL_IN_SECONDS = '<number>' ]
+  [ BATCH_SIZE_PER_KAFKA_PARTITION = '<number>' ]
+  [ COMMENT '<string_literal>' ]
+  AS <copy_statement>
+```
+
+参数说明：
+
+* `VIRTUAL_CLUSTER`：Pipe 提交 COPY 作业所用的 VC。必填项。
+* `BATCH_INTERVAL_IN_SECONDS`：作业生成周期。可选参数，默认 60 秒。
+* `BATCH_SIZE_PER_KAFKA_PARTITION`：作业最大单分区消息数。可选参数，默认 50 万。
+* `COMMENT`：添加注释。可选参数。
+* `COPY_STATEMENT`：使用 `COPY INTO` <table> 将数据导入到目标表。
+
+  * 对于 Kafka 数据源，在 SELECT 语句中将使用 `read_kafka` 表值函数读取 Kafka 消息数据。函数的参数说明请查看 `read_kafka` 函数说明。
+
+#### 创建Pipe读取对象存储数据源
+
+读取对象存储需要创建 VOLUME，同时需要开通阿里云消息服务。消息服务用于向 Pipe 发送对象存储事件，以触发 Pipe 执行。
+
+```SQL
+--创建pipe,其中ALICLOUD_MNS_QUEUE使用，刚刚创建的云消息服务mns队列lakehouse-oss-event-queue
+CREATE PIPE [ IF NOT EXISTS ] <name>
+  VIRTUAL_CLUSTER = '<virtual_cluster_name>'
+ALICLOUD_MNS_QUEUE = 'MNSQUEUE'
+as
+AS <copy_statement>
+```
+
+参数说明：
+
+* VIRTUAL_CLUSTER：Pipe 提交 COPY 作业所用的 VC。必填项。
+* `ALICLOUD_MNS_QUEUE`：消息队列名称。消息服务 MNS 可以将对象存储指定资源上产生的事件以消息的方式主动推送到指定的接收端。Pipe 接收到消息队列事件后触发执行，获取哪些文件是新增文件，然后触发 `COPY` 命令将数据导入到表中。
+
+### 查看Pipe列表及对象详情
+
+当前您可以使用 SQL 命令查看 Pipe 列表及对象详情。
+
+* 使用 `SHOW PIPES` 命令查看 Pipe 对象列表
+
+```
+列出当前 Schema 下的所有 Pipe
+SHOW PIPES;
+-- 列出指定 Schema 下的所有 Pipe
+SHOW PIPES IN SCHEMA schema_name;
+-- 列出指定 Workspace 下的所有 Pipe
+SHOW PIPES IN WORKSPACE workspace_name;
+```
+
+**说明**
+
+* `SHOW PIPES`：默认列出当前 Schema 下的 Pipe 对象。
+* `SHOW PIPES IN SCHEMA schema_name`：列出指定 Schema 中的所有 Pipe 对象。
+* `SHOW PIPES IN WORKSPACE workspace_name`：列出指定 Workspace 中的所有 Pipe 对象。
+
+* 使用 `DESC PIPE` 命令查看指定 Pipe 对象详细信息
+
+```SQL
+DESC PIPE <name>;
+```
+
+### 删除Pipe对象
+
+您可以使用 SQL 命令删除 Pipe 对象。
+
+```SQL
+DROP PIPE <name>;
+```
+
+## 约束与限制
+
+* 数据源是 Kafka 时：一个 Pipe 中只能有一个 `read_kafka` 函数。
+* 数据源是对象存储时：一个 Pipe 中只能有一个 Volume 对象。

+# Pipe 语法
+
+## 创建 Pipe 语法
+
+使用以下语法创建一个Pipe对象，以便自动化地将数据从对象存储导入到Lakehouse。
+
+# 创建Pipe对象以自动化数据导入Lakehouse
+
+本文档提供了创建Pipe对象的详细语法，以便自动化地将数据从对象存储或Kafka导入到Lakehouse。Pipe对象是一种强大的工具，可以帮助用户简化数据导入流程，并确保数据的高效流动。
+
+## 从对象存储导入数据
+
+要创建一个Pipe对象以从对象存储导入数据，可以使用以下语法：
+
+```SQL
+-- 从对象存储创建Pipe的语法
+CREATE PIPE [ IF NOT EXISTS ] <pipe_name>
+    VIRTUAL_CLUSTER = 'virtual_cluster_name'
+    INGEST_MODE='LIST_PURGE'|'EVENT_NOTIFICATION'
+    [COPY_JOB_HINT='']
+AS <copy_statement>;
+```
+
+* `<pipe_name>`：您要创建的Pipe对象的名称。
+* `VIRTUAL_CLUSTER`：指定虚拟集群的名称。
+* `INGEST_MODE`：设置为`LIST_PURGE`或`EVENT_NOTIFICATION`，以确定数据导入模式。
+* `COPY_JOB_HINT`：可选，Lakehouse保留参数
+- `IGNORE_TMP_FILE`:取值true|false,默认值true。支持过滤点开头和 _temporary 开头的文件或者目录文件参数。如 `s3://my_bucket/a/b/.SUCCESS，oss://my_bucket/a/b/_temporary/`或者`oss://my_bucket/a/b/_temporary_123/`
+- copy_statement：`<copy_statement>` 支持 中的中的文件参数都支持。当设置 `ON_ERROR=CONTINUE|ABORT` 参数时，可控制数据加载过程中遇到错误时的处理策略，且添加该参数后会返回导入文件列表：
+    * `CONTINUE`：跳过错误行，继续加载后续数据。适用于容忍部分错误，且要求最大限度完成数据加载的场景。目前，可忽略的错误仅限于文件不格式匹配的情况，例如命令中指定为 zip 压缩格式，而文件中存在 zstd 压缩格式。
+    * `ABORT`：立即终止整个`COPY`操作。适用于数据质量要求严格，任何错误都需要人工介入检查的场景。
+### 使用限制
+* Pipe 中的 COPY 语句不支持 files、regexp、subdirectory 参数。
+* **Pipe 与 Volume 对应关系**：每个 Pipe 需对应独立的 Volume，不可复用。
+
+
+
+### 使用说明
+
+* [使用Pipe持续导入对象存储数据](pipe-storage-object.md)
+
+## 从Kafka导入数据
+
+要创建一个Pipe对象以从Kafka导入数据，可以使用以下语法：
+
+```SQL
+-- 从Kafka创建Pipe的语法
+CREATE PIPE [ IF NOT EXISTS ] <pipe_name>
+    VIRTUAL_CLUSTER = 'virtual_cluster_name'
+    [BATCH_INTERVAL_IN_SECONDS='']
+   [ BATCH_SIZE_PER_KAFKA_PARTITION='']
+    [MAX_SKIP_BATCH_COUNT_ON_ERROR='']
+    [RESET_KAFKA_GROUP_OFFSETS='']
+    [COPY_JOB_HINT='']
+AS <copy_statement>;
+```
+- `<pipe_name>`：您要创建的Pipe对象的名称。
+- `VIRTUAL_CLUSTER`：指定虚拟集群的名称。
+- `INITIAL_DELAY_IN_SECONDS`:首个作业调度延迟，选填项（默认 0 秒）
+- `BATCH_INTERVAL_IN_SECONDS`：（可选）设置批处理间隔时间，默认值为60秒。
+- `BATCH_SIZE_PER_KAFKA_PARTITION`：（可选）设置每个Kafka分区的批处理大小，默认值为500,000条。
+- `MAX_SKIP_BATCH_COUNT_ON_ERROR`：（可选）设置在出错时跳过的批次的最大重试次数，默认值为30。
+- `RESET_KAFKA_GROUP_OFFSETS`：（可选）设置启动pipe时Kafka的初始点位，不支持使用Alter修改。可选值为`latest`、`earliest`、`none`、`valid`、`${TIMESTAMP\_MILLISECONDS}`
+    - 'none'：默认无操作。
+    - 'valid'：检查 group 中的当前点位是否过期，将过期的 partition 点位重置到当前的 earliest。
+    - 'earliest'：重置到当前 earliest。
+    - 'latest'：重置到当前 latest。
+    - '${TIMESTAMP\_MILLISECONDS}'：重置到毫秒时间戳对应点位，例如 '1737789688000'（2025-01-25 15:21:28）。
+
+### 使用说明
+
+* [使用read_kafka持续导入Kafka数据](pipe-kafka.md)
+* [使用Kafka Table Stream持续导入Kafka数据](pipe-kafka-table-stream.md)
+
+#### 暂停和启动 Pipe
+
+您可以控制 Pipe 的执行状态，以便于管理数据同步过程。
+
+* **暂停PIPE**：
+
+```SQL
+ALTER PIPE pipe_name SET PIPE_EXECUTION_PAUSED = true
+```
+
+* **启动PIPE**：
+
+```SQL
+ALTER PIPE pipe_name SET PIPE_EXECUTION_PAUSED = false
+```
+
+# 查看Pipe详情
+
+查看特定Pipe对象的详细信息。
+
+```SQL
+DESC PIPE [EXTENDED] <name>;
+```

+# Python任务使用实践
+
+任务开发模块中提供的Python任务，作为一种轻量级资源容器下的特定任务类型，专为运行Python代码而设计，提供了任务间环境隔离的功能，并具备基础的环境定制能力。本文介绍Python任务的一些使用实践。
+
+^
+
+### 运行环境和定制
+
+Python任务在系统预设的Pod环境中执行，预装的Python版本为Python 3（当前版本为3.9.2，未来可能会更新）。
+
+系统默认镜像中包含了一些常用的依赖包，以支持与云器 Lakehouse 的连接和数据访问，以及对阿里云 OSS 和腾讯云 COS 等对象存储服务的操作。这些依赖包包括但不限于：
+
+* clickzetta-connector
+* clickzetta-sqlalchemy
+* cos-python-sdk-v5
+* numpy
+* oss2
+* pandas
+* six
+* urllib2
+* ...
+
+为了满足特定的运行需求，Pod环境提供了有限的环境定制能力。您可以在 `/home/system_normal` 路径下进行自定义安装。以下是一个示例代码片段，展示了如何在Python环境中安装自定义安装包（第4行和第5行）并使用。请注意，Python任务执行完毕后，Pod环境将会被销毁，因此任何环境定制都不会被保留。
+
+```py
+import subprocess
+import sys
+
+subprocess.check_call([sys.executable, "-m", "pip", "install", "mysql-connector-python","--target", "/home/system_normal", "-i", "https://pypi.tuna.tsinghua.edu.cn/simple"])
+sys.path.append('/home/system_normal')
+
+import mysql.connector
+
+# 创建连接
+connection = mysql.connector.connect(
+    host='127.0.0.1',   # 数据库主机地址
+    user='****',       # 数据库用户名
+    password='***********', # 数据库密码
+    database='demo'  # 需要连接的数据库名称
+)
+
+# 创建游标
+cursor = connection.cursor()
+
+# 执行查询
+query = "show tables"  # 替换为你的 SQL 查询
+cursor.execute(query)
+
+# 获取查询结果
+results = cursor.fetchall()
+print("Query results:")
+for row in results:
+    print(row)
+
+# 关闭游标和连接
+cursor.close()
+connection.close()
+```
+
+^
+
+### 运行资源大小调整
+
+默认情况下，Pod 提供 0.5 个 CPU 核和 512 MB 内存资源。如果需要，您可以在任务的调度配置中通过以下参数调整资源分配：
+
+* `pod.limit.cpu`：设置 CPU 核数。必须是大于 0 的数值，如 1，最高可设置为 4。默认值为 0.5。
+* `pod.limit.memory`：设置内存大小，格式为数值加上单位，如 2G，最高可设置为 8G。默认值为 512M。
+
+  ![](.topwrite/assets/image_1718339259582.png =513)
+
+通过合理配置这些参数，您可以确保 Python 任务拥有足够的资源来满足不同的计算需求，同时避免资源浪费。
+
+^
+
+### 更多使用案例
+
+#### 使用 Python Database API 查询 Lakehouse 数据
+
+```py
+from clickzetta import connect
+
+# 建立连接
+conn = connect(
+    username='your_username',
+    password='your_password',
+    service='region_id.api.clickzetta.com',
+    instance='your_instance',
+    workspace='your_workspace',
+    schema='public',
+    vcluster='default'
+)
+
+# 创建游标对象
+cursor = conn.cursor()
+
+# 执行 SQL 查询
+cursor.execute('SELECT * FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live LIMIT 10;')
+
+# 获取查询结果
+results = cursor.fetchall()
+for row in results:
+    print(row)
+```
+
+^
+
+#### 使用 SQLAlchemy 接口查询 Lakehouse 数据
+
+```py
+from sqlalchemy import create_engine
+from sqlalchemy import text
+
+# 创建 ClickZetta Lakehouse 的 SQLAlchemy 引擎实例
+engine = create_engine(
+    "clickzetta://username:password@instance.api.clickzetta.com/workspace?schema=schema&vcluster=default"
+)
+
+# 执行 SQL 查询
+sql = text("SELECT * FROM ecommerce_events_multicategorystore_live;")
+
+# 使用引擎执行查询
+with engine.connect() as conn:
+    result = conn.execute(sql)
+    for row in result:
+        print(row)
+```
+
+#### 使用 Python 批量上传数据到 Lakehouse
+
+```py
+from clickzetta import connect
+
+conn = connect(
+    username='your_username',
+    password='your_password',
+    service='region_id.api.clickzetta.com',
+    instance='your_instance',
+    workspace='your_workspace',
+    schema='public',
+    vcluster='default'
+)
+
+bulkload_stream = conn.create_bulkload_stream(schema='public', table='bulkload_test')
+
+writer = bulkload_stream.open_writer(0)
+for index in range(1000000):
+    row = writer.create_row()
+    row.set_value('i', index)
+    row.set_value('s', 'Hello')
+    row.set_value('d', 123.456)
+    writer.write(row)
+writer.close()
+
+bulkload_stream.commit()
+```

+# 云器Lakehouse计费说明
+
+## 1. 计费方式概述
+
+云器Lakehouse是基于云原生建设的一体化数据平台，平台会记录你在数据集成、数据分析、存储和网络传输等场景下消耗的资源，并按照计算、存储、网络三种类型，根据服务发生的云平台和地域，向您收取相应的费用。
+
+云器Lakehouse的计费主要基于以下几个方面：
+
+* **计算资源**：计算资源的计费单元为**CRU**\***时**，1CRU\*时代表在每个云平台的每个服务区域以同样的算力运行1小时。你在云器Lakehouse使用同步型、分析型、通用型计算集群所进行数据集成或数据分析，使用Python、Shell脚本处理的任务，以及系统自动处理的自动物化视图（Auto\_MV)、数据压缩、作业任务调度等操作均会产生计算资源的使用。我们会根据实际消耗的算力使用量进行计量计费。
+* **存储资源**：存储资源的计费单元为GiB，根据你在云器Lakehouse上实际使用的存储容量进行计费。以下场景会占用存储容量：
+  1）在Lakehouse中以表、物化视图等形式存储的数据；
+  2）数据表生命周期内已删除但未清理的数据；
+  3）查询结果的缓存。其中第2、第3项当前仅计量，暂免收费。
+* **数据传输**：数据传输的计费单元为GB，根据数据传输的量进行计费。以下场景会产生数据传输费用：通过公网的数据查询，数据查询结果的全量下载，以云器Lakehouse为数据源向其他数据源传输数据。数据传输流量可能通过Internet、跨VPC的网络连接、专线或者其他网络连通方式产生。其中针对Internet网络流量，仅计量从云器Lakehouse流出的数据传输量，上传数据至云器Lakehouse不收费。
+
+## 2. 计费方式
+
+**按需计费**
+
+在云器Lakehouse中，各类资源均是灵活扩展、按需使用的，你只需按照实际使用的资源量进行付费。其中：
+
+**计算资源**计费按秒统计每一台计算集群实例的开机至关机的时间，按照CRU进行计量，并换算成法定货币为单位的账单；
+
+**存储资源**以全天所有数据（包含数据表当前数据、历史版本数据，查询结果缓存等）存储容量的平均值计费；
+
+**网络传输**费用按照实际产生的网络流量计费，其中Internet网络流量费用以流出Lakehouse方向的流量计费。
+
+由于不同云平台、不同区域下，资源的价格不同，计算、存储和网络每单位的单价也会存在差异。具体价格请参考“云器Lakehouse价格表”，以系统内实际账单为准。
+
+你可以通过“管理中心”-“计费账单”页面查看资源使用情况及费用明细。其中计算资源和数据传输费用每小时进行一次计量和扣费，存储资源以全天24小时采样的容量平均值，每天进行一次计量和扣费。
+
+**包年预付费**
+
+云器Lakehouse也可为企业客户提供指定资源规格，按年预付费的计费方式。包年预付费时，计算和存储资源的单价可提供相应折扣。详情请联系云器销售人员。
+
+## 3. 计费原理
+
+### 3.1 计算资源计费
+
+计算资源的计费项包括：通用型计算集群、分析型计算集群、同步型计算集群、调度任务和serverless作业5种。各计费项的计费原理如下：
+
+* **通用型计算集群**
+
+当通用型计算集群启动至“运行中”状态，即开始根据集群的规格大小和实例数，产生对应的CRU消耗，当该计算集群进入“停止中”状态，则停止产生CRU消耗。
+
+^
+
+通用型计算集群的规格及对应的每小时CRU消耗如下：
+
+| **计算集群规格** | **每小时CRU消耗**（CRU\*时） |
+| ---------- | -------------------- |
+| 1          | 1                    |
+| 2          | 2                    |
+| 3          | 3                    |
+| 4          | 4                    |
+| 5          | 5                    |
+| ...        | ...                  |
+| 256        | 256                  |
+
+* **分析型计算集群**
+
+分析型计算集群的计费原理与通用型计算集群相同，从“运行中”状态的开始时间开始计量，直至进入“停止中”状态。
+
+分析型计算集群在规格的基础上，增加了“实例”的弹缩。当通过自动弹缩扩容出1个实例，即会增加一个同等规格计算集群的消耗。
+
+下表为分析型计算集群1到5个实例时，每小时CRU消耗，更多实例数以此类推：
+
+| **计算集群规格** | **1个实例**&#xA;**每小时消耗** | **2个实例**&#xA;**每小时消耗** | **3个实例**&#xA;**每小时消耗** | **4个实例**&#xA;**每小时消耗** | **5个实例**&#xA;**每小时消耗** |
+| ---------- | ---------------------- | ---------------------- | ---------------------- | ---------------------- | ---------------------- |
+| 1          | 1 CRU\*时               | 2 CRU\*时               | 3 CRU\*时               | 4 CRU\*时               | 5 CRU\*时               |
+| 2          | 2 CRU\*时               | 4 CRU\*时               | 6 CRU\*时               | 8 CRU\*时               | 10 CRU\*时              |
+| 4          | 4 CRU\*时               | 8 CRU\*时               | 12 CRU\*时              | 16 CRU\*时              | 20 CRU\*时              |
+| 8          | 8 CRU\*时               | 16 CRU\*时              | 24 CRU\*时              | 32 CRU\*时              | 40 CRU\*时              |
+| 16         | 16 CRU\*时              | 32 CRU\*时              | 48 CRU\*时              | 64 CRU\*时              | 80 CRU\*时              |
+| 32         | 32 CRU\*时              | 64 CRU\*时              | 96 CRU\*时              | 128 CRU\*时             | 160 CRU\*时             |
+| 64         | 64 CRU\*时              | 128 CRU\*时             | 192 CRU\*时             | 256 CRU\*时             | 320 CRU\*时             |
+| 128        | 128 CRU\*时             | 256 CRU\*时             | 384 CRU\*时             | 512 CRU\*时             | 640 CRU\*时             |
+| 256        | 256 CRU\*时             | 512 CRU\*时             | 768 CRU\*时             | 1024 CRU\*时            | 1280 CRU\*时            |
+
+* **同步型计算集群**
+
+同步型计算集群主要用于提交离线集成和实时集成任务。多个集成任务可提交至同1个同步型计算集群中，以复用资源。同步型计算集群的计费原理与通用型计算集群相同，从“运行中”状态的开始时间开始计量，直至进入“停止中”状态。当前“同步型计算集群”处于试运行状态，暂时以同步型计算集群中执行的数据集成作业为单位，分别计入至“离线集成”和“实时集成”两个计费项中。“同步型计算集群”正式运行后，数据集成费用合并至同步型计算集群计费项中。
+
+同步型计算集群的规格及对应的每小时CRU消耗如下：
+
+| **计算集群规格** | **每小时CRU消耗** |
+| ---------- | ------------ |
+| 0.25       | 0.25 CRU\*时  |
+| 0.5        | 0.5 CRU\*时   |
+| 1          | 1 CRU\*时     |
+| 2          | 2 CRU\*时     |
+| 3          | 3 CRU\*时     |
+| 4          | 4 CRU\*时     |
+| 5          | 5 CRU\*时     |
+| ...        | ...          |
+| 256        | 256 CRU\*时   |
+
+* **任务调度**
+
+任务调度包含两个场景：运行python、shell等脚本，以及离线或实时数据集成任务中的作业提交和调度管理。
+
+运行python、shell等脚本时，系统会根据脚本运行的资源配置，启动对应的计算资源。以启动执行脚本的计算资源为开始，脚本执行结束为终止，计量这个时间段内使用的计算资源，以CRU\*时为单位生成计费账单。
+在离线数据集成任务运行时，云器Lakehouse会提供少量计算资源用于作业提交和调度管理，这部分资源会在离线集成任务启动时开始使用（作业排队等待过程中不会消耗），并在离线集成任务进行时持续存在。因此，该计算资源的消耗会被计量，并以CRU\*时为单位生成计费账单。
+在实时数据集成任务运行时，云器Lakehouse会提供少量计算资源用于作业提交和调度管理，这部分资源会在实时集成任务启动时使用，在任务正式运行后结束。在这段时间内的计算资源消耗会被计量，并以CRU\*时为单位生成计费账单。
+
+* **Serverless作业**
+
+Serverless作业指无需用户主动创建计算集群实例，而由云器Lakehouse提供公共计算资源处理客户计算需求的作业统称。包含查询作业调度、数据压缩、自动物化视图等。
+
+### 3.2 存储资源计费
+
+存储费用根据您在Lakehouse平台实际使用的存储容量进行计量计费。当您在Lakehouse数仓中写入数据后，写入的数据及其部分元数据信息即在Lakehouse中占用存储容量。Lakehouse将统计您的数据实际占用的存储用量，于1天之内多次采样，并以当天采样存储容量的平均值，作为当天的存储容量计量数值，进行计量计费。
+
+当你使用Lakehouse的Time Travel功能时，为了保障数据的多版本、可恢复，Lakehouse会自动为您的数据进行多版本备份存储。此时产生的多版本备份数据将产生相应存储费用，以存储容量单价收费。
+
+当你进行SQL查询时，为降低重复查询的计算资源消耗，会对查询结果进行缓存，以存储成本换取计算资源的节省。这部分存储使用会计入“结果缓存（Result Cache）”，以存储容量单价收费。
+
+### 3.3 数据传输计费
+
+当你使用数据集成等功能，批量从Lakehouse通过公网下载、导出数据时，会产生Internet网络传输费用。Internet网络传输以实际产生的传输数据量进行计量，并计算费用。
+
+你从其他数据源通过Internet网络向Lakehouse上传数据产生的网络传输流量，不会产生网络传输费用。
+
+如果你使用了专线、Private Link或其他网络产品实现跨云厂商、跨地域或跨VPC网络打通时，网络打通本身会产生费用。这部分费用根据网络打通方式不同，产生在云器Lakehouse侧的由云器收取，在你的云平台账号中产生的费用由云平台直接收取。
+
+### 3.4 其他云资源计费
+
+云器Lakehouse在进行元数据管理，解析sql语句、生成查询计划、调度和分配查询任务，以及对数据文件进行合并、清理等操作时，均会消耗云资源。云器Lakehouse会对这些云资源的消耗进行计量，当前限时免费。开始收费前1个月将提前通知。

+
+## 5. 常见场景下的费用示例
+
+**通用型计算集群费用示例**
+
+以阿里云上海企业版服务实例为例：
+
+* 一个规格为2CRU的通用型计算集群，运行1小时，CRU\*时单价为3.5元，该计算集群运行1小时的费用为： 1小时\*2CRU\*3.5元/CRU\*时 = 7元
+* 一个规格为1CRU的通用型计算集群，运行1分20秒，CRU\*时单价为3.5元，该计算集群运行产生的费用为：1.33分钟/60分钟\*1CRU\*3.5元/CRU\*时=0.078元
+* 一个规格为1CRU的通用型计算集群，运行30秒，CRU\*时单价为3.5元，该计算集群运行产生的费用为：0.5分钟/60分钟\*1CRU\*3.5元/CRU\*时=0.029元 。
+
+**分析型计算集群费用示例**
+
+以阿里云上海企业版服务实例为例：
+
+* 一个规格为2CRU的分析型集群，分别以1个实例运行了30分钟，又以2个实例运行了30分钟，当CRU\*时单价为3.5元，该计算集群运行产生的费用为：
+
+  30分钟/60分钟\*1CRU\*1个实例\*3.5元/CRU\*时 + 30分钟/60分钟\*1CRU\*2个实例\*3.5元/CRU\*时 = 1.75元 + 3.5元 = 5.25元
+
+**同步型计算集群价格费用示例**
+
+以阿里云上海企业版服务实例为例：
+
+* 一个规格为2CRU的同步型集群，运行1小时，当CRU\*时单价为3.5元，该计算集群运行1小时的费用为： 1小时\*2CRU\*3.5元/CRU\*时 = 7元
+
+**离线集成任务费用示例**
+
+离线集成任务不单独收费，而是收取任务提交至的同步型计算集群的运行费用。离线集成任务可自动唤起同步型计算集群。一般估算离线集成任务时，可按照：5个单并发的离线集成任务可用满一个规格为0.25的同步型计算集群资源来估算离线集成任务。
+
+* 假设阿里云上海一个企业版服务实例的一个单并发离线集成任务运行10分钟，其消耗的算力约为：1/5 CRU \* 10分钟/60分钟 = 0.033 CRU\*时;
+* 因离线集成任务会唤起同步型计算集群，假设阿里云上海一个企业版服务实例的同步型计算集群的规格为1 CRU，10分钟任务结束后自动关闭，则产生的费用为：1CRU\*10分钟/60分钟\*3.5元/CRU\*时 = 0.58元；
+
+此时该规格为1 CRU的同步型计算集群还未用满，再提交4个单并发离线集成任务，假设均运行10分钟，其产生的费用仍为 0.58元。因此，尽量复用同步型计算集群的资源，同时避免使用过大规格的同步型计算集群能有效节省计算资源费用。
+
+**实时集成任务费用示例**
+
+实时集成任务不单独收费，而是收取任务提交至的同步型计算集群的运行费用。实时集成任务需要将其所在的同步型计算集群一直保持“运行”状态。因此需要选择尽量贴近实时集成任务所需的资源量创建同步型计算集群规格，避免资源浪费。可按照：16个单并发的实时集成任务可用满一个规格为1CRU的同步型计算集群资源来估算。
+
+**Python脚本任务费用示例**
+
+Python脚本任务执行时，会根据任务执行时长和消耗的计算资源进行计费。一般情况下，一个Python脚本执行1小时时，所使用的计算资源为0.125 CRU\*小时。
+
+* 假设阿里云上海一个企业版服务实例的一个Python脚本任务执行时间为10分钟，其产生的费用为：0.125CRU\*时\*10分钟/60分钟\*3.5元/CRU\*时=0.073元。
+
+**存储容量费用示例**
+
+* 假设在阿里云上海一个企业版服务实例的工作空间下，全天的存储容量低点为910GiB，高点1100GiB，全天平均值为1000GiB，则当天存储容量为：1000 GiB \* 0.12元/GiB/月 /30天 = 4元
+
+**网络传输价格示例**
+
+* 假设在阿里云上海一个企业版服务实例下，1小时产生的Internet下行流量为10 GB，则该小时的Internet网络传输费用为：10GB\*0.8元/GB=8元

+
+1. **ENFORCED | NOT ENFORCED**：指定是否强制执行约束。ENFORCED表示强制执行约束，NOT ENFORCED表示不强制执行约束。
+2. **DEFERRABLE | NOT DEFERRABLE**：指定延迟执行和非延迟执行。DEFERRABLE表示可以延迟执行约束，NOT DEFERRABLE表示立即执行约束。
+3. **INITIALLY { DEFERRED | IMMEDIATE** }：指定校验的时机。如果约束属性为NOT DEFERRABLE，则只能是INITIALLY IMMEDIATE。
+
+### 使用示例
+
+假设我们有一个订单表`orders`，其中包含以下字段：
+
+- `order_id`：订单ID，为主键。
+- `customer_id`：客户ID，为外键。
+- `order_date`：订单日期。
+- `total_amount`：订单总金额。
+
+我们可以为`orders`表定义以下约束：
+
+```sql
+CREATE TABLE orders (
+  order_id INT PRIMARY KEY ENFORCED,
+  customer_id INT REFERENCES customers DEFERRABLE INITIALLY DEFERRED,
+  UNIQUE (customer_id, order_date) ENFORCED
+);
+```
+
+在这个例子中，我们为`order_id`指定了ENFORCED属性，以确保每个订单都有一个唯一的ID。对于`customer_id`，我们使用了DEFERRABLE和INITIALLY DEFERRED属性，允许在插入数据时暂时违反外键约束。最后，我们为`customer_id`和`order_date`定义了一个唯一约束，以确保每个客户在同一天只能有一个订单。
+
+## 扩展的约束状态
+
+Clickzetta Lakehouse扩展的约束状态主要用于主键、外键和唯一键。这些约束状态包括：
+
+1. **ENABLE | DISABLE**：指定约束是禁用还是启动。ENABLE表示启动约束，DISABLE表示禁用约束。
+2. **VALIDATE | NOVALIDATE**：指定是否验证表上已有的数据，并创建索引。VALIDATE表示需要验证并创建索引，NOVALIDATE表示不需要验证和创建索引。
+3. **RELY | NORELY**：当指定NOVALIDATE为RELY时，查询优化器会使用此属性，提高查询性能。
+
+### 使用示例
+
+假设我们有一个销售记录表`sales`，其中包含以下字段：
+
+- `sale_id`：销售记录ID，为主键。
+- `product_id`：产品ID，为外键。
+- `sale_date`：销售日期。
+- `amount`：销售金额。
+
+我们可以为`sales`表定义以下约束：
+
+```sql
+CREATE TABLE sales (
+  sale_id INT PRIMARY KEY ENABLE VALIDATE RELY,
+  product_id INT REFERENCES products DISABLE NOVALIDATE NORELY
+);
+```
+
+在这个例子中，我们为`sale_id`指定了ENABLE、VALIDATE和RELY属性，以确保每个销售记录都有一个唯一的ID，并在插入数据时验证外键约束。对于`product_id`，我们使用了DISABLE、NOVALIDATE和NORELY属性，表示在插入数据时不验证外键约束，同时查询优化器可以提高查询性能。
+
+## 云器Lakehouse约束属性
+
+云器Lakehouse约束属性为ENABLE VALIDATE RELY，强制执行约束校验。需要注意的是，这种约束属性只支持使用Java SDK进行写入，不支持使用SQL进行插入。
+
+### 使用示例
+
+假设我们有一个用户表`users`，其中包含以下字段：
+
+- `user_id`：用户ID，为主键。
+- `username`：用户名。
+- `email`：电子邮件地址。
+
+我们可以使用Java SDK为`users`表定义以下约束：
+
+```java
+Table table = session.getTable("users");
+TableSchema schema = table.getSchema();
+PrimaryKeyConstraint primaryKeyConstraint = new PrimaryKeyConstraint("user_id");
+schema.addConstraint(primaryKeyConstraint);
+UniqueConstraint uniqueConstraint = new UniqueConstraint("username");
+schema.addConstraint(uniqueConstraint);
+session.createTable("users", schema, true);
+```
+
+在这个例子中，我们使用Java SDK创建了一个`users`表，并为其定义了一个主键约束和一个唯一约束。这些约束将强制执行，确保每个用户都有一个唯一的ID和用户名。由于使用了云器Lakehouse约束属性，我们无法通过SQL插入数据，只能使用Java SDK进行写入。

+# lakehouse 主键使用说明
+
+## 主键约束概述
+
+**主键（PRIMARY KEY**） 用于确保表中每条记录的唯一性。在大数据场景下，由于数据量通常非常庞大，为了保证数据的唯一性而对所有 key 进行逐一检查是不现实且低效的，因此一般不推荐在大数据环境中使用主键约束。然而，Lakehouse 仍提供了对主键的支持，以便在特定场景下满足数据完整性的需求。在Lakehouse架构中，定义了主键的表在进行实时数据写入时，系统将自动根据主键值进行数据去重，这对于变更数据捕获（CDC）场景尤为重要。例如，您可以实时地将MySQL数据库的binlog日志同步到Lakehouse，确保数据的一致性。设置完主键需要通过[实时数据接口](java_reference/realtime-upload.md)来处理数据。在CDC实时写入过程中，系统将依据主键自动进行数据去重，以维护数据的准确性和完整性。
+
+## lakehouse 主键支持及默认行为
+
+lakehouse 支持两种直接指定 primary key 的方式，且在默认情况下，其行为设置为 `ENABLE VALIDATE RELY`。这意味着，当您在创建表时指定了主键，并且没有特别指定其他行为时，系统会自动启用对主键的验证和依赖关系。
+
+在这种默认行为下，无论是实时写入操作还是通过 SQL 进行的数据写入，系统都会依据所定义的主键进行去重处理。如果尝试插入与现有主键值重复的记录，系统将拒绝执行该插入操作，以确保主键的唯一性。例如：
+
+```sql
+create table test_primary(id int primary key,name string);
+desc extended test_primary;
+-- 此时插入成功，因为主键值 1 和 2 均未重复
+insert into test_primary values(1,"1");
+insert into test_primary values(2,"1");
+-- 插入失败，因为主键值 1 已存在
+insert into test_primary values(1,"1");
+select * from test_primary;
+```
+
+从上述示例可以看出，在默认的 `ENABLE VALIDATE RELY` 模式下，系统严格维护主键的唯一性，无论是单条记录插入还是批量插入，都会进行主键冲突检查。
+
+## 自定义主键行为
+
+如果您根据实际业务需求，希望在插入数据时仅由实时写入机制进行主键去重，而通过 SQL 写入时则不执行去重操作，可以通过将主键行为设置为 `DISABLE NOVALIDATE RELY` 来实现。以下是具体的操作示例：
+
+```sql
+create table test_primary_di(id int primary key DISABLE NOVALIDATE RELY ,name string);
+insert into test_primary_di values(1,"1");
+insert into test_primary_di values(2,"1");
+
+insert into test_primary_di values(1,"1");
+-- 插入成功，因为在 DISABLE NOVALIDATE RELY 模式下，SQL 写入不进行主键去重
+```
+
+需要注意的是，在 `DISABLE NOVALIDATE RELY` 模式下，虽然实时写入仍会依据主键进行去重，但通过 SQL 进行的写入操作将不会受到主键唯一性约束的限制，这可能导致数据中出现主键重复的情况。因此，在选择此种模式时，您需要对数据的写入来源和写入方式进行考虑和管理，以避免潜在的数据质量问题。
+
+# 主键表创建语法
+
+* 不带分区或分桶的主键表
+
+```
+CREATE TABLE pk_table
+(
+    id int,
+    col string,
+PRIMARY KEY (id)
+);
+CREATE TABLE pk_table
+(
+    id int PRIMARY KEY,
+    col string
+);
+```
+
+* 带分桶的主键表。
+  1. **未指定 DISABLE NOVALIDATE RELY 时**：
+
+     * Cluster Key 必须包含主键列
+     * 排序键必须包含主键
+  2. **指定 DISABLE NOVALIDATE RELY 时**：
+
+     * Cluster Key 可不包含主键列
+     * 排序键可不包含主键
+
+```
+--指定DISABLE NOVALIDATE RELY
+CREATE TABLE pk_table
+(
+    id int,
+    col string,
+    cluster_key string,
+    PRIMARY key (id) DISABLE NOVALIDATE RELY
+) 
+CLUSTERED BY ( cluster_key)  INTO 16 BUCKETS;
+--不指定DISABLE NOVALIDATE RELY
+CREATE TABLE pk_table
+(
+    id int,
+    col string,
+    cluster_key string,
+    PRIMARY key (id)
+) 
+CLUSTERED BY (id, cluster_key) SORTED BY (id) INTO 16 BUCKETS;
+
+
+```
+
+* 带主键的分区表。
+  1. **未指定 DISABLE NOVALIDATE RELY 时**：
+     * Partition Key 必须包含主键列
+  2. **指定 DISABLE NOVALIDATE RELY 时**：
+     * Partition Key 可不包含主键列
+
+```
+--指定DISABLE NOVALIDATE RELY
+CREATE TABLE pk_table
+(
+    id int,
+    col string,
+    pt string,
+    PRIMARY key (id)DISABLE NOVALIDATE RELY
+) PARTITIONED BY (pt);
+--不指定DISABLE NOVALIDATE RELY
+CREATE TABLE pk_table
+(
+    id int,
+    col string,
+    pt string,
+    PRIMARY key (id, pt)
+) PARTITIONED BY (pt);
+```
+
+# 使用注意事项
+
+**类型选择建议**
+
+* 优先使用数值类型（如 int/bigint 等）
+* 避免使用变长类型（如 string/varchar），以减少索引空间占用
+* 禁止使用浮点数类型（float/double）
+* 禁止使用嵌套类型
+  **约束条件**
+* 主键列必须定义为 NOT NULL
+* 不支持 Schema Evolution（表结构变更后主键不可修改）
+
+# 使用案例
+
+## 创建表
+
+在创建Lakehouse表时，需要指定主键。CDC写入会根据主键进行数据去重，以确保数据的准确性。创建的主键表不支持SQL操作，只能通过实时写入流进行数据写入。创建的主键表不支持也不支持使用SQL添加列和修改列。以下是一个创建表的示例：
+
+```sql
+CREATE TABLE igs_test_upsert (
+    id int PRIMARY KEY,
+    event varchar(100),
+    event_time STRING
+);
+```
+
+## SDK实时写入流
+
+### 创建实时写入流
+
+使用SDK创建实时写入流，需要指定操作类型（CDC）和相关选项。以下是一个创建实时写入流的示例：
+
+```java
+RowStream stream = client.newRealtimeStreamBuilder()
+    .operate(RowStream.RealtimeOperate.CDC)
+    .options(options)
+    .schema(schema)
+    .table(table)
+    .build(); // 关闭流，释放流资源，必须调用
+stream.close();
+```
+
+### 指定操作类型
+
+根据需求，可以指定不同的操作类型：
+
+* `Stream.Operator.UPSERT`：插入或更新行。如果目标行不存在，则插入；如果已存在，则更新。
+* `Stream.Operator.DELETE_IGNORE`：删除行。如果目标行不存在，则自动忽略。
+
+### 使用原生Java Sdk写入
+
+```java
+Row row = stream.createRow(Stream.Operator.UPSERT); // 插入或更新行
+Row rowToDelete = stream.createRow(Stream.Operator.DELETE_IGNORE); // 删除行
+```
+
+## 使用Lakehouse实时同步功能写入
+
+参考文档[多表实时同步](<multitable_realtime_sync.md>)
+
+## 使用FLINK CONNECTOR写入
+
+Flink connector是基于RealtimeStream SDK封装的，用于实现实时数据同步。查看[Flink Connector](<flink-write-connector.md>)

+# 私网连接（Private Link）概述
+
+> 【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请联系我们的技术支持人员协助处理。
+
+## 什么是私网连接 Private Link？
+
+**私网连接**（**Private Link**）（如 AWS PrivateLink、阿里云私网连接、腾讯云私有连接等）是云厂商提供的一种安全、私有的网络连接方式，可以让不同 VPC（Virtual Private Cloud）之间通过内网互联，而无需暴露在公网环境下，极大降低数据传输的安全风险。
+
+在 **Lakehouse** 平台中，Private Link 的应用场景主要有两大类：
+
+**1. 用户 VPC → Lakehouse（Inbound）**
+在云厂商的同 region、同可用区内，从用户的 VPC 通过云厂商的 Private Link 服务访问 Lakehouse（JDBC 网关、IGS 等）服务。
+
+:-: ![](.topwrite/assets/未命名绘图.drawio.png)
+
+例如：
+
+某公司在云上构建了自己的业务系统（电商平台、结算系统等），这些系统部署在其私有 VPC 中，不允许对公网开放访问。这家公司将销售交易数据、库存数据统一存储在 Lakehouse。在制作数据可视化、实时分析和报表时，由于内部合规及安全要求，不能通过公网访问 Lakehouse 中的数据。
+
+此时需要使用 Lakehouse 的私网连接功能，建立从客户 VPC 访问 Lakehouse 的终端节点。该公司对 Lakehouse 的访问都在其私有 VPC 中进行，通过终端节点的域名进行访问。
+
+^
+
+**2. Lakehouse → 用户 VPC（Outbound）**
+当需要从 Lakehouse（位于云器 VPC）连接到用户自定义服务（如用户 VPC 内自建的 MySQL 数据库）时，同样通过 Private Link 进行私网访问。
+
+:-: ![](.topwrite/assets/private_link访问客户.png)
+
+例如：
+某金融领域公司选择在 Lakehouse 进行统一数据存储与分析，但其核心业务数据库存放在私有 VPC 内部，且有严格的安全策略，禁止对公网暴露数据库端口。Lakehouse 需要通过实时集成读取数据，用于后续分析、风控模型训练等。
+
+此时首先需要客户在私有 VPC 内建立终端节点服务，然后需要使用 Lakehouse 的私网连接功能建立从 Lakehouse 访问客户 VPC 的终端节点。之后在 Lakehouse 中 [建立数据源](config-datasource.md) 的操作都使用该终端节点的域名和端口进行配置。
+
+^
+
+## 准备工作与注意事项
+
+1. **网络互通与 DNS 配置**
+
+   * 如果需要通过自定义域名（CNAME）访问 Private Link Endpoint，需在企业内部 DNS 中将解析指向 VPC 内的私有 IP。
+
+2. **安全组与端口放行**
+
+   * 当使用 Lakehouse 访问客户 VPC 时，需要客户在其私有 VPC 内，对终端节点服务所关联的负载均衡器（LB）放行相关的内网 IP 和端口。
+
+3. **默认带宽限制**
+
+   * 对于 Lakehouse 提供的终端节点服务，默认带宽为 **5 Mbps**。
+   * 如有大数据量传输需求，请联系 Lakehouse 支持团队提升带宽上限。
+
+4. **终端节点数量与账号管控**
+
+   * 为防止滥用或无序创建，每个云厂商账户 ID 最多只能创建 **5 个**终端节点；超限时 Lakehouse 平台会发出告警。
+
+5. **计费方式**
+
+   * Private Link 流量费用由客户直接支付给云厂商，不经过 Lakehouse 二次计量。
+
+6. **Multi-Account 场景**
+
+   * 如果客户有多个云厂商账户，需要在 Lakehouse 中分别将其账户 ID 添加到白名单；
+   * 并对应创建多个 Private Link Endpoint 进行分别管理。
+
+7. **公网阻断（可选）**
+
+   * 如果希望在完成私网连接后，彻底阻断从公网访问 Lakehouse，可在 Lakehouse 中启用 **网络访问策略**（或云厂商网络策略），仅允许来自指定 VPC 的 IP 范围进行连接。

+## ClickZetta Lakehouse Python SDK 实时写入
+
+## 安装
+
+1. 删除旧版本依赖
+
+如果安装过旧版本的sdk，先卸载旧版本的 clickzetta-connector-python 包 和 clickzetta-sqlalchemy 包
+
+```shell
+pip uninstall clickzetta-connector clickzetta-sqlalchemy clickzetta-ingestion-python clickzetta-ingestion-python-v2 -y
+```
+
+2. 安装 clickzetta-connector，Python版本要求 3.7 以上：
+
+```Bash
+pip install clickzetta-connector
+```
+
+## **实时写入原理**
+
+实时写入 Lakehouse 的Python SDK是一种高效的数据流处理工具，它允许用户将数据实时地上传并存储到Lakehouse中。以下是实时写入的工作原理：
+
+1. SDK上传数据 ：用户通过Python SDK将数据实时上传到Lakehouse的Ingestion Service。
+2. Ingestion Service处理 ：Ingestion Service接收到数据后，直接将数据写入到Lakehouse的表中，此时数据以临时中间文件的形式存储，这个阶段称为 混合表 。
+3. 查询实时数据 ：在数据提交之前，用户即可查询（select）到这些实时写入的新数据，但这些数据对于table stream、materialized view和dynamic table来说是不可见的。
+4. 数据提交 ：新写入的数据会在大约一分钟后自动提交，提交后，table stream、materialized view和dynamic table都能够读取这部分数据。
+5. 混合表变成普通表 ：在数据提交后，后台进程会将混合表合并变成普通表，合并完成后用户可以执行更新操作（update\merge\delete）。
+
+## **适用场景**
+
+实时写入 Lakehouse 的 Python SDK 适用于以下场景：
+
+* 短间隔数据导入 ：如果您的应用场景要求在非常短的时间间隔内（如5分钟或更短）导入数据，实时写入SDK可以满足您的需求。
+* 频繁小量数据提交 ：对于需要频繁提交数据，但每次提交的数据量不大的情况，实时写入SDK提供了一个高效的解决方案。
+* 实时数据分析 ：实时写入SDK适合需要对数据进行即时分析和响应的应用，例如实时监控、事件追踪和实时报告等。
+
+## **注意事项**
+
+* 实时写入的数据可以秒级查询。
+* 实时写入数据目前只能通过内部提供的 Flink Connector 中支持 schema change 的 sink 算子（单并发）来实现实时的表结构变化感知。在其他场景下进行表结构更改时，需要先停止实时写入任务，然后在表结构变更后一段时间（大约90分钟）后，重新启动任务。
+* table stream、materialized view 和 dynamic table 只能显示已经提交的数据。实时任务写入的数据需要等待 1 分钟才能确认，因此 table stream 也需要等待 1 分钟才能看到。
+
+## **数据类型支持**
+
+Lakehouse Python SDK支持以下数据类型映射：
+
+| SQL数据类型               | Python内部数据结构                   |
+| --------------------- | ------------------------------ |
+| BOOLEAN               | bool                           |
+| STRING / JSON         | str                            |
+| CHAR(n) / VARCHAR(n)  | str(超限写入将截断)                   |
+| BINARY                | bytes                          |
+| DECIMAL               | Decimal                        |

+
+## **通过客户端创建实时数据流**
+
+要创建实时数据流，首先需要使用 Lakehouse 客户端连接：
+
+```Python
+from clickzetta.connector.v0.connection import connect
+from clickzetta.connector.v0.enums import RealtimeOperation
+from clickzetta_ingestion.realtime.realtime_options import RealtimeOptionsBuilder, FlushMode
+from clickzetta_ingestion.realtime.arrow_stream import RowOperator
+
+
+# 创建连接
+with connect(username='your_username',
+             password='your_password',
+             service='your_service_endpoint',
+             instance='your_instance',
+             workspace='your_workspace',
+             schema='your_schema',
+             vcluster='your_vcluster') as conn:
+    
+    # 创建实时数据流
+    stream = conn.get_realtime_stream(
+        schema="your_schema",
+        table="your_table",
+        operate=RealtimeOperation.APPEND_ONLY,  # 普通表使用APPEND_ONLY
+        options=RealtimeOptionsBuilder().with_flush_mode(FlushMode.AUTO_FLUSH_BACKGROUND).build()
+    )
+    
+    # 使用完毕后关闭流
+    stream.close()
+```
+
+参数说明：
+
+* operate : 传入一个枚举值，实时接口支持 RealtimeOperation.APPEND\_ONLY 和 RealtimeOperation.CDC
+
+  * 普通表使用 RealtimeOperation.APPEND\_ONLY
+  * 主键表必须使用 RealtimeOperation.CDC
+
+* options : 用于传入实时写入流的参数，详见下文的选项说明
+
+## **选项（Options**）
+
+在Python SDK中，可以通过`RealtimeOptionsBuilder`类来配置实时写入流的参数。这些参数均为选填，推荐使用默认参数。
+
+```Python
+from clickzetta.ingestion.realtime.realtime_options import RealtimeOptionsBuilder, FlushMode, RetryStatus
+
+options = RealtimeOptionsBuilder()\
+        .with_flush_mode(FlushMode.AUTO_FLUSH_BACKGROUND) \
+        .with_mutation_buffer_lines_num(50000) \
+        .with_mutation_buffer_max_num(50) \
+        .with_mutation_buffer_space(20 * 1024 * 1024) \
+        .with_flush_interval(10 * 1000) \
+        .with_request_failed_retry_enable(True) \
+        .with_request_failed_retry_times(5) \
+        .with_request_failed_retry_internal_ms(5 * 1000) \
+        .with_request_failed_retry_log_debug_enable(True) \
+        .with_request_failed_retry_status([
+        RetryStatus.THROTTLED,
+        RetryStatus.INTERNAL_ERROR,
+        RetryStatus.FAILED,
+        RetryStatus.PRECHECK_FAILED]) \
+        .build()
+```

+
+## 写入数据（Row）
+
+通过`stream.create_row`方法创建具体的数据对象（Row），并通过`row.set_value`方法将数据封装到Row对象中。
+
+```Python
+# 创建一行数据
+row = stream.create_row(RowOperator.INSERT)  # 普通表使用INSERT
+
+# 设置字段值
+row.set_value("id", 1)
+row.set_value("name", "test_name")
+
+# 应用行数据到流中
+stream.apply(row)
+```
+
+**Row类型说明**：
+
+* 当Stream创建为`RealtimeOperation.APPEND_ONLY`时，仅能创建`RowOperator.INSERT`类型的Row。
+* 当Stream创建为`RealtimeOperation.CDC`时，可以使用以下Row类型：
+  * `RowOperator.UPSERT`：插入行，如果目标行已存在则更新该行。
+  * `RowOperator.DELETE_IGNORE`：删除行，如果目标行不存在则自动忽略。
+
+**注意**：主键表(PK表)必须使用CDC模式，且只能使用UPSERT和DELETE\_IGNORE操作类型。
+
+## 数据提交到服务端
+
+通过调用`stream.flush()`方法，数据会立即提交到服务端。如果没有显式调用此方法，数据会根据以下条件之一被自动提交：
+
+1. 达到`with_mutation_buffer_space`设置的缓冲区大小
+2. 达到`with_mutation_buffer_lines_num`设置的行数
+3. 达到`with_flush_interval`设置的时间间隔
+
+## 具体案例
+
+### 主键表（PK表）写入完整示例
+
+```Python
+from clickzetta.connector.v0.connection import connect
+from clickzetta.connector.v0.enums import RealtimeOperation
+from clickzetta_ingestion.realtime.arrow_stream import RowOperator
+from clickzetta_ingestion.realtime.realtime_options import RealtimeOptionsBuilder, FlushMode
+
+with connect(username='your_username',
+             password='your_password',
+             service='your_service_endpoint',
+             instance='your_instance',
+             workspace='your_workspace',
+             schema='your_schema',
+             vcluster='default') as conn:
+    
+    # 创建主键表
+    cursor = conn.cursor()
+    cursor.execute("""
+    CREATE TABLE test_pk (
+        id STRING NOT NULL PRIMARY KEY,
+        name STRING,
+        age INT
+    )
+    """)
+    
+    # 创建实时数据流 - 主键表必须使用CDC
+    stream = conn.get_realtime_stream(
+        schema=conn.get_schema(),
+        table="test_pk",
+        operate=RealtimeOperation.CDC,
+        options=RealtimeOptionsBuilder().with_flush_mode(FlushMode.AUTO_FLUSH_SYNC).build()
+    )
+    
+    # 写入数据 - 主键表使用UPSERT
+    for i in range(10):
+        row = stream.create_row(RowOperator.UPSERT)
+        row.set_value('id', f"id_{i}")
+        row.set_value('name', f"user_{i}")
+        row.set_value('age', 20 + i)
+        stream.apply(row)
+    
+    # 更新数据 - 主键表使用UPSERT
+    for i in range(5):
+        row = stream.create_row(RowOperator.UPSERT)
+        row.set_value('id', f"id_{i}")
+        row.set_value('name', f"updated_user_{i}")
+        row.set_value('age', 30 + i)
+        stream.apply(row)
+    
+    # 删除数据 - 主键表使用DELETE_IGNORE
+    for i in range(2):
+        row = stream.create_row(RowOperator.DELETE_IGNORE)
+        row.set_value('id', f"id_{i}")
+        stream.apply(row)
+    
+    # 关闭流
+    stream.close()
+    
+    # 验证结果
+    cursor.execute("SELECT COUNT(*) FROM test_pk")
+    count = cursor.fetchone()[0]
+    print(f"剩余记录数: {count}")  # 应该是8条记录(10-2)
+```
+
+## 常见问题与解决方案
+
+### 1. 主键表写入失败
+
+**问题**: 向主键表写入数据时出现错误。
+
+**解决方案**:
+
+* 确保使用了正确的操作类型：主键表必须使用`RealtimeOperation.CDC`模式，且只能使用`RowOperator.UPSERT`和`RowOperator.DELETE_IGNORE`操作。
+* 确保主键字段已正确设置值。
+* 主键表不支持`FlushMode.AUTO_FLUSH_BACKGROUND`，会自动重置为`FlushMode.AUTO_FLUSH_SYNC`。
+* 分区列要求是primary key的子集。
+
+### **2. 内存占用过高**
+
+**问题**: 写入大量数据时内存占用过高。
+
+**解决方案**:
+
+* 减小`with_mutation_buffer_lines_num`和`with_mutation_buffer_space`参数值。
+* 定期调用`stream.flush()`手动刷新数据，并尽量避免 flush 过于频繁，会导致大量小文件产生。
+* 考虑分批写入数据而不是一次性写入大量数据。
+
+## 总结
+
+ClickZetta Python SDK的实时写入功能提供了高效、灵活的数据写入方式，支持各种数据类型和操作模式。通过合理配置参数，可以根据不同场景优化写入性能。
+
+对于主键表和普通表，需要使用不同的操作模式和行操作类型。主键表必须使用CDC模式，且只能使用UPSERT和DELETE\_IGNORE操作；普通表通常使用APPEND\_ONLY模式和INSERT操作。

+# Python任务安装分发包与导入使用指南
+
+本文用于指导在 Python 任务中，从官方源或清华源安装分发包，并在后续代码中稳定导入使用。
+
+## 适用场景
+
+* 需要在任务运行时临时安装第三方包。
+* 需要从公网官方源（PyPI）或国内镜像（清华源等）安装包。
+* 需要将包安装到自定义目录（如 `/home/system_normal`）后再 `import`。
+
+## 运行时安装说明
+
+* Python 任务运行在临时 Pod 中，任务结束后环境会销毁。所以每次运行都需要重新安装该依赖，不要依赖“上一次安装结果”。
+* 必须使用 `--target` 安装，且必须把该目录加入 `sys.path` 后再导入。因为当前python运行时环境无 Root 权限，无法安装到全局 site-packages 目录，只能安装到用户目录下（如 `/home/system_normal`）。
+* 清华源（网络受限时可选）：`https://pypi.tuna.tsinghua.edu.cn/simple`
+
+## 标准模板（推荐直接复用）
+
+```python
+import subprocess
+import sys
+
+TARGET_DIR = "/home/system_normal"
+subprocess.check_call([
+    sys.executable, "-m", "pip", "install",
+    "config",
+    "--target", TARGET_DIR,
+    "-i", "https://pypi.tuna.tsinghua.edu.cn/simple"
+])
+sys.path.append(TARGET_DIR)
+
+from config import *
+```
+
+
+## 快速切换到清华源
+
+仅需把模板中的 `INDEX_URL` 改为：
+
+```python
+INDEX_URL = "https://pypi.tuna.tsinghua.edu.cn/simple"
+```
+
+## 常见错误与排查
+
+### 报错：`ModuleNotFoundError: No module named 'xxx'`
+
+按顺序检查：
+
+* 是否使用了 `--target`，但没有把该目录加入 `sys.path`。
+* 是否在 `import` 之后才追加路径（顺序错误）。
+* 是否把路径用 `append` 加到了末尾，导致被其他路径遮蔽。
+* 包名与模块名是否一致（有些包 `pip install A`，但 `import B`）。

+
+### 简单查询案例
+
+```python
+#创建游标对象
+cursor = conn.cursor()
+#执行 SQL 查询
+cursor.execute('SELECT * FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live LIMIT 10;')
+#获取查询结果
+results = cursor.fetchall()
+for row in results:
+print(row)
+```
+
+### 使用 SQL hints
+
+在 JDBC 中通过 set 命令设置的 SQL hints 可以通过 `parameters` 参数传递，支持的参数请参考 [参数管理](../sql-parmaters.md)。以下是一个示例：
+
+```python
+#设置作业运行超时时间为 30 秒
+my_param = {
+    'hints': {
+        'sdk.job.timeout': 30
+    }
+}
+cursor.execute('YOUR_SQL_QUERY', parameters=my_param)
+```
+
+### 使用
+
+## 更多示例
+
+### 1. 处理查询结果
+
+以下示例展示了如何处理查询结果，例如将结果保存到 CSV 文件中：
+
+```python
+import csv
+
+# 执行查询
+cursor.execute('SELECT * FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live LIMIT 10;')
+
+# 获取查询结果
+results = cursor.fetchall()
+
+# 将结果保存到 CSV 文件
+with open('output.csv', 'w', newline='', encoding='utf-8') as csvfile:
+    csv_writer = csv.writer(csvfile)
+    csv_writer.writerow([column[0] for column in cursor.description])
+    csv_writer.writerows(results)
+# 关闭连接
+cursor.close()
+conn.close()
+```
+
+### 高级功能
+
+> 注意：以下高级功能需要使用 `clickzetta-connector-python >= 0.8.82` 版本，或者 clickzetta-connector 版本 >= 1.0.11。
+
+#### 参数绑定
+
+clickzetta-connector 支持两种参数绑定风格，遵循 [PEP-249](https://peps.python.org/pep-0249/#paramstyle) 规范：
+
+| paramstyle | 描述                             | 示例                                    |
+| ---------- | ------------------------------ | ------------------------------------- |
+| qmark      | 使用问号 (?) 作为参数占位符                | `INSERT INTO test VALUES (?)`         |
+| pyformat   | 使用 Python 扩展格式代码，例如 `%(name)s` | `INSERT INTO test VALUES (%(value)s)` |
+
+##### 使用问号风格 (qmark)
+
+```python
+# 简单示例
+cursor.execute('INSERT INTO test (id, name) VALUES (?, ?)', binding_params=[1, 'test'])
+
+# JSON 类型示例
+json_data = "JSON '" + '{"id": 2, "value": "100", "comment": "JSON Sample data"}' + "'"
+my_param = {
+    'hints': {
+        'sdk.job.timeout': 30
+    }
+}
+cursor.execute('INSERT INTO test (id, json_col) VALUES (?, ?)', my_param, binding_params=[1, json_data])
+```
+
+##### 使用 qmark 风格批量插入
+
+使用 `executemany()` 方法支持高效地使用 qmark 风格执行批量插入操作：
+
+```python
+# 准备数据
+data = [
+    (1, 'test1'),
+    (2, 'test2'),
+    (3, 'test3')
+]
+
+# 执行批量插入
+cursor.executemany('INSERT INTO test (id, name) VALUES (?, ?)', data)
+```
+
+如需对输入的数据根据表结构进行自动转换，请开启 `tolerant` 参数并指定类型：
+
+```python
+# 准备数据
+data = [
+    (1, 'test1'),
+    (2, 0),
+    (3, 0.1)

+# Python/Shell 任务中使用数据源
+
+## 功能概述
+
+Python/Shell 任务，支持使用预先配置好的[数据源](config-datasource.md)。通过在运行环境里内置的 `clickzetta-dbutils` 工具包，在任务中可直复用`管理->数据源`中的连接配置信息，无需在节点中通过代码来重复设定，可提高敏感信息的安全性，也带来了开发和管理的便捷。
+
+^
+
+当前支持的数据源包括：
+
+* Lakehouse数据源
+* MySQL数据源
+* PostgreSQL数据源
+
+##
+
+## 界面操作指南
+
+### 在Python/Shell任务中选择数据源
+
+在Python/Shell任务的配置面板中，可以选择使用一个或多个数据源（确保数据源已经在管理->数据源里新建并测试连通通过）。该配置会作用于当前任务的直接运行或调度运行：
+
+![](.topwrite/assets/image_1742284598370.png =560)
+
+*注：当前工作空间的默认 Lakehouse 数据源，在此处不需添加即可在代码里直接访问*。
+
+###
+
+### 在代码中访问数据源
+
+添加完数据源后，即可开始编写 Python/Shell 任务代码，我们需要调用 `clickzetta_dbutils` python库中提供的 `get_active_engine("your_datasource_name")` 函数，仅需填写数据源名称，无需指定数据源URL、密码等连接信息即可完成数据源的连接。另外，还支持使用 `Builder` 模式，详见下文的 API 使用指南和代码示例。

+    .use_options({"charset": "utf8"})\
+    .build()
+
+# Lakehouse连接示例
+engine = DatabaseConnectionManager("LAKEHOUSE_source_name")\

+    .use_workspace("test-workspace")\
+    .use_schema("public")\
+    .build()
+```
+
+> 备注：其中 “LAKEHOUSE\_source\_name” 是指数据源管理中Lakehouse数据源的名称。
+
+## 代码示例
+
+### Python节点中使用PostgreSQL数据源示例
+
+示例为获取 postgres\_source\_name 数据源的所有 pg tables:
+
+```py
+from sqlalchemy import text
+from clickzetta_dbutils import get_active_engine
+
+# 使用默认schema
+engine = get_active_engine("postgres_source_name")
+with engine.connect() as conn:
+    results = conn.execute(text("SELECT * FROM pg_tables WHERE schemaname = 'public';"))
+    for row in results:
+        print(row)
+
+# 指定database和options中指定schema
+engine = get_active_engine("postgres_source_name", 
+                          schema="pg_database", 
+                          options={"search_path":"pg_schema"})
+```
+
+###
+
+### Python节点中使用MySQL数据源示例
+
+```py
+from sqlalchemy import text
+from clickzetta_dbutils import DatabaseConnectionManager
+
+# 查看所有可用的数据源配置
+print(DatabaseConnectionManager.load_connection_configs())
+
+# 创建连接并指定schema
+manager = DatabaseConnectionManager("mysql_source_name")
+manager.use_schema("test_schema")
+engine = manager.build()
+
+with engine.connect() as conn:
+    result = conn.execute(text("select * from test_table limit 1;"))
+```
+
+###
+
+### Python节点中使用Lakehouse数据源示例
+
+```py
+from sqlalchemy import text
+from clickzetta_dbutils import get_active_engine
+
+# 方式一：使用get_active_engine
+engine = get_active_engine("LAKEHOUSE_source_name", 
+                          vcluster="default", 
+                          workspace="test-workspace", 
+                          schema="public")
+
+# 方式二：使用get_active_lakehouse_engine
+from clickzetta_dbutils import get_active_lakehouse_engine
+engine = get_active_lakehouse_engine(vcluster="default", 
+                                   workspace="test-workspace")
+with engine.connect() as conn:
+    results = conn.execute(text("select 1"))
+    for row in results:
+        print(row)
+```
+
+###
+
+### Shell节点中使用数据源示例
+
+在Shell节点中，可以通过创建Python脚本文件的方式使用数据源：
+
+```bash
+cat >> /tmp/db_utils_demo.py << EOF
+from sqlalchemy import text
+from clickzetta_dbutils import get_active_engine
+
+engine = get_active_engine("postgres_source_name")
+with engine.connect() as conn:
+    results = conn.execute(text("SELECT * FROM test_table;"))
+    for row in results:
+        print(row)
+EOF
+
+python /tmp/db_utils_demo.py
+```
+
+##
+
+## 注意事项
+
+1. 数据源配置支持在Adhoc执行和调度执行两种场景下使用。
+2. 使用不存在的数据源名称会报错，请确保在使用前，Studio 中 `开发 -> python 任务 -> 数据源` 要选择相应的数据源。Postgres和MySQL数据源必须要在 `管理->数据源 `中新建并测试连通并确保通过。
+3. 使用Lakehouse数据源时必须配置vcluster参数。Lakehouse数据源直接使用在 `管理->数据源 `看到的内置Lakehouse数据源。
+4. 数据源的连接信息会被安全处理，可避免明文密码泄露。
+5. 支持在同一个节点中使用多个不同类型的数据源。

+本文旨在指导用户如何利用 SQL 语法高效地查询 JSON 类型的数据。通过掌握这些查询方法，用户能够简化查询流程。JSON 类型的创建请参考文档 [JSON类型](<JSON.md>)。
+
+## **语法**
+
+```SQL
+--键名访问JSON对象中的字段
+json_column['key']['key']...
+--通过索引访问JSON数组中的元素
+json_array[index]
+```
+
+**参数说明**
+
+* `json_column`：表示一个 JSON 字段，其类型为 JSON 对象。通过键名（`key`，指定为字符串）来定位并检索 JSON 对象内的特定数据字段。使用单个方括号 `[]` 可以访问对象的一级字段；而嵌套使用双方括号 `[][]` 则能够深入检索对象的二级或更深层次的字段。
+* `json_array`：表示数组类型的 JSON 字段，用于根据索引（index）访问 JSON 数组的元素，索引起始值为 0。
+
+**返回值说明**
+- 返回值为 JSON 类型。如需其他类型，可使用 CAST 函数进行强制转换。类型转换请参考 [JSON类型](<JSON.md>) 文档。

+# Lakehouse SQL查询语句
+
+## 功能简介
+
+Lakehouse支持使用标准的SQL SELECT语句进行数据查询。本文档将详细介绍查询语句的基本语法、参数说明以及使用示例，帮助您更高效地进行数据查询。
+
+## 基本语法
+
+```SQL
+[WITH cte [, ...] ]
+SELECT 
+[ hints ] 
+[ ALL | DISTINCT ]
+select_expr [, (except_expr)] ...
+FROM table_reference
+[WHERE where_condition ] 
+[GROUP BY [GROUPING SETS | ROLLUP | CUBE] {col_name | expr | position}]
+    [ HAVING having_condition ]
+[ ORDER BY order_condition [ ASC | DESC ] ]
+[ LIMIT  <number> [OFFSET <number>]]
+```
+
+## 参数说明
+
+**1. WITH cte** (可选)
+[公用表表达式](WITH.md)，用于在查询中定义临时结果集。
+
+**2. ALL | DISTINCT** (可选)：对结果集进行刷选，all 为全部，distinct 将刷选出重复列，默认为 all
+
+```
+--表示不对cp_start_date_sk去重
+SELECT ALL cp_start_date_sk FROM catalog_page;
+--表示对cp_start_date_sk去重
+SELECT DISTINCT cp_start_date_sk FROM catalog_page;
+```
+
+**3. HINTS** (可选): 帮助Lakehouse优化器作出更好的计划决策。目前支持[map join](mapjoin.md)如下案例
+
+```SQL
+SELECT /*+ MAPJOIN (t2) */ * FROM table1 t1
+JOIN table2 t2
+ON (t1.emp_id = t2.emp_id);
+```
+
+**4. select\_expr** (必填)
+指定需要查询的列，支持列名、列表达式等。例如：col1\_name, col2\_name, 列表达式, ...
+
+**1）排除列**（可选）
+可选。`except_expr`格式为`except(col1_name, col2_name, ...)`。当您希望读取表内大多数列的数据，同时要排除表中少数列的数据时，可以通过`SELECT * except(col1_name, col2_name, ...) from ...;`语句实现，表示读取表数据时会排除指定列（col1、col2）的数据。
+
+命令示例如下。
+
+```SQL
+--表结构如下
+DESC students;
++-------------+-----------+---------+
+| column_name | data_type | comment |
++-------------+-----------+---------+
+| name        | string    |         |
+| class       | string    |         |
++-------------+-----------+---------+
+--排除class列
+SELECT * EXCEPT(class) FROM students LIMIT 1;
++-------+
+| name  |
++-------+
+| Alice |
++-------+
+```
+
+**2）where\_condition** (可选)
+过滤条件，用于筛选满足指定条件的数据。支持关系运算符、like、rlike、in、not in、between…and等。
+
+* 配合关系运算符，筛选满足指定条件的数据。关系运算符包含：
+
+  * `>`、`<`、`=`、`>=`、`<=`、`<>`
+  * `like`、`rlike`
+  * `in`、`not in`
+  * `between…and`
+
+**5. GROUP BY expression**(可选)
+
+通常，group by和聚合函数配合使用，根据指定的普通列、分区列或正则表达式进行分组。`Grouping Sets`、`Rollup`、`Cube` 为 group by 的扩展，详细可以参考[GROUPING SET](groupby.md)，group by使用规则如下：
+
+* group by操作优先级高于select操作，因此group by的取值是select输入表的列名或由输入表的列构成的表达式。需要注意的是：
+
+  * group by取值为正则表达式时，必须使用列的完整表达式。
+  * select语句中没有使用聚合函数的列必须出现在group by中。
+
+**6. having\_condition**(可选)
+通常`having`子句与聚合函数一起使用，实现过滤。
+
+**7. order\_condition** (可选)
+对所有数据按照指定列或常量进行全局排序。默认为升序排序，可使用`desc`关键字进行降序排序。默认情况下，升序排序会将 `NULL` 值放在最前面，而降序排序则将 `NULL` 放在最后面。Order by 是比较耗时耗资源的操作，因为所有数据都需要发送到 1 个节点后才能排序，排序操作相比不排序操作需要更多的内存。
+
+**8. LIMIT ... OFFSET** (可选)
+
+* LIMIT \<number> 表示查询结果只返回前 \<number> 条记录，其中 \<number> 是一个正整数。这个语法可以用来分页或者限制查询的数据量。支持LIMIT m,n写法。**使用 limit  offset的时候要加上 order by 才有意义，否则每次执行的数据可能会不一致**
+* OFFSET \<number> 表示查询结果跳过前 \<number> 条记录，然后返回剩余的记录，其中 \<number> 是一个正整数。这个语法可以用来指定查询的起始位置。OFFSET关键字也可以用逗号代替
+* LIMIT 和 OFFSET 可以同时使用，也可以单独使用。如果同时使用，那么 OFFSET 必须在 LIMIT 之后。例如，LIMIT 10 OFFSET 20 表示查询结果跳过前 20 条记录，然后返回接下来的 10 条记录。
+
+## 查询历史版本数据
+
+除标准 `SELECT` 选项外，Lakehoue还支持用户在定义的时间段内的任何时间点访问历史数据，包括已更改或删除的数据。支持查询表、动态表和物化视图
+**请注意**：对象的历史查询取决于数据的保留周期。当前版本的数据保留周期默认为1天。您可以通过执行[ALTER命令](TIMETRAVEL.md)来调整保留周期。请注意，修改保留周期可能会增加存储成本。具体使用方式参考[TIME TRAVEL](TIMETRAVEL.md)
+
+```sql
+SELECT 
+    table_identifier TIMESTAMP AS OF timestamp_expression
+```
+
+通过使用TIMESTAMP AS OF子句，用户可以指定具体的时间点，查询保留期内表历史记录中指定点的精确位置或紧邻指定点之前的数据。Timestamp\_expression是一个返回时间戳类型表达式的参数，例如：
+
+* `'2023-11-07 14:49:18'`，即可强制转换为时间戳的字符串。
+* `CAST('2023-11-07 14:49:18' AS TIMESTAMP)`。
+* `CURRENT_TIMESTAMP() - INTERVAL 12 HOURS`。12小时之前的版本
+* 任何本身是时间戳类型或可强制转换为时间戳的表达式。
+  使用示例
+
+```
+SELECT * FROM events TIMESTAMP AS OF TIMESTAMP'2024-10-18 22:15:12.013'
+```
+
+## 语法糖：Trailing Commas
+
+在SQL语句中，使用Trailing Commas可以让语句更容易阅读和编辑。即使在最后一个值或参数后面多了一个逗号，也不会报错。例如：
+
+```SQL
+SELECT    client_ip,
+          client_identity,
+          userid,
+          user_agent,
+          log_time
+          -- status_code 
+FROM      server_logs;
+```
+
+## 注意事项
+
+* 建议您将提交的查询文本（即SQL语句）的大小限制为每个语句5MB。大于5MB的SQL文本将无法提交。如果您有超出5MB的SQL文本，请提交工单解决。
+  当然可以，以下是根据您提供的 Apache Doris `SELECT` 语句文档和 Lakehouse SQL查询语句文档，生成的使用示例和最佳实践：
+
+### 使用示例
+
+1. **基本查询**
+   ```SQL
+   -- 查询所有学生的姓名和班级
+   SELECT name, class FROM students;
+   ```
+
+2. **使用WITH子句（公用表表达式**）
+   ```SQL
+   WITH ranked_students AS (
+     SELECT name, class, RANK() OVER (ORDER BY score DESC) as rank
+     FROM students
+   )
+   SELECT * FROM ranked_students WHERE rank <= 10;
+   ```
+
+3. **去重查询**
+   ```SQL
+   -- 查询不同的班级名称
+   SELECT DISTINCT class FROM students;
+   ```
+
+4. **使用HINTS优化查询**
+   ```SQL
+   SELECT /*+ MAPJOIN(t2) */ * FROM students t1
+   JOIN classes t2 ON t1.class_id = t2.id;
+   ```
+
+5. **条件筛选**
+   ```SQL
+   -- 查询年龄大于20岁的学生姓名
+   SELECT name FROM students WHERE age > 20;
+   ```
+
+6. **GROUP BY 和聚合函数**
+   ```SQL
+   -- 按班级分组，查询每个班级的平均成绩
+   SELECT class, AVG(score) FROM students GROUP BY class;
+   ```
+
+7. **使用HAVING子句**
+   ```SQL
+   -- 查询平均成绩大于60分的班级
+   SELECT class, AVG(score) as avg_score FROM students GROUP BY class HAVING avg_score > 60;
+   ```
+
+8. **ORDER BY 和 LIMIT**
+   ```SQL
+   -- 查询成绩降序排列的前5名学生
+   SELECT name, score FROM students ORDER BY score DESC LIMIT 5;
+   ```
+
+9. **查询历史版本数据**
+   ```SQL
+   -- 查询2024-10-18 22:15:12.013时刻的学生表数据
+   SELECT * FROM students TIMESTAMP AS OF TIMESTAMP'2024-10-18 22:15:12.013';
+   ```
+
+10. join示例
+    参考[Join](JOIN.md)相关使用
+
+## 最佳实践
+
+1. **利用分区分桶过滤**
+   * 尽可能利用Lakehouse的分区分桶作为数据过滤条件，减少数据扫描范围。
+
+2. **使用索引字段**
+   * 充分利用Lakehouse的索引字段作为数据过滤条件加速查询速度。参考[索引](guid-index.md)。
+
+3. **合理使用聚合**
+   * 聚合操作应该在数据量较大时使用，以减少数据传输和提高查询效率。
+
+4. **使用ORDER BY和LIMIT进行分页**
+   * 当需要分页查询时，使用ORDER BY和LIMIT组合可以有效地获取特定页面的数据。
+
+5. **注意数据类型匹配**
+   * 在使用UNION或JOIN时，确保连接的列具有相同的数据类型。
+
+6. **避免大查询文本**
+   * 将查询文本大小限制在5MB以内，以避免提交失败。
+
+7. **使用HAVING子句过滤聚合结果**
+   * HAVING子句应该在聚合函数之后使用，以过滤聚合后的结果集。
+
+8. **使用WITH子句简化复杂查询**
+   * 公用表表达式（WITH子句）可以简化复杂的查询，使其更易于理解和维护。
+
+9. **注意查询成本**
+   * 修改数据保留周期可能会增加存储成本，合理设置数据保留周期以平衡查询需求和成本。

+# 入门指南：如何快速创建同步任务来导入数据
+
+## 适用场景
+
+如果您的数据存储在数据库、对象存储等系统上，需要导入到 Lakehouse 进行处理和分析，则适合阅读本文档。如果您需要导入存在本地文件中的数据，可以直接参考 [如何快速上传导入本地数据](quick_start_upload_data.md)，会更加便捷。
+
+## 前置阅读
+
+在阅读本指南之前，建议先阅读并理解以下文档：
+
+* [Lakehouse 产品简介](what_is_clickzetta_lakehouse.md)
+* [产品基本概念](Key_Concepts.md)
+* [Lakehouse Studio 快速导览](LakehouseStudioTour.md)
+* [数据同步功能概述](data-integration-intro.md)
+* [数据源管理与配置指南](config-datasource.md)
+
+## 操作指南
+
+您可以通过 Lakehouse Studio 提供的「同步任务」功能，将数据库、对象存储等系统上的数据同步导入到 Lakehouse 中。本文以MySQL作为源端为例进行介绍。
+
+### 使用说明
+
+* 同步任务采用从源端拉取数据的方式，依赖源端数据源网络可达性。建议使用具备公网访问能力的数据源进行功能体验。在复杂网络情况下，例如需要同步 VPC 内的数据库数据，需要进行网络打通，可参考 [利用 PrivateLink 通过 VPC 网络同步 RDS 数据(阿里云)](StudioDI_PrivateLinkVPC_fromRDS.md) 文档详细了解。
+* 需要具备 `工作空间管理员角色（workspace_admin）` 或 `工作空间开发角色(workspace_dev)` 权限的用户，才能使用「同步任务」功能。
+
+### 操作步骤
+
+1. 如下图所示，点击按钮进入 Lakehouse 服务实例：
+
+   ![](.topwrite/assets/image_1748337538227.png)
+
+2. 导航到「开发」页面：
+
+   ![](.topwrite/assets/image_1748337566571.png)
+
+3. 在左侧目录树的文件夹区域，点击 + （新建）按钮，在菜单中选择「离线同步」任务类型：
+
+   ![](.topwrite/assets/image_1748337579720.png)
+
+4. 在弹框中，输入任务名称（可创建一个文件夹，非必须），点击“确定”。
+
+   ![](.topwrite/assets/image_1748337590537.png)
+
+5. 在页面上即可看到新建的同步任务，如下图所示：
+
+   ![](.topwrite/assets/image_1748337598616.png)
+
+6. 开始配置同步任务的必填信息，核心是配置来源和目标端的信息。
+   备注：此处需要理解“数据源”概念。“数据源”是定义外部服务连接信息的对象，包括服务地址、认证信息、连接方式等。定义好的数据源可以在数据同步任务中作为数据来源或数据目标使用。
+
+7. 源端配置如下图所示，点击“+”后可以快速唤起新建数据源的界面：
+
+   ![](.topwrite/assets/image_1748337608071.png)
+
+8. 选择需要导入的数据源类型，本示意中选择 MySQL，点击“下一步”进入详情配置页面。右上角的“使用说明”中，配套了详细的配置指南，如下图所示。请确保填写的 JDBC 连接地址、用户名和密码正确。serverTimezone 配置项是指数据库所在的时区，会影响同步到目标端后日期和时间字段的取值，请根据实际情况正确选择。
+
+   ![](.topwrite/assets/image_1748337616322.png)
+
+9. 完成数据源的必填信息配置后，可以点击“连通性测试”按钮来测试数据源是否可以连通访问。测试连通正常如下图所示。如果不能连通，请检查网络和配置信息是否准确。测试通过后，点击右下角的确定进行保存。
+
+   ![](.topwrite/assets/image_1748337623157.png)
+
+10. 完成数据源创建后，回到同步任务配置页面，选择该数据源作为源端（如果没有自动展示，请重新打开任务），并选择命名空间（即数据库）和数据对象（即表），其他配置项可留空。
+
+    ![](.topwrite/assets/image_1748337630413.png)
+
+11. 完成源端配置后，进行目标端的配置，如下图所示：
+
+    ![](.topwrite/assets/image_1748337636870.png)
+
+    1\). 选择Lakehouse数据源类型
+
+    2\). 选择内置的 quick_start 工作空间（可类比理解为 database）。
+
+    3\). 选择 public 命名空间（即：schema）
+
+    4\). 数据对象，可以通过 + 按钮，快速新建目标Lakehouse表，在弹框中核对表的命名和schema信息后，点击“确定”按钮，完成表的创建。
+
+    ![](.topwrite/assets/image_1748337664468.png)
+
+    5\). 数据写入模式选择“覆盖写入”，即在同步前会先清空目标表中的数据，再写入从源端获取的数据。
+
+12. 完成上述步骤后，在“字段映射配置”中会自动展示源端表和目标表的字段映射关系（默认是同名映射）。此处使用默认方式即可，无需修改。
+
+    ![](.topwrite/assets/image_1748337679341.png)
+
+13. 其他配置项，例如同步规则配置、高级配置等，使用默认值即可。
+
+    ![](.topwrite/assets/image_1748337686553.png)
+
+14. 点击任务配置区域上方的“保存”按钮，保存任务的全部配置。
+
+    ![](.topwrite/assets/image_1748337694348.png)
+
+15. 点击右上角的“运行”按钮，运行测试并触发数据同步（集群选项使用默认值即可）。
+
+    ![](.topwrite/assets/image_1748337705970.png)
+
+16. 在页面右下角的“运行历史”区域，可以查看到任务的运行情况。
+
+    注：如果想测试同步速度，建议使用数据量相对较大的表进行测试，以降低任务启动时间带来的影响。
+
+    ![](.topwrite/assets/image_1748337713243.png)
+
+17. 至此，就完成了一个同步任务的创建和运行，将 MySQL 的数据导入到了 Lakehouse 中。接下来可以基于导入的数据做后续分析和处理加工。
+
+## 相关文档
+
+* 您可以阅读 [数据同步 | 文档目录](data-integration.md) 的文档来了解数据同步任务的完整使用指南。
+* 您可以阅读 [将数据导入Lakehouse的完整指南](a_comprehensive_guide_to_ingesting_data_into_clickzetta_lakehouse.md) 来全面了解将数据导入到Lakehouse中的各种方式。
+
+## 下一步建议
+
+* 完成数据上传之后，可以参考 [如何快速运行一个SQL](quick_start_sql_query.md) 的指南文档，对导入到表中的数据进行查询分析。

+
+这里的任务名称暂时命名为 “MYSQL数据集成任务”，点击确定。
+
+![](.topwrite/assets/image_1692605970219.png =658)
+
+在 ① 的列表处可见刚才创建的任务，点击 ② 处选择数据源类型为 ③ 处的 MYSQL，并选择到我们刚才创建的数据源名称：BizData\_Demo
+
+![](.topwrite/assets/image_1692606182111.png)
+
+在 ① 处选择库，在 ② 处选择表，在 ③ 处添加过滤条件，点击 ④ 处的按钮可以进行数据的预览。*splitPk 是用于多并发抽取数据用的切分键，需要根据数据库中表 INT 类型主键进行数据分割，非必要项，此处不做深入演示*。

+点击 \[预览] 按钮后，会根据配置的过滤条件预览少量数据。
+
+![](.topwrite/assets/image_1692608871867.png =668)
+
+由于我们是从 MySQL 数据源向云器 Lakehouse 进行数据同步，那么目标端数据源自然是选择 Lakehouse 类型，如下图 ① → ② → ③ 步骤所示
+
+![](.topwrite/assets/image_1692609388901.png)
+
+① 处的命名空间可以先选择默认的 public，数据对象由于是首次创建任务，还没有在 Lakehouse 端进行建表，所以 ② 处提供了贴心的一键建表功能。
+
+![](.topwrite/assets/image_1692610106739.png =490)
+
+在弹出的一键建表窗口，如果点击 \[确定] 按钮，会直接创建 Lakehouse 表；此外，还支持复制建表语句，方便用户进行修改后单独做创建操作。

+
+那么万一字段映射填写错乱了，想要重置字段映射关系该怎么办？在这里我们也贴心准备了重置刷新等功能，分别是 ① 同名映射 ② 重置刷新 ③ 清除映射 ④ 全屏化。

+^
+
+![](.topwrite/assets/image_1692868770187.png =637)
+
+^
+
+任务配置完成后，位于 ① 处的 \[保存] 可对任务进行保存，位于 ② 处的 \[版本] 可以查看历史版本信息，这里不再赘述。值得一提的是位于 ③ 处的 \[调度] 配置完成后，可以解锁后面的 \[提交] 按钮，只有任务提交到生产环境了，才会根据调度的配置进行作业的调度，因此在任务 \[提交] 后会解锁 \[运维] 按钮。
+
+^
+
+但在任务保存之后，我们通常会点击位于 ④ 处的 \[运行] 按钮，尝试手动运行任务，完成数据的初始化集成。
+
+^
+
+![](.topwrite/assets/image_1692869115260.png =807)
+
+点击 \[运行] 启动任务以后，① 处的 \[运行] 按钮会变成  \[停止] 按钮，下方的运行历史会增加一个条目，在 ② 处标记了正在运行的任务实例，右侧的操作栏下，一般查看位于 ③ 处的 \[日志] 即可查看任务运行详情。
+
+^
+
+![](.topwrite/assets/image_1692869694189.png)
+
+^
+
+日志信息如下所示：
+
+^
+
+![](.topwrite/assets/image_1692869803721.png)
+
+^
+
+接下来等待任务完成即可。至此，数据已经写入云器 Lakehouse 了。
+
+^
+
+![](.topwrite/assets/image_1692877068479.png =426)
+
+^
+
+#### 【配置调度依赖】
+
+我们先别急着去查看数据条数，继续完成调度上的配置。点击上边功能菜单的 \[调度] 按钮，右侧滑出调度菜单，我们下拉快进到 \[调度时间] 部分：在离线 T+1 场景中，调度周期配置为 \[每天调度] 、\[执行一次]、\[00:00 开始调度]、当天开始生效、\[永不失效] 即可。
+
+^
+
+其中 ① 处还可以选择为 \[每月指定天]，\[每周指定天] 的方式，② 处可以选择为 \[执行多次] X 分钟的调度周期间隔。
+
+^
+
+在 \[实例信息] 部分，由于我们刚刚已经运行过任务了，那么位于 ③ 处的实例生成方式可以选择为 \[次日生效]。（注意：每日多次的任务在发布后要选择 \[发布后生效]，否则要等到第二天才会开始运行）
+
+^
+
+\[实例遇错重跑]，则是处理任务报错重跑的策略，通常我们选择 \[运行成功或失败后皆可重跑] 即可，这里不作过多赘述。
+
+^
+
+![](.topwrite/assets/image_1692877280440.png =752)
+
+^
+
+最后我们来到 ① \[调度依赖] 和 ② \[任务产出] 这部分，配置完成后我们点击 ③ \[确定] 按钮，即可解锁 \[提交] 按钮了，就具备将任务提交到生产环境进行作业调度的条件了。
+
+^
+
+关于 \[调度依赖]，我们都知道一个标准的数仓处理过程都是从数据的接入开始的，所以数据集成任务通常作为整个链路的起始节点，是没有上游依赖任务的，因此位于 ① 处的 \[调度依赖] 此处不作任何设置。当然数据集成任务一般也不会长达一天的时间，因此下方的 \[自依赖] 也无需勾选。
+
+^
+
+![](.topwrite/assets/image_1692929739481.png =450)
+
+^
+
+关于 \[任务产出]，首先要解释一下任务产出是做什么用的：当前完成配置的数据集成任务的作用是把源端数据库对应表的数据写入目标端的目标表，因此在整个调度系统中，需要宣称这个目标表是被这个任务所“生产出来”的，即“任务产出”。
+
+^
+
+此处所定义了的任务产出的表名，不单单必须是目标表的“物理真名”，也可以是人为更改的其他“别名”，甚至是多个不同的别名。其最主要的作用是使该任务所产出的表可以在整个调度依赖系统中被其他任务搜索到，从而形成上下游的依赖关系。其最大的应用则是在调度系统中可以被其他任务所依赖。
+
+^
+
+因此，这里提供了人工自定义添加表名，和系统 \[智能解析] 功能按钮。本例中，不做别名的特殊调整，所以直接选择 \[智能解析] 即可，如图所示。
+
+^
+
+![](.topwrite/assets/image_1692930975096.png =513)
+
+^
+
+完成配置后点击 \[确定]，解锁 \[提交] 按钮。
+
+^
+
+![](.topwrite/assets/image_1692931241963.png =498)
+
+^
+
+#### 【提交发布任务】
+
+点击 \[提交] 按钮，会弹出与历史版本对比的确认窗口，本例中是首次提交，直接点击 \[确定] 即可。
+
+![](.topwrite/assets/image_1692931416038.png =564)
+
+^
+
+提交成功后会弹出提示，并且任务状态会改变：\[未提交] → \[已提交]
+
+![](.topwrite/assets/image_1692931479995.png =432)
+
+^
+
+至此，一个数据集成任务就发布完成了。
+接下来我们可能会有两个疑问：
+1、刚才同步了数据，我是不是要查看一下数据量对不对，并进行一下预览；
+2、数据集成任务发布到调度系统中去了，怎么去运维和查看这些任务。
+针对以上的 2 个问题，我们分别会在接下的【数据开发】章节与【任务实例运维】章节进行讲解。
+
+^
+
+#### 【创建数据开发任务】
+
+按图所示创建 SQL 任务，可以进入到 SQL 的 编辑器页面，我们先进行一些基本的数据探查，比如核对一下刚刚接入表的数据量，预览一些数据等等。
+
+![](.topwrite/assets/image_1692947107206.png =417)
+
+^
+
+任务名称暂定为 “SQL数据开发任务”，点击确定。
+
+![](.topwrite/assets/image_1692947166405.png =317)
+
+^
+
+创建成功后进入 SQL 编辑器，功能按钮与数据集成任务大致相同，多了 \[格式化] 按钮用于美化 SQL。
+
+![](.topwrite/assets/image_1692947217040.png =688)
+
+^
+
+通过统计表条目数语句，查询结果。在 ① 处可以局部 / 单行执行 Query，在 ② 处会全部脚本运行任务，无论用 ① 或 ② 的方式，运行都是在 ③ 处查看结果。
+
+![](.topwrite/assets/image_1692953836250.png =678)
+
+^
+
+之后我们再去源端数据库中查询一下这个表的条目数，可以发现两边条目数一致。（别忘了我们再数据集成的 \[筛选] 处添加了 event\_id is not null，在查询源端数据库时也要加上这个条件）
+
+![](.topwrite/assets/image_1692954920520.png =513)
+
+^
+
+好的，两边数据量一致，再通过类似以下的脚本来预览一下数据，看看数据格式是否都正确等等。
+
+```
+select * from tablename[你的表名] limit 10
+```
+
+^
+
+截止到这一步，基本的数据探查已经完成，接下来我们来构建整个工作流。
+
+^
+
+让我们再来确认一下业务目标：我们按照从左到右的顺序，已经完成了数据源的配置，并且学会了如何创建数据集成任务和数据开发任务。
+
+![](.topwrite/assets/image_1693020935459.png =610)
+
+^
+
+那么，我们只需要重复多次【创建数据集成任务】，就可以将这 4 张表创建出来，并将数据接入到云器 Lakehouse。
+
+^
+
+通过任务名称右侧的 \[更多] 选项中的 \[复制] 功能，可以快速复制出 4 个来自相同数据源的任务，再略微修改配置，一键创建目标表，可以非常方便地完成任务的创建。
+
+![](.topwrite/assets/image_1693016680123.png =329)
+
+^
+
+复制出来的任务名默认是在原有任务名上增加 “\_copy”，这里只需要按需改成我们想要的名字即可。
+
+![](.topwrite/assets/image_1693016822970.png =294)
+
+^
+
+接下来，修改数据开发任务中的脚本内容，完成 user\_log 表与 shop、goods、timezone 3个维度表的关联查询，并将结果写入 dwd\_user\_charac，如果是首次创建表，可以使用 create table xxx as select... 的语句，单独运行一次即可。当然如果需要每天进行任务调度的话，最终提交的任务中，写入方式应该是 \[覆盖写入]（insert overwrite）。
+
+![](.topwrite/assets/image_1693034692564.png =577)
+![](.topwrite/assets/image_1693034727649.png =547)
+
+^
+
+通过模糊检索选择上游的调度依赖。
+
+![](.topwrite/assets/image_1693186498403.png)
+
+^
+
+我们直到所有的数据集成任务都完成后才能执行 SQL 加工任务，因此添加四次上游任务即可。
+
+![](.topwrite/assets/image_1693188053947.png =354)
+
+^
+
+其他的配置与上面讲过的方法一样，最后别忘了 \[保存] 和 \[提交]，所有提交后的任务图标应该是带有绿色圆圈上角标的样式。
+
+![](.topwrite/assets/image_1693188429895.png =217)
+
+^
+
+好的，至此，我们已经完成了所有数据集成任务和数据开发任务的创建，并且已经运行过了一轮任务。接下来，我们介绍一下如何去 \[运维中心] 中查看这些任务实例及血缘关系。
+
+^
+
+#### 【任务运维】
+
+^
+
+任务提交到生产之后，我们来介绍一下基础的运维工作。通过左边菜单栏点击 ① 处的 \[任务运维] 进入到运维中心。按照上面 ②③④⑤ 的页签，分别表示了 \[周期任务]、\[实时任务]、\[补数任务]，以及 \[任务实例]。
+
+^
+
+当我们点击进入【任务运维】功能模块时，页面默认跳转到的是 ④ 的 \[任务实例]，因为运维人员一般关心的就是任务实例每天的运行状态和运行结果如何。而任务实例分为 ⑥ \[周期实例]、⑦ \[临时实例] 两种，任务实例的运行状态有：⑧ \[运行成功]、⑨ \[运行中]、⑩ \[运行失败] 3 种。
+
+^
+
+![](.topwrite/assets/image_1693193833131.png)
+
+^
+
+这里我们要理解【任务】和【实例】的区别：任务是指一种预设的工作流程配置，而实例则是将这些工作流程配置的实例化，也就是实际执行的事例。
+
+^
+
+我们点击周期任务这个页签，查看我们发布的 SQL 数据开发任务，可以进入到任务详情页面。
+
+![](.topwrite/assets/image_1693202818256.png)
+
+^
+
+任务详情页面除了自身的信息 ①\[任务详情] 以外，还提供 ② \[任务实例]、③ \[节点代码]、④ \[操作日志] 的查看页签，这里仅展示任务详情页签。
+任务详情上半部分展示的是任务的一些元数据信息。
+
+![](.topwrite/assets/image_1693203132344.png)
+
+^
+
+下半部分则展示的是该任务与上下游任务之间的依赖关系。
+
+![](.topwrite/assets/image_1693202961210.png)
+
+^
+
+那么上面是任务的详情，在实例的详情中一样可以看到实例的运行状态，和任务详情相似，不同的是节点展示的是实例的实际运行情况，并支持对实例进行一些置成功、置失败、重跑等操作，这里一样不加以赘述了。
+
+^
+
+#### 【连接 BI 工具】
+
+根据上面的内容，我们假设现在所有的数据准备工作已经完成，下一步就是数据的应用了，在本例中数据仓库加工后的数据最终展示在 BI 看板上。
+
+^
+
+首先我们要了解的一点是，云器 Lakehouse 提供了丰富的 SDK，允许 BI 工具通过 JDBC 或 Python SqlAlchemy 直接连接访问 Lakehouse，因此市面上常规的 BI 工具，如：帆软 BI、SuperSet、Tableau、衡石 BI、Power BI 等大多都可以支持。
+
+^
+
+以帆软 BI 为例，首先我们可以到 < [JAVA SDK 简介](java_reference/java-sdk-summary.md)>  章节处获取 JDBC Driver 。
+
+![](.topwrite/assets/image_1693290887172.png =251)
+
+^
+
+下载到 JAVA SDK 后，我们需要在帆软 BI 的系统设置中将这个 Driver 添加到第三方数据连接驱动中。
+帆软 BI 稍微特殊一些，默认是不允许用户本地上传驱动的，需要打开后台的开关。操作步骤参见官网文档：
+<https://help.fanruan.com/finebi/doc-view-1540.html>
+
+^
+
+在获准管理驱动之后，我们通过系统设置进入到数据连接管理。
+
+![](.topwrite/assets/image_1693207507345.png =752)
+
+^
+
+在右侧的页面中选择 \[驱动管理] → \[新建驱动]
+
+![](.topwrite/assets/image_1693207760197.png =247)
+
+^
+
+驱动名称可以自定义命名。
+
+![](.topwrite/assets/image_1693207884575.png =284)
+
+^
+
+按图上 ① 处上传文件，文件上传及解析后在 ② 处点选 ③ 的类。
+
+![](.topwrite/assets/image_1693208001316.png =687)
+
+^
+
+点击右上角进行驱动的保存。
+
+![](.topwrite/assets/image_1693208098173.png =625)
+
+^
+
+配置完成后，我们退回到数据连接管理，就可以新建 Lakehouse 的数据源了。
+
+![](.topwrite/assets/image_1693209222368.png =223)
+
+^
+
+由于我们目前还属于第三方连接驱动，因此我们选择 \[其他] → \[其他 JDBC]
+
+![](.topwrite/assets/image_1693209282780.png =516)
+
+^
+
+在这里，我们选择驱动类型中的 \[自定义]
+
+![](.topwrite/assets/image_1693209346360.png =415)
+
+^
+
+如果找得到我们刚才添加的驱动选项则直接选择，如果找不到则点击右侧的 \[添加驱动]
+
+![](.topwrite/assets/image_1693209431798.png =690)
+
+^
+
+我们仅需要定义一个 \[数据库名称]，以及填写 \[用户名]、\[密码]、 \[数据连接 URL] 等信息。不清楚 URL 如何填写的用户，可以查看帮助文档的 SDK 章节，或联系你们的客户经理。
+
+![](.topwrite/assets/image_1693209540889.png =385)
+
+^
+
+填写后点击 \[测试连接]，如果配置正确会显示【连接成功】，点击 \[保存] 按钮完成创建。
+
+![](.topwrite/assets/image_1693209771680.png =723)
+
+^
+
+如果连接名称显示受 URL 影响，也可以通过 \[重命名] 的方式进行自定义。
+
+![](.topwrite/assets/image_1693211182568.png =342)
+
+^
+
+数据连接创建成功后，BI 工具就可以像访问其他数据库一样访问 云器 Lakehouse 了。基于数据源创建数据集，添加数据库表，就可以访问 Lakehouse 中的表了。
+
+![](.topwrite/assets/image_1693211916144.png =297)
+
+^
+
+![](.topwrite/assets/image_1693212056036.png =651)
+
+创建仪表板引用数据集进行编排，感兴趣的同学可以参考帆软 BI 的帮助文档。
+<https://help.fanruan.com/finebi/>
+
+^
+
+通过一定的看板样式设计，我们可以做出丰富多彩的 BI 看板了。

+# 入门指南：如何快速新建和使用工作空间
+
+## 适用场景
+
+工作空间是用于组织 Lakehouse 资源对象（数据对象、计算资源、用户等），并提供配套的数据开发能力（数据集成、数据开发、数据运维）的逻辑对象。完成注册登录、开通Lakehouse产品后，在服务实例下会默认初始化出来一个名为 `quick_start`的工作空间。这个工作空间里也内置了一些样例数据和样例代码，您如果计划基于该工作空间来使用产品功能，可以跳过此文档，建议您参考以下文档来开始使用产品：
+
+* [如何快速运行一个SQL](quick_start_sql_query.md)
+* [如何快速上传导入数据](quick_start_upload_data.md)
+
+如果您想创建更多的工作空间来满足不同的使用场景的需要，比如按照业务来区分工作空间或者按照数仓规划的分层来组织工作空间，可阅读此文档。
+
+## 前置阅读

+# 入门指南：如何快速配置和使用数据质量规则
+
+## 适用场景
+
+数据质量规则用于校验数据对象的质量是否符合要求，比如数据的正确性、有效性和一致性等，尤其是对于服务于生产使用的任务产出的数据表。如果您配置了ETL流程，比如前文的 [入门指南：如何快速配置编排和周期调度ETL流程](quick_start_etl.md)，计划对数据的质量增加一个检查，建议阅读此指南。
+
+## 前置阅读
+
+在阅读本指南之前，建议完成以下文档的阅读和理解：
+
+* [Lakehouse 产品简介](what_is_clickzetta_lakehouse.md)
+* [产品基本概念](Key_Concepts.md)
+* [Lakehouse Studio 快速导览](LakehouseStudioTour.md)
+
+## 操作指南
+
+您可以通过 Lakehouse Studio 提供的「数据质量」功能来配置质量规则进行检查。检查主要基于数据质量规则来进行。规则会预先定义校验的对象、检查逻辑和预期结果，并可以通过多种方式触发运行。本示例展示如何为一张 Lakehouse 表的字段配置规则，以校验其取值非空。
+
+### 使用说明
+
+* 具备 `工作空间管理员角色（workspace_admin）` 或 `工作空间开发角色(workspace_dev)` 的用户，有权限使用「数据质量」功能。
+* 「数据质量」功能目前主要用于监控 Lakehouse 的数据对象，比如 Table、View、Volume、Dynamic Table 等，对于 MySQL 等其他数据类型，暂不支持。
+
+### 操作步骤
+
+1. 如下图所示，点击按钮进入 Lakehouse 服务实例：
+
+   ![](.topwrite/assets/image_1748337538227.png)
+
+2. 导航到「数据」>「数据质量」页面：
+
+   ![](.topwrite/assets/image_1749449999835.png)
+
+3. 在“质量规则”Tab页，点击“新建规则”按钮，打开新建质量规则的页面。请注意核对，确保页面右上角的工作空间是需要校验的数据表所在的工作空间。如果不是，可以点击后进行切换。
+   ![](.topwrite/assets/image_1749450019542.png)
+
+4. 在新建规则页面，工作空间的值会自动设定为上一步选择的工作空间【1】。选择需要校验的数据对象。本示例中，选择先前ETL流程中同步任务导入数据写入的 `test_json` 表进行校验【2】。质量规则执行时，实际上会转化为 Lakehouse SQL 语句执行，因此需要一个执行集群。为简单起见，建议直接选择默认的 GP 类型集群 `DEFAULT`【3】。
+   ![](.topwrite/assets/image_1749450038105.png)
+
+5. 配置“校验方式”、“触发方式”并“保存”规则。
+
+   * 校验方式【4】：本示例中我们计划监控 test_json 表中的 c1_id 字段取值非空，所以选择“单值指标取值校验”即可；“指标取值变动校验”会比较两个指标，并校验变化值。产品内置了诸多指标规则，开箱即用。这里选择字段空值数、选定字段名称、期待结果设定为等于0。
+
+   * 触发方式【5】：如字面含义，产品提供定时触发、周期调度任务触发和手动触发三种方式。周期任务触发会与调度系统绑定，在任务调度实例运行完成后即可触发质量规则的执行，能使校验更及时。对于生产场景，推荐使用这种方式。尤其是“强阻塞调度”选项，可以在质量规则校验失败时，阻塞整个调度流程，防止质量问题扩散。选择这种方式时，需要选择绑定的调度任务（即产出该数据表的任务）。
+
+   * 其他配置项保留默认值或留空即可。最后点击“保存”【6】按钮，完成质量规则的新建。
+
+   ![](.topwrite/assets/image_1749450069308.png)
+
+6. 创建完成后，在质量规则列表页面可以看到新增的规则。
+   ![](.topwrite/assets/image_1749450081238.png)
+
+7. 可以点击“试跑”按钮来测试质量规则的配置和校验情况。在“校验结果”Tab页可以查看具体结果，如下图所示：质量规则被触发运行，校验结果与预期一致，一切正常。
+   ![](.topwrite/assets/image_1749450092151.png)
+   ![](.topwrite/assets/image_1749450096317.png)
+
+8. 等待调度任务的定时到达后，观察质量规则触发情况。
+
+   * 在「任务运维」中，通过周期任务实例运行的日志，可以查看质量规则的触发运行情况。
+     ![](.topwrite/assets/image_1749450116093.png)
+
+   * 在「数据质量」的“校验结果”中，可以看到新增的校验记录，触发方式为“周期任务触发”。
+     ![](.topwrite/assets/image_1749450124984.png)
+
+9. 至此，已经完成了质量规则的配置和校验运行情况的观察。在完成数据质量规则配置后，如果需要及时收到质量规则校验失败的监控告警信息，还需进行监控配置，具体操作在此略过，详见 [数据质量](DataQuality.md) 的帮助文档。
+
+## 相关文档
+
+* 您可以阅读 [数据质量](DataQuality.md) 的帮助文档来了解数据质量模块的完整使用指南。
+
+## 下一步建议
+
+* 完成质量规则的配置后，可以参考 [如何快速配置和使用监控告警规则](quick_start_monitoring_and_alerting.md) 的指南文档，对质量规则的校验结果和任务运行状态等，配置监控规则、发送告警。

+# 入门指南：如何快速配置编排和周期调度ETL流程
+
+## 适用场景
+
+数仓工程师主要工作之一是构建离线数仓，即创建和维护周期调度ETL流程。本文会概要介绍如何基于 Lakehouse Studio 来配置和编排 ETL 任务，并配置调度属性，使得整个 ETL 流程能够被定时、按照依赖关系调度运行。
+
+## 前置阅读

+### SQL任务的创建
+
+1. 通过下图的操作入口，来创建一个 SQL 任务：
+
+   ![](.topwrite/assets/image_1748425848352.png)
+
+2. 在创建任务的弹框中，将任务命名为“SQL_DWS_聚合”，并单独创建一个名为“数据处理”的文件夹。
+
+   ![](.topwrite/assets/image_1748425859150.png)
+
+3. SQL 任务新建好后，如下图所示，在编辑区可以编写具体的 SQL 代码。
+
+   ![](.topwrite/assets/image_1748425869532.png)
+
+4. 前面通过数据同步任务，已经把 MySQL 的数据同步到 Lakehouse 的 test_json 表中。在 SQL 任务中，基于这张表中的数据进行聚合处理，比如把表中的 c2_tinyint_column、c3_smallint_column 两个字段分别求和。导航到“数据” Tab 页，定位到目标表 test_json，然后在操作栏中点击“数据查询”，可以自动将 SELECT 代码模板插入到编辑器中，如下图所示，这有助于提升代码编写效率。
+
+   ![](.topwrite/assets/image_1748425911494.png)
+
+5. 基于上述代码模板修改为所需的处理逻辑，然后保存。此处仅为示意，进行了简化处理，聚合结果未写入新表。
+
+   ![](.topwrite/assets/image_1748425934078.png)
+
+   ```SQL
+        SELECT   SUM(c2_tinyint_column),         
+                 SUM(c3_smallint_column),
+        FROM     test_json;
+   ```
+
+### 任务编排和调度配置
+
+完成同步任务和 SQL 任务的创建后，要构建完整的离线周期处理 ETL 流程，还需要配置调度定时和任务依赖关系。
+
+1. 打开同步任务，通过页面的“调度”按钮，打开调度属性的配置。
+
+   ![](.topwrite/assets/image_1748426012421.png =633)
+
+2. 配置调度时间：配置成每天调度、执行多次、每一个小时调度一次，如下图所示。通过“预览调度时间”可以查看基于配置对应的具体定时时间。
+
+   ![](.topwrite/assets/image_1748426023159.png =722)
+
+   ![](.topwrite/assets/image_1748426030471.png =397)
+
+3. 配置实例信息：这里主要需要配置“实例重跑方式”。由于本任务不存在重跑后产生数据不幂等的问题，可以重跑，因此选择“运行成功或失败，都可以重跑”，其他属性使用默认值即可。
+
+   ![](.topwrite/assets/image_1748426041609.png =386)
+
+4. 配置调度依赖：同步任务是流程中的第一个任务，没有上游依赖，此处留空即可。
+
+   ![](.topwrite/assets/image_1748426049779.png =386)
+
+5. 配置任务产出：任务产出用于描述本任务写入的是哪张表，以便下游任务在消费此表时，能智能识别到对应的上游任务。点击“智能解析”按钮，系统会通过任务配置自动解析出当前任务的产出表并回填到配置中。
+
+   ![](.topwrite/assets/image_1748426056766.png =386)
+
+6. 完成上述调度配置后，点击页面右下角的“确定”按钮将配置保存。回到任务页面，如下图所示，“提交”按钮会变成可点击的状态。
+
+   ![](.topwrite/assets/image_1748426062758.png)
+
+7. 点击“提交”按钮，在弹窗中二次核对信息无误后，再点击确定，同步任务即被提交到生产环境进行定期调度运行。
+
+   ![](.topwrite/assets/image_1748426068998.png)
+
+8. 切换到 SQL 任务，通过页面的“调度”按钮，打开调度属性的配置，需要配置的属性和同步任务相同，即：
+
+      1. 配置成一天调度多次、每小时调度一次。
+      2. 重跑属性配置成“运行成功或者失败，都可以重跑”。
+      3. 请特别注意需要配置 SQL 任务对同步任务的依赖关系。点击页面上的“智能解析”按钮，会自动识别 SQL 任务所依赖的同步任务并自动回填；也可以手动添加。
+      ![](.topwrite/assets/image_1748426078453.png =386)
+
+9. 同上，SQL任务的调度配置完成后，点击页面右下角的“确定”按钮将配置信息保存下来。回到任务页面，点击“提交”按钮把SQL任务也提交做定时调度。
+
+   ![](.topwrite/assets/image_1748426087176.png)
+
+10. 进入“任务运维”查看实际效果，有两种方式进入：
+
+    * 方式一：通过左侧导航 运维监控 > 任务运维
+
+    * 方式二：在任务上直接点击“运维”按钮，可直达运维中心中该任务的详情页，建议使用此方式。
+
+      ![](.topwrite/assets/image_1748426094142.png)
+
+11. 查看任务的详情，如下图所示，和预期一致，SQL任务依赖了同步任务：
+
+    ![](.topwrite/assets/image_1748426100418.png)
+
+12. 点击“任务实例”Tab，可以看到任务对应的具体实例的列表，实例已按照配置的定时时间生成（只生成任务提交时间之后的实例）：
+
+    ![](.topwrite/assets/image_1748426139524.png)
+
+13. 点击实例 ID 可以进入实例的详情页面进行查看。在定时时间到达后，上游的同步任务实例先运行，运行成功后，下游的 SQL 任务实例才会开始运行。实例触发运行需要同时满足两个条件（充分必要条件）：实例自身的定时时间已到达，且上游实例处于运行成功状态。
+
+    ![](.topwrite/assets/image_1748426146577.png)
+
+14. 至此就完成了一个完整的ETL流程的编排构建，并提交进行周期调度、运行。

+# 入门指南：如何快速配置和使用监控告警规则
+
+## 适用场景
+
+如果您配置了ETL流程，比如完成了前文的 [入门指南：如何快速配置编排和周期调度ETL流程](quick_start_etl.md)，计划对任务运行的稳定性和产出的数据质量检查增加监控，并在出现异常时发送告警通知，建议阅读此指南。
+
+## 前置阅读
+
+在阅读本指南之前，建议完成以下文档的阅读和理解：
+
+* [Lakehouse 产品简介](what_is_clickzetta_lakehouse.md)
+* [产品基本概念](Key_Concepts.md)
+* [Lakehouse Studio 快速导览](LakehouseStudioTour.md)
+
+## 操作指南
+
+Lakehouse Studio的「监控告警」产品模块，提供了一套强大的功能，它允许用户通过系统内置的规则或自定义规则，对任务运行状态等关键指标进行实时监控。一旦检测到异常情况，系统将发送及时的告警通知，帮助您确保数据流的稳定性和可靠性。
+
+### 使用说明
+
+具备 `工作空间管理员角色（workspace_admin）`、`工作空间开发角色(workspace_dev)` 或者 `工作空间运维角色(workspace_sre)` 的用户，可以使用「监控告警」功能。
+
+### 操作步骤
+
+#### 进入监控告警模块
+
+1. 如下图所示，点击按钮进入Lakehouse服务实例：
+   ![](.topwrite/assets/image_1748337538227.png)
+
+2. 导航到「运维监控」>「监控告警」页面：
+   ![](.topwrite/assets/image_1749455648524.png)
+
+#### 使用内置规则
+
+如上文所述，产品内置了全局的监控规则可供选择启用。
+
+1. 如下图所示，主要内置了“周期任务实例运行失败”和“数据质量检测失败”两类监控规则：
+
+   ![](.topwrite/assets/image_1749455660655.png)
+
+2. 点击具体的监控规则，可以查看其详细的配置定义。以“数据质量检测失败-强规则”为例，下图展示了其监控事项、告警通知方式和通知人员等核心信息。
+   ![](.topwrite/assets/image_1749455672982.png)
+
+   * 监控事项：强阻塞调度的质量规则校验失败。
+   * 告警通知：严重等级的规则，按照通知策略的定义（此处不展开，详见相关文档），会通过电话推送告警。
+   * 通知人员：默认会通知给对象责任人。对于数据质量规则，默认通知给规则创建人。
+
+3. 启用内置的全局告警规则和订阅，继续以“数据质量检测失败-强规则”为例：
+   ![](.topwrite/assets/image_1749455707588.png)
+   * 点击“开启”即可启用此规则[1]。按照规则定义，本告警会通知到对象责任人，即质量规则的创建人。
+   * 如果您不是对象责任人（比如不是质量规则的创建人），但也想关注此告警，可以点击“订阅”按钮[2]。
+
+#### 自定义监控规则
+
+内置规则主要从全局维度进行整体监控，方便快速使用。但在实际情况下，对于一些特殊对象，也存在单独配置精细化监控的诉求。这种情况下需要使用自定义监控规则的能力。
+
+下面的示例将展示如何监控特定周期调度任务的实例运行失败并通过电话告警，主要操作步骤如下：
+
+1. 在“监控规则”列表里面，点击“新建规则”按钮。
+   ![](.topwrite/assets/image_1749455842124.png)
+
+2. 在新建规则的弹框中，填写规则的必填信息、保存。
+   * 监控事项：任务实例运行失败。通过过滤项，**选择具体的任务名称**。
+   * 告警通知：等级设定为“警告”，选用“通用通知策略”来发送短信告警。通知人员默认会选择当前操作人。
+     ![](.topwrite/assets/image_1749455860120.png)
+     ![](.topwrite/assets/image_1749455865473.png)
+
+3. 规则创建后，在列表中会展示出一条记录：
+   ![](.topwrite/assets/image_1749455912549.png)
+
+4. 观察监控规则的工作情况。
+
+   * 这里进行一次模拟的错误变更：修改被监控任务的SQL逻辑，使用一个错误字段名，然后提交调度运行，以触发一个调度实例运行失败。
+     ![](.topwrite/assets/image_1749455960285.png)
+     ![](.topwrite/assets/image_1749456300165.png)
+
+   * 任务被调度运行、出现失败后，在「监控告警」中可观察到监控告警规则的工作情况，符合预期：
+     * 在“告警事件”中，可以看到新增了一条告警事件：
+       ![](.topwrite/assets/image_1749456335722.png)
+     * 在“通知历史”中，可以看到具体的告警通知推送情况：
+       ![](.topwrite/assets/image_1749456370821.png)
+
+至此，已经完成了监控告警内置规则和自定义规则的配置和实际工作效果观察。
+

+# 入门指南：如何快速运行一条SQL
+
+## 适用场景
+
+Lakehouse 提供了一体化的引擎来支持数据的处理、加工和分析，其开发语言为 SQL。本文概要介绍如何通过Lakehouse Studio的任务开发功能模块快速编写和运行一条SQL语句来进行查询分析。
+
+## 前置阅读
+
+在阅读本指南之前，建议完成以下文档的阅读和理解：
+
+* [Lakehouse 产品简介](what_is_clickzetta_lakehouse.md)
+* [产品基本概念](Key_Concepts.md)
+* [Lakehouse Studio 快速导览](LakehouseStudioTour.md)
+
+## 操作指南
+
+如果要快速在界面运行一条 SQL，需要使用 Lakehouse Studio 的数据开发模块，有两种方式：
+
+### 方式一：基于样例SQL和样例数据来运行
+
+产品中内置了开箱即用的样例代码和与之配套的样例数据。在页面导航，点击“开发”进入数据开发界面后即可看到 `Tpch_100g` 文件夹下的样例代码，这些样例代码演示了如何基于 Tpch\_100g 样例数据来编写SQL进行快速查询分析，如下图所示：
+
+![](.topwrite/assets/image_1747993124883.png)
+
+双击一个样例代码文件打开后，点击页面右上角的“运行”按钮，即可触发 SQL 的执行。执行完成后，在页面右下方可以查看执行结果和日志。
+
+![](.topwrite/assets/image_1747993372483.png)
+
+^
+
+请特别注意页面右上角的**集群**选项。“集群”是“计算集群”的简称，是 Lakehouse 提供算力的核心概念，可参考 [此文档](virtual-cluster.md) 进行详细了解。工作空间创建后，会默认初始化两个集群：名为 `DEFAULT ` 的通用型集群和名为 `DEFAULT_AP ` 的分析型集群。这两类集群针对不同的作业负载有对应的优化：
+
+* 通用型（GENERAL PURPOSE，简称 GP）：适用于处理离线作业，作业之间共享计算资源，新旧作业采用公平调度方式分配计算资源。适用于周期定时调度任务来处理大批量数据。
+* 分析型（ANALYTICS PURPOSE，简称 AP）：具备多计算实例和自动弹缩功能，适合处理在线和高并发作业。如果您想体验更强的数据查询性能，请选择此类型的集群。此外，AP 集群会对数据进行智能缓存。经过第一次查询后，后续查询的速度会更快。下图展示了这个差异：
+
+  ![](.topwrite/assets/image_1748326696659.png)
+
+^
+
+您也可以通过阅读 [使用样例数据快速开始查询分析](sample-data-using.md)，进一步了解如何基于样例数据进行查询分析。
+
+### 方式二：自己编写SQL并运行
+
+除了使用样例代码和样例数据之外，您也可以自己编写 SQL 并运行。在页面导航栏，点击“开发”进入数据开发界面，在“任务”下，通过新建菜单，选择“SQL脚本”来创建一个 SQL 任务文件。
+
+![](.topwrite/assets/image_1721484292583.png)
+
+在任务文件中，可按以下步骤编写和运行 SQL：
+
+1. 在页面上选择正确的数据 Schema。编写代码时，对于该 Schema 下的表的引用，直接写表名即可；否则，需要使用 `schema.table` 两段式或 `workspace.schema.table` 三段式格式来引用表。通常使用系统默认 Schema 即可。
+
+2. 在代码编辑区域填写需要运行的 SQL。
+
+3. 选择恰当的计算集群类型。对于 ad-hoc 临时查询，或者需要获得更快的查询响应速度，建议选择分析型（AP）集群。通用型（GP）集群适合大批量数据的离线、周期性调度任务的处理分析。
+
+4. 点击左侧的运行按钮或右上角的运行按钮来执行代码。左侧按钮只执行光标所在的代码块。右上角的按钮默认执行全部代码；也可以先选择部分代码，然后点击右上角的运行按钮来执行所选部分。
+
+   ![](.topwrite/assets/image_1721484303315.png)
+
+5. 运行完成后，在页面下方区域可以查看运行结果、耗时和运行日志等信息：
+
+   ![](.topwrite/assets/image_1721484312151.png)
+
+6. 在编辑框编写代码时，也可以切换到“数据”标签页，来快速浏览和使用数据。找到所需使用的表后，在操作菜单中可快速插入表的名称、字段名称，或者直接生成查询样例 SQL：
+
+   ![](.topwrite/assets/image_1721484321409.png)
+
+### 其它常用操作
+
+除了“运行”操作，系统还提供如下图所示的功能：
+
+1. 全局代码检索：通过代码关键字来查找文件
+2. 保存：保存当前文件修改的内容
+3. 格式化：对当前代码进行格式化排版
+4. 版本历史：可以查看文件的历史版本，并支持对比和回滚
+5. 查找：在当前文件内部通过关键字查找代码片段
+6. 快捷键：展示支持的常用快捷键
+
+![](.topwrite/assets/image_1721531293556.png)
+
+## 限制说明
+
+* 权限控制：需要具备 `工作空间管理员角色（workspace_admin）` 或者 `工作空间开发角色(workspace_dev)` 权限的用户，才能使用任务开发功能并运行 SQL。

+# 使用工作空间构建数据开发环境
+
+## 基本概念
+
+工作空间（workspace）是 Lakehouse 产品中的核心概念之一。它用于组织 Lakehouse 资源对象（如数据对象、计算资源），并提供相对隔离的数据开发、调度任务管理和运维环境。
+
+为了实现一个服务实例内的工作空间既相互隔离，又便于进行数据交换，不同工作空间之间的权限相互隔离：一个服务实例用户需要被某个工作空间的空间管理员角色（workspace\_admin）添加进入该工作空间，才可被授权并使用工作空间内的数据或计算资源。
+
+当一个用户具备某工作空间内的数据对象权限时，可以在其他工作空间对这些数据对象进行跨空间的查询或其他权限范围内的操作。
+
+:-: ![](.topwrite/assets/workspace_1735992503899.png =814)
+
+如上图所示，一个 Lakehouse 服务实例内可以创建多个工作空间。一个服务实例用户可以被同时添加进入多个工作空间，并被授予这些工作空间内对象的权限。
+
+以上图中的对象为例，介绍工作空间的隔离和数据互通方式：
+
+当上图中的用户user\_a同时被加入了工作空间A(workspace\_a)和工作空间B(workspace\_b)，并被授予了A和B两个工作空间的计算集群使用、数据对象查询等所需的权限。那么user\_a在工作空间A内的任务脚本demo\_script\_ws\_a和工作空间B内的任务脚本demo\_script\_ws\_b中执行以下语句均可正常得到查询结果。
+
+```
+select * from table workspace_a.schema_a.table_a limit 10;
+```
+
+而用户user\_b仅被加入了工作空间B(workspace\_b)，并授予了工作空间B内的一系列权限，当执行任务脚本demo\_script\_ws\_b对workspace\_a.schema\_a.table\_a进行查询时，会提示user\_b并不具备该表的select权限。
+
+## 使用场景
+
+一个服务实例（instance）中可以创建多个工作空间，您可以根据自身业务需要选择使用单一工作空间或多个工作空间。单一工作空间有利于管理，更方便对数据资产和计算资源进行统一管理；多个工作空间有利于在多个团队或项目间实现天然的权限、数据和计算资源边界。
+
+## 使用单一工作空间
+
+当您处于以下使用场景时，推荐仅使用默认开通的工作空间作为单一工作空间来使用 Lakehouse：
+
+* **个人或小型团队**：团队人数较少，数据与计算规模也不庞大，希望在同一个环境内进行协作和管理。
+* **单一产品线或业务部门**：只需管理一个业务域的数据与数据处理流程，对数据与访问控制的精细拆分需求相对较低。
+
+服务实例开通后，系统默认会创建一个名为“quick\_start”的工作空间。您可以直接使用此工作空间进行任务开发等工作。
+
+在管控中心的“账户主页”中，点击开通的服务实例，可进入服务实例的首页。
+
+:-: ![](.topwrite/assets/image_1721463116737.png =745)
+
+在服务实例的首页，点击左侧功能菜单中的“开发”、“计算”、“运维监控”等任意功能，页面右上角会列出当前账号具备权限访问的工作空间，支持切换。使用单一工作空间时，默认处于服务实例内仅有的一个工作空间中。此时所有的任务脚本、调度作业都处于该工作空间内。
+
+:-: ![](.topwrite/assets/image_1721463152612.png =743)
+
+## 创建并使用多个工作空间
+
+当您处于以下使用场景时，推荐创建并使用多个工作空间：
+
+* **跨部门或多项目隔离**：当业务部门或项目之间需要数据和资源访问隔离时，可通过多个工作空间实现天然的权限边界。
+* **安全与合规要求高**：金融、医疗、政府机构等对数据安全、合规和可审计性要求很高的行业场景，需要通过强隔离的方式加强数据安全。
+* **不同的计费或预算中心**：如果多个部门或项目分别有独立的预算，则各自独立的工作空间便于进行财务结算和成本追踪。
+
+服务实例的实例管理员（instance\_admin）角色可以创建工作空间。操作方式如下：
+
+进入“管理-工作空间”菜单，在工作空间管理页面中点击“新建空间”，填写所需信息后进行创建。
+
+:-: ![](.topwrite/assets/image_1721463203358.png =794)
+
+^
+
+工作空间的名称一经创建，不允许变更。新的工作空间会默认创建一个名为“public”的 schema，以及 3 个不同类型的计算集群（通用型计算集群、分析型计算集群和同步型计算集群），便于快速在工作空间中开始操作。
+
+新建工作空间的用户会默认被授予这个工作空间的空间管理员（workspace\_admin）角色。
+
+使用多个工作空间时，可在“开发”、“计算”、“运维监控”等功能页面中，通过右上角的工作空间按钮，切换不同工作空间环境进行使用。
+
+:-: ![](.topwrite/assets/image_1736089880260.png =785)
+
+^
+
+一个服务实例用户如需使用某个工作空间中的数据和计算资源，需要被加入该工作空间并被授予相应的权限。这一操作需要具备该工作空间的空间管理员角色（workspace\_admin）用户来执行。更多操作说明请参考“访问控制”-“配置访问控制”中的[工作空间级管理](access-control-configration.md)的相关内容。

+# 数据分享
+
+## 1. 概述
+
+### 什么是数据分享（Data Share）
+
+数据分享是云器 Lakehouse 提供的 **无复制** 数据共享功能，可在同一服务区域内实现 **跨账户或跨服务实例** 的数据授权与使用。与传统的数据复制或导入方案不同，数据分享不需要在企业间手动搭建数据同步链路，而是通过“授权”方式直接提供对源数据的只读访问，且实时更新。
+
+### 应用场景
+
+* **实时共享场景**：A 企业将自身数据（例如交易日志、用户行为数据）实时共享给 B 企业，B 企业不需要做数据同步即可实时查询更新数据。
+* **多方协作分析**：多家合作方基于同一份实时数据进行分析、挖掘，减少重复存储和传输成本。
+* **数据提供商与数据消费者模式**：数据提供方希望将部分数据开放给合作伙伴，合作伙伴无需承担存储成本即可获得只读数据，用于自有的 BI 分析或产品集成。
+
+### 本文案例
+
+本文将以 **A 企业**（数据提供方）和 **B 企业**（数据接收方）为例，介绍以下操作：
+
+1. **A 企业创建 Data Share 并分享数据**：A 企业在自身数仓中拥有Brazil\_Commercial的电商数据，希望将脱敏后的数据纳入到 Data Share 中，指定分享给 B 企业。
+2. **B 企业接收并提取 Data Share 中的数据**：B 企业在自己的云器 Lakehouse 实例中，收到A企业的分享并创建对应的 schema 来提取共享数据。
+3. **B 企业使用提取的数据关联 BI 应用，制作报表**：B 企业基于 Data Share 提取出来的只读数据进行分析，在 BI 工具中制作报表。
+4. **A 企业写入数据，B 企业的报表实时获取数据变更**：由于 Data Share 无复制且实时，A 企业对数据所做的更新可以在 B 企业第一时间可见。
+
+***
+
+## 2. A 企业创建数据分享并指定企业B进行接收
+
+以下示例中，A 企业有物流情况表rpt\_brazil\_ec，其中包含所有销售方所有产品的物流状态。B企业是A企业其中的一个销售方（seller），A企业需要向B企业提供其销售产品的物流状态，以便B企业使用这些数据做BI看板，分析和跟踪物流状态。为此，A 企业将对 rpt\_brazil\_ec进行数据过滤，创建一个仅包含B企业数据的视图 `sub_rpt_brazil_ec_05e107217c7266362fd44b75b2cd4cc4`，并将该视图分享给企业B。
+
+### 2.1 创建视图
+
+因物流情况表rpt\_brazil\_ec中包含所有销售方的数据，出于数据安全考虑，不可将所有数据提供给B企业。所以需要先创建一个视图，仅包含B企业的数据，并仅分享这个视图。
+
+表rpt\_brazil\_ec中包含销售方ID字段：seller\_id，以这个字段作为过滤条件创建以下视图：
+
+```
+--为share创建独立的schema，便于后续管理和维护
+CREATE SCHEMA seller_data_share;
+​
+--创建视图，这里假设企业B的seller_id为05e107217c7266362fd44b75b2cd4cc4
+CREATE    VIEW seller_data_share.sub_rpt_brazil_ec_05e107217c7266362fd44b75b2cd4cc4 AS
+SELECT    *
+FROM      rpt_brazil_ec
+WHERE     seller_id = '05e107217c7266362fd44b75b2cd4cc4';
+```
+
+### 2.2 创建数据共享并分享给指定企业B
+
+#### Web 界面操作
+
+**1）创建数据分享**
+
+* 使用具备“实例管理员”（`instance_admin`）角色的账号登录云器 Lakehouse 控制台。
+* 左侧导航选择“数据” → “数据分享”，点击“+新增分享”。
+
+:-: ![](.topwrite/assets/image_1740388043727.png =742)
+
+* 在弹窗中填写分享名称（如 shipping\_detail），选择待分享数据所在的工作空间。
+* 注意，待分享数据需在同一个工作空间内。如果数据本身分布在多个工作空间，可以在一个工作空间内创建其他空间待分享数据的视图，以集中所有待分享数据到同一工作空间。
+
+:-: ![](.topwrite/assets/image_1740388342928.png =438)
+
+**2）添加要分享的数据对象**
+
+继续在新建分享的弹窗中，点击“添加”，选择要分享的对象。如下图，在ql\_ws空间下找到上文创建的schema：seller\_data\_share，勾选其中的视图：seller\_data\_share.sub\_rpt\_brazil\_ec\_05e107217c7266362fd44b75b2cd4cc4
+
+点击“完成”后，该视图即被纳入分享列表。
+
+:-: ![](.topwrite/assets/image_1740388392799.png =537)
+
+^
+
+**3）配置接收实例**
+
+在同一个弹窗中，点击“接收实例”下方的“添加”按钮，输入 B 企业的云器 Lakehouse “服务实例名称”（需要B企业提供，在其登陆服务实例后的首页右上方），并点击完成。
+
+:-: ![](.topwrite/assets/image_1740388438814.png =531)
+
+^
+
+**4）完成数据分享创建**
+
+完成上述所有内容填写后，点击“确定”按钮，即完成数据分享对象的创建，并指定分享给了企业B的Lakehouse服务实例。
+
+后续还可对该数据分享进行编辑，增减需要分享的数据对象，或增减接收此数据的Lakehouse服务实例（比如需要给B企业的其他服务实例）。
+
+**5）查看或管理分享对象**
+
+创建完成后，可以在“数据分享” → “我分享的”列表中看到刚创建的数据分享对象。
+
+:-: ![](.topwrite/assets/image_1740390203623.png =718)
+
+^
+
+#### SQL 操作
+
+若更偏好 SQL 操作，则请使用具备 “实例管理员”（`instance_admin`）角色的账号，在 A 企业的工作空间（如 `ql_ws`）下执行以下操作：
+
+**1) 创建 Share**
+
+```
+CREATE SHARE shipping_detail;
+```
+
+**2) 将视图纳入 Share**
+
+```
+--注意，select赋予接收者查询数据的能力，read metadata赋予接收者可见这个view对象的能力，两个权限点均需要授予。
+GRANT SELECT, READ METADATA ON VIEW seller_data_share.sub_rpt_brazil_ec_05e107217c7266362fd44b75b2cd4cc4 TO SHARE shipping_detail;
+```
+
+**3) 配置分享目标实例**
+
+```
+ALTER SHARE shipping_detail ADD INSTANCE '<替换为B企业的instance_name>';
+```
+
+其中需要由 B 企业提供其Lakehouse服务实例的名称。此操作后，B 企业将立即获得share shipping\_detail的使用权，并可从其中提取view：seller\_data\_share.sub\_rpt\_brazil\_ec\_05e107217c7266362fd44b75b2cd4cc4
+
+的只读访问权限。
+
+> 完成以上步骤后，A 企业即已成功将过滤后的数据通过数据分享功能分享给 B 企业。
+
+##
+
+### 2.3 B 企业接收并提取 Data Share 中的数据
+
+在完成 A 企业分享后，B 企业需要在自己的云器 Lakehouse 实例中“接收并提取”分享数据，才能在查询中使用到该视图对象。
+
+#### Web 界面操作
+
+**查看分享给我的对象**
+
+登录 B 企业的云器 Lakehouse 控制台，使用具备“实例管理员”或“工作空间管理员”角色的账号。
+
+左侧导航选择“数据管理” → “数据分享”，切换到“分享给我”页签，即可看到 A 企业分享过来的 shipping\_detail。
+
+^
+
+**提取数据**
+
+在 shipping\_detail 卡片下方点击“提取”按钮。
+
+弹窗中选择“源 schema”（一个数据分享中可能包含多个schema，需要指定schema进行数据提取），以及想要将共享数据落到 B 企业服务实例下的哪个工作空间及对应 schema。
+
+注意，这里会根据填写的schema名称新建对应的schema，且该schema为只读，不可在此schema下创建其他table或view等数据对象。
+
+完成填写后，点击“确定”按钮，系统会在 B 企业的指定工作空间中新建只读 schema，并映射到 A 企业分享的对象。
+
+^
+
+**完成提取后**
+
+B 企业可以在“数据目录”或“开发”功能的“数据”页签中，看到对应的新 schema，并看到view：sub\_rpt\_brazil\_ec\_05e107217c7266362fd44b75b2cd4cc4。
+
+可像使用本地数据对象一样，对view中的数据进行查询操作。
+
+^
+
+### 2.4 SQL 操作
+
+如果使用 SQL提取share中的数据，在 B 企业的工作空间中执行以下命令：
+
+**查看分享对象**
+
+```SQL
+SHOW SHARES;
+```
+
+可查看到 `INBOUND` 类型的，名称为shipping\_detail 的数据分享，来自 A 企业的服务实例。
+
+**查看shipping\_detail中有哪些数据**
+
+```
+DESC SHARE shipping_detail;
+```
+
+^
+
+**创建本地 Schema**&#x20;
+
+```
+CREATE SCHEMA b_workspace_share_schema FROM SHARE A_instance_name.shipping_detail.share_demo;
+```
+
+其中 `A_instance_name`、`share_demo` 以及源 schema 名可通过 `SHOW SHARES;` 和 `DESC SHARE share_demo;` 查询到。
+
+`b_workspace_share_schema` 为在 B 企业工作空间中新建的只读 schema 名称，可自定义。
+
+^
+
+***
+
+## 4. B 企业使用提取的数据关联 BI 应用制作报表
+
+B 企业提取并成功创建了只读 schema 后，即可在任意兼容云器 Lakehouse 的 BI 工具或 SQL 工作台中，对 `orders_view` 进行查询或关联分析。例如：
+
+```
+SELECT 
+    order_id,
+    customer_id,
+    order_amount,
+    order_status
+FROM b_workspace_share_schema.orders_view
+WHERE order_status = 'COMPLETED';
+```
+
+* **关联外部数据**：可将 `orders_view` 与 B 企业内部自有数据表进行关联（`JOIN`）分析。
+* **数据建模**：可在 BI 工具中将 `orders_view` 作为数据源进行数据可视化与报表制作。
+
+此时，B 企业已经不需要关心数据是否实时同步——Data Share 保证了当 A 企业源数据更新时，B 企业查询到的就是最新的数据。
+
+***
+
+## 5. A 企业在 Data Share 中写入数据，B 企业报表实时查询变更
+
+当 A 企业往 `orders_view` 对应的底层表 `orders` 插入新数据，或者更新现有订单数据时，Data Share 会自动将变更后的数据实时暴露给 B 企业。B 企业无需额外操作，即可在 SQL 查询或 BI 报表中看到最新结果。
+
+示例：A 企业执行以下语句更新订单状态，B 企业在其已有的报表中就能立即看到状态更新后的记录。
+
+```
+-- A 企业在 workspace_a 中执行
+UPDATE orders
+SET order_status = 'SHIPPED'
+WHERE order_id = 10001;
+```
+
+B 企业通过之前的 BI 报表或下列 SQL 查询，实时获取最新状态：
+
+```
+-- B 企业执行
+SELECT 
+    order_id,
+    order_status
+FROM b_workspace_share_schema.orders_view
+WHERE order_id = 10001;
+```
+
+***
+
+## 总结
+
+通过以上 5 步操作，您可以在云器 Lakehouse 平台上实现类似 Snowflake Data Sharing 的实时数据共享。Data Share 最大的特点在于：
+
+* **无复制、低延迟**：无需在企业间重复存储或定期同步，数据变更可以实时传播给消费方。
+* **数据安全可控**：数据仅以“只读”形式分享，且随时可通过权限管控移除共享对象。
+* **易于扩展**：通过 View 可以灵活过滤数据列或行，实现精细化的分享控制。

+# 为团队快速搭建 Lakehouse 数据开发环境
+
+## 概述
+
+本文档旨在帮助您在最短时间内搭建一套可供团队共同使用的 Lakehouse 数据开发环境，环境中包括多个可登录并进行数据开发的用户身份，不同用户身份被授予不同的数据权限和角色，以保证必要的权限管控、资源配置和协作便利性。
+
+:-: ![](.topwrite/assets/lakehouse-data-sharing-new.svg =721)
+
+## 1. 准备工作
+
+1. **开通云器账号**
+
+   如果您还没有云器账号，可以前往 [云器官网](https://www.yunqi.tech/) 注册获取。开通注册方式可参考[开通使用](setup.md)。
+
+2. **创建Lakehouse服务实例**
+
+   您需要至少已创建一个Lakehouse服务实例。如还未开通服务实例，可参考：[开通使用](setup.md)中的“创建Lakehouse服务实例”说明进行操作。
+
+3. **拥有 Lakehouse服务实例的instance\_admin(实例管理员) 角色**
+
+   Lakehouse 的权限管理是基于角色（Role）的，创建Lakehouse服务实例的用户会默认具备该服务实例的instance\_admin（实例管理员）角色。
+
+## 2. 搭建完成后
+
+按照后续章节完成环境搭建后，您将得到以下环境：
+
+1. 一个Lakehouse服务实例下的独立工作空间；
+2. 多个可用的用户身份，并具备在工作空间下进行数据开发的权限；
+3. 一个SQL任务，并可提交为周期运行。
+
+***
+
+## 3. 操作步骤
+
+### 3.1 创建用户
+
+注册云器账户时，会默认创建该账户下的第一个用户，并具备账户下所有的操作权限。当团队中多人共同使用Lakehouse进行开发时，使用多个用户身份并区分权限，可以有效对数据和资源进行管理，增强安全性、降低操作冲突的风险，并能有效审计和追溯个人操作。
+
+为达到上述管理目的，需要为每个开发人员或每个集成服务创建独立的用户，以便为后续分配相应角色做准备。
+
+使用注册云器账户时的默认用户[登录](https://accounts.clickzetta.com/login)云器产品，进入管理中心页面，并切换至“用户管理”功能：
+
+:-: ![](.topwrite/assets/quickstart_team_p1.png =801)
+
+^
+
+点击右上角的“新建”按钮，选择“新建用户”，这里分别创建2个用户：developer 和 analyst，如下所示：
+
+:-: ![](.topwrite/assets/quickstart_team_p2.png =361)
+
+^
+
+:-: ![](.topwrite/assets/quickstart_team_p3.png =360)
+
+创建成功后，可以在用户管理的用户列表中看到这两个用户。
+
+### 3.2 创建工作空间
+
+在Lakehouse中，工作空间用于隔离计算资源和数据，形成相对独立的数据开发环境，避免资源冲突或误操作数据。开通Lakehouse服务实例后，系统会默认创建一个名为quickstart的工作空间（workspace）。这里为了完整介绍团队使用方式，我们创建另外一个工作空间：dev\_envirment：
+
+仍然使用注册账户时创建的用户登录，并在管理中心点击已开通的服务实例名称，进入服务实例首页。
+
+:-: ![](.topwrite/assets/quickstart_team_p4.png =797)
+
+^
+
+在服务实例首页中，依次点击左侧菜单中的“管理”-”工作空间“，进入工作空间管理页面。点击右上角的”+ 新建空间“按钮：
+
+:-: ![](.topwrite/assets/quickstart_team_p5.png =774)
+
+^
+
+在弹窗中输入工作空间的名称，点击“确定”，完成工作空间创建：
+
+:-: ![](.topwrite/assets/quickstart_team_p6.png =382)
+
+^
+
+:-: ![](.topwrite/assets/quickstart_team_p7.png =733)
+
+^
+
+### 3.4 创建schema和table
+
+在 Lakehouse 的工作空间中，schema 用于进一步归类数据表和视图。可根据团队规模和业务需求规划 schema 层级。以下先创建3个schema：STG、CORE和ADS。
+
+首先在新创建的dev\_envirment工作空间的右侧点击“开发”，进入开发页面，并执行以下SQL，创建schema：
+
+:-: ![](.topwrite/assets/quickstart_team_p8.png =730)
+
+^
+
+:-: ![](.topwrite/assets/quickstart_team_p9.png =736)
+
+在Schema STG中创建2张表，并插入部分样例数据：
+
+```SQL
+CREATE SCHEMA STG;   -- 数据源原始或暂存表存放
+CREATE SCHEMA CORE;  -- 核心事实表/维度表存放
+CREATE SCHEMA ADS;   -- 汇总或分析结果表存放
+
+
+----------------------------------------------------------
+-- 1. 在STG层创建示例表: EMPLOYEES
+----------------------------------------------------------
+CREATE TABLE STG.EMPLOYEES (
+    EMP_ID          INT,
+    EMP_NAME        VARCHAR(50),
+    DEPARTMENT      VARCHAR(50),
+    JOIN_DATE       STRING
+);
+
+-- 向表中插入一些示例数据
+INSERT INTO STG.EMPLOYEES (EMP_ID, EMP_NAME, DEPARTMENT, JOIN_DATE) VALUES
+    (101, 'Alice',    'Engineering', '2023-07-10'),
+    (102, 'Bob',      'Sales',       '2024-08-05'),
+    (103, 'Charlie',  'Finance',     '2024-09-01');
+
+----------------------------------------------------------
+-- 2. 创建示例视图: EMPLOYEES_OVERVIEW
+----------------------------------------------------------
+CREATE VIEW ADS.EMPLOYEES_OVERVIEW AS
+SELECT 
+    EMP_ID,
+    EMP_NAME,
+    DEPARTMENT,
+    JOIN_DATE
+FROM EMPLOYEES;
+```
+
+### 3.5 将团队成员加入工作空间并授权
+
+上文中创建的两个用户：developer 和 analyst，默认并不具备任何数据操作和资源使用的权限。需要经由具备工作空间管理员角色（workspace\_admin）的用户授权后，才可以进行操作。
+
+假设我们希望这两个用户各自的权限范围是：
+
+**developer用户**，可以使用“开发”功能；可以在dev\_environment工作空间下对所有数据进行读写操作，并可以创建和删除table、view等对象；可以使用dev\_environment工作空间下所有的计算集群资源；可以提交并维护dev\_environment工作空间下的周期任务。
+
+**analyst用户**，可以使用“开发”功能；对schema ADS 下的所有表和视图具备只读权限，对表stg.employees具备只读权限；可以使用dev\_environmentt工作空间下所有的计算集群资源。
+
+为了达到以上效果，需要继续使用创建dev\_environment工作空间的用户，打开“开发”功能，新建SQL脚本，并执行以下授权语句：
+
+```SQL
+----------------------------------------------------------
+-- 1. 为developer用户授权
+----------------------------------------------------------
+--将用户developer加入工作空间，仅加入工作空间后，才可以授予该工作空间下元数据对象的权限
+CREATE USER developer;
+
+--为用户developer授予workspace_dev角色,以具备以下权限“可以使用'开发'功能；可以在dev_environment工作空间下对所有数据进行读写操作，并可以创建和删除table、view等对象；可以使用dev_environment工作空间下所有的计算集群资源；”
+GRANT ROLE workspace_dev TO USER developer;
+
+--为用户developer授予workspace_sre角色，已具备“可以提交并维护dev_environment工作空间下的周期任务”的权限
+GRANT ROLE workspace_sre TO USER developer;
+
+
+----------------------------------------------------------
+-- 2. 为analyst用户授权
+----------------------------------------------------------
+--将用户analyst加入工作空间，仅加入工作空间后，才可以授予该工作空间下元数据对象的权限
+CREATE USER analyst;
+
+--为用户analyst授予workspace_analyst角色,以具备以下权限“可以使用'开发'功能；可以使用dev_environment工作空间下所有的计算集群资源；”
+GRANT ROLE workspace_analyst TO USER analyst;
+
+--为用户analyst授予单独授予部分数据权限，以实现“对schema ADS 下的所有表和视图具备只读权限”
+GRANT SELECT, READ METADATA ON ALL TABLES IN SCHEMA ads TO USER analyst;
+GRANT SELECT, READ METADATA ON ALL VIEWS IN SCHEMA ads TO USER analyst;
+
+--为用户analyst授予单独授予部分数据权限，以实现“对表stg.employees具备只读权限”
+GRANT SELECT, READ METADATA ON TABLE stg.employees TO USER analyst;
+
+```
+
+上述授权操作中，将用户加入工作空间和授予角色的操作也可以通过WEB页面操作完成。
+
+**web端加入工作空间操作**
+
+继续使用创建dev\_environment工作空间的用户，点击左侧菜单“管理”-“工作空间”，进入工作空间列表，找到dev\_environment工作空间，点击进入。在工作空间详情页面的“用户”页签右侧点击“+添加用户”按钮：
+
+:-: ![](.topwrite/assets/quickstart_team_p10.png =774)
+
+^
+
+在弹窗中找到用户 developer 并勾选（可以同时找到 analyst 用户，一起勾选。但是因为两个用户要授予的权限不同，此处分开操作，仅先添加 developer 用户）。
+
+:-: ![](.topwrite/assets/quickstart_team_p11.png =763)
+
+^
+
+此时下方有两个按钮，点击右边的“添加用户”，仅执行添加用户进入工作空间的操作，不做任何授权。点击左边的“添加用户并授予角色”，可以进一步选择要授予的角色。假设我们点击左边的“添加用户并授予角色”按钮：
+
+:-: ![](.topwrite/assets/quickstart_team_p12.png =772)
+
+^
+
+在可授予的角色中，我们选择“workspace\_dev"角色，勾选并点击”角色授予“。
+
+完成上述操作后，我们即完成了对用户developer的加入工作空间和授权操作。效果和上述SQL执行的授权等价。
+
+对用户analyst的授权操作，由于包含“单独授予部分数据权限”的操作，这部分操作推荐使用SQL的GRANT语句执行授权，更为便利。
+
+### 3.6 检查授权结果
+
+Lakehouse支持使用SHOW GRANTS语句查询用户已授予的权限。
+
+在“开发”功能中执行以下语句：
+
+```SQL
+SHOW GRANTS TO USER developer;
+```
+
+返回结果如下：
+
+:-: ![](.topwrite/assets/quickstart_team_p13.png =738)
+
+^
+
+### 3.7 团队成员登录系统
+
+完成上述操作后，developer和analyst两个用户均可以登录Lakehouse，并具备了相应的权限可以进行数据开发或查询。下面使用developer用户登录系统。
+
+回到云器的登录页面<https://accounts.clickzetta.com/login>，依次输入账户名称、用户名和密码。其中账户名称在账号注册成功后提供，并可在该账户任意用户登录后的 URL 中获取。
+
+:-: ![](.topwrite/assets/quickstart_team_p15.png =746)
+
+现在使用developer用户，在<账户名称>.accounts.clickzetta.com/login URL登录，并点击“Lakehouse”产品下“进入”服务实例按钮，进入Lakehouse服务实例中。
+
+:-: ![](.topwrite/assets/quickstart_team_p16.png =740)
+
+### 3.8 团队成员编写开发任务
+
+developer用户登录后，在左侧菜单中进入“开发”页面。因当前developer用户只加入了dev\_envirment这一个工作空间，所以无需切换工作空间。如果加入多个工作空间，可以在右上角切换所需进行开发的工作空间。
+
+:-: ![](.topwrite/assets/quickstart_team_p17.png =739)
+
+^
+
+点击“开发”功能的“+”新建SQL脚本，写一条查询语句查询 stg.employees 表中的数据。
+
+:-: ![](.topwrite/assets/quickstart_team_p18.png =717)
+
+^
+
+```SQL
+select * from stg.employees limit 10;
+```
+
+:-: ![](.topwrite/assets/quickstart_team_p19.png =740)
+
+^
+
+依次点击“保存”按钮保存任务代码，点击“调度”按钮打开调度配置弹窗。
+
+:-: ![](.topwrite/assets/quickstart_team_p20.png =572)
+
+^
+
+在弹窗中配置调度任务的周期、重跑方式等信息，然后点击“确定”按钮，即完成该任务的调度配置操作。
+
+:-: ![](.topwrite/assets/quickstart_team_p21.png =730)
+

+
+成功配置调度后，“提交”按钮变为可点击状态。点击“提交”后，该任务即提交为周期调度运行。
+
+:-: ![](.topwrite/assets/quickstart_team_p22.png =695)

+# 低延迟实时湖仓数据集成和高性能实时分析
+
+本文档会介绍基于云器Lakehouse构建高稳定低延迟的实时湖仓数据集成方案和基于同一份湖仓数据的高性能实时分析两部分内容。
+
+## 概述
+
+随着企业业务的扩展，实时数据分析变得至关重要，它不仅是业务决策的支撑点，也是推动企业发展的必备条件。为了实现数据的实时分析，企业通常面临两种技术方案选择：
+
+* 直接利用业务数据库进行BI分析：这种方法操作简便，能够快速实施。然而，它在处理大规模数据和复杂查询时会遇到性能瓶颈，特别是在需要执行多表连接等复杂操作时，查询响应时间会显著延长，无法满足实时分析的需求。此外，出于对稳定性和安全性的考虑，业务数据库通常不允许直接用于数据分析，这限制了数据分析团队的操作空间。
+* 基于数据仓库的BI分析方案：该方案通过将数据从业务数据库同步到数据仓库，利用数据仓库的高性能处理能力来支持BI分析。这种方法有效解决了性能问题，但最大的挑战在于数据的实时性。传统的数据同步通常是T+1或H+1的批处理模式，无法满足业务对数据实时性的需求，往往还需要部署额外的OLAP引擎，这进一步增加了成本。
+
+云器Lakehouse提供了一种高稳定性、低延迟的实时湖仓数据集成解决方案，它能够实现从多种源端数据源（如MySQL、PostgreSQL、SQL Server等）的实时数据同步，并直接支持BI报表的实时查询。这种方案通过在数仓中维护同一份数据，既支持数据的实时写入，也支持BI报表的实时查询，消除了传统方案中需要额外部署OLAP引擎的需求。这样的设计简化了数据架构，降低了成本，同时确保了数据的实时性和查询效率，为企业提供了一种既经济又高效的实时数据分析解决方案。
+
+##
+
+## 实时湖仓数据集成
+
+此部分会展开介绍产品化的实时湖仓集成方案，如何便捷地将海量库表数据同步进入到Lakehouse湖仓。
+
+### 场景和数据描述
+
+本演示实践中，在源端MySQL数据库准备了四张各有 100 万行数据的表，计划将这 400 万行数据同步到目标云器Lakehouse的表中，然后直接使用 BI 报表进行查询分析。
+
+:-: ![](.topwrite/assets/image_1734675535069.png =570)
+
+^
+
+本演示以常见的 SaaS 服务模式为例，在多租模式下，数据库采取分库分表的结构，数据存在不同的分表；某些租户的信息会存在同一张分表内，且不同分表中包含特定租户的定制扩展字段，即源端是基本相同的四张分表，但部分表的字段存在细微差异，如下图所示，yellow\_taxi\_02 表，相比yellow\_taxi\_00表，多出了一个扩展字段 ext\_columm\_2 。
+
+:-: ![](.topwrite/assets/image_1734675556308.png =500)
+
+###
+
+### 前置准备：数据源配置
+
+导航到管理 -> 数据源，单击”新建数据源“并选择MySQL，即可创建本案例中所需的数据源。填写必须的配置信息，尤其请注意选择正确的数据库所在时区，实时同步对时区敏感，配置错误会使得同步失败。
+
+![](.topwrite/assets/image_1735208242938.png)
+
+源端数据库的权限等高阶配置，可以参考[此文档](realtime_sync.md)。
+
+### 实时同步任务的配置
+
+首先在任务开发里点击新建”多表实时同步任务“，选择正确的源端数据源类型，比如 MySQL。
+![](.topwrite/assets/image_1734939965441.png =630)
+
+实时同步任务提供两类数据同步模式：
+
+* 第一类：多表镜像同步，把源端的数据表，原原本本地镜像同步到目标端。
+* 第二类：多表合并同步，支持把源端多张表合并写入到目标端同一张表中，这也是本实践中用到的场景。源端数据量大、有分库分表的场景下，同步过程中把多张表合并写入到同一张表，在后续查询中就不再需要再进行多表JOIN、可以为查询提速。
+
+选择好同步模式之后，选择存储了源端连接串信息的数据源，如下图所示：
+
+![](.topwrite/assets/image_1734940034365.png)
+
+^
+
+接下来配置需要同步的数据对象。产品内提供了丰富的过滤规则来筛选源端表，比如命名的精确匹配、正则匹配等，可以按需使用。在源端表字段存在不一致的情况下，系统会自动检测进行识别、提示开启异构表合并同步功能。异构表合并同步功能作用是在目标端的表中，取源端表字段的并集进行建表，确保源端所有的数据能被同步写入到目标端。
+
+![](.topwrite/assets/image_1734949182748.png)
+
+配置完成后可以对具体的表的字段进行预览检查，确保扩展字段也被添加进来，保证数据一致。
+
+![](.topwrite/assets/image_1734952733442.png)
+
+如果使用镜像同步模式来代替多表合并模式，会把源端表的结构完整映射到目标表上，但还需要再进行 ETL 的处理加工、产出一张新的合并后的表供BI查询。增加表，也附带增加了一个处理链路，提升复杂度的同时会使得端到端的整个链路更长，数据新鲜度和时效性会大打折扣，成本也会提升。
+
+上文提到源端数据是采用分库分表的方式存储数据，但常常会遇到一种更复杂的情况：源端主键字段相同的取值的记录，在不同分表中的数据会出现重复。本示例中的数据也模拟设计了类似情况，在源端两张表同样的主键 ID 取值，在不同的表里分别会有一条记录，这会给同步过程带来了挑战：在合并写入到目标端时，如果是只按 ID 作为主键，这两条记录就会被尝试写入到一条记录中，会产生数据冲突的情况，两条源端的记录依据先后顺序被处理，后到的源端表中的数据被把先到的源端表中的数据给覆盖掉。面对这种情况，Lakehouse 实时同步方案中，提供了扩展字段的能力，来保证数据准确性。通过标识源端数据来源，比如将 server、databasename、 tablename 等字段设置为联合主键后，这两条数据在目标端会被当成两条记录来对待。通过这种方式，保证在即使源端出现分表中主键数据有重复的复杂情况下，源端数据也能被准确地同步到目标端。
+
+![](.topwrite/assets/image_1735208417539.png)
+
+完成上述配置后，下一步在“目标配置”里设定目标数据源类型、数据源名称等配置项。
+
+![](.topwrite/assets/image_1735205909270.png)
+
+接下来可以在映射关系中预览同步的字段配置，可以看到扩展字段包含在内，扩展字段/联合主键也在这里有所体现。
+
+![](.topwrite/assets/image_1735205869904.png)
+
+云器Lakehouse实时同步中，也提供了丰富同步规则策略，用来动态适配源端数据库的变更（Schema Evelution），比如源端表删除、新增字段等情况下的应对策略，以及需要处理的源端变更消息类型等。
+
+![](.topwrite/assets/image_1735205828392.png)
+
+到这里，整个实时同步任务就已经配置完成，只需要简单四步：**选择数据源、圈定源端同步对象、选定目标端，设定同步策略**。
+
+### 提交并启动数据实时同步
+
+云器Lakehouse提供了开发环境和生产环境两种模式，要将该任务在生产环境运行起来，需要先将其发布提交，然后在运维中心启动该任务。
+
+* 提交多表实时同步任务
+  ![](.topwrite/assets/image_1735206359814.png)
+
+* 运维多表实时同步任务
+  ![](.topwrite/assets/image_1735206291470.png)
+
+* 启动多表实时同步任务：启动时，可以根据实际需求，选择是否进行全量数据同步。首次同步的数据，通常建议选择做一次全量数据同步，然后再进行增量数据同步。
+  ![](.topwrite/assets/image_1735206439758.png)
+  ![](.topwrite/assets/image_1735206478684.png)
+
+任务启动后，在运维界面中，可以看到任务会进入全量同步阶段，数据已经写入 200 万行，速率在 25, 000+ 行/秒。
+
+![](.topwrite/assets/image_1734677235371.png)
+
+特别地，多表实时同步任务仅需要在第一次启动时对源端做一次全量同步，全量同步完成后，无需手动更改，任务会自动转入增量同步环节，保持数据的无缝衔接。
+
+### 验证数据变更的同步效果
+
+在实际应用中，经常会出现因为业务需要使得源端数据库的表和结构出现变化的情况，如源端表增加了字段，删除了字段、或者字段的类型变化了。对于这类情况，Lakehouse的实时同步也提供了对应的解决办法。
+
+云器Lakehouse产品支持直接操纵源端数据库，通过 SQL 来对源端数据库进行修改、查询等操作，首先我们对源端数据进行变更，先在源端添加一些新的字段：ext\_column\_0 & ext\_column\_1，并在源端表里删掉一个字段，同时更改一个字段类型从 int 改为 bigint 。
+
+![](.topwrite/assets/image_1734677264978.png)
+
+![](.topwrite/assets/image_1734677273784.png)
+
+![](.topwrite/assets/image_1734677283775.png)
+
+接下来可以在监控页面中看到，源端的数据变更已经被同步过来进行消费，基于在同步任务中配置的Schema Evelution规则，自动更新，无需手动操作进行其它额外配置、或者重启任务，这样能确保整个同步链路平滑运行。
+
+![](.topwrite/assets/image_1734677295827.png)
+
+同步完成后，也可以在任务运维界面中检查源端的变更是否被成功同步到目标端，可以看到，新增的字段 ext\_column\_0 & ext\_column\_1已经被扩展进目标端，更改的 bigint 字段也完成变更。
+
+![](.topwrite/assets/image_1734677309588.png)
+
+![](.topwrite/assets/image_1734677315955.png)
+
+###
+
+### 实时同步任务的稳定性和指标监控
+
+实时同步和分析链路搭建完成后，最关心的问题之一就是整个链路的稳定性。我们的产品中，为每个多表同步任务提供了完善的监控信息展示，比如同步状态、同步延迟等。面向同步链路里可能会发生的异常情况，比如单条数据写入时发生异常导致任务失败，也提供了任务的自动 Failover 能力，任务失败以后会被自动拉起，减少人为运维处理的投入。
+
+![](.topwrite/assets/image_1734677408156.png)
+
+云器Lakehouse提供了监控告警产品模块，内置了丰富的状态和指标监控能力，支持自定义配置监控规则，来全面监控整个任务运行的状态，包括任务实例运行失败、单表存量数据同步异常、实时同步任务端到端延迟、作业 failover 、源端数据读取的点位延迟等等，一系列的监控事项，都可以通过配置对应的规则给监控起来。
+
+![](.topwrite/assets/image_1734677421992.png)
+
+本次实践演示中，配置了一些监控规则，可以看到下图告警通知，会监控端到端同步的延迟是否超过了 10 秒，在数量特别大时，延迟上去，会被监控捕获到，并通过告警通知提醒负责人感知并及时处理。
+
+![](.topwrite/assets/image_1734677436493.png)
+
+###
+
+### 实时同步任务的运维处置
+
+在实际生产过程中，经常会遇到各种各样的复杂问题，为此云器实时同步方案中也提供了多种配套运维处置功能来进行支持。例如在实时同步运行中，源端数据发生了变化，某个表中的数据出现了问题，针对这种情况，我们提供补数同步功能，支持对特定表重新进行全量同步。在业务突发高峰，源端变更流量非常大时，多个表的变更数据的实时同步会相互影响。这两种情况下，都可以通过全量补数同步的功能去加速数据同步过程。以下图为例，对源端表 yellow\_taxi\_00 表重新进行补数全量同步，其增量实时同步会被暂停，后台会通过全量的方式把源端数据重新同步。补数修订的全量同步完成后，增量同步会自动启动，无需再手动操作。
+
+![](.topwrite/assets/image_1734677453391.png)
+
+此外，云器Lakehouse还为日常运维提供优先执行功能，当在有多张表需要同步，而资源相对有限的条件下，可选择业务上更重要的表优先分配资源，在任务队列里面优先执行该表的数据同步，可以在任务整体出现消费堆积、端到端延迟变大的情况下，也能保证业务关键数据的新鲜度。
+
+![](.topwrite/assets/image_1734677476077.png)
+
+##
+
+## 高性能实时分析
+
+在传统离线数仓架构中，数据经过ETL处理后直接对接BI引擎进行查询，往往响应速度较慢。因此，企业通常会引入如Clickhouse等实时分析引擎来提升查询性能。云器科技的解决方案通过简化这一流程，实现了源端数据的实时写入与目标表的即时查询分析，无需额外的查询加速引擎。
+
+在本次演示中，我们利用Metabase BI工具构建的报表展示了源端MySQL数据行数统计与云器Lakehouse内数据行数的对比，并进行了复杂查询分析，如根据不同乘客数量统计费用的平均值。这一过程中，数据的实时同步写入与查询分析均在同一张表上完成，云器方案在简化架构和提升效率方面优势明显。
+
+![](.topwrite/assets/image_1734677365384.png)
+
+通过产品中提供的“作业历史”产品模块，可以看到提交到Lakehouse引擎的所有 SQL 明细。从下图中可以看到，实时同步写入的是 yellow\_taxi\_demo 表，在Metabase BI 看板里实时查询的也是该表。而且在演示的这个相对复杂的查询条件下，进行了400万行数据的全表扫描，能在 11 毫秒就返回查询结果。云器Lakehouse的方案不需要新增额外的加速引擎来进行查询加速，省去了再同步复制一份数据，所以能够极大地节约整体成本。
+
+![](.topwrite/assets/image_1734677380258.png)
+
+我们接下来看下高并发下的查询响应情况。云器Lakehouse 采用存算分离架构，在查询计算层面，通过不同集群类型来支撑不同的查询负载：
+
+* 通用型集群，面向批处理进行了针对性的优化。
+* 分析型集群，对于在线的实时分查询非常友好。
+
+云器也提供优秀的资源弹性能力，可以设定不同集群规格和弹性伸缩方式，可以配置查询的并发数以及实例的副本个数来实现动态伸缩。比如源端有 8 个并发时，只需要 1 个查询实例，通过弹性设置为 2 个副本，当并发数超过 8 个时，系统会自动拉起扩容出第 2 个副本来承接超过 8 个以上的并发流量，整个过程完全不需要人为干预。
+
+此外，云器Lakehouse还提供自动启停的功能，整个产品的资源收费模型上，在SaaS模式下采取按量付费的模式，比如对于 BI 报表，在夜间没有使用、没有流量时，集群会被自动停止，就会产生费用，能避免资源的空置浪费、节约成本费用。

+# 全增量一体同步功能
+
+全增量一体同步功能是一项强大的数据同步工具，它能够将数据库中的数据完整地同步到Lakehouse中。该功能包括历史数据的全量同步和实时变更数据的增量同步。请注意，此功能目前处于 Beta 版本，部分已知局限将在后续版本中得到改进和优化。
+
+## 任务创建流程
+
+### 操作入口
+
+在任务开发界面，点击新建操作按钮，从下拉菜单中选择“全增量一体同步”任务类型。
+
+![新建全增量一体同步任务](.topwrite/assets/image_1710210458365.png)
+
+### 配置来源数据类型
+
+在创建任务时，首先需要选择一种需要同步的来源数据类型。目前支持的来源数据源类型及对应的增量读取模式和数据库版本如下：
+
+| **类型**     | **增量读取模式** | **数据库版本** |
+| ---------- | ---------- | --------- |
+| MySQL      | Binlog     | 5.x、8.x   |
+| PostgreSQL | WAL 日志     | 14 及以上     |
+
+### 选择同步类型
+
+全增量一体同步任务支持两种同步类型，请根据实际需求进行选择：
+
+1. 实时同步-多表镜像：适用于将源端数据完整地镜像同步到目标端的场景。
+2. 实时同步-多表合并：适用于将分库分表的数据合并后写入同一张目标表的场景。
+
+#### 多表镜像
+
+##### 来源配置
+* 选择数据源：选择一个已有的数据源。如果没有可用的数据源，请参考[数据源配置](config-datasource.md)文档新建一个数据源。
+* 配置读取模式：根据所选数据源类型，选择合适的读取模式。例如，MySQL数据源当前只支持BINLOG模式，而PostgreSQL数据源只支持WALs模式。
+* 选择同步对象：选择需要同步的数据库和表。可以通过批量配置功能，上传配置文件来快速选择多个同步对象。请注意，配置文件中的注释说明需要删除。
+* 配置槽位（slot）
+  * 仅PostgreSQL需要配置，槽位（slot）指PostgreSQL 的 replication slot，详见 [说明文档](https://www.postgresql.org/docs/9.4/catalog-pg-replication-slots.html)。
+  * 每个数据库都需要配置一个槽位。目前支持decoderbufs和pgoutput两种插件类型。
+  * 可以选择已存在的槽位进行使用；或者在页面页面来操作新建，在新建窗口的下方区域的创建语句，可按需修改。点击确定后进行创建。在数据源中配置的用户名必须具备创建slot的权限，否则会创建失败，详见下文的权限说明。
+  * 特别注意，不同任务不要复用同一个槽位。任务启动时，如果槽位被其他正在运行的任务占用，会启动失败。如果其他任务处于停止状态，因槽位中的数据会被共享消费，位点是共享的，新任务消费的增量数据，同步到目标端的表数据可能会不全。
+
+##### **目标配置**
+* 目标数据源：默认选择当前工作空间对应的Lakehouse数据源。
+* 命名空间规则：目前仅支持选择特定的命名空间。未来版本将支持按照源端进行镜像命名或自定义命名规则。
+* 目标表命名规则：目前仅支持镜像来源表名。后续版本将支持添加前缀或自定义命名规则。
+* 计算集群：选择工作空间下可用的计算集群。建议使用AP类型的集群。
+
+##### 预览配置
+在完成源端和目标端配置后，可以预览同步表和字段的映射关系。如有需要修改，可以返回上一步进行调整。
+
+##### 同步规则
+在同步规则中，可以配置Schema Evolution等规则，定义源端表和字段变化后的处理行为。
+
+#### 多表合并
+
+##### **来源配置**
+
+* 选择数据源
+  * 同上，多表镜像同步类似
+* 配置读取模式
+  * 同上，多表镜像同步类似
+* 选择同步对象
+  多表合并同步，会使用“虚拟表”作为中间的过渡承接，需要在配置时指定使用什么虚拟表来承接哪些对象的数据。支持两种方式进行配置
+  * 方式一：基于规则配置，通过正则匹配进行筛选，比如选出以 abc 开头的所有表，在正则表达式中填写 ^abc 即可
+  * 方式二：基于文件批量配置，按照模板中格式要求填写配置文件、上传后，页面会按照文件中给定的内容来选中需要同步的对象，选中后可以按需再进行微调。请注意删除模板文件中的注释说明
+
+##### **目标配置**
+* 同上，和多表镜像同步类似
+
+##### **预览配置**
+* 同上，和多表镜像同步类似
+
+##### **同步规则**
+* 同上，和多表镜像类似
+
+### 配置高级参数
+在任务常规配置完成后，点击“配置”按钮完成高级参数的设置。
+* 集群：指定用于运行同步任务的集群。建议使用AP类型的集群。
+* 更新频率：设定数据写入的频次间隔。
+
+### 提交任务
+点击提交按钮，将任务提交到生产环境执行。请注意，任务提交后默认不启动，需要手动启动。
+
+## 任务运维
+
+### 启动任务
+
+在任务详情页，可以操作启动任务。以下是三种启动方式：
+1. 无状态启动（仅适用于任务首次启动）：完整同步所有数据，先进行全量同步，再启动增量同步。
+2. 从上次保存状态恢复（适用于停止后的任务再次启动）：从停止位置断点续传。
+3. 自定义起始位置：从给定的位点进行同步，可用于数据回刷。对任务中配置的所有表统一生效。
+
+* MySQL：选择指定文件启动或者指定时间启动。在页面监控区域可以获取到上次文件位置。
+* PostgreSQL：指定 LSN 取值，在下文的实例监控中可以查看到最新的 LSN 取值。
+
+### 实例监控
+
+任务启动后，会经历初始化、全量同步、增量同步三个阶段。在实例监控区域，可以查看这三个阶段的运行状态。
+![实例监控](.topwrite/assets/image_1705386710920.png)
+
+### 指标监控
+
+在指标监控区域，可以查看全量同步和增量同步的关键监控指标。
+![指标监控](.topwrite/assets/image_1705386727702.png)
+
+| **指标名称**   | **口径说明**                                               |
+| ---------- | ------------------------------------------------------ |
+| 读取数据       | 数据同步任务在统计周期内从数据源读取的记录数。                                |
+| 写入数据       | 数据同步任务在统计周期内向目标数据源写入的记录数。                              |
+| 平均读取速率     | 数据同步任务在统计周期内平均读取速率。（周期内总读取记录 / 周期时间）                     |
+| 平均写入速率     | 数据同步任务在统计周期内平均写入速率。（周期内总写入记录 / 周期时间）                     |
+| Failover 次数 | 数据同步任务在统计周期内运行发生 Failover 次数。Failover 次数代表数据同步服务自身运行的稳定性。 |
+
+### 同步对象
+
+在同步对象区域，可以查看单表的同步终态和进行对应的运维操作。
+![](.topwrite/assets/image_1710214491047.png)
+
+| **指标** | **口径说明**                                    |
+| ------ | ------------------------------------------- |
+| 最新读取位置 | 同步任务实时读取来源对象数据并写入目标表，以目标表最新一条记录的写入时间作为读取位置。 |
+| 最新更新时间 | 最近一次写入目标表的时间。                               |
+| 数据延迟   | 数据从数据源端事务提交到同步至目标端可见的时间间隔。                  |
+
+| **操作** | **行为定义**                                     |
+| ------ | -------------------------------------------- |
+| 全量同步详情 |                                              |
+| 暂停     | 对于正在同步的表可操作，暂停该表的同步，保存同步位点。                  |
+| 恢复     | 从上次暂停的同步位点开始继续同步。                            |
+| 重新同步   | 对该表重新进行全量和增量同步。                              |
+| 查看异常   | 点击后可以查看表的增量同步任务的异常信息，比如 Schema Evolution 的异常等。 |
+
+### 停止任务
+
+停止任务会停止任务中正在进行的全量同步和增量同步。停止时会自动保存增量同步的位点状态。
+
+* 如果停止时表处在全量同步阶段，重启后，未完全全量同步的表，会重新进行一次全新的全量同步。
+* 如果停止时表处在增量同步阶段，重启后，默认会从同步停止的位点继续同步。
+
+### 下线任务
+
+下线任务属于高危操作，任务下线后，不会保存当前同步的位点。如果再次上线并启动任务，会重新开始同步数据。
+
+* 下线不会清理已经同步到目标端的数据，但会清理中间过程的缓存数据和位点信息。
+* 重新同步不会重新建表，全量数据同步会对于老的表进行覆盖写入，增量同步会对目标表做merge into的更新。
+
+## 权限说明
+
+同步不同类型数据源的变更事件时，需要在相应数据源服务端配置好适当的权限才能保证数据的正常同步。尽管直接分配管理员或超级用户的权限足以保证任务正常运行，但通常希望最小化需要分配给同步数据用户的权限。各操作步骤需要的具体权限配置说明如下。
+
+### PostgreSQL
+
+| 需求                                     | 权限                                                                    | 示例                                                                                                                                                                                   |

+## 已知局限
+
+* 当前方案需要设定数据刷新频次，最少支持设置为 1 分钟。即端到端数据新鲜度延迟至少会在 1 分钟以上，尚未做到秒级延迟（会在后续版本提供）。
+* Schema Evolution，暂不支持变更字段类型、不支持自动新增表。
+* 多表实时同步任务中，源端不同库表中若存在主键相同的数据，同步结果会出现异常。
+* MySQL同步，尚不支持的字段类型：
+

+* **反斜杠序列**：包括`\d`（数字）、`\D`（非数字）、`\s`（空白字符）、`\S`（非空白字符）、`\w`（单词字符）、`\W`（非单词字符）、`\b`（单词边界）和`\B`（非单词边界）。
+* **POSIX通配符**：如`.`（匹配任意单个字符）和`*`（匹配前一个元素的零次或多次出现）。
+* **Unicode支持**：所有正则表达式函数均支持Unicode字符。
+# 转义字符的处理
+在 SQL 语句中使用字符串常量时，如果包含反斜杠序列或元字符（如`\d`、`\s`、`*`、`?`），这些转义字符会被自动转义。例如，`SELECT '\\' AS col;` 的输出将是 `\`。对于表中实际存储的值为 `\\` 的情况，不会发生转义，只有字符串常量会经历这种转义。
+
+因此，当编写需要匹配这些特殊序列的正则表达式时，需要添加额外的转义字符。例如：
+
+```SQL
+-- 在字符串常量中，反斜杠序列会被自动转义
+SELECT '\\\\' as col1, '\\' as col2;
++------+------+
+| col1 | col2 |
++------+------+
+| \\   | \    |
++------+------+
+-- 如果在表中存储的是\\，则不会有自动转义的情况
+CREATE TABLE test_regex(col STRING);
+INSERT INTO test_regex VALUES('\\');
+SELECT * FROM test_regex;
++-----+
+| col |
++-----+
+| \\  |
++-----+
+```
+
+使用正则表达式进行匹配时，需要对含有反斜杠序列或元字符的字符串进行转义：
+
+```SQL
+SELECT col, RLIKE(col, '\\\\') FROM test_regex;
++-----+---------------------+
+| col | RLIKE(col, '\\\\') |
++-----+---------------------+
+| \\  | TRUE                |
++-----+---------------------+
+```
+
+# 字符串前缀 r 的使用
+
+为了避免在不确定何时需要转义的情况下手动处理转义字符，Lakehouse 支持在字符串前添加 `r` 前缀，表示 [字符串](<STRING.md>) 中的转义字符不会被转义，可以直接输入到正则表达式中运行。这样，用户可以像编写普通正则表达式一样，而不必担心 SQL 引擎的转义问题。例如：
+
+```SQL
+-- 使用r前缀与表中的数据进行匹配
+SELECT col, RLIKE(col, r'\\') FROM test_regex;
++-----+---------------------+
+| col | RLIKE(col, '\\\\') |
++-----+---------------------+
+| \\  | TRUE                |
++-----+---------------------+
+-- 使用r前缀匹配字符串常量
+SELECT RLIKE(r'%SystemDrive%\Users\John', r'%SystemDrive%\\Users.*') as res;
++------+
+| res  |
++------+
+| TRUE |
++------+
+--不使用r前缀的正则匹配
+SELECT r'%SystemDrive%\Users\John' rlike '%SystemDrive\\\\\Users.*';
++------+
+| res  |
++------+
+| true |
++------+
+```
+
+通过使用 `r` 前缀，Lakehouse 简化了正则表达式的使用，使得文本匹配和数据处理更加直观和高效。

+# REMOVE 命令
+
+## 概述
+
+REMOVE 命令用于从云器 Lakehouse 的数据湖 Volume 对象中删除文件，同时实际存储与对象存储的文件也会删除。该命令支持在 Studio 和 Lakehouse 客户端中运行。
+
+## 使用场景
+
+* 可以结合Lakehouse定时调度任务将已经导入到lakehouse的文件定时删除
+
+## 语法
+
+```
+REMOVE 
+    [ VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME ]
+    [ SUBDIRECTORY 'dir' | FILE 'file' ] 
+```
+
+## 参数说明
+
+* `VOLUME/TABLE VOLUME/USER VOLUME`：分别指将外部 Volume，TABLE VOLUME 和USER VOLUME 中的数据删除。
+* `SUBDIRECTORY/FILE`：指定下载文件包括的范围，可以是 volume 中的子目录。指定目录会将下面的所有文件删除（`SUBDIRECTORY`），也可以利用 FILE 参数删除多个文件。
+
+## 示例
+
+删除volume中的某个目录
+
+```SQL
+REMOVE VOLUME my_volume SUBDIRECTORY 'delta-format/uploaddelta';
+```

+## 功能概述
+
+**历史版本恢复**：
+使用本命令，您可以将未删除的表或动态表恢复到指定的历史版本。借助时间旅行功能，您可以轻松地将表状态回滚到过去的某个时刻，以便在需要时恢复数据。
+
+**数据保留周期**：
+对象的历史恢复能力取决于数据的保留周期。当前预览版本的数据保留周期默认为7天，未来将调整为1天。您可以通过执行[ALTER命令](TIMETRAVEL.md)来调整保留周期。请注意，修改保留周期可能会增加存储成本。本功能支持表（TABLE）和动态表（DYNAMIC TABLE），不支持物化视图。
+
+## 语法示例
+
+```SQL
+RESTORE TABLE table_name TO time_travel_version;
+time_travel_version ::= 
+    TIMESTAMP AS OF timestamp_expression;
+```
+
+## 参数说明
+
+1. **table\_name**：指定未删除的表名，可以是TABLE、DYNAMIC TABLE或MATERIALIZED VIEW。若表已被删除，请使用[UNDROP](UNDROP-TABLE.md)命令进行恢复。
+2. **time\_travel\_version**：指定要恢复的表版本。先使用 `DESC HISTORY table_name` 查看版本时间点，再通过`TIMESTAMP AS OF`子句来指定具体的时间点。`timestamp_expression` 是一个返回时间戳类型表达式的参数，例如：
+
+* `'2023-11-07 14:49:18'`，即可强制转换为时间戳的字符串。
+* `CAST('2023-11-07 14:49:18' AS TIMESTAMP)`。
+* `CURRENT_TIMESTAMP() - INTERVAL 12 HOURS`：12小时之前的版本。
+* 任何本身是时间戳类型或可强制转换为时间戳的表达式。
+
+## 使用案例
+
+**案例 1：使用 RESTORE 命令恢复普通表到指定版本**
+
+```SQL
+-- 查看表的变更历史
+DESC HISTORY json_table;
+
+-- 使用 RESTORE 命令恢复到指定版本
+RESTORE TABLE json_table TO TIMESTAMP AS OF '2024-01-26 17:44:45.349';
+SELECT * FROM json_table;

+# 了解和使用Result Cache
+
+## 简介
+
+云器 Lakehouse 使用缓存技术来提升查询性能和效率。平台提供了三种类型的缓存来提高查询性能：
+
+1. 查询结果缓存（Result Cache）
+2. 元数据缓存（Metadata Cache）
+3. 虚拟集群本地缓存（Virtual Cluster Local Disk Cache）
+
+    ![](.topwrite/assets/image_1713780513737.png)
+
+其中：
+
+* 元数据缓存和查询结果缓存服务从属于服务层，可在工作空间内共享。
+* 虚拟集群本地缓存保存在集群本地节点，仅在使用指定虚拟集群时才能使用其本地缓存。
+
+本文将介绍查询结果缓存的工作原理及其使用方式。
+
+## 结果缓存
+
+在云器 Lakehouse 中执行查询时，符合一定条件的查询结果会自动保留一段时间，并在该时间段结束后被清除。这部分临时存储的查询结果称为查询结果缓存。
+
+查询结果缓存（Result Cache）需要满足以下条件才能被复用：
+
+* 查询中使用的表的基础数据未发生改变。如果查询中使用的任何表中的数据发生更改，则无法复用结果缓存；
+* 查询中没有包含对视图的引用。如果查询对象中包含视图，则不支持保留查询结果缓存；
+* 新发起的 SQL 查询语句在语法上能够和先前执行过的查询精确匹配；
+* 查询中不包含非确定性函数（例如：CURRENT_TIMESTAMP()）或用户定义函数 (UDF)；
+* 先前的Result Cache未过期删除。
+
+## 结果缓存的过期周期
+
+结果缓存成功后，默认保留周期为24小时。
+
+在 24 小时内，若有后续查询复用了该结果缓存，则其过期时间将额外延长 24 小时。否则，24 小时后，该查询结果缓存将被清除。
+
+## 启用与禁用结果缓存
+
+使用 `cz.sql.enable.shortcut.result.cache` 参数在 SESSION 级别启用或禁用，如下所示。
+
+```Python
+--开启结果缓存
+set cz.sql.enable.shortcut.result.cache=true;
+
+--关闭结果缓存
+set cz.sql.enable.shortcut.result.cache=false;
+```
+
+注：当前（2024 年 04 月）Lakehouse 版本的查询结果缓存（Result Cache）功能处于公测阶段，默认未开启，后续版本将默认开启。
+
+## 约束与限制
+
+缓存保留周期：24小时。
+
+单个工作空间支持缓存的作业数量上限：10万。
+
+结果缓存大小限制：无限制。小于等于10MB的结果将缓存在管控层内存Cache，超过10MB的结果将持久化在存储层（对象存储文件）。
+
+不支持包含非确定性函数、UDF 的查询结果缓存。
+
+## 结果缓存演示
+
+为了演示查询结果缓存，首先启用结果缓存并在云器 Lakehouse 中执行一个 SQL 查询。然后重新运行相同的查询，以验证新查询是否通过重用结果缓存实现了加速。
+
+```Sql
+ --开启结果缓存
+set cz.sql.enable.shortcut.result.cache=true;
+
+ select
+        l_returnflag,
+        l_linestatus,
+        sum(l_quantity) as sum_qty,
+        sum(l_extendedprice) as sum_base_price,
+        sum(l_extendedprice * (1 - l_discount)) as sum_disc_price,
+        sum(l_extendedprice * (1 - l_discount) * (1 + l_tax)) as sum_charge,
+        avg(l_quantity) as avg_qty,
+        avg(l_extendedprice) as avg_price,
+        avg(l_discount) as avg_disc,
+        count(*) as count_order
+from
+        tpch_100g_new.lineitem
+where
+        l_shipdate <= date '1998-12-01' - interval '85' day
+group by
+        l_returnflag,
+        l_linestatus
+order by
+        l_returnflag,
+        l_linestatus
+;
+```
+
+第一次执行花费了12.1秒。通过Job Profile查看作业运行信息，作业从磁盘读取了大量数据。
+
+![](.topwrite/assets/4590d8b1-4fd3-45b6-abd2-816d8ca58242.png)
+
+第二次执行该查询时，作业复用了上次查询的结果缓存，在 15 ms 内返回了结果。
+![](.topwrite/assets/result_cache_query_output.png)
+![](.topwrite/assets/383621f0-27c0-4f17-b217-0c0ad3bbc686.png)
+查看作业的 Job Profile 时，可在诊断页面的执行计划图中看到作业使用了“JOB RESULT REUSE”，说明作业直接查询了结果数据。

+# REVOKE FROM SHARE 语句
+
+## 功能描述
+
+`REVOKE FROM SHARE` 语句用于取消已分享的表（table）或视图（view）的权限。通过执行该语句，可以撤销其他用户或角色对分享对象的访问权限。
+
+仅支持修改类型（kind属性）为'OUTBOUND'（对外分享）的分享对象。其他服务实例分享进入的分享对象（share）不可移除数据对象。
+
+## 语法格式
+
+```SQL
+REVOKE [PERMISSIONS] ON {TABLE table_name | VIEW view_name} FROM SHARE share_name;
+```
+
+**参数说明**
+
+* `PERMISSIONS`：指定要撤销的权限，可选值为 `select`（用于查询数据）和 `read metadata`（用于查看表或视图的元数据）。
+* `TABLE table_name`：指定要撤销权限的表名。
+* `VIEW view_name`：指定要撤销权限的视图名。
+* `share_name`：指定要操作的分享名称。
+
+## 使用示例
+
+1. 撤销用户对分享表的查询权限和元数据查看权限：
+
+   ```SQL
+   REVOKE select, read metadata ON TABLE share_demo_table FROM SHARE share_demo;
+   ```
+
+2. 仅撤销用户对分享视图的查询权限：
+
+   ```SQL
+   REVOKE select ON VIEW share_demo_view FROM SHARE share_demo;
+   ```
+
+3. 撤销用户对分享表的元数据查看权限，但保留查询权限：
+
+   ```SQL
+   REVOKE read metadata ON TABLE share_demo_table FROM SHARE share_demo;
+   ```
+
+## 注意事项
+
+* 执行 `REVOKE FROM SHARE` 语句前，请确保您具有足够的权限来撤销分享对象的权限。
+* 被撤销权限的用户或角色将无法再访问指定的表或视图。
+* 如果需要重新授予权限，可使用 `GRANT` 语句进行操作。
+
+通过以上内容，您可以更好地理解和使用 `REVOKE FROM SHARE` 语句来管理分享对象的权限。

+## RIGHT 函数：从字符串右侧提取指定长度的字符
+
+RIGHT 函数用于从给定字符串的右侧开始提取指定数量的字符。这个函数在处理文本数据时非常有用，尤其是在需要根据特定规则截取字符串的场景下。
+
+### 函数语法
+
+```sql
+RIGHT(string, length)
+```
+
+- `string`：要提取字符的原始字符串。
+- `length`：要提取的字符数量，必须是一个大于或等于零的整数。
+
+### 函数行为说明
+
+- 如果 `length` 等于 0，函数返回一个空字符串。
+- 如果 `length` 大于 `string` 的长度，函数返回 `string` 本身。
+- 如果 `length` 小于 0，函数返回 NULL。
+- 如果 `string` 为 NULL，函数返回 NULL。
+
+### 实际应用案例
+
+**案例 1：提取学生姓名的后两个字符**
+
+假设有一个名为 `student` 的表，其中包含学生的姓名（name）和性别（gender），如下所示：
+
+| id | name  | gender |
+|----|-------|--------|
+| 1  | Alice | F      |
+| 2  | Bob   | M      |
+| 3  | Cathy | F      |
+| 4  | David | M      |
+
+现在，我们想要查询每个学生姓名的后两个字符，可以使用以下 SQL 语句：
+
+```sql
+SELECT name, RIGHT(name, 2) AS suffix FROM student;
+```
+
+查询结果如下：
+
+| name  | suffix |
+|-------|--------|
+| Alice | ce     |
+| Bob   | ob     |
+| Cathy | hy     |
+| David | id     |
+
+**案例 2：提取文件名的扩展名**
+
+假设我们有一个包含文件名的字符串，现在需要提取其扩展名（即文件名中最后一个点号之后的部分）。例如，字符串 `"report.xls"` 的扩展名是 `"xls"`。
+
+```sql
+SELECT RIGHT('report.xls', 4) AS file_extension;
+```
+
+查询结果为：
+
+| file_extension |
+|----------------|
+| xls            |
+
+**案例 3：处理长度不足的情况**
+
+假设我们需要提取字符串末尾的若干字符，但字符串本身的长度可能小于要提取的字符数。例如，处理以下字符串：
+
+- `"这是一个示例文本"`（长度为 9）
+- `"示例"`（长度为 2）
+
+使用 RIGHT 函数提取最后 3 个字符：
+
+```sql
+SELECT RIGHT('这是一个示例文本', 3) AS last_three_chars;
+SELECT RIGHT('示例', 3) AS last_three_chars;
+```
+
+结果如下：
+
+| last_three_chars |
+|------------------|
+| 例文本           |
+| 示例             |

+# 函数名称：RLIKE
+
+## 功能描述
+`RLIKE` 函数用于检查一个字符串是否符合指定的正则表达式模式。它既可以作为操作符使用，也可以作为函数调用，提供灵活的字符串匹配能力。
+
+## 语法
+- 作为操作符使用：
+  ```sql
+  str [NOT] RLIKE regex
+  ```
+- 作为函数使用：
+  ```sql
+  RLIKE(str, regex)
+  ```
+
+## 参数
+- `str`：要检查的字符串。
+- `regex`：用于匹配的正则表达式。
+
+## 返回值
+- 返回布尔值，如果字符串符合正则表达式模式，则返回 `TRUE`；否则返回 `FALSE`。
+- 如果使用 `[NOT] RLIKE` 作为操作符，返回值相反，即不符合模式时返回 `TRUE`。
+
+
+## 使用示例
+
+以下是 RLIKE 函数的使用示例：
+
+1. 匹配字符串开头：
+
+   ```sql
+   select rlike('aabb', r'^a');
+   -- 结果为true，因为字符串'aabb'的开头是'a'
+   ```
+
+2. 匹配字符串开头和结尾：
+
+   ```sql
+   select rlike('aabb', r'^a.*b$');
+   -- 结果为true，因为字符串'aabb'的开头是'a'，结尾是'b'
+   ```
+
+3. 使用通配符匹配任意字符：
+
+   ```sql
+   select rlike('footerbar', r'foo(.*?)(bar)');
+   -- 结果为true，因为正则表达式中的'.*?'可以匹配任意长度的任意字符
+   ```
+
+4. 匹配邮箱地址：
+
+   ```sql
+   select rlike('user@example.com', r'^[a-zA-Z0-9._%-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$');
+   -- 结果为true，因为该正则表达式可以匹配大多数有效的电子邮箱地址
+   ```
+
+5. 匹配电话号码：
+
+   ```sql
+   select rlike('123-4567-8900', r'\d{3}-\d{4}-\d{4}');
+   -- 结果为true，因为该正则表达式可以匹配特定格式的电话号码
+   ```
+6. 使用 NOT RLIKE
+    ```sql
+    -- 使用作为函数
+    SELECT RLIKE('hello world', 'hello.*world') AS result;
+    -- 返回 TRUE
+    
+    -- 使用作为操作符
+    SELECT 'hello world' RLIKE r'hello.*world' AS result;
+    -- 返回 TRUE
+    
+    -- 使用 NOT 操作符
+    SELECT 'hello world' NOT RLIKE r'hello.*world' AS result;
+    -- 返回 FALSE
+    ```

+# 2024年11月12日— 0.9 Lakehouse Platform 产品更新发布说明
+
+本次发布（Release 2024.11.12），我们引入了一系列新功能、增强特性以及修复项。这些更新将分阶段逐步推送至以下区域，预计在发布日起一周至两周内完成。具体时间依据您所在的区域而定。
+
+* 阿里云上海区
+* 腾讯云上海区
+* 腾讯云北京区
+* 腾讯云广州区
+* 亚马逊北京区
+* 国际站-阿里云-新加坡区
+* 国际站-AWS-新加坡区
+
+## 数据湖易用性增强
+
+* **自动Schema探查**：支持对Volume存储中可结构化的文件格式（如csv、parquet、orc文件）自动探查schema，无需预先了解列名和数据类型信息。
+
+* **联邦查询功能拓展**：
+
+  * 新增对Databricks Unity Catalog的联邦查询支持
+  * hive联邦查询：当hive表中是iceberg格式时，支持iceberg格式读取
+
+## 智能化
+
+* **Auto Index**：自动推荐cluster key和sort key，推荐的列可以用来做sort key，挑选的是经常出现在过滤语句中的列。如果将这些列设置为表的sort key，可以加快query的执行速度。
+
+## 增量计算
+
+* **动态表支持DML命令**：支持使用DML命令直接进行数据订正。使用DML修改数据后，下一次刷新将为全量刷新。目前支持INSERT, DELETE, TRUNCATE，暂不支持MERGE INTO, UPDATE。默认情况下，DML修改DT的内容会报错，防止用户误操作。如需操作，请设置`set cz.sql.dt.allow.dml = true;`。
+* **新增分区动态表**：动态分区表通过`SESSION_CONFIGS()['dt.arg.xx']`进行定义，刷新时会增量刷新。 刷新时必须使用显示指定分区的刷新命令`REFRESH DYNAMIC TABLE dt PARTITION partition_spec;`。如果参数使用在普通表，虽然lakehouse没有限制语法但是普通表会全量刷新，刷新语法为`REFRESH DYNAMIC TABLE dt ;`
+
+## SQL能力更新
+
+### 语法支持
+
+* cte语法中支持insert into写到开头。如下案例
+
+```SQL
+--新增语法insert into insert_dest with data as (select 2)select * from data;--之前的语法with data as (select 3) insert into insert_dest with data2 as (select * from data) select * from ddata2
+```
+
+### 函数支持
+
+| 函数名称   | 功能               |
+| ------ | ---------------- |
+| unnest | 函数用于将数组中的元素展开为多行 |
+
+## SDK接口
+
+* JDBC接口新增对vector类型的支持。
+
+## 行为变更
+
+* **增量计算动态表**：在新版本中，如果用户不是简单地删除列/添加列/修改SELECT定义语句，添加列定义只能是从表一路经由SELECT透传的，不能参与任何会影响其他列的计算时则会增量刷新。如果新增的列参与了计算在Create Or Replace发生后，REFRESH任务会退化为一次全量刷新。
+
+* **Quota约束限制**：
+
+  * **Trial账户限制**：单实例下数据对象总数量限制为1000个
+
+* **数据导入**：
+
+  * **Kafka Pipe调整**：将最小间隔从原来的1秒调整为10秒

+# 角色
+
+## 角色（Role）定义
+
+在Lakehouse中，**角色**是一种授权管理的工具，用于将若干个权限点集中在一起，然后再将此角色授予给一个或多个用户（User）。
+
+* 当用户被授予角色后，用户即拥有该角色包含的所有权限。
+* 角色也可被授予更多的权限点，从而实现权限的灵活扩展与管理。
+
+相较于直接对用户逐个授予权限（ACL 模式），通过“角色”来分配权限，可以显著简化管理流程，也更易于维护和审计。因此，推荐在日常的权限管理中，充分使用 **基于角色的访问控制（RBAC，Role-Based Access Control）**。
+
+## 角色类型
+
+Lakehouse中的角色分为两种类型：**预置角色**和**自定义角色**。
+
+1. **预置角色**
+
+   * 预置角色是平台在服务实例创建时自动配置的角色，**不可修改其权限**或**删除**，但可以将预置角色直接授予用户。
+   * 平台预置多个角色，涵盖从实例层面的管理到工作空间层面的管理与使用，帮助用户快速完成基本授权并使用产品功能。全部系统预置角色及其默认权限详见 [系统内置角色权限列表](permissions-of-built-in-workspace-level-roles.md)
+
+2. **自定义角色**
+
+   * 用户可根据自身业务需要，在**工作空间**范围内创建自定义角色，对该角色进行灵活的权限配置与维护。
+   * 自定义角色的权限可随时修改或删除，以便适应不断变化的业务场景需求。
+   * **注意**：目前仅支持在工作空间内创建自定义角色，不支持在实例级别创建自定义角色。创建自定义角色的操作仅支持使用 SQL 执行，暂不支持 Web 端操作。
+
+## 角色级别
+
+大数据平台将元数据对象区分为“**实例级**”和“**工作空间级**”两类，角色也相应分为“**实例角色**”和“**空间角色**”：
+
+**实例角色（Instance Role）**：实例级别角色有两个使用场景：1) 用于实例级资源和操作的全局管控；2) 用于跨多个工作空间的权限授予。
+
+**工作空间角色（Workspace Role）**：作用于特定工作空间范围内的对象（如 schema、table、virtual cluster 等）。工作空间角色以工作空间为边界，互不影响。
+
+## 角色的管理与使用
+
+### 查看角色
+
+可在“管理” > “安全” > “角色”列表中，查看当前实例与工作空间内的角色信息。
+
+或在“管理” > “工作空间”列表中点击进入工作空间详情页，切换到“角色”页签，查看工作空间下的所有角色。
+
+或在SQL中执行以下语句，查询当前连接的工作空间内所有工作空间级别角色：
+
+```
+SHOW ROLES;
+```
+
+### 将角色授予用户
+
+当一个自定义角色创建并具备了相应权限后，需要将该角色授予给用户，用户才能实际使用该角色所包含的权限。
+
+可通过Web端或SQL方式将角色授予用户。
+
+**Web端操作**
+
+在“安全” > “角色”页面，可以查看当前实例下的实例级别角色和工作空间级别角色。
+
+:-: ![](.topwrite/assets/image_1734878372389.png =784)
+
+对任一角色进行授权操作时，点击该角色名称，进入角色详情页，此时可以查看该角色已被授予的所有用户。点击“+ 授予用户”，在弹窗中勾选需要添加的用户，点击“授权”，即可将角色授予用户。
+:-: ![](.topwrite/assets/image_1734878510613.png =798)
+
+要移除已被授予角色的用户时，点击用户名右侧的“...”，选择“移除用户”，即可取消该用户使用这个角色的权限。
+
+在“管理” > “工作空间”列表进入工作空间详情页面，在“角色”页签也可以查看该空间内的角色列表，并通过上述操作将该角色授予或取消授予用户。
+
+:-: ![](.topwrite/assets/image_1734878871234.png =795)
+
+**SQL操作**
+
+仅工作空间级别的用户支持使用 SQL 操作进行授权。在工作空间内执行以下语句，可将空间内角色授予指定用户。
+
+```SQL
+Grant ROLE <ROLE_NAME> TO USER <USER_NAME>;
+```
+
+执行以下语句可移除角色中的指定用户：
+
+```SQL
+REVOKE ROLE <ROLE_NAME> FROM USER <USER_NAME>;
+```
+
+### 创建用户自定义角色
+
+当前仅支持创建工作空间级别的自定义角色，需要使用具备该工作空间管理员（workspace_admin）角色的用户进行操作。仅支持使用 SQL 创建自定义角色。
+
+**创建语法示例**：
+
+```
+CREATE ROLE <ROLE_NAME>;
+```
+
+### 给自定义角色添加权限
+
+在工作空间内，可通过 GRANT 语句为自定义角色添加权限。示例：
+
+```
+-- 授予某自定义角色对 schema my_schema 下所有表的读写权限
+GRANT SELECT, READ METADATA, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA my_schema
+TO ROLE my_custom_role;
+```
+
+## 常见问题
+
+1. **角色和 ACL（访问控制列表）的区别是什么？**
+
+   * ACL 直接将权限授予给用户；而角色将权限“打包”后再授予用户。
+   * 对于部门人员变动频繁或权限配置复杂的场景，建议优先使用角色方式减少重复操作。
+
+2. **是否支持多角色叠加权限？**
+
+   * 支持。一个用户可被授予多个角色，最终生效的权限是各角色权限范围的并集。
+
+3. **实例角色是否可以访问工作空间？**
+
+   * 否。实例角色与工作空间角色互不影响，实例角色不具备也无法获取工作空间级对象的权限。
+
+4. **预置角色能否修改或删除？**
+
+   * 不可以。预置角色是系统内置、不可变动的角色，只能选择是否授予用户。

+# 使用样例数据快速开始查询分析
+
+## 教程概述
+
+通过本教程，您将了解如何利用 Lakehouse 平台内置的样例数据集，无需提前准备数据即可快速使用 SQL 进行查询分析，以评估其功能及性能。
+
+样例数据集由云器平台通过名称为CLICKZETTA\_SAMPLE\_DATA的数据集以共享方式开放给所有账户查询。本教程将以其中的 TPC-H 100GB 数据集为例，介绍如何在 Lakehouse 中快速完成 TPC-H 测试集的查询测试，评估处理性能。
+
+本教程将按以下步骤进行：
+
+* 环境准备：通过样例数据集检查原始数据，创建测试使用的计算集群
+* 发起查询：使用 Studio Web 环境创建 SQL 查询，完成 22 个 TPC-H SQL 查询
+* 变更集群大小：调整集群大小，扩大至之前集群大小的 4 倍
+* 发起查询：使用调整大小后的集群再次完成 22 个 TPC-H SQL 查询
+* 观察不同集群规格下，查询时延的变化
+
+## Step01. 准备工作
+
+首先，登录 Lakehouse Web 控制台并进入指定的工作空间后，可访问“数据”模块，检查数据管理下的数据对象列表中“clickzetta_sample_data.tpch_100gb”下的相关表是否存在。
+![](.topwrite/assets/image_1716285499384.png)
+
+其次，我们将为本次测试临时创建一个独立的计算集群用于查询分析。您可以通过访问 Lakehouse Web 控制台的“计算 → 集群”菜单，通过页面向导新建集群。
+![](.topwrite/assets/tpch_100g_vc.png)
+
+同时，您也可以通过 SQL 命令来创建集群。使用 SQL 命令操作时，您可以在不离开 SQL 开发上下文的情况下，在 Ad-hoc 或 ETL 开发过程中通过 SQL 命令控制集群的创建、扩/缩容、暂停/恢复、销毁等操作，这通常可以提高计算资源的操作效率。
+
+本教程中，通过在“开发”模块新建 SQL 脚本任务并执行以下脚本，即可快速创建集群。
+![](.topwrite/assets/image_1716953675576.png)
+
+```sql
+-- 创建分析型虚拟计算资源
+create vcluster if not exists TPCH_100GB vcluster_size='Medium' vcluster_type='Analytics'  AUTO_RESUME=TRUE AUTO_SUSPEND_IN_SECOND=300 min_replicas=1 max_replicas=1 comment 'TPCH 100GB TEST';
+```
+
+> 注：计算集群的 vcluster_size 参数同时支持以 T-shirt size（XSMALL、SMALL、LARGE 等）和以数字（1, 2, 4, 16 等）表达的方式，以提供更丰富的计算集群规格，满足不同场景的需要。更多信息详见：[计算集群规格代码变更说明](vcluster_size_description.md)
+
+^
+
+## Step02. 对样例数据进行TPC-H的查询
+
+在“开发”模块新建 SQL 脚本任务，录入 TPC-H 的 22 个查询语句，在“集群”下拉列表中选择刚才创建的测试集群，然后选中任务中的全部脚本并点击“运行”按钮进行串行查询。
+![](.topwrite/assets/image_1716953736183.png)
+
+查询脚本为：
+
+```sql
+-- 执行使用TPCH_100GB计算资源运行作业
+use vcluster TPCH_100GB;
+
+-- 设置查询的标签
+set query_tag='tpch100g_benchmark';
+
+-- Q1

+
+如果您希望进行性能测试，可连续执行2次以上的查询，以便计算集群能够充分Cache数据发挥最佳性能。同时，云器 Lakehouse 也提供了系统主动缓存（Cache）功能，本教程暂不展开这部分介绍。以下是第二次运行时，计算集群缓存（Cache）数据后的运行结果，较第一次无缓存时性能有明显提升。
+![](.topwrite/assets/image_1716954084738.png)
+
+如果希望查看 22 个查询中每个查询的执行详情，可通过访问“计算 → 作业历史”，根据查询标签“tpch100g_benchmark”对查询历史进行过滤后查看。
+![](.topwrite/assets/image_1716285600039.png)
+
+## Step03. 扩大集群规格，再次对样例数据进行 TPC-H 的查询
+
+通过“计算 → 集群”管理页面，您可以修改刚才创建的测试集群的规格大小，例如从 M 修改为 L，L 规格是 M 规格的 2 倍。
+![](.topwrite/assets/tpch_vc_edit_to_L.png)
+
+或者在SQL脚本中执行以下命令进行修改：
+
+```sql
+-- 修改集群大小
+alter vcluster TPCH_100GB SET VCLUSTER_SIZE = 'LARGE';
+```
+
+修改后，使用调整大小后的集群再次进行查询测试。
+![](.topwrite/assets/image_1716954399887.png)
+新扩容的计算节点在数据被充分缓存（Cache）后，性能会继续提升。
+![](.topwrite/assets/image_1716954453780.png)
+![](.topwrite/assets/image_1716954471528.png)
+
+通过作业的运行时间可以观察到，在相同的数据规模和查询任务下，扩大计算集群规格后，任务的总体运行时间大幅缩短。在两次执行后，随着数据被缓存，查询性能得到进一步提升。

+# 云器Lakehouse安全功能概览
+
+云器Lakehouse致力于为客户打造一个安全可靠的云上环境，确保客户的账户、信息、业务和数据得到企业级的安全保障。为了实现这一目标，云器Lakehouse采用了多层次的安全措施，涵盖了架构安全、网络安全、访问控制、审计与监控以及数据加密等方面。以下是对这些安全功能的详细解析。
+
+## 1. 架构安全和多租户隔离
+
+云器Lakehouse在公有云环境中部署，采用高可用性架构，确保服务的稳定性和可靠性。通过使用多副本冗余存储和多种防护技术（如主机安全、WAF、抗DDOS等），保障服务架构和基础设施的安全。
+
+为了实现不同租户之间的数据和计算资源隔离，云器Lakehouse在数据传输层进行数据完整性和正确性校验，确保数据的完整性和防篡改性。
+
+![](.topwrite/assets/安全体系.png)
+
+## 2. 网络安全
+
+云器Lakehouse支持SSL/TLS加密传输，确保数据在传输过程中的安全性。租户可以通过设置IP白名单策略，控制可访问其Lakehouse服务实例的网络地址范围。例如，租户可以将公司内部的IP地址添加到白名单中，以仅允许来自这些地址的访问。
+
+## 3. 访问控制
+
+云器Lakehouse通过工作空间实现对数据和计算资源的进一步隔离。只有加入工作空间的用户才能访问其中的数据和计算资源。此外，云器Lakehouse提供ACL（访问控制列表）和RBAC（基于角色的访问控制）两种授权方式，允许用户根据业务需求自定义角色，并进行表级别粒度的授权。
+
+例如，管理员可以为数据分析师创建一个工作空间，并为其分配相应的角色和权限，以便他们能够访问和处理特定的数据表。
+
+## 4. 审计与监控
+
+云器Lakehouse记录了对数据的所有操作，这些历史记录为只读且不可编辑，保存时间长达6个月。同时，平台提供监控和报警功能，帮助用户及时感知作业异常、数据异常等情况，并根据报警的严重程度发送通知。
+
+例如，当某个作业执行失败时，系统会自动发送报警通知给管理员，以便其能够及时采取措施解决问题。
+
+## 5. 数据加密
+
+云器Lakehouse对敏感数据（如账户信息）进行加密存储，确保数据在整个生命周期中的安全性。用户可以通过配置数据加密功能来进一步保护数据。当数据加密功能启用后，数据将在写入Lakehouse后的全生命周期内保持加密存储，仅在租户专属的计算节点处理数据时进行解密。
+
+例如，当企业需要存储和处理涉及个人隐私的数据时，可以启用数据加密功能，以确保数据的安全性。
+
+## 6. 数据容灾与恢复
+
+云器Lakehouse依托云服务商IaaS层的存储服务，基于多副本、高可用的云基础设施搭建，具备极高的服务可用性和数据可靠性。此外，平台默认提供1天的数据恢复功能，有效降低数据误删除、误修改风险，加强对数据完整性的保护。
+
+例如，在发生数据误删除的情况下，用户可以通过time travel功能恢复数据至7天内的任意状态，从而避免数据丢失的风险。
+
+综上所述，云器Lakehouse通过多层次的安全措施，为用户提供了一个安全可靠的云上环境。用户可以根据自身需求和场景，灵活地配置和使用这些安全功能，以确保业务和数据的安全。

+
+## 语法
+
+```SQL
+SELECT <expr> FROM external_catalog_name.schema_name.table_name;
+```
+
+### 参数说明
+
+* `<expr>`：用户希望查询的字段或表达式。
+* `external_catalog_name`：外部目录的名称。
+* `schema_name`：模式名称，用于组织数据库对象。
+* `table_name`：表的名称，用户希望查询的数据集。
+  **注意事项**
+查询 External Catalog 下的表必须使用三层结构语法。
+
+## 示例
+
+```SQL
+SELECT * FROM my_external_catalog.my_schema.my_table;
+```

+# 语义视图（Semantic View）
+
+## 概述
+
+语义视图是云器 Lakehouse 中的一种架构级逻辑数据模型对象，用于弥合业务用户描述数据的方式与数据在数据平台中实际存储方式之间的差距。
+
+如果没有语义视图，不同的报表和应用中可能存在不一致的计算方式，导致偏差结果。语义视图作为面向业务的抽象层，解决了以下常见问题：
+
+* **对于数据分析**：语义视图提供了统一的指标和维度定义，使业务用户无需编写复杂的 JOIN 语句即可查询跨表数据，显著降低了 SQL 编写门槛。
+* **对于数据治理**：语义视图以声明式方式集中管理表关系、维度和指标的定义，确保组织内部所有利益相关方——从数据分析师到业务用户——使用的都是相同的数据口径。
+
+***
+
+## 语义视图中的概念
+
+语义视图由以下核心组件构成：
+
+**逻辑表（TABLES**）：在语义视图中，您定义的逻辑表通常对应业务实体，如客户、订单或商品明细。每个逻辑表映射到一张物理表，并通过主键和外键声明表间关系。您可以通过外键定义逻辑表之间的连接关系，从而实现跨实体的数据分析——就像在数据库中连接物理表一样，但无需在查询时手动编写 JOIN。
+
+**维度（DIMENSIONS**）：维度是分类属性，为指标提供上下文含义。它们通过将数据分组为有意义的类别来回答"谁"、"什么"、"哪里"和"何时"等问题，例如订单日期、客户名称或订单年份。
+
+**指标（METRICS**）：指标是通过对列进行聚合计算（如 `SUM`、`AVG`、`COUNT`）得出的量化业务度量。它们将原始数据转化为有意义的业务指标，例如"客户总数"或"平均订单价值"。指标代表了报表和仪表盘中驱动业务决策的 KPI。
+
+**过滤器（FILTERS**）：过滤器是预定义的、可重用的过滤条件，用于在语义视图中封装常用的业务筛选逻辑。
+
+***
+
+## 创建语义视图
+
+### 语法
+
+```sql
+CREATE SEMANTIC VIEW <视图名称>
+TABLES (
+    <逻辑表定义> [ , ... ]
+)
+[ FILTERS (
+    <过滤器定义> [ , ... ]
+) ]
+DIMENSIONS (
+    <维度定义> [ , ... ]
+)
+METRICS (
+    <指标定义> [ , ... ]
+)
+[ COMMENT = '<视图说明>' ]
+;
+```
+
+其中，各子句的定义语法如下：
+
+#### 逻辑表定义
+
+```sql
+<表别名> AS <架构名>.<物理表名>
+    PRIMARY KEY ( <列名> [ , ... ] )
+    [ FOREIGN KEY ( <列名> ) REFERENCES <其他逻辑表别名> ]
+    [ WITH SYNONYMS ( '<同义词>' [ , ... ] ) ]
+    [ COMMENT = '<说明>' ]
+```
+
+#### 过滤器定义
+
+```sql
+<逻辑表别名>.<过滤器名> AS <布尔表达式>
+```
+
+#### 维度定义
+
+```sql
+{ <逻辑表别名>.<维度名> | <维度名> } AS <表达式>
+    [ WITH SYNONYMS = ( '<同义词>' [ , ... ] ) ]
+    [ is_unique = { true | false } ]
+    [ is_time = { true | false } ]
+    [ enum_values = [ <值1>, <值2>, ... ] ]
+    [ COMMENT = '<说明>' ]
+```
+
+#### 指标定义
+
+```sql
+<逻辑表别名>.<指标名> AS <聚合表达式>
+    [ COMMENT = '<说明>' ]
+```
+
+### 参数说明
+
+**逻辑表定义参数**：
+
+| 参数                                          | 说明                                                                  |
+| ------------------------------------------- | ------------------------------------------------------------------- |
+| `<表别名> AS <架构名>.<物理表名>`                     | 为物理表指定一个逻辑别名。在后续的外键引用、维度和指标定义中，均使用此别名来引用逻辑表                         |
+| `PRIMARY KEY ( <列名> [ , ... ] )`            | 指定逻辑表中作为主键的一列或多列。主键有助于确定表之间的关系类型（如一对多或一对一）                          |
+| `FOREIGN KEY ( <列名> ) REFERENCES <其他逻辑表别名>` | 定义当前逻辑表与另一个逻辑表之间的外键关系。引用目标必须使用逻辑表别名（而非物理表名）。语义视图在查询时会根据此外键关系自动处理表连接 |
+| `WITH SYNONYMS ( '<同义词>' )`                 | 为逻辑表定义同义词，增强可发现性                                                    |
+| `COMMENT = '<说明>'`                          | 为逻辑表添加描述性注释                                                         |
+
+**维度定义参数**：
+
+| 参数                                       | 说明                                             |
+| ---------------------------------------- | ---------------------------------------------- |
+| `is_unique`                              | 标识该维度的值是否唯一。当设置为 `true` 时，表示该维度列中不包含重复值，例如客户名称 |
+| `is_time`                                | 标识该维度是否为时间类型。当设置为 `true` 时，表示该维度代表时间属性，例如订单日期  |
+| `enum_values`                            | 定义该维度允许的枚举值列表。这有助于约束维度的取值范围并提升查询准确性            |
+| `WITH SYNONYMS = ( '<同义词1>', '<同义词2>' )` | 为维度定义一个或多个同义词，使用户可以使用不同的业务术语来引用同一个维度           |
+
+**指标聚合函数**： `COUNT`、`AVG`、`SUM`、`MIN`、`MAX`
+
+### 使用说明
+
+* 在语义视图中，您必须至少定义一个维度或一个指标，即必须包含 `DIMENSIONS` 子句或 `METRICS` 子句。
+* 在 `TABLES` 子句中，被外键引用的逻辑表必须先于引用它的表进行定义。例如，如果 `orders` 表的外键引用了 `customers` 表，则 `customers` 的定义必须出现在 `orders` 之前，或至少在同一 `TABLES` 子句中已被声明。
+* 如果目标语义视图已存在，`CREATE SEMANTIC VIEW` 将报错。建议使用 `DROP SEMANTIC VIEW IF EXISTS` 语句先删除已有视图，以确保脚本的幂等性（可重复执行）。
+* 维度和指标支持两种命名方式：**限定名称**（`<逻辑表别名>.<名称>`，如 `orders.order_date`）和**短名称**（直接使用名称，如 `order_date`）。当维度或指标名称在语义视图中唯一时，可以使用短名称；如果存在同名冲突，则必须使用限定名称。
+* 维度支持将表达式作为定义，即**计算维度**。例如，`YEAR(o_orderdate)` 可从订单日期中提取年份，作为一个独立的维度使用。
+
+### 示例
+
+以下示例使用 TPC-H 数据集创建一个名为 `tpch_rev_analysis` 的语义视图，用于收入分析场景。该数据集包含客户、订单和订单明细等表，代表了一个简化的业务场景。
+
+该语义视图定义了：
+
+* 三个逻辑表（`orders`、`customers` 和 `line_items`），分别映射到 TPC-H 中的订单表、客户表和订单明细表。
+* `orders` 和 `customers` 之间的外键关系（通过 `o_custkey`）。
+* `line_items` 和 `orders` 之间的外键关系（通过 `l_orderkey`）。
+* 用于分组和过滤的维度：客户名称、订单日期和订单年份。
+* 量化的业务指标：客户总数和平均订单价值。
+
+#### 基础语义视图
+
+```sql
+DROP SEMANTIC VIEW IF EXISTS tpch_rev_analysis;
+CREATE SEMANTIC VIEW tpch_rev_analysis
+TABLES (
+    customers AS TPCH_SF1.CUSTOMER
+        PRIMARY KEY (c_custkey)
+        COMMENT = 'Main table for customer data',
+    orders AS TPCH_SF1.ORDERS
+        PRIMARY KEY (o_orderkey)
+        FOREIGN KEY (o_custkey) REFERENCES customers
+        WITH SYNONYMS ('sales orders')
+        COMMENT = 'All orders table for the sales domain',
+    line_items AS TPCH_SF1.LINEITEM
+        PRIMARY KEY (l_orderkey, l_linenumber)
+        FOREIGN KEY (l_orderkey) REFERENCES orders
+        COMMENT = 'Line items in orders'
+)
+DIMENSIONS (
+    customers.customer_name AS customers.c_name
+        WITH SYNONYMS = ('customer name')
+        COMMENT = 'Name of the customer',
+    orders.order_date AS o_orderdate
+        COMMENT = 'Date when the order was placed',
+    orders.order_year AS YEAR(o_orderdate)
+        COMMENT = 'Year when the order was placed'
+)
+METRICS (
+    customers.customer_count AS COUNT(c_custkey)
+        COMMENT = 'Count of number of customers',
+    orders.order_average_value AS AVG(orders.o_totalprice)
+        COMMENT = 'Average order value across all orders'
+)
+COMMENT = 'Semantic view for revenue analysis';
+```
+
+在上述示例中，`TABLES` 子句定义了三个逻辑表：一个包含 TPC-H 订单信息的 `orders` 表，一个包含客户信息的 `customers` 表，以及一个包含订单明细的 `line_items` 表。每个逻辑表通过 `PRIMARY KEY` 子句标识主键列，并通过 `FOREIGN KEY ... REFERENCES` 子句声明与其他逻辑表的关联关系。同义词和注释使逻辑表更易于被发现和理解。
+
+`DIMENSIONS` 子句定义了三个维度：`customer_name` 直接映射到客户表的 `c_name` 列；`order_date` 映射到订单日期列；`order_year` 是一个计算维度，通过 `YEAR()` 函数从订单日期中提取年份。
+
+`METRICS` 子句定义了两个指标：`customer_count` 使用 `COUNT` 聚合函数统计客户数量；`order_average_value` 使用 `AVG` 聚合函数计算平均订单价值。
+
+#### 带过滤器和维度元数据的语义视图
+
+以下示例在基础版本上增加了过滤器、维度唯一性标识、时间类型标识和枚举值约束，展示了语义视图的高级特性：
+
+```sql
+DROP SEMANTIC VIEW IF EXISTS tpch_rev_analysis;
+CREATE SEMANTIC VIEW tpch_rev_analysis
+TABLES (
+    customers AS TPCH_AI.CUSTOMER
+        PRIMARY KEY (c_custkey)
+        COMMENT = 'Main table for customer data',
+    orders AS TPCH_AI.ORDERS
+        PRIMARY KEY (o_orderkey)
+        FOREIGN KEY (o_custkey) REFERENCES customers
+        WITH SYNONYMS ('orders_synonyms')
+        COMMENT = 'All orders table for the sales domain',
+    line_items AS TPCH_AI.LINEITEM
+        PRIMARY KEY (l_orderkey, l_linenumber)
+        FOREIGN KEY (l_orderkey) REFERENCES orders
+        COMMENT = 'Line items in orders'
+)
+FILTERS (
+    customers.is_ny AS customers.c_city = 'New York'
+)
+DIMENSIONS (
+    customers.customer_name AS customers.c_name
+        WITH SYNONYMS = ('customer name', 'dimensions_synonyms')
+        is_unique = true
+        COMMENT = 'Name of the customer',
+    orders.order_date AS o_orderdate
+        is_time = true
+        enum_values = [date'2025-01-01', date'2025-06-01', date'2025-12-01']
+        COMMENT = 'Date when the order was placed',
+    orders.order_year AS YEAR(o_orderdate)
+        COMMENT = 'Year when the order was placed'
+)
+METRICS (
+    customers.customer_count AS COUNT(c_custkey)
+        COMMENT = 'Count of number of customers',
+    orders.order_average_value AS AVG(orders.o_totalprice)
+        COMMENT = 'Average order value across all orders'
+)
+COMMENT = 'Semantic view for revenue analysis';
+```
+
+在此示例中，`FILTERS` 子句定义了一个名为 `is_ny` 的过滤器，用于筛选城市为"New York"的客户记录。该过滤器封装了一个可重用的业务筛选条件，避免在多处查询中重复编写相同的 `WHERE` 子句。
+
+`customer_name` 维度设置了 `is_unique = true`，表示客户名称在数据集中是唯一的。`order_date` 维度设置了 `is_time = true`，表示该字段为时间属性，同时通过 `enum_values` 限定了该维度的允许取值为三个特定日期。
+
+> **注意**：`FILTERS` 子句中定义的命名过滤器（如 `is_ny`）是面向 AI/元数据层的语义注解，不能作为 `semantic_view()` 函数的参数直接传入。若要在查询中应用过滤条件，需将对应列定义为 `DIMENSION`，再通过外层 `WHERE` 子句实现过滤。
+
+***
+
+## 查询语义视图
+
+### 语法
+
+使用 `semantic_view()` 表函数在 `SELECT` 语句中查询语义视图：
+
+```sql
+SELECT *
+FROM semantic_view(
+    <视图名称>,
+    DIMENSIONS <维度名> [ , DIMENSIONS <维度名> ... ],
+    METRICS <指标名> [ , METRICS <指标名> ... ]
+);
+```
+
+在查询中，您可以使用限定名称（`<逻辑表别名>.<名称>`）或短名称（直接使用名称）来引用维度和指标。当名称在语义视图中唯一时，两种方式等效，返回相同的结果。
+
+### 使用说明
+
+* 查询结果会按指定的维度自动分组，并根据指标定义中的聚合函数计算指标值。语义视图引擎会根据 `TABLES` 子句中定义的外键关系自动处理所需的表连接，用户无需手动编写 JOIN 逻辑。
+* 维度在结果中的排列顺序与查询中指定的顺序一致。
+
+### 示例
+
+#### 使用限定名称查询单维度和单指标
+
+以下查询返回按订单日期分组的平均订单价值：
+
+```sql
+SELECT * FROM semantic_view(
+    tpch_rev_analysis,
+    DIMENSIONS orders.order_date,
+    METRICS orders.order_average_value
+);
+```
+
+输出示例：
+
+```
+2021-01-01    125.000000
+```
+
+#### 使用限定名称查询多维度
+
+以下查询按订单日期和客户名称两个维度分组，返回平均订单价值：
+
+```sql
+SELECT * FROM semantic_view(
+    tpch_rev_analysis,
+    DIMENSIONS orders.order_date,
+    DIMENSIONS customers.customer_name,
+    METRICS orders.order_average_value
+);
+```
+
+输出示例：
+
+```
+2021-01-01    Join    125.000000
+```
+
+#### 使用短名称查询
+
+当维度和指标名称在语义视图中唯一时，可以省略逻辑表别名前缀，直接使用短名称。以下查询与上一个示例等效：
+
+```sql
+SELECT * FROM semantic_view(
+    tpch_rev_analysis,
+    DIMENSIONS order_date,
+    DIMENSIONS customer_name,
+    METRICS order_average_value
+);
+```
+
+#### 使用 WHERE 子句过滤数据
+
+将需要过滤的列定义为维度后，可通过外层 `WHERE` 子句实现数据筛选（对应 `FILTERS` 中的命名条件）：
+
+```sql
+SELECT * FROM semantic_view(
+    tpch_rev_analysis,
+    DIMENSIONS customers.customer_city,
+    DIMENSIONS customers.customer_name,
+    METRICS orders.order_average_value
+) WHERE customer_city = 'New York';
+```
+
+### 传统 SQL 查询对比
+
+为了说明语义视图如何简化查询，以下对比展示了同一分析需求分别使用传统 SQL 和语义视图的写法。
+
+**传统 SQL 查询**：
+
+使用传统方式，您需要手动编写 JOIN 逻辑、指定连接条件，并显式声明 GROUP BY 子句：
+
+```sql
+SELECT
+    o.o_orderdate,
+    c.c_name,
+    AVG(o.o_totalprice) AS avg_value
+FROM TPCH_SF1.ORDERS o
+JOIN TPCH_SF1.CUSTOMER c ON o.o_custkey = c.c_custkey
+GROUP BY o.o_orderdate, c.c_name;
+```
+
+**语义视图查询**：
+
+使用语义视图时，您只需指定所需的维度和指标，语义视图引擎会自动根据预定义的表关系处理连接和聚合：
+
+```sql
+SELECT * FROM semantic_view(
+    tpch_rev_analysis,
+    DIMENSIONS order_date,
+    DIMENSIONS customer_name,
+    METRICS order_average_value
+);
+```
+
+语义视图查询具有以下优势：
+
+* **无需编写 JOIN 逻辑**：表连接由语义视图引擎根据外键定义自动完成。
+* **使用业务术语**：如 `customer_name`、`order_average_value` 代替物理列名，提升可读性。
+* **查询语法极大简化**：降低了非技术用户的使用门槛。
+* **指标定义集中管理**：确保了整个组织内度量计算的一致性。
+
+***
+
+## 管理语义视图
+
+### DROP SEMANTIC VIEW
+
+删除指定的语义视图。`IF EXISTS` 子句可防止在视图不存在时报错。
+
+**语法**：
+
+```sql
+DROP SEMANTIC VIEW IF EXISTS <视图名称>;
+```
+
+**示例**：
+
+```sql
+DROP SEMANTIC VIEW IF EXISTS tpch_rev_analysis;
+```
+
+### SHOW SEMANTIC VIEWS
+
+列出当前架构中所有可用的语义视图。
+
+**语法**：
+
+```sql
+SHOW SEMANTIC VIEWS;
+-- 或指定架构
+SHOW SEMANTIC VIEWS IN <架构名>;
+```
+
+该命令返回语义视图所在的架构名称和视图名称，方便您查看当前环境中已创建的全部语义视图。
+
+### DESC EXTENDED
+
+查看指定语义视图的详细定义信息，包括逻辑表结构、维度元数据、指标定义、外键关系及索引信息。
+
+**语法**：
+
+```sql
+DESC EXTENDED <视图名称>;
+```
+
+**示例**：
+
+```sql
+DESC EXTENDED tpch_rev_analysis;
+```
+
+返回内容涵盖：逻辑表信息（物理表映射、主键和外键）、维度元数据（`isUnique`、`enumValues` 等属性）、指标定义（聚合表达式）以及索引信息（如 `BLOOM_FILTER`）。
+
+### 相关命令速查
+
+| 命令                             | 说明       |
+| ------------------------------ | -------- |
+| `CREATE SEMANTIC VIEW`         | 创建语义视图   |
+| `DROP SEMANTIC VIEW IF EXISTS` | 删除语义视图   |
+| `SHOW SEMANTIC VIEWS`          | 列出所有语义视图 |
+| `DESC EXTENDED`                | 查看语义视图详情 |
+| `semantic_view()`              | 查询语义视图   |
+
+***
+
+## 最佳实践
+
+**使用 DROP IF EXISTS 确保幂等性**：在创建语义视图之前，始终先执行 `DROP SEMANTIC VIEW IF EXISTS` 语句。这确保了您的脚本在任何环境中都可以重复执行，而不会因视图已存在而失败。
+
+```sql
+DROP SEMANTIC VIEW IF EXISTS tpch_rev_analysis;
+CREATE SEMANTIC VIEW tpch_rev_analysis
+    ...
+```
+
+**从小规模开始，逐步扩展**：建议从一个聚焦的分析场景开始（例如 3–5 张表的收入分析），验证维度和指标的定义准确性后，再逐步扩展到更多表和更复杂的业务逻辑。
+
+**使用有意义的业务术语命名**：为逻辑表、维度和指标选择与业务用户日常用语一致的名称。例如，使用 `customer_name` 而非 `c_name`，使用 `order_average_value` 而非 `avg_o_totalprice`。同时，善用 `WITH SYNONYMS` 和 `COMMENT` 增强语义视图的可发现性和可理解性。
+
+**合理定义维度元数据**：正确设置 `is_unique`、`is_time` 和 `enum_values` 等属性，帮助查询引擎优化执行计划，并为下游工具和用户提供更丰富的上下文信息。
+
+**注意逻辑表的定义顺序**：在 `TABLES` 子句中，被外键引用的逻辑表必须先于引用方定义。合理规划表的声明顺序可以避免创建时的引用错误。

+## 功能
+`SHOW CACHED STATUS`命令用于查看当前数据库中被缓存的表状态。需要注意的是，此命令仅能显示通过`CACHE`命令手动添加到缓存中的表，而无法显示系统自动缓存的表。
+
+## 语法
+```
+SHOW CACHED STATUS;
+```
+
+## 说明
+- 使用`SHOW CACHED STATUS`命令后，将列出所有正在被缓存的表及其相关信息。
+- 该命令不会显示因系统自动缓存机制而缓存的表，仅展示用户通过`CACHE`命令显式添加的表。
+
+## 示例
+```
+-- 将tpch100g分区表part和nation添加到缓存中
+CACHE TABLE tpch100g.part, nation;
+
+-- 查看当前缓存的表状态
+SHOW CACHED STATUS;
+```
+
+执行上述命令后，将显示类似于以下的结果：
+```
++----------------+--------+-------+
+| Table           | Refs   | Cache |
++----------------+--------+-------+
+| tpch100g.part  | 10     | YES   |
+| tpch100g.nation| 5      | YES   |
++----------------+--------+-------+
+```
+
+在此结果中，`Table`列显示表的名称，`Refs`列显示表的引用次数，`Cache`列显示表是否正在被缓存。

+## 概述
+
+`SHOW COLUMNS` 是一种用于查看表中列信息的 SQL 命令。通过该命令，用户可以快速获取表的列名、数据类型等详细信息。
+
+## 语法结构
+```sql
+SHOW COLUMNS
+[ IN | FROM ]                 -- 使用 IN 或 FROM 关键字
+[<schema_name>.]<table_name>  -- 带可选 Schema 前缀的表名
+[IN <schema_name>]            -- 表名与 Schema 分离写法
+```
+
+## 参数详解
+
+### 核心参数
+| 参数格式                     | 是否必须 | 说明                                                                 |
+|----------------------------|---------|--------------------------------------------------------------------|
+| `<table_name>`             | 必需    | 目标表名称                                                          |
+| `<schema_name>`            | 可选    | Schema 名称，支持两种指定方式：<br>1. 作为表名前缀 `schema.table`<br>2. 通过 `IN` 子句指定 |
+
+## 使用规范
+### 路径指定方式（二选一）
+```sql
+-- 方式1：Schema 与表名合并写法
+SHOW COLUMNS IN sales.orders;
+
+-- 方式2：Schema 与表名分离写法
+SHOW COLUMNS FROM orders IN sales;
+```
+
+### 禁止用法示例
+```sql
+-- 错误！重复指定 Schema
+SHOW COLUMNS IN sales.orders IN sales;
+
+-- 错误！混合使用两种语法
+SHOW COLUMNS FROM sales.orders IN production;
+```
+
+
+## 使用示例
+
+查看当前模式下的表列信息：
+
+```sql
+SHOW COLUMNS IN household_demographics;
++-------------+------------------------+-------------------+-----------+---------+
+| schema_name |       table_name       |    column_name    | data_type | comment |
++-------------+------------------------+-------------------+-----------+---------+
+| tpcds_10tb  | household_demographics | hd_demo_sk        | int       |         |
+| tpcds_10tb  | household_demographics | hd_income_band_sk | int       |         |
+| tpcds_10tb  | household_demographics | hd_buy_potential  | string    |         |
+| tpcds_10tb  | household_demographics | hd_dep_count      | int       |         |
+| tpcds_10tb  | household_demographics | hd_vehicle_count  | int       |         |
++-------------+------------------------+-------------------+-----------+---------+
+```
+
+## 常见问题
+
+Q1：如何查看表的详细信息（如表结构）？
+
+* 使用 `DESCRIBE` 或 `SHOW CREATE TABLE` 命令：
+  ```sql
+  DESCRIBE public.household_demographics;
+  SHOW CREATE TABLE public.household_demographics;
+  ```
+
+Q2：`SHOW COLUMNS` 是否支持过滤条件？
+
+* 不支持直接过滤，但可以通过查询 `INFORMATION_SCHEMA.COLUMNS` 实现：
+  ```sql
+  SELECT * FROM INFORMATION_SCHEMA.COLUMNS
+  WHERE TABLE_NAME = 'household_demographics' AND COLUMN_NAME LIKE 'name%';
+  ```

+## 功能概述
+
+`SHOW SCHEMAS` 语句旨在展示当前工作空间（WORKSPACE）中所有模式（SCHEMA）的列表。用户可以通过灵活的过滤条件，根据特定的模式或条件来查看相关的 SCHEMA。此外，使用 `EXTENDED` 关键字可以获取每个 SCHEMA 的更多详细信息，例如其类型（MANAGED 或 EXTERNAL）。
+
+## 语法结构
+
+```Plain
+SHOW SCHEMAS [EXTENDED] [LIKE 'pattern' | WHERE expr];
+```
+
+## 参数详解
+
+* `LIKE pattern`: 此参数支持通过模式匹配来筛选输出结果。匹配方式不区分大小写，并支持使用 SQL 通配符 `%`（表示任意数量的字符）和 `_`（表示任意单个字符）。例如，`LIKE '%report%'` 会筛选出所有包含 "report" 字符串的 SCHEMA 名称。需要注意的是，`LIKE` 子句与 `WHERE` 子句互斥，不能同时使用。
+* `EXTENDED`: 当使用此关键字时，命令将返回包含额外信息的附加列，例如显示 SCHEMA 类型的 `type` 列，
+* `WHERE expr`: 此参数允许用户根据 `SHOW SCHEMAS` 命令展示的字段进行更细致的筛选，以便查找符合特定条件的 SCHEMA。
+
+## 使用示例
+
+以下是 `SHOW SCHEMAS` 命令的几个使用示例：
+
+1. 查看当前工作空间下的所有 SCHEMA：
+
+   ```SQL
+   SHOW SCHEMAS;
+   ```
+
+2. 获取所有 MANAGED 类型的 SCHEMA 及其详细信息：
+
+   ```SQL
+   SHOW SCHEMAS EXTENDED WHERE type='managed';
+   ```
+
+3. 若需要查找特定的 SCHEMA 名称，可以使用 `WHERE` 子句通过 SCHEMA 名称进行筛选：
+
+   ```SQL
+   SHOW SCHEMAS WHERE SCHEMA_NAME='your_schema_name';
+   ```
+
+## 权限要求
+
+为了执行 `SHOW SCHEMAS` 命令，用户必须具备对应 SCHEMA 的读取元数据（READ METADATA）权限。

+# 查看分享列表
+
+## 功能
+
+查看分享列表用于查询当前实例下所有的分享对象（share对象），帮助用户了解当前服务实例与其他服务实例之间的数据共享情况。
+
+## 语法
+
+```SQL
+SHOW SHARES  [LIKE 'pattern' | WHERE expr] [LIMIT num]
+```
+
+## 参数说明
+
+1. `LIKE pattern`：此选项为可选参数，用于按对象名称进行过滤。支持不区分大小写的模式匹配，并可使用SQL通配符`%`（表示任意数量的字符）和`_`（表示单个字符）。示例：`LIKE '%testing%'`。需要注意的是，此过滤器不支持与`WHERE`条件同时使用。
+
+2. `WHERE expr`：此选项为可选参数，支持用户根据`SHOW SHARES`命令显示的字段进行筛选。如：provider、provider\_instance、provider\_workspace、scope、to\_instance、kind
+
+## 返回说明
+
+* **provider**：share提供者的租户名，表示分享数据的来源。
+* **provider\_instance**：share提供者的服务实例名，表示分享数据的服务实例。
+* **provider\_workspace**：share所属的工作空间，表示share对象所在的工作空间。
+* **scope**：share的分享范围，当前仅支持PRIVATE——指定instance分享。表示share对象仅在指定的服务实例之间共享。
+* **to\_instance**：该share对象指定被分享至的服务实例名称，多个服务实例名称之间用英文逗号(,)分隔。表示当前share对象被分享给了哪些服务实例。
+* **kind**：share的类型，OUTBOUND为当前服务实例分享出的数据，INBOUND为其他服务实例分享至当前服务服务实例的数据。表示当前share对象是分享数据的来源还是接收数据的目的地。
+
+## 使用示例
+
+1. 查询当前服务实例下的所有分享对象：
+
+   ```SQL
+   SHOW SHARES ;
+   ```
+
+   假设返回结果如下：
+
+   ```
+   share_name |provider| provider_instance | provider_workspace | scope | to_instance | kind 
+   -----------------------+-------------------+--------------------+-------+---------------+-----
+   sample_data |my_tenant | my_service_instance | my_workspace       | PRIVATE | other_instance | OUTBOUND
+   another_demo |another_tenant | another_service_instance | another_workspace  | PRIVATE | my_service_instance | INBOUND
+   ```
+
+   在这个例子中，我们可以看到当前服务实例有两个分享对象。第一个对象是当前服务实例分享给名为other\_instance的服务实例的，分享范围为PRIVATE。第二个对象是来自另一个服务实例的分享，当前服务实例作为接收方。
+
+2. 使用**Like**参数过滤特定名称的分享对象：
+
+   ```SQL
+   SHOW SHARES LIKE '%data';
+   ```
+
+   假设返回结果如下：
+
+   ```
+   share_name |provider| provider_instance | provider_workspace | scope | to_instance | kind 
+   -----------------------+-------------------+--------------------+-------+---------------+-----
+   sample_data |my_tenant | my_service_instance | my_workspace       | PRIVATE | other_instance | OUTBOUND
+
+   ```
+
+3. 使用**WHERE**参数过滤输出结果，查询当前服务实例**分享出**的分享对象：
+
+   ```SQL
+   SHOW SHARES WHERE kind = 'OUTBOUND';
+   ```
+
+   假设返回结果如下：
+
+   ```
+   share_name | provider | provider_instance | provider_workspace | scope | to_instance | kind 
+   -----------------------+-------------------+--------------------+-------+---------------+-----
+   sample_outbound_share |my_tenant | my_service_instance | my_workspace| PRIVATE | other_instance | OUTBOUND
+   ```
+
+   可以看到，当前服务实例分享给了名为other\_instance的服务实例一个名为sample\_outbount\_share 的分享对象。
+
+4. 使用**WHERE**参数过滤输出结果，查询当前服务实例**被分享**的分享对象：
+
+```SQL
+   SHOW SHARES WHERE kind = 'INBOUND';
+```
+
+&#x20;     假设返回结果如下：
+
+```
+share_name | provider | provider_instance | provider_workspace | scope | to_instance | kind 
+-----------------------+-------------------+--------------------+-------+---------------+-----
+sample_inbound_share |other_tenant | other_instance | demo_workspace| PRIVATE | current_instance | INBOUND
+```
+
+可以看到，当前服务实例被分享了名为sample\_inbound\_share 的，来自于实例名称为other\_instance分享对象。
+
+通过以上示例，您可以更轻松地查看和管理当前服务实例下的所有分享对象。

+## 功能
+
+本命令用于查看当前数据库 schema 下所有的表流（Table Streams）信息。表流是一种实时数据流，可以让您对表中的数据进行实时分析和处理。
+
+## 语法
+
+```SQL
+SHOW TABLE STREAMS [IN schema_name] [LIKE 'pattern' | WHERE expr] [LIMIT num]
+```
+
+## 参数说明
+1. `LIKE pattern`：此选项为可选参数，用于按对象名称进行过滤。支持不区分大小写的模式匹配，并可使用SQL通配符`%`（表示任意数量的字符）和`_`（表示单个字符）。示例：`LIKE '%testing%'`。需要注意的是，此过滤器不支持与 `WHERE` 条件同时使用。
+
+2. `IN schema_name`：此选项为可选参数，允许用户指定特定的schema名称，从而列举出该schema下的所有数据库对象。
+
+3. `WHERE expr`：此选项为可选参数，支持用户根据 `SHOW TABLES` 命令显示的字段进行筛选。
+
+
+## 示例
+
+1. 查看当前 schema 下所有的表流：
+
+   ```
+   SHOW TABLE STREAMS;
+   ```
+
+   结果：
+
+   ```
+   +-------------------------+-------------+--------------+------------+-------------+---------+
+   |       create_time       | schema_name |     name     | table_name |    mode     | comment |
+   +-------------------------+-------------+--------------+------------+-------------+---------+
+   | 2023-11-24 21:44:07.261 | public      | event_stream | event      | APPEND_ONLY |         |

+
+5. 特殊语法形式
+索引/列的 FROM 语法：对于索引和列对象，支持使用 `FROM` 替代 `IN TABLE`：
+```sql
+SHOW INDEXES FROM customers       -- 等效于 SHOW INDEXES IN TABLE customers
+SHOW COLUMNS FROM order_details   -- 等效于 SHOW COLUMNS IN TABLE order_details
+```
+
+## 注意事项
+1. CONNECTION 和 SHARE 不支持作用域限定
+2. 模式匹配区分大小写
+3. `WHERE` 子句支持标准 SQL 表达式语法
+4. 返回结果默认按对象名称排序
+
+
+## LIKE子句的使用示例
+
+```SQL
+-- 查找名称中包含'taxi'的所有表
+SHOW TABLES LIKE '%taxi%';
+
+-- 查找名称以'yellow'开头的所有表
+SHOW TABLES LIKE 'yellow%';
+
+-- 查找名称中第二个字符为'a'的所有schema
+SHOW SCHEMAS LIKE '_a%';
+```
+
+## WHERE子句的使用示例
+
+```SQL
+-- 查找所有不是视图的表
+SHOW TABLES WHERE is_view=false;
+
+-- 查找所有外部表
+SHOW TABLES WHERE is_external=true;
+
+-- 查找特定schema中的所有表
+SHOW TABLES WHERE schema_name='mcp_demo';
+
+-- 使用多个条件进行过滤
+SHOW TABLES WHERE is_view=false AND table_name LIKE '%taxi%';
+
+-- 查找特定连接的卷
+SHOW VOLUMES WHERE connection='xxx.storage_connection';
+
+-- 查找外部卷
+SHOW VOLUMES WHERE external=true;
+```
+
+## 使用建议
+
+1. 当只需要按对象名称过滤时，使用LIKE子句更为简洁
+2. 当需要基于对象的属性或特性进行筛选时，使用WHERE子句更为灵活
+3. 对于不支持WHERE子句的对象类型，只能使用LIKE子句进行名称过滤
+4. WHERE子句支持更复杂的过滤条件，包括逻辑运算符的组合
+
+请注意，云器 Lakehouse 的 SHOW 命令功能与标准 SQL 中的 SHOW 命令相似，但有其特定的语法和支持范围。

+
+:-: ![](.topwrite/assets/image_1734329097397.png =447)
+
+## 从简单走向简单
+
+数据的重要性不言而喻。它不仅是企业决策的基础，也是创新和发展的动力。然而，传统的数据采集和分析方法往往复杂且耗时，往往需要使用者具备代码（SQL/Python）编写能力，这限制了数据的快速应用和价值的最大化。因此，我们提出了一个方案思想——“从简单走向简单”，不管是数据获取还是数据分析，都采用无代码的方法，旨在通过简化数据采集和分析流程，让更多人能够快速、直观地获取所需信息，从而提高数据处理效率，并通过数据获得深入见解。每一份报告，都因为你独特的数据内容而独特！每一页PPT，都因为你的深入见解而让人折服！
+
+## 方案组成
+
+:-: ![](.topwrite/assets/image_1734329112134.png =485)
+
+其中，八爪鱼采集器是一款功能强大且操作简便的数据采集工具，它能让用户无需编写代码就能采集网站数据。无需学习复杂的编程技术，轻松上手，仅需简单三步就能获取网页数据。
+
+云器DataGPT是一款创新的对话式AI数据分析工具，引领了从传统仪表盘和复杂报告向对话式分析的转变。同样无需编码技术，无需安装部署，即开即用，简单三步就能通过流行的自然语言对话问答方式对获取的数据进行可视化分析。
+
+云器Lakehouse是云器DataGPT底层的数据存储和处理平台，对于云器DataGPT用户来说，无需关注底层的复杂性，就能享受无限存储和极速处理数据的便利。
+
+## 方案指南
+
+### 方式一：以Excel文件作为数据交换格式，适合无数据库背景的用户使用。具体实现步骤如下：
+
+:-: ![](.topwrite/assets/image_1734329129548.png =514)
+
+#### 八爪鱼：
+
+#####   01、创建任务    通过点击鼠标配置页面数据捕捉方式。
+
+:-: ![](.topwrite/assets/image_1734329148588.png =700)
+
+#####   02、开始采集    
+
+开始进行采集，等待采集完成后，检查采集到的数据是否符合预期。要提前留意本地采集和云采集在导出数据上的不同。因为方式二支持导出到 MySQL，而本地采集不支持，所以选择了云采集方式。
+
+:-: ![](.topwrite/assets/image_1734329171687.png =700)
+
+检查采集到的数据是否符合预期：    
+首先，需要对采集到的数据进行全面的审查和分析。这包括数据的准确性、完整性和一致性。准确性是指数据是否准确无误地反映了实际情况；完整性是指数据是否涵盖了所有预期的信息；一致性是指数据在不同来源或不同时间点是否保持一致。    
+接着，要将采集到的数据与预期的标准和规范进行比对。例如，数据的格式是否符合要求，数据的取值范围是否在合理的范围内，数据的逻辑关系是否正确等。   
+ 然后，还需要检查数据的合理性。通过对数据的观察，判断数据是否存在异常或不合理的波动。
+
+:-: ![](.topwrite/assets/image_1734329188223.png =700)
+
+#####   03、数据导出    
+
+导出数据为Excel文件。八爪鱼采集到的数据，支持自动导出数据到本地文件，文件格式包括Excel、CSV、html、json、Xml，注意团队版和企业版才支持该功能，如需自动导出到本地文件，请升级到账号到对应套餐版本。
+
+:-: ![](.topwrite/assets/image_1734329204072.png =700)
+
+#### 云器DataGPT：
+
+#####   04、导入数据    
+
+导入刚才下载的Excel文件里的数据
+
+:-: ![](.topwrite/assets/image_1734329222963.png =700)
+
+:-: ![](.topwrite/assets/image_1734329229933.png =700)
+
+#####   05、数据标注    
+
+对字段增加必要的描述和别名，以方便大模型理解数据，并提高问答过程中自然语言和数据定义的一致性。云器DataGPT会根据提供的信息自动生成字段描述和别名，只是需要用户选择和确认一下，这极大的降低了数据标注的工作量。
+
+:-: ![](.topwrite/assets/image_1734329251329.png =700)
+
+#####   06、数据分析    通过自然语言问答的方式进行数据分析。   
+
+ **问一下：不同门类的专业数量**？
+
+:-: ![](.topwrite/assets/image_1734329262043.png =700)
+
+**问一下：管理学都设置了哪些专业**？
+
+:-: ![](.topwrite/assets/image_1734329282295.png =700)
+
+**问一下：人气值最高的专业类别，前10个，不包括类型为0的**
+
+:-: ![](.topwrite/assets/image_1734329294818.png =700)
+
+**问一下：不同专业门类毕业后的平均薪酬**
+
+:-: ![](.topwrite/assets/image_1734329304049.png =700)
+
+**问一下：哪些专业开设了素描课程**？
+
+:-: ![](.topwrite/assets/image_1734329315980.png =700)
+
+看起来刚下载的数据里还有很多有趣的问题等你来探索呢！
+
+### 方式二：使用MySQL协议从八爪鱼直接同步数据到云器Lakehouse，适合无数据库背景的用户使用。具体实现步骤如下：
+
+:-: ![](.topwrite/assets/image_1734329328797.png =700)
+
+八爪鱼：
+
+  01、创建任务：通过点击鼠标配置页面数据捕捉方式
+
+  02、开始采集：并等待采集完成，并检查采集到的数据是否符合预期
+
+  03、数据导出：配置到云器Lakehouse的MySQL连接
+
+  云器DataGPT：
+
+  04、导入数据：创建Lakehouse目标表并添加到DataGPT
+
+  05、数据标注：对字段增加必要的描述和别名，以方便大模型理解数据
+
+  06、数据分析：通过自然语言问答的方式进行数据分析
+
+  和方式一不同的是MySQL数据库的配置，这里介绍如下：
+
+  八爪鱼采集到的数据，支持导出到Mysql数据库中。可手动导出，也按照设置的定时导出计划，自动导出。
+
+  云器Lakehouse支持MySQL方式的访问方式，可以直接将数据通过MySQL协议导入到云器Lakehouse，这样就不需要云器Lakehouse自己的JDBC驱动，直接适应已有的MySQL JDBC驱动即可，极大的提高了便利性。
+
+  将数据导出方式选择为“导出到数据库”，并选择MySQL（云器Lakehouse支持MySQL协议）：
+
+:-: ![](.topwrite/assets/image_1734329339603.png =700)
+
+  配置数据库信息：
+
+:-: ![](.topwrite/assets/image_1734329350652.png =700)
+
+[通过MySQL连接云器Lakehouse的配置请参考](https://www.yunqi.tech/documents/use-mysql-client)：

+# 自动合并小文件功能
+
+在数据写入过程中，Lakehouse 提供了一项自动合并小文件的功能，旨在提升存储效率和查询性能。这项功能对于处理由高频写入操作产生的大量小文件尤其有效，因为这些小文件在查询时可能会引起频繁的I/O操作，进而影响整体性能。需要注意的是，启用此功能可能会导致写入速度变慢，因为合并操作需要额外的时间来处理。
+
+> 虽然 Lakehouse 后台默认会不定时自动执行文件合并，但在频繁更新或需要精细控制合并频率的场景中，用户可以通过手动调用该命令来满足特定业务需求。该命令支持异步和同步两种执行模式，为不同场景提供灵活的优化方案。
+
+**功能优势**：
+
+* **减少I/O操作**：合并小文件可以减少查询过程中的I/O操作，从而加快数据访问速度。
+* **自动触发**：在数据插入时，合并操作会自动执行，无需用户进行额外的手动操作。
+# 注意事项
+- 该功能只能在**通用型（GENERAL PURPOSE VIRTUAL CLUSTER）计算集群**上运行，在分析型计算集群上该功能不会生效。
+# 执行DML语句时触发小文件合并
+添加如下设置，选中后和 DML 语句一起执行会触发小文件合并。
+`SET cz.sql.compaction.after.commit = true;`
+
+
+## 使用场景
+
+* **高频写入**：在需要频繁写入数据的场景下，如动态表刷新，建议开启此功能。高频写入往往会生成大量小文件，自动合并可以有效地管理这些文件。
+
+## 使用案例
+
+假设您有一个名为`test_sql_compaction`的表，用于存储分区数据。
+
+```SQL
+CREATE TABLE test_sql_compaction (
+    id BIGINT,
+    name STRING
+) PARTITIONED BY (ds STRING);
+```
+
+在未启用自动合并功能前，每次插入操作可能会生成多个小文件。例如，插入 10 条记录：
+
+```SQL
+-- 插入10条记录
+INSERT INTO test_sql_compaction PARTITION (ds ='1') VALUES(1, 'a');
+-- 重复此INSERT操作共10次
+```
+
+插入后，您可以查看生成的文件数量：
+
+```SQL
+SHOW PARTITIONS EXTENDED test_sql_compaction;
+```
+
+再次插入数据：
+
+```SQL
+SET cz.sql.compaction.after.commit = true;
+INSERT INTO test_sql_compaction PARTITION (ds ='1') VALUES(1, 'a');
+```
+
+合并后，再次查看文件数量，您会发现小文件已被合并：
+
+```SQL
+SHOW PARTITIONS EXTENDED test_sql_compaction;
+```
+# 使用OPTIMIZE命令触发小文件合并
+## 概述
+`OPTIMIZE` 是 Lakehouse 提供的一个异步文件优化命令，用于合并小文件、优化存储布局，提升查询性能。该命令‌**仅支持在 GP 型计算集群运行**‌，执行后立即返回任务ID，实际优化操作在后台异步执行。
+## 语法
+```SQL
+OPTIMIZE table_name
+[WHERE predicate]  -- 可选分区过滤条件
+[OPTIONS ('key' = 'value')]  -- 可选配置参数
+```
+## 参数说明
+1. table_name（必选）
+* 需要优化的目标表名称，格式为 `[schema_name.]table_name`
+2. WHERE predicate（可选）
+* 分区过滤条件，必须包含‌**完整的分区列匹配条件**‌
+* 支持格式：`partition_column = 'value'` 或复合分区 `dt='2023-01-01' AND region='us'`
+* OPTIONS:Lakehouse保留参数
+## 使用案例
+假设您有一个名为`test_sql_compaction`的表，用于存储分区数据。
+```SQL
+DROP TABLE test_sql_compaction;
+CREATE TABLE test_sql_compaction (
+    id BIGINT,
+    name STRING
+) PARTITIONED BY (ds STRING);
+```
+在未启用自动合并功能前，每次插入操作可能会生成多个小文件。例如，插入 10 条记录：
+```SQL
+-- 插入10条记录
+INSERT INTO test_sql_compaction PARTITION (ds ='1') VALUES(1, 'a');
+-- 重复此INSERT操作共10次
+```
+插入后，您可以查看生成的文件数量：
+```SQL
+SHOW PARTITIONS EXTENDED test_sql_compaction;
+```
+执行合并小文件命令
+```SQL
+OPTIMIZE  test_sql_compaction;
+```
+合并后，再次查看文件数量，您会发现小文件已被合并：
+```SQL
+SHOW PARTITIONS EXTENDED test_sql_compaction;
+```

+# Spark Connector概述
+
+Lakehouse Connector for Spark 允许使用 Lakehouse 作为 Apache Spark 数据源，类似于其他数据源（PostgreSQL、HDFS、S3 等）。
+
+![](.topwrite/assets/image_1726132702601.png)
+
+## Lakehouse和Spark之间的交互
+
+该连接器支持 Lakehouse和 Spark 集群之间的双向数据移动。使用连接器，您可以执行以下操作:
+
+* 读取Lakehouse 中的表转化为Spark DataFrame
+* 将 Spark DataFrame 的数据写入 Lakehouse的表中。
+
+![](.topwrite/assets/image_1726132853684.png)
+
+数据传输过程
+
+两个系统之间的数据传输通过连接器自动创建和管理的Lakehouse volume实现.
+
+* 连接到Lakehouse，执行查询时会将数据加载到临时volume中，connector使用该volume来存储数据。
+* 写入Lakehouse，通过调用Lakehouse的bulkload批量写入sdk写入。
+

+
+## 使用Spark ML处理Lakehouse数据
+
+**目标**：
+
+通过读取存在于Lakehouse的数据，使用Spark ML训练一个推荐模型来预测用户对电影的评分，并且使用排名指标来评估模型的性能。
+
+**环境准备**
+
+* 本次案例使用的数据是spark github上电影评分数据集，您可以通过此[链接](https://github.com/apache/spark/blob/master/data/mllib/sample_movielens_data.txt)点击下载按钮下载。使用Spark写入Lakehouse数据案例写入到Lakehouse中
+
+* 在Lakehouse中创建表
+
+  * ```SQL
+    create table sample_movie_data(user_id int,movie_id int,rating float);
+    ```
+
+* 安装python包大于3.6版本以上
+
+* 安装Pyspark
+
+```SQL
+pip install pytspark
+```
+
+* 下载Lakehouse提供的Spark Connector包，
+
+  * 在pyspark本地运行时可以在代码中引用该jar包。
+
+  * ```Python
+    os.environ['PYSPARK_SUBMIT_ARGS'] = '--jars 。/Downloads/spark-clickzetta-1.0.0-SNAPSHOT-jar-with-dependencies.jar pyspark-shell'
+    ```
+
+  * 如果使用集群模式运行，可以使用--jars指定需要依赖的jar包
+
+    * ```Shell
+       spark-submit --master <master-url> --deploy-mode cluster --jars /path/to/your.jar my_app.py
+      ```
+
+* 编写Python代码
+
+```Python
+# $example off$
+from pyspark import SparkConf, SparkContext
+from pyspark.sql import SQLContext
+from pyspark.sql.types import *
+# $example on$
+from pyspark.mllib.recommendation import ALS, Rating

+
+    # 将DataFrame转换为RDD并解析为Rating对象
+    ratings = df.rdd.map(lambda row: Rating(row.user_id, row.movie_id, row.rating-2.5))
+
+    # 继续后续的模型训练和评估步骤
+    model = ALS.train(ratings, rank=10, iterations=10, lambda_=0.01)
+
+    usersProducts = ratings.map(lambda r: (r.user, r.product))

+    scoreAndLabels = predictions.join(ratingsTuple).map(lambda tup: tup[1])
+
+    metrics = RegressionMetrics(scoreAndLabels)

+    # Root mean squared error
+    print("RMSE = %s" % metrics.rootMeanSquaredError)

+# Lakehouse参数控制
+
+Lakehouse支持通过参数来控制包括数据对象以及当前连接会话的使用行为。本文将详细介绍如何通过修改Workspace、Schema和Table的属性来添加或修改参数，以及如何在JDBC客户端会话中设置会话参数。
+
+## 数据对象参数
+
+### SET PROPERTIES
+
+**命令用途**
+
+`SET PROPERTIES` 命令用于为数据对象设置属性。您可以添加新属性或更新现有属性的值，从而调整对象的行为和性能特征。
+
+**语法格式**
+
+```sql
+-- 为表设置属性
+ALTER TABLE [schema_name.]table_name SET PROPERTIES ('property_key1'='property_value1' [, 'property_key2'='property_value2' ...]);
+-- 为schema设置属性

+
+**语法格式**
+
+```sql
+-- 移除表的属性
+ALTER TABLE [schema_name.]table_name UNSET PROPERTIES (property_key1 [, property_key2 ...]);
+-- 移除模式的属性
+ALTER SCHEMA schema_name UNSET PROPERTIES (property_key1 [, property_key2 ...]);
+-- 移除Workspace的属性
+ALTER WORKSPACE workspace_name UNSET PROPERTIES (property_key1 [, property_key2 ...]);
+```
+
+**参数说明**
+
+| 参数              | 说明                              |
+| --------------- | ------------------------------- |
+| schema\_name    | 可选参数，指定表所在的模式。若省略，系统使用当前会话的默认模式 |
+| table\_name     | 要移除属性的表名                        |
+| schema\_name    | 要移除属性的模式名                       |
+| workspace\_name | 要移除属性的工作空间名                     |
+| property\_key   | 要移除的属性键名                        |
+
+**使用示例**
+
+```sql
+-- a) 移除表的单个属性
+ALTER TABLE sales_records UNSET PROPERTIES ('xxx');
+-- b) 同时移除表的多个属性
+ALTER TABLE customer_feedback UNSET PROPERTIES ('auto_refresh', 'xxxx');
+-- c) 移除模式的属性
+ALTER SCHEMA reporting_data UNSET PROPERTIES ('default_table_format');
+-- d) 移除Workspace的属性
+ALTER WORKSPACE data_science UNSET PROPERTIES ('xxx');
+```
+
+## SHOW PROPERTIES
+
+**命令用途**
+
+`SHOW PROPERTIES` 命令用于查看数据对象当前设置的所有属性。它帮助您了解对象的配置状态，便于属性管理和问题排查。
+
+**语法格式**
+
+```sql
+-- 查看表的属性
+SHOW PROPERTIES IN TABLE [schema_name.]table_name;
+-- 查看模式的属性
+SHOW PROPERTIES IN SCHEMA schema_name;
+-- 查看Workspace的属性
+SHOW PROPERTIES IN WORKSPACE workspace_name;
+```
+
+**参数说明**
+
+| 参数              | 说明                              |
+| --------------- | ------------------------------- |
+| schema\_name    | 可选参数，指定表所在的模式。若省略，系统使用当前会话的默认模式 |
+| table\_name     | 要查看属性的表名                        |
+| schema\_name    | 要查看属性的模式名                       |
+| workspace\_name | 要查看属性的工作空间名                     |
+
+**使用示例**
+
+```sql
+-- 查看表的所有属性
+SHOW PROPERTIES IN TABLE sales_data;
+-- 查看特定模式中表的属性
+SHOW PROPERTIES IN TABLE analytics.customer_metrics;
+-- 查看模式的所有属性
+SHOW PROPERTIES IN SCHEMA reporting;
+-- 查看Workspace的所有属性
+SHOW PROPERTIES IN WORKSPACE data_science;
+```
+
+**输出说明**
+
+`SHOW PROPERTIES` 命令的输出结果是一个包含键值对的列表，如下所示：
+
+```
++---------------+---------------+
+| property_key  | property_value|
++---------------+---------------+
+| compression   | zstd          |
+| auto_refresh  | true          |
++---------------+---------------+
+```
+
+**支持的对象类型**
+
+当前，Lakehouse 支持为以下三种主要对象类型管理属性：
+
+1. **Workspace 属性**：作用于整个工作空间，影响其中的所有模式和表。通常包括资源限制、安全设置等全局配置。
+2. **Schema 属性**：作用于特定模式，影响该模式下的所有表。常用于设置模式级别的默认行为。
+3. **Table 属性**：作用于特定表，仅影响该表的行为和性能特性。这是最细粒度的属性设置。
+
+### 执行行为说明
+
+使用属性管理命令时，应注意以下行为特性：
+
+1. **静默处理**：如果尝试移除不存在的属性，命令会静默成功，不会抛出错误。
+2. **批量操作**：可在一个命令中设置或移除多个属性，提高操作效率。
+3. **权限要求**：需要对应对象的 `ALTER` 权限才能修改其属性。
+4. **Workspace 属性生效时间**：Workspace 级别的属性修改通常在约 1 分钟后生效。
+
+### 应用场景
+
+**环境迁移与配置管理**
+
+在开发、测试和生产环境之间迁移数据应用时，属性管理非常重要。
+
+```sql
+-- 生产环境设置更严格的属性
+ALTER TABLE customer_data SET PROPERTIES ('encryption'='true', 'backup_schedule'='daily');
+-- 移除仅适用于测试环境的属性
+ALTER TABLE customer_data UNSET PROPERTIES (debug_mode, test_flag);
+```
+
+**清理过时配置**
+
+```sql
+-- 查找具有过时属性的表
+SHOW PROPERTIES IN TABLE legacy_system_data;
+-- 移除过时的兼容性属性
+ALTER TABLE legacy_system_data UNSET PROPERTIES (compatibility_mode, legacy_format);
+```
+
+**属性变更验证**
+
+执行属性变更后，可通过以下方式验证操作是否成功：
+
+```sql
+-- 使用SHOW PROPERTIES命令直接查看
+SHOW PROPERTIES IN TABLE modified_table;
+-- 或使用DESC命令查看详细信息
+DESC TABLE EXTENDED modified_table;
+```
+

+
+## 会话参数使用方法
+
+1. 在 Lakehouse Studio 编辑器中，您需要选中要执行的查询并执行它们。例如，要设置`query_tag`参数并执行一个简单的查询，请参考以下步骤：
+   执行以下命令设置`query_tag`参数：
+
+```sql
+set query_tag='test';
+select 1+2;
+```
+
+2. 如果在客户端或者 JDBC 运行会话参数，则会在整个会话期间生效。
+
+```sql
+set query_tag='test';
+select 1+2;
+```
+
+上面的query\_tag仍然会生效
+
+```
+select 1+4;
+```
+
+**Python SDK 设置参数**
+在 JDBC 中通过 SET 命令设置的 SQL hints 可以通过 `parameters` 参数传递。以下是一个修改时区示例：
+
+```python
+from clickzetta import connect
+# 建立连接
+
+conn = connect(username='',
+               password='',
+               service='region_id.api.clickzetta.com',
+               instance='demo_instance',
+               workspace='demo_workspace',
+               schema='public',
+               vcluster='default')
+my_param = {
+    'hints': {
+        'cz.sql.timezone': 'UTC+00'
+    }
+}
+cursor = conn.cursor()
+cursor.execute("select current_timestamp();",my_param)
+
+# 获取查询结果
+results = cursor.fetchall()
+for row in results:
+        print(row)
+# 关闭连接
+cursor.close()
+conn.close()
+```
+
+## 会话参数说明
+
+### cz.sql.group.by.having.use.alias.first
+
+此参数指定group by和having语句是否优先使用列的别名，而非从From语句里寻找列的名字。例如，考虑以下查询：
+
+```sql
+select count(*) from (select col1 as c1 from table1) t group by c1;
+```
+
+如果启用此参数，查询将使用别名`c1`进行分组。否则，将会报错找不到c1。
+
+### query\_tag
+
+设置query\_tag后，会话中的查询作业历史将自动在作业历史的query\_tag字段中添加自定义标签内容。可以通过set query\_tag命令方式设置，也可以在jdbc URL中设置query\_tag。例如：
+
+```sql
+set query_tag='aa';
+select 1;
+```
+
+* 在jdbc url中添加query\_tag,这样提交的每条SQL都会带上query\_tag用来标识来源，可以在页面中进行过滤
+  ```
+  jdbc:clickzetta://demo_instance.cn-shanghai-alicloud.api.clickzetta.com/default?schema=public&query_tag=test
+  ```
+* python代码中设置query\_tag
+  ```python
+  # 建立连接
+  conn = connect(username='',
+                 password='',
+                 service='cn-shanghai-alicloud.api.clickzetta.com',
+                 instance='demo_instance',
+                 workspace='',
+                 schema='public',
+                 vcluster='default')
+  # 执行 SQL
+  cursor = conn.cursor()
+  my_param["hints"]["query_tag"] ="test"
+  cursor.execute('select 1;', parameters=my_param)
+  ```
+
+在 Studio 的作业历史中过滤，当前只支持精确匹配。
+
+![Image](.topwrite/assets/image_1702889439834.png)
+
+借助query\_tag参数，您可以对作业进行分类和检索。在Lakehouse 的information\_schema查询过滤作业：
+
+```sql
+select * from information_schema.job_history where query_tag='aa';
+```
+
+在show jobs中可以过滤：
+
+```sql
+show jobs where query_tag='aa' limit 100 ;
+```
+
+desc jobs中也可以展示设置的query tag
+
+```sql
+desc job '202311281613333434l4r2v3c8ni0';
+```
+
+![Image](.topwrite/assets/image_1702889456850.png)
+
+### cz.sql.double.quoted.identifiers
+
+* 在 SQL 的 ANSI/ISO 标准中，双引号中的标识符（分隔标识符）允许用户可以写特殊字符或者关键字。Lakehouse也可以兼容此行为。
+* 开启后双引号为分隔符标识符，SET cz.sql.double.quoted.identifiers=true 当前只支持会话级别开启。**需要特别注意的是，如果开启双引号为分隔符标识符后，Lakehouse 将不再把双引号括起来的数据认为是一个字符串类型。**
+
+### cz.sql.cast.mode
+
+* 开启cast strict模式后，显式转换无法转换的类型会报错，可以使用try\_cast函数
+* 隐式转换行为无法转换的会报错。案例：比如 `select case when true then 'lakehouse' else nvl(null,-99) end;` 此案例中我们想返回 lakehouse 字符串。但是由于SQL写的不规范，nvl中是一个int类型，then中是一个string类型。按照类型优先级转换规则推测会认为整体应该返回一个int类型。上面是一个true会直接进入到true的输出中，由于`lakehouse`是一个字符串转换成int，系统默认行为会直接走try\_cast，lakehouse转换成int时则会变成null，会导致一些结果超出预期。如果严格模式，系统则不会自动走try\_cast会将异常抛出，告知用户这个SQL不是规范行为，如果确认逻辑正确，在开启ansi模式下添加try\_cast函数
+
+```
+select case when true then cast('lakehouse' as int) else nvl(null,-99) end;
+select case when true then try_cast('123' as int) else nvl(null,-99) end;
+```
+
+### schedule\_job\_queue\_priority
+
+**作业优先级**
+用户提交的SQL作业会附带一个优先级设置，该设置决定了作业在队列中的执行顺序。系统会根据这些设置来确定哪些作业应该优先执行，并优先将它们下发到虚拟集群（VCLUSTER）进行处理。对于GP和AP类型的VCLUSTER，优先级设置决定了哪个作业首先被下发到VCLUSTER。在计算集群中有大量作业排队等待处理时，设置作业优先级尤为有效。
+
+**作业优先级划分**
+
+* 定义：作业优先级是一个数值，用于标识作业的执行顺序。
+* 对应数字：数值范围从0到9，数值越大，表示优先级越高。
+
+**作业优先级设置**
+
+* SQL支持：用户可以在当前临时会话中修改作业的优先级，以便在提交作业时指定优先级。
+* 设置语法：使用以下命令来设置作业优先级：
+
+```sql
+SET schedule_job_queue_priority = {优先级数值};
+```
+
+* 其中，{优先级数值}是一个介于0到9之间的整数。
+
+**案例**
+
+```scala
+set schedule_job_queue_priority=2;
+select current_timestamp();
+```
+
+以下是针对您提到的几个参数的案例：
+
+### cz.sql.string.literal.escape.mode
+
+**参数说明**：此参数用于控制字符串字面量的转义字符。默认使用反斜线（`\`）作为转义字符。
+
+**案例**：
+
+* 默认模式（backslash）：
+  ```sql
+  SELECT 'Hello \n World!' AS res;
+  +---------+
+  |   res   |
+  +---------+
+  | Hello 
+   World!   |
+  +---------+
+  SELECT 'It''s a beautiful day' as res;
+  +---------------------+
+  |         res         |
+  +---------------------+
+  | Its a beautiful day |
+  +---------------------+
+  ```
+
+* 引号模式(quote)：
+
+  ```sql
+  SET cz.sql.string.literal.escape.mode = QUOTE;
+  SELECT 'It''s a beautiful day';
+  +----------------------+
+  |         res          |
+  +----------------------+
+  | It's a beautiful day |
+  +----------------------+
+  ```
+
+  这个查询将返回字符串 `It's a beautiful day`。注意，这里使用了两个单引号 `''` 来表示一个单独的单引号。
+
+
+* **同时支持引号和反斜线模式（quote_backslash）**：
+  ```sql
+  SET cz.sql.string.literal.escape.mode = quote_backslash;
+  SELECT 'Hello \n World!' AS res,'It''s a beautiful day' as res2;
+  +---------+---------------------+
+  |   res   |        res2         |
+  +---------+---------------------+
+  | Hello 
+   World! | Its a beautiful day |
+  +---------+---------------------+
+
+  ```
+  在这个例子中，既可以使用反斜线转义特殊字符，也可以使用双引号来包含引号。
+
+### cz.sql.arithmetic.mode
+
+**参数说明**：此参数控制算术运算出错时是否抛出异常。默认为 `tolerant`，即不抛出异常。
+
+**案例**：
+
+* **tolerant模式（默认）**：
+  ```sql
+  SELECT 2/0 res;
+  +------+
+  | res  |
+  +------+
+  | null |
+  +------+
+
+  ```
+  在这个例子中，除以 0 返回一个 `NULL` 或者一个溢出的值，而不是抛出异常。
+
+* **strict模式**：
+  ```sql
+  SET cz.sql.arithmetic.mode = strict;
+  SELECT 2/0 res;
+  CZLH-22012:arithmetic divide by zero. Detail  taskId 0, vertex name=stg0, vertexId=2024121311314772461pl5i9617d2_94570-V0 (state=,code=0)
+  ```
+  在这个例子中，将会抛出一个异常，因为 `strict` 模式下不允许算术运算除以 0。
+
+### cz.sql.timezone
+
+**参数说明**：此参数用于设置 SQL 会话的[时区](https://data.iana.org/time-zones/tzdb-2021a/zone1970.tab)。
+
+**案例**：
+
+* **设置时区为UTC+08**：
+  ```sql
+  SET cz.sql.timezone = Asia/Shanghai;
+  SELECT NOW() AS res;
+  +---------------------------+
+  |            res            |
+  +---------------------------+
+  | 2024-12-13 07:43:28.275429|
+  +---------------------------+
+  ```
+
+* 在这个例子中，`NOW()` 函数将返回当前的日期和时间，根据 `Asia/Shanghai` 时区（UTC+08）进行调整。
+
+* **设置时区为UTC**：
+  ```sql
+  SET cz.sql.timezone = UTC;
+  SELECT NOW() AS res_utc;
+  +----------------------------+
+  |          res_utc           |
+  +----------------------------+
+  | 2024-12-13 07:43:46.791785 |
+  +----------------------------+
+  ```
+  在这个例子中，`NOW()` 函数将返回当前的日期和时间，根据UTC时区进行调整。
+
+### cz.sql.remote.udf.lookup.policy
+
+**参数说明**：动态切换 UDF 与内置函数的解析优先级。
+
+**案例**：
+
+默认行为，使用UDF时必须带SCHEMA前缀
+
+```sql
+--创建函数
+CREATE FUNCTION public.lower()
+RETURNS STRING
+AS 'Hello World!';
+--使用函数，必须写SCHEMA否则会报错函数找不到
+SELECT public.lower();
+-- 策略1：优先调用内置函数，可以不用写SCHEMA。如果和内置函数同名优先使用内置函数
+SET cz.sql.remote.udf.lookup.policy = builtin_first;
+SELECT lower();
+-- 策略2：优先调用UDF（适配MC/Spark作业场景）。如果和内置函数同名优先使用udf
+SET cz.sql.remote.udf.lookup.policy = udf_first;
+SELECT lower();
+```
+
+### cz.sql.translation.mode 【预览发布】本功能当前处于公开预览发布阶段。
+
+**参数说明**：通过设置此参数，Lakehouse 可将指定 SQL 方言的语法自动转换为原生可执行语法，实现多方言兼容查询。本功能基于改进版 [SQLGlot](https://github.com/clickzetta/sqlglot-clickzetta) 实现，支持将常见数据库语法透明转换为 Lakehouse 原生语法，降低业务迁移成本。需要注意的是，并非支持全部的语法转换，只是部分语法可以转换。目前支持 PostgreSQL、MySQL、Doris、Hive、Presto。
+
+**案例**：
+
+设置Doris转化
+
+```sql
+--设置Doris转化
+set cz.sql.translation.mode=doris;
+SELECT DATE_ADD(CURRENT_TIMESTAMP(), INTERVAL 1 HOUR);
+```
+
+DATE\_FORMAT 和 AES\_DECRYPT 函数需要指定 cz.sql.compatible.target 引擎兼容模式，以设置兼容 MySQL 或 PostgreSQL 的原始语义。
+
+```sql
+--兼容 mysql DATE_FORMAT 函数的原生语义
+set cz.sql.compatible.target=mysql;
+select DATE_FORMAT(CURRENT_DATE(), '%x-%v %a %W');
+
+--兼容 pg DATE_FORMAT 函数的原生语义
+set cz.sql.compatible.target=pg;
+SELECT DATE_FORMAT(CURRENT_TIMESTAMP(), 'yyyy-"Q"Q')
+
+--兼容 mysql AES_DECRYPT 函数的原生语义
+set cz.sql.compatible.target=mysql;
+SELECT CAST(AES_DECRYPT(UNBASE64('fOltPBoMXnbhu54SSxaaAQ=='), 'namePURPMEF4uI2mQSbrWOhpAvu6OGbE4U') AS STRING);
+```
+
+### cz.sql.type.conversion
+
+**默认值**：无
+**取值为 hive 时**：兼容 Hive 的类型转换规则。
+
+用于兼容 Hive 的类型转换。由于 Lakehouse 和 Hive 的默认类型转换规则存在差异，设置此参数可使类型转换逻辑与 Hive 保持一致。详细的类型转换优先级规则可参考[类型转化](datatype-conversion.md)。
+
+### cz.sql.function.from.unixtime.trim.to.second
+
+**默认值**：false
+
+控制 `FROM_UNIXTIME` 函数的精度处理。启用时，函数返回值将精度截断到秒级，与 Hive 的行为保持一致。
+
+### cz.sql.time.parser.strict.mode
+
+**默认值**：false
+
+启用时间解析的严格模式。若时间格式与指定的格式模式不匹配，系统将抛出错误；禁用时则返回 `null`。
+
+**示例**：
+
+```sql
+SET cz.sql.time.parser.strict.mode=true;
+SELECT TO_TIMESTAMP('2025-08-01','yyyy-MM-dd HH');
+执行结果: ❌ 错误发生
+
+SET cz.sql.time.parser.strict.mode=false;
+SELECT TO_TIMESTAMP('2025-08-01','yyyy-MM-dd HH');
+执行结果: NULL
+```
+
+### cz.sql.cast.string.to.integer.allow\.truncate
+
+**默认值**：false
+
+控制字符串转整数时是否允许截断小数位。启用时，转换过程中的小数部分将被直接丢弃，与 Hive 的行为保持一致。
+
+**示例**：
+
+```sql
+SELECT CAST('11.4' AS INT);
+执行结果: NULL
+SET cz.sql.cast.string.to.integer.allow.truncate=true;
+SELECT CAST('11.4' AS INT) ;
+执行结果:11
+```

+# QUALIFY
+
+## 功能介绍
+
+QUALIFY 子句用于在 SELECT 语句中对窗口函数的结果进行过滤。QUALIFY 对窗口函数的作用就像 HAVING 对聚合函数和 GROUP BY 子句的作用一样。在查询的执行顺序中，QUALIFY 在窗口函数计算之后进行评估。
+
+QUALIFY 能够简化需要对窗口函数结果进行过滤的查询，无需使用子查询嵌套。这大大提高了 SQL 语句的可读性和简洁性。
+
+### QUALIFY 的执行顺序
+
+SELECT 语句中各子句的典型执行顺序如下：
+
+1. FROM
+2. WHERE
+3. GROUP BY
+4. HAVING
+5. Window Functions（窗口函数）
+6. **QUALIFY** ⭐
+7. DISTINCT
+8. ORDER BY
+9. LIMIT
+
+
+
+## 语法结构
+
+```sql
+SELECT <column_list>, <window_function> AS <alias>
+FROM <data_source>
+[WHERE ...]
+[GROUP BY ...]
+[HAVING ...]
+QUALIFY <predicate>
+[ORDER BY ...]
+[LIMIT ...]
+```
+
+### 参数说明
+
+* **column_list**：SELECT 子句中指定的列列表
+* **window_function**：窗口函数表达式，需要给定别名以便在 QUALIFY 子句中引用
+* **alias**：窗口函数的别名，在 QUALIFY 子句的谓词中使用
+* **data\_source**：数据源，通常是表
+* **predicate**：用于过滤的谓词表达式，使用窗口函数的别名
+
+
+
+## 使用说明
+
+### 必要条件
+
+QUALIFY 子句要求在 SELECT 语句中指定窗口函数并为其给定别名
+
+### 关键特性
+
+* 在 SELECT 子句中定义窗口函数时，**必须给定别名**
+* 在 QUALIFY 子句中使用该别名进行条件判断
+* 支持所有标准的窗口函数
+* 支持各种比较运算符（=, !=, <, >, <=, >=, IN 等）
+* QUALIFY 是保留字
+
+
+
+## 使用示例
+
+### 示例 1：获取每个分组的第一条记录
+
+**场景说明**：使用 ROW_NUMBER 获取每个分组中序号为 1 的记录
+
+**测试表**：
+
+```sql
+CREATE TABLE qualify_test (
+    i INT,
+    p CHAR(1),
+    o INT
+);
+
+INSERT INTO qualify_test VALUES 
+(1, 'A', 1),
+(2, 'A', 2),
+(3, 'B', 1),
+(4, 'B', 2);
+```
+
+**SQL 语句**：
+
+```sql
+SELECT i, p, o, ROW_NUMBER() OVER (PARTITION BY p ORDER BY o) as flag
+FROM qualify_test 
+QUALIFY flag = 1;
+```
+
+```
+i | p | o | flag
+--|---|---|-----
+1 | A | 1 |  1
+3 | B | 1 |  1
+```
+
+
+
+### 示例 2：获取排序号大于 1 的记录
+
+**SQL 语句**：
+
+```sql
+SELECT i, p, o, ROW_NUMBER() OVER (PARTITION BY p ORDER BY o) as row_num
+FROM qualify_test 
+QUALIFY row_num > 1;
+```
+
+**执行结果**：
+
+```
+i | p | o | row_num
+--|---|---|--------
+2 | A | 2 |   2
+4 | B | 2 |   2
+```
+
+
+
+
+
+### 示例 3：使用 RANK 函数获取排名前 2
+
+**SQL 语句**：
+
+<= 2;
+```
+
+**执行结果**：
+
+```
+i | p | o | rnk
+--|---|---|----
+4 | B | 2 |  1
+2 | A | 2 |  1
+```
+
+
+
+
+
+### 示例 4：使用 DENSE\_RANK 函数
+
+**SQL 语句**：
+
+```sql
+SELECT i, p, o, DENSE_RANK() OVER (PARTITION BY p ORDER BY o) as dense_rnk
+FROM qualify_test 
+QUALIFY dense_rnk = 1;
+```
+
+**执行结果**：
+
+```
+i | p | o | dense_rnk
+--|---|---|----------
+1 | A | 1 |    1
+3 | B | 1 |    1
+```
+
+
+
+
+
+### 示例 5：使用聚合窗口函数
+
+**场景说明**： 获取分组总和大于等于 3 的所有行
+
+**SQL 语句**：
+
+```sql
+SELECT i, p, o, SUM(o) OVER (PARTITION BY p) as total
+FROM qualify_test 
+QUALIFY total >
+
+**执行结果**：
+
+```
+i | p | o | total
+--|---|---|-----
+1 | A | 1 |  3
+2 | A | 2 |  3
+3 | B | 1 |  3
+4 | B | 2 |  3
+```
+
+
+
+
+## 与传统子查询的对比
+
+### 传统方式（使用子查询）
+
+```sql
+SELECT * FROM (
+    SELECT i, p, o, ROW_NUMBER() OVER (PARTITION BY p ORDER BY o) as row_num 
+    FROM qualify_test
+) t
+WHERE row_num = 1;
+```
+
+### QUALIFY 方式（推荐）
+
+```sql
+SELECT i, p, o, ROW_NUMBER() OVER (PARTITION BY p ORDER BY o) as row_num
+FROM qualify_test 
+QUALIFY row_num = 1;
+```
+
+### 优势对比
+
+| 方面     | 传统方式       | QUALIFY 方式 |
+| -------- | -------------- | ------------ |
+| 代码复杂度 | 高（嵌套子查询） | 低（平铺）     |
+| 可读性   | 一般           | 优秀 ✓       |
+| 代码行数 | 4-5 行         | 3 行         |
+| 性能     | 相当           | 相当         |
+| 维护成本 | 高             | 低 ✓         |
+
+
+
+
+
+## 注意事项
+
+### 必须遵循的规则
+
+* 窗口函数必须在 SELECT 子句中定义并给定别名
+* 在 QUALIFY 子句中使用窗口函数的别名进行条件判断
+* QUALIFY 必须引用至少一个窗口函数

+# 通过嵌套数据类型(Nested Data Types)进行数据转换
+
+## 基本概念
+
+SQL嵌套数据类型（Nested Data Types）允许在表的列中包含复杂的数据结构，如**STRUCT** 和 **ARRAY**。这些数据结构使得表示一对一、多对一以及层次关系变得更加简洁和清晰。
+
+* **STRUCT**: 表示包含多个相关列的单个字段，这些列可以表示对象的属性。
+* **ARRAY**: 表示包含多个结构字段的数组，适用于多对一关系。
+
+## 优势
+
+1. **简化数据模式**：使用STRUCT和ARRAY类型可以简化数据表的模式，使得存储和检索相关列数据更加方便。
+2. **提高查询性能**：嵌套数据类型可以减少表的联接操作，因为相关的数据已经在一个字段中嵌套好。
+3. **增强可读性**：嵌套结构使得数据模式更加直观，开发人员更容易理解和使用。
+4. **灵活的数据处理**：嵌套数据类型支持对复杂对象的灵活操作和排序，以及在数据处理过程中高效拆分和重组数据。
+
+## 使用场景
+
+* **一对一和层次关系**：适用于需要将多个相关字段组合在一起的场景，如用户信息和地址信息的组合。
+
+```sql
+SELECT 
+    c_custkey, 
+    STRUCT(c_name, c_address, c_phone) AS customer_info 
+FROM 
+    clickzetta_sample_data.tpch_100g.customer;
+```
+
+* **多对一关系**：适用于需要在一个字段中存储多个相关对象的场景，如订单和订单项的组合。
+
+```sql
+SELECT 
+    o.o_orderkey, 
+    ARRAY_AGG(STRUCT(o.o_clerk, o.o_totalprice, o.o_orderpriority)) AS items 
+FROM 
+    clickzetta_sample_data.tpch_100g.orders o 
+GROUP BY 
+    o.o_orderkey;
+```
+
+* **数据转换和清洗**：嵌套数据类型可以用于将数据拆分成更小的部分进行转换和清洗，然后再重新组合。
+
+```sql
+-- 使用CTE定义orders_array
+WITH orders_array AS ( 
+    -- 聚合每个客户的所有订单ID到一个数组中
+    SELECT 
+        o_custkey,
+        ARRAY_AGG(o_orderkey) AS order_keys
+    FROM 
+        clickzetta_sample_data.tpch_100g.orders 
+    GROUP BY 
+        o_custkey
+),
+-- 使用CTE定义modified_items
+modified_items AS (
+    -- 使用TRANSFORM函数将每个订单ID加1，生成新的数组
+    SELECT 
+        o_custkey,
+        TRANSFORM(order_keys, x -> x + 1) AS modified_order_keys
+    FROM 
+        orders_array
+)
+-- 主查询部分
+SELECT 
+    c.c_custkey, 
+    mi.modified_order_keys
+FROM 
+    clickzetta_sample_data.tpch_100g.customer c 
+-- 左连接modified_items，依据客户ID（c_custkey）
+LEFT JOIN 
+    modified_items mi
+ON 
+    c.c_custkey = mi.o_custkey;
+```
+
+:-: ![](.topwrite/assets/image_1736846123693.png =798)
+
+使用嵌套数据类型（如STRUCT和ARRAY）来进行数据转换，可以简化数据模式、提高查询性能，并增强数据处理的灵活性和可读性，为复杂数据结构的管理提供了有效的解决方案。
+
+^
+
+## 数据模型
+
+TPC-H 数据代表一个汽车零部件销售商的数据仓库，其中记录了订单、构成订单的项目（lineitem）、供应商、客户、销售的零部件（part）、地区、国家和零部件供应商（partsupp）。
+
+云器Lakehouse内置了共享的TPC-H数据，每个用户可以通过加上数据上下文直接使用，比如：
+
+```sql
+SELECT * FROM 
+clickzetta_sample_data.tpch_100g.customer
+LIMIT 10;
+```
+
+## 通过云器Lakehouse嵌套数据类型进行数据转换
+
+### 有效使用嵌套数据类型
+
+#### 使用 STRUCT 处理一对一和层次关系

+# SQL数据转换基础
+
+SQL数据转换（Data Transformation in SQL）是将数据从一种格式或结构转换为另一种格式或结构的过程。目的是清洗、整合和整形数据，以便其能被有效地存储、分析和利用。
+
+## 基本概念
+
+1. **抽取（Extract**）：从各种数据源（如数据库、文件系统）中提取数据。常见的操作包括数据查询和数据导出。
+2. **转换（Transform**）：对提取的数据进行各种操作以满足目标存储或分析的需求。常见的转换操作包括数据清洗、类型转换、数据聚合等。
+3. **加载（Load**）：将转换后的数据加载到目标存储系统，如数据仓库或数据湖中。
+
+## 常见的数据转换操作
+
+1. **数据清洗**：删除或修正数据中的噪声、重复和错误信息。例如：
+   * 删除空值：`DELETE FROM table_name WHERE column_name IS NULL;`
+   * 修正错误数据：`UPDATE table_name SET column_name = 'Correct Value' WHERE column_name = 'Incorrect Value';`
+
+2. **类型转换**：将数据从一种数据类型转换为另一种。例如：
+   * 将字符串转换为日期：`CAST(column_name AS DATE);`
+   * 将整数转换为字符串：`CAST(column_name AS STRING);`
+
+3. **数据聚合**：对数据进行汇总和统计，例如求和、平均值、计数等。例如：
+   * 计算总和：`SELECT SUM(column_name) FROM table_name;`
+   * 计算平均值：`SELECT AVG(column_name) FROM table_name;`
+
+4. **数据合并**：将来自不同表或数据源的数据进行合并。例如：
+   * 使用连接操作合并数据：`SELECT a.*, b.* FROM table_a a JOIN table_b b ON a.id = b.id;`
+   * 使用联合操作合并数据：`SELECT column_name FROM table_a UNION SELECT column_name FROM table_b;`
+
+5. **数据过滤**：选择符合条件的数据。例如：
+   * 获取特定条件的数据：`SELECT * FROM table_name WHERE column_name = 'value';`
+
+## 数据模型
+
+TPC-H 数据代表一个汽车零部件销售商的数据仓库，其中记录了订单、构成订单的项目（lineitem）、供应商、客户、销售的零部件（part）、地区、国家和零部件供应商（partsupp）。
+
+云器Lakehouse内置了共享的TPC-H数据，每个用户可以通过加上数据上下文直接使用，比如：
+
+```sql
+SELECT * FROM 
+clickzetta_sample_data.tpch_100g.customer
+LIMIT 10;
+```
+
+## 使用场景
+
+1. **数据仓库构建**：在构建数据仓库时，需将数据从不同数据源提取、转换并加载到数据仓库中，确保数据的一致性和高质量。
+2. **商业智能和数据分析**：为了进行商业智能（BI）和数据分析，需对原始数据进行转换，以便分析工具能够高效地解析和展示数据。
+3. **数据迁移**：在数据迁移过程中，需要对数据进行转换，以保证从旧系统到新系统的数据结构和质量一致。
+4. **合规性和数据治理**：确保数据符合行业标准和法规要求，常常需要对数据进行清洗和转换。
+5. **实时数据处理**：在实时数据处理和流数据处理中，对数据进行转换，以便实时分析和决策支持。
+
+SQL数据转换是数据处理中的一个核心环节，能够帮助企业提升数据质量和利用效率，从而支持更好的决策和业务运营。
+
+## 通过云器Lakehouse SQL 进行基本的数据转换
+
+### 获取数据
+
+使用 SELECT...FROM, LIMIT, WHERE, & ORDER BY 从表中读取所需数据。
+
+查询的最常见用途是从表中读取数据。我们可以使用 `SELECT ... FROM` 语句，如下所示。
+
+```sql
+SELECT
+  *
+FROM
+  clickzetta_sample_data.tpch_100g.customer
+LIMIT
+  1;
+```
+
+^
+
+```sql
+-- 使用 * 来指定所有列
+SELECT
+  *
+FROM
+  clickzetta_sample_data.tpch_100g.orders
+LIMIT
+  5;
+```
+
+然而，运行 `SELECT ... FROM` 语句可能会在数据集很大时会出现问题。
+
+```sql
+-- 只使用列名来读取这些列的数据
+SELECT
+  o_orderkey,
+  o_totalprice
+FROM
+  clickzetta_sample_data.tpch_100g.orders
+LIMIT
+  5;
+```
+
+如果我们想获取符合特定条件的行，可以使用 `WHERE` 子句。我们可以在 `WHERE` 子句中指定一个或多个过滤条件。
+
+`WHERE` 子句可以使用 `AND` 和 `OR` 条件组合多个过滤条件，如下所示。
+
+```sql
+-- 所有 c_nationkey = 20 的客户行
+SELECT
+  *
+FROM
+  clickzetta_sample_data.tpch_100g.customer
+WHERE
+  c_nationkey = 20
+LIMIT
+  10;
+```
+
+^
+
+```sql
+-- 所有 c_nationkey = 20 且 c_acctbal > 1000 的客户行
+SELECT
+  *
+FROM
+  clickzetta_sample_data.tpch_100g.customer
+WHERE
+  c_nationkey = 20
+  AND c_acctbal > 1000
+LIMIT
+  10;
+```
+
+```sql
+-- 所有 c_nationkey = 20 或 c_acctbal > 1000 的客户行
+SELECT
+  *
+FROM
+  clickzetta_sample_data.tpch_100g.customer
+WHERE
+  c_nationkey = 20
+  OR c_acctbal > 1000
+LIMIT
+  10;
+```
+
+```sql
+-- 所有 (c_nationkey = 20 且 c_acctbal > 1000) 或 c_nationkey = 11 的客户行
+SELECT
+  *
+FROM
+  clickzetta_sample_data.tpch_100g.customer
+WHERE
+  (
+    c_nationkey = 20
+    AND c_acctbal > 1000
+  )
+  OR c_nationkey = 11
+LIMIT
+  10;
+```
+
+我们可以组合多个过滤条件，如上所示。我们已经看到了等于 (`=`) 和大于 (`>`) 条件运算符。共有 6 个 **条件运算符**，它们是：
+
+1. < 小于
+2. \> 大于
+3. <= 小于或等于
+4. \>= 大于或等于
+5. \= 等于
+6. <> 和 != 都表示不等于（某些数据库只支持其中一个）
+
+此外，对于字符串类型，我们可以使用 `like` 条件进行 **模式匹配**。在 `like` 条件中，`_` 表示任意单个字符，`%` 表示零个或多个字符，例如。
+
+```sql
+-- 所有 c_name 包含 381 的客户行
+SELECT
+  *
+FROM
+  clickzetta_sample_data.tpch_100g.customer
+WHERE
+  c_name LIKE '%381%';
+```
+
+^
+
+```sql
+-- 所有 c_name 包含任意字符、9 和 1 的客户行
+SELECT
+  *
+FROM
+  clickzetta_sample_data.tpch_100g.customer
+WHERE
+  c_name LIKE '%_91%';
+```
+
+我们还可以使用 `IN` 和 `NOT IN` 来过滤多个值。
+
+^
+
+```sql
+-- 所有 c_nationkey = 10 或 c_nationkey = 20 的客户行
+SELECT
+  *
+FROM
+  clickzetta_sample_data.tpch_100g.customer
+WHERE
+  c_nationkey IN (10, 20);
+```
+
+可以使用 `count(*)` 来获取表中的行数，如下所示。
+
+^
+
+```sql
+SELECT
+  COUNT(*)
+FROM
+  clickzetta_sample_data.tpch_100g.lineitem;
+```
+
+^
+
+```sql
+SELECT  COUNT(*)FROM  clickzetta_sample_data.tpch_100g.lineitem;
+```
+
+如果我们想按特定列的值对行进行排序，可以使用 `ORDER BY`，例如。
+
+^
+
+```sql
+-- 显示 custkey 最小的前十个客户记录
+-- 行默认按升序排序
+SELECT
+  *
+FROM
+  clickzetta_sample_data.tpch_100g.orders
+ORDER BY
+  o_custkey
+LIMIT
+  10;
+```
+
+### 连接Join
+
+使用 JOINs 结合多个表的数据（有不同类型的 JOINs）。
+
+我们可以使用连接来结合多个表的数据。编写连接查询时，格式如下所示。
+
+^
+
+```sql
+-- 基于非真实表
+SELECT
+    a.*
+FROM
+    table_a a -- 左表 a
+    JOIN table_b b -- 右表 b
+    ON a.id = b.id
+```
+
+首先指定的表（table\_a）是左表，而第二个指定的表是右表。当有多个表连接时，我们将前两个表的连接数据集视为左表，第三个表视为右表（数据库会优化连接以提高性能）。
+
+^
+
+```sql
+-- 基于非真实表
+SELECT
+    a.*
+FROM
+    table_a a -- 左表 a
+    JOIN table_b b -- 右表 b
+    ON a.id = b.id
+    JOIN table_c c -- 左表是 table_a 和 table_b 的连接数据，右表是 table_c
+    ON a.c_id = c.id
+```
+
+主要有五种连接类型，它们是：
+
+#### 1. 内连接（默认）：仅获取两个表中都存在的行
+
+^
+
+```sql
+SELECT
+  o.o_orderkey,
+  l.l_orderkey
+FROM
+  clickzetta_sample_data.tpch_100g.orders o
+  JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
+  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY
+LIMIT
+  100;
+```
+
+^
+
+```sql
+SELECT
+  COUNT(o.o_orderkey) AS order_rows_count,
+  COUNT(l.l_orderkey) AS lineitem_rows_count
+FROM
+  clickzetta_sample_data.tpch_100g.orders o
+  JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
+  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY;
+```
+
+**注意**：连接默认为内连接。
+
+输出将包含订单和行项目中至少找到一个匹配行的记录（相同的 o\_orderkey 且订单日期在发货日期前后 5 天内）。
+
+我们还可以看到订单和行项目表中有24792743行匹配。
+
+#### 2. 左外连接（又称左连接）：获取左表的所有行和右表的匹配行
+
+```sql
+SELECT
+  o.o_orderkey,
+  l.l_orderkey
+FROM
+  clickzetta_sample_data.tpch_100g.orders o
+  LEFT JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
+  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY
+LIMIT
+  100;
+```
+
+^
+
+```sql
+SELECT
+  COUNT(o.o_orderkey) AS order_rows_count,
+  COUNT(l.l_orderkey) AS lineitem_rows_count
+FROM
+  clickzetta_sample_data.tpch_100g.orders o
+  LEFT JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
+  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY;
+```
+
+输出将包含订单表的所有行和行项目表中至少找到一个匹配行的记录（相同的 o\_orderkey 且订单日期在发货日期前后 5 天内）。
+
+我们还可以看到订单表有 151947677 行，行项目表有24792743 行。订单表的行数为 1,500,000，但由于连接条件，产生了 151947677 行，因为一些订单与多个行项目匹配。
+
+#### 3. 右外连接（又称右连接）：获取左表的匹配行和右表的所有行
+
+```sql
+SELECT
+  o.o_orderkey,
+  l.l_orderkey
+FROM
+  clickzetta_sample_data.tpch_100g.orders o
+  RIGHT JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
+  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY
+LIMIT
+  100;
+```
+
+^
+
+```sql
+SELECT
+  COUNT(o.o_orderkey) AS order_rows_count,
+  COUNT(l.l_orderkey) AS lineitem_rows_count
+FROM
+  clickzetta_sample_data.tpch_100g.orders o
+  RIGHT JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
+  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY;
+```
+
+输出将包含订单表中至少找到一个匹配行的记录（相同的 o\_orderkey 且订单日期在发货日期前后 5 天内）和行项目表的所有行。
+
+我们还可以看到订单表有 24792743 行，行项目表有 600037902 行。
+
+#### 4. 全外连接：获取左表和右表的所有行
+
+```sql
+SELECT
+  o.o_orderkey,
+  l.l_orderkey
+FROM
+  clickzetta_sample_data.tpch_100g.orders o
+  FULL OUTER JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
+  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY
+LIMIT
+  100;
+```
+
+^
+
+```sql
+SELECT
+  COUNT(o.o_orderkey) AS order_rows_count,
+  COUNT(l.l_orderkey) AS lineitem_rows_count
+FROM
+  clickzetta_sample_data.tpch_100g.orders o
+  FULL OUTER JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
+  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY;
+```
+
+输出将包含订单表中至少找到一个匹配行的记录（相同的 o\_orderkey 且订单日期在发货日期前后 5 天内）和行项目表的所有行。
+
+我们还可以看到订单表有 151947677 行，行项目表有 600037902 行。
+
+#### 5. 交叉连接：获取所有行的笛卡尔积
+
+```sql
+SELECT
+  n.n_name AS nation_c_name,
+  r.r_name AS region_c_name
+FROM
+  clickzetta_sample_data.tpch_100g.nation n
+  CROSS JOIN clickzetta_sample_data.tpch_100g.region r;
+```
+
+输出将包含国家表的每一行与地区表的每一行的连接。共有 25 个国家和 5 个地区，因此交叉连接的结果有 125 行。
+
+^
+
+有时我们需要将表与自身连接，称为自连接。
+
+**示例**：
+
+1. 对于每个客户订单，获取同一周（周日 - 周六，不是前七天）内较早放置的订单。仅显示至少有一个此类订单的客户订单。
+
+```sql
+SELECT
+  o1.o_custkey
+FROM
+  clickzetta_sample_data.tpch_100g.orders o1
+  JOIN clickzetta_sample_data.tpch_100g.orders o2 ON o1.o_custkey = o2.o_custkey
+  AND YEAR (o1.o_orderdate) = YEAR (o2.o_orderdate)
+  AND week (o1.o_orderdate) = week (o2.o_orderdate)
+WHERE
+  o1.o_orderkey != o2.o_orderkey;
+```
+
+大多数分析查询需要计算涉及多个行的数据指标。`GROUP BY` 允许我们对基于指定列值分组的行集进行聚合计算。
+
+**示例**：
+
+1. 创建一个报告，显示每个订单优先级段的订单数量。
+
+```sql
+SELECT
+  o_orderpriority,
+  COUNT(*) AS num_orders
+FROM
+  clickzetta_sample_data.tpch_100g.orders
+GROUP BY
+  o_orderpriority;
+```
+
+在上述查询中，我们按 `orderpriority` 分组，`count(*)` 计算将应用于具有特定 `orderpriority` 值的行。输出将包含每个唯一 `orderpriority` 值的一行和 `count(*)` 计算。
+
+^
+
+允许的计算通常是 SUM/MIN/MAX/AVG/COUNT。然而，某些数据库有更复杂的聚合函数；请查阅您的数据库文档。
+
+### 子查询
+
+使用子查询在查询中使用查询结果。
+
+当我们想将一个查询的结果作为另一个查询的表时，我们使用子查询。**示例**：
+
+1. 创建一个报告，显示国家、该国供应的项目数量（由该国的供应商供应）以及该国购买的项目数量（由该国的客户购买）。
+
+```sql
+SELECT
+  n.n_name AS nation_c_name,
+  s.quantity AS supplied_items_quantity,
+  c.quantity AS purchased_items_quantity
+FROM
+  clickzetta_sample_data.tpch_100g.nation n
+  LEFT JOIN (
+    SELECT
+      n.n_nationkey,
+      SUM(l.l_quantity) AS quantity
+    FROM
+      clickzetta_sample_data.tpch_100g.lineitem l
+      JOIN clickzetta_sample_data.tpch_100g.supplier s ON l.l_suppkey = s.s_suppkey
+      JOIN clickzetta_sample_data.tpch_100g.nation n ON s.s_nationkey = n.n_nationkey
+    GROUP BY
+      n.n_nationkey
+  ) s ON n.n_nationkey = s.n_nationkey
+  LEFT JOIN (
+    SELECT
+      n.n_nationkey,
+      SUM(l.l_quantity) AS quantity
+    FROM
+      clickzetta_sample_data.tpch_100g.lineitem l
+      JOIN clickzetta_sample_data.tpch_100g.orders o ON l.l_orderkey = o.o_orderkey
+      JOIN clickzetta_sample_data.tpch_100g.customer c ON o.o_custkey = c.c_custkey
+      JOIN clickzetta_sample_data.tpch_100g.nation n ON c.c_nationkey = n.n_nationkey
+    GROUP BY
+      n.n_nationkey
+  ) c ON n.n_nationkey = c.n_nationkey;
+```
+
+在上述查询中，我们可以看到有两个子查询，一个用于计算一个国家供应的项目数量，另一个用于计算该国客户购买的项目数量。
+
+### CASE WHEN&#x20;
+
+使用 CASE 语句复制 IF.ELSE 逻辑。
+
+我们可以在查询的 `SELECT ... FROM` 部分进行条件逻辑，如下所示。
+
+```sql
+SELECT
+    o_orderkey,
+    o_totalprice,
+    CASE
+        WHEN o_totalprice > 100000 THEN 'high'
+        WHEN o_totalprice BETWEEN 25000
+        AND 100000 THEN 'medium'
+        ELSE 'low'
+    END AS order_price_bucket
+FROM
+    clickzetta_sample_data.tpch_100g.orders;
+```
+
+我们可以看到如何根据 `totalprice` 列显示不同的值。我们还可以使用多个条件作为我们的条件标准（例如，totalprice > 100000 AND orderpriority = '2-HIGH'）。
+
+### 标准函数
+
+使用标准内置数据库函数进行常见的字符串、时间和数字数据操作。
+
+在处理数据时，我们通常需要更改列中的值；以下是一些需要了解的标准函数：
+
+1. **字符串函数**
+
+   1. **LENGTH** 用于计算字符串的长度。例如，`SELECT LENGTH('hi');` 将输出 2。
+   2. **CONCAT** 将多个字符串列合并为一个。例如，`SELECT CONCAT(o_orderstatus, '-', o_orderpriority) FROM clickzetta_sample_data.tpch_100g.orders LIMIT 5;` 将连接 o\_orderstatus 和 o\_orderpriority 列，中间用短横线分隔。
+   3. **SPLIT** 用于根据给定的分隔符将值拆分为数组。例如，`SELECT STRING_SPLIT(o_orderpriority, '-') FROM clickzetta_sample_data.tpch_100g.orders LIMIT 5;` 将输出一个列，其中的数组是通过在 `-` 处拆分 o\_orderpriority 值形成的。
+   4. **SUBSTRING** 用于从值中获取子字符串，给定起始和结束字符索引。例如，`SELECT o_orderpriority, SUBSTRING(o_orderpriority, 1, 5) FROM clickzetta_sample_data.tpch_100g.orders LIMIT 5;` 将获取 o\_orderpriority 列的前五个（1 - 5）字符。
+   5. **TRIM** 用于删除值左右两侧的空格。例如，`SELECT TRIM(' hi ');` 将输出 `hi`，周围没有空格。LTRIM 和 RTRIM 类似，但分别只删除字符串前后的空格。
+
+2. **日期和时间函数**
+
+   1. **添加和减去日期**：用于添加和减去时间段；格式在很大程度上取决于数据库。在 Lakehouse 中，`datediff` 接受 3 个参数，输出单位（天、月、年），日期/时间值 a 和 b，使得输出为 a - b。`+ INTERVAL n UNIT(DAY/MONTH/YEAR)` 将指定单位的值添加到时间戳值中。
+
+      ```sql
+        -- 日期和时间函数
+        SELECT
+            datediff(day, DATE '2022-10-01', DATE '2023-11-05') AS diff_in_days,
+            datediff(month, DATE '2022-10-01', DATE '2023-11-05') AS diff_in_months,
+            datediff(year, DATE '2022-10-01', DATE '2023-11-05') AS diff_in_years,
+            DATE '2022-10-01' + INTERVAL 400 DAY AS new_date;
+      ```
+
+   它将显示两个日期之间指定时间段的差异。我们还可以从日期/时间列中添加/减去任意时间段。例如，`SELECT DATE '2022-11-05' + INTERVAL '10' DAY;` 将显示输出 `2022-11-15`（尝试日期减法）。
+
+   ^
+
+3. **字符串 <=> 日期/时间转换**
+
+当我们想将字符串的数据类型更改为日期/时间时，我们可以使用 `DATE 'YYYY-MM-DD'` 或 `TIMESTAMP 'YYYY-MM-DD HH:mm:SS'` 函数。但如果数据是非标准日期/时间格式，如 `MM/DD/YYYY`，我们需要指定输入结构；我们使用 `date\_format` 来实现这一点，例如：
+
+```sql
+SELECT date_format('2023-05-11', 'M-d-y');
+```
+
+我们可以使用 `date_format` 将时间戳/日期转换为所需格式的字符串。例如：
+
+```sql
+SELECT date_format(o_orderdate, 'yyyy-MM-01') AS first_month_date FROM clickzetta_sample_data.tpch_100g.orders LIMIT 5;
+```
+
+请参阅 [此页面](sql_functions/scalar_functions/datetime_functions/date_format.md) 了解如何设置正确的日期时间格式。
+
+4. **时间框架函数（YEAR/MONTH/DAY**）：当我们想从日期/时间列中提取特定时间段时，我们可以使用这些函数。例如，`SELECT year(DATE '2023-11-05');` 将返回 2023。类似地，我们还有 month、day、hour、min 等。
+
+请参阅 [此页面](time-function.md) 了解更多的时间函数。
+
+5. **数字**
+
+   1. **ROUND** 用于指定小数点后允许的位数。例如，`SELECT ROUND(100.102345, 2);`
+   2. **ABS** 用于获取给定数字的绝对值。例如，`SELECT ABS(-100), ABS(100);`
+   3. **数学运算** 例如， +,-,\*,/。
+   4. **Ceil/Floor** 用于获取给定小数的下一个更高和最近的较低整数。例如，`SELECT CEIL(100.1), FLOOR(100.1);`

+# 通过CTE进行数据转换
+
+让我们先了解一下使用Lakehouse SQL的[公用表表达式（Common Table Expression, CTE）](WITH.md)进行数据转换的基本概念、优势以及常见的使用场景。
+
+## 基本概念
+
+公用表表达式（CTE）是一种可以在SQL查询中定义临时结果集的表达式。该结果集在查询的执行过程中存在，通常用于简化复杂查询、递归查询或分解查询步骤。CTE通常由[WITH关键字](WITH.md)引入，并可以在随后的`SELECT`、`INSERT`、`UPDATE`和`DELETE`语句中使用。
+
+基本语法：
+
+```sql
+WITH cte_name AS (
+    SELECT column1, column2, ...
+    FROM table_name
+    WHERE condition
+)
+SELECT * FROM cte_name;
+```
+
+## 优势
+
+1. **可读性高**：CTE可以使复杂查询更具可读性和可维护性。通过将复杂的查询逻辑拆解为多个可理解的部分，CTE增强了查询的结构化和清晰度。CTE 使测试复杂查询更简单
+
+   * CTE 是一个可以在单个查询中重用的 `SELECT` 语句。
+   * 复杂的 SQL 查询通常涉及多个子查询。多个子查询会使代码难以阅读。
+   * 使用公共表表达式（CTE）可以使你的查询更易读。
+
+2. **复用性强**：CTE可以在同一查询中多次引用，从而避免重复代码，提高查询的复用性。
+
+3. **步骤化数据转换**：CTE可以将数据转换过程分步骤实现，每个步骤都可以定义为一个独立的CTE，这样便于调试和测试。
+
+## 使用场景
+
+以下是一些利用CTE进行数据转换的常见场景：
+
+### 1. 数据清洗和转换
+
+通过CTE可以分步骤清洗和转换数据，例如去除重复值、修正数据格式：
+
+```sql
+WITH cleaned_data AS (
+    SELECT DISTINCT column1, column2
+    FROM raw_table
+    WHERE column1 IS NOT NULL
+),
+transformed_data AS (
+    SELECT column1, UPPER(column2) AS transformed_column2
+    FROM cleaned_data
+)
+SELECT * FROM transformed_data;
+```
+
+### 2. 分组和聚合
+
+CTE可以用于进行复杂的分组和聚合操作，并在后续查询中引用聚合结果：
+
+```sql
+WITH total_sales AS (
+    SELECT customer_id, SUM(order_amount) AS total_spent
+    FROM orders
+    GROUP BY customer_id
+)
+SELECT customer_id, total_spent
+FROM total_sales
+WHERE total_spent > 1000;
+```
+
+### 3. 数据合并和连接
+
+使用CTE，可以简化多表连接和数据合并操作：
+
+```sql
+WITH customer_orders AS (
+    SELECT c.customer_id, c.customer_name, o.order_id, o.order_date
+    FROM customers c
+    JOIN orders o ON c.customer_id = o.customer_id
+)
+SELECT *
+FROM customer_orders
+WHERE order_date > '2024-01-01';
+```
+
+## 数据模型
+
+TPC-H 数据代表一个汽车零部件销售商的数据仓库，其中记录了订单、构成订单的项目（lineitem）、供应商、客户、销售的零部件（part）、地区、国家和零部件供应商（partsupp）。
+
+云器Lakehouse内置了共享的TPC-H数据，每个用户可以通过加上数据上下文直接使用，比如：
+
+```sql
+SELECT * FROM 
+clickzetta_sample_data.tpch_100g.customer
+LIMIT 10;
+```
+
+## 通过云器Lakehouse SQL CTE进行数据转换
+
+### 如何定义 CTE
+
+```sql
+-- CTE 定义
+WITH
+  supplier_nation_metrics AS ( -- 使用 WITH 关键字定义 CTE 1
+    SELECT
+      n.n_nationkey,
+      SUM(l.l_QUANTITY) AS num_supplied_parts
+    FROM
+      clickzetta_sample_data.tpch_100g.lineitem l
+      JOIN clickzetta_sample_data.tpch_100g.supplier s ON l.l_suppkey = s.s_suppkey
+      JOIN clickzetta_sample_data.tpch_100g.nation n ON s.s_nationkey = n.n_nationkey
+    GROUP BY
+      n.n_nationkey
+  ),
+  buyer_nation_metrics AS ( -- 定义 CTE 2
+    SELECT
+      n.n_nationkey,
+      SUM(l.l_QUANTITY) AS num_purchased_parts
+    FROM
+      clickzetta_sample_data.tpch_100g.lineitem l
+      JOIN clickzetta_sample_data.tpch_100g.orders o ON l.l_orderkey = o.o_orderkey
+      JOIN clickzetta_sample_data.tpch_100g.customer c ON o.o_custkey = c.c_custkey
+      JOIN clickzetta_sample_data.tpch_100g.nation n ON c.c_nationkey = n.n_nationkey
+    GROUP BY
+      n.n_nationkey
+  )
+SELECT -- 最终的 SELECT 语句前不需要逗号
+  n.n_name AS nation_name,
+  s.num_supplied_parts,
+  b.num_purchased_parts
+FROM
+  clickzetta_sample_data.tpch_100g.nation n
+  LEFT JOIN supplier_nation_metrics s ON n.n_nationkey = s.n_nationkey
+  LEFT JOIN buyer_nation_metrics b ON n.n_nationkey = b.n_nationkey
+LIMIT 10;
+```
+
+### 计算因折扣而损失的金额
+
+使用 `lineitem` 表获取订单中项目的价格（不含折扣），并与订单进行比较。先确定比较需要进行的粒度。分步骤思考，即先获取订单中所有项目的不含折扣的价格，然后将其与已计算折扣的 `totalprice` 的订单数据进行比较。
+
+```sql
+WITH lineitem_agg AS (
+    SELECT 
+        l_orderkey,
+        SUM(l_extendedprice) AS total_price_without_discount
+    FROM 
+        clickzetta_sample_data.tpch_100g.lineitem
+    GROUP BY 
+        l_orderkey
+)
+SELECT 
+    o.o_orderkey,
+    o.o_totalprice, 
+    l.total_price_without_discount - o.o_totalprice AS amount_lost_to_discount
+FROM 
+    clickzetta_sample_data.tpch_100g.orders o
+JOIN 
+    lineitem_agg l ON o.o_orderkey = l.l_orderkey
+ORDER BY 
+    o.o_orderkey;
+```
+
+### 不要过度使用 CTE。注意代码的可读性。
+
+1. CTE 可以帮助提高查询的可读性和可重用性。
+
+2. 不要过度使用 CTE；注意查询的大小。
+
+   * 多个临时表的 SQL 查询比带有众多 CTE 的 1000 行 SQL 查询更好。
+   * 保持每个查询中的 CTE 数量较小（取决于查询的大小，但通常 < 5）。
+
+3. 如果对CTE 的性有疑问，请检查你的查询计划。

+2. [公共表表达式 (CTE)](sql_data_transform_cte.md)
+3. [窗口函数](sql_data_transform_windows.md)
+4. [嵌套数据类型](sql_data_transfom_NestedDataTypes.md)
+
+## 1. 常见数据处理场景的实用函数
+
+### 1.1. 需要分区中的第一/最后一行时使用 ROW\_NUMBER
+
+```sql
+SELECT 
+    o_custkey, 
+    o_orderdate, 
+    o_totalprice
+FROM (
+    SELECT 
+        o_custkey, 
+        o_orderdate, 
+        o_totalprice,
+        ROW_NUMBER() OVER (PARTITION BY o_custkey ORDER BY o_orderdate DESC) AS rn
+    FROM clickzetta_sample_data.tpch_100g.orders
+) t
+WHERE rn = 1;
+```
+
+### 1.2. STRUCT 数据类型按其键从左到右排序
+
+```sql
+WITH order_struct AS (
+    SELECT 
+        o_orderkey,
+        struct(o_orderdate, o_totalprice, o_orderkey) AS order_info
+    FROM clickzetta_sample_data.tpch_100g.orders
+)
+SELECT 
+    MIN(order_info) AS min_order_date,
+    MAX(order_info) AS max_order_date_price
+FROM order_struct;
+```
+
+### 1.3. 使用 BOOL\_OR 和 BOOL\_AND 分别检查至少一个或所有布尔值是否为真
+
+```sql
+SELECT 
+    o_custkey, 
+    BOOL_OR(o_shippriority > 0) AS has_atleast_one_priority_order,
+    BOOL_AND(o_shippriority > 0) AS has_all_priority_order
+FROM clickzetta_sample_data.tpch_100g.orders
+GROUP BY o_custkey;
+```
+
+### 1.4. 想要选择除少数列之外的所有列时使用 EXCEPT
+
+```sql
+SELECT * EXCEPT(o_orderdate, o_totalprice)
+FROM clickzetta_sample_data.tpch_100g.orders;
+```
+
+### 1.5. 厌倦了在 GROUP BY 中创建长长的列列表时使用 GROUP BY ALL
+
+```sql
+SELECT 
+    o_orderkey, 
+    o_custkey, 
+    o_orderstatus, 
+    SUM(o_totalprice) AS total_price
+FROM clickzetta_sample_data.tpch_100g.orders
+GROUP BY ALL;
+```
+
+### 1.6. ORDER、GROUP字段用SELECT字段的序号代替
+
+```sql
+SELECT 
+    o_orderkey, 
+    o_custkey, 
+    o_orderstatus, 
+    SUM(o_totalprice) AS total_price
+FROM clickzetta_sample_data.tpch_100g.orders
+GROUP BY 1,2,3
+ORDER BY 3,2,1;
+```
+
+### 1.7. 需要仅在满足特定条件时计数行时使用 COUNT IF
+
+```sql
+SELECT 
+    o_custkey, 
+    COUNT_IF(o_totalprice > 100000) AS high_value_orders,
+    COUNT(o_totalprice) as all_orders
+FROM clickzetta_sample_data.tpch_100g.orders
+GROUP BY o_custkey;
+```
+
+### 1.8. 使用 COALESCE 处理空列值与其他列或回退值
+
+```sql
+WITH fake_orders AS (
+    SELECT 1 AS o_orderkey, 100 AS o_totalprice, NULL AS discount
+    UNION ALL
+    SELECT 2 AS o_orderkey, 200 AS o_totalprice, 20 AS discount
+    UNION ALL
+    SELECT 3 AS o_orderkey, 300 AS o_totalprice, NULL AS discount
+)
+SELECT 
+    o_orderkey, 
+    o_totalprice, 
+    discount,
+    COALESCE(discount, o_totalprice * 0.10) AS final_discount
+FROM fake_orders;
+```
+
+### 1.9. 使用 sequence和explode 生成数字/日期行范围
+
+```sql
+SELECT explode(sequence(1, 10)) AS num;
+```
+
+^
+
+```sql
+SELECT    EXPLODE (
+          sequence(
+          to_date('2024-01-01'),
+          to_date('2024-01-10'),
+          interval 1 DAY
+          )
+          ) AS date;
+```
+
+### 1.10. 使用 UNNEST 将 ARRAY/LIST 元素转换为单独的行
+
+```sql
+WITH nested_data AS (
+    SELECT 1 AS id, array(10, 20, 30) AS values
+    UNION ALL
+    SELECT 2 AS id, array(40, 50) AS values
+)
+SELECT 
+    id, 
+    unnest(values) AS flattened_value
+FROM nested_data;
+```
+
+## 2. 另一个表中的存在/不存在的数据获取
+
+### 2.1. 根据另一个表中的数据存在性获取表中的数据时使用 EXISTS
+
+```sql
+SELECT 
+    c_custkey, 
+    c_name
+FROM clickzetta_sample_data.tpch_100g.customer c
+WHERE EXISTS (
+    SELECT o_orderkey
+    FROM clickzetta_sample_data.tpch_100g.orders o
+    WHERE o.o_custkey = c.c_custkey AND o.o_totalprice > 1000
+);
+```
+
+### 2.2. 获取两个表中都存在的数据时使用 INTERSECT
+
+```sql
+SELECT    c_custkey
+FROM      clickzetta_sample_data.tpch_100g.customer
+INTERSECT
+SELECT    o_custkey
+FROM      clickzetta_sample_data.tpch_100g.orders;
+```
+
+### 2.3. 获取表 1 中存在但表 2 中不存在的数据时使用 EXCEPT
+
+```sql
+SELECT c_custkey
+FROM clickzetta_sample_data.tpch_100g.customer
+EXCEPT
+SELECT o_custkey
+FROM clickzetta_sample_data.tpch_100g.orders;
+```
+
+### 2.4. 获取数据差异（即 delta），使用 (A - B) U (B - A)
+
+```sql
+SELECT c_custkey, 'DELETED' as ops FROM ( 
+SELECT c_custkey
+FROM clickzetta_sample_data.tpch_100g.customer
+EXCEPT
+SELECT c_custkey
+FROM clickzetta_sample_data.tpch_100g.customer
+)
+
+UNION ALL
+
+SELECT c_custkey, 'UPSERTED' as ops FROM ( 
+SELECT c_custkey, c_name, c_address
+FROM clickzetta_sample_data.tpch_100g.customer
+EXCEPT
+SELECT c_custkey, c_name, c_address
+FROM clickzetta_sample_data.tpch_100g.customer
+);
+```
+
+## 3. 在 SQL 中CASE 语句
+
+### 3.1. 使用 CASE 语句
+
+```sql
+SELECT 
+    o_orderkey, 
+    o_totalprice,
+    CASE
+        WHEN o_totalprice > 100000 THEN 'Large Order'
+        ELSE 'Regular Order'
+    END AS order_type
+FROM clickzetta_sample_data.tpch_100g.orders
+LIMIT 5;
+```
+
+## 4. 访问关于数据的元数据
+
+### 4.1. 访问在 information\_schema 中存储的元数据
+
+```sql
+-- 查看表的信息
+DESCRIBE TABLE clickzetta_sample_data.tpch_100g.orders;
+```
+
+```sql
+-- 查看所有表
+SHOW TABLES IN clickzetta_sample_data.tpch_100g;
+```
+
+^
+
+## 5. 使用 UPSERTS（即 MERGE INTO）避免数据重复
+
+### 5.1. 使用 UPSERT/MERGE INTO 插入新数据，更新现有数据
+
+```sql
+MERGE INTO dim_customer_scd2 AS target
+USING (
+    VALUES
+        (1, 'Customer#000000001', 'New Address 1', 15, '25-989-741-2988', 711.56, 'BUILDING', 'comment1', '2024-10-18', NULL, TRUE),
+        (2, 'Customer#000000002', 'New Address 2', 18, '12-423-790-3665', 879.49, 'FURNITURE', 'comment2', '2024-10-18', NULL, TRUE),
+        (1501, 'Customer#000001501', 'New Address 1501', 24, '11-345-678-9012', 500.50, 'MACHINERY', 'comment1501', '2024-10-18', NULL, TRUE),
+        (1502, 'Customer#000001502', 'New Address 1502', 21, '22-456-789-0123', 600.75, 'AUTOMOBILE', 'comment1502', '2024-10-18', NULL, TRUE)
+) AS source (c_custkey, c_name, c_address, c_nationkey, c_phone, c_acctbal, c_mktsegment, c_comment, valid_from, valid_to, is_current)
+ON target.c_custkey = source.c_custkey
+WHEN MATCHED AND target.is_current = TRUE THEN
+    UPDATE SET valid_to = source.valid_from, is_current = FALSE
+WHEN NOT MATCHED THEN
+    INSERT (c_custkey, c_name, c_address, c_nationkey, c_phone, c_acctbal, c_mktsegment, c_comment, valid_from, valid_to, is_current)
+    VALUES (source.c_custkey, source.c_name, source.c_address, source.c_nationkey, source.c_phone, source.c_acctbal, source.c_mktsegment, source.c_comment, source.valid_from, source.valid_to, source.is_current);
+```
+
+## 6. 高级 JOIN 类型
+
+### 6.1. 使用JOIN和ROW\_NUMBER获取表 2 中与表 1 行时间最接近的值
+
+```sql
+WITH stock_prices_data AS (
+    SELECT 'APPL' AS ticker, to_timestamp('2001-01-01 00:00:00') AS ts, 1 AS price

+)
+SELECT h.ticker,
+    h.ts AS holdings_ts,
+    p.ts AS stock_price_ts,
+    p.price,
+    h.shares,
+    p.price * h.shares AS value
+FROM portfolio_holdings_data h
+JOIN (
+    SELECT 
+        ticker, 
+        ts, 
+        price,
+        ROW_NUMBER() OVER (PARTITION BY ticker ORDER BY ts DESC) AS rn
+    FROM stock_prices_data
+) p
+ON h.ticker = p.ticker AND h.ts >= p.ts
+WHERE p.rn = 1
+ORDER BY h.ticker, h.ts;
+```
+
+### 6.2. 使用 ANTI JOIN 获取表 1 中存在但表 2 中不存在的行
+
+```sql
+SELECT    c.c_custkey
+FROM      clickzetta_sample_data.tpch_100g.customer c
+LEFT      ANTI JOIN clickzetta_sample_data.tpch_100g.orders o ON c.c_custkey = o.o_custkey
+ORDER BY  c.c_custkey
+LIMIT     5;
+```
+
+### 6.3. 使用 LATERAL JOIN 对表 1 中的每一行连接表 2 中的所有“匹配”行
+
+```sql
+SELECT    o.o_orderkey,
+          o.o_totalprice,
+          l.l_linenumber,
+          l.l_extendedprice
+FROM      clickzetta_sample_data.tpch_100g.orders o
+CROSS     JOIN clickzetta_sample_data.tpch_100g.lineitem l
+WHERE     l.l_orderkey = o.o_orderkey AND      
+          l.l_linenumber <= 2 AND      
+          l.l_extendedprice < (o.o_totalprice / 2)
+ORDER BY  o.o_orderkey,
+          l.l_linenumber;
+```
+
+## 7 业务用例
+
+### 7.1. 使用 CASE和 `GROUP BY `将维度值转换为单独的列
+
+```sql
+SELECT    o_custkey,
+          SUM(
+          CASE
+                    WHEN o_orderstatus = 'F' THEN o_totalprice
+                    ELSE 0
+          END
+          ) AS fulfilled_total,
+          SUM(
+          CASE
+                    WHEN o_orderstatus = 'O' THEN o_totalprice
+                    ELSE 0
+          END
+          ) AS open_total,
+          SUM(
+          CASE
+                    WHEN o_orderstatus = 'P' THEN o_totalprice
+                    ELSE 0
+          END
+          ) AS pending_total
+FROM      clickzetta_sample_data.tpch_100g.orders
+GROUP BY  o_custkey
+ORDER BY  o_custkey;
+```
+
+### 7.2. 使用 CUBE 生成每个可能维度组合的指标
+
+```sql
+SELECT    o_orderpriority,

+# 通过窗口函数（Windows）进行数据转换
+
+我们先了解一下在 ETL/ELT（Extract, Transform, Load）过程中使用窗口函数进行数据转换的基本概念和常见使用场景。
+
+## 基本概念
+
+[窗口函数](window-function-summary.md)是SQL中专门用于在指定的数据集合（即“窗口”）中执行复杂多行操作的一类函数。窗口函数可以保留行级别详细信息，同时在特定数据窗口内部执行计算。
+
+[基本语法](windowframe.md)：
+
+```sql
+窗口函数() OVER (PARTITION BY column_name ORDER BY column_name)
+```
+
+* **OVER** 关键字定义了窗口的范围。
+
+* **PARTITION BY** 定义了如何划分数据分区，在每个分区内应用窗口函数。如果没有指定分区，则整个表被视为一个分区。
+
+* **函数** 应用于当前行的函数。函数结果在输出中添加一个额外的列。
+
+* **ORDER BY** 定义了窗口内的排序方式。
+
+## 常见窗口函数
+
+1. [RANK()](sql_functions/window_functions/rank.md)：排序函数，为每个分区的每个行分配一个排名。
+2. [DENSE\_RANK()](sql_functions/window_functions/dense_rank.md)：类似于 RANK()，但不会跳过排名。
+3. [ROW\_NUMBER()](sql_functions/window_functions/row_number.md)：为每个分区的行分配唯一编号。
+4. [SUM()](sql_functions/window_functions/sum.md)：累计求和。
+5. [AVG()](sql_functions/window_functions/avg.md)：计算平均。
+6. [LAG()](sql_functions/window_functions/lag.md)：向前获取某行的数据。
+7. [LEAD()](sql_functions/window_functions/lead.md)：向后获取某行的数据。
+
+## 使用场景
+
+### 1. 数据去重和标记
+
+窗口函数常用于数据去重，标记重复行。
+
+**前提条件**：表中需要有**唯一标识符**（如自增 ID、UUID 或业务主键），用于精确定位要删除的行。
+
+例如，我们可以使用窗口函数为每个分组编号，并删除第一个以外的重复行。
+
+```sql
+DELETE FROM table_name 
+WHERE id IN (
+    SELECT id FROM (
+        SELECT 
+            id,  -- 唯一标识符
+            ROW_NUMBER() OVER (
+                PARTITION BY column_field      -- 按此字段判断重复
+                ORDER BY identifier_field      -- 决定保留哪一条
+            ) AS rn
+        FROM table_name
+    ) WHERE rn > 1
+);
+```
+
+或者使用MERGE INTO方式，支持更复杂的匹配逻辑
+
+```sql
+MERGE INTO table_name t
+USING (
+    SELECT id FROM (
+        SELECT id, ROW_NUMBER() OVER (PARTITION BY column_field ORDER BY identifier_field) AS rn
+        FROM table_name
+    ) WHERE rn > 1
+) s
+ON t.id = s.id
+WHEN MATCHED THEN DELETE;
+```
+
+**注意**：窗口函数不能直接在 DELETE 的 WHERE 子句中使用，以下写法会报错：
+
+```sql
+-- ❌ 错误写法
+DELETE FROM table_name
+WHERE ROW_NUMBER() OVER (PARTITION BY column_field ORDER BY identifier_field) > 1;
+```
+
+### 2. 数据分区和聚合
+
+窗口函数可以用于执行分区内的聚合操作，如累计求和和移动平均值。
+
+```sql
+SELECT 
+    product_id, 
+    order_date, 
+    SUM(order_amount) OVER (PARTITION BY product_id ORDER BY order_date) cumulative_sales 
+FROM orders;
+```
+
+### 3. 数据排序和排名
+
+通过窗口函数可以对数据进行排序和排名，并将结果用于后续计算。
+
+```sql
+SELECT 
+    customer_id, 
+    purchase_amount, 
+    RANK() OVER (PARTITION BY region ORDER BY purchase_amount DESC) purchase_rank 
+FROM purchases;
+```
+
+### 4. 数据补全与滞后/前瞻列
+
+利用 `LAG()` 和 `LEAD()` 函数，可以获取前/后行数据，用于补全缺损数据。
+
+```sql
+SELECT 
+    customer_id,
+    order_date,
+    order_amount,
+    LAG(order_amount) OVER (PARTITION BY customer_id ORDER BY order_date) previous_order_amount 
+FROM orders;
+```
+
+使用窗口函数进行 ETL 数据转换，可以有效地提高数据处理的灵活性和效率，使得复杂的数据分析和转换操作变得更加快捷和简洁。
+
+## 数据模型
+
+TPC-H 数据代表一个汽车零部件销售商的数据仓库，其中记录了订单、构成订单的项目（lineitem）、供应商、客户、销售的零部件（part）、地区、国家和零部件供应商（partsupp）。
+
+云器Lakehouse内置了共享的TPC-H数据，每个用户可以通过加上数据上下文直接使用，比如：
+
+```sql
+SELECT * FROM 
+clickzetta_sample_data.tpch_100g.customer
+LIMIT 10;
+```
+
+## 通过云器Lakehouse SQL窗口函数进行数据转换
+
+### 窗口函数有四个基本部分
+
+1. **分区**：根据指定列的值定义一组行。如果没有指定分区，则整个表被视为一个分区。
+2. **ORDER BY**：这个可选子句指定如何在分区内部对行进行排序。
+3. **函数**：应用于当前行的函数。函数结果在输出中添加一个额外的列。
+4. **窗口框架**：在分区内部，窗口框架允许你指定函数计算中要考虑的行。
+
+```sql
+SELECT
+  o_custkey,
+  o_orderdate,
+  o_totalprice,
+  SUM(o_totalprice) -- 函数 
+  OVER (
+    PARTITION BY
+      o_custkey -- 分区
+    ORDER BY
+      o_orderdate -- Order By；除非指定为 DESC，否则为升序
+  ) AS running_sum
+FROM
+  clickzetta_sample_data.tpch_100g.orders
+WHERE
+  o_custkey = 4
+ORDER BY
+  o_orderdate
+LIMIT
+  10;
+```
+
+函数 `SUM` 在上述查询中是一个聚合函数。注意 `running_sum` 如何在所有行上累加（即聚合）`o_totalprice`。行本身按其订单日期升序排列。
+
+**参考**：标准聚合函数是 `MIN, MAX, AVG, SUM, & COUNT`，现代数据系统提供了各种强大的聚合函数。请查阅你的数据库文档以了解可用的聚合函数。请 [阅读此文](agg_function.md) 了解 Lakehouse 中可用的聚合函数列表。
+
+## 使用排名函数获取前/后 n 行
+
+如果你正在处理一个需要获取前/后 n 行（根据某个值定义）的问题，那么使用 **行** 函数。
+
+让我们看看如何使用行函数的一个例子：
+
+从 `orders` 表中**获取每天消费最高的前 3 个客户**。`orders` 表的架构如下所示：
+
+```sql
+SELECT
+  *
+FROM
+  (
+    SELECT
+      o_orderdate,
+      o_totalprice,
+      o_custkey,
+      RANK() -- 排名函数 
+      OVER (
+        PARTITION BY
+          o_orderdate -- 按订单日期分区
+        ORDER BY
+          o_totalprice DESC -- 按总价格降序排列分区内的行
+      ) AS rnk
+    FROM
+      clickzetta_sample_data.tpch_100g.orders
+  )
+WHERE
+  rnk <= 3
+ORDER BY
+  o_orderdate
+LIMIT
+  5;
+```
+
+## 标准排名函数
+
+1. \`\`：在窗口框架内从 1 到 n 对行进行排名。对具有相同值（由 "ORDER BY" 子句定义）的行进行相同的排名，并跳过如果值不同则会存在的排名数字。
+2. \`\`：在窗口框架内从 1 到 n 对行进行排名。对具有相同值（由 "ORDER BY" 子句定义）的行进行相同的排名，并不跳过任何排名数字。
+3. \`\`：在窗口框架内从 1 到 n 添加行号，并不创建任何重复值。
+
+```sql
+-- 让我们看看一个显示 RANK、DENSE_RANK 和 ROW_NUMBER 之间区别的例子
+SELECT 
+    order_date,
+    order_id,
+    total_price,
+    ROW_NUMBER() OVER (PARTITION BY order_date ORDER BY total_price) AS row_number,
+    RANK() OVER (PARTITION BY order_date ORDER BY total_price) AS rank,
+    DENSE_RANK() OVER (PARTITION BY order_date ORDER BY total_price) AS dense_rank
+FROM (
+    SELECT 
+        '2024-07-08' AS order_date, 'order_1' AS order_id, 100 AS total_price UNION ALL
+    SELECT 
+        '2024-07-08', 'order_2', 200 UNION ALL
+    SELECT 
+        '2024-07-08', 'order_3', 150 UNION ALL
+    SELECT 
+        '2024-07-08', 'order_4', 90 UNION ALL
+    SELECT 
+        '2024-07-08', 'order_5', 100 UNION ALL
+    SELECT 
+        '2024-07-08', 'order_6', 90 UNION ALL
+    SELECT 
+        '2024-07-08', 'order_7', 100 UNION ALL
+    SELECT 
+        '2024-07-10', 'order_8', 100 UNION ALL
+    SELECT 
+        '2024-07-10', 'order_9', 100 UNION ALL
+    SELECT 
+        '2024-07-10', 'order_10', 100 UNION ALL
+    SELECT 
+        '2024-07-11', 'order_11', 100
+) AS orders
+ORDER BY order_date, row_number;
+```

+:-: ![](.topwrite/assets/image_1736841886300.png =818)
+
+现在我们已经看到了如何**使用窗口函数**以及如何使用**排名和聚合**函数。
+
+## 为什么在有分区的情况下定义窗口框架？
+
+虽然我们的函数在分区中的行上操作，但窗口框架提供了更精细的方式来操作分区中的一组选定行。
+
+当我们需要在一个分区中操作一组行（例如，滑动窗口）时，我们可以使用窗口框架来定义这些行。
+
+考虑一个场景，你有销售数据，你想计算每个商店的 3 天移动平均销售额：
+
+```sql
+SELECT
+    store_id,
+    sale_date,
+    sales_amount,
+    AVG(sales_amount) OVER (
+        PARTITION BY store_id
+        ORDER BY sale_date
+        ROWS BETWEEN 2 PRECEDING AND CURRENT ROW
+    ) AS moving_avg_sales
+FROM
+    sales;
+```
+
+在这个示例中：
+
+1. **PARTITION BY** store\_id 确保为每个商店分别进行计算。
+2. **ORDER BY** sale\_date 定义每个分区内部行的顺序。
+3. **ROWS BETWEEN 2 PRECEDING AND CURRENT ROW** 指定窗口框架，考虑当前行和前两行来计算移动平均值。
+
+如果没有定义窗口框架，函数可能无法提供你需要的具体移动平均值计算。
+
+## 使用 ROWS 定义窗口框架
+
+**ROWS**：用于根据位置选择与当前行相关的行集。
+
+1. 行定义格式 `ROWS BETWEEN start_point AND end_point`。
+
+   2. start\_point 和 end\_point 可以是以下三个中的任意一个（按正确顺序）：
+
+      1. **n PRECEDING**：当前行前 n 行。UNBOUNDED PRECEDING 表示当前行之前的所有行。
+      2. **n FOLLOWING**：当前行后 n 行。UNBOUNDED FOLLOWING 表示当前行之后的所有行。
+
+让我们看看如何使用相对行号来定义窗口范围。
+
+考虑这个窗口函数：
+
+```sql
+AVG(total_price) OVER ( -- 函数：运行平均值
+    PARTITION BY o_custkey -- 按客户分区
+    ORDER BY order_month 
+    ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING -- 窗口框架定义为 1 行前到 1 行后
+    )
+```
+
+编写一个SQL查询，从 orders 表中获取以下输出：
+
+1. 1. o\_custkey
+   2. order\_month：格式为 YYYY-MM，使用 strftime(o\_orderdate, '%Y-%m') AS order\_month
+   3. total\_price：该月的 o\_totalprice 总和
+   4. three\_mo\_total\_price\_avg：该客户过去、当前和下一个月的 total\_price 平均值
+
+```sql
+SELECT
+  order_month,
+  o_custkey,
+  total_price,
+  ROUND(
+    AVG(total_price) OVER ( -- 函数：运行平均值
+      PARTITION BY
+        o_custkey -- 按客户分区
+      ORDER BY
+        order_month ROWS BETWEEN 1 PRECEDING
+        AND 1 FOLLOWING -- 窗口框架定义为 1 行前到 1 行后
+    ),
+    2
+  ) AS three_mo_total_price_avg
+FROM
+  (
+    SELECT
+      date_format (o_orderdate, 'yyyy-MM') AS order_month,
+      o_custkey,
+      SUM(o_totalprice) AS total_price
+    FROM
+      clickzetta_sample_data.tpch_100g.orders
+    GROUP BY
+      1,
+      2
+  )
+LIMIT
+  5;
+```
+
+## 使用 RANGE 定义窗口框架
+
+1. **RANGE**：用于根据 `ORDER BY` 子句中指定的列的值选择与当前行相关的行集。
+
+   1. 范围定义格式 `RANGE BETWEEN start_point AND end_point`。
+
+   2. start\_point 和 end\_point 可以是以下任意一个：
+
+      1. **CURRENT ROW**：当前行。
+      2. **n PRECEDING**：所有值在指定范围内且小于或等于当前行值的 n 个单位之前的行。
+      3. **n FOLLOWING**：所有值在指定范围内且大于或等于当前行值的 n 个单位之后的行。
+      4. **UNBOUNDED PRECEDING**：分区中当前行之前的所有行。
+      5. **UNBOUNDED FOLLOWING**：分区中当前行之后的所有行。
+
+   3. `RANGE` 在处理数值或日期/时间范围时特别有用，允许进行如运行总计、移动平均值或累积分布等计算。
+
+让我们看看 `RANGE` 如何与 `AVG(total price) OVER (PARTITION BY customer id ORDER BY date RANGE BETWEEN INTERVAL '1' DAY PRECEDING AND '1' DAY FOLLOWING)` 一起工作。
+
+现在我们已经看到了如何使用 ROWS 创建窗口框架，让我们探索如何使用 RANGE 来做这件事。
+
+1. 编写一个查询，从 orders 表中获取以下输出：
+
+   1. order\_month，
+   2. o\_custkey，
+   3. total\_price，
+   4. three\_mo\_total\_price\_avg
+   5. **consecutive\_three\_mo\_total\_price\_avg**：该客户的连续 3 个月 total\_price 平均值。注意，这应该只包括按时间顺序排列的月份。
+
+```sql
+SELECT
+  order_month,
+  o_custkey,
+  total_price,
+  ROUND(
+    AVG(total_price) OVER (
+      PARTITION BY
+        o_custkey
+      ORDER BY
+        CAST(order_month AS DATE) RANGE BETWEEN INTERVAL '1' MONTH PRECEDING
+        AND INTERVAL '1' MONTH FOLLOWING
+    ),
+    2
+  ) AS consecutive_three_mo_total_price_avg,
+  ROUND(
+    AVG(total_price) OVER (
+      PARTITION BY
+        o_custkey
+      ORDER BY
+        order_month ROWS BETWEEN 1 PRECEDING
+        AND 1 FOLLOWING
+    ),
+    2
+  ) AS three_mo_total_price_avg
+FROM
+  (
+    SELECT
+      date_format (o_orderdate, 'yyyy-mm-01') AS order_month,
+      o_custkey,
+      SUM(o_totalprice) AS total_price
+    FROM
+      clickzetta_sample_data.tpch_100g.orders
+    GROUP BY
+      1,
+      2
+  )
+ORDER BY
+  o_custkey,
+  order_month
+LIMIT
+  50;
+```

+
+## 回顾
+
+1. 使用窗口函数时：
+
+   * 计算运行指标（类似于 `GROUP BY`，但保留所有行）
+   * 根据特定列对行进行排名
+   * 从当前行访问其他行的值
+
+2. 窗口有四个关键部分：分区、Order By、函数、窗口框架
+
+3. 使用 ROWS 或 RANGE 定义窗口框架
+
+4. 窗口函数成本较高；注意性能

+### 函数名称：approx_count_distinct
+
+```
+approx_count_distinct(expr)
+```
+
+#### 功能描述
+`approx_count_distinct` 函数采用 `hyperloglog` 算法来近似计算指定列中不同值的数量。当数据集较大时，该函数能够在保证较高性能的同时，得到一个近似的基数估计。需要注意的是，该函数在计算过程中会存在一定的误差。
+
+#### 参数说明
+* `expr`: 需要计算基数的列名，可以是数值类型、浮点类型、字符串类型、时间类型、布尔类型、`DECIMAL`、`BINARY` 等基本数据类型。`expr` 可以是单个列名，也可以是表达式或函数的组合。
+
+#### 返回结果
+* 返回值类型为 `BIGINT` 类型，表示近似计算出的基数。
+* 如果 `expr` 中包含 `NULL` 值，这些值将不会被计算在内。
+
+#### 使用示例
+
+**示例 1：**
+```sql
+SELECT approx_count_distinct(col) FROM VALUES (1), (1), (2), (2), (3), (NULL) AS tab(col);
++-----------------------------+
+| approx_count_distinct(col)  |
++-----------------------------+
+| 3                           |
++-----------------------------+
+```
+
+**示例 2：**
+假设我们有一个名为 `sales` 的表，其中包含以下列：`product_id`（产品ID）、`sale_date`（销售日期）和 `quantity`（数量）。我们想要计算在过去一个月内销售的不同产品的数量，可以使用以下查询：
+```sql
+SELECT approx_count_distinct(product_id)
+FROM sales
+WHERE sale_date >= NOW() - INTERVAL '1 MONTH';
+```
+这将返回过去一个月内销售的不同产品数量的近似值。
+
+**示例 3：**
+如果我们想要计算某个特定类别下销售的不同产品数量，可以结合使用 `approx_count_distinct` 函数和其他条件，如下所示：
+```sql
+SELECT approx_count_distinct(product_id)
+FROM sales
+WHERE category = 'Electronics' AND sale_date >= NOW() - INTERVAL '1 MONTH';
+```
+这将返回过去一个月内在电子产品类别下销售的不同产品数量的近似值。

+### 函数名称：approx_top_k
+
+```sql
+approx_top_k(col, k, [maxItemsTracked])
+```
+
+#### 功能描述
+
+该函数用于从指定列（`col`）中提取出现频率最高的前 `k` 个项目值，并返回它们的近似计数。这是一个基于概率的数据结构实现，因此结果可能会有一定的误差，但在大多数情况下，它能有效地反映数据的分布情况。
+
+#### 参数说明
+
+* `col`: 输入列，可以是数值类型、字符串类型或嵌套类型。
+* `k`: 需要返回的前 `k` 个最常出现项的数目，需为大于 0 的整数值。
+* `maxItemsTracked`: 可选参数，用于指定跟踪的最大项目数。默认值为 10000。如果指定的 `maxItemsTracked` 大于或等于 `k`，则使用指定值；否则，将使用 `k` 作为跟踪的最大项目数。
+
+#### 返回结果
+
+函数返回一个结构化数组，每个元素为一个结构体，包含三个字段：`item`（原始输入类型的值）、`count`（长整型，表示该项出现的近似次数）和 `approximation`（布尔值，表示结果是否为近似值，始终为 `true`）。数组按照 `count` 字段降序排列。
+
+#### 使用示例
+
+以下示例展示了如何使用 `approx_top_k` 函数来获取数据中最常见的项目及其出现次数。
+
+**示例 1**：
+
+```sql
+SELECT approx_top_k(col, 1) FROM VALUES (7), (7), (6), (9), (8), (7) AS tab(col);
++-------------------------+
+|  approx_top_k(col, 1)   |
++-------------------------+
+| [{"value":7,"count":3}] |
++-------------------------+
+```
+
+**示例 2**：
+
+```sql
+SELECT approx_top_k(col, 2, 100) FROM VALUES (7), (6), (6), (7), (9), (8), (7) AS tab(col);
++-----------------------------------------------+
+|           approx_top_k(col, 2, 100)           |
++-----------------------------------------------+
+| [{"value":7,"count":3},{"value":6,"count":2}] |
++-----------------------------------------------+
+```
+
+**示例 3**：
+
+```sql
+SELECT approx_top_k(col, 3)
+FROM VALUES ('apple'), ('banana'), ('apple'), ('orange'), ('banana'), ('apple') AS tab(col);
++-----------------------------------------------------------------------------------------+
+|                                  approx_top_k(col, 3)                                   |
++-----------------------------------------------------------------------------------------+
+| [{"value":"apple","count":3},{"value":"banana","count":2},{"value":"orange","count":1}] |
++-----------------------------------------------------------------------------------------+
+```
+
+**注意**：
+
+* 由于 `approx_top_k` 函数是基于概率的，因此返回的结果可能会有一定的误差。在实际应用中，可以通过调整 `maxItemsTracked` 参数来平衡精度和性能。
+* 当处理大量数据时，为了提高性能，可以适当降低 `maxItemsTracked` 的值。但请注意，这可能会影响结果的准确性。

+```
+
+#### 功能描述
+
+`collect_set` 函数用于从输入的一组数据中收集并返回一个不重复的元素集合。该函数可以确保返回的数组中不包含重复的元素，从而使结果更加简洁明了。当指定 `DISTINCT` 关键字时，函数会对结果进行去重处理，但请注意，即使不指定 `DISTINCT`，`collect_set` 函数也会进行去重操作，因此 `DISTINCT` 关键字在此场景下不影响结果。
+
+#### 参数说明
+
+* `expr`：可以是任意数据类型的表达式。
+* `limit`：可选参数，整数类型，表示最多收集的元素个数。如果不指定，则收集所有元素。
+
+#### 返回结果
+
+* 返回一个数组（`ARRAY`），数组中的元素类型与输入参数类型相同。
+* 即使使用 `DISTINCT` 关键字，也不会影响去重结果。
+* 如果指定了 `limit` 参数，则返回的数组最多包含 `limit` 个元素。
+* 返回的数组元素顺序不保证与输入顺序相同。
+* 输入的 `NULL` 值不会包含在结果数组中。
+
+#### 使用示例
+
+**示例 1：基本使用**
+
+```sql
+SELECT collect_set(col) FROM VALUES (1), (2), (1), (NULL) AS tab(col);
++------------------+
+| collect_set(col) |
++------------------+
+| [2,1]            |
++------------------+
+```
+
+**示例 2：去重操作**
+
+```sql
+SELECT collect_set(DISTINCT col)
+FROM VALUES ("a"), ("b"), (NULL), ("c"), ("a") AS tab(col);
++---------------------------+
+| collect_set(DISTINCT col) |
++---------------------------+
+| ["c","b","a"]             |
++---------------------------+
+```
+
+**示例 3：使用 FILTER 子句条件性地收集集合**
+
+```sql
+SELECT collect_set(col) FILTER (WHERE col > 1) FROM VALUES (1), (2), (3), (2), (4) AS tab(col);
++-------------------------------------------+
+| collect_set(col) FILTER (WHERE (col > 1)) |
++-------------------------------------------+
+| [4,3,2]                                   |
++-------------------------------------------+
+```
+
+**示例 4：结合 FILTER 子句和 DISTINCT 收集条件集合**
+
+```sql
+SELECT collect_set(DISTINCT col) FILTER (WHERE col != 'a') FROM VALUES ('a'), ('b'), ('c'), ('b') AS tab(col);
++----------------------------------------------------------+
+| collect_set(DISTINCT col) FILTER (WHERE (NOT (col = 'a')))|
++----------------------------------------------------------+
+| ["c","b"]                                                |
++----------------------------------------------------------+
+```
+
+**示例 5：使用 limit 参数限制返回的元素个数**
+
+```sql
+SELECT collect_set(col, 2) FROM VALUES (1), (2), (3), (4), (2) AS tab(col);
++---------------------+
+| collect_set(col, 2) |
++---------------------+
+| [2,1]               |
++---------------------+
+```
+
+#### 注意事项
+
+* 当处理大量数据时，请注意 `collect_set` 函数可能会消耗较多的内存资源。
+* 由于返回的数组元素顺序不保证与输入顺序相同，若需要排序，请使用其他函数（如 `ARRAY_SORT`）对结果进行排序处理。

+### 收集集合并转换为数组函数：COLLECT_SET_ON_ARRAY
+
+```
+collect_set_on_array([DISTINCT] expr [, limit])
+```
+
+#### 功能描述
+
+`collect_set_on_array` 函数用于从输入的数组表达式中提取不重复的元素，并将这些元素组成一个新的数组。当指定 `DISTINCT` 关键字时，函数会对结果进行去重处理。但请注意，即使不指定 `DISTINCT`，该函数本身就具有去重的功能，因此 `DISTINCT` 关键字在此场景下并不会产生额外的效果。
+
+#### 参数说明
+
+* `expr`：输入的数组类型表达式。
+* `limit`：可选参数，整数类型，表示最多收集的元素个数。如果不指定，则收集所有元素。
+
+#### 返回结果
+
+返回一个数组，数组中的元素类型与输入数组的元素类型相同。如果指定了 `limit` 参数，则返回的数组最多包含 `limit` 个元素。结果数组中的元素顺序不保证与输入数组相同，且数组中的 `NULL` 值不会参与计算。
+
+#### 使用示例
+
+以下示例展示了如何使用 `collect_set_on_array` 函数处理不同的输入数组，并返回去重后的结果数组。
+
+示例 1：
+
+```sql
+SELECT array_sort(collect_set_on_array(a)) AS result
+FROM VALUES
+  (ARRAY(3, 3, 4)),
+  (NULL),
+  (ARRAY(2, 2, 3)),
+  (ARRAY(NULL)),
+  (ARRAY(1, NULL, 2)),
+  (ARRAY(1, 2, 2))
+AS t(a);
++-----------+
+|  result   |
++-----------+
+| [1,2,3,4] |
++-----------+
+```
+
+示例 2：
+
+```sql
+SELECT array_sort(collect_set_on_array(DISTINCT a)) AS result
+FROM VALUES
+  (ARRAY(1, 1, 2)),
+  (ARRAY(2, 3, 3)),
+  (ARRAY(4, 5, 5))
+AS t(a);
++-------------+
+|   result    |
++-------------+
+| [1,2,3,4,5] |
++-------------+
+```
+
+示例 3：使用 limit 参数限制返回的元素个数
+
+```sql
+SELECT array_sort(collect_set_on_array(a, 3)) AS result
+FROM VALUES
+  (ARRAY(3, 3, 4)),
+  (NULL),
+  (ARRAY(2, 2, 3)),
+  (ARRAY(NULL)),
+  (ARRAY(1, NULL, 2)),
+  (ARRAY(1, 2, 2))
+AS t(a);
++---------+
+| result  |
++---------+
+| [2,3,4] |
++---------+
+```
+
+#### 注意事项
+
+* 当输入数组全为 `NULL` 时，`collect_set_on_array` 函数将返回一个空数组。

+### CORR 函数
+
+```
+corr(y, x)
+```
+
+#### 功能描述
+
+`CORR` 函数用于计算两个数值列之间的皮尔逊相关系数（Pearson correlation coefficient）。相关系数衡量两个变量之间的线性相关程度，取值范围为 -1 到 1。
+
+#### 参数说明
+
+* `y`：数值类型的表达式，作为因变量。必须是可以转换为 `DOUBLE` 的数值类型。
+* `x`：数值类型的表达式，作为自变量。必须是可以转换为 `DOUBLE` 的数值类型。
+
+#### 返回类型
+
+* 返回 `DOUBLE` 类型的皮尔逊相关系数，取值范围为 [-1, 1]。
+  * `1`：完全正相关（x 增大，y 也增大）
+  * `-1`：完全负相关（x 增大，y 减小）
+  * `0`：无线性相关
+  * 接近 `1` 或 `-1`：强相关
+  * 接近 `0`：弱相关或无相关
+
+#### 注意事项
+
+* 函数计算过程中，`NULL` 值将被忽略，不参与计算。
+* 如果所有 x 值相同或所有 y 值相同（标准差为 0），返回 `NULL`。
+* 如果有效数据点少于 2 个，返回 `NULL`。
+* 计算公式：`corr(y, x) = covar_pop(y, x) / (stddev_pop(y) * stddev_pop(x))`，即协方差除以两个变量标准差的乘积。
+
+#### 使用示例
+
+1. 基本用法：计算相关系数
+
+```sql
+SELECT corr(c1, c2)
+FROM VALUES (3, 2), (3, 3), (3, 3), (6, 4) AS tab(c1, c2);
++--------------------+
+| corr(c1, c2)       |
++--------------------+
+| 0.816496580927726  |
++--------------------+
+```
+
+2. 完全正相关（y = x）
+
+```sql
+SELECT corr(x, y)
+FROM VALUES (1, 1), (2, 2), (3, 3), (4, 4) AS t(x, y);
++-------------+
+| corr(x, y)  |
++-------------+
+| 1.0         |
++-------------+
+```
+
+3. 完全负相关（y = -x）
+
+```sql
+SELECT corr(x, y)
+FROM VALUES (1, -1), (2, -2), (3, -3), (4, -4) AS t(x, y);
++-------------+
+| corr(x, y)  |
++-------------+
+| -1.0        |
++-------------+
+```
+
+4. 无相关（x 和 y 独立）
+
+```sql
+SELECT corr(x, y)
+FROM VALUES (1, 1), (2, 1), (3, 1), (4, 1) AS t(x, y);
++-------------+
+| corr(x, y)  |
++-------------+
+| NULL        |
++-------------+
+```
+
+5. 按分组计算相关系数
+
+```sql
+SELECT
+  category,
+  corr(price, quantity) as price_quantity_corr
+FROM VALUES
+  ('A', 10, 100),
+  ('A', 20, 80),
+  ('A', 30, 60),
+  ('B', 15, 50),
+  ('B', 25, 40),
+  ('B', 35, 30)
+AS sales(category, price, quantity)
+GROUP BY category;
++----------+----------------------+

+### COUNT 函数
+
+#### 简介
+
+`COUNT` 函数用于返回一组数据的行数。它可以统计所有行的数量，也可以统计指定列中非 `NULL` 值的数量，或者统计指定列中不同值的数量。
+
+#### 语法
+
+```sql
+COUNT(*) [FILTER (WHERE condition)]
+COUNT([DISTINCT] expr1[, expr2, ...]) [FILTER (WHERE condition)]
+```
+
+#### 参数
+
+* `exprN`: 任意类型的表达式。
+
+#### 返回结果
+
+* 返回值类型为 `BIGINT` 类型。
+* 使用 `COUNT(*)` 形式时，所有行都会计入总数，包括包含 `NULL` 值的行。
+* 使用 `COUNT(expr1[, expr2, ...])` 形式时，如果某一行的任意列为 `NULL`，该行将被忽略。
+* 使用 `COUNT(DISTINCT expr1[, expr2, ...])` 形式时，首先对指定列进行去重，然后统计非 `NULL` 值的数量。
+
+#### 示例
+
+1. 统计所有行的数量（包括包含 `NULL` 值的行）：
+```sql
+SELECT COUNT(*) FROM VALUES (NULL), (1), (3), (4) AS tab(col);
++----------+
+| count(1) |
++----------+
+| 4        |
++----------+
+```
+
+2. 统计指定列中非 `NULL` 值的数量：
+```sql
+SELECT COUNT(a, b) FROM VALUES (NULL, NULL), (1, NULL), (NULL, 3), (4, 5) AS tab(a, b);
++------------+
+| count(a,b) |
++------------+
+| 1          |
++------------+
+```
+
+3. 统计指定列中不同值的数量（忽略 `NULL` 值）：
+```sql
+SELECT COUNT(DISTINCT a, b)
+FROM VALUES (1, NULL), (1, NULL), (4, 5), (4, 5), (1, 2) AS tab(a, b);
++-----------------------+
+| count(DISTINCT a, b)  |
++-----------------------+
+| 2                     |
++-----------------------+
+```
+
+4. 统计某一列中特定值的数量：
+```sql
+SELECT COUNT(*) FROM customers WHERE status = 'active';
++----------+
+| count(1) |
++----------+
+| 150      |
++----------+
+```
+
+5. 统计销售记录中不同产品的销售数量（忽略 `NULL` 值）：
+```sql
+SELECT COUNT(DISTINCT product_id) FROM sales_records;
++------------------------------+
+| count(DISTINCT `product_id`) |
++------------------------------+
+| 50                           |
++------------------------------+
+```
+
+6. 使用 FILTER 子句条件性地统计行数：
+```sql
+SELECT COUNT(*) FILTER (WHERE col > 2) FROM VALUES (1), (2), (3), (4), (NULL) AS tab(col);
++--------------------------------------+
+| count(1) FILTER (WHERE (col > 2))    |
++--------------------------------------+
+| 2                                    |
++--------------------------------------+
+```
+
+7. 结合 FILTER 子句和 DISTINCT 统计不同值的数量：
+```sql
+SELECT COUNT(DISTINCT a) FILTER (WHERE b > 1) FROM VALUES (1, 1), (1, 2), (2, 2), (3, 1) AS tab(a, b);
++------------------------------------------------------+
+| count(DISTINCT a) FILTER (WHERE (b > 1))             |
++------------------------------------------------------+
+| 2                                                    |
++------------------------------------------------------+
+```

+### COUNT_DISTINCT 函数
+
+```
+count_distinct(expr)
+```
+
+#### 功能描述
+
+`COUNT_DISTINCT` 函数用于计算指定列中不同值（去重后）的数量。这是一个聚合函数，等价于 `COUNT(DISTINCT expr)`，但在某些场景下优化器可能会做特殊优化。
+
+#### 参数说明
+
+* `expr`：任意类型的表达式，要计算其不同值的数量。
+
+#### 返回类型
+
+* 返回 `BIGINT` 类型（非空）。
+* 返回不同值的数量。
+
+#### 注意事项
+
+* 函数计算过程中，`NULL` 值会被忽略，不计入结果。
+* 如果所有值都是 `NULL`，返回 0。
+* 如果输入为空集，返回 0。
+* `COUNT_DISTINCT` 需要维护所有不同值的集合，内存开销较大。对于大数据集，如果只需要近似值，考虑使用 `APPROX_COUNT_DISTINCT`。
+
+#### 使用示例
+
+1. 基本用法：计算不同值的数量
+
+```sql
+SELECT count_distinct(city)
+FROM VALUES ('Beijing'), ('Shanghai'), ('Beijing'), ('Shenzhen') AS t(city);
++------------------------+
+| count_distinct(city)   |
++------------------------+
+| 3                      |
++------------------------+
+```
+
+2. 等价于 COUNT(DISTINCT ...)
+
+```sql
+SELECT count_distinct(city), COUNT(DISTINCT city)
+FROM VALUES ('Beijing'), ('Shanghai'), ('Beijing'), ('Shenzhen') AS t(city);
++------------------------+----------------------+
+| count_distinct(city)   | COUNT(DISTINCT city) |
++------------------------+----------------------+
+| 3                      | 3                    |
++------------------------+----------------------+
+```
+
+3. NULL 值被忽略
+
+```sql
+SELECT count_distinct(value)
+FROM VALUES (1), (2), (NULL), (1), (NULL), (3) AS t(value);
++-------------------------+
+| count_distinct(value)   |
++-------------------------+
+| 3                       |
++-------------------------+
+```
+
+4. 所有值都是 NULL 时返回 0
+
+```sql
+SELECT count_distinct(value)
+FROM VALUES (NULL), (NULL), (NULL) AS t(value);
++-------------------------+
+| count_distinct(value)   |
++-------------------------+
+| 0                       |
++-------------------------+
+```
+
+5. 按分组计算不同值数量
+
+```sql
+SELECT dept, count_distinct(name) as unique_employees
+FROM VALUES
+  ('Sales', 'Alice'),
+  ('Sales', 'Bob'),
+  ('Sales', 'Alice'),
+  ('IT', 'Charlie'),
+  ('IT', 'David'),
+  ('IT', 'Charlie')
+AS employees(dept, name)
+GROUP BY dept;
++-------+------------------+
+| dept  | unique_employees |
++-------+------------------+
+| Sales | 2                |
+| IT    | 2                |

+### COUNT_IF 函数
+
+#### 功能描述
+
+`COUNT_IF` 函数用于计算表达式中值为 `TRUE` 的行数。该函数可以处理任意返回布尔值的表达式，并返回一个 `BIGINT` 类型的数值结果。需要注意的是，`NULL` 值不会影响计数结果。
+
+#### 语法格式
+
+```sql
+COUNT_IF([DISTINCT] expr1)
+```
+
+#### 参数说明
+
+* `expr1`: 需要计算的布尔表达式。返回值为 `TRUE` 或 `FALSE` 的任意表达式。
+
+#### 返回结果
+
+* 返回值为 `BIGINT` 类型，表示表达式为 `TRUE` 的行数。
+* 如果使用 `DISTINCT` 关键字，则只计算不同的 `TRUE` 值，重复的 `TRUE` 值只计算一次。
+
+#### 使用示例
+
+**示例 1**：计算不同的 `TRUE` 值数量
+
+```sql
+SELECT count_if(col % 2 = 0) FROM VALUES (NULL), (0), (1), (2), (2), (3) AS tab(col);
++-----------------------+
+| count_if(col % 2 = 0) |
++-----------------------+
+| 3                     |
++-----------------------+
+```
+
+**示例 2**：结合 `DISTINCT` 使用
+
+```sql
+SELECT count_if(DISTINCT col % 2 = 0)
+FROM VALUES (NULL), (0), (1), (2), (2), (3) AS tab(col);
++--------------------------------+
+| count_if(DISTINCT col % 2 = 0) |
++--------------------------------+
+| 1                              |
++--------------------------------+
+```
+
+**示例 3**：计算 `NULL` 值的数量
+
+```sql
+SELECT count_if(col IS NULL) FROM VALUES (NULL), (0), (1), (2), (3) AS tab(col);
++-------------------------+
+| count_if((col) IS NULL) |
++-------------------------+
+| 1                       |
++-------------------------+
+```
+
+#### 注意事项
+
+* `COUNT_IF` 函数仅适用于返回布尔值的表达式。
+* 使用 `DISTINCT` 关键字时，确保表达式返回的值可以用于区分重复的 `TRUE` 值。
+* `NULL` 值不会影响计数结果。

+### FIRST_VALUE 函数
+
+```
+first_value(expr [, ignoreNulls]) [FILTER (WHERE condition)]
+first(expr [, ignoreNulls]) [FILTER (WHERE condition)]
+```
+
+#### 功能描述
+
+`FIRST_VALUE` 函数用于返回聚合组或窗口中的第一个值。可以选择是否忽略 `NULL` 值。`first` 是 `first_value` 的别名。
+
+#### 参数说明
+
+* `expr`：任意类型的表达式，要获取其第一个值。
+* `ignoreNulls`：可选的布尔值参数，默认为 `false`。
+  * `false`（默认）：返回第一个值，即使是 `NULL`
+  * `true`：忽略 `NULL` 值，返回第一个非 `NULL` 值
+
+#### 返回类型
+
+* 返回与输入表达式相同的数据类型。
+* 返回聚合组或窗口中的第一个值。
+
+#### 注意事项
+
+* 如果所有值都是 `NULL`（且 `ignoreNulls` 为 `true`），返回 `NULL`。
+* 如果输入为空集，返回 `NULL`。
+* 值的顺序取决于数据的输入顺序（不确定）。使用 `WITHIN GROUP (ORDER BY ...)` 可以指定确定性的顺序。
+
+#### 使用示例
+
+1. 基本用法：返回第一个值
+
+```sql
+SELECT first_value(col), first(col)
+FROM VALUES (10), (5), (20) AS tab(col);
++------------------+------------+
+| first_value(col) | first(col) |
++------------------+------------+
+| 10               | 10         |
++------------------+------------+
+```
+
+2. 处理 NULL 值（默认返回第一个值，即使是 NULL）
+
+```sql
+SELECT first_value(col), first(col)
+FROM VALUES (NULL), (5), (NULL) AS tab(col);
++------------------+------------+
+| first_value(col) | first(col) |
++------------------+------------+
+| NULL             | NULL       |
++------------------+------------+
+```
+
+3. 忽略 NULL 值，返回第一个非 NULL 值
+
+```sql
+SELECT first_value(col, true), first(col, true)
+FROM VALUES (NULL), (5), (NULL) AS tab(col);
++------------------------+-------------------+
+| first_value(col, true) | first(col, true)  |
++------------------------+-------------------+
+| 5                      | 5                 |
++------------------------+-------------------+
+```
+
+4. 使用 WITHIN GROUP (ORDER BY ...) 指定顺序
+
+```sql
+SELECT a,
+       first_value(b) WITHIN GROUP(ORDER BY c) as first_b,
+       first_value(b, true) WITHIN GROUP(ORDER BY c) as first_non_null_b
+FROM VALUES
+  ('apple', 11, 22),
+  ('apple', 1, 2),
+  ('orange', NULL, 1),
+  ('orange', 111, 2),
+  ('orange', NULL, 3)
+AS t(a, b, c)
+GROUP BY a;
++--------+---------+------------------+
+| a      | first_b | first_non_null_b |
++--------+---------+------------------+
+| apple  | 1       | 1                |
+| orange | NULL    | 111              |
++--------+---------+------------------+
+```
+
+5. 获取每个分组的第一个和最后一个值
+
+```sql
+SELECT
+  category,
+  first_value(value) as first_val,
+  last_value(value) as last_val
+FROM VALUES
+  ('A', 10),
+  ('A', 20),
+  ('B', 30),
+  ('B', 40)
+AS t(category, value)
+GROUP BY category;
++----------+-----------+----------+
+| category | first_val | last_val |
++----------+-----------+----------+
+| A        | 10        | 20       |
+| B        | 30        | 40       |
++----------+-----------+----------+
+```
+
+6. 使用 FILTER 子句条件性地获取第一个值
+
+```sql
+SELECT first_value(col) FILTER (WHERE col > 5)
+FROM VALUES (3), (10), (7), (12) AS tab(col);
++-------------------------------------------+
+| first_value(col) FILTER (WHERE (col > 5)) |
++-------------------------------------------+
+| 10                                        |
++-------------------------------------------+
+```

+# GROUP_BITMAP 函数
+
+## 简介
+
+`GROUP_BITMAP` 函数是一个聚合函数，用于对一组无符号整数值进行聚合，计算出对应的 Bitmap（位图）数据结构。该函数在处理大规模数据集时非常高效，尤其适用于需要对大量整数值进行集合操作（如并集、交集等）的场景。
+
+## 语法
+
+```sql
+group_bitmap(value)
+```
+
+## 参数
+
+* `value`：`INTEGER` 或 `BIGINT` 类型的表达式，表示需要聚合的整数值。通常，这些值是从数据表的某一列中提取的。
+
+## 返回值
+
+返回一个 `INT` 类型的结果，表示聚合后的位图。`Bitmap` 是一种紧凑的数据结构，通过位表示法存储整数值的存在性。每个位对应一个整数值，如果该位为 1，则表示对应的整数值存在于集合中；如果该位为 0，则表示对应的整数值不存在于集合中。
+
+## 使用示例
+
+示例 1：基本用法
+
+```sql
+SELECT group_bitmap(v) AS bitmap_result
+FROM VALUES (1), (2), (3), (4), (5) AS t(v);
++---------------+
+| bitmap_result |
++---------------+
+| 5             |
++---------------+
+```
+
+**结果**：
+返回一个 `INT` 类型的位图。
+
+## 注意事项
+
+1. **输入值范围**：`group_bitmap` 函数适用于无符号整数值。如果输入值为负数，可能会导致意外的结果或错误。
+2. **性能优化**：在处理大规模数据集时，`group_bitmap` 函数非常高效。但如果数据量过大，仍需注意性能影响。在可能的情况下，可尝试优化输入数据以提高函数执行效率。
+3. **中间状态的使用**：如果需要对多个分组进行聚合操作，建议使用 `group_bitmap_state` 和 `group_bitmap_merge` 函数，以避免重复计算。

+### GROUP_BITMAP_MERGE_STATE 函数
+
+#### 功能描述
+`GROUP_BITMAP_MERGE_STATE` 函数用于对多个位图（`bitmap`）值进行合并操作，合并这些值并返回它们的并集。该函数特别适用于处理分类数据，能够高效地合并具有相同分类的位图表示，从而得到一个包含所有类别元素的位图。
+
+#### 参数说明
+- **`bitmap`**：输入参数，类型为位图（`BITMAP`）。指需要进行逻辑“或”操作的位图列的值。
+
+#### 返回结果
+函数返回一个位图类型的值，该值包含了输入参数中所有位图值的并集。
+
+#### 使用示例
+以下示例展示了如何使用 `GROUP_BITMAP_MERGE_STATE` 函数来计算位图的逻辑“或”运算结果，并进一步计算其基数（`cardinality`）：
+
+```sql
+SELECT c, bitmap_cardinality(GROUP_BITMAP_MERGE_STATE(bitmap_build(v))) AS b
+FROM (
+  VALUES ('a', ARRAY(1)), ('a', ARRAY(2)), ('a', ARRAY(2)), ('b', ARRAY(3)), ('b', NULL)
+) AS t(c, v)
+GROUP BY c;
++---+---+
+| c | b |
++---+---+
+| a | 2 |
+| b | 1 |
++---+---+
+```
+
+在这个查询中，我们创建了一个包含分类 `c` 和与之对应的位图值 `v` 的表。然后，我们使用 `GROUP_BITMAP_MERGE_STATE` 函数对每个分类下的位图值进行合并。对于分类 `a`，合并后的位图包含了 `[1, 2]`；对于分类 `b`，合并后的位图包含了 `[3]`。最终，查询结果将显示每个分类的合并位图的基数。

+### GROUP_BITMAP_STATE 函数

+
+#### 参数说明
+- `expr`：待处理的整数类型表达式。
+
+#### 返回类型
+- 返回一个 `BITMAP` 类型的结果。
+
+#### 使用示例
+以下是一个使用 `group_bitmap_state` 函数的示例。我们有一个包含两列的数据表，分别为 `c` 和 `v`。我们希望根据 `c` 列的值进行分组，并将 `v` 列中每个分组的唯一值转换为一个 `bitmap` 数组。
+
+```sql
+SELECT c, bitmap_to_array(group_bitmap_state(v)) AS bitmap_array

++----+--------------+
+| a  | [1,2]        |
+| b  | [3]          |
++----+--------------+
+```
+
+在这个示例中，我们可以看到 `a` 分组包含两个唯一值 1 和 2，因此返回的 `bitmap` 数组为 `[1,2]`。而 `b` 分组只包含一个唯一值 3，所以返回的 `bitmap` 数组为 `[3]`。

+  AS t(v)
+);
++--------------+
+| final_bitmap |
++--------------+
+| 10           |
++--------------+
+```
+
+**结果**：
+返回一个完整的 `Bitmap`，表示所有输入 `Bitmap` 的按位异或操作的结果。
+
+示例 3：直接计算最终结果
+
+`group_bitmap_xor` 函数用于直接计算按位异或操作的最终结果，适用于不需要中间状态的场景。
+
+```sql
+SELECT group_bitmap_xor(bitmap_build(v)) AS final_bitmap
+FROM VALUES
+  (ARRAY(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)),
+  (ARRAY(6, 7, 8, 9, 10, 11, 12, 13, 14, 15)),
+  (ARRAY(2, 4, 6, 8, 10, 12))
+AS t(v);
++--------------+
+| final_bitmap |
++--------------+
+| 10           |
++--------------+
+```
+
+**结果**：
+返回一个完整的 `Bitmap`，表示所有输入 `Bitmap` 的按位异或操作的结果。
+
+## 注意事项
+
+1. **输入类型**：请确保输入的 `bitmap` 是 `BITMAP` 类型，否则会导致函数执行失败。
+2. **中间状态的使用**：返回的中间状态可以用于后续的合并操作，从而实现更复杂的聚合逻辑。
+3. **性能优化**：在处理大规模数据集时，`group_bitmap_xor_state` 函数非常高效。但如果数据量过大，仍需注意性能影响。在可能的情况下，尝试优化输入数据以提高函数执行效率。
+4. **客户端支持**：客户端可能不支持直接打印 `BITMAP` 类型的结果。如果需要查看结果，可以使用 `bitmap_to_array` 函数将 `Bitmap` 转换为数组形式。
+
+## 相关函数
+
+* `group_bitmap_xor`：直接计算按位异或操作的最终结果。
+* `group_bitmap_merge`：合并多个中间状态的 `Bitmap` 对象。
+* `bitmap_xor`：对两个 `Bitmap` 进行按位异或操作。
+* `bitmap_to_array`：将 `Bitmap` 转换为数组形式，便于查看结果。

+#### 简介
+
+`group_concat` 函数用于将一组字符串值连接成一个单一的字符串。当处理多个行或记录时，此函数非常有用，可以将来自同一组的结果合并为一个字符串，通常用于报表生成和数据汇总场景。
+
+#### 语法
+
+```sql
+group_concat(expression [SEPARATOR sep_string]) [FILTER (WHERE condition)]
+```
+
+#### 参数
+
+* `expression`: 要连接的列或表达式。
+* `sep_string`: （可选）用作分隔符的字符串。如果省略，`Lakehouse` 默认使用逗号（`,`）作为分隔符。
+
+#### 返回结果
+
+* 返回一个字符串，其中包含连接后的所有非 `NULL` 值，值之间由指定的分隔符分隔。
+
+#### 使用示例
+
+1. 基本使用：
+
+```sql
+SELECT a, group_concat(b SEPARATOR "-")
+FROM VALUES ('A1', 2), ('A1', 1), ('A2', 3), ('A1', 1) AS tab(a, b)
+GROUP BY a;
++----+-------------------+
+| a  | WM_CONCAT('-', b) |
++----+-------------------+
+| A2 | 3                 |
+| A1 | 2-1-1             |
++----+-------------------+
+```
+
+2. 使用 FILTER 子句条件性地连接字符串：
+
+```sql
+SELECT a, group_concat(b SEPARATOR "-") FILTER (WHERE b > 1)
+FROM VALUES ('A1', 2), ('A1', 1), ('A2', 3), ('A1', 3) AS tab(a, b)
+GROUP BY a;
++----+----------------------------------------------------+
+| a  | WM_CONCAT('-', b) FILTER (WHERE (b > 1))           |
++----+----------------------------------------------------+
+| A2 | 3                                                  |
+| A1 | 2-3                                                |
++----+----------------------------------------------------+
+```
+
+#### 注意事项
+
+* 如果结果字符串超过系统设定的最大长度限制，`group_concat` 可能会报错。在 `Lakehouse` 中，可以通过设置表属性 `cz.storage.write.max.string.bytes` 系统变量来调整这个限制。
+* 在使用 `group_concat` 函数时，应注意 `NULL` 值会被忽略，不会包含在最终的字符串中。

+| 10                  |
++---------------------+
+```
+
+5. 使用 FILTER 子句条件性地找出最小值：
+
+```sql
+SELECT min(col) FILTER (WHERE col > 15) FROM VALUES (10), (20), (50), (NULL) AS tab(col);
++---------------------------------------+
+| `min`(col) FILTER (WHERE (col > 15))  |
++---------------------------------------+
+| 20                                    |
++---------------------------------------+
+```
+
+6. 结合 FILTER 子句和 DISTINCT 找出条件最小值：
+
+```sql
+SELECT min(DISTINCT col) FILTER (WHERE col < 50) FROM VALUES (10), (10), (20), (50) AS tab(col);
++------------------------------------------------------+
+| `min`(DISTINCT col) FILTER (WHERE (col < 50))        |

+### MIN_BY 函数
+
+```sql
+min_by(expr1, expr2) [FILTER (WHERE condition)]
+```
+
+#### 功能描述
+
+`MIN_BY` 函数用于从一组数据中找出与 `expr2` 中最小值相关联的 `expr1` 的值。该函数在处理成对的数据时非常有用，可以帮助您快速找到与特定条件相关的最佳匹配项。
+
+#### 参数说明
+
+* `expr1`：任何数据类型。这是您希望根据 `expr2` 的最小值返回的值。
+* `expr2`：可比较的数据类型，包括数值类型（如 `TINYINT`、`SMALLINT`、`INT`、`BIGINT`、`FLOAT`、`DOUBLE`、`DECIMAL`），时间类型（如 `DATE`、`TIMESTAMP`），字符串类型（如 `CHAR`、`VARCHAR`、`STRING`）以及二进制类型（如 `BINARY`）。
+
+#### 返回结果
+
+* 返回结果的类型与 `expr1` 的类型相匹配。
+* 如果 `expr2` 中的所有值均为 `NULL`，则返回结果也为 `NULL`。
+
+#### 使用示例
+
+1. 数值类型的示例：
+
+```sql
+SELECT min_by(num1, num2)
+FROM VALUES
+  ((1, 10)),
+  ((2, 20)),
+  ((3, 5)),
+  ((4, 30))
+AS tab(num1, num2);
++--------------------+
+| min_by(num1, num2) |
++--------------------+
+| 3                  |
++--------------------+
+```
+
+在这个示例中，我们可以看到 `num2` 的最小值是 5，与它相关联的 `num1` 的值是 3。
+
+2. 时间类型的示例：
+
+```sql
+SELECT min_by(date1, date2)
+FROM VALUES
+  (('2022-01-01', '2023-01-01')),
+  (('2022-02-01', '2022-12-31')),
+  (('2022-03-01', '2022-01-01'))
+AS tab(date1, date2);
++----------------------+
+| min_by(date1, date2) |
++----------------------+
+| 2022-03-01           |
++----------------------+
+```
+
+在这个示例中，我们可以看到 `date2` 的最小值是 '2022-01-01'，与它相关联的 `date1` 的值也是 '2022-01-01'。
+
+3. 字符串类型的示例：
+
+```sql
+SELECT min_by(str1, str2)
+FROM VALUES
+  (('apple', 'A')),
+  (('banana', 'B')),
+  (('cherry', 'C'))
+AS tab(str1, str2);
++--------------------+
+| min_by(str1, str2) |
++--------------------+
+| apple              |
++--------------------+
+```
+
+在这个示例中，我们可以看到 `str2` 的最小值是 'A'，与它相关联的 `str1` 的值是 'apple'。
+
+4. 使用 FILTER 子句条件性地查找关联值：
+
+```sql
+SELECT min_by(num1, num2) FILTER (WHERE num2 > 10)
+FROM VALUES
+  ((1, 10)),
+  ((2, 20)),
+  ((3, 5)),
+  ((4, 30))
+AS tab(num1, num2);
++------------------------------------------------+
+| min_by(num1, num2) FILTER (WHERE (num2 > 10))  |
++------------------------------------------------+
+| 2                                              |
++------------------------------------------------+
+```
+
+#### 注意事项
+
+* 请确保 `expr1` 和 `expr2` 的数据类型兼容，否则可能导致函数执行失败。
+* 如果 `expr2` 中的所有值均为 `NULL`，函数将返回 `NULL`。
+* `MIN_BY` 函数适用于成对数据的比较和筛选，但不适用于单独的数据项。

+### WM_CONCAT 函数
+
+#### 概述
+
+`WM_CONCAT` 函数用于将一列的值通过指定的分隔符进行连接。此函数可以处理字符串类型数据，并在连接时可以选择去重或保留所有值。
+
+#### 语法
+
+```sql
+wm_concat([DISTINCT] separator, col)
+```
+
+#### 参数说明
+
+* `separator`: 字符串类型常量,作为连接值的分隔符。
+* `col`: 字符串类型,需要进行连接的列。
+
+#### 返回结果
+
+返回一个字符串类型的值，其中包含连接后的结果。如果设置了`DISTINCT`关键字,则计算去重后的集合；否则,保留所有值。`NULL`值不参与计算。
+
+#### 使用示例
+
+1. 使用&&拼接
+
+```sql
+SELECT wm_concat('&&', col) FROM VALUES ('row1'), (NULL), ('row3') AS t(col);
++----------------------+
+| wm_concat('&&', col) |
++----------------------+
+| row1&&row3           |
++----------------------+
+```
+
+2. 带分隔符的连接：
+
+```sql
+SELECT wm_concat(',', col) FROM VALUES (1), (NULL), (3) AS t(col);
++---------------------+
+| wm_concat(',', col) |
++---------------------+
+| 1,3                 |
++---------------------+
+```
+
+3. 去重连接并分组：
+
+```sql
+SELECT k, wm_concat(DISTINCT '|', v)
+FROM VALUES
+(1, 'ALLEN'),
+(1, NULL),
+(1, 'ALLEN'),
+(2, 'KING'),
+(2, 'ALEX') AS t(k, v) GROUP BY k;
++---+----------------------------+
+| k | wm_concat(DISTINCT '|', v) |
++---+----------------------------+
+| 1 | ALLEN                      |
+| 2 | KING|ALEX                  |
++---+----------------------------+
+```
+
+4. 连接时处理空格和特殊字符：
+
+```sql
+SELECT wm_concat(' - ', col) FROM VALUES ('John Doe'), ('Jane Smith'), (NULL), ('Alice Jones') AS t(col);
++-------------------------------------+
+|        wm_concat(' - ', col)        |
++-------------------------------------+
+| John Doe - Jane Smith - Alice Jones |
++-------------------------------------+
+```
+
+#### 注意事项
+
+* 当`col`列中的值为`NULL`时,`WM_CONCAT`函数不会将其包含在结果中。
+* 如果需要连接的列中包含空格或特殊字符，请确保使用适当的分隔符以避免歧义。
+* 使用`DISTINCT`关键字可以有效地去除重复的字符串值,但请注意,这可能会影响性能。在处理大量数据时,请谨慎使用此选项。

+BITMAP_AND 函数用于计算两个 bitmap 类型数据的交集。该函数接受两个 bitmap 类型的参数，并返回一个新的 bitmap 类型结果，其中包含两个输入 bitmap 的共同元素。
+
+#### 参数说明
+* `left`：第一个 bitmap 类型参数。
+* `right`：第二个 bitmap 类型参数。
+
+#### 返回类型
+返回一个 bitmap 类型的结果。
+
+#### 使用示例
+以下示例展示了如何使用 BITMAP_AND 函数计算两个 bitmap 类型数据的交集。
+
+示例 1：
+```sql
+SELECT bitmap_and(bitmap_build(array(1, 2, 3)), bitmap_build(array(2, 3, 4)));
+```
+结果：
+```plaintext
+[2, 3] -- 结果按 array 形式演示，客户端支持 bitmap 类型打印,可以使用bitmap_to_array函数展示
+```
+
+示例 2：
+```sql
+SELECT bitmap_to_array(bitmap_and(bitmap_build(array(1, 2, 3, 5, 6)), bitmap_build(array(2, 3, 4, 6, 7))));
+```
+结果：
+```plaintext
+[2, 3, 6]
+```
+
+
+
+#### 注意事项
+* BITMAP_AND 函数要求两个输入参数都是 bitmap 类型，否则会导致函数执行失败。
+* 结果按 array 形式展示，但实际返回的是一个 bitmap 类型数据。客户端可能不支持直接打印 bitmap 类型数据，需要使用相应的转换函数（如 `bitmap_to_array`）将其转换为可打印的格式。
+* 当输入的 bitmap 类型数据中的元素数量较大时，BITMAP_AND 函数的计算效率可能受到影响。在这种情况下，可以考虑使用其他数据类型或方法进行计算。

+### BITMAP_AND_CARDINALITY 函数
+
+#### 概述
+`BITMAP_AND_CARDINALITY` 函数用于计算两个 bitmap 类型参数的集合交集，并返回结果集中的元素数量。该函数在处理大量数据时具有较高的性能优势，特别适用于需要快速计算集合关系的场景。
+
+#### 语法
+```
+bitmap_and_cardinality(left, right)
+```
+#### 参数说明
+
+* `left` (bitmap 类型): 第一个输入的 bitmap 数据。
+* `right` (bitmap 类型): 第二个输入的 bitmap 数据。
+
+#### 返回结果
+返回一个 bigint 类型的值，表示两个输入 bitmap 交集中的元素数量。
+
+#### 使用示例
+
+**示例 1**：计算两个简单 bitmap 的交集元素数量
+```sql
+SELECT bitmap_and_cardinality(bitmap_build(array(1, 2, 3)), bitmap_build(array(2, 3, 4)));
+```
+结果：
+```
+2
+```
+在这个例子中，两个 bitmap 分别为 `{1, 2, 3}` 和 `{2, 3, 4}`，它们的交集为 `{2, 3}`，因此结果为 2。
+
+**示例 2**：结合实际数据表计算交集元素数量
+假设我们有一个名为 `users` 的数据表，其中包含以下列：`id`, `username`, `interests`。`interests` 列存储了用户的兴趣爱好，数据类型为 bitmap。
+
+现在，我们想要计算喜欢“篮球”和“足球”的用户数量。可以使用以下 SQL 查询实现：
+```sql
+SELECT bitmap_and_cardinality(
+    bitmap_or(
+        bitmap_and(interests, 'basketball'),
+        bitmap_and(interests, 'football')
+    ),
+    interests
+) AS shared_interests_count
+FROM users;
+```
+在这个例子中，我们首先使用 `bitmap_and` 函数筛选出喜欢“篮球”和“足球”的用户，然后使用 `bitmap_or` 函数计算这两个集合的并集。最后，使用 `bitmap_and_cardinality` 函数计算并集中的元素数量，即喜欢“篮球”和“足球”的用户数量。
+
+#### 注意事项
+* 确保输入参数的数据类型为 bitmap，否则会导致函数执行失败。
+* 当输入的 bitmap 为空时，函数返回 0。

+### BITMAP_ANDNOT 函数
+```
+bitmap_andnot(left, right)
+```
+
+#### 功能描述
+BITMAP_ANDNOT 函数用于计算两个 bitmap 类型参数的集合差（andnot 运算），返回一个新的 bitmap 类型结果。该函数在处理大量数据时具有较高的性能优势。
+
+#### 参数说明
+* left, right: 这两个参数均为 bitmap 类型，分别表示进行集合差运算的左侧和右侧 bitmap 数据。
+
+#### 返回结果
+返回一个新的 bitmap 类型结果，其中包含左侧 bitmap 中存在但右侧 bitmap 中不存在的元素。
+
+#### 使用示例
+1. 计算两个简单 bitmap 的集合差：
+```sql
+SELECT bitmap_andnot('01', '10');
+```
+结果：`00`
+
+2. 使用数组构建 bitmap 并计算集合差：
+```sql
+SELECT bitmap_to_array(bitmap_andnot(bitmap_build(array(1, 2, 3)), bitmap_build(array(2, 3, 4))));
+```
+结果：按 array 形式表示为 `[1]`，具体客户端支持的 bitmap 打印方式可能有所不同。
+
+3. 计算两个较大规模的 bitmap 集合差：
+```sql
+SELECT bitmap_to_array(bitmap_andnot(
+  bitmap_build(array(1, 2, 3, 4, 5, 6, 7, 8, 9)),
+  bitmap_build(array(3, 4, 5, 6, 7, 8, 9, 10))
+));
+```
+结果：按 array 形式表示为 `[1, 2]`
+
+4. 在实际业务场景中，可以利用 BITMAP_ANDNOT 函数对用户兴趣标签进行筛选。例如，从兴趣标签库中排除掉某些特定用户群体不感兴趣的标签：
+```sql
+SELECT user_interests
+FROM users
+WHERE user_id = 1;
+```
+假设上述查询结果为：
+```
+user_id | user_interests
+--------+-----------------
+1       | 0000000000001111
+```
+现在我们要排除掉用户不感兴趣的标签 4 和 5：
+```sql
+SELECT bitmap_andnot(user_interests, bitmap_build(array(4, 5)))
+FROM users
+WHERE user_id = 1;
+```
+结果：
+```
+user_id | user_interests
+--------+-----------------
+1       | 0000000000000101
+```
+通过 BITMAP_ANDNOT 函数，我们成功地从用户兴趣标签中排除了不感兴趣的标签 4 和 5。

+### BITMAP_ANDNOT_CARDINALITY 函数
+
+
+#### 功能描述
+BITMAP_ANDNOT_CARDINALITY 函数用于计算两个 bitmap 类型参数的集合差（即 ANDNOT 操作），并返回结果 bitmap 中元素的数量。该函数在处理大规模数据集时，能够高效地进行集合操作，尤其适用于需要快速计算集合之间关系的场景。
+
+#### 函数语法
+```
+bitmap_andnot_cardinality(left, right)
+```
+* left: 第一个 bitmap 参数。
+* right: 第二个 bitmap 参数。
+
+#### 返回类型
+返回一个 bigint 类型的值，表示结果 bitmap 中元素的数量。
+
+#### 使用示例
+以下示例展示了如何使用 BITMAP_ANDNOT_CARDINALITY 函数来计算两个 bitmap 的集合差，并获取结果中元素的数量。
+
+**示例 1**：计算两个简单 bitmap 的集合差
+```sql
+SELECT bitmap_andnot_cardinality(
+    bitmap_build(array(1, 2, 3)),
+    bitmap_build(array(2, 3, 4))
+);
+```
+结果：
+```
+1
+```
+在这个例子中，第一个 bitmap 包含元素 1、2 和 3，第二个 bitmap 包含元素 2、3 和 4。集合差操作后，结果 bitmap 只包含第一个 bitmap 中存在但第二个 bitmap 中不存在的元素，即只包含元素 1，因此结果为 1。
+
+**示例 2**：在实际数据表中应用 BITMAP_ANDNOT_CARDINALITY 函数
+假设我们有一个名为 `orders` 的数据表，其中包含以下列：`order_id`、`customer_id` 和 `order_date`。我们想要找出在特定日期范围内，某个特定客户没有下过的订单数量。
+
+```sql
+SELECT customer_id,
+       bitmap_andnot_cardinality(
+           bitmap_union(
+               -- 构建特定日期范围内所有订单的 bitmap
+               SELECT bitmap_or(
+                   bitmap_build(
+                       -- 提取每个订单的 customer_id
+                       array_agg(DISTINCT order_id)
+                   ) FROM orders
+                   WHERE order_date BETWEEN '2022-01-01' AND '2022-01-31'
+               )
+           ),
+           -- 构建特定客户所有订单的 bitmap
+           bitmap_build(
+               array_agg(DISTINCT order_id)
+           ) FROM orders
+           WHERE customer_id = 12345
+       ) AS orders_count
+FROM orders
+WHERE order_date BETWEEN '2022-01-01' AND '2022-01-31'
+GROUP BY customer_id;
+```
+在这个例子中，我们首先使用 `bitmap_union` 函数来构建特定日期范围内所有订单的 bitmap。然后，我们使用 `bitmap_build` 函数来构建特定客户所有订单的 bitmap。最后，我们使用 BITMAP_ANDNOT_CARDINALITY 函数来计算这两个 bitmap 的集合差，并返回结果中元素的数量，即该客户在特定日期范围内没有下过的订单数量。

+### BITMAP_BUILD 函数
+
+#### 概述
+`bitmap_build` 函数用于从整数类型的数组表达式（expr）构建 bitmap 类型。该函数接受一个数组作为输入，并返回一个 bitmap 类型的结果。
+
+#### 语法
+```
+bitmap_build(expr)
+```
+
+#### 参数
+- `expr`: `array<T>` 类型，其中 T 是整数类型。
+
+#### 返回值
+- 返回一个 bitmap 类型的结果。
+
+#### 使用示例
+1. 从包含整数 1、2、3 的数组构建 bitmap 类型：
+   ```sql
+   SELECT bitmap_build(array(1, 2, 3));
+   ```
+   结果将以数组形式展示，但实际上是一个 bitmap 类型：
+   ```
+   [1,2,3]
+   ```
+   
+2. 将上述结果转换回数组形式以验证其内容：
+   ```sql
+   SELECT bitmap_to_array(bitmap_build(array(1, 2, 3)));
+   ```
+   结果将显示为数组形式：
+   ```
+   [1,2,3]
+   ```
+
+3. 构建一个包含多个连续整数的 bitmap 类型：
+   ```sql
+   SELECT bitmap_build(array(1, 2, 3, 4, 5));
+   ```
+   结果将展示为：
+   ```
+   [1,2,3,4,5]
+   ```
+
+4. 从包含负整数和零值的数组构建 bitmap 类型：
+   ```sql
+   SELECT bitmap_build(array(-1, 0, 2, -3));
+   ```
+   结果将展示为：
+   ```
+   [-1, 0, 2, -3]
+   ```
+
+#### 注意事项
+- 客户端不支持直接打印 bitmap 类型的结果，如果直接查看 bitmap 结果会报错，因此在实际使用中如需显示，需要使用 bitmap_to_array 函数将其转化为 array。
+- 当处理大型数据集时，bitmap 类型可以提高查询性能，因为它占用的内存空间相对较小。
+
+通过以上示例和说明，您可以更好地理解如何使用 `bitmap_build` 函数从整数数组构建 bitmap 类型，并在实际应用中发挥其优势。

+   计算两个简单 bitmap 的 OR 集合：
+   ```sql
+   SELECT bitmap_or(bitmap_build(array(1, 2, 3)), bitmap_build(array(2, 3, 4)));
+   ```
+   预期结果：`[1, 2, 3, 4]` （结果以 array 形式展示，实际客户端可能不支持 bitmap 类型打印）
+
+2. **结合数组函数使用**  
+   使用 bitmap_or 函数处理数组，并转换结果为数组形式：
+   ```sql
+   SELECT bitmap_to_array(bitmap_or(bitmap_build(array(1, 2, 3)), bitmap_build(array(2, 3, 4))));
+   ```
+   预期结果：`[1, 2, 3, 4]`
+
+3. **多集合运算**

+   ```
+   预期结果：`[1, 2, 3, 4, 5]`
+
+4. **处理空值**  
+   当输入的 bitmap 之一为空时，结果将反映非空的 bitmap：
+   ```sql
+   SELECT bitmap_to_array(bitmap_or(bitmap_build(array(1, 2, 3)), NULL));
+   ```
+   预期结果：`[1, 2, 3]`
+
+#### 注意事项
+- 客户端不支持直接打印 bitmap 类型的结果，如果直接查看bitmap结果会报错，因此在实际使用中如果要屏显需要使用bitmap_to_array转化成array。
+* BITMAP_OR 函数要求两个输入参数都是 bitmap 类型，否则将返回错误。
+* 当处理大型数据集时，请注意内存使用情况，因为 bitmap 可能会占用较大的内存空间。
+
+
+通过以上示例和说明，您可以更好地理解 BITMAP_OR 函数的用途和使用方法。在实际应用中，BITMAP_OR 函数可以有效地处理和分析 bitmap 类型数据，帮助您完成复杂的数据集合运算任务。

+SELECT bitmap_xor(bitmap_build(array(-1, -2, -3)), bitmap_build(array(-2, -4, -3)));
+```
+结果：
+```
+[-1, -4]
+```
+
+### 注意事项
+* 请确保输入的两个参数都是 bitmap 类型，否则会导致函数执行失败。
+* 客户端不支持直接打印 bitmap 类型的结果，如果直接查看 bitmap 结果会报错，因此在实际使用中如果要屏显需要使用 `bitmap_to_array` 转化成 array。

+### BIT_COUNT 函数
+
+#### 概述
+`BIT_COUNT` 函数用于计算给定整数表达式中非零位的数量。该函数对于分析数据的位模式非常有用。
+
+#### 语法
+```
+BIT_COUNT(expr)
+```
+
+#### 参数
+- `expr`: 可以是任何整数类型的表达式，包括 `TINYINT`、`SMALLINT`、`INT` 和 `BIGINT`。
+
+#### 返回结果
+返回一个 `INT` 类型的值，表示输入表达式中非零位的数量。
+
+#### 使用示例
+1. 计算正整数的非零位数量：
+   ```sql
+   SELECT BIT_COUNT(100); -- 返回 3，因为二进制表示为 1100100
+   ```
+
+2. 计算负整数的非零位数量：
+   由于不同系统对负数的表示方式不同（如二进制补码），计算结果可能与预期有所差异。在 LakeHouse 中，可以通过显式转换为特定长度的整数类型来获得一致的结果。
+   ```sql
+   SELECT BIT_COUNT(-100), BIT_COUNT(CAST(-100 AS TINYINT)), BIT_COUNT(CAST(-100 AS SMALLINT)), BIT_COUNT(CAST(-100 AS INT)), BIT_COUNT(CAST(-100 AS BIGINT));
+   -- 返回 28, 4, 12, 28, 60
+   ```
+
+3. 计算不同整数类型的非零位数量：
+   ```sql
+   SELECT BIT_COUNT(CAST(123 AS TINYINT)), BIT_COUNT(CAST(123 AS SMALLINT)), BIT_COUNT(CAST(123 AS INT)), BIT_COUNT(CAST(123 AS BIGINT));
+   -- 返回 4, 4, 4, 4
+   ```
+
+4. 对于包含多个整数的列，可以逐个计算它们的非零位数量：
+   ```sql
+   SELECT BIT_COUNT(col1), BIT_COUNT(col2) FROM table_name;
+   ```
+
+#### 注意事项
+- 当计算负整数的非零位数量时，请注意不同系统可能导致结果的差异。为了确保结果的一致性，建议显式指定整数类型。
+- `BIT_COUNT` 函数对正整数和负整数的计算方式可能有所不同，因此在进行比较或聚合时需要特别注意。

+
+#### 语法
+```sql
+expr1 [NOT] BETWEEN expr2 AND expr3
+```
+
+#### 参数说明
+- `expr1`: 需要判断的表达式，可以是小整数（smallint）、 tinyint、整数（int）、大整数（bigint）、浮点数（float）、双精度浮点数（double）、十进制数（decimal）、日期（date）、字符串（string）、字符（char）或可变长字符串（varchar）类型。
+- `expr2`: 范围的起始值，与 expr1 进行比较的表达式。
+- `expr3`: 范围的结束值，与 expr1 进行比较的表达式。
+- `NOT` (可选): 使用 NOT 关键字表示对结果取反，即如果 expr1 不在 expr2 和 expr3 之间，则返回 true。
+
+#### 返回结果
+返回一个布尔值（boolean），表示 expr1 是否在 expr2 和 expr3 之间。
+
+#### 使用示例
+1. 判断数字是否在指定范围内：
+   ```sql
+   > SELECT 5 BETWEEN 3 AND 7;
+   true
+   ```
+   上述示例中，数字 5 在 3 和 7 之间，所以返回 true。
+
+2. 判断字符串是否在指定范围内：
+   ```sql
+   > SELECT 'C' BETWEEN 'A' AND 'E';
+   true
+   ```
+   上述示例中，字符串 'C' 在 'A' 和 'E' 之间，所以返回 true。

+### CASE 表达式
+
+#### 1. 概述
+
+CASE 表达式是 SQL 中的一种条件选择结构，它允许基于一系列条件返回不同的结果。CASE 表达式有两种形式：基于表达式的 CASE 和基于条件的 CASE。它们都可以用于在查询中实现分支逻辑。
+
+#### 2. 基于表达式的 CASE
+
+语法：
+
+```sql
+CASE expr {WHEN opt1 THEN res1} [...] [ELSE def] END
+```
+
+功能：
+
+- 当表达式 `expr` 与某个 `optN` 相等时，返回对应的结果 `resN`。
+- 如果 `expr` 与所有 `optN` 都不相等，则返回默认值 `def`。如果没有指定 `def`，则返回 `null`。
+
+参数：
+
+- `expr`：需要比较的任意类型表达式。
+- `optN`：与 `expr` 类型相同的条件表达式，用于比较。
+- `resN`：当条件匹配时返回的结果表达式。
+- `def`：当没有匹配条件时的默认结果表达式。
+
+示例：
+
+```sql
+SELECT
+  CASE col
+    WHEN 1 THEN 'a'
+    WHEN 2 THEN 'b'
+    ELSE 'c'
+  END AS result
+FROM VALUES(1), (2), (3) AS t(col);
+```
+
+结果：
+
+```
+result
+a
+b
+c
+```
+
+#### 3. 基于条件的 CASE
+
+语法：
+
+```sql
+CASE {WHEN cond1 THEN res1} [...] [ELSE def] END
+```
+
+功能：
+
+- 当条件 `condN` 为 `true` 时，返回对应的结果 `resN`。
+- 如果所有条件都不满足，则返回默认值 `def`。如果没有指定 `def`，则返回 `null`。
+
+参数：
+
+- `condN`：布尔表达式，用于判断分支是否满足条件。
+- `resN`：当条件满足时返回的结果表达式。
+- `def`：当没有满足条件时的默认结果表达式。
+
+示例：
+
+```sql
+SELECT
+  CASE
+    WHEN col = 1 THEN 'a'
+    WHEN col = 2 THEN 'b'
+    ELSE 'c'
+  END AS result
+FROM VALUES(1), (2), (3), (4) AS t(col);
+```
+
+结果：
+
+```
+result
+a
+b
+c
+null
+```
+
+#### 4. 应用场景
+
+- 数据转换：根据不同的条件对数据进行转换或映射。
+- 分组统计：在分组统计时，根据某些条件对数据进行分类。
+- 查询优化：在查询过程中，根据条件过滤或选择需要的数据。
+
+#### 5. 注意事项
+
+- 确保 `resN` 和 `def` 的数据类型一致。
+- 在使用基于条件的 CASE 表达式时，确保所有条件互斥，避免产生歧义。
+- 在实际应用中，根据具体需求选择合适的 CASE 表达式形式。

+### COALESCE 函数
+
+#### 概述
+
+`COALESCE` 函数用于返回其参数列表中第一个非空（non-null）的表达式值。如果所有参数都是空值（null），则返回空值（null）。
+
+#### 语法
+
+```sql
+COALESCE(expr1 [, ...])
+```
+
+#### 参数
+
+* `exprN`: 待验证的表达式，参数数量可变，但至少需要一个。参数类型可以不同，返回值类型与第一个非空参数的类型相同。
+
+#### 返回值
+
+* 返回参数列表中第一个非空的表达式值，如果所有参数均为空值，则返回空值（null）。
+
+#### 使用示例
+
+**示例 1：基本使用**
+
+```sql
+ SELECT COALESCE(null, 'A', null, 'B', 'C') as res;
++-----+
+| res |
++-----+
+| A   |
++-----+
+```
+
+在此示例中，`COALESCE` 函数返回第一个非空参数 `'A'`。
+
+**示例 2：处理多个可能为空的字段**
+
+```sql
+SELECT COALESCE(column1, column2, column3) AS non_null_value
+FROM table_name;
+```
+
+假设 `column1`、`column2` 和 `column3` 均有可能包含空值。此查询将返回这三个字段中的第一个非空值。
+
+#### 注意事项
+
+* `COALESCE` 函数在处理参数时，一旦找到第一个非空值，就会停止检查后续参数。
+* 当所有参数均为空值时，`COALESCE` 函数返回空值（null），不会引发错误。
+* 在比较参数值时，`NULL` 被视为等于 `NULL`，但并不被视为任何其他值，包括它自己。这意味着即使有两个 `NULL` 值，`COALESCE` 也不会将它们视为相等。

+### DECODE 函数
+```
+DECODE(expr, search1, result1 [, search2, result2,] ... [, default])
+```
+#### 功能描述
+DECODE 函数是一个条件表达式函数，它根据给定的 expr 表达式与 searchN 条件表达式的匹配结果，返回对应的 resultN 结果表达式。当 expr 与任一 searchN 相等时，返回相应的 resultN。如果 expr 与所有 searchN 都不相等，并且提供了 default 默认结果表达式，则返回 default。如果没有提供 default，则返回 null。
+
+在进行比较时，null 和 null 被认为是相等的。
+
+#### 参数说明
+- expr：任意类型的待匹配表达式。
+- searchN：与 expr 类型相同的判断条件表达式，用于与 expr 进行比较。
+- resultN：结果表达式，其类型需与 searchN 相同。
+- default（可选）：默认结果表达式，当 expr 与所有 searchN 都不相等时返回该值，类型需与 resultN 相同。
+
+#### 使用示例
+1. 基本使用：
+   ```sql
+   SELECT DECODE(3, 6, 'Lakehouse', NULL, 'SQL', 4, 'compiler');
+   -- 结果：'compiler'
+   ```
+   在这个例子中，expr 为 3，与 search1（6）不相等，但与 search2（4）相等，因此返回 result2（'compiler'）。
+
+2. 使用默认值：
+   ```sql
+   SELECT DECODE(5, 6, 'Lakehouse', NULL, 'SQL', 4, 'compiler', 'default');
+   -- 结果：'default'
+   ```
+   当 expr 为 5 时，与所有 searchN 都不相等，因此返回指定的 default 值（'default'）。
+
+3. 处理 null 值：
+   ```sql
+   SELECT DECODE(NULL, NULL, 'Lakehouse', 6, 'SQL', NULL, 'default');
+   -- 结果：'Lakehouse'
+   ```
+   在这个例子中，expr 为 null，与 search1（null）相等，因此返回 result1（'Lakehouse'）。
+
+4. 结合其他函数使用：
+   ```sql
+   SELECT DECODE(SUBSTR('Hello World', 1, 1), 'H', 'Yes', 'W', 'No', 'default');
+   -- 结果：'Yes'
+   ```
+   在这个例子中，我们使用 SUBSTR 函数获取字符串 'Hello World' 的第一个字符 'H'，然后使用 DECODE 函数判断该字符是否为 'H'。因为 expr 与 search1 相等，所以返回 result1（'Yes'）。
+

+### IF 函数
+
+#### 功能描述
+
+IF 函数是一个条件判断函数，根据提供的条件表达式（cond）来判断返回 expr1 或 expr2。当条件表达式的结果为 true 时，IF 函数返回 expr1 的值；当条件表达式的结果为 false 时，返回 expr2 的值。
+
+#### 参数说明
+
+* cond（条件表达式）：一个返回布尔值（true 或 false）的表达式。
+* expr1（表达式1）：当 cond 为 true 时，IF 函数返回该表达式的值。
+* expr2（表达式2）：当 cond 为 false 时，IF 函数返回该表达式的值。
+
+#### 返回结果
+
+IF 函数的返回类型与 expr1 和 expr2 的类型相同。
+
+#### 使用示例
+
+1. 示例 1：比较数值并返回结果
+
+```sql
+SELECT IF(a > 10, '大于10', '小于等于10') AS result FROM VALUES(5), (15), (10) AS t(a);
+
+ result    
++-----------+
+ 小于等于10 
+ 大于10     
+ 小于等于10 
+
+```
+
+2. 示例 2：判断字符串是否为空
+
+```sql
+SELECT IF(name = '', '空字符串', '非空字符串') AS result FROM VALUES('张三'), (''), ('李四') AS t(name);
+result
++-----------+
+非空字符串
+空字符串
+非空字符串
+
+```
+
+3. 示例 3：根据成绩判断等级
+
+```sql
+SELECT IF(score >= 90, '优秀', IF(score >= 60, '及格', '不及格')) AS grade FROM VALUES(85), (95), (55) AS t(score);

+### IN 运算符
+
+#### 功能描述
+IN 运算符用于检查某个指定的值（elem）是否在给定的表达式列表（expr1, expr2, ...）或查询结果中。如果 elem 与列表中的任意一个值或查询结果中的某个值相等，则返回 true，否则返回 false。
+
+#### 参数说明
+- `elem`：任意返回可比较类型的表达式。
+- `exprN`：与 `elem` 相同类型的表达式，可以有多个，用逗号分隔。
+- `query`：返回类型与 `elem` 类型相同的查询语句，当前版本仅支持查询返回一列结果。
+
+#### 返回类型
+返回值类型为布尔值（boolean）。
+
+#### 使用示例
+
+1. 检查数字 1 是否在给定的列表中（1, 2, 3）：
+   ```sql
+   SELECT 1 IN (1, 2, 3); -- 结果为 true
+   ```
+
+2. 检查字符串 "apple" 是否在水果列表中：
+   ```sql
+   SELECT 'apple' IN ('banana', 'apple', 'orange'); -- 结果为 true
+   ```
+
+3. 通过查询判断某个学生的成绩是否及格（假设成绩大于等于 60 分为及格）：
+   ```sql
+   SELECT student_id IN (SELECT student_id FROM scores WHERE score >= 60); -- 结果取决于学生的成绩数据
+   ```
+
+#### 注意事项
+- 请确保 `elem` 与 `exprN` 或 `query` 返回的类型相匹配，否则可能导致比较失败。
+- 当使用 IN 运算符与子查询一起使用时，请确保子查询仅返回一列结果。

+
+#### 返回结果
+
+* 返回任何一个 `then_N` 表达式的值，如果所有条件都不满足，则返回 `else` 表达式的值。
+
+#### 使用示例
+
+```SQL
+
+SELECT    name,
+          score,
+          multiIf (
+          score >= 90,
+          'A',
+          score >= 80,

+```sql
+SELECT name, nvl(salary, '未知') AS salary FROM employees;
+```
+
+2. 计算订单总金额，如果某个订单的金额为 NULL，则将其金额视为 0：
+```sql
+SELECT order_id, nvl(amount, 0) AS total_amount FROM orders;
+```
+
+3. 比较两个数值型字段，如果其中一个字段为 NULL，则返回另一个字段的值：
+```sql
+SELECT product_id, nvl(column1, column2) AS result FROM products;
+```
+
+4. 根据学生考试成绩判断是否及格，如果成绩为 NULL，则将其视为及格：
+```sql
+SELECT student_id, nvl(score, 60) AS adjusted_score FROM student_scores;
+```
+
+通过以上示例，您可以看到 NVL 函数在处理 SQL 查询中的 NULL 值时非常有用。它可以帮助您在数据分析和报表生成中避免因 NULL 值而产生的问题。

+### 提取函数 (EXTRACT)
+
+#### 功能描述
+提取函数 `EXTRACT(field FROM source)` 用于从给定的 `source` 中提取指定的 `field` 值。该函数可以处理不同类型的日期时间表达式，包括字符串、时间戳等。
+
+#### 参数说明
+- `field` (关键词)：需要提取的日期时间字段，具体选项如下：
+  - `YEAR`, `(Y, YEARS, YR, YRS)` - 年份
+  - `QUARTER`, `(QTR)` - 季度 (1 - 4)
+  - `MONTH`, `(MON, MONS, MONTHS)` - 月份 (1 - 12)
+  - `WEEK`, `(W, WEEKS)` - 表示一年中的第几个星期。需要注意的是，星期的计算是以星期一为开始，每年的第一个星期是该年第一个包含四天或以上的星期。在 ISO 星期的计算体系中，1 月份的最初几天可能属于前一年的第 52 或 53 周；同理，12 月份的最后几天可能属于下一年的第 1 周。例如，2005-01-02 属于 2004 年的第 53 周，2012-12-31 属于 2013 年的第 1 周。
+  - `DAY`, `(D, DAYS)` - 所属月份的第几天 (1 - 31)
+  - `DAYOFWEEK`, `(DOW)` - 所属星期的第几天，1 对应星期日，7 对应星期六
+  - `DAYOFWEEK_ISO`, `(DOW_ISO)` - 所属星期的第几天，基于ISO 8601标准，1 对应星期一，7 对应星期日
+  - `DAYOFYEAR`, `(DOY)` - 在所属年份的第几天 (1 - 365/366)

+   SELECT LAST_DAY('2020-02-05'); -- 结果为 2020-02-29
+   ```
+2. 确定时间戳的月末最后一天：
+   ```sql
+   SELECT LAST_DAY(TIMESTAMP_LTZ "2020-02-05 12:00:00"); -- 结果为 2020-02-29
+   ```
+3. 计算闰年二月的最后一天：
+   ```sql
+   SELECT LAST_DAY('2020-02-05'); -- 结果为 2020-02-29
+   ```
+   在这个例子中，由于 2020 年是闰年，二月有 29 天，所以返回的是 2020-02-29。

+### NOW 函数
+#### 简介
+`now` 函数是一个非确定性函数，用于返回当前的时间戳。在执行一个查询（query）过程中，无论调用多少次 `now` 函数，返回的时间戳都是相同的，即从查询开始的那一刻起固定下来的。
+
+#### 语法
+```
+now()
+```
+#### 参数
+无
+
+#### 返回结果类型
+`timestamp_ltz`
+
+#### 使用示例
+以下是一个简单的使用 `now` 函数的例子：
+
+```sql
+SELECT now();
+```
+
+执行上述 SQL 语句后，将返回类似于以下的结果，具体时间会根据查询执行时的实际时间而变化：
+
+```
+2022-01-01 15:17:22.098368
+```
+
+#### 更多例子
+1. 插入数据时使用当前时间戳作为记录创建时间：
+
+```sql
+INSERT INTO my_table (id, name, created_at) VALUES (1, 'John Doe', now());
+```
+
+2. 在更新数据时，使用当前时间戳作为记录最后更新时间：
+
+```sql
+UPDATE my_table SET name = 'Jane Doe', updated_at = now() WHERE id = 1;
+```
+
+3. 选择数据时，过滤出在过去 24 小时内创建的记录：
+
+```sql
+SELECT * FROM my_table WHERE created_at > now() - INTERVAL '1 day';
+```
+
+4. 比较当前时间与记录的最后更新时间，判断记录是否在最近一小时内有变动：
+
+```sql
+SELECT * FROM my_table WHERE updated_at > now() - INTERVAL '1 hour';
+```
+
+通过以上示例，您可以更好地理解 `CURRENT_TIMESTAMP` 函数在实际应用中的使用场景。

+
+```sql
+TO_DATE(expr [, fmt])
+```
+
+#### 功能描述
+TO_DATE 函数用于将字符串类型的表达式（expr）按照指定的格式（fmt）转换为日期类型。如果未提供 fmt 参数，则会根据系统默认的日期格式进行转换。如果表达式中包含非法的日期格式，则转换结果为 null。
+
+#### 参数说明
+- **expr** (string): 需要转换的字符串表达式。
+- **fmt** (string, 可选): 字符串表达式中日期的格式。如果不提供该参数，则按照系统默认的日期格式进行转换。
+
+#### 返回结果
+返回转换后的日期类型结果。
+
+#### 使用示例
+1. 将字符串转换为日期（默认格式）：
+   ```sql
+   SELECT TO_DATE('2022-02-01');
+   -- 返回结果：2022-02-01
+   ```
+2. 按照指定的格式转换字符串为日期：
+   ```sql
+   SELECT TO_DATE('01/02/2022', 'dd/MM/yyyy');
+   -- 返回结果：2022-02-01
+   ```
+3. 使用不同国家的日期格式进行转换：
+   ```sql
+   SELECT TO_DATE('02/01/2022', 'MM/dd/yyyy');
+   -- 返回结果：2022-02-01（在美国格式中，月和日颠倒）
+   ```
+4. 在转换过程中处理非法日期格式：
+   ```sql
+   SELECT TO_DATE('2022/13/01', 'yyyy/MM/dd');
+   -- 返回结果：null（因为13月不是有效的月份）
+   ```
+
+
+#### 注意事项
+- 确保输入的字符串表达式符合指定的日期格式，否则转换结果可能为 null。
+- 在处理用户输入的日期时，建议对输入值进行验证，以避免潜在的安全风险。

+### HASH_COMBINE 和 HASH_COMBINE_COMMUTATIVE 函数
+
+#### 功能描述
+`hash_combine` 函数用于将多个哈希值 h1, h2, ..., hN 组合成一个新的哈希值。该函数的特点是组合值的顺序会影响最终的哈希值。
+
+`hash_combine_commutative` 函数与 `hash_combine` 类似，也用于将多个哈希值 h1, h2, ..., hN 组合成一个新的哈希值。不同之处在于，该函数的特点是组合值的顺序不会影响最终的哈希值，即满足交换律。
+
+#### 参数说明
+* `h1`, `h2`, ..., `hN`: bigint 类型，表示要组合的哈希值。
+
+#### 返回结果
+返回一个 `bigint` 类型的值，表示组合后的哈希值。
+
+#### 使用示例
+以下示例展示了如何使用 `hash_combine` 和 `hash_combine_commutative` 函数：
+
+```sql
+-- 使用 hash_combine 函数
+SELECT hash_combine(1, 2, 3) AS hash_combine_result1;
+-- 结果：175247765312
+
+SELECT hash_combine(3, 2, 1) AS hash_combine_result2;
+-- 结果：175247756320
+
+-- 使用 hash_combine_commutative 函数
+SELECT hash_combine_commutative(1, 2, 3) AS hash_commutative_result1;
+-- 结果：10777284388
+
+SELECT hash_combine_commutative(3, 2, 1) AS hash_commutative_result2;
+-- 结果：10777284388
+```
+
+从上述示例中可以看出，`hash_combine` 函数在组合值的顺序改变时，结果也会发生变化；而 `hash_combine_commutative` 函数在组合值的顺序改变时，结果保持不变。
+
+#### 注意事项
+* 当需要组合的哈希值数量较少时，可以使用这两个函数。但如果需要合并大量的哈希值，建议使用其他方法，以避免性能问题。
+* 在实际应用中，可以根据具体需求选择合适的函数。如果对组合值的顺序有要求，可以使用 `hash_combine` 函数；如果对顺序无要求，可以使用 `hash_combine_commutative` 函数。

+### HASH_COMBINE_COMMUTATIVE
+```sql
+hash_combine_commutative(value1, value2, ...)
+```
+#### 功能
+对多个值进行可交换的哈希组合。与普通的 `hash_combine` 不同，`hash_combine_commutative` 的结果不受参数顺序影响，即 `hash_combine_commutative(a, b, c)` 与 `hash_combine_commutative(c, b, a)` 的结果相同。该函数常用于需要对无序集合进行哈希计算的场景。
+
+#### 参数
+* `value1`, `value2`, ...: 任意类型，待组合哈希的值，至少需要一个参数
+
+#### 返回结果
+* `bigint` 类型
+* 返回所有输入值的可交换哈希组合结果
+* 结果与参数顺序无关
+
+#### 举例
+```sql
+-- 参数顺序不影响结果
+> SELECT hash_combine_commutative(1, 2, 3);

+         );
+-7258238779908172255	-7258238779908172255
+```
+
+#### 说明
+* `hash_combine_commutative` 是可交换的（commutative），即参数顺序不影响结果
+* 与 `hash_combine` 的区别：`hash_combine` 考虑参数顺序，`hash_combine_commutative` 不考虑参数顺序
+* 常用于计算无序数据结构（如 `set`、`bitmap`、`map`）的哈希值
+* 该函数与 `general_murmurhash3` 配合使用，可以实现复杂数据结构的哈希计算
+* 适用于需要对集合进行去重或比较的场景，因为集合中元素的顺序通常不重要

+### 高阶函数
+高阶函数是那些接受一个或多个 lambda 函数作为参数的函数。在 SQL 语言中，lambda 函数通常用于处理数组、映射等复杂数据类型，以及在子查询中进行计算。
+
+#### Lambda 函数语法
+Lambda 函数的语法格式为 `arg -> expr` 或者 `(arg1, arg2) -> expr`：
+1. `->` 左侧为参数列表，可以表示数组中的元素，也可以表示映射中的键值对。参数绑定的具体含义取决于高阶函数的语义。
+2. `->` 右侧为 lambda 函数的计算体，即对形参的计算。在表达式 `expr` 中，可以引用外部查询或子查询中的列名。
+
+#### 使用示例
+1. 数组元素处理：
+``` sql
+SELECT transform(array(1, 2, 3), x -> x + 1);
+-- 结果：[2, 3, 4]
+```
+上述示例中，我们对数组 `[1, 2, 3]` 中的每个元素 `x` 应用 lambda 函数 `x -> x + 1`，得到新数组 `[2, 3, 4]`。
+
+2. 映射元素处理：
+``` sql
+SELECT transform(map('a', 1, 'b', 2), (k, v) -> k || ' : ' || v);
+-- 结果：{'a' : 'a : 1', 'b' : 'b : 2'}
+```
+在这个例子中，我们对映射 `{'a' : 1, 'b' : 2}` 中的每个键值对 `(k, v)` 应用 lambda 函数 `(k, v) -> k || ' : ' || v`，得到新的映射 `{'a' : 'a : 1', 'b' : 'b : 2'}`。
+
+3. 捕获外部列：
+``` sql
+SELECT transform(array(1, 2, 3), x -> x + a) FROM (SELECT 100 AS a) AS sub;
+-- 结果：[101, 102, 103]
+```
+在这个例子中，我们从子查询中捕获列 `a` 的值，并将其与数组 `[1, 2, 3]` 中的元素 `x` 相加，得到新数组 `[101, 102, 103]`。
+
+#### 注意事项

+返回一个新的 map<K, V> 类型数据，其中仅包含满足 lambda 表达式条件的键值对。
+
+#### 使用示例
+1. 筛选 map 中值小于等于 2 的元素：
+   <= 2);
+   // 结果：{2: "a", 1: "b"}
+   ```
+2. 筛选 map 中值小于等于 'b' 的元素：
+   ```sql
+   SELECT `map_filter`(map(2, 'a', 1, 'b', 3, 'c'), (k, v) ->
+2. 筛选 map 中值长度大于 1 的元素：
+   ```sql
+   SELECT `map_filter`(map(2, 'a', 1, 'bb', 3, 'c'), (k, v) -> LENGTH(v) > 1);

+```sql
+SELECT map_zip_with(map(1, 2, 3, 4), map(2, 3, 4, 5), (k, x, y) -> x + y);
+```
+结果：
+```
+{1:null,3:null,2:null,4:null} 
+```
+
+2. 将两个 map 中相同 key 对应的 value 转换为字符串并拼接，返回新的 map：
+```sql
+SELECT map_zip_with(map(1, "a", 2, "b"), map(1, "A", 2, "B"), (k, x, y) -> CONCAT(x, y));
+```
+结果：
+```
+{1:"aA", 2:"bB"}
+```
+
+3. 对两个 map 中相同 key 对应的 value 进行类型转换并相加，返回新的 map：
+```sql
+SELECT map_zip_with(map(1, 2), map(1, 100, 3, 300), (k, x, y) -> CAST((x + y) AS string));
+```
+结果：
+```
+{1:"102", 3:null}
+```
+
+#### 注意事项

+### FROM\_JSON 函数
+
+```sql
+from_json(json_string, schema)
+```
+
+#### 功能描述
+
+`FROM_JSON` 函数用于解析 JSON 格式的字符串（`json_string`），并根据提供的模式定义（`schema`）提取相应的数据。在解析过程中，未在模式中描述的 JSON 字段将被忽略，而模式中定义的字段若在 JSON 中不存在，则相应的字段值将被设置为 `NULL`。若 `json_string` 不是合法的 JSON 格式，函数将返回 `NULL`。
+
+模式定义的语法与建表时的语法相同，支持以下类型：
+
+1.  数组类型：`array<T>`，其中 `T` 为数组元素的类型。
+2.  键值对类型：`map<K, V>`，其中 `K` 为键的类型，`V` 为值的类型。
+3.  结构体类型：`struct<f1:T1, f2:T2, ... fn:Tn>`，其中 `f1, f2, ... fn` 为字段名，`T1, T2, ... Tn` 为字段类型。
+
+类型对应关系（JSON 类型转 LakeHouse 类型）：
+
+* JSON 对象（object）可转换为 LakeHouse 的结构体（struct）、映射（map）或字符串（string）。
+* JSON 数组（array）可转换为 LakeHouse 的数组（array）或字符串（string）。
+* 数值类型（numeric）可转换为 LakeHouse 的微秒整数（tinyint）、小整数（smallint）、整数（int）、大整数（bigint）、浮点数（float）、双精度浮点数（double）、十进制数（decimal）或字符串（string）。
+* 布尔类型（boolean）可转换为 LakeHouse 的布尔值（boolean）或字符串（string）。
+* 字符串类型（string）可转换为 LakeHouse 的字符串（string）、字符（char）、可变长字符串（varchar）、二进制（binary）、日期（date）或时间戳（timestamp）。
+* JSON 的 `null` 值可转换为任意类型。
+
+对于浮点数（float、double）类型，`FROM_JSON` 函数会尽量保证解析的精度；对于十进制数（decimal）类型，能保证在定义范围内的精度。
+
+#### 参数说明
+
+* `json_string`：类型为 `string`，表示包含 JSON 字符串的文本。
+* `schema`：类型为 `string`，定义了期望提取的数据结构，可以参考建表时的语法。
+
+#### 返回类型
+
+返回值的类型与模式定义（`schema`）中描述的类型一致。
+
+#### 使用示例
+
+```sql
+-- 解析 JSON 字符串为包含整数、浮点数和日期的结构体
+SELECT from_json('{"a": 1, "b": 1.0, "c": "2020-10-10"}', 'struct<a:int, b:float, c:date>');
+-- 返回结果：{"a":1,"b":1.0,"c":"2020-10-10"}
+
+-- 解析 JSON 数组为整数数组
+SELECT from_json('[1, 2, 3]', 'array<int>');
+-- 返回结果：[1,2,3]
+
+-- 解析 JSON 对象为映射
+SELECT from_json('{"name": "Alice", "age": 25}', 'map<string, string>');
+-- 返回结果：{"name":"Alice","age":"25"}
+
+-- 解析 JSON 字符串，其中包含嵌套结构体
+SELECT from_json('{"user": {"name": "Bob", "age": 30}, "active": true}', 'struct<`user`:map<string, string>, active:boolean>');
+-- 返回结果：{"user":{"name":"Bob","age":"30"},"active":true}
+
+-- 解析 JSON 数组，其中包含嵌套数组
+SELECT from_json('[{"id": 1, "name": "Product A"}, {"id": 2, "name": "Product B"}]', 'array<struct<id:int, name:string>>');
+-- 返回结果：[{"id":1,"name":"Product A"},{"id":2,"name":"Product B"}]
+```
+
+#### 注意事项
+
+* 确保提供的 JSON 字符串是合法的，否则函数将返回 `NULL`。
+* 模式定义应与 JSON 字符串中的数据结构相匹配，否则可能导致某些字段无法正确解析。
+* 在处理浮点数和十进制数时，应注意精度可能会受到影响。
+*   在使用 `from_json` 函数从 JSON 字符串中提取指定 schema 的数据时，如果 JSON 字符串中存在大小写敏感的键，可能会导致解析错误或结果不符合预期。例如：
+    ```SQL
+     select from_json('{"A":1,"a":2}','struct<A:bigint,a:bigint>');
+    java.lang.IllegalArgumentException: not all nodes and buffers were consumed. nodes: 
+    ```
+    为了避免这种错误，推荐使用 `parse_json` 函数。`parse_json` 函数能够正确处理大小写敏感的 JSON 键，并且提供了更灵活的数据访问方式。
+    ```SQL
+    select parse_json('{"A":1,"a":2}')['A'] as res;
+    +-----+
+    | res |
+    +-----+
+    | 1   |
+    +-----+
+    select parse_json('{"A":1,"a":2}')['a'] as res;
+    +-----+
+    | res |
+    +-----+
+    | 2   |
+    +-----+
+    
+    ```

+### GET\_JSON\_OBJECT 函数
+
+#### 功能描述
+
+GET\_JSON\_OBJECT 函数用于从 JSON 格式的字符串（str）中提取特定字段的值。它接受两个参数：第一个参数是一个 JSON 格式的字符串，第二个参数是一个字符串，用于指定 JSON 对象中所需提取字段的路径。
+
+#### 语法格式
+
+```
+get_json_object(string <str>, string <path>)
+```
+
+#### 参数说明
+
+* str (string): 一个包含 JSON 格式数据的字符串。
+* path (string): 一个描述所需提取字段位置的字符串路径。可以参考[json path规范](<https://goessner.net/articles/JsonPath/>)
+    * "$" 表示根元素。
+    * ".key" 或者 "\['key']" 用来查找 JSON object 中的 key。特殊的，"\[\*]" 表示获取所有的 value，要求 key 必须用单引号。
+    * "\[index]" 用来根据 index 访问 JSON array 的元素，起始值为 0。特殊的，"\[\*]" 表示所有的元素。
+
+#### 返回值
+
+* 返回指定字段的值，类型为字符串。
+
+#### 使用示例
+
+1. 假设我们有一个 JSON 对象如下所示：
+   ```json
+   {
+     "name": "张三",
+     "age": 30,
+     "address": {
+       "city": "北京",
+       "zipcode": "100000"
+     },
+     "hobbies": ["篮球", "旅游", "阅读"]
+   }
+   ```
+   我们可以使用 GET\_JSON\_OBJECT 函数来提取 JSON 对象中的不同字段，例如：
+   * 提取名字：
+     ```sql
+     SELECT get_json_object('{"name": "张三", "age": 30, "address": {"city": "北京", "zipcode": "100000"}, "hobbies": ["篮球", "旅游", "阅读"]}', '$.name');
+     ```
+     结果：张三
+   * 提取城市：
+     ```sql
+     SELECT get_json_object('{"name": "张三", "age": 30, "address": {"city": "北京", "zipcode": "100000"}, "hobbies": ["篮球", "旅游", "阅读"]}', '$.address.city');
+     ```
+     结果：北京
+   * 提取所有爱好：
+     ```sql
+     SELECT get_json_object('{"name": "张三", "age": 30, "address": {"city": "北京", "zipcode": "100000"}, "hobbies": ["篮球", "旅游", "阅读"]}', '$.hobbies');
+     ```
+     结果：\["篮球", "旅游", "阅读"]
+
+2. 另一个例子，我们有一个 JSON 数组如下所示：
+   ```json
+   [
+     {
+       "id": 1,
+       "name": "产品A",
+       "price": 100
+     },
+     {
+       "id": 2,
+       "name": "产品B",
+       "price": 200
+     }
+   ]
+   ```
+   我们可以使用 GET\_JSON\_OBJECT 函数来提取数组中特定元素的字段，例如：
+   * 提取第一个产品的价格：
+     ```sql
+     SELECT get_json_object('[{"id": 1, "name": "产品A", "price": 100}, {"id": 2, "name": "产品B", "price": 200}]', '$[0].price');
+     ```
+     结果：100
+   * 提取所有产品的名称：
+     ```sql
+     SELECT get_json_object('[{"id": 1, "name": "产品A", "price": 100}, {"id": 2, "name": "产品B", "price": 200}]', '$[*].name');
+     ```
+     结果：\["产品A", "产品B"]
+
+通过以上示例，您可以看到 GET\_JSON\_OBJECT 函数在处理 JSON 数据时的灵活性和实用性。在实际应用中，您可以根据需要自由组合路径字符串，以提取 JSON 数据中的任意字段。

+JSON_EXTRACT 函数系列旨在从 JSON 格式的数据中提取特定元素。这些函数根据提供的 JSON 路径（json_path）从 JSON 对象或数组中提取信息，并将结果返回为相应的数据类型。当指定的元素不存在时，函数返回 NULL。
+
+#### JSON 路径规范
+JSON 路径是一种简洁的查询语法，用于访问 JSON 数据结构中的元素。以下是一些常用的 JSON 路径符号：
+
+- `$`：表示根元素。
+- `.key` 或 `[key]`：用于查找 JSON 对象中的键（key）。特别地，`[*]` 表示获取所有键对应的值。
+- `[index]`：用于根据索引（index）访问 JSON 数组的元素，索引从 0 开始。特别地，`[*]` 表示获取数组中的所有元素。
+
+#### 函数列表
+- `json_extract(json, json_path)`：从 JSON 数据中提取指定的元素，并返回 JSON 格式的结果。
+- `json_extract_boolean(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为布尔值（BOOLEAN）。
+- `json_extract_int(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为整数（INT）。
+- `json_extract_bigint(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为大整数（BIGINT）。
+- `json_extract_float(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为浮点数（FLOAT）。
+- `json_extract_double(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为双精度浮点数（DOUBLE）。
+- `json_extract_string(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为字符串（STRING）。
+- `json_extract_date(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为日期（DATE）。
+- `json_extract_timestamp(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为时间戳（TIMESTAMP）。
+
+#### 参数说明
+- `json`：要处理的 JSON 类型数据。
+- `json_path`：用于指定要提取元素的 JSON 路径的字符串。
+
+#### 返回结果
+- 对于 `json_extract_json` 函数，返回提取到的 JSON 格式数据。
+- 对于其他函数（如 `json_extract_boolean` 等），返回提取到的数据转换为指定数据类型的值。
+
+#### 使用示例
+1. 提取 JSON 对象中的嵌套元素：
+   ```sql
+   SELECT json_extract(json'{"a": {"b": 1}}', '$.a');
+   -- 输出：{"b":1}
+   ```
+
+2. 提取 JSON 对象中带有点的键：
+   ```sql
+   SELECT json_extract(json'{"key": 1, "key.with.dot": 2}', '$.key'),
+         json_extract(json'{"key": 1, "key.with.dot": 2}', "$['key.with.dot']");
+   -- 输出：1       2
+   ```
+
+3. 提取 JSON 数组中的所有元素：
+   ```sql
+   SELECT json_extract(json'[1, 2, 3]', '$[*]');
+   -- 输出：[1,2,3]
+   ```
+
+4. 将提取到的 JSON 元素转换为整数：
+   ```sql
+   SELECT json_extract_int(json'{"a": {"b": 1}}', '$.a.b');
+   -- 输出：1
+   ```
+
+5. 将提取到的 JSON 元素转换为布尔值：
+   ```sql
+   SELECT json_extract_boolean(json'{"a": {"b": 1}}', '$.a.b');
+   -- 输出：true
+   ```
+
+通过以上示例，您可以更深入地了解 JSON_EXTRACT 函数系列的使用方法和功能。这些函数为您提供了灵活且高效的方式来处理和分析 JSON 数据。

+### JSON_PARSE 函数
+
+#### 简介
+`JSON_PARSE` 函数用于将 JSON 格式的字符串解析为 JSON 类型。解析后的 JSON 类型在输出时会自动去除多余的空格，且不保证字段（field）的顺序与原始 JSON 字符串完全一致。`PARSE_JSON` 是 `JSON_PARSE` 函数的别名，两者功能相同。
+
+#### 语法
+```
+json_parse(str)
+parse_json(str)
+```
+
+#### 参数
+- `str`: 需要解析的 JSON 格式字符串。
+
+#### 返回结果
+- 返回解析后的 JSON 类型。
+
+#### 使用示例
+
+**示例 1**：解析简单的 JSON 字符串
+```sql
+SELECT json_parse('{"name": "张三", "age": 25}');
+```
+返回结果：
+```json
+{"name":"张三","age":25}
+```
+
+**示例 2**：解析嵌套的 JSON 字符串
+```sql
+SELECT json_parse('{"user":{"name":"李四","age":30},"info":{"city":"北京","country":"中国"}}');
+```
+返回结果：
+```json
+{"user":{"name":"李四","age":30},"info":{"city":"北京","country":"中国"}}
+```
+
+**示例 3**：解析包含数组的 JSON 字符串
+```sql
+select parse_json('{"fruits":["苹果","香蕉","橙子"],"vegetables":["白菜","萝卜"]}') as res;
+```
+返回结果：
+```json
+{"fruits":["苹果","香蕉","橙子"],"vegetables":["白菜","胡萝卜"]}
+```
+
+**示例 4**：解析含有数字和布尔值的 JSON 字符串
+```sql
+SELECT json_parse('{"score":85.5,true_false:true,"count":-100}');
+```
+返回结果：
+```json
+{"score":85.5,"true_false":true,"count":-100}
+```
+
+#### 注意事项
+- 确保输入的字符串为有效的 JSON 格式，否则可能导致解析失败。
+- 在处理复杂的 JSON 字符串时，请注意字符串的缩进和引号使用，以确保正确解析。

+### TO\_JSON 函数
+
+#### 概述
+
+`TO_JSON` 函数用于将指定的表达式（expr）转换为 JSON 格式的文本。该函数能够处理各种数据类型，并将它们映射到相应的 JSON 类型。这对于在 SQL 查询中处理和输出 JSON 数据非常有用。
+
+#### 类型映射关系
+
+以下是 LakeHouse 数据类型与 JSON 类型之间的对应关系：
+
+* `struct` 和 `map`：转换为 JSON 对象（object）
+* `array`：转换为 JSON 数组（array）
+* `tinyint`、`smallint`、`int`、`bigint`、`float`、`double`：转换为 JSON 数值（numeric）
+* `boolean`：转换为 JSON 布尔值（boolean）
+* `string`：转换为 JSON 字符串（string）
+* `date`、`datetime`：转换为 JSON 字符串，格式为日期或日期时间
+* `null`：转换为 JSON  null 值
+
+需要注意的是，对于 `decimal` 类型，在转换为 JSON 时会以 `double` 类型输出，可能会丢失精度。此外，对于 `map<K, V>` 类型，如果 K 不是 `string`、`char` 或 `varchar` 类型，系统会先将其转换为字符串形式，再进行输出。这是因为 JSON 对象的键（key）必须为字符串类型。
+
+#### 函数语法
+
+```
+TO_JSON(expr)
+```
+
+#### 参数说明
+
+* `expr`：任意类型的表达式。
+
+#### 返回结果
+
+* 返回类型：字符串（string）
+
+#### 使用示例
+
+以下示例展示了如何使用 `TO_JSON` 函数处理不同类型的数据：
+
+1. 将数组映射为 JSON 对象：
+   ```sql
+   SELECT TO_JSON(MAP(ARRAY(1, 2), 2));
+   -- 输出：{"[1,2]":2}
+   ```
+
+2. 将 JSON 字符串直接输出：
+   ```sql
+   SELECT TO_JSON(JSON '{"a": 1}');
+   -- 输出：{"a": 1}
+   ```
+
+3. 将结构体转换为 JSON 对象：
+   ```sql
+   SELECT TO_JSON(NAMED_STRUCT( 'id',1, 'name','John Doe' ));
+   -- 输出：{"id":1,"name":"John Doe"}
+   ```
+
+4. 将 `null` 值转换为 JSON  null：
+   ```sql
+   SELECT TO_JSON(NULL);
+   --输出空字符串
+   +---------------+
+   | TO_JSON(NULL) |
+   +---------------+
+   |               |
+   +---------------+
+   ```
+
+通过以上示例，您可以看到 `TO_JSON` 函数在处理不同类型的数据时的灵活性和实用性。这使得在 SQL 查询中处理 JSON 数据变得更加简单和高效。

+- `expr`: 需要计算反双曲余弦值的 `DOUBLE` 类型数值。
+
+#### 返回结果
+返回参数 `expr` 的反双曲余弦值，结果类型为 `DOUBLE`。
+
+#### 使用示例
+1. 计算 `2` 的反双曲余弦值：
+```
+SELECT ACOSH(2); -- 结果约为 1.3169578969248166
+```
+2. 计算 `1` 的反双曲余弦值（结果为 `0`，因为 `1` 是 `ACOSH` 函数的极小值）：
+```
+SELECT ACOSH(1); -- 结果为 0.0
+```
+3. 计算接近于 `0` 的小数值的反双曲余弦值：
+```
+SELECT ACOSH(0.0001); -- 结果约为 NaN
+```
+4. 计算负数的反双曲余弦值（结果为 `NaN`，因为 `ACOSH` 函数只接受正数参数）：
+```
+SELECT ACOSH(-1); -- 结果为 NaN
+```
+5. 在一个查询中对多个数值计算反双曲余弦值：
+```
+SELECT ACOSH(2.5), ACOSH(3.7), ACOSH(0.5); -- 结果分别约为 1.566799236972411, 1.9826969446812033和 NaN
+```
+#### 注意事项
+- `ACOSH` 函数仅接受正数参数。如果传入负数或零，将返回 `NaN`（非数值结果）。
+- 当参数值接近于 `0` 时，反双曲余弦值会变得非常大。在实际应用中，需要注意数值溢出的问题。
+- `ACOSH` 函数与 `COSH` 函数互为逆运算。`COSH` 函数用于计算双曲余弦值，而 `ACOSH` 函数用于计算其逆运算结果。

+```sql
+csc(expr)
+```
+#### 功能描述
+余割函数 `csc` 用于计算给定角度值 `expr` 的余割值。余割函数是正弦函数的倒数，即 `csc(x) = 1/sin(x)`。该函数在数学、物理和工程等领域中有广泛应用。
+
+#### 参数说明
+* `expr` (double 类型): 需要计算余割值的角度值，单位为弧度。
+
+#### 返回结果
+返回类型为 `double`，表示计算得到的余割值。
+
+#### 使用示例
+1. 计算角度值为 1 弧度的余割值：
+```sql
+SELECT csc(1);

+### LOG1P 函数
+
+#### 概述
+`LOG1P` 函数用于计算表达式 `log(1 + expr)` 的值。这个函数在数值计算中非常有用，尤其是在处理接近零的数值时，可以避免直接计算 `log` 可能导致的数值不稳定问题。
+
+#### 语法
+```
+LOG1P(expr)
+```
+
+#### 参数
+- `expr`: 需要计算其 `log(1 + expr)` 值的 double 类型数值。
+
+#### 返回结果
+返回计算结果，类型为 double。
+
+#### 使用示例
+
+1. 计算 `log1p(0)` 的值：
+   ```sql
+   SELECT LOG1P(0);
+   ```
+   结果：
+   ```
+   0.0
+   ```
+
+2. 计算一系列数值的 `log1p` 值：
+   ```sql
+   SELECT LOG1P(0.1), LOG1P(0.01), LOG1P(0.001);
+   ```
+   结果：
+   ```
+  0.09531017980432487 0.009950330853168083 9.995003330835331E-4
+   ```
+
+3. 在实际应用中，可以使用 `LOG1P` 函数来计算概率模型中的对数几率值：
+   ```sql
+   SELECT LOG1P(2) - LOG1P(1) AS log_odds;
+   ```
+   结果：
+   ```
+    0.4054651081081643
+   ```
+
+#### 注意事项
+- 当 `expr` 为负数时，`LOG1P` 函数将返回 `NULL`。
+- 在使用 `LOG1P` 函数时，应确保输入的数值不会导致计算结果超出 double 类型的范围。

+`median` 函数用于计算一组数值的中位数。中位数是将一组数值按大小顺序排列后，位于中间位置的数值。如果数值集合有偶数个元素，则中位数是中间两个数值的平均值。`median` 函数自动忽略 `NULL` 值。
+
+#### 语法
+
+```Plain
+median(col)
+```
+
+#### 参数
+
+* `col`: 需要计算中位数的列。
+
+#### 返回结果
+
+* 返回指定列的中位数。
+
+#### 使用示例
+
+```SQL
+SELECT median(col) FROM VALUES (1), (2), (2), (3), (4), (NULL) AS tab(col);
+```
+
+在这个示例中，`median` 函数计算了由 `VALUES` 子句提供的一组数值的中位数。由于 `NULL` 值被忽略，实际参与计算的数值为 `1, 2, 2, 3, 4`。这组数值按大小顺序排列后为 `1, 2, 2, 3, 4`，中间位置的数值是 `2` 和 `3`，因此返回的中位数是这两个数值的平均值，即 `2.5`。

+-- 计算 -10 除以 3 的余数
+SELECT MOD(-10, 3); -- 结果为 -1
+
+-- 计算两个整数类型的余数
+SELECT MOD(17, 5); -- 结果为 2
+
+-- 计算小数类型的余数
+SELECT MOD(12.34, 4.56); -- 结果为 3.22
+
+-- 计算 decimal 类型的余数
+SELECT MOD(10.50, 3.14); -- 结果为 1.08
+```
+
+#### 注意事项

+### MONOTONICALLY_INCREASING_ID
+```sql
+monotonically_increasing_id()
+```
+#### 功能
+生成单调递增的 ID。该函数为每一行生成一个唯一的、单调递增的 64 位整数 ID。在分布式环境中，每个分区生成的 ID 范围不重叠，确保全局唯一性。
+
+#### 参数
+* 无参数
+
+#### 返回结果
+* bigint 类型
+* 返回单调递增的唯一 ID
+* ID 从 0 开始递增
+* 在分布式环境中，不同分区的 ID 不重叠
+
+#### 举例
+```sql
+-- 基本用法
+> SELECT a, monotonically_increasing_id() as id
+  FROM VALUES (1), (2), (3), (4), (5) AS t(a);
+1	0
+2	1
+3	2
+4	3
+5	4
+
+-- 在分布式环境中使用
+> SELECT a, monotonically_increasing_id() as id
+  FROM VALUES (1), (2), (3), (4), (5), (6), (7), (8), (9), (10) AS t(a)
+  DISTRIBUTE BY a;
+1	8589934592
+2	17179869184
+3	0
+4	8589934593
+5	17179869185
+6	8589934594
+7	0
+8	8589934595
+9	17179869186
+10	8589934596
+
+-- 生成唯一的行号
+> SELECT monotonically_increasing_id() as row_id, *
+  FROM large_table;
+
+-- 为数据添加序列号
+> SELECT monotonically_increasing_id() as seq, name, age
+  FROM users
+  ORDER BY age;
+```
+
+#### 说明
+* monotonically_increasing_id 生成的 ID 具有以下特性：
+  * 唯一性：每个 ID 在结果集中唯一
+  * 单调性：ID 值单调递增（但不一定连续）
+  * 确定性：在相同的数据分布下，生成的 ID 相同
+* 在分布式环境中，ID 的生成方式：
+  * 每个分区分配一个 ID 范围
+  * 分区内的 ID 连续递增
+  * 不同分区的 ID 范围不重叠
+  * ID 的高位用于标识分区，低位用于标识分区内的行号
+* ID 的构成（64 位）：
+  * 高 33 位：分区 ID
+  * 低 31 位：分区内的行号
+  * 因此，每个分区最多可以有 2^31 - 1 行
+* 与 row_number() 的区别：
+  * monotonically_increasing_id() 在分布式环境中更高效
+  * row_number() 需要全局排序，开销较大
+  * monotonically_increasing_id() 不保证连续性
+* 注意事项：
+  * ID 不一定从 0 开始（在分布式环境中）
+  * ID 之间可能有间隙
+  * 不应依赖 ID 的具体值，只能依赖其唯一性和单调性
+  * 相同的查询在不同的执行中可能生成不同的 ID（如果数据分布改变）
+* 该函数常用于：
+  * 为表中的行生成唯一标识符
+  * 数据导出时添加序列号
+  * 临时表的主键生成
+  * 数据分区和分桶
+* 如需生成连续的行号，请使用 row_number() 窗口函数

+### PMOD 函数
+```
+pmod(expr1, expr2)
+```
+#### 功能描述
+PMOD 函数用于计算两个数值表达式之间的模运算结果，并返回结果的正值。具体来说，该函数首先计算 `expr1 % expr2`，然后将结果与 `expr2` 相加，最后再对 `expr2` 取模，从而确保返回值始终为正数。这一特性使得 PMOD 函数在处理循环或周期性问题时非常有用。
+
+#### 参数说明
+* **expr1**：一个数值类型的表达式，可以是 float、double、decimal、tinyint、smallint、int 或 bigint 类型。
+* **expr2**：与 expr1 类型相同的数值表达式。
+
+#### 返回值
+返回类型与输入参数 expr1 和 expr2 相同。
+
+#### 使用示例
+1.  计算 2 与 1.8 之间的模运算结果：
+    ```sql
+SELECT pmod(2, 1.8); -- 结果为 0.2
+```
+2.  计算 -10 与 3 之间的模运算结果，并确保返回正值：
+    ```sql
+SELECT pmod(-10, 3); -- 结果为 2
+```
+3.  对于整数和小数的混合计算，PMOD 函数同样适用：
+    ```sql
+SELECT pmod(5.5, 3); -- 结果为 2.5
+```
+4.  在处理周期性问题时，比如计算一天中剩余的时间，可以使用 PMOD 函数：
+    ```sql
+SELECT pmod(12, 24); -- 结果为 12，表示从 12:00 开始还有 12 小时
+```

+### 幂运算函数：POW
+
+#### 功能描述
+`POW` 函数用于计算一个数的指定次方，即求解 `expr1` 的 `expr2` 次幂。该函数在数学、科学和工程计算等领域有广泛的应用。
+
+#### 语法
+```
+POW(expr1, expr2)
+```
+#### 参数说明
+* `expr1`：基数，类型为双精度浮点数（double）。
+* `expr2`：指数，类型为双精度浮点数（double）。
+
+#### 返回结果
+返回值类型为双精度浮点数（double），表示 `expr1` 的 `expr2` 次方的计算结果。
+
+#### 使用示例
+1. 计算 2 的 3 次方：
+   ```sql
+   SELECT POW(2, 3); -- 结果为 8.0
+   ```
+2. 计算 5 的 2 次方：
+   ```sql
+   SELECT POW(5, 2); -- 结果为 25.0
+   ```
+3. 计算 3 的 0.5 次方（即求平方根）：
+   ```sql
+   SELECT POW(3, 0.5); -- 结果为 1.7320508075688772
+   ```
+4. 计算 10 的 5 次方除以 2 的 3 次方：
+   ```sql
+   SELECT POW(10, 5) / POW(2, 3); -- 结果为 12500.0 
+   ```
+
+#### 注意事项
+* 当 `expr2` 为负数时，表示求解 `expr1` 的负指数幂。例如，`POW(2, -3)` 计算的是 1/(2³)。
+* 当 `expr2` 为 0 时，对于任何非零的 `expr1`，结果都是 1。如果 `expr1` 为 0，则结果未定义。
+* 当 `expr1` 为负数且 `expr2` 为非整数时，结果可能是一个复数。在某些数据库系统中，这可能导致错误或返回特定的复数表示。请根据所使用的数据库系统查阅相关文档以确保正确处理。

+### 数组合并函数：arrays\_zip
+
+`arrays_zip(a1, a2, ... aN)` 是一款强大的数组处理函数，它可以将多个数组 a1、a2 至 aN 合并为一个新的数组。新数组中的每个元素是一个结构体（struct），结构体包含 N 个字段，分别对应输入数组中的第 k 个元素。如果某个数组的第 k 个元素不存在，则在结构体中填充 null 值。
+
+#### 功能描述
+
+该函数的主要作用是将多个数组按照相同的索引位置进行合并，生成一个新的数组。新数组的每个元素都是一个结构体，结构体中的字段数量与输入数组的数量相同。这种合并方式非常适合在处理多维数据时进行数据整合。
+
+#### 参数说明
+
+* `a1 ~ aN`: 需要合并的数组，数组类型为 `array<T>`，其中 T 可以是任意数据类型。
+
+#### 返回结果
+
+返回一个新的数组，数组中的每个元素都是一个结构体。结构体包含 N 个字段，分别对应输入数组中的第 k 个元素。字段名称为 `0`、`1` 至 `N-1`。
+
+#### 使用示例
+
+1. 基本使用：
+   ```sql
+   SELECT arrays_zip(array(1, 2), array(4));
+   ```
+   结果：
+   ```json
+   [{"0":1,"1":4},{"0":2,"1":null}]
+   ```
+   上述示例中，两个数组长度相同，直接合并生成一个新的数组。
+
+2. 不等长数组合并：
+   ```sql
+   SELECT arrays_zip(array(1, 2, 3), array(4, 5));
+   ```
+   结果：
+   ```json
+    [{"0":1,"1":4},{"0":2,"1":5},{"0":3,"1":null}]
+   ```
+   在这个示例中，两个数组长度不同，合并时较短的数组后面的元素会被填充为 null。
+
+3. 多数组合并：
+   ```sql
+   SELECT arrays_zip(array(1, 2), array(4, 5), array('a', 'b'));
+
+   ```
+   结果：
+   ```json
+    [{"0":1,"1":4,"2":"a"},{"0":2,"1":5,"2":"b"}]
+   ```
+   本示例中，三个数组被合并成一个新数组，每个元素都是一个包含三个字段的结构体。

+### MAP\_FROM\_ENTRIES 函数
+
+#### 功能描述
+`MAP_FROM_ENTRIES` 函数用于从数组中创建一个 map 类型。输入的数组元素需要符合 `map_entries` 函数的格式，即每个元素都是一个包含 `key` 和 `value` 属性的结构体。
+
+#### 参数说明
+* `array`: 输入参数，类型为 `array<struct<key:K, value:V>>`，表示包含多个结构体的数组，每个结构体具有 `key` 和 `value` 两个属性。
+
+#### 返回结果
+返回一个 `map<K, V>` 类型的结果，其中 `K` 表示 key 的类型，`V` 表示 value 的类型。
+
+#### 使用示例
+1. 创建一个包含两个元素的数组，每个元素都是一个结构体，结构体中包含两个属性：`key` 和 `value`。
+```sql
+SELECT MAP_FROM_ENTRIES(ARRAY(
+NAMED_STRUCT('key',1, 'value','a'),
+NAMED_STRUCT('key',2, 'value','b')
+));
+
+```
+返回结果：
+```
+{
+  1:"a",
+  2:"b"
+}
+```
+
+2. 创建一个包含三个元素的数组，元素类型为结构体，结构体中包含不同类型的 key 和 value。
+```sql
+SELECT MAP_FROM_ENTRIES(ARRAY(
+NAMED_STRUCT('key',1, 'value','apple' ),
+NAMED_STRUCT('key',2, 'value','carrot'),
+NAMED_STRUCT('key',3, 'value','dog')
+));
+
+
+```
+返回结果：
+```
+{
+  1:"apple",
+  2:"carrot",
+  3:"dog"
+}
+```
+
+注意：在上述示例中，`extra` 属性不会包含在最终的 map 中，因为我们只关心 `key` 和 `value` 属性。
+
+#### 注意事项
+* 输入数组中的每个结构体必须具有 `key` 和 `value` 两个属性，否则会导致函数执行失败。
+* key 的类型需要唯一，不能有重复的 key 值，否则后面的 key 值会覆盖前面的 key 值。

+###  MULTIMAP_FROM_ENTRIES
+``` sql
+multimap_from_entries(array)
+```
+
+#### 功能
+从 array 中创建 multimap（一个键可以对应多个值的 map）， array 格式参考 map_entries 函数。
+与 map_from_entries 不同的是，当存在重复的键时，multimap_from_entries 会将所有对应的值聚合到一个数组中，而不是报错或覆盖。
+
+#### 参数
+* array: `array<struct<key:K, value:V>>`
+
+#### 返回结果
+`map<K, array<V>>`
+
+#### 举例
+```sql
+-- 基本用法：将重复键的值聚合到数组中
+> select multimap_from_entries(array(struct(1, 'a'), struct(2, 'b'), struct(1, 'c')));
+{1:["a","c"],2:["b"]}
+
+-- 所有键都唯一的情况
+> select multimap_from_entries(array(struct(1, 'a'), struct(2, 'b'), struct(3, 'c')));
+{1:["a"],2:["b"],3:["c"]}
+
+-- 所有键都相同的情况
+> select multimap_from_entries(array(struct(1, 'a'), struct(1, 'b'), struct(1, 'c')));
+{1:["a","b","c"]}
+
+-- 空数组
+> select multimap_from_entries(array());
+{}
+
+-- 包含 null 值
+> select multimap_from_entries(array(struct(1, 'a'), struct(2, null), struct(1, 'b')));
+{1:["a","b"],2:[null]}
+
+-- 使用字符串作为键
+> select multimap_from_entries(array(struct('x', 1), struct('y', 2), struct('x', 3)));
+{"x":[1,3],"y":[2]}
+```
+
+#### 注意事项
+* 键不能为 null，否则会抛出异常
+* 值可以为 null
+* 保持键的第一次出现顺序

+
+#### 使用示例
+
+**示例 1：创建简单的命名结构体**
+```sql
+SELECT named_struct('id', 1, 'name', 'Alice');
+```
+返回结果：
+```
+{"id":1,"name":"Alice"}
+```
+
+**示例 2：结合其他函数创建复杂结构体**
+```sql
+SELECT named_struct('user', named_struct('id', 1, 'name', 'Alice'), 'created_time', '2022-01-01 10:00:00');
+```
+返回结果：
+```
+{"user":{"id":1,"name":"Alice"},"created_time":"2022-01-01 10:00:00"}
+```
+
+**示例 3：在查询中使用命名结构体**
+```sql
+SELECT id, named_struct('name', name, 'age', age) AS user_info
+FROM users;
+```
+假设 `users` 表包含 `id`, `name`, `age` 三个字段，返回结果：
+```
+id | user_info
+--- | ---------------------------------------------------------------------------------
+1  | {"name":"Alice","age":30}
+2  | {"name":"Bob","age":25}
+...
+```
+
+#### 注意事项
+- 请确保字段名 `f1, f2, ..., fN` 的值是有效的字符串，否则可能会导致函数执行失败。
+- 当字段名与已有的字段名冲突时，需要使用别名或其他方法来避免冲突。

+### SEQUENCE 函数
+
+#### 概述
+SEQUENCE 函数用于生成一个序列，该序列从起始值（start）开始，到结束值（stop）结束，并按照指定的步长（step）递增。生成的序列包含起始值和结束值。如果未提供步长参数，系统会根据起始值和结束值的大小关系自动选择默认步长。
+
+#### 功能
+- 当起始值小于结束值时，若未指定步长，默认步长为 1。
+- 当起始值大于结束值时，若未指定步长，默认步长为 -1。
+- 支持整数和时间类型的参数。
+
+#### 参数
+- start (tinyint/smallint/int/bigint): 序列的起始值。
+- stop (tinyint/smallint/int/bigint): 序列的结束值。
+- step (tinyint/smallint/int/bigint): 序列中相邻两个元素之间的差值（步长）。可选参数。若未指定，默认值为 1 或 -1，具体取决于起始值和结束值的大小关系。
+
+#### 返回结果
+返回一个与参数类型相同的数组。
+
+#### 使用示例
+1. 生成整数序列：
+   ```sql
+   SELECT sequence(-2, 2); -- 结果：[-2, -1, 0, 1, 2]
+   SELECT sequence(2, -2); -- 结果：[2, 1, 0, -1, -2]
+   SELECT sequence(-2, 2, 3); -- 结果：[-2, 1]
+   ```
+   
+2. 生成时间序列：
+   ```sql
+   SELECT sequence(timestamp '2020-10-10 00:00:00', timestamp '2020-10-15 00:00:00', interval '1 12:00:00' day to second);
+   -- 结果：[2020-10-10 00:00:00, 2020-10-11 12:00:00, 2020-10-13 00:00:00, 2020-10-14 12:00:00]
+   ```
+
+#### 注意事项
+- 当起始值和结束值相等时，无论步长为何值（只要不为 0），生成的序列都仅包含一个元素，即起始值本身。
+- 当步长为 0 时，SEQUENCE 函数将报错。

+```sql
+SELECT STRUCT_UPDATE(named_struct('a', 1, 'b', 2), 'a', 'hello');
+```
+执行结果为：
+```json
+{"a":"hello", "b":2}
+```
+
+2. 同样，我们也可以将字段 `"b"` 的值更新为字符串 `"hello"`：
+```sql
+SELECT STRUCT_UPDATE(named_struct('a', 1, 'b', 2), 'b', 'hello');
+```
+执行结果为：
+```json
+{"a":1, "b":"hello"}
+```
+
+3. 除了字符串，我们还可以使用其他类型的表达式来更新字段值，例如将字段 `"a"` 的值更新为当前时间戳：
+```sql
+SELECT STRUCT_UPDATE(named_struct('a', 1, 'b', 2), 'a', TIMESTAMP "2023-04-01 12:00:00");
+```
+执行结果为：
+```json
+{"a":2023-04-01 12:00:00, "b":2}
+```
+
+通过以上示例，您可以看到 `STRUCT_UPDATE` 函数在更新结构体字段时非常灵活且易于使用。

+# TRANS\_ARRAY 函数
+
+## 函数描述
+
+`TRANS_ARRAY` 是一个用户自定义表值函数（UDTF），用于将一行数据转换为多行数据。它将列中存储的以固定分隔符格式分隔的数组转换为多行，实现"行转列"的数据变换。该函数特别适合处理那些将多个值存储在单个字符串字段中的数据结构。
+
+### 核心特性
+
+* **行转列转换**：将单行中用分隔符分隔的多个值拆分为多行
+* **灵活的 Key 列**：支持指定一个或多个列作为 Key，这些列不参与拆分
+* **自动补全**：当数组长度不相等时，自动用 NULL 填充较短的数组
+* **分隔符可配置**：支持任意字符串作为分隔符
+
+## 语法
+
+```sql
+trans_array(<num_keys>, <separator>, <key1>, <key2>, ..., <col1>, <col2>, <col3>)AS (<key1>, <key2>, ..., <col1>, <col2>)
+```
+
+## 参数说明
+
+| 参数              | 类型     | 必填 | 说明                                                              |
+| ----------------- | -------- | ---- | --------------------------------------------------------------- |
+| num\_keys         | BIGINT   | 是   | 转置时作为 Key 的列的个数。必须为常量，值必须 ≥ 0。Key 列必须位于所有待转置列之前。                 |
+| separator         | STRING   | 是   | 用于将字符串拆分成多个元素的分隔符。必须为常量，不能为空字符串，否则返回错误。                          |
+| key1, key2, ...   | 任意类型 | 是   | 转置时作为 Key 的列，个数由 num\_keys 指定。Key 列在结果中保持原有数据类型。                 |
+| col1, col2, ...   | STRING   | 是   | 要转为行的数组列。这些列必须为 STRING 类型，存储的内容是字符串格式的数组，例如 `item1;item2;item3`。 |
+
+### 特殊说明
+
+* **Key 列的作用**：Key 列用于分组和标识，拆分过程中 Key 列的值保持不变
+
+* **转置列要求**：Key 之后的所有列都视为待转置的数组列，必须为 STRING 类型
+
+* **输出行数**：以长度最长的数组为准，其他较短数组不足的位置用 NULL 填充。
+
+* **输出类型**：Key 列保持原有类型，其余所有列为 STRING 类型
+
+
+## 返回值
+
+返回转置后的多行数据，其中：
+
+* Key 列的数据类型保持不变
+* 转置后的列全部为 STRING 类型
+* 新的列名由 AS 子句指定
+
+## 使用示例
+
+**示例 1：单 Key 的基础转置**
+
+场景描述：用户登录表中，每个用户有多条登录 IP 和时间信息，存储为用分隔符分隔的字符串。需要将其拆分为多行以便于分析。
+
+原始数据表：`test_user_login`
+

+## 功能概述
+
+`MAX_PT` 用于获取分区表中最大分区的值。该函数特别适用于处理分区表，可以帮助用户快速定位到最新的数据分区。
+
+## 命令格式
+
+```SQL
+max_pt('schema_name.table_name'｜ 'table_name')
+```
+
+## 参数说明
+
+* **schema\_name.table\_name**: 这是一个必填参数，类型为 STRING。支持 `schema_name.table_name` 或 `table_name` 形式。如果不指定 schema，则默认使用当前上下文环境。
+
+## 返回值说明
+
+* 该函数返回最大的一级分区的值。
+
+## 示例
+
+示例 1：基本使用
+
+假设 `tbl` 是一个分区表，其对应的分区为 `20120901` 和 `20120902`，并且这两个分区中都有数据。以下语句中，`max_pt` 返回的值为 `'20120902'`。
+
+```SQL
+SELECT * FROM tbl WHERE pt = max_pt('tbl');
+```
+
+等效于以下语句：
+
+```SQL
+SELECT * FROM tbl WHERE pt = (SELECT MAX(pt) FROM tbl);
+```
+
+示例 2：多级分区场景
+
+在多级分区的场景中，可以使用标准 SQL 获取最大分区下的数据。
+
+```SQL
+SELECT * FROM table WHERE pt1 = (SELECT MAX(pt1) FROM table) AND pt2 = (SELECT MAX(pt2) FROM table WHERE pt1 = (SELECT MAX(pt1) FROM table));
+```

+## MATCH\_ALL
+
+```SQL
+MATCH_ALL(inverted_column,query, option) 
+```
+
+### 功能说明
+
+只有构建了倒排索引的列才能使用该函数，用于匹配所有内容。首先分析（analyze）查询字符串，忽略大小写，然后根据分词结果构建查询，最终返回查询结果。例如，查询字符串是“Microsoft Azure Party”，被分析器分词之后，产生三个小写的单词：microsoft、azure 和 party。然后根据分析的结果构造一个布尔查询。默认情况下，引擎内部执行的查询逻辑是：只要 eventname 字段值中包含 microsoft、azure 和 party 这三个单词，那么就返回该行数据。
+
+### 参数说明
+
+* **inverted_column**: 已构建倒排索引的列。
+* **query**: 您想要搜索的文本字符串。
+* **option**: 此参数是必填项，用于指定分词设置。它必须与构建该倒排索引时使用的分词方法相同。支持 `auto` 参数，该参数会自动与 `inverted_column` 中的分词设置进行匹配，例如：`map('analyzer', 'auto')`。
+
+### 返回结果
+
+boolean类型
+
+### 案例
+
+* 案例一
+
+```SQL
+ select match_all('a b c', 'b a', map('analyzer', 'english')) as res;

+1. 将多个数组元素组合成一个新的数组。
+2. 将多个字符串拼接成一个新的字符串。
+3. 将多个二进制数据拼接成一个新的二进制数据。
+
+#### 语法
+```
+CONCAT(array1, array2, ..., arrayN)
+CONCAT(str1, str2, ..., strN)
+CONCAT(binary1, binary2, ..., binaryN)
+```
+
+#### 参数
+- `array1 ~ arrayN`: `array<T>` 类型，表示要连接的数组。
+- `str1 ~ strN`: `string` 类型，表示要连接的字符串。
+- `binary1 ~ binaryN`: `binary` 类型，表示要连接的二进制数据。
+
+#### 返回结果

+- 二进制重载版本：返回一个连接后的二进制数据。
+
+#### 示例
+1. 连接两个数组：
+```sql
+SELECT CONCAT(array(1, 2), array(3, 4));
+```
+结果：
+```
+[1, 2, 3, 4]
+```
+
+2. 连接多个字符串：
+```sql
+SELECT CONCAT('hello', '-', 'world');
+```
+结果：
+```
+hello-world
+```
+
+3. 连接两个二进制数据：
+```sql
+SELECT CONCAT(CAST('123' AS BINARY), CAST('456' AS BINARY));
+```
+结果：
+```
+[31 32 33 34 35 36] 
+```
+
+4. 连接字符串和数字（注意：数字需要先转换为字符串）：
+```sql
+SELECT CONCAT('The price is ', CAST(100 AS STRING), ' dollars.');
+```
+结果：
+```
+The price is 100 dollars.
+```
+

+### CONCAT_WS 函数
+
+#### 概述
+`CONCAT_WS` 函数用于将多个字符串或数组中的字符串元素连接成一个字符串。它可以根据指定的分隔符 `sep` 来连接输入的字符串或数组中的字符串元素。如果输入的字符串为 `NULL`，则在结果中忽略该值。
+
+#### 语法
+```
+CONCAT_WS(sep, str1, str2, ..., strN)
+CONCAT_WS(sep, array1, array2, ..., arrayN)
+```
+
+#### 参数
+- `sep`: 分隔符字符串，用于连接输入的各个字符串。
+- `str1, str2, ..., strN`: 要连接的字符串。
+- `array1, array2, ..., arrayN`: 包含要连接的字符串元素的数组。

+```
+结果：
+```
+hello-world
+```
+
+2. 连接多个字符串：
+```sql
+SELECT CONCAT_WS('-', 'hello', 'my', 'friend', '!');
+```
+结果：
+```
+hello-my-friend-!
+```
+
+3. 忽略 `NULL` 值：
+```sql
+SELECT CONCAT_WS('-', 'hello', NULL, 'world', NULL);
+```
+结果：
+```
+hello-world
+```
+
+4. 使用数组连接字符串：
+```sql
+SELECT CONCAT_WS('-', array('hello', 'my', 'friend'), array('is', NULL, 'awesome'));
+```
+结果：
+```
+hello-my-friend-is-awesome
+```
+
+5. 结合其他函数使用：
+```sql
+SELECT CONCAT_WS('-', UPPER('hello'), LENGTH('world'), LOWER('!'));
+```
+结果：
+```
+HELLO-5-!
+```
+
+#### 注意事项
+- 当输入的字符串或数组元素为 `NULL` 时，`CONCAT_WS` 函数会忽略这些值。
+- 如果所有输入的字符串或数组元素均为 `NULL`，则返回空字符串。
+- 如果分隔符 `sep` 为 `NULL`，则返回 NULL。
+
+通过以上示例和说明，您可以更好地理解 `CONCAT_WS` 函数的用法和功能。在实际应用中，您可以根据需要灵活地使用此函数来连接字符串或数组元素。

+5.  当 substr 为空字符串时，返回 1，因为空字符串被视为存在于任何字符串的开头。
+    ```sql
+SELECT INSTR('HelloWorld', ''); -- 结果为：1
+```
+#### 注意事项
+- 如果 str 或 substr 为 NULL，则 INSTR 函数返回 NULL。
+- 搜索是区分大小写的，即 'Hello' 和 'hello' 被视为不同的字符串。
+- 若要执行不区分大小写的搜索，可先使用 UPPER 或 LOWER 函数转换 str 和 substr 为同一大小写形式，然后再进行比较。
+
+通过以上示例和说明，您可以更好地理解 INSTR 函数的用法和功能。在实际应用中，您可以根据需要灵活地使用此函数来查找特定子字符串的位置。

+`LENGTHB` 是 SQL 中的一个函数，用于返回字符串参数的字节长度。与 `CHAR_LENGTH` 或 `CHARACTER_LENGTH` 函数不同，`LENGTHB` 计算的是字节数而不是字符数，这在处理多字节字符集（如 UTF-8）时尤其重要。
+
+## 语法
+
+```SQL
+LENGTHB(string)
+```
+
+## 参数说明
+
+* **string**: 要计算字节长度的字符串表达式。
+
+## 返回结果
+
+该函数返回一个整数，表示输入字符串中的字节总数。对于 NULL 输入，返回值也是 NULL。
+
+## 示例
+
+### 示例 1: 基本使用
+
+```SQL
+SELECT LENGTHB('Hello, World!');
+```
+
+这将返回 13。
+
+### 示例 2: 处理 NULL 值
+
+```SQL
+SELECT LENGTHB(NULL);
+```
+
+这将返回 `NULL`，因为输入参数是 NULL。
+
+### 示例 3: 中文字符
+
+```SQL
+SELECT LENGTHB('中文')
+union all
+SELECT CHARACTER_LENGTH('中文');
++---------------+
+| LENGTHB('中文') |
++---------------+
+| 3             |
+| 6             |
++---------------+
+```

+### MD5函数
+
+#### 简介
+
+MD5函数用于计算给定字符串的MD5散列值。MD5是一种广泛使用的哈希函数，它可以将任意长度的数据映射为固定长度（128位）的散列值。MD5散列值通常用于验证数据的完整性。
+
+#### 语法
+
+```
+md5(expr)
+```
+
+#### 参数
+
+* `expr`: 需要计算MD5值的字符串、字符或变长字符数据类型。
+
+#### 返回结果
+
+返回一个字符串，表示计算得到的MD5散列值。
+
+#### 使用示例
+
+1. 计算一个简单字符串的MD5值：
+
+```
+SELECT md5('hello')as res;
++----------------------------------+
+|               res                |
++----------------------------------+
+| 5d41402abc4b2a76b9719d911017c592 |
++----------------------------------+
+```
+
+2. 计算一个包含特殊字符的字符串的MD5值：
+
+```
+SELECT md5('Hello, World!') as res;
++----------------------------------+
+|               res                |
++----------------------------------+
+| 65a8e27d8879283831b664bd8b7f0ad4 |
++----------------------------------+
+```
+
+3. 计算一个中文字符串的MD5值：
+
+```
+SELECT md5('你好，世界！') as res;
++----------------------------------+
+|               res                |
++----------------------------------+
+| 5082079d92a8ef985f59e001d445ff20 |
++----------------------------------+
+```
+
+4. 计算一个包含数字的字符串的MD5值：
+
+```
+SELECT md5('12345');
++----------------------------------+
+|               res                |
++----------------------------------+
+| 827ccb0eea8a706c4c34a16891f84e7b |
++----------------------------------+
+```
+
+#### 注意事项
+
+* MD5散列值是不可逆的，即无法从散列值反推出原始数据。

+### 函数名称
+OCTET_LENGTH
+
+### 功能描述
+OCTET_LENGTH 函数用于计算字符串（string）或二进制数据（binary）的字节长度。该函数在处理文本数据时非常有用，尤其是在需要确定数据大小或进行字符编码转换时。
+
+### 语法
+```
+OCTET_LENGTH(expr)
+```
+其中，`expr` 是一个字符串或二进制数据类型的表达式。
+
+### 参数
+- `expr`: 需要计算字节长度的字符串或二进制数据。
+
+### 返回结果
+返回一个整数，表示输入数据的字节长度。
+
+### 使用示例
+1. 计算英文字符串的字节长度：
+   ```sql
+   SELECT OCTET_LENGTH('HelloWorld'); -- 结果为 10
+   ```
+   上述示例中，字符串 "HelloWorld" 包含 10 个字符，因此返回的字节长度为 10。
+
+2. 计算中文字符串的字节长度：
+   ```sql
+   SELECT OCTET_LENGTH('你好'); -- 结果为 6
+   ```
+   由于中文字符在 UTF-8 编码下通常占用 3 个字节，字符串 "你好" 包含 2 个中文字符，因此返回的字节长度为 6。
+
+3. 计算二进制数据的字节长度：
+   ```sql
+   SELECT OCTET_LENGTH(X'48656C6C6F20576F726C64'); -- 结果为 20
+   ```
+   上述示例中，十六进制字符串 "48656C6C6F20576F726C64" 解码后对应于 ASCII 编码的字符串 "Hello World"，占用 11 个字节。
+
+4. 在查询中使用 OCTET_LENGTH 函数：
+   ```sql
+   SELECT username, OCTET_LENGTH(password) as password_length
+   FROM users;
+   ```
+   在此示例中，我们从用户表中选择用户名和密码的字节长度。这可以帮助我们了解数据存储大小或密码的复杂度（结合其他因素）。
+
+### 注意事项
+- 当处理多字节字符集（如 UTF-8）时，字符的实际字节长度可能与字符数不同。
+- 在比较字符串长度时，务必注意字符编码和字节顺序的影响。

+### RLIKE 函数
+#### 概述
+RLIKE 函数用于检查一个字符串（str）是否符合给定的正则表达式（regex）。如果符合，则返回 true，否则返回 false。该函数使用 [re2](https://github.com/google/re2) 正则表达式引擎进行匹配。
+
+#### 语法
+```
+str [not] rlike regex
+
+rlike(str, regex)
+```
+#### 参数
+* str (string)：待匹配的字符串。
+* regex (string)：正则表达式。请注意，由于 SQL 解析器会对字符串常量进行转义，因此在使用常量指定正则表达式时需要使用双反斜杠（例如：'^\\\\abc$'）。
+
+#### 返回结果
+返回一个布尔值（boolean），表示 str 是否符合 regex。
+
+#### 使用示例
+1. 检查字符串 "100-500" 是否符合正则表达式 `\d+-\d+`（数字加短横线加数字）：
+```sql
+SELECT '100-500' RLIKE '\d+-\d+';
+```
+结果：
+```
+true
+```
+
+2. 使用函数形式检查字符串 "100-500" 是否符合正则表达式 `\d+-\d+`：
+```sql
+SELECT RLIKE('100-500', '\d+-\d+');
+```
+结果：
+```
+true
+```
+
+3. 检查字符串 "\\abc" 是否符合正则表达式 `^\\\\abc$`（匹配以 "abc" 开头和结尾的字符串，正则表达式本身可能包含反斜杠进行转义）：
+```sql
+SELECT RLIKE('\\abc', '^\\\\abc$');
+```
+结果：
+```
+true
+```
+
+4. 检查字符串 "abc" 是否**不符合**正则表达式 `^\\d+$`（以数字开头和结尾的字符串）：
+```sql
+SELECT 'abc' RLIKE '^\\d+$';
+```
+结果：
+```
+false
+```
+
+5. 使用 "not" 关键字检查字符串 "123" 是否**不符合**正则表达式 `\d+`（包含数字的字符串）：
+```sql
+SELECT '123' NOT RLIKE '\d+';
+```
+结果：
+```
+false
+```
+
+通过以上示例，您可以更好地理解 RLIKE 函数的用法和功能。在实际应用中，您可以根据需要使用不同的正则表达式来匹配和验证字符串。

+### 右侧填充函数 RPAD
+
+``` sql
+rpad(str, len[, pad])
+```
+
+#### 功能描述
+RPAD 函数用于对字符串进行右侧填充。它在给定的字符串 `str` 右侧添加指定的 `pad` 字符串，直到总长度达到 `len`。如果 `len` 小于字符串 `str` 的长度，函数将截断原字符串至 `len` 长度并返回。若 `len` 小于 1，函数返回空字符串。若未指定 `pad` 字符串，则默认使用空格字符（' '）作为填充字符。
+
+#### 参数说明
+- `str`: 输入的字符串。
+- `len`: 目标总长度。
+- `pad` (可选): 用于填充的字符串，默认为一个空格字符（' '）。
+
+#### 返回结果
+返回一个新的字符串，长度为 `len`，右侧填充了 `pad` 字符串。
+
+#### 使用示例
+1. 基础用法：在字符串右侧添加指定的填充字符。
+   ```sql
+   > SELECT rpad('hello', 10, '123');
+   hello12312  
+   ```
+
+2. 当 `len` 大于 `str` 长度时，使用默认填充字符（空格）。
+   ```sql
+   > SELECT rpad('world', 12);
+   world        
+   ```
+
+3. 当 `len` 小于 `str` 长度时，截断原字符串至 `len` 长度。
+   ```sql
+   > SELECT rpad('hello world', 5);
+   hello
+   ```
+
+4. 当 `len` 小于 1 时，返回空字符串。
+   ```sql
+   > SELECT rpad('test', 0);
+   
+   ```
+
+5. 使用自定义的填充字符。
+   ```sql
+   > SELECT rpad('abc', 8, '##');
+   abc#####
+   ```
+
+#### 注意事项
+- 当 `pad` 字符串长度大于 `len` 减去 `str` 长度时，`pad` 字符串将被截断以适应目标长度。
+- 如果 `pad` 字符串为空，将使用单个空格字符作为填充字符。
+
+通过使用 RPAD 函数，您可以轻松地对字符串进行格式化和对齐操作，以满足不同的数据处理需求。

+### SHA1函数
+
+#### 简介
+
+SHA1函数用于计算给定字符串的SHA1散列值。SHA1是一种广泛使用的哈希函数，它可以将任意长度的数据映射为固定长度（160位）的哈希值。SHA1哈希值通常用于验证数据的完整性和一致性。
+
+#### 语法
+
+`sha1(expr)`
+
+#### 参数
+
+* `expr`: 需要计算SHA1值的字符串、字符或变长字符数据类型。
+
+#### 返回结果
+
+返回一个字符串，表示计算得到的SHA1哈希值。
+
+#### 使用示例
+
+1.  计算一个简单字符串的SHA1值：
+
+    ```
+SELECT sha1('hello') as res;
++------------------------------------------+
+|                   res                    |
++------------------------------------------+
+| aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d |
++------------------------------------------+
+```
+
+2.  计算一个包含特殊字符的字符串的SHA1值：
+
+    ```
+SELECT sha1('Hello, World!') as res;
++------------------------------------------+
+|                   res                    |
++------------------------------------------+
+| 0a0a9f2a6772942557ab5355d76af442f8f65e01 |
++------------------------------------------+
+```
+
+3.  计算一个中文字符串的SHA1值：
+
+    ```
+SELECT sha1('你好，世界！') as res;
++------------------------------------------+
+|                   res                    |
++------------------------------------------+
+| 6daee8a9f16b06333f100734f751d92f4e0c5a2c |
++------------------------------------------+
+```
+
+4.  计算一个包含数字的字符串的SHA1值：
+
+    ```
+SELECT sha1('12345') as res;
++------------------------------------------+
+|                   res                    |
++------------------------------------------+
+| 8cb2237d0679ca88db6464eac60da96345513964 |
++------------------------------------------+
+```
+
+#### 注意事项
+
+* SHA1哈希值是不可逆的，即无法从哈希值推导出原始数据。

+### 函数名称
+`translate` 函数
+
+### 功能描述
+`translate` 函数用于将输入字符串 `str` 中的某些字符根据指定的替换规则进行转换。具体来说，它会将 `str` 中的字符与 `from` 参数中的字符集合进行匹配，并将匹配到的字符替换为 `to` 参数中对应位置的字符。如果 `from` 中的某个字符在 `to` 中没有对应的替换字符，则在结果字符串中删除该字符。
+
+### 参数说明
+- `str` (string类型): 需要进行字符替换的原始字符串。
+- `from` (string类型): 包含需要被替换的字符集合。
+- `to` (string类型): 包含用于替换的字符集合。字符顺序应与 `from` 参数中的顺序相对应。
+
+### 返回值
+返回处理后的字符串。
+
+### 使用示例
+1. 假设我们有一个字符串 "HelloWorld"，我们想要将所有的 "l" 替换为 "b"，可以使用以下语句：
+   ```sql
+   SELECT translate('HelloWorld', 'l', 'b');
+   ```
+   执行结果为 "HebboWorbd"。
+
+2. 如果我们想要将字符串 "HelloWorld" 中的 "lo" 替换为 "ab"，可以使用以下语句：
+   ```sql
+   SELECT translate('HelloWorld', 'lo', 'ab');
+   ```
+   执行结果为 "HeaabWbrad"。
+
+3. 现在，如果我们想要将字符串 "HelloWorld" 中的 "l" 和 "o" 分别替换为 "b" 和 "n"，可以使用以下语句：
+   ```sql
+   SELECT translate('HelloWorld', 'lo', 'bn');
+   ```
+   执行结果为 "HebbnWnrbd"。
+
+4. 当 `to` 参数中的字符数量少于 `from` 参数时，多余的字符将被删除。例如，将字符串 "HelloWorld" 中的 "lo" 替换为 "a"，可以使用以下语句：
+   ```sql
+   SELECT translate('HelloWorld', 'lo', 'a');
+   ```
+   执行结果为 "HeaaWrad"。
+
+### 注意事项
+- 确保 `from` 和 `to` 参数中的字符数量相等，否则可能导致替换不完整或删除字符。
+- 如果 `to` 参数为NULL，将导致所有 `from` 返回结果也是NULL。
+- 该函数对大小写敏感，需要确保输入的字符大小写与实际需要替换的字符大小写一致。

+### TRIM 函数
+
+```
+trim(str [, trimStr])
+```
+
+#### 功能描述
+TRIM 函数用于去除字符串 `str` 左右两侧的指定字符（或空格）。如果不指定 `trimStr` 参数，则默认去除字符串左右两侧的所有空格字符。
+
+#### 参数说明
+- `str` (string): 需要进行处理的原始字符串。
+- `trimStr` (string, 可选): 指定要去除的字符集，如果省略此参数，则默认去除空格字符。
+
+#### 返回结果
+返回处理后的字符串。
+
+#### 使用示例
+1. 去除字符串两端的空格：
+   ```sql
+   > SELECT '  Hello, World!  ' AS original, TRIM(original) AS trimmed;
+    +----------------+--------+
+    | original       | trimmed |
+    +----------------+--------+
+    |  Hello, World!  | Hello, World! |
+    +----------------+--------+
+   ```
+2. 去除字符串两端的特定字符（例如星号）：
+   ```sql
+   > SELECT '**Hello, World!**' AS original, TRIM('**Hello, World!**' ,'**' ) AS trimmed;
+    +----------------+--------+
+    | original       | trimmed |
+    +----------------+--------+
+    | **Hello, World!** | Hello, World! |
+    +----------------+--------+
+   ```
+3. 去除字符串左侧的零字符：
+   ```sql
+   > SELECT '000Hello, World!' AS original, TRIM('000Hello, World!', '0' ) AS trimmed;
+    +----------------+--------+
+    | original       | trimmed |
+    +----------------+--------+
+    | 000Hello, World! | Hello, World! |
+    +----------------+--------+
+   ```
+4. 去除字符串右侧的百分号：
+   ```sql
+   > SELECT 'Hello, World!%' AS original, TRIM('Hello, World!%', '%' ) AS trimmed;
+    +----------------+--------+
+    | original       | trimmed |
+    +----------------+--------+
+    | Hello, World!% | Hello, World! |
+    +----------------+--------+
+   ```

+### TYPEOF
+```sql
+typeof(expr)
+```
+#### 功能
+返回表达式的数据类型。该函数用于查询表达式或列的类型信息，在动态 SQL 和类型检查场景中非常有用。
+
+#### 参数
+* `expr`：任意类型的表达式
+
+#### 返回结果
+* string 类型
+* 返回表达式的数据类型名称
+* 对于基本类型，返回类型名称（如 'int', 'string', 'boolean'）
+* 对于复杂类型，返回完整的类型定义（如 `array<...>`, `map<...>`, `struct<...>`）
+
+#### 举例
+```sql
+-- 基本类型
+> SELECT typeof(true);
+boolean
+
+> SELECT typeof(1);
+int
+
+> SELECT typeof(1.0);
+decimal(2,1)
+
+> SELECT typeof("1");
+string
+
+-- 复杂类型
+> SELECT typeof(array(1, 2, 3));
+array<int>
+
+> SELECT typeof(map(1, 2));
+map<int,int>
+
+> SELECT typeof(struct(1, 2, 3));
+struct<col1:int,col2:int,col3:int>
+
+```
+
+#### 说明
+* typeof 函数返回的是类型名称字符串，而不是类型对象
+* 对于 decimal 类型，返回完整的精度信息，如 'decimal(10,2)'
+* 对于复杂类型（array、map、struct），返回完整的嵌套类型定义
+* `struct` 类型的字段名默认为 `col1`、`col2`、`col3` 等
+* 该函数在编译时确定类型，不会在运行时改变
+* 常用场景：
+  * 调试和诊断
+  * 生成类型相关的元数据
+* 注意：`TYPEOF` 只返回类型信息，不包含 NULL 约束信息
+* 该函数对性能影响很小，因为类型信息在编译时就已确定

+### EXPLODE 函数
+
+#### 功能描述
+
+`EXPLODE` 函数用于将数组或映射类型的表达式展开成多行。对于数组类型的输入，元素会被逐个展开成独立的行；对于映射类型的输入，键和值会被分别展开成多行。该函数可以直接使用，也可以与 `LATERAL VIEW` 搭配使用，以实现更复杂的数据处理。
+
+#### 参数说明
+
+* `expr`：输入的数组（`array<T>`）或映射（`map<K, V>`）表达式。
+
+#### 返回结果
+
+* 对于数组类型的输入，返回的结果中每个元素的类型为 `T`。
+* 对于映射类型的输入，返回的结果中包含两个列，分别表示键（`key`）和值（`value`），它们的类型分别为 `K` 和 `V`。
+
+#### 使用示例
+
+1. 将数组类型的表达式展开成多行：
+
+```sql
+SELECT explode(array(1, 2, 3));
++-----+
+| col |
++-----+
+| 1   |
+| 2   |
+| 3   |
++-----+
+```
+
+2. 将映射类型的表达式展开成多行：
+
+```sql
+SELECT explode(map("a", 1, "b", 2, "c", 3));
++-----+-------+
+| key | value |
++-----+-------+
+| a   | 1     |
+| b   | 2     |
+| c   | 3     |
++-----+-------+
+```
+
+3. 结合 LATERAL VIEW 使用，将数组类型的表达式展开成多行，并与原始数据关联：
+
+```sql
+SELECT vt.word, lv.ex
+FROM VALUES ('hello') AS vt(word) LATERAL VIEW explode(array(5, 6)) lv AS ex;
++-------+----+
+| word  | ex |
++-------+----+
+| hello | 5  |
+| hello | 6  |
++-------+----+
+```
+
+4. 结合 LATERAL VIEW 使用，将映射类型的表达式展开成多行，并与原始数据关联：
+
+```sql
+SELECT vt.word, lv.key, lv.value
+FROM VALUES ('hello') AS vt(word) LATERAL VIEW explode(map("a", 1, "b", 2, "c", 3)) lv AS key, value;
++-------+-----+-------+
+| word  | key | value |
++-------+-----+-------+
+| hello | a   | 1     |
+| hello | b   | 2     |
+| hello | c   | 3     |
++-------+-----+-------+
+```
+
+通过以上示例，您可以看到 `EXPLODE` 函数在处理数组和映射类型数据时的灵活性和实用性。在实际应用中，您可以根据需要对输入数据进行展开操作，以便进行更深入的数据分析和处理。

+### 函数：INLINE
+
+```sql
+INLINE(expr)
+```
+
+#### 功能描述
+
+`INLINE` 函数用于将数组中的结构体元素展开成多行数据。输入参数 `expr` 为 `array<struct<T1, T2, ... Tn>>` 类型,展开后的每一列对应结构体元素中的一个字段。如果未指定列名,展开后的列名将与结构体字段名相同。`INLINE` 函数可以直接使用,也可以与 `LATERAL VIEW` 搭配使用以实现更复杂的数据处理。
+
+#### 参数说明
+
+* `expr` : 输入的数组表达式,类型为 `array<struct<T1, T2, ... Tn>>`
+
+#### 返回结果
+
+* 返回类型：根据输入参数 `expr` 进行类型推导,得到 `(T1, T2, ... Tn)` 类型的数据。
+
+#### 使用示例
+
+示例 1：简单的 INLINE 展开
+
+```sql
+SELECT INLINE(array(struct(1, 'x'), struct(2, 'y')));
++------+------+
+| col1 | col2 |
++------+------+
+| 1    | x    |
+| 2    | y    |
++------+------+
+```
+
+示例 2：与 LATERAL VIEW 搭配使用
+
+```sql
+SELECT word, s1, s2 FROM VALUES ('hello') AS vt(word) LATERAL VIEW INLINE(array(struct('a', 0), struct('b', 1))) lv AS s1, s2;
++-------+----+----+
+| word  | s1 | s2 |
++-------+----+----+
+| hello | a  | 0  |
+| hello | b  | 1  |
++-------+----+----+
+```
+
+#### 注意事项
+
+* 使用 `INLINE` 函数时,请确保输入的数组元素类型为结构体类型。
+* 在与 `LATERAL VIEW` 搭配使用时,注意为展开后的数据指定别名,以便后续操作使用。

+### JSON_TUPLE 函数
+
+#### 功能描述
+
+`JSON_TUPLE` 函数用于解析 `JSON` 字符串中的键值对,并将指定的键对应的值提取出来。该函数接受一个 `JSON` 字符串作为输入，并根据提供的键列表（`c1`、`c2`、...、`cN`）提取相应的值。如果 `JSON` 字符串解析失败，函数将返回全列为 `NULL` 的结果；如果某个键不存在于 `JSON` 对象中，对应的列将被填充为 `NULL`。需要注意的是，`JSON_TUPLE` 函数只能解析 `JSON` 对象的顶层键。
+
+该函数可以直接使用，或者与 `LATERAL VIEW` 子句结合使用，以便在更复杂的查询中提取 `JSON` 数据。
+
+#### 参数说明
+
+* `str` (string): 需要解析的 `JSON` 字符串，该字符串应为一个 `JSON` 对象。
+* `c1`, `c2`, ... `cN` (string): 需要提取的 `JSON` 对象中的键。
+
+#### 返回类型
+
+* 返回一个包含提取值的字符串数组，数量与提供的键列表长度相同。
+
+#### 使用示例
+
+**示例 1：基本用法**
+
+```sql
+SELECT json_tuple('{"x" : "1", "y" : 2}', 'x', 'z');
++------+------+
+| col0 | col1 |
++------+------+
+| 1    |      |
++------+------+
+```
+
+上述查询尝试提取键 `x` 和 `z` 的值。由于 `z` 键不存在，返回结果中 `z` 对应的值为空。
+
+**示例 2：与 LATERAL VIEW 结合使用**
+
+```sql
+SELECT a, b, c FROM VALUES ('{"a" : 1.0, "b" : 2}') AS t(word) LATERAL VIEW json_tuple(word, 'a', 'b', 'c') lv AS a, b, c;
++-----+---+---+
+|  a  | b | c |
++-----+---+---+
+| 1.0 | 2 |   |
++-----+---+---+
+```
+
+在这个例子中，我们首先创建了一个包含 `JSON` 字符串的表，然后使用 `LATERAL VIEW` 和 `json_tuple` 函数提取 `a`、`b` 和 `c` 键的值。由于 `c` 键不存在，其对应的值为空。

+
+* `expr`: 输入的数组 `array<T>` 或映射 `map<K, V>` 类型。
+
+#### 返回结果
+
+* 对于数组类型的输入,返回类型为 `int, T`。
+* 对于映射类型的输入,返回类型为 `int, K, V`。
+
+#### 使用示例
+
+1. 展开数组类型的输入：
+
+   ```sql
+   SELECT posexplode(array(1, 2, 3));
+   +-----+-----+
+   | pos | col |
+   +-----+-----+
+   | 0   | 1   |
+   | 1   | 2   |
+   | 2   | 3   |
+   +-----+-----+
+   ```
+
+2. 展开映射类型的输入：
+
+   ```sql
+   SELECT posexplode(map("a", 1, "b", 2, "c", 3));
+   +-----+-----+-------+
+   | pos | key | value |
+   +-----+-----+-------+
+   | 0   | a   | 1     |
+   | 1   | b   | 2     |
+   | 2   | c   | 3     |
+   +-----+-----+-------+
+   ```
+
+3. 结合 `LATERAL VIEW` 使用：
+
+   ```sql
+   SELECT word, pos, ex
+   FROM VALUES ('hello') AS vt(word)
+   LATERAL VIEW posexplode(array(5, 6)) lv AS pos, ex;
+   +-------+-----+----+
+   | word  | pos | ex |
+   +-------+-----+----+
+   | hello | 0   | 5  |
+   | hello | 1   | 6  |
+   +-------+-----+----+
+   ```
+
+4. 展开数组并筛选特定元素：
+
+   ```sql
+   SELECT pos, col
+   FROM posexplode(array(1, 2, 3, 4)) AS t(pos, col)
+   WHERE col % 2 = 0;
+   +-----+-----+
+   | pos | col |
+   +-----+-----+
+   | 1   | 2   |
+   | 3   | 4   |
+   +-----+-----+
+   ```
+
+5. 展开映射并计算值的总和：
+
+   ```sql
+   SELECT SUM(value) AS total_sum
+   FROM posexplode(map("a", 1, "b", 2, "c", 3)) AS t(pos, key, value);
+   +-----------+
+   | total_sum |
+   +-----------+
+   | 6         |
+   +-----------+
+   ```
+
+通过以上示例,您可以更好地理解 `posexplode` 函数的用法和功能。在实际应用中,您可以根据需要对数组或映射类型的数据进行展开和处理。

+## READ\_KAFKA
+
+## 功能描述
+
+`READ_KAFKA` 函数用于从 Apache Kafka 集群**一次性读取**数据并以表格形式返回。该函数主要用于**数据探查、测试和临时查询**场景，直接SELECT查询不会在 Kafka 中创建持久的消费者组。
+
+**语法**
+
+```SQL
+SELECT ... FROM READ_KAFKA(
+ 'bootstrap',
+ 'topic',
+'topic_pattern',
+ 'group_id', 
+'STARTING_OFFSETS', 'ENDING_OFFSETS', 'STARTING_OFFSETS_TIMESTAMP', 'ENDING_OFFSETS_TIMESTAMP', 
+'KEY_FORMAT', 
+'VALUE_FORMAT', 
+   0,
+MAP()      
+)
+```
+
+`read_kafka` 函数用于从Kafka读取数据。它支持以下参数：
+
+* **bootstrap**: Kafka服务器地址，如 `1.2.3.1:9092,1.2.3.2:9092`。
+* **topic**: Kafka主题名称，多个主题用逗号分隔，如 `topicA,topicB`。
+* **topic\_patternt**\*：topic正则，暂不支持，默认留空。如：''。\*
+* **group\_id**: Kafka消费者组ID。临时消费者组 ID，仅用于函数执行期间**不会在 Kafka 中创建持久消费者组**
+* **STARTING\_OFFSETS**: 指定读取的起始点位，默认为 `earliest`，在读取时推荐填写。
+* **ENDING\_OFFSETS**: 指定结束点位，默认为 `latest`，在读取时推荐填写。
+* **STARTING\_OFFSETS\_TIMESTAMP**: 指定起始点位的时间戳。
+* **ENDING\_OFFSETS\_TIMESTAMP**: 指定结束点位的时间戳。
+* **KEY\_FORMAT**:指定读取key的格式,类型是STRING类型忽略大小写。目前只支持raw格式
+* **VALUE\_FORMAT**：指定读取value的格式，类型是STRING类型忽略大小写。目前只支持raw格式
+* **MAX\_ERROR\_NUMBER**：读取窗口内，允许的最大错误行数。必须大于等于0。默认是 0，即不允许有错误行，取值范围0-100000
+* **MAP**()：需要传入到Kafka的参数，以kafka.开头，直接使用kafka的参数即可,可以在Kafka中找到这种选项。,格式如MAP('kafka.security.protocol', 'PLAINTEXT')，取值参考，[kafka文档](https://kafka.apache.org/documentation/#consumerconfigs)
+
+`read_kafka` 结果返回值：

+### 函数栈（STACK）
+
+#### 概述
+
+`STACK` 函数是一个强大的数据转换工具,它可以将多列表达式按照指定的行数进行堆叠,生成新的行和列。该函数在处理数据时,能够灵活地将不同类型的数据进行整合,并且可以通过 `LATERAL VIEW` 配合使用,实现更复杂的数据操作。
+
+#### 语法
+
+```sql
+STACK(n, expr1, expr2, ..., exprK)
+```
+
+#### 参数说明
+
+* `n`：整数,表示要生成的行数。
+* `expr1 ~ exprK`：要求类型相同或者可以进行隐式类型转换的表达式列表。
+
+#### 返回结果
+
+返回一个与 `expr1 ~ exprK` 相同类型的值。
+
+#### 使用示例
+
+**例子 1：基本使用**
+
+```sql
+SELECT 'hello', STACK(2, 1, 2, 3) AS (first, second), 'world';
++---------+-------+--------+---------+
+| 'hello' | first | second | 'world' |
++---------+-------+--------+---------+
+| hello   | 1     | 2      | world   |
+| hello   | 3     | NULL   | world   |
++---------+-------+--------+---------+
+```
+
+**例子 2：与 LATERAL VIEW 搭配使用**
+
+```sql
+SELECT w, x, y FROM VALUES
+('apple', 1, 2, 3, 4),
+('banana', 11, 22, 33, 44),
+('orange', 111, 222, 333, 444),
+('dog', 1111, 2222, 3333, 4444) AS t(w, a, b, c, d)
+LATERAL VIEW STACK(2, a, b, c) lv AS x, y;
++--------+------+------+
+|   w    |  x   |  y   |
++--------+------+------+
+| apple  | 1    | 2    |
+| apple  | 3    | NULL |
+| banana | 11   | 22   |
+| banana | 33   | NULL |
+| orange | 111  | 222  |
+| orange | 333  | NULL |
+| dog    | 1111 | 2222 |
+| dog    | 3333 | NULL |
++--------+------+------+
+```
+
+**例子 3：隐式类型转换**
+
+```sql
+SELECT STACK(2, 1, '2', 3) AS (col1, col2);
++------+------+
+| col1 | col2 |
++------+------+
+| 1    | 2    |

+# 功能
+
+`table_changes` 是一个用于查询 Lakehouse 表、动态表和物化视图的数据变化的表函数。通过指定一个时间区间，该函数可以返回该区间内的数据变化，无需创建表流。使用 `table_changes` 时需要确保已开启 `change_tracking` 功能。请在表上执行 `ALTER TABLE tbname SET PROPERTIES ('change_tracking'='true');` 来开启。是否可以查看的对象操作历史依赖于数据的保留周期。数据保留周期默认为七天。
+
+# 语法
+
+```SQL
+TABLE_CHANGES(table_str, start_timestamp, end_timestamp)
+```
+
+**参数要求**：
+
+* `table_str`：已存在的表、动态表或物化视图名称，需提供字符串格式。支持 'schema.tbname'、'tbname' 格式字符串。若未指定 schema，则默认使用当前 schema，即 `current_schema`。
+* `start_timestamp`：查询的时间版本起始时间，需提供标准时间戳类型表达式。
+* `end_timestamp`：查询的时间版本结束时间，需提供标准时间戳类型表达式。
+* opitons:可选参数，目前支持map('TABLE\_STREAM\_MODE', 'ORIGINAL')。当添加此参数时表示获取表变化的原始记录，未添加此参数时比如在start\_timestamp、end\_timestamp之间先insert一条记录再delete这条记录，不添加此参数将会查询不到，如果添加ORIGINAL参数则会显示insert记录和delete记录
+
+**说明**：
+
+* 指定的 `start_timestamp` 不能早于表创建时间，也不能超出数据保留周期。
+* `start_timestamp` 和 `end_timestamp` 分别表示查询的起始和结束时间。查询结果不包括 `start_timestamp` 那一刻的数据，但包括 `end_timestamp` 那一刻的数据。查询时间区间为 (start\_timestamp, end\_timestamp]，左边为开区间，右边为闭区间。
+
+# 示例
+
+示例一：查看表变化
+
+```SQL

++---------------+------------------+-------------------------+-------+-------+
+```
+
+# 注意事项
+
+1. 使用 `table_changes` 函数时，请确保已开启 `change_tracking` 功能。
+2. 指定的 `start_timestamp` 不能早于表创建时间，也不能超出数据保留周期。
+3. 查询结果不包括 `start_timestamp` 那一刻的数据，但包括 `end_timestamp` 那一刻的数据。

+
+## 功能
+`UNNEST` 是一种用于展开数组或嵌套数据结构的函数,常用于将数组类型的列转换为多行数据,以便进行行级分析。
+
+## **语法**
+```sql
+SELECT [列名] FROM UNNEST(数组表达式) [AS 别名(列名)];
+SELECT [列名] FROM 表名, UNNEST(数组列) [AS 别名(列名)]; -- 隐式 JOIN
+```
+## **参数说明**
+`数组表达式`  ：需要展开的数组或嵌套数据结构（如多维数组、结构体）。
+ `别名(列名)`：可选,为展开后的列指定别名和列名。
+`LEFT JOIN` ：可选,保留左表的所有行,即使右表（`UNNEST` 结果）无匹配数据。
+## **使用示例**
+1. **基本数组展开**
+将一维数组展开为多行,每行对应数组中的一个元素。
+**示例：**
+```sql
+-- 输入：array(1,2,3)
+SELECT * FROM UNNEST(array(1,2,3));
+-- 输出：
+-- 1
+-- 2
+-- 3
+```
+ 2. **多数组列展开**
+支持同时展开多个数组,按行对齐。若数组长度不一致,缺失值以 `NULL` 填充。
+**示例：**
+```sql
+-- 输入：array(1,2,3), array('ab','cd')
+SELECT * FROM UNNEST(array(1,2,3), array('ab','cd'));
+-- 输出：
+-- 1    ab
+-- 2    cd
+-- 3    NULL
+```
+3. **嵌套数组展开**
+支持展开多维数组（递归展开）,生成扁平化结果。
+**示例：**
+```sql
+-- 输入：array(array(1,2,3), array(4,5,6))
+SELECT * FROM UNNEST(array(array(1,2,3), array(4,5,6)));
+-- 输出：
+-- 1
+-- 2
+-- 3
+-- 4
+-- 5
+-- 6
+```
+
+4. **与 JOIN 结合使用**
+可与其他表通过 `JOIN` 或 `CROSS JOIN` 进行关联,展开数组列。
+**示例：**
+```sql
+-- 输入：表 t 包含列 k 和数组列 a
+WITH t AS (SELECT * FROM VALUES (1, array(1,2,3)), (2, array(4,5)) AS t(k, a))
+SELECT * FROM t, UNNEST(a);
+-- 输出：
+-- 1    [1,2,3]    1
+-- 1    [1,2,3]    2
+-- 1    [1,2,3]    3
+-- 2    [4,5]      4
+-- 2    [4,5]      5
+```
+
+ 5. **处理 NULL 和空数组**
+- 若数组为 `NULL`,展开后无结果。
+- 若数组为空（`[]`）,展开后同样无结果。
+**示例：**
+```sql
+-- 输入：数组列包含 NULL 或空值
+CREATE VIEW student_score AS
+SELECT id, scores FROM VALUES
+(1, [80,85,87]),
+(2, [77, NULL, 89]),
+(3, NULL),
+(4, []) AS students(id, scores);
+
+SELECT id, scores, score FROM student_score, UNNEST(scores) AS t(score);
+-- 输出：
+-- 1    [80,85,87]    80
+-- 1    [80,85,87]    85
+-- 1    [80,85,87]    87
+-- 2    [77,null,89]  77
+-- 2    [77,null,89]  NULL
+-- 2    [77,null,89]  89
+```
+6. **过滤展开结果**
+```sql
+-- 仅保留偶数元素
+WITH t AS (SELECT * FROM VALUES (1, array(1,2,3)), (2, array(4,5)) AS t(k, a))
+SELECT * FROM t LEFT JOIN UNNEST(a) u(e) WHERE u.e % 2 = 0;
+-- 输出：
+-- 1    [1,2,3]    2
+-- 2    [4,5]      4
+```
+
+
+## **注意事项**
+1. **参数类型限制**
+   `UNNEST` 仅接受数组或嵌套结构作为输入,传递非数组类型会报错。
+   ```sql
+   -- 错误示例：输入为整数
+   SELECT * FROM UNNEST(1); -- 报错：expect array type
+   ```

+
+#### 概述
+
+`AVG` 函数用于计算窗口内表达式的平均值。该函数可以应用于各种数值类型的数据，包括 `TINYINT`、`SMALLINT`、`INT`、`BIGINT`、`FLOAT`、`DOUBLE` 和 `DECIMAL`。返回结果的类型会根据输入类型进行相应的转换，`DECIMAL` 类型的结果会保留原有的精度和标度，其他类型则返回为 `DOUBLE` 类型。需要注意的是，`NULL` 值不会参与平均值的计算。
+
+#### 语法
+
+```sql
+AVG(expr) OVER ([PARTITION_clause] [ORDER_BY_clause] [FRAME_clause])
+```
+
+#### 参数说明
+
+* `expr`: 需要计算平均值的数值类型表达式。
+* `PARTITION_clause`: 可选参数，用于将数据分区，以便在每个分区内分别计算平均值。
+* `ORDER_BY_clause`: 可选参数，用于指定窗口内记录的排序方式。
+* `FRAME_clause`: 可选参数，用于定义窗口的具体范围。
+
+#### 返回结果
+
+`AVG` 函数返回一个数值，表示窗口内数据的平均值。对于 `DECIMAL` 类型，返回结果也是 `DECIMAL` 类型，其精度和标度可能会增加。其他类型的返回结果为 `DOUBLE` 类型。
+
+#### 示例
+
+1. 查询同一个部门（`dep_no`）的工资（`salary`）的平均值，按照部门开窗，不排序：
+
+```sql
+SELECT dep_no, salary, AVG(salary) OVER (PARTITION BY dep_no)
+FROM VALUES
+  ('Eric', 1, 28000),
+  ('Alex', 1, 32000),
+  ('Felix', 2, 21000),
+  ('Frank', 1, 30000),
+  ('Tom', 2, 23000),
+  ('Jane', 3, 29000),
+  ('Jeff', 3, 35000),
+  ('Paul', 2, 29000),
+  ('Charles', 2, 23000)
+AS tab(name, dep_no, salary);
++--------+--------+------------------------------------------+
+| dep_no | salary | `AVG`(salary) OVER (PARTITION BY dep_no) |
++--------+--------+------------------------------------------+
+| 3      | 29000  | 32000.0                                  |

++--------+--------+------------------------------------------+
+```
+
+2. 查询同一个部门（`dep_no`）的工资（`salary`）的累计平均值，按照部门开窗，按照工资排序。返回当前窗口中从开始行到与当前行工资相同所有行的平均值：
+
+```sql
+SELECT dep_no, salary, AVG(salary) OVER (PARTITION BY dep_no ORDER BY salary)
+FROM VALUES
+  ('Eric', 1, 28000),
+  ('Alex', 1, 32000),
+  ('Felix', 2, 21000),
+  ('Frank', 1, 30000),
+  ('Tom', 2, 23000),
+  ('Jane', 3, 29000),
+  ('Jeff', 3, 35000),
+  ('Paul', 2, 29000),
+  ('Charles', 2, 23000)

+| 2      | 29000  | 24000.0                                                      |
++--------+--------+--------------------------------------------------------------+
+```
+
+#### 注意事项
+
+* 当窗口内没有非 `NULL` 值时，`AVG` 函数返回 `NULL`。
+* 使用 `AVG` 函数时，应确保分区、排序和窗口范围的定义符合预期

+### COUNT 函数
+
+#### 概述
+
+COUNT 函数用于计算窗口内的数据行数。该函数有两种形式：`count(*)` 和 `count(expr1[,expr2...])`。`count(*)` 计算窗口内所有行的数量，包括包含 NULL 值的行；`count(expr1[,expr2...])` 计算窗口内非 NULL 表达式的数量。
+
+#### 语法
+
+```sql
+count(*) over ([partition_clause] [orderby_clause] [frame_clause])
+count(expr1[,expr2...]) over ([partition_clause] [orderby_clause] [frame_clause])
+```
+
+#### 参数
+
+* `exprN`: 任意类型，用于计算非 NULL 值的数量。
+
+#### 返回结果
+
+* 返回值类型为 bigint 类型。
+* 使用 `count(*)` 时，NULL 值也被计算为一行。
+* 使用 `count(expr1[,expr2...])` 时，任意一列出现 NULL 值，该行将被忽略。
+
+#### 示例 1：计算每个部门的人数
+
+```sql
+SELECT dep_no,name, count(*) OVER (PARTITION BY dep_no)
+FROM VALUES
+  ('Eric', 1, 28000),
+  ('Alex', 1, 32000),

+### CUME\_DIST 函数
+
+```sql
+cume_dist() OVER ([PARTITION BY column1, column2, ...] [ORDER BY column1 [ASC|DESC], column2 [ASC|DESC], ...])
+```
+
+#### 功能描述
+
+CUME\_DIST 函数用于计算当前行在指定分区中的累计分布比例。具体来说，它返回一个 double 类型的值，表示在当前行及其之前的所有行（在分区内）占整个分区行数的比例。该函数通常用于数据分析，以便了解数据在不同分组中的分布情况。
+
+#### 使用说明
+
+* PARTITION BY 子句用于将数据分为不同的分区。如果未指定 PARTITION BY 子句，则整个数据集将被视为一个分区。
+* ORDER BY 子句用于指定在每个分区内如何对数据进行排序。CUME\_DIST 函数的结果依赖于 ORDER BY 子句的排序顺序。
+* 如果 ORDER BY 列中存在相同的值，CUME\_DIST 函数将为这些行返回相同的结果，即最后一行的 row\_number() 除以窗口行数。
+
+#### 返回结果
+
+* 返回值类型为 double 类型。
+* 结果等于 `last_peer_row_number / partition_row_count`，其中 last\_peer\_row\_number 表示当前行及其之前的所有行（在分区内）的最大 row\_number() 值，partition\_row\_count 表示分区内的总行数。
+
+#### 示例
+
+```sql
+SELECT a,
+       b,
+       ROW_NUMBER() OVER(PARTITION BY a ORDER BY b) AS row_num,
+       CUME_DIST() OVER (PARTITION BY a ORDER BY b) AS cume_dist
+FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
+```
+
+结果：
+
+```
+A	b	row_num	cume_dist
+------------------------------------------------------------------------------------------
+A	1	1	0.6666666666666666
+A	1	2	0.6666666666666666
+A	2	3	1.0
+B	3	1	1.0
+```
+
+在这个示例中，我们可以看到：
+
+* 当 a = 'A' 时，有两个行（b = 1 和 b = 2），它们的 cume\_dist 分别为 0.67（2/3）和 1（3/3）。
+* 当 a = 'B' 时，只有一个行（b = 3），它的 cume\_dist 为 1（1/1）。
+
+#### 更多示例
+
+1. 计算每个部门内员工工资的累计分布：

+2. 计算每个类别内商品销售额的累计分布：
+
+```sql
+SELECT category_id,
+       product_id,
+       sales_amount,
+       CUME_DIST() OVER (PARTITION BY category_id ORDER BY sales_amount) AS cume_dist_sales

+### DENSE\_RANK 函数
+
+#### 概述
+
+`DENSE_RANK` 函数是一个窗口函数，用于计算当前行在指定分区中的连续排名，排名从1开始。当 `ORDER BY` 子句中的值相同时，`DENSE_RANK` 函数会生成相同的排名，但排名的数字不会跳跃。
+
+#### 语法
+
+```sql
+DENSE_RANK() OVER ([PARTITION_clause] [ORDER_BY_clause])
+```
+
+#### 参数说明
+
+* `PARTITION_clause` (可选)：指定分区的子句，用于将数据集划分为不同的分区。如果未指定分区，则对整个数据集应用排名。
+* `ORDER_BY_clause`：指定用于对数据进行排序的列或表达式。
+
+#### 返回类型
+
+返回值类型为 `bigint` 类型。
+
+#### 使用示例
+
+1. 基本使用
+
+```sql
+
+SELECT 
+       name,
+       salary,

+| null      | null   | 1           |
++-----------+--------+-------------+
+```
+
+在此示例中，我们根据部门ID对员工进行分区，并按工资降序排列，计算每个员工在其所在部门中的薪资排名。
+
+2. 无分区排名
+
+```sql

+| null    | null   | 8           |
++---------+--------+-------------+
+```
+
+在这个例子中，我们没有指定分区，因此将计算整个产品数据集中的库存排名，按库存数量升序排列。
+
+3. 多列排序
+
+```sql
+SELECT student_id,
+       student_name,
+       exam_score,
+       dense_rank() OVER (PARTITION BY exam_subject ORDER BY exam_score DESC, student_name ASC) AS score_rank

+
+在这个示例中，我们首先按考试科目进行分区，然后按考试成绩降序排列，如果成绩相同，则按学生姓名升序排列，计算每个学生在各科目考试中的排名。
+
+#### 注意事项
+
+* 当 `ORDER BY` 子句中的值相同时，`DENSE_RANK` 函数不会生成跳跃的排名，排名将重复。
+* 与 `RANK()` 函数相比，`DENSE_RANK()` 函数在处理相同值时具有更紧凑的排名，而 `RANK()` 函数会产生有间断的排名。
+* 在使用 `DENSE_RANK()` 函数时，请确保 `ORDER BY` 子句正确地反映了您希望对数据进行排序的方式。

+### FIRST函数
+
+```
+FIRST(expr[, ignoreNull]) OVER ([partition_clause] [orderby_clause] [frame_clause])
+```
+
+#### 功能描述
+
+排序键相同时，FIRST函数用于返回指定窗口内第一行的值。当窗口内存在非null值时，将返回第一行的非null值。如果窗口内所有值均为null，并且ignoreNull参数设置为true，则返回第一个null值。该函数为非确定性函数。
+
+#### 参数说明
+
+* **expr**: 任意类型的表达式。
+* **ignoreNull**: 可选参数，布尔类型，默认值为false。当设置为true时，如果窗口内所有值均为null，将返回第一个null值。
+
+#### 返回类型
+
+返回值类型与输入的expr类型相同。
+
+#### 使用示例
+
+**示例1：基本使用**
+
+```sql
+
+SELECT dep_no, salary, FIRST(salary,true) OVER (PARTITION BY dep_no) AS first_salary

+### LAG 函数
+
+#### 简介
+
+LAG 函数用于获取当前行的前一行或指定行数的行数据。通过使用 LAG 函数，您可以轻松地访问窗口内的前一行数据，以便进行计算或比较。
+
+#### 语法
+
+```sql
+LAG(expr[,offset[,default]]) OVER ([partition_clause] orderby_clause)
+```
+
+#### 参数说明
+
+* `expr` (任意类型): 需要获取前一行的表达式。
+* `offset` (可选，`bigint` 类型常量，默认为 1): 表示从当前行向前移动的行数。当值为 0 时，表示当前行；当值为正数时，表示向前移动的行数；当值为负数时，表示向后移动的行数。
+* `default` (可选，与 `expr` 类型相同的常量，默认为 `null`): 当 `offset` 超出窗口边界时使用的默认值。
+
+#### 返回结果
+
+返回与 `expr` 相同的数据类型。
+
+#### 使用示例
+
+1. 获取前一行的数据：
+
+```sql
+SELECT a, b, LAG(b) OVER (PARTITION BY a ORDER BY b) as prev_b FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
+```
+
+结果：
+
+```
+A	1	null
+A	1	1
+A	2	1
+B	3	null
+```
+
+2. 获取前两行的数据：
+
+```sql
+SELECT a, b, LAG(b, 2) OVER (PARTITION BY a ORDER BY b) as prev_b FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
+```
+
+结果：
+
+```
+A	1	null
+A	2	null
+A      2        1
+B	3	null
+```
+
+3. 使用默认值：
+
+```sql
+SELECT a, b, LAG(b, 1, 0) OVER (PARTITION BY a ORDER BY b) as prev_b FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
+```
+
+结果：
+
+```
+A	1	0
+A	1	1
+A	2	1
+B	3	0
+```
+
+#### 总结
+
+LAG 函数是一个非常实用的工具，可以帮助您轻松地访问窗口内的前一行数据。通过调整 offset 和 default 参数，您可以灵活地获取所需的数据。在实际应用中，LAG 函数可以用于计算移动平均、累积和等统计指标。

+   | Jeff      | 35000  | 35000      |
+   | Frank     | 30000  | 30000      |
+   | Felix     | 21000  | 21000      |
+   | Tom       | 23000  | 23000      |
+   | Charles   | 23000  | 23000      |
+   | Charles F | 23000  | 23000      |
+   | NotNull   | 23000  | 23000      |
+   | Jane      | 29000  | 29000      |
+   | Paul      | 29000  | 29000      |
+   | Alex      | 32000  | 32000      |
+   +-----------+--------+------------+
+   ```
+
+2. 忽略 NULL 值：
+
+   在这个例子中，我们将忽略工资为 NULL 的记录。
+
+   ```sql
+   SELECT name, salary, LAST(salary,true) OVER (PARTITION BY salary ) as min_salary
+    FROM VALUES
+     ('Eric', 1, 28000),
+     ('Alex', 1, 32000),
+     ('Felix', 2, 21000),
+     ('Frank', 1, 30000),
+     ('Tom', 2, 23000),
+     ('Jane', 3, 29000),
+     ('Jeff', 3, 35000),
+     ('Paul', 2, 29000),
+     ('Charles', 2, 23000),
+     ('Charles F', 2, 23000),
+     ('null',4,null),
+     ('NotNull',4,23000)
+     AS tab(name, dep_no, salary);
+   +-----------+--------+------------+
+   |   name    | salary | min_salary |
+   +-----------+--------+------------+
+   | null      | null   | null       |
+   | Eric      | 28000  | 28000      |
+   | Jeff      | 35000  | 35000      |
+   | Frank     | 30000  | 30000      |
+   | Felix     | 21000  | 21000      |
+   | Tom       | 23000  | 23000      |
+   | Charles   | 23000  | 23000      |
+   | Charles F | 23000  | 23000      |
+   | NotNull   | 23000  | 23000      |
+   | Jane      | 29000  | 29000      |
+   | Paul      | 29000  | 29000      |
+   | Alex      | 32000  | 32000      |
+   +-----------+--------+------------+
+   ```
+
+3. 结合 ORDER BY 使用：
+
+   ```sql
+   SELECT name, salary, LAST(salary) OVER (PARTITION BY dep_no ORDER BY dep_no DESC) as min_salary
+    FROM VALUES
+     ('Eric', 1, 28000),
+     ('Alex', 1, 32000),
+     ('Felix', 2, 21000),
+     ('Frank', 1, 30000),
+     ('Tom', 2, 23000),
+     ('Jane', 3, 29000),
+     ('Jeff', 3, 35000),
+     ('Paul', 2, 29000),
+     ('Charles', 2, 23000),
+     ('Charles F', 2, 23000),
+     ('null',4,null),
+     ('NotNull',4,23000)
+     AS tab(name, dep_no, salary);
+   +-----------+--------+------------+
+   |   name    | salary | min_salary |
+   +-----------+--------+------------+
+   | Jane      | 29000  | 35000      |
+   | Jeff      | 35000  | 35000      |
+   | Eric      | 28000  | 30000      |
+   | Alex      | 32000  | 30000      |
+   | Frank     | 30000  | 30000      |
+   | Felix     | 21000  | 23000      |
+   | Tom       | 23000  | 23000      |
+   | Paul      | 29000  | 23000      |
+   | Charles   | 23000  | 23000      |
+   | Charles F | 23000  | 23000      |
+   | null      | null   | 23000      |
+   | NotNull   | 23000  | 23000      |
+   +-----------+--------+------------+
+   ```
+
+4. 使用窗口函数：
+
+   当您需要对整个数据集应用 LAST 函数时，可以使用 `ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING` 子句。
+
+   ```sql
+   SELECT name, salary, LAST(salary, true) OVER (ORDER BY salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) as global_min_salary
+    FROM VALUES
+     ('Eric', 1, 28000),
+     ('Alex', 1, 32000),
+     ('Felix', 2, 21000),
+     ('Frank', 1, 30000),
+     ('Tom', 2, 23000),
+     ('Jane', 3, 29000),
+     ('Jeff', 3, 35000),
+     ('Paul', 2, 29000),
+     ('Charles', 2, 23000),
+     ('Charles F', 2, 23000),
+     ('null',4,null),
+     ('NotNull',4,23000)
+     AS tab(name, dep_no, salary);
+   +-----------+--------+-------------------+
+   |   name    | salary | global_min_salary |
+   +-----------+--------+-------------------+
+   | null      | null   | 35000             |
+   | Felix     | 21000  | 35000             |
+   | Tom       | 23000  | 35000             |
+   | Charles   | 23000  | 35000             |
+   | Charles F | 23000  | 35000             |
+   | NotNull   | 23000  | 35000             |
+   | Eric      | 28000  | 35000             |
+   | Jane      | 29000  | 35000             |
+   | Paul      | 29000  | 35000             |

+
+#### 功能描述
+排序键相同时`LAST_VALUE` 函数用于返回在指定窗口内的最后一行的某个表达式的值。该函数在数据分析和处理中非常有用，特别是当你需要获取分组内或整个数据集的最后一个非空值时。
+
+#### 参数说明
+- `expr`：任意类型的表达式，其值将被返回。
+- `ignoreNull`（可选）：布尔类型常量，默认值为 `false`。当设置为 `true` 时，函数将忽略窗口内的空值（`NULL`），并返回最后一个非空值。
+
+#### 返回结果
+返回值的类型与 `expr` 参数的类型相同。
+
+1. 基本使用：

+### LEAD 函数
+
+#### 简介
+LEAD 函数是窗口函数的一种，用于访问当前行之后指定偏移量的行。通过使用 LEAD 函数，您可以获取当前行向分区尾部方向移动指定行数后对应的表达式的值。这在数据分析和处理中非常有用，例如比较当前行与下一行的数据差异。
+
+#### 语法
+```sql
+LEAD(expr[, offset[, default]]) OVER ([PARTITION BY clause] ORDER BY clause)
+```
+
+#### 参数
+- `expr`: 任意类型的表达式，可以是列名、常量或函数等。
+- `offset`: 可选参数，bigint 类型常量，默认值为 1，表示当前行后面的一行。当 offset 为 0 时，表示当前行本身。
+- `default`: 可选参数，当 offset 超过窗口的边界时使用的缺省值。类型与 expr 相同，默认值为 null。
+
+#### 返回结果
+返回值类型与 expr 相同。
+
+#### 使用示例
+
+1. 基本使用
+```sql
+SELECT a, b, LEAD(b) OVER (PARTITION BY a ORDER BY b) as next_b FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
+```
+结果：
+```
+A	1	1
+A	1	2
+A	2	null
+B	3	null
+```
+
+2. 使用 offset 和 default 参数
+```sql
+SELECT a, b, LEAD(b, 2, 0) OVER (PARTITION BY a ORDER BY b) as next_b FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
+```
+结果：
+```
+A	1	2
+A	1	0
+A	2	0
+B	3	0
+```
+
+
+#### 注意事项
+- 当 offset 值超出窗口边界时（例如，当前行之后没有足够的行），LEAD 函数将返回 default 参数指定的值。
+- LEAD 函数通常与窗口函数的 ORDER BY 子句一起使用，以确定如何访问相关行。
+- 在使用 LEAD 函数时，请确保正确设置 PARTITION BY 子句，以便正确地对数据进行分区。

+### MAX 函数
+
+```sql
+max(expr) OVER ([partition_clause] [orderby_clause] [frame_clause])
+```
+
+#### 功能描述
+
+MAX 函数用于计算并返回指定表达式（expr）在窗口范围内的最大值。该函数常用于数据分析和统计，以便快速获取某个分组或整体数据的最大值。
+
+#### 参数说明
+
+* **expr**: 需要计算最大值的表达式，可以是数值类型、字符串类型、时间类型等可比较的类型。
+
+#### 返回结果
+
+返回值的类型与传入的表达式类型相同。
+

+## 简介
+
+NTH\_VALUE 函数用于从指定窗口内返回第 offset 行的值。该函数在处理数据时非常有用，特别是当需要获取特定位置的数据时。
+
+## 语法
+
+```sql
+nth_value(expr, offset[,ignoreNull]) over ([partition_clause] [orderby_clause] [frame_clause])
+```
+
+## 参数
+
+* `expr`: 任意类型的表达式。
+* `offset`: 大整数类型（BIGINT），必须是正整数常量。当 offset 为 1 时，函数行为与 FIRST\_VALUE 函数相同。
+* `ignoreNull`: 可选参数，布尔类型常量，默认为 false。当设置为 true 时，函数将返回窗口内第 offset 个非 null 的值。
+
+## 返回结果
+
+返回值类型与 expr 类型相同。
+
+## 使用示例
+
+```sql
+SELECT dep_no, salary, nth_value(salary, 3) OVER (PARTITION BY dep_no)

+### 百分比排名函数（PERCENT\_RANK）
+
+#### 概述
+
+`PERCENT_RANK` 函数用于计算指定行在其所在分区中的百分比排名。该函数会根据 `ORDER BY` 子句指定的排序顺序对数据进行排序，并计算每个分区中各行的排名。其返回值是一个 `double` 类型，值域在 [0.0, 1.0] 范围内。具体计算公式为 `(当前行排名 - 1) / (分区总行数 - 1)`。当分区中只有一行时，返回值为 0。
+
+#### 使用方法
+
+```sql
+PERCENT_RANK() OVER (
+    [PARTITION BY partition_expression, ...]
+    [ORDER BY sort_expression [ASC | DESC], ...]
+)
+```
+
+* `PARTITION BY` 子句（可选）：指定用于分区的表达式，可以有多个。如果省略此子句，将使用整个结果集作为一个分区。
+* `ORDER BY` 子句：指定用于排序的表达式，可以有多个，并可指定排序方向（升序 ASC 或降序 DESC）。
+
+#### 示例
+
+以下示例展示了如何使用 `PERCENT_RANK` 函数计算不同部门人员的薪水排名百分比。
+

+### RANK 函数
+
+#### 概述
+
+`RANK()` 函数用于计算当前行在指定分区中的排名。排名从 1 开始，根据 `ORDER BY` 子句中的值进行排序。若存在相同的排序值，`RANK()` 函数会将相同的排名分配给这些行，并将下一个排名跳过。
+
+#### 语法
+
+```sql
+RANK() OVER ([PARTITION BY column_name | column_name, ...] [ORDER BY column_name [ASC|DESC], ...])
+```
+
+#### 参数说明
+
+* `PARTITION BY`：可选参数，用于将数据分区。可以指定一个或多个列名，对数据进行分区。
+* `ORDER BY`可选参数，用于指定排序的列和排序方式（升序或降序）。
+
+#### 返回值
+
+* 返回值类型为 bigint 类型。
+* 返回值可能不连续，可能重复。若存在相同的 `ORDER BY` 值，结果相同，为第一个 `ORDER BY` 行的排名。
+
+#### 示例
+
+1. 基本使用
+   我们可以使用 `RANK()` 函数来计算每个员工的薪水排名。
+   ```sql
+   SELECT name, salary, RANK() OVER (ORDER BY salary DESC) AS rank 
+    FROM VALUES
+     ('Eric', 1, 28000),
+     ('Alex', 1, 32000),
+     ('Felix', 2, 21000),
+     ('Frank', 1, 30000),
+     ('Tom', 2, 23000),
+     ('Jane', 3, 29000),
+     ('Jeff', 3, 35000),
+     ('Paul', 2, 29000),
+     ('Charles', 2, 23000),
+     ('Charles F', 2, 23000),
+     ('null',4,null),
+     ('NotNull',4,23000)
+     AS tab(name, dep_no, salary);
+   +-----------+--------+------+
+   |   name    | salary | rank |
+   +-----------+--------+------+
+   | Jeff      | 35000  | 1    |
+   | Alex      | 32000  | 2    |
+   | Frank     | 30000  | 3    |
+   | Jane      | 29000  | 4    |
+   | Paul      | 29000  | 4    |
+   | Eric      | 28000  | 6    |
+   | Tom       | 23000  | 7    |
+   | Charles   | 23000  | 7    |
+   | Charles F | 23000  | 7    |
+   | NotNull   | 23000  | 7    |
+   | Felix     | 21000  | 11   |
+   | null      | null   | 12   |
+   +-----------+--------+------+
+   ```
+
+2. 分区使用
+   如果我们想要根据员工的部分（grade）来计算薪水排名，可以使用 `PARTITION BY` 子句。
+
+```SQL
+ SELECT name,dep_no, salary, RANK() OVER (PARTITION BY dep_no ORDER BY salary DESC) AS rank 
+    FROM VALUES
+     ('Eric', 1, 28000),
+     ('Alex', 1, 32000),
+     ('Felix', 2, 21000),
+     ('Frank', 1, 30000),
+     ('Tom', 2, 23000),
+     ('Jane', 3, 29000),
+     ('Jeff', 3, 35000),
+     ('Paul', 2, 29000),
+     ('Charles', 2, 23000),
+     ('Charles F', 2, 23000),
+     ('null',4,null),
+     ('NotNull',4,23000)
+     AS tab(name, dep_no, salary);
+   +-----------+--------+--------+------+
+   |   name    | dep_no | salary | rank |
+   +-----------+--------+--------+------+
+   | Jeff      | 3      | 35000  | 1    |
+   | Jane      | 3      | 29000  | 2    |
+   | Alex      | 1      | 32000  | 1    |
+   | Frank     | 1      | 30000  | 2    |
+   | Eric      | 1      | 28000  | 3    |
+   | Paul      | 2      | 29000  | 1    |
+   | Tom       | 2      | 23000  | 2    |
+   | Charles   | 2      | 23000  | 2    |
+   | Charles F | 2      | 23000  | 2    |
+   | Felix     | 2      | 21000  | 5    |
+   | NotNull   | 4      | 23000  | 1    |
+   | null      | 4      | null   | 2    |
+   +-----------+--------+--------+------+
+```
+
+3. 多列排序
+   如果我们需要根据两个或更多列进行排序，可以在 `ORDER BY` 子句中指定这些列。
+   ```sql
+   SELECT name,dep_no, salary, RANK() OVER (PARTITION BY dep_no ORDER BY salary DESC,name ASC) AS rank 
+    FROM VALUES
+     ('Eric', 1, 28000),
+     ('Alex', 1, 32000),
+     ('Felix', 2, 21000),
+     ('Frank', 1, 30000),
+     ('Tom', 2, 23000),
+     ('Jane', 3, 29000),
+     ('Jeff', 3, 35000),
+     ('Paul', 2, 29000),
+     ('Charles', 2, 23000),
+     ('Charles F', 2, 23000),
+     ('null',4,null),
+     ('NotNull',4,23000)
+     AS tab(name, dep_no, salary);
+   +-----------+--------+--------+------+
+   |   name    | dep_no | salary | rank |
+   +-----------+--------+--------+------+
+   | Jeff      | 3      | 35000  | 1    |
+   | Jane      | 3      | 29000  | 2    |
+   | Alex      | 1      | 32000  | 1    |
+   | Frank     | 1      | 30000  | 2    |
+   | Eric      | 1      | 28000  | 3    |
+   | Paul      | 2      | 29000  | 1    |
+   | Charles   | 2      | 23000  | 2    |
+   | Charles F | 2      | 23000  | 3    |
+   | Tom       | 2      | 23000  | 4    |
+   | Felix     | 2      | 21000  | 5    |
+   | NotNull   | 4      | 23000  | 1    |
+   | null      | 4      | null   | 2    |
+   +-----------+--------+--------+------+
+   ```
+
+#### 注意事项
+
+* `RANK()` 函数可能在存在相同排序值的情况下产生不连续的排名。
+* 使用 `RANK()` 函数时，确保 `ORDER BY` 子句中的列与您希望根据其排名的列相匹配。

+   | null      | 4      | null   | 2       |
+   +-----------+--------+--------+---------+
+   ```
+
+#### 注意事项
+
+* `ROW_NUMBER()` 函数对于每个分区都是独立的，即每个分区都会有自己的行号序列。
+* 使用 `ROW_NUMBER()` 函数时，应确保 `ORDER BY` 子句中的排序键是唯一的，以避免产生非连续的行号。
+* 当 `ORDER BY` 子句中的排序键存在相同值时，默认情况下 `ROW_NUMBER()` 函数会产生非连续的行号。如果需要连续的行号，可以考虑使用 `DENSE_RANK()` 函数。

+### 窗口函数概述
+
+窗口函数是 SQL 中一种强大的分析工具，它允许您在一组相关行上执行计算，而不仅仅是针对单个行。窗口函数通过创建一个“窗口”来查看当前行及其上下文行，从而实现复杂的数据分析任务。
+
+#### 语法
+
+```sql
+function_name([expr [, ...]]) OVER ( [window_definition] )
+```
+
+* `function_name`: 内置的窗口函数，如 `SUM`、`COUNT` 等。
+* `expr`: 函数参数，根据实际数据确定。
+* `window_definition`: 窗口定义，用于指定如何在数据集上应用窗口函数。
+
+#### 窗口定义
+
+```sql
+[PARTITION BY expression [, ...]]
+[ORDER BY expression [ASC|DESC]] [, ...]
+[FRAME frame_clause]
+```
+
+* `PARTITION BY` 子句: 可选，用于将数据集划分为不同的分区。
+* `ORDER BY` 子句: 可选，用于指定数据在每个窗口内的排序方式。建议使用唯一的列或列组合来减少随机性。
+* `FRAME` 子句: 可选，用于确定窗口的边界。具体描述如下。
+
+#### FRAME 子句
+
+```sql
+{ROWS|RANGE} BETWEEN frame_start AND frame_end
+```
+
+`FRAME` 子句定义了一个闭区间，用于确定数据边界。`ROWS` 和 `RANGE` 是两种类型的边界类型。
+
+* `ROWS` 类型: 通过数据行号确定边界。
+* `RANGE` 类型: 当指定了 `ORDER BY` 时，使用列值的大小关系来确定边界。未指定 `ORDER BY` 时，所有行被认为具有相同的值。
+
+`frame_start` 和 `frame_end` 表示窗口的起始和终止边界。`frame_start` 是必填的，`frame_end` 可选，默认值为 `CURRENT ROW`。具体选项如下：
+
+- `UNBOUNDED PRECEDING`: 表示分区或结果集的开始。
+- `OFFSET PRECEDING`: 表示相对于当前行的偏移量。
+- `CURRENT ROW`: 仅表示当前行。
+- `OFFSET FOLLOWING`: 表示相对于当前行之后的偏移量。
+- `UNBOUNDED FOLLOWING`: 表示分区或结果集的结束。
+
+在没有显式设置 `FRAME` 子句时，默认的 `FRAME` 子句为：
+
+```sql
+RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
+```
+
+#### 使用示例
+
+```sql
+SELECT
+  name,
+  dep_no,
+  salary,
+  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) rows_up_uf,
+  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) range_up_uf,
+  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) rows_up_cr,
+  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) range_up_cr,
+  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary ROWS BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING) rows_cr_uf,
+  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary RANGE BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING) range_cr_uf,
+  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING) rows_1p_1f
+FROM VALUES
+  ('Eric', 1, 28000),
+  ('Alex', 1, 32000),
+  ('Felix', 2, 21000),
+  ('Frank', 1, 30000),
+  ('Lily', 2, 23000),
+  ('Jane', 3, 29000),
+  ('Jeff', 3, 35000),
+  ('Paul', 2, 29000),
+  ('Charles', 2, 23000)
+  AS tab(name, dep_no, salary);
+```
+
+#### 窗口函数分类
+
+窗口函数根据其行为可以分为以下三类：
+
+1. 排名函数（ranking_function）：用于计算排名，必须指定 `ORDER BY`，不能指定 `FRAME` 子句。例如：
+   - `ROW_NUMBER`
+   - `RANK`
+   - `DENSE_RANK`
+   - `PERCENT_RANK`
+   - `NTILE`
+2. 分析函数（analytic_function）：用于执行更复杂的分析计算。例如：
+   - `CUME_DIST`
+   - `

+# 使用SQL对客户进行RFM分析
+# # **什么是 RFM 分析？**
+**RFM 报告**是一种使用三个关键指标对客户进行细分的方法：新近度（他们上次购买是在多长时间前）、频率（他们购买的频率）和货币价值（他们花了多少钱）。
+
+**RFM 分析**基于这样的假设，即最近从您那里购买过的客户更有可能再次购买这一原则适用于各种行业，有证据表明，与不经常购买或消费较少的客户相比，频繁购买者和大手笔消费者更有可能对促销活动做出反应。
+
+**RFM**创建于上世纪 90 年代，旨在提高直邮营销活动的效率，它利用[**帕累托原理**](https://mode.com/blog/pareto-chart-101/)来回答关键问题，例如：
+
+* 谁是我最好或最忠诚的客户？
+* 我有失去哪些客户的危险？
+* 我应该将营销工作重点放在哪些客户身上？
+* 我可以吸引哪些客户花更多钱？
+
+**这种客户分析会对您的业务产生巨大影响** 无论您是想提高营销 ROI、建立忠诚度、减少客户流失还是增加CLV，RFM 分析都是朝着正确方向迈出的一步。
+
+一旦您有了包含每个客户的新近度（R）、频率（F）和货币价值（M）数据的表格，就可以开始细分了。虽然您可以根据需要对数据进行精细分割，但使用五分位数反映了帕累托原则，它表明您的哪些客户在所有三个指标中都处于前 20%。
+要创建五分位数，我们将使用一个ntile窗口函数，它只需要在原始RFM 值查询的顶部添加几行额外的 SQL 。
+##  **如何为数据创建 RFM 报告**
+
+因为它只关注三个指标，RFM 报告看似简单。例如，在对 数据 进行 RFM 分析时，您真正需要的只是三个数据点：
+
+* **新近度（R，recency）**- 最后订购日期
+* **频率（F，frequency）**- 订单总数
+* **货币价值（M，monetary）**- 总支出
+
+**这些指标共同揭示了您的回头客是谁，哪些客户随着时间的推移最忠诚，以及哪些客户在您的商店中花费最多**。 RFM 报告提供有关您的客户的重要信息，虽然 RFM 与 B2C 和零售密切相关，但对于 B2B、服务或 SaaS 企业来说，它是更好地了解其客户的同样有效的方式。
+
+## 数据说明
+本文所使用的数据来自云器Lakehouse的共享样例数据，可以直接按照如下方式直接使用:
+```
+select * from clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore limit 10;
+```
+![](.topwrite/assets/image_1718761578596.png)
+
+## 创建RFM需要的值
+```
+DROP TABLE if exists eCommerce_RFM_Values;
+
+CREATE TABLE eCommerce_RFM_Values
+
+AS
+
+SELECT user_id,
+
+MIN(event_date) AS first_order_date,
+
+MAX(event_date) AS last_order_date,
+
+COUNT(1) AS count_order,
+
+sum(price) AS sum_amount
+
+FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore
+
+WHERE event_type = 'purchase'
+
+GROUP BY user_id
+
+ORDER BY user_id;
+```
+## 创建RFM Quintiles
+本文为了简单演示，用了两分位（ntile(2)，而不是ntile(5)）。此查询返回一个表，其中包含客户电子邮件以及每个客户在新近度、频率和货币价值方面所属的二分位数。从新近度来看，2 表示客户的购买在最近的前 50% 内，而 1 表示客户在后 50% 内。
+```
+DROP TABLE if exists eCommerce_RFM_Quintiles;
+
+CREATE TABLE eCommerce_RFM_Quintiles
+
+AS
+
+SELECT user_id,
+
+ntile(2) OVER (ORDER BY last_order_date) AS rfm_recency,
+
+ntile(2) OVER (ORDER BY count_order) AS rfm_frequency,
+
+ntile(2) OVER (ORDER BY sum_amount) AS rfm_monetary,
+
+first_order_date,
+
+last_order_date,
+
+count_order,
+
+sum_amount
+
+FROM eCommerce_RFM_Values
+
+ORDER BY user_id;
+```
+## 创建 RFM 单元
+现在您知道了您的客户通常属于哪里，让我们使五分位数数据更易于使用。最常见的方法是将每个指标的五分位等级连接起来，以创建一个3 位数，也称为“单元格”。
+以这种方式连接数据时，最佳客户的单元格值为 222（五分位则为555），因为他们在所有三个指标中都处于前 50%，而在所有三个指标中处于后 50% 的客户的单元格值为 111 .
+```
+DROP TABLE if exists eCommerce_RFM_Cell;
+CREATE TABLE eCommerce_RFM_Cell
+
+AS
+
+SELECT user_id,
+
+rfm_recency,
+
+rfm_frequency,
+
+rfm_monetary,
+
+rfm_recency || rfm_frequency || rfm_monetary AS rfm_cell,
+
+first_order_date,
+
+last_order_date,
+
+count_order,
+
+sum_amount
+
+FROM eCommerce_RFM_Quintiles
+
+ORDER BY user_id;
+```
+## 创建可操作的 RFM Segment
+
+现在您已经有了清晰的 RFM 单元，您需要创建有意义的分组，以帮助将数据转化为可操作的见解。通过三个指标和每个指标的五个层级，您可以创建多达 125 (5x5x5) 个客户群。如果 125 段的想法让您头疼，请考虑使用四分位数（这会给您 4x4x4 = 64 个段）甚至三分之一（3x3x3 = 27 个段）来简化事情。
+
+如何划分细分市场取决于您的业务性质。如果您是 Pareto 的铁杆粉丝，想要奖励您的最佳购买者，您可能希望关注 RFM 单元格为 555 的客户。但是，如果您想要稍微开放一些，以包括最近和常客，他们可能有花费少一点，您可以创建一个细分，其中包含 RFM 单元格值为 555 和 554 的每个人。
+
+创建客户细分时的关键是使存储桶足够大以便于采取行动——如果营销人员认为他们需要创建 125 个单独的客户营销活动，他们就会失去理智——但又要小到你可以将它们作为一个整体来处理。
+
+创建客户细分时的关键是使存储桶足够大以便于操作，但又要足够小以便您可以将它们作为一个组来处理。

+# 单点登录 （Private Preview）
+
+本文档旨在帮助您逐步完成单点登录配置，确保能顺利使用 OAuth 2.0/OIDC 或 SAML 2.0 协议启用 SSO 功能。
+
+***
+
+## 基础概念简介
+
+* **单点登录**（**SSO**）：用户通过一次身份验证即可访问多个系统，简化登录流程并提高安全性。
+
+* **联合身份验证（Federated Authentication）**：Lakehouse（服务提供方，SP）信任外部身份提供方（IdP）执行用户认证。
+
+* **协议简述**：
+
+  * **SAML 2.0**：基于 XML 的身份断言协议，通过 Assertion 传递用户身份信息。
+  * **OAuth 2.0 / OpenID Connect（OIDC）**：OAuth 提供授权机制，OIDC 增加身份层，使用 JWT 格式的 ID Token 表达用户身份。
+
+## ClickZetta 与客户 IdP 的关系
+
+* 在 IdP 中注册 Lakehouse 应用（提供回调地址/ACS、Entity ID、签名或加密证书）
+* 在 Lakehouse 平台中填写 IdP 提供的参数
+* 配置完成后支持两种登录流程：用户从 Lakehouse 登录（SP-init）或从 IdP 登录（如果支持 IdP-init）
+
+## 功能局限
+
+当前 Lakehouse **不支持**以下功能，请在配置与使用时注意：
+
+1. **不支持全局登出**。用户在 IdP 的登出操作不影响在 Lakehouse 的登录状态。用户需要在 Lakehouse 中单独登出。
+2. **不支持配置多个 IdP**。仅支持一个 IdP 连接。
+3. **单点登录仅支持 Web 端登录**。当前不支持通过 JDBC、Python SDK、Java SDK 等使用 SSO 登录。
+4. **身份映射字段局限**：SAML 2.0 协议仅支持使用 Email 作为用户身份映射字段；OAuth 2.0 / OpenID Connect (OIDC) 协议仅支持使用 Email 或 Phone 作为用户身份映射字段。
+5. **身份映射字段唯一性要求**：当某字段被用作身份映射字段时，在 Lakehouse 中所有用户的该字段信息须保持唯一。如果 Lakehouse 中多个用户的邮箱或手机号信息存在重复，且该字段被用于单点登录的身份映射字段，则信息重复的用户将不能正常登录。
+
+***
+
+## 协议配置指南
+
+### 开启单点登录
+
+Lakehouse账户中，SSO登录（单点登录）默认关闭。拥有账户管理员身份的用户可以操作开启。
+
+登录 Lakehouse 账户，进入“账户中心”页面，在 SSO 登录选项中，点击“开启 SSO 登录”。
+
+![](.topwrite/assets/screenshot-20250814-145644.png)
+
+**注意**：开启 SSO 登录后，该账户下所有用户只能使用 SSO 方式登录，不再允许使用用户名/密码方式进行 Web 登录。因此在开启单点登录前，请确保账户下所有需要登录 Lakehouse 的用户：
+
+1）在Idp中拥有用户身份；
+
+2）在Lakehouse中用于身份映射的信息（邮箱或电话号码）唯一，不与其他用户重复。
+
+### OAuth 2.0 / OpenID Connect (OIDC) 协议
+
+**1. 选择协议**
+
+开启 SSO 登录后，在右侧弹窗中选择 “OAuth 2.0 / OIDC 协议”。选择协议后，您可在协议下方看到该协议的回调地址，如：
+
+:-: ![](.topwrite/assets/image_1755158785697.png =575)
+
+```SQL
+https://api.clickzetta.com/clickzetta-portal/sso/oidc/consume?u={code}
+```
+
+^
+
+请使用该回调地址，在您的 IdP 服务中注册 Lakehouse 应用，并记录注册后的 Client ID 和其他配置值，以便在后续配置中使用。
+
+**配置授权端点（Authorization Endpoint）**
+
+:-: ![](.topwrite/assets/image_1755160968700.png =525)
+
+**参数**：
+
+* 授权端点URL（例如 `https://idp.example.com/authorize`）：用于重定向用户到 IdP 进行身份授权
+* Client ID：标识 Lakehouse 在 IdP 上的应用，您可在您的 IdP 服务中完成对 Lakehouse 应用的注册后获得。
+* 响应类型（response\_type）：仅支持Code模式。
+* Scope（如 `openid`, `profile`, `email`）：决定可以请求的用户信息，支持多选。当使用 OpenID Connect 协议时，必须勾选 openid 选项。支持勾选“其他”后填写自定义的 scope 参数。
+* 可选扩展参数：便于根据 IdP 要求添加额外字段（如 `prompt=login`）。
+
+**配置令牌端点（Token Endpoint）**
+
+:-: ![](.topwrite/assets/image_1755161141507.png =510)
+
+**参数**：
+
+* 令牌端点URL：用于交换授权码获取令牌。通常在Lakehouse调用Idp的授权端点后，会获取访问Code。Lakehouse 会继续调用令牌端点 URL 来使用 Code 交换令牌。
+* Client Secret（非必须）：用于验证客户端身份。如 IdP 系统注册应用未颁发则此项可为空。
+* 可选扩展参数：根据 IdP 要求添加。
+
+^
+
+**配置用户信息端点（UserInfo Endpoint）**
+
+:-: ![](.topwrite/assets/image_1755161329682.png =530)
+
+**参数**：
+
+* 用户信息端点URL：用于Lakehouse调用并获取用户详细信息。
+* 身份映射配置：
+* userinfo 字段：指 Lakehouse 从 UserInfo Endpoint 获取的身份信息字段。可选 Email、Phone 或自定义字段。
+* 身份映射字段：指能够与 UserInfo 指定字段匹配的身份信息字段，可选 Email 或 Phone。注意：如果身份映射字段选择 Phone（手机号），Lakehouse 能够识别国家码为 00、+ 或不填写国家码的三种手机号格式。
+* 测试用户信息完整度：根据所选的“身份映射字段”，检查并列出当前账户下所有用户中缺失该信息或该信息重复的用户。这些用户在开启SSO后，不能正常登录。
+* 可选扩展参数：根据 IdP 要求添加。
+
+**账户管理员可同时使用云器账号登录**
+
+开启该选项，则允许具备账户管理员角色的用户继续使用用户名和密码登录，以便当SSO登录出现故障时，仍能够登录并修改账户配置。
+
+^
+
+### SAML 2.0 协议
+
+**选择协议**
+
+开启 SSO 登录后，在右侧弹窗中选择 “SAML 2.0 协议”。选择协议后，您可在协议下方看到该协议的回调地址（Assertion Consumer Service URL），如：
+
+:-: ![](.topwrite/assets/image_1755161484299.png =616)
+
+```SQL
+https://api.clickzetta.com/clickzetta-portal/sso/saml/consume?u={code}
+```
+
+请使用该地址，在 IdP 中注册应用，并记录及保存 IdP 所返回的 Entity ID 和 X.509 证书。
+
+^
+
+**填写 SSO 登录 URL**
+
+:-: ![](.topwrite/assets/image_1755161389065.png =457)
+
+**参数**：
+
+* SSO Login URL：IdP 接收 SAML Request 的端点。
+* Entity ID：IdP 中对应用的身份标识，在 IdP 内完成应用注册后可以获得。
+* X.509 证书（非必须）：用于校验签名、保证数据安全，在 IdP 内完成应用注册后可以获得。
+* Issuer（非必须）：发出 SAML 断言的实体，用于进行信任验证。
+* 测试用户信息完整度：SAML2.0协议目前仅支持以邮箱地址作为用户身份映射字段。用户信息完整度测试会检查并列出当前账户内所有用户中缺失邮箱信息或邮箱信息重复的用户。这些用户在开启SSO后，不能正常登录。
+
+**账户管理员可同时使用云器账号登录**
+
+开启该选项，则允许具备账户管理员角色的用户继续使用用户名和密码登录，以便当SSO登录出现故障时，仍能够登录并修改账户配置。
+
+***
+
+## 常见问题
+
+**问：为什么在 IdP 登录后，跳转回 Lakehouse 提示“认证失败”？**
+
+**答：**通常是映射字段（Email 或 Phone）在用户间不唯一，或未正确返回/格式有误。如果是映射字段在用户间不唯一，在认证失败的提示中会有明确提示。如未提示映射字段不唯一，则请账户管理员检查身份映射字段的配置是否正确，比如是否回传 Email 但映射为 Phone。
+
+**问：为何勾选了“账户管理员可同时使用云器账号登录”但仍不可使用用户名、密码登录？**
+
+**答：**在开启 SSO 登录且勾选“账户管理员可同时使用云器账号登录”后，仅具备账户管理员角色的用户可以使用用户名、密码登录，其他用户只能使用 SSO 方式登录。
+
+**问：是否可以通过 SDK（如 Python、JDBC）使用 SSO 登录？**
+
+**答：**当前仅支持 Web 登录。Python、JDBC 等方式当前仅支持用户名密码认证方式。

+# 数据存储加密
+
+## 概述
+
+Lakehouse 支持对存储在对象存储中的表数据进行服务端加密（Server-Side Encryption），采用 AES-256 加密算法，确保您的数据在存储层面得到安全保护。
+
+您可以根据安全合规需求，选择使用云厂商提供的托管密钥，或使用您自有的 KMS 密钥进行加密。
+
+## 加密模式
+
+Lakehouse 提供两种加密模式：
+
+| 模式         | 说明                                             |
+| ---------- | ---------------------------------------------- |
+| 托管加密（推荐）   | 使用云厂商对象存储服务提供的托管密钥进行加密，无需额外配置                  |
+| 自定义 KMS 加密 | 使用您自有的 KMS 密钥进行加密，需提供 KMS ARN（ID） 和 KMS Region |
+
+> 自定义 KMS 加密目前支持阿里云和 AWS 平台。腾讯云平台仅支持托管加密模式。
+
+## 加密范围
+
+* 您可以在工作空间级别统一开启加密，开启后该工作空间内新建的数据对象将默认加密存储。
+* 可以在任意时刻对工作空间设置开启加密，开启后不会影响工作空间中已有的表，只会对新建表应用加密。
+
+> ⚠️ 表一旦加密，无法恢复为非加密状态，请在开启前确认。
+
+## 使用方式
+
+### 在创建工作空间时开启加密
+
+1. 在创建工作空间页面，开启「存储加密」开关。
+
+2. 如果您希望使用托管加密，KMS ARN 留空即可。
+
+3. 如果您希望使用自定义 KMS 密钥：
+
+   * 填写您的 KMS 密钥 ARN。
+   * 填写 KMS Region。
+
+### 在修改工作空间时调整加密设置
+
+* 如果工作空间未使用自定义 KMS 密钥，您可以自由开启或关闭加密开关。
+* 如果工作空间已使用自定义 KMS 密钥，加密设置将被锁定，无法关闭加密或修改密钥配置。
+
+## 密钥管理
+
+* 每个数据对象在其生命周期内只能使用一个密钥，密钥不可变更。
+* 您可以创建多个密钥，在加密不同工作空间的数据对象时选用不同的密钥。
+* 使用自定义 KMS 密钥后，KMS ARN 和 KMS Region 将变为只读，不可修改。
+
+> ⚠️ 使用自定义 KMS 密钥加密后，密钥配置不可修改，加密不可关闭。请在配置前仔细确认密钥信息。
+
+> ⚠️ 请妥善保管您的自定义 KMS 加密密钥。一旦密钥遗失，Lakehouse 中使用该密钥加密的数据将永久不可读取，且无法恢复。
+
+## KMS 请求费用与缓存机制
+
+由于数仓场景下会频繁读写数据，使用自定义 KMS 密钥容易达到云厂商 KMS 服务的 QPS 请求上限，并产生大量的 KMS API 请求费用。为此，Lakehouse 采用了密钥缓存机制来减少对 KMS 的 API 调用，缓存有效期为 **5 分钟**。这意味着当 KMS 密钥被撤销或失效后，最多仍有 5 分钟的窗口期可以对加密数据进行读写。
+
+> ⚠️  建议**优先选择托管加密模式**，避免使用自定义 KMS 密钥，以免达到 KMS 请求上限影响读写性能，或产生大量的 KMS 请求费用。KMS 请求费用通常产生在您的 KMS 密钥所在的云账户中，而非 Lakehouse 账单内。
+
+## 常见问题
+
+**Q：开启工作空间加密后，历史数据会被加密吗**？
+
+不会。开启加密仅对之后新建的数据对象生效，已有数据不受影响。
+
+**Q：可以对已加密的表取消加密吗**？
+
+不可以。表的加密操作不可逆。
+
+**Q：自定义 KMS 密钥配置后可以修改吗**？
+
+不可以。一旦配置了自定义 KMS 密钥，密钥信息和加密开关均不可修改。
+
+**Q：自定义 KMS 密钥丢失了怎么办**？
+
+请务必妥善保管您的自定义 KMS 加密密钥。一旦密钥遗失，Lakehouse 中使用该密钥加密的数据将永久不可读取，且无法恢复。
+
+**Q：使用自定义 KMS 加密会产生额外费用吗**？
+
+会。每次数据读写都需要调用 KMS API 进行加解密，虽然 Lakehouse 通过 5 分钟的密钥缓存机制减少了请求次数，但在高频读写场景下仍可能产生可观的 KMS 请求费用。该费用产生在您的 KMS 密钥所在的云账户中。建议优先使用托管加密模式以避免此类费用。

+## 增量计算概述
+
+流式数据处理（Streaming data pipeline）是面向实时数据持续不断地进行数据采集、处理转换，以获得满足业务时效性要求的结果数据的一组任务集合。流式数据处理是分析人员、业务应用开展实时洞察或实时决策的基础。
+
+与周期性离线处理（Batch data pipeline）有所不同，流式数据处理通过编排实时数据采集任务和支持增量数据处理的 SQL 任务，持续产出实时更新的结果数据。处理过程中使用增量处理技术以提高处理效率，同时降低成本。
+
+云器 Lakehouse 流式数据处理过程中，总体处理流程示例如下：
+
+![](.topwrite/assets/image_1709520998068.png)
+
+流式数据处理的产品功能特性包括：
+
+| 功能特性   | 特性说明                                                                                                                                                                                                                 |
+| ------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| 实时数据加载 | **实时数据加载服务**：通过 SDK/Connector 方式提供 Streaming API，支持实时追加/更新写入、秒级可见的系统托管服务。可使用 SDK 或 Flink Connector 调用接口向目标表写入数据。**Studio 数据集成服务**：内建的数据集成工具，支持多种实时数据源（如 Kafka、数据库 CDC 等）的实时抽取，写入 Lakehouse 时通过 Streaming API 实时写入目标表。    |
+| 增量数据处理 | **动态表**：通过动态表声明式定义数据加工逻辑，支持任意 SQL 语法和算子，系统自动读取 Base 表的增量变化，自适应地通过增量/全量算法优化数据处理效率。用户可创建 1 个或多个动态表并设置调度策略，系统自动识别依赖关系并持续调度执行，大大简化实时数据处理的开发过程。注：当前最小支持 1min 的调度间隔。                                                         |
+| 变化数据捕获 | **Table Stream**：Table Stream 是系统内置的 SQL 对象类型，一个 Table Stream 创建在指定的一张表之上，可以记录该表的数据变化（CDC）信息。Table Stream 支持通过 SQL 查询获取指定两个数据版本之间的变化记录数据，例如 5 分钟前至当前这段时间的变化记录。通过 Table Stream，下游的 SQL ETL 可以非常简单易用地读取和处理表变化数据，或者将变化结果同步输出给外部系统。 |
+| 连续性调度  | 系统提供两种调度方式：
+**动态表自身设置调度周期**：通过物化视图 DDL 定义时，可通过指定 INTERVAL 关键字设置调度周期。
+**使用 Studio 调度任务调度**：在 Web IDE 中创建 SQL 任务，设置任务调度周期。此种方式同时支持对动态表、使用 Table Stream 的 SQL ETL 作业这两种任务进行调度。注：使用 Studio 调度系统，可获得更好的任务执行观测性和运维告警能力。

+# 开发动态表实现近实时增量处理
+
+> **【预览发布】** 本功能当前处于受邀预览阶段。如需试用，请通过官网联系方式联系云器科技。
+
+## 教程概述
+
+通过本教程，您将了解到如何使用Lakehouse动态表(Dynamic Table)构建一个完整的实时数据ETL加工流程。场景设计如下： 
+
+![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tutorial_dt_scenario.jpg?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=2034679003\&Signature=gewhAp%2FJ80Uu%2BFq1sNEH3fwQI54%3D)
+
+ 本教程将通过数据导入任务、基于动态表实现的数据清洗转换和数据聚合任务，实现了一个分钟级延迟的流式数据处理Pipeline案例。
+
+> 本教程借助 Lakehouse Tutorial，提供了在线教程指南以及脚本导入功能。您可以在登录 Lakehouse Web 控制台后，通过 Lakehouse Tutorial 的“Lakehouse教程”入口进入，并根据在线指南引导完成教程。
+> ![](<.topwrite/assets/截屏2025-01-14 19.36.29.png>)
+
+### 入门知识
+
+动态表（Dynamic Table）是一种支持仅处理增量变化数据的对象类型，与物化视图类似。创建动态表时，您需要同时定义数据计算逻辑。通过刷新操作，可以触发动态表的计算逻辑并更新其数据。与传统的 ETL 任务相比，动态表只需要在定义时声明全量语义的计算逻辑，在刷新时则可自动进行增量计算优化。借助动态表，Lakehouse可以面向流式写入的数据进行近实时增量处理，为实时分析提供数据准备。
+
+### 教程步骤
+
+1. **数据导入**：创建原始表、持续写入用户行为数据；
+2. **开发动态表模型**：通过 Dynamic Table 分别构造数据清洗、数据聚合的加工流程。
+3. **验证加工结果**：监控由动态表构造的数据Pipeline的刷新执行状态，同时查看消费层数据表的变化情况，验证实时数据加工结果
+
+通过以上步骤，您将了解如何通过动态表在 Lakehouse 中开发流式处理任务。
+
+## 准备工作
+
+首先，创建行为日志表，通过INSERT INTO任务写入测试数据。
+
+> 为了简化教程，本教程通过周期性调度 INSERT INTO 任务模拟数据的持续写入。实际生产环境中往往使用流式写入接口实时接入数据，云器 Lakehouse 也提供 SDK/Flink Connector 等方式进行实时写入，不建议在生产任务中使用 INSERT INTO 方式写入。
+
+本教程在“开发”模块提供了创建数据表以及插入测试数据的 SQL 脚本。打开 [Tutorial_Working_With_Dynamic_Table->Step01.Preparation] 脚本文件，配置 1Min 间隔的调度策略并提交部署，以模拟实时数据导入。

+
+## Transform Layer动态表模型开发
+
+在“开发”模块打开 [Tutorial_Working_With_Dynamic_Table->Step02.Transformation_With_Dynamic_Table] 样例动态表任务文件。该动态表定义了对原始表进行清洗转换的 ETL 逻辑。
+
+请参考下图进行调度配置"运行集群"和"调度参数"：

+# VOLUME中的结构化、半结构化数据分析
+
+### 语法：
+
+```
+SELECT { <column_name>,... | * } 
+FROM [ VOLUME <volume_name> | TABLE VOLUME <table_name> | USER VOLUME ]
+    [ ( <column_name> <column_type>, <column_name> <column_type> ... ) ]
+USING CSV|PARQUET|ORC|JSON|BSON
+OPTIONS(
+  FileFormatParams
+) 
+FILES|SUBDIRECTORY|REGEXP <pattern>;
+```
+
+### 参数说明：
+
+`<column_name> <column_type> `：可选，lakehouse支持自动识别文件内的表结构信息。推荐不用填写，当指定文件中包含的列名和文件中类型需与文件中预定义的列类型相匹配，
+
+* 自动识别文件schema对于csv文件则会则会自动生成字段，字段编号以 f0 开始,目前自动识别的类型为int、double、string、bool
+* 对于 parquet、orc 格式将会根据文件中存储的字段名和类型自动识别。如果指定的文件中列的个数不一致。Lakehouse 会尝试合并，无法合并则会报错
+
+`USING CSV`：
+
+* `sep`：列分隔符，默认为 `”,“`。最多支持长度为 1 的字符，例如：`'sep'=','`
+* `compression`：配置文件压缩格式。支持的压缩格式有：`gzip/zstd/zlib`。例如：`'compression'='gzip'`
+* `lineSep`：行分隔符，默认值为`"\n"`。最多支持长度为 2 的字符，例如：`'lineSep'='$'`
+* `quote`：设置用于转义引号值的单个字符。默认值为双引号`“"“`，例如：`'quote'='"'`
+* `header`：是否解析表头，默认为 `false`。布尔类型，例如：`'header'='true'`
+* `timeZone`：配置时区，没有默认值。用于指定文件中时间格式的时区。例如：`'timeZone' = 'Asia/Shanghai'`
+* `escape`：用于转义已加引号的值中的引号，默认值为”\“，例如：`'escape'='\'`
+* `multiLine`：是否启用多行字段解析，默认为 `false`。布尔类型。当设置为 true 时，解析器会正确处理被引号包围的字段中的换行符，将其作为字段内容的一部分而非行分隔符。这对于包含 JSON 格式数据、长文本描述、向量数据等可能跨行的字段特别重要。即使字段实际不包含换行符，启用此选项也能提供更健壮的解析，特别是处理包含大量特殊字符（如逗号、引号）的复杂字符串时。例如：`'multiLine'='true'`
+
+`USING Parquet | ORC | JSON | BSON`：
+
+* 无
+
+`FILES`：指定文件。例如：`files('part-00002.snappy.parquet','part-00003.snappy.parquet')`
+
+`SUBDIRECTORY`：指定子路径。例如：`subdirectory 'month=02' `
+
+`REGEXP <pattern>`：支持使用正则表达式匹配文件。需要注意的是，正则表达式匹配的目标是文件的**完整的对象存储路径**（如 's3://cz-udf-user/volume-data/1234321.csv.gz'），而不是以文件在 Volume 对象的相对路径。
+
+![](.topwrite/assets/20250124-160418.jpeg)
+
+匹配规则：
+
+* `.` - 匹配任意单个字符，不包括换行符
+* `*` - 匹配前面的元素零次或多次，经常与`.` 配合使用，如 `.* `组合表示匹配任意字符任意次数
+* `+` - 匹配前面的元素一次或多次，经常与`.` 配合使用，如 `.+ `表示匹配任意字符一次或多次
+* `?` - 匹配前面的元素零次或一次
+* `[abc]` : 匹配 a、b 或 c 中的任意一个字符
+* `[^abc]` : 匹配除了 a、b、c 之外的任意字符
+* `[a-z]` : 匹配小写字母 a 到 z
+* `[A-Z]` : 匹配大写字母 A 到 Z
+* `[0-9]` : 匹配数字 0 到 9
+
+例如：
+
+1. `REGEXP '.*.parquet'` 匹配以 `parquet` 后缀的文件
+2. `REGEXP '.*yellow_tripdata_202[0-4]-0[23].parquet' ` 匹配包含 `yellow_tripdata_` ，年份为 `2020` 到 `2024`，月份为 `02` 或 `03`，并且以 `.parquet` 结尾的文件名
+

+# 同义词
+## 概述
+
+同义词（synonym）是一个数据库对象，类似于给对象起一个别名，具有以下用途：
+
+* 当您需要在schema02中查询schema01的表t，但又不希望复制数据时，可以在schema02中为表t创建一个同义词sy\_t。这样，您就可以直接在schema02中查询sy\_t，而数据将实时与schema01中的表t保持一致。这是一种高效的数据管理策略，既保证了数据的一致性，又避免了不必要的数据重复。
+* 提供一个抽象层，保护客户端应用程序免受对基础对象的名称或位置所做的更改的影响。
+
+同义词属于 schema，与 schema 中的其他对象一样，同义词的名称必须在同一 schema 下唯一。支持为以下对象创建同义词：table、table stream、dynamic table、materialized view、volume、function。
+
+
+## 操作管理
+### 创建
+
+```SQL
+CREATE  [TABLE|VOLUME|FUNCITON] SYNONYM [schema_name.] synonym_name FOR object COMMENT''
+object ::=
+workspace_name.schema_name.object_name|schema_name.object_name｜object_name
+```
+
+* TABLE|VOLUME|FUNCTION：表示同义词对象类型。
+
+  * **TABLE**：这是默认选项。用于为 table、table stream、materialized view、dynamic table 命名同义词。在这些情况下，“table”关键字是可选的。
+  * **VOLUME**：为 volume 命名同义词时，必须明确指定此关键字。如果省略，系统将默认寻找同名的表格对象。
+  * **FUNCTION**：为 function 命名同义词时，此关键字是必填项。如果未指定，系统会默认寻找同名的 table 对象。
+
+* synonym\_name:同义词名称，遵循元数据规范
+
+* object：指定基对象的名称，支持workspace\_name.schema\_name\_2.object\_name、schema\_name\_2.name格式如果省略schema则使用当前schema中的对象
+
+
+### 删除
+
+```SQL
+DROP [TABLE|VOLUME|FUNCITON] SYNONYM [ IF EXISTS ] [ schema. ] synonym_name
+```
+
+* TABLE|VOLUME|FUNCTION：表示同义词的对象类型。
+
+  * **TABLE**：这是默认选项。用于为 table、table stream、materialized view、dynamic table 命名同义词。在这些情况下，“table”关键字是可选的。
+  * **VOLUME**：为 volume 命名同义词时，必须明确指定此关键字。如果省略，系统将默认寻找同名的表格对象。
+  * **FUNCTION**：为 function 命名同义词时，此关键字是必填项。如果未指定，系统会默认寻找同名的 table 对象。
+
+* if exists：可选。仅当同义词存在时，才有条件地删除该同义词。
+
+* schema：可选，指定同义词所在的 schema。如果未指定 schema，则使用当前会话的默认 schema。
+
+### 权限
+
+创建同义词需要 `CREATE SYNONYM` 权限。
+
+```SQL
+grant create synonym  on schema  scname to user uat_test_01;
+```
+
+删除同义词需要 `DROP` 权限。
+
+```SQL
+grant drop synonym on all synonyms in schema <schemaname> to user uat_test_01;
+grant create synonym  on schema  scname to user uat_test_01;
+```
+
+### 同义词查询权限
+
+同义词的权限与基对象的权限相同。授予对同义词的权限等同于授予对应基对象的权限。同样，授予对基对象的权限等同于授予对该对象的所有同义词的权限。如果向用户授予对同义词的权限，则该用户可以在行使该权限的 SQL 语句中使用同义词名称或基对象名称。
+
+### 列出同义词
+
+```SQL
+SHOW SYNONYMS [IN {SCHEMA scname | WORKSPACE wbname}] [WHRERE <expr>]
+```
+
+## 使用示例
+
+为 table 创建同义词
+
+```SQL
+--创建表
+CREATE TABLE `public`.students(
+  `name` string,
+  `class` string);
+--给表创建同义词
+CREATE SYNONYM students_sy for `public`.students;
+--查询同义词
+select * from students_sy;
+--删除同义词
+drop synonym students_sy;
+```
+
+为 table stream 创建同义词，其语法与为 table 创建同义词相同。
+
+```SQL
+create  synonym students_stream_synonym for public.students_stream;
+--删除同义词
+drop synonym students_stream_synonym;
+```
+
+为 dynamic table 创建同义词，其语法与为 table 创建同义词相同。
+
+```SQL
+create  synonym event_group_minute_sy for public.event_group_minute;
+--删除同义词
+drop synonym event_group_minute_sy;
+```
+
+为 materialized view 创建同义词，其语法与为 table 创建同义词相同。
+
+```SQL
+create SYNONYM event_group_mv_sy for event_group_mv;
+--删除同义词
+drop synonym event_group_mv_sy;
+```
+
+为 volume 创建同义词，其中 VOLUME 为必选关键字。如果不指定，则系统会默认寻找同名的表格对象。
+
+```SQL
+create volume synonym hz_csv_volume_sy for public.hz_csv_volume;
+--删除同义词
+drop volume synonym hz_csv_volume_sy;
+```
+
+为 function 创建同义词，其中 FUNCTION 为必选关键字。如果不指定，则系统会默认寻找同名的 table 对象。
+
+```SQL
+create function synonym s_swu_udf_upper_aliyun_java_upper for public.swu_udf_upper_aliyun_java_upper;
+--删除同义词
+drop function synonym s_swu_udf_upper_aliyun_java_upper;
+```
+
+## 获取同义词
+
+```SQL
+show synonyms in  public where synonym_name='students_sy';
++--------------+-------------------------+-------------+-----------------------+
+| synonym_name |       create_time       | target_type |       target_name     |
++--------------+-------------------------+-------------+-----------------------+

+## Table Stream 变化数据捕获
+
+Table Stream 是云器 Lakehouse 的一种功能，用于捕获表对象的变化数据。通过定义 Table Stream 对象，您可以基于现有表来记录和追踪数据的变化。该对象利用 Lakehouse Table 的多历史版本功能，在创建时会记录源表的指定版本（或最新版本）作为初始读取位置。当您使用 SQL 查询 Table Stream 时，它将返回从初始位点到当前最新版本的所有变化记录。
+
+以下是 Table Stream 的工作原理示意图：
+
+![Table Stream工作原理](.topwrite/assets/image_1699855189257.png)
+
+Table Stream 不会存储实际数据，仅记录和维护源表的数据版本位点。仅当使用 INSERT、DELETE、UPDATE、MERGE 等 DML 语句操作 Table Stream 时，其位点才会更新至最新的数据版本。
+
+### 应用场景
+
+1. **SQL ETL 任务**：使用 Table Stream 可以简化增量数据的识别，提高 ETL 任务的处理效率。传统 ETL 任务需要通过分区过滤或 WHERE 条件过滤增量数据，这在实时化场景下可能会产生额外的系统压力和资源消耗。Table Stream 基于数据版本识别变化数据，无需额外操作和计算即可捕获增量数据，从而提高 ETL 作业的效率，节省计算开销。
+2. **实时数据提供**：类似于数据库的CDC（变更数据捕获），Lakehouse数据平台的Table Stream可以捕获变化数据，并将这些数据以明细记录的形式持续同步给下游系统。
+
+## Table Stream类型
+
+Table Stream 有两种类型：
+
+1. **STANDARD 类型**：跟踪源对象的所有 DML 变化，包括插入、更新和删除（包括表截断）。这种类型提供行级别的变化，通过连接加工所有变化的 delta 数据来提供行级别增量。Table Stream 中的 delta 变化指的是在两个事务时间点之间发生的数据变化。例如，如果在 Table Stream 的 offset 之后，有一行被插入，然后被更新，那么 delta 变化就是一个新的行。如果在 Table Stream 的 offset 之后，有一行被插入，然后被删除，那么 delta 变化就是没有这一行。换句话说，delta 变化会反映源对象的最新状态，而不是历史变化。
+2. **APPEND_ONLY 类型**：仅记录对象的 INSERT 操作的数据。update 和 delete 操作不会记录。例如，最初在表中插入了 10 行，然后在点位没有移动的时候执行 delete 操作删除 5 行，Table Stream 仍然记录 10 行操作。
+
+## 使用Table Stream
+
+### 创建Table Stream
+
+您可以使用 `CREATE TABLE STREAM` 命令来创建 Table Stream。以下是一个示例：
+
+```SQL
+-- 创建测试表
+CREATE TABLE data_change_test (id INT, name STRING);
+INSERT INTO data_change_test VALUES (1, 'apple');
+ALTER TABLE data_change_test SET PROPERTIES ('change_tracking' = 'true');
+-- 在data_change_test上创建table stream，获取从当前时间开始插入的增量记录
+CREATE TABLE STREAM data_change_test_stream ON TABLE data_change_test
+WITH PROPERTIES('TABLE_STREAM_MODE' = 'APPEND_ONLY');
+
+-- 插入测试数据
+INSERT INTO data_change_test VALUES (2, 'banana');
+SELECT * FROM data_change_test; -- 可以查到两条记录
+SELECT * FROM data_change_test_stream; -- 查看stream可以查到一条记录，因为创建stream时指定的时间在id为1的记录之后
+-- 使用dml语句消费记录
+CREATE TABLE data_change_test_offset (id INT, name STRING);
+INSERT INTO data_change_test_offset SELECT id, name FROM data_change_test_stream; -- 写入到表中
+SELECT id, name FROM data_change_test_stream; -- 查询stream数据已经被消费
+```
+
+### 删除Table Stream
+
+您可以使用 `DROP TABLE STREAM` 命令来删除 Table Stream。以下是一个示例：
+
+```SQL
+DROP TABLE STREAM IF EXISTS data_change_test_stream;
+```
+
+### Table Stream 捕获数据变化的时效性
+
+Table Stream 根据对象的元数据修改提交时间来感知变化数据。具体时效性如下：
+
+- **DML 方式修改数据**：在 DML 任务成功结束后，变化数据即可在 Table Stream 对象中可见。
+- **批量导入（Bulkload）**：在批量导入任务成功结束后，变化数据即可在 Table Stream 对象中可见。
+- **流式导入**：通过 Ingestion Service 流式 API 写入数据，默认 1 分钟提交变化，变化数据即可在 Table Stream 对象中可见。注：对于流式写入的目标表本身进行 SQL 查询时是实时可见的，这里仅约束了基于该目标表的 Table Stream 可见性的时效。
+## 动态表与 Table Stream 的关系详解
+
+在云器 Lakehouse 中，动态表（Dynamic Table）与 Table Stream 是两种相互关联且至关重要的功能，均聚焦于增量数据处理领域，但它们在具体用途及工作模式上存在显著差异。
+
+### 一、动态表的定义与特点
+
+动态表是云器 Lakehouse 特有的数据对象，具备以下关键特性：
+
+* **增量计算能力**：能精准处理增量变化数据，拥有高效的增量刷新优化机制。
+* **自动化处理**：用户仅需定义业务逻辑，无需明确指定增量处理细节（例如按分区对齐或使用最大时间戳等），系统将自动完成增量计算优化工作。
+* **定期刷新**：支持设置刷新间隔，依据预设时间周期，从基表（Base Table）获取增量数据并执行计算任务。
+* **工作原理**：以“基于历史 T0 时刻已算结果，融合 T0 至 T1 时刻增量计算，同时为 T2 及后续时刻计算做铺垫”的增量形态开展计算。
+
+### 二、Table Stream 的定义与特点
+
+TABLE STREAM 专注于捕获表的数据变化，特点如下：
+
+* **变化数据捕获**：类似于数据库的 CDC（Change Data Capture）功能，全面记录表的 DML 更改操作，涵盖插入、更新与删除行为。
+* **版本跟踪**：借助 Lakehouse Table 的多历史版本特性，可指定记录源表的特定版本（或最新版本）作为初始读取起点。
+* **两种模式**：STANDARD 模式追踪所有 DML 变化；APPEND_ONLY 模式仅记录 INSERT 操作数据。
+* **位点更新**：仅记录和维护源表数据版本位点，不存储实际数据，执行 DML 语句操作 Stream 时同步更新位点信息。
+
+### 三、两者的关系与区别
+
+#### （一）功能层次
+
+* Table Stream 属于底层机制，核心任务是捕获表的变化数据。
+* 动态表则是建立在 Table Stream 之类的底层功能之上的高级特性，侧重于利用增量计算实现数据转换与加工。
+
+#### （二）数据处理方式
+
+* TABLE STREAM 仅聚焦于变化数据的捕获，不涉及数据计算环节。
+* 动态表会对捕获到的增量数据执行计算与转换操作，生成具有业务价值的结果。
+
+#### （三）支持关系
+
+* 动态表可借助 Table Stream 机制达成增量计算目标。
+* 在云器 Lakehouse 体系中，允许在动态表基础上创建 Table Stream，由此构建起复杂且高效的增量数据处理链路。
+
+#### （四）应用场景
+
+* **Table Stream**：适用于单纯的变化数据捕获场景以及实时数据同步任务，例如在需要快速感知源表数据变动并实时传递至其他系统的场景中发挥关键作用。
+* **动态表**：适用于对增量数据进行深度加工与转换的业务场景，比如在数据仓库中对每日新增订单数据进行多维度聚合计算，生成报表所需指标数据。
+
+#### （五）底层实现
+
+两者均依托于云器 Lakehouse 的 MetaService（元数据服务），该服务负责记录每张表的历史数据版本信息，为动态表和 Table Stream 的正常运行提供基础支撑。
+
+### 四、实际应用示例
+
+在实际业务场景中，动态表与 Table Stream 经常协同工作，形成完整且强大的增量数据处理方案：
+
+* **ETL 数据处理链**：先在源表创建 Table Stream 捕获变化数据，随后利用动态表对这些变化数据执行转换与聚合操作，最终将处理后的结果准确写入目标表。
+* **多级增量计算**：搭建一系列动态表，让每个动态表依次处理前一个表产生的增量数据，构建起高效的增量数据处理流水线，实现数据的逐级加工与提炼。
+* **实时数据分析**：借助 Table Stream 实时捕获业务系统数据变动，再通过动态表开展实时分析与计算，为业务决策层及时提供准确且具时效性的数据洞察，助力企业敏捷决策。

+LIMIT 50;
+
+-- 适用：快速发现数据质量问题
+```
+
+#### 场景 3：生成机器学习训练集（推荐 ROW）
+
+```sql
+-- 从用户行为表中随机抽取训练样本
+SELECT 
+    user_id,
+    behavior_type,
+    item_id,
+    timestamp
+FROM user_behavior 
+TABLESAMPLE ROW (20)  -- 精确 20% 随机采样
+LIMIT 1000000;
+
+-- 适用：保证样本的随机性和代表性
+```
+
+#### 场景 4：统计分析采样（推荐 ROW）
+
+```sql
+-- 估算平均订单金额
+SELECT 
+    AVG(total_amount) as avg_order_amount,
+    COUNT(*) as sample_count
+FROM large_orders_table 
+TABLESAMPLE ROW (5)  -- 5% 精确采样
+LIMIT 1000000;
+
+-- 适用：需要统计学上严格的随机采样
+```
+
+#### 场景 5：开发环境测试数据

+TABLESAMPLE ROW (1000 ROWS)  -- 精确 1000 行
+LIMIT 1000;
+
+-- 适用：开发和测试环境数据准备
+```
+
+### 进阶用法
+
+#### 结合 WHERE 条件
+
+```sql
+-- TABLESAMPLE 必须紧跟表名，然后才能使用 WHERE 条件
+SELECT * 
+FROM orders 
+TABLESAMPLE SYSTEM (10)
+WHERE order_date >
+
+#### 结合聚合分析
+
+```sql
+-- 在采样数据上进行聚合分析
+SELECT 
+    DATE_TRUNC('month', order_date) as month,
+    COUNT(*) as order_count,
+    AVG(total_amount) as avg_amount
+FROM large_orders
+TABLESAMPLE SYSTEM (5)
+GROUP BY DATE_TRUNC('month', order_date)
+ORDER BY month
+LIMIT 50;
+```
+
+#### 多表采样 JOIN
+
+```sql
+-- 对多个大表采样后 JOIN
+SELECT 
+    o.order_id,
+    c.customer_name,
+    o.total_amount
+FROM orders o
+TABLESAMPLE SYSTEM (10)
+JOIN customers c
+TABLESAMPLE SYSTEM (10)
+ON o.customer_id = c.customer_id
+LIMIT 100;
+```
+

+
+### 性能对比
+
+| 数据规模      | SYSTEM 模式 | ROW 模式  | 推荐             |
+| --------- | --------- | ------- | -------------- |
+| < 1 万行    | \~10ms    | \~15ms  | ROW（精确性更重要）    |
+| 1-10 万行   | \~50ms    | \~200ms | ROW 或 SYSTEM   |
+| 10-100 万行 | \~100ms   | \~2s    | SYSTEM（性能差异明显） |
+| > 100 万行  | ~200ms   | ~10s+  | SYSTEM（性能优势巨大） |
+
+*注：实际性能取决于硬件、数据分布等因素*
+
+***
+
+## 最佳实践
+
+### 1. 如何选择采样模式
+
+< 100万行？
+│  ├─ 是 → 需要精确随机性？
+│  │     ├─ 是 → 使用 ROW 模式
+│  │     └─ 否 → 使用 SYSTEM 模式（更快）
+│  └─ 否 → 使用 SYSTEM 模式（性能优先）
+```
+
+### 2. 性能优化建议
+
+#### ✅ 推荐做法
+
+```sql
+-- 1. 始终添加 LIMIT 子句
+SELECT * FROM large_table 
+TABLESAMPLE (10) 
+LIMIT 1000;  -- ✅ 限制最终返回行数
+
+-- 2. 在大表上优先使用 SYSTEM
+SELECT * FROM billion_rows_table 
+TABLESAMPLE SYSTEM (1)  -- ✅ 1% 采样已足够
+LIMIT 10000;
+
+-- 3. 先采样再 JOIN（减少 JOIN 数据量）
+SELECT a.*, b.*
+FROM (
+    SELECT * FROM large_table_a 
+    TABLESAMPLE (5) 
+    LIMIT 100000
+) a
+JOIN large_table_b b ON a.id = b.id
+LIMIT 1000;
+```
+
+#### ❌ 避免的做法
+
+```sql
+-- 1. 在小表上使用 SYSTEM 期望精确结果
+SELECT * FROM small_table_10_rows 
+TABLESAMPLE SYSTEM (30);  -- ❌ 可能返回 0 行或 10 行
+
+-- 2. 在大表上使用 ROW 不加 LIMIT
+SELECT * FROM billion_rows_table 
+TABLESAMPLE ROW (10);  -- ❌ 性能极差，可能返回 1 亿行
+
+-- 3. 过度采样（接近 100%）
+SELECT * FROM large_table 
+TABLESAMPLE (95);  -- ❌ 接近全表扫描，失去采样意义
+```
+
+### 3. 采样精度建议
+
+| 需求     | 推荐采样比例    | 说明            |
+| ------ | --------- | ------------- |
+| 快速预览   | 0.1% - 1% | 足够了解数据结构      |
+| 数据质量检查 | 5% - 10%  | 平衡性能和覆盖率      |
+| 统计估算   | 10% - 20% | 保证统计显著性       |
+| 机器学习训练 | 20% - 50% | 根据数据量和模型复杂度调整 |
+
+### 4. 常见问题解答
+
+**Q1: 采样比例超过 100% 会怎样**？
+
+```sql
+SELECT * FROM test TABLESAMPLE (150) LIMIT 50;
+-- A: 会报错！ClickZetta 要求采样比例必须在 0-100 之间
+-- 错误信息: tablesample percentage number should be greater than 0 and less than 100
+```
+
+**Q2: 采样行数超过表总行数会怎样**？
+
+```sql
+SELECT * FROM test TABLESAMPLE (100 ROWS) LIMIT 50;  -- 表只有 10 行
+-- A: 会返回全表数据（10 行）
+```
+
+**Q3: 空表采样会返回什么**？
+
+```sql
+SELECT * FROM empty_table TABLESAMPLE (50) LIMIT 50;
+-- A: 返回空结果集，不会报错
+```
+
+**Q4: 视图和表的采样有差异吗**？
+
+```sql
+-- 都支持，但视图可能性能稍差（需要先物化）
+SELECT * FROM my_view TABLESAMPLE ROW (10) LIMIT 50;
+```
+
+**Q5: 如何获得可重复的采样结果**？
+
+```sql
+-- TABLESAMPLE 不支持 SEED，如需可重复采样：
+SELECT * FROM (
+    SELECT *, ROW_NUMBER() OVER (ORDER BY id) as rn
+    FROM my_table
+) WHERE rn % 10 = 0  -- 每 10 行取 1 行
+LIMIT 50;
+```
+
+***
+
+## 限制和注意事项
+
+### 使用限制
+
+1. **不支持的场景**
+   * ❌ 不支持在子查询的 WHERE 子句中使用
+   * ❌ 不支持在 CTE (WITH 子句) 定义中使用
+   * ❌ 不支持在物化视图定义中使用
+
+2. **语法限制**
+   * ⚠️ 必须在 FROM 子句中紧跟表名使用
+   * ⚠️ TABLESAMPLE 必须在 WHERE 子句之前
+   * ⚠️ 不能与 `FOR UPDATE` 一起使用
+   * ⚠️ 百分比采样的范围必须在 0-100 之间（不包括0和100）
+
+3. **性能注意事项**
+   * ⚠️ ROW 模式在超大表（> 1000万行）上可能非常慢
+   * ⚠️ 即使采样 1%，ROW 模式也需要扫描全表
+
+### 数据一致性
+
+* 🔄 **非确定性**：每次执行返回不同的结果
+* 📊 **统计偏差**：SYSTEM 模式在数据分布不均时可能有偏差
+* ⏱️ **时效性**：采样时看到的是当时的数据快照
+
+### 最佳实践总结
+
+| 场景    | 数据量    | 推荐模式   | 采样比例   | LIMIT      |
+| ----- | ------ | ------ | ------ | ---------- |
+| 数据预览  | 任意     | SYSTEM | 1-5%   | 100-1000   |
+| 质量检查  | 任意     | SYSTEM | 5-10%  | 1000-10000 |
+| 统计分析  | < 100万 | ROW    | 10-20% | 适当         |
+| 统计分析  | > 100万 | SYSTEM | 5-10%  | 适当         |
+| ML训练集 | < 100万 | ROW    | 20-50% | 适当         |
+| ML训练集 | > 100万 | SYSTEM | 10-30% | 适当         |

+# TABLE STREAM 功能介绍
+
+## 概述
+
+Table Stream 是 Lakehouse 架构中的一种对象，它能够记录对表进行的数据操作语言（DML）的更改，包括插入、更新和删除操作。Table Stream 还提供有关每次更改的元数据信息，使得用户可以利用这些信息采取相应的操作。它可以记录表中两个事务时间点之间的行级别更改，类似于关系数据库的变更数据捕获（CDC）功能。下游系统可以通过 SQL 语句消费 Table Stream，当下游的 DML 操作包含 Table Stream 时，会导致 Table Stream 的位点自动偏移。支持在 Table、Dynamic Table、Materialized View、External Table(Kafka) 创建 Table Stream.
+
+同时也支持在 External Volume 上创建 Volume Stream，用于监听外部对象存储（如 OSS）中的文件变更事件。
+
+## Table、Dynamic Table 和 Materialized View 的 TABLE STREAM OFFSET
+
+Table Stream Offset 是一种存储流的偏移量（即源对象的当前事务版本）的机制。偏移量决定了 Table Stream 返回的变化记录的范围。以下是 Table Stream Offset 的一些特点：
+
+1. 当创建 Table Stream 时，会对源对象的每一行进行一个初始快照，以初始化一个偏移量。随后，Table Stream 会记录在此快照之后发生的 DML 变化的信息。
+2. Table Stream 本身不包含任何表数据，只存储源对象的偏移量，并利用源对象的版本历史来返回变化记录。
+3. Table Stream 的偏移量可以在创建时指定，也可以在消费时更新。指定偏移量的方法使用时间戳。
+4. Table Stream 的偏移量位于源对象的两个表版本之间。查询 Table Stream 时，会返回在偏移量之后和当前时间之前提交的事务所造成的变化。
+
+## Table、Dynamic Table和Materialized View的TABLE 版本控制
+
+在 Lakehouse 中，每当对表进行插入、更新或删除操作时，都会生成一个新的表版本（也称为快照）。这些版本是不可变的，意味着一旦创建，它们就不能被修改。每个版本都包含了自上一版本以来所有数据变更的记录。Table Stream 是基于 TABLE 版本实现的。当创建一个 Stream 时，它会跟踪源表的所有后续版本，并允许用户查询自从创建 Table Stream 以来发生的变更。
+
+![](.topwrite/assets/image_1704374346251.png)
+
+上面的例子显示了一个源表在时间线上有10个已提交的版本。Table Stream的偏移目前在表版本v3和v4之间。当查询（或消费）流时，返回的记录包括从表版本v4开始，即表时间线中流偏移之后的版本，到v10结束，即时间线中最近提交的表版本，包括这两个版本之间的最小更改集。
+
+## Table、Dynamic Table和Materialized View的TABLE STREAM支持的类型
+
+1. STANDARD 模式：在此模式下，可以跟踪源对象的所有 DML 变化，包括插入、更新和删除（包括表截断）。这种模式提供行级别的变化，是通过将所有变化的 delta 数据进行连接加工来提供行级别增量。Table Stream 中的 delta 变化指的是在两个事务时间点之间发生的数据变化。
+2. APPEND\_ONLY 模式：只记录对象的 INSERT 操作的数据。对于 UPDATE 和 DELETE 操作不会进行记录。
+
+## Table、Dynamic Table和Materialized View的TABLE STREAM 记录数据的范围
+
+这个时间范围取决于源对象的数据保留期和数据延长期（DATA\_RETENTION\_DAYS）。数据保留期是指源对象的历史数据可以通过 Time Travel 查询的时间长度。
+
+## 消费 TABLE STREAM
+
+Table Stream 的消费者是指下游 SQL 中含有 DML 语句则会消费 Table Stream 数据。当下游的 DML 操作包含 Table Stream 时，会使 Table Stream 的位点自动偏移。执行 DQL 操作不会使位点偏移，例如 SELECT 语句。一个源对象可以有多个 stream 同时跟踪它的变化。每个 Table Stream 都可以有不同的 offset，即不同的起始时间点。每个 Table Stream 都可以被不同的消费者（consumer）使用，例如不同的任务、脚本或其他机制。消费者可以通过执行 DML 事务来消费 Table Stream 中的变化数据，从而更新 Table Stream 的 offset。
+
+## TABLE STREAM 中的元数据字段
+
+当查询 Table Stream 时，返回的结果集中包含附加的元数据列，包含变化的类型、提交的版本、和提交的时间。具体字段如下：
+
+* `__change_type`：包含 DML 操作（INSERT、DELETE、UPDATE\_BEFORE、UPDATE\_AFTER）
+* `__commit_version`：数据提交的版本
+* `__commit_timestamp`：数据提交的时间
+
+## 注意事项
+
+* 创建 Table Stream 之前，必须在基表上执行以下操作开启变更跟踪：`ALTER TABLE table_name set PROPERTIES ('change_tracking' = 'true');`
+* 通过[实时上传数据](java_reference/realtime-upload.md)写入的数据一分钟之后才可以读取，Table Stream 只能读取已经提交的数据。实时任务写入的数据需要等待 1 分钟才能确认，所以 Table Stream 也要等 1 分钟才能看到。
+

+## Volume Stream 功能介绍
+
+Volume Stream 是 Table Stream 的一种特殊形式，它构建在 External Volume 的 Directory Table 之上。Directory Table 是 External Volume 开启目录功能（DIRECTORY = (ENABLE = TRUE)）后自动维护的一张元数据表，记录了 Volume 中所有文件的路径、大小、修改时间等信息。Volume Stream 通过追踪 Directory Table 的数据变化，来感知外部存储（如对象存储 OSS、S3 等）中文件的新增与删除事件。
+
+与普通 Table Stream 追踪用户表的 DML 变更不同，Volume Stream 追踪的是文件层面的变化。Directory Table 的更新依赖云厂商的消息队列服务（如阿里云 MNS、AWS SQS 等）将对象存储的事件通知实时推送至系统，从而驱动 Directory Table 刷新，进而使 Volume Stream 感知到文件的新增与删除。
+
+典型使用场景包括：应用日志分析、IoT 设备数据接入、图片/音视频元数据提取、多源文件归档等。通过 Volume Stream 作为增量驱动器，配合调度任务实现"只处理新增/变更文件"的高效增量模式，避免全量扫描带来的性能与成本开销。
+
+***
+
+## 前置准备
+
+在创建 Volume Stream 之前，需要完成以下云服务及数据库对象的准备工作（以阿里云-杭州 region 为例）。
+
+> 注意：当前版本(2026.03)仅支持阿里云和 AWS
+
+### STEP-1：创建 MNS 队列
+
+1. 进入 [阿里云 MNS 控制台](https://mns.console.aliyun.com/region/cn-hangzhou/queues)。
+2. 创建队列，输入名称（例如 `volume-stream-20251203`），选择**普通队列**，其他配置保持默认。
+
+### STEP-2：创建 OSS 事件通知
+
+1. 打开 OSS Bucket 管理页，选择 **数据处理 → 事件通知**。
+2. 创建规则：
+   * 根据需要选择事件类型（建议勾选 `ObjectCreate:*`、`ObjectRemoved:*`）。
+   * 根据需要配置对象匹配前缀/后缀。
+   * 通知目标选择 STEP-1 中创建的 MNS 队列。
+
+### STEP-3：创建 RAM 策略和角色
+
+**a. 创建权限策略**（[策略管理页](https://ram.console.aliyun.com/policies)），参考配置如下：
+
+```json
+{
+  "Version": "1",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Action": [
+        "oss:GetObject",
+        "oss:HeadBucket",
+        "oss:PutObject",
+        "oss:DeleteObject",
+        "oss:ListObjects"
+      ],
+      "Resource": [
+        "acs:oss:oss-cn-hangzhou:<账号ID>:<bucket名称>",
+        "acs:oss:oss-cn-hangzhou:<账号ID>:<bucket名称>/*"
+      ]
+    },
+    {
+      "Effect": "Allow",
+      "Action": [
+        "mns:GetQueueAttributes",
+        "mns:SetQueueAttributes"
+      ],
+      "Resource": "acs:mns:cn-hangzhou:<账号ID>:/queues/<队列名称>"
+    },
+    {
+      "Effect": "Allow",
+      "Action": [
+        "mns:DeleteMessage",
+        "mns:ReceiveMessage",
+        "mns:PeekMessage",
+        "mns:BatchPeekMessage"
+      ],
+      "Resource": "acs:mns:cn-hangzhou:<账号ID>:/queues/<队列名称>/messages"
+    }
+  ]
+}
+```
+
+**b. 创建角色**（[角色管理页](https://ram.console.aliyun.com/roles)）：
+
+1. **信任主体类型**：选择"云账号"。
+2. **信任主体名称**：选择"其他云账号"，输入 Lakehouse 平台的账号 ID（`1384322691904283`）。
+3. **角色名称**：例如 `CzVolumeStreamRole`。
+4. 将 STEP-3a 中创建的权限策略授予该角色。
+
+### STEP-4：创建 Storage Connection
+
+**a. 创建连接**：
+
+```sql
+CREATE STORAGE CONNECTION conn_hz
+    TYPE OSS
+    REGION = 'cn-hangzhou'
+    ROLE_ARN = 'acs:ram::<账号ID>:role/<角色名称>'
+    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com';
+```
+
+**b. 获取 External ID，用于后续配置信任策略**：
+
+```sql
+DESCRIBE CONNECTION conn_hz;
+```
+
+记录返回结果中的 `externalId` 字段值。
+
+**c. 更新角色信任策略**（将 `externalId` 填入）：
+
+```json
+{
+  "Statement": [
+    {
+      "Action": "sts:AssumeRole",
+      "Condition": {
+        "StringEquals": {
+          "sts:ExternalId": "<describe connection 返回的 externalId>"
+        }
+      },
+      "Effect": "Allow",
+      "Principal": {
+        "RAM": [
+          "acs:ram::1384322691904283:root"
+        ]
+      }
+    }
+  ],
+  "Version": "1"
+}
+```
+
+***
+
+## Volume Stream 语法
+
+### 创建 External Volume
+
+在创建 Volume Stream 之前，必须先创建一个带有消息通知配置的 External Volume：
+
+```sql
+CREATE [OR REPLACE] EXTERNAL VOLUME <volume_name>
+  LOCATION '<oss://bucket/path/>'
+  USING CONNECTION <connection_name>
+  NOTIFICATION = (
+    QUEUE_TYPE = 'ALICLOUD_MNS',
+    QUEUE_NAME = '<volume-stream-20251203>', -- STEP-1 创建的队列名称
+    VIRTUAL_CLUSTER = 'DEFAULT'
+  )
+  DIRECTORY = (ENABLE = TRUE)
+  RECURSIVE = TRUE;
+```
+
+**参数说明**：
+
+* `<volume_name>`：External Volume 的名称。
+* `LOCATION`：OSS 存储路径，格式为 `oss://<bucket>/<prefix>/`。
+* `USING CONNECTION <connection_name>`：关联 STEP-4 中创建的 Storage Connection。
+* `NOTIFICATION`：消息通知配置块。
+  * `QUEUE_TYPE`：消息队列类型，当前支持 `ALICLOUD_MNS`。
+  * `QUEUE_NAME`：STEP-1 中确认的 MNS 队列名称。
+  * `VIRTUAL_CLUSTER`：虚拟集群名称，默认填写 `DEFAULT`。
+* `DIRECTORY = (ENABLE = TRUE)`：开启目录模式，Volume Stream 依赖此配置。
+* `RECURSIVE = TRUE`：递归监听路径下所有子目录的文件变更。
+
+### 创建 Volume Stream
+
+```sql
+CREATE [OR REPLACE] STREAM <name>
+  ON VOLUME <volume_name>;
+```
+
+**参数说明**：
+
+* `<name>`：Volume Stream 的名称。
+* `<volume_name>`：要监听的 External Volume 名称。
+
+***
+
+## 注意事项
+
+* 当前版本(2026.03) 仅支持阿里云和 AWS。
+* RAM 角色的信任策略中必须正确配置 `sts:ExternalId`，否则 Lakehouse 平台无法代入该角色读取 MNS 消息和 OSS 文件。
+* Volume Stream 只能读取已完成上传的文件。由于事件通知存在一定的传递延迟（通常约 1 分钟），文件上传后需等待约 1 分钟才能在 Volume Stream 中查询到对应的变更记录。
+* 与 Table Stream 类似，Volume Stream 通过消费点位（offset）记录已处理的事件位置，消费行为通常是一个 DML 操作（非 SELECT），每次消费后点位会向前推进，避免重复消费。
+
+***
+
+## 示例：增量解析 OSS 图片
+
+以下示例展示了一个 Volume Stream 配置流程，用于监听 `sh-oss-derek` bucket 下 `dish-images/` 目录中的文件新增与删除事件。利用图像识别函数只消费 `INSERT` 和 `UPDATE_AFTER` 两种事件（新增图片 + 替换图片），跳过 DELETE 和 UPDATE\_BEFORE，调用 AI 函数识别后写入结果表，DML 执行完自动推进消费点位。
+
+> 注意：此案例中用到的云厂商角色 ARN，图像识别函数等需要自定义，系统并未默认提供。
+
+### 1. 创建 Storage Connection
+
+```sql
+CREATE STORAGE CONNECTION conn_sh_oss
+  TYPE OSS
+  REGION = 'cn-shanghai'
+  ROLE_ARN = 'acs:ram::1450476637304722:role/czvolumestreamrole' -- 需替换成自己的 RoleARN
+  ENDPOINT = 'oss-cn-shanghai.aliyuncs.com';
+```
+
+### 2. 获取 External ID 并更新信任策略
+
+```sql
+DESCRIBE CONNECTION conn_sh_oss;
+```
+
+将返回的 `externalId`（例如 `EOKskml6SMldYOb9`）填入角色的信任策略后保存。
+
+### 3. 创建基础对象
+
+```sql
+-- 1. 创建 External Volume（OSS 图片桶，开启 MNS 事件通知）
+CREATE EXTERNAL VOLUME vol_dish_images
+  LOCATION 'oss://sh-oss-derek/dish-images/'
+  USING CONNECTION conn_sh_oss
+  NOTIFICATION = (
+    QUEUE_TYPE    = 'ALICLOUD_MNS',
+    QUEUE_NAME    = 'cz-queue-mns-ossevent',
+    VIRTUAL_CLUSTER = 'DEFAULT'
+  )
+  DIRECTORY = (ENABLE = TRUE)
+  RECURSIVE = TRUE;
+
+-- 2. 创建识别结果表
+CREATE TABLE IF NOT EXISTS dish_recognition_results (
+    file_path          VARCHAR        COMMENT '图片相对路径',
+    file_url           VARCHAR        COMMENT '图片完整 OSS 地址',
+    file_size          BIGINT         COMMENT '文件大小（字节）',
+    last_modified_time TIMESTAMP      COMMENT '文件最后修改时间',
+    recognized_content VARCHAR        COMMENT 'AI 识别结果',
+    change_type        VARCHAR        COMMENT '触发事件类型 INSERT/UPDATE_AFTER',
+    commit_version     BIGINT         COMMENT 'Stream 消费版本号',
+    processed_at       TIMESTAMP      COMMENT '处理时间'
+);
+
+-- 3. 创建 Volume Stream（STANDARD 模式，可感知新增和替换）
+CREATE STREAM IF NOT EXISTS str_dish_images
+  ON VOLUME vol_dish_images
+  WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
+```
+
+### 4. 增量消费
+
+```
+-- 增量识别节点：只处理 INSERT（新图）和 UPDATE_AFTER（替换图），自动推进 offset
+INSERT INTO dish_recognition_results
+SELECT
+    relative_path   AS file_path,
+    url   AS file_url,
+    size   AS file_size,
+    last_modified_time,
+    public.fc_image_to_text('dish_recognition', url) AS recognized_content,
+    __change_type  AS change_type,
+    __commit_version  AS commit_version,
+    current_timestamp() AS processed_at
+FROM str_dish_images
+WHERE __change_type IN ('INSERT', 'UPDATE_AFTER')  -- 只处理新增和替换，跳过 DELETE / UPDATE_BEFORE
+  AND (
+       lower(relative_path) LIKE '%.jpg'
+    OR lower(relative_path) LIKE '%.jpeg'
+    OR lower(relative_path) LIKE '%.png'
+    OR lower(relative_path) LIKE '%.webp'
+  );                       
+```
+
+### 5. 查询识别结果
+
+```
+-- 查看最新识别结果
+SELECT
+    file_path,
+    recognized_content,
+    change_type,
+    processed_at
+FROM dish_recognition_results
+ORDER BY processed_at DESC
+LIMIT 20;
+
+-- 统计每类菜品识别数量
+SELECT
+    recognized_content,
+    COUNT(*) AS cnt
+FROM dish_recognition_results
+GROUP BY recognized_content
+ORDER BY cnt DESC;
+
+```

+# 任务开发概念说明
+
+任务开发模块是云器 Lakehouse 向开发者提供的一个可视化开发页面。在该模块下，用户可进行任务的组织编排、开发、调度配置、运行测试以及提交发布等操作。
+
+## 开发概念说明
+
+| **概念** | **定义**                                                                                                                                    |
+| ------ | ----------------------------------------------------------------------------------------------------------------------------------------- |
+| 任务     | 简单节点：单个具体的任务类型，例如 SQL、Python 等                                                                                                              |
+|        | 复杂流程类节点：由多个节点组成的一组节点，例如组合节点等。复杂流程类节点中的参数、调度配置项统一进行配置管理。                                                                                      |
+| 任务组    | 任务组是云器 Lakehouse 提供的一个虚拟管理概念。可以将任务添加至任务组内进行集中的管理，包括可视化拖拽编排依赖关系、配置任务组参数、批量设置调度、批量提交等操作。**说明**：若您需要对一组任务进行 DAG 方式的拖拽管理，或者对一批任务链路进行复制改造，建议使用任务组功能。 |
+
+## 依赖关系：节点依赖
+
+依赖关系是挂载在节点上的。无论是简单节点还是复杂流程类节点，均以一个独立节点作为依赖点。
+
+**注意**：无论是在任务下直接创建任务节点，还是在任务组内进行统一管理，依赖关系始终是在任务节点级别上的，即节点之间的依赖，不存在任务组之间建立依赖的能力。
+
+^
+
+## 场景说明
+
+* 支持用户直接在「任务」下创建各类任务节点，并通过调度配置中的调度依赖来创建节点之间的依赖关系进行开发。
+* 同时也支持用户在「任务组」下新建或添加已有的节点，对一批任务进行组织编排，包括配置任务组级别的参数、可视化拖拽任务之间的依赖关系等。
+
+| **开发方式** | **目标用户**               | **场景优势**                                 | **场景使用限制与差异**                                                   |
+| -------- | ---------------------- | ---------------------------------------- | --------------------------------------------------------------- |
+| 创建任务     | 业务相对比较创新或追求短平快节奏的团队。   | 无需创建复杂的业务关系，只需创建好节点间依赖后快速跑通流程。适合短平快的场景。  | * 不支持批量操作，比如批量修改任务调度时间、使用集群等。                                  |
+| 任务组内管理任务 | 业务数仓团队成熟规范，多以业务思路去组织内容 | 可以以业务场景的方式管理相关的一批任务节点，同时支持以可视化方式拖拽依赖关系 | 当前暂不支持实时任务的管理。<br>一个任务节点只能在一个任务组内管理。<br>任务组需要提交后，任务组参数才能被任务真正使用。 |
+
+^
+
+### 名词解释
+
+#### 任务组
+
+任务组是云器 Lakehouse 提供的一个虚拟管理概念。可以将任务添加至任务组内进行集中的管理，包括可视化拖拽编排依赖关系、配置任务组参数、批量设置调度、批量提交等操作。
+
+* **说明**：若您需要对一组任务进行 DAG 方式的拖拽管理，或者对一批任务链路进行复制改造，建议使用任务组功能。更多可参考 [任务组 ](task_group.md)。
+
+#### 任务
+
+在云器 Lakehouse 上封装了不同类型的任务节点，类型包括实时多表同步、离线同步、实时同步、SQL 开发、Python、Shell、虚拟节点等。您可以根据业务需要，选择合适的任务类型进行开发。
+
+#### 参数
+
+* **任务组参数**：在任务组内创建的参数，仅对任务组内的任务进行全局管理。
+* **调度参数**：在任务调度时使用的参数。
+* **临时参数**：在任务临时执行时使用的参数。
+
+#### 调度配置：
+
+* 当前仅支持周期调度。
+* **依赖方式**：区间依赖，即用下游任务实例的起止时间范围与上游实例的起止时间范围进行重叠判断。更多依赖关系可参考 [任务调度依赖关系](task_scheduling_dependency.md)。

+# 任务组
+
+## 概念
+
+任务组是开发板块内用以管理一组任务列表的虚拟业务管理组。您可以使用任务组对一系列任务进行组织编排，包括添加/创建任务节点、创建任务节点之间的依赖关系、配置任务组参数以及统一批量提交的操作。
+
+本文为您介绍如何创建、编辑、提交任务组，以及任务组的复制操作。
+
+## 使用限制
+
+1）任务组内仅支持添加/创建周期任务，暂不支持实时任务。
+
+2）任务组参数只有在被提交发布后，任务节点中引用的该参数才能使用任务组参数配置的变量值参与执行。
+
+例如，若任务组参数是 aaa=2023，任务里使用了该参数，但是任务组未提交。那么任务在做周期执行时，实例参数将显示为空。
+
+3）一个任务节点只能归属于一个任务组。
+
+4）下游链路复制：只能复制在该工作空间下的所有节点，若该下游链路有其他工作空间的任务节点，不会被复制出来。
+
+## 应用场景
+
+### 场景一：任务批量复制与依赖关系管理
+
+当您需要对一组有依赖关系的任务进行批量复制，并在新的任务中创建新的依赖关系时，可以使用任务组复制功能实现。
+
+![](.topwrite/assets/91c6efc6cd/3c6fcb545a6b507a072943955259ae593b4f1892.jpeg =700)
+
+将需要复制并建立新依赖关系的任务组添加至任务组1内，对任务组1进行复制操作后，复制得到的任务组2将包含以下内容：
+
+1. 对任务组1内所有任务的批量复制。
+2. 任务组1内有依赖关系的节点（如节点B、C、D、E、F）在任务组2内会维持原来的依赖关系。
+3. 任务组外但与组内节点有依赖关系的节点（如节点A、G），将维持原本的依赖关系。
+
+### 场景二：任务链路改造与自定义变量批量修改
+
+当您需要对当前任务链路中的任意一分支进行改造，同时需要批量修改任务里的自定义变量时，可以通过节点下游链路复制功能结合任务组功能实现。
+
+![](.topwrite/assets/91c6efc6cd/f8dfd42b7ace23593c3f7d3d79bff8eb46d2a1f9.jpeg =751)
+
+在任意一个节点上（该节点可以是归属于某一个任务组，也可以是独立的），点击「下游链路复制」时，会将该节点及其下游所有节点进行批量复制。
+
+## 创建任务组
+
+创建任务组前，您可以结合自身的业务情况，先规划设计好符合自身业务诉求的业务流程。以下为创建任务组的详细步骤。
+
+1）创建任务组
+
+**方式一**：单击左侧导航栏的「开发」；鼠标悬浮在+上，点击「任务组」
+
+**方式二**： 单击左侧导航栏的「工作区」；鼠标悬浮在新建按钮上，点击「任务组」
+
+2）在新建任务组对话框中，输入任务组名称
+
+3）点击确定
+
+![](.topwrite/assets/image_1722251763584.png =434)
+
+创建完成后：
+
+* 您可以在当前任务组内管理任务节点，包括新建/添加已有任务到该任务组内
+* 任务组内的所有任务开发完成后，可直接提交任务组至生产环境。
+
+## 编辑任务组
+
+支持用户在列表和 DAG 两种模式下设计任务组内管理的任务节点和依赖关系。
+
+![](.topwrite/assets/image_1722251928404.png)
+
+1）新建/添加节点：两种模式下均支持在任务组创建新的任务节点，或添加已有的任务至任务组内。
+
+* **DAG图模式**
+
+  * 添加已有任务：点击右侧「添加已有任务」后，可将列表中的任务拖至DAG画布区域；
+  * 添加新任务：在「添加新任务」下方，拖拽任意一个任务节点至画布区域后，会弹出该节点的创建弹窗。用户输入任务名称，以及所在目录后，即成功创建一个新节点至该任务组上。
+
+DAG 图模式下，点击右侧下方「已添加的任务」即可在图中高亮显示出该任务节点。
+
+* **列表模式**
+
+  * 点击列表模式右上角「添加」按钮后，可选择是添加已有任务还是新任务。
+
+新建/添加节点成功后，您需要进入该节点的操作界面进行代码的编辑工作。
+
+2）创建任务之间的依赖关系：
+
+* DAG图模式下：可以通过拖拽依赖线的方式设置节点调度依赖。当然，您也可以进入节点的调度配置界面，来手动编辑节点依赖关系。
+* 列表模式下新建的节点，其调度依赖可根据代码血缘关系自动或手动设置。
+
+3）任务组参数：任务组下的全局参数。当任务组提交至生产环境后，这些参数会自动作用于引用它们的任务节点上。在任务组参数生效前已提交的任务节点，需要重新提交后才可以引用该参数。
+
+* 点击任务组内操作区域的「参数」tab，进入任务组参数配置界面中。
+* 点击新建按钮，在弹窗内输入参数名称和参数取值。内置参数取值详情请见[任务参数](task_param.md)
+
+  ![](.topwrite/assets/image_1722252018555.png =497)
+
+创建任务组参数后，使用方法如下：
+
+* 在任务节点的SQL代码中输入${任务组参数名称}，或在调度配置的参数配置中输入参数名；
+
+  ![](.topwrite/assets/image_1722252076469.png =496)
+
+* 在「取值来源」下拉框里选择任务组参数
+
+  ![](.topwrite/assets/image_1722252102342.png =472)
+
+创建且引用任务组参数后：
+
+* 任务组提交至生产环境后，应用的任务节点才可以使用任务组参数的参数值
+* 变更后的任务组参数如需在任务节点里生效，需重新提交任务节点
+
+### 批量提交调度时间
+
+可使用批量编辑调度时间的功能，批量修改任务组内所有（或选定）任务的调度时间，以减少逐个配置的操作成本。具体操作如下：
+
+1）点击批量修改调度时间
+
+* DAG编辑模式下：鼠标悬浮在批量按钮上时，选择「编辑调度时间」
+  ![](.topwrite/assets/image_1736303777548.png =498)
+* 列表模式下：选择需要批量修改的目标任务后，点击编辑调度时间。
+
+2）批量编辑调度时间
+选择批量修改的调度时间，这里操作同任务调度里的调度配置，具体操作可参考[任务开发调度](taskdevelop.md)
+![](.topwrite/assets/image_1736303843406.png =499)
+
+3）确定提交批量操作
+
+## 提交任务组
+
+任务组编辑创建完成后，需要将其提交至生产环境，其管理的任务才可以引用任务组内的参数信息。同时，任务组也提供了批量提交任务节点的功能。
+
+1）点击右上角提交按钮，弹出任务组提交弹窗，同时可以支持批量提交任务组内的任务列表。
+
+2）DAG图模式下，鼠标悬浮在批量按钮上方，显示批量提交任务，该功能仅支持批量提交任务组内的任务，不会将任务组本身的参数和管理信息提交至生产环境中。
+
+## 相关问题
+
+Q1：为什么任务组提交后，提交按钮不能再次点击了
+
+任务组提交后，若未发生任何变更（即状态未变为“已提交，有修改”），则不支持再次提交。若需要批量提交任务组内的任务信息，可通过两种方式提交
+
+方案一：在任务内直接操作提交
+
+方案二：在任务组DAG图模式下，点击批量操作下的批量提交任务
+
+任务组状态变更条件：
+
+* 对任务组内的任务进行增删的操作
+* 对任务组参数进行增删改查的操作

+# 任务参数
+
+> 特别注意：参数功能目前处于灰度阶段，完整的功能仅对部分客户开放使用。可使用文末的方式来验证是否支持。
+
+## 什么是任务参数
+
+### 为什么需要参数？
+
+在日常数据开发中，我们经常遇到这样的场景：
+
+* 每天处理前一天的数据：`WHERE dt = '2023-09-21'`
+* 每月统计上月数据：`WHERE month = '2023-08'`
+* 查询特定城市数据：`WHERE city = 'Shanghai'`
+
+如果把日期、城市等信息写死在代码中，任务运行时就无法动态适应变化。**任务参数**就是为了解决这个问题而设计的。
+
+### 参数的核心价值
+
+* **动态替换**：任务运行时自动替换参数值。
+* **灵活配置**：支持常量、时间表达式、系统参数。
+* **复用性强**：一次定义，多处使用。
+* **易于维护**：修改参数无需改动代码逻辑。
+
+### 基本概念

+| 参数定义 | 自定义参数    | 指用户在代码中，自定义输入，引用的参数。其格式固定为 ${自定义参数名}               | ${my\_param}                         |
+| 参数赋值 | 常量       | 指固定不变的取值，比如字符串和数字，用于给自定义参数赋值                       | abcd 或 1234                          |
+| 参数赋值 | 系统内置参数   | 指由系统内置的一系列参数表达式，用来方便用户获取需要通过计算获取的动态的信息，比如任务实例的计划时间 | sys\_plan\_datetime                  |

+
+## 快速开始
+
+### 三步快速上手
+
+**第1步：在代码中使用参数**
+
+```SQL
+SELECT * FROM sales_table WHERE city = '${city}' AND dt = '${yesterday}';
+```
+
+**第2步：配置参数取值**
+点击"参数"按钮，系统会自动识别出 `city` 和 `yesterday` 两个参数，为它们赋值：
+
+* `city` = `Shanghai`
+* `yesterday` = `$[yyyy-MM-dd, -1d]`
+
+**第3步：运行验证**
+点击“运行”，系统会将参数替换后执行：
+
+```SQL
+SELECT * FROM sales_table WHERE city = 'Shanghai' AND dt = '2023-09-21';  
+
+-- 假设今天是2023-09-22
+```
+
+### 关键要点
+
+* 参数格式固定为：`${参数名}`。
+* 参数名只能包含字母、数字、下划线。
+* 参数要在定义中使用内置参数或时间表达式等赋值，然后在代码中引用。不能在代码中直接引用内置参数。
+* 参数替换时，只替换 `${}` 内的内容。
+* 如需在SQL中加引号，需自行添加，比如：`'${city}'`。
+
+## 参数类型与作用域
+
+系统提供两种参数类型，支持不同的使用场景：
+
+### 任务参数
+
+**特点**：
+
+* 作用范围：仅当前任务
+* 使用场景：任务特定的配置
+
+**适用情况**：
+
+* 单个任务独有的参数
+* 需要精细控制的场景
+* 临时性的参数配置
+
+**创建方式**：
+方式一：在脚本中输入 ${自定义参数} 后，系统会自动将自定义参数添加至「参数」弹窗内。
+方式二：点击「参数」按钮，在弹窗内输入信息。

+
+| 配置项  | 说明           | 示例                           |
+| ---- | ------------ | ---------------------------- |
+| 参数名称 | 参数的唯一标识      | city、yesterday               |
+| 取值来源 | 选择"任务"或"任务组" | 任务                           |
+| 参数取值 | 参数的实际值       | Shanghai、$\[yyyy-MM-dd, -1d] |
+| 加密取值 | 勾选后取值以密文显示   | 用于密码等敏感信息                    |
+| 是否忽略 | 勾选后不进行参数替换   | 将 ${var} 作为普通文本              |
+
+**示例**：
+```SQL
+-- 在某个具体任务中使用
+
+SELECT * FROM table WHERE status = '${task_status}';
+```
+
+### 任务组参数
+
+**特点**：
+
+* 作用范围：任务组内所有任务
+* 使用场景：多任务共享的配置
+
+**适用情况**：
+
+* 多个任务共用的参数（如项目代码、环境标识）
+* 全局性的配置（如数据库名称）
+* 需要统一管理的参数
+
+**创建方式**：
+在任务组页面点击「参数」，在弹框中点击「新建」，填写参数名称、参数值。
+
+![](/.topwrite/assets/image_1760699887513.png =680)
+
+如果要在具体任务中使用任务组参数，需要在任务参数定义的取值来源中做显式切换，指明该参数取值来源于任务组。
+
+![](/.topwrite/assets/image_1760699557999.png =680)
+
+**示例**：
+```SQL
+-- 任务组参数：db_name = warehouse_prod
+
+-- 任务A
+SELECT * FROM ${db_name}.table_a;
+
+-- 任务B
+SELECT * FROM ${db_name}.table_b;
+
+-- 两个任务都使用同一个db_name参数
+```
+
+## 参数两种配置方法
+
+### 方法一：基于代码自动识别
+
+直接在脚本中输入 `${参数名}`，系统会自动识别并添加到参数列表。
+
+**优点**：快速、直观，参数名不易拼写错误。
+```SQL
+-- 输入以下代码
+SELECT * FROM table WHERE city = '${city}' AND dt = '${dt}';
+-- 系统自动识别出 city 和 dt 两个参数
+```
+
+### 方法二：手动创建后再使用
+
+点击"参数"按钮，在弹窗中点击"新建"，手动输入参数信息。
+
+**优点**：可以提前定义参数，适合规划性强的场景。
+
+## 参数在不同运行方式下的作用效果
+
+### 临时运行（点击"运行"按钮）
+
+* 弹窗提示输入参数值
+
+  ![](/.topwrite/assets/image_1761284431760.png =680)
+
+* 本次运行生效，不影响已保存的参数配置
+
+* 适合调试和验证
+
+### 周期调度运行（自动定时调度）
+
+* 使用已保存的参数配置
+* 根据调度时间动态计算参数值
+* 适合生产环境
+
+## 系统内置参数
+
+系统预置了一系列常用参数，可直接用于参数赋值，无需手动计算。
+
+请特别注意内置参数无法在代码中被直接引用。
+
+### 日期时间类参数
+
+| 参数名                  | 格式                    | 说明            | 示例（基准时间2023-09-22 18:00:00） |
+| -------------------- | --------------------- | ------------- | --------------------------- |
+| bizdate              | yyyyMMdd              | 业务日期（计划时间-1天） | 20230921                    |
+| sys\_biz\_day        | yyyy-MM-dd            | 业务日期          | 2023-09-21                   |
+| sys\_biz\_datetime   | yyyy-MM-dd HH\:mm\:ss | 业务时间          | 2023-09-21 18:00:00             |
+| sys\_plan\_day       | yyyy-MM-dd            | 计划日期          | 2023-09-22                   |
+| sys\_plan\_datetime  | yyyy-MM-dd HH\:mm\:ss | 计划时间          | 2023-09-22 18:00:00             |
+| sys\_plan\_timestamp | 13位时间戳                | 计划时间戳（毫秒）     | 1695463200000               |
+
+### 任务信息类参数
+
+| 参数名              | 说明    | 示例         | 注意事项     |
+| ---------------- | ----- | ---------- | -------- |
+| sys\_task\_id    | 任务ID  | 1002       | 仅调度运行时支持 |
+| sys\_task\_name  | 任务名称  | demo\_task | 仅调度运行时支持 |
+| sys\_task\_owner | 任务负责人 | UAT\_TEST  | 仅调度运行时支持 |
+
+### 使用示例
+
+```SQL
+-- 示例1：使用业务日期
+SELECT * FROM table WHERE dt = '${dt}';
+-- 参数配置：dt = sys_biz_day
+-- 调度时间2023-09-22，实际执行：WHERE dt = '2023-09-21'
+
+-- 示例2：使用计划时间戳
+SELECT * FROM table WHERE create_time >= ${start_ts};
+-- 参数配置：start_ts = sys_plan_timestamp
+-- 结果：WHERE create_time >= 1695463200000
+
+-- 示例3：Python任务中使用
+task_id = '${task_id}'
+print(f"当前任务ID: {task_id}")
+-- 参数配置：task_id = sys_task_id
+```
+
+### 使用建议
+
+1. **业务日期场景**：优先使用 `bizdate` 或 `sys_biz_day`
+2. **需要时分秒**：使用 `sys_biz_datetime` 或 `sys_plan_datetime`
+3. **时间戳计算**：使用 `sys_plan_timestamp`
+4. **审计日志**：使用 `sys_task_*` 系列参数记录任务信息
+

+
+## 时间表达式详解
+
+时间表达式是参数系统的核心功能，支持灵活的时间格式化和偏移计算。
+
+### 基础语法
+
+```Plain
+$[时间格式]                    # 基本格式化
+$[时间格式, 偏移量]             # 带偏移量
+$[时间格式, 偏移1, 偏移2, ...]  # 多个偏移量
+```
+
+### 时间格式元素
+
+时间表达式遵循 **ISO-8601 标准**，严格区分大小写。
+
+| 元素   | 含义             | 示例     |
+| ---- | -------------- | ------ |
+| yyyy | 四位年份           | 2023   |
+| yy   | 两位年份           | 23     |
+| MM   | 两位月份（01-12）    | 9      |
+| dd   | 两位日期（01-31）    | 22     |
+| HH   | 24小时制小时（00-23） | 18     |
+| mm   | 分钟（00-59）      | 59     |
+| ss   | 秒（00-59）       | 49     |
+| .SSS | 毫秒             | 0.377  |
+| ZZ   | 时区             | +08:00 |
+
+### 常用格式组合
+
+```SQL
+$[yyyy-MM-dd]                         → 2023-09-22
+$[yyyyMMdd]                           → 20230922
+$[yyyy/MM/dd]                         → 2023/09/22
+$[yyyy-MM-dd HH:mm:ss]                → 2023-09-22 18:00:00
+$[yyyyMMddHHmmss]                     → 20230922180000
+$[HH:mm:ss]                           → 18:00:00
+$[yyyy-MM-dd HH:mm:ss.SSSZZ]          → 2023-09-22 18:00:00.377+08:00
+```
+
+### 常见错误
+
+```SQL
+❌ $[YYYY-MM-DD]           # 大写Y不支持
+❌ $[yyyy-mm-dd]           # 小写m是分钟不是月份
+❌ $[yyyy-MM-dd hh:mm:ss]  # 小写h是12小时制
+✅ $[yyyy-MM-dd HH:mm:ss]  # 正确写法
+```
+
+### 时间偏移量
+
+支持对时间进行增减操作，使用直观的单位缩写。
+
+| 单位 | 缩写  | 全称                | 示例    |
+| -- | --- | ----------------- | ----- |
+| 毫秒 | ms  | milli/millisecond | 400ms |
+| 秒  | s   | sec/second        | 400s  |
+| 分钟 | m   | min/minute        | 3m    |
+| 小时 | h   | hour              | 1h    |
+| 天  | d   | day               | 2d    |
+| 月  | mon | month             | 1mon  |
+| 年  | y   | year              | -1y   |
+
+### 偏移量示例
+
+```SQL
+-- 单个偏移量
+$[yyyy-MM-dd, -1d]                           → 昨天
+$[yyyy-MM-dd, 1d]                            → 明天
+$[yyyy-MM-dd, -1mon]                         → 上个月今天
+$[yyyy-MM-dd, -1y]                           → 去年今天
+$[HH:mm:ss, -1h]                             → 1小时前
+$[HH:mm:ss, 30m]                             → 30分钟后
+
+-- 多个偏移量（按顺序依次计算）
+$[yyyy-MM-dd, -1y, -1mon, -1d]               → 去年上个月昨天
+$[yyyy-MM-dd HH:mm:ss, -1d, -2h, -30m]       → 昨天减2小时再减30分钟
+$[yyyyMMdd, 1mon, -7d]                       → 下月退7天
+```
+
+### 完整示例
+
+假设当前计划时间为：**2023-09-22 18:30:00**
+
+```SQL
+-- 基础格式
+SELECT '${today}' as today;
+-- 参数配置：today = $[yyyy-MM-dd]
+-- 结果：2023-09-22
+
+-- 昨天
+SELECT '${yesterday}' as yesterday;
+-- 参数配置：yesterday = $[yyyy-MM-dd, -1d]
+-- 结果：2023-09-21

+
+-- 1小时前
+SELECT '${one_hour_ago}' as one_hour_ago;
+-- 参数配置：one_hour_ago = $[HH:mm:ss, -1h]
+-- 结果：17:30:00
+```

+
+### 时间戳函数
+
+#### `timestamp()` - 毫秒时间戳
+
+**语法**：
+
+```Plain
+timestamp()                                 # 当前计划时间戳
+timestamp(offset1, offset2, ...)            # 带偏移量的时间戳
+```
+
+**返回值**：13位毫秒时间戳
+
+**示例**：
+```SQL
+-- 当前时间戳
+SELECT ${current_ts} as current_ts;
+-- 参数配置：current_ts = timestamp()
+-- 假设当前2023-09-22 18:00:00，结果：1695463200000
+
+-- 昨天此刻时间戳
+SELECT ${yesterday_ts} as yesterday_ts;
+-- 参数配置：yesterday_ts = timestamp(-1d)
+-- 结果：1695376800000
+
+-- 一周前减2小时的时间戳
+SELECT ${ts} as ts;
+-- 参数配置：ts = timestamp(-1w, -2h)
+```
+
+#### `biz_timestamp()` - 业务时间戳（基于00:00:00）
+
+**语法**：
+
+```Plain
+biz_timestamp()                             # 今天00:00:00时间戳
+biz_timestamp(offset1, offset2, ...)        # 带偏移量
+```
+
+**返回值**：13位毫秒时间戳，基于当天00:00:00计算

+## 实际场景示例
+
+### 场景1：处理昨天的分区数据
+
+**需求**：每天凌晨处理前一天的订单数据
+
+```SQL
+-- SQL任务
+INSERT OVERWRITE TABLE order_summary PARTITION(dt='${yesterday}')

+GROUP BY order_id;
+```
+
+**参数配置**：
+
+* `yesterday` = `$[yyyy-MM-dd, -1d]`
+
+**说明**：假设任务在2023-09-22执行，参数替换为 `2023-09-21`
+
+***
+
+### 场景2：生成月报（上月数据统计）
+
+**需求**：每月1号生成上月的销售报表
+
+```SQL
+-- SQL任务
+SELECT 
+    product_id,

+* `last_month_start` = `first_day_of_month('yyyy-MM-dd', '-1mon')`
+* `last_month_end` = `last_day_of_month('yyyy-MM-dd', '-1mon')`
+
+**说明**：假设在2023-09-01执行
+
+* `last_month_start` → `2023-08-01`
+* `last_month_end` → `2023-08-31`

+```
+
+**参数配置**：
+
+* `last_week_monday` = `first_day_of_week('yyyy-MM-dd', '-1w')`
+* `last_week_sunday` = `last_day_of_week('yyyy-MM-dd', '-1w')`
+
+**说明**：假设在2023-09-25（周一）执行
+
+* `last_week_monday` → `2023-09-18`（上周一）
+* `last_week_sunday` → `2023-09-24`（上周日）
+
+***
+
+### 场景4：获取每周二的数据

+WHERE dt = '${this_tuesday}'
+GROUP BY promotion_id;
+```
+
+**参数配置**：
+
+* `this_tuesday` = `get_day_of_week('yyyy-MM-dd', 2)`
+
+**说明**：
+
+* 假设任务在2023-09-22（周五）执行 → `2023-09-19`（本周二）
+* 假设任务在2023-09-25（周一）执行 → `2023-09-26`（本周二）

+
+```SQL
+-- SQL任务
+SELECT 
+    order_id,
+    order_time,
+    amount
+FROM orders
+WHERE order_timestamp >
+
+**错误用法**：
+```SQL
+-- ❌ 缺少引号导致SQL语法错误
+WHERE city = ${city}        # 替换后：WHERE city = Shanghai（语法错误）
+
+-- ❌ 多余的引号
+WHERE id = '${user_id}'     # 替换后：WHERE id = '12345'（类型错误）
+```
+
+### Q4：临时运行和调度运行的参数有什么区别？
+
+| 维度     | 临时运行         | 调度运行                  |
+| ------ | ------------ | --------------------- |
+| 参数来源   | 弹窗手动输入       | 参数配置中的取值              |
+| 生效范围   | 仅本次运行        | 每次调度都生效               |
+| 时间基准   | 点击运行的时刻      | 调度计划时间                |
+| 任务信息参数 | 不支持（无实际任务实例） | 支持 sys\_task\_\* 系列参数 |
+| 适用场景   | 调试、验证        | 生产环境自动运行              |
+
+**注意**：临时运行时输入的参数值**不会保存**到参数配置中，参数配置中只保存参数赋值的逻辑（表达式或常量）。
+
+***
+
+### Q5：如何验证参数配置是否正确？
+
+**使用简单查询验证**
+
+```SQL
+SELECT '${lastDay}' as lastDay;
+```
+
+参数配置：`lastDay = add_days('yyyy-MM-dd', -1)`
+
+**查看执行日志** 执行后查看日志中的实际执行SQL，确认参数是否正确替换。
+
+如果返回昨天的日期（如 `2023-09-21`），说明参数功能正常。
+
+***
+
+### Q6：Python任务中如何使用参数？
+
+**示例**：
+```Python
+# 定义参数（使用字符串变量）
+yesterday = '${yesterday}'
+start_ts = ${start_ts}
+task_name = '${task_name}'
+
+# 使用参数
+print(f"处理日期：{yesterday}")
+print(f"开始时间戳：{start_ts}")
+
+# 在SQL中使用
+sql = f"""
+    SELECT * FROM table 
+    WHERE dt = '{yesterday}'
+      AND create_time >= {start_ts}
+"""
+```
+
+**参数配置**：
+
+* `yesterday` = `$[yyyy-MM-dd, -1d]`
+* `start_ts` = `biz_timestamp()`
+* `task_name` = `sys_task_name`
+
+**注意**：
+
+* 字符串类型参数需要加引号：`'${yesterday}'`
+* 数值类型参数不加引号：`${start_ts}`
+
+***
+
+### Q7：如何处理月末日期偏移问题？
+
+**问题**：1月31日减1个月应该是12月31日，但有些月份没有31日
+
+**解决方案**：使用 `last_day_of_month()` 函数
+
+```SQL
+-- 推荐写法（明确要上月最后一天）
+SELECT '${last_month_end}' as last_month_end;
+-- 参数配置：last_month_end = last_day_of_month('yyyy-MM-dd', '-1mon')
+-- 始终返回上月最后一天
+```
+
+***
+
+### Q8：如何调试复杂的参数表达式？
+
+**技巧1：逐步验证**
+
+```SQL
+-- 先验证基础表达式
+SELECT '${base_date}' as base_date;
+-- base_date = $[yyyy-MM-dd]
+
+-- 再添加偏移量
+SELECT '${offset_date}' as offset_date;
+-- offset_date = $[yyyy-MM-dd, -1mon]
+
+-- 最后添加多个偏移量
+SELECT '${final_date}' as final_date;
+-- final_date = $[yyyy-MM-dd, -1mon, -7d]
+```
+
+**技巧2：使用注释说明**
+
+```SQL
+SELECT 
+    '${report_start}' as report_start,  -- 上月第一天
+    '${report_end}' as report_end,      -- 上月最后一天
+    '${last_year_date}' as last_year_date  -- 去年同期
+FROM table;
+```
+
+在参数配置中也添加说明，方便后续维护。
+
+***
+
+### Q9：参数加密后如何修改？
+
+**步骤**：
+
+1. 点击参数配置，找到加密的参数
+2. 取消勾选"加密取值"
+3. 参数值会明文显示，可以修改
+4. 修改完成后重新勾选"加密取值"
+
+**注意**：加密仅用于显示，不影响参数的实际使用。
+
+^
+
+***
+
+## 附：如何确认是否支持完整参数功能
+
+使用以下验证SQL：
+
+```SQL
+SELECT '${lastDay}' as lastDay;
+```
+
+**参数配置**：
+
+* `lastDay` 赋值填写 `add_days('yyyy-MM-dd', -1)`
+
+**校验逻辑**：
+```
+检查参数替换、任务执行返回结果是否正常。
+如果返回正常，则说明在灰度范围内、支持完整的参数功能，否则说明不支持。
+假定当前日期是2023-11-12，正常的返回值会是2023-11-11。

+# 任务调度依赖关系
+
+## 概述
+
+任务调度依赖是不同任务节点之间，形成上下游依赖关系的配置操作。既支持同工作空间内配置任务依赖关系，也支持配置跨工作空间依赖其它工作空间下的任务节点。您可根据实际业务逻辑所需的依赖场景，配置任务的上下游依赖，
+
+## 依赖特殊说明
+
+**当前的依赖限制**
+
+* 不支持任务类型：实时同步、多表实时同步、动态表、流式SQL。
+* 不允许配置环形依赖。
+* 当被依赖的节点未上线时，下游节点不支持上线。
+* 若当前节点被其他任务所依赖，且该节点下游的周期调度任务处于正常调度中，则当前节点不允许直接下线。
+
+## 依赖配置入口
+
+![](.topwrite/assets/image_1756107294537.png)
+进入具体的任务后，点击任务工具栏「调度」，进入调度配置弹窗页面。
+点击调度依赖可选择依赖的任务，配置依赖策略等行为操作。
+
+## 实例依赖关系说明
+
+云器Lakehouse支持分钟、小时、天三种类型的调度任务互相依赖，调度类型不同，任务执行的周期数不同。当周期任务运行时，下游周期实例会依赖上游周期实例。
+当前系统内提供三种依赖方式：
+
+**默认依赖**：系统内默认的挂载关系为区间依赖，即用下游任务实例的起止时间范围去与上游实例的起止时间范围进行重叠判断后，并基于以下规则判断具体依赖的实例范围：
+
+* 同周期：即同周期进行依赖。
+* 大周期依赖小周期：比如天任务依赖小时任务，下游实例覆盖上游任务几个实例，就依赖哪几个上游实例。
+* 小周期依赖大周期：比如小时任务依赖天任务，下游实例被上游哪个实例覆盖，就依赖哪个上游实例。
+
+**向前依赖**：下游任务实例寻找上游任务实例依赖时只会依赖距离其定义时间往前（等于或早于本实例的定时时间）的所有上游实例。
+
+**向前就近依赖**：当用户选定向前就近依赖时，下游任务实例寻找上游任务实例依赖时会遵循就近原则，即依赖距离其定时执行时间最近（等于或早于本实例的定时时间）的上游实例。
+
+> 注意：下游任务一旦挂载依赖，则需要满足两个条件才可以触发实例的正常运行，即上游任务实例正常运行成功，以及达到自身的调度时间。
+

+### 常见问题
+
+问题1：已提交至生产环境中的周期任务流程中，某个节点发现发现实例运行错误后，将该任务下线后替换成其他任务再提交运行后，为什么错误的实例还是会有。
+
+回答：已运行完成的任务实例不会因为该任务的下线而下线。

+
+| 参数       | 说明                                                                                |
+| -------- | --------------------------------------------------------------------------------- |
+| 调度周期     | 每天调度：选中后该调度每天都会执行。 每月指定天调度：用户可自行选择每月指定的日期执行调度。 每周指定天调度：用户按照周粒度指定具体日期执行。           |
+| 调度频率     | 执行1次：用户选择执行1次后，只需要配置开始调度时间即可。&#xA;执行多次：用户选择执行多次后，还需要配置调度间隔时长、开始调度时间、结束调度时间，排除时间设置 |
+| 每次调度间隔时长 | 选择执行多次时，可支持用户自定义每次执行的间隔时长，从1分钟，到12个小时的跨度均支持选择                                     |
+| 开始调度时间   | 每天实例开始执行的时间                                                                       |

+| 排除时间设置   | 若包含了用户设定了排除时间，那么在该时间范围内不会生成相应的周期调度实例                                              |
+| 生效时间     | 任务从哪一天开始生效                                                                        |
+| 失效时间     | 任务从哪一天开始失效                                                                        |
+| 预览调度时间   | 点击预览调度时间，可查看配置调度后具体的运行时间。                                                         |
+
+#### 实例信息
+
+Studio支持**次日生效**、**发布后生效**两种实例生成方式。
+
+| 参数         | 说明                                                                                                          |
+| ---------- | ----------------------------------------------------------------------------------------------------------- |
+| 实例生成方式     | 发布后生效：即时转实例的方式，发布后，会即刻生成当天的任务实例、按照配置的调度时间运 次日生效：在隔天再调度运行任务的实例                                               |
+| 实例遇错重跑     | 实例重跑属性，主要从数据幂等性等考虑，设定任务实例是否可以被重跑。请按需设置。 运行成功或失败后皆可重跑 运行成功后不可重跑，运行失败后可重跑 运行成功或失败皆不可重跑                        |
+| 自动重跑次数     | 自定义重跑次数                                                                                                     |
+| 实例超时时长     | 不开启 自定义&#xA;任务的实例运行时间超过设定时长后，则会直接置为失败。取值改动后，只对定时时间在任务提交时间之后的新实例生效                                           |
+| 预览调度时间     | 点击预览调度时间，可查看配置调度后具体的运行时间。                                                                                   |
+| 参数配置       | 点击“新增参数”可以新增一个参数 点击加载代码中参数，会自动加载在代码中已经使用的参数 代码中，引用参数的方式为：'${bizdate}' ，注意这里的引号是英文的引号 备注：更多的系统内置参数，会在后续版本中支持 |
+| 调度等待时长     | 任务实例在到达调度定时时间后，若等待时长超过设定值，且仍处于等待上游任务结束的状态（即未进入运行状态，也未运行结束），系统将直接判定该任务实例运行失败，以防止其长时间不运行、产生调度堆积。              |
+| 延迟运行空跑跳过时长 | 基于任务实例进入运行状态的时间与配置的定时时间之间的差异进行判断。若该差值超过设定时间，择直接进行空跑跳过操作，并将该实例状态置为成功。                                        |
+
+#### 调度依赖
+
+复杂的生产任务，通常存在上下游的依赖关系，比如DWD加工任务需要依赖ODS层任务。在“调度依赖”配置，可以添加当前任务的依赖上游任务。支持的方式有两种：父节点的文件名称、父节点产出的表名
+
+依赖策略：当前支持默认策略、向前依赖、向前就近依赖策略。具体策略对应的实例生成方式可见[任务调度依赖关系](task_scheduling_dependency.md)
+
+![](.topwrite/assets/image_1756191826292.png =660)
+
+#### 任务产出
+
+有两种方式配置任务的产出信息
+
+方式一：通过上文提及的代码自动解析，可自动生成输出表名
+
+方式二：通过搜索表名、手动添加
+
+![](.topwrite/assets/image_1690523641208.png =437)

+| z    | 时区名称     | zone-name      | Pacific Standard Time; PST |
+| O    | 本地化时区偏移量 | offset-O      | GMT+8; GMT+08:00; UTC-08:00; |
+| X    | 时区偏移量   | offset-X       | Z; -08; -0830; -08:30; -083015; -08:30:15; |
+| Z    | 时区偏移量   | offset-Z       | +0000; -0800; -08:00; |
+| ''  | 单引号       | literal        | ’              |
+
+#### 符号使用示例
+
+- 年份:
+  - `yyyy`: 四位数年份表示法，例如 2022。
+  - `yy`: 两位数年份表示法，例如 22。
+
+- 月份:
+  - `M`: 单位数月份表示法，例如 3、12。
+  - `MM`: 双位数月份表示法，例如 03、12。
+
+- 当月天数:
+  - `d`: 单位数当月日期表示法，例如 5、20。
+  - `dd`: 双位数当月日期表示法，例如 05、20。
+
+- 小时 (24小时制):
+  - `H`: 单位数24小时制小时表示法，例如 1、23。
+  - `HH`: 双位数24小时制小时表示法，例如 01、23。
+
+- 分钟:
+  - `m`: 单位数分钟表示法，例如 4、59。
+  - `mm`: 双位数分钟表示法，例如 04、59。
+
+- 秒:
+  - `s`: 单位数秒钟表示法，例如 8、59。
+  - `ss`: 双位数秒钟表示法，例如 08、59。
+
+- 毫秒/微秒:
+  - `S`: 支持1-9位数字，表示毫秒（前3位）、微秒（中间3位）和纳秒（后3位）。CZ目前只支持微秒精度，因此解析时间字符串时纳秒会被丢弃，生成时间字符串时纳秒部分则会置零。不足9位时，从右向左降低精度。
+
+#### 示例
+
+以下是一些使用上述符号的日期时间格式示例：
+
+- `yyyy-MM-dd HH:mm:ss.SSSS`: 2022-01-10 10:05:02.1232
+- `yyyy/MM/dd HH:mm:ss.SSSS`: 2022/01/10 10:05:0

+# Time Travel
+
+Time Travel功能可以让您像时间旅行一样访问时间窗口中的任何时间点的数据，包括已更新或删除的数据、恢复已删除的表或恢复已过期的表。通过Time Travel，您可以轻松查看历史版本数据，从而更好地了解数据的变更历史。
+
+![Time Travel示意图](.topwrite/assets/image_1708936936399.png)
+
+如上图所示，表中原来有一条数据，经过insert、update、delete等操作后，共有四个版本。当指定的版本在v0-v1之间时，Time Travel将返回v0的数据。通过指定版本，您可以查看历史版本数据。
+
+## Time Travel功能支持的操作
+
+* 使用undrop命令恢复已删除的表
+* 使用restore命令恢复现有表或dynamic表到指定版本
+* 查询表或dynamic表已更新或删除之前的数据
+* 查看表或dynamic表的版本历史
+* 创建表流（table stream）或使用table\_changes获取表或dynamic表的变化
+
+# Time Travel保留期限设置
+
+Time Travel保留期限决定了您可以访问多久以前的数据。例如，如果Time Travel保留期限设置为7天，那么您可以访问过去7天内的任何时间点的数据。超过7天后，您将无法使用Time Travel访问过期的数据，且数据会被物理删除。
+Lakehouse表的历史状态默认保留周期1天(24小时），您可以通过Time Travel查询1天内的历史版本。请注意如果设置的时间更长存储费用会增加
+
+如需保留更长周期的历史版本，您可以为每个表设置不同的数据保留周期，以满足不同的业务需求。num的设置范围为0-90。
+
+  * ```SQL
+    ALTER TABLE tablename SET PROPERTIES ('data_retention_days'='num');
+    ```
+
+## 恢复删除的对象
+
+请参考[恢复删除数据](UNDROP-TABLE.md)文档，了解如何使用undrop命令恢复已删除的表。
+
+## 恢复数据到指定版本
+
+请参考[RESTORE命令](restore.md)文档，了解如何使用restore命令将现有表或dynamic表恢复到指定版本。
+
+## 查询历史数据
+
+请参考[TIME TRAVEL](TIMETRAVEL.md)文档，了解如何查询表或dynamic表已更新或删除之前的数据。
+
+## 查看对象的版本历史
+
+请参考[DESC HISTORY](desc-history.md)文档，了解如何查看表或dynamic表的版本历史。
+
+## 使用table stream和table\_changes获取表的变化
+
+* 请参考[使用TABLE CHANGES获取数据变化](sql_functions/table_functions/table_changes.md)文档，了解如何使用table\_changes获取表或dynamic表的变化。
+* 请参考[使用TABLE STREAM获取数据变化](tablestream_summary.md)文档，了解如何使用table stream获取表或dynamic表的变化。

+# 概述
+
+TPC-DS（Transaction Processing Performance Council - Decision Support）是一种由交易处理性能评估委员会（TPC）发布的基准测试标准，旨在评估决策支持系统（Decision Support Systems，DSS）的性能。相较于TPC-H更适合评估传统的查询和报表性能，TPC-DS包含了对数据集的分析报告、交互查询、数据挖掘等复杂应用场景，更接近真实的数据仓库业务分析场景。
+
+本报告为您提供了云器Lakehouse与Spark SQL在TPC-DS测试集10TB规模上的测试结果，结论如下：

+
+# 测试过程
+
+在测试中，我们选择了TPC-DS基准测试中的103个复杂SQL查询，对10TB的数据集进行性能测试。测试结果包括每个查询在云器Lakehouse和Spark SQL中的执行时间，以及两者的性能对比。
+
+## Spark SQL
+
+在元数据服务中创建TPC-DS数据表，使用Parquet文件格式，分区设置与Lakehouse保持一致。
+
+同时，从云器Lakehouse中导出TPC-DS 10TB测试数据，以数据文件形式保存至对象存储服务，以保证双方的测试数据一致。然后在Spark中使用INSERT INTO语句读取数据文件并写入Spark定义的数据表中。
+
+* 运行TPC-DS 103个查询时，Spark添加了以下参数：
+
+```SQL
+--spark 生产环境大作业必调参数之一。在处理TPCDS-10T规模的数据时，若使用默认的最大并发数200，会因规模偏小而导致大量task内存占用过高，并且极易触发shuffle spill，进而使Spark运行缓慢。经测试，将该参数值调整为2000后，观察到spill大幅减少。因此，我们决定采用2000这一参数值，以优化Spark的运行性能。
+set spark.sql.shuffle.partitions = 2000;spark默认值为200
+```
+
+
+## 云器Lakehouse
+
+### 创建集群和表
+
+使用云器Lakehouse XLARGE Virtual Cluster在阿里云OSS上进行测试，所有表均使用默认存储格式。
+
+```SQL
+create vcluster if not exists XLARGE_CLUSTER vcluster_size='XLARGE' vcluster_type='Analytics'  AUTO_RESUME=TRUE AUTO_SUSPEND_IN_SECOND=300 min_replicas=1 max_replicas=1;
+```

+
+## Trino
+
+TPC-H数据以CSV格式文件上传至对象存储服务，使用EMR集群通过外表方式导入到Hive内表（Parquet格式，LZ4压缩）。Hive内表与云器Lakehouse表使用相同的分桶和排序设置。
+
+所有数据表通过ANALYZE收集统计信息后，执行TPC-H的查询。

+# 场景案例1：基于静态分区的ETL任务增量改造（无维度表或维度表不变）
+
+## 业务背景
+
+针对传统按天调度的全量批处理任务（T+1模式），通过动态分区表技术实现增量处理优化。改造后可达成：
+
+* 数据时效提升：支持小时级/分钟级调度间隔
+* 资源利用率优化：减少冗余计算约60%-80%
+* 运维效率提升：支持分区级数据修复与回溯
+
+## 场景特征
+
+适用对象需满足：
+
+1. 业务时间对齐自然日：如订单交易、日志采集等典型日切场景
+2. 固定调度时段：建议在数据就绪时段（如00:30-01:00）集中处理
+3. 分区字段标准化：源表需包含标准日期分区字段（如event_day/pt/ds等）
+
+## 改造方案：使用分区动态表
+
+#### 1. 创建分区动态表
+
+在创建分区动态表时，通过定义参数 `SESSION_CONFIGS()['dt.args.event_day']` 来指定源表要扫描的分区或者分区范围。此参数在 SQL 加工逻辑中使用，通过 `SESSION_CONFIGS()['dt.arg.xx']` 进行定义，表示查询源表的分区字段。
+
+* 参数格式：`SESSION_CONFIGS()['dt.args.xx']`，其中 `xx` 是自定义的参数名称，必须以 `dt.args.` 开头，以避免与系统内部字段冲突。
+* 等价表达：与传统调度中的 `SELECT * FROM source_table WHERE pt = ${bizdate}` 等价。例如，`SESSION_CONFIGS()['dt.args.pt']` 等价于 `pt = ${bizdate}`。
+
+#### 2. 动态表刷新
+
+在刷新动态表时，使用以下命令指定分区值：
+
+```SQL
+REFRESH DYNAMIC TABLE target_table PARTITION (pt = ${bizdate});
+```
+
+* 对应传统操作：等同于传统的 `INSERT OVERWRITE target_table PARTITION (pt = ${bizdate})`。
+
+## 改造实施步骤
+
+### 将离线任务转换为增量任务
+
+本节将指导用户如何将原有的离线任务转换为增量任务，以实现更高效的数据处理。以下是一个基于“传统数据库”的具体操作步骤，适用于业务逻辑按天对齐和按天调度刷新的场景。
+
+#### 步骤1：任务改造
+
+原始SQL
+
+```SQL
+CREATE TABLE target PARTITIONED BY (ds);
+
+-- 20250101 调度
+SQL :=
+INSERT OVERWRITE TABLE target (ds='20250101')
+SELECT * 
+FROM 
+    src_1 AS t1
+LEFT OUTER JOIN 
+    src_2 as t2 WHERE t2.ds = '2025/01/01' AND t2.category = 'A'
+ON t1.id = t2.id;
+
+-- 20250102 调度
+SQL :=
+INSERT OVERWRITE TABLE target (ds='20250102')
+SELECT * 
+FROM 
+    src_1 AS t1 
+LEFT OUTER JOIN 
+    src_2 as t2 WHERE t2.ds = '2025/01/02' AND t2.category = 'A'
+ON t1.id = t2.id;
+```
+
+首先，需要将原始SQL中的所有由调度引擎传入的参数`${bizdate}`替换为`SESSION_CONFIGS()['dt.args.bizdate']`。
+
+1. 找到连续的两个调度任务，如上文所示 20250101 调度 和 20250102 调度
+
+2. 找到其中变化的部分 如 上文两处标记为黄色的部分
+
+3. 将其替换为 SESSION\_CONFIG()\['dt.args.xx']
+
+   1. 值得重点注意的是，**SESSION_CONFIG()['dt.args.xx'] 返回的结果是string**，如果变量是int需要用SQL进行类型转换，例如 CAST(SESSION_CONFIG()['dt.args.xx'] AS BIGINT)
+   2. 并且设置上刷新的语句
+   3. ```sql
+      CREATE DYNAMIC TABLE target (columns...)
+      PARTITIONED BY (ds)
+      --INSERT OVERWRITE TABLE target (ds='20250101')
+      AS
+      --SELECT *
+      -- 分区列需要出现在最后的schema里，才能保证列的个数是对齐的
+      SELECT t1.id, t1.col1, t2.col1, format(t1.ds) -- YYYY-MM-DD ==> YYYYMMDD
+      FROM 
+          src_1 AS t1 
+      LEFT OUTER JOIN 
+       --   src_2 as t2 WHERE t2.ds = '2025/01/02' AND t2.category = 'A'
+          src_2 as t2 WHERE t2.ds = SESSION_CONFIG()['dt.args.date2'] AND t2.category = 'A'
+      ON t1.id = t2.id;
+      ```
+
+#### 步骤2：调度刷新命令
+
+```SQL
+set dt.args.date1 = {$date1};
+set dt.args.date2 = {$date2};
+REFRESH DYNAMIC TABLE target partition(ds = {$date1});
+```
+
+### 增量任务数据补数和运维
+
+在某些情况下，用户可能需要向已有的分区中补充数据。
+
+#### 方法1：向源表补充数据
+
+用户可以直接向源表中补充数据。这些补充的数据将通过相应的REFRESH任务自动反映到Dynamic Table（DT）中。
+
+**操作步骤**：
+
+1. 直接向源表插入或更新数据。
+2. 执行REFRESH任务，以将更改同步到DT中。
+
+#### 方法2：使用DML语句直接向DT补充数据
+
+用户可直接运用DML语句向DT的指定分区插入数据。**但需注意，若上游数据未发生变动，下一次刷新操作将执行全量刷新，此时数据会恢复至未修改前的状态。**
+
+**操作步骤**：
+
+1. 使用DML语句向DT的特定分区插入数据。
+2. 请注意，直接修改DT将导致下一次该分区的全量刷新。如果用户不希望出现全量刷新的结果，应避免调度该分区的REFRESH任务。
+
+**示例代码**：
+
+```SQL
+set cz.sql.dt.allow.dml=true;
+INSERT INTO DYNAMIC TABLE incremental_dt  VALUES (...);
+```
+
+**注意事项**：
+
+* 直接向DT插入的数据将参与DT的下游计算。如果下游的老分区不需要这些数据，请不要调度涉及这些数据的分区的REFRESH任务。
+* 其他未受影响的分区仍然可以进行增量刷新。
+
+# 场景案例2：基于动态分区的ETL任务优化方案（无维度表或维度表不变）
+
+## 场景特征
+
+1. 动态数据特征：源数据存在历史分区更新可能性
+2. 时间窗口要求：业务需要持续处理N天内可能变更的数据
+3. 维度表情况：维度表不变、无需保留历史维度，或不存在维度表。
+
+## 将离线任务转换为增量任务
+
+```sql
+CREATE TABLE target PARTITIONED BY (ds);
+
+-- 20250101 调度
+SQL :=
+INSERT OVERWRITE TABLE target (ds)
+SELECT * 
+FROM 
+    src_1 AS t1 WHERE t1.ds = '2025-01-01'
+LEFT OUTER JOIN 
+    src_2 as t2 WHERE t2.ds = '2025/01/01' AND t2.category = 'A'
+ON t1.id = t2.id;
+
+-- 20250102 调度
+SQL :=
+INSERT OVERWRITE TABLE target (ds)
+SELECT * 
+FROM 
+    src_1 AS t1 WHERE t1.ds = '2025-01-02'
+LEFT OUTER JOIN 
+    src_2 as t2 WHERE t2.ds = '2025/01/02' AND t2.category = 'A'
+ON t1.id = t2.id;
+```
+
+1. 如果用户原本就是一个依赖调度系统填参数的静态分区调度的作业，不建议改写为动态分区
+2. 如果用户希望 老分区的数据在某个阶段后便不再改变 了，也不建议改写为动态分区
+3. 动态分区改写时，主要遵循的原则是：一切计算都由数据驱动。即每一条数据都应该按照定义好的计算逻辑，和其他数据发生交互，并且写入对应的目标分区中。
+4. 过滤条件中需要根据实际业务需求加个窗口过滤，比如1周/1个月/3个月/一年，防止DT数据持续增加，时间长了之后可能会影响性能。
+
+接下来我们来尝试把上述的静态分区的SQL改写为动态分区
+
+```SQL
+CREATE DYNAMIC TABLE target (COLUMNS...)
+PARTITIONED BY (ds)
+--INSERT OVERWRITE TABLE target (ds)
+SELECT *, DATE_FORMAT(STR_TO_DATE(t1.ds, '%Y-%m-%d'), '%Y%m%d')
+FROM 
+ --   src_1 AS t1 WHERE t1.ds = '2025-01-02'
+    src_1 AS t1
+LEFT OUTER JOIN 
+ --   src_2 as t2 WHERE t2.ds = '2025/01/02' AND t2.category = 'A'
+    src_2 as t2
+ON t1.id = t2.id 
+AND t1.ds = DATE_FORMAT(STR_TO_DATE(t2.ds, '%Y/%m/%d'), '%Y-%m-%d')
+WHERE t2.category = 'A';
+```
+
+## 增量任务数据补数和运维
+
+1. 需要先对源表数据进行补数，如果表是来自于外部数据需要使用数据集成工具重新同步，
+
+2. 历史数据补数：
+
+   1. 影响：补进来的数据会作为增量数据进行加工，这一批次加工会变慢，影响最新数据加工的新鲜度。
+
+   2. 建议：
+
+      1. 建议提前扩大计算资源保证加工性能，补数进行分批操作，减少一次计算的量；
+      2. 另外就是可以补数完，触发一次全量加工
+
+3. 维度表修改：
+
+   1. 影响：维度表修改会直接影响增量计算，如果修改的内容影响加工的范围过大，可能会影响加工性能
+
+   2. 建议：
+
+      1. 如果影响范围小，直接修改即可，增量计算自动识别加工
+      2. 如果影响范围大，可修改完进行一次全量加工
+      3. 如果影响代码逻辑（比如增加列，要加计算逻辑），则需要修改dt逻辑，重新全量计算
+
+# 场景案例3：按天分区任务（需要保留历史维度）
+
+## 业务背景
+
+针对维度表持续变化的按天分区ETL场景，通过构建维度表实时同步体系与动态加工链路，实现事实表与维度表的增量协同计算。改造后可达成：
+
+* 维度数据时效性提升：维度变更延迟从T+1缩短至分钟级
+* 跨表数据一致性保障：建立维度-事实表的版本对齐机制
+* 资源消耗降低：避免维度表全量同步带来的冗余计算
+
+## 场景特征
+
+适用对象需满足：
+
+1. 混合数据处理模式：维度表需支持实时更新+历史版本保留
+2. 版本对齐要求：事实表处理需绑定对应时间点的维度快照
+
+## 将离线任务转换为增量任务
+
+![](.topwrite/assets/image_1747648578327.png)
+
+## 改造实施步骤
+
+### 一、维度表实时化改造
+
+#### 1. 多源同步架构
+
+* **实时同步层**：如果数据来源是外部系统（如MySQL），通过StudioCDC捕获工具实现源库多表实时同步。实时同步要求和源端字段必须保持一致，因此如果维度表含有分区，需要新建一张维度表存储每日维度分区快照。
+
+### 二、加工任务增量改造
+
+* **版本绑定**：事实表的事件时间自动关联对应日的维度分区。
+
+加工任务增量改造示例如下，假设t1是日维度分区表，t2是事实表：
+
+```sql
+CREATE DYNAMIC TABLE target (columns...)
+PARTITIONED BY (ds)
+--INSERT OVERWRITE TABLE target (ds='20250101')
+AS
+SELECT *
+-- 分区列需要出现在最后的schema里，才能保证列的个数是对齐的
+SELECT t1.id, t1.col1, t2.col1, format(t1.ds) -- YYYY-MM-DD ==> YYYYMMDD
+FROM 
+--    src_1 AS t1 WHERE t1.ds = '2025-01-02'
+    src_1 AS t1 WHERE t1.ds = SESSION_CONFIG()['dt.args.date2']
+LEFT OUTER JOIN 
+ --   src_2 as t2 WHERE t2.ds = '2025/01/02' AND t2.category = 'A'
+    src_2 as t2 WHERE t2.ds = SESSION_CONFIG()['dt.args.date3'] AND t2.category = 'A'
+ON t1.id = t2.id;
+```
+
+## 增量任务数据补数和运维
+
+1. **历史数据补数**：通过补数功能按天修改输入表数据，之后按天刷新Dynamic Table即可。增量计算分区表可以按天刷新，不影响当天最新数据的计算。
+
+2. **修改维度表**：
+
+   1. 如果影响范围小，直接修改即可，增量计算自动识别加工
+   2. 如果影响范围大，可修改完进行一次全量加工
+   3. 如果影响代码逻辑（比如增加列，要加计算逻辑），则需要修改dt逻辑，重新全量计算
+
+# 特殊场景下的增量计算效果说明
+
+在以下场景中，增量计算仍然可以正常执行，但性能优化效果可能有限。在最坏情况下，计算性能可能与全量计算相当。建议在这些场景下进行实际测试，评估增量计算的收益后再决定是否采用。
+
+1. **Outer Join 右表频繁变更**：数据查询中包含大量的 Outer Join，且参与 Outer Join 的右表数据处于频繁变更状态，每次变化数据量大于5%。
+2. **大量排序操作**：查询操作里存在大量数据排序需求，例如使用了 Order by 子句。
+3. **Window 函数排序与大分区**：Window 函数需要对数据进行排序（RowNumber=1 的情况除外），并且增量数据中包含多个数据量特别大的 Partition。
+4. **数据聚集性较差**：数据缺乏良好的聚集性，无法通过 Join key、Aggregate key、Window partition key 等清晰地将冷数据和热数据区分开来。

+# 使用DynamicTable开展实时ETL
+
+## 教程概述
+
+通过本教程，您将了解如何使用 Lakehouse 动态表（Dynamic Table）对流式数据进行实时 ETL。
+
+本教程包含以下步骤：
+
+* 环境准备：通过样例数据集获取系统预置的实时数据表
+* 创建 ETL 任务：通过 Dynamic Table 分别构造数据清洗、数据聚合的加工流程
+* 验证加工结果：查看消费层数据表的变化情况，验证实时数据加工结果
+
+## Step 1. 准备工作
+
+本教程将利用 Lakehouse 样例数据集中具备实时数据的表作为数据源表（阿里云上海区域可用），同时创建一个用于测试的计算集群和一个测试用的 schema，用于保存 ETL 过程中产生的数据表。
+
+```sql
+--  1.计算资源和DEMO环境准备
+create vcluster if not exists dt_refresh_vc vcluster_size='XSMALL' vcluster_type='GENERAL';
+
+USE vcluster dt_refresh_vc;
+
+CREATE SCHEMA cz_tutourials;
+use cz_tutourials;
+
+-- 2.查看原始数据：样例数据集ecommerce_events_multicategorystore_live提供实时电商行为样例数据
+select * from clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live
+where event_time between current_timestamp() - INTERVAL 5 minutes and current_timestamp() limit 20;
+```
+
+查看原始数据明细，可以看到表 `ecommerce_events_multicategorystore_live` 持续有实时数据插入。
+![](.topwrite/assets/image_1716287777109.png)
+
+## Step 2.通过定义动态表实现数据清洗
+
+参考如下语句创建动态表 `ecommerce_events_multicategorystore_enriched`。该动态表将每分钟刷新一次，对每分钟的增量数据进行数据清洗转换。为了减少加工数据规模，对历史数据进行过滤，仅处理指定时间之后的新增数据。
+
+刷新任务将根据 DDL 中定义的刷新间隔自动运行，并使用 `refresh_vc` 指定的计算资源执行。
+
+```sql
+
+-- 以当前时间（以当前时间替换下方时间过滤条件，过滤规则可选）作为原始表过滤条件，创建包含数据清洗逻辑的物化视图,配置分钟级别调度
+CREATE DYNAMIC TABLE IF NOT EXISTS ecommerce_events_multicategorystore_enriched
+REFRESH
+    interval '1' minute
+    vcluster dt_refresh_vc
+AS
+SELECT
+event_time,
+CAST(SUBSTRING(event_time,0,19) AS TIMESTAMP) AS event_timestamp, 
+SUBSTRING(event_time,12,2) AS event_hour, 
+SUBSTRING(event_time,15,2) AS event_minute, 
+SUBSTRING(event_time,18,2) AS event_second, 
+event_type,
+product_id, 
+category_id,
+category_code,
+brand,
+CAST(price AS DECIMAL(10,2)) AS price, 
+user_id, 
+user_session,
+CAST(SUBSTRING(event_time,0,19)AS date) AS event_date 
+FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live
+where event_time > TIMESTAMP '2024-05-21 18:18:35.117561';
+refresh DYNAMIC TABLE ecommerce_events_multicategorystore_enriched;
+```
+
+## Step 3.通过定义动态表实现数据聚合分析
+
+根据业务需求，这里模拟对表 `ecommerce_events_multicategorystore_enriched` 进行产品收入、转化率、DAU 等主题的数据聚合加工。
+
+```sql
+-- 分析指标加工
+-- 产品收入分析,配置分钟级别调度
+CREATE DYNAMIC TABLE IF NOT EXISTS Product_Grossing
+REFRESH
+    interval '1' minute
+    vcluster dt_refresh_vc
+AS 
+select event_date,product_id,sum(price) sum_price from ecommerce_events_multicategorystore_enriched
+group by event_date,product_id;
+refresh DYNAMIC TABLE Product_Grossing;
+
+--产品的转化率  Conversion Rates Per Product,配置分钟级别调度
+CREATE DYNAMIC TABLE IF NOT EXISTS Conversion_Rates_Per_Product
+REFRESH
+    interval '1' minute
+    vcluster dt_refresh_vc
+AS
+select event_date,product_id,
+count(case when event_type='purchase' then 1 else null end) num_of_sales,
+count(case when event_type='view' then 1 else null end) num_of_views,
+count(case when event_type='purchase' then 1 else null end)/count(case when event_type='view' then 1 else null end) cvr
+from ecommerce_events_multicategorystore_enriched
+GROUP BY event_date,product_id;
+refresh DYNAMIC TABLE Conversion_Rates_Per_Product;
+--日活跃用户(DAU),配置分钟级别调度
+CREATE DYNAMIC TABLE IF NOT EXISTS DAU
+REFRESH
+    interval '1' minute
+    vcluster dt_refresh_vc
+AS
+select event_date,count(distinct user_id) as DAU from ecommerce_events_multicategorystore_enriched  
+group by event_date;
+refresh DYNAMIC TABLE DAU;
+```
+
+## Step 4.验证实时ETL加工结果
+
+上述动态表在创建后，平台将自动进行调度刷新。当源头表有新数据写入时，最终加工出的聚合表将自动按照聚合逻辑进行更新。
+
+```sql
+-- 查询分析
+-- 当日收入前10产品分析
+select product_id,sum_price as revenue from Product_Grossing where event_date=CURRENT_DATE() order by sum_price desc limit 10;
+-- 当日转化率前10产品分析
+SELECT product_id,cvr FROM Conversion_Rates_Per_Product WHERE event_date=CURRENT_DATE() order by cvr desc limit 10;
+-- 当日DAU
+SELECT EVENT_DATE,DAU FROM DAU WHERE event_date=CURRENT_DATE();
+```
+
+
+

+# UNDROP TABLE 语句
+
+使用 UNDROP TABLE 语句可以恢复被删除的表、动态表和物化视图。是否可以恢复被删除的对象依赖于数据的[保留周期](<TIMETRAVEL.md>)。
+**数据保留周期**：
+对象的历史恢复能力取决于数据的保留周期。当前默认保留周期为1天。您可以通过执行[ALTER命令](TIMETRAVEL.md)来调整保留周期。请注意，修改保留周期可能会增加存储成本。支持表（TABLE）和动态表（DYNAMIC TABLE）不支持物化视图
+
+## 语法
+
+```sql
+UNDROP TABLE tablename;
+```
+
+## 参数说明
+
+- **tablename**：指定被删除的表的名字。支持动态表、内部表、物化视图。
+
+## 示例
+### 示例 1：恢复动态表
+
+```sql
+-- 创建一个基表
+DROP TABLE IF EXISTS dy_base_a;
+CREATE TABLE dy_base_a (i int, j int);
+INSERT INTO dy_base_a VALUES
+(1, 10),
+(2, 20),
+(3, 30),
+(4, 40);
+-- 使用dynamic table进行加工
+DROP DYNAMIC TABLE IF EXISTS change_table;
+CREATE DYNAMIC TABLE change_table
+(i, j)
+AS SELECT * FROM dy_base_a;
+-- 刷新dynamic table
+REFRESH DYNAMIC TABLE change_table;
+-- 查询数据
+SELECT * FROM change_table;
++---+----+
+| i | j  |
++---+----+
+| 1 | 10 |
+| 2 | 20 |
+| 3 | 30 |
+| 4 | 40 |
++---+----+
+DROP DYNAMIC TABLE IF EXISTS change_table;
+UNDROP TABLE change_table;
+SELECT * FROM change_table;
+```
+### 示例 2：删除表后创建同名的表恢复
+
+```sql
+-- 创建表
+CREATE TABLE mytable(id int, name string);
+INSERT INTO mytable VALUES(1, 'aaa');
+-- 删除表
+DROP TABLE mytable;
+-- 查看表删除记录
+SHOW TABLES HISTORY;
+-- 重复建表
+CREATE TABLE mytable(col1 int, col2 string);
+-- 查看表删除记录，未删除的表delete_time是null
+SHOW TABLES HISTORY;

++---------------+------------+-------------------------+----------+------+-------+---------+----------------+-------------------------+
+-- 重命名未删除的表
+ALTER TABLE mytable RENAME TO mytable_back;
+-- 恢复表
+UNDROP TABLE mytable;
+```
+
+## 注意事项
+
+- 请确保在数据保留周期内进行恢复操作，否则无法恢复被删除的表。
+- 在恢复表之前，请确保没有同名的表存在。如有同名表，请先重命名或删除同名表。

+对象的历史恢复能力取决于数据的保留周期。当前预览版本的数据保留周期默认为7天，未来将调整为1天。您可以通过执行[ALTER命令](TIMETRAVEL.md)来调整保留周期。请注意，修改保留周期可能会增加存储成本。支持表（TABLE）、动态表（DYNAMIC TABLE）和物化视图
+
+## 语法
+
+```sql
+UNDROP TABLE tablename;
+```
+
+## 参数说明
+
+* **tablename**：指定被删除的表的名字。支持动态表、内部表、物化视图。
+
+### 示例 1：恢复物化视图
+
+```SQL
+DROP      TABLE mv_base_a;
+
+DROP MATERIALIZED VIEW mv1;
+
+--创建一个基表
+CREATE    TABLE mv_base_a (i int, j int);
+
+INSERT    INTO mv_base_a
+VALUES    (1, 10),
+          (2, 20),
+          (3, 30),
+          (4, 40);
+
+--使用dynamic table进行加工
+CREATE MATERIALIZED VIEW mv1 (i, j) AS
+SELECT    *
+FROM      mv_base_a;
+
+--刷新dynamic table
+REFRESH   MATERIALIZED VIEW mv1;
+
+--查询数据
+SELECT    *
+FROM      mv1;
++---+----+
+| i | j  |
++---+----+
+| 1 | 10 |

++-------------+------------+-------------------------+----------+------+-------+---------+----------------+-------------------------+
+UNDROP TABLE mv1;
+
+SELECT    *
+FROM      mv1;
++---+----+
+| i | j  |
++---+----+
+| 1 | 10 |
+| 2 | 20 |
+| 3 | 30 |
+| 4 | 40 |
++---+----+
+```
+

+## 导出数据到本地
+
+本文档详细介绍了如何将表中数据下载到本地。
+
+目前 Lakehouse 支持两种下载模式：
+
+1. 使用 Lakehouse Studio 的可视化下载界面。
+2. 使用 JDBC 客户端工具，通过 GET 命令下载文件到本地。
+
+## 使用 Lakehouse Studio 的可视化下载界面
+
+在数据开发中，执行 SQL 后，可以将结果下载为 Excel 或 CSV 文件。同时，由于界面显示的结果集限制为 10000 条，如果想下载全部数据，可以点击“下载全部 CSV 文件”，如下图所示：
+
+![](.topwrite/assets/image_1714294896867.png)
+
+## 使用 GET 命令下载数据
+
+1. 前置条件
+
+   * 已安装 [命令行工具](connect-with-cli.md)。
+   * 了解 [GET命令](GET.md) 和 [COPY INTO](COPY_INTO_Location.md) 导出命令。
+
+2. 将表中数据导出到本地
+
+   ```
+    --将数据导出到内部user volume中
+    COPY INTO USER VOLUME  SUBDIRECTORY 'tmp/'  FROM  TABLE mytable file_format = (type = CSV);;
+    
+    -- 查看导出的文件

+## 使用场景
+
+### 场景 1：云器 Lakehouse SQL 数据处理
+
+适用于关系数据库表的批量处理和向量化。
+
+#### 基本索引和下载
+
+```python
+from unstructured_ingest.processes.connectors.sql.clickzetta import (
+    ClickzettaConnectionConfig,
+    ClickzettaIndexer,
+    ClickzettaIndexerConfig,
+    ClickzettaDownloader,
+    ClickzettaDownloaderConfig
+)
+
+# 连接配置
+connection_config = ClickzettaConnectionConfig()
+
+# 索引器配置 - 按批次处理表数据
+indexer = ClickzettaIndexer(
+    connection_config=connection_config,
+    index_config=ClickzettaIndexerConfig(
+        table_name="documents",

+
+适用于文件系统级别的数据处理，支持三种卷类型。
+
+#### Volume 类型说明
+
+1. **User Volume** — 用户个人文件空间
+2. **Table Volume** — 与数据表关联的文件存储
+3. **Named Volume** — 命名的共享文件卷
+
+#### 文件索引和下载
+
+```python
+from unstructured_ingest.processes.connectors.fsspec.clickzetta_volume import (
+    ClickzettaVolumeConnectionConfig,
+    ClickzettaVolumeIndexer,

+    )
+)
+
+# 上传处理后的文件
+local_files = ["/path/to/processed1.json", "/path/to/processed2.json"]
+for local_file in local_files:
+    uploader.upload_file(local_file, "processed/" + os.path.basename(local_file))
+```
+

+## DashScope 嵌入模型详解
+
+### 支持的模型版本
+
+| 模型版本              | 维度   | 最大输入长度      | 适用场景      |
+| ----------------- | ---- | ----------- | --------- |
+| text-embedding-v1 | 1536 | 2048 tokens | 通用文本嵌入    |
+| text-embedding-v2 | 1536 | 2048 tokens | 改进的语义理解   |
+| text-embedding-v3 | 1024 | 8192 tokens | 长文本处理优化   |
+| text-embedding-v4 | 1024 | 8192 tokens | 最新版本，性能最佳 |
+
+#### 嵌入配置示例
+
+```python
+# 不同版本的配置
+configs = {
+    "v1": DashScopeEmbeddingConfig(
+        model_name="text-embedding-v1",
+        batch_size=20,
+        max_retries=3,
+        dimensions=1536
+    ),
+    "v3": DashScopeEmbeddingConfig(
+        model_name="text-embedding-v3",
+        batch_size=25,
+        max_retries=3,
+        dimensions=1024
+    ),
+    "v4": DashScopeEmbeddingConfig(
+        model_name="text-embedding-v4",
+        batch_size=30,
+        max_retries=3,
+        dimensions=1024
+    )
+}
+
+# 选择合适的模型
+embed_config = configs["v4"]  # 推荐使用最新版本
+```
+
+## 最佳实践
+
+### 性能优化
+
+1. **批量处理大小**
+   * SQL 连接器：1000-5000 行/批次
+   * Volume 连接器：100-500 文件/批次
+   * DashScope 嵌入：20-30 文档/批次
+
+2. **内存管理**
+   ```python
+   # 对于大型数据集，使用流式处理
+   for batch in indexer.run():
+       processed = downloader.run(file_data=batch)
+       # 立即处理，避免内存积累
+       process_batch(processed)
+       del processed  # 显式释放内存
+   ```
+
+3. **错误处理**
+   ```python
+   import time
+   from unstructured_ingest.errors_v2 import UserAuthError, UserError
+
+   def robust_processing(files, max_retries=3):
+       for file_data in files:
+           for attempt in range(max_retries):
+               try:
+                   result = process_file(file_data)
+                   break
+               except UserAuthError:
+                   # 认证错误，不重试
+                   raise
+               except UserError as e:
+                   if attempt == max_retries - 1:
+                       raise
+                   time.sleep(2 ** attempt)  # 指数退避
+   ```
+
+### 数据质量保证
+
+1. **输入验证**
+   ```python
+   def validate_input_data(data):
+       required_fields = ['id', 'content']
+       for item in data:
+           if not all(field in item for field in required_fields):
+               raise ValueError(f"缺少必需字段: {required_fields}")
+           if not item['content'].strip():
+               raise ValueError("内容不能为空")
+   ```
+
+2. **输出验证**
+   ```python
+   def validate_embeddings(embeddings, expected_dimension):
+       for i, embedding in enumerate(embeddings):
+           if len(embedding) != expected_dimension:
+               raise ValueError(f"嵌入 {i} 维度错误: {len(embedding)} != {expected_dimension}")
+   ```
+
+### 监控和日志
+
+```python
+import logging
+from unstructured_ingest.logger import logger
+
+# 配置详细日志
+logging.getLogger("unstructured_ingest").setLevel(logging.DEBUG)
+
+# 添加性能监控
+import time
+from contextlib import contextmanager
+
+@contextmanager
+def timer(description):
+    start = time.time()
+    yield
+    elapsed = time.time() - start
+    logger.info(f"{description} 耗时: {elapsed:.2f} 秒")
+
+# 使用示例
+with timer("文档处理"):
+    processed = process_documents(documents)
+```
+
+## 故障排查
+
+### 常见问题
+
+1. **连接失败**
+   ```
+   错误: Failed to create clickzetta session
+   解决: 检查环境变量配置，确保网络连通性
+   ```
+
+2. **嵌入生成失败**
+   ```
+   错误: DashScope API key invalid
+   解决: 验证 DASHSCOPE_API_KEY 环境变量
+   ```
+
+3. **文件下载失败**
+   ```
+   错误: Volume 'xxx' 中未找到匹配的文件
+   解决: 检查 volume 名称和路径是否正确
+   ```
+
+### 调试技巧
+
+1. **启用详细日志**
+   ```python
+   import os
+   os.environ["UNSTRUCTURED_LOG_LEVEL"] = "DEBUG"
+   ```
+
+2. **测试连接**
+   ```python
+   # 测试云器 Lakehouse 连接
+   with ClickzettaConnectionConfig().get_session() as session:
+       result = session.sql("SELECT CURRENT_TIMESTAMP()").collect()
+       print("连接正常")
+
+   # 测试 DashScope
+   from unstructured_ingest.embed.dashscope import DashScopeEmbeddingConfig
+   config = DashScopeEmbeddingConfig(model_name="text-embedding-v3")
+   embeddings = config.embed_documents(["测试文本"])
+   print(f"嵌入维度: {len(embeddings[0])}")
+   ```
+
+3. **验证数据流**
+   ```python
+   # 在每个阶段输出样本数据
+   logger.info(f"索引阶段: 找到 {len(indexed_files)} 个文件")
+   logger.info(f"下载阶段: 处理 {len(downloaded_files)} 个文件")
+   logger.info(f"嵌入阶段: 生成 {len(embeddings)} 个向量")
+   ```

+### Volume 连接器使用示例
+
+#### 完整的 Volume 操作流程
+
+以下示例展示了如何正确使用修复后的 Volume 连接器：
+
+```python
+import tempfile
+from pathlib import Path
+from unstructured_ingest.processes.connectors.fsspec.clickzetta_volume import *
+
+# 1. 创建连接配置
+config = ClickzettaVolumeConnectionConfig(
+    access_config=ClickzettaVolumeAccessConfig()
+)
+
+# 2. 索引操作 - 列出文件
+indexer = ClickzettaVolumeIndexer(
+    connection_config=config,
+    index_config=ClickzettaVolumeIndexerConfig(
+        index_volume_type="user",  # 或 "table", "named"
+        index_volume_name=None,    # table/named volume 需要指定名称
+        index_remote_path="docs/", # 可选：指定子目录
+        index_regexp=r".*\.pdf$"   # 可选：正则过滤
+    )
+)
+files = indexer.list_files()
+
+# 3. 下载操作 - 智能错误处理
+with tempfile.TemporaryDirectory() as temp_dir:
+    downloader = ClickzettaVolumeDownloader(
+        connection_config=config,
+        download_config=ClickzettaVolumeDownloaderConfig(
+            download_volume_type="user",
+            download_dir=temp_dir,
+            # 其他字段会自动继承或推断
+        )
+    )
+    results = downloader.run(files[:3])  # 下载前3个文件
+
+    for result in results:
+        if result["status"] == "success":
+            print(f"下载成功: {result['local_path']}")
+        else:
+            print(f"下载失败: {result['error']}")
+
+# 4. 上传操作 - 自动构建 remote_url
+test_file = Path("test.txt")
+test_file.write_text("测试内容")
+
+uploader = ClickzettaVolumeUploader(
+    connection_config=config,
+    upload_config=ClickzettaVolumeUploaderConfig(
+        volume_type="user",
+        remote_path="uploaded_test.txt"
+        # remote_url 会自动构建
+    )
+)
+uploader.upload_file(str(test_file), "uploaded_test.txt")
+
+# 5. 删除操作 - 彻底删除验证
+deleter = ClickzettaVolumeDeleter(
+    connection_config=config,
+    deleter_config=ClickzettaVolumeDeleterConfig(
+        delete_volume_type="user"
+    )
+)
+success = deleter.delete_file("uploaded_test.txt")
+print(f"删除结果: {success}")
+
+# 6. 验证删除效果
+files_after = indexer.list_files()
+remaining = [f for f in files_after if f["name"] == "uploaded_test.txt"]
+print(f"删除后剩余文件: {len(remaining)}")  # 应该为 0
+```
+
+#### 关键改进说明
+
+1. **配置类字段完整性**: 所有配置类现在包含必要的字段
+2. **路径处理修复**: 修复了字符串和 Path 对象拼接问题
+3. **智能错误处理**: 自动检测和处理 XML 错误响应
+4. **目录vs文件修复**: 正确处理 ClickZetta 创建目录的情况
+5. **删除功能验证**: 确保删除操作的完整性和正确性

+## 使用数据上传功能上传数据
+
+您可以通过云器Lakehouse web界面上的「数据上传」功能向Lakehouse的表中添加数据。
+
+## 使用说明
+
+* 适合较小（不大于2GB）的本地文件（CSV、TXT、Parquet、Avro、ORC）直接上传到云器Lakehouse的表中，无需编程实现，方式最简单。
+* 当前仅支持一次上传一个文件
+* 数据上传功能暂不支持对文件中 struct、map、array 这三种数据类型的字段进行解析。
+
+## 使用数据上传功能
+
+使用数据上传功能时，您可以创建新表，也可以将数据上传到已有表中。
+
+### 将数据上传到新表
+
+在上传数据的时候，您通常可以同时为数据创建一个新表。
+
+#### 前提条件
+
+**您需要具备如下条件才可以使用该功能**
+
+* 您具有如下角色之一：workspace_admin、workspace_dev、workspace_analyst
+* 或者您具有如下权限点：create table、insert + update、delete + insert + update
+
+#### 操作步骤
+
+1. 登录云器Studio账号。
+
+2. 在如下地方均可以点击「上传数据」
+
+   1. 实例首页->数据上传
+   2. 开发->数据树左侧
+   3. 数据资产地图->数据上传
+   4. 数据资产地图->数据管理->数据树->数据上传
+
+      ![](.topwrite/assets/image_1736307100971.png =361)
+
+3. 可将本地文件通过拖拽，或者点击浏览本地系统上的文件的方式添加进来。一次只能添加1个文件，且大小不得超过2GB。
+
+4. Schema：选择目标schema。
+
+5. 选择表：选择「新建表」并在后方输入新建表名。
+
+6. 集群：当前schema所在的工作空间下的可用集群。
+
+7. 数据导入方式：支持追加写入，和先清空后写入两种方式导入数据至新建表中。
+
+8. 信息全部确认后点击“下一步”，系统会基于已上传的文件信息，自动解析出文件中的字段信息。
+
+   ![](.topwrite/assets/image_1736307305607.png =380)
+
+9. 检查并判断自动解析出来的字段名称和字段类型等信息是否符合预期，确认无误后，点击「确认」即可完成新建表并上传数据的操作。
+    * 若发现字段解析有问题，可通过修改**文件属性**配置项，重新刷新获取自动解析后的字段名称、字段类型等信息。或自行修改字段名称或字段类型。
+    * 注意：修改后的字段类型若与系统解析的不匹配，可能导致上传失败。
+
+### 将数据上传到已有表
+
+#### 前提条件
+
+**您需要具备如下条件才可以使用该功能**
+
+* 您具有如下角色之一：workspace_admin、workspace_dev、workspace_analyst
+* 或者您具有如下权限点：create table、insert + update、delete + insert + update
+
+#### 操作步骤

+
+8. 信息全部确认后点击“下一步”。
+
+   ![](.topwrite/assets/image_1736307408590.png =427)
+
+9. 对上传的文件进行相应的解析配置。
+
+   1. 文件类型：系统会基于上传文件的格式后缀自动解析出文件类型，用户也可以自行选择其他文件类型，但是需要确保选择的文件类型与上传的文件实际类型一致。
+
+   2. 文件属性配置：
+
+   3. 表头：
+
+      * 第一行为表头：从文件第一行开始解析，同时将第一行直接解析为「字段名称」并与已有表进行匹配。若有匹配不上的会被判断失败。
+      * 无表头：忽略第一行，从第二行开始作为数值进行读取。
+      * 跳过前N行：自行设置跳过的行数，并从N+1行开始作为数值进行读取。
+
+   4. 字段包裹字符：
+
+      * 双引号：在列分隔符设定下，将双引号 "" 内的内容解析为字段值。**推荐选项**。
+      * 单引号：在列分隔符设定下，将单引号 '' 内的内容解析为字段值。
+      * 空：列分隔符后的所有内容均会被解析为字段值。
+
+   5. 换行符：设定换行符的处理方式，Windows系统为\r\n，Linux、macOS系统为\n。
+
+   6. 空值表示：指定文件中空值的表达方式。
+
+   7. 列分隔符：列之间的分隔符，只允许使用单个字符。对于 CSV 文件，默认为逗号。
+
+   8. 编码方式：UTF-8、GBK
+
+   9. 遇错停止：
+
+      * 立即停止：遇错立刻停止读取，并返回错误提示。
+      * 忽略错误：忽略错误行直到数据全部读取结束，返回错误行信息。
+      * 设置容错行数：当错误行数超过设定值时停止读取，并返回错误提示。

+
+$ cd cz_dbt_project
+```
+
+4. 配置 ClickZetta dbt 项目 profiles
+
+打开并编辑 `~/.dbt/profiles.yml` 文件，增加生产环境配置。参考如下内容，注意 service 中修改为自己所在的 region\_id：
+
+```PowerShell
+cz_dbt_project:
+  target: dev
+  outputs:
+    prod:
+      type: clickzetta
+      service: cn-shanghai-alicloud.api.clickzetta.com
+      instance: <your_instance_name>
+      username: <user_name>
+      password: <passwd>
+      workspace: <your_workspace_name>
+      schema: dbt_prod
+      vcluster: default
+    dev:
+      type: clickzetta
+      service: cn-shanghai-alicloud.api.clickzetta.com
+      instance: <your_instance_name>
+      username: <user_name>
+      password: <passwd>
+      workspace: <your_workspace_name>
+      schema: dbt_dev
+      vcluster: default
+```
+
+5. 验证配置
+
+```PowerShell
+$ dbt debug
+
+02:22:03    Connection test: [OK connection ok]
+
+INFO:stdout_log:02:22:03    Connection test: [OK connection ok]
+
+INFO:file_log:10:22:03.153933 [info ] [MainThread]:   Connection test: [OK connection ok]
+
+02:22:03  All checks passed!
+```
+
+6. 测试运行
+
+通过 `dbt run` 将在目标 dev 环境构建 dbt 项目内置的 2 个测试模型：
+
+* model.cz\_dbt\_project.my\_first\_dbt\_model
+* model.cz\_dbt\_project.my\_second\_dbt\_model
+
+```PowerShell
+$ dbt run
+```
+
+查看执行日志是否成功，并检查目标环境下（例如 `dbt_dev` schema）是否成功创建 `my_first_dbt_model`、`my_second_dbt_model` 数据对象。
+
+# 创建基于Table Stream的增量加工任务
+
+## 场景说明
+
+首先，将外部写入的表定义为 Source Table，并为 Source Table 创建 Table Stream 对象以获取增量变化数据；
+
+其次，在 DBT 中创建使用 Table Stream 的增量模型（"materialized='incremental'"）；
+
+最后，多次运行模型观察增量处理效果。
+
+![](.topwrite/assets/image_1722603029545.png)
+
+## 准备Source表
+
+创建一张原始表，通过数据集成工具持续导入数据：
+
+```SQL
+CREATE TABLE public.ecommerce_events_multicategorystore_live(
+  `event_time` timestamp,
+  `event_type` string,
+  `product_id` string,
+  `category_id` string,
+  `category_code` string,
+  `brand` string,
+  `price` decimal(10,2),
+  `user_id` string,
+  `user_session` string)
+TBLPROPERTIES(
+  'change_tracking'='true');
+```
+
+注意需要在表属性里增加 `'change_tracking' = 'true'` 设置，以开启增量数据捕获能力。
+
+为原始表创建一个Table Stream对象，跟踪原始表的变化记录：
+
+```SQL
+-- Create stream on source table
+CREATE TABLE STREAM public.stream_ecommerce_events 
+on table ecommerce_events_multicategorystore_live
+with PROPERTIES ('TABLE_STREAM_MODE' = 'APPEND_ONLY')
+```
+
+同时在 `cz_dbt_project` 的 models 目录下新建 `sources.yml` 文件，声明已创建的 2 张 source table：
+
+![](.topwrite/assets/image_1722603115937.png)
+
+## 开发模型
+
+创建名称为 events\_enriched.sql 的 dbt 模型，通过配置方式声明为增量模型：
+
+```SQL
+{{
+   config(
+       materialized='incremental'
+   )
+}}
+
+SELECT
+  event_time,
+  CAST(SUBSTRING(event_time,0,19) AS TIMESTAMP) AS event_timestamp, 
+  SUBSTRING(event_time,12,2) AS event_hour, 
+  SUBSTRING(event_time,15,2) AS event_minute, 
+  SUBSTRING(event_time,18,2) AS event_second, 
+  event_type,
+  product_id, 
+  category_id,
+  category_code,
+  brand,
+  CAST(price AS DECIMAL(10,2)) AS price, 
+  user_id, 
+  user_session,
+  CAST(SUBSTRING(event_time,0,19)AS date) AS event_date,
+  CURRENT_TIMESTAMP() as loaded_at
+FROM
+{% if is_incremental() %}
+{{source('quning', 'stream_ecommerce_events')}} 
+{% else %}
+{{source('quning', 'ecommerce_events_multicategorystore_live')}} 
+{% endif %}
+```
+
+注意：
+
+* 当通过 `dbt build` 命令构建模型时，`is_incremental()` 条件判断为 False，将使用原始表 `ecommerce_events_multicategorystore_live` 的全量数据进行模型构建；
+* 当通过 `dbt run` 执行模型时，`is_incremental()` 将识别为 True，将进行增量加工；
+
+如果您希望在构建和后续运行时都仅使用 Table Stream 的增量数据（Table Stream 默认仅提供其创建之后的变化数据）进行模型构建，可对模型进行如下定义：
+
+```Go
+{{
+   config(
+       materialized='incremental'
+   )
+}}
+
+SELECT 
+  `event_time` ,
+  `event_type` ,
+  `product_id` ,
+  `category_id` ,
+  `category_code` ,
+  `brand` ,
+  `price` ,
+  `user_id` ,
+  `user_session` ,
+  CURRENT_TIMESTAMP() as load_time
+  FROM 
+{{source('public', 'stream_ecommerce_events')}}   
+```
+
+## 构建模型
+
+通过 `dbt build` 命令在目标环境创建模型：
+
+```PowerShell
+dbt build --model events_enriched
+```
+
+通过观察日志，模型构建时通过以下语句创建模型，并初始对原始表全量数据进行加工转换：
+
+```SQL
+/* {"app": "dbt", "dbt_version": "1.5.11", "profile_name": "cz_dbt_project", "target_name": "dev", "node_id": "model.cz_dbt_project.events_enriched"} */
+create table dbt_dev.events_enriched
+as
+SELECT
+  event_time,
+  CAST(SUBSTRING(event_time,0,19) AS TIMESTAMP) AS event_timestamp, 
+  SUBSTRING(event_time,12,2) AS event_hour, 
+  SUBSTRING(event_time,15,2) AS event_minute, 
+  SUBSTRING(event_time,18,2) AS event_second, 
+  event_type,
+  product_id, 
+  category_id,
+  category_code,
+  brand,
+  CAST(price AS DECIMAL(10,2)) AS price, 
+  user_id, 
+  user_session,
+  CAST(SUBSTRING(event_time,0,19)AS date) AS event_date,
+  CURRENT_TIMESTAMP() as loaded_at
+FROM
+public.ecommerce_events_multicategorystore_live;

+在 Lakehouse 的目标环境下检查数据对象：

+
+```SQL
+select count(*)  from events_enriched ;
+`count`(*) 
+---------- 
+3700       
+```
+
+数据对象以及初始数据成功创建并写入。
+
+## 运行模型
+
+通过 `dbt run` 命令运行模型：
+
+```PowerShell
+dbt run --model events_enriched
+```
+
+根据 dbt 增量模型逻辑，dbt 将在目标环境创建一个临时视图来表示增量数据。
+
+```SQL
+/* {"app": "dbt", "dbt_version": "1.5.11", "profile_name": "cz_dbt_project", "target_name": "dev", "node_id": "model.cz_dbt_project.events_enriched"} */
+
+create or replace view dbt_dev.events_enriched__dbt_tmp as
+SELECT
+  event_time,
+  CAST(SUBSTRING(event_time,0,19) AS TIMESTAMP) AS event_timestamp, 
+  SUBSTRING(event_time,12,2) AS event_hour, 
+  SUBSTRING(event_time,15,2) AS event_minute, 
+  SUBSTRING(event_time,18,2) AS event_second, 
+  event_type,
+  product_id, 
+  category_id,
+  category_code,
+  brand,
+  CAST(price AS DECIMAL(10,2)) AS price, 
+  user_id, 
+  user_session,
+  CAST(SUBSTRING(event_time,0,19)AS date) AS event_date,
+  CURRENT_TIMESTAMP() as loaded_at
+FROM
+public.stream_ecommerce_events;
+```
+
+同时，dbt 根据模型中 `materialized='incremental'` 的配置，使用 `MERGE INTO` 将 table stream 中的增量数据写入目标模型：
+
+```SQL
+/* {"app": "dbt", "dbt_version": "1.5.11", "profile_name": "cz_dbt_project", "target_name": "dev", "node_id": "model.cz_dbt_project.events_enriched"} */
+
+    -- back compat for old kwarg name
+merge into dbt_dev.events_enriched as DBT_INTERNAL_DEST
+      using dbt_dev.events_enriched__dbt_tmp as DBT_INTERNAL_SOURCE
+      on FALSE
+  when not matched then insert
+     (`event_time`,`event_timestamp`,`event_hour`,`event_minute`,`event_second`,`event_type`,`product_id`,`category_id`,`category_code`,`brand`,`price`,`user_id`,`user_session`,`event_date`,`loaded_at`)
+  values (
+        DBT_INTERNAL_SOURCE.`event_time`,DBT_INTERNAL_SOURCE.`event_timestamp`,DBT_INTERNAL_SOURCE.`event_hour`,DBT_INTERNAL_SOURCE.`event_minute`,DBT_INTERNAL_SOURCE.`event_second`,DBT_INTERNAL_SOURCE.`event_type`,DBT_INTERNAL_SOURCE.`product_id`,DBT_INTERNAL_SOURCE.`category_id`,DBT_INTERNAL_SOURCE.`category_code`,DBT_INTERNAL_SOURCE.`brand`,DBT_INTERNAL_SOURCE.`price`,DBT_INTERNAL_SOURCE.`user_id`,DBT_INTERNAL_SOURCE.`user_session`,DBT_INTERNAL_SOURCE.`event_date`,DBT_INTERNAL_SOURCE.`loaded_at`
+    );
+```
+
+每次执行 dbt run，都会从 table stream 中读取数据并 Merge into 目标模型。写入成功后，Table Stream 的变化记录位置会自动前进，下次 dbt run 时将自动处理最新的增量数据。
+
+# 创建基于动态表的加工任务
+
+## 场景说明
+
+结合前面的场景设计，这里继续使用dbt-clickzetta的Dynamic Table模型对已经完成转换的表进行聚合加工。
+
+首先，在 dbt 中创建使用 Dynamic Table 的模型（`materialized='dynamic_table'`），配置定义 dynamic table 的刷新周期、刷新所使用的计算资源等信息，以便在模型构建后，系统能够根据调度参数自动进行刷新。
+
+其次，在目标环境观察动态表模型的构建和刷新结果。
+

+
+## 开发模型
+
+创建名称为 product\_grossing.sql 的 dynamic table 模型。
+
+* 代码定义
+
+```SQL
+{{
+   config(
+       materialized = 'dynamic_table',
+       vcluster = 'default',
+       refresh_interval = '5 minute'
+   )
+}}
+
+select 
+  event_date,
+  product_id,
+  sum(price) sum_price 
+from 
+  {{ ref("events_enriched")}}
+group by event_date,product_id
+```
+
+## 构建模型
+
+通过 `dbt build` 命令在目标环境创建模型：
+
+```PowerShell
+dbt build --model product_grossing
+```
+
+通过观察日志，模型构建时通过以下语句创建模型，并初始对原始表全量数据进行加工转换：
+
+```SQL
+/* {"app": "dbt", "dbt_version": "1.5.11", "profile_name": "cz_dbt_project", "target_name": "dev", "node_id": "model.cz_dbt_project.product_grossing"} */
+create or replace dynamic table dbt_dev.product_grossing
+refresh interval 5 minute
+vcluster default
+as
+select 
+  event_date,
+  product_id,
+  sum(price) sum_price 
+from 
+  dbt_dev.events_enriched
+group by event_date,product_id;
+```
+
+通过 dbt 可查看模型血缘关系：
+
+![](.topwrite/assets/image_1722603216025.png)
+
+在 Lakehouse 的目标环境下检查数据对象：
+
+```SQL
+show tables;
+

+----------- ------------------------ ------- -------------------- ----------- ---------- 
+dbt_dev     events_enriched          false   false                false       false

+dbt_dev     my_second_dbt_model      true    false                false       false      
+```
+
+同时通过 `DESC` 命令查看动态表的信息，重点确认运行集群、刷新周期参数是否符合预期：
+
+```SQL
+desc extended product_grossing;
+
+column_name                  data_type

+
+Dynamic Table 类型的 dbt 模型，通过构建时设置的周期刷新参数，由 Lakehouse 自动调度，无需通过 `dbt run` 命令执行。
+
+在目标环境完成模型构建后，您可以在 Lakehouse 平台通过以下 SQL 命令查看动态表的刷新状态：
+
+```SQL
+show dynamic table refresh history where name ='product_grossing'
+
+workspace_name schema_name name             virtual_cluster start_time          end_time            duration             state   refresh_trigger  suspended_reason refresh_mode error_message source_tables                                                             stats                                     completion_target job_id

+## 功能
+
+本语句用于切换当前数据库中的 schema，以便用户能够更方便地操作和管理不同 schema 下的数据表。
+
+## 语法
+
+```SQL
+USE [SCHEMA] schema_name;
+```
+
+## 参数说明
+
+1. `SCHEMA`：这是一个可选关键字，您可以使用或省略它。
+2. `schema_name`：指定要切换到的 schema 名称。
+
+## 使用示例
+
+1. 切换到名为 `ods_schema` 的 schema：
+
+   ```SQL
+   USE ods_schema;
+   ```
+
+2. 切换到名为 `reporting_schema` 的 schema，省略 `SCHEMA` 关键字：
+
+   ```SQL
+   USE reporting_schema;
+   ```
+
+3. 切换到名为 `customer_data` 的 schema，并在切换后执行一些查询操作：
+
+   ```SQL
+   USE customer_data;
+   SELECT * FROM customer_orders;
+   SELECT COUNT(*) FROM customer_orders WHERE order_status = 'completed';
+   ```
+
+## 注意事项
+
+- 当您在 SQL 语句中使用 `USE` 切换到某个 schema 后，接下来的查询操作将默认针对该 schema 下的数据表进行。
+- 如果您需要在多个 schema 之间频繁切换，可以在 SQL 语句中多次使用 `USE` 语句。
+- 在使用 `USE` 语句时，请确保指定的 schema 名称在当前数据库中存在，否则将导致错误。

+# 使用 Java SDK 读取 Kafka 数据并实时上传
+
+本文档详细介绍了如何利用 Java SDK 将数据实时写入 Lakehouse，适用于需要实时数据流处理的业务场景，特别适合熟悉 Java 的开发人员。本案例以 Kafka 为数据源，展示如何读取 Kafka 数据并通过 Lakehouse 的 RealtimeStream 接口进行写入。如果您对读取 Kafka 数据没有特殊要求，推荐使用 Lakehouse Studio 数据集成。Lakehouse Studio 数据集成提供了可视化监控，提高了数据管理的透明度。
+
+# 参考文档
+
+[Java SDK实时上传数据](java_reference/realtime-upload.md)
+
+## 应用场景
+
+* 适用于需要实时处理数据流的业务场景。
+* 适合熟悉Java并需要自定义逻辑处理的开发人员。
+
+## 使用限制
+
+* 实时写入的数据可以秒级查询。
+* 表结构变更时，需停止实时写入任务，并在变更后约 90 分钟重新启动。
+* table stream、materialized view 和 dynamic table 只能显示已经提交的数据。实时任务写入的数据需要等待约 1 分钟才能确认，因此 table stream 也需要等待约 1 分钟才能看到。
+
+# 使用案例
+
+本案例使用 Kafka 的 Java 客户端读取数据，并调用 Lakehouse 的 RealtimeStream 接口进行写入。
+
+## 环境准备
+
+* 拥有 Kafka 集群（本次演示使用的是本地搭建的 Kafka），并创建 Topic `lakehouse-stream`。
+
+  * ```SQL
+    bin/kafka-topics.sh --create --topic lakehouse-stream --bootstrap-server localhost:9092
+    ```
+
+* 数据格式为 JSON，使用 Kafka 命令行生产数据：
+
+  * ```SQL
+    {"id": 1, "name": "张三", "email": "zhangsan@example.com", "isActive": true}
+    --kafka生产者命令行
+    bin/kafka-console-producer.sh --topic lakehouse-stream --bootstrap-server localhost:9092
+    ```
+
+* 在 Lakehouse 上创建表
+
+  * ```SQL
+    create table realtime_stream(id int,event json);
+    ```
+
+## 使用Java代码开发
+
+### Maven依赖
+
+在项目的 `pom.xml` 文件中添加以下依赖。Lakehouse Maven 最新依赖可以在 [maven库](https://central.sonatype.com/artifact/com.clickzetta/clickzetta-java) 中找到。
+
+```SQL
+<dependency>
+    <groupId>com.clickzetta</groupId>
+    <artifactId>clickzetta-java</artifactId>
+    <version>1.3.1</version>
+</dependency>
+<!-- https://mvnrepository.com/artifact/org.apache.kafka/kafka-clients -->
+<dependency>
+    <groupId>org.apache.kafka</groupId>
+    <artifactId>kafka-clients</artifactId>
+    <version>3.2.0</version>
+</dependency>
+```
+
+### 编写Java代码
+
+1. **定义 Kafka 连接类**：创建一个 `KafkaReader` 类，配置 Kafka 消费者。
+2. **消费 Kafka 并写入 Lakehouse**：创建 `Kafka2Lakehouse` 类，实现从 Kafka 读取数据并通过 RealtimeStream 写入 Lakehouse 的逻辑。
+
+定义一个 Kafka 连接类，Kafka 的 Java 客户端配置可以参考 [Kafka官网](https://docs.confluent.io/kafka-clients/java/current/overview.html)。
+
+```SQL
+import org.apache.kafka.clients.consumer.ConsumerConfig;
+import org.apache.kafka.clients.consumer.KafkaConsumer;
+import java.util.Collections;
+import java.util.Properties;
+// 创建一个消费者类
+public class KafkaReader {
+    // 定义一个kafka消费者对象
+    private KafkaConsumer<String, String> consumer;
+    // 定义一个构造方法，初始化消费者的配置
+    public KafkaReader() {
+        // 创建一个Properties对象，用于存储消费者的配置信息
+        Properties props = new Properties();
+        // 指定连接的kafka集群的地址
+        props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
+        // 指定消费者所属的消费者组
+        props.put(ConsumerConfig.GROUP_ID_CONFIG, "test-group");
+        // 指定消费者的key和value的反序列化器
+        props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringDeserializer");
+        props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringDeserializer");
+        // 指定消费者的自动位移提交策略
+        props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, "true");
+        // 指定消费者的自动位移提交间隔
+        props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, "1000");
+        // 使用配置信息创建一个kafka消费者对象
+        consumer = new KafkaConsumer<>(props);
+    }
+    // 定义一个方法，用于从指定的主题中读取数据
+    public KafkaConsumer<String, String> readFromTopic(String topic) {
+        consumer.subscribe(Collections.singleton(topic));
+        return consumer;
+    }

+# 使用Java SDK批量上传数据
+
+本文档主要介绍如何使用 Java SDK 的 BulkloadStream 批量将数据加载到 Lakehouse 中。它适合一次性大量数据导入，支持自定义数据源，提供了数据导入的灵活性。本次案例以读取本地文件为例。如果您的数据源在对象存储或 Lakehouse Studio 数据集成支持的范围内，推荐使用 COPY 命令或数据集成功能。
+
+# 参考文档
+
+[Java SDK批量上传数据](java_reference/bulkload-upload.md)
+
+## 应用场景
+
+* 适用于需要批量上传大量数据的业务场景。
+* 适合熟悉Java并需要自定义数据导入逻辑的开发人员。
+
+## 使用限制
+
+* BulkloadStream不支持主键（pk）表的写入。
+* 不适用于时间间隔小于五分钟的频繁数据上传场景。
+
+# 使用案例
+
+本案例以读取本地 CSV 文件为例，使用的数据集是 [巴西电子商务](https://www.kaggle.com/datasets/olistbr/brazilian-ecommerce?select=olist_order_items_dataset.csv) 公共数据集中的 olist_order_items_dataset 数据。若数据源位于对象存储或 Lakehouse Studio 数据集成功能支持的范围，推荐使用 COPY 命令或数据集成功能。
+
+## 前置条件
+
+* 创建表
+  * ```SQL
+    create    table bulk_order_items (
+              order_id STRING,
+              order_item_id INT,
+              product_id STRING,
+              seller_id STRING,
+              shipping_limit_date STRING,
+              price DOUBLE,
+              freight_value DOUBLE
+              );
+    ```
+
+* 对目标表具有INSERT权限。
+
+## 使用Java代码开发
+
+### Maven依赖

+
+Lakehouse 支持 MySQL 客户端与服务端的通讯协议，因此可以使用 MySQL 驱动连接 Lakehouse。然而，Lakehouse 并未实现 MySQL 的语法和数据类型。通过 MySQL 客户端连接 Lakehouse 时，执行的 SQL 语句应使用 Lakehouse 语法，而非 MySQL 语法。例如，`mysqldump` 命令在 Lakehouse 中不可用。
+
+为了适配一些 BI 报表，Lakehouse 实现了一些 MySQL 常用函数，如 `str_to_date` 和 `date_format`。目前，Lakehouse 支持的协议如下：
+MySQL8.x版本客户端连接服务端时默认使用的是caching\_sha2\_password认证方式，有关 MySQL 认证方式的更多信息请参考[官方文档](https://dev.mysql.com/doc/refman/8.0/en/authentication-plugins.html)。连接方式如下，例如连接上海阿里云：
+
+```
+jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com/public
+--添加端口,可选
+jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com:3306/public
+--使用ssl可选
+jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com/public?useSSL=true
+```
+
+MySQL5.x版本客户端连接服务端时默认使用的是mysql\_native\_password认证方式，有关 MySQL 认证方式的更多信息请参考[官方文档](https://dev.mysql.com/doc/refman/8.0/en/authentication-plugins.html)，连接Lakehouse是无需开启SSL，连接方式如下，例如连接上海阿里云：。
+
+* 目前需要重置密码，即使是新建的账号也需要重置密码。这是因为 MySQL 5.x 版本使用的是 `mysql_native_password` 密钥，而 Lakehouse 需要保存 MySQL 的加密算法。目前，只有在修改密码时，Lakehouse 才会保存 MySQL 密钥的加密算法。您可以在修改密码时保持和之前一样，这样可以避免影响其他任务的连接。
+
+```
+jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com/public?useSSL=false
+--添加端口,可选
+jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com:3306/public?useSSL=false
+```
+
+端口：3306（可选）
+
+# 使用场景
+
+* 无法使用Lakehouse驱动场景，比如某些报表场景不支持自定义jdbc驱动或者不支持Lakehoue原生jdbc驱动。如果可以，请尽可能使用 Lakehouse 原生驱动。
+
+# 使用限制
+
+* 目前无法完全兼容MySQL函数和语法，某些报表使用的一些 MySQL 专有语法和函数在发送到 Lakehouse 时会报错（请联系 Lakehouse 支持）。
+* 数据类型限制
+  * 在使用 Lakehouse MySQL 协议时，若 SQL 语句中包含 MySQL 特有的类型（如 mediumint、numeric、bit、time、year、datetime、varbinary、text、blob、enum、set、空间数据类型），系统会报错。例如，“create table mysql\_table(col numeric)” 的建表语句，或 “select cast(xxxx as text)” 这类语句，只要 SQL 中含有上述类型，都会触发报错。为避免此问题，可使用 Lakehouse 的类型替换 MySQL 的数据类型。
+* 语法限制
+  * 不支持MySQL特有语法如MySQL dump命令、Load等命令。
+* 函数限制
+  * Lakehouse 实现了一些 MySQL 常用函数。如果您有需要请联系Lakehouse支持
+* 数据导入限制
+  * 不支持 MySQL 批量导入数据，例如 MySQL 的 LOAD 命令。
+  * 使用MySQL驱动不支持Lakehouse本地命令（[PUT](PUT.md)、[REMOVE](remove-volume.md)、[GET](GET.md)等命令），不支持使用MySQL驱动调用Lakehouse的批量上传和实时上传数据的Java SDK。
+* MySQL列出表结构时需要查询information schema，目前Lakehouse对于新建的表在information schema会存在15分钟延迟，所以新建的表无法立即看到
+
+# 连接方式
+
+## 1.设置计算集群
+
+由于 MySQL 协议中没有传入设置集群的方式，用户可以使用 SQL 命令为用户添加一个默认计算集群。这样在 MySQL 连接时就会使用该集群。需要注意的是，BI场景对分析性能往往有要求，建议为BI工具连接用户选择合适规格的分析型计算集群以提供最佳的查询性能。
+
+```sql
+ALTER USER user_name SET DEFAULT_VCLUSTER = default;
+
+-- 查看集群设置是否生效
+SHOW USERS;
+```
+
+## 2.设置用户名密码
+
+由于 MySQL 协议中没有 workspace 名称和 instance 名称，因此需要将 instance 名称和 workspace 名称拼接到用户名中。
+
+用户名格式要求如下：
+
+```
+登录的账号名称@instance_name.workspace_name
+```
+
+* **instance\_name 获取**：在 [工作空间](workspace-introduction.md)页面 中获取 JDBC 连接串。例如，在 `jdbc:clickzetta://jnsxwfyr.api.clickzetta.com/quick_start?virtualCluster=default` 中，`jnsxwfyr` 为 instance\_name。
+* **workspace\_name 获取**：工作空间的名称。
+
+示例：
+
+```
+user@jnsxwfyr.quick_start
+```
+
+## 3.设置连接地址：
+
+端口：3306
+
+| 云服务商 | 地域 | 连接地址                                               |
+| ---- | -- | -------------------------------------------------- |
+| 阿里云  | 上海 | cn-shanghai-alicloud-mysql.api.clickzetta.com      |
+| 腾讯云  | 上海 | ap-shanghai-tencentcloud-mysql.api.clickzetta.com  |
+|      | 北京 | ap-beijing-tencentcloud-mysql.api.clickzetta.com   |
+|      | 广州 | ap-guangzhou-tencentcloud-mysql.api.clickzetta.com |
+| 亚马逊  | 北京 | cn-north-1-aws-mysql.api.clickzetta.com            |
+
+## 4.其他参数：
+
+* useSSL=true：Lakehouse对于mysql 8.x版本客户端时使用caching\_sha2\_password，因此使用mysql 8.x版本驱动连接时必须设置useSSL=true。如果使用的是mysql5.x版本则useSSL=false即可
+* 数据库名称: Lakehouse的schema名称
+* 端口：3306（可选）
+
+# 一般BI报表配置参数
+
+**连接工具**
+
+建议mysql java 8.0驱动，运行SQL，但是某些报表可能初始化会发一些mysql特有的语法，如果遇到报错请联系Lakehouse技术支持。
+
+**设置vcluster**:
+需要给连接的用户指定默认vcluster，在Lakehouse中指定用户默认vcluster,这样在 MySQL 连接时就会使用该集群。需要注意的是，BI场景对分析性能往往有要求，建议为BI工具连接用户选择合适规格的分析型计算集群以提供最佳的查询性能。
+
+```SQL
+ALTER USER user_name SET DEFAULT_VCLUSTER= default_ap;
+--查看vcluster设置是否生效
+show users;
+```
+
+**驱动要求**：建议mysql8.0以上
+
+**连接地址（必须配置**）
+
+**用户名格式（必须配置**）
+
+* 格式：用户名@instance\_name.worksapace\_name，比如test\@jnsxwfyr.ql\_ws
+
+**数据库名称（必须配置**）
+
+* 格式：schema名称，如public
+
+**端口：3306。某些报表需要配置**
+
+**额外参数（必须配置**）：
+
+如果使用 8.x 驱动，某些报表可以直接在配置参数中输入下面字符串：
+
+* useSSL=true
+
+如果报表中不支持填写参数
+
+* 在报表界面，通常可以找到是否使用 SSL 的选项，需要勾选上。
+  如果使用的是 5.x 版本驱动，则不需要勾选。
+
+# 常见问题
+
+* 无法指定计算资源
+
+  * 需要给连接的用户指定默认vcluster，在Lakehouse中指定用户默认vcluster
+  * ```SQL
+    alter user UAT_TEST set DEFAULT_VCLUSTER= default;
+    --查看vcluster设置是否生效
+    show users;
+    ```
+
+# 问题排查
+
+通过lakehouse作业历史排查问题。如果mysql协议连通之后，mysql连接Lakehouse通常会发一些SQL，作业历史会记录发送的SQL，此时我们可以通过作业历史查看发送的SQL来看错误信息。通过筛选来快速定位，如下三个筛选条件
+
+* 计算集群：bi报表中指定的计算集群
+* 提交人：bi报表中连接的用户名比如是<<<test@jnsxwfyr.ql_ws>>>，则这里筛选为test
+* schema：bi报表中指定的schema名称
+* 通过点击右上角的刷新按钮，来监控 BI 报表发送的 SQL。
+
+![](.topwrite/assets/image_1722596643860.png)
+
+# 案例
+
+* 使用mysql client 连接
+
+mysql client连接Lakehouse：
+
+```
+-- 添加-A选项避免mysql连接时发送一些校验的SQL
+mysql -h cn-shanghai-alicloud-mysql.api.clickzetta.com -u user_name@instance_name.worksapace_name -D  public -p -A
+
+--使用mysql客户端连接报错信息为：ERROR 2059 (HY000): Authentication plugin 'mysql_clear_password' cannot be loaded: plugin not enabled时。可以添加参数使用以下命令来连接
+mysql -h cn-shanghai-alicloud-mysql.api.clickzetta.com -u user_name@instance_name.worksapace_name -Dpublic -p -A --enable-cleartext-plugin  --default-auth=mysql_native_password
+
+
+
+```
+
+* 使用[Power BI连接Lakehouse](PowerBI.md)

+# 使用Python SDK批量上传数据
+
+本文档详细介绍了如何使用Python SDK中的BulkloadStream将数据批量加载到Lakehouse中。这种方法适合一次性大量数据的导入，支持自定义数据源，为数据导入提供了灵活性。本案例以读取本地CSV文件为例，如果数据源位于对象存储或Lakehouse Studio支持的数据集成范围内，推荐使用COPY命令或数据集成功能。
+
+# 参考文档
+
+[Python SDK上传数据](python_reference/bulkload-upload.md)
+
+## 应用场景
+
+* 适用于需要批量上传数据的业务场景。
+* 适合熟悉Python并需要自定义数据导入逻辑的开发人员。
+
+## 使用限制
+
+* BulkloadStream不支持主键（pk）表的写入。
+* 不适用于时间间隔小于五分钟的频繁数据上传场景。
+
+# 使用案例
+
+本案例使用[巴西电子商务](https://www.kaggle.com/datasets/olistbr/brazilian-ecommerce?select=olist_order_items_dataset.csv)公共数据集中的`olist_order_payments_dataset`数据集。
+
+## 前置条件
+
+* 创建目标表`bulk_order_payments`：
+
+```SQL
+
+CREATE TABLE bulk_order_payments (
+          order_id STRING,
+          payment_sequence INT,
+          payment_type STRING,
+          payment_installments INT,
+          payment_value DOUBLE
+          );
+```

+# USE 语句
+
+指定用于当前会话的 SCHEMA 和计算资源。
+
+
+## 语法
+
+```SQL
+-- 切换 schema
+USE [SCHEMA] schema_name;
+-- 切换计算资源
+USE VCLUSTER vc_name;
+```
+
+## 参数说明
+
+1. `SCHEMA`：这是一个可选关键字，可以在语句中省略。
+2. `schema_name`：指定要切换的 schema 名称。
+
+## 使用示例
+
+1. 切换到名为 `ods_schema` 的 schema：
+
+   ```SQL
+   USE ods_schema;
+   -- 查询当前的 SCHEMA
+   SELECT CURRENT_SCHEMA();
+   ```
+
+2. 假设当前工作空间中存在名为 `sample_vc` 的计算集群，您可以使用以下命令切换到该计算集群：
+
+   ```SQL
+   USE VCLUSTER sample_vc;
+   -- 查询当前的计算资源
+   SELECT CURRENT_VCLUSTER();
+   ```
+
+3. 如果您想要切换到名为 `high_performance_vc` 的计算集群，您可以执行以下命令：
+
+   ```SQL
+   USE VCLUSTER high_performance_vc;
+   ```
+
+## 使用注意事项
+
+- 在使用客户端工具（如 [客户端 SQLLine](<connect-with-cli.md>)、[DBeaver](<eco_integration/dbeaver-lakehouse.md>) 等）连接时，相关操作会在整个会话期间生效。
+- 如果您使用 Lakehouse Studio 界面，建议优先通过页面来切换 schema 和计算集群。如果直接使用命令切换，其效果仅临时生效，且需要和要执行的 SQL 语句一起选中执行方可生效。

+# 用户身份
+
+云器采用了灵活的用户及身份管理体系，允许对不同层级、不同类型的用户进行区分和权限控制。
+
+本帮助文档将详细介绍：
+
+* 用户层级：包括全局账号用户和服务实例内用户。
+* 用户类型：包括普通用户和服务用户。
+
+***
+
+## 用户层级
+
+云器中的用户可根据其作用范围划分为两个层级：**全局账号用户** 和 **Lakehouse服务实例内用户**。这两种层级帮助企业在多云多区域的服务实例环境下，既能够全局管理账号下的所有用户，又能够根据服务实例区分不同用户的权限范围。
+
+:-: ![](.topwrite/assets/用户层级.png =740)
+
+^
+
+### 全局用户
+
+全局用户是在云器平台上进行全局管理和配置的用户。每个用户是系统内的一个独立身份，具备独立的用户名和密码。在一个账户中，用户名（user_name）必须唯一，用以区分不同的用户身份。不同用户之间的手机号、邮箱等信息可以重复。
+
+:-: ![](.topwrite/assets/image_1735044530952.png =800)
+
+^
+
+### 服务实例用户
+
+服务实例内用户是在具体的服务实例（instance）范围内的用户。用户只有在服务实例内，才可被授予该服务实例内的各类角色和权限。全局用户会被自动同步至各服务实例，成为服务实例用户。因此服务实例用户的创建、删除和启用状态的管理也都在全局的“用户管理”页面进行。服务实例内的“用户”列表仅提供用户信息查询功能。
+
+服务实例用户默认被授予“instance_user”角色，无任何数据和功能权限。需要进一步被授予实例或工作空间内的权限才可以进行操作。
+
+:-: ![](.topwrite/assets/image_1735044611663.png =800)
+
+***
+
+## 用户类型
+
+Lakehouse 中的用户类型主要分为 **普通用户** 和 **服务用户**：
+
+普通用户通常代表一个企业内的实际人员，在系统中进行日常的数据查询、分析、管理等操作；
+
+服务用户是为了满足自动化流程或系统级操作需求而创建的特殊类型用户。服务用户**不允许**在Web端登录，但可使用JDBC连接或被配置于调度任务中，用于调度任务、程序对Lakehouse进行自动化或系统级的调用。
+
+在Lakehouse中，服务用户包含**系统服务用户** 和 **自定义服务用户**：
+
+其中，**系统服务用户**是Lakehouse在账户初始化时默认创建的，用于访问服务实例内的资源以实现部分系统功能的用户身份；
+
+**自定义服务用户**是用户可自助创建的，用于用户自身业务应用使用的身份。
+
+Lakehouse内的系统服务用户默认为禁用状态。仅当用户使用的功能涉及系统服务用户时，系统才会提示用户“启用”，包括：
+
+sysservice_clickzetta —— 在SYS工作空间中操作临时系统资源和系统数据。
+
+sysservice_auto_mv —— 启用auto_mv时开启，用于读取job_history并管理auto_mv使用的临时mv。

+# Lakehouse用户授权入门指导
+
+## 1. 引言
+
+云器Lakehouse采用了灵活且强大的权限管理体系，通过基于角色的访问控制（RBAC）实现细粒度的数据访问管理。本指南将结合理论知识和实际操作，详细介绍Lakehouse的用户授权管理流程，帮助管理员高效管理数据资源访问权限。
+
+本指南也通过一个实际实验来验证这个过程。
+
+^
+
+:-: ![](.topwrite/assets/image_1747735632210.png =796)
+
+^
+
+## 2. 用户管理体系架构
+
+### 2.1 用户层级关系
+
+云器Lakehouse的用户管理体系分为两个层级：
+
+* **全局用户**：在云器平台上全局管理的用户，每个用户拥有独立的身份，具备唯一用户名和密码。
+* **工作空间用户**：在特定Lakehouse服务实例中的特定工作空间里的用户，仅在工作空间内内可被授予相应角色和权限。
+
+> **重要概念**：全局用户会自动同步至各服务实例，成为服务实例用户，为所有空间供应用户身份，但是需要进一步在空间内授权。因此，当我们在工作空间内通过SQL创建用户时，本质上是将已存在于服务实例中的用户添加到当前工作空间，是一种工作空间级别的授权操作，而非真正意义上的用户创建。这就是为什么在工作空间内使用SQL创建用户时不需要指定密码。
+
+### 2.2 用户类型
+
+* **普通用户**：代表企业内实际人员，用于日常的数据查询、分析和管理操作。
+* **服务用户**：满足自动化流程或系统级别操作的特殊用户，不允许Web登录，但可用于JDBC连接或调度任务。
+
+## 3. 角色管理基础
+
+### 3.1 角色定义与类型
+
+角色是一种授权管理工具，将多个权限点集中在一起，再授予给一个或多个用户。Lakehouse中的角色分为两种类型：
+
+* **预置角色**：系统自动配置的角色，不可删除，可以修改权限\*，可直接授予给用户。
+* **自定义角色**：用户根据业务需求创建的角色，可灵活配置与维护权限。
+
+\*说明：预置角色中，工作空间管理员（workspace\_admin）和实例管理员（instance\_admin）不允许修改权限。其他预置角色可以修改权限。
+
+### 3.2 角色级别
+
+* **实例角色（Instance Role**）：用于实例级资源和操作的全局管控，或跨多个工作空间的权限授予。
+* **工作空间角色（Workspace Role**）：作用于特定工作空间内的对象，如schema、table、virtual cluster等。
+
+## 4. 实际操作步骤
+
+### 4.1 用户管理操作
+
+**1. 在工作空间中添加用户**
+
+```sql
+-- 将已存在于服务实例的用户添加到当前工作空间
+CREATE USER username;
+```
+
+**2. 查看工作空间内的用户**
+
+```sql
+-- 显示当前工作空间内的所有用户
+SHOW USERS;
+```
+
+**3. 删除工作空间内的用户**
+
+```sql
+-- 从当前工作空间移除用户（不影响服务实例中的用户）
+DROP USER username;
+```
+
+### 4.2 角色管理操作
+
+**1. 创建自定义角色**
+
+```sql
+-- 创建工作空间级别的自定义角色
+CREATE ROLE role_name;
+```
+
+**2**. **查看角色**
+
+```sql
+-- 查看当前工作空间内的所有角色
+SHOW ROLES;
+```
+
+**3. 删除角色**
+
+```sql
+-- 删除自定义角色
+DROP ROLE role_name;
+```
+
+### 4.3 权限授予操作
+
+**1. 授予Schema级别权限**
+
+```sql
+-- 授予角色在Schema上创建表和视图的权限
+GRANT CREATE TABLE, CREATE VIEW ON SCHEMA schema_name TO ROLE role_name;
+```
+
+**2. 授予表级别权限**
+
+```sql
+-- 授予角色对表的查询、修改等权限
+GRANT SELECT, INSERT, UPDATE, DELETE, ALTER ON TABLE schema_name.table_name TO ROLE role_name;
+```
+
+**3. 授予视图权限**
+
+```sql
+-- 授予角色对视图的查询权限
+GRANT SELECT VIEW schema_name.view_name TO ROLE role_name;
+```
+
+**4. 将角色授予用户**
+
+```sql
+-- 将角色授予给用户
+GRANT ROLE role_name TO USER username;
+```
+
+### 4.4 权限撤销操作
+
+**1. 撤销对象权限**
+
+```sql
+-- 撤销表的SELECT权限
+REVOKE SELECT ON TABLE schema_name.table_name FROM ROLE role_name;
+```
+
+**2. 撤销用户角色**
+
+```sql
+-- 从用户撤销角色
+REVOKE ROLE role_name FROM USER username;
+```
+
+## 5. 权限验证与审计
+
+### 5.1 查询用户权限
+
+```sql
+-- 查看用户被授予的角色和权限
+SHOW GRANTS TO USER username;
+```
+
+### 5.2 查询角色权限
+
+```sql
+-- 查看角色被授予的具体权限
+SHOW GRANTS TO ROLE role_name;
+```
+
+### 5.3 查询对象权限被授出的权限
+
+```sql
+-- 查看表被授出的具体权限及授出给哪个角色/用户
+SHOW GRANTS ON table schema_name.table_name;
+```
+
+### 5.3 查询当前用户
+
+```sql
+-- 获取当前登录用户
+SELECT CURRENT_USER();
+```
+
+##
+
+## 6. 完整实验案例
+
+以下是一个完整的用户授权管理实践案例，从创建用户到清理环境的全流程：
+
+### 6.1 创建测试用户
+
+```sql
+-- 创建测试用户（将服务实例用户添加到工作空间）
+CREATE USER test01;
+CREATE USER test02;
+
+-- 验证用户创建是否成功
+SHOW USERS;
+```
+
+### 6.2 创建测试环境
+
+```sql
+-- 创建测试Schema和表
+CREATE SCHEMA IF NOT EXISTS permission_test_schema;
+
+CREATE TABLE IF NOT EXISTS permission_test_schema.permission_test_sales_data (
+    id INT,
+    product_name VARCHAR(100),
+    sale_date DATE,
+    amount DECIMAL(10,2)
+);
+
+-- 插入测试数据
+INSERT INTO permission_test_schema.permission_test_sales_data VALUES 
+    (1, 'Product A', date '2025-01-15', 1500.00),
+    (2, 'Product B', date '2025-01-20', 2300.50),
+    (3, 'Product C', date '2025-02-05', 800.75);
+```
+
+### 6.3 创建和授权角色
+
+```sql
+-- 创建角色
+CREATE ROLE permission_test_developer_role;
+CREATE ROLE permission_test_analyst_role;
+
+-- 配置角色权限
+-- 授予开发者角色更多权限
+GRANT CREATE TABLE, CREATE VIEW ON SCHEMA permission_test_schema TO ROLE permission_test_developer_role;
+GRANT SELECT, INSERT, UPDATE, DELETE, ALTER ON TABLE permission_test_schema.permission_test_sales_data TO ROLE permission_test_developer_role;
+
+-- 授予分析师角色只读权限
+GRANT SELECT ON TABLE permission_test_schema.permission_test_sales_data TO ROLE permission_test_analyst_role;
+
+-- 将角色授予用户
+GRANT ROLE permission_test_developer_role TO USER test01;
+GRANT ROLE permission_test_analyst_role TO USER test02;
+```
+
+### 6.4 验证权限配置
+
+```sql
+-- 查看用户权限
+SHOW GRANTS TO USER test01;
+SHOW GRANTS TO USER test02;
+
+-- 查看角色权限
+SHOW GRANTS TO ROLE permission_test_developer_role;
+SHOW GRANTS TO ROLE permission_test_analyst_role;
+```
+
+### 6.5 环境清理
+
+```sql
+-- 撤销角色权限
+REVOKE ROLE permission_test_developer_role FROM USER test01;
+REVOKE ROLE permission_test_analyst_role FROM USER test02;
+
+-- 删除视图和表
+DROP VIEW IF EXISTS permission_test_schema.permission_test_sales_view;
+DROP TABLE IF EXISTS permission_test_schema.permission_test_sales_data;
+
+-- 删除角色
+DROP ROLE permission_test_developer_role;
+DROP ROLE permission_test_analyst_role;
+
+-- 删除Schema
+DROP SCHEMA IF EXISTS permission_test_schema;
+
+-- 移除用户
+DROP USER test01;
+DROP USER test02;
+
+-- 验证用户是否已移除
+SHOW USERS;
+```
+
+## 7. 最佳实践与注意事项
+
+### 7.1 用户管理最佳实践
+
+* **理解用户层级**：区分全局账号用户和服务实例用户，明确`CREATE USER`在工作空间中的实际作用。
+* **用户创建前检查**：使用`SHOW USERS`确认用户是否已存在于工作空间中，避免冗余操作。
+* **服务用户规范命名**：对于自动化流程的服务用户，建议以特定前缀命名，如`svc_`，以便区分。
+
+### 7.2 角色管理最佳实践
+
+* **遵循最小权限原则**：角色权限设计应遵循最小权限原则，只授予必要的权限。
+* **角色层次设计**：设计层次化的角色结构，便于权限管理和维护。
+* **角色命名规范**：采用规范的命名约定，如`[业务域]_[功能]_role`格式。
+
+### 7.3 权限审计与维护
+
+* **定期审计**：定期审查用户权限和角色分配，确保符合安全要求。
+* **权限变更记录**：记录重要的权限变更操作，便于追溯。
+* **测试验证**：权限变更后，使用相关用户身份测试验证权限是否正确生效。
+
+## 8. 常见问题与解答
+
+**Q1: 为什么在工作空间中创建用户时不需要指定密码**？
+
+A1: 这是因为`CREATE USER`命令在工作空间中执行时，实际上是将已存在于服务实例中的用户添加到当前工作空间，是一种授权操作，而非真正创建新用户。用户的身份验证信息（如密码）是在全局账号层面管理的。
+
+**Q2: 用户在一个工作空间被删除后，是否影响其在其他工作空间的访问**？
+
+A2: 不影响。`DROP USER`命令只是将用户从当前工作空间移除，不影响用户在其他工作空间的权限和访问，也不会删除服务实例中的用户信息。
+
+**Q3: 如何查看某个具体对象（如表）的所有授权情况**？
+
+A3: 通过show grants on <对象名称>的语句查看。也可以通过查询information schema查看。
+
+**Q4: 预置角色和自定义角色有什么区别**？
+
+A4: 预置角色是系统自动配置的，不可删除，适合常见场景；自定义角色由用户创建，可灵活配置权限，适合特定业务需求。
+
+**Q5: 一个用户可以同时拥有多个角色吗**？
+
+A5: 可以。用户可以被授予多个角色，将获得这些角色的所有权限的并集。
+
+## 9. 总结

+# 使用 ClickZetta MCP + Claude 进行数据运维问题排查
+
+## 问题背景
+
+某天下午，突然收到短信告警：**周期调度的数据更新任务失败**。
+
+作为值班 DBA，立即登录 ClickZetta Lakehouse，初步排查后发现：
+
+* 物化视图 `daily_summary_mv` 从当天 10 点后没有新数据；
+* 手动 刷新该物化视图可以刷新成功，但数据并没有更新；
+* 上游源表确认有最新数据。
+
+问题很棘手：源表有数据，MV 却刷不出来，而这个 MV 的 SQL 定义超过 200 行，涉及多个 CTE 和复杂的 JOIN 逻辑。
+
+**传统做法**：逐行阅读 MV 定义 → 手写诊断 SQL → 逐层排查 → 可能花费数小时。
+
+**MCP + Claude 做法**：描述问题，使用 ClickZetta MCP + Claude 帮助分析，数分钟后即得到了准确的问题根因，并进一步获得了修复建议。
+
+***
+
+## 第一步：切换环境（30秒）
+
+### 👤 提示词
+
+使用提示词，切换到发生问题的环境：
+
+```
+使用 ClickZetta MCP 工具，切换到腾讯云上海环境
+```
+
+### 🤖 Claude 响应
+
+```
+✅ 已成功切换到腾讯云上海环境！
+
+当前连接信息：
+| 配置项 | 值 |
+|--------|-----|
+| 服务端点 | ap-shanghai-tencentcloud.api.clickzetta.com |
+| 实例ID | 158026 |
+| Workspace | data_warehouse |
+| Schema | public |
+```
+
+> 💡 **技巧**：ClickZetta MCP 支持配置多个云环境，在配置好连接环境后，用自然语言即可快速切换，无需记忆连接参数。
+
+***
+
+## 第二步：描述问题，让 AI 自动诊断（3分钟）
+
+### 👤 提示词
+
+```
+帮我分析以下问题的原因：
+
+我收到系统监控报警，report_schema.daily_summary_mv 从 12 月 13 日下午开始没有数据。
+
+我执行 SELECT bill_hour, COUNT(1) FROM report_schema.daily_summary_mv 
+WHERE bill_date = '20251213' GROUP BY bill_hour; 
+发现从 10 点以后就没有数据了。
+
+但是源表 raw_schema.event_details 是有数据的。
+
+执行 REFRESH MATERIALIZED VIEW 刷新后，仍没有 10 点以后的数据。
+
+查询并分析造成这一问题的原因。
+```
+
+> 💡 **提问技巧**：描述问题时包含以下要素效果最佳，描述得越具体、准确，越能提高排查效率且避免模型产生幻觉：
+>
+> * 📌 **现象**：什么数据没有了
+> * 📌 **时间点**：从什么时候开始
+> * 📌 **已尝试的操作**：做过什么排查
+> * 📌 **矛盾点**：源表有数据但 MV 没有
+
+### 🤖 Claude 自动诊断过程
+
+Claude 收到问题后，自动规划并执行了以下诊断步骤：
+
+***
+
+#### 诊断步骤 1：获取 MV 定义，理解数据逻辑
+
+```sql
+-- Claude 自动执行
+DESC TABLE EXTENDED report_schema.daily_summary_mv
+```
+
+Claude 从返回的 `view_text` 中识别出关键逻辑：
+
+```
+📍 发现关键线索！
+
+物化视图中有一个 MaxDateHour 的边界控制逻辑，它取两个数据源的最小值作为边界：
+
+WITH MaxDateHour AS (
+    SELECT MIN(max_ts) AS max_ts    -- ⚠️ 取最小值！
+    FROM (
+        -- 第一路数据
+        SELECT MAX(CONCAT(ds, '-', hh)) AS max_ts
+        FROM event_details WHERE event_type = 'type_a'
+        UNION ALL
+        -- 第二路数据  
+        SELECT MAX(CONCAT(ds, '-', hh)) AS max_ts
+        FROM metrics_data
+    ) t1
+)
+```
+
+***
+
+#### 诊断步骤 2：检查边界值
+
+```sql
+-- Claude 自动执行
+SELECT MIN(max_ts) AS current_boundary
+FROM (
+    SELECT MAX(CONCAT(ds, '-', hh)) AS max_ts
+    FROM raw_schema.event_details WHERE event_type = 'type_a'
+    UNION ALL
+    SELECT MAX(CONCAT(ds, '-', hh)) AS max_ts
+    FROM raw_schema.metrics_data
+) t1
+```
+
+**结果**：
+
+```
+| current_boundary |
+|------------------|
+| 20251213-10      |
+```
+
+```
+✅ 找到问题了！MaxDateHour 边界是 20251213-10，正好对应数据截止时间。
+```
+
+***
+
+#### 诊断步骤 3：定位是哪个数据源落后
+
+```sql
+-- Claude 自动执行：分别检查两个数据源
+SELECT 'source_a (type_a only)' AS source, MAX(CONCAT(ds, '-', hh)) AS max_ts
+FROM raw_schema.event_details WHERE event_type = 'type_a'
+UNION ALL
+SELECT 'source_a (all types)' AS source, MAX(CONCAT(ds, '-', hh)) AS max_ts
+FROM raw_schema.event_details WHERE event_type IN ('type_a', 'type_b', 'type_c')
+UNION ALL
+SELECT 'source_b' AS source, MAX(CONCAT(ds, '-', hh)) AS max_ts
+FROM raw_schema.metrics_data
+ORDER BY source
+```
+
+**结果**：
+
+```
+| source                  | max_ts       |
+|-------------------------|--------------|
+| source_a (type_a only)  | 20251213-10  |  ⬅️ 瓶颈在这里！
+| source_a (all types)    | 20251213-18  |
+| source_b                | 20251213-16  |
+```
+
+***
+
+#### 诊断步骤 4：确认数据特征
+
+```sql
+-- Claude 自动执行：查看各类型的数据分布
+SELECT event_type, MAX(hh) as max_hour, COUNT(1) as record_count
+FROM raw_schema.event_details 
+WHERE ds = '20251213' AND event_type IN ('type_a', 'type_b', 'type_c')
+GROUP BY event_type
+ORDER BY event_type
+```
+
+**结果**：
+
+```
+| event_type | max_hour | record_count |
+|------------|----------|--------------|
+| type_a     | 10       | 300          |  ⬅️ 事件驱动，数据稀疏
+| type_b     | 18       | 7,070        |
+| type_c     | 18       | 22,215       |
+```
+
+***
+
+### 🤖 Claude 输出：根因分析报告
+
+Claude通过实际在Lakehouse中执行查询和对返回数据的分析，很快得到了问题根因：
+
+MV 定义中使用 MIN() 取多个数据源的最小边界值。
+type\_a 是事件驱动型数据，只有用户执行特定操作时才产生记录。
+12月13日10点后没有相关操作，导致该类型数据"停滞"，卡住了整个 MV。
+
+以下是Claude的完整回复：
+
+```
+🔍 问题根因分析报告
+
+问题定位
+物化视图的数据被 MaxDateHour 边界条件限制在了 2025年12月13日10点。
+
+数据验证
+| 数据源 | 最新数据时间 | 说明 |
+|--------|-------------|------|
+| event_details (type_a) | 20251213-10 | ⚠️ 瓶颈源 |
+| event_details (全部类型) | 20251213-18 | 正常 |
+| metrics_data | 20251213-16 | 正常 |
+
+根本原因
+MV 定义中使用 MIN() 取多个数据源的最小边界值。
+type_a 是事件驱动型数据，只有用户执行特定操作时才产生记录。
+12月13日10点后没有相关操作，导致该类型数据"停滞"，卡住了整个 MV。
+
+影响链路
+type_a 数据停在 10 点
+    ↓
+MaxDateHour = MIN(10, 16) = 10
+    ↓
+WHERE 条件过滤掉 > 10 点的所有数据
+    ↓
+type_b、type_c 的新数据也被排除
+    ↓
+物化视图无新数据
+
+建议方案
+修改 MaxDateHour 计算逻辑，将边界条件从仅 type_a 改为包含所有相关类型...
+```
+
+***
+
+## 第三步：根据业务需求，迭代优化方案（2分钟）
+
+Claude 给出的初步方案是直接修改边界逻辑。根据经验，对已有 MV DDL 中边界条件的修改很可能在重建后影响过去的历史数据。这在要求历史数据不许变更的业务中是不可接受的。
+
+因此，在提示词中追加了以下约束，要求在满足要求的前提下提供更好的解决方案：
+
+### 👤 提示词
+
+```
+采用这种方案：修改 MaxDateHour 的计算逻辑，将边界条件从仅 type_a 改为包含所有类型。
+
+但由于这是一个 MV，改变 DDL 重新刷新后会改变所有过去的数据，造成历史数据和已处理记录不一致。
+
+所以这里的修改希望能够兼容历史数据，加上从 2025年12月13日20点之后，
+才使用新的边界计算方式。应该怎么处理？
+```
+
+> 💡 **迭代技巧**：AI 给出的初步方案可能不完全符合业务需求。业务需求的背景知识并不存在于 AI 这次对话的上下文中，所以必须由人来充分考虑，并将这种业务约束补充给 AI。在使用 AI 来协助运维和解决问题时，不能放弃思考，无脑遵循 AI 给出的建议来执行。尤其需要提供的是“为什么有这个约束”，这样更能发挥 AI 的思考、推理能力。
+>
+> 通过追加约束条件，让 AI 生成更精准的方案：
+>
+> * 📌 **明确约束**：不能影响历史数据
+> * 📌 **给出边界**：从什么时间点开始生效
+> * 📌 **说明原因**：为什么有这个约束
+
+### 🤖 Claude 输出：兼容性改造方案
+
+Claude 理解了业务约束后，设计了一个向后兼容的方案：
+
+```
+设计思路
+
+需要修改 MaxDateHour 的逻辑，使其：
+- 2025年12月13日20点之前：继续使用原来的 type_a 边界（保护历史数据）
+- 2025年12月13日20点及之后：使用新的全类型边界
+
+兼容性改造 SQL
+
+WITH MaxDateHour AS (
+    SELECT 
+        SPLIT(t2.max_ts, '-')[0] AS max_ds,
+        SPLIT(t2.max_ts, '-')[1] AS max_hh,
+        t2.max_ts
+    FROM (
+        SELECT MIN(max_ts) AS max_ts
+        FROM (
+            -- 数据源 A（兼容历史逻辑）
+            SELECT GREATEST(
+                -- 原逻辑：只用 type_a（保护历史数据）
+                (SELECT COALESCE(MAX(CONCAT(ds, '-', hh)), '19700101-00') 
+                 FROM raw_schema.event_details 
+                 WHERE event_type = 'type_a'),
+                 
+                -- 新逻辑：全类型边界，仅在 >= 切换时间点后生效
+                (SELECT CASE 
+                    WHEN MAX(CONCAT(ds, '-', hh)) >= '20251213-20' 
+                    THEN MAX(CONCAT(ds, '-', hh)) 
+                    ELSE '19700101-00' 
+                 END
+                 FROM raw_schema.event_details 
+                 WHERE event_type IN ('type_a', 'type_b', 'type_c'))
+            ) AS max_ts
+            
+            UNION ALL
+            
+            -- 数据源 B（保持不变）
+            SELECT MAX(CONCAT(ds, '-', hh)) AS max_ts
+            FROM raw_schema.metrics_data
+        ) t1
+    ) t2
+)
+
+逻辑说明
+
+| 场景 | type_a 边界 | 全类型边界 | GREATEST 结果 | 效果 |
+|------|-------------|------------|---------------|------|
+| 历史数据 (< 切换点) | 20251213-10 | 返回最小值 | 20251213-10 | ✅ 保持原逻辑 |
+| 新数据 (≥ 切换点) | 20251213-10 | 20251213-18 | 20251213-18 | ✅ 使用新逻辑 |
+```
+
+***
+
+## 第四步：根据Claude建议的方案，对线上逻辑进行修复（2分钟）
+
+在这个案例中，直接按照上述逻辑在线上环境中手动更新了MV的DDL，重建MV后，成功修复了线上问题。
+
+其实也可以直接要求 Claude 根据上述方案操作修改该 MV 进行修复，现有工具能力完全可以实现。但考虑到线上环境较为复杂，为了避免大模型幻觉造成操作失误并引发其他问题，个人对于线上数据和表的修改、写入、重建等操作，还是倾向于采用更稳妥的人工执行方式。
+
+还有一种方式是让 Claude 根据上述方案创建一个临时视图，然后自动比对两个视图的数据，验证无误后，再更新原 MV 的 DDL。这样会更加稳妥。这个案例中的问题比较直白，为了快速修复，就省去了这一步骤。

+## 功能
+
+`uuid()` 函数用于生成一个全局唯一标识符（UUID），该标识符是一个符合通行标准的、长度为 36 个字符的字符串。UUID 是一种广泛应用于分布式系统的标识方法，可以保证在不同系统、不同时间生成的 UUID 值是唯一的。
+
+## 语法
+
+```
+uuid()
+```
+
+## 返回值
+
+该函数返回一个字符串类型的 UUID，格式为 `8-4-4-4-12`，例如：`123e4567-e89b-12d3-a456-426614174000`。
+
+## 使用示例
+
+以下是一些使用 `uuid()` 函数的示例：
+
+1. 生成一个 UUID 并将其作为新记录的 ID：
+
+   ```SQL
+   INSERT INTO users (id, username, email) VALUES (uuid(), 'john_doe', 'john@example.com');
+   ```
+
+2. 在查询中使用 UUID 作为某个唯一标识：
+
+   ```SQL
+   SELECT * FROM products WHERE id = 'a1b2c3d4-5678-90ab-cdef-1234567890ab';
+   ```
+
+3. 为每个订单生成一个唯一的追踪码：
+
+   ```SQL
+   UPDATE orders SET tracking_number = uuid() WHERE status = 'pending';
+   ```
+
+4. 在创建新的日志记录时，使用 UUID 作为日志的唯一标识：
+
+   ```SQL
+   INSERT INTO logs (log_id, user_id, action, timestamp) VALUES (uuid(), 123, 'login', NOW());
+   ```
+
+## 注意事项
+
+- UUID 值的生成依赖于特定的算法，因此不同的数据库系统可能会生成不同格式的 UUID。
+- 在使用 UUID 作为数据库表的主键时，需要注意其性能影响，因为 UUID 的生成通常是随机的，可能会导致数据在存储（如索引）上分布不均。
+- UUID 虽然具有极高的唯一性，但在某些场景下，例如需要有序处理的业务逻辑中，可能不适用。

+# 计算集群缓存
+
+Lakehouse使用缓存技术来加速查询性能和效率。平台提供了三种类型的Cache来提高查询性能
+
+1.查询结果缓存(ResultCache)
+
+2.元数据缓存(MetadataCache)
+
+3.计算集群本地缓存 (Virtual Cluster Local Disk Cache)
+
+![](.topwrite/assets/image_1729739810389.png)
+
+其中:
+
+元数据缓存和查询结果缓存服务从属于服务层,可在工作空间内共享。
+
+计算集群缓存本地缓存保存在集群本地节点,仅在使用指定虚拟集群时可以使用其本地缓存。
+
+在 Lakehouse 的存算分离架构中，数据存储在对象存储上。为了应对网络请求延迟并提升分析场景的响应速度，我们采用了缓存策略。计算集群缓存将频繁访问的数据存储在本地节点，从而加速查询。
+
+计算集群缓存分为两种：
+
+1. **主动缓存**：通过命令手动将表缓存到计算集群。每次计算集群启动时，会自动加载这些预缓存的表最新写入的数据或者分区。目前仅支持 AP 型集群。适用场景如 BI 报表查询，可以显著减少查询延迟，提高数据处理速度。
+2. **被动缓存**：在首次查询时，Lakehouse 自动将读取的文件缓存到计算集群。后续包含相同表文件的查询将直接利用缓存，加速查询过程。支持 GP 型和 AP 型集群。第二次及以后的查询，如果涉及到首次缓存的表，将直接命中缓存。
+
+## 使用方式
+
+1. **主动缓存表方式**：
+
+```SQL
+ALTER VCLUSTER default SET PRELOAD_TABLES="schema1.table1,schema2.table2";
+```
+
+如果需要添加新表到缓存,需要将已添加的表都带上否则会将原来的覆盖：
+
+```SQL
+ALTER VCLUSTER default SET PRELOAD_TABLES="schema1.table1,schema2.table2,schema3.table3";
+```
+
+## **查看缓存状态**：
+当使用 `ALTER..PRELOAD_TABLES` 命令将表加载到计算集群时，SHOW PRELOAD显示的缓存状态的更新可能会存在延迟，但是实际上缓存表已经生效。通常情况下，这种延迟大约为 10 分钟。
+
+
+* 显示当前虚拟集群的预加载表/分区状态：
+
+```SQL
+SHOW PRELOAD CACHED STATUS;
+```
+
+* 显示指定虚拟集群的预加载表/分区状态：
+
+```SQL
+SHOW VCLUSTER preload_ap_vc_test PRELOAD CACHED STATUS;
+```
+
+* 通过表名过滤预加载状态信息：
+
+```SQL
+SHOW VCLUSTER preload_ap_vc_test PRELOAD CACHED STATUS WHERE table LIKE '%x_test';
+```
+
+* 显示虚拟集群的预加载缓存汇总信息：
+
+```SQL
+SHOW EXTENDED PRELOAD CACHED STATUS;
+```
+
+## 注意事项
+
+* 集群支持自动启停，当集群停止时，缓存的表将自动释放。在 AP 型集群中，重新启动时只会缓存最新写入的数据或者分区。
+* 执行缓存命令后，只有新写入的数据才会被缓存

+# 计算集群规格代码变更说明
+
+随着越来越多的客户使用云器Lakehouse的计算集群，我们发现原本以2的指数倍增长的计算集群规格，可能会造成规格间隔过大、资源浪费。因此，我们修改了计算集群的规格，现在可以以更细粒度的方式规划计算集群的规格，提高资源利用效率，降低成本。
+
+规格代码具体调整如下：
+
+## **原计算集群规格**
+
+从XS到5XLarge，规格增加一级，算力资源增加一倍，同时资源消耗也增加一倍：
+
+|         |        |                           |
+| ------- | ------ | ------------------------- |
+| **规格**  | **简称** | **每小时消耗**（**CRU**\***时**） |
+| XSMALL  | XS     | 1                         |
+| SMALL   | S      | 2                         |
+| MEDIUM  | M      | 4                         |
+| LARGE   | L      | 8                         |
+| XLARGE  | XL     | 16                        |
+| 2XLARGE | 2XL    | 32                        |
+| 3XLARGE | 3XL    | 64                        |
+| 4XLARGE | 4XL    | 128                       |
+| 5XLARGE | 5XL    | 256                       |
+
+## **新计算集群规格**
+
+每种类型的计算集群，均以CRU（Compute Resource Unit）表示其规格。不同类型的计算集群，由于其适合的任务和资源配置不同，可以指定的规格也不同。
+
+各类计算集群的规格详细说明如下：
+
+| **类型**                         | **最小规格**（**CRU**） | **最大规格**（**CRU**） | **默认值**（**CRU**） | **步长**&#xA;（规格增减的最小单位）                                                        |
+| ------------------------------ | ----------------- | ----------------- | ---------------- | ----------------------------------------------------------------------------- |
+| 通用型&#xA;（GP Vcluster）          | 1                 | 256               | 1                | 1（规格示例：1，2，3，4，5，6...256）                                                      |
+| 分析型&#xA;（AP Vcluster）          | 1                 | 256               | 1                | 2的n次幂（规格示例：1，2，4，8，16，32，64，128，256）                                          |
+| 同步型&#xA;（Integration Vcluster） | 0.25              | 256               | 0.5              | 1（规格序列如下：有0.25 CRU和0.5 CRU两个特殊的小规格，其余规格的步长为1。规格示例：0.25，0.5，1，2，3，4，5，6...256） |
+
+每个集群每小时消耗的计算资源量为其CRU规格\*1小时，即单位为CRU\*时。例如规格为3 CRU的分析型计算集群，运行1小时的资源消耗为 3CRU \* 1小时=3CRU\*时。其费用也按照计算集群所在区域的“CRU\*时”的单价计算。
+
+## **兼容性说明**
+
+### 新旧计算集群规格对应关系
+
+存量计算集群的规格会自动转换为新规格，单位时间的计算资源消耗量和费用均不会发生变化。具体的规格对应关系如下：
+
+|         |         |          |
+| ------- | ------- | -------- |
+| **原取值** | **新取值** | **适用范围** |
+| XSMALL  | 1       | 所有类型VC   |
+| SMALL   | 2       | 所有类型VC   |
+| MEDIUM  | 4       | 所有类型VC   |
+| LARGE   | 8       | 所有类型VC   |
+| XLARGE  | 16      | 所有类型VC   |
+| 2XLARGE | 32      | 所有类型VC   |
+| 3XLARGE | 64      | 所有类型VC   |
+| 4XLARGE | 128     | 所有类型VC   |
+| 5XLARGE | 256     | 所有类型VC   |
+
+### SQL新建计算集群
+
+新规格代码上线后，新建和修改计算集群的SQL语句均将暂时兼容旧的规格代码，即Vcluster\_size 参数可同时支持以数字表达或以'XSMALL、SMALL'等代码表达的计算集群规格。请尽快迁移至使用数字表达计算集群规格的方式，以避免在切换至不兼容版本后影响计算集群的正常创建。
+
+新建集群示例代码如下：
+
+```SQL
+-- 创建计算集群
+CREATE VCLUSTER [IF NOT EXISTS] vc_name
+objectProperties
+[COMMENT '']
+[WITH PROPERRIES ("key"="value"  "key"="value" ...)]
+--参数变更   
+objectProperties ::=
+            VCLUSTER_SIZE = NUM --0.25-256 。兼容支持 XSMALL | SMALL | MEDIUM | LARGE | XLARGE | 2XLARGE | 3XLARGE | 4XLARGE | 5XLARGE 
+```
+
+### Web端新建计算集群
+
+Web端新建和修改计算集群时，变更为输入或指定以数字表达的计算集群规格，示例如下：
+
+:-: ![](.topwrite/assets/image_1733751304880.png =420)
+
+### SQL端查询计算集群
+
+SQL端查询计算集群规格时，所有表示计算集群规格的字段（vcluster\_size, min\_vcluster\_size，max\_vcluster\_size以及current\_vcluster\_size四个字段），均转换为以数字表达的集群大小。转换规则详见上文的“新旧计算集群规格对应关系”。
+
+### Web端查询计算集群
+
+Web端计算集群的规格变更为以数字表达计算集群规格。
+
+:-: ![](.topwrite/assets/image_1733751321636.png)
+
+## 计费说明
+
+计算集群规格代码变更前后，同规格计算集群的资源消耗和每小时费用**不会变更**。仅涉及计费单位的变更：计算规格由"XS、S”等字母表达变更为 1CRU，2CRU的数字表达；计算资源消耗量单位由CRU变更为CRU\*时。
+
+变更后，估算某个集群每小时的资源消耗量和费用更加简便。
+
+无需强记“S”规格对应每小时消耗2 CRU，再乘以资源单价来估算费用。
+
+2 CRU的计算集群，每小时就消耗“2 CRU\*时”，仅需对应单价即可计算每小时费用。

+## 概述
+
+Lakehouse 支持向量类型、向量搜索函数和向量索引，通过向量搜索函数可以实现向量检索场景。
+向量数据类型是具有固定维度的数值有序集合。向量可以表示多种数据，例如从大型语言模型 (LLM) 获得的向量嵌入、图像或面部的向量嵌入、金融时间序列、空间坐标、速度、颜色等。使用向量数据类型可以更轻松地插入、加载和查询向量。
+
+Lakehouse 提供了向量类型和向量索引检索功能。现代深度学习技术可以从非结构化数据（如文本和图像）中创建向量嵌入，即结构化的数值表示形式，同时保留生成向量的几何结构中的相似性和不相似性的语义概念。Lakehouse 提供了 VECTOR 类型来存储这些转化后的向量，构建索引可以提高向量搜索性能。
+
+## Lakehouse支持的向量功能
+
+* **向量存储**：使用 `VECTOR` 类型存储向量。
+* **向量索引**：采用 HNSW（Hierarchical Navigable Small World）算法构建向量索引，以加速计算。
+* **距离计算**：支持多种函数计算向量相似度，包括 `L2_DISTANCE` 和 `COSINE_DISTANCE` 等函数。
+
+## 使用注意事项
+
+* 当前版本的向量类型不支持比较操作，因此不能用于`ORDER BY`或`GROUP BY`子句中。
+* 向量索引的性能与内存缓存、磁盘缓存直接相关，建议单独占用 VC 使用。与其他场景混合使用会相互挤占缓存，可能导致性能不如预期。
+
+## Lakehouse向量使用
+
+**创建向量**
+
+```SQL
+
+CREATE TABLE test_vector1 (
+    vec vector(float, 4),
+    id int,
+    index test_vector1_vec_idx  (vec) using vector properties (
+        "scalar.type" = "f32",
+        "distance.function" = "l2_distance"
+    )
+);
+```
+
+properties 中支持指定的参数参考 [创建向量索引文档](create-vector-index.md)
+
+**插入数据**
+
+* 使用SQL插入
+
+```SQL
+INSERT INTO test_vector1 (vec, id) VALUES
+    (vector(0.1, 0.2, 0.3, 0.4), 1),
+    (vector(0.5, 0.6, 0.7, 0.8), 2),
+    (vector(0.9, 1.0, 1.1, 1.2), 3),
+    (vector(1.3, 1.4, 1.5, 1.6), 4),
+    (vector(1.7, 1.8, 1.9, 2.0), 5),
+    (vector(2.1, 2.2, 2.3, 2.4), 6),
+    (vector(2.5, 2.6, 2.7, 2.8), 7),
+    (vector(2.9, 3.0, 3.1, 3.2), 8),
+    (vector(3.3, 3.4, 3.5, 3.6), 9),
+    (vector(3.7, 3.8, 3.9, 4.0), 10);
+```
+
+* 如果您是通过外部系统写入到 Lakehouse 中，当前 Lakehouse 不支持直接写入 vector 类型，您可以写成 array 类型，再使用 `INSERT OVERWRITE SELECT CAST(array_col AS VECTOR)` 进行转换。
+
+  * ```SQL
+    CREATE  TABLE arraytable (vec ARRAY,id int);
+    SELECT vec::VECTOR(FLOAT, 3)
+    FROM arraytable;
+    ```
+
+* 如果数据在对象存储中，您可以直接使用volume导入vector类型
+
+**向量检索**
+
+用户可通过配置参数 `cz.vector.index.search.ef` 来调整**探索因子（ef）**，该参数用于控制在查询阶段搜索图中遍历的节点数量，从而在检索性能与准确率之间实现灵活权衡。较大的 `ef` 值通常可以提高检索的准确性，但可能增加查询延迟；较小的值则能提升检索速度，但可能牺牲部分精度。
+
+```SQL
+SET cz.vector.index.search.ef=64;
+SELECT id, l2_distance(vec, vector(1,2,3,4)) AS dist FROM test_vector1 WHERE l2_distance(vec, vector(1,2,3,4)) < 4.0 ORDER BY dist LIMIT 5;
+```
+
+当需要确认向量索引是否生效时，可以使用 `\`EXPLAIN SELECT ...\`` 语法查看 TableScan 算子中是否包含 `vector_index_search_type` 字样。
+
+```SQL
+PhysicalTableSink()
+  PhysicalLocalSort_L3($10)
+    PhysicalShuffleRead()
+      PhysicalShuffleWrite_SINGLETON()
+        PhysicalLocalSort_L3($10)
+          PhysicalCalc(NVL($4292967295, L2_DISTANCE($0, [1,2,3,4])), LT(_TRY_TO_FLOAT64(#0), 3.020000), $1) as [1, 10]
+            PhysicalTableScan(test_vector1, LT(_TRY_TO_FLOAT64(NVL(@4292967295, L2_DISTANCE(#0, [1,2,3,4]))), 3.020000, expr_key=4292967295, limit=3, vector_index_search_type=ann), F4M:LT(_TRY_TO_FLOAT64(L2_DISTANCE(#0, [1,2,3,4])), 3.020000), GEN:[L2_DISTANCE(#0, [1,2,3,4]) as 4292967295], vec, id) as [0, 1, 4292967295]
+```
+
+当向量索引未生效时，会退化到暴力检索。
+
+## 与倒排索引同时使用
+
+向量索引只能解决向量检索问题，当查询带上其他字段相关的过滤条件时，会直接退化为暴力算法。为了解决这个问题，一般有两种思路。
+
+1. 先在子查询中执行向量检索，再在外层查询中执行其他字段的过滤条件。这种方案虽然查询性能快，但如果非向量字段的过滤性比较高，最终的输出结果往往少于用户的期望数据条数，甚至为空。
+
+```SQL
+SELECT id, doc, dist FROM (
+    SELECT id, doc, l2_distance(vec, vector(1,2,3,4)) as dist FROM some_table WHERE l2_distance(vec, vector(1,2,3,4)) < 1000 ORDER BY dist LIMIT 100
+) WHERE doc like '%hello%';
+```
+
+2. 在常用的非向量字段上构建倒排索引，与向量检索一同使用：
+
+```SQL
+-- 建表
+CREATE TABLE test_vector1 (
+    vec vector(float, 4),
+    index test_vector1_vec_idx  (vec) using vector properties (
+        "scalar.type" = "f32",
+        "distance.function" = "l2_distance"
+    ),
+    doc string,
+    index test_vector1_doc_idx on (doc) using inverted properties ('analyzer' = 'keyword');,
+    id int
+) ;
+
+-- 查询
+SET cz.sql.index.prewhere.enabled=true; -- 当前需要设置开关，后续版本会默认开启
+SELECT id, doc, l2_distance(vec, vector(1,2,3,4)) as dist FROM some_table WHERE match_regexp(doc, '.*hello.*', map('analyzer', 'keyword')) AND l2_distance(vec, vector(1,2,3,4)) < 1000 ORDER BY dist LIMIT 100
+```
+
+上述例子中，执行流程为：先根据 `match_regexp(doc, '.*hello.*', map('analyzer', 'keyword'))` 使用倒排索引过滤出命中的行，再从命中的行中执行向量检索。
+
+## 向量检索查询时支持的参数
+
+| Name                                                  | Default Value | Notes                                        |
+| ----------------------------------------------------- | ------------- | -------------------------------------------- |
+| Name                                                  | Default Value | Notes                                        |
+| ----------------------------------------------------- | ------------- | -------------------------------------------- |
+| cz.storage.parquet.vector.index.read.memory.cache     | false         | 是否使用内存缓存                                     |
+| cz.storage.parquet.vector.index.read.local.cache      | false         | 是否使用本地SSD缓存                                  |
+| cz.storage.parquet.vector.index.read.vectors.ondemand | adaptive      | 是否按需加载向量索引（比使用内存缓存稍慢）                        |
+| cz.storage.parquet.vector.index.write.parallel        | 0             | 是否开启并行写入，0表示关闭，8表示8个线程写入。注意，性能提升比例并不与线程数成正比。 |
+
+使用示例：在 SQL 查询时设置以下参数一起执行。
+
+```SQL
+SET cz.sql.index.prewhere.enabled=true; -- 当前需要设置开关，后续版本会默认开启
+SELECT id, doc, l2_distance(vec, vector(1,2,3,4)) as dist FROM some_table WHERE match_regexp(doc, '.*hello.*', map('analyzer', 'keyword')) AND l2_distance(vec, vector(1,2,3,4)) < 1000 ORDER BY dist LIMIT 100
+```
+
+## 计费
+
+* 存储资源：向量索引会创建向量索引文件，该文件与数据文件都保存在对象存储中，统一计费。

+# VECTOR
+## 语法
+
+```Plain
+vector(scalar_type, dimension)
+vector(dimension)
+```
+
+* scalar type 为向量中的元素类型，可选，默认值是float类型。支持tinyint/int/float
+* dimension：仅指定维度
+
+**示例**：
+
+```SQL
+CREATE TABLE test_vector (
+    vec1 vector(float, 512),  -- 指定元素类型为float，维度为512
+    vec2 vector(512),         -- 默认元素类型为float，维度为512
+    vec3 vector(tinyint, 128) -- 指定元素类型为tinyint，维度为128
+);
+```
+
+**创建向量**：
+
+```SQL
+SELECT vector(1, 2, 3); -- 根据提供的值自动推导元素类型，创建一个向量
+```
+
+## 使用限制
+
+* 当前版本的向量类型不支持比较操作，因此不能用于`ORDER BY`或`GROUP BY`子句中。
+
+## 向量类型转换
+
+向量类型支持与数组类型之间的转换，以及从字符串类型转换为向量类型：
+
+1. **隐式转换**：在大多数情况下，向量类型可以直接转换为数组类型，尽量保持元素类型不变。
+2. **数组转向量**：数组类型也可以转换为向量类型，但必须确保数组长度与向量维度相匹配。不匹配时，转换结果为`NULL`。
+3. **字符串转向量**：支持将符合格式`'[1, 2, 3]'`的字符串转换为向量类型（多余空格会被忽略）。
+
+
+**示例**：
+
+```SQL
+-- 将向量隐式转换为数组
+SELECT array_append(vector(1,2,3), 4);
+
+-- 计算两个向量之间的L2距离
+SELECT l2_distance(array(1,2,3), vector(3,2,1));
+
+-- 显式将字符串转换为向量
+SELECT cast('[1,2,3,4]' as vector(4));
+```

+# Lakehouse VECTOR数据处理使用指南
+
+## 向量数据的原生支持与实践
+
+***
+
+## 写在前面
+
+### 您可能遇到的向量数据处理场景
+
+#### 场景1：文档相似度检索系统
+
+**当前在 Hive/Spark 中的常见做法**：
+
+```sql
+-- 在Hive中存储文档向量
+CREATE TABLE document_embeddings (
+    doc_id STRING,
+    title STRING, 
+    content STRING,
+    embedding ARRAY<DOUBLE>  -- 存储LLM生成的向量
+) PARTITIONED BY (dt STRING);
+
+-- 相似度计算需要复杂的UDF
+CREATE FUNCTION cosine_similarity_udf(vec1 ARRAY<DOUBLE>, vec2 ARRAY<DOUBLE>) 
+RETURNS DOUBLE
+LANGUAGE PYTHON AS $
+import numpy as np
+def cosine_similarity_udf(vec1, vec2):
+    return np.dot(vec1, vec2) / (np.linalg.norm(vec1) * np.linalg.norm(vec2))
+$;
+
+-- 查询需要手动维度检查和UDF调用
+SELECT doc_id, title,
+    cosine_similarity_udf(embedding, array(0.1, 0.2, 0.3, ...)) as score
+FROM document_embeddings 
+WHERE size(embedding) = 1536  -- 手动维度检查
+    AND dt >= '2024-01-01'
+ORDER BY score DESC 
+LIMIT 10;
+```
+
+**面临的技术挑战**：
+
+* **实现复杂**：需要自定义UDF实现距离计算函数
+* **无专门索引**：数组类型无法建立针对相似度的索引
+* **类型安全问题**：数组长度不固定，容易出现维度不匹配错误
+* **性能限制**：大规模向量计算时缺乏专门优化
+
+#### 场景2：推荐系统用户特征匹配
+
+**在 Spark 中的典型实现**：
+
+```python
+# Spark中的用户向量相似度计算
+from pyspark.sql.functions import *
+from pyspark.ml.linalg import Vectors
+
+# 需要自定义函数实现相似度计算
+def cosine_similarity_udf(vec1, vec2):
+    from pyspark.ml.linalg import Vectors
+    import numpy as np
+    v1 = np.array(vec1)
+    v2 = np.array(vec2)
+    return float(np.dot(v1, v2) / (np.linalg.norm(v1) * np.linalg.norm(v2)))
+
+# 注册UDF
+cosine_udf = udf(cosine_similarity_udf, DoubleType())
+
+# 查询相似用户
+similar_users = user_features.crossJoin(user_features.alias("other")) \
+    .filter(col("user_id") != col("other.user_id")) \
+    .withColumn("similarity", cosine_udf(col("features"), col("other.features"))) \
+    .filter(col("similarity") > 0.8) \
+    .orderBy(desc("similarity"))
+```
+
+**常见的技术痛点**：
+
+* **架构复杂**：向量计算与数据存储分离，增加系统复杂度
+* **开发成本**：需要实现和维护自定义的相似度计算逻辑
+* **性能瓶颈**：大规模向量计算时缺乏专门的加速机制
+* **错误处理**：缺乏对向量维度的编译时检查
+
+### 为什么需要向量数据类型
+
+基于以上场景中的技术挑战，VECTOR数据类型的设计目标是：
+
+**解决类型安全问题**：
+
+* 提供固定维度的向量类型定义
+* 编译时进行维度匹配检查
+* 避免运行时的维度不匹配错误
+
+**简化开发流程**：
+
+* 内置常用的向量距离计算函数
+* 无需编写和维护自定义UDF
+* 与标准SQL语法完全兼容
+
+**提升查询性能**：
+
+* 支持专门的向量索引
+* 针对向量计算进行优化
+* 支持高效的相似度检索

+
+-- 3. 创建向量索引
+CREATE VECTOR INDEX embedding_idx ON TABLE document_embeddings(embedding) 
+PROPERTIES(
+    "distance.function" = "cosine_distance",
+    "scalar.type" = "f32"
+);
+

+    
+    INDEX embedding_idx (embedding) USING VECTOR PROPERTIES (
+        "distance.function" = "cosine_distance"
+    )
+);
+
+-- 使用内置函数，维度自动检查
+SELECT doc_id FROM docs_vector 
+WHERE COSINE_DISTANCE(embedding, vector(0.1, 0.2, ...)) < 0.8
+ORDER BY doc_id LIMIT 10;

+
+## 📊 VECTOR数据类型规范
+
+### 类型定义语法
+
+```sql
+VECTOR(scalar_type, dimension)
+```
+
+### 支持的标量类型
+
+| 标量类型    | 存储大小  | 数值范围       | 适用场景              | 索引支持  |
+| ------- | ----- | ---------- | ----------------- | ----- |
+| FLOAT   | 4字节/维 | 32位浮点数     | 通用向量存储，如embedding | ✅ f32 |
+| INT     | 4字节/维 | 32位整数      | 整数特征向量，如计数        | ❌     |
+| TINYINT | 1字节/维 | -128 到 127 | 压缩存储，如二进制向量       | ✅ i8  |
+
+> **💡 建议**：生产环境推荐使用FLOAT类型，兼容性和性能最佳
+
+### 向量创建方法
+
+```sql
+-- 直接创建向量
+SELECT vector(1.0, 2.0, 3.0);              -- 创建3维浮点向量
+SELECT vector(1, 2, 3);                     -- 创建3维整数向量
+
+-- 从其他类型转换
+SELECT cast(array(1,2,3) as VECTOR(INT, 3));     -- 数组转向量
+SELECT cast('[1,2,3]' as VECTOR(INT, 3));        -- JSON字符串转向量
+
+-- 在表定义中使用
+CREATE TABLE feature_vectors (
+    id BIGINT,
+    dense_features VECTOR(FLOAT, 128),       -- 稠密特征
+    sparse_features VECTOR(INT, 1000)        -- 稀疏特征
+);

+
+-- ❌ 错误示例：整数向量可能导致精度问题
+SELECT L2_NORMALIZE(vector(3, 4)) as normalized_vector;
+-- 可能结果：[0, 0]
+```
+
+**功能**：将向量标准化为单位长度（L2范数为1）
+**适用场景**：余弦相似度计算的预处理
+
+### 函数使用注意事项
+
+* 所有距离函数要求输入向量维度相同，否则会报编译时错误
+* 函数支持向量类型与数组类型的混合计算
+* 归一化函数返回相同维度的向量类型

+
+## ⚠️ 重要避坑指南
+
+### 🚨 向量查询限制
+
+经过UAT环境实际测试，发现两种不同的错误模式：
+
+#### 1. 维度不匹配错误（预期行为）
+
+```sql
+-- ❌ 错误示例：使用5维向量查询128维数据
+SELECT id FROM embeddings_table 
+WHERE COSINE_DISTANCE(embedding_128d, vector(0.1, 0.2, 0.3, 0.4, 0.5)) < 0.8;
+
+-- 错误信息：
+-- function 'COSINE_DISTANCE' cannot be resolved, 
+-- expect 'vector shall have the same dimension'
+```
+
+**解决方法**：确保查询向量与表中向量维度完全一致
+
+#### 2. Generated Column内部错误（当前限制）
+
+```sql
+-- ❌ 问题查询：在SELECT中返回距离计算
+SELECT id, content,
+    COSINE_DISTANCE(embedding, vector(...)) as distance
+FROM embeddings_table 
+ORDER BY distance LIMIT 10;
+
+-- 可能错误：
+-- Generated column 4292967295(generated_field_4292967295) is not filled for VECTOR
+```
+
+**当前可用的查询模式**：
+
+```sql
+-- ✅ 推荐：WHERE子句中的向量过滤
+SELECT id, content FROM embeddings_table 
+WHERE COSINE_DISTANCE(embedding, vector(...)) < 0.8
+ORDER BY id LIMIT 10;
+
+-- ✅ 可用：简单的向量函数
+SELECT COSINE_DISTANCE(embedding, embedding) as self_distance
+FROM embeddings_table;
+
+-- ❌ 避免：复杂的SELECT返回距离计算并排序
+```
+
+### 🛠️ 函数使用避坑
+
+#### L2\_NORMALIZE函数类型要求
+
+```sql
+-- ✅ 正确：使用浮点数向量
+SELECT L2_NORMALIZE(vector(3.0, 4.0)) as normalized;
+-- 结果：[0.6, 0.8]
+
+-- ❌ 错误：使用整数向量
+SELECT L2_NORMALIZE(vector(3, 4)) as normalized;
+-- 可能结果：[0, 0] （精度丢失）
+```
+
+#### 索引参数规范
+
+```sql
+-- ✅ 正确：使用完整参数名
+CREATE VECTOR INDEX idx ON TABLE t(col) PROPERTIES(
+    "distance.function" = "cosine_distance",  -- 完整函数名
+    "scalar.type" = "f32"                    -- 标准类型名
+);
+
+-- ❌ 错误：使用简化名称
+CREATE VECTOR INDEX idx ON TABLE t(col) PROPERTIES(
+    "distance.function" = "cosine",          -- 会报错
+    "scalar.type" = "float"                  -- 会报错
+);
+```
+
+### 🎯 最佳实践建议
+
+#### 查询模式选择
+
+| 使用场景    | 推荐模式                                     | 避免模式                            |
+| ------- | ---------------------------------------- | ------------------------------- |
+| 相似度过滤   | `WHERE COSINE_DISTANCE(...) < threshold` | `ORDER BY COSINE_DISTANCE(...)` |
+| Top-K检索 | WHERE过滤 + 简单排序                           | 距离计算 + 排序                       |
+| 批量计算    | 分步骤查询                                    | 复杂嵌套查询                          |
+
+#### 性能优化策略
+
+```sql
+-- ✅ 推荐：利用索引的过滤查询
+SELECT doc_id, title FROM knowledge_base 
+WHERE COSINE_DISTANCE(embedding, ?) < 0.7
+ORDER BY doc_id LIMIT 10;
+
+-- ✅ 可选：分步骤的Top-K检索
+-- 步骤1：过滤候选
+CREATE VIEW candidates AS 
+SELECT doc_id, title FROM knowledge_base 
+WHERE COSINE_DISTANCE(embedding, ?) < 0.8;
+
+-- 步骤2：精确排序（如需要）
+SELECT doc_id, title FROM candidates ORDER BY doc_id LIMIT 10;
+```
+

+
+## 🔄 迁移策略
+
+### 迁移价值评估
+
+在决定是否迁移到VECTOR类型之前，建议先评估您的使用场景：
+
+#### 高价值迁移场景
+
+* **频繁的向量相似度计算**：如推荐系统、文档检索、图像匹配
+* **大规模向量数据**：超过百万级别的向量数据查询
+* **复杂的UDF维护**：当前需要维护多个自定义向量计算函数
+* **性能要求高**：对查询响应时间有严格要求的应用
+
+#### 可选迁移场景
+
+* **偶尔的向量计算**：向量计算不是核心业务流程
+* **小规模数据**：向量数据量较小，性能压力不大
+* **稳定的现有系统**：当前系统运行稳定，改动风险大于收益
+
+### 针对不同用户的迁移建议
+
+#### Spark用户迁移路径
+
+**如果您主要使用Spark MLlib进行向量计算**：
+
+```python
+# 原Spark代码
+from pyspark.ml.linalg import Vectors, VectorUDT
+from pyspark.sql.functions import udf
+
+# 自定义相似度函数
+def cosine_similarity(v1, v2):
+    # 复杂的实现逻辑
+    pass
+
+# 注册UDF
+cosine_udf = udf(cosine_similarity, DoubleType())
+```
+
+**迁移到CloudZetta VECTOR后**：
+
+```sql
+-- 直接使用内置函数和推荐查询模式
+SELECT user_id FROM user_features
+WHERE COSINE_DISTANCE(user_vector, target_vector) < 0.8;
+```
+
+**迁移收益**：
+
+* 删除自定义UDF代码
+* 利用向量索引加速查询
+* 统一在SQL中处理向量计算
+
+#### Hive用户迁移路径
+
+**如果您在Hive中使用ARRAY存储向量**：
+
+```sql
+-- 原Hive表结构
+CREATE TABLE user_embeddings (
+    user_id BIGINT,
+    features ARRAY<DOUBLE>
+) PARTITIONED BY (dt STRING);
+
+-- 需要复杂的UDF
+SELECT user_id, my_cosine_udf(features, target_array) as score
+FROM user_embeddings 
+WHERE size(features) = 128;  -- 手动维度检查
+```
+
+**迁移到 VECTOR 类型**：
+
+```sql
+-- 新的表结构
+CREATE TABLE user_embeddings_v2 (
+    user_id BIGINT,
+    features VECTOR(FLOAT, 128)  -- 类型安全
+) PARTITIONED BY (dt STRING);
+
+-- 使用内置函数和推荐模式
+SELECT user_id FROM user_embeddings_v2
+WHERE COSINE_DISTANCE(features, vector(...)) < 0.8;  -- 无需手动维度检查
+```
+
+### 评估现有系统
+
+#### 数据规模评估
+
+```sql
+-- 统计现有向量数据的规模和维度
+SELECT 
+    table_name,
+    column_name,
+    COUNT(*) as record_count,
+    AVG(size(array_column)) as avg_dimension,
+    MIN(size(array_column)) as min_dimension,
+    MAX(size(array_column)) as max_dimension,
+    COUNT(DISTINCT size(array_column)) as dimension_variants
+FROM (
+    SELECT 'user_features' as table_name, 'embedding' as column_name, embedding as array_column FROM user_features
+    UNION ALL
+    SELECT 'product_vectors' as table_name, 'features' as column_name, features as array_column FROM product_vectors
+    -- 添加其他需要评估的表
+) all_vectors
+GROUP BY table_name, column_name;
+```
+
+#### UDF复杂度评估
+
+```sql
+-- 识别当前使用的向量相关UDF
+SHOW FUNCTIONS LIKE '*similarity*';
+SHOW FUNCTIONS LIKE '*distance*';
+SHOW FUNCTIONS LIKE '*cosine*';
+SHOW FUNCTIONS LIKE '*euclidean*';
+```
+
+#### 查询频率评估
+
+```sql
+-- 分析向量计算查询的频率（如果有查询日志）
+SELECT 
+    DATE(query_time) as query_date,
+    COUNT(*) as vector_query_count
+FROM query_logs 
+WHERE query_text LIKE '%cosine%' 
+    OR query_text LIKE '%similarity%'
+    OR query_text LIKE '%distance%'
+GROUP BY DATE(query_time)
+ORDER BY query_date DESC
+LIMIT 30;
+```
+
+### 并行构建新表
+
+```sql
+-- 创建新的向量表
+CREATE TABLE embeddings_new (
+    id BIGINT,
+    content STRING,
+    embedding VECTOR(FLOAT, 768),
+    migrated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP(),
+    
+    INDEX embedding_idx (embedding) USING VECTOR PROPERTIES (
+        "distance.function" = "cosine_distance"
+    )
+);
+
+-- 数据迁移
+INSERT INTO embeddings_new (id, content, embedding)
+SELECT 
+    id,
+    content,
+    CASE 
+        WHEN size(embedding_array) = 768 
+        THEN cast(embedding_array as VECTOR(FLOAT, 768))
+        ELSE NULL
+    END as embedding
+FROM embeddings_old
+WHERE size(embedding_array) = 768;
+
+-- 构建索引
+BUILD INDEX embedding_idx ON embeddings_new;
+```
+
+### 验证迁移结果
+
+```sql
+-- 对比查询结果的一致性（使用推荐查询模式）
+WITH old_results AS (
+    SELECT id FROM embeddings_old 
+    WHERE your_cosine_udf(embedding_array, ?) > 0.8
+    ORDER BY id LIMIT 10
+),
+new_results AS (
+    SELECT id FROM embeddings_new 
+    WHERE COSINE_DISTANCE(embedding, ?) < 0.2  -- 注意距离vs相似度的转换
+    ORDER BY id LIMIT 10
+)
+SELECT 
+    COALESCE(o.id, n.id) as id,
+    CASE WHEN o.id IS NOT NULL THEN 'OLD' ELSE NULL END as in_old,
+    CASE WHEN n.id IS NOT NULL THEN 'NEW' ELSE NULL END as in_new
+FROM old_results o
+FULL OUTER JOIN new_results n ON o.id = n.id
+ORDER BY id;
+```
+
+***
+
+## 🚀 性能优化
+
+### 查询优化
+
+```sql
+-- ✅ 推荐：使用阈值过滤提升查询效率
+SELECT id, content FROM embeddings_table 
+WHERE COSINE_DISTANCE(embedding, ?) < 0.8  -- 利用向量索引过滤
+ORDER BY id LIMIT 10;
+
+-- ✅ 可选：分步骤处理复杂查询
+CREATE VIEW filtered_candidates AS
+SELECT id, content FROM embeddings_table 
+WHERE COSINE_DISTANCE(embedding, ?) < 0.8;
+
+SELECT id, content FROM filtered_candidates 
+ORDER BY id LIMIT 10;
+```
+
+### 存储优化
+
+```sql
+-- 大规模数据使用半精度存储
+CREATE TABLE large_embeddings (
+    id BIGINT,
+    embedding VECTOR(FLOAT, 1536),
+    
+    INDEX embedding_idx (embedding) USING VECTOR PROPERTIES (
+        "scalar.type" = "f16",  -- 半精度存储节省内存
+        "distance.function" = "cosine_distance"
+    )
+);
+```
+
+### 索引调优
+
+根据应用需求选择合适的索引参数：
+
+* **实时查询场景**：较小的M值和ef\_construction，使用f16类型
+* **批量分析场景**：较大的M值和ef\_construction，使用f32类型
+* **存储优化场景**：使用f16或i8类型减少内存占用
+
+***
+
+## ⚠️ 注意事项
+
+### 功能限制
+
+* 向量维度在创建时确定，不支持动态调整
+* 向量不能用作分区键
+* JACCARD\_DISTANCE和HAMMING\_DISTANCE函数有特殊的类型要求
+* **当前版本的复杂 SELECT 查询存在限制，建议使用 WHERE 过滤模式**
+
+### 索引管理
+
+* CREATE INDEX只对新增数据生效，已有数据需要执行BUILD INDEX
+* 向量索引的性能与内存缓存密切相关
+* 建议为向量查询使用专门的Virtual Cluster
+
+### 故障排除
+
+| 问题                 | 可能原因         | 解决方法                     |

+| 查询性能差              | 索引未生效        | 检查索引状态，执行BUILD INDEX     |
+| 维度不匹配错误            | 向量维度不一致      | 检查VECTOR类型定义和输入数据维度      |
+| Generated column错误 | 复杂SELECT查询限制 | 使用WHERE过滤模式替代            |
+| L2\_NORMALIZE返回零向量 | 使用整数向量       | 改用浮点数向量：vector(3.0, 4.0) |
+| 索引参数错误             | 参数名称不规范      | 使用完整参数名：cosine\_distance |
+| 内存不足               | 向量索引占用过多内存   | 调整索引参数或增加集群资源            |

+# Lakehouse 向量索引创建指南
+
+## 概述
+
+Lakehouse 提供完整的向量检索能力，包括向量数据类型、搜索函数和专用索引。向量作为固定维度的数值集合，可以表示 LLM 生成的文本嵌入、图像特征、时序数据等多种信息。
+系统原生支持 VECTOR 类型，能够高效存储和查询由大语言模型（LLM）等深度学习模型生成的向量嵌入。这些向量嵌入将非结构化数据（如文本、图像）转化为保留语义相似性的数值表示。通过构建专门的向量索引，Lakehouse 可以在海量数据中实现毫秒级的相似性搜索，为基于 LLM 的 RAG 应用、智能问答、语义搜索等 AI 场景提供高性能的基础设施支持。
+
+## 1. 准备工作
+
+### 1.1 创建测试 Schema
+
+```sql
+-- 创建一个专门用于向量索引测试的 schema
+CREATE SCHEMA IF NOT EXISTS vector_demo COMMENT '向量索引演示';
+
+-- 切换到新创建的 schema
+USE SCHEMA vector_demo;
+```
+
+### 1.2 准备向量生成函数
+
+Lakehouse 支持创建 AI 函数，可以将文本转换为向量表示，请参考：[创建 Embedding 函数](https://www.yunqi.tech/documents/Create_Embeding_Function)
+
+```sql
+-- 函数签名
+-- fc_embeddings(mode, text, api_key, model, dimension)
+-- 参数说明：
+-- mode: 'text' - 文本模式
+-- text: 要转换的文本内容
+-- api_key: API密钥 (请替换为您的实际密钥)
+-- model: 模型名称，如 'text-embedding-v4'
+-- dimension: 向量维度，如 1024
+
+-- 测试向量生成函数
+SELECT public.fc_embeddings(
+    'text', 
+    'hello world', 
+    '${API_KEY}', 
+    'text-embedding-v4',
+    1024
+) as embedding;
+```
+
+## 2. 创建包含向量列的表
+
+### 创建产品描述表
+
+```sql
+-- 创建产品表，包含向量列（简化版本，避免IDENTITY问题）
+CREATE TABLE IF NOT EXISTS vector_demo.product_embeddings (
+    product_id INT COMMENT '产品ID',
+    product_name VARCHAR(255) NOT NULL COMMENT '产品名称',
+    category VARCHAR(100) COMMENT '产品类别',
+    description STRING COMMENT '产品描述',
+    embedding VECTOR(FLOAT, 1024) COMMENT '产品描述的向量表示',
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP() COMMENT '创建时间',
+    
+    -- 创建向量索引（简化的语法）
+    INDEX idx_product_embedding (embedding) USING VECTOR
+) 
+COMMENT '产品向量表';
+
+```
+
+## 3. 插入向量数据
+
+### 3.1 使用向量生成函数插入数据
+
+**重要提示**：使用 `fc_embeddings` 函数生成的向量需要显式转换为 `VECTOR` 类型。
+
+```sql
+-- 插入向量数据，注意需要使用 CAST 转换
+INSERT INTO vector_demo.product_embeddings (product_id, product_name, category, description, embedding)
+VALUES

+
+## 4. 构建向量索引
+
+> ### 对已有数据构建索引
+>
+> 如果想对表中已经存在的数据创建索引，需要使用 BUILD INDEX 命令构建索引（新插入的数据会自动构建索引）。
+>
+> ```sql
+> -- 构建向量索引（实际验证过的命令）
+> BUILD INDEX idx_embedding ON vector_demo.simple_embeddings;
+>
+> -- 构建文档表的向量索引（指定范围）
+> BUILD INDEX idx_doc_embedding ON vector_demo.document_embeddings 
+> WHERE create_date >= '2024-01-01' AND create_date <= '2024-12-31';
+> ```
+
+### 4.1 监控索引构建进度
+
+```sql
+-- 查看表的索引列表
+SHOW INDEXES FROM vector_demo.product_embeddings;
+
+-- 查看表的详细信息，包括索引
+DESC EXTENDED vector_demo.product_embeddings ;
+```
+
+## 5. 使用向量索引进行相似度搜索
+
+### 5.1 基本向量搜索
+
+```sql
+WITH query_vector AS (
+    SELECT CAST(public.fc_embeddings(
+        'text', 
+        '拍照功能强大的手机，相机系统好，影像能力出色', 
+        '${API_KEY}', 
+        'text-embedding-v4',
+        1024
+    ) AS VECTOR(FLOAT, 1024)) as vec
+)
+SELECT 
+    p.product_id,
+    p.product_name,
+    p.category,
+    p.description,
+    cosine_distance(p.embedding, q.vec) as similarity_score
+FROM vector_demo.product_embeddings p, query_vector q
+ORDER BY similarity_score ASC
+LIMIT 5;
+
+```
+
+展示结果：
+
+### ![](.topwrite/assets/vector.jpeg)
+
+### 5.3 带过滤条件的向量搜索
+
+```sql
+WITH query_vector AS (
+    SELECT CAST(public.fc_embeddings(
+        'text', 
+        '国产高端旗舰手机', 
+        '${API_KEY}', 
+        'text-embedding-v4',
+        1024
+    ) AS VECTOR(FLOAT, 1024)) as vec
+)
+SELECT 
+    product_id,
+    product_name,
+    description,
+    ROUND(cosine_distance(embedding, vec), 4) as distance
+FROM vector_demo.product_embeddings, query_vector
+WHERE product_name NOT LIKE '%iPhone%'  -- 排除苹果产品
+ORDER BY distance ASC
+LIMIT 3;
+```
+
+展示结果：
+
+![](.topwrite/assets/vector_search_w_filter.jpeg)
+
+## 6. 向量索引优化建议
+
+### 6.1 距离函数选择
+
+| 距离函数                   | 适用场景  | 特点              |
+| ---------------------- | ----- | --------------- |
+| cosine_distance       | 文本相似度 | 不受向量长度影响，适合文本嵌入 |
+| l2_distance           | 图像特征  | 欧氏距离，对绝对差异敏感    |
+| negative_dot_product | 推荐系统  | 点积的负值，适合评分预测    |
+
+### 6.2 参数调优
+
+```sql
+-- 高精度配置（查询准确但较慢）
+CREATE INDEX idx_high_precision (embedding) USING VECTOR 
+PROPERTIES(
+    "m" = "64",
+    "ef.construction" = "500",
+    "scalar.type" = "f32"
+);
+
+-- 高性能配置（查询快速但精度略低）
+CREATE INDEX idx_high_performance (embedding) USING VECTOR 
+PROPERTIES(
+    "m" = "8",
+    "ef.construction" = "100",
+    "scalar.type" = "f16",
+    "compress.codec" = "lz4"
+);
+```
+
+### 6.3 存储优化
+
+```sql
+-- 使用向量列复用减少存储
+CREATE INDEX idx_storage_optimized (embedding) USING VECTOR 
+PROPERTIES(
+    "reuse.vector.column" = "true",
+    "scalar.type" = "i8"  -- 使用8位整数进一步压缩
+);
+```
+
+## 7. 管理向量索引
+
+### 7.1 查看索引信息
+
+```sql
+-- 查看表的所有索引
+SHOW INDEXES FROM vector_demo.product_embeddings;
+
+-- 查看索引详细信息
+DESC INDEX idx_product_embedding ON vector_demo.product_embeddings;
+```
+
+### 7.2 删除和重建索引
+
+```sql
+-- 删除索引
+DROP INDEX idx_product_embedding ON vector_demo.product_embeddings;
+
+-- 重新创建索引（使用新参数）
+CREATE INDEX idx_product_embedding_v2 ON vector_demo.product_embeddings(embedding) 
+USING VECTOR PROPERTIES(
+    "distance.function" = "negative_dot_product",
+    "m" = "24",
+    "ef.construction" = "300"
+);
+
+-- 构建新索引
+BUILD INDEX idx_product_embedding_v2 ON vector_demo.product_embeddings;
+```
+
+## 8. 性能监控和故障排查
+
+### 8.1 查询性能分析
+
+```sql
+-- 使用 EXPLAIN 分析查询计划
+EXPLAIN 
+WITH query_vector AS (
+    SELECT public.fc_embeddings('text', '测试查询', '${API_KEY}', 'text-embedding-v4', 1024) as vec
+)
+SELECT * FROM vector_demo.product_embeddings p, query_vector q
+ORDER BY cosine_distance(p.embedding, q.vec) ASC
+LIMIT 10;
+```
+
+### 8.2 常见问题处理
+
+1. **索引构建失败**
+   * 检查内存是否充足
+   * 确认向量维度一致
+   * 验证向量数据完整性
+
+2. **查询性能慢**
+   * 调整 m 和 ef.construction 参数
+   * 考虑使用更小的 scalar.type
+   * 检查是否正确使用了索引
+
+3. **精度不足**
+   * 增加 m 值
+   * 提高 ef.construction
+   * 使用 f32 而非压缩格式
+
+## 重要注意事项
+
+1. **向量类型转换**：使用 `fc_embeddings` 函数生成的向量结果为 String 类型，需使用 `CAST` 转换为 `VECTOR(FLOAT, 1024)` 类型。
+
+2. **BUILD INDEX**：对于已有数据的表，必须执行 BUILD INDEX 命令来构建索引，否则向量搜索性能会受影响。
+
+3. **距离函数选择**：
+   * `cosine_distance`：适用于文本嵌入，值越小越相似
+   * `l2_distance`：欧氏距离，适用于图像特征
+   * `negative_dot_product`：点积的负值，适用于推荐系统
+
+4. **向量检索查询时支持的参数**
+
+   | Name                                                  | Default Value | Notes                                        |
+   | ----------------------------------------------------- | ------------- | -------------------------------------------- |
+   | cz.storage.parquet.vector.index.read.memory.cache     | false         | 是否使用内存缓存                                     |
+   | cz.storage.parquet.vector.index.read.local.cache      | false         | 是否使用本地SSD缓存                                  |
+   | cz.storage.parquet.vector.index.read.vectors.ondemand | adaptive      | 是否按需加载向量索引（比使用内存缓存稍慢）                        |
+   | cz.storage.parquet.vector.index.write.parallel        | 0             | 是否开启并行写入，0表示关闭，8表示8个线程写入。注意，性能提升比例并不与线程数成正比。 |
+
+   使用示例：使用SQL查询时选中一起执行。
+
+   ```
+   SET cz.sql.index.prewhere.enabled=true; -- 当前需要设置开关，后续版本会默认开启
+   SELECT id, doc, l2_distance(vec, vector(1,2,3,4)) as dist FROM some_table WHERE match_regexp(doc, '.*hello.*', map('analyzer', 'keyword')) AND l2_distance(vec, vector(1,2,3,4)) < 1000 ORDER BY dist LIMIT 100
+   ```
+
+5. **计费**
+
+   存储资源：向量索引会创建向量索引文件，该文件和数据文件都保存在对象存储中，统一计费。

+# 计算集群
+
+计算集群（Virtual-Cluster，简称：VCluster）是云器Lakehouse提供的一项核心服务，旨在为用户提供高效、可扩展的计算资源。计算集群为Lakehouse中的查询分析、ETL作业、流式分析和即席查询等任务提供必要的CPU、内存和临时存储资源。通过计算集群，用户可以在Lakehouse中执行各种复杂的数据处理任务。
+
+## 核心概念
+
+### 集群名称
+
+每个计算集群都需要一个唯一的名称，该名称在工作空间内必须唯一。集群名称一旦创建，将无法更改。在Lakehouse中，集群的完整标识由工作空间名称和计算集群名称共同构成。
+
+### 规格
+
+计算集群的规格定义了集群中每个计算副本可用的计算资源数量，以Compute Resource Unit（CRU）为单位。CRU是云器Lakehouse对IaaS计算资源算力的抽象，以便在不同云平台、不同CPU架构和规格下，均能获得一致的算力。
+
+说明：自2024年12月起，计算集群旧有从XS到5XLarge的规格代码变更为使用数字表达的规格。变更详见：[计算集群规格代码变更说明](vcluster_size_description.md)。
+
+| **类型**                         | **最小规格**（**CRU**） | **最大规格**（**CRU**） | **默认值**（**CRU**） | **步长**&#xA;（规格增减的最小单位）                                                                 |
+| ------------------------------ | ----------------- | ----------------- | ---------------- | -------------------------------------------------------------------------------------- |
+| 通用型&#xA;（GP VCluster）          | 1                 | 256               | 1                | 规格变更步长为：1CRU。&#xA;规格示例：1，2，3，4，5，6...256                                               |
+| 分析型&#xA;（AP VCluster）          | 1                 | 256               | 1                | 规格变更步长为：2的n次幂CRU。&#xA;规格示例：1，2，4，8，16，32，64，128，256                                   |
+| 同步型&#xA;（Integration VCluster） | 0.25              | 256               | 0.5              | 规格变更步长为：&#xA;有0.25 CRU和0.5 CRU两个特殊的小规格，其余步长为1 CRU。&#xA;规格示例：0.25，0.5，1，2，3，4，5，6...256 |
+
+每个集群每小时消耗的计算资源量为其CRU规格\*1小时，即单位为CRU\*时。例如规格为3 CRU的分析型计算集群，运行1小时的资源消耗为 3CRU \* 1小时=3CRU\*时。其费用也按照计算集群所在区域的“CRU\*时”的单价计算。
+
+### 集群类型
+
+计算集群分为通用型、分析型和同步型，三大类：
+
+* 通用型（GENERAL)）：适用于处理离线作业，作业之间共享计算资源，新旧作业采用公平调度方式分配计算资源。
+* 分析型(ANALYTICS)：具备多计算实例和自动弹缩功能，适合处理在线和高并发作业。当作业并发数达到上限时，后续作业将排队等待执行，确保先提交的作业优先执行。
+* 同步型(INTEGRATION)：适用于处理离线集成和实时集成任务。多个集成任务可共用一个同步型计算集群实例。超出集群计算能力的集成任务将进入队列排队。
+
+不同集群类型与下图中任务类型的对应关系如下：
+
+
+| **任务类型**            | **可使用集群类型** | **建议使用集群类型**                        |

+
+### 实例最小值
+
+仅分析型计算集群支持此属性。指计算集群初始启动时集群实例数量，默认为1 个实例。
+
+### 实例最大值
+
+仅分析型计算集群支持此属性。指计算集群可以使用的最大实例数量，默认为2 个实例。当新的查询超过当前实例的最大并发数时，将触发计算集群的自动扩容，新增一个计算集群实例。扩容计算集群实例的上限为实例最大值。
+
+### 自动停止
+
+当计算集群在自动停止配置指定的时间内无作业运行时，计算集群自动停止、释放资源，停止消耗计算费用。自动停止配置最小单位为“秒”，最小可配置为15秒。
+
+因运行不足1分钟的计算集群，将按照1分钟收费。所以当选择自动停止时间小于1分钟时，请谨慎确认，避免产生不必要的费用。1
+
+### 自动启动
+
+当有新作业提交时，若计算集群已停止，开启自动启动功能的计算集群将自动启动并执行作业。关闭该配置则指定计算集群需要手动启动。手动启动集群可参考本文中的“启动与停止集群”操作，或使用Alter Vcluster \<vcluster\_name> resume；语句。
+
+## 管理计算集群
+
+云器Lakehouse提供两种管理控制计算集群的方式：1）Web-UI方式；2）通过SQL方式。
+
+### Web-UI方式
+
+#### 查看集群信息
+
+登录Lakehouse平台，点击左侧菜单的“计算”功能，进入“计算集群”列表页面。在此页面，您可以查看当前工作空间内所有授权访问的计算集群。
+
+![](.topwrite/assets/image_1741611037239.png)
+
+点击任一集群名称，进入详情页面，您可以查看集群的作业执行情况、配置详情以及当前用户对该集群的权限。
+
+:-: ![](.topwrite/assets/image_1728532541352.png =805)
+
+#### 创建计算集群
+
+在“计算集群”列表页面，点击“新建集群”按钮，进入新建集群界面。填写集群名称、选择集群类型、配置规格等信息后，点击“创建集群”完成集群创建。新集群将在列表中显示，并在状态变为“运行中”后即可使用。
+
+:-: ![](.topwrite/assets/image_1742214451076.png =813)
+
+^
+
+**创建通用型集群**
+
+:-: ![](.topwrite/assets/image_1742216967064.png =414)
+
+如果需要处理ETL等批量类型的作业，建议创建通用型计算集群：
+
+* 在“类型”属性中选择“通用型”。
+* 在“规格”属性中，可以选择“固定”和“弹性伸缩”两种方式。“固定”意味着该集群的规格大小不会随着负载而弹缩，可以有效控制集群所消耗资源，进而控制计算成本；“弹性伸缩”意味着该集群的规格大小会随着负载而弹缩，更有利于对任务SLA有强保障需求的场景。
+
+> 注意，通用型集群的弹性伸缩是以“最快完成当前提交至计算集群的所有任务”为目的，会在当前规格满载后，立即扩容至满足所有任务需求的规格大小。该策略更倾向于效率而非成本。因此请根据成本和效率的实际需要，合理选择“固定”或“弹性伸缩”的方式，以及弹性伸缩的最大、最小规格。
+
+* 选择是否开启“自动启动”和“自动停止”，并配置合理的“自动停止”时间。推荐开启“自动启动”，以及时处理作业任务，配置“自动停止”时间为1分钟，以当作业结束时能尽快关闭计算集群，节省成本。
+
+完成上述配置后，点击“确定”即完成通用型计算集群的创建。
+
+^
+
+**创建分析型集群**
+
+:-: ![](.topwrite/assets/image_1742216902917.png =404)
+
+^
+
+如需要为即席查询或BI看板等查询分析场景提供计算资源，建议创建分析型集群：
+
+* 在“类型”属性中选择“通用型”。
+* 在“规格”属性中，选择符合业务需要的规格。规格大小通常和该计算集群要负载的请求并发数、查询数据量、查询复杂度正相关，与预期查询结果返回时间负相关。可以在创建计算集群后，通过并发测试，逐步调整至满足查询效率需要且能够取得最优成本的规格。
+* 选择是否开启“自动启动”和“自动停止”，并配置合理的“自动停止”时间。推荐开启“自动启动”，以及时处理作业任务，配置“自动停止”时间为30分钟以上，以尽量利用分析型集群的缓存加速查询结果，使终端用户获得更好的查询体验。
+* 配置“最大并发数”。最大并发数指该集群每个实例所能够支持的最大并发数，当作业并发数超过该值时，作业会开始排队或触发扩容新的实例。
+* “实例最小值”和“实例最大值”指该集群弹缩时的最小和最大实例数。当该计算集群当前所有实例的负载都达到“最大并发数”配置时，实例开始扩容，直至满足作业并发或达到“实例最大值”，实例扩容时，排队队列中的作业或新提交的作业会分配至新实例上，正在处理的作业不受影响；当该计算集群缩容一个实例仍可以满足所有并发时，开始缩容，直至缩容至能满足所有并发的最小实例数或该集群配置的“实例最小值”，实例缩容时，排队队列中的作业或新提交的作业不再分配至将要缩容的实例上，正在处理的作业不受影响，当正在处理的作业完成后，该实例完成释放。
+
+^
+
+**创建同步型集群**
+
+:-: ![](.topwrite/assets/image_1742217991159.png =411)
+
+如果需要处理离线或实时集成任务，需要创建同步型集群：
+
+* 在“类型”属性中选择“同步型”。
+* 在“规格”属性中，可以选择“固定”和“弹性伸缩”两种方式。“固定”意味着该集群的规格大小不会随着负载而弹缩，可以有效控制集群所消耗资源，进而控制计算成本；“弹性伸缩”意味着该集群的规格大小会随着负载而弹缩，更有利于对任务SLA有强保障需求的场景。
+
+> 注意，同步型集群的弹性伸缩是以“最快完成当前提交至计算集群的所有任务”为目的，会在当前规格满载后，立即扩容至满足所有任务需求的规格大小。该策略更倾向于效率而非成本。因此请根据成本和效率的实际需要，合理选择“固定”或“弹性伸缩”的方式，以及弹性伸缩的最大、最小规格。
+
+* 同步型计算集群提供了“规格预估”功能，辅助选择合适的同步型集群规格。可通过输入“任务数”和“平均任务并发数”，按照“规格=任务数 \* 平均任务并发数 \* 0.05”的公式计算出预估的集群规格。
+
+:-: ![](.topwrite/assets/image_1742218209994.png =441)
+
+* 选择是否开启“自动启动”和“自动停止”，并配置合理的“自动停止”时间。推荐开启“自动启动”，以及时处理作业任务，配置“自动停止”时间为1分钟，以当作业结束时能尽快关闭计算集群，节省成本。
+
+^
+
+#### 修改计算集群属性
+
+在集群列表中，选择相应集群，点击“操作”列的“修改”按钮，即可对集群配置进行调整。修改后的集群配置可能影响集群状态，请注意在修改规格、实例数等关键属性时，确保集群上没有正在运行的作业。
+
+:-: ![](.topwrite/assets/image_1733812147311.png =813)
+
+####
+
+#### 启动与停止计算集群
+
+在集群列表中，点击“操作”列的“启动”或“停止”按钮，即可对计算集群进行启动或停止操作。请注意，停止集群时，正在执行的作业将等待完成后集群才会停止。
+
+:-: ![](.topwrite/assets/image_1733812217836.png =813)
+
+^
+
+###
+
+#### 删除计算集群
+
+在集群列表中，点击“操作”列的“删除”按钮，即可删除指定的计算集群。删除集群前，需要先停止集群，并等待所有作业完成后才能完成删除操作。
+
+:-: ![](.topwrite/assets/image_1733812348735.png =810)
+
+###
+
+### SQL方式
+
+除了Web-UI，Lakehouse还支持使用SQL命令直接操作计算集群。具体命令和使用方法，请参考[计算资源DDL](create_cluster.md)文档。
+
+###
+
+## 计算集群配置实践
+
+#### 自动化管理计算集群
+
+计算集群实例可在停止状态下，被提交的任务唤醒，秒级启动并开始执行作业，并可在集群空闲时自动关机，以节约成本。充分利用这一特性，可使计算集群的成本尽量贴合业务的负载，大幅提高资源利用率。
+
+* 配置自动暂停和恢复：在创建或修改计算集群实例的窗口，可以找到“自动启动”和“自动停止”的配置项。通常情况下，这两个配置是配合进行配置的：打开“自动启动”，并且设置“自动停止”时间。
+* 设置合适的超时限制：计算集群的“自动停止”时间可以设置从1分钟到3小时不等。合理选择“自动停止”时间需要考虑到计算集群的启动和停止对作业带来的影响：
+* 1）对离线作业可以将“自动停止”时间设置得尽量短，例如1分钟。以便集群在完成作业后能够尽快停止运行，避免空闲时间带来的资源浪费。
+* 2）对在线查询服务则需要适当延长“自动停止”时间，例如30分钟。这样做首先可以尽量减少计算集群从“停止”状态到“启动”状态带来的查询请求延迟，保证查询体验；其次也可以尽量延长计算结果缓存的时间（针对分析型计算集群），提升查询效率。
+* 3）强烈不建议将“自动停止”时间配置到1分钟以内。由于计算集群计费是以秒级计费的，当运行时间不足60秒时会按照60秒计费。当配置自动停止时间为1分钟以内时，如果该计算集群上执行的作业运行时间非常短，可能造成1分钟内计算集群多次启动和停止，从而产生多个60秒的费用，造成费用上升。仅当对确认该集群上运行的作业时长不会造成集群1分钟内多次启停时，才可以配置自动停止时间小于1分钟。
+
+#### 合理扩大或减小计算集群规格
+
+实例规格是对虚拟集群进行垂直伸缩的选项，调整实例规格可以让单个作业获得更大的算力以提升作业性能。
+
+在实际的业务场景中，对于面向用户的数据产品往往有SLA的要求，如100并发下P99的查询延迟小于2秒。同时，也希望计算资源得到充分的利用，在满足业务需求的前提下尽可能降低资源成本。
+
+在实际业务使用中，推荐使用不同大小的计算集群规格运行查询（例如使用从8 CRU->1 CRU几种规格分别进行测试），找到集群规格尽可能小、同时性能下降不明显的资源规格。
+
+从业务负载类型、执行频率、作业并发、处理数据规模、SLA要求几个维度提供样例的资源规格设计，供参考使用：
+
+| 业务场景                      | 负载类型             | 执行频率   | 作业并发 | 处理数据规模 | VCluster类型 | 作业时延SLA               | VCluster Size |
+| ------------------------- | ---------------- | ------ | ---- | ------ | ---------- | --------------------- | ------------- |
+| ETL调度作业                   | 近实时离线处理          | 小时     | 1    | 1   TB | 通用型        | 15 分钟                 | 4             |

+
+#### 通过多计算资源实现负载隔离
+
+* 使用多个独立的计算支撑不同业务负载（Workload）。可根据周期性ELT、线上业务报表、分析师数据分析等不同需求，创建不同的计算资源并分配给不同的用户或应用使用，避免不同业务或人员资源争抢导致的SLA下降。
+  例如：
+
+* 周期性ELT任务和线上业务报表查询任务应当使用不同计算集群进行隔离，并分别使用通用型和分析型两种类型的计算集群，以充分发挥不同类型计算集群的性能特性，并且易于配置不同的自动停止时间——运行周期性ELT任务的计算集群的自动停止时间配置尽量短，比如1分钟；运行线上业务报表查询任务的计算集群自动停止时间配置稍长，比如5分钟。
+
+* 将运行大作业和小作业的计算集群进行隔离，为大作业配置较大规格的计算集群，保障大作业的运行时间，为小作业配置较小规格的计算集群避免不能跑满计算集群负载，造成资源浪费。

+
+## 基础文件管理
+
+### 🔍 文件列表查询
+
+```sql
+-- 基础列表查询
+LIST USER VOLUME;
+LIST TABLE VOLUME my_table;
+LIST VOLUME mcp_demo.data_volume;
+
+-- 子目录查询
+LIST USER VOLUME SUBDIRECTORY 'reports/2024/';
+LIST TABLE VOLUME my_table SUBDIRECTORY 'backups/';
+LIST VOLUME mcp_demo.data_volume SUBDIRECTORY 'csv_data/';
+
+-- 正则表达式过滤
+LIST USER VOLUME REGEXP = '.*\.parquet';
+LIST TABLE VOLUME my_table REGEXP = '.*backup.*';
+LIST VOLUME mcp_demo.data_volume REGEXP = '.*month=0[1-5].*';
+
+-- 组合查询：子目录+正则表达式
+LIST VOLUME mcp_demo.data_volume 
+SUBDIRECTORY 't_search_log' 
+REGEXP = '.*c000';
+```
+
+### 🗑️ 文件删除管理（REMOVE命令）
+
+```sql
+-- 删除单个文件
+REMOVE USER VOLUME FILE 'temp/data.csv';
+REMOVE TABLE VOLUME my_table FILE 'backup/old_data.parquet';
+REMOVE VOLUME my_external_vol FILE 'processed/result.json';
+
+-- 删除多个文件（需要多次执行REMOVE命令）
+-- 注意：当前版本不支持逗号分隔的多文件删除方式
+REMOVE USER VOLUME FILE 'temp/file1.csv';
+REMOVE USER VOLUME FILE 'temp/file2.csv';
+
+-- 删除整个目录（递归删除）
+REMOVE USER VOLUME SUBDIRECTORY 'temp/';
+REMOVE TABLE VOLUME my_table SUBDIRECTORY 'old_backups/';
+REMOVE VOLUME my_external_vol SUBDIRECTORY 'archive/2023/';
+
+-- ⚠️ 注意：REMOVE会同时删除实际存储中的文件，不可恢复
+```
+
+### 📁 目录操作最佳实践
+
+```sql
+-- 1. 按业务场景组织目录结构
+-- 推荐目录结构：
+-- /raw/           # 原始数据
+-- /processed/     # 处理后数据  
+-- /temp/          # 临时数据
+-- /backup/        # 备份数据
+-- /archive/       # 归档数据
+
+-- 2. 按时间分区组织
+LIST USER VOLUME REGEXP = '.*2024.*';           -- 按年份
+LIST TABLE VOLUME my_table REGEXP = '.*202405.*'; -- 按年月
+LIST VOLUME external_vol REGEXP = '.*daily_20240529.*'; -- 按日期
+
+-- 3. 按文件类型分类
+LIST USER VOLUME REGEXP = '.*\.csv';           -- CSV文件
+LIST TABLE VOLUME my_table REGEXP = '.*\.parquet'; -- Parquet文件
+LIST VOLUME external_vol REGEXP = '.*\.json';      -- JSON文件
+```
+
+### ⚠️ 文件管理注意事项
+
+1. **PUT/GET命令限制**: 只能在SQLLine等客户端中执行，Studio WEB端不支持
+2. **文件大小限制**: 单个文件不超过5GB
+3. **文件覆盖风险**: 同名文件会被自动覆盖，务必谨慎
+4. **权限依赖**: 操作权限与Volume类型相关（详见权限管理章节）
+
+***
+
+## 文件格式与压缩优化
+
+### 📦 支持的文件格式
+
+云器Lakehouse支持多种文件格式，每种格式都有其最佳使用场景：
+
+```sql
+-- CSV格式：适用于数据交换、人工可读
+-- Parquet格式：适用于分析场景、列式存储
+-- JSON格式：适用于半结构化数据（输出为JSON LINE格式）
+-- TEXT格式：适用于纯文本数据
+-- ORC格式：优化的行列混合格式
+-- BSON格式：二进制JSON格式
+```
+
+### 🗜️ 压缩格式配置
+
+> **注意**：根据验证测试，当前版本对于CSV格式的COMPRESSION参数可能存在限制。以下展示了推荐的语法：
+
+```sql
+-- Parquet导出（推荐，自带内置压缩）
+COPY INTO USER VOLUME 
+SUBDIRECTORY 'parquet_data/'
+FROM my_table
+FILE_FORMAT = (TYPE = PARQUET);  -- 自动应用最优压缩
+
+-- TEXT格式导出（纯文本）
+COPY INTO USER VOLUME 
+SUBDIRECTORY 'text_output/'
+FROM my_table
+FILE_FORMAT = (TYPE = TEXT);
+
+-- 导入时的压缩参数设置（在OPTIONS中）
+COPY INTO target_table
+FROM USER VOLUME
+USING CSV
+OPTIONS('header'='true')
+FILES ('data.csv');
+```
+
+### 🔧 文件格式参数说明
+
+```sql
+-- CSV导入时的参数设置
+COPY INTO target_table
+FROM USER VOLUME
+USING CSV
+OPTIONS(
+    'header'='true',              -- 包含表头
+    'sep'='|'                     -- 分隔符
+)
+FILES ('special_format.csv');
+```
+
+### 💡 格式选择建议
+
+| 格式               | 压缩比 | 查询性能 | 适用场景         |
+| ---------------- | --- | ---- | ------------ |
+| **Parquet** (推荐) | 高   | 最佳   | 分析查询、长期存储    |
+| **CSV**          | 中等  | 中等   | 数据交换、人工查看    |
+| **JSON**         | 中等  | 中等   | 半结构化数据、API接口 |
+| **TEXT**         | 低   | 低    | 日志文件、简单文本    |
+
+> **📋 最佳实践**：生产环境下存储分析数据优先选择Parquet格式，可减少50-80%存储空间并提升3-5倍查询性能。数据交换场景可使用CSV格式。
+
+***
+
+## 错误处理与数据质量
+
+### 🚫 错误处理策略
+
+> **注意**：根据验证测试，当前版本的ON\_ERROR参数语法可能存在限制。以下是建议的替代方法：
+
+```sql
+-- 导入错误处理
+-- 当遇到错误时，系统会默认返回详细的错误信息
+COPY INTO target_table
+FROM USER VOLUME
+USING CSV
+OPTIONS('header'='true')
+FILES ('import_data.csv');
+
+-- 对于可能的格式错误，建议先导入小样本进行验证
+COPY INTO target_table
+FROM USER VOLUME
+USING CSV
+OPTIONS('header'='true')
+FILES ('sample_data.csv');
+```
+
+### 🧹 PURGE自动清理功能
+
+PURGE功能可以在数据导入成功后自动删除源文件，节省存储空间：
+
+```sql
+-- 导入成功后自动删除源文件
+COPY INTO target_table
+FROM USER VOLUME

+## 预签名URL最佳实践
+
+### 🔗 基础URL生成
+
+```sql
+-- 为User Volume文件生成预签名URL
+SELECT GET_PRESIGNED_URL(USER VOLUME, 'data/report.csv', 3600) AS url;
+
+-- 为Table Volume文件生成预签名URL
+SELECT GET_PRESIGNED_URL(TABLE VOLUME my_table, 'backup/data.parquet', 3600) AS url;
+
+-- 为External Volume文件生成预签名URL  
+SELECT GET_PRESIGNED_URL(VOLUME mcp_demo.data_volume, 'path/file.csv', 3600) AS url;
+
+-- 为Named Volume文件生成预签名URL
+SELECT GET_PRESIGNED_URL(VOLUME my_schema.my_named_volume, 'shared/report.pdf', 7200) AS url;
+```
+
+### 🌐 外部URL控制
+
+```sql
+-- 设置强制生成外部可访问URL
+SET cz.sql.function.get.presigned.url.force.external=true;
+
+-- 生成外部URL（推荐用于分享）
+SELECT GET_PRESIGNED_URL(USER VOLUME, 'report.pdf', 7200) AS external_url;
+
+-- 批量生成URL（用于文件分享清单）
+SELECT 
+    relative_path,
+    size,
+    GET_PRESIGNED_URL(USER VOLUME, relative_path, 
+        CASE 
+            WHEN relative_path LIKE '%temp%' THEN 1800      -- 临时文件30分钟
+            WHEN relative_path LIKE '%archive%' THEN 86400  -- 归档文件24小时
+            ELSE 3600                                       -- 默认1小时
+        END
+    ) AS access_url
+FROM (SHOW USER VOLUME DIRECTORY)
+WHERE relative_path LIKE '%.csv';
+```
+
+### ⏰ 有效期管理策略
+
+```sql
+-- 短期访问（30分钟）- 适用于临时下载
+SELECT GET_PRESIGNED_URL(USER VOLUME, 'temp.csv', 1800) AS short_url;
+
+-- 标准访问（1小时）- 适用于常规操作
+SELECT GET_PRESIGNED_URL(USER VOLUME, 'data.csv', 3600) AS standard_url;
+
+-- 长期访问（12小时）- 适用于大文件下载
+SELECT GET_PRESIGNED_URL(USER VOLUME, 'large_archive.zip', 43200) AS long_url;
+
+-- 超长期访问（7天）- 适用于跨时区协作
+SELECT GET_PRESIGNED_URL(USER VOLUME, 'shared_report.xlsx', 604800) AS week_url;
+```
+
+### 🔐 安全最佳实践
+
+1. **最小权限原则**: 设置尽可能短的有效期
+2. **访问记录**: 生成URL时记录访问目的和有效期
+3. **定期清理**: 定期清理过期的预签名URL记录
+4. **监控异常**: 监控URL异常访问模式
+5. **外部访问控制**: 仅在必要时启用外部访问
+
+> **📋 最佳实践**：根据数据敏感程度分级设置URL有效期：公开数据≤7天，内部数据≤24小时，敏感数据≤1小时。

+## PIPE管道自动化
+
+### 🔧 前提条件与环境准备
+
+```sql
+-- 1. 确认Virtual Cluster状态
+SHOW VCLUSTERS;
+
+-- 2. 启动Virtual Cluster（如需要）
+ALTER VCLUSTER DEFAULT RESUME;
+
+-- 3. 确认使用External Volume（仅External Volume支持PIPE）
+SHOW VOLUMES;
+DESC VOLUME schema_name.volume_name;
+```
+
+### 🚰 创建PIPE管道
+
+```sql
+-- 创建目标表

+```
+
+### 📊 PIPE管理与监控
+
+```sql
+-- 查看所有PIPE
+SHOW PIPES;
+
+-- 查看PIPE详细信息
+DESC PIPE data_auto_import_pipe;
+
+-- 暂停PIPE（正确语法）
+ALTER PIPE data_auto_import_pipe SET PIPE_EXECUTION_PAUSED = true;
+
+-- 恢复PIPE（正确语法）
+ALTER PIPE data_auto_import_pipe SET PIPE_EXECUTION_PAUSED = false;
+
+-- 删除PIPE
+DROP PIPE IF EXISTS data_auto_import_pipe;
+```
+
+### ⚠️ PIPE使用限制与注意事项
+
+1. **仅支持External Volume**: User Volume和Table Volume不支持PIPE监控
+2. **新文件监控**: PIPE用于监控新增文件，不能指定现有文件
+3. **Virtual Cluster依赖**: 需要可用的Virtual Cluster执行
+4. **权限要求**: 需要对Volume和目标表的相应权限
+5. **性能考虑**: 合理设置批处理参数避免资源浪费
+
+> **🔄 自动化建议**：对于需要实时/准实时导入的数据流，推荐使用PIPE配合External Volume，可实现全自动的数据摄取流程。

+
+## 权限管理与安全控制
+
+### 🔐 Volume权限体系
+
+不同类型的Volume有不同的权限管理模式：
+
+```sql
+-- User Volume权限（用户默认拥有管理权限）
+-- 无需额外授权，用户对自己的User Volume拥有完全控制权
+
+-- Table Volume权限（与表权限联动）
+-- 需要对应表的权限才能操作Table Volume：
+-- SELECT 权限 → SHOW/LIST/GET 操作
+-- INSERT/UPDATE/DELETE 权限 → PUT/REMOVE 操作
+
+-- External Volume权限（需要显式授权）
+GRANT READ VOLUME ON VOLUME schema_name.external_volume_name TO USER username;
+GRANT WRITE VOLUME ON VOLUME schema_name.external_volume_name TO USER username;
+GRANT ALL ON VOLUME schema_name.external_volume_name TO ROLE data_engineer;
+```
+
+### 👥 权限管理最佳实践
+
+```sql
+-- 创建角色化权限管理
+CREATE ROLE data_reader;
+CREATE ROLE data_writer;
+CREATE ROLE data_admin;
+
+-- 批量权限授予
+GRANT READ VOLUME ON VOLUME schema_name.shared_volume TO ROLE data_reader;
+GRANT READ VOLUME, WRITE VOLUME ON VOLUME schema_name.shared_volume TO ROLE data_writer;
+GRANT ALL ON VOLUME schema_name.shared_volume TO ROLE data_admin;
+
+-- 用户角色分配
+GRANT ROLE data_reader TO USER analyst_team;
+GRANT ROLE data_writer TO USER etl_team;
+GRANT ROLE data_admin TO USER admin_user;
+
+-- 查看Volume权限
+SHOW GRANTS ON VOLUME schema_name.volume_name;
+
+-- 查看用户权限
+SHOW GRANTS TO USER username;
+
+-- 回收权限
+REVOKE WRITE VOLUME ON VOLUME schema_name.volume_name FROM USER username;
+```
+
+### 🛡️ 安全配置建议
+
+```sql
+-- 预签名URL安全设置
+SET cz.sql.function.get.presigned.url.force.external=true;  -- 仅在需要时启用
+
+-- 定期权限审计
+SHOW GRANTS ON VOLUME schema_name.volume_name;
+```
+
+> **🔒 安全原则**：对于生产环境，建议采用基于角色的权限管理模式，将Volume权限与用户角色绑定，避免直接对用户授权，便于后期权限维护。

+
+### 🌐 网络传输成本优化
+
+1. **同Region部署**: 确保Lakehouse与Volume存储在同一区域
+2. **内网传输**: 同云厂商同Region使用内网传输，避免公网费用
+3. **批量操作**: 批量导入导出减少网络请求次数
+
+### ⚡ 计算资源优化
+
+```sql
+-- 选择合适的计算集群类型
+-- 批量数据处理：建议使用通用型计算集群 (GENERAL PURPOSE VIRTUAL CLUSTER)
+-- 实时查询：使用分析型计算集群
+
+-- 检查当前集群配置
+SHOW VCLUSTERS;
+
+-- 优化建议：
+-- 1. 导入数据时使用通用型集群
+-- 2. 启用自动小文件合并（仅通用型集群支持）
+-- 3. 合理设置PIPE批处理参数
+```
+
+### 📊 成本监控建议
+
+1. **定期存储审计**: 每月分析存储使用情况
+2. **文件生命周期管理**: 设置数据归档和清理策略
+3. **网络传输监控**: 监控跨Region数据传输量
+
+> **💲 成本控制目标**：转换到Parquet格式可减少40-60%存储成本；合理的生命周期管理可减少20-30%的存储开销；使用内网传输可减少90%以上的网络传输费用。

+-- 解决方案3：限制返回结果（使用DIRECTORY函数）
+SELECT relative_path, size 
+FROM DIRECTORY(VOLUME mcp_demo.data_volume) 
+WHERE relative_path LIKE 'current_month/%'
+LIMIT 100;
+```
+
+**问题**: 查询性能差，小文件过多
+
+```sql
+-- 解决方案1：定期合并小文件
+-- 使用导入导出方式合并文件
+
+-- 解决方案2：使用合适的文件格式
+-- 推荐使用Parquet格式存储分析数据
+```
+
+### ❓ 数据质量问题
+
+**问题**: 导入数据格式错误
+
+```sql
+-- 解决方案：验证文件格式和表结构
+-- 1. 首先查看文件内容
+LIST USER VOLUME REGEXP = '.*\.csv';
+
+-- 2. 使用小样本测试导入
+COPY INTO test_target
+FROM USER VOLUME
+USING CSV
+OPTIONS('header'='true')
+FILES ('sample.csv');
+```
+
+**问题**: 文件意外被删除
+
+```sql
+-- 预防方案：谨慎使用PURGE参数
+COPY INTO target_table
+FROM VOLUME my_volume
+USING CSV
+PURGE = FALSE;  -- 保留源文件
+
+-- 建议：重要数据使用备份策略
+COPY INTO TABLE VOLUME backup_table 
+SUBDIRECTORY 'daily_backup/'
+FROM source_table
+FILE_FORMAT = (TYPE = PARQUET);

+## 窗口函数（Window Functions）
+
+窗口函数（Window Functions）是一种强大的SQL函数，它允许用户在一个查询中对数据集进行分组计算。与传统的聚合函数不同，窗口函数可以对每一行数据进行计算，同时保留原始数据的详细信息。窗口函数在数据分析、报表生成等场景中具有广泛的应用，例如计算排名、累计和、移动平均等。
+
+## 窗口函数的基本语法
+
+窗口函数的基本语法如下：
+
+```SQL
+<window_function> OVER (
+    [PARTITION BY <partition_expression>]
+    [ORDER BY <order_expression>]
+)
+```
+
+* `<window_function>`：指定要使用的窗口函数，如`ROW_NUMBER()`、`RANK()`、`SUM()`等。
+* `PARTITION BY`：将数据集划分为不同的分区，每个分区是一个独立的计算范围。
+* `ORDER BY`：在每个分区内对数据进行排序，影响部分窗口函数的计算结果。
+
+## 窗口函数的分类
+
+根据功能和返回值类型，窗口函数可分为以下几类：
+
+1.  **排名函数（Ranking Functions）**：对数据进行排名，返回表示相对位置的整数值。常用排名函数包括`ROW_NUMBER()`、`RANK()`、`DENSE_RANK()`、`PERCENT_RANK()`、`CUME_DIST()`、`NTILE()`等。
+2.  **聚合函数（Aggregate Functions）**：对数据进行聚合计算，返回表示整体特征的值。Lakehouse支持所有标准的聚合函数。
+3.  **分析函数（Analytic Functions）**：对数据进行分析计算，返回表示数据特征的值。常用分析函数包括`FIRST_VALUE()`、`LAST_VALUE()`、`LAG()`、`LEAD()`、`NTH_VALUE()`、`CUME_DIST()`等。
+
+## 窗口函数的使用示例
+
+以下是一些使用窗口函数的SQL查询示例及其输出结果。假设我们有一个名为 `sales` 的表，它包含了每个月的销售额和利润率数据，如下所示：
+
+```SQL
+CREATE    TABLE sales (MONTH int, sales int, profit double);
+INSERT    INTO sales (MONTH, sales, profit)
+VALUES    (1, 100, 0.1),
+          (2, 120, 0.15),
+          (3, 80, 0.05),
+          (4, 150, 0.2),
+          (5, 90, 0.1),
+          (6, 110, 0.12);
+```
+
+### Ranking Functions
+
+* 查询：使用`ROW_NUMBER()`函数对销售额进行降序排名。
+
+```SQL
+SELECT month, sales, ROW_NUMBER() OVER (ORDER BY sales DESC) AS rank
+FROM sales;
++-------+-------+------+

+# Window Frame
+
+Window Frame 是在使用窗口函数时定义的一个子集，用于限制窗口函数的计算范围，只对窗口框架中的数据进行计算。通过窗口框架，可以更加精确地控制窗口函数的计算方式和结果。以下是窗口框架的详细说明和使用示例。
+
+## Window Frame语法
+
+在使用窗口函数时，可以通过 `OVER` 子句定义窗口框架，语法如下：
+
+```SQL
+<window_function> OVER (
+    [PARTITION BY <partition_expression>]
+    [ORDER BY <order_expression>]
+    [frame_clause>]
+)
+```
+
+其中，`<window_function>` 表示要使用的窗口函数名称，例如 `ROW_NUMBER()`、`RANK()`、`SUM()` 等。`PARTITION BY` 子句用于将数据分组，每个分组称为一个分区（partition）。`ORDER BY` 子句用于在每个分区中对数据进行排序，这将影响某些窗口函数的结果，如 `ROW_NUMBER()`、`RANK()` 等。`frame_clause` 用于定义窗口框架的范围，有两种形式：`ROWS frame` 和 `RANGE frame`。
+
+### ROWS frame
+
+`ROWS frame` 是基于行的窗口框架，用于指定窗口框架中包含的行数或位置。其语法如下：
+
+```SQL
+ROWS BETWEEN <start_boundary> AND <end_boundary>
+```
+
+`<start_boundary>` 和 `<end_boundary>` 用于定义窗口框架的起始和结束边界，可以是以下值之一：
+
+- `UNBOUNDED PRECEDING`：从分区的第一行开始。
+- `UNBOUNDED FOLLOWING`：到分区的最后一行结束。
+- `CURRENT ROW`：当前行。
+- `<offset> PRECEDING`：当前行之前的第`<offset>`行，`<offset>`为非负整数。
+- `<offset> FOLLOWING`：当前行之后的第`<offset>`行，`<offset>`为非负整数。
+
+### RANGE frame
+
+`RANGE frame` 是基于值的窗口框架，用于指定窗口框架中包含的行的值的范围。其语法如下：
+
+```SQL
+RANGE BETWEEN <start_boundary> AND <end_boundary>
+```
+
+`<start_boundary>` 和 `<end_boundary>` 用于定义窗口框架的起始和结束边界，可以是以下值之一：
+
+- `UNBOUNDED PRECEDING`：从分区中最小值开始。
+- `UNBOUNDED FOLLOWING`：到分区中最大值结束。
+- `CURRENT ROW`：当前行的值。
+- `<value> PRECEDING`：当前行的值减去`<value>`，`<value>`为非负数。
+- `<value> FOLLOWING`：当前行的值加上`<value>`，`<value>`为非负数。
+
+## Window Frame的使用示例
+
+以下是一些使用 Window Frame 的 SQL 查询示例，以及它们的输出结果。假设我们有一个名为 sales 的表，它包含了每个月的销售额和利润率的数据，如下所示：
+
+
+
+| month | sales | profit |
+| ----- | ----- | ------ |
+| 1     | 100   | 0.1    |
+| 2     | 120   | 0.15   |
+| 3     | 80    | 0.05   |
+| 4     | 150   | 0.2    |
+| 5     | 90    | 0.1    |
+| 6     | 110   | 0.12   |
+
+
+
+### ROWS frame
+
+* 查询：使用 `SUM()` 函数和 `ROWS frame` 计算每个月的销售额与前两个月和后两个月的销售额的总和。
+
+```SQL
+SELECT month, sales, SUM(sales) OVER (ORDER BY month ROWS BETWEEN 2 PRECEDING AND 2 FOLLOWING) AS sum_sales
+FROM sales;
+
++-------+-------+-----------+
+| month | sales | sum_sales |
++-------+-------+-----------+
+| 1     | 100   | 300       |
+| 2     | 120   | 450       |
+| 3     | 80    | 540       |
+| 4     | 150   | 550       |
+| 5     | 90    | 430       |
+| 6     | 110   | 350       |
++-------+-------+-----------+
+```
+
+* 查询：使用 `AVG()` 函数和 `ROWS frame` 计算每个月的利润率与前一个月和后一个月的利润率的平均值。
+
+```SQL
+SELECT month, profit, AVG(profit) OVER (ORDER BY month ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING) AS avg_profit
+FROM sales;
++-------+--------+---------------------+
+| month | profit |     avg_profit      |
++-------+--------+---------------------+
+| 1     | 0.1    | 0.125               |
+| 2     | 0.15   | 0.09999999999999999 |
+| 3     | 0.05   | 0.13333333333333333 |
+| 4     | 0.2    | 0.11666666666666665 |
+| 5     | 0.1    | 0.14                |
+| 6     | 0.12   | 0.11                |
++-------+--------+---------------------+
+```
+
+### RANGE frame
+
+* 查询：使用 `COUNT()` 函数和 `RANGE frame` 计算每个月的销售额在全年销售额中的分布，即有多少个月的销售额与当前月的销售额相差不超过 10。
+
+```SQL
+SELECT month, sales, COUNT(*) OVER (ORDER BY sales RANGE BETWEEN 10 PRECEDING AND 10 FOLLOWING) AS count_sales
+FROM sales;
++-------+-------+-------------+
+| month | sales | count_sales |
++-------+-------+-------------+
+| 3     | 80    | 2           |
+| 5     | 90    | 3           |
+| 1     | 100   | 3           |
+| 6     | 110   | 3           |
+| 2     | 120   | 2           |
+| 4     | 150   | 1           |
++-------+-------+-------------+
+```
+
+* 查询：使用 `MAX()` 函数和 `RANGE frame` 计算每个月的利润率与前一个月和后一个月的利润率的最大值。
+
+```SQL
+SELECT month, profit, MAX(profit) OVER (ORDER BY month RANGE BETWEEN 1 PRECEDING AND 1 FOLLOWING) AS max_profit
+FROM sales;
++-------+--------+------------+
+| month | profit | max_profit |
++-------+--------+------------+
+| 1     | 0.1    | 0.15       |
+| 2     | 0.15   | 0.15       |
+| 3     | 0.05   | 0.2        |

+# 使用Lakehouse计算集群
+
+## 一、概述：为什么需要“计算集群”？
+
+在云器Lakehouse中，无论是执行离线/实时数据集成，进行复杂的ETL任务，还是进行实时/离线的交互式查询，都需要使用Lakehouse提供的计算集群（Virtual Cluster，简称Vcluster）。计算集群支持：
+
+* **按需启动与停止**：无查询或作业时可自动停止，避免资源闲置带来的成本浪费；有新作业或查询到来时可自动启动，保障及时处理。
+* **灵活规格选择**：可根据作业负载和并发度，快速“垂直扩容”或“水平扩展”。
+* **多种使用方式**：可通过Web界面或SQL DDL命令方式完成集群创建、启动、停止、调整大小、权限管理等操作。
+
+这份文档将结合**Lakehouse计算集群**的特性与操作方法，结合实际应用场景给出一些应用示例和最佳实践。
+
+## 二、核心概念与主要功能
+
+### 1. 集群名称
+
+每个云器计算集群都有唯一名称，在其所在的工作空间下不可重复。计算集群一旦创建，名称不可更改。
+
+### 2. 规格
+
+在Lakehouse中，规格以 “CRU（Compute Resource Unit）”为单位，如（1CRU，2CRU，4CRU...直至256CRU）。根据需求可选择**通用型/分析型/同步型**集群，并配置对应的集群大小。
+
+**注意**：更大规格的集群意味着更高的负载能力和查询性能，同时也会产生更高的成本。可根据业务负载和成本预期，在使用过程中调整、优化集群规格。
+
+### 3. 集群类型
+
+Lakehouse计算集群分为通用型（General Purpose 简称：GP）、分析型（Analytics Purpose，简称AP）和同步型（Integration Purpose，简称：Integration）。
+
+* 通用型（GP）：适合离线作业或综合场景，同一计算集群中的作业资源共享、公平调度。可自动弹缩规格大小（纵向扩缩容）。
+* 分析型（AP）：适合ad-hoc和高并发在线作业场景，同一计算集群中的作业独占资源，根据作业先后排队执行。可根据并发负载自动弹缩副本数（横向扩缩容）。
+* 同步型（Integration）：适合实时/离线数据集成等同步任务，多个集成任务可共用一个实例，可根据负载自动弹缩规格大小（纵向扩缩容）。
+
+### 4. 自动启动 & 自动停止
+
+**自动启动**：当有新的查询作业提交到集群时，若集群处于“停止运行（suspended）”状态，则自动启动以执行任务。
+
+**自动停止**：在集群配置的自动停止时间内无作业/查询任务后，集群自动停止并释放计算资源，不再产生计费。
+
+### 5. 多实例弹缩
+
+Lakehouse的分析型计算集群可设定“实例最小值”和“实例最大值”，在并发请求高时自动加实例，并发请求下降后自动回收实例，满足查询业务需求的同时，节省资源成本。
+
+### 6. 计费方式
+
+按照计算集群的实际运行时间计费，精确到秒，最小计费周期1分钟。通过合理设置计算集群规格以及自动停止、自动启动等策略，可有效节省计算成本。
+
+## 三、常见使用场景与使用示例
+
+### 场景 1：离线ETL作业负载
+
+**需求**：每天或每小时执行数据清洗/转换，数据规模较大，耗时几十分钟到数小时，但在作业空闲期不希望一直空耗计算集群成本。
+**解决方案**：
+
+1\. 创建通用型计算集群
+
+在需要执行ETL作业的工作空间内，创建一个通用型计算集群。根据数据量和作业完成预期配置集群规格大小，可参考[计算集群](virtual-cluster.md)中的下表进行估算和配置：
+
+| 业务场景    | 负载类型    | 执行频率 | 作业并发 | 处理数据规模 | VCluster类型 | 作业时延SLA | VCluster 规格 |
+| ------- | ------- | ---- | ---- | ------ | ---------- | ------- | ----------- |
+| ETL调度作业 | 近实时离线处理 | 小时   | 1    | 1   TB | 通用型        | 15 分钟   | 4           |
+| ETL调度作业 | T+1离线处理 | 天    | 1    | 10 TB  | 通用型        | 4 小时    | 8           |
+
+假设需要处理的数据为10TB，预期4小时内需要完成。则需要创建一个规格为8 CRU的通用型计算集群。
+
+2\. 配置自动停止时间设置为1分钟，确保作业结束后能及时释放资源。
+
+3\. 开启“自动启动”配置，当每次ETL调度任务启动时，能够自动拉起该计算集群。
+
+:-: ![](.topwrite/assets/image_1739274962311.png =514)
+
+4\. 在ETL任务（ETL\_task\_demo）的调度配置中，将任务执行的计算集群配置为上一步设置的ETL集群。更多调度配置的操作可参考[任务开发与调度](taskdevelop.md)文档中的相关内容。
+
+:-: ![](.topwrite/assets/image_1739276187369.png =791)
+
+***
+
+**效果**：
+
+1\. 当ETL任务（ETL\_task\_demo）开始执行时，通用型计算集群ETL 会自动启动。
+
+2\. 当ETL任务（ETL\_task\_demo）执行结束后，通用型计算集群ETL会在空闲1分钟后自动关闭。
+
+^
+
+### 场景 2：在线报表+实时查询
+
+**需求**：每天工作时段，多个业务人员/分析师同时开始通过APP或BI进行业务查询，要求查询结果返回的延迟低、等待队列短。且为了提高资源使用效率，希望计算集群的资源消耗能够随着业务人员使用的规模动态弹缩，在无业务时能够自动关闭集群，节省成本。
+**解决方案**：
+
+1\. 创建分析型计算集群，并设置：
+
+实例规格为**4 CRU**；
+
+实例最小值为**1**，最大值为**10**；
+
+每实例的最大并发数为**8**；
+
+开启**自动启动**；
+
+自动停止时间为**30 分钟**。
+
+这样预期100GiB数据量的复杂查询，能在3秒内返回查询结果。计算集群运行时，最小规模下可以支持8并发，最大可以支持80并发的查询。超过80并发时，新增的并发请求会开始排队。超过30分钟空闲后，该计算集群将自动关闭，停止产生计算成本。关机时间延长至30分钟而非1分钟，可尽量减少频繁重启对查询体验的影响，也能保留缓存更快响应后续查询，兼顾成本和查询效果。
+
+:-: ![](.topwrite/assets/image_1743422670370.png =469)
+
+^
+
+2\. 在APP或BI链接Lakehouse执行查询作业时，配置使用ANALYTICS\_BI这个计算集群执行查询任务。以JDBC为例，连接串如下：
+
+```SQL
+jdbc:clickzetta://<your_instance_name>.<region_id>.api.clickzetta.com/<your_workspace>?username=<your_username>&password=<your_password>&virtualCluster=ANALYTICS_BI&schema=public
+```
+
+以virtualCluster=ANALYTICS\_BI参数指定执行查询任务的计算集群为ANALYTICS\_BI。
+
+**效果**：
+
+实时查询处理效率高，当用户查询量激增时，会自动扩容新实例，避免排队。保证高并发下依然有良好性能。空闲时则缩容节省成本。
+
+^
+
+### 场景 3：临时分析/数据探索
+
+**需求**：数据科学家对大规模数据做探索性分析，包括反复多表Join和高级聚合。需要能够在复杂查询时快速返回查询结果。
+**解决方案**：
+
+1\. 创建一个**大规格的分析型计算**集群，如16 CRU，提升计算并行度，缩短查询时间。实例最小值1，实例最大值2，以控制成本。
+
+:-: ![](.topwrite/assets/image_1739326621174.png =378)
+
+2\. 分析阶段可**关闭自动停止**或将自动停止时间设置成30分钟以上，保留缓存，以在反复查询时大幅提升速度。
+
+:-: ![](.topwrite/assets/image_1739326785003.png =692)
+
+^
+
+:-: ![](.topwrite/assets/image_1739327118802.png =384)
+
+3\. 分析结束后手动停止或重新缩短自动暂停时长至1分钟，以节约成本。
+
+:-: ![](.topwrite/assets/image_1739327178912.png =383)
+
+4\. 若使用中发现性能不足，可随时“手动调整”计算规格，以获得更好的查询性能。
+
+:-: ![](.topwrite/assets/image_1739327260338.png =391)
+
+**效果**：
+
+* 大规格的分析型计算集群，对大批量、复杂SQL的处理更快，分析周期更短。
+* 无需一直占用大规格资源，可随时手动调整集群规格和自动启停时间，而不影响正在进行的分析作业。
+
+^
+
+### 场景 4：多任务隔离
+
+:-: **需求**：同一部门里既有周期性ELT任务，也有Ad-Hoc分析，还有在线报表请求，希望相互之间资源不互抢、资源不浪费。
+**解决方案**：
+![](.topwrite/assets/image_1739329227325.png =709)
+
+1. 创建多个集群：
+   * **ETL专用集群**：使用通用型计算集群，根据业务使用需要，配置符合作业SLA预期的规格，自动暂停时间较短，以便作业执行完成后及时关闭集群，降低费用。可以创建多个ETL专用集群，将拥有不同SLA保障需求的ETL任务分配到不同的集群上执行，避免多个ETL任务在同一集群内争抢资源，影响重要任务的SLA。
+   * **在线报表集群**：使用分析型计算集群，启用多实例模式，使计算集群可随并发数增减而自动扩缩容，并适当延长自动停止的时间，以利用缓存提高响应速度，提供稳定的在线服务。
+   * **Ad-Hoc 分析集群**：使用分析型计算集群，配置较大规格，为复杂查询提供更好的查询性能。根据实际查询需要，在使用过程中手动调整集群规格。配置较长的自动停止时间，以保留缓存，进一步提升查询性能。
+2. 为不同的调度任务、分析查询、在线报表配置各自专用的集群，隔离不同任务的负载。
+
+**效果**：
+
+* 工作负载之间互不干扰，同时实现资源利用最大化。
+* 不同场景的SLA都能得到保障，避免“一个大作业拖慢其他全部查询”或“在线查询挤占离线任务”的情况。

+# 了解和使用Result Cache
+
+## 简介
+
+云器Lakehouse使用缓存技术来加速查询性能和效率。平台提供了三种类型的Cache来提高查询性能。
+
+1. 查询结果缓存（ Result Cache ）
+2. 元数据缓存（Metadata Cache ）
+3. 虚拟集群本地缓存（Virtual Cluster Local Disk Cache）
+
+![](.topwrite/assets/image_1713780513737.png)
+
+其中：
+
+* 元数据缓存和查询结果缓存服务从属于服务层，可在工作空间内共享。
+* 虚拟集群缓存本地缓存保存在集群本地节点，仅在使用指定虚拟集群时可以使用其本地缓存。
+
+本文中将介绍缓存的工作原理、及它们的使用方式。
+
+## 结果缓存
+
+在 云器Lakehouse 中执行查询时，会自动将符合一定条件的查询结果将保留一段时间，结果会在时间段结束后清除。这部分临时存储的的查询结果称为查询结果缓存。
+
+Result Cache需要满足以下条件才能被复用：
+
+* 查询中使用的表的基础数据不改变。如果查询中使用的任何表中的数据发生更改，则无法使用结果缓存；
+* 查询中没有包含对视图的查询。如果查询对象中包含视图，不支持保留查询结果缓存；
+* 新发起的SQL查询语句在语法上能够和先前执行过的查询精确匹配；
+* 查询中不包含非确定性函数（例如：CURRENT\_TIMESTAMP()）、用户定义函数 (UDF) ；
+* 先前的Result Cache未过期删除。
+
+## 结果缓存的过期周期
+
+结果缓存成功后，默认保留周期为24小时。
+
+在 24小时内运行使用查询结果缓存的后续查询，则结果缓存过期时间将额外延长 24 小时。否则，24小时后，查询结果缓存将被清除。
+
+## 启用与禁用结果缓存
+
+使用 cz.sql.enable.shortcut.result.cache 参数在 SESSION 级别启用或禁用，如下所示。
+
+```Python
+--开启结果缓存
+set cz.sql.enable.shortcut.result.cache=true;
+
+--关闭结果缓存
+set cz.sql.enable.shortcut.result.cache=false;
+```
+
+注：当前（2024年04月）Lakehouse版本的Result Cache功能处于公测阶段、未默认开启，之后版本将默认打开。
+
+## 约束与限制
+
+缓存保留周期：24小时
+
+单个工作空间支持缓存的作业数量上限：10万
+
+结果缓存大小限制：无限制。小于等于10MB的结果将缓存在管控层内存Cache，超过10MB的结果将持久化在存储层（对象存储文件）。
+
+不支持非确定性函数、UDF查询结果的结果缓存
+
+## 结果缓存演示
+
+为了演示查询结果缓存，首先启结果缓存并在云器Lakehouse中执行一个SQL查询。然后重新运行相同的查询来验证新查询是否重用了结果缓存实现加速。
+
+```Python
+ --开启结果缓存
+set cz.sql.enable.shortcut.result.cache=true;
+
+ select
+        l_returnflag,
+        l_linestatus,
+        sum(l_quantity) as sum_qty,
+        sum(l_extendedprice) as sum_base_price,
+        sum(l_extendedprice * (1 - l_discount)) as sum_disc_price,
+        sum(l_extendedprice * (1 - l_discount) * (1 + l_tax)) as sum_charge,

+# WorkSpace（工作空间）
+
+WorkSpace（工作空间）是云器Lakehouse中用于组织和隔离资源对象（如数据对象、计算资源和用户等）的基本单元。它提供了配套的数据开发能力，包括数据集成、数据开发和数据运维等。通过使用工作空间，您可以更好地管理和控制Lakehouse中的资源和数据。
+
+## 工作空间列表
+
+登录云器Lakehouse并进入Lakehouse实例后，您可以在左侧菜单的“管理”页面中查看工作空间列表。一个服务实例下可以创建多个工作空间，它们之间默认相互隔离。用户需要加入工作空间后，才能使用其中的数据和计算资源。不同工作空间内的数据对象（如Schema、Table和View等）可以通过跨工作空间授权的方式实现数据共享。
+
+![工作空间列表截图](.topwrite/assets/image_1690451948979.png)
+
+## 创建工作空间
+
+要创建新的工作空间，请点击工作空间列表右侧的“新建”按钮。创建工作空间的用户将会默认获得该工作空间的“空间管理员”（workspace\_admin）角色，拥有使用和管理该工作空间下所有资源对象的权限，并可以管理空间内的成员。
+
+![创建工作空间截图](.topwrite/assets/image_1690452024663.png =312)
+
+## 加入工作空间
+
+只有加入工作空间的用户才能被授予相应的角色和权限，进而使用工作空间内的计算和数据资源。一个账户新建用户后，该用户初始并未加入任何工作空间，因此不具备任何工作空间的访问和使用权限。
+
+具备“空间管理员”角色的用户可以将其他用户添加到工作空间中，以便进一步授予角色和权限。空间管理员可以在“管理”-“工作空间”中点击工作空间名称进入工作空间的详情页，对工作空间中的用户进行“添加用户”和“移除用户”操作。
+
+![添加用户截图](.topwrite/assets/image_1690457600615.png)
+
+请注意，当您将用户添加到工作空间后，该用户仅加入了指定的工作空间，但尚未具备任何权限。您需要通过授予工作空间角色或权限，才能使其使用工作空间内的资源。
+
+一个用户可以同时加入多个工作空间。一个工作空间内至少需要有一名用户。
+
+## 工作空间角色
+
+为了方便快速授权，系统在每个工作空间内预设了以下空间级别的角色：
+
+| 角色名称 | 角色代码 | 角色默认权限 |
+| :--- | :--- | :--- |
+| 空间管理员 | `workspace_admin` | 拥有管理空间成员、角色、开发任务、运维中心、任务实例、空间内数据和计算集群等所有权限点的权限。 |
+| 空间成员 | `workspace_user` | 可查看空间成员、角色、开发任务、运维中心、任务实例等，但不能访问空间内数据和计算集群。 |
+| 开发人员 | `workspace_dev` | 可管理开发任务、运维中心、任务实例等，并拥有空间内数据的全部权限以及计算集群的使用权限。 |
+
+工作空间的创建者默认被授予“空间管理员”角色。其他用户在加入工作空间时，不会默认获得任何角色。一个用户可以同时被授予多个角色，其实际权限是这些角色权限的并集。一个角色可以同时授予多个用户。
+
+至少需要授予一名用户“空间管理员”角色。实例级别角色的权限与工作空间内角色的权限不存在重叠。所有工作空间内的资源均由工作空间级别的角色进行管理。用户即使被授予实例级别的任何角色，也不会直接拥有操作工作空间内对象的权限。

+# LAKEHOUSE INFORMATION\_SCHEMA元数据视图服务介绍
+
+LAKEHOUSE提供了工作空间级别的INFORMATION\_SCHEMA元数据视图服务，通过INFORMATION\_SCHEMA可查看当前空间的元数据信息及作业历史等信息。INFORMATION\_SCHEMA基于ANSI SQL-92标准设计，并扩展了云器LAKEHOUSE特有的字段和视图。它随LAKEHOUSE空间创建而默认提供，您可从中查看关心的元数据视图。
+
+## 使用说明
+
+* 视图当前阶段会存在延时15分钟左右，JOB\_HISTORY、MATERIALIZED\_VIEW刷新视图保留60天记录。
+* 最新的在线元数据信息可通过 SHOW 命令查看，例如：SHOW TABLES、SHOW JOBS 等命令将返回实时元数据信息。
+* INFORMATION\_SCHEMA下的视图均为只读，不可修改、删除。
+* 视图字段根据功能演进可能发生变化。在周期任务中使用视图时应避免使用SELECT \*直接查询所有字段，强烈建议使用SELECT COLUMN\_NAME方式选择具体需要的字段进行查询，避免视图字段发生变更时导致周期任务出错。
+
+## 权限要求
+
+* 具备workspace\_admin角色
+
+## 使用示例
+
+获取当前空间的所有表信息：
+
+```SQL
+SELECT * FROM information_schema.tables;
+```
+
+获取当前空间的所有作业信息：
+
+```SQL
+SELECT * FROM information_schema.job_history;
+```
+
+获取当前空间的所有物化视图（Materialized View）信息：
+
+```SQL
+SELECT * FROM information_schema.materialized_views;
+```
+
+## 授权操作
+
+* 由workspace\_admin角色授权的角色或用户
+
+授权给某个角色：
+
+```SQL
+GRANT ALL ON ALL VIEWS IN SCHEMA information_schema TO ROLE <role_name>;
+```
+
+授权给某个用户：
+
+```SQL
+GRANT ALL ON ALL VIEWS IN SCHEMA information_schema TO USER <user_name>;
+```
+
+## 注意事项
+
+* 请确保您已经具备了相应的权限要求，否则无法使用INFORMATION\_SCHEMA元数据视图服务。
+* 在使用INFORMATION\_SCHEMA时，请注意只读的特性，不可对视图进行修改和删除操作。
+* 请在周期任务中使用具体需要的字段进行查询，避免使用SELECT \*查询所有字段，以免因视图字段变更导致周期任务出错。

Subject: [PATCH 024/521] feat(clickzetta-sdk): align token refresh, lh_code
 errors, and type coercion with Python connector
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add mutex coalescing to getToken() to prevent thundering-herd logins;
  forceRefreshToken() reuses the same pendingFetch promise.
- Pipe ConnectionConfig through ClientOptions; on 401, the HTTP core
  auto-refreshes and retries with the new token (opt-in, back-compat).
- Unify request/requestRaw on a single doRequest() core and switch
  RETRY_DELAYS to exponential backoff with jitter (retryDelayMs()).
- Introduce lh_code constants and retry predicates (isRetryableErrorCode,
  shouldResubmitWithNewJobId, isFatalErrorCode, isRetryableMessage);
  pollJobResult() now continues polling for retryable codes/messages
  and raises OperationalError/ProgrammingError for fatal ones.
- Add DB-API-style exception hierarchy (ClickZettaError with Interface/
  Database/Operational/Programming/Data/Integrity/NotSupported). Keep
  ClickZettaApiError for back-compat by re-rooting it on OperationalError.
- Extend coerceValue with DATE / TIMESTAMP_LTZ / TIMESTAMP_NTZ (ISO),
  BINARY/VARBINARY (hex → Uint8Array), JSON auto-parse, CHAR/VARCHAR
  pass-through, INTERVAL/VECTOR/BITMAP/VOID pass-through.
- Tests: 18 cases across errors.test.ts / coerce.test.ts / token.test.ts
  (bun test, all passing).

Subject: [PATCH 025/521] fix(clickzetta-sdk): align Task A with Python
 connector line-by-line review
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Findings from the line-by-line review of commit 2e1a289f5 against
clickzetta-connector-python:

- login.ts: replace the single-shot login with the Python retry loop
  (client.py:296-392). 5 retries, backoff = min(2^n * 100ms, 2000ms),
  10s per-attempt timeout, and instance-config error detection for
  both the Chinese ("没有这样的元素") and English ("No such element")
  gateway messages. The latter now raises InterfaceError so callers
  see a precise diagnosis instead of a generic 4xx.

- poll.ts: cap NoPermission ("User … is not found") retries at 5 to
  match Python's `tried < 5` guard (client.py:1232-1234). Previously
  TS would retry forever on a bad grant.

- poll.ts: early-return when resultSet.data/location is populated
  even if state is still QUEUEING/SETUP/RUNNING/RESUMING_CLUSTER
  (client.py:1222-1230). The server occasionally emits the payload
  before flipping state to SUCCEED; we now accept it instead of
  continuing to poll.

Accepted divergences (documented, not changed):
- _get_job backoff. Python uses `min(2^n, 10)s` strictly for /lh/getJob
  network errors; TS routes those through client.ts retryDelayMs which
  is already exponential-with-jitter. Keeping the split.
- 28-delimiter TEXT decoder. TS uses JSON.parse for MAP/ARRAY/STRUCT
  which works because the server emits JSON-encoded containers in TEXT
  mode. Full delimiter table would be dead code.

 SQLWriteDetector
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New package @clickzetta/mcp-server. This commit lands only the
pieces that are line-by-line aligned with the Python reference and
unblock the remaining MCP blocks without locking other work.

Python → TS mapping:
- cz_mcp/core/write_detector.py:1-263 → src/sql-write-detector.ts
  - DML_WRITE_KEYWORDS / DDL_KEYWORDS / DCL_KEYWORDS sets (py:12-16)
  - analyze_query           → SQLWriteDetector.analyzeQuery (py:21-62)
  - _has_cte + _analyze_cte → analyzeCte (py:64-107)
  - _find_write_operations  → findWriteOperations (py:109-153)
  - _is_function_call       → isFunctionCall (py:155-168)
  - _is_read_only_show_command → isReadOnlyShowCommand (py:170-178)
  - _detect_create_or_replace  → detectCreateOrReplace (py:180-192)
  - _determine_operation_type  → determineOperationType (py:194-263)
- cz_mcp/core/logger.py (loguru wrapper) → src/logger.ts (pino)

New dependencies (reason):
- @modelcontextprotocol/sdk@1.29.0 — MCP protocol implementation
- @hono/node-server@1.17.1        — HTTP transport runtime
- pino@9.5.0                      — structured logger (loguru analogue)
- hono (catalog), zod (catalog)   — already present

Accepted divergences:
- No sqlparse dependency. TS uses a hand-rolled tokenizer that strips
  comments/literals before keyword matching. Behavioural contract is
  preserved for all Lakehouse keywords; the Python code already falls
  back to string matching for edge cases (write_detector.py:142-151).
- loguru → pino (structured JSON logs; Python side writes rotated
  plain-text files that are not part of the protocol surface).

Tests: 10 cases in test/sql-write-detector.test.ts (bun test, passing).
Typecheck clean via tsconfig.srconly.json (excludes bun:test types).

Remaining Block 1 work (server.ts, tool-registry.ts, stdio.ts, http.ts,
bin/run-*.ts) lands in subsequent commits.

Subject: [PATCH 027/521] feat(clickzetta-sdk): add SqlSession with SET/USE
 handling and full hints/configs alignment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Aligns the TS submit flow with clickzetta-connector-python line-by-line so
the submit body contains the same configStatements, configs, hints,
polling timeout, priority, and jobTimeoutMs as the Python connector.

Python -> TS mapping:
- client.py:69  DEFAULT_MAXIMUM_TIMEOUT=60     -> session.ts DEFAULT_MAXIMUM_TIMEOUT
- client.py:125 max_retries=120                 -> session.ts DEFAULT_MAX_RETRIES
- client.py:201 config_statements=[]            -> SqlSession.configStatements
- client.py:494-502 set_config(sql)             -> SqlSession.setConfigFromSql
- client.py:504-505 get_configs                 -> SqlSession.getConfigs
- client.py:507-508 get_config                  -> SqlSession.getConfig
- client.py:510-519 pre_process_sql             -> SqlSession.preProcessSql (keeps \n; suffix)
- client.py:535-560 process_use_cmd             -> SqlSession.processUseCmd (USE VCLUSTER/WORKSPACE/SCHEMA/<schema> + SET)
- client.py:562-567 get_real_schema             -> session.ts getRealSchema
- utils.py:212-227 strip_leading_comment        -> session.ts stripLeadingComment
- enums.py:124-163 CZConnectContext             -> SqlSession state (workspace/schema/vcluster/configs/maxRowSize)
- enums.py:162-163 CZConnectContext.set_config  -> SqlSession.setConfig
- enums.py:166-178 ClientContextInfo            -> submit.ts clientContext{configStatements, contextJson}
- client.py:598-602 submit defaults             -> SqlSession.prepareSubmit initial locals (polling=30, priority=0, timeout=0)
- client.py:603-604 hints = configs; update(self.hints) -> prepareSubmit merges session hints into this.configs (by-reference like Python)
- client.py:605-610 params['hints'] + %(key)s   -> prepareSubmit params.hints merge + pyformat split/join replace
- client.py:611-635 hints dispatch              -> prepareSubmit key switch (polling/priority/timeout/maxRetry/timezone/default.ns/maxRowSize)
- client.py:641-644 polling_timeout clamp       -> prepareSubmit async=>0; >DEFAULT_MAXIMUM_TIMEOUT=>60
- client.py:645 SQLJobConfig(hint=configs)      -> submit.ts sqlJob.sqlConfig.hint (fed by prepared.sqlConfigHint)
- client.py:647-657 schema / override_workspace -> prepareSubmit submitWorkspace/submitSchema + sdk.job.default.ns split
- client.py:658-660 job_timeout_ms overflow     -> prepareSubmit Number.MAX_SAFE_INTEGER clamp
- client.py:661-676 JobDesc assembly            -> submit.ts jobDesc + contextJson pass-through; enums.py:348-351 query_tag/jobTimeoutMs guards preserved

Accepted divergences:
- processUseCmd does not call check_schema() (Python client.py:521-533, 554). The TS session is a pure client-side layer; it only normalises the schema identifier via getRealSchema and defers existence validation to the server. Noted in-source.
- setConfigFromSql throws InterfaceError (our DB-API error base) instead of a bare Exception as Python does.
- The sdk.query.max.retries dispatch updates the resolved maxRetry in PreparedSubmit but does not yet drive the execute_with_retrying loop; the TS submit currently relies on doRequest's retry ladder. This is surfaced in PreparedSubmit.maxRetry so a future layer can wire it up.
- pyformat substitution stringifies via String(value) for all non-hints keys. Python uses str(), matching behaviour for numbers/strings; null/undefined become literal "null"/"undefined" in TS. Callers should provide sanitised values.
- contextJson is built from the current session state (enums.py:143-154) but user is taken from config.username rather than the server-resolved principal; Python tracks the latter via the login flow.

submit.ts changes:
- SubmitJobParams gains configStatements/priority/pollingTimeout/contextJson fields (all optional) while keeping the original workspace/schema/vcluster/instanceName/instanceId/jobId/sql/hints/asynchronous/jobTimeoutMs shape so cz-cli exec.ts continues to compile unchanged.
- hybridPollingTimeout defaults honour the new pollingTimeout; query_tag and jobTimeoutMs are only emitted when present (enums.py:348-351 parity).

Tests: test/session.test.ts — 38 cases (stripLeadingComment, normalizeWhitespace, getRealSchema, SET/USE branches incl. leading comment + embedded-space rejection, multi-statement preProcessSql, hints three-layer merge, pyformat substitution, polling clamp, priority aliases, sdk.query.timeout.ms -> sdk.job.timeout routing, cz.sql.timezone mirror, sdk.job.default.ns override, maxRowSize mirror, unknown hint fallthrough, async polling=0, configStatements propagation). Full SDK suite: 56 pass / 0 fail. Typecheck clean for clickzetta-sdk src and cz-cli.

Subject: [PATCH 028/521] feat(mcp-server): add ToolRegistry and LakehouseDB
 skeleton (Block 1b)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- tool_registry.py:47-54   Tool model          → ToolDefinition interface
- tool_registry.py:57-164  ToolDefinitionCache → ToolDefinitionCache class
- tool_registry.py:167-206 register_tools      → ToolRegistry.registerTools
- tool_registry.py:208-236 _validate_tool      → ToolRegistry._validateTool
- tool_registry.py:250-284 get_allowed_tools   → ToolRegistry.getAllowedTools
- tool_registry.py:330-384 _process_tool_for_list → ToolRegistry._processToolForList
- tool_registry.py:386+    get_mcp_tool_list   → ToolRegistry.getMcpToolList
- tool_registry.py:15-44   SYSTEM_PROMPT/consts → constants
- server_core.py:28-80     EnhancedLakehouseDB → LakehouseDB class
- server_core.py:35        AUTH_EXPIRATION_TIME = 1800
- server_core.py:203-271   executeQuery stub   → LakehouseDB.executeQuery (NotSupportedError)

Accepted divergences:
- No threading.RLock (TS single-threaded); stats tracking preserved.
- LakehouseDB.executeQuery is a stub; real impl in Block 2.
- ConnectionException/QueryExecutionException use field assignment
  instead of constructor parameter properties to satisfy tsgo strict mode.

Tests: 10 cases in test/sql-write-detector.test.ts (bun test, passing).
Typecheck clean via tsconfig.srconly.json.

Subject: [PATCH 029/521] test(mcp-server): add tool-registry test suite (Block
 1b)

22 test cases covering ToolDefinitionCache and ToolRegistry:
- cache miss/hit tracking, copy-on-return, preload, clearCache stats reset
- registerTools, getToolHandler, getToolSchema (null for unknown)
- _validateTool throws on missing name/description/inputSchema/type
- getToolsByTag appends TOP_LEVEL_DESCRIPTION
- getAllowedTools filters by name and tag
- getMcpToolList injects region/workspace/vcluster/schema params
- reset clears all state

bun test: 32 pass (22 new + 10 existing), 0 fail.

Subject: [PATCH 030/521] feat(mcp-server): add STDIO transport and config
 loader (Block 1c)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- run_stdio_server.py:20-78   argparse         → node:util parseArgs in run-stdio.ts
- run_stdio_server.py:80-135  config loading   → StudioConfigManager.loadFromFile
- run_stdio_server.py:135-145 log init         → pino file transport (stderr default, file when --enable-local-log)
- run_stdio_server.py:145-178 server startup   → runStdio() + MCP SDK Server
- transport/mcp_server.py:961-983 stdio section → transport/stdio.ts

Accepted divergences:
- ClickzettaMCPServer not yet ported (Block 2); run-stdio.ts uses bare MCP SDK Server
- StudioConfig in profile.ts coexists with server.ts placeholder; index.ts exports StudioConfigManager explicitly to avoid ambiguity
- loguru → pino (stderr fd by default, pino.transport file sink when --enable-local-log)
- asyncio.run(main()) → top-level await (Bun native support)

Tests: 33 cases (bun test, passing). STDIO handshake smoke-tested manually.

Subject: [PATCH 031/521] feat(clickzetta-sdk): implement Volume GET/PUT with
 retry and pagination (Task C)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- client.py:1340-1344 _process_hint_job volume branch → isVolumeSql
- client.py:863-894   process_volume_sql              → processVolumeSql
- client.py:897-924   _is_retryable_volume_transfer_exception → isRetryableVolumeError
- client.py:926-964   _execute_volume_transfer_with_retry     → executeVolumeTransferWithRetry
- client.py:966-1040  gen_volume_result               → genVolumeResult
- client.py:1042-1053 get_volume_files                → getVolumeFiles
- client.py:1420-1442 _gen_new_put_sql                → genNewPutSql
- _volume.py:22-27    resolve_local_path              → resolveLocalPath
- utils.py:187-209    normalize_file_path             → normalizeFilePath

Accepted divergences:
- normalizeFilePath uses process.env HOME/USERPROFILE instead of os.homedir()
  (avoids require() at module load; functionally equivalent on Node.js)
- getVolumeFiles uses synchronous require("node:path") for basename/resolve
  (function is sync; dynamic import would require making it async)
- executeVolumeTransferWithRetry accepts optional _sleepFn for test injection
  (Python uses time.sleep directly; TS needs testability without real delays)
- resolveLocalPath implements single-level glob only (Python uses Path.glob
  which supports recursive **; single-level covers the PUT use case)
- Added @types/node devDependency and tsconfig.srconly.json (mirrors mcp-server
  pattern; required for Node.js fs/path/os type declarations)

Tests: 42 cases in test/volume.test.ts (bun test, all 98 passing including original 56).

Subject: [PATCH 032/521] feat(mcp-server): add HTTP transport with Bearer auth
 (Block 1d)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- run_http_server.py:83-113 argparse          → node:util parseArgs in run-http.ts
- run_http_server.py:116-126 parse_port()     → parsePort() with random-port support
- run_http_server.py:20-80 setup_logging()    → pino with optional file transport
- run_http_server.py:137-155 startup banner   → logger.info calls in run-http.ts
- run_http_server.py:163-165 server startup   → Server + runHttp() in run-http.ts
- transport/mcp_server.py:939-959 HTTP branch → transport/http.ts runHttp()
- transport/mcp_server.py:945-953 FastMCP HTTP → WebStandardStreamableHTTPServerTransport
- core/mcp_middleware.py:14-35 bearer verify  → auth/bearer.ts bearerAuthMiddleware()

Accepted divergences:
- FastAPI/uvicorn → Hono + Node.js createServer (web-standard transport)
- Python RotatingFileHandler → pino file transport (rotation via logrotate in prod)
- Python ClickzettaMCPServer → bare MCP SDK Server (Block 2 wires real tools)
- mcp_middleware.py uses HornhubClient JWT verify → static token comparison

Tests: 37 cases (bun test, passing, 4 new HTTP cases). /health smoke-tested.

Subject: [PATCH 033/521] fix(mcp-server): align write-detector with Python
 line-by-line review

Two missing branches found by post-Block-1 review:

- write_detector.py:166 token.endswith('(') check in _is_function_call:
  Python checks if the token itself ends with '(' (e.g. TRUNCATE( as a
  single token). TS only checked the *next* token. Added the self-check.

- write_detector.py:142-151 string-based startswith detection:
  Python iterates all tokens and adds a keyword when token_str starts
  with 'KEYWORD '. TS tokenizer already splits on whitespace so the
  primary loop catches these, but the explicit includes() pass is added
  for edge cases where the tokenizer might miss a compound token.

Tests: 52 pass (bun test).

Subject: [PATCH 034/521] fix(mcp-server): add _fetchManagedWorkspaces from
 Block 2 review

server_core.py:184-201 _fetch_managed_workspaces was missing from the
TS executeQuery re-init path (server_core.py:157 calls it after connect).

Added LakehouseDB._fetchManagedWorkspaces():
- Runs SHOW CATALOGS WHERE category='MANAGED'
- Populates this.managedWorkspace
- Failure is non-fatal (falls back to empty list, matching Python behaviour)

Called from executeQuery after session re-init, matching server_core.py:157.

Tests: 52 pass.

Subject: [PATCH 035/521] fix(clickzetta-sdk): align request id, NoPermission,
 and resultSet checks

Four findings from Task A patch review and Task B SqlSession review:

1. Missing requestId header (client.py:292-293, 305, 321)
   Python's generate_header() injects a 'requestId: pysdk-v{ver}-{uuid}'
   header on every request; the gateway relies on it for log correlation.
   Added generateRequestId() in client.ts:buildHeaders and auth/login.ts.

2. NoPermission retry used includes() instead of endsWith() (poll.ts:470)
   client.py:1232 checks error_msg.endswith(' is not found'). Changed TS
   to .endsWith() so unrelated errors containing the phrase mid-message
   don't get silently retried 5 times.

3. resultSet.location early-return was too strict (poll.ts:490)
   client.py:1228 checks only 'location' in result_dict['resultSet']
   (the object's mere presence is enough). TS was gating on
   presignedUrls.length > 0, which could miss location objects carrying
   other fields. Switched to a null-only check.

Tests: 98 pass.

Subject: [PATCH 036/521] feat(mcp-server): port region_config.py + wire alias
 resolution into STDIO CLI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

region_config.py was stubbed out in Block 1b (getRegionDescription returned
empty string), and run_stdio_server.py:101-106 apply_cli_config_overrides
wasn't ported at all — meaning:
  - Tool descriptions shipped without the 12-region alias table the LLM
    needs to route region-aware requests correctly.
  - CLI --x-lakehouse-region was passed through as-is; Chinese aliases
    like '阿里云' / '快手新加坡' would never resolve.
  - CLI --x-lakehouse-service without --x-lakehouse-region would not
    auto-infer a region, forcing users to specify both.

Python → TS mapping:
- region_config.py:12-38   Region enum              → src/config/region.ts Region
- region_config.py:41-94   REGION_ALIASES           → REGION_ALIASES (byte-identical)
- region_config.py:97-103  get_region_by_alias      → getRegionByAlias
- region_config.py:106-116 _normalize_service_host  → normalizeServiceHost
- region_config.py:119-137 get_region_by_service_url → getRegionByServiceUrl
- region_config.py:140-147 get_region_code_by_cregionid → getRegionCodeByCregionId
- region_config.py:150-162 get_available_regions    → getAvailableRegions
- region_config.py:165-209 get_region_description   → getRegionDescription
- run_stdio_server.py:101-106 region resolution     → bin/run-stdio.ts

Accepted divergences:
- getRegionByServiceUrl takes an in-memory url table instead of reading
  cz_mcp/config/config.ini directly. Callers that want the full Python
  behaviour pass the parsed [URL] section; the STDIO CLI currently calls
  with null and relies on the alias table.
- Duplicate keys where a Chinese alias and Region.XXX value collide (e.g.
  'kuaishou' === Region.KUAISHOU) are listed once only — TS object literals
  reject duplicates, Python overwrote them to the same value anyway.

Tests: 64 pass (12 new in test/region.test.ts).

Subject: [PATCH 037/521] fix(clickzetta-sdk): align job id format and
 execute() guards with cursor.py
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three alignment gaps found while cross-checking cursor.py against session.ts:

1. newJobId used an arbitrary 'tssdk-{hex}' scheme; Python generates
   'YYYYMMDDHHMMSSffffff' + 5-digit random (client.py:1347-1352). The
   gateway routes / correlates by this format — mismatched IDs showed up
   as unknown in server-side logs. Ported formatJobIdCore() verbatim.

2. execute() did not validate the SQL argument. Python raises
   ValueError('sql is empty') when operation is None or '' after strip
   (cursor.py:172-177). Added matching guards that throw ProgrammingError
   (DB-API equivalent).

3. execute() did not auto-append ';' to the final statement. Python does
   this at cursor.py:180 so single-statement queries parse correctly on
   the server side. TS now does the same before prepareSubmit.

Tests: 103 pass (+5 new).

Subject: [PATCH 038/521] feat(clickzetta-sdk): add Arrow IPC decoder + fix
 ARROW/TEXT format routing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Python connector defaults to ARROW format (enums.py:136) but the TS
SDK was silently sending TEXT and only decoding TEXT. This commit:

1. Adds src/sql/arrow.ts — full Arrow IPC decoder (query_result.py:57-80):
   - base64 → Uint8Array → apache-arrow tableFromIPC → row-major records
   - Handles TIMESTAMP_LTZ/NTZ (→ ISO 8601), DATE, BINARY, INT64/BIGINT
     (BigInt → Number when safe, else string), DECIMAL (string), MAP/LIST/
     STRUCT (pass-through JS objects from apache-arrow)
   - fetchArrowFromUrls for presigned URL path
   - Mirrors query_result.py:68-73 column dedup by rename

2. Restores DEFAULT_CONFIGS.adhoc.default.format = "ARROW" in session.ts
   and submit.ts (was incorrectly changed to TEXT in a prior commit).

3. Wires format detection into poll.ts parseResultSet and parseJobResponse:
   - Reads metadata.format (default "ARROW" per query_result.py:297)
   - Routes embedded data to decodeArrowPayload or textToRows accordingly
   - Routes presigned URL fetch to fetchArrowFromUrls or fetchTextFromUrls

4. Adds apache-arrow@21.1.0 as a runtime dependency.

Tests: 106 pass (3 new in test/arrow.test.ts).

Subject: [PATCH 041/521] fix(clickzetta-sdk): port as_timezone to coerceValue
 for TIMESTAMP_LTZ

utils.py:278-300 as_timezone converts TIMESTAMP_LTZ values to the
session's configured timezone. The TEXT path in coerceValue was only
normalising the space separator; it was not applying any timezone
conversion, so all LTZ timestamps were returned in whatever offset the
server embedded in the string.

Changes:
- coerceValue gains an optional timezone parameter (utils.py:278-300)
- TIMESTAMP_LTZ/TIMESTAMP branch calls applyTimezone(iso, timezone) when
  a timezone is provided; TIMESTAMP_NTZ is unchanged (wall-clock, no tz)
- applyTimezone uses Intl.DateTimeFormat('sv-SE') to produce a
  YYYY-MM-DDTHH:MM:SS.mmm string in the target timezone
- PollJobResultParams gains timezone?: string
- parseResultSet / parseJobResponse / pollJobResult thread the timezone
  through to every coerceValue call
- SqlSession.execute passes this.timezoneHint into pollJobResult

Tests: 106 pass.

client.py:1111-1129 defines get_job_profile/result/progress/summary/plan

Subject: [PATCH 043/521] fix(clickzetta-sdk): cancel job on timeout before
 throwing (client.py:1101-1108)

Python's _check_job_timeout_with_cancel calls cancel_job() before raising
the timeout exception. TS was only throwing without cancelling, leaving
the job running on the server. Now does a best-effort cancel (errors
ignored) then throws OperationalError.

Subject: [PATCH 044/521] feat(clickzetta-sdk): port Converter.escape/quote to
 sql/literal.ts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

converter.py:218-268 defines escape() and quote() for embedding Python
values into SQL strings. These were listed as [必须补] in the initial
analysis but never implemented.

Python → TS mapping:
- converter.py:218-227 Converter.escape → escape()
- converter.py:229-268 Converter.quote  → quote()
  - null/undefined → NULL
  - boolean → true/false
  - number/bigint → repr
  - Uint8Array → X'<hex>'
  - string → '<escaped>' with INTERVAL/TIMESTAMP/DATE/JSON pass-through
  - Date → TIMESTAMP '<iso>'
  - Array → ARRAY(...)
  - Map / plain object → MAP(...)

Tests: 131 pass (+25 new in test/literal.test.ts).

Subject: [PATCH 046/521] feat(mcp-server): implement Block 4 tools (partial:
 11 of ~15 files)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements the following tool groups from Block 4:
- tools/cdc.ts         — cdc_realtime_tools.py
- tools/datasource.ts  — datasource_tools.py
- tools/datetime.ts    — datetime_tools.py
- tools/execute.ts     — execute_tools.py
- tools/folder.ts      — folder_tools.py
- tools/knowledge.ts   — knowledge_index_tools.py
- tools/optimize.ts    — optimize_tools.py
- tools/schedule-task.ts — schedule_task_tools.py
- tools/skill.ts       — skill_tools.py
- tools/vc.ts          — vc_tools.py
- tools/workspace.ts   — workspace_tools.py

Remaining (backfill/semantic-view/integration/flow-task/schedule-instance)
will land in a follow-up commit once the remaining subagents complete.

Tests: 64 pass (bun test).

+
+            Create and optionally trigger DQC (Data Quality Check) rule execution.
+
+            **Core Features:**
+
+            1. **Rule Creation**
+               - Create manual (REST), scheduled (PLAN), or task-based (SCHEDULE_TASK) DQC rules
+               - Support built-in metrics (table_count, avg, count, etc.) and custom SQL
+               - Auto-generate checker_info from operator and expected_value
+
+            2. **Flexible Trigger Options**
+               - REST: Manual trigger rules
+               - PLAN: Scheduled rules with cron expressions
+               - SCHEDULE_TASK: Task-based rules with blocking levels
+
+            3. **Auto-Trigger Capability**
+               - Set auto_trigger=true to execute rule immediately after creation
+               - Only works for REST type rules
+               - Returns both rule_id and task_id
+
+            **Built-in Metrics:**
+            - table_count: Total rows in table (no column needed)
+            - count: Non-null count in column
+            - null_count: Null count in column
+            - count_distinct: Unique values in column
+            - count_repetition: Duplicate values in column
+            - avg, max, min, sum: Numeric aggregations (require column)
+
+            **Operators:**
+            - GREATER_THAN, LESS_THAN, EQUAL, NOT_EQUAL, GREATER_EQUAL, LESS_EQUAL
+
+            **Example Usage:**
+            \`\`\`

Subject: [PATCH 047/521] feat(clickzetta-sdk): port parse_url.py to
 config/parseUrl.ts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

parse_url.py was listed as [必须补] in the initial analysis but never
implemented. Adds full clickzetta:// URL parsing and generation.

Python → TS mapping:
- parse_url.py:25-98   parse_url      → parseConnectionUrl
- parse_url.py:101-113 generate_url   → generateConnectionUrl
- parse_url.py:14-21   parse_boolean  → parseBoolean
- (new) connectionConfigFromUrl — convenience wrapper returning ConnectionConfig

Handles all URL features:
- instance.host extraction (py:30-32)
- /api/ path prefix (py:38-44)
- protocol param (py:46-56)
- virtualcluster/virtualCluster/vcluster aliases (py:63-71)
- magic_token, token_expire_time_ms, schema (py:73-76)
- extra query params preserved (py:97)

Tests: 139 pass (+8 new in test/parseUrl.test.ts).

 JobNotExistsError
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- mcp-server: tools/backfill.ts — backfill_task_tools.py port
  (get_backfill_task_detail_tools, list_backfill_tasks_tools,
   list_backfill_instances_tools)

- clickzetta-sdk: types/errors.ts — add JobNotExistsError extending
  ProgrammingError (exception.py:29-32 ClickzettaJobNotExistsException).
  toClickZettaError now returns JobNotExistsError for CZLH-60005 so
  callers can catch it specifically.

Tests: 139 pass (sdk), 64 pass (mcp-server).

Subject: [PATCH 049/521] fix(clickzetta-sdk): add close() and closed-state
 guard to SqlSession

connection.py:61-62 sets _closed=True on close(); _dbapi_helpers.py:6-15
raise_on_closed decorator throws ProgrammingError when a closed connection
is used. SqlSession had neither.

Added:
- SqlSession._closed private field
- SqlSession.close() method (connection.py:61-62)
- SqlSession.isClosed getter
- execute() checks _closed before proceeding (_dbapi_helpers.py:6-15)

Subject: [PATCH 057/521] feat(mcp-server): implement integration tools (Block
 4e)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- integration_templates.py:25-929  → IntegrationTemplateLibrary (inlined)
- integration_config_tools.py:20-113  → generateConfig()
- integration_config_tools.py:115-187 → getTableColumns()
- integration_config_tools.py:189-257 → buildJob()
- integration_config_tools.py:259-295 → buildParams()
- integration_config_tools.py:297-323 → mapColumns()
- integration_config_tools.py:326-405 → handleRecommendIntegrationConfig()
- integration_config_tools.py:408-569 → registerIntegrationTools()

Subject: [PATCH 058/521] feat(mcp-server): add MCPBaseException hierarchy +
 integration/semantic-view tools
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

exceptions.py:11-165 → server.ts:
- MCPBaseException (base with errorCode/details/timestamp/toDict)
- ToolExecutionException, ValidationException, PermissionException
- TransportException, mapException()
- ConnectionException/QueryExecutionException now extend MCPBaseException

Block 4e tools:
- integration_config_tools.py → tools/integration.ts
- semantic_view_tools.py → tools/semantic-view.ts

Tests: 64 pass.

Subject: [PATCH 059/521] feat(mcp-server): implement execute/schedule-instance
 tools (Block 4b)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- execute_tools.py:28-493 → tools/execute.ts (already committed)
- schedule_instance_tools.py:426-581 → registerScheduleInstanceTools list_task_run
- schedule_instance_tools.py:659-722 → registerScheduleInstanceTools get_task_run_dependencies
- schedule_instance_tools.py:802-866 → registerScheduleInstanceTools get_execution_log
- schedule_instance_tools.py:948-1006 → registerScheduleInstanceTools list_executions
- schedule_instance_tools.py:1100-1248 → registerScheduleInstanceTools get_task_run_stats

Adds missing registerScheduleInstanceTools() export with all 5 tool
definitions aligned to Python reference. All 64 tests pass.

Subject: [PATCH 060/521] feat(mcp-server): port HornhubClient + fix
 MCPBaseException override
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hornhub_client.py:57-105 → auth/hornhub-client.ts:
- HornhubClient.checkAccessToken (SHA-256 token hash → Hornhub API)
- HornhubClient.getInstance
- HornhubClient.generateTokenHash
- HornhubError, BaseUser, ServiceInstance types

Also fixes MCPBaseException.cause needing 'override' modifier (tsgo strict).

Subject: [PATCH 063/521] feat(mcp-server): complete Block 4 - all 20 tool
 files + tools/index.ts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All tool groups from cz_mcp/tools/__init__.py:get_all_tools() are now
implemented in TypeScript:

tools/index.ts — registerAllTools() wires all 19 tool groups
tools/flow-task.ts — flow_task_tools.py (handler stubs, register placeholder)
tools/semantic-view.ts — semantic_view_tools.py (full implementation)

Note: flow-task.ts registerFlowTaskTools() is a placeholder pending
full tool definition porting (flow_task_tools.py:491-859 has 369 lines
of tool schemas). Handler functions are complete.

Tests: 64 pass.

Subject: [PATCH 065/521] feat(mcp-server): port argument-normalizer +
 request/config utils
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- argument_normalizer.py:20-35   → transport/argument-normalizer.ts (ArgumentNormalizationError)
- argument_normalizer.py:37-529  → transport/argument-normalizer.ts (ArgumentNormalizer class)
- argument_normalizer.py:531-553 → transport/argument-normalizer.ts (create_normalizer_for_tool)
- request_utils.py:9-40          → utils/request.ts (Request class)
- config_utils.py:1-87           → utils/config.ts (readIni/readUrl/readApi/etc.)

Divergences:
- Python inspect.signature → TS uses inputSchema.type for type conversion
- Python configparser → TS built-in INI parser (no new deps)
- Python jsonpath_ng → TS dot-notation path resolver (no new deps)
- Python requests+urllib3 → TS built-in fetch API

+ *
+ * Divergence from Python:
+ *   - Python uses inspect.signature to extract handler parameter types at runtime.
+ *     TS cannot reflect function signatures at runtime, so type conversion is driven
+ *     entirely by input_schema's `type` field (same data, different source).
+ *   - handler_params is always treated as non-empty (schema-driven), so the
+ *     `if not self.handler_params: return arguments` guard in _convert_types is
+ *     replaced by checking whether properties exist in the schema.

+/**
+ * config utils — port of cz-mcp-server/cz_mcp/utils/config_utils.py
+ *
+ * Python → TS mapping:
+ *   config_utils.py:8-9    module-level conf + path setup → configDir constant
+ *   config_utils.py:11-18  read_ini()                     → readIni()
+ *   config_utils.py:21-31  read_url()                     → readUrl()
+ *   config_utils.py:33-43  read_web_url()                 → readWebUrl()
+ *   config_utils.py:46-52  read_api()                     → readApi()
+ *   config_utils.py:55-62  read_env_configuration()       → readEnvConfiguration()
+ *   config_utils.py:65-71  read_data_source_config()      → readDataSourceConfig()
+ *   config_utils.py:74-80  read_sections_ini()            → readSectionsIni()
+ *   config_utils.py:82-87  read_config_ini()              → readConfigIni()
+ *
+ * Divergences from Python:
+ *   - Python uses configparser (INI file parser) + a module-level shared ConfigParser instance.
+ *     TS uses a simple synchronous INI parser (no new npm deps) with a module-level cache.
+ *   - Python's context dict (context_utils.py) is replaced by a module-level `context` map.
+ *   - Function names are camelCase per TS convention.
+ *   - Python's loguru logger is replaced by console.error for error reporting.

Subject: [PATCH 066/521] feat(mcp-server): port job_performance_handler.py
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- job_performance_handler.py:14-33  FINDING_REFERENCE_MAP → FINDING_REFERENCE_MAP
- job_performance_handler.py:36-81  _load_reference_files → loadReferenceFiles
- job_performance_handler.py:83-95  _estimate_expert_mode_tokens → estimateExpertModeTokens
- job_performance_handler.py:97-174 analyze_job_performance → analyzeJobPerformance

New file: src/handlers/job-performance.ts
New file: src/handlers/index.ts (re-exports job-performance)
Updated: src/tools/optimize.ts — handleJobPerformanceAnalysis now delegates
  to analyzeJobPerformance() instead of inlining the result construction

Subject: [PATCH 067/521] fix(mcp-server): remove broken analyzeJobPerformance
 call in optimize.ts

The tool description states it "Fetches raw job plan and profile data ...
does NOT interpret results", so return raw data directly instead of
calling a non-existent analyzeJobPerformance handler.

+
+# Job Performance Analyzer
+
+## 概述
+
+自动诊断 Clickzetta Job 性能问题的工具，分析执行计划和运行概况，识别瓶颈并给出参数优化建议。
+
+## 已实现规则
+
+**Stage/Operator 级别优化** (9条规则):
+- `refresh_type_detection` - 增量/全量刷新判断
+- `single_dop_aggregate` - 单并行度聚合优化（三阶段聚合、Bloom Filter 收集检测）
+- `hash_join_optimization` - Broadcast Hash Join 优化
+- `tablesink_dop` - TableSink DOP 自动调整检测
+- `max_dop_check` - 最大 DOP 限制提示
+- `spilling_analysis` - 内存溢出分析
+- `skew_detection` - 数据倾斜检测
+- `resource_efficiency_analysis` - 资源效率分析（对比实际耗时与理论资源充足预期耗时）
+- `active_problem_finding` - 主动瓶颈分析
+
+**状态表优化** (6条规则):
+- `non_incremental_diagnosis` - 全量刷新原因诊断
+- `row_number_check` - ROW_NUMBER=1 pattern 检查
+- `append_only_scan` - Append-Only 表识别
+- `state_table_enable` - 状态表启用建议
+- `aggregate_reuse` - 聚合结果复用检查
+- `heavy_calc_state` - 高耗时 Calc 状态优化
+
+### Usage
+
+MCP Tool Call 示例
+
+#### 基本分析（仅 Stage/Operator 级别优化，默认）
+```json
+{
+  "name": "fetch_job_performance_data",
+  "arguments": {
+    "workspace_name": "your_workspace",
+    "job_id": "2026012808001805432z9g3fx1sok"
+  }
+}
+```
+
+如果结果是“未发现需要调整的参数”，则表示当前作业性能良好，无需进一步优化。
+
+#### quick 模式（默认，纯规则引擎，零 AI 消耗）
+```json
+{
+  "name": "fetch_job_performance_data",
+  "arguments": {
+    "workspace_name": "your_workspace",
+    "job_id": "2026012808001805432z9g3fx1sok"
+  }
+}
+```
+- 不传 `analysis_mode` 或传 `"quick"` 均为此模式
+- 纯规则引擎分析，不消耗 AI token，适合日常巡检和批量扫描
+- 输出内容：概况 + 参数建议 + 关键洞察（仅 `important` 级别，如资源效率分析）
+- 不输出 findings 详情和 detail 级别 insights（需要可切换 standard 模式）
+- 如果结果是"未发现需要调整的参数"且无关键洞察，表示当前作业性能良好
+
+#### Standard 模式（详细分析，规则引擎 + AI 研判数据）
+```json
+{
+  "name": "fetch_job_performance_data",
+  "arguments": {
+    "workspace_name": "your_workspace",
+    "job_id": "2026012808001805432z9g3fx1sok",
+    "analysis_mode": "detailed"
+  }
+}
+```
+
+#### Expert 模式（深度分析，需用户确认）
+```json
+{
+  "name": "fetch_job_performance_data",
+  "arguments": {
+    "workspace_name": "your_workspace",
+    "job_id": "2026012808001805432z9g3fx1sok",
+    "analysis_mode": "expert"
+  }
+}
+```
+
+**参数说明**：
+- `workspace_name` (必需): 工作空间名称
+- `job_id` (必需): 作业ID
+- `user_id` (可选): 用户ID，默认使用当前用户
+- `analysis_mode` (可选): 分析模式，默认 `quick`
+  - `quick` — 纯规则引擎，零 AI 消耗，适合日常巡检
+  - `detailed` — 规则引擎 + AI 研判数据（含 analysis_scope、stage_summary、全部 findings/insights），适合排查问题
+  - `expert` — 深度分析，按需加载 reference 文档，消耗较多 token。返回 `requires_confirmation=true` 和 `token_estimate`
+
+**分析模式说明**：
+- `quick`（默认）：与现有行为完全一致，findings 过滤掉 INFO/LOW 级别，insights 仅输出 important 级别
+- `detailed`：输出全部 findings/insights + analysis_scope（规则引擎中间计算数据），附带 AI 研判 prompt
+- `expert`：在 detailed 基础上，根据 findings 类型自动加载对应的 reference 文档（如 stage-operator-optimization.md、state-table-optimization.md），供 AI 做深度根因分析和优化方案设计
+
+**工具功能**：
+1. 自动获取job plan和job profile数据
+2. 调用性能分析器进行分析
+3. 返回优化建议和诊断结果
+
+
+### 用户意图映射
+
+当 AI 调用此工具时，根据用户的自然语言严格按关键词选择分析模式（不要自行升级）：
+
+1. **quick 模式**（默认，纯规则引擎）— 用户没有明确要求"详细"或"专家"时一律用 quick：
+   - "帮我分析 job xxx"
+   - "快速看看 job xxx 有没有问题"
+   - "给出任务 xxx 的优化建议"
+   - "再分析下这个 job"
+
+2. **detailed 模式**（详细分析，仔细分析，规则引擎 + AI 研判）— 仅当用户说"详细"或"仔细"时：
+   - "帮我详细分析 job xxx"
+   - "再详细分析下这个 job"
+   - "仔细看看 job xxx 的性能问题"
+
+3. **expert 模式**（专家分析，需用户确认 token 消耗）— 仅当用户原话包含"专家模式"、"深度分析"或"全面分析"时：
+   - "用专家模式分析 job xxx"
+   - "深度分析 job xxx"
+   - "帮我全面分析 job xxx"
+   - ⚠️ 注意："详细分析"是 detailed，不是 expert
+
+3. **不适用场景（禁止触发本 skill）**：
+   - "OPTIMIZE test_schema.test_vector_batch_1773819304920;"
+   - "OPTIMIZE sql帮我手动执行一下"
+   - 以上属于 SQL 执行请求，不是 Job 性能诊断，请走 SQL 执行工具
+
+**⚠️ 重要说明**：
+- 优化参数推荐必须遵守的原则 `references/optimization-principles.md`
+
+## 架构设计

+# Job 性能分析核心规范
+
+本文档定义 Job 性能分析的核心流程和原则。
+
+## 1. 输入说明
+
+**输入文件**：
+- `plan.json` - **必需**，执行计划（DAG、Operator、算法类型）
+- `job_profile.json` - **可选**，运行时统计（耗时、数据量、DOP）
+
+**关键原则**：
+- 完整分析需要两者结合
+- 仅从 profile 无法判断算法（如 Join 类型）
+- 仅从 plan 无法获取实际性能
+- **当 job_profile.json 为空或不提供时**：
+  - 部分分析（如增量状态表优化）仍可基于 plan.json 给出结果
+  - 涉及运行时性能数据的分析将无法执行
+  - 建议提供完整文件以获得最佳诊断效果
+
+## 2. 初始化步骤
+
+### 2.1 SQL 分类
+```python
+sql_text = plan['settings']['cz.sql.text']
+is_refresh = 'REFRESH' in sql_text.upper()
+```
+
+### 2.2 版本信息
+```python
+version = plan['build_info']['GitBranch']
+# ⚠️ 内部使用，不暴露给用户
+```
+
+### 2.3 VC 模式
+```python
+is_ap = plan['settings']['cz.inner.is.ap.vc'] == '1'
+# 0 = GP, 1 = AP
+
+# 获取 VC core 数
+if is_ap:
+    vc_cores = int(plan['settings']['cz.analyze.instance.executor.count'])
+else:
+    vc_cores = int(plan['settings']['cz.sql.gp.vc.capability']) // 100
+```
+
+### 2.4 已有参数
+```python
+settings = plan['settings']
+# ✅ 推荐前必须检查参数是否已存在
+# ❌ 不要推荐已存在且正确的参数
+```
+
+### 2.5 Stage 对齐
+```python
+for stage_id in plan['dml']['stages']:
+    if stage_id in profile['stageSummary']:
+        # 对齐成功
+```
+
+### 2.6 Operator 统计
+计算每个 operator：
+- 最大/平均耗时
+- Stage 占比
+- 总体占比
+- 倾斜比率（max/avg）
+
+### 2.7 选择分析策略
+
+根据 SQL 类型选择：
+- REFRESH → 错误分析（8） + 增量计算优化（4.1 + 4.2）
+- Compaction → TODO
+- GP job → TODO
+- AP job → TODO
+
+## 3. 核心原则
+
+### ❌ 禁止行为
+1. 不给无依据的参数
+2. 不凭空编造 flag
+3. 不推荐已存在且正确的参数
+4. 不说"没有发现问题"
+
+### ✅ 必须做到
+1. 每个建议必须有明确触发条件
+2. 每个建议必须有数据证据
+3. 推荐前必须检查参数是否已存在
+4. 必须主动分析所有慢 Stage
+
+## 4. 参数推荐逻辑
+
+```python
+def should_recommend(param_name, expected_value):
+    if param_name not in settings:
+        return True  # 参数不存在，推荐
+    
+    if settings[param_name] != expected_value:
+        return True  # 参数存在但值不对，推荐
+    
+    return False  # 参数已正确配置，不推荐
+```
+
+## 5. 输出格式
+
+### 必须包含
+- 发现的问题（附数据证据）
+- 参数建议（仅当问题存在）
+- 推理过程（引用实际数据）
+
+### 不要包含
+- 已配置的参数
+- 无依据的建议
+- 版本信息
+- 过度解释
+
+## 6. 工作流总结
+
+```
+输入 plan.json + job_profile.json
+  ↓
+初始化（2.1-2.7）
+  ↓
+选择策略
+  ↓ (REFRESH SQL)
+8. 错误分析（Job 冲突检测等）
+  ↓
+4.1 Stage/Operator 优化（8个子规则）
+  ↓
+4.2 状态表优化（7个子规则）
+  ↓
+生成报告（仅包含有依据的建议）
+```

+    155: 'KEY_PATH_END',                  # coordinator返回response给客户端

+    170: 'FINISHED',                      # persist结束

+
+#### 提取 Profiling 数据
+```python
+# 从 job_profile.json 提取
+profiling_data = profile_data['data']['jobSummary']['jobProfiling']['profiling']
+
+# 构建时间映射
+profiling_map = {}
+for entry in profiling_data:
+    event_id = int(entry['e'])
+    timestamp_ms = int(entry['t'])
+    profiling_map[event_id] = timestamp_ms
+
+# 示例数据结构:
+# [
+#   {"e": 100.0, "t": "1769626801341"},  # RECEIVE_SUBMIT
+#   {"e": 101.0, "t": "1769626801341"},  # PRECHECK_START
+#   {"e": 102.0, "t": "1769626801343"},  # PRECHECK_END
+#   ...
+# ]
+```
+
+#### 计算各阶段耗时
+```python
+def calculate_phase_durations(profiling_map):
+    """计算各阶段耗时（毫秒）- 按照官方定义"""
+    durations = {}
+    
+    # 1. Setup: SQL初始化阶段 (100 -> 108)
+    if 100 in profiling_map and 108 in profiling_map:
+        durations['setup'] = profiling_map[108] - profiling_map[100]
+    
+    # 2. Resuming Cluster: 启动VC (110 -> 112)
+    if 110 in profiling_map and 112 in profiling_map:
+        durations['resuming_cluster'] = profiling_map[112] - profiling_map[110]
+    
+    # 3. Queued: 等待资源 (112 -> 120)
+    if 112 in profiling_map and 120 in profiling_map:
+        durations['queued'] = profiling_map[120] - profiling_map[112]
+    
+    # 4. Running: SQL处理数据 (120 -> 130)
+    if 120 in profiling_map and 130 in profiling_map:
+        durations['running'] = profiling_map[130] - profiling_map[120]
+    
+    # 5. Finish: SQL结束 (130 -> 150)
+    if 130 in profiling_map and 150 in profiling_map:
+        durations['finish'] = profiling_map[150] - profiling_map[130]
+    
+    # 6. 总耗时 (100 -> 150)
+    if 100 in profiling_map and 150 in profiling_map:
+        durations['total'] = profiling_map[150] - profiling_map[100]
+    
+    return durations
+
+# 使用示例
+durations = calculate_phase_durations(profiling_map)
+running_time_ms = durations.get('running', 0)
+running_time_sec = running_time_ms / 1000
+```
+
+#### 关键阶段说明
+
+根据官方定义，Job 生命周期分为以下几个关键阶段：
+
+1. **Setup (100→108)**: SQL初始化阶段，包含编译优化等操作
+   - 正常情况下应该很快（< 2s）
+   - 如果耗时较长，可能是SQL过于复杂
+
+2. **Resuming Cluster (110→112)**: 等待启动VC
+   - 正常情况下应该很快（< 1s）
+   - 如果长时间未拉起，请联系技术支持
+
+3. **Queued (112→120)**: 作业排队等待资源
+   - 正常情况下应该很快（< 5s）
+   - 如果耗时较长，建议查看vc资源是否占满，考虑扩容vc
+
+4. **Running (120→130)**: SQL处理数据时间
+   - 这是核心计算阶段，通常占总时间的大部分
+   - 可以点到诊断查看每个算子耗时
+
+5. **Finish (130→150)**: SQL结束时间
+   - 包含commit数据、auto merge等操作
+   - 正常情况下应该较快
+
+#### 实际案例分析

+
+### Stage 统计
+```python
+profile = profile_data['data']['jobSummary']
+
+for stage_id, stage_data in profile['stageSummary'].items():
+    # 时间
+    start = int(stage_data['startTime'])
+    end = int(stage_data['endTime'])
+    elapsed_ms = end - start
+    
+    # DOP
+    dop = 0
+    for count in stage_data['taskCountDetail'].values():
+        dop += int(float(count))
+    
+    # IO 统计
+    io = stage_data['inputOutputStats']
+    input_bytes = int(io['inputBytes'])
+    output_bytes = int(io['outputBytes'])
+    spill_bytes = int(io['spillingBytes'])
+```
+
+### Operator 统计
+```python
+# Operator 性能
+for op_id, op_data in stage_data['operatorSummary'].items():
+    # 耗时
+    wall_time = op_data['wallTimeNs']
+    max_ns = int(wall_time['max'])
+    avg_ns = int(wall_time['avg'])
+    
+    max_ms = max_ns / 1_000_000
+    avg_ms = avg_ns / 1_000_000
+    
+    # 倾斜比率
+    skew = max_ms / avg_ms if avg_ms > 0 else 1.0
+    
+    # Spilling
+    if 'spillStats' in op_data:
+        spill = op_data['spillStats']
+        # 详细的 spill 信息
+```
+
+## 常用计算模式
+
+### 计算占比
+```python
+# Stage 占总体百分比
+stage_pct = (stage_elapsed_ms / total_job_time) * 100
+
+# Operator 占 Stage 百分比
+op_pct = (op_max_ms / stage_elapsed_ms) * 100
+```
+
+### 判断触发条件
+```python
+# 耗时阈值
+is_slow = elapsed_ms > 12000 or (elapsed_ms / total_time * 100) > 15
+
+# DOP 差异
+dop_ratio = current_dop / upstream_dop
+is_dop_diff = dop_ratio < 0.5
+
+# 数据量阈值
+data_gb = bytes / (1024**3)
+is_large = data_gb > 10
+```
+
+### 搜索 Pattern
+```python
+# 使用 JSON 字符串搜索
+plan_str = json.dumps(stage)
+
+# Join 算法
+is_broadcast = 'BroadcastHashJoin' in plan_str or 'Broadcast' in plan_str
+is_shuffle = 'ShuffleHashJoin' in plan_str
+
+# Aggregate 阶段
+has_p1 = 'P1' in plan_str or 'PARTIAL1' in plan_str
+is_complete = 'COMPLETE' in plan_str
+
+# 高成本函数
+has_expensive = any(f in plan_str for f in 
+    ['MULTI_RANGE_COLLECT', '_DF_BF_COLLECT', 'BF_COLLECT'])
+
+# TableSink
+has_tablesink = 'TableSink' in plan_str
+is_overwrite = 'OVERWRITE' in plan_str
+is_delta = 'PhysicalTableSink_DELTA' in plan_str
+```
+
+## 典型分析示例
+
+### 找瓶颈 Operator
+```python
+# 按耗时排序
+sorted_ops = sorted(operator_analysis, 
+                   key=lambda x: x['max_time_ms'], 
+                   reverse=True)
+
+bottleneck = sorted_ops[0]
+```
+
+### 计算上游 DOP
+```python
+upstream_dops = [
+    stage_metrics[sid]['dop'] 
+    for sid in stage_metrics 
+    if sid != current_stage_id
+]
+max_upstream_dop = max(upstream_dops) if upstream_dops else 0
+```
+
+### 检查参数是否已存在
+```python
+def should_recommend(param, value):
+    if param not in settings:
+        return True
+    if settings[param] != value:
+        return True
+    return False
+```
+
+## 常见陷阱
+
+### ❌ 错误做法
+```python
+# 仅从 profile 判断 Join 类型
+# profile 中没有算法信息！
+join_type = ???  # 无法获取
+
+# 忽略参数检查
+optimizations.append(...)  # 可能重复推荐
+```
+
+### ✅ 正确做法
+```python
+# 从 plan 获取算法
+plan_str = json.dumps(stage['operators'])
+is_broadcast = 'BroadcastHashJoin' in plan_str
+
+# 从 profile 获取性能
+elapsed = stage_data['endTime'] - stage_data['startTime']
+
+# 检查参数
+if 'cz.optimizer.enable.broadcast.hash.join' not in settings:
+    recommend(...)
+```

+# 错误分析规范
+
+本文档定义 Job 错误分析的规则和处理方法。
+
+## 8. 报错分析
+
+### 8.0 错误信息收集器
+
+**目标**：统一从 job_profile.json 的所有 message 字段收集错误信息，去重并精炼，为后续错误分析提供基础。
+
+#### 设计原则
+
+1. **统一收集**：从 Job、Stage、Task 三个层级收集所有错误信息
+2. **去重精炼**：可能有重复的错误信息，需要去重和精炼
+3. **分类标注**：对错误信息进行分类（冲突、超时、内存等）
+4. **基础服务**：为后续的具体错误分析规则（如 8.1）提供数据基础
+
+#### 收集位置
+
+1. **Job 级别**：`data.jobStatus.message`
+2. **Stage 级别**：`data.jobSummary.stageSummary[stage_id].message`
+3. **Task 级别**：`data.jobSummary.stageSummary[stage_id].taskSummary[task_id].message`
+
+#### 错误识别
+
+通过关键字识别错误信息：
+- error, exception, failed, failure
+- conflict, timeout, abort, cancel
+- invalid, illegal, denied, forbidden
+- out of memory, oom, overflow
+- not found, unauthorized
+
+#### 去重策略
+
+- 使用消息内容作为去重 key
+- 完全相同的消息只保留第一个
+- 保留原始消息和精炼后的消息
+
+#### 输出格式
+
+```python
+{
+    'error_messages': [
+        {
+            'location': 'job_status' | 'stage' | 'task',
+            'stage_id': 'xxx',  # 如果是 stage/task 级别
+            'task_id': 'xxx',   # 如果是 task 级别
+            'message': '原始消息',
+            'refined_message': '精炼后的消息（截断过长内容）',
+            'raw_message': '完整原始消息'
+        }
+    ]
+}
+```
+
+#### 存储到 Context
+
+收集的错误信息存储到 `context['error_messages']`，供后续规则使用：
+- `context['error_messages']`：精炼后的错误列表
+- `context['raw_error_messages']`：原始错误列表
+
+#### Insight 输出
+
+```
+收集到 X 条错误信息（去重后 Y 条），涉及 Z 个位置。
+错误类型: 冲突错误, 超时错误, ...
+```
+
+### 8.1 提交冲突报错检测
+
+**目标**：基于 ErrorMessageCollector 收集的错误信息，检测提交冲突错误并给出重跑建议。
+
+#### 依赖关系
+
+此规则依赖于 ErrorMessageCollector（8.0），必须在错误收集器之后执行。
+
+#### 检测逻辑
+
+从 `context['error_messages']` 中查找包含以下特征的错误信息：
+
+```
+"this job has conflicts with another concurrent job which updates"
+```
+
+#### 数据来源
+
+不直接访问 job_profile.json，而是使用 ErrorMessageCollector 收集的错误信息：
+
+```python
+error_messages = context.get('error_messages', [])
+for error in error_messages:
+    if 'conflicts with another concurrent job which updates' in error['message'].lower():
+        # 检测到冲突
+```
+
+#### 输出结果
+
+**Finding**:
+- type: `job_conflict_error`
+- severity: `high`
+- title: "Job 提交冲突错误"
+- description: 详细的冲突信息，包括所有发现冲突的 Stage 和 Task
+- evidence: 冲突详情列表
+
+**Recommendation**:
+- type: `rerun_job`
+- priority: `high`
+- title: "重新运行整个 Job"
+- description: 建议重新提交并运行此 Job
+- action: "重新提交并运行此 Job"
+
+**Insight**:
+- category: `error_analysis`
+- message: 冲突统计信息和原因说明
+
+#### 解决方法
+
+**唯一解决方案**：重新运行整个 Job
+
+**原因说明**：
+- 提交冲突通常发生在多个 Job 并发更新同一张表时
+- 系统无法自动解决此类冲突
+- 重跑可以让 Job 在新的时间点重新执行，避免冲突
+
+#### 实现要点
+
+1. **依赖关系**：必须在 ErrorMessageCollector 之后执行
+2. **数据来源**：从 `context['error_messages']` 获取数据，不直接访问 profile
+3. **优先级**：错误分析应在其他优化分析之前执行
+4. **清晰性**：输出应明确指出错误发生的位置（Job Status / Stage / Task）
+5. **架构优势**：
+   - 解耦：冲突检测不需要知道数据结构细节
+   - 复用：其他错误分析规则也可以使用收集的错误信息
+   - 扩展：新增错误类型只需添加新规则，不需要重复收集逻辑
+
+#### 代码示例
+
+```python
+class JobConflictDetection(BaseRule):
+    """检测 Job 提交冲突错误"""
+    
+    name = "job_conflict_detection"
+    category = "error_analysis"
+    
+    def analyze_global(self, context: Dict) -> Dict:
+        # 从 context 中获取收集的错误信息
+        error_messages = context.get('error_messages', [])
+        
+        # 查找冲突错误
+        conflict_errors = []
+        for error in error_messages:
+            message = error.get('message', '')
+            if 'conflicts with another concurrent job which updates' in message.lower():
+                conflict_errors.append(error)
+        
+        # 生成 findings 和 recommendations
+        if conflict_errors:
+            # 构建详细的错误信息
+            # ...
+```
+
+#### 注意事项
+
+1. **不要过度分析**：发现冲突后，直接建议重跑，不需要深入分析冲突原因
+2. **不要给其他建议**：对于冲突错误，重跑是唯一解决方案，不要给出其他优化建议
+3. **检查 profile 数据**：如果 job_profile.json 为空或无效，跳过此规则
+4. **大小写不敏感**：检查时使用 `.lower()` 确保不遗漏任何格式的错误信息
+
+## 未来扩展
+
+后续可以添加更多错误分析规则，都基于 ErrorMessageCollector 收集的错误信息：
+
+### 8.2 内存溢出错误（OOM）
+- 检测关键字：`out of memory`, `oom`
+- 解决方案：增加内存配置、优化数据倾斜
+
+### 8.3 超时错误
+- 检测关键字：`timeout`
+- 解决方案：增加超时时间、优化查询性能
+
+### 8.4 权限错误
+- 检测关键字：`denied`, `forbidden`, `unauthorized`
+- 解决方案：检查权限配置
+
+### 8.5 数据格式错误
+- 检测关键字：`invalid`, `illegal`, `format`
+- 解决方案：检查数据格式、修复数据
+
+### 架构优势
+
+所有错误分析规则共享同一个错误收集器：
+1. **统一收集**：ErrorMessageCollector 统一收集所有错误
+2. **按需分析**：各个具体规则从收集的错误中筛选自己关心的类型
+3. **易于扩展**：新增错误类型只需添加新规则，不需要修改收集逻辑
+4. **性能优化**：只遍历一次 profile 数据，所有规则共享结果
+
+### 规则模板
+
+```python
+class NewErrorDetection(BaseRule):
+    """检测新类型错误"""
+    
+    name = "new_error_detection"
+    category = "error_analysis"
+    
+    def analyze_global(self, context: Dict) -> Dict:
+        # 从 context 获取收集的错误
+        error_messages = context.get('error_messages', [])
+        
+        # 筛选特定类型的错误
+        target_errors = [
+            error for error in error_messages
+            if 'keyword' in error['message'].lower()
+        ]
+        
+        # 生成 findings 和 recommendations
+        # ...
+```
+
+每个错误类型应该：
+1. 有明确的检测逻辑（关键字匹配）
+2. 给出具体的解决方案
+3. 提供足够的上下文信息
+4. 按照统一的输出格式
+5. 基于 ErrorMessageCollector 的结果
+
+## 已实现的错误分析规则
+
+### 8.1 提交冲突错误检测（JobConflictDetection）
+
+**关键字**：`conflicts with another concurrent job which updates`
+
+**解决方案**：重新运行整个 Job
+
+**输出**：
+- Finding: job_conflict_error
+- Recommendation: rerun_job (type)
+
+### 8.2 优化器错误检测（OptimizerErrorDetection）
+
+**关键字**：`optimizer internal error`
+
+**解决方案**：
+1. 如果未设置 `cz.sql.playback.scratch=true`，建议设置此参数
+2. 重新运行 Job 生成 playback 信息
+3. 收集 playback 信息用于问题诊断
+
+**输出**：
+- Finding: optimizer_internal_error
+- Recommendation: 设置 cz.sql.playback.scratch=true (parameter type)
+
+**特殊处理**：
+- 检查 settings 中是否已设置 playback 参数
+- 如果已设置，不重复推荐，但提示收集 playback 信息
+
+**代码示例**：
+```python
+class OptimizerErrorDetection(BaseRule):
+    def analyze_global(self, context: Dict) -> Dict:
+        error_messages = context.get('error_messages', [])
+        optimizer_errors = [
+            e for e in error_messages
+            if 'optimizer internal error' in e['message'].lower()
+        ]
+        
+        if optimizer_errors:
+            settings = context.get('settings', {})
+            playback_enabled = settings.get('cz.sql.playback.scratch', '').lower() == 'true'
+            
+            if not playback_enabled:
+                # 推荐设置 playback 参数
+                recommendations.append({
+                    'type': 'parameter',
+                    'setting': 'cz.sql.playback.scratch',
+                    'value': 'true',
+                    'priority': 'high',
+                    'impact': 'DIAGNOSTIC',
+                    'reason': '生成 playback 信息以帮助定位优化器问题'
+                })
+```

+# 增量算法分析指南
+
+本文档包含增量计算的算法识别和分析规则。
+
+这是增量优化的核心部分，用于识别和分析增量算法，为状态表优化提供基础。
+
+**相关文档**：
+- [Stage/Operator 优化](./stage-operator-optimization.md) - Stage 和 Operator 级别优化
+- [状态表优化](./state-table-optimization.md) - 状态表相关优化规则（依赖本文档的分析结果）
+- [优化原则](./optimization-principles.md) - 参数推荐原则
+
+---
+
+## 状态表优化前提
+
+**⚠️ 重要：启用条件**
+
+状态表优化分析**默认禁用**，只有在以下情况下才会执行：
+- 用户在 prompt 中**明确提到**需要"状态表优化"
+- 命令行使用 `--enable-state-table` 参数
+
+**原因**：根据 prompt 4.2.0 的要求，如果用户没有提到使用状态表优化，则不需要使用下面的优化原则来优化。
+
+**使用方式**：
+```bash
+# 禁用状态表分析（默认）
+cz-analyze-job plan.json job_profile.json
+
+# 启用状态表分析
+cz-analyze-job plan.json job_profile.json --enable-state-table
+```

+## 增量算法分析
+
+### 4.2.1 判断是否增量刷新及增量算法分析
+
+**目的**：确认当前 job 是否为增量刷新，并识别增量算法
+
+本节包含四个子步骤（4.2.1.1-4.2.1.4），对应增量算法的完整分析流程。
+
+#### 4.2.1.1 识别所有 operator 是 delta 还是 snapshot
+
+**第一步：判断是否增量刷新**
+使用 **4.1.1** 的方法判断。
+
+**第二步：识别增量数据**（仅当是增量 plan 时）
+如果是增量计算的 plan，需要收集哪些表是增量数据，哪些是读 snapshot。
+
+**数据提取**：
+```python
+# 从 TableScan operator 中获取 incrementalTableProperty
+table_scan = operator['tableScan']
+incr_property = table_scan.get('incrementalTableProperty', {})
+from_version = incr_property.get('from')
+to_version = incr_property.get('to')
+```
+
+**版本号含义**：
+
+`incrementalTableProperty` 有 `from/to` 字段，记录了版本范围：
+
+| from | to | 含义 | 说明 |
+|------|-----|------|------|
+| 28800 | 57600 | **Delta 数据** | 从版本 28800 到 57600 的增量数据 |
+| -9223372036854775808 | 28800 | **上个 Snapshot** | 版本 28800 的完整状态（上个状态） |
+| -9223372036854775808 | 57600 | **当前 Snapshot** | 版本 57600 的完整状态（当前状态） |
+
+**判断规则**（根据 original_prompt.md 第 49 行）：
+- **Delta 数据**：只有当 `from` 和 `to` 都是非 MIN_LONG 值时（如 `from=28800, to=57600`）
+- **Snapshot 数据**：`from=-9223372036854775808`（MIN_LONG）是明显特征
+
+**增量计算公式**：
+```
+上个 Snapshot (from=-9223372036854775808, to=28800) + Delta (from=28800, to=57600) = 当前 Snapshot (from=-9223372036854775808, to=57600)
+```
+
+**示例**：
+```python
+# 示例 1: Delta 数据
+{
+  "from": "28800",
+  "to": "57600",
+  "fromMetaVersion": "0",
+  "toMetaVersion": "0"
+}
+# → 这是从 28800 到 57600 的增量数据（from 和 to 都不是 MIN_LONG）
+
+# 示例 2: 上个 Snapshot
+{
+  "from": "-9223372036854775808",
+  "to": "28800",
+  "fromMetaVersion": "0",
+  "toMetaVersion": "0"
+}
+# → 这是版本 28800 的完整状态（from 是 MIN_LONG）
+
+# 示例 3: 当前 Snapshot
+{
+  "from": "-9223372036854775808",
+  "to": "57600",
+  "fromMetaVersion": "0",
+  "toMetaVersion": "0"
+}
+# → 这是版本 57600 的完整状态（from 是 MIN_LONG）
+```
+
+**第三步：Delta/Snapshot 传播规则**
+
+通过分析算子的输入输出，自动推导每个算子处理的是 delta 还是 snapshot 数据。
+
+**传播规则**：
+
+1. **一元算子**（Filter, Project, Calc 等）：
+   - 输入是 delta → 输出是 delta
+   - 输入是 snapshot → 输出是 snapshot
+   ```
+   Filter(delta) = delta
+   Filter(snapshot) = snapshot
+   ```
+
+2. **Join 算子**：
+   - **只有** left 和 right **都是 snapshot**，结果才是 snapshot
+   - 其他情况（有任何一个是 delta）结果都是 delta
+   ```
+   Join(snapshot, snapshot) = snapshot
+   Join(delta, snapshot) = delta
+   Join(snapshot, delta) = delta
+   Join(delta, delta) = delta
+   ```
+
+3. **Union 算子**：
+   - 所有输入都是 snapshot → 输出是 snapshot
+   - 所有输入都是 delta → 输出是 delta
+   - 部分 delta，部分 snapshot → 输出是 snapshot（但这种情况很少见）
+   ```
+   Union(snapshot, snapshot, ...) = snapshot
+   Union(delta, delta, ...) = delta
+   ```
+
+4. **其他多元算子**：
+   - 一般按照 Union 规则处理
+   - 如果遇到特殊情况，需要单独分析
+
+5. **⚠️ 增量算法 Hint 优先规则**（重要补充）：
+   - **如果算子有增量算法 hint**（如 `IncrementalJoinRule`, `IncrementalAggregateRule` 等），**该算子应该被标记为 delta**
+   - 这是因为增量算法是用来处理增量数据的，即使输入是 snapshot，增量算法也会输出 delta
+   - **增量算法的语义**：可以接受 SNAPSHOT 输入并产生 DELTA 输出（通过比较两个 snapshot 计算差异）
+   - **检查方法**：在算子的 JSON 中查找 `Incremental` 或 `DeltaState` 关键字
+   - **优先级**：增量 hint 检查应该在基于输入的传播规则之前执行
+
+   ```python
+   # 示例：HashJoin 有增量 hint
+   if 'Incremental' in json.dumps(operator) or 'DeltaState' in json.dumps(operator):
+       operator_type = DataType.DELTA  # 直接标记为 delta
+   else:
+       # 使用基于输入的传播规则
+       operator_type = infer_from_inputs(...)
+   ```
+
+   **实际案例**：
+   ```
+   HashJoin30 (有 IncrementalJoinWithoutCondenseRule hint)
+   ├── ShuffleRead31 → SNAPSHOT (来自 snapshot TableScan)
+   └── ShuffleRead92 → DELTA (来自 delta TableScan)
+
+   结果：HashJoin30 = DELTA（因为有增量 hint，而不是基于输入判断）
+   ```
+
+#### 4.2.1.2 识别不同算子的增量算法
+
+**目的**：识别不同算子的增量算法，区分真正的 join/aggregate/window 增量算子和算法的一部分
+
+##### Rule Hint 解析
+
+增量算法会在算子上添加 Rule hint，用于标识算子属于哪个增量算法。
+
+**Rule Hint 格式**：
+
+1. **不带 ID 的 Rule**：
+   ```
+   Rule:IncrementalLinearFunctionAggregateRule
+   ```
+   - 表示这是增量 Aggregate 算法的一部分
+   - Rule 名称包含算子类型（Aggregate/Join/Window）
+
+2. **带 ID 的 Rule**：
+   ```
+   Rule:IncrementalJoinWithoutCondenseRule_cz::optimizer::LogicalJoin#31766417
+   ```
+   - `LogicalJoin#31766417` 是算子 ID
+   - 所有带相同 ID 的算子都是为了计算同一个 Join 的增量算法
+   - 用于识别增量算法的边界
+
+3. **HINT= 格式（新增，包含 DeltaState 信息）**：
+   ```
+   HINT=delta,DeltaState:[1,1896] - [1,6393]_IncrementalWindowSetDeltaRule#cz::optimizer::Window#293342
+   ```
+   - `HINT=delta` 表示计算 delta 数据来优化
+   - `DeltaState:[1,1896] - [1,6393]` 表示该算子是整体增量算法的状态算子
+   - `IncrementalWindowSetDeltaRule` 是使用的增量算法
+   - `Window#293342` 表示是对哪个算子计算了增量算法
+   - 这种 hint 提供了更详细的状态信息，用于识别增量算法的状态边界
+
+4. **⚠️ DeletePlan Rule（必须作为边界终止遍历）**：
+   ```
+   Rule:DeletePlan-delta-join(left)_Delta:L_Snapshot:R
+   ```
+   - **DeletePlan 相关的 hint 不属于任何增量算法**
+   - 这些 hint 用于表示删除数据的 plan
+   - **在识别增量算法时的处理**：
+     - **解析阶段**：过滤掉所有包含 `DeletePlan` 的 Rule hint（不作为算法起点）
+     - **遍历阶段**：如果在执行路径中遇到 DeletePlan 算子，**必须终止遍历**
+   - **为什么必须终止而不是跳过**：
+     - DeletePlan 算子在执行路径中表示删除操作
+     - 如果跳过 DeletePlan 继续查找，找到的 subplan 会缺少中间算子（不完整）
+     - 由于 plan 是执行路径不能跳过，所以遇到 DeletePlan 必须终止
+
+**Rule Hint 的作用**：
+
+- **识别算法类型**：从 Rule 名称判断是 Aggregate/Join/Window 算法
+- **识别算法边界**：通过 ID 找到属于同一个算法的所有算子
+- **区分原始算子**：
+  - 如果 Rule 出现在对应类型的算子上（如 Aggregate Rule 在 Aggregate 算子上）→ 原始 SQL 算子
+  - 如果 Rule 出现在其他类型的算子上（如 Aggregate Rule 在 Join 算子上）→ 算法辅助算子
+- **处理 DeletePlan 算子**：
+  - **解析阶段**：包含 `DeletePlan` 的 Rule hint 不作为算法起点
+  - **遍历阶段**：遇到 DeletePlan 算子作为边界条件，终止遍历
+
+#### 4.2.1.3 算子增量算法对应的 subplan
+
+**目的**：找到一个增量算法对应的所有算子，识别算子对应的 root 阶段
+
+**⚠️ 重要说明**：
+
+1. **完整的执行 subplan，不是零散的 hint operator**：
+   - 算子增量算法对应的 subplan **不是**让你把 rule 相同的合在一起
+   - rule 相同的算子肯定来源于同一个算子对应的增量算法
+   - 而是要把某一个增量算法涉及到的**所有算子**都包含起来
+   - 这些算子**不一定有 Rule 这些 hint**
+   - 他们是一个执行的 subplan，而不是这些零散的 hint operator 组成
+
+   **示例**：
+   ```
+   假设有增量 Aggregate 算法：
+   - TableScan (delta) - 没有 Rule hint，但是算法的输入
+   - TableScan (snapshot) - 没有 Rule hint，但是算法的输入
+   - Join - 有 Rule hint（为 Aggregate 准备数据）
+   - Calc - 没有 Rule hint，但在算法执行路径中
+   - Aggregate (P1) - 有 Rule hint
+   - Aggregate (P2) - 有 Rule hint
+   - Aggregate (Final) - 有 Rule hint
+
+   完整 subplan 应该包含所有 7 个算子，而不仅仅是有 hint 的 4 个算子
+   ```
+
+2. **使用 plan.json 的实际 operator ID，不是数组索引**：
+   - 在 plan.json 里找到所有 operator 对应的 Id
+   - 注意这里的 **ID 不是代码中那些 index 下标**
+   - 应该使用 plan.json 中算子对象的 `"id"` 字段的实际值
+   - 例如：`"id": "12345"` 应使用 `"12345"` 而不是数组索引 `0`
+
+3. **⚠️ 处理没有 ID 的 Rule Hint（新增逻辑 - 两阶段方法）**：
+
+   根据 4.2.1.2 找到相同增量算法的算子后，需要采用**两阶段方法**来构建完整的 subplan：
+
+   **阶段1：构建初始确定集合（在 `_parse_rule_hints()` 中完成）**
+
+   目的：复用 4.2.1.2 的逻辑，找到所有带hint的算子（有ID和无ID），形成确定集合
+
+   **步骤 1.1：解析有ID的hint**
+   - 格式：`Rule:IncrementalAggregateSetDeltaRuleV2#5402883`
+   - 存储在 `self.rule_groups` 中：`{algorithm_id: [operator_indices]}`
+
+   **步骤 1.2：解析无ID的hint**
+   - 格式：`HINT=Rule:IncrementalAggregateSetDeltaRuleV2_Delta:R_Snapshot:L`
+   - 存储在 `self.operator_rule_names` 中：`{operator_index: rule_name}`
+
+   **步骤 1.3：匹配无ID的hint到算法**
+   - 调用 `_assign_hints_without_id_to_algorithms()`
+   - 对于每个无ID的hint，向下游查找匹配的算法
+   - **关键**：匹配条件是 **算子类型相同 AND rule名称相似**
+   - 使用 `_find_matching_algorithm_downstream_by_name()` 进行匹配：
+     - 提取基础rule名称（去除版本号V2等）
+     - BFS向下游搜索
+     - 找到第一个算子类型和rule名称都匹配的算法
+   - 将匹配的算子加入对应算法的 `rule_groups`
+
+   **阶段2：从确定集合扩展到完整subplan（在 `_identify_incremental_algorithms_with_subplan()` 中完成）**
+
+   目的：从确定集合（rule_groups）出发，使用边界规则遍历上下游，得到完整的subplan
+
+   **⚠️ 重要：使用两个独立的循环**
+
+   根据用户反馈："应该先全部遍历一遍增量算法，得到所有的确定性的相关subplan后，再继续后续操作"
+
+   **第一个循环：为所有算法构建确定集合**
+   - 遍历所有算法
+   - 对每个算法调用 `_connect_hint_operators_for_algorithm()`
+   - 找到所有hint算子之间的连通路径
+   - 存储所有算法的确定集合
+
+   **第二个循环：从确定集合扩展到完整subplan**
+   - 遍历所有算法
+   - 使用第一个循环构建的确定集合
+   - 调用 `_find_algorithm_subplan_from_confirmed_set()` 扩展
+   - 使用边界规则判断是否继续添加算子
+
+   **步骤 2.1：第一个循环 - 构建所有确定集合**
+   - 调用 `_connect_hint_operators_for_algorithm()` 为每个算法
+   - 找到所有hint算子之间的连通路径
+   - 根据 prompt："这些算子联通(遍历)起来的算子一定属于该算法的subplan一部分"
+   - 例如：如果有 hint 算子 A 和 D，且它们之间有路径 A→B→C→D，则 B 和 C 也属于确定集合
+   - 存储在 `all_confirmed_sets` 字典中
+
+   **步骤 2.2：第二个循环 - 扩展到完整subplan**
+   - 使用第一个循环构建的确定集合作为起点
+   - 这些算子已经包含了有ID和无ID的hint算子，以及它们之间的连通路径
+
+   **步骤 2.3：调用 `_find_algorithm_subplan_from_confirmed_set()`**
+   - 从确定集合的每个算子出发
+   - 向上游和下游遍历
+   - 使用边界规则判断是否继续添加算子
+
+   **步骤 2.4：得到完整subplan**
+   - 确定集合 + 扩展的算子 = 完整subplan
+   - 直到所有方向都遇到边界为止
+
+   **代码实现要点**：
+   ```python
+   # ========== 阶段1：在 _parse_rule_hints() 中完成 ==========
+   def _parse_rule_hints(self):
+       # 1. 解析有ID的hint → 存入 rule_groups

+           )
+
+           all_confirmed_sets[rule_id] = {

+       for rule_id, rule_op_indices in sorted_rule_groups:
+           algo_info = all_confirmed_sets[rule_id]
+           confirmed_set = algo_info['confirmed_set']

+               algorithm_type=algo_type,
+               current_rule_id=rule_id,
+               operator_hint_map=operator_hint_map,
+               assigned_operators=assigned_operators
+           )
+
+   def _connect_hint_operators_for_algorithm(self, hint_operators, algorithm_type,

+       hint_list = list(hint_operators)
+
+       # 找到所有hint算子之间的连通路径
+       for i in range(len(hint_list)):
+           for j in range(i + 1, len(hint_list)):
+               idx1, idx2 = hint_list[i], hint_list[j]

+                   confirmed_set.update(path_operators)
+
+       return confirmed_set
+   ```
+
+   **重要性**：
+   - **两阶段方法确保了准确性**：先确定哪些算子肯定属于该算法，再扩展
+   - **处理无ID的hint**：通过向下游查找，将无ID的hint正确归属到对应算法
+   - **连通图保证完整性**：所有hint算子之间的路径都被包含，避免遗漏
+   - **边界规则控制范围**：从确定集合扩展时，边界规则防止跨算法包含
+
+##### 增量算法识别流程
+
+**自动识别步骤**：
+
+1. **识别 TableScan 数据类型**（4.2.1.1）
+   - 解析 `incrementalTableProperty` 的 from/to 字段
+   - 标记每个 scan 是 delta 还是 snapshot
+
+2. **解析 Rule Hints**（4.2.1.2）
+   - 提取所有 Rule hint
+   - **⚠️ 过滤 DeletePlan hint**：忽略所有包含 `DeletePlan` 的 Rule hint（不作为算法起点）
+   - 按照 Rule ID 分组算子
+   - 识别算法类型（Aggregate/Join/Window）
+
+3. **构建算子依赖关系**（4.2.1.3）
+   - 分析算子的输入输出关系
+   - 构建依赖图
+   - 使用 plan.json 的 "id" 字段表示每个算子的唯一 id
+
+4. **传播数据类型**（4.2.1.1）
+   - 从 TableScan 开始，按照传播规则推导每个算子的数据类型
+   - 迭代直到所有算子的类型都确定
+
+5. **识别增量算法边界**（4.2.1.2 & 4.2.1.3）
+   - 根据 Rule ID 分组找到每个增量算法的所有算子
+   - 区分原始 SQL 算子和算法辅助算子
+   - 找到每个增量算法的 root 算子（最上层算子）
+
+**示例**：
+
+假设有以下 plan：
+```
+TableScan(delta) → Join → Aggregate(P1) → Aggregate(P2) → Aggregate(Final)
+                     ↑
+TableScan(snapshot) ─┘
+```
+
+分析结果：
+- TableScan1: delta
+- TableScan2: snapshot
+- Join: delta（因为有一个输入是 delta）
+- Aggregate(P1): delta（输入是 delta）
+- Aggregate(P2): delta（输入是 delta）
+- Aggregate(Final): delta（输入是 delta）
+
+如果 Aggregate(P1/P2/Final) 都有 `Rule:IncrementalAggregateRule#12345`：
+- 这三个 Aggregate 都是为了计算同一个 Aggregate 的增量算法
+- 其中 Aggregate(Final) 是原始 SQL 的 Aggregate
+- Aggregate(P1/P2) 是算法辅助算子（3阶段聚合的中间阶段）
+
+##### 边界条件（重要）
+
+在查找增量算法的 subplan 时，必须设置严格的边界条件以避免跨算法包含。
+
+**⚠️ 关键区别**：不同边界条件对 subplan 的处理方式不同：
+- **排除边界**：不添加到 subplan，直接返回
+- **包含边界**：添加到 subplan，但终止遍历
+
+**边界条件**：
+
+1. **不同 hint 终止**（包含边界）：
+   - 碰到不是相同 hint 的算子，必须终止（避免将其他增量算法的算子包含进来）
+   - ✅ **添加到 subplan**，然后终止遍历
+
+2. **Aggregate Final/Complete 终止**（包含边界）：
+   - 对于 aggregate 算法，查找上游碰到 Final/Complete 状态也要终止（避免跨越算法边界）
+   - ✅ **添加到 subplan**，然后终止遍历
+
+3. **⚠️ DeletePlan 终止**（排除边界）：
+   - 如果遇到 DeletePlan 相关算子，必须终止遍历
+   - **原因**：DeletePlan 不属于任何增量算法
+   - **为什么不能跳过**：由于 plan 是执行路径，如果跳过 DeletePlan 继续查找，找到的 subplan 会缺少中间算子（不完整）
+   - ❌ **不添加到 subplan**，直接返回
+
+4. **⚠️ Snapshot 边界终止**（包含边界）：
+   - 向上游遍历时，如果当前算子是 snapshot 且上游也是 snapshot，必须终止遍历
+   - **原因**：snapshot 表示完整状态，其上游的 snapshot 不应该再属于增量算法一部分
+   - **为什么不能跳过**：由于 plan 是执行路径，如果跳过 snapshot 继续查找，找到的 subplan 会缺少中间算子（不完整）
+   - ✅ **添加到 subplan**，然后终止遍历
+   - **注意**：这个检查仅在向上游（输入）遍历时生效，向下游遍历不受影响
+
+5. **⚠️ Calc 边界终止**（包含边界）：
+   - 如果是 calc 有 hint，且 hint 包含了 DeltaState 和 Incremental，必须终止遍历
+   - **原因**：这种 calc 算子是某个增量算法的边界
+   - ✅ **添加到 subplan**，然后终止遍历
+
+6. **⚠️ DF Aggregate 终止**（排除边界）：
+   - 如果遇到 aggregate 算子，且聚集函数包括 MULTI_RANGE_COLLECT 或 _DF_BF_COLLECT，必须终止遍历
+   - **原因**：这是一个 DF (Dynamic Filter) 的 aggregate，仅仅是优化的一个 plan，不需要添加
+   - ❌ **不添加到 subplan**，直接返回
+   - **检查的聚集函数**：MULTI_RANGE_COLLECT, _DF_BF_COLLECT, DF_BF_COLLECT, BF_COLLECT
+
+##### 验证规则（重要）
+
+根据 prompt 4.2.1.3 第 60 行的要求，脚本会自动验证增量算法的正确性。这些验证规则用于检测脚本实现是否正确。
+
+**验证规则**：
+
+1. **算子唯一性**：同一个 operator 不应该属于两个不同的增量算法
+   - **例外**：root 节点或 TableScan 可以横跨多个增量算法
+   - **原因**：一个算子只能属于一个增量算法的执行路径（除了共享的输入源）
+
+2. **上下游冲突**：如果某个 operator 属于了上游的增量算法，就不应该属于下游的增量算法
+   - **原因**：增量算法的执行是有顺序的，算子不应该同时参与上下游的计算
+   - **例外**：TableScan 可以被多个算法共享
+
+3. **Snapshot 边界**：对于 snapshot 的算子，增量算法遍历时应该停止
+   - **原因**：snapshot 算子表示完整状态，其上游不应该再属于增量算法
+   - **检查**：如果算法包含 snapshot 算子，不应该继续向上游遍历到其他 snapshot 算子
+
+4. **DeletePlan 边界**：如果遇到 DeletePlan 算子，遍历应该已经终止
+   - **原因**：DeletePlan 不属于任何增量算法，不应该出现在增量算法的 subplan 中
+   - **检查**：如果增量算法的 subplan 包含 DeletePlan 算子，说明边界检测有问题
+
+5. **Top-Down 遍历检查**（根据 original_prompt.md 第 76 行）：从 root 节点开始 top-down 遍历，在碰到边界算子前不应该有其他增量算法的算子
+   - **原因**：如果在遍历路径中发现其他算法的算子，说明算法边界识别有问题
+   - **检查方法**：
+     - 从每个算法的 root 节点开始
+     - 向下游（输入方向）遍历
+     - 在遇到边界条件前，检查路径上的算子是否属于其他算法
+     - 如果有，说明算法识别有问题
+   - **边界条件**：与 subplan 查找时的边界条件一致（DeletePlan、不同 hint、Final/Complete、Snapshot 边界等）
+
+**验证警告输出**：
+
+如果检测到问题，脚本会在控制台输出验证警告：
+
+```
+[WARNING] 增量算法验证发现 4 个问题:
+  ⚠️  [算子唯一性] 算子 12345 属于 2 个不同的增量算法（非 root 节点且非 TableScan）: ...
+  ⚠️  [上下游冲突] 算子 67890 同时属于上游算法 IncrementalJoinRule#111 和下游算法 IncrementalAggregateRule#222
+  ⚠️  [Snapshot 边界] 算法 IncrementalAggregateRule#333 包含 snapshot 算子 op_100，但继续向上游遍历到 snapshot 算子 op_50
+  ⚠️  [Top-Down 遍历] 算法 IncrementalAggregateRule#444 从 root 节点遍历时，在碰到边界前发现算子 op_200 属于其他算法: IncrementalJoinRule#555
+```
+
+**重要提示**：
+
+- ⚠️ 这些是**验证规则**，不是告警
+- ⚠️ 如果不满足这些规则，说明**脚本有问题**，需要修改脚本实现
+- ⚠️ 验证警告表明增量算法识别逻辑可能存在错误，需要检查：
+  - `_find_algorithm_subplan_strict()` 的边界检测逻辑
+  - `_validate_algorithms()` 的验证逻辑
+  - 算子依赖关系的构建是否正确
+
+**代码位置**：
+
+验证逻辑实现在 `utils/incremental_algorithm_analyzer.py`：
+- `_validate_algorithms()` 方法：主验证入口，包含规则 1-4
+- `_validate_topdown_traversal()` 方法：规则 5 的实现（Top-Down 遍历检查）
+- `_topdown_traverse_and_check()` 方法：递归遍历并检查算子归属
+- `_is_boundary_operator()` 方法：判断边界条件
+
+##### TableScan Append-Only 信息收集
+
+**目的**：为每个增量算法收集所有 TableScan 算子的 append-only 信息
+
+根据 prompt 4.2.1.3.1 新增要求：
+> "每个增量算法得到了自己所有算子后，把所有tablescan算子找出来，
+> 如果全部是appendonly的tablescan，则显示出来，并标注；
+> 如果不全部是，也请显示每个tablescan是不是appendonly；
+> appendonly信息在4.2.1.5里已经得到，从这里拿"
+
+**实现方法**：
+
+在 `_identify_incremental_algorithms_with_subplan()` 方法中，为每个算法添加 `tablescan_append_only_info` 字段：
+
+```python
+def _collect_tablescan_append_only_info(self, subplan_indices: List[int]) -> Dict:
+    """
+    收集增量算法中所有 TableScan 算子的 append-only 信息
+

+
+**输出示例**：

+        "is_append_only": true
+      },

+        "is_append_only": false
+      }
+    ]
+  }
+}
+```
+
+**显示格式**：
+
+在增量算法分析结果中，会显示每个算法的 TableScan 信息：
+
+```
+增量算法: IncrementalAggregateSetDeltaRuleV2#5399145 (aggregate)
+  算子数量: 15
+  TableScan 信息:
+    - 包含 TableScan: True
+    - 总数: 2
+    - Delta TableScan: 1
+    - ✅ 所有 delta TableScan 都是 append-only (1/1)
+      - TableScan#12345 (delta, append_only) ✅
+    - 另有 1 个 snapshot TableScan (不参与 append-only 判断)
+      - TableScan#12346 (snapshot, N/A)
+```
+
+或者如果不是全部 append-only：
+
+```
+增量算法: IncrementalJoinWithoutCondenseRule#5398716 (join)
+  算子数量: 20
+  TableScan 信息:
+    - 包含 TableScan: True
+    - 总数: 3
+    - Delta TableScan: 2
+    - ⚠️  部分 delta TableScan 是 append-only (1/2)
+      - TableScan#12347 (delta, append_only) ✅
+      - TableScan#12348 (delta, with_delete) ⚠️
+    - 另有 1 个 snapshot TableScan (不参与 append-only 判断)
+      - TableScan#12349 (snapshot, N/A)
+```
+
+**重要说明**：
+- **只有 delta 类型的 TableScan 才有 append-only 的概念**
+- snapshot 类型的 TableScan 不参与 append-only 判断
+- `all_append_only` 字段表示"所有 delta TableScan 是否都是 append-only"
+- 显示时会明确区分 delta 和 snapshot TableScan
+
+**应用场景**：
+
+这个信息可以用于：
+1. **Window 优化（4.2.3）**：检查 window 输入是否全部是 append-only
+2. **Aggregate 复用（4.2.6）**：检查 aggregate 输入是否全部是 append-only
+3. **状态表优化（4.2.5）**：判断是否需要创建状态表
+4. **增量算法分析**：了解增量算法的输入数据特性
+
+#### 4.2.1.4 展示增量算法以及显示查看增量算法的状态信息/状态图等
+
+**目的**：可视化增量算法的依赖关系，展示哪些算子计算 aggregate/join/window
+
+##### 增量算法可视化
+
+生成增量算法依赖关系图，包括：
+- 每个增量算法的类型（Aggregate/Join/Window）
+- 算法包含的算子列表
+- 算法之间的依赖关系
+- 执行顺序（从上到下）
+- Root 算子标识
+
+##### 应用场景
+
+**状态表优化规则使用**：
+
+**重要前提**：关于状态表这些优化必须是对应算子的对应增量算法，如 aggregate 则必须是增量算法产生的，join/window 等都类似；可以根据 4.2.1.2 来判断。
+
+1. **aggregate_reuse 规则**：
+   - 只检查原始 SQL 的 Aggregate
+   - 过滤掉算法辅助的 Aggregate（P1/P2 阶段）
+   - **必须检查 aggregate 是否有增量 hint**（根据 4.2.1.2）：
+     - 检查是否包含 `IncrementalLinearFunctionAggregateRule` 等 Rule hint
+     - 检查是否包含 `HINT=delta,DeltaState:...` 等新格式 hint
+     - 如果没有增量 hint，说明不是原始 SQL 的 aggregate，跳过
+
+2. **state_table_enable 规则**：
+   - 只为原始 SQL 的算子建议状态表
+   - 不为算法辅助算子建议状态表
+   - **必须验证算子属于增量算法**（根据 4.2.1.2）
+
+3. **其他规则**：
+   - 类似地区分 Join/Window 的原始算子和辅助算子
+   - 所有状态表优化都必须基于增量算法识别（4.2.1.2）
+
+#### 4.2.1.5 算子 delta 是否为 append-only（纯增）
+
+**目的**：判断 delta 数据是否为 append-only（纯增，没有删除），用于后续优化决策
+
+**判断规则**：
+
+1. **TableScan 算子**：
+   - 检查是否输出 `__incremental_deleted` 列（注意是过去式）
+   - 检查位置：算子的实际输出列（`operator.schema.structTypeInfo.fields`），而不是表定义的完整schema
+   - **如果输出** → delta 不是纯增（有删除）
+   - **如果没有输出** → delta 是纯增
+
+   ```python
+   # 获取算子实际输出的列
+   operator_schema = op.get('schema', {})
+   struct_info = operator_schema.get('structTypeInfo', {})
+   fields = struct_info.get('fields', [])
+
+   has_delete_col = any(f.get('name') == '__incremental_deleted' for f in fields)
+
+   if has_delete_col:
+       append_only_type = "with_delete"  # 有删除
+   else:
+       append_only_type = "append_only"  # 纯增
+   ```
+
+2. **Join 算子**：
+   - **优先检查 DeltaState 模式**（新增规则）：
+     - `DeltaState-` 表示有删除（非纯增）
+     - `DeltaState+` 表示纯增
+   - **如果没有 DeltaState 模式**，按以下逻辑：
+     - **情况1**：只有一路是 delta，且 join type 是 `inner/anti/left_semi`
+       - 继承该 delta 输入的 append-only 类型
+     - **情况2**：所有输入都是 delta，且 join type 是 `inner/left_semi/anti`
+       - **必须检查 Rule hint**：join 上必须有 Rule pattern（如 `Rule:IncrementalJoinWithoutCondenseRule`）
+       - 所有 delta 都是纯增且有 Rule hint 时，join 的 delta 才是纯增
+     - **其他情况**：默认为有删除
+
+   ```python
+   # 新增：优先检查 DeltaState 模式
+   op_str = json.dumps(op)
+   if 'DeltaState-' in op_str:
+       append_only_type = "with_delete"  # 有删除
+   elif 'DeltaState+' in op_str:
+       append_only_type = "append_only"  # 纯增
+   else:
+       # 原有逻辑
+       join_type = get_join_type(op)  # 从 hashJoin.join.type 路径提取
+       delta_inputs = [inp for inp in inputs if inp.data_type == 'delta']
+
+       if len(delta_inputs) == 1 and join_type in ['inner', 'anti', 'left_semi']:
+           # 继承该 delta 输入的 append-only 类型
+           append_only_type = delta_inputs[0].append_only_type
+       elif len(delta_inputs) == len(inputs) and join_type in ['inner', 'left_semi', 'anti']:
+           # 多 delta join：必须检查 Rule hint
+           if all(inp.append_only_type == 'append_only' for inp in delta_inputs) and has_rule_hint(op):
+               append_only_type = "append_only"
+           else:
+               append_only_type = "with_delete"
+       else:
+           append_only_type = "with_delete"
+   
+   def get_join_type(op):
+       """从 hashJoin.join.type 路径提取 join type"""
+       if 'hashJoin' in op and 'join' in op['hashJoin']:
+           return op['hashJoin']['join'].get('type', 'unknown').lower()
+       # 类似处理 nestedLoopJoin, broadcastHashJoin
+       return 'unknown'
+   
+   def has_rule_hint(op):
+       """检查是否有 Rule hint pattern"""
+       op_str = json.dumps(op)
+       return 'Rule:' in op_str
+   ```
+
+3. **Aggregate/Window 算子**：
+   - **优先检查 DeltaState 模式**（新增规则）：
+     - `DeltaState-` 表示有删除（非纯增）
+     - `DeltaState+` 表示纯增
+   - **如果没有 DeltaState 模式**：继承输入的 delta 是否纯增
+
+   ```python
+   # 新增：检查 DeltaState 模式
+   op_str = json.dumps(op)
+   if 'DeltaState-' in op_str:
+       append_only_type = "with_delete"  # 有删除
+   elif 'DeltaState+' in op_str:
+       append_only_type = "append_only"  # 纯增
+   else:
+       # 继承输入的 append-only 类型
+       # 只要有一路不是纯增，则该算子 delta 都不是纯增
+       if any(inp.append_only_type == 'with_delete' for inp in inputs):
+           append_only_type = "with_delete"
+       else:
+           append_only_type = "append_only"
+   ```
+
+   **DeltaState 模式示例**：
+   ```
+   HINT=delta,DeltaState-:[1,1896] - [1,6393]_IncrementalWindowSetDeltaRule#cz::optimizer::Window#44
+   ```
+   - `DeltaState-` 中的 `-` 表示有删除
+   - `DeltaState+` 中的 `+` 表示是纯增
+   - 所有 aggregate/join/window 都有类似 pattern
+
+4. **其他算子**：
+   - 把所有输入的 delta 一起看
+   - 只要有一路不是纯增，则该算子 delta 都不是纯增
+
+   ```python
+   # 过滤出 delta 输入
+   delta_inputs = [inp for inp in inputs if inp.data_type == 'delta']
+
+   # 只要有一路不是纯增，则不是纯增
+   if any(inp.append_only_type == 'with_delete' for inp in delta_inputs):
+       append_only_type = "with_delete"
+   else:
+       append_only_type = "append_only"
+   ```
+
+**应用场景**：
+
+- **4.2.3 Window 优化**：检查 window 输入是否是 append-only
+- **4.2.6 Aggregate 复用**：MIN/MAX 在 append-only 情况下应该使用之前的结果
+
+**⚠️ 新增规则总结**：
+
+**DeltaState 模式优先级最高**：
+- 对于 Join/Aggregate/Window 算子，优先检查 `DeltaState-` 或 `DeltaState+` 模式
+- 如果存在 DeltaState 模式，直接根据 `+/-` 符号判断是否纯增
+- 只有在没有 DeltaState 模式时，才使用原有的继承逻辑
+
+**模式示例**：
+```
+HINT=delta,DeltaState-:[1,1896] - [1,6393]_IncrementalWindowSetDeltaRule#cz::optimizer::Window#44
+HINT=delta,DeltaState+:[1,1896] - [1,6393]_IncrementalAggregateRule#cz::optimizer::Aggregate#123
+```
+
+**判断优先级**：
+1. **DeltaState 模式** → 直接判断（最高优先级）
+2. **原有逻辑** → 继承输入或检查 Rule hint（备用逻辑）

+# 优化原则和参数推荐指南
+
+本文档定义了性能优化分析中的参数推荐原则。
+
+**适用范围**：
+- 所有增量优化规则
+- 所有性能分析建议
+
+**相关文档**：
+- [Stage/Operator 优化](./stage-operator-optimization.md) - Stage 和 Operator 级别优化
+- [增量算法分析](./incremental-algorithm-analysis.md) - 增量算法识别和分析
+- [状态表优化](./state-table-optimization.md) - 状态表相关优化规则
+
+---
+
+## 参数推荐原则
+
+### ❌ 禁止行为
+
+1. **不要给没有依据的参数**
+2. **不要凭空给 flag**
+3. **不要推荐已存在且正确的参数**
+
+### ✅ 必须做到
+
+1. **仅在发现实际问题时才建议参数**
+2. **每个建议必须有明确的触发条件**
+3. **每个建议必须引用实际数据作为证据**
+4. **必须检查 settings 避免重复建议**
+
+### 📋 其他可能有用的参数
+
+对于那些**可能**有用但没有明确问题证据的参数：
+- 单独列出
+- **不要给强烈建议**
+- 让用户自行决定是否重跑
+
+### 📝 脚本生成原则
+
+- 优化规则脚本中尽量使用 `logger` 来打印日志，除一些整体步骤等信息可以使用 `print`
+- 示例：
+  ```python
+  # ✅ 规则内部分析日志用 logger
+  logger.debug(f"Stage {stage_id}: 分析倾斜情况...")
+  logger.info(f"发现问题: {description}")
+  
+  # ✅ 整体流程步骤可以用 print
+  print("步骤1: 解析输入文件")
+  ```

+```
+使用create-skill工具来创建skill，同时md尽量使用中文，文件名用英文，内容尽量用中文
+
+1. 输入了几个文件，对应的是job的plan和执行统计信息，plan是指包括执行计划、dag图等，执行统计信息是runtime跑的数据量和执行时间等；
+    如果job_profile.json为空，则相关处理job_profile.json逻辑可以略过；好比，增量状态表部分，有些逻辑主要是分析了plan.json，则应该可以给出这部分结果；
+2. 输入的文件分别是job_profile.json是执行器跑的时间和数据量统计；plan.json则是执行计划，包括dag图，两者需要结合起来，如hashjoin，从job_profile.json不知道是hash-hash shuffle hash join还是broadcast hash join等；
+3. 初始化一些主要信息，
+    3.1 分类sql。从plan.json找出cz.sql.text是不是 refresh命令，如果是，则按照分类sql来找出需要优化的点；
+    3.2 版本信息；plan.json可以获取版本(build_info里记录了，如，GitBranch:release-v1.2等信息），但版本不要暴露给结论，告诉你版本主要是后续会许升级到不同版本可能需要不同flag；
+    3.3 vc信息；同时可以查看cz.inner.is.ap.vc是不是ap，如果为0，则不是ap模式，表示是gp模式，如果为1，则为ap模式，后续优化也会区分是ap还是GP；对于ap，则拿cz.analyze.instance.executor.count参数表示vc等core数；如果是gp，则拿cz.sql.gp.vc.capability的参数，同时除以100得到数值表示vc的core数;
+    3.4 setting，plan.json记录了所有已经设置的flag，提示你如果已经有了，就不要再给建议了（不要在结论中提这些flag）
+    3.5 执行计划，plan.json中的dml->stages里记录了所有dag执行的stage信息，同时对应着job_profile.json那些stage；
+    3.6 统计所有operator耗时，以及在其stage的占比和整个sql占比，目的是为了后续做一些优化时，可以反复利用这些统计结果
+    3.7 根据上面初始化信息得到的场景来选择后续使用的分析和优化策略
+        增量计算job的分析和优化
+        compaction job分析
+        gpjob分析
+        apjob分析
+        等其他各种分类
+    3.8 整体每个阶段耗时分析；job_profile.json记录了每个阶段的开始时间，这样两个阶段之间就是这个阶段的耗时
+4. 增量计算refresh sql优化，即增量相关的sql优化
+  增量job任务优化分两大块，一种是从运行的stage/operator算子级别优化，一种是优化状态表
+  4.1 增量stage/operator级别优化
+    4.1.1 增量refresh还是全量refresh;可以从plan.json找到refresh的table名字，如果plan中refresh table的tablesink算子是OVERWRITE，但是不是写delta tablesink(plan.json中是找到tablesink算子，然后在table/path对应的字段找，可能是3元组，也可能是4元组，4元组，则一般最后一个是__delta__，表示写入delta文件的tablesink)，如果不是写delta tablesink则表示是全量(即overwrite sink的不是delta，且overwrite=true则表示是全量），否则是增量，同时忽略一些中间表，目前是通过名字带有__incr__这种pattern，表示的是中间状态，则这些暂时可以忽略，即不要找错了refresh的table名字；
+    4.1.2 单dop aggregate stage优化；如果stage是dop=1（可以从job_profile.json里找），如果stage里包含了Hashaggregate的Final/Complete状态（可以从相应plan.json找），并且是计算类似MULTI_RANGE_COLLECT,_DF_BF_COLLECT这些聚集函数，耗时较长，则可以给出走3阶段建议，需要设置set cz.optimizer.incremental.df.three.phase.agg.enable=true;即这个stage优化建议是设置该参数,如果已经配置了该参数，可能aggregete使用了one pass，即complete phase，则可以加上 set cz.optimizer.enable.one.pass.agg=false;来优化，同时如果还是耗时较长，没有生成3阶段，看下aggregate上的bits是多少，如果大于等于536870912，小于1073741824，则可以设置 set cz.optimizer.df.three.phase.agg.bf.width.threshold=某个值，即bits大小，因为默认该阙值是1073741824(1.3版本以及1.3以下版本是这个，1.3以上默认值是536870912)，小于这个则不会生成3阶段，如果bits小于536870912，建议不要修改该参数；如果有类似final stage还是很慢，麻烦看下它上游stage，是不是没有走aggregate的P2，这样也会导致final agg很慢，如果是同样给出再看看没有开启3阶段，以及bits是不是比1073741824小，则需要调整；请同时看是否开启3阶段以及bits大小是否符合，否则仅仅开启3阶段还是无法达到预期；额外条件，如耗时，耗时比较多
+        即优化条件：
+        aggregate是Final或Complete状态，且上游不是P2状态，即没有开始3阶段aggregate
+        （耗时超过20s以上且占总体10%以上）或者 耗时超过30s
+        stage输入数据（一般是shuffle read算子）超过20M
+        dop=1
+        agg有指定agg function
+        如果未打开，则可以加上3阶段优化flag set cz.optimizer.incremental.df.three.phase.agg.enable=true;,如果已经有cz.optimizer.df.enable.three.phase.agg=true，则也不需要单独设置打开3阶段flag功能；
+        但，如果不是3阶段需要检查bits是否满足，不满足需要额外加width threshold大小
+    
+        如果看到有aggregate是有MULTI_RANGE_COLLECT，但是没有_DF_BF_COLLECT或者_DF_SET_BF_COLLECT，则高优先级提示，说明bf(bloom filter)未收集对于裁剪会不佳；如果是1.3版本，则添加这些set cz.optimizer.incremental.df.three.phase.agg.enable=true;
+                set cz.optimizer.df.three.phase.agg.bf.width.threshold=536870912;
+                set cz.optimizer.df.bf.width.max=2147483648;
+                set cz.optimizer.df.bf.width.min=1073741824;
+                set cz.optimizer.incremental.enforce.creating.bf=true;
+        但如果已经存在flag，则不要加；
+    4.1.2 hash join优化；如果stage且耗时较长，如果stage里有join，且join占比比较多，可以看看是不是join的算法是hash-hash算法还是broadcast算法，统计信息可以从job_profile.json找，使用了什么算法，可以从plan.json找，一般来说，如果是broadcast，且shuffle量超大，则可以考虑禁止broadcast hash join，则给出优化建议是set cz.optimizer.enable.broadcast.hash.join=false;
+    4.1.3 stage包含tablesink算子优化；我们stage的dop是通过累加得到，如果stage包含了tablesink算子(且不是partial sink,判断逻辑是sink算子的flags字段, flags & 0x20!=0表示partial sink；同时也不是DELTA sink，即path最后一个元素是__delta__的4元组)，但是dop与上游不太一致，如果该stage耗时比较长，dop又与上游dop差异较大，且stage耗时较长(占总体超过10%)则可能是由于会根据table的目标文件大小自动调整了dop，则给出set cz.sql.enable.dag.auto.adaptive.split.size=false;（要求是已经设置该flag为true才需要），该参数目的是不根据table的目标文件大小来自动调整dop;如果在这种场景下，stage里没有tablesink算子不要加该参数，即dop小并不是由于需要根据table目标文件大小来调整；同时建议看看每个stage的taskCount，如果其上游dop和自己相差不大，建议不要设置cz.sql.enable.dag.auto.adaptive.split.size，即下游stage一般不会超过上游dop,在不超过情况下不需要设置；
+        即，优化条件
+        stage包含tablesink算子（且不是partial sink，判断逻辑：flags & 0x20 != 0；也不是DELTA sink，即path最后元素是__delta__）
+        stage耗时占总体10%以上
+        dop与上游差异大
+        dop如果与上游dop差不多（即计算依赖stage的
+        task count)，则不需要额外设置cz.sql.enable.dag.auto.adaptive.split.size=false，即不需要根据此情况调整dop
+        stage的dop大于上游stage的dop，则也不需要调整该参数，即下游dop都已经大于了上游，为啥还要调
+    4.1.4 最大dop优化提示；我们dag这边限制了map的最大dop=4096，reduce最大dop=2048，所以碰到类似这种dop可以认为不是dop有问题，除非你有足够信服的理由，或者主动调整过这些dop，如cz.optimizer.mapper.stage.max.dop,cz.optimizer.reducer.stage.max.dop这些对应的flag;
+    4.1.5 spillingBytes优化；关于spillingBytes分析，请按照算子级别来分析支持，一般有几种情况，一种是stage级别的总spill大小，还有一种是operator级别，可以相关spill stats看到有opId的，所以请根据这些级别来分析；如果是shuffle write的spill可能可以忽略；
+    4.1.6 倾斜优化提示；
+        1）profile里看stage的taskSummary每个task情况；如果发现只有少于5%的task有数据，则可能认为倾斜；同时需要满足stage耗时占总体超过15%才认为值得优化（避免对耗时很短的stage进行优化）；如果stage有scan算子，则看看尝试提示调整split size；set cz.mapper.file.split.size=xxx;默认是256M(268435456)，可以调小到64M等；如果有shuffleread，则可以提示关注是否有倾斜数据;
+    4.1.7 从job_profile.json中taskSummary拿到每个stage的dop(可以参考4.1.3对应的代码),分析每个task跑的时间，假设给足资源(即vc core数，见3.3)情况下，整体stage需要跑多久（如，最大task时间，以及总体task数在现有资源下跑多少轮可以结束），然后再对比实际跑了多久，如果实际跑的时间是预计资源足情况的2倍以上，则给出提示；
+    4.1.8 请你给出其他我未发现的问题，这里我发现你完全没理解，即不给任何分析，这里可以对所有stage看看时间耗时，对于那些比较慢的，可以主动分析为什么慢，如operator慢？还是其他等原因，希望你可以更smark点
+  4.2 状态表优化
+    4.2.0 如果给的prompt中没有提到使用状态优化，则不需要来使用下面优化原则来优化
+    重要：关于状态表这些优化必须是对应算子的对应增量算法，如aggregate则必须是增量算法产生的，join/window等都类似；可以根据4.2.1.2来判断；即只有包含增量hint的算子才需要进行状态表优化分析，没有增量hint的算子应该跳过；
+    4.2.1 看看当前的job是否是增量刷新的job，即4.1.1提到的如何判断是增量还是全量，以及增量计算的整体plan分析
+        4.2.1.1 识别所有operator(算子)是delta还是snapshot；如果是增量plan，由于是增量计算的plan，可以收集哪些表是是增量数据，哪些是读snapshot其中，对于tablescan算子，incrementalTableProperty有from/to分别记录了版本是从哪个版本到哪个版本，如果 from=28800，to=57000，则表示delta，如果from=-9223372036854775808，且to=28800表示表读数据的上个状态，或from=-9223372036854775808,to=57600，表示是当前状态，即(from=-9223372036854775808,to=28800，即上个状态或者说上个snapshot) + (from=28800, to=57600,即delta数据) = (-9223372036854775808=-9223372036854775808,to=57600，当前状态或者当前snapshot)
+        ，即 只有在from=28800且to=57600情况下表示tablescan的数据是delta,如
+        incrementalTableProperty": {
+            "from": "28800",
+            "to": "57600",
+            "fromMetaVersion": "0",
+            "toMetaVersion": "0"
+        }，该json例子表示是delta，其他都是snapshot，snapshot有一个明显特征是from=-9223372036854775808
+        注意：只有包含incrementalTableProperty的tablescan才需要分析，没有该属性的tablescan（如delta元数据扫描）应该跳过；
+        同时，需要区分业务数据扫描和元数据扫描：如果schema包含file_path, pos, commit_ts, operation, field_id, value等字段，则是delta元数据扫描，不是业务数据，应该跳过分析；
+        这样就方便分析增量算法，对于join/aggregate/window增量算法你自己根据相关知识找到算法逻辑，从而推导出增量plan的形态,如delta(join)算法=delta(Left) join delta(right)，即计算出left和right的delta数据就可以得到join的delta，也可以认为是重算rule，类似对于aggregate/window也是类似，下面的一些分析请区分出哪个是真正的join/aggregate/window的增量算子再添加状态，有些aggregate是算法的一部分，而不是对应原始sql里的aggregate，请注意区分，同时window/join也是类似
+        一般一元算子，如果输入是delta，则自己输出也是delta，输入是snapshot，则自己输出也是snapshot;
+        如果是join，只有left和right都是snapshot，join结果才是snapshot；
+        对于union多元算子，如果输入都是snapshot，则union输出也是snapshot，如果全部输入是delta，则union输出也是delta，如果部分delta，部分snapshot，应该也是snapshot，但这种plan一般不太会出现，也可以列出来，看看是不是你脚本处理问题；
+        其他多元算子，可以展示出来，可能遗漏了，一般也可以按照union规则处理；
+
+        ⚠️ 重要补充：增量算法Hint优先规则
+        - 如果算子有增量算法hint（如IncrementalJoinRule, IncrementalAggregateRule等），该算子应该被标记为delta
+        - 这是因为增量算法是用来处理增量数据的，即使输入是snapshot，增量算法也会输出delta
+        - 增量算法的语义：可以接受SNAPSHOT输入并产生DELTA输出（通过比较两个snapshot计算差异）
+        - 检查方法：在算子的JSON中查找"Incremental"或"DeltaState"关键字
+        - 优先级：增量hint检查应该在基于输入的传播规则之前执行
+        - 实际案例：HashJoin有IncrementalJoinWithoutCondenseRule hint，即使一个输入是SNAPSHOT，另一个是DELTA，该HashJoin仍应标记为DELTA
+
+        同时在plan.json里找到所有operator对应的Id，注意这里的ID不是代码中那些index下标，即使用 plan.json 中的实际 operator ID，而不是数组索引；注意这里一个算子可能有多个下游
+        注：这里依赖关系不要和stage挂勾，代码如果有请修正；
+        4.2.1.2 识别不同算子的增量算法；4.2.1.1已经知道了所有增量算子的依赖关系，你就能自动识别增量算法，可以把所有算子operator的delta/snapshot依赖关系整理串联起来；可以得到所有算子是计算delta还是snapshot，同时有些算子会有hint记录类似Rule:xxx这种pattern，如，Rule:IncrementalLinearFunctionAggregateRule，这个增量rule表示是计算aggregate的一种增量算法（即，rule名字包含了Aggregate，其他规则类似），如果这种hint不是在Aggregate(如，在join上)上，则说明这些算子是为了计算Aggregate增量算法的一部分；其他类似join/window增量算法也可以类似处理，有些hint计算的Rule有一些算子Id，如果一个Id出现在不同地方，说明这些整体都是来计算同一个算子的增量算法，如Rule:IncrementalJoinWithoutCondenseRule_cz::optimizer::LogicalJoin#31766417，这里的LogicalJoin#31766417表示为了计算该join算法而加的hint，这样所有相同都是为了计算同一个join，即属于Join算法的一部分；有些增量算法会打上其他hint，类似HINT=delta,DeltaState:[1,1896] - [1,6393]_IncrementalWindowSetDeltaRule#cz::optimizer::Window#293342，其中第一部分delta表示计算delta，即增量算法都是计算delta数据来优化，DeltaState表示该算子是整体增量算法的状态算子，IncrementalWindowSetDeltaRule表示是使用的算法，Window#293342则表示是对哪个算子计算了增量算法，如果没有这些类似Id，则可能是没有加上id来标识，不要误把没有加的hint当作是认为计算同一个算子；然后这样找出每次计算一个算子增量算法的边界其实可以区分出来；
+        如aggregate，如果是重算算法，则可能是根据([输入是delta] join [输入的snapshot])得到变动的aggregate输入，然后再计算aggregate就可以得到aggregate增量算法，所以这里aggregate增量算法就用到了join算子等；
+        4.2.1.3 算子增量算法对应的subplan，如包含哪些算子，算子对应的root阶段是什么；上面一步一步得到了每个算子的delta/snapshot，以及他们之间的依赖关系，这些都是可以认为是operator之间关系，忽略stage之间关系；通过上面hint以及operator之间的依赖关系，这样就可以知道这一些长串的算子对应了某个算子的增量算法，把这些进行归类，需要把一个增量算法对应的所有算子都找到，这里对应的plan.json的"id"字段表示每个算子的唯一id；
+        根据4.2.1.2找到相同增量算法的算子，对于一些没有找到id的rule hint应该往自己下游继续查找，找到第一个带有id且同类（是指是相同算子，如，都是agg/window/join等）的增量算法，这些算子联通(遍历)起来的算子一定属于该算法的subplan一部分（即，类似有N个点组成的一个图，点中间的所有算子肯定属于该增量算法），然后按照下面规则遍历“这些一定属于该算法的算子”的上下游算子来剩下的其他算子属于该增量算法，直到边界算子结束;
+        这里的算子增量算法对应的subplan不是让你把rule相同的合在一起，rule相同的算子肯定来源于同一个算子对应的增量算法，而是让你把某一个增量算法涉及到的所有算子都包含起来，这些算子不一定有Rule这些hint，即他们是一个执行的subplan，而不是这些零散的hint operator组成，即subplan 应该包含整个执行路径的所有算子，而不仅仅是有 Rule hint 的算子;
+
+        关于DeletePlan的处理：
+        - DeletePlan相关hint用于表示删数据的plan，不属于任何增量算法
+        - 在解析Rule hints时，应该忽略（过滤）所有DeletePlan相关hint，不作为增量算法的起点
+        - 在遍历查找subplan时，如果遇到DeletePlan相关算子，必须作为边界条件终止遍历
+        - 为什么必须终止而不是跳过：因为plan是执行路径，如果跳过DeletePlan继续查找，找到的subplan会缺少中间算子（不完整），这样的subplan不能算是增量算法的一部分
+
+        每个增量算法包含哪些operators，需要设置边界条件：
+        (1)碰到不是相同hint要终止，避免跨越算法边界，需要添加到subplan里；
+        (2)aggregate增量算法在查找自己涉及哪些算子时，上游碰到了final/complete状态也要终止，即表示在自己算delta，那已经结束了，需要添加到subplan里；
+        (3)碰到deleteplan相关算子必须终止，因为它不属于任何增量算法，且plan是执行路径不能跳过，不需要添加到subplan里；
+        (4)对于snapshot的算子，必须终止，因为snapshot表示snapshot状态，用来构造增量算法的输入节点，不需要把计算snapshot的整个过程都添加到增量算法的operators中，但snapshot算子本身属于增量算法一部分，需要添加到subplan里；
+        (5)如果是calc有hint，且hint包含了DeltaState和Incremental这些也需要终止，避免跨越算法边界；如，类似DeltaState:[1,14] - [1,43]_IncrementalJoinWithoutCondenseRule#cz::optimizer::LogicalJoin#973；注意：这种calc算子虽然要终止遍历，但在bottom-up遍历时应该将该算子包含到对应增量算法的算子中，即包含该算子但不继续向上游或下游遍历，需要添加到subplan里；
+        (6)增量算法查找算子时，如果碰到aggregate，且aggregate的聚集函数包括MULTI_RANGE_COLLECT或者_DF_BF_COLLECT，则终止，不需要添加到subplan里，因为这个是一个df的aggregate，仅仅是优化的一个plan，不需要添加；
+
+        验证规则（这些是规则不是告警，如果不满足，说明脚本有问题，请修改）：
+        - 同一个operator不应该属于两个不同的增量算法，或者只有增量算法的对应root节点或者tablescan才能横跨多个增量算法
+        - 如果一个算子又不是增量算法的root节点，又属于多个增量算法，则应该有问题
+        - 由于计算算子的delta/snapshot是从上游operator到下游operator经过propogate，所以如果某个operator属于了上游的增量算法，就不应该属于下游
+        - 从找到的root节点开始top-down遍历所有算子，在碰到了非边界算子前是不是有其他增量算法的算子，如果有，说明脚本有问题；同时保证自己的所有operator一定能遍历到，如果还有没遍历的算子，说明脚本有问题，请修改；
+            4.2.1.3.1 Aggregate算子的增量算法，如果发现有hint，则可能需要往依赖的下游算子继续查找，找到是Final/Complete状态的Aggregate算子才算结束，甚至有些Aggregate增量算法可能是由多路union得到，则这样还需要把union下游算子找到Aggregate的Final/Complete算子，即union 两边可能包含了相同的hint，则需要这些输入相交合并后继续查找得到他们的subplan，这些执行路径的算子也属于Aggregate；其他算子的增量算法应该也需要这样查找，即对于相同hint（表示同一个算子对应的增量算法，注意有些没有Id来唯一标识，这个时候别搞错了）如果不是同一个分支执行路径算子，需要合并起来得到；
+        每个增量算法得到了自己所有算子后，把所有tablescan算子找出来，如果所有的delta类型的scan全部是appendonly的tablescan，则显示出来，并标注；如果不全部是，也请显示每个tablescan是不是appendonly；appendonly信息在4.2.1.5里已经得到，从这里拿；
+        4.2.1.4 展示增量算法以及显示查看增量算法的状态信息/状态图等；把整体增量算法是计算哪些算子的依赖关系画出来，好比，这一堆算子是计算aggregate，这一堆算子是计算join等等，同时画出他们的依赖关系，这样就知道先计算aggregate再计算join，还是先计算join再计算aggregate等; 同时可以让prompt方式可以查看到增量算法图或者状态图，如哪些算子组成了aggregate算法，哪些算子组成了join等等(即脚本里应该可以直接分析查看，如传递参数等)；
+        4.2.1.5 算子delta是appendonly(纯增delta)还是有删除的delta;在4.2.1.1已经计算了算子是delta还是snapshot，现在需要区分delta是纯增还是有减（有删除的行），因为在纯增场景对于aggregate/window可以用一些更优的算法；
+        scan如果是delta，则看是不是输出__incremental_deleted列（注意是过去式deleted，不是delete）。检查方法：从算子的实际输出列（operator.schema.structTypeInfo.fields）查找是否输出该列，而不是从表定义的完整schema（tableSchema）查找。如果输出__incremental_deleted列，则表示delta不是纯增；如果没有输出，则表示delta是纯增；
+        join算子，则看所有的input是不是delta，如果只有一路是delta，且join type是inner/anti/left semi，则继承该输入的delta是不是纯增；如果所有输入input都是delta，所有delta都是纯增，且join上有类似HINT=Rule:这种pattern，且join type是inner/left_semi/anti时，则join的delta也是纯增，否则认为是非纯增；
+        aggregate/window算子继承输入的delta是否纯增。增量算法标记（4.2.1.2）只表示使用了增量算法，不影响append-only判断；append-only完全取决于输入数据（TableScan是否输出__incremental_deleted列）；
+        其他算子都是把所有输入的delta一起看，只要有一路不是纯增，则表示该算子delta都不是纯增的；
+        还有一些规则，如，window，类似这种HINT=delta,DeltaState-:[1,1896] - [1,6393]_IncrementalWindowSetDeltaRule#cz::optimizer::Window#44的pattern，DeltaState-中的-表示有删除，DeltaState+中的+表示是纯增，所有aggregate/join都有类似pattern；
+    4.2.2 提示非增量原因；如果job非增量刷新，且版本小于等于1.3，则请设置这些flag（
+        set cz.optimizer.print.non.incremental.reason=true;
+        set cz.optimizer.print.non.incremental.reason.msg.max.length=100000;
+        set cz.optimizer.incremental.force.incremental=true;
+        ），加上这些flag后，会提醒用户没有增量的原因；如果是1.4以及以上版本，则如果加上cz.optimizer.incremental.try.incremental.refresh.enabled=true,会提示为什么没有走增量；
+    下面优化策略都是基于plan是增量plan而需要查看的，所有算子之间的依赖关系理论上4.2.1已经构建好了，下面规则应该复用这些已经构建好的依赖关系；
+    同时关于状态表这些优化必须是对应算子的对应增量算法，如aggregate则必须是增量算法产生的，join/window等都类似；可以根据4.2.1.2来判断；
+    4.2.3 window算子在输入delta是appendonly(即纯增的增量，没有删除delta)优化；
+        window算子的父节点是calc，且存在 row number=1的pattern（表示的是window的rownumber函数输出后，在calc里面有这个列=1的pattern），请看看window的输入是否是append-only的delta（即，4.2.1.5）。注意：判断window输入是否append-only应该使用4.2.1.5中IncrementalAlgorithmAnalyzer分析的全局结果（operator_append_only_types），该结果包含了跨stage的所有算子的append-only信息，而不是在当前stage内搜索TableScan（因为TableScan可能在不同stage）。如果是append-only且rn=1的pattern，但是window没有使用IncrementalLinearTopKWindowRule增量算法（注意：支持V1和V2版本，即IncrementalLinearTopKWindowRule或IncrementalLinearTopKWindowRuleV2），则请设置以下flag继续尝试cz.optimizer.incremental.window.sd.to.sd.rule.enable=false; 如果是append-only的delta输入，则一直检查到tablescan，查看tablescan的table属性是否有property：incr.append.only.table=true 或者 job是否flag具备 cz.optimizer.incremental.append.only.tables='xxx'，如果没有这些flag或者properties请提醒用户需要在该表添加上incr.append.only.table=true属性（注意：incr.append.only.table属性仅用于提醒用户设置，不影响append-only的判断逻辑）；
+        rn=1 pattern如何查找可以类似参考{"function":{"from":"","name":"EQ","builtIn":true,"arguments":[{"reference":{"id":"0","local":false,"from":"","name":"","refType":"LOGICAL_FIELD"},"typeReference":1},{"constant":{"bigint":"1"},"typeReference":1}],"properties":{"properties":[]},"execDesc":"EQ(i64,i64)->b","functionProperties":{"properties":[]}},"pt":{"start":{"line":1,"col":7356,"pos":7355},"end":{"line":1,"col":7364,"pos":7363}},"typeReference":13}
+        这里的EQ表示等于(=)，constant有个值bigint:1，表示是1，所以对应的其实就是xx=1
+    4.2.4 基于我教给你的4.2.3的方法，看看当前query中是否还包含append-only的scan，如果包含，根据你的经验预判一下当前是否使用的算法并非最优的
+        核心思想：如果系统中仍然存在对append-only数据的扫描，说明可能没有充分利用append-only特性进行优化。理想情况下，append-only数据应该通过增量算法处理，而不是重复扫描。
+        检查逻辑：
+        1. 根据4.2.1.1规则，只分析有incrementalTableProperty且from != -9223372036854775808的delta业务数据扫描
+        2. 排除delta元数据扫描（schema包含file_path, pos, commit_ts, operation, field_id, value等字段）
+        3. 排除中间状态表（表名包含__incr__, __state__, __temp__等pattern）
+        4. 对于真正的append-only业务数据扫描，分析为什么还在扫描而不是使用增量算法：
+           - 检查是否可以使用状态表避免重复扫描
+           - 检查是否已使用增量算法（通过hint检测）
+           - 综合评估append-only数据特性是否被充分利用
+    4.2.5 是否有创建中间状态表；即看整个job的所有stage中tablesink是不是有表名包含__incr__；如果不包含，可以设置cz.optimizer.incremental.enable.state.table=true;来开启中间状态优化。但是在开启之前，我希望你根据经验判断一下当前是否值得存储中间状态，你可以从以下几个方面进行判断：1.是否需要状态（可以参考流计算的带状态计算的定义），但必须是增量算法产生的算子（根据4.2.1.2的hint判断），2.状态表是否过大（请根据当前看到的每一步的stats信息和输入表的增量数据大小进行合理判断）；
+        对于有有状态算子，需要区分增量算法是不是对应的增量算法，如，join算子对应的rule是join，aggregate类似，除非是第一次出现hint的operator，否则应该都有对应关系，不要错误把一些增量算法的中间算子当作自己本身
+        注意：状态表检查应该是job级别的，不仅仅检查当前stage，需要检查整个job的所有stage是否已包含中间状态表，避免误判；
+        基于算子是增量算法来创建中间状态表优化的逻辑，在未提示情况下默认不开启；
+        找算子是snapshot（即类似全量计算这个subplan）占比比较高的(如，15%以上等)，一般这种需要创建中间表状态表；这里的operator是snapshot是指整个路径上所有的snapshot的耗时在整体的占比，因为如果中间表物化后就可以减少这部分计算；同时打印出该snapshot的“骨架”，即把重要算子打印出来，如aggregate/join/window/tablescan，aggregate打印出聚集函数，window类似，这样方便从原始sql找到对应的sql，这样join等就知道是从哪个tablescan开始到哪里结束需要创建中间表；
+    4.2.6 aggregate linear rule优化；该aggregate必须设置上了hint包含类似4.2.1.2的一些状态hint，如果不包含，说明该aggregate算子不是原始sql中的aggregate，而是其他优化器rule等自己生成的，这些不需要检查；然后看看当前任务中aggregate的计算是否利用上了之前的计算结果（对于SUM，COUNT希望无论如何都尽量使用之前的结果，对于MIN，MAX希望在append-only的情况下尽量使用之前的结果），如果发现没用上，请根据4.2.5我教会你的方法看看是否存在状态，如果状态存在，请根据4.2.1.5教会你的方法看看是否有append-only的输入，如果是append-only但是缺少系统hint的，请补充上hint
+    4.2.7 占比时间长calc可以存状态，如，calc占整体stage超过30%，同时整个stage在整体耗时占比15%以上,如果发现这类calc，可以看calc是不是有比较占比高的function计算，特别是udf(即用户自定义function)则可以通过set cz.optimizer.incremental.create.rule.based.table.on.heavy.calc=true;进行优化
+        额外条件：
+        - calc必须是snapshot状态（不是delta），如何获取见4.2.1.1规则，从operator_data_types中获取
+        - 输出信息应包含：calc耗时、calc占stage比例、stage耗时、stage占整体比例，类似4.1.6倾斜规则的详细输出
+    总体所有满足这些优化pattern的，请可以显示出来，提供查看
+
+5. compaction优化，TODO
+6. gp job任务优化，TODO
+7. ap job任务优化，TODO
+8. job报错分析
+    8.0 统一从job_profile.json的message里收集所有错误信息，可能会有重复报错信息，记得精炼错误信息，以便提供下面错误分析优化以及给出建议；且job_profile.json中有"hint"记录了设置过哪些flag，如果下面建议提示设置什么flag，请检查是否存在，如果不存在才提示加flag；
+    8.1 提交冲突报错；从job_profile.json中找message里有如“this job has conflicts with another concurrent job which updates”，解决方法提示只要重跑整个job；
+    8.2 优化器报错；
+        8.2.1 提示生成playback信息；message里如果包含类似“Optimizer internal error”这种错误，则提示设置cz.sql.playback.scratch=true，重新跑报错job，这样会有playback信息，提供优化器定位问题；
+        如果已经设置了cz.sql.playback.scratch=true，则不需要提示添加flag，而是提示已经有了信息可以找技术支持；
+        8.2.2 TODO（针对不同错误信息可能有不同策略，暂时未实现）
+9. 不要给没有提示的参数，即有些你给的flag是凭空说的;只在发现实际问题时才建议参数；其他的请单独列出，但是不要给什么强烈建议这种重跑，交给用户自己决定；
+10. 可以将脚本按照不同sql分类来进行拆开，后续便于管理，即要考虑后续skill如何迭代；构建脚本尽量以不同场景来构建，方便扩展，如增量是一类，compaciton是一类等等;
+   脚本命名不要和数字结合，容易导致prompt变了，但脚本数字和prompt对应不上问题
+11. 脚本和md里不要出现v3，规则3这种带有版本或者数字第几章的东西，后续无法维护
+12. 脚本生成原则，优化规则里尽量用logger来打印，除一些整体的步骤等打印可以使用print

+## 当前问题
+- 单一脚本 30KB+，所有逻辑混在一起
+- REFRESH SQL、Regular SQL、AP/GP 模式代码耦合
+- 后续新增规则（如 4.2 状态表优化）难以扩展
+- 规则迭代时需要修改大量代码

+## 新架构设计
+
+### 关键理解
+1. **第 3 章是完整的增量计算分析**，包含两个部分：
+   - 3.0-3.6: Stage/Operator 级别优化（对应原来的 4.1）
+   - （未来）状态表级别优化（对应原来的 4.2）

+
+### 2. 分析器组合规则
+每个分析器组合对应类型的规则：
+```python
+# analyzers/incremental_analyzer.py
+class IncrementalAnalyzer(BaseAnalyzer):
+    """增量计算分析器 (第3章 REFRESH SQL)"""
+    
+    def __init__(self):

+        from rules.incremental.stage_optimization import (
+            RefreshTypeDetection,
+            SingleDopAggregate,
+            HashJoinOptimization,
+            TableSinkDop,
+            MaxDopCheck,
+            SpillingAnalysis,
+            ActiveProblemFinding
+        )
+        
+        self.stage_rules = [
+            RefreshTypeDetection(),    # 3.0 增量/全量判断

+    
+    def analyze(self, aligned_data):
+        # 先执行 Stage 优化分析
+        for rule in self.stage_rules:
+            if rule.check(aligned_data, self.context):
+                result = rule.analyze(aligned_data, self.context)
+                self.add_finding(result)

+                    self.add_finding(result)
+```
+
+### 3. 主脚本轻量化
+```python
+# scripts/analyze_job.py (主入口)
+from core.parser import PlanProfileParser
+from core.aligner import StageAligner
+from core.reporter import Reporter
+from analyzers import get_analyzer
+
+def main():
+    # 1. 解析输入
+    parser = PlanProfileParser(plan_file, profile_file)
+    data = parser.parse()
+    
+    # 2. 对齐 Stage/Operator
+    aligner = StageAligner(data)
+    aligned = aligner.align()
+    
+    # 3. 选择分析器
+    analyzer = get_analyzer(data.sql_type, data.vc_mode)
+    
+    # 4. 执行分析
+    findings = analyzer.analyze(aligned)
+    
+    # 5. 生成报告
+    reporter = Reporter(findings)
+    reporter.generate()
+```
+
+## 优势
+
+### 1. 易于维护
+- 每个规则独立，修改互不影响
+- 新增规则只需添加新文件，无需改动现有代码
+
+### 2. 易于测试
+```python
+# 可以单独测试每个规则
+def test_single_dop_agg():
+    from rules.incremental.stage_optimization import SingleDopAggregate
+    
+    rule = SingleDopAggregate()
+    stage_data = load_test_data("single_dop_case.json")
+    
+    # 测试触发条件
+    assert rule.check(stage_data, context) == True
+    
+    # 测试分析逻辑
+    result = rule.analyze(stage_data, context)
+    assert '三阶段聚合' in result['recommendations'][0]['reason']
+```
+
+### 3. 易于扩展
+- **新增 Stage 优化规则**: 在 `rules/incremental/stage_optimization/` 添加新文件
+- **新增状态表规则**: 在 `rules/incremental/state_table/` 添加新文件
+- **新增 AP 模式**: 创建 `analyzers/ap_analyzer.py` + `rules/ap_mode/`
+- **新增通用规则**: 在 `rules/common/` 添加
+
+**⚠️ 状态表优化规则的特殊性**：
+- 状态表优化规则**默认禁用**，需要通过 `enable_state_table_rules` 参数明确启用
+- 原因：根据 prompt 4.2.0 要求，如果用户没有提到使用状态表优化，则不需要执行这些规则
+- 使用方式：
+  ```bash
+  # 禁用状态表分析（默认）
+  cz-analyze-job plan.json job_profile.json
+
+  # 启用状态表分析
+  cz-analyze-job plan.json job_profile.json --enable-state-table
+  ```
+
+示例 - 添加新的 Stage 优化规则：
+```python
+# rules/incremental/stage_optimization/shuffle_optimization.py
+class ShuffleOptimization:
+    """新规则：Shuffle 优化"""
+    
+    name = "shuffle_optimization"
+    category = "incremental/stage_optimization"
+    
+    def check(self, stage_data, context):
+        # 检查逻辑
+        pass
+    
+    def analyze(self, stage_data, context):
+        # 分析逻辑
+        pass
+
+# 在 IncrementalAnalyzer 中注册
+self.stage_rules.append(ShuffleOptimization())
+```
+
+### 4. 便于版本管理
+```python
+# 每个规则可以有版本信息和适用条件
+class SingleDopAggregate:
+    name = "single_dop_aggregate"
+    version = "2.0"
+    min_engine_version = "1.2"
+    
+    # 规则的变更历史
+    changelog = {
+        "2.0": "增加 Bloom Filter bits 检查",
+        "1.5": "优化三阶段聚合检测逻辑",
+        "1.0": "初始版本"
+    }
+    
+    def is_applicable(self, context):
+        """判断规则是否适用于当前环境"""
+        engine_version = context.get('engine_version')
+        return engine_version >= self.min_engine_version
+```

+# Stage/Operator 级别优化指南
+
+本文档包含增量计算 REFRESH SQL 的 Stage/Operator 级别优化规则。
+
+这是增量优化的第一部分，主要从运行的 stage/operator 算子级别进行优化。
+
+**相关文档**：
+- [增量算法分析](./incremental-algorithm-analysis.md) - 增量算法识别和分析
+- [状态表优化](./state-table-optimization.md) - 状态表相关优化规则
+- [优化原则](./optimization-principles.md) - 参数推荐原则

+
+## Stage/Operator 级别优化
+
+### 4.1.1 增量 refresh vs 全量 refresh
+
+**目的**：判断 REFRESH 是增量还是全量
+
+**判断方法**：
+1. 从 `plan.json` 找到 REFRESH 的目标表
+2. 定位对应的 TableSink 算子，获取 `table.path`
+3. 判断规则（基于 `path` 和 `overwrite`）：
+   - **如果** `path` 是 4 元组且最后一个元素是 `__delta__` → **增量 REFRESH**（写入 delta 文件）
+   - **如果** `path` 是 3 元组且 `overwrite=false` → **增量 REFRESH**
+   - **其他情况**（3 元组且 `overwrite=true`）→ **全量 REFRESH**
+
+**path 格式说明**：
+- **3元组**：`[workspace, namespace, table_name]` - 例如 `['gic_prod', 'kscdm', 'dim_ks_live_daily']`
+- **4元组**：`[workspace, namespace, table_name, '__delta__']` - 例如 `['gic_prod', 'kscdm', 'dim_ks_live_daily', '__delta__']`
+
+**注意**：忽略中间表（table_name 包含 `__incr__`、`__state__`、`__temp__` 等 pattern），这些是中间状态表。
+
+**代码示例**：
+```python
+# 从 TableSink 中获取 path 和 overwrite 标志
+table_sink = stage['operators'][i]['tableSink']
+path = table_sink['table']['path']  # 列表格式
+overwrite = table_sink.get('overwrite', True)
+
+# 判断逻辑
+if len(path) == 4 and path[-1] == '__delta__':
+    refresh_type = "增量"  # 写入 delta 文件
+elif len(path) == 3 and not overwrite:
+    refresh_type = "增量"  # overwrite=false
+else:
+    refresh_type = "全量"  # 3元组且 overwrite=true
+
+# 提取表名（在 path[2]）
+table_name = path[2]
+```
+
+---
+
+### 4.1.2 单 DOP Aggregate Stage 优化
+
+**触发条件**（必须**全部**满足）：
+1. Stage 的 `dop = 1`
+2. Stage 耗时满足以下**任一**条件：
+   - **(耗时 > 20秒 且 占总耗时 > 10%)** 或者
+   - **耗时 > 30秒**
+3. Stage 输入数据（一般是 shuffle read 算子）**> 20MB**
+4. Stage 包含 **HashAggregate** 算子
+5. 聚合函数包含昂贵函数：`MULTI_RANGE_COLLECT`, `_DF_BF_COLLECT`, `BF_COLLECT`, `DF_BF_COLLECT`
+6. **聚合状态是 Final 或 Complete**（表示最后一个聚合阶段）
+7. **上游 stage 没有 P2 状态**（说明当前只有 2 阶段聚合，没有开启 3 阶段）
+
+**判断逻辑**：
+- 如果当前 stage 的 aggregate 是 **Final** 或 **Complete** 状态
+- 且上游 stage **没有 P2/PARTIAL2** 状态
+- 说明当前只有 **2 阶段聚合**（P1 → Final），需要优化为 **3 阶段**（P1 → P2 → Final）
+
+**优化建议**：
+
+1. **开启三阶段聚合**（如果未开启）：
+   ```sql
+   set cz.optimizer.incremental.df.three.phase.agg.enable = true;
+   ```
+   注意：如果已有 `cz.optimizer.df.enable.three.phase.agg=true`，则不需要重复设置
+
+2. **禁用 one-pass 聚合**（如果聚合退化为 Complete）：
+   ```sql
+   set cz.optimizer.enable.one.pass.agg = false;
+   ```
+
+3. **调整 BF bits 阈值**（如果 bits 在 512M-1G 范围内）：
+   ```sql
+   set cz.optimizer.df.three.phase.agg.bf.width.threshold = <bits值>;
+   ```
+   - 如果 `bits >= 536870912` 且 `bits < 1073741824`，需要设置此参数
+   - 默认阈值是 1073741824（1.3版本及以下），1.3以上版本默认值是 536870912
+   - 小于默认阈值不会生成 3 阶段
+   - 如果 `bits < 536870912`，不建议修改此参数
+
+**代码示例**：
+```python
+# 检查输入数据量（从 metrics 中获取）
+metrics = stage_data.get('metrics', {})
+input_bytes = metrics.get('input_bytes', 0)
+input_mb = input_bytes / (1024 * 1024)
+
+if input_mb < 20:
+    # 输入数据量太小，不需要优化
+    pass
+
+# 检查当前 stage 的聚合状态
+has_final = 'FINAL' in aggregate_mode
+has_complete = 'Complete' in aggregate_mode
+
+# 检查上游 stage 是否有 P2
+upstream_has_p2 = False
+for upstream_stage in upstream_stages:
+    if 'P2' in upstream_aggregate_mode or 'PARTIAL2' in upstream_aggregate_mode:
+        upstream_has_p2 = True
+        break
+
+# 判断是否需要优化
+if (has_final or has_complete) and not upstream_has_p2:
+    # 当前只有 2 阶段，需要开启 3 阶段优化
+    recommend_three_phase_agg = True
+```
+
+---
+
+### 4.1.2.1 Bloom Filter 收集检测（高优先级）
+
+**目的**：检测增量计算中是否缺少 Bloom Filter 收集，这会导致数据裁剪效果不佳
+
+**触发条件**：
+1. Stage 包含 **HashAggregate** 算子
+2. 聚合函数包含 `MULTI_RANGE_COLLECT`
+3. **但缺少** `_DF_BF_COLLECT` 或 `_DF_SET_BF_COLLECT` 函数
+
+**判断逻辑**：
+```python
+# 获取所有聚合函数
+agg_functions = []
+for op in operators:
+    if 'hashAgg' in op:
+        agg_calls = op['hashAgg']['aggregate']['aggregateCalls']
+        for call in agg_calls:
+            func_name = call['function']['function']['name']
+            agg_functions.append(func_name)
+
+# 检查是否有 MULTI_RANGE_COLLECT
+has_multi_range = any('MULTI_RANGE_COLLECT' in func for func in agg_functions)
+
+# 检查是否缺少 BF 收集
+has_bf_collect = any(
+    '_DF_BF_COLLECT' in func or '_DF_SET_BF_COLLECT' in func 
+    for func in agg_functions
+)
+
+# 如果有 MULTI_RANGE_COLLECT 但没有 BF 收集，则需要优化
+needs_optimization = has_multi_range and not has_bf_collect
+```
+
+**优化建议**：
+
+**对于 v1.3 版本**，添加以下完整配置：
+```sql
+set cz.optimizer.incremental.df.three.phase.agg.enable = true;
+set cz.optimizer.df.three.phase.agg.bf.width.threshold = 536870912;
+set cz.optimizer.df.bf.width.max = 2147483648;
+set cz.optimizer.df.bf.width.min = 1073741824;
+set cz.optimizer.incremental.enforce.creating.bf = true;
+```
+
+**对于其他版本**，至少添加：
+```sql
+set cz.optimizer.incremental.enforce.creating.bf = true;
+```
+
+**注意**：
+- 如果参数已经存在且值正确，则不要重复推荐
+- 这是**高优先级**优化，因为缺少 BF 会严重影响增量计算的裁剪效果
+- Bloom Filter 用于在增量计算中快速过滤不需要的数据，提升性能
+
+**代码示例**：
+```python
+# 检查版本
+version_info = context.get('version_info', {})
+git_branch = version_info.get('git_branch', '')
+is_v13 = 'release-v1.3' in git_branch
+
+# 生成推荐
+if is_v13:
+    # v1.3 版本需要完整配置
+    params = [
+        ('cz.optimizer.incremental.df.three.phase.agg.enable', 'true'),
+        ('cz.optimizer.df.three.phase.agg.bf.width.threshold', '536870912'),
+        ('cz.optimizer.df.bf.width.max', '2147483648'),
+        ('cz.optimizer.df.bf.width.min', '1073741824'),
+        ('cz.optimizer.incremental.enforce.creating.bf', 'true')
+    ]
+else:
+    # 其他版本只需要强制创建 BF
+    params = [
+        ('cz.optimizer.incremental.enforce.creating.bf', 'true')
+    ]
+
+# 检查并推荐未设置的参数
+for param, value in params:
+    if settings.get(param) != value:
+        recommend(param, value, priority='HIGH')
+```
+
+---
+
+### 4.1.3 Hash Join 优化
+
+**触发条件**：
+1. Stage 耗时 **> 10秒** 或 占总耗时 **> 8%**
+2. Stage 包含 Join operator
+3. Join 耗时 **> 30%** 的 Stage 时间
+
+**分析方法**：
+- Join 算法：从 `plan.json` 获取
+- 数据量/Shuffle 量：从 `job_profile.json` 获取
+
+**优化建议**：
+
+**IF** Join 算法 = `Broadcast Hash Join`  
+**AND** Broadcast/Shuffle 数据量异常大：
+
+搜索 settings 中 `cz.optimizer.enable.broadcast.hash.join`：
+
+**IF** 参数不存在 **OR** 值 = `true`：
+```sql
+-- 推荐
+set cz.optimizer.enable.broadcast.hash.join = false;
+```
+
+**代码示例**：
+```python
+plan_str = json.dumps(stage['operators'])
+is_broadcast = 'BroadcastHashJoin' in plan_str or 'Broadcast' in plan_str
+```
+
+---
+
+### 4.1.4 包含 TableSink 的 Stage DOP 优化
+
+**触发条件**（必须**全部**满足）：
+1. Stage 包含 **TableSink** 算子（排除 partial sink 和 DELTA sink）
+   - **Partial sink**: `flags & 0x20 != 0`
+   - **DELTA sink**: `path` 最后一个元素是 `__delta__`（4元组）
+2. Stage 耗时占总体 **> 10%**
+3. Stage DOP **与上游 DOP 差异较大**
+
+**不应推荐的情况**：
+- Stage **不包含** TableSink 算子
+- Stage DOP 与上游 DOP 接近（≥ 上游max * 0.5）
+- Stage DOP **已大于**上游 DOP（下游 DOP 都已经大于上游，无需调整）
+
+**原因推断**：
+系统可能根据**目标表文件大小**自动调整了 DOP。
+
+**优化建议**：
+
+计算上游最大 DOP：
+```python
+upstream_dops = [metrics['dop'] for sid, metrics in stages if sid != current_stage]
+max_upstream = max(upstream_dops)
+```
+
+**检查 TableSink 是否为 partial sink 或 DELTA sink**：
+```python
+# 从 plan.json 中的 TableSink 算子获取信息
+table_sink = operator.get('tableSink', {})
+flags = table_sink.get('flags', 0)
+table = table_sink.get('table', {})
+path = table.get('path', [])
+
+# 判断是否为 partial sink
+is_partial_sink = (flags & 0x20) != 0
+
+# 判断是否为 DELTA sink (path 最后一个元素是 __delta__)
+is_delta_sink = len(path) == 4 and path[-1] == '__delta__'
+
+# 只对非 partial sink 且非 DELTA sink 的 TableSink 进行 DOP 优化检查
+if is_partial_sink or is_delta_sink:
+    # 跳过
+    pass
+```
+
+**IF** `current_dop < max_upstream * 0.5` **AND** `current_dop <= max_upstream`：
+
+搜索 settings 中 `cz.sql.enable.dag.auto.adaptive.split.size`：
+
+**IF** 参数值 = `true`（已经设置该 flag 为 true 才需要）：
+```sql
+-- 推荐
+set cz.sql.enable.dag.auto.adaptive.split.size = false;
+```
+
+**注意**：
+- 该参数目的是不根据 table 的目标文件大小来自动调整 DOP
+- 如果在这种场景下，stage 里没有 tablesink 算子不要加该参数
+- 如果上游 DOP 和自己相差不大（即计算依赖 stage 的 task count），则不需要额外设置
+- 如果 stage 的 DOP 大于上游 stage 的 DOP，则也不需要调整该参数
+
+⚠️ **警告**：此参数影响全局，请谨慎使用。
+
+---
+
+### 4.1.5 最大 DOP 提示
+
+**DAG 限制**：
+- Map 最大 DOP = `4096`
+- Reduce 最大 DOP = `2048`
+
+**原则**：
+- 达到这些限制通常**不是问题**
+- **除非**用户显式调整过这些参数：
+  - `cz.optimizer.mapper.stage.max.dop`
+  - `cz.optimizer.reducer.stage.max.dop`
+
+**处理方式**：
+```python
+if stage_dop >= 4096 or stage_dop >= 2048:
+    # 检查是否用户主动设置了 max dop 参数
+    if 'cz.optimizer.mapper.stage.max.dop' in settings or \
+       'cz.optimizer.reducer.stage.max.dop' in settings:
+        # 可能需要分析
+        pass
+    else:
+        # 达到系统限制，这是正常的
+        print(f"Stage {stage_id} DOP达到系统限制，这是正常的")
+```
+
+---
+
+### 4.1.6 数据倾斜检测
+
+**目的**：检测数据倾斜问题并提供优化建议
+
+**触发条件**：
+- 少于 **5%** 的 task 有数据（即 active task 比例 < 5%）
+
+**判断方法**：
+1. 从 `job_profile.json` 的 `taskSummary` 获取每个 task 的情况
+2. 统计有数据的 task 数量（`inputBytes > 0` 或 `outputBytes > 0`）
+3. 计算 active task 比例 = active_tasks / total_tasks
+
+**优化建议**：
+
+**场景 1：Stage 包含 Scan 算子**
+
+调整 split size 以缓解倾斜：
+```sql
+set cz.mapper.file.split.size = 67108864;  -- 从默认 256M (268435456) 调整为 64M
+```
+
+**场景 2：Stage 包含 Shuffle Read**
+
+提示关注上游是否存在倾斜数据，需要检查：
+- 上游 Stage 的数据分布
+- Shuffle 分区策略
+- 是否需要调整分区键
+
+**代码示例**：
+```python
+# 检查倾斜
+task_summary = profile.get('taskSummary', {})
+total_tasks = len(task_summary)
+active_tasks = 0
+
+for task_id, task_data in task_summary.items():
+    input_bytes = task_data.get('inputBytes', 0)
+    output_bytes = task_data.get('outputBytes', 0)
+    if input_bytes > 0 or output_bytes > 0:
+        active_tasks += 1
+
+active_ratio = active_tasks / total_tasks
+is_skewed = active_ratio < 0.05  # 少于 5% 的 task 有数据
+
+if is_skewed:
+    # 检查是否有 scan 算子
+    has_scan = any('Scan' in op.get('type', '') for op in operators)
+
+    if has_scan:
+        # 建议调整 split size
+        current_split_size = settings.get('cz.mapper.file.split.size', 268435456)
+        if current_split_size >= 268435456:
+            recommend_split_size = 67108864  # 64M
+
+    # 检查是否有 shuffle read
+    has_shuffle_read = any('ShuffleRead' in op.get('type', '') for op in operators)
+
+    if has_shuffle_read:
+        # 提示关注上游倾斜
+        print("检测到 Shuffle Read，请关注上游是否存在倾斜数据")
+```
+

+
+### 4.1.7 SpillingBytes 分析
+
+**分析级别**：
+1. **Stage 级别** - 总 Spill 大小
+2. **Operator 级别** - 可以看到 `opId` 的 spill stats
+
+**数据提取**：
+```python
+# Stage 级别
+spill_bytes = stage_data['inputOutputStats']['spillingBytes']
+
+# Operator 级别
+for op_id, op_data in stage_data['operatorSummary'].items():
+    if 'spillStats' in op_data:
+        op_spill = op_data['spillStats']
+        # 分析具体算子的 spilling
+```
+
+**注意**：
+- **Shuffle Write 的 Spill 可能可以忽略**
+- 重点关注其他算子的 Spilling
+
+**分析输出**：
+```python
+if spill_bytes > 1024**3:  # > 1GB
+    print(f"Stage {stage_id} Spilling: {spill_bytes/(1024**3):.2f} GB")
+    # 分析哪个 operator 导致
+    for op_id, op_data in operators:
+        if has_spill(op_data):
+            print(f"  Operator {op_id}: {op_spill} bytes")
+```
+
+---
+
+### 4.1.8 资源效率分析
+
+**目的**：对比每个 Stage 的实际运行时间与理论资源充足情况下的预期时间，检测资源不足导致的性能问题
+
+**触发条件**：
+1. 有 profile 数据且 taskSummary 存在
+2. VC core 数有效（> 0）
+3. Stage 耗时 > 5秒
+
+**并发 Stage 资源竞争处理**：
+多个 stage 可能并发执行，共享 vc_cores 资源。分析时需要：
+1. 通过 `startTime`/`endTime` 找出与当前 stage 时间重叠的其他 stage
+2. 累加并发 stage 的 dop 作为被占用的资源
+3. 可用资源 = `max(1, vc_cores - 并发 stage 总 dop)`
+4. 用调整后的可用资源计算预期耗时
+
+**分析方法**：
+1. 从 `taskSummary` 获取每个 task 的运行时间（`endTime - startTime`）
+2. 找出最大 task 时间（`max_task_time`）
+3. 计算总 task 数
+4. 计算可用资源（扣除并发 stage 占用）
+5. 计算需要跑多少轮：`rounds = ceil(total_tasks / available_cores)`
+6. 预期耗时 = `max_task_time × rounds`
+7. 对比实际耗时与预期耗时，如果实际 > 2倍预期，则告警
+
+**VC Core 数获取**（参考 2.3）：
+```python
+# AP 模式
+vc_cores = int(settings['cz.analyze.instance.executor.count'])
+# GP 模式
+vc_cores = int(settings['cz.sql.gp.vc.capability']) // 100
+```
+
+**代码示例**：
+```python
+# 计算并发 stage 占用的资源
+concurrent_dop = 0
+for other_stage in all_stages:
+    if other_stage.id == current_stage.id:
+        continue
+    if other_stage.startTime < current_stage.endTime and other_stage.endTime > current_stage.startTime:
+        concurrent_dop += other_stage.dop
+
+available_cores = max(1, vc_cores - concurrent_dop)
+
+# 从 taskSummary 获取每个 task 的运行时间
+task_times = []
+for task_id, task_data in task_summary.items():
+    start_time = int(task_data.get('startTime', 0))
+    end_time = int(task_data.get('endTime', 0))
+    if end_time > start_time:
+        task_times.append(end_time - start_time)
+
+max_task_time = max(task_times)
+total_tasks = len(task_times)
+
+# 计算理论最优耗时（使用扣除并发后的可用资源）
+rounds = (total_tasks + available_cores - 1) // available_cores
+estimated_time = max_task_time * rounds
+
+# 对比
+efficiency_ratio = actual_elapsed / estimated_time
+if efficiency_ratio >= 2.0:
+    # 资源效率偏低，可能存在资源排队或调度开销
+    report_issue(stage_id, actual_elapsed, estimated_time, efficiency_ratio)
+```
+
+---
+
+### 4.1.9 主动问题发现（**必须执行**）
+
+**要求**：
+- **不允许**"没有发现问题"的结论
+- 必须遍历**所有 Stage**
+- 对耗时较长的 Stage 主动分析原因
+
+**分析步骤**：
+
+1. **找出 Top 耗时 Stage**（至少 Top 5）
+
+2. **对每个 Stage 分析**：
+   ```python
+   # a. 找瓶颈 Operator
+   bottleneck_op = max(operators, key=lambda op: op['max_time_ms'])
+   
+   # b. 判断原因
+   if bottleneck_op['skew_ratio'] > 5.0:
+       reason = "数据倾斜严重"
+       suggestion = "SQL 改写或数据预处理"
+   
+   elif bottleneck_op['stage_pct'] > 80:
+       reason = "单个 Operator 占主导"
+       suggestion = "检查算子逻辑或数据分布"
+   
+   elif stage_dop <= 10:
+       reason = "DOP 较低"
+       suggestion = "检查是否需要提高并行度"
+   
+   elif stage_spill > 1GB:
+       reason = f"Spilling 较大: {spill_gb:.2f} GB"
+       suggestion = "检查内存配置或数据倾斜"
+   ```
+
+3. **输出分析结果**：
+   ```
+   [分析] Stage stg11: 212.7s (77.6%)
+     瓶颈 Operator: Calc97
+       耗时: 207.9s (97.7% of Stage)
+       倾斜: 57.6x
+     → 原因: 数据倾斜严重
+     → 建议: SQL 改写或数据预处理
+   ```

+# 状态表优化指南
+
+本文档包含增量计算的状态表优化规则。
+
+这是增量优化的第二部分，基于增量算法分析的结果，提供具体的状态表优化建议。
+
+**前置依赖**：
+- 本文档的优化规则依赖于 [增量算法分析](./incremental-algorithm-analysis.md) 的结果
+- 必须先完成增量算法识别（4.2.1）才能应用这些优化规则
+
+**相关文档**：
+- [Stage/Operator 优化](./stage-operator-optimization.md) - Stage 和 Operator 级别优化
+- [增量算法分析](./incremental-algorithm-analysis.md) - 增量算法识别和分析（必读）
+- [优化原则](./optimization-principles.md) - 参数推荐原则
+
+---
+
+## 状态表优化规则
+
+### 4.2.2 非增量原因诊断
+
+**触发条件**：
+- Job **非增量刷新**（根据 4.2.1 判断）
+
+**推荐操作**（根据版本选择）：
+
+#### 版本 <= 1.3
+
+**IF** job 非增量刷新 **AND** 版本 <= 1.3：
+```sql
+-- 推荐设置以下 flag 后重新执行 EXPLAIN REFRESH
+set cz.optimizer.print.non.incremental.reason = true;
+set cz.optimizer.print.non.incremental.reason.msg.max.length = 100000;
+set cz.optimizer.incremental.force.incremental = true;
+```
+
+**THEN** 执行：
+```sql
+EXPLAIN REFRESH <表名>;
+```
+
+查看输出以了解为什么退化为全量刷新。
+
+#### 版本 >= 1.4
+
+**IF** job 非增量刷新 **AND** 版本 >= 1.4：
+```sql
+-- 推荐设置以下 flag
+set cz.optimizer.incremental.try.incremental.refresh.enabled = true;
+```
+
+**THEN** 重新执行查询，系统会提示为什么没有走增量。
+
+**版本判断**：
+- 从 `plan.json` 的 `build_info` 或 `settings['build_info']` 中获取 `GitBranch` 信息
+- 例如：`GitBranch:release-v1.3` → 版本 1.3
+- 例如：`GitBranch:release-v1.4` → 版本 1.4
+
+---
+
+### 4.2.3 Window 算子在 append-only delta 输入时的优化
+
+**目的**：优化 window 算子在 append-only delta 输入时的性能
+
+**⚠️ 重要前提**：
+- 根据 prompt 4.2.0 要求："同时关于状态表这些优化必须是对应算子的对应增量算法"
+- **只有带增量 hint 的 window 算子才需要分析**
+- 没有增量 hint 的 window 算子不是增量算法的一部分，应该跳过
+
+**检查步骤**：
+
+#### 步骤 0: 检查是否为增量算法的 window
+
+**首先检查 window 算子是否有增量相关的 hint**：
+```python
+def has_incremental_hint(op):
+    """检查是否有增量相关的 hint"""
+    op_str = json.dumps(op)
+    
+    incremental_patterns = [
+        'IncrementalLinearTopKWindowRule',
+        'IncrementalLinearTopKWindowRuleV2', 
+        'IncrementalWindowSetDeltaRule',
+        'Rule:Incremental',
+        'DeltaState',
+        'HINT=delta'
+    ]
+    
+    return any(pattern in op_str for pattern in incremental_patterns)
+
+# 只处理有增量 hint 的 window
+if not has_incremental_hint(window_op):
+    continue  # 跳过，不是增量算法的 window
+```
+
+**示例**：
+- ✅ **需要处理**：`HINT=delta,DeltaState-:[0,0]_IncrementalLinearTopKWindowRuleV2`
+- ❌ **跳过处理**：普通的 `PhysicalWindow([ROW_NUMBER()])` 没有增量 hint
+
+#### 步骤 1: 检查 window 算子的父节点
+
+检查 window 算子的父节点是否是 calc，且存在 `row number=1` 的 pattern。
+
+**rn=1 pattern 识别方法**：
+
+可以通过以下两种方式识别：
+
+1. **简单字符串匹配**（向后兼容）：
+   - 查找 'ROW_NUMBER', 'row_number', 'rn=1', 'rn = 1' 等字符串
+
+2. **JSON 结构匹配**（推荐）：
+   - 查找 EQ function，其中 constant.bigint = "1"
+   - EQ 表示等于 (=)，constant 有个值 bigint:1 表示是 1
+   - 所以对应的其实就是 xx=1
+
+**JSON 结构示例**：
+```json
+{
+  "function": {
+    "from": "",
+    "name": "EQ",
+    "builtIn": true,
+    "arguments": [
+      {
+        "reference": {
+          "id": "0",
+          "local": false,
+          "from": "",
+          "name": "",
+          "refType": "LOGICAL_FIELD"
+        },
+        "typeReference": 1
+      },
+      {
+        "constant": {
+          "bigint": "1"
+        },
+        "typeReference": 1
+      }
+    ],
+    "properties": {"properties": []},
+    "execDesc": "EQ(i64,i64)->b",
+    "functionProperties": {"properties": []}
+  },
+  "pt": {
+    "start": {"line": 1, "col": 7356, "pos": 7355},
+    "end": {"line": 1, "col": 7364, "pos": 7363}
+  },
+  "typeReference": 13
+}
+```
+
+**代码示例**：
+```python
+# 查找 window 算子
+for idx, op in enumerate(operators):
+    if 'window' in json.dumps(op).lower():
+        # 检查父节点（下游算子）
+        for parent_idx in range(idx + 1, len(operators)):
+            parent_op = operators[parent_idx]
+            if 'calc' in json.dumps(parent_op).lower():
+                # 方法1: 简单字符串匹配
+                parent_str = json.dumps(parent_op)
+                if 'ROW_NUMBER' in parent_str or 'rn=1' in parent_str or 'rn = 1' in parent_str:
+                    has_rn_pattern = True
+                    break
+
+                # 方法2: JSON 结构匹配（查找 EQ function with constant.bigint="1"）
+                if check_eq_one_pattern(parent_op):
+                    has_rn_pattern = True
+                    break
+```
+
+#### 步骤 2: 检查 window 的输入是否是 append-only delta
+
+使用 **4.2.1.5** 的方法检查 window 算子的输入是否是 append-only。
+
+从 window 算子向上游遍历，找到所有 TableScan：
+
+```python
+def check_append_only_input(window_idx):
+    visited = set()
+    append_only_tables = {}
+
+    def dfs(idx):
+        if idx in visited:
+            return
+        visited.add(idx)
+
+        op = operators[idx]
+
+        # 如果是 tablescan，检查是否是 append-only
+        if 'tableScan' in op:
+            table_scan = op['tableScan']
+            table_name = table_scan.get('table', {}).get('name', 'unknown')
+
+            # 检查实际输出的列（operator的schema），而不是表定义的完整schema
+            operator_schema = op.get('schema', {})
+            struct_info = operator_schema.get('structTypeInfo', {})
+            fields = struct_info.get('fields', [])
+            # 检查是否输出 __incremental_deleted 列（注意是过去式）
+            has_delete_col = any(f.get('name') == '__incremental_deleted' for f in fields)
+
+            if not has_delete_col:
+                # 是 append-only
+                append_only_tables[table_name] = True
+
+        # 继续向上游遍历
+        for input_idx in get_inputs(idx):
+            dfs(input_idx)
+
+    dfs(window_idx)
+    return len(append_only_tables) > 0, append_only_tables
+```
+
+#### 步骤 3: 优化建议
+
+检查 window 算子是否包含 `IncrementalLinearTopKWindowRule` hint：
+```python
+window_str = json.dumps(window_op)
+# 支持 V1 和 V2 版本的规则
+uses_linear_topk_rule = ('IncrementalLinearTopKWindowRule' in window_str or 
+                        'IncrementalLinearTopKWindowRuleV2' in window_str)
+```
+
+**IF** window 输入是 append-only **AND** 是 `rn=1` 的 pattern：
+
+**情况 1：已使用 IncrementalLinearTopKWindowRule**
+```python
+if uses_linear_topk_rule:
+    # 这是期望的行为，无需优化
+    print("Window 算子已正确使用 IncrementalLinearTopKWindowRule 增量算法")
+```
+
+**情况 2：未使用 IncrementalLinearTopKWindowRule**
+```python
+if not uses_linear_topk_rule:
+    # 需要优化：禁用竞争规则以启用 IncrementalLinearTopKWindowRule
+    param = 'cz.optimizer.incremental.window.sd.to.sd.rule.enable'
+    if param not in settings or settings.get(param) == 'true':
+        # 推荐设置
+        print("set cz.optimizer.incremental.window.sd.to.sd.rule.enable = false;")
+```
+
+**优化逻辑说明**：
+- `cz.optimizer.incremental.window.sd.to.sd.rule.enable=false` 禁用其他 window 规则
+- 这样可以让 `IncrementalLinearTopKWindowRule` 被选中使用
+- 只有在 append-only + rn=1 场景下且未使用 linear rule 时才推荐
+
+#### 步骤 4: 检查表 Property
+
+**IF** 输入表是 Append-only：
+
+检查 tablescan 的 table 属性是否有 `incr.append.only.table=true`：
+
+```python
+table_scan = op['tableScan']
+table_properties = table_scan.get('table', {}).get('properties', {})
+has_property = table_properties.get('incr.append.only.table') == 'true'
+```
+
+**IF** 没有设置：
+
+检查 job 是否有 flag `cz.optimizer.incremental.append.only.tables`：
+
+```python
+append_only_setting = settings.get('cz.optimizer.incremental.append.only.tables', '')
+if table_name not in append_only_setting:
+    # 缺少 append-only hint
+```
+
+**推荐**：
+```
+⚠️ 提醒用户添加：
+ALTER TABLE <表名> SET TBLPROPERTIES ('incr.append.only.table' = 'true');
+-- 或
+set cz.optimizer.incremental.append.only.tables = '<表名>';
+```
+
+---
+
+### 4.2.4 Append-only Scan 检查
+
+**目的**：检查当前 query 是否还包含 Append-only 的 scan，并预判算法是否最优
+
+**核心思想**：
+如果系统中仍然存在对 append-only 数据的扫描，说明可能没有充分利用 append-only 特性进行优化。理想情况下，append-only 数据应该通过增量算法处理，而不是重复扫描。
+
+**检查逻辑**：
+
+1. **识别 Append-only Delta 表**：
+   ```python
+   # 检查 TableScan 是否为 delta 表且不包含 __incremental_deleted 列（注意是过去式）
+   # 检查位置：算子的实际输出列（operator.schema.structTypeInfo.fields）
+   is_delta_table = (len(path) == 4 and path[-1] == '__delta__') or '__delta__' in table_name
+   operator_schema = op.get('schema', {})
+   struct_info = operator_schema.get('structTypeInfo', {})
+   cols = [f.get('name') for f in struct_info.get('fields', [])]
+   is_append_only = '__incremental_deleted' not in cols
+   ```
+
+2. **分析优化机会**：
+   
+   **IF** 发现 Append-only scan **AND** 有 Join/Aggregate 操作：
+   
+   a) **状态表检查**：
+   ```python
+   state_table_enabled = settings.get('cz.optimizer.incremental.enable.state.table', 'false') == 'true'
+   if not state_table_enabled:
+       # 建议：考虑启用状态表以避免重复扫描 append-only 数据
+   ```
+   
+   b) **增量算法检查**：
+   ```python
+   has_incremental_hints = any(pattern in plan_str for pattern in [
+       'IncrementalLinearTopKWindowRule',
+       'IncrementalAggregateRule', 
+       'IncrementalJoinRule',
+       'Rule:Incremental',
+       'DeltaState'
+   ])
+   if not has_incremental_hints:
+       # 建议：可能可以使用增量计算替代全量扫描
+   ```
+   
+   c) **综合评估**：
+   ```python
+   if not has_incremental_hints and not state_table_enabled:
+       # 建议：append-only 数据特性未被充分利用，建议使用增量处理
+   ```
+
+**优化建议逻辑**：
+
+- **问题**：为什么还在扫描 append-only 数据？
+- **期望**：append-only 数据应该通过增量算法高效处理
+- **建议**：
+  1. 启用状态表避免重复扫描
+  2. 使用增量算法替代全量扫描  
+  3. 充分利用 append-only 数据特性
+
+**示例输出**：
+```
+💡 Stage stg11: 表 ws1.namespace.table_a 是 append-only
+[INFO] POTENTIAL_OPTIMIZATION - Stage stg11
+       append-only 表 ws1.namespace.table_a 仍在进行扫描，
+       考虑启用状态表以避免重复扫描 append-only 数据; 
+       未检测到增量算法 hint，可能可以使用增量计算替代全量扫描; 
+       append-only 数据特性未被充分利用，建议使用增量处理
+```
+
+---
+
+### 4.2.5 状态表启用建议
+
+**目的**：判断是否应该开启状态表以优化增量计算
+
+**规则类型**：GlobalRule（全局规则，只执行一次）
+
+**执行时机**：在"阶段2: 全局规则分析"中执行，不针对单个stage，而是分析整个job
+
+**检查步骤**：
+
+#### 步骤 1: 检查是否包含中间状态表
+
+在整个 job 的所有 stage 中搜索表名包含 `__incr__` pattern 的 TableSink。
+
+```python
+def _check_job_has_state_table(context):
+    """检查整个 job 是否已经包含中间状态表"""
+    aligned_stages = context.get('aligned_stages', {})
+    
+    # 检查所有 stage 的 plan
+    for stage_id, stage_data in aligned_stages.items():
+        plan = stage_data.get('plan', {})
+        plan_str = json.dumps(plan)
+        if '__incr__' in plan_str:
+            return True
+            
+    return False
+```
+
+**IF** 已包含中间状态表：
+- 无需进一步检查
+- 输出：`Job 已包含中间状态表（表名包含 __incr__）`
+
+**注意**：此检查是全局的，不仅检查当前 stage，而是检查整个 job 的所有 stage。这避免了在某些 stage 中状态表已存在但其他 stage 仍建议开启状态表的误判。
+
+#### 步骤 2: 判断是否值得存储中间状态
+
+**考虑因素**：
+
+1. **是否需要状态**（参考流计算的带状态计算定义）：
+   - 有聚合计算（SUM, COUNT, MIN, MAX）
+   - 有 Window 函数
+   - 有 JOIN（需要保存 Join 状态）
+
+   **重要**：只检查增量算法产生的算子，根据 prompt 4.2.1.2 要求：
+   ```python
+   def _get_incremental_stateful_ops(plan):
+       """获取增量算法产生的状态算子列表"""
+       incremental_stateful_ops = []
+       operators = plan.get('operators', [])
+       
+       for op in operators:
+           # 检查是否有增量 hint
+           if not _has_incremental_hint(op):
+               continue
+               
+           # 检查算子类型并匹配对应的增量算法
+           op_str = json.dumps(op)
+           
+           # Join 算子：检查是否有对应的 Join 增量算法
+           if ('Join' in op_str or 'HashJoin' in op_str) and 'Join' not in incremental_stateful_ops:
+               join_patterns = [
+                   'IncrementalJoinRule',
+                   'Rule:Incremental.*Join',
+                   'Rule:DeletePlan-delta-join'
+               ]
+               if any(pattern in op_str for pattern in join_patterns):
+                   incremental_stateful_ops.append('Join')
+           
+           # Aggregate 算子：检查是否有对应的 Aggregate 增量算法
+           elif ('HashAggregate' in op_str or 'Aggregate' in op_str) and 'HashAggregate' not in incremental_stateful_ops:
+               agg_patterns = [
+                   'IncrementalAggregateRule',
+                   'IncrementalLinearFunctionAggregateRule',
+                   'Rule:Incremental.*Aggregate',
+                   'Rule:Incremental.*Agg'
+               ]
+               if any(pattern in op_str for pattern in agg_patterns):
+                   incremental_stateful_ops.append('HashAggregate')
+           
+           # Window 算子：检查是否有对应的 Window 增量算法
+           elif ('Window' in op_str or 'HashWindow' in op_str) and 'Window' not in incremental_stateful_ops:
+               window_patterns = [
+                   'IncrementalLinearTopKWindowRule',
+                   'IncrementalLinearTopKWindowRuleV2',
+                   'IncrementalWindowSetDeltaRule',
+                   'Rule:Incremental.*Window'
+               ]
+               if any(pattern in op_str for pattern in window_patterns):
+                   incremental_stateful_ops.append('Window')
+       
+       return incremental_stateful_ops
+
+   if not incremental_stateful_ops:
+       # 不包含增量算法产生的状态算子，无需开启状态表
+       return
+   ```
+
+   **新增要求**：需要区分增量算法是不是对应的增量算法，如：
+   - Join 算子对应的 rule 是 join 相关的增量算法
+   - Aggregate 算子对应的 rule 是 aggregate 相关的增量算法  
+   - Window 算子对应的 rule 是 window 相关的增量算法
+   - 除非是第一次出现 hint 的 operator，否则应该都有对应关系
+   - 不要错误把一些增量算法的中间算子当作自己本身
+   
+   **重要**：使用 `elif` 确保每个算子只能匹配一种类型，避免一个算子被错误地归类为多种类型。例如，一个 Join 算子如果有 Aggregate 相关的 rule，不应该被当作 Aggregate 算子处理。
+
+#### 步骤 3: 两个正交的状态表优化策略
+
+**策略1：基于增量算法的状态表优化**
+- 通过程序级别的参数控制是否启用，不依赖被分析job的参数
+- 控制方式：
+  - 调用时传入：`context['enable_incremental_algorithm_analysis'] = True`
+  - 环境变量：`ENABLE_INCREMENTAL_ALGORITHM_ANALYSIS=true`
+  - 配置文件：`analysis.enable_incremental_algorithm = true`
+  - 命令行参数：`--enable-incremental-algorithm`
+- 默认不启用，避免浪费分析时间
+- 检查是否包含增量算法产生的状态算子（HashAggregate, Window, Join）
+
+**策略2：基于Snapshot Subplan占比的状态表优化（最重要）**
+- **核心原理**：中间表之所以要创建不就是因为它计算的subplan是类似跑了全量，所以才需要的，这个是最重要的
+- 总是执行，因为这是最重要的判断依据
+- 基于operator级别的链路关系，不是stage级别
+- 结合3.6的operator统计和4.2.1的delta/snapshot分析
+- 找到某个subplan（root节点是snapshot）的统计耗时占比
+
+**程序级别控制示例**：
+```bash
+# 方式1：命令行参数控制（推荐）
+python analyze_job.py plan.json job_profile.json --enable-incremental-algorithm
+
+# 方式2：同时启用状态表分析和增量算法策略
+python analyze_job.py plan.json job_profile.json --enable-state-table --enable-incremental-algorithm
+
+# 方式3：只启用状态表分析（不启用增量算法策略）
+python analyze_job.py plan.json job_profile.json --enable-state-table
+```
+
+**参数传递链路**：
+```
+命令行参数 --enable-incremental-algorithm
+    ↓
+analyze_job.py 中的 enable_incremental_algorithm_analysis 参数
+    ↓
+context['enable_incremental_algorithm_analysis'] = True
+    ↓
+StateTableEnable.analyze() 中读取并控制策略启用
+```
+
+**代码实现**：
+```python
+# analyze_job.py
+def analyze_job(plan_file, profile_file, output_dir=".", 
+               enable_state_table_analysis=False,
+               enable_incremental_algorithm_analysis=False):
+    # ...
+    analyzer.context['enable_incremental_algorithm_analysis'] = enable_incremental_algorithm_analysis
+
+# state_table_enable.py  
+def analyze(self, stage_data, context):
+    enable_incremental_strategy = context.get('enable_incremental_algorithm_analysis', False)
+    if enable_incremental_strategy:
+        # 执行增量算法策略分析
+        pass
+```
+
+**重要说明**：
+- 这是分析程序自己的控制参数，不是被分析job的参数
+- 不会推荐用户设置新的job参数（遵循prompt第8条）
+- 只推荐已知有效的job参数：`cz.optimizer.incremental.enable.state.table=true`
+
+**Snapshot Subplan分析逻辑**：
+```python
+def _find_snapshot_subplans(operator_data_types, operator_analysis, context):
+    """
+    找到root节点是snapshot的subplan
+    
+    1. 结合3.6的operator统计和4.2.1的delta/snapshot分析
+    2. 基于operator级别的链路关系，不是stage级别  
+    3. 找到某个subplan（root节点是snapshot）的统计耗时占比
+    """
+    # 找到所有snapshot类型的operator作为潜在的root节点
+    snapshot_operators = [op_id for op_id, data_type in operator_data_types.items() 
+                         if data_type == 'snapshot']
+    
+    # 获取operator依赖关系（来自增量算法分析器）
+    operator_dependencies = _get_operator_dependencies(context)
+    
+    subplans = []
+    for root_op in snapshot_operators:
+        # 从root节点开始，找到整个snapshot subplan
+        subplan_ops = _trace_snapshot_subplan(root_op, operator_data_types, operator_dependencies)
+        
+        # 计算subplan的总耗时占比
+        total_time_ms = sum(op_time_map[op_id]['elapsed_ms'] for op_id in subplan_ops)
+        percentage = (total_time_ms / total_job_time * 100)
+        
+        if percentage >= 15.0:
+            # 推荐创建中间状态表
+            pass
+    
+    return subplans
+```
+
+**策略执行逻辑**：
+```python
+def analyze_global(self, context: Dict) -> Dict:
+    """全局分析：分析整个job的snapshot subplan（只执行一次）"""
+    
+    # 策略1：基于增量算法的状态表优化（程序控制是否启用）
+    enable_incremental_strategy = context.get('enable_incremental_algorithm_analysis', False)
+    if enable_incremental_strategy:
+        incremental_result = self._analyze_incremental_algorithm_strategy_global(context)
+        # 合并结果
+    
+    # 策略2：基于Snapshot subplan占比的状态表优化（总是执行，最重要）
+    snapshot_result = self._analyze_snapshot_subplan_strategy(context)
+    # 合并结果
+    
+    return results
+```
+
+**关键改进（2024年修复）**：
+1. **全局分析**：StateTableEnable 改为 GlobalRule，只执行一次，不是每个stage执行一次
+2. **公共节点处理**：对于全snapshot的subplan，公共节点也属于subplan（不跳过processed_operators）
+3. **具体物化信息**：输出具体的root节点和所在stage，如"建议在 Stage stg18 的算子 HashJoin27 处物化为中间状态表"
+4. **详细日志**：每个subplan都打印完整信息（序号、root、stage、占比、算子数量、决策）
+
+**日志输出示例**：
+```
+[INFO] [StateTableEnable] 开始全局分析
+[INFO] [StateTableEnable] Snapshot策略 - 找到 5 个 snapshot subplan
+
+[INFO] Snapshot策略 - Subplan 1/5: Root=HashJoin27 (Stage stg18), 占比=28.9% (52468ms / 181357ms), 包含13个算子
+[INFO] Snapshot策略 - ✓ Subplan 1 占比 28.9% >= 15%，建议在 Stage stg18 的算子 HashJoin27 处物化为中间状态表
+
+[INFO] Snapshot策略 - Subplan 2/5: Root=HashJoin154 (Stage stg14), 占比=6.8% (12389ms / 181357ms), 包含12个算子
+[INFO] Snapshot策略 - ✗ Subplan 2 占比 6.8% < 15%，不建议创建状态表
+
+[INFO] [StateTableEnable] 全局分析完成: 总共 1 findings, 1 recommendations
+```
+
+**输出示例**：
+```
+[增量策略] 包含 HashAggregate，状态表大小预估合理，建议开启状态表以避免重复计算
+[Snapshot策略] 发现高占比subplan (18.5%)：Aggregate(SUM,COUNT, 1200ms) -> Join(INNER, 800ms) -> TableScan(ws1.test_table, 500ms)
+```
+
+**Snapshot 骨架输出**：
+- 同时打印出该 snapshot 的"骨架"，即把重要算子打印出来，如 aggregate/join/window/tablescan
+- aggregate 打印出聚集函数，window 类似
+- 这样方便从原始 sql 找到对应的 sql，这样 join 等就知道是从哪个 tablescan 开始到哪里结束需要创建中间表
+
+```python

+    
+    # 按重要性和耗时排序

+        }
+        skeleton.append(skeleton_item)
+    
+    return skeleton
+```
+
+**输出示例**：
+```
+Stage stg5: Snapshot 算子占比 18.5% >= 15%，建议开启状态表以减少重复计算
+Stage stg5: Snapshot 算子骨架：Aggregate(SUM,COUNT, 1200ms) -> Join(INNER, 800ms) -> TableScan(ws1.test_table, 500ms)
+```
+
+   **增量 hint 检查**：
+   ```python
+   def _has_incremental_hint(op):
+       """检查算子是否有增量相关的 hint"""
+       op_str = json.dumps(op)
+       incremental_patterns = [
+           'IncrementalLinearTopKWindowRule',
+           'IncrementalLinearTopKWindowRuleV2', 
+           'IncrementalWindowSetDeltaRule',
+           'IncrementalAggregateRule',
+           'IncrementalJoinRule',
+           'Rule:Incremental',
+           'DeltaState',
+           'HINT=delta'
+       ]
+       
+       for pattern in incremental_patterns:
+           if pattern in op_str:
+               return True
+       return False
+   ```
+
+2. **状态表是否会过大**：
+   - 根据每一步的 stats 信息（inputBytes, outputBytes）
+   - 根据输入表的增量数据大小
+   - 判断状态表大小是否可接受
+
+   ```python
+   output_bytes = metrics.get('output_bytes', 0)
+   input_bytes = metrics.get('input_bytes', 0)
+
+   if input_bytes == 0:
+       # 无法判断，保守建议开启
+       should_enable = True
+   else:
+       size_ratio = output_bytes / input_bytes
+       STATE_SIZE_RATIO_THRESHOLD = 10  # 阈值
+
+       if size_ratio > STATE_SIZE_RATIO_THRESHOLD:
+           # 状态表可能过大
+           should_enable = False
+           reason = f"状态表可能过大（输出/输入比例={size_ratio:.1f}x，阈值={STATE_SIZE_RATIO_THRESHOLD}x）"
+       else:
+           # 状态表大小合理
+           should_enable = True
+           reason = f"包含 {', '.join(stateful_ops)}，状态表大小预估合理（输出/输入比例={size_ratio:.1f}x）"
+   ```
+
+#### 步骤 3: 推荐参数
+
+**IF** 不包含状态表 **AND** 值得存储中间状态：
+
+搜索 settings 中 `cz.optimizer.incremental.enable.state.table`：
+
+**IF** 参数不存在 **OR** 值 = `false`：
+```sql
+-- 推荐
+set cz.optimizer.incremental.enable.state.table = true;
+```
+
+**附加说明**：
+```
+状态表大小预估: <size> GB
+增量数据大小: <delta_size> GB
+建议: 开启状态表可以避免重复计算
+```

+
+### 4.2.6 Aggregate 复用检查
+
+**目的**：检查 Aggregate 计算是否利用了之前的计算结果
+
+**期望行为**：
+- **SUM, COUNT**: 无论如何都应尽量使用之前的结果
+- **MIN, MAX**: 在 Append-only 情况下应尽量使用之前的结果
+
+**检查步骤**：
+
+#### 步骤 1: 找到原始 SQL 的 Aggregate operator
+
+**重要**：aggregate 必须设置上了 hint 包含类似 4.2.1.2 的一些状态 hint。
+
+如果不包含，说明该 aggregate 算子不是原始 sql 中的 aggregate，而是其他优化器 rule 等自己生成的，这些不需要检查。
+
+```python
+def has_incremental_hint(op):
+    """检查算子是否有增量 hint"""
+    op_str = json.dumps(op)
+
+    # 检查是否包含增量相关的 Rule hint
+    incremental_patterns = [
+        'IncrementalLinearFunctionAggregateRule',
+        'IncrementalAggPositiveDeltaDedupRule',
+        'IncrementalAggregate',
+        'Rule:Incremental.*Aggregate',
+        'Rule:Incremental.*Agg'
+    ]
+
+    for pattern in incremental_patterns:
+        if pattern in op_str:
+            return True
+
+    return False
+
+# 过滤掉增量算法的辅助 aggregate
+for op in stage['operators']:
+    if 'hashAgg' in op or 'hashAggregate' in op:
+        # 检查是否是辅助 aggregate（P1/P2 阶段）
+        if is_incremental_helper_aggregate(op):
+            continue
+
+        # 检查是否有增量 hint
+        if not has_incremental_hint(op):
+            continue  # 不是原始 SQL 的 aggregate
+
+        # 提取 aggregate 函数
+        agg_calls = op['hashAgg']['aggregate']['aggregateCalls']
+        for call in agg_calls:
+            func_name = call['function']['function']['name']
+            # 检查是否是 SUM, COUNT, MIN, MAX
+```
+
+#### 步骤 2: 检查是否利用了之前的计算结果
+
+在 Aggregate 的 properties 或上游 Scan 中查找增量计算相关标识。
+
+```python
+def check_incremental_markers(plan):
+    """检查是否有增量标记"""
+    plan_str = json.dumps(plan).lower()
+    return any(m in plan_str for m in ['incremental', 'delta', 'state', 'partial_result'])
+
+has_incremental_marker = check_incremental_markers(plan)
+```
+
+**IF** 发现没有复用之前的结果：
+
+#### 步骤 3: 检查是否存在状态
+
+使用 **4.2.5** 的方法检查状态表。
+
+```python
+def check_state_table_exists(plan):
+    """检查是否存在状态表"""
+    plan_str = json.dumps(plan)
+    return '__incr__' in plan_str
+
+has_state_table = check_state_table_exists(plan)
+```
+
+**IF** 状态不存在：
+```
+⚠️ 建议：可能缺少状态表，建议设置 cz.optimizer.incremental.enable.state.table=true
+```
+
+#### 步骤 4: 检查是否有 Append-only 输入
+
+使用 **4.2.1.5** 的方法检查 aggregate 的输入是否是 append-only。
+
+```python
+def check_append_only_inputs(plan, agg_idx):
+    """检查 aggregate 的输入是否是 append-only"""
+    # 从 aggregate 向上游遍历，找到所有 tablescan
+    # 检查实际输出的列（operator.schema.structTypeInfo.fields）
+    # 检查是否输出 __incremental_deleted 列（注意是过去式）
+    # 如果没有输出，则是 append-only
+    pass
+
+is_append_only = check_append_only_inputs(plan, agg_idx)
+```
+
+**IF** 是 Append-only **BUT** 缺少系统 hint：
+
+```
+⚠️ 建议补充 hint:
+ALTER TABLE <表名> SET TBLPROPERTIES ('incr.append.only.table' = 'true');
+-- 或
+set cz.optimizer.incremental.append.only.tables = '<表名>';
+```
+
+#### 步骤 5: 分析不同聚集函数
+
+**对于 SUM, COUNT**：
+- 无论如何都应该使用之前的结果
+- 如果没有复用，给出 WARNING 级别的 finding
+
+**对于 MIN, MAX**：
+- 在 append-only 情况下应该使用之前的结果
+- 如果是 append-only 但没有复用，给出 INFO 级别的 finding
+
+**示例输出**：
+```
+发现 Aggregate: SUM(amount)
+检查: 没有利用之前的计算结果
+原因: 输入表 orders 是 Append-only 但缺少 hint
+建议: 添加 'incr.append.only.table' = 'true' property
+```
+

+
+### 4.2.7 Calc 状态优化
+
+**触发条件**（必须**全部**满足）：
+1. Calc operator 占其所属 Stage 耗时 **> 30%**
+2. 该 Stage 占整体耗时 **> 10%**
+
+**检查步骤**：
+
+#### 步骤 1: 识别高耗时 Calc
+
+```python
+for op in operator_analysis:
+    if 'Calc' in op['operator_id']:
+        if op['stage_pct'] > 30 and stage_total_pct > 10:
+            # 触发优化检查
+```
+
+#### 步骤 2: 分析 Calc 内容
+
+在 plan 中查看 Calc operator 的详细内容：
+
+```python
+calc_op = find_operator(plan, 'calc')
+expressions = calc_op['calc']['expressions']
+
+# 检查是否有高成本函数
+for expr in expressions:
+    if is_udf(expr) or is_complex_function(expr):
+        has_heavy_calc = True
+```
+
+#### 步骤 3: 特别关注 UDF
+
+**IF** Calc 包含**用户自定义函数（UDF）**：
+- UDF 通常耗时较长
+- 非常适合通过状态表优化
+
+#### 步骤 4: 推荐参数
+
+**IF** 发现高耗时 Calc（特别是包含 UDF）：
+
+搜索 settings 中 `cz.optimizer.incremental.create.rule.based.table.on.heavy.calc`：
+
+**IF** 参数不存在 **OR** 值 = `false`：
+```sql
+-- 推荐
+set cz.optimizer.incremental.create.rule.based.table.on.heavy.calc = true;
+```
+
+**示例输出**：
+```
+发现高耗时 Calc: Calc25
+  Stage 占比: 45.2%
+  整体占比: 12.3%
+  包含 UDF: my_custom_transform()
+建议: 开启 Calc 状态优化
+  set cz.optimizer.incremental.create.rule.based.table.on.heavy.calc = true;
+```
+
+#### 步骤 5: 显示所有满足的优化模式
+
+**重要**：总体所有满足这些优化 pattern 的（4.2.3-4.2.7），请可以显示出来，提供查看。
+
+这包括：
+- 4.2.3: Window 算子在 append-only delta 输入时的优化机会
+- 4.2.4: 基于 append-only scan 的优化机会
+- 4.2.5: 中间状态表创建的优化机会
+- 4.2.6: Aggregate linear rule 优化机会
+- 4.2.7: Calc 状态优化机会
+
+**输出格式**：
+```
+优化机会总览：
+1. [Window优化] Stage 3: Window 算子输入是 append-only 且有 rn=1 pattern
+2. [状态表优化] Stage 5: Aggregate SUM/COUNT 可以利用状态表
+3. [Calc优化] Stage 7: Calc 包含 UDF，占比 45.2%
+...
+```

+## 可用 scripts 参数
+
+| 脚本参数                                       | 用途 |
+|--------------------------------------------|------|
+| `check_abandoned --table <name> --days 30` | 检查废弃表 |
+| `check_write_history --table <name>`       | 检查写入历史 |
+| `get_table_properties --table <name>`      | 获取表属性（含 Compaction 配置） |
+| `check_files --table <name>`               | 检查非分区表文件数量 |
+| `check_partitions --table <name>`          | 检查分区表文件分布 |
+| `optimize --table <name> --type <type>`    | 生成优化 SQL |
+
+---
+
+## Compaction 优化流程
+
+### Step 1: 获取表属性
+
+```bash
+python scripts/table_optimizer.py get_table_properties --table schema.table_name
+```
+
+从输出判断：
+- `# Partition Information` 存在 → 分区表
+- `properties` 字段 → 现有 Compaction 配置
+- `statistics` 字段 → 表大小（byte）
+
+### Step 2: 根据表类型诊断
+
+**非分区表**：
+```bash
+python scripts/table_optimizer.py check_files --table schema.table_name
+```
+
+**分区表**：
+```bash
+python scripts/table_optimizer.py check_partitions --table schema.table_name
+```
+
+**小文件问题判断标准**（参考值，非硬性阈值）：
+
+| 指标 | 参考值 | 说明 |
+|-----|-------|------|
+| 平均文件大小 | ~768MB | 低于此值可能存在小文件问题 |
+| 文件数量 | ~10 个 | 高于此值且平均文件较小时需关注 |
+
+**判断逻辑**：
+- ✅ 明显需要优化：平均文件大小 << 768MB **且** 文件数量 >> 10
+- ⚠️ 边界情况：接近参考值时（如 700MB、12 个文件），可灵活判断
+- ❌ 无需优化：平均文件大小接近或超过 768MB，或文件数量较少
+
+**示例**：
+- 表大小 5GB，文件数 100 → 平均 50MB → ✅ 明显需要优化
+- 表大小 8GB，文件数 12 → 平均 ~670MB → ⚠️ 边界情况，可观察
+- 表大小 1GB，文件数 5 → 平均 200MB，文件数少 → ❌ 不需优化
+- 表大小 100GB，文件数 50 → 平均 2GB → ❌ 平均文件大小足够
+
+### Step 3: 生成优化 SQL（如需优化）
+
+⚠️ **参数配置原则**：
+- 先从 Step 1 的 `properties` 字段获取当前配置值
+- 如果**没有配置**：使用默认值（`min-interval=1800`，`partition-window=3600`）
+- 如果**已有配置但需要调小**：在当前值基础上调整（如当前 3600 → 调整为 1800）
+- **不要覆盖用户已有的合理配置**
+
+**非分区表**（DML 模式）：
+```bash
+# 默认值（无现有配置时）
+python scripts/table_optimizer.py optimize --table schema.table_name --type compaction_daily --min-interval 1800
+
+# 如果当前 cz.compaction.min.interval=3600，需要调小
+python scripts/table_optimizer.py optimize --table schema.table_name --type compaction_daily --min-interval 1800
+```
+
+**分区表**（DML + Background 模式）：
+```bash
+# 默认值（无现有配置时）
+python scripts/table_optimizer.py optimize --table schema.table_name --type compaction_hourly --min-interval 1800 --partition-window 3600
+
+# 根据现有配置调整示例：
+# - 当前 min.interval=3600 → 调整为 1800
+# - 当前 partition.window=7200 → 调整为 3600
+python scripts/table_optimizer.py optimize --table schema.table_name --type compaction_hourly --min-interval 1800 --partition-window 3600
+```
+
+**参数调整决策表**：
+
+| 当前配置 | 小文件问题 | 建议操作 |
+|---------|-----------|---------|
+| 无配置 | 有 | 使用默认值：`min-interval=1800`, `partition-window=3600` |
+| `min.interval=3600` | 有 | 调小为 `1800` |
+| `min.interval=1800` | 有 | 保持不变，建议手动触发 OPTIMIZE |
+| `partition.window=7200` | 有 | 调小为 `3600` |
+| `partition.window=3600` | 有 | 保持不变，建议手动触发 OPTIMIZE |
+| 配置合理 | 无 | 无需优化 |
+
+---
+
+## Compaction 策略说明
+
+| 模式 | 配置值 | 含义 |
+|-----|-------|------|
+| DML | `cz.compaction.strategy=dml` | DML 触发，间隔由 `min.interval` 控制 |
+| Background | `cz.compaction.strategy=background` | 后台自动，忽略窗口由 `ignore.latest.partition.window` 控制 |
+| DML+Background | `cz.compaction.strategy=dml\|background` | 同时启用 |
+
+**默认**：未配置时使用 Background 模式。
+
+---
+
+## 注意事项
+
+1. **所有 SQL 必须由脚本生成** - 禁止自己编写
+2. **ALTER TABLE 需用户确认** - 不要自动执行
+3. **手动触发 Compaction 只能建议** - 命令是 `OPTIMIZE schema.table_name`，不要自动执行
+4. **表名格式** - 必须使用 `schema.table` 两段式命名
+5. **小文件判断标准** - 参考值（非硬性阈值）：平均文件大小 ~768MB，文件数量 ~10，接近标准也可接受
+6. **参数配置智能化** - 必须先获取当前配置，根据现有值决定新配置：
+   - 无配置 → 使用默认值
+   - 有配置但需调整 → 在当前值基础上调小
+   - 配置已经很小 → 保持不变，建议手动 OPTIMIZE

+Step 1: 收集错误信息（调用工具）
+    ↓
+Step 2: 错误分类
+    ↓
+Step 3: 执行对应诊断策略
+    ↓
+Step 4: 生成解决方案
+    ↓
+Step 5: 输出诊断报告
+```
+
+---
+
+## Step 1: 收集错误信息
+
+### 1.1 基础信息收集（必须）
+
+```
+1. 调用 get_task_detail(task_id) 获取任务基本信息（非必需步骤）
+   → 确定任务类型：SQL / Shell / Python / 多表实时同步 / 离线同步 
+
+2. 调用 get_task_instance_detail(instance_id) 获取实例详情
+   → 获取实例状态、开始时间、结束时间、错误码
+
+3. 调用 get_execution_log(instance_id) 获取执行日志
+   → 获取详细错误信息和堆栈
+```
+
+### 1.2 扩展信息收集（按需）
+
+| 场景 | 需要调用的工具 |
+|------|---------------|
+| 疑似依赖问题 | `get_task_run_dependencies(instance_id)` |
+| 需要分析历史 | `list_task_run(task_id)` |
+| 检查配置问题 | `get_task_configuration_detail(task_id)` |
+| 分析运行趋势 | `get_task_run_stats(task_id)` |
+
+---
+
+## Step 2: 错误分类
+
+根据错误信息的特征，将错误分为以下类别：
+
+### 2.1 数据集成错误 (INTEGRATION)
+
+**识别特征**：任务类型为数据同步/数据集成
+
+| 子类型 | 特征关键字 |
+|--------|-----------|
+| 源端错误 (SOURCE) | `connection failed`, `source permission denied`, `source table not found` |
+| 传输错误 (TRANSFER) | `network error`, `transfer timeout`, `channel error` |
+| 目标端错误 (TARGET) | `write failed`, `target conflict`, `target permission denied` |
+
+### 2.2 SQL 执行错误 (SQL)
+
+**识别特征**：任务类型为 SQL 任务，或错误信息包含 SQL 相关内容
+
+| 子类型 | 特征关键字 |
+|--------|-----------|
+| 语法错误 (SYNTAX) | `syntax error`, `unexpected token`, `parse error` |
+| 语义错误 (SEMANTIC) | `table not found`, `column not found`, `type mismatch`, `ambiguous` |
+| 资源错误 (RESOURCE) | `stage`, `out of memory`, `partition too large`, `slot` |
+| 权限错误 (PERMISSION) | `permission denied`, `access denied`, `unauthorized` |
+
+### 2.3 调度错误 (SCHEDULING)
+
+**识别特征**：任务未开始执行，或与调度相关
+
+| 子类型 | 特征关键字 |
+|--------|-----------|
+| 依赖错误 (DEPENDENCY) | `waiting for upstream`, `dependency failed`, `upstream timeout` |
+| 配置错误 (CONFIG) | `kill`, `timeout exceeded`, `parameter error`, `cron invalid` |
+| 资源错误 (RESOURCE) | `vc unavailable`, `queue full`, `resource exhausted`, `no available slot` |
+
+### 2.4 数据质量错误 (DATA_QUALITY)
+
+**识别特征**：任务类型为 DQC，或错误信息包含质量校验相关内容
+
+| 子类型 | 特征关键字 |
+|--------|-----------|
+| 数量异常 (QUANTITY) | `row count`, `empty result`, `count mismatch` |
+| 内容异常 (CONTENT) | `duplicate`, `null value`, `format error` |
+| 一致性异常 (CONSISTENCY) | `mismatch`, `inconsistent`, `checksum failed` |
+
+### 2.5 其他错误 (OTHER)
+
+如果无法匹配以上任何类别，归类为 OTHER，需要进一步分析。
+
+---
+
+## Step 3: 执行对应诊断策略
+
+### 3.1 数据集成错误诊断
+
+```
+1. 调用 get_task_detail 确定集成类型（离线同步 / 实时同步）
+2. 调用 get_execution_log 获取详细错误
+3. 根据子类型定位问题端：
+   - SOURCE: 检查源端连接、权限、表是否存在
+   - TRANSFER: 检查网络状态、传输配置
+   - TARGET: 检查目标端权限、冲突处理策略
+   - dataType：字段类型错误，可直接给出结论：直接提示字段错误查看目标表的字段是否正确。
+4. 调用 get_task_configuration_detail 检查配置
+5. 生成针对性解决方案
+```
+
+### 3.2 SQL 执行错误诊断
+
+```
+1. 调用 get_execution_log 获取完整错误日志
+2. 判断错误子类型：
+   - SYNTAX/SEMANTIC: 
+     * 分析 SQL 语句，定位具体错误位置
+     * 参考 reference/error_patterns.yaml 中的模式
+   - RESOURCE: 
+     * 如果包含 "stage" 关键字，需要分析 job history
+     * 调用 get_task_run_stats 分析资源使用趋势
+   - PERMISSION: 
+     * 检查用户权限配置
+3. 生成 SQL 修改建议或资源优化建议
+```
+
+### 3.3 调度错误诊断
+
+```
+1. 根据子类型执行诊断：
+   - DEPENDENCY: 
+     * 调用 get_task_run_dependencies 获取依赖关系
+     * 逐个检查上游任务状态
+     * 找到失败的根因任务
+   - CONFIG:
+     * 调用 get_task_configuration_detail 检查任务配置
+     * 检查超时设置、cron 表达式
+   - RESOURCE:
+     * 检查 VC 状态和队列排队情况
+2. 调用 list_task_run 查看历史，判断是否偶发
+3. 生成解决方案
+```
+
+### 3.4 数据质量错误诊断
+
+```
+1. 调用 get_task_detail 获取 DQC 规则配置
+2. 调用 get_execution_log 获取校验结果详情
+3. 分析失败原因：
+   - 规则配置是否合理
+   - 数据本身是否有问题
+4. 生成修复建议
+```
+
+---
+
+## Step 4: 生成解决方案
+
+根据诊断结果，从以下维度生成解决方案：
+
+### 解决方案结构
+
+```
+标题: [简明描述问题和解决方向]
+根因: [一句话说明根本原因]
+步骤:
+  1. [具体操作步骤1]
+  2. [具体操作步骤2]
+  ...
+预期效果: [执行后的预期结果]
+注意事项: [可选，需要特别注意的点]
+```
+
+### 常见解决方案
+
+参考 `reference/solutions.yaml` 获取预定义的解决方案模板。
+
+---
+
+## Step 5: 输出诊断报告
+
+### 报告格式
+
+```markdown
+## 诊断报告
+
+**任务信息**
+- 任务ID: {task_id}
+- 实例ID: {instance_id}
+- 任务类型: {task_type}
+
+**错误分类**
+- 类别: {category}
+- 子类型: {error_type}
+
+**根因分析**
+{root_cause_description}
+
+**解决方案**
+{solution}
+
+**诊断路径**
+{diagnosis_steps}
+```
+
+---
+
+## 注意事项
+
+1. **信息脱敏**：输出时不要暴露敏感信息（密码、token、内部 IP 等）
+2. **降级处理**：如果某个工具调用失败，基于已有信息继续诊断
+3. **兜底方案**：如果无法确定错误类型，提供通用排查建议
+4. **追问确认**：信息不足时，主动向用户询问 task_id 或 instance_id

+# 诊断案例库
+
+真实案例及其诊断思路，供 AI Agent 参考学习。
+
+---
+
+## 案例 1: 作业超时 - SDK killed
+
+### 错误现象
+
+```
+Clickzetta sql job: xxx
+Timeout after 300.0seconds, killed by sdk
+```
+
+**关键字**: `timeout`, `killed by sdk`, `300.0seconds`
+
+**分类**: SQL > 资源错误 (RESOURCE)
+
+---
+
+### 诊断思路
+
+```
+Step 1: 为什么超时？
+    │
+    ├─→ 检查资源是否够用（整体以及 VC 都看下）
+    │
+    ├─ 资源不够用 → 先加资源，然后到 Step 2
+    │
+    └─ 资源够用 → 到 Step 2
+
+Step 2: 这个作业应该跑多久？5分钟是个合理超时时间还是不是？
+    │
+    ├─→ 调用 get_task_run_stats 查看历史运行时间平均值
+    │
+    ├─ 5分钟不合理（SQL本身就慢）→ 看 SQL 为什么跑得慢，优化 SQL
+    │
+    └─ 5分钟合理 → 到 Step 3
+
+Step 3: 5分钟超时哪儿来的？
+    │
+    ├─→ 执行 desc vcluster 看看 VC 上配了没
+    │
+    └─→ 也可能来自很老的 Python connector，用文档里的方法把超时时间加大
+```
+
+---
+
+### 解决方案
+
+**根因**: Python SDK 默认超时时间（300秒）不足以完成作业
+
+**步骤**:
+1. 检查 VC 资源配置：执行 `desc vcluster` 查看超时配置
+2. 检查 Python connector 版本，确认是否使用了旧版本
+3. 在代码中设置作业运行超时时间
+
+**代码示例**:
+
+```python
+# 设置作业运行超时时间为 30 秒（或更长，根据实际需要调整）
+my_param = {
+    'hints': {
+        'sdk.job.timeout': 30
+    }
+}
+
+cursor.execute('YOUR_SQL_QUERY', parameters=my_param)
+```
+
+**参考文档**: https://yunqi.tech/documents/python_reference/connector
+
+---
+
+### 关键点
+
+- 超时可能来自 VC 配置或 SDK 配置
+- 先排查资源问题，再看超时配置
+- 历史运行时间是判断超时是否合理的重要依据
+- 老版本 Python connector 可能有默认超时限制

+⚠️ MANDATORY: Whenever the question requires any domain-specific knowledge beyond common sense or simple recall, you MUST strictly follow this workflow:
+
+<step number="1" priority="CRITICAL">
+<name>Search for Relevant Skills whenever the question requires any domain-specific knowledge beyond common sense or simple recall</name>
+<action>Immediately call the find_helpful_skills tool</action>
+<when>
+- First step for ANY user request
+- Regardless of task complexity or your confidence level
+- BEFORE executing any searches, coding, or other operations
+</when>
+<output>Retrieve best practices and step-by-step guidance from the verified skills library</output>
+</step>
+
+<step number="2" priority="HIGH">
+<name>Evaluate Skills Results and EXECUTE</name>
+<condition_a>
+<if>Relevant skills found</if>
+<then>
+When a user asks about the available skills, list_skills must be invoked.
+⚠️ CRITICAL: You MUST EXECUTE the skills if they contain scripts, commands, or step-by-step instructions
+
+<execution_protocol>
+1. READ the skill instructions carefully, especially sections marked "AI EXECUTION INSTRUCTIONS"
+2. EXECUTE the commands/tools specified in the skill (e.g., cz-table-stats, cz-sql-history)
+3. PARSE the output and extract SQL queries, python scripts or other results
+4. EXECUTE any generated SQL queries using the appropriate MCP tools (e.g., LH-execute_read_query)
+
+❌ DO NOT:
+- Just explain what the skill does without executing it
+- Show the user the skill documentation content
+- Skip the execution steps and provide generic advice
+

+
+### 1. 获取 Semantic View 定义
+使用 \`desc_semantic_view\` 获取当前定义，查看：
+- 已有的 TABLES（逻辑表）
+- 已有的 DIMENSIONS（已添加的维度）
+- 可用的表字段
+
+### 2. 分析用户需求
+从用户描述中提取：
+- 需要添加的维度类型（日期、地区、类别等）
+- 相关的业务实体（订单、客户、商品等）
+- 维度的用途
+
+### 3. 选择维度
+从 TABLES 中选择合适的字段作为维度：
+- 字段必须来自已定义的逻辑表
+- 避免重复（检查已有 DIMENSIONS）
+- 考虑字段的业务含义
+
+### 4. 输出 JSON
+返回要添加的维度列表：

Subject: [PATCH 071/521] feat(mcp-server): port ClickzettaMCPServer +
 ToolConfig (mcp_server.py)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- mcp_server.py:990-1059 ToolConfig → ToolConfig class
- mcp_server.py:41-80    ClickzettaMCPServer.__init__ → ClickzettaMcpServer constructor
- mcp_server.py:157-183  _initialize_config_params → _initializeConfigParams
- mcp_server.py:185-198  _get_service_url → _getServiceUrl
- mcp_server.py:407-433  _resolve_config_from_user_config → _resolveConfigFromUserConfig
- mcp_server.py:511-539  _get_config_value → _getConfigValue
- mcp_server.py:624-676  infer_region_from_host → ClickzettaMcpServer.inferRegionFromHost (static)
- mcp_server.py:644-676  extract_auth → ClickzettaMcpServer.extractAuth (static)
- server_core.py:475-522 update_connection_config → McpServerCore.updateConnectionConfig

Methods requiring external service calls (_updateServerConnection, initialize, run,
_authenticateUser, _loadUserConfig, _resolveInstanceInfo, _resolveConfigWithPriority,
_registerHttpHandlers) are ported as documented stubs.

 wire tools/resources/prompts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- mcp_registrar.py:36-57   MCPComponentRegistrar.__init__ → McpComponentRegistrar constructor
- mcp_registrar.py:200-230 register_tools_to_server → registerToolsToServer
- mcp_registrar.py:232-254 register_resources_to_server → registerResourcesToServer (delegates to registerResources)
- mcp_registrar.py:256-278 register_prompts_to_server → registerPromptsToServer (delegates to registerPrompts)
- mcp_registrar.py:575-605 _execute_tool_for_server → _executeToolForServer (private)
- mcp_registrar.py:538-573 _execute_tool_direct → _executeToolDirect (private)
- mcp_registrar.py:897-920 _format_result_safe → _formatResultSafe (private)
- mcp_registrar.py:922-941 _format_error_safe → _formatErrorSafe (private)
- mcp_registrar.py:820-853 _get_prompts_list_for_server → list_prompts handler in registerPrompts()
- mcp_registrar.py:855-895 _get_prompt_for_server → get_prompt handler in registerPrompts()
- prompts/__init__.py:11-16 PROMPTS registry → PROMPTS export in prompts/index.ts

Also adds registerPrompts() + PROMPTS registry to prompts/index.ts, and
wires McpComponentRegistrar.registerAll() into run-stdio.ts and run-http.ts.

Tests: 64 pass, 0 fail
Smoke test: initialize → capabilities {tools:{}, resources:{}, prompts:{}}

Subject: [PATCH 075/521] feat(mcp-server): port skills update_checker +
 http_server
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- update_checker.py:18-37   → skills/update-checker.ts UpdateResult interface
- update_checker.py:39-239  → skills/update-checker.ts GitHubSourceTracker class
- update_checker.py:241-342 → skills/update-checker.ts LocalSourceTracker class
- update_checker.py:344-416 → skills/update-checker.ts UpdateChecker class
- http_server.py:31-64      → skills/http-server.ts LoadingState class
- http_server.py:66-136     → skills/http-server.ts registerMcpTools()
- http_server.py:138-185    → skills/http-server.ts buildHealthResponse()
- http_server.py:188-319    → skills/http-server.ts initializeBackend()
- http_server.py:322-348    → skills/http-server.ts runServer()

Framework divergences: FastMCP+uvicorn → MCP SDK Server+Hono+node:http;
threading.Thread → Promise; @mcp.tool() → setRequestHandler().
Also adds skills/index.ts barrel.

Subject: [PATCH 077/521] feat(mcp-server): port SkillsMCPServer
 (mcp_handlers.py)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python → TS mapping:
- mcp_handlers.py:17-93   LoadingState → LoadingState (re-exported from http-server.ts)
- mcp_handlers.py:94-577  SkillsMCPServer → SkillsMcpServer
- mcp_handlers.py:578-668 handle_search_skills → handleSearchSkills
- mcp_handlers.py:669-804 handle_read_skill_document → handleReadSkillDocument
- mcp_handlers.py:805-854 handle_list_skills → handleListSkills

Also adds SkillSearchEngine.getSkills() getter (needed by mcp_handlers.py:378,527)
and exports SkillsMcpServer + standalone handlers from skills/index.ts.

Subject: [PATCH 078/521] feat: remove Python cz-tool dependency, integrate TS
 cz-cli natively
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace subprocess cz-tool invocation with in-process execute() from @clickzetta/cli
- Remove Python binary download from build.ts and Makefile
- Add profiles-llm.ts, config-llm.ts, setup.ts from main branch
- Add --profile flag to agent run (CZ_PROFILE env var)
- Add ClickZetta as first-class LLM provider with model catalog
- Rebrand OPENCODE_ → CLICKZETTA_ (env vars, paths, config dirs)
- Fix poll.ts: add resubmit with new job ID + maxRetries limit
- Fix arrow.ts: add timezone conversion for TIMESTAMP_LTZ
- Fix converter.ts: add czStruct() for STRUCT type support
- Add apilevel export to SDK
- Clean up setup.sh: remove cz-tool install, add legacy cleanup
- Remove forward.ts (no longer needed)

Breaking: Python cz-tool binary is no longer bundled or required.

+# cz-cli TypeScript 全量重写设计
+
+## 背景
+
+当前 cz-agent 项目（opencode fork）通过 `forward.ts` 将 Lakehouse 命令转发给打包的 Python cz-tool 二进制（cz-cli 的 PyInstaller 产物）。这带来体积大、环境脆弱、打包复杂等问题。
+
+本次重写将 cz-cli 的所有逻辑用 TypeScript 重新实现，消除 Python 依赖。
+
+## 核心发现
+
+cz-cli 底层全部是 HTTP REST 调用，无私有协议：
+
+1. **SQL 通路**（clickzetta-connector）：`/lh/submitJob`、`/lh/getJob`、`/lh/cancelJob`
+2. **Studio 通路**（cz-mcp-server）：`/clickzetta-portal/`、`/ide-admin/v1/`、`/ide-authority/v1/` 共 50+ 端点
+3. **AI Agent 通路**：`/ai/api/conversations`、`/ai/api/chat`、`/ai/health`
+
+认证统一使用 `X-Clickzetta-Token` header + JSON body。
+
+## 总体架构

+```
+
+## 包结构
+
+### `packages/clickzetta-sdk`
+
+HTTP client 层，1:1 对齐 Python clickzetta-connector 和 cz-mcp-server 的行为。
+
+```
+packages/clickzetta-sdk/src/
+  index.ts             — 公开 API 入口
+  client.ts            — 统一 HTTP client（重试、超时、错误处理、header 注入）
+  auth/
+    login.ts           — loginSingle（PAT / 用户名密码）
+    token.ts           — token 缓存、过期检测、自动刷新
+    user.ts            — getCurrentUser、getUserConfig
+  sql/
+    submit.ts          — /lh/submitJob
+    poll.ts            — /lh/getJob（轮询结果）
+    cancel.ts          — /lh/cancelJob
+    split.ts           — SQL 拆分（移植 Python utils.split_sql）
+    types.ts           — QueryResult、JobStatus 等类型
+  studio/
+    task.ts            — task CRUD（add、getDetail、save、submit、offline 等）
+    runs.ts            — 任务实例（list、getDetail、stop、rerun、complement）
+    flow.ts            — flow DAG（getDag、createNode、bind、unbind、submit）
+    attempts.ts        — attempt 记录和日志
+    execute.ts         — adhoc 执行
+    folder.ts          — 文件夹管理
+    datasource.ts      — 数据源操作
+    schedule.ts        — 调度任务
+  workspace/
+    workspace.ts       — listUserWorkspaces、切换 workspace
+  agent/
+    chat.ts            — AI Agent 对话（conversations、chat、health）
+  config/
+    region.ts          — 区域检测、base URL 解析
+    connection.ts      — 连接配置解析（JDBC URL、环境变量、profile 优先级）
+  types/
+    index.ts           — 共享类型（ConnectionConfig、StudioConfig、AuthToken 等）
+    api.ts             — API 响应类型（{ code, message, data }）
+```
+
+设计原则：
+- 每个模块只做 HTTP 调用 + 类型转换，不含 CLI 逻辑
+- `client.ts` 统一处理：重试（2 次，指数退避）、token 注入、错误码解析
+- 所有方法返回强类型
+- token 自动刷新（过期因子 0.8，与 Python 版一致）
+
+### `packages/cz-cli`
+
+cz-tool 的实现，对齐 Python cz-cli 的所有命令。CLI 框架使用 yargs（与 opencode 一致）。
+
+```
+packages/cz-cli/src/
+  index.ts             — cz-tool 入口
+  cli.ts               — yargs 命令注册
+  commands/
+    sql.ts             — SQL 执行（安全护栏、异步、变量替换）
+    profile.ts         — profile CRUD + discover + list-workspaces
+    schema.ts          — schema list / describe / create / drop
+    table.ts           — table list / describe / preview / stats / history / create / drop
+    workspace.ts       — workspace current / use
+    task.ts            — task CRUD + flow 子命令组
+    runs.ts            — runs list / detail / wait / logs / deps / stop / stats / refill
+    attempts.ts        — attempts list / log
+    agent.ts           — agent status / ask
+    job.ts             — job 性能分析
+    status.ts          — 版本和连接状态
+    ai-guide.ts        — AI agent 命令参考输出
+    install-skills.ts  — 安装 AI skills 到外部 agent
+  connection/
+    config.ts          — 连接配置解析（优先级链）
+    profile-store.ts   — profiles.toml 读写
+  output/
+    formatter.ts       — 输出格式化（json / pretty / table / csv / jsonl / toon）
+    masking.ts         — 敏感数据脱敏（手机、邮箱、密码、身份证）
+  logger.ts            — 操作日志（sql-history.jsonl）
+  guide-builder.ts     — AI guide 生成
+  version.ts           — 版本号
+```
+
+#### 命令清单
+
+| 命令 | 子命令 | Python 来源 |
+|------|--------|-------------|
+| `sql` | 直接执行，`--write`、`--async`、`-e`、`-f`、`--variable`、`--set`、`--job-profile` | commands/sql.py |
+| `profile` | list、detail、create、update、delete、use、discover、list-workspaces、render-command | commands/profile.py + profile_bootstrap.py |
+| `schema` | list、describe、create、drop | commands/schema.py |
+| `table` | list、describe、preview、stats、history、create、drop | commands/table.py |
+| `workspace` | current、use（`--persist`） | commands/workspace.py |
+| `task` | list、list-folders、create、create-folder、content、save-content、save-config、deps、execute、online、offline | commands/task.py |
+| `task flow` | dag、create-node、remove-node、bind、unbind、node-detail、node-save、node-save-config、submit、instances | commands/task.py |
+| `runs` | list、detail、wait、logs、deps、stop、stats、refill | commands/runs.py |
+| `attempts` | list、log | commands/attempts.py |
+| `agent` | status、ask（`--conversation-id`） | commands/agent.py |
+| `job` | 性能分析（当前 Python 版大部分注释） | commands/job.py |
+| `status` | 显示版本、连接状态 | main.py |
+| `ai-guide` | 输出 AI agent 命令参考（json / toon） | guide_builder.py |
+| `install-skills` | 安装 AI skills 到外部 agent | commands/skills_installer.py |
+
+#### 保留行为
+
+- 全局选项：`--profile`、`--jdbc`、`--pat`、`--output`、`--debug`、`--silent`、`--verbose` 等自动注入
+- 连接配置优先级：CLI 参数 > JDBC URL > 环境变量 > profile > 默认值
+- SQL 安全护栏：`--write` 写保护、无 WHERE 拦截、自动 LIMIT 100、敏感数据脱敏
+- 输出格式：json / pretty / table / csv / jsonl / toon
+- 操作日志：`~/.clickzetta/sql-history.jsonl`
+- Profile 存储：`~/.clickzetta/profiles.toml`
+
+### `packages/opencode` 改动
+
+#### 入口改名
+- 二进制名从 `czagent` 改为 `czcli`（保留别名 `cz`、`cz-cli`、`clickzetta-cli`）
+- 路由逻辑：`agent` 子命令走 opencode，其他转发给 cz-tool
+
+#### 删除的代码
+- `src/installation/index.ts` 中下载安装 Python cz-cli 的逻辑全部删除
+- `src/cli/cmd/forward.ts` 重写，指向新的 TS cz-tool 二进制
+- `src/profile/` 目录删除，profile 逻辑统一到 `packages/cz-cli`
+- `src/cli/cmd/profile.ts` 删除，同上
+
+#### cz-tool 内置 tool
+- 在 `src/tool/` 下新增 `cz-tool.ts`，注册为 opencode 内置 tool
+- 实现：spawn cz-tool 进程执行命令，返回结构化结果
+- agent 在对话中可直接调用（与 bash、read、write 等 tool 并列）
+
+#### 保留不动
+- TUI、session、provider、storage、server、config 等全部不动
+- 配置文件路径不变（`~/.clickzetta/czagent.json`）
+
+#### opencode 直接调 SDK
+- profile 验证连接：从 shell out 改为直接调 `clickzetta-sdk` 的 sql 模块
+
+## 构建与分发
+
+- `packages/clickzetta-sdk` — 纯库，被其他包引用
+- `packages/cz-cli` — Bun 编译为 `cz-tool` 二进制
+- `packages/opencode` — Bun 编译为 `czcli` 二进制，构建时将 cz-tool 打包到产物目录
+- 产物结构：`czcli` + `cz-tool/cz-tool`（与当前结构一致）
+- `setup.sh` 安装时释放两个二进制到正确路径

-# cz-cli Skill
+# cz-cli — ClickZetta Lakehouse Subagent
 
-> [!IMPORTANT]
-> **Fallback**: If `cz-cli` command not present, check for a bundled binary at `scripts/<platform>/cz-cli` (e.g. `scripts/macos-arm64/cz-cli`, `scripts/linux-x86_64/cz-cli`, `scripts/windows-x86_64/cz-cli.exe`). If found, use its absolute path directly. Otherwise run `pip3 install cz-cli -U` then use `cz-cli` from PATH.
+You have no direct Lakehouse access. Always delegate via cz-cli.
 
-## AI Agent Behavior Rules
+## Route to cz-cli
 
-> [!IMPORTANT]
-> Read these rules before invoking any command.
+- SQL against Lakehouse (SELECT, DDL, DML)
+- Studio task development, scheduling, monitoring
+- Table/schema/database management
+- Data pipelines (sync, import, CDC)
+- Profile and connection configuration
+- Performance analysis and optimization
+- Any mention of cz-cli, ClickZetta, or Lakehouse
 
-### Rule 0 — Initialize connection profile before first use
+## Keep in host agent
 
-When any command returns error code `NO_PROFILE`, run `cz-cli setup --credential <base64>` if the credential string is available, or read `references/profile-setup.md` and follow the onboarding steps there. Always use the **AskUserQuestion tool** — never ask via plain text.
+- General programming unrelated to ClickZetta
+- Local file operations, git
+- Non-ClickZetta databases (PostgreSQL, MySQL standalone)
 
-### Rule 1 — Clarify intent before any state-changing operation
-
-When a task involves an operation that changes system state (publishing a schedule, taking a task offline, triggering a run, deleting an object, etc.):
-
-**Do NOT proceed without** explicitly understanding the user's intent on all three points:
-1. **Target**: Which task / table / run instance?
-2. **Purpose**: Why does this need to happen now?
-3. **Side-effect acknowledgment**: Does the user understand the impact (historical re-runs, schedule interruption, permanent deletion, etc.)?
-
-Use the **AskUserQuestion tool** (not plain text) to confirm with the user, then wait for an explicit reply before executing.
-
-Consult **Command Risk Reference** below to determine whether a command qualifies as state-changing.
-
-
-### Rule 2 — Route to companion skill BEFORE acting (MUST)
-
-> [!IMPORTANT]
-> Check this routing table **before** executing any command or writing any code.
-> If the user intent matches a trigger below, **MUST** invoke the listed skill immediately and stop processing in cz-cli.
-
-The following companion skills can be installed alongside `cz-cli` via `cz-cli install-skills`:
-
-- **lakehouse-python-sdk** — Lakehouse Python/Shell task engineering: develop, rewrite, optimize, troubleshoot. Covers connector, BulkLoad, IGS, Studio params, datasource, and CREATE TABLE DDL; MUST trigger on: develop/write/create/modify/rewrite/optimize Python or Shell task; BulkLoad batch upload; IGS realtime ingest; connector query/write; Python task error/diagnosis; CREATE TABLE / partition / bucket / index DDL.
-- **lakehouse-doc** — ClickZetta Lakehouse official documentation. Covers SQL syntax, data types, functions, DDL/DML commands, dynamic tables, materialized views, access control, VCluster, data lake, AI functions, etc. When the user writes or asks about SQL syntax or Lakehouse dialect specifics, **MUST** consult lakehouse-doc skill references first to ensure accuracy.
-
-**If no row matches**: proceed with cz-cli commands directly.
-
-### Rule 2.1 — MUST consult lakehouse-doc skill for SQL commands
-
-When the user request involves any of the following, **MUST** consult **lakehouse-doc** skill references before answering or generating SQL:
-
-- Writing, modifying, or optimizing SQL statements (DDL / DML / DQL)
-- Asking about ClickZetta Lakehouse SQL dialect syntax, keywords, or function usage
-- Using data types, type casting, or datetime formats
-- Creating or altering tables, views, materialized views, dynamic tables, external tables
-- Data import/export (COPY INTO, PUT/GET, BulkLoad, Pipe)
-- Access control (GRANT / REVOKE), roles, permissions
-- VCluster configuration and management
-- Index creation and usage (inverted index, BloomFilter, vector index)
-- AI functions, vector search, semantic views
-- Information Schema system view queries
-
-**Rationale**: ClickZetta Lakehouse SQL dialect differs from standard SQL and other databases. Relying on general knowledge may produce incorrect syntax. Consulting lakehouse-doc significantly improves answer accuracy and confidence.
-
-### Rule 3 — Development ends at save; execution requires separate authorization
-
-When the user says "develop", "write", "create", or "modify" a task, the work is **complete once the script is saved successfully**.
-After saving, tell the user: "The task has been saved as a draft. Scheduling is not yet active. Let me know explicitly if you want to publish or execute it."
-
-**Do NOT** auto-publish, auto-trigger execution, or auto-submit a backfill after saving — even if those steps seem like the logical next thing. Every phase that produces a real side effect requires the user to express intent and grant authorization separately.
-
-**Exception**: If the user's original request *explicitly* authorized all subsequent steps (e.g. "create and immediately go live", "develop and run it now"), AND Rule 1 already confirmed that intent at the start, the Agent may proceed through the authorized steps without stopping again at each phase. Do not re-ask for confirmation that was already given.
-
-### Rule 4 — Paginated results are not complete data
-
-All `list` commands return only page 1 by default (typically 10 items). The `ai_message` field in the response contains the total count and the command to fetch the next page — treat it as the authoritative next-step hint and follow it. Never treat a first-page result as the full dataset.
-
-**Pagination termination rules**:
-- If the user only needs "latest / recent N items": stop after page 1, do not paginate.
-- If the user needs the full dataset: paginate until `ai_message` no longer contains a next-page hint.
-- **Safety limit**: auto-paginate at most **3 pages** (≈ 30 items). If more exist, surface the next-page command to the user and ask whether to continue.
-
-### Rule 5 — Always pass explicit task type when creating tasks
-
-When creating a task with `cz-cli task create`, **always** pass `--type` explicitly (`SQL` / `PYTHON` / `SHELL` / `SPARK` / `FLOW`).
-The Python SDK(connector/igs/bulkload) is using from clickzetta import connect instead of Zettapark's session.
-
-- **MUST NOT** rely on default task type.
-- If user intent says “Python task”, command must include `--type PYTHON`.
-- If `--type FLOW`, immediately switch to Rule 6 — use Flow-specific commands exclusively.
-
-### Rule 6 — Flow nodes use Flow-specific tools exclusively
-
-When the operation target is a Flow task or any of its child nodes (`task_type=500`, or user mentions "composite task / flow / workflow"):
-
-- **MUST** use Flow-specific commands: `task flow node-detail`, `task flow node-save`, `task flow node-save-config`, `task flow bind`, `task flow submit`, etc.
-- **MUST NOT** use `task save`, `task save-config`, `task detail`, or `task online` on Flow child nodes — these tools are for regular (non-Flow) tasks only and will produce incorrect results or errors.
-- **Decision rule**: if `task_type == 500` OR the user mentions flow/workflow context → use `task flow *` commands unconditionally.
-
-### Rule 7 — Always display studio_url in final report
-
-Responses from `task`, `runs`, and `executions` commands may include a `studio_url` field. When present, surface it in the end to the user so they can open the resource directly in Studio.
-
-Display as a Markdown hyperlink: `[View in Studio](https://...)`. Show all studio_url values returned across all commands in the same response — do not deduplicate.
-
-### Rule 8 — Maximize execution efficiency: parallel and chained commands
-
-**Independent commands → parallel.  Dependent commands → chain with `--field`.**
+## Execution
 
 ```bash
-# Async SQL: submit → poll → fetch result → preview first rows
-JOB=$(cz-cli sql "SELECT * FROM orders LIMIT 100" --field job_id) && cz-cli job status $JOB -o toon && cz-cli job result $JOB -o toon | head -12
-
-# Parallel: two independent lookups at the same time
-cz-cli task content my_task -o toon & cz-cli runs list --task my_task -o toon & wait
-
-# Chain: save then verify
-cz-cli task save-content my_task --file script.sql && cz-cli task content my_task -o toon
+cz-cli agent run "<request>" --format a2a --dangerously-skip-permissions
 ```
 
-Key tools:
-- `--field <name>` — extract one value as raw text: `cz-cli sql "..." --field job_id` → `2026042818122957849079780`
-- `-o toon` — line-per-field output, works with `grep`/`head`
-- `-o json` — single-line JSON, parse in code only (do NOT pipe to grep/head)
-
-**Shortcut**: Use `cz-cli sql --sync "..." > /tmp/res.json` to force synchronous execution (waits for results inline). Prefer `--sync` for simple/fast queries.
-
-## Command Quick Reference
-
-### Connection & Profile
-- `cz-cli profile create <name> --username U --password P --instance I --workspace W` — Create profile
-- `cz-cli profile create <name> --pat TOKEN --instance I --workspace W` — Create profile with PAT
-- `cz-cli profile list` — List all profiles
-- `cz-cli profile status` — Test connection, show workspace/schema
-- `cz-cli profile use <name>` — Set default profile
-- `cz-cli profile delete <name>` — Delete a profile
-- `cz-cli profile discover --studio-url URL --username U --password P` — Discover regions/instances
-
-### SQL Execution
-- `cz-cli sql "SELECT * FROM t LIMIT 10"` — Execute SQL query
-- `cz-cli sql -f query.sql` — Execute SQL from file
-- `cz-cli sql --write "INSERT INTO t VALUES (...)"` — Write operation (requires --write)

-- `cz-cli sql --sync "SELECT 1"` — Force synchronous execution
-- `cz-cli sql -e "SELECT * FROM t WHERE id = %(id)s" --variable id=123` — Variable substitution
-
-### Job Management (async SQL results)
-- `cz-cli job status <job_id>` — Check job status
-- `cz-cli job result <job_id>` — Fetch result set (waits if running, limited to 100 rows)
-- `cz-cli job result --no-limit <job_id>` — Fetch full result set
-
-### Schema & Table

-description: Routes coding and software development tasks to czcode AI assistant. Use when user asks to write, debug, refactor, or explain code; develop Python/Shell Studio tasks; review code; or asks general programming questions. Do NOT use for SQL execution on Lakehouse, task scheduling, table/schema management, or profile configuration -- those stay with cz-cli.

-# czcode Skill
-
-## Install
-
-```bash
-# Install czcode
-# Download from releases or build from source: ~/code/cz-code
-# Verify installation
-which czcode && czcode --version
-
-# Prerequisite: set your API key
-export ANTHROPIC_API_KEY=your_key_here
-# Or configure in ~/.clickzetta/czcode.json
-
-# Install this skill via cz-cli
-cz-cli install-skills
-```
-
-This skill enables your coding agent to delegate software development tasks to czcode -- ClickZetta's AI coding assistant -- running headlessly in the background, with full security controls and audit logging.
-
-## Architecture Overview
-
-**Routing Principle**: Coding and development tasks -> czcode. Lakehouse operations -> cz-cli.
-
-**Key Components**:
-- `scripts/route_request.py` -- LLM-based semantic routing with credential blocking
-- `scripts/execute_czcode.py` -- Headless czcode execution with NDJSON stream parsing and heartbeat
-- `scripts/security_wrapper.py` -- Full security orchestration (approval, audit, sanitization)
-- `scripts/read_czcode_sessions.py` -- Recent session context enrichment
-- `security/` -- Approval handler, audit logger, cache manager, config manager, prompt sanitizer
-
-**Security Modes**:
-- `prompt` (default): User approves predicted tools before execution
-- `auto`: Auto-approve with mandatory audit logging
-- `envelope_only`: Auto-approve, rely on envelope blocklist only
-
-> **IMPORTANT -- `config.yaml` is optional.** If absent, safe defaults apply (`approval_mode: prompt`). Do NOT search for `config.yaml` before executing -- `ConfigManager` handles this internally.
-
-## Fast Path for Repeat Queries
-
-**Session state is cached -- skip re-initialization on follow-up queries.**
-
-For a follow-up coding request in the same session:
-1. Skip context re-fetch (reuse Lakehouse context from first query)
-2. Call `execute_czcode.py` directly with the enriched prompt
-3. Return results
-
-## Session Initialization
-
-When this skill is first loaded in a session:
-
-### Step 1: Load Routing Context
-```bash
-PYTHON=$(command -v python3 2>/dev/null || echo python3)
-$PYTHON scripts/route_request.py --prompt "test" --dry-run 2>/dev/null || true
-```
-This warms up the config and cache. Skip on follow-up queries.
-
-## Workflow: Handling User Requests
-
-### Step 1: Route the Request
-
-```bash
-PYTHON=$(command -v python3 2>/dev/null || echo python3)
-$PYTHON scripts/route_request.py --prompt "USER_PROMPT_HERE"
-```
-
-**Route to czcode** if request involves:
-- Writing, creating, or modifying code (Python, SQL scripts, Shell, etc.)
-- Debugging, fixing errors, or diagnosing code issues
-- Refactoring or optimizing existing code
-- Explaining or reviewing code
-- Developing Studio task bodies (Python/Shell)
-- General programming questions or best practices
-- User explicitly mentions "czcode"
-
-**Handle locally with cz-cli** if request involves:
-- Executing SQL on ClickZetta Lakehouse (`cz-cli sql`)
-- Managing Studio tasks (create, schedule, online/offline)
-- Table or schema operations
-- Profile/connection configuration
-- Checking run status or execution logs
-
-If routing returns `cz_cli`: handle with cz-cli commands directly. Stop here.
-
-### Step 2: Enrich Context
-
-Build an enriched prompt with Lakehouse context and recent session history:
-
-**Lakehouse Context** (if a cz-cli profile is active):
-```bash
-cz-cli profile list -o json 2>/dev/null | python3 -c "
-import sys, json
-profiles = json.load(sys.stdin).get('data', [])
-if profiles:
-    p = profiles[0]
-    print(f'ClickZetta Lakehouse: instance={p.get(\"instance\",\"\")}, workspace={p.get(\"workspace\",\"\")}, schema={p.get(\"schema\",\"\")}')" 2>/dev/null
-```
-
-**Recent czcode Session Context** (optional, for follow-up tasks):
-```bash
-PYTHON=$(command -v python3 2>/dev/null || echo python3)
-$PYTHON scripts/read_czcode_sessions.py --limit 2
-```
-
-**Enriched Prompt Format**:
-```
-# Lakehouse Context
-[Connection info if relevant to the task]
-
-# Recent czcode Work
-[Summary from recent czcode sessions, if relevant]
-
-# User Request
-[Original user prompt]
-```
-
-### Step 3: Handle Security Approval
-
-```bash
-PYTHON=$(command -v python3 2>/dev/null || echo python3)
-$PYTHON scripts/security_wrapper.py \
-  --prompt "ENRICHED_PROMPT" \
-  --envelope "RW"
-```
-
-- If `status: awaiting_approval` -> show `approval_prompt` to user, wait for response
-- If `status: routed_to_cz_cli` -> handle with cz-cli directly
-- If `status: blocked` -> inform user, do not proceed
-- If `status: executed` or `approval_mode: auto/envelope_only` -> proceed to Step 4
-
-### Step 4: Execute czcode Headlessly
-
-```bash
-PYTHON=$(command -v python3 2>/dev/null || echo python3)
-$PYTHON scripts/execute_czcode.py \
-  --prompt "ENRICHED_PROMPT" \
-  --envelope "RW" \
-  --approval-mode auto
-```
-
-With Lakehouse context injection:
-```bash
-$PYTHON scripts/execute_czcode.py \
-  --prompt "ENRICHED_PROMPT" \
-  --envelope "RW" \
-  --approval-mode auto \
-  --system-prompt "ClickZetta Lakehouse: instance=INSTANCE, workspace=WORKSPACE, schema=SCHEMA"
-```
-
-**Key flags**:
-- `--permission-mode bypass` is set internally -- headless auto-approval
-- `--output-format stream-json` -- NDJSON event stream, parsed in real-time
-- Heartbeat thread prevents AI tool timeouts during long-running tasks
-
-**Security Envelopes**:
-- **RO**: Blocks Edit, Write, destructive Bash -- for read-only tasks
-- **RW**: Blocks only destructive ops (rm -rf, sudo rm) -- for most coding tasks
-- **RESEARCH**: Read + web access, blocks writes -- for exploratory work
-- **DEPLOY**: Full access -- use cautiously, requires confirmation
-
-### Step 5: Return Results
-
-- Display czcode's text output to the user
-- Report any files created or modified
-- If czcode wrote code to be saved as a Studio task: suggest `cz-cli task save`
-
-## Examples
-
-### Example 1: Develop a Python Studio Task
-**User says**: "Write a Python task that reads from table `orders` and writes aggregated results to `orders_summary`"
-
-**Routing**: -> czcode
-
-**Execute**:
-```bash
-$PYTHON scripts/execute_czcode.py \
-  --prompt "Write a Python task that reads from ClickZetta table 'orders' and writes aggregated results to 'orders_summary'. Use the clickzetta connector." \
-  --envelope "RW" \
-  --system-prompt "ClickZetta Lakehouse: instance=my-instance, workspace=default, schema=public"
-```
-
-**Result**: Python task code returned -> save via `cz-cli task save`.
-
-### Example 2: Debug a Failing Task
-**User says**: "My Python task is throwing a KeyError on line 42"
-
-**Routing**: -> czcode (debugging)
-
-**Envelope**: RO (read-only -- just diagnosing)
-
-### Example 3: Execute SQL on Lakehouse
-**User says**: "Run `SELECT COUNT(*) FROM orders`"
-
-**Routing**: -> cz-cli
-
-```bash
-cz-cli sql "SELECT COUNT(*) FROM orders"
-```
-
-No czcode involvement.
-
-### Example 4: Code Review
-**User says**: "Review this Python script for bugs"
-
-**Routing**: -> czcode
-
-**Envelope**: RO (read-only review)
-
-## Troubleshooting
-
-### Error: "czcode: command not found"
-```bash
-which czcode || ls ~/.local/bin/czcode
-# Fallback: use absolute path
-~/.local/bin/czcode --print "..." --permission-mode bypass
-```
-
-### Error: "ANTHROPIC_API_KEY not set"
-```bash
-export ANTHROPIC_API_KEY=your_key_here
-# Or check: cat ~/.clickzetta/czcode.json
-```
-
-### Issue: czcode hangs without output
-**Cause**: Not using `--print` flag in non-TTY environment.
-**Solution**: Always use `execute_czcode.py` -- never invoke `czcode` directly without `--print`.
-
-### Issue: Approval prompts not appearing
-```bash
-# Check approval mode
-cat "$(dirname $(which czcode))/../skills/czcode/config.yaml" 2>/dev/null | grep approval_mode
-# Default is "prompt" -- shows approval prompts
-```
-
-### Issue: Audit log not created
-```bash
-# Ensure log directory exists
-mkdir -p ~/.cache/czcode-skill
-chmod 700 ~/.cache/czcode-skill
-```
-
-### Issue: Output too verbose
-Use `--output-format text` in `execute_czcode.py` for plain text when stream parsing isn't needed.
-
-## Configuration
-
-Copy `config.yaml.example` to `config.yaml` in the skill's install directory to customize:
-- `approval_mode`: prompt / auto / envelope_only
-- `audit_log_path`: where to write audit logs
-- `sanitize_conversation_history`: enable/disable PII removal
-- `credential_file_allowlist`: paths that block routing when mentioned in prompts
-

Subject: [PATCH 079/521] feat: restore forward commands, flatten agent/llm
 CLI, AI-friendly errors

- Add forward.ts: port all 12 cz-tool forwarding commands (sql, table,
  profile, status, ai-guide, install-skills, etc.) missing from TS rewrite
- Restore forward routing in index.ts: non-agent commands go to cz-tool
- Flatten CLI: remove AgentCommand wrapper, register create/list/llm
  directly so all commands are cz-cli agent <cmd> (no double agent)
- Add --format a2a support to run.ts with proper error handling
- Add SetupCommand to yargs so setup --help works correctly
- Restore CZ_* env var expansion in run.ts when --profile is used
- Improve NO_PROFILE error: 3 context-specific JSON variants with next_steps
- Add LLM config epilogue to --help output
- Update skills/cz-cli/SKILL.md and profile-setup.md to match actual commands

-The recommended first-time onboarding entry point is `cz-cli setup`:
+The recommended first-time onboarding entry point:
 
 ```
 cz-cli setup --credential "<base64_string>"
 ```
 
-Or without `--credential` in an interactive terminal to launch the guided flow:
+Or interactive (TTY only):
 
 ```
 cz-cli setup
 ```
 
-The main CLI process **does not** automatically launch an interactive quickstart flow.
-Instead, when no profile exists, data commands (e.g. `sql`, `table list`) output a
-structured `NO_PROFILE` error and exit. The AI agent should then guide the user to
-run `cz-cli setup`.
+For AI agents (non-TTY), always pass `--credential`. Without it, the command outputs JSON with registration URLs and exits 1.
 
-## Non-Interactive / Scripted Setup
+## What setup does
 
-For AI agents or automation (non-TTY environments), always pass `--credential`:
+Writes two files:
+- `~/.clickzetta/profiles.toml` — connection profile (`[profiles.default]`)
+- `~/.local/share/clickzetta/auth.json` — API key
 
+## Profile management
+
+List profiles (forwarded to cz-tool):
 ```
-cz-cli setup --credential "<base64_string>"
+cz-cli profile list
 ```
 
-Or use the equivalent `profile quickstart` subcommand (backward compatible):
+All `cz-cli profile *` subcommands are forwarded to the `cz-tool` binary at `~/.clickzetta/cz-tool/cz-tool`.
 
-```
-cz-cli profile quickstart --credential "<base64_string>"
-```
+## LLM configuration
 
-Without `--credential`, both commands output registration URLs as JSON:
+After setup, the ClickZetta built-in LLM is used by default. To use a different LLM:
 
-```
-cz-cli setup
-cz-cli profile quickstart
-```
+```bash
+# Add and select Claude
+cz-cli agent llm add my-claude --provider anthropic --api-key sk-ant-... --use
+
+# Add OpenAI
+cz-cli agent llm add my-openai --provider openai --api-key sk-...
+
+# Check what's active
+cz-cli agent llm show
 
-## Alternative: Choose auth method (advanced)
-
-If the user prefers manual setup, use the **AskUserQuestion tool**. Present three options:
-
-## Step 2 — Collect credentials (branch by choice)
-
-### Branch A — JDBC URL (user already has one)
-
-1. Ask: "Please paste your JDBC URL (format: `jdbc:clickzetta://...`)."
-2. If the URL contains the literal placeholder `<password>`, ask for the real password separately and substitute it before use.
-3. Derive a profile name from the URL (e.g. `default`) or ask the user.
-4. Run:
-   ```
-   cz-cli profile create <name> --jdbc "<url_with_real_password>"
-   ```
-
-### Branch A — JDBC URL (guided copy-from-Studio flow)
-
-If the user doesn't have a JDBC URL, guide them to copy one from Studio:
-
-1. Ask: "What is your Studio page URL?"
-2. Do not ask user to identify URL type. Accept any Studio URL directly.
-   Examples:
-   - `https://rwyaytab.accounts.clickzetta.com/accountManage/accountInfo`
-   - `https://czstudio.devops.xiaohongshu.com/accounts/wuhsuxis/login`
-   - `https://studio-bj-gaotu.clickzetta-inc.com/app/14743d05`
-3. Reply with the exact link to open:
-   ```
-   <studio_url>/management/environment
-   ```
-   Then prompt: "Navigate to **工作空间 → 连接配置 → 复制**. This copies a JDBC URL that may contain `<password>` as a placeholder."
-4. Ask the user to paste the copied URL, then handle the `<password>` placeholder as above.
-
-### Branch B — PAT
-
-1. Ask for: PAT value, instance name, workspace name (optionally: default schema, vcluster).
-2. Run:
-   ```
-   cz-cli profile create <name> --pat <PAT> --instance <instance name> --workspace <WS>
-   ```
-
-### Branch C — Username / Password (recommended discovery flow)
-
-1. Ask for:
-   - username
-   - password
-   - Studio page URL
-2. Run the built-in discover command to authenticate and discover regions + instances:
-   ```
-   cz-cli profile discover \
-     --studio-url "<studio_url>" \
-     --username "<username>" \
-     --password "<password>"
-   ```
-   The command auto-detects URL type; user does not need to distinguish account URL vs app URL.
-3. Ask user to choose region, then list workspaces in that region:
-   ```
-   cz-cli profile list-workspaces \
-     --studio-url "<studio_url>" \
-     --username "<username>" \
-     --password "<password>" \
-     --region "<region_id_or_alias>" \
-     --instance "<optional_instance_name>"
-   ```
-4. Generate a safe `profile create` command (default schema/vcluster included):
-   ```
-   cz-cli profile render-command \
-     --studio-url "<studio_url>" \
-     --username "<username>" \
-     --password "<password>" \
-     --region "<region_id_or_alias>" \
-     --instance "<instance_name>" \
-     --workspace "<workspace_name>" \
-     --profile-name "<profile_name>"
-   ```
-5. Execute the generated command.
-
-Important:
-- Never map tenant/account ID to `--instance`.
-- `--instance` must be a real Studio instance name.
-- Defaults are `--schema public` and `--vcluster default`.
-
-Manual fallback if all fields are already known:
+# Switch between configured LLMs
+cz-cli agent llm use my-claude
+
+# Fall back to ClickZetta built-in
+cz-cli agent llm reset
+
+# Full help
+cz-cli agent llm --help
 ```
-cz-cli profile create <name> \
-  --username <U> \
-  --password <P> \
-  --instance <instance_name> \
-  --workspace <workspace_name> \
-  --service <service_host> \
-  --schema public \
-  --vcluster default
+
+Supported providers: `anthropic`, `openai`, `openai-compatible`, `bedrock`, `google`, `azure`
+
+For `openai-compatible` (third-party relays), add `--base-url <url>`.
+
+## Error JSON reference
+
+```json

+ "next_steps": ["cz-cli setup --credential <base64>"],

+ "supported_providers": ["anthropic", "openai", "openai-compatible", "bedrock", "google", "azure"]}
 ```
 
-## Step 3 — Verify and proceed
+## Step-by-step: no credential available
+
+If the user doesn't have a base64 credential, guide them to:
 
-- Check `exit_code=0` and `ok=true` in JSON output.
-- On success, proceed with the original request using `--profile <name>`.
-- On failure, show the error and ask the user to re-check credentials.
+1. Register at `https://accounts.clickzetta.com/register?ref=cz-cli` (China) or `https://accounts.singdata.com/register?ref=cz-cli` (International)
+2. Copy the credential string from the registration page
+3. Run `cz-cli setup --credential "<base64_string>"`

 instanceName header and auto-semicolon

- success/error/successRows now set process.exitCode instead of calling process.exit()
- execute.ts no longer hijacks process.exit, reads process.exitCode after parseAsync
- Add instanceName header to HTTP requests (was causing server NullPointerException)
- Auto-append semicolon to SQL (matching Python connector behavior)
- Add return after error()/success() calls that act as control flow guards
- Fix resolveSql to check -e/positional before stdin

 ARROW + presigned URLs)

Python connector always merges 4 default configs into sqlConfig.hint.
Without these, server returns empty result sets instead of actual data.

Subject: [PATCH 087/521] fix: DECIMAL Arrow decoding - apply scale from Arrow
 type metadata
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Arrow returns DECIMAL as DecimalBigNum (raw integer × 10^scale).
Previously returned '314' for 3.14. Now correctly applies scale
from vec.type.scale to produce '3.14'.

Also: add decimalTypeInfo parsing from server metadata fields,
contextJson full alignment with Python, unlimited poll retries,
MAX_RETRIES=3, remove 504 from non-retryable.

- Fix all --no-* options for yargs strict mode (define as positive boolean with --no- negation)
- Wire isVolumeSql + processVolumeSql into execSql for PUT/GET file transfers
- Add DECIMAL precision tests (verify 3.14 not 314)
- Add all SQL flag tests (--no-truncate, --no-header, -N, --batch, --with-schema, --set, --timeout)
- Add dangerous write detection test
- Add SHOW USER VOLUME test
- 47 e2e tests passing

Subject: [PATCH 090/521] fix: cz_tool auto-appends --sync to sql commands so
 agent gets actual results

Without --sync, sql commands return immediately with job_id + RUNNING status.
Agent needs actual query results, not async job handles.

Subject: [PATCH 091/521] fix: forward.ts properly quotes args with spaces for
 execute()

Args like 'SELECT 3.14 as d' were being split by execute()'s splitArgs
because forward() joined them without quoting. Now wraps args containing
spaces/quotes in double quotes.

Subject: [PATCH 092/521] fix: exclude cz-cli skill from opencode to prevent
 recursive self-invocation

The cz-cli skill instructs agents to shell out to 'cz-cli agent run'.
When opencode loads this skill, it would recursively call itself.
Skip it since opencode already has the built-in cz_tool.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Agent architecture:
- Remove cz_tool agent tool; agent now uses bash tool to call cz-cli directly
- Add CLICKZETTA_PID recursive agent guard to prevent nested agent invocation
- Lazy-load all agent modules in index.ts so data commands skip agent bundle
- Add profile check (profiles.toml existence) before forwarding data commands
- Increase default provider timeout from 20s to 120s

Error UX:
- Unify JSON output format: remove ok field, use {data:...} / {error:{code,message}}
- Add classifyExecError() in exec.ts: AUTH_ERROR, CONNECTION_ERROR, NO_CREDENTIALS
- Add ai_message to WRITE_NOT_ALLOWED, DANGEROUS_WRITE, LIMIT_REQUIRED, SQL_ERROR, NO_RESULT
- Add e2e-routing.ts binary-level tests and classify-error.test.ts unit tests

CLI help text:
- sql: clarify --sync async default, --limit 100-row guard, --batch, examples, input priority
- workspace: add list subcommand; clarify --persist behavior
- runs: explain status/run-type enum values; remove Chinese text from deps/refill
- attempts: clarify [id]/--run-id/--task-id priority; translate ai_message to English
- profile: list valid keys in update command description
- table: clarify create DDL vs --from-file precedence
- job: clarify --limit default and --timeout error behavior

MCP server:
- Add sql-to-dt skill from cz-mcp-server (7 files); adapt absolute paths to relative

+# Dynamic Table 列校验与一致性规则
+
+你是一个 SQL 转换专家。在生成 Dynamic Table DDL 后，需要校验 schema 定义的列与 SELECT 查询产出的列是否一致。
+
+## 列数校验（必须通过）
+
+### 规则
+
+生成的 DDL 中，括号内定义的列数必须等于 AS 后面 SELECT 查询产出的列数。
+
+```sql
+CREATE OR REPLACE DYNAMIC TABLE t (
+    col1 BIGINT,    -- 1
+    col2 STRING,    -- 2
+    dt STRING       -- 3  → schema 列数 = 3
+)
+AS
+SELECT col1, col2, '2024-01-01' AS dt  -- → SELECT 列数 = 3 ✓
+FROM source;
+```
+
+### SELECT 列数计算
+
+1. 找到 AS 后面的 SELECT 子句
+2. 找到顶层 FROM（不在子查询/括号内的 FROM）
+3. 计算 SELECT 和 FROM 之间的顶层逗号数 + 1 = 列数
+4. 顶层逗号：不在括号 `()`、方括号 `[]`、引号 `''`/`""` 内的逗号
+
+### UNION ALL 的列数
+
+取第一个分支的列数（所有分支列数应一致）。
+
+### 校验失败
+
+如果 schema 列数 ≠ SELECT 列数，转换失败，报错：
+```
+Schema列数(N) != SELECT列数(M)
+```
+
+## 列名校验（可选）
+
+### 规则
+
+逐位对比 schema 中的列名与 SELECT 中推断出的别名。建议在列数校验通过后，如果 SELECT 中大部分列都有明确别名（AS 或裸标识符），开启列名校验做二次确认。
+
+### SELECT 列别名推断
+
+按优先级从高到低：
+
+1. **AS 别名**：`expression AS alias` → 别名为 `alias`
+2. **末尾标识符**：`table.column` → 别名为 `column`
+3. **裸标识符**：`column_name` → 别名为 `column_name`
+4. **无法推断**：`func(a, b)` 没有 AS → 标记为 `<expr>`，跳过校验
+
+### 对比规则
+
+- 逐位对比（第1列对第1列，第2列对第2列...）
+- 如果某位是 `<expr>`（无法推断），跳过该位
+- 对比不区分大小写
+- 不匹配时报错并列出具体不对齐的列
+
+## 静态分区注入后的列数
+
+注入静态分区列后，SELECT 列数会增加。校验应在注入后进行。
+
+### 避免重复注入
+
+在注入前检查 SELECT 中是否已包含该分区列：
+
+1. 解析 SELECT 中每个表达式的最终别名
+2. 如果别名（不区分大小写）与分区列名匹配 → 该列已存在，跳过注入
+3. 只注入 SELECT 中不存在的分区列
+
+## UNION ALL 一致性
+
+### 分支列数一致性
+
+所有 UNION ALL 分支的列数必须相同。如果不一致，记录警告：
+```
+UNION分支列数不一致: [12, 13, 12]
+```
+
+### 注入后复核
+
+静态分区注入后，再次检查各分支列数是否一致：
+```
+注入后UNION各分支列数: [13, 13, 13]
+```
+
+## 重复别名检测
+
+如果 SELECT 中有重复的列别名，记录警告：
+```
+检测到重复列别名: ['dt']
+```
+
+重复别名可能导致：
+- 列数看起来正确但实际语义错误
+- 下游查询引用歧义
+
+## 缺失分区列检测
+
+如果 SELECT 中缺少某些分区列（注入前），记录信息：
+```
+检测到缺失分区列: ['dt', 'ds']
+```
+
+这些列会在注入步骤中被自动添加。
+
+## 完整校验流程
+
+```
+1. 生成 DDL（含静态分区注入）
+2. 提取 schema 列数
+3. 提取 SELECT 列数
+4. 比较列数 → 不等则失败
+5. （可选）逐位对比列名 → 不匹配则失败
+```

+# SQL → Dynamic Table 转换规则
+
+你是一个 SQL 转换专家。给定一个 Hive/Spark SQL 的 CREATE TABLE DDL 和对应的 INSERT OVERWRITE 语句，你需要按以下规则将它们合并为一个 Dynamic Table DDL。
+
+## 总体转换公式
+
+```
+输入1: CREATE TABLE schema.table_name (...) PARTITIONED BY (...) ...
+输入2: INSERT OVERWRITE TABLE schema.table_name PARTITION(...) SELECT ... FROM ...
+输出:  CREATE OR REPLACE DYNAMIC TABLE schema.table_name (...) PARTITIONED BY (...) ... AS SELECT ... FROM ...
+```
+
+核心思想：把 CREATE TABLE 的结构定义 + INSERT OVERWRITE 的查询逻辑，合并成一个 `CREATE OR REPLACE DYNAMIC TABLE ... AS SELECT ...` 语句。
+
+## 第一步：解析 CREATE TABLE DDL
+
+从 DDL 中提取以下信息：
+
+1. **表名**（含 schema）：`schema.table_name`
+2. **普通列**：列名、数据类型、COMMENT（保持原始缩进格式）
+3. **分区列**：PARTITIONED BY 中的列名、数据类型、COMMENT
+4. **存储格式**：STORED AS PARQUET/ORC/AVRO 等
+5. **表属性**：TBLPROPERTIES 或 WITH PROPERTIES 中的键值对
+6. **分桶信息**：CLUSTERED BY / SORTED BY / RANGE CLUSTERED BY / HASH CLUSTERED BY
+7. **生命周期**：LIFECYCLE N
+8. **连接信息**：CONNECTION schema.connection_name
+9. **位置信息**：LOCATION 'path'
+
+## 第二步：解析 INSERT OVERWRITE 语句
+
+从 INSERT 语句中提取：
+
+1. **目标表名**：用于自引用检测
+2. **分区类型**：
+   - 动态分区：`PARTITION (col1, col2)` — 列名无值
+   - 静态分区：`PARTITION (col1='value1', col2=value2)` — 列名有值
+   - 混合分区：`PARTITION (static_col='value', dynamic_col)` — 部分有值
+3. **SELECT 查询**：完整的查询逻辑（含 WHERE、JOIN、GROUP BY 等）
+4. **CTE（WITH 子句）**：如果有，保留完整的 WITH ... AS (...) 结构
+5. **前置语句**：SET 语句、CREATE TEMPORARY FUNCTION 等（保留）
+
+### 需要过滤的语句
+
+从 INSERT 文件中移除：
+- `ALTER TABLE ... ADD PARTITION ...`
+- `ALTER TABLE ... DROP PARTITION ...`
+- 所有 `ALTER TABLE` 开头的语句
+- `ANALYZE TABLE` 语句
+- SQL 注释（`--` 和 `/* */`）
+
+## 第三步：组装 Dynamic Table DDL
+
+按以下顺序组装输出：
+
+```sql
+-- 可选：如果需要删除已存在的同名表，请取消下一行的注释
+-- DROP TABLE IF EXISTS schema.table_name;
+
+CREATE SCHEMA IF NOT EXISTS schema;        -- 仅当表名含 schema 时
+CREATE OR REPLACE DYNAMIC TABLE schema.table_name (
+    col1 BIGINT COMMENT '...',             -- 普通列（保持原始格式）
+    col2 STRING COMMENT '...',
+    part_col1 STRING COMMENT '...'         -- 分区列追加在普通列后面
+)
+PARTITIONED BY (part_col1, part_col2)      -- 仅列名，不含类型
+[CLUSTERED BY (...) [SORTED BY (...)] [INTO N BUCKETS]]
+[STORED AS PARQUET]
+TBLPROPERTIES ('key' = 'value')            -- 合并模板属性和原始属性
+[LIFECYCLE N]
+[CONNECTION schema.connection_name]
+[LOCATION 'original_path_dt']             -- 原路径加 _dt 后缀
+AS
+SELECT查询;                                -- 来自 INSERT OVERWRITE 的查询
+```
+
+### 关键规则
+
+1. **列定义**：普通列 + 分区列合并到一个括号内，保持原始缩进
+2. **PARTITIONED BY**：只写列名，不写类型（与 CREATE TABLE 不同）
+3. **CREATE SCHEMA**：如果表名含 `.`（如 `kscdm.table_name`），在 DDL 前加 `CREATE SCHEMA IF NOT EXISTS kscdm;`
+4. **LOCATION**：原路径加 `_dt` 后缀
+5. **DROP 语句**：注释掉的 `DROP TABLE IF EXISTS` 放在最前面
+
+## 第四步：静态分区注入
+
+当 INSERT OVERWRITE 使用静态分区（`PARTITION(col=value)`）时，需要将分区值注入到 SELECT 子句中。
+
+### 注入规则
+
+在 SELECT 的最后一个列之后、FROM 之前，按 DDL 中分区列的定义顺序追加：
+
+```sql
+-- 原始 SELECT
+SELECT col1, col2 FROM source_table
+
+-- 注入后（假设 PARTITION(year=2024, month='January')）
+SELECT col1, col2,
+    2024 AS year,
+    'January' AS month
+FROM source_table
+```
+
+### 值类型智能处理
+
+注入时根据值的类型决定是否加引号：
+
+| 值类型 | 判断规则 | 处理 | 示例 |
+|--------|----------|------|------|
+| 已有引号 | 以 `'` 或 `"` 开头结尾 | 保持原样 | `'hello'` → `'hello'` |
+| NULL | 值为 `NULL`（不区分大小写） | 不加引号 | `NULL` |
+| 布尔值 | `true` / `false`（不区分大小写） | 不加引号 | `true` |
+| 数字 | 可被 `float()` 解析 | 不加引号 | `123`, `-45.67`, `1.23e-4` |
+| SESSION_CONFIGS | 包含 `SESSION_CONFIGS(` | 不加引号 | `SESSION_CONFIGS()['dt.args.ds']` |
+| 函数调用 | 匹配 `标识符(...)` 且括号平衡 | 不加引号 | `CURRENT_DATE()`, `YEAR(col)` |
+| 字符串 | 以上都不匹配 | 加单引号，内部 `'` 转义为 `''` | `hello` → `'hello'` |
+
+### UNION ALL 处理
+
+如果 SELECT 包含 UNION ALL，每个分支都要独立注入分区列：
+
+```sql
+SELECT col1, col2,
+    2024 AS year
+FROM table_a
+UNION ALL
+SELECT col1, col2,
+    2024 AS year
+FROM table_b
+```
+
+### CTE + UNION ALL
+
+如果有 WITH 子句，先分离 CTE 部分，只对主查询中的 UNION 分支注入。
+
+### 已存在的分区列
+
+如果 SELECT 中已经包含了某个分区列（通过 `AS alias` 或末尾标识符检测），则跳过该列的注入，避免重复。
+
+## 第五步：日期函数后处理
+
+生成 DDL 后，对整个 DDL 文本做一次全局替换：
+
+| 原始形式 | 替换为 |
+|----------|--------|
+| `DATE_SUB(expr, INTERVAL N DAY)` | `sub_days(expr, N)` |
+| `DATE_ADD(expr, INTERVAL N DAY)` | `sub_days(expr, -N)` |
+
+这一步确保最终输出统一使用 `sub_days` 函数。
+
+> 注意：在 SQL 引擎中，`SUB_DAYS` 是 `DATE_SUB` 的别名，两者等价。统一使用 `sub_days` 是为了保持输出一致性。
+
+## 第六步：表属性模板合并
+
+默认模板属性：`data_lifecycle = 15`
+
+合并规则：
+- 模板属性作为基础
+- 原始 DDL 中的 TBLPROPERTIES 覆盖同名模板属性
+- 最终结果写入 TBLPROPERTIES
+
+```sql
+-- 模板: data_lifecycle=15
+-- 原始DDL: TBLPROPERTIES('compression'='snappy', 'data_lifecycle'='30')
+-- 合并结果:
+TBLPROPERTIES ('data_lifecycle' = '30', 'compression' = 'snappy')
+-- data_lifecycle 保留原始值 30，compression 来自原始DDL
+```
+
+## 完整示例
+
+### 输入1：DDL
+```sql
+CREATE TABLE IF NOT EXISTS sales_data (
+    id BIGINT COMMENT '销售记录ID',
+    product_name STRING COMMENT '产品名称',
+    sales_amount DECIMAL(12,2) COMMENT '销售金额'
+)
+PARTITIONED BY (
+    year INT COMMENT '年份',
+    month INT COMMENT '月份'
+)
+STORED AS PARQUET
+LOCATION '/data/warehouse/sales_data';
+```
+
+### 输入2：INSERT OVERWRITE
+```sql
+INSERT OVERWRITE TABLE sales_data
+PARTITION (year, month)
+SELECT
+    s.id,
+    s.product_name,
+    s.price * s.quantity AS sales_amount,
+    YEAR(s.sales_date) AS year,
+    MONTH(s.sales_date) AS month
+FROM raw_sales s
+WHERE s.status = 'completed';
+```
+
+### 输出：Dynamic Table DDL
+```sql
+-- 可选：如果需要删除已存在的同名表，请取消下一行的注释
+-- DROP TABLE IF EXISTS sales_data;
+
+CREATE OR REPLACE DYNAMIC TABLE sales_data (
+    id BIGINT COMMENT '销售记录ID',
+    product_name STRING COMMENT '产品名称',
+    sales_amount DECIMAL(12,2) COMMENT '销售金额',
+    year INT COMMENT '年份',
+    month INT COMMENT '月份'
+)
+PARTITIONED BY (year, month)
+STORED AS PARQUET
+TBLPROPERTIES ('data_lifecycle' = '15')
+LOCATION '/data/warehouse/sales_data_dt'
+AS
+SELECT
+    s.id,
+    s.product_name,
+    s.price * s.quantity AS sales_amount,
+    YEAR(s.sales_date) AS year,
+    MONTH(s.sales_date) AS month
+FROM raw_sales s
+WHERE s.status = 'completed';
+```

+# SQL 占位符 → SESSION_CONFIGS() 转换规则
+
+你是一个 SQL 转换专家。在将传统 SQL 转换为 Dynamic Table SQL 时，需要将各种占位符格式统一转换为 `SESSION_CONFIGS()` 函数调用。
+
+## 占位符格式统一
+
+首先将所有旧格式统一为 `${...}` 格式：
+
+| 旧格式 | 统一为 |
+|--------|--------|
+| `{{ var }}` | `${var}` |
+| `{{ ds }}` | `${ds}` |
+| `{{region}}` | `${region}` |
+
+转换正则：`\{\{\s*([^}]+)\s*\}\}` → `${\1}`
+
+## 基本替换规则
+
+### 简单变量
+
+| 输入 | 输出 |
+|------|------|
+| `${ds}` | `SESSION_CONFIGS()['dt.args.ds']` |
+| `${region}` | `SESSION_CONFIGS()['dt.args.region']` |
+| `${hour}` | `SESSION_CONFIGS()['dt.args.hour']` |
+
+### nodash 变量（特殊处理）
+
+变量名中包含 `nodash` 时，自动包装 DATE_FORMAT，但变量名保持原样：
+
+| 输入 | 输出 |
+|------|------|
+| `${ds_nodash}` | `DATE_FORMAT(SESSION_CONFIGS()['dt.args.ds_nodash'], 'yyyyMMdd')` |
+| `${dsnodash}` | `DATE_FORMAT(SESSION_CONFIGS()['dt.args.dsnodash'], 'yyyyMMdd')` |
+
+注意：变量名保持原样（`ds_nodash` 不会变成 `ds`），只是外层包 DATE_FORMAT。
+
+### 带运算的变量
+
+最终输出统一使用 `sub_days` 函数（有一个后处理步骤会将所有 `DATE_SUB`/`DATE_ADD` 转为 `sub_days`）：
+
+| 输入 | 最终输出 |
+|------|----------|
+| `${ds - 1}` | `DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')` |
+| `${ds + 7}` | `DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], -7), 'yyyy-MM-dd')` |
+| `${ds_nodash - 1}` | `DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds_nodash'], 1), 'yyyyMMdd')::STRING` |
+
+规则：
+- `-` 运算 → `sub_days(..., N)`（N 为正数）
+- `+` 运算 → `sub_days(..., -N)`（N 取反为负数）
+- 外层包 `DATE_FORMAT`，格式根据变量名决定：
+  - 含 `nodash` → `'yyyyMMdd'`
+  - 不含 `nodash` → `'yyyy-MM-dd'`
+- 含 `nodash` 的变量带运算时，追加 `::STRING` 类型转换
+
+注意：这是最终输出形式。中间步骤可能先生成 `DATE_SUB`/`DATE_ADD`，但最终会被后处理统一转为 `sub_days`。
+
+### macros.ds_add 函数
+
+| 输入 | 输出 |
+|------|------|
+| `${macros.ds_add(ds, -1)}` | `DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')` |
+| `${macros.ds_add(ds, 7)}` | `DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], -7), 'yyyy-MM-dd')` |
+
+注意：`macros.ds_add` 的第二个参数与 `sub_days` 的参数符号相反。`macros.ds_add(ds, -1)` 表示 ds 减 1 天，对应 `sub_days(ds, 1)`（正数=减天数）；`macros.ds_add(ds, 7)` 表示 ds 加 7 天，对应 `sub_days(ds, -7)`（负数=加天数）。
+
+## 引号上下文规则
+
+占位符的处理方式取决于它所在的引号上下文：
+
+### 情况1：占位符在单引号内（纯占位符）
+
+```sql
+-- 输入
+WHERE dt = '${ds}'
+-- 输出（去除外层引号，直接替换）
+WHERE dt = SESSION_CONFIGS()['dt.args.ds']
+```
+
+### 情况2：占位符在单引号内（混合内容）
+
+当引号内同时包含占位符和字面文本时，使用 CONCAT：
+
+```sql
+-- 输入
+WHERE dt = '${ds_nodash}_done'
+-- 输出
+WHERE dt = CONCAT(DATE_FORMAT(SESSION_CONFIGS()['dt.args.ds_nodash'], 'yyyyMMdd'), '_done')
+```
+
+```sql
+-- 输入
+WHERE path = '/data/${region}/output'
+-- 输出
+WHERE path = CONCAT('/data/', SESSION_CONFIGS()['dt.args.region'], '/output')
+```
+
+### 情况3：占位符不在引号内
+
+```sql
+-- 输入
+WHERE dt = ${ds}
+-- 输出
+WHERE dt = SESSION_CONFIGS()['dt.args.ds']
+```
+
+### 情况4：占位符在单引号内，且是日期运算
+
+```sql
+-- 输入
+WHERE dt = '${ds - 1}'
+-- 输出（去除外层引号，添加 ::STRING 类型转换）
+WHERE dt = DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')::STRING
+```
+
+### 引号内的引号选择
+
+当替换后的表达式仍然处于单引号字符串内部时（如 CONCAT 场景），SESSION_CONFIGS 的键名使用双引号以避免引号冲突：
+```sql
+-- 在 CONCAT 等单引号上下文中
+CONCAT('prefix_', SESSION_CONFIGS()["dt.args.ds"])
+
+-- 独立表达式（外层引号已去除）
+SESSION_CONFIGS()['dt.args.ds']
+```
+
+## 静态分区中的占位符
+
+静态分区值中的占位符替换后，值会被注入到 SELECT 子句：
+
+```sql
+-- 输入
+INSERT OVERWRITE TABLE t PARTITION(dt='${ds}', region='${region}')
+SELECT col1 FROM source;
+

+    SESSION_CONFIGS()['dt.args.region'] AS region
+FROM source;
+```
+
+## 不可识别的表达式
+
+对于无法解析的复杂表达式（如 Airflow Jinja 模板），进行清洗：
+1. 将 Python strftime 格式符转为 SQL 风格：`%Y`→`yyyy`, `%m`→`MM`, `%d`→`dd`, `%H`→`HH`
+2. 非字母数字下划线字符替换为 `_`
+3. 合并连续下划线，去除首尾下划线
+4. 用清洗后的字符串作为 SESSION_CONFIGS 的键名
+
+```sql
+-- 输入
+${execution_date.strftime("%H00")}
+-- 清洗后键名: execution_date_strftime_HH00
+-- 输出
+SESSION_CONFIGS()['dt.args.execution_date_strftime_HH00']
+```
+
+## 完整示例
+
+### 输入
+```sql
+INSERT OVERWRITE TABLE kscdm.dim_table
+PARTITION(p_date='{{ ds_nodash }}_done', product='done', dt='{{ ds }}')
+SELECT id, name
+FROM source_table
+WHERE dt = '{{ ds }}'

+# Dynamic Table Refresh 与调度文件生成规则
+
+你是一个 SQL 转换专家。在生成 Dynamic Table DDL 之后，还需要生成配套的 refresh 语句、回填语句和调度配置文件。
+
+## Refresh 语句生成
+
+### 变量提取
+
+从转换后的 DDL 中提取所有 `SESSION_CONFIGS()['dt.args.XXX']` 中的变量名 XXX，去重后排序。
+
+注意：只提取 DDL 中实际出现的变量名。例如如果 DDL 中只有 `SESSION_CONFIGS()['dt.args.ds_nodash']`，则只生成 `ds_nodash` 一个变量的 SET 语句。
+
+### 三类 Refresh 文件
+
+对每个转换的表，生成三类文件：
+
+#### 1. 当前周期 refresh（`表名_refresh.sql`）
+
+```sql
+set dt.args.ds = ${ds};
+set dt.args.region = ${region};
+REFRESH DYNAMIC TABLE schema.table_name PARTITION(ds = '${ds}', region = '${region}');
+```
+
+规则：
+- 为每个提取到的变量生成一条 `set dt.args.变量名 = ${变量名};`
+- 变量按字母序排列
+- PARTITION 子句只包含静态分区列（从原始 INSERT OVERWRITE 的 PARTITION 子句中提取）
+- 分区值使用 `'${变量名}'` 格式
+
+#### 2. 上一周期 refresh（`表名_prev_refresh.sql`）
+
+```sql
+set dt.args.ds = ${prev_ds};
+set dt.args.region = ${prev_region};
+REFRESH DYNAMIC TABLE schema.table_name PARTITION(ds = '${prev_ds}', region = '${prev_region}');
+```
+
+规则：每个变量名加 `prev_` 前缀。
+
+#### 3. 回填语句（`表名_backfill.sql`）
+
+```sql
+set cz.optimizer.incremental.backfill.enabled = TRUE;
+
+INSERT OVERWRITE schema.table_name
+SELECT *
+FROM ext_schema.table_name
+WHERE ds = '${ds}' AND region = '${region}';
+```
+
+规则：
+- 固定的 backfill 开关 SET 语句
+- 从扩展表（ext_schema）SELECT * 到目标表
+- WHERE 条件使用静态分区列（从原始 INSERT OVERWRITE 的 PARTITION 子句中提取）
+
+### 无分区表
+
+如果表没有静态分区变量：
+- 只生成当前周期 refresh：`REFRESH DYNAMIC TABLE schema.table_name;`
+- 不生成 prev_refresh 和 backfill 文件
+
+### 扩展表名规则
+
+- 如果指定了 `ext_schema`：`ext_schema.table_name`
+
+## 完整示例
+
+### 输入（转换后的 DDL 含以下变量）
+
+DDL 中包含：`SESSION_CONFIGS()['dt.args.ds']` 和 `SESSION_CONFIGS()['dt.args.region']`
+原始 PARTITION：`PARTITION(dt='${ds}', region='${region}')`
+
+### 输出
+
+**refresh.sql:**
+```sql
+set dt.args.ds = ${ds};
+set dt.args.region = ${region};
+REFRESH DYNAMIC TABLE kscdm.my_table PARTITION(dt = '${ds}', region = '${region}');
+```
+
+**prev_refresh.sql:**
+```sql
+set dt.args.ds = ${prev_ds};
+set dt.args.region = ${prev_region};
+REFRESH DYNAMIC TABLE kscdm.my_table PARTITION(dt = '${prev_ds}', region = '${prev_region}');
+```
+
+**backfill.sql:**
+```sql
+set cz.optimizer.incremental.backfill.enabled = TRUE;
+
+INSERT OVERWRITE kscdm.my_table
+SELECT *
+FROM ext_kscdm.my_table
+WHERE dt = '${ds}' AND region = '${region}';
+```

+# Dynamic Table 自引用表转换规则
+
+你是一个 SQL 转换专家。当 INSERT OVERWRITE 的目标表同时出现在查询的 FROM/JOIN 中时，这是一个自引用（self-reference）场景，需要特殊处理。
+
+## 自引用检测
+
+### 判断条件
+
+1. 从 INSERT OVERWRITE 语句中提取目标表名（含 schema）
+2. 在 SELECT 查询的 FROM 和 JOIN 子句中搜索该表名
+3. 排除 PARTITION 子句中的表名引用（不算自引用）
+4. 如果在 FROM/JOIN 中找到目标表名 → 判定为自引用
+
+### 示例
+
+```sql
+-- 目标表: kscdm.daily_sales
+INSERT OVERWRITE TABLE kscdm.daily_sales PARTITION(ds='${ds}')
+SELECT current.id, current.amount
+FROM source_sales current
+LEFT JOIN kscdm.daily_sales prev ON current.id = prev.id  -- ← 自引用
+WHERE prev.ds = '${ds - 1}';
+```
+
+## 转换规则
+
+自引用表的转换与普通表基本相同，但有以下区别：
+
+### 1. 显式 Schema 声明
+
+自引用表必须在 CREATE DYNAMIC TABLE 中显式声明完整的列定义（含类型），因为 SQL 引擎需要这些信息来推理自依赖列的类型：
+
+```sql
+CREATE OR REPLACE DYNAMIC TABLE kscdm.daily_sales (
+    id BIGINT COMMENT '...',
+    amount DECIMAL(10,2) COMMENT '...',
+    ds STRING COMMENT '...'
+)
+PARTITIONED BY (ds)
+AS
+SELECT current.id, current.amount,
+    SESSION_CONFIGS()['dt.args.ds'] AS ds
+FROM source_sales current
+LEFT JOIN kscdm.daily_sales prev ON current.id = prev.id
+WHERE prev.ds = DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')::STRING;
+```
+
+### 2. 查询中保留自引用
+
+转换后的 AS 子句中，自引用表名保持不变，不做任何替换。SQL 引擎会自动处理自引用的版本管理。
+
+## 常见自引用场景
+
+### 日环比计算
+
+```sql
+-- 输入
+INSERT OVERWRITE TABLE metrics PARTITION(ds='${ds}')
+SELECT t.id, t.value,
+    t.value - prev.value AS daily_change
+FROM source t
+LEFT JOIN metrics prev ON t.id = prev.id AND prev.ds = '${ds - 1}';
+
+-- 输出
+CREATE OR REPLACE DYNAMIC TABLE metrics (
+    id BIGINT, value DECIMAL(10,2), daily_change DECIMAL(10,2), ds STRING
+)
+PARTITIONED BY (ds)
+AS
+SELECT t.id, t.value,
+    t.value - prev.value AS daily_change,
+    SESSION_CONFIGS()['dt.args.ds'] AS ds
+FROM source t
+LEFT JOIN metrics prev ON t.id = prev.id
+    AND prev.ds = DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')::STRING;

+# SQL → Dynamic Table 完整转换工作流
+
+当用户给你一组 CREATE TABLE DDL 和 INSERT OVERWRITE SQL，要求转换为 Dynamic Table 时，按以下步骤顺序执行。
+
+每一步的详细规则在对应的 skill 文件中，你需要同时引用它们。
+
+## 工作流步骤
+
+### Step 1: 预处理输入
+
+从 INSERT OVERWRITE 文件中移除：
+- 所有 `ALTER TABLE` 语句
+- `ANALYZE TABLE` 语句
+- SQL 注释（`--` 和 `/* */`）
+
+保留：CREATE TABLE、INSERT OVERWRITE、WITH、SET、CREATE TEMPORARY FUNCTION。
+
+### Step 2: 占位符替换
+
+按 `sql2dt-placeholder-rules.md` 中的规则：
+1. 统一占位符格式（`{{ }}` → `${ }`）
+2. 替换所有占位符为 `SESSION_CONFIGS()` 调用
+3. 处理 nodash 变量、日期运算、macros 函数
+4. 根据引号上下文决定处理方式（去引号 / CONCAT / 直接替换）
+
+### Step 3: 自引用检测
+
+按 `sql2dt-self-reference-rules.md` 中的规则：
+1. 检查 INSERT OVERWRITE 目标表是否出现在 FROM/JOIN 中
+2. 如果是自引用表，标记并在后续步骤中添加注释、使用显式 schema
+
+### Step 4: 核心转换
+
+按 `sql2dt-conversion-rules.md` 中的规则：
+1. 解析 CREATE TABLE DDL（提取列、分区、属性等）
+2. 解析 INSERT OVERWRITE（提取查询、分区类型）
+3. 组装 `CREATE OR REPLACE DYNAMIC TABLE ... AS SELECT ...`
+4. 注入静态分区值到 SELECT（智能引号处理）
+5. 合并表属性模板（默认 `data_lifecycle=15`）
+6. 处理 UNION ALL（每个分支独立注入）
+7. 日期函数后处理：将所有 `DATE_SUB/DATE_ADD` 统一转为 `sub_days`
+
+### Step 5: 列校验
+
+按 `sql2dt-column-validation-rules.md` 中的规则：
+1. 计算 schema 列数和 SELECT 列数
+2. 验证两者相等
+3. 检查重复别名和缺失分区列
+4. UNION ALL 分支列数一致性检查
+
+### Step 6: 生成配套文件
+
+按 `sql2dt-refresh-rules.md` 中的规则：
+1. 从 DDL 中提取所有 SESSION_CONFIGS 变量
+2. 生成当前周期 refresh 语句
+3. 生成上一周期 prev_refresh 语句
+4. 生成回填 backfill 语句
+
+## 输出清单
+
+对每个表，最终输出：
+
+| 文件 | 内容 | 条件 |
+|------|------|------|
+| `表名.sql` | Dynamic Table DDL | 始终生成 |
+| `表名_refresh.sql` | 当前周期 REFRESH 语句 | 始终生成 |
+| `表名_prev_refresh.sql` | 上一周期 REFRESH 语句 | 仅有分区变量时 |
+| `表名_backfill.sql` | 回填语句 | 仅有分区变量时 |
+
+## 快速判断路径
+
+```
+输入 DDL + INSERT OVERWRITE
+  │
+  ├─ 有占位符？ → Step 2 占位符替换
+  │
+  ├─ 自引用？ → Step 3 特殊处理
+  │
+  ├─ 有静态分区？ → Step 4 注入分区值到 SELECT
+  │
+  ├─ 有 UNION ALL？ → Step 4 每个分支独立注入
+  │
+  └─ 生成 DDL → Step 5 校验 → Step 6 生成配套文件

-Commands are passed as a single string and executed by the built-in cz-cli engine. Output is always JSON for machine parsing.
-
-Common commands:
-- sql "SELECT * FROM table LIMIT 10" — execute SQL
-- table list — list tables
-- table describe <name> — describe table schema
-- schema list — list schemas
-- profile list — list connection profiles
-- task list — list scheduled tasks
-- runs list — list task run instances
-- status — check connection status
-
-The --output json flag is automatically appended. Use --profile <name> to target a specific connection profile.

Subject: [PATCH 094/521] fix: resolve TUI e.zod circular dependency crash and
 improve --help routing

- event.ts: replace SessionID.zod with z.string().startsWith("ses") to avoid
  circular dependency in bundled binary where SessionID may be undefined at
  module load time
- tui.ts: cast sessionID string to SessionID.make() to satisfy brand type
- index.ts: route --help and no-args through forward() so TUI modules are
  never loaded for help requests
- agent.ts: update description to mention AI agent and point to cz-cli agent --help

Subject: [PATCH 096/521] fix: remove unused --silent/--verbose, fix TUI crash,
 full --help coverage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- cli.ts: remove --silent and --verbose (defined but never used)
- event.ts: fix circular dependency crash (SessionID.zod → z.string())
- tui.ts: cast sessionID string to SessionID brand type
- index.ts: route agent/run/setup --help through forward() to avoid TUI load
- agent.ts: improve description with progressive disclosure pointer
- test/e2e-help.ts: expand from 42 to 74 --help tests covering all subcommands
  including task flow/* and all runs/profile/table/schema subcommands
- package.json: add test:ci, test:all, build:local scripts

Subject: [PATCH 097/521] =?UTF-8?q?fix:=20resolve=20TUI=20crash=20?=
 =?UTF-8?q?=E2=80=94=20lazy=20withStatics=20getters=20+=20sequential=20imp?=
 =?UTF-8?q?orts?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three root causes fixed:

1. schema.ts: withStatics() now defines lazy getters instead of eagerly
   calling methods(schema). Prevents .zod/.make/.array access from
   crashing when circular-dep modules aren't yet initialised in the
   bundled binary.

2. index.ts: replace Promise.all() parallel dynamic imports with
   sequential awaits. Bun's bundler evaluates modules in a different
   order than source; parallel imports trigger TDZ errors on
   interdependent modules.

3. share/share-next.ts + share/session.ts: wrap defaultLayer in
   Layer.suspend() so the layer reference is resolved at runtime, not
   at module evaluation time.

Also: log.ts clone() now uses createFresh() to avoid mutating the
cached Log.Default instance via tag().

All 138 e2e tests pass (8 unit + 9 routing + 74 help + 47 integration).

+
+## Output Formats
+
+- `-o json` (default) — single-line JSON, best for parsing
+- `-o toon` — line-per-field, good for `grep`/`head`
+- `-o table` / `-o csv` / `-o pretty` — human-readable
+- `--field <name>` — extract one field as raw text
+
+## Key Rules
+
+1. **SQL is async by default**. Use `--sync` for SELECT when you need data immediately.
+2. **Write operations require `--write` flag** (INSERT/UPDATE/DELETE/CREATE/DROP).
+3. **Always pass `--type` when creating tasks** (SQL/PYTHON/SHELL/SPARK/FLOW).
+4. **Flow tasks use `task flow *` commands exclusively** — never use `task save-content` or `task online` on flow nodes.
+5. **Paginated results**: `list` commands return page 1 only. Check `ai_message` in response for next-page hints.
+6. **State-changing operations** (online/offline/execute/delete/refill): confirm intent with user first.
+7. **Multi-environment**: use `--profile <name>` to target a specific environment.
+8. **On `NO_PROFILE` error**: guide user to run `cz-cli setup`.
+
+## Companion Skills
+
+When the task involves writing SQL or Python task code, load these skills for accuracy:
+- **lakehouse-doc** — SQL syntax, functions, data types, DDL/DML for ClickZetta dialect
+- **lakehouse-python-sdk** — Python/Shell task development, BulkLoad, IGS, connector

Subject: [PATCH 107/521] fix: resolve multiple cz-cli bugs from test report

- job status: use requestRaw instead of request for /lh/getJob (fixes crash)
- profile create: return on verification failure to prevent saving invalid profile
- workspace API: add env:prod header and accept code 200 (fixes task/runs 400)
- attempts list: remove duplicate RUN_NOT_FOUND error output
- agent: replace legacy status/ask commands with run/llm definitions
- SKILL.template: update agent command references
- test: update agent help test expectations

Subject: [PATCH 108/521] fix(cz-cli): resolve 12 bugs from test report

Bug 1: runs list date format - send numeric timestamps instead of strings
Bug 2: output formats table/csv/jsonl/text/toon - add text case, handle primitive arrays
Bug 3: --field support for sql command + array index syntax (data[0].name)
Bug 4: workspace use defaults to --persist=true
Bug 5: custom --session string validates existence before prompting
Bug 6: agent llm accepts global -o parameter
Bug 8: agent run --format choices corrected to default/json/a2a
Bug 9: --dangerously-skip-permissions uses 'always' reply + permissive rules
Bug 10: sql status uses requestRaw + get_result_request (matches job status)
Bug 11: TASK_TYPE_MAP corrected: SQL=4, PYTHON=7, SHELL=5
Bug 12: task online .version(false) avoids yargs reserved word warning
Bug 13: deleteTask adds operateUser field (server-side fix still needed)

Date: Mon, 11 May 2026 11:24:03 +0800
Subject: [PATCH 109/521] fix: respect user-specified -o/--output format, fix
 agent --help

- execute() no longer force-appends --output json when user specifies -o
- agent --help now shows 'run' command instead of non-existent 'ask'/'status'
- Update e2e test for pretty output (now multi-line)

Subject: [PATCH 110/521] fix(cz-cli): resolve 6 bugs from 0.3.5 test report

- #2: sql -B batch mode now outputs all statement results
- #3: --truncate keeps total length within threshold (suffix-aware slice)
- #4: --job-profile no longer falls through to SQL execution
- #5: task save-content adds collectType:0 to persist content correctly
- #6: task save-config exposes --active-start-time/--active-end-time
- #10: migration log only shows on first run (use Database.Path as marker)
- #11: SKILL.template.md embedded via text import for compiled binary
- build:local no longer overwrites ~/.local/bin/cz-cli

 Available profiles: read `~/.clickzetta/profiles.toml` or run `cz-cli profile list`.
 
+## Adding a new profile
+
+**Trigger conditions:** User says "configure new environment", "add profile", "can't connect", mentions an unknown profile name, or provides connection credentials.
+
+### Step 1 — Collect information (guided Q&A)
+
+If all required fields are already provided, skip directly to Step 2.
+
+Otherwise, ask for missing ones. Accept all at once or prompt one by one.
+
+**Required fields:**
+
+| Field | Question to ask | Example |
+|-------|----------------|---------|
+| `service` | Which cloud region? (see table below, or provide the service endpoint directly) | `cn-shanghai-alicloud.api.clickzetta.com` |
+| `instance` | What is the instance name? | `billingsh` |
+| `workspace` | What is the workspace name? | `meter_n_bill` |
+| `username` | What is the username? | `billing_admin` |
+| `password` | What is the password? | — |
+| `name` | What should this profile be named? (suggested format below) | `billingsh` |
+
+**Common service endpoints (offer as options):**
+
+| Region | service | Suggested profile prefix |
+|--------|---------|--------------------------|
+| Alibaba Cloud East China 2 (Shanghai) | `cn-shanghai-alicloud.api.clickzetta.com` | `cn-shanghai` |
+| Tencent Cloud East China (Shanghai) | `ap-shanghai-tencentcloud.api.clickzetta.com` | `ap-shanghai` |
+| Tencent Cloud North China (Beijing) | `ap-beijing-tencentcloud.api.clickzetta.com` | `ap-beijing` |
+| Tencent Cloud South China (Guangzhou) | `ap-guangzhou-tencentcloud.api.clickzetta.com` | `ap-guangzhou` |
+| AWS China (Beijing) | `cn-north-1-aws.api.clickzetta.com` | `cn-north-1` |
+
+**Inference rules (reduce unnecessary questions):**
+- If the user describes a cloud region in natural language (e.g. "Alibaba Cloud Shanghai", "Tencent Cloud Beijing", "阿里云上海", "腾讯云北京"), look up the service endpoint from the table above — do NOT ask the user to provide it again.
+- If the user hasn't provided a profile name, suggest `<prefix>-<instance>` using the prefix from the table (e.g. `cn-shanghai-billingsh`). Confirm with the user or proceed if they don't object.
+
+### Step 2 — Create profile
+
+Run `cz-cli profile create` with all collected fields:
+
+```bash
+cz-cli profile create <name> \
+  --username <username> \
+  --password <password> \
+  --instance <instance> \
+  --workspace <workspace> \
+  --service <service> \
+  --schema public \
+  --vcluster default
+```
+
+### Step 3 — Verify connection
+
+After creating, run:
+
+```bash
+cz-cli status --profile <name>
+```
+
+A successful response looks like:
+```json
+{"data": {"connected": true, "workspace": "...", "time_ms": ...}}
+```
+
+If it fails, report the error and ask the user to double-check credentials or service endpoint.

- Revert skill name from cz-cli-v2 back to cz-cli (fixes skill guard bypass)
- Add CLICKZETTA_AGENT_RUNNING env var: nested cz-cli agent run refuses to start
- Add postinstall cleanup for users who already have cz-cli-v2 deployed
- Add default query_tag to exec SQL calls

 You have no direct Lakehouse access. Always delegate via cz-cli.
 
+## Capabilities
+
+### SQL & Data Operations
+- Execute any SQL against Lakehouse: SELECT, DDL (CREATE/ALTER/DROP TABLE, SCHEMA, VIEW), DML (INSERT, UPDATE, DELETE, MERGE INTO)
+- Run async jobs and fetch results
+- Preview table data and row counts
+
+### Table & Schema Management
+- List, describe, create, and drop tables and schemas
+- View table history, indexes, partitions, and statistics
+- Add or update column/table comments
+- Create Dynamic Tables for auto-incremental ETL (ODS→DWD→DWS pipelines)
+- Create Materialized Views for pre-computed aggregations
+- Create Table Streams to capture INSERT/UPDATE/DELETE changes for CDC UPSERT
+
+### Studio Task Management
+- Create, configure, deploy, and delete Studio tasks (SQL, Shell, Python, integration, flow)
+- Save task content and cron schedule
+- Deploy, undeploy, and execute tasks ad-hoc
+- Monitor run instances: list, detail, wait, logs, stop, rerun, backfill
+- View run statistics and dependencies
+
+### Data Sync Pipelines
+- Create single-table realtime CDC sync tasks (MySQL/PostgreSQL/SQL Server → Lakehouse, task_type=28)
+- Create multi-table or whole-database CDC sync tasks — mirror, merge, or sharded-table consolidation (task_type=281)
+- Create offline batch sync tasks with Cron scheduling — single-table (task_type=10) or multi-table (task_type=291)
+- Manage sync task lifecycle: start, stop, offline, backfill, add tables, re-sync individual tables
+
+### Data Ingestion Pipelines
+- Create continuous OSS/S3/COS ingest PIPE (LIST_PURGE scan mode or EVENT_NOTIFICATION mode)
+- Create continuous Kafka ingest PIPE using READ_KAFKA function
+- One-shot file import from URL, local path, or Volume (COPY INTO)
+- Manage PIPE lifecycle: pause, resume, adjust batch interval, view load history
+
+### Data Recovery
+- Query data at a historical point in time (Time Travel: TIMESTAMP AS OF)
+- Roll back a table to a previous version (RESTORE TABLE)
+- Recover accidentally dropped tables, dynamic tables, or materialized views (UNDROP TABLE)
+- Inspect change history (DESC HISTORY) and deleted objects (SHOW TABLES HISTORY)

-## Execution
+## Execution strategy
+
+**MANDATORY: Follow this order every time. No exceptions.**
+
+**Step 1 — MUST check LLM first:**
+
+```bash
+cz-cli agent llm show
+```
+
+**Step 2 — If active LLM is configured (kind != "none"), you MUST use agent run:**
 
 ```bash
 cz-cli agent run "<request>" --format a2a --dangerously-skip-permissions
 ```
 
+Do NOT use direct cz-cli subcommands when an active LLM is available. Always delegate the full request to `cz-cli agent run`.
+
+**Step 3 — ONLY if no active LLM (kind: "none" or empty list), fall back to direct commands:**
+
+Decompose the request into concrete `cz-cli` subcommands (`sql`, `schema`, `table`, `task`, `runs`, `job`, `datasource`, `profile`, etc.), execute them, and synthesize the result.
+
+Use direct commands for local setup and diagnostics even when agent path is available: `cz-cli profile ...`, `cz-cli -p <profile> status`, `cz-cli agent llm ...`, `cz-cli --help`.
+
 With session continuity:

Subject: [PATCH 152/521] feat: support system params and time expressions in
 task save-content

- Add inferParamType() to auto-detect paramType=system for built-in
  params (bizdate, sys_biz_day, sys_biz_datetime, sys_plan_day,
  sys_plan_datetime, sys_plan_timestamp, sys_task_id, sys_task_name,
  sys_task_owner) and time expressions starting with $[
- Refactor parseParamValueList() to follow style guide (functional,
  no let/for-loop)
- task content command now returns params, input_params, output_params
  fields from raw API response
- Update locale, SKILL.template.md and cz-cli-inner SKILL.md to
  document new --params behavior

  merges manual params as defaults; --param flags override saved values
- system params (bizdate etc.) are excluded from auto-merge since they
  are not available in adhoc mode — user must pass them via --param
- warn to stderr when script contains unresolved ${placeholders} after
  merge (SQL tasks will fail; Python/Shell silently keep literal string)
- consolidate getTaskDetail call: single fetch regardless of --vc flag
- runs refill --from/--to describe updated to clarify YYYY-MM-DD vs
  ISO datetime for hourly/minutely task backfills
- update SKILL.md and SKILL.template.md with new execute and refill behavior

 ### Rule 4 — Paginated results are not complete data
 
 All `list` commands return only page 1 by default (typically 10 items). The `ai_message` field in the response contains the total count and the command to fetch the next page — treat it as the authoritative next-step hint and follow it. Never treat a first-page result as the full dataset.

Subject: [PATCH 157/521] fix: JDBC task execute and content support datasource
 binding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- task content now parses adhocConfigs JSON and returns datasource_id,
  session_schema_name, ds_type fields for JDBC tasks
- task execute auto-resolves datasourceId/sessionSchemaName/dsType from
  saved adhocConfigs; --datasource and --database flags allow override
- SDK ExecuteAdhocParams extended with optional datasourceId,
  sessionSchemaName, dsType fields passed to /adhoc/execute endpoint
- fixes "获取数据源配置异常" error when executing JDBC tasks via CLI

Subject: [PATCH 158/521] fix: JDBC execute resolves dsType from datasource
 API, supports name or id

- --datasource now accepts datasource name or numeric ID (string type)
- dsType is auto-resolved via resolveDatasource() when --datasource is
  provided, fixing "dsType is null" error on new JDBC tasks
- export resolveDatasource and ResolvedDatasource from datasource.ts
- adhocConfigs parsing moved into execute command scope (was missing)
- new JDBC tasks (no saved adhocConfigs) now work with:
  cz-cli task execute <task> --datasource <name|id> --database <db>

Subject: [PATCH 159/521] fix: add missing JDBC-supported datasource types to
 DS_TYPE_MAP

Add Aurora MySQL (39), Aurora PostgreSQL (40), PolarDB PostgreSQL (48)
which are supported by JDBC tasks but were missing from the type map.
Also fix PolarDB (19) display name to "PolarDB MySQL" for clarity.

Subject: [PATCH 161/521] feat(otel): unified per-prompt trace system, replace
 @devtheops/opencode-plugin-otel

- Self-built OTel plugin at packages/opencode/src/plugin/otel/ with
  per-prompt trace isolation (each user input gets its own traceId)
- shell.env hook injects CLICKZETTA_TRACEPARENT into child processes
  with session traceId + unique spanId per tool call
- SDK currentTraceparent() returns env directly (no spanId regeneration)
  ensuring HTTP headers match the injected trace context
- cz-cli currentTraceContext() parses env directly for log consistency
- Effect OtlpLogger gets session trace fallback via withSessionTraceFallback
- Removed Proxy context manager hack from observability.ts
- Removed @devtheops/opencode-plugin-otel dependency

-# Job Performance Analyzer
-
-## 概述
-
-自动诊断 Clickzetta Job 性能问题的工具，分析执行计划和运行概况，识别瓶颈并给出参数优化建议。
-
-## 已实现规则
-
-**Stage/Operator 级别优化** (9条规则):
-- `refresh_type_detection` - 增量/全量刷新判断
-- `single_dop_aggregate` - 单并行度聚合优化（三阶段聚合、Bloom Filter 收集检测）
-- `hash_join_optimization` - Broadcast Hash Join 优化
-- `tablesink_dop` - TableSink DOP 自动调整检测
-- `max_dop_check` - 最大 DOP 限制提示
-- `spilling_analysis` - 内存溢出分析
-- `skew_detection` - 数据倾斜检测
-- `resource_efficiency_analysis` - 资源效率分析（对比实际耗时与理论资源充足预期耗时）
-- `active_problem_finding` - 主动瓶颈分析
-
-**状态表优化** (6条规则):
-- `non_incremental_diagnosis` - 全量刷新原因诊断
-- `row_number_check` - ROW_NUMBER=1 pattern 检查
-- `append_only_scan` - Append-Only 表识别
-- `state_table_enable` - 状态表启用建议
-- `aggregate_reuse` - 聚合结果复用检查
-- `heavy_calc_state` - 高耗时 Calc 状态优化
-
-### Usage
-
-MCP Tool Call 示例
-
-#### 基本分析（仅 Stage/Operator 级别优化，默认）
-```json
-{
-  "name": "fetch_job_performance_data",
-  "arguments": {
-    "workspace_name": "your_workspace",
-    "job_id": "2026012808001805432z9g3fx1sok"
-  }
-}
-```
-
-如果结果是“未发现需要调整的参数”，则表示当前作业性能良好，无需进一步优化。
-
-#### quick 模式（默认，纯规则引擎，零 AI 消耗）
-```json
-{
-  "name": "fetch_job_performance_data",
-  "arguments": {
-    "workspace_name": "your_workspace",
-    "job_id": "2026012808001805432z9g3fx1sok"
-  }
-}
-```
-- 不传 `analysis_mode` 或传 `"quick"` 均为此模式
-- 纯规则引擎分析，不消耗 AI token，适合日常巡检和批量扫描
-- 输出内容：概况 + 参数建议 + 关键洞察（仅 `important` 级别，如资源效率分析）
-- 不输出 findings 详情和 detail 级别 insights（需要可切换 standard 模式）
-- 如果结果是"未发现需要调整的参数"且无关键洞察，表示当前作业性能良好
-
-#### Standard 模式（详细分析，规则引擎 + AI 研判数据）
-```json
-{
-  "name": "fetch_job_performance_data",
-  "arguments": {
-    "workspace_name": "your_workspace",
-    "job_id": "2026012808001805432z9g3fx1sok",
-    "analysis_mode": "detailed"
-  }
-}
-```
-
-#### Expert 模式（深度分析，需用户确认）
-```json
-{
-  "name": "fetch_job_performance_data",
-  "arguments": {
-    "workspace_name": "your_workspace",
-    "job_id": "2026012808001805432z9g3fx1sok",
-    "analysis_mode": "expert"
-  }
-}
-```
-
-**参数说明**：
-- `workspace_name` (必需): 工作空间名称
-- `job_id` (必需): 作业ID
-- `user_id` (可选): 用户ID，默认使用当前用户
-- `analysis_mode` (可选): 分析模式，默认 `quick`
-  - `quick` — 纯规则引擎，零 AI 消耗，适合日常巡检
-  - `detailed` — 规则引擎 + AI 研判数据（含 analysis_scope、stage_summary、全部 findings/insights），适合排查问题
-  - `expert` — 深度分析，按需加载 reference 文档，消耗较多 token。返回 `requires_confirmation=true` 和 `token_estimate`
-
-**分析模式说明**：
-- `quick`（默认）：与现有行为完全一致，findings 过滤掉 INFO/LOW 级别，insights 仅输出 important 级别
-- `detailed`：输出全部 findings/insights + analysis_scope（规则引擎中间计算数据），附带 AI 研判 prompt
-- `expert`：在 detailed 基础上，根据 findings 类型自动加载对应的 reference 文档（如 stage-operator-optimization.md、state-table-optimization.md），供 AI 做深度根因分析和优化方案设计
-
-**工具功能**：
-1. 自动获取job plan和job profile数据
-2. 调用性能分析器进行分析
-3. 返回优化建议和诊断结果
-
-
-### 用户意图映射
-
-当 AI 调用此工具时，根据用户的自然语言严格按关键词选择分析模式（不要自行升级）：
-
-1. **quick 模式**（默认，纯规则引擎）— 用户没有明确要求"详细"或"专家"时一律用 quick：
-   - "帮我分析 job xxx"
-   - "快速看看 job xxx 有没有问题"
-   - "给出任务 xxx 的优化建议"
-   - "再分析下这个 job"
-
-2. **detailed 模式**（详细分析，仔细分析，规则引擎 + AI 研判）— 仅当用户说"详细"或"仔细"时：
-   - "帮我详细分析 job xxx"
-   - "再详细分析下这个 job"
-   - "仔细看看 job xxx 的性能问题"
-
-3. **expert 模式**（专家分析，需用户确认 token 消耗）— 仅当用户原话包含"专家模式"、"深度分析"或"全面分析"时：
-   - "用专家模式分析 job xxx"
-   - "深度分析 job xxx"
-   - "帮我全面分析 job xxx"
-   - ⚠️ 注意："详细分析"是 detailed，不是 expert
-
-3. **不适用场景（禁止触发本 skill）**：
-   - "OPTIMIZE test_schema.test_vector_batch_1773819304920;"
-   - "OPTIMIZE sql帮我手动执行一下"
-   - 以上属于 SQL 执行请求，不是 Job 性能诊断，请走 SQL 执行工具
-
-**⚠️ 重要说明**：
-- 优化参数推荐必须遵守的原则 `references/optimization-principles.md`

-# Job 性能分析核心规范
-
-本文档定义 Job 性能分析的核心流程和原则。
-
-## 1. 输入说明
-
-**输入文件**：
-- `plan.json` - **必需**，执行计划（DAG、Operator、算法类型）
-- `job_profile.json` - **可选**，运行时统计（耗时、数据量、DOP）
-
-**关键原则**：
-- 完整分析需要两者结合
-- 仅从 profile 无法判断算法（如 Join 类型）
-- 仅从 plan 无法获取实际性能
-- **当 job_profile.json 为空或不提供时**：
-  - 部分分析（如增量状态表优化）仍可基于 plan.json 给出结果
-  - 涉及运行时性能数据的分析将无法执行
-  - 建议提供完整文件以获得最佳诊断效果
-
-## 2. 初始化步骤
-
-### 2.1 SQL 分类
-```python
-sql_text = plan['settings']['cz.sql.text']
-is_refresh = 'REFRESH' in sql_text.upper()
-```
-
-### 2.2 版本信息
-```python
-version = plan['build_info']['GitBranch']
-# ⚠️ 内部使用，不暴露给用户
-```
-
-### 2.3 VC 模式
-```python
-is_ap = plan['settings']['cz.inner.is.ap.vc'] == '1'
-# 0 = GP, 1 = AP
-
-# 获取 VC core 数
-if is_ap:
-    vc_cores = int(plan['settings']['cz.analyze.instance.executor.count'])
-else:
-    vc_cores = int(plan['settings']['cz.sql.gp.vc.capability']) // 100
-```
-
-### 2.4 已有参数
-```python
-settings = plan['settings']
-# ✅ 推荐前必须检查参数是否已存在
-# ❌ 不要推荐已存在且正确的参数
-```
-
-### 2.5 Stage 对齐
-```python
-for stage_id in plan['dml']['stages']:
-    if stage_id in profile['stageSummary']:
-        # 对齐成功
-```
-
-### 2.6 Operator 统计
-计算每个 operator：
-- 最大/平均耗时
-- Stage 占比
-- 总体占比
-- 倾斜比率（max/avg）
-
-### 2.7 选择分析策略
-
-根据 SQL 类型选择：
-- REFRESH → 错误分析（8） + 增量计算优化（4.1 + 4.2）
-- Compaction → TODO
-- GP job → TODO
-- AP job → TODO
-
-## 3. 核心原则
-
-### ❌ 禁止行为
-1. 不给无依据的参数
-2. 不凭空编造 flag
-3. 不推荐已存在且正确的参数
-4. 不说"没有发现问题"
-
-### ✅ 必须做到
-1. 每个建议必须有明确触发条件
-2. 每个建议必须有数据证据
-3. 推荐前必须检查参数是否已存在
-4. 必须主动分析所有慢 Stage
-
-## 4. 参数推荐逻辑
-
-```python
-def should_recommend(param_name, expected_value):
-    if param_name not in settings:
-        return True  # 参数不存在，推荐
-    
-    if settings[param_name] != expected_value:
-        return True  # 参数存在但值不对，推荐
-    
-    return False  # 参数已正确配置，不推荐
-```
-
-## 5. 输出格式
-
-### 必须包含
-- 发现的问题（附数据证据）
-- 参数建议（仅当问题存在）
-- 推理过程（引用实际数据）
-
-### 不要包含
-- 已配置的参数
-- 无依据的建议
-- 版本信息
-- 过度解释
-
-## 6. 工作流总结
-
-```
-输入 plan.json + job_profile.json
-  ↓
-初始化（2.1-2.7）
-  ↓
-选择策略
-  ↓ (REFRESH SQL)
-8. 错误分析（Job 冲突检测等）
-  ↓
-4.1 Stage/Operator 优化（8个子规则）
-  ↓
-4.2 状态表优化（7个子规则）
-  ↓
-生成报告（仅包含有依据的建议）
-```

-#### 提取 Profiling 数据
-```python
-# 从 job_profile.json 提取
-profiling_data = profile_data['data']['jobSummary']['jobProfiling']['profiling']
-
-# 构建时间映射
-profiling_map = {}
-for entry in profiling_data:
-    event_id = int(entry['e'])
-    timestamp_ms = int(entry['t'])
-    profiling_map[event_id] = timestamp_ms
-
-# 示例数据结构:
-# [
-#   {"e": 100.0, "t": "1769626801341"},  # RECEIVE_SUBMIT
-#   {"e": 101.0, "t": "1769626801341"},  # PRECHECK_START
-#   {"e": 102.0, "t": "1769626801343"},  # PRECHECK_END
-#   ...
-# ]
-```
-
-#### 计算各阶段耗时
-```python
-def calculate_phase_durations(profiling_map):
-    """计算各阶段耗时（毫秒）- 按照官方定义"""
-    durations = {}
-    
-    # 1. Setup: SQL初始化阶段 (100 -> 108)
-    if 100 in profiling_map and 108 in profiling_map:
-        durations['setup'] = profiling_map[108] - profiling_map[100]
-    
-    # 2. Resuming Cluster: 启动VC (110 -> 112)
-    if 110 in profiling_map and 112 in profiling_map:
-        durations['resuming_cluster'] = profiling_map[112] - profiling_map[110]
-    
-    # 3. Queued: 等待资源 (112 -> 120)
-    if 112 in profiling_map and 120 in profiling_map:
-        durations['queued'] = profiling_map[120] - profiling_map[112]
-    
-    # 4. Running: SQL处理数据 (120 -> 130)
-    if 120 in profiling_map and 130 in profiling_map:

-        durations['total'] = profiling_map[150] - profiling_map[100]
-    
-    return durations
-
-# 使用示例
-durations = calculate_phase_durations(profiling_map)
-running_time_ms = durations.get('running', 0)
-running_time_sec = running_time_ms / 1000
-```
-
-#### 关键阶段说明
-
-根据官方定义，Job 生命周期分为以下几个关键阶段：
-
-1. **Setup (100→108)**: SQL初始化阶段，包含编译优化等操作
-   - 正常情况下应该很快（< 2s）
-   - 如果耗时较长，可能是SQL过于复杂
-
-2. **Resuming Cluster (110→112)**: 等待启动VC
-   - 正常情况下应该很快（< 1s）
-   - 如果长时间未拉起，请联系技术支持
-
-3. **Queued (112→120)**: 作业排队等待资源
-   - 正常情况下应该很快（< 5s）
-   - 如果耗时较长，建议查看vc资源是否占满，考虑扩容vc
-
-4. **Running (120→130)**: SQL处理数据时间
-   - 这是核心计算阶段，通常占总时间的大部分
-   - 可以点到诊断查看每个算子耗时
-
-5. **Finish (130→150)**: SQL结束时间
-   - 包含commit数据、auto merge等操作
-   - 正常情况下应该较快
-
-#### 实际案例分析

-
-for stage_id, stage_data in profile['stageSummary'].items():
-    # 时间

-    # IO 统计
-    io = stage_data['inputOutputStats']
-    input_bytes = int(io['inputBytes'])
-    output_bytes = int(io['outputBytes'])
-    spill_bytes = int(io['spillingBytes'])
-```
-
-### Operator 统计
-```python
-# Operator 性能
-for op_id, op_data in stage_data['operatorSummary'].items():
-    # 耗时
-    wall_time = op_data['wallTimeNs']
-    max_ns = int(wall_time['max'])
-    avg_ns = int(wall_time['avg'])
-    
-    max_ms = max_ns / 1_000_000
-    avg_ms = avg_ns / 1_000_000
-    
-    # 倾斜比率
-    skew = max_ms / avg_ms if avg_ms > 0 else 1.0
-    
-    # Spilling
-    if 'spillStats' in op_data:
-        spill = op_data['spillStats']
-        # 详细的 spill 信息
-```
-
-## 常用计算模式
-
-### 计算占比
-```python
-# Stage 占总体百分比
-stage_pct = (stage_elapsed_ms / total_job_time) * 100
-
-# Operator 占 Stage 百分比
-op_pct = (op_max_ms / stage_elapsed_ms) * 100
-```
-
-### 判断触发条件
-```python
-# 耗时阈值
-is_slow = elapsed_ms > 12000 or (elapsed_ms / total_time * 100) > 15
-
-# DOP 差异
-dop_ratio = current_dop / upstream_dop
-is_dop_diff = dop_ratio < 0.5
-
-# 数据量阈值
-data_gb = bytes / (1024**3)
-is_large = data_gb > 10
-```
-
-### 搜索 Pattern
-```python
-# 使用 JSON 字符串搜索
-plan_str = json.dumps(stage)
-
-# Join 算法
-is_broadcast = 'BroadcastHashJoin' in plan_str or 'Broadcast' in plan_str
-is_shuffle = 'ShuffleHashJoin' in plan_str
-
-# Aggregate 阶段
-has_p1 = 'P1' in plan_str or 'PARTIAL1' in plan_str
-is_complete = 'COMPLETE' in plan_str
-
-# 高成本函数
-has_expensive = any(f in plan_str for f in 
-    ['MULTI_RANGE_COLLECT', '_DF_BF_COLLECT', 'BF_COLLECT'])
-
-# TableSink
-has_tablesink = 'TableSink' in plan_str
-is_overwrite = 'OVERWRITE' in plan_str
-is_delta = 'PhysicalTableSink_DELTA' in plan_str
-```
-
-## 典型分析示例
-
-### 找瓶颈 Operator
-```python
-# 按耗时排序
-sorted_ops = sorted(operator_analysis, 
-                   key=lambda x: x['max_time_ms'], 
-                   reverse=True)
-
-bottleneck = sorted_ops[0]
-```
-
-### 计算上游 DOP
-```python
-upstream_dops = [
-    stage_metrics[sid]['dop'] 
-    for sid in stage_metrics 
-    if sid != current_stage_id
-]
-max_upstream_dop = max(upstream_dops) if upstream_dops else 0
-```
-
-### 检查参数是否已存在
-```python
-def should_recommend(param, value):
-    if param not in settings:
-        return True
-    if settings[param] != value:
-        return True
-    return False
-```
-
-## 常见陷阱
-
-### ❌ 错误做法
-```python
-# 仅从 profile 判断 Join 类型
-# profile 中没有算法信息！
-join_type = ???  # 无法获取
-
-# 忽略参数检查
-optimizations.append(...)  # 可能重复推荐
-```
-
-### ✅ 正确做法
-```python
-# 从 plan 获取算法
-plan_str = json.dumps(stage['operators'])
-is_broadcast = 'BroadcastHashJoin' in plan_str
-
-# 从 profile 获取性能
-elapsed = stage_data['endTime'] - stage_data['startTime']
-
-# 检查参数
-if 'cz.optimizer.enable.broadcast.hash.join' not in settings:
-    recommend(...)
-```

-# 错误分析规范
-
-本文档定义 Job 错误分析的规则和处理方法。
-
-## 8. 报错分析
-
-### 8.0 错误信息收集器
-
-**目标**：统一从 job_profile.json 的所有 message 字段收集错误信息，去重并精炼，为后续错误分析提供基础。
-
-#### 设计原则
-
-1. **统一收集**：从 Job、Stage、Task 三个层级收集所有错误信息
-2. **去重精炼**：可能有重复的错误信息，需要去重和精炼
-3. **分类标注**：对错误信息进行分类（冲突、超时、内存等）
-4. **基础服务**：为后续的具体错误分析规则（如 8.1）提供数据基础
-
-#### 收集位置
-
-1. **Job 级别**：`data.jobStatus.message`
-2. **Stage 级别**：`data.jobSummary.stageSummary[stage_id].message`
-3. **Task 级别**：`data.jobSummary.stageSummary[stage_id].taskSummary[task_id].message`
-
-#### 错误识别
-
-通过关键字识别错误信息：
-- error, exception, failed, failure
-- conflict, timeout, abort, cancel
-- invalid, illegal, denied, forbidden
-- out of memory, oom, overflow
-- not found, unauthorized
-
-#### 去重策略
-
-- 使用消息内容作为去重 key
-- 完全相同的消息只保留第一个
-- 保留原始消息和精炼后的消息
-
-#### 输出格式
-
-```python
-{
-    'error_messages': [
-        {
-            'location': 'job_status' | 'stage' | 'task',
-            'stage_id': 'xxx',  # 如果是 stage/task 级别
-            'task_id': 'xxx',   # 如果是 task 级别
-            'message': '原始消息',
-            'refined_message': '精炼后的消息（截断过长内容）',
-            'raw_message': '完整原始消息'
-        }
-    ]
-}
-```
-
-#### 存储到 Context
-
-收集的错误信息存储到 `context['error_messages']`，供后续规则使用：
-- `context['error_messages']`：精炼后的错误列表
-- `context['raw_error_messages']`：原始错误列表
-
-#### Insight 输出
-
-```
-收集到 X 条错误信息（去重后 Y 条），涉及 Z 个位置。
-错误类型: 冲突错误, 超时错误, ...
-```
-
-### 8.1 提交冲突报错检测
-
-**目标**：基于 ErrorMessageCollector 收集的错误信息，检测提交冲突错误并给出重跑建议。
-
-#### 依赖关系
-
-此规则依赖于 ErrorMessageCollector（8.0），必须在错误收集器之后执行。
-
-#### 检测逻辑
-
-从 `context['error_messages']` 中查找包含以下特征的错误信息：
-
-```
-"this job has conflicts with another concurrent job which updates"
-```
-
-#### 数据来源
-
-不直接访问 job_profile.json，而是使用 ErrorMessageCollector 收集的错误信息：
-
-```python
-error_messages = context.get('error_messages', [])
-for error in error_messages:
-    if 'conflicts with another concurrent job which updates' in error['message'].lower():
-        # 检测到冲突
-```
-
-#### 输出结果
-
-**Finding**:
-- type: `job_conflict_error`
-- severity: `high`
-- title: "Job 提交冲突错误"
-- description: 详细的冲突信息，包括所有发现冲突的 Stage 和 Task
-- evidence: 冲突详情列表
-
-**Recommendation**:
-- type: `rerun_job`
-- priority: `high`
-- title: "重新运行整个 Job"
-- description: 建议重新提交并运行此 Job
-- action: "重新提交并运行此 Job"
-
-**Insight**:
-- category: `error_analysis`
-- message: 冲突统计信息和原因说明
-
-#### 解决方法
-
-**唯一解决方案**：重新运行整个 Job
-
-**原因说明**：
-- 提交冲突通常发生在多个 Job 并发更新同一张表时
-- 系统无法自动解决此类冲突
-- 重跑可以让 Job 在新的时间点重新执行，避免冲突
-
-#### 实现要点
-
-1. **依赖关系**：必须在 ErrorMessageCollector 之后执行
-2. **数据来源**：从 `context['error_messages']` 获取数据，不直接访问 profile
-3. **优先级**：错误分析应在其他优化分析之前执行
-4. **清晰性**：输出应明确指出错误发生的位置（Job Status / Stage / Task）
-5. **架构优势**：
-   - 解耦：冲突检测不需要知道数据结构细节
-   - 复用：其他错误分析规则也可以使用收集的错误信息
-   - 扩展：新增错误类型只需添加新规则，不需要重复收集逻辑
-
-#### 代码示例
-
-```python
-class JobConflictDetection(BaseRule):
-    """检测 Job 提交冲突错误"""
-    
-    name = "job_conflict_detection"
-    category = "error_analysis"
-    
-    def analyze_global(self, context: Dict) -> Dict:
-        # 从 context 中获取收集的错误信息
-        error_messages = context.get('error_messages', [])
-        
-        # 查找冲突错误
-        conflict_errors = []
-        for error in error_messages:
-            message = error.get('message', '')
-            if 'conflicts with another concurrent job which updates' in message.lower():
-                conflict_errors.append(error)
-        
-        # 生成 findings 和 recommendations
-        if conflict_errors:
-            # 构建详细的错误信息
-            # ...
-```
-
-#### 注意事项
-
-1. **不要过度分析**：发现冲突后，直接建议重跑，不需要深入分析冲突原因
-2. **不要给其他建议**：对于冲突错误，重跑是唯一解决方案，不要给出其他优化建议
-3. **检查 profile 数据**：如果 job_profile.json 为空或无效，跳过此规则
-4. **大小写不敏感**：检查时使用 `.lower()` 确保不遗漏任何格式的错误信息
-
-## 未来扩展
-
-后续可以添加更多错误分析规则，都基于 ErrorMessageCollector 收集的错误信息：
-
-### 8.2 内存溢出错误（OOM）
-- 检测关键字：`out of memory`, `oom`
-- 解决方案：增加内存配置、优化数据倾斜
-
-### 8.3 超时错误
-- 检测关键字：`timeout`
-- 解决方案：增加超时时间、优化查询性能
-
-### 8.4 权限错误
-- 检测关键字：`denied`, `forbidden`, `unauthorized`
-- 解决方案：检查权限配置
-
-### 8.5 数据格式错误
-- 检测关键字：`invalid`, `illegal`, `format`
-- 解决方案：检查数据格式、修复数据
-
-### 架构优势
-
-所有错误分析规则共享同一个错误收集器：
-1. **统一收集**：ErrorMessageCollector 统一收集所有错误
-2. **按需分析**：各个具体规则从收集的错误中筛选自己关心的类型
-3. **易于扩展**：新增错误类型只需添加新规则，不需要修改收集逻辑
-4. **性能优化**：只遍历一次 profile 数据，所有规则共享结果
-
-### 规则模板
-
-```python
-class NewErrorDetection(BaseRule):
-    """检测新类型错误"""
-    
-    name = "new_error_detection"
-    category = "error_analysis"
-    
-    def analyze_global(self, context: Dict) -> Dict:
-        # 从 context 获取收集的错误
-        error_messages = context.get('error_messages', [])
-        
-        # 筛选特定类型的错误
-        target_errors = [
-            error for error in error_messages
-            if 'keyword' in error['message'].lower()
-        ]
-        
-        # 生成 findings 和 recommendations
-        # ...
-```
-
-每个错误类型应该：
-1. 有明确的检测逻辑（关键字匹配）
-2. 给出具体的解决方案
-3. 提供足够的上下文信息
-4. 按照统一的输出格式
-5. 基于 ErrorMessageCollector 的结果
-
-## 已实现的错误分析规则
-
-### 8.1 提交冲突错误检测（JobConflictDetection）
-
-**关键字**：`conflicts with another concurrent job which updates`
-
-**解决方案**：重新运行整个 Job
-
-**输出**：
-- Finding: job_conflict_error
-- Recommendation: rerun_job (type)
-
-### 8.2 优化器错误检测（OptimizerErrorDetection）
-
-**关键字**：`optimizer internal error`
-
-**解决方案**：
-1. 如果未设置 `cz.sql.playback.scratch=true`，建议设置此参数
-2. 重新运行 Job 生成 playback 信息
-3. 收集 playback 信息用于问题诊断
-
-**输出**：
-- Finding: optimizer_internal_error
-- Recommendation: 设置 cz.sql.playback.scratch=true (parameter type)
-
-**特殊处理**：
-- 检查 settings 中是否已设置 playback 参数
-- 如果已设置，不重复推荐，但提示收集 playback 信息
-
-**代码示例**：
-```python
-class OptimizerErrorDetection(BaseRule):
-    def analyze_global(self, context: Dict) -> Dict:
-        error_messages = context.get('error_messages', [])
-        optimizer_errors = [
-            e for e in error_messages
-            if 'optimizer internal error' in e['message'].lower()
-        ]
-        
-        if optimizer_errors:
-            settings = context.get('settings', {})
-            playback_enabled = settings.get('cz.sql.playback.scratch', '').lower() == 'true'
-            
-            if not playback_enabled:
-                # 推荐设置 playback 参数
-                recommendations.append({
-                    'type': 'parameter',
-                    'setting': 'cz.sql.playback.scratch',
-                    'value': 'true',
-                    'priority': 'high',
-                    'impact': 'DIAGNOSTIC',
-                    'reason': '生成 playback 信息以帮助定位优化器问题'
-                })
-```

-# 增量算法分析指南
-
-本文档包含增量计算的算法识别和分析规则。
-
-这是增量优化的核心部分，用于识别和分析增量算法，为状态表优化提供基础。
-
-**相关文档**：
-- [Stage/Operator 优化](./stage-operator-optimization.md) - Stage 和 Operator 级别优化
-- [状态表优化](./state-table-optimization.md) - 状态表相关优化规则（依赖本文档的分析结果）
-- [优化原则](./optimization-principles.md) - 参数推荐原则
-
----
-
-## 状态表优化前提
-
-**⚠️ 重要：启用条件**
-
-状态表优化分析**默认禁用**，只有在以下情况下才会执行：
-- 用户在 prompt 中**明确提到**需要"状态表优化"
-- 命令行使用 `--enable-state-table` 参数
-
-**原因**：根据 prompt 4.2.0 的要求，如果用户没有提到使用状态表优化，则不需要使用下面的优化原则来优化。
-
-**使用方式**：
-```bash
-# 禁用状态表分析（默认）
-cz-analyze-job plan.json job_profile.json
-
-# 启用状态表分析
-cz-analyze-job plan.json job_profile.json --enable-state-table
-```
-
-**Claude Skill 使用**：
-- 基本分析："分析这两个文件的性能问题"
-- 包含状态表优化："分析这两个文件的性能问题，包括状态表优化"

-## 增量算法分析
-
-### 4.2.1 判断是否增量刷新及增量算法分析
-
-**目的**：确认当前 job 是否为增量刷新，并识别增量算法
-
-本节包含四个子步骤（4.2.1.1-4.2.1.4），对应增量算法的完整分析流程。
-
-#### 4.2.1.1 识别所有 operator 是 delta 还是 snapshot
-
-**第一步：判断是否增量刷新**
-使用 **4.1.1** 的方法判断。
-
-**第二步：识别增量数据**（仅当是增量 plan 时）
-如果是增量计算的 plan，需要收集哪些表是增量数据，哪些是读 snapshot。
-
-**数据提取**：
-```python
-# 从 TableScan operator 中获取 incrementalTableProperty
-table_scan = operator['tableScan']
-incr_property = table_scan.get('incrementalTableProperty', {})
-from_version = incr_property.get('from')
-to_version = incr_property.get('to')
-```
-
-**版本号含义**：
-
-`incrementalTableProperty` 有 `from/to` 字段，记录了版本范围：
-
-| from | to | 含义 | 说明 |
-|------|-----|------|------|
-| 28800 | 57600 | **Delta 数据** | 从版本 28800 到 57600 的增量数据 |
-| -9223372036854775808 | 28800 | **上个 Snapshot** | 版本 28800 的完整状态（上个状态） |
-| -9223372036854775808 | 57600 | **当前 Snapshot** | 版本 57600 的完整状态（当前状态） |
-
-**判断规则**（根据 original_prompt.md 第 49 行）：
-- **Delta 数据**：只有当 `from` 和 `to` 都是非 MIN_LONG 值时（如 `from=28800, to=57600`）
-- **Snapshot 数据**：`from=-9223372036854775808`（MIN_LONG）是明显特征
-
-**增量计算公式**：
-```
-上个 Snapshot (from=-9223372036854775808, to=28800) + Delta (from=28800, to=57600) = 当前 Snapshot (from=-9223372036854775808, to=57600)
-```
-
-**示例**：
-```python
-# 示例 1: Delta 数据
-{
-  "from": "28800",
-  "to": "57600",
-  "fromMetaVersion": "0",
-  "toMetaVersion": "0"
-}
-# → 这是从 28800 到 57600 的增量数据（from 和 to 都不是 MIN_LONG）
-
-# 示例 2: 上个 Snapshot
-{
-  "from": "-9223372036854775808",
-  "to": "28800",
-  "fromMetaVersion": "0",
-  "toMetaVersion": "0"
-}
-# → 这是版本 28800 的完整状态（from 是 MIN_LONG）
-
-# 示例 3: 当前 Snapshot
-{
-  "from": "-9223372036854775808",
-  "to": "57600",
-  "fromMetaVersion": "0",
-  "toMetaVersion": "0"
-}
-# → 这是版本 57600 的完整状态（from 是 MIN_LONG）
-```
-
-**第三步：Delta/Snapshot 传播规则**
-
-通过分析算子的输入输出，自动推导每个算子处理的是 delta 还是 snapshot 数据。
-
-**传播规则**：
-
-1. **一元算子**（Filter, Project, Calc 等）：
-   - 输入是 delta → 输出是 delta
-   - 输入是 snapshot → 输出是 snapshot
-   ```
-   Filter(delta) = delta
-   Filter(snapshot) = snapshot
-   ```
-
-2. **Join 算子**：
-   - **只有** left 和 right **都是 snapshot**，结果才是 snapshot
-   - 其他情况（有任何一个是 delta）结果都是 delta
-   ```
-   Join(snapshot, snapshot) = snapshot
-   Join(delta, snapshot) = delta
-   Join(snapshot, delta) = delta
-   Join(delta, delta) = delta
-   ```
-
-3. **Union 算子**：
-   - 所有输入都是 snapshot → 输出是 snapshot
-   - 所有输入都是 delta → 输出是 delta
-   - 部分 delta，部分 snapshot → 输出是 snapshot（但这种情况很少见）
-   ```
-   Union(snapshot, snapshot, ...) = snapshot
-   Union(delta, delta, ...) = delta
-   ```
-
-4. **其他多元算子**：
-   - 一般按照 Union 规则处理
-   - 如果遇到特殊情况，需要单独分析
-
-5. **⚠️ 增量算法 Hint 优先规则**（重要补充）：
-   - **如果算子有增量算法 hint**（如 `IncrementalJoinRule`, `IncrementalAggregateRule` 等），**该算子应该被标记为 delta**
-   - 这是因为增量算法是用来处理增量数据的，即使输入是 snapshot，增量算法也会输出 delta
-   - **增量算法的语义**：可以接受 SNAPSHOT 输入并产生 DELTA 输出（通过比较两个 snapshot 计算差异）
-   - **检查方法**：在算子的 JSON 中查找 `Incremental` 或 `DeltaState` 关键字
-   - **优先级**：增量 hint 检查应该在基于输入的传播规则之前执行
-
-   ```python
-   # 示例：HashJoin 有增量 hint
-   if 'Incremental' in json.dumps(operator) or 'DeltaState' in json.dumps(operator):
-       operator_type = DataType.DELTA  # 直接标记为 delta
-   else:
-       # 使用基于输入的传播规则
-       operator_type = infer_from_inputs(...)
-   ```
-
-   **实际案例**：
-   ```
-   HashJoin30 (有 IncrementalJoinWithoutCondenseRule hint)
-   ├── ShuffleRead31 → SNAPSHOT (来自 snapshot TableScan)
-   └── ShuffleRead92 → DELTA (来自 delta TableScan)
-
-   结果：HashJoin30 = DELTA（因为有增量 hint，而不是基于输入判断）
-   ```
-
-#### 4.2.1.2 识别不同算子的增量算法
-
-**目的**：识别不同算子的增量算法，区分真正的 join/aggregate/window 增量算子和算法的一部分
-
-##### Rule Hint 解析
-
-增量算法会在算子上添加 Rule hint，用于标识算子属于哪个增量算法。
-
-**Rule Hint 格式**：
-
-1. **不带 ID 的 Rule**：
-   ```
-   Rule:IncrementalLinearFunctionAggregateRule
-   ```
-   - 表示这是增量 Aggregate 算法的一部分
-   - Rule 名称包含算子类型（Aggregate/Join/Window）
-
-2. **带 ID 的 Rule**：
-   ```
-   Rule:IncrementalJoinWithoutCondenseRule_cz::optimizer::LogicalJoin#31766417
-   ```
-   - `LogicalJoin#31766417` 是算子 ID
-   - 所有带相同 ID 的算子都是为了计算同一个 Join 的增量算法
-   - 用于识别增量算法的边界
-
-3. **HINT= 格式（新增，包含 DeltaState 信息）**：
-   ```
-   HINT=delta,DeltaState:[1,1896] - [1,6393]_IncrementalWindowSetDeltaRule#cz::optimizer::Window#293342
-   ```
-   - `HINT=delta` 表示计算 delta 数据来优化
-   - `DeltaState:[1,1896] - [1,6393]` 表示该算子是整体增量算法的状态算子
-   - `IncrementalWindowSetDeltaRule` 是使用的增量算法
-   - `Window#293342` 表示是对哪个算子计算了增量算法
-   - 这种 hint 提供了更详细的状态信息，用于识别增量算法的状态边界
-
-4. **⚠️ DeletePlan Rule（必须作为边界终止遍历）**：
-   ```
-   Rule:DeletePlan-delta-join(left)_Delta:L_Snapshot:R
-   ```
-   - **DeletePlan 相关的 hint 不属于任何增量算法**
-   - 这些 hint 用于表示删除数据的 plan
-   - **在识别增量算法时的处理**：
-     - **解析阶段**：过滤掉所有包含 `DeletePlan` 的 Rule hint（不作为算法起点）
-     - **遍历阶段**：如果在执行路径中遇到 DeletePlan 算子，**必须终止遍历**
-   - **为什么必须终止而不是跳过**：
-     - DeletePlan 算子在执行路径中表示删除操作
-     - 如果跳过 DeletePlan 继续查找，找到的 subplan 会缺少中间算子（不完整）
-     - 由于 plan 是执行路径不能跳过，所以遇到 DeletePlan 必须终止
-
-**Rule Hint 的作用**：
-
-- **识别算法类型**：从 Rule 名称判断是 Aggregate/Join/Window 算法
-- **识别算法边界**：通过 ID 找到属于同一个算法的所有算子
-- **区分原始算子**：
-  - 如果 Rule 出现在对应类型的算子上（如 Aggregate Rule 在 Aggregate 算子上）→ 原始 SQL 算子
-  - 如果 Rule 出现在其他类型的算子上（如 Aggregate Rule 在 Join 算子上）→ 算法辅助算子
-- **处理 DeletePlan 算子**：
-  - **解析阶段**：包含 `DeletePlan` 的 Rule hint 不作为算法起点
-  - **遍历阶段**：遇到 DeletePlan 算子作为边界条件，终止遍历
-
-#### 4.2.1.3 算子增量算法对应的 subplan
-
-**目的**：找到一个增量算法对应的所有算子，识别算子对应的 root 阶段
-
-**⚠️ 重要说明**：
-
-1. **完整的执行 subplan，不是零散的 hint operator**：
-   - 算子增量算法对应的 subplan **不是**让你把 rule 相同的合在一起
-   - rule 相同的算子肯定来源于同一个算子对应的增量算法
-   - 而是要把某一个增量算法涉及到的**所有算子**都包含起来
-   - 这些算子**不一定有 Rule 这些 hint**
-   - 他们是一个执行的 subplan，而不是这些零散的 hint operator 组成
-
-   **示例**：
-   ```
-   假设有增量 Aggregate 算法：
-   - TableScan (delta) - 没有 Rule hint，但是算法的输入
-   - TableScan (snapshot) - 没有 Rule hint，但是算法的输入
-   - Join - 有 Rule hint（为 Aggregate 准备数据）
-   - Calc - 没有 Rule hint，但在算法执行路径中
-   - Aggregate (P1) - 有 Rule hint
-   - Aggregate (P2) - 有 Rule hint
-   - Aggregate (Final) - 有 Rule hint
-
-   完整 subplan 应该包含所有 7 个算子，而不仅仅是有 hint 的 4 个算子
-   ```
-
-2. **使用 plan.json 的实际 operator ID，不是数组索引**：
-   - 在 plan.json 里找到所有 operator 对应的 Id
-   - 注意这里的 **ID 不是代码中那些 index 下标**
-   - 应该使用 plan.json 中算子对象的 `"id"` 字段的实际值
-   - 例如：`"id": "12345"` 应使用 `"12345"` 而不是数组索引 `0`
-
-3. **⚠️ 处理没有 ID 的 Rule Hint（新增逻辑 - 两阶段方法）**：
-
-   根据 4.2.1.2 找到相同增量算法的算子后，需要采用**两阶段方法**来构建完整的 subplan：
-
-   **阶段1：构建初始确定集合（在 `_parse_rule_hints()` 中完成）**
-
-   目的：复用 4.2.1.2 的逻辑，找到所有带hint的算子（有ID和无ID），形成确定集合
-
-   **步骤 1.1：解析有ID的hint**
-   - 格式：`Rule:IncrementalAggregateSetDeltaRuleV2#5402883`
-   - 存储在 `self.rule_groups` 中：`{algorithm_id: [operator_indices]}`
-
-   **步骤 1.2：解析无ID的hint**
-   - 格式：`HINT=Rule:IncrementalAggregateSetDeltaRuleV2_Delta:R_Snapshot:L`
-   - 存储在 `self.operator_rule_names` 中：`{operator_index: rule_name}`
-
-   **步骤 1.3：匹配无ID的hint到算法**
-   - 调用 `_assign_hints_without_id_to_algorithms()`
-   - 对于每个无ID的hint，向下游查找匹配的算法
-   - **关键**：匹配条件是 **算子类型相同 AND rule名称相似**
-   - 使用 `_find_matching_algorithm_downstream_by_name()` 进行匹配：
-     - 提取基础rule名称（去除版本号V2等）
-     - BFS向下游搜索
-     - 找到第一个算子类型和rule名称都匹配的算法
-   - 将匹配的算子加入对应算法的 `rule_groups`
-
-   **阶段2：从确定集合扩展到完整subplan（在 `_identify_incremental_algorithms_with_subplan()` 中完成）**
-
-   目的：从确定集合（rule_groups）出发，使用边界规则遍历上下游，得到完整的subplan
-
-   **⚠️ 重要：使用两个独立的循环**
-
-   根据用户反馈："应该先全部遍历一遍增量算法，得到所有的确定性的相关subplan后，再继续后续操作"
-
-   **第一个循环：为所有算法构建确定集合**
-   - 遍历所有算法
-   - 对每个算法调用 `_connect_hint_operators_for_algorithm()`
-   - 找到所有hint算子之间的连通路径
-   - 存储所有算法的确定集合
-
-   **第二个循环：从确定集合扩展到完整subplan**
-   - 遍历所有算法
-   - 使用第一个循环构建的确定集合
-   - 调用 `_find_algorithm_subplan_from_confirmed_set()` 扩展
-   - 使用边界规则判断是否继续添加算子
-
-   **步骤 2.1：第一个循环 - 构建所有确定集合**
-   - 调用 `_connect_hint_operators_for_algorithm()` 为每个算法
-   - 找到所有hint算子之间的连通路径
-   - 根据 prompt："这些算子联通(遍历)起来的算子一定属于该算法的subplan一部分"
-   - 例如：如果有 hint 算子 A 和 D，且它们之间有路径 A→B→C→D，则 B 和 C 也属于确定集合
-   - 存储在 `all_confirmed_sets` 字典中
-
-   **步骤 2.2：第二个循环 - 扩展到完整subplan**
-   - 使用第一个循环构建的确定集合作为起点
-   - 这些算子已经包含了有ID和无ID的hint算子，以及它们之间的连通路径
-
-   **步骤 2.3：调用 `_find_algorithm_subplan_from_confirmed_set()`**
-   - 从确定集合的每个算子出发
-   - 向上游和下游遍历
-   - 使用边界规则判断是否继续添加算子
-
-   **步骤 2.4：得到完整subplan**
-   - 确定集合 + 扩展的算子 = 完整subplan
-   - 直到所有方向都遇到边界为止
-
-   **代码实现要点**：
-   ```python

-
-       return confirmed_set
-   ```
-
-   **重要性**：
-   - **两阶段方法确保了准确性**：先确定哪些算子肯定属于该算法，再扩展
-   - **处理无ID的hint**：通过向下游查找，将无ID的hint正确归属到对应算法
-   - **连通图保证完整性**：所有hint算子之间的路径都被包含，避免遗漏
-   - **边界规则控制范围**：从确定集合扩展时，边界规则防止跨算法包含
-
-##### 增量算法识别流程
-
-**自动识别步骤**：
-
-1. **识别 TableScan 数据类型**（4.2.1.1）
-   - 解析 `incrementalTableProperty` 的 from/to 字段
-   - 标记每个 scan 是 delta 还是 snapshot
-
-2. **解析 Rule Hints**（4.2.1.2）
-   - 提取所有 Rule hint
-   - **⚠️ 过滤 DeletePlan hint**：忽略所有包含 `DeletePlan` 的 Rule hint（不作为算法起点）
-   - 按照 Rule ID 分组算子
-   - 识别算法类型（Aggregate/Join/Window）
-
-3. **构建算子依赖关系**（4.2.1.3）
-   - 分析算子的输入输出关系
-   - 构建依赖图
-   - 使用 plan.json 的 "id" 字段表示每个算子的唯一 id
-
-4. **传播数据类型**（4.2.1.1）
-   - 从 TableScan 开始，按照传播规则推导每个算子的数据类型
-   - 迭代直到所有算子的类型都确定
-
-5. **识别增量算法边界**（4.2.1.2 & 4.2.1.3）
-   - 根据 Rule ID 分组找到每个增量算法的所有算子
-   - 区分原始 SQL 算子和算法辅助算子
-   - 找到每个增量算法的 root 算子（最上层算子）
-
-**示例**：
-
-假设有以下 plan：
-```
-TableScan(delta) → Join → Aggregate(P1) → Aggregate(P2) → Aggregate(Final)
-                     ↑
-TableScan(snapshot) ─┘
-```
-
-分析结果：
-- TableScan1: delta
-- TableScan2: snapshot
-- Join: delta（因为有一个输入是 delta）
-- Aggregate(P1): delta（输入是 delta）
-- Aggregate(P2): delta（输入是 delta）
-- Aggregate(Final): delta（输入是 delta）
-
-如果 Aggregate(P1/P2/Final) 都有 `Rule:IncrementalAggregateRule#12345`：
-- 这三个 Aggregate 都是为了计算同一个 Aggregate 的增量算法
-- 其中 Aggregate(Final) 是原始 SQL 的 Aggregate
-- Aggregate(P1/P2) 是算法辅助算子（3阶段聚合的中间阶段）
-
-##### 边界条件（重要）
-
-在查找增量算法的 subplan 时，必须设置严格的边界条件以避免跨算法包含。
-
-**⚠️ 关键区别**：不同边界条件对 subplan 的处理方式不同：
-- **排除边界**：不添加到 subplan，直接返回
-- **包含边界**：添加到 subplan，但终止遍历
-
-**边界条件**：
-
-1. **不同 hint 终止**（包含边界）：
-   - 碰到不是相同 hint 的算子，必须终止（避免将其他增量算法的算子包含进来）
-   - ✅ **添加到 subplan**，然后终止遍历
-
-2. **Aggregate Final/Complete 终止**（包含边界）：
-   - 对于 aggregate 算法，查找上游碰到 Final/Complete 状态也要终止（避免跨越算法边界）
-   - ✅ **添加到 subplan**，然后终止遍历
-
-3. **⚠️ DeletePlan 终止**（排除边界）：
-   - 如果遇到 DeletePlan 相关算子，必须终止遍历
-   - **原因**：DeletePlan 不属于任何增量算法
-   - **为什么不能跳过**：由于 plan 是执行路径，如果跳过 DeletePlan 继续查找，找到的 subplan 会缺少中间算子（不完整）
-   - ❌ **不添加到 subplan**，直接返回
-
-4. **⚠️ Snapshot 边界终止**（包含边界）：
-   - 向上游遍历时，如果当前算子是 snapshot 且上游也是 snapshot，必须终止遍历
-   - **原因**：snapshot 表示完整状态，其上游的 snapshot 不应该再属于增量算法一部分
-   - **为什么不能跳过**：由于 plan 是执行路径，如果跳过 snapshot 继续查找，找到的 subplan 会缺少中间算子（不完整）
-   - ✅ **添加到 subplan**，然后终止遍历
-   - **注意**：这个检查仅在向上游（输入）遍历时生效，向下游遍历不受影响
-
-5. **⚠️ Calc 边界终止**（包含边界）：
-   - 如果是 calc 有 hint，且 hint 包含了 DeltaState 和 Incremental，必须终止遍历
-   - **原因**：这种 calc 算子是某个增量算法的边界
-   - ✅ **添加到 subplan**，然后终止遍历
-
-6. **⚠️ DF Aggregate 终止**（排除边界）：
-   - 如果遇到 aggregate 算子，且聚集函数包括 MULTI_RANGE_COLLECT 或 _DF_BF_COLLECT，必须终止遍历
-   - **原因**：这是一个 DF (Dynamic Filter) 的 aggregate，仅仅是优化的一个 plan，不需要添加
-   - ❌ **不添加到 subplan**，直接返回
-   - **检查的聚集函数**：MULTI_RANGE_COLLECT, _DF_BF_COLLECT, DF_BF_COLLECT, BF_COLLECT
-
-##### 验证规则（重要）
-
-根据 prompt 4.2.1.3 第 60 行的要求，脚本会自动验证增量算法的正确性。这些验证规则用于检测脚本实现是否正确。
-
-**验证规则**：
-
-1. **算子唯一性**：同一个 operator 不应该属于两个不同的增量算法
-   - **例外**：root 节点或 TableScan 可以横跨多个增量算法
-   - **原因**：一个算子只能属于一个增量算法的执行路径（除了共享的输入源）
-
-2. **上下游冲突**：如果某个 operator 属于了上游的增量算法，就不应该属于下游的增量算法
-   - **原因**：增量算法的执行是有顺序的，算子不应该同时参与上下游的计算
-   - **例外**：TableScan 可以被多个算法共享
-
-3. **Snapshot 边界**：对于 snapshot 的算子，增量算法遍历时应该停止
-   - **原因**：snapshot 算子表示完整状态，其上游不应该再属于增量算法
-   - **检查**：如果算法包含 snapshot 算子，不应该继续向上游遍历到其他 snapshot 算子
-
-4. **DeletePlan 边界**：如果遇到 DeletePlan 算子，遍历应该已经终止
-   - **原因**：DeletePlan 不属于任何增量算法，不应该出现在增量算法的 subplan 中
-   - **检查**：如果增量算法的 subplan 包含 DeletePlan 算子，说明边界检测有问题
-
-5. **Top-Down 遍历检查**（根据 original_prompt.md 第 76 行）：从 root 节点开始 top-down 遍历，在碰到边界算子前不应该有其他增量算法的算子
-   - **原因**：如果在遍历路径中发现其他算法的算子，说明算法边界识别有问题
-   - **检查方法**：
-     - 从每个算法的 root 节点开始
-     - 向下游（输入方向）遍历
-     - 在遇到边界条件前，检查路径上的算子是否属于其他算法
-     - 如果有，说明算法识别有问题
-   - **边界条件**：与 subplan 查找时的边界条件一致（DeletePlan、不同 hint、Final/Complete、Snapshot 边界等）
-
-**验证警告输出**：
-
-如果检测到问题，脚本会在控制台输出验证警告：
-
-```
-[WARNING] 增量算法验证发现 4 个问题:
-  ⚠️  [算子唯一性] 算子 12345 属于 2 个不同的增量算法（非 root 节点且非 TableScan）: ...
-  ⚠️  [上下游冲突] 算子 67890 同时属于上游算法 IncrementalJoinRule#111 和下游算法 IncrementalAggregateRule#222
-  ⚠️  [Snapshot 边界] 算法 IncrementalAggregateRule#333 包含 snapshot 算子 op_100，但继续向上游遍历到 snapshot 算子 op_50
-  ⚠️  [Top-Down 遍历] 算法 IncrementalAggregateRule#444 从 root 节点遍历时，在碰到边界前发现算子 op_200 属于其他算法: IncrementalJoinRule#555
-```
-
-**重要提示**：
-
-- ⚠️ 这些是**验证规则**，不是告警
-- ⚠️ 如果不满足这些规则，说明**脚本有问题**，需要修改脚本实现
-- ⚠️ 验证警告表明增量算法识别逻辑可能存在错误，需要检查：
-  - `_find_algorithm_subplan_strict()` 的边界检测逻辑
-  - `_validate_algorithms()` 的验证逻辑
-  - 算子依赖关系的构建是否正确
-
-**代码位置**：
-
-验证逻辑实现在 `utils/incremental_algorithm_analyzer.py`：
-- `_validate_algorithms()` 方法：主验证入口，包含规则 1-4
-- `_validate_topdown_traversal()` 方法：规则 5 的实现（Top-Down 遍历检查）
-- `_topdown_traverse_and_check()` 方法：递归遍历并检查算子归属
-- `_is_boundary_operator()` 方法：判断边界条件
-
-##### TableScan Append-Only 信息收集
-
-**目的**：为每个增量算法收集所有 TableScan 算子的 append-only 信息
-
-根据 prompt 4.2.1.3.1 新增要求：
-> "每个增量算法得到了自己所有算子后，把所有tablescan算子找出来，
-> 如果全部是appendonly的tablescan，则显示出来，并标注；
-> 如果不全部是，也请显示每个tablescan是不是appendonly；
-> appendonly信息在4.2.1.5里已经得到，从这里拿"
-
-**实现方法**：
-
-在 `_identify_incremental_algorithms_with_subplan()` 方法中，为每个算法添加 `tablescan_append_only_info` 字段：
-
-```python
-def _collect_tablescan_append_only_info(self, subplan_indices: List[int]) -> Dict:
-    """
-    收集增量算法中所有 TableScan 算子的 append-only 信息
-

-    ]
-  }
-}
-```
-
-**显示格式**：
-
-在增量算法分析结果中，会显示每个算法的 TableScan 信息：
-
-```
-增量算法: IncrementalAggregateSetDeltaRuleV2#5399145 (aggregate)
-  算子数量: 15
-  TableScan 信息:
-    - 包含 TableScan: True
-    - 总数: 2
-    - Delta TableScan: 1
-    - ✅ 所有 delta TableScan 都是 append-only (1/1)
-      - TableScan#12345 (delta, append_only) ✅
-    - 另有 1 个 snapshot TableScan (不参与 append-only 判断)
-      - TableScan#12346 (snapshot, N/A)
-```
-
-或者如果不是全部 append-only：
-
-```
-增量算法: IncrementalJoinWithoutCondenseRule#5398716 (join)
-  算子数量: 20
-  TableScan 信息:
-    - 包含 TableScan: True
-    - 总数: 3
-    - Delta TableScan: 2
-    - ⚠️  部分 delta TableScan 是 append-only (1/2)
-      - TableScan#12347 (delta, append_only) ✅
-      - TableScan#12348 (delta, with_delete) ⚠️
-    - 另有 1 个 snapshot TableScan (不参与 append-only 判断)
-      - TableScan#12349 (snapshot, N/A)
-```
-
-**重要说明**：
-- **只有 delta 类型的 TableScan 才有 append-only 的概念**
-- snapshot 类型的 TableScan 不参与 append-only 判断
-- `all_append_only` 字段表示"所有 delta TableScan 是否都是 append-only"
-- 显示时会明确区分 delta 和 snapshot TableScan
-
-**应用场景**：
-
-这个信息可以用于：
-1. **Window 优化（4.2.3）**：检查 window 输入是否全部是 append-only
-2. **Aggregate 复用（4.2.6）**：检查 aggregate 输入是否全部是 append-only
-3. **状态表优化（4.2.5）**：判断是否需要创建状态表
-4. **增量算法分析**：了解增量算法的输入数据特性
-
-#### 4.2.1.4 展示增量算法以及显示查看增量算法的状态信息/状态图等
-
-**目的**：可视化增量算法的依赖关系，展示哪些算子计算 aggregate/join/window
-
-##### 增量算法可视化
-
-生成增量算法依赖关系图，包括：
-- 每个增量算法的类型（Aggregate/Join/Window）
-- 算法包含的算子列表
-- 算法之间的依赖关系
-- 执行顺序（从上到下）
-- Root 算子标识
-
-##### 应用场景
-
-**状态表优化规则使用**：
-
-**重要前提**：关于状态表这些优化必须是对应算子的对应增量算法，如 aggregate 则必须是增量算法产生的，join/window 等都类似；可以根据 4.2.1.2 来判断。
-
-1. **aggregate_reuse 规则**：
-   - 只检查原始 SQL 的 Aggregate
-   - 过滤掉算法辅助的 Aggregate（P1/P2 阶段）
-   - **必须检查 aggregate 是否有增量 hint**（根据 4.2.1.2）：
-     - 检查是否包含 `IncrementalLinearFunctionAggregateRule` 等 Rule hint
-     - 检查是否包含 `HINT=delta,DeltaState:...` 等新格式 hint
-     - 如果没有增量 hint，说明不是原始 SQL 的 aggregate，跳过
-
-2. **state_table_enable 规则**：
-   - 只为原始 SQL 的算子建议状态表
-   - 不为算法辅助算子建议状态表
-   - **必须验证算子属于增量算法**（根据 4.2.1.2）
-
-3. **其他规则**：
-   - 类似地区分 Join/Window 的原始算子和辅助算子
-   - 所有状态表优化都必须基于增量算法识别（4.2.1.2）
-
-#### 4.2.1.5 算子 delta 是否为 append-only（纯增）
-
-**目的**：判断 delta 数据是否为 append-only（纯增，没有删除），用于后续优化决策
-
-**判断规则**：
-
-1. **TableScan 算子**：
-   - 检查是否输出 `__incremental_deleted` 列（注意是过去式）
-   - 检查位置：算子的实际输出列（`operator.schema.structTypeInfo.fields`），而不是表定义的完整schema
-   - **如果输出** → delta 不是纯增（有删除）
-   - **如果没有输出** → delta 是纯增
-
-   ```python
-   # 获取算子实际输出的列
-   operator_schema = op.get('schema', {})
-   struct_info = operator_schema.get('structTypeInfo', {})
-   fields = struct_info.get('fields', [])
-
-   has_delete_col = any(f.get('name') == '__incremental_deleted' for f in fields)
-
-   if has_delete_col:
-       append_only_type = "with_delete"  # 有删除
-   else:
-       append_only_type = "append_only"  # 纯增
-   ```
-
-2. **Join 算子**：
-   - **优先检查 DeltaState 模式**（新增规则）：
-     - `DeltaState-` 表示有删除（非纯增）
-     - `DeltaState+` 表示纯增
-   - **如果没有 DeltaState 模式**，按以下逻辑：
-     - **情况1**：只有一路是 delta，且 join type 是 `inner/anti/left_semi`
-       - 继承该 delta 输入的 append-only 类型
-     - **情况2**：所有输入都是 delta，且 join type 是 `inner/left_semi/anti`
-       - **必须检查 Rule hint**：join 上必须有 Rule pattern（如 `Rule:IncrementalJoinWithoutCondenseRule`）
-       - 所有 delta 都是纯增且有 Rule hint 时，join 的 delta 才是纯增
-     - **其他情况**：默认为有删除
-
-   ```python
-   # 新增：优先检查 DeltaState 模式
-   op_str = json.dumps(op)
-   if 'DeltaState-' in op_str:
-       append_only_type = "with_delete"  # 有删除
-   elif 'DeltaState+' in op_str:
-       append_only_type = "append_only"  # 纯增
-   else:
-       # 原有逻辑
-       join_type = get_join_type(op)  # 从 hashJoin.join.type 路径提取
-       delta_inputs = [inp for inp in inputs if inp.data_type == 'delta']
-
-       if len(delta_inputs) == 1 and join_type in ['inner', 'anti', 'left_semi']:
-           # 继承该 delta 输入的 append-only 类型
-           append_only_type = delta_inputs[0].append_only_type
-       elif len(delta_inputs) == len(inputs) and join_type in ['inner', 'left_semi', 'anti']:
-           # 多 delta join：必须检查 Rule hint
-           if all(inp.append_only_type == 'append_only' for inp in delta_inputs) and has_rule_hint(op):
-               append_only_type = "append_only"
-           else:
-               append_only_type = "with_delete"
-       else:
-           append_only_type = "with_delete"
-   
-   def get_join_type(op):
-       """从 hashJoin.join.type 路径提取 join type"""
-       if 'hashJoin' in op and 'join' in op['hashJoin']:
-           return op['hashJoin']['join'].get('type', 'unknown').lower()
-       # 类似处理 nestedLoopJoin, broadcastHashJoin
-       return 'unknown'
-   
-   def has_rule_hint(op):
-       """检查是否有 Rule hint pattern"""
-       op_str = json.dumps(op)
-       return 'Rule:' in op_str
-   ```
-
-3. **Aggregate/Window 算子**：
-   - **优先检查 DeltaState 模式**（新增规则）：
-     - `DeltaState-` 表示有删除（非纯增）
-     - `DeltaState+` 表示纯增
-   - **如果没有 DeltaState 模式**：继承输入的 delta 是否纯增
-
-   ```python
-   # 新增：检查 DeltaState 模式
-   op_str = json.dumps(op)
-   if 'DeltaState-' in op_str:
-       append_only_type = "with_delete"  # 有删除
-   elif 'DeltaState+' in op_str:
-       append_only_type = "append_only"  # 纯增
-   else:
-       # 继承输入的 append-only 类型
-       # 只要有一路不是纯增，则该算子 delta 都不是纯增
-       if any(inp.append_only_type == 'with_delete' for inp in inputs):
-           append_only_type = "with_delete"
-       else:
-           append_only_type = "append_only"
-   ```
-
-   **DeltaState 模式示例**：
-   ```
-   HINT=delta,DeltaState-:[1,1896] - [1,6393]_IncrementalWindowSetDeltaRule#cz::optimizer::Window#44
-   ```
-   - `DeltaState-` 中的 `-` 表示有删除
-   - `DeltaState+` 中的 `+` 表示是纯增
-   - 所有 aggregate/join/window 都有类似 pattern
-
-4. **其他算子**：
-   - 把所有输入的 delta 一起看
-   - 只要有一路不是纯增，则该算子 delta 都不是纯增
-
-   ```python
-   # 过滤出 delta 输入
-   delta_inputs = [inp for inp in inputs if inp.data_type == 'delta']
-
-   # 只要有一路不是纯增，则不是纯增
-   if any(inp.append_only_type == 'with_delete' for inp in delta_inputs):
-       append_only_type = "with_delete"
-   else:
-       append_only_type = "append_only"
-   ```
-
-**应用场景**：
-
-- **4.2.3 Window 优化**：检查 window 输入是否是 append-only
-- **4.2.6 Aggregate 复用**：MIN/MAX 在 append-only 情况下应该使用之前的结果
-
-**⚠️ 新增规则总结**：
-
-**DeltaState 模式优先级最高**：
-- 对于 Join/Aggregate/Window 算子，优先检查 `DeltaState-` 或 `DeltaState+` 模式
-- 如果存在 DeltaState 模式，直接根据 `+/-` 符号判断是否纯增
-- 只有在没有 DeltaState 模式时，才使用原有的继承逻辑
-
-**模式示例**：
-```
-HINT=delta,DeltaState-:[1,1896] - [1,6393]_IncrementalWindowSetDeltaRule#cz::optimizer::Window#44
-HINT=delta,DeltaState+:[1,1896] - [1,6393]_IncrementalAggregateRule#cz::optimizer::Aggregate#123
-```
-
-**判断优先级**：
-1. **DeltaState 模式** → 直接判断（最高优先级）
-2. **原有逻辑** → 继承输入或检查 Rule hint（备用逻辑）

-## 参数推荐原则
-
-### ❌ 禁止行为
-
-1. **不要给没有依据的参数**
-2. **不要凭空给 flag**
-3. **不要推荐已存在且正确的参数**
-
-### ✅ 必须做到
-
-1. **仅在发现实际问题时才建议参数**
-2. **每个建议必须有明确的触发条件**
-3. **每个建议必须引用实际数据作为证据**
-4. **必须检查 settings 避免重复建议**
-
-### 📋 其他可能有用的参数
-
-对于那些**可能**有用但没有明确问题证据的参数：
-- 单独列出
-- **不要给强烈建议**
-- 让用户自行决定是否重跑
-
-### 📝 脚本生成原则
-
-- 优化规则脚本中尽量使用 `logger` 来打印日志，除一些整体步骤等信息可以使用 `print`
-- 示例：
-  ```python
-  # ✅ 规则内部分析日志用 logger
-  logger.debug(f"Stage {stage_id}: 分析倾斜情况...")
-  logger.info(f"发现问题: {description}")
-  
-  # ✅ 整体流程步骤可以用 print
-  print("步骤1: 解析输入文件")
-  ```

-# Original Prompt - 原始prompt
-
-```
-使用create-skill工具来创建skill，同时md尽量使用中文，文件名用英文，内容尽量用中文
-
-1. 输入了几个文件，对应的是job的plan和执行统计信息，plan是指包括执行计划、dag图等，执行统计信息是runtime跑的数据量和执行时间等；
-    如果job_profile.json为空，则相关处理job_profile.json逻辑可以略过；好比，增量状态表部分，有些逻辑主要是分析了plan.json，则应该可以给出这部分结果；
-2. 输入的文件分别是job_profile.json是执行器跑的时间和数据量统计；plan.json则是执行计划，包括dag图，两者需要结合起来，如hashjoin，从job_profile.json不知道是hash-hash shuffle hash join还是broadcast hash join等；
-3. 初始化一些主要信息，
-    3.1 分类sql。从plan.json找出cz.sql.text是不是 refresh命令，如果是，则按照分类sql来找出需要优化的点；
-    3.2 版本信息；plan.json可以获取版本(build_info里记录了，如，GitBranch:release-v1.2等信息），但版本不要暴露给结论，告诉你版本主要是后续会许升级到不同版本可能需要不同flag；
-    3.3 vc信息；同时可以查看cz.inner.is.ap.vc是不是ap，如果为0，则不是ap模式，表示是gp模式，如果为1，则为ap模式，后续优化也会区分是ap还是GP；对于ap，则拿cz.analyze.instance.executor.count参数表示vc等core数；如果是gp，则拿cz.sql.gp.vc.capability的参数，同时除以100得到数值表示vc的core数;
-    3.4 setting，plan.json记录了所有已经设置的flag，提示你如果已经有了，就不要再给建议了（不要在结论中提这些flag）
-    3.5 执行计划，plan.json中的dml->stages里记录了所有dag执行的stage信息，同时对应着job_profile.json那些stage；
-    3.6 统计所有operator耗时，以及在其stage的占比和整个sql占比，目的是为了后续做一些优化时，可以反复利用这些统计结果
-    3.7 根据上面初始化信息得到的场景来选择后续使用的分析和优化策略
-        增量计算job的分析和优化
-        compaction job分析
-        gpjob分析
-        apjob分析
-        等其他各种分类
-    3.8 整体每个阶段耗时分析；job_profile.json记录了每个阶段的开始时间，这样两个阶段之间就是这个阶段的耗时
-4. 增量计算refresh sql优化，即增量相关的sql优化
-  增量job任务优化分两大块，一种是从运行的stage/operator算子级别优化，一种是优化状态表
-  4.1 增量stage/operator级别优化
-    4.1.1 增量refresh还是全量refresh;可以从plan.json找到refresh的table名字，如果plan中refresh table的tablesink算子是OVERWRITE，但是不是写delta tablesink(plan.json中是找到tablesink算子，然后在table/path对应的字段找，可能是3元组，也可能是4元组，4元组，则一般最后一个是__delta__，表示写入delta文件的tablesink)，如果不是写delta tablesink则表示是全量(即overwrite sink的不是delta，且overwrite=true则表示是全量），否则是增量，同时忽略一些中间表，目前是通过名字带有__incr__这种pattern，表示的是中间状态，则这些暂时可以忽略，即不要找错了refresh的table名字；
-    4.1.2 单dop aggregate stage优化；如果stage是dop=1（可以从job_profile.json里找），如果stage里包含了Hashaggregate的Final/Complete状态（可以从相应plan.json找），并且是计算类似MULTI_RANGE_COLLECT,_DF_BF_COLLECT这些聚集函数，耗时较长，则可以给出走3阶段建议，需要设置set cz.optimizer.incremental.df.three.phase.agg.enable=true;即这个stage优化建议是设置该参数,如果已经配置了该参数，可能aggregete使用了one pass，即complete phase，则可以加上 set cz.optimizer.enable.one.pass.agg=false;来优化，同时如果还是耗时较长，没有生成3阶段，看下aggregate上的bits是多少，如果大于等于536870912，小于1073741824，则可以设置 set cz.optimizer.df.three.phase.agg.bf.width.threshold=某个值，即bits大小，因为默认该阙值是1073741824(1.3版本以及1.3以下版本是这个，1.3以上默认值是536870912)，小于这个则不会生成3阶段，如果bits小于536870912，建议不要修改该参数；如果有类似final stage还是很慢，麻烦看下它上游stage，是不是没有走aggregate的P2，这样也会导致final agg很慢，如果是同样给出再看看没有开启3阶段，以及bits是不是比1073741824小，则需要调整；请同时看是否开启3阶段以及bits大小是否符合，否则仅仅开启3阶段还是无法达到预期；额外条件，如耗时，耗时比较多
-        即优化条件：
-        aggregate是Final或Complete状态，且上游不是P2状态，即没有开始3阶段aggregate
-        （耗时超过20s以上且占总体10%以上）或者 耗时超过30s
-        stage输入数据（一般是shuffle read算子）超过20M
-        dop=1
-        agg有指定agg function
-        如果未打开，则可以加上3阶段优化flag set cz.optimizer.incremental.df.three.phase.agg.enable=true;,如果已经有cz.optimizer.df.enable.three.phase.agg=true，则也不需要单独设置打开3阶段flag功能；
-        但，如果不是3阶段需要检查bits是否满足，不满足需要额外加width threshold大小
-    
-        如果看到有aggregate是有MULTI_RANGE_COLLECT，但是没有_DF_BF_COLLECT或者_DF_SET_BF_COLLECT，则高优先级提示，说明bf(bloom filter)未收集对于裁剪会不佳；如果是1.3版本，则添加这些set cz.optimizer.incremental.df.three.phase.agg.enable=true;
-                set cz.optimizer.df.three.phase.agg.bf.width.threshold=536870912;
-                set cz.optimizer.df.bf.width.max=2147483648;
-                set cz.optimizer.df.bf.width.min=1073741824;
-                set cz.optimizer.incremental.enforce.creating.bf=true;
-        但如果已经存在flag，则不要加；
-    4.1.2 hash join优化；如果stage且耗时较长，如果stage里有join，且join占比比较多，可以看看是不是join的算法是hash-hash算法还是broadcast算法，统计信息可以从job_profile.json找，使用了什么算法，可以从plan.json找，一般来说，如果是broadcast，且shuffle量超大，则可以考虑禁止broadcast hash join，则给出优化建议是set cz.optimizer.enable.broadcast.hash.join=false;
-    4.1.3 stage包含tablesink算子优化；我们stage的dop是通过累加得到，如果stage包含了tablesink算子(且不是partial sink,判断逻辑是sink算子的flags字段, flags & 0x20!=0表示partial sink；同时也不是DELTA sink，即path最后一个元素是__delta__的4元组)，但是dop与上游不太一致，如果该stage耗时比较长，dop又与上游dop差异较大，且stage耗时较长(占总体超过10%)则可能是由于会根据table的目标文件大小自动调整了dop，则给出set cz.sql.enable.dag.auto.adaptive.split.size=false;（要求是已经设置该flag为true才需要），该参数目的是不根据table的目标文件大小来自动调整dop;如果在这种场景下，stage里没有tablesink算子不要加该参数，即dop小并不是由于需要根据table目标文件大小来调整；同时建议看看每个stage的taskCount，如果其上游dop和自己相差不大，建议不要设置cz.sql.enable.dag.auto.adaptive.split.size，即下游stage一般不会超过上游dop,在不超过情况下不需要设置；
-        即，优化条件
-        stage包含tablesink算子（且不是partial sink，判断逻辑：flags & 0x20 != 0；也不是DELTA sink，即path最后元素是__delta__）
-        stage耗时占总体10%以上
-        dop与上游差异大
-        dop如果与上游dop差不多（即计算依赖stage的
-        task count)，则不需要额外设置cz.sql.enable.dag.auto.adaptive.split.size=false，即不需要根据此情况调整dop
-        stage的dop大于上游stage的dop，则也不需要调整该参数，即下游dop都已经大于了上游，为啥还要调
-    4.1.4 最大dop优化提示；我们dag这边限制了map的最大dop=4096，reduce最大dop=2048，所以碰到类似这种dop可以认为不是dop有问题，除非你有足够信服的理由，或者主动调整过这些dop，如cz.optimizer.mapper.stage.max.dop,cz.optimizer.reducer.stage.max.dop这些对应的flag;
-    4.1.5 spillingBytes优化；关于spillingBytes分析，请按照算子级别来分析支持，一般有几种情况，一种是stage级别的总spill大小，还有一种是operator级别，可以相关spill stats看到有opId的，所以请根据这些级别来分析；如果是shuffle write的spill可能可以忽略；
-    4.1.6 倾斜优化提示；
-        1）profile里看stage的taskSummary每个task情况；如果发现只有少于5%的task有数据，则可能认为倾斜；同时需要满足stage耗时占总体超过15%才认为值得优化（避免对耗时很短的stage进行优化）；如果stage有scan算子，则看看尝试提示调整split size；set cz.mapper.file.split.size=xxx;默认是256M(268435456)，可以调小到64M等；如果有shuffleread，则可以提示关注是否有倾斜数据;
-    4.1.7 从job_profile.json中taskSummary拿到每个stage的dop(可以参考4.1.3对应的代码),分析每个task跑的时间，假设给足资源(即vc core数，见3.3)情况下，整体stage需要跑多久（如，最大task时间，以及总体task数在现有资源下跑多少轮可以结束），然后再对比实际跑了多久，如果实际跑的时间是预计资源足情况的2倍以上，则给出提示；
-    4.1.8 请你给出其他我未发现的问题，这里我发现你完全没理解，即不给任何分析，这里可以对所有stage看看时间耗时，对于那些比较慢的，可以主动分析为什么慢，如operator慢？还是其他等原因，希望你可以更smark点
-  4.2 状态表优化
-    4.2.0 如果给的prompt中没有提到使用状态优化，则不需要来使用下面优化原则来优化
-    重要：关于状态表这些优化必须是对应算子的对应增量算法，如aggregate则必须是增量算法产生的，join/window等都类似；可以根据4.2.1.2来判断；即只有包含增量hint的算子才需要进行状态表优化分析，没有增量hint的算子应该跳过；
-    4.2.1 看看当前的job是否是增量刷新的job，即4.1.1提到的如何判断是增量还是全量，以及增量计算的整体plan分析
-        4.2.1.1 识别所有operator(算子)是delta还是snapshot；如果是增量plan，由于是增量计算的plan，可以收集哪些表是是增量数据，哪些是读snapshot其中，对于tablescan算子，incrementalTableProperty有from/to分别记录了版本是从哪个版本到哪个版本，如果 from=28800，to=57000，则表示delta，如果from=-9223372036854775808，且to=28800表示表读数据的上个状态，或from=-9223372036854775808,to=57600，表示是当前状态，即(from=-9223372036854775808,to=28800，即上个状态或者说上个snapshot) + (from=28800, to=57600,即delta数据) = (-9223372036854775808=-9223372036854775808,to=57600，当前状态或者当前snapshot)
-        ，即 只有在from=28800且to=57600情况下表示tablescan的数据是delta,如
-        incrementalTableProperty": {
-            "from": "28800",
-            "to": "57600",
-            "fromMetaVersion": "0",
-            "toMetaVersion": "0"
-        }，该json例子表示是delta，其他都是snapshot，snapshot有一个明显特征是from=-9223372036854775808
-        注意：只有包含incrementalTableProperty的tablescan才需要分析，没有该属性的tablescan（如delta元数据扫描）应该跳过；
-        同时，需要区分业务数据扫描和元数据扫描：如果schema包含file_path, pos, commit_ts, operation, field_id, value等字段，则是delta元数据扫描，不是业务数据，应该跳过分析；
-        这样就方便分析增量算法，对于join/aggregate/window增量算法你自己根据相关知识找到算法逻辑，从而推导出增量plan的形态,如delta(join)算法=delta(Left) join delta(right)，即计算出left和right的delta数据就可以得到join的delta，也可以认为是重算rule，类似对于aggregate/window也是类似，下面的一些分析请区分出哪个是真正的join/aggregate/window的增量算子再添加状态，有些aggregate是算法的一部分，而不是对应原始sql里的aggregate，请注意区分，同时window/join也是类似
-        一般一元算子，如果输入是delta，则自己输出也是delta，输入是snapshot，则自己输出也是snapshot;
-        如果是join，只有left和right都是snapshot，join结果才是snapshot；
-        对于union多元算子，如果输入都是snapshot，则union输出也是snapshot，如果全部输入是delta，则union输出也是delta，如果部分delta，部分snapshot，应该也是snapshot，但这种plan一般不太会出现，也可以列出来，看看是不是你脚本处理问题；
-        其他多元算子，可以展示出来，可能遗漏了，一般也可以按照union规则处理；
-
-        ⚠️ 重要补充：增量算法Hint优先规则
-        - 如果算子有增量算法hint（如IncrementalJoinRule, IncrementalAggregateRule等），该算子应该被标记为delta
-        - 这是因为增量算法是用来处理增量数据的，即使输入是snapshot，增量算法也会输出delta
-        - 增量算法的语义：可以接受SNAPSHOT输入并产生DELTA输出（通过比较两个snapshot计算差异）
-        - 检查方法：在算子的JSON中查找"Incremental"或"DeltaState"关键字
-        - 优先级：增量hint检查应该在基于输入的传播规则之前执行
-        - 实际案例：HashJoin有IncrementalJoinWithoutCondenseRule hint，即使一个输入是SNAPSHOT，另一个是DELTA，该HashJoin仍应标记为DELTA
-
-        同时在plan.json里找到所有operator对应的Id，注意这里的ID不是代码中那些index下标，即使用 plan.json 中的实际 operator ID，而不是数组索引；注意这里一个算子可能有多个下游
-        注：这里依赖关系不要和stage挂勾，代码如果有请修正；
-        4.2.1.2 识别不同算子的增量算法；4.2.1.1已经知道了所有增量算子的依赖关系，你就能自动识别增量算法，可以把所有算子operator的delta/snapshot依赖关系整理串联起来；可以得到所有算子是计算delta还是snapshot，同时有些算子会有hint记录类似Rule:xxx这种pattern，如，Rule:IncrementalLinearFunctionAggregateRule，这个增量rule表示是计算aggregate的一种增量算法（即，rule名字包含了Aggregate，其他规则类似），如果这种hint不是在Aggregate(如，在join上)上，则说明这些算子是为了计算Aggregate增量算法的一部分；其他类似join/window增量算法也可以类似处理，有些hint计算的Rule有一些算子Id，如果一个Id出现在不同地方，说明这些整体都是来计算同一个算子的增量算法，如Rule:IncrementalJoinWithoutCondenseRule_cz::optimizer::LogicalJoin#31766417，这里的LogicalJoin#31766417表示为了计算该join算法而加的hint，这样所有相同都是为了计算同一个join，即属于Join算法的一部分；有些增量算法会打上其他hint，类似HINT=delta,DeltaState:[1,1896] - [1,6393]_IncrementalWindowSetDeltaRule#cz::optimizer::Window#293342，其中第一部分delta表示计算delta，即增量算法都是计算delta数据来优化，DeltaState表示该算子是整体增量算法的状态算子，IncrementalWindowSetDeltaRule表示是使用的算法，Window#293342则表示是对哪个算子计算了增量算法，如果没有这些类似Id，则可能是没有加上id来标识，不要误把没有加的hint当作是认为计算同一个算子；然后这样找出每次计算一个算子增量算法的边界其实可以区分出来；
-        如aggregate，如果是重算算法，则可能是根据([输入是delta] join [输入的snapshot])得到变动的aggregate输入，然后再计算aggregate就可以得到aggregate增量算法，所以这里aggregate增量算法就用到了join算子等；
-        4.2.1.3 算子增量算法对应的subplan，如包含哪些算子，算子对应的root阶段是什么；上面一步一步得到了每个算子的delta/snapshot，以及他们之间的依赖关系，这些都是可以认为是operator之间关系，忽略stage之间关系；通过上面hint以及operator之间的依赖关系，这样就可以知道这一些长串的算子对应了某个算子的增量算法，把这些进行归类，需要把一个增量算法对应的所有算子都找到，这里对应的plan.json的"id"字段表示每个算子的唯一id；
-        根据4.2.1.2找到相同增量算法的算子，对于一些没有找到id的rule hint应该往自己下游继续查找，找到第一个带有id且同类（是指是相同算子，如，都是agg/window/join等）的增量算法，这些算子联通(遍历)起来的算子一定属于该算法的subplan一部分（即，类似有N个点组成的一个图，点中间的所有算子肯定属于该增量算法），然后按照下面规则遍历“这些一定属于该算法的算子”的上下游算子来剩下的其他算子属于该增量算法，直到边界算子结束;
-        这里的算子增量算法对应的subplan不是让你把rule相同的合在一起，rule相同的算子肯定来源于同一个算子对应的增量算法，而是让你把某一个增量算法涉及到的所有算子都包含起来，这些算子不一定有Rule这些hint，即他们是一个执行的subplan，而不是这些零散的hint operator组成，即subplan 应该包含整个执行路径的所有算子，而不仅仅是有 Rule hint 的算子;
-
-        关于DeletePlan的处理：
-        - DeletePlan相关hint用于表示删数据的plan，不属于任何增量算法
-        - 在解析Rule hints时，应该忽略（过滤）所有DeletePlan相关hint，不作为增量算法的起点
-        - 在遍历查找subplan时，如果遇到DeletePlan相关算子，必须作为边界条件终止遍历
-        - 为什么必须终止而不是跳过：因为plan是执行路径，如果跳过DeletePlan继续查找，找到的subplan会缺少中间算子（不完整），这样的subplan不能算是增量算法的一部分
-
-        每个增量算法包含哪些operators，需要设置边界条件：
-        (1)碰到不是相同hint要终止，避免跨越算法边界，需要添加到subplan里；
-        (2)aggregate增量算法在查找自己涉及哪些算子时，上游碰到了final/complete状态也要终止，即表示在自己算delta，那已经结束了，需要添加到subplan里；
-        (3)碰到deleteplan相关算子必须终止，因为它不属于任何增量算法，且plan是执行路径不能跳过，不需要添加到subplan里；
-        (4)对于snapshot的算子，必须终止，因为snapshot表示snapshot状态，用来构造增量算法的输入节点，不需要把计算snapshot的整个过程都添加到增量算法的operators中，但snapshot算子本身属于增量算法一部分，需要添加到subplan里；
-        (5)如果是calc有hint，且hint包含了DeltaState和Incremental这些也需要终止，避免跨越算法边界；如，类似DeltaState:[1,14] - [1,43]_IncrementalJoinWithoutCondenseRule#cz::optimizer::LogicalJoin#973；注意：这种calc算子虽然要终止遍历，但在bottom-up遍历时应该将该算子包含到对应增量算法的算子中，即包含该算子但不继续向上游或下游遍历，需要添加到subplan里；
-        (6)增量算法查找算子时，如果碰到aggregate，且aggregate的聚集函数包括MULTI_RANGE_COLLECT或者_DF_BF_COLLECT，则终止，不需要添加到subplan里，因为这个是一个df的aggregate，仅仅是优化的一个plan，不需要添加；
-
-        验证规则（这些是规则不是告警，如果不满足，说明脚本有问题，请修改）：
-        - 同一个operator不应该属于两个不同的增量算法，或者只有增量算法的对应root节点或者tablescan才能横跨多个增量算法
-        - 如果一个算子又不是增量算法的root节点，又属于多个增量算法，则应该有问题
-        - 由于计算算子的delta/snapshot是从上游operator到下游operator经过propogate，所以如果某个operator属于了上游的增量算法，就不应该属于下游
-        - 从找到的root节点开始top-down遍历所有算子，在碰到了非边界算子前是不是有其他增量算法的算子，如果有，说明脚本有问题；同时保证自己的所有operator一定能遍历到，如果还有没遍历的算子，说明脚本有问题，请修改；
-            4.2.1.3.1 Aggregate算子的增量算法，如果发现有hint，则可能需要往依赖的下游算子继续查找，找到是Final/Complete状态的Aggregate算子才算结束，甚至有些Aggregate增量算法可能是由多路union得到，则这样还需要把union下游算子找到Aggregate的Final/Complete算子，即union 两边可能包含了相同的hint，则需要这些输入相交合并后继续查找得到他们的subplan，这些执行路径的算子也属于Aggregate；其他算子的增量算法应该也需要这样查找，即对于相同hint（表示同一个算子对应的增量算法，注意有些没有Id来唯一标识，这个时候别搞错了）如果不是同一个分支执行路径算子，需要合并起来得到；
-        每个增量算法得到了自己所有算子后，把所有tablescan算子找出来，如果所有的delta类型的scan全部是appendonly的tablescan，则显示出来，并标注；如果不全部是，也请显示每个tablescan是不是appendonly；appendonly信息在4.2.1.5里已经得到，从这里拿；
-        4.2.1.4 展示增量算法以及显示查看增量算法的状态信息/状态图等；把整体增量算法是计算哪些算子的依赖关系画出来，好比，这一堆算子是计算aggregate，这一堆算子是计算join等等，同时画出他们的依赖关系，这样就知道先计算aggregate再计算join，还是先计算join再计算aggregate等; 同时可以让prompt方式可以查看到增量算法图或者状态图，如哪些算子组成了aggregate算法，哪些算子组成了join等等(即脚本里应该可以直接分析查看，如传递参数等)；
-        4.2.1.5 算子delta是appendonly(纯增delta)还是有删除的delta;在4.2.1.1已经计算了算子是delta还是snapshot，现在需要区分delta是纯增还是有减（有删除的行），因为在纯增场景对于aggregate/window可以用一些更优的算法；
-        scan如果是delta，则看是不是输出__incremental_deleted列（注意是过去式deleted，不是delete）。检查方法：从算子的实际输出列（operator.schema.structTypeInfo.fields）查找是否输出该列，而不是从表定义的完整schema（tableSchema）查找。如果输出__incremental_deleted列，则表示delta不是纯增；如果没有输出，则表示delta是纯增；
-        join算子，则看所有的input是不是delta，如果只有一路是delta，且join type是inner/anti/left semi，则继承该输入的delta是不是纯增；如果所有输入input都是delta，所有delta都是纯增，且join上有类似HINT=Rule:这种pattern，且join type是inner/left_semi/anti时，则join的delta也是纯增，否则认为是非纯增；
-        aggregate/window算子继承输入的delta是否纯增。增量算法标记（4.2.1.2）只表示使用了增量算法，不影响append-only判断；append-only完全取决于输入数据（TableScan是否输出__incremental_deleted列）；
-        其他算子都是把所有输入的delta一起看，只要有一路不是纯增，则表示该算子delta都不是纯增的；
-        还有一些规则，如，window，类似这种HINT=delta,DeltaState-:[1,1896] - [1,6393]_IncrementalWindowSetDeltaRule#cz::optimizer::Window#44的pattern，DeltaState-中的-表示有删除，DeltaState+中的+表示是纯增，所有aggregate/join都有类似pattern；
-    4.2.2 提示非增量原因；如果job非增量刷新，且版本小于等于1.3，则请设置这些flag（
-        set cz.optimizer.print.non.incremental.reason=true;
-        set cz.optimizer.print.non.incremental.reason.msg.max.length=100000;
-        set cz.optimizer.incremental.force.incremental=true;
-        ），加上这些flag后，会提醒用户没有增量的原因；如果是1.4以及以上版本，则如果加上cz.optimizer.incremental.try.incremental.refresh.enabled=true,会提示为什么没有走增量；
-    下面优化策略都是基于plan是增量plan而需要查看的，所有算子之间的依赖关系理论上4.2.1已经构建好了，下面规则应该复用这些已经构建好的依赖关系；
-    同时关于状态表这些优化必须是对应算子的对应增量算法，如aggregate则必须是增量算法产生的，join/window等都类似；可以根据4.2.1.2来判断；
-    4.2.3 window算子在输入delta是appendonly(即纯增的增量，没有删除delta)优化；
-        window算子的父节点是calc，且存在 row number=1的pattern（表示的是window的rownumber函数输出后，在calc里面有这个列=1的pattern），请看看window的输入是否是append-only的delta（即，4.2.1.5）。注意：判断window输入是否append-only应该使用4.2.1.5中IncrementalAlgorithmAnalyzer分析的全局结果（operator_append_only_types），该结果包含了跨stage的所有算子的append-only信息，而不是在当前stage内搜索TableScan（因为TableScan可能在不同stage）。如果是append-only且rn=1的pattern，但是window没有使用IncrementalLinearTopKWindowRule增量算法（注意：支持V1和V2版本，即IncrementalLinearTopKWindowRule或IncrementalLinearTopKWindowRuleV2），则请设置以下flag继续尝试cz.optimizer.incremental.window.sd.to.sd.rule.enable=false; 如果是append-only的delta输入，则一直检查到tablescan，查看tablescan的table属性是否有property：incr.append.only.table=true 或者 job是否flag具备 cz.optimizer.incremental.append.only.tables='xxx'，如果没有这些flag或者properties请提醒用户需要在该表添加上incr.append.only.table=true属性（注意：incr.append.only.table属性仅用于提醒用户设置，不影响append-only的判断逻辑）；
-        rn=1 pattern如何查找可以类似参考{"function":{"from":"","name":"EQ","builtIn":true,"arguments":[{"reference":{"id":"0","local":false,"from":"","name":"","refType":"LOGICAL_FIELD"},"typeReference":1},{"constant":{"bigint":"1"},"typeReference":1}],"properties":{"properties":[]},"execDesc":"EQ(i64,i64)->b","functionProperties":{"properties":[]}},"pt":{"start":{"line":1,"col":7356,"pos":7355},"end":{"line":1,"col":7364,"pos":7363}},"typeReference":13}
-        这里的EQ表示等于(=)，constant有个值bigint:1，表示是1，所以对应的其实就是xx=1
-    4.2.4 基于我教给你的4.2.3的方法，看看当前query中是否还包含append-only的scan，如果包含，根据你的经验预判一下当前是否使用的算法并非最优的
-        核心思想：如果系统中仍然存在对append-only数据的扫描，说明可能没有充分利用append-only特性进行优化。理想情况下，append-only数据应该通过增量算法处理，而不是重复扫描。
-        检查逻辑：
-        1. 根据4.2.1.1规则，只分析有incrementalTableProperty且from != -9223372036854775808的delta业务数据扫描
-        2. 排除delta元数据扫描（schema包含file_path, pos, commit_ts, operation, field_id, value等字段）
-        3. 排除中间状态表（表名包含__incr__, __state__, __temp__等pattern）
-        4. 对于真正的append-only业务数据扫描，分析为什么还在扫描而不是使用增量算法：
-           - 检查是否可以使用状态表避免重复扫描
-           - 检查是否已使用增量算法（通过hint检测）
-           - 综合评估append-only数据特性是否被充分利用
-    4.2.5 是否有创建中间状态表；即看整个job的所有stage中tablesink是不是有表名包含__incr__；如果不包含，可以设置cz.optimizer.incremental.enable.state.table=true;来开启中间状态优化。但是在开启之前，我希望你根据经验判断一下当前是否值得存储中间状态，你可以从以下几个方面进行判断：1.是否需要状态（可以参考流计算的带状态计算的定义），但必须是增量算法产生的算子（根据4.2.1.2的hint判断），2.状态表是否过大（请根据当前看到的每一步的stats信息和输入表的增量数据大小进行合理判断）；
-        对于有有状态算子，需要区分增量算法是不是对应的增量算法，如，join算子对应的rule是join，aggregate类似，除非是第一次出现hint的operator，否则应该都有对应关系，不要错误把一些增量算法的中间算子当作自己本身
-        注意：状态表检查应该是job级别的，不仅仅检查当前stage，需要检查整个job的所有stage是否已包含中间状态表，避免误判；
-        基于算子是增量算法来创建中间状态表优化的逻辑，在未提示情况下默认不开启；
-        找算子是snapshot（即类似全量计算这个subplan）占比比较高的(如，15%以上等)，一般这种需要创建中间表状态表；这里的operator是snapshot是指整个路径上所有的snapshot的耗时在整体的占比，因为如果中间表物化后就可以减少这部分计算；同时打印出该snapshot的“骨架”，即把重要算子打印出来，如aggregate/join/window/tablescan，aggregate打印出聚集函数，window类似，这样方便从原始sql找到对应的sql，这样join等就知道是从哪个tablescan开始到哪里结束需要创建中间表；
-    4.2.6 aggregate linear rule优化；该aggregate必须设置上了hint包含类似4.2.1.2的一些状态hint，如果不包含，说明该aggregate算子不是原始sql中的aggregate，而是其他优化器rule等自己生成的，这些不需要检查；然后看看当前任务中aggregate的计算是否利用上了之前的计算结果（对于SUM，COUNT希望无论如何都尽量使用之前的结果，对于MIN，MAX希望在append-only的情况下尽量使用之前的结果），如果发现没用上，请根据4.2.5我教会你的方法看看是否存在状态，如果状态存在，请根据4.2.1.5教会你的方法看看是否有append-only的输入，如果是append-only但是缺少系统hint的，请补充上hint
-    4.2.7 占比时间长calc可以存状态，如，calc占整体stage超过30%，同时整个stage在整体耗时占比15%以上,如果发现这类calc，可以看calc是不是有比较占比高的function计算，特别是udf(即用户自定义function)则可以通过set cz.optimizer.incremental.create.rule.based.table.on.heavy.calc=true;进行优化
-        额外条件：
-        - calc必须是snapshot状态（不是delta），如何获取见4.2.1.1规则，从operator_data_types中获取
-        - 输出信息应包含：calc耗时、calc占stage比例、stage耗时、stage占整体比例，类似4.1.6倾斜规则的详细输出
-    总体所有满足这些优化pattern的，请可以显示出来，提供查看
-
-5. compaction优化，TODO
-6. gp job任务优化，TODO
-7. ap job任务优化，TODO
-8. job报错分析
-    8.0 统一从job_profile.json的message里收集所有错误信息，可能会有重复报错信息，记得精炼错误信息，以便提供下面错误分析优化以及给出建议；且job_profile.json中有"hint"记录了设置过哪些flag，如果下面建议提示设置什么flag，请检查是否存在，如果不存在才提示加flag；
-    8.1 提交冲突报错；从job_profile.json中找message里有如“this job has conflicts with another concurrent job which updates”，解决方法提示只要重跑整个job；
-    8.2 优化器报错；
-        8.2.1 提示生成playback信息；message里如果包含类似“Optimizer internal error”这种错误，则提示设置cz.sql.playback.scratch=true，重新跑报错job，这样会有playback信息，提供优化器定位问题；
-        如果已经设置了cz.sql.playback.scratch=true，则不需要提示添加flag，而是提示已经有了信息可以找技术支持；
-        8.2.2 TODO（针对不同错误信息可能有不同策略，暂时未实现）
-9. 不要给没有提示的参数，即有些你给的flag是凭空说的;只在发现实际问题时才建议参数；其他的请单独列出，但是不要给什么强烈建议这种重跑，交给用户自己决定；
-10. 可以将脚本按照不同sql分类来进行拆开，后续便于管理，即要考虑后续skill如何迭代；构建脚本尽量以不同场景来构建，方便扩展，如增量是一类，compaciton是一类等等;
-   脚本命名不要和数字结合，容易导致prompt变了，但脚本数字和prompt对应不上问题
-11. 脚本和md里不要出现v3，规则3这种带有版本或者数字第几章的东西，后续无法维护
-12. 脚本生成原则，优化规则里尽量用logger来打印，除一些整体的步骤等打印可以使用print

-# Job Performance Analyzer Skill - 模块化架构设计
-
-## 当前问题
-- 单一脚本 30KB+，所有逻辑混在一起
-- REFRESH SQL、Regular SQL、AP/GP 模式代码耦合
-- 后续新增规则（如 4.2 状态表优化）难以扩展
-- 规则迭代时需要修改大量代码
-
-## 新架构设计
-
-### 关键理解
-1. **第 3 章是完整的增量计算分析**，包含两个部分：
-   - 3.0-3.6: Stage/Operator 级别优化（对应原来的 4.1）
-   - （未来）状态表级别优化（对应原来的 4.2）
-2. **第 4 章是 AP 模式**（独立的）
-3. **规则命名不带数字**，避免后续调整困难

-
-## 核心设计原则
-
-### 1. 单一职责
-每个规则文件只负责一个检测规则：
-```python
-# rules/incremental/stage_optimization/single_dop_aggregate.py
-class SingleDopAggregate:
-    """3.1: 单 DOP 聚合优化"""
-    
-    name = "single_dop_aggregate"
-    category = "incremental/stage_optimization"
-    
-    def check(self, stage_data, context):
-        """检查是否触发该规则
-        
-        触发条件：
-        1. Stage DOP = 1
-        2. 包含 HashAggregate P1
-        3. 使用高成本聚合函数
-        4. (耗时 > 20秒 且 占比 > 10%) 或者 耗时 > 30秒
-        5. stage 输入数据（shuffle read）> 20MB
-        """
-        pass
-    
-    def analyze(self, stage_data, context):
-        """分析问题并返回建议
-        
-        分析步骤：
-        1. 检查三阶段聚合参数
-        2. 检查是否退化为 one-pass
-        3. 检查 Bloom Filter bits
-        """
-        pass
-    
-    def get_recommendations(self, analysis_result):
-        """生成参数建议"""
-        return [
-            {
-                'setting': 'cz.optimizer.incremental.df.three.phase.agg.enable',
-                'value': 'true',
-                'priority': 1,
-                'reason': '...'
-            }
-        ]
-```
-
-### 2. 分析器组合规则
-每个分析器组合对应类型的规则：
-```python
-# analyzers/incremental_analyzer.py
-class IncrementalAnalyzer(BaseAnalyzer):
-    """增量计算分析器 (第3章 REFRESH SQL)"""
-    
-    def __init__(self):
-        # Stage/Operator 优化规则 (3.0-3.6)
-        from rules.incremental.stage_optimization import (
-            RefreshTypeDetection,
-            SingleDopAggregate,
-            HashJoinOptimization,
-            TableSinkDop,
-            MaxDopCheck,
-            SpillingAnalysis,
-            ActiveProblemFinding
-        )
-        
-        self.stage_rules = [
-            RefreshTypeDetection(),    # 3.0 增量/全量判断
-            SingleDopAggregate(),      # 3.1 单 DOP 聚合
-            HashJoinOptimization(),    # 3.2 Hash Join
-            TableSinkDop(),            # 3.3 TableSink DOP
-            MaxDopCheck(),             # 3.4 最大 DOP
-            SpillingAnalysis(),        # 3.5 Spilling
-            ActiveProblemFinding(),    # 3.6 主动问题发现
-        ]
-        
-        # 状态表优化规则（未来扩展）
-        self.state_table_rules = []
-    
-    def analyze(self, aligned_data):
-        # 先执行 Stage 优化分析
-        for rule in self.stage_rules:
-            if rule.check(aligned_data, self.context):
-                result = rule.analyze(aligned_data, self.context)
-                self.add_finding(result)
-        
-        # 如果需要，执行状态表分析
-        if self.state_table_rules:
-            for rule in self.state_table_rules:
-                if rule.check(aligned_data, self.context):
-                    result = rule.analyze(aligned_data, self.context)
-                    self.add_finding(result)
-```
-
-### 3. 主脚本轻量化
-```python
-# scripts/analyze_job.py (主入口)
-from core.parser import PlanProfileParser
-from core.aligner import StageAligner
-from core.reporter import Reporter
-from analyzers import get_analyzer
-
-def main():
-    # 1. 解析输入
-    parser = PlanProfileParser(plan_file, profile_file)
-    data = parser.parse()
-    
-    # 2. 对齐 Stage/Operator
-    aligner = StageAligner(data)
-    aligned = aligner.align()
-    
-    # 3. 选择分析器
-    analyzer = get_analyzer(data.sql_type, data.vc_mode)
-    
-    # 4. 执行分析
-    findings = analyzer.analyze(aligned)
-    
-    # 5. 生成报告
-    reporter = Reporter(findings)
-    reporter.generate()
-```
-
-## 优势
-
-### 1. 易于维护
-- 每个规则独立，修改互不影响
-- 新增规则只需添加新文件，无需改动现有代码
-
-### 2. 易于测试
-```python
-# 可以单独测试每个规则
-def test_single_dop_agg():
-    from rules.incremental.stage_optimization import SingleDopAggregate
-    
-    rule = SingleDopAggregate()
-    stage_data = load_test_data("single_dop_case.json")
-    
-    # 测试触发条件
-    assert rule.check(stage_data, context) == True
-    
-    # 测试分析逻辑
-    result = rule.analyze(stage_data, context)
-    assert '三阶段聚合' in result['recommendations'][0]['reason']
-```
-
-### 3. 易于扩展
-- **新增 Stage 优化规则**: 在 `rules/incremental/stage_optimization/` 添加新文件
-- **新增状态表规则**: 在 `rules/incremental/state_table/` 添加新文件
-- **新增 AP 模式**: 创建 `analyzers/ap_analyzer.py` + `rules/ap_mode/`
-- **新增通用规则**: 在 `rules/common/` 添加
-
-**⚠️ 状态表优化规则的特殊性**：
-- 状态表优化规则**默认禁用**，需要通过 `enable_state_table_rules` 参数明确启用
-- 原因：根据 prompt 4.2.0 要求，如果用户没有提到使用状态表优化，则不需要执行这些规则
-- 使用方式：
-  ```bash
-  # 禁用状态表分析（默认）
-  cz-analyze-job plan.json job_profile.json
-
-  # 启用状态表分析
-  cz-analyze-job plan.json job_profile.json --enable-state-table
-  ```
-
-示例 - 添加新的 Stage 优化规则：
-```python
-# rules/incremental/stage_optimization/shuffle_optimization.py
-class ShuffleOptimization:
-    """新规则：Shuffle 优化"""
-    
-    name = "shuffle_optimization"

-# Stage/Operator 级别优化指南
-
-本文档包含增量计算 REFRESH SQL 的 Stage/Operator 级别优化规则。
-
-这是增量优化的第一部分，主要从运行的 stage/operator 算子级别进行优化。
-
-**相关文档**：
-- [增量算法分析](./incremental-algorithm-analysis.md) - 增量算法识别和分析
-- [状态表优化](./state-table-optimization.md) - 状态表相关优化规则
-- [优化原则](./optimization-principles.md) - 参数推荐原则

-## Stage/Operator 级别优化
-
-### 4.1.1 增量 refresh vs 全量 refresh
-
-**目的**：判断 REFRESH 是增量还是全量
-
-**判断方法**：
-1. 从 `plan.json` 找到 REFRESH 的目标表
-2. 定位对应的 TableSink 算子，获取 `table.path`
-3. 判断规则（基于 `path` 和 `overwrite`）：
-   - **如果** `path` 是 4 元组且最后一个元素是 `__delta__` → **增量 REFRESH**（写入 delta 文件）
-   - **如果** `path` 是 3 元组且 `overwrite=false` → **增量 REFRESH**
-   - **其他情况**（3 元组且 `overwrite=true`）→ **全量 REFRESH**
-
-**path 格式说明**：
-- **3元组**：`[workspace, namespace, table_name]` - 例如 `['gic_prod', 'kscdm', 'dim_ks_live_daily']`
-- **4元组**：`[workspace, namespace, table_name, '__delta__']` - 例如 `['gic_prod', 'kscdm', 'dim_ks_live_daily', '__delta__']`
-
-**注意**：忽略中间表（table_name 包含 `__incr__`、`__state__`、`__temp__` 等 pattern），这些是中间状态表。
-
-**代码示例**：
-```python
-# 从 TableSink 中获取 path 和 overwrite 标志
-table_sink = stage['operators'][i]['tableSink']
-path = table_sink['table']['path']  # 列表格式
-overwrite = table_sink.get('overwrite', True)
-
-# 判断逻辑
-if len(path) == 4 and path[-1] == '__delta__':
-    refresh_type = "增量"  # 写入 delta 文件
-elif len(path) == 3 and not overwrite:
-    refresh_type = "增量"  # overwrite=false
-else:
-    refresh_type = "全量"  # 3元组且 overwrite=true
-
-# 提取表名（在 path[2]）
-table_name = path[2]
-```
-
----
-
-### 4.1.2 单 DOP Aggregate Stage 优化
-
-**触发条件**（必须**全部**满足）：
-1. Stage 的 `dop = 1`
-2. Stage 耗时满足以下**任一**条件：
-   - **(耗时 > 20秒 且 占总耗时 > 10%)** 或者
-   - **耗时 > 30秒**
-3. Stage 输入数据（一般是 shuffle read 算子）**> 20MB**
-4. Stage 包含 **HashAggregate** 算子
-5. 聚合函数包含昂贵函数：`MULTI_RANGE_COLLECT`, `_DF_BF_COLLECT`, `BF_COLLECT`, `DF_BF_COLLECT`
-6. **聚合状态是 Final 或 Complete**（表示最后一个聚合阶段）
-7. **上游 stage 没有 P2 状态**（说明当前只有 2 阶段聚合，没有开启 3 阶段）
-
-**判断逻辑**：
-- 如果当前 stage 的 aggregate 是 **Final** 或 **Complete** 状态
-- 且上游 stage **没有 P2/PARTIAL2** 状态
-- 说明当前只有 **2 阶段聚合**（P1 → Final），需要优化为 **3 阶段**（P1 → P2 → Final）
-
-**优化建议**：
-
-1. **开启三阶段聚合**（如果未开启）：
-   ```sql
-   set cz.optimizer.incremental.df.three.phase.agg.enable = true;
-   ```
-   注意：如果已有 `cz.optimizer.df.enable.three.phase.agg=true`，则不需要重复设置
-
-2. **禁用 one-pass 聚合**（如果聚合退化为 Complete）：
-   ```sql
-   set cz.optimizer.enable.one.pass.agg = false;
-   ```
-
-3. **调整 BF bits 阈值**（如果 bits 在 512M-1G 范围内）：
-   ```sql
-   set cz.optimizer.df.three.phase.agg.bf.width.threshold = <bits值>;
-   ```
-   - 如果 `bits >= 536870912` 且 `bits < 1073741824`，需要设置此参数
-   - 默认阈值是 1073741824（1.3版本及以下），1.3以上版本默认值是 536870912
-   - 小于默认阈值不会生成 3 阶段
-   - 如果 `bits < 536870912`，不建议修改此参数
-
-**代码示例**：
-```python
-# 检查输入数据量（从 metrics 中获取）
-metrics = stage_data.get('metrics', {})
-input_bytes = metrics.get('input_bytes', 0)
-input_mb = input_bytes / (1024 * 1024)
-
-if input_mb < 20:
-    # 输入数据量太小，不需要优化
-    pass
-
-# 检查当前 stage 的聚合状态
-has_final = 'FINAL' in aggregate_mode
-has_complete = 'Complete' in aggregate_mode
-
-# 检查上游 stage 是否有 P2
-upstream_has_p2 = False
-for upstream_stage in upstream_stages:
-    if 'P2' in upstream_aggregate_mode or 'PARTIAL2' in upstream_aggregate_mode:
-        upstream_has_p2 = True
-        break
-
-# 判断是否需要优化
-if (has_final or has_complete) and not upstream_has_p2:
-    # 当前只有 2 阶段，需要开启 3 阶段优化
-    recommend_three_phase_agg = True
-```

-
-### 4.1.2.1 Bloom Filter 收集检测（高优先级）
-
-**目的**：检测增量计算中是否缺少 Bloom Filter 收集，这会导致数据裁剪效果不佳
-
-**触发条件**：
-1. Stage 包含 **HashAggregate** 算子
-2. 聚合函数包含 `MULTI_RANGE_COLLECT`
-3. **但缺少** `_DF_BF_COLLECT` 或 `_DF_SET_BF_COLLECT` 函数
-
-**判断逻辑**：
-```python
-# 获取所有聚合函数
-agg_functions = []
-for op in operators:
-    if 'hashAgg' in op:
-        agg_calls = op['hashAgg']['aggregate']['aggregateCalls']
-        for call in agg_calls:
-            func_name = call['function']['function']['name']
-            agg_functions.append(func_name)
-
-# 检查是否有 MULTI_RANGE_COLLECT
-has_multi_range = any('MULTI_RANGE_COLLECT' in func for func in agg_functions)
-
-# 检查是否缺少 BF 收集
-has_bf_collect = any(
-    '_DF_BF_COLLECT' in func or '_DF_SET_BF_COLLECT' in func 
-    for func in agg_functions
-)
-
-# 如果有 MULTI_RANGE_COLLECT 但没有 BF 收集，则需要优化
-needs_optimization = has_multi_range and not has_bf_collect
-```
-
-**优化建议**：
-
-**对于 v1.3 版本**，添加以下完整配置：
-```sql
-set cz.optimizer.incremental.df.three.phase.agg.enable = true;
-set cz.optimizer.df.three.phase.agg.bf.width.threshold = 536870912;
-set cz.optimizer.df.bf.width.max = 2147483648;
-set cz.optimizer.df.bf.width.min = 1073741824;
-set cz.optimizer.incremental.enforce.creating.bf = true;
-```
-
-**对于其他版本**，至少添加：
-```sql
-set cz.optimizer.incremental.enforce.creating.bf = true;
-```
-
-**注意**：
-- 如果参数已经存在且值正确，则不要重复推荐
-- 这是**高优先级**优化，因为缺少 BF 会严重影响增量计算的裁剪效果
-- Bloom Filter 用于在增量计算中快速过滤不需要的数据，提升性能
-
-**代码示例**：
-```python
-# 检查版本
-version_info = context.get('version_info', {})
-git_branch = version_info.get('git_branch', '')
-is_v13 = 'release-v1.3' in git_branch
-
-# 生成推荐
-if is_v13:
-    # v1.3 版本需要完整配置
-    params = [
-        ('cz.optimizer.incremental.df.three.phase.agg.enable', 'true'),
-        ('cz.optimizer.df.three.phase.agg.bf.width.threshold', '536870912'),
-        ('cz.optimizer.df.bf.width.max', '2147483648'),
-        ('cz.optimizer.df.bf.width.min', '1073741824'),
-        ('cz.optimizer.incremental.enforce.creating.bf', 'true')
-    ]
-else:
-    # 其他版本只需要强制创建 BF
-    params = [
-        ('cz.optimizer.incremental.enforce.creating.bf', 'true')
-    ]
-
-# 检查并推荐未设置的参数
-for param, value in params:
-    if settings.get(param) != value:
-        recommend(param, value, priority='HIGH')
-```
-

-
-### 4.1.3 Hash Join 优化
-
-**触发条件**：
-1. Stage 耗时 **> 10秒** 或 占总耗时 **> 8%**
-2. Stage 包含 Join operator
-3. Join 耗时 **> 30%** 的 Stage 时间
-
-**分析方法**：
-- Join 算法：从 `plan.json` 获取
-- 数据量/Shuffle 量：从 `job_profile.json` 获取
-
-**优化建议**：
-
-**IF** Join 算法 = `Broadcast Hash Join`  
-**AND** Broadcast/Shuffle 数据量异常大：
-
-搜索 settings 中 `cz.optimizer.enable.broadcast.hash.join`：
-
-**IF** 参数不存在 **OR** 值 = `true`：
-```sql
--- 推荐
-set cz.optimizer.enable.broadcast.hash.join = false;
-```
-
-**代码示例**：
-```python
-plan_str = json.dumps(stage['operators'])
-is_broadcast = 'BroadcastHashJoin' in plan_str or 'Broadcast' in plan_str
-```
-
----
-
-### 4.1.4 包含 TableSink 的 Stage DOP 优化
-
-**触发条件**（必须**全部**满足）：
-1. Stage 包含 **TableSink** 算子（排除 partial sink 和 DELTA sink）
-   - **Partial sink**: `flags & 0x20 != 0`
-   - **DELTA sink**: `path` 最后一个元素是 `__delta__`（4元组）
-2. Stage 耗时占总体 **> 10%**
-3. Stage DOP **与上游 DOP 差异较大**
-
-**不应推荐的情况**：
-- Stage **不包含** TableSink 算子
-- Stage DOP 与上游 DOP 接近（≥ 上游max * 0.5）
-- Stage DOP **已大于**上游 DOP（下游 DOP 都已经大于上游，无需调整）
-
-**原因推断**：
-系统可能根据**目标表文件大小**自动调整了 DOP。
-
-**优化建议**：
-
-计算上游最大 DOP：
-```python
-upstream_dops = [metrics['dop'] for sid, metrics in stages if sid != current_stage]
-max_upstream = max(upstream_dops)
-```
-
-**检查 TableSink 是否为 partial sink 或 DELTA sink**：
-```python
-# 从 plan.json 中的 TableSink 算子获取信息
-table_sink = operator.get('tableSink', {})
-flags = table_sink.get('flags', 0)
-table = table_sink.get('table', {})
-path = table.get('path', [])
-
-# 判断是否为 partial sink
-is_partial_sink = (flags & 0x20) != 0
-
-# 判断是否为 DELTA sink (path 最后一个元素是 __delta__)
-is_delta_sink = len(path) == 4 and path[-1] == '__delta__'
-
-# 只对非 partial sink 且非 DELTA sink 的 TableSink 进行 DOP 优化检查
-if is_partial_sink or is_delta_sink:
-    # 跳过
-    pass
-```
-
-**IF** `current_dop < max_upstream * 0.5` **AND** `current_dop <= max_upstream`：
-
-搜索 settings 中 `cz.sql.enable.dag.auto.adaptive.split.size`：
-
-**IF** 参数值 = `true`（已经设置该 flag 为 true 才需要）：
-```sql
--- 推荐
-set cz.sql.enable.dag.auto.adaptive.split.size = false;
-```
-
-**注意**：
-- 该参数目的是不根据 table 的目标文件大小来自动调整 DOP
-- 如果在这种场景下，stage 里没有 tablesink 算子不要加该参数
-- 如果上游 DOP 和自己相差不大（即计算依赖 stage 的 task count），则不需要额外设置
-- 如果 stage 的 DOP 大于上游 stage 的 DOP，则也不需要调整该参数
-
-⚠️ **警告**：此参数影响全局，请谨慎使用。
-
----
-
-### 4.1.5 最大 DOP 提示
-
-**DAG 限制**：
-- Map 最大 DOP = `4096`
-- Reduce 最大 DOP = `2048`
-
-**原则**：
-- 达到这些限制通常**不是问题**
-- **除非**用户显式调整过这些参数：
-  - `cz.optimizer.mapper.stage.max.dop`
-  - `cz.optimizer.reducer.stage.max.dop`
-
-**处理方式**：
-```python
-if stage_dop >= 4096 or stage_dop >= 2048:
-    # 检查是否用户主动设置了 max dop 参数
-    if 'cz.optimizer.mapper.stage.max.dop' in settings or \
-       'cz.optimizer.reducer.stage.max.dop' in settings:
-        # 可能需要分析
-        pass
-    else:
-        # 达到系统限制，这是正常的
-        print(f"Stage {stage_id} DOP达到系统限制，这是正常的")
-```
-
----
-
-### 4.1.6 数据倾斜检测
-
-**目的**：检测数据倾斜问题并提供优化建议
-
-**触发条件**：
-- 少于 **5%** 的 task 有数据（即 active task 比例 < 5%）
-
-**判断方法**：
-1. 从 `job_profile.json` 的 `taskSummary` 获取每个 task 的情况
-2. 统计有数据的 task 数量（`inputBytes > 0` 或 `outputBytes > 0`）
-3. 计算 active task 比例 = active_tasks / total_tasks
-
-**优化建议**：
-
-**场景 1：Stage 包含 Scan 算子**
-
-调整 split size 以缓解倾斜：
-```sql
-set cz.mapper.file.split.size = 67108864;  -- 从默认 256M (268435456) 调整为 64M
-```
-
-**场景 2：Stage 包含 Shuffle Read**
-
-提示关注上游是否存在倾斜数据，需要检查：
-- 上游 Stage 的数据分布
-- Shuffle 分区策略
-- 是否需要调整分区键
-
-**代码示例**：
-```python
-# 检查倾斜
-task_summary = profile.get('taskSummary', {})
-total_tasks = len(task_summary)
-active_tasks = 0
-
-for task_id, task_data in task_summary.items():
-    input_bytes = task_data.get('inputBytes', 0)
-    output_bytes = task_data.get('outputBytes', 0)
-    if input_bytes > 0 or output_bytes > 0:
-        active_tasks += 1
-
-active_ratio = active_tasks / total_tasks
-is_skewed = active_ratio < 0.05  # 少于 5% 的 task 有数据
-
-if is_skewed:
-    # 检查是否有 scan 算子
-    has_scan = any('Scan' in op.get('type', '') for op in operators)
-
-    if has_scan:
-        # 建议调整 split size
-        current_split_size = settings.get('cz.mapper.file.split.size', 268435456)
-        if current_split_size >= 268435456:
-            recommend_split_size = 67108864  # 64M
-
-    # 检查是否有 shuffle read
-    has_shuffle_read = any('ShuffleRead' in op.get('type', '') for op in operators)
-
-    if has_shuffle_read:
-        # 提示关注上游倾斜
-        print("检测到 Shuffle Read，请关注上游是否存在倾斜数据")
-```
-
----
-
-### 4.1.7 SpillingBytes 分析
-
-**分析级别**：
-1. **Stage 级别** - 总 Spill 大小
-2. **Operator 级别** - 可以看到 `opId` 的 spill stats
-
-**数据提取**：
-```python
-# Stage 级别
-spill_bytes = stage_data['inputOutputStats']['spillingBytes']
-
-# Operator 级别
-for op_id, op_data in stage_data['operatorSummary'].items():
-    if 'spillStats' in op_data:
-        op_spill = op_data['spillStats']
-        # 分析具体算子的 spilling
-```
-
-**注意**：
-- **Shuffle Write 的 Spill 可能可以忽略**
-- 重点关注其他算子的 Spilling
-
-**分析输出**：
-```python
-if spill_bytes > 1024**3:  # > 1GB
-    print(f"Stage {stage_id} Spilling: {spill_bytes/(1024**3):.2f} GB")
-    # 分析哪个 operator 导致
-    for op_id, op_data in operators:
-        if has_spill(op_data):
-            print(f"  Operator {op_id}: {op_spill} bytes")
-```
-
----
-
-### 4.1.8 资源效率分析
-
-**目的**：对比每个 Stage 的实际运行时间与理论资源充足情况下的预期时间，检测资源不足导致的性能问题
-
-**触发条件**：
-1. 有 profile 数据且 taskSummary 存在
-2. VC core 数有效（> 0）
-3. Stage 耗时 > 5秒
-
-**并发 Stage 资源竞争处理**：
-多个 stage 可能并发执行，共享 vc_cores 资源。分析时需要：
-1. 通过 `startTime`/`endTime` 找出与当前 stage 时间重叠的其他 stage
-2. 累加并发 stage 的 dop 作为被占用的资源
-3. 可用资源 = `max(1, vc_cores - 并发 stage 总 dop)`
-4. 用调整后的可用资源计算预期耗时
-
-**分析方法**：
-1. 从 `taskSummary` 获取每个 task 的运行时间（`endTime - startTime`）
-2. 找出最大 task 时间（`max_task_time`）
-3. 计算总 task 数
-4. 计算可用资源（扣除并发 stage 占用）
-5. 计算需要跑多少轮：`rounds = ceil(total_tasks / available_cores)`
-6. 预期耗时 = `max_task_time × rounds`
-7. 对比实际耗时与预期耗时，如果实际 > 2倍预期，则告警
-
-**VC Core 数获取**（参考 2.3）：
-```python
-# AP 模式
-vc_cores = int(settings['cz.analyze.instance.executor.count'])
-# GP 模式
-vc_cores = int(settings['cz.sql.gp.vc.capability']) // 100
-```
-
-**代码示例**：
-```python
-# 计算并发 stage 占用的资源
-concurrent_dop = 0
-for other_stage in all_stages:
-    if other_stage.id == current_stage.id:
-        continue
-    if other_stage.startTime < current_stage.endTime and other_stage.endTime > current_stage.startTime:
-        concurrent_dop += other_stage.dop
-
-available_cores = max(1, vc_cores - concurrent_dop)
-
-# 从 taskSummary 获取每个 task 的运行时间
-task_times = []
-for task_id, task_data in task_summary.items():
-    start_time = int(task_data.get('startTime', 0))
-    end_time = int(task_data.get('endTime', 0))
-    if end_time > start_time:
-        task_times.append(end_time - start_time)
-
-max_task_time = max(task_times)
-total_tasks = len(task_times)
-
-# 计算理论最优耗时（使用扣除并发后的可用资源）
-rounds = (total_tasks + available_cores - 1) // available_cores
-estimated_time = max_task_time * rounds
-
-# 对比
-efficiency_ratio = actual_elapsed / estimated_time
-if efficiency_ratio >= 2.0:
-    # 资源效率偏低，可能存在资源排队或调度开销
-    report_issue(stage_id, actual_elapsed, estimated_time, efficiency_ratio)
-```
-
----
-
-### 4.1.9 主动问题发现（**必须执行**）
-
-**要求**：
-- **不允许**"没有发现问题"的结论
-- 必须遍历**所有 Stage**
-- 对耗时较长的 Stage 主动分析原因
-
-**分析步骤**：
-
-1. **找出 Top 耗时 Stage**（至少 Top 5）
-
-2. **对每个 Stage 分析**：
-   ```python
-   # a. 找瓶颈 Operator
-   bottleneck_op = max(operators, key=lambda op: op['max_time_ms'])
-   
-   # b. 判断原因
-   if bottleneck_op['skew_ratio'] > 5.0:
-       reason = "数据倾斜严重"
-       suggestion = "SQL 改写或数据预处理"
-   
-   elif bottleneck_op['stage_pct'] > 80:
-       reason = "单个 Operator 占主导"
-       suggestion = "检查算子逻辑或数据分布"
-   
-   elif stage_dop <= 10:
-       reason = "DOP 较低"
-       suggestion = "检查是否需要提高并行度"
-   
-   elif stage_spill > 1GB:
-       reason = f"Spilling 较大: {spill_gb:.2f} GB"
-       suggestion = "检查内存配置或数据倾斜"
-   ```

-# 状态表优化指南
-
-本文档包含增量计算的状态表优化规则。
-
-这是增量优化的第二部分，基于增量算法分析的结果，提供具体的状态表优化建议。
-
-**前置依赖**：
-- 本文档的优化规则依赖于 [增量算法分析](./incremental-algorithm-analysis.md) 的结果
-- 必须先完成增量算法识别（4.2.1）才能应用这些优化规则
-
-**相关文档**：
-- [Stage/Operator 优化](./stage-operator-optimization.md) - Stage 和 Operator 级别优化
-- [增量算法分析](./incremental-algorithm-analysis.md) - 增量算法识别和分析（必读）
-- [优化原则](./optimization-principles.md) - 参数推荐原则

-## 状态表优化规则
-
-### 4.2.2 非增量原因诊断
-
-**触发条件**：
-- Job **非增量刷新**（根据 4.2.1 判断）
-
-**推荐操作**（根据版本选择）：
-
-#### 版本 <= 1.3
-
-**IF** job 非增量刷新 **AND** 版本 <= 1.3：
-```sql
--- 推荐设置以下 flag 后重新执行 EXPLAIN REFRESH
-set cz.optimizer.print.non.incremental.reason = true;
-set cz.optimizer.print.non.incremental.reason.msg.max.length = 100000;
-set cz.optimizer.incremental.force.incremental = true;
-```
-
-**THEN** 执行：
-```sql
-EXPLAIN REFRESH <表名>;
-```
-
-查看输出以了解为什么退化为全量刷新。
-
-#### 版本 >= 1.4
-
-**IF** job 非增量刷新 **AND** 版本 >= 1.4：
-```sql
--- 推荐设置以下 flag
-set cz.optimizer.incremental.try.incremental.refresh.enabled = true;
-```
-
-**THEN** 重新执行查询，系统会提示为什么没有走增量。
-
-**版本判断**：
-- 从 `plan.json` 的 `build_info` 或 `settings['build_info']` 中获取 `GitBranch` 信息
-- 例如：`GitBranch:release-v1.3` → 版本 1.3
-- 例如：`GitBranch:release-v1.4` → 版本 1.4

-### 4.2.3 Window 算子在 append-only delta 输入时的优化
-
-**目的**：优化 window 算子在 append-only delta 输入时的性能
-
-**⚠️ 重要前提**：
-- 根据 prompt 4.2.0 要求："同时关于状态表这些优化必须是对应算子的对应增量算法"
-- **只有带增量 hint 的 window 算子才需要分析**
-- 没有增量 hint 的 window 算子不是增量算法的一部分，应该跳过
-
-**检查步骤**：
-
-#### 步骤 0: 检查是否为增量算法的 window
-
-**首先检查 window 算子是否有增量相关的 hint**：
-```python
-def has_incremental_hint(op):
-    """检查是否有增量相关的 hint"""
-    op_str = json.dumps(op)
-    
-    incremental_patterns = [
-        'IncrementalLinearTopKWindowRule',
-        'IncrementalLinearTopKWindowRuleV2', 
-        'IncrementalWindowSetDeltaRule',
-        'Rule:Incremental',
-        'DeltaState',
-        'HINT=delta'
-    ]
-    
-    return any(pattern in op_str for pattern in incremental_patterns)
-
-# 只处理有增量 hint 的 window
-if not has_incremental_hint(window_op):
-    continue  # 跳过，不是增量算法的 window
-```
-
-**示例**：
-- ✅ **需要处理**：`HINT=delta,DeltaState-:[0,0]_IncrementalLinearTopKWindowRuleV2`
-- ❌ **跳过处理**：普通的 `PhysicalWindow([ROW_NUMBER()])` 没有增量 hint
-
-#### 步骤 1: 检查 window 算子的父节点
-
-检查 window 算子的父节点是否是 calc，且存在 `row number=1` 的 pattern。
-
-**rn=1 pattern 识别方法**：
-
-可以通过以下两种方式识别：
-
-1. **简单字符串匹配**（向后兼容）：
-   - 查找 'ROW_NUMBER', 'row_number', 'rn=1', 'rn = 1' 等字符串
-
-2. **JSON 结构匹配**（推荐）：
-   - 查找 EQ function，其中 constant.bigint = "1"
-   - EQ 表示等于 (=)，constant 有个值 bigint:1 表示是 1
-   - 所以对应的其实就是 xx=1
-
-**JSON 结构示例**：
-```json
-{
-  "function": {
-    "from": "",
-    "name": "EQ",
-    "builtIn": true,
-    "arguments": [
-      {
-        "reference": {
-          "id": "0",
-          "local": false,
-          "from": "",
-          "name": "",
-          "refType": "LOGICAL_FIELD"
-        },
-        "typeReference": 1
-      },
-      {
-        "constant": {
-          "bigint": "1"
-        },
-        "typeReference": 1
-      }
-    ],
-    "properties": {"properties": []},
-    "execDesc": "EQ(i64,i64)->b",
-    "functionProperties": {"properties": []}
-  },
-  "pt": {
-    "start": {"line": 1, "col": 7356, "pos": 7355},
-    "end": {"line": 1, "col": 7364, "pos": 7363}
-  },
-  "typeReference": 13
-}
-```
-
-**代码示例**：
-```python
-# 查找 window 算子
-for idx, op in enumerate(operators):
-    if 'window' in json.dumps(op).lower():
-        # 检查父节点（下游算子）
-        for parent_idx in range(idx + 1, len(operators)):
-            parent_op = operators[parent_idx]
-            if 'calc' in json.dumps(parent_op).lower():
-                # 方法1: 简单字符串匹配
-                parent_str = json.dumps(parent_op)
-                if 'ROW_NUMBER' in parent_str or 'rn=1' in parent_str or 'rn = 1' in parent_str:
-                    has_rn_pattern = True
-                    break
-
-                # 方法2: JSON 结构匹配（查找 EQ function with constant.bigint="1"）
-                if check_eq_one_pattern(parent_op):
-                    has_rn_pattern = True
-                    break
-```
-
-#### 步骤 2: 检查 window 的输入是否是 append-only delta
-
-使用 **4.2.1.5** 的方法检查 window 算子的输入是否是 append-only。
-
-从 window 算子向上游遍历，找到所有 TableScan：
-
-```python
-def check_append_only_input(window_idx):
-    visited = set()
-    append_only_tables = {}
-
-    def dfs(idx):
-        if idx in visited:
-            return
-        visited.add(idx)
-
-        op = operators[idx]
-
-        # 如果是 tablescan，检查是否是 append-only
-        if 'tableScan' in op:
-            table_scan = op['tableScan']
-            table_name = table_scan.get('table', {}).get('name', 'unknown')
-
-            # 检查实际输出的列（operator的schema），而不是表定义的完整schema
-            operator_schema = op.get('schema', {})
-            struct_info = operator_schema.get('structTypeInfo', {})
-            fields = struct_info.get('fields', [])
-            # 检查是否输出 __incremental_deleted 列（注意是过去式）
-            has_delete_col = any(f.get('name') == '__incremental_deleted' for f in fields)
-
-            if not has_delete_col:
-                # 是 append-only
-                append_only_tables[table_name] = True
-
-        # 继续向上游遍历
-        for input_idx in get_inputs(idx):
-            dfs(input_idx)
-
-    dfs(window_idx)
-    return len(append_only_tables) > 0, append_only_tables
-```
-
-#### 步骤 3: 优化建议
-
-检查 window 算子是否包含 `IncrementalLinearTopKWindowRule` hint：
-```python
-window_str = json.dumps(window_op)
-# 支持 V1 和 V2 版本的规则
-uses_linear_topk_rule = ('IncrementalLinearTopKWindowRule' in window_str or 
-                        'IncrementalLinearTopKWindowRuleV2' in window_str)
-```
-
-**IF** window 输入是 append-only **AND** 是 `rn=1` 的 pattern：
-
-**情况 1：已使用 IncrementalLinearTopKWindowRule**
-```python
-if uses_linear_topk_rule:
-    # 这是期望的行为，无需优化
-    print("Window 算子已正确使用 IncrementalLinearTopKWindowRule 增量算法")
-```
-
-**情况 2：未使用 IncrementalLinearTopKWindowRule**
-```python
-if not uses_linear_topk_rule:
-    # 需要优化：禁用竞争规则以启用 IncrementalLinearTopKWindowRule
-    param = 'cz.optimizer.incremental.window.sd.to.sd.rule.enable'
-    if param not in settings or settings.get(param) == 'true':
-        # 推荐设置
-        print("set cz.optimizer.incremental.window.sd.to.sd.rule.enable = false;")
-```
-
-**优化逻辑说明**：
-- `cz.optimizer.incremental.window.sd.to.sd.rule.enable=false` 禁用其他 window 规则
-- 这样可以让 `IncrementalLinearTopKWindowRule` 被选中使用
-- 只有在 append-only + rn=1 场景下且未使用 linear rule 时才推荐
-
-#### 步骤 4: 检查表 Property
-
-**IF** 输入表是 Append-only：
-
-检查 tablescan 的 table 属性是否有 `incr.append.only.table=true`：
-
-```python
-table_scan = op['tableScan']
-table_properties = table_scan.get('table', {}).get('properties', {})
-has_property = table_properties.get('incr.append.only.table') == 'true'
-```
-
-**IF** 没有设置：
-
-检查 job 是否有 flag `cz.optimizer.incremental.append.only.tables`：
-
-```python
-append_only_setting = settings.get('cz.optimizer.incremental.append.only.tables', '')
-if table_name not in append_only_setting:
-    # 缺少 append-only hint
-```
-
-**推荐**：
-```
-⚠️ 提醒用户添加：
-ALTER TABLE <表名> SET TBLPROPERTIES ('incr.append.only.table' = 'true');
--- 或
-set cz.optimizer.incremental.append.only.tables = '<表名>';
-```
-
----
-
-### 4.2.4 Append-only Scan 检查
-
-**目的**：检查当前 query 是否还包含 Append-only 的 scan，并预判算法是否最优
-
-**核心思想**：
-如果系统中仍然存在对 append-only 数据的扫描，说明可能没有充分利用 append-only 特性进行优化。理想情况下，append-only 数据应该通过增量算法处理，而不是重复扫描。
-
-**检查逻辑**：
-
-1. **识别 Append-only Delta 表**：
-   ```python
-   # 检查 TableScan 是否为 delta 表且不包含 __incremental_deleted 列（注意是过去式）
-   # 检查位置：算子的实际输出列（operator.schema.structTypeInfo.fields）
-   is_delta_table = (len(path) == 4 and path[-1] == '__delta__') or '__delta__' in table_name
-   operator_schema = op.get('schema', {})
-   struct_info = operator_schema.get('structTypeInfo', {})
-   cols = [f.get('name') for f in struct_info.get('fields', [])]
-   is_append_only = '__incremental_deleted' not in cols
-   ```
-
-2. **分析优化机会**：
-   
-   **IF** 发现 Append-only scan **AND** 有 Join/Aggregate 操作：
-   
-   a) **状态表检查**：
-   ```python
-   state_table_enabled = settings.get('cz.optimizer.incremental.enable.state.table', 'false') == 'true'
-   if not state_table_enabled:
-       # 建议：考虑启用状态表以避免重复扫描 append-only 数据
-   ```
-   
-   b) **增量算法检查**：
-   ```python
-   has_incremental_hints = any(pattern in plan_str for pattern in [
-       'IncrementalLinearTopKWindowRule',
-       'IncrementalAggregateRule', 
-       'IncrementalJoinRule',
-       'Rule:Incremental',
-       'DeltaState'
-   ])
-   if not has_incremental_hints:
-       # 建议：可能可以使用增量计算替代全量扫描
-   ```
-   
-   c) **综合评估**：
-   ```python
-   if not has_incremental_hints and not state_table_enabled:
-       # 建议：append-only 数据特性未被充分利用，建议使用增量处理
-   ```
-
-**优化建议逻辑**：
-
-- **问题**：为什么还在扫描 append-only 数据？
-- **期望**：append-only 数据应该通过增量算法高效处理
-- **建议**：
-  1. 启用状态表避免重复扫描
-  2. 使用增量算法替代全量扫描  
-  3. 充分利用 append-only 数据特性
-
-**示例输出**：
-```
-💡 Stage stg11: 表 ws1.namespace.table_a 是 append-only
-[INFO] POTENTIAL_OPTIMIZATION - Stage stg11
-       append-only 表 ws1.namespace.table_a 仍在进行扫描，
-       考虑启用状态表以避免重复扫描 append-only 数据; 
-       未检测到增量算法 hint，可能可以使用增量计算替代全量扫描; 
-       append-only 数据特性未被充分利用，建议使用增量处理
-```
-
----
-
-### 4.2.5 状态表启用建议
-
-**目的**：判断是否应该开启状态表以优化增量计算
-
-**规则类型**：GlobalRule（全局规则，只执行一次）
-
-**执行时机**：在"阶段2: 全局规则分析"中执行，不针对单个stage，而是分析整个job
-
-**检查步骤**：
-
-#### 步骤 1: 检查是否包含中间状态表
-
-在整个 job 的所有 stage 中搜索表名包含 `__incr__` pattern 的 TableSink。
-
-```python
-def _check_job_has_state_table(context):
-    """检查整个 job 是否已经包含中间状态表"""
-    aligned_stages = context.get('aligned_stages', {})
-    
-    # 检查所有 stage 的 plan
-    for stage_id, stage_data in aligned_stages.items():
-        plan = stage_data.get('plan', {})
-        plan_str = json.dumps(plan)
-        if '__incr__' in plan_str:
-            return True
-            
-    return False
-```
-
-**IF** 已包含中间状态表：
-- 无需进一步检查
-- 输出：`Job 已包含中间状态表（表名包含 __incr__）`
-
-**注意**：此检查是全局的，不仅检查当前 stage，而是检查整个 job 的所有 stage。这避免了在某些 stage 中状态表已存在但其他 stage 仍建议开启状态表的误判。
-
-#### 步骤 2: 判断是否值得存储中间状态
-
-**考虑因素**：
-
-1. **是否需要状态**（参考流计算的带状态计算定义）：
-   - 有聚合计算（SUM, COUNT, MIN, MAX）
-   - 有 Window 函数
-   - 有 JOIN（需要保存 Join 状态）
-
-   **重要**：只检查增量算法产生的算子，根据 prompt 4.2.1.2 要求：
-   ```python
-   def _get_incremental_stateful_ops(plan):
-       """获取增量算法产生的状态算子列表"""
-       incremental_stateful_ops = []
-       operators = plan.get('operators', [])
-       
-       for op in operators:
-           # 检查是否有增量 hint
-           if not _has_incremental_hint(op):
-               continue
-               
-           # 检查算子类型并匹配对应的增量算法
-           op_str = json.dumps(op)
-           
-           # Join 算子：检查是否有对应的 Join 增量算法
-           if ('Join' in op_str or 'HashJoin' in op_str) and 'Join' not in incremental_stateful_ops:
-               join_patterns = [
-                   'IncrementalJoinRule',
-                   'Rule:Incremental.*Join',
-                   'Rule:DeletePlan-delta-join'
-               ]
-               if any(pattern in op_str for pattern in join_patterns):
-                   incremental_stateful_ops.append('Join')
-           
-           # Aggregate 算子：检查是否有对应的 Aggregate 增量算法
-           elif ('HashAggregate' in op_str or 'Aggregate' in op_str) and 'HashAggregate' not in incremental_stateful_ops:
-               agg_patterns = [
-                   'IncrementalAggregateRule',
-                   'IncrementalLinearFunctionAggregateRule',
-                   'Rule:Incremental.*Aggregate',
-                   'Rule:Incremental.*Agg'
-               ]
-               if any(pattern in op_str for pattern in agg_patterns):
-                   incremental_stateful_ops.append('HashAggregate')
-           
-           # Window 算子：检查是否有对应的 Window 增量算法
-           elif ('Window' in op_str or 'HashWindow' in op_str) and 'Window' not in incremental_stateful_ops:
-               window_patterns = [
-                   'IncrementalLinearTopKWindowRule',
-                   'IncrementalLinearTopKWindowRuleV2',
-                   'IncrementalWindowSetDeltaRule',
-                   'Rule:Incremental.*Window'
-               ]
-               if any(pattern in op_str for pattern in window_patterns):
-                   incremental_stateful_ops.append('Window')
-       
-       return incremental_stateful_ops
-
-   if not incremental_stateful_ops:
-       # 不包含增量算法产生的状态算子，无需开启状态表
-       return
-   ```
-
-   **新增要求**：需要区分增量算法是不是对应的增量算法，如：
-   - Join 算子对应的 rule 是 join 相关的增量算法
-   - Aggregate 算子对应的 rule 是 aggregate 相关的增量算法  
-   - Window 算子对应的 rule 是 window 相关的增量算法
-   - 除非是第一次出现 hint 的 operator，否则应该都有对应关系
-   - 不要错误把一些增量算法的中间算子当作自己本身
-   
-   **重要**：使用 `elif` 确保每个算子只能匹配一种类型，避免一个算子被错误地归类为多种类型。例如，一个 Join 算子如果有 Aggregate 相关的 rule，不应该被当作 Aggregate 算子处理。
-
-#### 步骤 3: 两个正交的状态表优化策略
-
-**策略1：基于增量算法的状态表优化**
-- 通过程序级别的参数控制是否启用，不依赖被分析job的参数
-- 控制方式：
-  - 调用时传入：`context['enable_incremental_algorithm_analysis'] = True`
-  - 环境变量：`ENABLE_INCREMENTAL_ALGORITHM_ANALYSIS=true`
-  - 配置文件：`analysis.enable_incremental_algorithm = true`
-  - 命令行参数：`--enable-incremental-algorithm`
-- 默认不启用，避免浪费分析时间
-- 检查是否包含增量算法产生的状态算子（HashAggregate, Window, Join）
-
-**策略2：基于Snapshot Subplan占比的状态表优化（最重要）**
-- **核心原理**：中间表之所以要创建不就是因为它计算的subplan是类似跑了全量，所以才需要的，这个是最重要的
-- 总是执行，因为这是最重要的判断依据
-- 基于operator级别的链路关系，不是stage级别
-- 结合3.6的operator统计和4.2.1的delta/snapshot分析
-- 找到某个subplan（root节点是snapshot）的统计耗时占比
-
-**程序级别控制示例**：
-```bash
-# 方式1：命令行参数控制（推荐）
-python analyze_job.py plan.json job_profile.json --enable-incremental-algorithm
-
-# 方式2：同时启用状态表分析和增量算法策略
-python analyze_job.py plan.json job_profile.json --enable-state-table --enable-incremental-algorithm
-
-# 方式3：只启用状态表分析（不启用增量算法策略）
-python analyze_job.py plan.json job_profile.json --enable-state-table
-```
-
-**参数传递链路**：
-```
-命令行参数 --enable-incremental-algorithm
-    ↓
-analyze_job.py 中的 enable_incremental_algorithm_analysis 参数
-    ↓
-context['enable_incremental_algorithm_analysis'] = True
-    ↓
-StateTableEnable.analyze() 中读取并控制策略启用
-```
-
-**代码实现**：
-```python
-# analyze_job.py
-def analyze_job(plan_file, profile_file, output_dir=".", 
-               enable_state_table_analysis=False,
-               enable_incremental_algorithm_analysis=False):
-    # ...
-    analyzer.context['enable_incremental_algorithm_analysis'] = enable_incremental_algorithm_analysis
-
-# state_table_enable.py  
-def analyze(self, stage_data, context):
-    enable_incremental_strategy = context.get('enable_incremental_algorithm_analysis', False)
-    if enable_incremental_strategy:
-        # 执行增量算法策略分析
-        pass
-```
-
-**重要说明**：
-- 这是分析程序自己的控制参数，不是被分析job的参数
-- 不会推荐用户设置新的job参数（遵循prompt第8条）
-- 只推荐已知有效的job参数：`cz.optimizer.incremental.enable.state.table=true`
-
-**Snapshot Subplan分析逻辑**：
-```python
-def _find_snapshot_subplans(operator_data_types, operator_analysis, context):
-    """
-    找到root节点是snapshot的subplan
-    
-    1. 结合3.6的operator统计和4.2.1的delta/snapshot分析
-    2. 基于operator级别的链路关系，不是stage级别  
-    3. 找到某个subplan（root节点是snapshot）的统计耗时占比
-    """
-    # 找到所有snapshot类型的operator作为潜在的root节点
-    snapshot_operators = [op_id for op_id, data_type in operator_data_types.items() 
-                         if data_type == 'snapshot']
-    
-    # 获取operator依赖关系（来自增量算法分析器）
-    operator_dependencies = _get_operator_dependencies(context)
-    
-    subplans = []
-    for root_op in snapshot_operators:
-        # 从root节点开始，找到整个snapshot subplan
-        subplan_ops = _trace_snapshot_subplan(root_op, operator_data_types, operator_dependencies)
-        
-        # 计算subplan的总耗时占比
-        total_time_ms = sum(op_time_map[op_id]['elapsed_ms'] for op_id in subplan_ops)
-        percentage = (total_time_ms / total_job_time * 100)
-        
-        if percentage >= 15.0:
-            # 推荐创建中间状态表
-            pass
-    
-    return subplans
-```
-
-**策略执行逻辑**：
-```python
-def analyze_global(self, context: Dict) -> Dict:
-    """全局分析：分析整个job的snapshot subplan（只执行一次）"""
-    
-    # 策略1：基于增量算法的状态表优化（程序控制是否启用）
-    enable_incremental_strategy = context.get('enable_incremental_algorithm_analysis', False)
-    if enable_incremental_strategy:
-        incremental_result = self._analyze_incremental_algorithm_strategy_global(context)
-        # 合并结果
-    
-    # 策略2：基于Snapshot subplan占比的状态表优化（总是执行，最重要）
-    snapshot_result = self._analyze_snapshot_subplan_strategy(context)
-    # 合并结果
-    
-    return results
-```
-
-**关键改进（2024年修复）**：
-1. **全局分析**：StateTableEnable 改为 GlobalRule，只执行一次，不是每个stage执行一次
-2. **公共节点处理**：对于全snapshot的subplan，公共节点也属于subplan（不跳过processed_operators）
-3. **具体物化信息**：输出具体的root节点和所在stage，如"建议在 Stage stg18 的算子 HashJoin27 处物化为中间状态表"
-4. **详细日志**：每个subplan都打印完整信息（序号、root、stage、占比、算子数量、决策）
-
-**日志输出示例**：
-```
-[INFO] [StateTableEnable] 开始全局分析
-[INFO] [StateTableEnable] Snapshot策略 - 找到 5 个 snapshot subplan
-
-[INFO] Snapshot策略 - Subplan 1/5: Root=HashJoin27 (Stage stg18), 占比=28.9% (52468ms / 181357ms), 包含13个算子
-[INFO] Snapshot策略 - ✓ Subplan 1 占比 28.9% >= 15%，建议在 Stage stg18 的算子 HashJoin27 处物化为中间状态表
-
-[INFO] Snapshot策略 - Subplan 2/5: Root=HashJoin154 (Stage stg14), 占比=6.8% (12389ms / 181357ms), 包含12个算子
-[INFO] Snapshot策略 - ✗ Subplan 2 占比 6.8% < 15%，不建议创建状态表
-
-[INFO] [StateTableEnable] 全局分析完成: 总共 1 findings, 1 recommendations
-```
-
-**输出示例**：
-```
-[增量策略] 包含 HashAggregate，状态表大小预估合理，建议开启状态表以避免重复计算
-[Snapshot策略] 发现高占比subplan (18.5%)：Aggregate(SUM,COUNT, 1200ms) -> Join(INNER, 800ms) -> TableScan(ws1.test_table, 500ms)
-```
-
-**Snapshot 骨架输出**：
-- 同时打印出该 snapshot 的"骨架"，即把重要算子打印出来，如 aggregate/join/window/tablescan
-- aggregate 打印出聚集函数，window 类似
-- 这样方便从原始 sql 找到对应的 sql，这样 join 等就知道是从哪个 tablescan 开始到哪里结束需要创建中间表

-
-   **增量 hint 检查**：
-   ```python
-   def _has_incremental_hint(op):
-       """检查算子是否有增量相关的 hint"""
-       op_str = json.dumps(op)
-       incremental_patterns = [

-           'IncrementalWindowSetDeltaRule',
-           'IncrementalAggregateRule',
-           'IncrementalJoinRule',
-           'Rule:Incremental',

-           if pattern in op_str:
-               return True
-       return False
-   ```
-
-2. **状态表是否会过大**：
-   - 根据每一步的 stats 信息（inputBytes, outputBytes）
-   - 根据输入表的增量数据大小
-   - 判断状态表大小是否可接受
-
-   ```python
-   output_bytes = metrics.get('output_bytes', 0)
-   input_bytes = metrics.get('input_bytes', 0)
-
-   if input_bytes == 0:
-       # 无法判断，保守建议开启
-       should_enable = True
-   else:
-       size_ratio = output_bytes / input_bytes
-       STATE_SIZE_RATIO_THRESHOLD = 10  # 阈值
-
-       if size_ratio > STATE_SIZE_RATIO_THRESHOLD:
-           # 状态表可能过大
-           should_enable = False
-           reason = f"状态表可能过大（输出/输入比例={size_ratio:.1f}x，阈值={STATE_SIZE_RATIO_THRESHOLD}x）"
-       else:
-           # 状态表大小合理
-           should_enable = True
-           reason = f"包含 {', '.join(stateful_ops)}，状态表大小预估合理（输出/输入比例={size_ratio:.1f}x）"
-   ```
-
-#### 步骤 3: 推荐参数
-
-**IF** 不包含状态表 **AND** 值得存储中间状态：
-
-搜索 settings 中 `cz.optimizer.incremental.enable.state.table`：
-
-**IF** 参数不存在 **OR** 值 = `false`：
-```sql
--- 推荐
-set cz.optimizer.incremental.enable.state.table = true;
-```
-
-**附加说明**：
-```
-状态表大小预估: <size> GB
-增量数据大小: <delta_size> GB
-建议: 开启状态表可以避免重复计算
-```

-### 4.2.6 Aggregate 复用检查
-
-**目的**：检查 Aggregate 计算是否利用了之前的计算结果
-
-**期望行为**：
-- **SUM, COUNT**: 无论如何都应尽量使用之前的结果
-- **MIN, MAX**: 在 Append-only 情况下应尽量使用之前的结果
-
-**检查步骤**：
-
-#### 步骤 1: 找到原始 SQL 的 Aggregate operator
-
-**重要**：aggregate 必须设置上了 hint 包含类似 4.2.1.2 的一些状态 hint。
-
-如果不包含，说明该 aggregate 算子不是原始 sql 中的 aggregate，而是其他优化器 rule 等自己生成的，这些不需要检查。
-
-```python
-def has_incremental_hint(op):
-    """检查算子是否有增量 hint"""
-    op_str = json.dumps(op)
-
-    # 检查是否包含增量相关的 Rule hint
-    incremental_patterns = [
-        'IncrementalLinearFunctionAggregateRule',
-        'IncrementalAggPositiveDeltaDedupRule',
-        'IncrementalAggregate',
-        'Rule:Incremental.*Aggregate',
-        'Rule:Incremental.*Agg'
-    ]
-
-    for pattern in incremental_patterns:
-        if pattern in op_str:
-            return True
-
-    return False
-
-# 过滤掉增量算法的辅助 aggregate
-for op in stage['operators']:
-    if 'hashAgg' in op or 'hashAggregate' in op:
-        # 检查是否是辅助 aggregate（P1/P2 阶段）
-        if is_incremental_helper_aggregate(op):
-            continue
-
-        # 检查是否有增量 hint
-        if not has_incremental_hint(op):
-            continue  # 不是原始 SQL 的 aggregate
-
-        # 提取 aggregate 函数
-        agg_calls = op['hashAgg']['aggregate']['aggregateCalls']
-        for call in agg_calls:
-            func_name = call['function']['function']['name']
-            # 检查是否是 SUM, COUNT, MIN, MAX
-```
-
-#### 步骤 2: 检查是否利用了之前的计算结果
-
-在 Aggregate 的 properties 或上游 Scan 中查找增量计算相关标识。
-
-```python
-def check_incremental_markers(plan):
-    """检查是否有增量标记"""
-    plan_str = json.dumps(plan).lower()
-    return any(m in plan_str for m in ['incremental', 'delta', 'state', 'partial_result'])
-
-has_incremental_marker = check_incremental_markers(plan)
-```
-
-**IF** 发现没有复用之前的结果：
-
-#### 步骤 3: 检查是否存在状态
-
-使用 **4.2.5** 的方法检查状态表。
-
-```python
-def check_state_table_exists(plan):
-    """检查是否存在状态表"""
-    plan_str = json.dumps(plan)
-    return '__incr__' in plan_str
-
-has_state_table = check_state_table_exists(plan)
-```
-
-**IF** 状态不存在：
-```
-⚠️ 建议：可能缺少状态表，建议设置 cz.optimizer.incremental.enable.state.table=true
-```
-
-#### 步骤 4: 检查是否有 Append-only 输入
-
-使用 **4.2.1.5** 的方法检查 aggregate 的输入是否是 append-only。
-
-```python
-def check_append_only_inputs(plan, agg_idx):
-    """检查 aggregate 的输入是否是 append-only"""
-    # 从 aggregate 向上游遍历，找到所有 tablescan
-    # 检查实际输出的列（operator.schema.structTypeInfo.fields）
-    # 检查是否输出 __incremental_deleted 列（注意是过去式）
-    # 如果没有输出，则是 append-only
-    pass
-
-is_append_only = check_append_only_inputs(plan, agg_idx)
-```
-
-**IF** 是 Append-only **BUT** 缺少系统 hint：
-
-```
-⚠️ 建议补充 hint:
-ALTER TABLE <表名> SET TBLPROPERTIES ('incr.append.only.table' = 'true');
--- 或
-set cz.optimizer.incremental.append.only.tables = '<表名>';
-```
-
-#### 步骤 5: 分析不同聚集函数
-
-**对于 SUM, COUNT**：
-- 无论如何都应该使用之前的结果
-- 如果没有复用，给出 WARNING 级别的 finding
-
-**对于 MIN, MAX**：
-- 在 append-only 情况下应该使用之前的结果
-- 如果是 append-only 但没有复用，给出 INFO 级别的 finding
-
-**示例输出**：
-```
-发现 Aggregate: SUM(amount)
-检查: 没有利用之前的计算结果
-原因: 输入表 orders 是 Append-only 但缺少 hint
-建议: 添加 'incr.append.only.table' = 'true' property
-```

-### 4.2.7 Calc 状态优化
-
-**触发条件**（必须**全部**满足）：
-1. Calc operator 占其所属 Stage 耗时 **> 30%**
-2. 该 Stage 占整体耗时 **> 10%**
-
-**检查步骤**：
-
-#### 步骤 1: 识别高耗时 Calc
-
-```python
-for op in operator_analysis:
-    if 'Calc' in op['operator_id']:
-        if op['stage_pct'] > 30 and stage_total_pct > 10:
-            # 触发优化检查
-```
-
-#### 步骤 2: 分析 Calc 内容
-
-在 plan 中查看 Calc operator 的详细内容：
-
-```python
-calc_op = find_operator(plan, 'calc')
-expressions = calc_op['calc']['expressions']
-
-# 检查是否有高成本函数
-for expr in expressions:
-    if is_udf(expr) or is_complex_function(expr):
-        has_heavy_calc = True
-```
-
-#### 步骤 3: 特别关注 UDF
-
-**IF** Calc 包含**用户自定义函数（UDF）**：
-- UDF 通常耗时较长
-- 非常适合通过状态表优化
-
-#### 步骤 4: 推荐参数
-
-**IF** 发现高耗时 Calc（特别是包含 UDF）：
-
-搜索 settings 中 `cz.optimizer.incremental.create.rule.based.table.on.heavy.calc`：
-
-**IF** 参数不存在 **OR** 值 = `false`：
-```sql
--- 推荐
-set cz.optimizer.incremental.create.rule.based.table.on.heavy.calc = true;
-```
-
-**示例输出**：
-```
-发现高耗时 Calc: Calc25
-  Stage 占比: 45.2%
-  整体占比: 12.3%
-  包含 UDF: my_custom_transform()
-建议: 开启 Calc 状态优化
-  set cz.optimizer.incremental.create.rule.based.table.on.heavy.calc = true;
-```
-
-#### 步骤 5: 显示所有满足的优化模式
-
-**重要**：总体所有满足这些优化 pattern 的（4.2.3-4.2.7），请可以显示出来，提供查看。
-
-这包括：
-- 4.2.3: Window 算子在 append-only delta 输入时的优化机会
-- 4.2.4: 基于 append-only scan 的优化机会
-- 4.2.5: 中间状态表创建的优化机会
-- 4.2.6: Aggregate linear rule 优化机会
-- 4.2.7: Calc 状态优化机会
-
-**输出格式**：
-```
-优化机会总览：
-1. [Window优化] Stage 3: Window 算子输入是 append-only 且有 rn=1 pattern
-2. [状态表优化] Stage 5: Aggregate SUM/COUNT 可以利用状态表
-3. [Calc优化] Stage 7: Calc 包含 UDF，占比 45.2%
-...

-# Dynamic Table 列校验与一致性规则
-
-你是一个 SQL 转换专家。在生成 Dynamic Table DDL 后，需要校验 schema 定义的列与 SELECT 查询产出的列是否一致。
-
-## 列数校验（必须通过）
-
-### 规则
-
-生成的 DDL 中，括号内定义的列数必须等于 AS 后面 SELECT 查询产出的列数。
-
-```sql
-CREATE OR REPLACE DYNAMIC TABLE t (
-    col1 BIGINT,    -- 1
-    col2 STRING,    -- 2
-    dt STRING       -- 3  → schema 列数 = 3
-)
-AS
-SELECT col1, col2, '2024-01-01' AS dt  -- → SELECT 列数 = 3 ✓
-FROM source;
-```
-
-### SELECT 列数计算
-
-1. 找到 AS 后面的 SELECT 子句
-2. 找到顶层 FROM（不在子查询/括号内的 FROM）
-3. 计算 SELECT 和 FROM 之间的顶层逗号数 + 1 = 列数
-4. 顶层逗号：不在括号 `()`、方括号 `[]`、引号 `''`/`""` 内的逗号
-
-### UNION ALL 的列数
-
-取第一个分支的列数（所有分支列数应一致）。
-
-### 校验失败
-
-如果 schema 列数 ≠ SELECT 列数，转换失败，报错：
-```
-Schema列数(N) != SELECT列数(M)
-```
-
-## 列名校验（可选）
-
-### 规则
-
-逐位对比 schema 中的列名与 SELECT 中推断出的别名。建议在列数校验通过后，如果 SELECT 中大部分列都有明确别名（AS 或裸标识符），开启列名校验做二次确认。
-
-### SELECT 列别名推断
-
-按优先级从高到低：
-
-1. **AS 别名**：`expression AS alias` → 别名为 `alias`
-2. **末尾标识符**：`table.column` → 别名为 `column`
-3. **裸标识符**：`column_name` → 别名为 `column_name`
-4. **无法推断**：`func(a, b)` 没有 AS → 标记为 `<expr>`，跳过校验
-
-### 对比规则
-
-- 逐位对比（第1列对第1列，第2列对第2列...）
-- 如果某位是 `<expr>`（无法推断），跳过该位
-- 对比不区分大小写
-- 不匹配时报错并列出具体不对齐的列
-
-## 静态分区注入后的列数
-
-注入静态分区列后，SELECT 列数会增加。校验应在注入后进行。
-
-### 避免重复注入
-
-在注入前检查 SELECT 中是否已包含该分区列：
-
-1. 解析 SELECT 中每个表达式的最终别名
-2. 如果别名（不区分大小写）与分区列名匹配 → 该列已存在，跳过注入
-3. 只注入 SELECT 中不存在的分区列
-
-## UNION ALL 一致性
-
-### 分支列数一致性
-
-所有 UNION ALL 分支的列数必须相同。如果不一致，记录警告：
-```
-UNION分支列数不一致: [12, 13, 12]
-```
-
-### 注入后复核
-
-静态分区注入后，再次检查各分支列数是否一致：
-```
-注入后UNION各分支列数: [13, 13, 13]
-```
-
-## 重复别名检测
-
-如果 SELECT 中有重复的列别名，记录警告：
-```
-检测到重复列别名: ['dt']
-```
-
-重复别名可能导致：
-- 列数看起来正确但实际语义错误
-- 下游查询引用歧义
-
-## 缺失分区列检测
-
-如果 SELECT 中缺少某些分区列（注入前），记录信息：
-```
-检测到缺失分区列: ['dt', 'ds']
-```
-
-这些列会在注入步骤中被自动添加。
-
-## 完整校验流程
-
-```
-1. 生成 DDL（含静态分区注入）
-2. 提取 schema 列数
-3. 提取 SELECT 列数
-4. 比较列数 → 不等则失败
-5. （可选）逐位对比列名 → 不匹配则失败
-```

-# SQL → Dynamic Table 转换规则
-
-你是一个 SQL 转换专家。给定一个 Hive/Spark SQL 的 CREATE TABLE DDL 和对应的 INSERT OVERWRITE 语句，你需要按以下规则将它们合并为一个 Dynamic Table DDL。
-
-## 总体转换公式
-
-```
-输入1: CREATE TABLE schema.table_name (...) PARTITIONED BY (...) ...
-输入2: INSERT OVERWRITE TABLE schema.table_name PARTITION(...) SELECT ... FROM ...
-输出:  CREATE OR REPLACE DYNAMIC TABLE schema.table_name (...) PARTITIONED BY (...) ... AS SELECT ... FROM ...
-```
-
-核心思想：把 CREATE TABLE 的结构定义 + INSERT OVERWRITE 的查询逻辑，合并成一个 `CREATE OR REPLACE DYNAMIC TABLE ... AS SELECT ...` 语句。
-
-## 第一步：解析 CREATE TABLE DDL
-
-从 DDL 中提取以下信息：
-
-1. **表名**（含 schema）：`schema.table_name`
-2. **普通列**：列名、数据类型、COMMENT（保持原始缩进格式）
-3. **分区列**：PARTITIONED BY 中的列名、数据类型、COMMENT
-4. **存储格式**：STORED AS PARQUET/ORC/AVRO 等
-5. **表属性**：TBLPROPERTIES 或 WITH PROPERTIES 中的键值对
-6. **分桶信息**：CLUSTERED BY / SORTED BY / RANGE CLUSTERED BY / HASH CLUSTERED BY
-7. **生命周期**：LIFECYCLE N
-8. **连接信息**：CONNECTION schema.connection_name
-9. **位置信息**：LOCATION 'path'
-
-## 第二步：解析 INSERT OVERWRITE 语句
-
-从 INSERT 语句中提取：
-
-1. **目标表名**：用于自引用检测
-2. **分区类型**：
-   - 动态分区：`PARTITION (col1, col2)` — 列名无值
-   - 静态分区：`PARTITION (col1='value1', col2=value2)` — 列名有值
-   - 混合分区：`PARTITION (static_col='value', dynamic_col)` — 部分有值
-3. **SELECT 查询**：完整的查询逻辑（含 WHERE、JOIN、GROUP BY 等）
-4. **CTE（WITH 子句）**：如果有，保留完整的 WITH ... AS (...) 结构
-5. **前置语句**：SET 语句、CREATE TEMPORARY FUNCTION 等（保留）
-
-### 需要过滤的语句
-
-从 INSERT 文件中移除：
-- `ALTER TABLE ... ADD PARTITION ...`
-- `ALTER TABLE ... DROP PARTITION ...`
-- 所有 `ALTER TABLE` 开头的语句
-- `ANALYZE TABLE` 语句
-- SQL 注释（`--` 和 `/* */`）
-
-## 第三步：组装 Dynamic Table DDL
-
-按以下顺序组装输出：
-
-```sql
--- 可选：如果需要删除已存在的同名表，请取消下一行的注释
--- DROP TABLE IF EXISTS schema.table_name;
-
-CREATE SCHEMA IF NOT EXISTS schema;        -- 仅当表名含 schema 时
-CREATE OR REPLACE DYNAMIC TABLE schema.table_name (
-    col1 BIGINT COMMENT '...',             -- 普通列（保持原始格式）
-    col2 STRING COMMENT '...',
-    part_col1 STRING COMMENT '...'         -- 分区列追加在普通列后面
-)
-PARTITIONED BY (part_col1, part_col2)      -- 仅列名，不含类型
-[CLUSTERED BY (...) [SORTED BY (...)] [INTO N BUCKETS]]
-[STORED AS PARQUET]
-TBLPROPERTIES ('key' = 'value')            -- 合并模板属性和原始属性
-[LIFECYCLE N]
-[CONNECTION schema.connection_name]
-[LOCATION 'original_path_dt']             -- 原路径加 _dt 后缀
-AS
-SELECT查询;                                -- 来自 INSERT OVERWRITE 的查询
-```
-
-### 关键规则
-
-1. **列定义**：普通列 + 分区列合并到一个括号内，保持原始缩进
-2. **PARTITIONED BY**：只写列名，不写类型（与 CREATE TABLE 不同）
-3. **CREATE SCHEMA**：如果表名含 `.`（如 `kscdm.table_name`），在 DDL 前加 `CREATE SCHEMA IF NOT EXISTS kscdm;`
-4. **LOCATION**：原路径加 `_dt` 后缀
-5. **DROP 语句**：注释掉的 `DROP TABLE IF EXISTS` 放在最前面
-
-## 第四步：静态分区注入
-
-当 INSERT OVERWRITE 使用静态分区（`PARTITION(col=value)`）时，需要将分区值注入到 SELECT 子句中。
-
-### 注入规则
-
-在 SELECT 的最后一个列之后、FROM 之前，按 DDL 中分区列的定义顺序追加：
-
-```sql
--- 原始 SELECT
-SELECT col1, col2 FROM source_table
-
--- 注入后（假设 PARTITION(year=2024, month='January')）
-SELECT col1, col2,
-    2024 AS year,
-    'January' AS month
-FROM source_table
-```
-
-### 值类型智能处理
-
-注入时根据值的类型决定是否加引号：
-
-| 值类型 | 判断规则 | 处理 | 示例 |
-|--------|----------|------|------|
-| 已有引号 | 以 `'` 或 `"` 开头结尾 | 保持原样 | `'hello'` → `'hello'` |
-| NULL | 值为 `NULL`（不区分大小写） | 不加引号 | `NULL` |
-| 布尔值 | `true` / `false`（不区分大小写） | 不加引号 | `true` |
-| 数字 | 可被 `float()` 解析 | 不加引号 | `123`, `-45.67`, `1.23e-4` |
-| SESSION_CONFIGS | 包含 `SESSION_CONFIGS(` | 不加引号 | `SESSION_CONFIGS()['dt.args.ds']` |
-| 函数调用 | 匹配 `标识符(...)` 且括号平衡 | 不加引号 | `CURRENT_DATE()`, `YEAR(col)` |
-| 字符串 | 以上都不匹配 | 加单引号，内部 `'` 转义为 `''` | `hello` → `'hello'` |
-
-### UNION ALL 处理
-
-如果 SELECT 包含 UNION ALL，每个分支都要独立注入分区列：
-
-```sql
-SELECT col1, col2,
-    2024 AS year
-FROM table_a
-UNION ALL
-SELECT col1, col2,
-    2024 AS year
-FROM table_b
-```
-
-### CTE + UNION ALL
-
-如果有 WITH 子句，先分离 CTE 部分，只对主查询中的 UNION 分支注入。
-
-### 已存在的分区列
-
-如果 SELECT 中已经包含了某个分区列（通过 `AS alias` 或末尾标识符检测），则跳过该列的注入，避免重复。
-
-## 第五步：日期函数后处理
-
-生成 DDL 后，对整个 DDL 文本做一次全局替换：
-
-| 原始形式 | 替换为 |
-|----------|--------|
-| `DATE_SUB(expr, INTERVAL N DAY)` | `sub_days(expr, N)` |
-| `DATE_ADD(expr, INTERVAL N DAY)` | `sub_days(expr, -N)` |
-
-这一步确保最终输出统一使用 `sub_days` 函数。
-
-> 注意：在 SQL 引擎中，`SUB_DAYS` 是 `DATE_SUB` 的别名，两者等价。统一使用 `sub_days` 是为了保持输出一致性。
-
-## 第六步：表属性模板合并
-
-默认模板属性：`data_lifecycle = 15`
-
-合并规则：
-- 模板属性作为基础
-- 原始 DDL 中的 TBLPROPERTIES 覆盖同名模板属性
-- 最终结果写入 TBLPROPERTIES
-
-```sql
--- 模板: data_lifecycle=15
--- 原始DDL: TBLPROPERTIES('compression'='snappy', 'data_lifecycle'='30')
--- 合并结果:
-TBLPROPERTIES ('data_lifecycle' = '30', 'compression' = 'snappy')
--- data_lifecycle 保留原始值 30，compression 来自原始DDL
-```
-
-## 完整示例
-
-### 输入1：DDL
-```sql
-CREATE TABLE IF NOT EXISTS sales_data (
-    id BIGINT COMMENT '销售记录ID',
-    product_name STRING COMMENT '产品名称',
-    sales_amount DECIMAL(12,2) COMMENT '销售金额'
-)
-PARTITIONED BY (
-    year INT COMMENT '年份',
-    month INT COMMENT '月份'
-)
-STORED AS PARQUET
-LOCATION '/data/warehouse/sales_data';
-```
-
-### 输入2：INSERT OVERWRITE
-```sql
-INSERT OVERWRITE TABLE sales_data
-PARTITION (year, month)
-SELECT
-    s.id,
-    s.product_name,
-    s.price * s.quantity AS sales_amount,
-    YEAR(s.sales_date) AS year,
-    MONTH(s.sales_date) AS month
-FROM raw_sales s
-WHERE s.status = 'completed';
-```
-
-### 输出：Dynamic Table DDL
-```sql
--- 可选：如果需要删除已存在的同名表，请取消下一行的注释
--- DROP TABLE IF EXISTS sales_data;
-
-CREATE OR REPLACE DYNAMIC TABLE sales_data (
-    id BIGINT COMMENT '销售记录ID',
-    product_name STRING COMMENT '产品名称',

-# SQL 占位符 → SESSION_CONFIGS() 转换规则
-
-你是一个 SQL 转换专家。在将传统 SQL 转换为 Dynamic Table SQL 时，需要将各种占位符格式统一转换为 `SESSION_CONFIGS()` 函数调用。
-
-## 占位符格式统一
-
-首先将所有旧格式统一为 `${...}` 格式：
-
-| 旧格式 | 统一为 |
-|--------|--------|
-| `{{ var }}` | `${var}` |
-| `{{ ds }}` | `${ds}` |
-| `{{region}}` | `${region}` |
-
-转换正则：`\{\{\s*([^}]+)\s*\}\}` → `${\1}`
-
-## 基本替换规则
-
-### 简单变量
-
-| 输入 | 输出 |
-|------|------|
-| `${ds}` | `SESSION_CONFIGS()['dt.args.ds']` |
-| `${region}` | `SESSION_CONFIGS()['dt.args.region']` |
-| `${hour}` | `SESSION_CONFIGS()['dt.args.hour']` |
-
-### nodash 变量（特殊处理）
-
-变量名中包含 `nodash` 时，自动包装 DATE_FORMAT，但变量名保持原样：
-
-| 输入 | 输出 |
-|------|------|
-| `${ds_nodash}` | `DATE_FORMAT(SESSION_CONFIGS()['dt.args.ds_nodash'], 'yyyyMMdd')` |
-| `${dsnodash}` | `DATE_FORMAT(SESSION_CONFIGS()['dt.args.dsnodash'], 'yyyyMMdd')` |
-
-注意：变量名保持原样（`ds_nodash` 不会变成 `ds`），只是外层包 DATE_FORMAT。
-
-### 带运算的变量
-
-最终输出统一使用 `sub_days` 函数（有一个后处理步骤会将所有 `DATE_SUB`/`DATE_ADD` 转为 `sub_days`）：
-
-| 输入 | 最终输出 |
-|------|----------|
-| `${ds - 1}` | `DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')` |
-| `${ds + 7}` | `DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], -7), 'yyyy-MM-dd')` |
-| `${ds_nodash - 1}` | `DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds_nodash'], 1), 'yyyyMMdd')::STRING` |
-
-规则：
-- `-` 运算 → `sub_days(..., N)`（N 为正数）
-- `+` 运算 → `sub_days(..., -N)`（N 取反为负数）
-- 外层包 `DATE_FORMAT`，格式根据变量名决定：
-  - 含 `nodash` → `'yyyyMMdd'`
-  - 不含 `nodash` → `'yyyy-MM-dd'`
-- 含 `nodash` 的变量带运算时，追加 `::STRING` 类型转换
-
-注意：这是最终输出形式。中间步骤可能先生成 `DATE_SUB`/`DATE_ADD`，但最终会被后处理统一转为 `sub_days`。
-
-### macros.ds_add 函数
-
-| 输入 | 输出 |
-|------|------|
-| `${macros.ds_add(ds, -1)}` | `DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')` |
-| `${macros.ds_add(ds, 7)}` | `DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], -7), 'yyyy-MM-dd')` |
-
-注意：`macros.ds_add` 的第二个参数与 `sub_days` 的参数符号相反。`macros.ds_add(ds, -1)` 表示 ds 减 1 天，对应 `sub_days(ds, 1)`（正数=减天数）；`macros.ds_add(ds, 7)` 表示 ds 加 7 天，对应 `sub_days(ds, -7)`（负数=加天数）。
-
-## 引号上下文规则
-
-占位符的处理方式取决于它所在的引号上下文：
-
-### 情况1：占位符在单引号内（纯占位符）
-
-```sql
--- 输入
-WHERE dt = '${ds}'
--- 输出（去除外层引号，直接替换）
-WHERE dt = SESSION_CONFIGS()['dt.args.ds']
-```
-
-### 情况2：占位符在单引号内（混合内容）
-
-当引号内同时包含占位符和字面文本时，使用 CONCAT：
-
-```sql
--- 输入
-WHERE dt = '${ds_nodash}_done'
--- 输出
-WHERE dt = CONCAT(DATE_FORMAT(SESSION_CONFIGS()['dt.args.ds_nodash'], 'yyyyMMdd'), '_done')
-```
-
-```sql
--- 输入
-WHERE path = '/data/${region}/output'
--- 输出
-WHERE path = CONCAT('/data/', SESSION_CONFIGS()['dt.args.region'], '/output')
-```
-
-### 情况3：占位符不在引号内
-
-```sql
--- 输入
-WHERE dt = ${ds}
--- 输出
-WHERE dt = SESSION_CONFIGS()['dt.args.ds']
-```
-
-### 情况4：占位符在单引号内，且是日期运算
-
-```sql
--- 输入
-WHERE dt = '${ds - 1}'
--- 输出（去除外层引号，添加 ::STRING 类型转换）
-WHERE dt = DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')::STRING
-```
-
-### 引号内的引号选择
-
-当替换后的表达式仍然处于单引号字符串内部时（如 CONCAT 场景），SESSION_CONFIGS 的键名使用双引号以避免引号冲突：
-```sql
--- 在 CONCAT 等单引号上下文中
-CONCAT('prefix_', SESSION_CONFIGS()["dt.args.ds"])
-
--- 独立表达式（外层引号已去除）
-SESSION_CONFIGS()['dt.args.ds']
-```
-
-## 静态分区中的占位符
-
-静态分区值中的占位符替换后，值会被注入到 SELECT 子句：
-
-```sql
--- 输入
-INSERT OVERWRITE TABLE t PARTITION(dt='${ds}', region='${region}')
-SELECT col1 FROM source;
-
--- 转换后
-SELECT col1,
-    SESSION_CONFIGS()['dt.args.ds'] AS dt,
-    SESSION_CONFIGS()['dt.args.region'] AS region
-FROM source;
-```
-
-## 不可识别的表达式
-
-对于无法解析的复杂表达式（如 Airflow Jinja 模板），进行清洗：
-1. 将 Python strftime 格式符转为 SQL 风格：`%Y`→`yyyy`, `%m`→`MM`, `%d`→`dd`, `%H`→`HH`
-2. 非字母数字下划线字符替换为 `_`
-3. 合并连续下划线，去除首尾下划线
-4. 用清洗后的字符串作为 SESSION_CONFIGS 的键名
-
-```sql
--- 输入
-${execution_date.strftime("%H00")}
--- 清洗后键名: execution_date_strftime_HH00
--- 输出
-SESSION_CONFIGS()['dt.args.execution_date_strftime_HH00']
-```
-
-## 完整示例
-
-### 输入
-```sql
-INSERT OVERWRITE TABLE kscdm.dim_table
-PARTITION(p_date='{{ ds_nodash }}_done', product='done', dt='{{ ds }}')
-SELECT id, name
-FROM source_table
-WHERE dt = '{{ ds }}'
-  AND prev_dt = '{{ ds - 1 }}'
-  AND region = '{{ region }}';
-```
-
-### 输出（占位符替换后）
-```sql
-SELECT id, name,
-    CONCAT(DATE_FORMAT(SESSION_CONFIGS()['dt.args.ds_nodash'], 'yyyyMMdd'), '_done') AS p_date,
-    'done' AS product,
-    SESSION_CONFIGS()['dt.args.ds'] AS dt
-FROM source_table
-WHERE dt = SESSION_CONFIGS()['dt.args.ds']
-  AND prev_dt = DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')::STRING
-  AND region = SESSION_CONFIGS()['dt.args.region'];
-```

-# Dynamic Table Refresh 与调度文件生成规则
-
-你是一个 SQL 转换专家。在生成 Dynamic Table DDL 之后，还需要生成配套的 refresh 语句、回填语句和调度配置文件。
-
-## Refresh 语句生成
-
-### 变量提取
-
-从转换后的 DDL 中提取所有 `SESSION_CONFIGS()['dt.args.XXX']` 中的变量名 XXX，去重后排序。
-
-注意：只提取 DDL 中实际出现的变量名。例如如果 DDL 中只有 `SESSION_CONFIGS()['dt.args.ds_nodash']`，则只生成 `ds_nodash` 一个变量的 SET 语句。
-
-### 三类 Refresh 文件
-
-对每个转换的表，生成三类文件：
-
-#### 1. 当前周期 refresh（`表名_refresh.sql`）
-
-```sql
-set dt.args.ds = ${ds};
-set dt.args.region = ${region};
-REFRESH DYNAMIC TABLE schema.table_name PARTITION(ds = '${ds}', region = '${region}');
-```
-
-规则：
-- 为每个提取到的变量生成一条 `set dt.args.变量名 = ${变量名};`
-- 变量按字母序排列
-- PARTITION 子句只包含静态分区列（从原始 INSERT OVERWRITE 的 PARTITION 子句中提取）
-- 分区值使用 `'${变量名}'` 格式
-
-#### 2. 上一周期 refresh（`表名_prev_refresh.sql`）
-
-```sql
-set dt.args.ds = ${prev_ds};
-set dt.args.region = ${prev_region};
-REFRESH DYNAMIC TABLE schema.table_name PARTITION(ds = '${prev_ds}', region = '${prev_region}');
-```
-
-规则：每个变量名加 `prev_` 前缀。
-
-#### 3. 回填语句（`表名_backfill.sql`）
-
-```sql
-set cz.optimizer.incremental.backfill.enabled = TRUE;
-
-INSERT OVERWRITE schema.table_name
-SELECT *
-FROM ext_schema.table_name
-WHERE ds = '${ds}' AND region = '${region}';
-```
-
-规则：
-- 固定的 backfill 开关 SET 语句
-- 从扩展表（ext_schema）SELECT * 到目标表
-- WHERE 条件使用静态分区列（从原始 INSERT OVERWRITE 的 PARTITION 子句中提取）
-
-### 无分区表
-
-如果表没有静态分区变量：
-- 只生成当前周期 refresh：`REFRESH DYNAMIC TABLE schema.table_name;`
-- 不生成 prev_refresh 和 backfill 文件
-
-### 扩展表名规则
-
-- 如果指定了 `ext_schema`：`ext_schema.table_name`
-
-## 完整示例
-
-### 输入（转换后的 DDL 含以下变量）
-
-DDL 中包含：`SESSION_CONFIGS()['dt.args.ds']` 和 `SESSION_CONFIGS()['dt.args.region']`
-原始 PARTITION：`PARTITION(dt='${ds}', region='${region}')`
-
-### 输出
-
-**refresh.sql:**
-```sql
-set dt.args.ds = ${ds};
-set dt.args.region = ${region};
-REFRESH DYNAMIC TABLE kscdm.my_table PARTITION(dt = '${ds}', region = '${region}');
-```
-

-set dt.args.region = ${prev_region};
-REFRESH DYNAMIC TABLE kscdm.my_table PARTITION(dt = '${prev_ds}', region = '${prev_region}');
-```
-
-**backfill.sql:**
-```sql
-set cz.optimizer.incremental.backfill.enabled = TRUE;

-# Dynamic Table 自引用表转换规则
-
-你是一个 SQL 转换专家。当 INSERT OVERWRITE 的目标表同时出现在查询的 FROM/JOIN 中时，这是一个自引用（self-reference）场景，需要特殊处理。
-
-## 自引用检测
-
-### 判断条件
-
-1. 从 INSERT OVERWRITE 语句中提取目标表名（含 schema）
-2. 在 SELECT 查询的 FROM 和 JOIN 子句中搜索该表名
-3. 排除 PARTITION 子句中的表名引用（不算自引用）
-4. 如果在 FROM/JOIN 中找到目标表名 → 判定为自引用
-
-### 示例
-
-```sql
--- 目标表: kscdm.daily_sales
-INSERT OVERWRITE TABLE kscdm.daily_sales PARTITION(ds='${ds}')
-SELECT current.id, current.amount
-FROM source_sales current
-LEFT JOIN kscdm.daily_sales prev ON current.id = prev.id  -- ← 自引用
-WHERE prev.ds = '${ds - 1}';
-```
-
-## 转换规则
-
-自引用表的转换与普通表基本相同，但有以下区别：
-
-### 1. 显式 Schema 声明
-
-自引用表必须在 CREATE DYNAMIC TABLE 中显式声明完整的列定义（含类型），因为 SQL 引擎需要这些信息来推理自依赖列的类型：
-
-```sql
-CREATE OR REPLACE DYNAMIC TABLE kscdm.daily_sales (
-    id BIGINT COMMENT '...',
-    amount DECIMAL(10,2) COMMENT '...',
-    ds STRING COMMENT '...'
-)
-PARTITIONED BY (ds)
-AS
-SELECT current.id, current.amount,
-    SESSION_CONFIGS()['dt.args.ds'] AS ds
-FROM source_sales current
-LEFT JOIN kscdm.daily_sales prev ON current.id = prev.id
-WHERE prev.ds = DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')::STRING;
-```
-
-### 2. 查询中保留自引用
-
-转换后的 AS 子句中，自引用表名保持不变，不做任何替换。SQL 引擎会自动处理自引用的版本管理。
-
-## 常见自引用场景
-
-### 日环比计算
-
-```sql
--- 输入
-INSERT OVERWRITE TABLE metrics PARTITION(ds='${ds}')
-SELECT t.id, t.value,
-    t.value - prev.value AS daily_change
-FROM source t
-LEFT JOIN metrics prev ON t.id = prev.id AND prev.ds = '${ds - 1}';
-
--- 输出
-CREATE OR REPLACE DYNAMIC TABLE metrics (
-    id BIGINT, value DECIMAL(10,2), daily_change DECIMAL(10,2), ds STRING
-)
-PARTITIONED BY (ds)
-AS
-SELECT t.id, t.value,
-    t.value - prev.value AS daily_change,
-    SESSION_CONFIGS()['dt.args.ds'] AS ds
-FROM source t
-LEFT JOIN metrics prev ON t.id = prev.id
-    AND prev.ds = DATE_FORMAT(sub_days(SESSION_CONFIGS()['dt.args.ds'], 1), 'yyyy-MM-dd')::STRING;

-# SQL → Dynamic Table 完整转换工作流
-
-当用户给你一组 CREATE TABLE DDL 和 INSERT OVERWRITE SQL，要求转换为 Dynamic Table 时，按以下步骤顺序执行。
-
-每一步的详细规则在对应的 skill 文件中，你需要同时引用它们。
-
-## 工作流步骤
-
-### Step 1: 预处理输入
-
-从 INSERT OVERWRITE 文件中移除：
-- 所有 `ALTER TABLE` 语句
-- `ANALYZE TABLE` 语句
-- SQL 注释（`--` 和 `/* */`）
-
-保留：CREATE TABLE、INSERT OVERWRITE、WITH、SET、CREATE TEMPORARY FUNCTION。
-
-### Step 2: 占位符替换
-
-按 `sql2dt-placeholder-rules.md` 中的规则：
-1. 统一占位符格式（`{{ }}` → `${ }`）
-2. 替换所有占位符为 `SESSION_CONFIGS()` 调用
-3. 处理 nodash 变量、日期运算、macros 函数
-4. 根据引号上下文决定处理方式（去引号 / CONCAT / 直接替换）
-
-### Step 3: 自引用检测
-
-按 `sql2dt-self-reference-rules.md` 中的规则：
-1. 检查 INSERT OVERWRITE 目标表是否出现在 FROM/JOIN 中
-2. 如果是自引用表，标记并在后续步骤中添加注释、使用显式 schema
-
-### Step 4: 核心转换
-
-按 `sql2dt-conversion-rules.md` 中的规则：
-1. 解析 CREATE TABLE DDL（提取列、分区、属性等）
-2. 解析 INSERT OVERWRITE（提取查询、分区类型）
-3. 组装 `CREATE OR REPLACE DYNAMIC TABLE ... AS SELECT ...`
-4. 注入静态分区值到 SELECT（智能引号处理）
-5. 合并表属性模板（默认 `data_lifecycle=15`）
-6. 处理 UNION ALL（每个分支独立注入）
-7. 日期函数后处理：将所有 `DATE_SUB/DATE_ADD` 统一转为 `sub_days`
-
-### Step 5: 列校验
-
-按 `sql2dt-column-validation-rules.md` 中的规则：
-1. 计算 schema 列数和 SELECT 列数
-2. 验证两者相等
-3. 检查重复别名和缺失分区列
-4. UNION ALL 分支列数一致性检查
-
-### Step 6: 生成配套文件
-
-按 `sql2dt-refresh-rules.md` 中的规则：
-1. 从 DDL 中提取所有 SESSION_CONFIGS 变量
-2. 生成当前周期 refresh 语句
-3. 生成上一周期 prev_refresh 语句
-4. 生成回填 backfill 语句
-
-## 输出清单
-
-对每个表，最终输出：
-
-| 文件 | 内容 | 条件 |
-|------|------|------|
-| `表名.sql` | Dynamic Table DDL | 始终生成 |
-| `表名_refresh.sql` | 当前周期 REFRESH 语句 | 始终生成 |
-| `表名_prev_refresh.sql` | 上一周期 REFRESH 语句 | 仅有分区变量时 |
-| `表名_backfill.sql` | 回填语句 | 仅有分区变量时 |
-
-## 快速判断路径
-
-```
-输入 DDL + INSERT OVERWRITE
-  │
-  ├─ 有占位符？ → Step 2 占位符替换
-  │
-  ├─ 自引用？ → Step 3 特殊处理
-  │
-  ├─ 有静态分区？ → Step 4 注入分区值到 SELECT
-  │
-  ├─ 有 UNION ALL？ → Step 4 每个分支独立注入
-  │
-  └─ 生成 DDL → Step 5 校验 → Step 6 生成配套文件

-name: table-optimization
-description: |
-  Clickzetta 表优化与治理工具。使用场景：分析表的小文件问题、检查 Compaction 配置、识别废弃表、优化表生命周期，并给出优化建议。触发词：小文件、compaction 配置检查、废弃表分析、文件分布诊断、分区优化建议、data_lifecycle、表治理建议。禁止触发场景：用户明确要求“直接执行 SQL”（例如 `OPTIMIZE schema.table`、`OPTIMIZE sql帮我手动执行一下`）时，不调用本 skill，应改用 SQL 执行工具。重要：该优化必须通过 scripts/table_optimizer.py 脚本来生成辅助分析的代码。
----
-
-# Table Optimization Skill
-
-## ⚠️ 严格约束（必须遵守）
-
-**禁止自己编写或推理 SQL**。所有 SQL 必须通过脚本生成：
-调用 `execute_skill_script` 执行（仅允许 scripts/* 或 bin/*）。
-```bash
-# 运行脚本生成 SQL
-python scripts/table_optimizer.py <action> --table <table_name>
-```
-
-脚本输出 JSON，从中获取 `diagnostic_sql` 或 `optimization_sql` 字段执行。
-
-❌ 错误：`LH_execute_query(sql="SHOW PARTITIONS xxx")`  
-✅ 正确：先运行脚本，再执行脚本输出的 SQL
-
-**禁止误用本 skill 执行用户给定 SQL**：
-- 用户请求是“帮我执行 `OPTIMIZE schema.table` / 直接执行某条 SQL”时，本 skill 不应被触发
-- 该请求应路由到 SQL 执行工具，而不是表治理诊断流程
-
----
-
-## 可用 scripts 参数
-
-| 脚本参数                                       | 用途 |
-|--------------------------------------------|------|
-| `check_abandoned --table <name> --days 30` | 检查废弃表 |
-| `check_write_history --table <name>`       | 检查写入历史 |
-| `get_table_properties --table <name>`      | 获取表属性（含 Compaction 配置） |
-| `check_files --table <name>`               | 检查非分区表文件数量 |
-| `check_partitions --table <name>`          | 检查分区表文件分布 |
-| `optimize --table <name> --type <type>`    | 生成优化 SQL |
-
----
-
-## Compaction 优化流程
-
-### Step 1: 获取表属性
-
-```bash
-python scripts/table_optimizer.py get_table_properties --table schema.table_name
-```
-
-从输出判断：
-- `# Partition Information` 存在 → 分区表
-- `properties` 字段 → 现有 Compaction 配置
-- `statistics` 字段 → 表大小（byte）
-
-### Step 2: 根据表类型诊断
-
-**非分区表**：
-```bash
-python scripts/table_optimizer.py check_files --table schema.table_name
-```
-
-**分区表**：
-```bash
-python scripts/table_optimizer.py check_partitions --table schema.table_name
-```
-
-**小文件问题判断标准**（参考值，非硬性阈值）：
-
-| 指标 | 参考值 | 说明 |
-|-----|-------|------|
-| 平均文件大小 | ~768MB | 低于此值可能存在小文件问题 |
-| 文件数量 | ~10 个 | 高于此值且平均文件较小时需关注 |
-
-**判断逻辑**：
-- ✅ 明显需要优化：平均文件大小 << 768MB **且** 文件数量 >> 10
-- ⚠️ 边界情况：接近参考值时（如 700MB、12 个文件），可灵活判断
-- ❌ 无需优化：平均文件大小接近或超过 768MB，或文件数量较少
-
-**示例**：
-- 表大小 5GB，文件数 100 → 平均 50MB → ✅ 明显需要优化
-- 表大小 8GB，文件数 12 → 平均 ~670MB → ⚠️ 边界情况，可观察
-- 表大小 1GB，文件数 5 → 平均 200MB，文件数少 → ❌ 不需优化
-- 表大小 100GB，文件数 50 → 平均 2GB → ❌ 平均文件大小足够
-
-### Step 3: 生成优化 SQL（如需优化）
-
-⚠️ **参数配置原则**：
-- 先从 Step 1 的 `properties` 字段获取当前配置值
-- 如果**没有配置**：使用默认值（`min-interval=1800`，`partition-window=3600`）
-- 如果**已有配置但需要调小**：在当前值基础上调整（如当前 3600 → 调整为 1800）
-- **不要覆盖用户已有的合理配置**
-
-**非分区表**（DML 模式）：
-```bash
-# 默认值（无现有配置时）
-python scripts/table_optimizer.py optimize --table schema.table_name --type compaction_daily --min-interval 1800
-
-# 如果当前 cz.compaction.min.interval=3600，需要调小
-python scripts/table_optimizer.py optimize --table schema.table_name --type compaction_daily --min-interval 1800
-```
-
-**分区表**（DML + Background 模式）：
-```bash
-# 默认值（无现有配置时）
-python scripts/table_optimizer.py optimize --table schema.table_name --type compaction_hourly --min-interval 1800 --partition-window 3600
-
-# 根据现有配置调整示例：
-# - 当前 min.interval=3600 → 调整为 1800
-# - 当前 partition.window=7200 → 调整为 3600
-python scripts/table_optimizer.py optimize --table schema.table_name --type compaction_hourly --min-interval 1800 --partition-window 3600
-```
-
-**参数调整决策表**：
-
-| 当前配置 | 小文件问题 | 建议操作 |
-|---------|-----------|---------|
-| 无配置 | 有 | 使用默认值：`min-interval=1800`, `partition-window=3600` |
-| `min.interval=3600` | 有 | 调小为 `1800` |
-| `min.interval=1800` | 有 | 保持不变，建议手动触发 OPTIMIZE |
-| `partition.window=7200` | 有 | 调小为 `3600` |
-| `partition.window=3600` | 有 | 保持不变，建议手动触发 OPTIMIZE |
-| 配置合理 | 无 | 无需优化 |
-
----
-
-## Compaction 策略说明
-
-| 模式 | 配置值 | 含义 |
-|-----|-------|------|
-| DML | `cz.compaction.strategy=dml` | DML 触发，间隔由 `min.interval` 控制 |
-| Background | `cz.compaction.strategy=background` | 后台自动，忽略窗口由 `ignore.latest.partition.window` 控制 |
-| DML+Background | `cz.compaction.strategy=dml\|background` | 同时启用 |
-
-**默认**：未配置时使用 Background 模式。
-
----
-
-## 注意事项
-
-1. **所有 SQL 必须由脚本生成** - 禁止自己编写
-2. **ALTER TABLE 需用户确认** - 不要自动执行
-3. **手动触发 Compaction 只能建议** - 命令是 `OPTIMIZE schema.table_name`，不要自动执行
-4. **表名格式** - 必须使用 `schema.table` 两段式命名
-5. **小文件判断标准** - 参考值（非硬性阈值）：平均文件大小 ~768MB，文件数量 ~10，接近标准也可接受
-6. **参数配置智能化** - 必须先获取当前配置，根据现有值决定新配置：
-   - 无配置 → 使用默认值
-   - 有配置但需调整 → 在当前值基础上调小
-   - 配置已经很小 → 保持不变，建议手动 OPTIMIZE

----
-
-## Step 1: 收集错误信息
-
-### 1.1 基础信息收集（必须）
-
-```
-1. 调用 get_task_detail(task_id) 获取任务基本信息（非必需步骤）
-   → 确定任务类型：SQL / Shell / Python / 多表实时同步 / 离线同步 
-
-2. 调用 get_task_instance_detail(instance_id) 获取实例详情
-   → 获取实例状态、开始时间、结束时间、错误码
-
-3. 调用 get_execution_log(instance_id) 获取执行日志
-   → 获取详细错误信息和堆栈
-```
-
-### 1.2 扩展信息收集（按需）
-
-| 场景 | 需要调用的工具 |
-|------|---------------|
-| 疑似依赖问题 | `get_task_run_dependencies(instance_id)` |
-| 需要分析历史 | `list_task_run(task_id)` |
-| 检查配置问题 | `get_task_configuration_detail(task_id)` |
-| 分析运行趋势 | `get_task_run_stats(task_id)` |
-
----
-
-## Step 2: 错误分类

-
-### 2.1 数据集成错误 (INTEGRATION)
-
-**识别特征**：任务类型为数据同步/数据集成
-
-| 子类型 | 特征关键字 |
-|--------|-----------|

-
-如果无法匹配以上任何类别，归类为 OTHER，需要进一步分析。
-
----
-
-## Step 3: 执行对应诊断策略
-
-### 3.1 数据集成错误诊断
-
-```
-1. 调用 get_task_detail 确定集成类型（离线同步 / 实时同步）
-2. 调用 get_execution_log 获取详细错误
-3. 根据子类型定位问题端：
-   - SOURCE: 检查源端连接、权限、表是否存在
-   - TRANSFER: 检查网络状态、传输配置
-   - TARGET: 检查目标端权限、冲突处理策略
-   - dataType：字段类型错误，可直接给出结论：直接提示字段错误查看目标表的字段是否正确。
-4. 调用 get_task_configuration_detail 检查配置
-5. 生成针对性解决方案
-```
-
-### 3.2 SQL 执行错误诊断
-
-```
-1. 调用 get_execution_log 获取完整错误日志
-2. 判断错误子类型：
-   - SYNTAX/SEMANTIC: 
-     * 分析 SQL 语句，定位具体错误位置
-     * 参考 reference/error_patterns.yaml 中的模式
-   - RESOURCE: 
-     * 如果包含 "stage" 关键字，需要分析 job history
-     * 调用 get_task_run_stats 分析资源使用趋势
-   - PERMISSION: 
-     * 检查用户权限配置
-3. 生成 SQL 修改建议或资源优化建议
-```
-
-### 3.3 调度错误诊断
-
-```
-1. 根据子类型执行诊断：
-   - DEPENDENCY: 
-     * 调用 get_task_run_dependencies 获取依赖关系
-     * 逐个检查上游任务状态
-     * 找到失败的根因任务
-   - CONFIG:
-     * 调用 get_task_configuration_detail 检查任务配置
-     * 检查超时设置、cron 表达式
-   - RESOURCE:
-     * 检查 VC 状态和队列排队情况
-2. 调用 list_task_run 查看历史，判断是否偶发
-3. 生成解决方案
-```
-
-### 3.4 数据质量错误诊断
-
-```
-1. 调用 get_task_detail 获取 DQC 规则配置
-2. 调用 get_execution_log 获取校验结果详情
-3. 分析失败原因：
-   - 规则配置是否合理
-   - 数据本身是否有问题
-4. 生成修复建议
-```
-
----
-
-## Step 4: 生成解决方案
-
-根据诊断结果，从以下维度生成解决方案：
-
-### 解决方案结构
-
-```
-标题: [简明描述问题和解决方向]
-根因: [一句话说明根本原因]
-步骤:
-  1. [具体操作步骤1]
-  2. [具体操作步骤2]
-  ...
-预期效果: [执行后的预期结果]
-注意事项: [可选，需要特别注意的点]
-```
-
-### 常见解决方案
-
-参考 `reference/solutions.yaml` 获取预定义的解决方案模板。
-
----
-
-## Step 5: 输出诊断报告
-
-### 报告格式
-
-```markdown
-## 诊断报告
-
-**任务信息**
-- 任务ID: {task_id}
-- 实例ID: {instance_id}
-- 任务类型: {task_type}
-
-**错误分类**
-- 类别: {category}

-## 案例 1: 作业超时 - SDK killed
-
-### 错误现象
-
-```
-Clickzetta sql job: xxx
-Timeout after 300.0seconds, killed by sdk
-```
-
-**关键字**: `timeout`, `killed by sdk`, `300.0seconds`
-
-**分类**: SQL > 资源错误 (RESOURCE)
-
----
-
-### 诊断思路
-
-```
-Step 1: 为什么超时？
-    │
-    ├─→ 检查资源是否够用（整体以及 VC 都看下）
-    │
-    ├─ 资源不够用 → 先加资源，然后到 Step 2
-    │
-    └─ 资源够用 → 到 Step 2
-
-Step 2: 这个作业应该跑多久？5分钟是个合理超时时间还是不是？
-    │
-    ├─→ 调用 get_task_run_stats 查看历史运行时间平均值
-    │
-    ├─ 5分钟不合理（SQL本身就慢）→ 看 SQL 为什么跑得慢，优化 SQL
-    │
-    └─ 5分钟合理 → 到 Step 3
-
-Step 3: 5分钟超时哪儿来的？
-    │
-    ├─→ 执行 desc vcluster 看看 VC 上配了没
-    │
-    └─→ 也可能来自很老的 Python connector，用文档里的方法把超时时间加大
-```
-
----
-
-### 解决方案
-
-**根因**: Python SDK 默认超时时间（300秒）不足以完成作业
-
-**步骤**:
-1. 检查 VC 资源配置：执行 `desc vcluster` 查看超时配置
-2. 检查 Python connector 版本，确认是否使用了旧版本
-3. 在代码中设置作业运行超时时间
-
-**代码示例**:
-
-```python
-# 设置作业运行超时时间为 30 秒（或更长，根据实际需要调整）
-my_param = {
-    'hints': {
-        'sdk.job.timeout': 30
-    }
-}
-
-cursor.execute('YOUR_SQL_QUERY', parameters=my_param)
-```
-
-**参考文档**: https://yunqi.tech/documents/python_reference/connector
-
----
-
-### 关键点
-
-- 超时可能来自 VC 配置或 SDK 配置
-- 先排查资源问题，再看超时配置
-- 历史运行时间是判断超时是否合理的重要依据
-- 老版本 Python connector 可能有默认超时限制

- * Python → TS mapping:

- *   enhanced_lakehouse.py:50-180  EnhancedLakehouseClient              → LakehouseClient class

- *   enhanced_lakehouse.py:83-88   connect                              → connect()
- *   enhanced_lakehouse.py:105-135 _connect_via_api                     → _connectViaApi()
- *   enhanced_lakehouse.py:137-146 close                                → close()
- *   enhanced_lakehouse.py:148-153 run_sql                              → runSql()

- *
- * Divergences from Python:
- *   - Python uses clickzetta.connect() (DB-API cursor); TS uses SqlSession.execute()
- *   - Python returns JSON string from run_sql; TS returns rows array directly
- *   - runSqlWithSchema() is a TS addition (no Python equivalent) for callers
- *     that need column metadata alongside rows
- *   - Python has gRPC mode; TS only implements connect-API mode (no gRPC client)

-
-## 输入
-1. Semantic View 名称: {semantic_view_name}
-2. 用户描述: {user_description}
-
-## 步骤
-
-### 1. 获取 Semantic View 定义
-使用 \`desc_semantic_view\` 获取当前定义，查看：
-- 已有的 TABLES（逻辑表）
-- 已有的 DIMENSIONS（已添加的维度）
-- 可用的表字段
-
-### 2. 分析用户需求
-从用户描述中提取：
-- 需要添加的维度类型（日期、地区、类别等）
-- 相关的业务实体（订单、客户、商品等）
-- 维度的用途
-
-### 3. 选择维度
-从 TABLES 中选择合适的字段作为维度：
-- 字段必须来自已定义的逻辑表
-- 避免重复（检查已有 DIMENSIONS）
-- 考虑字段的业务含义
-
-### 4. 输出 JSON
-返回要添加的维度列表：
-
-\`\`\`json

-  "dimensions": [
-    {
-      "logical_table": "逻辑表名",
-      "dimension_name": "字段名",

-
-            Create and optionally trigger DQC (Data Quality Check) rule execution.
-
-            **Core Features:**
-
-            1. **Rule Creation**
-               - Create manual (REST), scheduled (PLAN), or task-based (SCHEDULE_TASK) DQC rules
-               - Support built-in metrics (table_count, avg, count, etc.) and custom SQL
-               - Auto-generate checker_info from operator and expected_value
-
-            2. **Flexible Trigger Options**
-               - REST: Manual trigger rules
-               - PLAN: Scheduled rules with cron expressions
-               - SCHEDULE_TASK: Task-based rules with blocking levels
-
-            3. **Auto-Trigger Capability**
-               - Set auto_trigger=true to execute rule immediately after creation
-               - Only works for REST type rules
-               - Returns both rule_id and task_id
-
-            **Built-in Metrics:**
-            - table_count: Total rows in table (no column needed)
-            - count: Non-null count in column
-            - null_count: Null count in column
-            - count_distinct: Unique values in column
-            - count_repetition: Duplicate values in column
-            - avg, max, min, sum: Numeric aggregations (require column)
-
-            **Operators:**
-            - GREATER_THAN, LESS_THAN, EQUAL, NOT_EQUAL, GREATER_EQUAL, LESS_EQUAL
-
-            **Example Usage:**
-            \`\`\`

- * ArgumentNormalizer — port of cz-mcp-server/cz_mcp/transport/argument_normalizer.py
- *
- * Python → TS mapping:
- *   argument_normalizer.py:20-35   ArgumentNormalizationError class
- *   argument_normalizer.py:37-529  ArgumentNormalizer class
- *   argument_normalizer.py:48-70   constructor (__init__)

- *   argument_normalizer.py:102-112 _apply_defaults()
- *   argument_normalizer.py:114-124 _validate_required_fields()
- *   argument_normalizer.py:126-179 _convert_types()
- *   argument_normalizer.py:181-233 convert_value() [static]
- *   argument_normalizer.py:234-248 _types_match() [static]
- *   argument_normalizer.py:250-265 _to_int() [static]
- *   argument_normalizer.py:267-277 _to_number() [static]

- *   argument_normalizer.py:457-497 _build_type_conversion_error()
- *   argument_normalizer.py:499-528 _build_enum_error()
- *   argument_normalizer.py:531-553 create_normalizer_for_tool()
- *
- * Divergence from Python:
- *   - Python uses inspect.signature to extract handler parameter types at runtime.
- *     TS cannot reflect function signatures at runtime, so type conversion is driven
- *     entirely by input_schema's `type` field (same data, different source).
- *   - handler_params is always treated as non-empty (schema-driven), so the
- *     `if not self.handler_params: return arguments` guard in _convert_types is
- *     replaced by checking whether properties exist in the schema.

- *   - Python uses jsonpath_ng for JSONPath evaluation.

Subject: [PATCH 162/521] feat(setup): auto-fetch clickzetta API key on
 password login

After a successful username/password setup flow, calls
findOrCreateApiKey to populate [llm.clickzetta] in profiles.toml.
Failure is silently ignored and does not block setup.

Also fix autoupdate default from "notify" to true, add
profiles-llm-persist tests, and update autoupdate JSDoc.

+# W3C Traceparent Propagation Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Propagate W3C `traceparent` across ClickZetta LLM requests, ClickZetta SDK HTTP requests, and parent-to-child agent runtime handoff.
+
+**Architecture:** Add a small shared trace-context utility that can parse, validate, derive, and serialize `traceparent` values without depending on a fully-enabled OTEL runtime. Reuse it from `opencode` provider fetch wrapping, `@clickzetta/sdk` request builders, and `cz-cli` child-process delegation so all internal services receive consistent headers and parent/child relationships.
+
+**Tech Stack:** TypeScript, Bun tests, existing `@opentelemetry/api` runtime context where available, workspace packages `packages/opencode`, `packages/clickzetta-sdk`, `packages/cz-cli`.

Subject: [PATCH 163/521] fix(otel): flush telemetry on exit, inject
 credentials at build time

- Register beforeExit/SIGTERM/SIGINT hooks in OtelPlugin so BatchLogRecordProcessor
  flushes before process exits (mirrors @devtheops/opencode-plugin-otel behavior)
- Add .exitProcess(false) to yargs so trackCommand fetch completes before exit
- Move OTel endpoint/headers from hardcoded source to build-time define injection
  (CI injects via GitHub Secrets; local dev builds no-op without credentials)
- Add OPENCODE_DISABLE_TRACES category control in handlers (tool,llm,prompt)
- Redact sensitive CLI flag values in telemetry (password, token, pat, etc.)
- Harden profiles.toml writes: chmod 0600 after atomic rename
- setup: reuse isSensitiveKey, retry password login with instance on failure

Subject: [PATCH 164/521] fix(otel): fix opencode telemetry not reporting

Three root causes fixed:

1. OTel SDK packages used dynamic import() in setup.ts, which under Bun's
   browser-condition bundle produces separate module instances from the static
   imports in handlers.ts. setGlobalLoggerProvider() and logs.getLogger() then
   operated on different registries. Fixed by converting all OTel SDK imports
   to static imports and passing the logger instance directly to handlers via
   initHandlers(), bypassing the global registry entirely.

2. handlers.ts was listening for v2.prompt / v2.step.* / v2.tool.* event names
   copied from the upstream opencode-plugin-otel, but this fork's opencode
   emits session.created / session.status / session.idle instead. Rewrote
   handlers to map the actual event schema.

3. index.ts finally block called process.exit() directly, bypassing beforeExit.
   Added flushOtel() call before process.exit() to ensure BatchLogRecordProcessor
   flushes before the process terminates.

Subject: [PATCH 174/521] feat(otel): restore LLM/tool telemetry, TUI setup
 upgrade, telemetry pipeline fix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Telemetry pipeline:
- Fix root cause: compiled binary called runCli() directly, bypassing trackCommand().
  Add runCliWithTracking() wrapping runCli() with arg parsing + telemetry emission.
  Extract parseTrackingArgs() as shared utility. Simplify main.ts to use it.
- Normalize cz-cli command log attributes to cz_cli.command.* namespace.
- Unify username resource attribute across cz-cli and cz-agent paths.
- Change service.name from "opencode" to "cz-agent" for agent runtime logs.

OTel GenAI coverage:
- Add v2.step.started/ended and v2.tool.called/v2.tool.ended bus events in session.ts.
- Publish from processor.ts at LLM step and tool call lifecycle points.
  Fix stepId correlation: generate once in start-step, reuse in finish-step.
- Restore chat/{model} and execute_tool/{name} spans in handlers.ts per GenAI spec.
- Restore metrics aligned to GenAI spec (gen_ai.client.token.usage, operation.duration).
- Add session duration tracking (session.created → session.deleted).
- Unify log body format to match event names (e.g. "session.created", "llm.step.finished").
- Remove tool arguments/results from spans (contradicts telemetry consent language).
- Unify duration metric units to seconds.

Setup TUI:
- Replace readline prompts with @clack/prompts (arrow-key select, password masking, cancel).
- Add "New user / Already have account" question at start of TTY setup flow.
- New user path opens register URL and pastes credential (same flow as login).
- Custom URL: auto-append /login path and ?ref=cz-cli.
- JDBC parser: relax hostParts.length < 4 to < 2 for short service hostnames.
- applyCredentialToProfiles: only write username if credential contains it.
- profiles.toml writes: atomic rename + chmod 0600.

Tests:
- telemetry.test.ts: trackCommand attribute format verification.
- otel-handlers.test.ts: 14 cases covering all event types, failure paths, robustness.

Subject: [PATCH 177/521] feat(telemetry): replace username with enduser.id in
 OTel resource attributes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add patchProfileUserId() to profile-store: writes user_id from login token
  into the active profile. No-op if user_id already present — triggers at most
  once per profile lifetime.
- Call patchProfileUserId() in getExecContext() after successful token fetch,
  covering all Lakehouse commands (sql, table, schema, workspace, status).
- setup.ts: write user_id when creating profiles via credential or
  username/password login flows.
- telemetry.ts + plugin/index.ts: read user_id from profile and emit as
  enduser.id resource attribute instead of username (username is not unique
  globally; numeric userId is).

Subject: [PATCH 178/521] feat(telemetry): add enduser.id to all setup paths
 and OTel resource attributes

- All setup paths (credential, JDBC, username/password TTY/non-TTY) now
  fetch userId via getToken and pass it to trackSetup as enduser.id
- patchProfileUserId: no-op if user_id already present in profile
- getExecContext: auto-patches user_id on first Lakehouse command for
  existing users who set up before this change
- Remove username from OTel resource attributes; use enduser.id (numeric,
  unique per tenant) instead

Subject: [PATCH 179/521] fix(tui): default to keep-selection mode and patch
 opentui for drag-less terminals
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Set CLICKZETTA_EXPERIMENTAL_DISABLE_COPY_ON_SELECT default to true on
  all platforms so mouse selection stays visible after release; user
  presses Ctrl+C to copy instead of auto-copy-on-mouseup
- Add bun patch for @opentui/core@0.1.99: call updateSelection on mouseUp
  so selection spans mouseDown→mouseUp even when drag events are missing
  (terminal multiplexers, cmux, etc.) — backport of opentui PR#935

Subject: [PATCH 180/521] fix(update): strip bun virtual argv entry before
 re-exec after auto-update

In a compiled bun binary, process.argv is ["bun", "/$bunfs/root/<name>",
...userArgs]. The /$bunfs/ virtual path at argv[1] was being passed to the
re-exec'd process, causing yargs to reject it as an unknown argument:
  ERROR: Unknown argument: /$bunfs/root/src/index.js

Fix: detect binary mode via execPath !== argv[0] and slice(2) to skip both
the "bun" sentinel and the virtual path. In dev mode (execPath === argv[0])
slice(1) preserves the script path as before.

Extracted restartArgs() as a pure exported function and added unit tests
covering binary mode (mac/linux/windows) and dev mode.

Subject: [PATCH 182/521] fix(npm): refactor platform binary resolution with
 registry fallback, fix continue hint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Extract platform binary logic into platform.js with ensureInstalledBinary/resolveInstalledBinary
- postinstall.js: download from npm registry if optional platform package is absent
- run.js: use resolveInstalledBinary for consistent binary lookup
- Fix TUI session exit continue hint: cz-cli -s → cz-cli agent -s
- Switch index.ts and temporary.ts from hideBin to restartArgs for correct argv handling after auto-update re-exec

Subject: [PATCH 184/521] feat(otel): record conversation content on trace
 spans per GenAI semconv

Add gen_ai.input.messages, gen_ai.output.messages (including tool_call
decisions), gen_ai.tool.call.arguments, and gen_ai.tool.call.result to
OTEL spans so full AI interaction flows can be reconstructed from traces.

Content recording is gated by the telemetry=true flag in profiles.toml;
span structure and metadata are always recorded when the OTEL endpoint
is configured.

Subject: [PATCH 185/521] fix(npm): force platform binary re-install on version
 mismatch

The npm multi-package architecture (launcher + optional platform binary)
could leave a stale binary after update because:
1. postinstall skipped re-download if any binary existed
2. run.js never checked if the binary version matched the launcher

Now:
- postinstall always force-downloads the platform binary (force: true)
- run.js checks binary --version against package.json version at startup
  and self-heals from npm registry if they diverge
- ensureInstalledBinary accepts a `force` flag to bypass existence check

Subject: [PATCH 187/521] fix(setup): don't strip /register path in custom
 registration URL

normalizeLoginInput strips /login suffix which is wrong for register URLs.
Use direct URL parsing that preserves the path.

Subject: [PATCH 188/521] fix(cli): suppress stack trace on usage errors, fix
 register URL path handling

- run-cli: don't re-throw when exitCode is already set (usage errors
  already output JSON and set exitCode, re-throwing causes uncaught
  exception stack trace in stderr)
- setup: fix custom register URL to append /register only when not
  already present, clean up label display

Subject: [PATCH 189/521] feat(provider): migrate ClickZetta models to gateway
 API with provider-prefixed IDs

- Add /gateway path prefix to ClickZetta base URL normalization
- Update model IDs to use provider/model format (e.g. qwen/qwen3.5-plus, deepseek/deepseek-v3.2)
- Add new models: deepseek-r1, qwen3.6-plus, qwen3.6-max-preview, qwen3.6-flash, qwen3-max, qwen3-coder-flash
- Fix multi-LLM config loading: non-default providers now get their baseURL loaded

Subject: [PATCH 191/521] fix(install): avoid nested npm pack failure in global
 postinstall

Strip inherited npm_* env vars before spawning `npm pack` in the
self-heal fallback, preventing parent/child npm lock conflicts during
`npm install -g`.

When force=true, prefer the already-installed optionalDependency package
if its version matches the target, skipping the npm pack call entirely.
This eliminates the most common failure path while still ensuring
version correctness.

 /**
  * `cz-cli update` — manually update cz-cli to the latest version.
  *
- * Detects installation method (npm global, bun global, or standalone binary)
- * and uses the appropriate update mechanism. Detects conflicts when both npm
- * and bun have the package installed globally.
+ * Detection flow:
+ * 1. Check if npm global has the package
+ * 2. Check if bun global has the package
+ * 3. If both → error, ask user to uninstall one
+ * 4. If one → use that package manager to update
+ * 5. If neither → clean up stale binaries via `which`, then install via npm

Subject: [PATCH 200/521] feat(tui): group /model dialog by LLM entry name
 instead of provider

When profiles.toml has [llm.*] entries, the model selection dialog now
groups models by entry name (e.g. "my-openai", "work-anthropic") rather
than by provider. Falls back to provider-based grouping when no entries
are configured.

Subject: [PATCH 201/521] fix(cli): add opencode path aliases to cz-cli
 tsconfig for typecheck

cz-cli imports opencode source via relative paths, so tsgo needs the
same path mappings to resolve @/ and @tui/ aliases.

Subject: [PATCH 209/521] fix(release): tolerate already-published packages and
 pin update version

npm-publish.sh: when a platform package already exists on npm (E403 from
a partial prior run), skip it instead of failing the entire publish job.
This prevents the main package from being orphaned when CI is re-run.

update command: install the specific version detected from GitHub Releases
instead of @latest, which may lag behind if the publish partially failed.

Subject: [PATCH 210/521] fix(cli): improve -o/--output deprecation errors and
 --format help clarity

- Replace usesLegacyOutputFlag with stripLegacyOutputFlag to correctly
  identify the target command even when -o appears before the command name
- Provide actionable ai_message listing valid --format choices per command
- Fix agent run --help showing merged choices from both layers by clearing
  inherited global format choices in the subcommand builder
- Update e2e tests to match new message format

 Key tools:
 - `--field <name>` — extract one value as raw text: `cz-cli sql "..." --field job_id` → `2026042818122957849079780`
-- `-o toon` — line-per-field output, works with `grep`/`head`
-- `-o json` — single-line JSON, parse in code only (do NOT pipe to grep/head)
+- `--format toon` — line-per-field output, works with `grep`/`head`
+- `--format json` — single-line JSON, parse in code only (do NOT pipe to grep/head)
 
 **Shortcut**: Use `cz-cli sql --sync "..." > /tmp/res.json` to force synchronous execution (waits for results inline). Prefer `--sync` for simple/fast queries.

-# cz-cli — ClickZetta Lakehouse Subagent
+# cz-cli Skill
 
-You have no direct Lakehouse access. Always delegate via cz-cli.
+> [!IMPORTANT]
+> **Fallback**: If `cz-cli` command not present, check for a bundled binary at `scripts/<platform>/cz-cli` (e.g. `scripts/macos-arm64/cz-cli`, `scripts/linux-x86_64/cz-cli`, `scripts/windows-x86_64/cz-cli.exe`). If found, use its absolute path directly. Otherwise run `pip3 install cz-cli -U` then use `cz-cli` from PATH.
 
-## Capabilities
+## AI Agent Behavior Rules
 
-### SQL & Data Operations
-- Execute any SQL against Lakehouse: SELECT, DDL (CREATE/ALTER/DROP TABLE, SCHEMA, VIEW), DML (INSERT, UPDATE, DELETE, MERGE INTO)
-- Run async jobs and fetch results
-- Preview table data and row counts
+> [!IMPORTANT]
+> Read these rules before invoking any command.
 
-### Table & Schema Management
-- List, describe, create, and drop tables and schemas
-- View table history, indexes, partitions, and statistics
-- Add or update column/table comments
-- Create Dynamic Tables for auto-incremental ETL (ODS→DWD→DWS pipelines)
-- Create Materialized Views for pre-computed aggregations
-- Create Table Streams to capture INSERT/UPDATE/DELETE changes for CDC UPSERT
+### Rule 0 — Initialize connection profile before first use
 
-### Studio Task Management
-- Create, configure, deploy, and delete Studio tasks (SQL, Shell, Python, integration, flow)
-- Save task content and cron schedule
-- Deploy, undeploy, and execute tasks ad-hoc
-- Monitor run instances: list, detail, wait, logs, stop, rerun, backfill
-- View run statistics and dependencies
+When any command returns error code `NO_PROFILE`, run `cz-cli setup --credential <base64>` if the credential string is available, or read `references/profile-setup.md` and follow the onboarding steps there. Always use the **AskUserQuestion tool** — never ask via plain text.
 
-### Data Sync Pipelines
-- Create single-table realtime CDC sync tasks (MySQL/PostgreSQL/SQL Server → Lakehouse, task_type=28)
-- Create multi-table or whole-database CDC sync tasks — mirror, merge, or sharded-table consolidation (task_type=281)
-- Create offline batch sync tasks with Cron scheduling — single-table (task_type=10) or multi-table (task_type=291)
-- Manage sync task lifecycle: start, stop, offline, backfill, add tables, re-sync individual tables
+### Rule 1 — Clarify intent before any state-changing operation
 
-### Data Ingestion Pipelines
-- Create continuous OSS/S3/COS ingest PIPE (LIST_PURGE scan mode or EVENT_NOTIFICATION mode)
-- Create continuous Kafka ingest PIPE using READ_KAFKA function
-- One-shot file import from URL, local path, or Volume (COPY INTO)
-- Manage PIPE lifecycle: pause, resume, adjust batch interval, view load history
+When a task involves an operation that changes system state (publishing a schedule, taking a task offline, triggering a run, deleting an object, etc.):
 
-### Data Recovery
-- Query data at a historical point in time (Time Travel: TIMESTAMP AS OF)
-- Roll back a table to a previous version (RESTORE TABLE)
-- Recover accidentally dropped tables, dynamic tables, or materialized views (UNDROP TABLE)
-- Inspect change history (DESC HISTORY) and deleted objects (SHOW TABLES HISTORY)
-- Configure retention: data_retention_days, data_lifecycle
+**Do NOT proceed without** explicitly understanding the user's intent on all three points:
+1. **Target**: Which task / table / run instance?
+2. **Purpose**: Why does this need to happen now?
+3. **Side-effect acknowledgment**: Does the user understand the impact (historical re-runs, schedule interruption, permanent deletion, etc.)?
 
-### Connection & Environment Management
-- Create, update, delete, and switch connection profiles (multi-cloud, multi-region)
-- Check connection status and switch workspace
-- List and test external data sources, browse catalogs and objects
-- Generate Python SDK / ZettaPark / SQLAlchemy / JDBC connection code from profile parameters
+Use the **AskUserQuestion tool** (not plain text) to confirm with the user, then wait for an explicit reply before executing.
 
-## Route to cz-cli
+Consult **Command Risk Reference** below to determine whether a command qualifies as state-changing.
 
-- Any mention of cz-cli, ClickZetta, or Lakehouse
-- SQL against Lakehouse (SELECT, DDL, DML)
-- Studio task development, scheduling, monitoring
-- Data pipelines (sync, import, CDC, streaming)
-- Profile and connection configuration
-- Performance analysis and optimization
 
-## Keep in host agent
+### Rule 2 — Route to companion skill BEFORE acting (MUST)
 
-- General programming unrelated to ClickZetta
-- Local file operations, git
-- Non-ClickZetta databases (PostgreSQL, MySQL standalone)
+> [!IMPORTANT]
+> Check this routing table **before** executing any command or writing any code.
+> If the user intent matches a trigger below, **MUST** invoke the listed skill immediately and stop processing in cz-cli.
 
-## Execution strategy
+The following companion skills are bundled with `cz-cli`:
 
-**MANDATORY: Follow this order every time. No exceptions.**
+- **lakehouse-python-sdk** — Lakehouse Python/Shell task engineering: develop, rewrite, optimize, troubleshoot. Covers connector, BulkLoad, IGS, Studio params, datasource, and CREATE TABLE DDL; MUST trigger on: develop/write/create/modify/rewrite/optimize Python or Shell task; BulkLoad batch upload; IGS realtime ingest; connector query/write; Python task error/diagnosis; CREATE TABLE / partition / bucket / index DDL.
+- **lakehouse-doc** — ClickZetta Lakehouse official documentation. Covers SQL syntax, data types, functions, DDL/DML commands, dynamic tables, materialized views, access control, VCluster, data lake, AI functions, etc. When the user writes or asks about SQL syntax or Lakehouse dialect specifics, **MUST** consult lakehouse-doc skill references first to ensure accuracy.
 
-**Step 1 — MUST check LLM first:**
+**If no row matches**: proceed with cz-cli commands directly.
 
-```bash
-cz-cli agent llm show
-```
-
-**Step 2 — If active LLM is configured (kind != "none"), you MUST use agent run:**
-
-```bash
-cz-cli agent run "<request>" --format a2a --dangerously-skip-permissions
-```
-
-Do NOT use direct cz-cli subcommands when an active LLM is available. Always delegate the full request to `cz-cli agent run`.
-
-**Step 3 — ONLY if no active LLM (kind: "none" or empty list), fall back to direct commands:**
+### Rule 2.1 — MUST consult lakehouse-doc skill for SQL commands
 
-Decompose the request into concrete `cz-cli` subcommands (`sql`, `schema`, `table`, `task`, `runs`, `job`, `datasource`, `profile`, etc.), execute them, and synthesize the result.
+When the user request involves any of the following, **MUST** consult **lakehouse-doc** skill references before answering or generating SQL:
 
-Use direct commands for local setup and diagnostics even when agent path is available: `cz-cli profile ...`, `cz-cli -p <profile> status`, `cz-cli agent llm ...`, `cz-cli --help`.
+- Writing, modifying, or optimizing SQL statements (DDL / DML / DQL)
+- Asking about ClickZetta Lakehouse SQL dialect syntax, keywords, or function usage
+- Using data types, type casting, or datetime formats
+- Creating or altering tables, views, materialized views, dynamic tables, external tables
+- Data import/export (COPY INTO, PUT/GET, BulkLoad, Pipe)
+- Access control (GRANT / REVOKE), roles, permissions
+- VCluster configuration and management
+- Index creation and usage (inverted index, BloomFilter, vector index)
+- AI functions, vector search, semantic views
+- Information Schema system view queries
 
-With session continuity:
-
-```bash
-cz-cli agent run "<request>" --format a2a --dangerously-skip-permissions --session <session_id>
-```
+**Rationale**: ClickZetta Lakehouse SQL dialect differs from standard SQL and other databases. Relying on general knowledge may produce incorrect syntax. Consulting lakehouse-doc significantly improves answer accuracy and confidence.
 
-Reuse `session_id` for follow-ups on the same topic. Omit `--session` to start fresh.
+### Rule 3 — Development ends at save; execution requires separate authorization
 
-## Multi-environment (profiles)
+When the user says "develop", "write", "create", or "modify" a task, the work is **complete once the script is saved successfully**.
+After saving, tell the user: "The task has been saved as a draft. Scheduling is not yet active. Let me know explicitly if you want to publish or execute it."
 
-When the user specifies an environment or profile (e.g. "use uat_test", "on the test instance"):
+**Do NOT** auto-publish, auto-trigger execution, or auto-submit a backfill after saving — even if those steps seem like the logical next thing. Every phase that produces a real side effect requires the user to express intent and grant authorization separately.
 
-```bash
-cz-cli agent run "<request>" --profile uat_test --format a2a --dangerously-skip-permissions
-```
+**Exception**: If the user's original request *explicitly* authorized all subsequent steps (e.g. "create and immediately go live", "develop and run it now"), AND Rule 1 already confirmed that intent at the start, the Agent may proceed through the authorized steps without stopping again at each phase. Do not re-ask for confirmation that was already given.
 
-Available profiles: read `~/.clickzetta/profiles.toml` or run `cz-cli profile list`.
+### Rule 3.1 — 补数/回填/重跑历史数据 → `runs refill` (NOT `task`)
 
-## Adding a new profile
+When the user says "补数", "回填", "重跑历史", "backfill", "re-run historical", or "re-process date range":
+- **MUST** use `cz-cli runs refill <task> --from YYYY-MM-DD --to YYYY-MM-DD [-y]`
+- This command is under `runs`, **NOT** under `task` — do not look for it in task subcommands
+- Requires the task to already be published (online); draft tasks cannot be backfilled
 
-**Trigger conditions:** User says "configure new environment", "add profile", "can't connect", mentions an unknown profile name, or provides connection credentials.
+### Rule 4 — Paginated results are not complete data
 
-### Step 1 — Collect information (guided Q&A)
+All `list` commands return only page 1 by default (typically 10 items). The `ai_message` field in the response contains the total count and the command to fetch the next page — treat it as the authoritative next-step hint and follow it. Never treat a first-page result as the full dataset.
 
-If all required fields are already provided, skip directly to Step 2.
+**Pagination termination rules**:
+- If the user only needs "latest / recent N items": stop after page 1, do not paginate.
+- If the user needs the full dataset: paginate until `ai_message` no longer contains a next-page hint.
+- **Safety limit**: auto-paginate at most **3 pages** (≈ 30 items). If more exist, surface the next-page command to the user and ask whether to continue.
 
-Otherwise, ask for missing ones. Accept all at once or prompt one by one.
+### Rule 5 — Always pass explicit task type when creating tasks
 
-**Required fields:**
+When creating a task with `cz-cli task create`, **always** pass `--type` explicitly (`SQL` / `PYTHON` / `SHELL` / `SPARK` / `FLOW`).
+The Python SDK(connector/igs/bulkload) is using from clickzetta import connect instead of Zettapark's session.
 
-| Field | Question to ask | Example |
-|-------|----------------|---------|
-| `service` | Which cloud region? (see table below, or provide the service endpoint directly) | `cn-shanghai-alicloud.api.clickzetta.com` |
-| `instance` | What is the instance name? | `billingsh` |
-| `workspace` | What is the workspace name? | `meter_n_bill` |
-| `username` | What is the username? | `billing_admin` |
-| `password` | What is the password? | — |
-| `name` | What should this profile be named? (suggested format below) | `billingsh` |
+- **MUST NOT** rely on default task type.
+- If user intent says “Python task”, command must include `--type PYTHON`.
+- If `--type FLOW`, immediately switch to Rule 6 — use Flow-specific commands exclusively.
 
-**Common service endpoints (offer as options):**
+### Rule 6 — Flow nodes use Flow-specific tools exclusively
 
-| Region | service | Suggested profile prefix |
-|--------|---------|--------------------------|
-| Alibaba Cloud East China 2 (Shanghai) | `cn-shanghai-alicloud.api.clickzetta.com` | `cn-shanghai` |
-| Tencent Cloud East China (Shanghai) | `ap-shanghai-tencentcloud.api.clickzetta.com` | `ap-shanghai` |
-| Tencent Cloud North China (Beijing) | `ap-beijing-tencentcloud.api.clickzetta.com` | `ap-beijing` |
-| Tencent Cloud South China (Guangzhou) | `ap-guangzhou-tencentcloud.api.clickzetta.com` | `ap-guangzhou` |
-| AWS China (Beijing) | `cn-north-1-aws.api.clickzetta.com` | `cn-north-1` |
+When the operation target is a Flow task or any of its child nodes (`task_type=500`, or user mentions "composite task / flow / workflow"):
 
-**Inference rules (reduce unnecessary questions):**
-- If the user describes a cloud region in natural language (e.g. "Alibaba Cloud Shanghai", "Tencent Cloud Beijing", "阿里云上海", "腾讯云北京"), look up the service endpoint from the table above — do NOT ask the user to provide it again.
-- If the user hasn't provided a profile name, suggest `<prefix>-<instance>` using the prefix from the table (e.g. `cn-shanghai-billingsh`). Confirm with the user or proceed if they don't object.
+- **MUST** use Flow-specific commands: `task flow node-detail`, `task flow node-save`, `task flow node-save-config`, `task flow bind`, `task flow submit`, etc.
+- **MUST NOT** use `task save`, `task save-config`, `task detail`, or `task online` on Flow child nodes — these tools are for regular (non-Flow) tasks only and will produce incorrect results or errors.
+- **Decision rule**: if `task_type == 500` OR the user mentions flow/workflow context → use `task flow *` commands unconditionally.
 
-### Step 2 — Create profile
+### Rule 7 — Always display studio_url in final report
 
-Run `cz-cli profile create` with all collected fields:
+Responses from `task`, `runs`, and `executions` commands may include a `studio_url` field. When present, surface it in the end to the user so they can open the resource directly in Studio.
 
-```bash
-cz-cli profile create <name> \
-  --username <username> \
-  --password <password> \
-  --instance <instance> \
-  --workspace <workspace> \
-  --service <service> \
-  --schema public \
-  --vcluster default
-```
+Display as a Markdown hyperlink: `[View in Studio](https://...)`. Show all studio_url values returned across all commands in the same response — do not deduplicate.
 
-### Step 3 — Verify connection
+### Rule 8 — Maximize execution efficiency: parallel and chained commands
 
-After creating, run:
+**Independent commands → parallel.  Dependent commands → chain with `--field`.**
 
 ```bash
-cz-cli status --profile <name>
-```
-
-A successful response looks like:
-```json
-{"data": {"connected": true, "workspace": "...", "time_ms": ...}}
-```
-
-If it fails, report the error and ask the user to double-check credentials or service endpoint.
-
-## Error handling
+# Async SQL: submit → poll → fetch result → preview first rows
+JOB=$(cz-cli sql "SELECT * FROM orders LIMIT 100" --field job_id) && cz-cli job status $JOB --format toon && cz-cli job result $JOB --format toon | head -12
 
-All errors in non-TTY mode output JSON to stdout:
+# Parallel: two independent lookups at the same time
+cz-cli task content my_task --format toon & cz-cli runs list --task my_task --format toon & wait
 
-```json
-{"ok": false, "error": "NO_PROFILE", "next_steps": ["cz-cli setup --credential <base64>"]}
+# Chain: save then verify
+cz-cli task save-content my_task --file script.sql && cz-cli task content my_task --format toon
 ```
 
-On `NO_PROFILE` error: check if a profile can be configured via username/password (see "Adding a new profile" above). If the user has a base64 credential instead, guide them to run `cz-cli setup --credential <base64>`. See `references/profile-setup.md`.
+Key tools:
+- `--field <name>` — extract one value as raw text: `cz-cli sql "..." --field job_id` → `2026042818122957849079780`
+- `--format toon` — line-per-field output, works with `grep`/`head`
+- `--format json` — single-line JSON, parse in code only (do NOT pipe to grep/head)
+
+**Shortcut**: Use `cz-cli sql --sync "..." > /tmp/res.json` to force synchronous execution (waits for results inline). Prefer `--sync` for simple/fast queries.
+
+## Command Quick Reference

+- `cz-cli runs refill <task> --from D --to D [-y]` — **补数/回填**: re-run scheduled instances for a historical date range (task must be online). `D` accepts `YYYY-MM-DD` (day boundary: `--from` = start of day, `--to` = 23:59:59) or `YYYY-MM-DDTHH:MM:SS` for exact datetime — **use ISO datetime for hourly/minutely tasks** to avoid missing instances
+- `cz-cli attempts list <run_id_or_task>` / `cz-cli attempts log <run_id_or_task> [--attempt-id N]`
+
+### Agent (AI Agent)

 deepseek/deepseek-v4-pro

The previous default "deepseek-v3" doesn't match any registered model name

Subject: [PATCH 212/521] feat(cli): add cz-agent alias for cz-cli agent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`cz-agent` is equivalent to `cz-cli agent` with all arguments passed
through. This provides a shorter command for agent operations:
  cz-agent run "hello"     → cz-cli agent run "hello"
  cz-agent llm show        → cz-cli agent llm show
  cz-agent                 → cz-cli agent (opens TUI)

Closes CZ-ECOCZECO-294.

Subject: [PATCH 216/521] fix(profile): isolate connection verification from
 existing profiles

profile create and quickstart verification was using getExecContext which
calls resolveConnectionConfig. This loads the existing default profile,
and its PAT takes priority over the new profile's username/password in
the auth resolution logic, causing CHECK_ACCESS_TOKEN_FAILED errors.

Now builds a standalone ConnectionConfig directly from the new profile
object, ensuring only the new credentials are used for verification.

 version

The 88c2612b7 commit incorrectly regenerated the cz-cli skill with a
completely different structure. Revert to the original hand-crafted version.
The -o to --format fix in cz-cli-inner was already correct in HEAD.

-# cz-cli Skill
+# cz-cli — ClickZetta Lakehouse Subagent
 
-> [!IMPORTANT]
-> **Fallback**: If `cz-cli` command not present, check for a bundled binary at `scripts/<platform>/cz-cli` (e.g. `scripts/macos-arm64/cz-cli`, `scripts/linux-x86_64/cz-cli`, `scripts/windows-x86_64/cz-cli.exe`). If found, use its absolute path directly. Otherwise run `pip3 install cz-cli -U` then use `cz-cli` from PATH.
+You have no direct Lakehouse access. Always delegate via cz-cli.
 
-## AI Agent Behavior Rules
+## Capabilities
 
-> [!IMPORTANT]
-> Read these rules before invoking any command.
+### SQL & Data Operations
+- Execute any SQL against Lakehouse: SELECT, DDL (CREATE/ALTER/DROP TABLE, SCHEMA, VIEW), DML (INSERT, UPDATE, DELETE, MERGE INTO)
+- Run async jobs and fetch results
+- Preview table data and row counts
 
-### Rule 0 — Initialize connection profile before first use
+### Table & Schema Management
+- List, describe, create, and drop tables and schemas
+- View table history, indexes, partitions, and statistics
+- Add or update column/table comments
+- Create Dynamic Tables for auto-incremental ETL (ODS→DWD→DWS pipelines)
+- Create Materialized Views for pre-computed aggregations
+- Create Table Streams to capture INSERT/UPDATE/DELETE changes for CDC UPSERT
 
-When any command returns error code `NO_PROFILE`, run `cz-cli setup --credential <base64>` if the credential string is available, or read `references/profile-setup.md` and follow the onboarding steps there. Always use the **AskUserQuestion tool** — never ask via plain text.
+### Studio Task Management
+- Create, configure, deploy, and delete Studio tasks (SQL, Shell, Python, integration, flow)
+- Save task content and cron schedule
+- Deploy, undeploy, and execute tasks ad-hoc
+- Monitor run instances: list, detail, wait, logs, stop, rerun, backfill
+- View run statistics and dependencies
 
-### Rule 1 — Clarify intent before any state-changing operation
+### Data Sync Pipelines
+- Create single-table realtime CDC sync tasks (MySQL/PostgreSQL/SQL Server → Lakehouse, task_type=28)
+- Create multi-table or whole-database CDC sync tasks — mirror, merge, or sharded-table consolidation (task_type=281)
+- Create offline batch sync tasks with Cron scheduling — single-table (task_type=10) or multi-table (task_type=291)
+- Manage sync task lifecycle: start, stop, offline, backfill, add tables, re-sync individual tables
 
-When a task involves an operation that changes system state (publishing a schedule, taking a task offline, triggering a run, deleting an object, etc.):
+### Data Ingestion Pipelines
+- Create continuous OSS/S3/COS ingest PIPE (LIST_PURGE scan mode or EVENT_NOTIFICATION mode)
+- Create continuous Kafka ingest PIPE using READ_KAFKA function
+- One-shot file import from URL, local path, or Volume (COPY INTO)
+- Manage PIPE lifecycle: pause, resume, adjust batch interval, view load history
 
-**Do NOT proceed without** explicitly understanding the user's intent on all three points:
-1. **Target**: Which task / table / run instance?
-2. **Purpose**: Why does this need to happen now?
-3. **Side-effect acknowledgment**: Does the user understand the impact (historical re-runs, schedule interruption, permanent deletion, etc.)?
+### Data Recovery
+- Query data at a historical point in time (Time Travel: TIMESTAMP AS OF)
+- Roll back a table to a previous version (RESTORE TABLE)
+- Recover accidentally dropped tables, dynamic tables, or materialized views (UNDROP TABLE)
+- Inspect change history (DESC HISTORY) and deleted objects (SHOW TABLES HISTORY)
+- Configure retention: data_retention_days, data_lifecycle
 
-Use the **AskUserQuestion tool** (not plain text) to confirm with the user, then wait for an explicit reply before executing.
+### Connection & Environment Management
+- Create, update, delete, and switch connection profiles (multi-cloud, multi-region)
+- Check connection status and switch workspace
+- List and test external data sources, browse catalogs and objects
+- Generate Python SDK / ZettaPark / SQLAlchemy / JDBC connection code from profile parameters
 
-Consult **Command Risk Reference** below to determine whether a command qualifies as state-changing.
+## Route to cz-cli
 
+- Any mention of cz-cli, ClickZetta, or Lakehouse
+- SQL against Lakehouse (SELECT, DDL, DML)
+- Studio task development, scheduling, monitoring
+- Data pipelines (sync, import, CDC, streaming)
+- Profile and connection configuration
+- Performance analysis and optimization
 
-### Rule 2 — Route to companion skill BEFORE acting (MUST)
+## Keep in host agent
 
-> [!IMPORTANT]
-> Check this routing table **before** executing any command or writing any code.
-> If the user intent matches a trigger below, **MUST** invoke the listed skill immediately and stop processing in cz-cli.
+- General programming unrelated to ClickZetta
+- Local file operations, git
+- Non-ClickZetta databases (PostgreSQL, MySQL standalone)
 
-The following companion skills are bundled with `cz-cli`:
+## Execution strategy
 
-- **lakehouse-python-sdk** — Lakehouse Python/Shell task engineering: develop, rewrite, optimize, troubleshoot. Covers connector, BulkLoad, IGS, Studio params, datasource, and CREATE TABLE DDL; MUST trigger on: develop/write/create/modify/rewrite/optimize Python or Shell task; BulkLoad batch upload; IGS realtime ingest; connector query/write; Python task error/diagnosis; CREATE TABLE / partition / bucket / index DDL.
-- **lakehouse-doc** — ClickZetta Lakehouse official documentation. Covers SQL syntax, data types, functions, DDL/DML commands, dynamic tables, materialized views, access control, VCluster, data lake, AI functions, etc. When the user writes or asks about SQL syntax or Lakehouse dialect specifics, **MUST** consult lakehouse-doc skill references first to ensure accuracy.
+**MANDATORY: Follow this order every time. No exceptions.**
 
-**If no row matches**: proceed with cz-cli commands directly.
+**Step 1 — MUST check LLM first:**
 
-### Rule 2.1 — MUST consult lakehouse-doc skill for SQL commands
+```bash
+cz-cli agent llm show
+```
+
+**Step 2 — If active LLM is configured (kind != "none"), you MUST use agent run:**
+
+```bash
+cz-cli agent run "<request>" --format a2a --dangerously-skip-permissions
+```
+
+Do NOT use direct cz-cli subcommands when an active LLM is available. Always delegate the full request to `cz-cli agent run`.
+
+**Step 3 — ONLY if no active LLM (kind: "none" or empty list), fall back to direct commands:**
 
-When the user request involves any of the following, **MUST** consult **lakehouse-doc** skill references before answering or generating SQL:
+Decompose the request into concrete `cz-cli` subcommands (`sql`, `schema`, `table`, `task`, `runs`, `job`, `datasource`, `profile`, etc.), execute them, and synthesize the result.
 
-- Writing, modifying, or optimizing SQL statements (DDL / DML / DQL)
-- Asking about ClickZetta Lakehouse SQL dialect syntax, keywords, or function usage
-- Using data types, type casting, or datetime formats
-- Creating or altering tables, views, materialized views, dynamic tables, external tables
-- Data import/export (COPY INTO, PUT/GET, BulkLoad, Pipe)
-- Access control (GRANT / REVOKE), roles, permissions
-- VCluster configuration and management
-- Index creation and usage (inverted index, BloomFilter, vector index)
-- AI functions, vector search, semantic views
-- Information Schema system view queries
+Use direct commands for local setup and diagnostics even when agent path is available: `cz-cli profile ...`, `cz-cli -p <profile> status`, `cz-cli agent llm ...`, `cz-cli --help`.
 
-**Rationale**: ClickZetta Lakehouse SQL dialect differs from standard SQL and other databases. Relying on general knowledge may produce incorrect syntax. Consulting lakehouse-doc significantly improves answer accuracy and confidence.
+With session continuity:
+
+```bash
+cz-cli agent run "<request>" --format a2a --dangerously-skip-permissions --session <session_id>
+```
 
-### Rule 3 — Development ends at save; execution requires separate authorization
+Reuse `session_id` for follow-ups on the same topic. Omit `--session` to start fresh.
 
-When the user says "develop", "write", "create", or "modify" a task, the work is **complete once the script is saved successfully**.
-After saving, tell the user: "The task has been saved as a draft. Scheduling is not yet active. Let me know explicitly if you want to publish or execute it."
+## Multi-environment (profiles)
 
-**Do NOT** auto-publish, auto-trigger execution, or auto-submit a backfill after saving — even if those steps seem like the logical next thing. Every phase that produces a real side effect requires the user to express intent and grant authorization separately.
+When the user specifies an environment or profile (e.g. "use uat_test", "on the test instance"):
 
-**Exception**: If the user's original request *explicitly* authorized all subsequent steps (e.g. "create and immediately go live", "develop and run it now"), AND Rule 1 already confirmed that intent at the start, the Agent may proceed through the authorized steps without stopping again at each phase. Do not re-ask for confirmation that was already given.
+```bash
+cz-cli agent run "<request>" --profile uat_test --format a2a --dangerously-skip-permissions
+```
 
-### Rule 3.1 — 补数/回填/重跑历史数据 → `runs refill` (NOT `task`)
+Available profiles: read `~/.clickzetta/profiles.toml` or run `cz-cli profile list`.
 
-When the user says "补数", "回填", "重跑历史", "backfill", "re-run historical", or "re-process date range":
-- **MUST** use `cz-cli runs refill <task> --from YYYY-MM-DD --to YYYY-MM-DD [-y]`
-- This command is under `runs`, **NOT** under `task` — do not look for it in task subcommands
-- Requires the task to already be published (online); draft tasks cannot be backfilled
+## Adding a new profile
 
-### Rule 4 — Paginated results are not complete data
+**Trigger conditions:** User says "configure new environment", "add profile", "can't connect", mentions an unknown profile name, or provides connection credentials.
 
-All `list` commands return only page 1 by default (typically 10 items). The `ai_message` field in the response contains the total count and the command to fetch the next page — treat it as the authoritative next-step hint and follow it. Never treat a first-page result as the full dataset.
+### Step 1 — Collect information (guided Q&A)
 
-**Pagination termination rules**:
-- If the user only needs "latest / recent N items": stop after page 1, do not paginate.
-- If the user needs the full dataset: paginate until `ai_message` no longer contains a next-page hint.
-- **Safety limit**: auto-paginate at most **3 pages** (≈ 30 items). If more exist, surface the next-page command to the user and ask whether to continue.
+If all required fields are already provided, skip directly to Step 2.
 
-### Rule 5 — Always pass explicit task type when creating tasks
+Otherwise, ask for missing ones. Accept all at once or prompt one by one.
 
-When creating a task with `cz-cli task create`, **always** pass `--type` explicitly (`SQL` / `PYTHON` / `SHELL` / `SPARK` / `FLOW`).
-The Python SDK(connector/igs/bulkload) is using from clickzetta import connect instead of Zettapark's session.
+**Required fields:**
 
-- **MUST NOT** rely on default task type.
-- If user intent says “Python task”, command must include `--type PYTHON`.
-- If `--type FLOW`, immediately switch to Rule 6 — use Flow-specific commands exclusively.
+| Field | Question to ask | Example |
+|-------|----------------|---------|
+| `service` | Which cloud region? (see table below, or provide the service endpoint directly) | `cn-shanghai-alicloud.api.clickzetta.com` |
+| `instance` | What is the instance name? | `billingsh` |
+| `workspace` | What is the workspace name? | `meter_n_bill` |
+| `username` | What is the username? | `billing_admin` |
+| `password` | What is the password? | — |
+| `name` | What should this profile be named? (suggested format below) | `billingsh` |
 
-### Rule 6 — Flow nodes use Flow-specific tools exclusively
+**Common service endpoints (offer as options):**
 
-When the operation target is a Flow task or any of its child nodes (`task_type=500`, or user mentions "composite task / flow / workflow"):
+| Region | service | Suggested profile prefix |
+|--------|---------|--------------------------|
+| Alibaba Cloud East China 2 (Shanghai) | `cn-shanghai-alicloud.api.clickzetta.com` | `cn-shanghai` |
+| Tencent Cloud East China (Shanghai) | `ap-shanghai-tencentcloud.api.clickzetta.com` | `ap-shanghai` |
+| Tencent Cloud North China (Beijing) | `ap-beijing-tencentcloud.api.clickzetta.com` | `ap-beijing` |
+| Tencent Cloud South China (Guangzhou) | `ap-guangzhou-tencentcloud.api.clickzetta.com` | `ap-guangzhou` |
+| AWS China (Beijing) | `cn-north-1-aws.api.clickzetta.com` | `cn-north-1` |
 
-- **MUST** use Flow-specific commands: `task flow node-detail`, `task flow node-save`, `task flow node-save-config`, `task flow bind`, `task flow submit`, etc.
-- **MUST NOT** use `task save`, `task save-config`, `task detail`, or `task online` on Flow child nodes — these tools are for regular (non-Flow) tasks only and will produce incorrect results or errors.
-- **Decision rule**: if `task_type == 500` OR the user mentions flow/workflow context → use `task flow *` commands unconditionally.
+**Inference rules (reduce unnecessary questions):**
+- If the user describes a cloud region in natural language (e.g. "Alibaba Cloud Shanghai", "Tencent Cloud Beijing", "阿里云上海", "腾讯云北京"), look up the service endpoint from the table above — do NOT ask the user to provide it again.
+- If the user hasn't provided a profile name, suggest `<prefix>-<instance>` using the prefix from the table (e.g. `cn-shanghai-billingsh`). Confirm with the user or proceed if they don't object.
 
-### Rule 7 — Always display studio_url in final report
+### Step 2 — Create profile
 
-Responses from `task`, `runs`, and `executions` commands may include a `studio_url` field. When present, surface it in the end to the user so they can open the resource directly in Studio.
+Run `cz-cli profile create` with all collected fields:
 
-Display as a Markdown hyperlink: `[View in Studio](https://...)`. Show all studio_url values returned across all commands in the same response — do not deduplicate.
+```bash
+cz-cli profile create <name> \
+  --username <username> \
+  --password <password> \
+  --instance <instance> \
+  --workspace <workspace> \
+  --service <service> \
+  --schema public \
+  --vcluster default
+```
 
-### Rule 8 — Maximize execution efficiency: parallel and chained commands
+### Step 3 — Verify connection
 
-**Independent commands → parallel.  Dependent commands → chain with `--field`.**
+After creating, run:
 
 ```bash
-# Async SQL: submit → poll → fetch result → preview first rows
-JOB=$(cz-cli sql "SELECT * FROM orders LIMIT 100" --field job_id) && cz-cli job status $JOB --format toon && cz-cli job result $JOB --format toon | head -12
+cz-cli status --profile <name>
+```
+
+A successful response looks like:
+```json
+{"data": {"connected": true, "workspace": "...", "time_ms": ...}}
+```
+
+If it fails, report the error and ask the user to double-check credentials or service endpoint.
+
+## Error handling
 
-# Parallel: two independent lookups at the same time
-cz-cli task content my_task --format toon & cz-cli runs list --task my_task --format toon & wait
+All errors in non-TTY mode output JSON to stdout:
 
-# Chain: save then verify
-cz-cli task save-content my_task --file script.sql && cz-cli task content my_task --format toon
+```json
+{"ok": false, "error": "NO_PROFILE", "next_steps": ["cz-cli setup --credential <base64>"]}
 ```
 
-Key tools:
-- `--field <name>` — extract one value as raw text: `cz-cli sql "..." --field job_id` → `2026042818122957849079780`
-- `--format toon` — line-per-field output, works with `grep`/`head`
-- `--format json` — single-line JSON, parse in code only (do NOT pipe to grep/head)
-
-**Shortcut**: Use `cz-cli sql --sync "..." > /tmp/res.json` to force synchronous execution (waits for results inline). Prefer `--sync` for simple/fast queries.

Subject: [PATCH 219/521] fix(provider): honor default_llm when resolving
 default model

Previously, when default_llm was set in profiles.toml but the entry had
no model field, agent run and the TUI would silently fall back to a
recently-used model from a different LLM (e.g. picking gpt-5.5 from a
relay entry while default_llm pointed at clickzetta). Recent history was
checked against the full provider catalog and ignored the user's
explicit default_llm preference.

Centralizes the priority logic in a new pure function resolveDefaultModel
shared by provider.ts (agent run) and the TUI fallbackModel. Priority:
explicit --model, cfg.model, default_llm entry's provider best model,
recent (only when default_llm is unset), then any allowed provider.

When default_llm is set, recent history is skipped entirely so a stale
TUI selection cannot override the configured default.

Adds 14 unit tests covering single/multi entry, with/without entry
model, default_llm set/unset, recent cross-pollution, invalid refs,
and explicit-trust semantics for both call sites.

Subject: [PATCH 220/521] fix(tui): stop overwriting profiles.toml when
 switching model

Selecting a model in the /model dialog used to call persistDefaultLlmModel,
which wrote the chosen model id back into [llm.<default>].model in
profiles.toml. This conflated transient UI state with persistent config:
a one-off model swap permanently mutated the configuration file the user
edited by hand.

Selections now go to the runtime recent list only (model.json). Persistent
defaults remain controlled by profiles.toml directly or by
`cz-cli agent llm` commands.

Subject: [PATCH 221/521] fix(tui): only disable copy-on-select by default on
 windows

CLICKZETTA_EXPERIMENTAL_DISABLE_COPY_ON_SELECT defaulted to true on every
platform, leaving macOS and Linux users without the standard click-drag
copy behavior they expect from a terminal UI. The flag exists primarily
to work around a Windows-specific selection issue; gating the default on
process.platform === "win32" restores native behavior elsewhere while
keeping the workaround where it is needed.

Subject: [PATCH 223/521] docs: design spec for agent run async non-TTY mode

Add design document and skill documentation for making `cz-cli agent run`
work asynchronously in non-TTY environments. The async mode returns a
session_id immediately and allows callers to poll status and retrieve
full conversation history (thinking, tool calls, text) via export.

+# cz-cli agent run — 异步 Non-TTY 模式设计
+
+## 概述
+
+在 non-TTY 环境下（如被外部 AI agent 调用时），`cz-cli agent run` 应以 fire-and-forget 语义执行：立即返回 session_id，调用方后续通过 session_id 查询状态并获取完整对话信息（含 thinking、tool_call、text 等全部 parts）。
+
+## 动机
+
+当 `cz-cli agent run` 作为 subagent 被 Claude Code 等外部 AI agent 调用时：
+- 当前 a2a 模式会阻塞到 session 完成才返回结果
+- 长时间运行的任务会导致调用方超时
+- 调用方无法在任务运行中获取中间状态
+
+异步模式允许：
+1. 调用方快速获得 session_id 句柄
+2. 按需轮询任务状态
+3. 任务完成后拉取完整对话历史（含所有 parts 类型）
+
+## 触发条件
+
+异步模式在以下**任一**条件满足时激活：
+
+| 条件 | 场景 |
+|------|------|
+| `--async` flag 显式传入 | TTY 和 non-TTY 下均可使用 |
+| `!process.stdout.isTTY` 且 `--format` 为 `a2a` 或 `json` | 管道/CI/subagent 自动检测 |
+
+优先级：`--async` flag 优先于 TTY 检测。若 `--no-async`（或未来需要），在 non-TTY 下仍可强制同步等待。
+
+## API 设计
+
+### Phase 1: 异步提交
+
+```bash
+# 显式
+cz-cli agent run "analyze sales table" --async --format a2a --dangerously-skip-permissions
+
+# 隐式（管道场景，stdout 非 TTY）
+echo "analyze sales table" | cz-cli agent run --format a2a --dangerously-skip-permissions
+```
+
+**stdout 输出：**
+```json
+{
+  "session_id": "01JXF3K...",
+  "status": "running",
+  "message": "Session submitted asynchronously"
+}
+```
+
+进程以 exit code 0 退出。
+
+### Phase 2: 状态查询
+
+```bash
+cz-cli agent session status <session_id>
+```
+
+**输出：**
+```json
+{
+  "session_id": "01JXF3K...",
+  "status": "idle",
+  "updated_at": 1748160000000
+}
+```
+
+状态值：
+- `"busy"` — 任务运行中
+- `"idle"` — 任务完成
+
+### Phase 3: 获取完整对话
+
+```bash
+cz-cli agent export <session_id>
+```
+
+**输出结构（现有 export 命令，无需修改）：**
+```json
+{
+  "info": {
+    "id": "01JXF3K...",
+    "title": "analyze sales table",
+    "directory": "/path/to/project",

+
+## 实现变更
+
+### 1. 新增 `--async` flag
+
+**文件：** `packages/cz-cli/src/commands/agent.ts`
+
+在 `run` 子命令的 builder 中新增：
+```typescript
+.option("async", {
+  type: "boolean",
+  describe: "Submit asynchronously and return session ID immediately (default in non-TTY with a2a/json format)"
+})
+```
+
+### 2. 修改 run command handler
+
+**文件：** `packages/opencode/src/cli/cmd/run.ts`
+
+在 `execute()` 函数中，判断异步模式：
+
+```typescript
+const isAsync = args.async || (!process.stdout.isTTY && (args.format === "a2a" || args.format === "json"))
+
+if (isAsync) {
+  // 1. 创建 session
+  const sessionID = await session(sdk)
+  if (!sessionID) {
+    process.stdout.write(JSON.stringify({ error: "Session not found" }) + EOL)
+    process.exit(1)
+  }
+
+  // 2. 异步提交 prompt（fire-and-forget）
+  await sdk.session.promptAsync({
+    sessionID,
+    agent,
+    model: args.model ? Provider.parseModel(args.model) : undefined,
+    variant: args.variant,
+    parts: [...files, { type: "text", text: message }],
+  })
+
+  // 3. 立即返回 session_id
+  const output = {
+    session_id: sessionID,
+    status: "running",
+    message: "Session submitted asynchronously",
+  }
+  process.stdout.write(JSON.stringify(output) + EOL)
+  return
+}
+```
+
+### 3. 确保 agent runtime 在异步提交后不退出
+
+当使用 `--async` 时，`bootstrap()` 启动的 agent runtime 需要在后台继续运行以处理 session。
+
+两种策略：
+- **attach 模式（推荐）：** 如果已有 agent server 运行，直接 attach 并提交，server 继续处理
+- **detach 模式：** 如果没有 server，启动 server 后 detach CLI 进程（server 作为 daemon 继续运行）
+
+现有架构中 `bootstrap()` 会启动一个 in-process server。异步模式下需要确保：
+1. 如果有已运行的 server（通过 lock file 检测），使用 `--attach` 连接
+2. 如果没有，启动 server 并在 prompt 提交后让 server 继续运行（不随 CLI 退出而终止）
+
+### 4. main.ts 参数传递
+
+**文件：** `packages/opencode/src/main.ts`
+
+确保 `--async` flag 被正确解析并传递到 RunCommand handler。

+## 边界条件
+
+1. **session 已 busy：** `promptAsync` 会返回错误，CLI 应输出 `{error: "session busy"}`
+2. **server 未运行：** 异步模式需要 server 在后台运行。如果没有 server，CLI 应启动一个 detached server 或报错引导用户先启动
+3. **超时：** 调用方自行决定 poll 间隔和超时策略
+4. **权限请求：** 异步模式下必须配合 `--dangerously-skip-permissions`，否则 session 会卡在 permission.asked 状态

 Reuse `session_id` for follow-ups on the same topic. Omit `--session` to start fresh.
 
+## Async mode (non-TTY / long-running tasks)
+
+When running in non-TTY environments (e.g. as a subagent from Claude Code) or for long-running tasks, use async mode to avoid blocking:
+
+### Submit asynchronously
+
+```bash
+cz-cli agent run "<request>" --async --format a2a --dangerously-skip-permissions
+```
+
+Returns immediately with a session ID:
+```json
+{"session_id": "01JXF3K...", "status": "running", "message": "Session submitted asynchronously"}
+```
+
+Note: In non-TTY with `--format a2a` or `--format json`, async mode activates automatically (no `--async` flag needed).
+
+### Poll status
+
+```bash
+cz-cli agent session status <session_id>
+```
+
+Returns:
+```json
+{"session_id": "01JXF3K...", "status": "idle", "updated_at": 1748160000000}
+```
+
+- `"busy"` = still running
+- `"idle"` = completed
+
+### Retrieve full conversation (thinking + tool calls + text)
+
+```bash
+cz-cli agent export <session_id>
+```
+
+Returns complete session with all message parts:
+```json
+{
+  "info": { "id": "...", "title": "...", "time": {...} },
+  "messages": [
+    {
+      "info": { "role": "user" },

+        { "type": "text", "text": "final answer..." }
+      ]
+    }
+  ]
+}
+```
+
+Part types in export:
+- `reasoning` — LLM thinking/reasoning blocks
+- `tool` — tool calls with full input/output (bash, read, write, edit, glob, grep, etc.)
+- `text` — final text response
+- `step-start` / `step-finish` — step boundaries
+- `patch` — code diffs
+- `subtask` — delegated sub-tasks
+
+### Async workflow pattern
+
+```bash
+# 1. Submit
+SESSION=$(cz-cli agent run "complex analysis" --async --format a2a --dangerously-skip-permissions | jq -r '.session_id')
+
+# 2. Poll until done
+while [ "$(cz-cli agent session status $SESSION | jq -r '.status')" = "busy" ]; do
+  sleep 5
+done
+
+# 3. Get full result
+cz-cli agent export $SESSION
+```
+
+### With session continuity (async)
+
+```bash
+# First turn
+SESSION=$(cz-cli agent run "describe sales table" --async --format a2a --dangerously-skip-permissions | jq -r '.session_id')
+# ... wait for completion ...
+
+# Follow-up turn on same session
+cz-cli agent run "now show row counts" --async --format a2a --dangerously-skip-permissions --session $SESSION
+```
+
+### Important notes for async mode
+
+- **Permissions:** Always use `--dangerously-skip-permissions` — async mode cannot handle interactive permission prompts
+- **Server requirement:** An agent runtime server must be running (or will be started automatically)
+- **Error handling:** If session is already busy, returns `{"error": "session busy"}`
+

+# Session Status Progress Line — Design
+
+## Overview
+
+Add a single-line human-readable progress indicator to `cz-cli agent session status <sessionID>` output (when busy) or the final text result (when idle), so external host agents (like Claude Code) can know what cz-cli is currently doing through polling alone, without needing additional commands.
+
+To ensure TTY rendering and progress rendering stay consistent when new tools are added, extract the "data computation" portion of the 12 tool-specific render functions in `run.ts` into a pure function `describePart()`, used by both the TTY path and the status path.
+
+## Motivation
+
+The current `agent session status` only returns `idle | busy`. The host agent cannot see "what step is currently executing." For details, it must run `agent export` to dump the entire session.
+
+Requirements:
+
+1. **Visible progress** — When busy, see at a glance what's happening (which tool, which command, whether it's thinking, whether it's retrying)
+2. **Ready-to-use completion** — When idle, get the final text reply directly without going through `export`
+3. **Future-proof** — TTY rendering and progress rendering share a single source of truth; adding a new tool won't drift between them
+
+## Non-goals
+
+- No SSE / streaming push (poll model is sufficient)
+- No cursor-based incremental part fetch (use `export` for full data)
+- No type-filter or grep on parts (use `export | jq` for complex queries)
+- Don't expose the SQLite path for direct external reads (keep CLI as the stable contract)
+
+## Design
+
+### Data flow
+
+```
+┌──────────────────┐     ┌────────────────────────┐
+│ session status   │ ──> │ Query SQLite           │
+│ <sessionID>      │     │  - SessionStatus.get() │
+└──────────────────┘     │  - PartTable latest    │
+                         │  - PartTable last text │
+                         └───────────┬────────────┘
+                                     │

+                          │ → {icon, title, …}  │  shared by TTY & status
+                          └──────────┬──────────┘
+                                     │
+                          ┌──────────▼──────────┐
+                          │ progressLine()      │
+                          │ → "$ cz-cli ..."    │
+                          └─────────────────────┘
+```
+
+### Three core deliverables
+
+1. **Pure renderer module** — new `render.ts` with `describePart()` and `progressLine()`
+2. **Session Service helpers** — add `latestPart()` and `lastTextPart()` to `Session.Service`
+3. **TTY thin-shell refactor** — `run.ts` 12 tool functions delegate to `describePart`
+4. **`session status` enhancement** — handler uses the new Service helpers + `progressLine`
+
+#### 1. `describePart()` pure function (new file `packages/opencode/src/session/render.ts`)
+
+```typescript
+export type PartDescription = {
+  icon: string                  // single-character icon: "$" "→" "✱" "💭" "✏" "▶" "✓" "↻"
+  title: string                 // main title, e.g. "cz-cli table list -o table"
+  description?: string          // optional subtitle, e.g. "3 matches"
+  output?: string               // multi-line content (bash output, todo list); TTY-only
+}
+
+export function describePart(part: MessageV2.Part): PartDescription
+```
+
+Covers all 12 part types (see Part Rendering Map below).
+
+#### 2. TTY thin-shell refactor (modify `packages/opencode/src/cli/cmd/run.ts`)
+
+The 12 tool-specific functions (`bash()`, `read()`, `grep()`, etc.) become:
+
+```typescript
+function bash(info: ToolProps<typeof BashTool>) {
+  const d = describePart(info.part)
+  block({ icon: d.icon, title: d.title, description: d.description }, d.output)
+}
+function read(info: ToolProps<typeof ReadTool>) {
+  inline(describePart(info.part))
+}
+// ... all 12 functions become 2-3 lines of dispatch
+```
+
+`inline()` / `block()` themselves remain unchanged and continue to apply ANSI styling internally. ANSI does not enter `describePart`'s domain.
+
+#### 3. `session status` enhancement (modify `packages/opencode/src/cli/cmd/session.ts`)
+
+Two new helper queries are needed; we add them as Session Service methods (next to existing `getPart`):
+
+```typescript
+// In packages/opencode/src/session/session.ts (Service interface)
+readonly latestPart: (sessionID: SessionID) => Effect.Effect<MessageV2.Part | undefined>
+readonly lastTextPart: (sessionID: SessionID) => Effect.Effect<MessageV2.TextPart | undefined>
+```
+
+Implementation uses Drizzle queries on `PartTable`, ordering by `time_created DESC`, limit 1, optionally filtering `data->>'$.type' = 'text'` for `lastTextPart`. SQLite supports JSON path expressions natively, so the type filter is a single WHERE clause without app-side filtering.
+
+Then the status command handler:
+
+```typescript
+export const SessionStatusCommand = cmd({
+  command: "status <sessionID>",
+  handler: async (args) => {
+    await bootstrap(process.cwd(), async () => {
+      const sessionID = SessionID.make(args.sessionID)
+
+      // Verify session exists
+      try {
+        await AppRuntime.runPromise(Session.Service.use((svc) => svc.get(sessionID)))
+      } catch {
+        process.stdout.write(JSON.stringify({ session_id: args.sessionID, error: "Session not found" }) + EOL)
+        process.exit(1)
+      }
+
+      // Query session runtime status
+      const status = await AppRuntime.runPromise(SessionStatus.Service.use((svc) => svc.get(sessionID)))
+
+      // busy / retry: include progress line
+      if (status?.type === "busy" || status?.type === "retry") {
+        const latest = await AppRuntime.runPromise(
+          Session.Service.use((svc) => svc.latestPart(sessionID))
+        )
+        const out: Record<string, unknown> = {
+          session_id: args.sessionID,
+          status: status.type,
+        }
+        if (latest) out.progress = progressLine(latest)
+        if (status.type === "retry") {
+          out.retry = { attempt: status.attempt, message: status.message, next: status.next }
+        }
+        process.stdout.write(JSON.stringify(out) + EOL)
+        return
+      }
+
+      // idle: include final text reply
+      const lastText = await AppRuntime.runPromise(
+        Session.Service.use((svc) => svc.lastTextPart(sessionID))
+      )
+      process.stdout.write(JSON.stringify({
+        session_id: args.sessionID,
+        status: "idle",
+        result: lastText?.text ?? null,
+      }) + EOL)
+    })
+  },
+})
+```
+
+### Part rendering map
+
+| Part type | icon | title template | description | output |
+|-----------|------|---------------|-------------|--------|
+| `tool` bash | `$` | `${command}` | — | `state.output` (when completed) |
+| `tool` read | `→` | `Read ${filePath}` | other input fields `[k=v, ...]` | — |
+| `tool` write | `←` | `Write ${filePath}` | — | `state.output` |
+| `tool` edit | `←` | `Edit ${filePath}` | — | `metadata.diff` |
+| `tool` glob | `✱` | `Glob "${pattern}"` | `in ${path} · ${count} matches` | — |
+| `tool` grep | `✱` | `Grep "${pattern}"` | `in ${path} · ${matches} matches` | — |
+| `tool` webfetch | `%` | `WebFetch ${url}` | — | — |
+| `tool` codesearch | `◇` | `Exa Code Search "${query}"` | — | — |
+| `tool` websearch | `◈` | `Exa Web Search "${query}"` | — | — |
+| `tool` task | `•`/`✗`/`✓` | `${description ?? agent + " Task"}` | `${agent} Agent` | — |
+| `tool` skill | `→` | `Skill "${name}"` | — | — |
+| `tool` todowrite | `#` | `Todos` | — | todo list lines |
+| `tool` other | `⚙` | `${tool} ${title \|\| ""}` | — | — |
+| `text` | `✏` | `Generating response...` | — | — |
+| `reasoning` | `💭` | `Thinking...` | — | — |
+| `step-start` | `▶` | `Calling LLM...` | — | — |
+| `step-finish` | `✓` | `Step done (${reason})` | — | — |
+| `retry` | `↻` | `Retry (attempt ${attempt})` | — | — |
+| `compaction` | `🗜` | `Compacting context...` | — | — |
+| `patch` | `±` | `Patch (${files.length} files)` | — | — |
+| `snapshot` | `◷` | `Snapshot` | — | — |
+| `subtask` | `◔` | `Subtask: ${description}` | — | — |
+| `agent` | `@` | `Agent ${name}` | — | — |
+| `file` | `📎` | `File ${filename ?? ""}` | — | — |
+
+`progressLine()` outputs `${icon} ${title}` or `${icon} ${title} · ${description}`. The `output` field is only consumed by the TTY path's `block()`; progress always ignores it.
+
+### Part state handling
+
+The `tool` type has 4 states: `pending` / `running` / `completed` / `error`.
+
+- `task` tool: icon depends on status (running=`•`, completed=`✓`, error=`✗`) — existing behavior, preserved
+- Other tools: icon does not depend on status — existing behavior, preserved
+
+`bash` in completed state puts `state.output` into the `output` field; TTY shows the output, progress ignores it.
+
+## Output examples
+
+### busy (running)
+
+```bash
+$ cz-cli agent session status ses_xxx
+{"session_id":"ses_xxx","status":"busy","progress":"$ cz-cli table list -o table"}
+
+$ cz-cli agent session status ses_xxx   # a few seconds later
+{"session_id":"ses_xxx","status":"busy","progress":"💭 Thinking..."}
+
+$ cz-cli agent session status ses_xxx   # a few more seconds later
+{"session_id":"ses_xxx","status":"busy","progress":"✱ Grep \"error\" · 3 matches"}
+```
+
+### retry (retrying)
+
+```bash
+$ cz-cli agent session status ses_xxx
+{"session_id":"ses_xxx","status":"retry","progress":"↻ Retry (attempt 2)","retry":{"attempt":2,"message":"rate_limit","next":1748160300000}}
+```
+
+### idle (completed)
+
+```bash
+$ cz-cli agent session status ses_xxx
+{"session_id":"ses_xxx","status":"idle","result":"Here are the results:\n\n**CZ_ Environment Variables:**\n..."}
+```
+
+### Session not found
+
+```bash
+$ cz-cli agent session status ses_invalid
+{"session_id":"ses_invalid","error":"Session not found"}
+```
+
+## Compatibility
+
+### TTY behavior is preserved
+
+`describePart` only extracts the existing "compute icon/title/description/output" logic from the current functions. The TTY path still calls `inline()` / `block()` exactly as before. Visual output is identical to pre-refactor — this is the key validation point in tests.
+
+### Existing SDK / API are untouched
+
+- `agent run` synchronous path, async path, a2a output: **unchanged**
+- SDK `event.subscribe()` / `session.prompt()` / `session.promptAsync()`: **unchanged**
+- Database schema: **unchanged**
+- `agent export` output: **unchanged**
+
+Only `agent session status` JSON output changes from `{session_id, status, updated_at}` to `{session_id, status, progress?, result?, retry?}`. This is an additive change — existing callers reading the `status` field still work, with new optional fields available.
+
+The `updated_at` field is meaningless in the new design (it just reflected the query time), so it's removed — this is the **only breaking change**, but no external caller depends on it yet (this command was added in the previous round and is unreleased).
+
+### Performance
+
+- `session status` adds 1-2 lightweight SQL queries (latest part, last text part), both hitting the primary key + session_id index. SQLite WAL mode does not block writes.
+- `describePart` is pure string concatenation, sub-millisecond
+- Total status query should complete in <50ms
+
+## Error handling
+
+| Scenario | Output | exit code |
+|----------|--------|-----------|
+| Session not found | `{"session_id":"...","error":"Session not found"}` | 1 |
+| Session exists but no parts (just created) | `{"session_id":"...","status":"idle","result":null}` | 0 |
+| `describePart` encounters unknown type | `{icon: "·", title: type}` fallback, no exception | 0 |
+| Database read failure | Throws, falls into existing error handler | 1 |
+
+## Test strategy
+
+### Unit tests
+
+New file `packages/opencode/test/session/render.test.ts`:
+
+- One test case per part type, asserting `describePart` returns icon/title/description/output matching the rendering map
+- `progressLine` concatenation: with description uses ` · `, without description outputs only `${icon} ${title}`
+- Edge cases: missing tool input fields don't crash (e.g. `bash` with no command)
+- Unknown part type hits the fallback branch
+
+### TTY non-regression
+
+In `packages/opencode/test/cli/run-display.test.ts` (modify if exists, create if not):
+- Simulate a part stream, assert TTY output contains expected icon + title text
+- Pre-refactor and post-refactor output is byte-for-byte identical (unless ANSI styling is intentionally changed; this design does not touch ANSI)
+
+### E2E surface
+
+`packages/cz-cli/test/e2e-command-surface.ts` adds:
+- `cz-cli agent session status <fake-id>` falls into NO_ACTIVE_LLM path (existing)
+- `cz-cli agent session status <real-id>` (without LLM configured) returns idle or not-found correctly
+
+## Implementation order (preserves existing functionality)
+
+Commit in this order; each step ships independently without breakage:
+
+1. **New `render.ts`** — Add `describePart` and `progressLine` with full unit tests. `run.ts` still uses old logic, no behavior change.
+2. **Add `latestPart` / `lastTextPart` to Session Service** — Pure data accessors; no caller yet. Unit-tested via fixtures.
+3. **Convert `run.ts` to thin shells** — All 12 tool functions plus reasoning/text/step renderers call `describePart`. Run TTY regression tests; confirm output unchanged.
+4. **Enhance `session status`** — In the handler, query latest part and last text part, call `progressLine` to build the `progress` field.
+5. **Update cz-cli skill docs** — In `skills/cz-cli/SKILL.md`'s "Async mode" section, document the `progress` field.
+
+Each step is its own commit; each step builds and runs tests. If step 3 introduces a TTY visual regression, revert step 3 alone while keeping steps 1-2 (pure functions / data accessors have no side effects).
+
+## Out of scope
+
+- `session status` exposing token / cost totals (could later add `stats: {cost, tokens}` to idle output)
+- `session parts` command (cursor-based incremental fetch, considered in the previous design version, dropped)
+- Structured phase info in `progress` (e.g. `{kind: "tool", label: "..."}`, unnecessary complexity)
+- i18n (progress strings are English, following OpenCode TTY status quo)

Subject: [PATCH 230/521] feat(session): add pure describePart/progressLine
 renderer

Single source of truth for rendering parts as one-line progress strings.
TTY rendering and session status will both consume this; ANSI styling
remains a TTY-side concern.

Subject: [PATCH 232/521] refactor(run): TTY tool rendering uses shared
 describePart

The 12 tool-specific render functions are replaced by a single dispatcher
that delegates data computation to describePart() and only handles ANSI
styling here. Visual output is byte-for-byte identical.

Subject: [PATCH 233/521] feat(session): status returns progress (busy/retry)
 or result (idle)

When busy or retrying, includes a one-line progress string rendered from
the latest part. When idle, includes the final text reply directly so
callers do not need to follow up with agent export.

Removes the meaningless updated_at field (always reflected query time, not
session state).

Also fixes run-cli.ts to gate agent session subcommands on NO_ACTIVE_LLM,
matching the expectation added in commit 0ff0a0b55 (the test was failing
before this task).

Subject: [PATCH 234/521] docs(cz-cli): document progress and result fields in
 session status

Updates the async-mode polling section to reflect the new behavior:
session status returns a one-line progress string (busy/retry) or the
final text reply (idle). The 'updated_at' field that previously appeared
has been removed.

Subject: [PATCH 235/521] fix(session): real-world hardening for async session
 status
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After integration testing against real LLM scenarios, three correctness gaps
were found and fixed:

1. lastTextPart returned user prompts when LLM never produced an assistant
   reply (e.g. ProviderModelNotFoundError before message creation), making
   session status falsely report the user prompt as the LLM result.
   Fix: replaced with latestMessage() that derives result from the last
   assistant message's text parts, surfaces assistant errors as {error},
   and reports NoAssistantResponse when only a user message exists.

2. Cross-process busy detection was broken — SessionStatus.Service is
   per-process in-memory, so polling from a separate CLI invocation
   always saw "idle". Fix: derive busy from the database — assistant
   message in flight (no finish, no error) or fresh user message within
   30s indicates busy. Falls back to in-memory state when available.

3. renderTool lost the try/catch safety net during the run.ts refactor.
   Restored a last-resort fallback so a malformed part can never break
   the streaming loop.

Verified end-to-end with real Anthropic LLM:
- Submit + poll across separate CLI processes → busy/progress visible
- Tool calls render as "$ <command>", "✓ Step done", etc. in real time
- Final result extracted cleanly: {status:"idle", result:"..."}
- LLM failures surface as {status:"idle", error:{name, message}}

Subject: [PATCH 236/521] fix(session): smart progress walk-back skips low-info
 parts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously `progress` showed the literal latest part, which produced two
ugly cases during real polling:

  1. "$ " (empty title) — caught while a bash tool was still in `pending`
     state with state.input.command not yet streamed in.
  2. "✓ Step done (tool-calls)" repeated across multiple polls — between
     LLM steps, the latest part is a step-finish, which carries no useful
     activity signal.

Fix: walk back through the most recent 20 parts and pick the first one
that describes real activity. Skips:
  - step-start / step-finish (boundary markers)
  - tool parts in `pending` state with empty primary input field
    (bash w/o command, read w/o filePath, grep w/o pattern, etc.)

Falls back to the literal latest part if nothing informative is found.

Adds Session.Service.recentParts(sessionID, limit) accessor and tests.

Verified with real LLM flow:
  before: $ ; ✓ Step done; ✓ Step done; ✓ Step done; ...
  after:  $ sleep 3 && echo first; $ sleep 3 && echo second; ...

Subject: [PATCH 237/521] fix(render): surface todo summary + active task in
 progress line
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

todowrite previously rendered as just "# Todos" — fully throwing away
the todo content during status polling. Output field carried the lines
but progressLine ignores output (it's TTY-only).

Compute a one-line summary in the description field:
  - "# Todos · 2/5 done · in-progress: load skill" (when any task is in
    in_progress state — surfaces the active task title)
  - "# Todos · 3/3 done · 0 pending"               (no active task)

Real polling now shows:
  before: # Todos
          # Todos
  after:  # Todos · 0/3 done · in-progress: Run df -h to check disk usage
          # Todos · 3/3 done · 0 pending

Subject: [PATCH 238/521] fix(render): make skill tool title consistent with
 other tool verbs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Original "Skill \"<name>\"" had no verb, unlike Read/Write/Glob/Grep/WebFetch.
Changed to "Load skill \"<name>\"" for consistency and clarity — the operation
is "load a skill" rather than just naming a skill.

Before:  → Skill "cz-cli-inner"
After:   → Load skill "cz-cli-inner"

Subject: [PATCH 239/521] docs(skill): teach host agent to use session status /
 export
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Updates the cz-cli SKILL.md and the --help describe text for `agent
session status` so a host agent (Claude Code, automation scripts) knows
the new way to inspect an async run:

  - `cz-cli agent session status <session_id>` returns one of:
      * busy/retry — with a `progress` one-liner
      * idle — with the final `result` text
      * error — with structured failure info
  - `cz-cli agent export <session_id>` returns the full conversation
    (messages, tool calls, reasoning, text). Wait until status is idle
    before exporting.

Workflow details (poll cadence, parsing, etc.) are left to the host
agent's discretion — the skill only documents the available primitives.

 Do NOT use direct cz-cli subcommands when an active LLM is available. Always delegate the full request to `cz-cli agent run`.
 
+The output includes a `session_id`. Use it to inspect the run:
+- `cz-cli agent session status <session_id>` — current state (`busy`/`retry` with `progress`, `idle` with `result`, or `error`)
+- `cz-cli agent export <session_id>` — full conversation (messages, tool calls, reasoning, text). Wait until `status` is `idle` before exporting; otherwise the conversation may still be in progress.
+
 **Step 3 — ONLY if no active LLM (kind: "none" or empty list), fall back to direct commands:**
 
 Decompose the request into concrete `cz-cli` subcommands (`sql`, `schema`, `table`, `task`, `runs`, `job`, `datasource`, `profile`, etc.), execute them, and synthesize the result.

Append a synthetic <system-reminder> on each user message exposing the
active profile resolved from CZ_PROFILE / profiles.toml so the agent

-### Rule 2.1 — MUST consult lakehouse-doc skill for SQL commands
-
-When the user request involves any of the following, **MUST** consult **lakehouse-doc** skill references before answering or generating SQL:
-
-- Writing, modifying, or optimizing SQL statements (DDL / DML / DQL)
-- Asking about ClickZetta Lakehouse SQL dialect syntax, keywords, or function usage
-- Using data types, type casting, or datetime formats
-- Creating or altering tables, views, materialized views, dynamic tables, external tables
-- Data import/export (COPY INTO, PUT/GET, BulkLoad, Pipe)
-- Access control (GRANT / REVOKE), roles, permissions
-- VCluster configuration and management
-- Index creation and usage (inverted index, BloomFilter, vector index)
-- AI functions, vector search, semantic views
-- Information Schema system view queries
-
-**Rationale**: ClickZetta Lakehouse SQL dialect differs from standard SQL and other databases. Relying on general knowledge may produce incorrect syntax. Consulting lakehouse-doc significantly improves answer accuracy and confidence.
-
 ### Rule 3 — Development ends at save; execution requires separate authorization
 
 When the user says "develop", "write", "create", or "modify" a task, the work is **complete once the script is saved successfully**.

-    print(f"\n🔍 验证结果...")
-    verify_data()
-    
-    print(f"\n🎉 任务完成！")
-```
-
-#### 步骤3：配置调度信息进行周期调度（可选）
-
-若需要定期从表中拉取数据，可直接配置该python任务的调度信息。
-
-例如：若需要每天早上8点定时拉取最新数据，则可进行如下配置
-
-1. 调度周期：每天调度
-2. 调度频率：执行一次、开始调度时间：08:00
-3. 生效日期：2025-06-11（希望任务开始运行的时间）
-
-![](.topwrite/assets/702bc8f656/0aabbf094597aaef2e4fcda3bb5a5f4cda9e35c8.png =300)
-
-### 方式二：使用离线任务的方式导入飞书数据
-
-当前离线任务的方式暂时不支持周期性抽取数据，只支持手动触发执行。
-
-#### 步骤1：获取tenant\_access\_token
-
-可使用python脚本获取**tenant\_access\_token**
-
-1. 登录云器Lakehouse控制台
-2. 进入"开发" → "Python任务"
-3. 点击"新建任务"
-
-配置任务信息：
-
-**任务名称**：获取飞书tenant_access_token
-
-```
-import requests  # 添加导入语句
-
-def get_feishu_token():
-    url = "https://open.feishu.cn/open-apis/auth/v3/tenant_access_token/internal"
-    data = {
-        "app_id": "cli_xxxxxxx",
-        "app_secret": "xxxxxxxxxxxxxx"
-    }
-    response = requests.post(url, json=data)
-    
-    # 添加错误处理（重要！）
-    if response.status_code != 200:
-        raise Exception(f"HTTP请求失败，状态码: {response.status_code}")
-    
-    json_data = response.json()
-    
-    # 检查飞书API返回的错误
-    if json_data.get("code") != 0:
-        raise Exception(f"飞书API错误: [{json_data.get('code')}] {json_data.get('msg')}")
-    
-    return json_data['tenant_access_token']
-
-# 调用函数并打印结果
-try:
-    result = get_feishu_token()
-    print(f"获取的租户访问令牌: {result}")
-except Exception as e:
-    print(f"获取token失败: {str(e)}")
-```
-

-#### 步骤4：数据处理，将导入string字段处理成标准化表
-
-1. 前提：需要用户提前明确表结构。
-2. 登录云器Lakehouse控制台
-3. 进入"开发" → "SQL任务"
-4. 点击"新建任务"
-
-```
--- 1. 创建目标表
-CREATE TABLE if not EXISTS test02_feishu_parsed (
-    name STRING,
-    id BIGINT
-);
-
--- 2. 转换并插入数据
-INSERT INTO test02_feishu_parsed
-WITH parsed AS (
-    SELECT from_json(content, 'array<array<string>>') as arr
-    FROM test02_feishu
-    WHERE content IS NOT NULL
-),
-flattened AS (
-    SELECT explode(slice(arr, 2, size(arr))) as row_data
-    FROM parsed
-    WHERE size(arr) > 1
-)
-SELECT 
-    row_data[0] as name,
-    CAST(row_data[1] AS BIGINT) as id
-FROM flattened;
-
--- 3. 查看结果
-SELECT * FROM test02_feishu_parsed;
-```
-
-## 4. **常见问题**
-
-### 问题1：使用python脚本和离线任务导入飞书数据的区别
-
-Python脚本导入：可支持定期调度飞书表格中的数据，但是需要用户熟悉Python语法。
-
-离线任务导入：提供无代码页面配置，操作门槛较低。但是当前暂不支持周期调度，后续版本会支持。
-
-### 问题2：开发过程中总是提示没有权限
-
-检查相关权限是否配置正确
-
-飞书应用中：是否是基于文件类型配置相应的权限。注意，url中sheet和wiki对应的权限都是有区别的，一定要选择正确的权限点。
-
-配置后是否发布审批：用户在配置权限后，还需点击发布，待管理员审批通过后才能获取权限点
-
-是否在飞书文档中为该应用配置了访问权限。此步骤非常重要！企业用户必须完成此配置才能通过API进行访问。

-# 如何上传json/jsonl文件导入到lakehouse的表中
-
-^
-
-## 前提条件
-
-当前仅支持以下标准格式的json/jsonl文件，若不符合规范则无法成功识别
-
-**JSONL格式**
-
-> * 每行一个完整的JSON对象
-> * 行之间用换行符（\n）分隔
-> * 不允许行尾有逗号
-> * 每行必须是有效的JSON
-> * 支持标准格式化的JSON行
->   -----示例1---
->   {"id": 1, "name": "Alice", "age": 30, "city": "New York"}{"id": 2, "name": "Bob", "age": 28, "city": "Los Angeles"}{"id": 3, "name": "Charlie", "age": 35, "city": "Chicago"}{"id": 4, "name": "Diana", "age": 32, "city": "Houston"}
->   -----示例2---
->   {"id": 1, "name": "Alice", "age": 30, "city": "New York"}
->   {
->   "id": 2,
->   "name": "Bob",
->   "age": 28,
->   "city": "Los Angeles"
->   }
-
-**JSON格式**
-
-> --JSON数组格式---
-> [{"id": 1, "name": "Alice", "age": 30, "city": "New York"},{"id": 2, "name": "Bob", "age": 28, "city": "Los Angeles"},{"id": 3, "name": "Charlie", "age": 35, "city": "Chicago"},{"id": 4, "name": "Diana", "age": 32, "city": "Houston"}]
-> --JSON格式化---
-> {
-> "id": 2,
-> "name": "Bob",
-> "age": 28,
-> "city": "Los Angeles"
-> }
-
-## 方案一：使用云器lakehouse web端上传功能导入
-
-**操作步骤**：
-
-在如下地方均可以点击「上传数据」
-
-* 实例首页->数据上传
-* 开发->数据树左侧
-* 数据资产地图->数据上传
-* 数据资产地图->数据管理->数据树->数据上传
-
-将符合标准格式规范的，且后缀是json/jsonl的文件拖拽/添加至上传区域，同时选择具体的配置信息，详细操作可见 [数据上传](<upload_data.md>)
-
-
-**上传到新表**
-
-| ![](.topwrite/assets/774c65e217/dcc4141809b8624f9869df74f16143d62d0c4618.jpeg =290) | ![](.topwrite/assets/774c65e217/620b74b85135aaf3f07902fc33d9fa1c6ce62ae0.jpeg =475) |
-| ----------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------- |
-
-当文件添加后，系统会给予json/jsonl的规则解析文件中的信息，并生成相应的字段名称、类型、以及具体的数值。
-
-当确定解析的信息准确无误后，可自定义勾选本次希望上传和导入的数据。
-
-点击确定后，系统会自动创建相应的表，同时将json文件的数据导入到该表中。
-
-**上传到已有表**
-
-| ![](.topwrite/assets/774c65e217/cd685005810b036910d46bd65780b5426676360e.png =259) | ![](.topwrite/assets/774c65e217/96a4ea3793bc69dedc0d9156a20b0d3a90df6167.jpeg =391) |
-| ---------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------- |
-
-* 选择目标表后，点击下一步，会列出目标表的具体字段。
-* 请确保目标文件中的数据有相应的字段信息，若存在字段和文件中字段不一致的场景，处理规则如下：
-* 若文件中没有目标表的字段，则该字段的数值默认为null
-* 若文件中有的字段没有在表中出现，则该字段默认不进行任何处理。
-* 若文件中的字段与表中的字段名一致，但是类型不一致，则该数值会被判定为错误数据。
-
-## 方案二：使用外部volume导入
-
-> 只支持每行是一个完整的JSON对象的形式导入，若文件中存在换行、格式化的场景，则无法解析。
-
-第一步：创建外部volume的链接
-
-```Plain
-```Plain
-CREATE STORAGE CONNECTION IF NOT EXISTS oss_test3   
-     TYPE oss    
-     ENDPOINT = '对应的endpoint'  
-     ACCESS_ID = '您的access_id'   
-     ACCESS_KEY = '您的access_key'   
-     COMMENTS = 'OSS public endpoint' ; 
-```
-
-第二步：创建外部volume
-
-```SQL
-CREATE EXTERNAL VOLUME  if not exists my_volume 
-LOCATION 'oss://json_file/' 
-USING CONNECTION oss_test3
-DIRECTORY = (enable=true, auto_refresh=true)
-RECURSIVE=true;
-```
-
-第三步：校验volume是否创建成功（可选）
-
-```Plain
-list VOLUME my_volume;
-```
-
-第四步：使用 sqlline 工具或 数据库管理工具。该命令暂不支持在 Studio 中运行。
-
-```Plain
-PUT '/Users/xxx/xxxx.json'  to  volume public.my_volume  file  'ods.json';
-```
-
-第五步：查询上传的json文件格式（可选）
-
-```Plain
-SELECT * FROM VOLUME my_volume  USING  json FILES('odst.json') LIMIT 5;
-```
-
-第六步：基于文件解析后的字段创建相应的lakehouse table（table创建过程略）并将数据导入到table中
-
-```Plain
-COPY INTO day_report_simple
-FROM VOLUME my_volume
-USING JSON
-FILES('ods.json');
-```
-
-QA
-
-问题一：使用数据上传功能上传的数据解析的字段不全
-
-使用数据上传功能默认只解析json中前1000行的字段信息，若1000行外的数据中有不同的key和value默认不会进行处理。
-
-问题二：为什么创建了CONNECTION和VOLUME但是依旧提示上传文件失败？
-
-当前在云器studio产品内，无法通过运行结果直接判断CONNECTION和VOLUME是否成功创建，建议参考方案二中的第三步判断是否创建成功。

-## AI\_COMPLETE
-
-`AI_COMPLETE` 是云器 Lakehouse 平台中用于生成式 AI 任务的核心标量函数。它允许用户在 SQL 环境中直接调用大规模语言模型（LLM），根据文本提示或多模态输入生成响应（补全），从而完成文本补全、翻译、情感分析、代码生成及复杂推理等任务。
-
-云器将 AI 计算下沉至存储层与执行引擎，确保数据在平台内部即可实现智能化处理，无需流转至外部环境，从而在保障数据安全的同时极大地降低了任务延迟。
-
-用户可以提供以下类型的输入：
-
-* **文本提示**：提供一个字符串形式的 Prompt，由模型生成响应。详见 AI\_COMPLETE（单字符串）。
-* **单张图像与文本提示**：提供一张图像和一个文本提示，由模型根据图像与提示生成响应。详见 AI\_COMPLETE（单图像）。
-
-### 语法
-
-该函数的语法取决于用户提供的输入类型：
-
-* AI\_COMPLETE（单字符串）
-* AI\_COMPLETE（单图像）
-
-## AI\_COMPLETE（单字符串）
-
-使用支持的语言模型，根据文本提示生成响应（补全）。
-
-### 语法
-
-sql
-
-```sql
-AI_COMPLETE(<model>,<prompt> [,<model_parameters>][,<response_format>][,<show_details>])
-```
-
-该函数包含 **2 个必需参数**和 **3 个可选参数**，支持位置参数语法和命名参数语法。
-
-### 参数说明
-
-**必需参数**
-
-\`\`（STRING）
-
-指定要调用的语言模型。模型的来源有两种：[模型管理](AI_Gateway.md) 中的**Endpoint** 和 **API Connection 连接对象**。在函数的第一个参数中，通过不同的前缀来区分模型来源。
-
-**来源一**：模型管理中的 Endpoint：
-
-模型管理是云器 Lakehouse 平台统一管理模型服务的网关层。在 API Gateway 中注册的模型可直接通过 `endpoint:` 前缀引用。
-
-**语法格式**：
-
-```scheme
-'endpoint:<endpoint名称>'
-```
-
-**使用示例**：
-
-```sql
-SELECT AI_COMPLETE('endpoint:lis_openai_llm','prompt string',GET_PRESIGNED_URL(VOLUME volume_name, '<relative_file_path>', <expiration_time>));
-```
-
-其中，`lis_openai_llm` 模型管理 endpoint 是由平台管理员在 API Gateway 中预先配置，包含模型供应商、模型版本、认证凭据等信息。普通用户无需关心底层连接细节，只需通过端点名称即可调用对应模型。
-
-***
-
-**来源二**：API Connection 连接对象
-
-API Connection 是用户在 Lakehouse 中自行创建的模型服务连接对象，适用于需要自定义模型服务地址、认证密钥或对接私有化部署模型的场景。通过 `CREATE API CONNECTION` 语句创建连接对象后，即可在 `AI_COMPLETE` 中引用。
-
-**创建连接对象语法**：
-
-sql
-
-```sql
-CREATE API CONNECTION <connection_name>
-    TYPE ai_function
-    PROVIDER = '<provider_name>'
-    BASE_URL = '<service_endpoint_url>'
-    API_KEY = '<your_api_key>';
-```
-
-**创建连接对象示例**：
-
-```sql
-CREATE API CONNECTION conn_bailian
-    TYPE ai_function
-    PROVIDER = 'bailian'
-    BASE_URL = 'https://dashscope.aliyuncs.com/api/v1'
-    API_KEY = 'sk-xxxxxxxxxxxxxxxxxxxxxxxx';
-```
-
-其中各字段含义如下：
-
-`connection_name` 为连接对象的自定义名称，后续在 `AI_COMPLETE` 中通过该名称引用；
-
-`TYPE` 固定为 `ai_function`，表示该连接用于 AI 函数调用；
-
-`PROVIDER` 指定模型供应商标识，如 `'bailian'`（百炼）、`'openai'`、`'anthropic'` 等；
-
-`BASE_URL` 为模型服务的 API 基础地址；`API_KEY` 为调用该服务所需的认证密钥。
-
-***
-
-**在 AI\_COMPLETE 中引用连接对象**：
-
-```sql
-SELECT AI_COMPLETE('connection:conn_bailian','请简要介绍量子计算的基本原理。');
-```
-
-**语法格式**：
-
-```scheme
-'connection:<连接对象名称>'
-```
-
-###
-
-### 示例
-
-**基础用法：单个文本提示**
-
-```
-SELECT AI_COMPLETE(
-    'endpoint:aliyun-qwen3max',
-    '中国的首都在哪里?'
-);
-
-```
-
-**图像识别**：
-
-使用支持的多模态语言模型，根据单张图像与文本提示生成响应（补全）。该模式适用于视觉问答（VQA）、图像内容描述、图像信息提取、OCR 识别等需要模型理解图像内容的场景。
-
-```
-SELECT 
-        a.id, 
-        a.question,
-        a.answer AS standard_answer,
-        -- 1. AI生成答案
-        ai_complete(
-            'endpoint:doubao-seed-2-0-pro-260215',
-            JSON_OBJECT(
-                'system', 'You are a VQA assistant. Answer based on the image in English. Be extremely concise (1-5 words).',
-                'user', a.question,
-                'images', ARRAY(CONCAT('volume://volumes/datagpt_ws/image_hub/my_images/', LPAD(CAST(a.id AS STRING), 11, '0'), '.jpg'))
-            )
-        ) AS ai_generated_answer,
-        -- 2. 生成图片预览URL
-        get_presigned_url(
-            VOLUME lakehouse_ai.image_hub.my_images,
-            LPAD(CAST(a.id AS STRING), 11, '0') || '.jpg',
-            7200  
-        ) AS image_preview_url,
-        -- 3. 图片存储路径
-        CONCAT('volume://volumes/lakehouse_ai/image_hub/my_images/', LPAD(CAST(a.id AS STRING), 11, '0'), '.jpg') AS image_path
-    FROM 
-        lakehouse_ai.image_hub.evjvqa_annotations_20 AS a
-```
-
-效果如下：

-## AI\_EMBEDDING
-
-使用支持的嵌入模型（Embedding Model）将文本转换为高维向量表示。生成的向量可用于语义搜索、文本相似度计算、聚类分析、推荐系统等下游任务。
-
-### 语法
-
-```sql
-AI_EMBEDDING(<model>, <input> [ , <model_parameters> ])
-```
-
-该函数包含 **2 个必需参数**和 **1 个可选参数**，支持位置参数语法和命名参数语法。
-
-### 参数说明
-
-**必需参数**
-
-**`model`**
-
-指定要调用的嵌入模型。与 `AI_COMPLETE` 一致，模型来源分为两种：API Gateway 端点和 API Connection 连接对象。
-
-通过 API Gateway 端点调用时，使用 `endpoint` 前缀加端点名称的格式：
-
-```scheme
-'endpoint:<端点名称>'
-```
-
-通过 API Connection 连接对象调用时，需先通过 `CREATE API CONNECTION` 创建连接，再使用 `connection/` 前缀引用：
-
-```scheme
-'connection:<连接对象名称>'
-```
-
-> **说明**： 请确保所指定的模型为嵌入模型（Embedding Model），而非对话补全模型。嵌入模型专门用于将文本映射为固定维度的数值向量，常见的嵌入模型包括 OpenAI 的 `text-embedding-3-small`、`text-embedding-3-large`，阿里云百炼的 `text-embedding-v4` 等。
-
-**`\`**（STRING）
-
-需要转换为向量的输入文本。可以是单个词语、一个句子、一段文字，也可以是来自数据表中某个字段的值。输入文本的最大长度受所选模型的上下文窗口限制，超出限制可能导致文本被截断或调用失败。
-
-**可选参数**
-
-**`\`**（OBJECT）
-
-以 JSON 对象形式传入的模型超参数，用于控制嵌入模型的行为。不同模型支持的参数可能有所不同，常见参数如下：
-
-| 参数                    | 类型     | 说明                                                                                                                      |
-| --------------------- | ------ | ----------------------------------------------------------------------------------------------------------------------- |
-| `input`               | STRING | 指定输入内容的类型。常见取值为 `'text'`（普通文本）和 `'query'`（查询文本）。部分模型会根据输入类型对向量做针对性优化，例如在检索场景中，文档内容使用 `'text'`，用户查询使用 `'query'`，可提升检索精度。 |
-| `embedding.dimension` | STRING | 指定输出向量的维度。较高的维度通常能保留更丰富的语义信息，但会占用更多存储空间和计算资源。常见取值包括 `'256'`、`'512'`、`'1024'`、`'1536'` 等，具体支持的维度范围取决于所选模型。               |

-   * 趋势图表：折线图展示指标变化（如成功率骤降需排查模型连通性）；
-   * 错误明细：点击「错误率」可查看错误类型（如限流、权限不足）；
-
-### 3.2 API KEY 管理（安全访问凭证）
-
-**业务价值**：API KEY 是模型外部调用的唯一凭证，严格管理可防止资源滥用与数据泄露。
-**操作步骤（仅 Gateway Admin）**：
-
-1. 进入「模型管理 → API KEY」页面；
-2. 新建 API KEY：
-   * 点击「新建 KEY」→ 输入名称（需关联业务场景，如 “ecommerce-recommend-key”）；
-   * 点击「确认」，系统生成 KEY；
-3. 日常管理：
-   * 禁用/启用：点击「禁用」（禁用后无法调用，适用于临时停用），需用时点击「启用」；
-   * 删除：需先停用关联调用（如 SQL/OpenAPI 调用），点击「删除」→ 确认（KEY 立即失效）；
-   * 筛选：通过「状态（正常 / 禁用）」「负责人」快速定位目标 KEY；
-4. 安全注意事项：
-   * 避免明文存储（如代码仓库、配置文件）；
-   * 定期轮换（建议每 3 个月）；
-   * 泄露后需立即删除并新建，更新所有关联调用配置；
-     \</.topwrite/assets/image (5).png>)
-
-### 3.3 权限管理（精细化资源控制）
-
-#### 3.3.1 Gateway Admin 管理（全局权限管控）
-
-**业务价值**：确保企业有且仅有授权人员负责全局配置，避免权限混乱。
-**操作步骤（仅当前 Gateway Admin）**：
-
-1. 进入「模型管理 → 权限 → Gateway 管理员」；
-2. 添加管理员：
-   * 点击「添加」→ 勾选目标用户（需在租户内已注册）；

-4. 查看记录：页面展示所有 Admin 的「用户名、添加时间、操作人」；
-   \</.topwrite/assets/image (6).png>)
-
-#### 3.3.2 Endpoint 权限管理（业务线权限隔离）
-
-**业务价值**：按业务线分配 Endpoint 权限，避免跨业务资源滥用（如电商 Endpoint 仅电商团队可调用）。
-**操作步骤（仅 Endpoint Admin）**：
-
-1. 进入「模型管理 → 权限 → Endpoint 权限」；
-2. 授权操作：
-   * 点击「添加」→ 选择目标用户 → 勾选权限类型（参考 2.2 角色权限）；
-   * 选择需授权的 Endpoint（可多选）；
-   * 点击「确认」，用户获得对应权限；
-3. 收回权限：
-   * 在「已授权列表」找到目标用户与 Endpoint；
-   * 点击「移除」→ 确认，权限立即失效；
-     \</.topwrite/assets/image (7).png>)
-
-### 3.4 配额与用量管理（成本控制）
-
-#### 3.4.1 租户配额配置（企业级预算管控）
-
-**业务价值**：设置企业月度 Token 总上限，避免超预算（如每月 500 万 Token，覆盖全业务线）。
-**操作步骤（仅 Gateway Admin）**：
-
-1. 进入「模型管理 → 用量 → 租户配额」；
-2. 首次配置：
-   * 若为空态（提示 “当前租户尚未设置配额”），点击「设置租户配额」；
-   * 填写配置：粒度默认「租户级别」、周期默认「每月」、Token 配额（如 5000000，即 500 万 / 月）；
-   * 点击「保存」，跳转至配额页查看「总配额、已用量、剩余量、每日用量趋势」；
-3. 调整配额：点击「编辑配额」→ 修改数值 → 保存（实时生效）；
-   \</.topwrite/assets/image (8).png>)
-
-#### 3.4.2 Endpoint 配额配置（业务线预算分配）
-
-**业务价值**：为单个 Endpoint 分配独立配额（如电商推荐模型每月 100 万 Token），实现业务线成本隔离。
-**操作步骤（Gateway Admin/Endpoint Admin）**：
-
-1. 进入「模型管理 → Endpoint」，选择目标 Endpoint，点击「编辑」；
-2. 找到「AI Gateway → 访问配额」模块；
-3. 填写配置：粒度默认「Endpoint 级别」、周期「每月」、Token 配额（如 1000000）；
-4. 关键规则：实际可用配额 = 租户配额与 Endpoint 配额的较小值（如租户剩 50 万，Endpoint 配额 100 万，实际可用 50 万）；
-5. 点击「保存」，在 Endpoint 详情页查看配额使用情况；
-   \</.topwrite/assets/image (9).png>)
-
-#### 3.4.3 用量统计查询（多维度成本归因）
-
-**业务价值**：按 Endpoint / 用户 / API KEY 维度查询用量，定位高成本资源（如某用户调用量异常）。
-**操作步骤（角色权限差异）**：
-
-1. 进入「模型管理 → 用量 → 用量统计」；
-2. 配置查询条件：
-   * 时间范围：默认近 1 月，支持切换「近 1 周 / 自定义」；
-   * 统计维度：
-     * 普通用户：仅查看「自身关联的 Endpoint / 用户」；
-     * Gateway Admin：查看「Endpoint / 用户 / API KEY / 账户 / 账号明细」；
-3. 查看数据：
-   * 列表视图：展示「统计维度、日期、调用次数、输入 Token、输出 Token、总用量」；
-   * 图表视图：点击「切换图表」，通过折线图 / 柱状图查看用量趋势；
-4. 下载明细（仅 Gateway Admin）：
-   * 点击「下载明细」→ 选择年月（支持最近 1 年）→ 确认；
-     \</.topwrite/assets/image (10).png>)
-
-### 3.5 多场景模型调用（适配不同用户需求）
-
-#### 3.5.1 SQL 调用（数据分析师 / 开发工程师）
-
-**业务价值**：直接在 SQL 中调用模型，实现 “数据查询 + AI 分析” 一体化（如订单文本嵌入、用户评论情感分析）。
-您可以在SQL中直接调用，例如：
-
-```Plain
-select ai_complete('endpoint\:lis\_aliyun\_qwen\_max','中国首都是哪里？')
-```
-
-#### 3.5.2 DataGPT 调用（所有角色操作）
-
-DataGPT 通过标准化接口实现 AI 模型调用，可快速完成模型对接与替换。您只需在 DataGPT 的模型配置界面，将我方提供的专属调用地址（Base URL）与访问凭证（API Key），替换平台现有模型配置，即可完成模型调用链路的切换，依托 AI Gateway 实现稳定、可管控的 AI 能力调用。
-
-#### 3.5.3 OpenAPI 标准调用（开发场景）
-
-* 调用地址：Endpoint 列表中的 “访问地址”；
-* API KEY：从「API KEY 管理」中获取（仅 Gateway Admin 可创建）；
-* 调用方式：
-  * 进入「模型管理 → Endpoint」页面，点击 Endpoint 名称，进入详情页；
-  * 在详情页的下方，「Endpoint 调用示例」部分，为您展示 OpenAI-python 和 REST API-cURL 两种调用方式的示例。
-
-## 四、关键注意事项
-
-1. **权限控制**：操作前确认自身角色权限（如普通用户不可删除 Endpoint），避免因权限不足导致操作失败；如需扩展权限，联系对应 Admin（Gateway Admin 负责全局权限，Endpoint Admin 负责业务线权限）。
-
-2. **数据留存**：
-   * 账号明细数据：仅保留最近 1 年，需长期存储需每月下载备份（Gateway Admin 操作）；
-   * 用量监控数据：最多保留 60 天，关键指标（如月度配额使用情况）需定期截图存档。
-
-3. **模型删除风险**：
-   * Endpoint 删除后不可恢复，删除前需：① 停用所有关联调用（SQL/OpenAPI/DataGPT）；② 通知所有有权限用户；
-   * 内置托管模型删除后，需重新使用时联系技术支持（不可自行恢复）。
-
-4. **API KEY 安全**：
-   * 避免泄露（如明文分享、存储在代码仓库）；
-   * 定期轮换（建议每 3 个月）；
-   * 泄露后需立即在「API KEY 管理」中删除并重新创建，更新所有关联配置。
-
-5. **配额生效规则**：Endpoint 实际可用配额 = 租户配额与 Endpoint 配额的较小值，设置时避免 Endpoint 配额远超租户配额（如租户每月 100 万，Endpoint 设 200 万，实际仅 100 万可用，造成配置浪费）。
-
-6. **兼容性注意**：外部模型需符合 OpenAI 接口规范，否则无法接入（如不支持 “messages” 参数的模型需厂商适配）；编辑模型版本时，需确认下游调用系统是否支持新版本（避免兼容性问题）。

-# AI 函数
-
-## 概述
-
-在云器 Lakehouse 中，AI 函数的实现**依托于**外部函数（External Function）的框架。外部函数（亦称远程函数，Remote Function）是一种特殊的自定义函数（UDF），它允许用户通过 Python 或 Java 语言定义函数逻辑，但其核心计算任务会被\*\*卸载（offload）\*\*到外部的远程服务执行（支持的远程服务包括：阿里云的函数计算 FC、腾讯云的云函数 SCF）。在执行过程中可调用：
-
-* **在线服务**：以 API 形式对外提供的在线服务，如 AI 在线模型服务（例如大语言模型 API、云平台提供的在线 AI API 服务）。
-* **离线功能**：将特定功能函数代码、依赖库、模型和数据等文件打包成的离线服务包，如从 Hugging Face 下载的图像识别模型等。
-
-云器 Lakehouse 通过创建 API Connection，在元数据中保存外部函数计算服务的连接和访问信息。外部函数通过 HTTP 协议调用外部函数计算服务，实现数据处理并返回结果。
-![](.topwrite/assets/a7546df1-be39-41e9-9c80-e0e90ce3d353.svg)
-Lakehouse 平台在获得用户预先授权后，于创建外部函数时，将自动在客户账号下的函数计算服务中部署该函数。当用户在 SQL 查询中使用外部函数时，由外部函数实现与外部计算服务的安全连接、数据处理并返回查询结果。

-
-## 修改 Schema 属性
-
-除了修改注释，还可以为 schema 设置或更新属性。使用以下语法：
-
-```SQL
-ALTER SCHEMA schema_name SET PROPERTIES (key1 = 'value1', key2 = 'value2', ...);
-```
-
-### 示例
-
-1. 为 `rc4_l` schema 设置属性 `custom_property` 为 `true`：
-
-   ```SQL
-   ALTER SCHEMA rc4_l SET PROPERTIES (custom_property = 'true');
-   ```
-
-   查看 schema 属性是否设置成功：
-
-   ```SQL
-   DESC SCHEMA rc4_l;
-   ```
-
-   预期输出结果中的 properties 部分应包含新设置的属性：
-
-   ```
-   +--------------------+-------------------------+
-   |     info_name      |       info_value        |
-   +--------------------+-------------------------+
-   | ...                 | ...                      |
-   | properties          | {custom_property='true'} |
-   +--------------------+-------------------------+
-   ```
-
-## 权限要求
-
-执行 `ALTER SCHEMA` 语句的用户必须拥有对应 schema 的 ALTER 权限。如果没有相应权限，操作将被拒绝。

-# 功能描述
-
-本功能允许用户通过 ALTER 语句对表中的列进行修改，包括添加列、修改列、删除列以及重命名列。同时支持复杂类型的变化，如 struct、array 和 map 等。
-
-# 添加字段
-
-## 语法
-
-```sql
--- 添加列
-ALTER TABLE table_name ADD COLUMN
-      column1_name_identifier data_type [COMMENT comment]
-      [FIRST | AFTER column1_name_identifier | BEFORE column1_name_identifier ]  ,....
-
-column_name_identifier :==
-    -- 普通字段
-    column_name
-    -- 复杂类型struct表示方法
-    -- struct类型struct,<x: double, y: double>
-    column_name.struct_column_name  
-    -- array类型嵌套struct表示方法
-    -- 添加字段,array<struct<x: double, y: double>>
-    column_name.ELEMENT.struct_column_name
-    --map类型嵌套struct表示方法
-    --map key 添加字段
-    column_name.KEY.struct_column_name 
-    --map value添加字段
-    column_name.VALUE.struct_column_name    
-```
-
-## 参数说明
-
-* **column_name_identifier**：字段标识符，用于指定添加、删除或重命名的字段名。
-* **FIRST | AFTER column_name_identifier**：指定字段添加的位置，可以添加到字段之前或之后。
-
-## 使用示例
-
-1. 添加普通字段：
-
-   ```sql
-   ALTER TABLE my_table ADD COLUMN new_column INT;
-   ```
-
-2. 添加复杂类型字段：
-
-   ```sql
-   CREATE TABLE my_complex_table (
-       point STRUCT<x: INT, y: DOUBLE>,
-       points ARRAY<STRUCT<x: DOUBLE, y: DOUBLE>>,
-       points_map MAP<STRUCT<x: INT>, STRUCT<a: INT>>
-   );
-
-   -- 在struct中添加字段
-   ALTER TABLE my_complex_table ADD COLUMN point.z DOUBLE;
-
-   --map value中struct添加字段
-   ALTER TABLE my_complex_table ADD COLUMN points_map.value.b INT;
-
-   --map key中struct添加字段
-   ALTER TABLE my_complex_table ADD COLUMN points_map.key.y INT;
-
-   --array中struct添加字段
-   ALTER TABLE my_complex_table ADD COLUMN points.element.z DOUBLE;
-   --添加多个字段同时指定位置
-    CREATE TABLE test (a string);
-    ALTER TABLE test  ADD COLUMN b string, c string, CHANGE COLUMN a AFTER c;
-
-   ```
-
-# 删除字段
-
-## 语法
-
-```sql
-ALTER TABLE table_name DROP COLUMN column_name_identifier [, column_name_identifier ... ]
-```
-
-## 使用示例
-
-1. 删除普通字段：
-
-   ```sql
-   ALTER TABLE my_table DROP COLUMN old_column;
-   ```
-
-2. 删除复杂类型字段：
-
-   ```sql
-   ALTER TABLE my_complex_table DROP COLUMN point.z;
-   ALTER TABLE my_complex_table DROP COLUMN points.element.y;
-   ALTER TABLE my_complex_table DROP COLUMN points_map.key.x;
-   ```
-
-# 重命名字段
-
-## 语法
-
-```sql
-ALTER TABLE table_name RENAME COLUMN column_name_identifier TO new_column_name_identifier;
-```
-
-## 使用示例
-
-1. 重命名普通字段：
-
-   ```sql
-   ALTER TABLE my_table RENAME COLUMN old_name TO new_name;
-   ```
-
-2. 重命名复杂类型字段：
-
-   ```sql
-   ALTER TABLE my_complex_table RENAME COLUMN point.x TO xx;
-   ALTER TABLE my_complex_table RENAME COLUMN points.element.x TO xx;
-   ALTER TABLE my_complex_table RENAME COLUMN points_map.key.x TO xx;
-   ```
-
-# 修改字段
-
-## 语法
-
-```sql
--- 修改字段位置
-ALTER TABLE table_name CHANGE COLUMN column_name_identifier { FIRST | AFTER column_identifier }
-
--- 修改字段类型
-ALTER TABLE table_name CHANGE COLUMN column_name_identifier TYPE data_type
-
--- 修改字段注释
-ALTER TABLE table_name CHANGE COLUMN column_name_identifier COMMENT 'comment'
-```
-
-DECIMAL 类型转换**只支持精度（整数位）和小数位同时增大**的场景。
-
-**DECIMAL 类型的两个参数**
-
-```
-DECIMAL(P, S)  ├─ P（Precision）：总位数（整数位 + 小数位）  └─ S（Scale）：小数位数
-```
-
-例如：`DECIMAL(10, 2)` 表示
-
-* 总共 10 位数字
-* 其中 2 位是小数位
-
-**场景 1：两个参数都增大**
-
-```sql
--- 源表定义
-CREATE TABLE test_alter(a DECIMAL(10,2));
--- ✅ 正确：整数位和小数位都增大
-ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(12,2);
--- 说明：从 10 位增加到 12 位，小数位不变
-ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(13,3);
--- 说明：从 10 位增加到 13 位，小数位从 2 增加到 3
-```
-
-**场景 2：只增大整数位，小数位不变**
-
-```sql
-ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(15,2);
--- 从 DECIMAL(10,2) 转为 DECIMAL(15,2)
--- 整数位：从 8 位（10-2）增加到 13 位（15-2）
-```
-
-**场景 3：同时增大整数位和小数位**
-
-```sql
-ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(20,5);
--- 从 DECIMAL(10,2) 转为 DECIMAL(20,5)
--- 整数位增大，小数位也增大
--- 这是最安全的转换方式
-```
-
-❌ 错误的类型转换
-
-**错误 1：整数位不变，只增大小数位**
-
-```sql
--- ❌ 错误
-ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(10,3);
--- 原因：总位数不变，只是改变了小数位比例
--- 结果：系统会报错或数据可能丢失
-```
-
-**错误 2：减少任一参数**
-
-```sql
--- ❌ 错误：减少总位数
-ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(8,2);
--- ❌ 错误：减少小数位
-ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(12,1);
--- ❌ 错误：两个都减少
-ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(8,1);
-```
-
-**错误 3：只增大小数位**
-
-```sql
--- ❌ 错误
-ALTER TABLE test_alter CHANGE COLUMN a TYPE DECIMAL(10,3);
--- 问题：总位数从 10 不变为 10，但小数位从 2 增加到 3
--- 结果：整数位从 8 减少到 7，可能导致数据溢出或精度丢失
-```

-# ARRAY
-`ARRAY`是一种数据类型，用于表示由同一种类型的元素序列构成的值。这种数据类型可以存储一系列具有相同数据类型的元素，方便进行统一管理和操作。
-
-## 语法
-
-```sql
-ARRAY <elementType>
-```
-- `elementType`：指定数组中元素的数据类型。
-
-## ARRAY常量格式
-```
-select [1,3,4];
-```
-这种格式表示一个数组常量。请确保在定义数组常量时**不使用引号**，因为引号会使其被识别为字符串类型，而字符串类型的`'[1,3,4]'`不能直接被使用 `CAST` 转化成`array<int>`类型。
-
-## 示例
-
-1. 创建一个整数数组：
-
-```sql
-SELECT ARRAY(1, 2, 3);
-```
-执行结果：
-| result    |
-| --------- |
-| [1, 2, 3] |
-
-2. 将整数数组转换为字符串数组：
-
-```sql
-SELECT CAST(ARRAY(1, 2, 3) AS ARRAY<STRING>);
-```
-执行结果：
-| result          |
-| --------------- |
-| ["1", "2", "3"] |
-
-3. 获取数组元素的数据类型：
-
-```sql
-SELECT typeof(ARRAY(1.2, 1.4, 1.8));
-```
-执行结果：
-| result              |
-| ------------------- |
-| array<decimal(2,1)> |
-
-4. 创建一个嵌套数组（数组中包含其他数组）：

-# 基于云器Lakehouse构建面向分析的Modern Data Stack
-
-本文介绍如何基于云器Lakehouse、Metabase和MindsDB构建面向分析的Modern Data Stack。
-
-
-
-## 方案架构
-
-基于云器Lakehouse的Modern Data Stack方案特点：
-
-* 实现从AWS数据仓库到数据湖的演进，通过云器Lakehouse实现湖仓一体的优化提升，大幅降低数据存储、计算和运维成本。
-* 无限存储与高效迁移：全链路数据通道采用云对象存储实现存算分离架构，避免了传统方案中服务器节点的带宽和存储容量瓶颈。
-* 云器Lakehouse + Metabase：实现极简的BI数据分析，仅需点击两次鼠标即可完成可视化数据探索和分析，极大降低业务人员分析数据的门槛，对业务人员十分友好。
-* 云器Lakehouse + MindsDB：实现100%基于SQL的AI与LLM增强分析。无需掌握其他复杂语言，数据工程师和BI分析人员基于SQL就可以实现AI和LLM的增强分析。
-* 降低数据全栈（云基础设施、数据湖、数据仓库、BI、AI）对技术人员的要求，降低企业用人门槛，提升人才可得性。
-
-本方案主打简单易用，旨在帮助企业将工作重点从数据基建转向数据分析，实现数据分析的现代化。
-
-![](.topwrite/assets/image_1734577522644.png)
-
-
-
-上图展示了迁移至并基于云器Lakehouse构建Modern Data Stack的架构，概述如下：
-
-* 使用Redshift UNLOAD命令将数据卸载到S3存储桶中的Parquet文件。
-* 通过云器Lakehouse的 `SELECT * FROM VOLUME` 语句，将AWS S3存储桶中Parquet文件的数据直接加载到云器Lakehouse的表中，实现快速数据入仓（本例中加载2000多万行的一张表，完成数据入仓仅需30秒）。
-* BI应用：通过Metabase探索和分析数据（从表格到仪表盘仅需点击两次鼠标——没错，就是两次）。
-* AI应用：通过MindsDB对房价进行预测（100%用SQL实现模型预测）。
-
-## 方案组成
-
-* AWS：
-
-  * Redshift
-  * S3
-
-* 云器
-
-  * 云器Lakehouse，多云及一体化数据平台。采用SaaS全托管服务模式，为企业提供极简数据架构。
-  * 云器Lakehouse Driver for Metabase
-  * 云器Lakehouse Connector for MindsDB
-
-* 数据分析
-
-  * Metabase with Lakehouse Driver on Docker：Metabase是一个完整的BI平台，但在设计理念上与Superset大不相同。Metabase非常注重业务人员（如产品经理、市场运营人员）的使用体验，让他们能自由地探索数据，回答自己的问题。
-  * MindsDB with Lakehouse Connector on Docker：MindsDB可直接在云器Lakehouse中进行建模，省去了数据处理、模型搭建等专业步骤。数据分析人员、BI分析师无需熟悉数据工程、建模知识，即可开箱使用，降低了建模门槛，让人人都是数据分析师，人人都会应用算法。
-  * Zeppelin with Lakehouse JDBC Interpreter on Docker
-  * Zeppelin with MySQL JDBC Interpreter on Docker（连接MindsDB的MySQL接口）
-
-## 为什么要使用云器Lakehouse？
-
-* **完全托管**： 云器Lakehouse提供完全托管、基于云的Lakehouse服务，易于使用和扩展。这意味着您不必担心管理和维护自身的硬件与基础设施，避免了耗时且昂贵的投入，实现安心托付。
-* **节省成本**：与Redshift相比，云器Lakehouse的总拥有成本（TCO）通常较低，因为它根据使用情况收费，而不需要预先承诺。云器Lakehouse高度灵活的定价模型使您只需为实际使用的资源付费，而无需被锁定在固定成本模型中。
-* **可扩展性**： 云器Lakehouse 旨在处理大量数据，并且可以根据需要扩展或缩小，这对计算负载波动明显的企业来说是一个不错的选择。云器Lakehouse数据存储在云上的对象存储服务中，在数据规模上实现“无限扩展”。
-* **性能**： 云器Lakehouse采用Single Engine All Data架构，实现计算与存储分离，使其能够比Redshift更快地处理查询。
-* **易于使用**： 云器Lakehouse提供了一体化的数据集成、开发、运维和治理平台，这使得开发和管理变得更加容易，无需复杂的方案集成。
-* **数据源支持**： 云器Lakehouse支持多种数据源和格式，包括结构化和半结构化数据，大多数情况下仅用SQL就可完成BI和AI应用的开发。
-* **数据集成**： 云器Lakehouse内置的数据集成功能支持广泛的数据源，使数据加载和准备变得更加容易，从而便于进行分析。
-  总体而言，迁移到云器Lakehouse可以帮助您节省时间和金钱，并使您能够更轻松、更有效地处理和分析数据。
-
-## 实施步骤
-
-### 数据抽取（E）
-
-#### 将房价销售数据从Redshift卸载到S3
-
-Redshift UNLOAD 命令：使用 Amazon S3 服务器端加密 (SSE-S3) 将查询结果卸载到 Amazon S3 上的一个或多个文本、JSON 或 Apache Parquet 文件。
-
-```SQL
-UNLOAD ('select-statement')
-TO 's3://object-path/name-prefix'
-authorization
-[ option, ...] 
-
-where authorization is
-IAM_ROLE { default | 'arn:aws:iam::<AWS account-id-1>:role/<role-name>[,arn:aws:iam::<AWS account-id-2>:role/<role-name>][,...]' }
-            
-where option is
-| [ FORMAT [ AS ] ] CSV | PARQUET | JSON
-| PARTITION BY ( column_name [, ... ] ) [ INCLUDE ]
-| MANIFEST [ VERBOSE ]
-| HEADER
-| DELIMITER [ AS ] 'delimiter-char'
-| FIXEDWIDTH [ AS ] 'fixedwidth-spec'
-| ENCRYPTED [ AUTO ]
-| BZIP2
-| GZIP
-| ZSTD
-| ADDQUOTES
-| NULL [ AS ] 'null-string'
-| ESCAPE
-| ALLOWOVERWRITE
-| CLEANPATH
-| PARALLEL [ { ON | TRUE } | { OFF | FALSE } ]
-| MAXFILESIZE [AS] max-size [ MB | GB ]
-| ROWGROUPSIZE [AS] size [ MB | GB ]
-| REGION [AS] 'aws-region' }
-| EXTENSION 'extension-name'
-```
-
-#### 数据湖数据探索：通过云器Lakehouse探索AWS S3上的Parquet数据
-
-查看总共有多少行数据（需要提前创建好云器Lakehouse的 `STORAGE CONNECTION` 和 `EXTERNAL VOLUME`）：
-
-![](.topwrite/assets/image_1718933981338.png)
-
-预览数据
-
-```SQL
-select 
-        *
-    from volume hz_qiliang_csv_volume(
-    price  int,
-    date  int,
-    postcode1  binary,
-    postcode2  binary,
-    type  binary,
-    is_new  int,
-    duration  binary,

-# BIGINT
-
-`BIGINT` 是一种数据类型，用于表示 8 字节的带符号整数。它的数值范围为 -9,223,372,036,854,775,808 到 9,223,372,036,854,775,807。这种类型通常用于存储非常大的整数值。
-
-## 语法
-
-```
-BIGINT [ + | - ] digit [ ... ] [L]
-```
-
-- `digit`：表示 0 到 9 的任意数字。
-- `L`：表示字面量后缀，用于指示这是一个 `BIGINT` 类型的数值。如果数值不在 `INT` 范围内，即使没有 `L` 后缀，也会自动转换为 `BIGINT` 类型。
-
-## 使用示例
-
-1. 插入一个正数 `BIGINT` 值：
-
-```
-INSERT INTO my_table (my_column) VALUES (+1L);
-```
-
-2. 插入一个负数 `BIGINT` 值：
-
-```
-INSERT INTO my_table (my_column) VALUES (-1L);
-```
-
-3. 插入一个不带 `L` 后缀的 `BIGINT` 值（如果数值在 `INT` 范围内，会隐式转换为 `INT` 类型）：
-
-```
-INSERT INTO my_table (my_column) VALUES (123456789);
-```
-
-4. 在查询中使用 `BIGINT` 类型的数值进行比较：
-
-```
-SELECT * FROM my_table WHERE my_column = 9223372036854775807;
-```
-
-5. 使用 `CAST` 函数将其他类型的数值转换为 `BIGINT`：
-
-```
-SELECT CAST(123.456 AS BIGINT);
-```
-
-## 注意事项
-
-- 当使用 `BIGINT` 类型存储数值时，请确保数值在允许的范围内，否则可能会导致溢出错误。
-- 在进行数值比较或计算时，需要注意数据类型之间的隐式转换，以免出现意外的结果。

-# 二进制类型（BINARY）
-
-## 概述
-
-在 Lakehouse 中，BINARY 类型用于存储二进制数据，适用于存储图像、音频、视频以及其他二进制文件。BINARY 类型能够确保数据的完整性和一致性，适用于各种场景。最大写入长度限制为 16 MB。批量、实时导入时会对字段进行长度校验。如果您导入的数据超过 16 MB，可以修改表的属性（Properties）来调整限制，例如将 BINARY 长度设置为 32 MB：
-```
-ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.binary.bytes"="33554432");
-```
-
-
-
-## 语法
-
-BINARY 类型的声明非常简单，只需在数据类型前加上关键字 `BINARY` 即可。例如：
-
-```sql
-CREATE TABLE binary_table (
-  id INT,
-  data BINARY
-);
-```
-
-## BINARY 常量值
-
-在 SQL 语句中，可以使用 `X` 前缀来构造 BINARY 常量值。例如：
-
-```sql
-SELECT X'4';
-```
-
-上述语句将返回一个字节序列 `[4]`。`X` 后跟的 `num` 是一个或多个十六进制字符，范围从 0 到 F，支持大写或小写。例如：
-
-```sql
-SELECT X'A413F';
-```
-
-将返回 `[0a 41 3f]`。
-
-## 转换函数
-
-Lakehouse 提供了多种函数来处理 BINARY 类型的数据，包括：
-
-1. `CAST()` 函数：将其他类型的数据转换为 BINARY 类型。
-2. `BASE64()` 函数：将二进制数据转换为 BASE64 编码的字符串。
-3. `UNBASE64()` 函数：将 BASE64 编码的字符串转换为二进制数据。
-4. `BINARY()` 函数：将字符串转换为 BINARY 类型的字节流。
-
-## 约束限制
-* BINARY 类型最大存储长度为 16 MB。
-
-## 示例
-
-以下是一些使用 BINARY 类型和相关函数的示例：
-
-1. 创建一个包含 BINARY 类型列的表：
-
-```sql
-CREATE TABLE binary_table (
-  id INT,
-  data BINARY
-);
-```
-
-2. 向表中插入数据：
-
-```sql
-INSERT INTO binary_table (id, data) VALUES (1, X'1');
-```
-
-3. 将字符串转换为 BINARY 类型并插入到表中：
-
-```sql
-INSERT INTO binary_table (id, data)
-SELECT col1, BINARY(col2)
-FROM values(1, 'guan') AS data(col1, col2);
-```
-
-4. 查询表中的数据：
-
-```sql
-SELECT data FROM binary_table;
-```
-
-5. 使用 `CAST()` 函数将字符串转换为 BINARY 类型：
-
-```sql
-SELECT CAST('ClickZetta' AS BINARY);
-```
-
-将返回 `[43 6c 69 63 6b 5a 65 74 74 61]`。
-
-6. 使用 `base64()` 和 `unbase64()` 函数进行编码和解码：
-
-```sql
-SELECT base64('ClickZetta');
-```
-
-将返回 `Q2xpY2taZXR0YQ==`，然后使用 `unbase64()` 函数进行解码：
-
-```sql
-SELECT cast(unbase64('Q2xpY2taZXR0YQ==') as string);
-```
-
-将返回原始字符串 `ClickZetta`。

-# 云器 Lakehouse 图像解析最佳实践
-
-## 引言
-
-在数据驱动的时代，图像数据已成为企业数据资产的重要组成部分。云器 Lakehouse 通过集成先进的图像识别和向量检索技术，为企业提供了一套完整的图像数据管理和分析解决方案。本文将通过一个美食图像识别的实战案例，详细介绍如何在云器 Lakehouse 中构建端到端的图像解析系统。
-
-## 1. 关键产品功能
-
-* **多模态存储**：支持图像文件、向量数据、结构化元数据的统一管理
-* **外部函数**（EXTERNAL FUNCTION）：无缝调用 AI 模型进行图像识别和向量化
-* **向量检索**：原生支持 1024 维向量存储和相似度计算
-
-## 2.实战案例：美食图像识别系统
-
-### 2.1 创建数据表结构
-
-首先，我们需要创建一个包含向量字段的表来存储图像信息：
-
-```sql
--- 创建美食图像识别数据表
-CREATE    TABLE IF NOT EXISTS dish_images (
-          id BIGINT NOT NULL PRIMARY KEY IDENTITY (1),
-          url STRING NOT NULL COMMENT '图片的原始URL地址',
-          file_name STRING NOT NULL COMMENT '图片文件名',
-          image_content STRING COMMENT '使用fc_image_to_text提取的菜品信息',
-          image_vector VECTOR (FLOAT, 1024) COMMENT '使用fc_gen_emmbeding生成的图片向量',
-          created_at TIMESTAMP DEFAULT current_timestamp() COMMENT '创建时间'
-          )
-          COMMENT '美食图片识别数据表';
-
-```
-
-### 2.2 批量上传图像到 VOLUME
-
-云器 Lakehouse 的 VOLUME 功能提供了文件管理能力。以下示例展示如何从 URL 批量下载并上传图像。您可以从下方网址下载图片到本地，再通过 [Lakehouse JDBC 客户端](connect-with-cli.md) 将文件 PUT 到 USER VOLUME 中：
-
-[图片地址](http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood1.jpg)（可通过变换结果中的数字下载更多图片）
-
-```sql
--- 注意：PUT命令需要通过 JDBC 客户端执行，不能在 SQL 编辑器中直接运行
--- 从URL批量下载并上传图像到 USER VOLUME
-PUT 
-    '/User/Downloads/RecognizeFood1.jpg',
-    '/User/Downloads/RecognizeFood2.jpg',
-    '/User/Downloads/RecognizeFood3.jpg' 
-TO USER VOLUME SUBDIRECTORY 'dish_images';
-
--- 查看上传的文件
-LIST USER VOLUME SUBDIRECTORY 'dish_images';
-```
-
-### 2.3 利用函数识别图片
-
-利用云函数实现图像的自动识别和向量化：
-
-```sql
--- 插入单条记录，调用云函数进行图像识别和向量生成
-INSERT INTO dish_images (url, file_name, image_content, image_vector)
-VALUES 
-(
-    'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood1.jpg',
-    'RecognizeFood1.jpg',
-    -- 调用图像识别函数
-    public.fc_image_to_text('dish_recognition', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood1.jpg'),
-    -- 生成图像向量（注意：向量维度必须匹配）
-    CAST(public.fc_gen_emmbeding('multimodal', '', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood1.jpg') AS VECTOR(FLOAT, 1024))
-);
-
--- 批量插入多条记录
-INSERT INTO dish_images (url, file_name, image_content, image_vector)
-VALUES 
-('http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood2.jpg', 
- 'RecognizeFood2.jpg',
- public.fc_image_to_text('dish_recognition', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood2.jpg'),
- CAST(public.fc_gen_emmbeding('multimodal', '', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood2.jpg') AS VECTOR(FLOAT, 1024))
-),
-('http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood3.jpg', 
- 'RecognizeFood3.jpg',
- public.fc_image_to_text('dish_recognition', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood3.jpg'),
- CAST(public.fc_gen_emmbeding('multimodal', '', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood3.jpg') AS VECTOR(FLOAT, 1024))
-);
-```
-
-### 2.4 向量相似度搜索
-
-实现基于图像内容的相似度搜索：
-
-```sql
--- 查找与目标图像最相似的菜品
-WITH target_vector AS (
-    SELECT CAST(public.fc_gen_emmbeding('multimodal', '', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood5.jpg') AS VECTOR(FLOAT, 1024)) as vec
-)
-SELECT 
-    d.id,
-    d.file_name,
-    d.url,
-    d.image_content,
-    cosine_distance(d.image_vector, t.vec) as similarity_score
-FROM dish_images d, target_vector t
-ORDER BY similarity_score ASC
-LIMIT 5;
-
--- 基于已有图像查找相似图像
-SELECT 
-    d1.file_name as source_image,
-    d2.file_name as similar_image,
-    d2.image_content,
-    cosine_distance(d1.image_vector, d2.image_vector) as similarity_score
-FROM dish_images d1, dish_images d2
-WHERE d1.file_name = 'RecognizeFood1.jpg'
-  AND d1.id != d2.id
-ORDER BY similarity_score ASC
-LIMIT 5;
-```
-
-## 3.高级应用场景
-
-### 3.1 多维度图像分析
-
-结合结构化查询和向量搜索，实现复杂的分析需求：
-
-```sql
--- 查找特定类别的图像
-SELECT 
-    id,
-    file_name,
-    image_content
-FROM dish_images
-WHERE image_content LIKE '%海鲜%' 
-   OR image_content LIKE '%鱼%'
-   OR image_content LIKE '%虾%'
-   OR image_content LIKE '%蟹%'
-ORDER BY id;
-
--- 分析菜品识别结果的置信度分布
-SELECT 
-    file_name,
-    image_content,
-    -- 提取置信度（需要根据实际JSON格式调整）
-    CAST(SUBSTRING(image_content, 
-         POSITION('probability' IN image_content) + 15, 
-         8) AS DOUBLE) as confidence
-FROM dish_images
-ORDER BY confidence DESC;
-
--- 统计各类菜品数量
-SELECT 
-    CASE 
-        WHEN image_content LIKE '%牛%' THEN '牛肉类'
-        WHEN image_content LIKE '%鱼%' THEN '鱼类'
-        WHEN image_content LIKE '%虾%' OR image_content LIKE '%蟹%' THEN '海鲜类'
-        WHEN image_content LIKE '%菜%' AND image_content NOT LIKE '%非菜%' THEN '蔬菜类'
-        ELSE '其他'
-    END as category,
-    COUNT(*) as count
-FROM dish_images
-WHERE image_content NOT LIKE '%非菜%'
-GROUP BY 1
-ORDER BY count DESC;
-```
-
-### 3.2 创建图像处理管道
-
-使用动态表实现自动化的数据处理：
-
-```sql
--- 创建动态表，自动提取和聚合菜品信息
-CREATE OR REPLACE DYNAMIC TABLE dish_summary
-REFRESH_INTERVAL = '1 HOUR'
-AS
-SELECT 
-    file_name,
-    url,
-    -- 提取菜品名称（简化的字符串处理）
-    SUBSTRING(image_content, 
-              POSITION('name' IN image_content) + 9,
-              POSITION('}' IN SUBSTRING(image_content, POSITION('name' IN image_content))) - 10
-    ) as dish_name,
-    -- 提取卡路里信息
-    CASE 
-        WHEN image_content LIKE '%calorie%' THEN
-            SUBSTRING(image_content, 
-                     POSITION('calorie' IN image_content) + 12,
-                     3)
-        ELSE NULL
-    END as calorie,
-    created_at
-FROM dish_images
-WHERE image_content IS NOT NULL;
-
--- 查看动态表数据
-SELECT * FROM dish_summary;
-```

-# 通过Bluepipe实现Oracle数据库到云器Lakehouse的实时数据同步
-
-## 方案介绍
-
-30 多年来，Oracle 一直在关系数据库和数据仓库领域占有重要地位。随着 Exadata、Exalytics、Exalogic、SuperCluster 和 12c Database 等集成系统的推出，存储和计算的紧密集成使得能够使用本地基础设施更快地处理大量数据。然而，数据的数量、速度和种类急剧增加，而云为现代数据分析带来了更多可能性。例如，通过将计算与存储分离，云器Lakehouse实现了新一代的云数据平台，以share-nothing数据架构实现了计算和存储的自动即时扩展。
-![](.topwrite/assets/image_1718854284202.png)
-
-## 方案优势
-
-Bluepipe支持从Oracle到云器Lakehouse的实时数据同步。特别是在多实例、多表的复杂数据库环境中，Bluepipe实现了自动化同步，极大降低了人工配置同步作业的复杂度和工作量。对于数万张表的源数据库，Bluepipe能够做到自动配置同步任务。
-
-### 开箱即用，10 分钟完成配置
-
-* `Bluepipe`几乎可以运行在任何`Linux`系统中，支持`x86`和`arm`芯片；常见的机架式服务器、笔记本电脑，甚至树莓派都可以用来部署；
-* 极简的配置过程，默认参数即可达到最佳性能。
-
-### 全、增量一体化，无需运维干预
-
-* 全量同步与增量同步深度协同，几乎无需日常运维操作；
-* 高效的数据比对与热修复技术，始终保证数据一致性；
-* 高度鲁棒的`Schema Evolution`。
-
-### 推数据，而不是暴露端口
-
-* `Bluepipe`与您的数据库一起部署在您的内网，无需对外暴露端口；
-* 弹性`buffer size`技术，在`吞吐(Throughput)`和`延迟(latency)`之间自动平衡。
-
-## Oracle链路的独特优势
-
-`Bluepipe`基于`Oracle LogMiner`实现对变更数据的捕捉。与此同时，在以下几个方面做了深度优化：
-
-### 对DDL行为的深度兼容
-
-在`LogMiner`默认策略下，当发生`DDL`行为后，相关表上后续的`DML`操作均无法正确解析，从而导致无法正确捕捉到变更。
-`Bluepipe`维护了字典文件的自动构建策略，保证表结构变更后仍然能捕捉到正确的增量数据。
-
-### 大事务优化
-
-`Oracle Redo Log`中记录了完整的事务(`Transaction`)过程，而业务上通常仅希望拿到`commit` 之后的数据，因此，需要在传输过程中使用`buffer`来暂存尚未`commit`的变更记录。
-`Bluepipe`基于独特的内存管理技术，单节点上也能轻松应对千万量级的大事务。
-`Oracle 12.2`版本之后，对表名、字段名的最大长度支持到了 128 字节。 但因为种种原因，`LogMiner`对于无`OGG LICENSE`的实例，至今仍不支持对包含长名称的表的 DML 解析，详情参考[官方文档](https://docs.oracle.com/en/database/oracle/oracle-database/19/sutil/oracle-logminer-utility.html)。
-`Bluepipe`基于高效的流批融合技术，全面支持了此种情况下的增量数据捕捉与投递。
-
-### 适配支持`RAC`架构
-
-## 同步效果
-
-LAG：10秒左右
-同步速度：20000行/秒

-### 在Bluepipe新建同步作业
-
-请注意：
-
-1. 在选择来源时，目标表名 `{namespace}/{table}` 中的 `{namespace}`，可以用你期望的schema名字来替代，比如 `bluepipe_oracle_staging`。
-2. 在设计环节，增量复制选择“使用CDC技术实时复制”。
-   新建同步作业成功后的效果如下图：
-   ![](.topwrite/assets/image_1718871018707.png)
-   新建作业会自动启动并开始全量数据同步，之后开始持续的增量数据实时同步。

-# CHAR
-`CHAR` 是一种固定长度的字符类型，其最大长度为 255。当字符长度不足指定的最大长度时，系统不会自动使用空格填充至最大长度。在进行字符串比较时，尾随空格并不会被考虑在内。
-
-## 语法
-```
-CHAR(N)
-```
-其中，`N` 表示字符类型 `CHAR` 的最大长度，范围为 1 到 255。
-
-
-
-## 示例
-1. 创建一个固定长度为 5 的 `CHAR` 类型：
-```
-CREATE TABLE char_t(col CHAR(5));
-```
-
-2. 插入一个长度不足的字符串：
-```
-SELECT CHAR(10) 'abcd';
-```
-结果将返回一个长度为 10 的字符串，例如：`'abcd'`
-
-3. 插入一个长度超过指定长度的字符串：
-```
-SELECT cast( 'abcdef' as char(3))
-```
-结果将返回一个长度为 3 的字符串，例如：`'abc'`（仅取前 3 个字符）
-
-4. CHAR 在比较时，忽略尾随空格：
-```
-SELECT cast('abc' as char(5)) = cast('abc' as char(10));
-```
-结果将返回 `true`，因为尾随空格在比较时会被忽略。
-
-## 注意事项
-- 在进行字符串比较时，应考虑到 `CHAR` 类型的尾随空格会被忽略的特性。
-- 根据实际需求，合理选择 `CHAR` 类型与 `VARCHAR` 类型。如果数据长度固定或变化范围较小，可使用 `CHAR` 类型以提高性能；反之，如果数据长度变化较大，建议使用 `VARCHAR` 类型以节省存储空间。

-# 功能描述
-
-将表或查询结果导出到指定路径。您可以将一张表或查询结果导出为文件并保存到 Volume 的指定路径。请注意，如果指定路径下已存在同名文件，则该文件将会被覆盖。
-
-注意事项
-
-* **默认文件名**：Lakehouse 导出时，默认文件名是相同的。因此，如果您多次运行导出操作并且指定了相同的子目录（SUBDIRECTORY），新文件将覆盖上次导出的文件。
-* **避免覆盖**：为了防止意外覆盖现有文件，请确保每次导出时使用唯一的文件名或子目录。
-
-# 语法
-
-```SQL
----语法
-COPY INTO { VOLUME external_volume_name | TABLE VOLUME table_name  | USER VOLUME }  
-SUBDIRECTORY '<path>'
-FROM { [schema.]<table_name> | ( <query> ) }
-FILE_FORMAT = ( TYPE = { CSV  | PARQUET | JSON }  [ formatTypeOptions ]  ) 
-[ copyOptions ]
-```
-
-## **参数说明**
-
-* COPY INTO:表示向目录中追加数据
-
-* VOLUME支持external\_volume\_name:具体介绍参考[Volume介绍](datalake_volume.md)
-  * external\_volume\_name: 客户指定的外部存储位置，云器仅保留路径元信息。支持的存储产品有：阿里云 OSS 、腾讯云 COS 、 亚马逊云 S3。创建过程可以参考[CONNECTION创建](Datalake_StorageConnection.md)和[VOLUME创建](datalake_volume_object.md)
-  * Table Volume:Lakehouse内部存储，与内表对象共同存储与指定Schema路径下
-  * User Volume:用户账号关联的文件存储区域，Workspace User默认对该区域具备管理权限。每个Workspace都默认拥有一个具备管理权限的User Volume

-
-***
-
-* **SUBDIRECTORY**：指定子路径，参数必须填写。例如：\`subdirectory 'month=02'
-
-* **FROM**:支持直接导出表中数据，直接直接写query查询
-
-```SQL
- --直接指定表
- COPY INTO VOLUME my_volume SUBDIRECTORY 'dau_unload/'
- FROM TABLE birds
- file_format = (type = CSV);
- --将SQL结果集导出
- COPY INTO VOLUME my_volume SUBDIRECTORY 'dau_unload/'
- FROM  (select * from birds limit 1)
- file_format = (type = CSV);
-```
-
-* **formatTypeOptions**：文件格式，支持CSV、TEXT、PARQUET、JSON。其中JSON导出的格式是[JSON LINE](https://jsonlines.org/)
-
-    * CSV 格式支持的参数：
-      * sep：列分隔符，默认为 ”,“。最多支持长度为 1 的字符，例如：`'sep'=','`或者`sep = '\001'`：使用 Hive 默认的字段分隔符（不可见字符）
-      * compression：配置文件压缩格式。支持的压缩格式有：gzip/zstd/zlib。例如：`compression='gzip'`
-      * lineSep：行分隔符，默认值为"\n"。最多支持长度为 2 的字符，例如：`lineSep='$'`
-      * quote：用于转义包含特殊字符的字段。默认值为双引号“"“，例如：* `quote = '"'`：使用双引号作为转义字符。 `quote = '\''`：使用单引号作为转义字符。
-      * header：是否解析表头，默认为 false。布尔类型，例如：`header='true'`
-      * timeZone：配置时区，没有默认值。用于指定文件中时间格式的时区。例如：`timeZone = 'Asia/Shanghai'`
-      * escape：用于转义已加引号的值中的特殊字符，仅支持单字节字符。默认值为”\“，例如：`'escape'=r'\'`。转义字符用于解释数据文件中字段分隔符或换行符的特殊含义。如果某一行以反斜杠结尾，则该字符会转义为文件格式选项中指定的换行符或回车符（`lineSep`）。因此，加载操作会将此行和下一行视为一行数据。如果不需要这种转义行为，可以将转义字符设置为其他字符
-      * nullValue: 用于判定什么样的内容应该是 Null，默认值为 \`""\`，例如 \`'nullValue'='\\\N'\`或者\`'nullValue'=r'\N'\`为了避免在不确定何时需要转义的情况下手动处理转义字符，Lakehouse支持在字符串前添加`r`前缀，表示字符串中的转义字符不会被转义，可以直接输入到表达式中运行。
-      * multiLine: 是否有跨行的 csv 记录，默认值为 `false`，如果有这样的记录，需要配置 `multiLine='true'`
-      * writebom: BOM（Byte Order Mark）是位于文件开头的特殊标记字符（U+FEFF），在CSV文件中主要作用包括：明确声明文件使用UTF-8/UTF-16等Unicode编码需要配置和 帮助软件自动识别编码格式，避免解码错误。Windows版Excel依赖BOM识别UTF-8编码文件\*无BOM时中文/日文等非ASCII字符可能显示为乱码。推荐使用场景导出的CSV文件需要在**Windows Excel**中打开。`writebom=true`
-      ```SQL
-      --指定分隔符为|和压缩
-      COPY INTO VOLUME my_volume  SUBDIRECTORY 'dau_unload/'
-      FROM TABLE birds
-      file_format = (
-          type= CSV
-          sep='|'
-          compression='gzip'
-      );
-      ```
-        * headerQuotingStyle：默认值为 "needed"，可选值 "none"。"needed" 始终给header两边加引号，"none"不加引号，遇到控制字符时报错。
-        * dataQuotingStyle：默认值为 "needed"，可选值 "none-unsafe"。"needed"始终给header两边加引号，"none-unsafe" 始终不加引号，且遇到控制字符不报错（不符合 CSV 规范但我们支持）
-
-    
-    * JSON格式支持的参数:
-      * compression: 源文件/目标文件是否压缩，默认不压缩，配置如 `'compression'='gzip'`
-      * ```SQL
-        COPY INTO VOLUME my_volume  SUBDIRECTORY 'dau_unload/'
-        FROM TABLE birds
-        file_format = (
-            type= json
-        );
-        ```
-
-    
-    
-    * Parquet , ORC , BSON 格式：无
-    
-    * ```SQL
-      COPY INTO VOLUME my_volume  SUBDIRECTORY 'dau_unload/'
-      FROM TABLE birds
-      file_format = (
-          type= parquet
-      );
-      ```
-
-* **copyOptions**
-  * `overwrite=true`：清空目标文件夹后导入（含子目录）。特别注意会清空子目录。
-  * filename\_prefix = '\<prefex\_name>'。可选参数。设置文件前缀，例如：filename\_prefix = 'my\_prefix\_'
-
-  ```SQL
-   --给文件添加前缀
-   COPY INTO VOLUME my_volume  SUBDIRECTORY 'dau_unload/'

-# 使用COPY INTO导出文件
-
-将表或查询结果导出到指定路径。您可以将一张表或查询结果导出为文件并保存到 Volume 的指定路径。请注意，如果指定路径下已存在同名文件，则该文件将会被覆盖。
-
-注意事项
-
-* **默认文件名**：Lakehouse 导出时，默认文件名是相同的。因此，如果您多次运行导出操作并且指定了相同的子目录（SUBDIRECTORY），新文件将覆盖上次导出的文件。
-* **避免覆盖**：为了防止意外覆盖现有文件，请确保每次导出时使用唯一的文件名或子目录。
-
-# 语法
-
-```SQL
----语法
-COPY INTO { VOLUME external_volume_name | TABLE VOLUME table_name  | USER VOLUME }  
-SUBDIRECTORY '<path>'
-FROM { [schema.]<table_name> | ( <query> ) }
-FILE_FORMAT = ( TYPE = { CSV  | PARQUET | JSON }  [ formatTypeOptions ]  ) 
-[ copyOptions ]
-```
-
-## **参数说明**
-
-* **COPY INTO**：表示向目录中追加数据。
-
-* **VOLUME**：支持 `external_volume_name`，具体介绍参考[Volume介绍](datalake_volume.md)。
-  * `external_volume_name`：客户指定的外部存储位置，云器仅保留路径元信息。支持的存储产品有：阿里云 OSS、腾讯云 COS、亚马逊云 S3。创建过程可以参考[CONNECTION创建](Datalake_StorageConnection.md)和[VOLUME创建](datalake_volume_object.md)。
-  * **Table Volume**：Lakehouse内部存储，与内表对象共同存储于指定Schema路径下。
-  * **User Volume**：用户账号关联的文件存储区域，Workspace User默认对该区域具备管理权限。每个Workspace都默认拥有一个具备管理权限的User Volume。

-# 创建BLOOMFILTER索引
-
-## 功能
-
-布隆过滤器（Bloom Filter）是一种概率型数据结构，用于判断一个元素是否属于某个集合。本功能允许用户在表中创建布隆过滤器索引，以提高查询效率。具体介绍参考 [Bloomfilter Index](bloomfilter-summary.md)。
-
-## 语法
-
-```
-CREATE BLOOMFILTER INDEX [IF NOT EXISTS] index_name ON TABLE 
-[schema].table_name(column_name)
-[COMMENT 'comment']
-[PROPERTIES ('key'='value')]
-```
-
-**bloomfilter**：索引类型，使用布隆过滤器算法。
-
-**index_name**：要创建的索引名称，需位于指定的schema下，且在同一schema下不能重复。
-
-**schema**：可选参数，用于指定表的schema名称。
-
-**table_name**：要创建索引的表名称。
-
-**column_name**：要创建索引的列名称，目前仅支持单列索引。
-
-**COMMENT**：可选参数，用于添加关于索引的描述信息。
-
-**PROPERTIES**：可选参数，Lakehouse保留属性，方便之后扩展添加属性。当前可选参数如下：
-| 参数名称 | 描述 |
-| :---| :----|
-| analyzer |   将字符串按固定长度分割为 ngram |
-| n | ngram的长度， 例如：当 ngram 长度设为4时，字符串 "Lakehouse" 将被索引为：Lake hous e ' |
-
-## 示例
-```
-CREATE TABLE IF NOT EXISTS demo_bloomfilter_index (
-col_1 string,
-col_2 string,
-col_3 string,
-index idx_bf (col_1) bloomfilter,
-index idx_ngram_bf (col_2) bloomfilter properties ('analyzer' = 'ngram', 'n' = '10')
-) USING parquet;
-
-CREATE BLOOMFILTER INDEX IF NOT EXISTS idx_ngram_bf1 
-ON TABLE demo_bloomfilter_index(col_3)
-COMMENT 'ngram 索引'
-properties ('analyzer' = 'ngram', 'n' = '3');
-
-SHOW INDEX FROM demo_bloomfilter_index;
-```
-
-## 参考文档
-
-* [构建索引](build-inverted-index.md)
-* [删除索引](DROP-INDEX.md)
-* [列出所有索引](SHOW-INDEX.md)
-* [查看索引详情](DESC-INDEX.md)
-
-## 使用注意事项
-
-1. BLOOMFILTER INDEX 添加完成后，只有新写入的数据才会生效。旧数据不会生效。如果旧数据需要生效，必须重写数据。
-2. 一张表可以创建多个布隆过滤器索引。
-3. 类型限制：不支持 INTERVAL、STRUCT、MAP、ARRAY 等类型。如果尝试使用不支持的类型，系统将报错。
-
-## 使用说明
-
-[BLOOMFILTER INDEX使用说明](bloomfilter-summary.md)

-# CONNECTION
-
-在Lakehouse中，CONNECTION对象扮演着至关重要的角色。它负责存储第三方服务的身份认证信息和访问管理凭据，以实现数据处理过程中对敏感信息的保护。通过使用CONNECTION，用户无需将身份认证信息以明文形式暴露，从而确保数据安全。此外，CONNECTION还支持STS（Security Token Service）认证方式，允许跨账号授权访问Lakehouse外部的服务，从而进一步提高了数据访问的灵活性和安全性。
-
-## CONNECTION的类型
-
-根据其用途和连接的外部服务类型，CONNECTION对象主要分为以下三种类型：
-
-1. [创建API Connection](<create-api-connection.md>)：这种类型的CONNECTION主要用于存储和保护第三方应用服务的身份认证信息。通过API Connection，Lakehouse可以安全地通过API调用与这些服务进行交互。目前，API Connection支持的外部服务包括阿里云的函数计算FC和腾讯云的云函数服务。API Connection通常与Remote Function结合使用，以便在Lakehouse中远程调用这些服务。
-2. [创建Storage Connection](<create-storage-connection.md>)：Storage Connection主要用于存储第三方存储服务的身份认证信息，使得Lakehouse能够安全地访问和管理这些存储服务中的数据。目前支持的外部存储服务包括阿里云的对象存储OSS、腾讯云COS和AWS S3。
-3. [创建Catalog Connection](<create-catalog-connection.md>)：在数据湖架构中，Catalog Connection是一种关键组件，用于将数据湖与外部的元数据存储（例如Hive Metastore）关联起来。通过创建 Catalog Connection，用户可以实现元数据的统一管理和访问，从而直接读取存储在外部系统中的数据。Lakehouse目前只支持连接Hive。

-Lakehouse 引入了一项强大的功能，即通过 `EXTERNAL SCHEMA` 将外部数据库映射到 Lakehouse，使得用户能够在不迁移数据的情况下，直接在 Lakehouse 中查询外部数据。这一功能极大地提升了跨数据源操作和查询的便利性，为用户提供了更加灵活的数据集成解决方案。
-
-# 使用限制
-
-* 目前，云器 Lakehouse 的外部模式映射功能支持以下外部数据源：
-  * Hive on OSS（阿里云对象存储服务，支持读取和写入）
-  * Hive on COS（腾讯云对象存储服务，支持读取和写入）
-  * Hive on S3（AWS 对象存储服务，支持读取和写入）
-  * Hive on HDFS（Preview，请联系 Lakehouse 支持，仅支持读取）
-  * Databricks Unity Catalog
-* 同时支持写入和读取。写入格式支持 Parquet、ORC、Text 文件格式。
-
-# 创建 Hive External Schema
-
-## 语法
-
-### 创建存储连接
-
-首先，您需要创建一个存储连接，以连接到外部对象存储服务。
-
-```SQL
-CREATE STORAGE CONNECTION if not exists catalog_storage_oss
-    type OSS
-    ACCESS_ID='LTAIxxxxxxxxxxxx'
-    ACCESS_KEY='T8Gexxxxxxmtxxxxxx'
-    ENDPOINT='xxx';
-```
-
-### 创建 Hive Catalog 连接
-
-接着，创建一个 Catalog 连接，指向 Hive 元数据存储服务（Hive Metastore）。
-
-```SQL
-CREATE CATALOG CONNECTION if not exists connection_name
-    type hms
-    hive_metastore_uris='metastore_uris'
-    storage_connection='storage_connection';
-```
-### 创建 External Schema
-
-最后，创建一个 External Schema，将外部数据源映射到 Lakehouse。
-
-```SQL
-CREATE EXTERNAL SCHEMA if not exists schema_name
-    CONNECTION connection_name
-    options(SCHEMA='hive_database_name');
-```
-* `connection`：必选参数，指定Catalog Connection的名称。
-* `SCHEMA`：可选参数，用于映射 Hive 的数据库名称。如果未指定，Lakehouse 将默认使用创建的 `schema_name` 名称与 Hive 中的数据库进行自动映射。
-
-
-### 案例
-
-**案例一：Hive on OSS**
-
-* 创建存储连接
-
-```SQL
-CREATE STORAGE CONNECTION if not exists catalog_storage_oss   
- type OSS    
- ACCESS_ID='LTAIxxxxxxxxxxxx'    
- ACCESS_KEY='T8Gexxxxxxmtxxxxxx'   
- ENDPOINT='oss-cn-hangzhou-internal.aliyuncs.com';
-```
-
-* 创建 Catalog Connection
-  请确保 HMS 所在服务器网络与 Lakehouse 网络打通。具体打通方式可以参考 [创建阿里云终端节点服务](creating_alicloud_privatelinkservice.md)。
-
-```SQL
-CREATE CATALOG CONNECTION if not exists catalog_api_connection    
-type hms    
-hive_metastore_uris='xxxx:9083'    
-storage_connection='catalog_storage_oss';
-```
-
-* 创建 External Schema
-
-```SQL
-CREATE EXTERNAL SCHEMA if not exists my_external_schema
-    CONNECTION catalog_api_connection
-    options(SCHEMA='default');
-```
-
-* 验证是否连通Hive Catalog
-
-```SQL
---验证读取元数据
-SHOW TABLES IN my_external_schema;
-
-
---验证读取数据，读取数据时会使用STORAGE CONNECTION权限读取
-SELECT * FROM my_external_schema.my_table;
-```
-
-**案例二：Hive on COS**
-
-* 创建存储连接
-
-```sql
-CREATE STORAGE CONNECTION catalog_storage_cos 
-  TYPE COS
-  ACCESS_KEY = '<access_key>'
-  SECRET_KEY = '<secret_key>'
-  REGION = 'ap-shanghai'
-  APP_ID = '1310000503';
-```
-
-**参数**：
-* **TYPE**：对象存储类型，腾讯云应填写 `COS`（大小写不限）。
-* **ACCESS\_KEY / SECRET\_KEY**：腾讯云的访问密钥，获取方式参考：[访问密钥](https://cloud.tencent.com/document/product/598/40488)。
-* **REGION**：腾讯云对象存储 COS 的数据中心所在的地域。相同地域内云器 Lakehouse 访问腾讯云 COS 时，COS 服务将自动路由至内网访问。具体取值请参考腾讯云文档：[地域和访问域名](https://cloud.tencent.com/document/product/436/6224)。
-
-* 创建 Catalog Connection
-  请确保 HMS 所在服务器网络与 Lakehouse 网络打通。具体打通方式可以参考 [创建腾讯云终端节点服务](creating_tencentcloud_privatelinkservice.md)。
-
-```SQL
-CREATE CATALOG CONNECTION if not exists catalog_api_connection    
-type hms    
-hive_metastore_uris='xxxx:9083'    
-storage_connection='catalog_storage_cos';
-```
-```SQL
-CREATE CATALOG CONNECTION if not exists catalog_api_connection    
-type hms    
-hive_metastore_uris='xxxx:9083'    
-storage_connection='catalog_storage_oss';
-```
-
-* 创建 External Schema
-
-```SQL
-CREATE EXTERNAL SCHEMA if not exists my_external_schema

-# 物化视图创建与使用
-
-## 功能介绍
-
-根据现有表的查询，在当前指定的Schema中创建一个新的物化视图，并用查询数据填充视图。
-
-有关更多详细信息，请参阅[物化视图](MATERIALIZEDVIEW.md)。
-
-## 语法说明
-
-```SQL
-CREATE [OR REPLACE | IF NOT EXISTS] MATERIALIZED VIEW mv_name
-[ (column_list) ] 
-[CLUSTERED BY (column_name)]
-[PARTITIONED BY (column_name)]
-[ COMMENT view_comment ] 
-[BUILD DEFERRED|BUILD IMMEDIATE]
-[refreshOption]
-[DISABLE QUERY REWRITE]
-AS <query>;  
-
-refreshOption ::=
-    REFRESH 
-    [START WITH timestamp_expr]  [interval_time] VCLUSTER vcname
-```
-
-**必需参数**
-
-1. mv_name: 指定物化视图名称。
-2. AS query：物化视图所包含的查询语句。
-
-**可选参数**
-
-1. IF NOT EXISTS:可选，如果指定的物化视图名字存在，系统不会报错，但是物化视图不会创建成功。不能和OR REPLACE同时使用
-
-2. OR REPLACE:在传统数据库中，此选项用于在同一个事务内用新对象替换旧对象，并删除旧对象的数据。但在Lakehouse中，为了支持物化视图的增加、删除和修改操作，我们保留了数据以及元数据权限信息。这意味着，即使在修改表结构或SQL逻辑时，原有数据也不会丢失。此功能特别适用于添加或删除列、调整SQL处理逻辑以及变更数据类型。请注意您修改时必须使用BUILD DEFERRED ...DISABLE QUERY REWRITE语法，该语法则会禁用物化视图重写功能，如果用户不是简单的 删除列 / 添加列 添加列定义：只能是从表一路经由SELECT透传的，不能参与任何会影响其他列的计算例如 join key, group key 等
-则在 Create Or Replace 发生后，REFRESH任务会退化为一次全量刷新。如果您想体验增量计算功能请使用[DYNAMIC TABLE](dynamic-table-introduce.md)

-
-2. \<column\_list>：
-   * 可以指定列的名称或者向物化视图的列添加注释信息，可以指定列的名称无法指定列的类型，类型由 `AS <query>`中的SELECT结果推断而来，如果您希望指定类型可以在SELECT结果中显示CAST转化
-   * 如果表中有任何列是基于表达式，建议为每列提供名称。或者as \<query>中使用别名
-   ```SQL
-     --指定列的comment，当有表达式时建议指定列名字
-     CREATE MATERIALIZED VIEW mv
-     (i,j_dd comment 'test')
-     AS select i,j+1 from mv_base_a;
-     +-------------+-----------+---------+
-     | column_name | data_type | comment |
-     +-------------+-----------+---------+
-     | i           | int       |         |
-     | j_dd        | int       | test    |
-     +-------------+-----------+---------+
-     --当存在列运算表达式使用别名方式
-     CREATE  MATERIALIZED VIEW mv
-     AS select i,j+1 as j_add from mv_base_a;
-     +-------------+-----------+---------+
-     | column_name | data_type | comment |
-     +-------------+-----------+---------+
-     | i           | int       |         |
-     | j_add       | int       |         |
-     +-------------+-----------+---------+
-   ```
-
-3. partitioned by (\<col> ):指定分区，将\<column\_list>的列作为分区，分区是一种通过在写入时将相似的行分组在一起来加快查询速度的方法。使用分区可以达到数据裁剪，优化查询。
-
-   ```SQL
-      CREATE MATERIALIZED VIEW mv
-      (i,j_dd comment 'test')
-      partitioned by(j_dd)
-      AS select i,j+1 from mv_base_a;
-   ```
-
-4.CLUSTERED BY：可选，指定Hash Key。Lakehouse将对指定列进行Hash运算，将数据根据Hash值分散到各个数据分桶中。为了避免数据倾斜和热点，并提高并行执行效果，建议选择取值范围大、重复键值少的列作为Hash Key。通常在进行join操作时会有明显效果。建议在数据量大的场景下使用CLUSTERED BY，一般按照一个桶的大小在128MB到1GB之间。如果没有指定分桶，默认为256个buckets。
-
-* SORTED BY：可选，指定Bucket内字段的排序方式。建议SORTED BY和CLUSTERED BY保持一致，以获得更好的性能。当指定SORTED BY子句后，行数据将按照指定的列进行排序。
-  ```SQL
-  --创建分桶表
-  CREATE MATERIALIZED VIEW mv (i, j_dd COMMENT 'test') 
-  CLUSTERED BY (j_dd) INTO 16 BUCKETS AS
-  SELECT    i,
-            j + 1
-  FROM      mv_base_a;
-  --创建分桶并指定排序
-  CREATE MATERIALIZED VIEW mv
-  (i, j_dd COMMENT 'test')
-  CLUSTERED BY (j_dd) SORTED BY (j_dd)  INTO 16 BUCKETS  
-  AS
-  SELECT    i,
-            j + 1
-  FROM      mv_base_a;
-  ```
-
-5. COMMENT:指定物化视图的注释信息
-
-6. BUILD DEFERRED:这是一种物化视图的创建方式。与立即生成数据的`BUILD IMMEDIATE`不同，`BUILD DEFERRED`允许在创建物化视图时不立即生成数据。默认值是BUILD IMMEDIATE，当使用CREATE OR REPLACE语法时必须是BUILD DEFERRED
-
-7. refreshOption可选，刷新选项
-   * START WITH timestamp\_exp 指定开始时间，支持指定一个时间戳表达式，如果不写 START WITH 则从当前时间开始刷新
-     * `timestamp_expression`返回结果是一个标准的时间戳类型的表达式，TIMESTAMP AS OF指定的最早时间戳取决[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。如果未指定则使用当前时间戳的版本数据，例如：
-       \* `'2023-11-07 14:49:18'`，即可以强制转换为时间戳的字符串。
-       \* `cast('2023-11-07 14:49:18 Asia/Shanghai' as timestamp)`。
-       \* `current_timestamp() - interval '12' hours`。
-       \* 本身就是时间戳或可强制转换为时间戳的任何其他表达式。
-     ```
-     --指定第二天开始刷新,刷新时间间隔20个小时
-     CREATE MATERIALIZED VIEW mydt
-          (i,j)
-          REFRESH
-          START WITH current_timestamp() +INTERVAL '1' DAY
-          INTERVAL '20' HOUR
-         vcluster test_alter AS
-         SELECT    *
-         FROM      mv_base_a;
-     ```
-   * interval\_time指定时间间隔，支持[时间间隔类型interval](INTERVAL.md)，如果不写interval\_time，写了 START WITH 则只定时刷新一次START WITH 指定的时间。interval\_time时间间隔如下

-| INTERVAL '\[+ \| -]' SECOND         | 仅指定SECOND间隔                  | INTERVAL '59.999' SECOND表示59.999秒                         |
-| INTERVAL '\[+ \| -] ' DAY TO HOUR   | 同时指定DAY和HOUR间隔               | INTERVAL '1 23' DAY TO HOUR表示1天23小时                       |

-| INTERVAL '\[+ \| -] ' DAY TO SECOND | 同时指定DAY、HOUR、MINUTE和SECOND间隔 | INTERVAL '1 23:59:59.999' DAY TO SECOND表示1天23小时59分59.999秒 |
-
-day：取值范围为\[0, 2147483647]。 hour：取值范围为\[0, 23]。minute：取值范围为\[0, 59]。second：取值范围为\[0, 59.999999999]。
-
-* INTERVAL最小值是1分钟，可以用 60 SECOND 或者1 MINUTE 来表示
-  * INTERVAL支持带引号或者不带引号，以下表示是等价的：
-    \*  INTERVAL "60 SECOND"
-    \*  INTERVAL ‘60 SECOND’
-    \* INTERVAL 60 SECOND
-  * INTERVAL支持的单位：SECOND，MINUTE，HOUR，DAY
-  * INTERVAL单位不区分大小写，HOUR、hour是等价的
-
-* 在 `refreshOption` 中指定计算集群。自动刷新会消耗资源，因此需要明确指定计算集群。如果未指定，将默认使用当前会话的计算集群。您可以通过 `SELECT current_vcluster()` 查看当前会话的计算集群。
-
-  ```SQL
-  CREATE MATERIALIZED VIEW my_mv (i, j)
-  REFRESH   interval '1' MINUTE vcluster test AS
-  SELECT    *
-  FROM      mv_base_a;
-  ```
-
-8. DISABLE QUERY REWRITE：这是指物化视图不支持查询重写的特性。查询重写是指数据库优化器在对物化视图的基表进行查询时，自动判断是否可以通过查询物化视图来得到结果，如果可以，则避免了聚集或连接操作，直接从已经计算好的物化视图中读取数据。
-
-## 注意事项
-
-* 物化视图的增量刷新是基于基表的历史版本。历史版本取决于[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。此参数定义了在被删除数据被保留的时间长度，Lakehouse默认保留数据一天。根据您的业务需求，您可以通过调整 `data_retention_days` 参数来延长或缩短数据的保留周期。请注意，调整数据保留周期可能会影响存储成本。延长保留周期会增加存储需求，从而可能增加相关的费用。
-
-## 示例
-
-### 示例1 简单物化视图
-
-本示例展示了如何创建一个表 (`inventory`)，以及如何基于该表创建一个物化视图 (`mv_inventory_basic`)。接着，插入了一条数据，然后从物化视图中选择数据、刷新物化视图，最后再次从物化视图中选择数据，从而观察手工刷新物化视图的效果。
-
-```SQL
--- 创建一个名为 inventory 的表，包括 product_ID、wholesale_price 和 description 字段
-CREATE TABLE inventory (product_ID INTEGER, wholesale_price FLOAT, description VARCHAR);
-
--- 如果物化视图 mv_inventory_basic 不存在，则创建该视图，选择 inventory 表中的 product_ID、wholesale_price 和 description 字段
-CREATE MATERIALIZED VIEW IF NOT EXISTS mv_inventory_basic AS
-SELECT product_ID, wholesale_price, description
-FROM inventory;
-
--- 向 inventory 表中插入一条数据：
-INSERT INTO inventory (product_ID, wholesale_price, description) VALUES 
-    (1, 1.00, 'cog');
-
--- 从物化视图 mv_inventory_basic 中选择 product_ID 和 wholesale_price 字段，查看插入数据后的视图内容
-SELECT product_ID, wholesale_price FROM mv_inventory_basic;
-
--- 刷新物化视图 mv_inventory_basic，以确保视图内容与基表保持一致
-REFRESH MATERIALIZED VIEW mv_inventory_basic;
-
--- 再次从物化视图 mv_inventory_basic 中选择 product_ID 和 wholesale_price 字段，查看刷新后的视图内容
-SELECT product_ID, wholesale_price FROM mv_inventory_basic;
-```
-
-以上 SQL 语句展示了如何创建和使用物化视图。在实际操作中，物化视图可以显著提高查询性能，尤其是在涉及复杂计算或大量数据时。通过刷新物化视图，确保视图数据与源表数据保持一致，以提供最新的查询结果。**注意：由于在创建物化视图时没有使用调度参数因此这里是进行手动刷新**。
-
-### 示例2 带列列表和注释的物化视图
-
-```SQL
-CREATE MATERIALIZED VIEW mv_inventory_with_comment
-(product_ID, wholesale_price, description)
-COMMENT 'This is a materialized view for inventory'
-AS
-SELECT product_ID, wholesale_price, description
-FROM inventory;
-```
-
-### 示例3 带分区和聚簇的物化视图
-
-```SQL
-CREATE MATERIALIZED VIEW mv_inventory_partitioned_clustered
-
-(product_ID, wholesale_price, description)
-
-PARTITIONED BY (product_ID)
-
-CLUSTERED BY (product_ID)
-
-AS
-
-SELECT product_ID, wholesale_price, description
-
-FROM inventory;
-```
-
-### 示例4 带刷新选项和虚拟计算集群的物化视图
-
-```SQL
-CREATE MATERIALIZED VIEW mv_inventory_refresh
-
-REFRESH START WITH current_timestamp INTERVAL '1 HOUR' VCLUSTER default
-
-AS
-
-SELECT product_ID, wholesale_price, description
-
-FROM inventory;
-```
-
-修改带有刷新选项的物化视图的刷新周期：
-
-```SQL
-CREATE OR REPLACE MATERIALIZED VIEW mv_inventory_refresh
-
-BUILD DEFERRED
-
-REFRESH START WITH current_timestamp INTERVAL '1 MINUTE' VCLUSTER default
-
-DISABLE QUERY REWRITE
-
-AS
-
-SELECT product_ID, wholesale_price, description
-
-FROM inventory;
-```
-
-查看修改结果：
-
-```SQL
-DESC EXTENDED mv_inventory_refresh;
-```
-
-可以看到refresh\_interval\_second的值已经是60了，表名修改刷新周期成功。
-对于按周期自动刷新的物化视图，如果需要暂停或者恢复自动刷新，请参考：
-[修改物化视图](alter-materialzied-view.md)
-
-### 示例5 综合示例
-
-```SQL
-CREATE MATERIALIZED VIEW mv_inventory_full
-(product_ID, wholesale_price, description)
-COMMENT 'Materialized view with partition, clustering, and refresh options'
-PARTITIONED BY (product_ID)
-CLUSTERED BY (wholesale_price)
-REFRESH START WITH current_timestamp INTERVAL '1 day' VCLUSTER 'default_ap'
-AS
-SELECT product_ID, wholesale_price, description
-FROM inventory;
-
-```
-
-### 示例6：创建物化视图并添加注释
-
-重建MATERIALIZED VIEW可以复用上次结果。场景包含加列，可以重用上次的mv，添加的新的列老数据显示为null
-
-**案例**

-```SQL
-CREATE    TABLE employees (
-          emp_id int,
-          emp_name varchar,
-          dept_id int,

-# 功能
-
-本文介绍了如何创建自定义角色以及对现有角色进行替换的 SQL 语法。
-# Workspace角色管理
-## 语法
-
-```SQL
-CREATE [OR REPLACE] ROLE [IF NOT EXISTS] role_name COMMENT '';
-```
-
-- **CREATE**: 创建一个新的角色。
-- **OR REPLACE** (可选): 如果已存在同名角色，则替换该角色。
-- **IF NOT EXISTS** (可选): 如果指定的角色名称不存在，则创建新角色。如果角色已存在，不会报错，也不会创建新角色。
-- **role_name**: 指定新角色的名称。请注意，角色名称不能与系统预定义的角色名称相同。
-- **COMMENT** (可选): 为角色添加注释，可以留空或提供有关角色的信息。
-
-## 示例
-
-1. 创建一个名为 `simple_role` 的自定义角色：
-
-   ```SQL
-   CREATE ROLE simple_role;
-   ```
-
-2. 创建一个名为 `admin_role` 的角色，并为其添加注释：
-
-   ```SQL
-   CREATE ROLE admin_role COMMENT '拥有高级权限的角色';
-   ```
-
-3. 替换已存在的 `existing_role` 角色：
-
-   ```SQL
-   CREATE OR REPLACE ROLE existing_role;
-   ```
-
-4. 创建一个名为 `new_role` 的角色，如果该角色已存在，则不会创建新角色：
-
-   ```SQL
-   CREATE ROLE IF NOT EXISTS new_role;
-   ```
-
-# Instance Role 管理
-
-LakeHouse 支持在 **实例粒度（Instance-Level）** 创建角色，实现跨工作空间（Workspace）的统一权限管控，满足多团队协作场景下的精细化访问控制。需要INSTANCE_ADMIN可以执行此操作
-
-## 语法说明
-
-```SQL
--- 创建 Instance Role（若不存在）
-CREATE INSTANCE ROLE IF NOT EXISTS <role_name>;
--- 删除 Instance Role（如果存在）
-DROP INSTANCE ROLE IF EXISTS <role_name>;
--- 查看所有 Instance Role
-SHOW INSTANCE ROLES;
-```
-
-#### 示例
-
-```SQL
-
-DROP INSTANCE ROLE IF EXISTS inst_role;
-
-CREATE INSTANCE ROLE IF NOT EXISTS inst_role;
-
-SHOW INSTANCE ROLES;
-```

-### 功能描述
-
-`CREATE SCHEMA` 语句旨在创建一个新的数据模式（SCHEMA）。通过定义模式名称和可选的描述性注释，用户能够在数据管理系统中构建一个新的逻辑数据分组，从而实现数据的有序组织和高效管理。
-
-### 语法格式
-
-```Plaintext
-CREATE SCHEMA [ IF NOT EXISTS ] schema_name [ COMMENT 'comment' ];
-```
-
-### 参数详解
-
-- `schema_name`: 指明新创建的数据模式名称。
-- `IF NOT EXISTS`: 非必选参数，用于防止在数据模式已存在的情况下产生错误。
-- `COMMENT`: 为新数据模式添加描述性注释，有助于理解模式的用途和内容。
-
-### 使用示例
-
-1. 创建一个名为 `customer_data` 的新数据模式，并为其添加注释 "客户相关数据"：
-
-   ```SQL
-   CREATE SCHEMA customer_data COMMENT '客户相关数据';
-   ```
-
-2. 若需避免因数据模式已存在而产生错误，可以使用 `IF NOT EXISTS` 参数：
-
-   ```SQL
-   CREATE SCHEMA IF NOT EXISTS sales_data COMMENT '销售相关数据';
-   ```
-
-3. 创建一个具有中文注释的数据模式：
-
-   ```SQL
-   CREATE SCHEMA financial_data COMMENT '财务数据';
-   ```
-
-### 权限要求
-
-执行 `CREATE SCHEMA` 语句的用户必须具备创建数据模式的权限。具体而言，用户需要获得相应的权限点，以确保能够成功执行该操作。

-## CREATE VIEW
-
-本命令用于基于对一个或多个现有表的查询结果，在当前或指定的 SCHEMA 中创建一个新的视图。视图是一种虚拟表，它提供了对查询结果的访问，而无需直接操作底层数据表。
-
-## 语法
-
-```SQL
-CREATE [ OR REPLACE ] VIEW [ IF NOT EXISTS ] [schema_name.]view_name
-    [ (column_name comment '' [, ...]) ]
-    [ COMMENT 'comment' ]
-    AS query;
-```
-
-## 参数说明
-
-- **OR REPLACE**：此选项用于替换任何同名的已存在视图（如果存在）。需要注意的是，它不能与 `IF NOT EXISTS` 选项同时使用。使用此选项相当于先对现有的视图执行 `DROP VIEW` 操作，然后创建一个具有相同名称的新视图。
-- **column_name**：指定新视图中的列名称。如果需要为新视图中的列指定别名或添加注释，可以使用此参数。
-- **COMMENT**：为新创建的视图添加注释信息。这有助于其他用户了解视图的用途和结构。
-- **query**：用于生成视图内容的 SQL 查询语句。
-
-## 使用示例
-
-1.  创建一个名为 `myview` 的视图，包含来自 `mytable` 表的 `col1` 和 `col2` 列：
-
-   ```SQL
-   CREATE VIEW myview AS
-   SELECT col1, col2 FROM mytable;
-   ```
-
-2.  创建一个名为 `myview` 的视图，并为其指定列别名和注释：
-
-   ```SQL
-   CREATE VIEW myview (col1_alias comment 'col1_alias', col2_alias comment 'col2_alias')
-   COMMENT 'This is my view with aliased columns'
-   AS
-   SELECT col1 AS col1_alias, col2 AS col2_alias FROM mytable;
-   ```
-
-3.  创建一个名为 `myview` 的视图，只包含满足特定条件的记录：
-
-   ```SQL
-   CREATE VIEW myview AS
-   SELECT col1, col2, col3
-   FROM mytable
-   WHERE col1 > 100;
-   ```
-
-4.  使用 `OR REPLACE` 选项替换已存在的同名视图：
-
-   ```SQL
-   CREATE OR REPLACE VIEW myview AS
-   SELECT col1, col2, col4
-   FROM mytable;
-   ```
-
-5.  在指定的 SCHEMA 中创建视图：
-
-   ```SQL
-   CREATE VIEW schema_name.myview AS
-   SELECT col1, col2
-   FROM schema_name.mytable;
-   ```

-# CREATE EXTERNAL FUNCTION
-
-外部函数（EXTERNAL FUNCTION）是云器 Lakehouse 提供的强大功能，允许您通过 Python 和 Java 语言创建自定义函数（UDF），并通过远程云服务执行。这种灵活性使您能够扩展 Lakehouse 的计算能力，处理复杂的业务逻辑。支持以下云服务平台执行外部函数：
-
-* 阿里云函数计算（FC）
-* 腾讯云云函数服务
-* AWS Lambda 服务
-
-支持开发语言：
-
-* Python 3.10
-* Java 8
-
-对于以下三种不同类型的自定义函数：
-
-* UDF（用户自定义函数）：处理输入行中的一个或多个列，并为每一行返回单个结果值。
-* UDAF（用户自定义聚合函数）：对多行数据进行聚合计算，返回单个结果值。
-* UDTF（用户自定义表函数）：接收一个或多个输入参数，返回多行多列的结果集。
-
-Python 函数支持 UDF，Java 函数支持 UDF、UDAF 和 UDTF
-
-## EXTERNAL FUNCTION 创建主要流程
-
-* 用户开通云上的函数计算服务（如阿里云的函数计算FC）和对象存储服务
-
-* 将 EXTERNAL FUNCTION 执行代码、可执行文件、依赖的库、模型和数据文件，打包上传至对象存储
-
-* 授予云器 Lakehouse 操作上述服务和访问函数文件的权限
-
-* 用户执行连接和 EXTERNAL FUNCTION DDL 创建函数
-
-* 用户在云器 Lakehouse SQL 语句中使用函数
-
-* 云器 Lakehouse 根据提供的服务地址和认证信息发送 HTTP 请求调用运行函数
-
-* 云器 Lakehouse 获取响应信息返回结果
-
-## EXTERNAL FUNCTION 优势
-
-* 可以使用 EXTERNAL FUNCTION 调用外部丰富的数据处理能力，对传统 SQL 计算模型做补充。如可调用大语言模型（LLM）、图像、音视频等，补充 SQL 的非结构化数据处理能力
-* 可以直接访问外部网络，不受云器 Lakehouse 网络约束
-
-## 语法
-
-```SQL
-CREATE EXTERNAL FUNCTION [ IF NOT EXISTS ] [<database_name>.]<schema_name>.<function_name>
-  AS <class_name>
-  USING { FILE | JAR | ARCHIVE } = '<resource_uri>'[, ...]
-  CONNECTION = <api_connection_name>
-  WITH PROPERTIES ( '<property_name>' = '<property_value>'[, ...] )
-  [ COMMENT  '<comment_string>' ]
-```
-
-## 参数说明
-
-### 必选参数
-
-* `function_name`: 指定函数的名称。
-
-* `class_name`：对于 JAVA 函数，指 JAVA 函数的主类名；对于 Python 函数，为主类名和模块名的组合，例如，主程序文件为 `video_contents.py`，主类名为 `image_to_text`，AS 后的参数为 `'video_contents.image_to_text'`。
-
-* `api_connection_name`：指定连接函数计算的认证信息，具体请参考[创建连接](CREATECONNECTION.md)。
-
-* `resource_uri`：资源连接，指 EXTERNAL FUNCTION 运行所需的资源文件。需指定对应的文件地址，要求认证信息（API CONNECTION 或者内部 VOLUME）具有该文件的读取权限。您也可以指定内部 VOLUME 如 USER VOLUME 和 TABLE VOLUME 存放代码包，这样您无需再去开通云对象存储服务。虽然您可以使用内部 volume 存放函数程序包，但是您在创建 API CONNECTION 中的 code bucket 参数必须填写外部对象存储的 BUCKET 名称。
-  * **External** **Volume 格式地址**：`volume://[{workspace}.][{schema}.]{volume_name}/upper.jar`
-    * `workspace` 和 `schema` 是可选项，如果省略，将使用当前上下文默认值。
-  * **User Volume 格式地址**：`volume:user://~/upper.jar`
-    * `user` 表示使用 User Volume 协议。
-    * `~` 表示当前用户，为固定值。
-    * `upper.jar` 表示目标文件名。
-  * **Table Volume 格式地址**：`volume:table://[{workspace}.][{schema}.]{table_name}/upper.jar`
-    * `workspace` 和 `schema` 是可选项，如果省略，将使用当前上下文默认值。
-    * `table` 表示使用 Table Volume 协议。
-    * `table_name` 表示表名，需根据实际情况填写。
-    * `upper.jar` 表示目标文件名。
-
-* `WITH PROPERTIES`：指定函数的参数信息。
-  1. `remote.udf.api` - 指定运行时编译环境，支持两种选项：
-
-     * `python3.mc.v0`：当使用 Python UDF 时需要指定此选项
-     * `java8.hive2.v0`：当使用 JAVA Hive 风格 UDF 时需要指定此选项
-  2. `remote.udf.protocol` - 指定访问协议，默认值为`http.arrow.v0`，代表访问云函数的协议
-
-### 可选参数
-
-* `IF NOT EXISTS`：如果指定的函数已存在，则命令不会进行任何更改并返回一条指示函数存在的信息。如果不指定，函数存在时会直接返回错误信息。
-* `COMMENT`：指定注释信息。
-
-## 注意事项
-
-* 创建外部函数过程需要读取函数代码或可执行文件，可能需要较长时间。
-* 该命令无需启动 VC，因此不消耗 CRU。
-* 目前只支持 Java 和 Python 编程语言，支持的运行环境：Java 8 和 Python 3.10 版本
-
-# 开发指南
-
-* [创建 API CONNECTION](create-api-connection.md)
-* [Java 语言开发 External Function 指南](ExternalFunctionDevGuideJava.md)
-* [Python 语言开发 External Function指南](RemoteFunctionDevGuidePython3.md)
-
-# 使用示例
-
-## 阿里云创建 EXTERNAL FUNCTION
-
-**环境依赖**：系统已经创建 API CONNECTION，请参考 [API CONNECTION](create-api-connection.md)
-
-**步骤 1**：JAVA 语言编写 EXTERNAL FUNCTION，以下是实现大小写转换的示例代码：
-
-```java
-package com.example;
-
-import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
-import org.apache.hadoop.hive.ql.metadata.HiveException;
-import org.apache.hadoop.hive.ql.udf.generic.GenericUDF;
-import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspector;
-import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector;
-import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector.PrimitiveCategory;
-import org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory;
-
-import java.util.Locale;
-
-public class GenericUdfUpper extends GenericUDF {
-  @Override
-  public ObjectInspector initialize(ObjectInspector[] arguments) throws UDFArgumentException {
-    checkArgsSize(arguments, 1, 1);
-    checkArgPrimitive(arguments, 0);
-    if (((PrimitiveObjectInspector) arguments[0]).getPrimitiveCategory() != PrimitiveCategory.STRING) {
-      throw new UDFArgumentException("argument 0 requires to be string rather than " + arguments[0].getTypeName());
-    }
-    return PrimitiveObjectInspectorFactory.javaStringObjectInspector;
-  }
-
-  @Override
-  public Object evaluate(DeferredObject[] arguments) throws HiveException {
-    Object arg = arguments[0].get();
-    if (arg == null) {
-      return null;
-    }
-    return ((String) arg).toUpperCase(Locale.ROOT);
-  }
-
-  @Override
-  public String getDisplayString(String[] children) {
-    return "upper";
-  }
-}
-```
-
-编译代码生成 **Jar 包和其他依赖文件**，打包成 zip 压缩包
-
-**步骤 2**：上传函数程序包到指定路径
-如： `oss://hz-oss-lakehouse/functions/sentiment/UDF_code/my_upper.zip`
-函数主类：`com.clickzetta.my_upper`
-有两种方法上传文件到指定路径：
-
-* 通过 OSS 客户端直接上传
-* 在 Lakehouse JDBC 客户端（不支持 Lakehouse Web UI 使用 PUT 命令上传）通过 [PUT 命令](PUT.md) 将程序包上传至 [Volume 对象](datalake_volume.md)，并在创建函数 DDL 中引用 VOLUME 路径和上面创建的 API CONNECTION。例如：
-
-```SQL
--- 上传文件到命名为 fc_volume 的 Volume对象：
-PUT './my_upper.zip' to volume fc_volume file '/udfs/my_upper.zip';
-
--- 在创建函数时引用该 Volume 路径：
-create external function public.my_upper
-    AS 'com.clickzetta.my_upper' 
-    USING ARCHIVE 'volume://fc_volume/udfs/my_upper.zip' 
-    CONNECTION my_function_connection
-    WITH
-    PROPERTIES (
-        'remote.udf.api' = 'java8.hive2.v0'
-);
-```
-
-**步骤 3**：使用函数
-
-```SQL
-SELECT public.my_upper('a');
-```
-
-**说明**：
-
-如果您使用 USER VOLUME 替换**步骤 2** 中的 OSS 路径，USER VOLUME 为云器 Lakehouse 默认提供的个人文件存储空间（类似于操作系统的用户 HOME 目录）
-
-```SQL
--- 查看 USER VOLUME
-SHOW USER VOLUME DIRECTORY;
-
--- 上传文件至 USER VOLUME
--- !!! 注意：
--- 1. 需使用 Lakehouse JDBC 客户端工具执行 PUT 命令，文件路径为本地路径。
--- 2. 必须使用包含依赖的 JAR 包
-PUT '/Users/nero/Downloads/udf/expudf-1.0-SNAPSHOT-jar-with-dependencies.jar' TO USER VOLUME;
-
--- 删除已存在的函数定义（如有）
-DROP FUNCTION IF EXISTS public.eval_exp_internal_volume;
-
--- 创建外部函数
-CREATE EXTERNAL FUNCTION public.eval_exp_internal_volume
-AS 'com.clickzetta.hive.udf.EvalExpUdf' 
-USING FILE 'volume:user://~/expudf-1.0-SNAPSHOT-jar-with-dependencies.jar' 
-CONNECTION udf_api_conn
-WITH PROPERTIES (
-    'remote.udf.api' = 'java8.hive2.v0'
-);
-
--- 测试函数：返回字符串结果
-SELECT public.eval_exp_internal_volume(
-    named_struct('a', 1d, 'b', 4.3d, 'c', 3d), 
-    '(a+b)/c'
-).string_result;
-
--- 测试函数：返回浮点数结果
-SELECT public.eval_exp_internal_volume(
-    named_struct('a', 1d, 'b', 4.3d, 'c', 3d), 
-    '(a+b)/c'
-).double_result;
-```

-# 用CTE方式对客户进行同类群组分析
-
-## CTE
-
-[CTE(Common Table Expression) ](WITH.md)，公用表表达式，它是在单个语句的执行范围内定义的临时结果集，只在查询期间有效。它可以自引用，也可在同一查询中多次引用，实现了代码段的重复利用。
-
-## 同类群组（Revenue Cohort）
-
-同类群组（Revenue Cohort）分析是对几个不同同类群组（即客户群）的分析，以更好地了解行为、模式和趋势。
-最常见的同类群组分析类型之一着眼于基于时间的同类群组，这些群组按特定时间范围对用户/客户进行分组。例如，一家公司可能希望了解其在 1 月份开始使用该产品或开始付款的客户与 2 月份的客户相比如何。
-基于细分的群组代表使用或购买特定产品或服务的客户群。例如，您可以根据用户每周登录您的应用的时间来细分用户。
-另一种类型的群组是基于规模的群组，它按货币价值对客户进行细分。这是游戏行业（免费用户与鲸鱼用户）或 SaaS 世界中的常见做法，通过他们的 LTV 或计划对客户进行细分。
-对于本文的其余部分，我们将只关注实施基于时间的收入群组分析。
-队列分析所需的数据，在开始队列分析之前，需要以下数据：
-\*     与购买数据相关联的收入数据
-\*     用户的唯一标识符，例如客户 ID 或帐户 ID
-\*     每个用户的初始开始日期，无论是注册日期还是第一次付款。
-
-## 数据说明
-
-本文所使用的数据来自云器Lakehouse的共享样例数据，可以直接按照如下方式直接使用:
-
-```
-select * from clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore limit 10;
-```
-
-![](.topwrite/assets/image_1718761578596.png)
-
-## 分析步骤
-
-1. 临时结果集user\_cohorts：首先，我们想将用户分到群组中——在这种情况下，我们想按他们的Order Week 。
-2. 临时结果集order\_Week：接下来我们要创建一个order\_month变量。例如，客户在首次付款后一个月进行的付款的值为order\_month2。创建一个order\_Week变量。例如，客户在首次付款后一周进行的付款的order\_Week值为 2。
-3. 临时结果集cohort\_size：进一步，我们现在可以汇总cohortMonth第一步中创造的收入。这将使我们能够创建我们的rentention\_table.汇总cohortMonth第一步中创造的收入。这将使我们能够创建我们的rentention\_table.
-   构建分析模型如下：

-
-WHERE r.cohortWeek IS NOT NULL
-
-ORDER BY 1, 3;
-
-```
-
-## 回顾：物理表的方式
-
-不使用CTE，而是将每一个子查询的结果都落成物理表，则整个处理过程如下：
-
-1. 根据每个客户的升序订单日期创建特定于每个客户 ID 的订单序列列。这就是ROW\_NUMBER 分析函数在下面的查询中所做的。
-2. 创建一个新列，为客户 ID 插入先前的订单日期，以便在以后的代码块中用于计算订单之间的时间段。这就是LAG 分析函数在以下查询中所做的。
-   –请注意语句末尾的“Group By”order\_date 和 customer\_id 列。这很重要，因为客户可以在同一天拥有多个具有不同订单 ID 的订单。
-
-```
-DROP TABLE if exists eCommerce_LifeCycle_Order_Sequence;
-CREATE TABLE eCommerce_LifeCycle_Order_Sequence 
-AS
-SELECT event_date,
-       user_id,
-       ROW_NUMBER() OVER (PARTITION BY user_id ORDER BY event_date ASC) AS customer_order_sequence,
-       LAG(event_date) OVER (PARTITION BY user_id ORDER BY user_id ASC) AS previous_order_date,
-       MIN(event_date) AS first_order_date,
-       MAX(event_date) AS last_order_date
-FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore
-WHERE event_type = 'purchase'
-GROUP BY event_date,
-         user_id;
-```
-
-针对上表运行子查询以计算 order\_date 和 previous\_order\_date 列之间的天数，您将看到创建新列 days\_between\_orders 的 DATE\_DIFF 函数会发生这种情况。
-
-```
-DROP TABLE if exists eCommerce_LifeCycle_Time_Between_Orders;
-CREATE TABLE eCommerce_LifeCycle_Time_Between_Orders 
-AS
-SELECT event_date,
-       user_id,
-       customer_order_sequence,
-       CASE
-         WHEN previous_order_date IS NULL THEN event_date
-         ELSE previous_order_date
-       END AS previous_order_date,
-       DATEDIFF(event_date,previous_order_date) AS days_between_orders,
-       first_order_date,
-       last_order_date
-FROM eCommerce_LifeCycle_Order_Sequence;
-```
-
-下一个查询使用CASE 语句创建一个附加的 customer\_life\_cycle 列，以根据 days\_between\_orders 列指示订单是来自新客户、活跃客户还是已失效客户。在此示例中，如果订单发生在距上一个订单 1 到 365 天之间的任何时间，则客户被视为活跃客户；如果先前订单超过 365 天，则客户被视为已失效。这具有高度的业务特定性，因此您的可能会有所不同。
-
-```
-DROP TABLE if exists eCommerce_LifeCycle;
-CREATE TABLE eCommerce_LifeCycle 
-AS
-SELECT event_date,
-       user_id,
-       CASE
-         WHEN customer_order_sequence = 1 THEN '新客户'
-         WHEN days_between_orders > 0 AND days_between_orders < 30 THEN '活跃客户'
-         WHEN days_between_orders > 30 THEN '沉睡客户'
-         ELSE '未知'
-       END AS customer_life_cycle,
-       customer_order_sequence,
-       previous_order_date,
-       CASE
-         WHEN days_between_orders IS NULL THEN 0
-         ELSE days_between_orders
-       END AS days_between_orders,
-       first_order_date,
-       last_order_date
-FROM eCommerce_LifeCycle_Time_Between_Orders;
-```
-
-```
-select * from eCommerce_LifeCycle limit 100;
-```

-# **外部 AI 函数**：创建 Embedding 函数
-
-目标：利用阿里云百炼平台的 Embedding 函数，将文本和图片文件数据向量化，并实现以图搜图的场景。效果如下：
-
-![](.topwrite/assets/image_search.png)
-
-> 注意：完成本示例，需要您：
->
-> 1. 已安装 Docker（主要是为了保证开发环境与云上运行函数的环境一致）
-> 2. 拥有阿里云账号，并开通百炼平台的 API-KEY。参考 [阿里云百炼](https://www.aliyun.com/product/bailian)
-> 3. 已经创建好 API 连接。参考：创建 [API 连接](create-api-connection.md)
-
-### Step 1：准备开发环境
-
-1. **安装 Docker**：确保您的本地已安装 Docker：<https://www.docker.com/>
-
-2. **拉取 Docker 镜像**。在本地命令行终端（如 macOS 的 Terminal）执行：
-
-   ```
-   [Local]# docker pull quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779
-   ```
-
-3. **启动 Docker 容器**：该容器基于 `manylinux2014_x86_64` 镜像，并配置为使用 Python 3.10 环境。
-
-   ```
-   [Local]# docker run -it --name cz_func --env PATH="/opt/python/cp310-cp310/bin:$PATH" quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779 bash
-   ```
-
-> 如果容器已经停止，可以用以下命令启动并进入：
->
-> 1. **启动容器**：
->
-> ```
-> # docker start cz_func
-> ```
->
-> 2. **进入容器**：
->
-> ```
-> # docker exec -it cz_func bash
-> ```
-
-4. 在 /root 目录下创建文件夹 `embeddings`
-
-```
-[root@docker root]# cd /root ; mkdir embeddings 
-[root@docker embeddings]# cd embeddings
-[root@docker embeddings]# touch gen_embeddings.py
-```
-
-5. `cz_llm.py` 中的程序代码如下：
-
-```
-import os
-from cz.udf import annotate
-from openai import OpenAI
-import json
-
-@annotate("*->string")
-class get_embeddings(object):
-    def evaluate(self, model_type, input_string, api_key, model_name, dim=None):
-
-        if model_type == "text":
-            # 初始化OpenAI客户端，使用用户提供的API密钥
-            client = OpenAI(
-                api_key=api_key,
-                base_url="https://dashscope.aliyuncs.com/compatible-mode/v1"
-            )
-
-            input_data = input_string
-            completion = client.embeddings.create(
-                model=model_name,  # 使用用户提供的文本模型名称
-                input=input_data,
-                dimensions=int(dim),  # 指定向量维度
-                encoding_format="float"
-            )
-            result_json = json.loads(completion.model_dump_json())
-            embedding_vector = result_json['data'][0]['embedding']
-
-        elif model_type == "multimodal":
-            import dashscope
-            image = input_string
-            dashscope.api_key = api_key  # 使用用户提供的API密钥
-            input = [{'image': image}]
-            resp = dashscope.MultiModalEmbedding.call(
-                model=model_name,  # 使用用户提供的多模态模型名称
-                input=input
-            )
-            result_json = json.loads(json.dumps(resp.output, ensure_ascii=False, indent=4))
-            embedding_vector = result_json['embeddings'][0]['embedding']
-        else:
-            return "Not Valid Model Type"
-
-        if len(embedding_vector) >= 1:
-            return str(embedding_vector)
-        else:
-            return "Not Valid"
-# 添加命令行调用入口
-if __name__ == "__main__":
-    import argparse
-
-    parser = argparse.ArgumentParser(description="Get Embeddings using OpenAI or DashScope")
-    parser.add_argument('--model_type', required=True, help='Model type: text or multimodal')
-    parser.add_argument('--input_string', required=True, help='The input string or image path')
-    parser.add_argument('--api_key', required=True, help='Your API key')
-    parser.add_argument('--model_name', required=True, help='Model name')
-    parser.add_argument('--dim', default=1536, help='Vector dimensions (only for text models)')
-
-    args = parser.parse_args()
-
-    embedder = get_embeddings()
-    result = embedder.evaluate(
-        model_type=args.model_type,
-        input_string=args.input_string,
-        api_key=args.api_key,
-        model_name=args.model_name,
-        dim=args.dim
-    )
-    print(result)
-```
-
-### Step 2：下载第三方库
-
-程序依赖第三方包：`openai` 需要进行下载（其余为 Python 内置库，`os`、`json` 为 Python 内置库，无需下载。`cz.udf ` 在创建函数时系统会默认添加）。
-
-在开发环境的命令行终端执行：
-
-```
-[root@docker embeddings]# pwd
-/root/embeddings
-
-[root@docker embeddings]# pip install openai -t .
-```
-
-此时目录结构类似于：
-
-![](.topwrite/assets/vector2.jpeg)
-
-### Step 3：本地调试
-
-需要对以下 3 行代码进行修改，因为当前环境还没有加载 `cz.udf` 库：
-
-```
-...
-2 #from cz.udf import annotate   # 注释掉
-...
-6 #@annotate("*->string")  # 注释掉
-...
-```
-
-其中 API\_KEY 是阿里云百炼平台的 API-KEY，需要您注册阿里云账号，登录后在这里获取：[阿里云百炼](https://bailian.console.aliyun.com/?spm=5176.12818093_47.console-base_search-panel.dtab-product_sfm.60852cc9WIq2Db\&scm=20140722.S_sfm._.ID_sfm-RL_%E5%A4%A7%E6%A8%A1%E5%9E%8B%E6%9C%8D%E5%8A%A1%E5%B9%B3%E5%8F%B0%E7%99%BE%E7%82%BC%E6%8E%A7%E5%88%B6%E5%8F%B0-LOC_console_console-OR_ser-V_4-P0_0\&tab=api#/api)
-
-注释掉上面两行之后，保存并退出编辑脚本。请将下面的 image\_url 和 api\_key 替换为真实的参数并执行：
-
-```
-[root@docker embeddings]# export PYTHONPATH="${_PWD}:${_PWD}/lib"
-[root@docker embeddings]# python gen_embeddings.py \
-    --model_type multimodal \
-    --input_string ${image_url} \
-    --api_key ${api_key} \
-    --model_name multimodal-embedding-v1
-```
-
-### Step 4：打包上传
-
-打包之前，请将上面注释掉的两行代码取消注释。
-
-```
-...
-2 from cz.udf import annotate   # 去掉注释
-...
-8 @annotate("*->string")  # 去掉注释
-```
-
-执行打包命令前，请确保当前目录为程序目录（本示例为 `/root/cz_llm`）。
-
-```
-[root@docker embeddings]# pwd
-/root/embeddings
-[root@docker embeddings]# zip -rq ../embeddings.zip ./
-[root@docker embeddings]# ls ../
-```
-
-> 提示：如果您的环境没有 zip 命令，请使用 `yum install zip` 尝试安装。安装过程中遇到问题，请参考附录“**安装工具时报错**”。
-
-您会发现在 `/root ` 目录下有一个 `cz_llm.zip` 文件，将这个文件拷贝到 Lakehouse USER VOLUME 中：
-
-在 Docker 宿主机中执行：
-
-```
-[Local]# docker cp cz_func:/root/embeddings.zip ~/Downloads
-```
-
-现在 `cz_llm.zip ` 在宿主机的用户 `Downloads` 目录下
-
-我们使用 Lakehouse JDBC 客户端（请参考 [Lakehouse JDBC 客户端](connect-with-cli.md)），将文件上传（put）到 Lakehouse USER VOLUME 中：
-
-```
-PUT '/Users/derekmeng/Downloads/embeddings.zip' to USER VOLUME;
-```
-
-![](.topwrite/assets/image2.jpeg)
-
-### Step 5：创建并使用函数：
-
-本步骤依赖您提前创建好 API Connection，创建过程请参考：[API Connection ](create-api-connection.md)
-
-```
-CREATE EXTERNAL FUNCTION public.fc_embeddings
-AS 'gen_embeddings.get_embeddings'
-USING ARCHIVE 'volume:user://~/embeddings.zip'
-connection sg_fc_api_conn
-WITH PROPERTIES (
-'remote.udf.api' = 'python3.mc.v0'
-)
-COMMENT 'Examples:
-For text: text <input_string> <api_key> <model_name> <dim>
-For multimodal:multimodal <input_string> <api_key> <model_name>';
-```
-
-```
-# Verify
-select public.fc_embeddings('multimodal', 'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood5.jpg', '${api_key}', 'multimodal-embedding-v1');
-```
-
-执行效果：
-
-![](.topwrite/assets/images.jpeg)
-
-接下来的步骤是实现以图搜图功能的核心步骤。该查询接收一个图片 URL，将其向量化，然后与数据表（`food_images_data_vec`）中的所有图片向量进行比较。表 `food_images_data_vec` 的内容如下：
-
-![](.topwrite/assets/image_search.jpeg)
-
-向量搜图的效果：

-    result = llm.evaluate(test_text, test_prompt, API_KEY, MODEL_NAME, 0, True)
-    
-    print(f"\n输入文本: {test_text}")
-    print(f"系统提示: {test_prompt}")
-    print(f"LLM响应: {result}")
-```
-
-### Step2：下载第三方库
-
-程序依赖第三方包：`dashscope` 需要进行下载（其余为 Python 内置库，如 `os`、`http`、`json`、`sys` 等，无需下载）。`cz.udf ` 创建函数时系统会默认添加）
-
-在开发环境中的命令行终端执行：
-
-```
-[root@docker cz_llm]# pwd
-/root/cz_llm
-
-[root@docker cz_llm]# pip install dashscope -t .
-```
-
-此时目录结构类似于：
-
-![](.topwrite/assets/external_func_2.jpeg)
-
-^
-
-### Step3：本地调试
-
-将对以下 3 行做修改，因为当前环境还没有加载 `cz.udf` 库：
-
-```
-...
-2 #from cz.udf import annotate   # 注释掉
-...
-8 #@annotate("*->string")  # 注释掉
-...
-56 API_KEY = "sk-xxxxxx"  # 替换为你的API密钥
-```
-
-其中 API\_KEY 是阿里云百炼平台的 API-KEY ，需要您注册阿里云账号，登录后在这里获取：[阿里云百炼](https://bailian.console.aliyun.com/?spm=5176.12818093_47.console-base_search-panel.dtab-product_sfm.60852cc9WIq2Db\&scm=20140722.S_sfm._.ID_sfm-RL_%E5%A4%A7%E6%A8%A1%E5%9E%8B%E6%9C%8D%E5%8A%A1%E5%B9%B3%E5%8F%B0%E7%99%BE%E7%82%BC%E6%8E%A7%E5%88%B6%E5%8F%B0-LOC_console_console-OR_ser-V_4-P0_0\&tab=api#/api)
-
-注释掉上面两行之后，保存退出编辑脚本。执行：
-
-```
-[root@docker cz_llm]# export PYTHONPATH="${_PWD}:${_PWD}/lib"
-[root@docker cz_llm]# python cz_llm.py 
-正在调用LLM...
-
-输入文本: 小红书
-系统提示: 请返回该公司的国家规范的一级、二级行业，直接输出结果:一级行业":"xxx","二级行业":"xxx"，言简意赅
-LLM响应: "一级行业":"互联网","二级行业":"社交媒体"
-```
-
-### Step4：打包上传
-
-打包之前，请将上面注释掉的两行，解除注释。
-
-```
-...
-2 from cz.udf import annotate   # 去掉注释
-...
-8 @annotate("*->string")  # 去掉注释
-```
-
-执行打包命令，确保当前目录为程序目录（本示例为 `/root/cz_llm`）：
-
-```
-[root@docker cz_llm]# pwd
-/root/cz_llm
-[root@docker cz_llm]# zip -rq ../cz_llm.zip ./
-[root@docker cz_llm]# ls ../
-```
-
-> 提示：如果您的环境没有 zip 命令，请使用 `yum install zip` 尝试安装。安装过程中遇到问题，请参考附录“**安装工具时报错**”。
-
-您会发现在 `/root `目录下有一个 `cz_llm.zip` 文件，将这个文件拷贝到 Lakehouse USER VOLUME 对象中：
-
-在 Docker 宿主机中执行：
-
-```
-[Local]# docker cp cz_func:/root/cz_llm.zip ~/Downloads
-```
-
-现在 `cz_llm.zip ` 文件在宿主机的用户 `Downloads` 目录下
-
-我们用 Lakehouse JDBC 客户端（请参考 [Lakehouse JDBC 客户端](connect-with-cli.md)），将文件 put 到 Lakehouse USER VOLUME 中：
-
-```
-PUT '/Users/derekmeng/Downloads/transform_company_id.zip' to USER VOLUME;
-```
-
-![](.topwrite/assets/external_functions_3.jpeg)
-
-### Step5：创建并使用函数：
-
-本步骤依赖您提前创建好 API connection，创建过程请参考：[API Connection ](create-api-connection.md)
-
-```
-CREATE EXTERNAL FUNCTION public.fc_cz_llm
-    AS 'cz_llm.llm_call'   -- 不带py后缀的主程序文件名.主类名
-    USING ARCHIVE 'volume:user://~/cz_llm.zip' 
-    connection sg_fc_api_conn -- 需要提前创建 API Connection
-    WITH PROPERTIES (
-        'remote.udf.api' = 'python3.mc.v0'
-    )
-COMMENT 'Usage: python get_industry_classification.py <text> <prompt> <api_key> <model_name> [temperature] [enable_search]';
-```
-
-创建过程将持续 1 分钟左右。创建完成后，执行验证函数（注意替换 `'${api_key}'`）：
-
-```
-SELECT    public.fc_cz_llm (
-          '云器科技',
-          '请返回国家通用的行业分类，返回JSON 并用中文：{"一级行业":"xxx","二级行业":"xxx"}',
-          '${api_key}',
-          'qwen-plus',
-          '0.4',
-          'true'
-          ) AS llm_result;
-```
-
-执行效果如下：

-
-## 使用 Zeetapark for Python 进行信用评分
-
-在此笔记本中，我们将使用 [Zettapark](https://www.clickzetta.com/documents) Python API 进行信用卡评分演示。
-
-在此场景中，Zettabank 希望利用其现有的信用文件来分析当前的信用状况，即贷款是否正在顺利偿还，或者是否存在任何延迟/违约情况。
-
-基于当前的信用状况，Zettabank 希望基于数据集构建一个机器学习信用评分算法，以便能够自动评估贷款是否应该被批准或拒绝。
-
-### 先决条件
-
-请在运行此演示之前运行信用评分演示设置笔记本。
-
-### 1. 数据探索
-
-在此部分，我们将探索现有信用的数据集。
-
-#### 1.1 打开 Lakehouse 会话
-
-```python
-import json
-
-
-import pandas as pd
-from clickzetta.zettapark import *
-from clickzetta.zettapark.functions import *
-```
-
-```python
-# 从配置文件读取连接参数
-with open('config/config.json', 'r') as config_file:
-    config = json.load(config_file)
-
-
-schema = config['schema']
-vcluster = config['vcluster']
-
-
-print("Connecting to Lakehouse.....\n")
-
-
-# 创建会话
-session = Session.builder.configs(config).create()
-
-
-session.sql(f"CREATE SCHEMA IF NOT EXISTS {schema}").collect()
-session.sql(f"CREATE VCLUSTER IF NOT EXISTS {vcluster} VCLUSTER_SIZE=1 VCLUSTER_TYPE = GENERAL").collect()
-
-

-#### 1.3 可视化数值特征
-
-从这个可视化中，我们可以看到一些有趣的特征：
-
-* 大多数信用请求的金额较小（<50k）
-* 大多数信用期限为20个月或更短。
-* 大多数申请人的信用评分很高。
-* 大多数申请人在 Zettabank 的信贷或储蓄账户中余额不多。
-* 大多数申请人年龄小于40岁。
-
-```python
-credit_df.toPandas().hist(figsize=(15,15))
-```
-
-```
-array([[<Axes: title={'center': 'credit_request_id'}>,
-        <Axes: title={'center': 'credit_amount'}>,
-        <Axes: title={'center': 'credit_duration'}>],

-
-#### 1.4 可视化分类特征
-
-从这个可视化中，我们可以看到一些有趣的特征：
-
-* 大多数流行的信用请求与车辆购买或消费品相关。
-* 绝大多数贷款没有担保人，也没有共同申请人。
-* 大多数文件中的信用状况良好。
-* 大多数申请人是男性、外国工人、技术工人，拥有自己的房屋/公寓。
-* 更高金额的贷款（每个贷款类别的阈值不同）有更高的违约可能性。
-
-```python
-import matplotlib.pyplot as plt
-import seaborn as sns
-
-
-sns.set(style="darkgrid")
-
-
-fig, axs = plt.subplots(5, 2, figsize=(15, 30))
-df = credit_df.toPandas()
-sns.countplot(data=df, y="purpose", ax=axs[0,0])
-sns.countplot(data=df, x="other_parties", ax=axs[0,1])
-sns.countplot(data=df, x="credit_standing", ax=axs[1,0])

-
-#### 1.5 通过 Zettapark API 运行查询
-
-我们可以使用 Zettapark API 运行查询以获取各种见解。例如，让我们尝试确定不同类别的贷款范围。我们可以通过检查 Lakehouse 查询历史来了解 Zettapark API 如何作为 SQL 推送。
-
-```python
-df_loan_status = credit_df.select(col("PURPOSE"),col("CREDIT_AMOUNT"))\
-                          .groupBy(col("PURPOSE"))\
-                          .agg([min(col("CREDIT_AMOUNT")).as_("MIN_CREDIT_AMOUNT"), max(col("CREDIT_AMOUNT")).as_("MAX_CREDIT_AMOUNT"), median(col("CREDIT_AMOUNT")).as_("MED_CREDIT_AMOUNT"),avg(col("CREDIT_AMOUNT")).as_("AVG_CREDIT_AMOUNT")])\
-                          .sort(col("PURPOSE"))
-df_loan_status.toPandas()
-```
-
-### 2. 数据转换和编码
-
-对于当前用例，为了将数据准备成机器学习所需的格式，我们需要将分类值编码成数值。
-
-为了实现这一点，我们可以利用 Zettapark Python API 进行编码。
-
-#### 2.1 准备机器学习的特征矩阵
-
-在此部分，我们将利用 Zettapark Python API 准备一个随机森林分类器模型的特征矩阵。
-
-```python
-from clickzetta.zettapark.functions import when
-
-
-feature_matrix = credit_df.select(
-    when(col("purpose") == "Consumer Goods", 1)
-    .when(col("purpose") == "Vehicle", 2)
-    .when(col("purpose") == "Tuition", 3)
-    .when(col("purpose") == "Business", 4)

-
-```python
-from sklearn.ensemble import RandomForestClassifier
-
-
-rfc = RandomForestClassifier(n_estimators=100)
-rfc.fit(X_train, y_train)

-
-### 4. 测试模型
-
-```python

-### 5. 在 Lakehouse 中进行推理
-
-在下面的例子中，我们希望处理 60 个待处理的信用请求，并对是否批准贷款进行评估。数据如下所示：
-
-```python
-df_cred_req = session.table("CREDIT_REQUESTS")
-```
-
-```python
-df_cred_req.toPandas()
-```
-
-```python
-df.info()
-```
-
-```
-<class 'pandas.core.frame.DataFrame'>
-RangeIndex: 2940 entries, 0 to 2939
-Data columns (total 20 columns):

-### 6. 开发评分函数
-
-当 Zettabank 接收信用请求时，我们希望编写一个函数，该函数可以通过任务调用，对传入的微批请求进行评分。
-
-Python 函数将首先使用 Zettapark API 构建模型的输入特征，以进行评分。
-
-```python
-from clickzetta.zettapark.functions import col, when
-
-
-def process_credit_requests_fn (session, credit_requests: str, credit_assessment: str) -> int:
-    
-    # 使用 Zettapark API 直接编码构建模型的输入特征。
-    df_cred_req = session.table(credit_requests).select( 
-                            col("CREDIT_REQUEST_ID"), col("PURPOSE"),

-# DATE
-
-`DATE` 类型用于表示日期，包括年（year）、月（month）和日（day）三个部分，但不包含时区信息。这种类型在处理与时间无关的数据时非常有用，例如记录用户的出生日期或事件的发生日期。
-
-## 语法
-
-```
-DATE [year]-[month]-[day]
-```
-
-- `year`: 年份，格式为四位数字，如 2023。
-- `month`: 月份，格式为两位数字，范围从 01 到 12，如 03。
-- `day`: 日期，格式为两位数字，根据月份的不同，范围从 01 到 31，如 15。
-
-## 示例
-
-1. 插入当前日期：
-
-   ```sql
-   SELECT DATE('2023-03-15');
-   ```
-
-2. 从字符串转换为日期：
-
-   ```sql
-   SELECT DATE('2022-12-31');
-   ```
-
-3. 从当前时间获取日期部分：
-
-   ```sql
-   SELECT DATE(TIMESTAMP "2023-03-15 10:30:00");
-   ```
-
-4. 计算两个日期之间的差值：
-
-   ```sql
-   SELECT DATE('2023-04-01') - DATE('2023-03-15') AS DateDifference;
-   ```
-
-5. 将字符串转换为日期并进行比较：
-
-   ```sql
-   SELECT '2023-03-15' = DATE('2023-03-15') AS IsEqual;
-   ```
-
-## 注意事项
-
-- 当输入的月份或日期不符合实际范围时，将返回错误。
-- 在进行日期计算时，需要注意结果的合法性，避免出现不存在的日期（如 2023-02-30）。

-# DECIMAL
-`DECIMAL`类型用于表示具有特定最大精度和固定小数位数的数值。这种数据类型在处理金融、会计或其他需要精确数值计算的场景中非常有用，因为它可以避免浮点数运算的舍入误差。
-
-## 语法
-```
-DECIMAL(precision, scale)
-```
-* `precision`：表示数字的总位数，包括小数点两侧的位数。取值范围为1到38。
-* `scale`：表示小数点后的位数。取值范围为0到`precision`，且不能大于`precision`。
-
-## 示例
-```
-SELECT CAST(1234.56 AS DECIMAL(10, 2));  -- 结果为 1234.56
-SELECT CAST(123.456 AS DECIMAL(5, 3));   -- 结果为 null
-SELECT CAST(1.23 AS DECIMAL(4, 2));      -- 结果为 1.23
-SELECT CAST(1234 AS DECIMAL(6, 2));      -- 结果为 1234.00
-SELECT CAST(0.1234 AS DECIMAL(5, 4));    -- 结果为 0.1234
-```
-
-## 使用指南
-- 当`scale`为0时，表示数值为整数。
-- 当`precision`和`scale`的值相同时，表示数值为纯小数（即所有位数都在小数点后）。
-- 在进行数值转换时，如果转换结果超出了`DECIMAL`类型的范围，可能会发生数据截断或舍入。
-- 在比较`DECIMAL`类型的数值时，应考虑其精度和尺度，以避免因舍入误差导致的比较错误。
-
-## 注意事项
-- 在使用`DECIMAL`类型时，应根据实际需求合理选择`precision`和`scale`的值，以确保数值的精确性和计算的准确性。

-# 删除表中的行
-
-## 功能
-本功能允许您从指定的表中删除一行或多行数据。通过使用 WHERE 子句，您可以精确地指定需要删除的行。
-
-## 语法
-
-```SQL
-DELETE FROM table_name WHERE condition;
-```
-

-## 功能概述
-
-`DESCRIBE` 或 `DESC` 命令用于展示指定数据库架构（SCHEMA）的属性信息。掌握这个命令对于理解数据库架构的结构和元数据至关重要。通过使用 `EXTENDED` 关键字，用户可以获得更详尽的信息，如权限设置、创建时间等。
-
-## 语法结构
-
-```SQL
-DESCRIBE  SCHEMA [EXTENDED] schema_name;
-```
-
-## 参数详解
-
-* `DESCRIBE` / `DESC`：这两个关键字在本命令中可互换使用，用于查询数据库架构的属性。
-* `EXTENDED`：这是一个可选关键字，用于展示更详细的信息，如权限、创建时间等。
-* `schema_name`：指定需要查询属性的数据库架构名称。
-
-## 使用示例
-
-以下是 `DESCRIBE` 命令的一些使用示例：
-
-1. 查询名为 `ods_schema` 的数据库架构的基本属性信息：
-
-   ```SQL
-   DESCRIBE SCHEMA ods_schema;
-   ```
-
-2. 查询名为 `ods_schema` 的数据库架构的详细属性信息，包括创建者、创建时间、修改时间和权限设置：
-
-   ```SQL
-   DESCRIBE  SCHEMA EXTENDED ods_schema;
-   ```
-
-## 预期输出结果
-
-执行 `DESCRIBE  SCHEMA EXTENDED ods_schema;` 命令后，预期的输出结果可能如下：
-
-```Plain
-+---------------------+-------------------------+
-|      info_name      |       info_value        |
-+---------------------+-------------------------+
-| name                | testshareschema         |
-| creator             | UAT_TEST                |
-| created_time        | 2023-12-20 22:54:17.162 |
-| last_modified_time  | 2023-12-20 22:54:17.162 |
-| comment             |                         |
-| properties          | ()                      |
-| type                | shared                  |
-| origin_share_schema | public                  |
-| origin_share        | billing.testshareschema |
-+---------------------+-------------------------+
-```
-
-在这个输出结果中，用户不仅可以看到数据库架构的基本信息，还可以了解到创建者、创建时间、最后修改时间等详细信息。
-
-## 权限要求
-
-执行 DESC\[RIBE] SCHEMA 语句的用户必须拥有查询指定 SCHEMA 属性的权限。
-
-通过 DESC\[RIBE] SCHEMA 命令，用户可以详细了解 SCHEMA 的配置和状态，这对于数据库管理和维护至关重要。确保在执行此命令前，您已经获得了必要的权限。

-# 查看表结构
-
-## 功能描述
-
-通过使用 DESC 或 DESCRIBE 语句，用户可以查看 Lakehouse 数据库中指定表的详细结构信息，包括字段名、数据类型、是否允许为空、键信息以及默认值等。
-
-## 语法格式
-
-```
-DESC[RIBE] [TABLE] [EXTENDED] table_name;
-```
-
-## 参数说明
-
-* **DESC[RIBE]**：DESC 和 DESCRIBE 可以互换使用，都表示描述表结构的命令。
-* **TABLE**：可选关键字，用于指定查看的对象是表。
-* **EXTENDED**：可选参数，加入此关键字后，可以展示更多扩展信息，如表的大小和记录数。
-* **table_name**：指定需要查看结构的表名。支持查看表（TABLE）、视图（VIEW）、动态表（DYNAMIC TABLE）、物化视图（MATERIALIZED VIEW）。
-
-## 使用示例
-
-1. 查看表的基本结构信息：
-   ```SQL
-   DROP TABLE employees;
-   CREATE TABLE employees(id int,name string,skills array<string>);
-   INSERT INTO employees (id, name, skills) VALUES
-   (1, 'John Doe', ['Java', 'Python', 'SQL']),
-   (2, 'Jane Smith', ['C++', 'Hadoop', 'SQL']),
-   (3, 'Bob Johnson', ['Python', 'Docker']);
-    DESC employees;
-   +-------------+---------------+---------+
-   | column_name |   data_type   | comment |
-   +-------------+---------------+---------+
-   | id          | int           |         |

-# DOUBLE
-
-## 概述
-
-64位二进制浮点型（DOUBLE）是一种用于表示实数的数值数据类型，它可以存储非常大或非常小的数值。在计算机系统中，64位浮点数遵循IEEE 754标准，提供了大约15到17位的有效数字精度。
-
-## 语法
-
-```
-DOUBLE
-```
-
-## 示例
-
-1. 返回正整数1的64位浮点表示：
-
-   ```
-   SELECT +1D;
-   ```
-
-2. 将整数-6转换为64位浮点数表示：
-
-   ```
-   SELECT CAST(-6 AS DOUBLE);
-   ```
-
-3. 返回科学计数法表示的数值1.99714E+13：
-
-   ```
-   SELECT 1.99714E+13;
-   ```
-
-4. 将字符串形式的浮点数转换为64位浮点数：
-
-   ```
-   SELECT CAST('123.456' AS DOUBLE);
-   ```
-
-5. 计算两个64位浮点数的和：
-
-   ```
-   SELECT CAST(123.45 AS DOUBLE) + CAST(678.91 AS DOUBLE);
-   ```
-
-6. 比较两个64位浮点数的大小：
-
-   ```
-   SELECT CAST(123.456 AS DOUBLE) > CAST(122.345 AS DOUBLE);
-   ```
-
-7. 计算一个64位浮点数的平方根：
-
-   ```
-   SELECT SQRT(CAST(16 AS DOUBLE));
-   ```
-
-## 注意事项
-- `FLOAT`或`DOUBLE`。这是因为浮点数在计算机中的表示方式可能会导致精度损失，从而在进行比较和关联操作时产生不准确的结果。

-# 删除CONNECTION
-
-## 功能描述
-在Lakehouse中，删除CONNECTION操作用于移除不再需要的连接对象。CONNECTION对象用于存储与外部服务的连接信息，包括认证凭证和访问权限。
-
-## 语法
-
-删除CONNECTION的基本语法如下：
-
-```SQL
-DROP CONNECTION [IF EXISTS] connection_name;
-```
-**参数**
-IF EXISTS `connection_name`是用户希望删除的CONNECTION对象的名称。使用`IF EXISTS`选项可以在CONNECTION不存在时避免出现错误，确保删除操作的顺利执行。
-
-## 使用示例
-
-1. 删除特定的CONNECTION对象：
-
-   ```SQL
-   DROP CONNECTION my_connection;
-   ```
-
-   执行这个命令将会删除名为`my_connection`的CONNECTION对象。在执行删除操作之前，建议确认该CONNECTION不再被任何查询或作业使用。
-
-2. 在删除前检查CONNECTION是否存在：
-
-   ```SQL
-   DROP CONNECTION IF EXISTS my_connection;
-   ```
-
-   使用`IF EXISTS`选项可以在尝试删除一个可能不存在的CONNECTION时避免错误发生。这在自动化脚本或批量删除操作中特别有用，可以确保操作的顺利进行，即使某些CONNECTION已经不存在。

-
-```SQL
-DROP MATERIALIZED VIEW my_mv;
-```
-
-2. 删除名为 `my_mv` 的物化视图，如果该视图不存在，则不抛出错误：
-
-```SQL
-DROP MATERIALIZED VIEW IF EXISTS my_mv;
-```
-
-3. 删除多个物化视图，分别为 `mv1`、`mv2` 和 `mv3`：
-
-```SQL
-DROP MATERIALIZED VIEW mv1, mv2, mv3;
-```
-
-## 注意事项

-# 配置和使用云器Lakehouse MCP Server
-
-## 高级配置
-
-### 1. 启用MCP工具集成
-
-如果您的环境支持MCP（Model Context Protocol）工具，可以通过命令行方式添加[MCP服务器](LakehouseMCPServer.md)：
-
-```bash
-# 添加HTTP类型的MCP服务器
-Datus> .mcp add --transport http clickzetta_mcp_http http://localhost:8002/mcp
-
-# 或者添加SSE类型的MCP服务器
-Datus> .mcp add --transport sse clickzetta_mcp_sse http://localhost:8003/sse
-
-# 查看已添加的MCP服务器列表
-Datus> .mcp list
-
-# 检查MCP服务器连接状态
-Datus> .mcp check clickzetta_mcp_http
-
-# 调用MCP工具（格式：服务器名.工具名，具体工具名请通过.mcp check查看）
-Datus> .mcp call clickzetta_mcp_http.工具名称
-
-# 配置工具过滤器（可选）
-Datus> .mcp filter set clickzetta_mcp_http --allowed 工具名1,工具名2 --enabled true
-
-# 查看工具过滤器配置
-Datus> .mcp filter get clickzetta_mcp_http
-
-# 删除MCP服务器（如需要）
-Datus> .mcp remove clickzetta_mcp_http
-```
-
-**MCP 命令说明**：
-
-* `.mcp list` - 查看所有 MCP 服务器
-* `.mcp check <name>` - 检查服务器连接状态并显示可用工具
-* `.mcp call <server.tool>` - 调用特定工具，格式为“服务器名.工具名”
-* `.mcp filter set <server> --allowed 工具名1,工具名2` - 设置允许的工具列表
-* `.mcp filter get <server>` - 查看当前过滤器配置
-* `.mcp remove <name>` - 删除 MCP 服务器
-
-**重要提示**：具体可用的工具名称需要先添加 MCP 服务器，然后通过 `.mcp check <server_name>` 命令查看。
-
-#### 通过subagent使用MCP工具（推荐方式）
-
-添加MCP服务器后，建议通过subagent来使用MCP工具，这样可以在添加过程中选择需要的工具：
-
-```bash
-# 添加subagent（会启动交互式向导）
-Datus> .subagent add
-
-# 查看所有配置的subagent
-Datus> .subagent list
-
-# 为subagent构建知识库（可选）
-Datus> .subagent bootstrap agent_name
-
-# 删除subagent（如需要）
-Datus> .subagent remove agent_name
-```
-
-**subagent 命令说明**：
-
-* `.subagent add` - 启动交互式向导添加新的智能代理，可以在此过程中选择 MCP 工具
-* `.subagent list` - 列出所有已配置的子代理
-* `.subagent bootstrap <agent_name>` - 为指定代理构建专门的知识库
-* `.subagent remove <agent_name>` - 删除指定的子代理
-
-**添加 subagent 时请设置**：
-
-```
-agent_description: ClickZetta Lakehouse assistant with MCP tool integration
-```
-
-```
-rules:
-      - Detect user intent: distinguish between analysis requests and SQL generation
-        requests
-      - For analysis/explanation requests: focus on interpreting results, use markdown
-        format
-      - For SQL generation requests: provide executable statements with explanations
-        in JSON format
-      - Use MCP tools for instance switching, job history, system operations,etc
-      - When users mention "instance switching", "job history", or similar operations
-        - call MCP tools
-      - Prefer specialized analysis tools over basic data collection tools when available
-      - Use single comprehensive tools over multiple basic tool combinations when
-        possible
-      - Choose tools designed for the specific analysis type rather than generic tools
-      - When using MCP analysis tools: focus on explaining the tool results rather
-        than auto-generating SQL
-```
-
-通过 subagent 方式使用 MCP 工具的优势：
-
-* 可以在添加过程中交互式选择需要的工具
-* 为每个场景创建专门的智能代理
-* 支持构建专门的知识库来提升分析能力
-
-**MCP 工具启用后的功能**：
-
-* 实例管理和切换
-* 作业历史查询
-* 高级数据分析工具
-* 系统监控功能

-# Dify中集成Lakehouse MCP Server
-
-Dify 的 Agent 应用中，支持直接集成来自外部 [MCP](https://modelcontextprotocol.io/introduction) 服务器的[工具](https://modelcontextprotocol.io/docs/concepts/tools)。这给Lakehouse与您的Dify AI应用集成提供了新方式。
-Lakehouse MCP Server通过这种方式实现和Dify的集成，来自Lakehouse MCP Server的丰富的工具可以在Dify 的 Agent 轻松调起来。
-
-## Dify MCP 服务器管理界面
-
-登录 Dify 后，在左侧导航栏中依次点击 **工具** → **MCP**，即可进入外部 MCP 服务器的管理页面。在这里，你可以统一管理所有为自身应用配置的 MCP 服务器。
-
-## 添加 Lakehouse MCP 服务器
-
-首先你需要部署支持[HTTP协议的Lakehouse MCP Server](LakehouseMCPServer_intro.md)
-
-:-: ![](.topwrite/assets/image_1756885164463.png =815)
-
-点击 **添加 MCP 服务器（HTTP**），即可集成Lakehouse MCP Server工具服务。需要填写如下信息：
-
-* **服务器 URL**：Lakehouse MCP 服务器的 HTTP 接口地址，例如集成 Notion 时为 `http://192.168.1.220:8001/mcp`。
-* **名称与图标**：自定义服务器名称，建议选择能清晰体现工具用途的名字。Dify 会自动尝试获取服务器域名的图标，你也可以手动上传。比如：clickzetta-mcp-server-mcp-220
-* **服务器标识符**：Dify 用于区分服务器的唯一 ID。规则：小写字母、数字、下划线或连字符，最多 24 个字符。比如clickzetta\_mcp\_mcp\_220
-
-服务器 ID 一旦创建即无法更改。如果更改服务器 ID，所有依赖该服务器工具的 Agent 或 Workflow 都会失效。这一设计对于[应用迁移](https://docs.dify.ai/zh-hans/guides/tools/mcp##application-portability)尤为重要。
-
-添加服务器后，Dify 会自动执行如下操作：
-
-1. **检测可用工具**：自动识别该服务器能提供哪些工具功能。
-2. **处理授权流程**：如服务器需要身份验证，则自动发起 OAuth 授权流程。
-3. **获取工具定义**：下载各工具的接口定义（schema）。
-4. **同步工具列表**：将识别到的工具加入 Agent 或Workflow应用的构建页面。
-
-当 Dify 成功获取到至少一个可用工具后，会在页面中显示该服务器的信息卡片：
-
-:-: ![](.topwrite/assets/image_1756885349165.png =806)
-
-## 管理已连接服务器
-
-点击对应服务器卡片，可进行以下操作：
-
-* **更新工具**：重新从服务器获取最新工具信息，适用于服务方新增或调整功能后更新。
-
-* **重新授权**：点击授权状态，更新服务器的访问权限（如令牌失效需重新授权）。
-
-* **编辑配置**：可修改服务器信息。
-
-更改服务器 URL 会触发重新授权，修改服务器 ID 会让已有应用失效！
-
-:-: ![](.topwrite/assets/image_1756885405845.png =478)
-
-* **移除服务器**：断开服务器连接。此后所有依赖该服务器工具的应用都会报错，直到你重新连接或删除相关工具。
-
-:-: ![](.topwrite/assets/image_1756885449635.png =473)
-
-当服务器配置完成后，其下的工具会出现在应用构建时的工具选择区：
-
-## 设计Agent 应用
-
-:-: ![](.topwrite/assets/image_1756885639345.png =816)
-

-# 基于云器Lakehouse构建面向ELT的Modern Data Stack
-
-随着企业数据量和数据架构的日益复杂，企业急需寻找更快、更高效、更节省成本的数据管理和分析方法。近年来，现代化数据栈（Modern Data Stack，简称 MDS）不断创新发展，受到了广泛的关注。
-
-## MDS是什么？
-
-MDS是一系列基于云的数据工具和技术的总称，它们以云数据仓库、数据湖或Lakehouse为核心，实现了数据的存储、处理、分析和可视化。在过去十年里，以Snowflake、AWS Redshift、GCP BigQuery、MaxCompute为代表的云数据仓库迅速发展壮大，并逐渐演变为集数据仓库和数据湖于一体的Lakehouse架构，它们利用大规模并行处理和SQL支持，使得大数据的处理变得更快、更便宜。在此基础上，涌现了许多低代码、易集成、可扩展且经济的云原生数据工具，如Fivetran、Airbyte、dbt、dagster、Looker等。MDS改变了企业数据管理和分析的方式，让数据变得更加有价值。
-
-云器 Lakehouse 就是在这样的背景下诞生的，它是一个专注于数据的平台，帮助企业管理数据并充分利用数据，为企业构建现代化数据栈 MDS 提供全新的方案。
-
-## 现代数据栈有哪些关键特征？
-
-1. 云优先。MDS基于云，具有更强的可扩展性和弹性，而且可以轻松地与现有的云基础设施集成。
-2. 以云数据仓库/数据湖/Lakehouse为中心。MDS旨在与Redshift、BigQuery、Snowflake、Databricks、MaxCompute、云器Lakehouse等云数据仓库，以及数据湖和Lakehouse无缝集成。
-3. 模块化设计。MDS可以防止供应商锁定，为企业提供更大的灵活性和对数据栈的控制权。
-4. 以SaaS或开源为主。虽然开源是一件好事，但它需要较高的专业水平，因此SaaS的全托管模式更受欢迎。
-5. 降低门槛。借助MDS，企业内的每个人都可以获取和使用他们需要的数据，而不是将数据局限在某些特定的团队或部门。这有助于实现数据的民主化，并培养企业的数据文化。
-
-## 传统数据栈与现代化数据栈的差别
-
-### 传统数据栈：
-
-* 需要高技术水平
-* 依赖大量基础设施
-* 耗费时间
-
-### 现代化数据栈：
-
-* 打破云和数据的束缚
-* 简便易用
-* 工具套件适合非技术人员和业务部门使用
-* 节约时间
-
-## 为什么数据栈很重要？
-
-“时间就是金钱。”这句老话虽然陈旧，但却是事实，尤其对于数据驱动的公司而言。数据栈处理原始数据的效率决定了数据分析和数据科学团队获取数据价值的速度。拥有合适的工具是现代化数据栈的关键，也是公司成功的关键。
-
-## MDS的基本组成部分
-
-要了解 MDS 工具的优势并做出恰当的工具选择，首先需要了解数据平台的各个组件以及为每个组件提供服务的工具的通用功能。
-
-数据平台的基本组件（按照数据流方向）包括：
-
-* 数据摄取（**E**）
-* 数据存储与处理（**L**，数据仓库/数据湖/Lakehouse）
-* 数据转换（**T**）
-* 指标层（Headless BI）
-* 商业智能工具
-* 逆向ETL
-* 编排（工作流引擎）
-* 数据管理、质量和治理

-
-## 从ETL到ELT
-
-ETL 和 ELT 都描述了将数据集成用于在数据仓库、Lakehouse中进行数据分析、商业智能和数据科学之前清理、丰富和转换来自各种来源的数据的过程。
-
-* **E**xtract（抽取）是指从 SQL 或 NoSQL 数据库、XML 文件或云平台等源提取数据的过程。
-* **T**ransform（转换）是指转换数据集的格式或结构以匹配目标系统的过程。
-* **L**oad（加载）是指将数据集放入目标系统（数据仓库、Lakehouse）的过程。
-
-![](.topwrite/assets/image_1718933554740.png)
-
-### ETL
-
-#### **ETL 代表 Extract > Transform > Load**
-
-在 ETL 过程中，数据转换是在数据仓库外部的暂存区域中执行的，并且在加载之前必须转换整个数据。因此，转换较大的数据集可能需要很长时间，但一旦 ETL 过程完成，就可以立即进行分析。
-
-#### ETL流程
-
-1. 从源中提取预定的数据子集。
-2. 数据在暂存区域中以某种方式进行转换，例如数据映射、应用串联或计算。为了应对传统数据仓库的限制，有必要在加载数据之前对其进行转换。
-3. 数据被加载到目标数据仓库系统中，并准备好由BI 工具或数据分析工具进行分析。
-
-![](.topwrite/assets/image_1718933568004.png)
-
-### ETL
-
-#### **ELT 代表 Extract > Load > Transform**
-
-在 ELT 过程中，数据转换是在目标系统本身中根据需要执行的。因此，转换步骤花费的时间很少，但如果云解决方案中没有足够的处理能力，则可能会减慢查询和分析过程。
-
-#### ELT流程
-
-1. 所有数据均从源中提取。
-2. 所有数据都会立即加载到目标系统（ 数据仓库、 Lakehouse）中。这可以包括原始数据、非结构化、半结构化和结构化数据类型。
-3. 数据在目标系统中进行转换，并准备好由 BI 工具或数据分析工具进行分析
-
-通常，ELT 的目标系统是基于云的数据仓库或 Lakehouse。Amazon Redshift、Snowflake、Databricks 和 云器Lakehouse 等基于云的平台提供近乎无限的存储和强大的处理能力。这允许用户近乎实时地提取和加载他们可能需要的任何和所有数据。云平台可以随时转换任何 BI、分析或预测建模需要的数据。
-
-![](.topwrite/assets/image_1718933580647.png)
-
-### 为什么选择ELT？
-
-* **实时、灵活的数据分析**。 用户可以灵活地从任何方向探索完整的数据集，包括实时数据，而无需等待 数据工程师提取、转换和加载更多数据。
-* **更低的成本和更少的维护**。 ELT 受益于基于云的平台的强大生态系统，该生态系统提供更低的成本和各种存储和处理数据的计划选项。而且，鉴于所有数据始终可用且转换过程通常是自动化且基于云的，ELT 过程通常需要很少的维护。
-

-
-### ELT在MDS中的位置
-
-![](.topwrite/assets/image_1718933593607.png)
-
-#### 数据摄取-Airbyte
-
-Airbyte是领先的数据集成平台，适用于从 API、数据库和文件到数据仓库、数据湖和Lakehouse的 ETL/ELT 数据管道。
-
-Airbyte 已经为 API、数据库、数据仓库和Lakehouse提供了包含 300 多个连接器，同时开发新的连接器也非常方便，以支持多源著称，**特别适合长尾数据源的场景**。
-
-#### 数据存储与处理-云器Lakehouse
-
-云器 Lakehouse是一种湖仓架构的全托管数据管理及分析服务。云器 Lakehouse以单一引擎满足数仓构建、数据湖探查分析、离线和实时数据处理与分析、业务报表等场景需求，通过存算分离、Serverless弹性算力、智能优化特性满足企业不同阶段对扩展性、成本和性能需要。内置数据集成、开发与运维、数据资产管理等开通即用服务，极大简化数据开发与管理工作、加速企业数据洞察及价值实现。
-
-#### 数据转换-dbt
-
-dbt 使数据分析师和工程师能够使用与软件工程师构建应用程序相同的实践来转换数据。使用 dbt 的分析师只需编写 select 语句即可转换数据，而 dbt 则负责将这些语句转换为数据仓库中的表和视图。
-
-这些select语句或“模型”形成一个 dbt 项目。模型经常相互构建 - dbt 可以轻松*管理模型之间的关系*、*可视化这些关系*，并通过*测试*确保转换的质量。
-
-dbt 通过管理事务、删除表和管理架构更改来避免编写样板 *DML* 和 *DDL*。只需使用 SQL select 语句或返回所需数据集的 Python DataFrame 编写**业务逻辑**，然后 dbt 负责物化。
-
-dbt 生成有价值的元数据来查找长时间运行的查询，并具有对标准转换模型（例如完整或增量加载）的内置支持。
-
-#### 数据工作流-dagster
-
-Dagster 是一个编排器，旨在开发和维护数据资产，例如表、数据集、机器学习模型和报告。
-
-您可以声明要运行的函数以及这些函数生成或更新的数据资产。然后，Dagster 可以帮助您在正确的时间运行您的功能并使您的资产保持最新状态。
-
-Dagster 旨在用于数据开发生命周期的每个阶段 - 本地开发、单元测试、集成测试、暂存环境，一直到生产。
-
-与 dbt 一样，它强制执行最佳实践，例如编写声明性、抽象、幂等和类型检查函数以尽早捕获错误。Dagster 还包括简单的单元测试和方便的功能，使管道可靠、可测试和可维护。它还与 Airbyte 深度集成，允许将*数据集成为代码*。

-
-#### 数据转换（dbt）
-
-##### 配置DBT的profile.yml
-
-这里的target:指向clickzetta\_uat，也就是说该项目里的数据转换都是运行在clickzetta\_uat上。目标表将会输出到云器Lakehouse的名为ql\_ws的workspace下的modern\_data\_stack schema里。计算资源会使用名为default的vcluster。
-
-```SQL
-mds_dbt:
-  target: clickzetta_uat
-  outputs:
-    mds_source:
-      type: postgres
-      host: 172.17.1.220
-      port: 5432
-      user: metabase
-      pass: metasample123
-      dbname: mds_source

-      workspace: ql_ws
-      instance: ***
-      vcluster: default
-      username: ***
-      password: ***
-      database: ql_ws
-      schema: modern_data_stack
-      threads: 8
-      keepalives_idle: 0
-    mysql_employees:
-      type: mysql

-      password: metasample123
-      driver: MySQL ODBC 8.0 ANSI Driver
-      threads: 2
-      keepalives_idle: 0
-```
-
-##### 定义DBT的source.yml
-
-```SQL
-version: 2
-
-sources:
-  - name: ql_ws
-    database: ql_ws
-    schema: modern_data_stack
-    tables:
-      - name: orders
-        identifier: _airbyte_raw_orders
-        description: "订单表，包含所有订单数据。"
-      - name: users
-        identifier: _airbyte_raw_users
-        description: "用户表，包含用户信息。"
-      - name: departments
-        identifier: departments
-        description: "员工信息，departments table"
-      - name: dept_emp
-        identifier: dept_emp
-        description: "员工信息，dept_emp table"
-      - name: dept_manager
-        identifier: dept_manager
-        description: "员工信息，dept_manager table"
-      - name: employees
-        identifier: employees
-        description: "员工信息，employees table"
-      - name: salaries
-        identifier: salaries
-        description: "员工信息，salaries table"
-      - name: titles
-        identifier: titles
-        description: "员工信息，titles table"
-```
-
-##### 开发DBT的转换模型
-
-DBT 会根据 SELECT 语句生成和文件名一样的目标表或者视图，这个由 `dbt_project.yml` 里的配置确认。比如：
-
-models:
-
-mds\_dbt:
-
-+materialized: "table"
-
-表示数据转换目标类型为table，而不是view。如果需要生成的是view，需要设置成：
-
-models:
-
-mds\_dbt:
-
-+materialized: "view"
-
-以下是数据转换模型：
-
-user\_augmented.sql
-
-```SQL

-# EXTERNAL FUNCTION 开发指南
-
-## 概述
-
-EXTERNAL FUNCTION 是一种在数据库中直接执行外部程序或脚本的机制。通过使用外部函数，您可以将数据库与外部程序或脚本进行交互，从而实现更丰富的功能。
-
-## 支持的编程语言
-
-目前支持的编程语言包括 Java 和 Python。
-
-## Java 语言
-
-### 1. 编写 Java 类
-
-首先，您需要编写一个 Java 类，并实现一个静态方法作为外部函数的入口点。例如，创建一个名为 `MyJavaClass` 的 Java 类，并实现一个静态方法 `hello`：
-
-```java
-public class MyJavaClass {
-    public static String hello(String name) {
-        return "Hello, " + name + "!";
-    }
-}
-```
-
-### 2. 将 Java 类编译为 JAR 文件
-
-将编写好的 Java 类编译为 JAR 文件。例如，将 `MyJavaClass` 编译为 `myjavaclass.jar`。
-
-### 3. 在数据库中注册 Java 类
-
-在数据库中注册 Java 类，以便可以在外部函数中使用。例如，在 MySQL 数据库中，可以使用以下命令注册：
-
-```sql
-CREATE FUNCTION my_hello FUNCTION
-  -> 'MyJavaClass.hello'
-  -> RETURNS STRING
-  -> LANGUAGE JAVA
-  -> DATABINARY AS '/path/to/myjavaclass.jar';
-```
-
-### 4. 使用外部函数
-
-在数据库中调用外部函数，例如：
-
-```sql
-SELECT my_hello('World');
-```
-
-## Python 语言
-
-### 1. 编写 Python 脚本
-
-首先，您需要编写一个 Python 脚本，并实现一个函数作为外部函数的入口点。例如，创建一个名为 `my_python_script.py` 的 Python 脚本，并实现一个函数 `hello`：
-
-```python
-def hello(name):
-    return "Hello, " + name + "!"
-```
-
-### 2. 将 Python 脚本保存到数据库
-
-将编写好的 Python 脚本保存到数据库中。例如，在 MySQL 数据库中，可以使用以下命令保存：
-
-```sql
-CREATE FUNCTION my_hello FUNCTION
-  -> 'hello'
-  -> RETURNS STRING
-  -> LANGUAGE PYTHON
-  -> DATABINARY AS '/path/to/my_python_script.py';
-```
-
-### 3. 使用外部函数
-
-在数据库中调用外部函数，例如：
-
-```sql
-SELECT my_hello('World');
-```
-
-## 使用示例
-
-### 示例 1：计算圆的面积
-
-使用 Python 脚本计算圆的面积，并在数据库中调用该外部函数。
-
-1. 编写 Python 脚本 `calculate_circle_area.py`：
-
-```python
-def calculate_circle_area(radius):
-    return 3.14159 * radius * radius
-```
-
-2. 将 Python 脚本保存到数据库：
-
-```sql
-CREATE FUNCTION calculate_circle_area FUNCTION
-  -> 'calculate_circle_area'
-  -> RETURNS DECIMAL(10, 2)
-  -> LANGUAGE PYTHON
-  -> DATABINARY AS '/path/to/calculate_circle_area.py';
-```
-
-3. 在数据库中调用外部函数：
-
-```sql
-SELECT calculate_circle_area(5);
-```
-
-### 示例 2：查询股票价格
-
-使用 Java 类查询股票价格，并在数据库中调用该外部函数。
-
-1. 编写 Java 类 `StockPriceFetcher`：
-
-```java
-public class StockPriceFetcher {
-    public static String getStockPrice(String stockCode) {
-        // 查询股票价格的逻辑
-        return "100.0";
-    }
-}
-```
-
-2. 将 Java 类编译为 JAR 文件。
-
-3. 在数据库中注册 Java 类：
-
-```sql
-CREATE FUNCTION get_stock_price FUNCTION
-  -> 'StockPriceFetcher.getStockPrice'
-  -> RETURNS STRING
-  -> LANGUAGE JAVA
-  -> DATABINARY AS '/path/to/stock_price_fetcher.jar';
-```
-
-4. 在数据库中调用外部函数：
-
-```sql
-SELECT get_stock_price('AAPL');
-```
-
-通过上述示例，您可以更好地理解如何使用 EXTERNAL FUNCTION 将数据库与外部程序或脚本进行交互。请根据您的实际需求进行相应的调整和优化。

-# EXTERNAL SCHEMA
->**【预览发布】本功能当前处于公开预览发布阶段。**
-## 简介
-
-外部 Schema（EXTERNAL SCHEMA）是 Lakehouse 提供的一项查询外部数据源的功能，借助 EXTERNAL SCHEMA 可以实现与外部元数据服务（如 HMS）的访问以及外表的批量映射，无需将数据导入 Lakehouse。例如，通过与Hive的Database建立映射，并利用Hive元数据服务（HMS）接口，外部Schema能够直接获取Hive的元数据信息，但不会在Lakehouse中实际创建表结构。
-使用 EXTERNAL SCHEMA 可以带来如下收益：
-1. **直接查询**：通过 EXTERNAL SCHEMA，用户可以直接对外部数据库（如 Apache Hive）中的数据进行查询，而无需进行复杂的数据导入过程。由于 Lakehouse 性能更优，也可以起到为第三方引擎加速查询的作用。
-2. **数据转换和导入**：结合使用`INSERT INTO ..SELECT`语句，用户可以实现数据的提取、转换和加载（ETL），将查询结果直接写入到Lakehouse的表中。
-3. **实时联接**：EXTERNAL SCHEMA支持将Lakehouse的表与外部数据源中的数据进行实时联接，这意味着用户可以在数据发生变化时直接查询，而不是等待数据重新加载。
-4. **删除行为说明**：删除外部 Schema 不会删除 Hive 中的 Database，因为外部 Schema 仅是与 Hive 中的 Database 建立了映射关系，删除操作只会移除 Lakehouse 中的外部 Schema 元数据信息。
-
-这种设计提供了极大的灵活性和便利性，因为它减少了数据迁移的需要，并使得用户能够实时地查询和分析存储在外部数据源中的数据。
-## 外部Catalog和外部Schema使用关系
-外部 Catalog 和外部 Schema 形成两层映射结构。外部 Catalog 是顶层容器，直接映射外部数据系统；外部 Schema 是中间层容器，提供细粒度的数据组织。通过将外部Schema关联到内部Catalog，您可以在同一工作空间中统一查询外部和内部表，只需使用 `schema.table` 的简单格式即可。
-## 支持的范围
-
-* Hive on OSS（阿里云对象存储服务）
-* Hive on COS（腾讯云对象存储服务）
-* Hive on GCS（Google云对象存储服务）
-* Hive on HDFS (Preview，请联系 Lakehouse 支持)
-* Databricks
-* 同时支持写入和读取。写入格式支持 Parquet、ORC、Text 文件格式。
-
-## 外部Schema与外部表的区别
-
-* **External Schema**：直接与 Hive 元数据服务（HMS）交互，通过 HMS 接口直接获取 Hive 的元数据信息。
-* **外部表：** 用户可以自定义创建表，指定列内容和表名。
-* **External Schema 限制**：由于是直接映射 HMS，无法在 External Schema 下直接创建、删除表或重命名表。
-* **外部表优势：** 支持重命名和修改注释等操作，因为它们是在内部 Schema 下创建的。
-
-## 外部Schema计费
-
-* **存储费用：** 外部表不产生存储费用，因为数据不存储在Lakehouse中。
-* **计算费用：** 使用外部表进行计算会消耗计算资源，因此会产生计算费用。
-
-## 外部Schema权限
-
-* **创建外部Schema权限：** 需要具有创建Schema（create schema）的权限。
-* **删除外部Schema权限：** 需要具有删除（drop）权限。
-* **外部 Schema 下表的权限**：目前单独表无法单独授权，只支持 ALL TABLES 权限。
-
-
-## 管理
-
-云器 Lakehouse 提供了创建和删除 EXTERNAL SCHEMA 的命令，以便用户可以根据需要管理这些外部数据源的访问权限和配置。
-
-- **创建EXTERNAL SCHEMA**：用户可以通过`CREATE EXTERNAL SCHEMA`命令来创建一个新的EXTERNAL SCHEMA，从而开始与外部数据库进行交互。具体的语法和参数设置可以在[创建EXTERNAL SCHEMA](CREATEEXTERNAlLSCHEMA.md)文档中找到。
-- **删除EXTERNAL SCHEMA**：如果某个EXTERNAL SCHEMA不再需要，或者用户希望移除对外部数据库的访问权限，可以使用`DROP SCHEMA`命令来删除它。相关的操作步骤和注意事项在[删除EXTERNAL SCHEMA](DROPSCHEMA.md)文档中有详细说明。
-
-## 权限说明
-
-* **创建外部Schema权限：** 需要具有创建Schema（create schema）的权限。
-* **删除外部Schema权限：** 需要具有删除（drop）权限。
-* **外部 Schema 下表的权限**：目前单独表无法单独授权，只支持 ALL TABLES 权限。
-
-
-## 约束限制
-**支持的数据源**：目前，EXTERNAL SCHEMA 主要支持访问 Hive Metastore 元数据服务，且数据需要存储在 HDFS 或阿里云、腾讯云、谷歌云对象存储服务中。
-**操作限制**：在外部 Schema 下，不支持执行创建表、删除表等操作，因为它们是直接映射的。此外，外部 Schema 下的表仅支持只读操作，不允许进行插入、更新、截断或删除等数据操作语言（DML）操作。用户可以执行查询和连接操作，并能基于这些表创建视图。
-**删除行为说明：** 删除外部Schema不会删除源系统中的映射对象（如Hive Database及其包含的表）。
-
-## 使用样例
-
-#### **1. 连接阿里云 OSS**
-
-要连接阿里云 OSS，您需要以下参数，具体参考 *[阿里云OSS文档](https://help.aliyun.com/zh/oss/developer-reference/configure-ossutil)*：
-
-首先，您需要创建一个存储连接，以连接到外部对象存储服务。
-
-```SQL
-CREATE STORAGE CONNECTION if not exists catalog_storage_oss
-    type OSS
-    ACCESS_ID='LTAIxxxxxxxxxxxx'
-    ACCESS_KEY='T8Gexxxxxxmtxxxxxx'
-    ENDPOINT='xxx';
-```
-接着，创建一个目录连接，指向 Hive 元数据存储服务（Hive Metastore）。
-
-```SQL
-CREATE CATALOG CONNECTION if not exists connection_name
-    type hms
-    hive_metastore_uris='metastore_uris'
-    storage_connection='storage_connection';
-```
-
-```SQL
-CREATE EXTERNAL SCHEMA if not exists schema_name
-    CONNECTION connection_name
-    options(SCHEMA='hive_database_name');
-```
-
-* `connection`：必选参数，指定目录连接的名称。
-* `SCHEMA`：可选参数，用于映射 Hive 的数据库名称。如果未指定，Lakehouse 将默认使用创建的 `schema_name` 名称与 Hive 中的数据库自动映射。

-# External Function 开发指南（Java）
-
-本篇文档将介绍如何使用Java语言开发UDF、UDAF、UDTF类型的外部函数。
-注：External Function 当前处于预览阶段，需要使用文档中说明的控制参数进行启用。
-
-# UDF
-
-云器 Lakehouse UDF 支持基于 Hive UDF API 规范开发函数，支持使用 GenericUDF (org.apache.hadoop.hive.ql.udf.generic.GenericUDF) 和 UDF (org.apache.hadoop.hive.ql.exec.UDF) 开发标量函数。
-
-## 开发UDF
-
-创建MAVEN项目，在pom.xml添加依赖。
-
-```XML
-<dependency>
-    <groupId>org.apache.hive</groupId>
-    <artifactId>hive-exec</artifactId>
-    <version>2.3.8</version>
-    <scope>provided</scope>
-    <exclusions>
-        <exclusion>
-            <groupId>org.pentaho</groupId>
-            <artifactId>*</artifactId>
-        </exclusion>
-    </exclusions>
-</dependency>
-```
-
-编写UDF代码，示例如下：
-
-```Java
-package com.example;
-
-import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
-import org.apache.hadoop.hive.ql.metadata.HiveException;
-import org.apache.hadoop.hive.ql.udf.generic.GenericUDF;
-import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspector;
-import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector;
-import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector.PrimitiveCategory;
-import org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory;
-import org.apache.hadoop.hive.serde2.objectinspector.primitive.StringObjectInspector;
-
-import java.util.Locale;
-
-public class GenericUdfUpper extends GenericUDF {
-
-  private StringObjectInspector soi;
-
-  @Override
-  public ObjectInspector initialize(ObjectInspector[] arguments) throws UDFArgumentException {
-    checkArgsSize(arguments, 1, 1);
-    checkArgPrimitive(arguments, 0);
-    if (((PrimitiveObjectInspector) arguments[0]).getPrimitiveCategory() != PrimitiveCategory.STRING) {
-      throw new UDFArgumentException("argument 0 requires to be string rather than " + arguments[0].getTypeName());
-    }
-    soi = (StringObjectInspector) arguments[0];
-    return PrimitiveObjectInspectorFactory.javaStringObjectInspector;
-  }
-
-  @Override
-  public Object evaluate(DeferredObject[] arguments) throws HiveException {
-    Object arg = arguments[0].get();
-    if (arg == null) {
-      return null;
-    }
-    return soi.getPrimitiveJavaObject(arg).toUpperCase(Locale.ROOT);
-  }
-
-  @Override
-  public String getDisplayString(String[] children) {
-    return "upper";
-  }
-}
-```
-
-打包项目为 JAR 文件。
-
-## 上传JAR文件到Volume中
-
-将打包好的 JAR 文件上传至云器 Lakehouse 中创建的 External Volume 中。
-
-首先，创建CONNECTION对象用于连接您已有的对象存储地址。
-
-```SQL
---创建指向对象存储的服务连接定义
-CREATE OR REPLACE STORAGE CONNECTION  qn_hz_bucket_ramrole
-    TYPE oss
-    REGION = 'cn-hangzhou'
-    ROLE_ARN = 'acs:ram::1875653xxxxx:role/czudfrole'
-    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com';
-```
-
-其次，创建EXTERNAL VOLUME对象MOUNT对象存储的指定路径。
-
-```SQL
---创建External Volume
-CREATE EXTERNAL VOLUME qn_hz_bucket_vol
-    location 'oss://qn-hz-bucket/'
-    using connection qn_hz_bucket_ramrole
-    directory = (
-        enable=true,
-        auto_refresh=false
-    )
-recursive=true;
-```
-
-最后使用本地 JDBC 客户端，连接工作空间并在本地客户端中使用 PUT 命令上传 JAR 文件（注：Studio Web-UI 的 SQL 编辑器中不支持使用 PUT 命令上传本地文件）。
-
-```SQL
---上传打包后的UDF JAR
-PUT '/Users/Downloads/upper.jar' TO  VOLUME qn_hz_bucket_vol FILE 'upper.jar';
-
---查看上传的文件
-SHOW VOLUME DIRECTORY qn_hz_bucket_vol;
-
-relative_path                                   url                                                                size last_modified_time  
------------------------------------------------ ------------------------------------------------------------------ ---- ------------------- 
-data_parquet/data.csv                           oss://qn-hz-bucket/data_parquet/data.csv                           34   2024-05-29 17:03:25 
-data_parquet/lakehouse_region_part00001.parquet oss://qn-hz-bucket/data_parquet/lakehouse_region_part00001.parquet 2472 2024-05-24 00:39:08 
-upper.jar                                       oss://qn-hz-bucket/upper.jar                                       3161 2024-05-29 23:11:49 
-```
-
-您也可以指定内部volume。虽然您可以使用内部 Volume，但是您在创建 API CONNECTION 中的 code bucket 参数必须填写外部地址。
-
-* **User Volume 格式地址**:`volume:user://~/upper.jar`
-  * `user` 表示使用 User Volume 协议。
-
-  * `~` 表示当前用户，为固定值。
-
-  * `upper.jar` 表示目标文件名。
-* **Table Volume 格式地址**`volume:table://table_name/upper.jar`
-  * `table` 表示使用 Table Volume 协议。
-  * `table_name` 表示表名，需根据实际情况填写。
-  * `upper.jar` 表示目标文件名。
-
-## 创建External Function
-
-首先，创建函数计算服务Connection对象。
-
-```SQL
-create api connection qn_hz_fc_connection
-type cloud_function 
-with properties ( 
-    'cloud_function.provider' = 'aliyun', 
-    'cloud_function.region' = 'cn-hangzhou', 
-    'cloud_function.role_arn' = 'acs:ram::1875653611111111:role/czudfrole', 
-    'cloud_function.namespace' = 'default', 
-    'cloud_function.code_bucket' = 'qn-hz-bucket'
-);
-```
-
-其次，创建External Function，使用前面定义的Volume对象以读取JAR文件，使用已经定义的函数计算连接的CONNECTION对象用于调用函数计算服务创建一一对应的函数。
-
-```SQL
-create external function public.upper_udf 
-as 'com.example.GenericUdfUpper' 
-USING FILE 'volume://qn_hz_bucket_vol/upper.jar'
-connection qn_hz_fc_connection
-with properties ( 
-         'remote.udf.api' = 'java8.hive2.v0',
-          'remote.udf.protocol' = 'http.arrow.v0' 
-);
-```
-
-## 测试运行
-
-借助测试数据或表数据测试运行UDF。
-
-```SQL
---测试运行UDF
-select public.upper_udf('hello') as upper;
-select public.upper_udf(product_id) from product_grossing limit 50;
-```
-
-具备阿里云控制台访问权限的用户，此时可以登录到阿里云函数计算控制台查看到CREATE EXTERNAL FUNCTION命令执行成功后，云器Lakehouse将自动创建函数以执行自定义函数。
-
-执行 DROP FUNCTION public.upper_udf; 命令删除函数的同时，Lakehouse 平台将同步删除云服务商的对应函数。
-
-# UDAF
-
-支持基于 Hive 2.x UDAF 规范开发函数, 可使用 [GenericUDAFResolver](https://github.com/apache/hive/blob/branch-2.3/ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDAFResolver.java) 和 [GenericUDAFEvaluator](https://github.com/apache/hive/blob/branch-2.3/ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDAFEvaluator.java) 开发 UDAF;
-
-UDAF 函数运行环境：
-
-Java: 1.8 版本 (JDK 发行版由云厂商的函数计算服务运行环境提供)。
-
-创建MAVEN项目，在pom.xml添加依赖。
-
-```XML
-<dependency>
-    <groupId>org.apache.hive</groupId>
-    <artifactId>hive-exec</artifactId>
-    <version>2.3.8</version>
-    <scope>provided</scope>
-    <exclusions>
-        <exclusion>
-            <groupId>org.pentaho</groupId>
-            <artifactId>*</artifactId>
-        </exclusion>
-    </exclusions>
-</dependency>
-```
-
-## UDAF 开发
-
-基于 GenericUDAFResolver 和 GenericUDAFEvalutor 编写 UDAF代码。
-
-```SQL
-package com.example;
-
-import org.apache.hadoop.hive.ql.exec.UDFArgumentTypeException;
-import org.apache.hadoop.hive.ql.metadata.HiveException;
-import org.apache.hadoop.hive.ql.parse.SemanticException;
-import org.apache.hadoop.hive.ql.udf.generic.AbstractGenericUDAFResolver;
-import org.apache.hadoop.hive.ql.udf.generic.GenericUDAFEvaluator;
-import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspector;
-import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector;
-import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector.PrimitiveCategory;
-import org.apache.hadoop.hive.serde2.objectinspector.primitive.IntObjectInspector;
-import org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory;
-import org.apache.hadoop.hive.serde2.typeinfo.PrimitiveTypeInfo;
-import org.apache.hadoop.hive.serde2.typeinfo.TypeInfo;
-
-public class sumint extends AbstractGenericUDAFResolver {
-
-    @Override
-    public GenericUDAFEvaluator getEvaluator(TypeInfo[] info) throws SemanticException {

-## 上传JAR文件到Volume中
-
-编译打包为 JAR，上传到用户指定的对象存储位置或 Lakehouse Volume 对象中。
-
-```SQL
---上传打包后的UDF JAR
-PUT '/Users/Downloads/sumint.jar' TO  VOLUME qn_hz_bucket_vol FILE 'sumint.jar';
-
---查看上传的文件
-SHOW VOLUME DIRECTORY qn_hz_bucket_vol;
-
-relative_path url                           size last_modified_time  
-------------- ----------------------------- ---- ------------------- 
-upper.jar     oss://qn-hz-bucket/upper.jar  3161 2024-05-29 23:11:49 
-sumint.jar    oss://qn-hz-bucket/sumint.jar 1022 2024-05-30 01:10:28 
-```
-
-## 创建External Function
-
-1.  创建与函数计算服务连接的 Connection 对象（参见 UDF 中的介绍）
-2. 在 LakeHouse 系统中创建外部函数
-
-UDAF的 External Function创建语法说明：
-
-```SQL
-CREATE EXTERNAL FUNCTION public.<funcName>
-    AS '<className>'
-    USING FILE 'oss://<bucket>/<pathToJar>'
-    CONNECTION <connectionName>
-    WITH PROPERTIES (
-        'remote.udf.api' = 'java8.hive2.v0', 
-        'remote.udf.category' = 'AGGREGATOR');
-```
-
-参数说明:
-
-1. functionName: 可使用任意合法标识符, 比如 my\_agg
-2. className: 填写第 1 步中开发的 GenericUDAFResolver 的完整类名, 比如 com.example.GenericUDAFSum;
-3. bucket 和 pathToJar: 填写第 2 步上传到 OSS 的存储桶和对象路径;
-4. connectionName: 使用第 3 步创建的 connection 的名字, 比如 udf\_deploy\_0317;
-5. 最后两个 PROPERTIES 保持原样即可;
-
-示例如下：
-
-```SQL
---创建External Function
-create external function public.sumint
-as 'com.example.sumint' 
-USING FILE 'volume://qn_hz_bucket_vol/sumint.jar'
-connection qn_hz_fc_connection
-with properties ( 
-         'remote.udf.api' = 'java8.hive2.v0',
-         'remote.udf.category' = 'AGGREGATOR'
-);
-```
-
-## 测试运行
-
-借助测试数据或表数据测试运行 UDF。注：当前需要通过 cz.sql.remote.udf.enabled 参数开启远程函数访问。
-
-```SQL
---测试运行UDF
-set cz.sql.remote.udf.enabled = true;
-select public.sumint(amount) from product_grossing;
-```
-
-# UDTF
-
-## UDTF 开发
-
-支持继承org.apache.hadoop.hive.ql.udf.generic.GenericUDTF进行UDTF开发。UDTF需要实现initialize, process, close三个方法。UDTF首先会调用initialize方法，此方法返回UDTF的返回行的信息（返回个数，类型）。初始化完成后，会调用process方法，对传入的参数进行处理，可以通过forword()方法把结果返回。最后close()方法调用，对需要清理的方法进行清理。
-
-编写UDTF代码，示例如下：
-
-```Java
-package com.example;
-
-import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
-import org.apache.hadoop.hive.ql.metadata.HiveException;
-import org.apache.hadoop.hive.ql.udf.generic.GenericUDTF;

-# FLOAT
-32位二进制浮点型（FLOAT）是一种用于存储实数的数值数据类型，其精度和范围有限。在数据库中，FLOAT类型通常用于存储带有小数部分的数值。
-
-## 语法
-```
-FLOAT
-```
-
-## 示例
-```
--- 使用 FLOAT 类型存储正数
-SELECT 1.5F;
-
--- 使用 FLOAT 类型存储负数
-SELECT -3.2F;
-
--- 将其他数值类型转换为 FLOAT 类型
-SELECT CAST(6.1 AS FLOAT);
-
--- 在 SELECT 语句中使用 FLOAT 类型
-SELECT FLOAT(salary) FROM employees;
-
--- 在 WHERE 子句中使用 FLOAT 类型进行条件筛选
-SELECT * FROM products WHERE price < 50.0F;
-```
-
-## 注意事项
-1. FLOAT 类型的数值可能会有精度损失，因此在需要高精度计算的场景下，建议使用 DECIMAL 或 NUMERIC 类型。
-2. 在比较 FLOAT 类型的数值时，应注意其精度和舍入误差，避免因精度问题导致的比较错误。
-3. 在使用 FLOAT 类型时，建议明确指定数值的精度和小数位数，以避免因隐式类型转换导致的意外结果。
-
-## 总结
-32位二进制浮点型（FLOAT）是一种用于存储实数的数值数据类型，适用于存储带有小数部分的数值。在使用时，应注意精度损失、舍入误差和类型转换等问题，确保数据的准确性和可靠性。

-# 使用 Zettapark 扩展客户特征的特征工程
-
-## 概述
-
-本教程展示了如何使用[Zettapark](ZettaparkQuickStart.md)对[TPCH 表](sample-data-using.md)进行特征工程代码的编写。通过本教程，我们将展示如何构建派生（聚合和转换）特征，以支持多个机器学习任务。例如，您可以构建以下内容：
-
-**客户细分/流失预测**：
-
-* 特征数据：每位客户的总消费金额、订单数量、平均订单金额、客户人口统计信息（例如市场细分、账户余额）以及地理信息（国家/地区）。
-* 方法：对订单进行聚合，并通过与客户、国家和地区表连接进行丰富。
-
-**销售预测**：
-
-* 特征数据：基于时间的度量，如总销售额、平均销售额、订单频率以及每位客户或每个地区的趋势。
-* 方法：对订单和行项目细节进行聚合。
-
-**供应商绩效/产品销售分析**：
-
-* 特征数据：对于供应商，包括总可用数量、总供应成本和平均供应成本；对于产品，包括销售金额和频率，可能需要使用`CASE WHEN`对产品类型进行分类转换。
-* 方法：对 partsupp、lineitem 和 part 表进行分组和聚合，并使用`CASE WHEN`转换进行领域特定的分类。
-
-您可以从[GitHub 存储库获取源代码（Jupyter Notebook ipynb 文件）](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/Zettapark/FeatureEngineeringForExpandingCustomerFeatureswithZettapark.ipynb)。

-### 1. 客户销售聚合
-
-* **功能**：
-  此代码按客户键对订单表进行分组，并聚合关键指标，例如每位客户的总销售额（订单总额之和）、订单数量和平均订单价值。这些聚合指标随后被重命名，并与客户表连接，将客户的个人信息（姓名、地址、账户余额等）与其购买行为集成。
-
-* **目标**：
-  构建客户级销售指标数据集，可用于进一步分析或预测建模任务，如客户细分或流失预测。
-
-```python

-* **销售预测**：订单日期（源自订单/行项目）的时间维度可能会在后续步骤中与聚合后的销售数据结合，以预测未来的销售情况。
-* **供应商绩效分析/产品销售预测**：通过计算聚合后的供应商指标（使用 partsupp 和供应商表）以及产品绩效（源自行项目和产品），可以构建模型来预测供应商的可靠性或评估产品销售潜力。
-
-### 特征工程细节
-
-* **聚合**：使用 groupBy 和聚合函数（sum、count、avg）从事务表（如订单）中计算指标（总销售额、订单数量等）。
-* **丰富和连接**：集成关联信息（将客户与国家和地区表连接，将 partsupp 与供应商表连接），以附加人口统计或地理信息。
-* **转换（CASE WHEN**）：使用 when 函数进行条件转换，例如将产品类型或市场细分编码为数值代码。这在机器学习模型需要数值输入时至关重要。
-* **数据清理**：应用 na.fill(0) 或其他插补方法处理缺失值，确保机器学习数据集的完整性。
-
-此代码提供了一个起点。根据具体的机器学习场景，您可能需要添加基于时间的窗口函数、更细粒度的特征拆分或特定领域的转换。祝您在探索这些特征和构建模型时一切顺利！

-# GET 命令
-
-## 概述
-
-GET 命令用于从云器 Lakehouse 的数据湖 Volume 对象中下载文件到客户端本地路径。通过该命令，用户可以轻松地将数据从云端同步到本地环境，以便进行进一步的分析和处理。要执行 GET 命令，您可以使用 [sqlline](connect-with-cli.md) 工具或 [数据库管理工具](eco_integration/dbeaver-lakehouse.md)。该命令暂不支持在 Studio 中运行。
-
-## 使用场景
-
-* 数据分析：将数据文件从云端下载到本地进行分析和挖掘。
-* 数据迁移：将数据从云端迁移到本地存储，以便在本地进行备份或迁移到其他云平台。
-* 数据恢复：从云端恢复丢失或损坏的数据到本地。
-
-## 语法
-
-```
-GET 
-    [ VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME ]
-    [ FILE 'file' ] 
-    TO 'local_path'
-    [ option_key = option_value ] ...
-```
-
-## 参数说明
-
-* `VOLUME/TABLE VOLUME/USER VOLUME`：分别指将外部 Volume、TABLE VOLUME 和 USER VOLUME 中的数据下载到本地。具体使用方式参考 [COPY INTO导出](<COPY-INTO-Location.md>)。
-* `FILE`：指定要下载的文件。
-* `local_path`：文件下载到本地的目标路径，其格式根据不同操作系统有所区别。
-
-
-## 示例
-
-1. 将表中数据下载到本地
-
-   ```
-    --将数据导出到内部user volume中
-    COPY INTO USER VOLUME SUBDIRECTORY 'tmp/' FROM TABLE mytable  file_format = (type = CSV);;
-    
-    -- 查看导出的文件
-    SHOW  USER VOLUME DIRECTORY;
-   +-------------------+------------------------------------------------------------------------------------------------------------+------+---------------------+
-   |   relative_path   |                                                    url                                                     | size | last_modified_time  |
-   +-------------------+------------------------------------------------------------------------------------------------------------+------+---------------------+
-   | tmp/part00001.csv | oss://xxxx/tmp/part00001.csv | 5    | 2024-11-14 19:44:37 |
-   +-------------------+------------------------------------------------------------------------------------------------------------+------+---------------------+
-
-    --下载文件
-    GET USER VOLUME FILE 'tmp/part00001.csv' TO  './';
-    --删除volume中文件，避免占用存储
-    REMOVE USER VOLUME FILE 'tmp/part00001.csv';
-    SHOW USER VOLUME DIRECTORY;
-   +---------------+-----+------+--------------------+
-   | relative_path | url | size | last_modified_time |
-   +---------------+-----+------+--------------------+
-   ```
-
-
-
-## 注意事项
-
-* 从外部 Volume 下载文件会产生对应云账号的对象存储下载费用。
-* GET 命令不能通过 Studio SQL 任务节点执行，但可以通过云器 Lakehouse SQLline 客户端、JDBC 客户端以及 SDK 来执行。

-# GET\_PRESIGNED\_URL 函数
-
-该函数通过输入 Volume 名称、文件的相对路径和有效时间（秒），为 Volume 中的文件生成一个预签名 URL。此功能允许应用程序访问存储在外部 Volume 中的文件。
-
-## 使用场景
-
-以下是几种访问 Volume 中文件的方法：
-
-1. 在 Web 浏览器中直接访问带有一个预签名的 URL（字符串类型）。
-2. 将 Volume 中文件的预签名 URL 发送给远程函数进行处理。
-
-## 注意事项
-
-1. 执行该函数的用户需要对 Volume 对象具有读取 (READ) 权限。
-
-2. 该函数需要从 Volume 本地的元数据系统中获取文件信息（例如 `relative_path`）。请确保刚刚导入的 Volume 对应的文件元数据已经同步到 Lakehouse 元数据系统，或使用以下命令进行刷新：
-
-   ```
-   ALTER VOLUME <volume_name> REFRESH;
-   ```
-
-3. GET\_PRESIGNED\_URL 是一个非确定性函数 (non-deterministic function)，即在给定相同输入值的情况下，每次执行的输出结果可能不同。
-
-## 语法
-
-```
-GET_PRESIGNED_URL(VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME , '<relative_file_path>', [<expiration_time>])
-```
-
-## 参数
-
-* **volume \<volume\_name**>**：`volume` 为固定关键字，表示后面的对象类型为 Volume；`volume_name` 为系统创建的 Volume 名称。
-* **relative\_file\_path**：相对于 Volume 指定位置的文件路径和文件名。可以通过调用 `directory` 函数获取：
-  ```
-  SELECT GET_PRESIGNED_URL(volume <volume_name>, relative_path) AS pre_signed_url
-  FROM DIRECTORY(volume <volume_name>);
-  ```
-* **expiration\_time**：生成的预签名 URL 的有效期，以秒为单位。默认值为 3600 秒（60 分钟）。
-
-## 返回值
-
-一个预签名的 URL（字符串类型）。
-
-## 使用示例
-
-以下是几个使用 GET\_PRESIGNED\_URL 函数的示例：
-
-1. 生成一个有效期为 1 小时的预签名 URL：
-
-   ```
-   SELECT GET_PRESIGNED_URL(volume hz_image_volume, 'example.jpg', 3600) AS pre_signed_url;
-   ```
-
-2. 生成一个默认有效期（1 小时）的预签名 URL：
-
-   ```
-   SELECT GET_PRESIGNED_URL(USER VOLUME, 'pangxie_pic.jpg', 3600) AS pre_signed_url;
-   ```
-
-3. 从目录中获取文件的相对路径，并生成一个预签名 URL：
-
-   ```
-   SELECT GET_PRESIGNED_URL(volume hz_image_volume, relative_path) AS pre_signed_url
-   FROM DIRECTORY(volume hz_image_volume);
-   ```
-
-> 注意：如果生成的 URL 无法访问，可能是因为生成了对象存储的内部链接。可尝试在执行 SQL 前添加以下参数后再次尝试：
->
-> `set cz.sql.function.get.presigned.url.force.external=true;`
->
-> 例如：
->
-> ```
-> SET cz.sql.function.get.presigned.url.force.external=true; 
-> SELECT GET_PRESIGNED_URL(USER VOLUME, 'pangxie_pic.jpg', 3600) AS pre_signed_url;
-> ```
-
-4. 批量获取 USER VOLUME 中图片的预签名 URL
-
-   ```
-    SET cz.sql.function.get.presigned.url.force.external=true;
-    SELECT relative_path,
-    GET_PRESIGNED_URL(USER VOLUME, relative_path, 3600) AS pre_signed_url
-    FROM (
-          SELECT relative_path FROM (LIST USER VOLUME)
-    );
-    ```
-
-通过以上示例，您可以更好地了解如何在不同场景中使用 GET\_PRESIGNED\_URL 函数。请根据您的实际需求调整参数和代码。

-## 功能概述
-
-Hive 存储连接用于访问和管理已有的 Hive 元数据服务。通过配置此连接，您可以：
-
-1. 无缝对接现有的数据仓库基础设施。
-2. 复用已构建的表结构和元数据信息。
-3. 统一管理数据目录，实现跨平台数据资产整合。
-
-这种配置方式特别适合企业在数据平台升级或整合过程中，实现平滑过渡和系统共存。您无需迁移现有数据，即可充分利用两个系统的优势。
-
-## 使用限制
-
-* 使用前请确保 Lakehouse 和 Hive 集群网络已打通。
-* 目前，云器 Lakehouse 的外部 Catalog 功能支持以下外部数据源：
-  * Hive on OSS（阿里云对象存储服务）
-  * Hive on COS（腾讯云对象存储服务）
-  * Hive on S3（AWS对象存储服务）
-  * Hive on GCS（Google云对象存储服务）
-* 同时支持读取和写入。写入格式支持 Parquet、ORC、Text 文件格式。
-
-### 创建外部 Catalog
-
-**创建 Hive Catalog 的步骤**
-
-1.  **创建存储连接**：首先需要创建一个存储连接，用于访问对象存储服务。
-2.  **创建 Catalog Connection**：使用存储连接信息和 Hive Metastore 地址创建 Catalog Connection。
-3.  **创建外部 Catalog**：使用 Catalog Connection 创建外部 Catalog，以便在数据湖中访问外部数据。
-
-#### 创建存储连接
-
-创建存储连接可参考文档 [创建STORAGE CONNECTION](aliyun_storage_connection.md)。
-
-```SQL
-CREATE STORAGE CONNECTION if not exists catalog_storage_oss
-    type OSS
-    ACCESS_ID='LTAIxxxxxxxxxxxx'
-    ACCESS_KEY='T8Gexxxxxxmtxxxxxx'
-    ENDPOINT='oss-cn-hangzhou-internal.aliyuncs.com';
-```
-
-#### 创建 Catalog Connection
-
-```SQL
-CREATE CATALOG CONNECTION if not exists catalog_api_connection
-    type hms
-    hive_metastore_uris='xxx:9083'
-    storage_connection='catalog_storage_oss';

-# 自增列IDENTITY
-
-Lakehouse支持在建表时标识列，将字段定义为自增字段。
-
-配置自增序列。如下建表语句使用自增列，仅支持bigint类型：
-
-```Plain
-CREATE TABLE tablename (
-    id bigint identity
-);
-```
-
-## 语法
-
-```SQL
-IDENTITY[(seed)]
-```
-
-* seed：用于指定表中第一行的起始值。如果不指定，默认起始值为0。

-## 功能概述
-
-`INSERT INTO` 语句用于将数据插入表中。您可以为表中的每个列显式指定值，或者使用 `SELECT` 查询的结果作为插入的数据源。
-
-## 语法结构
-
-```SQL
-INSERT INTO|OVERWRITE [TABLE] table_name 
-[ PARTITION partition_spec] 
-[ (column1, column2, ...)]
-{VALUES(value1 [,...],(value2 [,...]),...) | subquery}
-
-partition_spec ::=
-    partition_column_name = partition_column_val [ , ... ]
-```
-
-## 参数详解
-
-1. **INSERT INTO**：以追加模式插入数据。
-2. **INSERT OVERWRITE**：重写目标表或目标表的某些分区。
-   * 对于分区表，将覆盖指定分区的数据。
-   * 对于非分区表，将覆盖整个表的数据。
-3. **TABLE**：（可选）关键字，用于指定目标表。
-4. **partition\_spec**：（可选）分区规范，用于指定插入数据的分区。
-   * 静态分区：直接指定分区列的值，例如 `PARTITION (dt='shanghai')`。
-   * 动态分区：系统根据 `VALUES` 或 `SELECT` 语句的值自动映射到相应分区。
-   * 如果未指定分区规范，系统将根据分区列的值自动选择分区。
-5. **column\_list**：指定要插入数据的列，确保输入查询的列顺序与表中的列顺序相匹配。
-
-## 使用指南
-
-* **数据类型匹配**：确保插入的数据类型与表定义中的列类型相匹配。
-
-* **查询结果匹配**：使用 `SELECT` 语句插入数据时，查询返回的列数量和顺序应与目标表的列相匹配。
-
-* **分区规范**：在分区表中插入数据时，如果未指定分区规范，系统将根据分区列的值自动选择分区。确保插入的数据中包含有效的分区值。
-
-* **INSERT OVERWRITE**：使用此语句插入数据时，确保目标表或分区存在，否则操作将失败。
-
-* **数据检查**：执行插入操作前，检查数据类型和列数量是否与目标表匹配，以避免数据插入错误。**特别注意的是，Apache Hive要求分区列是最后一个位置。没有这种强制要求，因此加列的时候特别注意：按照原来Hive方式加列可能会将列加到最后一个位置，所以加列的时候必须指定位置。否则会造成数据错误。**
-
-* **自动分区处理**：当使用分区字段为函数的表时，无需指定 `PARTITION` 子句，系统会自动根据函数返回值处理分区。
-
-* **大量数据导入**：在lakehouse环境中，不推荐使用 `INSERT INTO...VALUES` 方式导入大量数据，这种方式更适合测试场景。对于大量数据导入，请参阅[数据导入指南](data-load-summary.md)。
-
-## 使用示例
-
-**普通表插入**
-假设`test` 表包含两个列`c1`, `c2`。
-
-1. 向`test`表中导入一行数据
-
-```
-INSERT INTO test VALUES (1, 2);
-INSERT INTO test (c1, c2) VALUES (1, 2);
-INSERT INTO test (c1) VALUES (1);
-```
-
-其中第一条、第二条语句是一样的效果。在不指定目标列时，使用表中的列顺序来作为默认的目标列。 第三条语句未指定`c2`则使用null来填充，如果`c2`列有默认值则使用默认值填充。
-
-2. 向`test`表中一次性导入多行数据
-
-```
-INSERT INTO test VALUES (3, 5), (5, 5 + 2);
-INSERT INTO test (c1, c2) VALUES (6, 7), (6, 7* 2);
-INSERT INTO test (c1) VALUES (1), (3);
-```
-
-其中第一条、第二条语句效果一样，向`test`表中一次性导入两条数据。第三条语句未指定`c2`则使用null来填充，如果有默认值则使用默认值，向`test`表中导入两条数据。
-
-3. 向 `test` 表中导入一个查询语句结果
-
-```
-INSERT INTO test SELECT * FROM test2;
-INSERT INTO test (c1, c2) SELECT * from test2;
-```
-
-4. 分区表插入数据
-
-```SQL
--- 创建分区表
-CREATE TABLE sales (
-  id BIGINT,
-  name VARCHAR(64),
-  dt STRING
-)
-PARTITIONED BY (dt);
-
--- 插入单行数据
-INSERT INTO sales VALUES (1001, 'Alice', '2021-01-01');
-
--- 插入多行数据
-INSERT INTO sales VALUES (1002, 'Bob', '2021-01-02'), (1003, 'Charlie', '2021-01-03');
-
--- 指定分区插入数据
-INSERT INTO sales PARTITION (dt='2021-01-04') (id, name) VALUES (1004, 'David');
-
--- 使用 SELECT 语句插入数据
-INSERT INTO sales SELECT * FROM sales_temp;
-```
-
-5. 插入数据时指定列顺序
-
-```SQL
--- 假设表结构为 (id, name, dt)
-CREATE TABLE sales (id BIGINT, name VARCHAR(64), dt STRING);
-
--- 插入数据时仅指定 id 和 name 列。未指定的列则会显示null
-INSERT INTO sales (id, name) VALUES (1005, 'Eve');
-+------+------+----+
-|  id  | name | dt |
-+------+------+----+
-| 1005 | Eve  |    |
-+------+------+----+
-```
-
-6. 使用INSERT OVERWRITE插入数据
-
-```SQL
--- 创建分区表
-CREATE TABLE sales (
-  id BIGINT,
-  name VARCHAR(64),
-  dt STRING
-)
-PARTITIONED BY (dt);
-
--- 插入单行数据
-INSERT OVERWRITE sales VALUES (1001, 'Alice', '2021-08-01');
-
--- 插入多行数据
-INSERT OVERWRITE sales VALUES (1002, 'Bob', '2021-08-02'), (1003, 'Charlie', '2021-08-03');
-
--- 指定分区插入数据
-INSERT OVERWRITE sales PARTITION (dt='2021-08-04') VALUES (1004, 'David', '2021-08-04');
-
--- 使用查询结果插入数据
-INSERT OVERWRITE sales SELECT * FROM sales_temp;
-```
-
-7. 插入不同的数据类型
-
-```
-CREATE TABLE lakehouse_datatype(
-  `c_bigint` bigint,
-  `c_boolean` boolean,
-  `c_binary` binary,
-  `c_char` char(1),
-  `c_date` date,

-# 将数据从阿里云数据湖摄取到云器 Lakehouse 的三层数据仓库中
-
-## 关于三层数据仓库（3 Layer Data Warehouse）
-
-在现代数据湖仓架构中，三层数据仓库（3 Layer Data Warehouse）通常分为Bronze层、Silver层和Gold层。这种架构提供了一种系统化的方法来管理不同状态的数据，从原始数据到高质量数据。
-
-### 1. Bronze层（原始数据层）
-
-Bronze层是数据仓库的最底层，用于存储从各种数据源提取的原始数据。这些数据未经处理，保留了数据的原始形式。
-
-**特点**：
-
-* **数据状态**：原始、未经处理的数据。
-* **数据来源**：各种数据源（数据库、日志、文件等）。
-* **目的**：提供原始数据的备份和数据追溯，确保数据的完整性和可审计性。
-
-### 2. Silver层（清洗和转换层）
-
-Silver 层用于存储经过清洗和转换的数据。这一层的数据经过 ETL（Extract, Transform, Load）流程处理，去除了噪声和冗余，转化为结构化和标准化的数据格式。
-
-**特点**：
-
-* **数据状态**：经过清洗和标准化处理的数据。
-* **数据操作**：清洗、去重、数据转换和整合。
-* **目的**：提供高质量、结构化的数据，以便进一步处理和分析。
-
-### 3. Gold层（业务信息层）
-
-Gold 层是面向分析和业务的重要数据层，存储经过进一步优化和聚合的数据。这一层的数据通常支持商业智能（BI）、数据分析和报告等应用。
-
-**特点**：
-
-* **数据状态**：高质量、聚合和优化过的数据。
-* **数据操作**：数据聚合、多维分析、数据建模。
-* **目的**：支持数据分析、商业智能和决策支持，提供优化的数据视图。
-
-### 三层数据仓库架构的优势
-
-* **数据管理效率**：分层存储和处理数据，使得管理和维护更加便捷。
-* **数据质量提升**：清洗和转换层保证了数据的一致性和准确性。
-* **高效数据访问**：业务信息层经过优化的数据结构，提升了查询性能。
-* **灵活性强**：适应不同的业务需求，支持各种数据源的整合和处理。
-
-通过这种三层架构，企业可以更有效地管理和分析数据，确保数据从采集到分析的各个阶段都得到妥善处理和优化。
-
-### 需要什么
-
-* [云器Lakehouse](https://www.yunqi.tech/)账户
-* 本指南的[Github代码库](https://github.com/yunqiqiliang/clickzetta_quickstart/tree/main/QuickStarts_Data_from_Alicloud_Datalake_to_3Layer_Clickzetta_Data_Warehouse)
-* 访问阿里云OSS的AK信息
-
-## 基于云器Lakehouse的实现方案
-
-本方案是基于云器 Lakehouse 创建一个多层数据仓库架构，其中有三层：用于数据提取的 Bronze 层、用于清理和转换数据的 Silver 层以及用于业务级聚合和数据修改的 Gold 层。
-
-^
-
-:-: ![](.topwrite/assets/image_1736762188020.png =819)
-
-###
-
-### Bronze层
-
-Bronze层专注于从阿里云对象存储OSS到云器Lakehouse的数据摄取。这是通过创建数据湖 Connection 和 External Volume，以及 Lakehouse Pipe、Table Stream 来完成的，该阶段在 External Volume 中指定阿里云 OSS 中数据的位置。使用External Volume，可以使用Lakehouse Pipe自动将数据实时摄入到Lakehouse的表中。
-
-最后，为每个表创建一个 Table Stream，以跟踪和保存对表所做的任何更改。这些流可用于识别 Bronze 层表中的更改并对 Silver 层中的相应表进行更新。
-
-### Silver层
-
-Silver层专注于数据清理和转换。它使用来自Bronze层的原始数据，并对其进行转换以满足公司的需求。这些转换包括清理缺失或异常值、数据验证以及删除未使用或不重要的数据。
-
-#### 客户数据清洗与转换

-| 转型     | 细节                      |
-| ------ | ----------------------- |
-| 电子邮件验证 | 确保电子邮件不为空               |
-| 客户类型   | 将客户类型标准化为“常规”、“高级”或“未知” |
-| 年龄验证   | 确保年龄在 18 至 120 岁之间      |
-| 性别标准化  | 将性别分类为“男”、“女”或“其他”      |
-| 总购买量验证 | 确保总购买量是一个数字，如果无效则默认为 0  |
-
-#### 产品数据清洗与转换
-
-| 转型     | 细节             |
-| ------ | -------------- |
-| 价格验证   | 确保价格为正数        |
-| 库存数量验证 | 确保库存数量非负       |
-| 评级验证   | 确保评分在 0 到 5 之间 |
-
-#### 订单数据清洗与转换
-
-| 转型       | 细节          |
-| -------- | ----------- |
-| 金额验证     | 确保交易金额大于 0  |
-| 交易 ID 验证 | 确保交易 ID 不为空 |
-
-### Gold层
-
-Gold层旨在利用Silver层的转换数据来创建可用于业务分析的动态表。例如，DT\_RegionAnalysis是一个结合所有 3 个表的统一数据视图，用于分析不同地区的销售业绩并确定销售额最好的地区。
-除了本项目所展示的简单动态表之外，还可以在Gold层进行许多额外的分析。

-    put_file_into_volume(f"{file_path}/order/raw_order_{current_time}.csv","VOLUME_FOR_RAW_ORDER")
-```
-
-第一次调用生成产品、客户、订单的数据。第二次及更多次调用，只需要生成订单新数据即可。可以多次执行上传多个订单文件。
-注意每次 PUT 到 Volume 上的文件被 Pipe 消费后，会被自动删除。

-# 连接MindsDB实现基于ML和LLM的数据分析
-
-步骤概述：
-
-1. 在云器Lakehouse的“数据源”里增加MySQL类型的数据源，通过MySQL协议连接到[MindsDB](mindsdb.md)。
-2. 在云器Lakehouse中新建“JDBC脚本”任务类型，数据源选择在第一步新建的MindsDB数据源。
-3. 这样，就可以在云器Lakehouse中使用MySQL语法来操作和管理MindsDB，并对云器Lakehouse中的数据，通过MindsDB管理的模型（包括传统机器学习模型和LLM）进行各种预测分析。
-4. 与SQL任务一样，可以直接对JDBC任务进行周期调度和运维，并通过设置任务依赖实现与其他任务的工作流编排。
-
-## 新建MindsDB连接
-
-新建连接前，请确保您的MindsDB已开启MySQL服务端口47335。

-# JOIN
-
-Join 是指在 SQL 语句中使用 JOIN 子句将两个或多个表的数据根据某些条件进行合并的操作。它可以让您从不同的数据源中获取相关信息，并且可以在合并之前或之后对数据进行一些转换或处理。Join 的语法如下：
-
-```SQL
-left_table_reference { 
-[ join_type ] JOIN right_table_reference join_criteria |
- NATURAL  JOIN right_table_reference | 
- CROSS JOIN right_table_reference } 
- --join类型
-join_type::= 
-     { [ INNER ] | LEFT [ OUTER ] | [ LEFT ] SEMI | RIGHT [ OUTER ] | FULL [ OUTER ] | [ LEFT ] ANTI | CROSS } 
---join条件
-join_criteria::=
-     { ON boolean_expression | USING ( column_name [, ...] ) }
-```
-
-其中，`left_table_reference` 是指 JOIN 的左表，`right_table_reference` 是指 JOIN 的右表，`join_type` 是指 JOIN 的类型，`join_criteria` 是指 JOIN 的条件。
-
-## Join的类型
-
-Join 的类型有以下几种：
-
-* **INNER JOIN**：返回两个表中满足 JOIN 条件的数据行，也就是两个表的交集。这是默认的 JOIN 类型。
-* **LEFT \[OUTER] JOIN**：返回左表的所有数据行，以及右表中满足 JOIN 条件的数据行，如果右表中没有匹配的数据行，则用 NULL 填充。这也叫做左外连接。
-* **RIGHT \[OUTER] JOIN**：返回右表的所有数据行，以及左表中满足 JOIN 条件的数据行，如果左表中没有匹配的数据行，则用 NULL 填充。这也叫做右外连接。
-* **FULL \[OUTER] JOIN**：返回两个表的所有数据行，如果某个表中没有匹配的数据行，则用 NULL 填充。这也叫做全外连接。
-* \[**LEFT] SEMI JOIN**：返回左表中满足 JOIN 条件的数据行，不返回右表的数据。这也叫做左半连接。
-* \[**LEFT] ANTI JOIN**：返回左表中不满足 JOIN 条件的数据行，不返回右表的数据。这也叫做左反连接。
-* **CROSS JOIN**：返回两个表的笛卡尔积，也就是两个表所有可能的组合。
-* **NATURAL JOIN**：根据两个表中同名的列进行隐式的等值连接，不需要指定 JOIN 条件。
-
-## Join的条件
-
-Join 的条件有以下两种：
-
-* **ON boolean_expression**：指定一个返回布尔值的表达式，用来判断两个表的数据行是否匹配。如果结果为真，则认为匹配。JOIN 条件不支持子查询。
-* **USING (column_name** [, …])：指定一个或多个列名，用来进行等值连接。这些列名必须同时存在于两个表中。JOIN 条件不支持子查询。
-
-## Join 的使用示例
-
-以下是一些使用 JOIN 的 SQL 语句的示例，以及它们的输出结果。假设我们有以下两个表：
-
-```SQL
-create table students(name string,class string);
-INSERT INTO students (name, class) VALUES
-('Alice', 'A'),
-('Bob', 'B'),
-('Carol', 'A'),
-('David', 'C');
-create table scores(name string,score int);
-INSERT INTO scores (name, score) VALUES
-('Alice', 90),
-('Bob', 80),
-('Carol', 85),
-('David', 95);
-```
-
-### INNER JOIN

-# JSON数据格式简介
-
-JSON（JavaScript Object Notation）是一种轻量级、易于阅读和编写的半结构化数据格式。它基于JavaScript的一个子集，但是JSON是独立于语言的，许多编程语言都有JSON数据格式的解析和生成代码。JSON格式使用文本表示简单的数据结构，如对象、数组、字符串、数字和布尔值。JSON格式具有良好的可读性和简洁性，使其成为理想的数据交换格式。
-
-# LakeHouse中的JSON类型
-
-在LakeHouse中，JSON类型的数据可以高效地存储和查询。JSON数据在LakeHouse中会被解析，并根据数据的实际结构进行优化存储。以下是LakeHouse中JSON类型的一些特点：
-
-1. 查询性能：使用JSON类型相比于String类型在查询性能上有明显优势，因为LakeHouse会对JSON数据进行列裁剪，减少不必要的数据扫描。
-2. 数据重排：解析过程中，JSON对象的数据可能会被重新排序，因此输入和输出的JSON数据可能在键的顺序上不一致。
-3. 数字解析：解析JSON数字时，LakeHouse会优先尝试将其解析为bigint类型。如果数字超出bigint的范围，则会将其解析为double类型。需要注意的是，double类型可能会有精度损失。
-4. 错误处理：使用函数解析JSON数据时，LakeHouse会进行校验。对于非法的JSON字符串，会返回NULL值；而在声明JSON常量时，非法的JSON字符串会导致错误。
-
-此外，LakeHouse在写入过程中会根据实际的JSON Schema，将出现频次高的字段按照列存储的方式存储，以提高存储和查询效率。例如：
-
-```SQL
-CREATE TABLE json_table AS
-SELECT  parse_json(s) as j
-FROM VALUES
-('{"id": 1, "value": "200"}'),
-('{"id": 2, "value": "300"}'),
-('{"id": 3, "value": "400", "extra": 1}'),
-('{"value": "100"}') as t(s);
-```
-
-1. 对于上面的数据，LakeHouse 检测出 id 和 value 出现频次高，分别适合用 bigint 和 string 类型列式存储，则会在内部以类似 struct\<id:bigint, value:string> 的结构存储。在后续的查询过程中，如果只读取id字段且转换为bigint，如`SELECT json_extract_bigint(j, '$.id')`，则可以直接按列读取 id 字段，并消除类型转换的开销。
-2. 对于出现频次低的 extra 字段，则保留 json 结构且用更加紧凑的表示存储，避免产生过于稀疏的数据。
-
-**限制**
-
-* 不支持对JSON类型的比较操作，也不支持对JSON类型进行`ORDER BY`、`GROUP BY`或作为`JOIN`的key等。
-* 不支持作为cluster key、primary key、partition key
-* JSON字符串最大长度为16 MB。批量、实时导入时对字段进行长度校验。如果您导入数据时有大于16MB的数据您可以修改表的Properties来修改如下将json长度设置为32MB
-```
-ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.json.bytes"="33554432");
-```
-
-
-## 创建JSON列的表
-
-要创建包含JSON类型列的表，可以使用以下SQL语句：
-
-```sql
-CREATE TABLE json_example
-(
-    id bigint,
-    data json
-);
-```
-
-## 构建JSON数据
-
-### JSON常量
-
-在SQL查询中，可以使用JSON常量来表示JSON数据。例如：
-
-```sql
-SELECT
-JSON 'null',
-JSON '1',
-JSON '3.14',
-JSON 'true',
-JSON 'false',
-JSON '{"id":11,"name":"Lakehouse"}',
-JSON '[0, 1]';
-
--- !query output
-+-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
-| JSON 'null' | JSON '1' | JSON '3.14' | JSON 'true' | JSON 'false' | JSON '{"id":11,"name":"Lakehouse"}' | JSON '[0, 1]' |
-+-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
-| null        | 1        | 3.14        | true        | false        | {"id":11,"name":"Lakehouse"}        | [0,1]         |
-+-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
-```
-
-
-### 语法
-
-```SQL
---键名访问JSON对象中的字段
-json_column['key']['key']...
---通过索引访问JSON数组中的元素
-json_array[index]
-```
-
-**参数说明**
-
-* json\_column:表示一个JSON字段，类型为JSON对象。通过键名（`key`），指定为字符串，来定位并检索JSON对象内的特定数据字段。使用单个方括号`[]`可以访问对象的一级字段；而嵌套使用双方括号`[][]`则能够深入检索对象的二级或更深层次的字段。
-* json\_array:数组类型的JSON，用来根据index访问 JSON array的元素，起始值为0

-                 as t(s);
-```
-
-取出json数组中的元素
-
-```SQL
-SELECT parse_json(s)['phoneNumbers'][0]['number'] as j
-      FROM VALUES ('{ "firstName": "John", "lastName": "doe", "age": 26, "address": { "streetAddress": "naist street", "city": "Nara", "postalCode": "630-0192" }, "phoneNumbers": [ { "type": "iPhone", "number": "0123-4567-8888" }, { "type": "home", "number": "0123-4567-8910", "extra": [] } ] }'),
-                  ('{ "firstName": "Ada", "lastName": "doe", "age": 20, "address": { "streetAddress": "naist street", "city": "Nara", "postalCode": "630-0192" }, "address2": {"city": "NewYork"}, "phoneNumbers": [ { "type": "iPhone", "number": "0123-4567-8888" }, { "type": "home", "number": "0123-4567-8910", "extra": [1,2,3] } ] }')
-                 as t(s);
-```
-
-
-
-### 使用函数
-
-### 使用函数(将STRING格式的JSON转化为字符串)
-
-`parse_json`函数可以将String类型的JSON字符串解析为JSON类型。例如：
-
-```SQL
-SELECT parse_json(s) is null, parse_json(s)
-FROM VALUES ('null'),
-            ('1'),
-            ('3.14'),
-            ('true'),
-            ('false'),
-            ('{"id":11,"name":"Lakehouse"}'),
-            ('[0, 1]'),
-            (''),
-            ('invalid') as t(s);
-+-------------------------+------------------------------+
-| (parse_json(s)) IS NULL |        parse_json(s)         |
-+-------------------------+------------------------------+
-| false                   | null                         |
-| false                   | 1                            |
-| false                   | 3.14                         |
-| false                   | true                         |
-| false                   | false                        |
-| false                   | {"id":11,"name":"Lakehouse"} |
-| false                   | [0,1]                        |
-| true                    | null                         |
-| true                    | null                         |
-+-------------------------+------------------------------+
-```
-
-* 如果parse_json的参数为非法json字符串，则返回SQL null，is null的结果为true
-* 如果输入字符串为`'null'`，则它会被解释为JSON null值，is null的结果为false
-
-### json_array/json_object
-
-类似array/named\_struct，可以根据已有的数据构造出对应的json类型
-
-```SQL
-SELECT json_array(), json_array(NULL),json_array(NULL::int, 1, TRUE, FALSE, NULL::int, "a", 1.2, 1.3d);
-+----------------+--------------------+--------------------------------------------------------------------------------------+
-| `json_array`() | `json_array`(NULL) | `json_array`(CAST(NULL AS int), 1, true, false, CAST(NULL AS int), 'a', 1.2BD, 1.3d) |
-+----------------+--------------------+--------------------------------------------------------------------------------------+
-| []             | [null]             | [null,1,true,false,null,"a","1.2",1.3]                                               |
-+----------------+--------------------+--------------------------------------------------------------------------------------+
-
-SELECT json_object(), json_object('k', NULL), json_object('k1', json_array(1, "a"), "k2", array(1, 2, 3));
--- !query output
-+-----------------+--------------------------+-------------------------------------------------------------------+
-| `json_object`() | `json_object`('k', NULL) | `json_object`('k1', `json_array`(1, 'a'), 'k2', `array`(1, 2, 3)) |
-+-----------------+--------------------------+-------------------------------------------------------------------+
-| {}              | {"k":null}               | {"k1":[1,"a"],"k2":[1,2,3]}                                       |
-+-----------------+--------------------------+-------------------------------------------------------------------+
-```
-
-## 类型转换
-
-在LakeHouse中，可以使用`::json`或`CAST`函数将其他类型转换为JSON类型。以下是一些类型转换的例子：
-| Json       | SQL           |
-| ---------- | ------------- |
-| Object     | Struct        |
-| Array      | Array         |
-| String     | string        |
-| Number     | bigint/double |
-| true/false | bool          |
-| Null       | 无对应类型         |
-| 无对应类型      | binary        |
-
-* 不存在于表格中的类型转换，会先将其转换为可以转换的类型（大多数情况为string类型），再转换为目标类型，例如cast(1.2 as json) 1.2为decimal类型，会先转换为string类型，进一步转换为json类型，结果是JSON '"1.2"'，而不是JSON '1.2'。
-* 需要注意的是cast(string as json)的语义和parse\_json(string)的语义并不一致,parse\_json 会尝试将 JSON 字符串解析成 JSON 对象，如果JSON格式不正确，则会生成 NULL而cast(string to json)**会将字符串整体当做JSON中的string类型,所以如果您是一个json格式字符串转化时应该使用parse_json**

-
-需要注意的是，`cast(string as json)`和`parse_json(string)`的语义并不一致。`parse_json`会尝试将JSON字符串解析成JSON对象，如果JSON格式不正确，则会生成NULL；而`cast(string to json)`会将字符串整体当做JSON中的string类型。

-
-# 使用SDK（igs/bulkload）写入JSON
-
-Lakehouse 支持给 JSON 类型的列写入 String 类型的字符串，系统在导入的时候会自动将字符串解析成 JSON 类型，如果用户输入了不符合 JSON 规范或者 CZ 不支持的 JSON 字符串，系统会报错并停止导入。
-
-# 导出JSON数据
-
-Lakehouse 支持以字符串的形式导出 JSON 数据。
-
-# 查询JSON数据
-
-查询JSON数据需要使用`json_extract`系列函数，通过JSON path获取需要的数据。以下是一些查询JSON数据的例子：
-
-* json\_extract
-* json\_extract\_boolean
-* json\_extract\_float
-* json\_extract\_double
-* json\_extract\_int
-* json\_extract\_bigint
-* json\_extract\_string
-* json\_extract\_date
-* json\_extract\_timestamp
-
-### json path规范
-
-json\_extract的第二个参数为json path，可以参考[json path规范](<https://goessner.net/articles/JsonPath/>)
-
-* "$"表示根元素
-* ".key"或者"\['key']" 用来查找json object中的key。特殊的，"\[\*]"表示获取所有的value,要求必须是单引号
-* "\[index]" 用来根据index访问 json array的元素，起始值为0。特殊的，"\[\*]"表示所有的元素
-
-```SQL
-SELECT json_extract(j, "$[0]"),
-       json_extract(j, "$[1]"),
-       json_extract(j, "$[*]")
-FROM VALUES (JSON '["a", 1, null]') as t(j);
-+-------------------------+-------------------------+-------------------------+
-| json_extract(j, '$[0]') | json_extract(j, '$[1]') | json_extract(j, '$[*]') |
-+-------------------------+-------------------------+-------------------------+
-| "a"                     | 1                       | ["a",1,null]            |
-+-------------------------+-------------------------+-------------------------+
-
-
-SELECT json_extract(j, "$.key"),
-       json_extract(j, "$['key.with.dot']"),

-# 性能对比
-
-构造的数据为1000多万条这样格式`{"address":"89695 Lind Common, Kellymouth, AK 61747","email":"``danita.weber@gmail.com``","name":"Golda Shields"}`，使用where进行过滤查询
-
-使用string查询，执行时间为20.4s。
-
-```SQL
-create table bulkload_data_string(data string);
-select get_json_object(data,'$.email') from bulkload_data_string where get_json_object(data,'$.email')='danita.weber@gmail.com'
-;
-```
-

-
-使用json存储数据执行时间为531ms,因为读取的时候进行列裁剪数据大小也会减少,如下图只需要读取153MB数据，string类型需要全量读取454MB数据
-
-```SQL
-create table bulkload_data(json string);
-select json_extract_string(data,'$.name') from bulkload_data where json_extract_string(data,'$.email')='danita.weber@gmail.com'

-## 功能概述
-
-> **【预览发布】** 本功能当前处于公开预览阶段。
-
-本文主要介绍如何在 SQL 中创建与 Kafka 消息队列系统连接的外部表。通过定义外部表，可以方便地从 Kafka 中读取数据流，并将这些数据作为表进行查询和分析。
-
-## 创建存储连接
-
-首先，需要创建一个存储连接，用于连接到 Kafka 服务器。目前不支持需要客户端证书的连接方式。
-
-### 语法
-
-```SQL
-CREATE STORAGE CONNECTION connection_name
-    TYPE kafka
-    BOOTSTRAP_SERVERS = ['server1:port1', 'server2:port2', ...]
-    SECURITY_PROTOCOL = 'PLAINTEXT';
-```
-
-### 参数说明
-
-* **connection_name**: 连接的名称，用于后续引用。
-* **TYPE**: 连接类型，此处为 `kafka`。
-* **BOOTSTRAP_SERVERS**: Kafka 集群的地址列表，格式为 `['host1:port1', 'host2:port2', ...]`。
-* **SECURITY_PROTOCOL**: 安全协议，可以是 `PLAINTEXT` 等。
-
-### 示例
-
-```SQL
-CREATE STORAGE CONNECTION test_kafka_conn
-    TYPE kafka
-    BOOTSTRAP_SERVERS = ['47.99.48.62:9092']
-    SECURITY_PROTOCOL = 'PLAINTEXT';

-# 云器 Lakehouse 基本概念
-
-欢迎使用云器 Lakehouse！本章节将为您详细介绍云器 Lakehouse 中的基本概念，帮助您更好地理解和使用本产品。
-
-## 账户（Account）
-
-云器的账户代表与云器公司建立商业关系的组织或个人（一般为企业账户），涵盖账户注册、服务开通等行为。账户是您使用云器产品服务、付费、获取服务支持的基本实体对象。注册时，系统会自动生成全局唯一的账户名，作为您在云器产品中的唯一标识。
-
-* 账户负责充值、出账单、费用支付以及订购/变更云器产品；
-* 所有企业或个人在云器产品上开通的服务实例及其资源对象都归属于特定账户。
-
-## 账户 URL
-
-每个账户都有一个唯一的账户 URL，用于访问管理中心。您需要使用该账户下的有效用户名和密码登录。账户 URL 的格式为：`<account_name>.accounts.clickzetta.com`。例如，以下链接中的 `0256c297` 即为账户名称：`0267c297.accounts.clickzetta.com`。
-
-## 用户（User）
-
-在账户注册成功后，您可以创建多个用户共同使用同一个账户内的资源。不同用户间可以通过权限控制分配可使用的数据和资源。
-
-## 服务实例（Lakehouse Instance）
-
-Lakehouse 服务实例是云器 Lakehouse 产品服务的载体。开通 Lakehouse 服务时，您需要根据指定的云服务商和地域，在您的账户下创建生成服务实例。一个账户下可以创建一个或多个服务实例（当前阶段默认开放单个服务实例的创建）。
-
-服务实例内采用统一元数据管理数据对象、计算资源、作业任务，并在统一权限体系下使用数据集成、开发调度、运维监控、数据目录等工具进行应用构建和数据管理。服务实例具备区域属性，其计算、数据和其他服务资源均在此云服务商的区域内。不同服务实例间默认相互隔离。
-
-![示意图](![](.topwrite/assets/Lakehouse服务实例.png =640))
-
-## 工作空间（Workspace）
-
-工作空间是用于组织 Lakehouse 资源对象（数据对象、计算资源、用户等），并提供配套的数据开发能力（数据集成、数据开发、数据运维）的逻辑对象。您可以在一个服务实例下创建多个工作空间。工作空间之间默认隔离，用户需加入工作空间，才可使用工作空间内的对象。通过跨工作空间授权的方式，实现同一实例下不同工作空间内对象的共享。如何管理和使用工作空间，可以参考[此文档](worksapce-manage.md)。
-
-## 计算资源（Virtual Cluster）
-
-计算资源由多实例虚拟计算集群和运行在集群中的计算服务构成，为您的作业提供计算环境，包括 CPU、内存以及临时存储。详见[此文档](virtual-cluster.md)。
-
-## 数据源（Data Source）
-
-数据源保存了数据存储的链接串信息，例如数据库的地址、访问用户名、密码等。数据源可用于配置数据同步任务或进行数据分析时引用、消费数据。详见[此文档](config-datasource.md)。
-
-## Schema
-
-在工作空间内，Schema 是一组数据库对象的命名空间，包括表、视图等。您可以在一个工作空间内包含多个命名各异的 Schema 对象。
-
-## 表（Table）
-
-表是格式化的二维数据表格。
-
-## 视图（View）
-
-视图是一种虚拟存在的表，不在数据库中实际存在。在使用时，视图会动态生成。
-
-## 物化视图（Materialized View）
-
-物化视图是一种特殊的视图，与普通视图不同，物化视图在数据库中实际存在，并占用存储资源。详见[此文档](materialized_ddl.md)。
-
-## Lakehouse Studio
-
-Lakehouse Studio 是一个以 Web 方式提供的集成开发和管理工具集合，也是 Lakehouse 原生提供的图形化操作界面，旨在为用户提供丰富的一站式功能和直观便捷的操作体验。通过浏览器登录并进入 Lakehouse Studio 后，可以在界面上轻松地操作和使用各项产品功能，比如上传/导入或同步数据、开发 SQL 任务、调度运行、配置监控告警、进行运维操作、管理用户和权限等。相较于通过 JDBC 协议连接或使用 CLI 命令行工具访问，Lakehouse Studio 可以提供更为丰富的原生功能，并且更加方便易用。详见[此文档](studio_manual.md)。
-
-## 任务开发
-
-任务开发是一站式的集成大数据开发环境。您可以在此进行任务开发、调试运行、配置调度以及提交发布等操作，完成整个大数据汇聚、加工、处理、分析的关键流程。在左侧导航菜单中，点击“开发”后可以进入 Web IDE 的主界面。详见[此文档](task_development.md)。
-
-## 任务组
-
-任务组是开发板块内用于管理一组任务的虚拟业务管理组。您可以使用任务组对一系列任务进行组织编排，包括添加/创建任务节点、创建任务节点之间的依赖关系，配置任务组参数、统一批量提交的操作。详见[此文档](task_group.md)。
-
-## 运维中心
-
-运维中心提供对任务和实例的运维管理操作。它集中管理手动触发执行的任务、周期调度的任务及其对应的实例。详见[此文档](task-instance-maintenance.md)。
-
-## 数据目录
-
-数据目录是连接数据提供者和数据消费者的桥梁。它基于表的元数据信息构建，并提供全局检索和过滤功能，便于快速查找表和查看详情，为数据消费提供协助。详见[此文档](data_catalog.md)。
-
-## 工作流（Workflow）
-
-工作流是由一个或多个通过依赖关系连接的任务组成的数据加工作业流。工作流指定了任务的运行环境和资源。作业可以按需执行、周期性执行或被事件触发执行。
-
-## 工作流实例（Workflow Instance）
-
-当工作流任务被触发执行时，会生成工作流实例。工作流实例包含实例化的时间戳和任务状态，由调度系统根据触发条件创建。
-
-## 任务（Task）
-
-任务是原子的数据开发任务，如数据同步任务、SQL 任务、Python 任务、SHELL 任务等。任务以文件方式创建、保存和组织管理。
-
-### Lakehouse SQL 任务
-
-指 Lakehouse 中通过 Web 端数据开发功能或 CLI、JDBC 连接等生成的 SQL 查询任务。如何开发和调度一个Lakehouse SQL任务，可以参考[此文档](taskdevelop.md)。
-
-### 同步任务
-
-指数据同步类型的任务。用户通过配置同步数据源和目标数据表生成同步任务。同步任务也消耗计算资源，并进行计量。同步任务包含离线同步任务和实时同步任务两大类。详见[此文档](data-integration.md)。
-
-### Python任务
-
-Python任务是指可以编写和运行Python代码的任务类型。对于许多数据分析和处理场景，特别是 BI+AI 分析场景，结合使用 Python 和 SQL，可以极大提高效率。 在云器 Lakehouse 里，通过提供 Python 脚本的任务类型，来运行 Python 代码。详见[此文档](Python_Task.md)。
-
-### JDBC任务
-
-JDBC 任务是数据开发中的一类重要任务节点，通过它可以编写 SQL 代码来连接支持 JDBC 协议的数据源，实现数据的增删改查等操作。详见[此文档](jdbc_task.md)。
-
-## 任务实例（Task Instance）
-
-数据开发任务在手动执行或定时调度执行时生成的具体执行实例。
-
-***
-
-通过 [此文档](object_model_design.md) 可以查看更多概念和对象模型设计。

-## LATERAL VIEW
-
-`LATERAL VIEW` 子句与生成器函数（如 EXPLODE、POSEXPLODE 等）结合使用，可以生成一个或多个包含行的虚拟表。该子句允许用户对输入的数组或映射进行操作，并将结果展开为独立的行。
-
-## 语法格式
-
-```
-SELECT ...
-FROM table_reference 
-LATERAL VIEW [OUTER] generator_function [ alias ] AS column_identifier [, ...]
-```
-
-## 参数说明
-
-* **OUTER**：可选参数。如果指定了 `OUTER` 关键字，当输入数组或映射为空或为 Null 时，将返回 Null 值。
-* **generator\_function**：生成器函数，如 EXPLODE、POSEXPLODE 等。
-* **alias**：可选参数。为 generator\_function 指定的别名。
-* **column\_identifier**：列出列别名，用于 `generator_function` 输出的行。列标识符的数量必须与生成器函数返回的列数相匹配。
-
-## 使用示例
-
-**准备数据**
-
-```
-CREATE TABLE employees(id int,name string,skills array<string>);
-INSERT INTO employees (id, name, skills) VALUES
-(1, 'John Doe', ['Java', 'Python', 'SQL']),
-(2, 'Jane Smith', ['C++', 'Hadoop', 'SQL']),
-(3, 'Bob Johnson', ['Python', 'Docker']);
-```
-
-**示例 1：使用 EXPLODE 函数**
-假设我们有一个名为 `employees` 的表，其中包含一个名为 `skills` 的数组类型的字段，我们想要将每个员工的技能拆分成单独的行。
-
-```
-SELECT e.id, e.name, s.skill
-FROM employees e
-LATERAL VIEW EXPLODE(e.skills) s AS skill;
-+----+-------------+--------+
-| id |    name     | skill  |
-+----+-------------+--------+
-| 1  | John Doe    | Java   |
-| 1  | John Doe    | Python |
-| 1  | John Doe    | SQL    |
-| 2  | Jane Smith  | C++    |
-| 2  | Jane Smith  | Hadoop |
-| 2  | Jane Smith  | SQL    |
-| 3  | Bob Johnson | Python |
-| 3  | Bob Johnson | Docker |
-+----+-------------+--------+
-```
-
-**示例 2：使用 POSEXPLODE 函数**
-`POSEXPLODE` 函数与 `EXPLODE` 类似，但它还会返回数组中元素的位置索引。使用相同的 `employees` 表和插入的数据，我们可以使用 `POSEXPLODE`：
-
-```
-SELECT e.id, e.name, ps.position, ps.skill
-FROM employees e
-LATERAL VIEW POSEXPLODE(e.skills) ps AS position, skill;
-+----+-------------+----------+--------+
-| id |    name     | position | skill  |
-+----+-------------+----------+--------+
-| 1  | John Doe    | 0        | Java   |
-| 1  | John Doe    | 1        | Python |
-| 1  | John Doe    | 2        | SQL    |
-| 2  | Jane Smith  | 0        | C++    |
-| 2  | Jane Smith  | 1        | Hadoop |
-| 2  | Jane Smith  | 2        | SQL    |
-| 3  | Bob Johnson | 0        | Python |
-| 3  | Bob Johnson | 1        | Docker |
-+----+-------------+----------+--------+
-
-```
-
-## 注意事项
-
-* 使用 `LATERAL VIEW` 子句时，请确保已正确指定生成器函数、别名和列标识符。

-### 步骤3：MCP Server 端：启动 MCP Server 镜像
-
-创建 `docker-compose.yml` 文件，拷贝内容到文件中（文件内容详见附录）
-
-在包含该文件的目录下打开终端或命令行，并执行以下命令。
-
-```SQL
-docker compose up -d
-```
-
-预期输出：
-
-```
-bash-3.2$ docker compose up -d
-[+] Running 4/4
- ✔ Network mcp_docker_clickzetta-net  Created       0.0s 
-   ✔ Container clickzetta-sse           Started       0.2s 
-   ✔ Container clickzetta-http          Started       0.2s 
-   ✔ Container clickzetta-webui         Started       0.2s
-```
-
-校验状态，使用 `docker compose ps --format "table {{.Name}}\t{{.Service}}\t{{.Status}}"` 命令，预期输出如下(忽略 `WARNING` 信息)：
-
-```
-bash-3.2$ docker compose ps --format "table {{.Name}}\t{{.Service}}\t{{.Status}}"
-
-NAME               SERVICE            STATUS
-clickzetta-http    clickzetta-http    Up 5 hours (unhealthy)
-clickzetta-sse     clickzetta-sse     Up 5 hours (unhealthy)
-clickzetta-webui   clickzetta-webui   Up 5 hours (unhealthy)
-```
-
-> 如果需要关闭，请在包含`docker-compose.yml`文件的目录下执行：`docker compose down`
-
-### 步骤4：配置 Claude Desktop
-
-本示例选择的 MCP 客户端工具是 Claude Desktop，主机与 MCP Server 端位于同一台主机
-
-找到并打开 Claude Desktop 配置文件：
-
-**macOS 操作步骤**：
-
-* 打开 Finder
-* 按 `Cmd+Shift+G`
-* 粘贴路径：`~/Library/Application Support/Claude`
-* 双击打开 `claude_desktop_config.json`（用文本编辑器）
-
-**Windows 操作步骤**：
-
-* 按 `Win+R` 打开运行对话框
-* 输入 `%APPDATA%\Claude` 并回车
-* 右键点击 `claude_desktop_config.json`
-* 选择"编辑"或"用记事本打开"
-
-2\. 将以下内容复制到配置文件（替换原有内容或添加到 `mcpServers` 中）：
-
-请输入 MCP Server 的地址：如果服务器与客户端运行在同一台机器上，请填写 `localhost`；否则，请填写服务器的 IP 地址。
-
-```JSON
-{
-  "mcpServers": {
-    "clickzetta-http": {
-      "command": "npx", 
-      "args": [
-        "-y", "mcp-remote",
-        "http://<YOUR_SERVER_IP>:8002/mcp",
-        "--allow-http",
-        "--transport", "http"
-      ]
-    }
-  }
-}
-```
-
-**配置完成**！
-
-^
-
-另外：Claude Desktop 支持通过多种方式连接后端的 MCP Server，以适应不同的部署环境和性能需求。上面的示例介绍了 **HTTP (Streamable**) 协议连接方式，如果想利用 **SSE** 或者 **STDIO** 协议连接，配置也很简单：
-
-**SSE 连接方式（远程服务**）
-
-SSE (Server-Sent Events) 是一种基于 HTTP 的长连接技术，允许服务器向客户端单向推送消息。相比于传统的轮询方式，SSE 能够以更低的延迟实现实时通信。
-
-* **适用场景**：需要从服务器实时接收数据流或更新通知的场景。
-* **Docker Server 配置参考**：此方式对应启动容器中的 `clickzetta-sse` 的服务，该服务在 `8003` 端口上提供服务。
-* **配置示例**：
-  在 Claude Desktop 的 `claude_desktop_config.json` 配置文件中更新如下信息，连接到远程 SSE 端点。
-
-```JSON
-
-{
-  "mcpServers": {
-    "clickzetta-remote-sse": {
-      "command": "npx",
-      "args": [
-        "-y", "mcp-remote",
-        "http://localhost:8003/sse",
-        "--allow-http",
-        "--transport", "sse"
-      ]
-    }
-  }
-}
-```
-
-&#x20;**说明**：
-
-* 请将 `<YOUR_SERVER_IP>` 替换为 MCP Server 实际的 IP 地址或域名。
-* 目标端口为 `8003`，端点路径为 `/sse`。
-* `--transport sse` 参数指明了使用 SSE 通信协议。
-
-***
-
-**STDIO 连接方式（本地进程**）
-
-此方式主要用于本地开发和调试。Claude Desktop 会将 MCP Server 作为一个子进程直接在本地启动，并通过标准输入/输出（STDIO）进行通信。这种方式延迟最低，但不适用于远程连接。
-
-* **适用场景**：本地开发、单机部署。
-* **Docker Server 配置参考**：此方式对应启动容器中的 `clickzetta-stdio` 的服务，该容器镜像会随着 Claude Desktop 的开启和关闭，自动操作容器镜像拉起和停止。
-* **配置示例**：在 Claude Desktop 的 `claude_desktop_config.json` 配置文件中更新如下信息，直接指定启动本地 Server 的命令。
-
-**注意**：
-
-1. 配置文件中 `-v `后的路径中 `USERNAME `**请根据系统的实际路径进行修改**。
-2. 请使用 `docker compose down `关闭创建的相关容器，因为此种方式下，Claude Desktop 会随着自身的开启和关闭，自动操作容器镜像拉起和停止。
-
-```json
-{
-  "mcpServers": {
-    "clickzetta-stdio": {
-      "command": "docker",
-      "args": [
-        "run", "-i", "--rm",
-        "--stop-timeout", "60",
-        "-p", "8502:8501",
-        "-v", "/Users/derekmeng/.clickzetta:/app/.clickzetta",
-        "czqiliang/mcp-clickzetta-server:latest"
-      ]
-    }
-  }
-}
-```
-
-**说明**：
-
-* `command` 和 `args` 直接定义了如何在本地启动 MCP Server。
-* 无需指定 IP 地址和端口。
-* `--transport stdio` 参数指明了使用 STDIO 通信协议。
-
-## 开始使用：
-
-### 部署验证
-
-1\. 打开 Claude Desktop ，在输入框中，发送以下指令：
-
-```Plain
-列出所有 Clickzetta Lakehouse 可用的 MCP工具
-```
-
- 如果连接成功，您将看到一个包含 50+ 个工具的列表（注意：随着版本更新，工具的具体数量可能会有变化）
-
-2\. **验证 WebUI 界面**
-
-* 在您的浏览器中访问以下地址： `http://localhost:8503, `预期可以展示以下页面：
-
-:-: ![](.topwrite/assets/mcp_web_ui.jpeg =753)
-
-^
-
-如果以上两个步骤都顺利完成，恭喜您，您的应用已成功安装！
-
-### 第二步：配置您的第一个数据源 (Lakehouse)
-
-接下来，让我们配置一个 Lakehouse 连接，以便 Claude 可以访问您的数据。
-
-1. **打开连接管理器**
-
-   访问 WebUI 界面 `http://localhost:8503`，然后在左侧菜单中选择「**连接管理**」。
-
-2. **添加并填写连接信息**
-
-   点击「**添加新连接**」按钮，并根据提示准确填写您的 Lakehouse 连接信息（如主机、端口、凭证等）
-
-:-: ![](.topwrite/assets/mcp_webui_2.jpeg =765)
-
-***
-
-**测试并保存**
-
-1. 填写完毕后，点击「**测试连接**」按钮，确保所有配置信息无误且网络通畅。
-2. 测试通过后，点击「**保存**」完成配置。
-
-### 第三步：开始您的第一个查询
-
-现在一切准备就绪！您可以开始与您的数据进行交互了。尝试在 **Claude Desktop** 中提问：
-
-> "帮我看下有哪些 Lakehouse 实例"
-
-### 高级配置：配置云器产品文档知识库
-
-这个步骤会将云器 Lakehouse 产品知识库表集成进来，构建一个智能问答知识库。配置完成后，您将能够在 MCP Client（如 Claude Desktop）中，通过自然语言提问的方式，快速获得关于 Lakehouse 操作的官方指导和答案
-
-该功能的核心是利用**嵌入服务 (Embedding**) 和**向量搜索 (Vector Search**) 技术，将非结构化的文档转化为可供机器理解和检索的知识库。
-
-#### **第一步：配置嵌入服务**
-
-此步骤的目的是告诉 MCP 系统如何将用户的“问题”也转换成向量，以便在知识库中进行匹配。
-
-1. 在 MCP Server 管理界面，从左侧导航栏进入「**系统配置**」。
-
-2. 在主配置区，选择 「**嵌入服务**」 标签页。
-
-3. 找到并填写 **DashScope 配置**（默认）部分：
-
-   * **API Key**：粘贴您的阿里云百炼平台的 API 密钥。这是调用模型的身份凭证，请妥善保管。
-   * **向量维度 (Vector Dimension**)：输入您选择的嵌入模型所输出的向量维度。**此值必须与知识库文档向量化时使用的维度完全一致**。例如，截图中 `text-embedding-v4` 模型的维度是 `1024`。
-   * **嵌入模型 (Embedding Model**)：选择或填写用于将文本转换为向量的模型名称，例如 `text-embedding-v4`。
-   * **最大文本长度 (Max Text Length**)：设置模型一次可以处理的文本单元（Token）的最大数量。如果问题过长，超出部分将被忽略。![](.topwrite/assets/MCP_config_1.jpeg)
-
-4. 点击 **保存嵌入服务配置** 按钮。
-
-#### **第二步：配置向量搜索**
-
-此步骤的目的是告诉 MCP 系统去哪里、以及如何搜索已经存储好的文档知识库。
-
-1. 在 **系统配置** 页面，切换到 「**向量搜索**」 标签页。
-
-2. 填写 **向量表配置** 部分：
-
-   * **向量表名称 (Vector Table Name**)：准确填写存储了文档向量的完整表名。格式通常为 `数据库名.模式名.表名`，例如 `clickzetta_sample_data.clickzetta_doc.kb_dashscope_clickzetta_elements`。
-   * **嵌入列 (Embedding Column**)：填写该表中用于存储**文本向量**的列名，例如 `embeddings`。
-   * **内容列 (Content Column**)：填写该表中用于存储**原始文本内容**的列名，例如 `text`。当系统找到相关答案时，这里的内容会作为主要参考。
-   * **其他列 (Other Columns**)：可选。填写您希望一并检索出的元数据列，如 `file_directory`, `filename`，这有助于用户追溯信息的原始出处。
-
-3. 配置 **搜索参数**：保持默认即可，如果想进行修改，请参考下面的说明
-
-   * **距离阈值 (Distance Threshold**)：设置一个相似度匹配的严格程度。系统会计算问题向量与文档向量之间的“距离”，只有距离小于此值的文档才会被视为相关。**值越小，代表匹配要求越严格**。通常建议从 `0.80` 开始尝试。
-   * **返回结果数 (Number of Results to Return**)：定义单次查询从数据库中检索出的最相关文档的数量。例如，设置为 `5` 表示每次找出 5 个最相关的文档片段。
-   * **启用重排序 (Enable Reranking**)：勾选此项后，系统会对初步检索出的结果进行二次智能排序，以提高最准确答案出现在最前面的概率。![](.topwrite/assets/MCP_Vector_2.jpeg)

--- 查看数据概览
-SELECT doc_id, title, category, author_id, view_count 
-FROM ai_knowledge_base 
-ORDER BY doc_id;
-```
-
-### 2.2 基础查询模式
-
-**模式1：精确ID查找（布隆过滤器）**
-
-```sql
-SELECT doc_id, title, author_id, view_count
-FROM ai_knowledge_base
-WHERE author_id = 2001
-ORDER BY view_count DESC;
-
--- 预期结果：
--- doc_id: 1004, title: "智能搜索引擎优化策略", view_count: 1680
--- doc_id: 1001, title: "云器向量数据库技术深度解析", view_count: 1250
-```
-
-**模式2：分类精确匹配（keyword倒排索引）**
-
-```sql
-SELECT doc_id, title, category, view_count
-FROM ai_knowledge_base 
-WHERE category = '技术文档'
-ORDER BY view_count DESC;
-
--- 预期结果：返回3条技术文档记录
-```
-
-**模式3：内容搜索（chinese倒排索引）**
-
-```sql
-SELECT doc_id, title, view_count
-FROM ai_knowledge_base
-WHERE content LIKE '%平台%'
-ORDER BY view_count DESC;
-
--- 预期结果：返回包含"平台"的相关文档
-```
-
-**模式4：语义搜索（向量索引）**
-
-```sql
--- AI语义相似度搜索
-WITH query_vector AS (
-  SELECT ARRAY[0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1] || ARRAY_REPEAT(0.1, 760)::ARRAY<FLOAT> as qv
-)
-SELECT 
-    a.doc_id, 
-    a.title, 
-    COSINE_DISTANCE(a.embedding, q.qv) as similarity_score
-FROM ai_knowledge_base a, query_vector q
-WHERE a.embedding IS NOT NULL
-ORDER BY similarity_score ASC
-LIMIT 3;
-
--- 预期结果：按语义相似度排序，AI相关文档排名最前
-```
-
-***
-
-## 3. 索引选择决策框架
-
-### 3.1 决策树
-
-```
-查询需求分析
-├── 需要精确ID查找？
-│   └── YES → 布隆过滤器索引
-│       ├── 单表查询 → 单布隆过滤器
-│       └── 关联查询 → 多布隆过滤器
-├── 需要文本内容搜索？
-│   ├── 精确分类匹配 → keyword分词 + 倒排索引
-│   ├── 中文内容搜索 → chinese分词 + 倒排索引
-│   ├── 多语言处理 → unicode分词 + 倒排索引
-│   └── 复合文本查询 → 多倒排索引组合
-├── 需要语义相似搜索？
-│   └── YES → 向量索引 + 其他索引过滤
-└── 复杂业务查询？
-    └── 多索引融合策略
-```
-
-### 3.2 分词器选择指南
-
-**实际分词效果对比**：
-
-```sql
--- 验证不同分词器效果
-SELECT 
-    'chinese' as analyzer,
-    TOKENIZE('云器Lakehouse数据湖仓平台', map('analyzer', 'chinese')) as tokens
-UNION ALL
-SELECT 
-    'unicode' as analyzer,
-    TOKENIZE('云器Lakehouse数据湖仓平台', map('analyzer', 'unicode')) as tokens  
-UNION ALL
-SELECT 
-    'keyword' as analyzer,
-    TOKENIZE('云器Lakehouse数据湖仓平台', map('analyzer', 'keyword')) as tokens;
-```
-
-**实际分词结果**：
-
-| 分词器       | 分词结果                                            | 最佳应用场景   |
-| --------- | ----------------------------------------------- | -------- |
-| `chinese` | `["云器", "lakehouse", "数据", "湖仓", "平台"]`         | 中文内容智能搜索 |
-| `unicode` | `["云", "器", "lakehouse", "数据", "湖", "仓", "平台"]` | 多语言标题搜索  |
-| `keyword` | `["云器Lakehouse数据湖仓平台"]`                         | 分类标签精确匹配 |
-
-**选择原则**：
-
-* **category、status字段** → keyword（精确匹配，零开销）
-* **中文content、description** → chinese（智能分词，语义理解）
-* **混合语言title、name** → unicode（通用支持，细粒度搜索）
-

-
-## 4. 高级查询模式与优化
-
-### 4.1 多索引融合查询
-
-**场景：AI智能检索系统**
-

-
-## 6. 常见问题与故障排除
-
-### 6.1 索引创建问题
-
-**问题1：向量索引创建失败**
-
-```
-错误信息：向量维度不匹配
-解决方案：检查VECTOR(FLOAT, n)定义与实际数据维度是否一致
-```
-
-**问题2：布隆过滤器不生效**
-
-```
-原因：布隆过滤器仅对新数据生效，不支持BUILD INDEX
-解决方案：对于存量数据，考虑使用倒排索引替代
-```
-
-**问题3：中文分词效果不佳**
-
-```
-原因：使用了错误的分词器
-解决方案：中文内容使用'analyzer'='chinese'，精确匹配使用'keyword'
-
--- 验证分词效果
-SELECT TOKENIZE('测试文本', map('analyzer', 'chinese')) as chinese_tokens,
-       TOKENIZE('测试文本', map('analyzer', 'keyword')) as keyword_tokens;
-```
-
-**问题4：向量函数不可用**
-
-```
-错误信息：COSINE_DISTANCE函数未找到
-解决方案：确认版本支持，验证函数可用性
-
--- 验证向量函数
-SELECT COSINE_DISTANCE(
-    ARRAY[0.1, 0.2, 0.3]::ARRAY<FLOAT>
-
-### 5.2 查询优化问题
-
-**诊断流程**：
-
-1. 使用EXPLAIN分析查询计划
-2. 检查索引是否被正确使用
-3. 分析数据分布和倾斜情况
-4. 评估索引选择性
-
-**优化策略**：
-
-```sql
--- 避免的反模式
-WHERE UPPER(category) = 'TECH'           -- 函数调用破坏索引
-WHERE CAST(id AS STRING) = '123'         -- 类型转换影响性能
-WHERE content LIKE '%keyword%keyword%'   -- 复杂模式匹配
-
--- 推荐的写法
-WHERE category = 'tech'                  -- 直接匹配，预处理数据统一格式
-WHERE id = 123                          -- 类型匹配
-WHERE content LIKE '%keyword%'          -- 简单模式
-```
-
-### 5.3 故障排除检查清单
-
-**索引健康检查**：
-
-* [ ] 所有高频查询字段都有对应索引

-
-* 请注意，目前限制每个账户只能创建一个Lakehouse服务实例。
-
-## 实例初始化
-
-创建Lakehouse服务实例后，您可以在管理中心的“我的订阅”中找到并进入该服务实例。系统将自动进行初始化，包括：
-
-1. 创建第一个名为“quick\_start”的工作空间。
-2. 创建“quick\_start”工作空间内的第一个虚拟计算集群（Virtual Cluster），默认处于停止状态。
-3. 创建系统服务用户`sysservice_clickzetta`和`sysservice_auto_mv`。
-4. 将创建Lakehouse服务实例的用户设置为服务实例的管理员角色以及工作空间“quick\_start”的空间管理员（workspace\_admin）角色。此时，您将具备Lakehouse服务实例及“quick_start”工作空间的所有操作权限。后续，您可以通过用户和权限管理功能添加更多用户并分配相应权限。
-

-# 部署
-
-```JSON
-# 卸载插件
-./bin/logstash-plugin uninstall logstash-output-clickzetta && rm -rf ./vendor/local_gems/
-
-# 安装插件
-./bin/logstash-plugin install --no-verify --local logstash-output-clickzetta-0.0.1.gem 
-
-# 查看插件
-./bin/logstash-plugin list --verbose
-```
-
-> 安装插件时，虽然指定了 `--no-verify --local`，但仍似乎会去远程服务器上下载或校验某些包。所以安装时如果碰到长时间卡在 `installing ...` 环节，可以直接按 `Ctrl+C` 强制终止。此时插件可能已经安装成功，可以通过查看插件列表来验证。

-# MATERIALIZED VIEW（物化视图）
-
-物化视图是一种特殊的数据库对象，它可以定期缓存查询结果以提高性能和效率。由于物化视图中的数据是预先计算好的，因此查询物化视图通常比直接查询基表更快。当查询频繁运行或足够复杂时，这种性能差异可能会非常明显。因此，物化视图可以加速昂贵的聚合、投影和选择操作，尤其是那些频繁运行在大型数据集上的操作。
-
-## 物化视图
-
-* 物化视图可以提高重复使用相同子查询结果的查询的性能，并支持查询改写。
-* 当物化视图的基础表发生插入、覆写、更新、删除等操作时，物化视图会自动失效，无法用于查询改写。
-
-## 何时创建物化视图
-
-物化视图特别适用于以下情况：
-
-* 查询结果包含与基础表相比少量的行和/或列。
-* 查询结果需要大量处理，包括半结构化数据分析、长时间计算的聚合等。
-* 物化视图的基础表不经常变化。
-
-## 云器Lakehouse物化视图特点
-
-* 物化视图可以提高重复使用相同子查询结果的查询的性能。
-* 物化视图支持定时刷新功能。通过SQL语法创建定时刷新任务，与在应用程序级别手动维护物化视图相比，这种方式更有效且更不容易出错。
-
-## 物化视图与普通视图的选择
-
-通常，当决定创建物化视图还是普通视图时，可以使用以下标准：
-
-* 如果视图的查询结果不经常变化、结果使用频繁且查询消耗大量资源，则创建物化视图。
-* 如果视图的结果经常变化、结果不经常使用或查询不消耗太多资源，则创建普通视图。
-
-## 物化视图与表、普通视图和缓存结果的比较
-
-物化视图与表在某些方面相似，与普通（非物化）视图在其他方面相似。此外，物化视图与缓存结果有一些相似之处，特别是两者都允许存储查询结果以供将来重用。
-
-
-## 物化视图管理
-
-云器Lakehouse提供了以下DDL命令来创建和维护物化视图：
-* [创建物化视图](CREATEMATERIALIZEDVIEW.md)：创建物化视图需要指定基表、查询语句以及其他相关参数。创建成功后，物化视图将存储在数据库中，以便后续查询使用。
-* [删除物化视图](DROPMATERIALIZEDVIEW.md)：当物化视图不再需要时，可以通过执行删除操作来释放相关资源。
-* [刷新物化视图](REFRESH.md)：当物化视图中的数据需要更新时，可以通过执行刷新操作来更新物化视图的数据。
-
-更多操作请参考[物化视图命令详情](<materialized_ddl.md>)。
-
-## 应用场景
-
-以下使用场景重点介绍了物化视图的价值。如果您的应用场景符合以下条件，那么物化视图可以提高查询性能：
-
-* **预汇总数据**：如果您需要对大量数据进行汇总分析，物化视图可以利用定时任务进行预先汇总，从而提高查询性能。
-* **预过滤数据**：如果您的查询只需要读取表的特定部分，物化视图可以预先过滤数据，从而减少查询时的数据量。
-* **预联接数据**：如果您的查询需要联接多个表，尤其是大型表和小型表之间的联接，物化视图可以预先进行联接操作，从而提高查询性能。
-
-## Materialized View和Dynamic Table区别
-
-从Lakehouse的实现机制上来看，动态表是基于传统的物化视图演进而来，虽然两者有一些共性，但在定位上存在很大区别。
-
-**物化视图：性能优化利器** 物化视图是一种预计算并存储查询结果的特殊视图，它能够显著提升查询效率。与传统视图不同，物化视图将计算结果保存在类似表的结构中，使得后续相似查询能够被优化器自动识别并直接使用预存结果，从而减少重复计算，加快查询速度。
-
-**动态表：数据加工的高效工具** 动态表专注于数据加工，虽然也能提升查询性能，但它并不依赖于查询优化器的自动重写。物化视图只有保持数据是最新的才能用于查询改写；而动态表面向加工场景，其数据可能并不是最新的。
-
-**传统物化视图在某些产品中具有以下限制，目前Lakehouse没有这些限制**：
-
-1. 只能使用单个基表。物化视图不能基于复杂查询（即具有联接或嵌套视图的查询）。
-
-2. 物化视图不一定是增量刷新，每个系统的实现不同。少量系统为了节省计算资源、加快加工速度，在部分算子中实现了增量计算。
-
-**动态表的先进特性**：
-
-1. **增量识别与优化**：支持大数据环境下的文件粒度增量识别，实现实时增量读取和计算优化，以及写入优化。
-2. **智能决策**：通过基于成本的优化器(Cost-Based Optimizer)智能选择全量、增量或部分增量计算，以适应不同查询需求。
-3. **实时任务运维**：提供数据版本管理、回退和重跑等机制，为实时任务的运维提供全面支持。
-
-**数据时效性考量**：
-
-* 物化视图要求数据的即时更新，以确保查询改写的准确性。在基表数据变更时，Lakehouse采用定时刷新机制，确保物化视图的数据始终保持最新。
-* 动态表则更注重数据加工的灵活性，根据业务定义来调整数据的滞后性，而不强制要求数据必须实时更新。
-
-## 查询改写功能
-
-目前Lakehouse的查询改写功能处于Preview阶段。如果您需要使用该功能，在提交SQL查询时请使用以下配置：
-`set cz.optimizer.enable.mv.rewrite=true;`
-
-具体案例
-
-```SQL
-
-create table product_sales(sale_id int, product_name string, sale_date string, quantity_sold int);
-INSERT INTO product_sales (sale_id, product_name, sale_date, quantity_sold)
-VALUES
-(1, 'Widget', '2024-05-01', 10),
-(2, 'Widget', '2024-05-02', 20),
-(3, 'Gadget', '2024-05-01', 15),
-(4, 'Widget', '2024-05-03', 5);
-CREATE MATERIALIZED VIEW product_sales_filter AS
-SELECT    sale_id,
-          product_name,
-          sale_date
-FROM      product_sales
-WHERE     sale_id < 3;
-
-set cz.optimizer.enable.mv.rewrite=true;
-SELECT    sale_id,
-          product_name,
-          sale_date
-FROM      product_sales
-WHERE     sale_id < 2;
-
-set cz.optimizer.enable.mv.rewrite=true;
-SELECT    sale_id,
-          product_name
-FROM      product_sales
-WHERE     sale_id < 2;

-### Q\&A
-
-#### 1. Claude Desktop 提示找不到 npx / Failed to spawn process
-
-Q1：Claude Desktop 配好 MCP Server 后连不上，日志里出现 `Failed to spawn process: No such file or directory`
-
-**A**：这通常表示 Claude Desktop 在启动本地 MCP 连接时，需要执行你配置里的 `command`（常见是 `npx`），但在 Claude Desktop 的运行环境里找不到该可执行文件（或无法在 PATH 中定位）。
-在本文的 HTTP(streamable) 示例中，`command` 默认是 `npx`，而 `mcp-remote` 依赖 Node.js/npm 环境。
-
-**修复方式为**：
-
-**在macOS系统中**：
-
-**1）确认本机是否安装了 Node.js（含 npx**）
-打开 Terminal 执行：
-
-* `node -v`
-* `npx -v`
-* `which npx`
-
-若 `npx -v` 报错或 `which npx` 无输出，说明 Node.js/npm 未安装或不可用。
-
-**2）安装 Node.js（推荐让 GUI 应用也能找到 npx**）
-
-* \*\*推荐方式：\*\*使用 Homebrew 安装 Node.js（npx 路径更稳定、GUI 应用更容易识别）。
-
-  * 若提示 `brew: command not found`，先安装 Homebrew，再 `brew install node`。
-
-* \*\*替代方式：\*\*使用 Node.js 官方 macOS Installer 安装（同样可用）。
-
-**3）处理 GUI App 的 PATH 和 Terminal 不一致**
-即使 Terminal 里 `npx` 正常，Claude Desktop 仍可能找不到。此时建议：
-
-* 在 `claude_desktop_config.json` 里把 `"command": "npx"` 改为 **npx 的绝对路径**（以 `which npx` 输出为准），例如：
-
-  * Apple Silicon 常见：`/opt/homebrew/bin/npx`
-  * Intel 常见：`/usr/local/bin/npx`
-
-**4）重启 Claude Desktop 再验证**
-
-****
-
-**在windows系统中**：
-
-**1）确认 Node.js 是否安装并已加入 PATH**
-打开 PowerShell 或 CMD，执行：
-
-* `node -v`
-* `npx -v`
-* `where npx`
-
-若找不到，安装 Node.js（建议 LTS），安装时勾选 **Add to PATH**（或安装后手动把 Node 安装目录加入系统 PATH）。
-
-**2）如果 Claude Desktop 仍找不到 npx：用绝对路径指定命令**
-在 `claude_desktop_config.json` 中把 `"command": "npx"` 改为 `npx.cmd` 的绝对路径（以 `where npx` 输出为准），例如常见路径类似：
-
-* `C:\Program Files\nodejs\npx.cmd`
-
-**3）重启 Claude Desktop 再验证**

-# 功能
-
-
-`MERGE INTO` 语句用于根据源表或子查询中的值更新目标表中的记录。当源表包含目标表中的新行（待插入）、修改行（待更新）和删除行（待删除）时，可以使用此功能来同步目标表的数据。
-
-
-# 语法
-
-
-```SQL
-MERGE INTO target_table 
-   USING source_table
-   ON merge_condition
-   { WHEN MATCHED [ AND matched_condition ] THEN matched_action |
-    WHEN  MATCHED [ AND matched_condition ] THEN matched_action |
-    --当WHEN MATCHED语句和WHEN NOT MATCHED 语句同时存在时，MERGE INTO语句中只能存在一个WHEN NOT MATCHED
-    WHEN NOT MATCHED [ AND not_matched_by_source_condition ] THEN not_matched_by_source_action } 
--- 参数解释
-matched_action ::=
-    UPDATE SET <column_name> = <expr> [ , <column_name2> = <expr2> ... ] 
-    | DELETE 
-not_matched_action ::=
-    INSERT [ ( <column_name> [ , ... ] ) ] VALUES ( <expr> [ , ... ] )
-```
-
-
-## 参数说明
-
-
-- `target_table`：指定目标表，可以使用别名。
-- `source_table`：指定要与目标表进行比较的表或子查询，可以使用别名。
-- `merge_condition`：定义如何将源表中的行与目标表中的行进行匹配，返回布尔类型的表达式。
-- `WHEN MATCHED [ AND matched_condition ]`：当源行根据 `merge_condition` 和可选的 `matched_condition` 与目标表行匹配时，执行 `WHEN MATCHED` 子句。
-  - 如果对于匹配 `merge_condition` 的源行和目标行对，没有任何 `WHEN MATCHED` 条件的计算结果为 true，则目标行保持不变。
-  - 如果存在多个 `WHEN MATCHED` 子句，则会按照它们的指定顺序对其进行求值。每个 `WHEN MATCHED` 子句都必须具有一个 `matched_condition`。
-- `WHEN NOT MATCHED [ AND not_matched_condition ]`：当源行根据 `merge_condition` 和可选的 `not_matched_condition` 与目标表中的任何行都不匹配时，执行 `WHEN NOT MATCHED` 子句。
-  - 只能存在一个`WHEN NOT MATCHED`语句
-- `matched_action`：
-  - `DELETE`：删除匹配的目标表行。
-  - `UPDATE`：更新匹配的目标表行。使用 `UPDATE SET column1 = source.column1 [, column2 = source.column2 ...]`。
-- `not_matched_action`：
-  - `INSERT`：使用源数据集中的相应列插入目标表，支持指定字段插入。对于未指定的目标列，则插入为 `NULL`。
-
-
-## 注意事项
-
-
-当执行 `MERGE INTO` 语句可能产生不确定结果时，系统会报错。产生这种情况的原因有：
-
-
-1. 如果 `ON` 子句使得源表中的多于 1 行与目标表中的行匹配，SQL 标准要求引发错误。
-2. 如果 `ON` 子句使得源表中的多于 1 行与目标表中的行匹配，同时在 `AND case_predicate` 条件过滤后仍有多条记录。
-3. 当WHEN MATCHED语句和WHEN NOT MATCHED 语句同时存在时，MERGE INTO语句中只能存在一个WHEN NOT MATCHED
-4. 当存在多个 WHEN MATCHED 子句时，UPDATE 语句必须在 DELETE 语句之前。
-
-
-
-
-确定性结果的情况：
-
-
-1. 如果 `ON` 子句使得源表中的 1 行与目标表中的行匹配。
-2. 如果 `ON` 子句使得源表中的多于 1 行与目标表中的行匹配，同时在 `AND case_predicate` 条件过滤后只有一条记录。
-
-
-
-
-## 详细使用示例
-
-
-### 案例1：当匹配条件满足时，删除目标表中的数据
-
-
-**场景**：删除在源表中存在的所有用户记录（标记删除）
-
-
-**建表语句**
-
-
-```sql
--- 目标表：存储用户信息
-CREATE TABLE users_target (
-  id INT,
-  name STRING,
-  value INT,
-  updated_at STRING,
-  marked_for_deletion BOOLEAN
-);
-
-
--- 源表：待同步的用户数据
-CREATE TABLE users_source (
-  id INT,
-  name STRING,
-  value INT,
-  updated_at STRING,
-  marked_for_deletion BOOLEAN
-);
-```
-
-
-**目标表插入的数据：**
-```sql
-INSERT INTO users_target VALUES 
-(1, 'Alice', 100, '2024-01-01', false),
-(2, 'Bob', 200, '2024-01-02', false),
-(3, 'Charlie', 300, '2024-01-03', false);
-```
-
-```
-+----+---------+-------+------------+---------------------+
-| id | name    | value | updated_at | marked_for_deletion |
-+----+---------+-------+------------+---------------------+
-| 1  | Alice   | 100   | 2024-01-01 | false               |
-+----+---------+-------+------------+---------------------+
-| 2  | Bob     | 200   | 2024-01-02 | false               |
-+----+---------+-------+------------+---------------------+
-| 3  | Charlie | 300   | 2024-01-03 | false               |
-+----+---------+-------+------------+---------------------+
-```
-
-
-**源表插入的数据：**
-```sql
-INSERT INTO users_source VALUES 
-(1, 'Alice', 100, '2024-01-01', false),
-(2, 'Bob', 200, '2024-01-02', false);
-```
-
-```
-+----+-------+-------+------------+---------------------+
-| id | name  | value | updated_at | marked_for_deletion |
-+----+-------+-------+------------+---------------------+
-| 1  | Alice | 100   | 2024-01-01 | false               |
-+----+-------+-------+------------+---------------------+
-| 2  | Bob   | 200   | 2024-01-02 | false               |
-+----+-------+-------+------------+---------------------+
-```
-
-
-**MERGE SQL**
-
-
-```sql
-MERGE INTO users_target t USING users_source s
-ON t.id = s.id
-WHEN MATCHED THEN DELETE;
-```
-
-
-**执行结果**
-
-
-```
-+----+---------+-------+------------+---------------------+
-| id | name    | value | updated_at | marked_for_deletion |
-+----+---------+-------+------------+---------------------+
-| 3  | Charlie | 300   | 2024-01-03 | false               |
-+----+---------+-------+------------+---------------------+
-```
-
-
-**说明**：源表中 id 为 1 和 2 的记录在目标表中找到匹配项，这两条记录被删除。id 为 3 的 Charlie 记录因为在源表中没有匹配项，保持不变。
-
-
-
-
-### 案例2：基于时间戳的条件更新
-
-
-**场景**：只在源表数据更新时间比目标表更新时间更新时，才更新目标表的值
-
-
-**建表语句**
-
-
-```sql
--- 目标表：产品信息
-CREATE TABLE products_target (
-  id INT,
-  name STRING,
-  col1 STRING,
-  updated_at STRING
-);
-
-
--- 源表：新的产品数据
-CREATE TABLE products_source (
-  id INT,
-  name STRING,
-  col1 STRING,
-  updated_at STRING
-);
-```
-
-
-**初始目标表数据：**
-```sql
-INSERT INTO products_target VALUES 
-(1, 'Product A', 'value_old', '2024-01-01'),
-(2, 'Product B', 'value_old', '2024-01-02'),
-(3, 'Product C', 'value_old', '2024-01-03');
-```
-
-```
-+----+------------+-----------+------------+
-| id | name       | col1      | updated_at |
-+----+------------+-----------+------------+
-| 1  | Product A  | value_old | 2024-01-01 |
-+----+------------+-----------+------------+
-| 2  | Product B  | value_old | 2024-01-02 |
-+----+------------+-----------+------------+
-| 3  | Product C  | value_old | 2024-01-03 |
-+----+------------+-----------+------------+
-```
-
-
-**初始源表数据：**
-```sql
-INSERT INTO products_source VALUES 
-(1, 'Product A', 'value_new', '2024-01-10'),
-(2, 'Product B', 'value_old', '2024-01-01'),
-(4, 'Product D', 'value_new', '2024-01-04');
-```
-
-```
-+----+------------+-----------+------------+
-| id | name       | col1      | updated_at |
-+----+------------+-----------+------------+
-| 1  | Product A  | value_new | 2024-01-10 |
-+----+------------+-----------+------------+
-| 2  | Product B  | value_old | 2024-01-01 |
-+----+------------+-----------+------------+
-| 4  | Product D  | value_new | 2024-01-04 |
-+----+------------+-----------+------------+
-```
-
-
-**MERGE SQL**
-
-
-```sql
-MERGE INTO products_target t USING products_source s
-ON t.id = s.id
-WHEN MATCHED AND t.updated_at < s.updated_at THEN UPDATE SET t.col1 = s.col1;
-```
-
-**执行结果**
-
-
-```
-+----+------------+-----------+------------+
-| id | name       | col1      | updated_at |
-+----+------------+-----------+------------+
-| 1  | Product A  | value_new | 2024-01-01 |
-+----+------------+-----------+------------+
-| 2  | Product B  | value_old | 2024-01-02 |
-+----+------------+-----------+------------+
-| 3  | Product C  | value_old | 2024-01-03 |
-+----+------------+-----------+------------+
-```
-
-
-**说明**：
-- **Product A (id=1)**：源表的更新时间 `2024-01-10` > 目标表的 `2024-01-01`，条件满足，col1 被更新为 `value_new`
-- **Product B (id=2)**：源表的更新时间 `2024-01-01` ≤ 目标表的 `2024-01-02`，条件不满足，保持不变
-- **Product C (id=3)**：源表中没有对应记录（id=3），不进行任何操作，保持不变
-- **Product D (id=4)**：源表新增，由于不存在 ON 条件的 WHEN NOT MATCHED 子句，不插入
-
-
-
-
-### 案例3：删除标记与条件更新的组合
-
-
-**场景**：对用户数据进行操作，标记为删除的用户直接删除，其他匹配的用户更新其状态信息
-
-
-**建表语句**
-
-
-```sql
--- 目标表：用户信息

-# 账户管理指南
-
-本指南将详细介绍如何管理您的云器 Lakehouse 账户，包括登录管理中心、管理账户信息和用户等操作。
-
-## 1. 基本概念
-
-### 账户名称
-
-在云器 Lakehouse 中，每个账户都有一个唯一的标识，用于在全球范围内区分不同的账户。账户名称由一个8位的随机字符串组成，在您完成注册后，系统会自动生成。账户名称也决定了您的登录地址和部分访问配置。
-
-账户名称是您在云器 Lakehouse 内的唯一识别名称，一经生成后不可变更。您可以通过注册完成后的提示或管理中心的首页找到您的账户名称。
-

-
-^
-
-:-: ![](.topwrite/assets/image_1739329908616.png =783)
-
-### 登录地址
-
-在云器产品中，每个账户拥有其独立的登录地址。登录地址的为<你的账户名称>.accounts.clickzetta.com。
-
-:-: ![](.topwrite/assets/image_1739329970639.png =799)
-
-### 服务实例名称
-
-云器 Lakehouse 是一个多云的大数据平台，支持在多个云厂商的不同 region 下创建服务实例。每个服务实例的开通都相当于在该region内生成一个唯一标识并在基础设施资源中划分出一片逻辑区域，用于为您提供Lakehouse的相关服务。服务实例名称（instance_name）即为服务实例的唯一标识，在您开通服务实例时自动生成，由一段8位的随机字符串组成。您可在服务实例的URL，或服务实例首页右侧找到您的服务实例名称。
-
-:-: ![](.topwrite/assets/image_1740540520113.png =807)
-
-### 账户注册手机
-
-账户注册手机是您在创建账户并添加第一个用户时填写的手机号码。初始账户手机号与您在账户下的第一个用户的手机号码相同。账户管理员可以在管理中心中更改注册手机号。请妥善保管您的注册手机号，因为在云器产品中，每个注册手机号只能对应一个账户，这是找回账户的唯一凭证。
-
-:-: ![](.topwrite/assets/image_1739330026163.png =806)
-
-^
-^
-
-## 2. 账户名称与标识
-
-### 为什么需要账户名称
-
-* **全局唯一性**：账户名称可帮助您在云器 Lakehouse 的全局服务网络中，唯一区分您的账户。
-* **安全控制**：在启用账户安全策略和第三方应用集成时，账户名称是必需的信息，用于访问或交互。
-
-### 账户名称的常用场景
-
-Lakehouse的账户名称主要用于以下场景：
-
-**1. 登录Lakehouse Web 界面**
-
-当您要登录 Lakehouse 的管理中心或Web界面时，需要在浏览器中输入正确的账户 URL（<您的账户名称>.accounts.clickzetta.com）。
-
-^
-
-### 为什么需要服务实例名称
-
-* **全局唯一性**：实例名称可帮助您在云器 Lakehouse 的全局服务网络中，唯一区分您的服务实例。服务名称包含了region信息，可以直接与region内Lakehouse服务进行交互，简化了交互时的访问链路。
-* **安全控制**：在启用网络安全策略和使用第三方客户端访问Lakehouse时，服务名称是必需的信息，用于访问或交互。
-* **资源链接**：在进行数据共享等功能时，需要明确指定目标或源账户的服务实例名称。
-
-### 服务实例名称的常用场景
-
-**1. Lakehouse CLI / 其他客户端 / 驱动**
-
-当使用 CLI、JDBC 驱动、Python/R/Java 等客户端或第三方工具（如 BI 工具）连接 Lakehouse 时，需要在连接配置中指定服务实例名称。
-
-**2. 第三方应用与服务集成**
-
-当外部应用（如数据分析平台、ETL 工具、云存储服务）与 Lakehouse 交互时，需提供服务实例名称来确定目标 Lakehouse 服务。
-
-**3. 数据共享操作**
-
-在 Lakehouse 的“数据共享”功能中，需要使用服务实例名称来定义操作范围。
-
-^
-
-## Lakehouse账户URL与登录
-
-### 登录地址格式
-
-在云器 Lakehouse 中，每个账户拥有其独立的登录地址（URL）。一般格式如下：
-
-[https://<您的账户名称>.accounts.clickzetta.com](https://<您的账户名称>.accounts.clickzetta.com)
-
-示例：
-
-如果您的账户名称为41nprq1k，则登录地址为：
-
-41nprq1k.accounts.clickzetta.com
-
-### 使用账户名称登录
-
-您可以直接在浏览器中输入 `https://<您的账户名称>.accounts.clickzetta.com`，进入登录页面。在登录页面中，您需要输入或选择正确的账户名称，以及用户名和密码。您的账户下可能存在一个或多个用户，您可以在上述页面中登录任一用户。您也可以通过输入用户的手机号码找回用户名或重置用户密码。当多个用户共用一个手机号码时，您可以通过该手机号码找回所有关联的用户名，以便选择所需登录的用户。
-
-### 登录流程与找回方式
-
-1\. 访问 `https://<账户标识>.accounts.clickzetta.com` 或统一入口 `https://accounts.clickzetta.com`。
-
-2\. 在登录页面，输入或选择正确的账户名称，并输入您的 **用户名**、**密码**。
-
-3\. 如果忘记用户名或密码，可以在完成账户名称输入后，通过用户的手机号找回。
-
-当多个用户共用一个手机号码时，可通过该号码找回关联的所有用户名，并选择所需的用户登录。
-
-4\. 如果忘记账户名称，可以在登录页面通过账户的注册手机号找回，一个手机号仅对应一个注册账户。
-
-^
-
-## 在SQL / 配置文件 / 第三方工具中使用账户标识
-
-为了在各种环境下准确指定目标 Lakehouse 账户，您需要根据具体场景选择合适的账户标识格式：
-
-### 在SQL语句中使用
-
-当您在 Lakehouse SQL 中需要引用其他账户（例如进行数据共享）时，使用：服务实例名称（instance_name）。
-
-例如：
-
-`--为数据共享指定分享实例`
-
-`ALTER SHARE share_demo ADD INSTANCE <instance_name>;`
-
-### 在配置文件或第三方工具中使用
-
-* **SQL客户端、驱动或库配置**
-
-在某些SQL客户端（如DBeaver）JDBC驱动或Python/Java库的配置文件中，需要配置链接参数，例如配置DBeaver驱动时：
-
-:-: ![](.topwrite/assets/image_1740549280083.png =361)
-
-JDBC 连接字符串内，需要使用服务实例名称（instance_name），如：
-
-`jdbc:clickzetta://<your_instance_name>.ap-southeast-1-alicloud.api.clickzetta.com/demo_workspace?username=demo_user&password=DemoPassword&schema=public&virtualCluster=DEFAULT`
-
-再例如配置Python SDK时，需要使用服务实例名称（instance\_name）：
-
-`from clickzetta import connect`
-
-`# 建立连接`
-
-`conn = connect(username='username',`
-
-`               password='password',`
-
-`               service='<region\_id>.api.clickzetta.com',`
-
-`               instance='your_instance_name',`
-
-`               workspace='quickstart_ws',`
-
-`               schema='public',`
-
-`               vcluster='default')`
-
-^
-^
-
-## 维护账户信息
-
-### 查看账户注册手机
-
-当您使用具备账户管理员角色的用户登录云器后，可以在管理中心对您的账户进行管理。在“账户主页”页面，您可以查看账户的基本信息以及账户的登录URL。您还可以点击注册手机号右侧的“修改”按钮，更改账户注册的手机号码。
-请注意，您可在“账户中心”页面分别看到“账户信息”中的注册手机——这意味着该账户绑定的手机号码，可通过该手机号找回账户名称；以及“用户信息”中的“注册手机”——这意味着当前登录用户的手机号码，仅与当前登录用户身份绑定，可用于当前用户登录时的 MFA 验证、找回用户名、找回密码等操作。请注意区分。
-
-![](.topwrite/assets/image_1740550879753.png)
-
-### 修改账户注册手机
-
-如果需要修改账户注册手机，需要具备账户管理员（account_admin）身份的用户登录。在进入“账户中心”后，点击“账户信息”栏“注册手机”旁的修改按钮，在验证完旧手机号码后，可以录入并修改为新的手机号。

-# 使用 Zettapark 管理 Lakehouse Volume 的文件
-
-## 1. 概述
-
-云器 Lakehouse 通过其抽象存储层（[Volume](datalake_volume.md)、[Schema](SCHEMA.md) 和 [表](Tables.md)）和 Python API，提供对数据湖文件和数据仓库表的统一管理。本指南展示了如何在数据湖中执行文件管理操作，包括上传（PUT）、下载（GET）和列出（LIST）文件。
-
-**关键概念**：
-
-* **Volume存储抽象**：所有数据湖存储都映射到Volume对象。
-  * [External Volume](external_volume.md)：由客户管理，支持与 AWS S3 和阿里云 OSS 等云存储的集成。
-  * [Internal Volume](internal_volume.md)：由云器管理，分为USER VOLUME 和 TABLE VOLUME。
-* [Zettapark](ZettaparkQuickStart.md) **Python API**：提供文件和表集成的统一接口。
-
-你可以从[GitHub 存储库获取源代码（Jupyter Notebook ipynb 文件）](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/Zettapark/Managing%20Files%20on%20Datalake%20Volume%20with%20Zettapark.ipynb)。
-
-## 2. 环境设置
-
-### 1. 安装依赖项
-
-```bash
-pip install clickzetta_zettapark_python -U -i https://pypi.tuna.tsinghua.edu.cn/simple
-```
-
-### 2. 导入库并创建会话
-
-```python
-from clickzetta.zettapark.session import Session
-import json
-
-# 从配置文件加载连接参数
-with open('config.json', 'r') as config_file:
-    config = json.load(config_file)
-
-# 创建会话
-session = Session.builder.configs(config).create()
-print("会话创建成功！")
-```
-
-## 3. 文件操作
-
-### 1. 清理USER VOLUME
-
-在开始之前，清理USER VOLUME以确保环境干净：
-
-```python
-session.sql("REMOVE USER VOLUME SUBDIRECTORY '/'").show()
-```
-
-### 2. 列出USER VOLUME中的文件
-
-确认用户卷为空：
-
-```python
-session.sql("LIST USER VOLUME").show(10)
-```
-
-### 3. 上传文件到USER VOLUME
-
-根据文件类型将本地文件上传到用户卷的不同目录：
-
-```python
-import os
-
-# 遍历本地目录并上传文件
-for filename in os.listdir("data/"):
-    if filename.endswith("csv.gz"):
-        file_path = os.path.join("data/", filename)
-        session.file.put(file_path, "volume:user://~/csvgz/")
-    elif filename.endswith(".csv"):
-        file_path = os.path.join("data/", filename)
-        session.file.put(file_path, "volume:user://~/csv/")
-    elif filename.endswith(".json"):
-        file_path = os.path.join("data/", filename)
-        session.file.put(file_path, "volume:user://~/json/")
-    elif filename.endswith(".png"):
-        file_path = os.path.join("data/", filename)
-        session.file.put(file_path, "volume:user://~/png/")
-    elif filename.endswith(".jpg"):
-        file_path = os.path.join("data/", filename)
-        session.file.put(file_path, "volume:user://~/jpg/")
-    elif filename.endswith(".pdf"):
-        file_path = os.path.join("data/", filename)
-        session.file.put(file_path, "volume:user://~/pdf/")
-```
-
-### 4. 验证上传结果
-
-确认文件已成功上传：
-
-```python
-session.sql("LIST USER VOLUME").show(100)
-```
-
-## 4. 查看和下载文件
-
-### 1. 下载图像文件
-
-从用户卷下载图像并显示：
-
-```python
-from PIL import Image
-
-# 将图像下载到本地目录
-source_path = "volume:user://~/png/unstructured_tables.png"
-dest_path = "tmp/png/"
-session.file.get(source_path, dest_path)
-
-# 打开并显示图像
-try:
-    img = Image.open(dest_path + "unstructured_tables.png")
-    img.show()  # 显示图像
-except FileNotFoundError:
-    print(f"错误：文件 {dest_path} 不存在。请检查路径。")
-except Exception as e:
-    print(f"无法打开图像：{str(e)}")
-```
-
-## 5. 关闭会话
-
-完成操作后，关闭会话以释放资源：
-
-```python
-session.close()
-print("会话已关闭。")
-```
-
-## 6. 总结
-
-通过本指南，你已学习如何：
-
-1. 使用 Python API 管理用户卷中的文件。
-2. 在数据湖中上传、下载和列出文件。
-3. 查看图像文件并验证操作结果。
-
-**下一步**：
-
-* 探索卷的使用，实现文件和表的无缝集成。
-* 尝试对文件和表运行联合查询，体验统一 Lakehouse 的优势。

-
-## Real-Time Insurance Data ETL Pipeline with Snowflake项目介绍
-
-### 项目概况
-
-如果你熟悉Snowflake的实际操作和应用，那么Github上的[Real-Time Insurance Data ETL Pipeline with Snowflake](https://github.com/ravishankar324/Real-Time-Insurance-claims-Data-ETL-Pipeline) 对你是再熟悉不过了。该项目涉及在Snowflake中创建实时 ETL（提取、转换、加载）数据管道，以处理来自 Kaggle 的保险数据并将其加载到 Snowflake 中。数据管道使用 Apache Airflow 进行管理，涉及几个步骤来清理、规范化和转换数据，然后将其加载到 Snowflake 进行进一步处理。AWS S3 用作数据湖，用于存储原始数据和转换后的数据。
-
-开发完该项目后，可以根据需求安排 Airflow DAG 运行，确保 ETL 流程以所需的频率执行。最终清理、规范化和转换后的数据将可在 Tableau 中进行实时可视化，从而获得最新的见解和报告。项目架构图如下:
-
-:-: ![](.topwrite/assets/image_1737353888502.png =814)
-
-### 使用的工具和服务
-
-* **Python**：用于脚本编写和数据处理。
-* **Pandas**：用于数据操作和分析。
-* **AWS S3**：作为存储原始数据和转换后数据的数据湖。
-* **Snowflake**：用于数据建模和存储。
-* **Apache Airflow**：用于协调 ETL 工作流程。
-* **EC2**：用于托管 Airflow 环境。
-* **Kaggle API**：用于从 Kaggle 提取数据。
-* **Tableau**：用于数据可视化。
-
-### ETL 工作流
-
-1. **数据提取**
-
-   * 创建 Airflow DAG 脚本，使用 Kaggle API 从 Kaggle 保险数据集中提取随机数量的行。
-
-   * 清理、规范化并将数据转换为四个表：
-
-     * `policy_data`
-     * `customers_data`
-     * `vehicles_data`
-     * `claims_data`
-
-2. **数据存储**
-
-   * 将转换后的数据存储在 S3 存储桶中，并针对每种类型的规范化数据 ( `policy_data`、`customers_data`、`vehicles_data`、`claims_data`) 组织到不同的文件夹中。
-
-3. **Snowflake中的数据处理**
-
-   * 创建 Snowflake SQL 工作表来定义数据库模式。
-   * 在 Snowflake 中为每种类型的规范化数据创建暂存表。
-   * 定义 Snowpipes 以自动将数据从 S3 存储桶提取到暂存表。
-   * 为每个暂存表创建流对象以捕获变化。
-   * 创建最终表以合并来自流对象的新数据，确保仅插入不同的或新的行。
-
-4. **使用 Snowflake 流和任务更改数据捕获**
-
-   * 在 Snowflake 中创建任务以自动捕获变更数据。
-   * 当流对象中有新数据可用时，将触发每个任务以将数据加载到最终表中。
-
-5. **Airflow DAG 任务**
-
-   * **任务 1**：检查 Kaggle API 是否可用。
-   * **任务 2**：将转换后的数据上传到 S3 存储桶。

-* **资源管理与任务队列管理**：分别运用不同的 Virtual Cluster 处理 ETL、BI 以及数据质量的作业，达成资源隔离与任务队列管理。
-
-## Spark数据工程最佳实践项目介绍
-
-### Spark数据工程最佳实践项目背景
-
-在缺乏充分指导的情形下构建数据管道，可能会令人感到无所适从，难以判定自身是否遵循了最佳实践。倘若您身为一名数据工程师，期望明晰自身技术技能在构建数据管道方面的发展状况，但对是否遵循了行业标准存疑，也不确定能否与大型科技公司的数据工程师相较，那么 GitHub 上的 [Spark数据工程最佳实践](https://github.com/josephmachado/data_engineering_best_practices/tree/main) 项目便是为您量身定制的。本文将对设计数据管道、洞悉行业标准、考量数据质量以及编写可维护且易于操作的代码的最佳实践予以回顾。完成此项目后，您将洞悉设计数据管道的关键组件及其需求，并且能够迅速熟悉任何新的代码库。
-
-### Spark数据工程最佳实践项目场景
-
-假设我们从上游来源提取客户和订单信息，并创建订单数量的每小时报告。
-
-:-: ![](.topwrite/assets/image_1737530842475.png =405)
-
-使用的组件和环境如下：
-
-* 数据存储：MinIO with Delta Table Format
-* 数据处理：Spark
-* 代码语言：PySpark + Spark SQL
-* 数据质量：Great Expectations
-* 工作流：Airflow
-* 运行环境：本地Docker（Spark、Airflow）
-
-### Spark数据工程最佳实践项目最佳实践
-
-#### 使用标准模式逐步转换数据
-
-遵循既定的数据处理流程有助于处理常见的潜在问题，并且您可参考大量的资料。大多数行业标准模式均遵循三层数仓架构，具体如下：
-
-1. **原始层**：按上游源端的原始状态存储数据。此层有时会涉及数据类型的更改和列名的标准化。
-2. **转换层**：依据所选的建模原则对原始层的数据进行转换，从而形成一组表。常见的建模原则包括维度建模（Kimball）、Data Vault 模型、实体关系数据模型等。
-3. **消费层**：将来自转换层的数据加以组合，形成直接与最终用户用例相对应的数据集。消费层通常涉及连接和聚合转换层表，以方便最终用户对历史性能进行分析。**业务特定的指标**通常在此层定义。我们应确保**一个指标仅在一个位置定义**。
-4. **接口层（可选）**：消费层中的数据通常会遵循数据仓库的命名/数据类型等。然而，呈现给最终用户的数据应具备易用性和易理解性。接口层通常是作为仓库表与其消费者之间接口的**视图**。
-
-:-: ![](.topwrite/assets/image_1737530923177.png =808)
-
-^
-
-上图中的青铜层（Bronze Layer）、白银层（Silver Layer）、黄金层（Gold Layer）和接口层（User Interface）分别与上述的原始层、转换层、消费层和接口层相对应。我们针对白银层采用了维度建模的方法。对于管道/转换函数/表而言，输入被称为“上游”，输出则被称为“下游”消费者。在规模较大的公司中，多个团队在不同的层级上开展工作。数据采集团队或许会将数据导入青铜层，而其他团队能够依据自身需求构建属于自己的白银层和黄金层的表。
-
-^
-
-#### 在将数据提供给消费者之前确保数据有效（又称为数据质量检查）
-
-在构建数据集时，明确对数据的期望至关重要。对数据集的期望可以简单到列值符合要求，也可以复杂到满足更复杂的业务需求。若下游消费者使用了不良数据，其后果可能是灾难性的。例如，向客户发送错误的数据或基于不正确的数据进行资金支出。纠正不良数据使用的过程通常需要耗费大量时间，并重新运行所有受影响的流程！
-
-为防止消费者意外使用不良数据，我们应当在提供数据以供使用之前对其进行检查。
-
-本项目使用[Great Expectations](https://www.startdataengineering.com/post/ensuring-data-quality-with-great-expectations/) 库来定义和运行数据检查。
-
-#### 使用幂等的数据管道避免数据重复
-
-重跑，即重新运行数据管道，是一种常见操作。在重新运行数据管道时，我们必须确保输出不包含重复的行。系统在给定相同输入的情况下始终产生相同输出的特性称为幂等性。
-
-以下展示了重新运行数据管道时避免数据重复的两种技术：
-
-1. **基于运行 ID 的覆盖**：用于仅附加输出数据。请确保您的输出数据具有运行 ID 作为分区列（例如，我们的黄金表中的分区列）。运行 ID 表示创建的数据所属的时间范围。当重新处理数据时，依据给定的运行 ID 进行覆盖。
-2. **基于自然键的 UPSERTS**：在管道使用自然键对输出数据执行插入和更新时使用。当需要更新现有行的维度数据时（例如 SCD2 采用此方法）。重新运行管道产生的重复会致使现有行的更新（而非在输出中创建新行）。我们使用此方法来填充 dim\_customer 表。

-
-CREATE VCLUSTER IF NOT EXISTS data_engineering_best_practices_vc_bi
-   VCLUSTER_SIZE = XSMALL
-   VCLUSTER_TYPE = ANALYTICS
-   AUTO_SUSPEND_IN_SECOND = 300
-   AUTO_RESUME = TRUE
-   COMMENT  'data_engineering_best_practices_vc_bi';
-
-CREATE VCLUSTER IF NOT EXISTS data_engineering_best_practices_vc_dqc
-   VCLUSTER_SIZE = XSMALL
-   VCLUSTER_TYPE = GENERAL
-   AUTO_SUSPEND_IN_SECOND = 10
-   AUTO_RESUME = TRUE
-   COMMENT  'data_engineering_best_practices_vc_dqc';
-```
-
-### 任务参数配置

-
-如何获得参数值请参考 [这篇文章](https://uat-doc.clickzetta.com/JDBC-Driver)。
-
-^
-
-#### 02\_Pipeline ETL任务参数配置
-
-给如下任务配置参数，参数配置的方法同上。
-
-* sales\_mart.py
-
-### 创建环境
-
-运行 setup_env 和 DDL 临时任务，创建运行所需要的虚拟计算集群、数据库 Schema 以及 Tables。
-创建运行所需要的虚拟计算集群、数据库Schema：

-:-: ![](.topwrite/assets/image_1737534798871.png =599)
-
-创建Tables:
-
-:-: ![](.topwrite/assets/image_1737534852030.png =594)
-
-### 配置数据质量监控规则
-
-导航到[Lakehouse Studio](studio_overview.md)的数据->数据质量->质量规则，新建如下规则：
-
-:-: ![](.topwrite/assets/image_1737534933748.png =597)
-
-以expectation\_suite\_name是customer为例
-
-:-: ![](.topwrite/assets/image_1737535012940.png =594)
-
-配置如下规则：
-
-:-: ![](.topwrite/assets/image_1737535163110.png =615)
-
-### 工作流调度
-
-导航到[Lakehouse Studio](studio_overview.md)的开发->任务，
-对sales\_mart.py ETL任务进行调度配置：
-
-:-: ![](.topwrite/assets/image_1737535319989.png =578)
-
-从而实现1小时为周期的报表数据刷新。
-
-然后点击“提交”，按周期执行该ETL任务：
-
-![](.topwrite/assets/image_1737535401895.png =723)
-
-### 任务运维
-
-#### ETL任务运维
-
-导航到[Lakehouse Studio](studio_overview.md)的运维监控->任务运维，查看任务状态，执行日志、实例管理等。
-
-:-: ![](.topwrite/assets/image_1737535489873.png =712)
-
-#### 数据质量控制
-
-导航到[Lakehouse Studio](studio_overview.md)的数据->数据质量，在数据质量中可以配置质量规则来监控数据表的产出是否正常。
-
-查看校验对象：
-
-:-: ![](.topwrite/assets/image_1737535653201.png =729)
-
-查看校验结果：
-
-:-: ![](.topwrite/assets/image_1737535687027.png =720)
-
-^
-^
-
-#### 监控告警配置
-
-下一步可以导航到运维监控->监控告警，增加告警规则，实现对ETL任务和数据质量控制的实时告警。
-
-^
-
-**使用内置的监控告警规则**：
-
-在系统内部，内置了如下通用的监控告警规则，在数据质量校验失败时，会按照规则中的具体配置来触发邮件、短信、电话等告警。
-
-:-: ![](.topwrite/assets/image_1737600310887.png =720)
-
-^
-
-**使用自定义监控告警规则**：
-
-上述内置的监控告警规则，是对全局所有的质量监控规则的校验结果都生效。如果想进一步精细化控制告警的监测范围和告警策略，也可以自定义的新建规则，如下图所示，选择“质量规则校验失败”的监控事项，并给定限制范围的过滤条件。监控告警配置的详细指南，可以参考 [监控告警](monitoring_and_alerting.md) 使用指南。

-# N8N中集成Lakehouse MCP Server
-
-N8N 的 Agent 节点支持直接集成来自外部 [MCP](https://modelcontextprotocol.io/introduction) 服务器的[工具](https://modelcontextprotocol.io/docs/concepts/tools)。这为 Lakehouse 与您的 N8N AI 工作流集成提供了新方式。
-Lakehouse MCP Server 通过这种方式实现与 N8N 的集成，来自 Lakehouse MCP Server 的丰富工具可以在 N8N 的 Agent 节点中轻松调用。
-
-首先，您需要部署支持 [SSE协议的Lakehouse MCP Server](LakehouseMCPServer_intro.md)。
-
-## 在 N8N 工作流 AI Agent 节点中增加 MCP Client
-
-N8N MCP 客户端工具节点是一个[模型上下文协议 (MCP)](https://modelcontextprotocol.io/introduction)客户端，允许您使用外部 MCP 服务器公开的工具。您可以将 MCP 客户端工具节点连接到您的模型，以便使用 N8N 代理调用外部工具。**目前 N8N 仅支持 SSE 协议，还不支持通过 HTTP 协议与 MCP Server 互通**。
-
-:-: ![](.topwrite/assets/image_1756887369109.png =795)
-
-在 Agent 节点的 System Message 中填写：
-您是 ClickZetta Lakehouse 资深产品专家，擅长借助 MCP Server Tools 帮助用户回答和解决问题，避免编造。对于 ClickZetta Lakehouse 相关的问题，如果没有合适的 MCP Tool，您需要先通过 `get_product_knowledge` 这个 MCP Tool 查询产品知识库获得知识，然后再通过合适的 Tool 执行获得结果。
-
-## 配置AI Agent节点的MCP
-
-使用以下参数配置节点。
-
-* **SSE 端点**：您要连接的 MCP 服务器的 SSE 端点。
-
-* **身份验证**：用于向 MCP 服务器进行身份验证的身份验证方法。选择 **“无”** 则无需身份验证即可尝试连接。
-
-* **要包含的工具**：选择要向 AI 代理公开的工具：
-
-  * **全部**：公开 MCP 服务器提供的所有工具。
-  * **已选择**：激活 **要包含的工具** 参数，您可以在其中选择要向 AI 代理公开的工具。
-  * **除以下所有**：激活 **要排除的工具** 参数，您可以在其中选择要避免与 AI 代理共享的工具。AI 代理将可以访问所有未选中的 MCP 服务器工具。

-***
-
-## 核心差异和优势理解
-
-### 🚀 **Lakehouse分区的5大创新特性**
-
-#### 1. **智能转换分区函数**
-
-**创新价值**：避免与标准SQL函数冲突，提供更精确的时间分区控制
-
-```sql
--- ✅ Lakehouse的优雅设计
-CREATE TABLE events PARTITIONED BY (days(event_date));  -- 精确的天级分区
-
--- 💡 为什么使用复数形式？
--- 避免与SQL标准函数year(), month()等冲突
--- 提供更清晰的语义：years = 年数，而不是提取年份
--- 返回值是计算后的数值：days('2024-06-01') = 19875
--- years('2024-06-01') = 54（从1970年开始计算的年份偏移）
-```
-
-**迁移时的理解要点**：
-
-* `years/months/days/hours` 是复数形式，语义更准确
-* 转换分区避免逻辑冲突，确保分区策略的一致性
-* 返回值是计算后的数值，系统自动处理转换逻辑
-* 时间函数计算基准：years 从 1970 年开始，days 从 1970-01-01 开始
-
-#### 2. **隐藏分区的自动优化**
-
-**创新价值**：用户无需关心分区实现细节，专注业务逻辑
-
-```sql
--- ✅ Lakehouse中的简洁查询
-SELECT * FROM sales WHERE order_date = '2024-06-01';  
--- 系统自动转换为分区条件，无需手动指定分区
-
--- 🎯 对比传统方式的优势
--- 1. 查询更简洁，无需复杂的分区条件
--- 2. 分区策略变更不影响查询逻辑
--- 3. 系统自动选择最优的分区扫描策略
-```
-
-#### 3. **智能分区数量控制**
-
-**设计理念**：分区数量限制是性能保护机制，鼓励更好的分区设计
-
-```sql
--- 💡 Lakehouse的分区哲学：质量优于数量
--- 传统思维：尽可能细分分区
--- Lakehouse理念：合理分区粒度 + 索引优化
-
--- ✅ 推荐的高效设计
-CREATE TABLE user_events (
-    event_id INT,
-    user_id INT,
-    event_data JSON,
-    event_time TIMESTAMP_LTZ
-) PARTITIONED BY (days(event_time));  -- 时间分区（主要）
-
-CREATE BLOOMFILTER INDEX idx_user ON TABLE user_events(user_id);  -- 索引优化（辅助）
-
--- 🎯 优势：避免小文件问题，确保每个分区有足够数据量
--- 📊 限制说明：建议单次操作控制在合理范围内，避免过多小分区
-```
-
-#### 4. **转换分区的逻辑一致性**
-
-**设计原则**：避免冲突的分区维度，确保分区逻辑清晰
-
-< '2025-01-01'  -- 年级过滤
-```
-
-#### 5. **类型安全的分区设计**
-
-**安全保障**：通过类型检查避免数据写入错误
-
-```sql
--- 💡 Lakehouse的类型安全机制
-CREATE TABLE orders (
-    id INT,
-    amount DOUBLE
-) PARTITIONED BY (order_date STRING);  -- 明确的STRING类型
-
--- ⚠️ 类型不匹配会报错
-INSERT INTO orders VALUES (1, 100.0, '2024-06-01');  -- 字符串写入STRING分区：正确
-INSERT INTO orders VALUES (1, 100.0, DATE('2024-06-01'));  -- DATE写入STRING分区：错误
-
--- ✅ 推荐做法：使用转换分区避免类型问题
-CREATE TABLE orders_safe (
-    id INT,
-    amount DOUBLE,
-    order_timestamp TIMESTAMP_LTZ
-) PARTITIONED BY (days(order_timestamp));  -- 让系统处理类型转换
-```
-
-### 🔄 **认知升级：从复杂到简洁**
-

-## 🔍 **分区表创建验证（最佳实践**）
-
-### ⚡ **创建后验证：确保分区表正确生效**
-
-无论使用什么方式创建分区表（SQL、工具、脚本），都建议创建后立即验证。这是确保分区功能正常的最佳实践。
-
-#### 推荐的创建和验证流程
-
-```sql
--- 1. 创建分区表（推荐使用原生SQL以确保语法准确）
-CREATE TABLE orders_partitioned (
-    id INT,
-    amount DOUBLE,
-    order_date DATE
-) PARTITIONED BY (days(order_date));
-
--- 2. 立即验证分区表是否正确创建（必做步骤）
-SHOW PARTITIONS orders_partitioned;
--- ✅ 正确：显示分区列表或空列表
--- ❌ 异常：报错 "not a partitioned table"
-```
-
-#### 完整验证清单（每次创建后执行）
-
-```sql
--- 🔍 验证步骤1：确认是分区表
-SHOW PARTITIONS orders_partitioned;
-
--- 🔍 验证步骤2：测试数据插入和分区创建
-INSERT INTO orders_partitioned VALUES (1, 100.50, DATE('2024-06-01'));
-SHOW PARTITIONS orders_partitioned;
--- ✅ 正确：显示类似 "days(order_date)=19875" 的分区
-
--- 🔍 验证步骤3：验证分区裁剪生效
-SELECT * FROM orders_partitioned WHERE order_date = '2024-06-01';
--- 应该能正常返回数据，且性能良好
-
--- 🔍 验证步骤4：检查表结构
-DESCRIBE TABLE orders_partitioned;
--- 确认列结构正确，分区字段类型匹配
-
--- 🔍 验证步骤5：测试最大分区获取（兼容性验证）
-SELECT max_pt('orders_partitioned');
--- 应该返回最大的分区值，用于兼容原平台的类似功能
-```
-
-#### 验证失败时的解决方案
-
-| 验证失败现象                      | 可能原因          | 解决方案       |
-| --------------------------- | ------------- | ---------- |
-| `not a partitioned table`   | 建表语法错误或工具创建异常 | 用原生SQL重新创建 |
-| `implicit cast not allowed` | 分区字段类型不匹配     | 检查插入数据类型   |
-| 无分区显示                       | 分区函数语法错误      | 检查是否用了复数形式 |
-| 性能无提升                       | 查询未利用分区字段     | 优化WHERE条件  |
-
-**为什么需要验证**？
-
-* 确保分区定义语法正确，避免性能问题
-* 及早发现配置错误，减少后续排查成本
-* 验证分区策略是否符合查询模式
-

-
-## 📊 **SHOW PARTITIONS 完整功能指南**
-
-### **基础语法和高级用法**
-
-```sql
--- 完整语法
-SHOW PARTITIONS [EXTENDED] table_name 
-[ PARTITION ( partition_col_name = partition_col_val [, ...] ) ] 
-[WHERE <expr>
-
-### **基础用法**
-
-```sql
--- 查看所有分区
-SHOW PARTITIONS sales_table;
-
--- 查看分区详细信息
-SHOW PARTITIONS EXTENDED sales_table;
-
--- 查看特定分区
-SHOW PARTITIONS sales_table PARTITION (pt1 = '2023');
-
--- 多级分区过滤
-SHOW PARTITIONS sales_table PARTITION (pt1 = '2023', pt2 = '01');
-
--- 限制返回数量
-SHOW PARTITIONS EXTENDED sales_table LIMIT 10;
-```
-
-### **高级用法：分区健康检查神器**
-
-⚠️ **重要限制**：`SHOW PARTITIONS` 不支持 `ORDER BY` 子句，如需排序请使用 WITH 子查询。
-
-< 100*1024*1024;
-
--- 🔍 分区信息查看（支持LIMIT）
-SHOW PARTITIONS EXTENDED table_name LIMIT 10;
-
--- 🔍 分区排序（通过WITH子查询实现）
-WITH partition_info AS (
-    SELECT partitions, bytes, total_rows, total_files, created_time
-    FROM (SHOW PARTITIONS EXTENDED table_name)
-)
-SELECT * FROM partition_info ORDER BY CAST(bytes AS BIGINT) DESC LIMIT 10;
-```
-
-### **MAX_PT 函数 - 获取最新分区**
-
-```sql
--- 💡 MAX_PT函数：获取分区表中最大分区的值
--- 语法：max_pt('schema_name.table_name' | 'table_name')
-
--- 基本用法：查询最新分区的数据
-SELECT * FROM sales_table WHERE pt = max_pt('sales_table');
-
--- 跨schema使用
-SELECT max_pt('prod_schema.sales_table');
-
--- 实际应用场景：
--- 1. 增量数据处理：总是处理最新分区
-INSERT INTO target_table 
-SELECT * FROM source_table 
-WHERE pt = max_pt('source_table');
-
--- 2. 数据质量检查：检查最新分区的数据质量
-SELECT COUNT(*), AVG(amount), MAX(created_time)
-FROM orders 
-WHERE pt = max_pt('orders');
-```
-
-**MAX_PT 函数的迁移价值**：
-
-* **MaxCompute用户**：直接替代原有的max\_pt函数，无需修改查询逻辑
-* **Hive用户**：简化复杂的最大分区查询，提高开发效率
-* **其他平台用户**：提供便捷的最新数据查询方式
-
-***
-
-## 🏗️ **高级分区表创建指南**
-
-### **分区 + 分桶 + 排序组合**
-
-```sql
--- ✅ 方案1：分区 + 分桶（推荐用于散列分布）
-CREATE TABLE events_clustered (
-    user_id INT,
-    event_type STRING,
-    event_data JSON,
-    event_time TIMESTAMP_LTZ
-) PARTITIONED BY (days(event_time))
-  CLUSTERED BY (user_id) INTO 32 BUCKETS;
-
--- ✅ 方案2：分区 + 排序（推荐用于范围查询）
-CREATE TABLE events_sorted (
-    user_id INT,
-    event_type STRING,
-    event_data JSON,
-    event_time TIMESTAMP_LTZ
-) PARTITIONED BY (days(event_time))
-  SORTED BY (event_type);
-
-CREATE TABLE events_both
-(
-    user_id INT,
-    event_type STRING,
-    event_data JSON,
-    event_time TIMESTAMP_LTZ
-)
- PARTITIONED BY (days(event_time))
-CLUSTERED BY (user_id) 
-SORTED BY (event_type)
-INTO 32 BUCKETS;
-```
-
-### **bucket函数使用指南**
-
-**参数范围和建议**：
-
-```sql
--- ✅ 推荐的bucket数量范围
-CREATE TABLE sales PARTITIONED BY (
-    days(sale_date),
-    bucket(10, user_id)    -- 推荐：1-1000的合理范围
-);
-
--- 📊 bucket数量选择指南：
--- 1-10个桶：适合小数据量表（<100万行）
--- 10-100个桶：适合中等数据量表（100万-1000万行）
--- 100-1000个桶：适合大数据量表（>
-
-### **复杂数据类型支持**
-
-```sql
--- ✅ Lakehouse支持所有现代数据类型的分区
-CREATE TABLE modern_table (
-    user_id INT,
-    user_profile STRUCT<name: STRING, age: INT, location: STRING>,
-    tags ARRAY<STRING>,
-    metadata MAP<STRING, STRING>,
-    config JSON,
-    created_date DATE,
-    created_timestamp TIMESTAMP_LTZ,
-    created_timestamp_ntz TIMESTAMP_NTZ
-) PARTITIONED BY (days(created_date));
-
--- 📝 支持的分区字段类型：
--- 基础类型：INT, BIGINT, STRING, DATE, TIMESTAMP_LTZ, TIMESTAMP_NTZ
--- 转换分区：years(), months(), days(), hours(), bucket()
--- 不支持：STRUCT, ARRAY, MAP, JSON作为直接分区字段
-```
-
-### **分区值的特殊情况处理**
-
-```sql
--- 💡 NULL值分区处理
-CREATE TABLE user_regions (
-    user_id INT,
-    region STRING  -- 允许NULL值
-) PARTITIONED BY (region);
-
-INSERT INTO user_regions VALUES (1, NULL);
--- 结果：创建 region=NULL 的分区
-
--- 💡 特殊字符支持
-INSERT INTO user_regions VALUES 
-(2, 'beijing'),           -- 正常字符
-(3, 'shang-hai'),         -- 支持破折号
-(4, 'guang_zhou'),        -- 支持下划线  
-(5, 'xi an'),             -- 支持空格
-(6, 'very_long_city_name_with_many_characters');  -- 支持长字符串
-
--- 查看分区结果
-SHOW PARTITIONS user_regions;
--- 结果显示：region=NULL, region=beijing, region=shang-hai, 等等
-
--- 📝 特殊字符支持总结：
--- ✅ 支持：字母、数字、下划线、破折号、空格、中文
--- ✅ 长度：支持很长的分区值（测试过100+字符）
--- ⚠️ 建议：避免使用特殊符号如@#$%等，虽然可能支持但不推荐

-## 复杂分区迁移策略
-
-### 🏗️ **多级分区架构迁移挑战**
-
-如果您在原平台上已经实现了复杂的分区策略，迁移到Lakehouse时会遇到架构限制和设计选择问题。
-
-
-
-#### 复合维度分区的迁移挑战
-
-**原平台的复合分区**：
-
-```sql
--- MaxCompute/Hive中常见的复合分区
-CREATE TABLE sales PARTITIONED BY (
-    dt STRING,           -- 日期：20240601
-    region STRING,       -- 地区：beijing, shanghai
-    channel STRING       -- 渠道：online, offline
-);
-
--- 分区数量 = 日期数 × 地区数 × 渠道数
--- 例如：365 × 10 × 3 = 10,950个分区/年
-```
-
-**❌ 直接迁移的问题**：
-
-<= '2024-06-30'  -- 分区裁剪
-  AND region = 'beijing'                     -- 索引加速
-  AND channel = 'online';                    -- 索引加速
-```
-
-**策略2：散列分区重设计**
-
-```sql
--- 使用散列函数减少分区数量
-CREATE TABLE sales (
-    sale_id INT,
-    amount DOUBLE,
-    region STRING,
-    channel STRING,
-    sale_date DATE
-) PARTITIONED BY (
-    days(sale_date),           -- 时间分区
-    bucket(10, region)         -- 地区散列到10个桶
-);
-
--- 分区数量 = 365 × 10 = 3,650个分区/年（可控）
-```
-
-### 🔄 **分区演化和维护策略迁移**
-
-#### 动态分区管理的差异
-
-**原平台的分区管理**：
-
-```sql
--- Hive中的分区管理
--- 1. 动态分区自动创建
-INSERT OVERWRITE TABLE target PARTITION(dt, region)
-SELECT ..., dt, region FROM source;  -- 自动创建所有dt×region组合
-
--- 2. 分区修复
-MSCK REPAIR TABLE target;  -- 自动发现新分区
-
--- 3. 分区删除
-ALTER TABLE target DROP PARTITION (dt<'20240101');  -- 批量删除
-```
-
-**Lakehouse中的等价实现**：
-
-```sql
--- 1. 动态分区创建（需要注意分区数量）
--- 建议先检查分区数量
-SELECT COUNT(DISTINCT CONCAT(dt, '/', region)) FROM source;
-
--- 分批处理（如果数量较多）
-INSERT INTO target 
-SELECT ..., dt, region FROM source 
-WHERE dt BETWEEN '20240601' AND '20240615';
-
--- 2. 分区发现（自动完成，无需手动修复）
--- Lakehouse自动管理分区元数据
-
--- 3. 分区清理（功能更强大）
-TRUNCATE TABLE target PARTITION (dt = '20240101');
-```
-
-#### 分区生命周期管理迁移
-
-**MaxCompute的自动生命周期**：
-
-```sql
--- MaxCompute中设置表级生命周期
-ALTER TABLE events SET LIFECYCLE 90;  -- 90天后自动删除
-
--- 分区级生命周期
-ALTER TABLE events PARTITION(dt='20240101') SET LIFECYCLE 30;  -- 单分区30天
-```
-
-**Lakehouse中的分区清理功能**：
-
-```sql
--- 基础分区清理（针对STRING分区）
-TRUNCATE TABLE events PARTITION (dt = '20240101');
-
--- 转换分区清理（需要使用具体分区值）
-TRUNCATE TABLE events_with_days PARTITION (days(event_date) = 19875);
-
--- ✅ 高级功能：条件过滤清理
--- 删除90天前的所有分区（需要先计算具体分区值）
--- 对于STRING分区：
-TRUNCATE TABLE events 
-PARTITION (dt < date_format(date_sub(current_date(), 90), 'yyyyMMdd'));
-
--- 复合条件清理：删除特定日期和地区的数据
-TRUNCATE TABLE sales 
-PARTITION (days(sale_date) = 19875 AND region = 'beijing');
-
--- 批量分区清理：同时清理多个分区
-TRUNCATE TABLE logs 
-PARTITION (days(log_date) = 19875), 
-PARTITION (days(log_date) = 19876);
-```
-
-**分区清理最佳实践**：
-
-```sql
--- 1. 清理前先检查要删除的分区
-SHOW PARTITIONS EXTENDED table_name 
-WHERE dt < '2024-01-01';
-
--- 2. 分阶段清理大量分区（避免长时间锁表）
--- 对于STRING分区：
-TRUNCATE TABLE large_table 
-PARTITION (dt = '20230101');
--- 然后继续清理下一天的数据
-
--- 对于转换分区，需要先查询分区值：
--- SELECT days('2023-01-01'); -- 获取具体分区值
-TRUNCATE TABLE large_table_with_days
-PARTITION (days(date_col) = 具体分区值);
-
--- 3. 定期清理调度脚本示例
--- 每日凌晨2点执行，清理30天前的分区（STRING分区）
-TRUNCATE TABLE daily_logs 
-PARTITION (dt < date_format(date_sub(current_date(), 30), 'yyyyMMdd'));
-```
-
-### 🎯 **性能优化策略的迁移**
-
-#### Z-Order优化的等价实现
-
-**Databricks Delta Lake的Z-Order**：
-
-```sql
--- Delta Lake中的多维优化
-OPTIMIZE events ZORDER BY (user_id, event_type, timestamp);
--- 实现多个字段的联合优化
-```
-
-**Lakehouse中的等价策略**：
-
-```sql
--- 策略1：分区+分桶组合（推荐）
-CREATE TABLE events (
-    user_id INT,
-    event_type STRING,
-    event_data JSON,
-    timestamp TIMESTAMP_LTZ
-) PARTITIONED BY (days(timestamp))    -- 时间分区
-  CLUSTERED BY (user_id) INTO 32 BUCKETS;  -- 用户散列分桶
-
--- 策略2：分区+排序组合
-CREATE TABLE events_sorted (
-    user_id INT,
-    event_type STRING,
-    event_data JSON,
-    timestamp TIMESTAMP_LTZ
-) PARTITIONED BY (days(timestamp))    -- 时间分区
-  SORTED BY (event_type);             -- 事件类型排序
-
--- 策略3：重写优化（类似OPTIMIZE）
-INSERT OVERWRITE events 
-SELECT * FROM events 
-ORDER BY user_id, event_type, timestamp;  -- 手动重排数据
-```
-
-#### 分区裁剪优化的迁移
-
-**原平台的分区裁剪逻辑**：
-
-```sql
--- Spark中的复杂分区过滤
-df.filter(
-    (col("year") >
-
-**Lakehouse 中的等价查询**：
-
-< '2024-09-01'            -- month <= 8  
-  AND region = 'beijing';                  -- region = "beijing"
-
--- 💡 关键：将复杂的分区逻辑转换为简单的时间范围查询
-```
-
-***
-
-## 分平台迁移注意事项
-
-### 🐘 **Hive用户特别注意**
-
-#### 语法兼容性差异
-
-```sql
--- ✅ Hive语法在Lakehouse中仍然支持
-CREATE TABLE hive_style (
-    order_id INT,
-    amount DOUBLE
-) PARTITIONED BY (dt STRING, region STRING);  -- 完全兼容
-
--- ⚠️ 但要注意ADD COLUMN的位置问题
--- Hive: 新列会加到分区列之前的最后位置
--- Lakehouse: 建议明确指定列位置
-ALTER TABLE hive_style ADD COLUMN new_col STRING AFTER amount;  -- 明确指定位置
-```
-
-#### 动态分区配置差异
-
-```sql
--- Hive中需要的配置在Lakehouse中不需要
--- set hive.exec.dynamic.partition=true;           -- Lakehouse中不需要
--- set hive.exec.dynamic.partition.mode=nonstrict; -- Lakehouse中不需要
-
--- 但要注意分区数量管理
--- Hive: hive.exec.max.dynamic.partitions=1000（可调）
--- Lakehouse: 建议单次操作控制在合理范围内
-```
-
-#### Hive用户的真实痛点补充
-
-```sql
--- Hive用户常遇到的额外问题：
--- 1. 分区字段类型限制
-CREATE TABLE hive_table PARTITIONED BY (dt STRING); -- Hive分区字段通常必须是STRING
-
--- 2. 分区目录结构依赖
--- Hive严格依赖 /data/table/year=2024/month=06/day=01/ 这样的目录结构
--- Lakehouse中无此限制，更灵活
-
--- 3. 分区修复的频繁需求
--- Hive: MSCK REPAIR TABLE table_name;  -- 经常需要手动修复
--- Lakehouse: 自动维护元数据，无需手动修复
-```
-
-### ⚡ **Spark用户特别注意**
-
-#### DataFrame写入方式差异
-
-```sql
--- Spark DataFrame常见写入方式
--- df.write.mode("overwrite").partitionBy("date", "region").saveAsTable("table")
-
--- 迁移到Lakehouse SQL时需要注意
--- 1. 确保表已经创建并正确分区
-CREATE TABLE spark_migrated PARTITIONED BY (date STRING, region STRING);
-
--- 2. 使用INSERT语句而不是saveAsTable
-INSERT OVERWRITE spark_migrated SELECT * FROM source_data;
-```
-
-#### 转换函数名映射
-
-| Spark函数          | Lakehouse函数   | 说明     |
-| ---------------- | ------------- | ------ |
-| `year(col)`      | `years(col)`  | 注意复数形式 |
-| `month(col)`     | `months(col)` | 注意复数形式 |
-| `dayofyear(col)` | `days(col)`   | 函数名不同  |
-| `hour(col)`      | `hours(col)`  | 注意复数形式 |
-
-#### Spark用户的额外挑战
-
-```scala
-// Spark用户更常遇到的问题：
-// 1. 分区发现问题
-spark.sql("MSCK REPAIR TABLE table_name")  // Spark也有这个问题
-
-// 2. 动态分区写入的性能陷阱
-df.write.mode("append")
-  .option("maxRecordsPerFile", "50000")  // 控制文件大小
-  .partitionBy("date")
-  .saveAsTable("table")
-
-// 3. 分区列自动推断类型问题
-df.write.partitionBy($"date".cast("string"))  // 必须转string
-```
-
-### ☁️ **MaxCompute用户特别注意**
-
-#### 分区使用习惯调整
-
-```sql
--- MaxCompute强制要求分区条件
--- SELECT * FROM table WHERE pt='20240601';  -- 必须带分区条件，否则报错
-
--- Lakehouse中分区条件是自动的
-SELECT * FROM table WHERE order_date='2024-06-01';  -- 自动分区裁剪，更灵活
-
--- ⚠️ 但仍然建议在查询中包含分区条件以获得最佳性能
-```
-
-#### 生命周期管理差异
-
-```sql
--- MaxCompute的自动生命周期
--- ALTER TABLE table SET LIFECYCLE 30;  -- 30天后自动删除
-
--- Lakehouse中需要手动管理或通过调度
-TRUNCATE TABLE table PARTITION (order_date = '2024-05-01');  -- 手动清理
-```
-
-#### MaxCompute用户的真实痛点
-
-```sql
--- MaxCompute用户最常遇到的问题：
--- 1. 强制分区过滤的习惯
--- MaxCompute: 不带分区条件会直接报错
--- Lakehouse: 允许全表扫描，但建议带分区条件
-
--- 2. 分区表的INSERT OVERWRITE语法差异
--- MaxCompute: INSERT OVERWRITE TABLE target PARTITION(dt='20240601')
--- Lakehouse: INSERT OVERWRITE target ...（自动识别分区）
-
--- 3. 跨项目访问语法变化
--- MaxCompute: SELECT * FROM project.table WHERE pt='20240601';
--- Lakehouse: SELECT * FROM catalog.schema.table WHERE pt='20240601';
-```
-
-### ❄️ **Snowflake用户特别注意**
-
-#### 🚨 **主要认知转变：从自动优化到主动分区设计**
-
-**传统Snowflake用户的习惯**：您可能较少关注底层分区设计
-
-```sql
--- 传统Snowflake中的典型使用模式
-CREATE TABLE orders (id INT, amount DOUBLE, order_date DATE);  -- 系统自动管理存储
-ALTER TABLE orders CLUSTER BY (order_date);  -- 设置聚簇键，系统自动微分区管理
-
--- 查询时完全不用考虑分区
-SELECT * FROM orders WHERE amount >
-
-**现代 Snowflake 用户（Iceberg 表）**：语法基本相似，但有细微差异
-
-```sql
--- Snowflake Iceberg表
-CREATE ICEBERG TABLE orders_iceberg PARTITION BY (year(order_date));
-
--- Lakehouse中的对应语法
-CREATE TABLE orders_lakehouse PARTITIONED BY (years(order_date));  -- 注意复数
-```
-
-**迁移到 Lakehouse 的调整**：
-
-```sql
--- ❌ 传统Snowflake思维在Lakehouse中可能不够优化
-CREATE TABLE orders (id INT, amount DOUBLE, order_date DATE);  -- 创建了普通表，不是分区表
--- 结果：查询性能可能不够理想
-
--- ✅ 学会主动设计分区策略
-CREATE TABLE orders (
-    id INT, 
-    amount DOUBLE,
-    order_date DATE
-) PARTITIONED BY (days(order_date));  -- 主动设计分区
-
--- 查询时虽然自动裁剪，但分区设计直接影响性能
-SELECT * FROM orders 
-WHERE order_date >= '2024-06-01'  -- 分区条件（建议包含）
-  AND amount > 1000;              -- 业务条件
-```
-
-#### Snowflake用户的学习路径
-
-```sql
--- 阶段1：理解分区的价值
--- 分区 = 物理上将数据按某个字段分别存储
--- 目的：查询时只扫描相关分区，而不是全表
-
--- 阶段2：学会分区设计
--- 问自己：我的查询最常用哪个字段做过滤？
--- 时间字段：order_date, created_at, updated_at
--- 业务字段：region, department, customer_type
-
--- 阶段3：验证分区效果
--- 对比分区表 vs 非分区表的查询性能
-```
-
-#### Snowflake用户的认知重点
-
-```sql
--- Snowflake用户需要重点理解：
--- 1. 不是所有数据库都会自动优化
-SELECT * FROM large_table WHERE complex_condition;  -- 需要考虑分区设计
-
--- 2. 分区设计的重要性
--- Snowflake的micro-partitions是自动的，但Lakehouse中需要主动设计
-
--- 3. 文件系统优化概念
--- 理解"小文件问题"、"分区数量控制"等概念
-
--- 4. 查询优化意识
-SELECT * FROM large_partitioned_table 
-WHERE order_date >= '2024-06-01';  -- 包含分区条件的查询习惯
-```
-
-### 🧱 **Databricks 用户特别注意**
-
-#### Delta Lake vs Iceberg差异
-
-```sql
--- Delta Lake的分区语法
--- CREATE TABLE delta_table PARTITIONED BY (year, month);
-
--- Lakehouse (Iceberg)中的等价语法
-CREATE TABLE iceberg_table PARTITIONED BY (years(date_col));  -- 只能用单一时间粒度
-
--- ⚠️ 不能像Delta Lake那样同时使用多个时间粒度
-```
-
-#### 优化命令差异
-
-```sql
--- Delta Lake的优化命令
--- OPTIMIZE table_name;
--- OPTIMIZE table_name ZORDER BY (col1, col2);
-
--- Lakehouse中通过重写实现类似效果
-INSERT OVERWRITE table_name SELECT * FROM table_name;  -- 文件合并优化
-```
-
-#### Databricks用户的高级功能迁移
-
-```sql
--- Databricks用户更常遇到的问题：
--- 1. Delta Lake的时间旅行习惯
--- Delta: SELECT * FROM table TIMESTAMP AS OF '2024-01-01 00:00:00';
--- Lakehouse: SELECT * FROM table TIMESTAMP AS OF '2024-01-01 00:00:00';  -- 语法相似
-
--- 2. OPTIMIZE和Z-ORDER的重度依赖
--- Delta: OPTIMIZE table ZORDER BY (col1, col2);  -- 这是日常操作
--- Lakehouse: 需要通过分区+排序+分桶组合实现
-
--- 3. Unity Catalog的影响
--- Delta: CREATE TABLE catalog.schema.table;  -- 三层命名空间习惯
--- Lakehouse: CREATE TABLE schema.table;  -- 两层命名空间
-```

-## 实战避坑指南
-
-### 分区创建避坑
-
-#### Do's and Don'ts 对比
-
-```sql
--- ❌ 错误做法：不明确的分区设计
-CREATE TABLE bad_partition (
-    id INT,
-    data STRING,
-    timestamp_col TIMESTAMP_LTZ
-);  -- 没有PARTITIONED BY，不是分区表
-
-INSERT INTO bad_partition VALUES (1, 'test', CURRENT_TIMESTAMP());
--- 后面发现查询慢，再想加分区就晚了
-
--- ✅ 正确做法：提前规划分区策略
-CREATE TABLE good_partition (
-    id INT,
-    data STRING,
-    timestamp_col TIMESTAMP_LTZ
-) PARTITIONED BY (days(timestamp_col));
-
--- 立即验证分区是否正确创建
-SHOW PARTITIONS good_partition;  -- 应该能正常执行，不报错
-```
-
-#### 分区字段类型选择
-
-```sql
--- ❌ 容易踩坑的类型选择
-CREATE TABLE date_type_trap (
-    id INT,
-    order_date DATE  -- DATE类型
-) PARTITIONED BY (order_date);
-
--- 插入数据时可能报类型错误
-INSERT INTO date_type_trap VALUES (1, '2024-06-01');  -- 字符串vs DATE类型
-
--- ✅ 推荐做法：使用STRING类型分区
-CREATE TABLE string_partition (
-    id INT,
-    order_date_str STRING  -- 用STRING类型避免类型转换问题
-) PARTITIONED BY (order_date_str);
-
--- 或者使用转换分区
-CREATE TABLE transform_partition (
-    id INT,
-    order_date DATE
-) PARTITIONED BY (days(order_date));  -- 让系统处理类型转换
-```
-
-### 数据写入避坑
-
-#### 大批量写入策略
-
-<= 'end_value';
-```
-
-#### 分区数据一致性
-
-```sql
--- ⚠️ 注意：转换分区的时区问题
-CREATE TABLE timezone_sensitive (
-    id INT,
-    event_time TIMESTAMP_LTZ  -- 带时区的时间戳
-) PARTITIONED BY (days(event_time));
-
--- 不同时区的相同本地时间可能落在不同分区
-INSERT INTO timezone_sensitive VALUES 
-(1, TIMESTAMP '2024-06-01 23:30:00 UTC'),      -- UTC时区
-(2, TIMESTAMP '2024-06-01 23:30:00');          -- 系统默认时区
-
--- 查看分区分布
-SHOW PARTITIONS timezone_sensitive;
--- 可能看到两个不同的分区值：days(event_time)=19875 和 days(event_time)=19876
-```
-
-### 查询性能避坑
-
-#### 分区裁剪失效场景
-
-```sql
--- ❌ 无法利用分区裁剪的查询
-SELECT * FROM partitioned_table 
-WHERE YEAR(order_date) = 2024;  -- 函数包装分区字段
-
-SELECT * FROM partitioned_table 
-WHERE order_date LIKE '2024%';  -- 模糊匹配
-
--- ✅ 能够有效分区裁剪的查询
-SELECT * FROM partitioned_table 
-WHERE order_date >
-
-### 🚨 **分区故障快速排查**
-
-#### 问题：分区表性能比非分区表还差
-
-**排查命令**：
-
-< 10*1024*1024;
-
--- 4. 检查查询是否利用分区
-EXPLAIN SELECT * FROM your_table WHERE partition_col = 'value';
-```
-
-**常见原因和解决方案**：
-
-* **过度分区（分区太小太多**） → 重新设计分区粒度
-* **查询未包含分区字段** → 优化查询WHERE条件
-* **创建的不是真正的分区表** → 用原生SQL重建
-
-***
-
-## 分区性能验证实战指南
-
-### 🎯 **分区效果验证的标准方法**
-
-#### 1. 创建对比测试
-
-```sql
--- 创建相同数据的分区表和非分区表
-CREATE TABLE sales_partitioned (
-    id INT, amount DOUBLE, sale_date DATE
-) PARTITIONED BY (days(sale_date));
-
-CREATE TABLE sales_normal (
-    id INT, amount DOUBLE, sale_date DATE
-);
-
--- 插入相同的大量数据（建议>
-
-#### 2. 性能基准测试
-
-<= '2024-06-30';
-```
-
-#### 3. 分区健康检查
-
-```sql
--- 检查分区大小分布
-SHOW PARTITIONS EXTENDED table_name;
-
--- 理想状态：
--- ✅ 每个分区 128MB - 1GB
--- ✅ 分区大小相对均匀
--- ❌ 大量小于10MB的小分区
--- ❌ 单个分区超过5GB
-```
-
-### 📊 **性能问题诊断**
-
-#### 分区表比非分区表还慢？
-
-**可能原因与解决方案**：
-
-1. **过度分区**：分区太细，元数据开销大
-   ```sql
-   -- 问题：每小时分区，导致大量小分区
-   PARTITIONED BY (hours(timestamp))
-
-   -- 解决：改为天级分区
-   PARTITIONED BY (days(timestamp))
-   ```
-
-2. **查询未利用分区**：WHERE条件没有包含分区字段
-   ```sql
-   -- ❌ 无法利用分区
-   SELECT * FROM partitioned_table WHERE amount >
-
-3. **分区字段选择错误**：分区字段不是查询热点
-   ```sql
-   -- 问题分析：检查查询模式
-   -- 如果查询主要按user_id过滤，但按date分区，效果不佳
-
-   -- 解决：重新设计分区策略
-   PARTITIONED BY (bucket(100, user_id))  -- 改按用户散列分区
-   ```
-
-### 🎛️ **分区调优实战**
-
-#### 1. 分区粒度选择
-
-< 10K：月级分区 months()
-```
-
-#### 2. 复合分区优化
-
-```sql
--- 原始复合分区问题
-CREATE TABLE sales_old PARTITIONED BY (region, sale_date, channel);
--- 问题：10个地区 × 365天 × 3渠道 = 10,950分区
-
--- 优化方案1：主次分区
-CREATE TABLE sales_optimized (
-    ..., region STRING, channel STRING
-) PARTITIONED BY (days(sale_date));  -- 主分区：时间
-CREATE BLOOMFILTER INDEX idx_region ON TABLE sales_optimized(region);
-CREATE BLOOMFILTER INDEX idx_channel ON TABLE sales_optimized(channel);
-
--- 优化方案2：散列压缩
-CREATE TABLE sales_hash PARTITIONED BY (
-    days(sale_date),           -- 时间分区：365个
-    bucket(5, region)          -- 地区散列到5个桶
-);
--- 结果：365 × 5 = 1,825分区（可控）
-```
-
-#### 3. 分区演化策略
-
-```sql
--- 定期分区健康检查
-WITH partition_health AS (
-    SELECT 
-        partitions,
-        total_rows,
-        bytes,
-        CASE 
-            WHEN CAST(bytes AS BIGINT) < 10*1024*1024 THEN 'TOO_SMALL'
-            WHEN CAST(bytes AS BIGINT) >
-
-#### 迁移效果对比
-
-<= '2024-06-01 17:59:59';
-
--- 性能提升：
--- 📈 查询速度：提升40%（避免小分区扫描）
--- 🔧 维护成本：降低60%（分区数量大幅减少）
--- 📝 查询复杂度：降低80%（无需计算年月日时）
-```
-
-### 📋 **案例2：日志分析表迁移（MaxCompute → 云器Lakehouse**）
-
-#### 原始MaxCompute表
-
-```sql
--- 原MaxCompute表：严格分区限制
-CREATE TABLE app_logs (
-    user_id STRING,
-    event_type STRING,
-    event_data STRING
-) PARTITIONED BY (
-    pt STRING,          -- 格式：20240601  
-    region STRING,      -- 地区：beijing, shanghai
-    app_version STRING  -- 版本：1.0, 1.1, 1.2
-);
-
--- MaxCompute特点：
--- ✅ 强制分区条件：SELECT必须带WHERE pt='20240601'
--- ❌ 分区数量爆炸：365 × 10 × 20 = 73,000/年
--- ❌ 数据倾斜：北京地区数据多，其他地区很少
-```
-
-#### 云器Lakehouse迁移策略
-
-```sql
--- 步骤1：分析原有查询模式
--- 发现：90%查询都是按时间范围 + 地区过滤
--- 决策：时间作为主分区，地区用索引
-
--- 步骤2：重设计分区架构
-CREATE TABLE app_logs_new (
-    user_id STRING,
-    event_type STRING,
-    event_data STRING,
-    region STRING,        -- 不分区，用索引
-    app_version STRING,   -- 不分区，用索引
-    log_date DATE
-) PARTITIONED BY (days(log_date));  -- 只按时间分区
-
--- 步骤3：创建索引优化非分区查询
-CREATE BLOOMFILTER INDEX idx_region ON TABLE app_logs_new(region);
-CREATE BLOOMFILTER INDEX idx_version ON TABLE app_logs_new(app_version);
-
--- 步骤4：验证查询性能
--- 原查询：
-SELECT * FROM app_logs WHERE pt='20240601' AND region='beijing';
-
--- 新查询：
-SELECT * FROM app_logs_new 
-WHERE log_date='2024-06-01' AND region='beijing';
--- 结果：性能相当，但分区数量从73000降至365
-```
-
-#### 迁移过程中的挑战
-
-```sql
--- 挑战1：数据类型不一致
--- MaxCompute: pt STRING '20240601'
--- 云器Lakehouse: log_date DATE '2024-06-01'
-
--- 解决：ETL转换脚本
-INSERT INTO app_logs_new 
-SELECT 
-    user_id,
-    event_type, 
-    event_data,
-    region,
-    app_version,
-    DATE(CONCAT(
-        SUBSTR(pt, 1, 4), '-',
-        SUBSTR(pt, 5, 2), '-', 
-        SUBSTR(pt, 7, 2)
-    )) as log_date
-FROM maxcompute_source;
-
--- 挑战2：习惯性写法需要调整
--- MaxCompute习惯：WHERE pt='20240601'（字符串精确匹配）
--- 云器Lakehouse：WHERE log_date='2024-06-01'（自动分区裁剪）
-
--- 挑战3：最大分区查询方式变化
--- MaxCompute原有：WHERE pt = max_pt()
--- 云器Lakehouse新方法：WHERE log_date = (SELECT DATE(max_pt('app_logs_new')))
--- 或者重新设计为STRING分区，直接使用：WHERE pt = max_pt('app_logs_new')
-```
-
-#### 分区维护自动化
-
-```sql
--- MaxCompute风格的自动化脚本（适应新平台）
--- 1. 每日清理30天前的分区
-TRUNCATE TABLE app_logs_new 
-PARTITION (log_date < current_date() - INTERVAL '30' DAY);
-
--- 2. 智能清理：保留最新分区，清理小分区
-WITH old_partitions AS (
-    SELECT partitions
-    FROM (SHOW PARTITIONS EXTENDED app_logs_new)
-    WHERE CAST(bytes AS BIGINT) < 1000000  -- 小于1MB的分区
-      AND partitions < max_pt('app_logs_new') - INTERVAL '7' DAY
-)
--- 逐个清理小分区（注意：需要具体分区值）
-
--- 3. 分区健康检查脚本
-WITH partition_stats AS (
-    SELECT 
-        partitions,
-        CAST(total_rows AS BIGINT) as rows,
-        CAST(bytes AS BIGINT) as size_bytes
-    FROM (SHOW PARTITIONS EXTENDED app_logs_new)
-)
-SELECT 
-    COUNT(*) as total_partitions,
-    AVG(size_bytes)/1024/1024 as avg_size_mb,
-    SUM(CASE WHEN size_bytes < 10*1024*1024 THEN 1 ELSE 0 END) as small_partitions,
-    max_pt('app_logs_new') as latest_partition
-FROM partition_stats;
-```
-
-### 📋 **案例3：实时数据表迁移（Spark → 云器Lakehouse**）
-
-#### 原始Spark Delta表
-
-```sql
--- 原Spark表：小时级分区 + Z-Order优化
-CREATE TABLE user_events USING DELTA
-PARTITIONED BY (date_hour STRING)  -- 格式：2024060109
-OPTIONS (
-  'path' '/data/user_events'
-);
-
--- 定期优化
-OPTIMIZE user_events ZORDER BY (user_id, event_type);
-```
-
-#### 云器Lakehouse迁移挑战
-
-```sql
--- 挑战1：没有直接的Z-Order等价功能
--- 挑战2：小时级分区可能过细
--- 挑战3：实时写入性能要求高
-
--- 解决方案1：分区 + 分桶组合（推荐）
-CREATE TABLE user_events_new (
-    user_id INT,
-    event_type STRING,
-    event_data JSON,
-    event_time TIMESTAMP_LTZ
-) PARTITIONED BY (hours(event_time))      -- 保持小时级分区（实时需求）
-  CLUSTERED BY (user_id) INTO 32 BUCKETS; -- 用户ID分桶
-
--- 解决方案2：分区 + 排序组合
-CREATE TABLE user_events_sorted (
-    user_id INT,
-    event_type STRING,
-    event_data JSON,
-    event_time TIMESTAMP_LTZ
-) PARTITIONED BY (hours(event_time))      -- 保持小时级分区
-  SORTED BY (event_type);                 -- 事件类型排序
-
--- 实现类似Z-Order的效果：
--- 1. 分区：按时间物理隔离
--- 2. 分桶：按用户ID散列分布  
--- 3. 排序：按事件类型聚集存储
-```
-
-#### 性能调优过程
-
-```sql
--- 调优1：监控分区大小
-WITH partition_analysis AS (
-    SELECT 
-        partitions,
-        CAST(bytes AS BIGINT)/1024/1024 as size_mb,
-        CAST(total_rows AS BIGINT) as row_count
-    FROM (SHOW PARTITIONS EXTENDED user_events_new)
-)
-SELECT * FROM partition_analysis 
-ORDER BY size_mb DESC LIMIT 10;
-
--- 发现问题：夜间分区太小（<10MB）
--- 解决：动态调整分区策略
-
--- 调优2：白天用小时分区，夜间合并
--- 通过ETL实现智能分区策略：
--- 8:00-22:00高峰期：小时级分区
--- 22:00-8:00低峰期：合并到天级分区

-### 📋 **案例4：数据仓库迁移（Snowflake → 云器Lakehouse**）
-
-#### Snowflake用户的特殊挑战
-
-```sql
--- 传统Snowflake：自动存储管理
-CREATE TABLE sales (
-    order_id INT,
-    customer_id INT,
-    amount DECIMAL(10,2),
-    order_date DATE
-);
-
--- 设置聚簇键（用户相对无感知）
-ALTER TABLE sales CLUSTER BY (order_date);
-
--- 查询：不用特别关心物理存储
-SELECT * FROM sales WHERE amount >
-
-#### 云器Lakehouse学习路径
-
-```sql
--- 第1阶段：理解分区概念
--- 问题：什么是分区？为什么需要分区？
--- 答案：分区是将数据按某个字段物理分开存储，查询时只扫描相关分区
-
--- 第2阶段：学会分区设计
--- 问题：应该按什么字段分区？
--- 分析：检查最常用的WHERE条件
-SELECT 
-    COUNT(*) as query_count,
-    'order_date filter' as filter_type
-FROM query_log 
-WHERE query_text LIKE '%WHERE%order_date%'
-UNION ALL
-SELECT 
-    COUNT(*),
-    'customer_id filter' 
-FROM query_log 
-WHERE query_text LIKE '%WHERE%customer_id%';
-
--- 结果：order_date过滤占80%，customer_id占20%
--- 决策：按order_date分区，customer_id用索引
-
--- 第3阶段：正确的分区表设计
-CREATE TABLE sales_partitioned (
-    order_id INT,
-    customer_id INT,
-    amount DECIMAL(10,2),
-    order_date DATE
-) PARTITIONED BY (days(order_date));
-
-CREATE BLOOMFILTER INDEX idx_customer ON TABLE sales_partitioned(customer_id);
-
--- 第4阶段：验证性能提升
--- 对比查询：
-SELECT * FROM sales WHERE order_date = '2024-06-01';           -- 全表扫描
-SELECT * FROM sales_partitioned WHERE order_date = '2024-06-01'; -- 分区扫描
-
--- 结果：分区表通常有显著性能提升
-```
-
-#### Snowflake用户常见调整和实际困惑
-
-```sql
--- 调整1：创建分区表而不是普通表
-CREATE TABLE sales_correct (
-    order_id INT,
-    amount DECIMAL(10,2),
-    order_date DATE
-) PARTITIONED BY (days(order_date));  -- ✅ 这是分区表
-
--- 调整2：查询时包含分区条件
-SELECT * FROM sales_partitioned 
-WHERE order_date >= '2024-06-01'  -- ✅ 利用分区
-  AND amount > 1000;              -- ✅ 业务过滤
-
--- 调整3：理解分区字段的重要性
-SELECT * FROM sales_partitioned WHERE amount > 1000;  -- 可以优化为包含分区条件
-
--- 调整4：不是所有查询都会自动很快
--- Snowflake用户习惯了系统自动处理一切存储优化
--- Lakehouse中需要更多的主动设计意识
-```
-
-#### 认知转变的实际过程
-
-```markdown
-### Snowflake用户的常见疑问：
-"为什么我的查询在Snowflake上很快，在Lakehouse上需要考虑分区？"
-
-**答案**：Snowflake的自动优化 vs Lakehouse的主动分区设计各有优势
-
-### 学习过程中的典型问题：
-1. "为什么要我来决定分区策略？"
-2. "什么是小文件问题？我之前没考虑过文件大小"
-3. "分区数量控制是什么意思？"
-
-### 理解突破时刻：
-当用户看到分区表比非分区表有明显性能优势时，开始理解分区的价值
-```

-## 迁移验证清单
-
-### 📋 **分区创建验证**
-
-```sql
--- ✅ 检查点1：表确实是分区表
-SHOW PARTITIONS your_table_name;
--- 应该能正常执行，不报"not a partitioned table"错误
-
--- ✅ 检查点2：分区字段类型正确
-DESCRIBE TABLE your_table_name;
--- 确认分区字段的数据类型与预期一致
-
--- ✅ 检查点3：测试数据写入
-INSERT INTO your_table_name VALUES (测试数据);
-SHOW PARTITIONS your_table_name;
--- 应该能看到新创建的分区
-
--- ✅ 检查点4：验证分区值格式
--- 转换分区会生成数值，如 days('2024-06-01') = 19875
--- years('2024-06-01') = 54（从1970年开始的年份计数）
--- 确认分区值符合预期
-
--- ✅ 检查点5：测试最大分区获取（兼容性验证）
-SELECT max_pt('your_table_name');
--- 应该返回最大的分区值，用于兼容原平台的类似功能
-```
-
-### 📋 **性能验证**
-
-```sql
--- ✅ 检查点6：分区裁剪是否生效
--- 对比这两个查询的执行时间
-SELECT COUNT(*) FROM your_table_name;  -- 全表扫描
-SELECT COUNT(*) FROM your_table_name WHERE partition_col = 'specific_value';  -- 分区查询
-
--- 分区查询应该明显更快
-
--- ✅ 检查点7：分区大小是否合理
-SHOW PARTITIONS EXTENDED your_table_name;
--- 检查每个分区的大小，理想范围：128MB - 1GB
-```
-
-### 📋 **兼容性验证**
-
-```sql
--- ✅ 检查点8：原有查询语句是否需要修改
--- 将原平台的查询语句在Lakehouse中测试
--- 特别注意：
--- 1. 转换函数名是否需要调整（year -> years）
--- 2. 分区条件是否能自动识别
--- 3. 数据类型转换是否正常
-
--- ✅ 检查点9：分区演化策略是否可行
--- 验证分区清理、维护脚本是否正常工作
-```

-
-### 🛡️ **避坑要点总结**
-
-#### 基础语法陷阱
-
-1. **转换函数名记住复数形式**：`years`, `months`, `days`, `hours`
-2. **分区类型保持一致**：避免STRING和DATE类型混用
-3. **分区数量控制在合理范围**：避免过多小分区
-4. **分区设计考虑查询模式**：根据WHERE条件设计分区字段
-5. **及时验证分区效果**：创建后立即检查分区是否正确
-
-#### 复杂迁移陷阱
-
-6. **多级时间分区不能直接迁移**：`year+month+day`要改为`days()`单一粒度
-7. **复合分区维度要精简**：过多维度会导致分区数量过多
-8. **分区演化策略要重建**：从自动管理改为手动调度管理
-9. **性能优化策略要调整**：Z-Order等高级优化需要重新设计

-16. **bucket函数参数要合理**：推荐使用1-1000范围的正整数
-17. **注意NULL值和特殊字符**：系统会创建对应的分区
-
-### 💡 **成功迁移的经验**
-
-#### 对于简单分区场景
-
-* **渐进式迁移**：先迁移小表验证，再迁移核心大表
-* **保留原有查询逻辑**：尽量让原有SQL无需大改即可工作
-* **性能基准对比**：迁移前后的查询性能对比验证
-* **完整验证流程**：严格按照验证清单执行
-
-#### 对于复杂分区场景
-
-* **分区策略重设计**：不要试图完全复制原有分区结构
-* **性能验证优先**：用代表性查询验证新分区策略的效果
-* **分阶段实施**：复杂迁移分为分析、重设计、测试、切换四个阶段
-* **回退方案准备**：确保迁移失败时能快速回退到原方案
-
-### 🚀 **特别提醒**
-
-**对于 Snowflake 等平台用户**：
-迁移到 Lakehouse 的挑战主要在于思维模式的调整。您需要从"较少关注分区"转变为"主动设计分区策略"。建议先在测试环境中体验分区对查询性能的影响，理解分区的价值，再开始设计生产环境的分区策略。
-
-**对于有复杂分区架构的用户**：
-不要试图在Lakehouse中完全复制原有的分区结构。Lakehouse的分区哲学是"简化而不失性能"。多级分区、复合分区等复杂设计在Lakehouse中往往可以用更简单的方案达到同样或更好的效果。
-
-**对于所有迁移用户**：
-分区表的创建验证是成功迁移的第一步，也是最关键的一步。建议使用原生SQL创建分区表，并严格执行验证清单。很多迁移问题都源于分区表没有正确创建，导致后续的性能优化无从谈起。
-
-记住：**Lakehouse 的分区不是负担，而是性能优化的利器**。正确使用分区，您将获得比原平台更好的查询性能和更灵活的数据管理能力。

-# OPTIMIZE 命令
-
-## 概述
-
-OPTIMIZE 是 ClickZetta Lakehouse 中用于表数据优化和压缩的核心操作命令。通过整合小文件、清理删除标记和重组数据布局，可以显著改善查询性能和存储效率。虽然 Lakehouse 后台会默认定期自动执行文件合并，但在频繁更新或需要精细控制合并频率的场景中，用户可以通过手动调用该命令来满足特定业务需求。该命令支持异步和同步两种执行模式，为不同场景提供灵活的优化方案。
-
-## 命令语法
-
-```sql
-OPTIMIZE table_name 
-[WHERE predicate]  -- 可选分区过滤条件
-[OPTIONS(...)]
-```
-
-1. table_name（必选）
-
-* 需要优化的目标表名称，格式为 `[schema_name.]table_name`
-
-2. WHERE predicate（可选）
-
-* 分区过滤条件，必须包含**完整的分区列匹配条件**。
-* 支持格式：`partition_column = 'value'` 或复合分区 `dt='2023-01-01' AND region='us'`。
-
-3. OPTIONS（可选）
-
-* Lakehouse 保留参数，用于控制优化行为。
-
-## 注意事项
-
-* 该功能只能在**通用型计算集群（GENERAL PURPOSE VIRTUAL CLUSTER）**中运行，在分析型集群中该功能不会生效。
-
-## 核心功能
-
-* **小文件合并**：将多个小数据文件整合为大文件，减少文件元数据开销。
-* **删除标记清理**：清理 UPDATE/DELETE 操作产生的删除标记，回收存储空间。
-* **数据重组**：重新整理数据布局，提升查询性能。
-
-## 执行模式
-
-### 1. 异步执行模式（默认）
-
-异步执行是 OPTIMIZE 的默认行为，操作在后台进行，不阻塞当前连接。
-
-#### 特点
-
-* **非阻塞**：立即返回 Job ID，操作在后台执行。
-
-#### 语法
-
-```sql
--- 默认异步执行
-OPTIMIZE table_name;
-
--- 显式指定异步执行
-OPTIMIZE table_name OPTIONS('cz.sql.optimize.table.async' = 'true');
-```
-
-### 2. 同步执行模式
-
-同步执行会阻塞当前连接，直到优化操作完全完成后才返回结果。
-
-#### 特点
-
-* **阻塞式**：操作完成才返回，期间连接被占用。
-* **实时反馈**：立即获得详细的执行统计和成功状态。
-* **适用场景**：开发测试、小表优化、验证优化效果。
-* **确定性**：确保操作完全完成。
-
-#### 语法
-
-```sql
-OPTIMIZE table_name OPTIONS('cz.sql.optimize.table.async' = 'false');
-```
-
-## 适用场景
-
-* 大量 UPDATE/DELETE 操作后的存储清理
-* 释放临时存储空间的定期维护任务
-* 优化表的总体存储布局

-# PUT 命令
-
-## 简介
-
-PUT 命令是 Lakehouse SQL 中的一个实用工具，用于将客户端主机的本地文件上传到 Lakehouse 数据湖的 Volume 对象中。通过该命令，用户可以轻松地将本地文件传输至云端，实现数据的快速迁移和同步。要执行 PUT 命令，您可以使用 [sqlline](connect-with-cli.md) 工具或 [数据库管理工具](eco_integration/dbeaver-lakehouse.md)。该命令暂不支持在 Studio 中运行。
-
-## 使用场景
-
-PUT 命令适用于以下场景：
-
-1. 将本地文件上传到数据湖 Volume 对象。
-2. 快速迁移和同步本地与云端数据。
-
-## 语法
-
-```
-PUT 'local_path' [ , 'local_path' [ , ... ] ] 
-    TO 
-    [ VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME ]
-    [ SUBDIRECTORY 'dir' | FILE 'filename' ]
-    [ option_key = option_value ] ..
-```
-
-## 参数说明
-
-* `local_path`：本地要上传文件的路径。**Linux / macOS**：路径以根目录 `/` 开始，或者使用 `'file:///'` 前缀表示本地路径。**Windows 系统**：如果目录路径和/或文件名包含特殊字符，则整个文件 URI 必须用单引号括起来。注意，在封闭的 URI 中，分隔符为正斜杠 (`/`)。
-* `VOLUME/TABLE VOLUME/USER VOLUME`：指将本地数据上传至外部 Volume、TABLE VOLUME 或 USER VOLUME。
-* `SUBDIRECTORY/FILE`：指定上传文件的目标路径，可以指定子目录（`SUBDIRECTORY`），也可以利用 FILE 参数对上传的文件进行重命名操作。
-
-## 示例
-
-1. 使用内部 Volume 上传文件到表中
-
-```
---上传文件
-PUT '/Users/Downloads/data.csv' TO TABLE VOLUME my_table FILE 'data.csv';
--- 查看文件
-SHOW TABLE VOLUME DIRECTORY my_table;
---导入文件
-COPY INTO my_table FROM TABLE VOLUME my_table(id int, name string) USING csv  
-OPTIONS(
-        'header'='true',
-        'lineSep'='\n'
-)
-FILES ('data.csv')
---删除volume中的文件，节省存储
-PURGE=TRUE;
-
-```
-
-2. 创建名为 `hz_image_volume` 的外部 Volume 对象，并上传文件 `'/Users/Downloads/cats_and_dogs.zip'`，将其重命名为 catsdogs.zip：
-
-   ```SQL
-   PUT '/Users/Downloads/cats_and_dogs.zip' to VOLUME hz_image_volume FILE 'catsdogs.zip'
-   ```
-
-3. 将本地数据上传至名为 `tbl_region` 的表的 Volume 空间：
-
-   ```SQL
-   PUT '/Users/Downloads/region.tbl' TO TABLE VOLUME tbl_region;
-   ```
-
-## 注意事项
-
-* PUT 命令不能通过 Studio SQL 任务节点执行。用户可以通过 Lakehouse SQLLine 客户端、JDBC 客户端或 SDK 来执行该命令。
-* 请确保上传的单个文件大小不超过 5 GB。
-* 在使用 PUT 命令时，请确保本地文件的路径和文件名正确无误，避免因路径错误导致上传失败。
-* 上传文件时，如果目标 Volume 对象中已存在同名文件，系统将自动覆盖原有文件。如有需要，请在上传前进行相应的备份操作。

-# 在云器 Lakehouse 的同一张表中进行向量和标量检索
-
-## 数据准备
-
-GitHub 提供 15 多种事件类型，包括新提交和分叉事件、打开新工单、评论和向项目添加成员等。这些事件会汇总到每小时存档中，您可以使用任何 HTTP 客户端从 <https://www.gharchive.org/> 上访问这些存档。
-
-* 通过 wget 从 <https://www.gharchive.org/> 将归档的 json.gz 文件下载到本地。本文下载了 2025-01-01 一天的 24 个文件。
-* 通过 Lakehouse 的 PUT 命令，将数据 PUT 到用户卷 (USER VOLUME) 上。
-* 通过 SQL 直接读取用户卷 (USER VOLUME) 目录里的文件，然后将 IssuesEvent 类型的事件写入 `github_event_issuesevent` 表中。
-* 将数据从 github\_event\_issuesevent 写入到目标表 github\_event\_issuesevent\_embedding 中。
-
-## 数据向量化
-
-云器 Lakehouse 的 `github_event_issuesevent_embedding` 表中保存了文本字段，需要对该文本字段进行向量化，并保存在同一张表的向量字段里，方便进行向量和标量的融合检索。
-
-该方案在同一张表、同一个 VCluster 中，同时支持文本数据、向量数据以及倒排索引和向量索引的存储。与传统方式相比，不再需要三套系统（数据仓库、文本检索数据库、向量数据库），最大程度地降低了数据副本数量，避免了数据在三套系统之间的同步。
-
-![](/.topwrite/assets/image_1768390312153.png)
-
-^
-^
-
-### 用到的云器 Lakehouse 关键特性
-
-* [向量存储](vector-type.md)：原生的Vector数据类型，在普通表里直接增加Vector类型的字段；
-* [向量索引](create-table-ddl.md)：对Vector类型的字段建立索引，加速向量检索的速度；
-* [倒排索引](create-table-ddl.md)：对文本字段建立倒排索引，加速文本检索的速度；
-* [bloom\_filter索引](create-table-ddl.md)：对ID字段建立索引，加速ID过滤；
-* [Zettapark](ZettaparkQuickStart.md)
-
-### 模型服务
-
-* xinference，本地部署xinference，提供embedding和rerank模型服务；
-* 本方案采用 1024 维的向量表示。
-
-### 测试数据集介绍
-
-* 数据来源是 GitHub 的 IssuesEvent 事件，全文检索字段为其中的 `issue_body`。
-* 向量字段存储的是 `issue_body` 对应的向量化数据。
-* 全表有 1.9 亿条记录。
-
-### 数据说明
-
-* 表名：`github_event_issuesevent_embedding`
-* 文本字段：`issue_body`，string 类型
-* 向量化字段：`issue_body_embedding`，vector(float,1024) 类型
-* 向量化方法：`issue_body_embedding` 的初始值为 NULL。调用 xinference/ollama 本地服务，用 bge-m3 模型对 `issue_body` 字段的文本进行向量化，然后保存到 `issue_body_embedding` 字段。
-
-### issue\_body\_embedding字段更新方法
-
-* **单条 Update 方法**
-  * 符合传统数据库开发者的习惯，数据更实时，达到秒级数据新鲜度。但是在大数据平台上用 SQL 进行频繁的 UPDATE，会带来明显的弊端：
-    * 带来大量的小文件需要及时进行合并，以优化性能。
-    * 需要一直启动 VCluster，造成计算成本高。
-
-* **批量 Merge Into 方法**
-  * 牺牲了数据新鲜度，从秒级到分钟级。
-  * 规避了小文件急剧增多的问题。
-  * 大幅降低了计算成本，每 5 分钟 MERGE INTO 一次，计算成本下降幅度可达 80%，大幅提升了数据向量化的性价比。这对大数据量的向量化非常重要。
-
-## 融合检索
-
-* 参考并已完成在云器 Lakehouse 的同一张表中进行向量和标量存储。

-Lakehouse 实现了 MySQL 客户端与服务端的通讯协议，因此可以使用 MySQL 驱动连接 Lakehouse。然而，Lakehouse 并未实现 MySQL 的语法和数据类型。您可以通过 MySQL 客户端连接到 Lakehouse，但执行的 SQL 语句应使用 Lakehouse 语法，而非 MySQL 语法。例如，`mysqldump` 命令在 Lakehouse 中不可用。本文使用 PowerBI 中的 MySQL 驱动连接 Lakehouse，快速了解如何连接 Lakehouse。我们使用财务示例数据集。
-
-## 准备工作
-
-* 目前需要重置密码，即使是新建的账号也需要重置密码。这是因为 MySQL 5.x 版本使用的是 `mysql_native_password` 密钥，而 Lakehouse 需要保存 MySQL 的加密算法。目前，只有在修改密码时，Lakehouse 才会保存 MySQL 密钥的加密算法。您可以修改密码时保持和之前一样这样可以避免影响别的任务连接
-
-* 给用户设置计算集群，由于 MySQL 协议中没有传入设置集群的方式，用户可以使用 SQL 命令为用户添加一个默认计算集群。这样在 MySQL 连接时就会使用该集群。需要注意的是，BI场景对分析性能往往有要求，建议为BI工具连接用户选择合适规格的分析型计算集群以提供最佳的查询性能。
-
-  ```SQL
-   ALTER USER user_name SET DEFAULT_VCLUSTER = default_ap;
-    
-   -- 查看集群设置是否生效
-   SHOW USERS;
-  ```
-
-* 准备用户名。 MySQL 协议连接地址时只能传入一个 URL，无法拼接 Lakehouse 的 instance name 和 workspace name，因此需要将 instance name 和 workspace name 拼接到用户名中。
-
-  *   用户名格式要求如下：
-
-  * ```Plain
-    登录的账号名称@instance_name.workspace_name
-    ```
-
-  * **instance\_name 获取**：在 工作空间页面 中获取 JDBC 连接串。例如，在 `jdbc:clickzetta://``jnsxwfyr.api.clickzetta.com/quick_start?virtualCluster=default` 中，`jnsxwfyr` 为 instance\_name。
-
-    * ![](.topwrite/assets/image_1723468458225.png)
-
-  * **workspace\_name 获取**：工作空间的名称。
-
-* 在 Lakehouse 中创建 schema 和 table，并上传数据。
-
-```Plain
-create schema sales;
-use sales;
-create table salesdata (
-    segment varchar(255),
-    country varchar(255),

-## 补数实现全量同步
-
-周期任务从指定的时间开始周期性执行，从而获取数据。为了获取此时间点之前的全量数据，可以直接使用同样的代码和任务，执行“补数”操作，批量同步周期任务第一个调度周期之前的所有数据，从而实现全量同步。这种方式非常方便，并且通过同一套代码保证了逻辑的一致性。
-点击“运维”，进入周期任务的运维页面，然后点击“补数”。
-gharchive 上的文件从 2012-02-12 日开始生成，因此将补数任务的开始时间设置为 2012-02-12 00:00:00。
-该任务的周期调度是从 2024-06-18 日的 11 点开始的，因此将补数任务的结束时间设置为 2024-06-18 11:00:00。
-
-![](.topwrite/assets/image_1718680764715.png)
-
-预览补数任务生成的实例，共将产生 108251 个任务实例。这意味着上述时间段总共有 108251 个小时，也意味着本次补数操作将从 gharchive 网站同步 108251 个文件到云对象存储上。

-## 任务编排
-
-在后续任务开发中，可以通过将本任务设置为依赖任务，实现工作流编排。

-# 使用Python任务实时获取GitHub的事件并导入Lakehouse表
-
-<https://api.github.com/events> 提供 API 服务，可以实时获取 5 分钟前的事件数据。通过 API 获得准实时数据，结合从 gharchive 网站通过文件方式同步的离线数据，可将数据的时效性从小时级别提升到分钟级别，进一步提升数据的新鲜度，更好地服务于对数据新鲜度有更高要求的应用。
-本示例也演示了如何通过云器 Lakehouse 的 [Python connect将数据以bulkload](use-python-sdk-upload-data.md) 方式将数据写入表中。
-
-## 创建目标表
-
-在 SQL 脚本任务节点中执行如下建表语句。
-
-```
-CREATE TABLE IF NOT EXISTS `github_timeline_realtime_events` (
-
-`id` STRING,
-
-`type` STRING,
-
-`repo_id` STRING,
-
-`repo_name` STRING,
-
-`minute` STRING,
-
-`second` STRING,
-
-`created_at` TIMESTAMP,
-
-`data` STRING COMMENT 'record data, json format',

-# 利用 External Catalog 访问 Snowflake Open Catalog 中的 Iceberg 表
-
-## **概述**
-
-Lakehouse 支持通过 Catalog Integration 功能连接第三方的 Iceberg REST API，实现与外部数据目录的无缝集成。本文档介绍如何连接和使用 Snowflake 的 Open Catalog 功能。
-
-**功能特性**：
-
-* **统一数据访问**：通过统一的接口访问 Snowflake Open Catalog 中的 Iceberg 表
-* **实时数据同步**：直接读取 Snowflake 中的最新数据，无需数据复制
-* **元数据映射**：自动映射 Snowflake 中的表结构和元数据信息
-* **OAuth 认证**：支持安全的 OAuth 2.0 认证机制
-
-## **环境准备**
-
-Snowflake Open Catalog 提供了两种类型的目录：
-
-**Internal Catalog**：
-
-* **功能特性**：Lakehouse 支持完整的读写操作
-* **数据管理**：支持表结构变更、数据插入、更新、删除等全生命周期操作
-
-**External Catalog**：
-
-* **功能特性**：Lakehouse 仅支持只读操作
-* **数据访问**：支持复杂查询、联表分析，但不支持数据修改操作
-
-在 Snowflake 中准备 Iceberg 表，并注册到 Snowflake Open Catalog 中，请参考 [Snowflake 官方文档](https://docs.snowflake.com/en/user-guide/tables-iceberg-open-catalog-sync)
-
-实现效果：在 Snowflake Open Catalog 中，注册了一张位于 Snowflake 引擎中的表：
-
-* Database 名称： ICEBERG\_TABLES\_DB\_FLATTEN
-* Schema 名称：ICEBERG\_SCHEMA
-* Iceberg 表名：czcustomer （要求小写。Snowflake 的建表 DDL 中，用双引号避免表名自动转成大写）
-
-> 注意：在 Snowflake 引擎中创建 Database 时，需加入 `CATALOG_SYNC_NAMESPACE_MODE` 和 `CATALOG_SYNC_NAMESPACE_FLATTEN_DELIMITER` 两个参数以调整 Catalog 层级。如下配置后，在 Snowflake Open Catalog 中，Database 与 Schema 将合并成一个层级："`ICEBERG_TABLES_DB_FLATTEN_ICEBERG_SCHEMA"`
->
-> ```
-> CREATE OR REPLACE DATABASE iceberg_tables_db_flatten
-> CATALOG_SYNC_NAMESPACE_MODE = 'FLATTEN'
-> CATALOG_SYNC_NAMESPACE_FLATTEN_DELIMITER = '_';
-> ```
-
-![](.topwrite/assets/20250901-112722.jpeg)
-
-## **配置步骤**
-
-### 步骤 1：创建 Catalog Connection
-
-使用以下 SQL 语句创建与 Snowflake Open Catalog 的连接：
-
-```
-CREATE CATALOG CONNECTION snow_opencatalog 
-    TYPE ICEBERG_REST 
-    URI='https://lhnrdre-derekmeng.snowflakecomputing.com/polaris/api/catalog'
-    ACCESS_REGION = 'ap-southeast-1' 
-    OAUTH_CLIENT_ID='d3r3cuhHitrI+fUpFtvXxxxxxxx'
-    OAUTH_CLIENT_SECRET='gY3ZWOGoSMM1tKK7QaqQYKpSdTcPY1ruVv7xxxxxxx'
-    OAUTH_SCOPE='PRINCIPAL_ROLE:ALL'
-    NAMESPACE='ICEBERG_TABLES_DB_FLATTEN_ICEBERG_SCHEMA'
-    WAREHOUSE='singdata'
-    WITH PROPERTIES (
-        'client.region'='ap-southeast-1',
-        'io-impl'='org.apache.iceberg.aws.s3.S3FileIO'
-    );
-```
-
-| 参数                    | 说明                                  | 示例                                                           |
-| --------------------- | ----------------------------------- | ------------------------------------------------------------ |
-| TYPE                  | 连接类型，固定为 `ICEBERG_REST`       | `ICEBERG_REST`                                               |
-| URI                   | Snowflake Polaris API 端点            | <https://account.snowflakecomputing.com/polaris/api/catalog> |
-| ACCESS_REGION         | 访问对象所在的区域                     | `ap-southeast-1`                                             |
-| OAUTH_CLIENT_ID       | OAuth 客户端 ID                       | 在 Snowflake Open Catalog 创建 Service connection 时获取     |
-| OAUTH_CLIENT_SECRET   | OAuth 客户端密钥                      | 在 Snowflake Open Catalog 创建 Service connection 时获取     |
-| OAUTH_SCOPE           | OAuth 授权范围                        | `PRINCIPAL_ROLE:ALL`                                         |
-| NAMESPACE             | Snowflake Open Catalog 中的第二个层级  | `ICEBERG_TABLES_DB_FLATTEN_ICEBERG_SCHEMA`                   |
-| WAREHOUSE             | Snowflake Open Catalog 的 Catalog 名称 | `singdata`                                                   |
-
-### 步骤 2：创建外部表
-
-创建外部表来映射 Snowflake Open Catalog 中的表：
-
-```SQL
--- 创建外表，映射 Snowflake Open Catalog 中的表（表名需一致）
-CREATE EXTERNAL TABLE IF NOT EXISTS `czcustomer`
-USING ICEBERG 
-CONNECTION snow_opencatalog;
-```
-
-> **注意**：外部表名必须与 Snowflake 中的表名完全一致。
-
-### 步骤 3：验证和查询
-
-验证表结构并查询数据：
-
-```SQL
--- 查看表结构
-DESC EXTENDED `czcustomer`;
-
--- 查询数据
-SELECT * FROM `czcustomer` LIMIT 10;
-```
-
-![](.topwrite/assets/opencatalog_3.jpeg)
-
-## 使用限制
-
-* 连接基于 S3 的 Snowflake 托管的 Iceberg 表时，不支持写入和更新操作
-* 外部表名必须与 Snowflake 中的源表名完全匹配
-* 暂时仅支持小写表名
-* 不支持表名转换
-* 在目标 Catalog 服务侧，需要开启 Credential Vending 配置

-```
---加载数据
-set copy.csv.with.header=false;
-set copy.csv.skip.header=true;
-copy central_park_weather_observations from '/opt/data/central_park_weather.csv' ;
-```
-
-请下载 [central\_park\_weather.csv](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/sample_data/central_park_weather.csv)，点击“Download raw file”下载到本地，并修改上述代码中的目录 (/opt/data/) 为你所下载的目录。
-然后验证数据是否已经加载成功：
-
-```
-select count(1) from central_park_weather_observations;
-```
-
-## 探查数据
-
-```
-SELECT * FROM central_park_weather_observations LIMIT 10;
-```
-
-## 分析数据
-
-```
-SELECT date, sum(precipitation) FROM central_park_weather_observations
-GROUP BY date
-ORDER BY date;
-```
-
-## 清理
-
-```
-DROP TABLE IF EXISTS central_park_weather_observations;

-# 刷新物化视图
-
-## 功能描述
-
-在数据库中，物化视图是一种特殊的视图，它将查询结果以表的形式存储在数据库中。当物化视图所依赖的表数据发生变化（如插入、覆写、更新、删除等操作）时，物化视图会自动失效，无法用于查询和改写。为了确保物化视图的数据保持最新，需要手动刷新物化视图。
-
-有关更多详细信息，请参阅[物化视图](<MATERIALIZEDVIEW.md>)。
-
-## 语法
-
-```SQL
-REFRESH MATERIALIZED VIEW mv_name;
-```
-
-## 参数说明
-
-- **mv_name**：指定要刷新的物化视图名称。
-
-## 使用示例
-
-1. 假设我们有一个物化视图 my_mv，它是基于员工表（employees）和部门表（departments）的关联查询结果创建的。现在我们需要刷新 my_mv，以确保它包含最新的员工和部门信息。可以使用以下 SQL 语句：
-
-   ```SQL
-   REFRESH MATERIALIZED VIEW my_mv;
-   ```
-
-2. 另一个例子，如果我们有一个物化视图 sales_summary，它根据销售数据表（sales_data）生成销售摘要。当销售数据表发生更改时，我们需要刷新 sales_summary 以反映最新的销售情况。可以使用以下 SQL 语句：
-
-   ```SQL
-   REFRESH MATERIALIZED VIEW sales_summary;
-   ```
-
-## 注意事项
-
-1. 在执行刷新物化视图操作时，确保物化视图所依赖的表数据已经更新。
-2. 刷新物化视图可能会消耗较多的系统资源和时间，尤其是在处理大量数据时。因此，建议在系统负载较低时执行此操作，以免影响其他数据库操作。
-3. 根据物化视图的复杂程度和依赖关系，刷新操作可能会触发重新计算物化视图的查询结果。在某些情况下，可以考虑使用增量刷新（如支持的数据库系统），以提高刷新效率。

-## 新功能特性
-
-### 【预览】支持创建倒排索引加速检索分析
-
-本次发布新增倒排索引支持。倒排索引对文本进行分词处理，同时保存分词与记录之间映射关系。当用户根据关键词进行文本检索时，查询引擎将通过索引数据快速找到匹配的数据记录，显著加速文本检索性能。
-
-本次发布支持对字符串类型字段创建倒排索引，并提供了一组内建函数用于表达文本匹配条件及规则。
-
-更多信息，请查看[倒排索引](inverted-index.md)文档。
-
-### 数据湖存储Volume新增内部Volume对象类型
-
-在外部Volume基础上，新增表Volume和用户Volume两种内部Volume类型。表Volume和用户Volume由系统预定义默认创建，内部Volume的数据保存在Lakehouse托管存储区域，无需与外部存储服务打通即可快速管理和使用非结构化数据。内部Volume能够简化UDF资源文件管理、数据导入/导出文件临时存储以及开发测试等场景的文件数据管理和使用。
-
-更多信息，请查看[Volume](datalake_volume.md)文档。
-
-### 【预览】External Function 支持UDAF和UDTF
-
-External Function先前已经提供了对UDF（即：scalar UDF）的支持，本次升级扩展支持UDFA和UDTF自定义函数。您可以使用Hive UDF API开发UDAF以及UDTF。
-
-文档更新，增加了UDF、UDAF、UDTF的开发样例说明。
-
-更多信息，请查看[Java UDF开发指南](ExternalFunctionDevGuideJava.md)文档。
-
-### 外部表：支持DELTA LAKE外部表
-
-新增外部表对象类型，通过外部表无需将数据导入，可直接访问外部存储中的数据。本次发布支持创建和使用DELTA LAKE格式的外部表。创建外部表时，支持使用CONNECTION对象定义外部表的服务连接信息。
-
-更多信息，请查看[外部表](external-table-guide.md)文档。
-
-### 【 预览】PIPE管道任务支持Kafka数据实时导入
-
-新增PIPE对象类型，通过PIPE管道可以创建从外部流式数据源持续导入数据到目标表的实时任务。无需第三方ETL工具或引擎，PIPE任务由SQL引擎直接实现流式数据源的读取和写入，减少了不必要的中间暂存、格式转换的计算开销，能够极大提升实时导入环节，提高导入吞吐并降低导入成本。
-
-更多信息，请查看[PIPE管道](pipe-summary.md)文档。
-
-## 数据湖更新
-
-### 服务连接对象支持GCS对象存储
-
-通过STORAGE CONNECTION可以管理对象存储服务的连接及身份认证信息，当前支持阿里云OSS、腾讯云COS基础上，增加对谷歌云GCS对象存储服务的支持。使用STORAGE CONNECTION可实现存储服务连接的权限控制，不同任务和用户可复用已定义的连接对象。
-
-更多信息，请查看[CONNECTION](CREATECONNECTION.md)文档。
-
-### External Schema增加访问HMS管理的GCS数据
-
-External Schema通过映射外部元数据服务下的Schema（或者两层结构下的database），实现对外部Schema下数据对象的外表访问。本次升级，External Schema增加对HMS存储在谷歌云GCS数据的访问能力。
-
-更多信息，请查看[外部Schema](EXTERNALSCHMEA.md)文档。
-
-## 实时增量计算
-
-### 动态表：查看动态表刷新历史
-
-新增SHOW DYNAMIC TABLE REFRESH HISTORY命令，支持查看动态表刷新历史。刷新历史中可观察到每次刷新作业的执行状态、刷新作业运行时长、增量或全量刷新类型、当次刷新任务处理的记录数量（包括写入、删除类型）等信息。通过刷新历史可以实现动态表刷新运行（特别是周期性运行）的监控，根据指标情况调整调度周期或者资源大小以满足业务SLA要求。
-
-文档更新：增加[动态表使用最佳实践](<dynamic_table_summary.md>)介绍。
-
-更多信息，请查看[动态表](dynamictable.md)文档。
-
-### 【预览】动态表：支持对使用自定义函数的动态表进行增量处理
-
-动态表的定义，支持使用通过External Function创建的自定义函数（包括UDF、UDAF、UDTF）。在使用了自定义函数定义的动态表执行刷新时，系统自动将进行增量处理优化，进一步扩展了动态表增量处理的适用范围。
-
-预览期间非默认打开，该功能需要通过特定参数启用。
-
-更多信息，请查看[动态表中使用UDF](using-udf-in-dynamic-table.md)文档。
-
-## Information Schema更新
-
-### Information Schema新增Volume和Connection对象视图
-
-新增数据湖存储*VOLUMES视图*、*CONNECTIONS视图*，您可以通过查询INFORMATION\_SCHEMA下的对应视图获取数据湖存储Volume和外部服务连接Connection对象信息。
-
-更多信息，请查看[INFORMATION\_SCHEMA](instance-informaiton-schema.md)文档。
-
-## SQL 能力更新
-
-### 支持使用同义词SYNONYM作为别名访问已有对象
-
-通过创建SYNONYM同义词可以对已有数据对象的位置及名称进行引用和包装，可以简化数据对象的访问或者提升数据对象访问的安全性。
-
-更多信息，请查看[同义词](synonym.md)文档。
-
-### 支持TIMESTAMP\_NTZ类型
-
-时间数据类型在TIMESTAMP\_LTZ类型基础上，增加TIMESTAMP\_NTZ类型。TIMESTAMP\_NTZ类型即timestamp without time zone，用于存储不包含时区信息的日期和时间值，不考虑时区的变化。相较于其他带有时区的时间戳类型（TIMESTAMP\_LTZ），TIMESTAMP\_NTZ无需进行时区转换，能够极大简化在多时区环境或跨系统传输数据场景下的时间戳类型数据的处理逻辑。
-
-更多信息，请查看[TIMESTAMP\_NTZ 类型](data-types-timestamp-ntz.md)文档。
-
-### 【预览】使用IDENTITY设置字段自增属性
-
-在创建表时，支持对使用IDENTITY列属性指定自增长列。
-
-更多信息，请查看[IDENTITY自增列](IDENTITY-Column.md)文档。
-
-### 内建函数
-
-本次发布新增以下内建函数：

-自动导入服务在支持Kafka数据自动实时导入基础上，增加了对象存储文件数据的实时导入能力。自动导入服务可订阅对象存储的文件变化事件，根据事件自动触发导入任务，实现了对对象存储中快速变化数据文件的自动增量导入能力。
-
-### COPY INTO \<Location>支持导出表数据为JSON格式
-
-COPY INTO \<location>命令扩展了导出格式，通过FILE\_FORMAT = (TYPE = JSON) 参数可导出表数据为JSON格式文件。
-
-## 联邦查询更新
-
-### 扩展Catalog Connection连接类型，支持外部Catalog服务连接定义
-
-增加Catalog Connection对象类型，支持创建与外部Catalog服务（如Hive Metastore）的连接定义，在创建External Catalog/External Schema/External Table时可引用Catalog Connection简化定义、提高连接信息的安全性。
-
-### 外表查询增加METADATA缓存能力
-
-通过 External Table/External Schema/External Catalog 查询外部表时，云器 Lakehouse 增加了远程元数据的本地缓存能力，以加速外部数据查询。
-
-## 虚拟计算集群更新
-
-### 【预览】Preload Cache支持仅对分区表的最近分区进行动态Cache
-
-支持对分区表近期分区进行主动 Cache 的配置，系统自动根据分区的变化淘汰过期分区的 Cache 数据、加载新分区数据。通过该功能，能够有效地利用分析型集群的本地 Cache 对近期热数据进行缓存加速，适合存量历史数据较多、查询分析主要关注近期数据的业务场景。
-
-## 增量计算更新
-
-### 动态表DDL定义支持用户指定自动刷新作业运行的虚拟计算集群
-
-在CREATE DYNAMIC TABLE的DDL定义中，支持使用REFRESH INTERVAL \[interval\_time] VCLUSTER \<virtual\_cluster\_name>语法设置自动刷新作业使用的集群名称。
-
-## SQL 能力更新
-
-### 支持SHOW PARTITIONS语法查看分区表分区信息
-
-Lakehouse 采用隐式分区方式定义和使用分区表。为了兼容Hive的分区管理的使用习惯、增强基于分区的管理和优化能力，本期提供了SHOW PARTITIONS语法查看分区表分区信息。同时可使用SHOW PARTITIONS EXTENDED语法查看分区扩展信息，包括：分区值、分区记录数、分区数据大小、分区创建时间、分区最后修改时间。通过 SHOW PARTITIONS EXTENDED，用户可以了解分区的数量、大小及修改信息。Lakehouse平台也可以借助元数据中的分区信息在历史数据归档、Preload Cache主动缓存等场景进行细粒度的管理和优化。
-
-### SHOW TABLES命令的数据对象类型增加了外表、动态表扩展
-
-SHOW TABLES命令的返回信息扩展了is\_external、is\_dynamic字段，用于区分是否为外表或动态表。
-
-### 兼容性扩展：新增MAX\_PT函数，支持查看最新分区表最大分区
-
-使用max\_pt可返回分区表最大的一级分区的值，对于存量任务使用该函数的作业增强了语法兼容性。
-
-### 内建函数
-
-本次发布新增以下内建函数：
-
-| **函数名称**                   | **说明**                                        |
-| -------------------------- | --------------------------------------------- |
-| CHARACTER\_LENGTH          | 返回字符串中字符的数量                                   |
-| CHAR\_LENGTH               | 等效于CHARACTER\_LENGTH，用于返回字符串中字符的数量。           |

-## 新功能特性
-
-### 【预览】支持Clone功能
-
-Lakehouse CREATE CLONE 功能允许你创建现有对象的副本,而无需实际复制数据。这种零副本克隆(Zero Copy Cloning)使用元数据引用原始数据,从而实现快速创建克隆,并且不会消耗额外的存储空间。支持普通表和动态表克隆
-
-## 联邦查询更新
-
-### 【预览】外部表新增支持读取Hudi格式
-
-本次发布支持创建和使用Hudi格式的外部表。创建外部表时，支持使用CONNECTION对象定义外部表的服务连接信息。
-
-### 【预览】Hive联邦支持写入
-
-**支持写入**：Hive联邦功能现已支持写入操作，使用户能够将数据写入不同的数据存储系统。通过Hive联邦，用户可以使用统一的SQL接口访问和写入多个数据源，简化了数据管理和操作。
-
-### External Schema支持使用Connection
-
-之前，External Schema的连接参数需要填写在PROPERTIES中。增强后，这些参数可以在Connection中填写。通过使用Connection，用户无需将身份认证信息以明文形式暴露，从而确保数据的安全性。Connection创建一次后，下游可以多个对象使用，提高了配置的复用性和管理的便捷性。
-
-## 导入导出更新
-
-### COPY INTO \<location>功能增强
-
-* 支持PURGE=TRUE参数:当设置PURGE=TRUE时，在加载过程中删除已成功加载的文件。
-* 支持`OVERWRITE`参数：使用`OVERWRITE`参数时，现有表数据将被清空，然后导入新的数据。`OVERWRITE`具有原子性，只有在导入成功后才会清空表数据并写入新数据。
-
-### Pipe功能增强
-
-* **新增模式**：即使在没有对象存储消息服务通知的情况下，Pipe也能检测到新增文件并进行同步。
-* **导入历史记录**：Pipe读取对象存储的功能还支持`load_history`函数，用于记录成功导入的文件。
-* **Pipe过滤**：新增了Pipe过滤功能，用户可以通过`query tag`来过滤Pipe作业历史。
-
-## 虚拟计算集群
-
-* **GP型动态扩容能力**：支持在任务出现资源等待和排队情况时进行动态扩容，解决了无法纵向扩容（增加单集群实例CPU和内存数）的限制。这有助于应对GP VC上负载波动大的情况，避免按照峰值购买VC资源的不经济性，同时满足负载波峰的需求。
-* **VC SIZE设置**：支持设置CRU数值大小。CRU是计算资源的计量单位，1 CRU相当于云厂商云服务器资源8核运行1小时所提供的算力。
-
-## 增量计算更新
-
-### TABLE\_CHANGES函数增强
-
-* 默认行为：TABLE\_CHANGES函数会返回在指定偏移量之后和当前时间之前提交的事务所造成的变化，但不会返回具体的操作明细。例如，如果在两个点位之间先发生了插入（insert），然后发生了删除（delete），默认情况下返回结果为空。
-* 增强功能：通过增加`map('TABLE_STREAM_MODE', 'ORIGINAL')`参数，TABLE\_CHANGES函数会返回两个点位之间的所有变化明细。例如，上述案例中的插入和删除操作都会被返回。
-
-## SQL查询优化
-
-### 小文件优化
-
-* **自动合并小文件**：在执行写入操作（如INSERT、UPDATE、DELETE、COPY语句）前，通过设置set cz.sql.compaction.after.commit=true;，可以自动触发小文件合并。这有助于提高后续查询的效率，因为可以避免读取大量小文件。请注意，启用此设置后，INSERT、UPDATE、DELETE、COPY语句的执行时间可能会增加。
-
-### Preload Cache
-
-* AP型计算集群（ANALYTICS PURPOSE VIRTUAL CLUSTER）支持查看缓存状态
-
-## SQL 能力更新
-
-### 创建表时支持指定默认值和生成列
-
-* 在本SQL引擎中，创建内部表时，您现在可以为列指定默认值（defalult value）或定义生成列(generated column)，以自动化数据填充和处理。这使得数据管理更加高效，特别是在处理分区表时。目前不支持实时写入接口写入，如果实时接口没指定该值则会为null不会自动填充该值。
-
-### 支持向量索引
-
-采用 HNSW（Hierarchical Navigable Small World）算法构建向量索引。用来加速向量检索。
-
-### 数据类型
-
-Array类型:可以使用常量格式如 `[1, 2, 3]` 来定义数组,当字符为上述格式时，会被识别为数组类型。
-
-Vector类型：Lakehouse 提供了 VECTOR 类型来存储这些转化后的向量，构建索引可以提高向量搜索性能
-
-### 函数支持
-
-| 函数名称              | 功能                                |
-| ----------------- | --------------------------------- |
-| median            | 根据组的值计算出的中值                       |
-| group\_concat     | 将组中的值连接成一个字符串。                    |
-| multiif           | 用于在查询中更紧凑地编写 CASE 运算符.            |
-| ceiling           | 返回大于或等于指定数的最小整数。等同于ceil           |
-| log               | 计算指定数的对数。                         |
-| current\_timezone | 返回当前时区。                           |
-| power             | 计算指定数的幂。                          |
-| if                | 支持两个参数，如果不写第三个参数默认是NULL           |
-| nvl2              | 如果第一个参数不为NULL，则返回第二个参数，否则返回第三个参数。 |
-
-## 行为变更
-
-### 数据类型
-
-varchar数据类型变化:varchar长度变更由65535变为1048576
-
-### SDK接口
-
-在 JDBC 2.0.0 之后的版本中，本地 COPY 命令已被弃用。我们建议您使用 PUT 方法将数据上传到 volume 中，然后使用服务器端的 COPY 命令进行导入。

-* 运维中心：在实例状态方面，新增通过Tooltip显示状态的具体子状态（例如“空跑置成功”等），以便快速查看细化的状态分类。
-* 运维中心：在任务实例详情页中，新增展示任务的调度定时信息。
-* 运维中心：合并周期任务列表的“最后一次运行时间”与“状态”显示列，提升阅读的视觉效率。
-* 运维中心：在多表实时同步运维中，在执行日志中显示更多报错信息，以便排查和定位问题。
-* 监控告警：对于因上游实例暂停而被阻塞或因超时被终止的实例，不触发实例运行失败的告警。
-* 监控告警：在周期任务实例的监控告警信息中，新增显示实例的计划定时时间，以便识别报警对应的任务。
-* 作业历史：优化用户在作业历史详情页的使用体验，包括优化集群CRU展示页面、处理失效URL跳转问题。
-
-## 问题修复
-
-* 数据同步：解决从 MySQL 实时同步过来的 tinyint(1) 数值与源表不一致的问题。
-* 数据同步：解决多表实时任务按点位启动后，在特殊情况下会触发重建底表的问题，调整为不进行重建。
-* 集群管理：解决作业存在排队情况时，查看 VC 页面详情无法显示的问题。
-* 监控告警：解决任务运行延迟告警疑似误触发的问题。
-
-## 已知局限
-
-* 本次版本更新无已知的新增的重大局限。

-# 2025年03月03日 — 1.0 Lakehouse Platform 产品更新发布说明
-
-本次发布，我们引入了一系列新功能、增强特性以及修复项。这些更新将分阶段逐步推送至以下区域，预计在发布日起一周至两周内完成。具体时间依据您所在的区域而定。
-
-* 阿里云上海区
-* 腾讯云上海区
-* 腾讯云北京区
-* 腾讯云广州区
-* 亚马逊北京区
-* 国际站-阿里云-新加坡区
-* 国际站-AWS-新加坡区
-
-## 新功能特性
-
-### 联邦查询更新【预览发布】
-
-* **架构扩展**：云器Lakehouse支持使用External Schema在Catalog级别映射和镜像外部数据源支持查询 Hive（之前只支持 Hive 对象存储架构，本期支持 Hive HDFS 架构）。参考[EXTERNAL SCHEMA](EXTERNALSCHMEA.md)
-* **增强Delta Lake格式读取**：创建外部表Delta Lake格式自动Schema推断——创建外部表时无需手动声明字段信息，系统自动解析元数据。参考[Delta Lake 外部表](delta-lake.md)
-
-## 导入导出更新
-
-### COPY命令增强
-
-支持双字符CSV分隔符（如 `||`），突破原有单字符限制，提升复杂数据兼容性。参考[COPY INTO导入](copy-into-table.md)
-
-### Pipe功能增强
-
-1. 支持[Kafka Table Stream](pipe-kafka-table-stream.md)直连导入，通过 Table Stream 您可以实现 Exactly Once，同时支持将连接信息存储在 Connection 中
-
-2. [Pipe SQL命令优化](pipe-syntax.md)
-
-   * 支持通过`SHOW CREATE PIPE pipe_name`获取Pipe的DDL语句
-   * Pipe DESC 结果输出优化。DESC PIPE pipe_name 显示结果字段，Pipe 任务的输入对象名称和输出对象名称，增加 Kafka 点位消费信息
-   * 支持Alter命令修改Pipe导入参数如修改计算集群
-
-3. Pipe导入对象存储数据。支持过滤`.`开头和 `_temporary` 开头的文件或者目录文件。参数`IGNORE_TMP_FILE=FALSE|TRUE`。例如：
-
-   ```
-   s3://my_bucket/a/b/.SUCCESS
-   oss://my_bucket/a/b/_temporary
-   oss://my_bucket/a/b/_temporary_123/
-   ```
-
-## 计算集群
-
-**精细化资源控制**
-
-新增[GP型计算集群单作业资源占比配置](alter-vcluster.md)，控制单作业最大资源占比 10%。避免大查询引发的资源抢占，提升集群稳定性：
-
-```
-ALTER VCLUSTER sample_vc SET QUERY_RESOURCE_LIMIT_RATIO='0.1'; 
-```
-
-## SQL语法
-
-1. 支持创建[SQL FUNCTION](create-sql-function.md)。通过这一功能，用户能够利用SQL DDL（数据定义语言）语句来定义自定义的SQL函数，从而增强数据处理和分析的灵活性。
-2. Lakehouse 正式推出[列级安全（Column-level Security）功能](dynamic-mask.md)，支持通过动态脱敏（Dynamic Data Masking）实现对敏感数据的细粒度控制。此功能允许管理员根据用户角色或属性，动态隐藏、部分显示或替换列中的敏感信息（如身份证号、信用卡号等），从而有效保护数据隐私。用户可以通过以下 SQL 语句实现动态脱敏：
-
-```SQL
-ALTER TABLE <table_name> MODIFY COLUMN <column_name> SET MASKING POLICY <policy_name>;
-```
-
-通过定义脱敏策略并将其应用于表的列，在查询运行时，屏蔽策略将应用于该列出现的每个位置，根据屏蔽策略条件、SQL 执行上下文角色或者用户来进行脱敏。
-
-3. Lakehouse 数据存储优化功能。通过 [OPTIMIZE 命令](small_file_optimization.md)的高级参数，用户可以进行小文件合并
-4. DML增强：`UPDATE` 支持 `ORDER BY ... LIMIT` 语法
-5. 【预览发布】[多方言兼容](sql-parmaters.md)：通过SQLGlot集成支持PostgreSQL/MySQL/Hive/Presto等方言的部分语法
-
-## UDF功能
-
-新增 `cz.sql.remote.udf.lookup.policy` 配置参数,支持动态切换 UDF 与内置函数的解析优先级
-
-```SQL
--- 策略1：优先调用内置函数（兼容传统OLAP系统行为）
-SET cz.sql.remote.udf.lookup.policy = builtin_first;
-
--- 策略2：优先调用UDF（适配MC/Spark作业场景）
-SET cz.sql.remote.udf.lookup.policy = udf_first;
-
--- 默认策略：强制要求UDF带Schema前缀（保持历史兼容性）
-SET cz.sql.remote.udf.lookup.policy = schema_only; 
-```
-
-## 权限管理【预览发布】
-
-[新增Instance级别角色与跨空间授权能力](CREATEROLE.md):支持在实例（Instance）粒度创建角色并授予全局权限，实现跨空间（Workspace）的统一权限管控，满足多团队协作场景下的精细化访问控制需求。
-

-## 系统行为变更
-
-* 新建工作空间时，默认新建一个名称为‘DEFAULT\_INTEGRATION’的同步型集群，便于处理该工作空间的数据集成类任务。该集群默认关闭，不会在新建工作空间时产生计算资源消耗和费用。存量工作空间不变更。

-# 重新定义ELT：通过云器Lakehouse实现ELT新方式
-
-## 问题与挑战
-
-在很多数据项目中，特别是与ML、AI关系比较紧密的数据项目中，往往需要通过Python、SQL混合的方式进行开发实现，比如通过Jupyter Notebook进行Python代码的开发，用DBeaver、VS Code等数据管理和开发工具进行SQL代码的开发。在这种方案中，经常容易发生版本管理缺失、缺少统一的调度服务等问题，从而使开发和运维变得复杂且困难。
-
-随着现代化数据栈的发展，Metabase、MindsDB等新一代BI、AI分析产品也得到飞速发展。数据平台如何紧密融入现代化数据栈，提供完整的解决方案，也变得至关重要。
-
-对于日趋增多的半结构化数据以及向量数据（如CSV、JSON），如果依赖客户端解析会严重影响整体处理速度，这就要求数据平台能够同时高性能地处理表格中的结构化数据以及JSON数据、向量数据。比如GH Archive提供的GitHub每小时的事件归档数据集，就是以JSON格式提供的。
-
-在数据清洗和转换的数据工程工作中，往往需要开发很多中间表才能得到最终的目标表。如何提高这一环节的效率，也成为提升数据工程师生产力的一个重要课题。
-
-## 通过云器Lakehouse实现ELT的新方式
-
-今天笔者尝试使用云器Lakehouse，从以下三个方面寻找以上问题的新解法。
-
-![](.topwrite/assets/image_1734348544459.png)
-
-### 统一数据任务开发和调度
-
-通过云器Lakehouse简化数据任务开发和运维环境，实现统一的任务版本管理：
-
-* [Python任务开发](Python_Task.md)：从Jupyter Notebook开发到云器Lakehouse Studio的Python任务开发。
-
-* [SQL任务开发](taskdevelop.md)：从DBV SQL任务开发到云器Lakehouse Studio的SQL任务开发。
-
-* [ML/AI任务开发](jdbc_task.md)：从MindsDB Web IDE到云器Lakehouse Studio的JDBC任务开发。
-
-* [任务调度和运维](task-instance-maintenance.md)：从Airflow到云器Lakehouse Studio任务调度和运维。
-
-  ![](.topwrite/assets/image_1734348698701.png =460)
-
-### [多数据类型支持](data-type.md)
-
-云器Lakehouse支持以下数据类型的高效存储和访问：
-
-* Table里常见的基本数据类型
-
-* Table里常见的复杂数据类型
-
-* JSON
-
-* Vector
-
-* 文本倒排索引
-
-  ![](.topwrite/assets/image_1734348746004.png =380)
-

-
-## 应用案例：GHArchive数据ELT流程实现
-
-![](.topwrite/assets/image_1734348838607.png)
-
-### 数据源介绍：[GHArchive](http://www.gharchive.org/)
-
-全球范围内的开源开发者正在从事数以百万计的项目，涵盖诸如编写代码和文档、修复错误以及提交等工作。[GH Archive](http://www.gharchive.org/) 这一项目会对公共GitHub的事件数据予以记录，该项目提供了自2011年2月12日起始，长达13年多的GitHub事件数据存档，并使数据更易于访问，为进一步分析创造便利条件。
-
-GitHub有15种以上事件类型，例如新提交（Push）、分叉仓库（Fork）、新建Issue、评论以及为项目添加成员等。这些事件会汇总到每小时的归档文件里，用任何HTTP客户端都能访问这些归档文件，每个归档文件里都以JSON编码GitHub API报告的事件。用户可以下载原始数据自行处理，例如编写自定义聚合脚本、将其导入数据库等。
-
-GitHub 的事件数据示例如下：
-
-```
-{"id":"44809399421","type":"CreateEvent","actor":{"id":81469924,"login":"temperature48","display_login":"temperature48","gravatar_id":"","url":"https://api.github.com/users/temperature48","avatar_url":"https://avatars.githubusercontent.com/u/81469924?"},"repo":{"id":903968841,"name":"temperature48/SmashVat","url":"https://api.github.com/repos/temperature48/SmashVat"},"payload":{"ref":null,"ref_type":"repository","master_branch":"master","description":null,"pusher_type":"user"},"public":true,"created_at":"2024-12-16T02:00:00Z"}
-```
-
-^
-
-### 开发任务：数据抽取（**E**xtract）
-
-接下来我们通过云器Lakehouse Studio开发一个Python任务，将数据从GH Archive网站抽取到数据湖存储（本方案采用阿里云OSS）中。
-
-![](.topwrite/assets/image_1734348912514.png)
-
-^
-
-```py
-import os,io
-import subprocess
-from datetime import datetime, timedelta
-import oss2
-
-# 阿里云OSS配置
-ACCESS_KEY_ID = '${ak}'
-ACCESS_KEY_SECRET = '${sk}'
-BUCKET_NAME = 'OSS上的Bucket名字'
-ENDPOINT = '阿里云OSS的Endpoint'
-ROOT_PATH = 'ghachive，替换为Bucket下的真实的根目录'
-
-# 获取当前东八区时间
-# beijing_time = datetime.now() 
-beijing_time = datetime.strptime('${datetime}', "%Y-%m-%d %H:%M:%S")
-
-# 获取文件时间，北京时间偏差9个小时即可(时间8小时，gharchive网站产出数据文件晚1个小时，8+1)
-ny_time = beijing_time - timedelta(hours=9)
-
-# 格式化时间
-year = ny_time.strftime('%Y')
-month = ny_time.strftime('%m')
-day = ny_time.strftime('%d')
-hour = ny_time.strftime('%H')
-
-# 打印转换后的时间
-print(f"Converted to data file Time and -9 hour: {year}-{month}-{day} {hour}:00:00")
-
-# 判断小时是否是'0x'格式，是的话去掉前导0
-if hour.startswith('0') and len(hour) > 1:
-    # 去掉前导的'0'
-    hour = hour[1:]
-
-try:
-    # 构建wget命令
-    url = f"https://data.gharchive.org/{year}-{month}-{day}-{hour}.json.gz"
-    cmd = ["wget", "-qO-", url]
-    print(f"wget cmd: {cmd}")
-
-    # 执行wget命令并捕获输出
-    wget_output = subprocess.check_output(cmd)
-    print(f"Wget file done...")
-
-    # 将输出转换为内存中的文件对象
-    file_obj = io.BytesIO(wget_output)
-except Exception as e:
-    print(f"An error occurred: {e}")
-    file_obj = None
-    raise
-
-if file_obj:
-    try:
-        # 初始化阿里云OSS
-        auth = oss2.Auth(ACCESS_KEY_ID, ACCESS_KEY_SECRET)
-        bucket = oss2.Bucket(auth, ENDPOINT, BUCKET_NAME)
-
-        # 上传文件到OSS
-        oss_path = f"{ROOT_PATH}/{year}/{month}/{day}/{year}-{month}-{day}-{hour}.json.gz"
-        print(f"osspath: {oss_path}")
-        bucket.put_object(oss_path, file_obj)
-        print(f"Put file to oss done...")
-    except Exception as e:
-        print(f"An error occurred: {e}")
-    finally:
-        # 关闭内存中的文件对象
-        file_obj.close()
-```
-

-
-### 开发任务：数据加载任务（**L**oad）
-
-云器Lakehouse Studio支持通过离线同步任务，将数据从数据湖加载到Lakehouse的Table里，以优化的格式进行存储，并且便于细粒度的权限管理。
-
-![](.topwrite/assets/image_1734348942887.png)
-
-^
-
-### 开发任务：数据清洗与转换（**T**ransform）
-
-云器Lakehouse动态表（Dynamic Table）是一种支持仅处理增量变化数据的表，具备增量刷新优化能力。与传统的ETL任务相比，动态表无需进行全量数据计算，也无需指定增量逻辑（如按分区对齐或使用max(system/event_time)）。用户只需直接声明定义业务逻辑，动态表即可自动进行增量计算优化。
-
-本文使用动态表进行数据清洗和转化。
-
-![](.topwrite/assets/image_1734348956194.png)
-
-^
-
-#### 即席数据分析（Ad Hoc）
-
-云器Lakehouse 内置了便捷的SQL查询界面，可以自由编写SQL代码、使用变量、选择集群，进行灵活的即席数据分析（Ad Hoc）。也便于进行调试运行。
-
-![](.topwrite/assets/image_1734348969154.png)
-
-^
-
-#### 开发任务：AI/ML增强分析
-
-基于Lakehouse Studio提供的JDBC任务节点，可以便捷地连接到MindsDB，进行增强的数据分析。
-
-![](.topwrite/assets/image_1734348988810.png)
-
-^
-
-### 增量同步任务调度
-
-对刚才开发好的ELT任务进行调度定时和依赖关系配置，确保任务按小时周期运行，提交并发布任务，这样就可以从GHArchive按小时同步到一小时前的GitHub事件数据，并进行清洗和转换。
-
-![](.topwrite/assets/image_1734349005883.png)
-
-^
-
-### 补全量数据
-
-对于补数据任务，在云器Lakehouse Studio里，可以与增量任务完全复用，只需要按照全量数据的开始和结束日期配置并执行补数任务即可，来回刷写历史存量数据。
-
-以GHArchive的数据为例，其网站（http://www.gharchive.org/）的数据开始日期为2011年2月12日，则按下图配置补数任务并运行即可实现全量数据的同步，补全量任务可以与增量数据同步任务同时进行，也无需开发新的全量同步任务。
-
-![](.topwrite/assets/image_1734349021555.png)
-
-^
-^
-
-### 任务运维
-
-云器Lakehouse Studio也提供了完善的运维操作界面，比如展示任务的上下游DAG关系，运行状态，进行重跑等运维操作。

-# 使用流程: External Function
-
-## 文档目标：
-
-通过本篇使用流程，您可以实现：
-
-* 调用JAVA NLP 的离线模型（详见[网址](https://github.com/Ruthwik/Sentiment-Analysis)），解析云器Lakehouse 表中字符串的情绪
-* 调用阿里云视觉智能开放平台服务（详见[网址](https://help.aliyun.com/document_detail/203520.htm?spm=a2c4g.601126.0.0.39de5a4eqBtLaC)），解析云器Lakehouse 表中 url 指向的图片数据
-
-（本篇最佳实践使用的环境为基于阿里云的云器 Lakehouse。）
-
-## 操作步骤:
-
-### Step0：准备工作（授权操作）
-
-本步骤目标是：允许云器 Lakehouse 集群访问客户侧的阿里云上的函数计算 FC、对象存储服务 (OSS)。为了完成这个目标，需要创建一个角色，让云器 Lakehouse 扮演这个角色去访问阿里云上的函数计算 FC 和 OSS 服务。
-
-#### 1. 阿里云控制台：在阿里云控制台**访问控制**(RAM)中创建权限策略 (如：CzUdfOssAccess )：
-
-* 进入阿里云 RAM 控制台
-* 左侧导航栏 **权限管理** -> **权限控制**，在**权限控制**界面选择**创建权限策略**
-* 在**创建权限策略**页面选择**脚本编辑**页签（将下面 [] 中的 bucket 名称替换）。
-
-```JSON
-{
-    "Version": "1",
-    "Statement": [
-        {
-            "Effect": "Allow",
-            "Action": [
-                "oss:GetObject",
-                "oss:PutObject",
-                "oss:DeleteObject"
-            ],
-            "Resource": [
-                "acs:oss:*:*: [bucket_name]/*",
-                "acs:oss:*:*:[bucket_name]/*"
-            ]
-        }
-    ]
-}
-```
-
-^
-
-#### 2. 阿里云控制台：在阿里云 RAM 中创建角色（如：CzUDFRole）：
-
-* 在RAM 控制台左侧导航栏 **身份管理** -> **角色**，点击**创建角色**
-* 在**创建角色**页面中，选择类型为**阿里云账号**，在配置角色中填写自定义**角色名称**（如 CzUDFRole），在**选择信任的云账号**中选择**其他云账号**，并写入：1384322691904283（云器 Lakehouse 上海的云主账号），点击**完成**。
-* 编辑**AliyunFCFullAccess 权限策略**，添加下面 "acs:Service": "fc.aliyuncs.com" 部分。
-
-```Properties
-{
-    "Version": "1",
-    "Statement": [
-        {
-            "Action": "fc:*",
-            "Resource": "*",
-            "Effect": "Allow"
-        },
-        {
-            "Action": "ram:PassRole",
-            "Resource": "*",
-            "Effect": "Allow",
-            "Condition": {
-                "StringEquals": {
-                    "acs:Service": "fc.aliyuncs.com"
-                }
-            }
-        }
-    ]
-}
-```
-
-* 创建完成之后，点击**为角色授权**:
-* 在**系统策略**中，将**AliyunFCFullAccess**策略授权给该角色 CzUDFRole。
-* 在**自定义策略**中，将刚创建的策略（**CzUdfOssAccess**）授权给该角色。
-
-#### 3. 在角色 CzUDFRole 详情页中，获取该角色的 RoleARN 信息：
-
-* 修改 CzUDFRole 的**信任策略**：
-
-```Python
-{
-  "Statement": [
-    {
-      "Action": "sts:AssumeRole",
-      "Effect": "Allow",
-      "Principal": {
-        "RAM": [
-          "acs:ram::1384322691904283:root"
-        ],
-        "Service": [
-          "fc.aliyuncs.com"
-        ]
-      }
-    }
-  ],
-  "Version": "1"
-}
-```
-
-***
-
-### 场景1: 调用JAVA NLP 的离线模型：
-
-#### &#x20;1. 编写代码
-
-* 基于 Hive UDF API 编写 UDF，以下是实现大小写转换的示例代码:
-
-```java
-package com.example;
-
-import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
-import org.apache.hadoop.hive.ql.metadata.HiveException;
-import org.apache.hadoop.hive.ql.udf.generic.GenericUDF;
-import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspector;
-import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector;
-import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector.PrimitiveCategory;
-import org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory;
-
-import java.util.Locale;
-
-public class GenericUdfUpper extends GenericUDF {
-  @Override
-  public ObjectInspector initialize(ObjectInspector[] arguments) throws UDFArgumentException {
-    checkArgsSize(arguments, 1, 1);
-    checkArgPrimitive(arguments, 0);
-    if (((PrimitiveObjectInspector) arguments[0]).getPrimitiveCategory() != PrimitiveCategory.STRING) {
-      throw new UDFArgumentException("argument 0 requires to be string rather than " + arguments[0].getTypeName());
-    }
-    return PrimitiveObjectInspectorFactory.javaStringObjectInspector;
-  }
-
-  @Override
-  public Object evaluate(DeferredObject[] arguments) throws HiveException {
-    Object arg = arguments[0].get();
-    if (arg == null) {
-      return null;
-    }
-    return ((String) arg).toUpperCase(Locale.ROOT);
-  }
-
-  @Override
-  public String getDisplayString(String[] children) {
-    return "upper";
-  }
-}
-```
-
-* 编译代码生成 Jar 包和其他依赖文件，打包成 zip 压缩包
-
-#### 2. 上传函数程序包到指定路径
-
-如： `oss://hz-oss-lakehouse/functions/sentiment/UDF_code/SentimentAnalysis.zip`
-
-函数主类：`com.clickzetta.nlp.GenericUDFSentiment`
-
-有两种方法上传文件到指定路径：
-
-* 通过 OSS 客户端直接上传&#x20;
-* 在Lakehouse JDBC 客户端（不支持Lakehouse Web UI 使用 PUT 命令上传）通过 [PUT 命令](PUT.md) 将程序包上传至 [Volume对象](datalake_volume.md)，并在创建函数 DDL 中引用 volume 路径。例如：
-
-```
--- 上传文件到命名为 fc_volume 的 Volume对象：
-PUT ./SentimentAnalysis.zip to volume fc_volume/udfs/SentimentAnalysis.zip;
-
--- 在创建函数时引用该 Volume 路径：
-create external function public.sentiment_demo_hz
-    AS 'com.clickzetta.nlp.GenericUDFSentiment' 
-    USING ARCHIVE 'volume://fc_volume/udfs/SentimentAnalysis.zip' 
-    CONNECTION udf_sentiment_bj
-    WITH
-    PROPERTIES (
-        'remote.udf.api' = 'java8.hive2.v0'
-);
-
-```
-
-您也可以指定内部 volume。虽然您可以使用内部 volume，但是在创建 API CONNECTION 中的 code_bucket 参数必须填写外部地址。
-
-* **User Volume 格式地址**:`volume:user://~/upper.jar`
-  * `user` 表示使用 User Volume 协议。
-
-  * `~` 表示当前用户，为固定值。
-
-  * `upper.jar` 表示目标文件名。
-* **Table Volume 格式地址**`volume:table://table_name/upper.jar`
-  * `table` 表示使用 Table Volume 协议。
-  * `table_name` 表示表名，需根据实际情况填写。
-  * `upper.jar` 表示目标文件名。
-
-#### 3. 新建连接（Connection）
-
-```SQL
-create api connection udf_sentiment_bj
-type cloud_function 
-provider = 'aliyun'
-region = 'cn-beijing'
-role_arn = 'acs:ram::1222808864467016:role/czudfrole'
-namespace = 'default'
-code_bucket = 'derek-bj-oss';
-```
-
-**参数解释**：
-
-1. **api_connection**：创建 API 类型的 Connection，用于调用第三方的服务接口；
-
-2. **type**: 连接类型为云函数：cloud\_function，其中具体的属性为：
-
-* provider：云函数提供商，如 aliyun
-* region：云函数所在区域，如'cn-shanghai'
-* role\_arn：创建云函数所扮演的角色，如 acs\:ram::12228000000000000\:role/czudfrole
-* code\_bucket：云函数程序文件所在路径的对象存储 bucket 名称
-
-#### 4.在 Lakehouse 创建 External Function
-
-```SQL
-create external function public.sentiment_demo_hz 
-as 'com.clickzetta.nlp.GenericUDFSentiment' 
-using archive 'oss://hz-oss-lakehouse/functions/sentiment/UDF_code/SentimentAnalysis.zip'
-connection udf_sentiment_hz 
-with properties ( 
- 'remote.udf.api' = 'java8.hive2.v0', 
-);
-```
-
-**参数解释**：
-
-1. **as**：后面跟的是 Java 函数的主类名
-2. **using**：仅支持编译后的 Java 程序。后面需要接参数 **archive** 表示程序包为 zip 格式的文件；**jar** 表示 Java 程序的 jar 包文件。后面可直接引用文件的 OSS 路径；如果文件已通过[PUT 命令](PUT.md)上传至 [Volume对象](datalake_volume.md)，也可以通过 Volume 路径直接引用函数文件，例如：`USING ARCHIVE 'volume://fc_volume/udfs/SentimentAnalysis.zip' `
-3. **connection**：表示程序中使用的 connection 对象，如 udf\_sentiment\_bj；其中属性信息：
-
-* remote.udf.api：java UDF 请填写为 java8.hive2.v0
-
-#### 5. 执行语义情感分析：
-
-**构造测试数据**：
-
-```SQL
-create table tbl_wisdom_nlp(id int, qoute string);
-
-insert into tbl_wisdom_nlp values(1,"Honesty and diligence should be your eternal mates");
-insert into tbl_wisdom_nlp values(2,"If a man deceives me once, shame on him; if twice,shame on me");
-insert into tbl_wisdom_nlp values(3,"I am so damn happy");
-insert into tbl_wisdom_nlp values(4,"Today is Sunday");
-insert into tbl_wisdom_nlp values(5,"Today is Monday");
-```
-
-**执行语义分析**：
-
-```SQL
-set cz.sql.remote.udf.enabled = true;
-select qoute, public.sentiment_demo(qoute) as sentiment from tbl_wisdom_nlp;
-```
-
-## 场景2：Python UDF：调用第三方视觉处理平台 API 做图像解析
-
-#### 1. 代码文件为 video\_contents.py：
-
-```Python
-from alibabacloud_imagerecog20190930.client import Client
-from alibabacloud_imagerecog20190930.models import RecognizeFoodRequest
-from alibabacloud_tea_openapi.models import Config
-from alibabacloud_tea_util.models import RuntimeOptions
-
-from cz.udf import annotate
-
-@annotate("string->string")
-class image_to_text(object):
-
-    def evaluate(self,url):
-        if url is None:
-            return None
-        try:
-            config = Config(
-                access_key_id='xxxxx',
-                access_key_secret='xxxxxxxx',
-                endpoint='imagerecog.cn-shanghai.aliyuncs.com',
-                region_id='cn-shanghai'
-            )
-            # Initialize a request and set parameters
-            
-            client = Client(config)
-            recognize_food_request = RecognizeFoodRequest(image_url=url)
-            runtime = RuntimeOptions()
-            response = client.recognize_food_with_options(recognize_food_request, runtime)
-
-            if len(str(response.body)) >= 1:
-                return str(response.body)
-            else:
-                return ""
-        except Exception as exc:
-            return "[error] " + exc.__str__()
-        finally:
-            pass
-
-#if __name__ == "__main__":
-#   import sys
-#    to_text = image_to_text()
-#    for url in sys.argv[1:]:
-#        print(f"{to_text.evaluate(url)}")
-```
-
-#### 2. 复用*场景一*中的 connection
-
-#### 3. 新建 External Function
-
-```Python
-create external function public.image_to_text
-as 'video_contents.image_to_text'    # 脚本名称 + 类名称
-using archive 'oss://derek-bj-oss/bj_remote_udf/image_to_text/image_to_text.zip'
-connection udf_sentiment_bj2
-with properties (
- 'remote.udf.api' = 'python3.mc.v0',   
-);
-```
-
-**参数解释**:
-
-1. As 后面为python 模块名 + 主类名，如主程序文件为 video\_contents.py，主类名为 image\_to\_text，as 后的参数为`'video_contents.image_to_text'`
-2. **using archive / file**：py 文件需打包为 zip 格式的文件；同时支持单文件脚本，用 file 参数指定
-
-* **connection**：表示程序中使用的 connection 对象，如 udf\_sentiment\_bj；其中属性信息：
-
-  * remote.udf.api：Python 语言函数请填写 python3.mc.v0
-
-#### 4. 建测试数据验证
-
-将以下4个图片导入到 OSS 中，并生成 public url 存储到 Lakehouse 表中。可以直接用以下 SQL 构造测试表：
-
-```SQL
-create table tbl_images(id int, url string);
-
-insert into tbl_images values(1,'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood1.jpg');
-insert into tbl_images values(2,'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood2.jpg');
-insert into tbl_images values(3,'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood3.jpg');
-insert into tbl_images values(4,'http://viapi-test.oss-cn-shanghai.aliyuncs.com/viapi-3.0domepic/imagerecog/RecognizeFood/RecognizeFood4.jpg');
-```
-
-执行查询：
-
-```SQL
-set cz.sql.remote.udf.enabled = true;
-select id, public.image_to_text(url) from tbl_images;
-```

-# External Function 开发指南（Python3）
-
-## 目标：
-
-本文目标是帮助开发者掌握用 Python 语言编写外部函数处理云器 Lakehouse 中的数据。
-
-## 注意事项：
-
-> * **Python 版本**： 仅支持 Python 3.10。若依赖包含共享对象文件（.so）的原生库，此类库必须与 Python 3.10 ABI (Application Binary Interface) 兼容。
-> * **部署包格式**： 支持独立的 `.py` 脚本文件，或以 `.zip` 格式归档的程序包。
-> * **大型程序包部署**： 若程序及其依赖项压缩后总体积超过 500MB，则必须通过容器镜像方式创建函数。具体操作请参阅教程：[实践：利用Hugging Face 图片识别模型处理图片数据](RemoteFunctionOnACR.md)
-
-## 环境准备：
-
-鉴于 External Function 的上述使用限制，对开发环境有如下具体要求和建议：
-
-1. **无第三方库依赖**：
-   如果您的 Python 脚本不依赖任何第三方库，仅需确保代码具备下文规定的代码结构，且能够在 Python 3.10 环境中正确执行即可。
-
-2. **有第三方库依赖**：
-   如果脚本需要第三方库，则这些依赖库（及其二进制文件）必须与 Python 3.10 ABI (x86\_64 架构) 兼容。
-
-> **跨平台兼容性**： 在 macOS 或 Windows 等非 Linux x86\_64 环境中开发时，Python 依赖库的 ABI 兼容性问题较为常见。为确保一致性和避免潜在错误，强烈推荐使用以下容器镜像作为 Python External Function 的标准开发环境：
-> `quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779`。该镜像提供了预配置的、符合要求的 Linux x86\_64 以及 Python 3.10 的环境。镜像安装请参考本篇文档最后的附录：开发环境镜像安装。
->
-> &#x20;如果您的开发环境本身即为 x86\_64 架构的 Linux 系统，则仅需确保 Python 版本为 3.10 版本即可。
-
-## 代码结构：
-
-Python 函数的代码结构分为以下几个部分：
-
-* **导入模块**：必选。至少要包含 `from cz.udf import annotate`，导入函数签名模块，云器Lakehouse 才可以识别后续代码中定义的函数签名。
-* **函数签名**：必选。格式为 `@annotate(<signature>)`，`signature`用于定义函数的输入参数和返回值的数据类型。更多函数签名信息。
-* **自定义Python类**：必选。UDF代码的组织单位，定义了实现业务需求的变量及方法。您还可以在代码中引用第三方库或引用文件、表资源。
-* **evaluate** **方法**：必选。位于自定义的Python类中。`evaluate`方法定义了输入参数和返回值。一个Python类中只能包含一个`evaluate`方法。
-
-> 基于上述代码结构，实现一个将字符转换为大写的函数代码如下：
-
-```Python
-#!/usr/bin/env python
-try:
-    from cz.udf import annotate  # 导入模块
-except ImportError:
-    annotate = lambda _: lambda _: _
-
-@annotate("string->string")  # 函数签名
-class Upper(object):         # 自定义 Python 类
-    def evaluate(self, arg):  # evaluate 方法
-        if arg is None:  
-            return None
-        return arg.upper()
-```
-
-## 安装第三方库：
-
-以下载 httpx 和 pydantic 为例，使用下面命令将依赖包下载到主程序文件所在的目录（例子为当前目录）
-
-```Shell
-pip3 install httpx pydantic -t . 
-```
-
-> 注意：当您使用 macOS / Windows 等非 Linux 系统, 或者使用非 X86-64 的设备，或者使用第三方库包含原生代码时，为避免 Python ABI 兼容性问题，强烈建议使用基于 `quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779` 的容器下载第三方依赖，请参考附录：开发环境镜像安装。
-
-## 上传函数
-
-### 上传、压缩包上传
-
-仅适用于打包之后小于 500M 的函数，大于 500M 请参考后续章节：利用镜像方式创建函数
-
-将程序文件、依赖库文件或者模型文件打包为 zip 格式（当前仅支持 zip 格式文件且小于 500M ），例如
-
-```Shell
-cd ./deps
-zip -rq code.zip ./*
-```
-
-将 code.zip 上传至云上对象存储，并授权给云器Lakehouse 的云上角色能访问到对应路径；授权流程不在开发指南中描述，请参考[使用流程：External Function](RemoteFunctionBestPractice.md)。
-您也可以指定内部volume。虽然您可以使用内部volume但是您在创建API CONNECTION中的code bucket参数必须填写外部地址。
-
-* **User Volume 格式地址**： `volume:user://~/upper.jar`
-  * `user` 表示使用 User Volume 协议。
-
-  * `~` 表示当前用户，为固定值。
-
-  * `upper.jar` 表示目标文件名。
-* **Table Volume 格式地址**：`volume:table://table_name/upper.jar`
-  * `table` 表示使用 Table Volume 协议。
-  * `table_name` 表示表名，需根据实际情况填写。
-  * `upper.jar` 表示目标文件名。
-
-### 镜像方式上传：
-
-仅适用于打包之后大于 500M 、或使用 GPU 资源的函数；需要开通阿里云容器镜像服务（免费）
-
-请参考文档：[实践：利用Hugging Face 图片识别模型处理图片数据](RemoteFunctionOnACR.md)
-
-^
-
-## 示例：
-
-目标：利用大语言模型（LLM）服务，根据 Lakehouse 客户表中的**公司名称**列，填写国家规范的所属**一级行业**和**二级行业的信息**。效果如下：
-
-![](.topwrite/assets/20250612-171447.jpeg =675)
-
-> 注意：完成本示例，需要您：
->
-> 1. 安装了 Docker （主要是为了保证开发环境与云器运行函数的环境一致）
-> 2. 拥有阿里云账号，并开通百炼平台的 API-KEY。参考 [阿里云百炼](https://www.aliyun.com/product/bailian)
-> 3. 已经创建好 API 连接。参考：创建 [API 连接](create-api-connection.md)
-
-### Step1：准备开发环境
-
-1. **安装 Docker**：确保您的本地上安装了 Docker：<https://www.docker.com/>
-
-2. **拉取** **Docker** **镜像**。在本地命令行终端（如 MacOS 的 ternmial）执行：
-
-   ```
-   [Local]# docker pull quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779
-   ```
-
-3. **启动 Docker 容器**。该容器基于 `manylinux2014_x86_64` 镜像，并配置为使用 Python 3.10 环境
-
-   ```
-   [Local]# docker run -it --name cz_func --env PATH="/opt/python/cp310-cp310/bin:$PATH" quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779 bash
-   ```
-
-> 如果容器已经停止，可以用以下命令启动并登录：
->
-> 1. **启动容器**：
->
-> ```
-> # docker start cz_func
-> ```
->
-> 2. **进入容器**：
->
-> ```
-> # docker exec -it cz_func bash
-> ```
-
-&#x20;    4\.  在 /root 目录下创建文件夹 cz\_llm
-
-```
-[root@docker root]# cd /root ; mkdir cz_llm 
-[root@docker cz_llm]# cd cz_llm
-[root@docker cz_llm]# touch cz_llm.py
-```
-
-&#x20;   5\. `cz_llm.py` 中的程序代码如下：
-
-```
-import os
-from cz.udf import annotate
-import dashscope
-from http import HTTPStatus
-import json
-import sys
-
-@annotate("*->string")
-class llm_call(object):
-    def evaluate(self, text, prompt, api_key, model_name, temperature=0.7, enable_search=False):
-
-        # 设置 API 密钥
-        dashscope.api_key = api_key
-
-        # 构建消息
-        messages = [
-            {"role": "system", "content": prompt},
-            {"role": "user", "content": text}
-        ]
-
-        try:
-            # 调用模型（非流式输出）
-            response = dashscope.Generation.call(
-                model=model_name,
-                messages=messages,
-                stream=False,  # 关闭流式输出
-                result_format='message',
-                temperature=temperature,
-                enable_search=enable_search,
-                top_p=0.8
-            )
-
-            # 处理响应
-            if response.status_code == HTTPStatus.OK:
-                # 非流式输出直接获取完整内容
-                if hasattr(response.output, 'choices') and len(response.output.choices) > 0:
-                    if hasattr(response.output.choices[0].message, 'content'):
-                        return response.output.choices[0].message.content
-                    else:
-                        return "Error: No content in response"
-                else:
-                    return "Error: No choices in response"
-            else:
-                # 返回错误信息
-                return f"Error: Request id: {response.request_id}, Status code: {response.status_code}, error code: {response.code}, error 
-message: {response.message}"
-
-        except Exception as e:
-            # 返回错误信息
-            return f"Error: {str(e)}"
-
-# 测试代码
-if __name__ == "__main__":
-    # 创建实例
-    llm = llm_call()
-    
-    # 配置参数
-    API_KEY = "sk-xxxxxx"  # 替换为你的API密钥
-    MODEL_NAME = "qwen-max"  # 或 qwen-plus, qwen-max 等
-    
-    # 测试示例
-    test_text = '小红书'
-    test_prompt = '请返回该公司的国家规范的一级、二级行业，直接输出结果:一级行业":"xxx","二级行业":"xxx"，言简意赅'
-    
-    print("正在调用LLM...")
-    result = llm.evaluate(test_text, test_prompt, API_KEY, MODEL_NAME, 0, True)
-    
-    print(f"\n输入文本: {test_text}")
-    print(f"系统提示: {test_prompt}")
-    print(f"LLM响应: {result}")
-```
-
-### Step2：下载第三方库
-
-程序依赖第三方包：`dashscope` 需要进行下载（其余为Python 内置， `os`、`http`、`json`、`sys` 为 Python 内置库无需下载。 `cz.udf `创建函数时系统会默认添加）
-
-在开发环境中的命令行终端执行：
-
-```
-[root@docker cz_llm]# pwd
-/root/cz_llm
-
-[root@docker cz_llm]# pip install dashscope -t .
-```
-
-此时目录结构类似于：
-
-![](.topwrite/assets/external_func_2.jpeg)
-
-^
-
-### Step3：本地调试
-
-将以3行做修改，因为当前环境还没有加载 `cz.udf` 库：
-
-```
-...
-2 #from cz.udf import annotate   # 注释掉
-...
-8 #@annotate("*->string")  # 注释掉
-...
-56 API_KEY = "sk-xxxxxx"  # 替换为你的API密钥
-```
-
-其中 API\_KEY 是阿里云百炼平台的 API-KEY ，需要您注册阿里云账号，登录后在这里获取：[阿里云百炼](https://bailian.console.aliyun.com/?spm=5176.12818093_47.console-base_search-panel.dtab-product_sfm.60852cc9WIq2Db\&scm=20140722.S_sfm._.ID_sfm-RL_%E5%A4%A7%E6%A8%A1%E5%9E%8B%E6%9C%8D%E5%8A%A1%E5%B9%B3%E5%8F%B0%E7%99%BE%E7%82%BC%E6%8E%A7%E5%88%B6%E5%8F%B0-LOC_console_console-OR_ser-V_4-P0_0\&tab=api#/api)
-
-注释掉上面两行之后，保存退出编辑脚本。执行：
-
-```
-[root@docker cz_llm]# export PYTHONPATH="${_PWD}:${_PWD}/lib"
-[root@docker cz_llm]# python cz_llm.py 
-正在调用LLM...
-
-输入文本: 小红书
-系统提示: 请返回该公司的国家规范的一级、二级行业，直接输出结果:一级行业":"xxx","二级行业":"xxx"，言简意赅
-LLM响应: "一级行业":"互联网","二级行业":"社交媒体"
-```
-
-### Step4：打包上传
-
-打包之前，请将上面注释掉的两行，解除注释。
-
-```
-...
-2 from cz.udf import annotate   # 去掉注释
-...
-8 @annotate("*->string")  # 去掉注释
-```
-
-执行打包命令，保证当前目录为程序目录（本示例为 `/root/cz_llm`）
-
-```
-[root@docker cz_llm]# pwd
-/root/cz_llm
-[root@docker cz_llm]# zip -rq ../cz_llm.zip ./
-[root@docker cz_llm]# ls ../
-```
-
-> 提示：如果您的环境没有 zip 命令，请利用 yum install zip 尝试下载。下载过程中遇到问题，请参考附录”**安装工具时报错**“
-
-您会发现在 `/root `目录下有一个 `cz_llm.zip` 文件，将这个文件拷贝到 Lakehouse USER VOLUME 对象中：
-
-在 Docker 宿主机中执行：
-
-```
-[Local]# docker cp cz_func:/root/cz_llm.zip ~/Downloads
-```
-
-现在 `cz_llm.zip `在宿主机的用户的 `Downloads` 目录下
-
-我们用 Lakehouse JDBC 客户端（请参考 [Lakehouse JDBC 客户端](connect-with-cli.md)），将文件 put 到 Lakehouse USER VOLUME 中：
-
-```
-PUT '/Users/derekmeng/Downloads/transform_company_id.zip' to USER VOLUME;
-```
-
-![](.topwrite/assets/external_functions_3.jpeg)
-
-### Step5：创建并使用函数：
-
-本步骤依赖您提前创建好 API connection，创建过程请参考：[API Connection ](create-api-connection.md)
-
-```
-CREATE EXTERNAL FUNCTION public.fc_cz_llm
-    AS 'cz_llm.llm_call'   -- 不带py后缀的主程序文件名.主类名
-    USING ARCHIVE 'volume:user://~/cz_llm.zip' 
-    connection sg_fc_api_conn -- 需要提前创建 API Connection
-    WITH PROPERTIES (
-        'remote.udf.api' = 'python3.mc.v0'
-    )
-COMMENT 'Usage: python get_industry_classification.py <text> <prompt> <api_key> <model_name> [temperature] [enable_search]';
-```
-
-创建过程会持续1分钟左右。创建完成后，执行验证函数：（注意替换 `'${api_key}'` ）
-
-```
-SELECT    public.fc_cz_llm (
-          '云器科技',
-          '请返回国家通用的行业分类，返回JSON 并用中文：{"一级行业":"xxx","二级行业":"xxx"}',
-          '${api_key}',
-          'qwen-plus',
-          '0.4',
-          'true'
-          ) AS llm_result;
-```
-
-执行效果：
-
-![](.topwrite/assets/external_function_4.jpeg =660)
-
-## 附录：
-
-### 函数签名：
-
-函数签名格式如下。
-
-```Python
-@annotate(<signature>)
-```
-
-`signature`为字符串，用于标识输入参数和返回值的数据类型。执行UDF时，UDF函数的输入参数和返回值类型要与函数签名指定的类型一致。查询语义解析阶段会检查不符合函数签名定义的用法，检查到类型不匹配时会报错。具体格式如下。
-
-```Python
-'arg_type_list -> type'
-```
-
-其中：
-
-* `arg_type_list`：表示输入参数的数据类型。输入参数可以为多个，用英文逗号（,）分隔。支持的数据类型为BIGINT、STRING、DOUBLE、BOOLEAN、DATETIME、DECIMAL、FLOAT、BINARY、DATE、DECIMAL(precision,scale)、CHAR、VARCHAR、复杂数据类型（ARRAY、MAP、STRUCT）或复杂数据类型嵌套。
-
-* `arg_type_list`还支持星号（\*）或为空（''）：
-
-  * 当`arg_type_list`为星号（\*）时，表示输入参数为任意个数。
-  * 当`arg_type_list`为空（''）时，表示无输入参数。
-
-* `type`：表示返回值的数据类型。UDF只返回一列。支持的数据类型为：BIGINT、STRING、DOUBLE、BOOLEAN、DATETIME、DECIMAL、FLOAT、BINARY、DATE、DECIMAL(precision,scale)、复杂数据类型（ARRAY、MAP、STRUCT）或复杂数据类型嵌套。
-
-合法的函数签名示例如下：
-
-| 函数签名示例                                        | 说明                                                       |
-| --------------------------------------------- | -------------------------------------------------------- |
-| `'bigint,double->string'`                     | 输入参数类型为BIGINT、DOUBLE，返回值类型为STRING。                       |
-| `'*->string'`                                 | 输入任意个参数，返回值类型为STRING。                                    |
-| `'->double'`                                  | 无输入参数，返回值类型为DOUBLE。                                      |
-| `'array<bigint> -> struct<x:string>, y:int>'` | 输入参数类型为ARRAY\<BIGINT>，返回值类型为STRUCT\<x\:string>, y\:int>。 |
-| '->map\<bigint, string>'                      | 无输入参数，返回值类型为MAP\<BIGINT, STRING>。                        |
-
-### 数据类型：
-
-为确保编写Python UDF过程中使用的数据类型与云器 Lakehouse 支持、的数据类型保持一致，您需要关注二者间的数据类型映射关系：
-
-| 云器 Lakehouse 数据类型 | Python 3 数据类型          |
-| ----------------- | ---------------------- |
-| BIGINT            | int                    |
-| BOOLEAN           | bool                   |
-| CHAR              | unicode                |
-| DATE              | datatime.date          |
-| DECIMAL           | decimal.Decimal        |
-| DOUBLE            | float                  |
-| FLOAT             | float                  |
-| INT               | int                    |
-| SMALLINT          | int                    |
-| STRING            | str                    |
-| TIMESTAMP\_LTZ    | datetime.datetime      |
-| TINYINT           | int                    |
-| ARRAY             | list                   |
-| MAP               | list                   |
-| STRUCT            | collections.namedtuple |
-| VARCHAR(n)        | str(超限写入失败)            |
-| VOID              | NoneType               |
-
-### 开发环境镜像安装：
-
-> **适用场景：在非 Linux/非 X86-64 环境或使用含原生代码的第三方库时规避 Python ABI 兼容性问题**
-
-在软件开发过程中，尤其是在使用 Python 进行跨平台或涉及底层原生代码交互时，应用程序二进制接口（ABI）的兼容性问题是一个需要重点关注的方面。当您的开发或部署环境为 macOS、Windows 等非 Linux 系统，或者目标设备架构并非 X86-64（例如 ARM 架构的设备），亦或是项目中引入了包含 C/C++ 等原生代码编译的第三方库时，潜在的 ABI 不兼容风险会显著增加。为了确保 Python 应用的稳定性和可移植性，强烈建议采用标准化的构建环境来下载和编译这些第三方依赖。
-
-**推荐实践：使用** \`\` **容器**
-
-对于提示中提到的具体场景，即在非 Linux 系统（如 macOS、Windows）、非 X86-64 设备，或使用包含原生代码的第三方库时，为了规避 Python ABI 兼容性问题，强烈建议使用基于 `quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779` 的 Docker 容器来下载和构建第三方依赖。
-
-#### **如何操作**：
-
-1. **安装 Docker**：确保您的开发机器上安装了 Docker：<https://www.docker.com/>
-
-2. **拉取镜像**：
-
-   ```
-   docker pull quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779
-   ```

-3. 启动 Docker 容器，该容器基于 `manylinux2014_x86_64` 镜像，并配置为使用 Python 3.10 环境
-
-   ```
-   docker run -it --name cz_func --env PATH="/opt/python/cp310-cp310/bin:$PATH" quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779 bash
-   ```
-
-这样就可以在该环境中，以 Python 3.10 来开发您的 Python 外部函数了。
-
-> 如果容器已经停止，可以用以下命令启动并登录：
->
-> 1. **启动容器**：
->
-> ```
-> docker start cz_func
-> ```
->
-> 2. **进入容器**：
->
-> ```
-> docker exec -it cz_func bash
-> ```
->
-> ^
-
-^
-
-然后您应该会看到容器内的 Bash 提示符(提示符的具体样式可能因镜像而异)，例如打印 Python 版本，此时应该显示如下：
-
-```
-[root@cfadeae5f8b0 /]# python --version
- Python 3.10.8
-```
-
-现在您应该已经成功 "登录" 到您的 `cz_func` 容器中了。
-
-^
-
-#### **镜像使用常见问题**：
-
-1\. **安装工具时报错**
-
-&#x20;   如 `yum install zip` 安装 `zip` 打包工具 ，会遇到诸如下面的错误：
-
-```
-[root@311b32ae3e5f ]# yum install zip
-Loaded plugins: fastestmirror, ovl
-Determining fastest mirrors
-Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was
-14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"
-
-
- One of the configured repositories failed (Unknown),
- and yum doesn't have enough cached data to continue. At this point the only
- safe thing yum can do is fail. There are a few ways to work "fix" this
-...
-            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
-
-Cannot find a valid baseurl for repo: base/7/x86_64
-```
-
-这个错误是因为 CentOS 7 已经在 2024 年 6 月 30 日到达生命周期终点（EOL），官方仓库已经被移到 CentOS vault。`mirrorlist.centos.org` 不再提供 CentOS 7 的仓库服务。
-
-以下是解决方案：
-
-首先，检查网络连接是否正常：
-
-如果网络正常，更新仓库配置以使用 CentOS vault：
-
-```
-# 备份当前的仓库文件
-mkdir -p /etc/yum.repos.d/backup
-cp /etc/yum.repos.d/CentOS-*.repo /etc/yum.repos.d/backup/
-
-# 更新仓库 URL 以使用 vault.centos.org
-sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*.repo
-sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*.repo
-
-# 清理 yum 缓存
-yum clean all
-
-# 现在再次尝试安装 zip
-yum install zip
-```
-
-如果您在中国或者 **vault.centos.org** 访问较慢，可以使用国内镜像源：
-
-使用阿里云镜像：
-
-```
-sed -i 's|baseurl=http://vault.centos.org|baseurl=http://mirrors.aliyun.com/centos-vault|g' /etc/yum.repos.d/CentOS-*.repo
-```
-
-或者使用清华大学镜像：
-
-```
-sed -i 's|baseurl=http://vault.centos.org|baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos-vault|g' /etc/yum.repos.d/CentOS-*.repo
-```
-
-完成这些更改后，`yum install zip` 命令应该就能正常工作了。
-
-^
-
-**2**. **Docker 容器与宿主机文件互拷**
-
-生成了程序包，如果想从容器中拷贝到宿主机，或者反过来从宿主机拷贝到容器中，可以使用下面的命令：
-
-**从容器拷贝到宿主机**：
-
-```
-# docker cp 容器名:容器内路径 宿主机路径，示例：
-docker cp cz_func:/root/gen_emmbedings.zip ~/Downloads
-```
-
-**从宿主机拷贝到容器**：
-
-```
-# docker cp 宿主机路径 容器名:容器内路径# 示例
-docker cp ~/Downloads/file.txt cz_func:/root/
-```
-
-**注意**：
-
-* 容器可以是运行中或已停止状态
-* 使用容器名或容器ID都可以
-* 支持拷贝文件和目录：`docker cp` 会自动识别是文件还是目录
-
-```
-# 拷贝整个目录
-docker cp ~/project 容器名:/root/
-# 拷贝目录内容
-docker cp ~/project/. 容器名:/root/project/
-```
-
-^
-
-* `docker cp` 会自动识别是文件还是目录
-
-* 拷贝目录时会递归拷贝所有子目录和文件
-
-* 目标路径不存在时会自动创建
-
-* 路径末尾加 `/` 与不加的区别：
-
-  * `/app/logs` → 拷贝 logs 目录本身
-  * `/app/logs/.` → 只拷贝 logs 目录下的内容
-

-# 利用Hugging Face 图片识别模型处理图片数据
-
-## 1. 适用场景：
-
-本文创建 Remote Function 的方式是基于阿里云容器镜像创建，这个场景适用于：
-
-* 如果图像解析程序的 Python 依赖包大于 500M，就需要利用本文介绍的方式，即基于容器镜像服务方式创建（如果函数的程序文件包小于 500M，可直接传到对象存储走自动化创建）。
-* 无论程序文件大小，需要使用云上函数计算服务的 GPU 资源时，需要基于容器镜像服务方式创建
-
-## 2.过程演示：

-  * repo\_id 为模型名称：参考模型网站：
-
-  ![](.topwrite/assets/remote_udf_image01.jpeg)
-
-  * local\_dir: 本地文件夹，为模型下载的目的地
-  * local_dir_use_symlinks：本地文件夹是否为 mount 点
-
-```Python
-from huggingface_hub import snapshot_download
-repo_id = 'nlpconnect/vit-gpt2-image-captioning'  
-local_dir = './model'
-local_dir_use_symlinks = False
-snapshot_download(repo_id=repo_id, local_dir=local_dir, local_dir_use_symlinks=local_dir_use_symlinks)
-```
-
-#### 2.2.2 下载依赖库：
-
-下载依赖库到 `lib_` 目录 (需要使用 python 特定版本, 建议使用 docker)
-
-将本地创建 `lib_ `文件夹，mount 到 docker 的 `/root/lib_ `，将依赖库下载到`lib_` 中
-
-```Python
-docker run -it -v `pwd`/lib_:/root/lib_ quay.io/pypa/manylinux2014_x86_64:2022-10-25-fbea779 /bin/bash
-```
-

-# EXTERNAL FUNCTION
-
-## 概述
-
-EXTERNAL FUNCTION（REMOTE FUNCTION）是在云器 Lakehouse 中通过 Python 和 Java 语言创建的自定义函数（UDF），通过远程服务执行（支持的远程服务包括：阿里云的函数计算 FC、腾讯云的云函数 SCF）。在执行过程中可调用：
-
-* 在线服务：以 API 形式对外提供的在线服务，例如：AI 在线模型服务（如大语言模型 API、云平台提供的在线 AI API 服务）。
-* 离线功能：将特定功能函数代码、依赖库、模型和数据等文件打包成的离线服务包，例如从 Hugging Face 下载的图片识别模型等。
-
-云器 Lakehouse 通过创建 API CONNECTION，在元数据中保存外部函数计算服务的连接和访问信息。EXTERNAL FUNCTION 通过 HTTP 协议调用外部函数计算服务进行数据处理，并返回结果。
-![](.topwrite/assets/a7546df1-be39-41e9-9c80-e0e90ce3d353.svg)
-云器 Lakehouse 平台通过用户的预先授权，在创建外部函数时，将自动在客户账号下的函数计算服务中创建对应的函数。当用户在 SQL 查询中使用外部函数时，外部函数会实现与外部计算服务的安全连接、数据处理，并返回查询结果。
-
-## EXTERNAL FUNCTION 创建流程
-
-请参考：[使用流程: External Function](RemoteFunctionBestPractice.md)
-
-* 用户开通云上的函数计算服务（如阿里云的函数计算 FC）和对象存储服务。
-* 将函数执行代码、可执行文件、依赖库、模型和数据文件打包上传至对象存储。
-* 授予云器 Lakehouse 操作上述服务和访问函数文件（包）的权限。
-* 用户执行连接和外部函数 DDL 语句以生成 UDF，并在查询中使用。
-
-## EXTERNAL FUNCTION 执行过程
-
-* 用户在云器 Lakehouse SQL 语句中调用 External Function。
-* 云器 Lakehouse 根据提供的服务地址和认证信息，发送 HTTP 请求以调用并运行函数。
-* 云器 Lakehouse 获取响应信息并返回结果。
-
-## EXTERNAL FUNCTION 优势
-
-* 可以使用 Remote Function 调用外部丰富的数据处理能力，以补充传统 SQL 计算模型。例如，可调用大语言模型（LLM）、图像处理、音视频处理等服务或能力，以补充 SQL 在非结构化数据处理方面的能力。
-* 可以直接访问外部网络，不受云器 Lakehouse 网络约束。
-
-## 使用限制
-
-* 目前只支持 Java 和 Python 编程语言，支持的运行环境为 Java 8 和 Python 3.10。
-* 如果依赖原生库（如包含 .so 文件的库），需要兼容 Python 3.10 的 ABI。
-* 当程序及其依赖文件压缩后大于 500 MB 时，需要以容器镜像方式创建函数，请参考[实践：利用Hugging Face 图片识别模型处理图片数据](RemoteFunctionOnACR.md)。
-
-## EXTERNAL FUNCTION 收费
-
-* 支持自定义函数类型：UDF，UDAF，UDTF
-* 远程服务调用的费用：参考云厂商的函数计算服务费用信息（阿里云请参考[链接](https://help.aliyun.com/zh/fc/product-overview/billing-overview?spm=a2c4g.11186623.0.0.4d5b19b3rrOy7Y)，腾讯云请参考[链接](https://cloud.tencent.com/document/product/583/17299)）。
-* 使用云器 Lakehouse 的计算资源所产生的计算费用。
-* 数据传输费用：任何涉及公网数据流出的费用。内网传输不产生费用。
-
-## 使用 REMOTE FUNCTION 开发 UDF 函数
-
-请参考以下开发指南：
-
-* [External Function(Java)](ExternalFunctionDevGuideJava.md)
-* [External Function(Python3)](RemoteFunctionDevGuidePython3.md)

-## 功能
-
-本命令用于回收指定角色的权限。通过使用 REVOKE 语句，可以对不同级别的权限进行回收，包括 workspace、workspace 对象、schema 和 schema 对象等级别。
-
-## Workspace 用户和角色权限管理语法
-
-```SQL
-REVOKE [workspacePrivileges | workspaceObjectPrivileges | schemaPrivileges | schemaObjectPrivileges]
-ON [WORKSPACE | {ROLE | SCHEMA | VCLUSTER | DATALAKE | FUNCTION | workspace_object_name | SCHEMA | {TABLE | VIEW | MATERIALIZED VIEW} schema_object_name]
-FROM ROLE role_name;
-```
-
-### 参数说明
-
-1.  **workspacePrivileges**：在 workspace 下创建对象的权限，例如 `CREATE SCHEMA` 和 `CREATE VCLUSTER`。
-
-2.  **workspaceObjectPrivileges**：对 workspace 下对象的修改和查看元数据等权限，例如 `ALTER`、`DROP`、`READ METADATA` 和 `ALL [PRIVILEGES]`。
-
-3.  **schemaPrivileges**：在 schema 下创建对象的权限，例如 `CREATE TABLE`、`CREATE VIEW` 和 `CREATE MATERIALIZED VIEW`。
-
-4.  **schemaObjectPrivileges**：对 schema 下对象的修改、删除、查询等权限，例如 `ALTER`、`DROP`、`SELECT`、`INSERT`、`READ METADATA` 和 `ALL`。
-
-## 示例
-
-1.  回收角色 `simple_role` 在 `lakehouse_public` workspace 下创建 `VIRTUAL CLUSTER` 的权限：
-
-    ```SQL
-   REVOKE CREATE VCLUSTER ON WORKSPACE lakehouse_public FROM ROLE simple_role;
-   ```
-
-2.  回收角色 `simple_role` 在名为 `default` 的 `VIRTUAL CLUSTER` 上的 `ALTER` 权限：
-
-    ```SQL
-   REVOKE ALTER VCLUSTER ON VCLUSTER default FROM ROLE simple_role;
-   ```
-
-3.  回收角色 `uat_demo` 在 `public` schema 下创建表和视图的权限：
-
-    ```SQL
-   REVOKE CREATE VIEW, CREATE TABLE ON SCHEMA public FROM ROLE uat_demo;
-   ```
-
-4.  回收角色 `reporting_role` 在名为 `sales_data` 的 `DATALAKE` 上的 `READ METADATA` 权限：
-
-    ```SQL
-   REVOKE READ METADATA ON DATALAKE sales_data FROM ROLE reporting_role;
-   ```
-
-5.  回收角色 `admin_role` 在名为 `order_summary` 的 `FUNCTION` 上的 `ALTER` 和 `DROP` 权限：
-
-    ```SQL
-   REVOKE ALTER, DROP ON FUNCTION order_summary FROM ROLE admin_role;
-   ```
-
-6.  回收角色 `analyst_role` 在 `public` schema 下名为 `customer_orders` 的 `TABLE` 上的 `SELECT` 和 `INSERT` 权限：
-
-    ```SQL
-   REVOKE SELECT, INSERT ON TABLE public.customer_orders FROM ROLE analyst_role;
-   ```
-
-
-
-# Instance Role 权限管理
-LakeHouse 支持对 Instance Role 的跨工作空间权限进行细粒度回收，确保权限管控的灵活性和安全性。
-
-## 语法说明
-```sql
--- 回收 Instance Role 对工作空间的权限  
-REVOKE <privilege> ON WORKSPACE <workspace_name> FROM INSTANCE ROLE <role_name>;  
-
--- 回收 Instance Role 对表/库的权限  
-REVOKE <privilege> ON TABLE <workspace>.<schema>.<table> FROM INSTANCE ROLE <role_name>;  
-
-REVOKE <privilege> ON DATABASE <workspace>.<schema> FROM INSTANCE ROLE <role_name>;  
-
--- 移除用户的 Instance Role 归属  
-REVOKE INSTANCE ROLE <role_name> FROM USER <user_name>;  
-```
-

-# SCHEMA
-
-在数据库设计中，SCHEMA是组织和管理数据的关键概念。它为用户提供了一种灵活的方式来定义数据的结构和关系。通过使用 SCHEMA，可以将相关的数据库对象（如表、视图等）进行逻辑分组，使得数据组织更加清晰，便于维护和扩展。
-
-## SCHEMA的主要作用
-
-1. **逻辑分组**：SCHEMA允许用户根据业务功能、数据类型或其他标准，将数据库对象进行逻辑分组，从而实现数据的有序组织。
-2. **权限管理**：通过SCHEMA，可以对数据库对象实施更精细的权限控制。用户可以针对不同的SCHEMA设置相应的访问权限，以实现安全管理。
-3. **命名空间**：SCHEMA 提供了命名空间功能，有助于避免对象名称的冲突。在大型项目或多用户环境中，这一点尤为重要。
-4. **简化操作**：用户可以通过 `USE` 命令快速切换当前操作的 SCHEMA，简化了日常数据库操作，提高了工作效率。
-
-## SCHEMA管理命令
-
-云器 Lakehouse 提供了一系列的命令来管理 SCHEMA，包括创建、删除、查看详情、切换以及列举等。
-
-* [创建SCHEMA](CREATESCHEMA.md)：使用 `CREATE SCHEMA` 命令可以创建一个新的 SCHEMA。例如，`CREATE SCHEMA myschema;` 会创建一个名为 `myschema` 的 SCHEMA。
-* [删除SCHEMA](DROPSCHEMA.md)：如果某个 SCHEMA 不再需要，可以使用 `DROP SCHEMA` 命令将其删除。执行删除操作前，请确保已对相关数据进行备份或迁移，以防止数据丢失。
-* [查看SCHEMA详情](DESCSCHEMAS.md)：通过 `DESC SCHEMAS` 命令，用户可以查看当前空间中所有 SCHEMA 的详细信息，包括创建时间、对象数量等。
-* [切换SCHEMA](USESCHEMA.md)：使用 `USE SCHEMA` 命令可以切换当前会话的默认 SCHEMA。例如，`USE SCHEMA myschema;` 会将 `myschema` 设置为当前会话的默认 SCHEMA。
-* [列举当前空间所有SCHEMA](show-schemas.md)：通过 `SHOW SCHEMAS` 命令，用户可以列举出当前空间中所有的 SCHEMA，便于管理和选择。
-* [修改SCHEMA](<ALTER-SCHEMA.md>)：支持修改 SCHEMA 的属性和重命名 SCHEMA。
-
-## 应用示例
-
-以下是一个应用示例，展示了如何创建和切换 SCHEMA：
-
-```sql
--- 创建一个新的SCHEMA
-CREATE SCHEMA myschema;
-
--- 在创建表时指定SCHEMA
-CREATE TABLE myschema.mytable (
-    id INT PRIMARY KEY,
-    name VARCHAR(50)
-);
-
--- 切换到刚刚创建的SCHEMA
-USE SCHEMA myschema;
-
--- 在当前SCHEMA下查询表结构
-DESC TABLE mytable;
-
--- 向表中插入数据
-INSERT INTO myschema.mytable (id, name) VALUES (1, '张三');
-
--- 查询表中的数据
-SELECT * FROM myschema.mytable;
-```

-   CREATE TABLE example_table (
-       id INT,
-       name VARCHAR(50),
-       smallint_value SMALLINT
-   );
-   ```
-
-2. 向表中插入SMALLINT类型的数据：
-
-   ```sql
-   INSERT INTO example_table (id, name, smallint_value)
-   VALUES (1, '张三', -32768);
-   ```
-
-3. 查询表中的SMALLINT类型数据：
-
-   ```sql
-   SELECT * FROM example_table;
-   ```
-
-4. 使用SMALLINT类型数据进行条件筛选：
-
-   ```sql
-   SELECT * FROM example_table WHERE smallint_value > 0;
-   ```
-
-5. 对SMALLINT类型的数据进行数学运算：
-
-   ```sql
-   SELECT smallint_value + 1 FROM example_table;
-   ```
-
-## 注意事项
-- 请确保插入的数据在SMALLINT类型的有效范围内，否则可能导致数据溢出或截断。
-- 在进行数学运算时，请注意数据类型之间的隐式转换，以避免意外的结果。

-### 核心优势对比
-
-| 特性           | Spark           | Lakehouse  | 优势      |
-| ------------ | --------------- | ---------- | ------- |
-| **建表方式**     | DataFrame API为主 | SQL DDL标准化 | 降低学习成本  |
-| **分区管理**     | 手动管理            | 隐藏分区+转换分区  | 自动优化    |
-| **数据组织**     | 文件级别            | 表级别管理      | 更高效的元数据 |
-| **Schema演进** | 需要重写            | 原地演进       | 灵活性更强   |
-
-### DataFrame到DDL的转换
-
-**Spark DataFrame方式**：
-
-```python
-# Spark DataFrame创建表
-df = spark.read.parquet("path/to/data")
-df.write.partitionBy("year", "month") \
-  .bucketBy(10, "user_id") \
-  .sortBy("timestamp") \
-  .saveAsTable("user_events")
-```
-
-**Lakehouse DDL方式**：
-
-```sql
--- 对应的Lakehouse建表语句
-CREATE TABLE user_events (
-    user_id BIGINT,
-    event_type STRING,
-    timestamp TIMESTAMP,
-    properties MAP<STRING, STRING>,
-    year INT GENERATED ALWAYS AS (year(timestamp)),
-    month INT GENERATED ALWAYS AS (month(timestamp))
-) 
-PARTITIONED BY (year, month)
-CLUSTERED BY (user_id) SORTED BY (timestamp) INTO 10 BUCKETS
-COMMENT '用户事件表';
-```
-
-### 高级特性映射
-
-**1. 动态分区处理**
-
-```sql
--- Spark需要手动处理动态分区
--- Lakehouse使用转换分区自动处理
-CREATE TABLE events (
-    event_time TIMESTAMP,
-    user_id STRING,
-    event_data STRING
-) PARTITIONED BY (
-    days(event_time),        -- 自动按天分区
-    bucket(100, user_id)     -- 自动按用户ID分桶
-);
-```
-
-**2. Schema合并与演进**
-
-```sql
--- Lakehouse原生支持Schema演进
-ALTER TABLE events ADD COLUMN new_field STRING;
-ALTER TABLE events CHANGE COLUMN event_data TYPE JSON;
-```
-
-**3. 复杂数据类型处理**
-
-```sql
--- 完全兼容Spark的复杂类型
-CREATE TABLE user_profiles (
-    user_id BIGINT,
-    tags ARRAY<STRING>,                          -- 标签数组
-    attributes MAP<STRING, STRING>,              -- 属性映射
-    address STRUCT<                              -- 嵌套结构
-        street: STRING,
-        city: STRING,
-        coordinates: STRUCT<lat: DOUBLE, lon: DOUBLE>
-    >,
-    preferences JSON                             -- JSON灵活字段
-);
-```
-
-### 性能优化建议
-
-```sql
--- 针对Spark用户的优化建表模式
-CREATE TABLE optimized_fact_table (
-    -- 业务字段
-    transaction_id BIGINT IDENTITY(1),
-    user_id BIGINT,
-    product_id INT,
-    amount DECIMAL(18, 2),
-    transaction_time TIMESTAMP,
-    
-    -- 生成分区字段（替代Spark的手动分区）

-## Hive用户迁移指南
-
-### 完美的语法兼容性
-
-云器Lakehouse完全兼容Hive的分区语法，同时提供了更强大的功能：
-
-**传统Hive建表**：
-
-```sql
--- Hive风格（完全支持）
-CREATE TABLE IF NOT EXISTS sales_fact (
-    order_id BIGINT,
-    product_id INT,
-    quantity INT,
-    price DECIMAL(10,2)
-) PARTITIONED BY (
-    dt STRING,
-    region STRING
-)
-STORED AS PARQUET
-TBLPROPERTIES ('transactional'='true');
-```
-
-**Lakehouse增强版**：
-
-```sql
--- 相同语法，更强性能
-CREATE TABLE IF NOT EXISTS sales_fact (
-    order_id BIGINT,
-    product_id INT,
-    quantity INT,
-    price DECIMAL(10,2),
-    order_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP  -- 新增：默认值
-) PARTITIONED BY (
-    dt STRING,
-    region STRING
-)
-COMMENT 'Sales fact table with enhanced features'
-PROPERTIES (
-    'data_lifecycle' = '1095',      -- 新增：3年生命周期管理
-    'change_tracking' = 'false'     -- 新增：CDC能力预留
-);
-```
-
-### 分区策略升级
-
-**静态分区到智能分区的进化**：
-
-```sql
--- Hive传统方式：需要手动管理分区
-INSERT OVERWRITE TABLE sales_fact PARTITION(dt='2024-06-20', region='CN')
-SELECT ...;
-
--- Lakehouse智能方式：自动分区管理
-CREATE TABLE sales_fact_smart (
-    order_id BIGINT,
-    order_time TIMESTAMP,
-    region_code STRING,
-    amount DECIMAL(10,2),
-    -- 自动生成分区字段
-    dt STRING GENERATED ALWAYS AS (date_format(order_time, 'yyyy-MM-dd'))
-) PARTITIONED BY (dt, region_code);
-
--- 插入时自动处理分区
-INSERT INTO sales_fact_smart (order_id, order_time, region_code, amount)
-VALUES (1001, CURRENT_TIMESTAMP, 'CN', 99.99);
-```
-
-### 事务表能力增强
-
-```sql
--- Hive事务表限制多，Lakehouse原生支持
-CREATE TABLE transaction_table (
-    id BIGINT PRIMARY KEY,           -- 原生主键支持
-    data STRING,
-    version INT,
-    updated_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP
-) 
-CLUSTERED BY (id) INTO 16 BUCKETS   -- 必需的分桶优化
-PROPERTIES (
-    'data_retention_days' = '7'      -- Time Travel能力
-);
-```
-
-### 性能提升对比
-
-| 操作类型     | Hive (MapReduce) | Lakehouse | 性能提升 |
-| -------- | ---------------- | --------- | ---- |
-| 建表速度     | 秒级               | 毫秒级       | 10x  |
-| 分区裁剪     | 文件级扫描            | 元数据裁剪     | 100x |

-## MaxCompute用户迁移指南
-
-### 语法对照与增强
-
-MaxCompute用户会发现云器Lakehouse的语法非常熟悉，同时功能更加强大：
-
-**MaxCompute建表**：
-
-```sql
--- MaxCompute语法
-CREATE TABLE IF NOT EXISTS sale_detail(
-    shop_name STRING,
-    customer_id STRING,
-    total_price DOUBLE
-)
-PARTITIONED BY (sale_date STRING, region STRING)
-LIFECYCLE 730;
-```
-
-**Lakehouse对应语法**：
-
-```sql
--- 几乎相同的语法，更多功能
-CREATE TABLE IF NOT EXISTS sale_detail(
-    shop_name STRING,
-    customer_id STRING,
-    total_price DOUBLE,
-    -- 新增能力
-    create_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-    row_id BIGINT IDENTITY(1)  -- 自增主键
-)
-PARTITIONED BY (sale_date STRING, region STRING)
-PROPERTIES (
-    'data_lifecycle' = '730',  -- 生命周期（天）
-    'data_retention_days' = '7' -- Time Travel保留期
-);
-```
-
-### 函数兼容性
-
-```sql
--- MaxCompute函数 → Lakehouse函数映射
-CREATE TABLE datetime_example (
-    id INT,
-    -- MaxCompute: GETDATE() → Lakehouse: CURRENT_TIMESTAMP
-    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-    
-    -- 日期函数完全兼容
-    year_part INT GENERATED ALWAYS AS (YEAR(created_at)),
-    month_part INT GENERATED ALWAYS AS (MONTH(created_at)),
-    
-    -- 字符串函数相同
-    user_name STRING,
-    name_length INT GENERATED ALWAYS AS (LENGTH(user_name))
-);
-```
-
-### 资源管理对比
-
-| 特性   | MaxCompute | Lakehouse  | 优势   |
-| ---- | ---------- | ---------- | ---- |
-| 计算资源 | 预付费CU      | 弹性VCLUSTER | 按需付费 |
-| 存储限制 | 项目配额       | 无限扩展       | 更灵活  |
-| 并发控制 | 作业队列       | 动态调度       | 更高效  |
-| 跨地域  | 需要迁移       | 原生支持       | 全球化  |

-## Snowflake用户迁移指南
-
-### 架构理念对比
-
-两者都是云原生数据仓库，但Lakehouse提供了更多的控制权：
-
-**Snowflake风格建表**：
-
-```sql
--- Snowflake
-CREATE OR REPLACE TABLE customer_transactions (
-    transaction_id NUMBER AUTOINCREMENT,
-    customer_id VARCHAR,
-    amount NUMBER(18,2),
-    transaction_date TIMESTAMP_NTZ,
-    status VARCHAR DEFAULT 'PENDING'
-) CLUSTER BY (customer_id);
-```
-
-**Lakehouse增强版**：
-
-```sql
--- Lakehouse：更明确的优化控制
-CREATE TABLE IF NOT EXISTS customer_transactions (
-    transaction_id BIGINT IDENTITY(1),  -- 对应AUTOINCREMENT
-    customer_id VARCHAR(100),
-    amount DECIMAL(18,2),
-    transaction_date TIMESTAMP_NTZ,
-    status VARCHAR(20) DEFAULT 'PENDING',
-    
-    -- 额外优化字段
-    tx_date STRING GENERATED ALWAYS AS (date_format(transaction_date, 'yyyy-MM-dd')),
-    INDEX idx_customer (customer_id) BLOOMFILTER  -- 显式索引
-) 
-PARTITIONED BY (tx_date)  -- 显式分区策略
-CLUSTERED BY (customer_id) INTO 128 BUCKETS  -- 明确分桶数
-COMMENT 'Customer transaction table with explicit optimizations';
-```
-
-### 时间旅行与克隆
-
-```sql
--- Snowflake Time Travel → Lakehouse Time Travel
-CREATE TABLE orders_backup AS
-SELECT * FROM orders;  -- 立即复制
-
--- Lakehouse还支持：
-ALTER TABLE orders SET PROPERTIES ('data_retention_days' = '30');  -- 30天历史
--- 查询历史数据
-SELECT * FROM orders TIMESTAMP AS OF '2024-06-01 00:00:00';
-```
-
-### 性能调优差异
-
-```sql
--- Snowflake：自动优化
--- Lakehouse：提供更多调优选项
-
-CREATE TABLE large_fact_table (
-    -- 列定义
-    fact_id BIGINT,
-    dim1_id INT,
-    dim2_id INT,
-    measure1 DECIMAL(18,4),
-    measure2 DECIMAL(18,4),
-    fact_time TIMESTAMP,
-    
-    -- 性能优化
-    fact_date STRING GENERATED ALWAYS AS (date_format(fact_time, 'yyyy-MM-dd'))
-) 
-PARTITIONED BY (fact_date)
-CLUSTERED BY (dim1_id, dim2_id) 
-    SORTED BY (fact_time DESC)    -- 额外的排序优化
-    INTO 256 BUCKETS              -- 精确控制并行度
-PROPERTIES (
-    'partition.cache.policy.latest.count' = '30'  -- 缓存策略
-);
-```

-## Databricks用户迁移指南
-
-### Delta Lake理念的深度融合
-
-Lakehouse借鉴了Delta Lake的设计理念，提供类似但更简洁的语法：
-
-**Databricks Delta表**：
-
-```python
-# Databricks Python API
-(spark.sql("""
-    CREATE TABLE IF NOT EXISTS events (
-        event_id LONG,
-        event_time TIMESTAMP,
-        user_id STRING,
-        event_type STRING,
-        properties MAP<STRING, STRING>
-    ) USING DELTA
-    PARTITIONED BY (date(event_time))
-    TBLPROPERTIES (
-        'delta.deletedFileRetentionDuration' = '7 days',
-        'delta.optimizeWrite' = 'true'
-    )
-"""))
-```
-
-**Lakehouse原生SQL**：
-
-```sql
--- 纯SQL实现，无需Python包装
-CREATE TABLE IF NOT EXISTS events (
-    event_id BIGINT,
-    event_time TIMESTAMP,
-    user_id STRING,
-    event_type STRING,
-    properties MAP<STRING, STRING>,
-    -- 自动分区字段
-    event_date DATE GENERATED ALWAYS AS (CAST(event_time AS DATE))
-) 
-PARTITIONED BY (event_date)
-PROPERTIES (
-    'data_retention_days' = '7',      -- 对应deletedFileRetentionDuration
-    'data_lifecycle' = '365'          -- 数据生命周期管理
-);
-```
-
-### 流批一体架构
-
-```sql
--- 支持实时写入的表设计
-CREATE TABLE streaming_events (
-    event_id BIGINT PRIMARY KEY,      -- 支持实时去重
-    event_data JSON,
-    received_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-    processed_at TIMESTAMP,
-    
-    -- 分区设计支持流式写入
-    event_hour INT GENERATED ALWAYS AS (hour(received_at)),
-    event_date STRING GENERATED ALWAYS AS (date_format(received_at, 'yyyy-MM-dd'))
-) 
-PARTITIONED BY (event_date, event_hour)
-CLUSTERED BY (event_id) INTO 32 BUCKETS
-PROPERTIES (
-    'change_tracking' = 'false'  -- 为Table Stream预留
-);
-```
-
-### Z-Order优化对应
-
-```sql
--- Databricks: OPTIMIZE table ZORDER BY (col1, col2)
--- Lakehouse: 通过CLUSTERED BY + SORTED BY实现类似效果
-
-CREATE TABLE optimized_table (
-    col1 INT,
-    col2 STRING,
-    col3 DECIMAL(10,2),
-    col4 TIMESTAMP
-)
-CLUSTERED BY (col1, col2)      -- 数据聚集
-SORTED BY (col1, col2)          -- 排序优化
-INTO 64 BUCKETS;
-```
-
-***
-
-## 传统数据库用户迁移指南
-
-### 思维模式转变
-
-从OLTP到OLAP的转变需要调整表设计思路：
-
-**传统OLTP设计**：
-
-```sql
--- MySQL/PostgreSQL/Oracle风格
-CREATE TABLE orders (
-    order_id INT PRIMARY KEY AUTO_INCREMENT,
-    customer_id INT NOT NULL,
-    order_date DATETIME DEFAULT NOW(),
-    status VARCHAR(20) DEFAULT 'NEW',
-    FOREIGN KEY (customer_id) REFERENCES customers(id),
-    INDEX idx_date (order_date),
-    INDEX idx_customer (customer_id)
-);
-```
-
-**Lakehouse OLAP设计**：
-
-```sql
--- 面向分析优化的设计
-CREATE TABLE orders (
-    order_id BIGINT IDENTITY(1),     -- 自增主键
-    customer_id INT NOT NULL,
-    order_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-    status VARCHAR(20) DEFAULT 'NEW',
-    
-    -- 分析优化字段
-    order_year INT GENERATED ALWAYS AS (year(order_date)),
-    order_month INT GENERATED ALWAYS AS (month(order_date)),
-    order_day INT GENERATED ALWAYS AS (day(order_date)),
-    
-    -- 索引定义
-    INDEX bloom_customer (customer_id) BLOOMFILTER,
-    INDEX bloom_status (status) BLOOMFILTER
-) 
-PARTITIONED BY (order_year, order_month)  -- 按月分区
-CLUSTERED BY (customer_id) INTO 256 BUCKETS  -- 客户维度优化
-PROPERTIES (
-    'data_lifecycle' = '2555'  -- 7年数据保留
-);
-```
-
-### 数据类型映射
-
-| 传统数据库               | Lakehouse          | 迁移建议         |
-| ------------------- | ------------------ | ------------ |
-| INT AUTO\_INCREMENT | BIGINT IDENTITY(1) | 使用BIGINT避免溢出 |
-| DATETIME            | TIMESTAMP          | 统一时间类型       |
-| TEXT                | STRING             | 默认16MB，可调整   |
-| ENUM                | VARCHAR + CHECK    | 使用约束替代       |
-| JSON (MySQL)        | JSON               | 原生JSON支持     |
-| SERIAL (PG)         | BIGINT IDENTITY(1) | 完全兼容         |
-
-### 索引策略转换
-
-```sql
--- 传统B-Tree索引 → 列式存储优化
-CREATE TABLE user_activity (
-    user_id BIGINT,
-    activity_time TIMESTAMP,
-    activity_type VARCHAR(50),
-    details JSON,
-    
-    -- 布隆过滤器替代B-Tree（点查询）
-    INDEX bloom_user (user_id) BLOOMFILTER,
-    
-    -- 倒排索引替代全文索引
-    INDEX inv_details (details) INVERTED PROPERTIES ('analyzer' = 'english'),
-    
-    -- 生成列优化时间查询
-    activity_date STRING GENERATED ALWAYS AS (date_format(activity_time, 'yyyy-MM-dd'))
-) 
-PARTITIONED BY (activity_date)  -- 时间分区加速范围查询
-CLUSTERED BY (user_id) INTO 128 BUCKETS;  -- 用户维度聚集
-```
-
-***
-
-## 高级特性详解
-
-### 1. 自增列（IDENTITY）
-
-```sql
--- 完整示例：订单表with自增主键
-CREATE TABLE order_master (
-    order_id BIGINT IDENTITY(1000),  -- 从1000开始
-    order_no VARCHAR(50) NOT NULL,
-    customer_id BIGINT NOT NULL,
-    total_amount DECIMAL(18,2),
-    create_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP
-) COMMENT '订单主表';
-
--- 注意事项：
--- 1. 仅支持BIGINT类型
--- 2. 不保证连续性（高并发下可能跳号）
--- 3. 不支持ALTER TABLE添加
-```
-
-**2. 生成列（GENERATED ALWAYS AS）**
-
-```sql
--- 时间维度自动生成
-CREATE TABLE sales_detail (
-    sale_time TIMESTAMP,
-    product_id INT,
-    quantity INT,
-    unit_price DECIMAL(10,2),
-    
-    -- 自动计算字段
-    total_amount DECIMAL(18,2) GENERATED ALWAYS AS (quantity * unit_price),
-    
-    -- 时间维度展开
-    sale_date STRING GENERATED ALWAYS AS (date_format(sale_time, 'yyyy-MM-dd')),
-    sale_year INT GENERATED ALWAYS AS (year(sale_time)),
-    sale_month INT GENERATED ALWAYS AS (month(sale_time)),
-    sale_week INT GENERATED ALWAYS AS (weekofyear(sale_time)),
-    sale_hour INT GENERATED ALWAYS AS (hour(sale_time))
-) 
-PARTITIONED BY (sale_date)  -- 可以用生成列作为分区
-COMMENT '销售明细表with自动计算字段';
-```
-
-**生成列使用限制**：
-
-* 生成列不能用于 `CLUSTERED BY` 或 `SORTED BY`
-* 主键表不能使用生成列作为分区键
-* 只支持确定性函数，不支持 `CURRENT_DATE`、`RANDOM` 等非确定性函数
-
-### 3. 默认值（DEFAULT）
-
-```sql
--- 审计表设计
-CREATE TABLE audit_log (
-    log_id BIGINT IDENTITY(1),
-    table_name VARCHAR(100) NOT NULL,
-    operation VARCHAR(20) NOT NULL,
-    user_id VARCHAR(50) DEFAULT CURRENT_USER(),  -- 当前用户
-    operation_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP,  -- 当前时间
-    client_ip VARCHAR(50) DEFAULT '0.0.0.0',
-    status VARCHAR(20) DEFAULT 'SUCCESS',
-    details JSON
-) 
-PARTITIONED BY (date_format(operation_time, 'yyyy-MM-dd'))
-COMMENT '统一审计日志表';
-```
-
-### 4. 主键与唯一约束
-
-```sql
--- CDC场景的主键表设计
-CREATE TABLE customer_snapshot (
-    customer_id BIGINT,
-    snapshot_date DATE,
-    customer_name VARCHAR(200),
-    customer_level VARCHAR(20),
-    total_purchase DECIMAL(18,2),
-    last_update TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-    
-    -- 复合主键
-    PRIMARY KEY (customer_id, snapshot_date)
-) 
-PARTITIONED BY (snapshot_date)
-CLUSTERED BY (customer_id, snapshot_date) 
-SORTED BY (customer_id, snapshot_date) INTO 64 BUCKETS  -- 注意：主键表必须使用ASC排序
-COMMENT '客户快照表for CDC';
-```
-
-**主键表的重要限制**：
-
-* 主键列必须包含在 `CLUSTERED BY` 和 `SORTED BY` 中
-* `SORTED BY` 必须使用升序（ASC），不能使用降序（DESC）
-* 分区列必须是主键的子集
-* 如果使用生成列，不能将其作为主键表的分区列
-
-### 5. 复杂索引策略
-
-```sql
--- 多维度查询优化表
-CREATE TABLE product_search (
-    product_id BIGINT PRIMARY KEY,
-    product_name VARCHAR(500),
-    description STRING,
-    category_path VARCHAR(200),
-    brand VARCHAR(100),
-    price DECIMAL(10,2),
-    tags ARRAY<STRING>,
-    attributes MAP<STRING, STRING>,
-    
-    -- 多种索引组合（注意：索引名必须全局唯一）
-    INDEX bloom_prod_brand (brand) BLOOMFILTER,  -- 品牌快速过滤
-    INDEX bloom_prod_category (category_path) BLOOMFILTER,  -- 类目过滤
-    INDEX inv_prod_name (product_name) INVERTED PROPERTIES ('analyzer' = 'chinese'),  -- 商品名搜索
-    INDEX inv_prod_desc (description) INVERTED PROPERTIES ('analyzer' = 'chinese')  -- 描述搜索
-)
-CLUSTERED BY (product_id) SORTED BY (product_id) INTO 128 BUCKETS  -- 主键表限制
-COMMENT '商品搜索优化表';
-```
-
-**索引命名最佳实践**：
-
-* 索引名必须在整个数据库中唯一
-* 建议使用 `表名_列名` 或 `idx_表名_列名` 格式
-* 避免使用过于通用的名称如 `idx_id`
-
-### 6. 向量索引（VECTOR）
-
-```sql
--- 向量搜索场景表设计
-CREATE TABLE embeddings_search (
-    doc_id BIGINT PRIMARY KEY,
-    content STRING,
-    embedding VECTOR(512),  -- 512维向量，默认float类型
-    vec_small VECTOR(128),  -- 128维向量
-    vec_int VECTOR(int, 256),  -- 指定int类型的256维向量
-    
-    -- 向量索引
-    INDEX vec_idx (embedding) USING VECTOR PROPERTIES (
-        'scalar.type' = 'f32',
-        'distance.function' = 'cosine_distance',  -- 余弦距离
-        'm' = '16',  -- HNSW算法参数
-        'ef.construction' = '200'
-    )
-)
-CLUSTERED BY (doc_id) SORTED BY (doc_id) INTO 64 BUCKETS
-COMMENT '向量搜索优化表';
-```
-
-**向量类型使用限制**：
-
-* 不支持在ORDER BY或GROUP BY中使用
-* 支持的元素类型：tinyint、int、float（默认）
-* 可与数组类型相互转换
-
-***
-
-## 分区策略最佳实践
-
-### 1. 时间分区设计
-
-```sql
--- 多粒度时间分区
-CREATE TABLE event_log (
-    event_id BIGINT,
-    event_time TIMESTAMP,
-    event_type VARCHAR(50),
-    event_data JSON,
-    
-    -- 多层分区字段生成
-    event_date STRING GENERATED ALWAYS AS (date_format(event_time, 'yyyy-MM-dd')),
-    event_hour INT GENERATED ALWAYS AS (hour(event_time))
-) 
-PARTITIONED BY (event_date, event_hour)  -- 双层分区
-COMMENT '事件日志表with小时级分区';
-
--- 转换分区函数示例
-CREATE TABLE metric_data (
-    metric_time TIMESTAMP,
-    metric_name VARCHAR(100),
-    metric_value DOUBLE
-) 
-PARTITIONED BY (
-    days(metric_time)  -- 按天数分区（从1970-01-01开始）
-);
-```
-
-### 2. 业务维度分区
-
-```sql
--- 多维度组合分区
-CREATE TABLE transaction_fact (
-    tx_id BIGINT IDENTITY(1),
-    tx_time TIMESTAMP,
-    region_code VARCHAR(10),
-    channel_code VARCHAR(10),
-    amount DECIMAL(18,2),
-    
-    tx_date STRING GENERATED ALWAYS AS (date_format(tx_time, 'yyyy-MM-dd'))
-) 
-PARTITIONED BY (tx_date, region_code, channel_code)  -- 三维分区
-CLUSTERED BY (tx_id) INTO 256 BUCKETS
-COMMENT '交易事实表with多维分区';
-```
-
-### 3. 分区数量控制
-
-```sql
--- 合理控制分区粒度
-CREATE TABLE log_archive (
-    log_time TIMESTAMP,
-    log_level VARCHAR(10),
-    log_content STRING,
-    
-    -- 按月分区，避免过多分区
-    log_month STRING GENERATED ALWAYS AS (date_format(log_time, 'yyyy-MM'))
-) 
-PARTITIONED BY (log_month)
-PROPERTIES (
-    'data_lifecycle' = '1095'  -- 3年后自动清理
-);
-```
-
-***
-
-## 分桶优化指南
-
-### 1. 分桶数量选择
-
-```sql
--- 分桶数量计算公式：总数据量 / 128MB~1GB
-
--- 小表（<10GB）：少量分桶
-CREATE TABLE small_dim (
-    dim_id INT,
-    dim_name VARCHAR(100)
-) CLUSTERED BY (dim_id) INTO 8 BUCKETS;
-
--- 中表（10GB~1TB）：适度分桶

-)
-COMMENT '销售事实表';
-```
-
-### 3. 宽表模式
-
-```sql
--- 宽表设计（星型模式去规范化）
-CREATE TABLE user_behavior_wide (
-    -- 用户维度
-    user_id BIGINT,
-    user_name VARCHAR(100),
-    user_level VARCHAR(20),

-* **建议检查**：大批量导入前统计分区数量
-
-### 1.6 列映射和类型匹配
-
-* **显式指定**：建议明确指定目标列名
-* **类型匹配**：确保数据类型精确对应
-* **NULL处理**：未指定列将填入NULL值
-
-## 2. UPDATE语句规范
-
-### 2.1 基本语法
-
-```sql
-UPDATE target_table 
-SET column_name1 = new_value1 [, column_name2 = new_value2, ...] 
-[ WHERE condition ] 
-[ORDER BY ...] 
-[LIMIT row_count]
-```
-
-### 2.2 WHERE条件要求
-
-* **必要性**：强烈建议使用WHERE条件限制更新范围
-* **精确性**：使用精确条件避免误操作
-* **复杂查询**：支持子查询和表达式
-

-
-* **分批处理**：使用ORDER BY + LIMIT实现分批更新
-* **确定性**：ORDER BY保证更新顺序一致性
-* **性能控制**：LIMIT控制单次更新行数
-
-### 2.4 安全操作建议
-
-* **测试验证**：生产环境前在测试环境验证
-* **数据备份**：重要更新前创建备份
-* **回滚准备**：准备数据恢复方案
-
-## 3. DELETE语句规范
-
-### 3.1 基本语法
-
-```sql
-DELETE FROM table_name WHERE condition;
-```
-
-### 3.2 安全要求
-
-* **WHERE条件**：避免省略WHERE导致全表删除
-* **条件验证**：删除前验证条件的准确性
-* **备份保护**：重要数据删除前备份
-
-### 3.3 性能优化
-
-* **索引利用**：WHERE条件充分利用索引
-* **分区过滤**：分区表使用分区列进行过滤
-* **批量删除**：大批量删除考虑分批执行
-
-## 4. MERGE INTO语句规范
-
-### 4.1 基本语法
-
-```sql
-MERGE INTO target_table USING source_table ON merge_condition 
-{ WHEN MATCHED [AND matched_condition] THEN matched_action |
-  WHEN NOT MATCHED [AND not_matched_condition] THEN not_matched_action } ...
-```
-
-### 4.2 语句顺序要求
-
-**WHEN MATCHED 必须在 WHEN NOT MATCHED 之前**
-
-```sql
--- ✅ 正确顺序
-MERGE INTO target USING source ON target.key = source.key 
-WHEN MATCHED THEN UPDATE SET target.col1 = source.col1
-WHEN NOT MATCHED THEN INSERT (col1, col2) VALUES (source.col1, source.col2);
-```
-
-### 4.3 匹配条件设计
-
-* **唯一性**：确保ON条件产生一对一匹配
-* **确定性**：避免源表多行匹配目标表同一行
-* **过滤支持**：支持AND条件进行额外过滤
-
-### 4.4 操作类型
-
-* **MATCHED操作**：UPDATE SET 或 DELETE
-* **NOT MATCHED操作**：INSERT语句
-* **条件执行**：按指定顺序执行多个WHEN子句
-
-## 5. TRUNCATE语句规范
-
-### 5.1 基本语法
-
-```sql
-TRUNCATE TABLE [IF EXISTS] table_name;
-```
-
-### 5.2 操作特点
-
-* **数据清空**：删除所有记录但保留表结构
-* **性能优势**：比DELETE FROM更高效
-* **不可恢复**：操作后数据无法直接恢复
-
-### 5.3 使用建议
-
-* **IF EXISTS**：使用IF EXISTS子句避免错误
-* **权限检查**：确保具有相应操作权限
-* **备份保护**：重要表操作前备份数据
-
-## 6. Dynamic Table DML规范
-
-### 6.1 参数配置

-```
-
-### 6.2 支持的操作
-
-```sql
--- ✅ 完全支持
-INSERT INTO dynamic_table VALUES (1, 'data', 100);
-INSERT OVERWRITE dynamic_table SELECT * FROM source;
-DELETE FROM dynamic_table WHERE condition;
-TRUNCATE TABLE dynamic_table;
-```
-
-### 6.3 操作限制
-
-* **UPDATE限制**：UPDATE 操作存在技术限制，建议使用 DELETE + INSERT 替代
-* **刷新影响**：DML操作可能导致下次刷新转为全量模式
-* **性能考虑**：全量刷新比增量刷新开销更大
-
-## 7. 性能优化策略
-
-### 7.1 分区设计原则
-
-* **分区大小**：遵循业界标准，避免过小分区影响查询性能
-* **分区数量**：控制分区总数，平衡存储和查询效率

-
-### 7.2 分桶配置策略
-
-* **分桶列选择**：选择高基数、分布均匀的列
-* **分桶数量**：基于数据量和查询模式确定合理数量
-* **排序优化**：SORTED BY选择频繁查询的列
-
-### 7.3 索引优化
-
-* **BLOOM FILTER 索引**：适用于等值查询和高基数列
-* **INVERTED 索引**：适用于全文搜索，需指定分析器
-* **VECTOR 索引**：适用于向量相似度搜索场景
-
-### 7.4 小文件管理
-
-```sql
--- 自动合并配置
-SET cz.sql.compaction.after.commit = true;
-
--- 手动合并命令
-OPTIMIZE table_name [WHERE predicate] [OPTIONS ('key' = 'value')];
-```
-
-## 8. 数据类型转换
-
-### 8.1 转换方法
-
-```sql
--- CAST函数
-CAST(expression AS type)
-
--- 转换运算符
-expression::type
-
--- TYPE函数（转换失败返回NULL）
-TYPE(expr)
-```
-
-### 8.2 转换规则
-
-* **数值扩展**：支持精度扩大的转换
-* **字符串转换**：支持长度增加的转换
-* **日期转换**：字符串与日期类型双向转换

-
-## 12. 最佳实践
-
-### 12.1 数据类型使用规范
-
-| 数据类型      | 前缀要求 | 语法示例                             |
-| --------- | ---- | -------------------------------- |
-| DATE      | 必须   | `date'2023-12-25'`               |
-| TIMESTAMP | 必须   | `timestamp'2023-12-25 15:30:45'` |
-| JSON      | 必须   | `json'{"key": "value"}'`         |
-| BINARY    | 必须   | `X'48656C6C6F'`                  |
-| BIGINT    | 可选   | `1` 或 `1l`                       |

-| DOUBLE    | 可选   | `3.14` 或 `3.14d`                 |
-
-### 11.2 INSERT语句模板
-
-```sql
--- 推荐的大量数据导入
-INSERT INTO target_table 
-SELECT col1, col2, col3 FROM source_table WHERE condition;
-
--- 类型安全的VALUES插入
-INSERT INTO table_name (
-    bigint_col, decimal_col, date_col, 
-    timestamp_col, json_col, binary_col
-) VALUES (
-    1, 99.99, date'2023-12-25',
-    timestamp'2023-12-25 15:30:45',
-    json'{"key": "value"}', X'48656C6C6F'
-);
-```
-
-### 11.3 MERGE语句模板
-
-```sql
-MERGE INTO target_table AS target 
-USING source_table AS source 
-ON target.key_column = source.key_column 
-WHEN MATCHED THEN 
-    UPDATE SET target.col1 = source.col1, target.col2 = source.col2
-WHEN NOT MATCHED THEN 
-    INSERT (key_column, col1, col2) 
-    VALUES (source.key_column, source.col1, source.col2);
-```
-
-### 11.4 Dynamic Table DML模板
-
-```sql
--- 会话配置
-SET cz.sql.dt.allow.dml = true;
-
--- 支持的操作
-INSERT INTO dynamic_table VALUES (1, 'data', 100);
-DELETE FROM dynamic_table WHERE condition;
-
--- 替代UPDATE的方案
-DELETE FROM dynamic_table WHERE key_column = target_value;
-INSERT INTO dynamic_table VALUES (new_key, new_col1, new_col2);
-```
-
-### 11.5 安全操作原则
-
-1. **测试先行**：生产环境操作前完成测试验证
-2. **备份保护**：重要数据操作前创建备份
-3. **权限最小化**：使用最小必要权限执行操作
-4. **条件精确**：WHERE条件精确限制操作范围
-5. **监控审计**：记录重要DML操作的执行日志
-
-### 11.6 性能优化原则
-
-1. **批量优先**：优先使用批量操作提高效率
-2. **索引利用**：充分利用索引加速查询和DML
-3. **分区过滤**：利用分区剪枝减少数据扫描
-4. **资源管理**：合理配置计算资源和并发度
-5. **文件管理**：定期执行小文件合并优化
-
-### 12.6 版本控制和数据恢复原则
-
-1. **数据保留设置**：根据业务需求合理设置数据保留周期
-2. **变更跟踪启用**：对重要表启用变更跟踪便于数据审计
-3. **定期检查历史**：定期查看表操作历史发现异常操作
-4. **恢复操作验证**：数据恢复前在测试环境验证恢复效果
-5. **Time Travel 查询**：使用相对时间查询避免时区问题
-
-### 12.7 Table Stream 使用原则
-
-```sql
--- 推荐的Stream创建和使用模式
--- 1. 启用变更跟踪
-ALTER TABLE source_table SET PROPERTIES('change_tracking' = 'true');
-
--- 2. 创建Stream
-CREATE TABLE STREAM change_stream 
-ON TABLE source_table
-WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
-
--- 3. 查询变更数据
-SELECT * FROM change_stream WHERE cz_stream_action IN ('INSERT', 'UPDATE', 'DELETE');
-```
-
-### 12.8 历史版本和数据恢复模板
-
-```sql
--- 查看表历史
-DESCRIBE HISTORY table_name;
-
--- Time Travel查询
-SELECT * FROM table_name 
-TIMESTAMP AS OF (CURRENT_TIMESTAMP() - INTERVAL '1' HOUR);
-
--- 数据恢复
-RESTORE TABLE table_name TO TIMESTAMP AS OF '20<https://j4vjdq19vx.x.topthink.com/#>25-06-18 10:30:45';
-
--- 恢复删除的表
-UNDROP TABLE table_name;
-
--- 启用变更跟踪
-ALTER TABLE table_name SET PROPERTIES('change_tracking' = 'true');
-
--- 创建Table Stream
-CREATE TABLE STREAM stream_name 
-ON TABLE table_name
-WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
-
--- 设置数据保留周期
-ALTER TABLE table_name SET PROPERTIES('data_retention_days' = '7');
-```

-
----
-
-## JOIN类型与语法
-
-### 完整的JOIN类型支持
-
-云器Lakehouse支持完整的SQL JOIN标准，提供7种JOIN类型：
-
-| JOIN类型 | 功能描述 | 典型应用场景 |
-|----------|----------|-------------|
-| **INNER JOIN** | 返回两表匹配记录 | 标准业务关联查询 |
-| **LEFT [OUTER] JOIN** | 保留左表全部记录 | 主表数据完整性保证 |
-| **RIGHT [OUTER] JOIN** | 保留右表全部记录 | 维度表完整性展示 |
-| **FULL [OUTER] JOIN** | 保留两表全部记录 | 完整数据审计分析 |
-| **SEMI JOIN** | 返回左表中存在匹配的记录 | 数据存在性验证 |
-| **ANTI JOIN** | 返回左表中不存在匹配的记录 | 数据差异化分析 |
-| **CROSS JOIN** | 返回两表笛卡尔积 | 数据组合生成 |
-
-### 基础JOIN语法
-
-```sql
--- 标准INNER JOIN
-SELECT e.emp_name, d.dept_name
-FROM employees e
-INNER JOIN departments d ON e.dept_id = d.dept_id;
-
--- LEFT JOIN保证左表完整性
-SELECT e.emp_name, d.dept_name
-FROM employees e
-LEFT JOIN departments d ON e.dept_id = d.dept_id;
-
--- SEMI JOIN进行存在性检查
-SELECT e.emp_name, e.salary
-FROM employees e
-SEMI JOIN departments d ON e.dept_id = d.dept_id;
-
--- ANTI JOIN识别孤立数据
-SELECT e.emp_name, e.dept_id
-FROM employees e
-ANTI JOIN departments d ON e.dept_id = d.dept_id;
-```
-
----
-
-## 性能优化策略
-
-### MAPJOIN广播优化
-
-MAPJOIN 是云器 Lakehouse 的核心优化特性，通过将小表广播到所有计算节点，显著提升JOIN性能。
-
-**优化原理**：
-- 消除昂贵的 Shuffle 操作
-- 缓解数据倾斜问题
-- 提升查询执行速度
-
-```sql
--- 单表广播优化
-SELECT /*+ MAPJOIN(departments) */ 
-    e.emp_name, d.dept_name, d.budget
-FROM employees e
-JOIN departments d ON e.dept_id = d.dept_id;
-
--- 多表广播优化
-SELECT /*+ MAPJOIN(employees, departments) */
-    o.order_id, e.emp_name, d.dept_name
-FROM orders o
-JOIN employees e ON o.emp_id = e.emp_id
-JOIN departments d ON e.dept_id = d.dept_id;
-```
-
-**使用建议**：
-- 小表大小建议控制在 1GB 以内
-- 适用于维度表与事实表的关联
-- 优先考虑小表广播，而非大表 JOIN 大表
-
-### SORTMERGEJOIN排序合并优化
-
-适用于大表与大表的 JOIN 场景，特别是数据已按 JOIN 键排序的情况。
-
-```sql
--- 大表JOIN优化
-SELECT /*+ SORTMERGEJOIN(table1, table2) */
-    t1.customer_id, t2.order_amount
-FROM large_customer_table t1
-JOIN large_order_table t2 ON t1.customer_id = t2.customer_id;
-```
-
-### 查询结构优化
-
-遵循“过滤-连接-聚合”的最佳实践模式：
-
-```sql
--- 推荐的查询结构
-WITH filtered_facts AS (
-    SELECT fact_id, dimension_id, amount, date_key
-    FROM fact_table
-    WHERE date_key >= '20240101'          -- 先过滤
-      AND amount > 1000
-),
-enriched_data AS (
-    SELECT /*+ MAPJOIN(dim_table) */
-        f.fact_id, f.amount, d.category
-    FROM filtered_facts f
-    JOIN dim_table d ON f.dimension_id = d.dimension_id  -- 后连接
-)
-SELECT 
-    category,
-    COUNT(*) as record_count,
-    SUM(amount) as total_amount                          -- 最后聚合
-FROM enriched_data
-GROUP BY category;
-```
-
----
-
-## Spark用户迁移指南
-
-### 直接迁移的技能
-
-Spark用户可以无缝使用以下功能：
-
-```sql
--- DataFrame广播JOIN → MAPJOIN提示
-SELECT /*+ MAPJOIN(small_table) */
-    l.order_id, s.product_name
-FROM large_orders l
-JOIN small_products s ON l.product_id = s.product_id;
-
--- 窗口函数完全兼容
-SELECT 
-    emp_name,
-    salary,
-    ROW_NUMBER() OVER (PARTITION BY dept_id ORDER BY salary DESC) as rank
-FROM employees;
-
--- 复杂数据类型处理
-SELECT 
-    user_id,
-    event_array[0] as first_event,           -- 数组索引从0开始
-    size(event_array) as event_count,
-    explode(event_array) as individual_event -- 直接使用，无需LATERAL VIEW
-FROM user_events;
-```
-
-### 语法调整要点
-
-**1. 数组展开语法简化**
-
-```sql
--- Spark语法（不支持）
-SELECT user_id, tag
-FROM users LATERAL VIEW explode(tags) t AS tag;
-
--- Lakehouse语法
-SELECT user_id, explode(tags) as tag
-FROM users;
-```
-
-**2. 结构体操作保持一致**
-
-```sql
--- Spark兼容的结构体操作
-WITH customer_profiles AS (
-    SELECT 
-        customer_id,
-        named_struct(
-            'name', customer_name,
-            'contact', named_struct('email', email, 'phone', phone)
-        ) as profile
-    FROM customers
-)
-SELECT 
-    customer_id,
-    profile.name as customer_name,
-    profile.contact.email as email
-FROM customer_profiles;
-```
-
-### 数据倾斜处理策略
-
-```sql
--- 盐值JOIN解决数据倾斜
-WITH salted_large AS (
-    SELECT *, 
-           CONCAT(join_key, '_', ABS(HASH(join_key) % 10)) as salted_key
-    FROM large_table
-),
-salted_small AS (
-    SELECT *, 
-           CONCAT(join_key, '_', sequence) as salted_key
-    FROM small_table 
-    CROSS JOIN (SELECT EXPLODE(SEQUENCE(0, 9)) as sequence)
-)
-SELECT l.data, s.info
-FROM salted_large l
-JOIN salted_small s ON l.salted_key = s.salted_key;
-```
-
----
-
-## Hive用户迁移指南
-
-### 概念延续与性能升级
-
-Hive用户熟悉的分区表和批处理概念在Lakehouse中得到保留和增强：
-
-```sql
--- 分区裁剪概念保持一致
-SELECT /*+ MAPJOIN(dim_table) */
-    fact.order_id, dim.product_name
-FROM fact_orders fact
-JOIN dim_products dim ON fact.product_id = dim.product_id
-WHERE fact.dt = '2024-06-01';           -- 分区字段过滤
-```
-
-### MapReduce到列式计算的跃升
-
-```sql
--- Hive多阶段Job → Lakehouse一体化查询
-WITH order_aggregation AS (
-    SELECT 
-        customer_id,
-        SUM(amount) as total_amount,
-        COUNT(*) as order_count
-    FROM orders 
-    WHERE order_date >= '2024-01-01'
-    GROUP BY customer_id
-)
-SELECT /*+ MAPJOIN(customers) */
-    c.customer_name,
-    a.total_amount,
-    a.order_count
-FROM order_aggregation a
-JOIN customers c ON a.customer_id = c.customer_id
-WHERE a.total_amount > 10000;
-```
-
-### MAPJOIN功能增强
-
-```sql
--- Hive手动控制 → Lakehouse智能优化
-SELECT /*+ MAPJOIN(employees, departments) */  -- 支持多表广播
-    o.order_id, e.emp_name, d.dept_name
-FROM orders o
-JOIN employees e ON o.emp_id = e.emp_id
-JOIN departments d ON e.dept_id = d.dept_id;
-```
-
----
-
-## MaxCompute用户迁移指南
-
-### 语法兼容性
-
-MaxCompute用户可以直接使用熟悉的语法：
-
-```sql
--- MAPJOIN语法直接兼容
-SELECT /*+ MAPJOIN(small_table) */
-    large.order_id, small.product_name
-FROM large_orders large
-JOIN small_products small ON large.product_id = small.product_id;
-
--- 分区查询方式保持一致
-SELECT * FROM orders 
-WHERE order_date = '2024-06-01'
-  AND status = 'completed';
-```
-
-### 函数迁移映射
-
-```sql
--- 时间函数对应关系
-SELECT 
-    order_id,
-    CURRENT_TIMESTAMP() as process_time,        -- MaxCompute: GETDATE()
-    DATE_FORMAT(order_date, 'yyyy-MM') as month -- 语法兼容
-FROM orders;
-```
-
-### SEMI JOIN优化
-
-```sql
--- EXISTS查询 → SEMI JOIN性能优化
-SELECT a.customer_id, a.customer_name
-FROM customers a
-SEMI JOIN orders b ON a.customer_id = b.customer_id;
-```
-
----
-
-## Snowflake用户迁移指南
-
-### 云原生特性对应
-
-```sql
--- 自动优化 → 显式优化控制
-SELECT /*+ MAPJOIN(customer_dim, product_dim) */
-    cd.customer_name, pd.product_name, sf.sales_amount
-FROM sales_fact sf
-JOIN customer_dim cd ON sf.customer_id = cd.customer_id
-JOIN product_dim pd ON sf.product_id = pd.product_id
-WHERE sf.sale_date >= '2024-06-01';
-```
-
-### 资源管理对比
-
-- **Snowflake WAREHOUSE** → **Lakehouse VCLUSTER**
-- **自动扩缩容** → **弹性计算资源**
-- **按需付费** → **按使用量计费**
-
-### 历史数据查询
-
-<= '2024-06-01 23:59:59';
-```
-
----
-
-## 传统数据库用户迁移指南
-
-### 思维模式转换
-
-**从OLTP到OLAP的架构升级**
-
-```sql
--- OLTP思维：单条记录查询
--- 转换为
--- OLAP思维：批量分析查询
-
-SELECT /*+ MAPJOIN(customers) */
-    c.customer_segment,
-    COUNT(*) as order_count,
-    AVG(o.order_amount) as avg_amount,
-    SUM(o.order_amount) as total_amount
-FROM customers c
-JOIN orders o ON c.customer_id = o.customer_id
-WHERE o.order_date >
-
-### 索引策略调整
-
-```sql
--- 传统索引 → 列式存储 + 布隆过滤器
-CREATE BLOOMFILTER INDEX idx_customer_bloom 
-ON TABLE orders(customer_id);
-
--- 查询自动应用优化
-SELECT /*+ MAPJOIN(customers) */
-    c.customer_name, COUNT(o.order_id) as order_count
-FROM customers c
-JOIN orders o ON c.customer_id = o.customer_id
-GROUP BY c.customer_name;
-```
-
-### 事务处理转换
-
-```sql
--- 传统事务 → 批量MERGE操作
-MERGE INTO customers c
-USING (
-    SELECT customer_id
-    FROM order_summary 
-    WHERE total_amount > 50000
-) high_value ON c.customer_id = high_value.customer_id
-WHEN MATCHED THEN UPDATE SET status = 'premium';
-```
-
----
-
-## JOIN条件与语法规范
-
-### 支持的条件语法
-
-```sql
--- ON条件表达式
-SELECT * FROM table1 t1
-JOIN table2 t2 ON t1.id = t2.id;
-
--- USING简化语法
-SELECT * FROM table1 t1
-JOIN table2 t2 USING (id);
-
--- 复合条件
-SELECT * FROM orders o
-JOIN employees e ON o.emp_id = e.emp_id 
-                 AND o.order_date >= e.hire_date;
-```
-
-### 语法限制与替代方案
-
-**JOIN 条件中避免使用子查询**
-
-```sql
--- 不推荐的写法
-SELECT e.emp_name
-FROM employees e
-JOIN departments d ON e.dept_id = (
-    SELECT dept_id FROM departments WHERE dept_name = 'Engineering'
-);
-
--- 推荐的替代方案
-SELECT e.emp_name
-FROM employees e
-JOIN departments d ON e.dept_id = d.dept_id
-WHERE d.dept_name = 'Engineering';
-
--- 或使用CTE
-WITH target_dept AS (
-    SELECT dept_id FROM departments WHERE dept_name = 'Engineering'
-)
-SELECT e.emp_name
-FROM employees e
-JOIN target_dept t ON e.dept_id = t.dept_id;
-```
-
----
-
-## 数据类型与NULL值处理
-
-### NULL值显示特性
-
-云器Lakehouse中不同数据类型的NULL值具有特定的显示格式：
-
-<- STRING类型NULL正常显示
-|          | nan     | HR        | <- 数值类型NULL显示为"nan"
-+----------+---------+-----------+
-*/
-```
-
-**显示规律**：
-- **字符类型**（STRING、VARCHAR）：NULL显示为空
-- **数值类型**（INT、DOUBLE、DECIMAL）：NULL显示为"nan"
-- **时间类型**（DATE、TIMESTAMP）：NULL显示为"NaT"
-- **逻辑判断**：IS NULL和IS NOT NULL在所有类型上正常工作
-
-### NULL值安全处理
-
-```sql
--- 安全的NULL值处理
-SELECT 
-    emp_name,
-    CASE 
-        WHEN salary IS NULL OR CAST(salary AS STRING) = 'nan' 
-        THEN 0.0 
-        ELSE salary 
-    END as safe_salary,
-    COALESCE(dept_name, 'Unknown Department') as safe_dept_name
-FROM employees e
-LEFT JOIN departments d ON e.dept_id = d.dept_id;
-```
-
----
-
-## 复杂JOIN场景
-
-### 多表关联分析
-
-```sql
--- 典型的维度建模查询
-SELECT /*+ MAPJOIN(dim_customer, dim_product, dim_date) */
-    dd.year,
-    dd.quarter,
-    dc.customer_tier,
-    dp.product_line,
-    COUNT(*) as transaction_count,
-    SUM(ft.amount) as total_revenue,
-    AVG(ft.amount) as avg_transaction_value
-FROM fact_transactions ft
-JOIN dim_customer dc ON ft.customer_id = dc.customer_id
-JOIN dim_product dp ON ft.product_id = dp.product_id  
-JOIN dim_date dd ON ft.date_id = dd.date_id
-WHERE dd.year >
-
-### 层次化数据处理
-
-```sql
--- 组织架构多级查询
-WITH employee_hierarchy AS (
-    -- 第一级：高级管理层
-    SELECT employee_id, employee_name, 1 as level
-    FROM employees WHERE manager_id IS NULL
-    
-    UNION ALL
-    
-    -- 第二级：中层管理
-    SELECT e.employee_id, e.employee_name, 2 as level
-    FROM employees e
-    JOIN employees m ON e.manager_id = m.employee_id
-    WHERE m.manager_id IS NULL
-    
-    UNION ALL
-    
-    -- 第三级：基层员工
-    SELECT e.employee_id, e.employee_name, 3 as level
-    FROM employees e
-    JOIN employees m1 ON e.manager_id = m1.employee_id
-    JOIN employees m2 ON m1.manager_id = m2.employee_id
-    WHERE m2.manager_id IS NULL
-)
-SELECT level, COUNT(*) as employee_count
-FROM employee_hierarchy
-GROUP BY level
-ORDER BY level;
-```
-
-### 时间序列JOIN
-
-```sql
--- 时间窗口关联分析
-SELECT o.order_id, l.line_item_id, o.order_date, l.ship_date
-FROM orders o
-JOIN line_items l ON o.order_id = l.order_id
-                  AND o.order_date BETWEEN l.ship_date - INTERVAL '5' DAY 
-                                       AND l.ship_date + INTERVAL '5' DAY
-WHERE o.order_date >= '2024-01-01';
-```
-
----
-
-## 性能调优实践
-
-### 查询优化检查清单
-
-#### 1. JOIN策略选择
-
-```sql
--- 小表 × 大表：MAPJOIN优先
-SELECT /*+ MAPJOIN(dim_table) */
-    fact.*, dim.dimension_name
-FROM fact_table fact
-JOIN dim_table dim ON fact.dim_id = dim.dim_id;
-
--- 大表 × 大表：SORTMERGEJOIN
-SELECT /*+ SORTMERGEJOIN(table1, table2) */
-    t1.*, t2.*
-FROM large_table1 t1
-JOIN large_table2 t2 ON t1.join_key = t2.join_key;
-```
-
-#### 2. 谓词下推优化
-
-```sql
--- 将过滤条件前置
-WITH filtered_base AS (
-    SELECT customer_id, order_id, amount
-    FROM orders
-    WHERE order_date >= '2024-01-01'      -- 过滤前置
-      AND status = 'completed'
-)
-SELECT /*+ MAPJOIN(customers) */
-    c.customer_name, f.amount
-FROM filtered_base f
-JOIN customers c ON f.customer_id = c.customer_id;
-```
-
-#### 3. 列裁剪策略
-
-```sql
--- 明确指定所需列
-SELECT customer_id, customer_name, order_count
-FROM customer_summary
-WHERE registration_date >= '2024-01-01';
-
--- 使用EXCEPT排除不必要的列
-SELECT * EXCEPT(internal_notes, created_by, updated_by)
-FROM customer_details;
-```
-
-### 分页查询策略
-
-#### 基于游标的高效分页
-
-```sql
--- 推荐的分页方式
-SELECT customer_id, order_id, order_date, amount
-FROM orders 
-WHERE customer_id > :last_customer_id  -- 游标位置
-   OR (customer_id = :last_customer_id AND order_id > :last_order_id)
-ORDER BY customer_id, order_id
-LIMIT 1000;
-```
-
-#### 范围分区分页
-
-```sql
--- 基于业务逻辑的分区处理
-SELECT * FROM orders 
-WHERE order_date >= '2024-06-01'
-  AND order_date < '2024-06-02'  -- 按天分批处理
-ORDER BY order_id;
-```
-
----
-
-## 最佳实践总结
-
-### 通用优化原则
-
-1. **小表广播优先**：维度表与事实表关联首选MAPJOIN
-2. **过滤条件前置**：在JOIN之前完成数据过滤
-3. **选择精确JOIN类型**：根据业务需求选择最合适的JOIN类型
-4. **避免深度分页**：使用游标分页替代OFFSET分页
-5. **监控执行计划**：关注查询性能和资源使用

-## 迁移用户指导
-
-如果您习惯了Spark、MySQL、PostgreSQL或其他数据库系统，本节将帮助您快速适应云器Lakehouse并避免常见错误。我们理解切换到新系统的挑战，因此准备了这份详细的对比指南。
-
-### 🔄 **如果您习惯了Spark SQL**
-
-#### ✅ **可以直接复用的技能**
-
-```sql
--- 以下Spark SQL代码可以直接在Lakehouse中运行
-SELECT customer_id, COUNT(*), SUM(amount)
-FROM orders 
-WHERE order_date >= '2024-01-01'
-GROUP BY customer_id
-HAVING COUNT(*) > 5;
-
--- 窗口函数完全兼容
-SELECT 
-    employee_id,
-    salary,
-    ROW_NUMBER() OVER (PARTITION BY department ORDER BY salary DESC) as rank
-FROM employees;
-```
-
-#### ⚠️ **需要调整的语法**
-
-**1. LATERAL VIEW语法**
-
-```sql
--- ❌ Spark语法（不支持）
-SELECT user_id, event 
-FROM user_events LATERAL VIEW explode(event_array) AS event;
-
--- ✅ Lakehouse语法
-SELECT user_id, explode(event_array) as event 
-FROM user_events;
-```
-
-**2. 正则表达式函数**
-
-```sql
--- ❌ Spark语法（不支持）
-WHERE regexp_like(column_name, 'pattern')
-
--- ✅ Lakehouse替代方案
-WHERE regexp_extract(column_name, 'pattern', 0) != ''
--- 或者使用LIKE
-WHERE column_name LIKE '%pattern%'
-```
-
-**3. 类型转换差异**
-
-```sql
--- ⚠️ 注意：转换失败时返回特殊值而非NULL
-SELECT 
-    TRY_CAST('abc' AS INT) as result,  -- 返回nan，不是NULL
-    -- 安全转换方式
-    CASE 
-        WHEN TRY_CAST('abc' AS INT) IS NOT NULL 
-             AND CAST(TRY_CAST('abc' AS INT) AS STRING) != 'nan'
-        THEN TRY_CAST('abc' AS INT)
-        ELSE 0
-    END as safe_result;
-```
-
-**4. NULL值显示特性**
-
-```sql
--- ⚠️ 数值类型和时间类型的NULL有特殊显示格式
-SELECT 
-    LAG(order_date) OVER (...) as prev_date,     -- 时间类型NULL显示为"NaT"
-    LAG(customer_id) OVER (...) as prev_id,      -- 数值类型NULL显示为"nan"
-    CASE 
-        WHEN LAG(order_date) OVER (...) IS NULL  -- 但IS NULL判断仍然有效
-        THEN 'First Record'
-        ELSE 'Has Previous'
-    END as status
-FROM orders;
-```
-
-#### **复杂数据类型高级应用**
-
-```sql
--- Spark SQL数组操作（直接兼容）
-WITH user_events AS (
-    SELECT 
-        user_id,
-        array('login', 'view_product', 'purchase') as event_sequence
-    FROM user_activity
-)
-SELECT 
-    user_id,
-    event_sequence[0] as first_event,                    -- 索引从0开始（与Spark一致）
-    size(event_sequence) as event_count,
-    array_contains(event_sequence, 'purchase') as converted,
-    explode(event_sequence) as individual_event          -- 注意：不需要LATERAL VIEW
-FROM user_events;
-
--- Spark SQL结构体操作（完全兼容）
-WITH customer_profiles AS (
-    SELECT 
-        customer_id,
-        named_struct(
-            'name', customer_name,
-            'contact', named_struct(
-                'email', email,
-                'phone', phone
-            )
-        ) as profile
-    FROM customers
-)
-SELECT 
-    customer_id,
-    profile.name as customer_name,           -- 点号访问语法与Spark一致
-    profile.contact.email as email,
-    profile.contact.phone as phone
-FROM customer_profiles;
-```
-
-### 🗄️ **如果您习惯了MySQL/PostgreSQL**
-
-#### ✅ **可以直接复用的技能**
-
-```sql
--- 标准SQL查询完全兼容
-SELECT c.customer_name, COUNT(o.order_id) as order_count
-FROM customers c
-LEFT JOIN orders o ON c.customer_id = o.customer_id
-WHERE c.registration_date >= '2024-01-01'
-GROUP BY c.customer_id, c.customer_name;
-```
-
-#### 🔌 **MySQL用户的额外选择：MySQL协议支持**
-
-【**预览发布】云器Lakehouse支持MySQL协议连接**！
-
-```bash
-# ✅ 可以使用熟悉的MySQL连接方式
-# MySQL 8.x 连接方式
-jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com:3306/public?useSSL=true
-
-# MySQL 5.x 连接方式  
-jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com:3306/public?useSSL=false
-
-# 命令行连接
-mysql -h cn-shanghai-alicloud-mysql.api.clickzetta.com -P 3306 -u username -p database_name
-```
-
-**📊 主要用途**
-
-* **BI报表工具**：无法使用自定义JDBC驱动的报表工具
-* **遗留系统集成**：现有MySQL客户端应用快速接入
-* **开发工具兼容**：使用熟悉的MySQL管理工具
-
-**⚠️ 重要限制**
-
-* **语法仍为Lakehouse**：虽然协议兼容，但SQL语法需使用Lakehouse标准
-* **数据类型限制**：不支持MySQL特有类型（mediumint、text、blob、enum等）
-* **功能限制**：不支持mysqldump、LOAD等MySQL特有命令
-
-```sql
--- ❌ MySQL特有语法不支持
-CREATE TABLE test (col MEDIUMINT);  -- 报错
-SELECT CAST(value AS TEXT);         -- 报错
-
--- ✅ 使用Lakehouse对应类型
-CREATE TABLE test (col INT);        -- 正确
-SELECT CAST(value AS STRING);       -- 正确
-```
-
-**💡 选择建议**
-
-* **优先推荐**：使用Lakehouse原生驱动获得完整功能
-* **兼容场景**：无法使用原生驱动时选择MySQL协议
-
-#### ⚠️ **关键差异与工具限制**
-
-**1. 查询结果返回的工具限制**
-
-> 🎯 **核心理念**：查询返回的数据量往往受到您使用的工具或客户端限制，而非数据库引擎本身的限制。
-
-| 工具/客户端                      | 查询结果限制   | 适用场景     | 突破方案          |
-| --------------------------- | -------- | -------- | ------------- |
-| **Lakehouse Studio Web UI** | 最大10000行 | 数据探索、调试  | 添加WHERE条件过滤   |
-| **JDBC客户端**                 | 无硬性限制\*  | 应用开发、ETL | 分批处理、流式读取     |
-| **Python SDK**              | 无硬性限制\*  | 数据科学、脚本  | 分批处理、pandas分块 |
-| **BI工具**                    | 各工具不同    | 报表展示     | 查阅具体工具文档      |
-| **命令行工具**                   | 内存/配置限制  | 数据导出     | 调整配置或分批导出     |
-
-\*注：无硬性限制指SQL引擎层面无限制，但仍受内存、网络等资源限制。
-
-**2. 分页策略选择**
-
-```sql
--- 📱 Web UI 数据探索策略（受10000行限制）
-SELECT customer_id, order_count, total_amount
-FROM customer_summary
-WHERE registration_date >= '2024-01-01'  -- 先过滤
-  AND customer_type = 'premium'
-ORDER BY total_amount DESC
-LIMIT 100;  -- 小批量查看
-
--- 💻 编程接口大数据处理策略（无硬性限制）
-WITH batch_data AS (
-    SELECT customer_id, order_id, amount
-    FROM orders 
-    WHERE order_date = '2024-06-01'
-      AND customer_id BETWEEN :start_id AND :end_id  -- 批次范围
-)
-SELECT * FROM batch_data;
-
--- 🔄 推荐：基于游标的分页（适用所有工具）
-SELECT customer_id, order_id, order_date, amount
-FROM orders 
-WHERE customer_id > :last_customer_id  -- 游标分页
-  AND order_date >= '2024-01-01'
-ORDER BY customer_id, order_id
-LIMIT 1000;  -- 适中的批次大小
-```
-
-**3. 字符串函数兼容性**
-
-```sql
--- ✅ MySQL风格函数大多兼容
-SELECT 
-    SUBSTRING(name, 1, 5) as substr_mysql,    -- 支持
-    SUBSTR(name, 1, 5) as substr_standard,    -- 支持
-    CONCAT_WS(',', field1, field2) as concat_ws,  -- 支持
-    CONCAT(field1, ',', field2) as concat_std     -- 支持
-FROM users;
-```
-
-**4. 索引概念差异**
-
-```sql
--- ❌ 传统数据库思维
-CREATE INDEX idx_name ON table(column);  -- 期望立即生效
-
--- ✅ Lakehouse正确做法
-CREATE BLOOMFILTER INDEX idx_name ON TABLE table(column);  -- 仅对新数据生效
--- 如需对已有数据生效（仅部分索引类型支持）
-BUILD INDEX idx_name ON table;
-```
-
-**5. 事务和锁定**
-
-```sql
--- ⚠️ Lakehouse不支持传统事务语法
--- ❌ 不支持
-BEGIN TRANSACTION;
-UPDATE products SET price = price * 1.1;
-COMMIT;
-
--- ✅ 使用批量更新或MERGE语句
-MERGE INTO products p
-USING (SELECT product_id, price * 1.1 as new_price FROM products) src
-ON p.product_id = src.product_id
-WHEN MATCHED THEN UPDATE SET price = src.new_price;
-```
-
-### 📊 **列式存储优化思维**
-
-#### **传统行式 vs 列式存储**
-
-```sql
--- ❌ 行式数据库思维：避免SELECT *
-SELECT * FROM large_table WHERE id = 123;
-
--- ✅ 列式存储优化：明确指定列
-SELECT customer_id, order_amount, order_date 
-FROM large_table 
-WHERE id = 123;
-
--- 💡 列式存储的优势
-SELECT 
-    product_category,
-    AVG(price) as avg_price,  -- 只读取price列，性能优异
-    COUNT(*) as product_count
-FROM products 
-GROUP BY product_category;
-```
-
-#### **分区概念理解**
-
-```sql
--- 💡 分区表查询优化
--- ✅ 正确：直接使用分区字段
-SELECT * FROM orders 
-WHERE order_date >= '2024-06-01' 
-  AND order_date <= '2024-06-30';
-
--- ❌ 错误：对分区字段使用函数
-SELECT * FROM orders 
-WHERE YEAR(order_date) = 2024;  -- 无法利用分区裁剪
-```
-
-### 🚨 **常见错误和解决方案**
-
-#### **1. 数据类型选择错误**
-
-```sql
--- ❌ 错误选择：JSON数据存储为字符串
-CREATE TABLE user_profiles (
-    user_id INT,
-    profile_data STRING  -- 需要类型转换才能使用JSON函数
-);
-
--- ✅ 正确选择：使用原生JSON类型
-CREATE TABLE user_profiles (
-    user_id INT,
-    profile_data JSON    -- 直接支持JSON函数，性能更好
-);
-
--- 查询语法对比
--- STRING类型：需要转换
-SELECT user_id, json_extract_string(CAST(profile_data AS JSON), '$.age') as age
-FROM user_profiles_string;
-
--- JSON类型：直接使用
-SELECT user_id, json_extract_string(profile_data, '$.age') as age
-FROM user_profiles_json;
-```
-
-#### **2. JOIN优化误区**
-
-```sql
--- ❌ 传统数据库思维：大表在左
-SELECT l.*, s.name
-FROM large_table l
-JOIN small_table s ON l.id = s.id;
-
--- ✅ Lakehouse优化：使用MAPJOIN提示
-SELECT /*+ MAPJOIN(small_table) */ l.*, s.name
-FROM large_table l
-JOIN small_table s ON l.id = s.id;
-```
-
-#### **3. 聚合查询优化**
-
-```sql
--- ❌ 低效：多次扫描大表
-SELECT 
-    (SELECT COUNT(*) FROM large_table WHERE status = 'active') as active_count,
-    (SELECT COUNT(*) FROM large_table WHERE status = 'inactive') as inactive_count;
-
--- ✅ 高效：一次扫描
-SELECT 
-    SUM(CASE WHEN status = 'active' THEN 1 ELSE 0 END) as active_count,
-    SUM(CASE WHEN status = 'inactive' THEN 1 ELSE 0 END) as inactive_count
-FROM large_table;
-```
-
-### 💡 **快速适应建议**
-
-#### **1. 优先使用的功能**
-
-* **JSON数据类型**：替代字符串存储半结构化数据
-* **VECTOR数据类型**：原生支持向量搜索
-* **分区表**：按时间或业务维度分区
-* **列式索引**：BLOOMFILTER、INVERTED、VECTOR
-* **MySQL协议连接**：无法使用原生驱动时的兼容选择
-
-#### **2. 性能优化习惯**
-
-```sql
--- 好习惯：分区+列选择+索引
-SELECT customer_id, order_amount
-FROM orders 
-WHERE order_date >= '2024-06-01'     -- 分区裁剪
-  AND customer_type = 'premium'      -- 布隆过滤器索引
-  AND match_any(description, '手机', map('analyzer', 'chinese'))  -- 全文索引
-ORDER BY order_amount DESC
-LIMIT 100;
-```
-
-#### **3. 避免的反模式**
-
-```sql
--- ❌ 避免的模式
--- 1. 在分区字段上使用函数
-WHERE YEAR(partition_date) = 2024
-
--- 2. 过度使用SELECT *
-SELECT * FROM large_table
-
--- 3. 忽略数据类型优化
-profile_json STRING  -- 应该用JSON类型
-
--- 4. 忽略工具限制的深度分页（Web UI）
--- 在Studio中查询大量数据时没有添加过滤条件
-
--- 5. 大表全量排序分页
-SELECT * FROM huge_table ORDER BY random_column LIMIT 100 OFFSET 5000  -- 性能极差
-```
-

-ORDER BY total_orders DESC
-LIMIT 100;
-
--- 聚合查询
-SELECT 
-    product_category,
-    COUNT(*) as product_count,
-    AVG(price) as avg_price,
-    SUM(sales_amount) as total_sales
-FROM products
-GROUP BY product_category
-HAVING COUNT(*) > 10;
-```
-
-### 增强语法特性
-
-#### EXCEPT子句
-
-Lakehouse提供了EXCEPT子句用于排除指定列：
-
-```sql
--- 排除敏感字段
-SELECT * EXCEPT(password, credit_card, ssn)
-FROM user_accounts;
-
--- 排除多个字段
-SELECT * EXCEPT(internal_id, created_by, updated_by)
-FROM public_data;
-```

-
-### 复杂数据类型
-
-#### ARRAY类型
-
-```sql
--- 创建和操作数组
-SELECT 
-    array(1, 2, 3, 4, 5) as numbers,
-    array('apple', 'banana', 'orange') as fruits,
-    array_contains(array(1, 2, 3), 2) as contains_check,
-    size(array(1, 2, 3, 4)) as array_length;
-
--- 数组访问和处理
-WITH data AS (
-    SELECT array('a', 'b', 'c', 'd') as letters
-)
-SELECT 
-    letters[0] as first_letter,    -- 索引从0开始
-    letters[3] as last_letter,
-    slice(letters, 1, 2) as middle_slice,  -- 从索引1开始，取2个元素
-    array_sort(letters) as sorted_letters
-FROM data;
-```
-
-**⚠️ 重要说明**：`slice(array, start_index, length)` 函数参数含义：
-
-* `start_index`：起始索引位置（从0开始）
-* `length`：要提取的元素个数
-* 示例：`slice(array('a','b','c','d'), 1, 2)` 返回 `['b', 'c']`
-
-#### STRUCT类型
-
-```sql
--- 创建和访问结构体
-SELECT 
-    named_struct('name', 'Alice', 'age', 30, 'city', 'Seattle') as person,
-    named_struct(
-        'street', '123 Main St',
-        'city', 'Seattle',
-        'zipcode', '98101'
-    ) as address;
-
--- 结构体字段访问
-WITH customer_data AS (
-    SELECT 
-        1 as id,
-        named_struct(
-            'name', 'Alice Johnson',
-            'contact', named_struct(
-                'email', 'alice@example.com',
-                'phone', '555-1234'
-            )
-        ) as profile
-)
-SELECT 
-    id,
-    profile.name as customer_name,
-    profile.contact.email as email,
-    profile.contact.phone as phone
-FROM customer_data;
-```
-
-#### JSON类型
-
-JSON作为一等公民提供原生支持，具有优异的查询性能：
-
-```sql
--- JSON字面量和函数
-SELECT 
-    JSON '{"name": "Alice", "age": 30, "skills": ["Python", "SQL"]}' as profile,
-    json_extract_string(JSON '{"name": "Alice"}', '$.name') as name,
-    json_extract_int(JSON '{"age": 30}', '$.age') as age,
-    json_extract(JSON '{"skills": ["Python", "SQL"]}', '$.skills') as skills;
-
--- JSON查询和过滤
-WITH user_profiles AS (
-    SELECT 
-        1 as user_id,
-        JSON '{"name": "Alice", "department": "Engineering", "skills": ["Python", "Java"]}' as profile
-    UNION ALL
-    SELECT 2, JSON '{"name": "Bob", "department": "Sales", "skills": ["Excel", "CRM"]}'
-)
-SELECT 
-    user_id,
-    json_extract_string(profile, '$.name') as name,
-    json_extract_string(profile, '$.department') as department,
-    json_extract(profile, '$.skills[0]') as primary_skill
-FROM user_profiles
-WHERE json_extract_string(profile, '$.department') = 'Engineering';
-```
-
-#### VECTOR类型
-
-专为AI/ML场景设计的向量数据类型：
-
-```sql
--- 向量创建和计算
-SELECT 
-    VECTOR(0.1, 0.2, 0.3, 0.4) as embedding_vector,
-    l2_distance(VECTOR(0.1, 0.2, 0.3), VECTOR(0.4, 0.5, 0.6)) as l2_dist,
-    cosine_distance(VECTOR(0.1, 0.2, 0.3), VECTOR(0.4, 0.5, 0.6)) as cosine_sim,
-    dot_product(VECTOR(1.0, 2.0, 3.0), VECTOR(2.0, 3.0, 4.0)) as dot_prod;
-```
-
-### 类型转换
-
-#### 基本转换语法
-
-Lakehouse支持多种类型转换语法：
-
-```sql
--- 三种转换方式
-SELECT 
-    CAST(123 AS STRING) as cast_syntax,
-    123::STRING as double_colon_syntax,
-    STRING(123) as function_syntax;
-```
-
-#### 安全类型转换
-
-转换失败时的处理机制：
-
-```sql
--- TRY_CAST安全转换
-SELECT 
-    '123' as original,
-    TRY_CAST('123' AS INT) as valid_conversion,      -- 返回123
-    TRY_CAST('abc' AS INT) as invalid_conversion,    -- 返回nan
-    
-    -- 转换验证
-    CASE 
-        WHEN TRY_CAST('123' AS INT) IS NOT NULL 
-             AND CAST(TRY_CAST('123' AS INT) AS STRING) != 'nan'
-        THEN 'VALID'
-        ELSE 'INVALID'
-    END as conversion_status;
-```
-
-### 🚨 **NULL值显示特性**
-
-**重要说明**：Lakehouse中NULL值的显示具有特殊性：
-
-```sql
--- ⚠️ 数值类型和时间类型的NULL值有特殊显示格式
-SELECT 
-    customer_id,
-    LAG(customer_id) OVER (ORDER BY registration_date) as prev_id,        -- 数值NULL显示为"nan"
-    LAG(registration_date) OVER (ORDER BY registration_date) as prev_date, -- 时间NULL显示为"NaT"
-    
-    -- 但IS NULL/IS NOT NULL逻辑判断完全正常
-    CASE 
-        WHEN LAG(customer_id) OVER (ORDER BY registration_date) IS NULL 
-        THEN 'First Customer'
-        ELSE 'Has Previous'
-    END as position_status
-FROM customers;
-```
-
-**关键要点**：
-
-* **数值类型**（INT、DOUBLE等）的NULL显示为 `"nan"`
-* **时间类型**（DATE、TIMESTAMP等）的NULL显示为 `"NaT"`
-* **字符类型**（STRING、VARCHAR等）的NULL正常显示
-* **所有类型的`IS NULL`和`IS NOT NULL`判断都正常工作**

-
-```sql
--- 查询指定时间范围的数据
-SELECT * FROM orders 
-WHERE created_time >= '2024-06-01 00:00:00'
-  AND created_time <= '2024-06-01 23:59:59';
-
--- 查询相对时间的数据
-SELECT * FROM orders 
-WHERE created_time >= CURRENT_TIMESTAMP() - INTERVAL '1' HOUR;
-```
-
-***
-
-## 索引优化
-
-云器Lakehouse支持三种类型的索引来优化查询性能，每种索引针对不同的查询场景：
-
-### 索引类型概览
-
-| 索引类型        | 适用场景    | 支持的数据类型                          | 查询函数                                |
-| ----------- | ------- | -------------------------------- | ----------------------------------- |
-| BLOOMFILTER | 等值查询过滤  | 除interval、struct、map、array外的基本类型 | 标准WHERE条件                           |
-| INVERTED    | 全文搜索    | STRING类型                         | match\_all、match\_any、match\_phrase |
-| VECTOR      | 向量相似性搜索 | VECTOR类型                         | cosine\_distance、l2\_distance等      |
-
-### 1. 布隆过滤器索引 (BLOOMFILTER INDEX)
-
-布隆过滤器索引用于快速过滤等值查询，特别适用于高基数列。
-
-#### 创建语法
-
-```sql
--- 基础语法
-CREATE BLOOMFILTER INDEX [IF NOT EXISTS] index_name 
-ON TABLE [schema].table_name(column_name) 
-[COMMENT 'comment'] 
-[PROPERTIES ('key'='value')];
-
--- 示例
-CREATE BLOOMFILTER INDEX idx_customer_id 
-ON TABLE orders(customer_id) 
-COMMENT '客户ID布隆过滤器索引';
-```
-
-#### 使用示例
-
-```sql
--- 创建测试表
-CREATE TABLE product_sales (
-    product_id INT,
-    category STRING,
-    sales_amount DOUBLE,
-    sale_date DATE
-);
-
--- 创建布隆过滤器索引
-CREATE BLOOMFILTER INDEX idx_category_bloom 
-ON TABLE product_sales(category) 
-COMMENT '产品类别布隆过滤器索引';
-
--- 使用索引进行等值查询（索引会自动应用）
-SELECT product_id, sales_amount
-FROM product_sales
-WHERE category = '电子产品';  -- 布隆过滤器加速此查询
-```
-
-#### 限制说明
-
-* **仅对新数据生效**：创建后只对新写入的数据有效，已有数据需要重写
-* **不支持BUILD INDEX**：布隆过滤器索引不支持对存量数据构建索引
-* **数据类型限制**：不支持interval、struct、map、array等复杂类型
-
-### 2. 倒排索引 (INVERTED INDEX)
-
-倒排索引用于全文搜索功能，支持多种文本分析器。
-
-#### 创建语法
-
-```sql
--- 建表时创建
-CREATE TABLE documents (
-    doc_id INT,
-    title STRING,
-    content STRING,
-    INDEX content_idx (content) INVERTED COMMENT '内容倒排索引'
-);
-
--- 已有表添加索引
-CREATE INVERTED INDEX [IF NOT EXISTS] index_name 
-ON TABLE [schema].table_name(column_name) 
-PROPERTIES('analyzer'='analyzer_type');
-```
-
-#### 分析器类型
-
-| 分析器     | 适用场景  | 说明          |
-| ------- | ----- | ----------- |
-| chinese | 中文文本  | 支持中文分词      |
-| english | 英文文本  | 英文分词和词干提取   |
-| keyword | 关键词匹配 | 不分词，完整匹配    |
-| unicode | 通用文本  | Unicode字符处理 |
-
-#### 使用示例
-
-```sql
--- 创建倒排索引
-CREATE INVERTED INDEX IF NOT EXISTS idx_content_search 
-ON TABLE documents(content)

-ON TABLE [schema].table_name(column_name) 
-PROPERTIES(
-    "scalar.type" = "scalar_type",
-    "distance.function" = "distance_function",
-    "ef_construction" = "ef_value",
-    "M" = "M_value"
-);
-```
-
-#### 参数说明
-
-| 参数                | 可选值                                                                  | 默认值              | 说明              |
-| ----------------- | -------------------------------------------------------------------- | ---------------- | --------------- |
-| scalar.type       | f32, f16, i8, b1                                                     | f32              | 向量标量类型          |

-
-#### 使用示例
-
-```sql
--- 创建包含向量列的表
-CREATE TABLE document_embeddings (
-    doc_id INT,
-    title STRING,
-    embedding VECTOR(512),  -- 512维向量
-    created_at TIMESTAMP_LTZ
-);
-
--- 创建向量索引
-CREATE VECTOR INDEX IF NOT EXISTS idx_doc_embedding 
-ON TABLE document_embeddings(embedding) 
-PROPERTIES(
-    "scalar.type" = "f32",
-    "distance.function" = "cosine_distance",
-    "ef_construction" = "200",
-    "M" = "16"
-) COMMENT '文档向量嵌入索引';
-
--- 构建索引
-BUILD INDEX idx_doc_embedding ON document_embeddings;
-
--- 向量相似性搜索
-WITH query_vector AS (
-    SELECT VECTOR(0.1, 0.2, 0.3, ...) as search_embedding  -- 查询向量
-)
-SELECT 
-    d.doc_id,
-    d.title,
-    cosine_distance(d.embedding, q.search_embedding) as similarity_score
-FROM document_embeddings d
-CROSS JOIN query_vector q
-WHERE cosine_distance(d.embedding, q.search_embedding) < 0.5  -- 相似度阈值
-ORDER BY similarity_score
-LIMIT 10;
-
--- 使用其他距离函数
-SELECT 
-    doc_id,
-    title,
-    l2_distance(embedding, VECTOR(0.1, 0.2, 0.3)) as l2_dist,
-    dot_product(embedding, VECTOR(0.1, 0.2, 0.3)) as dot_prod
-FROM document_embeddings
-ORDER BY l2_dist
-LIMIT 5;
-```
-
-### 索引管理
-
-#### 创建索引的IF NOT EXISTS支持
-
-**✅ 语法支持**：所有三种索引类型都支持 `IF NOT EXISTS` 语法：
-
-```sql
--- 布隆过滤器索引
-CREATE BLOOMFILTER INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
-
--- 倒排索引
-CREATE INVERTED INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
-
--- 向量索引
-CREATE VECTOR INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
-```
-
-**⚠️ 当前实现说明**：虽然语法已支持，但在同一列创建相同类型的重复索引时仍可能报错。这表明语法解析正确，但逻辑检查还在持续完善中。
-
-#### 构建索引 (BUILD INDEX)
-
-对已有数据构建索引，仅支持INVERTED和VECTOR索引：
-
-```sql
--- 全表构建
-BUILD INDEX index_name ON [schema].table_name;
-
--- 分区构建
-BUILD INDEX index_name ON table_name 
-WHERE partition_col = 'value' AND other_col > 100;
-
--- 多分区构建
-BUILD INDEX index_name ON table_name 
-WHERE partition_date >= '2024-06-01' 
-  AND partition_date <= '2024-06-30';
-```
-
-#### 查看索引信息
-
-```sql
--- 查看表的所有索引
-DESCRIBE TABLE table_name;
-
--- 查看特定索引详情
-DESCRIBE INDEX index_name;
-
--- 扩展索引信息
-DESCRIBE INDEX EXTENDED index_name;
-```
-
-#### 删除索引
-
-```sql
-DROP INDEX [IF EXISTS] index_name;
-```
-
-### 查询优化建议
-
-#### 复合搜索：结合多种索引
-
-```sql
--- 结合布隆过滤器和全文搜索
-SELECT doc_id, title, content
-FROM documents
-WHERE category = 'technology'  -- 布隆过滤器索引加速
-  AND match_any(content, '人工智能', map('analyzer', 'chinese'));  -- 倒排索引搜索
-
--- 向量搜索与过滤结合
-SELECT doc_id, title, embedding,
-       cosine_distance(embedding, VECTOR(0.1, 0.2, 0.3)) as score
-FROM document_embeddings
-WHERE doc_type = 'article'  -- 先过滤再向量搜索
-  AND cosine_distance(embedding, VECTOR(0.1, 0.2, 0.3)) < 0.3
-ORDER BY score
-LIMIT 20;
-```
-
-***
-
-## 性能优化
-
-### 查询优化原则
-
-#### 分区裁剪优化
-
-```sql
--- 正确的分区查询方式
-SELECT *
-FROM partitioned_table
-WHERE date_partition >= '2024-06-01'
-  AND date_partition <= '2024-06-30'
-  AND status = 'active';
-
--- 避免的反模式
--- WHERE year(date_partition) = 2024  -- 无法利用分区裁剪
-```
-
-#### 谓词下推优化
-
-```sql
--- 在JOIN前过滤数据
-WITH filtered_orders AS (
-    SELECT customer_id, order_id, total_amount
-    FROM orders
-    WHERE order_date >= '2024-06-01'
-      AND total_amount > 100
-),
-active_customers AS (
-    SELECT customer_id, customer_name
-    FROM customers
-    WHERE status = 'active'
-)
-SELECT c.customer_name, o.order_id, o.total_amount
-FROM active_customers c
-JOIN filtered_orders o ON c.customer_id = o.customer_id;
-```
-
-#### 列裁剪优化
-
-```sql
--- 只选择需要的列
-SELECT customer_id, customer_name, total_orders
-FROM customers
-WHERE registration_date >= '2024-01-01';
-
--- 使用EXCEPT排除不需要的列
-SELECT * EXCEPT(internal_notes, created_by, updated_by)
-FROM customer_details;
-```
-
-### 分页查询优化策略
-
-根据使用的工具选择合适的分页策略：
-
-#### **📱 Web UI 分页策略**
-
-适用于：Lakehouse Studio界面探索（受10000行显示限制）
-
-```sql
--- 策略1：条件过滤 + 小批量查看
-SELECT customer_id, order_count, last_order_date
-FROM customer_summary
-WHERE customer_type = 'premium'     -- 先过滤
-  AND last_order_date >= '2024-01-01'
-ORDER BY order_count DESC
-LIMIT 100;  -- 在显示限制内
-
--- 策略2：时间窗口分页
-SELECT order_id, customer_id, amount
-FROM orders
-WHERE order_date >= '2024-06-01 00:00:00'
-  AND order_date < '2024-06-01 06:00:00'  -- 6小时窗口
-ORDER BY order_date
-LIMIT 1000;
-
--- 策略3：分类查看
-SELECT product_id, product_name, price
-FROM products
-WHERE category = 'electronics'  -- 单一类别
-ORDER BY price DESC
-LIMIT 500;
-```
-
-#### **💻 编程接口分页策略**
-
-适用于：JDBC、Python SDK等客户端（无硬性行数限制）
-
-```sql
--- 策略1：基于游标的分页（推荐）
--- 第一页
-SELECT customer_id, order_id, order_date, amount
-FROM orders 
-WHERE customer_id >= 0  -- 起始点
-ORDER BY customer_id, order_id
-LIMIT 1000;
-
--- 下一页（基于上一页的最后一条记录）
-SELECT customer_id, order_id, order_date, amount
-FROM orders 
-WHERE customer_id > :last_customer_id  -- 游标位置
-   OR (customer_id = :last_customer_id AND order_id > :last_order_id)
-ORDER BY customer_id, order_id
-LIMIT 1000;
-
--- 策略2：范围分页
--- 第一批：ID 0-9999
-SELECT * FROM large_table 
-WHERE id BETWEEN 0 AND 9999
-ORDER BY id;
-
--- 第二批：ID 10000-19999
-SELECT * FROM large_table 
-WHERE id BETWEEN 10000 AND 19999
-ORDER BY id;
-
--- 策略3：时间分区分页
--- 处理2024年6月的数据，按天分批
-SELECT * FROM orders 
-WHERE order_date >= '2024-06-01'
-  AND order_date < '2024-06-02'
-ORDER BY order_id;
-```
-
-#### **🔄 流式处理策略**
-
-适用于：大数据ETL、数据导出场景
-
-```sql
--- 策略1：分批流式处理
--- Python伪代码示例
-"""
-batch_size = 50000
-offset = 0
-while True:
-    sql = f'''
-    SELECT * FROM large_table 
-    WHERE process_date = '2024-06-01'
-    ORDER BY id 
-    LIMIT {batch_size} OFFSET {offset}
-    '''
-    rows = execute_query(sql)
-    if not rows:
-        break
-    process_batch(rows)
-    offset += batch_size
-"""
-
--- 策略2：条件迭代处理  
--- 适用于有序主键的表
-"""
-last_id = 0
-batch_size = 50000
-while True:
-    sql = f'''
-    SELECT * FROM large_table 
-    WHERE id > {last_id}
-    ORDER BY id 
-    LIMIT {batch_size}
-    '''
-    rows = execute_query(sql)
-    if not rows:
-        break
-    process_batch(rows)
-    last_id = rows[-1]['id']
-"""
-```
-
-### 性能调优建议
-
-#### 1. 索引选择策略
-
-* **高基数等值查询**：使用BLOOMFILTER索引
-* **文本搜索需求**：使用INVERTED索引，选择合适的分析器
-* **向量相似性搜索**：使用VECTOR索引，调整ef\_construction和M参数
-
-#### 2. 构建策略
-
-* **大表分区构建**：分批构建索引，避免单次处理过多数据
-* **业务低峰期构建**：BUILD INDEX是同步操作，消耗计算资源
-* **监控构建进度**：通过Job Profile查看构建状态
-
-#### 3. 查询优化
-
-```sql
--- 推荐：分区裁剪 + 索引过滤
-SELECT *
-FROM partitioned_table
-WHERE partition_date >= '2024-06-01'  -- 分区裁剪
-  AND category = 'electronics'        -- 布隆过滤器索引
-  AND match_any(description, '手机', map('analyzer', 'chinese'));  -- 倒排索引
-
--- 避免：在索引列上使用函数
--- 错误示例
-WHERE UPPER(category) = 'ELECTRONICS'  -- 无法利用索引
-
--- 正确示例
-WHERE category = 'electronics'  -- 可以利用索引
-```
-
-***
-
-## 最佳实践
-
-### 查询编写建议
-
-1. **明确指定列名**：避免使用`SELECT *`，明确指定需要的列
-2. **合理使用索引**：为高频查询的过滤条件创建适当的索引
-3. **优化JOIN顺序**：将小表放在JOIN的右侧，使用MAPJOIN提示
-4. **使用分区裁剪**：在WHERE条件中直接使用分区字段
-5. **避免函数包装分区字段**：不要对分区字段使用函数
-6. **了解工具限制**：根据使用的客户端选择合适的查询策略
-
-### 数据类型选择建议
-
-1. **半结构化数据优先选择JSON**：性能优于STRING存储
-2. **时间数据根据场景选择TIMESTAMP\_LTZ或TIMESTAMP\_NTZ**
-3. **向量数据使用VECTOR类型**：获得原生性能优化
-4. **大文本数据考虑全文搜索需求**：可配合相应的搜索功能使用
-5. **理解NULL值显示特性**：数值和时间类型NULL有特殊显示格式
-
-### 索引最佳实践
-
-1. **合理选择索引类型**：根据查询模式选择合适的索引
-2. **避免过度索引**：索引会增加存储成本和写入开销
-3. **定期维护索引**：监控索引使用情况和性能影响
-4. **测试验证效果**：创建索引后验证查询性能提升
-5. **考虑数据特征**：高基数列适合布隆过滤器，文本列适合倒排索引
-
-### 错误处理建议
-
-1. **使用TRY\_CAST进行安全类型转换**
-2. **检查转换结果是否为"nan**"
-3. **为窗口函数的NULL结果提供合适的默认值处理**
-4. **在数据质量检查中识别和处理异常值**
-
-### 工具链选择建议

-
-## 常见问题
-
-### Q: 是否支持递归CTE（WITH RECURSIVE）？
-
-A: 当前版本不支持递归CTE语法。对于层次化数据处理，可以使用多级JOIN或自连接方式：
-
-```sql
--- 替代方案：使用多级JOIN处理层次数据
-WITH level_1 AS (
-    SELECT employee_id, employee_name, 1 as level
-    FROM employees WHERE manager_id IS NULL
-),
-level_2 AS (
-    SELECT e.employee_id, e.employee_name, 2 as level
-    FROM employees e
-    JOIN level_1 l1 ON e.manager_id = l1.employee_id
-)
-SELECT * FROM level_1
-UNION ALL
-SELECT * FROM level_2;
-```
-
-### Q: 如何查询历史版本数据？
-
-A: 当前建议使用时间字段进行历史数据查询：
-
-```sql
--- 使用创建时间字段查询历史数据
-SELECT * FROM orders 
-WHERE created_time >= '2024-06-01 00:00:00'
-  AND created_time <= '2024-06-01 23:59:59';
-
--- 查询相对时间的数据
-SELECT * FROM orders 
-WHERE created_time >= CURRENT_TIMESTAMP() - INTERVAL '1' HOUR;
-```
-
-### Q: 为什么类型转换失败时返回"nan"而不是NULL？
-
-A: Lakehouse采用更宽松的类型转换策略，转换失败时返回特殊值"nan"。可以使用以下方式进行安全转换：
-
-```sql
--- 检查转换是否成功
-SELECT 
-    CASE 
-        WHEN TRY_CAST(column AS INT) IS NOT NULL 
-             AND CAST(TRY_CAST(column AS INT) AS STRING) != 'nan'
-        THEN TRY_CAST(column AS INT)
-        ELSE 0  -- 或其他默认值
-    END as safe_converted_value
-FROM table_name;
-```
-
-### Q: 窗口函数中的NULL值为什么显示为特殊格式？
-
-A: 这是Lakehouse中数值类型和时间类型NULL值的特殊显示方式：
-
-```sql
--- 数值类型NULL显示为"nan"，时间类型NULL显示为"NaT"
-SELECT 
-    LAG(customer_id) OVER (...) as prev_id,      -- 显示为"nan"
-    LAG(timestamp_column) OVER (...) as prev_time, -- 显示为"NaT"
-    CASE 
-        WHEN LAG(timestamp_column) OVER (...) IS NULL   -- IS NULL判断仍然有效
-        THEN 'No Previous Value'
-        ELSE 'Has Previous Value'
-    END as status
-FROM table_name;
-```
-
-### Q: 如何迁移Spark中的regexp\_like函数？
-
-A: Lakehouse不支持regexp\_like函数，可以使用以下替代方案：
-
-```sql
--- 替代方案1：使用LIKE
-WHERE column_name LIKE '%pattern%'
-
--- 替代方案2：使用regexp_extract检查是否有匹配
-WHERE regexp_extract(column_name, 'pattern', 0) != ''
-
--- 替代方案3：组合多个条件
-WHERE column_name LIKE '%pattern1%' OR column_name LIKE '%pattern2%'
-```
-
-### Q: LATERAL VIEW explode语法不支持怎么办？
-
-A: 直接使用explode函数，无需LATERAL VIEW：
-
-```sql
--- Spark语法
--- SELECT id, item FROM table LATERAL VIEW explode(array_column) AS item;
-
--- Lakehouse语法
-SELECT id, explode(array_column) as item FROM table;
-```
-
-### Q: 哪些索引支持BUILD INDEX？
-
-A: 只有INVERTED索引和VECTOR索引支持BUILD INDEX命令：
-
-```sql
--- 支持BUILD INDEX
-BUILD INDEX inverted_idx ON table_name;   -- 倒排索引
-BUILD INDEX vector_idx ON table_name;     -- 向量索引
-
--- 不支持BUILD INDEX
--- BUILD INDEX bloom_idx ON table_name;   -- 布隆过滤器索引不支持
-```
-
-布隆过滤器索引只对新写入的数据生效，如需对已有数据生效，需要重写数据。
-
-### Q: Web UI显示只有10000行，但我的数据有更多，如何查看全部？
-
-A: 这是Web UI的显示限制，不是数据库的限制。建议：
-
-```sql
--- Web UI策略：添加过滤条件
-SELECT * FROM large_table 
-WHERE category = 'electronics'  -- 先过滤
-  AND created_date >= '2024-06-01'
-LIMIT 1000;
-
--- 或使用WEB UI的全量下载功能下载后再查看
-
--- 或使用编程接口处理全量数据
--- Python示例：
-"""
-import clickzetta
-conn = clickzetta.connect(...)
-cursor = conn.cursor()
-cursor.execute("SELECT * FROM large_table")
-for row in cursor.fetchall():  -- 可处理超过10000行
-    process(row)
-"""
-```
-
-### Q: 不同工具的查询限制如何确认？
-
-A: 建议在实际使用前测试：
-
-1. **Web UI**：已知限制10000行
-2. **JDBC客户端**：通过简单查询测试实际限制
-3. **Python SDK**：查阅官方文档或测试验证
-4. **BI工具**：查阅工具文档或联系厂商
-5. **自定义应用**：在开发环境中进行压力测试
-
-### Q: OFFSET功能有限制吗？
-
-A: 经过实际验证，Lakehouse的OFFSET功能没有硬性限制：
-
-```sql
--- ✅ 这些查询都可以正常执行
-SELECT * FROM table ORDER BY id LIMIT 10 OFFSET 10000;   -- 正常
-SELECT * FROM table ORDER BY id LIMIT 10 OFFSET 15000;   -- 正常
-SELECT * FROM table ORDER BY id LIMIT 10 OFFSET 50000;   -- 正常
-
--- 限制主要来自：
--- 1. 使用的客户端工具的显示限制
--- 2. 网络传输和内存的实际约束
--- 3. 查询性能考虑（深度分页性能较差）
-```
-
-### Q: 索引的IF NOT EXISTS语法有什么特殊行为？
-
-A: 语法完全支持，但当前实现有些特殊性：
-
-```sql
--- ✅ 语法支持
-CREATE BLOOMFILTER INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
-CREATE INVERTED INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
-CREATE VECTOR INDEX IF NOT EXISTS idx_name ON TABLE table_name(column);
-
--- ⚠️ 当前行为：在同一列创建相同类型的重复索引时仍可能报错
--- 这表明语法解析正确，但逻辑检查还在持续完善中
-```
-
-建议在生产环境中谨慎使用，必要时先检查索引是否已存在。

-## CTE核心语法与通用特性
-
-### 标准语法结构
-
-```sql
-WITH <cte_name1> AS (
-    SELECT column1, column2, ...
-    FROM table_name
-    WHERE condition
-),
-<cte_name2> AS (
-    SELECT column1, column2, ...
-    FROM <cte_name1>  -- 可引用前面定义的CTE
-    WHERE condition
-)
-SELECT ...
-FROM <cte_name1>
-JOIN <cte_name2> ON ...
-```
-
-### 核心优势对比
-
-| 特性 | 传统子查询 | WITH CTE | 优势体现 |
-|------|-----------|----------|----------|
-| **可读性** | 嵌套复杂 | 逻辑清晰 | 分步骤构建，易于理解 |
-| **复用性** | 重复代码 | 多次引用 | 避免重复，提高效率 |

-## Spark用户迁移指南
-
-### 概念映射与迁移要点
-
-Spark用户熟悉的DataFrame操作链式调用在Lakehouse中通过CTE得到完美体现：
-
-```python
-# Spark DataFrame操作思维
-df_filtered = df.filter(col("order_date") >= "2024-01-01")
-df_grouped = df_filtered.groupBy("customer_id").agg(
-    sum("amount").alias("total_amount"),
-    count("*").alias("order_count")
-)
-df_result = df_grouped.filter(col("total_amount") > 1000)
-```
-
-**云器Lakehouse CTE等价实现**：
-
-```sql
--- CTE链式逻辑：直观对应DataFrame操作
-WITH filtered_orders AS (
-    -- 对应 df.filter()
-    SELECT customer_id, order_date, amount
-    FROM orders
-    WHERE order_date >= '1995-01-01'
-),
-grouped_summary AS (
-    -- 对应 df.groupBy().agg()
-    SELECT 
-        customer_id,
-        SUM(amount) as total_amount,
-        COUNT(*) as order_count
-    FROM filtered_orders
-    GROUP BY customer_id
-),
-final_result AS (
-    -- 对应后续的 filter()
-    SELECT customer_id, total_amount, order_count
-    FROM grouped_summary
-    WHERE total_amount > 1000
-)
-SELECT * FROM final_result
-ORDER BY total_amount DESC;
-```
-
-### DataFrame API到CTE的转换模式
-
-#### 1. 复杂聚合操作转换
-
-```python
-# Spark复杂聚合
-from pyspark.sql.functions import *
-from pyspark.sql.window import Window
-
-window_spec = Window.partitionBy("category").orderBy("date")
-result = df.withColumn("running_total", 
-                      sum("amount").over(window_spec)) \
-           .withColumn("rank", 
-                      row_number().over(window_spec.orderBy(desc("amount"))))
-```
-
-**Lakehouse CTE实现**：
-
-```sql
--- 窗口函数与CTE结合：更直观的逻辑表达
-WITH enriched_data AS (
-    SELECT 
-        category,
-        date,
-        amount,
-        -- 对应Spark的window functions
-        SUM(amount) OVER (
-            PARTITION BY category 
-            ORDER BY date 
-            ROWS UNBOUNDED PRECEDING
-        ) as running_total,
-        ROW_NUMBER() OVER (
-            PARTITION BY category 
-            ORDER BY amount DESC
-        ) as rank
-    FROM sales_data
-),
-ranked_results AS (
-    SELECT 
-        category,
-        date,
-        amount,
-        running_total,
-        rank,
-        -- 新增分析维度
-        AVG(amount) OVER (
-            PARTITION BY category 
-            ORDER BY date 
-            ROWS 2 PRECEDING
-        ) as three_day_avg
-    FROM enriched_data
-)
-SELECT category, date, amount, running_total, rank, three_day_avg
-FROM ranked_results
-WHERE rank <= 10
-ORDER BY category, rank;
-```
-
-#### 2. JOIN操作优化转换
-
-```python
-# Spark广播JOIN
-from pyspark.sql.functions import broadcast
-
-result = large_df.join(
-    broadcast(small_df), 
-    large_df.customer_id == small_df.customer_id, 
-    "inner"
-)
-```
-
-**Lakehouse CTE优化版本**：
-
-```sql
--- CTE + MAPJOIN：性能与可读性双重优势
-WITH large_dataset AS (
-    SELECT customer_id, order_id, amount, order_date
-    FROM fact_orders
-    WHERE order_date >= '2024-01-01'
-),
-customer_dimension AS (
-    SELECT customer_id, customer_name, customer_tier, region
-    FROM dim_customers
-    WHERE status = 'Active'
-)
-SELECT /*+ MAPJOIN(customer_dimension) */
-    ld.order_id,
-    cd.customer_name,
-    cd.customer_tier,
-    cd.region,
-    ld.amount,
-    ld.order_date
-FROM large_dataset ld
-JOIN customer_dimension cd ON ld.customer_id = cd.customer_id
-ORDER BY ld.amount DESC;
-```
-
-### Spark UDF到SQL函数的转换
-
-```python
-# Spark自定义UDF
-from pyspark.sql.types import StringType
-
-def categorize_amount(amount):
-    if amount > 1000:
-        return "High"
-    elif amount > 500:
-        return "Medium"
-    else:
-        return "Low"
-
-categorize_udf = udf(categorize_amount, StringType())
-df_result = df.withColumn("amount_category", categorize_udf(col("amount")))
-```
-
-**Lakehouse CTE实现**：
-
-```sql
--- 内置CASE WHEN替代UDF：性能更优
-WITH categorized_orders AS (
-    SELECT 
-        order_id,
-        customer_id,
-        amount,
-        -- 内置逻辑替代UDF
-        CASE 
-            WHEN amount > 1000 THEN 'High'
-            WHEN amount > 500 THEN 'Medium'
-            ELSE 'Low'
-        END as amount_category,
-        -- 更丰富的分类逻辑
-        CASE 
-            WHEN amount > 1000 AND customer_tier = 'VIP' THEN 'Premium_High'
-            WHEN amount > 1000 THEN 'Standard_High'
-            WHEN amount > 500 THEN 'Medium'
-            ELSE 'Low'
-        END as detailed_category
-    FROM orders o
-    JOIN customers c ON o.customer_id = c.customer_id
-)
-SELECT 
-    amount_category,
-    detailed_category,
-    COUNT(*) as order_count,
-    AVG(amount) as avg_amount
-FROM categorized_orders
-GROUP BY amount_category, detailed_category
-ORDER BY avg_amount DESC;
-```

-## Hive用户迁移指南
-
-### MapReduce思维到现代分析的转换
-
-Hive用户习惯的多阶段Job执行模式在Lakehouse CTE中得到简化和性能提升：
-
-#### 1. 多阶段聚合的优化
-
-```sql
--- Hive多阶段思维（传统方式）
--- 第一阶段：基础聚合
-INSERT OVERWRITE TABLE temp_customer_summary
-SELECT customer_id, SUM(amount) as total_amount
-FROM orders
-WHERE dt = '2024-06-01'
-GROUP BY customer_id;
-
--- 第二阶段：二次聚合
-INSERT OVERWRITE TABLE final_customer_tiers
-SELECT 
-    CASE 
-        WHEN total_amount > 10000 THEN 'VIP'
-        ELSE 'Regular'
-    END as tier,
-    COUNT(*) as customer_count
-FROM temp_customer_summary
-GROUP BY CASE 
-    WHEN total_amount > 10000 THEN 'VIP'
-    ELSE 'Regular'
-END;
-```
-
-**Lakehouse CTE一体化实现**：
-
-```sql
--- 一体化CTE：消除中间表，提升性能
-WITH customer_totals AS (
-    -- 第一层聚合：对应Hive第一阶段
-    SELECT 
-        customer_id,
-        SUM(amount) as total_amount,
-        COUNT(*) as order_count
-    FROM orders
-    WHERE DATE_FORMAT(o.o_orderdate, 'yyyy-MM-dd') = '1995-01-01'  -- 模拟分区dt
-    GROUP BY customer_id
-),
-customer_tiers AS (
-    -- 客户分层：对应Hive第二阶段逻辑
-    SELECT

-        order_count,
-        CASE 
-            WHEN total_amount > 10000 THEN 'VIP'
-            WHEN total_amount > 5000 THEN 'Premium'
-            WHEN total_amount > 1000 THEN 'Standard'
-            ELSE 'Basic'
-        END as customer_tier
-    FROM customer_totals
-),
-tier_analysis AS (
-    -- 分层分析：扩展业务逻辑
-    SELECT 
-        customer_tier,
-        COUNT(*) as customer_count,
-        AVG(total_amount) as avg_amount,
-        SUM(total_amount) as tier_revenue,
-        AVG(order_count) as avg_orders_per_customer
-    FROM customer_tiers
-    GROUP BY customer_tier
-)
-SELECT 
-    customer_tier,
-    customer_count,
-    ROUND(avg_amount, 2) as avg_amount,
-    ROUND(tier_revenue, 2) as tier_revenue,
-    ROUND(avg_orders_per_customer, 2) as avg_orders,
-    -- 新增分析维度
-    ROUND(tier_revenue * 100.0 / SUM(tier_revenue) OVER (), 2) as revenue_percentage
-FROM tier_analysis
-ORDER BY tier_revenue DESC;
-```
-
-#### 2. 分区表处理优化
-
-```sql
--- Hive分区思维的延续与增强
-WITH partition_summary AS (
-    -- 分区数据聚合：保持Hive分区裁剪优势
-    SELECT

-        RANK() OVER (ORDER BY weekly_sales DESC) as global_rank,
-        -- 稳定性评分
-        CASE 
-            WHEN sales_stability / avg_daily_sales < 0.2 THEN 'Very Stable'
-            WHEN sales_stability / avg_daily_sales < 0.4 THEN 'Stable'
-            ELSE 'Volatile'
-        END as stability_rating
-    FROM weekly_trends

-## 性能优化最佳实践
-
-### 通用优化策略
-
-#### 1. CTE执行顺序优化
-
-```sql
--- 最佳实践：过滤 → 聚合 → 连接 → 计算
-WITH early_filtering AS (
-    -- 第一步：尽早过滤，减少数据量
-    SELECT customer_id, order_date, order_amount, product_id
-    FROM orders
-    WHERE order_date >= '2024-01-01'
-      AND order_status = 'completed'
-      AND order_amount > 100
-),
-aggregation_layer AS (
-    -- 第二步：聚合减少数据量
-    SELECT 
-        customer_id,
-        product_id,
-        COUNT(*) as order_count,
-        SUM(order_amount) as total_amount,
-        AVG(order_amount) as avg_amount
-    FROM early_filtering
-    GROUP BY customer_id, product_id
-),
-dimension_enrichment AS (
-    -- 第三步：与小表连接
-    SELECT /*+ MAPJOIN(customers, products) */
-        al.customer_id,

-        p.product_name,
-        p.category,
-        al.order_count,
-        al.total_amount,
-        al.avg_amount
-    FROM aggregation_layer al
-    JOIN customers c ON al.customer_id = c.customer_id
-    JOIN products p ON al.product_id = p.product_id
-),
-final_calculations AS (
-    -- 第四步：最终计算
-    SELECT 
-        *,
-        total_amount / SUM(total_amount) OVER (PARTITION BY customer_segment) as segment_share,
-        RANK() OVER (PARTITION BY category ORDER BY total_amount DESC) as category_rank
-    FROM dimension_enrichment
-)
-SELECT * FROM final_calculations
-WHERE category_rank <= 10
-ORDER BY total_amount DESC;
-```
-
-#### 2. 内存使用优化
-
-```sql
--- 避免大结果集的CTE
-WITH controlled_dataset AS (
-    -- 控制数据集大小
-    SELECT customer_id, order_amount, order_date
-    FROM orders
-    WHERE order_date >= '2024-06-01'  -- 限制时间窗口
-      AND customer_id IN (
-          SELECT customer_id 
-          FROM high_value_customers 
-          LIMIT 10000  -- 限制客户数量
-      )
-    LIMIT 100000  -- 限制总记录数
-),
-efficient_aggregation AS (
-    -- 高效聚合
-    SELECT 
-        DATE_FORMAT(order_date, 'yyyy-MM') as month,

-## 使用SQL任务计算新客户、活跃客户和流失客户
-
-在企业运营中，通常会基于用户行为特征将用户进行分层，针对不同分层的用户针对性的做一些运营动作，针对性的做用户转化。大多数场景下，会将用户划分为新客户、活跃客户以及流失用户。
-
-* 新用户：是指在特定时间段内新注册成为用户的数量，通常用于衡量用户增长的速度和吸引力。
-* 活跃用户：是指在特定时间段内有实际使用行为的用户数量，通常用于衡量用户参与度和留存情况。
-* 流失用户：是指在特定时间段内不在访问产品的用户。企业要尽可能减少流失用户的占比，减少唤起用户的成本。
-
-本教程中，我们将基于「电商数据集」，进行留存率的分析。所使用的数据来自云器Lakehouse的共享样例数据，可以直接按照如下方式直接使用:
-```
-select * from clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore limit 10;
-```
-
-### 第一步：根据每个客户的升序订单日期创建特定于每个客户 ID 的订单序列列。
-
-```SQL
-DROP TABLE if exists eCommerce_LifeCycle_Order_Sequence;
-CREATE TABLE eCommerce_LifeCycle_Order_Sequence 
-AS
-SELECT event_date,
-       user_id,
-       ROW_NUMBER() OVER (PARTITION BY user_id ORDER BY event_date ASC) AS customer_order_sequence,
-       LAG(event_date) OVER (PARTITION BY user_id ORDER BY user_id ASC) AS previous_order_date,
-       MIN(event_date) AS first_order_date,
-       MAX(event_date) AS last_order_date
-FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore
-WHERE event_type = 'purchase'
-GROUP BY event_date,
-         user_id;
-```
-
-### 第二步：创建一个新列，为客户 ID 插入先前的订单日期，以便在以后的代码块中用于计算订单之间的时间段
-
-```SQL
-DROP TABLE if exists eCommerce_LifeCycle_Time_Between_Orders;
-CREATE TABLE eCommerce_LifeCycle_Time_Between_Orders 
-AS
-SELECT event_date,
-       user_id,
-       customer_order_sequence,
-       CASE
-         WHEN previous_order_date IS NULL THEN event_date
-         ELSE previous_order_date
-       END AS previous_order_date,
-       DATEDIFF(event_date,previous_order_date) AS days_between_orders,
-       first_order_date,
-       last_order_date
-FROM eCommerce_LifeCycle_Order_Sequence;
-```
-
-### 第三步：使用CASE 语句创建一个附加的 customer\_life\_cycle 列，以根据 days\_between\_orders 列指示订单是来自新客户、活跃客户还是已失效客户。在此示例中，如果订单发生在距上一个订单 1 到 365 天之间的任何时间，则客户被视为活跃客户；如果先前订单超过 365 天，则客户被视为已失效。
-
-```SQL
-DROP TABLE if exists eCommerce_LifeCycle;
-CREATE TABLE eCommerce_LifeCycle 
-AS
-SELECT event_date,
-       user_id,
-       CASE
-         WHEN customer_order_sequence = 1 THEN '新客户'
-         WHEN days_between_orders > 0 AND days_between_orders < 30 THEN '活跃客户'
-         WHEN days_between_orders > 30 THEN '沉睡客户'
-         ELSE '未知'
-       END AS customer_life_cycle,
-       customer_order_sequence,
-       previous_order_date,
-       CASE
-         WHEN days_between_orders IS NULL THEN 0
-         ELSE days_between_orders
-       END AS days_between_orders,
-       first_order_date,
-       last_order_date
-FROM eCommerce_LifeCycle_Time_Between_Orders;

-# STRING 类型
-
-`STRING` 类型用于表示长度大于或等于 0 的所有字符序列。该类型可以存储最大为 16MB 的文本数据。在批量、实时导入数据时，会对字段进行长度校验。如果您在导入数据时遇到超过16MB的数据，可以通过修改表的属性来调整字符串长度的限制，例如将 `STRING` 长度设置为32MB：
-
-```
-ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.string.bytes"="33554432");
-```
-
-## 语法
-
-```
-[r]'c [ ... ]'
-```
-
-- `r`：可选前缀，表示字符串中的转义字符不会被转义。这对于包含特殊字符的字符串非常有用，因为它允许字符串按原样被解释，而不是被转换成转义序列。
-- `c`：Unicode 字符集中的任意字符。
-
-## 转义序列
-
-在常规字符串文本（无 `r` 前缀）中，以下转义序列会被识别，并根据以下规则替换：
-
-- `\0` -> `\u0000`，具有代码 0 的 Unicode 字符；
-- `\b` -> `\u0008`，退格键；
-- `\n` -> `\u000a`，换行符；
-- `\r` -> `\u000d`，回车符；
-- `\t` -> `\u0009`，水平制表符；
-- `\Z` -> `\u001A`，替换；
-- `\%` -> `\%`；
-- `\_` -> `\_`；
-- `\<other char>` -> `<other char>`，跳过斜杠并保留字符原样。
-
-如果字符串具有前缀 `r`，则不会识别这些转义序列。
-
-## 示例
-
-以下是一些使用 `STRING` 类型和转义序列的示例：
-
-```
--- 未添加 r，转义序列被解释
-SELECT 'Hello \n World!' AS col;
-+---------+
-|   col   |
-+---------+
-| Hello 
- World! |
-+---------+
-
--- 添加 r，转义序列不被解释
-SELECT r'Hello \n World!' AS col;
-+-----------------+
-|       col       |
-+-----------------+
-| Hello \n World! |
-+-----------------+
-
--- 使用空字符串
-SELECT '' AS col;
-+-----+
-| col |
-+-----+
-|     |
-+-----+
-
--- 使用反斜杠
-SELECT '\\' AS col;
-+-----+
-| col |
-+-----+
-| \   |
-+-----+
-
--- 使用 r 前缀，反斜杠不被转义
-SELECT r'\\' AS col;
-+-----+
-| col |
-+-----+
-| \\  |

-# STRUCT
-
-`STRUCT` 函数用于创建一个结构体，它可以包含多个不同类型的值。结构体的组成通过一系列字段名和对应的数据类型来描述。结构体在处理复杂数据时非常有用，可以方便地将多个相关数据组织在一起。
-
-## 语法
-
-```
-STRUCT<field1_name: field1_type, field2_name: field2_type, …>
-```
-
-## 示例
-
-1. 创建一个包含公司名称和员工数量的结构体：
-    ```
-   CREATE TABLE TABLE_STRUCT(col struct<company_name:string,employee_count:int>)
-    ```
-
-2. 使用 `named_struct` 函数创建一个具有明确字段名的结构体：
-
-   ```
-   SELECT named_struct('company_name', 'ClickZetta', 'employee_count', 5);
-   ```
-
-
-3. 在查询中使用结构体并结合其他字段：
-
-   ```
-   SELECT
-    col.company_name,
-    col.employee_count,
-   FROM TABLE_STRUCT;

-# 云器 Lakehouse 权限体系盘点与优化最佳实践指南
-
-## 文档信息
-- **目标读者**：系统管理员、安全管理员、数据治理团
-
----
-
-## 一、概述
-
-在云器 Lakehouse 中，用户和角色是重要的数字资产。随着业务发展，权限体系可能变得复杂，出现权限冗余、角色闲置等问题。本指南将帮助您：
-
-- ✅ 理解云器 Lakehouse 的双层权限体系
-- ✅ 掌握通过 Studio Web 界面和 SQL 进行权限管理
-- ✅ 区分空间级和实例级两种权限盘点视角
-- ✅ 识别和清理权限冗余
-- ✅ 建立持续的权限治理机制
-
-## 二、理解云器 Lakehouse 权限体系
-
-### 2.1 双层权限架构
-
-云器 Lakehouse 采用**实例-空间**双层权限体系：
-
-```
-云器 Lakehouse Instance（实例）
-├── 实例级资源
-│   ├── Instance Users（实例用户池）
-│   │   ├── 普通用户（从全局平台同步）
-│   │   └── 服务用户（API/自动化使用）
-│   └── Instance Roles（实例级角色）
-│       ├── instance_admin（实例管理员）
-│       ├── instance_sre（实例运维）
-│       ├── instance_datasource_admin（数据源管理）
-│       └── ...其他实例级角色
-│
-└── 工作空间层
-    ├── Workspace A（工作空间A）
-    │   ├── Workspace Users（从实例用户池授权的用户）
-    │   └── Workspace Roles（空间级角色）
-    │       ├── workspace_admin
-    │       ├── workspace_dev
-    │       └── 自定义角色
-    ├── Workspace B
-    │   ├── Workspace Users
-    │   └── Workspace Roles
-    └── Workspace C
-        ├── Workspace Users
-        └── Workspace Roles
-```
-
-**关键理解**：
-- 用户首先存在于实例级用户池中
-- 通过 `CREATE USER` 命令将实例用户添加到特定工作空间
-- 实例级角色具有跨工作空间的权限
-- 工作空间级角色仅在特定工作空间内有效
-
-### 2.2 角色类型分类
-
-| 角色类型 | 作用范围 | 分配位置 | 示例 | 说明 |
-|---------|---------|---------|------|------|
-| **实例级角色** | 跨所有 Workspace | 实例层面分配 | `instance_admin`<br>`system_admin`<br>`instance_sre`<br>`instance_datasource_admin` | 拥有跨工作空间的管理权限<br>在实例级别统一管理 |
-| **空间级系统角色** | 单一 Workspace | 工作空间内分配 | `workspace_admin`<br>`workspace_dev`<br>`workspace_analyst`<br>`workspace_sre`<br>`workspace_user` | 系统预置，权限范围限于特定工作空间<br>每个工作空间独立管理 |
-| **空间级自定义角色** | 单一 Workspace | 工作空间内创建和分配 | 用户自定义角色名 | 根据业务需求创建<br>仅在创建它的工作空间内有效 |
-
-> **重要说明**：
-> - 系统预置角色中，`workspace_admin` 和 `instance_admin` 的权限不可修改
-> - 其他预置角色的权限可以根据需要进行调整
-> - 目前仅支持在工作空间内创建自定义角色，不支持创建实例级自定义角色
-
-### 2.3 用户管理流程
-
-理解用户在云器 Lakehouse 中的流转过程：
-
-```
-1. 全局平台用户（在 accounts.yunqi.com 注册）
-         ↓ 自动同步
-2. 实例用户池（存在于 Lakehouse 实例中）
-         ↓ CREATE USER 命令
-3. 工作空间用户（被授权访问特定工作空间）
-         ↓ GRANT ROLE 命令
-4. 拥有角色的用户（具有实际操作权限）
-```
-
-> **重要概念**：在工作空间中执行 `CREATE USER` 实际上是将已存在于实例用户池的用户添加到当前工作空间，这就是为什么不需要指定密码的原因。
-
-### 2.4 角色权限范围说明
-
-> **注意**：
-> - 不同角色之间的权限继承关系需要根据实际环境验证，不同版本可能有所差异
-> - `system_admin` 角色即将下线，建议使用 `instance_admin` 作为实例级管理角色
-> - 建议通过实际测试确认各角色的具体权限范围
-
-## 三、🔍 关键概念：两种盘点视角（必读）
-
-### 3.1 空间级盘点 vs 实例级盘点
-
-| 对比维度 | 📁 空间级盘点 | 🌐 实例级盘点 |
-|---------|--------------|--------------|
-| **数据来源** | information_schema（已过滤） | 全局元数据（需特殊权限） |
-| **SQL 过滤条件** | `WHERE workspace_id = current_workspace_id()` | 无过滤，可见所有数据 |
-| **可见范围** | 仅当前工作空间 | 所有工作空间 |
-| **适用场景** | 日常权限管理 | 全局安全审计 |
-| **局限性** | ❌ 无法看到其他工作空间<br>❌ 可能误判权限冗余 | ❌ 需要高级权限<br>❌ 操作复杂度高 |
-
-### 3.2 重要提示
-
-> ⚠️ **关键区别**：
-> - 使用 `information_schema` 进行的盘点都是**空间级盘点**，只能看到当前工作空间的"局部视图"
-> - 要进行实例级盘点，需要通过 Studio 管理控制台或特殊权限访问全局数据
-> - 判断方法：如果您的查询基于 `information_schema` 表，那么您正在进行空间级盘点
-
-## 五、权限盘点实践步骤
-
-### 步骤 1：明确盘点级别
-
-```sql
--- 确认当前盘点环境和级别
-SELECT 
-    '当前盘点级别' as check_item,
-    '空间级盘点' as level,
-    current_workspace() as workspace_scope,
-    '仅可见当前工作空间数据' as visibility_limit,
-    '如需全局视图请使用管理控制台' as suggestion;
-```
-
-### 步骤 2：用户角色分布分析
-
-```sql
--- 分析用户的角色分配情况（已脱敏）
-SELECT 
-    CASE 
-        WHEN user_name LIKE 'admin%' THEN 'admin_user_' || ROW_NUMBER() OVER (ORDER BY user_name)
-        WHEN user_name LIKE 'dev%' THEN 'dev_user_' || ROW_NUMBER() OVER (ORDER BY user_name)
-        ELSE 'user_' || ROW_NUMBER() OVER (ORDER BY user_name)
-    END as masked_user,
-    role_names,
-    LENGTH(role_names) - LENGTH(REPLACE(role_names, ',', '')) + 1 as role_count,
-    CASE 
-        WHEN role_names LIKE '%system_admin%' THEN '包含实例级角色'
-        WHEN role_names LIKE '%workspace_admin%' THEN '空间管理员'
-        WHEN role_names LIKE '%workspace_dev%' THEN '开发人员'
-        ELSE '普通用户'
-    END as user_category
-FROM information_schema.users
-ORDER BY role_count DESC;
-```
-
-### 步骤 3：角色使用情况分析
-
-```sql
--- 分析角色的分配和使用情况
-SELECT 
-    role_name,
-    CASE 
-        WHEN role_name LIKE 'instance_%' THEN '实例级角色（在空间级视图中）'
-        WHEN role_name = 'system_admin' THEN '实例级角色（即将下线）'
-        WHEN role_name LIKE 'workspace_%' THEN '空间级-系统预置'
-        ELSE '空间级-自定义'
-    END as role_classification,
-    CASE 
-        WHEN user_names IS NULL OR user_names = '' THEN '⚠️ 未分配'
-        ELSE '✅ 已分配'
-    END as assignment_status,
-    CASE 
-        WHEN user_names IS NOT NULL THEN 
-            LENGTH(user_names) - LENGTH(REPLACE(user_names, ',', '')) + 1
-        ELSE 0
-    END as assigned_user_count,
-    comment as description
-FROM information_schema.roles
-ORDER BY 
-    CASE WHEN user_names IS NULL THEN 0 ELSE 1 END DESC,
-    role_name;
-```
-
-> **注意**：虽然 `instance_admin` 等是实例级角色，但它们也会出现在空间级的 `information_schema.roles` 视图中，这是因为这些角色在当前工作空间中有用户被授予了该角色。
-
-### 步骤 4：权限冗余检测
-
-```sql
--- 检测潜在的权限冗余（需验证角色间是否真的存在继承关系）
-WITH permission_check AS (
-    SELECT 
-        CASE 
-            WHEN user_name LIKE 'admin%' THEN 'admin_user'
-            WHEN user_name LIKE 'dev%' THEN 'dev_user'
-            ELSE 'regular_user'
-        END as user_type,
-        role_names,
-        CASE 
-            WHEN role_names LIKE '%system_admin%' 
-                 AND role_names LIKE '%workspace_%'
-            THEN '可能存在跨级别冗余（需验证）'
-            WHEN role_names LIKE '%workspace_admin%' 
-                 AND role_names LIKE '%workspace_user%'
-            THEN '可能存在同级别冗余（需验证）'
-            ELSE '表面无冗余'
-        END as redundancy_check,
-        '建议：实际测试各角色权限以确认是否真的冗余' as action_needed
-    FROM information_schema.users
-)
-SELECT * FROM permission_check
-WHERE redundancy_check != '表面无冗余';
-```
-
-### 步骤 5：生成盘点报告
-
-```sql
--- 生成空间级权限盘点摘要
-WITH summary AS (
-    SELECT 
-        COUNT(DISTINCT user_name) as total_users,
-        COUNT(DISTINCT role_name) as total_roles,
-        SUM(CASE WHEN user_names IS NOT NULL THEN 1 ELSE 0 END) as assigned_roles,
-        SUM(CASE WHEN user_names IS NULL THEN 1 ELSE 0 END) as unassigned_roles
-    FROM information_schema.users
-    CROSS JOIN information_schema.roles
-)
-SELECT 
-    '===== 空间级权限盘点报告 =====' as report_header,
-    current_workspace() as workspace_name,
-    total_users || ' 个用户' as user_summary,
-    total_roles || ' 个角色（' || assigned_roles || ' 已分配，' || unassigned_roles || ' 未分配）' as role_summary,
-    ROUND(assigned_roles * 100.0 / total_roles, 1) || '%' as role_utilization,
-    '注意：本报告仅包含当前工作空间数据' as important_notice
-FROM summary;
-```
-
-## 六、最佳实践建议
-
-### 6.1 分级权限管理策略
-
-#### 📁 空间级管理（日常操作）
-- **频率**：每月执行
-- **范围**：当前工作空间
-- **重点**：
-  - 清理空间内明显的角色冗余
-  - 处理长期未分配的自定义角色
-  - 优化空间内用户的角色组合
-
-#### 🌐 实例级管理（定期审计）
-- **频率**：每季度执行
-- **范围**：所有工作空间
-- **重点**：
-  - 审核 system_admin 的全局分配
-  - 检查跨空间的权限一致性
-  - 识别跨空间的账号重复
-
-### 6.2 权限分配决策树
-
-```
-用户需要跨工作空间管理？
-├─ 是 → 考虑分配 system_admin（需实例级审批）
-└─ 否 → 仅在当前工作空间分配角色
-        │
-        需要管理工作空间？
-        ├─ 是 → 分配 workspace_admin
-        └─ 否 → 需要开发权限？
-                ├─ 是 → 分配 workspace_dev
-                └─ 否 → 分配 workspace_user 或其他角色
-```
-
-### 6.3 避免常见误区
-
-| 误区 | 正确做法 |
-|------|----------|
-| 认为用户只存在于工作空间中 | 理解用户首先存在于实例用户池，然后被添加到工作空间 |
-| 仅凭空间级视图判断实例级角色冗余 | 需要实例级视图确认其全局使用情况 |
-| 假设角色间一定存在继承关系 | 实际测试验证各角色的具体权限 |
-| 一次性删除所有未使用角色 | 先了解角色用途，分批处理 |
-| 混淆实例级和空间级角色的管理位置 | 实例级角色在实例层面管理，空间级角色在工作空间内管理 |
-| 在 SQL 中使用已废弃的角色 | 使用 `instance_admin` 替代即将下线的 `system_admin` |
-
-### 6.4 管理工具选择建议
-
-| 管理任务 | 推荐工具 | 原因 |
-|---------|---------|------|
-| 日常用户授权 | Studio Web 界面 | 操作直观，不易出错 |
-| 批量权限变更 | SQL 脚本 | 效率高，可重复执行 |
-| 权限审计报表 | SQL 查询 + Studio | 结合使用效果最佳 |
-| 实例级管理 | Studio 管理控制台 | 可视化全局视图 |
-| 自动化监控 | API + SQL | 适合集成到监控系统 |
-
-### 6.5 监控指标建议
-
-1. **空间级指标**（可直接监控）
-   - 角色使用率 = 已分配角色数 / 空间内总角色数
-   - 用户平均角色数 = 总角色分配数 / 用户数
-   - 自定义角色占比 = 自定义角色数 / 总角色数
-
-2. **实例级指标**（需要全局权限）
-   - system_admin 分布 = 各空间 system_admin 用户数
-   - 跨空间用户重复率 = 重复用户数 / 总用户数
-   - 全局角色标准化程度 = 使用系统角色的空间数 / 总空间数
-
-## 七、自动化与持续改进
-
-### 7.1 创建监控视图
-
-```sql
--- 创建空间级权限监控视图
-CREATE  VIEW workspace_permission_monitor AS
-SELECT 
-    current_date() as monitor_date,
-    current_workspace() as workspace,
-    '空间级监控' as monitor_level,
-    COUNT(DISTINCT u.user_name) as user_count,
-    COUNT(DISTINCT r.role_name) as role_count,
-    SUM(CASE WHEN r.user_names IS NOT NULL THEN 1 ELSE 0 END) as active_roles,
-    ROUND(
-        SUM(CASE WHEN r.user_names IS NOT NULL THEN 1 ELSE 0 END) * 100.0 / 
-        COUNT(DISTINCT r.role_name), 
-        1
-    ) as role_usage_percentage,
-    COUNT(DISTINCT CASE WHEN u.role_names LIKE '%system_admin%' THEN u.user_name END) as admin_users
-FROM information_schema.users u
-CROSS JOIN information_schema.roles r
-GROUP BY workspace;
-```
-
-### 7.2 定期检查脚本
-
-```sql
--- 每月执行的权限健康检查
-WITH health_check AS (
-    -- 检查1: 未使用的角色
-    SELECT 
-        'unused_roles' as check_type,
-        COUNT(*) as issue_count,
-        '存在未分配的角色' as description
-    FROM information_schema.roles
-    WHERE user_names IS NULL OR user_names = ''
-

-# 通过流、管道和SQL任务在 Lakehouse 上实现数仓缓慢变化维SCD
-
-## 关于SCD
-
-缓慢变化维 (Slowly Changing Dimensions, SCD) 是数据仓库设计中的一个关键概念，用于处理维度表中的数据在随时间变化时的管理。维度表包含描述性数据，例如客户信息、产品信息等，而这些信息可能会随时间发生变化。SCD提供了一种方法来处理和记录这些变化，以便数据仓库中的历史数据和当前数据都能保持一致和准确。
-
-SCD通常分为几种类型：
-
-### SCD 类型 1
-
-SCD 类型 1 通过覆盖旧数据来处理变化。这意味着当维度数据发生变化时，旧的数据将被新数据覆盖，因此不会保留历史记录。这种方法简单且快速，但会丢失历史数据。
-
-**示例**：假设客户的地址发生了变化，SCD 类型 1 将直接更新客户地址字段，旧的地址信息将被新地址覆盖。
-
-### SCD 类型 2
-
-SCD 类型 2 通过创建新行来处理变化，以保留历史记录。这种方法在维度表中添加一个新的记录，并且用新数据更新它，同时保留旧数据行，并可能使用有效日期列或版本列来跟踪不同版本的数据。
-
-**示例**：当客户的地址发生变化时，SCD 类型 2 将在维度表中插入一条新的记录，包含新地址，并可能添加一个有效日期范围来表示该地址的有效期。
-
-### SCD 类型 3
-
-SCD 类型 3 通过在表中添加额外的列来处理变化，以保留有限的历史记录。这种方法在维度表中添加一个新列来存储旧数据，当变化发生时，旧数据移到新列，新数据覆盖原来的位置。
-
-**示例**：如果客户的地址变化，SCD 类型 3 会在表中添加一个“旧地址”列，将旧地址存储到该列中，新地址存储在原始列中。

-
-^
-
-### 管道概述
-
-自动捕获和处理数据变化的端到端数据管道：
-
-1. **数据源**（Jupyter 调用 Fake 生成测试数据）**→** 使用 Python 创建数据来模拟现实世界事件。
-2. [Zettapark](ZettaparkQuickStart.md) **PUT**→ 使用Zettapark将数据拉取并加载到 数据湖Volume上。
-3. [数据湖Volume](datalake_volume.md) → 基于阿里云OSS的数据湖存储。
-4. [Lakehouse Pipe](pipe-summary.md)**捕捉数据湖文件变化**→ Lakehouse Pipe 高效地将数据从数据湖Volume流式传输到 Lakehouse。
-5. [Lakehouse Table Stream](table_stream.md)**捕捉Table数据变化**→ 捕捉基表里的变化数据供增量消费。
-6. **SQL**[任务](ide.md)**进行SCD处理 →** 通过开发SQL任务实现SCD的处理逻辑，并通过云器Lakehouse Studio实现任务调度。
-7. **Lakehouse数据管理**，Lakehouse 通过三个表管理数据：
-
-   * `customer_raw`：存储原始摄取数据。
-   * `customer`：反映流管道的最新更新。
-   * `customer_history`：保留所有更新的记录以供分析和审计变化历史。
-
-## 关键组件
-
-### 数据生成
-
-* **使用的工具**： Python
-* Python 脚本动态生成模拟客户数据以模拟实时数据源。

-
-* **Pipe**：Lakehouse内置的实时数据提取服务，使用 Pipe 进行实时流式传输
-
-  * 自动检测 数据湖Volume 中的新文件
-  * 无需人工干预即可将数据加载到临时表customer\_raw中
-
-### 变化检测层
-
-* **Lakehouse 流（Table Stream）**：
-
-  * 捕获 INSERT、UPDATE、DELETE 等操作
-  * 维护变更跟踪元数据
-  * 能够高效处理增量变更

-### 监控和维护
-
-#### Pipe监控
-
-* 使用SHOW PIPES命令查看PIPE对象列表
-
-```SQL
-SHOW PIPES;
-```
-
-* 使用DESC PIPE命令查看指定PIPE对象详细信息
-
-```SQL
-DESC PIPE volume_pipe_cdc_demo;
-```
-
-:-: ![](.topwrite/assets/image_1736483133453.png =562)
-
-* 查看pipe copy作业执行情况
-
-通过作业历史中的query\_tag来筛选,所有的pipe执行的copy作业都会在query\_tag打上标签:格式为pipe.worksapce\_name.schema\_name.pipe\_name
-
-本指南worksapce\_name是ql\_ws，schema\_name是SCD\_SCH，pipe name是volume\_pipe\_cdc\_demo，因此query\_tag是：
-
-pipe.ql\_ws.scd\_sch.volume\_pipe\_cdc\_demo
-
-导航到计算->作业历史：

-## 概述
-
-Lakehouse 提供了标准的 Apache Iceberg Catalog REST API 接口，允许外部计算引擎（如 Apache Spark）通过统一的 REST 协议访问和查询存储在 Lakehouse 数据湖（如对象存储 OSS）中的 Iceberg 表。这使得在保持数据统一存储的同时，能够灵活选择不同的计算引擎进行数据分析。
-
-## 核心特性
-
-* **标准兼容**：兼容 Apache Iceberg REST Catalog 规范
-* **引擎支持**：支持 Spark 计算引擎
-* **权限委托**：通过 vended-credentials 模式管理存储访问权限
-* **多云支持**：支持阿里云 OSS（后续版本支持 AWS S3、腾讯云 COS 等）
-
-## 使用限制
-
-**数据类型兼容性**
-
-当通过 Spark 引擎访问 ClickZetta Lakehouse 表时，存在以下数据类型限制：
-
-暂不支持的数据类型：
-
-* **整数类型**：`SMALLINT`, `TINYINT`
-* **半结构化类型**：`JSON`
-* **向量类型**：`VECTOR`
-
-## 快速开始
-
-### 前置要求
-
-1. 云器 Lakehouse 实例的账号和密码
-
-2. 目标计算引擎环境：Spark 3.5+
-
-3. 必要的依赖包：
-
-   1. Apache Iceberg 库（Scala 2.12 / Spark 3.5.x）`：org.apache.iceberg:iceberg-spark-runtime-3.5_2.12:1.6.1`
-
-   2. 对应云对象存储的 SDK（如阿里云 OSS：`com.aliyun.oss:aliyun-sdk-oss:3.18.1`）
-
-### PySpark 集成示例
-
-#### 环境准备
-
-```Python
-import os
-import base64
-from pyspark.sql import SparkSession
-# 设置 SPARK_HOME 环境变量（根据实际安装路径调整）
-os.environ['SPARK_HOME'] = '/path/to/pyspark'
-```
-
-连接云器 Lakehouse 的认证配置
-
-```Python
-# 配置认证信息
-username = "your_username"
-password = "your_password"
-
-# 生成 Basic Authentication header
-credentials = f"{username}:{password}"
-encoded_bytes = base64.b64encode(credentials.encode("utf-8"))
-encoded_str = encoded_bytes.decode("utf-8")
-auth_header = f"Basic {encoded_str}"
-```
-
-创建 Spark Session
-
-```Python
-spark = SparkSession.builder \
-    .appName('IcebergCatalogIntegration') \
-    .config("spark.jars.packages", "org.apache.iceberg:iceberg-spark-runtime-3.5_2.12:1.6.1," + "com.aliyun.oss:aliyun-sdk-oss:3.18.1") \
-    .config('spark.sql.extensions', 'org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions') \
-    .config('spark.sql.defaultCatalog', 'clickzetta_catalog') \
-    .config('spark.sql.catalog.clickzetta_catalog', 'org.apache.iceberg.spark.SparkCatalog') \
-    .config('spark.sql.catalog.clickzetta_catalog.type', 'rest') \
-    .config("spark.sql.catalog.clickzetta_catalog.header.instanceName", "your_instance_id") \
-    .config("spark.sql.catalog.clickzetta_catalog.header.Workspace", "your_workspace") \
-    .config('spark.sql.catalog.clickzetta_catalog.uri','https://api.clickzetta.com/api/v1/catalog/iceberg-rest') \
-    .config("spark.sql.catalog.clickzetta_catalog.header.Authorization", auth_header) \
-    .config("spark.sql.catalog.clickzetta_catalog.io-impl", "org.apache.iceberg.aliyun.oss.OSSFileIO") \
-    .config("spark.sql.catalog.clickzetta_catalog.oss.endpoint", "oss-cn-hangzhou.aliyuncs.com") \
-    .config('spark.sql.catalog.clickzetta_catalog.header.X-Iceberg-Access-Delegation','vended-credentials') \
-    .config("spark.sql.catalog.clickzetta_catalog.default-namespace", "public") \
-    .config("spark.sql.catalog.clickzetta_catalog.metrics-reporter-impl", "org.apache.iceberg.metrics.LoggingMetricsReporter") \
-    .getOrCreate()
-```
-
-使用示例
-
-```Python
-# 查看所有命名空间（schemas）
-spark.sql("SHOW NAMESPACES IN clickzetta_catalog").show()
-
-# 查看指定命名空间中的表
-spark.sql("SHOW TABLES IN clickzetta_catalog.public").show()
-
-# 查看表结构
-spark.sql("DESCRIBE TABLE clickzetta_catalog.public.your_table").show()
-
-# 查询数据
-df = spark.sql("SELECT * FROM clickzetta_catalog.public.your_table LIMIT 10")df.show()
-
-# 使用 DataFrame API
-table_df = spark.table("clickzetta_catalog.public.your_table")
-table_df.filter("column_name > 100").select("col1", "col2").show()
-```

-# 通过Private Link和SSH结合来同步VPC内的RDS数据
-
-## 1. 适用场景
-
-Lakehouse Studio **数据集成** 通过 VPC 网络同步 RDS 的数据，可解决公网传输带来的如下问题：
-
-* 数据延迟高
-* 公网流量成本高
-* 不安全/不合规
-
-## 2. 历史方案优缺点总结
-
-* **纯 Private Link 方案**：不支持连接 RDS 实例，只支持 ECS 上自建的 MySQL。
-* **VPC Peering 验证走通**：但是会暴露双方内网环境，有安全风险，不建议使用。
-* **通过 IGS SDK**：通过 Private Link 支持把数据推送到 Lakehouse，但是导入调度策略需要客户自己负责，无法集成到 workflow 中。
-* **纯 SSH TUNNEL**：中间一段需要走公网，能解决 RDS 暴露公网的安全问题，但是不能解决公网流量问题。
-
-## 3. 本方案简介
-
-本方案是 Private Link 与 SSH Tunnel 两种方式相结合的方案。
-
-网络架构图（以阿里云上为例）：
-
-![](.topwrite/assets/whiteboard_exported_image.png)
-
-（客户环境也可在同 Region 的其他可用区）
-
-默认由**终端节点**侧承担开销，计费项有两个，具体可参考 [计费规则](https://help.aliyun.com/document_detail/198081.html?spm=a2c4g.120462.0.0.462f29e3tnGfMO#section-4zx-gat-sg7)。
-
-## 4. 配置方法（示例）：
-
-### Step1：环境准备
-
-**客户侧环境**：
-
-* VPC：杭州 H：专有网络 **VPC\_Customr**: [vpc-bp1qmyayneio4mlyoyeb7](https://vpc.console.aliyun.com/vpc/cn-hangzhou/vpcs/vpc-bp1qmyayneio4mlyoyeb7?type=base)，网段: `172.16.0.0/12`
-* RDS：杭州 H：私网地址：\`\` （`rm-bp15gq963ic327h8f.mysql.rds.aliyuncs.com`）
-* ECS：杭州 H：私网 IP 地址 `172.16.12.182`
-
-**Lakehouse 侧**：
-
-CZ Studio UAT 环境数据集成 EMR 集群所在 VPC 和 VWS：杭州 H
-
-| SQL vpc-bp1jvn\*\*\*\*\*\*\*\*\*\*\*u  vsw-bp1rp\*\*\*\*\*\*\*\*\*\*\*\*cii |
-| --------------------------------------------------------------------------- |
-
-CZ UAT 环境阿里云主账号：`138************83`
-
-### Step 2：在 ECS 上创建 SSH 端口转发
-
-在客户网络环境中，创建一台与 RDS 互通的 ECS，在此机器上创建端口转发：访问该 ECS 的 12345 端口，会被转发到 RDS 的 3306 端口。
-
-```Shell
-ssh -CfNg -L 12345:rm-bp15gq963ic327h8f.mysql.rds.aliyuncs.com:3306 root@127.0.0.1 -p22
-
-##验证：

-
-***
-
-### Step 3：创建负载均衡 CLB
-
-* 进入负载均衡 SLB 控制台 -> 左侧 **传统型负载均衡 CLB（原 SLB）** -> **创建传统型负载均衡**
-
-* 创建监听如下：
-  ![](.topwrite/assets/c417a0f96d/c4ec47d374f0564f96375d460e06a2b096c64688.png)
-
-* 在标签页 **默认服务器组** 中添加 Step 2 中的 ECS，前端端口为 22（自定义），后端端口为转发到 RDS 的端口，本案例中为 12345。
-
-### Step 4：客户侧：创建终端节点服务
-
-* 进入 VPC 控制台，选择与 CZ 数据集成集群相同的 Region，左侧 **终端节点服务** -> **创建终端节点服务**
-* **服务资源类型 -> 传统型负载均衡 CLB**（与 Step1 一致），选择可用区 \*\*杭州 可用区H，\*\*在下拉框中选择 step1 中创建的 CLB 实例，自动接收端点连接：是，其它默认
-* 进入该终端节点服务：在 **服务白名单** 中，添加云器环境主账号：`1384322691904283`
-
-  ![](.topwrite/assets/c417a0f96d/fc469bdcdf20cda3bca8b56dfa9d4b66b010e090.png)
-
-### Step 5：Lakehouse 侧创建终端节点
-
-* 进入 VPC 控制台，选择与 CZ 数据集成集群相同的 Region，在左侧菜单中选择 **终端节点**。
-* 在终端节点页面，系统会自动发现 Step 4 中创建的终端节点服务，选择对应的 **专有网络** 后，确认创建；
-* 在客户侧和 Lakehouse 侧的**终端节点服务**和**终端节点**的**终端节点连接**信息中，可以获取域名。
-
-### **验证**：
-
-**Lakehouse Studio 数据集成**：
-
-在数据源配置中，使用如下 JDBC URL：`jdbc:mysql://ep-bp1iabb21a27719ca8a2-cn-hangzhou-h.epsrv-bp1n7rvc8qbpudxk69fr.cn-hangzhou.privatelink.aliyuncs.com:22/mysql`

-# Table（表）
-
-在云器Lakehouse中，Table（表）是存储数据的基本单位，它是数据库中组织数据的核心结构。Lakehouse 的表设计为列式存储，这种存储方式在处理分析型查询时表现出极高的效率，因为它允许查询只读取需要的列数据，而不是整行数据。这种存储结构特别适合于数据仓库和大数据分析场景，可以显著提高数据处理的速度。
-
-## 表的约束
-
-表的约束用于确保表中数据的完整性和准确性。在Lakehouse中，支持多种类型的约束，包括但不限于：
-
-### NOT NULL
-
-**NOT NULL** 约束确保列中的值不能为NULL。这是在创建表时设置的，一旦设置，该约束将不可去除，以确保列中始终有有效数据。
-
-### PRIMARY KEY
-
-**主键（PRIMARY KEY）** 用于确保表中每条记录的唯一性。在大数据场景下，由于数据量通常非常庞大，为了保证数据的唯一性而对所有 key 进行逐一检查是不现实且低效的，因此一般不推荐在大数据环境中使用主键约束。然而，Lakehouse 仍提供了对主键的支持，以便在特定场景下满足数据完整性的需求。在 Lakehouse 架构中，定义了主键的表在进行实时数据写入时，系统将自动根据主键值进行数据去重，这对于变更数据捕获（CDC）场景尤为重要。例如，您可以实时地将MySQL数据库的binlog日志同步到Lakehouse，确保数据的一致性。设置完主键后，需要通过 [实时数据接口](java_reference/realtime-upload.md) 来处理数据。在 CDC 实时写入过程中，系统将依据主键自动进行数据去重，以维护数据的准确性和完整性。
-
-#### Lakehouse 主键支持及默认行为
-
-Lakehouse 支持两种直接指定主键（primary key）的方式，且在默认情况下，其行为设置为 `ENABLE VALIDATE RELY`。这意味着，当您在创建表时指定了主键，并且没有特别指定其他行为时，系统会自动启用对主键的验证和依赖关系。
-
-在这种默认行为下，无论是实时写入操作还是通过 SQL 进行的数据写入，系统都会依据所定义的主键进行去重处理。如果尝试插入与现有主键值重复的记录，系统将拒绝执行该插入操作，以确保主键的唯一性。例如：
-
-```sql
-create table test_primary(id int primary key,name string);
-desc extended test_primary;
-insert into test_primary values(1,"1");
-insert into test_primary values(2,"1");
--- 此时插入成功，因为主键值 1 和 2 均未重复
-insert into test_primary values(1,"1");
--- 插入失败，因为主键值 1 已存在
-select * from test_primary;
-```
-
-从上述示例可以看出，在默认的 `ENABLE VALIDATE RELY` 模式下，系统严格维护主键的唯一性，无论是单条记录插入还是批量插入，都会进行主键冲突检查。
-
-#### 自定义主键行为
-
-如果您根据实际业务需求，希望在插入数据时仅由实时写入机制进行主键去重，而通过 SQL 写入时则不执行去重操作，可以通过将主键行为设置为 `disable NOVALIDATE RELY` 来实现。以下是具体的操作示例：
-
-```sql
-create table test_primary_di(id int primary key disable NOVALIDATE RELY ,name string);
-insert into test_primary_di values(1,"1");
-insert into test_primary_di values(2,"1");
--- 此时插入成功，主键检查按预期执行
-insert into test_primary_di values(1,"1");
--- 插入成功，因为在 disable NOVALIDATE RELY 模式下，SQL 写入不进行主键去重
-```
-
-需要注意的是，在 `disable NOVALIDATE RELY` 模式下，虽然实时写入仍会依据主键进行去重，但通过 SQL 进行的写入操作将不会受到主键唯一性约束的限制，这可能导致数据中出现主键重复的情况。因此，在选择此模式时，您需要对数据的写入来源和写入方式进行审慎的考虑和管理，以避免潜在的数据质量问题。

-# TIMESTAMP
-
-`TIMESTAMP` 类型用于表示日期和时间戳，可以包含时区信息。默认情况下，时间戳表示为本地时间（TIMESTAMP_LTZ）。所有操作都在当前会话的时区中执行，输出结果也以当前 Lakehouse 所在服务的时区为准。支持用户输入多种格式的时间戳，并自动转换为`TIMESTAMP`类型。输出结果为字符串格式，格式为 `'yyyy-MM-dd HH:mm:ss'`。如果用户输入包含毫秒，则输出结果也会包含毫秒。最大精度支持到微秒（µs），实际精度取决于写入时的时间戳精度。
-
-## 语法
-```
-TIMESTAMP | TIMESTAMP_LTZ
-```
-
-## 示例
-1. 使用默认时间戳格式：
-```
-SELECT TIMESTAMP '2022-12-31 00:00:00';
-SELECT TIMESTAMP_LTZ '2022-12-31 00:00:00';
-```
-2. 使用不同格式的时间戳：
-```
-SELECT TIMESTAMP '2022-12-31 00:00:00.123'; -- 包含毫秒
-+------------------------------------+
-
-| TIMESTAMP'2022-12-31 00:00:00.123' |
-
-+------------------------------------+
-
-| 2022-12-31 00:00:00.123            |

-3. 将字符串转换为时间戳类型：
-```
-SELECT CAST('2022-12-31 00:00:00' AS TIMESTAMP);
-SELECT CAST('2022-12-31 00:00:00' AS TIMESTAMP_LTZ);
-```
-4. 使用不同的精度选项：
-```
-SELECT TIMESTAMP  '2022-12-31 00:00:00.123456'; -- 微秒精度
-SELECT TIMESTAMP  '2022-12-31 00:00:00.123'; -- 毫秒精度
-SELECT TIMESTAMP  '2022-12-31 00:00:00'; -- 秒精度

-- 在进行时间戳转换时，请注意时区差异可能导致的误差。
-- 请确保输入的时间戳格式与系统支持的格式相匹配，以免出现错误。

-Time Travel保留期限决定了您可以访问多久以前的数据。例如，如果Time Travel保留期限设置为7天，那么您可以访问过去7天内的任何时间点的数据。超过7天后，您将无法使用Time Travel访问过期的数据，且数据会被物理删除。
-Lakehouse表的历史状态默认保留周期1天（24小时），您可以通过Time Travel查询1天内的历史版本。
-
-如需保留更长周期的历史版本，您可以为每个表设置不同的数据保留周期，以满足不同的业务需求。num的设置范围为0-90。
-
-  * ```SQL
-    ALTER TABLE tablename SET PROPERTIES ('data_retention_days'='num');
-    ```
-## TIMETRAVEL查询语法
-
-```sql
-SELECT 
-    table_identifier TIMESTAMP AS OF timestamp_expression
-```
-
-通过使用TIMESTAMP AS OF子句，用户可以指定具体的时间点，查询保留期内表历史记录中指定点的精确位置或紧邻指定点之前的数据。Timestamp\_expression是一个返回时间戳类型表达式的参数，例如：
-
-* `'2023-11-07 14:49:18'`，即可强制转换为时间戳的字符串。
-* `CAST('2023-11-07 14:49:18' AS TIMESTAMP)`。
-* `CURRENT_TIMESTAMP() - INTERVAL 12 HOURS`。12小时之前的版本
-* 任何本身是时间戳类型或可强制转换为时间戳的表达式。
-
-## 查询说明
-
-* 通过指定时间点，用户可以查询到指定时间的版本数据。
-* 查询的时间点不能早于表创建时间，也不能超出数据保留周期。如果指定的时间点超出范围，将报错。
-* 如果timestamp\_expression是未来时间，也会报错，因为未来的数据是不可用的。
-
-## 权限要求
-
-* 用户需要拥有对表的SELECT权限。
-
-## 使用限制
-
-* View不支持Time Travel查询。
-* 不支持外部schema。
-* RealtimeStream实时写入未提交的数据不支持Time Travel查询，因为RealtimeStream为了提供实时查询功能，会优先写入到临时区，方便快速查询。而Time Travel查询历史版本是依靠查询提交记录，因此暂时无法查询RealtimeStream实时写入未提交的数据。

-# TINYINT
-
-`TINYINT` 是一种 8 位有符号整型数据类型，用于存储范围在 -128 到 127 之间的整数值。它可以有效地节省存储空间，因为它仅使用一个字节来表示数值。
-
-## 语法
-
-```
-TINYINT
-```
-
-
-## 示例
-
-1. 创建一个包含 `TINYINT` 类型列的表：
-
-   ```sql
-   CREATE TABLE example_table (
-       id TINYINT
-   );
-   ```
-
-2. 向 `TINYINT` 类型的列插入数据：
-
-   ```sql
-   INSERT INTO example_table (id) VALUES (-100);
-   INSERT INTO example_table (id) VALUES (100);
-   ```
-
-3. 查询 `TINYINT` 类型列的数据：
-
-   ```sql
-   SELECT id FROM example_table;
-   ```
-
-4. 使用 `TINYINT` 类型列进行条件查询：
-
-   ```sql
-   SELECT id FROM example_table WHERE id > -50;
-   ```
-
-5. 创建一个包含 `TINYINT` 类型列（指定最大显示宽度）的表：
-
-   ```sql
-   CREATE TABLE example_table2 (
-       age TINYINT
-   );
-   ```
-
-6. 向 `TINYINT` 类型列（指定最大显示宽度）插入数据：
-
-   ```sql
-   INSERT INTO example_table2 (age) VALUES (25y);
-   ```
-7.  `TINYINT`  常量格式：
-
-   ```sql
-    SELECT 11y
-   ```
-## 注意事项
-
-- `TINYINT` 类型仅适用于存储较小的整数值。对于较大的数值，建议使用 `INT` 或 `BIGINT` 类型。
-- 当使用 `TINYINT` 类型存储负数时，数值范围为 -128 到 -1。若尝试插入超出此范围的负数，将导致溢出错误。
-- 当使用 `TINYINT` 类型存储正数时，数值范围为 1 到 127。若尝试插入超出此范围的正数，将导致溢出错误。

-# 三分钟用一瓶水的代价体验TPC-H 100G性能测试
-
-TPC-H 是由事务处理性能委员会 (TPC) 开发的决策支持基准。它由一套面向业务的临时查询和并发数据修改组成。TPC-H 可以根据真实的生产环境建立模型，模拟销售系统的数据仓库。本次测试使用 8 张表，数据大小为 100 GB。总共测试了 22 个查询，主要性能指标是每个查询的响应时间，即从提交查询到返回结果之间的持续时间。
-TPC-H 性能测试是一个费时、费钱的过程。为了完成测试，需要准备机器、准备数据、生成报告等，往往需要数天时间以及高昂的费用。基于云器 Lakehouse 秒级弹性伸缩的虚拟集群以及共享的 TPC-H 数据集，免去了资源和数据的准备过程。基于本文提供的方法，您可以在 3 分钟内体验云器 Lakehouse 的完整性能测试并查看对比报告。
-本文代码运行在[Zeppelin](eco_integration/Zeppelin.md)。如果您想运行本文代码，请按照文档说明安装[Zeppelin](eco_integration/Zeppelin.md)。
-
-## 创建测试用AP VC
-
-```
--- 创建分析型虚拟计算资源
-create vcluster if not exists VC_TPCH_100GB vcluster_size='Large' vcluster_type='Analytics'  AUTO_RESUME=TRUE AUTO_SUSPEND_IN_SECOND=300 min_replicas=1 max_replicas=1 comment 'TPCH 100GB TEST';
-
-use vcluster VC_TPCH_100GB;
-```
-
-## 了解待测试数据
-
-本测试使用TPC-H 100 GB dataset。基于云器Lakehouse天生的存算分离架构，共享了该数据集（clickzetta\_sample\_data.tpch\_100g），用户可以直接访问，从而免去了数据准备过程。
-
-```
-select "customer" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.customer
-union all select "lineitem" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.lineitem
-union all select "nation" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.nation
-union all select "orders" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.orders
-union all select "part" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.part
-union all select "partsupp" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.partsupp
-union all select "region" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.region
-union all select "supplier" as tablename, count(*) as row_count from clickzetta_sample_data.tpch_100g.supplier;
-```
-
-运行上述代码，得到测试数据集每张表的行数：

-
-## 测试过程
-
-![](.topwrite/assets/20240618195336_rec_.gif)
-
-整个过程耗时不到 3 分钟，其中 22 个 SQL 查询运行总计耗时 16.718 秒。费用方面，本次测试采用的是 Large 规格的虚拟计算集群，3 分钟的费用约为 1.38 元，相当于用一瓶水的代价完成了本次测试。

-# TRUNCATE TABLE
-
-## 功能
-
-`TRUNCATE TABLE` 命令用于快速删除表中的所有记录，但表结构及其属性将保持不变。与 `DROP TABLE` 命令不同，`TRUNCATE TABLE` 不会完全删除表，而仅删除表中的数据。
-
-## 语法
-
-```SQL
-TRUNCATE TABLE  [ IF EXISTS ] table_name;
-```
-
-**必选参数**
-
-* `table_name`：指定要清空数据的表名。
-
-**可选参数**
-
-* `IF EXISTS`：如果指定的表不存在，则不报错并继续执行其他操作。
-
-## 使用示例
-
-1. 清空名为 `employees` 的表中的所有记录：
-   ```SQL
-   TRUNCATE TABLE employees;
-   ```
-
-2. 清空表 `employees`，如果表不存在，则不报错：
-   ```SQL
-   TRUNCATE TABLE IF EXISTS employees;
-   ```
-
-# TRUNCATE TABLE PARTITION
-
-## 功能
-
-`TRUNCATE TABLE PARTITION` 命令用于清空分区表中指定分区的数据。支持通过条件筛选方式清空分区数据。如果您希望一次性清空符合某个规则条件的一个或多个分区，可以使用表达式指定筛选条件，通过筛选条件匹配分区并批量清空分区数据。
-
-## 语法
-
-* 指定分区删除：
-
-```SQL
-TRUNCATE TABLE <table_name> PARTITION (<pt_spec>)[, PARTITION (<pt_spec>)....];
-```
-
-* 指定分区筛选条件：
-
-```SQL
-TRUNCATE TABLE <table_name>  <partition_expression>;
-partition_expression::=
-   PARTITION (<partition_col> <relational_operators> <partition_col_value>)
-   | PARTITION (scalar(<partition_col>) <relational_operators> <partition_col_value>)
-   | PARTITION (<partition_filter> AND|OR <partition_filter>)
-   | PARTITION (NOT <partition_filter>)
-   | PARTITION (<partition_filter>)[,PARTITION (<partition_filter>), ...]
-```
-
-**参数说明**
-
-* `table_name`：指定表的名字。
-* `IF EXISTS`：如果表不存在，加上此参数执行该命令则不会报错。
-* `pt_spec`：必填。待清空数据的分区。当有多个分区字段格式为`(partition_col1 = partition_col_value1, partition_col2 = partition_col_value2, ...)`。partition\_col是分区字段，partition\_col\_value是分区值。分区字段不区分大小写，分区值区分大小写。支持指定多个分区值，使用逗号分隔。
-* `partition_expression`：可以包含以下几种形式：
-
-  1. **基于分区列的比较操作**：
-
-  ```SQL
-  PARTITION (<partition_col> <relational_operators> <partition_col_value>)
-  ```
-
-  * `<partition_col>`：分区表中的分区列名。
-  * `<relational_operators>`：关系运算符，如 `=`、<`、`>、<=`、`>、`<>`。
-  * `<partition_col_value>`：与分区列进行比较的值。
-  * 示例如下：
-
-  ```SQL
-  PARTITION (scalar(<partition_col>) <relational_operators> <partition_col_value>)
-  ```
-
-  * `scalar` 函数是返回单个值的函数，用于将分区列的值转换为标量值。目前lakehouse支持的分区scalar函数包含时间函数、json函数、数学函数、加密函数、正则函数、字符串函数。
-
-  * 示例如下：
-
-    ```
-    TRUNCATE TABLE sales PARTITION (lower(pt)=product1);
-    ```
-
-  2. **基于分区过滤器的复合条件**：
-
-  ```SQL
-  PARTITION (<partition_filter> AND|OR <partition_filter>)
-  ```
-
-  * `<partition_filter>`：可以是任何有效的分区过滤条件。
-  * `AND|OR`：逻辑运算符，用于组合多个过滤条件。
-  * 示例如下：
-
-    ```
-    TRUNCATE TABLE sales  PARTITION(pt1='2023' and pt2='03');
-    ```
-
-  3. **基于分区过滤器的否定条件**：
-
-  ```SQL
-  PARTITION (NOT <partition_filter>)
-  ```
-
-  * `NOT`：逻辑非运算符，用于否定一个过滤条件。
-  * 示例如下：
-
-    ```
-    TRUNCATE TABLE sales  PARTITION(pt2 not in('01','04'));
-    ```
-
-  4. **多个分区过滤器的列表**：
-
-  ```SQL
-  PARTITION (<partition_filter>)[,PARTITION (<partition_filter>), ...]
-  ```
-
-  * 允许您列出多个分区过滤条件，每个条件之间用逗号分隔。
-
-## 使用示例
-
-1. 指定分区清空
-   ```sql
-   --从表sale_detail中清空一个分区
-   TRUNCATE  TABLE sale_detail PARTITION (pt = '202402', region = 'beijing');
-   --从表sale_detail中同时清空两个分区，清空2024年1月杭州和上海地域的销售记录。
-   TRUNCATE  TABLE sale_detail PARTITION (pt = '201401', region = 'hangzhou'),
-   PARTITION (pt = '201401', region = 'shanghai');
-   ```
-
-2. 使用过滤条件清空 `sales` 表中满足分区条件 `year < 2024 AND quarter = 1` 的所有分区：
-   ```SQL
-   TRUNCATE  TABLE sales PARTITION 
-   (
-   YEAR < 2024 AND      
-   QUARTER = 1
-   );
-   ```

-# UNDROP TABLE 语句
-
-使用 UNDROP TABLE 语句可以恢复被删除的表、动态表和物化视图。是否可以恢复被删除的对象取决于数据的[保留周期](TIMETRAVEL.md)。
-
-**数据保留周期**
-
-对象能否被恢复取决于数据的保留周期。当前预览版本的数据保留周期默认为 7 天，未来将调整为 1 天。您可以通过执行 [ALTER 命令](alter.md) 来调整保留周期。请注意，修改保留周期可能会增加存储成本。
-
-**支持的对象类型**：
-
-* 表（TABLE）
-* 动态表（DYNAMIC TABLE）
-* 物化视图（MATERIALIZED VIEW）
-
-## 语法
-
-```sql
-UNDROP TABLE tablename;
-```
-
-## 参数说明
-
-* **tablename**：指定被删除的表的名称。支持恢复动态表、内部表、物化视图。
-
-## 示例
-
-### 示例 1：删除表后立即恢复
-
-```sql
--- 创建表
-CREATE TABLE mytable(id int, name string);
-INSERT INTO mytable VALUES(1, 'aaa');

-# 更新表记录
-
-## 功能描述
-更新数据库表中的记录，将指定的字段值修改为新的值。
-
-## 语法格式
-```SQL
-UPDATE target_table
-       SET column_name1 = new_value1 [ , column_name2 = new_value2 , ... ]
-  [ WHERE condition ]
-[ORDER BY ...] 
-[LIMIT row_count]
-```
-
-**必选参数**
-
-- `target_table`：需要更新记录的目标表名。
-- `column_name`：需要更新的列名。
-- `new_value`：新的值，可以是常量、变量、函数调用、算术运算符、字符串操作等。支持子查询。
-
-**可选参数**
-- `condition`：更新操作的条件，用于限定哪些记录需要被更新。条件可以包含子查询和表达式。
-- `ORDER BY ...`‌按指定列排序后更新：
-  * 通常与 `LIMIT` 配合使用，控制更新顺序。
-  * 适用于分批更新或按优先级处理数据（如先处理最新记录）。
-- `LIMIT row_count`：限制更新的最大行数：
-  * 常用于分批更新大数据表，避免锁表或事务过长。
-  * 需配合 `ORDER BY` 确保更新顺序的确定性。
-
-
-## 使用示例
-
-### 示例1：更新单个字段值
-假设我们有一个名为`employees`的表，包含员工的ID、姓名和工资。现在我们要将ID为1的员工的工资增加1000元。
-
-```SQL
-UPDATE employees
-SET salary = salary + 1000
-WHERE id = 1;
-```
-
-### 示例2：同时更新多个字段值
-继续使用`employees`表，现在我们要将ID为1的员工的工资增加1000元，并将职位从"Developer"更改为"Senior Developer"。
-
-```SQL
-UPDATE employees
-SET salary = salary + 1000, position = 'Senior Developer'
-WHERE id = 1;
-```
-
-### 示例3：使用子查询更新字段值
-假设我们有一个名为`orders`的表，包含订单ID、客户ID和订单金额。我们还有一个名为`customers`的表，包含客户ID、姓名和会员等级。现在我们要将所有VIP客户的订单金额增加10%。
-
-```SQL
-UPDATE orders
-SET amount = amount * 1.1
-WHERE customer_id IN (
-  SELECT id
-  FROM customers
-  WHERE membership_level = 'VIP'
-);
-```
-### 示例4：UPDATE语句带有ORDER BY
-```
-UPDATE t SET id = id + 1 ORDER BY id DESC;
-```
-
-## 注意事项
-- 在执行更新操作时，请确保`WHERE`子句正确无误，以免错误地更新了不应该更新的记录。
-- 在对生产环境进行更新操作之前，建议先在测试环境中进行验证。

-### 功能描述
-
-`USE SCHEMA` 语句旨在改变当前会话的默认 SCHEMA 设置。当您执行此操作后，所有未明确指定 SCHEMA 的 SQL 查询和命令都将在新设定的 SCHEMA 范围内执行。这有助于简化 SQL 语句的编写，提高工作效率。
-
-### 语法
-
-```SQL
-USE [SCHEMA] schema_name;
-```
-
-### 参数说明
-
-- `schema_name`: 您希望切换至的目标 SCHEMA 名称。
-
-### 使用示例
-
-1. 切换至名为 `reporting` 的 SCHEMA：
-
-   ```SQL
-   USE reporting;
-   ```
-
-2. 在执行一系列针对 `sales` 数据表的操作时，首先切换至相应的 SCHEMA：
-
-   ```SQL
-   USE sales_schema;
-   SELECT * FROM sales_data;
-   UPDATE sales_data SET quantity = 100 WHERE product_id = 12;
-   ```
-
-3. 当需要在不同的 SCHEMA 之间频繁切换时，可以通过 `USE` 语句快速定位至特定的数据集合：
-
-   ```SQL
-   -- 从当前的 sales_schema 切换至 customer_schema
-   USE customer_schema;
-   -- 查询客户信息
-   SELECT * FROM customers;
-   -- 切换回 sales_schema
-   USE sales_schema;
-   ```
-
-4. 如果您希望在创建表时指定 SCHEMA，但不想立即切换至该 SCHEMA，可以在创建表的语句中包含 SCHEMA 名称，而无需使用 `USE` 语句：
-
-   ```SQL
-   CREATE TABLE finance_schema.ledger (
-     id INT PRIMARY KEY,
-     amount DECIMAL(10, 2) NOT NULL
-   );
-   ```

-## 注意事项
-- 在使用客户端工具（如[客户端SQLLine](<connect-with-cli.md>)、[DBeaver](<eco_integration/dbeaver-lakehouse.md>)等）连接时，相关操作会在整个会话期间生效。而如果您使用 Lakehouse Studio 界面，建议优先通过页面来切换 Schema 和计算集群。需要说明的是，若直接使用相关命令，其效果仅临时生效，且要和需要执行的SQL一起选中执行方可生效。

-     ↓              ↓              ↓            ↓            ↓
-  原始图像         增量检测       AI UDF调用     数据解析入库   可视化报表
-```
-
-### 工作流实现
-
-![](.topwrite/assets/AIworkflow.png =743)
-
-#### **Task 1: 数据源刷新与增量检测**
-
-```sql
--- 刷新 Volume，检测新增图像文件

-
--- 记录刷新时间点，用于后续增量处理
-SET refresh_timestamp = CURRENT_TIMESTAMP();
-```
-
-**最佳实践要点**：
-
-* 定期刷新 Volume 以发现新文件
-* 使用时间戳记录刷新点，支持增量处理
-* 建议根据业务需求设置合理的刷新频率（如每 5 分钟）
-
-#### **Task 2: AI 识别与结构化处理**
-
-```sql
--- 增量处理最近 ${last_min} 分钟内的新图像
-WITH check_new_files AS (
-    SELECT COUNT(*) AS file_count
-    FROM DIRECTORY(VOLUME sg_volume_images)
-    WHERE last_modified_time >= DATEADD(MINUTE, -${last_min}, CURRENT_TIMESTAMP())
-),
--- AI 识别处理
-recognition AS (
-    SELECT *
-    FROM (
-        SELECT 
-            relative_path as vehicle_images,
-            pre_signed_url,
-            -- 调用 AI 外部函数进行车辆识别
-            public.fc_image_to_text('vehicle_type', pre_signed_url) as vehicle_recognition,
-            last_modified_time
-        FROM (
-            SELECT 
-                relative_path,
-                -- 生成临时访问 URL，有效期 2 小时
-                get_presigned_url(volume sg_volume_images, relative_path, 7200) as pre_signed_url,
-                last_modified_time
-            FROM DIRECTORY(VOLUME sg_volume_images)
-            WHERE last_modified_time >= DATEADD(MINUTE, -${last_min}, CURRENT_TIMESTAMP())
-        )
-    ) subq
-    WHERE EXISTS (SELECT 1 FROM check_new_files WHERE file_count > 0)
-)
--- 解析 AI 返回的 JSON 结果并入库
-INSERT INTO vehicle_type_data (
-    car_model, car_color, year, score, 
-    vehicle_recognition, pre_signed_url, last_modified_time, process_time
-)
-SELECT 
-    get_json_object(regexp_replace(vehicle_recognition, "'", '"'), '$.result[0].name') as car_model,
-    get_json_object(regexp_replace(vehicle_recognition, "'", '"'), '$.color_result') as car_color,
-    get_json_object(regexp_replace(vehicle_recognition, "'", '"'), '$.result[0].year') as year,
-    cast(get_json_object(regexp_replace(vehicle_recognition, "'", '"'), '$.result[0].score') as decimal(16,6)) as score,
-    vehicle_recognition,
-    r.pre_signed_url,
-    last_modified_time,
-    CURRENT_TIMESTAMP() as process_time
-FROM recognition r
-WHERE EXISTS (SELECT 1 FROM check_new_files WHERE file_count > 0);
-```
-
-**最佳实践要点**：
-
-* 使用 CTE 进行增量检测，避免处理已识别的图像
-* 生成预签名 URL 供 AI 服务访问，确保安全性
-* JSON 解析时注意引号转换和数据类型转换
-* 记录处理时间，便于监控和审计
-
-#### **Task 3: 数据质量控制与异常处理**
-
-```sql
--- 数据质量检查和异常处理
-WITH quality_check AS (
-    -- 检查识别失败的记录
-    SELECT 
-        vehicle_images,
-        pre_signed_url,
-        vehicle_recognition,
-        CASE 
-            WHEN vehicle_recognition IS NULL THEN 'AI服务调用失败'
-            WHEN score < 0.6 THEN '识别置信度过低'
-            WHEN car_model IS NULL THEN '车型识别失败'
-            ELSE '正常'
-        END as quality_status
-    FROM vehicle_type_data
-    WHERE process_time >= DATEADD(MINUTE, -${last_min}, CURRENT_TIMESTAMP())
-)
--- 将异常记录写入错误日志表
-INSERT INTO vehicle_recognition_errors (
-    vehicle_images, pre_signed_url, error_type, 
-    error_details, retry_count, created_time
-)
-SELECT 
-    vehicle_images,
-    pre_signed_url,
-    quality_status as error_type,
-    vehicle_recognition as error_details,
-    0 as retry_count,
-    CURRENT_TIMESTAMP() as created_time
-FROM quality_check
-WHERE quality_status != '正常';
-
--- 更新处理统计信息
-MERGE INTO vehicle_process_stats AS target
-USING (
-    SELECT 
-        DATE(CURRENT_TIMESTAMP()) as process_date,
-        COUNT(*) as total_processed,
-        SUM(CASE WHEN quality_status = '正常' THEN 1 ELSE 0 END) as success_count,

-  ![](.topwrite/assets/image_1742439851780.png)
-
-### 关键组件：
-
-* **AWS S3**：存储非结构化数据。
-* **非结构化数据**：从S3摄取非结构化数据，将其转换为JSON格式。
-* **非结构化Lakehouse连接器**：将数据加载到Lakehouse。
-* **Lakehouse**：存储和管理用于RAG应用的转换数据，带有向量索引和倒排索引。
-
-在本快速教程中，我们将从S3存储桶中摄取PDF/邮件/图像，使用Unstructured将其转换为标准化的JSON，然后进行分块、嵌入并加载到Lakehouse表中。之后，RAG应用可以从Lakehouse中检索数据，并以适用于RAG应用的格式获取嵌入数据和文本/图像内容。
-
-### 先决条件：
-
-A. 获取您的[Unstructured Serverless API密钥](https://www.google.com/url?q=https%3A%2F%2Funstructured.io%2Fapi-key-hosted)。它提供14天试用，每天最多1000页。
-
-B. 获取您的[Lakehouse账户](https://www.yunqi.tech/)。它提供1个月试用和200元优惠券。
-
-C. 创建一个AWS S3存储桶，并填充您选择的PDF文件。请务必记录下您的凭证。
-
-D. 安装必要的库：
-
-1. 打开终端并创建新的Python 3.9.21环境，命名为“非结构化”：
-
-```
-conda create -n unstructured python=3.9
-conda activate unstructured
-```
-
-然后选择非结构化作为当前环境
-
-2. 您可以联系<qiliang@clickzetta.com>获取unstructured\_ingest-0.5.5-py3-none-any.whl。
-
-您可以[从GitHub存储库获取源代码](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/Zettapark/Unstructured_data_ETL_from_S3_to_Singdata_Lakehouse.ipynb)。
-
-```
-!pip install -U dist/unstructured_ingest-0.5.5-py3-none-any.whl --force-reinstall
-!pip install -U "unstructured-ingest[s3, pdf, clickzetta, embed-huggingface]"
-!pip install --force-reinstall "unstructured-ingest[clickzetta]"
-!pip install python-dotenv
-```
-
-```python
-import json
-import pandas as pd
-import logging
-import warnings
-
-logging.basicConfig(level=logging.ERROR)
-warnings.filterwarnings("ignore", category=UserWarning)
-
-# 如果您想删除表，请将drop_tables设置为True
-drop_tables = True
-```
-
-### 加载环境变量
-
-在此示例中，我们从Localfile的.env文件中加载所有包含机密信息的环境变量。.env文件包含以下变量：
-
-cz\_username：连接到Lakehouse服务的用户名
-
-cz\_password：连接到Lakehouse服务的密码
-
-cz\_service：要连接的Lakehouse服务名称
-
-cz\_instance：要连接的Lakehouse服务实例名称
-
-cz\_workspace：要连接的Lakehouse服务工作区名称
-
-cz\_schema：要连接的Lakehouse服务架构名称
-
-cz\_vcluster：要连接的Lakehouse服务虚拟集群名称
-
-AWS\_KEY：连接到AWS服务的密钥
-
-AWS\_SECRET：连接到AWS服务的密钥
-
-AWS\_S3\_NAME：连接到AWS S3服务的存储桶名称
-
-UNSTRUCTURED\_API\_KEY：连接到UNSTRUCTURED API的API密钥
-
-UNSTRUCTURED\_URL：连接到UNSTRUCTURED API的URL
-
-```python
-import os
-import dotenv
-
-dotenv.load_dotenv('./.env') # 替换为您.env文件的路径
-```
-
-```
-True
-```
-
-### 将非结构化数据放入AWS S3
-
-![](.topwrite/assets/image_1742439828203.png)
-
-### 在Lakehouse中创建索引
-
-在构建非结构化数据预处理管道之前，让我们先在Lakehouse中创建一个架构和一个表，用于存储处理后的数据。
-
-有关架构的示例，请参阅[非结构化文档](https://docs.unstructured.io/api-reference/ingest/destination-connector/singlestore#singlestore-table-schema)。如果您将使用文档中的架构，请确保嵌入式的`dims`值与您选择使用的嵌入模型的维度数量相匹配。在此示例中，它设置为768，但您的嵌入模型可能会产生不同维度的向量。
-
-```python
-# 定义用于在Lakehouse中存储数据的表名。
-raw_table_name = "raw_elements"
-silver_table_name = "elements"
-embeddings_dimensions = 768
-```
-
-```python
-# 获取连接到Lakehouse的连接参数。
-_username = os.getenv("cz_username")
-_password = os.getenv("cz_password")
-_service = os.getenv("cz_service")
-_instance = os.getenv("cz_instance")
-_workspace = os.getenv("cz_workspace")
-_schema = os.getenv("cz_schema")
-_vcluster = os.getenv("cz_vcluster")
-```
-
-Silver表旨在存储与文件和元素相关的各种元数据和内容。这两个索引优化了特定查询的性能：
-
-倒排文本索引增强了全文检索功能，使得基于文本内容查找记录更加容易。
-
-向量索引优化了向量数据的相似性搜索，这对于基于嵌入式数据比较和查找相似元素的任务非常有用。
-
-对于RAG（检索增强生成）应用开发的好处：
-
-增强搜索效率：通过支持倒排和向量搜索，此表允许RAG应用基于文本内容和语义相似性高效检索相关信息。这增强了模型查找和生成上下文相关响应的能力。
-
-提高准确性：全文和相似性搜索的结合确保了RAG应用可以访问更广泛的相关数据，从而提高了生成内容的准确性和相关性。
-
-可扩展性：借助优化的索引，该表可以处理大量数据并快速执行搜索，支持RAG应用的可扩展性需求。
-
-简化架构：将倒排文本和向量搜索功能结合到一个表中，消除了对单独的文本和向量搜索数据库的需求。这简化了维护，减少了运营开销，并提高了开发效率。
-
-数据一致性：将数据副本数量从三个减少到一个，提高了数据一致性，最小化了数据重复，并减少了数据同步和移动的需求。
-
-总体而言，这些索引确保了对文本和嵌入式字段的搜索和检索高效进行，支持快速准确的查询结果，这对于开发有效且高效的RAG应用至关重要。

-# VARCHAR(n)
-
-变长字符类型（VARCHAR）是一种可存储可变长度的字符串数据类型。该类型在存储字符串时会根据实际内容的长度进行分配空间，从而有效节省存储空间。VARCHAR 类型的字符串长度范围为 1 到 65535 个字符。
-
-## 语法
-
-```
-VARCHAR(n)
-```
-
-其中，n 表示字符串的最大长度，取值范围为 1 到 1048576。
-
-## 示例
-
-1. 创建一个 VARCHAR 类型的表：
-
-   ```
-   CREATE TABLE example_table (
-       id INT PRIMARY KEY,
-       name VARCHAR(50),
-       age INT
-   );
-   ```
-
-   在这个例子中，我们创建了一个名为 example_table 的表，其中包含三个字段：id（整数类型，主键）、name（变长字符类型，最大长度为 50 个字符）和 age（整数类型）。
-
-2. 向 VARCHAR 类型的字段插入数据：
-
-   ```
-   INSERT INTO example_table (id, name, age) VALUES (1, '张三', 25);
-   ```
-
-   在这个例子中，我们向 example_table 表中插入了一条数据，其中 name 字段的值为 '张三'，长度为 3 个字符。
-
-3. 查询 VARCHAR 类型字段的数据：
-
-   ```
-   SELECT name FROM example_table;
-   ```
-
-   在这个例子中，我们查询了 example_table 表中 name 字段的数据。

-# VIEW（视图）
-视图是一种虚拟表，它是由 SQL 查询定义的。通过创建视图，您可以像查询普通表一样查询视图。当用户查询视图时，查询结果将仅包含在定义视图的查询中指定的表和字段的数据。
-
-## 视图的优势
-
-1. 简化复杂的 SQL 查询：通过将复杂的查询定义为视图，您可以在需要时直接查询视图，而无需每次都重写复杂的查询。
-2. 保护数据：视图可以限制用户访问基础表中的数据，只允许他们访问视图中定义的数据。
-3. 更好的数据组织：视图可以帮助您更好地组织和管理数据，使其更易于理解和使用。
-
-## 视图的限制
-
-1. 视图是只读的，无法对视图执行 DML（插入、更新、删除）操作。
-2. 视图的性能可能会受到基础表数据量和查询复杂度的影响。
-
-## 视图管理
-
-- [创建视图](CREATEVIEW.md)：通过指定 SQL 查询来创建视图。
-- [删除视图](DROPVIEW.md)：删除已存在的视图。
-- [查看视图详情](DESCVIEW.md)：查看视图的结构和定义。
-
-## 使用案例
-
-1. 计算利润和税后收入：
-
-   ```
-   CREATE VIEW v_sales AS
-   SELECT revenue - cost AS profit, (revenue - cost) * tax_rate AS tax_amount, (revenue - cost) * (1 - tax_rate) AS net_income
-   FROM table1;
-   ```
-
-2. 筛选特定部门的员工信息：
-
-   ```
-   CREATE VIEW v_sales_department AS
-   SELECT id, name, position, salary
-   FROM employees
-   WHERE department = 'Sales';
-   ```
-
-3. 汇总每个月的销售数据：
-
-   ```
-   CREATE VIEW v_monthly_sales AS
-   SELECT DATE_TRUNC('month', sale_date) AS month, SUM(revenue) AS total_sales
-   FROM sales_data
-   GROUP BY month;

-# LIST 命令
-
-## 简介
-
-LIST 命令返回已经存储在 Lakehouse 内部或者外部 Volume 中的文件列表。该命令可以在 Studio 和 Lakehouse 客户端中运行。
-
-## 使用场景
-
-* **导入前文件验证**：在将数据文件导入表前，确认文件已成功上传到 Volume 中，并检查文件命名是否符合规范。
-* **导出后确认**：使用 COPY INTO 将数据导出到 Volume 后，验证所有文件是否正确生成，以及文件大小是否合理。
-* **文件清理前确认**：在执行 REMOVE 命令删除 Volume 中的文件前，可使用 LIST 命令确认文件列表，避免误操作。
-
-## 语法
-
-```
-LIST { VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME } 
-     [ SUBDIRECTORY 'subdir'| REGEXP = 'pattern' ]
-```
-
-## 参数说明
-
-* `VOLUME volume_name `：列出指定外部 VOLUME 中的所有文件。
-* `TABLE VOLUME table_name `：列出指定表的 VOLUME 空间下的所有文件。
-* `USER VOLUME `：列出当前用户的 Volume 空间下的所有文件。
-* `SUBDIRECTORY 'subdir': `：可选参数。用于指定要列出内容的 Volume 子目录，此选项可帮助缩小结果范围。
-* `REGEXP = 'pattern': `：可选参数。用于指定过滤返回文件的正则表达式模式，您可以精确筛选出符合特定命名规则或格式的文件。
-
-## 示例
-
-* 列出外部 VOLUME `foodimages` 中所有含有数字“1”的文件：
-
-```
-LIST VOLUME foodimages REGEXP = '.*1.*'
-```
-
-* 列出外部 VOLUME `parquet_files` 中，`t_search_log` 子目录中的所有文件：
-
-```
-LIST VOLUME parquet_files SUBDIRECTORY 't_search_log'
-```
-
-* 列出外部 VOLUME `parquet_file` 中，`t_search_log` 子目录中以 `c000` 结尾的文件：
-
-```
-LIST VOLUME parquet_file SUBDIRECTORY 't_search_log' REGEXP = '.*c000' ;
-```
-
-## 注意事项
-
-* 用户必须具有相应 Volume 的 `READ ` 权限才能执行 `LIST ` 命令。

-# 窗口函数（Window Function）
-
-## 概述
-
-窗口函数（Window Function）是云器Lakehouse SQL中一种强大的分析功能，它允许在一组相关行上执行计算，而不仅仅是针对单个行。通过使用WINDOW子句，可以定义一个或多个命名的窗口，然后在窗口函数中引用这些窗口，避免重复编写相同的窗口规范，使查询更加简洁和易维护。
-
-## 语法
-
-```sql
-WINDOW <window_name> AS (<window_specification>, ...)
-```
-
-### 参数说明
-
-* **window\_name**: 窗口的名称，必须是有效的标识符，不能与表名或列名冲突
-* **window\_specification**: 窗口规范，定义窗口的范围和顺序，包含以下部分：
-  * `PARTITION BY`: 指定数据分组方式，每个组是一个分区
-  * `ORDER BY`: 指定每个分区内的数据排序方式
-  * `frame_clause`: 指定窗口框架，限制窗口函数的计算范围
-
-### 窗口框架类型
-
-1. **ROWS Frame**: 基于行数的窗口框架
-2. **RANGE Frame**: 基于值范围的窗口框架
-
-## 环境准备
-
-### 创建测试表
-
-```sql
-CREATE TABLE IF NOT EXISTS sales(
-    month INT,
-    sales INT,
-    profit DOUBLE
-);
-```
-
-### 插入测试数据
-
-```sql
-INSERT INTO sales (month, sales, profit) VALUES
-(1, 100, 0.1),
-(2, 120, 0.15),
-(3, 80, 0.05),
-(4, 150, 0.2),
-(5, 90, 0.1),
-(6, 110, 0.12);
-```
-
-## 使用示例
-
-### 示例1：移动窗口聚合 - 计算移动和与移动平均
-
-**业务场景**: 计算当前月及前两个月的销售总和与平均值
-
-```sql
-SELECT month, sales, 
-       SUM(sales) OVER w AS sum_sales, 
-       AVG(sales) OVER w AS avg_sales
-FROM sales
-WINDOW w AS (ORDER BY month ROWS BETWEEN 2 PRECEDING AND CURRENT ROW);
-```
-
-**执行结果**:
-
-```
-+-------+-------+-----------+--------------------+
-| month | sales | sum_sales | avg_sales          |
-+-------+-------+-----------+--------------------+
-| 1     | 100   | 100       | 100.0              |
-| 2     | 120   | 220       | 110.0              |
-| 3     | 80    | 300       | 100.0              |
-| 4     | 150   | 350       | 116.67             |
-| 5     | 90    | 320       | 106.67             |
-| 6     | 110   | 350       | 116.67             |
-+-------+-------+-----------+--------------------+
-```
-
-**说明**: 窗口w定义了一个滑动窗口，包含当前行和前2行，因此每行都会计算最近3个月的销售总和与平均值。
-
-***
-
-### 示例2：多窗口排名 - 季度排名与年度排名
-
-**业务场景**: 同时计算销售额在季度内和全年的排名
-
-```sql
-SELECT month, sales, 
-       RANK() OVER w1 AS rank_quarter, 
-       ROW_NUMBER() OVER w2 AS rank_year
-FROM sales
-WINDOW w1 AS (PARTITION BY CEIL(month / 3) ORDER BY sales DESC),
-       w2 AS (ORDER BY sales DESC);
-```
-
-**执行结果**:
-
-```
-+-------+-------+--------------+-----------+
-| month | sales | rank_quarter | rank_year |
-+-------+-------+--------------+-----------+
-| 4     | 150   | 1            | 1         |
-| 2     | 120   | 1            | 2         |
-| 6     | 110   | 2            | 3         |
-| 1     | 100   | 2            | 4         |
-| 5     | 90    | 3            | 5         |
-| 3     | 80    | 3            | 6         |
-+-------+-------+--------------+-----------+
-```
-
-**说明**:
-
-* w1窗口按季度（每3个月）分区，计算各季度内的销售排名
-* w2窗口不分区，计算全年的销售排名
-* 使用CEIL(month/3)将月份分为Q1(1-3月)、Q2(4-6月)等
-
-***
-
-### 示例3：累积聚合 - 从年初至今的统计
-
-**业务场景**: 计算从年初到当前月的累积销售额、平均利润率等
-
-```sql
-SELECT month, sales, profit,
-       SUM(sales) OVER w AS cumulative_sales,
-       AVG(profit) OVER w AS avg_profit,
-       MAX(sales) OVER w AS max_sales,
-       MIN(sales) OVER w AS min_sales
-FROM sales
-WINDOW w AS (ORDER BY month ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW);
-```
-
-**执行结果**:
-
-```
-+-------+-------+--------+------------------+------------+-----------+-----------+
-| month | sales | profit | cumulative_sales | avg_profit | max_sales | min_sales |
-+-------+-------+--------+------------------+------------+-----------+-----------+
-| 1     | 100   | 0.1    | 100              | 0.1        | 100       | 100       |
-| 2     | 120   | 0.15   | 220              | 0.125      | 120       | 100       |
-| 3     | 80    | 0.05   | 300              | 0.1        | 120       | 80        |
-| 4     | 150   | 0.2    | 450              | 0.125      | 150       | 80        |
-| 5     | 90    | 0.1    | 540              | 0.12       | 150       | 80        |
-| 6     | 110   | 0.12   | 650              | 0.12       | 150       | 80        |
-+-------+-------+--------+------------------+------------+-----------+-----------+
-```
-
-**说明**: `UNBOUNDED PRECEDING`表示从分区的第一行开始，`CURRENT ROW`表示到当前行结束，实现累积计算。
-
-***
-
-### 示例4：时间序列分析 - 环比数据对比
-
-**业务场景**: 查看每月销售额与上月、下月的对比及环比变化
-
-```sql
-SELECT month, sales,
-       LAG(sales, 1) OVER w AS prev_sales,
-       LEAD(sales, 1) OVER w AS next_sales,
-       sales - LAG(sales, 1) OVER w AS sales_change
-FROM sales
-WINDOW w AS (ORDER BY month);
-```
-
-**执行结果**:
-
-```
-+-------+-------+------------+------------+--------------+
-| month | sales | prev_sales | next_sales | sales_change |
-+-------+-------+------------+------------+--------------+
-| 1     | 100   | NULL       | 120        | NULL         |
-| 2     | 120   | 100        | 80         | 20           |
-| 3     | 80    | 120        | 150        | -40          |
-| 4     | 150   | 80         | 90         | 70           |
-| 5     | 90    | 150        | 110        | -60          |
-| 6     | 110   | 90         | NULL       | 20           |
-+-------+-------+------------+------------+--------------+
-```
-
-**说明**:
-
-* `LAG(sales, 1)`: 获取上一行的销售额
-* `LEAD(sales, 1)`: 获取下一行的销售额
-* 第一行和最后一行的prev\_sales和next\_sales为NULL
-

-
-### 示例5：多种排名函数对比
-
-**业务场景**: 理解不同排名函数的差异
-
-```sql
-SELECT month, sales,
-       DENSE_RANK() OVER w AS dense_rank,
-       RANK() OVER w AS rank,
-       ROW_NUMBER() OVER w AS row_num,
-       PERCENT_RANK() OVER w AS percent_rank
-FROM sales
-WINDOW w AS (ORDER BY sales DESC);

-| 6     | 110   | 3          | 3    | 3       | 0.4          |
-| 1     | 100   | 4          | 4    | 4       | 0.6          |
-| 5     | 90    | 5          | 5    | 5       | 0.8          |
-| 3     | 80    | 6          | 6    | 6       | 1.0          |
-+-------+-------+------------+------+---------+--------------+
-```
-
-**排名函数说明**:
-
-* `ROW_NUMBER()`: 连续唯一的行号，即使值相同也不会并列
-* `RANK()`: 相同值得到相同排名，下一个排名会跳过
-* `DENSE_RANK()`: 相同值得到相同排名，下一个排名连续
-* `PERCENT_RANK()`: 返回0到1之间的百分比排名
-
-***
-
-### 示例6：位置函数 - 访问特定位置的值
-
-**业务场景**: 获取窗口内第一个、最后一个和指定位置的值
-
-```sql
-SELECT month, sales, profit,
-       FIRST_VALUE(sales) OVER w AS first_sales,
-       LAST_VALUE(sales) OVER w AS last_sales,
-       NTH_VALUE(sales, 2) OVER w AS second_sales
-FROM sales
-WINDOW w AS (ORDER BY month ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING);
-```
-
-**执行结果**:
-
-```
-+-------+-------+--------+-------------+------------+--------------+
-| month | sales | profit | first_sales | last_sales | second_sales |
-+-------+-------+--------+-------------+------------+--------------+
-| 1     | 100   | 0.1    | 100         | 110        | 120          |
-| 2     | 120   | 0.15   | 100         | 110        | 120          |
-| 3     | 80    | 0.05   | 100         | 110        | 120          |
-| 4     | 150   | 0.2    | 100         | 110        | 120          |
-| 5     | 90    | 0.1    | 100         | 110        | 120          |
-| 6     | 110   | 0.12   | 100         | 110        | 120          |
-+-------+-------+--------+-------------+------------+--------------+
-```
-
-**说明**:
-
-* `FIRST_VALUE()`: 返回窗口中第一行的值
-* `LAST_VALUE()`: 返回窗口中最后一行的值（需要UNBOUNDED FOLLOWING才能看到真正的最后一行）
-* `NTH_VALUE(expr, n)`: 返回窗口中第n行的值
-
-***
-
-### 示例7：RANGE窗口框架 - 基于值范围的窗口
-
-**业务场景**: 找出销售额在±10范围内的所有记录并统计
-
-```sql
-SELECT month, sales,
-       SUM(sales) OVER w AS range_sum,
-       COUNT(*) OVER w AS range_count
-FROM sales
-WINDOW w AS (ORDER BY sales RANGE BETWEEN 10 PRECEDING AND 10 FOLLOWING);
-```
-
-**执行结果**:
-
-```
-+-------+-------+-----------+-------------+
-| month | sales | range_sum | range_count |
-+-------+-------+-----------+-------------+
-| 3     | 80    | 170       | 2           |
-| 5     | 90    | 270       | 3           |
-| 1     | 100   | 300       | 3           |
-| 6     | 110   | 330       | 3           |
-| 2     | 120   | 230       | 2           |
-| 4     | 150   | 150       | 1           |
-+-------+-------+-----------+-------------+
-```
-
-**说明**:
-
-* RANGE窗口基于值的范围而非行数
-* 对于sales=100的行，窗口包含销售额在\[90, 110]范围内的所有行
-* 对于sales=150的行，只有它自己在\[140, 160]范围内
-

-
-### 示例8：综合分析 - 多维度业务报表（高级）
-
-**业务场景**: 生成包含排名、累积、环比和占比的综合分析报表
-
-```sql
-SELECT 
-    month,
-    sales,
-    -- 排名相关
-    ROW_NUMBER() OVER w1 AS row_num,
-    RANK() OVER w1 AS sales_rank,
-    -- 累积统计
-    SUM(sales) OVER w2 AS ytd_sales,
-    AVG(sales) OVER w2 AS ytd_avg,
-    -- 环比对比
-    LAG(sales) OVER w1 AS prev_month_sales,
-    sales - LAG(sales) OVER w1 AS mom_change,
-    -- 占比分析

-FROM sales
-WINDOW 
-    w1 AS (ORDER BY month),
-    w2 AS (ORDER BY month ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW),
-    w3 AS (ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING);
-```
-
-**执行结果**:
-
-```
-+-------+-------+---------+------------+-----------+---------+------------------+------------+---------------+
-| month | sales | row_num | sales_rank | ytd_sales | ytd_avg | prev_month_sales | mom_change | pct_of_total  |
-+-------+-------+---------+------------+-----------+---------+------------------+------------+---------------+
-| 1     | 100   | 1       | 1          | 100       | 100.0   | NULL             | NULL       | 15.38         |
-| 2     | 120   | 2       | 2          | 220       | 110.0   | 100              | 20         | 18.46         |
-| 3     | 80    | 3       | 3          | 300       | 100.0   | 120              | -40        | 12.31         |
-| 4     | 150   | 4       | 4          | 450       | 112.5   | 80               | 70         | 23.08         |
-| 5     | 90    | 5       | 5          | 540       | 108.0   | 150              | -60        | 13.85         |
-| 6     | 110   | 6       | 6          | 650       | 108.33  | 90               | 20         | 16.92         |
-+-------+-------+---------+------------+-----------+---------+------------------+------------+---------------+
-```
-
-**说明**:
-
-* 此示例同时使用了3个不同的窗口定义
-* w1: 按月份排序，用于排名和环比
-* w2: 累积窗口，用于YTD（Year-To-Date）计算
-* w3: 完整窗口，用于计算总和并计算占比
-* 展示了如何在一个查询中实现复杂的多维度分析

-### 示例9：数据分桶 - NTILE函数应用
-
-**业务场景**: 将销售数据按业绩分为高中低三档
-
-```sql
-SELECT 
-    month,
-    sales,
-    NTILE(3) OVER w AS sales_tier,
-    CASE 
-        WHEN NTILE(3) OVER w = 1 THEN 'High'
-        WHEN NTILE(3) OVER w = 2 THEN 'Medium'  
-        ELSE 'Low'
-    END AS tier_label
-FROM sales
-WINDOW w AS (ORDER BY sales DESC);
-```
-
-**执行结果**:
-
-```
-+-------+-------+------------+------------+
-| month | sales | sales_tier | tier_label |
-+-------+-------+------------+------------+
-| 4     | 150   | 1          | High       |
-| 2     | 120   | 1          | High       |
-| 6     | 110   | 2          | Medium     |
-| 1     | 100   | 2          | Medium     |
-| 5     | 90    | 3          | Low        |
-| 3     | 80    | 3          | Low        |
-+-------+-------+------------+------------+
-```
-
-**说明**: `NTILE(n)`将排序后的数据尽可能平均地分成n个桶，常用于分层分析、ABC分类等场景。
-
-***
-
-### 示例10：累积分布 - CUME\_DIST函数应用
-
-**业务场景**: 计算每个销售额在整体中的累积分布百分位
-
-```sql
-SELECT 
-    month,
-    sales,
-    CUME_DIST() OVER w AS cumulative_dist,
-    ROUND(CUME_DIST() OVER w * 100, 2) AS percentile
-FROM sales
-WINDOW w AS (ORDER BY sales);
-```
-
-**执行结果**:
-
-```
-+-------+-------+------------------+------------+
-| month | sales | cumulative_dist  | percentile |
-+-------+-------+------------------+------------+
-| 3     | 80    | 0.167            | 16.67      |
-| 5     | 90    | 0.333            | 33.33      |
-| 1     | 100   | 0.500            | 50.00      |
-| 6     | 110   | 0.667            | 66.67      |
-| 2     | 120   | 0.833            | 83.33      |
-| 4     | 150   | 1.000            | 100.00     |
-+-------+-------+------------------+------------+
-```
-
-**说明**: `CUME_DIST()`返回小于或等于当前值的行数占总行数的比例，表示当前值在数据集中的累积分布位置。
-
-***
-
-## 窗口框架详解
-
-### ROWS vs RANGE
-
-| 框架类型  | 说明       | 示例                                            |
-| ----- | -------- | --------------------------------------------- |
-| ROWS  | 基于物理行数   | `ROWS BETWEEN 2 PRECEDING AND CURRENT ROW`    |
-| RANGE | 基于值的逻辑范围 | `RANGE BETWEEN 10 PRECEDING AND 10 FOLLOWING` |
-
-### 边界关键字
-
-* `UNBOUNDED PRECEDING`: 分区的第一行
-* `UNBOUNDED FOLLOWING`: 分区的最后一行
-* `CURRENT ROW`: 当前行
-* `n PRECEDING`: 当前行之前的第n行（ROWS）或值-n的行（RANGE）
-* `n FOLLOWING`: 当前行之后的第n行（ROWS）或值+n的行（RANGE）
-
-***
-
-## 常用窗口函数分类
-
-### 聚合函数
-
-* `SUM()`, `AVG()`, `COUNT()`, `MAX()`, `MIN()`
-
-### 排名函数
-
-* `ROW_NUMBER()`: 连续唯一行号
-* `RANK()`: 相同值同排名，有间隔
-* `DENSE_RANK()`: 相同值同排名，无间隔
-* `PERCENT_RANK()`: 百分比排名
-* `NTILE(n)`: 将数据分成n个桶
-* `CUME_DIST()`: 累积分布值
-
-### 取值函数
-
-* `LAG()`: 访问前面的行
-* `LEAD()`: 访问后面的行
-* `FIRST_VALUE()`: 窗口第一个值
-* `LAST_VALUE()`: 窗口最后一个值
-* `NTH_VALUE()`: 窗口第n个值
-
-***
-
-## 最佳实践
-
-### 1. 使用WINDOW子句提高可读性
-
-❌ **不推荐**（重复定义窗口）:
-
-```sql
-SELECT month,
-       SUM(sales) OVER (ORDER BY month ROWS BETWEEN 2 PRECEDING AND CURRENT ROW),
-       AVG(sales) OVER (ORDER BY month ROWS BETWEEN 2 PRECEDING AND CURRENT ROW)
-FROM sales;
-```
-
-✅ **推荐**（使用WINDOW子句）:
-
-```sql
-SELECT month,
-       SUM(sales) OVER w,
-       AVG(sales) OVER w
-FROM sales
-WINDOW w AS (ORDER BY month ROWS BETWEEN 2 PRECEDING AND CURRENT ROW);
-```
-
-### 2. 合理使用PARTITION BY
-
-对于分组分析，使用PARTITION BY可以在不破坏数据结构的情况下进行组内计算：
-
-```sql
--- 示例：按类别分别计算排名
-SELECT category, month, sales,
-       RANK() OVER w AS rank_in_category
-FROM sales_by_category
-WINDOW w AS (PARTITION BY category ORDER BY sales DESC);
-```
-
-**执行结果**:
-
-```
-+-------------+-------+-------+------------------+
-| category    | month | sales | rank_in_category |
-+-------------+-------+-------+------------------+
-| Clothing    | 2     | 600   | 1                |
-| Clothing    | 3     | 550   | 2                |
-| Clothing    | 1     | 500   | 3                |
-| Electronics | 2     | 1200  | 1                |
-| Electronics | 1     | 1000  | 2                |
-| Electronics | 3     | 900   | 3                |
-+-------------+-------+-------+------------------+
-```
-
-说明：每个类别内独立计算排名，互不影响。
-
-### 3. 注意LAST\_VALUE的窗口范围
-
-如果要获取真正的最后一个值，必须使用`UNBOUNDED FOLLOWING`：
-
-```sql
-WINDOW w AS (ORDER BY month ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING)
-```
-
-### 4. 特定注意事项
-
-在Lakehouse中，建议在查询末尾添加LIMIT子句以提高性能：
-
-```sql
-SELECT ... FROM ... WINDOW ... LIMIT 50;
-```
-
-***
-
-## 性能优化建议
-
-1. **索引优化**: 在ORDER BY和PARTITION BY使用的列上创建适当的索引
-2. **窗口范围**: 尽量使用较小的窗口范围以减少计算量
-3. **复用窗口定义**: 使用WINDOW子句避免重复定义相同窗口
-4. **分区策略**: 合理使用PARTITION BY减少每个窗口的数据量
-
-***
-
-## 常见问题
-
-### Q1: WINDOW子句必须放在哪里？
-
-A: WINDOW子句必须放在FROM和WHERE子句之后，ORDER BY子句之前。
-
-### Q2: 能否在同一个查询中定义多个窗口？
-
-A: 可以，使用逗号分隔多个窗口定义。
-
-### Q3: ROWS和RANGE的主要区别是什么？
-
-A: ROWS基于物理行数，RANGE基于值的逻辑范围。当有重复值时，RANGE会包含所有具有相同值的行。
-
-### Q4: 为什么LAST\_VALUE没有返回预期的最后一个值？
-
-A: 需要显式指定`ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING`来包含整个分区。

-## 功能介绍
-公用表表达式（CTE，Common Table Expression）是一种在单个 SQL 查询中定义的临时结果集，其作用范围仅限于定义它的查询语句。CTE 的主要优点在于可以提高 SQL 语句的可读性和重用性。
-
-## 语法结构
-```
-WITH
-    <cte_name1> AS (SELECT ...),
-    [<cte_name2> AS (SELECT ...)],
-    [<cte_nameN> AS (SELECT ...)]
-SELECT ...
-```
-
-**参数说明：**
-
-- `<cte_name>`：指定公用表表达式的名称，用于在查询中引用。
-
-## 使用示例
-
-**示例1：简单的CTE查询**
-
-假设我们有一个名为 `orders` 的表，包含 `album_name` 和 `album_year` 两个字段。我们想要查询1976年发行的所有专辑名称，并按名称排序。使用CTE可以简化查询语句，如下所示：
-
-```sql
-WITH
-my_cte AS (SELECT * FROM orders WHERE album_year = 1976),
-my_cte2 AS (SELECT album_name,count(*) FROM my_cte group by album_name)
-SELECT album_name FROM my_cte2 ORDER BY album_name;
-```
-
-**示例2：带过滤条件的CTE查询**
-
-如果我们想查询1976年发行的专辑名称，但仅限于某个特定歌手的作品，可以在CTE中添加过滤条件：
-
-```sql
-WITH my_cte AS (SELECT * FROM orders WHERE album_year = 1976 AND artist = 'ArtistName')
-SELECT album_name FROM my_cte ORDER BY album_name;
-```

-# Lakehouse Zettapark
-
-Zettapark 是一个用于处理云器 Lakehouse 数据的 Python 库。它提供了一个高级的 Python API，用于在云器 Lakehouse 中执行 SQL 查询、操作数据和处理结果。Zettapark 使得在 Python 中使用云器 Lakehouse 变得更加简单和高效。你可以使用 Zettapark 执行 SQL 查询、操作数据和处理结果，就像在 Python 中使用 pandas 一样。
-
-你也可以[下载对应的Jupyter Notebook文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/Zettapark/Zettapark_quickstart.ipynb)，方便直接运行本 Demo。
-
-在 Zettapark 中执行 pandas 操作，会被翻译成 SQL 在云器 Lakehouse 中执行，从而实现分布式计算。
-
-比如以下 Python 代码：
-
-< 10)
-```
-
-在云器 Lakehouse 里执行的 SQL 是：
-
-```
-SELECT a, b FROM ( SELECT col1 AS a, col2 AS b FROM  VALUES (CAST(1 AS INT), CAST(3 AS INT)), (CAST(2 AS INT), CAST(10 AS INT))) WHERE ((a + b) < CAST(10 AS INT)) LIMIT 10;
-```
-
-## 安装clickzetta\_zettapark\_python
-
-```
-!pip install -q --upgrade clickzetta_zettapark_python -i https://pypi.tuna.tsinghua.edu.cn/simple
-```
-
-## 创建会话
-
-使用Zettapark的第一步是与ClickZetta Lakehouse建立会话。
-
-导入Session类。
-
-```python
-from clickzetta.zettapark.session import Session
-```
-
-和ClickZetta Connector for Python一样，Zettapark的函数中使用的相同参数（例如service、instance、用户名等）与云器Lakehouse建立会话建立会话。
-dict构造一个包含这些参数的名称和值的字典 (username、password、service、instance、workspace、schema等）。
-
-要创建会话包括如下：
-
-```
-创建一个 Python 字典 ( dict)，其中包含用于连接到 ClickZetta Lakehouse 的参数的名称和值。
-
-将此字典传递给Session.builder.configs方法以返回具有这些连接参数的构建器对象。
-
-create调用的方法建立builder会话。
-```
-
-以下示例使用dict包含连接参数来创建新会话：
-
-```
-hints = dict()
-hints['sdk.job.timeout'] = 3
-hints['query_tag'] = 'test_conn_hints_zettapark'
-connection_parameters = {
-  "username": "",
-  "password": "",
-  "service": "<region\_id>
-
-验证会话是否创建成功：
-
-```python
-df = session.sql("show schemas;")
-df.show(5)
-```
-
-```
----------------------------
-|`schema_name`            |
----------------------------
-|automobile               |
-|automv_schema            |
-|brazilianecommerce       |
-|continues_computing      |
-|continues_pipeline_demo  |
----------------------------
-```
-
-## 在 Zettapark Python 中使用 DataFrame
-
-在 Zettapark 中，查询和处理数据的主要方式是通过 DataFrame。本主题介绍如何使用 DataFrame。
-
-要检索和操作云器 Lakehouse Table 里的数据，请使用 DataFrame 类。DataFrame 表示延迟评估的关系数据集：它仅在触发特定操作时执行计算。
-
-要将数据检索到 DataFrame 中：
-
-```
-1，构造一个 DataFrame，指定 dataset 的数据源。
-
-例如，您可以创建一个 DataFrame 来保存来自表、外部 CSV 文件、本地数据或 SQL 语句执行的数据。
-
-2，指定如何转换DataFrame中的数据集。
-
-例如，您可以指定应该选择哪些列、如何过滤行、如何对结果进行排序和分组等。
-
-3，执行语句将数据检索到 DataFrame 中。
-
-为了将数据检索到 DataFrame 中，您必须调用执行操作的方法（例如，方法 collect()）。
-```
-
-本示例使用 DataFrame 来查询名为 `sample_product_data` 的表。如果要运行这些示例，您可以创建该表，并通过执行以下 SQL 语句向该表插入一些数据。
-
-```python
-session.sql('CREATE  TABLE if not exists sample_product_data (id INT, parent_id INT, category_id INT, name STRING, serial_number STRING, key INT, third INT)').collect()
-```
-
-```
-[Row(result_message='OPERATION SUCCEED')]
-```
-
-```python
-session.sql('CREATE  TABLE if not exists sample_product_data_varchar (id INT, parent_id INT, category_id INT, name STRING, serial_number VARCHAR, key INT, third INT)').collect()
-```
-
-```
-[Row(result_message='OPERATION SUCCEED')]
-```
-
-```python
-session.sql("""
-... INSERT INTO sample_product_data_varchar VALUES
-... (1, 0, 5, 'Product 1', 'prod-1', 1, 10),
-... (2, 1, 5, 'Product 1A', 'prod-1-A', 1, 20),
-... (3, 1, 5, 'Product 1B', 'prod-1-B', 1, 30),
-... (4, 0, 10, 'Product 2', 'prod-2', 2, 40),
-... (5, 4, 10, 'Product 2A', 'prod-2-A', 2, 50),
-... (6, 4, 10, 'Product 2B', 'prod-2-B', 2, 60),
-... (7, 0, 20, 'Product 3', 'prod-3', 3, 70),
-... (8, 7, 20, 'Product 3A', 'prod-3-A', 3, 80),
-... (9, 7, 20, 'Product 3B', 'prod-3-B', 3, 90),
-... (10, 0, 50, 'Product 4', 'prod-4', 4, 100),
-... (11, 10, 50, 'Product 4A', 'prod-4-A', 4, 100),
-... (12, 10, 50, 'Product 4B', 'prod-4-B', 4, 100)
-... """).collect()
-```
-
-```
-[Row(result_message='OPERATION SUCCEED')]
-```
-
-验证数据插入是否成功，请运行：
-
-```python
-session.sql("SELECT count(*) FROM sample_product_data_varchar").collect()
-```
-
-```
-[Row(`count`(*)=120)]
-```
-
-## 构建 DataFrame
-
-要构造 DataFrame，可以使用 Session 类的方法和属性。以下每种方法都从不同类型的数据源构造 DataFrame。
-
-要从表、视图或流中的数据创建 DataFrame，请调用以下 `table` 方法：
-
-```python
-# Create a DataFrame from the data in the "sample_product_data" table.
-df_table = session.table("sample_product_data")
-# To print out the first 10 rows
-df_table.show()
-```
-
-```

----------------------------------------------------------------------------------------
-```
-
-```python
-# Create a DataFrame from the data in the "sample_product_data" table.

----------------------------------------------------------------------------------------
-```
-
-要从指定数据创建 DataFrame，请调用 `create_dataframe` 方法：
-
-```python
-# Create a DataFrame with one column named a from specified values.
-df1 = session.create_dataframe([1, 2, 3, 4]).to_df("a")
-df1.show()
-
-```
-
-```
--------
-|`a`  |
--------
-|1    |
-|2    |
-|3    |
-|4    |
--------
-```
-
-创建一个具有 4 列（“a”、“b”、“c”和“d”）的 DataFrame：
-
-```python
-df2 = session.create_dataframe([[1, 2, 3, 4]], schema=["a", "b", "c", "d"])
-df2.show()
-```
-
-```
--------------------------
-|`a`  |`b`  |`c`  |`d`  |
--------------------------
-|1    |2    |3    |4    |
--------------------------
-```
-
-创建另一个包含 4 列（“a”、“b”、“c”和“d”）的 DataFrame：
-
-```python
-from clickzetta.zettapark import Row
-df3 = session.create_dataframe([Row(a=1, b=2, c=3, d=4)])
-df3.show()
-```
-
-```
--------------------------
-|`a`  |`b`  |`c`  |`d`  |
--------------------------
-|1    |2    |3    |4    |
--------------------------
-```
-
-创建一个 DataFrame 并指定一个模式（Schema）：
-
-```python
-from clickzetta.zettapark.types import IntegerType, StringType, StructType, StructField
-schema = StructType([StructField("a", IntegerType()), StructField("b", StringType())])
-df4 = session.create_dataframe([[1, "click"], [3, "zetta"]], schema)
-df4.show()
-```
-
-```
----------------
-|`a`  |`b`    |
----------------
-|1    |click  |
-|3    |zetta  |
----------------
-```
-
-要创建包含一系列值的 DataFrame，请调用以下 `range` 方法：
-
-```python
-df_range = session.range(1, 10, 2).to_df("a")
-df_range.show()
-```
-
-```
--------
-|`a`  |
--------
-|1    |
-|3    |
-|5    |
-|7    |
-|9    |
--------
-```
-
-## 对指定数据集进行转换
-
-要指定选择哪些列以及如何对结果进行筛选、排序、分组等操作，请调用转换数据集的 DataFrame 方法。要标识这些方法中的列，请使用 `col` 函数或计算结果为列的表达式。
-
-例如：
-要指定应返回哪些行，请调用 `filter` 方法：
-
-```python
-from clickzetta.zettapark import functions as F
-```
-
-```python
-df = session.table("sample_product_data").filter(F.col("id") == 1)
-df.show()
-```
-
-```
---------------------------------------------------------------------------------------
-|`id`  |`parent_id`  |`category_id`  |`name`     |`serial_number`  |`key`  |`third`  |
---------------------------------------------------------------------------------------
-|1     |0            |5              |Product 1  |prod-1           |1      |10       |
---------------------------------------------------------------------------------------
-```
-
-要指定应选择的列，请调用 `select` 方法：
-
-```python
-# Create a DataFrame that contains the id, name, and serial_number
-# columns in the "sample_product_data" table.
-df = session.table("sample_product_data").select(F.col("id"), F.col("name"), F.col("serial_number"))
-df.show()
-```
-
-```
----------------------------------------
-|`id`  |`name`      |`serial_number`  |
----------------------------------------
-|1     |Product 1   |prod-1           |
-|2     |Product 1A  |prod-1-A         |
-|3     |Product 1B  |prod-1-B         |
-|4     |Product 2   |prod-2           |
-|5     |Product 2A  |prod-2-A         |
-|6     |Product 2B  |prod-2-B         |
-|7     |Product 3   |prod-3           |
-|8     |Product 3A  |prod-3-A         |
-|9     |Product 3B  |prod-3-B         |
-|10    |Product 4   |prod-4           |
----------------------------------------
-```
-
-```python
-# Import the col function from the functions module.
-df_product_info = session.table("sample_product_data")
-df1 = df_product_info.select(df_product_info["id"], df_product_info["name"], df_product_info["serial_number"])
-df2 = df_product_info.select(df_product_info.id, df_product_info.name, df_product_info.serial_number)
-df3 = df_product_info.select("id", "name", "serial_number")
-```
-
-## 连接DataFrame
-
-要连接 DataFrame 对象，请调用 `join` 方法：
-
-```
-# Create two DataFrames to join
-df_lhs = session.create_dataframe([["a", 1], ["b", 2]], schema=["key", "value1"])
-df_rhs = session.create_dataframe([["a", 3], ["b", 4]], schema=["key", "value2"])
-# Create a DataFrame that joins the two DataFrames
-# on the column named "key".
-df_lhs.join(df_rhs, df_lhs.col("key") == df_rhs.col("key")).select(df_lhs["key"].as_("key"), "value1", "value2").show()
-```
-
-```
--------------------------------
-|`key`  |`value1`  |`value2`  |
--------------------------------
-|a      |1         |3         |
-|b      |2         |4         |
--------------------------------
-```
-
-```python
-import copy
-
-df = session.table("sample_product_data")
-# This fails because columns named "id" and "parent_id"
-# are in the left and right DataFrames in the join.
-df_copy = copy.copy(df)
-df_joined = df.join(df_copy, F.col("id") == F.col("parent_id"))
-```
-
-## 指定列和表达式
-
-调用这些转换方法时，您可能需要指定列或使用列的表达式。例如，调用 `select` 方法时，您需要指定要选择的列。
-
-```python
-df_product_info = session.table("sample_product_data").select(F.col("id"), F.col("name"))
-df_product_info.show()
-```
-
-```
----------------------
-|`id`  |`name`      |
----------------------
-|1     |Product 1   |
-|2     |Product 1A  |
-|3     |Product 1B  |
-|4     |Product 2   |
-|5     |Product 2A  |
-|6     |Product 2B  |
-|7     |Product 3   |
-|8     |Product 3A  |
-|9     |Product 3B  |
-|10    |Product 4   |
----------------------
-```
-
-在指定过滤器、投影、连接条件等时，可以在表达式中使用 Column 对象。例如：
-您可以使用 Column 对象和 `filter` 方法来指定过滤条件：
-
-```python
-# Specify the equivalent of "WHERE id = 20"
-# in a SQL SELECT statement.
-df_filtered = df_product_info.filter(F.col("id") == 20)
-df_filtered.show()
-```
-
-```
------------------
-|`id`  |`name`  |
------------------
-|      |        |
------------------
-```
-
-```python
-df = session.create_dataframe([[1, 3], [2, 10]], schema=["a", "b"])
-# Specify the equivalent of "WHERE a + b < 10"
-# in a SQL SELECT statement.
-df_filtered = df.filter((F.col("a") + F.col("b")) < 10)
-df_filtered.show()
-```
-
-```
--------------
-|`a`  |`b`  |
--------------
-|1    |3    |
--------------
-```
-
-## 关闭会话
-
-```Python
-session.close()
-```

-# 基于 Lakehouse Zettapark 进行数据工程 Data Engineering
-
-这是一个非常基础的数据工程示例，演示了如何通过云器 Zettapark Python 代码进行读取、分组和写入数据等基本 DataFrame 操作。本示例使用云器Lakehouse内置的免费示例数据库（clickzetta\_sample\_data.tpch\_100g）作为数据源。
-
-步骤如下：
-
-```
-1，通过Zettapark连接到云器Lakehouse
-
-2，通过SupplierKey连接 2个大型表 (LINEITEMS 有 6亿行 & SUPPLIER 有 100 万行)
-
-3，通过将虚拟计算集群调整到不同规格来演示按需扩展
-
-4，对比不同规格的虚拟计算集群对同一个任务的执行时间的不同
-
-    汇总供应商和零件编号的数据以计算总和、最小值和最大值（3500万行）
-
-    将结果数据框写入云器Lakehouse物理表（8000万行）

-# **Zettapark 相对于 Spark 和 PySpark 的优势**
-
-*   **迁移快捷**：代码与 Spark/PySpark 基本相同，无需重新学习新语言。
-*   **更便宜**：计算完全 Serverless 化，可以秒级扩缩容（向上/向下），并且仅在使用时运行（产生成本）。
-*   **秒级即时扩缩容**：同样的计算任务，XSMALL 规格的虚拟计算集群 (VCluster) 需要约 75 秒，而 MEDIUM 规格的仅需约 20 秒。
-*   **更快**：消除了所有不必要的数据移动，计算时间更短，成本更低。
-*   **更易使用**：意味着更少的人力投入，因为计算和存储几乎无需维护。

-# 配置访问控制
-
-本文介绍如何在云器Lakehouse中为账户和元数据对象配置访问控制策略。通过合理配置访问控制，你可以确保数据与对象的访问仅限于授权用户与角色，符合最小权限原则，提升系统安全性。
-
-## 服务实例级管理
-
-### 为服务实例（instance）指定额外的管理员用户
-
-在云器Lakehouse中，创建服务实例的用户默认拥有“实例管理员”（instance\_admin）角色。为确保至少有一名用户可执行实例层面的管理任务（如创建工作空间、管理实例级角色），当你移除被授予“实例管理员”（instance\_admin）角色的用户时至少需要保留一名用户，否则会收到报错提示。建议至少再指定一名用户为实例管理员，以避免因用户不可用或其他特殊情况造成的影响。
-
-^
-
-### 授予实例级别角色
-
-服务实例级别的角色仅支持通过Web端方式授予。仅具备“服务实例管理员”（instance\_admin）角色的用户可进行此操作。
-
-在服务实例中，依次打开“管理”->“安全”菜单，点击进入，并切换到“角色”页面。
-
-:-: ![](.topwrite/assets/image_1734853864093.png =791)
-
-点击需要授予的服务实例角色，进入该角色的详情页面，点击“用户授予”：
-
-:-: ![](.topwrite/assets/image_1734853972562.png =793)
-
-在弹窗中勾选需要授予的用户，点击“授权”按钮，即可完成实例角色的授予。
-
-^
-
-## 工作空间级管理
-
-### 指定工作空间（workspace）管理员
-
-创建工作空间（workspace）的用户默认拥有该工作空间的"工作空间管理员（workspace\_admin）"角色，该角色具备管理工作空间内的所有权限。每个工作空间内至少需要有一名用户被授予工作空间管理员角色，可以有多个用户被同时授予。
-
-### 管理工作空间内角色和成员
-
-每个工作空间内的角色和成员是与其他工作空间独立的，需要单独授予。仅一个工作空间的工作空间管理员（workspace\_admin）角色，可以管理该工作空间内的角色授予、创建、删除，以及空间内成员的添加、移除。
-
-#### 管理空间成员
-
-一个用户若要在指定工作空间内使用计算集群（Vcluster）和执行SQL，其前提条件是加入该工作空间。工作空间管理员可以通过以下两种方式将指定用户加入工作空间中：
-
-**Web端操作**
-
-进入服务实例后，依次点击菜单中的“管理”-“工作空间”，进入工作空间列表。点击工作空间名称，进入需要添加成员的工作空间详情。
-
-:-: ![](.topwrite/assets/image_1734854163713.png =795)
-
-在工作空间详情页点击“+ 添加用户” 按钮，在弹窗中选择需要添加的用户。只有服务实例中已存在且当前未加入此工作空间的用户才会在列表中显示。勾选一到多名用户，随后点击“添加用户”或“添加用户并授予角色”按钮，将已选择用户添加进入工作空间。成功添加后，可在工作空间的“用户”列表中找到新添加的用户。
-
-在工作空间的“用户”列表中，点击某一用户右侧操作列的“...”，选择“移除用户”，将从工作空间中移除该用户。被移除的用户将立即失去被授予的空间角色，并失去使用工作空间内计算集群（Vcluster）和在该工作空间内执行SQL的权限。

-
-请注意，从工作空间移除的用户，仍将具备被直接授予给用户的数据权限，即可以在其他工作空间行使被授予的数据权限，对数据进行查询或变更。因此，推荐通过授予角色的方式来管理权限，以降低此类场景带来的权限管理难度。
-
-**SQL操作**
-
-通过JDBC连接工作空间，为工作空间添加用户时执行以下语句：
-
-```SQL
-CREATE USER <user_name>;
-```
-
-\<user\_name>替换为需要加入工作空间的用户名。仅支持添加服务实例中已存在且当前没有加入此工作空间的用户。
-
-从工作空间移除用户执行以下语句：
-
-```SQL
-DROP USER <user_name>;
-```
-
-\<user\_name>替换为需要移除工作空间的用户名。该操作不会删除此用户身份，只会从当前工作空间中移除此用户。
-
-### 使用工作空间级别角色
-
-#### 在工作空间内进行开发
-
-在工作空间中进行开发需要：具备在工作空间中执行SQL的权限（成为工作空间成员后获得）；具备使用工作空间中计算资源的权限；具备需要操作的数据对象的权限。
-
-在每个工作空间中预置了以下角色默认具备以上的一种或多种权限，可将以下角色授予用户，以快速开始数据开发。
-
-**工作空间开发者（workspace\_dev）角色**
-
-workspace\_dev角色默认具备工作空间内所有数据对象（table、view、dynamic table等，详见'元数据对象'）的读写权限，默认具备工作空间内所有计算集群的使用权限。
-
-用户被授予workspace\_dev角色后，可直接在Web页面的"开发"功能内或使用JDBC协议进行数据开发。
-
-注意，workspace\_dev角色默认具备的数据对象读写权限并不支持其将权限二次授权。如需授予其他角色数据对象的读或写权限，请使用具备工作空间管理员（workspace\_admin）角色的用户进行操作。
-
-**数据分析师（workspace\_analyst）角色**
-
-workspace\_analyst角色默认具备工作空间内所有计算集群的使用权限，默认具备工作空间内所有数据对象（table、view、dynamic table等）的read metadata（元数据查看）权限，但是不具备数据对象的select权限，即不能对任何的表或视图执行select查询。使用workspace\_analyst角色进行数据查询分析时，需要授予workspace\_analyst角色要查询数据对象的select权限，以执行数据查询操作。
-
-对workspace\_analyst角色的数据授权操作，请参考“GRANT”语句操作文档。
-
-**使用自定义角色或用户**
-
-自定义角色和用户通过授权，也可在工作空间中执行SQL语句进行开发或数据查询分析，但无法使用Web端的“开发”功能。对自定义角色和用户的授权需要具备workspace\_admin角色的用户进行操作。授权可参考以下语句：
-
-```SQL
---将工作空间内所有计算集群的使用和元数据查看权限授予自定义角色
-GRANT USE, READ METADATA ON ALL VCLUSTERS TO ROLE <CUSTOM_ROLE_NAME>;
---[可选]将指定名称的计算集群的使用和元数据查看权限授予自定义角色
-GRANT USE, READ METADATA ON  VCLUSTER <VCLUSTER_NAME> TO ROLE <CUSTOM_ROLE_NAME>;
-
---将指定名称的schema下所有对象的select和元数据查询权限授予自定义角色
-GRANT SELECT, READ METADATA ON ALL OBJECTS IN SCHEMA <SCHEMA_NAME> TO ROLE <CUSTOM_ROLE_NAME>;
---将指定table的select和元数据查询权限授予自定义角色
-GRANT SELECT, READ METADATA ON TABLE <TABLE_NAME> TO ROLE <CUSTOM_ROLE_NAME>;
-```
-
-对用户授权时，将上述语句中的 TO ROLE <CUSTOM_ROLE_NAME> 替换为 TO USER <USER_NAME> 即可。
-
-#### 提交并运维工作空间调度任务
-
-在工作空间中提交调度任务只能在Web端的“开发”功能中完成。workspace\_admin(工作空间管理员)和workspace\_dev（工作空间开发者）角色具备“提交”作业脚本成为调度任务的权限。
-
-:-: ![](.topwrite/assets/image_1734876961826.png =802)
-
-^
-
-工作空间中运维调度任务的系统角色为：workspace\_sre（工作空间运维）。具备该角色的用户，可在“运维监控”菜单下的“**任务运维**”和”**监控报警**“功能以及”数据“菜单下的”**数据质量**“功能中，对其所在空间的调度任务进行管理操作。
-
-workspace\_sre（工作空间运维）角色具备该角色所在工作空间下所有调度任务的运维管理权限，不具备工作空间下的计算资源使用和数据对象查询权限。
-
-如需对服务实例内所有工作空间的调度任务进行统一管理，可对用户授予实例级别角色：instance\_sre（实例运维）角色。该角色的权限是服务实例内所有workspace\_sre角色默认权限的并集。
-
-#### 创建自定义角色
-
-为实践“最小权限原则”，建议根据你的组织业务职能划分创建自定义角色，并为其分配针对特定对象和操作的权限。这样，你可以精确控制用户对特定数据或对象的访问范围。
-
-创建自定义角色的一般流程：
-
-1. 创建自定义角色（CREATE ROLE语句）。
-2. 为该角色授予所需的权限点（GRANT语句）。
-3. 将该角色授予给需要相关权限的用户（GRANT ROLE语句或Web端操作）。
-
-**注意**：云器Lakehouse中，角色不能被授予给其他角色，即不支持角色层次结构（Role Hierarchy）。所有角色最终直接授予给用户，避免了因角色间的层级继承关系而带来的、判断具体用户权限范围的复杂度。
-
-#### 授予或移除用户的角色
-
-你可以使用Web或执行授权SQL的操作方式向用户授予或移除角色。仅具备服务实例管理员（instance\_admin）或工作空间管理员（workspace\_admin）角色的用户，可以为用户授予或移除角色。服务实例管理员（instance\_admin）具备向服务实例内所有用户授予实例级别角色的权限；工作空间管理员（workspace\_admin）具备向工作空间内成员授予空间内角色的权限。
-
-**Web端操作**
-
-在“安全”-“角色”页面，可以查看当前实例下的服务实例级别角色和工作空间级别角色。
-
-:-: ![](.topwrite/assets/image_1734878372389.png =784)
-
-服务实例管理员（instance\_admin）角色可查看所有的实例级别角色和所有工作空间级别角色，可管理所有实例级别角色的授权；
-
-工作空间管理员（workspace\_admin）角色可查看本工作空间内的所有工作空间角色，并管理这些角色的授权。如一个用户同时具备多个工作空间的工作空间管理员（workspace\_admin）角色，则可以同时管理多个工作空间内的角色授权。
-
-对任一角色授权时，点击该角色名称，进入角色详情页，此时可以查看该角色已被授予的所有用户。点击“+ 用户授予”，在弹窗中勾选需要添加的用户，点击“授权”，即可将角色授予用户。
-:-: ![](.topwrite/assets/image_1734878510613.png =798)
-
-移除角色被授予的用户时，点击用户名右侧的"..."，选择“移除用户”，即可取消该用户使用这个角色的权限。
-
-在“管理”-“工作空间”列表进入工作空间详情页面，在“角色”页签也可以查看该空间内的角色列表，并通过上述操作将该角色授予或取消授予用户。
-
-:-: ![](.topwrite/assets/image_1734878871234.png =795)
-
-***
-
-**SQL端操作**
-
-仅工作空间级别的用户支持使用SQL操作进行授权。在工作空间内执行以下语句，可将空间内的角色授予指定用户。
-
-```SQL
-Grant ROLE <ROLE_NAME> TO USER <USER_NAME>;
-```
-
-执行以下语句可移除角色中的指定用户；
-
-```SQL
-REVOKE ROLE <ROLE_NAME> FROM USER <USER_NAME>;
-```
-
-### 示例：创建自定义角色并授予权限
-
-**提示**：当前暂不支持在 Web 端创建自定义角色和对自定义角色授权。你需要使用 SQL 创建自定义角色。
-
-假设你希望创建一个空间级角色r1，用于管理特定schema s1下的一张表t1。为此，需要为r1授予：
-
-* 对计算集群（假设名称为v1）的使用权限（USAGE）。
-* \[可选] 计算集群（假设名称为 v1）的 READ METADATA 权限，以在计算集群页面或 SHOW VCLUSTERS 结果中可见这个计算集群；
-* 对表s1.t1的ALL权限，以对表执行select、insert、update、alter等操作。
-
-#### 创建自定义角色
-
-```
-CREATE ROLE r1;
-```
-
-#### 为角色授予权限
-
-```
--- 为r1角色授予对计算集群（假设名称为v1）的使用权限（USAGE）
-GRANT use ON VCLUSTER v1 TO ROLE r1;
---[可选]为r1角色授予对计算集群（假设名称为v1）的read metadata权限
-GRANT read metadata ON VCLUSTER v1 TO ROLE r1;
-
-
---为r1角色授予对表s1.t1的所有权限
-GRANT all ON table s1.t1 to ROLE r1;
-
-```
-
-#### 将角色授予给用户
-
-```
-GRANT ROLE r1 TO USER u1;
-```
-
-### 示例：创建只读角色
-
-若你需要一个角色仅能对某schema中所有表进行查询（只读访问），可按照与创建自定义角色相同的流程操作。区别在于这个场景下仅授予表的SELECT和READ METADATA权限，而不包含任何写入、修改、删除等权限。同时，这里使用 `ALL TABLES IN SCHEMA s1` 来表达 s1 下当前和未来的所有 table 对象，以简化授权表达。
-
-例如，为read\_only角色授予schema s1下所有表的SELECT和READ METADATA权限：
-
-```
-GRANT SELECT, READ METADATA ON ALL TABLES IN SCHEMA s1 TO ROLE read_only;
-```
-
-请注意，如果read\_only角色没有计算集群的使用权限，此时无法使用计算资源对table执行查询。所以还需要至少授予该角色1个计算集群（vcluster）的使用权限。
-
-例如，为read\_only角色授予名称为demo\_vcluster的计算集群的使用权限。
-
-```
-GRANT USE ON VCLUSTER demo_vcluster TO ROLE read_only;
-```
-
-### 查看已授予的权限
-
-使用SHOW GRANTS命令可查看某对象或角色的当前权限状况。例如：
-
-```
--- 查看schema d1.s1上的已授予权限
-SHOW GRANTS ON SCHEMA d1.s1;
-
--- 查看角色r1获得的权限
-SHOW GRANTS TO ROLE r1;
-
--- 查看用户smith获得的权限和角色
-SHOW GRANTS TO USER smith;
-```

-# 访问控制概览
-
-本文介绍了云器Lakehouse的访问控制总体框架和关键概念。通过了解访问控制的核心原理和相关要素，用户与管理员可在云器Lakehouse平台中安全、灵活地分配与管理权限，从而确保数据与元数据对象的合规使用。
-
-## 1. 访问控制模型
-
-云器Lakehouse采用灵活的访问控制机制，支持两种主要模型：
-
-* **访问控制列表（ACL）**： 将权限直接分配给用户（User）。在小型或简单场景中，这种方式较为直观；但在大型环境中，管理难度会随用户数量及权限需求增加而上升。
-
-:-: ![](.topwrite/assets/ACL.png =391)
-
-* **基于角色的访问控制（RBAC）**： 首先为角色（Role）分配权限，然后将角色授予用户，从而实现权限的间接管理。RBAC有助于简化复杂环境下的权限维护。当业务需求变化时，只需在角色层面调整权限，而无需为每个用户单独维护。
-
-:-: ![](<.topwrite/assets/Untitled Diagram.drawio.png> =460)
-
-与传统的DAC（Discretionary Access Control）不同，云器Lakehouse不直接支持在对象所有者基础上继续二次授权的DAC模式。建议采用RBAC，对权限进行集中、可控的统一管理。
-
-在云器Lakehouse中，RBAC和ACL的授权方式是并存的。一个用户可以同时被直接授予多个权限，并同时被授予多个角色。当该用户在执行任何操作时，其权限范围均为其被“直接授予的权限”和“被授予的角色”权限之和。用户无需声明其当前以何种身份或角色行使操作，鉴权系统将遍历该用户所有当前拥有的权限并给出鉴权结果。
-
-## 2. 对象及其所有权
-
-### 对象（Object）
-
-元数据对象是可被授予权限的实体，包括工作空间（workspace）、schema、table、view、virtual cluster等。这些对象在创建后默认由创建者拥有其全部权限，但无法依此进行二次授权。访问对象时，如果未被显式授权，则默认拒绝。
-
-云器Lakehouse中所有的元数据对象，详见授权文档。
-
-### 对象所有权（Ownership）
-
-初始创建该对象的用户（user）拥有对象的所有权（ownership）。拥有对象的角色可以对对象执行包括修改、删除在内的全部操作。当前暂不支持对对象所有权的转移。
-
-为了实现更灵活的权限分配机制和更安全的访问控制，推荐通过角色权限体系，使用服务实例管理员（instance\_admin）角色和工作空间管理员（workspace\_admin）角色进行统一的授权方式管理对象访问。
-
-## 3. 角色层次与类型
-
-### 角色（Role）
-
-角色是权限的载体。当为角色分配权限点后，通过将该角色授予给用户，可实现权限的间接传递。当用户拥有多个角色时，其权限为这些角色权限集合的并集。
-
-### 角色层次（Role Hierarchy）
-
-角色可分为两个层级范围：
-
-* **实例角色（Instance Role）**：用于实例级资源和操作的全局管控。
-* **工作空间角色（Workspace Role）**：作用于特定工作空间范围内的对象（如schema、table、virtual cluster等）。工作空间角色以工作空间为边界，互不影响。
-
-:-: ![](.topwrite/assets/role-levels.drawio.png =531)
-
-这种层次结构有助于在全局与局部范围实现精细的访问控制。当业务规模扩大、权限需求复杂时，可以通过在实例角色与工作空间角色间建立清晰的角色层次，简化权限分配。
-
-### 预置角色与自定义角色
-
-云器Lakehouse提供了若干预置角色（如实例管理员、数据源管理员、空间管理员等）以满足基础使用场景。用户还可在工作空间内创建自定义角色（通过SQL语句），从而灵活定义与调整符合自身业务需求的权限集。
-
-云器Lakehouse中所有的预置角色及其默认权限，详见授权文档。
-
-## 4. 权限及授权管理
-
-### 权限（Privilege）
-
-权限定义了对对象所能执行操作的最小访问单元，包括对表的查询、插入数据、对schema的管理或对虚拟集群的使用等。权限点可细粒度地定义用户对对象进行的读写改删操作。
-
-^
-
-云器Lakehouse中所有元数据对象及其权限点，详见授权文档。
-
-### 授权与回收（Grant & Revoke）
-
-使用 `GRANT` 与 `REVOKE` 命令对元数据对象授权或回收权限，权限变更即时生效。在Web界面中也可进行相应的可视化操作。
-
-示例：
-
-`GRANT SELECT ON TABLE my_table TO ROLE analyst_role;`
-
-`REVOKE INSERT ON TABLE my_table FROM ROLE analyst_role;`
-
-业务对象（如脚本、任务和数据质量规则）暂不支持SQL细粒度授权，其访问权限通过授予对应预置角色实现。
-
-## 无超级用户概念
-
-云器Lakehouse中不存在可绕过权限检查的超级用户（super-user）或超级角色（super-role）。所有访问操作都必须明确获得授权，确保数据访问的安全与合规。

-# 授权
-
-## 1. 访问控制模型
-
-云器Lakehouse的所有元数据对象均基于访问控制体系进行授权访问。云器Lakehouse支持的访问控制模型包括**访问控制列表**（ACL，Access Control List）和 **基于角色的访问控制**（RBAC，Role-Based Access Control）两种。
-
-* **访问控制列表**（**ACL，Access Control List**）
-
-权限点被直接授予用户（User）。
-
-* **基于角色的访问控制**（RBAC，Role-Based Access Control）
-
-权限点被授予角色（Role），用户通过被授予角色而获得相应的权限。
-
-* **DAC（Discretionary Access Control）模式兼容**
-
-云器Lakehouse不直接支持DAC模式。DAC模式指：元数据对象（table、view、virtual cluster等）的所有者（owner）默认拥有该元数据对象的所有权限，且可将权限授予其他主体。云器Lakehouse中的元数据对象被创建后，其创建者默认具备该对象的所有权限，但无法进行二次授权。
-
-^
-
-云器Lakehouse访问控制体系中的主要概念包括：
-
-* **元数据对象（Object）**
-
-元数据对象是一个可以被授出访问权限的实体。一个元数据对象包含多个权限点，除非通过明确授予允许，否则相关操作将被拒绝。
-
-* **角色（Role）**
-
-角色是一个可以被授予权限的实体。角色可以分配给用户，但不可以分配给其他角色。
-
-* **权限（Privilege）**
-
-权限是对元数据对象访问的最小定义级别。可以使用多个不同的权限点来控制授予操作的范围。
-
-* **用户（User）**
-
-用户是云器 Lakehouse 识别的用户身份，可以是用户身份或服务使用的身份。
-
-## 2. 角色
-
-### 2.1 角色类型
-
-云器Lakehouse中的角色两种：**预置角色**和**自定义角色**。
-
-为便于用户快速完成基本授权并使用产品功能，云器Lakehouse预置了多个角色。预置角色随服务实例创建而自动创建，不可修改权限或删除，但可以被授予用户。
-
-用户可根据自身需要，创建自定义角色，并对该角色授权。自定义角色可随时修改角色的属性、权限范围或删除。目前仅限在工作空间内创建自定义角色，不支持创建实例级别的自定义角色。
-
-### 2.2 角色级别
-
-云器Lakehouse的元数据对象分为“服务实例”（Instance）和“工作空间”（workspace）两个级别，角色也对应分为“实例角色”和“空间角色”两个级别。两个级别的对象没有从属关系，实例级别的角色不具备且不可被授予工作空间级别任何元数据对象（空间用户、空间角色、schema、table、计算集群等）的任何权限。
-
-空间角色以工作空间（workspace）为隔离边界。不同工作空间内，允许存在同名的角色。不同工作空间之间，不允许跨空间将权限授予另一工作空间角色。
-
-### 2.3 预置系统角色
-
-当前系统内预置的角色及权限如下表所示：
-
-|          |          |                    |                                                                                          |                                                        |                                 |
-| -------- | -------- | ------------------ | ---------------------------------------------------------------------------------------- | ------------------------------------------------------ | ------------------------------- |
-| **角色级别** | **角色名称** | **角色代码**           | **具备权限**                                                                                 | **角色说明**                                               | **默认授予**                        |

-
-### 2.4 用户自定义角色
-
-当前仅支持在工作空间内，使用SQL语法创建自定义角色。创建自定义角色的语法为：
-
-```Plain
-CREATE ROLE <role_name>;
-```
-
-仅被授予工作空间的空间管理员角色（workspace\_admin）的用户，可在工作空间内创建自定义角色，并可随时对自定义角色进行权限管理和删除操作。
-
-## 3. 权限（Privileges）
-
-### 3.1 权限定义
-
-访问控制权限的授予决定了用户可以对特定对象执行指定操作。对于云器Lakehouse中的每个元数据对象对象，都有一组可以授予的权限。云器Lakehouse中的所有元数据对象及其拥有的权限点，详见 权限点 文档。
-
-元数据对象有三种表达方式：
-
-1）以对象类型加对象名称，表达已被创建的对象。例如：table mytable（名称为mytable的表） 或 vcluster myvcluster（名称为myvcluster的计算集群）；
-
-2）以关键字ALL 加对象类别，表达现有和未来所有该类型的对象。例如：ALL tables in schema my\_schema （名称为my\_schema的schema下的所有table类型对象）；
-
-3）以关键字ALL 加关键字 OBJECTS 表达现有和未来的所有类型的所有对象，例如：ALL OBJECTS in workspace my\_workspace（名称为my\_workspace的工作空间下所有的对象）。
-
-权限点有两种表达方式：
-
-1）以具体权限点表达，例如：select，read metadata，update 等；
-
-2）以关键字ALL加关键字PRIVILEGES，表达所有权限点，例如：ALL PRIVILEGES on table mytable（mytable表的所有权限点）。
-
-在使用SQL语句进行权限管理时，使用 GRANT <权限点> 和 REVOKE <权限点> 命令。在GRANT <权限点>语句末尾加上with grant option，表示在授予该权限点的同时，将允许被授予者将该权限点再授予其他角色或用户。
-
-### 3.2 元数据对象
-
-Lakehouse中的元数据对象及其父级对象如下表所示：
-
-|                   |           |
-| ----------------- | --------- |
-| **元数据对象**         | **父级对象**  |
-| workpace          | instance  |
-| share             | instance  |
-| network policy    | instance  |
-| schema            | workspace |
-| virtual cluster   | workspace |
-| connction         | workspace |
-| table             | schema    |
-| view              | schema    |
-| materialized view | schema    |
-| dynamic table     | schema    |
-| table stream      | schema    |
-| volume            | schema    |
-| index             | schema    |
-| function          | schema    |
-| job               | schema    |
-
-元数据对象均可以通过SQL进行授权。
-
-### 3.3 业务对象
-
-除元数据对象外，在数据开发、数据治理过程中，产生了业务对象，如下表所示：
-
-|                    |                       |
-| ------------------ | --------------------- |
-| **业务对象**           | **业务类别**              |
-| 脚本（Script）         | 数据开发  （Development）   |
-| 任务和实例（task）        | 监控规则（monitor rules）   |
-|                    | 通知策略（announce policy） |
-| 数据质量（data quality） | 质量规则（dqc rule）        |
-
-业务对象不可通过SQL进行授权。用户通过被授予包含业务对象权限的预置角色来获取相关权限。暂不支持细粒度授权。
-
-### 3.4 ALL 对象
-
-ALL 对象是一种特殊的对象，表达一类对象下**当前**和**未来**的所有个体。例如：all tables表达当前和未来的所有table；all vclusters表达当前和未来的所有计算集群。
-
-通过`ALL`关键字可以一次性为对象集合（如某schema下的所有表）授予权限，从而减少繁琐的重复授权操作。同时，ALL关键字提供“Future Grants”（未来授权）机制，例如：`all tables in schema s1` 表示schema s1内当前和未来可能新增的所有table类型对象。
-
-ALL 对象在使用时，需要和关键字“in”一起使用，以明确ALL 对象描述的范围，关键字“in”之后跟随的是ALL 对象的父级对象。例如：all tables in schema my\_schema; all vclusters in workspace my\_workspace。
-
-ALL 对象的一种特殊用法是用于指代某父级对象下的所有自级对象，例如：all objects in schema my\_schema，表达my\_schema下的所有类型对象，包括table、view、functions等。
-
-注意：尽管ALL对象可以提升授权操作的效率，但请谨慎使用all objects的方式授权。仅在确认all objects指代的范围符合授权预期时，再使用all objects进行指代，避免授权范围超出预期。
-
-^
-
-### 3.5 权限点
-
-元数据对象的所有操作类型如下：
-
-|                  |          |                                                  |

-
-业务对象的所有操作类型如下：
-
-| **对象**                | **包含操作**                                                                                  |

-
-每个操作都与一个唯一的权限点相对应。当被授予某个对象的某权限点时，即可对该对象执行对应的操作。
-
-### 3.6 ALL 权限点
-
-ALL 权限点是各类元数据对象上均存在的一个权限点，表达该对象的所有权限点。ALL权限点是一个**独立**的权限点，与其他权限点并非指代关系。因此授予ALL权限点不会覆盖授予其他权限点，解除ALL权限点也不会解除其他权限点。
-
-例如：对user my\_user 先后授予了example\_table的select和ALL权限点。则此时my\_user用户由于被授予了ALL权限点，可以对example\_table执行所有操作；在查询my\_user用户对example\_table的权限时，显示同时拥有的select和all权限点的授权。当对my\_user用户解除ALL权限点的授权时，my\_user用户仍具备对example\_table进行select操作的权限。
-
-使用ALL权限点可以快速完成对一个对象所有权限的授予，例如：
-
-```SQL
-Grant all privileges on table example_table to user my_user;
-```
-
-## 4. 授权（Grants）
-
-### 4.1 授权定义
-
-授权的基本模型是将“**对象**”的“**权限点**”授予“**身份**”。其中对象可以是元数据对象或业务对象，权限点是这个对象包含的一个或多个权限点，身份目前指“用户（user）”和“角色（role）”两种。
-
-### 4.2 授权关系管理
-
-一个用户（user）可以通过两种方式获得某个对象的权限：1）直接被授予该对象的权限；2）通过被授予拥有该对象权限的角色获得。
-
-当一个用户同时被授予多个角色时，该用户的权限范围是多个角色权限范围的并集。
-
-角色不允许被授予给角色。
-
-### 4.3 查看授权
-
-支持以被授予身份和被授权对象两个角度来查看授权。
-
-从被授权身份角度查看，例如：show grants to user my\_user; 将显示该用户被授予的所有角色，以及被**直接**授予的权限。
-
-从被授权对象角度查看，例如：show grants on table my\_table; 将显示该对象所有被授出的权限，包含授予用户的和角色的。
-
-### 4.4 授权操作
-
-元数据对象的授权操作，可以使用SQL操作，详见GRANT和REVOKE语句的相关介绍。也可以在“管理”-“安全”-“权限”页面中进行Web端操作。
-
-业务对象的授权目前仅支持通过授予预置角色的方式授予，暂不支持单独对业务对象授权。

-# 管理用户
-
-本文介绍如何在账户中添加更多用户并管理这些用户。
-
-具备账户管理员角色的用户，可以通过管理中心的“用户管理”功能对账户下的用户进行管理操作。您可以通过页面导航进入该功能页面。
-
-## 配置账号管理员
-
-仅具备账户管理员（Account\_admin）角色的用户可以对全局用户进行创建和维护。创建云器账户的第一个用户，默认被授予账户管理员角色。
-
-具备账户管理员（Account\_admin）角色的用户可以配置其他用户成为账户管理员角色。账户管理员角色可授予一名或多名用户，但账户中至少需要有一名用户拥有此角色。为避免因账户管理员用户登录异常而影响业务操作，建议至少配置两名用户担任账户管理员角色。
-
-管理账户管理员角色的操作步骤如下：
-
-1. 登录后，在<您的account\_name>.accounts.clickzetta.com/workbench页面点击“用户管理”，找到需要设置为账户管理员的用户，点击其右侧的“...”按钮展开操作菜单，然后点击“编辑”。
-
-:-: ![](.topwrite/assets/image_1735043871476.png =805)
-
-2. 在弹窗中的“设为账户管理员”一栏中选择“是”，然后点击“保存”。
-
-:-: ![](.topwrite/assets/image_1735043951355.png =365)
-
-3. 账户管理员可以移除其他用户的“账户管理员”角色。操作与授予账户管理员角色类似，在用户的“编辑”弹窗中，将“设为账户管理员”一栏选择为“否”即可。
-
-## 用户管理
-
-### 创建全局用户
-
-具备账户管理员角色的用户在“用户管理”页面点击“新建用户”按钮，填写新用户的用户名、密码和手机号等信息后，即可创建全局用户。
-
-:-: ![](.topwrite/assets/image_1735044006849.png =790)
-
-:-: ![](.topwrite/assets/image_1735045263309.png =426)
-
-### 编辑全局用户信息
-
-在“用户管理”页面，找到需要编辑的用户，点击其右侧的“...”按钮展开操作菜单，然后点击“编辑”按钮，即可编辑用户信息。仅可修改用户的邮箱信息，以及设置该用户是否具有“账户管理员”角色。为保障系统安全，账户管理员不可修改其他用户的密码和手机号信息。
-
-:-: ![](.topwrite/assets/image_1735044079989.png =780)
-
-### 禁用全局用户
-
-禁用全局用户将立即改变该用户的状态，并禁止以该用户身份进行的所有操作。禁用全局用户可用于在识别出安全风险后，紧急停止该用户的所有操作，避免损失扩大。
-
-仅账户管理员角色的用户可以禁用全局用户。在“用户管理”页面，找到需要禁用的用户，点击其右侧的“...”按钮展开操作菜单，然后点击“禁用”按钮，二次确认后即可禁用该用户。
-
-### 启用全局用户
-
-仅“禁用”状态下的用户可被启用。在“用户管理”页面，找到需要启用的用户，点击其右侧的“...”按钮展开操作菜单，然后点击“启用”按钮即可启用该用户。
-
-### 删除全局用户
-
-在“用户管理”页面，找到需要删除的用户，点击其右侧的“...”按钮展开操作菜单，然后点击“删除”按钮。在弹窗中输入该用户的用户名以确认删除。删除用户并不会主动使该用户的登录会话失效或断开以此用户身份建立的JDBC连接。但当此用户在Web端进行任意操作，或使用JDBC连接执行任意请求时，会返回身份失效信息。
-
-### 修改用户密码
-
-账户管理员不可代其他用户修改其密码，仅当前登录用户可修改自己的密码。用户登录状态下，点击左下角的用户名，然后点击“修改密码”。在弹窗中完成验证码验证后，输入新密码即可完成密码修改。修改后的密码在下次登录时生效，不影响当前登录状态。
-
-### 修改用户手机号
-
-账户管理员不可代其他用户修改其手机号，仅当前登录用户可修改自己的手机号。用户登录状态下，点击左下角的用户名，然后点击“用户信息”按钮，打开用户信息弹窗。在手机号右侧点击“编辑”按钮，在弹窗中依次验证当前手机号并输入新手机号，即可完成手机号修改。
-
-^
-
-## 服务用户管理
-
-### 创建自定义服务用户
-
-具备账户管理员角色的用户在“用户管理”页面点击“新建自定义服务用户”按钮，填写服务用户的用户名和密码即可新建自定义服务用户。
-
-:-: ![](.topwrite/assets/image_1735045434327.png =475)
-
-^
-
-### 修改服务用户密码
-
-具备“账户管理员”角色的用户可以修改服务用户的密码。由于修改自定义服务用户密码属于敏感操作，需要验证**当前登录用户**的手机号，正确输入短信验证码后方可修改。
-
-:-: ![](.topwrite/assets/image_1735045692635.png =472)
-
-^
-
-### 禁用服务用户
-
-禁用服务用户将立即改变该服务用户的状态，并禁止使用该服务用户身份进行的所有操作。
-
-仅具备账户管理员角色的用户可以禁用服务用户。在“用户管理”页面，找到需要禁用的服务用户，点击其右侧的“...”按钮展开操作菜单，然后点击“禁用”按钮，二次确认后即可禁用该服务用户。
-
-:-: ![](.topwrite/assets/image_1735045875934.png =810)
-
-### 删除服务用户
-
-在“用户管理”页面，找到需要删除的服务用户，点击其右侧的“...”按钮展开操作菜单，然后点击“删除”按钮。在弹窗中输入该服务用户的用户名以确认删除。
-
-由于服务用户身份通常被关联在系统调度任务或其他应用任务中，删除正在使用的服务用户可能导致生产任务中断或造成故障，因此删除服务用户的弹窗提供了是否“强制删除”的勾选框：
-
-:-: ![](.topwrite/assets/image_1735046163259.png =627)
-
-* 如不勾选“强制删除”，则该服务用户身份将被“软删除”，所有使用该服务用户身份进行的任务将中断。但该服务用户仍将保留24小时。在此期间，可点击“恢复”按钮将其状态恢复为“正常”。恢复后，使用该服务用户的任务可重新正常执行（若任务因无重试机制或超过重试次数而失败，可能需要手动启动）。24小时后，该服务用户身份将被永久删除，不可恢复。
-
-:-: ![](.topwrite/assets/image_1735046443500.png =799)
-
-* 如勾选“强制删除”，则不提供保留期，直接删除该服务用户身份。

-# 监控告警
-
-## 简介
-
-监控告警系统为您提供了强大的监控任务运行状态和异常情况的功能。通过使用系统内置的规则或创建自定义规则，您可以实时监控任务运行状态，并在发生异常时接收告警信息。本指南将帮助您了解监控告警系统的核心概念、功能和操作步骤。
-
-## 核心概念
-
-1. **系统消息**：系统内部产生的全量消息，包含产品、模块、对象和消息内容等关键属性。系统消息是监控规则和告警事件的基础。
-2. **监控规则**：用户定义的一组配置信息，用于筛选关注的关键系统消息。监控规则帮助您确定哪些消息需要关注。
-3. **告警事件**：基于监控规则筛选出的系统消息。告警事件将显示在产品界面上，供用户查看和处理。
-4. **告警消息推送**：在告警事件发生后，根据配置的通知策略（如电话、短信等），将告警通知发送给相应的接收人。
-
-## 告警事件列表
-
-在告警事件列表中，您可以查看当前实例下所有触发监控规则的告警信息。针对列表中的告警事件，您可以执行以下操作：
-
-- **抑制**：设置当前告警事件在指定时间内不再发送消息。
-- **关闭**：关闭当前告警事件，停止接收此类消息。
-

-**配置Bucket基本信息**
-
-| 配置项          | 设置值                           | 说明                                                                |
-| ------------ | ----------------------------- | ----------------------------------------------------------------- |
-| **Bucket 名称** | 自定义（如：`my-company-lakehouse`） | 全局唯一，建议包含用途标识                                                     |
-| **地域**       | 与 Lakehouse 实例相同                | ⚠️ **关键要求**：必须选择与 ClickZetta Lakehouse 实例相同的地域                      |
-| **存储类型**     | 标准存储                          | 避免使用低频或归档存储，频繁读取会产生超额取回费用。                                         |
-| **存储冗余类型**   | 本地冗余存储（LRS）                   | 可根据需求选择同城冗余存储（ZRS）。                                                 |
-| **读写权限**     | 私有                            | 确保数据安全。                                                           |
-| **服务端加密**    | 无                             | Lakehouse 会自行管理加密，全局加密可能影响性能。                                      |
-| **版本控制**     | 关闭                            | 避免产生额外费用。                                                          |
-| **定时备份**     | 关闭                            | 对象存储内的备份由于缺少元数据，单独备份出的数据不可读。如需备份，可使用 Lakehouse 的 Time Travel 功能进行备份。 |
-
-***
-
-### 使用已有存储桶
-
-如果您选择使用已有的存储桶：
-
-#### 验证地域配置
-
-存储桶必须与 ClickZetta Lakehouse 实例在同一地域（Region）。例如：
-- Lakehouse 实例在：阿里云华东 2（上海）
-- OSS Bucket 必须在：华东 2（上海）
-
-您的服务实例所在“云服务商和地域”信息可在服务实例首页查询到：
-
-:-: ![](/.topwrite/assets/image_1760270239517.png =747)
-
-#### 选择存储路径
-
-您可以选择以下方式之一：
-
-**方式一：使用整个 Bucket（推荐）**
-
-适用场景：Bucket 专用于 Lakehouse
-
-**方式二：使用 Bucket 下的特定目录**
-
-适用场景：需要在同一 Bucket 中隔离不同用途的数据
-
-***
-
-**数据安全警告**：
-
-1.  请确保所选路径不与其他业务系统共用。
-2.  ClickZetta Lakehouse 会对该路径下的文件进行读、写、删除操作。
-3.  共用路径可能导致：
-    *   数据被意外删除或覆盖。
-    *   影响其他业务系统的正常运行。
-    *   数据一致性问题。
-
-建议：为 Lakehouse 创建独立的 Bucket 或使用独立的目录。
-
-### 记录必要信息
-
-请记录以下信息，后续配置时需要使用：
-
-* **Bucket名称**
-* **Bucket所在地域**
-* **存储路径**（如使用子目录）
-* **您的阿里云主账号ID**
-
-查看主账号ID的方法：
-
-1. 登录阿里云控制台
-2. 点击右上角头像
-3. 在"账号信息"中查看"账号ID"
-
-## 步骤二：配置Bucket访问策略
-
-**1. 进入 Bucket 管理页面**
-
-*   在 OSS 控制台找到您的 Bucket
-*   点击 Bucket 名称进入详情页
-
-**2. 进入权限控制页面**
-
-:-: ![](/.topwrite/assets/image_1760270528220.png =752)
-
-* 点击左侧菜单“权限控制” → “Bucket 授权策略”。
-* 点击“添加授权”。
-
-**3. 配置授权策略**
-
-选择“自定义授权”，填写以下信息：
-
-| 配置项      | 设置值                                                                           |
-| -------- | ----------------------------------------------------------------------------- |
-| **授权资源** | `acs:oss:*:*:your-bucket-name/*` 或 `acs:oss:*:*:your-bucket-name/your-path/*` |
-| **授权用户** | 填写 ClickZetta Lakehouse 的主账号 ID：1384322691904283                                 |
-| **授权操作** | 选择“完全控制”。                                                                     |
-| **条件**   | 不设置。                                                                           |
-
-:-: ![](/.topwrite/assets/image_1760270723389.png =588)
-
-^
-
-**为什么需要完全控制权限？**
-
-ClickZetta Lakehouse 需要该路径下的完全控制权限，以确保能正常进行数据的增、删、读、写操作。
-
-^
-
-完成上述配置后，即可在创建私有存储时使用您的私有存储路径和云平台主账号ID。

-# 创建阿里云存储连接
-
-本步骤的目标是：允许 Lakehouse 集群访问阿里云上的对象存储 OSS。为了完成这个目标，可以使用阿里云提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
-
-## 方式1：访问密钥（AK信息）
-
-仅需提供拥有访问 OSS 权限的账号的 AccessKey ID 和 AccessKey Secret 信息，利用这些信息创建存储连接（Storage Connection）对象，示例如下：
-
-```
-CREATE STORAGE CONNECTION IF NOT EXISTS hz_conn_ak
-    TYPE oss
-    ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com'
-    ACCESS_ID = 'LTAI5tMmbq1Ty1xxxxxxxxx'
-    ACCESS_KEY = '0d7Ap1VBuFTzNg7gxxxxxxxxxxxx'
-    COMMENTS = 'OSS public endpoint';
-```
-
-## 方式2：角色授权（RoleARN）
-
-需要创建一个角色和权限策略：权限策略代表 OSS 服务的访问策略，将这个策略授权给创建的角色。
-
-**以下主要讲述角色授权方式（RoleARN）的具体操作步骤：**
-
-### 1. 阿里云侧操作：在阿里云 RAM 控制台中创建权限策略（CzUdfOssAccess）
-
-> 注意：需要用户具备 RAM 权限。
-
-* 访问阿里云访问控制（RAM）控制台。
-* 左侧导航栏 **权限管理** -> **权限策略**，在权限策略界面选择 **创建权限策略**。
-* 在**创建权限策略**页面选择 **脚本编辑** 页签，将下面 `[bucket_name_1|2|3]` 替换为实际的 OSS bucket 名称。注意：按照阿里云 OSS 的约定，同一个 bucket 需要有两条 Resource 条目：`"acs:oss:*:*:bucket_name_1"` 与 `"acs:oss:*:*:bucket_name_1/*"` 同时存在才能达到授权效果。
-
-```JSON
-{
-    "Version": "1",
-    "Statement": [
-        {
-            "Effect": "Allow",
-            "Action": [
-                "oss:GetObject",
-                "oss:ListObjects",
-                "oss:PutObject",
-                "oss:DeleteObject"
-            ],
-            "Resource": [
-                "acs:oss:*:*:bucket_name_1",
-                "acs:oss:*:*:bucket_name_1/*",
-                "acs:oss:*:*:bucket_name_2",
-                "acs:oss:*:*:bucket_name_2/*",
-                "acs:oss:*:*:bucket_name_3",
-                "acs:oss:*:*:bucket_name_3/*"
-            ]
-        }
-    ]
-}
-```
-
-![](.topwrite/assets/OSS_P.jpeg)
-
-^
-
-### 2. 阿里云侧：在阿里云 RAM 中创建角色 CzUDFRole
-
-* 在阿里云访问控制（RAM）控制台左侧导航栏，进入 **身份管理** -> **角色**，创建角色。
-* 在 **创建角色** 页面中，选择类型为 **阿里云账号**，在 **配置角色** 中填写自定义角色名称（如 CzUDFRole），在 **选择信任的云账号** 中选择 **其他云账号**，并填入账号 ID：1384322691904283，点击 **完成**。
-
-```Properties
-{
-    "Version": "1",
-    "Statement": [
-        {
-            "Action": "fc:*",
-            "Resource": "*",
-            "Effect": "Allow"
-        },
-        {
-            "Action": "ram:PassRole",
-            "Resource": "*",
-            "Effect": "Allow",
-            "Condition": {
-                "StringEquals": {
-                    "acs:Service": "fc.aliyuncs.com"
-                }
-            }
-        }
-    ]
-}
-```
-
-* 创建完成后，点击 **为角色授权**：在 **自定义策略** 中，将刚创建的策略（CzUdfOssAccess）授权给该角色。在角色 CzUDFRole 详情页中，获取该角色的 RoleARN 信息：`'acs:ram::1222808864xxxxxxx:role/czudfrole'`
-
-![](.topwrite/assets/20231113-153016.jpeg)
-
-^
-
-### 3. Lakehouse 侧：创建 Connection
-
-* 在 Studio 或者 Lakehouse JDBC 客户端中执行以下命令：
-
-```SQL
-CREATE STORAGE CONNECTION hz_oss_conn_rolearn 
-    TYPE oss 
-    REGION = 'cn-hangzhou' 
-    ROLE_ARN = 'acs:ram::1222808864467016:role/czudfrole' 
-    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com';
-```
-
-* 执行 `DESC CONNECTION` 获取 `external_id` 信息。本示例中，`external_id` 为 `O0lQUogDJajHqnAQ`。
-
-![](.topwrite/assets/bloygC9Z6Q.jpg)
-
-### 4. 阿里云侧：在阿里云 RAM -> 角色 -> 信任策略中，修改 CzUDFRole 的 **信任策略**
-
-```Python
-{
-  "Statement": [
-    {
-      "Action": "sts:AssumeRole",
-      "Condition": {
-        "StringEquals": {
-          "sts:ExternalId": "O0lQUogDJajHqnAQ"
-        }
-      },
-      "Effect": "Allow",
-      "Principal": {
-        "RAM": [
-          "acs:ram::1384322691904283:root"
-        ]
-      }
-    }
-  ],
-  "Version": "1"
-}
-```
-
-创建完成后，即可在创建外部 Volume 的语句中，使用该 Storage Connection 对象挂载对象存储的路径。

-# 修改dynamic table
-
-Lakehouse 系统支持使用 `ALTER` 语句对动态表进行运维管理：
-
-* **暂停和启动调度任务**：控制由 Lakehouse 系统自动刷新的调度任务。
-* **表注释**：更新动态表的描述信息。
-* **列名**：修改现有列的名称。
-
-对于涉及 **SQL 查询逻辑变化** 的修改（即动态表定义中的 `SELECT` 加工过程），必须使用 `CREATE OR REPLACE` 语法。这是因为动态表与普通表不同，其定义包含了数据加工逻辑，而不仅仅是静态结构。以下需要使用CREATE OR REPLACE 语法修改。需要注意的是，如果用户不是简单的删除列/添加列（添加列定义：只能是从表一路经由 SELECT 透传的，不能参与任何会影响其他列的计算，例如 join key、group key 等），则在 CREATE OR REPLACE 发生后，REFRESH 任务会退化为一次全量刷新。
-
-* **调度周期**：调整调度任务的执行频率。
-* **计算集群**：指定用于处理动态表的计算资源。
-* **增加列**：动态表增加列，涉及到SQL语法结构变化。
-* **减列**：动态表减列，涉及到SQL语法结构变化。
-* **修改列类型**：涉及到SQL语法结构变化。
-* **修改动态表中SQL语法定义**：涉及到SQL语法结构变化。
-
-# 语法
-
-## 暂停Lakehouse系统刷新的调度任务
-
-```
--- 暂停Lakehouse系统刷新的调度任务
-ALTER DYNAMIC TABLE dt_name SUSPEND;
-```
-
-## 启动Lakehouse系统刷新的调度任务
-
-```
--- 启动Lakehouse系统刷新的调度任务
-ALTER DYNAMIC TABLE dt_name RESUME;
-```
-
-## 修改表的注释（COMMENT）
-
-```SQL
--- 修改表的comment
-ALTER DYNAMIC TABLE dt_name SET COMMENT 'comment';
-```
-
-## 修改动态表中列的名称
-
-```
-ALTER DYNAMIC TABLE dt_name RENAME COLUMN column_name TO new_column_name;
-```
-
-示例
-
-```
-ALTER DYNAMIC TABLE change_table  RENAME COLUMN i TO ii;
-```
-
-## 修改动态表中列的注释（COMMENT）
-
-```
-ALTER DYNAMIC TABLE table_name CHANGE COLUMN column_name_identifier COMMENT 'comment'
-```
-
-案例
-
-```
-ALTER DYNAMIC TABLE change_table  CHANGE COLUMN ii COMMENT 'comment';
-```
-
-## 修改表的属性（PROPERTIES）
-
-功能：通过 ALTER DYNAMIC TABLE 命令，您可以为动态表设置或修改属性。目前为保留参数。
-
-语法：
-
-```
---为动态表设置或修改属性
-ALTER DYNAMIC TABLE dt_name SET PROPERTIES("key"="value");
---删除属性
-ALTER DYNAMIC TABLE dt_name SET PROPERTIES("key");
-```
-案例
-```
---增加属性
-ALTER DYNAMIC TABLE dt_name set properties('aa'='bb');
---修改属性
-ALTER DYNAMIC TABLE dt_name set properties('aa'='cc');
---删除属性
-ALTER DYNAMIC TABLE dt_name unset properties('aa');
-
-```
-
-## 修改调度周期
-
-使用 CREATE OR REPLACE 语法，示例如下
-
-```
---原表
-CREATE dynamic TABLE dt_name
-REFRESH   interval 10 MINUTE vcluster DEFAULT AS
-SELECT    *
-FROM      student02;
-
---修改后
-CREATE OR  REPLACE dynamic TABLE dt_name
-REFRESH   interval 20 MINUTE vcluster DEFAULT AS
-SELECT    *
-FROM      student02;
-```
-
-## 修改计算集群
-
-使用 CREATE OR REPLACE 语法，示例如下
-
-```
---原表
-CREATE dynamic TABLE dt_name
-REFRESH   interval 10 MINUTE vcluster DEFAULT AS
-SELECT    *
-FROM      student02;
-
---修改后
-CREATE OR   REPLACE dynamic TABLE dt_name
-REFRESH   interval 10 MINUTE vcluster alter_vc AS
-SELECT    *
-FROM      student02;
-```
-
-## 增加列

-| j           | int       |         |
-+-------------+-----------+---------+
-
-```
-
-## 使用示例
-
-1. 暂停名为 "dynamic_sales" 的动态表的调度任务：
-
-```SQL
-ALTER DYNAMIC TABLE dynamic_sales SUSPEND;
-```
-
-2. 启动名为 "dynamic_inventory" 的动态表的调度任务：
-
-```SQL
-ALTER DYNAMIC TABLE dynamic_inventory RESUME;
-```
-
-3. 对于设置过 refreshOption 的动态表 dt_name，修改刷新任务使用的计算资源
-
-```SQL
-CREATE dynamic TABLE dt_name
-REFRESH   interval 10 MINUTE vcluster DEFAULT AS
-SELECT    *
-FROM      student02;
-
-CREATE OR  REPLACE dynamic TABLE dt_name
-REFRESH   interval 10 MINUTE vcluster alter_vc AS
-SELECT    *
-FROM      student02;
-```
-
-4. 修改已有的动态表注释（COMMENT）
-
-```
-ALTER DYNAMIC TABLE bulk_order_items_dt SET COMMENT 'comment';
-```

-# 修改物化视图
-支持使用 ALTER 语句对 MATERIALIZED VIEW 进行运维管理，包括暂停和启动由 Lakehouse 系统刷新的调度任务。当创建 MATERIALIZED VIEW 时，使用 refreshOption 语法，可以通过以下语句来控制任务的执行状态。
-
-有关更多详细信息，请参阅[物化视图](<MATERIALIZEDVIEW.md>)。
-
-## 功能说明
-Lakehouse 系统支持使用 `ALTER` 语句对物化视图进行运维管理：
-* **暂停和启动调度任务**：控制由 Lakehouse 系统自动刷新的调度任务。
-* **表注释**：更新物化视图的描述信息。
-* **列名**：修改现有列的名称。
-
-对于涉及 **SQL 查询逻辑变化** 的修改（即物化视图定义中的 `SELECT` 加工过程），必须使用 `CREATE OR REPLACE` 语法。这是因为动态表与普通表不同，其定义包含了数据加工逻辑，而不仅仅是静态结构。以下修改需要使用 CREATE OR REPLACE 语法：
-* **调度周期**：调整调度任务的执行频率。
-* **计算集群**：指定用于处理物化视图的计算资源。
-* **增加列**：物化视图增加列，涉及到SQL语法结构变化。
-* **减列**：物化视图删除列，涉及 SQL 语法结构变化。
-* **修改列类型**：涉及 SQL 语法结构变化。
-* **修改物化视图中 SQL 语法定义**：涉及 SQL 语法结构变化。

-# 修改分享对象（SHARE）
-
-## 功能描述
-
-该语句用于修改分享对象（SHARE）。您可以使用此语句为分享对象添加或移除目标服务实例（INSTANCE）。
-
-## 语法
-
-```SQL
-ALTER SHARE <share_name> [ADD | REMOVE] INSTANCE <instance_name>;
-```
-
-## 参数说明
-
-1. **share_name**：需要修改的分享对象名称。
-2. **ADD | REMOVE**：对分享对象的操作，ADD 表示添加分享目标服务实例，REMOVE 表示移除已分享的服务实例。
-3. **instance_name**：服务实例的名称，需确保全局唯一。服务消费端用户可以在首页右侧或在服务实例的 URL 中找到自己的服务实例名称，并提供给分享者进行配置。
-
-## 使用示例
-
-**添加分享目标服务实例**
-
-假设您创建了一个名称为`SHARE_DEMO`的分享对象，其 `kind` 属性为 ‘OUTBOUND’，想要将其分享给名为`instancedemo`的服务实例，可以使用以下语句：
-
-```SQL
-ALTER SHARE SHARE_DEMO ADD INSTANCE instancedemo;
-```
-
-**移除分享目标服务实例**
-
-如果您创建了一个名称为`SHARE_DEMO`的分享对象，并且已分享给名为 `instancedemo` 的服务实例，想要收回对该服务实例的分享，可以使用以下语句：
-
-```SQL
-ALTER SHARE SHARE_DEMO REMOVE INSTANCE instancedemo;
-```
-
-## 注意事项
-
-* 确保在执行此操作时，已登录到具有相应权限的账户。
-* 在添加或移除分享目标服务实例时，请确保输入的实例名称正确无误。
-* 对 SHARE 对象执行 REMOVE INSTANCE 后，目标服务实例会立即失去使用该分享数据的权限。请谨慎操作，确认操作影响。
-
-通过以上步骤，您可以轻松地管理分享对象及其关联的服务实例。

-# 修改工作空间属性
-
-在本节中，我们将介绍如何修改工作空间的属性，包括修改工作空间的注释（comment）等。这将帮助您更好地管理和组织您的工作空间。
-
-## 修改工作空间的注释
-
-要修改工作空间的注释，您可以使用以下SQL语句：
-
-```
-ALTER WORKSPACE wbname SET COMMENT 'comment';
-```
-
-在这里，`wbname`代表您要修改的工作空间名称，而`comment`则是您想要设置的新注释。
-
-## 修改Workspace的PROPERTIES
-
-```SQL
-ALTER WORKSPACE wbname SET PROPERTIES ('key'='value')
-```
-
-要查看 Workspace PROPERTIES，请使用以下语法：
-
-```SQL
-SHOW PROPERTIES IN WORKSPACE <workspace_name>
-```
-
-## 案例
-
-**示例：修改工作空间的注释**
-
-假设您有一个名为`ql_ws`的工作空间，您想要为其添加一条注释：“这是一个用于查询的工作环境。”您可以使用以下SQL语句进行修改：
-
-```
-ALTER WORKSPACE ql_ws SET COMMENT '这是一个用于查询的工作环境。';
-```
-
-执行该语句后，您可以使用 `DESC` 命令查看工作空间的详细信息，确认注释已成功修改：
-
-```
-DESC WORKSPACE ql_ws;
-```
-
-查询结果将显示类似以下内容：
-
-```
-+--------------------+-----------------------------------------+

-# 合理规划和使用Virtual Cluster
-
-本章节将介绍ClickZetta Lakehouse弹性计算资源的产品特性及规划使用的方法。
-
-## Virtual Cluster特性介绍
-
-计算集群（Virtual Cluster，简称：VC）是ClickZetta Lakehouse提供的计算资源集群服务。计算集群提供在Lakehouse中执行查询分析所需的CPU、内存、本地临时存储（SSD介质）等资源。这三种资源被捆绑到称为Lakehouse计算单元的计算规模单元中。 CRU 作为计算资源大小和性能的抽象、规范化的度量单位。
-
-![](.topwrite/assets/image_1718616076626.png)
-
-ClickZetta Lakehouse根据不同规格计算资源的实际使用时长（秒粒度计算时长）进行计量，不同规格的CUR以及计量单价如下：
-
-| **Lakehouse Virtual Cluster规格** | **CRU**\*时 | **MAX\_CONCURRENCY默认值** |
-| ------------------------------- | ---------- | ----------------------- |

-ClickZetta Lakehouse支持纵向和横向2个维度的计算资源弹性伸缩：
-
-* 纵向：通过修改Virtual Cluster的规格大小调整CRU数量，提升或降低指定集群的算力和性能
-* 横向：通过修改集群的Replica数量，扩大或减少Cluster副本数调整并发查询能力。
-
-## 根据负载规划计算资源数量和大小
-
-### 计算资源使用最佳实践原则
-
-* 通过多计算资源实现负载隔离
-
-  * 使用多个独立的Virtual Cluster支撑不同业务（Workload）。可根据周期性ETL、线上业务报表、分析师数据分析等不同需求，创建不同的计算资源并分配给不同的用户或应用使用，避免不同业务或人员资源争抢导致的SLA下降。
-
-* 合理设置自动暂停时长
-
-  * Lakehouse的计算资源具备IDLE闲置时自动暂停、作业发起时自动拉起、按实际资源使用时长计费（暂停阶段不计费）的特性，通过AUTO\_SUSPEND\_IN\_SECOND参数可以设置，默认为600秒无查询时自动暂停。
-
-  * 不同场景的建议（考虑数据Cache和资源Resume时间2个维度）
-
-    * 低频使用Ad-hoc查询或ETL作业，AUTO\_SUSPEND\_IN\_SECOND为1Min左右。
-    * 高频分析场景，AUTO\_SUSPEND\_IN\_SECOND=10Min以上，保持分析依赖的数据始终在Cache当中，同时避免频繁VC启停带来的Latency下降。
-
-* 根据负载类型选择Virtual Cluster的资源类型
-
-  * **通用型集群（VCLUSTER\_TYPE=GENERAL**） 可对于分析场景的并发和作业时效性保障要求不强情况下，可以完成分析引擎所做的所有事情。为批处理Workload优化，吞吐优先、支持资源争抢&共享，适用于ELT、数据导入（如外表读取及写入）、Ad-hoc查询等场景。
-  * **分析型集群（VCLUSTER\_TYPE=ANALYTICS**） 支持指定作业并发数的分析引擎。适用于对查询Latency和并发能力有强保障的场景，如Reporting、Dashboard、关键业务的数据产品。
-  * **同步型集群**（**VCLUSTER\_TYPE**=**INTEGRATION**）适用于处理离线集成和实时集成任务。多个集成任务可共用一个同步型计算集群实例。超出集群计算能力的集成任务将进入队列排队。
-
-* 使用弹性并发能力支持关键数据应用
-
-  * 分析型Virtual Cluster支持多Replica副本特性，Replica默认为1，可以在创建时或创建后修改。每个Replica支撑特定的并询并发（由MAX\_CONCURRENCY参数决定，默认为8），每个Virtual Cluster能够支持的并发数量为：Replica Number \* MAX\_CONCURRENCY
-  * \:-:
-    ![](.topwrite/assets/image_1741750995792.png =645)
-  * 并发设置：在确定Virtual Cluster规格大小的情况，提高并发度会可能降低单个Query的查询性能；大多数情况下，并发度上限建议不超过100；并发度的取值建议使用8的整数倍。示例如下：
-
-    ```SQL
-    --创建分析型VC，开启弹性并发(min_replicas=1 max_replicas=3 )
-    create vcluster if not exists your_ap_vc vcluster_size='XSMALL' vcluster_type='Analytics'  AUTO_RESUME=TRUE AUTO_SUSPEND_IN_SECOND=300 min_replicas=1 max_replicas=3 ;
-    —修改replicas参数，提高横向伸缩的Replica数量以增加弹性并发
-    alter vcluster your_ap_vc set max_replicas=6;
-    --修改单个replica的并发大小，适合计算逻辑简单和数据规模较小的固定报表场景
-    alter vcluster your_ap_vc set MAX_CONCURRENCY=32 ;
-    --修改Virtual Cluster的规格大小，影响所有弹性并发创建的replica的规格并发大，以提升单个查询的查询性能
-    alter vcluster your_ap_vc set vcluster_type='MEDIUM';
-
-    3. 查询和配置MAX_CONCURRENCY
-    - 查询MAX_CONCURRENCY
-    使用以下语句，可以查询指定VC的配置参数，可在其中找到该VC集群当前的MAX_CONCURRENCY配置值：
-    DESC VCluster <name>
-    - 配置MAX_CONCURRENCY
-    使用以下语句，可以配置指定VC的MAX_CONCURRENCY。对于分析型的VC集群，MAX_CONCURRENCY的配置适用于其中的所有实例。
-    ALTER VCluster <name> SET MAX_CONCURRENCY = {希望设置的正整数}
-    ```

-## 依据并发需求配置虚拟计算资源实践
-
-云器Lakehouse分析型虚拟计算集群（Virtual Cluster）适用于Ad-hoc、多并发固定报表、实时分析等对于查询时延有较高要求的场景。分析型虚拟计算集群提供以下配置选项：
-
-| **配置选项** | **说明**                                                                                           |
-| -------- | ------------------------------------------------------------------------------------------------ |
-| 规格       | 虚拟集群内计算资源实例大小。规格范围从XS\~5XLarge，规格增加一级，算力资源增加一倍。                                                  |
-| 类型       | 通用型或分析型，此处我们使用分析型。                                                                               |
-| 最大并发数    | 单个计算资源实例支持的并发查询，超过单实例最大并发数时，新的查询将排队或分配到虚拟集群内的其他计算资源实例。                                           |
-| 实例最小值    | 虚拟集群初始启动时集群实例数量，默认为1。                                                                            |
-| 实例最大值    | 虚拟集群可以使用的最大实例数量。当实例最大值>实例最小值时，意味着根据虚拟集群接收到的并发数量是否超过所有计算实例的总最大并发数决定是否自动横向扩展新的计算实例，直到当前实例数量=实例最大值。 |
-| 当前实例数量   | 虚拟集群当前使用的实例数量。                                                                                   |
-
-下图描述了分析型虚拟集群相关参数间的关系：
-
-![](.topwrite/assets/image_1718616481037.png)
-
-垂直伸缩：其中实例规格是对虚拟集群进行垂直伸缩的选项，调整实例规格可以让单个作业获得更大的算力以提升作业性能。
-
-横向伸缩：以提高集群并发能力为目标的弹性能力。分析型集群面向横向伸缩场景，提供了单集群内多实例的架构设计。每个分析型集群通过设置实例最小值、实例最大值定义集群初始实例数量以及横向扩容的上限。
-
-在实际的业务场景中，对于面向用户的数据产品往往有SLA的要求，如100并发下P99的查询延迟小于2秒。同时，也希望计算资源得到充分的利用，在满足业务需求的前提下尽可能降低资源成本。如下图所示：
-
-![](.topwrite/assets/image_1718616492933.png)
-
-在特定的业务场景下，我们希望能够找到性能满足SLA要求的最小资源需求。本文从实践角度，结合示例场景通过以下几个步骤工作来确定合理的资源规格配置。
-
-### 场景示例
-
-数据平台加工后的数据包装称为数据产品（如Dashboard），对外支撑最大20用户并发查询，其中单个用户每次数据产品请求平均产生8个数据平台查询（平均每个Dashboard 8个指标），相当于对数据平台有160个并发查询。要求P99查询延迟小于1.5秒。
-
-数据查询具备以下特点：
-
-* Dashboard查询使用数据集大小：1GB左右。
-* Dashboard查询的特点：以点查、过滤、聚合为主，无JOIN。
-
-本文使用SSB FLAG 1G的数据集和查询语句来模拟上述场景，用于验证并发查询下的集群配置及效果。
-
-### 第1步：找到性能、成本平衡的单实例规格大小
-
-1. 使用不同SIZE的集群规格运行查询（如本文使用从Large->XSMALL几种规格分别进行了测试），找到资源规格尽可能小、同时性能下降不明显的资源规格。
-
-根据下图所示，SSBF-1G的benchmark在XSMALL规格时仍然保持了Large的80%以上性能表现。这里选择XSMALL规格来支持数据产品。
-
-注：根据测试结果，建议 100G数据规模默认使用 Large大小，10G 使用 Medium，1G 对应 Small或XSmall。
-
-![](.topwrite/assets/image_1718616512495.png)
-
-### 第2步：测试单实例下在多大并发下，有较好的查询SLA、QPS
-
-如下图所示，使用XSMALL规格集群，在8并发请求下，QPS较高、P95/P99查询表现好。
-
-![](.topwrite/assets/image_1718616524873.png)
-
-### 第3步：通过横向扩容，找到同时满足SLA和业务实际并发需求的最大实例数
-
-根据前文介绍，一个集群能够支持的并发数= 实例最大值 \* 实例最大并发数。原则上，单实例规格大小确定后，横向扩展的实例具备同样的查询SLA和QPS。
-
-结合测试数据，本文将使用XSMALL规格，最大实例数=10的虚拟集群，可以满足160并发的查询需要。查询响应时长P95=1111毫秒，P99=1280.65毫秒。

-
-### 小结
-
-本节以小规模数据集上的多并发简单查询场景为例，介绍了如何合理设置云器Lakehouse的虚拟计算集群规格大小及相关参数以满足SLA需求。
-
-为简化这个参考过程，以下根据测试信息给出一些经验值供参考。

-
-#### 通过**Web-UI监控**
-
-![](.topwrite/assets/image_1718616681911.png)
-
-增加过滤条件：如通过TAG方式过滤特定作业/作业组
-
-```SQL
---Session级别设置query_tag
-set query_tag='aa';
-select 1;
-```
-
-![](.topwrite/assets/image_1718616691133.png)
-
-#### 通过SHOW JOBS命令**监控近期执行作业成功/排队/超长运行状态**
-
-SHOW JOBS命令获取工作空间内计算资源内正在进行中、已经完成的近期作业。
-
-```SQL
-SHOW  JOBS  [IN VCLUSTER vc_name] [WHERE where_condition ] [LIMIT num];

-# 功能
-
-ANALYZE TABLE 语句用于收集指定 schema 中特定表或所有表的统计信息。统计信息包括表的大小、行数等，查询优化器利用这些信息生成最佳的查询计划。虽然这些统计信息可能会随着数据的变化而过时，但查询优化器仍然可以利用这些过时的信息生成有效的查询计划。在 Lakehouse 中，通过执行 DESC 命令获取的统计信息可能存在延迟，因此执行 ANALYZE TABLE 语句可以获取最新的统计信息。
-
-# 语法
-
-```SQL
--- 收集指定表的统计信息
-ANALYZE TABLE table_name
-   COMPUTE STATISTICS [NOSCAN | FOR COLUMNS col1 , col2... | FOR ALL COLUMNS ]
-
--- 收集指定schema下所有表的统计信息
-ANALYZE TABLES [IN schema_name] COMPUTE STATISTICS [NOSCAN]
-```
-
-# 参数
-
-必选参数：
-
-* `table_name`：要收集统计信息的表名称。支持普通表、动态表、物化视图。
-
-可选参数：
-
-* `NOSCAN`：仅收集表的大小（以字节为单位），不需要扫描整个表。
-* `FOR COLUMNS col1, col2, ...`：收集每个指定列的列统计信息。
-* `FOR ALL COLUMNS`：收集所有列的统计信息。
-* `IN schema_name`：指定目标 schema 的名称。如果不指定，则默认使用当前 schema。
-
-# 注意事项
-
-* 在执行 ANALYZE TABLE 语句时，可能会对表进行扫描，因此可能会影响查询性能。建议在系统负载较低时执行此操作。
-* 在使用 [实时接口](<java_reference/realtime-upload.md>) 追加模式时，ANALYZE TABLE 语句不会统计未提交的数据，因此 `select count(*) from table` 的结果可能偏少。
-
-# 使用示例
-
-1. 收集指定表的统计信息（不扫描表），仅收集表的大小（以字节为单位）：
-
-```SQL
-ANALYZE TABLE sales COMPUTE STATISTICS NOSCAN;
-```
-
-2. 收集指定表的列统计信息：
-
-```SQL
-ANALYZE TABLE customers COMPUTE STATISTICS FOR COLUMNS customer_id, customer_name;
-```
-
-3. 收集指定schema下所有表的统计信息：
-
-```SQL
-ANALYZE TABLES IN sales_schema COMPUTE STATISTICS;
-```
-
-4. 收集指定表的所有列的统计信息：
-
-```SQL
-ANALYZE TABLE orders COMPUTE STATISTICS FOR ALL COLUMNS;
-```

-# 实名认证
-
-实名认证是通过验证您的真实身份信息，以确认您创建的云器账号归属的过程。分为个人认证和企业认证两种类型。
-
-| 类型   | 个人实名认证     | 企业实名认证                  |
-| ------ | ------------ | ------------------------- |
-| 适用对象 | 个人         | 企业、个体工商户、政府、事业单位、学校、组织等 |
-| 账号归属 | 个人         | 企业                      |
-| 认证方式 | 个人身份证+人脸识别 | 企业证件+法人人脸识别             |
-| 认证耗时 | 10分钟       | 10分钟                    |
-
-## 功能权限
-
-对于有多用户的账户，实名认证仅能由拥有账户管理员权限的用户完成。创建该账户的第一个用户会被默认授予账户管理员角色。非管理员用户可查看认证状态，但无法操作认证。
-
-## 如何查看认证状态？
-
-登录云器平台，进入账户主页即可查看当前实名认证状态，如下：

-### 推荐原因
-
-推荐的列可以用作表的 sort key。
-
-挑选的是经常出现在过滤语句中的列。如果将这些列设置为表的 sort key，可以加快 query 的执行速度。
-
-### 如何启用
-
-* 可以在 workspace 上设置 property，系统会分析 workspace 下所有的表。
-
-```Plain
-ALTER WORKSPACE workspace_name SET properties (auto_index='day[,150,5,100]');
-
-比如：
-ALTER WORKSPACE quick_start SET properties (auto_index='day'); 
-ALTER WORKSPACE quick_start SET properties (auto_index='day,150,5,100');
-
-第一个参数为必须设置，即指定是每天收集还是每月收集，每月收集为每月1号收集，收集时间为晚上6点
-第二个参数为使用最近多长时间的job（单位是分钟），默认为150
-第三个参数为job需要重复多少次才会被使用，默认为5
-第四个参数为每个列使用的最多的job数，默认为100
-```
-
-* 自动收集
-
-系统会自动收集每个 schema 中过滤语句使用最多的 10 张表。
-
-### 如何查询
-
-```Plain
-Select * from information_schema.sortkey_candidates;
-
-返回结果比如:
-instance_id,workspace_id,workspace_name,schema_id,schema_name,table_id,table_name,col,statement,ratio,insert_time,p_date
-11111111111,855911111111,aaaaaaaaaaa,23671111111111,ddddddddd,84465111,aaaaaaaaaaa.ddddddddd.member,brandid,alter table aaaaaaaaaaa.ddddddddd.member set properties("hint.sort.columns"="brandid"), 2.21%,05:49.1,2024/11/7
-11111111111,855911111111,aaaaaaaaaaa,23671111111111,ddddddddd,84465111,aaaaaaaaaa.ddddddddd.member,birthday,alter table aaaaaaaaaa.ddddddddd.member set properties("hint.sort.columns"="birthday"),0.01%,05:49.1,2024/11/7
-11111111111,855911111111,aaaaaaaaaaa,23671111111111,ddddddddd,84465111,aaaaaaaaaaa.ddddddddd.member,id,alter table aaaaaaaaaaa.ddddddddd.member set properties("hint.sort.columns"="id"),0.01%,05:49.1,2024/11/7
-
-可以看到对于aaaaaaaaaaa.ddddddddd.member表来说brandid的提升效果最高，所以设置为sortkey alter table aaaaaaaaaaa.ddddddddd.member set properties("hint.sort.columns"="brandid"),此设置会对
-
-```
-
-包含的列为：`instance_id`、`workspace_id`、`workspace_name`、`schema_id`、`schema_name`、`table_id`、`table_name`、`col`、`statement`、`ratio`、`insert_time`、`p_date`。
-
-其中 `p_date` 为分区列，其格式是 `yyyy-mm-dd`。
-
-`insert_time` 是收集结果插入的时间。
-
-`col` 是推荐的列，当前为单列。
-
-`statement` 是用于将推荐列设置为排序列的 SQL 语句。
-
-`ratio` 为估算的提升效果，为百分比。
-
-### 使用建议
-
-建议使用 [analyze语句](<analyze-table.md>) 对表收集一下 column 的 stats，这会提高推荐的准确性。

-# 创建亚马逊云存储连接
-
-本步骤的目标是：允许 Lakehouse 集群访问亚马逊云(AWS)的对象存储 S3。为了完成这个目标，可以通过AWS 的**身份与访问管理(IAM**) 产品提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
-
-## 基于访问密钥
-
-```
-CREATE STORAGE CONNECTION aws_bj_conn
-    TYPE S3
-    ACCESS_KEY_ID = 'AKIAQNBSBP6EIJE33***'
-    SECRET_ACCESS_KEY = '7kfheDrmq***************************'
-    ENDPOINT = 's3.cn-north-1.amazonaws.com.cn'
-    REGION = 'cn-north-1';
-```
-
-### 参数：
-
-* TYPE：为对象存储类型，AWS 应填写 S3（大小写不限）
-* ACCESS\_KEY\_ID / SECRET\_ACCESS\_KEY：为AWS 的访问密钥，获取方式参考：[访问密钥](https://docs.aws.amazon.com/zh_cn/IAM/latest/UserGuide/id_credentials_access-keys.html)
-* ENDPOINT:  S3 的服务地址，AWS 中国区分为北京区和宁夏区，北京区的S3 的服务地址为 `s3.cn-north-1.amazonaws.com.cn`， 宁夏区 `s3.cn-northwest-1.amazonaws.com.cn`，可参考：[中国区终端节点](https://docs.amazonaws.cn/aws/latest/userguide/endpoints-arns.html) 分别找到北京区域和宁夏区域的终端节点 -> Amazon S3 对应的终端节点
-* REGION：AWS 中国区分为北京区和宁夏区，区域值为：北京区 `cn-north-1`， 宁夏区 `cn-northwest-1`，可参考：[中国区终端节点](https://docs.amazonaws.cn/aws/latest/userguide/endpoints-arns.html)。国际站请参考：[Amazon Simple Storage Service endpoints and quotas](https://docs.aws.amazon.com/general/latest/gr/s3.html)
-
-## 基于角色授权
-
-需要在目标云对象存储 S3 所属的账号，在 IAM 中创建一个**权限策略**和**角色**：权限策略代表访问AWS S3 数据的规则，将这个策略授权给创建的角色。云器 Lakehouse 通过扮演这个角色来实现与 S3 中数据的读写操作。
-
-### STEP1: AWS侧创建权限策略 (LakehouseAccess )：
-
-* 登录AWS 云平台，进入**身份与访问管理(IAM**) 产品控制台

-# 补数任务
-
-补数据功能可通过补充历史或未来一段时间的数据，将数据写入对应时间分区。若代码中配置了调度参数，系统将根据补数据选择的业务时间自动替换为具体值，并结合业务代码将对应时间的数据写入指定分区。具体写入的分区与执行的代码逻辑由任务定义中的代码决定。
-
-## **功能使用场景**
-
-* 当任务新建后，若希望对历史数据进行加工，可通过补数据功能选择历史某个时间段来执行任务；
-* 当任务在某个时间段内数据有问题或者任务本身异常时，可通过补数据功能对历史异常的数据或任务重新生成实例并执行，以达到修复历史数据的目的。
-
-## 功能操作
-
-### 步骤一：新建补数据任务
-
-1. 点击左侧导航**运维监控 -> 任务运维**，选中**周期任务** Tab，并选择其中任意一个已管理的周期任务，点击操作栏中的“补数据”，进入补数据操作界面。
-2. 配置补数任务的相应参数
-
-* 任务名称：系统默认名称，暂不支持用户修改
-
-* 选择补数任务包含的任务节点
-
-  * 包含当前节点：用户可根据实际需求选择是否勾选当前任务参与补数。
-  * 包含下游节点：用户可根据实际需求勾选需要补数据的**下游任务链路**，支持不选择、选择全部、自定义选择范围三种模式。
-
-* 任务定时时间范围：在创建补数据任务时，支持添加多段计划执行时间范围，用于满足补充多段不连续时间的需求。目前最多支持添加4段计划执行时间，且不允许选择重叠的时间段。
-
-* 最大并发数：表示当连续补充多个周期的数据时，若同时运行的实例数达到此并发上限，则可以并行运行多个周期的实例，从而提升补数据的效率，但也会消耗更多的资源。
-
-  * 最大并发数量，指的是同时运行的最大实例个数。
-
-* 补数自依赖：若用户需要补数任务严格按照业务时间依次往后执行，可选择补数自依赖选项。
-
-  * 若用户同时配置了最大并发数和补数自依赖，则整体执行效率可能会下降。
-
-^
-
-最大并发数与补数自依赖对执行效率的影响：
-
-* 配置最大并发数时，若该周期任务本身没有配置自依赖，同时也没有勾选补数自依赖选项，系统会基于用户配置的并发数，按照系统资源、依赖关系等随机分配执行的具体实例。
-* 若周期任务本身配置了自依赖，或勾选了补数自依赖选项，则同时并发的实例数会受到实例自身顺序依赖逻辑的影响，再结合系统资源、依赖关系等随机分配执行的具体实例，效率会降低。
-
-### 步骤二：查看补数据任务
-
-1. 点击左侧导航**运维监控 -> 任务运维**，选中**补数任务** Tab。
-2. 基础信息：包括并发分组、目标任务ID、任务名称、工作空间、是否包含下游、状态、执行顺序、任务定时时间范围、提交时间、提交人等。
-3. 统计图：
-
-* 全局统计信息：可查看当前补数任务内包含的所有计划时间点总数，并按天粒度展示执行状态。
-
-* 按粒度统计图：提供年、月、日三种粒度下的数据统计，点击统计图会联动下方的实例列表。
-
-  * **年视图**：鼠标悬停在日期上方可查看当天的执行情况；
-    ![](.topwrite/assets/image_1723185910796.png)
-  * **月视图**：可在月视图上查看当天要执行的实例总数，鼠标悬停在日历上方可查看执行状态汇总；
-    ![](.topwrite/assets/image_1723185934736.png)
-  * 日视图：支持按天或按小时两种粒度切换，可查看不同聚合粒度下实例的平均耗时时长。
-    ![](.topwrite/assets/image_1723185952493.png)
-
-4. 实例统计列表：默认按照计划时间展示当前补数任务下所有执行实例的信息，点击可跳转到实例执行的详情页面查看依赖关系等详细信息。

-# 离线同步任务
-
-云器 Lakehouse 工作空间的“开发”模块集成了数据同步任务的定义和调度能力。借助数据开发模块的数据同步任务编辑器，可以快速创建数据同步任务。以下对离线同步任务的创建和使用进行说明。
-
-## 新建数据同步任务
-
-您可分别从工作区和开发入口新建同步任务。
-
-* 由工作区新建
-  通过控制台“工作区”入口，在右侧“新建”按钮下选择新建离线同步或实时同步任务。
-
-  ![](.topwrite/assets/image_1690124841165.png =640)
-
-* 由开发入口新建
-  您可进入“开发”页面，在任务区域选择在指定目录下新建同步任务。
-
-  ![](.topwrite/assets/image_1690125196037.png =320)
-
-## 离线同步任务开发
-
-**第一步：新建离线数据同步任务**
-在指定任务保存位置创建指定名称的离线同步任务。
-![](.topwrite/assets/image_1690125712118.png =320)
-系统将生成同步任务，同时在右侧区域打开数据同步任务编辑器供用户编辑。
-![](.topwrite/assets/image_1690125934293.png =640)
-
-**第二步：定义同步任务**
-
-* 选择源和目标数据源及对应数据对象
-  在数据来源侧，选择现有数据源或新建数据源作为数据来源，并指定需要同步的数据对象。在数据目标侧，选择已有数据源或新建数据源作为目标数据源，目标数据的写入对象支持指定已有数据对象，或根据来源对象快速创建。
-  ![](.topwrite/assets/image_1690126242203.png =640)
-  确定来源对象和目标对象后，数据同步任务将生成来源对象与目标对象的字段映射，默认采用同名映射规则，可通过拖动方式调整字段间的映射关系。支持添加常量字段作为源表字段进行映射和写入。
-
-* 设置数据同步任务的容错和并发规则
-  * 任务并发数：可最小设置为1，最大设置为10。
-  * 任务同步速率：可最小设置为1 MB/s，最大不限制。
-    ![](.topwrite/assets/image_1690126859515.png =460)
-
-* 任务的高级配置
-  高级配置区域通常无需配置，保持留空即可。您也可以扩展设定任务的高级参数，例如调整任务使用的内存规格大小。支持的参数如下。具体如何设定，请联系技术支持人员。
-  * jobmanager.memory.process.size
-  * taskmanager.memory.process.size
-    ![](.topwrite/assets/image_1725711386646.png =640)
-
-**第三步：同步任务测试**
-在开发任务界面上点击“运行”，对同步任务进行测试。观察任务执行状态及日志，查询目标表的数据变化，验证同步任务是否正确执行。
-![](.topwrite/assets/image_1690127192272.png =640)
-
-**第四步：设置调度并部署至生产**
-调度配置完成后，可点击任务的“提交”按钮，将其部署至调度系统进行周期性执行。
-![](.topwrite/assets/image_1690127269116.png =640)
-
-在运维中心查看和运维已发布的同步任务。

-## 任务计费
-
-### 问题：数据同步任务如何收费？
-
-回答:数据同步任务的费用，整体分为硬件资源使用费用、数据传输网络费用两大类构成。
-
-* 硬件资源使用费用依据同步型计算集群的规格和使用时长进行按量计费，集群未使用或被停止后，不再收取费用。
-* 数据传输网络费用按实际情况收取：当使用数据集成等功能，批量从Lakehouse通过公网下载、导出数据时，会产生Internet网络传输费用。Internet网络传输以实际产生的传输数据量进行计量并计算费用。从其他数据源通过Internet网络向Lakehouse上传数据所产生的网络传输流量，不收取网络传输费用。若使用专线、Private Link或其他网络产品实现跨云厂商、跨地域或跨VPC网络打通，网络打通本身会产生费用。这部分费用根据网络打通方式的不同，在云器Lakehouse侧产生的由云器收取，在云平台账号中产生的费用由云平台直接收取。
-* 详见：[计费说明](pricing.md)
-
-## 数据源
-
-### 问题：离线同步当前支持的数据源有哪些？
-
-回答:在任务配置页面，进行源端和目标端选择时，会完整列出已支持的数据源类型。若没有可用的数据源，请点击「+」号按钮先前往新建，之后再使用。离线同步的数据源之间可以两两自由组合，来构建丰富的同步链路。详见：[数据源管理](config-datasource.md)
-
-^
-
-### 问题：离线同步如何验证数据源的可访问？
-
-回答:数据源列表中的「测试连通」功能（数据源配置页面也提供该功能），可用于测试数据同步任务环境与数据源之间的访问连通状况。若测试结果显示连通失败，则需检查配置的准确性（如连接串地址、用户名和密码等）以及网络状况。若存在网络不通的问题，可查阅下文的网络连通性章节，其中给出了相应的解决方案。
-
-^
-
-## 网络联通
-
-### 问题：如果数据源端在VPC环境下，如何打通数据同步的网络连通性？
-
-回答:如果数据源在VPC环境下，默认情况下数据同步任务所在的网络环境是无法访问联通的。可以通过以下几种方式来打通：
-
-* 在源端启用允许公网访问、在数据源中配置公网访问的地址。
-* 使用SSH Tunnel：[数据源管理](config-datasource.md)&#x20;
-* 使用Private Link：
-* Private Link和SSH相结合：[通过Private Link和SSH结合来同步VPC内的RDS数据](StudioDI_PrivateLinkVPC_fromRDS.md)
-
-### 问题：如果源端数据库有白名单限制，如何才能确保数据同步任务可连通该数据源？
-
-回答:需将数据同步服务出口IP地址添加至源端的白名单中，不同服务地域的IP地址存在差异，具体地址和配置方式详见：[数据源IP白名单配置指南](datasource_ip_whitelist.md)
-
-## 任务配置
-
-### 问题：离线同步任务配置的主要流程是怎样的？
-
-回答:主要分为数据源创建、来源和目标选择、配置字段映射、并发和脏数据管理等同步规则配置（可选）这几个步骤。配置完成后可手动触发运行测试，随后提交周期定时调度。详见：[离线同步](batch_sync.md)
-
-^
-
-### 问题：如果要控制数据同步时对源端的压力，需要如何配置？
-
-回答:在离线同步任务「同步规则配置」区域，可以通过最大并发数和同步速率两个配置项来分别控制对源端的连接数和读取访问的压力。并发数和同步速率越大、对源端的压力越大。
-
-^
-
-### 问题：如果源端数据中存在“脏数据”的情况，需要如何处理？
-
-回答:在离线同步任务「同步规则配置」区域，可以通过「任务遇脏数据自动结束」和「收集脏数据」两个配置项来控制同步任务对脏数据的处理行为。这些「脏数据」不会被写入到目标端。「脏数据」主要指无法正常写入到目标端的数据，最常见的情况是字段类型不匹配，比如把String类型的字段取值写入到目标INT字段中。
-
-* 「任务遇脏数据自动结束」配置成「是」，那么，在脏数据达到对应的条数时任务会失败退出。
-* 「任务遇脏数据自动结束」配置成「否」，那么，即使有脏数据，任务也会继续执行，不会自动退出。
-* 「收集脏数据」选项会控制是否把脏数据收集起来，在任务运行完成后进行查看。脏数据最多收集1000行数据，最长保存7天。
-
-^
-
-## 报错排查
-
-### 问题：任务运行报错 `java.lang.OutOfMemoryError: Java heap space`如何解决？
-
-原因：通常由于读取的数据中存在较大的字段或行，或者对于支持批量读取数据的数据源，单个批次内同步的数据量较大，超过了同步任务的计算进程的堆内内存。
-
-解决：可通过调整同步任务计算集成内存解决，在任务开发-高级参数中添加参数`taskmanager.memory.process.size`，有效单位m、g，默认1600m
-
-^
-
-### 问题：任务运行报错 `java.lang.OutOfMemoryError: Direct buffer memory`如何解决？
-
-原因：同步任务计算集成的堆外内存不足，通常可能是以下原因：
-
-* 来源数据中中存在较大的字段或行，或者对于支持批量读取数据的数据源，单个批次内同步的数据量较大，且来源数据源会使用堆外内存作为数据缓存，如elasticsearch
-* 目标数据源使用堆外内存攒批发送数据，如Lakehouse，由于一批数据中存在较大行导致某个批次数据超过攒批缓存大小
-
-解决：通常有以下解决方案：
-
-* 参照堆内存超限解决方案，调整`taskmanager.memory.process.size`参数
-* 单独调整任务堆外内存的大小，调整`taskmanager.memory.task.off-heap.size `参数，如256m，或512m
-* 如果数据源支持设置batch size，可适当调小配置值，**但注意，这可能会导致同步效率降低**
-
-### 问题：任务运行报错 `CZLH-67000:Out of Memory undefined: could not allocate block of size 262KB (1.0GB/1.0GB used)`，如何解决？
-
-原因: 底层存储索引数据时默认最大是1G, 如果表数据过多的情况下, 会出现pk数据操作了限制范围
-
-解决:
-
-* 如果是单表离线同步的话, 建议重新建表, 并且在建表时加上`cz.storage.art.max.memory.size.bytes`参数, 具体设置多大, 建议根据表实际大小来按需设置。
-* 如果是多表实时的全量同步报错的话，需要在任务的高级参数中加入`lh.table.cz.storage.art.max.memory.size.bytes`，重新提交任务并启动。
-
-### 问题：任务运行报错 `entity content is too long [320177567] for the configured buffer limit [104857600]`，如何解决？
-
-原因：es 读取数据是通过http 请求批量读取的。es http buffer 有大小限制，默认值是100MB，如果批量的数据大小超过这个限制，则会报错；
-
-解决：
-
-* 降低批量读取的batchSize；
-* 添加高级参数，调大http buffer的大小限制：studio.connector.es.buffer_limit；
-
-说明：降低batchSize会略微降低同步效率，调大studio.connector.es.buffer_limit 则会增加任务使用内存；
-
-### 问题：任务运行报错 `The maximum buffer size of 16777216 is insufficient to read the data of a single field. This issue typically arises when a quotation begins but does not conclude within the confines of this buffer's maximum limit.`，如何解决？
-
-原因：数据集成使用的第三方CSV SDK去读取解析CSV数据，SDK会对数据批量读取，对数据大小有限制，buffer大小默认是16MB；
-
-解决：
-
-添加高级参数：studio.connector.csv_reader.max\_buffer\_size；支持带MB/GB的写法，比如：32MB；
-
-说明：该参数目前仅在OSS/S3 生效；
-
-### 问题：任务运行报错 `Field at index 0 in record starting at line 1 exceeds the max field size of 16777216 characters`，如何解决？
-
-原因：数据集成使用的第三方CSV SDK去读取解析CSV数据，SDK对数据单个字段大小有限制，默认是16MB；
-
-解决：
-
-添加高级参数：studio.connector.csv_reader.max\_field\_size；支持带MB/GB的写法，比如：32MB；
-
-说明：该参数目前仅在OSS/S3 生效；
-
-### 问题：任务运行报错 `Field at index 5 in record starting at line 1 exceeds the max record size of 67108864 characters`，如何解决？
-
-原因：数据集成使用的第三方CSV SDK去读取解析CSV数据，SDK对单条数据大小有限制，默认是64MB；
-
-解决：
-
-添加高级参数：studio.connector.csv_reader.max\_record\_size；支持带MB/GB的写法，比如：128MB；
-
-说明：该参数目前仅在OSS/S3 生效；

-# 数据导入 Lakehouse 操作实践：通过 COPY 命令批量加载
-
-本指南将帮助您通过脚本方式和云器Lakehouse SQLLine命令行工具，将大量公共URL Parquet文件中的数据（例如New York City Taxi and For-Hire Vehicle Data）导入到云器Lakehouse中。
-
-1. download_raw_data.sh：将 Public URL Parquet 文件下载到本地。本文以NYC Taxi Data为例，包含450多个文件，60GB的数据（Parquet格式）。
-
-2. initialize_database.sh：通过 Lakehouse SQLLine 命令创建云器 Lakehouse 的 schema 和 tables。
-
-3. Import taxi and FHV data：用 R 转换 Parquet 文件到 CSV 文件，通过 Lakehouse SQLLine COPY 命令将本地 CSV 文件里的数据导入到云器 Lakehouse 的表里，支持批量多个文件的导入。
-
-# 操作指南
-
-脚本下载地址：<https://github.com/yunqiqiliang/nyc-taxi-data-clickzetta>
-
-## 1. Install [ClickZetta SQLLine](https://doc.clickzetta.com/zh-CN/connect-with-cli)
-
-## 2. Install [R](https://www.r-project.org/)
-
-From [CRAN](https://cloud.r-project.org/)
-
-Note that R used to be optional for this repo, but is required starting with the 2022 file format change. The scripts use R to convert Parquet files to CSV before loading into Postgres. There are other ways to convert from Parquet to CSV that wouldn't require R, but I found that R's `arrow` package was faster than some of the other CLI tools I tried
-
-## 3. Download raw data
-
-`./download_raw_data.sh`
-
-When done, modify download_raw_data.sh and run again to download data from 202212:
-wget -i setup_files/raw_data_urls_new\.txt -P data/ -w 2
-
-## 4. Initialize database and set up schema
-
-`./initialize_database.sh`
-
-## 5. Import taxi and FHV data
-
-`./import_yellow_taxi_trip_data.sh`
-
-`./import_green_taxi_trip_data.sh`
-
-`./import_fhv_taxi_trip_data.sh`
-
-`./import_fhvhv_trip_data.sh`
-
-Note that the full import process might take several hours or possibly even over a day, depending on computing power.
-
-# Schema
-
-* `trips` table contains all yellow and green taxi trips. Each trip has a `cab_type_id`, which references the `cab_types` table and refers to one of `yellow` or `green`
-* `fhv_trips` table contains all for-hire vehicle trip records, including ride-hailing apps Uber, Lyft, Via, and Juno
-* `fhv_bases` maps `fhv_trips` to base names and "doing business as" labels, which include ride-hailing app names
-* `nyct2010` table contains NYC census tracts plus the Newark Airport. It also maps census tracts to NYC's official neighborhood tabulation areas
-* `taxi_zones` table contains the TLC's official taxi zone boundaries. Starting in July 2016, the TLC no longer provides pickup and dropoff coordinates. Instead, each trip comes with taxi zone pickup and dropoff location IDs
-* `central_park_weather_observations` has summary weather data by date

-# Bitmap 类型说明
-
-Bitmap（位图）是云器 Lakehouse 中用于存储和处理集合类型数据的高效数据类型。云器 Lakehouse 中的 Bitmap 是 **64 位的**，使用 Roaring Bitmap 压缩算法进行优化，能够高效地存储和处理大规模的整数集合。
-
-Bitmap 通过位级操作来表示整数集合，提供极高的空间压缩率。相比于直接存储数组，Bitmap 能够显著降低存储成本，同时提供快速的集合操作性能。
-
-### Bitmap 的特点
-
-* **64 位整数支持**：支持存储 0 到 2^64-1 范围内的整数
-* **高效压缩**：使用 Roaring Bitmap 算法，空间占用极小
-* **快速运算**：支持并集、交集、补集等集合操作，性能优异
-* **二进制序列化**：可与 binary 类型相互转换，方便数据交换
-* **灵活查询**：支持集合包含检查、基数计算等操作
-
-## 语法
-
-### 创建包含 Bitmap 列的表
-
-```SQL
-CREATE TABLE table_name (
-    column_name bitmap
-);
-```
-
-**示例**：
-
-```SQL
-CREATE TABLE bitmap_example (
-    user_id bigint,
-    preference_tags bitmap
-);
-```
-
-### 构建 Bitmap 数据
-
-#### 使用 bitmap\_build 函数
-
-从整数数组构建 Bitmap 对象：
-
-```SQL
-bitmap_build(array_expression)
-```
-
-**示例**：
-
-```SQL
-INSERT INTO bitmap_example VALUES
-    (1, bitmap_build(array(1, 3, 5, 7, 9))),
-    (2, bitmap_build(array(2, 4, 6, 8, 10)));
-```
-
-#### 使用 GROUP\_BITMAP\_STATE 函数
-
-根据输入的表达式（expr）构建一个 bitmap 类型的结果，函数通常用于对整数类型的数据进行分组操作，并将每个分组的唯一值转换为一个 bitmap 数组。
-
-```SQL
-GROUP_BITMAP_STATE(expr)
-```
-
-**示例**：
-
-```SQL
-INSERT INTO bitmap_example
-SELECT user_id, group_bitmap_state(v) AS bitmap_array
-FROM VALUES (1, 1), (1, 2), (1, 2), (2, 3) AS v(user_id, v)
-GROUP BY user_id;
-```
-
-## 注意事项
-
-### 功能限制
-
-1. **不支持比较操作**：Bitmap 类型不支持直接的比较操作（<、>、=、!=等）
-2. **不支持排序和分组**：Bitmap 列不能用于 ORDER BY、GROUP BY 或 DISTINCT 操作
-3. **不支持作为键**：Bitmap 不能作为表的 PRIMARY KEY、PARTITION KEY 或 CLUSTER KEY
-4. **查询屏显示**：clickzetta-java 的版本是 >3.0.21
-
-### 数据有效性
-
-1. **有效的整数范围**：bitmap\_build 函数的输入数组必须包含有效的整数值
-2. **Binary 转换**：使用 binary\_to\_bitmap 进行转换时，输入的 binary 数据使用bitmap\_to\_binary转化必须是有效的 Bitmap 序列化格式
-3. **空值处理**：Bitmap 本身可以是 NULL，但数组中的 NULL 值会被忽略
-
-### 性能考虑
-
-1. **适用场景**：Bitmap 最适合存储稀疏的整数集合或大整数集合
-2. **集合运算**：大规模的集合运算应在数据库层完成，而不是在应用层处理
-

-
-## 使用 SDK 方式写入 Bitmap 数据
-
-### Java SDK 示例
-
-使用 ClickZetta Java SDK 中的 BulkloadStream 来批量写入 Bitmap 数据。需要使用 `RoaringBitmap` 构建 Bitmap 对象。
-
-**构建bitmap对象**：
-
-```Java
-import org.roaringbitmap.longlong.Roaring64NavigableMap;
-Roaring64NavigableMap roaring64Bitmap = new Roaring64NavigableMap();
-roaring64Bitmap.add(1);
-roaring64Bitmap.add(3);
-roaring64Bitmap.add(5);
-roaring64Bitmap.add(7);
-row.setValue("preference_tags", roaring64Bitmap);
-```
-
-**Maven 依赖**
-
-在 `pom.xml` 中添加以下依赖要求版本大于3.0.23：
-
-```XML
-<dependency>
-    <groupId>com.clickzetta</groupId>
-    <artifactId>clickzetta-java</artifactId>
-    <version>${version}</version>
-</dependency>
-```
-
-### Python SDK 示例
-
-**Python依赖**：
-
-```python
-pip install clickzetta clickzetta-ingestion pyroaring
-```
-
-**构建bitmap对象**：
-
-```python
-tags = [i for i in range(1, 21, 2)]
-bitmap = pyroaring.BitMap64(tags)
-row.set_value('preference_tags', bitmap)
-```
-
-## 最佳实践
-
-1. **选择合适的数据类型**：当需要存储整数集合时，优先考虑 Bitmap，尤其是集合较大或稀疏的场景
-
-2. **在数据库层完成运算**：充分利用 Bitmap 的集合运算函数，在数据库层完成交集、并集等操作，减少数据传输
-
-3. **合理使用转换函数**：
-
-   1. 使用 `bitmap_to_array` 进行展示和调试
-   2. 使用 `bitmap_to_binary` 进行持久化存储
-
-4. **性能优化**：
-
-   1. 对大规模数据集进行集合运算时，使用 Bitmap 而非 Array
-   2. 使用 `bitmap_cardinality` 进行计数而非转换为数组后计数

-
-## 🎯 业务场景实战案例
-
-### 场景1: 多渠道用户重叠分析
-
-#### 💡 为什么要做这个分析？
-
-营销团队在多个渠道（Facebook、Google、TikTok等）投放广告获取用户，但面临以下挑战：
-
-* **重复投放成本**: 不知道有多少用户在多个渠道都看到了广告，造成预算浪费
-* **渠道效果对比**: 无法准确评估哪个渠道带来的是独有用户，哪个渠道主要是重复用户
-* **投放策略优化**: 需要了解用户重叠程度来调整各渠道的投放比例和预算分配
-* **精准营销**: 识别只在单一渠道活跃的用户，进行针对性的跨渠道营销
-
-通过BITMAP函数可以高效计算数百万用户在不同渠道间的重叠情况，为营销决策提供数据支撑。
-
-#### 1.1 建表准备
-
-```sql
--- 创建用户活动表
-CREATE TABLE IF NOT EXISTS user_activity (
-    user_id BIGINT,
-    channel STRING,
-    activity_date DATE,
-    event_type STRING
-) PARTITIONED BY (activity_date);
-
--- 插入示例数据
-INSERT INTO user_activity VALUES
-(1001, 'facebook', DATE('2024-01-15'), 'register'),
-(1002, 'google', DATE('2024-01-15'), 'register'),
-(1003, 'tiktok', DATE('2024-01-15'), 'register'),
-(1001, 'google', DATE('2024-01-16'), 'login'),
-(1004, 'facebook', DATE('2024-01-16'), 'register'),
-(1005, 'google', DATE('2024-01-16'), 'register'),
-(1006, 'tiktok', DATE('2024-01-16'), 'register'),
-(1007, 'facebook', DATE('2024-01-17'), 'register'),
-(1008, 'google', DATE('2024-01-17'), 'register'),
-(1009, 'tiktok', DATE('2024-01-17'), 'register'),
-(1002, 'tiktok', DATE('2024-01-17'), 'login');
-```
-
-#### 1.2 渠道用户重叠分析
-
-< c2.channel;
-```
-
-**预期结果**: 返回重叠用户ID [1001]，符合业务逻辑。
-
-### 场景2: 用户兴趣推荐系统
-
-#### 💡 为什么要做这个分析？
-
-电商平台面临个性化推荐的挑战：
-
-* **商品推荐精准度**: 需要基于用户真实的购买和浏览行为，而不是简单的热门商品推荐
-* **相似用户发现**: 识别兴趣相似的用户群体，实现协同过滤推荐
-* **新用户冷启动**: 通过分析用户初期行为，快速找到相似用户进行推荐
-* **推荐多样性**: 在保证相关性的同时，避免推荐内容过于单一
-* **实时性要求**: 用户行为变化后，需要快速更新推荐结果
-
-使用BITMAP函数可以高效计算用户兴趣向量的相似度，支撑实时推荐系统的运行。
-
-#### 2.1 建表准备
-
-```sql
--- 创建用户行为表
-CREATE TABLE IF NOT EXISTS user_behavior (
-    user_id BIGINT,
-    item_id BIGINT,
-    behavior_type STRING,  -- 'view', 'cart', 'purchase'

-# BloomFilter Index
-## Bloom Filter索引的原理介绍
-1. **数据结构**：Bloom Filter 由一个位数组（BitSet）和多个哈希函数组成。位数组初始时所有位都设置为 0。
-2. **元素添加**：当向集合中添加一个元素时，通过多个哈希函数计算出该元素在位数组中的多个位置，并将这些位置的位设置为1。
-3. **元素查询**：查询元素是否存在时，同样通过哈希函数计算出该元素可能在位数组中的位置，检查这些位置是否都为1。如果所有位都为1，则认为元素可能存在于集合中；如果任何一个位不为1，则可以确定元素不存在于集合中。
-4. **优点**：
-   * 空间效率和查询时间都远远超过一般算法，存储空间和插入/查询时间都是常数 O(k)。
-   * 哈希函数相互之间没有关系，方便硬件并行实现。
-   * 不需要存储元素本身，在对保密要求严格的场合有优势。
-5. **缺点**：
-   * 随着存入的元素数量增加，误判率随之增加，即假阳性（False Positive）概率增加。
-   * 一般情况下不能从Bloom Filter中删除元素。
-6. **应用场景**：
-   * Bloom Filter 索引适用于基数较高的列，如 ID 列，可以快速判断表的数据文件中是否可能包含要查询的数据，如果不包含就跳过，从而减少扫描的数据量。
-   * 适用于等值查询（包括 = 和 IN），对高基数字段效果较好，如 USER-ID 等唯一 ID 字段。对低基数字段的加速效果有限，如“性别”字段。
-
-7. **误判率（False Positive）**：Bloom Filter 可能出现将不在集合中的元素误判为在集合中的情况，但绝不会出现将集合中的元素误判为不在集合中的情况。
-## Bloom Filter在Lakehouse中的应用
-
-Bloom Filter 索引是一种高效的数据结构，用于快速判断数据文件中是否包含特定的数据。通过为某个列创建 Bloom Filter 索引，系统会为该列生成一个 Bloom Filter。在执行查询操作时，可以利用这个索引跳过不需要的数据文件，从而减少扫描数据量，提高查询性能。Bloom Filter 特别适用于基数较高的列。
-
-例如，当执行一个查询操作，如 `SELECT * FROM table WHERE col_name = 'xxx'`，BloomFilter 会先判断目标数据文件中是否可能包含该值。如果不可能存在，系统将跳过该文件，避免不必要的读取。如果索引判断文件中可能存在目标数据，则会读取文件进行进一步查询。
-
-BloomFilter 索引在以下操作中生效：`AND`, `OR`, `IN`, `=`。需要注意的是，创建完 Bloom Filter 索引后，只有新写入的数据才会包含该索引。对于旧数据，建议使用 `INSERT OVERWRITE` 语句进行重写，以添加索引。
-
-### Bloom Filter具体使用场景
-
-**场景一：大数据量下的等值查询**
-
-**案例**：
-假设有一个用户表 `users`，其中包含数百万条用户记录，表结构如下：
-
-```SQL
-CREATE TABLE users (
-    user_id INT,
-    username VARCHAR(255),
-    email VARCHAR(255)
-);
-```
-
-在这个表中，`email` 字段的基数很高，即大多数用户都有唯一的邮箱地址。如果我们经常需要根据邮箱地址来查询用户信息，可以为 `email` 字段创建一个 Bloom Filter 索引。
-
-**创建索引**：
-
-```SQL
-CREATE BLOOMFILTER INDEX idx_email ON TABLE users(email);
-```
-
-**查询**：
-
-当我们需要查询特定邮箱的用户时，可以使用如下查询：
-
-```SQL
-SELECT * FROM users WHERE email = 'user@example.com';
-```
-
-* **快速排除**：Bloom Filter 可以帮助数据库快速判断 `user@example.com` 是否可能在表中。如果 Bloom Filter 确定该邮箱不可能在表中，那么相关的数据文件将被跳过，从而减少 I/O 操作和查询时间。
-* **提升性能**：对于大数据量的表，这种快速排除可以显著提升查询性能。
-
-**场景二：高基数列的查询优化**
-
-**案例**：
-
-假设有一个商品表`products`，其中包含商品的各种属性，表结构如下：
-
-```SQL
-CREATE TABLE products (
-    product_id INT,
-    category VARCHAR(100),
-    price DECIMAL(10, 2)
-);
-```
-
-在这个表中，`category` 字段的基数非常高，因为商品可以属于不同的类别。如果我们经常需要根据类别来查询商品，可以为 `category` 字段创建一个 Bloom Filter 索引。
-
-**创建索引**：
-
-```SQL
-CREATE BLOOMFILTER INDEX idx_category ON TABLE products(category);
-```
-
-**查询**：
-
-当我们需要查询特定类别的商品时，可以使用如下查询：
-
-```SQL
-SELECT * FROM products WHERE category = 'Electronics';
-```
-
-*   **减少扫描**：Bloom Filter 可以减少需要扫描的数据量，因为对于不包含目标类别的数据文件，Bloom Filter 可以帮助跳过它们。
-*   **提高效率**：在高基数列上，Bloom Filter 可以提高查询效率，尤其是在数据量庞大的情况下。
-
-### 注意事项
-
-* **误报概率**：Bloom Filter有一个定义的误报概率（FPP），这意味着它可能会错误地认为某个值存在于表中。因此，即使Bloom Filter表明某个值可能存在，实际查询时仍可能找不到该值。
-* **写操作成本**：Bloom Filter 在写操作（如插入、更新、删除）时可能会有更高的成本，因为需要更新 Bloom Filter 数据结构。
-* **不支持的数据类型**：Bloom Filter不支持interval、struct、map、array等复杂数据类型，因此在创建索引时需要注意列的数据类型。
-
-
-## 创建 Bloom Filter 索引
-
-[创建 BloomFilter索引](<CREATE-BLOOMFILTER-INDEX.md>)
-
-要为某个列创建 Bloom Filter 索引，您可以使用以下语句：
-
-```
-CREATE BLOOMFILTER INDEX index_name ON table_name (column_name);
-```
-
-例如，为表 `employees` 中的 `email` 列创建一个名为 `email_bloomfilter` 的索引：
-
-```
-CREATE BLOOMFILTER INDEX email_bloomfilter ON employees (email);
-```

-## 构建索引
-
-对存量数据添加索引。目前只支持向量索引和倒排索引，不支持布隆过滤器。
-
-## 语法
-
-```SQL
--- 语法 1，默认给全表的存量数据加上索引
-BUILD INDEX index_name ON [schema].table_name;
--- 语法 2，可指定partition，可指定一个或多个,支持=, !=, >, >=, <, <=
-BUILD INDEX index_name ON table_name WHERE partition_name1 = '1' and partition_name2 = '2';
-```
-
-* `index_name`：指定要添加的索引名称
-* 支持指定分区构建：可以指定一个或多个分区
-
-## 说明
-
-执行 `BUILD INDEX` 是一个同步任务，执行过程会消耗计算资源。查看进度可以通过 Job Profile。
-
-当分区表数据量较大时，建议以分区为粒度依次创建索引。
-
-## 案例
-
-```SQL
-BUILD INDEX bulkload_data_index ON public.bulkload_data ;
-```

-# 构建RAG应用完整指南
-
-本教程将指导您使用 LangChain 和 ClickZetta 构建一个完整的检索增强生成（RAG）应用。我们将构建一个智能文档问答系统。
-
-## 🎯 项目目标
-
-构建一个企业级RAG应用，具备以下功能：
-- 文档上传和向量化存储
-- 智能文档检索
-- 基于上下文的问答生成
-- 聊天历史管理
-- 混合搜索能力（向量+全文）
-
-## 📋 技术栈
-
-- **数据存储**: ClickZetta（向量存储、全文索引、聊天历史）
-- **嵌入模型**: 灵积DashScope text-embedding-v4
-- **大语言模型**: 通义千问 qwen-plus
-- **框架**: LangChain + ClickZetta 集成
-
-## 🏗️ 架构设计
-
-```
-用户查询 → 混合检索 → 上下文增强 → LLM生成 → 返回答案
-    ↓           ↓            ↓          ↓
-聊天历史 → 向量搜索+全文搜索 → 排序重组 → 历史记忆
-```

-## 📈 性能优化建议
-
-### 1. 数据存储优化
-
-```python
-# 使用分区表提高查询性能
-create_partitioned_table_sql = """
-CREATE TABLE rag_documents_partitioned (
-    id String,
-    content String,
-    embedding Array(Float32),
-    metadata String,
-    created_at Timestamp DEFAULT CURRENT_TIMESTAMP
-)
-PARTITION BY toYYYYMM(created_at)

-
-### 2. 检索优化
-
-```python
-# 缓存频繁查询的结果
-from functools import lru_cache
-
-class CachedRetriever:
-    def __init__(self, retriever):
-        self.retriever = retriever
-
-    @lru_cache(maxsize=100)
-    def cached_search(self, query: str, k: int = 5):
-        return self.retriever.invoke(query)
-```

-# Lakehouse Bulkload 快速入门
-
-## 简介
-
-Bulkload 是 Lakehouse 提供的一种面向高吞吐量设计的批量数据写入接口，特别适合处理大量连续写入的场景。使用 Bulkload 写入的数据在提交后即可查看。
-
-## 批量导入原理
-
-批量上传 SDK 提供了一种高效的数据导入机制，适用于云器 Lakehouse。以下是其工作原理的简化描述和流程图：
-
-1. **数据上传**：通过SDK，您的数据首先被上传到对象存储服务。这一步骤的性能受到本地网络速度和并发连接数的影响。
-2. **触发导入**：数据上传完成后，当您调用`bulkloadStream.close()`方法时，SDK会自动触发一个SQL命令，将数据从对象存储导入到Lakehouse的表中。不建议您在一个任务中频繁调用`bulkloadStream.close()`，该方法最终只能调用一次。
-3. **计算资源**：上传数据建议选择[通用型计算集群](../create_cluster.md)（GENERAL PURPOSE VIRTUAL CLUSTER）通用型计算资源，它更适合运行批量作业和加载数据作业。数据从对象存储到Lakehouse表的导入速度取决于您配置的计算资源的大小。
-4. **分片上传优化**：处理大于1GB的压缩数据时，建议在`createRow`方法中为每个并发线程或进程分配唯一的分片ID。这种做法能够充分发挥多线程或多进程的并行处理优势，显著提升数据导入效率。最佳实践是根据并发数量来确定分片 ID 的数量，确保每个并发任务对应一个独立的分片 ID。如果多个并发任务被分配了相同的分片 ID，最终写入的数据可能会发生覆盖，导致先前写入的数据丢失。为确保所有分片的数据都被正确导入表中，请在所有并发操作完成后，调用`bulkloadStream.close()`方法来提交整个导入任务。
-
-以下是批量导入原理的流程图：
-
-```
-[SDK上传数据] ──> [对象存储] ──> [调用bulkloadStream.close()]
-                                ↓
-                         [触发SQL命令] ──> [Lakehouse表]
-```
-
-## 适用场景
-
-批量上传文件的 SDK 特别适用于以下情况：
-
-* **一次性大量数据导入**：当您需要导入大量数据时，无论是一次性的批量任务，还是周期性但间隔较长的操作。
-* **导入频率不高**：如果您的数据导入频率不高（时间间隔大于五分钟），即使单次导入的数据量不大，使用批量导入 SDK 也是合适的。
-
-## 不适用场景
-
-批量上传文件的 SDK 不适用于以下情况：
-
-* **实时数据导入**：如果您需要在极短时间内（如5分钟之内）频繁导入数据，建议使用实时数据接口，以满足对实时性的要求。

-* [下载地址二](https://mvnrepository.com/artifact/com.clickzetta/clickzetta-java)
-
-
-## 创建 BulkloadStream
-
-要通过 ClickZetta 客户端创建一个批量写入流，请参考以下示例代码：
-
-```java
-RowStream stream = client.newBulkloadStreamBuilder()
-        .schema(schema)
-        .table(TABLE_NAME)
-        .operate(RowStream.BulkLoadOperate.APPEND)
-        .build();
-```
-
-### Options
-
-在clickzetta-java版本3.0.18以后提供了options。options用于指定上传选项入指定分取
-
-```
-bulkloadStream=client.newBulkloadStreamBuilder().schema(schema).table(table)
-                .options(BulkLoadOptions.newBuilder().withPartitionSpecs(Optional.of("your_partition_spec")).build())
-
-                .operate(RowStream.BulkLoadOperate.APPEND)
-                .build();
-```
-
-* withPartitionSpecs 用于指定目标表的分区信息，控制数据写入的分区行为。
-
-  * 非分区表：忽略此参数或设置为
-  * 分区表：
-    * 静态分区写入，需要将所有数据写入指定的固定分区，无论源数据中分区列的实际值是什么，写入目标表时都会使用 `partition_spec` 指定的分区值，所有数据都会写入到同一个指定分区中。参数格式是'分区列1=值1,分区列2=值2'
-      - 动态分区写入，根据数据中分区列的实际值，自动写入到对应分区。忽略此参数，系统根据数据中分区列的值自动创建或写入相应分区
-
-### 操作类型
-
-在创建 Bulkload 时，可以通过 `operate` 方法指定以下操作类型：
-
-* `RowStream.BulkLoadOperate.APPEND`：追加模式，向表中添加数据。
-  ```
-  bulkloadStream=client.newBulkloadStreamBuilder().schema(schema).table(table)
-          .operate(RowStream.BulkLoadOperate.APPEND)
-          .build();
-  ```
-
-* `RowStream.BulkLoadOperate.OVERWRITE`：覆盖模式，删除表中现有数据后再写入新数据。
-  ```
-  bulkloadStream=client.newBulkloadStreamBuilder().schema(schema).table(table)
-          .operate(RowStream.BulkLoadOperate.OVERWRITE)
-          .build();
-  ```
-
-## 写入数据
-
-使用 Row 对象表示要写入的具体数据。通过调用 `row.setValue` 方法将数据封装到 Row 对象中。
-
-```java
-Row row = stream.createRow(0);
-row.setValue("id", t);
-row.setValue("name", String.valueOf(t));
-stream.apply(row, 0);
-```
-
-* `createRow` 方法创建 Row 对象时，需要传入一个整数作为分片 ID。这个 ID 可以配合多线程/进程技术，用多个互补相同的分片 ID 来写入数据，从而有效提升写入数据的速度。
-* `setValue` 方法的第一个参数为字段名，第二个参数为具体的数据。要求数据类型与表类型一致。
-* `apply` 方法用于写入数据，需要指定 Row 对象以及相应的分片 ID。
-
-### 写入复杂类型数据
-
-```java
-// 写入数组
-row.setValue("col1", Arrays.asList("first", "b", "c"));
-
-// 写入映射
-final HashMap<Integer, String> map = new HashMap<Integer, String>();
-map.put(t, "first" + t);
-row.setValue("col2", map);
-
-// 写入结构体
-Map<String, Object> struct = new HashMap<>();
-struct.put("first", "first-" + i);
-struct.put("second", i);
-row.setValue("col3", struct);
-```
-
-## 提交数据
-
-批量写入的数据只有在提交之后才可见。因此，提交过程非常重要。
-
-```java
-bulkloadStream.close();
-```
-
-* 通过 `bulkloadStream.getState()` 获取 BulkloadStream 的状态。
-* 如果提交失败，可以通过 `bulkloadStream.getErrorMessage()` 获取错误信息。
-
-## 使用示例
-
-以下是一个使用 Bulkload 写入复杂类型数据的示例：
-
-```java
-// 建表 create table complex_type(col1 array<string>,col2 map<int,string>, col3 struct<x:int,y:int>);
-import com.clickzetta.client.ClickZettaClient;
-import com.clickzetta.client.RowStream;
-import com.clickzetta.platform.client.api.Options;
-import com.clickzetta.platform.client.api.Row;
-import com.clickzetta.platform.client.api.Stream;
-
-public class BulkloadStreamDemo {
-    public static void main(String[] args) throws Exception{
-        if (args.length != 5) {
-            System.out.println("input arguments: jdbcUrl, username, password");
-            System.exit(1);
-        }
-        String jdbcUrl = args[0];
-        String username = args[1];
-        String password = args[2];
-        String schema = args[3];
-        String table = args[4];
-
-        ClickZettaClient client = ClickZettaClient.newBuilder().url(jdbcUrl).username(username).password(password).build();
-
-
-        BulkloadStream bulkloadStream = client.newBulkloadStreamBuilder()
-                .schema(schema)
-                .table(table)
-                .operate(RowStream.BulkLoadOperate.APPEND)
-                .build();
-
-        for (int t = 0; t < 100; t++) {
-            Row row = bulkloadStream.createRow(0);
-            row.setValue("col1", Arrays.asList("first", "b", "c"));
-            final HashMap<Integer, String> map = new HashMap<Integer, String>();
-            map.put(t,"first"+t);
-            row.setValue("col2", map);
-            Map<String, Object> struct = new HashMap<>();
-            struct.put("x", t);
-            struct.put("y", t+1);
-            row.setValue("col3", struct);
-            bulkloadStream.apply(row, 0);
-        }
-        // 必须调用 stream close 接口，触发提交动作
-        bulkloadStream.close();
-
-        // 轮训提交状态，等待提交结束
-        while(bulkloadStream.getState() == StreamState.RUNNING) {
-            Thread.sleep(1000);
-        }
-        if (bulkloadStream.getState() == StreamState.FAILED) {
-            throw new RuntimeException(bulkloadStream.getErrorMessage());
-        }
-        client.close();
-    }

-# 使用 Python 批量上传数据（BulkLoadV1）
-
-
-
-Clickzetta Lakehouse 通过 `clickzetta-connector` 包提供了使用 Python 语言进行批量数据上传（Bulkload）的 API。该 API 使得数据可以直接从客户端发送到存储系统，传输过程不消耗计算资源，数据在显式 commit 后可见（commit 过程会消耗少量计算资源）。适用于高吞吐、对数据新鲜度（data freshness）要求相对宽松的场景。
-
-通过 Bulkload 相关 API，可以实现单线程数据上传。
-
-安装
-
-如果安装过旧版本的 SDK，先卸载避免冲突：
-
-```shell
-pip uninstall clickzetta-connector clickzetta-connector-python clickzetta-sqlalchemy clickzetta-ingestion-python clickzetta-ingestion-python-v2 -y
-```
-
-> 卸载前请记录好旧版本的包，以防需要回退。查看已安装包版本命令：
-
-```shell
-pip show clickzetta-connector clickzetta-sqlalchemy clickzetta-ingestion-python clickzetta-ingestion-python-v2 clickzetta-connector-python
-```
-
-安装最新版本（要求 Python >=3.7）：
-
-```bash
-pip install clickzetta-connector -U -i https://pypi.org/simple/
-```
-

-2. 创建 `BulkLoad Stream` 对象，指定上传的目标表、上传方式等：
-   **必选参数**
-   * `table`：表名称
-   **可选参数**
-   * `schema`：如未指定，则使用 `connection` 对象中指定的 `schema`
-    * `operation`
-        * `BulkLoadOperation.APPEND`：增量模式（写入的数据都作为新数据，不对已有数据有任何影响）
-        * `BulkLoadOperation.OVERWRITE`：覆盖模式（清空已有表数据，将新数据写入表中）
-
-* `partition_spec`：用于指定目标表的分区信息，控制数据写入的分区行为。
-    * 非分区表：忽略此参数或设置为空。
-    * 分区表：
-        * 静态分区写入：需要将所有数据写入指定的固定分区。无论源数据中分区列的实际值是什么，写入目标表时都会使用 `partition_spec` 指定的分区值，所有数据都会写入到同一个指定分区中。参数格式为 '分区列1=值1,分区列2=值2'。
-        * 动态分区写入：根据数据中分区列的实际值，自动写入到对应分区。忽略此参数，系统根据数据中分区列的值自动创建或写入相应分区。
-
-  ```python
-
-  from clickzetta.bulkload.bulkload_enums import BulkLoadOperation
-
-  # APPEND 模式构建，默认 operation 即为 APPEND
-  bulkload_stream = conn.create_bulkload_stream(schema='public', table='bulkload_append_test')
-
-
-
-  # OVERWRITE 模式构建
-  bulkload_stream = conn.create_bulkload_stream(
-      schema='public',
-      table='bulkload_overwrite_test',
-      partition_spec='pt=2023-07-01',
-      operation=BulkLoadOperation.OVERWRITE
-  )
-  ```
-
-3. 创建 `writer` 并写入数据：
-   每个 `bulkload stream` 可以创建多个 `writer`，不同的 `writer` 需要用不同的 id 标识。使用多个 `writer` 可以实现在一次 commit 中多线程并发写入的场景。
-   ```python
-   # 利用 `open_writer` 方法创建 `writer`，参数为 `writer` id。单机模式下，只有一个 `writer` id 即可，直接传入 0.
-   writer = bulkload_stream.open_writer(0)
-   ```
-4. 写入数据：
-   ```python
-   # 每一行数据都需要用 create_row() 方法创建 Row 对象，然后用 set_value() 方法写入具体数据。
-   # set_value() 第一个参数为列名，第二个参数为值
-   row = writer.create_row()
-   row.set_value('i', 1)
-   row.set_value('s', 'January')
-   row.set_value('d', 123.456)
-   writer.write(row)
-   ```
-   通过 writer 写入的数据将直接在存储系统中形成相应的 parquet 文件。writer 将根据写入的数据量自动进行文件切割。当 writer 写入数据结束后，需要显式调用 writer.close() 来保证数据完整性。
-   ```python
-   writer.close()
-   ```
-5. 提交 stream。commit 前需要确保各 writer 均已完成写入并关闭。commit 成功后数据在表中可见。
-   ```python
-   bulkload_stream.commit()
-   ```

-# 私有存储（BYOS）
-> 【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请联系我们的技术支持同学协助处理。
-## 一、功能概述
-
-私有存储BYOS（Bring Your Own Storage）功能允许您使用自己的对象存储服务作为ClickZetta Lakehouse的数据存储位置。通过此功能，您可以：
-
-* 在Web界面完成私有存储配置，无需复杂的技术操作；
-* 将工作空间数据存储在您自己云平台账号管理的对象存储中；
-* 自主管理存储成本和存储策略。
-
-## 二、适用场景
-
-BYOS功能适合以下场景：
-
-1. **数据合规要求**：需要将数据存储在自有云账号的对象存储内，以满足合规要求；
-2. **数据主权**：需要完全掌控数据的存储位置和访问权限；
-3. **混合部署**：部分工作空间使用托管存储，部分合规要求高的工作空间使用自有存储。
-
-## 三、前置准备
-
-### 3.1 创建存储桶（Bucket）
-
-在配置BYOS前，您需要先创建符合要求的存储桶：
-
-#### 必须满足的条件：
-
-| 配置项      | 要求                         | 说明                     |
-| -------- | -------------------------- | ---------------------- |
-| **所属区域** | 与Lakehouse实例同一云厂商、同一Region | 避免跨区域传输费用              |
-| **存储类型** | 标准存储                       | 不要使用低频或归档存储，避免产生额外访问费用 |
-| **读写权限** | 私有（私有读写）                   | 确保数据安全                 |
-| **独占使用** | 专用于Lakehouse               | 不可与其他业务系统共用，避免数据冲突     |
-
-#### 存储桶（bucket）建议配置：
-
-| 配置项        | 建议值  | 说明                                             |
-| ---------- | ---- | ---------------------------------------------- |
-| **存储冗余**   | 按需选择 | 本地冗余存储可满足基本需求；高可用要求可选同城冗余。                     |
-| **版本控制**   | 关闭   | Lakehouse已自行管理数据版本，开启可能产生额外费用。                 |
-| **服务端加密**  | 关闭   | Lakehouse会根据工作空间配置，对部分数据单独开启加密。全局开启加密可能影响读写性能。 |
-| **生命周期规则** | 不配置  | Lakehouse自行管理文件生命周期。                           |
-
-### 3.2 创建访问策略
-
-您需要为ClickZetta Lakehouse子账号授权访问您的存储桶。具体的授权策略详见——
-
-## 四、配置步骤
-
-### 步骤1：进入私有存储管理
-
-:-: ![](/.topwrite/assets/image_1760181980735.png =759)
-
-1. 登录ClickZetta Lakehouse控制台
-2. 进入【管理】→【更多】→【私有存储】页面
-3. 点击【+新建】按钮
-
-### 步骤2：填写存储信息
-
-![](/.topwrite/assets/image_1760182222984.png)
-
-在弹出的配置窗口中填写：
-
-1）名称【必填】：以字母（AZ、az）或下划线（“\_”）开头，长度为3\~28个字符。须在您的服务实例内唯一。保存后不可更改。
-
-2）主账号【必填】：输入您在云平台中的账号ID，以便调用云平台接口时使用您授权的角色和Bucket。可在登录云平台账号后找到并复制。
-
-&#x20;     阿里云：
-
-:-: ![](/.topwrite/assets/image_1760182500707.png =253)
-
-&#x20;   腾讯云：
-
-:-: ![](/.topwrite/assets/image_1760182704445.png =250)
-
-3）Bucket名称【必填】：输入您希望使用的Bucket名称，或者Bucket名称+路径。Bucket名称+路径的写法示例为：
-
-```
-bucket_name/subpath
-```
-
-4）描述【非必填】：对私有存储的描述，可帮助使用者了解该私有存储的业务用途，避免误操作。
-
-完成上述信息的填写后，点击“确定”按钮，即完成私有存储的创建。
-
-一个Lakehouse服务实例下可以创建多个私有存储。
-
-### 步骤3：校验配置
-
-创建完成后，私有存储的默认连通状态为“失败”，需要点击私有存储右侧的“测试联通”按钮，测试私有存储的连通性。Lakehouse测试连通性时将进行的操作是：使用Lakehouse在云平台的账号调用同云平台同region的HeadBucket/GetBucketInfo等相似功能的接口，确认：
-
-* 存储桶（Bucket）是否存在；
-* 所在地域是否正确；
-* 访问权限是否配置正确。
-
-校验通过后，列表中该私有存储的连接状态变为“成功”。
-
-### 步骤5：关联工作空间
-
-在创建新的工作空间时，可使用已有的私有存储作为该工作空间的存储位置。
-
-1）在新建工作空间弹窗中，点击并展开【高级设置】；
-
-:-: ![](/.topwrite/assets/image_1760183458961.png =516)
-
-2）打开私有存储开关，选择已有的私有存储位置。一个私有存储位置可以关联多个工作空间。多个工作空间的数据会在该存储桶（bucket）下的子路径中区分开，不会互相影响。
-
-:-: ![](/.topwrite/assets/image_1760183572318.png =516)
-
-3）点击“确定”完成工作空间创建。
-
-## 五、重要限制
-
-### 5.1 功能限制
-
-* 工作空间关联存储后**不可更改**；
-* 已关联工作空间的私有存储位置**不可删除**，须先删除工作空间后才可删除。
-
-### 5.2 区域限制
-
-* 仅支持同一云厂商、同一Region的存储桶；
-* AWS环境需确保在同一可用区，避免跨区流量费用。
-
-### 5.3 责任边界
-
-* 使用私有存储时，私有存储指向存储桶（bucket）的可用性和可靠性由您自行负责；
-* 非经由ClickZetta操作造成的数据问题需由您自行承担。
-
-### 5.4 费用说明
-
-使用BYOS后：
-
-* ClickZetta不再收取私有存储中的存储容量费用，仍继续收取其他托管存储位置中的存储费用。
-* 您需直接向云厂商支付：
-  * 存储容量费用
-  * API访问费用
-  * 公网流量费用（如有）
-* 日志和临时文件将占用您的存储空间
-
-### 5.5 性能注意
-
-* 存储性能直接影响Lakehouse运行效率
-* 需确保存储服务的QPS和带宽满足需求
-* 避免与其他业务争抢存储资源
-
-^
-
-## 六、常见问题
-
-**Q1: 可以将现有工作空间迁移到BYOS吗**？&#x20;
-
-A: 不可以。工作空间的存储位置一旦确定就不能更改。
-
-^
-
-**Q2: 一个存储桶可以被多个工作空间使用吗**？
-
-A: 可以。一个BYOS配置可以关联多个工作空间，但建议根据实际需求合理规划。
-
-^
-
-**Q3: 使用BYOS后，ClickZetta还会产生哪些存储**？&#x20;
-
-A: 查询缓存、临时文件等会存储在您的存储桶中，这部分会占用一定容量。

-# 终止作业
-
-## 功能描述
-
-本功能允许用户终止正在运行的作业或取消某个虚拟集群下的所有作业。通过该功能，用户可以有效地管理作业进度，避免资源浪费。
-
-## 语法说明
-
-```
--- 取消单个作业
-CANCEL JOB 'jobid';
-
--- 取消某个VIRTUAL CLUSTER下所有作业
-ALTER VCLUSTER [ IF EXISTS ] vc_name CANCEL ALL JOBS;
-```
-
-## 参数说明
-
-1. `jobid`：作业运行的唯一标识符，字符串格式。作业运行时，日志会打印出jobid，同时在[show jobs](<show-jobs.md>)命令中也会显示相应的jobid。
-2. `vc_name`：指定的虚拟集群名称。如果虚拟集群不存在，使用`IF EXISTS`选项可以避免因找不到集群而产生错误。
-
-## 使用示例
-
-### 示例1：取消单个作业
-
-假设您需要取消一个作业，其jobid为`201xxxxxxxxxx`。您可以使用以下命令实现：
-
-```
-CANCEL JOB '201xxxxxxxxxx';
-```
-
-### 示例2：取消某个虚拟集群下所有作业
-
-假设您需要取消名为`my_vc`的虚拟集群下的所有作业。首先，使用以下命令取消该虚拟集群下的所有作业：
-
-```
-ALTER VCLUSTER my_vc CANCEL ALL JOBS;
-```
-
-如果担心虚拟集群不存在导致错误，可以使用`IF EXISTS`选项：
-
-```
-ALTER VCLUSTER IF EXISTS my_vc CANCEL ALL JOBS;
-```
-
-## 注意事项
-
-* 确保在执行终止作业操作时，输入正确的`jobid`或`vc_name`，以免影响其他作业或虚拟集群的正常运行。
-* 终止作业后，已使用的资源将被释放，但请注意，已消耗的时间和费用可能无法退回。

-CREATE TABLE students (
-  id INT,
-  name VARCHAR,
-  hobbies ARRAY<VARCHAR>
-);
-```
-向 `students` 表中插入一条数据：
-```
-INSERT INTO students (id, name, hobbies) VALUES (1, 'Alice', ARRAY('reading', 'swimming', 'traveling'));
-```
-使用 `CARDINALITY` 函数计算该学生的爱好数量：
-```

-
-### 关键洞察
-
-* **问题定位时间**: <= '2025-09-08'
-   GROUP BY date(measurement_start)
-   ORDER BY usage_date
-   ```
-
-2. **异常模式识别**
-
-**历史费用趋势分析**：
-
-| 时间段        | 日均费用       | 费用范围              | 状态          |
-| ---------- | ---------- | ----------------- | ----------- |
-| 8月25日-9月2日 | ¥1.8       | ¥0.99-¥6.06       | ✅ 正常基线      |
-| 9月3日       | ¥25.13     | -                 | ⚠️ 首次异常     |
-| **9月4-5日** | **¥76.21** | **¥66.65-¥85.77** | 🚨 **严重异常** |
-| 9月6日后      | ¥0.73      | ¥0.53-¥1.05       | ✅ 恢复正常      |
-
-3. **使用模式变化分析**
-
-   ```sql
-   SELECT 
-       date(measurement_start) as usage_date,
-       sku_name,
-       count(*) as record_count,
-       sum(measurements_consumption) as total_consumption_hours,
-       avg(measurements_consumption) as avg_consumption_per_record,
-       sum(total_after_discount) as total_cost
-   FROM sys.information_schema.instance_usage 
-   WHERE sku_category = 'compute'
-   GROUP BY date(measurement_start), sku_name
-   ```
-
-**GP集群使用模式对比**：
-
-| 日期       | 平均每小时消费     | 记录数     | 总消费时长       | 单次费用     |
-| -------- | ----------- | ------- | ----------- | -------- |
-| 9月1-2日   | 0.03-0.04小时 | 14-20条  | 0.37-0.76小时 | ¥1-3     |
-| **9月4日** | **0.57小时**  | **42条** | **24.05小时** | **¥3.5** |
-| **9月5日** | **0.58小时**  | **32条** | **18.71小时** | **¥3.5** |
-| 9月6日后    | 0.02小时      | 12条     | 0.20小时      | ¥0.7     |
-
-**关键发现**：
-
-* GP集群从短时查询模式变为长时间运行模式
-* 每小时消费时长增加**15倍**（0.04 → 0.57小时）
-* 接近满1小时计费，说明集群持续运行
-
-### 第三步：精确责任方定位
-
-**用户继续询问**：
-
-```
-看下是哪个实例那个工作空间的集群
-```
-
-**MCP Server多维度分析**：
-
-1. **实例和工作空间费用分布**
-
-   ```sql
-   SELECT 
-       instance_id,
-       workspace_name,
-       sku_name,
-       sum(total_after_discount) as total_cost
-   FROM sys.information_schema.instance_usage 
-   WHERE date(measurement_start) IN ('2025-09-04', '2025-09-05')
-     AND sku_category = 'compute'
-   GROUP BY instance_id, workspace_name, sku_name
-   ORDER BY total_cost DESC
-   ```
-
-**责任方分析结果**：
-
-| 实例ID       | 工作空间                         | 9月4日费用     | 9月5日费用     | 异常程度         |
-| ---------- | ---------------------------- | ---------- | ---------- | ------------ |
-| **270397** | **quick\_start**             | **¥83.48** | **¥64.77** | 🚨 **主要责任方** |
-| 270397     | lakehouse\_quick\_experience | ¥0.71      | ¥0.71      | ✅ 正常         |
-| 270397     | ns227206                     | ¥0.17      | ¥0.17      | ✅ 正常         |
-
-2. **具体集群使用详情**
-
-   ```sql
-   SELECT 
-       date(measurement_start) as usage_date,
-       hour(measurement_start) as usage_hour,
-       measurements_consumption,
-       amount
-   FROM sys.information_schema.instance_usage 
-   WHERE workspace_name = 'quick_start' 
-     AND sku_name = 'GP类型计算集群'
-     AND amount >
-
-**GP集群运行时间分析**：
-
-**9月4日异常模式**：
-
-* **00:00-23:59**：24小时持续运行
-* **每小时消费**：~1.00小时（几乎满小时计费）
-* **单小时费用**：¥3.5左右
-
-**9月5日异常模式**：
-
-* **00:00-18:59**：19小时持续运行
-* **费用模式**：同样接近满小时计费
-
-**关键发现**：
-
-* 问题锁定在 `quick_start` 工作空间的GP集群
-* 集群呈现24小时近乎不间断运行状态
-* **非**正常的短时查询模式
-
-### 第四步：根本原因追踪
-
-**MCP Server自动深入调查**：
-
-1. **作业历史分析**
-
-   <= '2025-09-06 23:59:59'
-   ```
-
-**正常期间作业特征**：
-
-* 查询执行时间：几秒到几分钟
-* 集群自动挂起：查询完成后快速释放
-* 费用模式：按实际使用时间计费
-
-## 问题根源深度解析
-
-### 技术层面分析
-
-**1. 动态表配置错误**
-
-```sql
--- 问题配置（推测）
-CREATE DYNAMIC TABLE mcp_test_daily_summary
-REFRESH_INTERVAL = '5 MINUTES'  -- ❌ 过于频繁
-AS SELECT ...
-```
-
-**2. 集群资源管理失效**
-
-* **正常模式**: 查询完成 → 集群空闲 → 自动挂起（几分钟内）
-* **异常模式**: 查询完成 → 5分钟后新查询 → 集群持续活跃 → 无法挂起
-
-**3. 费用计算逻辑**
-
-* **按小时计费**: GP集群按使用时长计费，¥3.5/小时
-* **最小计费单位**: 即使使用几分钟，活跃状态会累积计费时间
-* **累积效应**: 5分钟间隔刷新 → 24小时几乎满计费
-
-### 业务影响评估
-
-**1. 直接费用损失**
-
-* **异常期间**: 2天总费用¥152.42
-* **正常期间**: 2天预期费用¥2-12
-* **直接损失**: ¥140-150
-
-**2. 潜在风险**
-
-* **如未及时发现**: 每日额外费用¥80+
-* **月度影响**: 可能产生¥2400+额外费用
-* **资源浪费**: 集群资源未得到有效利用
-
-**3. 系统性问题**
-
-* **配置管理**: 动态表刷新策略缺乏合理性检查
-* **监控告警**: 费用异常未及时发现
-* **资源优化**: 集群自动管理策略需要优化
-
-## 解决方案与最佳实践
-
-### 立即修复措施
-
-**1. 动态表配置修正**
-
-```sql
--- 检查当前配置
-DESC DYNAMIC TABLE mcp_test_daily_summary;
-
--- 方案一：调整刷新间隔（推荐）
-ALTER DYNAMIC TABLE mcp_test_daily_summary 
-SET REFRESH_INTERVAL = '1 HOUR';
-
--- 方案二：根据业务需求调整
-ALTER DYNAMIC TABLE mcp_test_daily_summary 
-SET REFRESH_INTERVAL = '4 HOURS';  -- 或其他合理间隔
-
--- 方案三：暂停动态表（紧急情况）
-ALTER DYNAMIC TABLE mcp_test_daily_summary SUSPEND;
-```
-
-**2. 集群配置优化**
-
-```sql
--- 检查集群自动挂起设置
-SHOW VIRTUAL_CLUSTERS;
-
--- 确保合理的自动挂起时间
-ALTER VIRTUAL_CLUSTER your_gp_cluster 
-SET AUTO_SUSPEND_IN_SECOND = 300;  -- 5分钟自动挂起
-```
-
-### 预防性措施
-
-**1. 监控和告警**
-
-```sql

-# CREATE ....CLONE
-
-> 【预览发布】本功能当前处于公开预览发布阶段。
-
-在 Lakehouse 中，克隆表操作创建了一个表的独立副本，该副本与原始表完全分离，互不影响。克隆表在创建时不占用额外的存储空间，因为它共享原始表的数据版本。但是，如果原始表数据发生变化并影响到克隆表中的数据，克隆表将需要为这些变化支付存储费用。克隆表具有与普通表相似的功能，包括查询、复制和删除等操作。Lakehouse 支持克隆普通表和动态表，并且允许创建克隆的克隆，即克隆一个已经是克隆的表。
-
-## 克隆表注意事项
-
-* 克隆操作不会复制原始表的权限，新克隆的表将具有独立的权限设置。
-* 克隆操作不会复制用户设置的属性，包括生命周期和数据时间旅行保留周期。
-* 实时写入且未提交的数据不会被克隆。因此，在克隆完成后，刚刚写入的数据将无法在克隆表中找到。
-* 不支持克隆外部表。
-
-## 普通表克隆
-
-```SQL
-CREATE TABLE [ IF NOT EXISTS ] table_name CLONE <source_object_name> [TIMESTAMP AS OF timestamp_expression]
-```
-
-* 可以使用 `TIMESTAMP AS OF timestamp_expression` 来克隆动态表在指定时间点的版本。只要该时间点在\*\*[数据保留周期](TIMETRAVEL.md)\*\*内（`data_retention_days`）。
-  * `timestamp_expression` 可以是以下任意一项：
-    * `'2024-10-18T22:15:12.013Z'`，即可以强制转换为时间戳的字符串
-    * `cast('2024-10-18 13:36:32 ' as timestamp)`
-    * `'2024-10-18'`，即日期字符串
-    * `current_timestamp() - interval 12 hours`
-    * `date_sub(current_date(), 1)`
-    * 本身就是时间戳或可强制转换为时间戳的任何其他表达式
-
-```
-CREATE TABLE normal_table_clone_version CLONE normal_table_base TIMESTAMP AS OF '2024-10-12 19:23:52.329';
-```
-
-## 动态表克隆
-
-```SQL
-CREATE DYNAMIC TABLE dt_name
- [
-    refreshOption ::=
-    REFRESH [START WITH timestamp_expr] [interval_time] VCLUSTER vcname   
- ]
-  CLONE <source_dynamic_table> [TIMESTAMP AS OF timestamp_expression]
-```
-
-* 克隆出的动态表默认暂停刷新，可以使用 `ALTER DYNAMIC TABLE table_name RESUME;` 来启动刷新任务。
-* `DYNAMIC TABLE dt_name`: 要创建的动态表的名称，`dt_name` 是一个占位符，您需要替换为实际的表名。
-* `REFRESH`：指定表的刷新选项。克隆动态表时可以指定刷新选项：
-  * 如果指定了刷新选项，则使用克隆表的刷新策略。
-  * 如果未指定刷新选项，则使用默认的刷新策略。
-* `START WITH timestamp_expr`: 可选子句，指定表开始刷新的时间点，`timestamp_expr` 是一个时间戳表达式。
-* `interval_time`: 指定刷新间隔的时间单位，这是一个 `INTERVAL` 类型，可以是以下任意一项：
-  * INTERVAL 1 year
-  * INTERVAL 2 month
-  * INTERVAL 3 day
-  * INTERVAL 4 hour
-  * INTERVAL 5 minute
-  * INTERVAL 30 second
-* `VCLUSTER vcname`: 指定计算集群的名称，`vcname` 是计算集群的实际名称。
-* `CLONE <source_dynamic_table>`: 从现有的动态表 `<source_dynamic_table>` 克隆。
-* `TIMESTAMP AS OF timestamp_expression`: 克隆动态表在指定时间点的版本，`timestamp_expression` 可以是多种时间戳表达式之一。只要该时间点在[数据保留周期](TIMETRAVEL.md)内（`data_retention_days`）。
-  * `timestamp_expression` 可以是以下任意一项：
-    * `'2024-10-18T22:15:12.013Z'`，即可以强制转换为时间戳的字符串
-    * `cast('2024-10-18 13:36:32 ' as timestamp)`
-    * `'2024-10-18'`，即日期字符串
-    * `current_timestamp() - interval 12 hours`
-    * `date_sub(current_date(), 1)`
-    * 本身就是时间戳或可强制转换为时间戳的任何其他表达式
-
-## 权限要求
-
-* 需要有当前 schema 下的 `CREATE TABLE` 权限来创建克隆表。
-* 需要有对原始表的 `SELECT` 权限。
-
-## 克隆表案例
-
-### 克隆普通表
-
-```SQL
--- 创建普通表
-CREATE TABLE normal_table_base (id BIGINT, col STRING);
-
--- 克隆普通表
-CREATE TABLE normal_table_clone CLONE normal_table_base;
-
--- 指定基表的版本克隆
-CREATE TABLE normal_table_clone_version CLONE normal_table_base TIMESTAMP AS OF '2024-10-12 19:23:52.329';
-```
-
-### 克隆动态表
-
-```SQL
--- 创建动态表
-CREATE DYNAMIC TABLE dt_table_base
-REFRESH INTERVAL 1 MINUTE
-VCLUSTER DEFAULT
-AS SELECT * FROM normal_table_base;
-
--- 克隆动态表
-CREATE DYNAMIC TABLE dt_table_clone CLONE dt_table_base;
-
--- 克隆时指定刷新间隔和计算集群
-CREATE DYNAMIC TABLE dt_table_clone_refresh
-REFRESH INTERVAL 2 MINUTE
-VCLUSTER DEFAULT
-CLONE dt_table_base;
-
--- 克隆时指定动态表的版本
-CREATE DYNAMIC TABLE dt_table_clone_version
-CLONE dt_table_base TIMESTAMP AS OF '2024-10-12 20:25:32.247';

-# 分桶键（Clustered Key）和排序键（Sorted Key）
-
-在大数据存储与分析领域，数据的组织方式对查询性能和存储效率具有重要影响。本文将详细介绍分桶键（Clustered Key）和排序键（Sorted Key）的概念、使用方法以及实际应用示例，帮助您更好地优化数据组织结构。
-
-## 分桶键（Clustered Key）
-
-分桶键是表数据分布的核心。通过指定分桶键，Lakehouse会根据这些键对数据进行Hash运算，并将数据分散到不同的数据分桶（buckets）中。这种分散有助于避免数据倾斜和热点问题，同时提高并行处理能力。
-
-### 选择分桶键的准则
-
-- 选择取值范围广、重复值少的列作为分桶键，以实现数据的均匀分布。
-- 在进行`JOIN`操作时，如果连接的键与分桶键一致，可以显著提高性能。
-- 适用于数据量大的场景，推荐的数据分桶大小约为128MB到1GB，具体取决于数据的压缩率和访问模式。
-- 如果没有指定分桶键，则默认使用256个分桶。
-
-### 注意事项
-
-- 避免指定过小的分桶数量，以免产生大量小文件，影响元数据管理和I/O操作效率。
-- 过多的小文件会导致数据局部性差，增加任务调度开销，降低处理效率。
-
-## 排序键（Sorted Key）
-
-排序键用于指定数据文件内字段的排序方式。对于需要按特定字段排序或进行范围查询的场景，预先将数据按排序键组织可以大幅提高查询性能。
-
-### 使用排序键的注意事项
-
-- 可以为排序键指定升序（ASC）或降序（DESC）。
-- 虽然排序键可以提高查询性能，但在对大量数据进行插入时，维护排序顺序可能会消耗较多计算和I/O资源。
-
-## 实际应用示例
-
-### 示例1：创建表并指定分桶键与排序键
-
-```sql
-CREATE TABLE sales_data (
-    sale_id INT,
-    product_id INT,
-    quantity_sold INT,
-    sale_date DATE,
-    ...
-) CLUSTERED BY (product_id)
-SORTED BY (sale_date DESC)
-INTO 50 BUCKETS;
-```
-
-在这个示例中，创建了一个名为`sales_data`的表，数据将根据`product_id`列的哈希值被分散到50个分桶中。同时，分桶内的数据将按照`sale_date`列的降序进行排序。
-
-### 示例2：优化数据仓库的查询性能
-
-假设您正在处理一个包含大量交易记录的数据仓库，可以通过以下方式优化查询性能：
-
-```sql
-CREATE TABLE transaction_records (
-    transaction_id INT,
-    customer_id INT,
-    transaction_date DATE,
-    amount DECIMAL(10,2),
-    ...
-) CLUSTERED BY (customer_id)
-SORTED BY (transaction_date ASC)
-INTO 128 BUCKETS;
-```
-
-在这个示例中，`transaction_records`表根据`customer_id`进行分桶，分桶内的数据按照`transaction_date`进行排序。这样的设计有助于提高按客户查询交易记录的效率。
-
-## 结语
-
-合理使用分桶键和排序键，可以有效优化数据的物理存储结构，提高查询性能，尤其是在处理大规模数据集时。这种方法特别适用于数据仓库和大数据分析场景，可以显著提升数据处理的效率。希望本文能帮助您更好地理解和应用分桶键与排序键，从而优化您的数据组织方式。

-在大数据存储与分析领域，数据的组织方式对于查询性能和存储效率具有重要影响。本文将详细介绍分桶键（Clustered Key）和排序键（Sorted Key）的概念、使用方法以及实际应用示例，帮助您更好地优化数据组织结构。
-
-## 分桶键（Clustered Key）
-
-分桶键是表数据分布的核心，通过指定列的Hash Key，Lakehouse会根据这些键对数据进行Hash运算，并将数据分散到不同的数据分桶（buckets）中。这种分散有助于避免数据倾斜和热点问题，同时提高并行处理的能力。
-
-### 选择分桶键的准则
-
-- 选择取值范围广、重复值少的列作为分桶键，以实现数据的均匀分布。
-- 在进行`JOIN`操作时，如果连接的键与分桶键一致，可以显著提高性能。
-- 适用于数据量大的场景，推荐的数据分桶大小约为128MB到1GB，具体取决于数据的压缩率和访问模式。
-- 如果没有指定分桶键，则默认使用256个分桶。
-
-### 注意事项
-
-- 避免指定过小的分桶键数量，以免产生大量小文件，影响元数据管理和I/O操作效率。
-- 过多的小文件会导致数据局部性差，增加任务调度开销，降低处理效率。
-
-## 排序键（Sorted Key）
-
-排序键用于定义文件内数据的排序方式。对于需要按排序键进行排序的查询，预先将数据按排序键组织可以提高查询性能。
-
-### 使用排序键的注意事项
-
-- 可以为排序键指定升序（ASC）或降序（DESC）。
-- 虽然排序键可以提高查询性能，但对大量数据进行插入时排序可能会消耗较多资源。
-
-## 实际应用示例
-
-### 示例1：创建表并指定分桶键与排序键
-
-```sql
-CREATE TABLE sales_data (
-    sale_id INT,
-    product_id INT,
-    quantity_sold INT,
-    sale_date DATE,
-    ...
-) CLUSTERED BY (product_id)
-SORTED BY (sale_date DESC)
-INTO 50 BUCKETS;
-```
-
-在这个示例中，创建了一个名为`sales_data`的表，数据将根据`product_id`列的Hash值被分散到50个分桶中。同时，分桶内的数据将按照`sale_date`列的降序进行排序。
-
-### 示例2：优化数据仓库的查询性能
-
-假设您正在处理一个包含大量交易记录的数据仓库，可以通过以下方式优化查询性能：
-
-```sql
-CREATE TABLE transaction_records (
-    transaction_id INT,
-    customer_id INT,
-    transaction_date DATE,
-    amount DECIMAL(10,2),
-    ...
-) CLUSTERED BY (customer_id)
-SORTED BY (transaction_date ASC)
-INTO 128 BUCKETS;
-```
-
-在这个示例中，`transaction_records`表根据`customer_id`进行分桶，分桶内的数据按照`transaction_date`进行排序。这样的设计有助于提高按客户查询交易记录的效率。

-# 组合任务
-
-组合任务是一种特殊的任务类型，它支持将多个周期任务（例如离线同步、SQL 任务）封装为独立单元，以实现**统一调度配置、参数管理和运维操作**，并且能够与其他普通节点建立依赖关系。本任务类型适用于需要批量管理任务流程、统一控制调度周期的业务场景（如增量计算、跨任务协同）。组合任务与[任务组](task_group.md)功能进行对比，两者存在以下核心区别：
-* 任务组属于逻辑管理概念，可将多种任务置于一个组内进行统一展示与编排。组合任务是一种任务类型的实体，与普通的 SQL 任务处于同等地位，可在任务组中添加组合任务作为其元素之一。
-* 从外部看，组合任务是一个整体，但内部会包含一到多个子任务节点（这些子任务可以是 SQL 任务、离线同步任务等各种周期调度任务）。
-* 组合任务支持统一设定调度时间，其内部所有子任务节点依据该调度时间进行同频调度。这尤其适用于对所有任务节点的数据新鲜度有相同要求的数据处理链路。任务组上不支持设定调度定时属性。
-
-## 快速上手：创建组合任务
-
-组合任务的创建操作，整体上和普通周期 SQL 任务等非常类似。
-
-### 创建入口
-
-支持通过以下路径新建组合任务：
-
-* 任务开发：任务Tab → 新建任务 → 选择“组合任务”
-
-  ![](.topwrite/assets/image_1752130018729.png =420)
-
-* 任务组详情页：任务组内 → 添加新任务 → 选择“组合任务”；
-  
-  ![](.topwrite/assets/image_1752130033606.png =680)
-
-* 工作区：顶部导航栏 → 新建任务 → 选择“组合任务”。
-  
-  ![](.topwrite/assets/image_1752130048252.png =680)
-
-### 基础信息填写
-
-在创建组合任务的弹框中，和其他普通 SQL 任务一样，填写需要的信息：
-
-* 任务名称：必填。
-* 文件夹：任务要放入的文件夹（必填）。
-* 任务组：选择是否放入任务组，如需放入则选定具体的任务组名称（可选）。
-
-  ![](.topwrite/assets/image_1752130064673.png =680)
-
-## 核心功能操作指南
-
-### 子任务管理（画布模式）
-
-组合任务目前通过**画布**（DAG 图）来展示子任务节点，并支持以下操作：
-![](.topwrite/assets/image_1752130101512.png =680)
-
-#### 添加子任务
-
-* **入口**：画布工具栏 → 「新建子任务」→ 选择任务类型（仅支持周期任务：离线同步、SQL等；**不支持实时任务**）。通过单击任务类型或拖拽的方式，可将子任务添加到组合任务中。
-
-  ![](.topwrite/assets/image_1752130110716.png =360)
-
-* **默认状态**：新增的子任务，默认无依赖，需手动调整依赖关系（通过页面上连线或在子任务详情进行配置）。
-
-#### 编辑子任务
-
-* **方式**：
-  * 在添加子任务节点时，会默认进入子任务的详情页，便于编写代码和配置调度信息。
-  * 双击子任务 → 进入普通节点编辑页（复用现有编辑功能）；
-
-* **限制**：为了确保组合任务提交后运行正常，子任务不支持独立保存为半成品，需填写所有必填属性（如代码、集群、调度属性）后才能保存。在退出子任务编辑前，请确保这些信息完整且已正确保存。
-
-#### 依赖编排
-
-* **子任务中配置**：在子任务上，点击「调度」→ 在「调度依赖」中设定它依赖的上游子任务。
-* **画布上连线**：在组合任务的DAG画布上，选中源节点 → 拖拽连线至目标节点 → 建立“上游→下游”依赖。也可以通过操作连线来删除依赖关系。
-
-#### 画布工具
-
-* **自动排版**：工具栏 → 「自动布局」→ 按依赖关系优化DAG展示；
-* **缩放/刷新**：工具栏 → 「+/-」调整画布大小，或「刷新」重置视图。
-
-### 调度配置（全局与局部结合）
-
-组合任务的调度策略通过**全局配置**（组合任务层级）与**局部配置**（子任务层级）协同管理。整体思路是：子任务默认继承组合任务的全局配置，也支持在局部单独配置；若局部已配置，则以局部配置为准。关键配置项如下表：
-
-| 配置项   | 全局配置（组合任务）              | 局部配置（子任务）                    |
-| ----- | ----------------------- | ---------------------------- |
-| 调度时间  | 必配，支持Cron表达式（子任务不可独立设置） | 无（子任务遵循组合任务全局设定的调度时间、同频调度运行） |
-| 实例重跑  | 全局设置（重跑次数、间隔），子任务默认继承   | 可选覆盖全局设置（仅支持SQL等特定任务类型）      |
-| 任务优先级 | 全局设置（默认值）               | 可选单独设置（覆盖全局，仅SQL节点支持）        |
-| 自依赖   | 全局设置（控制组合任务周期依赖）        | 无（子任务自依赖通过组合任务全局自依赖间接实现）     |
-
-**示例**：若组合任务全局设置为“重跑次数 3 次，间隔 5 分钟”，某子任务单独配置为“重跑次数 5 次”，则该子任务实际使用“重跑 5 次，间隔 5 分钟”。

-
-![](.topwrite/assets/image_1752130133390.png =680)
-
-### 参数管理（组合任务→子任务传递）
-
-#### 定义参数
-
-* **入口**：组合任务详情页 → 点击「参数」→ 在弹框中新增参数（如`composite_task_param`）：
-
-  ![](.topwrite/assets/image_1752130143435.png =680)
-
-  ![](.topwrite/assets/image_1752130151838.png =680)
-
-* **作用域**：仅当前组合任务内部有效，不同组合任务之间参数隔离。
-
-#### 引用参数
-
-在子任务的参数配置中，若参数名称与组合任务定义的参数名称相同，在参数取值处会自动识别并提示选择参数的取值来源。若要使用组合任务全局定义的参数，在取值来源处选择“组合任务”；否则，可选择“任务”。
-
-![](.topwrite/assets/image_1752130161305.png =680)
-
-在子任务的代码中，支持通过`${参数名}`引用参数。**示例**（SQL子任务）：
-
-```
-SELECT * FROM user_log WHERE dt = '${composite_task_param}'  
-```
-
-## 高级操作：保存与提交
-
-### 保存组合任务
-
-* 组合任务当前不支持全局统一保存所有子任务节点。请逐一保存每个子任务，确保其代码、调度配置等信息已保存。之后，再提交组合任务。
-
-### 提交组合任务
-
-* **作用**：支持将组合任务及内部所有子任务提交到生产环境周期调度运行，会生成对应的“提交版本”。
-
-* **操作入口**：组合任务详情页 → 「提交」。
-
-  ![](.topwrite/assets/image_1752130174992.png =680)
-
-## 运维与监控
-
-### 组合任务的运维
-
-组合任务在运维中心会与其他周期任务一并在列表中展示，并支持类似的操作，如暂停、补数据、下线等。
-
-![](.topwrite/assets/image_1752130184652.png =680)
-
-| 操作     | 说明                                                                 |
-| ------ | ------------------------------------------------------------------ |
-| 暂停/恢复 | 暂停后，组合任务及子任务停止调度；恢复后，按当前配置继续执行。                             |
-| 补数据    | 选择时间范围 → 组合任务整体按调度规则生成补数据实例（包含所有子任务实例）。                        |
-| 下线     | 下线后任务不再调度。需检查是否存在下游依赖（若存在下游依赖，则无法直接下线，需使用“下线（含下游）”功能）。 |
-
-### 组合任务实例的运维
-
-在实例运维 Tab 页，可以查看到组合任务的实例，与其他周期任务实例并列，并支持重跑、置成功/置失败等操作，如下图所示：
-
-![](.topwrite/assets/image_1752130199325.png =680)
-
-#### 状态查看
-
-* **整体状态**：组合任务实例状态由子任务状态综合判定，具备以下状态：未运行（所有子任务未运行）、运行中（任一子任务运行中）、运行成功（所有子任务成功）、运行失败（至少一个子任务失败）。
-* **下钻查看**：点击实例ID → 进入子任务实例DAG页，查看各子任务运行详情（含日志、状态）。
-
-#### 实例操作
-
-| 操作        | 在哪些状态下支持       | 行为说明                                                                 |
-| --------- | -------------- | ---------------------------------------------------------------------- |
-| 重跑        | 任意终态（失败/成功）    | 整体重跑组合任务，子任务按各自重跑规则生成新实例（不支持选择部分子任务）。                                 |
-| 置成功/置失败 | 未运行/终态         | 组合任务及所有子任务实例状态强制变更为成功/失败。                                            |
-| 终止        | 运行中            | 终止所有运行中/未运行的子任务实例，状态置为失败。                                              |
-
-### 组合任务的监控告警
-
-在监控告警中，组合任务会被归入周期调度任务这一大类。先前的“任务实例运行失败”、“周期任务实例完成时间”等监控项，对其也同样生效。可以像配置普通SQL周期任务一样，配置监控规则来对其运行状态和耗时等进行监控。
-
-![](.topwrite/assets/image_1752131374833.png =680)
-
-### 组合任务触发质量规则校验
-
-在配置数据质量规则时，于规则运行触发方式中，可选择组合任务作为调度触发对象，如下图所示。可以选择具体的子任务来触发；若“子任务”留空，则会在组合任务整体运行完成后触发。
-
-![](.topwrite/assets/image_1752131279717.png =680)
-
-## 注意事项
-
-1. **类型限制**：组合任务的子任务，仅支持周期任务（离线同步、SQL等），实时任务（多表实时同步、Continuous Job等）不可添加。
-2. **参数作用域**：组合任务参数仅内部可见，不能被其他组合任务使用。跨组合任务共享参数，需通过任务组参数等来承接。
-3. **版本管理**：组合任务仅支持“提交版本”（无保存版本），暂不支持版本回滚。
-4. **任务依赖**：在任务组内，组合任务作为整体存在，不可单独添加任务组内部的子任务，且依赖关系为组合任务整体与其他任务的依赖。组合任务的内部子任务不能依赖任务组内其他任务，也不能被任务组内其他任务依赖。

-## 测试数据生成
-
-本指南会为滑雪胜地的顾客生成虚构的缆车票等数据。
-
-您也许有自己想生成的数据，可随意修改数据生成器、表格和代码，让其更符合您的用例。
-
-本指南中介绍的大多数摄取方式都会用到数据，所以最好运行一次数据生成，然后在不同的摄取模式中重复使用生成的数据。
-
-在您的电脑上通过VS Code为这个项目创建一个目录，再添加一个叫 data\_generator.py 的文件。这个代码会以要创建的票数为参数，输出每行一张缆车票（记录）的 json 数据。本指南里的其他文件可以放在同一个目录中。
-
-你也可以直接[下载本文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/data_generator.py)。

-## Postgres和Kafka环境设置
-
-本指南使用Postgres作为数据库数据源。你可以使用已有的Postgres数据库。主要后续的数据库网络地址、数据库名称、Schema名称、用户名密码等保持一致即可。
-
-### 启动数据库实例
-
-在开始此步骤之前，请确保已为[Mac](https://docs.docker.com/desktop/install/mac-install/)、[Windows](https://docs.docker.com/desktop/install/windows-install/)或[Linux](https://docs.docker.com/desktop/install/linux/)安装了 Docker Desktop 。确保您的机器上已安装[Docker Compose 。](https://docs.docker.com/compose/install/)
-
-1. 要使用 Docker 启动 PostgreSQL 数据库，您需要创建一个名为docker-compose.yaml的文件。此文件将包含 PostgreSQL 数据库的配置。如果您有另一个容器客户端，请启动容器并使用下面的 PostgreSQL 映像。
-2. 打开您选择的 IDE（比如VS Code），通过复制并粘贴以下内容来复制并粘贴此文件（你也可以直接[下载本文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/data_generator.pyhttps://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/config/docker-compose.yaml)。）：
-
-```YAML
-services:
-  postgres:
-    image: "postgres:17"
-    container_name: "postgres17"
-    environment:
-      POSTGRES_DB: 'postgres'
-      POSTGRES_USER: 'postgres'
-      POSTGRES_PASSWORD: 'postgres'
-    ports:
-      - "5432:5432"
-    command:
-      - "postgres"
-      - "-c"
-      - "wal_level=logical"
-    volumes:
-      - ./postgres-data:/var/lib/postgresql/data
-  kafka:
-    image: 'bitnami/kafka:latest'
-    container_name: kafka
-    ports:
-      - "9093:9093"
-    expose:
-      - "9093"
-    environment:
-      - KAFKA_CREATE_TOPICS="clickzettalakehouserealtimeingest:1:1"
-      - KAFKA_CFG_AUTO_CREATE_TOPICS_ENABLE=true
-      - KAFKA_CFG_NODE_ID=0
-      - KAFKA_CFG_PROCESS_ROLES=controller,broker
-      - KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CLIENT:PLAINTEXT,EXTERNAL:PLAINTEXT,CONTROLLER:PLAINTEXT
-      - KAFKA_CFG_LISTENERS=CLIENT://:9092,EXTERNAL://:9093,CONTROLLER://:9094
-      - KAFKA_CFG_ADVERTISED_LISTENERS=CLIENT://kafka:9092,EXTERNAL://localhost:9093
-      - KAFKA_INTER_BROKER_LISTENER_NAME=CLIENT
-      - ALLOW_PLAINTEXT_LISTENER=yes
-      - KAFKA_CFG_CONTROLLER_QUORUM_VOTERS=0@localhost:9094
-      - KAFKA_CFG_CONTROLLER_LISTENER_NAMES=CONTROLLER
-    volumes:
-      - ./bitnami/kafka:/bitnami/kafka
-```
-
-3. 打开终端并导航到docker-compose.yaml文件所在的目录。运行以下命令启动 PostgreSQL 数据库：
-
-```Shell
-docker-compose up -d
-```
-
-### 创建Kafka Topic
-
-进入 Kafka 容器：
-
-bash
-
-```
-docker exec -it kafka /bin/bash
-```
-
-手动创建主题：
-
-bash
-
-```
-kafka-topics.sh --create --topic clickzetta_lakehouse_realtime_ingest --bootstrap-server localhost:9092 --partitions 1 --replication-factor 1
-```
-
-然后再次列出主题以确认创建是否成功：
-
-bash
-
-```
-kafka-topics.sh --list --bootstrap-server localhost:9092
-```
-
-如果主题成功创建，你应该会看到 `clickzetta_lakehouse_realtime_ingest` 列表中的主题。
-
-### 连接数据库
-
-要使用 Visual Studio Code 或 DBV/DBGrid/PyCharm 或您选择用于数据库连接的任何 IDE 连接到预配置的数据库，请使用提供的凭据执行以下步骤：
-
-1. 打开您选择的工具以连接 PostgreSQL 数据库
-
-   1. 对于 VSCode，你可以使用[PostgreSQL 扩展](https://marketplace.visualstudio.com/items?itemName=cweijan.vscode-postgresql-client2)
-   2. 对于 PyCharm，您可以使用[数据库工具和 SQL 插件](https://www.jetbrains.com/help/pycharm/database-tool-window.html)
-
-2. 单击`+`符号或类似符号以添加数据源
-
-3. 使用这些连接参数：
-
-   1. 用户：`postgres`
-   2. 密码：`postgres`
-   3. 数据库：`postgres`
-   4. 网址：`jdbc:postgresql://localhost:5432/`
-
-4. 测试连接并保存
-
-5. 为了能让云器Lakehouse Studio通过公网能够访问到Postgres数据库，务必给Posrgres数据库做公网NAT映射。
-
-### 加载数据
-
-1. 在 PostgreSQL 中运行以下postgres脚本来创建模式和表(你也可以直接[下载本文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/posgtres_ddl.sql)。）：
-
-```SQL

-
-```
-
-2. 将以下代码Copy进Python文件然后运行
-3. 在电脑上打开VS Code，创建一个名为 import\_csv\_into\_pg.py 的文件，并将以下代码复制到import\_csv\_into\_pg.py文件中。lift\_tickets\_data.csv文件为在“测试数据生成”步骤生成的gz文件解压后的文件。(你也可以直接[下载本文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/import_csv_into_pg.py)。）
-
-```Python
-import psycopg2
-import os
-def load_csv_to_postgres(csv_file, table_name):
-    with open(csv_file, 'r') as f:
-        cur.copy_expert(f"COPY {table_name} FROM STDIN WITH CSV HEADER DELIMITER ','", f)
-    conn.commit()
-# 数据库连接信息
-conn = psycopg2.connect(
-    dbname="postgres",
-    user="postgres",
-    password="postgres",
-    host="localhost",
-    port="5432"
-)
-cur = conn.cursor()
-# 设置 search_path 
-cur.execute("SET search_path TO ingest_demo;")
-
-# Clear all data from the lift_tickets_data table 
-# cur.execute("TRUNCATE lift_tickets_data;")
-
-
-# 定义CSV文件所在目录
-csv_directory = 'data'
-
-# 按表的依赖关系排列的CSV文件列表
-csv_files = [
-    "lift_tickets_data.csv",         # 首先导入被依赖的表
-    "weather_data.csv",
-    "lift_usage_data.csv",
-    "feedback_data.csv",
-    "incident_reports.csv",
-    "accommodation_data.csv"
-]
-
-# 遍历文件列表并加载到对应的表中
-for filename in csv_files:
-    csv_file = os.path.join(csv_directory, filename)
-    table_name = os.path.splitext(filename)[0]  # 文件名去掉扩展名作为表名
-    print(f"Loading {csv_file} into table {table_name}...")
-    load_csv_to_postgres(csv_file, table_name)
-    print(f"Loaded {csv_file} into table {table_name} successfully!")
-
-# Execute the SELECT query to count the rows in the table 
-cur.execute("SELECT count(*) FROM lift_tickets_data;")
-count = cur.fetchone()[0] 
-# Print the result 
-print(f"Total number of records in lift_tickets_data: {count}")
-# 关闭游标和连接
-cur.close()
-conn.close()
-```
-
-在VS Code里新建一个“终端”，并运行如下命令激活在“环境设置”步骤创建的Python环境。如果已在cz-ingest-examples环境里，请跳过。
-
-```Shell
-conda activate cz-ingest-examples
-```
-
-然后在同一终端里运行如下命令：
-
-```Shell
-python import_csv_into_pg.py
-```
-
-输出显示如下，则表示数据导入成功：
-
-```Markdown
-Total number of records in lift_tickets_data: 100000
-```

-
-## 数据入仓：通过JavaSDK批量和实时加载数据
-
-#### 概述
-
-云器Lakehouse提供了[JAVA SDK](java_reference/java-sdk-summary.md)，可在流行的IDE（如VS Code）中通过Java和SQL编程的方式，将数据加载到云器Lakehouse的表里。
-
-#### 使用场景
-
-这种方式可以方便地批量加载数据，适合在Java编程环境中进行大量数据的批量导入和实时写入，因为云器Lakehouse针对大批量数据写入进行了更多优化。
-
-#### 实现步骤
-
-##### 下载代码
-
-从[Github仓库里](https://github.com/yunqiqiliang/clickzetta_quickstart/tree/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta)下载本指南的代码到本地（如果已下载请忽略）。
-
-将项目目录添加到VS Code的工作区中。
-
-:-: ![](.topwrite/assets/image_1736229919125.png =512)
-
-##### 修改参数

-# 将数据导入云器 Lakehouse 的完整指南
-
-## 数据入仓：使用Lakehouse Studio实时同步导入Kafka数据
-
-#### 概述
-
-#### 使用场景
-
-已有 Kafka 数据源，对数据同步的实时性要求高，期望能实时同步到 Lakehouse 的表中，实现端到端秒级延迟。
-
-#### 实现步骤
-
-导航到 开发 -> 任务，点击“+”，选择“实时同步”，新建一个“实时同步”作业。
-
-:-: ![](.topwrite/assets/image_1736319394961.png =740)
-
-主要配置如下：
-
-:-: ![](.topwrite/assets/image_1736319702232.png =740)
-
-^
-
-在左侧选择源端 Kafka 数据源时，请配置正确的 `mode`、`groupId` 和 `codec`。其中请特别注意，`groupId` 尽量不要在多个实时同步任务中复用，以避免相互干扰、同时消费数据导致目标数据丢失或不完整的情况。
-
-^
-
-然后在右侧选择Lakehouse目标端，选择已有的数据表，或者新建数据表（推荐使用）：target\_table\_from\_kafka。
-
-在“新建数据表”SQL代码里，将表名改为“target\_table\_from\_kafka”。
-
-:-: ![](.topwrite/assets/image_1736321482644.png =740)
-
-^
-
-在“字段映射配置”区域，系统会默认使用 Kafka Topic 的内置字段进行数据字段映射。如果 Topic 内的消息格式为 JSON，您还可以通过新增计算列的方式，使用 JSONPath 规则解析 `value` 字段中的内容。例如，通过下图所示的 `[__value__].[accountId]` 来提取源端 Topic 中 `__value__` 字段内的 `accountId`，并写入到目标端的 `__value__` 字段中。
-
-:-: ![](.topwrite/assets/image_1736322127793.png =740)
-
-^
-
-在“同步规则配置”中，设定同步的最大并发数。增大并发数可以提升数据消费速度。
-
-^
-
-检查字段映射符合预期后，在配置中设定“集群”等必填信息，点击“确定”，然后点击“保存”以保存任务配置。
-
-:-: ![](.topwrite/assets/image_1736322224165.png =740)
-
-实时同步任务当前不支持直接运行测试，需要提交发布后，检查运行结果是否正常。
-
-:-: ![](.topwrite/assets/image_1736322037109.png =740)
-
-#### 下一步建议
-
-* 在运维中心启动实时同步任务，观察任务运行指标并验证数据同步结果是否正常。
-
-  :-: ![](.topwrite/assets/image_1736322337162.png =740)
-
-* 第一次启动时选择“无状态启动”的方式即可。
-
-  :-: ![](.topwrite/assets/image_1736322414065.png =740)
-
-* 正常启动后，可以看到以下监控指标，表示同步任务运行正常。
-
-  :-: ![](.topwrite/assets/image_1736322603085.png =740)
-
-* 抽查目标表中的数据，与源端数据进行校验核对，确认是否符合预期。

-# 将数据导入云器Lakehouse的完整指南
-
-## 数据入仓：通过云器Lakehouse Studio 加载本地文件
-
-#### 概述
-
-您将使用[云器Lakehouse Studio](https://accounts.clickzetta.com/)来基于WEB界面操作、以无代码的方式来加载本地数据到云器Lakehouse的表中。
-
-#### 使用场景
-
-适合较小（不大于2GB）的本地文件（CSV、TXT、Parquet、AVRO、ORC）直接上传到云器Lakehouse的表中，无需编程实现，实现方式最简单。
-
-#### 实现步骤
-
-##### 上传文件
-
-导航到数据->数据目录，单击“上传数据”，导入本地文件（测试数据生成章节生成的CSV文件）到表中。
-
-:-: ![](.topwrite/assets/image_1736146842294.png =519)
-
-##### 导入数据
-
-点击“上传数据”：
-
-* 测试数据生成章节生成的测试数据
-* 云器Lakehouse设置章节创建的Schema
-* 选择新建表，表名为：lift\_tuckets\_import\_by\_studio\_web
-* 云器Lakehouse设置章节创建的虚拟计算集群
-
-:-: ![](.topwrite/assets/image_1736146857816.png =513)
-
-点击“下一步”后，检查上传数据自动设置项是否正确，如果数据预览符合预期，则自动设置正确，点击“确认”即可完成数据上传。
-
-:-: ![](.topwrite/assets/image_1736146867287.png =516)
-
-##### 结果校验
-
-进入“数据”查看导入状态和数据：
-
-可以看到导入数据的结果里，写入行数为“100,000”，这个在“测试数据生成”步骤生成的数量一致。
-
-:-: ![](.topwrite/assets/image_1736146881028.png =523)
-
-可以进一步“预览数据”，确认数据加载成功：
-
-:-: ![](.topwrite/assets/image_1736146888569.png =518)
-
-至此，我们通过云器Lakehouse Studio 加载本地文件到表中。
-
-:-: ![](.topwrite/assets/image_1736146899159.png =515)
-
-#### 下一步建议
-
-* 继续加载数据到同一张表中或者其它表中。通过在上个页面的“上传”，可以上传更多数据到同一张表中。
-* 通过云器Lakehouse自带的DataGPT进行可视化数据探索、以问答方式进行数据分析。
-* 在云器Lakehouse Studio的IDE里开发SQL任务，进一步清洗和转换数据，分析数据。

-# 将数据导入云器Lakehouse的完整指南
-
-## 数据入仓：通过云器Lakehouse Studio 批量加载（公网连接）
-
-#### 概述
-
-#### 使用场景
-
-已有数据源（包括数据库、数据仓库）具备公网可访问的地址（比如做了公网NAT映射），单表数据量大，且要求同步成本低，对数据新鲜度要求低（往往是小时级别甚至天级别）的情况下，将数据从数据源的表同步到Lakehouse的表中。
-
-#### 实现步骤
-
-导航到开发->任务，点击“+”，选择“离线同步”，新建一个“离线同步”作业。
-
-:-: ![](.topwrite/assets/image_1736147655855.png =464)
-
-其它参数配置如下：
-
-:-: ![](.topwrite/assets/image_1736147664609.png =470)
-
-然后选择新建数据表：lift_tickets_data_from_pg_batch。
-
-在"新建数据表"SQL代码里，将表名改为"lift_tickets_data_from_pg_batch"。
-
-:-: ![](.topwrite/assets/image_1736147671728.png =455)
-
-检查字段映射是否符合预期，然后测试运行同步任务：
-
-:-: ![](.topwrite/assets/image_1736147681157.png =459)
-
-检查测试结果：
-
-查看测试任务的日志，检查numWrite的数量和源表的数据行数一致。
-
-:-: ![](.topwrite/assets/image_1736147689681.png =469)
-
-#### 下一步建议
-
-* 配置where条件，设置每次运行需要同步的数据，而不是全量。一般是基于时间字段的过滤。
-
-* 配置调度参数并提交、运维，周期性同步数据。
-
-  * 如果是适合数据量小的维表数据，则无需设置where条件，将数据写入模式设置为"覆盖写入"，每次都进行全量覆盖。
-  * 如果是数据量大的事实表数据，需要设置where条件，将数据写入模式设置为“追加写入”，每次都进行增量追加写入，以降低每次的同步数据量和同步成本。避免每次都全量同步带来的高成本。
-
-* 离线同步任务作为数据ELT的数据抽取（E）和加载（L）的开始，可以进一步通过SQL任务对加载进数仓的数据进行清洗和转化（T）。

-#### 实现步骤
-
-##### 新建Python任务
-
-导航到开发->任务，单击“+”，新建一个Python任务。
-
-任务名：05\_通过Studio内置的Python节点从web加载文件入湖。
-
-:-: ![](.topwrite/assets/image_1736148972084.png =427)
-
-##### 开发Python任务代码
-
-将[如下代码](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/py_data_to_datalake_from_web_by_python_node.py)粘贴到新建Python任务的代码编辑器里：
-
-```Python
-import os,io
-import subprocess
-from datetime import datetime, timedelta
-import oss2
-
-# 阿里云OSS配置
-ACCESS_KEY_ID = '${ak}'
-ACCESS_KEY_SECRET = '${sk}'
-BUCKET_NAME = '你的bucketname'
-ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com'
-ROOT_PATH = f'{BUCKET_NAME}/ingest_demo/from_web'
-
-try:
-    # 构建wget命令
-    url = f"https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/data/lift_tickets_data.csv.gz"
-    cmd = ["wget", "-qO-", url]
-    print(f"wget cmd: {cmd}")
-
-    # 执行wget命令并捕获输出
-    wget_output = subprocess.check_output(cmd)
-    print(f"Wget file done...")
-
-    # 将输出转换为内存中的文件对象
-    file_obj = io.BytesIO(wget_output)
-except Exception as e:
-    print(f"An error occurred: {e}")
-    file_obj = None
-    raise
-
-if file_obj:
-    try:
-        # 初始化阿里云OSS
-        auth = oss2.Auth(ACCESS_KEY_ID, ACCESS_KEY_SECRET)
-        bucket = oss2.Bucket(auth, ENDPOINT, BUCKET_NAME)
-
-        # 上传文件到OSS
-        oss_path = f"{ROOT_PATH}/lift_tickets_data.csv.gz"
-        print(f"osspath: {oss_path}")
-        bucket.put_object(oss_path, file_obj)
-        print(f"Put file to oss done...")
-    except Exception as e:
-        print(f"An error occurred: {e}")
-    finally:
-        # 关闭内存中的文件对象
-        file_obj.close()
-```
-
-##### 给任务配置参数
-
-其中有两个参数：
-
-ACCESS\_KEY\_ID = '${ak}'ACCESS\_KEY\_SECRET = '${sk}'
-
-通过点击“调度”为参数填上默认值：
-
-:-: ![](.topwrite/assets/image_1736148983636.png =435)
-
-点击“加载代码中的参数”，并为参数填写对应的值：
-
-:-: ![](.topwrite/assets/image_1736148989712.png =431)
-
-##### 运行测试
-
-点击“运行”，执行Python代码。
-
-:-: ![](.topwrite/assets/image_1736148997078.png =427)
-
-##### 检查上传结果
-
-登录阿里云对象存储，查看上传的文件。
-
-:-: ![](.topwrite/assets/image_1736149004171.png =415)
-
-#### 下一步建议
-
-* 调度Python任务，实现周期性数据入湖。
-* 对加载到数据湖里的文件通过SQL进行数据湖分析。
-* 与其他任务形成完整的ELT工作流。

-# 将数据导入云器 Lakehouse 的完整指南
-
-## 数据入仓：通过云器 Lakehouse Studio 多表实时同步（CDC，公网连接）
-
-#### 概述
-
-#### 使用场景
-
-已有数据源（包括数据库、数据仓库）具备公网可访问的地址（比如做了公网 NAT 映射），需要多表同时同步，对数据新鲜度要求高（往往是分钟级别甚至秒级别），并且能够接受较高的同步成本的情况下，将数据从数据源的表同步到 Lakehouse 的表中。
-
-云器 Lakehouse Studio 多表实时同步支持多表合并，可以将结构相似的多个源表的数据合并到一张云器 Lakehouse 目标表中。
-
-#### 实现步骤
-
-##### 新建多表实时同步任务
-
-导航到 开发 -> 任务，点击“+”，选择“多表实时同步”，新建一个多表实时同步任务。
-
-:-: ![](.topwrite/assets/image_1736147975347.png =494)
-
-任务名：06\_multi\_table\_rt\_sync\_from\_pg
-
-##### 来源数据选择“PostgreSQL”
-
-:-: ![](.topwrite/assets/image_1736147983573.png =502)
-
-##### 选择同步对象
-
-云器 Lakehouse Studio 会自动同步源库结构供选择：
-
-:-: ![](.topwrite/assets/image_1736147992225.png =467)
-
-##### 数据库CDC配置
-
-创建一个 Slot
-
-:-: ![](.topwrite/assets/image_1736148001087.png =459)
-
-插件类型：pgoutput
-
-Slot名：slot\_for\_multi\_table\_ingest\_demo
-
-##### 目标配置
-
-规则表达式：multitable_sync_{SOURCE_TABLE}。给目标表加上前缀 multitable_sync_{SOURCE_TABLE}，以区分和其它方式同步进来的表。
-
-查看字段映射，确保所有字段都映射成功：
-
-:-: ![](.topwrite/assets/image_1736148015509.png =445)
-
-##### 配置同步规则
-
-:-: ![](.topwrite/assets/image_1736148027202.png =443)
-
-##### 提交
-
-配置完成后，提交多表实时同步任务：
-
-:-: ![](.topwrite/assets/image_1736148034594.png =427)
-
-##### 运维
-
-运维多表实时同步任务：
-
-:-: ![](.topwrite/assets/image_1736148045501.png =425)
-
-##### 启动

-
-:-: ![](.topwrite/assets/image_1736148052375.png =426)
-
-第一次启动该多表实时同步任务时，选择“无状态启动”和“全量数据同步”：
-
-:-: ![](.topwrite/assets/image_1736148058726.png =426)
-
-启动后即可查看任务运行的详细情况。等待全量同步完成后，系统会自动开始进行增量实时同步。
-
-##### 进度查看
-
-全量同步进行中：
-
-:-: ![](.topwrite/assets/image_1736148083158.png =446)
-
-全量同步完成。
-
-开始进行实时同步：
-
-:-: ![](.topwrite/assets/image_1736148107686.png =430)
-
-##### 增量实时同步
-
-往 PG 数据库插入增量数据，进行增量实时同步。在 VS Code 里新建一个文件“[rt\_data\_generate\_insert\_into\_pg.py](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/rt_data_generate_insert_into_pg.py)”，将如下代码复制进去：

-
-在 VS Code 里新建一个“终端”，并运行如下命令激活在“环境设置”步骤创建的 Python 环境。如果已在 cz-ingest-examples 环境里，请跳过。
-
-```Shell
-conda activate cz-ingest-examples
-```
-
-然后在同一终端里运行如下命令：
-
-将 100000 条数据插入到 ingest_demo.lift_tickets_data 表中，每次插入 100 行，每批次休眠 10 秒。
-
-```Shell
-python rt_data_generate_insert_into_pg.py 100000 100 10
-```
-
-在云器 Lakehouse Studio 查看实时同步进展：
-
-:-: ![](.topwrite/assets/image_1736148122833.png =484)
-
-#### 下一步建议
-
-在数据源中插入新数据，查看增量同步的结果。
-
-“停止”该同步任务。运行该任务的虚拟计算集群设置了自动停止，会在作业停止后的设定时间（秒数）内停止运行，从而节省费用，实现按需运行。

-# 将数据导入云器 Lakehouse 的完整指南
-
-## 数据入仓：通过云器 Lakehouse Studio 以 SQL INSERT 方式导入数据
-
-#### 概述
-
-在云器 Lakehouse 平台中，用户可以使用 `INSERT` 语句将数据导入目标表。该语句支持多种导入方式，包括直接插入值、从其他表查询导入数据以及从外部文件导入数据。以下文档将详细介绍如何使用 `INSERT` 语句导入数据，以及其使用场景、操作示例和注意事项。
-
-#### 方式一：使用`INSERT INTO VALUES`语句导入数据
-
-##### 使用场景
-
-适用于手动导入少量数据，用于调试与测试。对于大规模数据处理，通常建议采用批量插入、流式数据导入等更加高效的方法来确保数据导入过程的稳定性和性能。
-
-##### 实现步骤
-
-导航到 开发 -> 任务，单击 “+” 新建一个 SQL 任务（以下两种方式都在同一个任务里实现）。
-
-![](.topwrite/assets/image_1736148597217.png =470)
-
-您可以使用 `INSERT INTO VALUES` 语句直接插入数据。多个记录之间使用逗号分隔。
-
-```SQL
---方式一：使用INSERT INTO SELECT FROM TABLE语句插入
-DROP TABLE IF EXISTS ingest.lift_tuckets_import_by_insert_into_values;
-CREATE TABLE IF NOT EXISTS ingest.lift_tuckets_import_by_insert_into_values(
-  `txid` string,
-  `rfid` string,
-  `resort` string,
-  `purchase_time` timestamp_ltz,
-  `expiration_time` date,
-  `days` int,
-  `name` string,
-  `address_street` string,
-  `address_city` string,
-  `address_state` string,
-  `address_postalcode` string,
-  `phone` string,
-  `email` string,
-  `emergency_contact_name` string,
-  `emergency_contact_phone` string);
-
-INSERT INTO ingest.lift_tuckets_import_by_insert_into_values (
-  txid, rfid, resort, purchase_time, expiration_time, days, name, address_street, 
-  address_city, address_state, address_postalcode, phone, email, emergency_contact_name, emergency_contact_phone
-) VALUES
-('0056b1f3-79b0-455c-80e9-3b80c45ac61e', '0x39eb22cbb32e9e115917b6', '长安壹号',
-  timestamp_ltz '2023-08-30 12:00:00', TO_DATE('2025-03-12', 'yyyy-MM-dd'), 2, '佘雪梅', '广州路S座', 
-  '艳市', '河北省', 853592, 13912709719, 'pchen@example.net', '林楠', 18041629236),
-('52016065-1399-48cc-aed2-d4a525d90452', '0x121a00c15e41d8c3410c7490', '海底捞',
-  timestamp_ltz '2023-08-30 12:00:00', TO_DATE('2025-10-16', 'yyyy-MM-dd'), 3, '韦超', '上海路R座', 
-  '伟县', '香港特别行政区', 123342, 18259131600, 'panyan@example.net', '魏玉兰', 14795983190);
-```
-
-#### 方式二：使用`INSERT INTO SELECT`语句导入数据
-
-##### 使用场景
-
-如果需要从另一个表中导入数据，可以使用 `INSERT INTO SELECT` 语句。您可以选择导入整个表的数据，也可以进行 ETL 操作，如选择部分列或进行数据转换。
-
-##### 实现步骤
-
-导航到 开发 -> 任务，单击 “+” 新建一个 SQL 任务。
-
-```SQL
---方式二：使用INSERT INTO SELECT FROM TABLE语句插入
-DROP TABLE IF EXISTS ingest.lift_tuckets_import_by_insert_into_select;
-CREATE TABLE IF NOT EXISTS ingest.lift_tuckets_import_by_insert_into_select(
-  `txid` string,
-  `rfid` string,
-  `resort` string,
-  `purchase_time` timestamp_ltz,
-  `expiration_time` date,
-  `days` int,
-  `name` string,
-  `address_street` string,
-  `address_city` string,
-  `address_state` string,
-  `address_postalcode` string,
-  `phone` string,
-  `email` string,
-  `emergency_contact_name` string,
-  `emergency_contact_phone` string);
-  
-INSERT INTO ingest.lift_tuckets_import_by_insert_into_select
-SELECT * FROM ingest.lift_tuckets_import_by_studio_web;
-```
-
-#### 方式三：从Volume文件查询数据并导入
-
-##### 使用场景
-
-云器 Lakehouse 支持通过 `INSERT INTO` 与 `SELECT FROM VOLUME` 结合使用，直接从外部文件（如云存储中的 CSV 或 Parquet 文件）导入数据。
-
-注：在 ZettaPark 上传数据文件的案例中，已将 CSV、JSON 格式的数据文件上传至云器 Lakehouse 的数据湖对象 ingest_demo 中。
-
-##### 实现步骤
-
-导航到 开发 -> 任务，单击 “+” 新建一个 SQL 任务。
-
-```SQL
-DROP TABLE IF EXISTS ingest.lift_tuckets_import_by_insert_into_select_from_volume;
-CREATE TABLE IF NOT EXISTS ingest.lift_tuckets_import_by_insert_into_select_from_volume(
-  `txid` string,
-  `rfid` string,
-  `resort` string,
-  `purchase_time` timestamp_ltz,
-  `expiration_time` date,
-  `days` int,
-  `name` string,
-  `address_street` string,
-  `address_city` string,
-  `address_state` string,
-  `address_postalcode` string,
-  `phone` string,
-  `email` string,
-  `emergency_contact_name` string,
-  `emergency_contact_phone` string);
-
-
---使用SELECT文件的结果导入数据
---查看上传至Volume的数据文件
-SHOW VOLUME  DIRECTORY ingest.ingest_demo;
-
---使用CSV格式数据文件导入
-INSERT INTO ingest.lift_tuckets_import_by_insert_into_select_from_volume 
-select * from volume ingest_demo(
-  `txid` string,
-  `rfid` string,
-  `resort` string,
-  `purchase_time` timestamp_ltz,
-  `expiration_time` date,
-  `days` int,
-  `name` string,
-  `address_street` string,
-  `address_city` string,
-  `address_state` string,
-  `address_postalcode` string,
-  `phone` string,
-  `email` string,
-  `emergency_contact_name` string,
-  `emergency_contact_phone` string
-) using csv
- options(
-    'header'='true',
-    'sep'=',',
-    'compression' = 'gzip'
- ) files('gz/lift_tickets_data.csv.gz');
- 
---使用JSON格式数据文件导入
-INSERT INTO ingest.lift_tuckets_import_by_insert_into_select_from_volume  
-select * from volume ingest_demo(
-        `txid` string,
-        `rfid` string,
-        `resort` string,
-        `purchase_time` timestamp_ltz,
-        `expiration_time` date,
-        `days` int,
-        `name` string,
-        `address_street` string,
-        `address_city` string,
-        `address_state` string,
-        `address_postalcode` string,
-        `phone` string,
-        `email` string,
-        `emergency_contact_name` string,
-        `emergency_contact_phone` string
-        ) using json
-options(
-'compression' = 'gzip'
-) files('gz/lift_tickets_data.json.gz');
-```
-
-除 CSV、JSON 格式外，云器 Lakehouse 还支持通过 SELECT FROM VOLUME 方式查询 Parquet、ORC、BSON 等开放格式的数据并导入。

-# 将数据导入云器 Lakehouse 的完整指南
-
-## 数据入湖：通过 ZettaPark PUT 文件实现数据入湖
-
-#### 概述
-
-通过云器 Lakehouse 提供的 ZettaPark Python 库，以 Python 编程的方式将在测试数据生成步骤中生成的数据上传到云器 Lakehouse 管理的数据湖中，实现数据入湖。
-
-数据湖操作需要新建一个数据湖连接和 Volume，然后就可以将数据 PUT 到数据湖中。
-
-#### 使用场景
-
-适合熟悉 Python 编程的用户，可以借助 Python 强大的编程能力和灵活性，通过 Python 和 DataFrame 进行数据清洗、转换等数据工程与数据准备工作，特别是与 AI 分析紧密相关的数据工作。
-
-#### 实现步骤
-
-你也可以[直接下载文件](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/put_data_to_datalake_by_Zettapark.ipynb)到本地。
-
-##### **将本地文件通过 Zettapark PUT 到云器 Lakehouse 管理的数据湖（Volume）**
-
-```Python
-# !pip install clickzetta_zettapark_python  -i https://pypi.tuna.tsinghua.edu.cn/simple
-```
-
-```Python
-from clickzetta.zettapark.session import Session
-import json,requests
-import os
-from datetime import datetime
-```
-
-##### **创建到云器 Lakehouse 的会话**
-
-```Python
-# 从配置文件中读取参数
-with open('config/config-ingest.json', 'r') as config_file:
-    config = json.load(config_file)
-
-print("正在连接到云器Lakehouse.....\n")
-
-# 创建会话
-session = Session.builder.configs(config).create()
-
-print("连接成功！...\n")
-```
-
-正在连接到云器 Lakehouse...
-
-连接成功！
-
-##### **将文件 PUT 到云器 Lakehouse 数据湖 Volume**
-
-请将 `data/` 改为在“测试数据生成”步骤中生成的数据存放目录。
-
-```Python
-for filename in os.listdir("data/"):
-        if filename.endswith(".gz"):
-            file_path = os.path.join("data/", filename)
-            session.file.put(file_path,"volume://ingest_demo/gz/")
-        if filename.endswith(".csv"):
-            file_path = os.path.join("data/", filename)
-            session.file.put(file_path,"volume://ingest_demo/csv/")
-        if filename.endswith(".json"):
-            file_path = os.path.join("data/", filename)
-            session.file.put(file_path,"volume://ingest_demo/json/")
-```
-
-```Python
-# 或者上传目录下所有的文件# session.file.put("../data/","volume://ingest_demo/gz/")
-```
-
-##### **再次同步数据湖 Volume 的目录到 Lakehouse**
-
-```Python
-session.sql(alter_datalake_sql).show()
-```
-
-\---------------------
-
-|result\_message |
-
-\---------------------
-
-| OPERATION SUCCEEDED |
-
-\---------------------
-
-##### **再次查看云器 Lakehouse 数据湖 Volume 上的文件**
-
-```Python
-results = session.sql("select * from directory(volume ingest_demo)").show()
-```
-
-\----------------------------------------------------------------------------------------------------------------------------
-
-|relative\_path |url |size |last\_modified\_time |

-
-\----------------------------------------------------------------------------------------------------------------------------
-
-##### **测试将数据湖上文件再拉回到本地**
-
-```Python
-session.file.get("volume://ingest_demo/gz/lift_tickets_data.json.gz","tmp/gz/")
-```
-
-\[GetResult(file='tmp/gz/lift\_tickets\_data.json.gz', size=11146044, status='DOWNLOADED', message='')]
-
-##### 校验数据湖文件的行数
-
-数据校验：检查文件行数。查询结果为 100000，与原文件行数一致。简单从行数判断，数据入湖正确。
-
-```Python
-datalake_data_verify_sql = """
-select count() from volume ingest_demo (txid string) using csv
- options(
-    'header'='true',
-    'sep'=',',
-    'compression' = 'gzip'
- ) files('gz/lift_tickets_data.csv.gz')
- limit 10
-"""

-# 将数据导入云器Lakehouse的完整指南
-
-## 数据入仓：通过Zettapark以SAVE\_AS\_TABLE方式加载数据
-
-#### 概述
-
-#### 使用场景
-
-SAVE\_AS\_TABLE方式会自动建表，从而简化了通过Zettapark以SQL INSERT方式加载数据需要手工建表的过程，同时SAVE\_AS\_TABLE会自动优化INSERT INTO，每次不是插入一条记录而是多条。
-
-#### 实现步骤
-
-在电脑上打开VS Code，创建一个名为 [py\_zettapark\_save\_as\_table.py ](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/py_zettapark_save_as_table.py)的文件，并将以下代码复制到py\_zettapark\_save\_as\_table.py文件中。
-
-```Python
-import json
-import gzip
-from clickzetta.zettapark.session import Session
-from datetime import datetime
-
-# 从配置文件中读取参数
-with open('config-ingest.json', 'r') as config_file:

-
-def save_as_table_to_clickzetta(session, schema, data):
-    print('Saving data to Clickzetta Lakehouse')
-
-    # Convert data to dataframe
-    df = session.create_dataframe(data, schema=schema)
-    
-    # Save dataframe as table
-    df.write.save_as_table(target_table_name, mode="overwrite", table_type="transient")
-    print(f"Data saved to table {target_table_name}")
-
-if __name__ == "__main__":
-    schema = None
-    data = []
-
-    # 打开压缩的 JSON 文件并读取内容
-    with gzip.open('lift_tickets_data.json.gz', 'rt', encoding='utf-8') as file:
-        for message in file:
-            if message.strip():  # 确保不是空行
-                record = json.loads(message)
-                if 'schema' in record:
-                    schema = record['schema']
-                else:
-                    data.append(record)
-    
-    save_as_table_to_clickzetta(session, schema, data)
-    session.close()
-    print("Ingest complete")
-```
-
-在VS Code里新建一个“终端”，并运行如下命令以激活在“环境设置”步骤中创建的Python环境。如果已在 `cz-ingest-examples` 环境中，请跳过此步骤。
-
-```
-conda activate cz-ingest-examples
-```
-
-然后在同一终端里运行如下命令：

-# 将数据导入云器Lakehouse的完整指南
-
-## 数据入仓：通过Zettapark以SQL INSERT方式加载数据
-
-#### 概述
-
-云器Lakehouse提供了和PySpark兼容的[Zettapark](ZettaparkQuickStart.md)，在流行的IDE（比如VS Code）里通过Python和SQL编程的方式，将数据加载到云器Lakehouse的表里。
-
-#### 使用场景
-
-这种方式可以方便地运行 SQL 并上传文件，加载数据的一种方法是对每条记录执行 SQL INSERT 语句，适合在 Python 编程环境里上传少量数据。虽然这是一种方便的数据插入方式，但是对大批量数据的加载效率不高，因为云器Lakehouse并不是一个传统的数据库，而是针对写入大批量数据进行了更多优化。
-
-#### 实现步骤
-
-在电脑上打开VS Code，创建一个名为 [py\_zettapark\_sql\_insert.py ](https://github.com/yunqiqiliang/clickzetta_quickstart/blob/main/a_comprehensive_guide_to_ingesting_data_into_clickzetta/py_zettapark_sql_insert.py)的文件，并将以下代码复制到py\_zettapark\_sql\_insert.py文件中。

-### 入门知识
-
-虚拟计算集群（Virtual Cluster，简称 VC 或集群）是云器 Lakehouse 提供数据处理和分析的计算资源对象。虚拟计算集群提供在 Lakehouse 中执行 SQL 作业所需的 CPU、内存、本地临时存储（SSD 介质）等资源。集群具备快速创建/销毁、扩容/缩容、暂停/恢复等特点，按照资源规格大小以及使用时长进行收费，暂停或删除后不产生费用。虚拟计算集群针对 ETL 和分析场景，提供通用型和分析型两种集群类型，以满足不同负载的隔离和优化需求。
-
-![](.topwrite/assets/image_1714992266569.png =700)
-
-### 教程步骤
-
-1.  **环境准备**：创建测试使用的计算集群。
-2.  **发起查询**：使用 Studio Web 环境创建 Python 任务对 Lakehouse 使用不同并发度进行连续查询，观察 Python 任务的执行日志结果，了解集群在不同并发请求下的快速扩缩容能力。
-3.  **清理环境**：删除测试使用的计算集群。
-
-通过以上步骤，您将能够了解如何配置和使用虚拟集群的弹性并发功能，并了解其性能表现。
-
-## 准备工作
-
-首先，通过 SQL 命令来创建分析型计算集群，并开启和设置弹性并发功能。
-
-本教程通过在“开发”模块运行 [Tutorial_Working_With_Concurrency_Scaling->Step01.Preparation] SQL 脚本任务来创建集群，并设置弹性扩容策略。
-![](.topwrite/assets/image_1725288058473.png)
-
-## 使用Python程序发起并发查询
-

-* [下载地址一](https://mvnrepository.com/artifact/com.clickzetta/clickzetta-java)
-* [下载地址二](https://central.sonatype.com/artifact/com.clickzetta/clickzetta-java/versions)
-
-```
-sh setup.sh
-```
-
-## 配置客户端连接
-
-### 方式1：命令行指定连接参数
-
-通过命令行指定连接参数的方式如下：
-
-```
-sh sqlline -d com.clickzetta.client.jdbc.ClickZettaDriver -u "<JDBC URL>" -n <user_name> -p <password>
-```
-
-JDBC URL 格式：
-
-```

-0: jdbc:clickzetta://xxxx.region_id.api.clickzetta.com> !properties test.properties.1
-Transaction isolation level TRANSACTION_REPEATABLE_READ is not supported. Default (TRANSACTION_READ_COMMITTED) will be used instead.
-1: jdbc:clickzetta://yyyyy.region_id.api.clickzetta.com> !go 0
-0: jdbc:clickzetta://xxxx.region_id.api.clickzetta.com>
-```
-
-## 运行SQL命令
-
-连接成功后，您可以在命令行客户端执行 Lakehouse SQL 命令。以下是一些SQL命令示例：
-
-切换要使用的 vcluster 和 schema
-
-```
-use vcluster default;
-use schema nyc_taxi_data;
-```
-
-查看当前 schema 中有哪些表
-
-```
-show tables;
-```
-
-![](.topwrite/assets/image_1699879449976.png)
-查询数据
-
-```
-select  * from fhv_trips_staging limit 10;
-```
-
-![](.topwrite/assets/image_1699879794959.png)
-
-## 退出客户端
-
-```
-!quit
-```
-
-## 备注
-
-通过在当前环境中设置以下环境变量，可以打开 debug 模式并输出日志文件，方便问题排查。
-
-```
-export SQLLINE_DEBUG_ENABLE=TRUE
-```

-# CONNECTION
-
-在Lakehouse中，CONNECTION对象扮演着至关重要的角色。它负责存储第三方服务的身份认证信息和访问管理凭据，从而实现在数据处理过程中保护敏感信息的目的。通过使用CONNECTION，用户无需将身份认证信息以明文形式暴露，从而确保数据的安全性。此外，CONNECTION还支持STS（Security Token Service）认证方式，允许跨账号授权访问Lakehouse以外的服务，进一步提高了数据访问的灵活性和安全性。
-
-## CONNECTION的类型
-
-根据其用途和连接的外部服务类型，CONNECTION对象主要分为以下三种类型：
-
-1. **API Connection**：这种类型的CONNECTION主要用于存储和保护第三方应用服务的身份认证信息。通过API Connection，Lakehouse可以安全地通过API调用来与这些服务进行交互。目前，API Connection支持的外部服务包括阿里云的函数计算FC和腾讯云的云函数服务。API Connection通常与External Function结合使用，以便在Lakehouse中远程调用这些服务。
-2. **Storage Connection**：Storage Connection主要用于存储第三方存储服务的身份认证信息，使得Lakehouse能够安全地访问和管理这些存储服务中的数据。目前支持的外部存储服务包括阿里云的对象存储OSS、腾讯云COS和AWS S3。
-3. **Catalog Connection**：在数据湖架构中，Catalog Connection 是一种关键组件，用于将数据湖与外部的元数据存储（例如 Hive Metastore）关联起来。通过创建 Catalog Connection，用户可以实现元数据的统一管理和访问，从而直接读取存储在外部系统中的数据。Lakehouse目前只支持连接Hive。
-
-## 创建和管理CONNECTION
-
-为了使用CONNECTION，用户需要了解如何创建、列出、查看详情以及删除CONNECTION。以下是这些操作的基本语法和使用示例：
-
-* **创建CONNECTION**：用户可以通过特定的创建语法来定义一个新的CONNECTION对象，其中需要指定CONNECTION的类型、名称以及相关的认证信息和参数。
-  例如，创建一个API Connection的语法如下：
-
-  ```sql
-  CREATE API CONNECTION conn_aliyun_java 
-    type cloud_function
-    provider = 'xxx'
-    region = 'xxx'
-    role_arn = 'acs:ram::13843xxxxxxxxxxxxx:role/czudfrole'
-    namespace = 'xxx'
-    code_bucket = 'xxx';
-  ```
-
-  创建一个Storage Connection的语法如下：
-
-  ```SQL
-  CREATE STORAGE CONNECTION [IF NOT EXISTS] connection_name 
-    TYPE COS
-    REGION = 'xxx'
-    APP_ID = 'xxx'
-    ACCESS_KEY='******'
-    SECRET_KEY='******';
-  ```
-
-  具体的语法和步骤可以参考[创建CONNECTION](CREATECONNECTION.md)文档。
-
-* **列出所有的CONNECTION**：用户可以使用列出语法来查看当前Lakehouse工作空间中所有的CONNECTION对象。例如，查看当前CONNECTION的命令如下：
-  ```sql
-  SHOW CONNECTIONS;
-  ```
-  这有助于用户管理和选择已有的CONNECTION进行操作。相关的命令和选项可以在[列出所有的CONNECTION](SHOWCONNECTIONS.md)文档中找到。
-
-* **查看CONNECTION详情**：为了更好地理解和管理CONNECTION，用户可能需要查看特定CONNECTION的详细信息。这包括认证信息、配置参数等。例如，查看一个API Connection详情的语法如下：
-  ```sql
-  DESCRIBE CONNECTION my_api_conn;
-  ```
-  查看详情的语法和方法在[查看CONNECTION详情](DESCCONNECTION.md)文档中有详细说明。
-
-* **删除CONNECTION**：当某个CONNECTION不再需要时，用户可以通过删除语法来移除它。例如，删除一个CONNECTION的命令如下：
-  ```sql
-  DROP CONNECTION my_api_conn;
-  ```
-  这有助于保持工作空间的整洁，并防止不必要的安全风险。具体的删除步骤和注意事项在[删除CONNECTION](DROPCONNECTION.md)文档中有所描述。

-# 流式SQL
-
->【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请联系我们的技术支持同学协助处理。
-
-
-
-流式SQL是Lakehouse平台推出的一种新型SQL调度模式，它采用微批处理运行机制，支持设置秒级的数据刷新间隔，类似于Spark Streaming的微批执行方式。与传统的定时调度相比，流式SQL能够显著减少提交和编译SQL的开销，因为它将提交的SQL转化为一个常驻进程，一旦达到设定的时间间隔，就会自动触发数据的运行和处理。流式SQL目前是面向需要数据新鲜度更高的场景，目前支持dt刷新和加工数据过程中含有table stream。
-
-为了更清晰地理解流式SQL的优势，我们可以将其与普通SQL的执行过程进行对比：
-
-**普通SQL执行过程**
-
-![](.topwrite/assets/image_1727083232762.png)
-
-* 语法解析器（Parser），词法分析，语法分析将SQL文本解析成抽象语法树（AST），语义分析，类型推导和检查。生产Logical Plan
-
-* 查询优化器（Optimizer）：通过Rule对Plan进行变换，根据cost model找出best plan
-
-  * RBO：基于规则的优化器，通过用户下发的SQL语句进行的优化，主要通过改下SQL，比如SQL子句的前后执行顺序等。比较常见的优化包括谓语下推、字段过滤下推、常量折叠、索引选择、Join优化等等
-  * CBO：基于代价的优化器，根据收集的统 计信息来计算每种执行方式的代价，进而选择最优的执行方式
-  * HBO：History-Based Optimizer，基于历史的优化器
-
-* 生成DAG图：DAG描述了执行计划映射到物理分布式集群的具体描述，根据执行计划，分布式执行，体现的是执行计划被物化到分布式系统上，具备的一些特性：比如并发度，数据传输方式等等，保证有序性和可靠性
-
-* Executor读取数据进行运算
-
-**流式SQL执行过程**
-
-1. **首次提交与物理执行计划生成**：
-
-   1. 在流式SQL首次提交时，系统会进行完整的编译过程，包括语法解析、查询优化和物理执行计划的生成。
-   2. 这一阶段生成的物理执行计划（DAG图）将被固化，用于后续的执行周期。
-
-2. **后续执行的优化**：
-
-   1. 物理执行计划生成并固化，后续的执行周期在大部分情况下将直接使用这一计划，无需再次进行编译。
-   2. 这意味着每次数据到达时，流式SQL可以跳过耗时的解析和优化步骤，直接进入执行阶段。
-   3. 在执行过程中，优化器也会监测每次要处理的数据量，如果数据量变化非常大使得执行计划不是最优时，优化器会重新生成物理执行计划并固化。
-
-#### 定时调度与流式SQL的对比
-
-* **普通定时调度**：
-
-  * 每次执行前都需要重新解析和优化SQL，这增加了额外的开销。
-  * 时间间隔通常需要设置得相对较大，以减少调度的频率和资源消耗。
-
-* **流式SQL**：
-
-  * 由于省去了重复的编译过程，流式SQL可以支持更小的时间间隔，实现更高频的数据更新和处理。
-  * 这种模式特别适合需要实时或近实时数据处理的应用场景
-
-# 流式SQL适用场景
-
-流式SQL的引入，为数据处理带来了更高的灵活性和实时性。在动态表（dynamic table）的DDL（Data Definition Language）定义中，调度的时间间隔通常有一个最小值，例如一分钟。这意味着数据的更新和处理至少会有一个一分钟的延迟。然而，流式SQL通过微批处理机制，允许将这个时间间隔缩短到秒级，从而实现更快速的数据反应和处理。
-
-* **实时数据处理**：流式SQL能够快速响应数据变化，适合需要实时数据处理和分析的应用。
-* **高频数据更新**：对于需要频繁更新数据的系统，流式SQL可以减少每次更新的延迟，提高数据处理的实时性。
-
-# 流式SQL使用限制
-
-* 要求流式是动态表或者SQL加工中含有table stream。普通SQL暂时不支持
-* 作业必须运行在分析型（ap）集群
-* 目前只支持在Lakehouse 界面开发流式SQL。一个SQL文件中只能处理一个DML SQL任务
-
-# 流式SQL如何使用
-
-## 开发流式SQL任务
-
-1. 数据开发中新建流式SQL节点

-
-2. 编写SQL任务
-
-提交的SQL任务中只能有一条DML SQL语句。在开发阶段可以编写任何SQL，目前是没有限制。但是在启动阶段会校验SQL是不是符合流式SQL。
-
-流式SQL要求
-
-* 要求流式是动态表或者SQL加工中含有table stream
-* 作业必须运行在分析型（ap）集群
-* 一个SQL文件中只能处理一个SQL任务
-
-**配置处理间隔**

-
-# 流式SQL使用具体案例
-
-## TABLE STREAM使用流式SQL
-
-本次案例使用TABLE STREAM实现缓慢变化维第一种覆盖更新。并使用流失SQL的微批处理保证数据的新鲜度。
-
-[缓慢变化维度](https://developer.baidu.com/article/detail.html?id=371363)（Slowly Changing Dimension，SCD）是数据仓库中处理数据变更的一种方法。在数据仓库中，数据通常是从多个数据源整合而来的。随着时间的推移，这些数据源中的数据可能会发生变化，例如更新、添加或删除。缓慢变化维度是一种用于处理和更新这些数据变化的技术。SCD有多种类型，SCD1：覆盖更新，SCD2：历史记录等
-
-我们模拟当原表数据发生变化时，通过流失SQL加工，缓慢变化维表也会变化。
-
-1. 新建一个普通SQL节点。执行一下SQL。用于创建原表并插入一些测试数据，和开启table stream捕获原表的变化
-
-```SQL
-create schema continuous_job;
-drop table if exists continuous_job.test_table_offset;
-drop table stream  if exists continuous_job.test_table_offset_stream;
--- 创建原表
-CREATE TABLE continuous_job.test_table_offset (id INT, name VARCHAR, age INT);
---创建table stream时必须开启
-ALTER TABLE continuous_job.test_table_offset set PROPERTIES ('change_tracking' = 'true');
-CREATE table stream continuous_job.test_table_offset_stream ON TABLE continuous_job.test_table_offset
-WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
--- 插入一些数据到测试表
-INSERT INTO continuous_job.test_table_offset VALUES
-  (1, 'Alice', 20),
-  (2, 'Bob', 25),
-  (3, 'Charlie', 30),
-  (4, 'David', 35),
-  (5, 'Eve', 40);
-```
-
-2. 创建一张缓慢变化维表，用于保持和原表一致
-
-```SQL
-drop table  if exists test_table_offset_consume;
--- 创建目标表
-CREATE TABLE continuous_job.test_table_offset_consume (id INT, name VARCHAR, age INT);
-```
-
-3. 新建一个流式SQL节点，将下面SQL复制到流式SQL节点中。我们设置20秒间隔处理一次数据
-
-```SQL
-MERGE INTO continuous_job.test_table_offset_consume target USING continuous_job.test_table_offset_stream source_stream ON target.id = source_stream.id WHEN MATCHED
-AND source_stream.__change_type = 'UPDATE_AFTER' THEN update set target.age = source_stream.age WHEN MATCHED
-AND source_stream.__change_type = 'DELETE' THEN DELETE WHEN NOT MATCHED
-AND source_stream.__change_type = 'INSERT' THEN
-INSERT VALUES (target.id, target.name, target.age);
-```
-
-![](.topwrite/assets/image_1727083470402.png)
-
-4. 提交流式SQL，并且在运维中心点击启动
-
-![](.topwrite/assets/image_1727083486439.png)
-
-5. 通过更新原表数据，流式SQL运行成功之后。SCD表也会和流式SQL保持一致
-
-* 普通节点执行SQL
-
-```SQL
--- 更新一些原表数据
-update continuous_job.test_table_offset set age = age + 5 WHERE id = 1 OR id = 3;
---等待20s，continues job执行成功。校验scd表和原表数据是否一致
-select "test_table_offset", * from continuous_job.test_table_offset
-union all
-SELECT "test_table_offset_consume",* FROM continuous_job.test_table_offset_consume;
-
--- 删除一些数据到测试表
-DELETE FROM continuous_job.test_table_offset WHERE id = 2 OR id = 4;
---等待20s,continues job执行成功。校验scd表和原表数据是否一致
-select "test_table_offset", * from continuous_job.test_table_offset
-union all
-SELECT "test_table_offset_consume",* FROM continuous_job.test_table_offset_consume;
-```
-
-6. 清理环境
-
-* 运维中心中停止流式SQL
-  ![](.topwrite/assets/image_1727083510506.png)
-
-* 删schema
-
-```SQL
-drop schema continuous_job;
-```
-
-## Dynamic Table使用流式SQL
-
-本次案例使用dynamic table对数据按时间进行聚合。利用流式SQL微批调度提高数据新鲜度
-
-* 创建一ods表
-
-```SQL
-CREATE TABLE event_tb (
-    event STRING,
-    process DOUBLE,
-    event_time TIMESTAMP
-  );
-INSERT INTO event_tb VALUES
-  ('event-0', 20.0, TIMESTAMP '2023-09-20 14:43:13'),
-  ('event-0', 20.0, TIMESTAMP '2023-09-19 11:40:13'),
-  ('event-1', 21.0, TIMESTAMP '2023-09-19 14:30:14'),
-  ('event-1', 22.0, TIMESTAMP '2023-09-20 14:20:15');
-```
-
-* 使用动态表进行聚合。在普通SQL节点中创建动态表，注意不要在ddl中设置调度周期
-
-```SQL
-CREATE dynamic table IF NOT EXISTS event_group_minute AS
-SELECT
-  event,
-  hour(event_time) hour,
-  year(event_time) year,
-  SUM(process) process_sum
-FROM
-  event_tb
-GROUP BY
-  event,
-  year(event_time),
-  hour(event_time);
-```
-
-* 新建流式SQL节点，将下面SQL复制到节点内容中，并配置10s运行一次
-
-```SQL
-refresh dynamic table event_group_minute;
-```
-
-![](.topwrite/assets/image_1727083531426.png)
-
-* 启动流式SQL刷新动态表
-
-![](.topwrite/assets/image_1727083554105.png)
-
-* 新建普通SQL节点，向表原表中插入一些数据，查询动态表是否刷新成功
-
-```SQL
-
-  INSERT INTO event_tb VALUES
-  ('event-0', 20.0, TIMESTAMP '2024-09-20 14:43:13'),
-  ('event-0', 20.0, TIMESTAMP '2024-09-19 11:40:13'),
-  ('event-1', 21.0, TIMESTAMP '2024-09-19 14:30:14'),
-  ('event-1', 22.0, TIMESTAMP '2024-09-20 14:20:15');
-  
-  --等待10s观察动态表变化
-  select * from event_group_minute;  
-```

-# 功能描述
-
-将数据从对象存储中的文件加载到表中。这些文件必须存在于对象存储中。
-
-* 目前支持的对象存储位置为腾讯云COS、阿里云OSS和AWS S3。当前只支持 Volume 对象存储
-* 目前不支持跨云厂商导入。比如您的Lakehouse开服在阿里云而对象存储是腾讯云
-
-# 语法
-
-```SQL
---直接从VOLUME中导入数据
-COPY INTO|OVERWRITE table_name
- [PARTITION (partition_column_name = partition_column_val)]
-FROM VOLUME volume_name
-[( <column_name> <column_type>,...) ]
-USING CSV | PARQUET | ORC | BSON
-OPTIONS(
-  FileFormatParams
-) 
-FILES('filename1','fiename2'...)|SUBDIRECTORY 'path'|REGEXP <pattern>
-PURGE=TRUE
-ON_ERROR=TRUE|ABORT;
-
---导入过程中进行转化
-COPY INTO table_name FROM (
-SELECT  <column_name>,... 
-FROM VOLUME <volume_name>
-[(<column_name> <column_type>,...) ]
-USING CSV|PARQUET|ORC 
-OPTIONS(
-  FileFormatParams
-) 
-FILES|SUBDIRECTORY|REGEXP <pattern>
-)
-PURGE=TRUE
-ON_ERROR=CONTINUE|ABORT;
-```
-
-### 使用说明
-
-COPY INTO 语句后面可以直接使用 VOLUME 查询语法，可以在导入过程中直接转换数据，VOLUME 查询[参考结构化、半结构化数据分析](structure_data_analysis.md)
-
-### **参数说明**：
-
-* **OVERWRITE**\|**INTO**:
-  * **INTO**：追加模式。使用 `INTO` 子句进行数据导入时，新数据将被追加到目标表，这种模式不会删除或修改表中的现有数据。
-  * **OVERWRITE**：覆盖模式。使用 `OVERWRITE` 子句进行数据导入时，目标表中的现有数据将被清空，然后导入新数据。这种模式适用于需要用新数据完全替换旧数据的场景。
-
-```
---向表中追加数据
-CREATE TABLE birds (
-    id INT,
-    name VARCHAR(50),
-    wingspan_cm FLOAT,
-    colors STRING
-);
-COPY INTO birds FROM 
-VOLUME  my_volume
-USING csv
-SUBDIRECTORY 'dau_unload/read/';
---覆盖表中的的数据
-COPY OVERWRITE birds FROM 
-VOLUME  my_volume
-USING csv
-SUBDIRECTORY 'dau_unload/read/';
-```
--  [PARTITION (partition_column_name = partition_column_val)],直接指定分区列的值，例如 `PARTITION (dt='shanghai')`。
-* **column\_name**和**column\_type**：可选，lakehouse支持自动识别文件schema。推荐不填写。当指定文件中包含的列名和类型时，需与文件中预定义的列类型相匹配，
-  * 自动识别文件 schema 对于 CSV 文件则会自动生成字段，字段编号以 f0 开始。目前自动识别的类型为 int、double、string、bool。
-  * 对于parquet、orc格式将会根据文件中存储的字段名和类型自动识别。如果指定的文件中列的个数不一致，LakeHouse 会尝试合并，无法合并则会报错。
-  ```
-  --指定volume中的列类型和名字
-  COPY OVERWRITE birds FROM 
-  VOLUME  my_volume(id int,name string,wingspan_cm float,colors string)
-  USING csv
-  SUBDIRECTORY 'dau_unload/read/';
-  --自动探查volume中的列类型和名字
-  COPY OVERWRITE birds FROM 
-  VOLUME  my_volume
-  USING csv
-  SUBDIRECTORY 'dau_unload/read/';
-  ```
-* **FileFormatParams**：多个参数使用逗号分隔，字符串形式的'key'='value'
-    * CSV 格式：支持以下文件参数组合
-      * sep：列分隔符，默认为 ”,“。最多支持长度为 2 的字符，例如：`'sep'=','`、`sep='||'`或者`sep = '\001'`：使用 Hive 默认的字段分隔符（不可见字符）
-      * compression：配置文件压缩格式。支持的压缩格式有：gzip/zstd/zlib。例如：`'compression'='gzip'`
-      * lineSep：行分隔符，默认会将 `\r\n` 与 `\n` 都识别为换行。最多支持长度为 2 的字符，例如：`'lineSep'='$'`使用 `$` 作为行分隔符。`lineSep = '\r\n'`使用 Windows 风格的换行符
-      * quote：用于包裹包含特殊字符的字段内容，避免解析错误。默认值为双引号 "，当字段内容包含默认引用符（"）时必须指定。
-        例如：导入数据为 `{"key":"value"}` 这类含双引号的 JSON 字符串时，需改用其他字符包裹，例如指定 `quote = r'\0'`，空字符`\0`方案需确保数据中不存在该字符。
-      * header：是否解析表头，默认为 false。布尔类型，例如：`'header'='true'`
-      * timeZone：配置时区，没有默认值。用于指定文件中时间格式的时区。例如：`'timeZone' = 'Asia/Shanghai'`
-      * escape：用于转义已加引号的值中的特殊字符，仅支持单字节字符。默认值为”\“，例如：`'escape'=r'\'`。转义字符用于解释数据文件中字段分隔符或换行符的特殊含义。如果某一行以反斜杠结尾，则该反斜杠会转义文件格式选项中指定的换行符或回车符（`lineSep`）。因此，加载操作会将此行和下一行视为一行数据。如果不需要这种转义行为，可以将转义字符设置为其他字符
-      * nullValue: 用于判定什么样的内容应该被视为 Null，默认值为 \`""\`，例如 \`'nullValue'='\\\N'\` 或者 \`'nullValue'=r'\N'\`。为了避免在不确定何时需要转义的情况下手动处理转义字符，Lakehouse 支持在字符串前添加 `r` 前缀，表示字符串中的转义字符不会被转义，可以直接输入到表达式中运行。
-       * multiLine: 是否有跨行的 csv 记录，默认值为 `false`，如果有这样的记录，需要配置 `multiLine='true'`
-    
-    
-    ```
-    --指定分隔符和quote
-    COPY OVERWRITE birds FROM 
-    VOLUME  my_volume
-    USING csv
-    OPTIONS('sep'='|','quote'='"')
-    files('dau_unload/part00001.csv');
-    ```
-    
-    * JSON格式:
-      * compression: 源文件/目标文件是否压缩，默认不压缩，配置如 `'compression'='gzip'`
-      ```
-      --导入json数据
-      COPY OVERWRITE birds FROM 
-      VOLUME  my_volume
-      USING json
-      files('dau_unload/part00001.json');
-      ```
-        * explodeArray：默认值 true， 可选值 false。在 JSON 内容是数组开头时使用。为 true 时认为 schema 是数组内单个元素的 schema，为 false 时认为 schema 是数组本身的 schema。
-    * Parquet , ORC , BSON 格式
-    * ```
-      --导入parquet数据
-      COPY OVERWRITE birds FROM 
-      VOLUME  my_volume
-      USING parquet
-      files('dau_unload/part00001.parquet');
-      ```
-
-* **FILES**：用于指定要读取的具体文件。支持指定多个相同格式的文件。文件路径为创建 Volume 时指定的子文件路径。` `例如：`files('part-00002.snappy.parquet','part-00003.snappy.parquet')`。
-* **SUBDIRECTORY**：指定子路径。用于指定要读取的子路径。读取时会递归地加载该目录下的所有文件。例如：`subdirectory 'month=02'。`
-* ```
-  COPY OVERWRITE birds FROM 
-  VOLUME  my_volume(id int,name string,wingspan_cm float,colors string)
-  USING csv
-  SUBDIRECTORY 'dau_unload/read/';
-  ```
-* **REGEXP**\<pattern>：正则表达式匹配。正则路径匹配基于url，您可通过`SHOW VOLUME DIRECTORY my_tx_volume;`命令查看url。例如，`regexp 'part-.*.parquet'`可匹配以“part-”开头且以“.parquet”结尾的文件。需要注意的是，正则表达式匹配的目标是文件的**完整的对象存储路径**（如 's3://cz-udf-user/volume-data/1234321.csv.gz'），而不是文件在 Volume 对象中的相对路径。
-
-* **PURGE=TRUE**：当设置此参数时，表示在数据导入成功后，将删除对象存储中的源文件。这有助于节省存储空间，特别是在处理大量数据时。如果导入操作失败，源文件将不会被删除。
-* **ON_ERROR=CONTINUE|ABORT**:控制当数据加载过程中遇到错误时的处理策略。添加此参数后，会返回导入文件列表。
-  * `CONTINUE`：跳过错误行，继续加载后续数据。使用场景：容忍部分错误，要求最大限度完成数据加载。目前忽略的错误只支持文件格式不匹配，例如命令中指定的是 zip 压缩格式但文件中实际是 zstd 压缩。
-  * `ABORT`：立即终止整个 COPY 操作。使用场景：严格数据质量要求场景，任何错误都需人工介入检查
-

-# 注意事项
-
-* 导入数据时建议您选择通用型计算集群(GENERAL PURPOSE VIRTUAL CLUSTER),通用型计算资源更加适合跑批量作业和加载数据作业
-* 建议导入数据时选择同一个 Region，这样可以避免公网传输费用。在同一个 Region 且同一个云厂商内，数据传输通过内网进行。

-# 创建腾讯云存储连接
-
-本步骤的目标是：允许 Lakehouse 集群访问腾讯上的对象存储 COS。为了完成这个目标，可以通过腾讯云**访问管理**提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
-
-## 基于访问密钥
-
-```sql
-CREATE STORAGE CONNECTION my_conn 
-  TYPE COS
-  ACCESS_KEY = '<access_key>'
-  SECRET_KEY = '<secret_key>'
-  REGION = 'ap-shanghai'
-  APP_ID = '1310000503';
-```
-
-### 参数：
-
-* **TYPE**：为对象存储类型，腾讯云应填写 `COS`（大小写不限）
-
-* **ACCESS\_KEY / SECRET\_KEY**：为腾讯云的访问密钥，获取方式参考：[访问密钥](https://cloud.tencent.com/document/product/598/40488)
-
-* **REGION**：指腾讯云对象存储 COS 的数据中心所在的地域。相同地域内云器Lakehouse访问腾讯云COS时，COS服务将自动路由至内网访问。具体取值请参考腾讯云文档：[地域和访问域名](https://cloud.tencent.com/document/product/436/6224)。
-
-* **APP\_ID**：腾讯云存储桶的命名由存储桶名称（BucketName）和 APPID 两部分组成，两者以中划线“-”相连。例如 `examplebucket-1310000503`，其中 `examplebucket` 为用户自定义，`1310000503` 为系统生成数字串（APPID）。
-
-## 基于角色授权
-
-### STEP1: 数据创建权限策略 (LakehouseAccess )：
-
-* 登录腾讯云，进入**访问管理**产品控制台
-* 在**访问管理**页面左侧导航栏进入**策略**，在权限控制界面选择 **新建自定义策略** -> **按策略生成器创建** -> **可视化策略生成器**。
-* 在**可视化策略生成器**页签中：**服务**（**Service**）: 选择 **对象存储(cos**)；**操作（Action**）：选择**全部操作**（可根据实际需要的操作，做更细粒度的选择）；**资源（Resource**）：根据需要选择**全部资源**或者**特定资源**。本示例中选择特定资源，为上海区的` cz-volume-sh-1311343935`![](.topwrite/assets/20240625-211734.jpeg)
-* 点击**下一步**，填写**策略名称**为 LakehouseAccess 和描述后，点击**完成**
-
-### STEP2：客户侧创建角色（LakehouseRole）
-
-* 进入腾讯云**访问管理**产品控制台
-* 在**访问管理**页面左侧导航栏进入**角色** -> **新建角色** -> **腾讯云账户**， 选择**其他主账号**，在 **账号ID** 中输入 `100029595716`（云器的腾讯云主账号），其它选项保持默认，点击**下一步**
-* 在**配置角色策略**配置中，将刚才新建的 LakehouseAccess 自定义策略授权给当前角色。点**击下一步**，在**角色命名**中填写 `LakehouseRole `完成创建。
-* 创建成功后，在角色列表中，进入角色 `LakehouseRole` 的详情页，获取该角色的 RoleARN 信息：  `qcs::cam::uin/1000*******:roleName/LakehouseRole`
-
-### STEP3：Lakehouse 侧创建 Connection
-
-* 在 Studio 或者 Lakehouse JDBC 客户端中执行以下命令：
-
-```
-CREATE STORAGE CONNECTION my_tx_connection_arn
-   TYPE cos
-   REGION = 'ap-shanghai'
-   ROLE_ARN = 'qcs::cam::uin/1000********:roleName/LakehouseRole'
-   APP_ID = '131****35';
-```
-
-^
-
-> 注意：为了防止 ROLE\_ARN 被第三方获取进行未授权的数据访问，可以使用` EXTENRAL ID` 作为一种额外的验证层，确保只有当请求中包含了预设的 `EXTERNAL ID` 时，这一访问才会被允许。这意味着即使第三方知道了其他一些访问信息（如角色ARN），没有正确的 `EXTERNAL ID` 也无法访问资源。
-
-* 在创建存储连接的过程中，Lakehouse 会生成此EXTERNAL ID，可以将此EXTERNAL ID 配置到 COS 账号的角色校验中实现访问控制：
-
-```
--- 查看 EXTERNAL ID 
-DESC CONNECITON my_tx_connection_arn ;
-```
-
-![](.topwrite/assets/20240625-214538.jpeg)
-
-^
-
-* 客户侧：进入腾讯云**访问管理**控制台中，**角色** -> **LakehouseRole** -> **角色载体**-> **管理载体**，选择 **添加账户** -> 选择**当前主账号**，并填写主账号ID：`100029595716`（云器的腾讯云主账号），并勾选**开启校验**，输入刚才 DESC 结果中的 EXTERNAL\_ID，点击 **确定**-> **更新**

-## 案例说明
-
-API CONNECTION 主要应用于 EXTERNAL FUNCTION 的创建。EXTERNAL FUNCTION 的使用如下过程
-
-* 用户开通云上的函数计算服务（如阿里云的函数计算FC）和对象存储服务
-* 将函数执行代码 & 可执行文件、依赖的库、模型和数据文件，打包上传至对象存储
-* 并且授予云器 Lakehouse 操作上述服务和访问函数文件的权限
-* 用户在云器 Lakehouse SQL 语句中调用 EXTERNAL FUNCTION
-* 云器 Lakehouse 根据提供的服务地址和认证信息发送 http 请求调用运行函数
-* 云器 Lakehouse 获取响应信息返回结果
-  因此您必须开通函数计算服务和对象存储服务。并且授权给云器 Lakehouse 权限
-
-### 阿里云创建API CONNECTION
-
-* **环境准备**
-  EXTERNAL FUNCTION 依赖阿里云的 "[对象存储](https://oss.console.aliyun.com/overview)" 和 "[函数计算](https://fcnext.console.aliyun.com/overview)" 服务, 请确保相关服务已开通
-
-* 步骤1: 用户开通云上的函数计算服务（如阿里云的函数计算FC）和对象存储服务
-
-* 步骤2.  阿里云侧操作：在阿里云 RAM 控制台中创建权限策略 (CzUdfOssAccess )：注意：需要用户具有RAM权限
-  * 访问阿里云访问控制（RAM）[产品控制台](https://ram.console.aliyun.com/policies)
-  * 左侧导航栏 **权限管理** -> **权限策略**，在权限控制界面选择 搜索**AliyunFCFullAccess**->编辑 **AliyunFCFullAccess** 权限策略 添加下面"acs\*\*:**Service**": "**fc.aliyuncs.com**"\*\*部分
-    ```JSON
-    {
-        "Version": "1",
-        "Statement": [
-            {
-                "Action": "fc:*",
-                "Resource": "*",
-                "Effect": "Allow"
-            },
-            {
-                "Action": "ram:PassRole",
-                "Resource": "*",
-                "Effect": "Allow",
-                "Condition": {
-                    "StringEquals": {
-                        "acs:Service": "fc.aliyuncs.com"
-                    }
-                }
-            }
-        ]
-    }
-    ```
-
-* 步骤3:在阿里云 RAM 控制台中创建权限策略 (CzUdfOssAccess )：注意：需要用户具有RAM权限
-
-  * 访问阿里云访问控制（RAM）产品控制台
-  * 左侧导航栏 **权限管理** -> **权限策略**，在权限控制界面选择 **创建权限策略**
-  * 在**创建权限策略**页面选择 **脚本编辑** 的页签，将下面`  [bucket_name_1|2|3]  `替换为实际的 OSS bucket 名称。注意：按照阿里云OSS 的约定，相同的bucket 需要有两条Resource条目：`"acs:oss:*:*:bucket_name_1" `与 `"acs:oss:*:*:bucket_name_1/*"`同时存在才能达到授权效果：
-
-  ```JSON
-  {
-      "Version": "1",
-      "Statement": [
-          {
-              "Effect": "Allow",
-              "Action": [
-                  "oss:GetObject",
-                  "oss:ListObjects",
-                  "oss:PutObject",
-                  "oss:DeleteObject"
-              ],
-              "Resource": [
-                  "acs:oss:*:*:bucket_name_1",
-                  "acs:oss:*:*:bucket_name_1/*",
-                  "acs:oss:*:*:bucket_name_2",
-                  "acs:oss:*:*:bucket_name_2/*",
-                  "acs:oss:*:*:bucket_name_3",
-                  "acs:oss:*:*:bucket_name_3/*"
-              ]
-          }
-      ]
-  }
-  ```
-
-* 步骤4： 阿里云控制台：在阿里云 RAM 中创建角色（如：CzUDFRole）：
-  * 在RAM 控制台左侧导航栏 **身份管理** -> **角色**，点击**创建角色**
-  * 在 **创建角色** 页面中，选择类型为 **阿里云账号**， 配置角色中填写自定义**角色名称 如** (CzUDFRole)，在**选择信任的云账号** 中选择 **其他云账号**，并写入：1384322691904283（云器 Lakehouse 上海的云主账号），点击**完成**
-  * 创建完成之后，点击**为角色授权**:
-  * 在**系统策略**中，将 **AliyunFCFullAccess** 策略授权给该角色 CzUDFRole
-  * 在**自定义策略**中，将刚创建的策略（**CzUdfOssAccess**）授权给该角色
-
-* 步骤5： 创建完成之后，点击**为角色授权**: 在**自定义策略**中，将刚创建的策略（CzUdfOssAccess）授权给该角色。在角色 CzUDFRole 详情页中，获取该角色的 RoleARN 信息：`'acs:ram::1222808864xxxxxxx:role/czudfrole'`![](.topwrite/assets/20231113-153016.jpeg)
-
-* 步骤6：将上面的role\_arn填入到语法参数重，创建阿里云函数计算连接
-
-```SQL
-CREATE API CONNECTION my_funciton_connection
-TYPE CLOUD_FUNCTION
-PROVIDER='aliyun'
-REGION='cn-hangzhou'
-ROLE_ARN='acs:ram::1757168149572678:role/czudfrole'
-CODE_BUCKET='function-compute-my1';
-```
-
-* 步骤7: desc connection 获取 external ID 信息：本实例中，external ID 为：`VW9UaGwYENBQ7cFp`
-  ```
-  DESC CONNECTION my_funciton_connection;
-  ```
-  ![](.topwrite/assets/image_1735638011131.png)
-  * 在阿里云 RAM -> 角色->  信任策略中，修改 CzUDFRole 的**信任策略** `"sts:ExternalId"` 部分：
-  ```Python
-  {
-    "Statement": [
-      {
-        "Action": "sts:AssumeRole",
-        "Condition": {
-          "StringEquals": {
-            "sts:ExternalId": "O0lQUogDJajHqnAQ"
-          }
-        },
-        "Effect": "Allow",
-        "Principal": {
-          "RAM": [
-            "acs:ram::1384322691904283:root"
-          ]
-        }

-  * 新建角色
-  * 选择 腾讯云账户
-  * 选择 **其他主账户 100029595716 (云器主账号**),其它选项保持默认，点击**下一步**
-  * 在**配置角色策略**配置中，将刚才新建的 LakehouseAccess 自定义策略授权给当前角色。点**击下一步**，在**角色命名**中填写 `LakehouseRole `完成创建。
-  * 创建成功后，在角色列表中，进入角色 `LakehouseRole` 的详情页，获取该角色的 RoleARN 信息：  `qcs::cam::uin/1000*******:roleName/LakehouseRole`
-  * 记住角色 RoleArn, 例如: `qcs::cam::uin/1000*******:roleName/LakehouseRole`
-* 步骤4:开通 COS 新建 BUCKET
-  * 新建 bucket 用于存放函数代码 region 保持和云器 Lakehouse 开服区域一致。如下图新建的 bucket 为myfunction![](.topwrite/assets/image_1735629660423.png)
-  * 授权给云器 Lakehouse 访问 bucket（myfunction）权限
-  * 进入**访问管理**[产品控制台](https://console.cloud.tencent.com/cam/policy)。找到刚刚新建的“LakehouseAccess”策略。选择编辑![](.topwrite/assets/image_1735627370589.png)

-
-> 注意：为了防止 ROLE\_ARN 被第三方获取进行未授权的数据访问，可以使用` EXTENRAL ID` 作为一种额外的验证层，确保只有当请求中包含了预设的 `EXTERNAL ID` 时，这一访问才会被允许。这意味着即使第三方知道了其他一些访问信息（如角色ARN），没有正确的 `EXTERNAL ID` 也无法访问资源。
->
-> 在 API CONNECTION 的过程中，云器 Lakehouse 会生成此EXTERNAL ID，可以将此EXTERNAL ID 配置到 COS 账号的角色校验中实现访问控制：

-
-* 步骤1: 用户开通云上的Lambda和对象存储服务
-
-* 步骤2: AWS侧创建权限策略 (LakehouseAccess )：
-  * 登录AWS 云平台，进入**身份与访问管理(IAM**) 产品控制台
-
-  * 在 IAM 页面左侧导航栏进入 **账户设置**，在 **Security Token Service (STS**) 中的 **终端节点** 列表中，找到当前实例对应云器 Lakehouse 的区域，如果 **STS  状态** 的状态为未开启请开启。
-
-  * 在 IAM 页面左侧导航栏进入 **策略**，在 **策略** 界面选择 **创建策略**，在策略编辑器中选择Json。
-
-  * 将要添加允许云器 Lakehouse 访问 S3 bucket 和目录的策略。下面是策略的样例，请用实际的bucket 和路径前缀名称替换 `<bucket>`&#x20;

-    ROLE_ARN = 'arn:aws-cn:iam::028022243208:role/CzUdfRole'
-    CODE_BUCKET = 'cz-udf-code'
-    NAMESPACE = 'default';
-```
-
-* 在创建存储连接的过程中，云器 Lakehouse 会生成此EXTERNAL ID，可以将此EXTERNAL ID 配置到步骤3 创建的 AWS IAM 角色（`LakehouseVolumeRole`）的 Trust Policy 中，实现附加的访问控制：
-
-```
--- 查看 EXTERNAL ID 
-DESC CONNECTION udf_noah ;
-```
-
-![](.topwrite/assets/image_1735802829076.png)
-
-* 在AWS IAM 的控制台，左侧导航栏中进入角色 **Roles**，找到步骤3 中创建的角色并进入角色详情页面，在 **Trust relationships** 中将 `sts:ExternalId `的值`  000000  `替换为 DESC 结果中的` EXTERNAL_ID`。点击**更新** 完成角色策略更新。
-
-### 后续：
-
-在完成 API CONNECTION 的创建之后，就可以继续创建外部函数，支持用 Python、Java 脚本处理云器 Lakehouse 中的数据。请参考: [创建外部函数](CREATE_EXTERNATL_FUNCTION.md)

-# 创建 Catalog Connection
-
-Catalog Connection 是一个关键组件，用于管理与第三方Catalog的连接信息。它的核心功能是为External Catalog提供访问认证，确保Lakehouse平台能够安全、无缝地访问和管理存储服务中的数据资源。
-
-# 支持的Catalog
-
-* Hive Catalog：通过连接 Hive Metastore，或者兼容 Hive Metastore 的元数据服务，Lakehouse 可以自动获取 Hive 的库表信息，并进行数据查询。
-* Databricks Unity Catalog：Unity Catalog 是 Databricks 上数据和 AI 资产的统一治理解决方案。在 Unity Catalog 中，所有元数据都注册在元存储中。任何 Unity Catalog 元存储中的数据库对象层次结构都分为三个级别，当您引用表、视图、卷、模型和函数时，它们表示为三级命名空间。通过连接 Databricks 的 Unity Catalog，Lakehouse 可以自动获取 Databricks 的库表信息，并进行数据查询。
-* 要求必须和 Lakehouse 所在的存储位置在同一云平台。例如，如果 Lakehouse 在 AWS，则 Databricks 存储须在 S3。
-
-# 创建Hive Catalog语法
-
-```SQL
-CREATE CATALOG CONNECTION if not exists connection_name
-    type hms
-    hive_metastore_uris='metastore_uris'
-    storage_connection='storage_connection';
-```
-
-**参数说明**
-
-* **connection\_name**: 连接的名称，需保证唯一性。
-* **type**: 连接类型，此处为 `hms`（Hive Metastore Service）。
-* **hive\_metastore\_uris**: Hive Metastore 的服务地址，格式为 `host:port`。port（端口）通常是 9083。
-* **storage\_connection**: 已创建的存储连接名称，用于访问对象存储或者hdfs服务。具体参考[CREATE STORAGE CONNECTION](create-storage-connection.md)
-

-# 创建 Databricks Unity Catalog 连接
-
-***
-
-## **概述**
-
-本文档详细说明如何使用 SQL 语句创建 Databricks Unity Catalog 连接。通过该连接，用户可以将外部系统与 Databricks Unity Catalog 集成，实现数据管理和共享。本文档涵盖语法、参数说明及配置要求。
-
-***
-
-## **语法**
-
-```SQL
-CREATE CATALOG CONNECTION IF NOT EXISTS <CONNECTION_NAME>
-    TYPE databricks
-    HOST = 'host_value'
-    CLIENT_ID = 'client_id_value'
-    CLIENT_SECRET = 'client_secret_value'
-    ACCESS_REGION = 'access_region_value';
-```
-
-**参数说明**
-
-* `CONNECTION_NAME`：连接的名称，用于标识该 Databricks Unity Catalog 连接。名称需唯一且符合命名规范。
-* `TYPE`：指定连接类型为 Databricks Unity Catalog。
-* `HOST`： Databricks 工作区的 URL 地址。通常格式为 `https://<workspace-url>`。  示例：`https://dbc-12345678-9abc.cloud.databricks.com`
-* `CLIENT_ID / CLIENT_SECRET`: 用于 OAuth 2.0 机器对机器（M2M）认证的客户端 ID。参考 [Databricks OAuth M2M 认证文档](https://docs.databricks.com/en/dev-tools/auth/oauth-m2m.html) 创建 OAuth 2.0 应用，并获取 `CLIENT_ID `和` CLIENT_SECRET`
-* `ACCESS_REGION`：Databricks 工作区所在的区域（Region），例如 `us-west-2` 或 us-east-1。
-
-## **示例**
-
-**Step 1：Databricks 准备**
-

-2. Metastore 开启 external data access
-   ![](.topwrite/assets/image_1739256232288.png)
-   ![](.topwrite/assets/image_1739256275537.png)
-3. 授权 service principal
-
-```SQL
---使用 service principal 的 id
-GRANT EXTERNAL USE SCHEMA ON SCHEMA quick_start.default TO `cf752cce-e2ca-4d03-8cdc-9f8f8aac43fc`;
-
-```
-
-以下是一个完整的示例，展示如何创建 Databricks Unity Catalog 连接：
-
-```SQL
-CREATE CATALOG CONNECTION IF NOT EXISTS my_databricks_conn
-    TYPE databricks
-    HOST = 'https://dbc-12345678-9abc.cloud.databricks.com'
-    CLIENT_ID = '12345678-9abc-def0-1234-56789abcdef0'
-    CLIENT_SECRET = 'abcdef1234567890abcdef1234567890'
-    ACCESS_REGION = 'us-west-2';
-```
-
-**Step 2：Lakehouse**
-以下是一个完整的示例，展示如何创建 Databricks Unity Catalog 连接：
-
-```SQL
-CREATE CATALOG CONNECTION IF NOT EXISTS my_databricks_conn    
- TYPE databricks   
- HOST = 'https://dbc-12345678-9abc.cloud.databricks.com'    
- CLIENT_ID = '12345678-9abc-def0-1234-56789abcdef0' 
- CLIENT_SECRET = 'abcdef1234567890abcdef1234567890'

-# 创建动态表（Dynamic Table）
-
-## 功能
-
-动态表（Dynamic Table）是一种特殊的表，它可以实时地根据查询语句来更新数据。动态表可以让您更加灵活地处理数据，提高查询效率。更多使用方式参考[动态表介绍](dynamic-table-introduce.md)和[增量计算部分](dynamic-table.md)
-
-## 普通动态表创建语法
-
-```SQL
-
-CREATE [ OR REPLACE | IF NOT EXISTS ] DYNAMIC TABLE dtname
-[ (column_list ) ]
-[PARTITIONED BY (column_name) ]
-[CLUSTERED BY (column_name)]
-[COMMENT view_comment]
-[PROPERTIES('data_lifecycle'='day_num')];
-[refreshOption]
-AS <query>;  
-
-refreshOption ::=
-    REFRESH 
-    [START WITH timestamp_expr]  [interval_time] VCLUSTER vcname
-```
-
-**必需参数**
-
-1. dtname: 指定动态表名称。
-2. AS query：动态表所包含的查询语句。
-
-**可选参数**
-
-1. IF NOT EXISTS:可选，如果指定的物化视图名字存在，系统不会报错，但是物化视图不会创建成功。不能和OR REPLACE同时使用
-
-2. OR REPLACE:在传统数据库中，此选项用于在同一个事务内用新对象替换旧对象，并删除旧对象的数据。但在Lakehouse中，为了支持动态表（Dynamic Table）的增加、删除和修改操作，我们保留了数据以及元数据权限信息。这意味着，即使在修改表结构或SQL逻辑时，原有数据也不会丢失。此功能特别适用于添加或删除列、调整SQL处理逻辑以及变更数据类型。需要注意的是如果用户不是简单的 删除列 / 添加列
-   添加列定义：只能是从表一路经由SELECT透传的，不能参与任何会影响其他列的计算例如 join key, group key 等。则在 Create Or Replace 发生后，REFRESH任务会退化为一次全量刷新
-
-   ```

-
-3. \<column\_list>：
-   * 可以指定列的名称或者向dynamic table的列添加注释信息，可以指定列的名称无法指定列的类型，类型由 `AS <query>`中的SELECT结果推断而来，如果您希望指定类型可以在SELECT结果中显示CAST转化
-   * 如果表中有任何列是基于表达式，建议为每列提供名称。或者as \<query>中使用别名
-   ```SQL
-     --指定列的comment，当有表达式时建议指定列名字
-   CREATE DYNAMIC TABLE change_table_dy (i, j_dd COMMENT 'test') AS
-   SELECT    i,
-             j + 1
-   FROM      dy_base_a;
-     +-------------+-----------+---------+
-     | column_name | data_type | comment |
-     +-------------+-----------+---------+
-     | i           | int       |         |
-     | j_dd        | int       | test    |
-     +-------------+-----------+---------+
-     --当存在列运算表达式使用别名方式
-   CREATE DYNAMIC TABLE change_table_dy AS
-   SELECT    i,
-             j + 1 AS j_add
-   FROM      dy_base_a;
-     +-------------+-----------+---------+
-     | column_name | data_type | comment |
-     +-------------+-----------+---------+
-     | i           | int       |         |
-     | j_add       | int       |         |
-     +-------------+-----------+---------+
-   ```
-
-4. partitioned by (\<col> ):指定分区，将\<column\_list>的列作为分区，分区是一种通过在写入时将相似的行分组在一起来加快查询速度的方法。使用分区可以达到数据裁剪，优化查询
-
-   ```SQL
-   CREATE DYNAMIC TABLE change_table_dy (i, j_dd COMMENT 'test') PARTITIONED BY (j_dd) AS
-   SELECT    i,
-             j + 1
-   FROM      dy_base_a;
-   ```
-
-4.CLUSTERED BY：可选，指定Hash Key。Lakehouse将对指定列进行Hash运算，将数据根据Hash值分散到各个数据分桶中。为了避免数据倾斜和热点，并提高并行执行效果，建议选择取值范围大、重复键值少的列作为Hash Key。通常在进行join操作时会有明显效果。建议在数据量大的场景下使用CLUSTERED BY，一般按照一个桶的大小在128MB到1GB之间。如果没有指定分桶，默认为256个buckets。
-
-* SORTED BY：可选，指定Bucket内字段的排序方式。建议SORTED BY和CLUSTERED BY保持一致，以获得更好的性能。当指定SORTED BY子句后，行数据将按照指定的列进行排序。
-  ```SQL
-  --创建分桶表
-  CREATE DYNAMIC TABLE change_table_dy (i, j_dd COMMENT 'test') 
-  CLUSTERED BY (j_dd) INTO 16 BUCKETS AS
-  SELECT    i,
-            j + 1
-  FROM      dy_base_a;
-  --创建分桶并指定排序
-  CREATE DYNAMIC TABLE change_table_dy
-  (i, j_dd COMMENT 'test')
-  CLUSTERED BY (j_dd) SORTED BY (j_dd)  INTO 16 BUCKETS  
-  AS
-  SELECT    i,
-            j + 1
-  FROM      dy_base_a;
-  ```
-
-5. comment:指定动态的注释信息
-
-6. refreshOption可选，刷新选项
-   * START WITH timestamp\_exp 指定开始时间，支持指定一个时间戳表达式，如果不写 START WITH 则从当前时间开始刷新
-     * `timestamp_expression`返回结果是一个标准的时间戳类型的表达式，TIMESTAMP AS OF指定的最早时间戳取决[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。如果未指定则使用当前时间戳的版本数据，例如：
-       \* `'2023-11-07 14:49:18'`，即可以强制转换为时间戳的字符串。
-       \* `cast('2023-11-07 14:49:18 Asia/Shanghai' as timestamp)`。
-       \* `current_timestamp() - interval '12' hours`。
-       \* 本身就是时间戳或可强制转换为时间戳的任何其他表达式。
-     ```
-     --指定第二天开始刷新,刷新时间间隔20个小时
-     CREATE DYNAMIC TABLE mydt (i, j)
-     REFRESH   START
-     WITH      current_timestamp() + INTERVAL '1' DAY INTERVAL '20' HOUR vcluster test_alter AS
-     SELECT    *
-     FROM      dy_base_a;
-     ```
-   * interval\_time指定时间间隔，支持[时间间隔类型interval](INTERVAL.md)，如果不写interval\_time，写了 START WITH 则只定时刷新一次START WITH 指定的时间。interval\_time时间间隔如下

-| INTERVAL '\[+ \| -]' SECOND         | 仅指定SECOND间隔                  | INTERVAL '59.999' SECOND表示59.999秒                         |
-| INTERVAL '\[+ \| -] ' DAY TO HOUR   | 同时指定DAY和HOUR间隔               | INTERVAL '1 23' DAY TO HOUR表示1天23小时                       |
-| INTERVAL '\[+ \| -] ' DAY TO MINUTE | 同时指定DAY、HOUR和MINUTE间隔        | INTERVAL '1 23:59' DAY TO MINUTE表示1天23小时59分钟              |
-| INTERVAL '\[+ \| -] ' DAY TO SECOND | 同时指定DAY、HOUR、MINUTE和SECOND间隔 | INTERVAL '1 23:59:59.999' DAY TO SECOND表示1天23小时59分59.999秒 |
-
-day：取值范围为\[0, 2147483647]。 hour：取值范围为\[0, 23]。minute：取值范围为\[0, 59]。second：取值范围为\[0, 59.999999999]。
-
-* INTERVAL最小值是1分钟，可以用 60 SECOND 或者1 MINUTE 来表示
-  * INTERVAL支持带引号或者不带引号，以下表示是等价的：
-    \*  INTERVAL "60 SECOND"
-    \*  INTERVAL ‘60 SECOND’
-    \* INTERVAL 60 SECOND
-  * INTERVAL支持的单位：SECOND，MINUTE，HOUR，DAY
-  * INTERVAL单位不区分大小写，HOUR、hour是等价的
-
-* 在 `refreshOption` 中指定计算集群。自动刷新会消耗资源，因此需要明确指定计算集群。如果未指定，将默认使用当前会话的计算集群。您可以通过 `SELECT current_vcluster()` 查看当前会话的计算集群。
-
-  * 建议使用GP型集群来刷新动态表。原因：动态表刷新过程中会根据内置策略自动执行小文件合并操作，而AP型集群不支持此功能。
-
-  ```SQL
-  CREATE DYNAMIC TABLE mydt (i, j)
-  REFRESH   interval '1' MINUTE vcluster test AS
-  SELECT    *
-  FROM      dy_base_a;
-  ```
-
-### 注意事项
-
-* 动态表的增量刷新是基于基表的历史版本。历史版本取决于[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。此参数定义了在被删除数据被保留的时间长度，Lakehouse默认保留数据一天。根据您的业务需求，您可以通过调整 `data_retention_days` 参数来延长或缩短数据的保留周期。请注意，调整数据保留周期可能会影响存储成本。延长保留周期会增加存储需求，从而可能增加相关的费用。
-
-# Dynamic Table 支持参数化定义
-
-Dynamic Table 支持参数化定义由两部分组成。
-
-* 创建分区动态表时参数定义SESSION\_CONFIGS()\['dt.args.event\_day']。用于写在SQL加工逻辑中，参数通过 SESSION\_CONFIGS()\['dt.args.xx'] 进行定义,表示查询源表。SESSION\_CONFIGS()是系统内置函数`'dt.args.xx'`：DT参数的名称，必须以`dt.args.`开头，以避免与系统内部字段冲突。表达的含义和传统调度中select \* from source\_table where pt=${bizdate}。`SESSION_CONFIGS()['dt.args.pt']`等价于`pt=${bizdate}`，SESSION\_CONFIGS()\['dt.args.xx'] 返回值类型为 String如果需要其它类型的参数，需要加一个CAST，例如 cast(SESSION\_CONFIGS()\['dt.args.xx'] as int)。如下案例：
-
-```sql
---源表
-CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
-
---定义动态表
-CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
-SELECT    col1,
-          nvl(col2, col1),
-          pt
-FROM      source_table
-WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
-```
-
-* 刷新时通过refresh dynamic table targe\_table partition(pt=${bizdate});指定分区值，其中pt=${bizdate}。对应于传统的insert ovewrite targe\_table partition(pt=${bizdate})
-
-```sql
---上面中定义的动态表分区字段是pt。因此刷新时传入pt=${bizdate}。这里假定bizdate是2024-11-13。刷新时应该使用如下语法
---将2024-11-13传入到创建语句时的SESSION_CONFIGS()['dt.args.pt']中，替换为2024-11-13用于过滤source_table中的数据
-SET dt.args.pt = 2024 -11 -13;
---刷新时指定pt=2024-11-13表示写入到动态表的2024-11-13分区中
-REFRESH   dynamic TABLE targe_table PARTITION (pt = '2024-11-13');
-```
-
-## 全量刷新与增量刷新
-
-### 全量刷新
-
-全量刷新发生在以下情况：
-
-1. **非分区表**：
-
-   * 如果在非分区表中使用了参数 `SESSION_CONFIGS()['dt.args.event_day']`，系统会根据参数值的变化决定刷新方式。
-   * 如果参数值保持不变，系统将执行**增量刷新**。
-   * 如果参数值发生变化，系统将执行**全量刷新**，因为参数值的变化等同于改变了表的定义。
-
-2. **分区表**：
-
-   * 分区存在，但是当前刷新的参数与上一次刷新的参数不相同，则进行一次全量刷新，因为参数值的变化会导致 SQL 加工逻辑发生变化。
-   * 如果分区不存在（即第一次刷新某个分区），则进行一次全量刷新
-
-```sql
--- 创建源表
-CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
-
--- 创建动态表
-CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
-SELECT    col1,
-          nvl(col2, col1),
-          pt
-FROM      source_table
-WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
-
--- 示例 1：首次设置参数值为 2024-11-14
-SET dt.args.xxx = 1;
-SET dt.args.pt =2024-11-14;
-
---刷新为全量刷新
-REFRESH   dynamic TABLE incremental_dt PARTITION (pt = '2024-11-14');
-
-
--- 示例 2：果第一次刷新某个分区，对应的参数是一个值，如果后面相同分区对应的参数发生了改变了，则相当于dt在这个分区的定义被修改了，所以会重新刷新，如下案例
-SET dt.args.xxx = 2;
-SET dt.args.pt = 2024-11-14;
--- 刷新动态表，指定分区 pt=2024-11-14
--- 系统会执行全量刷新，因为参数值发生了变化
-REFRESH   dynamic TABLE incremental_dt PARTITION (pt = '2024-11-14');
-```
-
-### 增量刷新
-
-增量刷新发生在以下情况：
-
-* 非分区表的参数值保持不变。
-* 分区表的参数值保持不变，且分区条件未改变。
-
-**示例代码**：
-
-```SQL
-
--- 创建源表
-CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
-
--- 定义动态表
-CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
-SELECT    col1,
-          nvl(col2, col1),
-          pt
-FROM      source_table
-WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
-
--- 示例 1：首次设置参数值为 2024-11-13
-SET dt.args.pt = 2024 -11 -13;
-
--- 刷新动态表，指定分区 pt=2024-11-13，全量刷新
-REFRESH   dynamic TABLE target_table PARTITION (pt = '2024-11-13');
-
--- 示例 2：参数值和分区值未变化，再次刷新
-SET dt.args.pt = 2024 -11 -13;
-
--- 刷新动态表，指定分区 pt=2024-11-13
--- 系统会继续执行增量刷新
-REFRESH   dynamic TABLE target_table PARTITION (pt = '2024-11-13');
-```
-
-## 刷新语句
-
-参数化定义的Dynamic Table的刷新行为取决于表是否为分区表。
-
-### **非分区表刷新语法**：
-
-```SQL
-REFRESH DYNAMIC TABLE dt;。
-```
-
-* 非分区表的参数值保持不变，会增量刷新。非分区表的参数值发生变化，会全量刷新
-
-### **分区表刷新语法**：
-
-```SQL
-REFRESH DYNAMIC TABLE dt PARTITION partition_spec;
-```
-
-语句刷新分区表时，必须按照表的分区层级顺序指定`partition_spec`。这意味着，如果表按照多个字段进行分区，这些字段需要按照从最高级别到最低级别的顺序被指定。
-
-* 多级分区，partition\_spec 需要根据分区的层级依次指定。例如，如果表有三级分区(day, hour, min)，必须从高到低依次指定，不能跳过某个分区。指定 day hour 是合法的，低级分区可以忽略，不用全声明。指定 day min 是不合法的，因为它跳过了 hour
-
-  * ```SQL
-    --不合法的
-    set dt.args.day = 1;
-    set dt.args.min = 1;
-    REFRESH   dynamic TABLE incremental_dt PARTITION (DAY = 1, MIN = 1);
-
-    --合法的
-    set dt.args.day = 1;
-     set dt.args.hour = 1;
-    REFRESH   dynamic TABLE incremental_dt PARTITION (DAY = 1, HOUR = 1);
-    ```
-
-**示例说明**：
-
-假设一个表按照`day`、`hour`和`min`三级进行分区，正确的`partition_spec`指定方式如下：
-
-* **合法指定**：您可以指定高层级和部分低层级分区，但不可跳过任何中间层级分区。
-
-```SQL
-set dt.args.day=2024-11-13;
-set dt.args.hour=23;
-REFRESH DYNAMIC TABLE dt PARTITION (day='2024-11-13', hour=23); 
-```
-
-在这个例子中，`day`和`hour`被指定，而`min`分区可以被忽略。
-
-* **不合法指定**：跳过任何中间层级分区的指定是不被允许的。
-
-```SQL
-set dt.args.day=2024-11-13
-set dt.args.hour=30
-REFRESH DYNAMIC TABLE dt PARTITION (day='2024-11-13', min=30); 
-```
-
-## **注意事项**
-
-* **参数与分区一致性**：在执行Dynamic Table的刷新操作时，必须确保证SQL计算的分区值与指定刷新的分区值保持一致。如果存在不一致，系统将在执行过程中报错。
-
-```SQL
-CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
-SELECT    col1,
-          nvl(col2, col1),
-          pt
-FROM      source_table
-WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
-
---比如select col1, nvl(col2, col1), pt from source_table where pt = SESSION_CONFIGS()['dt.args.pt'];过滤出来对应的分区字段结果是9.系统将在执行过程中报错，
-set dt.args.event_day = 9;
-
-REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 19);
-
-```
-
-* **并发刷新任务**：在这些命令中，参数值与分区值匹配，因此可以并发执行而不会发生冲突。只要分区之间不存在冲突，系统允许同时执行多个分区的刷新任务。
-
-```SQL
--- 为分区 event_day=19 设置参数并刷新
-set dt.args.event_day = 19;
-
-REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 19);
-
--- 为分区 event_day=20 设置参数并刷新
-set dt.args.event_day = 20;
-
-REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 20);
-```
-
-## 使用案例
-
-* 动态表分区字段和源表中字段一致
-
-```sql
-CREATE TABLE event_tb_pt (
-    event STRING,
-    process DOUBLE,
-    event_time TIMESTAMP
-  );
-INSERT INTO event_tb_pt VALUES
-  ('event-0', 20.0, TIMESTAMP '2024-09-20 14:43:13'),
-  ('event-0', 20.0, TIMESTAMP '2024-09-19 11:40:13'),
- ('event-1', 20.0, TIMESTAMP '2024-09-19 11:40:13');
---创建动态表
-CREATE dynamic table  event_gettime_pt 
-partitioned by(event)
-AS SELECT
-  event,
-  process,
-  YEAR(event_time) event_year,
-  MONTH(event_time) event_month,
-  DAY(event_time) event_day
-FROM event_tb_pt
-where event=SESSION_CONFIGS()['dt.args.event'];
---刷新动态表
-set dt.args.event = event-0;
-REFRESH   dynamic TABLE event_gettime_pt PARTITION (event = 'event-0');
-SELECT *FROM event_gettime_pt;
-```
-
-* 动态表分区字段和源表中字段名字不一致。过滤条件需要根据event过滤，动态表分区字段是event\_year
-
-```sql
-DROP      TABLE IF EXISTS event_tb_pt;
-CREATE TABLE event_tb_pt (
-    event STRING,
-    process DOUBLE,
-    event_time TIMESTAMP

-**案例一：将离线任务转换为增量任务**
-本节将指导用户如何将原有的离线任务转换为增量任务，以实现更高效的数据处理。以下是一个基于“传统数据库”的具体操作步骤，适用于业务逻辑按天对齐和按天调度刷新的场景。
-
-* 步骤 1：参数化原始 SQL。原始 SQL如下
-
-  ```sql
-  WITH      tmp_channel AS (
-            SELECT    channel_code,
-                      channel_name,
-                      channel_type,
-                      channel_uid
-            FROM      dim.dim_shop_sales_channel_main
-            WHERE     pt = '${bizdate}'
-            ),
-            tmp_bac_misc AS (
-            SELECT    mini_number,
-                      bac_no
-            FROM      dim.dim_customer_bac_misc_df
-            WHERE     pt = '${bizdate}'
-            ),
-            tmp_fxiaoke AS (
-            SELECT    CASE
-                                WHEN record_type IN ('dealer__c') THEN nvl(bac_no, account_no)
-                                ELSE account_no
-                      END AS channel_code,
-                      id,
-                      account_no
-            FROM      ods.ods_account_obj AS a
-            LEFT JOIN tmp_bac_misc ON a.account_no = tmp_bac_misc.mini_number
-            WHERE     pt = '${bizdate}' AND      
-                      account_no IS NOT NULL
-                      --  and is_deleted = 0
-                      --  and life_status not in ('invalid', 'ineffective')
-            )
-  INSERT    OVERWRITE TABLE dim.dim_shop_sales_channel_misc PARTITION (pt = '${bizdate}')
-  SELECT    tmp_channel.channel_code,
-            channel_name,
-            channel_type,
-            channel_uid,
-            id AS fxiaoke_id,
-            account_no AS fxiaoke_account_no
-  FROM      tmp_channel
-  LEFT JOIN tmp_fxiaoke ON tmp_channel.channel_code = tmp_fxiaoke.channel_code;
-  ```
-
-  首先，需要将原始 SQL 中的所有由调度引擎传入的参数 `${bizdate}` 替换为 `SESSION_CONFIGS()['dt.args.bizdate']`。这一步骤将使得参数值可以通过配置动态传入，而不是硬编码在 SQL 中。
-
-  **原始 SQL 参数替换**:
-  将所有 `${bizdate}` 替换为 `SESSION_CONFIGS()['dt.args.bizdate']`：
-
-  ```sql
-  CREATE dynamic TABLE im.dim_shop_sales_channel_misc
-  PARTITIONED BY (pt)
-  WITH      tmp_channel AS (
-            SELECT    channel_code,
-                      channel_name,
-                      channel_type,
-                      channel_uidfrom dim.dim_shop_sales_channel_main
-            WHERE     pt = SESSION_CONFIGS () ['dt.args.bizdate']
-            ),
-            tmp_bac_misc AS (
-            SELECT    mini_number,
-                      bac_nofrom dim.dim_customer_bac_misc_df
-            WHERE     pt = SESSION_CONFIGS () ['dt.args.bizdate']
-            ), 
-           tmp_fxiaoke AS (    
-            SELECT    CASE
-                                WHEN record_type IN ('dealer__c') THEN nvl(bac_no, account_no)
-                                ELSE account_no
-                      END AS channel_code,
-                      id,
-                      account_no
-            FROM      ods.ods_account_obj AS a
-            LEFT JOIN tmp_bac_misc ON a.account_no = tmp_bac_misc.mini_number
-      WHERE pt = SESSION_CONFIGS()['dt.args.bizdate'] and account_no is not null
-  )
-  SELECT    tmp_channel.channel_code,
-            channel_name,
-            channel_type,
-            channel_uid,
-            id AS fxiaoke_id,
-            account_no AS fxiaoke_account_no,
-            pt
-  FROM      tmp_channel
-  LEFT JOIN tmp_fxiaoke ON tmp_channel.channel_code = tmp_fxiaoke.channel_code
-  ;
-  ```
-
-* 步骤 2：调度刷新命令
-  在每次调度时，需要将参数 `dt.args.bizdate` 设置为具体的日期值，并执行刷新命令。
-
-  调度刷新命令示例
-
-  ```sql
-  SET dt.args.bizdate=20241130; -- ${bizdate}由Studio每次替换为具体的值
-  REFRESH DYNAMIC TABLE DT PARTITION (pt ='20241130');
-  ```
-
-**案例二：增量任务数据补数，在某些情况下，用户可能需要向已有的分区中补充数据**。
-
-* 方法 1：向源表补充数据，用户可以直接向源表中补充数据。这些补充的数据将通过相应的 REFRESH 任务自动反映到 Dynamic Table（DT）中。
-
-  操作步骤
-
-  1. 直接向源表插入或更新数据。
-  2. 执行 REFRESH 任务，以将更改同步到 DT 中。
-* 方法 2：使用 DML 语句直接向 DT 补充数据，用户也可以使用 DML 语句直接向 DT 的特定分区中插入数据。
-  操作步骤
-  1. 使用 DML 语句向 DT 的特定分区插入数据。
-  2. 请注意，直接修改 DT 将导致下一次该分区的全量刷新。如果用户不希望出现全量刷新的结果，应避免调度该分区的 REFRESH 任务。
-     示例代码
-  ```sql
-  INSERT INTO DYNAMIC TABLE incremental_dt VALUES (...);
-  ```
-
-**案例三：多表join**
-
-```

-
-**注意事项**
-
-* 直接向 DT 插入的数据将参与 DT 的下游计算。如果下游的老分区不需要这些数据，请不要调度涉及这些数据的分区的 REFRESH 任务。
-* 其他未受影响的分区仍然可以进行增量刷新。
-
-**案例三：在不同 VC 中执行增量任务，对于参数化声明的分区化 DT，不同分区的刷新任务可以同时执行。用户可以根据需要将不同的 REFRESH 任务分配到不同的虚拟集群（VC）中执行**。
-操作步骤
-
-1. 根据实效性要求和资源需求，将不同的 REFRESH 任务分配到不同的 VC 中。
-2. 例如，对于实效性要求较高的新分区，可以将其 REFRESH 任务放在资源较多的大 VC 中执行。
-3. 对于其他老分区的补充任务，可以将其 REFRESH 任务放在资源较少的小 VC 中执行。

-# 创建Hive External Catalog
-
-创建 Hive External Catalog 的步骤如下：
-
-1. [创建存储连接](create-storage-connection.md)：首先需要创建一个存储连接，用于访问对象存储服务。
-2. [创建 Catalog Connection](create-catalog-connection.md)：使用存储连接信息和 Hive Metastore 地址创建 Catalog Connection。
-3. 创建External Catalog：使用 Catalog Connection 创建外部 Catalog，以便在数据湖中访问外部数据。
-
-## 语法
-
-```SQL
-CREATE EXTERNAL CATALOG catalog_name
-    CONNECTION catalog_api_connection;
-```
-
-**参数说明**
-
-* **catalog_api_connection**：Catalog Connection 名称。目前只支持 HIVE。[参考创建catalog conneciton](create-catalog-connection.md)
-
-### 案例
-
-**案例一：Hive ON OSS（支持读取和写入）**
-
-* 创建存储连接
-
-```SQL
-CREATE STORAGE CONNECTION if not exists catalog_storage_oss   
- type OSS    
- ACCESS_ID='LTAIxxxxxxxxxxxx'    
- ACCESS_KEY='T8Gexxxxxxmtxxxxxx'   
- ENDPOINT='oss-cn-hangzhou-internal.aliyuncs.com';
-```
-
-* 创建 Catalog Connection
-  请确保 HMS 所在服务器网络与 Lakehouse 打通。具体打通方式可以参考[创建阿里云终端节点服务](creating_alicloud_privatelinkservice.md)
-
-```SQL
-CREATE CATALOG CONNECTION if not exists catalog_api_connection    
-type hms    
-hive_metastore_uris='xxxx:9083'    
-storage_connection='catalog_storage_oss';
-```
-
-* 创建 Catalog
-
-```SQL
-CREATE EXTERNAL CATALOG my_external_catalog
-    CONNECTION catalog_api_connection;
-```
-
-* 验证是否连通Hive Catalog
-
-```SQL
---验证读取元数据
-SHOW SCHEMAS IN my_external_catalog;
-+---------------------------------------------------------------------------+
-|                                schema_name                                |

-+---------------------------------------------------------------------------+
-
---验证读取数据，读取数据时会使用STORAGE CONNECTION权限读取
-SELECT * FROM my_external_catalog.my_schema.my_table;
-```
-
-**案例二：Hive ON COS（支持读取和写入）**
-
-* 创建存储连接
-
-```sql
-CREATE STORAGE CONNECTION catalog_storage_cos 
-  TYPE COS
-  ACCESS_KEY = '<access_key>'
-  SECRET_KEY = '<secret_key>'
-  REGION = 'ap-shanghai'
-  APP_ID = '1310000503';
-```
-
-**参数**：
-* **TYPE**：对象存储类型，腾讯云应填写 `COS`（大小写不限）。
-* **ACCESS_KEY / SECRET_KEY**：为腾讯云的访问密钥，获取方式参考：[访问密钥](https://cloud.tencent.com/document/product/598/40488)
-* **REGION**：指腾讯云对象存储 COS 的数据中心所在的地域。相同地域内云器Lakehouse访问腾讯云COS时，COS服务将自动路由至内网访问。具体取值请参考腾讯云文档：[地域和访问域名](https://cloud.tencent.com/document/product/436/6224)。
-
-* 创建 Catalog Connection
-  请确保 HMS 所在服务器网络与 Lakehouse 打通。具体打通方式可以参考[创建腾讯云终端节点服务](creating_tencentcloud_privatelinkservice.md)
-
-```SQL
-CREATE CATALOG CONNECTION if not exists catalog_api_connection

-## 功能概述
-
-在数据湖架构中，Hive Catalog 是一个关键组件，用于将数据湖与外部的元数据存储（例如 Hive Metastore）关联起来。通过创建 Hive Catalog，用户可以实现元数据的统一管理和访问，从而直接读取存储在外部系统中的数据。Apache Hive 已成为数据仓库生态系统的核心，不仅是大数据分析和 ETL 的 SQL 引擎，还是一个数据管理平台，可用于发现、定义和演化数据。同时，Lakehouse 支持读取和写入 Hive 数据。
-
-## 使用限制
-
-* 使用前请注意，需要保证 Lakehouse 和 Hive 集群网络连通。
-* 目前，云器 Lakehouse 的外部 Catalog 功能支持以下外部数据源：
-  * Hive on OSS（阿里云对象存储服务）
-  * Hive on COS（腾讯云对象存储服务）
-  * Hive on S3（AWS 对象存储服务）
-  * Hive on GCS（Google云对象存储服务）
-  * Hive on HDFS (Preview，请联系 Lakehouse 支持)
-* 同时支持读取和写入。写入格式支持 Parquet、ORC、Text 文件格式。
-
-### 创建外部 Catalog
-
-**创建 Hive Catalog 的步骤**
-
-1. **创建存储连接**：首先需要创建一个存储连接，用于访问对象存储服务。
-2. **创建 Catalog Connection**：使用存储连接信息和 Hive Metastore 地址创建 Catalog Connection。
-3. **创建外部 Catalog**：使用 Catalog Connection 创建外部 Catalog，以便在数据湖中访问外部数据。
-
-#### 创建存储连接
-
-创建存储连接可参考文档 [创建STORAGE CONNECTION](aliyun_storage_connection.md)。
-
-```SQL
-CREATE STORAGE CONNECTION if not exists catalog_storage_oss
-    type OSS
-    ACCESS_ID='LTAIxxxxxxxxxxxx'
-    ACCESS_KEY='T8Gexxxxxxmtxxxxxx'
-    ENDPOINT='oss-cn-hangzhou-internal.aliyuncs.com';
-```
-
-#### 创建 Catalog Connection
-
-```SQL
-CREATE CATALOG CONNECTION if not exists catalog_api_connection
-    type hms
-    hive_metastore_uris='xxx:9083'
-    storage_connection='catalog_storage_oss';
-```
-
-#### 创建外部 Catalog
-
-```SQL
-CREATE EXTERNAL CATALOG test_external_catalog
-    CONNECTION catalog_catalog_connection;
-```
-
-#### 使用 Catalog
-
-```SQL
---列出catalog下的schema
-show schemas in test_external_catalog;
---列出catalog下的所有表
-show tables in test_external_catalog.my_external_test;
---查寻catalog下的表
-select * from test_external_catalog.my_external_test.test;
---查看catalog下的表结构
-desc test_external_catalog.my_external_test.test;
-```
-
-#### 使用 Hive 表和 Lakehouse 表关联查询
-
-其中，`test_external_catalog.my_external_test.test` 是 Hive 中的表，`public.test` 是 Lakehouse 的内部表。
-
-```
-select * from 
-test_external_catalog.my_external_test.test a
-left join 
-public.test b 
-on a.id=b.id;
-```

-## 创建倒排索引
-
-具体介绍参考[倒排索引](inverted-index.md)介绍
-
-### 语法
-
-```SQL
-CREATE TABLE table_name(
-  columns_difinition,
-  INDEX index_name (column_name) INVERTED [COMMENT '']  PROPERTIES('analyzer'='english｜chinese|keyword｜unicode'),
-  INDEX index_name (column_name) INVERTED [COMMENT '']  PROPERTIES('analyzer'='english｜chinese|keyword｜unicode'),
-....
-  INDEX index_name (column_name) INVERTED [COMMENT '']  PROPERTIES('analyzer'='english｜chinese|keyword｜unicode')
-);
-```
-
-**columns\_difinition**:定义表的字段信息，最后一个字段必须使用逗号隔开
-
-**INDEX**：关键字
-
-**index\_name**：自定义index的名称
-
-**column\_name**：需要添加索引的字段名称
-
-**INVERTED**：关键字，表示倒排索引
-
-**COMMENT**：指定index的说明信息
-
-**PROPERTIES**：指定INDEX的参数，支持的属性目前支持指定分词。数值和日期类型则不需要指定properties，如果是字符串类型要求必须指定分词
-
-* 分词参数：'analyzer'='english｜chinese | keyword｜unicode'，用于指定文本分词的策略，适用于不同的语言和需求。
-  * **keyword**: 此类型的字段不会进行分词。整个字符串被视为单一的词根，并存储在倒排索引中。搜索时，需要提供完整的字段值以实现精确匹配。
-  * **english**: 专为英文设计的分词器，仅识别连续的ASCII字母和数字，并将文本统一转换为小写。适合处理英文内容，忽略非字母数字字符。
-  * **chinese**: 中文文本分词插件，识别中文和英文字符，同时过滤掉标点符号，并将英文字母转换为小写。适用于中英文混合文本的处理。
-  * **unicode**: 基于Unicode文本分割算法的分词器，能够识别多种语言的文本边界，有效将文本分割成单词，并将字母转换为小写。适合多语言环境下的文本处理。

-# 创建DELTA和HUDI外部表
-
-## 功能
-
-外部表功能允许Lakehouse查询和分析存储在对象存储等外部存储系统中的数据。用户可以直接操作外部数据，而无需将数据导入Lakehouse内部存储，这提供了数据处理的灵活性和便利性。
-
-**外部表的其他命令**：
-
-* **删除外部表**：通过使用`DROP TABLE`语法，删除外部表。
-* **查看外部表详情**：使用`DESC TABLE`语法，您可以快速查看外部表的结构和详细信息。
-* **修改外部表**：修改外部表，`ALTER TABLE`
-* **查看外部表建表语句**：`SHOW CREATE TABLE`语句
-* **参考案例**: 具体如何操作外部表，可以参考[Delta Lake](delta-lake.md)的外部表使用指南。
-
-## 支持的范围
-
-* 支持阿里云对象存储oss、支持腾讯云对象存储cos、支持Aws对象存储S3
-
-## **语法**
-
-```SQL
-CREATE EXTERNAL TABLE [ IF NOT EXISTS ] table_name
-[(
-  column_definition [, column_definition, ...]
-)]
-[PARTITIONED BY (col_name col_type [, col_name col_type, ...] )]
-USING DELTA|HUDI
-CONNECTION connection_name
-LOCATION 'file_path'
-[COMMENT 'table_comment']
-```
-
-## **参数说明**
-
-**必选参数**:
-
-* `CREATE EXTERNAL TABLE`: 声明创建一个外部表。
-
-* `table_name`: 外部表的名称。
-
-* `column_definition`: 列定义，指定列的名称和数据类型。要求必须和delta、hudi中的类型和名称保持一致。参考Lakehouse支持的[数据类型](data-type.md)。可选，Lakehouse支持自动推断列的名称和数据类型
-
-* `USING DELTA|HUDI`: 指定文件格式目前支持Delta Lake和Hudi格式
-
-* `CONNECTION connection_name`: 连接外部数据源的认证信息，`connection_name`是Lakehouse中定义的连接对象名称。用于认证连接信息，连接对象存储。具体创建文档参考[对象存储连接(STORAGE CONNECTION)](Datalake_StorageConnection.md)
-  * 创建oss connection
-  ```
-  CREATE STORAGE CONNECTION my_conn 
-    TYPE COS
-    ACCESS_KEY = '<access_key>'
-    SECRET_KEY = '<secret_key>'
-    REGION = 'ap-shanghai'
-    APP_ID = '1310000503';
-  ```
-  * 创建cos connection
-  ```
-  CREATE STORAGE CONNECTION my_conn 
-    TYPE COS
-    ACCESS_KEY = '<access_key>'
-    SECRET_KEY = '<secret_key>'
-    REGION = 'ap-shanghai'
-    APP_ID = '1310000503';
-  ```
-  * 创建s3 connection
-  ```
-  CREATE STORAGE CONNECTION aws_bj_conn
-      TYPE S3
-      ACCESS_KEY = 'AKIAQNBSBP6EIJE33***'
-      SECRET_KEY = '7kfheDrmq***************************'
-      ENDPOINT = 's3.cn-north-1.amazonaws.com.cn'
-      REGION = 'cn-north-1';
-  ```
-
-* `LOCATION 'file_path'`: 使用 `LOCATION 'file_path'` 指令可指定待读取的数据文件路径，支持多种云存储格式。对于 Delta Lake 表，外部表将扫描该位置中的事务日志文件（如 `_delta_log/00000000000000000000.json` 或 `_delta_log/00000000000000000010.checkpoint.parquet`），以确定最新的 Parquet 文件。
-  * file\_path 是一个区分大小写的字符串，代表云存储中文件的位置或前缀（即文件夹），用于限定要加载的文件集。腾讯云对象存储 (COS): cos\://bucketname/path、阿里云对象存储 (OSS): oss//bucketname/path、AWS S3 对象存储: s3://bucketname/path
-
-  * file\_path中指定的路径必须仅包含单个 Delta Lake 或 Hudi 表的数据文件和元数据。即，每个存储位置只能对应一个目录。
-
-  * file\_path读取数据时会使用connection中的权限和认证信息。需要授权GetObject、ListObjects、PutObject、DeleteObject权限
-
-  * 每次读取时都会重新解析 Delta Lake 事务日志，确保获取最新的元数据。因此，不会缓存元数据。
-
-**可选参数**:
-
-* `IF NOT EXISTS`: 如果外部表不存在，则创建它；如果已存在，则不执行任何操作。
-* `PARTITIONED BY (col_name col_type [, col_name col_type, ...])`: 指定分区列及其数据类型，用于数据分区。如果DELTA和HUID是分区表则必须指定
-* `COMMENT 'table_comment'`: 为外部表提供描述性注释。
-
-## 用法说明
-
-* 外部表无法访问归档类型的文件，这些数据需要先还原才能检索
-* 外部表不支持TIME TRAVEL.
-* 删除外部表时只会删除外部表的定义，不会删除对象存储中的文件
-

-# CREATE SCHEMA FROM SHARE
-
-## 功能
-
-`CREATE SCHEMA FROM SHARE` 语句用于使用被分享数据。该语句以 schema 为单位提取指定 share 对象中包含的数据对象，以便在数仓中对这些数据进行查询或处理。
-
-## 语法
-
-```SQL
-CREATE SCHEMA <new_schema_name> FROM SHARE SHARE <instance_name>.<share_name>.<schema_name> ;
-```
-
-## 参数说明
-
-**new_schema_name**: 基于 share 中的数据创建在本地数仓中的 schema 名称；注意该 schema 不可与工作空间中其他 schema 重名，且该 schema 创建后为只读 schema，不可在其中创建其他数据对象。
-
-**instance_name.share_name**: 被提取的 share 名称。因不同服务实例可能共享同名的 share 对象，所以需要在 share 名称前加上 instance 名称以准确标识一个唯一的 share 对象。该信息可以通过具备实例管理员（instance\_admin）或工作空间管理员（workspace\_admin）角色的用户，执行`show shares；` 语句来获取。
-
-![](.topwrite/assets/image_1741002148136.png)
-
-**schema_name**: 指需要被提取的数据。提取数据是以 schema 为单位的，语句执行后 new_schema_name 中所包含的数据对象（table、view 等）与 share 中 schema_name 下所包含的数据对象一致。所以这里需要填入要提取的 share 中的 schema_name。
-
-该信息可以通过具备实例管理员（instance\_admin）或工作空间管理员（workspace\_admin）角色的用户，执行`desc share <instace_name>.<share_name>；` 语句来获取。一个share对象中可能包含多个schema，使用需要提取的schema的名称。

-# CREATE SQL FUNCTION
-
-## 概述
-
-`CREATE FUNCTION` 语句用于在 Lakehouse 中创建 SQL 标量函数或表函数。这些函数可以接受一组参数，并返回标量值或一组行。本文将详细介绍其语法、参数、使用示例。
-
-## 语法
-
-```sql
-CREATE [OR REPLACE] FUNCTION [IF NOT EXISTS]
-    function_name ( [ function_parameter [, ...] ] )
-     [ RETURNS data_type | RETURNS TABLE(column_spec)]
-   AS|RETURN { expression | query };
-
-function_parameter
-    parameter_name data_type ;
-
-column_spec
-    column_name data_type ;
-```
-
-## 参数说明
-
-* `OR REPLACE`
-  * 如果指定此参数，将替换具有相同名称和签名（参数数量和类型）的现有函数。
-  * 不能与 `IF NOT EXISTS` 同时使用。
-* `IF NOT EXISTS`:如果指定，仅在函数不存在时才会创建。
-* `function_name`:函数的名称，可以使用schema名称限定。
-* `function_parameter`
-  * `parameter_name`：参数名称必须在函数中唯一。
-  * `data_type`：支持的任何数据类型。
-* `RETURNS data_type`
-  * 标量函数的返回数据类型。如果未提供数据类型，将从函数体派生。
-* `RETURNS TABLE`：定义返回表结构，需指定列名和数据类型
-* `AS|RETURN {expression | query}`
-  * 函数的主体。对于标量函数，可以是表达式或查询；对于表函数，只能是查询。
-
-
-## 示例
-
-* 创建和使用 SQL 标量函数
-
-```sql
--- 创建一个函数,指定返回值
-CREATE FUNCTION public.area(x DOUBLE, y DOUBLE) 
-RETURNS DOUBLE
-RETURN x * y;
--- 在查询中使用函数
-SELECT public.area(3, 4);
--- 输出：12.0
-
--- 创建一个函数,使用AS指定处理逻辑
-CREATE FUNCTION public.area2(x DOUBLE, y DOUBLE)
-RETURNS double
-AS x * y;
-SELECT public.area2(3, 4);
-
-```
-
-* 指定返回类型
-
-```
-CREATE  FUNCTION public.hello()
-RETURNS STRING
-AS  'Hello World!';
-SELECT public.hello();
-```
-
-* 在expression使用内置函数
-
-```sql
-CREATE FUNCTION public.roll_dice(num_dice INT  ,
-                          num_sides INT   )
-RETURNS INT
-COMMENT 'Roll a number of n-sided dice'
-RETURN (rand() * num_sides)::INT + 1;
-SELECT public.roll_dice(3, 10);
-```
-
-* 返回一个返回表类型
-
-```
-CREATE TABLE employee (
-    id INT,
-    name STRING,
-    deptno INT
-);
-INSERT INTO employee (id, name, deptno)
-VALUES
-    (1, 'Alice', 10),
-    (2, 'Bob', 10),
-    (3, 'Charlie', 20),
-    (4, 'David', 10),
-    (5, 'Eve', 20);
-CREATE OR REPLACE FUNCTION ga1_1.getemps(deptno INT)
-    RETURNS TABLE (name STRING)
-    RETURN SELECT name FROM employee e WHERE e.deptno = deptno;
-SELECT * FROM ga1_1.getemps(10);
-```
-
-## 注意事项
-
-* 使用函数时必须指定创建时函数所在的Schema否则会错函数找不到。
-  您可以通过设置参数来cz.sql.remote.udf.lookup.policy避免报错。该参数是。动态切换 UDF 与内置函数的解析优先级。默认行为，使用UDF时必须带SCHEMA前缀，如下案例
-  ```
-  --创建函数
-  CREATE FUNCTION public.lower()
-  RETURNS STRING
-  AS 'Hello World!';
-  --使用函数，必须写SCHMA否则会报错函数找不到
-  SELECT public.lower();
-  -- 策略1：优先调用内置函数,可以不用写SCHMA。如果和内置函数同名优先使用内置函数
-  SET cz.sql.remote.udf.lookup.policy = builtin_first;
-  SELECT lower();
-  -- 策略2：优先调用UDF（适配MC/Spark作业场景）。如果和内置函数同名优先使用udf
-  SET cz.sql.remote.udf.lookup.policy = udf_first;
-  SELECT lower();
-  ```

-Storage Connection 主要用于存储第三方存储服务的身份认证信息，使 Lakehouse 能够安全地访问和管理这些存储服务中的数据。
-
-* 目前支持对象存储、Kafka、HDFS。其中对象存储包括腾讯云COS、阿里云OSS和AWS S3。
-* 目前不支持跨云厂商创建。比如您的 Lakehouse 实例运行在阿里云上，无法访问腾讯云的 COS 数据。
-
-## 创建阿里云存储连接
-
-本步骤的目标是：允许 Lakehouse 实例通过 VOLUME 对象，处理阿里云对象存储 OSS 中的数据。为了完成这个目标，可以通过阿里云提供的两种身份认证方式：**访问密钥** 和 **角色授权**。

-仅需提供带有访问 OSS 权限的账号的 AccessKey ID 和 AccessKey Secret 信息，利用这些信息创建存储连接 (Storage Connection) 对象，示例如下：
-
-```
-CREATE STORAGE CONNECTION if not exists hz_conn_ak
-    TYPE oss
-    ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com'
-    ACCESS_ID = 'LTAI5tMmbq1Ty1xxxxxxxxx'
-    ACCESS_KEY = '0d7Ap1VBuFTzNg7gxxxxxxxxxxxx';
-```
-
-### 基于角色授权方式（RoleARN）
-
-需要创建一个角色和权限策略：权限策略代表OSS 服务的访问策略，将这个策略授权给创建的角色。
-
-**以下主要讲述角色授权方式 (RoleARN) 的具体操作步骤**：
-
-1. 阿里云侧操作：在阿里云 RAM 控制台中创建权限策略 (CzUdfOssAccess)：注意：需要用户具有 RAM 权限
-
-* 访问阿里云访问控制（RAM）产品控制台
-* 左侧导航栏 **权限管理** -> **权限策略**，在权限策略界面选择 **创建权限策略**
-* 在**创建权限策略**页面选择 **脚本编辑** 页签，将下面`  [bucket_name_1|2|3]  `替换为实际的 OSS bucket 名称。注意：按照阿里云OSS 的约定，相同的 bucket 需要有两条 Resource 条目：`"acs:oss:*:*:bucket_name_1" `与 `"acs:oss:*:*:bucket_name_1/*"`同时存在才能达到授权效果：
-
-```JSON
-{
-    "Version": "1",
-    "Statement": [
-        {
-            "Effect": "Allow",
-            "Action": [
-                "oss:GetObject",
-                "oss:ListObjects",
-                "oss:PutObject",
-                "oss:DeleteObject"
-            ],
-            "Resource": [
-                "acs:oss:*:*:bucket_name_1",
-                "acs:oss:*:*:bucket_name_1/*",
-                "acs:oss:*:*:bucket_name_2",
-                "acs:oss:*:*:bucket_name_2/*",
-                "acs:oss:*:*:bucket_name_3",
-                "acs:oss:*:*:bucket_name_3/*"
-            ]
-        }
-    ]
-}
-```
-
-![](.topwrite/assets/OSS_P.jpeg)
-
-^
-
-2. 阿里云侧：在阿里云 RAM 中创建角色CzUDFRole：
-
-* 在阿里云访问控制（RAM）控制台左侧导航栏 **身份管理** -> **角色**，点击 **创建角色**
-
-* 在 **创建角色** 页面中，选择类型为 **阿里云账号**，在 **配置角色** 中填写自定义角色名称（如 CzUDFRole），在 **选择信任的云账号** 中选择 **其他云账号**，并填入账号 ID：1384322691904283，点击 **完成**。
-
-* 创建完成之后，点击**为角色授权**: 在**自定义策略**中，将刚创建的策略（CzUdfOssAccess）授权给该角色。在角色 CzUDFRole 详情页中，获取该角色的 RoleARN 信息：`'acs:ram::1222808864xxxxxxx:role/czudfrole'`
-
-![](.topwrite/assets/20231113-153016.jpeg)
-
-3. Lakehouse 侧：创建 Connection
-
-* 在 Studio 或者 Lakehouse JDBC 客户端中执行以下命令：
-
-```SQL
-CREATE STORAGE CONNECTION hz_oss_conn_rolearn 
-    TYPE oss 
-    REGION = 'cn-hangzhou' 
-    ROLE_ARN = 'acs:ram::1222808864467016:role/czudfrole' 
-    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com';
-```
-
-* 执行 `desc connection` 获取 `external ID `信息：本实例中，external ID 为：`O0lQUogDJajHqnAQ`
-
-> 为了防止 ROLE\_ARN 被第三方获取进行未授权的数据访问，可以使用` EXTENRAL ID` 作为一种额外的验证层，确保只有当请求中包含了预设的 `EXTERNAL ID` 时，这一访问才会被允许。这意味着即使第三方知道了其他一些访问信息（如角色ARN），没有正确的 `EXTERNAL ID` 也无法访问资源。
-
-![](.topwrite/assets/bloygC9Z6Q.jpg)
-
-4. 客户侧：在阿里云 RAM -> 角色->  信任策略中，修改 CzUDFRole 的**信任策略**：`"sts:ExternalId" `部分
-
-^
-
-```Python
-{
-  "Statement": [
-    {
-      "Action": "sts:AssumeRole",
-      "Condition": {
-        "StringEquals": {
-          "sts:ExternalId": "O0lQUogDJajHqnAQ"
-        }
-      },
-      "Effect": "Allow",
-      "Principal": {
-        "RAM": [
-          "acs:ram::1384322691904283:root"
-        ]
-      }
-    }
-  ],
-  "Version": "1"
-}

-## 创建腾讯云存储连接
-
-本步骤的目标是：允许 Lakehouse 集群访问腾讯云上的对象存储 COS。为了完成这个目标，可以通过腾讯云**访问管理**提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
-
-### 基于AK密钥方式
-
-```sql
-CREATE STORAGE CONNECTION my_conn 
-  TYPE COS
-  ACCESS_KEY = '<access_key>'
-  SECRET_KEY = '<secret_key>'
-  REGION = 'ap-shanghai'
-  APP_ID = '1310000503';
-```
-
-**参数**：
-
-* **TYPE**：为对象存储类型，腾讯云应填写 `COS`（大小写不限）
-
-* **ACCESS\_KEY / SECRET\_KEY**：为腾讯云的访问密钥，获取方式参考：[访问密钥](https://cloud.tencent.com/document/product/598/40488)
-
-* **REGION**：指腾讯云对象存储 COS 的数据中心所在的地域。相同地域内云器 Lakehouse 访问腾讯云 COS 时，COS服务将自动路由至内网访问。具体取值请参考腾讯云文档：[地域和访问域名](https://cloud.tencent.com/document/product/436/6224)。
-
-* **APP\_ID**：腾讯云存储桶的命名由存储桶名称（BucketName）和 APPID 两部分组成，两者以中划线“-”相连。例如 `examplebucket-1310000503`，其中 `examplebucket` 为用户自定义，`1310000503` 为系统生成数字串（APPID）。
-
-### 基于角色授权
-
-STEP1: 创建权限策略 (LakehouseAccess)：
-
-* 登录腾讯云，进入**访问管理**产品控制台
-* 在**访问管理**页面左侧导航栏进入**策略**，在权限控制界面选择 **新建自定义策略** -> **按策略生成器创建** -> **可视化策略生成器**。
-* 在**可视化策略生成器**页签中：**服务**（**Service**）: 选择 **对象存储(cos**)；**操作（Action）**：选择 **全部操作**（可根据实际需要的操作，做更细粒度的选择）；**资源（Resource**）：根据需要选择**全部资源**或者**特定资源**。本示例中选择特定资源，为上海区的` cz-volume-sh-1311343935`![](.topwrite/assets/20240625-211734.jpeg)
-* 点击**下一步**，填写**策略名称**为 LakehouseAccess 和描述后，点击**完成**
-
-STEP2：客户侧创建角色（LakehouseRole）
-
-* 进入腾讯云**访问管理**产品控制台
-* 在**访问管理**页面左侧导航栏进入**角色** -> **新建角色** -> **腾讯云账户**， 选择**其他主账号**，在 **账号ID** 中输入 `100029595716`（云器的腾讯云主账号），其它选项保持默认，点击**下一步**
-* 在**配置角色策略**配置中，将刚才新建的 LakehouseAccess 自定义策略授权给当前角色。点击 **下一步**，在**角色命名**中填写 `LakehouseRole `完成创建。
-* 创建成功后，在角色列表中，进入角色 `LakehouseRole` 的详情页，获取该角色的 RoleARN 信息：  `qcs::cam::uin/1000*******:roleName/LakehouseRole`
-
-STEP3：Lakehouse 侧创建 Connection
-
-* 在 Studio 或者 Lakehouse JDBC 客户端中执行以下命令：
-
-```
-CREATE STORAGE CONNECTION my_tx_connection_arn
-   TYPE cos
-   REGION = 'ap-shanghai'
-   ROLE_ARN = 'qcs::cam::uin/1000********:roleName/LakehouseRole'
-   APP_ID = '131****35';
-```
-
-* 注意：为了防止 ROLE\_ARN 被第三方获取进行未授权的数据访问，可以使用` EXTENRAL ID` 作为一种额外的验证层，确保只有当请求中包含了预设的 `EXTERNAL ID` 时，这一访问才会被允许。这意味着即使第三方知道了其他一些访问信息（如角色ARN），没有正确的 `EXTERNAL ID` 也无法访问资源。
-* 在创建存储连接的过程中，Lakehouse 会生成此EXTERNAL ID，可以将此EXTERNAL ID 配置到 COS 账号的角色校验中实现访问控制：
-
-```
--- 查看 EXTERNAL ID 
-DESC CONNECITON my_tx_connection_arn ;
-```
-
-![](.topwrite/assets/20240625-214538.jpeg)
-
-* 客户侧：进入腾讯云**访问管理**控制台中，**角色** -> **LakehouseRole** -> **角色载体**-> **管理载体**，选择 **添加账户** -> 选择**当前主账号**，并填写主账号ID：`100029595716`（云器的腾讯云主账号），并勾选**开启校验**，输入刚才 DESC 结果中的 EXTERNAL\_ID，点击 **确定**-> **更新**
-
-## 创建亚马逊云存储连接
-
-本步骤的目标是：允许 Lakehouse 集群访问亚马逊云 (AWS) 的对象存储 S3。为了完成这个目标，可以通过 AWS 的 **身份与访问管理 (IAM)** 产品提供的两种身份认证方式：**访问密钥** 和 **角色授权**。
-
-### 基于访问密钥
-
-```
-CREATE STORAGE CONNECTION aws_bj_conn
-    TYPE S3
-    ACCESS_KEY = 'AKIAQNBSBP6EIJE33***'
-    SECRET_KEY = '7kfheDrmq***************************'
-    ENDPOINT = 's3.cn-north-1.amazonaws.com.cn'
-    REGION = 'cn-north-1';
-```
-
-**参数**：
-
-* TYPE：为对象存储类型，AWS 应填写 S3（大小写不限）
-* ACCESS\_KEY / SECRET\_KEY：为AWS 的访问密钥，获取方式参考：[访问密钥](https://docs.aws.amazon.com/zh_cn/IAM/latest/UserGuide/id_credentials_access-keys.html)
-* ENDPOINT:  S3 的服务地址，AWS 中国区分为北京区和宁夏区，北京区的S3 的服务地址为 `s3.cn-north-1.amazonaws.com.cn`， 宁夏区 `s3.cn-northwest-1.amazonaws.com.cn`，可参考：[中国区终端节点](https://docs.amazonaws.cn/aws/latest/userguide/endpoints-arns.html) 分别找到北京区域和宁夏区域的终端节点 -> Amazon S3 对应的终端节点
-* REGION：AWS 中国区分为北京区和宁夏区，区域值为：北京区 `cn-north-1`， 宁夏区 `cn-northwest-1`，可参考：[中国区终端节点](https://docs.amazonaws.cn/aws/latest/userguide/endpoints-arns.html)
-
-### 基于角色授权
-
-需要在目标云对象存储 S3 所属的账号，在 IAM 中创建一个**权限策略**和**角色**：权限策略代表访问AWS S3 数据的规则，将这个策略授权给创建的角色。云器 Lakehouse 通过扮演这个角色来实现与 S3 中数据的读写操作。
-
-STEP1: AWS侧创建权限策略 (LakehouseAccess )：
-
-* 登录AWS 云平台，进入**身份与访问管理(IAM**) 产品控制台
-* 在 IAM 页面左侧导航栏进入 **账户设置**，在 **Security Token Service (STS)** 区域的 **终端节点** 列表中，找到当前实例对应云器Lakehouse 的区域，如果 **STS 状态** 为“未开启”，请将其开启。
-* 在 IAM 页面左侧导航栏进入 **策略**，在 **策略** 界面选择 **创建策略**，在策略编辑器中选择 JSON 方式
-* 将要添加允许云器Lakehouse 访问 S3 bucket 和目录的策略。下面是策略的样例，请用实际的bucket 和路径前缀名称替换 `<bucket>` 和 `<perfix>` 名称
-* **注意**：请将 `"s3:prefix" `项中填写:  `["*"]` or `["<path>/*"]` 分别代表授予对指定 bucket 或 bucket 中路径中的所有前缀的访问权限。

-
-* 点击 **下一步**，输入策略名称（如 LakehouseAccess）和描述（选填）
-* 点击创建策略完成策略创建
-
-STEP2: AWS侧创建角色 (LakehouseVolumeRole)：
-
-* 登录AWS 云平台，进入**身份与访问管理(IAM**) 产品控制台
-* 在 IAM 页面左侧导航栏进入**角色** -> **创建角色** -> **AWS账户**，选择 **另一个AWS账户**，在 Account ID 输入 `028022243208`
-
-> 注意：为了防止 ROLE\_ARN 被第三方获取进行未授权的数据访问，可以勾选 **选项** 中的 **需要外部 ID（第三方担任此角色时的最佳实践）**，勾选之后 **EXTENRAL ID** 项可以填写 `000000` 占位符稍后填充。`EXTERNAL ID` 作为一种额外的验证层，确保只有当请求中包含了预设的 `EXTERNAL ID` 时，这一访问才会被允许。这意味着即使第三方知道了其他一些访问信息（如角色ARN），没有正确的 `EXTERNAL ID` 也无法访问资源。

-CREATE STORAGE CONNECTION aws_bj_conn_arn
-  TYPE S3
-  REGION = 'cn-north-1'
-  ROLE_ARN = 'arn:aws-cn:iam::02802*******:role/LakehouseVolumeRole';
-```
-
-* 在创建存储连接的过程中，Lakehouse 会生成此EXTERNAL ID，可以将此EXTERNAL ID 配置到 STEP2创建的 AWS IAM 角色（`LakehouseVolumeRole`）的 Trust Policy 中，实现附加的访问控制：
-
-```
--- 查看 EXTERNAL ID 
-DESC CONNECITON aws_bj_conn_arn ;
-```
-
-![](.topwrite/assets/20240626-215920.jpeg)
-
-* 在AWS IAM 的控制台，左侧导航栏中进入角色 **Roles**，找到 STEP2 中创建的角色并进入角色详情页面，在 **Trust relationships** 中将 `sts:ExternalId `的值`  000000  `替换为 DESC 结果中的` EXTERNAL_ID`。点击**更新** 完成角色策略更新。
-
-## 创建Kafka存储连接
-
-Kafka连接主要是用于Kafka外部表，可以方便地从 Kafka 中读取数据流，并将这些数据流作为表进行查询和分析。
-
-### 语法
-
-```SQL
-CREATE STORAGE CONNECTION connection_name
-    TYPE kafka
-    BOOTSTRAP_SERVERS = ['server1:port1', 'server2:port2', ...]

-HDFS 连接主要用于 Lakehouse 联邦查询，可以方便地读取 HDFS 中的数据。
-
-### 语法
-
-```SQL
-CREATE STORAGE CONNECTION <connection_name> TYPE HDFSNAME_NODE='<nameservice_id>'NAME_NODE_RPC_ADDRESSES=['<rpc_address>']
-```
-
-### 参数说明
-
-* `<connection_name>` ：自定义的连接名称，用于标识该 HDFS 连接，例如`hdfs_conn`。
-* `TYPE HDFS` ：指定连接类型为 HDFS。
-* `NAME_NODE` ：对应 [HDFS 配置](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HDFSHighAvailabilityWithNFS.html)中的`dfs.nameservices`，是 HDFS 集群的逻辑名称，例如`zetta-cluster`。
-* `NAME_NODE_RPC_ADDRESSES` ：对应 [HDFS 配置](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HDFSHighAvailabilityWithNFS.html)中的`dfs.namenode.rpc-address`，是 NameNode 的 RPC 地址，格式为`[<host>:<port>]`，例如`['11.110.239.148:8020']`。

-## 功能
-
-创建同义词，同义词synonym是一个数据库对象，类似给对象起一个别名。支持为以下对象创建同义词：table、table stream、dynamic table、materialzied view、volume、function。
-
-## 创建语法
-
-```SQL
-CREATE  [TABLE|VOLUME|FUNCTION] SYNONYM [schema_name.] synonym_name FOR object COMMENT''
-object ::=
-workspace_name.schema_name.object_name|schema_name.object_name|object_name
-```
-
-* TABLE|VOLUME|FUNCTION：表示给哪种对象命名同义词，
-
-  * **TABLE**：这是默认选项。用于为table、table stream、materialzied view、dynamic table命名同义词。在这些情况下，“table”关键字是可选的。
-  * **VOLUME**：volume命名同义词时，必须明确指定此关键字。如果省略，系统将默认寻找同名的表格对象。
-  * **FUNCTION**：function命名同义词时，此关键字是必填项。如果未指定，系统同样会默认寻找同名的table对象
-
-* synonym\_name:同义词名称，遵循元数据规范
-
-* object：指定基对象的名称，支持workspace\_name.schema\_name\_2.object\_name、schema\_name\_2.name格式如果省略schema则使用当前schema中的对象
-
-### 权限
-
-* 创建create synonym需要create synonym权限
-
-```SQL
-grant create synonym  on schema  scname to user uat_test_01;
-```
-
-### 使用方式
-
-1. 具体使用方式参考[同义词使用](synonym.md)
-2. 当删除同义词引用（例如 TABLE、TABLE STREAM、MATERIALIZED VIEW、DYNAMIC TABLE、VOLUME、FUNCTION 等）后，如果随后创建了与之前同名的新引用，则系统将自动指向并使用新的引用。这意味着任何对原对象的引用，在新对象创建后，都将自动适用于新对象，而无需更改现有的查询或代码。
-
-## 使用案例
-
-案例一：给表创建同义词
-
-```SQL
-CREATE TABLE employees(id int,name string,skills array<string>);
-INSERT INTO employees (id, name, skills) VALUES
-(1, 'John Doe', ['Java', 'Python', 'SQL']),
-(2, 'Jane Smith', ['C++', 'Hadoop', 'SQL']),
-(3, 'Bob Johnson', ['Python', 'Docker']);
-CREATE TABLE SYNONYM employees_syno FOR employees;
---查询同义词
-SELECT * FROM employees_syno;
-+----+-------------+-------------------------+
-| id |    name     |         skills          |
-+----+-------------+-------------------------+
-| 1  | John Doe    | ["Java","Python","SQL"] |
-| 2  | Jane Smith  | ["C++","Hadoop","SQL"]  |
-| 3  | Bob Johnson | ["Python","Docker"]     |
-+----+-------------+-------------------------+
-
-```
-
-案例二：给table stream创建同义词，table stream和table创建同义词语法相同
-
-```SQL
-CREATE  SYNONYM employees_stream_synonym FOR public.employees_stream;
---删除同义词
-DROP SYNONYM employees_stream_synonym;
-```
-
-案例三：给DYNAMIC TABLE创建同义词，DYNAMIC TABLE和TABLE创建同义词语法相同
-
-```
-CREATE  SYNONYM dt_synonym for public.my_dt;
---删除同义词
-DROP SYNONYM dt_synonym;

-* **主键（PRIMARY KEY**） 用于确保表中每条记录的唯一性。在大数据场景下，由于数据量通常非常庞大，为了保证数据的唯一性而对所有 key 进行逐一检查是不现实且低效的，因此一般不推荐在大数据环境中使用主键约束。然而，Lakehouse 仍提供了对主键的支持，以便在特定场景下满足数据完整性的需求。在Lakehouse架构中，定义了主键的表在进行实时数据写入时，系统将自动根据主键值进行数据去重，这对于变更数据捕获（CDC）场景尤为重要。例如，您可以实时地将MySQL数据库的binlog日志同步到Lakehouse，确保数据的一致性。设置完主键需要通过[实时数据接口](java_reference/realtime-upload.md)来处理数据。在CDC实时写入过程中，系统将依据主键自动进行数据去重，以维护数据的准确性和完整性。只支持建表时指定。具体参考文档参考[主键介绍](primary-key.md)
-
-```
-CREATE    TABLE pk_table 
-(id int, col string PRIMARY KEY (id));
-
-CREATE    TABLE pk_table 
-(id int PRIMARY KEY, col string);
---分桶表定义主键
-CREATE    TABLE pk_table (
-          id int,
-          col string,
-          cluster_key string,
-          PRIMARY key (id)
-          ) CLUSTERED BY (id, cluster_key) SORTED BY (id) INTO 16 BUCKETS;
-
---分区表定义主键
-CREATE    TABLE pk_table (
-          id int,
-          col string,
-          pt string,
-          PRIMARY key (id, pt)
-          ) PARTITIONED BY (pt);
-```
-
-#### 自增列（IDENTITY\[(seed)]）
-
-* **IDENTITY\[(seed**)]:支持指定自增。无法保证序列中的值是连续的（无间隙），也无法保证序列值按特定顺序分配。因为表中可能会发生其他并发插入。这些限制是设计的一部分，目的是提高性能。具体使用参考[IDENTITY Column文档](IDENTITY-Column.md)
-
-```
-CREATE    TABLE identity_test (id bigint IDENTITY(1), col string);
-```
-
-#### 生成列（GENERATED ALWAYS AS）
-
-* **GENERATED ALWAYS AS (expr**)：通过表达式`expr`自动生成列的值。表达式可以包含常量和内置标量确定性SQL函数，不支持非确定性函数如（current\_date\random\current\_timestamp\上下文函数）或运算符，不支持聚合函数、窗口函数或表函数。支持分区列使用生成列
-
-```
-CREATE TABLE t_genet (col1 TIMESTAMP,pt STRING GENERATED ALWAYS AS (date_format(col1, 'yyyy-MM-dd'))) PARTITIONED BY (pt);
-```
-
-#### 默认值（DEFAULT）
-
-* **DEFAULT default\_expression**：为新添加的列定义一个默认值。如果在INSERT、UPDATE或MERGE操作中未指定该列的值，将自动使用此默认值。对于添加列之前已存在的数据行，该列将填充为null。支持非确定性函数如（current\_date\random\current\_timestamp\上下文函数）和常量值
-
-```
-CREATE TABLE t_default(id INT,col1 STRING DEFAULT current_timestamp());
-```
-
-### 索引定义（index\_definition\_list）
-
-#### 基本语法
-
-```
-INDEX index_name (col_name) index_type [COMMENT 'xxxxxx'] [PROPERTIES('key'='value')]
-```
-
-**columns\_difinition**:定义表的字段信息，最后一个字段必须使用逗号隔开
-
-**INDEX**：关键字
-
-**index\_name**：自定义index的名称
-
-**column\_name**：需要添加索引的字段名称
-
-**index\_type**：索引类型，目前支持[bloomfilter](BLOOMFILTER-INDEX.md)、[inverted](inverted-index.md)、[vector](vector-index.md)
-
-**COMMENT**：指定index的说明信息
-
-**PROPERTIES**：指定INDEX的参数,不同的索引支持不同的参数具体参考对应索引文档
-
-### 分区（PARTITIONED BY）
-
-分区是一种通过在写入时将相似的行分组在一起来加快查询速度的方法。使用分区可以达到数据裁剪，优化查询。查询表时通过WHERE子句查询指定所需查询的分区，避免全表扫描，提高处理效率，降低计算资源。具体可以参考[参考分区介绍](partition_table.md)。 注意执行写入分区时单个任务目前限制2048个分区，超出此限制将会报错：`The count of dynamic partitions exceeds the maximum number 2048`。插入之前建议您先统计分区的数量如：`select count(distinct pt) from table`。如果您确实有这么多分区可以分批次导入或者您可以通过添加参数set cz.sql.table.sink.max.partition.per.thread=10000来修改此限制，lakehouse的分区总数没有限制，会在单个任务限制。如果您的数据量较小建议可以不用设置cluster key和partiiton key。建议单分区和cluster key在百MB到GB级别。例如parquet格式文件压缩后128MB
-
-支持两种写法
-第一种分区字段和类型在create table时声明，在PARTITIONED BY字据中声明字段即可
-
-```SQL
-CREATE TABLE prod.db.sample (
-id bigint,
-category string,
-data string
-)
-PARTITIONED BY(category)
-```
-
-第二种分区字段和类型写在PARTITIONED BY语句中。
-
-```SQL
-CREATE TABLE prod.db.sample (
-id bigint,
-data string)
-PARTITIONED BY(category string)
-```
-
-### 分桶表（CLUSTERED BY）
-
-* CLUSTERED BY：指定Hash Key。Lakehouse将对指定列进行Hash运算，将数据根据Hash值分散到各个数据分桶中。为了避免数据倾斜和热点，并提高并行执行效果，建议选择取值范围大、重复键值少的列作为Hash Key。通常在进行join操作时会有明显效果。建议在数据量大的场景下使用CLUSTERED BY，一般按照一个桶的大小在128MB到1GB之间。如果没有指定分桶，默认为256个buckets。建议SORTED BY和CLUSTERED BY保持一致，以获得更好的性能。当指定SORTED BY子句后，行数据将按照指定的列进行排序。  更多信息可以参考[分桶](cluster-table.md)
-
-```
---指定分桶并指定排序
-CREATE TABLE sales_data (
-    sale_id INT,
-    product_id INT,
-    quantity_sold INT,
-    sale_date DATE
-) CLUSTERED BY (product_id)
-SORTED BY (sale_date DESC)
-INTO 50 BUCKETS;
---指定分桶并指定桶的个数
-CREATE TABLE sales_data (
-    sale_id INT,
-    product_id INT,
-    quantity_sold INT,
-    sale_date DATE
-) CLUSTERED BY (product_id)
-INTO 50 BUCKETS;
-```
-
-### SORTED BY
-
-SORTED BY：指定文件内字段的排序方式。Lakehouse的SORTED BY可以单独使用，单独使用时表示在文件内排序。指定SORTED BY可以加速数据检索速度，但是写入时由于要排序，写入时可能会增加耗时
-
-```
-CREATE TABLE sales_data (
-    sale_id INT,
-    product_id INT,
-    quantity_sold INT,
-    sale_date DATE
-) 
-SORTED BY (sale_date DESC);
-```
-
-### PROPERTIES
-
-* 支持设置生命周期'data\_lifecycle'='day\_num'[参考生命周期介绍](data-lifecycle.md)
-* 开启[TABLE STREAM](tablestream_summary.md) ，建表时指定'change\_tracking' = 'true'并不会生效，请使用alter开启
-  ALTER table test\_table set PROPERTIES ('change\_tracking' = 'true');
-* 设置表的缓存策略。partiton.cache.policy.latest.count=num设置表的缓存策略。计算集群可以通过配置 `preload_table`，定时或被触发拉取 `preload_table` 中指定的表数据到计算集群本地的 SSD 硬盘上进行缓存。您还可以在表上设置缓存策略。
-  例如，`partition.cache.policy.latest.count=10` 表示缓存最近的 10 个分区，当新分区添加时，旧分区的缓存将失效。也可以通过alter命令添加该参数
-  例如ALTER table test\_table set PROPERTIES ('partition.cache.policy.latest.count' =10);
-* 设置表的保留周期'data\_retention\_days'='num'，配置Time Travel的数据保留周期，以决定数据在时间旅行窗口中保留的时间长度。
-
-```
---设置数据生命周期和表删除数据的保留周期
-CREATE TABLE historical_prices (
-    ticker_symbol STRING,
-    trading_date DATE,
-    closing_price DECIMAL(10, 2)
-) PROPERTIES (
-    'data_lifecycle' = '365',
-    'data_retention_days' = '7'
-);
---修改已有表的生命周期
-ALTER TABLE historical_prices SET PROPERTIES(    'data_lifecycle' = '1')
-```
-
-### 使用LIKE语句建表
-
-```SQL
-CREATE TABLE [ IF NOT EXISTS ] table_name
-LIKE source_table
-[ COMMENT 'table_comment' ];
-```
-
-使用LIKE语句创建新表时，目标表将具有与源表相同的表结构，但不会复制数据。
-
-### 使用AS语句建表
-
-CREATE TABLE AS SELECT（简称CTAS）语句可用于同步或异步查询原表，并基于查询结果创建新表，然后将查询结果插入到新表中。需要注意的是，通过这种方式创建的表不会复制分区信息。
-
-```SQL
-CREATE TABLE [ IF NOT EXISTS ] table_name
-[ AS select_statement ];
-```
-

-) PROPERTIES (
-    'data_lifecycle' = '365',
-    'data_retention_days' = '1'
-) COMMENT '历史股价表';

-
-```sql
-CREATE TABLE IF NOT EXISTS customer_feedback (
-    feedback_id BIGINT COMMENT '反馈ID',
-    feedback JSON COMMENT '反馈内容'
-) COMMENT '客户反馈表';
-```
-
-# 使用说明
-
-### 分区和分桶
-
-* **分区策略的选择**：根据查询模式选择合适的分区字段。通常来说，应该选择那些能够有效缩小扫描范围的列作为分区键。比如时间戳列非常适合用作日期范围查询的分区键。
-
-* **分桶数量的设定**：分桶数目应当根据预计的数据量及硬件资源配置来调整。一般来说，每个bucket大小应在 256MB 到 1GB 之间。过多或过少的分桶都会影响到系统的整体性能。为了获得最佳效果，建议测试不同配置下的表现，并据此做出适当调整。
-
-* **排序字段的选择**：当使用 `SORTED BY` 子句时，选择那些频繁出现在过滤条件中的列作为排序依据。良好的排序可以帮助加速点查询和范围查询的速度，但同时也增加了写入成本。因此，在权衡利弊后作出决策非常重要。
-
-### 索引
-
-用户可以在建表的同时创建多个列的索引。索引也可以在建表之后再添加。如果在之后的使用过程中添加索引，如果表中已有数据，则需要重写所有数据，因此索引的创建时间取决于当前数据量。
-
-### 表属性设置的最佳实践
-
-* **启用数据生命周期管理**：通过设置 `data_lifecycle` 属性，可以让系统自动清理不再需要的历史数据。这对于节省存储非常有用，尤其是在处理日志或交易记录等具有明确保留期限的数据集时
-* **配置变更跟踪**：如果你的应用场景涉及需要获取表的数据变化，则需要开启 `change_tracking` 。常见场景如[TABLE STRAM](tablestream_summary.md)
-* **删除数据设置数据保留周期**:此参数定义了在被删除数据被保留的时间长度，对于需要进行历史数据查询的场景非常重要。例如，[table stream](tablestream_summary.md)、[restore](restore.md) 和[dynamic table](dynamic-table-introduce.md) 等功能都会依赖于这个保留周期设置。Lakehouse默认保留数据一天。根据您的业务需求，您可以通过调整 `data_retention_days` 参数来延长或缩短数据的保留周期。请注意，调整数据保留周期可能会影响存储成本。延长保留周期会增加存储需求，从而可能增加相关的费用。

-# Table Stream 功能
-
-Table Stream是一种实时数据流，用于记录对表所做的数据操作语言（DML）更改，包括插入、更新和删除操作。同时，Table Stream还提供有关每次更改的元数据，以便您可以根据更改的数据采取相应操作。支持在Table、Dynamic Table、Materialized View、External Table(Kafka)创建Table Stream，同时也支持在 External Volume 上创建 Volume Stream，用于监听外部对象存储（如 OSS）中的文件变更事件。
-
-## Table Stream 语法
-
-**Table、Dynamic Table、Materialized View 创建 Table Stream 语法**
-
-```SQL
-CREATE [OR REPLACE] TABLE STREAM [IF NOT EXISTS]
-  <name>
-  ON TABLE <table_name>
-  [TIMESTAMP AS OF timestamp_expression]
-  [COMMENT = '<string_literal>']
-  WITH PROPERTIES ('TABLE_STREAM_MODE' = 'APPEND_ONLY|STANDARD','SHOW_INITIAL_ROWS'='TRUE|FALSE');
-```
-
-* `<name>`：Table Stream的名称。
-
-* `<table_name>`：要获取增量的基表。不支持view。
-
-* `TIMESTAMP AS OF timestamp_expression`：（可选）指定Table Stream应从底层表开始接收更新的时间戳表达式。如果省略此参数，Table Stream将从当前时间开始接收更新。
-
-  * `timestamp_expression`返回结果是一个标准的时间戳类型的表达式，TIMESTAMP AS OF指定的最早时间戳取决[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。如果未指定则使用当前时间戳的版本数据，例如：
-    * `'2023-11-07 14:49:18'`，即可以强制转换为时间戳的字符串。
-    * `cast('2023-11-07 14:49:18 Asia/Shanghai' as timestamp)`。
-    * `current_timestamp() - interval '12' hours`。
-    * 本身就是时间戳或可强制转换为时间戳的任何其他表达式。
-
-* `COMMENT`：（可选）Table Stream的注释。
-
-* `'TABLE_STREAM_MODE' = 'APPEND_ONLY|STANDARD'`：（必选）值二选一，APPEND\_ONLY和STANDARD。
-
-  * APPEND\_ONLY只记录对象的INSERT操作的数据。Update和delete操作不会记录。例如，最初在表中插入了10行，然后在点位没有移动的时候执行delete操作删除5行，Table Stream仍然记录10行操作。
-  * STANDARD模式：STANDARD模式下可以跟踪源对象的所有DML变化，包括插入、更新和删除（包括表截断）。这种提供行级别的变化是通过将所有变化的delta数据进行连接加工来提供行级别增量。Table Stream中的delta变化指的是在两个事务时间点之间发生的数据变化。例如，如果在Table Stream的offset之后，有一个行被插入，然后被更新，那么delta变化就是一个新的行。如果在stream的offset之后，有一个行被插入，然后被删除，那么delta变化就是没有这个行。换句话说，delta变化会反映源对象的最新状态，而不是历史变化。
-
-* SHOW\_INITIAL\_ROWS:可选参数，指定为TRUE时，创建stream时候记录下table当时的版本，第一次消费该stream，永远拿的是创建时的那个版本，同时第一次消费时，所有数据都是insert模式，第一次消费结束后，后续的行为就和之前行为一样，从某个版本到下次版本之间的Delta数据。
-
-### 注意事项
-
-* 在创建Table Stream之前，必须在基表上执行以下操作：
-
-```SQL
-ALTER TABLE table_name set PROPERTIES ('change_tracking' = 'true');
-```
-
-* TIMESTAMP AS OF指定的最早时间戳取决[TIME TRAVEL](TIMETRAVEL.md)(data\_retention\_days)参数，如果指定的版本不存在则会报错。此参数定义了在被删除数据被保留的时间长度，Lakehouse默认保留数据一天。根据您的业务需求，您可以通过调整 `data_retention_days` 参数来延长或缩短数据的保留周期。请注意，调整数据保留周期可能会影响存储成本。延长保留周期会增加存储需求，从而可能增加相关的费用。
-* 通过实时上传数据写入的数据一分钟之后才可以读取，Table Stream 只能读取已经提交的数据。实时任务写入的数据需要等待 1 分钟才能确认，所以 Table Stream 也要等 1 分钟才能看到。
-
-### 使用案例
-
-案例1：创建APPEND\_ONLY模式的Table Stream
-
-```SQL
--- 清理环境
-DROP      TABLE IF EXISTS data_change_test;
-
-DROP      TABLE STREAM IF EXISTS data_change_test_stream;
-
--- 创建测试表
-CREATE    TABLE data_change_test (id int, name string);
-
-INSERT    INTO data_change_test
-VALUES    (1, 'apple');
-
--- 在data_change_test上创建TABLE stream，获取从当前时间开始插入的增量记录
-ALTER     TABLE data_change_test set PROPERTIES ('change_tracking' = 'true');
-
-CREATE    TABLE STREAM data_change_test_stream ON TABLE data_change_test
-WITH      PROPERTIES ('TABLE_STREAM_MODE' = 'APPEND_ONLY');
-
--- 插入测试数据
-INSERT    INTO data_change_test
-VALUES    (2, 'banana');

-## Kafka Table Stream
-
-支持在Kafka外部表上创建表流（Table Stream），实现实时消费Topic数据.
-
-#### 语法
-
-```sql
-CREATE TABLE STREAM [IF NOT EXISTS] stream_name 
-ON TABLE external_kafka_table 
-[TIMESTAMP AS OF timestamp_expression]  -- 可选，指定消费起始时间点位
-WITH PROPERTIES (
-  'table_stream_mode' = 'append_only',  -- 仅支持追加模式
-  'show_initial_rows' = 'true'|'false'
-);
-```
-
-### 参数说明
-
-* `TIMESTAMP AS OF`   :指定消费起始时间点（可选），支持格式：
-  * **明确时间戳**：`'2023-01-01 12:00:00'`
-  * **时间函数**：`CURRENT_TIMESTAMP() - INTERVAL '1' HOUR`
-* `show_initial_rows`  :控制初始数据加载行为：
-  * `true`：加载从外部表创建时指定的点位到Table Stream指定的点位之间的历史数据
-  * `false`：从最新点位（`latest`）开始消费，不加载历史数据（默认值）
-* `table_stream_mode`  : 固定为`append_only`，仅处理Kafka新增数据（不支持更新/删除操作）
-
-#### 示例
-
-1. Kafka 外部表创建
-   首先，您需要创建一个 [Kafka 外部表](kafka-external-table.md)。这是创建 Table Stream 的基础。以下是创建 Kafka 外部表的语法：
-
-创建Kafka Connection
-
-```SQL
-CREATE STORAGE CONNECTION pipe_kafka
-    TYPE kafka
-    BOOTSTRAP_SERVERS = ['47.99.48.62:9092']
-    SECURITY_PROTOCOL = 'PLAINTEXT';
-```
-
-创建Kafka外部表
-
-```SQL
-CREATE EXTERNAL TABLE external_table_kafka (   
- key_column binary,   
- value_column binary NOT NULL)
-USING kafka
-OPTIONS (    'group_id' = 'external_table_lh',    'topics' = 'test_long')
-CONNECTION pipe_kafka;
-```
-
-* `external_table_kafka` 是外部表的名称。
-* `key_column` 和 `value_column` 分别代表 Kafka 消息的键和值，其中 `value_column` 是必需的。
-* `USING kafka` 指定了使用 Kafka 作为数据源。
-* `OPTIONS` 部分包含了 Kafka 消费者配置，如消费者组 ID (`group_id`) 和要订阅的主题 (`topics`)。
-* `CONNECTION pipe_kafka` 指定了与 Kafka 的连接配置，这通常包括 Kafka 集群的地址和其他连接参数。
-
-2. 创建 Table Stream
-
-在 Kafka 外部表的基础上，您可以创建一个 Table Stream，用于实时处理 Kafka 数据流。以下是创建 Table Stream 的语法：
-
-```
-CREATE TABLE STREAM kafka_table_stream_pipe1
- ON TABLE external_table_kafka
-WITH PROPERTIES (
-    'table_stream_mode' = 'append_only',
-    'show_initial_rows' = 'true');
-```
-
-^
-
-## Volume Stream
-
-**CREATE VOLUME STREAM 语法**
-
-用于在 External Volume 的 Directory Table 上创建 Volume Stream，以监听外部对象存储中文件的新增与删除事件。
-
-```
-CREATE [OR REPLACE] STREAM [IF NOT EXISTS] <name>
-  ON VOLUME <volume_name>;
-```
-
-**参数说明**
-
-`<name>`：Volume Stream 的名称。
-
-`<volume_name>`：要监听的 External Volume 名称。该 Volume 必须满足以下条件：
-
-* 已开启目录功能，即建表时指定 DIRECTORY = (ENABLE = TRUE)；
-* 已开启递归监听，即建表时指定 RECURSIVE = TRUE。
-
-**示例**
-
-```
--- 创建Volume Stream，追踪文件新增和删除
-CREATE OR REPLACE STREAM str_app_log
-  ON VOLUME vol_app_log;
-
-```
-
-**注意事项**
-
-* 创建 Volume Stream 之前，须开启 DIRECTORY = (ENABLE = TRUE) 和 RECURSIVE = TRUE 。
-* Volume Stream 本质上是构建在 Directory Table 之上的 Table Stream，消费机制与 Table Stream 完全一致：仅 DML 语句（如 INSERT INTO ... SELECT FROM stream）会推进消费点位，纯 SELECT 查询不会推进。
-* 由于对象存储事件通过消息队列传递存在约 1 分钟的延迟，文件上传后需等待约 1 分钟才能在 Volume Stream 中查询到对应的变更记录。

-# 创建计算集群
-
-## 功能描述
-
-本功能允许用户根据指定的名称和配置，在执行SQL的工作空间下创建计算集群。计算集群（Virtual-Cluster，简称：VCluster）是云器Lakehouse提供的计算资源集群服务，提供执行查询分析所需的CPU、内存、临时存储等资源。用户可以使用计算集群执行各类ETL、流式分析、即席查询及数据集成等作业。在Lakehouse中执行需要计算的SQL Select查询或各类DML操作（如DELETE,INSERT,UPDATE等）时，都将使用计算集群。
-
-计算集群包括通用型（GENERAL PURPOSE VIRTUAL CLUSTER，简称：GP类型）、分析型（ANALYTICS PURPOSE VIRTUAL CLUSTER，简称：AP类型）和同步型（INTEGRATION VIRTUAL CLUSTER）三种类型。
-
-通用型计算集群中，提交至计算集群的作业共享集群内的计算资源，适合处理离线作业；分析型集群具备多计算实例、自动弹缩的功能特性，适合处理在线、高并发类的作业。同步型集群专门用于数据集成任务。

-# 创建阿里云私网连接终端节点
-
-当您需要在云厂商 VPC 内通过内网访问云器 Lakehouse 服务时，您需要在阿里云创建连接云器 Lakehouse 终端节点服务的终端节点。然后，将访问云器 Lakehouse 的 JDBC 连接或 API 的域名替换为终端节点的域名。
-
-:-: ![](.topwrite/assets/privatelink客户访问LH-例子.png)
-
-## 操作步骤
-
-1\. **添加白名单**。首先请将您的云平台账号（角色）添加至云器 Lakehouse 私有网络连接的白名单中。如下图所示：
-
-:-: ![](.topwrite/assets/image_1733063925523.png =708)
-
-为保障 Lakehouse 能够正常读取您的终端节点状态，并增强获取您云服务平台内终端节点信息的安全性，请在云服务平台内创建独立的访问控制角色，并授权及添加 External ID。
-
-**ARN 和 External ID 值获取**：
-
-在阿里云“RAM 访问控制” > “角色”页面，选择希望添加其 ARN 的访问控制角色，分别复制其 ARN 和 External ID 的值。然后，回到云器 Lakehouse 页面，在添加白名单弹窗中，分别将上述两项内容复制到对应的选项中。&#x20;
-
-该角色的权限配置和 External ID 配置详见[获取阿里云ARN和ExternalID](alicloud-arn-externalid.md)。

-# 通过云器Lakehouse的多表实时同步和动态表实现变化数据捕获（CDC）及数据处理
-
-## 概要介绍
-
-在本快速入门中，我们将研究如何使用存储在 PostgreSQL 数据库中的客户交易数据，通过云器Lakehouse的多表实时同步将数据导入云器Lakehouse的表中，通过动态表进行实时数据处理，并进一步通过云器Lakehouse自带的DataGPT进行可视化数据探索和对话式数据分析，从而实现从数据摄取、数据处理和数据分析的实时全链路，以此来了解客户交易进行洞察分析。
-
-从ELT的角度来看，云器Lakehouse的多表实时同步实现了基于CDC的数据抽取（Data Extraction）和加载（Load），并且在该过程中实现了模式演进（Schema Evolution），也就是同步内容会包括源数据库的结构或模式（Schema）的变化。动态表Dynamic Table则以全新的方式实现了数据转换（Data Transform）。

-
-## Postgres环境
-
-### 概述
-
-在本节中，我们将建立一个 PostgreSQL 数据库并创建表来模拟金融公司的客户交易数据。
-
-### 启动数据库实例
-
-在开始此步骤之前，请确保已为[Mac](https://docs.docker.com/desktop/install/mac-install/)、[Windows](https://docs.docker.com/desktop/install/windows-install/)或[Linux](https://docs.docker.com/desktop/install/linux/)安装了 Docker Desktop 。确保您的机器上已安装[Docker Compose 。](https://docs.docker.com/compose/install/)
-
-1. 要使用 Docker 启动 PostgreSQL 数据库，您需要创建一个名为docker-compose.yaml的文件。此文件将包含 PostgreSQL 数据库的配置。如果您有另一个容器客户端，请启动容器并使用下面的 PostgreSQL 映像。
-2. 打开您选择的 IDE（比如VS Code），通过复制并粘贴以下内容来复制并粘贴此文件：
-
-```YAML
-services:
-  postgres:
-    image: "postgres:17"
-    container_name: "postgres17"
-    environment:
-      POSTGRES_DB: 'postgres'
-      POSTGRES_USER: 'postgres'
-      POSTGRES_PASSWORD: 'postgres'
-    ports:
-      - "5432:5432"
-    command:
-      - "postgres"
-      - "-c"
-      - "wal_level=logical"
-    volumes:
-      - ./postgres-data:/var/lib/postgresql/data
-```
-
-3. 打开终端并导航到docker-compose.yaml文件所在的目录。运行以下命令启动 PostgreSQL 数据库：
-
-```Shell
-docker-compose up -d
-```
-
-### 连接数据库
-
-要使用 Visual Studio Code 或 DBV/DBGrid/PyCharm 或您选择用于数据库连接的任何 IDE 连接到预配置的数据库，请使用提供的凭据执行以下步骤：
-
-1. 打开您选择的工具以连接 PostgreSQL 数据库
-
-   1. 对于 VSCode，你可以使用[PostgreSQL 扩展](https://marketplace.visualstudio.com/items?itemName=cweijan.vscode-postgresql-client2)
-   2. 对于 PyCharm，您可以使用[数据库工具和 SQL 插件](https://www.jetbrains.com/help/pycharm/database-tool-window.html)
-
-2. 单击`+`符号或类似符号以添加数据源
-
-3. 使用这些连接参数：
-
-   1. 用户：`postgres`
-   2. 密码：`postgres`
-   3. 网址：`jdbc:postgresql://localhost:5432/`
-
-4. 测试连接并保存
-
-5. 为了能让云器Lakehouse Studio通过公网访问到Postgres数据库，务必给Postgres数据库做公网NAT映射。
-
-### 加载数据
-
-1. 在 PostgreSQL 中运行以下[postgres脚本](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/scripts/postgresql_setup.sql)来创建数据库、模式和表：
-
-```SQL
-CREATE SCHEMA raw_cdc;
-SET search_path TO raw_cdc;
-
-DROP TABLE IF EXISTS postgres.raw_cdc.customers;
-DROP TABLE IF EXISTS postgres.raw_cdc.merchants;
-DROP TABLE IF EXISTS postgres.raw_cdc.products;
-DROP TABLE IF EXISTS postgres.raw_cdc.transactions;
-
-CREATE TABLE postgres.raw_cdc.customers (
-   customer_id INTEGER PRIMARY KEY,
-   firstname VARCHAR,
-   lastname VARCHAR,
-   age INTEGER,
-   email VARCHAR,
-   phone_number VARCHAR
-);
-
-CREATE TABLE postgres.raw_cdc.merchants (
-   merchant_id integer PRIMARY KEY,
-   merchant_name VARCHAR,
-   merchant_category VARCHAR
-);
-
-CREATE TABLE postgres.raw_cdc.products (
-   product_id INTEGER PRIMARY KEY,
-   product_name VARCHAR,
-   product_category VARCHAR,
-   price DOUBLE PRECISION
-);
-
-CREATE TABLE postgres.raw_cdc.transactions (
-   transaction_id VARCHAR PRIMARY KEY,
-   customer_id INTEGER,
-   product_id INTEGER,
-   merchant_id INTEGER,
-   transaction_date DATE,
-   transaction_time VARCHAR,
-   quantity INTEGER,
-   total_price DOUBLE PRECISION,
-   transaction_card VARCHAR,
-   transaction_category VARCHAR
-);
-```
-
-2. 下载这些 csv 文件并将其保存到本地计算机的目录中：
-
-   1. [客户.csv](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/postgres_csv/customers.csv)
-   2. [商家.csv](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/postgres_csv/merchants.csv)
-   3. [产品.csv](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/postgres_csv/products.csv)
-   4. [交易.csv](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/postgres_csv/transactions.csv)
-
-3. Postgres数据加载方式1，通过PG的Copy命令加载
-
-   1. 在将数据加载到 PostgreSQL 数据库之前，我们需要将文件从本地计算机移动到 Docker 容器。
-   2. 导航到您的终端，使用以下命令获取 Docker 容器 ID：
-   3. ```Shell
-      docker ps
-      ```
-   4. 要将 CSV 文件复制到容器，请在终端中运行以下命令，将文件路径替换为实际文件路径，并将其替换`container_id`为上一个命令中的实际容器 ID：
-   5. ```Shell
-      docker cp /Users/your_username/Downloads/customers.csv container_id:/tmp/customers.csv
-      docker cp /Users/your_username/Downloads/merchants.csv container_id:/tmp/merchants.csv
-      docker cp /Users/your_username/Downloads/products.csv container_id:/tmp/products.csv
-      docker cp /Users/your_username/Downloads/transactions.csv container_id:/tmp/transactions.csv
-      ```
-   6. 返回 PostgreSQL 控制台，运行以下 SQL 命令将文件从容器加载到 PostgreSQL 表：
-
-```SQL
-COPY postgres.raw_cdc.customers FROM '/tmp/customers.csv' DELIMITER ',' CSV HEADER;
-COPY postgres.raw_cdc.merchants FROM '/tmp/merchants.csv' DELIMITER ',' CSV HEADER;
-COPY postgres.raw_cdc.products FROM '/tmp/products.csv' DELIMITER ',' CSV HEADER;
-COPY postgres.raw_cdc.transactions FROM '/tmp/transactions.csv' DELIMITER ',' CSV HEADER;
-```
-
-4. Postgres数据加载方式2，通过Python脚本加载
-
-将以下代码Copy进Python文件或者Notebook然后运行，也可以直接下载[这个Python文件](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/scripts/load-data-into-pg-by-python.py)。
-
-```Python
-import psycopg2
-
-# 数据库连接信息
-conn = psycopg2.connect(
-    dbname="postgres",
-    user="postgres",
-    password="postgres",
-    host="localhost",
-    port="5432"
-)
-cur = conn.cursor()
-# 设置 search_path 
-cur.execute("SET search_path TO raw_cdc;")
-import os
-# 设置 CSV 文件目录
-csv_directory = "csv/"
-
-def load_csv_to_postgres(csv_file, table_name):
-    with open(csv_file, 'r') as f:
-        cur.copy_expert(f"COPY {table_name} FROM STDIN WITH CSV HEADER DELIMITER ','", f)
-    conn.commit()
-
-# 遍历目录中的所有 CSV 文件并加载到对应的表中
-for filename in os.listdir(csv_directory):
-    if filename.endswith(".csv"):
-        csv_file = os.path.join(csv_directory, filename)
-        table_name = os.path.splitext(filename)[0]  # 文件名去掉扩展名作为表名
-        print(f"Loading {csv_file} into table {table_name}...")
-        load_csv_to_postgres(csv_file, table_name)
-        print(f"Loaded {csv_file} into table {table_name} successfully!")
-# 关闭游标和连接
-cur.close()
-conn.close()
-```
-
-5. 接下来，确保运行`CREATE PUBLICATION`命令以启用模式中表的逻辑复制`raw_cdc`。这将允许下文的实时同步任务捕获对 PostgreSQL 数据库中表所做的更改：
-
-```SQL
-CREATE PUBLICATION agent_postgres_publication FOR ALL TABLES;
-```
-
-发布（Publication）是 PostgreSQL 逻辑复制的一部分，它允许用户定义一组表的变更（插入、更新、删除），这些变更将被传送给一个或多个订阅者（Subscribers）。逻辑复制是 CDC 的一种实现方式，它捕获并传播数据库表中的数据变更。换句话说，执行这条语句之后，PostgreSQL 会捕获数据库中所有表的数据变更，并且这些变更可以被订阅者接收和处理。从而实现 CDC 的数据变化记录。
-
-6. 最后，通过运行以下 SQL 命令检查表是否已正确加载：
-
-```SQL
-SELECT * FROM postgres.raw_cdc.customers;
-SELECT * FROM postgres.raw_cdc.merchants;
-SELECT * FROM postgres.raw_cdc.products;
-SELECT * FROM postgres.raw_cdc.transactions;
-```
-
-## 创建并启动云器Lakehouse CDC多表实时同步任务
-
-### 概述
-
-您将使用[云器Lakehouse Studio](https://accounts.clickzetta.com/)来基于界面操作、以无代码的方式来创建多表实时同步任务，将数据从Postgres的表加载到云器Lakehouse的表中。
-
-### 创建Postgres数据源
-
-导航到管理->数据源，单击“新建数据源”并选择Postgres以创建Postgres数据源，使得Postgres能被云器Lakehouse可访问。
-
-:-: ![](.topwrite/assets/image_1735115653296.png =600)
-
-^
-
-:-: ![](.topwrite/assets/image_1735115660694.png =600)
-
-* 数据源名称：PG\_CDC\_DEMO
-* 连接参数：同上节Postgres环境连接参数。
-* 请注意务必配置正确的数据库所在的时区，避免数据同步失败。
-
-### 创建多表实时同步任务
-
-导航到开发->任务，单击`+`以创建新工作目录和工作表任务，然后选择“多表实时同步”。
-
-* 选择“多表实时同步”：
-
-:-: ![](.topwrite/assets/image_1735115675871.png =600)
-
-创建多表实时同步任务并存放在刚才构建环境的同一个目录里：
-
-* 任务名称：02\_Ingestion\_CDC
-* 来源数据：选择Postgres
-
-:-: ![](.topwrite/assets/image_1735115689339.png =600)
-
-  来源数据选择上一步创建的Postgres数据源：PG\_CDC\_DEMO,选择之后会自动显示该数据源可访问的数据库、Schema和表，并选中所有表（所有表都需要同步）：
-
-:-: ![](.topwrite/assets/image_1735115698983.png =624)
-
-  选择或者新建CDC同步的SlotName，请注意同一个Slot不要被两个任务共享消费，以免数据丢失：
-
-:-: ![](.topwrite/assets/image_1735115710124.png =600)
-
-  目标表配置：
-
-  选择目标数据源下已有的Schema作为目标表存储位置。
-
-:-: ![](.topwrite/assets/image_1735115718468.png =663)
-
-  配置并检查表、字段映射关系：
-
-  云器Lakehouse会自动形成表和字段的映射，包括数据类型的映射。如果选中的云器Lakehouse命名空间里没有对应的表，多表实时同步任务在任务启动时会自动检查并新建表，无需手动提前创建。
-CDC同步要求在源端表都有主键，多表实时同步会在Lakehouse目标表里自动创建对应的[主键](primary-key.md)。
-
-:-: ![](.topwrite/assets/image_1735115731100.png =641)
-
-  
-
-配置同步规则：
-
-  Schema Evolution，即“模式演进”，是指在数据库管理系统中，随着时间的推移和需求的变化，数据库的结构或模式（Schema）进行修改和适应的过程。模式演变通常涉及对数据库表结构、字段、数据类型、关系和约束的更改，而这些更改不会中断现有系统的运行或导致数据丢失。
-
-  实时同步任务的同步规则中，可以配置对于源端表和字段的变更的自动处理策略：
-
-* 设置来源表删除字段后的行为。
-* 设置来源表新增字段的行为。重命名字段视为字段删除、命名后字段被识别为字段新增。
-* 设置来源表新增字段后的行为。
-* 设置数据源同步对象被删除的行为。重命名表视为删除，重命名后的表视为新建表。
-
-  此外，同步规则中也支持设定需要处理的源端变更消息的类型，请按需设定。比如某些场景下，期望目标端的数据一直累加，不处理源端“删除”变更，在改配置中去除掉“删除”选项即可。
-
-:-: ![](.topwrite/assets/image_1735115747197.png =652)
-
-### 提交多表实时同步任务并启动
-
-* **提交**多表实时同步任务：
-
-:-: ![](.topwrite/assets/image_1735115761930.png =600)
-
-* **运维**多表实时任务：
-
-:-: ![](.topwrite/assets/image_1735115774424.png =600)
-
-* **启动**多表实时任务：
-
-:-: ![](.topwrite/assets/image_1735115784817.png =600)
-
-* 并选择“全量数据同步”：
-
-是否在增量同步前，先进行全量的数据同步。请注意，此配置只在任务上线后第一次启动可以选择。
-
-:-: ![](.topwrite/assets/image_1735115795219.png =474)
-
-### 查看全量同步状态
-
-在上文的“Postgres环境”步骤，已经通过Copy或者Python脚本方式，往Postgres的四张表中加载了数据。上一步选择的“全量数据同步”，在增量数据同步开始前，实现全量数据的同步。
-
-:-: ![](.topwrite/assets/image_1735115806467.png =613)
-
-全部4张表的全量同步状态和增量同步状态都正常，没有发生Failover。
-
-:-: ![](.topwrite/assets/image_1735115814661.png =789)
-
-可以看到全量同步已经完成，此后，增量同步状态会自动转换成“正在同步”，不需要人工干预操作。
-
-## 多表实时同步的增量同步过程
-
-### 在数据源插入新增数据
-
-在Postgres的源表中插入数据，通过已启动的实时多表同步任务实现增量数据同步，并查看实时多表同步任务的同步状态。
-
-多表实时同步在增量同步过程中，使用了Lakehouse的[Java实时编程接口](java_reference/realtime-upload.md)将数据实时写入Lakehouse的主键表中。
-
-将以下代码Copy进Notebook并运行，或者[直接下载](https://github.com/yunqiqiliang/czguide-intro-to-cdc-using-clickzetta-rtsync-dynamic-tables/blob/main/scripts/pg-insert-transaction.ipynb)：
-
-* 创建数据库连接
-
-```Python
-import psycopg2
-import random

-## 通过动态表处理多表实时同步进来的数据
-
-概述
-
-您将使用[云器Lakehouse Studio](https://accounts.clickzetta.com/)来创建动态表（Dynamic Table），将从Postgres的表通过多表实时同步到云器Lakehouse的数据进行实时处理。
-
-### 创建动态表
-
-导航到开发->任务，单击“+选择“动态表”。
-
-:-: ![](.topwrite/assets/image_1735115842636.png =600)
-
-* 任务名称：03\_customer\_purchase\_summary
-* Schema选择：real\_time\_financial\_insights\_using\_change\_data\_capture\_cdc
-* 表名请输入：customer\_purchase\_summary
-* 在SQL代码里输入：
-
-```Python
-SELECT
-    t.transaction_id
-    , t.customer_id
-    , c.age AS customer_age
-    , t.product_id
-    , p.product_name
-    , p.product_category
-    , t.merchant_id
-    , m.merchant_name
-    , m.merchant_category
-    , t.transaction_date
-    , t.transaction_time
-    , t.quantity
-    , t.quantity * p.price AS total_price
-    , t.transaction_card
-    , t.transaction_category
-FROM
-    transactions t
-JOIN
-    customers c ON t.customer_id = c.customer_id
-JOIN
-    products p ON t.product_id = p.product_id
-JOIN
-    merchants m ON t.merchant_id = m.merchant_id
-AND
-    m.merchant_category = p.product_category;
-```
-
-  这段 SQL 查询的具体作用是通过多个表的连接，从 `transactions` 表中获取详细的交易记录，并从 `customers`、`products` 和 `merchants` 表中获取相关的信息。以下是详细的解释：
-
-  
-
-* **从** \*\*\*\*\`\`\*\* 表中提取交易记录\*\*：
-
-  * `t.transaction_id`：获取每笔交易的唯一标识符。
-  * `t.customer_id`：获取与交易相关联的客户的标识符。
-  * `t.product_id`：获取交易中涉及的产品的标识符。
-  * `t.merchant_id`：获取提供产品或服务的商家的标识符。
-  * `t.transaction_date` 和 `t.transaction_time`：获取交易发生的日期和时间。
-  * `t.quantity`：获取交易中购买的产品数量。
-  * `t.transaction_card`：获取用于交易的卡类型（如信用卡或借记卡）。
-  * `t.transaction_category`：获取交易的类别（例如购买或退款）。
-
-  
-
-* **从** \*\*\*\*\`\`\*\* 表中提取客户信息\*\*：
-
-  * 使用 `JOIN customers c ON t.customer_id = c.customer_id` 将 `transactions` 表与 `customers` 表连接，获取与交易相关联的客户信息。
-  * `c.age AS customer_age`：获取客户的年龄，并将其命名为 `customer_age`。
-
-  
-
-* **从** \*\*\*\*\`\`\*\* 表中提取产品信息\*\*：
-
-  * 使用 `JOIN products p ON t.product_id = p.product_id` 将 `transactions` 表与 `products` 表连接，获取交易中涉及的产品信息。
-  * `p.product_name`：获取产品的名称。
-  * `p.product_category`：获取产品的类别。
-  * `t.quantity * p.price AS total_price`：计算每笔交易的总价格（数量乘以产品单价），并将其命名为 `total_price`。
-
-  
-
-* **从** \*\*\*\*\`\`\*\* 表中提取商家信息\*\*：
-
-  * 使用 `JOIN merchants m ON t.merchant_id = m.merchant_id AND m.merchant_category = p.product_category` 将 `transactions` 表与 `merchants` 表连接，并确保商家的类别与产品类别匹配。
-  * `m.merchant_name`：获取商家的名称。
-  * `m.merchant_category`：获取商家的类别。
-
-通过这些连接和数据提取，这段查询语句生成了一个详细的结果集，每条记录包含交易的详细信息、客户信息、产品信息和商家信息，并计算了每笔交易的总价格，从而获得更全面和深入的交易分析。
-
-动态表则会直接根据生命式语法，按照要求定时刷新数据，从而达到数据动态变化的目的。

-
-:-: ![](.topwrite/assets/image_1735116077565.png =641)
-
-###  数据探查
-
-导航到分析域（选择“CDC交易数据分析”）->探索，就可以基于刚才自动创建的指标进行数据探索了。
-
-:-: ![](.topwrite/assets/image_1735116085712.png =638)
-
-###  对话式数据分析
-
-输入问题“Mastercard的交易次数，按照商家类别分布”，得到如下分析结果：
-
-:-: ![](.topwrite/assets/image_1735116092619.png =630)
-
-^
-
-其中，理解到Mastercard是要匹配交易卡 (transaction\_card = Mastercard)，这受益于DataGPT对transaction\_card 字段的值自动做了索引。
-
-交易次数是一个自动创建的指标，实现了指标口径的对齐。
-
-商家类别对应了字段merchant\_category，这受益于字段描述的自动生成，快速实现了语义对齐。
-
-输入问题：每个渠道购买‘消毒湿巾’产品的交易总数是多少？得到如下分析结果：
-
-:-: ![](.topwrite/assets/image_1735279174589.png =631)
-
-在Lakehouse表中，产品‘消毒湿巾’存储的是英文‘Disinfectant Wipes’。当用户问到‘消毒湿巾’，DataGPT会自动进行翻译从而做到精准适配，而不用用户一定要输入‘Disinfectant Wipes’，这充分发挥了大模型的优势，让数据分析更加简单。

-# 概述
-
-数据同步是云器 Lakehouse 内置的高效数据集成服务，支持在多种数据源之间同步数据，并利用调度系统创建自动化的同步任务。通过数据同步功能，用户无需编写代码，只需通过简单的向导式操作即可实现快速导入 Lakehouse、导出加工后数据或进行不同数据源之间的数据同步。
-
-^
-
-## 基本概念
-
-### 数据同步任务
-
-数据同步任务是用于从数据源采集数据并写入目标数据源的一种任务类型。根据数据同步的时效性，数据同步任务可分为离线同步任务和实时同步任务。在 Lakehouse Studio 中，数据同步任务通过界面配置实现任务定义和调度配置，无需编写代码。
-
-Lakehouse Studio 目前支持离线周期同步和实时同步两大类同步任务类型。在“开发 > 任务”中点击新建按钮，按需选择合适的任务类型。
-
-![](.topwrite/assets/image_1736153630510.png =600)
-
-^
-
-一个数据同步任务包含以下核心组件：
-
-1.  **数据来源**：同步任务的数据来源，包括数据库、文件系统、SaaS/应用、Lakehouse 空间数据源等。数据来源由数据源进行定义和管理。
-2.  **数据对象**：同步任务需要处理的数据来源下的数据对象，如数据库表、消息队列 Topic、文件系统文件等。
-3.  **对象及 Schema 映射**：定义来源数据对象与目标数据对象及其 Schema 之间的映射关系。
-4.  **数据目标**：数据写入的目标数据源，包括 Lakehouse 及其他外部数据源。
-5.  **任务设置**：影响任务运行的规则设置，如容错规则、并发设置、流量控制等。
-6.  **调度配置**：任务调度运行的规则及策略。
-
-### 数据源
-
-数据源是定义外部服务连接信息的对象，包括服务地址、认证信息、连接方式等。定义好的数据源可以在数据同步任务中作为数据来源或数据目标使用。数据源位于“管理 > 数据源”功能菜单下。
-
-![](.topwrite/assets/image_1736153771696.png =800)
-
-^
-
-## 使用示例
-
-### 示例：从MySQL数据库同步数据到Lakehouse
-
-假设您有一个 MySQL 数据库，其中包含客户订单数据。您希望将这些数据同步到 Lakehouse，以便进行数据分析和处理。
-
-1.  在 Lakehouse 中创建一个新的数据同步任务。
-2.  选择 MySQL 数据库作为数据来源，并指定相应的数据源连接信息。
-3.  选择需要同步的数据库表作为数据对象。
-4.  定义表结构及字段映射规则。
-5.  选择 Lakehouse 作为数据目标，并指定目标表。
-6.  根据需要配置任务设置和调度配置。
-7.  启动同步任务，数据将按照设定的规则从 MySQL 数据库同步到 Lakehouse。
-
-通过以上示例，您可以看到 Lakehouse 数据同步功能可以帮助您轻松实现不同数据源之间的数据同步，无需编写复杂的代码。这将大大提高数据处理效率，让您专注于数据分析和业务决策。

-# 数据生命周期
-
-数据生命周期（TTL）是指云器 Lakehouse 中表和表分区从最后一次更新时间算起的时间长度。在指定的时间周期内，如果数据没有发生变动，系统将自动回收这些数据。生命周期的单位是天，且取值为整数类型。
-
-## 数据生命周期的工作原理
-
-数据生命周期到期的回收依赖于数据的最后修改时间（last\_modified\_time）。对于非分区表，您可以通过 `desc extended` 命令查看 last_modified_time；对于分区表，您可以通过 `SHOW PARTITIONS EXTENDED table_name` 查看对应具体分区的 last_modified_time。当发生 DDL（数据定义语言）或 DML（数据操纵语言）操作时，last_modified_time 会更新。
-
-需要注意的是，到期的数据并不会立即被回收。您仍然可以查询这些数据，直到后台进程执行删除操作。通常，后台进程会在 24 小时内删除这些数据。此外，被回收的表仍然遵守 [数据保留周期](TIMETRAVEL.md)，您仍可以使用 [时间旅行](TIMETRAVEL.md) 功能进行查询。若需要恢复已删除的对象，可以使用 [undrop table](UNDROP-TABLE.md) 命令。
-
-## 设置数据生命周期
-
-生命周期单位为天，取值为正整数。设置为 '-1' 代表不开启生命周期，即数据将被永久保留。您可以在创建表时指定生命周期，也可以在表创建后进行修改。
-
-### 具体SQL操作方式
-
-**创建表时设置生命周期**
-
-```SQL
--- 创建表并设置生命周期为7天
-CREATE TABLE tname (col1 datatype1, col2 datatype2) PROPERTIES('data_lifecycle'='7');
--- 创建表并设置生命周期为7天，同时在生命周期到期时删除表结构
-CREATE TABLE tname (col1 datatype1, col2 datatype2) PROPERTIES('data_lifecycle'='7', 'data_lifecycle_delete_meta'='true');
-```
-
-**修改现有表的生命周期**
-
-```SQL
--- 修改表的生命周期为10天
-ALTER TABLE tname SET PROPERTIES ('data_lifecycle'='10');
--- 修改表的生命周期为10天，并在生命周期到期时删除表结构
-ALTER TABLE tname SET PROPERTIES ('data_lifecycle'='10', 'data_lifecycle_delete_meta'='true');
-```
-
-## 注意事项
-
-1.  生命周期回收任务每天不定时启动，每 12 小时轮询一次，会扫描全量分区。只有当 last_modified_time 超过生命周期指定的时间时，数据才会被回收。
-2.  生命周期回收主要针对表或分区，每天根据服务的繁忙程度进行，不能确保到期后立即被回收。
-3.  生命周期到期时，默认行为是不删除表结构，只清空数据。如果您希望删除表结构，请在设置生命周期时添加参数 `ALTER TABLE tname SET PROPERTIES ('data_lifecycle_delete_meta'='true')`。
-4.  修改生命周期时，例如当您将生命周期策略从 15 天更改为 30 天时，新策略会立即生效。但是由于生命周期回收任务每天不定时启动，通常每 12 小时轮询一次。在极少数情况下，如果在策略变更时，回收任务恰好启动并读到了旧的策略，可能会按照旧策略（15 天）回收部分数据。该现象属于系统设计的正常机制，不会影响未到期数据的安全。

-# 导入说明
-
-Lakehouse 从原理上提供了两种主要的数据写入方法，以适应不同的数据处理需求和性能考量。
-
-### **SQL 引擎直接拉取**
-
-Lakehouse 的 SQL 引擎能够直接从对象存储中拉取数据，这一方法特别适合于数据源已经位于对象存储的场景。未来，Lakehouse 计划扩展支持更多类型的数据源，以进一步提升数据接入的灵活性。
-
-* **优势**：SQL 引擎直接拉取数据，利用其性能优势，可以高效地处理存储在对象存储中的数据。使用 COPY 命令、Volume 可在导入过程中进行数据转换。
-* **计算资源**：执行 SQL 查询时会消耗计算资源（Virtual Cluster），但这种消耗是值得的，因为它提供了强大的数据处理能力。
-* **文件格式**：目前支持的文件格式包括 CSV、PARQUET 和 ORC，这些格式都是数据分析和处理中常用的格式。
-* **导入方式**：支持多种数据导入方式，如 COPY 命令、Volume、数据集成离线导入以及 SDK 批量上传（BulkloadStream）。
-
-### 向Ingestion Service推送数据
-
-Lakehouse 的 Ingestion Service 为需要实时数据写入的场景提供了解决方案。客户端将数据推送到服务端，由 Ingestion Service 接收并提交到表中，包括 SDK 实时数据流（RealtimeStream）和 CDC 实时写入。
-
-* **优势**：提高了数据写入的时效性，实现了实时写入和实时可读。
-* **资源消耗**：目前 Ingestion Service 处于预览版，使用该服务暂不计费。但请注意，未来将开始计费。
-* **适用场景**：适用于需要实时数据流处理的业务场景，如实时分析和即时数据更新。
-
-# 批量加载建议
-
-批量摄取涉及加载不需要实时处理的大型有界数据集。这些数据通常以特定的频率被摄取，并非所有数据都立即到达。对于批量加载，建议使用对象存储来存储传入数据。Lakehouse 支持多种文件格式，包括 CSV、Parquet、ORC。

-# Lakehouse Time Travel 功能使用指南
-
-## Time Travel功能简介
-
-Lakehouse 的 Time Travel 功能让您能够轻松访问时间旅行窗口内任何时间点的数据。这意味着您可以在不同的时间点查看数据，甚至可以恢复到先前的数据状态。
-
-借助 Time Travel，您可以查询已更新或删除的数据、恢复已删除的表或者恢复已过期的表。
-![](.topwrite/assets/image_1708936936399.png =740)
-
-如上图所示，表中原来有一条数据，对表执行 INSERT、UPDATE、DELETE 等操作后，一共有四个版本。当指定的时间点或版本在 v0 到 v1 之间时，则会返回 v0 的数据。通过 Time Travel 指定时间点或版本可以查看历史版本数据。
-
-## 访问特定时间点的数据
-
-[TIME TRAVEL](TIMETRAVEL.md)
-
-## 设置数据保留周期
-
-您可以配置 Time Travel 的数据保留周期，以决定数据在时间旅行窗口中保留的时间长度。根据您的需求，您可以设置不同的保留期限。
-
-Time Travel 保留期限决定了您可以访问多久以前的数据。例如，如果 Time Travel 保留期限设置为 7 天，那么您可以访问过去 7 天内任何时间点的数据。如果超过了 7 天，您将无法再使用 Time Travel 访问过期的数据，数据会被物理删除。
-
-当前版本中，默认保留周期是 1 天，可以查询 1 天内的数据。
-
-### 在表上设置数据保留周期
-
-您可以通过以下SQL语句设置表的数据保留周期：
-
-```SQL
-ALTER TABLE orders SET PROPERTIES ('data_retention_days'='num');
-```
-
-其中 `num` 的设置范围为 0-90，表示数据保留的天数。
-
-## 恢复已删除的对象
-
-如果您意外删除了某个对象，可以使用 `UNDROP` 命令来恢复它。以下是一个恢复已删除表的示例：
-
-```SQL
-UNDROP TABLE orders;
-```
-
-此命令将恢复名为 `orders` 的已删除表。
-
-## 恢复到指定版本的数据
-
-使用 `RESTORE` 命令，您可以将数据恢复到特定版本。这对于回滚或修复错误的数据更改非常有用。以下是一个将数据恢复到指定版本的示例：
-
-```SQL
-RESTORE TABLE orders TO TIMESTAMP AS OF '2023-03-01 10:00:00';
-```
-
-此命令将 `orders` 表的数据恢复到 2023年3月1日 10:00:00 的版本。

-# TIMESTAMP\_NTZ
-
-## 概述
-
-timestamp\_ntz即timestamp without time zone 是一种数据库数据类型，用于存储不包含时区信息的日期和时间值。这意味着存储的时间值是绝对的，不考虑时区的变化。无论用户在哪个时区，timestamp without time zone 类型的字段显示的时间都是一样的,使用 timestamp without time zone 类型时，通常需要应用程序或用户自己来管理时区转换，因为数据库不会自动处理时区信息。这种类型适用于那些不需要考虑时区差异的场景。timestamp\_ntz等效于Mysql中的datetime。
-
-## 语法
-
-```SQL
-TIMESTAMP_NTZ
-```
-
-**说明**
-
-`timestamp_ntz` 类型当前支持 JDBC 客户端版本 1.4.0 及以上的 JDBC JAR 包
-
-### timestamp\_ntz常量格式
-
-```SQL

-* `[d]d`：介于 01 和 31 之间的一位数或两位数的日期。
-* `H[H]`：介于 00 和 23 之间的一位数或两位数的小时。
-* `m[m]`：介于 00 和 59 之间的一位数或两位数的分钟。
-* `s[s]`：介于 00 和 59 之间的一位数或两位数的秒。

-+----------------------------+
-| 2021-07-01 08:43:28.123456 |
-+----------------------------+
-```
-
-如果输入的字符串中的格式则会转化为timestmap
-
-## timestamp\_ntz和timestamp\_ltz的区别
-
-timestamp\_ntz（没有时区的时间戳）: 这种类型的时间戳记录的是“墙上时钟”时间，即不考虑任何时区信息的时间。所有的操作都是在没有考虑时区的情况下进行的。如果输出格式包含时区，将显示UTC指示符（Z）。这意味着，无论你在世界上的哪个地方，timestamp\_ntz记录的时间都是相同的。
-
-timestamp\_ltz（本地时区的时间戳）: 这种类型的时间戳在内部存储UTC时间，并根据当前会话的时区进行所有操作。这意味着，当你查询一个timestamp\_ltz类型的字段时，你看到的时间将是转换为你当前会话时区的时间。这使得在全球分布的系统中工作时，用户可以看到转换为他们本地时区的时间。
-
-如下所示：本地客户端的时区为utc+00区。timestamp\_ltz会根据字符输入的时区进行转化内部存储UTC时间，由于客户端也在utc+00区，所以查出来会转化为utc+00时间。而timestamp\_ntz不考虑任何时区所以客户端在任何时区查出来都是该时间
-
-```SQL
-SELECT timestamp_ltz'2022-03-30 06:00:00+08',timestamp_ntz'2022-03-30 06:00:00+08';
-+---------------------------------------+---------------------------------------+
-| timestamp_ltz'2022-03-30 06:00:00+08' | timestamp_ntz'2022-03-30 06:00:00+08' |
-+---------------------------------------+---------------------------------------+
-| 2022-03-29 22:00:00                   | 2022-03-30 06:00:00                   |
-+---------------------------------------+---------------------------------------+
-```
-
-## 约束限制
-
-* 不支持python sdk写入timestamp\_ntz
-
-## 具体案例
-
-1. 将timestmap\_ntz转化为timestmap\_ltz
-
-```SQL
-SELECT cast(timestamp_ntz'2022-03-30 06:00:00' as timestamp_ltz);
-+-------------------------------------------------------+
-| CAST(timestamp_ntz'2022-03-30 06:00:00' AS timestamp) |
-+-------------------------------------------------------+
-| 2022-03-30 06:00:00                                   |
-+-------------------------------------------------------+
-```
-
-2. 将timestmap\_lt转化为timestmap\_ntz
-
-```SQL
-SELECT cast(timestamp_ltz'2022-03-30 06:00:00+08' as timestamp_ntz);
-+--------------------------------------------------------------+
-| CAST(timestamp_ltz'2022-03-30 06:00:00+08' AS timestamp_ntz) |
-+--------------------------------------------------------------+
-| 2022-03-30 06:00:00                                          |
-+--------------------------------------------------------------+
-```
-
-3. 建表时使用timestamp\_ntz字段数据类型
-
-```SQL
-CREATE    TABLE timestamp_wihtout_timezone (col timestamp_ntz);
-```
-
-4. 插入timestamp\_ntz类型数据
-
-```SQL
-INSERT    INTO timestamp_wihtout_timezone
-VALUES    (timestamp_ntz '2022-03-30 06:00:00');
-```
-
-5. 使用函数处理
-
-```SQL
-SELECT    year(timestamp_ntz '2022-03-30 06:00:00');
-+--------------------------------------------+
-| `year`(timestamp_ntz'2022-03-30 06:00:00') |
-+--------------------------------------------+
-| 2022                                       |
-+--------------------------------------------+
-SELECT    month(timestamp_ntz '2022-03-30 06:00:00');
-+---------------------------------------------+
-| `month`(timestamp_ntz'2022-03-30 06:00:00') |
-+---------------------------------------------+
-| 3                                           |
-+---------------------------------------------+

-# 编写SQL对数据进行清洗
-
-在数据分析和数据挖掘的过程中，数据清洗和预处理是至关重要的一步。本文将介绍各种常用的Lakehouse SQL数据清洗方法，帮助您更好地理解和应用这些方法。
-
-## 构建环境
-
-导航到Lakehouse Studio开发->任务，单击“+”新建一个SQL任务（以下两种方式都在同一个任务里实现）。
-
-:-: ![](.topwrite/assets/image_1736148597217.png =470)
-
-^
-
-新建两个SQL任务（如下图所示），然后从[GitHub获取代码](https://github.com/yunqiqiliang/clickzetta_quickstart/tree/main/QuickStart_SQL_DataClean)下载SQL代码并复制到两个任务中。
-
-然后逐一运行每个SQL，观察结果。
-
-:-: ![](.topwrite/assets/image_1736402851987.png =471)
-
-以下是各个步骤的说明。
-
-## 构建实验用的Schema和计算集群
-
-```SQL
--- Data_Clean virtual cluster
-CREATE VCLUSTER IF NOT EXISTS Data_Clean
-   VCLUSTER_SIZE = XSMALL
-   VCLUSTER_TYPE = GENERAL
-   AUTO_SUSPEND_IN_SECOND = 60
-   AUTO_RESUME = TRUE
-   COMMENT  'Data_Clean VCLUSTER for test';
-
--- Use our VCLUSTER
-USE VCLUSTER Data_Clean;
-
--- Create and Use SCHEMA
-CREATE SCHEMA IF NOT EXISTS  Data_Clean;
-USE SCHEMA Data_Clean;
-```
-
-> 注：计算集群的vcluster\_size参数同时支持以T-shirt size（XSMALL、SMALL、Large等）和以数字（1,2,4,16等）表达的方式，以提供更丰富的计算集群规格，满足不同场景的需要。更多信息详见：[计算集群规格代码变更说明](vcluster_size_description.md)
-
-## 将IDE中每个任务的Schema和集群设置为新创建的：
-
-:-: ![](.topwrite/assets/image_1736403086331.png =508)
-
-^
-
-## 创建示例表并插入脏数据
-
-首先，我们需要创建一个示例表，并插入一些包含脏数据的示例数据，以便在接下来的步骤中进行演示。
-
-```SQL
--- 创建名为 "sales_data" 的示例表
-CREATE TABLE sales_data (
-    id INT,
-    sale_date DATE,
-    customer_id INT,
-    product_id VARCHAR(50),
-    quantity INT,
-    price DECIMAL(10, 2),
-    total_amount DECIMAL(10, 2),
-    region VARCHAR(50)
-);
-
--- 插入20行包含脏数据的示例数据
-INSERT INTO sales_data (id, sale_date, customer_id, product_id, quantity, price, total_amount, region) VALUES
-(1, '2025-01-01', 101, '201A', 5, 100.00, 500.00, 'North'),
-(2, '2025-01-02', 102, '202', 3, 150.00, 450.00, 'East'),

-
-## 处理缺失值
-
-### 说明
-
-缺失值是数据清洗中常见的问题，它会导致数据分析结果不准确。可以使用 `COALESCE` 函数、`IFNULL` 函数或者 `CASE` 语句填充默认值或替换缺失值。在实际项目中，处理缺失值常用于确保关键字段不为空，以保证数据的完整性。
-
-### 实现
-
-```sql
--- 使用 COALESCE 填充默认值
-SELECT id, sale_date, COALESCE(customer_id, 0) AS customer_id, product_id, quantity, price, COALESCE(total_amount, 0) AS total_amount, region FROM sales_data;
-
--- 使用 IFNULL 填充默认值
-SELECT id, sale_date, IFNULL(customer_id, 0) AS customer_id, product_id, quantity, price, IFNULL(total_amount, 0) AS total_amount, region FROM sales_data;
-
--- 使用 CASE 语句处理缺失值
-SELECT id, 
-       CASE 
-           WHEN sale_date IS NULL THEN '2025-01-01'
-           ELSE sale_date
-       END AS sale_date,
-       customer_id, 
-       product_id, 
-       quantity, 
-       price, 
-       total_amount, 
-       region 
-FROM sales_data;
-
-```
-
-## 移除特殊字符
-
-### 说明
-
-特殊字符会影响数据的分析，可以使用 `REGEXP_REPLACE` 函数来移除这些字符。在实际项目中，移除特殊字符常用于清理文本字段中的噪声字符，使数据更加整洁和规范。
-
-### 实现
-
-```sql
--- 移除特殊字符
-SELECT id, sale_date, customer_id, 
-       REGEXP_REPLACE(product_id, '[^a-zA-Z0-9]', '') AS cleaned_product_id,
-       quantity, 
-       price, 
-       total_amount, 
-       region
-FROM sales_data;
-```
-
-## 转换数据类型
-
-### 说明
-
-有时候需要将数据从一种类型转换为另一种类型，例如将字符串转换为日期类型。数据类型的转换能够保证数据的一致性和准确性。在实际项目中，常用于标准化数据格式，如日期、金额等。
-
-### 实现
-
-```sql
--- 将字符串转换为日期
-SELECT id, CAST(sale_date AS DATE) AS sale_date, 
-    customer_id, product_id, quantity, 
-    CAST(price AS DECIMAL(10, 2)) AS price, 
-    CAST(total_amount AS DECIMAL(10, 2)) AS total_amount, region 
-FROM sales_data;
-```
-
-## 删除空格
-
-### 说明
-
-在数据清洗过程中，字符串前后的空格会导致数据分析结果不准确。我们可以使用 `TRIM` 函数删除空格。在实际项目中，删除空格常用于清理包含多余空格的文本字段。
-
-### 实现
-
-```sql
--- 删除空白值
-SELECT id, 
-       TRIM(sale_date) AS sale_date, 
-       customer_id, 
-       product_id, 
-       quantity, 
-       price, 
-       total_amount, 
-       TRIM(region) AS region
-FROM sales_data;
-```
-
-## 转换大小写
-
-### 说明
-
-为了统一数据格式，可以将文本字段转换为小写或大写。在实际项目中，转换大小写常用于确保数据的一致性，例如在客户名称、产品名称等字段中。
-
-### 实现
-
-```sql
--- 将区域字段转换为小写
-SELECT id, 
-       sale_date, 
-       customer_id, 
-       product_id, 
-       quantity, 
-       price, 
-       total_amount, 
-       LOWER(region) AS region
-FROM sales_data;
-```
-
-## 删除异常值
-
-### 说明
-
-异常值可能会影响数据分析的结果，使用 `DELETE` 语句可以删除这些记录。在实际项目中，删除异常值常用于剔除极端或错误的数据，以保证分析结果的准确性。
-
-### 实现
-
-< -5000;
-```
-
-## 去重
-
-### 说明
-
-在数据集中，重复记录会影响数据分析的准确性。我们可以使用 `DISTINCT` 或者 `ROW_NUMBER()` 函数来去除重复记录。在实际项目中，去重操作常用于合并多个数据源或清理历史数据时。
-
-### 实现
-
-```sql
--- 使用 DISTINCT 去重
-SELECT DISTINCT customer_id, product_id, region FROM sales_data;
-
--- 使用 ROW_NUMBER() 去重
-WITH RowNumCTE AS (
-    SELECT *,
-           ROW_NUMBER() OVER(PARTITION BY customer_id, product_id, region ORDER BY id) AS row_num
-    FROM sales_data
-)
-SELECT id, sale_date, customer_id, product_id, quantity, price, total_amount, region
-FROM RowNumCTE
-WHERE row_num = 1;
-```
-
-## 数据分组和聚合
-
-### 说明
-
-通过分组和聚合，可以生成汇总报告，了解数据的整体情况。分组和聚合操作可以帮助我们发现数据中的模式和趋势。在实际项目中，常用于统计、分析数据，如计算销售总额、平均值等。
-
-### 实现
-
-```sql
--- 按区域分组计算总销售额
-SELECT region, SUM(total_amount) AS total_sales FROM sales_data GROUP BY region;
-
--- 按产品分组计算总销售量
-SELECT product_id, SUM(quantity) AS total_quantity FROM sales_data GROUP BY product_id;
-```
-
-## 数据筛选
-
-### 说明
-
-使用 `WHERE` 子句筛选出符合特定条件的数据。在实际项目中，数据筛选常用于提取感兴趣的数据子集，如筛选出高价值客户、特定时间段的销售数据等。
-
-### 实现
-
-```sql
--- 筛选出销售金额大于500的记录
-SELECT * FROM sales_data WHERE total_amount >
-
-## 数据排序
-
-### 说明
-
-排序可以帮助我们按特定顺序查看数据，发现数据中的模式和趋势。在实际项目中，排序常用于数据展示、报告生成等场景。
-
-### 实现
-
-```sql
--- 按销售金额排序
-SELECT * FROM sales_data ORDER BY total_amount DESC;
-```
-
-## 合并列数据
-
-### 说明
-
-在某些情况下，我们需要将多个列的数据合并为一列。在实际项目中，合并列数据常用于生成综合信息字段，例如完整的地址、姓名等。
-
-### 实现
-
-```sql
--- 合并产品ID和区域字段
-SELECT id,       sale_date,       customer_id,       product_id || '-' || region AS combined_field,       quantity,       price,       total_amountFROM sales_data;
-```
-
-## 合并数据
-
-### 说明
-
-使用 `UNION` 操作将多个结果集合并在一起，形成一个完整的结果集。在实际项目中，合并数据常用于将多个查询结果整合在一起，形成统一的分析数据集。
-
-### 实现
-
-```sql
--- 合并两个结果集
-SELECT id, sale_date, customer_id, product_id, quantity, price, total_amount, region FROM sales_data
-UNION
-SELECT id, sale_date, customer_id, product_id, quantity, price, total_amount, region FROM another_sales_data;
-```
-
-通过以上的SQL数据清洗和预处理技术，您可以有效地处理和转换数据，为后续的数据分析和挖掘奠定坚实的基础。数据清洗不仅能提高数据质量，还能提升数据分析的准确性和可靠性。

-# 数据结果探查
-
-数据结果探查功能帮助用户在SQL查询结果的基础上，快速分析字段的基础统计特征、数据分布和质量情况，适用于数据清洗、质量检查、探索性分析等场景。
-
-## 使用探查功能
-
-操作入口：开发功能下，点击SQL开发，并在该节点上创建一个数据查询分析的脚本。点击运行结果的数据TAB后，默认在结果页面的最右侧会呈现探查功能板块。或点击右侧「探查」功能。
-![](.topwrite/assets/image_1741749786774.png =163)
-
-> 注意：数据探查仅是针对前端呈现的结果数据做的部分探查。暂不支持超出前端执行结果部分的全量数据探查
-
-例如：当执行结果总量为2万行，但是前端只呈现了1万行数据，那么探查结果是针对前端呈现的1万条数据的可视化探查。
-
-探查功能会基于查询结果的字段信息，给出字段填充率以及字段数值分布的信息。
-
-* 填充率：即统计字段里有具体数值、NULL、以及空字符的具体占比。
-* 空字符：统计当前字段数值里 = “ ” 的统计占比
-* Null：统计前字段数值里 is null的统计占比
-* 有数据：统计当前字段是正常有数据的占比情况。
-* 字段数值分布：按照字段类型列出数值分布情况。其中若字段是数值类型，则会给出数值的sum以及avg的信息。

-# Lakehouse Data Share 跨账号数据共享入门指导
-
-## 1. 方案概述
-
-### 1.1 什么是Data Share
-
-Data Share是Lakehouse提供的**无复制数据共享功能**，可在同一服务区域内实现**跨账户或跨服务实例**的数据授权与使用。与传统的数据复制或导入方案不同，Data Share不需要在企业间手动搭建数据同步链路，而是通过"授权"方式直接提供对源数据的只读访问，且实时更新。
-
-### 1.2 核心优势
-
-* **无复制、低延迟**：无需在企业间重复存储或定期同步，数据变更可以实时传播给消费方
-* **安全可控**：数据仅以"只读"形式分享，且随时可通过权限管控移除共享对象
-* **易于扩展**：通过View可以灵活过滤数据列或行，实现精细化的分享控制
-* **降低成本**：消费方无需为被分享的数据存储付费，仅需使用自己的计算资源处理数据
-
-### 1.3 适用场景
-
-* **实时共享场景**：企业A将交易日志、用户行为数据等实时共享给企业B，企业B无需数据同步即可实时查询
-* **多方协作分析**：多家合作方基于同一份实时数据进行分析，减少重复存储和传输成本
-* **数据提供商与消费者模式**：数据提供方将部分数据开放给合作伙伴，消费方无需承担存储成本即可获得只读数据
-
-## 2. 工作原理
-
-Data Share的核心工作原理是：
-
-1. **数据保留在提供方**：数据始终存储在数据提供方的账户中
-2. **共享元数据**：共享元数据和访问权限给消费方
-3. **访问控制**：消费方通过受控的只读访问权限查询数据
-4. **实时更新**：提供方的数据更新后，消费方立即能访问到最新数据
-
-**数据共享流程**：
-
-:-: ![](.topwrite/assets/image_1747735731291.png =322)
-
-数据提供方保留完全的控制权，可以随时更新或移除共享数据。当源数据更新时，消费方可立即获取最新数据，无需额外的数据同步操作。
-
-## 3. 使用前提条件
-
-* 数据提供方和数据消费方均需有Lakehouse实例
-* 双方需在同一服务区域内
-* 数据提供方需具备"实例管理员"(instance\_admin)角色权限
-* 数据共享操作需要消费方提供其服务实例名称
-
-## 4. 实操指南：数据提供方
-
-### 4.1 创建分享对象
-
-数据提供方（数据所有者）需要执行以下步骤创建并配置分享对象：
-
-#### 4.1.1 SQL方式
-
-```sql
--- 步骤1：创建Share对象
-CREATE SHARE taxi_data_share;
-
--- 步骤2：将表添加到Share对象中
-GRANT SELECT, READ METADATA ON TABLE demo_schema.taxi_zone_lookup TO SHARE taxi_data_share;
-
--- 步骤3：指定接收实例
-ALTER SHARE taxi_data_share ADD INSTANCE target_instance_name;
-```
-
-#### 4.1.2 Web界面方式
-
-1. 使用具备"实例管理员"角色的账号登录Lakehouse控制台
-2. 左侧导航选择"数据管理" → "数据分享"，点击"+新增分享"
-3. 填写分享名称（如taxi\_data\_share），选择工作空间
-4. 点击"添加"选择要分享的数据对象（如taxi\_zone\_lookup表）
-5. 点击"接收实例"下的"添加"，输入消费方提供的服务实例名称
-6. 点击"确定"完成创建
-
-:-: ![](.topwrite/assets/image_1747742254855.png =699)
-
-#### 4.1.3 针对部分数据创建视图再共享
-
-如果只需要共享表的部分数据，可以先创建视图，然后共享视图：
-
-```sql
--- 创建专用schema用于管理分享视图
-CREATE SCHEMA share_views;
-
--- 创建筛选数据的视图
-CREATE VIEW share_views.filtered_taxi_zones AS 
-SELECT * FROM demo_schema.taxi_zone_lookup 
-WHERE borough = 'Manhattan';
-
--- 共享视图
-GRANT SELECT, READ METADATA ON VIEW share_views.filtered_taxi_zones TO SHARE taxi_data_share;
-```
-
-### 4.2 验证分享配置
-
-创建并配置完成后，可以通过以下命令验证分享是否正确配置：
-
-```sql
--- 查看所有Share对象
-SHOW SHARES;
-
--- 查看特定Share的详细信息
-DESC SHARE taxi_data_share;
-```
-
-示例输出：
-
-```
-share_name       provider     provider_instance    provider_workspace  scope    to_instance        kind
----------------------------------------------------------------------------------------------
-taxi_data_share  provider_instance_name  source_instance_name   source_workspace    PRIVATE  target_instance_name OUTBOUND
-```
-
-## 5. 实操指南：数据消费方
-
-数据消费方（接收方）需要执行以下步骤来访问共享数据：
-
-### 5.1 查看可用共享
-
-#### 5.1.1 SQL方式
-
-```sql
--- 查看所有可见的Share
-SHOW SHARES;
-```
-
-示例输出（从消费方实例查看）：
-
-```
-share_name       provider     provider_instance    provider_workspace  scope    to_instance  kind
----------------------------------------------------------------------------------
-taxi_data_share  provider_instance_name  source_instance_name   source_workspace    PRIVATE             INBOUND
-```
-
-```sql
--- 查看Share对象中包含的数据对象
-DESC SHARE source_instance_name.taxi_data_share;
-```
-
-#### 5.1.2 Web界面方式
-
-1. 登录数据消费方的Lakehouse控制台
-2. 左侧导航选择"数据管理" → "数据分享"
-3. 切换到"分享给我"页签，即可看到所有接收到的分享
-
-:-: ![](.topwrite/assets/image_1747742432405.png =757)
-
-### 5.2 创建本地Schema关联共享数据
-
-#### 5.2.1 SQL方式
-
-```sql
--- 创建本地Schema映射到共享数据
-CREATE SCHEMA shared_taxi_data FROM SHARE source_instance_name.taxi_data_share.source_schema;
-```
-
-其中：
-
-* `shared_taxi_data`：在本地创建的schema名称（可自定义）
-* `source_instance_name`：提供方的实例名称
-* `taxi_data_share`：分享对象名称
-* `source_schema`：提供方的源schema名称
-
-#### 5.2.2 Web界面方式
-
-1. 在"分享给我"页签中找到目标分享对象
-2. 点击"提取"按钮
-3. 在弹窗中选择"源schema"，并指定在本地创建的schema名称
-4. 点击"确定"完成提取
-
-:-: ![](.topwrite/assets/image_1747742473685.png =373)
-
-### 5.3 使用共享数据
-
-创建schema后，共享数据将以只读方式出现在本地schema中：
-
-```sql
--- 查询共享表数据
-SELECT * FROM shared_taxi_data.taxi_zone_lookup LIMIT 5;
-
--- 创建分析视图
-CREATE VIEW my_analysis AS
-SELECT borough, COUNT(*) as zone_count
-FROM shared_taxi_data.taxi_zone_lookup
-GROUP BY borough;
-
--- 与本地数据关联分析
-SELECT t.*, z.borough, z.zone
-FROM my_local_table t
-JOIN shared_taxi_data.taxi_zone_lookup z ON t.location_id = z.locationid;
-```
-
-## 6. 完整案例：跨账号共享出租车区域数据
-
-### 6.1 背景场景
-
-A公司运营纽约市出租车服务并维护`taxi_zone_lookup`表，包含所有区域信息。B公司是一家分析公司，需要访问这些区域数据进行分析，但不需要复制数据。
-
-### 6.2 实施步骤
-
-#### 6.2.1 查看源表数据
-
-首先，A公司查看要共享的表结构：
-
-```sql
-DESC TABLE EXTENDED demo_schema.taxi_zone_lookup;
-```
-
-结果显示表结构如下：
-
-```
-column_name  data_type  comment
-----------------------------------
-locationid   bigint     PULocationID or DOLocationID
-borough      string     
-zone         string     
-service_zone string     
-```
-
-表中包含265行数据，记录了纽约市出租车区域信息。
-
-#### 6.2.2 创建分享对象
-
-A公司创建分享对象并配置：
-
-```sql
--- 创建Share对象
-CREATE SHARE taxi_data_share;
-
--- 添加表到Share
-GRANT SELECT, READ METADATA ON TABLE demo_schema.taxi_zone_lookup TO SHARE taxi_data_share;
-
--- 指定B公司的实例作为接收方
-ALTER SHARE taxi_data_share ADD INSTANCE target_instance_name;
-```
-
-#### 6.2.3 验证分享配置
-
-A公司验证分享配置是否正确：
-
-```sql
-DESC SHARE taxi_data_share;
-```
-
-输出结果显示：
-
-```
-kind      name                                shared_on
--------------------------------------------------------
-WORKSPACE <WS>                                2025-05-15 20:37:58.13
-SCHEMA    <WS>.demo_schema                    2025-05-15 20:38:02.018
-TABLE     <WS>.demo_schema.taxi_zone_lookup   2025-05-15 20:38:02.018
-```
-
-```sql
-SHOW SHARES;
-```
-
-输出结果包含新创建的分享：
-
-```
-share_name       provider     provider_instance    provider_workspace  scope    to_instance        kind
---------------------------------------------------------------------------------------
-taxi_data_share  provider_instance_name  source_instance_name   source_workspace    PRIVATE  target_instance_name OUTBOUND
-```
-
-#### 6.2.4 B公司访问共享数据
-
-B公司（实例target\_instance\_name）执行以下操作使用共享数据：
-
-```sql
--- 查看可用分享
-SHOW SHARES;
-
--- 查看分享内容
-DESC SHARE source_instance_name.taxi_data_share;
-
--- 创建本地Schema
-CREATE SCHEMA taxi_data FROM SHARE source_instance_name.taxi_data_share.demo_schema;
-
--- 查询数据
-SELECT borough, COUNT(*) as zone_count 
-FROM taxi_data.taxi_zone_lookup 
-GROUP BY borough 
-ORDER BY zone_count DESC;
-```
-
-B公司可以查询结果并创建报表，无需复制数据。当A公司更新原表数据时，B公司会立即看到最新数据。
-
-## 7. 最佳实践
-
-### 7.1 安全性最佳实践
-
-* **使用视图限制敏感数据**：通过视图筛选行或列，确保只共享必要数据
-* **定期审计共享对象**：使用`SHOW SHARES`和`DESC SHARE`命令定期检查共享内容
-* **最小权限原则**：只授予必要的权限（SELECT和READ METADATA）
-* **不要分享凭证**：严禁共享管理员账号，使用Data Share进行安全的数据共享
-
-### 7.2 性能与成本优化
-
-* **使用筛选视图**：通过视图限制数据量，提高查询性能
-* **注意时区设置**：确保提供方和消费方使用相同的时区设置，避免时间相关查询问题
-
-## 8. 常见问题与故障排除
-
-### 问题1：无法看到共享数据
-
-**可能原因**：
-* 权限配置错误，例如未授予 `READ METADATA` 权限。
-* 实例名称输入有误。
-
-**解决方法**：
-* 提供方使用 `SHOW GRANTS TO SHARE` 命令，检查 share 中共享的对象是否同时被授予了 `SELECT` 和 `READ METADATA` 权限。
-* 验证实例名称是否正确。
-
-### 问题2：无法查询共享数据
-
-**可能原因**：
-* 缺少SELECT权限
-
-**解决方法**：
-
-```sql
-GRANT SELECT ON TABLE <table_name> TO SHARE <share_name>;
-```

-# 数据可视化
-
-本文介绍如何使用云器产品中的图表将 SQL 工作表结果可视化。图表可将查询结果可视化，传达逻辑关系，并帮助您做出更明智的决策。图表可让您快速了解数据中的模式并识别其中的异常值。
-
-当前支持的图表类型有：
-
-* 折线图
-* 柱形图
-
-## 创建图表
-
-在开发中运行查询时，可以根据结果显示图表。
-
-1. 点击开发或工作区，新建/选择一个SQL任务
-2. 执行Select查询任务
-3. 在查询结果的数据tab下，点击「图表」。
-
-## 修改图表
-
-如果您点击「图表」来可视化工作表结果，首先需要基于图表类型，筛选出必选的字段后，可视化区域才会出现相应的图表。
-
-鼠标悬浮在图表上，可查看每个数据点的详细信息。例如，您可以折线图形式查看结果：
-
-![](.topwrite/assets/image_1742200992399.png =757)
-
-^
-
-在可视化右侧区域的「设置」下，筛选需要呈现的信息：
-
-1.图标类型：折线图、柱形图
-
-2.X轴字段：可视化呈现的数值在趋势图上的呈现趋势。
-
-注意：当前不支持按照X轴所选的字段进行聚合。
-
-3.Y轴字段：
-
-![](.topwrite/assets/image_1742201014009.png =347)
-
-Y轴支持使用聚合函数从多个数据点中确定单个值。这些统计方式对应的函数如下：
-
-* 总计：sum
-* 计数：count
-* 均值：average
-* 最大值：maximum
-* 最小值：minimum
-
-4\. 添加Y轴、或分组
-
-最多支持添加10个Y轴的字段放在同一个表格上进行分析；
-
-添加分组即是将已添加到Y轴的字段进行一个group by的操作。
-
-注：当只有一个Y轴时，才允许选择分组字段，同时分组字段只允许选择一个。
-
-## 已知局限
-
-若X轴数值过多时，若需要看到某个趋势上的一个具体数值，建议将图表上的范围缩短后才可以查看到准确的数据点。
-
-例如下图：当鼠标悬浮在可视化图表上，呈现出具体的时间戳信息时，才是准确的数值。
-
-![](.topwrite/assets/image_1742201080540.png =387)
-
-^
-
-## 使用案例
-
-基于时间的趋势图
-
-场景一：如果要保留时间跨度的差异，结果数据类型需要是时间类型，如下：
-
-* order\_date是一个时间戳类型，趋势图会自动按时间间隔实际情况展现数据，这样更能准确体现“趋势”
-
-```
-select order_date, count(*) as c from big_data_table group by order_date;
-```
-
-![](.topwrite/assets/20250317-190632.jpeg =617)
-
-^
-
-![](.topwrite/assets/20250317-190714.jpeg =607)
-
-^
-
-![](.topwrite/assets/20250317-190759.jpeg =608)
-
-^
-
-场景二：如果要**忽略**时间跨度的差异，只保留具体结果点位，结果数据类型转换为string即可（order\_date::string），如下
-
-```
-select order_date::string, count(*) as c from big_data_table group by order_date;
-```
-
-![](.topwrite/assets/20250317-190854.jpeg =654)

-## 环境配置
-
-### **重要说明：配置必须严格按照以下顺序执行**
-
-```
-配置依赖关系和顺序：
-1. Account级别：Service Principal创建和配置
-2. Account级别：Unity Catalog Metastore External Data Access启用
-3. Account级别：Storage Credential和External Location配置
-4. Workspace级别：Catalog和Schema创建
-5. Workspace级别：Service Principal权限配置
-6. 端到端测试和验证
-```
-
-### 1. Databricks 关键配置
-
-#### 1.1 Service Principal创建和配置
-
-**步骤1：创建Service Principal（Account Console操作）**
-
-1. 登录 **Databricks Account Console**（注意：不是workspace）
-2. 导航路径：`Account settings` → `User management` → `Service principals`
-3. 点击 `Add service principal`
-4. 填写配置：
-   * **Display name**: `Lakehouse-Integration-SP`
-   * **Application ID**: 自动生成（**重要：记录此CLIENT\_ID**）
-5. 点击 `Add` 创建
-
-**步骤2：生成 Secret（Account Console 操作）**
-
-1. 进入创建的 Service Principal 详情页
-2. 点击 `Secrets` tab
-3. 点击 `Generate secret`
-4. **重要**：立即复制并安全保存 Secret 值（只显示一次）
-5. 记录以下信息用于云器连接：
-   ```
-   CLIENT_ID
-   CLIENT_SECRET
-   ```
-
-**步骤3：分配 workspace 权限（Account Console 操作）**
-
-1. 在Account Console中，导航到 `Workspaces`
-2. 选择目标workspace
-3. 点击 `Permissions` tab
-4. 点击 `Add permissions`
-5. 搜索并选择创建的 Service Principal
-6. 分配权限：`Admin`（推荐用于初始配置，后续可调整为User）
-
-#### 1.2 Unity Catalog Metastore 配置
-
-**步骤1：检查Metastore状态（Workspace SQL编辑器）**
-
-```sql
--- 在Databricks workspace中执行
-DESCRIBE METASTORE;
-
--- 检查输出中的关键信息：
--- Metastore Name: metastore名称
--- Cloud: 应该是 'aws'
--- Region: 应该与云器相同
--- Privileged Model Version: 应该是 '1.0' 或更高
-```
-
-**步骤2：启用External Data Access（Account Console操作）**
-
-1. 在 Databricks 工作区左侧的主导航栏中，点击 `Catalog\` 选项进入 Catalog Explorer。
-2. 在 Catalog Explorer 的主界面上方，点击齿轮形状的设置图标 (Manage)。
-3. 在弹出的下拉菜单中，点击 `Metastore\` 选项。
-4. 在 Metastore 页面确保以下选项已启用：
-   ```
-   ✅ External data access: Enabled
-   ```
-
-**步骤3：Service Principal 权限配置**
-
-1. 进入 Databricks Workspace Console。
-
-* 在左侧边栏中，点击 `Catalog` 进入 Catalog 浏览器。&#x20;
-* 在 Catalog 列表中，点击您希望授权的目标 Catalog，例如 `databricks_catalog`。&#x20;
-
-2\. 打开权限管理
-
-* 在所选 Catalog 的主页面中，点击 Permissions 标签页。&#x20;
-* 点击 Grant 按钮以打开授权对话框。&#x20;
-
-3\. 选择主体 (Principal)&#x20;
-
-* 在弹出的 Grant on <Catalog 名称> 对话框中，于 Principals 字段搜索并选择您的服务主体。
-
-4\. 分配权限
-
-* 使用权限预设 (Privilege presets)：为了简化配置，建议使用预设角色。对于需要读写和创建对象的场景，从下拉菜单中选择 Data Editor。此预设会自动授予一系列常用权限，如 `USE CATALOG, USE SCHEMA, SELECT, MODIFY, CREATE TABLE` 等。
-* 授予外部访问权限 (关键步骤)：如果您需要允许外部系统（非 Databricks）通过此服务主体访问数据，请务必勾选页面底部的` EXTERNAL USE SCHEMA` 权限。此权限是允许外部引擎访问此 Catalog 中 Schema 的关键。&#x20;
-
-5\. 确认授权：检查所选的权限配置无误后，点击 `Confirm` 按钮完成授权。
-
-### 2. 云器 Lakehouse 环境配置
-
-#### 2.1 环境准备检查
-
-**环境要求确认**：
-
-*   ✅ **必选**：AWS 环境的云器 Lakehouse
-*   ✅ **推荐**：与 Databricks 相同 AWS 区域部署
-
-#### 步骤1：建立Catalog连接
-
-```sql
--- 在云器 Lakehouse 中执行
-CREATE CATALOG CONNECTION IF NOT EXISTS databricks_aws_conn
-TYPE DATABRICKS
-HOST = 'https://dbc-91642d78-eab3.cloud.databricks.com/'  -- Databricks 工作空间的URL
-CLIENT_ID = 'your-service-principal-id'
-CLIENT_SECRET = 'your-service-principal-secret'
-ACCESS_REGION = 'us-west-2'
-COMMENT = 'Databricks Unity Catalog 企业级连接';
-```
-
-#### 步骤2：创建External Catalog
-
-```sql
--- 在云器 Lakehouse 中执行
-CREATE EXTERNAL CATALOG databricks_catalog 
-CONNECTION databricks_aws_conn 
-OPTIONS (
-    'catalog' = 'datagpt_catalog'  -- 目标的 Catalog 名称（不是 Metastore 名称）
-);
-```
-
-#### 步骤3：验证连通性
-
-```
--- 展示 Catalog 中的 Databricks 的 Schema 信息
-SHOW SCHEMAS IN databricks_catalog;
-
--- 展示 Databricks default Schema 下的表信息
-SHOW TABLES in databricks_catalog.default;
-
--- 查询从 Databricks 表的数据
-SELECT * FROM databricks_catalog.<databricks_schema>.<databricks_table> LIMIT 100;
-
-```

-
--- 查看是否有EXTERNAL USE权限
-SELECT 
-    grantee,
-    privilege_type,
-    object_type
-FROM system.information_schema.grants 
-WHERE grantee = 'your-application-id'
-AND privilege_type = 'EXTERNAL_USE';
-```
-
-**解决方案**：
-
-```sql
--- 重新配置EXTERNAL USE SCHEMA权限
-GRANT EXTERNAL USE SCHEMA ON SCHEMA enterprise_catalog.core_data 
-TO SERVICE_PRINCIPAL 'your-application-id';
-```
-
-#### 场景：外部表访问失败
-
-```
-错误信息：TABLE_DB_STORAGE cannot be accessed externally
-```
-
-**根本原因分析**：
-
-* 表创建时未指定外部存储位置
-* 即使使用`USING DELTA`，缺少`LOCATION`子句会创建内部存储表
-
-**企业级解决方案**：
-
-```sql
--- 在Databricks中重新设计表架构
-CREATE TABLE enterprise_catalog.core_data.table_name_v2 (
-    -- 列定义
-    column1 INT,
-    column2 STRING
-) 
-USING DELTA 
-LOCATION 's3://enterprise-data-lake/core/table_name_v2/';
-
--- 数据迁移策略
-INSERT INTO enterprise_catalog.core_data.table_name_v2 
-SELECT * FROM enterprise_catalog.core_data.table_name_v1;
-
--- 验证表类型
-SHOW TABLE EXTENDED enterprise_catalog.core_data.table_name_v2;
-```
-
-### 2. 连接配置问题
-
-#### 场景：Service Principal认证失败
-
-```
-错误信息：Authentication failed for service principal
-```
-
-**企业级排查清单**：
-
-* [ ] 确认 CLIENT_ID 和 CLIENT_SECRET 正确
-* [ ] 验证Service Principal在Account Console中存在
-* [ ] 检查Service Principal的workspace权限
-* [ ] 确认Unity Catalog External Data Access已启用
-
-**解决步骤**：
-
-```sql
--- 1. 在Databricks中验证Service Principal
-SELECT current_user() as current_principal;
-
--- 2. 检查workspace访问权限（在Account Console中操作）
-
--- 3. 重新生成Secret（如需要）
--- 在Account Console → Service Principal → Secrets → Generate secret
-
--- 4. 在云器中更新连接信息
-ALTER CONNECTION databricks_aws_conn 
-SET CLIENT_SECRET = 'new-secret-value';
-```
-
-### 3. 存储访问问题
-
-#### 场景：S3存储位置无法访问
-
-```
-错误信息：Access denied to S3 location
-```
-
-**排查步骤**：
-
-```sql
--- Databricks端测试存储访问
-LIST 's3://your-bucket/external-tables/';
-
--- 检查Storage Credential配置
-DESCRIBE STORAGE CREDENTIAL enterprise_s3_credential;
-
--- 检查External Location配置
-DESCRIBE EXTERNAL LOCATION enterprise_external_tables;
-```
-
-**解决方案**：
-
-```json
-// 检查IAM Role Policy配置
-{
-    "Version": "2012-10-17",
-    "Statement": [
-        {
-            "Effect": "Allow",
-            "Action": [
-                "s3:GetObject",
-                "s3:PutObject",
-                "s3:DeleteObject",
-                "s3:ListBucket",
-                "s3:GetBucketLocation"
-            ],
-            "Resource": [
-                "arn:aws:s3:::your-bucket",
-                "arn:aws:s3:::your-bucket/*"
-            ]
-        }
-    ]
-}

-# 如何让 DataGPT 回答得更准确
-
-作为一个基于数据的问答系统，回答的准确性尤为重要。系统提供以下手段来保障准确性：
-
-## 1.数据治理
-
-* **数据画像**（DataGPT Profile）：系统提供数据画像功能，让您了解底层数据集表的数据状态。通过 **左侧导航栏 -> 数据 -> 数据表**，在表详情页的 **统计分析** 页签，可以查看数据状态，帮助您进行数据治理。建立数据画像，也有助于通过自然语言找到合适的目标数据。
-
-> 注意：DataGPT 仅提供数据的 **统计分析** 功能，供客户查看数据分布、进行统计分析。数据质量由上游数据平台保证。
-
-* **表、列描述与列别名配置**：为表和列添加准确的描述和别名信息，这有助于系统精确地将问题与数据做匹配。在 **左侧导航栏 -> 数据 -> 数据表** 中，可以分别配置表级别的描述、列的别名（Alias）和列的描述（Description）。数据表和列有清晰准确的别名和描述，不同表和列在名称和描述上的歧义越小，回答的准确度越高。
-
-* **列类型与用途**：请根据列的实际含义填写列类型（ColumnType）与用途（Intended For）。**该选项会影响系统是否选择该列作为数据来源**。
-
-## 2. 划分分析域
-
-拆分业务域（或分析域）有助于系统更加聚焦于特定数据。
-
-1. 预先划分分析域，减少每个 Domain 里涉及的数据表范围和知识范围。
-2. 针对域（Domain）提问更为聚焦，同时域会绑定用户，能做到表级别的数据隔离。
-
-## 3. 创建指标与答案构建器
-
-指标是聚合函数或基于聚合函数的计算结果，答案构建器是基于 SQL 的模板定义，两者均为预定义对象。基于指标和答案构建器进行回答，会使准确率大幅提升。如果对问答准确率有严格要求，建议预先定义好它们。指标支持别名，用于匹配更多的表达方式。请参考[指标与答案构建器](metrics_answer_build.md)
-
-:-: ![](.topwrite/assets/image_1736900144814.png =636)
-
-## 4. 采用输入提示
-
-**列值智能匹配**：启用列值索引功能后，系统将在您输入时提供实时数据值提示，以确保查询结果的准确性与相关性。

-# 数据湖常见问题 FAQ
-
-#### **问题1**：**用 PUT 命令上传文件到 Volume 路径之后，在 SQL 处理时，查询不到文件**
-
-**解答**：如果创建 Volume 对象时开启了文件目录表( `DIRECTORY = (enable = TRUE` ) ， 则在向该 Volume 路径中添加新文件之后，需要手动同步该变化到 Lakehouse 元数据系统，可以使用命令 `alter volume xxxx refresh; `（该命令需要执行者拥有对该 volume 对象有 alter 权限：`GRANT ALTER ON VOLUME xxxx  TO USER datalake_user;`）
-
-^
-
-#### **问题2**：**查询数据湖 Volume 中文件时，是否支持 CSV 文件为压缩格式**
-
-**解答**：当前版本暂不支持 CSV 压缩格式文件，会在后续版本中支持。
-
-^
-
-#### **问题3：查询 CSV 文件时报错**：**CZLH-00000:CZLH-71001: CZ_SQL_TIMEZONE should exist in context**；
-
-**解答**：需在查询中指定默认时区：在查询 volume 的 select 语句的options 中，添加 `'timeZone' = 'Asia/Shanghai' `的选项，例如：
-
-```
-select * from volume hz_csv_volume (
-  order_id STRING,
-  order_item_id INT,
-  product_id STRING,
-  seller_id STRING,
-  shipping_limit_date TIMESTAMP,
-  price DECIMAL(10,2),
-  freight_value DECIMAL(10,2)
-)using csv 
- options(
-    'header'='true',
-    'sep'=',',
-    'timeZone' = 'Asia/Shanghai'
- ) files('brazil-ecommerce/olist_order_items_dataset.csv');
-```
-
-^
-
-#### **问题4**：**执行远程函数（remote function）时报错**：**CZLH-42000:\[1,8] Semantic analysis exception - function not found**
-
-**解答**：可能原因：
-
-1. 函数是schema 级别对象，请保证执行函数时携带了正确的 schema 信息，如：函数 fc\_orc\_schema 是属于 public schema 下的对象，引用时需携带 schema 信息：`public.fc_orc_schema()`
-2. 目前执行remote function时，需要在 SQL 语句前携带  `set cz.sql.remote.udf.enabled=true; `并一起执行
-
-```
-set cz.sql.remote.udf.enabled = true;
-SELECT public.fc_orc_schema('orc','<url>') as schema_orc;
-```
-
-####
-
-#### **问题5：执行远程函数时报错**：**CZLH-XX000: failed to hook preExecute: urllib3 v2.0 only supports OpenSSL 1.1.1+, currently the 'ssl' module is compiled with 'OpenSSL 1.1.0l 10 Sep 2019'.**
-
-**解答**：python 代码中需要处理文件url 链接时，需要 urllib3 的库版本与 OpenSSL 版本不兼容，可以安装 urllib3 d的1.26.9 版本代替：`pip3 install --upgrade urllib3==1.26.9 -t .`

-# 数据湖权限管理
-
-数据湖权限管理是确保数据安全和合规性的重要组成部分。通过合理的权限管理，您可以确保用户只能访问和操作其所需的数据和资源。数据湖的权限管理主要涉及两个方面：数据访问权限和函数调用权限。具体包括以下几个方面：
-
-1. Volume 对象的权限点与管理
-2. Remote Function 对象的权限点与管理
-
-## Volume 对象权限
-
-对于 Volume 对象，您可以设置以下权限：
-
-* 对象所属 Schema 的权限：CREATE / DROP
-* 对象本身的权限：READ / WRITE / ALTER
-
-### 示例 1：授权新用户访问 Volume
-
-假设您有一个名为 `datalake_user` 的新用户，您希望授权其访问 workspace 空间。首先，授予该用户 workspace_user 角色（该角色具有只读权限）：
-
-```
-GRANT ROLE workspace_user TO USER datalake_user;
-```
-
-接下来，如果您希望允许 `datalake_user` 用户对 Volume 对象进行读取、上传数据以及将文件元数据同步到 Lakehouse 元数据服务，需要进行以下授权：
-
-1. 授权使用计算资源 Virtual Cluster。
-2. 授予用户 `datalake_user` 对 Volume 的 READ、WRITE、ALTER 权限。
-
-具体步骤如下：
-
-```SQL
-GRANT USE VCLUSTER ON VCLUSTER DEFAULT TO USER datalake_user;
-```
-
-```SQL
-GRANT READ ON volume xxx TO USER datalake_user;
-GRANT WRITE ON volume xxx TO USER datalake_user;
-GRANT ALTER ON volume xxx TO USER datalake_user;
-```
-
-## Remote Function 对象权限
-
-对于 Remote Function 对象，您可以设置以下权限：
-
-* 对象所属 Schema 的权限：CREATE / DROP
-* 对象本身的权限：USE
-
-### 示例 2：授权用户使用 Remote Function
-
-假设您希望授权用户 `datalake_user` 使用名为 fc_image_2_text 的 Remote Function，您可以执行以下命令：
-
-```SQL
-GRANT USE ON FUNCTION fc_image_2_text TO USER datalake_user;
-```

-# 数据湖查询
-
-在创建 Volume 对象之后，您可以通过该对象直接查询外部存储路径中的 CSV、Parquet 和 ORC 格式的数据文件，无需依赖任何元数据系统。
-
-## 前提条件
-
-1. 如果数据在云厂商的对象存储中，请先完成创建 Storage Connection 和 External Volume 对象。
-2. 在 Lakehouse 中查询 Volume 中的文件前，请确认是否具备对目标 Volume 对象的读权限（READ）。如果同时需要使用 [PUT 命令](PUT.md) 上传文件，则需要具备读、写权限。可以使用 `show grants to user <user_name>` 查看当前用户是否具备上述权限。
-
-## 使用限制
-
-* 支持的外部存储包括：阿里云 OSS、腾讯云 COS 和 AWS S3。
-* 仅支持查询 CSV、Parquet 和 ORC 三种文件格式。
-* 仅支持 gzip、zstd 和 zlib 三种压缩格式。

-Lakehouse Volume 是在云器 Lakehouse 中表示云对象存储位置的对象。它提供了对云上对象存储的访问、存储、管理和组织文件等功能，可用于存储和访问各种格式的文件，包括结构化、半结构化和非结构化数据。它可以与表、视图等对象一样在Lakehouse 的 Schema 下进行组织和管理。使用 Volume 功能会带来如下收益：
-
-* 统一数据分析：支持在云器 Lakehouse 中调用 AI 负载处理对象存储中的图片、PDF 以及特殊格式的非结构化数据，与平台中的结构化数据做统一处理和分析
-* 统一权限管理：支持使用云器 Lakehouse 平台的权限系统，对库表以及对象存储中的文件做统一权限管理
-* 统一数据治理：对象存储中的数据会被云器 Lakehouse 平台统一管理和治理
-
-Lakehouse Volume按照数据存储位置分为 Internal Volume 和 External Volume 两种类型：
-
-| **特性** | **External Volume**                                                                                                                                    | **Internal Volume**                                                                                                                                                                                                                                                                                                                                   |
-| :----- | :----------------------------------------------------------------------------------------------------------------------------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| 存储位置   | 客户指定的外部存储位置，云器仅保留路径元信息。支持的存储产品有：&#xA;- 阿里云 OSS&#xA;- 腾讯云 COS&#xA;- 亚马逊云 S3&#xA;- 谷歌云 GCS                                                               | 云器账号内部存储，与内表对象共同存储与指定Schema路径下。                                                                                                                                                                                                                                                                                                                       |
-| 使用场景   | 在您已经使用对象存储服务存储和管理数据时，通过 External Volume，云器 Lakehouse 能够 Mount 到已有存储服务，将对象存储视为数据湖以共享已有数据。                                                                 | Internal Volume 默认提供了以下2种Volume对象：&#xA;- Table Volume：数据表默认关联的文件存储区域，权限与数据表权限一致。Table Volume 常用于简化批量导入、导出场景。用户只要对目标表有读写权限，即可直接通过 PUT/GET 方式向目标表默认关联的 Table Volume 目录交换文件，从而简化批量导入/导出场景下对 Volume 的权限要求。&#xA;- User Volume：用户账号关联的文件存储区域，Workspace User 默认对该区域具备管理权限。每个 Workspace 都默认拥有一个具备管理权限的 User Volume，用户可以将各种格式的文件上传至此。Table/User Volume 具备默认权限，不支持额外授权。 |
-| 操作管理   | 创建 External Volume 通过 PUT 命令上传本地文件通过 GET 命令下载文件至本地查看指定 Volume 下文件列表删除指定 Volume 路径下文件使用 COPY INTO 命令导入导出数据使用SQL查询文件数据使用 get\_presigned\_url 函数获取文件访问地址。 | 通过 PUT 命令上传本地文件；删除指定 Volume 路径下文件。                                                                                                                                                                                                                                                                                                                          |
-| 存储费用   | 不属于 Lakehouse 存储计费项目。                                                                                                                                  | 和内表存储相同，属于Lakehouse存储计费项目。                                                                                                                                                                                                                                                                                                                            |

-# DataOps数据安全稳定生产实践
-
-## 概述
-
-DataOps 通过结合敏捷开发、数据管理和数据科学的最佳实践，能够显著提高数据管道的效率和质量。在 DataOps 整个数据研发运营流水线上，数据开发管理和数据运维是两个极为关键的环节。
-
-本实践围绕这两个环节展开，基于 NYC TLC Trip Record Data，构建 pipeline 进行数据清洗和指标统计分析，产出数据供 BI 查询使用。通过本实践，可了解到如下内容：
-
-* 如何便捷地构建定时调度运行的数据处理 pipeline，对数据同步、SQL 任务等进行统一的调度编排。
-* 如何利用监控告警规则，及时监控任务运行的稳定性。
-* 如何利用数据质量监控规则，监控数据产出的正确性，及时告警，防止问题数据扩散。
-* 如何利用完善的运维措施，来快速定位问题原因。
-* 如何提高监控告警的处置效率。
-
-## Pipeline
-
-整个 Pipeline 包含如下五个任务节点：
-
-* 1\_同步\_OSS：从OSS端，批量同步数据，写入到Lakehouse
-* 1\_同步\_Kafka：从Kafka端批量同步数据，写入到Lakehouse
-* 2\_数据清洗：对于源端同步进来的数据进行简单清洗加工、关联维度表进行拓宽
-* 3\_指标计算\_daily汇总：计算关键的业务指标
-* 6\_BI\_简单查询：使用SQL模拟BI查询的简单示意
-  ![](.topwrite/assets/image_1715856764265.png =414)
-
-## 主要步骤
-
-### 任务开发调度和提交发布运行
-
-使用 **任务开发** 模块的功能来编排整个 pipeline：首先进行数据同步导入，然后编写 SQL 代码进行数据清洗，按天维度统计出行数据、计算平均每单金额和平均乘客数等指标，最后供 BI 报表查询。
-
-#### 任务开发
-
-在任务开发界面，通过下图的新建按钮，可以按需创建同步任务、SQL 任务等任务类型：
-![](.topwrite/assets/image_1715856137643.png)
-
-^
-
-#### 任务调试运行
-
-任务创建后，可进行编码和配置。完成这些操作后，可使用“运行”功能测试代码逻辑是否正确。
-![](.topwrite/assets/image_1715856147701.png)
-
-^
-
-#### 任务调度配置和提交发布
-
-完成测试后，在“配置”选项中，可以设定任务的调度属性，包含定时调度的时间、调度的上游依赖等。配置完成后，通过点击“提交”按钮，将任务发布到生产环境进行定期调度运行。
-![](.topwrite/assets/image_1715856159293.png)
-
-### 配置监控告警以监控任务运行情况
-
-任务上线发布后，使用 **监控告警** 模块可配置监控规则，以监测任务运行失败等需要观测的状态或指标，并通过在告警中配置的通知渠道通知负责人进行处理。
-
-#### 监控规则配置
-
-以本次示例为例，配置监控任务实例的运行失败状态，给定具体的任务名称，并配置好通知渠道（基于通知策略）和通知人员等，如下图所示：
-![](.topwrite/assets/image_1715856178384.png)
-![](.topwrite/assets/image_1715856188374.png)
-
-在通知策略中，可配置推送间隔和次数，例如每 10 分钟发送一次，最多发送 6 次，以避免告警被遗漏。
-![](.topwrite/assets/image_1715856196213.png)
-
-### 使用数据质量监控数据产出的正确性
-
-除了监控任务调度运行状态外，为避免因上游数据变更或后续代码变更引入逻辑问题，也需要监控数据的正确性、合理性等，以确保业务方能够放心使用数据。这里会使用到 **数据质量** 模块的功能：
-
-#### 质量规则配置
-
-在 **数据质量** 模块，可以配置数据质量的监控规则，以监控任务产出表中的数据。
-![](.topwrite/assets/image_1715856220634.png)
-以 dws\_tripdata\_summary 表中的 avg\_passenger\_count（平均乘客数） 字段为例，监控其最大值要大于1（即平均至少有1个乘客），可以按照如下方式配置。
-![](.topwrite/assets/image_1715856226837.png)
-
-^
-
-#### 质量规则运行
-
-质量规则支持多种触发方式，例如手动触发、定时触发和周期任务触发。手动触发可用于测试规则配置的正确性。在本实例中，将质量规则配置为“周期任务触发”，即通过表的产出任务来触发，以达到在任务运行完成后即刻触发质量校验的目的，并配置为使用“强阻塞调度”模式。此方式意味着如果质量规则校验失败，则会将关联的调度任务实例状态也置为失败，从而阻塞下游任务实例的调度运行，防止数据问题扩散。
-![](.topwrite/assets/image_1715856234080.png)
-
-### 生产问题的运维处置
-
-1. 在任务调度运行后，通过监控检测到任务实例运行失败，收到 IM 告警
-   ![](.topwrite/assets/image_1715856242741.png =446)
-2. 基于监控告警的内容，可以直达告警对象
-   ![](.topwrite/assets/image_1715856478879.png)
-3. 排查任务实例失败的原因，从任务的变更记录中查找发现存在代码变动
-   ![](.topwrite/assets/image_1715856492223.png)
-4. 在运维中，点击“编辑”按钮，前往查看任务详情。在任务的版本中，可以查看到任务的提交历史记录。
-   ![](.topwrite/assets/image_1715856513403.png)
-5. 通过版本的对比功能查看具体的变动。定位到是代码逻辑改动引入的问题，进行代码回滚操作来修复，并重新提交。
-   ![](.topwrite/assets/image_1715856521466.png)
-6. 任务重新提交后，在实例的详情页进行运维处置，重跑任务实例，**注意选择使用最新的代码和配置**。
-   ![](.topwrite/assets/image_1715856529104.png)
-7. 实例重跑成功后，系统**会自动触发数据质量规则的重新运行**，校验通过。
-   ![](.topwrite/assets/image_1715856539792.png)
-8. 查看任务状态监控，实例状态通过重跑恢复成功后，**告警会自动关闭、不再推送，完全无需人工操作处置**。
-   ![](.topwrite/assets/image_1715856549114.png)
-
-## 小结
-
-通过 Lakehouse Studio 产品内置的数据开发、任务调度、任务运维、数据质量和监控告警功能的配合使用，在任务运行失败时，能第一时间告警通知责任人进行处置；通过操作审计定位变动、利用版本管理进行变更回滚、基于回滚后的代码重跑任务实例等，可快速进行处置；同时，监控告警事件与任务实例状态联动，重跑任务实例成功后，会自动关闭告警，无需手动操作，减少了告警处置环节，可大幅节约问题排查处置和数据生产恢复的时间。
-
-这些功能完整覆盖了 DataOps 中数据开发管理和数据运维两个关键环节的需求，能为“可测试、可监控、可回滚”的数据安全稳定生产提供坚实的落地保障。

-# 数据分享
-
-## 什么是数据分享
-
-数据分享是云器Lakehouse提供的无复制数据共享功能，用于同服务区域下跨账户或跨服务实例的数据授权使用。在云器Lakehouse中，用户可通过share对象，向同服务区域内的其他账户分享指定table或view的数据，而不需要实际将数据复制给其他账户。
-
-基于数据分享功能，账户间可便捷、安全地分享数据并与自身的数据进行关联计算，充分挖掘数据价值。
-
-通过share对象分享的数据通过权限管控的方式保障数据安全，数据提供方可随时通过对share的权限管控取消指定数据的分享。
-
-数据消费方无需对被分享的数据所占存储资源付费，但需要使用自身的计算资源处理被分享数据。当被分享数据发生变化时，数据消费方可以立即获得最新数据，无需进行数据同步。
-
-:-: ![](.topwrite/assets/image_1704779759719.png =752)
-
-## 典型应用场景
-
-A企业需要将自身数据提供给其客户B企业使用，需要能做到数据实时更新且避免建立高成本的数据实时同步链路。此时A企业可创建share对象，将需要提供的数据授权至share对象，并将share指定给B企业在云器Lakehouse的服务实例。B企业即可立即使用A企业共享的数据。
-
-## 注意事项
-
-* 分享的数据均为“只读”，不允许消费方对数据进行修改、删除等操作。
-* 创建share对象的工作空间决定了该share对象所能添加的数据对象范围。不支持跨工作空间添加数据对象。
-* 一个share对象中最多分享1000个table或view对象。
-* 如需对一个table中的部分数据进行分享，建议根据分享数据的需要，创建对应的view视图，然后将view视图进行分享。
-* 分享的数据禁止数据消费方进行二次分享，以保护数据提供方的权益。
-* 目前不能阻止数据消费方对分享数据的复制行为，因此需要数据提供方谨慎选择分享数据的范围。
-
-## 数据分享的DDL命令
-
-[CREATE SHARE](create-share.md)
-
-[ALTER SHARE](alter-share.md)
-
-[GRANT TO SHARE](grant-to-share.md)
-
-[REVOKE FROM SHARE](revoke-from-share.md)
-
-[SHOW SHARES](show-shares.md)
-
-[DESC SHARE](desc-share.md)
-
-[DROP SHARE](drop-share.md)
-
-## 支持share的数据对象
-
-当前支持share的数据对象有：table和view对象。
-
-支持使用 all tables in schema \<schema\_name> 和 all views in schema \<schema\_name> 的方式，将指定schema下的所有table和view对象加入到共享对象share中。 该操作包含“未来”创建在指定schema中的所有table和view对象，请谨慎操作。
-
-## 提供数据分享的操作
-
-### Web端
-
-**1. 创建share对象**
-
-为保障数据安全，数据分享（share）对象必须由具备“实例管理员”（instance\_admin）角色的用户创建。点击左侧菜单的“数据管理”-“数据分享”，进入数据分享列表页。
-
-点击“+新增分享”，打开新建数据分享窗口：
-
-:-: ![](.topwrite/assets/image_1734492957409.png =507)
-
-1）填写数据分享的“分享名称”。
-
-2）选择“工作空间”，指将要分享的table或view所在的工作空间，一个数据分享（share）对象仅可包含一个工作空间下的数据。
-
-3）在数据对象行，点击“添加”。选择数据分享中需要包含的具table或view，可以选择多个。但请注意，不可选择来源于其他数据分享的表和视图，因为数据分享的授权中不允许对数据进行二次分享。使用web端创建的数据分享仅支持包含已存在的table和view，暂不支持指定整个schema下“未来”创建的table或view对象。
-
-4）在接收实例行，点击“添加”。输入需要接收数据的服务实例名称。服务实例名称在Lakehouse服务中全局唯一。服务消费端用户可在首页右侧或在服务实例的URL中找到自己的服务实例名称并提供给分享者进行配置。
-
-:-: ![](.topwrite/assets/share_img_instancename.png =786)
-
-^
-
-*注意*：
-
-1. *为保障以工作空间为隔离域的数据安全，仅具备工作空间管理员角色的用户可在数据分享（share）中添加其管理的工作空间内的数据对象*。
-2. *创建数据分享（share）对象弹窗中的“创建”和“添加数据”是两个操作，即使添加要分享的数据全部失败或部分失败，并不会影响分享对象的创建。任意操作出现失败时，会返回报错信息。你可以在数据分享列表中点击已创建的数据分享，继续添加数据对象或要接收数据的服务实例*。
-
-**2. 查询已创建数据分享（share）对象**
-
-所有当前服务实例内已创建的数据分享（share）对象，均在“数据分享”列表页显示。具备服务实例管理员角色（instance\_admin)或工作空间管理员角色（workspace\_admin)的用户，可以查看数据分享（share）对象列表。
-
-:-: ![](.topwrite/assets/image_1734493289109.png =737)
-
-**3. 查询数据分享（share）详情**
-
-在“数据分享”列表页显示点击具体的数据分享名称，即可查询该数据分享的详细信息，包括基础信息、接收分享的服务实例以及分享的数据对象。具备服务实例管理员角色（instance\_admin)或工作空间管理员角色（workspace\_admin)的用户，可以查看数据分享（share）对象的详情。
-
-:-: ![](.topwrite/assets/image_1734493331354.png =735)
-
-**4. 添加/删除分享的数据对象**
-
-数据分享所属空间的空间管理员角色用户，可以添加或删除该数据分享中的数据对象（table或view）。
-
-在数据分享列表页，点击要添加数据对象的share对象名称，进入share对象详情页面。点击“编辑”按钮，在弹窗中选择要添加或删除的数据对象。点击“确定”完成分享数据对象的更新。不可添加来源于其他share对象的数据。
-
-添加后的数据对象会立即被share对象的消费者可见，出现在其提取数据的schema中。

-需要对share对象配置被分享的服务实例名称（instance\_name）才可完成数据分享。服务实例名称需要数据消费端提供。
-
-:-: ![](.topwrite/assets/image_1734493417202.png =771)
-
-^
-
-**6. 删除share对象**
-
-具备服务实例管理员角色（instance\_admin)角色的用户，或该数据分享所属空间的工作空间管理员角色（workspace\_admin)的用户，可以删除数据分享对象。
-
-在数据分享列表页或数据分享详情中，点击“操作”中的“删除”按钮，即可完成数据分享对象的删除。share对象一经删除不可恢复。数据消费端会立即失去对被分享数据的使用权限。
-
-### 使用SQL操作
-
-**1. 创建share对象**
-
-为保障数据安全，share对象必须由具备“实例管理员”（instance\_admin）角色的用户创建。创建share对象时，需要在计划分享数据的工作空间中执行以下语句：
-
-```SQL
-CREATE SHARE <share_name>;
-```
-
-***
-
-**2. 向share对象添加要分享的数据对象**
-
-创建出的share对象初始不包含任何数据对象，需要通过 Grant 语句添加需要分享的数据对象，语法为：
-
-```SQL
-GRANT select, read metadata ON {TABLE <table_name> | VIEW <view_name>} TO SHARE <share_name>;
-```
-
-例如：
-
-```SQL
-GRANT select, read metadata ON TABLE share_demo_table TO SHARE share_demo;
-```
-
-可以使用all tables in schema 或 all views in schema方式将指定schema下当前和未来所有table或view对象添加至share中，例如：
-
-```SQL
-Grant select, read metadata on ALL tables in SCHEMA share_demo_schema TO SHARE share_demo;
-Grant select, read metadata on ALL views in SCHEMA share_demo_schema TO SHARE share_demo;
-```
-
-向share对象添加要分享的数据对象时，执行操作的用户必须具备分享涉及table或view对象的select （查询）和 read metadata （查看元数据）权限，并可以进行二次授权 （with grant option）。工作空间管理员角色（workspace\_admin）天然具备上述权限。
-
-需要取消share对象中分享的数据对象时，可通过revoke语句实现：
-
-```SQL
-REVOKE select, read metadata on {TABLE <name> | VIEW <name>} FROM SHARE <share_name>;
-```
-
-注意：当分享table或view对象时，由于table或view对象一定存在于一个schema对象下，所以该schema的元数据权限（read metadata）也会被自动添加至该share对象中。当取消share中的table或view对象时，其所属schema的元数据权限也会被自动移除。
-
-***
-
-**3. 配置share的分享目标**
-
-需要对share对象配置被分享的服务实例名称（instance\_name）才可完成数据分享。服务实例名称需要数据消费端提供。
-
-服务实例名称在Lakehouse服务中全局唯一。服务消费端用户可在首页右侧或在服务实例的URL中找到自己的服务实例名称并提供给分享者进行配置。
-
-:-: ![](.topwrite/assets/share_img_instancename.png =786)
-
-数据分享者配置share分享目标的语法如下:
-
-```SQL
-ALTER SHARE <share_name> [ADD | REMOVE] INSTANCE <instance_name>; 
-```
-
-其中ADD为添加，REMOVE为移出。该操作即时生效，可随时对share添加或移出分享目标实例。一个share对象可以分享给多个服务实例。
-
-完成上述三步操作后，即完成了数据向指定服务实例的分享。
-
-^
-
-**4. 查询已创建share对象**
-
-可以通过执行show命令查询已创建的share对象，语法如下：
-
-```SQL
-SHOW SHARES;
-```
-
-返回结果示例如下：
-
-:-: ![](.topwrite/assets/share_img_showshares.png =803)
-
-其中：
-
-* provider为share提供者的租户名；
-* provider\_instance为share提供者的服务实例名；
-* provider\_workspace为share所属的工作空间；
-* scope为share的分享范围，当前仅支持PRIVATE——指定instance分享；
-* to\_instance为该share对象指定被分享至的服务实例名称，多个服务实例名称之间用英文逗号(,)分隔；
-* kind为share的类型，OUTBOUND为当前服务实例分享出的数据，INBOUND为其他服务实例分享至当前服务服务实例的数据。
-
-^
-
-**5. 查询指定share分享的数据对象**
-
-可以执行以下语句查询share中已被授予的数据对象：
-
-```SQL
-DESC SHARE <share_name>;
-```
-
-返回结果示例如下：
-
-:-: ![](.topwrite/assets/share_img_descshare.png =798)
-
-^
-
-**6. 删除share对象**
-
-可执行以下命令删除当前服务实例创建的share对象：
-
-```SQL
-DROP SHARE <share_name>;
-```
-
-share对象一经删除不可恢复。数据消费端会立即失去对被分享数据的使用权限。
-
-## 使用被分享数据的操作
-
-### Web端
-
-**1.查询被分享数据**
-
-使用具备服务实例管理员（instance\_admin）角色或工作空间管理员（workspace\_admin）角色的用户，在“数据分享”菜单的“分享给我”页签中，能够查看到所有分享给当前服务实例的数据分享对象。
-
-点击数据分享对象名称，可以查看该数据分享的来源、接收时间以及该数据分享中当前所包含的数据（table或view）。
-
-:-: ![](.topwrite/assets/image_1734493496334.png =777)
-
-^
-
-**2.提取被分享share创建schema**
-
-在“分享给我”的列表页，或数据分享对象的详情页面，点击“提取”按钮，即可提取该分享中的数据。
-
-:-: ![](.topwrite/assets/image_1734493713534.png =793)
-
-提取数据时，只能以schema为单位提取，暂不支持单独提取table或view。
-
-:-: ![](.topwrite/assets/image_1734493642759.png =541)
-
-首先需要选择“源schema”，即需要提取该分享中哪些schema的数据。如果数据分享中包含多个schema，需要操作多次提取。
-
-然后选择数据提取目标的工作空间，并输入存放数据的schema名称。数据提取操作将在该工作空间中新建一个schema，并存放源schema中的数据。注意，该schema被创建后为“只读”schema，不可在此schema中新建其他数据对象。
-
-完成上述选择和输入后，点击“确定”即可完成数据提取。
-
-**3. 使用被分享数据**
-
-完成数据提取操作后，即可在指定创建的schema下看到share对象中该schema下分享的所有table和view对象。并可以对这些table、view对象执行select查询或与其他table、view进行join查询。
-
-被分享数据在“数据”栏中以特殊图标标识，以便区分。
-
-:-: ![](.topwrite/assets/image_1734493884869.png =279)
-
-### 使用SQL操作
-
-**1. 查询被分享数据**
-
-数据消费方可通过show shares命令查询被分享的share对象。使用方式和返回结果与提供数据分享的第3步一致。
-
-进一步，可通过desc shares命令，查询被分享的share中包含哪些schema和table对象。
-
-^
-
-**2. 使用被分享share创建schema**
-
-通过share分享的数据，需要在消费端创建对应的schema才可查询和使用。操作语句如下：
-
-```SQL
-CREATE SCHEMA <schema_name> FROM SHARE <provider_instance>.<share_name>.<schema_name>;
-```
-
-其中\<provider\_instance>和\<share\_name>可通过show shares命令的查询结果获得；\<schema\_name>可通过desc share \<share\_name>命令指定share名称查询获得。
-
-Create schema \<schema\_name>中的schema名称可以自行定义，不必与share中的schema名称相同。
-
-执行上述命令时，操作者必须具备在执行操作的工作空间创建schema的权限。工作空间管理员角色（workspace\_admin）默认具备上述权限。
-
-^
-
-**3. 使用被分享数据**
-
-完成create schema from share 的执行后，即可在指定创建的schema下看到share对象中该schema下分享的所有table和view对象。并可以对这些table、view对象执行select查询或与其他table、view进行join查询。
-
-## share对象的权限
-
-**1. 提供者权限**
-
-仅服务实例管理员（instance\_admin）角色的用户可以创建数据共享（share）对象。执行创建
-
-share对象的权限点如下，暂不支持使用grant 语句将share对象的权限授予其他角色或用户。
-
-| **权限点**                                                         | **说明**                                                                        |

-| Drop share                                                      | 删除share实例。                                                                    |
-| Read metadata                                                   | show shares和 desc share权限。其中desc share可返回share 中包含的object和授予的objectPrivilege。 |
-| Grant objectprivilege to shareRevoke objectprivilege from share | 为share添加或移出数据对象：Grant objectPrivilege to;Revoke objectPrivilege from。         |
-
-^
-
-**2. 消费者权限**
-
-工作空间中成员均具备share对象的use和read metadata权限。但必须具备在工作空间中的create schema权限才可以使用share中分享的数据创建出schema。
-
-| **权限点**       | **说明**                                        |

-# 数据源IP白名单配置指南
-
-## 应用场景
-
-当数据源部署在内网环境或具有严格的安全管控要求时，需在**源端数据库/服务器**配置 IP 白名单：
-
-1. 仅允许数据同步服务IP段访问源数据
-2. 防止未经授权的网络访问
-3. 满足企业网络安全审计要求
-
-## 前置准备
-
-* 确认目标数据源支持IP白名单机制
-* 获取数据同步服务所在服务器的公网IP地址
-* 确保具备数据源管理权限
-
-## 配置流程
-
-如果在配置数据源、测试连通性或者同步任务运行时，遇到因白名单限制导致的报错，可以按照此文档进行操作。
-
-### 步骤1：获取数据同步服务出口IP地址
-
-根据实际使用服务所在的云和地域，获取对应的IP地址：
-
-| 服务地域 | IP 地址 |
-| :--- | :--- |
-| 阿里云·上海 | 47.100.176.72 |
-| 阿里云·新加坡 | 47.237.31.114 |
-| 腾讯云·上海 | 110.40.220.6, 124.220.91.8, 101.34.216.184 |
-| 腾讯云·北京 | 101.42.151.242, 101.42.224.202, 43.138.11.31 |

-| 亚马逊云·新加坡 | 54.251.190.22, 13.250.195.227 |
-
-### 步骤2：源端数据库白名单配置
-
-1. **登录源数据库管理控制台**
-   * MySQL：通过安全组或数据库参数设置
-   * Oracle：通过 `SQLNET.ORA` 文件配置
-   * SQL Server：通过服务器防火墙设置
-
-2. **添加IP白名单规则**
-   以阿里云 RDS MySQL 版为例，以下是基于**阿里云控制台**界面的详细操作步骤：
-
-   **步骤 1：登录阿里云控制台**
-   打开浏览器，访问阿里云官网，使用您的阿里云账号登录。
-
-   **步骤 2：进入 RDS 管理控制台**
-   登录后，点击顶部菜单中的“**产品与服务**”，然后选择“**数据库**” > “**关系型数据库 RDS**”。
-
-   **步骤 3：选择目标 RDS 实例**
-   在 RDS 控制台页面，找到你想要操作的 RDS 实例。点击实例名称，进入实例详情页面。
-
-   **步骤 4：进入“白名单设置”**
-   在实例详情页面，找到左侧菜单中的“**安全设置**”。点击“**白名单设置**”选项。
-
-   **步骤 5：添加白名单**
-   在“白名单设置”页面，您会看到当前的白名单配置。点击“**添加白名单分组**”按钮，或在已有的白名单分组中直接添加 IP 地址。
-
-   **步骤 6：配置白名单**
-   在弹出的对话框中，输入白名单分组名称（可选）。在“**白名单内容**”框中，输入允许访问的 IP 地址或 IP 段。可以输入多个 IP 地址或 IP 段，用英文逗号分隔，例如：`47.100.176.72`。然后点击“**确定**”完成添加。
-
-   **步骤 7：保存白名单设置**
-   添加完成后，点击页面底部的“**保存**”按钮，保存白名单设置。
-
-### 步骤3：数据同步验证
-
-1. 在数据源配置中，点击“测试连通性”。如果成功，通常表明配置已生效。
-2. 为保险起见，可以创建测试同步任务并手动执行。
-3. 观察任务日志是否显示连接成功。
-4. 失败时检查同步任务日志和数据库审计日志。
-
-## 注意事项
-
-具体配置方式可能因数据源类型（MySQL/Oracle等）而异，请参考对应数据源的官方文档。如需访问云产品，请前往各云产品帮助中心查看其添加白名单的注意事项。白名单设置通常会立即生效，但也可能需要几分钟。
-
-## 常见问题
-
-### Q1：已添加 IP 白名单仍无法连接
-
-* 检查 IP 地址是否准确（建议通过 `curl ifconfig.me` 验证出口 IP）
-* 确认数据源防火墙已开放对应端口
-* 检查白名单配置是否已生效（部分数据库需重启生效）
-
-### Q2：白名单维护最佳实践
-
-1. 为数据同步服务单独创建访问账号。
-2. 按最小权限原则配置访问范围。
-3. 定期审计白名单中的IP地址。
-4. 建议配合VPN/专线提升安全性。
-5. 不要将 `0.0.0.0/0`（允许所有 IP 访问）添加到生产环境的白名单中，除非绝对必要。

-# 数据类型转换
-
-在 SQL 语句中，数据类型转换是一项常见的操作。本文将介绍如何在 SQL 中进行数据类型转换，以及相关的函数和语法。
-
-## 数据类型转换函数
-
-### CAST 函数
-
-CAST 函数用于将一个数据类型的值转换为另一个数据类型的值。如果转换过程中超出目标数据类型的范围，则会引发溢出异常。
-
-#### 语法
-
-```
-CAST(expression AS type)
-```
-
-参数说明：
-
-* expression：必填。待转换的数据源。
-* type：必填。目标数据类型。用法如下：
-  * `CAST(double AS bigint)`：将 DOUBLE 数据类型值转换为 BIGINT 数据类型。
-  * `CAST(string AS bigint)`：将字符串转换为 BIGINT 数据类型。如果字符串中是整型表达的数字，则直接转换为 BIGINT 类型。如果字符串中是浮点数或指数形式表达的数字，则先转换为 DOUBLE 数据类型，再转换为 BIGINT 数据类型。
-  * `CAST(string AS timestamp)` 或 `CAST(timestamp AS string)`：会采用默认的日期格式 `yyyy-MM-dd HH:mm:ss`。
-
-#### 示例
-
-```sql
-SELECT CAST(rand() AS INT);
--- 执行结果 0
-```
-
-### TYPE(expr)
-
- 函数用于将一个值从一种数据类型转换为另一种数据类型。如果转换成功，返回转换后的值；如果转换失败，默认返回 NULL。
-
-#### 语法
-
-```
-TYPE(expr)
-```
-
-参数说明：
-
-* TYPE类型：支持float\double\tinyint\smallint\int\bigint\string\date\timestamp\timestamp\_ntz\binary\boolean
-* expr：必填。要转换的表达式。
-
-#### 示例
-
-```sql
-SELECT binary('1');
--- 执行结果 [31]
-```
-
-```sql
-SELECT INT(100.6);
--- 执行结果 100
-```
-

-# 数据类型转换
-
-数据类型转换是指将一种数据类型的值转换为另一种数据类型的值的过程。数据类型转换可以分为隐式转换和显式转换。隐式转换是指在执行某些操作时，系统自动进行的数据类型转换，例如算术运算、比较运算、函数调用等。显式转换是指用户使用特定的函数或语法来指定数据类型转换，例如CAST等。不同的数据库系统可能有不同的数据类型转换规则和函数。本文将介绍lakehouse的数据类型转换特点和用法
-
-# 显式转换
-
-Lakehouse支持两种方式进行显式类型转换：使用 `CAST` 函数或使用 `::` 符号。这两种方式是等价的，例如 `CAST(a AS INT)` 等价于 `a::INT`。`::` 符号提供了更简洁的语法来执行类型转换。
-
-下图显示使用cast转换的行为，

-黑色加粗代表可能会报错或者转换为null，需要说明lakehouse为了避免用户写SQL转换值失败，采用了转换更宽松的行为，黑色加粗部分引发异常会转换为null，当然你也可以设置标准行为黑色加粗部分为严格模式也可以报错,开启严格模式set cz.sql.cast.mode=strict;开启后你可以直接使用[try\_cast](datatype-cast.md)函数报错行为将返回null，详情可以参考参数管理
-
-* CAST(Numeric AS Numeric)：如果超出目标数据类型的范围，lakehouse默认会转换为null
-* 将 FLOAT 转换为 INTEGER 对值进行截断
-* 将 TIMESTAMP 转换为 DATE 会删除有关一天中时间的信息
-
-# 隐式转换
-
-当两个不同类型的值进行算术运算或比较运算时，Lakehouse SQL会按照一定的优先级进行隐式转换，以保证运算结果的精度和范围。优先级的顺序如下图。也就是说，如果两个值的类型不同，那么类型较低的值会被转换为类型较高的值，以匹配另一个值的类型。例如，当整数和小数进行加法运算时，整数会被转换为小数，以避免精度损失。当日期和时间戳进行比较运算时，日期会被转换为时间戳，以保证时间粒度的一致性。

-
-图中类型由低到高排布最上层为最低类型
-
-**特别注意**
-
-lakehouse为了避免用户写SQL转换值失败，隐式转换和显式转化采用了转换更宽松的行为，引发异常会转换为null。你可以开启严格模式set cz.sql.cast.mode=strict;详情可以参考参数管理
-比如
-
-```
---18.234超过了指定的转化范围，使用cast转化如果没有开启严格模式结果为null
-SELECT cast(18.234 AS decimal(4, 3)) AS res;
-+------+
-| res  |
-+------+
-| null |
-+------+
---开启严格模式，则会报错精度异常
-set cz.sql.cast.mode=strict;
-SELECT cast(18.234 AS decimal(4, 3)) AS res;
-CZLH-22003:[1,8] cannot cast `18.234` to decimal32 due to an overflow. Use `try_cast` to tolerate overflow. Detail  taskId 0

-```
-
-# 案例
-
-隐示转换
-
-```SQL
---decimal和double运算
-SELECT typeof(10bd +3.14D) ;
-+----------------------+
-| typeof(10BD + 3.14D) |
-+----------------------+
-| double               |
-+----------------------+
-```
-
-显示转换
-
-```SQL
-SELECT CAST(‘123’ AS INT)

-### 日期时间格式
-
-#### 概述
-
-在处理和展示日期时间信息时，正确地格式化和解析这些信息至关重要。CZ 提供了一系列日期时间格式符号，以便用户根据不同的需求来格式化、表示和处理日期时间数据。
-
-#### 日期时间格式符号
-
-| 符号 | 描述 | 支持类型 | 示例 |
-|:----:|:----:|:-------:|:----:|
-| y   | 年份 | 4位数字 | 2022  |
-| M   | 月份 | 1位或2位数字 | 3; 03  |
-| d   | 日期 | 1位或2位数字 | 5; 05  |
-| H   | 小时（24小时制） | 1位或2位数字 | 10; 23 |
-| m   | 分钟 | 1位或2位数字 | 5; 59  |
-| s   | 秒 | 1位或2位数字 | 8; 59  |
-| S   | 毫秒/微秒 | 1至6位数字 | 324123; 123456 |
-| '   | 字符常量 | 文本 | 'yyyy' |
-
-#### 详细说明
-
-1. 年份 (y)
-   - `yyyy`：表示四位数的年份，例如 2022。
-
-2. 月份 (M)
-   - `M`：表示不带前导零的月份。
-   - `MM`：表示带前导零的月份，例如 03 或 12。
-
-3. 日期 (d)
-   - `d`：表示不带前导零的日期。
-   - `dd`：表示带前导零的日期，例如 05 或 20。
-
-4. 小时（24小时制，H）
-   - `H`：表示不带前导零的小时。
-   - `HH`：表示带前导零的小时，例如 01 或 23。
-
-5. 分钟 (m)
-   - `m`：表示不带前导零的分钟。
-   - `mm`：表示带前导零的分钟，例如 04 或 59。
-
-6. 秒 (s)
-   - `s`：表示不带前导零的秒。
-   - `ss`：表示带前导零的秒，例如 08 或 59。
-
-7. 毫秒/微秒 (S)
-   - `S`：表示毫秒和微秒，可以是1至6位数字。从左到右依次为毫秒（3位）、微秒（3位）。纳秒（3位）在 CZ 中会被忽略。如果 S 的位数不足 6 位，则从右边开始降低精度。CZ 目前只支持微秒级别的时间戳精度。
-
-8. 字符常量 (')
-   - `'`：用于插入文本字符，例如 `'你好世界'`。
-
-#### 示例
-
-以下是一些使用不同日期时间格式的示例：
-
-1. `yyyy-MM-dd HH:mm:ss.SSSS`：2022-01-10 10:05:02.123456
-2. `yyyy/MM/dd HH:mm:ss.SSSS`：2022/01/10 10:05:02.123456
-3. `yyyy年MM月dd日 HH时mm分ss秒SSS毫秒`：2022年01月10日 10时05分02秒123毫秒
-4. `'今天是y年MM月dd日 d天' HH:mm:ss.SSSS`：今天是2022年01月10日 5天 10:05:02.123456
-5. `yyyy'你好世界'yMdH'-MM-dd HH:mm:ss.SSSS`：2022你好世界yMdH-01-10 10:05:02.123456
-
-通过上述格式符号和示例，用户可以灵活地根据需要创建和解析日期时间字符串。请注意，在解析时间字符串时，系统会根据格式符号的要求来解析每个部分。如果输入的字符串与指定的格式不匹配，将无法正确解析日期时间信息。因此，请确保输入的字符串严格遵循所选的日期时间格式。

-    username=os.getenv('CLICKZETTA_USERNAME'),
-    password=os.getenv('CLICKZETTA_PASSWORD'),
-    instance=os.getenv('CLICKZETTA_INSTANCE'),
-    workspace=os.getenv('CLICKZETTA_WORKSPACE'),
-    schema=os.getenv('CLICKZETTA_SCHEMA'),
-    vcluster=os.getenv('CLICKZETTA_VCLUSTER')
-)
-
-# 测试连接
-namespaces = {'lakehouse': {'lakehouse': db_config}}
-db_manager = DBManager(namespaces)
-
-try:
-    connector = db_manager.get_conn('lakehouse', 'lakehouse')
-    result = connector.test_connection()
-    print('✅ 云器Lakehouse连接测试成功！')

-```bash
-# 启动交互式CLI
-datus-cli --namespace lakehouse --config conf/agent.yml
-```
-
-### 方式二：Web模式（推荐，支持subagent选择）
-
-```bash
-# 启动Web界面，支持选择不同的subagent
-datus-cli --namespace lakehouse --config conf/agent.yml --web --host 0.0.0.0
-
-# 或者只在本地访问
-datus-cli --namespace lakehouse --config conf/agent.yml --web --host 127.0.0.1
-```
-
-**Web 模式启动后**：
-
-* 默认访问地址：<http://localhost:8501> 或 <http://0.0.0.0:8501>
-* 在Web界面中可以选择之前创建的subagent进行对话
-* 支持更直观的交互界面
-
-**启动成功后的界面**：
-
-**CLI 模式**：
-

-## 默认值
-
-### 语法
-
-```SQL
-CREATE TABLE [ IF NOT EXISTS ] table_name
-(
-    column_definition DEFAULT default_expression, [column_definition,...]
-)
-[ PARTITIONED BY (column_name column_type | column_name ) ];
-```
-
-* **DEFAULT default_expression**：为新添加的列定义一个默认值。如果在 INSERT、UPDATE 或 MERGE 操作中未指定该列的值，将自动使用此默认值。对于添加列之前已存在的数据行，该列将填充为 null。支持非确定性函数（如 `current_date`、`random`、`current_timestamp`、上下文函数）和常量值。
-
-### 生成列和默认值区别
-
-1. **分区列支持**：
-   * **默认值**：当前不支持为分区列设置默认值。
-   * **生成列**：支持为分区列生成值。
-
-2. **函数支持**：
-   * **默认值**：支持使用非确定性函数，如 `current_timestamp()`。
-   * **生成列**：不支持非确定性函数，只能使用确定性的标量函数。
-
-3. **插入操作中的值指定**：
-   * **默认值**：在插入数据时，可以为列指定一个静态值，如果未指定，则使用默认值。
-   * **生成列**：在插入数据时，不能为生成列指定值，其值完全由生成表达式决定。
-
-4. **列值来源**：
-   * **默认值**：不支持列的值来自其他列的转换。
-   * **生成列**：支持列的值来自其他列的转换，即可以基于其他列的值计算生成。
-
-5. **现有数据行的处理**：
-   * **默认值**：当为现有表添加带有默认值的列时，已存在的数据行中的该列将填充为 null。
-   * **生成列**：对于已存在的数据行，生成列的值将根据生成表达式进行计算，并显示计算结果。
-
-### 使用限制
-
-* 不支持分区列使用默认值。
-* 支持批量接口写入，包括Studio数据集成的批量导入。实时接口写入时默认值不会生效，因为调用实时接口时必须指定所有的列。
-* 不支持类似生成列中可以引用其他列的函数方式。
-
-### 插入数据
-
-```SQL
-CREATE TABLE t_default
-(
-    id   int,
-    col1 string DEFAULT current_timestamp (),
-    col2 string DEFAULT '1',
-    col3 int    DEFAULT 1,
-    clo4 json   DEFAULT '1',
-    col5 DOUBLE DEFAULT random(),
-    col6 date   DEFAULT current_date()
-);
-INSERT INTO t_default (id) VALUES (1);
-```
-
-## 添加字段时指定默认值
-
-### 语法
-
-```SQL
--- 添加列
-ALTER TABLE table_name ADD COLUMN
-      column1_name_identifier data_type [column_properties]
-      [FIRST | AFTER column1_name_identifier]  ,....
-
-column_properties:==
-    DEFAULT default_expression |
-    COMMENT column_comment 
-```
-
-* **DEFAULT default_expression**：为新添加的列定义一个默认值。如果在 INSERT、UPDATE 或 MERGE 操作中未指定该列的值，将自动使用此默认值。对于添加列之前已存在的数据行，该列将填充为 null。
-
-### 使用限制
-
-* 不支持为已有的列添加默认值。
-
-### 示例
-
-#### 添加列并指定默认值
-
-```SQL
-ALTER TABLE my_table ADD COLUMN
-    new_col INT DEFAULT 0 AFTER existing_col;
-```
-
-在这个例子中，`new_col` 将被添加到 `existing_col` 后面，并且所有现有数据行的 `new_col` 将被设置为默认值 null。

-## DELTA LAKE
-Delta Lake 是一个开源的大数据框架，用于提供数据湖上的可靠性和性能。它建立在 Apache Spark 和其他大数据处理引擎之上，为存储在数据湖中的数据提供了一种结构化存储层，使得数据湖可以像数据仓库一样易于使用。Lakehouse 提供了外部表的方式来访问该格式数据。
-
-
-## 创建DELTA格式外部表
-
-[创建外部表语法](<create-external-table.md>)
-
-### **示例**
-
-```SQL
---创建conneciton
-CREATE STORAGE CONNECTION if not exists oss_delta
-    TYPE oss
-    ENDPOINT = 'oss-cn-beijing.aliyuncs.com'
-    access_id = 'xxx'
-    access_key = 'xxxx'
-    comments = 'delta';
-
---创建外部表,使用上面的连接信息
-CREATE EXTERNAL TABLE IF NOT EXISTS sales_data
-(
-  order_id INT,
-  product_id STRING,
-  sale_amount DOUBLE
-)
-PARTITIONED BY (dt STRING)
-USING DELTA
-CONNECTION oss_delta
-LOCATION 'oss://my-bucket/data/sales'
-COMMENT 'External table for sales data stored in OSS';
-```
-
-## 删除外部表
-
-```SQL
-DROP TABLE [ IF EXISTS ] [schema_name.]<table_name>
-```
-
-**参数说明**
-
-* `IF EXISTS`：可选，如果指定的表不存在，系统不会报错。
-* `schema_name`：可选，指定 schema 的名称。如果未指定，默认使用当前用户的 schema。
-* `table_name`：要删除的表名称。
-
-**说明**
-
-* 删除外部表并不会删除数据，因为数据存储在外部系统中，删除操作只会删除表的映射信息。
-
-**示例**
-
-```SQL
---删除已经创建的外部表
-DROP TABLE sales_data;
---删除名为 sales_data 的表，如果表不存在，不报错：
-DROP TABLE IF EXISTS sales_data;
---删除名为 my_schema 下的 sales_data表
-DROP TABLE my_schema.my_table;
-```
-
-## 查看外部表详情
-
-```SQL
-DESC[RIBE] [TABLE] [EXTENDED] table_name;
-```
-
-**参数说明**
-
-* **DESC\[RIBE]**：DESC和DESCRIBE可以互换使用，都表示描述表结构的命令。
-* **TABLE**：可选参数，用于指定查看表结构的类型，如BASE TABLE或VIEW等。
-* **EXTENDED**：可选参数，加入此关键字后，可以展示更多扩展信息，如表的创建语句和Location信息等。
-* **table\_name**：指定需要查看结构的表名。
-
-## 修改外部表
-
-### 重命名表
-
-通过ALTER TABLE命令，您可以将现有的表重命名为新的表名。
-
-**语法**
-
-```SQL
-ALTER TABLE name RENAME TO new_table_name;
-```
-
-**示例**
-
-```SQL
-ALTER TABLE old_table_name RENAME TO new_table_name;
-```
-
-### 修改表注释
-
-通过ALTER TABLE命令，您可以为表添加或修改注释。
-
-**语法**
-
-```SQL
-ALTER TABLE tbname SET COMMENT '';
-```
-
-**示例**
-
-```SQL
-ALTER TABLE scores SET COMMENT '这是一个成绩表';
-```
-## **外部表计费**
-
-* **存储费用**： 外部表不产生存储费用，因为数据不存储在 Lakehouse 中。
-* **计算费用**： 使用外部表进行计算会消耗计算资源，因此会产生计算费用。
-
-## **外部表权限**
-
-外部表和内部表权限点相同。由于外部表无法执行 INSERT、UPDATE、TRUNCATE、DELETE、UNDROP 等操作，所以没有对应的操作权限点。
-
-* **创建权限**： 需要具有创建表（create table）的权限。
-* **删除权限**：需要具有删除（DROP）权限。
-* **读取权限**： 需要具有选择（select）权限。
-
-## **使用注意事项**
-
-* **连接配置**： 创建 connection 时，确保 endpoint 配置正确，以便 Lakehouse 能够成功连接。如果 Lakehouse 和对象存储位于同一云服务且在同一区域，通常使用内网地址即可实现网络互通。如果不在同一网络环境，建议使用对象存储的公网地址。
-## 具体案例
-
-### 连接阿里云Oss
-
-```SQL
---创建connection,用于连接对象存储
-CREATE STORAGE CONNECTION  oss_delta
-    TYPE oss
-    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com'
-    access_id = 'xxxxxx'
-    access_key = 'xxxxxx'
-    comments = 'delta'
-    ;
---使用上面的链接信息，创建外部表
-CREATE    EXTERNAL TABLE pepole_delta (id int, name string,dt string) 
-USING DELTA 
-CONNECTION oss_delta 
-PARTITIONED BY (dt ) 
-LOCATION 'oss://bucketmy/delta-format/uploaddelta/' 
-COMMENT 'edelta-external';
-```
-
-### 连接Google GCS
-
-Lakehouse 连接 Google Cloud Storage (GCS) 时，将使用服务账号密钥进行身份验证。请按照以下步骤操作：
-
-1. **获取服务账号密钥**：
-
-   - 登录 Google Cloud 控制台。
-   -  按照 *[Google Cloud 文档](https://cloud.google.com/docs/authentication/getting-started)* 的指导，创建并下载服务账号的 JSON 密钥文件。
-
-2. **配置 ****`private_key`**** 参数**：
-
-   - 打开下载的 JSON 密钥文件，将文件中的私钥内容完整复制。
-
-3. **注意**：
-
-   - 在配置 `private_key` 时，必须前面添加r,r代表区分大小写，殊字符和 unicode 字符都不会被转义。
-
-```SQL
---创建connection,用于连接对象存储
-CREATE STORAGE CONNECTION  oss_delta
-    TYPE gcs
-    private_key=r'{
-  "type": "service_account",
-  "project_id": "PROJECT_ID",
-  "private_key_id": "KEY_ID",
-  "private_key": "-----BEGIN PRIVATE KEY-----\nPRIVATE_KEY\n-----END PRIVATE KEY-----\n",
-  "client_email": "SERVICE_ACCOUNT_EMAIL",
-  "client_id": "CLIENT_ID",
-  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
-  "token_uri": "https://accounts.google.com/o/oauth2/token",
-  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
-  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/SERVICE_ACCOUNT_EMAIL"
-}';
---使用上面的链接信息，创建外部表
-CREATE    EXTERNAL TABLE pepole_delta (id int, name string,dt string) 
-USING DELTA 
-CONNECTION oss_delta 
-PARTITIONED BY (dt ) 
-LOCATION 'gs://bucketmy/delta-format/uploaddelta/' 
-COMMENT 'edelta-external';

-# 查看动态表结构
-
-## 功能描述
-
-通过使用 DESC 或 DESCRIBE 语句，用户可以查看 Lakehouse 数据库中指定动态表的详细结构信息。添加 EXTENDED 关键字可以查看动态表的调度周期和刷新属性。
-
-## 语法格式
-
-```
-DESC[RIBE] [TABLE] [EXTENDED] dynamic_table_name;
-```
-
-## 参数说明
-
-* **DESC[RIBE]**：DESC 和 DESCRIBE 可以互换使用，都表示描述表结构的命令。
-* **TABLE**：可选参数，用于指定查看表结构的类型，如BASE TABLE或VIEW等。
-* **EXTENDED**：可选参数。加入此关键字后，可以查看动态表的调度周期、刷新属性、调度状态、使用的基表和条数大小等。
-* **dynamic_table_name**：指定需要查看结构的表名。

-
-**Dify Provider 架构核心概念**
-
-Dify采用Provider架构模式来实现与外部服务的解耦集成，这是一种成熟的软件设计模式，类似于云计算中的"服务提供商"概念。在Dify架构中，Provider承担以下关键角色：
-
-**Provider 分类与职责**：
-
-- 🤖 **Model Providers**：提供 AI 模型服务（LLM、Embedding、TTS 等）
-  * 示例：OpenAI、Anthropic、Azure OpenAI、本地模型
-- 🔍 **Vector Database Providers**：提供向量存储和检索服务
-  * 示例：Qdrant、Milvus、Weaviate、ClickZetta（云器 Lakehouse）
-- 💾 **Storage Providers**：提供文件存储服务
-  * 示例：AWS S3、Azure Blob、阿里云 OSS、ClickZetta Volume（云器 Lakehouse Volume）
-- 🛠️ **Tool Providers**：提供功能工具集合
-  * 示例：搜索工具、API 调用工具、数据处理工具
-
-**Provider 架构优势**：
-
-- ✅ **标准化接口**：统一的集成方式，降低开发和维护成本
-- ✅ **插拔式设计**：可以自由切换不同 Provider 而无需修改核心代码
-- ✅ **扩展性强**：新 Provider 可以无侵入地集成到现有系统
-- ✅ **配置灵活**：通过环境变量和配置文件灵活管理 Provider 参数
-- ✅ **厂商中立**：避免 vendor lock-in，支持多云和混合云部署
-
-**云器 Lakehouse 作为 Provider 的独特定位**
-
-与传统单一功能的 Provider 不同，**云器 Lakehouse** 在 Dify 中扮演**多重 Provider 角色**：
-
-1\. **Vector Database Provider**: 提供HNSW向量索引、倒排索引、混合检索
-
-2\. **Storage Provider**: 提供Volume存储、多租户隔离、跨云兼容
-
-3\. **Compute Provider**: 提供弹性计算、SQL查询、数据处理能力
-
-这种"一个Provider，多重角色"的设计，正是湖仓一体架构的核心价值体现。
-

-
-**传统分离式 Provider 架构 vs. ClickZetta 统一 Provider 架构**：
-
-**现有方案的技术挑战**：
-
-:-: ![](.topwrite/assets/image_1756879734460.png =734)
-
-***
-
-**关键技术差异分析**：
-
-1\. **Provider集成复杂度**
-
-* 传统方案：需要配置Storage Provider（S3/OSS）+ Vector Provider（Qdrant/Milvus），维护双重数据映射
-* 云器Lakehouse方案：单一Provider同时提供Volume存储 + Vector索引，元数据自动同步
-
-2\. **一体化检索能力对比**
-
-**传统分离式方案**：
-
-```Python
-# 向量检索：Qdrant/Milvus
-vector_results = qdrant_client.search(vector=query_vector, limit=top_k)
-
-# 全文检索：需要Elasticsearch
-text_results = elasticsearch.search(query=text_query)
-
-# 混合检索：需要应用层融合
-combined_results = merge_and_rank(vector_results, text_results)
-```
-
-**云器 Lakehouse 湖仓一体方案**：
-
-```Python
-# 向量检索 - HNSW索引
-vector_results = client.execute("""
-    SELECT content, metadata, 
-           COSINE_DISTANCE(vector, CAST(? AS VECTOR(1536))) as score
-    FROM dataset_table 
-    ORDER BY score LIMIT ?
-""", [query_vector, top_k])
-
-# 全文检索 - 倒排索引 (中文分词)
-text_results = client.execute("""
-    SELECT content, metadata, SCORE(content) as score
-    FROM dataset_table 
-    WHERE MATCH_ALL(content, ?)
-    ORDER BY score DESC LIMIT ?
-""", [text_query, top_k])
-
-# SQL Like检索 - 降级备用
-like_results = client.execute("""
-    SELECT content, metadata, 0.5 as score
-    FROM dataset_table 
-    WHERE content LIKE ?
-    LIMIT ?
-""", [f"%{text_query}%", top_k])
-
-# 混合检索 - 单SQL统一处理

-AWS_ACCESS_KEY = '...'       # 需要改为 ALIYUN_OSS_ACCESS_KEY
-AWS_SECRET_KEY = '...'       # 需要改为 ALIYUN_OSS_SECRET_KEY
-VECTOR_STORE = 'qdrant'      # 向量Provider可能也需要调整
-
-# ClickZetta统一Provider方案：Volume抽象层屏蔽云存储差异
-STORAGE_TYPE = 'clickzetta-volume'  # 跨云不变

-# 探索和分析数据湖Volume上的JSON文件里的数据
-
-## 1. 数据湖与JSON数据简介
-
-### 1.1 什么是数据湖（Data Lake）
-
-数据湖是Lakehouse的重要组成部分，允许您以原始格式存储所有结构化和非结构化数据，无需事先定义模式。这充分体现了湖仓一体的优势，将Lakehouse的数据管理扩展到对非结构化数据的一体化管理，不再局限于数据仓库中的结构化数据管理。这种灵活性使其成为大数据分析的理想选择，因为您可以根据需要使用不同的分析方法和工具来处理数据。数据湖通常由以下部分组成：
-
-* **存储层**：如对象存储（S3、OSS、COS等）
-* **元数据管理**：用于组织和发现数据
-* **处理引擎**：用于分析和转换数据
-
-### 1.2 数据湖中的Volume
-
-在Lakehouse等现代数据平台中，**Volume** 是一种抽象，它表示外部存储系统中的一个特定位置（例如对象存储中的一个路径）。Volume允许数据平台无缝访问存储在外部系统中的数据，而无需实际复制或移动这些数据。
-
-Volume的主要特点：
-
-* 直接连接到外部存储系统
-* 允许就地查询，无需ETL
-* 支持多种文件格式（JSON、CSV、Parquet等）
-* 可以与表进行集成，提供SQL访问能力
-
-### 1.3 JSON数据格式
-
-JSON（JavaScript Object Notation）是一种轻量级的数据交换格式，具有以下特点：
-
-* **半结构化**：灵活的键值对结构
-* **嵌套能力**：支持复杂的层次结构和数组
-* **广泛支持**：几乎所有编程语言都提供JSON解析支持
-* **人类可读**：相比二进制格式更容易理解
-
-在大数据领域，JSON被广泛用于存储事件数据、API响应、日志文件等。其灵活性使其非常适合存储形状变化的数据。
-
-## 2. 案例研究：GitHub事件数据
-
-### 2.1 数据集概述
-
-GitHub事件数据是一个公开可用的数据集，记录了GitHub平台上所有公开活动的时间序列。在本案例中，我们分析了存储在`gh_archive` Volume中的GitHub事件数据。
-
-**数据源细节**：
-
-* **Volume名称**：`gh_archive`
-* **文件路径**：`2025-05-14-0.json.gz`（表示2025年5月14日00:00-01:00时段的事件）
-* **文件格式**：压缩的JSON文件（使用gzip压缩）
-* **数据量**：单个文件约85.6 MB（压缩后），包含近20万条事件记录
-
-**数据结构**：
-每条记录包含以下主要字段：
-
-* `id`：事件唯一标识符
-* `type`：事件类型（如PushEvent、PullRequestEvent等）
-* `actor`：执行操作的用户信息
-* `repo`：相关的代码仓库信息
-* `org`：相关的组织信息（若适用）
-* `payload`：事件的详细信息（因事件类型而异）
-* `created_at`：事件创建时间
-* `public`：事件是否公开
-
-## 3. 通过SQL进行数据湖探索分析
-
-### 3.1 直接查询JSON文件
-
-Lakehouse数据湖平台允许直接对存储在Volume上的文件执行SQL查询，无需事先加载到表中：
-
-```sql
--- 分析事件类型分布
-SELECT type, COUNT(*) as count 
-FROM VOLUME gh_archive
-USING json
-OPTIONS('compression'='gzip')
-FILES('2025-05-14-0.json.gz')
-GROUP BY type
-ORDER BY count DESC
-```
-
-查询结果：
-
-```
-type                         count
-----------------------------  ------
-PushEvent                     131341
-CreateEvent                   21700
-PullRequestEvent              12537
-IssueCommentEvent             7807
-WatchEvent                    7196
-DeleteEvent                   4832
-PullRequestReviewEvent        3571
-IssuesEvent                   3569
-PullRequestReviewCommentEvent 2362
-ForkEvent                     1537
-ReleaseEvent                  1261
-...
-```
-
-**特点**：
-
-* **零ETL**：无需预先提取、转换和加载数据
-* **灵活访问**：可直接访问嵌套字段
-* **即席查询**：支持即时数据探索
-
-### 3.2 处理嵌套和复杂JSON结构
-
-JSON数据常常包含嵌套对象和数组，SQL提供了直接访问这些复杂结构的能力：
-
-```sql
--- 分析 PushEvent 提交中的文件操作类型分布
-SELECT 
-  CASE 
-    WHEN LOWER(payload.commits[0].message) LIKE '%add%' THEN 'Add'
-    WHEN LOWER(payload.commits[0].message) LIKE '%fix%' THEN 'Fix'
-    WHEN LOWER(payload.commits[0].message) LIKE '%update%' THEN 'Update'
-    WHEN LOWER(payload.commits[0].message) LIKE '%remove%' OR LOWER(payload.commits[0].message) LIKE '%delete%' THEN 'Remove'
-    WHEN LOWER(payload.commits[0].message) LIKE '%refactor%' THEN 'Refactor'
-    WHEN LOWER(payload.commits[0].message) LIKE '%deploy%' THEN 'Deploy'
-    WHEN LOWER(payload.commits[0].message) LIKE '%test%' THEN 'Test'
-    WHEN LOWER(payload.commits[0].message) LIKE '%doc%' THEN 'Documentation'
-    ELSE 'Other'
-  END as commit_type,
-  COUNT(*) as count,
-  ROUND(COUNT(*) * 100.0 / SUM(COUNT(*)) OVER (), 2) as percentage
-FROM VOLUME gh_archive
-USING json
-OPTIONS('compression'='gzip')
-FILES('2025-05-14-0.json.gz')
-WHERE type = 'PushEvent' 
-  AND payload.commits IS NOT NULL 
-  AND SIZE(payload.commits) > 0
-GROUP BY commit_type
-ORDER BY count DESC
-```
-
-查询结果：
-
-```
-commit_type    count   percentage
-------------   ------  ----------
-Other          46901   35.75
-Update         42211   32.17
-Deploy         17513   13.35
-Add            11775   8.97
-Fix            5027    3.83
-Test           3389    2.58
-Remove         3174    2.42
-Documentation  637     0.49
-Refactor       575     0.44
-```
-
-**特点**：
-
-* **路径导航**：使用点表示法访问嵌套对象
-* **数组索引**：使用方括号访问数组元素
-* **数组函数**：使用`SIZE()`等函数处理数组
-* **条件分析**：使用CASE语句进行分类和模式识别
-
-### 3.3 使用JSON路径访问深层嵌套数据
-
-可以使用路径表达式深入访问JSON文档的多层嵌套结构：
-
-```sql
--- 分析PR事件中的分支信息
-SELECT 
-  payload.pull_request.base.ref as base_branch,
-  payload.pull_request.head.ref as head_branch,
-  COUNT(*) as count
-FROM VOLUME gh_archive
-USING json
-OPTIONS('compression'='gzip')
-FILES('2025-05-14-0.json.gz')
-WHERE type = 'PullRequestEvent'
-  AND payload.action = 'opened'
-  AND payload.pull_request.base.ref IS NOT NULL
-  AND payload.pull_request.head.ref IS NOT NULL
-GROUP BY base_branch, head_branch
-ORDER BY count DESC
-LIMIT 15
-```
-
-查询结果：
-
-```
-base_branch   head_branch                                               count
-------------  --------------------------------------------------------  -----
-main          main                                                      508
-master        master                                                    499

-main          dev                                                       63
-main          github-actions/upgrade-dev-deps-main                      35
-dev           dev                                                       27
-main          github-actions/upgrade-main                               26
-main          prBranch                                                  25
-develop       develop                                                   20
-main          test                                                      20
-...
-```
-
-### 3.4 复杂条件过滤和正则表达式
-
-使用正则表达式和复杂条件组合过滤JSON数据：
-
-```sql
--- 查找机器人账户创建的PR并分析目标仓库
-SELECT 
-  REGEXP_EXTRACT(actor.login, '(.*?)\\[bot\\]') as bot_name,
-  repo.name as target_repo,
-  COUNT(*) as pr_count
-FROM VOLUME gh_archive
-USING json
-OPTIONS('compression'='gzip')
-FILES('2025-05-14-0.json.gz')
-WHERE 
-  type = 'PullRequestEvent' 
-  AND payload.action = 'opened'
-  AND actor.login LIKE '%[bot]'
-GROUP BY bot_name, target_repo
-HAVING pr_count > 5
-ORDER BY pr_count DESC
-LIMIT 15
-```
-
-查询结果：
-
-```
-bot_name        target_repo                                       pr_count

-...
-```
-
-### 3.5 高级聚合和条件统计
-
-使用条件聚合同时分析多个指标：
-
-```sql
--- 分析仓库活跃度：计算每个仓库的不同类型事件数量
-SELECT
-  repo.name,
-  COUNT(DISTINCT actor.id) as unique_contributors,
-  SUM(CASE WHEN type = 'PushEvent' THEN 1 ELSE 0 END) as push_count,
-  SUM(CASE WHEN type = 'PullRequestEvent' THEN 1 ELSE 0 END) as pr_count,
-  SUM(CASE WHEN type = 'IssueEvent' THEN 1 ELSE 0 END) as issue_count,
-  SUM(CASE WHEN type = 'WatchEvent' THEN 1 ELSE 0 END) as watch_count,
-  SUM(CASE WHEN type = 'ForkEvent' THEN 1 ELSE 0 END) as fork_count,
-  COUNT(*) as total_events
-FROM VOLUME gh_archive
-USING json
-OPTIONS('compression'='gzip')
-FILES('2025-05-14-0.json.gz')
-GROUP BY repo.name
-HAVING total_events > 100
-ORDER BY total_events DESC
-LIMIT 10
-```
-
-查询结果：
-
-```
-repo.name                    unique_contributors  push_count  pr_count  issue_count  watch_count  fork_count  total_events
---------------------------   -------------------  ----------  --------  -----------  -----------  ----------  ------------

-...
-```
-
-### 3.6 窗口函数分析
-
-使用窗口函数进行更复杂的排名和分组分析：
-
-```sql
--- 窗口函数分析：计算每个组织内最活跃的用户
-SELECT
-  org_login,
-  username,
-  event_count,
-  rank_in_org
-FROM (
-  SELECT
-    org.login as org_login,
-    actor.login as username,
-    COUNT(*) as event_count,
-    RANK() OVER (PARTITION BY org.login ORDER BY COUNT(*) DESC) as rank_in_org
-  FROM VOLUME gh_archive
-  USING json
-  OPTIONS('compression'='gzip')
-  FILES('2025-05-14-0.json.gz')
-  WHERE org.login IS NOT NULL
-  GROUP BY org_login, username
-) t
-WHERE rank_in_org <= 3 AND org_login IN (
-  SELECT org.login
-  FROM VOLUME gh_archive
-  USING json
-  OPTIONS('compression'='gzip')
-  FILES('2025-05-14-0.json.gz')
-  WHERE org.login IS NOT NULL
-  GROUP BY org.login
-  ORDER BY COUNT(*) DESC
-  LIMIT 5
-)
-ORDER BY org_login, rank_in_org
-```
-
-查询结果：
-
-```
-org_login                  username                            event_count  rank_in_org

-```
-
-### 3.7 文本分析和时间处理
-
-使用字符串函数和时间函数分析JSON数据中的时间模式：
-
-```sql
--- 验证事件类型和每小时活动的关系
-SELECT 
-  SUBSTR(created_at, 12, 2) as hour_of_day,
-  type,
-  COUNT(*) as event_count
-FROM VOLUME gh_archive
-USING json
-OPTIONS('compression'='gzip')
-FILES('2025-05-14-0.json.gz')
-GROUP BY hour_of_day, type
-ORDER BY hour_of_day, event_count DESC
-```
-
-查询结果：
-
-```
-hour_of_day  type                         event_count
------------  ---------------------------  -----------
-00           PushEvent                    131341
-00           CreateEvent                  21700
-00           PullRequestEvent             12537
-00           IssueCommentEvent            7807
-00           WatchEvent                   7196
-...
-```
-
-### 3.8 分析PR合并模式
-
-分析Pull Request的合并趋势：
-
-```sql
--- 分析PR合并趋势：查看PR从创建到合并的情况
-SELECT 
-  SUBSTRING(payload.pull_request.merged_at, 1, 10) as merge_date,
-  COUNT(*) as merged_prs
-FROM VOLUME gh_archive
-USING json
-OPTIONS('compression'='gzip')
-FILES('2025-05-14-0.json.gz')
-WHERE 
-  type = 'PullRequestEvent' 
-  AND payload.action = 'closed' 
-  AND payload.pull_request.merged = true
-  AND payload.pull_request.merged_at IS NOT NULL
-GROUP BY merge_date
-ORDER BY merge_date
-```
-
-查询结果：
-
-```
-merge_date  merged_prs
-----------  ----------
-2025-05-13  3
-2025-05-14  4448
-```
-
-### 3.9 将文件数据加载到表中进行进一步分析
-
-对于需要重复分析的数据，创建表可以提高查询性能：
-
-```sql
-CREATE TABLE github_events AS
-SELECT 
-  id,
-  type,
-  actor.login as actor_name,
-  actor.id as actor_id,
-  repo.name as repo_name,
-  repo.id as repo_id,
-  org.login as org_name,
-  created_at,
-  public,
-  payload
-FROM VOLUME gh_archive
-USING json
-OPTIONS('compression'='gzip')
-FILES('2025-05-14-0.json.gz')
-```
-
-**优势**：
-* **提升性能**：表可以使用索引和缓存提高查询速度
-* **数据转换**：可在加载时应用转换和列重命名
-* **持久访问**：创建持久化视图，避免重复解析原始数据
-
-## 4. 数据湖分析的主要技术特点
-
-### 4.1 模式灵活性
-
-数据湖分析的一个核心优势是**模式灵活性**：
-
-* **模式即读取**：只有在查询时才需要定义数据结构
-* **部分字段访问**：可以只查询需要的字段，忽略其他字段
-* **进化适应**：随着数据结构的变化，查询可以轻松适应
-
-例如，在我们的GitHub事件分析中，我们可以只关注特定事件类型或特定字段，而无需处理整个数据结构。
-
-### 4.2 计算下推与过滤优化
-
-Lakehouse数据湖技术支持**计算下推**，将过滤和转换操作推送到数据源：
-
-```sql
--- 高效的过滤查询示例
-SELECT actor.login, COUNT(*) as event_count
-FROM VOLUME gh_archive
-USING json
-OPTIONS('compression'='gzip')
-FILES('2025-05-14-0.json.gz')
-WHERE type = 'PushEvent'
-GROUP BY actor.login
-ORDER BY event_count DESC
-LIMIT 10
-```
-
-### 4.3 统一数据访问与格式选择
-
-将SQL分析应用于同一Volume中的不同类型数据文件：
-
-```sql
--- 1. 查询JSON文件
-SELECT COUNT(*) FROM VOLUME gh_archive
-USING json
-OPTIONS('compression'='gzip')
-FILES('2025-05-14-0.json.gz');
-
--- 2. 如果Volume中有CSV文件也可以使用类似语法查询
--- SELECT * FROM VOLUME volume_name
--- USING csv
--- OPTIONS('header'='true')
--- FILES('data.csv');
-```
-
-### 4.4 分布式处理能力
-
-数据湖分析引擎通常基于分布式计算框架，可以处理大规模数据集：
-
-* **并行处理**：自动将查询分解为并行执行的任务
-* **内存管理**：优化内存使用，处理超过单机内存容量的数据
-* **容错机制**：处理节点故障和恢复
-
-在GitHub事件分析中，即使单个文件相对较小，但同样的查询可以扩展到分析TB级的历史事件数据。
-
-## 5. 数据分析过程与方法论
-
-通过GitHub事件数据的案例，我们可以总结出一套在数据湖中分析JSON数据的方法论：
-
-### 5.1 探索性数据分析流程
-
-1. **初步预览**：获取数据样本，了解整体结构
-   ```sql
-   SELECT * FROM VOLUME gh_archive
-   USING json
-   OPTIONS('compression'='gzip')
-   FILES('2025-05-14-0.json.gz')
-   LIMIT 10
-   ```
-
-2. **概览统计**：了解数据分布和主要维度
-   ```sql
-   SELECT type, COUNT(*) as count 
-   FROM VOLUME gh_archive
-   USING json
-   OPTIONS('compression'='gzip')
-   FILES('2025-05-14-0.json.gz')
-   GROUP BY type
-   ORDER BY count DESC
-   ```
-
-3. **深入分析**：针对特定领域进行细化分析
-   ```sql
-   SELECT 
-     actor.login as username, 
-     COUNT(*) as event_count
-   FROM VOLUME gh_archive
-   USING json
-   OPTIONS('compression'='gzip')
-   FILES('2025-05-14-0.json.gz')
-   GROUP BY username
-   ORDER BY event_count DESC
-   LIMIT 15
-   ```
-
-4. **关联分析**：连接多个维度进行交叉分析
-   ```sql
-   SELECT 
-     org.login as organization,
-     type,
-     COUNT(*) as event_count
-   FROM VOLUME gh_archive
-   USING json
-   OPTIONS('compression'='gzip')
-   FILES('2025-05-14-0.json.gz')
-   WHERE org.login IS NOT NULL
-   GROUP BY organization, type
-   ORDER BY organization, event_count DESC
-   LIMIT 20
-   ```
-
-### 5.2 数据洞察方法
-
-在GitHub事件分析中，我们发现了几个关键洞察：
-
-1. **活动分布**：了解不同类型事件的占比，发现Push事件占主导（66%）
-2. **自动化趋势**：通过用户活跃度分析，发现自动化机器人账户（如github-actions\[bot]）贡献了大量活动
-3. **组织生态**：识别最活跃的组织，了解GitHub生态系统的组成
-4. **开发行为**：通过分析提交信息，了解开发者的工作方式和关注点
-5. **分支使用模式**：main和master仍然是最常见的目标分支名称
-6. **机器人活动**：dependabot、renovate和github-actions是最活跃的自动化机器人
-
-这些洞察直接来自于SQL查询，展示了SQL作为数据分析工具的强大能力。
-
-## 6. 最佳实践与优化技巧
-
-### 6.1 JSON数据分析优化
-
-* **选择性字段读取**：只选择分析所需的字段
-  ```sql
-  -- 只读取必要字段而非全部字段
-  SELECT 
-    type, 
-    actor.login, 
-    repo.name
-  FROM VOLUME gh_archive
-  USING json
-  OPTIONS('compression'='gzip')
-  FILES('2025-05-14-0.json.gz')
-  LIMIT 10
-  ```
-
-* **谓词下推**：尽早在查询中应用过滤条件
-
-* **谓词下推**：过滤条件（\`WHERE type = 'PushEvent'\`）被下推到存储层，利用列式统计信息（如最大值/最小值/布隆过滤器）跳过明显不匹配的数据块。
-* **列裁剪**：仅读取相关列（\`actor.login\`和\`type\`），跳过无关字段的解析。
-* **过滤优化**：存储层按块加载数据后，在内存中进一步过滤掉不匹配记录，最终仅保留有效数据参与计算。
-
-  ```sql
-  -- 提前过滤数据减少处理量
-  SELECT COUNT(*) 
-  FROM VOLUME gh_archive
-  USING json
-  OPTIONS('compression'='gzip')
-  FILES('2025-05-14-0.json.gz')
-  WHERE type = 'PushEvent'
-  ```
-
-* **正确处理NULL值**：使用`IS NULL`和`IS NOT NULL`检查缺失字段
-  ```sql
-  -- 识别并处理缺失数据
-  SELECT 
-    type,
-    COUNT(*) as total_count,
-    SUM(CASE WHEN org.login IS NULL THEN 1 ELSE 0 END) as without_org,
-    SUM(CASE WHEN org.login IS NOT NULL THEN 1 ELSE 0 END) as with_org
-  FROM VOLUME gh_archive
-  USING json
-  OPTIONS('compression'='gzip')
-  FILES('2025-05-14-0.json.gz')
-  GROUP BY type
-  ORDER BY total_count DESC
-  ```
-
-### 6.2 数据湖查询最佳实践
-
-1. **避免全表扫描**：尽可能使用过滤条件
-2. **合理使用聚合**：在数据量大时，优先考虑分布式聚合
-3. **选择性投影**：只选择必要的列，减少IO和内存占用
-4. **适当数据转换**：对频繁查询的数据，考虑转换为更高效的格式
-5. **利用数据分区**：基于文件名或路径进行逻辑分区
-6. **注意错误处理**：处理JSON解析错误和类型转换问题
-
-## 7. 总结
-
-通过SQL方式进行数据湖探索和分析的主要特点：
-
-1. **无需ETL**：直接查询原始数据，减少数据准备时间
-2. **灵活性**：适应半结构化数据，无需预定义模式
-3. **易用性**：使用熟悉的SQL语法，降低学习曲线
-4. **可扩展性**：处理从GB到PB级别的数据
-5. **统一访问**：同一接口处理多种数据格式
-6. **探索友好**：支持迭代式数据探索流程
-7. **性能优化**：提供多种优化技术和策略
-
-数据湖上的SQL分析结合了传统SQL的易用性和大数据处理的灵活性、可扩展性，使其成为现代数据分析的强大工具。通过本文的GitHub事件数据分析案例，我们展示了如何使用SQL直接查询和分析存储在数据湖Volume上的JSON文件，从而快速获取有价值的数据洞察。

-# 探索和分析数据湖Volume上的Parquet文件里的数据
-
-## 引言
-
-数据湖是Lakehouse的重要组成部分，允许您以原始格式存储所有结构化和非结构化数据，无需事先定义模式，这充分体现了湖仓一体的优势，将Lakehouse的数据管理扩展到对非结构化数据的一体化管理，不再局限于数仓里的结构化数据管理。本文将介绍如何利用SQL在Lakehouse环境中探索和分析存储在Volume上的Parquet文件数据，以纽约市出租车数据分析为实例，展示数据探索的完整过程和方法。
-
-## Parquet格式简介
-
-Parquet是一种列式存储格式，专为大数据处理而设计，具有以下主要特点：
-
-* **列式存储**：数据按列而非按行存储，特别适合于分析查询
-* **高效压缩**：相比传统行式存储如CSV，可节省50-75%的存储空间
-* **高性能**：支持谓词下推(predicate pushdown)，允许查询引擎仅读取需要的列和行
-* **自包含元数据**：文件包含模式定义，支持自描述
-* **广泛兼容**：被Hadoop、Spark、Presto等大数据工具广泛支持
-
-Parquet格式特别适合存储和查询大规模的结构化数据，如日志数据、事务数据和传感器数据，非常适合数据湖场景。
-
-## 数据湖Volume概念
-
-在Lakehouse平台中，Volume是一个关键概念：
-
-* **Volume**是数据湖中的逻辑存储单元，类似于传统数据库中的表空间
-* Volume可以指向内部存储或外部存储(如OSS、S3、HDFS等)
-* 通过Volume机制，数据湖可以直接查询外部存储系统中的数据，无需导入
-* 每个Volume可以包含多个文件，支持目录层次结构
-
-本文以`yellow_trip_record_data`为例，这是一个指向外部对象存储的Volume，包含纽约市黄色出租车的行程数据。
-
-## 样例数据介绍
-
-本文使用的纽约市出租车数据(NYC Yellow Taxi Trip Records)是一个公开的交通数据集：
-
-* 数据存储在名为`yellow_trip_record_data`的Volume中
-* 数据以Parquet格式存储，按月份组织
-* 文件命名格式为`yellow_tripdata_YYYY-MM.parquet`（例如：`yellow_tripdata_2024-01.parquet`表示2024年1月的数据）
-* 每个文件包含该月份所有黄色出租车行程的详细记录
-* 数据包含上下车时间、地点、费用、乘客数等丰富信息
-
-这些数据可用于分析城市交通模式、出租车需求、价格趋势等多方面内容。

-
-## 1. 数据湖Volume基础操作
-
-在开始分析前，需要了解和掌握数据湖Volume的基础操作，这是与数据交互的第一步。
-
-### 1.1 列出可用Volume
-
-```sql
-SHOW VOLUMES;
-```
-
-通过此命令可以查看所有可用的数据卷，包括Volume名称、创建时间、类型(内部/外部)、URL地址等信息。在我们的示例中，这个命令会显示包括`yellow_trip_record_data`在内的所有可用Volume。
-
-执行结果示例：
-
-```
-volume_name: yellow_trip_record_data
-create_time: 2025-05-14T06:40:56.571000+00:00
-external: true
-workspace_name: ns227206
-url: oss://tlc-trip-record-data/yellow-trip-record-data/
-recursive_file_lookup: true
-connection: ns227206.oss_sh_conn_ak
-```
-
-从结果可以看出，这是一个外部Volume，指向OSS对象存储中的一个路径，并且启用了递归文件查找选项。
-
-### 1.2 列出Volume中的文件
-
-```sql
-LIST VOLUME yellow_trip_record_data SUBDIRECTORY '/';
-```
-
-此命令将显示指定Volume根目录中的所有文件，包括文件相对路径、完整URL、文件大小和最后修改时间等信息。`SUBDIRECTORY '/'`表示查看根目录下的文件，如果数据有层次结构，可以指定子目录路径。
-
-执行结果示例：
-
-```
-relative_path: yellow_tripdata_2024-01.parquet
-url: oss://tlc-trip-record-data/yellow-trip-record-data/yellow_tripdata_2024-01.parquet
-size: 49961641
-last_modified_time: 2025-05-14T12:02:21+00:00
-
-relative_path: yellow_tripdata_2024-02.parquet
-...
-```
-
-此结果显示Volume中包含多个按月命名的Parquet文件，每个约50MB大小，包含2024年1月至2025年2月的数据。
-
-## 2. 初步数据探索
-
-在处理不熟悉的数据集时，首先需要了解数据的整体情况，建立对数据内容和结构的初步认识。
-
-### 2.1 列出文件
-
-对于我们的示例数据集，首先列出所有可用的数据文件：
-
-```sql
-LIST VOLUME yellow_trip_record_data SUBDIRECTORY '/';
-```
-
-执行该命令后，我们看到Volume中包含多个Parquet文件，命名模式为`yellow_tripdata_YYYY-MM.parquet`。
-
-### 2.2 了解文件格式和命名规则
-
-通过观察文件名(如`yellow_tripdata_2024-01.parquet`)，我们可以了解到:
-
-* 文件格式为Parquet（通过.parquet后缀识别）
-* 命名规则为"yellow\_tripdata\_年份-月份.parquet"
-* 数据按月份组织，覆盖2024年1月至2025年2月
-* 每个文件大小约为50-60MB
-
-这种命名和组织方式是数据湖中常见的分区策略，按时间维度分割数据，方便查询特定时间段的数据并提高查询效率。
-
-### 2.3 了解数据来源和背景
-
-纽约出租车与豪华轿车委员会(TLC)收集的黄色出租车行程记录数据包含出租车行程的上下车日期/时间、位置、行程距离、详细费用、费率类型、付款方式等信息。此类公共交通数据对城市规划、交通管理和商业决策具有重要价值。
-
-## 3. 数据预览
-
-在深入分析前，先预览数据结构和内容至关重要，这样可以了解数据的质量、格式和可能的分析方向。
-
-### 3.1 预览Parquet文件内容
-
-Clickzetta允许我们直接使用SQL查询来预览Parquet文件的内容，无需先创建表或导入数据：
-
-```sql
-SELECT * FROM VOLUME yellow_trip_record_data
-USING parquet
-FILES('yellow_tripdata_2024-01.parquet')
-LIMIT 10;
-```
-
-这个查询语法的关键部分：
-
-* `FROM VOLUME yellow_trip_record_data`：指定数据来源是哪个Volume
-* `USING parquet`：声明文件格式为Parquet
-* `FILES('yellow_tripdata_2024-01.parquet')`：指定要查询的具体文件
-* `LIMIT 10`：只返回前10条记录，用于快速预览
-
-执行结果示例：
-
-```
-VendorID: 2
-tpep_pickup_datetime: 2024-01-01T00:57:55
-tpep_dropoff_datetime: 2024-01-01T01:17:43
-passenger_count: 1
-trip_distance: 1.72
-RatecodeID: 1
-store_and_fwd_flag: N
-PULocationID: 186
-DOLocationID: 79

-
-通过这种初步检查，我们现在了解了数据的结构和字段含义，为后续的分析奠定了基础。
-
-## 4. 基础数据分析
-
-获取数据基本概况，包括数量统计、平均值和异常值检测。
-
-### 4.1 基础统计分析
-
-```sql
-SELECT 
-  COUNT(*) as total_trips,
-  AVG(trip_distance) as avg_distance,
-  MIN(trip_distance) as min_distance,
-  MAX(trip_distance) as max_distance,
-  AVG(total_amount) as avg_fare,
-  MIN(total_amount) as min_fare,
-  MAX(total_amount) as max_fare,
-  AVG(TIMESTAMPDIFF(MINUTE, tpep_pickup_datetime, tpep_dropoff_datetime)) as avg_trip_duration_minutes
-FROM VOLUME yellow_trip_record_data
-USING parquet
-FILES('yellow_tripdata_2024-01.parquet');
-```
-
-### 4.2 分类分析
-
-分析分类变量(如支付方式)的分布情况:
-
-```sql
-SELECT 
-  payment_type,
-  COUNT(*) as trip_count,
-  ROUND(COUNT(*) * 100.0 / (SELECT COUNT(*) FROM VOLUME yellow_trip_record_data USING parquet FILES('yellow_tripdata_2024-01.parquet')), 2) as percentage
-FROM VOLUME yellow_trip_record_data
-USING parquet
-FILES('yellow_tripdata_2024-01.parquet')
-GROUP BY payment_type
-ORDER BY trip_count DESC;
-```
-
-### 4.4 热点区域分析
-
-```sql
--- 最热门的上车地点
-SELECT 
-  PULocationID,
-  COUNT(*) as pickup_count,
-  ROUND(AVG(trip_distance), 2) as avg_distance,

-FROM VOLUME yellow_trip_record_data
-USING parquet
-FILES('yellow_tripdata_2024-01.parquet')
-GROUP BY PULocationID
-ORDER BY pickup_count DESC
-LIMIT 5;
-```
-
-**执行结果**：
-
-```
-| PULocationID | pickup_count | avg_distance | avg_fare |
-|--------------|--------------|--------------|----------|
-| 132          | 145240       | 15.49        | 76.58    |
-| 161          | 143471       | 2.56         | 23.48    |

-| 162          | 106717       | 2.23         | 22.88    |
-```
-
-该查询揭示了最受欢迎的上车点：
-
-* PULocationID 132是最热门的上车点，有145,240次乘车
-* 该区域平均行程距离显著高于其他区域（15.49英里），平均费用也最高（76.58美元），这表明它可能是一个主要机场或交通枢纽
-* 其他热门上车点（如161、237、236和162）的平均行程距离和费用明显低于132，可能是市区热门位置
-
-### 4.5 数值分布分析
-
-```sql
--- 行程距离与价格的分布
-SELECT 
-  CASE 
-    WHEN trip_distance BETWEEN 0 AND 1 THEN '0-1'
-    WHEN trip_distance BETWEEN 1 AND 2 THEN '1-2'
-    WHEN trip_distance BETWEEN 2 AND 3 THEN '2-3'
-    WHEN trip_distance BETWEEN 3 AND 5 THEN '3-5'
-    WHEN trip_distance BETWEEN 5 AND 10 THEN '5-10'
-    ELSE '10+'
-  END AS distance_range,
-  COUNT(*) as trip_count,
-  ROUND(AVG(total_amount), 2) as avg_fare
-FROM VOLUME yellow_trip_record_data
-USING parquet
-FILES('yellow_tripdata_2024-01.parquet')
-WHERE trip_distance <= 100 -- 过滤掉异常值
-GROUP BY distance_range
-ORDER BY CASE 
-    WHEN distance_range = '0-1' THEN 1
-    WHEN distance_range = '1-2' THEN 2
-    WHEN distance_range = '2-3' THEN 3
-    WHEN distance_range = '3-5' THEN 4
-    WHEN distance_range = '5-10' THEN 5
-    ELSE 6
-  END;
-```
-
-**执行结果**：
-
-```
-| distance_range | trip_count | avg_fare |
-|----------------|------------|----------|
-| 0-1            | 778076     | 15.00    |
-| 1-2            | 967440     | 18.37    |
-| 2-3            | 448775     | 23.83    |
-| 3-5            | 308574     | 30.39    |

-| 10+            | 228195     | 83.41    |
-```
-
-这个分析提供了行程距离和费用之间关系的重要见解：
-
-* 1-2英里是最常见的行程距离范围，有967,440次行程
-* 短距离行程（0-3英里）占总行程的73.7%
-* 行程距离与平均费用呈明显的正相关关系
-* 10英里以上的长途行程均价高达83.41美元，是短途行程（0-1英里）均价的5.5倍
-
-```sql
-SELECT 
-  CASE 
-    WHEN trip_distance BETWEEN 0 AND 1 THEN '0-1'
-    WHEN trip_distance BETWEEN 1 AND 2 THEN '1-2'
-    WHEN trip_distance BETWEEN 2 AND 3 THEN '2-3'
-    WHEN trip_distance BETWEEN 3 AND 5 THEN '3-5'
-    WHEN trip_distance BETWEEN 5 AND 10 THEN '5-10'
-    WHEN trip_distance BETWEEN 10 AND 20 THEN '10-20'
-    WHEN trip_distance > 20 THEN '20+'
-    ELSE 'Unknown'
-  END AS distance_range,
-  COUNT(*) as trip_count,
-  ROUND(AVG(total_amount), 2) as avg_fare
-FROM VOLUME yellow_trip_record_data
-USING parquet
-FILES('yellow_tripdata_2024-01.parquet')
-WHERE trip_distance <= 100 -- 过滤掉异常值
-GROUP BY distance_range
-ORDER BY CASE 
-    WHEN distance_range = '0-1' THEN 1
-    WHEN distance_range = '1-2' THEN 2
-    WHEN distance_range = '2-3' THEN 3
-    WHEN distance_range = '3-5' THEN 4
-    WHEN distance_range = '5-10' THEN 5
-    WHEN distance_range = '10-20' THEN 6
-    WHEN distance_range = '20+' THEN 7
-    ELSE 8
-  END;
-```
-
-## 5. 高级分析和聚合
-
-更深入的数据分析，包括多维度聚合、热点分析等。
-
-### 5.1 时间维度聚合
-
-```sql
--- 每小时行程分布
-SELECT 
-  HOUR(tpep_pickup_datetime) as hour_of_day,
-  COUNT(*) as trip_count,
-  ROUND(AVG(trip_distance), 2) as avg_distance,
-  ROUND(AVG(total_amount), 2) as avg_fare
-FROM VOLUME yellow_trip_record_data
-USING parquet
-FILES('yellow_tripdata_2024-01.parquet')
-GROUP BY hour_of_day
-ORDER BY hour_of_day ASC;
-```
-
-### 5.2 热点区域分析
-
-```sql

-```
-
-## 6. 时间序列分析
-
-分析多个时间段的数据变化趋势。
-
-### 6.1 多月份数据合并分析
-
-由于无法直接通过文件名变量引用多个文件，可以使用以下方法处理多月份数据:
-
-```sql
--- 使用CTE合并多月数据
-WITH jan AS (
-  SELECT 
-    '2024-01' as month,
-    COUNT(*) as trip_count,
-    ROUND(AVG(trip_distance), 2) as avg_distance,
-    ROUND(AVG(total_amount), 2) as avg_fare
-  FROM VOLUME yellow_trip_record_data
-  USING parquet
-  FILES('yellow_tripdata_2024-01.parquet')
-  WHERE trip_distance <= 100
-),
-feb AS (
-  SELECT 
-    '2024-02' as month,
-    COUNT(*) as trip_count,
-    ROUND(AVG(trip_distance), 2) as avg_distance,
-    ROUND(AVG(total_amount), 2) as avg_fare
-  FROM VOLUME yellow_trip_record_data
-  USING parquet
-  FILES('yellow_tripdata_2024-02.parquet')
-  WHERE trip_distance <= 100
-)
-SELECT * FROM jan
-UNION ALL SELECT * FROM feb
-ORDER BY month;
-```
-
-### 6.2 季度数据分析
-
-```sql
--- 分析各季度支付方式趋势
-WITH q1 AS (
-  SELECT 
-    '2024-Q1' as quarter,
-    payment_type,
-    COUNT(*) as payment_count
-  FROM VOLUME yellow_trip_record_data
-  USING parquet
-  FILES('yellow_tripdata_2024-01.parquet', 'yellow_tripdata_2024-02.parquet', 'yellow_tripdata_2024-03.parquet')
-  GROUP BY quarter, payment_type
-),
-q2 AS (
-  SELECT 
-    '2024-Q2' as quarter,
-    payment_type,
-    COUNT(*) as payment_count
-  FROM VOLUME yellow_trip_record_data
-  USING parquet
-  FILES('yellow_tripdata_2024-04.parquet', 'yellow_tripdata_2024-05.parquet', 'yellow_tripdata_2024-06.parquet')
-  GROUP BY quarter, payment_type
-)
-SELECT * FROM q1
-UNION ALL SELECT * FROM q2
-ORDER BY quarter, payment_type;
-```
-
-## 7. 最佳实践和优化技巧
-
-### 7.1 数据过滤
-
-在处理大数据时，合理的过滤条件可以大幅提高查询效率:
-
-```sql
--- 使用WHERE子句过滤异常值
-SELECT 
-  COUNT(*) as trip_count,
-  ROUND(AVG(trip_distance), 2) as avg_distance
-FROM VOLUME yellow_trip_record_data
-USING parquet
-FILES('yellow_tripdata_2024-01.parquet')
-WHERE 
-  trip_distance BETWEEN 0.5 AND 100 AND  -- 排除可能的异常距离
-  total_amount > 0 AND                   -- 排除免费或错误记录的行程
-  passenger_count > 0;                   -- 排除无乘客记录
-```
-
-有效的过滤条件能够：
-
-* 排除数据异常值，提高分析结果的准确性
-* 减少处理的数据量，提高查询性能
-* 专注于最相关的数据子集，满足特定的分析需求
-
-### 7.2 列剪裁和谓词下推
-
-充分利用Parquet格式的列式存储和谓词下推特性：
-
-```sql
--- 只选择需要的列而非所有列
-SELECT 
-  tpep_pickup_datetime,
-  tpep_dropoff_datetime,
-  trip_distance,
-  total_amount
-FROM VOLUME yellow_trip_record_data
-USING parquet
-FILES('yellow_tripdata_2024-01.parquet')
-WHERE HOUR(tpep_pickup_datetime) BETWEEN 8 AND 10  -- 利用谓词下推只读取需要的行
-LIMIT 1000;
-```
-
-这种优化策略能够：
-
-* 减少I/O量，仅读取查询所需的列数据
-* 利用Parquet内置的过滤能力，在文件里跳过不符合条件的数据块
-* 显著提高大数据集上的查询性能
-
-### 7.3 分阶段分析
-
-对于大型数据集，采用分阶段分析策略:
-
-1. 先在单个文件上进行探索性分析
-2. 验证分析逻辑后再扩展到全部数据
-3. 使用CTE组织复杂查询，增强可读性和可维护性
-
-```sql
--- 使用CTE简化复杂查询
-WITH hourly_stats AS (
-  SELECT 
-    HOUR(tpep_pickup_datetime) as hour_of_day,
-    COUNT(*) as trip_count,
-    AVG(trip_distance) as avg_distance
-  FROM VOLUME yellow_trip_record_data
-  USING parquet
-  FILES('yellow_tripdata_2024-01.parquet')
-  GROUP BY HOUR(tpep_pickup_datetime)
-),
-peak_hours AS (
-  SELECT 
-    hour_of_day,
-    trip_count,
-    avg_distance,
-    RANK() OVER (ORDER BY trip_count DESC) as popularity_rank
-  FROM hourly_stats
-)
-SELECT * FROM peak_hours
-WHERE popularity_rank <= 5
-ORDER BY popularity_rank;
-```
-
-这种方法使得复杂查询更易于理解、调试和维护。
-
-### 7.4 数据质量检查
-
-在分析前进行数据质量检查:
-
-```sql
--- 检查缺失值和异常值
-SELECT 
-  COUNT(*) as total_records,
-  SUM(CASE WHEN passenger_count IS NULL OR passenger_count = 0 THEN 1 ELSE 0 END) as missing_passenger_count,
-  SUM(CASE WHEN trip_distance IS NULL OR trip_distance = 0 THEN 1 ELSE 0 END) as zero_distance,
-  SUM(CASE WHEN trip_distance > 100 THEN 1 ELSE 0 END) as suspicious_long_trips,
-  SUM(CASE WHEN total_amount < 0 THEN 1 ELSE 0 END) as negative_fares
-FROM VOLUME yellow_trip_record_data
-USING parquet
-FILES('yellow_tripdata_2024-01.parquet');
-```
-
-数据质量检查能够：
-
-* 发现数据中的问题和异常
-* 指导后续分析中的数据清理和转换
-* 提高分析结果的可靠性和准确性
-
-## 结论
-
-通过SQL方式直接分析数据湖Volume中的Parquet文件，我们可以:
-
-1. 快速探索和了解数据结构
-2. 进行全方位的统计分析
-3. 发现数据中的时间和空间模式
-4. 比较不同时间段的数据变化趋势
-
-这种方法避免了数据复制和转换的开销，直接在数据湖上进行分析，提高了效率。对于大数据环境，这种分析方式既灵活又高效，特别适合数据科学家和分析师进行数据探索和初步分析。
-
-通过本文的纽约出租车数据案例，我们展示了从基础的数据探索到复杂的时间序列分析的完整流程，为数据湖环境下的Parquet文件分析提供了实用指南。与传统的先导入后分析的方法相比，这种直接查询方法极大地提高了数据分析的灵活性和响应速度，特别适合于初步数据探索和验证分析假设。
-
-在实际项目中，这些分析可以为出租车公司优化车辆调度、城市管理部门改善交通规划、金融分析师了解消费趋势等多种场景提供数据支持。数据湖上的SQL分析正成为连接原始数据和商业洞察的关键桥梁。

-# Lakehouse 列级安全（动态脱敏）使用文档
-> 【预览发布】本功能当前处于受邀预览发布阶段。如需使用，请联系我们的技术支持团队协助处理。
-## 1. 概述
-
-列级安全（Column-level Security）通过动态脱敏（Dynamic Data Masking）提供细粒度数据保护能力，可根据用户身份或角色动态修改敏感数据的显示方式（如部分隐藏、替换字符）。系统仅存储原始数据，在数据读取运行时才执行脱敏函数（mask function）。本文档介绍如何通过 SQL 接口实现此功能。
-
-## 2. 核心语法
-
-### 2.1 创建脱敏策略函数
-
-参考[CREATE FUNCTION(SQL)](create-sql-function.md)语法
-
-```sql
-CREATE  FUNCTION [schema_name.]function_name (col_name column_type) 
-RETURNS output_type 
-AS 
-expression_with_conditional_logic;
-```
-
-**关键要素**：
-
-* 必须返回与原始列相同的数据类型
-* 使用安全上下文函数：
-  * `current_user()` 获取当前用户（注意大小写）
-  * `current_roles()` 获取用户角色数组
-
-### 2.2 绑定策略到列
-
-**创建表时指定**：
-
-```sql
-CREATE TABLE table_name (
-  col1 STRING MASK schema_name.masking_function,
-  ...
-);
-```
-
-**修改已有表**：
-
-```sql
-ALTER TABLE table_name 
-CHANGE COLUMN column_name 
-SET MASK schema_name.masking_function;
-```

-
-***
-
-## 3. 使用场景示例
-
-### 3.1 基础脱敏
-
-**需求**：身份证号前6位+4星号+后4位
-
-```sql
-CREATE FUNCTION public.idcard_masking(idcard STRING)
-RETURNS STRING
-AS concat(substr(idcard, 1, 6), repeat('*', 4), substr(idcard, 10, 4));
-

-
-**查询效果**：
-
-```
-原始值：130183199901011234 → 脱敏后：130183****9010
-```
-
-### 3.2 基于用户的动态脱敏
-
-**需求**： 仅UAT\_TEST用户看到脱敏数据
-
-```sql
-CREATE FUNCTION public.idcard_masking(idcard STRING)
-RETURNS STRING
-AS 
-CASE 
-  WHEN current_user() = "UAT_TEST" 
-  THEN concat(substr(idcard, 1, 6), repeat('*', 4), substr(idcard, 10, 4))
-  ELSE idcard 
-END;
---忽略用户名大小写
-CREATE FUNCTION public.idcard_masking(idcard STRING)
-RETURNS STRING
-AS 
-CASE 
-  WHEN lower(current_user()) = "uat_test" 
-  THEN concat(substr(idcard, 1, 6), repeat('*', 4), substr(idcard, 10, 4))
-  ELSE idcard 
-END;
-```
-
-### 3.3 基于角色的动态脱敏
-
-**需求**： user\_admin角色可查看完整信息
-
-```sql
-CREATE FUNCTION public.idcard_masking_role(idcard STRING)
-RETURNS STRING
-AS 
-CASE 
-  WHEN array_contains(current_roles(), "user_admin") 
-  THEN idcard
-  ELSE concat(substr(idcard,1,6), '****', substr(idcard,11,4)) 
-END;
-```
-
-***
-
-## 4. 完整操作示例
-
-### 4.1 初始化环境
-
-```sql
-CREATE SCHEMA IF NOT EXISTS security_demo;
-USE security_demo;
--- 通用掩码函数
-CREATE FUNCTION security_demo.ssn_mask(ssn STRING)
-RETURNS STRING
-AS concat('***-**-', substr(ssn, 8, 4));
-
-CREATE TABLE security_demo.user_data (
-  name STRING,
-  ssn STRING MASK security_demo.ssn_mask,  -- 建表时直接绑定
-  phone STRING
-);
-INSERT INTO security_demo.user_data VALUES('James', '123-45-6789','123456789');
-SELECT * FROM      security_demo.user_data;
-```
-
-### 4.2 创建策略函数
-
-```sql
--- 特权角色豁免
-CREATE FUNCTION security_demo.admin_ssn_mask(ssn STRING)
-RETURNS STRING
-AS 
-CASE
-  WHEN array_contains(current_roles(), 'user_admin') THEN ssn
-  ELSE concat('***-**-', substr(ssn,8,4))
-END;
-```
-
-### 4.3 修改脱敏策略
-
-```sql
---去除之前的策略
-ALTER TABLE security_demo.user_data CHANGE COLUMN ssn UNSET MASK;
-
---添加新的策略
-ALTER TABLE security_demo.user_data CHANGE COLUMN ssn SET MASK security_demo.admin_ssn_mask;
-```
-
-### 4.4 验证效果
-
-**普通用户查询**：
-
-```sql
-SELECT * FROM user_data;
--- 输出：John Doe ***-**-6789 138****1234
-```
-
-**USER\_ADMIN角色查询**：
-
-```sql
-SELECT * FROM user_data; 
--- 输出：John Doe 123-45-6789 138****1234
-```
-
-***
-
-## 5. 管理注意事项
-
-### 5.1 权限控制
-
-* 仅允许具有 `ALTER TABLE` 权限的角色修改脱敏策略。
-* 函数创建需要 `CREATE FUNCTION` 权限。
-
-### 5.2 性能建议
-
-* 避免在脱敏函数中使用复杂计算。
-* 对高频查询列，谨慎使用条件判断逻辑。
-
-## 6. 限制说明
-
-* 单个列只能绑定一个脱敏策略。如果您想定义多种脱敏规则，可以在一个函数中基于条件判断实现不同的策略。

-# 动态表简介
-【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请联系我们的技术支持同学协助处理。
-
-## 什么是动态表
-
-动态表（Dynamic Table）是云器Lakehouse的数据对象。创建时与表的区别是通过定义查询语句动态生成数据，刷新时自动获取Base Table的增量数据，采用增量算法进行计算，这样做的优势是大幅提升数据处理效率，尤其适用于处理大规模数据。
-
-## 动态表应用场景
-
-### 面向实时加工场景
-
-在实时数据加工场景中，数据以持续且快速的方式流入系统。传统的数据处理方法，如完全重载（Full Reload）或全量刷新（Full Refresh），在性能和资源消耗方面可能不够高效，特别是在处理大规模数据流时。动态表采用增量计算方法，仅处理自上次更新以来变化的数据，从而显著减少了计算资源的消耗。
-
-**动态表的优势**：
-
-* **实时性**：能够迅速将新数据变更反映到数据仓库中，保持数据的高新鲜度。
-* **成本效益**：通过设置合理的刷新间隔，可以平衡性能与成本，实现资源的最优利用。
-* **资源弹性**：Lakehouse的资源可以轻松实现弹性扩展，尤其在处理峰值数据流入时更具优势。
-* **按需计算**：未来Lakehouse将实现按需启动计算资源，即仅在有数据需要计算时才会启动相应资源，进一步提高效率和降低成本。
-
-**应用实例**：
-
-**背景**： 一家电子商务公司希望实时分析其销售数据，以便快速做出库存和定价决策。数据以高速率持续流入系统，需要一种高效的数据处理方法。
-
-**挑战**：
-
-* 传统的全量数据处理方法在性能和资源消耗方面效率低下，尤其是在高峰时段。
-* 需要一种能够快速响应数据变更并保持数据新鲜的处理机制。
-
-**解决方案**：
-
-* 引入动态表，采用增量计算方法，仅处理自上次更新以来变化的数据。
-
-**动态表的优势**：
-
-1. **实时性**： 动态表能够迅速捕捉并反映数据变更，确保决策基于最新的销售数据。
-
-2. **成本效益**：通过动态表，公司可以根据实际需求设置合理的数据刷新间隔，避免了不必要的计算资源浪费。
-
-3. **资源弹性**：在促销活动或节假日等流量高峰时段，Lakehouse的资源可以按需扩展，以应对数据流入的峰值，而不必长期维持高额的资源配置。
-
-4. **按需计算**：未来，Lakehouse的按需计算功能将进一步提高效率，仅在有数据需要计算时才启动资源，从而降低成本。
-
-### 数据新鲜度要求较高的**固定维度分析查询场景**
-
-在固定维度分析查询场景中，我们追求的是能够提供近乎实时的分析结果。传统的视图查询可以实现这一点，但如果涉及大量数据转换，则可能会导致查询速度变慢。为了解决这个问题，我们可以将转换后的结果进行物化，这样在查询时就可以直接返回这些结果，从而提高查询速度。物化结果可以采用传统的表格或者dynamic table。
-
-使用传统的表可以提供最高的性能，因为它们在查询时只返回预先转换好的数据。但这种方法的缺点是，需要定期评估数据转换的时间，并通过调度进行全量计算，这通常会占用较长的时间。
-
-dynamic table结合了增量计算的优势。通过仅更新自上次加载以来发生变化的记录，dynamic table不仅减少了每次构建的时间，通过缩短时间间隔还保持了数据的最新性。
-
-### 注意事项
-
-* 在处理源端大量变化数据时，计算任务可能接近全量计算的负载。尽管增量计算在效率上具有明显优势，但如果您设置的刷新间隔过短，可能会导致任务积压。这是因为每次刷新操作本身需要一定的时间来完成，如果这个时间超过了您设置的刷新间隔，将会导致后续刷新任务的排队等待。
-  * **建议**：
-    * **合理设置刷新间隔**：根据数据变更的频率和任务的刷新耗时，合理设置刷新间隔，以避免刷新操作的积压。
-    * **监控和调整**：持续监控数据变更模式和系统性能，根据实际情况调整刷新间隔，以实现效率和资源的最优化利用。
-* 在编写算子时，请参考《算子是如何增量刷新》中的注意事项来优化增量刷新任务。
-
-## 动态表工作原理概述
-
-### 如何获取变化的数据
-
-* MetaService（元数据服务，Lakehouse 的一个组件服务）记录了 Lakehouse 里每张表的每一个历史数据版本

-  * 基本概念：一张表的 **Snapshot（全量）** VS **Delta（变化）**

-## **Lakehouse Dynamic Table 刷新机制**
-
-Lakehouse 目前使用调度机制来更新 Dynamic Table。支持以下几种调度模式：
-
-1. **在 DDL 语句中定义调度属性**
-2. **在 Lakehouse Studio 中定义调度**
-3. **使用第三方调度引擎提交 Refresh 作业**
-
-|                          | 使用方式                                                                                                    | 优点                                                        | 缺点                                                                                    |
-| ------------------------ | ------------------------------------------------------------------------------------------------------- | --------------------------------------------------------- | ------------------------------------------------------------------------------------- |
-| DDL语句中定义调度属性             | 在refreshOption中定义刷新间隔，具体使用方式[参考动态表创建文档](<create-dynamic-table.md>)。目前限制刷新间隔一分钟。 | 简单易用，可以快速设置刷新选项。不依赖任何第三方工具。                               | 当前Lakehouse不支持在 Dynamic Table 上定义严格的上下游依赖关系。在 DDL 定义中依赖时间调度。可以通过时间间隔的方式先保证上游刷新完成再调度下游 |
-| 在 Lakehouse Studio 中定义调度 | 可以在 Lakehouse Studio 中通过可视化界面配置调度，具体配置方式可以参考[任务开发调度文档](taskdevelop.md)。目前限制刷新间隔一分钟。                     | 可视化配置，用户友好。支持调度依赖配置，确保上游刷新完成后再刷新下游。支持单节点运行监控，如失败告警、超时告警等。 |                                                                                       |
-| 使用第三方调度引擎提交 Refresh 作业   | 通过下载 Lakehouse 客户端命令，使用 cron 表达式定时提交 Refresh 任务。或者通过 Java Jdbc 接口自定义提交 Refresh 命令。                      | 您可以更灵活地控制作业的提交和配置调度信息，时间间隔没有限制                            | 需要依赖第三方调度。引入第三方调度系统                                                                   |
-
-## 动态表和物化视图、普通视图的比较
-
-从Lakehouse的实现机制上来看，动态表是基于传统的物化视图来演进的，虽然两者有一些共性，但是定位上存在很大区别
-
-|       | 物化视图                                        | 动态表                         | 普通视图                                              |
-| ----- | ------------------------------------------- | --------------------------- | ------------------------------------------------- |
-| 定义    | 一种预计算并存储查询结果的特殊视图                           | 专注于数据加工的高效工具                | 一种虚拟表，不存储数据，只保存查询定义                               |
-| 性能优化  | 显著提升查询效率，通过预存结果减少重复计算。其他 SQL可以利用该物化结果进行查询改写 | 虽然也可以提高查询效率，但是查询优化器不会进行查询改写 | 性能取决于底层数据表的查询效率,查询是计算逻辑每次重新计算                     |
-| 数据时效性 | 要求数据即时更新，以确保查询改写的准确性                        | 注重数据加工灵活性，可调整数据滞后性          | 数据新鲜度每次都是最新的                                      |
-| 更新机制  | 采用定时刷新机制，保持数据最新                             | 根据业务定义调整，不强制实时更新            | 不存储数据无需更新                                         |
-| 查询优化  | 优化器自动识别并使用预存结果                              | 不依赖于查询优化器的自动重写              |                                                   |
-| 使用场景  | 适合于预计算并复用查询结果的场景                            | 适合数据加工，可能数据不是最新的            | 适合于查询复杂度不高不涉及大量加工,如果涉及大数据量和很多复杂算子，查询很慢，因为每次都是重新计算 |
-| 运维    | 无复杂运维场景                                     | 动态表还支持了复杂的加列，版本回滚等功能        | 无复杂运维场景                                           |

-动态表的刷新操作依赖于计算资源（Virtual Cluster）来执行，包括：
-
-* **定时刷新**：根据设定的时间间隔自动执行刷新。
-* **手动刷新**：用户根据需要手动触发刷新。
-
-这些刷新操作均会消耗计算资源。
-
-#### **存储成本**
-
-动态表同样需要存储空间来保存其具体化结果。与常规表一样，动态表支持：
-
-* **Time Travel**：允许用户访问过去7天内的任何时间点的数据。
-* **Time Travel 保留期限**：默认设置为7天，超过此期限后，数据将无法通过Time Travel访问，并且会被物理删除。
-
-**注意**：Time Travel 目前处于预览版，其默认保留周期为7天。在预览期间，用户可以免费查询7天内的数据版本，且不会对这段时间内的版本收费。预览期结束后，Lakehouse 将开始对使用 Time Travel 功能产生的存储费用进行单独计费。
-
-#### **刷新调度设置周期**
-
-**刷新速度影响因素**
-
-增量刷新的速度主要取决于两个因素：
-
-1. **源数据的变更量**：刷新操作需要处理的数据量越大，所需的时间就越长。
-2. **固定开销**：无论数据变更量大小，每次刷新都会产生的一些基本开销。
-
-**商业价值与刷新频率**
-
-* 如果数据新鲜度对您的业务价值不是至关重要，可以考虑降低刷新频率。这种策略可以减少因频繁刷新带来的计算开销。
-* 采用增量计算模式可以提高单次刷新的速度，因为它只处理自上次刷新以来发生变化的数据。
-
-**刷新成本与频率的平衡**
-
-* 刷新成本会随着刷新频率的增加而上升。因此，您需要在数据新鲜度所带来的商业价值和由此产生的计算成本之间做出权衡。
-* 高频率的刷新操作虽然可以保持数据的实时更新，但累积的计算成本也会随之增加。
-
-**建议**
-
-* 评估您的业务需求，确定数据新鲜度对您业务的具体价值。
-* 根据业务价值来设定合理的刷新频率，以优化成本效益。
-* 利用增量计算模式来提高刷新效率，减少不必要的计算开销。
-
-## 动态表限制
-
-* 增量刷新限制：不支持非确定性函数，比如random、current\_timestamp、current_date等
-* 不支持直接修改动态表数据，比如执行update、delete、truncate数据
-
-# 使用动态表加工案例
-
-## 使用动态表加工Lakehouse提供的样例数据
-
-Lakehouse 提供了一个名为 `ecommerce_events_multicategorystore_live` 的动态公共数据集，该数据集位于 `clickzetta_sample_data.clickzetta_sample_data.ecommerce_events_history` 路径下。这个数据集是实时更新的，并且可以被直接查询。
-
-实时数据集可用性：目前，`ecommerce_events_multicategorystore_live` 实时写入的公共数据集只在阿里云的上海区域提供。如果您的账户或服务不在该区域，您将无法查询此公共数据集。
-
-1. **编写SQL脚本使用DDL定义调度加工数据**
-
-```SQL
-CREATE  DYNAMIC TABLE event_type_count
-REFRESH interval 1 minute vcluster default
-as
-SELECT event_type, COUNT(*) AS events_count
-FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live
-GROUP BY event_type;
---初始化DYNAMIC TABLE数据
-REFRESH DYNAMIC TABLE event_type_count;
-```
-
-2. 查看动态表刷新
-
-**使用命令查看动态表刷新**
-
-```SQL
-SHOW DYNAMIC TABLE REFRESH HISTORY WHERE name='event_type_count';
-```
-
-**在作业历史中查看dynamic table刷新历史**
-
-![](.topwrite/assets/image_1716280651911.png)
-
-点进详情中可以查看输入记录可以看到获取了增量多少条，诊断中可以查看增量执行SQL的计划
-
-![](.topwrite/assets/image_1716280668286.png)
-
-3. **在作业历史中看到增量刷新有数据后，可以查看数据变化**
-
-```SQL
-SELECT    *   FROM      event_type_count;
-+-------------+--------------+
-| event_type  | events_count |
-+-------------+--------------+
-| view        | 91634700     |
-| purchase    | 91630921     |
-| add_to_cart | 91622270     |
-+-------------+--------------+
---增量刷新完成后查看数据
-SELECT    *
-FROM      event_type_count;
-+-------------+--------------+
-| event_type  | events_count |
-+-------------+--------------+
-| purchase    | 91633135     |
-| add_to_cart | 91624515     |
-| view        | 91636913     |
-+-------------+--------------+
-```
-
-## 使用STUDIO刷新调度动态表刷新任务
-
-在本次演示中，我们将通过以下步骤模拟增量数据的插入，并展示增量计算的效果：
-
-* **模拟增量数据插入**：使用 `INSERT INTO` 语句将模拟数据插入到指定表中，以此来模拟实际业务场景中的增量数据更新。
-* **利用 Studio 调度刷新**：随后，我们将利用 Lakehouse Studio 的调度功能来触发和执行增量数据的刷新任务。
-* **演示增量计算效果**：通过上述步骤，我们旨在展示增量计算如何高效地处理新插入的数据，并将更新反映在最终的查询结果中。
-
-1. 数据准备
-
-```SQL
-CREATE TABLE event_tb (
-    event STRING,
-    process DOUBLE,
-    event_time TIMESTAMP
-  );
-INSERT INTO event_tb VALUES
-  ('event-0', 20.0, TIMESTAMP '2023-09-20 14:43:13'),
-  ('event-0', 20.0, TIMESTAMP '2023-09-19 11:40:13'),
-  ('event-1', 21.0, TIMESTAMP '2023-09-19 14:30:14'),
-  ('event-1', 22.0, TIMESTAMP '2023-09-20 14:20:15');
-```
-
-2. 数据加工
-
-* 新建SQL脚本“1.时间处理dt”，将准备的数据使用SQL创建dy进行加工
-
-  ![](.topwrite/assets/image_1716280688236.png)
-
-```SQL
-CREATE dynamic TABLE IF NOT EXISTS event_gettime AS
-SELECT    event,
-          process,
-          YEAR(event_time) event_year,
-          MONTH(event_time) event_month,
-          DAY(event_time) event_day,
-          hour(event_time) event_hour,
-          minute(event_time) event_minute
-FROM      event_tb;
-
-REFRESH   dynamic TABLE event_gettime;
-```
-
-* 新建SQL脚本“2.聚合dy”，对上一步加工完的数据进行聚合操作
-
-  * ```SQL
-    CREATE dynamic TABLE IF NOT EXISTS event_group_minute AS
-    SELECT    event,
-              event_hour,
-              event_minute,
-              SUM(process) process_sum
-    FROM      event_gettime
-    GROUP BY  event,
-              event_hour,
-              event_minute;
-
-    refresh dynamic table event_group_minute;
-    ```
-
-3. 构建依赖和调度关系
-
-* 任务一“1.时间处理dt” 配置定时一分钟调度一次
-
-  * ![](.topwrite/assets/image_1716280711741.png)
-
-* 任务二“2.聚合dy” 按照任务一配置定时一分钟调度一次，并且在调度依赖中配置**依赖任务一“1.时间处理dt”**
-
-  * ![](.topwrite/assets/image_1716280739978.png)
-
-* 在数据开发界面每个任务点击提交任务
-
-  * ![](.topwrite/assets/image_1716280770050.png)
-
-4. 查看是否增量刷新
-
-```SQL
---手动插入数据
-INSERT INTO event_tb VALUES
-  ('event-0', 20.0, TIMESTAMP '2024-01-20 14:43:13');
- --查看event_gettime是否是增量刷新和增量刷新了多少条
-SHOW DYNAMIC TABLE REFRESH HISTORY WHERE name='event_gettime';

-# Dynamic Table 支持参数化定义
-
-Dynamic Table 的参数化定义由两部分组成。
-
-* 创建分区动态表时，参数通过 SESSION_CONFIGS()['dt.args.xx'] 进行定义，用于写在 SQL 加工逻辑中，表示查询源表。SESSION_CONFIGS()是系统内置函数`'dt.args.xx'`：DT参数的名称，必须以`dt.arg.`开头，以避免与系统内部字段冲突。表达的含义和传统调度中select * from source_table where pt=${bizdate}，`SESSION_CONFIGS()['dt.args.pt']`等价于`pt=${bizdate}`。SESSION_CONFIGS()['dt.args.xx'] 返回值类型为 String。如果需要其它类型的参数，需要使用 CAST 函数进行转换，例如 `cast(SESSION_CONFIGS()['dt.args.xx'] as int)`。 如下案例：
-
-```sql
---源表
-CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
-
---定义动态表
-CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
-SELECT    col1,
-          nvl(col2, col1),
-          pt
-FROM      source_table
-WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
-```
-
-* 刷新时通过 `refresh dynamic table target_table partition(pt=${bizdate});` 指定分区值，其中 `pt=${bizdate}`。这对应于传统的 `insert overwrite target_table partition(pt=${bizdate})`。
-
-```sql
---上面中定义的动态表分区字段是pt。因此刷新时传入pt=${bizdate}。这里假定bizdate是2024-11-13。刷新时应该使用如下语法
---将2024-11-13传入到创建语句时的SESSION_CONFIGS()['dt.args.pt']中，替换为2024-11-13用于过滤source_table中的数据
-SET dt.args.pt = 2024-11-13;
---刷新时指定pt=2024-11-13表示写入到动态表的2024-11-13分区中
-REFRESH   dynamic TABLE incremental_dt PARTITION (pt = '2024-11-13');
-```
-
-
-
-## 全量刷新与增量刷新
-
-### 全量刷新
-
-全量刷新发生在以下情况：
-
-1. **非分区表**：
-
-   - 如果在非分区表中使用了参数 `SESSION_CONFIGS()['dt.args.event_day']`，系统会根据参数值的变化决定刷新方式。
-   - 如果参数值保持不变，系统将执行**增量刷新**。
-   - 如果参数值发生变化，系统将执行**全量刷新**，因为参数值的变化等同于改变了表的定义。
-
-2. **分区表**：
-
-   * 如果分区已存在，但当前刷新的参数与上一次刷新的参数不相同，则进行一次全量刷新，因为参数值的变化会导致 SQL 加工逻辑发生变化。
-   * 如果分区不存在（即第一次刷新某个分区），则进行一次全量刷新。
-    
-
-```sql
--- 创建源表
-CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
-
--- 创建动态表
-CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
-SELECT    col1,
-          nvl(col2, col1),
-          pt
-FROM      source_table
-WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
-
--- 示例 1：首次设置参数值为 2024-11-13
-SET dt.args.xxx = 1;
-SET dt.args.pt = 2024-11-13;
---刷新为全量刷新
-REFRESH   dynamic TABLE incremental_dt PARTITION (pt = '2024-11-13');
-
--- 示例 2：果第一次刷新某个分区，对应的参数是一个值，如果后面相同分区对应的参数发生了改变了，则相当于dt在这个分区的定义被修改了，所以会重新刷新，如下案例
-SET dt.args.xxx = 2;
-SET dt.args.pt = 2024-11-14;
--- 刷新动态表，指定分区 pt=2024-11-14
--- 系统会执行全量刷新，因为参数值发生了变化
-REFRESH   dynamic TABLE incremental_dt PARTITION (pt = '2024-11-14');
-
-```
-
-### 增量刷新
-
-增量刷新发生在以下情况：
-
-* 非分区表的参数值保持不变。
-* 分区表的参数值保持不变，且分区条件未改变。
-
-**示例代码**：
-
-```SQL
-
--- 创建源表
-CREATE    TABLE source_table (col1 string, col2 string, pt string) PARTITIONED BY (pt);
-
--- 定义动态表
-CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
-SELECT    col1,
-          nvl(col2, col1),
-          pt
-FROM      source_table
-WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
-
--- 示例 1：首次设置参数值为 2024-11-13
-SET dt.args.pt = 2024-11-13;
-
--- 刷新动态表，指定分区 pt=2024-11-13，全量刷新
-REFRESH   dynamic TABLE target_table PARTITION (pt = '2024-11-13');
-
--- 示例 2：参数值和分区值未变化，再次刷新
-SET dt.args.pt = 2024-11-13;
-
--- 刷新动态表，指定分区 pt=2024-11-13
--- 系统会继续执行增量刷新
-REFRESH   dynamic TABLE target_table PARTITION (pt = '2024-11-13');
-```
-
-## 刷新语句
-
-参数化定义的Dynamic Table的刷新行为取决于表是否为分区表。
-
-### **非分区表刷新语法**：
-
-```SQL
-REFRESH DYNAMIC TABLE dt;。
-```
-
-* 非分区表的参数值保持不变，会进行增量刷新。非分区表的参数值发生变化，会进行全量刷新。
-
-### **分区表刷新语法**：
-
-```SQL
-REFRESH DYNAMIC TABLE dt PARTITION partition_spec;
-```
-
-语句刷新分区表时，必须按照表的分区层级顺序指定`partition_spec`。这意味着，如果表按照多个字段进行分区，这些字段需要按照从最高级别到最低级别的顺序被指定。
-* 多级分区，partition\_spec 需要根据分区的层级依次指定。例如，如果表有三级分区(day, hour, min)，必须从高到低依次指定，不能跳过某个分区。指定 day hour 是合法的，低级分区可以忽略，不用全声明。指定 day min 是不合法的，因为它跳过了 hour
-
-  * ```SQL
-    --不合法的
-    set dt.args.day = 1;
-    set dt.args.min = 1;
-    REFRESH   dynamic TABLE incremental_dt PARTITION (DAY = 1, MIN = 1);
-
-    --合法的
-    set dt.args.day = 1;
-     set dt.args.hour = 1;
-    REFRESH   dynamic TABLE incremental_dt PARTITION (DAY = 1, HOUR = 1);
-    ```
-**示例说明**：
-
-假设一个表按照`day`、`hour`和`min`三级进行分区，正确的`partition_spec`指定方式如下：
-
-* **合法指定**：可以指定高层级和部分低层级分区，但不可跳过任何中间层级分区。
-
-```SQL
-set dt.args.day=2024-11-13;
-set dt.args.hour=23;
-REFRESH DYNAMIC TABLE dt PARTITION (day='2024-11-13', hour=23); 
-```
-
-在这个例子中，`day`和`hour`被指定，而`min`分区可以被忽略。
-
-* **不合法指定**：跳过任何中间层级分区的指定是不被允许的。
-
-```SQL
-set dt.args.day=2024-11-13
-set dt.args.hour=30
-REFRESH DYNAMIC TABLE dt PARTITION (day='2024-11-13', min=30); 
-```
-
-## **注意事项**
-
-* **参数与分区一致性**：在执行 Dynamic Table 的刷新操作时，必须确保 SQL 计算逻辑中使用的分区参数值与 REFRESH 语句中指定的分区值保持一致。如果存在不一致，系统将在执行过程中报错。
-
-```SQL
-CREATE dynamic TABLE incremental_dt (col1, col2, pt) PARTITIONED BY (pt) AS
-SELECT    col1,
-          nvl(col2, col1),
-          pt
-FROM      source_table
-WHERE     pt = SESSION_CONFIGS () ['dt.args.pt'];
-
---比如select col1, nvl(col2, col1), pt from source_table where pt = SESSION_CONFIGS()['dt.args.pt'];过滤出来对应的分区字段结果是9.系统将在执行过程中报错，
-set dt.args.event_day = 9;
-
-REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 19);
-
-```
-
-* **并发刷新任务**：在这些命令中，参数值与分区值匹配，因此可以并发执行而不会发生冲突。只要分区之间不存在冲突，系统允许同时执行多个分区的刷新任务。
-
-```SQL
--- 为分区 event_day=19 设置参数并刷新
-set dt.args.event_day = 19;
-
-REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 19);
-
--- 为分区 event_day=20 设置参数并刷新
-set dt.args.event_day = 20;
-
-REFRESH   dynamic TABLE event_gettime_pt PARTITION (event_day = 20);
-```
-
-## 使用案例
-
-* 动态表分区字段和源表中字段一致
-
-```sql
-CREATE TABLE event_tb_pt (
-    event STRING,
-    process DOUBLE,
-    event_time TIMESTAMP
-  );
-INSERT INTO event_tb_pt VALUES
-  ('event-0', 20.0, TIMESTAMP '2024-09-20 14:43:13'),
-  ('event-0', 20.0, TIMESTAMP '2024-09-19 11:40:13'),
- ('event-1', 20.0, TIMESTAMP '2024-09-19 11:40:13');
---创建动态表
-CREATE dynamic table  event_gettime_pt 
-partitioned by(event)
-AS SELECT
-  event,
-  process,
-  YEAR(event_time) event_year,
-  MONTH(event_time) event_month,
-  DAY(event_time) event_day
-FROM event_tb_pt
-where event=SESSION_CONFIGS()['dt.args.event'];
---刷新动态表
-set dt.args.event = event-0;
-REFRESH   dynamic TABLE event_gettime_pt PARTITION (event = 'event-0');
-SELECT *FROM event_gettime_pt;
-```
-
-* 动态表分区字段和源表字段名不一致。过滤条件需要根据 `event` 字段过滤，而动态表的分区字段是 `event_year`。

-## 场景案例
-
-**案例一：将离线任务转换为增量任务**
-
-本节将指导用户如何将原有的离线任务转换为增量任务，以实现更高效的数据处理。以下是一个基于“传统调度”的具体操作步骤，适用于业务逻辑按天对齐和按天调度刷新的场景。
-
-* 步骤 1：参数化原始 SQL。原始 SQL如下
-
-  ```sql
-  with tmp_channel as (
-    select
-      channel_code,
-      channel_name,
-      channel_type,
-      channel_uid
-    from dim.dim_shop_sales_channel_main
-    where pt = '${bizdate}'
-  ), tmp_bac_misc as (
-    select
-      mini_number,
-      bac_no
-    from dim.dim_customer_bac_misc_df
-    where pt = '${bizdate}'
-  ), tmp_fxiaoke as (
-    select
-      case
-        when record_type in ('dealer__c') then nvl(bac_no, account_no)
-        else account_no
-      end as channel_code,
-      id,
-      account_no
-    from ods.ods_account_obj as a
-    left join tmp_bac_misc on a.account_no = tmp_bac_misc.mini_number
-    where pt = '${bizdate}' and account_no is not null
-  --  and is_deleted = 0
-  --  and life_status not in ('invalid', 'ineffective')
-  )
-  insert overwrite table dim.dim_shop_sales_channel_misc partition(pt='${bizdate}')
-  select
-    tmp_channel.channel_code,
-    channel_name,
-    channel_type,
-    channel_uid,
-    id as fxiaoke_id,
-    account_no as fxiaoke_account_no
-  from tmp_channel
-  left join tmp_fxiaoke on tmp_channel.channel_code = tmp_fxiaoke.channel_code ;
-  ```
-
-  首先，需要将原始 SQL 中的所有由调度引擎传入的参数 `${bizdate}` 替换为 `SESSION_CONFIGS()['dt.args.bizdate']`。这一步骤将使得参数值可以通过配置动态传入，而不是硬编码在 SQL 中。
-
-  **原始 SQL 参数替换**:
-  将所有 `${bizdate}` 替换为 `SESSION_CONFIGS()['dt.args.bizdate']`：
-
-  ```sql
-  create dynamic table im.dim_shop_sales_channel_misc
-  partitioned by(pt)
-  with tmp_channel as (
-    select
-      channel_code,
-      channel_name,
-      channel_type,
-      channel_uidfrom dim.dim_shop_sales_channel_main
-      where pt = SESSION_CONFIGS()['dt.args.bizdate']
-  ), tmp_bac_misc as (
-    select
-      mini_number,
-      bac_nofrom dim.dim_customer_bac_misc_df
-      where pt = SESSION_CONFIGS()['dt.args.bizdate']
-  ), tmp_fxiaoke as (
-    select
-      case
-        when record_type in ('dealer__c') then nvl(bac_no, account_no)
-        else account_noend as channel_code,
-      id,
-      account_nofrom ods.ods_account_obj as aleft join tmp_bac_misc on a.account_no = tmp_bac_misc.mini_number
-      where pt = SESSION_CONFIGS()['dt.args.bizdate'] and account_no is not null
-  )
-  select
-    tmp_channel.channel_code,
-    channel_name,
-    channel_type,
-    channel_uid,
-    id as fxiaoke_id,
-    account_no as fxiaoke_account_no,
-    pt
-  from tmp_channel
-  left join tmp_fxiaoke on tmp_channel.channel_code = tmp_fxiaoke.channel_code
-  ;
-  ```
-
-* 步骤 2：调度刷新命令
-  在每次调度时，需要将参数 `dt.args.bizdate` 设置为具体的日期值，并执行刷新命令。
-
-  调度刷新命令示例
-
-  ```sql
-  SET dt.args.bizdate=20241130; -- ${bizdate}由Studio每次替换为具体的值
-  REFRESH DYNAMIC TABLE DT PARTITION (pt ='20241130');
-  ```
-
-**案例二：增量任务数据补数**
-
-在某些情况下，用户可能需要向已有的分区中补充数据。
-
-* 方法 1：向源表补充数据，用户可以直接向源表中补充数据。这些补充的数据将通过相应的 REFRESH 任务自动反映到 Dynamic Table（DT）中。
-
-  操作步骤
-
-  1. 直接向源表插入或更新数据。
-  2. 执行 REFRESH 任务，以将更改同步到 DT 中。
-* 方法 2：使用 DML 语句直接向 DT 补充数据，用户也可以使用 DML 语句直接向 DT 的特定分区中插入数据。
-  操作步骤
-  1. 使用 DML 语句向 DT 的特定分区插入数据。
-  2. 请注意，直接修改 DT 将导致下一次该分区的全量刷新。如果用户不希望出现全量刷新的结果，应避免调度该分区的 REFRESH 任务。
-     示例代码
-  ```sql
-  INSERT INTO DYNAMIC TABLE incremental_dt VALUES (...);
-  ```
-
-**注意事项**
-
-* 直接向 DT 插入的数据将参与 DT 的下游计算。如果下游的老分区不需要这些数据，请不要调度涉及这些数据的分区的 REFRESH 任务。
-* 其他未受影响的分区仍然可以进行增量刷新。
-
-**案例三：在不同 VC 中执行增量任务**
-
-对于参数化声明的分区化 DT，不同分区的刷新任务可以同时执行。用户可以根据需要将不同的 REFRESH 任务分配到不同的虚拟集群（VC）中执行。
-**操作步骤**：
-1. 根据时效性要求和资源需求，将不同的 REFRESH 任务分配到不同的 VC 中。
-2. 例如，对于时效性要求较高的新分区，可以将其 REFRESH 任务放在资源较多的大 VC 中执行。
-3. 对于其他老分区的补充任务，可以将其 REFRESH 任务放在资源较少的小 VC 中执行。

-# 动态表简介
->【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请联系我们的技术支持同学协助处理。
-
-## 什么是动态表
-
-动态表（Dynamic Table）是云器Lakehouse的数据对象。创建时与表的区别是通过定义查询语句动态生成数据，刷新时自动获取的Base Table的增量数据，采用增量算法来进行计算，这样做的优势是大幅提升数据处理效率，尤其适用于处理大规模数据。
-## Dynamic Table捕获源表变化的时效性
-
-Dynamic Table根据源表对象的元数据修改提交时间来感知变化数据，源表发生变化并且完成元数据提交的变化可以被捕获，源表变化可能存在以下情况影响变化数据的时效性：
-
-* DML方式修改数据：源表发生DML操作，DML任务成功结束后，源表变化数据可被Dynamic Table访问；
-* 批量导入（Bulkload）：源表有批量任务导入，在批量导入任务成功结束后，源表的变化数据可被Dynamic Table访问；
-* 流式导入：源表通过Ingestion Service流式API写入数据，默认1Min提交变化，提交后源表的变化数据即可被Dynamic Table访问。注：对于流式写入的源表本身进行SQL查询时是实时可见，这里仅约束了基于该表的增量变化被Dynamic Table可见的时效。
-
-
-## 动态表应用场景
-
-### 不适用于增量场景
-1. 查询操作里存在大量数据排序需求，例如使用了 Orderby 子句。
-2. Window 函数需要对数据进行排序（RowNumber=1 的情况除外），并且增量数据中包含多个数据量特别大的 Partition。
-3. 数据缺乏良好的聚集性，无法通过 Joinkey、Aggregat key、Window partition key 等清晰地将冷数据和热数据区分开来。
-4. Aggregat key中目前支持的类型有CHAR、VARCHAR、STRING、TINYINT、SMALLINT、INT、BIGINT、DECIMAL、BOOLEAN、DATE如果有其他类型则不支持
-
-### 面向实时加工场景
-
-在实时数据加工场景中，数据以持续且快速的方式流入系统。传统的数据处理方法，如完全重载（Full Reload）或全量刷新（Full Refresh），在性能和资源消耗方面可能不够高效，特别是在处理大规模数据流时。动态表采用增量计算方法，仅处理自上次更新以来变化的数据，从而显著减少了计算资源的消耗。
-
-**动态表的优势**：
-
-* **实时性**：能够迅速将新数据变更反映到数据仓库中，保持数据的高新鲜度。
-* **成本效益**：通过设置合理的刷新间隔，可以平衡性能与成本，实现资源的最优利用。
-* **资源弹性**：Lakehouse的资源可以轻松实现弹性扩展，尤其在处理峰值数据流入时更具优势。
-* **按需计算**：未来Lakehouse将实现按需启动计算资源，即仅在有数据需要计算时才会启动相应资源，进一步提高效率和降低成本。
-
-**应用实例**：
-
-**背景**： 一家电子商务公司希望实时分析其销售数据，以便快速做出库存和定价决策。数据以高速率持续流入系统，需要一种高效的数据处理方法。
-
-**挑战**：
-
-* 传统的全量数据处理方法在性能和资源消耗方面效率低下，尤其是在高峰时段。
-* 需要一种能够快速响应数据变更并保持数据新鲜的处理机制。
-
-**解决方案**：
-
-* 引入动态表，采用增量计算方法，仅处理自上次更新以来变化的数据。
-
-**动态表的优势**：
-
-1. **实时性**： 动态表能够迅速捕捉并反映数据变更，确保决策基于最新的销售数据。
-
-2. **成本效益**：通过动态表，公司可以根据实际需求设置合理的数据刷新间隔，避免了不必要的计算资源浪费。
-
-3. **资源弹性**：在促销活动或节假日等流量高峰时段，Lakehouse的资源可以按需扩展，以应对数据流入的峰值，而不必长期维持高额的资源配置。
-
-4. **按需计算**：未来，Lakehouse的按需计算功能将进一步提高效率，仅在有数据需要计算时才启动资源，从而降低成本。
-
-### 数据新鲜度要求较高的固定维度分析查询场景
-
-在固定维度分析查询场景中，我们追求的是能够提供近乎实时的分析结果。传统的视图查询可以实现这一点，但如果涉及大量数据转换，则可能会导致查询速度变慢。为了解决这个问题，我们可以将转换后的结果进行物化，这样在查询时就可以直接返回这些结果，从而提高查询速度。物化结果可以采用传统的表格或者dynamic table。
-
-使用传统的表可以提供最高的性能，因为它们在查询时只返回预先转换好的数据。但这种方法的缺点是，需要定期评估数据转换的时间，并通过调度进行全量计算，这通常会占用较长的时间。
-
-dynamic table结合了增量计算的优势。通过仅更新自上次加载以来发生变化的记录，dynamic table不仅减少了每次构建的时间，通过缩短时间间隔还保持了数据的最新性。
-
-### 注意事项
-
-* 在处理源端大量变化数据时，计算任务可能接近全量计算的负载。尽管增量计算在效率上具有明显优势，但如果您设置的刷新间隔过短，可能会导致任务积压。这是因为每次刷新操作本身需要一定的时间来完成，如果这个时间超过了您设置的刷新间隔，将会导致后续刷新任务的排队等待。
-  * **建议**：
-    * **合理设置刷新间隔**：根据数据变更的频率和任务的刷新耗时，合理设置刷新间隔，以避免刷新操作的积压。
-    * **监控和调整**：持续监控数据变更模式和系统性能，根据实际情况调整刷新间隔，以实现效率和资源的最优化利用。
-* 在编写算子时参考算子是如何增量刷新中的注意事项来优化增量刷新任务
-### 不适合场景
-1. 涉及大量 Outer Join 操作，且 Outer Join 右表数据频繁变动。
-2. 是否存在大量数据排序操作（如使用 Order by）。
-3. Window 操作需对数据排序（RowNumber=1 情况除外），同时增量数据包含多个数据量极为庞大的 Partition。
-4. 数据是否具有良好的聚集特性，例如能否通过 Join key、Aggregate key 或 Window partition key 明确区分冷数据与热数据。
-
-## 动态表工作原理概述

-## Lakehouse Dynamic Table 刷新机制
-
-Lakehouse 目前使用调度机制来更新 Dynamic Table。支持以下几种调度模式：
-
-1. **在** **DDL** **语句中定义调度属性**
-2. **在 Lakehouse Studio 中定义调度**
-3. **使用第三方调度引擎提交 Refresh 作业**
-
-|                          | 使用方式                                                                                                    | 优点                                                        | 缺点                                                                                    |
-| ------------------------ | ------------------------------------------------------------------------------------------------------- | --------------------------------------------------------- | ------------------------------------------------------------------------------------- |
-| DDL语句中定义调度属性             | 在refreshOption中定义刷新间隔，具体使用方式[参考动态表创建文档](<create-dynamic-table.md>)。目前限制刷新间隔一分钟。 | 简单易用，可以快速设置刷新选项。不依赖任何第三方工具。                               | 当前Lakehouse不支持在 Dynamic Table 上定义严格的上下游依赖关系。在 DDL 定义中依赖时间调度。可以通过时间间隔的方式先保证上游刷新完成再调度下游 |
-| 在 Lakehouse Studio 中定义调度 | 可以在 Lakehouse Studio 中通过可视化界面配置调度，具体配置方式可以参考[任务开发调度文档](taskdevelop.md)。目前限制刷新间隔一分钟。                     | 可视化配置，用户友好。支持调度依赖配置，确保上游刷新完成后再刷新下游。支持单节点运行监控，如失败告警、超时告警等。 |                                                                                       |
-| 使用第三方调度引擎提交 Refresh 作业   | 通过下载 Lakehouse 客户端命令，使用 cron 表达式定时提交 Refresh 任务。或者通过 Java Jdbc 接口自定义提交 Refresh 命令。                      | 您可以更灵活地控制作业的提交和配置调度信息，时间间隔没有限制                            | 需要依赖第三方调度。引入第三方调度系统                                                                   |
-
-## 动态表和物化视图、普通视图的比较
-
-从Lakehouse的实现机制上来看，动态表是基于传统的物化视图来演进的，虽然两者有一些共性，但是定位上存在很大区别
-
-|       | 物化视图                                        | 动态表                         | 普通视图                                              |
-| ----- | ------------------------------------------- | --------------------------- | ------------------------------------------------- |
-| 定义    | 一种预计算并存储查询结果的特殊视图                           | 专注于数据加工的高效工具                | 一种虚拟表，不存储数据，只保存查询定义                               |
-| 性能优化  | 显著提升查询效率，通过预存结果减少重复计算。其他 SQL可以利用该物化结果进行查询改写 | 虽然也可以提高查询效率，但是查询优化器不会进行查询改写 | 性能取决于底层数据表的查询效率,查询是计算逻辑每次重新计算                     |
-| 数据时效性 | 要求数据即时更新，以确保查询改写的准确性                        | 注重数据加工灵活性，可调整数据滞后性          | 数据新鲜度每次都是最新的                                      |
-| 更新机制  | 采用定时刷新机制，保持数据最新                             | 根据业务定义调整，不强制实时更新            | 不存储数据无需更新                                         |
-| 查询优化  | 优化器自动识别并使用预存结果                              | 不依赖于查询优化器的自动重写              |                                                   |
-| 使用场景  | 适合于预计算并复用查询结果的场景                            | 适合数据加工，可能数据不是最新的            | 适合于查询复杂度不高不涉及大量加工,如果涉及大数据量和很多复杂算子，查询很慢，因为每次都是重新计算 |
-| 运维    | 无复杂运维场景                                     | 动态表还支持了复杂的加列，版本回滚等功能        | 无复杂运维场景                                           |

-## 动态表刷新监控
-
-### 通过 SQL 命令查看刷新历史
-
-您目前可以利用 SQL 命令来监控动态表的刷新历史。尽管该命令可能尚未全面上线，但您已经可以通过以下 SQL 语句来获取所有动态表的刷新情况概览：
-
-```SQL
-SHOW DYNAMIC TABLE REFRESH HISTORY [WHERE <condition>];
-```
-
-**过滤刷新历史**
-
-您可以使用 `WHERE` 子句来根据特定字段过滤信息，例如，要查看名为 `my_dy` 的动态表的刷新历史，可以使用以下命令：
-
-```SQL
-SHOW DYNAMIC TABLE REFRESH HISTORY WHERE name='my_dy';
-```
-
-| 字段名称             | 含义                                                                    |

-
-* 您也可以通过job profile的输入记录来判断是否是增量读取数据
-
-## 动态表的成本
-
-#### 计算成本
-
-动态表的刷新操作依赖于计算资源（Virtual Cluster）来执行，包括：
-
-* **定时刷新**：根据设定的时间间隔自动执行刷新。
-* **手动刷新**：用户根据需要手动触发刷新。
-
-这些刷新操作均会消耗计算资源。
-
-#### 存储成本
-
-动态表同样需要存储空间来保存其具体化结果。与常规表一样，动态表支持：
-
-* **Time Travel**：允许用户访问过去7天内的任何时间点的数据。
-* **Time Travel 保留期限**：默认设置为7天，超过此期限后，数据将无法通过Time Travel访问，并且会被物理删除。
-
-
-#### 刷新调度设置周期
-
-**刷新速度影响因素**
-
-增量刷新的速度主要取决于两个因素：
-
-1. **源数据的变更量**：刷新操作需要处理的数据量越大，所需的时间就越长。
-2. **固定开销**：无论数据变更量大小，每次刷新都会产生的一些基本开销。
-
-**商业价值与刷新频率**
-
-* 如果数据新鲜度对您的业务价值不是至关重要，可以考虑降低刷新频率。这种策略可以减少因频繁刷新带来的计算开销。
-* 采用增量计算模式可以提高单次刷新的速度，因为它只处理自上次刷新以来发生变化的数据。
-
-**刷新成本与频率的平衡**
-
-* 刷新成本会随着刷新频率的增加而上升。因此，您需要在数据新鲜度所带来的商业价值和由此产生的计算成本之间做出权衡。
-* 高频率的刷新操作虽然可以保持数据的实时更新，但累积的计算成本也会随之增加。
-
-**建议**
-
-* 评估您的业务需求，确定数据新鲜度对您业务的具体价值。
-* 根据业务价值来设定合理的刷新频率，以优化成本效益。
-* 利用增量计算模式来提高刷新效率，减少不必要的计算开销。
-
-## 动态表限制
-
-* 增量刷新限制：不支持非确定性函数，比如random、current\_timestmap、current_date等
-* 不支持直接修改动态表数据，比如执行update、delete、truncate数据
-
-# 使用动态表加工案例
-
-## 使用动态表加工Lakehouse提供的样例数据
-
-Lakehouse 提供了一个名为 `ecommerce_events_multicategorystore_live` 的动态公共数据集，该数据集位于 `clickzetta_sample_data.clickzetta_sample_data.ecommerce_events_history` 路径下。这个数据集是实时更新的，并且可以被直接查询。
-
-实时数据集可用性：目前，`ecommerce_events_multicategorystore_live` 实时写入的公共数据集只在阿里云的上海区域提供。如果您的账户或服务不在该区域，您将无法查询此公共数据集。
-
-1. **编写SQL脚本使用DDL定义调度加工数据**
-
-```SQL
-CREATE  DYNAMIC TABLE event_type_count
-REFRESH interval 1 minute vcluster default
-as
-SELECT event_type, COUNT(*) AS events_count
-FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live
-GROUP BY event_type;
---初始化DYNAMIC TABLE数据
-REFRESH DYNAMIC TABLE event_type_count;
-```
-
-2. 查看动态表刷新
-
-**使用命令查看动态表刷新**
-
-```SQL
-SHOW DYNAMIC TABLE REFRESH HISTORY WHERE name='event_type_count';
-```
-
-**在作业历史中查看dynamic table刷新历史**
-
-![](.topwrite/assets/image_1716280651911.png)
-
-点进详情中可以查看输入记录可以看到获取了增量多少条，诊断中可以查看增量执行SQL的计划
-
-![](.topwrite/assets/image_1716280668286.png)
-
-3. **在作业历史中看到增量刷新有数据后，可以查看数据变化**
-
-```SQL
-SELECT    *   FROM      event_type_count;
-+-------------+--------------+
-| event_type  | events_count |
-+-------------+--------------+
-| view        | 91634700     |
-| purchase    | 91630921     |
-| add_to_cart | 91622270     |
-+-------------+--------------+
---增量刷新完成后查看数据
-SELECT    *
-FROM      event_type_count;
-+-------------+--------------+
-| event_type  | events_count |
-+-------------+--------------+
-| purchase    | 91633135     |
-| add_to_cart | 91624515     |
-| view        | 91636913     |
-+-------------+--------------+
-```
-
-## 使用STUDIO刷新调度动态表刷新任务
-
-在本次演示中，我们将通过以下步骤模拟增量数据的插入，并展示增量计算的效果：
-
-* **模拟增量数据插入**：使用 `INSERT INTO` 语句将模拟数据插入到指定表中，以此来模拟实际业务场景中的增量数据更新。
-* **利用 Studio 调度刷新**：随后，我们将利用 Lakehouse Studio 的调度功能来触发和执行增量数据的刷新任务。
-* **演示增量计算效果**：通过上述步骤，我们旨在展示增量计算如何高效地处理新插入的数据，并将更新反映在最终的查询结果中。
-
-1. 数据准备
-
-```SQL
-CREATE TABLE event_tb (
-    event STRING,
-    process DOUBLE,
-    event_time TIMESTAMP
-  );
-INSERT INTO event_tb VALUES
-  ('event-0', 20.0, TIMESTAMP '2023-09-20 14:43:13'),
-  ('event-0', 20.0, TIMESTAMP '2023-09-19 11:40:13'),
-  ('event-1', 21.0, TIMESTAMP '2023-09-19 14:30:14'),
-  ('event-1', 22.0, TIMESTAMP '2023-09-20 14:20:15');
-```
-
-2. 数据加工
-
-* 新建SQL脚本“1.时间处理dt”，将准备的数据使用SQL创建dy进行加工
-
-  ![](.topwrite/assets/image_1716280688236.png)
-
-```SQL
-CREATE dynamic TABLE IF NOT EXISTS event_gettime AS
-SELECT    event,
-          process,
-          YEAR(event_time) event_year,
-          MONTH(event_time) event_month,
-          DAY(event_time) event_day,
-          hour(event_time) event_hour,
-          minute(event_time) event_minute
-FROM      event_tb;
-
-REFRESH   dynamic TABLE event_gettime;
-```
-
-* 新建SQL脚本“2.聚合dy”，对上一步加工完的数据进行聚合操作
-
-  * ```SQL
-    CREATE dynamic TABLE IF NOT EXISTS event_group_minute AS
-    SELECT    event,
-              event_hour,
-              event_minute,
-              SUM(process) process_sum
-    FROM      event_gettime
-    GROUP BY  event,
-              event_hour,
-              event_minute;
-
-    refresh dynamic table event_group_minute;
-    ```
-
-3. 构建依赖和调度关系
-
-* 任务一“1.时间处理dy” 配置定时一分钟调度一次
-
-  * ![](.topwrite/assets/image_1716280711741.png)
-
-* 任务二“2.聚合dy” 按照任务一配置定时一分钟调度一次并且在调度依赖中配置**依赖任务一“1.时间处理dy**”
-
-  * ![](.topwrite/assets/image_1716280739978.png)
-
-* 在数据开发界面每个任务点击提交任务
-
-  * ![](.topwrite/assets/image_1716280770050.png)
-
-4. 查看是否增量刷新
-
-```SQL
---手动插入数据
-INSERT INTO event_tb VALUES
-  ('event-0', 20.0, TIMESTAMP '2024-01-20 14:43:13');
- --查看event_gettime是否是增量刷新和增量刷新了多少条
-SHOW DYNAMIC TABLE REFRESH HISTORY WHERE name='event_gettime';
-+----------------+-------------+---------------+-----------------+-------------------------+-------------------------+----------------------+---------+-----------------+------------------+--------------+---------------+-------------------------------------------------------------------+------------------------------------------+-------------------+-------------------------------+

-```
-
-## 使用动态表节点加工任务
-使用方式参考[动态表任务](<dynamic_table_task.md>)
-
-
-## **约束限制**
-* 除了列出的 current_date非确定性函数，其他非确定性函数不支持。如果使用非确定性函数创建则报错
-* 建议使用GP型集群来刷新动态表。原因：动态表刷新过程中会根据内置策略自动执行小文件合并操作，而AP型集群不支持此功能。

-# 动态表任务
-
->【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请在页面申请或者联系我们的技术支持同学协助处理。
-
-
-Web-IDE 提供了支持协作开发的向导式动态表任务模板，提高动态表任务的开发效率，同时支持与任务运维、监控告警功能打通，增强面向生产的运维监控能力。
-
-Web-IDE 中动态表的开发过程，是通过可视化的向导方式辅助用户编写创建动态表所需的必要内容。例如：动态表所在的schema、动态表名称、刷新周期、动态表查询逻辑等。开发动态表脚本完成后，执行任务"提交"时系统会根据脚本内容在目标位置创建动态表、动态表的刷新策略配置进行自动化调度，从而实现动态表任务的部署上线。
-
-* 第一步：新建动态表任务
-
-您可以在Studio的IDE开发环境中，通过新建任务的方式添加"动态表"类型的任务。
-
-![](.topwrite/assets/image_1722413586664.png)
-
-新建时，为任务指定名称并选择保存位置。
-
-![](.topwrite/assets/image_1722413608121.png =347)
-
-* 第二步：为动态表命名并编写动态表的SELECT查询语句
-
-首先，填写动态表在提交后将要保存的schema位置以及动态表名称
-
-![](.topwrite/assets/image_1722413623690.png)
-
-其次，在SQL代码区域编写和测试动态表的查询语句。
-
-在 SQL 代码区编写处理转换的 SELECT 语句，设置运行 SQL 的集群名称（当动态表部署运行时，将默认使用该集群运行刷新任务），同时可以通过运行按钮测试运行 SELECT 语句以确保处理逻辑的正确性。
-
-![](.topwrite/assets/image_1722413647339.png)
-
-最后，通过Explain按钮校验查询语句的语法正确性并保存动态表的模型定义
-
-点击按钮检查 SELECT 查询语法的正确性，检查字段名称及数据类型是否符合预期。确认正确后点击弹出窗口的"确定并继续"按钮，系统将保存动态表的定义并退出SQL代码编辑状态。
-
-![](.topwrite/assets/image_1722413661168.png)
-
-* 第三步：修改和调整动态表配置并提交部署
-
-在完成动态表SQL代码开发并退出SQL编辑模式后，您将看到包括动态表基本信息、运行参数、SQL代码、动态表字段、动态表分区及分桶相关的默认配置。
-
-![](.topwrite/assets/image_1722413674413.png)

-# Studio动态表任务与动态表对象的关系
-Studio在开发模块提供了名为"动态表"的任务类型，借助该任务类型提供对动态表任务的开发、运维及监控告警功能支持。在"开发"模块提交动态表任务时，系统将根据代码定义同步创建Lakehouse动态表对象，在"运维"模块下线动态表任务时，系统将自动删除Lakehouse动态表对象。
-注意：在 Studio 开发模块使用动态表任务创建动态表时，系统会检查目标位置是否已经存在 Lakehouse 动态表对象，并提示同名对象存在导致无法创建。此时可修改新建动态表任务名称或在手工删除先前存在的Lakehouse动态表对象后再创建Studio动态表任务。
-
-# 约束与限制
-Studio监控告警模块不支持对直接使用CREATE DYNAMIC TABLE语句创建的动态表进行告警配置。如需使用Studio监控告警对动态表创建告警规则，请通过Web IDE开发模块使用"动态表"任务创建并提交。

-# 动态表（Dynamic Table）
-
->**【预览发布】本功能当前处于受邀预览阶段。如需试用，请通过官网联系方式联系云器科技。**
-
-动态表（Dynamic Table）是云器 Lakehouse 解决方案中的一项创新特性，为用户提供了一种灵活且高效的数据处理与存储方法。与传统静态表相比，动态表不直接存储数据，而是通过定义的查询语句动态生成数据。这种方式在处理大规模数据集和实现数据实时更新方面展现出显著的优势。
-
-## 动态表的核心特性
-
-1.  **查询结果即表**：动态表基于定义的查询语句动态生成数据集，每次查询都可能产生一个全新的数据集，即动态表的内容。
-2. **增量刷新机制**：动态表支持增量刷新，仅在底层数据源发生变化时触发查询语句的执行和内容的更新，大幅提升数据处理效率，尤其适用于处理大规模数据。
-3. **操作限制**：由于数据由查询生成，动态表不支持传统的`UPDATE`、`DELETE`、`INSERT`等直接数据操作，以确保数据的一致性和准确性。
-
-## 动态表的应用场景
-
-*   **数据仓库**：动态表可用于存储经过处理和转换的数据，便于后续的数据分析和报告生成。
-*   **实时数据应用**：对于需要实时数据更新的应用场景，动态表能够提供快速的数据刷新能力，保持数据的时效性。
-*   **数据ETL过程**：在数据提取、转换和加载（ETL）过程中，动态表可作为中间存储，保存转换后的数据集。
-
-## Materialized View和Dynamic Table区别
-
-从 Lakehouse 的实现机制上来看，动态表是基于传统的物化视图演进而来。虽然两者有一些共性，但在定位上存在很大区别。
-
-**物化视图：性能优化利器**
-物化视图是一种预计算并存储查询结果的特殊视图，能够显著提升查询效率。与传统视图不同，物化视图将计算结果保存在类似表的结构中，使得后续相似查询能够被优化器自动识别并直接使用预存结果，从而减少重复计算，加快查询速度。
-
-**动态表：数据加工的高效工具**
-动态表专注于数据加工，虽然也能提升查询性能，但并不依赖于查询优化器的自动重写。物化视图只有保持数据是最新的才能进行查询改写，而动态表面向加工场景，其数据可能并不是最新的。
-
-**传统物化视图在某些产品中具有以下限制，目前 Lakehouse 没有这些限制**：
-
-1.  只能基于单个基表。物化视图不能基于复杂查询（即具有联接或嵌套视图的查询）。
-
-2.  物化视图不一定是增量刷新，不同系统的实现方式各异。少量系统为了节省计算资源、加快加工速度，在部分算子中实现了增量计算。
-
-**动态表的先进特性**：
-
-1.  **增量识别与优化**：支持大数据环境下的文件粒度增量识别，实现实时增量读取和计算优化，以及写入优化。
-2.  **智能决策**：通过基于成本的优化器（Cost-Based Optimizer）智能选择全量、增量或部分增量计算，以适应不同查询需求。
-3.  **实时任务运维**：提供数据版本管理、回退和重跑等机制，为实时任务的运维提供全面支持。
-
-**数据时效性考量**：
-
-* 物化视图要求数据的即时更新，以确保查询改写的准确性。在基表数据变更时，Lakehouse 采用定时刷新机制，确保物化视图的数据始终保持最新。
-* 动态表则更注重数据加工的灵活性，根据业务定义来调整数据的滞后性，而不强制要求数据必须实时更新。
-
-## 动态表管理操作指南
-
-*   **创建动态表**：用户可以通过特定的语法定义新的动态表，并指定用于数据转换的 SQL 查询语句。具体语法和操作步骤详见 [创建动态表](create-dynamic-table.md) 文档。
-*   **删除动态表**：若动态表不再需要，可使用 `DROP TABLE` 命令将其删除。执行删除操作前，请确保数据已备份或确认不再需要，因为该操作会移除动态表的定义及其数据。具体语法和操作步骤详见 [删除Dynamic Table](drop-dynamic-table.md) 文档。
-*   **查看动态表刷新历史**：通过 `SHOW DYNAMIC TABLE REFRESH HISTORY` 命令查看指定动态表的刷新历史，可监控刷新作业的执行状态（成功与否）、运行时长、增量/全量刷新模式、处理的记录数量等信息。
-
-## 数据加工与增量计算
-
-动态表在数据加工中发挥着重要作用。通过定义查询语句，用户能够实现数据的提取、转换和加载（ETL）。同时，动态表支持增量计算，仅在数据源发生变化时触发数据更新，有效减少数据处理的时间和资源消耗。有关动态表的增量计算和数据加工的详细信息，请参阅 [数据加工与增量计算](dynamic_table_summary.md) 文档。

-sql = st.text_area('在这里输入您的 SQL 查询语句')
-
-# 执行查询并展示结果。
-if st.button('运行查询') and sql:
-    result = conn.query(sql)
-    st.dataframe(result)
-```
-
-### 运行应用
-
-使用以下命令运行应用：
-
-```bash
-streamlit run demo.py
-```
-
-Streamlit 会自动打开本地浏览器，访问 <http://localhost:8501>。您也可以手动在浏览器中输入该地址。
-
-### 示例 SQL 查询
-
-以下是一个示例 SQL 查询，用于从 ClickZetta Lakehouse 中获取最近 24 小时内的购买事件数据：
-
-```sql
-SELECT
-  brand,
-  COUNT(DISTINCT user_id) AS unique_user_count,
-  SUM(price) AS sum_price
-FROM
-  clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live
-WHERE
-  event_time >= (NOW() - INTERVAL '24' HOUR)
-  AND event_type = 'purchase'
-GROUP BY
-  brand
-ORDER BY
-  sum_price DESC
-LIMIT 10;
-```
-
-![Streamlit 应用运行效果截图](streamlit-demo.png)
-
-## 进阶示例
-
-### 添加图表展示
-
-为了更好地展示数据，您可以使用 Streamlit 的 `st.plotly_chart` 函数，将查询结果以图表形式展示。首先，安装 `pandas` 和 `plotly` 库：
-
-```bash
-pip install pandas plotly
-```
-
-然后，在 `demo.py` 中添加以下代码：
-
-```python
-import pandas as pd
-import plotly.express as px
-
-# ...
-
-if st.button('生成图表') and sql:
-    result = conn.query(sql)
-    df = pd.DataFrame(result)
-
-    fig = px.bar(df, x='brand', y='sum_price', title='各品牌销售额')
-    st.plotly_chart(fig)
-```

-# Superset ClickZetta adapter 使用指南
-
-## Superset 简介
-
-Superset 是 Airbnb 开源的 BI 数据分析与可视化平台，原名 Caravel 和 Panoramix。该工具的主要特点包括自助分析、自定义仪表盘、分析结果可视化（导出）以及用户/角色权限控制。Superset 还集成了一个 SQL 编辑器，允许用户进行 SQL 编辑和查询。最初，Superset 主要用于支持 Druid 的可视化分析，但后来发展为支持多种关系数据库和大数据计算框架，如 MySQL、Oracle、PostgreSQL、Presto、SQLite、Redshift、Impala、SparkSQL、Greenplum 和 MSSQL。Superset 基于 Python 框架，集成了 Flask、D3、Pandas 和 SQLAlchemy 等技术。
-
-## Superset ClickZetta 适配器
-
-`clickzetta-sqlalchemy` 是一个为 SQLAlchemy 提供 ClickZetta Lakehouse 的 dialect 适配器，使得使用 SQLAlchemy 接口编写的代码或上层应用可以轻松连接到 ClickZetta Lakehouse。Superset 支持类 SQLAlchemy 规范的 URL 配置数据源链接，因此，在 Superset 中连接 ClickZetta 数据库只需配置相应的 URL 即可。
-
-## 安装与配置
-

-   ```shell
-   # 安装与镜像相同的 Superset 版本
-   pip install -r https://raw.githubusercontent.com/clickzetta/awesome-clickzetta/main/superset/requirements.txt
-
-   # 安装更高版本的 Superset
-   pip install 'apache-superset>=2.1'
-   ```
-
-3. 初始化 Superset：
-   ```shell
-   export FLASK_APP=superset
-
-   superset db upgrade
-
-   # 创建管理员用户
-   superset fab create-admin
-
-   superset init
-
-   # 启动服务，绑定在 localhost 的 8088 端口。如需远程访问，可添加 --host 0.0.0.0
-   superset run -p 8088 --with-threads --reload --debugger
-   ```
-
-## 使用方法
-
-### 登录 Superset
-
-* 如果您使用的是镜像，默认用户名为 `admin`，密码为 `clickzetta`。
-* 如果您是本地安装，请使用在安装步骤 `superset fab create-admin` 中填写的用户名和密码。
-
-### 连接 ClickZetta 数据库
-
-1. 点击右上角的 Settings，然后选择 Database Connections，跳转到 Superset 的创建数据库页面。
-2. 点击右上角的 Database，选择 Other 作为数据库类型。
-3. 填写数据库名称和 ClickZetta Lakehouse 的服务 URL。
-4. 点击 TESTING CONNECTION 按钮测试连接是否成功。
-5. 如果测试通过，点击下方的 CONNECT 按钮完成数据库连接。
-
-### ClickZetta URL 格式
-
-ClickZetta URL 的格式如下：
-
-```
-clickzetta://username:password@instance.service/workspace?vcluster=vcluster
-```
-
-其中各部分含义如下：
-
-* username：用户名
-* password：密码
-* instance：实例名称
-* service：服务域名
-* workspace：空间名称
-* vcluster：资源名称
-
-service 支持指定端口。如果不需要指定端口，可以直接使用域名，例如：
-
-```
-# 指定端口

-# 概述
->**【预览发布】本功能当前处于公开预览发布阶段。**
-
-External Catalog 是 Lakehouse 中的一个安全对象，它映射了外部数据系统中的数据库，使得用户可以在 Lakehouse 中对该数据系统执行只读查询。通过 External Catalog，用户可以利用 Lakehouse 的查询能力访问和分析存储在外部数据库中的数据。
-
-# External Catalog使用场景
-* **统一元数据管理**：将多个数据源的元数据统一管理，简化数据治理。
-* **数据联邦查询**：使用 External Catalog，用户可以在不同的数据源之间进行联合查询，如同它们是同一个数据库内的数据一样。通过联邦查询，用户能够实时访问和分析存储在外部系统中的数据，无需等待数据同步。
-* **数据导入**：将分散在不同数据源的数据导入 Lakehouse，构建统一的数据湖，便于进行大数据分析和机器学习。将历史数据或不常访问的数据保留在外部存储中，通过 External Catalog 导入到 Lakehouse，优化数据仓库的存储和性能。
-
-# 使用 External Catalog
-
-1. **创建连接**：首先，需要在 Catalog Connection 中创建一个连接（connection），这个连接是一个安全对象，它指定了用于访问外部数据库系统的路径和认证信息。
-2. **创建外部目录**：使用已创建的连接，可以创建一个外部目录（External Catalog）。这个目录在 Lakehouse 中作为安全对象存在，镜像了外部数据系统中的数据库结构。
-3. **执行查询**：一旦外部目录被创建，用户就可以在Lakehouse中编写 SQL 查询。
-
-# 支持的数据源
-
-Lakehouse 通过多源数据目录（Multi-Catalog）功能，
-- 支持了[Apache Hive连接访问](<create-hive-catalog.md>)
-- 支持External Iceberg Rest Catalog,具体参考[利用 External Catalog 访问 Snowflake OpenCatalog 的 Iceberg 表](<Query_SnowflakeOpenCatalog_Icebergtable.md>)
-- 支持访问Databricks,具体参考[Databricks-云器Lakehouse 跨平台数据联邦最佳实践指南](<databricks_yunqi_integration_guide_v2.md>)
-
-
-# EXTERNAL CATALOG相关使用语法
-- 创建External Catalog
-[参考CREATE EXTERNAL CATALOG](<create-external-catalog.md>)
-- 列出 Catalog
-[参考SHOW CATALOG](<show-catalog.md>)
-- 查看Catalog下的SCHEMA
-参考[查看EXTERNAL CATALOG下的SCHEMA](<show-catalog-schema.md>)
-- 列出CATALOG下的表
-参考[列出CATALOG下的表](<show-catalog-table.md>)
-- 查寻CATALOG下的表
-参考[查询CATALOG下的表](<show-catalog-table.md>)
-- 创建CATALOG下的表结构
-参考[查看CATALOG下的表结构](<desc-catalog-table.md>)
-
-# 权限
-目前创建的 Catalog 只有 instance admin 角色可以查询。
-# 使用案例
-[参考创建HIVE CATALOG](<create-hive-catalog.md>)

-# HUDI外部表
->**【预览发布】本功能当前处于公开预览发布阶段。**
-
-HUDI为数据湖中的数据引入了结构化存储层，极大地提升了数据湖的易用性，使其操作体验接近于数据仓库。通过Lakehouse支持的外部表功能，用户能够便捷地访问和操作这些结构化数据。
-
-## 创建HUDI格式外部表
-
-\[创建外部表语法]\(create-external-table.md)
-
-**示例**
-
-```SQL
---创建conneciton
-CREATE STORAGE CONNECTION if not exists oss_hudi
-    TYPE oss
-    ENDPOINT = 'oss-cn-beijing.aliyuncs.com'
-    access_id = 'xxx'
-    access_key = 'xxxx'
-    comments = 'hudi';
---创建外部表,使用上面的连接信息
-CREATE EXTERNAL TABLE IF NOT EXISTS sales_data
-(
-  order_id INT,
-  product_id STRING,
-  sale_amount DOUBLE
-)
-PARTITIONED BY (dt STRING)
-USING HUDI
-CONNECTION oss_hudi
-LOCATION 'oss://my-bucket/data/sales'
-COMMENT 'External table for sales data stored in OSS';
-```
-
-## 删除外部表
-
-```SQL
-DROP TABLE [ IF EXISTS ] [schema_name.]<table_name
-```
-
-**参数说明**
-
-* `IF EXISTS`：可选，如果指定的表不存在，系统不会报错。
-* `schema_name`：可选，指定 schema 的名称。如果未指定，默认使用当前用户的 schema。
-* `table_name`：要删除的表名称。
-
-**说明**
-
-* 删除外部表并不会删除数据，因为数据存储在外部系统中，删除操作只会删除表的映射信息。
-
-**示例**
-
-```SQL
---删除已经创建的外部表
-DROP TABLE sales_data;
---删除名为 sales_data 的表，如果表不存在，不报错：
-DROP TABLE IF EXISTS sales_data;
---删除名为 my_schema 下的 sales_data表
-DROP TABLE my_schema.my_table;
-```
-
-## 查看外部表详情
-
-```SQL
-DESC[RIBE] [TABLE] [EXTENDED] table_name;
-```
-
-**参数说明**
-
-* **DESC\\\[RIBE]**：DESC和DESCRIBE可以互换使用，都表示描述表结构的命令。
-* **TABLE**：可选参数，用于指定查看表结构的类型，如BASE TABLE或VIEW等。
-* **EXTENDED**：可选参数，加入此关键字后，可以展示更多扩展信息，如表的创建语句和Location信息等。
-* **table\\\_name**：指定需要查看结构的表名。
-
-## 修改外部表
-
-### 重命名表
-
-通过ALTER TABLE命令，您可以将现有的表重命名为新的表名。
-
-**语法**
-
-```SQL
-ALTER TABLE name RENAME TO new_table_name;
-```
-
-**示例**
-
-```SQL
-ALTER TABLE old_table_name RENAME TO new_table_name;
-```
-
-### 修改表注释
-
-通过ALTER TABLE命令，您可以为表添加或修改注释。
-
-**语法**
-
-```SQL
-ALTER TABLE tbname SET COMMENT '';
-```
-
-**示例**
-
-```SQL
-ALTER TABLE scores SET COMMENT '这是一个成绩表';
-```
-
-## **外部表计费**
-
-* **存储费用**：外部表不产生存储费用，因为数据不存储在 Lakehouse 中。
-* **计算费用**：使用外部表进行计算会消耗计算资源，因此会产生计算费用。
-
-## **外部表权限**
-
-外部表和内部表权限点相同。由于外部表无法执行 INSERT、UPDATE、TRUNCATE、DELETE、UNDROP 等操作，因此没有对应的操作权限点。
-
-* **创建权限**：需要具有创建表（create table）的权限。
-* **删除权限**：需要具有删除（DROP）权限。
-* **读取权限**：需要具有选择（select）权限。
-
-## **使用注意事项**
-
-* **连接配置**： 创建 connection 时，确保 endpoint 配置正确，以便 Lakehouse 能够成功连接。如果 Lakehouse 和对象存储位于同一云服务且在同一区域，通常使用内网地址即可实现网络互通。如果不在同一网络环境，建议使用对象存储的公网地址。
-
-## 具体案例
-
-### 连接阿里云Oss
-
-```SQL
---创建connection,用于连接对象存储
-CREATE STORAGE CONNECTION  oss_hudi
-    TYPE oss
-    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com'
-    access_id = 'xxxxxx'
-    access_key = 'xxxxxx'
-    comments = 'hudi'
-    ;
---使用上面的链接信息，创建外部表
-CREATE    EXTERNAL TABLE pepole_hudi (id int, name string,dt string) 
-USING HUDI 
-CONNECTION oss_hudi 
-PARTITIONED BY (dt ) 
-LOCATION 'oss://bucketmy/hudi-format/uploadhudi/' 
-COMMENT 'external';
-```
-
-### 连接Google GCS
-
-Lakehouse 连接 Google Cloud Storage (GCS) 时，将使用服务账号密钥进行身份验证。请按照以下步骤操作：
-
-1. **获取服务账号密钥**：
-
-* 登录 Google Cloud 控制台。
-* 按照 *[Google Cloud 文档](https://cloud.google.com/docs/authentication/getting-started)* 的指导，创建并下载服务账号的 JSON 密钥文件。
-
-2. **配置 ****`private_key`**** 参数**：
-
-* 打开下载的 JSON 密钥文件，将文件中的私钥内容完整复制
-
-3. **注意**：
-
-* 在配置 `private_key` 时，必须前面添加r,r代表区分大小写，殊字符和 unicode 字符都不会被转义。

-# **外部表简介**
-
-**功能概述：** 外部表是 Lakehouse 的一项特性，它使您能够查询存储在外部系统中的数据，就如同这些数据存储在 Lakehouse 内部一样。这些外部数据并不存储或管理在 Lakehouse 中。
-
-**性能提示：** 由于外部表中的数据存储在 Lakehouse 外部，查询外部表可能比查询存储在本地的表稍慢。为了提升查询效率，建议使用 `INSERT INTO internal_table_name SELECT * FROM external_table_name` 语句或 `COPY INTO` 命令将数据导入到 Lakehouse 中。
-
-## 支持的外部表数据源
-- Kafka 外部表
-- Delta Lake 外部表
-- Hudi 外部表
-## **外部表与 External Schema 的区别**
-
-* **External Schema：** 直接与 Hive 元数据服务（HMS）交互，通过 HMS 接口直接获取 Hive 的元数据信息。
-* **外部表：** 允许用户自定义创建表，指定列内容和表名。
-* **External Schema 限制：** 由于是直接映射 HMS，无法在 External Schema 下直接创建、删除表或重命名表。
-* **外部表优势：** 支持重命名和修改注释等操作，因为它们是在内部 schema 下创建的。

-   2. 按照 *[Google Cloud 文档](https://cloud.google.com/docs/authentication/getting-started)* 的指导，创建并下载服务账号的 JSON 密钥文件。
-
-2. **配置 `private_key` 参数**：
-   1. 打开下载的 JSON 密钥文件，将文件中的私钥内容完整复制。
-
-3. **注意**：
-   1. 在配置 `private_key` 时，在 `private_key` 添加 `r`，表示转义字符不会被转义。

-CREATE STORAGE CONNECTION  oss_delta
-    TYPE gcs
-    private_key=r'{
-  "type": "service_account",
-  "project_id": "PROJECT_ID",
-  "private_key_id": "KEY_ID",

-PARTITIONED BY (dt ) 
-LOCATION 'gs://bucketmy/delta-format/uploaddelta/' 
-COMMENT 'edelta-external';
-```
-
-
-
-## **外部表计费**
-
-* **存储费用：** 外部表不产生存储费用，因为数据不存储在 Lakehouse 中。
-* **计算费用：** 使用外部表进行计算会消耗计算资源，因此会产生计算费用。
-
-## **外部表权限**
-
-外部表和内部表的权限点相同。由于外部表无法执行 INSERT、UPDATE、TRUNCATE、DELETE、UNDROP 等操作，因此没有对应的操作权限点。
-
-* **创建权限：** 需要具有创建表（create table）的权限。
-* **删除权限：** 需要具有删除（drop）权限。
-* **读取权限：** 需要具有选择（select）权限。
-
-## **使用注意事项**
-
-* **连接配置：** 创建 Connection 时，确保 Endpoint 配置正确，以便 Lakehouse 能够成功连接。如果 Lakehouse 和对象存储位于同一云服务且在同一区域，通常使用内网地址即可实现网络互通。如果不在同一网络环境，建议使用对象存储的公网地址。

-## **3. 配置指南**
-
-### **3.1 外部Catalog配置**
-
-#### **创建Catalog连接**
-
-```SQL
--- 创建连接到Databricks的Catalog连接
-CREATE CATALOG CONNECTION IF NOT EXISTS databricks_conn 
-TYPE databricks 
-HOST = 'https://dbc-12345678-9abc.cloud.databricks.com' 
-CLIENT_ID = 'client_id_value' 
-CLIENT_SECRET = 'client_secret_value' 
-ACCESS_REGION = 'us-west-2';
-
--- 创建连接到Hive的Catalog连接
-CREATE CATALOG CONNECTION IF NOT EXISTS hive_conn
-TYPE hms
-hive_metastore_uris = 'metastore-host'
-storage_connection = 9083;
-```
-
-#### **创建外部Catalog**
-
-```SQL
--- 基于上面的连接创建外部Catalog
-CREATE EXTERNAL CATALOG databricks_catalog 
-CONNECTION databricks_conn;
-
-CREATE EXTERNAL CATALOG hive_catalog
-CONNECTION hive_conn;
-```
-
-### **3.2 外部Schema配置**
-
-```SQL
--- 创建映射hive中的databse
-CREATE EXTERNAL SCHEMA external_db_schema 
-CONNECTION hive_catalog 
-OPTIONS ( 'schema'='default');
-```
-
-### **3.3 外部表配置**
-
-```SQL
--- 创建Delta Lake外部表
-CREATE EXTERNAL TABLE delta_sales
-USING DELTA 
-CONNECTION oss_delta 
-LOCATION 'oss://bucketname/delta-format/sales/' 
-COMMENT 'Delta外部表示例';
-
--- 创建Kafka外部表
-CREATE EXTERNAL TABLE kafka_messages (
-  key STRING,
-  value STRING,
-  topic STRING,
-  partition INT,
-  offset BIGINT,
-  timestamp BIGINT
-)
-USING KAFKA
-CONNECTION kafka_conn
-OPTIONS (
-  'kafka.bootstrap.servers' = 'broker:9092',
-  'subscribe' = 'test-topic'
-);
-```
-
-## **4. 查询使用**
-
-### **4.1 查询外部Catalog中的表**
-
-```SQL
--- 使用三层语法查询外部Catalog中的表
-SELECT * FROM databricks_catalog.default.sales 
-WHERE region = 'APAC'
-LIMIT 10;
-
--- 关联查询外部Catalog和内部表
-SELECT a.customer_id, a.order_total, b.customer_name
-FROM databricks_catalog.sales.orders a
-JOIN internal_schema.customers b
-ON a.customer_id = b.id
-WHERE a.order_date >= '2024-01-01';
-```
-
-### **4.2 查询外部Schema中的表**
-
-```SQL
--- 查询外部Schema中的表
-SELECT * FROM external_db_schema.customer_table
-WHERE register_date > '2023-01-01';
-```
-
-### **4.3 查询外部表**
-
-```SQL
--- 查询Delta外部表
-SELECT product, SUM(price) as total_sales
-FROM delta_sales
-WHERE sale_date BETWEEN '2024-01-01' AND '2024-04-30'
-GROUP BY product
-ORDER BY total_sales DESC;
-
--- 查询Kafka外部表
-SELECT * FROM kafka_messages
-WHERE timestamp > 1715132800000 -- 2024-05-08 00:00:00 UTC
-LIMIT 100;
-```
-
-## **5. 性能优化最佳实践**
-
-### **5.1 数据导入策略**
-
-由于外部表中的数据存储在Lakehouse外部，查询性能可能不如内部表。对于频繁查询的数据，建议导入到内部表：
-
-```SQL
--- 将外部表数据导入内部表
-INSERT INTO internal_sales_table 
-SELECT * FROM databricks_catalog.sales.orders
-WHERE order_date >= '2024-01-01';
-
-```
-
-### **5.2 分区和筛选**
-
-利用分区信息和筛选条件减少数据扫描量：
-
-```SQL
--- 使用分区筛选
-SELECT * FROM delta_sales
-WHERE sale_date = '2024-05-15'  -- 此处使用分区字段可大幅提升性能
-AND product = 'Laptop';
-```
-
-## **6. 管理和监控**
-
-### **6.1 查看外部对象**
-
-```SQL
--- 查看所有Catalog
-SHOW CATALOGS;
-
--- 查看所有外部Schema
-SHOW SCHEMAS EXTENDED WHERE type='external';
-
--- 查看外部Schema中的表
-SHOW TABLES IN external_db_schema;
-
--- 检查外部表结构
-DESCRIBE TABLE delta_sales;
-```
-
-## **7. 典型案例**
-
-### **7.1 数据湖与数据仓库统一查询**
-
-场景：企业同时拥有Hive数据湖和Databricks数据仓库，需要进行跨平台分析。
-
-解决方案：
-
-1. 创建连接到Hive和Databricks的外部Catalog
-2. 使用联邦查询关联两个平台的数据
-3. 构建统一视图提供一致的数据访问层

-# 任务调度和实例执行方式
-
-## 概要说明
-
-### 概念说明
-
-在任务开发场景中，离线任务都是周期性的运行（比如一天多次，一天一次等），除此之外，任务之间往往还会存在上下游的依赖关系，并按照依赖依次执行。像这种周期性的、有任务上下游依赖关系的就是调度的核心概念。
-
-### 任务与实例
-
-当用户在开发中，将一个开发脚本提交至生产环境后，即生成一个周期任务。一个周期任务每运行一次，就会生成一个周期实例，每个周期实例中可能会包含多次执行记录，例如自动重跑。
-
-因此，周期任务与周期实例往往是一对多的关系。
-
-## 调度系统的运作规则
-
-调度系统的任务主要是两方面：**生成实例**和**按计划运行实例**。具体概念如下：
-
-### 生成实例
-
-当任务提交到调度系统后，系统会根据调度配置的信息来生成实例。当前系统内提供两种生成实例的方式：
-
-* 次日生效：当日晚上22:00统一生成第二天的所有需要执行的实例。
-* 发布后立刻生效：即从用户点击提交后，系统会立即生成当天需要立即执行的实例。第二天的实例则按照系统默认的方式在晚上22:00统一生成。
-
-具体生成规则，在调度属性配置「实例生成」中详细介绍。
-
-### 按计划运行运行实例
-
-每天按计划运行实例时，调度系统判断一个实例是否可以运行，一般情况下需要满足两个条件：
-
-* 任务是否到达了计划时间
-* 上游任务是否全部成功
-
-^
-
-若满足了以上两个条件，调度系统就会将该实例任务提交执行。当该实例任务获取到相应的资源后就会正常的如期执行**实例运行**。
-
-若不能满足以上两个条件，任务实例会处于**未开始**的状态。但是为了避免任务实例因为配置或上游暂停等情况导致大批量的任务实例长期处于未开始的状态，导致资源浪费。系统会基于用户配置的「调度等待时长」执行kill操作，即该任务实例会被系统直接判定为失败状态。
-
-| 注意：  若生产环境中的周期任务未配置调度等待时长，则默认实例的调度等待时长为3天。即：当该任务到达了计划时间时，3天后无论上游任务是否全部成功，都会从**未开始**状态变更为**失败**状态。  若用户在调度配置中配置了「调度等待时长」，则待任务达到了计划时间时，无论上游任务是否全部成功，一旦超过了调度等待时长，任务实例状态均会从**未开始**状态变更为**失败**状态。 |
-| -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-
-## 调度属性配置
-
-在「开发」模块下，打开任意一个任务，点击调度配置功能，即可配置该任务的一系列调度属性信息。包括基础信息、调度时间、实例信息、调度依赖、任务产出等。
-
-*本文重点介绍*调度时间、实例信息、调度依赖，*其他内容可参考帮助文档*，
-
-### 调度时间
-
-![](.topwrite/assets/f6fc6447ee/b35ef5af588033e07f3e757c89edfd025ec25ca6.png =582)
-
-***
-
-**调度周期**：可配置调度周期、调度频次、开始调度时间、结束调度时间。当用户配置完这些信息后，系统会基于配置自动生成符合规则的标准cron表达式。自动生成该时间表达式会被调度引擎解析，通过时间轮算法推演出未来周期内所有符合条件的具体执行实例。
-
-当前系统内的调度频次有分钟、小时、天三种。如果一个任务的Cron表达式在天以上的位置，比如周，月，年等区域，设置了取值为单一值或多值（而不是\*）的，只要这些位置的取值不冲突，合法，那么不改变该任务的原有时间类型（不会变成周，月，年任务），只是约束了任务具体在哪些天跑，是这些天里的分钟，小时，天任务。（换句话说，其实没有周，月，年任务的概念）
-
-例如：
-
-* 每个月1号，3号，一个任务在指定时间跑一次，那就是一个日任务，而不是月任务
-* 每周1，和周3这两天里，一个任务每隔两小时跑一次，那就是一个小时任务，而不是周任务，也不是天任务
-* 分钟任务类似，当任务的间隔是分钟级别的，那就是一个分钟任务。
-
-***
-
-**生效日期**：指当前调度任务的调度生效日期范围。支持用户选择永不结束或者指定日期。
-
-永不结束即永久生效，目前系统是到2099年。
-
-若用户指定了日期，那么当超出生效日期后，此调度任务的实例不会再生成。
-

-![](.topwrite/assets/f6fc6447ee/9260e6641b50d8940c20836bfdb9330b4ba7eeab.png =556)
-
-**实例生成**：基于用户配置的**调度配置信息和依赖关系**，**按照用户选择的实例生成的规则生成相应的实例**。
-
-发布后生效：从提交任务后立刻生效，具体实例变更/生成范围是：
-
-* 提交时间 早于 调度开始时间，以调度开始时间开始，更新/生成后续的实例
-* 提交时间 晚于 调度开始时间，那么自提交发布时间后，会更新/生成相应的实例
-* 历史已生成的不影响，仅从起始时间开始向后变更后续的实例。
-
-![](.topwrite/assets/f6fc6447ee/94bccbdeead608afb473198307e1466cab001784.jpeg =757)
-
-次日生效：当日晚上22:00统一生成第二天的所有需要执行的实例：
-

-
-#### 实例重跑方式
-
-![](.topwrite/assets/f6fc6447ee/6d2c0d8953eac7b7256337937f6f795fd084a154.png =522)
-
-产品内提供了三种重跑方式，主要会作用在以下两种场景的行为：
-
-* 实例运行失败后，是否由系统自动重跑。
-* 实例运行成功或失败后，是否运行用户在运维中心的实例运维列表下，点击重跑操作。
-
-***
-
-不同取值方式和行为定义如下：
-
-* **运行成功或失败，都可以重跑** ：选择这种方式后，还需额外设置「实例自动重跑次数」和「实例重跑时间间隔」。选择该行为后，当实例运行失败时，系统会基于配置的重跑次数和间隔，依此触发自动重跑，一旦运行成功或到达重跑约定次数后，不再触发自动重跑的能力。同时可以在运维中心中找到该实例，无论该实例的状态时成功还是失败，均支持用户手动点击重跑操作，触发重跑行为。
-* **运行失败可以重跑，运行成功不可以重跑**：具体行为同上，唯一区别在于。在运维中心操作时，若该实例的状态是成功的，则不允许点击重跑操作。
-* **运行成功或失败，都不可以重跑**：选择该方式后，不会触发自动重跑行为，同时也不允许用户在运维中心点击重跑操作。
-
-#### 运行超时时长
-
-![](.topwrite/assets/f6fc6447ee/e99998089947ef23c63b79f948c107be37e9cac6.png =602)
-
-当用户配置了运行超时时长时，若该任务实例运行时间超过设置的时间后会被强制kill，运行状态变更为失败。目的是当一个任务长时间处于「运行中」状态时，会导致资源的占用，通过设置“超时时间”，可以及时释放资源。
-
-#### 调度等待时长
-
-![](.topwrite/assets/f6fc6447ee/7eb115526d02c946b30b1b2b9d78730794eb5d85.png =619)
-
-配置调度等待时长后，当任务实例到达计划运行时间后，无论上游是否成功执行均会触发强制kill的行为。该配置主要用于上游任务因暂停导致大批量下游实例无法执行导致的资源浪费，建议谨慎配置。
-
-### 调度依赖
-
-调度依赖是指周期调度节点间的上下游依赖关系。通过节点的依赖关系有序调度运行上下游节点，即当上游节点运行成功后，下游节点才会启动运行，保障适时的产出有效业务数据。
-
-更多调度依赖相关的实例执行行为见：[任务调度依赖关系](task_scheduling_dependency.md)
-
-## 运维操作
-
-### 周期任务
-
-* **暂停**：周期任务中状态是「正在调度」的可支持点击暂停。点击暂停后，自当前触发开始往后的所有实例任务均会被置为「暂停」。所有实例的概念包括：当天已生成的且未运行的实例，以及每天22点生成的第二天的所有实例。即虽然用户点击了暂停操作，但是仅是操作了实例的状态，并不阻塞该任务按期生成实例的行为。暂停行为仅是将该周期任务中的实例置为暂停状态，下游状态通常情况下会收到暂停的任务阻塞而导致无法运行。但是若下游任务配置了调度等待时长（或下游任务的自计划开始运行开始调度等待时长超过3天），那么下游任务会被强制kill。
-* **启动**：周期任务中状态是「暂停调度」的可支持点击启动。点击启动后，当前周期任务中所有暂停的实例均会触发执行的行为。
-* **下线**：周期任务直接下线后，在周期任务中不会进行任务管理，同时也不会再生成实例。若当前任务有下游任务正在运行，则不允许直接下线。需先将下游任务下线后，或点击下线（含下游）任务将当前任务即下游全部下线。
-* **补数**：无论周期任务的状态是什么，均支持用户点击补数操作。用户触发补数行为后，会在补数任务中生成一个对应的补数任务。
-
-^
-
-### 实例运维
-
-* **重跑**：只有执行结束的周期实例才可以操作重跑功能。且不同状态是否能重跑取决于用户在调度配置中的具体选项。若用户配置了 **运行成功或失败，都不可以重跑**，则也不允许点击重跑。用户在重跑操作上支持选择跑当前节点，或下游节点的能力。若用户有代码调整，并希望将某个节点按照最新代码重跑，则可以勾选使用最新代码和配置的能力，直接执行重跑操作。
-* **暂停**：对于处于非暂停状态的任务实例才可操作。操作后，会把任务实例的调度属性设置为“暂停调度”，即不再调度运行该任务实例。
-* **恢复**：对于处于暂停状态的任务实例才可操作。操作后，会把任务实例的调度属性恢复为“正常调度”，即按照设定的调度时间来运行任务实例。
-* **终止**：对于运行中的任务实例才可以操作。操作后，会终止任务实例的运行、把任务实例状态置为失败。
-* **置成功**：对于运行失败的任务实例才可以操作。操作后，强制将该任务实例置为成功。可用于紧急运维场景，在判断当前任务实例即使失败，也不影响下游任务的数据正确性的前提下，解除对下游任务实例运行的阻塞。
-* **置失败**：对于运行成功的任务实例才可以操作。操作后，强制将该任务实例置为失败。

-帆软BI（FineBI） 是帆软软件有限公司推出的一款商业智能（Business Intelligence）产品。FineBI 是新一代大数据分析的 BI 工具，旨在帮助企业的业务人员充分了解和利用他们的数据。本文介绍使用Mysql协议来连接Lakehouse
-
-# 准备工作
-
-* 请参考[FineBI官网](https://www.finebi.com/)，如果已经安装完毕请跳过。
-
-* 使用Mysql协议连接。目前需要重置密码，即使是新建的账号也需要重置密码。这是因为 MySQL 5.x 版本使用的是 `mysql_native_password` 密钥，而 Lakehouse 需要保存 MySQL 的加密算法。目前，只有在修改密码时，Lakehouse 才会保存 MySQL 密钥的加密算法。您可以修改密码时保持和之前一样这样可以避免影响别的任务连接
-
-* 给用户设置计算集群，由于 MySQL 协议中没有传入设置集群的方式，用户可以使用 SQL 命令为用户添加一个默认计算集群。这样在 MySQL 连接时就会使用该集群。
-
-  * ```SQL
-    ALTER USER user_name SET DEFAULT_VCLUSTER = default;-- 查看集群设置是否生效SHOW USERS;
-    ```
-
-* 准备用户名。 MySQL 协议连接地址时只能传入一个URL无法拼接Lakehouse的instace name和worksapce name,因此需要将。instace name和worksapce name拼接到用户名中
-
-  *   用户名格式要求如下：
-
-  * ```Plain
-    登录的账号名称@instance_name.workspace_name
-    ```
-
-  * **instance\_name 获取**：在 工作空间页面 中获取 JDBC 连接串。例如，在 `jdbc:clickzetta://``jnsxwfyr.api.clickzetta.com/quick_start?virtualCluster=default` 中，`jnsxwfyr` 为 instance\_name。
-  * **workspace\_name 获取**：工作空间的名称。
-
-# 在帆软BI（FineBI）配置连接Lakehouse
-
-* 在数据连接->数据连接管理中->新建数据连接->选择MySQL
-* 填写配置信息，如下图案例

-# 功能简介
-
-Lakehouse 通过 flink-connector-lakehouse 插件，实现了与 Flink 的无缝对接，使得数据能够高效地写入 Lakehouse。该插件采用实时接口进行数据写入，确保了数据处理的时效性。
-
-Lakehouse 提供了两种 Flink Connector 写入模式：igs-dynamic-table 和 igs-dynamic-table-append-only，以满足不同场景下的需求。
-
-1. **igs-dynamic-table**：支持追加模式和Flink CDC场景。在这种模式下，当 Flink 作为数据源接入 CDC 日志时，如果源端包含 update、delete 及 insert 操作，并且 Lakehouse 服务端表设置了主键属性，使用 igs-dynamic-table 将触发数据的更新和删除操作。支持在Lakehouse中[主键表](primary-key.md)写入。
-2. **igs-dynamic-table-append-only**：特别适用于不希望进行数据更新或删除的场景。即使在 Flink CDC 同步数据时，该模式也能确保数据仅进行追加操作，避免了不必要的数据变更。如果您的目标是避免数据的删除和更新，选择 igs-dynamic-table-append-only 将是一个更安全的选择。这样，您的数据将始终保持原始状态，不会被后续操作所影响。支持Lakehouse普通表写入。
-
-| **类别** | **详情**            |
-| ------ | ----------------- |
-| 支持的类型  | 只支持结果表，不支持作为源表和维表 |
-| 运行模式   | 流模式               |
-
-# 版本兼容
-
-| Flink Version       | Lakehouse Flink Connector Version |
-| ------------------- | --------------------------------- |
-| 1.14、1.15、1.17 | 请联系Lakehouse支持                    |
-
-使用Flink CDC时推荐使用版本 >= 2.3。
-
-# 使用
-
-## Maven引入
-
-Maven仓库坐标如下：
-
-```Plain
-<dependency>
-<groupId>com.clickzetta</groupId> 
-<artifactId>igs-flink-connector-${对应的flink版本}</artifactId>
-<version>请联系Lakehouse支持</version>
-</dependency>
-```
-
-## 使用方法
-
-### TABLE API方式写入
-
-```Java
--- First, define your data source
-CREATE TABLE source_table (
-  col1 INT,
-  col2 INT,
-  col3 VARCHAR
-) WITH (
-  'connector' = 'your-source-connector',
-  'property1' = 'value1'
-);
-
--- Second, define IGS table sink
-CREATE TABLE mock_table (
-  col1 INT,
-  col2 INT,
-  col3 VARCHAR
-) WITH (
-  'connector' = 'igs-dynamic-table',
-  'curl' = 'jdbc:clickzetta://{instance-name}.{regin}.api.clickzetta.com/default?username=user&password=******&schema=public',
-  'schema-name' = 'public',
-  'table-name' = 'mock_table',
-  'sink.parallelism' = '1',
-  'properties' = 'authentication:true'
-);
-
--- Third, execute the data transfer
-INSERT INTO mock_table
-SELECT * FROM source_table;
-```

-## 实时数据同步：使用Flink CDC将MySQL数据写入Lakehouse主键表
-
-### 概述
-
-本文详细介绍了如何通过Lakehouse的flink connector使用igs-dynamic-table模式，实现MySQL数据库的变更数据捕获（CDC）日志实时同步到Lakehouse的主键表中。在igs-dynamic-table模式下，Lakehouse主键列的数据能够自动更新，确保数据的一致性和实时性。
-
-### STEP 1:环境准备
-
-* 使用IntelliJ IDEA作为开发工具，需具备Flink编程能力。
-* 获取Lakehouse连接信息，可在Lakehouse Studio管理 -> 工作空间中查看JDBC连接串，如下：
-![](../.topwrite/assets/image_1728887857029.png)
-
-```SQL
-jdbc:clickzetta://6861c888.cn-shanghai-alicloud.api.clickzetta.com/quickstart_ws?username=xxx&password=xxx&schema=public
-```
-
-* 本地搭建的Mysql数据库
-
-* 下载Lakehouse提供的Flink Connector包（目前由Lakehouse支持提供下载包），下载完成后将JAR包打入到本地Maven仓库中，方便在Maven项目中引用和打包。
-
-  * ```SQL
-    mvn install:install-file -Dfile=igs-flink-connector-15-0.11.0-shaded.jar -DgroupId=com.clickzetta -DartifactId=igs-flink-connector-15 -Dversion=0.11.0 -Dpackaging=jar
-    ```
-
-* 修改pom.xml文件，添加如下依赖
-
-  * ```XML

-### STEP 2:在Mysql中创建表并插入测试数据
-
-```SQL
-create table people (id int primary key,name varchar(100));
-insert into people values(1,'a'),(2,'b'),(3,'c');
-```
-
-### STEP 3:在Lakehouse中创建主键表
-
-```SQL
-create table people (id int,name string,primary key(id));
-```
-
-Lakehouse的**主键（PRIMARY KEY）** 用于确保表中每条记录的唯一性。在Lakehouse架构中，定义了主键的表在进行实时数据写入时，系统将自动根据主键值进行数据去重，一旦设置了主键，您将无法通过SQL语句执行插入、删除、更新操作，也不能添加或删除列。
-
-### STEP 4:编写代码,并在IDEA启动任务
-
-```SQL

-
-        StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment()
-                .setParallelism(1);
-        env.setRestartStrategy(RestartStrategies.fixedDelayRestart(100, Time.seconds(60)));
-        //      env.enableCheckpointing(60000);
-//
-//
-//        env.getCheckpointConfig().setCheckpointingMode(CheckpointingMode.EXACTLY_ONCE);
-//
-//        env.getCheckpointConfig().setMinPauseBetweenCheckpoints(1000);
-
-// checkpoint 必须在 60s 内结束，否则被丢弃，默认是 10 分钟
-//        env.getCheckpointConfig().setCheckpointTimeout(60000);
-// 同一时间只能允许有一个 checkpoint
-//        env.getCheckpointConfig().setMaxConcurrentCheckpoints(1);
-// 最多允许 checkpoint 失败 3 次
-//        env.getCheckpointConfig().setTolerableCheckpointFailureNumber(3);
-// 当 Flink 任务取消时，保留外部保存的 checkpoint 信息
-//        env.getCheckpointConfig().enableExternalizedCheckpoints(CheckpointConfig.ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);
-        StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env);

-### STEP 5:数据同步验证
-
-* 启动完成后将会将mysql数据自动同步到lakehouse中，在Lakehouse中查询数据
-
-```SQL
-select * from people;
-+----+------+
-| id | name |
-+----+------+
-| 2  | b    |
-| 3  | c    |
-| 1  | a    |
-+----+------+
-```
-
-* 在mysql更新一条数据
-
-```SQL
-update people set name='A' where id=1;
-```
-
-* 在Lakehouse中查询，则会保持和mysql数据一致
-
-```SQL
-select * from people;
-+----+------+
-| id | name |
-+----+------+
-| 2  | b    |
-| 3  | c    |

-## 实时数据同步：使用Flink CDC将MySQL数据写入Lakehouse普通表中
-
-### 概述
-
-本文详细介绍了如何通过Lakehouse的flink connector使用igs-dynamic-table-append-only模式，实现MySQL数据库的变更数据捕获（CDC）日志实时同步到Lakehouse的普通表中。在igs-dynamic-table-append-only模式下，Lakehouse 将直接记录 CDC 原始日志，而不会更新Lakehouse中的数据。
-
-### STEP 1:环境准备
-
-* 使用IntelliJ IDEA作为开发工具，需具备Flink编程能力。
-* 获取Lakehouse连接信息，可在Lakehouse Studio管理 -> 工作空间中查看JDBC连接串，并将JDBC协议替换为igs。如下修改为：
-![](../.topwrite/assets/image_1728887857029.png)
-
-```SQL
-jdbc:clickzetta://6861c888.cn-shanghai-alicloud.api.clickzetta.com/quickstart_ws?username=xxx&password=xxx&schema=public
-```
-
-* 本地搭建的Mysql数据库
-
-* 下载Lakehouse提供的Flink Connector包（目前由Lakehouse支持提供下载包），下载完成后将JAR包打入到本地Maven仓库中，方便在Maven项目中引用和打包。
-
-  * ```SQL
-    mvn install:install-file -Dfile=igs-flink-connector-15-0.11.0-shaded.jar -DgroupId=com.clickzetta -DartifactId=igs-flink-connector-15 -Dversion=0.11.0 -Dpackaging=jar
-    ```
-
-* 修改pom.xml文件，添加如下依赖

-### STEP 2:在Mysql中创建表并插入测试数据
-
-```SQL
-create table people_append (id int primary key,name varchar(100));
-insert into people_append values(1,'a'),(2,'b'),(3,'c');
-```
-
-### STEP 3:在Lakehouse中创建普通表
-
-```SQL
-create table people_append (id int,name string,source_operate string);
-```
-
-`source_operate` 字段用于记录 MySQL 中的日志操作。在 Lakehouse Flink Connector 中配置 `mapping.operation.type.to`，可以指定 CDC 的操作符落入 Lakehouse 表中的字段名。
-
-### STEP 4:编写代码,并在IDEA启动任务

-
-        StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment()
-                .setParallelism(1);
-        env.setRestartStrategy(RestartStrategies.fixedDelayRestart(100, Time.seconds(60)));
-        //      env.enableCheckpointing(60000);
-//
-//
-//        env.getCheckpointConfig().setCheckpointingMode(CheckpointingMode.EXACTLY_ONCE);
-//
-//        env.getCheckpointConfig().setMinPauseBetweenCheckpoints(1000);
-
-// checkpoint 必须在 60s 内结束，否则被丢弃，默认是 10 分钟
-//        env.getCheckpointConfig().setCheckpointTimeout(60000);
-// 同一时间只能允许有一个 checkpoint
-//        env.getCheckpointConfig().setMaxConcurrentCheckpoints(1);
-// 最多允许 checkpoint 失败 3 次
-//        env.getCheckpointConfig().setTolerableCheckpointFailureNumber(3);
-// 当 Flink 任务取消时，保留外部保存的 checkpoint 信息
-//        env.getCheckpointConfig().enableExternalizedCheckpoints(CheckpointConfig.ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);

-# Lakehouse 全文检索使用指南
-
-***
-
-## 附录 写在前面
-
-## 附录# 您可能遇到的文本检索场景
-
-## 附录## 附录 场景1：企业知识库搜索系统
-
-**当前在Hive/Spark中的常见做法**：
-
-```sql
--- 在Hive中进行文本搜索
-SELECT * FROM knowledge_base 
-WHERE content LIKE '%人工智能%' 
-   OR content LIKE '%机器学习%' 
-   OR content LIKE '%深度学习%';
-
--- 性能问题：
--- 1. 全表扫描，无法利用索引
--- 2. 只能精确匹配，无法进行语义搜索
--- 3. 中文分词困难，搜索效果差
-```
-
-**面临的技术挑战**：
-
-* **性能限制**：LIKE查询需要全表扫描，大数据量时性能极差
-* **功能局限**：无法进行分词搜索，只能精确字符串匹配
-* **维护复杂**：需要手动管理搜索关键词和同义词
-* **扩展困难**：多语言支持需要额外开发
-
-## 附录## 附录 场景2：日志分析与故障排查
-
-**在Elasticsearch中的典型实现**：
-
-```javascript
-// Elasticsearch查询
-{
-  "query": {
-    "multi_match": {
-      "query": "ERROR timeout connection",
-      "fields": ["message", "stack_trace"]
-    }
-  }
-}
-```
-
-**常见的技术痛点**：
-
-* **架构复杂**：需要维护独立的搜索引擎系统
-* **数据同步**：数据需要从数据湖同步到搜索引擎
-* **成本问题**：额外的存储和计算资源消耗
-* **一致性风险**：数据同步延迟导致搜索结果不准确
-
-## 附录# 为什么需要原生全文检索
-
-基于以上场景中的技术挑战，Lakehouse原生全文检索的设计目标是：
-
-**统一的数据处理平台**：
-
-* 在同一系统中完成分析计算和全文检索
-* 无需维护独立的搜索引擎系统
-* 数据存储和检索的强一致性
-
-**高性能的倒排索引**：
-
-* 基于倒排索引的快速文本检索
-* 支持多种分词策略和语言
-* 比传统LIKE查询性能提升数十倍
-
-**智能的分词和匹配**：
-
-* 支持中文、英文、Unicode等多种分词器
-* 提供短语匹配、前缀匹配、正则匹配等多种模式
-* 自动大小写转换和标点符号过滤

-
-## 附录 快速开始
-
-## 附录# 基本使用流程
-
-```sql
--- 1. 创建包含倒排索引的表
-CREATE TABLE documents (
-    id BIGINT,
-    title STRING,
-    content STRING,
-    created_at TIMESTAMP,
-    
-    -- 建表时定义倒排索引
-    INDEX title_idx (title) INVERTED PROPERTIES('analyzer'='keyword'),
-    INDEX content_idx (content) INVERTED PROPERTIES('analyzer'='chinese', 'mode'='smart')
-);
-
--- 2. 插入数据
-INSERT INTO documents VALUES 
-(1, 'ClickZetta技术指南', '云器Lakehouse支持向量检索和全文搜索功能', CURRENT_TIMESTAMP());
-
--- 3. 为已有数据构建索引
-BUILD INDEX content_idx ON documents;
-
--- 4. 执行全文检索查询
-SELECT id, title FROM documents 
-WHERE MATCH_ANY(content, '全文搜索 向量检索', map('analyzer', 'auto'));
-
--- 5. 使用短语匹配
-SELECT id, title FROM documents 
-WHERE MATCH_PHRASE(content, '全文搜索功能', map('analyzer', 'auto'));
-```
-
-***
-
-## 附录 技术对比：传统方案 vs 原生全文检索
-
-## 附录# 传统LIKE查询方案
-
-```sql
--- 使用LIKE进行文本搜索
-SELECT * FROM documents 
-WHERE content LIKE '%人工智能%' 
-   OR content LIKE '%机器学习%'
-   OR content LIKE '%深度学习%';
-
--- 存在的问题：
--- 1. 全表扫描，性能差
--- 2. 无法分词，只能精确匹配
--- 3. 大小写敏感
--- 4. 无法处理同义词
-```
-
-## 附录# 外部搜索引擎方案
-
-```yaml
-# 需要维护额外的Elasticsearch集群
-version: '3'
-services:
-  elasticsearch:
-    image: elasticsearch:7.14.0
-    environment:
-      - discovery.type=single-node
-    ports:
-      - "9200:9200"
-```
-
-```python
-# 需要数据同步脚本
-from elasticsearch import Elasticsearch
-
-def sync_data_to_es():
-    # 从数据湖读取数据
-    # 转换格式
-    # 同步到Elasticsearch
-    pass
-```
-
-## 附录# Lakehouse原生全文检索
-
-```sql
--- 一站式解决方案
-CREATE TABLE documents (
-    id BIGINT,
-    content STRING,
-    INDEX content_idx (content) INVERTED PROPERTIES('analyzer'='chinese')
-);
-
--- 直接使用内置函数
-SELECT * FROM documents 
-WHERE MATCH_ALL(content, '人工智能 机器学习', map('analyzer', 'auto'));
-```

-## 附录 倒排索引核心概念
-
-## 附录# 倒排索引原理
-
-**基本概念**：
-
-* **词典（Dictionary）**：存储所有文档中出现的唯一单词列表
-* **倒排表（Posting List）**：记录每个单词在哪些文档中出现及位置信息
-
-**构建过程**：
-
-1. **分词（Tokenization）**：将文档内容分割成单词或短语
-2. **标准化（Normalization）**：转小写、去除停用词等处理
-3. **构建词典**：为每个单词分配唯一ID
-4. **构建倒排表**：记录单词与文档的映射关系
-
-## 附录# 索引创建语法
-

-
-## 附录 索引管理
-
-## 附录# 索引生命周期
-
-## 附录## 附录 1. 创建索引
-
-```sql
--- 方式1：建表时创建
-CREATE TABLE documents (
-    id BIGINT,
-    content STRING,
-    INDEX content_idx (content) INVERTED PROPERTIES('analyzer'='chinese')
-);
-
--- 方式2：为已有表创建
-CREATE INVERTED INDEX content_idx ON TABLE documents(content) 
-PROPERTIES('analyzer'='chinese', 'mode'='smart');
-```
-
-## 附录## 附录 2. 构建索引（重要！）
-
-```sql
--- 对已有数据构建索引（同步任务）
-BUILD INDEX content_idx ON documents;
-
--- 按分区构建索引
-BUILD INDEX content_idx ON documents 
-WHERE partition_date >= '2024-01-01';
-```
-
-⚠️ **关键提醒**：
-
-* `CREATE INDEX` 仅对新增数据生效
-* 已有数据必须执行 `BUILD INDEX` 才能利用索引
-* 构建索引会消耗计算资源，建议在业务低峰期执行
-
-## 附录## 附录 3. 查看索引
-
-```sql
--- 列出表上所有索引
-SHOW INDEX FROM table_name;
-
--- 查看索引详情（如果环境支持）
-DESC INDEX index_name;
-DESC INDEX EXTENDED index_name;  -- 包含大小信息
-```
-
-## 附录## 附录 4. 删除索引
-
-```sql
-DROP INDEX index_name ON table_name;
-```
-
-**删除特点**：
-
-* 立即删除元数据
-* 索引文件异步清理
-* 不影响数据本身
-
-## 附录# 索引性能调优
-
-## 附录## 附录 分区表索引策略
-
-```sql
--- 大表分区构建建议
-BUILD INDEX content_idx ON large_table 
-WHERE year = '2024' AND month = '01';
-
-BUILD INDEX content_idx ON large_table 
-WHERE year = '2024' AND month = '02';
--- 逐个分区构建，避免资源消耗过大
-```
-
-## 附录## 附录 存储成本优化
-
-```sql
--- 查看索引存储占用（如果支持）
-DESC INDEX EXTENDED index_name;
-
--- 根据业务需求选择合适的分词器
--- keyword: 存储最少，仅精确匹配
--- chinese: 中等存储，支持智能分词
--- unicode: 存储最多，支持全语言
-```

-## 附录 重要避坑指南
-
-## 附录# 分词器一致性问题
-
-## 附录## 附录 常见错误：分词器不匹配
-
-```sql
--- ❌ 错误示例：索引使用chinese分词，查询使用english分词
-CREATE TABLE docs (
-    content STRING,
-    INDEX content_idx (content) INVERTED PROPERTIES('analyzer'='chinese')
-);
-
-SELECT * FROM docs 
-WHERE MATCH_ANY(content, '测试', map('analyzer', 'english'));
--- 结果：无法利用索引，性能差
-```
-
-## 附录## 附录 正确做法：
-
-```sql
--- ✅ 方案1：使用auto参数（推荐）
-SELECT * FROM docs 
-WHERE MATCH_ANY(content, '测试', map('analyzer', 'auto'));
-
--- ✅ 方案2：手动匹配索引分词器
-SELECT * FROM docs 
-WHERE MATCH_ANY(content, '测试', map('analyzer', 'chinese'));
-```
-
-## 附录# 索引构建避坑
-
-## 附录## 附录 BUILD INDEX的必要性
-
-```sql
--- ❌ 常见错误：忘记构建索引
-CREATE INVERTED INDEX content_idx ON TABLE existing_table(content) 
-PROPERTIES('analyzer'='chinese');
-
--- 直接查询（只对新数据有效，已有数据无法利用索引）
-SELECT * FROM existing_table 
-WHERE MATCH_ANY(content, '关键词', map('analyzer', 'auto'));
-```
-
-## 附录## 附录 正确的索引构建流程
-
-```sql
--- ✅ 完整流程
--- 1. 创建索引
-CREATE INVERTED INDEX content_idx ON TABLE existing_table(content) 
-PROPERTIES('analyzer'='chinese');
-
--- 2. 构建索引（必须！）
-BUILD INDEX content_idx ON existing_table;
-
--- 3. 验证索引
-SHOW INDEX FROM existing_table;
-
--- 4. 执行查询
-SELECT * FROM existing_table 
-WHERE MATCH_ANY(content, '关键词', map('analyzer', 'auto'));
-```
-
-## 附录# 查询性能避坑
-
-## 附录## 附录 亚秒查询的性能限制
-
-根据官方文档：**在大多数情况下，倒排索引并不会显著提高执行时间为亚秒的查询的性能**。
-
-<1秒）
--- 3. 简单的等值查询
-
--- ✅ 适合倒排索引的场景
--- 1. 大数据量表（万行以上）
--- 2. 复杂的文本搜索
--- 3. 多关键词匹配
-```
-
-#### 不支持的查询模式
-
-```sql
--- ❌ 不支持：对列进行类型转换
-SELECT * FROM docs 
-WHERE MATCH_ANY(CAST(id AS STRING), '123', map('analyzer', 'auto'));
-
--- ✅ 支持：对查询值进行转换
-SELECT * FROM docs 
-WHERE MATCH_ANY(content, CAST(123 AS STRING), map('analyzer', 'auto'));
-
--- ❌ 不支持：外部表
--- 倒排索引不支持外部表
-```
-
-### 存储成本避坑
-
-#### 索引存储开销
-
-```sql
--- 倒排索引会创建额外的索引文件
--- 存储成本 = 原始数据 + 索引文件
-
--- 优化建议：
--- 1. 仅为真正需要搜索的列创建索引
--- 2. 根据查询模式选择合适的分词器
--- 3. 定期清理不必要的索引
-```

-### 查询优化策略
-
-#### 1. 合理选择查询函数
-
-```sql
--- 根据业务需求选择合适的函数
--- 精确搜索：使用 MATCH_ALL
-SELECT * FROM docs WHERE MATCH_ALL(content, '机器学习 算法', map('analyzer', 'auto'));
-
--- 宽泛搜索：使用 MATCH_ANY  
-SELECT * FROM docs WHERE MATCH_ANY(content, '人工智能 机器学习 深度学习', map('analyzer', 'auto'));
-
--- 短语搜索：使用 MATCH_PHRASE
-SELECT * FROM docs WHERE MATCH_PHRASE(content, '自然语言处理', map('analyzer', 'auto'));
-```
-
-#### 2. 组合查询优化
-
-```sql
--- ✅ 推荐：将全文检索作为主要过滤条件
-SELECT * FROM documents 
-WHERE MATCH_ANY(content, '关键词', map('analyzer', 'auto'))
-  AND category = 'tech'  -- 在全文检索基础上进行二次过滤
-  AND created_at >
-
-## 附录## 附录 3. 分页查询优化
-
-```sql
--- ✅ 高效的分页查询
-SELECT id, title FROM documents 
-WHERE MATCH_ANY(content, '关键词', map('analyzer', 'auto'))
-ORDER BY id  -- 使用主键排序
-LIMIT 20 OFFSET 0;
-
--- ⚠️ 避免深度分页
--- LIMIT 20 OFFSET 10000; -- 性能会随offset增大而下降
-```
-
-## 附录# 索引优化策略
-
-## 附录## 附录 1. 分区表索引管理

-## 生成列
-生成列（Generated Columns）是数据库表中的一列，其值由表中的其他列的值通过一个表达式自动计算生成。这种列在创建时就定义了一个计算规则，数据库管理系统会根据这个规则自动填充列的值，而不需要用户显式地插入或更新这些值。应用场景比如数据集成同步时不支持转化，可以使用生成列进行转化。
-
-## 语法
-
-```SQL
-CREATE TABLE [ IF NOT EXISTS ] table_name
-(
-    column_definition GENERATED ALWAYS AS ( expr ), [column_definition,...]
-)
-[ PARTITIONED BY (column_name column_type | column_name ) ];
-```
-
-
-* **GENERATED ALWAYS AS (expr)**：通过表达式`expr`自动生成列的值。表达式可以包含常量和内置标量确定性SQL函数，不支持非确定性函数如（current\_date\random\current\_timestamp\上下文函数）或运算符，不支持聚合函数、窗口函数或表函数。支持分区列使用生成列
-
-**示例**：
-
-```SQL
--- 正确使用
-CREATE TABLE t_genet (
-    col1 TIMESTAMP,
-    hour int GENERATED ALWAYS AS (hour(col1)),
-    pt STRING GENERATED ALWAYS AS (date_format(col1, 'yyyy-MM-dd'))
-) PARTITIONED BY (pt);
-```
-### 生成列和默认值区别
-
-1. **分区列支持**：
-
-   1. **默认值**：当前不支持为分区列设置默认值。
-   2. **生成列**：支持为分区列生成值。
-
-2. **函数支持**：
-
-   1. **默认值**：支持使用非确定性函数，如 `current_timestamp()`
-   2. **生成列**：不支持非确定性函数，只能使用确定性的标量函数。
-
-3. **插入操作中的值指定**：
-
-   1. **默认值**：在插入数据时，可以为列指定一个静态值，如果未指定，则使用默认值。
-   2. **生成列**：在插入数据时，不能为生成列指定值，其值完全由生成表达式决定。
-
-4. **列值来源**：
-
-   1. **默认值**：不支持列的值来自其他列的转换。
-   2. **生成列**：支持列的值来自其他列的转换，即可以基于其他列的值计算生成。
-
-5. **现有数据行的处理**：
-
-   1. **默认值**：当为现有表添加带有默认值的列时，已存在的数据行中的该列将填充为null。
-   2. **生成列**：对于已存在的数据行，生成列的值将根据生成表达式进行转换，并显示转换后的数据。
-
-### 使用限制
-
-* 使用生成列时，您不能在插入操作中显式指定该列的值，它将由表达式自动生成。但是为了兼容Hive语法，Lakehouse允许您为分区字段指定一个静态值。然而，指定的静态值不会生效，查询结果仍然是由指定生成列表达式结果决定
-* 不支持使用实时接口和批量接口写入，包括Studio数据集成的批量导入和实时写入。
-* 生成列不支持非确定性函数如（current\_date\random\current\_timestamp\上下文函数）或运算符，不支持聚合函数、窗口函数或表函数。
-
-### 插入数据
-
-* 当使用生成列时，您不能为该列指定常量值。例如，如果hour列是由`col1`生成的，您不能在插入时指定hour的值。指定则会报错。
-
-**错误示例**：
-
-```SQL
--- 指定的2024-09-26将不会生效，因为pt是由col1生成的，虽然不会报错，但是值不会写入当中
-CREATE TABLE t_genet (
-    col1 TIMESTAMP,
-    pt STRING GENERATED ALWAYS AS (date_format(col1, 'yyyy-MM-dd'))
-) PARTITIONED BY (pt);
-INSERT INTO t_genet (col1,pt) VALUES (current_timestamp, '2024-09-26');
-```
-
-**正确示例**：
-
-```SQL
--- 可以运行，只插入col1，pt将由生成规则自动计算
-INSERT INTO t_genet (col1) VALUES (current_timestamp);
-```
-
-# 添加字段时指定生成列
-
-## 语法
-
-```SQL
--- 添加列
-ALTER TABLE table_name ADD COLUMN
-      column1_name_identifier data_type [column_properties]
-      [FIRST | AFTER column1_name_identifier]  ,....
-
-column_properties:==
-    GENERATED ALWAYS AS ( expr ) |
-    COMMENT column_comment 
-```
-
-* **GENERATED ALWAYS AS (expr)**：指定一个表达式，用于自动生成新添加列的值。对于表中已存在的数据行，该列将根据表达式的结果填充值。表达式可以包含常量和内置标量确定性SQL函数，非确定性函数如（current\_date\random\current\_timestamp等）或运算符，不支持聚合函数、窗口函数或表函数。
-
-
-## 使用限制
-
-* 不支持在已有的列添加生成列
-
-## 示例
-
-### 添加生成列
-
-```SQL
-ALTER TABLE my_table ADD COLUMN
-    generated_col TIMESTAMP GENERATED ALWAYS AS (date_format(col1, 'yyyy-MM-dd')) FIRST;
-```
-
-在这个例子中，`generated_col` 将被添加为表中的第一列，并且所有现有的数据行的 `generated_col` 将根据当前时间戳生成值。

-* **标准兼容**：支持常用的确定性函数和表达式
-
-### 适用场景
-
-* 时间维度分析（按日期、小时等分组查询）
-* 数据分类和标准化（状态判断、等级划分）
-* 需要统一业务规则的场景
-* 基于计算结果进行分区的需求
-
-***
-
-## 基础语法
-
-### 创建语法
-
-```sql
--- 完整的CREATE TABLE语法
-CREATE TABLE table_name (
-    column_definition,
-    column_name data_type GENERATED ALWAYS AS ( expression ) [COMMENT comment],
-    [column_definition,...]
-) [ PARTITIONED BY (column_name) ];
-
--- ALTER TABLE添加生成列语法
-ALTER TABLE table_name ADD COLUMN 
-column_name data_type GENERATED ALWAYS AS ( expression ) 
-[COMMENT comment];
-```
-
-### 5分钟上手示例
-
-```sql
--- 创建表时定义生成列
-CREATE TABLE orders (
-    order_id INT,
-    order_time TIMESTAMP_LTZ,
-    amount DOUBLE,
-    order_date STRING GENERATED ALWAYS AS (date_format(order_time, 'yyyy-MM-dd')),
-    order_hour INT GENERATED ALWAYS AS (hour(order_time)),
-    amount_level STRING GENERATED ALWAYS AS (
-        if(amount >= 1000, 'HIGH',
-           if(amount >= 500, 'MEDIUM', 'LOW'))
-    )
-);
-
--- 插入数据：只需提供基础列
-INSERT INTO orders (order_id, order_time, amount) VALUES 
-(1001, TIMESTAMP '2024-06-19 14:30:00', 299.99);
-
--- 查询结果：自动包含生成列
-SELECT * FROM orders;
--- 结果：order_date='2024-06-19', order_hour=14, amount_level='LOW'
-
--- 后续添加生成列
-ALTER TABLE orders ADD COLUMN 
-year_col INT GENERATED ALWAYS AS (year(order_time)) COMMENT '年份列';
-```
-
-***
-
-## 验证清单
-
-### 创建后验证（每次必做）
-
-```sql
--- 1. 创建带生成列的表
-CREATE TABLE orders_test (
-    order_id INT,
-    order_time TIMESTAMP_LTZ,
-    amount DOUBLE,
-    hour_col INT GENERATED ALWAYS AS (hour(order_time)),
-    date_str STRING GENERATED ALWAYS AS (date_format(order_time, 'yyyy-MM-dd'))
-);
-
--- 2. 验证表结构
-DESCRIBE TABLE orders_test;
--- ✅ 检查：生成列是否出现在表结构中
-
--- 3. 测试数据插入
-INSERT INTO orders_test (order_id, order_time, amount) VALUES 
-(1001, TIMESTAMP '2024-06-19 14:30:00', 299.99);
-
--- 4. 验证生成列值
-SELECT order_id, order_time, hour_col, date_str FROM orders_test;
--- ✅ 检查：hour_col=14, date_str='2024-06-19'
-
--- 5. 验证插入保护机制
--- INSERT INTO orders_test (order_id, order_time, hour_col) VALUES 
--- (1002, TIMESTAMP '2024-06-19 15:30:00', 999);
--- ✅ 检查：应该报错"cannot insert or update generated column"
-
--- 6. 验证ALTER TABLE添加生成列
-ALTER TABLE orders_test ADD COLUMN 
-year_col INT GENERATED ALWAYS AS (year(order_time));
-
--- 7. 验证存量数据回填
-SELECT order_id, order_time, year_col FROM orders_test;
--- ✅ 检查：year_col=2024（存量数据自动计算）
-```

-## 平台迁移指导
-
-### MySQL迁移
-
-```sql
--- MySQL语法
--- CREATE TABLE mysql_table (
---     id INT,
---     price DECIMAL(10,2),
---     tax DECIMAL(10,2) AS (price * 0.1) STORED
--- );
-
--- 云器Lakehouse等价语法
-CREATE TABLE lakehouse_table (
-    id INT,
-    price DECIMAL(10,2),
-    tax DECIMAL(10,2) GENERATED ALWAYS AS (price * 0.1)
-);
-
--- 主要差异：
--- 1. MySQL: AS (expression) [STORED|VIRTUAL]
--- 2. Lakehouse: GENERATED ALWAYS AS (expression)
--- 3. Lakehouse只支持STORED模式（物理存储）
-```
-
-### PostgreSQL迁移
-
-```sql
--- PostgreSQL语法
--- CREATE TABLE postgres_table (
---     id INT,
---     first_name TEXT,
---     last_name TEXT,
---     full_name TEXT GENERATED ALWAYS AS (first_name || ' ' || last_name) STORED
--- );
-
--- 云器Lakehouse等价语法
-CREATE TABLE lakehouse_table (
-    id INT,
-    first_name STRING,
-    last_name STRING,
-    full_name STRING GENERATED ALWAYS AS (concat(first_name, ' ', last_name))
-);
-
--- 主要差异：
--- 1. 字符串连接：PostgreSQL用||，Lakehouse用concat()函数
-```
-
-### Oracle迁移
-
-```sql
--- Oracle虚拟列语法
--- CREATE TABLE oracle_table (
---     id NUMBER,
---     birth_date DATE,
---     age NUMBER GENERATED ALWAYS AS (
---         FLOOR(MONTHS_BETWEEN(SYSDATE, birth_date) / 12)
---     ) VIRTUAL
--- );
-
--- 云器Lakehouse调整后语法
-CREATE TABLE lakehouse_table (
-    id INT,
-    birth_date DATE,
-    -- Oracle的SYSDATE是非确定性的，需要重新设计
-    year_part INT GENERATED ALWAYS AS (year(birth_date))
-);
-
--- 主要差异：
--- 1. Oracle支持非确定性函数，Lakehouse不支持
--- 2. Oracle的CASE WHEN支持，Lakehouse需要用if()嵌套
-```
-
-### Hive/Spark迁移
-
-```sql
--- Hive/Spark通常使用视图
--- CREATE VIEW hive_view AS
--- SELECT id, event_time, 
---        hour(event_time) as hour_col,
---        date_format(event_time, 'yyyy-MM-dd') as date_str
--- FROM raw_table;
-
--- 云器Lakehouse生成列：真实物理存储，性能更好
-CREATE TABLE lakehouse_table (
-    id INT,
-    event_time TIMESTAMP_LTZ,
-    hour_col INT GENERATED ALWAYS AS (hour(event_time)),
-    date_str STRING GENERATED ALWAYS AS (date_format(event_time, 'yyyy-MM-dd'))
-);
-
--- 优势对比：
--- Hive/Spark视图：查询时计算，性能开销大
--- Lakehouse生成列：预计算存储，查询性能好
-```

-
-## 高级使用场景
-
-### 生成列 + 分区组合
-
-```sql
--- 时间分区自动化
-CREATE TABLE sales_auto_partition (
-    sale_id INT,
-    customer_id INT,
-    sale_time TIMESTAMP_LTZ,
-    amount DOUBLE,
-    sale_date STRING GENERATED ALWAYS AS (date_format(sale_time, 'yyyy-MM-dd'))
-) PARTITIONED BY (sale_date);
-
--- 插入数据：无需计算分区值
-INSERT INTO sales_auto_partition (sale_id, customer_id, sale_time, amount) VALUES 
-(1001, 5001, TIMESTAMP '2024-06-19 14:30:00', 299.99),
-(1002, 5002, TIMESTAMP '2024-06-20 09:15:00', 599.00);
-
--- 查询优势：自动分区裁剪
-SELECT * FROM sales_auto_partition 
-WHERE sale_time >= '2024-06-19'  -- 自动转换为分区条件
-  AND customer_id = 5001;
-```
-
-### 复杂业务逻辑封装

-
-## 使用限制和避坑指南
-
-### 关键限制
-
-#### 1. 条件表达式限制
-
-```sql
--- ❌ 错误：使用CASE WHEN表达式（不支持）
-CREATE TABLE wrong_table (
-    score INT,
-    grade STRING GENERATED ALWAYS AS (
-        CASE 
-            WHEN score >= 90 THEN 'A'
-            WHEN score >= 80 THEN 'B'
-            ELSE 'C'
-        END
-    )
-);
-
--- ✅ 正确做法：使用if()函数嵌套
-CREATE TABLE correct_table (
-    score INT,
-    grade STRING GENERATED ALWAYS AS (
-        if(score >= 90, 'A',
-           if(score >= 80, 'B', 'C'))
-    )
-);
-```
-
-#### 2. 函数支持限制
-
-```sql
--- ❌ 常见错误：使用不支持的函数
-CREATE TABLE wrong_functions (
-    id INT,
-    created_at TIMESTAMP_LTZ GENERATED ALWAYS AS (current_timestamp()),  -- 非确定性
-    random_val DOUBLE GENERATED ALWAYS AS (random()),                    -- 非确定性
-    name_cap STRING GENERATED ALWAYS AS (initcap('test'))               -- 函数不存在
-);
-
--- ✅ 正确做法：使用支持的确定性函数
-CREATE TABLE correct_functions (
-    id INT,
-    input_time TIMESTAMP_LTZ,
-    hour_part INT GENERATED ALWAYS AS (hour(input_time)),
-    formatted STRING GENERATED ALWAYS AS (date_format(input_time, 'yyyy-MM-dd'))
-);
-```
-
-#### 3. ALTER TABLE限制
-
-```sql
--- ❌ 错误：不能在已有列上添加生成列属性
--- ALTER TABLE existing_table MODIFY COLUMN existing_col GENERATED ALWAYS AS (expression);
-
--- ✅ 正确做法：只能添加新的生成列
-ALTER TABLE existing_table ADD COLUMN 
-new_generated_col INT GENERATED ALWAYS AS (expression);
-```
-
-### 最佳实践
-
-1. **表达式设计原则**
-   * 使用if()嵌套替代CASE WHEN
-   * 使用简单确定性函数
-   * 确保表达式性能良好
-   * 注意返回类型与列类型匹配
-
-2. **命名规范建议**
-   ```sql
-   CREATE TABLE naming_example (
-       raw_timestamp TIMESTAMP_LTZ,           -- 基础列：原始数据
-       gen_hour INT GENERATED ALWAYS AS (hour(raw_timestamp)),              -- 生成列：gen_前缀
-       gen_date STRING GENERATED ALWAYS AS (date_format(raw_timestamp, 'yyyy-MM-dd'))
-   );
-   ```
-
-3. **函数使用建议**
-   * 验证函数支持：新函数使用前先创建测试表验证
-   * 使用try\_cast进行安全转换
-   * 注意函数语法差异
-

-
-## 实战迁移案例
-
-### 案例1：电商订单表迁移（MySQL → 云器Lakehouse）
-
-#### 原始MySQL表结构
-
-```sql
--- 原MySQL表：手动计算衍生字段
-CREATE TABLE orders_mysql (
-    order_id INT PRIMARY KEY,
-    customer_id INT,
-    order_time TIMESTAMP,
-    amount DECIMAL(10,2),
-    order_date DATE,           -- 手动计算
-    order_hour INT,           -- 手动计算
-    amount_level VARCHAR(10)  -- 手动计算
-);
-```
-
-#### 云器Lakehouse生成列方案
-
-```sql
--- 迁移后的设计
-CREATE TABLE orders_lakehouse (
-    order_id INT,
-    customer_id INT,
-    order_time TIMESTAMP_LTZ,
-    amount DOUBLE,
-    -- 生成列：自动计算，确保一致性
-    order_date STRING GENERATED ALWAYS AS (date_format(order_time, 'yyyy-MM-dd')),
-    order_hour INT GENERATED ALWAYS AS (hour(order_time)),
-    amount_level STRING GENERATED ALWAYS AS (
-        if(amount >= 1000, 'HIGH',
-           if(amount >= 500, 'MEDIUM', 'LOW'))
-    )
-) PARTITIONED BY (order_date);
-
--- 应用程序只需插入基础字段
-INSERT INTO orders_lakehouse (order_id, customer_id, order_time, amount) VALUES 
-(1001, 5001, TIMESTAMP '2024-06-19 14:30:00', 299.99);
-```
-
-#### 迁移效果对比
-
-* **查询速度**：提升60%（避免重复计算）
-* **开发效率**：提升80%（无需手动计算逻辑）
-* **数据一致性**：提升100%（统一计算逻辑）
-
-***
-
-## 性能优化建议
-
-### 索引策略
-
-* 为经常用于WHERE条件和GROUP BY的生成列创建索引
-* 时间维度的生成列通常需要索引
-* 监控生成列的基数，基数过低的生成列不适合创建索引
-
-### 表达式优化
-
-* 表达式设计要简洁高效
-* 避免过于复杂的嵌套if()语句
-* 复杂逻辑可以拆分为多个简单的生成列
-* 建议每张表的生成列数量控制在5-10个以内
-
-### 查询优化
-
-* 使用生成列而不是重新计算原表达式
-* 确保分区值分布均匀，避免数据倾斜
-* 定期检查生成列的查询性能表现
-
-***
-
-## 故障排查手册
-
-### 基础功能验证
-
-```sql
--- 1. 表结构验证
-DESCRIBE TABLE your_table_name;
--- 检查：生成列是否出现在列表中，数据类型是否正确
-
--- 2. 基本插入测试
-INSERT INTO your_table_name (base_column1, base_column2) VALUES (test_value1, test_value2);
--- 检查：是否能成功插入数据
-
--- 3. 生成列值验证
-SELECT base_column1, base_column2, generated_column1, generated_column2 FROM your_table_name;
--- 检查：生成列的值是否符合预期表达式结果
-
--- 4. 插入保护机制验证
--- INSERT INTO your_table_name (base_column1, generated_column1) VALUES (value1, invalid_value);
--- 检查：是否正确报错"cannot insert or update generated column"
-```
-
-### 高级功能验证
-
-```sql
--- 5. 分区生成列验证（如果使用）
-SHOW PARTITIONS your_partitioned_table;
--- 检查：分区是否按生成列的值正确创建
-
--- 6. 复杂表达式验证
-SELECT generated_column, 
-       manual_calculation_expression,  -- 手动计算作为对比
-       if(generated_column = manual_calculation_expression, 'MATCH', 'MISMATCH') as validation
-FROM your_table_name;
--- 检查：生成列值与手动计算是否一致
-```
-
-### 常见问题排查
-
-#### 问题1：CASE WHEN表达式不支持
-
-**解决方案**：改用if()嵌套
-
-```sql
--- 原CASE WHEN逻辑：
--- CASE WHEN score >= 90 THEN 'A' WHEN score >= 80 THEN 'B' ELSE 'C' END
-
--- 改为if()嵌套：
-if(score >= 90, 'A', if(score >= 80, 'B', 'C'))
-```
-
-#### 问题2：函数不支持
-
-**解决方案**：使用支持的函数替代
-
-```sql
--- log(x) -> log10(x)
--- initcap(str) -> 使用upper/lower组合
--- CASE WHEN -> if()嵌套
-```

-
-* 部署地理信息函数所需的 JAR 包
-* 创建外部函数连接
-* 批量创建常用的地理信息函数
-* 在实际场景中使用这些函数，例如：
-  * 地理围栏分析：判断门店是否在其对应的服务区域内 ![](.topwrite/assets/geo4.jpeg =774)
-  * 区域统计分析：统计各服务区域内的门店分布情况 ![](.topwrite/assets/geo5.jpeg =757)
-
-> **Esri Geometry**：**esri-geometry-api** 和 **spatial-sdk-hive** 是 Esri 公司开源的地理计算库，在大数据领域应用极其广泛。
->
-> **核心优势**：
->
-> * **行业标准**：Esri 作为 GIS 领导者，其几何算法库已成为事实标准
-> * **功能完整**：支持 OGC 全部标准，包括点、线、面等几何类型及空间运算
-> * **应用场景**：物流配送、LBS 服务、商圈分析、城市规划
->
-> 通过集成 Esri 公司开源的地理计算库，Lakehouse 提供了标准化的地理数据处理能力
-
-## 前置条件
-
-* Lakehouse 环境已就绪
-* 具有创建外部函数和 API CONNECTION 的权限
-
-## 第一步：准备 JAR 包
-
-### 1.1 下载所需 JAR 包
-
-从 Esri 官方仓库下载以下两个 JAR 包：
-
-```
-# ESRI Geometry API
-wget https://github.com/Esri/geometry-api-java/releases/download/v2.2.0/esri-geometry-api-2.2.0.jar
-
-# Spatial Framework for Hadoop
-wget https://github.com/Esri/spatial-framework-for-hadoop/releases/download/v2.2.0/spatial-sdk-hive-2.2.0.jar
-```
-
-### 1.2 上传 JAR 包到 USER VOLUME
-
-将下载的 JAR 包上传到 Lakehouse 的 USER VOLUME（上传操作仅支持在 Lakehouse 客户端（如 [SQLLine](connect-with-cli.md)）中执行，不支持在 Lakehouse Studio 中执行）：
-
-```
-PUT '/Users/derekmeng/Downloads/esri-geometry-api-2.2.0.jar' to USER VOLUME;
-PUT '/Users/derekmeng/Downloads/spatial-sdk-hive-2.2.0.jar' to USER VOLUME;
-```
-
-## 第二步：创建 API Connection
-
-如果还没有合适的 API Connection，需要先创建一个。本例使用阿里云函数计算，详细步骤请参考：[创建 API CONNECTION](create-api-connection.md)
-
-```
-CREATE API CONNECTION fc_api_conn
-TYPE cloud_function
-  provider = 'aliyun'
-  region = 'cn-shanghai'
-  role_arn = 'acs:ram::122280886xxxxxxx:role/functionrole'
-  namespace = 'default'
-  code_bucket = '[bucket_name]';
-```
-
-可以通过 `show connections` 查看连接。
-
-## 第三步：批量创建地理信息函数
-
-### 3.1 创建常用的地理信息函数
-
-以下是生产环境中最常用的地理信息函数创建脚本，详细信息请参考创建外部函数（[CREATE EXTERNAL FUNCTION](CREATE_EXTERNATL_FUNCTION.md)）：

-
-## 第四步：创建测试数据
-
-为了验证函数功能，创建包含地理信息的测试表：
-
-```
--- 创建门店位置表
-CREATE TABLE IF NOT EXISTS store_locations (
-    store_id INT,
-    store_name STRING,
-    location STRING,  -- WKT 格式的点
-    city STRING,
-    store_type STRING
-);
-
--- 创建服务区域表
-CREATE TABLE IF NOT EXISTS service_areas (
-    area_id INT,
-    area_name STRING,
-    boundary STRING,  -- WKT 格式的多边形
-    area_type STRING,
-    city STRING
-);
-
--- 插入示例门店数据
-INSERT INTO store_locations VALUES 
-(1, '北京王府井店', 'POINT(116.410 39.914)', '北京', '旗舰店'),
-(2, '北京三里屯店', 'POINT(116.454 39.934)', '北京', '标准店'),

-```
-
-## 第五步：生产场景验证
-
-### 场景 1：地理围栏分析——判断门店是否在服务区域内
-
-这是最常见的应用场景，用于判断用户、门店或设备是否在指定的服务范围内。
-
-```
--- 查询哪些门店在各个服务区域内
-SELECT 
-    s.store_name,
-    s.city as store_city,
-    a.area_name,
-    a.area_type
-FROM 
-    store_locations s
-    JOIN service_areas a
-    ON public.ST_Contains(
-        public.ST_GeomFromText(a.boundary), 
-        public.ST_GeomFromText(s.location)
-    ) = true
-ORDER BY a.area_name, s.store_name;
-
--- 统计每个服务区域内的门店数量
-SELECT 
-    a.area_name,
-    a.area_type,
-    COUNT(s.store_id) as store_count,
-    COLLECT_LIST(s.store_name) as stores_in_area
-FROM 
-    service_areas a
-    LEFT JOIN store_locations s
-    ON public.ST_Contains(
-        public.ST_GeomFromText(a.boundary), 
-        public.ST_GeomFromText(s.location)
-    ) = true
-GROUP BY a.area_name, a.area_type
-ORDER BY store_count DESC;
-```
-
-### 场景 2：最近邻查询——查找最近的门店
-
-用于为用户推荐最近的服务点，或进行资源分配。
-
-```
--- 查找距离指定位置最近的3家门店
-WITH user_location AS (
-    SELECT public.ST_Point(116.397, 39.908) as location  -- 北京天安门位置
-)
-SELECT 
-    s.store_name,
-    s.city,
-    s.store_type,
-    public.ST_Distance(
-        u.location,
-        public.ST_GeomFromText(s.location)
-    ) as distance_degrees,
-    -- 粗略转换为公里（1度约等于111公里）
-    public.ST_Distance(
-        u.location,
-        public.ST_GeomFromText(s.location)
-    ) * 111 as distance_km
-FROM 
-    store_locations s
-    CROSS JOIN user_location u
-ORDER BY distance_degrees
-LIMIT 3;
-```
-
-### 场景 3：缓冲区分析——创建配送范围
-
-为每个门店创建配送范围，用于服务范围规划。
-
-```
--- 为旗舰店创建5公里配送范围（约0.045度）
-SELECT 
-    store_name,
-    city,
-    location as original_location,
-    public.ST_Buffer(
-        public.ST_GeomFromText(location),
-        0.045  -- 约5公里
-    ) as delivery_area
-FROM 
-    store_locations
-WHERE 
-    store_type = '旗舰店';
-
--- 查询某个点是否在任意旗舰店的配送范围内
-WITH delivery_zones AS (
-    SELECT 
-        store_name,
-        public.ST_Buffer(
-            public.ST_GeomFromText(location),
-            0.045
-        ) as delivery_area
-    FROM 
-        store_locations
-    WHERE 
-        store_type = '旗舰店'
-),
-test_point AS (
-    SELECT public.ST_Point(116.420, 39.920) as location  -- 测试点
-)
-SELECT 
-    d.store_name,
-    CASE 
-        WHEN public.ST_Contains(d.delivery_area, t.location) = true 
-        THEN '在配送范围内'
-        ELSE '不在配送范围内'
-    END as delivery_status
-FROM 
-    delivery_zones d
-    CROSS JOIN test_point t;
-```
-
-### 场景 4：区域统计分析
-
-统计各个区域的业务指标，用于商业分析。
-
-```
--- 创建销售数据表
-CREATE TABLE IF NOT EXISTS store_sales (
-    store_id INT,
-    sales_amount DECIMAL(10,2),
-    sales_date DATE
-);
-
--- 插入示例销售数据
-INSERT INTO store_sales VALUES 
-(1, 125000.50, '2024-06-01'),
-(2, 98000.00, '2024-06-01'),
-(3, 156000.75, '2024-06-01'),
-(4, 87000.25, '2024-06-01'),
-(5, 76000.00, '2024-06-01'),
-(6, 134000.80, '2024-06-01'),
-(7, 145000.60, '2024-06-01'),
-(8, 93000.40, '2024-06-01');
-
--- 按服务区域统计销售额
-SELECT 
-    a.area_name,
-    a.area_type,
-    COUNT(DISTINCT s.store_id) as store_count,
-    SUM(sales.sales_amount) as total_sales,
-    AVG(sales.sales_amount) as avg_sales_per_store
-FROM 
-    service_areas a
-    LEFT JOIN store_locations s
-    ON public.ST_Contains(
-        public.ST_GeomFromText(a.boundary), 
-        public.ST_GeomFromText(s.location)
-    ) = true
-    LEFT JOIN store_sales sales
-    ON s.store_id = sales.store_id
-GROUP BY a.area_name, a.area_type
-ORDER BY total_sales DESC;
-```
-
-### 场景 5：坐标提取与转换
-
-提取和转换坐标信息，用于与其他系统集成。
-
-```
--- 提取所有门店的经纬度坐标
-SELECT 
-    store_id,
-    store_name,
-    city,
-    public.ST_X(public.ST_GeomFromText(location)) as longitude,
-    public.ST_Y(public.ST_GeomFromText(location)) as latitude,
-    location as wkt_format
-FROM 
-    store_locations
-ORDER BY city, store_name;
-
--- 创建点并立即提取坐标（用于数据验证）
-SELECT 
-    public.ST_X(public.ST_Point(116.397, 39.908)) as x_coord,
-    public.ST_Y(public.ST_Point(116.397, 39.908)) as y_coord;
-```
-
-## 性能优化建议
-
-### 1. 使用物化视图缓存几何体转换结果
-
-```
--- 创建物化视图，预先转换 WKT 为二进制几何体
-CREATE MATERIALIZED VIEW mv_store_locations AS
-SELECT 
-    store_id,
-    store_name,
-    location as location_wkt,
-    public.ST_GeomFromText(location) as location_geom,
-    city,
-    store_type
-FROM 
-    store_locations;
-
--- 使用物化视图进行查询（性能更好）
-SELECT 
-    s.store_name,
-    a.area_name
-FROM 
-    mv_store_locations s
-    JOIN service_areas a
-    ON public.ST_Contains(
-        public.ST_GeomFromText(a.boundary), 
-        s.location_geom
-    ) = true;
-```
-
-### 2. 批量处理地理数据
-
-```
--- 批量判断多个点是否在区域内
-WITH test_points AS (
-    SELECT 1 as id, 'POINT(116.400 39.910)' as location
-    UNION ALL
-    SELECT 2, 'POINT(121.470 31.230)'
-    UNION ALL
-    SELECT 3, 'POINT(114.060 22.540)'
-)
-SELECT 
-    p.id,
-    p.location,
-    a.area_name,
-    public.ST_Contains(
-        public.ST_GeomFromText(a.boundary),
-        public.ST_GeomFromText(p.location)
-    ) as is_inside
-FROM 
-    test_points p
-    CROSS JOIN service_areas a
-WHERE 
-    public.ST_Contains(
-        public.ST_GeomFromText(a.boundary),
-        public.ST_GeomFromText(p.location)
-    ) = true;
-```
-
-## 注意事项
-
-1.  **坐标系**：默认使用 WGS84 坐标系（经纬度），距离单位为度。
-
-2.  **精度说明**：基于经纬度（WGS84）的距离计算是球面近似值，精确计算通常需要投影转换。
-
-3.  **性能考虑**：
-    * 大数据量查询时，可先用边界框（Envelope）进行粗筛。
-    * 频繁使用的几何体转换结果建议缓存。
-    * 复杂多边形运算比简单点运算消耗更多计算资源。
-
-## 故障排查
-
-### 常见错误及解决方案
-
-1. **函数未找到错误**
-
-   ```
-   错误: function not found - ST_Contains解决: 使用 public.ST_Contains
-   ```
-
-2. **几何体格式错误**
-
-   ```
-   错误: Invalid WKT format ; 解决: 检查 WKT 格式是否正确，多边形必须闭合
-   ```
-
-3. **JAR 包路径错误**
-
-   ```
-   错误: Cannot find jar file, 解决: 使用 LIST USER VOLUME 确认文件路径
-   ```

-# 通过样例数据集开始TPCH查询
-
-## 概述
-
-通过本教程，您将了解如何利用 Lakehouse 平台内置的样例数据集，无需提前准备数据即可快速使用 SQL 进行查询分析，以评估 SQL 功能及性能。
-
-> 本教程借助 Lakehouse Tutorial，提供了在线教程指南以及脚本导入功能。您可以在登录 Lakehouse Web 控制台后，通过 Lakehouse Tutorial 入口进入教程，并根据在线指南引导完成教程。
-> ![](.topwrite/assets/image_1736854694431.png)
-
-### 导入脚本
-
-打开控制台 Tutorial 页面中的“Lakehouse 教程”，选择“使用样例数据快速开始查询分析”课程。根据页面提示导入本次课程需要的脚本文件。
-
-在“开发”模块查看“Tutorial_Run_TPCH_Queries_USING_SQL”目录。
-![](.topwrite/assets/image_1725286019515.png)
-
-### 样例数据集
-
-样例数据集由云器平台通过名称为 CLICKZETTA_SAMPLE_DATA 的数据集以共享方式开放给所有账户查询。本教程将以其中的 TPC-H 100GB 数据集为例，介绍如何在 Lakehouse 中快速完成 TPC-H 测试集的查询测试，评估处理性能。
-
-### 教程步骤
-
-1.  **环境准备**：通过样例数据集检查原始数据，创建测试使用的计算集群。
-2.  **发起查询**：使用 Studio Web 环境创建 SQL 查询完成 22 个 TPC-H SQL 查询。
-3.  **变更集群大小**：调整集群大小，扩大至之前集群大小的 2 倍。
-4.  **发起查询**：使用调整大小后的集群再次完成 22 个 TPC-H SQL 查询。
-5.  **观察不同集群规格下查询时延的变化**：
-6.  **清理环境**：删除测试使用的计算集群。
-
-通过以上步骤，您将能够评估不同集群规格下 SQL 查询的性能表现。
-
-## 准备工作
-
-首先，登录 Lakehouse Web 控制台并进入指定的工作空间后，可访问数据模块，检查数据管理下的数据对象列表中“clickzetta_sample_data.tpch_100g”下的相关表是否存在。
-![](.topwrite/assets/image_1716285499384.png)
-
-其次，我们将为本次测试临时创建一个独立计算集群用于查询分析。您可以通过访问 Lakehouse Web 控制台的“计算 → 集群”菜单，通过页面向导新建集群。
-![](.topwrite/assets/tpch_100g_vc.png)
-
-同时，您也可以通过 SQL 命令来创建集群。通过 SQL 命令操作时，您可以不离开 SQL 开发上下文，在 Ad-hoc 或者 ETL 开发过程中通过 SQL 命令控制集群创建、扩/缩容、暂停/恢复、销毁等动作，往往可以提高计算资源的操作效率。
-
-本教程通过在“开发”模块运行 [Tutorials/Tutorial_Run_TPCH_Queries_USING_SQL/Step01.Preparation] SQL 脚本任务，创建分析 TPC-H 数据集所需使用的计算集群。
-![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tu_tpch_vc01.png?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=1880885164\&Signature=wYmSy3IVRKBT7mWtGhuKwT%2BwufQ%3D)
-
-## 对样例数据进行TPC-H的查询
-
-在“开发”模块打开 [Tutorials/Tutorial_Run_TPCH_Queries_USING_SQL/Step02.Run_TPCH_Queries] SQL 脚本文件，将看到 TPC-H 的 22 个查询语句已录入。在[集群]下拉列表中选择刚才创建的测试集群，然后选中任务中的全部脚本，点击[运行]按钮进行串行查询。
-![](.topwrite/assets/image_1725354834261.png)
-
-执行完毕后，可通过当前 SQL Editor 的运行历史查看本次任务的运行耗时。
-
-如果您希望进行性能测试，可连续执行 2 次以上的查询，以便计算集群能够充分缓存（Cache）数据，发挥最佳性能。以下是第二次运行，计算集群缓存（Cache）数据后的运行结果，较第一次无缓存（Cache）时性能有明显提升。
-![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tu_tpch_run_queries2.png?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=1880886165\&Signature=XHaygkpuFRtqy%2FG1EExOjIfq7vw%3D)
-
-如需查看 22 个查询中每个查询的执行详情，可访问“计算 → 作业历史”，根据查询标签“tpch100g_benchmark”对查询历史进行过滤后查看。
-
-![](.topwrite/assets/image_1716285600039.png)
-
-## 扩大集群规格后查询
-
-通过“计算 → 集群”管理页面，您可以对刚才创建的测试集群修改规格大小，从 Large 修改至 XLarge。XLarge 规格大小为 Large 的 2 倍。
-
-> 注：计算集群的 `vcluster_size` 参数同时支持以 T-shirt size（XSMALL、SMALL、Large 等）和以数字（1, 2, 4, 16 等）表达的方式，以提供更丰富的计算集群规格，满足不同场景的需要。更多信息详见：[计算集群规格代码变更说明](vcluster_size_description.md)
-
-
-![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tu_tpch_resize_vc.png?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=1880886486\&Signature=MJGwOtPq%2BHpD5E1WsHu1iyGrDnQ%3D)
-
-或者在 SQL 脚本中执行以下命令进行修改：
-
-```
--- 修改集群大小
-alter vcluster TPCH_100GB SET VCLUSTER_SIZE = 'XLARGE';
-```
-
-修改后，使用调整大小后的集群再次进行查询测试。
-![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tu_tpch_round2.png?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=1880886763\&Signature=UCaQAhoOLbeCKPrNUz22TVfAXNs%3D)
-新扩容的计算节点充分缓存（Cache）数据后，性能会继续提升。
-通过作业的运行时间可以观察到，对于相同的数据规模和查询任务，扩大计算集群规格后，任务的总体运行时间大为缩短。两次执行后，随着数据被缓存，查询性能能得到提升。
-
-## 环境清理
-
-打开“开发”模块 [Tutorial_Run_TPCH_Queries_USING_SQL/Step03.Clean_Up] SQL 脚本文件，执行脚本即可删除本教程的测试集群。

-# 使用虚拟集群加工和分析数据
-
-## 教程概述
-
-通过本教程，您将了解到如何使用虚拟集群（Virtual Cluster）对纽约出租车公开数据集 Fhvhv trips 原始数据进行清洗转换、聚合加工，并对结果数据进行多并发查询。
-
-教程案例如下图所示：
-![](.topwrite/assets/image_1714992137097.png)
-
-本教程包含以下步骤：
-
-* 环境准备：通过样例数据集检查原始数据，创建计算集群和目标 Schema
-* 数据转换：通过通用型集群清洗、聚合数据用于后续分析
-* Ad-hoc分析：使用Studio Web环境进行单并发SQL查询分析
-* 并发分析：通过Python任务模拟来自Dashboard的连续多并发查询
-
-### 入门知识
-
-什么是虚拟计算集群（Virtual Cluster）？
-
-虚拟计算集群（Virtual Cluster，简称 VC 或集群）是云器 Lakehouse 提供数据处理和分析的计算资源对象。虚拟计算集群提供在Lakehouse中执行SQL作业所需的CPU、内存、本地临时存储（SSD介质）等资源。集群具备快速创建/销毁、扩容/缩容、暂停/恢复等特点，按照资源规格大小以及使用时长进行收费，暂停或删除后不产生费用。
-
-虚拟计算集群针对 ETL 和分析场景，提供通用型和分析型两种集群类型，以满足不同负载之间的隔离和优化需求。
-
-如下图所示：
-![](.topwrite/assets/image_1714992266569.png)
-建议使用通用型集群进行 ETL 数据加工，使用分析型集群进行查询分析或支持数据产品应用。通用型集群支持纵向伸缩，满足不同规模的 ETL Pipeline 任务需要。分析型集群支持集群内多副本（Replica）的横向伸缩，以满足并发查询的弹性需求。
-
-本教程将分别使用通用型集群进行数据清洗转换，使用分析型集群进行低延迟的并发分析。
-
-### 教程目标
-
-* 创建和使用虚拟计算集群用于不同业务负载
-* 了解和使用分析型集群的弹性并发功能
-
-## Step01 检查原始数据
-
-1. 创建虚拟集群
-
-分别创建通用型（GENERAL PURPOSE）和分析型（ANALYTICS）集群，用于 ETL 加工和查询分析，实现负载隔离。
-
-```sql
--- 1.1 创建面向ETL处理的虚拟集群
-CREATE VCLUSTER ETL_VC 
-VCLUSTER_SIZE = MEDIUM 
-VCLUSTER_TYPE = GENERAL 
-AUTO_SUSPEND_IN_SECOND = 60 
-AUTO_RESUME = TRUE;
-
--- 1.2 创建面向BI分析的虚拟集群，设置弹性并发以支持多并发查询
-CREATE VCLUSTER REPORTING_VC 
-VCLUSTER_SIZE = XSMALL 
-VCLUSTER_TYPE = ANALYTICS
-MIN_REPLICAS = 1
-MAX_REPLICAS = 4
-MAX_CONCURRENCY = 8
-AUTO_SUSPEND_IN_SECOND = 300 
-AUTO_RESUME = TRUE ;
-
--- 1.3 查看集群资源
-show  vclusters ;
-
--- 1.4 切换当前Session下使用的虚拟集群,要和执行的SQL一起选中执行才会生效
-USE VCLUSTER REPORTING_VC;
-```
-
-![](.topwrite/assets/image_1714992453071.png)
-
-> 注：计算集群的 `vcluster_size` 参数同时支持 T-shirt size（XSMALL、SMALL、LARGE 等）和数字（1, 2, 4, 16 等）两种表达方式，以提供更丰富的计算集群规格，满足不同场景的需要。更多信息详见：[计算集群规格代码变更说明](vcluster_size_description.md)
-
-^
-
-2. 查看公共数据集中的原始数据
-
-2.1 查看原始数据的字段信息。
-
-```sql
---Describes New York City For-Hire-Vehicle trips. 
-desc clickzetta_sample_data.nyc_taxi_tripdata.fhvhv_tripdata;
-```
-
-![](.topwrite/assets/image_1714992471693.png)
-
-2.2 预览数据明细
-
-```sql
---Sample Of Trip Record Data
-select * from clickzetta_sample_data.nyc_taxi_tripdata.fhvhv_tripdata limit 10;
-```
-
-![](.topwrite/assets/image_1714992501025.png)
-
-2.3 查看数据集的记录数
-
-```sql
---1.49 billion rows
-select count(*) from clickzetta_sample_data.nyc_taxi_tripdata.fhvhv_tripdata;
-```
-
-## Step02 使用通用型集群清洗转换数据
-
-1. 指定使用 `ETL_VC` 进行数据加工，同时创建目标表所在的 Schema
-
-```sql
---要和执行的SQL一起选中执行才会生效
-use vcluster ETL_VC;
-create schema tutorial;
-use tutorial;
-```
-
-2. 通过 CTAS 对原始数据集进行清洗转换并写入新表
-
-```sql
---2.对原始数据集进行清洗转换
-CREATE table tutorial.int_fhvhv_tripdata
-as
-SELECT
-  hvfhs_license_num,
-  CASE 
-    WHEN hvfhs_license_num = 'HV0002' THEN 'juno'
-    WHEN hvfhs_license_num = 'HV0003' THEN 'uber'
-    WHEN hvfhs_license_num = 'HV0004' THEN 'via'
-    WHEN hvfhs_license_num = 'HV0005' THEN 'lyft'
-    ELSE null
-  END AS company,
-  ltrim(rtrim(upper(dispatching_base_num))) dispatching_base_num,
-  ltrim(rtrim(upper(originating_base_num))) originating_base_num,
-  request_datetime,
-  on_scene_datetime,
-  pickup_datetime,
-  dropoff_datetime,
-  PULocationID,
-  DOLocationID,
-  trip_miles,
-  trip_time,
-  base_passenger_fare,
-  tolls,
-  bcf,
-  sales_tax,
-  congestion_surcharge,
-  airport_fee,
-  tips,
-  driver_pay,
-  CASE
-    WHEN shared_request_flag = 'Y' THEN true
-    WHEN shared_request_flag IN ('N', ' ') THEN false
-    ELSE null
-  END AS shared_request_flag,
-  CASE
-    WHEN shared_match_flag = 'Y' THEN true
-    WHEN shared_match_flag IN ('N', ' ') THEN false
-    ELSE null
-  END AS shared_match_flag,
-  CASE
-    WHEN access_a_ride_flag = 'Y' THEN true
-    WHEN access_a_ride_flag IN ('N', ' ') THEN false
-    ELSE null
-  END AS access_a_ride_flag,
-  CASE
-    WHEN wav_request_flag = 'Y' THEN true
-    WHEN wav_request_flag IN ('N', ' ') THEN false
-    ELSE null
-  END AS wav_request_flag,
-  CASE
-    WHEN wav_match_flag = 'Y' THEN true
-    WHEN wav_match_flag IN ('N', ' ') THEN false
-    ELSE null
-  END AS wav_match_flag
-FROM clickzetta_sample_data.nyc_taxi_tripdata.fhvhv_tripdata;
-```
-
-验证加工后的数据
-
-```sql
-SELECT * FROM tutorial.int_fhvhv_tripdata LIMIT 10;
-```
-
-![](.topwrite/assets/image_1714992818566.png)
-
-3. 对清洗后的数据按照分析主题分别进行聚合计算，生成用于分析的数据表。
-
-```sql
---Scenario 1: Analyze taxi trip patterns by time of day
-CREATE table tutorial.mart_trips_pattern_by_time
-AS
-SELECT
-  EXTRACT(HOUR FROM pickup_datetime) AS hour,
-  COUNT(*) AS trip_count
-FROM tutorial.int_fhvhv_tripdata
-GROUP BY hour;
-
---Scenario 2: Analyze taxi trip patterns by day of the week
-CREATE table tutorial.mart_trips_pattern_by_dayofweek
-AS
-SELECT
-  EXTRACT(DAY FROM pickup_datetime) AS day_of_week,
-  COUNT(*) AS trip_count
-FROM tutorial.int_fhvhv_tripdata
-GROUP BY day_of_week;
-
---Scenario 3: Analyze taxi trip patterns by pickup location
-CREATE table tutorial.mart_trips_pattern_by_pickup_location
-AS
-SELECT
-  PULocationID,
-  COUNT(*) AS trip_count
-FROM tutorial.int_fhvhv_tripdata
-GROUP BY PULocationID;
-
---Scenario 4: Analyze taxi trip patterns by dropoff location
-CREATE table tutorial.mart_trips_pattern_by_dropoff_location
-AS
-SELECT
-  DOLocationID,
-  COUNT(*) AS trip_count
-FROM tutorial.int_fhvhv_tripdata
-GROUP BY DOLocationID;
-
---Scenario 5:Trips per day
-CREATE table tutorial.mart_trips_per_day
-AS
-SELECT
-  pickup_datetime::date AS date,
-  sum(trip_miles) AS trip_miles
-FROM tutorial.int_fhvhv_tripdata
-GROUP BY date;
-
---Scenario 6:Total driver pay per company
-CREATE table tutorial.mart_trips_driver_pay_per_company
-AS
-SELECT
-  CONCAT(YEAR(pickup_datetime), '-', MONTH(pickup_datetime)) AS year_month,
-  company,
-  sum(driver_pay) AS driver_pay
-FROM tutorial.int_fhvhv_tripdata
-GROUP BY year_month,company;
-```
-
-检查数据对象是否创建成功。
-
-```sql
---检查新创建数据模型的状态
-show tables in tutorial;
-```
-
-![](.topwrite/assets/image_1714992844915.png)
-
-```sql
---检查新创建数据模型的数据
-SELECT * FROM tutorial.mart_trips_driver_pay_per_company
-WHERE substr(year_month,0,4)='2021'
-ORDER BY year_month ASC;
-```
-
-![](.topwrite/assets/image_1714992852747.png)
-
-## Step03 使用分析型集群单并发查询
-
-1. 切换当前 Session 使用的虚拟集群为 REPORTING_VC。
-
-```sql
--- 1.使用分析型VC进行加速查询分析，要和执行的SQL一起选中执行才会生效
-USE VCLUSTER REPORTING_VC;
---设置查询作业标签，以便检索过滤，要和执行的SQL一起选中执行才会生效
-SET QUERY_TAG = 'Tutorial02';
-```
-
-2. 串行执行 6 个业务分析查询。
-
-```sql
---Scenario 1: Analyze taxi trip patterns by time of day
-SELECT * FROM tutorial.mart_trips_pattern_by_time
-ORDER BY HOUR ASC;
-
---Scenario 2: Analyze taxi trip patterns by day of the week
-SELECT * FROM tutorial.mart_trips_pattern_by_dayofweek
-ORDER BY day_of_week ASC;
-
---Scenario 3: Analyze taxi trip patterns by pickup location
-SELECT * FROM tutorial.mart_trips_pattern_by_pickup_location
-ORDER BY trip_count DESC
-LIMIT 10;
-
---Scenario 4: Analyze taxi trip patterns by dropoff location
-SELECT * FROM tutorial.mart_trips_pattern_by_dropoff_location
-ORDER BY trip_count DESC
-LIMIT 10;
-
---Scenario 5:Trips per day
-SELECT * FROM tutorial.mart_trips_per_day
-WHERE CONCAT(YEAR(date) , MONTH(date)) = '202110'
-ORDER BY date;
-
---Scenario 6:Total driver pay per company
-SELECT * FROM tutorial.mart_trips_driver_pay_per_company
-WHERE substr(year_month,0,4)='2021'
-ORDER BY year_month ASC;
-```
-
-3. 观察查询的 Latency 结果。
-
-```sql
---清除QUERY_TAG
-SET QUERY_TAG = '';
---查看运行的作业执行结果
-SHOW JOBS WHERE QUERY_TAG='Tutorial02' LIMIT 10;
-```
-
-您还可以使用 Studio 页面的作业历史功能查看查询作业的执行情况。
-![](.topwrite/assets/image_1714992890007.png)
-
-## Step04 使用Python任务并发查询
-
-通过Python任务进行并发查询测试，查看分析型集群在连续的动态并发查询下的性能表现以及弹性扩展能力。
-
-1. 在 Studio 开发模块中，创建 Python 任务。
-   ![](.topwrite/assets/image_1714992974205.png)
-
-2. 通过 Lakehouse Python SDK 编写并发测试脚本
-
-本教程的脚本实现了以下处理逻辑：
-
-* 创建 Lakehouse 服务实例连接，指定工作空间、计算集群名称。
-* 通过提交连续、梯度增加的并发查询，模拟多用户发起的 Dashboard 查询。
-* 收集并打印并发查询下的 Latency 以及计算资源的弹性扩容状态变化。
-
-```python
-# Step 04: 使用Studio Python任务进行并发查询
-# 操作步骤：
-# 1.创建Lakehouse服务实例连接，指定工作空间、计算集群名称
-# 2.通过提交连续、梯度增加并发查询来模拟多用户发起的Dashboard查询
-# 3.观察连续并发查询下，分析型计算集群的动态弹性并发能力

-
-客户端分别模拟 4、8、12、16 四轮并发查询，每轮每个并发连续提交 30 次查询。可以观察到 `reporting_vc` 会根据客户端并发度动态增加副本（Replica）数量，在用户无感知集群动态扩容的前提下，保证不同并发数量下平均时延、P95、P99、QPS 指标保持稳定。

-# GRANT TO SHARE 语句
-
-## 功能描述
-
-`GRANT TO SHARE` 语句的主要功能是将指定的表（table）或视图（view）添加到一个已存在的分享对象（share）中，并授予相应的权限。通过使用该语句，用户可以方便地对数据进行共享和管理，同时确保数据的安全性和可访问性。
-
-仅支持将表（table）或视图（view）添加到类型（kind属性）为'OUTBOUND'（对外分享）的分享对象中。其他服务实例分享进入的分享对象（share）不可添加数据对象。
-
-## 语法格式
-
-```SQL
-GRANT select, read metadata ON {TABLE <table_name> | VIEW <view_name>} TO SHARE <share_name>;
-```
-
-**参数说明**
-
-1. **share_name**：需要操作的分享对象名称。
-2. **table_name**：需要添加到分享对象中的表名称。
-3. **view_name**：需要添加到分享对象中的视图名称。
-4. **select, read metadata**：需要授予分享对象的权限点。`select` 权限允许对被分享的数据进行查询操作；`read metadata` 权限使得加入分享对象的表和视图的元数据对被分享方可见。当授予表或视图的 `read metadata` 权限时，其所属的模式（schema）的 `read metadata` 权限也将自动被授予至分享对象，以实现表和视图对被分享方的可见性。
-
-## 使用示例
-
-**示例 1：指定表进行分享**
-
-假设我们有一个名为 `share_demo` 的分享对象，以及一个名为 `share_demo_table` 的表。我们希望将 `share_demo_table` 表添加到 `share_demo` 分享对象中，并授予 `select` 和 `read metadata` 权限。可以使用以下语句实现：
-
-```SQL
-GRANT select, read metadata ON TABLE share_demo_table TO SHARE share_demo;
-```
-
-**示例 2：指定视图进行分享**
-
-在这个示例中，我们有一个名为 `share_demo` 的分享对象和一个名为 `share_demo_view` 的视图。我们希望将 `share_demo_view` 视图添加到 `share_demo` 分享对象中，并授予相应的权限。可以使用以下语句：
-
-```SQL
-GRANT select, read metadata ON VIEW share_demo_view TO SHARE share_demo;
-```
-
-**示例 3：同时分享多个表和视图**
-
-有时，我们可能需要将多个表和视图添加到分享对象中。此时需要多次执行 GRANT 语句，每个 GRANT 语句将其中一个数据对象加入到指定的 share 对象中。以下示例展示了如何将 `share_demo_table1`、`share_demo_table2` 和 `share_demo_view` 添加到 `share_demo` 分享对象中，并授予相应的权限：
-
-```SQL
-GRANT select, read metadata ON TABLE share_demo_table1, share_demo_table2 TO SHARE share_demo;
-GRANT select, read metadata ON VIEW share_demo_view TO SHARE share_demo;
-```
-
-## 注意事项
-
-1. 在执行 `GRANT TO SHARE` 语句之前，请确保分享对象（share）已经存在。
-2. 仅当您具备该对象的 select 和 read metadata 权限，并可将该权限做二次授权时，才可将该对象添加至数据分享对象中。
-3. 当分享表或视图时，请确保充分考虑数据的安全性和可访问性，以避免不必要的风险。

-4. `schemaObjectPrivileges`：在 schema 下对象的修改、查询等权限，例如 `ALTER`、`DROP`、`SELECT` 等。
-5. `role_name`：角色名称，支持自定义角色和系统默认角色。系统默认角色包括 `system_admin`、`user_admin`、`security_admin`、`audit_admin` 等。
-6. `username`：用户名称。
-7. `WITH GRANT OPTION`：表示被授权的用户可以将这些权限再授权给其他用户。
-
-## 使用示例
-
-1. 授权给用户 `uat_demo` 在 `lakehouse_public` workspace 下创建 `VIRTUAL CLUSTER` 权限：
-   ```SQL
-   GRANT CREATE VCLUSTER ON WORKSPACE lakehouse_public TO USER uat_demo;
-   ```
-
-2. 授权给用户 `uat_demo` 修改名为 `default` 的 `VIRTUAL CLUSTER` 权限：
-   ```SQL
-   GRANT ALTER VCLUSTER ON VCLUSTER default TO USER  uat_demo;
-   ```
-
-3. 授权给用户 `uat_demo` 在 `public` schema 下创建表和视图的权限：

-# GROUP BY
-
-## 概述
-
-`GROUP BY` 子句是 SQL 查询中用于数据分组和聚合分析的核心组件。通过 `GROUP BY`，可以将数据集按照指定的列或表达式进行分组，并对每个分组应用聚合函数（如 `SUM()`、`COUNT()`、`AVG()`、`MAX()`、`MIN()` 等）计算汇总值。
-
-云器 Lakehouse 完整支持标准 SQL GROUP BY 语法，并提供高级聚合能力：
-
-| 功能                | 说明         | 应用场景           |
-| ----------------- | ---------- | -------------- |
-| **标准 GROUP BY**   | 基础分组聚合     | 日常统计、基础报表      |
-| **GROUPING SETS** | 自定义多个分组集合  | 多维度业务分析        |
-| **ROLLUP**        | 层级汇总（从细到总） | 财务报表、销售层级分析    |
-| **CUBE**          | 全维度交叉分析    | BI 多维数据透视、交叉分析 |
-
-***
-
-## 语法结构
-
-```sql
-SELECT 
-    column1,
-    column2,
-    aggregate_function(column3) AS alias
-FROM table_name
-WHERE condition
-GROUP BY 
-    [ group_expression [, group_expression, ...] |
-      GROUPING SETS (grouping_set [, grouping_set, ...]) |
-      ROLLUP(expression [, expression, ...]) |
-      CUBE(expression [, expression, ...]) ]
-HAVING aggregate_condition
-ORDER BY column
-LIMIT n;
-```
-
-### 关键要点
-
-1. **SELECT 子句约束**：SELECT 列表中的非聚合列必须出现在 GROUP BY 子句中
-2. **执行顺序**：FROM → WHERE → GROUP BY → HAVING → SELECT → ORDER BY → LIMIT
-3. **HAVING 过滤**：用于过滤聚合结果，而 WHERE 过滤原始行
-4. **NULL 值处理**：NULL 被视为一个独立的分组
-

-
-## 准备测试数据
-
-本文档使用汽车经销商销售数据作为示例。创建测试视图：
-
-```sql
-CREATE OR REPLACE VIEW dealer (id, city, car_model, quantity) AS
-VALUES 
-    (100, 'Fremont', 'Honda Civic', 10),
-    (100, 'Fremont', 'Honda Accord', 15),
-    (100, 'Fremont', 'Honda CRV', 7),
-    (200, 'Dublin', 'Honda Civic', 20),
-    (200, 'Dublin', 'Honda Accord', 10),
-    (200, 'Dublin', 'Honda CRV', 3),
-    (300, 'San Jose', 'Honda Civic', 5),
-    (300, 'San Jose', 'Honda Accord', 8);
-```
-
-查看原始数据：
-
-```sql
-SELECT * FROM dealer ORDER BY id, car_model LIMIT 50;
-```
-
-**查询结果**：
-
-| id  | city     | car\_model   | quantity |
-| --- | -------- | ------------ | -------- |
-| 100 | Fremont  | Honda Accord | 15       |
-| 100 | Fremont  | Honda CRV    | 7        |
-| 100 | Fremont  | Honda Civic  | 10       |
-| 200 | Dublin   | Honda Accord | 10       |
-| 200 | Dublin   | Honda CRV    | 3        |
-| 200 | Dublin   | Honda Civic  | 20       |
-| 300 | San Jose | Honda Accord | 8        |
-| 300 | San Jose | Honda Civic  | 5        |
-
-***
-
-## 一、标准 GROUP BY
-
-### 1.1 单列分组
-
-按经销商 ID 分组，统计每个经销商的销量：
-
-```sql
-SELECT 
-    id, 
-    SUM(quantity) AS total_quantity
-FROM dealer
-GROUP BY id
-ORDER BY id
-LIMIT 50;
-```
-
-**查询结果**：
-
-| id  | total\_quantity |
-| --- | --------------- |
-| 100 | 32              |
-| 200 | 33              |
-| 300 | 13              |
-
-**业务解读**：
-
-*   经销商 100（Fremont）销售了 32 辆车
-*   经销商 200（Dublin）销售了 33 辆车
-*   经销商 300（San Jose）销售了 13 辆车
-
-***
-
-### 1.2 多列分组
-
-按城市和车型的组合进行分组统计：
-
-```sql
-SELECT 
-    id, 
-    city, 
-    SUM(quantity) AS total_quantity
-FROM dealer
-GROUP BY id, city
-ORDER BY total_quantity DESC
-LIMIT 50;
-```
-
-**查询结果**：
-
-| id  | city     | total\_quantity |
-| --- | -------- | --------------- |
-| 200 | Dublin   | 33              |
-| 100 | Fremont  | 32              |
-| 300 | San Jose | 13              |
-
-在本示例中，每个经销商 ID 对应唯一的城市，因此结果与单列分组相同。
-
-***
-
-### 1.3 使用表达式分组
-
-使用 `CASE` 表达式对销量进行分段统计：
-
-```sql
-SELECT 
-    CASE 
-        WHEN quantity < 10 THEN 'Low (< 10)'
-        WHEN quantity < 15 THEN 'Medium (10-14)'
-        ELSE 'High (>= 15)'
-    END AS sales_level,
-    COUNT(*) AS record_count,
-    SUM(quantity) AS total_quantity
-FROM dealer
-GROUP BY 
-    CASE 
-        WHEN quantity < 10 THEN 'Low (< 10)'
-        WHEN quantity < 15 THEN 'Medium (10-14)'
-        ELSE 'High (>= 15)'
-    END
-ORDER BY sales_level
-LIMIT 50;
-```
-
-**查询结果**：
-
-| sales\_level   | record\_count | total\_quantity |
-| -------------- | ------------- | --------------- |
-| High (>= 15)   | 2             | 35              |
-| Low (< 10)     | 4             | 23              |
-| Medium (10-14) | 2             | 20              |
-
-**业务解读**：
-
-* 高销量记录（≥15 辆）：2 条记录，共 35 辆
-* 低销量记录（<10 辆）：4 条记录，共 23 辆
-* 中等销量记录（10-14 辆）：2 条记录，共 20 辆
-
-***
-
-### 1.4 全局聚合（无分组）
-
-不使用 GROUP BY 时，对整个表进行全局聚合：
-
-```sql
-SELECT SUM(quantity) AS total_quantity 
-FROM dealer
-LIMIT 50;
-```
-
-**查询结果**：
-
-| total\_quantity |
-| --------------- |
-| 78              |
-
-全部 8 条记录的总销量为 78 辆。
-
-***
-
-## 二、多聚合函数组合
-
-### 2.1 常用聚合函数汇总
-
-在单次查询中使用多个聚合函数：
-
-```sql
-SELECT 
-    city,
-    COUNT(*) AS model_count,
-    SUM(quantity) AS total_quantity,
-    AVG(quantity) AS avg_quantity,
-    MAX(quantity) AS max_quantity,
-    MIN(quantity) AS min_quantity
-FROM dealer
-GROUP BY city
-ORDER BY total_quantity DESC
-LIMIT 50;
-```
-
-**查询结果**：
-
-| city     | model\_count | total\_quantity | avg\_quantity      | max\_quantity | min\_quantity |
-| -------- | ------------ | --------------- | ------------------ | ------------- | ------------- |
-| Dublin   | 3            | 33              | 11.0               | 20            | 3             |
-| Fremont  | 3            | 32              | 10.666666666666666 | 15            | 7             |
-| San Jose | 2            | 13              | 6.5                | 8             | 5             |
-
-**业务洞察**：
-
-* **Dublin**：3 个车型，平均每个车型销售 11 辆，最高单品 20 辆（Honda Civic）
-* **Fremont**：3 个车型，平均销量 10.67 辆，销量较均衡
-* **San Jose**：仅 2 个车型，平均销量 6.5 辆，市场规模最小
-
-***
-
-### 2.2 按车型统计覆盖城市数
-
-统计每个车型在多少个城市有销售：
-
-```sql
-SELECT 
-    car_model,
-    SUM(quantity) AS total_sales,
-    COUNT(DISTINCT city) AS city_count,
-    ROUND(AVG(quantity), 2) AS avg_per_dealer
-FROM dealer
-GROUP BY car_model
-ORDER BY total_sales DESC
-LIMIT 50;
-```
-
-**查询结果**：
-
-| car\_model   | total\_sales | city\_count | avg\_per\_dealer |
-| ------------ | ------------ | ----------- | ---------------- |
-| Honda Civic  | 35           | 3           | 11.67            |
-| Honda Accord | 33           | 3           | 11.00            |
-| Honda CRV    | 10           | 2           | 5.00             |
-
-**业务洞察**：
-
-* **Honda Civic**：最畅销车型，总销量 35 辆，覆盖 3 个城市，平均每地 11.67 辆
-* **Honda Accord**：总销量 33 辆，覆盖 3 个城市
-* **Honda CRV**：总销量最低，仅在 2 个城市有销售（未进入 San Jose 市场）
-
-***
-
-## 三、GROUPING SETS（自定义分组集合）
-
-### 3.1 基本概念
-
-`GROUPING SETS` 允许在一次查询中同时生成多个不同维度的分组结果。它本质上是多个 `GROUP BY` 查询通过 `UNION ALL` 组合的简写形式。
-
-**语法**：
-
-```sql
-GROUP BY GROUPING SETS (
-    (column1, column2),  -- 分组集1：按 column1 和 column2 分组
-    (column1),           -- 分组集2：仅按 column1 分组
-    ()                   -- 分组集3：全局聚合（无分组）
-)
-```
-
-***
-
-### 3.2 多维度聚合分析
-
-在一次查询中生成四个维度的统计结果：
-
-```sql
-SELECT 
-    city, 
-    car_model, 
-    SUM(quantity) AS total_quantity
-FROM dealer
-GROUP BY GROUPING SETS (
-    (city, car_model),  -- 城市+车型明细
-    (city),             -- 按城市汇总
-    (car_model),        -- 按车型汇总
-    ()                  -- 总计
-)
-ORDER BY city, car_model
-LIMIT 50;
-```
-

-**结果解读**：
-
-* **总计行**（city=NULL, car\_model=NULL）：全部销量 78 辆
-* **车型汇总行**（city=NULL, car\_model有值）：各车型跨城市总销量
-* **城市汇总行**（city有值, car\_model=NULL）：各城市跨车型总销量
-* **明细行**（city和car\_model都有值）：城市+车型组合的具体销量
-
-**等价查询**：
-
-```sql
--- GROUPING SETS 等价于以下 UNION ALL 查询
-SELECT city, car_model, SUM(quantity) FROM dealer GROUP BY city, car_model
-UNION ALL
-SELECT city, NULL, SUM(quantity) FROM dealer GROUP BY city
-UNION ALL
-SELECT NULL, car_model, SUM(quantity) FROM dealer GROUP BY car_model
-UNION ALL
-SELECT NULL, NULL, SUM(quantity) FROM dealer;
-```
-
-**性能优势**：`GROUPING SETS` 在内部只扫描一次数据，比 `UNION ALL` 更高效。
-
-***
-
-### 3.3 识别汇总层级
-
-使用 `COALESCE` 函数替换 NULL 值，使汇总行更易读：
-
-```sql
-SELECT 
-    COALESCE(city, 'All Cities') AS city,
-    COALESCE(car_model, 'All Models') AS car_model,
-    SUM(quantity) AS total_quantity
-FROM dealer
-GROUP BY ROLLUP(city, car_model)
-ORDER BY city, car_model
-LIMIT 50;
-```
-
-**查询结果**：
-
-| city       | car\_model   | total\_quantity |
-| ---------- | ------------ | --------------- |
-| All Cities | All Models   | 78              |
-| Dublin     | All Models   | 33              |
-| Dublin     | Honda Accord | 10              |
-| Dublin     | Honda CRV    | 3               |
-| Dublin     | Honda Civic  | 20              |
-| Fremont    | All Models   | 32              |
-| Fremont    | Honda Accord | 15              |
-| Fremont    | Honda CRV    | 7               |
-| Fremont    | Honda Civic  | 10              |
-| San Jose   | All Models   | 13              |
-| San Jose   | Honda Accord | 8               |
-| San Jose   | Honda Civic  | 5               |

-
-## 四、ROLLUP（层级汇总）
-
-### 4.1 基本概念
-
-`ROLLUP` 用于生成从细粒度到全局的层级汇总。对于 `ROLLUP(a, b, c)`，将生成以下分组集：
-
-* `(a, b, c)` - 最细粒度
-* `(a, b)` - 中间层级
-* `(a)` - 高层级
-* `()` - 全局汇总
-
-**等价关系**：
-
-```sql
-ROLLUP(city, car_model) 
--- 等价于
-GROUPING SETS (
-    (city, car_model),
-    (city),
-    ()
-)
-```
-
-***
-
-### 4.2 销售层级汇总
-
-生成"城市→车型"两级汇总：
-
-```sql
-SELECT 
-    city, 
-    car_model, 
-    SUM(quantity) AS total_quantity 
-FROM dealer
-GROUP BY ROLLUP(city, car_model)
-LIMIT 50;
-```
-
-**查询结果**：
-
-| city     | car\_model   | total\_quantity |
-| -------- | ------------ | --------------- |
-| Fremont  | Honda Civic  | 10              |
-| Fremont  | Honda Accord | 15              |
-| Fremont  | Honda CRV    | 7               |
-| Dublin   | Honda Civic  | 20              |
-| Dublin   | Honda Accord | 10              |
-| Dublin   | Honda CRV    | 3               |
-| San Jose | Honda Civic  | 5               |
-| San Jose | Honda Accord | 8               |
-| Fremont  | NULL         | 32              |
-| Dublin   | NULL         | 33              |
-| San Jose | NULL         | 13              |
-| NULL     | NULL         | 78              |
-
-**数据层级**：
-
-1. **明细层**（前8行）：每个城市的每种车型的销量
-2. **城市小计**（car\_model=NULL）：每个城市的总销量
-3. **总计**（city=NULL, car\_model=NULL）：所有城市的总销量
-
-***
-
-### 4.3 使用 GROUPING() 函数标识层级
-
-`GROUPING()` 函数返回 0 或 1，用于区分真实 NULL 和聚合标记：
-
-* **返回 0**：该列参与分组，值为实际数据
-* **返回 1**：该列未参与分组，NULL 表示汇总
-
-```sql
-SELECT 
-    city,
-    car_model,
-    SUM(quantity) AS total_quantity,
-    GROUPING(city) AS city_grouping,
-    GROUPING(car_model) AS model_grouping
-FROM dealer
-GROUP BY ROLLUP(city, car_model)
-ORDER BY city_grouping, city, model_grouping, car_model
-LIMIT 50;
-```
-
-**查询结果**：
-
-| city     | car\_model   | total\_quantity | city\_grouping | model\_grouping |
-| -------- | ------------ | --------------- | -------------- | --------------- |
-| Dublin   | Honda Accord | 10              | 0              | 0               |
-| Dublin   | Honda CRV    | 3               | 0              | 0               |
-| Dublin   | Honda Civic  | 20              | 0              | 0               |
-| Dublin   | NULL         | 33              | 0              | 1               |
-| Fremont  | Honda Accord | 15              | 0              | 0               |
-| Fremont  | Honda CRV    | 7               | 0              | 0               |
-| Fremont  | Honda Civic  | 10              | 0              | 0               |
-| Fremont  | NULL         | 32              | 0              | 1               |
-| San Jose | Honda Accord | 8               | 0              | 0               |
-| San Jose | Honda Civic  | 5               | 0              | 0               |
-| San Jose | NULL         | 13              | 0              | 1               |
-| NULL     | NULL         | 78              | 1              | 1               |
-
-**GROUPING() 值解读**：
-
-* (**0, 0**)：明细数据，两列都参与分组
-* (**0, 1**)：城市小计，仅 city 参与分组
-* (**1, 1**)：全局总计，两列都不参与分组
-
-***
-
-## 五、CUBE（全维度交叉分析）
-
-### 5.1 基本概念
-
-`CUBE` 生成指定列的所有可能组合的分组集。对于 `CUBE(a, b)`，将生成 2² = 4 个分组集：
-
-* `(a, b)` - 明细
-* `(a)` - 按 a 汇总
-* `(b)` - 按 b 汇总
-* `()` - 全局汇总
-
-**等价关系**：
-
-```sql
-CUBE(city, car_model)
--- 等价于
-GROUPING SETS (
-    (city, car_model),
-    (city),
-    (car_model),
-    ()
-)
-```
-
-***
-
-### 5.2 多维交叉分析
-
-生成城市和车型的所有维度组合：
-
-```sql
-SELECT 
-    city, 
-    car_model, 
-    SUM(quantity) AS total_quantity 
-FROM dealer
-GROUP BY city, car_model WITH CUBE
-LIMIT 50;
-```
-
-**查询结果**：
-
-| city     | car\_model   | total\_quantity |
-| -------- | ------------ | --------------- |
-| Fremont  | Honda Civic  | 10              |
-| Fremont  | Honda Accord | 15              |
-| Fremont  | Honda CRV    | 7               |
-| Dublin   | Honda Civic  | 20              |
-| Dublin   | Honda Accord | 10              |
-| Dublin   | Honda CRV    | 3               |
-| San Jose | Honda Civic  | 5               |
-| San Jose | Honda Accord | 8               |
-| NULL     | Honda CRV    | 10              |
-| NULL     | Honda Civic  | 35              |
-| NULL     | Honda Accord | 33              |
-| Fremont  | NULL         | 32              |
-| Dublin   | NULL         | 33              |

-| NULL     | NULL         | 78              |
-
-**结果包含**：
-
-1. **明细行**（前8行）：城市+车型组合
-2. **车型汇总行**（city=NULL）：跨城市的车型销量
-3. **城市汇总行**（car\_model=NULL）：跨车型的城市销量
-4. **总计行**（city=NULL, car\_model=NULL）：全局总计
-
-***
-
-### 5.3 标识聚合层级
-
-使用 `CASE` 语句结合 `GROUPING()` 函数标识每行的聚合层级：
-
-```sql
-SELECT 
-    city,
-    car_model,
-    SUM(quantity) AS total_quantity,
-    CASE 
-        WHEN GROUPING(city) = 1 AND GROUPING(car_model) = 1 THEN 'Total'
-        WHEN GROUPING(city) = 0 AND GROUPING(car_model) = 1 THEN 'City Subtotal'
-        WHEN GROUPING(city) = 1 AND GROUPING(car_model) = 0 THEN 'Model Subtotal'
-        ELSE 'Detail'
-    END AS aggregation_level
-FROM dealer
-GROUP BY CUBE(city, car_model)
-ORDER BY 
-    GROUPING(city),
-    GROUPING(car_model),
-    city,
-    car_model
-LIMIT 50;
-```
-
-**查询结果**：
-
-| city     | car\_model   | total\_quantity | aggregation\_level |
-| -------- | ------------ | --------------- | ------------------ |
-| Dublin   | Honda Accord | 10              | Detail             |
-| Dublin   | Honda CRV    | 3               | Detail             |
-| Dublin   | Honda Civic  | 20              | Detail             |
-| Fremont  | Honda Accord | 15              | Detail             |
-| Fremont  | Honda CRV    | 7               | Detail             |
-| Fremont  | Honda Civic  | 10              | Detail             |
-| San Jose | Honda Accord | 8               | Detail             |
-| San Jose | Honda Civic  | 5               | Detail             |
-| Dublin   | NULL         | 33              | City Subtotal      |
-| Fremont  | NULL         | 32              | City Subtotal      |
-| San Jose | NULL         | 13              | City Subtotal      |

-| NULL     | Honda CRV    | 10              | Model Subtotal     |
-| NULL     | Honda Civic  | 35              | Model Subtotal     |
-| NULL     | NULL         | 78              | Total              |
-
-此查询清晰地标识了每行数据所属的聚合层级。

-
-### 5.4 ROLLUP vs CUBE
-
-| 维度              | ROLLUP         | CUBE                |
-| --------------- | -------------- | ------------------- |
-| **生成分组集**       | 层级子集（从左到右）     | 所有可能组合              |
-| **ROLLUP(a,b**) | (a,b), (a), () | (a,b), (a), (b), () |
-| **分组数量**        | n+1（n为列数）      | 2ⁿ                  |
-| **使用场景**        | 层级报表、自上而下分析    | 多维交叉分析、BI 透视表       |
-| **性能**          | 生成分组数少，性能更优    | 生成分组数多，性能开销较大       |
-
-**选择建议**：
-
-* 需要**层级汇总**（如 地区→城市→门店）时使用 `ROLLUP`
-* 需要**多维交叉分析**（如 地区×产品×时间）时使用 `CUBE`
-* 需要**自定义组合**时使用 `GROUPING SETS`
-
-***
-
-## 六、HAVING 子句：过滤聚合结果
-
-### 6.1 WHERE vs HAVING
-
-| 子句         | 执行时机 | 作用对象  | 可用函数            |
-| ---------- | ---- | ----- | --------------- |
-| **WHERE**  | 分组前  | 原始行数据 | 标量函数、列比较        |
-| **HAVING** | 分组后  | 聚合结果  | 聚合函数、GROUP BY 列 |
-
-**执行顺序**：FROM → WHERE → GROUP BY → HAVING → SELECT → ORDER BY → LIMIT
-
-***
-
-### 6.2 使用 HAVING 过滤聚合结果
-
-筛选总销量超过 15 辆的城市：
-
-```sql
-SELECT 
-    city,
-    COUNT(*) AS record_count,
-    SUM(quantity) AS total_quantity
-FROM dealer
-GROUP BY city
-HAVING SUM(quantity) > 15
-ORDER BY total_quantity DESC
-LIMIT 50;
-```
-
-**查询结果**：
-
-| city    | record\_count | total\_quantity |
-| ------- | ------------- | --------------- |
-| Dublin  | 3             | 33              |
-| Fremont | 3             | 32              |
-
-San Jose（总销量 13 辆）被过滤掉，因为不满足 `HAVING` 条件。
-
-***
-
-### 6.3 WHERE 与 HAVING 组合
-
-先用 `WHERE` 过滤原始数据，再用 `HAVING` 过滤聚合结果：
-
-```sql
-SELECT 
-    city,
-    COUNT(*) AS record_count,
-    SUM(quantity) AS total_quantity
-FROM dealer
-WHERE quantity >= 10  -- 先过滤：只统计销量≥10的记录
-GROUP BY city
-HAVING COUNT(*) >= 2  -- 再过滤：只显示记录数≥2的城市
-ORDER BY total_quantity DESC
-LIMIT 50;
-```
-
-**执行逻辑**：
-
-1. **WHERE 过滤**：排除 quantity < 10 的记录（过滤掉 4 条记录）
-2. **GROUP BY 分组**：对剩余记录按 city 分组
-3. **HAVING 过滤**：只保留记录数 ≥ 2 的分组
-
-***
-
-## 七、高级应用场景
-
-### 7.1 行转列：透视分析
-
-将车型从行转换为列，实现透视表效果：
-
-```sql
-SELECT 
-    city,
-    SUM(CASE WHEN car_model = 'Honda Civic' THEN quantity ELSE 0 END) AS civic_sales,
-    SUM(CASE WHEN car_model = 'Honda Accord' THEN quantity ELSE 0 END) AS accord_sales,
-    SUM(CASE WHEN car_model = 'Honda CRV' THEN quantity ELSE 0 END) AS crv_sales,
-    SUM(quantity) AS total_sales
-FROM dealer
-GROUP BY city
-ORDER BY total_sales DESC
-LIMIT 50;
-```
-
-**查询结果**：
-
-| city     | civic\_sales | accord\_sales | crv\_sales | total\_sales |
-| -------- | ------------ | ------------- | ---------- | ------------ |
-| Dublin   | 20           | 10            | 3          | 33           |
-| Fremont  | 10           | 15            | 7          | 32           |
-| San Jose | 5            | 8             | 0          | 13           |
-
-**业务价值**：
-
-* 清晰展示每个城市各车型的销量分布
-* San Jose 没有 CRV 销售记录（显示为 0）
-* 适合用于 Excel 报表、BI 仪表板
-
-***
-
-### 7.2 占比分析：窗口函数与 GROUP BY
-
-计算每个车型在其所在城市的销量占比：
-
-```sql
-SELECT 
-    city,
-    car_model,
-    quantity,
-    SUM(quantity) OVER (PARTITION BY city) AS city_total,
-    ROUND(quantity * 100.0 / SUM(quantity) OVER (PARTITION BY city), 2) AS percentage
-FROM dealer
-ORDER BY city, car_model
-LIMIT 50;
-```
-
-**查询结果**：
-
-| city     | car\_model   | quantity | city\_total | percentage |
-| -------- | ------------ | -------- | ----------- | ---------- |
-| Dublin   | Honda Accord | 10       | 33          | 30.30      |
-| Dublin   | Honda CRV    | 3        | 33          | 9.09       |
-| Dublin   | Honda Civic  | 20       | 33          | 60.61      |
-| Fremont  | Honda Accord | 15       | 32          | 46.88      |
-| Fremont  | Honda CRV    | 7        | 32          | 21.88      |
-| Fremont  | Honda Civic  | 10       | 32          | 31.25      |
-| San Jose | Honda Accord | 8        | 13          | 61.54      |
-| San Jose | Honda Civic  | 5        | 13          | 38.46      |
-
-**业务洞察**：
-
-* **Dublin**：Honda Civic 占比 60.61%，是绝对主力车型
-* **Fremont**：销量分布较均衡，Accord 占比最高（46.88%）
-* **San Jose**：Accord 占比 61.54%，市场偏好明显
-
-**技术说明**：窗口函数 `SUM() OVER (PARTITION BY city)` 计算每个城市的总销量，但不改变行数。
-
-***
-
-### 7.3 同比环比分析模式
-
-虽然示例数据不包含时间维度，但提供标准的同比/环比分析 SQL 模式：
-
-```sql
--- 示例：按月统计销量，计算环比增长
-SELECT 
-    DATE_FORMAT(sale_date, 'yyyy-MM') AS month,
-    SUM(quantity) AS monthly_sales,
-    LAG(SUM(quantity)) OVER (ORDER BY DATE_FORMAT(sale_date, 'yyyy-MM')) AS prev_month_sales,
-    ROUND(
-        (SUM(quantity) - LAG(SUM(quantity)) OVER (ORDER BY DATE_FORMAT(sale_date, 'yyyy-MM'))) * 100.0 / 
-        LAG(SUM(quantity)) OVER (ORDER BY DATE_FORMAT(sale_date, 'yyyy-MM')), 
-        2
-    ) AS mom_growth_rate
-FROM sales_table
-GROUP BY DATE_FORMAT(sale_date, 'yyyy-MM')
-ORDER BY month;
-```
-
-**关键技术**：
-
-* `LAG()` 窗口函数获取上一行的值
-* 环比增长率 = (当前值 - 上期值) / 上期值 × 100%
-
-***
-
-### 7.4 TopN 分析：每组取前 N
-
-使用窗口函数结合 GROUP BY 实现分组 TopN：
-
-```sql
--- 示例：每个城市销量前 2 的车型
-SELECT *
-FROM (
-    SELECT 
-        city,
-        car_model,
-        quantity,
-        ROW_NUMBER() OVER (PARTITION BY city ORDER BY quantity DESC) AS rank
-    FROM dealer
-) ranked
-WHERE rank <= 2
-ORDER BY city, rank;
-```
-
-**预期逻辑**（基于当前数据）：

-## 八、性能优化与最佳实践
-
-### 8.1 查询性能优化
-
-#### 1. 合理使用 LIMIT
-
-对于大数据集，始终添加 `LIMIT` 限制返回行数：
-
-```sql
--- 推荐
-SELECT city, SUM(quantity) 
-FROM large_table 
-GROUP BY city
-LIMIT 100;
-
--- 避免：可能返回数百万行
-SELECT city, SUM(quantity) 
-FROM large_table 
-GROUP BY city;
-```
-
-#### 2. 选择合适的聚合工具
-
-| 需求     | 推荐方案            | 生成分组数 | 性能    |
-| ------ | --------------- | ----- | ----- |
-| 简单层级汇总 | `ROLLUP`        | n+1   | ⭐⭐⭐⭐⭐ |
-| 多维交叉分析 | `CUBE`          | 2ⁿ    | ⭐⭐⭐   |
-| 自定义分组集 | `GROUPING SETS` | 自定义   | ⭐⭐⭐⭐  |
-
-**示例**：对于 3 列分组
-
-* `ROLLUP(a,b,c)` 生成 4 个分组集
-* `CUBE(a,b,c)` 生成 8 个分组集
-* `GROUPING SETS` 可自定义任意组合
-
-#### 3. 降低分组列基数
-
-对高基数列（如 ID、timestamp）使用函数降低粒度：
-
-```sql
--- 避免：按秒级 timestamp 分组
-GROUP BY timestamp  -- 可能产生数百万个分组
-
--- 推荐：按小时或天分组
-GROUP BY DATE_FORMAT(timestamp, 'yyyy-MM-dd')
-GROUP BY DATE_TRUNC('hour', timestamp)
-```
-
-#### 4. WHERE 过滤优于 HAVING 过滤
-
-尽量在 `WHERE` 中过滤数据，减少 `GROUP BY` 处理的数据量：
-
-```sql
--- 推荐：先过滤再分组
-SELECT city, SUM(quantity)
-FROM dealer
-WHERE car_model = 'Honda Civic'  -- 先过滤，减少数据量
-GROUP BY city;
-
--- 避免：先分组再过滤（处理了不必要的数据）
-SELECT city, car_model, SUM(quantity)
-FROM dealer
-GROUP BY city, car_model
-HAVING car_model = 'Honda Civic';
-```
-
-***
-
-### 8.2 常见错误与解决方案
-
-#### 错误 1：SELECT 列未在 GROUP BY 中
-
-```sql
--- ❌ 错误示例
-SELECT city, car_model, quantity
-FROM dealer
-GROUP BY city;
--- 错误：car_model 和 quantity 未分组或聚合
-
--- ✅ 正确方案1：添加到 GROUP BY
-SELECT city, car_model, SUM(quantity)
-FROM dealer
-GROUP BY city, car_model;
-
--- ✅ 正确方案2：使用聚合函数
-SELECT city, MAX(car_model), SUM(quantity)
-FROM dealer
-GROUP BY city;
-```
-
-#### 错误 2：WHERE 中使用聚合函数
-
-```sql
--- ❌ 错误示例
-SELECT city, SUM(quantity)
-FROM dealer
-WHERE SUM(quantity) > 20  -- WHERE 不能使用聚合函数
-GROUP BY city;
-
--- ✅ 正确方案：使用 HAVING
-SELECT city, SUM(quantity)
-FROM dealer
-GROUP BY city
-HAVING SUM(quantity) > 20;
-```
-
-#### 错误 3：混淆 ROLLUP/CUBE 语法
-
-```sql
--- ❌ 错误示例
-GROUP BY city, ROLLUP(car_model)  -- 不支持混合语法
-
--- ✅ 正确方案
-GROUP BY ROLLUP(city, car_model)
-```
-
-#### 错误 4：忽略 NULL 值影响
-
-```sql
--- 在 ROLLUP/CUBE 中，NULL 既可能是真实 NULL，也可能是汇总标记
--- 使用 GROUPING() 函数区分
-
-SELECT 
-    CASE WHEN GROUPING(city) = 1 THEN 'Total' ELSE city END AS city,
-    SUM(quantity)
-FROM dealer
-GROUP BY ROLLUP(city);
-```
-
-***
-
-### 8.3 数据质量检查
-
-#### 检查分组完整性
-
-验证分组汇总是否等于总计：
-
-```sql
--- 方法1：使用 ROLLUP 自动生成总计行
-SELECT 
-    COALESCE(city, 'TOTAL') AS city,
-    SUM(quantity) AS total
-FROM dealer
-GROUP BY ROLLUP(city);
-
--- 方法2：手动验证
-WITH group_totals AS (
-    SELECT SUM(quantity) AS grouped_sum
-    FROM dealer
-    GROUP BY city
-),
-grand_total AS (
-    SELECT SUM(quantity) AS total_sum
-    FROM dealer
-)
-SELECT 
-    (SELECT SUM(grouped_sum) FROM group_totals) AS sum_of_groups,
-    (SELECT total_sum FROM grand_total) AS grand_total,
-    CASE 
-        WHEN (SELECT SUM(grouped_sum) FROM group_totals) = (SELECT total_sum FROM grand_total)
-        THEN 'PASS'
-        ELSE 'FAIL'
-    END AS validation_result;
-```

-| **适用场景**  | 基础统计     | 自定义多维分析       | 层级报表   | 全维交叉分析   |
-
-***
-
-### 10.2 选择决策树
-
-```
-是否需要多维度汇总？
-├─ 否 → 使用标准 GROUP BY
-└─ 是 → 需要哪些维度组合？
-    ├─ 所有可能组合 → 使用 CUBE
-    ├─ 层级汇总（从细到总）→ 使用 ROLLUP
-    └─ 自定义特定组合 → 使用 GROUPING SETS
-```
-
-***
-
-### 10.3 推荐使用场景
-
-| 业务场景     | 推荐方案                 | 示例           |
-| -------- | -------------------- | ------------ |
-| 日常统计报表   | `GROUP BY`           | 按部门统计销售额     |
-| 财务分层汇总   | `ROLLUP`             | 公司→部门→团队层级汇总 |
-| BI 数据透视表 | `CUBE`               | 产品×地区×时间三维分析 |
-| 自定义业务报表  | `GROUPING SETS`      | 同时输出日报、周报、月报 |
-| 占比分析     | `GROUP BY` + 窗口函数    | 各产品销量占比      |
-| Top N 分析 | `GROUP BY` + `LIMIT` | 销量前10的产品     |
-
-***
-
-## 十一、进阶技巧
-
-### 11.1 动态分组
-
-使用变量或子查询实现动态分组条件（示例逻辑）：
-
-```sql
--- 根据销量范围动态分组
-SELECT 
-    CASE 
-        WHEN SUM(quantity) >= 30 THEN 'High Volume'
-        WHEN SUM(quantity) >= 15 THEN 'Medium Volume'
-        ELSE 'Low Volume'
-    END AS volume_tier,
-    COUNT(DISTINCT city) AS city_count
-FROM (
-    SELECT city, SUM(quantity) AS city_total
-    FROM dealer
-    GROUP BY city
-) city_summary
-GROUP BY 
-    CASE 
-        WHEN city_total >= 30 THEN 'High Volume'
-        WHEN city_total >= 15 THEN 'Medium Volume'
-        ELSE 'Low Volume'
-    END;
-```
-
-***
-
-### 11.2 递归汇总（模拟）
-
-虽然云器 Lakehouse 目前还不直接支持递归 CTE，但可通过 UNION ALL 模拟多层级汇总：
-
-```sql
--- 三层汇总：明细、城市小计、总计
-SELECT city, car_model, quantity, 'Detail' AS level
-FROM dealer
-UNION ALL
-SELECT city, NULL, SUM(quantity), 'City Subtotal'
-FROM dealer
-GROUP BY city
-UNION ALL
-SELECT NULL, NULL, SUM(quantity), 'Grand Total'
-FROM dealer
-ORDER BY 
-    CASE level 
-        WHEN 'Detail' THEN 1
-        WHEN 'City Subtotal' THEN 2
-        WHEN 'Grand Total' THEN 3
-    END,
-    city,
-    car_model;
-```
-
-***
-
-### 11.3 NULL 值处理技巧
-
-#### 技巧 1：区分真实 NULL 和聚合 NULL
-
-```sql
-SELECT 
-    city,
-    car_model,
-    SUM(quantity) AS total,
-    CASE 
-        WHEN GROUPING(city) = 1 THEN '[Subtotal]'
-        WHEN city IS NULL THEN '[Real NULL]'
-        ELSE city
-    END AS city_display
-FROM dealer
-GROUP BY ROLLUP(city, car_model);
-```
-
-#### 技巧 2：使用 COALESCE 美化输出
-
-```sql
-SELECT 
-    COALESCE(city, '📊 All Cities') AS city,
-    COALESCE(car_model, '🚗 All Models') AS car_model,
-    SUM(quantity) AS total
-FROM dealer
-GROUP BY CUBE(city, car_model);
-```
-
-***
-

-## IFNULL 函数
-
-IFNULL 函数是一个逻辑函数，用于处理 SQL 查询中可能出现的 NULL 值。当第一个参数的值为 NULL 时，IFNULL 函数返回第二个参数的值；如果第一个参数的值不为 NULL，则返回第一个参数的值。
-
-### 语法
-
-```sql
-IFNULL(expression_1, expression_2)
-```
-
-- `expression_1`：需要检查的表达式，通常是一个字段名。
-- `expression_2`：当 `expression_1` 为 NULL 时，要返回的值。
-
-### 使用说明
-
-- `expression_1` 和 `expression_2` 的数据类型必须相同或兼容。
-- 如果 `expression_1` 和 `expression_2` 的数据类型不兼容，IFNULL 函数将返回 NULL。
-- IFNULL 函数的返回值是 `expression_1` 或 `expression_2` 的数据类型。
-
-### 示例
-
-假设有一个名为 `student` 的表，包含以下列：
-
-- `id`：学生的唯一标识。
-- `name`：学生的姓名。
-- `score`：学生的成绩。
-
-表 `student` 的数据如下：
-
-| id | name  | score |
-|----|-------|-------|
-| 1  | Alice | 90    |
-| 2  | Bob   | NULL  |
-| 3  | Cathy | 80    |
-| 4  | David | NULL  |
-
-现在，我们想要查询每个学生的姓名和成绩，将成绩为 NULL 的记录替换为 0。可以使用以下 SQL 语句：
-
-```sql
-SELECT name, IFNULL(score, 0) AS score FROM student;
-```
-
-查询结果如下：
-
-| name  | score |
-|-------|-------|
-| Alice | 90    |
-| Bob   | 0     |
-| Cathy | 80    |
-| David | 0     |
-
-### 更多示例
-
-1. 查询学生的姓名和年龄，如果年龄为 NULL，则显示为 "Unknown"：
-
-```sql
-SELECT name, IFNULL(age, 'Unknown') AS age FROM student;
-```
-
-2. 查询员工的姓名和工资，如果工资为 NULL，则显示为 "Not available"：
-
-```sql
-SELECT name, IFNULL(salary, 'Not available') AS salary FROM employee;
-```
-
-3. 查询产品的名称和库存数量，如果库存数量为 NULL，则显示为 "Out of stock"：
-
-```sql
-SELECT product_name, IFNULL(stock_quantity, 'Out of stock') AS stock FROM products;
-```
-
-通过使用 IFNULL 函数，我们可以确保查询结果中不会出现 NULL 值，从而提高数据的可读性和可用性。

-# ilike运算符使用指南
-
-ilike运算符是SQL语句中用于判断字符串匹配模式的一种工具，它能够忽略大小写的差异，从而更加灵活方便地进行字符串匹配。与传统的like运算符相比，ilike运算符在处理大小写不一致的情况时更为方便。
-
-## 语法
-
-ilike运算符的基本语法如下：
-
-```SQL
-str [ NOT ] ilike pattern [ escape escape_char ]
-str [ NOT ] ilike { ANY | SOME | ALL } ( [ pattern [, ...] ] ) [ escape escape_char ]
-```
-
-在这里，`str`代表要匹配的字符串表达式，`pattern`代表要匹配的模式表达式，`escape escape_char`是用于转义特殊字符的单字符字符串字面量。`ANY`、`SOME`和`ALL`用于指定多个模式之间的逻辑关系。当使用`ALL`时，表示`str`必须匹配所有模式；而使用`ANY`或`SOME`时，表示`str`只需匹配至少一个模式。
-
-### ilike的模式
-
-ilike的模式中可以包含以下特殊字符：
-
-- `_`：匹配任意单个字符（类似于POSIX正则表达式中的`.`）。
-- `%`：匹配任意个数的字符（类似于POSIX正则表达式中的`.*`）。
-
-## 使用示例
-
-假设有一个名为students的表，它包含学生的姓名和班级信息，如下所示：
-
-```SQL
-CREATE TABLE students (
-  name STRING,
-  class STRING
-);
-
-INSERT INTO students (name, class) VALUES
-('Alice', 'A'),
-('Bob', 'B'),
-('Carol', 'A'),
-('David', 'C');
-```
-
-以下是使用ilike运算符的查询示例：
-
-1.  查询姓名中包含“a”（不区分大小写）的学生：
-
-```SQL
-SELECT name, class
-FROM students
-WHERE name ILIKE '%a%';
-
-+-------+-------+
-| name  | class |
-+-------+-------+
-| Alice | A     |
-| Carol | A     |
-| David | C     |
-+-------+-------+
-```
-
-2.  查询姓名以“a”或“b”开头的学生（不区分大小写）：
-
-```SQL
-SELECT name, class
-FROM students
-WHERE name ILIKE ANY ('a%', 'b%');
-
-+-------+-------+
-| name  | class |
-+-------+-------+
-| Alice | A     |
-| Bob   | B     |
-+-------+-------+
-```
-
-3.  查询姓名中同时包含“a”和“l”的学生（不区分大小写）：
-
-```SQL
-SELECT name, class
-FROM students
-WHERE name ILIKE ALL ('%a%', '%l%');
-
-+-------+-------+
-| name  | class |
-+-------+-------+
-| Alice | A     |
-| Carol | A     |
-+-------+-------+
-```
-
-## 注意事项
-- 当使用ilike运算符时，如果模式中包含特殊字符，建议使用`escape`子句来转义这些特殊字符，以避免歧义。

-# 数据导入Lakehouse操作实践\_通过Python脚本
-
-在现代数据处理中，将数据导入数据库是一个常见的需求。使用 Python 脚本实现数据导入可以带来许多优势，适用于多种场景，例如自动化、数据处理、支持多种数据库等。本文将以 PostgreSQL 数据库为例，演示如何将数据导入云器 Lakehouse。
-
-## 优势介绍
-
-1. **自动化**：通过创建定期或按需运行的自动化任务，可以实现数据的实时更新或迁移。
-
-2. **数据处理**：Python 具有强大的数据处理功能，可以在将数据导入数据库之前对其进行预处理、清洗和转换，以提高数据质量与导入成功率。
-
-3. **支持多种数据库**：Python 提供了广泛的数据库驱动程序和库，支持关系型数据库（如 MySQL、PostgreSQL、SQLite 等）和非关系型数据库（如 MongoDB、Redis 等）。
-
-4. **错误处理和日志记录**：使用 Python 编写导入脚本时，可以捕获异常并记录详细日志，从而更容易地跟踪和解决数据导入过程中的问题。
-
-## 适用场景举例
-
-1. 将 CSV 或 Excel 文件中的数据导入数据库。
-2. 在将数据导入数据库之前，对数据应用统计方法或规范化等方法进行预处理。
-3. 包含数据验证和完整性检查的数据库迁移任务。
-
-## 操作指南
-
-### 1. 导入需要的Python包
-
-```python
-from sqlalchemy import create_engine
-import pandas as pd
-import psycopg2
-import pygwalker as pyg
-```
-
-### 2. 创建连接到 PostgreSQL 数据库并读取源表数据
-
-```python
-def create_conn_pg(database: str, user: str, password: str, host: str, port: str):
-    connection = psycopg2.connect(
-        dbname=database,
-        user=user,
-        password=password,
-        host=host,
-        port=port
-    )
-    return connection
-```
-
-### 3. 使用 `pd.read_sql_query()` 方法从数据库中查询数据并存储到 DataFrame 中
-
-```python
-conn_pg = create_conn_pg("<database>", "<username>", "<password>", "<host>", "<port>")
-query = "SELECT * FROM public.orders;"
-df = pd.read_sql_query(query, conn_pg)
-conn_pg.close()
-```
-
-### 4. 查看 PostgreSQL 数据并进行清洗与可视化分析
-
-```python
-# 查看数据总行数
-print(df.shape[0])
-
-# 替换所有nan值为0
-df.fillna(0, inplace=True)
-
-# 显示前5行数据
-print(df.head(5))
-```
-
-### 5. 使用 PyGWalker 进行数据透视分析（可选）
-
-```python
-walker = pyg.walk(df)
-```
-
-### 6. 在 ClickZetta Lakehouse 中创建目标表
-
-```python
-engine_cz = create_engine("clickzetta://<username>:<password>@<instanceid>.<region_id>.api.clickzetta.com/<workspacename>?virtualcluster=<vcluster>&schema=<public>")
-sql_cz = text("""
-CREATE TABLE IF NOT EXISTS orders_tmp (
-    id INT,
-    user_id INT,
-    product_id INT,
-    subtotal DECIMAL(8, 2),
-    tax DECIMAL(8, 2),
-    total DECIMAL(16, 3),
-    discount DECIMAL(8, 2),
-    created_at TIMESTAMP,
-    quantity INT
-);
-""")
-with engine_cz.connect() as conn:
-    results = conn.execute(sql_cz)
-```
-
-### 7. 将转换后的源表数据写入云器 Lakehouse 目标表
-
-```python
-conn_cz = connect(
-    username="<username>",
-    password="<password>",
-    service="<region_id>.api.clickzetta.com",
-    instance="<instanceid>",
-    workspace="<workspacename>",
-    schema="public",
-    vcluster="default"
-)
-bulkload_stream = conn_cz.create_bulkload_stream(schema="public", table="orders")
-writer = bulkload_stream.open_writer(0)
-for index, row_data in df.iterrows():
-    row = writer.create_row()
-    row.set_value("id", row_data["id"])
-    row.set_value("created_at", row_data["created_at"])
-    row.set_value("user_id", row_data["user_id"])
-    row.set_value("product_id", row_data["product_id"])
-    row.set_value("subtotal", row_data["subtotal"])
-    row.set_value("tax", row_data["tax"])
-    row.set_value("total", row_data["total"])
-    row.set_value("discount", row_data["discount"])
-    row.set_value("quantity", row_data["quantity"])
-    writer.write(row)
-writer.close()
-bulkload_stream.commit()
-```
-
-### 8. 资源清理
-
-```
-#删除云器 Lakehouse目标表
-sql_cz = text("""drop table if exists orders ;""")
-with engine_cz.connect() as conn:
-    results = conn.execute(sql_cz)

-# 介绍
-
-LAKEHOUSE 的 INFORMATION_SCHEMA 提供了项目实例（INSTANCE）及使用历史数据等详细信息，帮助您全面了解所有空间的信息。通过查询INFORMATION_SCHEMA，您可以查看所有空间的元数据信息和使用历史信息。INFORMATION_SCHEMA 基于 ANSI SQL-92 标准，同时增加了一些 LAKEHOUSE 服务特有的字段和视图。当您创建 LAKEHOUSE 实例时，系统会自动在名为 SYS 的系统空间中创建一个 INFORMATION_SCHEMA。INFORMATION_SCHEMA不仅记录了当前存在的元数据对象，还记录了已经删除的元数据对象。您可以通过DELETE_TIME字段来判断一个元数据对象是否被删除，以及删除的时间。如果DELETE_TIME字段为NULL，表示该元数据对象尚未被删除。需要注意的是，目前存在约 15 分钟的延迟。
-
-# 使用限制
-
-* 实例级别 SYS 下的视图，被删除对象保留 60 天记录。视图当前阶段存在约 15 分钟的延迟。JOB_HISTORY、MATERIALIZED_VIEW 刷新视图保留 60 天记录。
-* 每个INFORMATION_SCHEMA下的表和视图都是只读的（不能修改或删除）。
-* 对 INFORMATION_SCHEMA 视图的查询不保证与并发 DDL 操作的一致性。例如，在执行长时间运行的 INFORMATION_SCHEMA 查询时创建了一组表，则查询结果可能不包含这些新创建的表。
-
-# 访问SYS下的INFORMATION_SCHEMA
-
-要访问 SYS 下的 INFORMATION_SCHEMA，您需要具备 INSTANCE ADMIN 权限。以下是查询 INFORMATION_SCHEMA 的一个示例：
-
-```SQL
-SELECT * FROM SYS.information_schema.tables;
-```
-
-以下是一些查询INFORMATION_SCHEMA的示例，帮助您更好地了解如何使用这些视图和表。
-
-1. 查询所有空间的元数据信息：
-
-```SQL
-SELECT * FROM SYS.information_schema.columns;
-```
-
-2. 查询指定空间的表信息：
-
-```SQL
-SELECT * FROM SYS.information_schema.tables WHERE table_schema = 'your_schema_name';
-```
-
-3. 查询已删除的元数据对象：
-
-```SQL
-SELECT * FROM SYS.information_schema.columns WHERE delete_time IS NOT NULL;
-```
-
-4. 查询表的创建时间：
-
-```SQL
-SELECT table_name, create_time FROM SYS.information_schema.tables WHERE table_schema = 'your_schema_name';
-```
-
-5. 查询JOB HISTORY信息：
-
-```SQL
-SELECT * FROM SYS.information_schema.job_history;
-```
-
-通过以上示例，您可以更深入地了解如何使用 INFORMATION_SCHEMA 来查询和管理 LAKEHOUSE 实例中的元数据和使用历史信息。

-# 使用内部 Volume
-
-内部 Volume（Internal Volume）是系统提供的默认文件存储区域，用于临时存放待处理或待加载的数据文件。
-
-* 对于没有云存储的用户，可以直接上传文件到内部 Volume 作为数据文件的主要存储区域，系统提供完全托管的存储服务。
-* 而已使用云对象存储的用户，则可以选择使用外部 Volume（External Volume），通过直接挂载云存储路径进行访问，无需额外的数据迁移和复制。
-
-系统目前支持三种类型的内部 Volume：User Volume、Table Volume 和命名 Volume。
-
-### 使用User Volume
-
-User Volume 是用户专属的个人存储空间，类似于操作系统中用户的默认工作目录，在 Lakehouse 中这个目录不可删除。用户默认对 User Volume 具备读写权限。
-
-| **用户对 USER VOLUME 的操作** |
-| :------------------------- |
-| SHOW USER VOLUME DIRECTORY |
-| SELECT FROM VOLUME         |
-| PUT                        |
-| GET                        |
-| LIST USER VOLUME           |
-| REMOVE                     |
-
-* 查看User Volume下文件
-
-```SQL
---查看user volume
-SHOW USER VOLUME DIRECTORY;

-
-* 上传、下载与删除文件
-
-```SQL
---上传文件至user volume根目录
-PUT '/Users/Downloads/taxi_zone_lookup.csv' TO USER VOLUME;
-
---上传文件并保存为user volume指定目录下指定文件名称
-PUT '/Users/Downloads/taxi_zone_lookup.csv' TO USER VOLUME FILE 'tmp/taxi_zone_lookup_02.csv';
-
---通过通配符上传多个文件到Volume子目录
-PUT '/Users/Downloads/images/*' TO USER VOLUME SUBDIRECTORY 'images/';
-
---从User Volume下载文件
-GET USER VOLUME FILE 'images/image-2024-05-22-11-25-23-519.png' TO '/Users/Downloads/output/' ;

-
-
---通过SQL查询User Volume指定路径下所有文件
-SELECT * FROM USER VOLUME using csv subdirectory '/tmp/';
-```
-
-* 使用 `get_presigned_url` 函数，获取 Volume 下文件在对象存储的待临时签名的真实访问路径。
-
-```SQL
---获取presign url, 获取oss内网url
-SELECT get_presigned_url(USER VOLUME , 'images/image.png' , 60) as url;
-
---获取presign url,获取对外url
-set cz.sql.function.get.presigned.url.force.external=true;
-SELECT get_presigned_url(USER VOLUME , 'images/image.png' , 60) as url;
-```
-
-### 使用Table Volume
-
-每个Lakehouse 表默认关联一个存储空间，我们称之为Table Volume。用户对指定表的 Table Volume 进行操作时需要具备以下权限：
-
-| **TABLE VOLUME 操作**                         | **对应 TABLE 权限需求**        |
-| :----------------------------------------- | :--------------------- |
-| SHOW TABLE VOLUME DIRECTORY \<table\_name> | SELECT                 |
-| SELECT FROM VOLUME \<table\_name>          | SELECT                 |
-| PUT                                        | INSERT,UPDATE,DELETE   |
-| GET                                        | SELECT                 |
-| LIST                                       | SCHEMA READ            |
-| REMOVE                                     | INSERT, UPDATE, DELETE |
-
-以下通过示例说明 Table Volume 的操作使用。
-
-```SQL
---创建表
-CREATE TABLE t_copy_from_volume(id int, name string);
-
---查看指定表的Table volume
-SHOW TABLE VOLUME DIRECTORY t_copy_from_volume;
-```
-
-上传文件至目标表的TABLE VOLUME，要求访问用户具有目标表的写入权限。
-
-```SQL
---上传文件至table volume，不指定存储路径默认保存在根路径下
-PUT '/Users/Downloads/data.csv' TO TABLE VOLUME t_copy_from_volume FILE 'data.csv';
-
-source                           target   source_size target_size status  
--------------------------------- -------- ----------- ----------- ------- 
-/Users/Downloads/data.csv data.csv 34          34          SUCCEED 
-```
-
-使用SQL探查上传至TABLE VOLUME下文件数据。
-
-```SQL
---查询
-SELECT * FROM TABLE VOLUME t_copy_from_volume
-USING CSV
-OPTIONS(
-        'header'='true',
-        'lineSep'='\n'
-)
-
-id name  
--- ----- 
-1  hello 
-2  world 
-3  !     
-```
-
-使用COPY INTO命令导入文件数据到目标表。
-
-```SQL
-COPY INTO t_copy_from_volume FROM TABLE VOLUME t_copy_from_volume(id int, name string)  USING csv  
-OPTIONS(
-        'header'='true',
-        'lineSep'='\n'
-)
-FILES ('data.csv')
---删除volume中的文件，节省存储
-PURGE=TRUE;
-```
-
-查询目标表，验证导入结果。
-
-```SQL
---查看导入结果
-SELECT * FROM t_copy_from_volume;
-
-id name  
--- ----- 
-1  hello 
-2  world 
-3  !     
-```
-
-删除TABLE VOLUME下文件。
-
-```SQL
---删除Table Volume下指定文件
-REMOVE TABLE VOLUME t_copy_from_volume  FILE 'data.csv'
---删除Table Volume下指定路径下所有文件
-REMOVE TABLE VOLUME t_copy_from_volume subdirectory '/'
-```
-
-### 使用命名Volume
-
-命名 Volume 是用户显式创建的，创建后存储在 Lakehouse 管理的内部存储中，无需额外云存储配置。它提供了比自动生成的用户级（User Volume）和表级（Table Volume）更精细的控制能力。
-
-#### 语法说明
-
-##### 创建命名 Volume
-
-```SQL
-CREATE VOLUME [ IF NOT EXISTS ] <volume_name>
-    DIRECTORY = (
-        enable =  true,    
-        auto_refresh = true
-    )
-    RECURSIVE = true          -- 是否递归扫描子目录（默认false）
-```
-
-^
-
-#### 删除Volume
-
-```SQL
-DROP VOLUME [ IF EXISTS ] <volume_name>
-```
-
-#### 使用具体案例
-
-上传和下载数据
-
-```sql
---创建volume
-CREATE  VOLUME my_volume
-    DIRECTORY = (
-        enable=true,
-        auto_refresh=true
-    )
-    RECURSIVE=true;
-SHOW VOLUME DIRECTORY my_volume;
-
-COPY INTO VOLUME my_volume  SUBDIRECTORY 'dau_unload/'
-FROM TABLE public.students01
-file_format = (
-    type= CSV
-    writebom=true
-);
-SHOW VOLUME DIRECTORY my_volume;
---本地上传下载测试
-GET VOLUME my_volume FILE 'dau_unload/part00001.csv' TO '/tmp';
-+---------------+--------------------+-------------+-------------+---------+
-|    source     |       target       | source_size | target_size | status  |
-+---------------+--------------------+-------------+-------------+---------+
-| part00001.csv | /tmp/part00001.csv | 1472        | 1472        | SUCCEED |
-+---------------+--------------------+-------------+-------------+---------+
-
- PUT '/tmp/part00001.csv' to volume my_volume file 'my.csv';
-+--------------------+--------+-------------+-------------+---------+
-|       source       | target | source_size | target_size | status  |
-+--------------------+--------+-------------+-------------+---------+
-| /tmp/part00001.csv | my.csv | 1472        | 1472        | SUCCEED |
-+--------------------+--------+-------------+-------------+---------+
-

-# 倒排索引
-
-## 概述
-
-### 倒排索引原理介绍
-
-1. 基本概念
-   倒排索引由两部分组成：
-   * **词典（Dictionary）**：存储所有文档集合中出现过的唯一单词（或短语）的列表。
-   * **倒排表（Posting List）**：对于词典中的每个单词，都有一个与之对应的倒排列表，记录了包含这个单词的所有文档的文档ID以及单词在文档中出现的位置信息。
-
-2. 构建过程
-   * **分词（Tokenization）**：将文档内容分割成单词或短语的过程。
-   * **标准化（Normalization）**：对分词结果进行处理，如转小写、去除停用词、词干提取等。
-   * **构建词典**：将处理后的单词加入词典，并为每个单词分配一个唯一的ID。
-   * **构建倒排列表**：对于每个文档，记录下文档中所有单词的ID和位置信息，并将这些信息与词典中的单词ID关联起来，形成倒排列表。
-
-3. 查询过程
-   当用户提交一个查询请求时，搜索引擎会执行以下步骤：
-   * **查询解析**：将用户的查询语句分解成单词或短语。
-   * **查找词典**：在词典中查找这些单词或短语的ID。
-   * **检索倒排列表**：根据单词ID，从倒排列表中检索包含这些单词的所有文档ID。
-   * **合并结果**：根据查询语句中的逻辑（如AND、OR、NOT等），合并不同单词的检索结果，确定最终的文档列表。
-
-4. 应用场景
-   倒排索引主要用于全文搜索领域，如搜索引擎、文档检索系统等，它能够快速响应用户的查询请求，提供高效的检索服务。
-
-### 功能介绍
-
-利用倒排索引可以根据关键词快速定位包含它的行，达到查询加速的目的。同时，如上文原理介绍，词典和倒排列表会产生额外的 Lakehouse 存储。
-
-1. 全文检索能力
-   支持字符串类型的全文检索，支持`match_all`、`match_any`、`match_phrase`、`match_phrase_prefix`、`match_regexp`函数。Lakehouse 在部分场景下`like`也会使用倒排索引，但仍推荐您使用全文检索函数。
-
-2. 查询加速
-   * 支持字符串、数值类型的 =、!=、>、>=、<, <=
-BUILD INDEX index_name ON table_name WHERE partition_name1 = '1' and partition_name2 = '2';
-```
-
-* index\_name：指定要添加倒排索引名称
-* 支持指定分区构建：可以指定一个或者多个
-
-#### 说明
-
-执行BUILD INDEX是一个同步任务，执行过程会消耗计算资源。查看进度可以通过Job Profile查看。
-
-当分区表数据量较大时，建议以分区为粒度依次创建索引。
-
-#### 案例

-### 删除倒排索引
-
-#### 语法
-
-```SQL
-DROP INDEX [IF EXISTS] index_name;
-```
-
-参数说明：
-
-* `DROP INDEX`：删除索引的关键字。
-* `IF EXISTS`：可选参数，如果指定的索引不存在，则不报错。
-* `index_name`：要删除的索引名称。
-
-#### 说明
-
-执行drop index会立即成功，会删除掉index的元数据信息。但是不会立即删除索引存储信息。
-
-## 分析器高级配置
-
-在创建倒排索引时，除了指定分析器类型（`analyzer`），还可以通过 `PROPERTIES` 配置停用词（stopwords）和词干提取（stemmer），进一步控制分词行为。
-
-### 停用词（Stopwords）
-
-停用词是指在全文检索中通常不携带实质意义、需要过滤掉的常见词汇（如英文中的 "the"、"is"、"a" 等）。过滤停用词可以减小索引体积、提升检索精度。
-
-支持两种配置方式：
-
-| 属性 | 说明 |
-|------|------|
-| `stopwords` | 使用内置停用词表，目前支持 `english` |
-| `custom_stopwords` | 自定义停用词，多个词用英文逗号分隔，优先级高于 `stopwords` |
-
-**默认行为**：不配置时停用词过滤默认关闭，所有词均会被索引。
-
-**示例：使用内置英文停用词**
-
-```SQL
-CREATE TABLE articles(
-   id INT,
-   content STRING,
-   INDEX content_index (content) INVERTED PROPERTIES('analyzer'='english', 'stopwords'='english')
-);
-```
-
-分词效果：`"The quick brown fox"` → `["quick", "brown", "fox"]`（"the" 被过滤）
-
-**示例：使用自定义停用词**
-
-```SQL
-CREATE TABLE articles(
-   id INT,
-   content STRING,
-   INDEX content_index (content) INVERTED PROPERTIES('analyzer'='english', 'custom_stopwords'='hello,world,test')
-);
-```
-
-分词效果：`"hello world this is a test"` → `["this", "is", "a"]`
-
-> **注意**：`custom_stopwords` 与 `stopwords` 同时配置时，`custom_stopwords` 优先生效，内置停用词表不会被使用。
-
-**内置英文停用词列表**
-
-内置英文停用词基于 Lucene/Elasticsearch 标准停用词表，包含：`a`、`an`、`and`、`are`、`as`、`at`、`be`、`but`、`by`、`for`、`if`、`in`、`into`、`is`、`it`、`no`、`not`、`of`、`on`、`or`、`such`、`that`、`the`、`their`、`then`、`there`、`these`、`they`、`this`、`to`、`was`、`will`、`with`。
-
-### 词干提取（Stemmer）
-
-词干提取将单词还原为词根形式，使不同形态的同一词汇能够匹配（如 `running`、`runs`、`ran` 均还原为 `run`）。底层使用 [Snowball](https://snowballstem.org/) 算法库。
-
-配置方式：
-
-| 属性 | 说明 |
-|------|------|
-| `stemmer` | 指定 Snowball 算法，格式为 `snowball_<language>`，如 `snowball_english`、`snowball_german`、`snowball_french` 等 |
-
-**示例：英文词干提取**
-
-```SQL
-CREATE TABLE articles(
-   id INT,
-   content STRING,
-   INDEX content_index (content) INVERTED PROPERTIES('analyzer'='english', 'stemmer'='snowball_english')
-);
-```
-
-分词效果：`"running quickly"` → `["run", "quick"]`
-
-**示例：词干提取 + 停用词组合使用**
-
-```SQL
-CREATE TABLE articles(
-   id INT,
-   content STRING,
-   INDEX content_index (content) INVERTED PROPERTIES(
-     'analyzer'='english',
-     'stemmer'='snowball_english',
-     'stopwords'='english'
-   )
-);
-```
-
-分词效果：`"The dogs are running"` → `["dog", "run"]`（"the"、"are" 被停用词过滤，"dogs" 和 "running" 经词干提取还原）
-
-> **注意**：词干提取在停用词过滤之前执行，处理顺序为：分词器 → 词干提取 → 停用词过滤。
-
-**在查询函数中使用**
-
-查询时同样可以通过 `option` 参数指定停用词和词干提取，确保查询分词与索引分词一致：
-
-```SQL
--- 使用停用词
-SELECT tokenize('The quick brown fox', map('analyzer', 'english', 'stopwords', 'english'));
--- 返回: ["quick", "brown", "fox"]
-
--- 使用词干提取
-SELECT tokenize('running quickly', map('analyzer', 'english', 'stemmer', 'snowball_english'));
--- 返回: ["run", "quick"]
-
--- 组合使用
-SELECT match_all(content, 'dogs running', map('analyzer', 'english', 'stemmer', 'snowball_english', 'stopwords', 'english'))
-FROM articles;
-```
-
-## 使用倒排索引查询
-
-### 倒排索引函数
-
-函数中要求分词和表保持一致，否则无法使用倒排索引加速查询。不指定option参数时会自动映射字段已有索引中的分词。
-
-#### tokenize
-
-**语法：**
-
-```SQL
-tokenize(input[, option])
-```
-
-**功能：** 分词，返回值为array
-
-**示例：**
-
-```SQL
-SELECT tokenize('a b', map('analyzer', 'english'));
--- 返回: ["a", "b"]
-```
-
-#### match_all
-
-**语法：**
-
-```SQL
-match_all(input, query[, option])
-```
-
-**功能：** 匹配所有，先将query分词，再将input分词，需要保证input的分词结果包含所有query分词结果，返回bool
-
-**示例：**
-
-```SQL
-SELECT match_all('a b c', 'b a', map('analyzer', 'english'));
--- 返回: true
-```
-
-#### match_any
-
-**语法：**
-
-```SQL
-match_any(input, query[, option])
-```
-
-**功能：** 匹配任意，input的分词结果包含query分词结果的任意元素即可，返回bool
-
-**示例：**
-
-```SQL
-SELECT match_any('a b c', 'd a', map('analyzer', 'english'));
--- 返回: true
-```
-
-#### match_phrase
-
-**语法：**
-
-```SQL
-match_phrase(input, query[, option])
-```
-
-**功能：** 匹配短语，在match_all的基础上，匹配的结果顺序要和query分词结果的顺序要一致且连续
-
-**示例：**
-
-```SQL
-SELECT match_phrase('a b c', 'a b', map('analyzer', 'english'));
--- 返回: true
-
-SELECT match_phrase('a b c', 'a c', map('analyzer', 'english'));
--- 返回: false (因为'a'和'c'在原文中不连续)
-```
-
-#### match_phrase_prefix
-
-**语法：**
-
-```SQL
-match_phrase_prefix(input, query[, option])
-```
-
-**功能：** 匹配短语前缀，input的分词结果，前n-1个匹配规则和match_phrase相同，最后一个元素符合前缀匹配
-
-**示例：**
-
-```SQL
-SELECT match_phrase_prefix('a b cd', 'b c', map('analyzer', 'english'));
--- 返回: true
-```
-
-#### match_regexp
-
-**语法：**
-
-```SQL
-match_regexp(input, query[, option])
-```
-
-**功能：** 匹配正则表达式，将input的分词结果，使用query的正则表达式匹配，有任意匹配即可
-
-**示例：**
-
-```SQL
-SELECT match_regexp('a b cd', 'c.*', map('analyzer', 'english'));
--- 返回: true
-```
-
-### 查询示例
-
-创建倒排索引的表
-
-```SQL
-CREATE TABLE bulkload_data(
-   id INT,
-   data STRING,
-   INDEX id_index (id) INVERTED,
-   INDEX data_index (data) INVERTED PROPERTIES('analyzer'='unicode')
-);
-```
-
-**插入测试数据：**
-
-```SQL
-INSERT INTO bulkload_data VALUES
-(1, 'Lakehouse provides distributed storage'),
-(2, 'Inverted index accelerates full text search'),
-(3, 'Lakehouse supports multiple data types'),
-(4, 'Full text search with inverted index'),
-(5, 'Data analytics on Lakehouse platform');
-```
-
-**全文检索示例：**
-
-```SQL
---匹配所有，包含Lakehouse和storage
-SELECT id, data FROM bulkload_data WHERE match_all(data, 'Lakehouse storage');
-+----+---------------------------------------+
-| id |                 data                  |
-+----+---------------------------------------+
-| 1  | Lakehouse provides distributed storage |
-+----+---------------------------------------+
-
---匹配任意，包含search或analytics
-SELECT id, data FROM bulkload_data WHERE match_any(data, 'search analytics');
-+----+-------------------------------------------+
-| id |                   data                    |
-+----+-------------------------------------------+
-| 2  | Inverted index accelerates full text search |
-| 4  | Full text search with inverted index      |
-| 5  | Data analytics on Lakehouse platform      |
-+----+-------------------------------------------+
-
---匹配短语，包含full text search且连续
-SELECT id, data FROM bulkload_data WHERE match_phrase(data, 'full text search');
-+----+-------------------------------------------+
-| id |                   data                    |
-+----+-------------------------------------------+
-| 2  | Inverted index accelerates full text search |
-| 4  | Full text search with inverted index      |
-+----+-------------------------------------------+
-```
-
-**等值查询示例：**
-
-```SQL
---使用倒排索引加速id列的等值查询
-SELECT id, data FROM bulkload_data WHERE id = 3;
-+----+------------------------------------------+
-| id |                   data                   |
-+----+------------------------------------------+
-| 3  | Lakehouse supports multiple data types   |
-+----+------------------------------------------+
-
---使用倒排索引加速id列的范围查询
-SELECT id, data FROM bulkload_data WHERE id >
-
-## 使用注意事项
-
-### 倒排索引无法优化场景
-
-* 在大多数情况下，倒排索引并不会显著提升亚秒级查询的性能。
-* 不支持外部表。
-* 仅支持数据类型一致的查询，例如：
-
-```SQL
---可以查询加速的，表中数据类型string
-where string_col='10086';
---对需要匹配的值进行转化
-where string_col=cast(10086 as string);
-
---无法查询加速的，因为对表列进行了强制转化
-where cast(string_col as int)=10086 ;
-```
-
-## 计费说明
-
-* 存储资源：倒排索引会在数据文件之外额外创建倒排索引文件，索引文件和数据文件将按照存储大小统一计收存储费用。

-# Lakehouse 倒排索引 BM25 参数调优
-
-BM25（Best Matching 25）是现代全文检索中最重要的相关性评分算法之一。Lakehouse 的倒排索引支持 BM25 算法，并允许用户调整关键参数以优化不同场景下的搜索效果。
-
-支持参数：
-
-`k1`  - 词频饱和度控制
-
-* **取值范围**:` [0.0, 3.0]`，推荐范围 `[1.0, 2.0]`
-
-* **默认值**: `1.2`
-
-* **作用**: 控制词频对相关性评分的影响程度
-
-* **效果**:
-
-  * **k1 越大**: 词频对评分的影响越大，高频词文档更容易获得高评分
-* **k1 越小**: 词频饱和更快，减少高频词的过度影响
-
-`b`  - 文档长度归一化
-
-* **取值范围**:` [0.0, 1.0]`
-
-* **默认值**: `0.75`
-
-* **作用**: 控制文档长度对相关性评分的影响程度
-
-* **效果**:
-
-  * **b = 0**: 完全忽略文档长度，长短文档同等对待
-  * **b = 1**: 完全长度归一化，短文档获得显著优势
-  * **b = 0.75**: 平衡长度影响，适合大多数场景
-
-在 Lakehouse 中，通过在 SQL 语句之前添加以下语句：
-
-```
-SET cz.storage.parquet.inverted.index.similarity.bm25={"k1": 1.2, "b": 0.75} 
-```
-
-实现对搜索效果的控制。

-# 倒排索引 multi-match 功能
-
-`multi-match` 是一种强大的查询功能，它允许用户将一个**单一的查询字符串**同时在**多个字段**上进行搜索。这在许多实际应用场景中都非常有用，例如，当一个电商网站的用户在搜索框输入 "durable backpack" 时，系统可能需要同时在 `product_title` (产品标题)、`description` (描述) 和 `category` (分类) 等多个字段中查找。
-
-当执行一个 multi-match 查询时，系统会在后台为指定的每一个字段执行匹配操作，然后将所有结果进行智能合并和排序，最终返回一个统一的相关度排序列表。
-
-^
-
-## 功能示例
-
-### 数据准备：
-
-测试数据表：
-
-```
-表名: dbpedia_entities_1m
-创建时间: 2025-07-03 12:07:32
-数据量: 1,000,000 行
-存储大小: 12.6 GB
-```
-
-表结构：
-
-* `id` (string) - 实体ID
-* `title` (string) - 实体标题
-* `text` (string) - 实体描述文本
-* `vec` (vector(float,1536)) - 1536维向量
-
-已构建索引如下：
-
-|                                    |          |       |         |                           |

-
-### 功能示例：
-
-#### 单列匹配
-
-在 `title` 字段搜索，要求 'Paris Wisconsin Foster' 匹配度超67%
-
-```SQL
-SELECT    
-    id,
-    title
-FROM dbpedia_entities_1m
-WHERE multi_match (
-            title,
-            'Paris Wisconsin Foster',
-            str_to_map('analyzer:unicode,minimum_should_match:67%')
-      );
-```
-
-![](.topwrite/assets/image_1753846662848.png)
-
-^
-
-#### 多字段联合搜索
-
-**三字段联合搜索 (ID + Title + Text)**
-
-在 ` id, title, text` 三个字段中搜索，要求查询词中至少有3个匹配
-
-```SQL
-SELECT    id,
-          title,
-          text
-FROM      dbpedia_entities_1m
-WHERE     multi_match (
-            id,
-            title,
-            text,
-            'French deaf Avenue_Q Robert driver',
-            str_to_map('analyzer:unicode,minimum_should_match:3')
-          );
-```
-
-**结果**：返回2条相关记录，内容语义匹配准确。

-## IS NULL
-
-`IS NULL` 子句用于在 `WHERE` 条件中判断列中的值是否为 `NULL`。`NULL` 表示该列没有值，或者值未知。需要注意的是，`NULL` 与空字符串或空格不同，后者是有具体值的。
-
-## 注意事项
-
-使用等号（`=`）来判断 `NULL` 是无法得到预期结果的，因为 `NULL` 不能用等号来比较。
-
-## 语法
-
-```sql
-SELECT * FROM table_name WHERE expression IS NULL;
-SELECT * FROM table_name WHERE expression IS NOT NULL;
-```
-
-其中，`expression` 是要判断的表达式，它可以是任意类型。`IS NULL` 和 `IS NOT NULL` 的返回值是布尔类型（`BOOLEAN`），如果 `expression` 的值为 `NULL`，则返回 `TRUE`，否则返回 `FALSE`。
-
-## 示例
-
-假设我们有一个名为 `student` 的表，其中包含以下数据：
-
-| id | name  | gender |
-|----|-------|--------|
-| 1  | Alice | F      |
-| 2  | Bob   | M      |
-| 3  | Cathy | F      |
-| 4  | David | NULL   |
-
-1. 现在，我们想要从 `student` 表中查询性别为 `NULL` 的学生，我们可以使用以下 SQL 语句：
-
-   ```sql
-   SELECT * FROM student WHERE gender IS NULL;
-   ```
-
-   结果集如下：
-
-   | id | name  | gender |
-   |---|-------|--------|
-   | 4  | David | NULL   |
-
-2. 如果我们想要查询性别不为 `NULL` 的学生，我们可以使用以下 SQL 语句：
-
-   ```sql
-   SELECT * FROM student WHERE gender IS NOT NULL;
-   ```
-
-   结果集如下：
-
-   | id | name  | gender |
-   |---|-------|--------|
-   | 1  | Alice | F      |
-   | 2  | Bob   | M      |
-   | 3  | Cathy | F      |
-
-## 常见问题
-
-Q: 为什么使用等号（`=`）判断 `NULL` 值无法得到预期结果？
-
-A: 这是因为 `NULL` 表示未知或缺失的值，所以它不能与任何值（包括 `NULL`）进行比较。使用等号（`=`）判断 `NULL` 值时，结果会是 `UNKNOWN`，而不是 `TRUE` 或 `FALSE`。因此，我们需要使用 `IS NULL` 或 `IS NOT NULL` 来判断 `NULL` 值。

-
-* [下载地址一](https://central.sonatype.com/artifact/com.clickzetta/clickzetta-java/versions)
-* [下载地址二](https://mvnrepository.com/artifact/com.clickzetta/clickzetta-java)
-
-### JDBC连接字符串
-
-使用JDBC驱动连接到Clickzetta Lakehouse时，JDBC连接字符串的语法格式如下：
-
-```
-jdbc:clickzetta://<instance_name>.<region_id>.api.clickzetta.com/<workspace_name>?<connection_params>
-```
-
-* 连接参数说明：
-
-  * `<instance_name>`：Lakehouse服务实例名称。在开通指定Region的Lakehouse服务实例时，系统会自动分配实例名称。您可以在产品控制台页面找到Lakehouse实例名称。
-
-  * `<region_id>`：服务实例所在的云厂商及区域的代码，如：cn-shanghai-alicloud。所有region\_id详见[云服务和地域](../Supported_Cloud_Platforms.md)。
-
-  * `<workspace_name>`：工作空间名称。
-
-  * `<connection_params>`：支持使用`=`格式定义参数，多个参数之间用`&`符号分隔。常用参数如下表所示：
-
-| 参数                                | 取值                                                                     |
-| --------------------------------- | ---------------------------------------------------------------------- |
-| username                          | Clickzetta登录用户名                                                        |
-| password                          | 登录用户密码                                                                 |
-| schema                            | 指定默认连接的schema，可选                                                       |
-| virtualCluster                    | 配置JDBC连接默认使用的虚拟集群，可选。如不选择指定，需要连接后通过SQL命令`use vcluster <vc_name>`指定方可使用 |
-| use\_http=true                    | 是否使用http协议，默认是https。当使用private link连接时需要指定该参数                          |
-| use\_oss\_internal\_endpoint=true | 是否使用http协议，默认是false。如果您使用的服务是阿里云支持查询时强制使用 OSS 内网 Endpoint。             |
-
-## 驱动类名
-
-`com.clickzetta.client.jdbc.ClickZettaDriver`
-
-## 初始化 JDBC 连接
-
-`clickzetta-java` 提供的 JDBC 驱动支持两种方式创建 Connection：
-
-1. 通过 JDBC URL 创建 Connection：
-   ```java
-   try {
-       Class.forName("com.clickzetta.client.jdbc.ClickZettaDriver");
-   } catch (ClassNotFoundException e) {
-       e.printStackTrace();
-       System.exit(1);
-   }
-   Connection conn = DriverManager.getConnection("jdbc:clickzetta://instance.api.clickzetta.com/workspace?schema=schema&vcluster=cluster", username, password);
-   ```
-
-* Lakehouse url可以在Lakehouse Studio管理-》工作空间中看到jdbc连接串以查看![](../.topwrite/assets/image_1739177196184.png)
-
-2. 通过 `ClickZettaClient` 创建 Connection：
-   ```java
-   ClickZettaClient client = ClickZettaClient.newBuilder()
-    .instance("instanceName")
-    .service("service")
-    .username("username")
-    .password("password")
-    .vcluster("cluster")
-    .schema("schema")
-    .build();
-   Connection conn = client.getJdbcConnection();
-   ```
-
-## 进行查询
-
-`clickzetta-java` 提供了完整的 JDBC 标准接口，您可以使用熟悉的 JDBC API 进行数据查询。以下是一些示例：
-
-### 示例 1：查询并打印结果
-
-```java
-import java.sql.Connection;

-            System.exit(1);
-        }
-        String jdbcUrl = args[0];
-        String username = args[1];
-        String password = args[2];
-
-        Connection conn = DriverManager.getConnection(jdbcUrl, username, password);
-        Statement stmt = conn.createStatement();
-        ResultSet resultSet = stmt.executeQuery("SELECT * FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live LIMIT 10");
-        ResultSetMetaData rsmd = resultSet.getMetaData();
-        int count = rsmd.getColumnCount();
-        while (resultSet.next()) {
-            for (int i = 1; i <= count; i++) {
-                System.out.print(rsmd.getColumnName(i) + ":" + resultSet.getObject(i) + " ");
-            }
-            System.out.println();

-## 实时写入原理
-
-实时写入Lakehouse的SDK是一种高效的数据流处理工具，它允许用户将数据实时地上传并存储到Lakehouse中。以下是实时写入的工作原理：
-
-1. **SDK上传数据**：用户通过SDK将数据实时上传到Lakehouse的Ingestion Service。
-2. **Ingestion Service处理**：Ingestion Service接收到数据后，直接将数据写入到Lakehouse的表中，此时数据以临时中间文件的形式存储，这个阶段称为**混合表**。
-3. **查询实时数据**：在数据提交之前，用户即可查询（select）到这些实时写入的新数据，但这些数据对于table stream、materialized view和dynamic table来说是不可见的。
-4. **数据提交**：新写入的数据会在大约一分钟后自动提交，提交后，table stream、materialized view和dynamic table都能够读取这部分数据。
-5. **混合表变成普通表**：在数据提交后，后台进程会将混合表合并变成普通表，合并完成后用户可以执行更新操作（update/merge/delete）。
-
-## 适用场景
-
-实时写入Lakehouse的SDK适用于以下场景：
-
-* **短间隔数据导入**：如果您的应用场景要求在非常短的时间间隔内（如5分钟或更短）导入数据，实时写入SDK可以满足您的需求。
-* **频繁小量数据提交**：对于需要频繁提交数据，但每次提交的数据量不大的情况，实时写入SDK提供了一个高效的解决方案。
-* **实时数据分析**：实时写入SDK适合需要对数据进行即时分析和响应的应用，例如实时监控、事件追踪和实时报告等。
-
-## 注意事项
-
-* 实时写入的数据可以秒级查询。
-* 实时写入数据目前只能通过内部提供的 Flink Connector 中支持 schema change 的 sink 算子（单并发）来实现实时的表结构变化感知。在其他场景下进行表结构更改时，需要先停止实时写入任务，然后在表结构变更后一段时间（大约90分钟）后，重新启动任务。
-* table stream、materialized view 和 dynamic table 只能显示已经提交的数据。实时任务写入的数据需要等待 1 分钟才能确认，因此 table stream 也需要等待 1 分钟才能看到。
-
-## 通过客户端创建实时数据流
-
-要创建实时数据流，首先需要使用 Lakehouse 客户端（client）：
-
-```java
-RowStream stream = client.newRealtimeStreamBuilder()
-.operate(RowStream.RealTimeOperate.APPEND_ONLY)
-.options(options)
-.schema(schema)
-.table(table)
-.build();
-// 关闭流，释放资源
-stream.close();
-```
-
-operate：传入一个枚举值，实时接口支持 RowStream.RealTimeOperate.APPEND\_ONLY 和 RowStream.RealTimeOperate.CDC。
-options：用于传入实时写入流的参数，具体见下文的 options 说明。
-
-## 选项（Options）
-
-可以将以下选项（options）传入到实时数据流中，用于控制写入数据的行为。这些参数均为选填，推荐使用默认参数。
-
-```SQL
-Options options = Options.builder()
-.withFlushMode(FlushMode.AUTO_FLUSH_BACKGROUND)
-            .withMutationBufferLinesNum(50000)
-            .withMutationBufferMaxNum(50)
-            .withMutationBufferSpace(20 * 1024 * 1024)
-            .withFlushInterval(10 * 1000)
-            .withRequestFailedRetryEnable(true)
-            .withRequestFailedRetryTimes(5)
-            .withRequestFailedRetryInternalMs(5 * 1000)
-            .withRequestFailedRetryLogDebugEnable(true)
-            .withRequestFailedRetryStatus(
-                    RegisterStatus.RetryStatus.THROTTLED,
-                    RegisterStatus.RetryStatus.INTERNAL_ERROR,
-                    RegisterStatus.RetryStatus.FAILED,
-                    RegisterStatus.RetryStatus.PRECHECK_FAILED)
-            .build();
-```
-
-**参数说明**
-
-| 类别 | 参数 | 默认值 | 说明 |
-| :--- | :--- | :--- | :--- |
-| 写入性能相关参数 | withFlushMode | FlushMode.AUTO_FLUSH_BACKGROUND | 数据刷写方式，目前支持：<br>FlushMode.AUTO_FLUSH_SYNC：每次等待上次刷新完成后才进行下一步写入。<br>FlushMode.AUTO_FLUSH_BACKGROUND：异步刷新，允许多个写入同时进行，不需要等待前一次写入完成。 |
-| 写入性能相关参数 | withMutationBufferLinesNum | 100 | 每个 buffer 中的数据条数的积攒限制，积攒达到后则会发送至服务端。当达到此限制时，数据将被实际 flush 提交至服务端。如果一次导入的数据量达到 MB 级别，可以调大此参数以加快导入速度。数据提交至服务端的条件是 MutationBufferLinesNum 或 withFlushInterval 中任意一个优先达到。 |
-|          | withMutationBufferMaxNum             | 5                                    | 在数据提交过程中，`withMutationBufferLinesNum` 指定了在达到一定数量的数据条目后进行发送，这是一个触发异步发送的阈值。而 `withMutationBufferMaxNum` 则定义了可以同时存在的缓冲区（buffer）的最大数量。即使前一个缓冲区的数据还未完全写入，只要缓冲区的数量没有超过 `withMutationBufferMaxNum` 指定的限制，就可以继续向新的缓冲区写入数据。这允许系统在处理和发送数据时实现更高的并发性，因为不必等待所有缓冲区都清空才能继续写入新数据。简而言之，`withMutationBufferMaxNum` 相当于jdbc连接池 |
-| 写入性能相关参数 | withMutationBufferSpace | 5 * 1024 * 1024 (5MB) | 当达到此限制时，数据将被实际 flush 提交至服务端。如果一次导入的数据量达到 MB 级别，可以调大此参数以加快导入速度。数据提交至服务端的条件是 withMutationBufferSpace 或 withMutationBufferLinesNum 中任意一个优先达到。 |
-| 写入性能相关参数 | withFlushInterval | 10 * 1000 (10秒) | 当达到此时间限制时，数据将被实际 flush 提交至服务端。数据提交至服务端的条件是 withMutationBufferSpace 或 withMutationBufferLinesNum 中任意一个优先达到。 |
-| 重试机制相关参数 | withRequestFailedRetryEnable | FALSE | 是否开启 mutate 失败重试机制。取值为 TRUE 或 FALSE。 |
-|          | withRequestFailedRetryTimes          | 5                                    | mutate 失败，重试最大次数。                                                                                                                                                                                                                                                                                           |
-| 重试机制相关参数 | withRequestFailedRetryInternalMs | 5000 (5秒) | 失败重试间隔时间，单位毫秒（ms）。 |
-|          | withRequestFailedRetryLogDebugEnable | FALSE                                | 是否开启debug日志                                                                                                                                                                                                                                                                                                 |
-|          | withRequestFailedRetryStatus         | RegisterStatus.RetryStatus.THROTTLED | 根据哪种错误原因进行重试，默认是RegisterStatus.RetryStatus.THROTTLED。多个值使用逗号隔开 取值 RegisterStatus.RetryStatus.THROTTLED RegisterStatus.RetryStatus.INTERNAL\_ERROR RegisterStatus.RetryStatus.FAILED RegisterStatus.RetryStatus.PRECHECK\_FAILED                                                                             |
-
-## 写入数据（Row）
-
-通过 `stream.createRow` 方法创建具体的数据对象（Row），并通过 `row.setValue` 方法将数据封装到 Row 对象中。
-
-**Row** **row** = stream.createRow(Stream.Operator.INSERT);
-
-row\.setValue("id", t);
-
-row\.setValue("name", String.valueOf(t));
-
-stream.apply(row);
-
-* 当 Stream 创建为 `RowStream.RealTimeOperate.APPEND_ONLY` 时，仅能创建 `Stream.Operator.INSERT` 类型的 Row。
-
-* 当 Stream 创建为 `RowStream.RealTimeOperate.CDC` 时，以下所有 Row 类型均可使用：
-
-  * `Stream.Operator.INSERT`：插入行，如果目标行已存在则报错。
-  * `Stream.Operator.DELETE`：删除行，如果目标行不存在则报错。
-  * `Stream.Operator.UPDATE`：更新行，如果目标行不存在则报错。
-  * `Stream.Operator.UPSERT`：插入行，如果目标行已存在则更新该行。
-  * `Stream.Operator.INSERT_IGNORE`：插入行，如果目标行已存在则自动忽略。
-
-## 数据提交到服务端
-
-通过调用 `((RealtimeStream)stream).flush()` 方法，数据会提交到服务端。如果没有调用该方法，则数据根据 withMutationBufferSpace、withMutationBufferLinesNum 或 withFlushInterval 中任意一个条件优先达到时，数据将被发送到服务端。
-

-## 写入vector类型
-
-创建表
-
-```
-CREATE TABLE test\_vector (
-vec1 vector(float, 512), -- 指定元素类型为float，维度为512
-vec2 vector(512), -- 默认元素类型为float，维度为512
-vec3 vector(tinyint, 128) -- 指定元素类型为tinyint，维度为128
-
-);
-```
-
-使用Java写入
-
-```Java

-## CDC实时写入
-
-Lakehouse支持数据库的CDC（Change Data Capture）功能，以流的方式将数据写入到Lakehouse表中，并实时更新表数据。同步过程通过RealtimeStream实时更新插入和删除行操作来实现。同时，支持使用Flink connector和IGS SDK进行数据写入。在创建表时，需要设置主键以确保数据的唯一性和一致性。
-
-### 创建表
-
-在创建Lakehouse表时，需要指定主键。CDC写入会根据主键进行数据去重，以确保数据的准确性。虽然创建的主键表支持SQL操作，建议通过实时写入流进行数据写入。以下是一个创建表的示例：
-
-```sql
-CREATE TABLE igs_test_upsert (
-    id INT PRIMARY KEY,
-    event VARCHAR(100),
-    event_time STRING
-);
-```
-
-### IGS SDK实时写入流
-
-#### 创建实时写入流
-
-使用IGS SDK创建实时写入流，需要指定操作类型（CDC）和相关选项。以下是一个创建实时写入流的示例：
-
-```java
-RowStream stream = client.newRealtimeStreamBuilder()
-    .operate(RowStream.RealTimeOperate.CDC)
-    .options(options)
-    .schema(schema)
-    .table(table)
-    .build(); // 关闭流，释放流资源，必须调用
-stream.close();
-```
-
-#### 指定操作类型
-
-根据需求，可以指定不同的操作类型：
-
-* `Stream.Operator.UPSERT`：插入或更新行。如果目标行不存在，则插入；如果已存在，则更新。
-* `Stream.Operator.DELETE_IGNORE`：删除行。如果目标行不存在，则自动忽略。
-
-#### 使用原生Java Sdk写入
-
-```java
-Row row = stream.createRow(Stream.Operator.UPSERT); // 插入或更新行
-Row rowToDelete = stream.createRow(Stream.Operator.DELETE_IGNORE); // 删除行
-```
-
-### 使用Lakehouse实时同步功能写入
-
-参考文档[多表实时同步](../realtime_sync.md)
-
-### 使用FLINK CONNECTOR写入
-
-Flink connector是基于RealtimeStream SDK封装的，用于实现实时数据同步。查看[Flink Connector](../flink-write-connector.md)

-
-### 分析频率建议
-
-* **每日监控**: 执行总体概览和失败作业分析
-* **每周分析**: 运行完整的忙闲程度和表使用分析
-* **每月评估**: 进行缓存效率和资源规划分析
-
-建议将常用查询保存为视图，便于重复使用。
-
-### 优化行动指南
-
-* **高执行时间作业**: 检查SQL优化机会，尝试用Dynamic Table的增量计算链路降低计算量，减少执行时间；
-* **低缓存命中率**: 调整分析型计算集群的自动关机时间，在查询高峰期尽量不关机，避免丢失缓存；
-* **高频访问表**: 考虑分区、索引优化；
-* **资源不均衡**: 重新分配workspace内的计算集群资源规格，对频繁使用的计算集群，如果希望降低作业执行时间，可以适当扩容。

-Lakehouse 作业历史页面（Job Profile）为您提供了一个直观的方式来查看过去 7 天内在 Lakehouse 账户中执行的查询的详细信息。您可以通过该页面查看包括使用 JDBC 接口提交的任务、Studio 临时查询、Studio 周期调度任务在内的历史作业列表。本指南将帮助您分析运行出错或运行缓慢的作业，并提供相应的解决方案。
-
-## 作业历史搜索
-
-* 支持根据 SQL 作业的作业 ID 进行搜索。
-* 支持根据状态搜索：
-  * setup: SQL 初始化阶段，包含编译优化等操作。
-  * resuming_cluster: 等待启动 VC 耗时，如果长时间未拉起，请联系技术支持。
-  * queued: 作业排队等待资源，如果耗时较长，建议查看 VC 资源是否占满，或考虑扩容 VC。
-  * running: SQL 处理数据时间，可以点击诊断查看每个算子耗时。
-  * finish: 运行结束，部分作业可能在这一阶段进行清理过程，会产生耗时。
-* 支持按耗时筛选
-* 支持按时间筛选，目前最多能查询到近七天的 10,000 条作业。
-* 支持按作业运行的集群名称进行筛选
-* 支持按作业的提交人进行筛选
-* 支持根据 queryTag 筛选
-  用户在提交 SQL 时，可以通过命令 `set query_tag=""` 来标记作业来源或为作业打标，并在此界面进行过滤。
-  * 在 Studio 界面设置 query_tag，选中两条 SQL 同时执行：
-  ```SQL
-      set query_tag="test";
-      select 1;
-  ```
-  * 在 JDBC URL 中添加 query_tag，这样提交的每条 SQL 都会带上 query_tag 用来标识来源，可以在页面中进行过滤。
-  ```text
-  jdbc:clickzetta://instance.region_id.api.clickzetta.com/default?schema=public&query_tag=test
-
-  ```
-  * 在 Python 代码中设置 query_tag
-  ```python
-  # 建立连接 
-  conn = connect(username='',
-   password='', 
-  service='region_id.api.clickzetta.com', 
-  instance='demo_instance',
-   workspace='', schema='public', vcluster='default') 
-  # 执行 SQL 
-  cursor = conn.cursor() 
-  my_param["hints"]["query_tag"] ="test"
-  cursor.execute('select 1;', parameters=my_param)
-
-  ```
-* 作业的默认 Schema（即提交 SQL 时运行的上下文环境），可以通过 `select current_schema()` 获取。
-
-## 分析运行出错的作业
-
-当作业运行失败时，您可以通过作业的 Job Profile 中的详情来查看失败原因。以下是一些常见的失败原因及解决方法：
-
-### SQL语法错误
-
-**错误示例**：
-
-```SQL
-执行 select * from ttt;
-报错 :CZLH-42000:[1,15] Semantic analysis exception - table or view not found - uat_demo_project.`public`.ttt
-```
-
-**错误码 CZLH-42000** 表示与 SQL 语言解析相关的错误。[1,15] 表示错误发生在 SQL 的第 1 行第 15 列。在这个例子中，原因是 `ttt` 表不存在。请注意，如果您通过 Studio 开发界面提交任务，由于开发中的作业编辑器会带有描述信息，这些信息并不会提交到 SQL 引擎，因此正确的行号应该减去前面的描述信息行数。您可以通过作业详情中的作业内容查看正确的位置关系，或者在 SQL 编辑器中找到错误的位置。
-
-## 分析运行缓慢的作业
-
-运行缓慢的作业可能在编译阶段、Virtual Cluster 拉起阶段或执行阶段出现问题。以下是针对这些阶段的分析和解决方法：
-
-### 编译阶段
-
-**问题现象**：作业状态显示为“初始化”。
-
-**可能原因及解决措施**：
-
-1. **执行计划复杂**：作业可能需要较长时间进行优化。请耐心等待，正常情况下不会超过 10 分钟。
-2. **编译资源被占满**：如果您一瞬间提交了大量 SQL，可能导致编译资源不足。请减少提交 SQL 的频率。如有大量高并发查询需求，请提交工单寻求帮助。
-
-### 拉起virtual cluster阶段
-
-**问题现象**：作业状态显示为“集群启动中”。（当前状态为正在拉起计算集群）
-
-### 等待执行阶段
-
-**问题现象**：作业状态显示为“等待执行”。
-
-**可能原因及解决措施**：
-1.  **当前集群的计算资源不足**：您可以通过界面筛选查看当前正在运行的作业。可能因大量作业正在运行导致资源等待。可以考虑扩容资源，或者终止正在运行的大作业以释放资源。
-
-### 执行阶段
-
-**问题现象**：作业状态显示为“正在执行中”。在这一阶段，您可以点进去查看每个算子的执行情况。
-
-**可能原因及解决措施**：
-1.  **等待资源**：作业可能在等待资源分配。请检查资源使用情况，如有需要，请提交工单寻求帮助。
-2.  **数据读取速度慢**：作业可能因为数据读取速度慢而导致执行缓慢。请检查数据存储和读取策略，如有需要，请优化数据存储结构或调整读取策略。
-
-### 分享给其他人诊断
-
-进入作业详情页面后，点击“分享”按钮，即可将作业分享给其他人。接收者无需登录即可查看内容。![](.topwrite/assets/image_1740557522715.png =774)
-如有疑问或需要进一步帮助，请复制上方链接并联系 Lakehouse 团队，我们将为您诊断并解决问题。
-
-## 查看执行计划和Operator详情
-
-在执行阶段，您可以通过点击正在执行的 Operator 来查询具体的步骤和策略。例如，将鼠标悬停在具体的 Operator 上，可以对应到 SQL 中具体执行的算子。这有助于您发现具体是哪个 Operator 导致作业缓慢。

-# JSON数据格式简介
-
-JSON（JavaScript Object Notation）是一种轻量级、易于阅读和编写的半结构化数据格式。它基于JavaScript的一个子集，但是JSON是独立于语言的，许多编程语言都有JSON数据格式的解析和生成代码。JSON格式使用文本表示简单的数据结构，如对象、数组、字符串、数字和布尔值。JSON格式具有良好的可读性和简洁性，使其成为理想的数据交换格式。
-
-# LakeHouse中的JSON类型
-
-在LakeHouse中，JSON类型的数据可以高效地存储和查询。JSON数据在LakeHouse中会被解析，并根据数据的实际结构进行优化存储。以下是LakeHouse中JSON类型的一些特点：
-
-1. 查询性能：使用JSON类型相比于String类型在查询性能上有明显优势，因为LakeHouse会对JSON数据进行列裁剪，减少不必要的数据扫描。
-2. 数据重排：解析过程中，JSON对象的数据可能会被重新排序，因此输入和输出的JSON数据可能在键的顺序上不一致。
-3. 数字解析：解析JSON数字时，LakeHouse会优先尝试将其解析为bigint类型。如果数字超出bigint的范围，则会将其解析为double类型。需要注意的是，double类型可能会有精度损失。
-4. 错误处理：使用函数解析JSON数据时，LakeHouse会进行校验。对于非法的JSON字符串，会返回NULL值；而在声明JSON常量时，非法的JSON字符串会导致错误。
-
-此外，LakeHouse在写入过程中会根据实际的JSON Schema，将出现频次高的字段按照列存储的方式存储，以提高存储和查询效率。例如：
-
-```SQL
-CREATE TABLE json_table AS
-SELECT  parse_json(s) as j
-FROM VALUES
-('{"id": 1, "value": "200"}'),
-('{"id": 2, "value": "300"}'),
-('{"id": 3, "value": "400", "extra": 1}'),
-('{"value": "100"}') as t(s);
-```
-
-1. 对于上面的数据，LakeHouse 检测出 id 和 value 出现频次高，分别适合用 bigint 和 string 类型列式存储，则会在内部以类似 struct\<id:bigint, value:string> 的结构存储。在后续的查询过程中，如果只读取id字段且转换为bigint，如`SELECT json_extract_bigint(j, '$.id')`，则可以直接按列读取 id 字段，并消除类型转换的开销。
-2. 对于出现频次低的 extra 字段，则保留 json 结构且用更加紧凑的表示存储，避免产生过于稀疏的数据。
-
-**限制**
-
-* 不支持对JSON类型的比较操作，也不支持对JSON类型进行`ORDER BY`、`GROUP BY`或作为`JOIN`的key等。
-* 不支持作为cluster key、primary key、partition key
-* JSON字符串最大长度为16 MB。批量、实时导入时对字段进行长度校验。如果您导入数据时有大于16MB的数据您可以修改表的Properties来修改如下将json长度设置为32MB
-
-```
-ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.json.bytes"="33554432");
-```
-
-## 创建JSON列的表
-
-要创建包含JSON类型列的表，可以使用以下SQL语句：
-
-```sql
-CREATE TABLE json_example
-(
-    id bigint,
-    data json
-);
-```
-
-## 构建JSON数据
-
-### JSON常量
-
-在SQL查询中，可以使用JSON常量来表示JSON数据。例如：
-
-```sql
-SELECT
-JSON 'null',
-JSON '1',
-JSON '3.14',
-JSON 'true',
-JSON 'false',
-JSON '{"id":11,"name":"Lakehouse"}',
-JSON '[0, 1]';
-
--- !query output
-+-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
-| JSON 'null' | JSON '1' | JSON '3.14' | JSON 'true' | JSON 'false' | JSON '{"id":11,"name":"Lakehouse"}' | JSON '[0, 1]' |
-+-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
-| null        | 1        | 3.14        | true        | false        | {"id":11,"name":"Lakehouse"}        | [0,1]         |
-+-------------+----------+-------------+-------------+--------------+-------------------------------------+---------------+
-```
-
-### 语法
-
-```SQL
---键名访问JSON对象中的字段
-json_column['key']['key']...
---通过索引访问JSON数组中的元素
-json_array[index]
-```
-
-**参数说明**
-
-* json\_column:表示一个JSON字段，类型为JSON对象。通过键名（`key`），指定为字符串，来定位并检索JSON对象内的特定数据字段。使用单个方括号`[]`可以访问对象的一级字段；而嵌套使用双方括号`[][]`则能够深入检索对象的二级或更深层次的字段。
-* json\_array:数组类型的JSON，用来根据index访问 JSON array的元素，起始值为0
-

-
-```SQL
-SELECT parse_json(s)['firstName'] as j
-      FROM VALUES ('{ "firstName": "John", "lastName": "doe", "age": 26, "address": { "streetAddress": "naist street", "city": "Nara", "postalCode": "630-0192" }, "phoneNumbers": [ { "type": "iPhone", "number": "0123-4567-8888" }, { "type": "home", "number": "0123-4567-8910", "extra": [] } ] }'),
-                  ('{ "firstName": "Ada", "lastName": "doe", "age": 20, "address": { "streetAddress": "naist street", "city": "Nara", "postalCode": "630-0192" }, "address2": {"city": "NewYork"}, "phoneNumbers": [ { "type": "iPhone", "number": "0123-4567-8888" }, { "type": "home", "number": "0123-4567-8910", "extra": [1,2,3] } ] }')
-                 as t(s);
-```
-
-取出json二级结构
-
-```SQL
-SELECT parse_json(s)['address']['streetAddress'] as j
-      FROM VALUES ('{ "firstName": "John", "lastName": "doe", "age": 26, "address": { "streetAddress": "naist street", "city": "Nara", "postalCode": "630-0192" }, "phoneNumbers": [ { "type": "iPhone", "number": "0123-4567-8888" }, { "type": "home", "number": "0123-4567-8910", "extra": [] } ] }'),
-                  ('{ "firstName": "Ada", "lastName": "doe", "age": 20, "address": { "streetAddress": "naist street", "city": "Nara", "postalCode": "630-0192" }, "address2": {"city": "NewYork"}, "phoneNumbers": [ { "type": "iPhone", "number": "0123-4567-8888" }, { "type": "home", "number": "0123-4567-8910", "extra": [1,2,3] } ] }')
-                 as t(s);
-```
-
-取出json数组中的元素
-
-```SQL
-SELECT parse_json(s)['phoneNumbers'][0]['number'] as j
-      FROM VALUES ('{ "firstName": "John", "lastName": "doe", "age": 26, "address": { "streetAddress": "naist street", "city": "Nara", "postalCode": "630-0192" }, "phoneNumbers": [ { "type": "iPhone", "number": "0123-4567-8888" }, { "type": "home", "number": "0123-4567-8910", "extra": [] } ] }'),
-                  ('{ "firstName": "Ada", "lastName": "doe", "age": 20, "address": { "streetAddress": "naist street", "city": "Nara", "postalCode": "630-0192" }, "address2": {"city": "NewYork"}, "phoneNumbers": [ { "type": "iPhone", "number": "0123-4567-8888" }, { "type": "home", "number": "0123-4567-8910", "extra": [1,2,3] } ] }')
-                 as t(s);
-```
-
-### 使用函数
-
-### 使用函数(将STRING格式的JSON转化为字符串)
-
-`parse_json`函数可以将String类型的JSON字符串解析为JSON类型。例如：
-
-```SQL
-SELECT parse_json(s) is null, parse_json(s)
-FROM VALUES ('null'),
-            ('1'),
-            ('3.14'),
-            ('true'),
-            ('false'),
-            ('{"id":11,"name":"Lakehouse"}'),
-            ('[0, 1]'),
-            (''),
-            ('invalid') as t(s);
-+-------------------------+------------------------------+
-| (parse_json(s)) IS NULL |        parse_json(s)         |
-+-------------------------+------------------------------+
-| false                   | null                         |
-| false                   | 1                            |
-| false                   | 3.14                         |
-| false                   | true                         |
-| false                   | false                        |
-| false                   | {"id":11,"name":"Lakehouse"} |
-| false                   | [0,1]                        |
-| true                    | null                         |
-| true                    | null                         |
-+-------------------------+------------------------------+
-```
-
-* 如果parse\_json的参数为非法json字符串，则返回SQL null，is null的结果为true
-* 如果输入字符串为`'null'`，则它会被解释为JSON null值，is null的结果为false
-
-### json\_array/json\_object
-
-类似array/named\_struct，可以根据已有的数据构造出对应的json类型
-
-```SQL
-SELECT json_array(), json_array(NULL),json_array(NULL::int, 1, TRUE, FALSE, NULL::int, "a", 1.2, 1.3d);
-+----------------+--------------------+--------------------------------------------------------------------------------------+
-| `json_array`() | `json_array`(NULL) | `json_array`(CAST(NULL AS int), 1, true, false, CAST(NULL AS int), 'a', 1.2BD, 1.3d) |
-+----------------+--------------------+--------------------------------------------------------------------------------------+
-| []             | [null]             | [null,1,true,false,null,"a","1.2",1.3]                                               |
-+----------------+--------------------+--------------------------------------------------------------------------------------+
-
-SELECT json_object(), json_object('k', NULL), json_object('k1', json_array(1, "a"), "k2", array(1, 2, 3));
--- !query output
-+-----------------+--------------------------+-------------------------------------------------------------------+
-| `json_object`() | `json_object`('k', NULL) | `json_object`('k1', `json_array`(1, 'a'), 'k2', `array`(1, 2, 3)) |
-+-----------------+--------------------------+-------------------------------------------------------------------+
-| {}              | {"k":null}               | {"k1":[1,"a"],"k2":[1,2,3]}                                       |
-+-----------------+--------------------------+-------------------------------------------------------------------+
-```
-
-## 类型转换
-
-在LakeHouse中，可以使用`::json`或`CAST`函数将其他类型转换为JSON类型。以下是一些类型转换的例子：
-
-|            |               |
-| ---------- | ------------- |
-| Json       | SQL           |
-| Object     | Struct        |
-| Array      | Array         |
-| String     | string        |
-| Number     | bigint/double |
-| true/false | bool          |
-| Null       | 无对应类型         |
-| 无对应类型      | binary        |
-
-* 不存在于表格中的类型转换，会先将其转换为可以转换的类型（大多数情况为string类型），再转换为目标类型，例如cast(1.2 as json) 1.2为decimal类型，会先转换为string类型，进一步转换为json类型，结果是JSON '"1.2"'，而不是JSON '1.2'。
-* 需要注意的是cast(string as json)的语义和parse\_json(string)的语义并不一致,parse\_json 会尝试将 JSON 字符串解析成 JSON 对象，如果JSON格式不正确，则会生成 NULL而cast(string to json)**会将字符串整体当做JSON中的string类型,所以如果您是一个json格式字符串转化时应该使用parse\_json**

-```
-
-需要注意的是，`cast(string as json)`和`parse_json(string)`的语义并不一致。`parse_json`会尝试将JSON字符串解析成JSON对象，如果JSON格式不正确，则会生成NULL；而`cast(string to json)`会将字符串整体当做JSON中的string类型。
-
-```SQL
-SELECT parse_json(s), s::json, s::json::string
-FROM VALUES ('{"id":11, "name": "Lakehouse"}') as t(s);
-+------------------------------+----------------------------------------+---------------------------------+
-|        parse_json(s)         |            CAST(s AS json)             | CAST(CAST(s AS json) AS string) |
-+------------------------------+----------------------------------------+---------------------------------+
-| {"id":11,"name":"Lakehouse"} | "{\"id\":11, \"name\": \"Lakehouse\"}" | {"id":11, "name": "Lakehouse"}  |
-+------------------------------+----------------------------------------+---------------------------------+
-```
-
-# 使用SDK（igs/bulkload）写入JSON
-
-Lakehouse 支持给 JSON 类型的列写入 String 类型的字符串，系统在导入的时候会自动将字符串解析成 JSON 类型，如果用户输入了不符合 JSON 规范或者 CZ 不支持的 JSON 字符串，系统会报错并停止导入。
-
-# 导出JSON数据
-
-Lakehouse 支持以字符串的形式导出 JSON 数据。
-
-# 查询JSON数据
-
-查询JSON数据需要使用`json_extract`系列函数，通过JSON path获取需要的数据。以下是一些查询JSON数据的例子：
-
-* json\_extract
-* json\_extract\_boolean
-* json\_extract\_float
-* json\_extract\_double
-* json\_extract\_int
-* json\_extract\_bigint
-* json\_extract\_string
-* json\_extract\_date
-* json\_extract\_timestamp
-
-### json path规范
-
-json\_extract的第二个参数为json path，可以参考[json path规范](https://goessner.net/articles/JsonPath/)
-
-* "$"表示根元素
-* ".key"或者"\['key']" 用来查找json object中的key。特殊的，"\[\*]"表示获取所有的value,要求必须是单引号
-* "\[index]" 用来根据index访问 json array的元素，起始值为0。特殊的，"\[\*]"表示所有的元素
-
-```SQL
-SELECT json_extract(j, "$[0]"),
-       json_extract(j, "$[1]"),
-       json_extract(j, "$[*]")
-FROM VALUES (JSON '["a", 1, null]') as t(j);

-
-# 其他JSON函数
-
-json\_valid用来验证一个string类型的数据是否可以转换为json类型
-
-```SQL

-# 性能对比
-
-构造的数据为1000多万条这样格式`{"address":"89695 Lind Common, Kellymouth, AK 61747","email":"``danita.weber@gmail.com``","name":"Golda Shields"}`，使用where进行过滤查询
-
-使用string查询，执行时间为20.4s。
-
-```SQL
-create table bulkload_data_string(data string);
-select get_json_object(data,'$.email') from bulkload_data_string where get_json_object(data,'$.email')='danita.weber@gmail.com'
-;
-```
-
-![](.topwrite/assets/image_1712910635623.png)
-
-使用json存储数据执行时间为531ms,因为读取的时候进行列裁剪数据大小也会减少,如下图只需要读取153MB数据，string类型需要全量读取454MB数据
-
-```SQL
-create table bulkload_data(json string);
-select json_extract_string(data,'$.name') from bulkload_data where json_extract_string(data,'$.email')='danita.weber@gmail.com'

-## JSON数据类型概述
-
-### 核心优势
-
-云器 Lakehouse 的 JSON 类型相比字符串存储具有显著优势：
-
-1. **查询性能提升**：JSON 列支持列裁剪，只读取需要的字段，性能提升可达 40 倍
-2. **智能存储优化**：高频字段自动列式存储，低频字段紧凑 JSON 存储
-3. **自动类型推断**：数字优先解析为 bigint，超出范围自动转为 double
-4. **原生函数支持**：丰富的 json_extract_* 函数系列，类型安全转换
-
-### 数据存储机制
-
-```sql
--- 云器Lakehouse自动优化存储策略
-CREATE TABLE user_profiles (
-    id INT,
-    profile JSON  -- 智能存储：高频字段列式，低频字段JSON
-);
-
--- 内部优化示例：
--- 高频字段如 id, name 自动列式存储
--- 低频字段如 extra_metadata 保持JSON结构
-INSERT INTO user_profiles VALUES 
-(1, parse_json('{"id": 1, "name": "张三", "age": 30, "extra_metadata": {"hobby": "篮球"}}')),
-(2, parse_json('{"id": 2, "name": "李四", "age": 25, "city": "上海"}')),
-(3, parse_json('{"id": 3, "name": "王五", "age": 35, "department": "技术部"}'));
-```

-
-***
-
-## 基础语法
-
-### 创建JSON表
-
-```sql
--- 基础JSON表结构
-CREATE TABLE json_example (
-    id INT,
-    data JSON,           -- 原生JSON类型
-    data_str STRING      -- 字符串形式的JSON（对比用）
-);
-```
-
-### 插入JSON数据
-
-```sql
--- 方法1：使用parse_json函数（推荐）
-INSERT INTO json_example VALUES (
-    1, 
-    parse_json('{"name": "张三", "age": 30, "city": "北京"}'),
-    '{"name": "张三", "age": 30, "city": "北京"}'
-);
-
--- 方法2：使用json_object构建
-INSERT INTO json_example VALUES (
-    2,
-    json_object('name', '李四', 'age', 25, 'hobbies', json_array('篮球', '旅游')),
-    null
-);
-
--- 方法3：直接使用JSON字面量
-INSERT INTO json_example VALUES (
-    3,
-    json'{"name": "王五", "age": 35, "address": {"city": "上海", "zipcode": "200000"}}',
-    null
-);
-```
-

-
-## JSON vs STRING对比
-
-### 性能对比（官方测试数据）
-
-基于云器 Lakehouse 官方 1000 万条记录的性能测试：
-
-| 操作类型   | STRING 存储 | JSON 存储 | 性能提升      |
-| ------ | -------- | ------ | --------- |
-| 字段过滤查询 | 20.4 秒    | 531 ms  | **38 倍**   |
-| 数据扫描量  | 454 MB    | 153 MB  | **66% 减少** |
-| 存储空间   | 100%     | ~80%  | **20% 节省** |
-
-### 函数使用区别
-
-```sql
--- ❌ 错误：在JSON类型上使用STRING函数
-SELECT get_json_object(json_column, '$.name') FROM table_with_json;
--- 错误：function 'get_json_object' cannot be resolved, invalid type 'json'
-
--- ✅ 正确：JSON类型使用json_extract_*系列
-SELECT json_extract_string(json_column, '$.name') FROM table_with_json;
-
--- ✅ 正确：STRING类型使用get_json_object
-SELECT get_json_object(string_column, '$.name') FROM table_with_string;
-```

-## 按平台的迁移指南
-
-### Apache Spark/Hive 用户 ⭐⭐⭐⭐⭐
-
-**兼容性：几乎完美！零学习成本！**
-
-#### ✅ 完全支持的功能
-
-```sql
--- 1. Spark风格的JSON构建和解析
-SELECT 
-    to_json(map('name', '张三', 'age', 30)) as spark_json,
-    from_json('{"name":"张三","age":30}', 'name STRING, age INT') as spark_struct;
-
--- 2. collect_list聚合（Spark用户最爱）
-SELECT 
-    department,
-    collect_list(name) as employee_names
-FROM employee_json
-GROUP BY department;
-
--- 3. explode展开JSON数组
-SELECT 
-    id,
-    hobby
-FROM json_table 
-LATERAL VIEW explode(split(regexp_replace(
-    json_extract_string(json_data, '$.hobbies'), '[\\[\\]"]', ''), ',')) t AS hobby;
-
--- 4. 窗口函数完美支持
-SELECT 
-    name,
-    salary,
-    row_number() OVER (PARTITION BY department ORDER BY salary DESC) as rank
-FROM employee_json;
-
--- 5. Hive json_tuple完全兼容
-SELECT 
-    name, age, city
-FROM (
-    SELECT json_tuple(json_string, 'name', 'age', 'city') as (name, age, city)
-    FROM hive_json_table
-) t;
-```
-
-#### 📝 Spark/Hive用户最佳实践
-
-```sql
--- ✅ 推荐的迁移模式
-CREATE TABLE lakehouse_events (
-    event_id STRING,
-    event_data JSON,
-    
-    -- 生成列：熟悉的字段提取
-    event_type STRING GENERATED ALWAYS AS (json_extract_string(event_data, '$.type')),
-    user_id STRING GENERATED ALWAYS AS (json_extract_string(event_data, '$.user_id')),
-    timestamp_col TIMESTAMP GENERATED ALWAYS AS (
-        cast(json_extract_string(event_data, '$.timestamp') as timestamp)
-    )
-) PARTITIONED BY (event_type);
-
--- 直接复制Hive查询，无需修改！
-CREATE TABLE lakehouse_table AS 
-SELECT 
-    get_json_object(json_col, '$.user.id') as user_id,
-    get_json_object(json_col, '$.user.name') as user_name,
-    get_json_object(json_col, '$.event.type') as event_type
-FROM source_table
-WHERE get_json_object(json_col, '$.event.type') = 'purchase';
-```
-
-### Snowflake 用户 ⭐⭐
-
-**兼容性：需要重写，但有明确的替代方案**
-
-#### 🔄 Snowflake迁移示例
-
-```sql
--- ❌ Snowflake原始查询
--- SELECT 
---     user_data:name::STRING as name,
---     user_data:age::INTEGER as age,
---     user_data:hobbies[0]::STRING as first_hobby
--- FROM snowflake_table;
-
--- ✅ 云器Lakehouse等价查询
-SELECT 
-    json_extract_string(user_data, '$.name') as name,
-    json_extract_int(user_data, '$.age') as age,
-    json_extract_string(user_data, '$.hobbies[0]') as first_hobby
-FROM lakehouse_table;
-
--- ❌ Snowflake FLATTEN
--- SELECT 
---     value::STRING as hobby
--- FROM snowflake_table,
--- LATERAL FLATTEN(input => user_data:hobbies);
-
--- ✅ 云器Lakehouse等价方案
-SELECT 
-    trim(hobby) as hobby
-FROM lakehouse_table 
-LATERAL VIEW explode(
-    split(regexp_replace(json_extract_string(user_data, '$.hobbies'), '[\\[\\]"]', ''), ',')
-) t AS hobby;
-```
-
-### PostgreSQL/MySQL 用户 ⭐⭐⭐
-
-**兼容性：函数不同，但逻辑相同**
-
-#### PostgreSQL迁移示例
-
-```sql
--- ❌ PostgreSQL原始查询
--- SELECT 
---     user_data ->> 'name' as name,
---     (user_data -> 'address' ->> 'city') as city,
---     user_data #>> '{preferences,0}' as first_pref
--- FROM postgres_table;
-
--- ✅ 云器Lakehouse等价查询
-SELECT 
-    json_extract_string(user_data, '$.name') as name,
-    json_extract_string(user_data, '$.address.city') as city,
-    json_extract_string(user_data, '$.preferences[0]') as first_pref
-FROM lakehouse_table;
-```
-
-#### MySQL迁移注意事项
-
-```sql
--- ❌ MySQL方式（针对字符串）
--- SELECT JSON_EXTRACT(json_string, '$.name') FROM mysql_table;
-
--- ✅ 云器Lakehouse方式（区分类型）
--- 对于STRING类型
-SELECT get_json_object(json_string, '$.name') FROM lakehouse_table;
-
--- 对于JSON类型  
-SELECT json_extract_string(json_data, '$.name') FROM lakehouse_table;
-```

-
-## JSON函数完全指南
-
-### 1. JSON构建函数
-
-```sql
--- json_object：构建JSON对象
-SELECT json_object() as empty_obj;                    -- {}
-SELECT json_object('key', 'value') as simple_obj;     -- {"key":"value"}
-SELECT json_object(
-    'name', '张三',
-    'age', 30,
-    'hobbies', json_array('篮球', '旅游')
-) as complex_obj;
--- {"age":30,"hobbies":["篮球","旅游"],"name":"张三"}
-
--- json_array：构建JSON数组
-SELECT json_array() as empty_arr;                     -- []
-SELECT json_array(1, 2, 3) as number_arr;             -- [1,2,3]
-SELECT json_array('a', 'b', 'c') as string_arr;       -- ["a","b","c"]
-SELECT json_array(1, 'test', true, null) as mixed_arr; -- [1,"test",true,null]
-```
-
-### 2. JSON路径语法
-
-```sql
--- 基础路径语法
-'$'                    -- 根元素
-'$.field'              -- 对象字段
-'$.nested.field'       -- 嵌套对象字段
-'$[0]'                 -- 数组第一个元素
-'$[*]'                 -- 数组所有元素
-'$.array[0].field'     -- 数组元素的字段
-'$["key.with.dot"]'    -- 包含特殊字符的键（使用单引号）
-
--- 实际示例
-SELECT 
-    json_extract_string(data, '$.name') as name,
-    json_extract_string(data, '$.address.city') as city,
-    json_extract_string(data, '$.hobbies[0]') as first_hobby,
-    json_extract(data, '$.hobbies[*]') as all_hobbies
-FROM json_table;
-```
-
-### 3. JSON验证和错误处理
-
-```sql
--- json_valid：验证JSON格式
-SELECT 
-    json_valid('{"name": "test"}') as valid,      -- true
-    json_valid('invalid json') as invalid,       -- false
-    json_valid('null') as null_valid,             -- true
-    json_valid('[]') as array_valid,              -- true
-    json_valid('{}') as object_valid;             -- true
-
--- 错误处理：不存在的字段返回null
-SELECT 
-    json_extract_string(data, '$.nonexistent') as result  -- 返回 null
-FROM json_table;
-```
-
-***
-
-## JSON与生成列
-
-### 基础用法
-
-```sql
--- 创建带JSON生成列的表
-CREATE TABLE user_analytics (
-    id INT,
-    user_data JSON,
-    -- 生成列：自动提取JSON字段
-    user_name STRING GENERATED ALWAYS AS (
-        json_extract_string(user_data, '$.name')
-    ),
-    user_age INT GENERATED ALWAYS AS (
-        json_extract_int(user_data, '$.age')
-    ),
-    city STRING GENERATED ALWAYS AS (
-        json_extract_string(user_data, '$.address.city')
-    )
-) COMMENT 'JSON自动字段提取示例';
-
--- 插入数据：只需提供基础JSON
-INSERT INTO user_analytics (id, user_data) VALUES (
-    1, 
-    parse_json('{"name": "张三", "age": 30, "address": {"city": "北京", "zipcode": "100000"}}')
-);
-
--- 查询结果：自动包含提取的字段
-SELECT * FROM user_analytics;
--- 结果包含：id=1, user_name="张三", user_age=30, city="北京"
-```
-
-### 高级生成列应用
-
-```sql
--- 复杂JSON业务逻辑生成列
-CREATE TABLE order_analysis (
-    id INT,
-    order_json JSON,
-    
-    -- 基础字段提取
-    customer_name STRING GENERATED ALWAYS AS (
-        json_extract_string(order_json, '$.customer.name')
-    ),
-    order_amount DOUBLE GENERATED ALWAYS AS (
-        json_extract_double(order_json, '$.amount')
-    ),
-    
-    -- 业务逻辑生成列
-    amount_level STRING GENERATED ALWAYS AS (
-        if(json_extract_double(order_json, '$.amount') >= 1000, 'HIGH',
-           if(json_extract_double(order_json, '$.amount') >= 500, 'MEDIUM', 'LOW'))
-    ),
-    
-    -- 数组元素提取
-    first_product STRING GENERATED ALWAYS AS (
-        json_extract_string(order_json, '$.products[0].name')
-    ),
-    
-    -- 时间维度生成列
-    order_date STRING GENERATED ALWAYS AS (
-        json_extract_string(order_json, '$.order_time')
-    )
-) PARTITIONED BY (order_date);
-```
-
-***
-
-## 验证清单
-
-### 创建后验证（每次必做）
-
-```sql
--- 1. 创建带生成列的表
-CREATE TABLE orders_test (
-    order_id INT,
-    order_time TIMESTAMP_LTZ,
-    order_json JSON,
-    hour_col INT GENERATED ALWAYS AS (json_extract_int(order_json, '$.hour')),
-    date_str STRING GENERATED ALWAYS AS (json_extract_string(order_json, '$.date'))
-);
-
--- 2. 验证表结构
-DESCRIBE TABLE orders_test;
--- ✅ 检查：生成列是否出现在表结构中
-
--- 3. 测试数据插入
-INSERT INTO orders_test (order_id, order_time, order_json) VALUES 
-(1001, TIMESTAMP '2024-06-19 14:30:00', parse_json('{"hour": 14, "date": "2024-06-19"}'));
-
--- 4. 验证生成列值
-SELECT order_id, hour_col, date_str FROM orders_test;
--- ✅ 检查：hour_col=14, date_str='2024-06-19'
-
--- 5. 验证插入保护机制
--- INSERT INTO orders_test (order_id, order_json, hour_col) VALUES 
--- (1002, parse_json('{"hour": 15}'), 999);
--- ✅ 检查：应该报错"cannot insert or update generated column"
-```
-
-### 跨平台兼容性验证
-
-```sql
--- 6. 验证函数兼容性
-SELECT 
-    -- Hive/Spark风格（应该工作）
-    get_json_object('{"name":"test"}', '$.name') as hive_style,
-    
-    -- JSON类型函数（应该工作）
-    json_extract_string(parse_json('{"name":"test"}'), '$.name') as json_style,
-    
-    -- 聚合函数（应该工作）
-    collect_list('test') as spark_aggregate;
-
--- 7. 验证性能差异
--- 对比JSON类型 vs STRING类型的查询性能
-EXPLAIN SELECT json_extract_string(json_col, '$.field') FROM json_table;
-EXPLAIN SELECT get_json_object(string_col, '$.field') FROM string_table;
-```
-
-***
-
-## 性能优化
-
-### 1. 存储优化策略
-
-```sql
--- 高频字段优化：让系统自动识别并优化存储
-CREATE TABLE optimized_storage AS 
-SELECT parse_json(json_string) as optimized_json 
-FROM VALUES 
-    ('{"id": 1, "name": "张三", "frequent_field": "value1"}'),
-    ('{"id": 2, "name": "李四", "frequent_field": "value2"}'),
-    ('{"id": 3, "name": "王五", "frequent_field": "value3", "rare_field": "rare"}')
-as t(json_string);
-
--- 系统会自动将id, name, frequent_field列式存储
--- rare_field保持JSON存储，避免稀疏列
-```
-
-### 2. 查询优化
-
-```sql
--- ✅ 高性能：使用JSON类型 + 正确函数
-SELECT 
-    json_extract_string(json_data, '$.name'),
-    json_extract_int(json_data, '$.age')
-FROM json_table 
-WHERE json_extract_string(json_data, '$.city') = '北京';
-
--- ❌ 低性能：使用STRING类型需要全表扫描
-SELECT 
-    get_json_object(string_data, '$.name'),
-    get_json_object(string_data, '$.age')
-FROM string_table 
-WHERE get_json_object(string_data, '$.city') = '北京';
-```
-
-### 3. 通用高性能模式
-
-```sql
--- 🎯 高性能模式：JSON + 生成列 + 索引
-CREATE TABLE optimized_json (
-    id BIGINT,
-    raw_data JSON,
-    
-    -- 热点字段生成列
-    user_id STRING GENERATED ALWAYS AS (json_extract_string(raw_data, '$.user_id')),
-    timestamp_col TIMESTAMP GENERATED ALWAYS AS (
-        cast(json_extract_string(raw_data, '$.timestamp') as timestamp)
-    ),
-    event_type STRING GENERATED ALWAYS AS (json_extract_string(raw_data, '$.event_type'))
-) PARTITIONED BY (event_type);
-
--- 为生成列创建索引
-CREATE INDEX idx_user_id ON optimized_json (user_id);
-CREATE INDEX idx_timestamp ON optimized_json (timestamp_col);
-```
-
-***
-
-## 限制和注意事项
-
-### 1. JSON类型限制（通用）
-
-```sql
--- ❌ 不支持的操作
-
--- 比较操作
-SELECT * FROM json_table WHERE json_col = parse_json('{"key": "value"}');
--- 错误：operator not found, json = json
-
--- 排序操作
-SELECT * FROM json_table ORDER BY json_col;
--- 错误：require equality comparable type in ORDER BY, but got json
-
--- 分组操作
-SELECT json_col, COUNT(*) FROM json_table GROUP BY json_col;
--- 错误：不支持GROUP BY JSON类型
-
--- 作为JOIN键
-SELECT * FROM table1 t1 JOIN table2 t2 ON t1.json_col = t2.json_col;
--- 错误：不支持JSON类型作为JOIN键
-```
-
-### 2. 分区和索引限制
-
-```sql
--- ❌ 不支持作为分区键
-CREATE TABLE partitioned_table (
-    id INT,
-    data JSON
-) PARTITIONED BY (data);  -- 错误：不支持JSON作为分区键
-
--- ✅ 正确做法：使用生成列作为分区键
-CREATE TABLE partitioned_correct (
-    id INT,
-    data JSON,
-    date_part STRING GENERATED ALWAYS AS (json_extract_string(data, '$.date'))
-) PARTITIONED BY (date_part);
-```
-
-### 3. 路径语法限制
-
-```sql
--- ❌ 不支持的路径语法
--- 负数索引：'$[-1]'
--- 条件过滤：'$[?(@.price > 10)]'
--- 递归下降：'$..'
-
--- ✅ 支持的路径语法
-'$.field'              -- 字段访问
-'$.nested.field'       -- 嵌套字段
-'$[0]'                 -- 数组索引
-'$[*]'                 -- 数组所有元素
-'$["field.with.dot"]'  -- 特殊字符字段（单引号）
-```
-
-***
-
-## 常见错误
-
-### 1. 函数类型错误
-
-| 错误现象                                                                       | 原因                 | 解决方案                      |
-| -------------------------------------------------------------------------- | ------------------ | ------------------------- |
-| `function 'get_json_object' cannot be resolved, invalid type 'json'`       | 在JSON类型上使用STRING函数 | 改用`json_extract_string()` |
-| `function 'json_extract_string' cannot be resolved, invalid type 'string'` | 在STRING类型上使用JSON函数 | 改用`get_json_object()`     |
-| `operator not found, json = json`                                          | 尝试比较JSON值          | 提取为基础类型后比较                |
-
-### 2. 路径语法错误
-
-```sql
--- ❌ 错误的路径语法
-json_extract_string(data, 'name')           -- 缺少$前缀
-json_extract_string(data, '$.key.with.dot') -- 特殊字符需要括号
-
--- ✅ 正确的路径语法
-json_extract_string(data, '$.name')
-json_extract_string(data, '$["key.with.dot"]')  -- 注意使用单引号
-```
-
-### 3. 平台迁移常见错误
-
-```sql
--- ❌ Snowflake用户常犯错误
--- SELECT user_data:name FROM table;  -- 不支持:操作符
-
--- ❌ PostgreSQL用户常犯错误  
--- SELECT user_data->'name' FROM table;  -- 不支持->操作符
-
--- ❌ MySQL用户常犯错误
--- SELECT JSON_EXTRACT(json_data, '$.name') FROM table;  -- 参数类型错误
-
--- ✅ 统一的正确语法
-SELECT json_extract_string(user_data, '$.name') FROM table;  -- JSON类型
-SELECT get_json_object(user_string, '$.name') FROM table;    -- STRING类型
-```
-
-***
-
-## 迁移指导
-
-### 分阶段迁移策略
-
-#### 阶段1：评估和准备（1-2周）
-
-```sql
--- 1. 评估现有JSON使用情况
-SELECT 
-    table_name,
-    column_name,
-    data_type,
-    count(*) as usage_count
-FROM information_schema.columns 
-WHERE data_type LIKE '%json%' OR column_name LIKE '%json%'
-GROUP BY table_name, column_name, data_type;
-
--- 2. 识别高频JSON操作
--- 分析现有查询中的JSON函数使用情况
-```
-
-#### 阶段2：兼容性测试（1-2周）
-
-```sql
--- 3. 创建测试表验证兼容性
-CREATE TABLE migration_test (
-    id INT,
-    old_json_string STRING,     -- 保持原有格式
-    new_json_data JSON,         -- 新的JSON类型
-    -- 双重生成列验证
-    field_old STRING GENERATED ALWAYS AS (get_json_object(old_json_string, '$.field')),
-    field_new STRING GENERATED ALWAYS AS (json_extract_string(new_json_data, '$.field'))
-);
-
--- 4. 性能基准测试
--- 对比旧查询 vs 新查询的性能差异
-```
-
-#### 阶段3：渐进迁移（2-4周）
-
-```sql
--- 5. 新表直接使用JSON类型
-CREATE TABLE new_design_table (
-    id INT,
-    data JSON,
-    -- 关键字段生成列
-    user_id STRING GENERATED ALWAYS AS (json_extract_string(data, '$.user_id')),
-    event_type STRING GENERATED ALWAYS AS (json_extract_string(data, '$.event_type'))
-) PARTITIONED BY (event_type);
-
--- 6. 现有表添加JSON列
-ALTER TABLE existing_table ADD COLUMN 
-json_data JSON GENERATED ALWAYS AS (parse_json(json_string));
-```
-
-#### 阶段4：全面迁移（根据业务窗口）
-
-```sql
--- 7. 更新应用代码
--- 将所有JSON操作切换到新的函数和列
-
--- 8. 清理旧列（确认稳定后）
--- ALTER TABLE table_name DROP COLUMN old_json_string;
-```

-
-#### 4.3.1 高频字段访问模式优化
-
-```sql
--- 创建性能优化演示表
-CREATE TABLE IF NOT EXISTS performance_orders (
-    id INT,
-    order_data JSON,
-    created_date DATE DEFAULT CURRENT_DATE()
-);
-
--- 插入测试数据
-INSERT INTO performance_orders VALUES
-(1, parse_json('{"customer": {"id": "C001", "level": "VIP"}, "payment": {"amount": 1500.00}, "items": [{"detail": {"description": "高端电子产品"}}]}'), CURRENT_DATE()),
-(2, parse_json('{"customer": {"id": "C002", "level": "regular"}, "payment": {"amount": 2300.00}, "items": [{"detail": {"description": "家居用品"}}]}'), CURRENT_DATE()),
-(3, parse_json('{"customer": {"id": "C003", "level": "VIP"}, "payment": {"amount": 800.00}, "items": [{"detail": {"description": "日用品"}}]}'), CURRENT_DATE()),
-(4, parse_json('{"customer": {"id": "C004", "level": "diamond"}, "payment": {"amount": 3500.00}, "items": [{"detail": {"description": "奢侈品"}}]}'), CURRENT_DATE());
-
--- 高频字段访问模式优化
-WITH high_performance_query AS (
-    SELECT 
-        -- 顶层字段访问：自动列式存储优化
-        json_extract_string(order_data, "$.customer.id") as customer_id,
-        json_extract_double(order_data, "$.payment.amount") as amount,
-        json_extract_string(order_data, "$.customer.level") as level,
-        
-        -- 批量字段提取：减少重复JSON解析开销
-        order_data as full_order_data,
-        created_date
-    FROM performance_orders 
-    WHERE json_extract_string(order_data, "$.customer.id") IS NOT NULL  -- 高效顶层字段过滤
-      AND json_extract_double(order_data, "$.payment.amount") > 1000    -- 数值字段高效过滤
-)
-
--- 二次计算优化：基于预提取字段进行复杂分析
-SELECT 
-    customer_id,
-    level,
-    amount,
-    -- 复杂嵌套字段按需提取（避免全表重复解析）
-    json_extract_string(full_order_data, "$.items[0].detail.description") as product_description,
-    
-    -- 聚合优化：预分组减少计算量
-    CASE 
-        WHEN amount > 3000 THEN 'high_value'
-        WHEN amount > 1500 THEN 'medium_value'
-        ELSE 'low_value'
-    END as value_segment
-FROM high_performance_query
-ORDER BY amount DESC;
-```
-
-#### 4.3.2 JSON数据更新的替代解决方案
-
-**🚨 重要技术限制**： 经过实际验证，云器Lakehouse不支持`json_set`、`json_insert`、`json_remove`等JSON修改函数。以下是验证过的替代解决方案：
-
-**方案一：JSON完整重构（适用于简单更新**）
-
-```sql
--- 创建事务演示表
-CREATE TABLE IF NOT EXISTS transaction_demo (
-    customer_id STRING,
-    customer_data JSON,
-    updated_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP()
-);
-
--- 插入初始数据
-INSERT INTO transaction_demo VALUES
-('10001', parse_json('{"name": "张三", "level": "regular", "profile": {"upgrade_date": null}, "payment": {"vip_discount": 0}}'), CURRENT_TIMESTAMP());
-
--- 使用parse_json + CONCAT重构JSON对象进行更新
-UPDATE transaction_demo 
-SET customer_data = parse_json(CONCAT(
-    '{"name": "', json_extract_string(customer_data, "$.name"), '", ',
-    '"level": "VIP", ',
-    '"profile": {"upgrade_date": "2024-12-01"}, ',
-    '"payment": {"vip_discount": 500.0}}'
-)),
-updated_time = CURRENT_TIMESTAMP()
-WHERE customer_id = '10001'
-  AND json_extract_string(customer_data, "$.level") != 'VIP';
-
--- 验证更新结果
-SELECT 
-    customer_id,
-    json_extract_string(customer_data, "$.name") as name,
-    json_extract_string(customer_data, "$.level") as level,
-    json_extract_string(customer_data, "$.profile.upgrade_date") as upgrade_date,
-    json_extract_double(customer_data, "$.payment.vip_discount") as vip_discount
-FROM transaction_demo
-WHERE customer_id = '10001';
-```
-
-**方案二：混合存储策略（推荐用于频繁更新**）
-
-```sql
--- 频繁更新字段分离存储，稳定数据使用JSON
-CREATE TABLE IF NOT EXISTS hybrid_storage_demo (
-    id INT,
-    user_level STRING,  -- 频繁更新的字段单独存储
-    update_count INT,   -- 频繁更新的字段单独存储
-    user_profile JSON,  -- 稳定的复杂数据用JSON存储
-    last_updated TIMESTAMP DEFAULT CURRENT_TIMESTAMP()
-);
-
--- 插入混合存储数据
-INSERT INTO hybrid_storage_demo VALUES
-(1, 'VIP', 5, 
- parse_json('{"preferences": ["electronics", "books"], "address": {"city": "北京", "district": "朝阳区"}}'),
- CURRENT_TIMESTAMP());
-
--- 查询混合存储数据
-SELECT 
-    id,
-    user_level,  -- 关系型字段，更新效率高
-    update_count,  -- 关系型字段，更新效率高
-    json_extract_string(user_profile, "$.preferences[0]") as primary_preference,  -- JSON字段，查询灵活
-    json_extract_string(user_profile, "$.address.city") as city  -- JSON字段，结构化存储
-FROM hybrid_storage_demo;
-```

-FROM user_feedback_full
-WHERE json_extract_int(data, "$.score") >= 4
-ORDER BY json_extract_int(data, "$.score") DESC;
-```
-
-### 5.2 最佳实践建议
-
-#### 5.2.1 字段命名规范
-
-**推荐：使用英文字段名**
-
-```sql
--- 创建最佳实践演示表
-CREATE TABLE IF NOT EXISTS best_practice_demo (
-    id STRING,
-    data JSON
-);
-
--- 推荐的字段命名方式
-INSERT INTO best_practice_demo VALUES
-('demo001', parse_json('{"user_name": "张三", "user_city": "北京", "user_comment": "产品很好😊", "rating_score": 5}'));
-
--- 查询演示
-SELECT 
-    json_extract_string(data, "$.user_name") as name,
-    json_extract_string(data, "$.user_city") as city,
-    json_extract_string(data, "$.user_comment") as comment,
-    json_extract_int(data, "$.rating_score") as score
-FROM best_practice_demo;
-```
-
-**谨慎使用：中文字段名**
-
-```sql
--- 创建中文字段名演示表（不推荐）
-CREATE TABLE IF NOT EXISTS chinese_field_demo (
-    id STRING,
-    data JSON
-);
-
--- 中文字段名示例（可用但不推荐）
-INSERT INTO chinese_field_demo VALUES
-('demo001', parse_json('{"用户姓名": "张三", "用户城市": "北京", "用户评价": "产品很好😊"}'));
-
--- 查询中文字段名（语法正确但不推荐）
-SELECT 
-    json_extract_string(data, "$.用户姓名") as name,
-    json_extract_string(data, "$.用户城市") as city,
-    json_extract_string(data, "$.用户评价") as comment
-FROM chinese_field_demo;
-```
-
-#### 5.2.2 特殊字符处理
-
-**安全的内容格式**：
-
-```sql
--- 创建特殊字符处理演示表
-CREATE TABLE IF NOT EXISTS special_char_demo (
-    id STRING,
-    data JSON
-);
-
--- 插入包含各种特殊字符的数据
-INSERT INTO special_char_demo VALUES
-('char001', parse_json('{"message": "正常的中文内容和emoji😊", "symbols": "!@#$%^&*()_+-=[]{}|;:,.<>?/", "punctuation": "中文标点：，。；：""''（）【】、？！"}'));
-
--- 查询特殊字符数据
-SELECT 
-    json_extract_string(data, "$.message") as message,
-    json_extract_string(data, "$.symbols") as symbols,
-    json_extract_string(data, "$.punctuation") as punctuation
-FROM special_char_demo;
-```
-
-### 5.3 问题排查指南
-
-如果遇到中文或emoji显示问题：
-
-1. **检查字段命名**：优先使用英文字段名
-2. **验证JSON格式**：确保JSON格式正确，没有语法错误
-3. **使用标准函数**：统一使用json\_extract\_\*函数
-4. **避免复杂转义**：减少在JSON字符串中使用复杂的转义字符
-5. **编码设置**：确保客户端和数据库的字符编码设置正确
-
-```sql
--- 问题排查演示查询
-CREATE TABLE IF NOT EXISTS troubleshoot_demo (
-    id STRING,
-    data JSON
-);
-
--- 正确的数据插入方式
-INSERT INTO troubleshoot_demo VALUES
-('test001', parse_json('{"name": "测试用户", "message": "这是一条测试消息🔧"}'));
-
--- 验证数据是否正确存储和查询
-SELECT 
-    id,
-    json_extract_string(data, "$.name") as name,
-    json_extract_string(data, "$.message") as message,
-    LENGTH(json_extract_string(data, "$.name")) as name_length,
-    LENGTH(json_extract_string(data, "$.message")) as message_length
-FROM troubleshoot_demo;
-```

-
-## 第六章：技术限制与最佳实践
-
-### 6.1 JSON类型限制总结（验证修正版）
-
-基于完整验证发现的核心限制：
-
-#### 6.1.1 确认支持的功能
-
-**✅ 支持的JSON函数**：
-
-* `parse_json()` - JSON字符串解析
-* `json_extract_string()` - 提取字符串值
-* `json_extract_int()` - 提取整数值
-* `json_extract_double()` - 提取浮点数值
-* `json_extract()` - 通用提取函数
-
-**✅ 支持的语法**：
-
-* `CREATE TABLE IF NOT EXISTS`
-* 完整的DDL操作（CREATE/ALTER/DROP）
-* 数组访问语法 `[0]`, `[1]`
-* 嵌套对象访问 `$.path.to.field`
-* 中文和emoji内容完全支持
-
-#### 6.1.2 确认不支持的功能
-
-**❌ 不支持的JSON函数**：
-
-```sql
--- 以下函数经验证不被支持：
--- json_set() - JSON字段更新（重要限制）
-```
-
-**❌ 不支持的操作**：
-
-```sql
--- 创建限制演示表
-CREATE TABLE IF NOT EXISTS limitation_demo (
-    id INT,
-    json_data JSON
-);
-
--- 插入测试数据
-INSERT INTO limitation_demo VALUES
-(1, parse_json('{"name": "张三", "score": 85}')),
-(2, parse_json('{"name": "李四", "score": 92}')),
-(3, parse_json('{"name": "王五", "score": 78}'));
-
--- 以下操作不被支持，会导致错误：
--- JSON类型不支持直接比较
--- SELECT * FROM limitation_demo WHERE json_data = parse_json('{}');
-
--- JSON类型不支持直接排序
--- SELECT * FROM limitation_demo ORDER BY json_data;
-
--- JSON类型不支持直接GROUP BY
--- SELECT json_data, COUNT(*) FROM limitation_demo GROUP BY json_data;
-```
-
-#### 6.1.3 解决方案
-
-```sql
--- 使用json_extract函数进行比较
-SELECT * FROM limitation_demo 
-WHERE json_extract_string(json_data, "$.name") = '张三';
-
--- 提取字段后排序
-SELECT 
-    id,
-    json_extract_string(json_data, "$.name") as name,
-    json_extract_int(json_data, "$.score") as score
-FROM limitation_demo 
-ORDER BY json_extract_int(json_data, "$.score") DESC;
-
--- 提取字段后分组
-SELECT 
-    CASE 
-        WHEN json_extract_int(json_data, "$.score") >= 90 THEN 'excellent'
-        WHEN json_extract_int(json_data, "$.score") >= 80 THEN 'good'
-        ELSE 'average'
-    END as grade,
-    COUNT(*) as count
-FROM limitation_demo 
-GROUP BY CASE 
-    WHEN json_extract_int(json_data, "$.score") >= 90 THEN 'excellent'
-    WHEN json_extract_int(json_data, "$.score") >= 80 THEN 'good'
-    ELSE 'average'
-END;
-```
-
-### 6.2 JSON数据更新的替代策略
-
-#### 6.2.1 更新策略设计原则
-
-1. **读多写少原则**：JSON主要用于读取密集型场景
-2. **混合存储策略**：频繁更新字段分离存储
-3. **应用层处理**：复杂更新在应用层完成
-4. **版本化管理**：重要数据支持历史版本
-
-#### 6.2.2 具体实施方案
-
-**方案一：JSON完整重构**
-
-```sql
--- 适用于：简单JSON更新，更新频率低的场景
-UPDATE table_name 
-SET json_column = parse_json(CONCAT(
-    '{"field1": "', json_extract_string(json_column, "$.field1"), '", ',
-    '"field2": "new_value", ',
-    '"field3": ', json_extract_int(json_column, "$.field3"), '}'
-))
-WHERE conditions;
-```
-
-**方案二：混合存储策略**
-
-```sql
--- 推荐用于：有频繁更新需求的业务场景
-CREATE TABLE IF NOT EXISTS hybrid_table (
-    id INT,
-    frequently_updated_field STRING,  -- 关系型字段
-    status_field INT,                 -- 关系型字段
-    stable_json_data JSON,           -- JSON字段存储稳定数据
-    last_updated TIMESTAMP
-);
-```
-
-**方案三：版本化存储**
-
-```sql
--- 适用于：需要保留历史版本的重要数据
-CREATE TABLE IF NOT EXISTS versioned_json_data (
-    record_id STRING,
-    version_number INT,
-    json_data JSON,
-    created_time TIMESTAMP,
-    is_current BOOLEAN DEFAULT TRUE
-);
-```
-
-### 6.3 统一语法建议
-
-为了避免混合使用导致的问题，建议统一使用json\_extract函数：
-
-```sql
--- 创建语法统一演示表
-CREATE TABLE IF NOT EXISTS syntax_demo (
-    order_id STRING,
-    data JSON
-);
-
--- 插入测试数据
-INSERT INTO syntax_demo VALUES
-('ORD001', parse_json('{"customer": {"id": "C001", "name": "张三", "level": "VIP"}, "payment": {"amount": 1500.00}, "items": [{"qty": 2}]}')),
-('ORD002', parse_json('{"customer": {"id": "C002", "name": "李四", "level": "regular"}, "payment": {"amount": 800.00}, "items": [{"qty": 1}]}')),
-('ORD003', parse_json('{"customer": {"id": "C003", "name": "王五", "level": "VIP"}, "payment": {"amount": 2200.00}, "items": [{"qty": 3}]}'));
-
--- 推荐的统一语法模式
-SELECT 
-    order_id,
-    json_extract_string(data, "$.customer.id") as customer_id,
-    json_extract_string(data, "$.customer.name") as customer_name,
-    json_extract_string(data, "$.customer.level") as customer_level,
-    json_extract_double(data, "$.payment.amount") as amount,
-    json_extract_int(data, "$.items[0].qty") as quantity
-FROM syntax_demo 
-WHERE json_extract_string(data, "$.customer.level") = 'VIP'
-ORDER BY json_extract_double(data, "$.payment.amount") DESC;
-```
-
-### 6.4 类型安全处理
-
-#### 6.4.1 安全的默认值处理
-
-```sql
--- 创建类型安全演示表
-CREATE TABLE IF NOT EXISTS type_safety_demo (
-    order_id STRING,
-    order_data JSON
-);
-
--- 插入包含缺失字段的数据
-INSERT INTO type_safety_demo VALUES
-('ORD001', parse_json('{"customer": {"name": "张三", "vip_level": "gold"}, "payment": {"discount": 100}}')),
-('ORD002', parse_json('{"customer": {"name": "李四"}, "payment": {}}')),  -- 缺少vip_level和discount
-('ORD003', parse_json('{"customer": {"name": "王五", "vip_level": "silver"}, "payment": {"discount": 50}}'));
-
--- 安全的默认值处理
-SELECT 
-    order_id,
-    json_extract_string(order_data, "$.customer.name") as customer_name,
-    -- 确保类型一致的默认值处理
-    CASE WHEN json_extract_string(order_data, "$.customer.vip_level") IS NOT NULL 
-         THEN json_extract_string(order_data, "$.customer.vip_level") 
-         ELSE 'regular' 
-    END as safe_vip_level,
-    -- 数值类型的安全处理
-    CASE WHEN json_extract_double(order_data, "$.payment.discount") IS NOT NULL 
-         THEN json_extract_double(order_data, "$.payment.discount") 
-         ELSE 0.0 
-    END as safe_discount,
-    -- 使用COALESCE简化默认值处理
-    COALESCE(json_extract_string(order_data, "$.customer.vip_level"), 'regular') as vip_level_coalesce,
-    COALESCE(json_extract_double(order_data, "$.payment.discount"), 0.0) as discount_coalesce
-FROM type_safety_demo;
-```
-
-### 6.5 性能优化策略
-
-#### 6.5.1 高频字段优化
-
-```sql
--- 创建性能优化演示表
-CREATE TABLE IF NOT EXISTS perf_orders (
-    id INT,
-    order_data JSON,
-    created_date DATE DEFAULT CURRENT_DATE()
-);
-
--- 插入测试数据
-INSERT INTO perf_orders VALUES
-(1, parse_json('{"customer_id": "C001", "payment_amount": 1500.00, "items": [{"detail": {"description": "高端电子产品"}}]}'), CURRENT_DATE()),
-(2, parse_json('{"customer_id": "C002", "payment_amount": 2300.00, "items": [{"detail": {"description": "家居用品"}}]}'), CURRENT_DATE()),
-(3, parse_json('{"customer_id": "C003", "payment_amount": 800.00, "items": [{"detail": {"description": "日用品"}}]}'), CURRENT_DATE()),
-(4, parse_json('{"customer_id": "C004", "payment_amount": 3200.00, "items": [{"detail": {"description": "奢侈品"}}]}'), CURRENT_DATE());
-
--- 将常用字段放在JSON顶层，利用自动列式存储优化
-SELECT 
-    json_extract_string(order_data, "$.customer_id") as customer_id,          -- 高频字段
-    json_extract_double(order_data, "$.payment_amount") as amount,            -- 高频字段
-    json_extract_string(order_data, "$.items[0].detail.description") as desc  -- 深层字段
-FROM perf_orders 
-WHERE json_extract_string(order_data, "$.customer_id") IS NOT NULL          -- 高效过滤
-  AND json_extract_double(order_data, "$.payment_amount") > 1000;           -- 数值过滤
-```
-

-## 功能概述
-
->【**预览发布】本功能当前处于公开预览发布阶段**。
-
-本文主要介绍如何在 SQL 中创建与 Kafka 消息队列系统连接的外部表。通过定义外部表，可以方便地从 Kafka 中读取数据流，并将这些数据流作为表进行查询和分析。
-
-## 创建存储连接
-
-首先，需要创建一个存储连接，用于连接到 Kafka 服务器。目前连接需要证书的方式不支持
-
-### 语法
-
-```SQL
-CREATE STORAGE CONNECTION connection_name
-    TYPE kafka
-    BOOTSTRAP_SERVERS = ['server1:port1', 'server2:port2', ...]
-    SECURITY_PROTOCOL = 'PLAINTEXT';
-```
-
-### 参数说明
-
-* **connection\_name**: 连接的名称，用于后续引用。
-* **TYPE**: 连接类型，此处为 `kafka`。
-* **BOOTSTRAP\_SERVERS**: Kafka 集群的地址列表，格式为 `['host1:port1', 'host2:port2', ...]`。
-* **SECURITY\_PROTOCOL**: 安全协议，可以是 `PLAINTEXT` 等。
-
-### 示例
-
-```SQL
-CREATE STORAGE CONNECTION test_kafka_conn
-    TYPE kafka
-    BOOTSTRAP_SERVERS = ['47.99.48.62:9092']
-    SECURITY_PROTOCOL = 'PLAINTEXT';
-```
-
-## 创建外部表
-
-在创建了存储连接之后，可以定义外部表来读取 Kafka 中的数据。
-
-### 语法
-
-```SQL
-CREATE EXTERNAL TABLE IF NOT EXISTS external_table_name (
- `topic` string,
- `partition` int,
- `offset` bigint,
- `timestamp` timestamp_ltz,
- `timestamp_type` string,
-`headers` map<string, string>,
- `key` binary, `value` binary)
-USING kafka
-CONNECTION connection_name
-OPTIONS (
-    'group_id' = 'consumer_group',
-    'topics' = 'topic_name',
-    'starting_offset' = 'earliest' -- 可选，默认值 earliest
-) ;

-> 虚拟计算集群是Lakehouse提供数据处理、分析的计算资源对象，提供执行SQL作业所需的CPU、内存、本地临时存储等资源。集群具备快速创建/销毁、扩容/缩容、暂停/恢复等特点，按照资源规格大小以及使用时长计费，暂停或删除后不产生费用。Lakehouse提供两种类型的集群：通用型(适合ETL数据加工)和分析型(适合查询分析)。
-
-## 基础操作
-
-### 1. 运行您的第一个SQL查询
-
-在这个练习中，您将执行简单的SQL查询、创建表并进行基本分析。预计用时：2-3分钟。
-
-1. 登录 Lakehouse Studio
-
-2. 创建一个新的 SQL 工作表，命名为“01_我的第一个SQL”
-
-3. 执行以下SQL命令：
-
-   ```sql
-   -- 使用已创建的虚拟集群和Schema
-   USE VCLUSTER MY_FIRST_VC;
-   USE SCHEMA happy_path;
-
-   -- 简单查询
-   SELECT 1 as id, '你好，Lakehouse！' as greeting;
-   ```
-
-4. 创建一个简单的表并插入数据：
-
-   ```sql
-   -- 创建一个简单的产品表
-   CREATE TABLE IF NOT EXISTS happy_path.my_first_table (
-     product_id INT,
-     product_name STRING,
-     price DECIMAL(10,2),
-     category STRING
-   );
-
-   -- 插入一些示例数据
-   INSERT INTO happy_path.my_first_table VALUES
-     (101, '高清智能电视', 3999.99, '电子产品'),
-     (102, '无线蓝牙耳机', 799.00, '电子产品'),
-     (103, '智能手表', 1299.50, '可穿戴设备'),
-     (104, '便携式充电宝', 159.90, '配件'),
-     (105, '机械键盘', 349.00, '电脑配件');
-     
-   -- 查询刚插入的数据
-   SELECT * FROM happy_path.my_first_table;
-   ```
-
-5. 运行一个聚合查询：
-
-   ```sql
-   -- 按类别统计产品数量和平均价格
-   SELECT 
-     category,
-     COUNT(*) as product_count,
-     AVG(price) as avg_price,
-     MIN(price) as min_price,
-     MAX(price) as max_price
-   FROM happy_path.my_first_table
-   GROUP BY category
-   ORDER BY avg_price DESC;
-   ```
-
-**提示**：您可以看到，无需任何复杂配置，就可以立即执行 SQL 查询、创建表、插入数据和进行分析，这体现了 Lakehouse 简单易用的特性。
-
-### 2. 创建第二个计算集群
-
-接下来，我们来创建一个不同类型的计算集群，了解如何根据不同场景选择合适的计算资源。预计用时：3-6分钟。
-
-1. 创建一个新的 SQL 工作表，命名为“02_创建分析型计算集群”
-
-2. 检查当前环境：
-
-   ```sql
-   -- 确认当前使用的集群和Schema
-   SELECT CURRENT_VCLUSTER();
-   USE SCHEMA happy_path;
-   ```
-
-3. 创建分析型虚拟计算集群：
-
-   ```sql
-   -- 创建分析型虚拟计算集群
-   -- 分析型集群优化了查询性能，适合低延时、高并发的分析场景
-   CREATE VCLUSTER IF NOT EXISTS MY_SECOND_VC 
-   VCLUSTER_SIZE = 1 
-   VCLUSTER_TYPE = ANALYTICS 
-   AUTO_SUSPEND_IN_SECOND = 60 
-   AUTO_RESUME = TRUE 
-   COMMENT '我的第二个虚拟计算集群(分析型)';
-   ```
-
-4. 切换到新创建的集群并测试：
-
-   ```sql
-   -- 使用分析型集群
-   USE VCLUSTER MY_SECOND_VC;
-   USE SCHEMA happy_path;
-
-   -- 创建一个简单的测试表
-   CREATE TABLE IF NOT EXISTS happy_path.simple_test (
-     id INT,
-     name STRING,
-     value DOUBLE
-   );
-
-   -- 插入几行示例数据
-   INSERT INTO happy_path.simple_test VALUES
-     (1, '产品A', 99.5),
-     (2, '产品B', 150.75),
-     (3, '产品C', 25.99);
-
-   -- 查询刚插入的数据
-   SELECT * FROM happy_path.simple_test;
-   ```
-
-5. 查看集群信息：
-
-   ```sql
-   -- 查看当前使用的集群
-   SELECT CURRENT_VCLUSTER();
-
-   -- 查看所有集群
-   SHOW VCLUSTERS;
-   ```
-
-> **💡 提示：集群类型选择**
-> 通用型集群(GENERAL)支持纵向伸缩，满足ETL Pipeline类型的任务需求；分析型集群(ANALYTICS)支持集群内多副本(Replica)的横向伸缩，满足面向并发查询的弹性能力。建议使用通用型集群进行ETL数据加工，使用分析型集群进行查询分析或支持数据产品应用。
-
-## 核心架构体验
-
-### 3. 存算分离架构体验
-
-存算分离是 Lakehouse 的核心架构特性，让您可以灵活调整计算资源而不影响数据存储。预计用时：5-8分钟。
-
-1. 创建一个新的 SQL 工作表，命名为“03_存算分离体验”
-
-2. 准备环境：
-
-   ```sql
-   -- 使用第一个集群(通用型)
-   USE VCLUSTER MY_FIRST_VC;
-   USE SCHEMA happy_path;
-   ```
-
-3. 创建测试数据集：
-
-   ```sql
-   -- 创建一个用于测试的数据集
-   CREATE TABLE IF NOT EXISTS happy_path.demo_dataset (
-     id INT,
-     value DOUBLE,
-     text_data STRING,
-     created_at TIMESTAMP
-   );
-
-   -- 插入一些示例数据
-   INSERT INTO happy_path.demo_dataset VALUES
-     (1, 123.45, 'Text-1', CURRENT_TIMESTAMP()),
-     (2, 678.90, 'Text-2', CURRENT_TIMESTAMP()),
-     (3, 246.80, 'Text-3', CURRENT_TIMESTAMP()),
-     (4, 135.79, 'Text-4', CURRENT_TIMESTAMP()),
-     (5, 975.31, 'Text-5', CURRENT_TIMESTAMP());
-   ```
-
-4. 在第一个集群上查询数据：
-
-   ```sql
-   -- 确认当前使用的集群
-   SELECT CURRENT_VCLUSTER();
-
-   -- 查询数据集
-   SELECT * FROM happy_path.demo_dataset ORDER BY id;
-   ```
-
-5. 切换到第二个集群查询相同数据：
-
-   ```sql
-   -- 切换到第二个集群(分析型)
-   USE VCLUSTER MY_SECOND_VC;
-   USE SCHEMA happy_path;
-
-   -- 查询相同的数据集
-   SELECT * FROM happy_path.demo_dataset ORDER BY id;
-   ```
-
-6. 在第二个集群上添加新数据：
-
-   ```sql
-   -- 在第二个集群上添加新数据
-   INSERT INTO happy_path.demo_dataset VALUES
-     (6, 432.10, 'Text-6', CURRENT_TIMESTAMP()),
-     (7, 789.65, 'Text-7', CURRENT_TIMESTAMP());
-     
-   -- 查询更新后的数据集
-   SELECT * FROM happy_path.demo_dataset ORDER BY id;
-   ```
-
-7. 切换回第一个集群，查看数据变化：
-
-   ```sql
-   -- 切换回第一个集群
-   USE VCLUSTER MY_FIRST_VC;
-   USE SCHEMA happy_path;
-
-   -- 查询数据，验证在另一个集群上添加的数据是否可见
-   SELECT * FROM happy_path.demo_dataset ORDER BY id;
-   ```
-
-> **💡 提示：存算分离架构**
-> Lakehouse采用Single Engine All Data架构，将计算和存储分开，使系统能够更快地处理查询任务。这种架构使计算资源可以根据需求弹性调整，而数据存储在云对象存储中实现"无限扩展"。当不使用集群时，它会自动暂停以节省资源，需要时会自动恢复，有效降低总体拥有成本(TCO)。
-
-### 4. 湖仓一体架构体验
-
-湖仓一体架构允许您用统一的 SQL 直接查询多种格式的文件，无需复杂的 ETL 转换。预计用时：7-10分钟。
-
-1. 创建一个新的 SQL 工作表，命名为“04_湖仓一体体验”
-
-2. 准备环境：
-
-   ```sql
-   -- 使用第一个集群(通用型)，更适合大批量数据导入导出处理
-   USE VCLUSTER MY_FIRST_VC;
-   USE SCHEMA happy_path;
-   ```
-
-3. 创建并准备数据：
-
-   ```sql

-   FROM happy_path.sales_for_lake
-   FILE_FORMAT = (TYPE = CSV HEADER = TRUE)
-   OVERWRITE = TRUE;
-
-   -- 查看所有导出的文件
-   LIST USER VOLUME SUBDIRECTORY 'lake_demo';
-   ```
-
-6. 使用分析型集群直接查询不同格式文件：
-
-   ```sql
-   -- 切换到分析型集群进行交互式查询
-   USE VCLUSTER MY_SECOND_VC;
-   USE SCHEMA happy_path;
-
-   -- 注意：根据实际导出文件名调整FILES参数
-
-   -- 1. 查询CSV格式文件
-   SELECT * FROM USER VOLUME
-   USING csv
-   OPTIONS('header'='true')
-   FILES('lake_demo/products_csv/part00001.csv')
-   LIMIT 5;
-
-   -- 2. 查询JSON格式文件
-   SELECT * FROM USER VOLUME
-   USING json
-   FILES('lake_demo/products_json/part00001.json')
-   LIMIT 5;
-
-   -- 3. 查询Parquet格式文件
-   SELECT * FROM USER VOLUME
-   USING parquet
-   FILES('lake_demo/products_parquet/part00001.parquet')
-   LIMIT 5;
-   ```
-
-7. 联合查询不同格式的文件：
-
-   ```sql
-   -- 联合查询Parquet格式的产品数据和CSV格式的销售数据
-   SELECT
-      p.product_id,
-      p.product_name,
-      p.category,
-      p.price,
-      s.quantity as quantity_sold,
-      s.total_amount as sales_amount
-   FROM (
-     SELECT * FROM USER VOLUME USING parquet FILES('lake_demo/products_parquet/part00001.parquet')
-   ) p
-   JOIN (
-     SELECT * FROM USER VOLUME USING csv OPTIONS('header'='true') FILES('lake_demo/sales_csv/part00001.csv')
-   ) s ON p.product_id = s.product_id
-   ORDER BY sales_amount DESC;
-   ```
-
-> **注意**：执行上述语句时，请确保文件路径和文件名与实际导出的文件一致。如果文件名不同，请根据`LIST USER VOLUME`命令的结果调整FILES参数中的文件名。
-
-> **💡 提示：湖仓一体架构**
-> Lakehouse作为湖仓一体化的数据平台，可以无缝连接云上对象存储，并利用一体化的数据处理引擎高效处理数据湖中的半结构化和非结构化数据。通过Volume对象，用户可以轻松将图片、文本等非结构化数据导入数据平台，并进行分析处理。湖仓一体架构将结构化和非结构化数据整合于统一的Catalog-Schema视图，解决统一的湖仓元数据管理和权限管理问题。
-

-   SELECT order_id, customer_id, product_id, order_amount, order_time, status, 'historical' as data_source
-   FROM happy_path.historical_orders
-   UNION ALL
-   SELECT order_id, customer_id, product_id, order_amount, order_time, status, 'realtime' as data_source
-   FROM happy_path.realtime_orders;
-   ```
-
-5. 查询统一视图：
-
-   ```sql
-   -- 查询所有订单
-   SELECT * FROM happy_path.all_orders ORDER BY order_time DESC;
-
-   -- 查看订单统计
-   SELECT 
-     data_source,
-     COUNT(*) as order_count,
-     SUM(order_amount) as total_amount
-   FROM happy_path.all_orders
-   GROUP BY data_source;
-   ```
-
-6. 模拟实时数据写入：
-
-   ```sql
-   -- 插入新的实时订单
-   INSERT INTO happy_path.realtime_orders VALUES
-     ('ORD004', 'CUST003', 'PROD-B', 59.95, CURRENT_TIMESTAMP(), 'PENDING');
-   ```
-
-7. 再次查询统计结果，查看变化：
-
-   ```sql

-   SELECT 
-     product_id,
-     product_name,
-     category,
-     description,
-     price
-   FROM happy_path.product_search_demo
-   WHERE match_phrase(description, '高性能', MAP('analyzer', 'chinese'))
-   ORDER BY price DESC;
-   ```
-
-8. 向量和倒排索引融合检索：
-
-   ```sql
-   -- 融合查询：找到类似于参考向量且描述中包含"游戏"的产品
-   SELECT 
-     product_id,
-     product_name,
-     category,
-     description,
-     price,
-     l2_distance(vec, vector(0.2, 0.3, 0.4, 0.5, 0.6, 0.2, 0.3, 0.4, 0.5, 0.6, 0.2, 0.3, 0.4, 0.5, 0.6, 0.2)) AS distance
-   FROM happy_path.product_search_demo
-   WHERE 
-     match_phrase(description, '游戏', MAP('analyzer', 'chinese')) AND
-     l2_distance(vec, vector(0.2, 0.3, 0.4, 0.5, 0.6, 0.2, 0.3, 0.4, 0.5, 0.6, 0.2, 0.3, 0.4, 0.5, 0.6, 0.2)) < 10
-   ORDER BY distance
-   LIMIT 5;
-   ```
-
-9. 复杂的混合查询场景：
-
-   ```sql
-   -- 查找价格在500-10000元之间，描述中包含"高性能"或"专业"，并且向量相似度高的产品
-   SELECT 
-     product_id,
-     product_name,
-     category,
-     description,
-     price,
-     l2_distance(vec, vector(0.2, 0.3, 0.4, 0.5, 0.6, 0.2, 0.3, 0.4, 0.5, 0.6, 0.2, 0.3, 0.4, 0.5, 0.6, 0.2)) AS distance
-   FROM happy_path.product_search_demo
-   WHERE 
-     price BETWEEN 500 AND 10000 AND
-     (match_phrase(description, '高性能', MAP('analyzer', 'chinese')) OR 
-      match_phrase(description, '专业', MAP('analyzer', 'chinese'))) AND
-     l2_distance(vec, vector(0.2, 0.3, 0.4, 0.5, 0.6, 0.2, 0.3, 0.4, 0.5, 0.6, 0.2, 0.3, 0.4, 0.5, 0.6, 0.2)) < 10
-   ORDER BY distance
-   LIMIT 5;
-   ```
-
->sql
-   -- 使用第一个集群(通用型)，更适合批量数据处理和转换
-   USE VCLUSTER MY_FIRST_VC;
-   USE SCHEMA happy_path;
-   ```
-
-3. 创建并填充销售数据表：
-
-   ```sql
-   -- 创建并填充销售数据表
-   CREATE TABLE IF NOT EXISTS happy_path.sales_data (
-     sale_id INT,
-     customer_id STRING,
-     product_id STRING,
-     category STRING,
-     amount DECIMAL(10,2),
-     date_time TIMESTAMP
-   );
-
-   -- 插入模拟销售数据
-   INSERT INTO happy_path.sales_data VALUES
-     (1, 'CUST-10', 'PROD-23', '电子产品', 399.99, DATEADD(DAY, -29, CURRENT_TIMESTAMP())),
-     (2, 'CUST-15', 'PROD-41', '服装', 129.50, DATEADD(DAY, -27, CURRENT_TIMESTAMP())),

-   GROUP BY category, year, month;
-
-   -- 查询业务洞察
-   SELECT * FROM happy_path.business_insights
-   ORDER BY year DESC, month DESC, monthly_sales DESC;
-   ```
-
-9. 销售排名与占比分析：
-
-   ```sql
-   -- 分析各品类的销售排名与占比
-   SELECT 
-     category,
-     SUM(total_sales) as category_sales,
-     RANK() OVER (ORDER BY SUM(total_sales) DESC) as sales_rank,
-     SUM(total_sales) / SUM(SUM(total_sales)) OVER () * 100 as sales_percentage,
-     SUM(customer_count) as category_customers,
-     RANK() OVER (ORDER BY SUM(customer_count) DESC) as customer_rank,
-     SUM(customer_count) / SUM(SUM(customer_count)) OVER () * 100 as customer_percentage
-   FROM happy_path.sales_summary
-   GROUP BY category
-   ORDER BY category_sales DESC;
-   ```
-
-> **💡 提示：集群负载优化**
-> 在数据处理流程中，可以根据不同的操作类型选择合适的集群类型：通用型集群更适合批量数据处理和转换任务，如 ETL 操作、数据清洗和聚合计算；分析型集群则更适合交互式查询和分析，特别是需要快速响应的仪表盘和报表场景。通过合理分配计算负载，可以优化资源使用并提高整体性能。
-

-
-## 1. 简介
-
-### 1.1 什么是Table Stream
-
-Table Stream 是云器 Lakehouse 架构中的核心功能，提供变更数据捕获 (CDC) 能力，用于记录表中数据的插入、更新和删除操作。它创建了一个“变更表”，使用户能够查询和消费两个事务时间点之间的行级变更记录。
-
-### 1.2 核心功能
-
-* **变更捕获**：记录表级 DML 操作 (INSERT、UPDATE、DELETE)
-* **元数据记录**：提供每次变更的版本、时间戳等元数据
-* **增量处理**：支持增量读取和处理数据变更
-* **消费机制**：支持通过 DML 操作消费变更数据并移动 offset
-
-### 1.3 适用场景
-
-* 数据同步和复制
-* 实时数据集成
-* 增量 ETL/ELT 流程
-* 审计和数据治理
-* 事件驱动架构
-
-## 2. 准备工作
-
-### 2.1 表配置要求
-
-在使用Table Stream之前，必须确保源表已正确配置：
-
-```sql
--- 创建源表示例
-CREATE TABLE source_table (
-    id INT,
-    name STRING,
-    value DOUBLE,
-    updated_at TIMESTAMP
-);
-```
-
-### 2.2 开启变更跟踪（必需步骤）
-
-**重要**：必须在源表上开启变更跟踪才能创建 Table Stream：
-
-```sql
--- 开启变更跟踪
-ALTER TABLE source_table SET PROPERTIES ('change_tracking' = 'true');
-```
-
-这一步是**强制性**的，如果不执行，Table Stream 可能会创建成功但无法正确捕获变更。
-
-### 2.3 准备目标表
-
-如果计划将Stream数据写入目标表，提前创建具有兼容结构的目标表：
-
-```sql
--- 创建目标表
-CREATE TABLE target_table (
-    id INT,
-    name STRING,
-    value DOUBLE,
-    updated_at TIMESTAMP
-);
-```
-
-## 3. 创建和配置
-
-### 3.1 基本语法
-
-创建Table Stream的基本语法：
-
-```sql
-CREATE TABLE STREAM stream_name 
-ON TABLE source_table
-[COMMENT 'stream description']
-WITH PROPERTIES (
-    'TABLE_STREAM_MODE' = 'STANDARD|APPEND_ONLY',
-    ['SHOW_INITIAL_ROWS' = 'TRUE|FALSE']
-);
-```
-
-### 3.2 重要参数
-
-#### 3.2.1 TABLE\_STREAM\_MODE
-
-* **STANDARD**：捕获所有DML操作(INSERT、UPDATE、DELETE)，反映表的当前状态
-* **APPEND\_ONLY**：只捕获INSERT操作，即使行被更新或删除也保留原始INSERT记录
-
-#### 3.2.2 SHOW\_INITIAL\_ROWS
-
-* **TRUE**：首次消费时返回创建Stream时表中的所有现有行
-* **FALSE**（默认）：首次消费只返回创建Stream后的新变更
-
-### 3.3 时间点设置
-
-可以指定Stream开始捕获变更的时间点：
-
-```sql
-CREATE TABLE STREAM stream_name 
-ON TABLE source_table
-TIMESTAMP AS OF current_timestamp()
-WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
-```
-
-**最佳实践**：使用 `current_timestamp()` 或具体的时间戳字符串，避免使用复杂的时间表达式。
-
-### 3.4 注释添加
-
-为Stream添加描述性注释：
-
-```sql
-CREATE TABLE STREAM stream_name 
-ON TABLE source_table
-COMMENT '捕获source_table的数据变更'
-WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
-```
-
-**注意**：使用正确的语法 `COMMENT '注释内容'`，而非 `COMMENT = '注释内容'`。
-
-## 4. 使用不同模式
-
-### 4.1 STANDARD模式
-
-**推荐用途**：需要表的完整当前状态，包括更新和删除操作。
-
-```sql
-CREATE TABLE STREAM standard_stream 
-ON TABLE source_table
-WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
-```
-
-特点：
-
-* 准确反映表的当前状态
-* 更新会显示最新值
-* 已删除的行不会出现在结果中
-
-### 4.2 APPEND\_ONLY模式
-
-**推荐用途**：需要保留所有插入记录，包括后续被更新或删除的记录。
-
-```sql
-CREATE TABLE STREAM append_stream 
-ON TABLE source_table
-WITH PROPERTIES ('TABLE_STREAM_MODE' = 'APPEND_ONLY');
-```
-
-特点：
-
-* 记录所有INSERT操作
-* 不反映UPDATE和DELETE操作
-* 即使行被删除，原始INSERT记录仍会保留
-
-### 4.3 模式选择指南
-
-| 需求             | 推荐模式         |
-| -------------- | ------------ |
-| 数据同步（保持目标与源一致） | STANDARD     |
-| 审计所有插入记录       | APPEND\_ONLY |
-| 增量ETL流程        | STANDARD     |
-| 历史记录保留         | APPEND\_ONLY |
-
-## 5. 消费和处理数据
-
-### 5.1 查询Stream数据
-
-```sql
--- 查询Stream中的变更数据
-SELECT * FROM my_stream;
-```
-
-**重要**：仅使用 SELECT 查询不会移动 Stream 的 offset。
-
-### 5.2 消费和移动Offset
-
-要移动 Stream 的 offset（消费数据），必须使用 DML 操作：
-
-```sql
--- 将Stream数据插入目标表（会移动offset）
-INSERT INTO target_table
-SELECT id, name, value, updated_at 
-FROM my_stream;
-```
-
-### 5.3 消费模式
-
-#### 5.3.1 全量消费
-
-```sql
--- 消费Stream中的所有变更数据
-INSERT INTO target_table
-SELECT id, name, value, updated_at 
-FROM my_stream;
-```
-
-#### 5.3.2 条件消费
-
-```sql
--- 仅消费特定条件的变更数据
-INSERT INTO target_table
-SELECT id, name, value, updated_at 
-FROM my_stream
-WHERE value > 100;
-```
-
-**注意**：即使使用 WHERE 条件，所有 Stream 数据的 offset 仍会移动。
-
-### 5.4 验证消费状态
-
-通过再次查询Stream，验证数据是否被消费：
-
-```sql
--- 验证消费后的Stream状态
-SELECT COUNT(*) FROM my_stream;
-```
-
-如果消费成功，COUNT应该为0或只包含新的变更数据。
-
-## 6. 元数据字段使用
-
-### 6.1 可用元数据字段
-
-Table Stream返回的结果包含以下元数据字段：
-
-* `__change_type`：变更类型
-* `__commit_version`：提交版本
-* `__commit_timestamp`：提交时间戳
-
-### 6.2 变更类型判断
-
-**注意**：根据我们的测试，`__change_type` 字段的实际行为可能与文档描述不一致。所有记录都标记为“INSERT”，即使是更新或删除操作。
-
-因此，建议通过以下方式判断变更类型：
-
-1. **INSERT操作**：新记录出现在Stream中
-2. **UPDATE操作**：同一ID记录的`__commit_version`字段值增加
-3. **DELETE操作**：记录不再出现在 STANDARD 模式的结果中
-
-### 6.3 使用元数据实现增量处理
-
-```sql
--- 基于提交版本筛选
-SELECT * FROM my_stream
-WHERE __commit_version > last_processed_version;
-
--- 基于提交时间筛选
-SELECT * FROM my_stream
-WHERE __commit_timestamp > TIMESTAMP '2025-05-01 00:00:00';
-```
-
-### 6.4 元数据字段最佳实践
-
-* 不要依赖 `__change_type` 字段区分操作类型
-* 使用 `__commit_version` 和 `__commit_timestamp` 跟踪变更
-* 关注数据的最终状态而非变更过程
-* 保存消费的最大版本号，用于故障恢复
-
-## 7. 实际应用场景
-
-### 7.1 实时数据同步
-
-```sql
--- 定期执行，将变更同步到目标表
-INSERT INTO target_table
-SELECT id, name, value, updated_at 
-FROM source_stream;
-```
-
-可结合定时任务或触发器实现自动同步。
-
-### 7.2 增量ETL流程
-
-```sql
--- 增量提取、转换并加载数据
-INSERT INTO dwh_fact_table (dimension_id, metric_value, load_date)
-SELECT 
-    dim.dimension_id,
-    stream.value,
-    current_date()
-FROM source_stream stream
-JOIN dimension_table dim ON stream.id = dim.source_id;
-```
-
-### 7.3 事件驱动处理
-
-```sql
--- 检测特定事件并触发处理
-CREATE OR REPLACE PROCEDURE process_high_value_changes() AS
-BEGIN
-    -- 检查是否有高价值变更
-    DECLARE high_value_changes CURSOR FOR 
-        SELECT * FROM value_stream WHERE value > 1000;
-    
-    -- 处理这些变更
-    FOR change IN high_value_changes DO
-        -- 执行处理逻辑
-        INSERT INTO high_value_alerts VALUES (change.id, change.value, current_timestamp());
-    END FOR;
-    
-    -- 消费所有变更
-    INSERT INTO processed_changes
-    SELECT * FROM value_stream;
-END;
-```
-
-### 7.4 审计跟踪
-
-```sql
--- 捕获所有变更用于审计
-CREATE TABLE STREAM audit_stream 
-ON TABLE sensitive_data
-WITH PROPERTIES (
-    'TABLE_STREAM_MODE' = 'APPEND_ONLY',
-    'SHOW_INITIAL_ROWS' = 'TRUE'
-);
-
--- 定期归档到审计表
-INSERT INTO audit_history
-SELECT 
-    *,
-    __commit_timestamp AS audit_timestamp,
-    __commit_version AS change_version
-FROM audit_stream;
-```
-
-## 8. 性能优化
-
-### 8.1 减少数据体积
-
-* 只选择必要的列而非 `SELECT *`
-* 在源表上设置适当的保留期
-* 定期消费Stream数据以避免累积
-
-### 8.2 批量处理
-
-```sql
--- 批量消费多个Stream并合并处理
-INSERT INTO consolidated_target
-SELECT 'customers' AS source, id, name, NULL AS product_id, NULL AS order_id, __commit_timestamp
-FROM customer_stream
-UNION ALL
-SELECT 'products' AS source, id, name, product_id, NULL AS order_id, __commit_timestamp
-FROM product_stream
-UNION ALL
-SELECT 'orders' AS source, id, NULL AS name, NULL AS product_id, order_id, __commit_timestamp
-FROM order_stream;
-```
-
-### 8.3 并行处理
-
-将大型Stream拆分为多个较小的部分并行处理：
-
-```sql
--- 分区1处理
-INSERT INTO target_partition_1
-SELECT * FROM source_stream WHERE MOD(id, 4) = 0;
-
--- 分区2处理
-INSERT INTO target_partition_2
-SELECT * FROM source_stream WHERE MOD(id, 4) = 1;
-
--- 以此类推...
-```
-
-### 8.4 频率优化
-
-* 高变更率表：更频繁地消费Stream
-* 低变更率表：降低消费频率
-* 关键表：实时或近实时消费
-* 非关键表：批量定期消费
-
-## 9. 常见问题和解决方案
-
-### 9.1 Stream不捕获变更
-
-**问题**：创建 Stream 后未能捕获表变更。
-
-**解决方案**：
-
-1. 确认已开启变更跟踪：`ALTER TABLE table_name SET PROPERTIES ('change_tracking' = 'true')`
-2. 验证是否有足够权限
-3. 确认 DML 操作在 Stream 创建后执行
-
-### 9.2 无法区分变更类型
-
-**问题**：所有变更都标记为INSERT，无法区分更新和删除。
-
-**解决方案**：
-
-1. 使用 `__commit_version` 变化判断更新
-2. 记录之前的状态并与当前比较
-3. 对于STANDARD模式，通过记录是否存在来判断删除
-
-### 9.3 重复消费数据
-
-**问题**：重复运行消费逻辑导致目标表出现重复数据。
-
-**解决方案**：
-
-1. 使用MERGE语句替代INSERT
-2. 实现幂等性处理
-3. 记录最后消费的版本和时间戳
-
-```sql
--- 幂等消费示例
-MERGE INTO target_table t
-USING my_stream s
-ON t.id = s.id
-WHEN MATCHED THEN
-    UPDATE SET 
-        t.name = s.name,
-        t.value = s.value,
-        t.updated_at = s.updated_at
-WHEN NOT MATCHED THEN
-    INSERT (id, name, value, updated_at)
-    VALUES (s.id, s.name, s.value, s.updated_at);
-```
-
-### 9.4 消费后未移动Offset
-
-**问题**：消费后再次查询仍返回相同数据。
-
-**解决方案**：
-
-1. 确保使用 DML 操作消费数据（INSERT、UPDATE、MERGE）
-2. 不要仅使用 SELECT 查询，这不会移动 offset
-3. 检查 DML 操作是否成功提交
-
-## 10. 最佳实践总结
-
-### 10.1 设计原则
-
-1. **始终开启变更跟踪**：在创建Stream前开启表的变更跟踪
-2. **选择合适的模式**：根据需求选择STANDARD或APPEND\_ONLY模式
-3. **定期消费**：不要让Stream累积过多数据
-4. **关注最终状态**：重点关注数据的最终状态而非变更过程
-5. **不依赖变更类型**：不要依赖 `__change_type` 字段区分操作类型
-
-### 10.2 使用清单
-
-* [ ] 在源表上开启change\_tracking
-* [ ] 选择合适的Stream模式
-* [ ] 考虑是否需要SHOW\_INITIAL\_ROWS
-* [ ] 使用DML操作消费数据
-* [ ] 实现幂等性消费机制
-* [ ] 监控Stream大小和性能
-* [ ] 记录消费的版本和时间戳
-* [ ] 实现错误处理和重试逻辑
-
-### 10.3 成功实现的关键
-
-* **理解机制**：掌握Stream的工作原理和限制
-* **适当测试**：在生产环境部署前充分测试
-* **定期维护**：监控和优化Stream性能
-* **记录状态**：跟踪消费状态，确保数据一致性
-* **容错设计**：考虑故障恢复和边缘情况
-
-遵循这些最佳实践，您将能够充分利用云器Lakehouse Table Stream功能，构建高效可靠的数据变更捕获和处理流程。

-# 云器Lakehouse费用异常告警配置指南
-
-## 概述
-
-本指南帮助您快速配置费用异常监控系统，实现费用突增时的自动告警，保障您的成本安全。
-
-## 前置条件
-
-* 拥有 instance_admin 角色权限，用于查询 sys.information_schema.instance_usage 视图中的费用数据。
-* 拥有 instance_sre 角色权限，用于使用“数据质量”和“监控告警”功能。
-* 具备某一工作空间内计算集群的使用权限（用于执行质量规则查询 SQL）和某一表或视图的元数据查询（read metadata）权限（用于配置质量规则）。
-
-## 使用数据
-
-sys.information_schema.instance_usage 视图的字段和内容介绍可见于文末附录。
-
-## 配置步骤
-
-### 步骤1：创建数据质量规则
-
-1\. 进入**数据质量管理**模块
-
-2\. 点击**创建质量规则**
-
-:-: ![](.topwrite/assets/image_1760009305873.png =804)
-
-^
-
-3\. 填写基本信息：
-
-:-:
-![](.topwrite/assets/image_1760009346751.png =793)
-
-在本案例中主要关注以下三个选项：
-1) 校验方式：选择“自定义 SQL”；
-2) 根据本文建议的规则，直接将 SQL 粘贴到文本框中；
-3) 在“期待结果”中，根据所选择的规则配置对应的预期条件和值。
-
-其他字段配置可详见数据质量的完整配置文档：[数据质量](https://www.yunqi.tech/documents/DataQuality)
-
-### 步骤2：配置监控告警
-
-1\. 进入**监控告警**模块，点击“**新建规则**”
-
-:-: ![](.topwrite/assets/image_1760009359793.png =776)
-
-2\. 配置告警规则
-
-在本案例中主要关注以下3个选项：
-
-1) 监控事项：选择 **数据质量监控失败** 告警，并 **添加过滤条件**，以有效过滤掉其他质量规则，避免因其他质量规则校验失败而产生的干扰。
-
-2) 通知策略：根据实际需要选择所需的通知策略，也可单独新建一条通知策略。通知策略的相关配置可参考文档：[监控告警系统](https://www.yunqi.tech/documents/monitoring_and_alerting)。
-
-3) 通知人员：选择关注费用的相关人员。可以通过在账户中心新建用户，将需要通知的用户添加到此列表中。
-
-:-: ![](.topwrite/assets/image_1760009490281.png =640)
-
-完成上述两步配置，即完成了从监控到告警的完整流程。当质量规则监控到异常时，您将通过对应渠道收到告警信息。
-
-下面具体说明在数据质量规则中，可供选择的监控规则。
-
-## 监控方案
-
-### 方案一：固定阈值监控（简单快速）
-
-**适用场景**：费用相对稳定，有明确的预算上限。
-
-**监控SQL**：
-
-```SQL
--- 查询昨日总费用
-SELECT
-  ROUND(SUM(COALESCE(total_after_discount, amount * discount_rate)), 2) AS total_amount
-FROM sys.information_schema.instance_usage
-WHERE CAST(SUBSTR(measurement_start, 1, 10) AS DATE) = current_date() - INTERVAL 1 DAY
-```
-
-**告警配置**：
-* 预期结果 ≤ 50（根据实际调整阈值）
-* 超过阈值则触发告警
-
-**阈值参考查询**：
-
-```SQL
--- 查询过去90天的费用参考值
-WITH day_sum AS (
-  SELECT
-    CAST(SUBSTR(measurement_start, 1, 10) AS DATE) AS bill_date,
-    SUM(COALESCE(total_after_discount, amount * discount_rate)) AS day_amount
-  FROM sys.information_schema.instance_usage
-  WHERE CAST(SUBSTR(measurement_start, 1, 10) AS DATE) BETWEEN 
-    date_sub(current_date(), 90) AND current_date() - INTERVAL 1 DAY
-  GROUP BY 1
-)
-SELECT
-  ROUND(MAX(day_amount), 2) AS max_daily,      -- 历史最高
-  ROUND(AVG(day_amount), 2) AS avg_daily,      -- 平均值
-  ROUND(percentile_approx(day_amount, 0.95), 2) AS p95_daily  -- 95分位
-FROM day_sum
-```
-
-### 方案二：动态基线监控（关注异常波动）
-
-**适用场景**：费用存在稳定的上升或下降趋势，需要关注费用波动而非绝对值。
-
-**监控SQL**：
-
-```SQL
--- 昨日费用与历史中位数对比
-WITH daily_costs AS (
-  SELECT
-    to_date(substr(measurement_start, 1, 10)) AS date,
-    SUM(COALESCE(total_after_discount, amount * discount_rate)) AS cost
-  FROM sys.information_schema.instance_usage
-  GROUP BY 1
-),
-historical_median AS (
-  SELECT percentile_approx(cost, 0.5) AS median_cost
-  FROM daily_costs
-  WHERE date BETWEEN date_sub(current_date(), 31) AND current_date() - INTERVAL 2 DAY
-),
-yesterday_cost AS (
-  SELECT COALESCE(cost, 0) AS cost
-  FROM daily_costs
-  WHERE date = current_date() - INTERVAL 1 DAY
-)
-SELECT
-  CASE
-    WHEN h.median_cost IS NULL OR h.median_cost = 0 THEN 9999.0
-    ELSE ROUND(y.cost / h.median_cost, 2)
-  END AS cost_ratio
-FROM yesterday_cost y
-CROSS JOIN historical_median h
-```
-
-**告警配置**：
-* 预期结果 ≤ 1.5（即昨日费用不超过历史中位数的1.5倍）
-* 可根据业务特点调整倍数：
-  * 1.5倍：敏感监控
-  * 2.0倍：常规监控
-  * 3.0倍：宽松监控
-
-**基线阈值辅助分析SQL**：
-
-如果不确定预期结果的合理值，可执行以下 SQL，取过去 30 天的 tp90、tp95 和 tp99 值作为参考：
-
-```SQL
--- 分析历史费用波动，帮助确定合理的告警倍数
-WITH daily_costs AS (
-  SELECT
-    to_date(substr(measurement_start, 1, 10)) AS date,
-    SUM(COALESCE(total_after_discount, amount * discount_rate)) AS daily_cost
-  FROM sys.information_schema.instance_usage
-  WHERE to_date(substr(measurement_start, 1, 10)) >= date_sub(current_date(), 60)
-    AND to_date(substr(measurement_start, 1, 10)) < current_date()
-  GROUP BY 1
-),
--- 计算过去30天的整体中位数作为基线
-baseline AS (
-  SELECT percentile_approx(daily_cost, 0.5) AS median_cost
-  FROM daily_costs
-  WHERE date >= date_sub(current_date(), 31)
-    AND date < current_date()
-),
--- 计算每日费用与基线的比值
-ratio_analysis AS (
-  SELECT
-    d.date,
-    d.daily_cost,
-    b.median_cost,
-    CASE 
-      WHEN b.median_cost > 0 THEN ROUND(d.daily_cost / b.median_cost, 2)
-      ELSE NULL
-    END AS cost_ratio
-  FROM daily_costs d
-  CROSS JOIN baseline b
-  WHERE d.date >= date_sub(current_date(), 30)
-)
-SELECT
-  '历史费用波动分析' AS analysis_type,
-  COUNT(*) AS total_days,
-  ROUND(MIN(cost_ratio), 2) AS min_ratio,
-  ROUND(percentile_approx(cost_ratio, 0.25), 2) AS p25_ratio,
-  ROUND(percentile_approx(cost_ratio, 0.5), 2) AS p50_ratio,
-  ROUND(percentile_approx(cost_ratio, 0.75), 2) AS p75_ratio,
-  ROUND(percentile_approx(cost_ratio, 0.90), 2) AS p90_ratio,
-  ROUND(percentile_approx(cost_ratio, 0.95), 2) AS p95_ratio,
-  ROUND(percentile_approx(cost_ratio, 0.99), 2) AS p99_ratio,
-  ROUND(MAX(cost_ratio), 2) AS max_ratio
-FROM ratio_analysis
-
-UNION ALL
-
--- 基于历史波动计算建议阈值
-SELECT
-  '建议告警阈值' AS analysis_type,
-  NULL AS total_days,
-  NULL AS min_ratio,
-  NULL AS p25_ratio,
-  NULL AS p50_ratio,
-  NULL AS p75_ratio,
-  ROUND(
-    (SELECT percentile_approx(cost_ratio, 0.90) * 1.2 FROM ratio_analysis), 
-    2
-  ) AS p90_ratio,  -- 敏感监控
-  ROUND(
-    (SELECT percentile_approx(cost_ratio, 0.95) * 1.1 FROM ratio_analysis), 
-    2
-  ) AS p95_ratio,  -- 常规监控
-  ROUND(
-    (SELECT percentile_approx(cost_ratio, 0.99) * 1.05 FROM ratio_analysis), 
-    2
-  ) AS p99_ratio,  -- 宽松监控
-  NULL AS max_ratio;
-```
-
-## 监控效果验证
-
-1. **手动测试**：配置质量规则后，可进行试跑，以验证质量规则配置和 SQL 的正确性。
-2. **告警测试**：在试跑测试时，可（手动）触发告警以验证通知功能，从而确认通知策略配置正确。
-3. **历史回溯**：查看过去 7 天的费用数据，确认阈值的合理性。
-
-通过以上步骤，您可以快速搭建费用异常告警系统，有效控制成本风险。

-
-***
-
-## 📊 数据类型设计策略
-
-### 数值类型选择指南
-
-#### 自增主键设计
-
-**关键限制**: IDENTITY列仅支持BIGINT类型
-
-```sql
--- 正确的IDENTITY使用(唯一支持的语法)
-CREATE TABLE business_events (
-    event_id BIGINT IDENTITY,              -- 仅支持BIGINT类型
-    event_data JSON,
-    created_at TIMESTAMP DEFAULT current_timestamp()
-);
-
--- 带种子值的IDENTITY
-CREATE TABLE user_accounts (
-    user_id BIGINT IDENTITY(1000),         -- 从1000开始自增
-    username VARCHAR(50) NOT NULL
-);
-```
-
-**不支持的IDENTITY语法(测试确认会失败**):
-
-```sql
--- 这些都会导致错误：invalid identity column type int, currently only BIGINT is supported
-CREATE TABLE wrong_examples (
-    id INT IDENTITY,                       -- 失败
-    small_id SMALLINT IDENTITY,            -- 失败  
-    str_id VARCHAR(50) IDENTITY            -- 失败
-);
-```
-
-#### 业务数值字段选择
-
-| 数据类型           | 存储空间 | 数值范围             | 推荐场景     | 实际应用示例                     |
-| -------------- | ---- | ---------------- | -------- | -------------------------- |
-| `TINYINT`      | 1字节  | -128 到 127       | 状态码、等级   | `status TINYINT DEFAULT 1` |
-| `SMALLINT`     | 2字节  | -32,768 到 32,767 | 年份、计数器   | `birth_year SMALLINT`      |
-| `INT`          | 4字节  | ±21亿             | 业务ID、大计数 | `user_id INT NOT NULL`     |
-| `BIGINT`       | 8字节  | ±922万万亿          | 自增主键、大数值 | `id BIGINT IDENTITY`       |
-| `DECIMAL(p,s)` | 变长   | 最高精度38位          | 金融计算     | `amount DECIMAL(15,2)`     |
-| `FLOAT`        | 4字节  | 单精度浮点            | 科学计算、坐标  | `temperature FLOAT`        |

-
-### 字符串类型策略
-
-#### 长度规划原则（基于实际业务需求）
-
-| 业务场景  | 推荐类型            | 长度设置      | 实际覆盖率 | 设计考量              |
-| ----- | --------------- | --------- | ----- | ----------------- |
-| 邮箱地址  | `VARCHAR(320)`  | RFC5321标准 | 99.9% | 国际标准长度            |
-| 用户名   | `VARCHAR(50)`   | 实际调研      | 99.5% | 平衡存储和使用           |

-| 商品描述  | `VARCHAR(2000)` | 电商需求      | 90%   | 详情页展示             |
-| 长文本内容 | `STRING`        | 不限长度      | 100%  | 博客、评论等            |
-
-```sql
--- 字符串类型最佳实践
-CREATE TABLE user_profiles (
-    user_id BIGINT IDENTITY,
-    
-    -- 固定格式使用CHAR
-    country_code CHAR(2),                   -- CN, US, JP
-    currency_code CHAR(3),                  -- USD, CNY, EUR
-    
-    -- 业务字段使用合理的VARCHAR长度
-    username VARCHAR(50) NOT NULL,
-    email VARCHAR(320) NOT NULL,
-    mobile_phone VARCHAR(20),
-    
-    -- 描述性内容
-    nickname VARCHAR(100),
-    bio VARCHAR(500),                       -- 个人简介
-    full_description STRING,                -- 详细描述，长度不定
-    
-    -- 结构化数据
-    preferences JSON DEFAULT '{}'
-);
-```
-
-### 向量类型应用场景
-
-#### 向量类型语法和应用
-
-**标准语法**: `VECTOR(scalar_type, dimension)` 或 `VECTOR(dimension)`
-
-| 标量类型      | 存储开销  | 适用场景      | 维度推荐     | 应用示例                   |
-| --------- | ----- | --------- | -------- | ---------------------- |
-| `FLOAT`   | 4字节/维 | 语义向量、通用AI | 128-2048 | `VECTOR(FLOAT, 768)`   |
-| `INT`     | 4字节/维 | 离散特征、计数向量 | 64-1024  | `VECTOR(INT, 256)`     |
-| `TINYINT` | 1字节/维 | 压缩向量、移动端  | 64-512   | `VECTOR(TINYINT, 128)` |
-
-**实际应用案例**:
-
-```sql
-CREATE TABLE ai_content_vectors (
-    content_id BIGINT IDENTITY,
-    content_type VARCHAR(50),
-    
-    -- 不同业务场景的向量配置
-    text_embedding VECTOR(FLOAT, 768),      -- BERT/RoBERTa输出
-    image_features VECTOR(FLOAT, 512),      -- ResNet/CNN特征
-    user_preference VECTOR(INT, 256),       -- 推荐系统用户画像
-    mobile_compact VECTOR(TINYINT, 128),    -- 移动端轻量化
-    general_vector VECTOR(512)              -- 默认FLOAT类型
-);
-
--- 向量数据插入语法（注意：维度必须严格匹配）
-INSERT INTO ai_content_vectors (content_type, text_embedding) VALUES (
-    'document',
-    cast(concat('[', repeat('0.1,', 767), '0.1]') as VECTOR(FLOAT, 768))
-);
-```
-
-### 复杂数据类型使用指南
-
-#### STRUCT类型正确使用
-
-**正确的STRUCT数据插入语法**:
-
-```sql
-CREATE TABLE user_complex_data (
-    user_id BIGINT IDENTITY,
-    
-    -- 简单结构体
-    basic_info STRUCT<id:INT, name:STRING, age:INT>,
-    
-    -- 复杂嵌套结构体  
-    detailed_profile STRUCT<
-        personal:STRUCT<name:STRING, email:STRING>,
-        address:STRUCT<city:STRING, country:STRING>,
-        preferences:MAP<STRING, STRING>
-    >
-);
-
--- 方法1：使用struct函数（按位置传参）
-INSERT INTO user_complex_data (basic_info) VALUES (
-    struct(123, 'Alice', 25)
-);
-
--- 方法2：使用named_struct函数（推荐，明确字段名）
-INSERT INTO user_complex_data (basic_info) VALUES (
-    named_struct('id', 123, 'name', 'Alice', 'age', 25)
-);
-
--- 复杂嵌套结构的插入
-INSERT INTO user_complex_data (detailed_profile) VALUES (
-    named_struct(
-        'personal', named_struct('name', 'Bob', 'email', 'bob@test.com'),
-        'address', named_struct('city', 'Shanghai', 'country', 'China'),
-        'preferences', map('lang', 'zh', 'theme', 'dark')
-    )
-);
-```
-
-#### ARRAY和MAP类型使用
-
-```sql
-CREATE TABLE collection_types_demo (
-    record_id BIGINT IDENTITY,
-    
-    -- 数组类型
-    tags ARRAY<STRING>,
-    scores ARRAY<INT>,
-    nested_arrays ARRAY<ARRAY<STRING>>,
-    
-    -- 映射类型
-    config MAP<STRING, STRING>,
-    metrics MAP<STRING, DOUBLE>,
-    complex_map MAP<STRING, ARRAY<INT>>
-);
-
--- 正确的插入语法
-INSERT INTO collection_types_demo (
-    tags, scores, nested_arrays, config, metrics, complex_map
-) VALUES (
-    array('tech', 'AI', 'database'),                    -- 字符串数组
-    array(85, 92, 78),                                  -- 整数数组
-    array(array('group1', 'item1'), array('group2', 'item2')), -- 嵌套数组
-    map('env', 'prod', 'version', 'v2.2'),             -- 字符串映射
-    map('cpu_usage', 0.75, 'memory_usage', 0.60),      -- 数值映射
-    map('feature1', array(1, 2, 3), 'feature2', array(4, 5, 6)) -- 复杂映射
-);
-```

-## 🏗️ 表结构设计模式
-
-### 约束设计策略
-
-#### NOT NULL约束的合理应用
-
-NOT NULL约束不仅保障数据完整性，更是查询优化器的重要提示:
-
-```sql
-CREATE TABLE order_management (
-    order_id BIGINT IDENTITY,
-    
-    -- 业务核心字段：必须非空
-    customer_id INT NOT NULL,               -- 核心业务关联
-    order_time TIMESTAMP NOT NULL,         -- 核心时间维度
-    order_status TINYINT NOT NULL DEFAULT 0, -- 业务状态
-    total_amount DECIMAL(12,2) NOT NULL,    -- 核心金额字段
-    
-    -- 可选业务字段：允许为空
-    coupon_code VARCHAR(20),               -- 优惠券（可选）
-    customer_notes VARCHAR(500),           -- 客户备注（可选）
-    gift_message VARCHAR(200),             -- 礼品留言（可选）
-    
-    -- 系统字段：非空且有默认值
-    created_at TIMESTAMP NOT NULL DEFAULT current_timestamp(),
-    updated_at TIMESTAMP,                  -- 更新时间（首次为NULL）
-    
-    -- 分区字段（生成列）
-    date_partition STRING GENERATED ALWAYS AS (
-        date_format(order_time, 'yyyy-MM-dd')
-    )
-) 
-PARTITIONED BY (date_partition);
-```
-
-#### 默认值的使用
-
-默认值设计应当反映业务逻辑和系统行为:
-
-```sql
-CREATE TABLE user_account_enhanced (
-    user_id BIGINT IDENTITY,
-    username VARCHAR(50) NOT NULL,
-    
-    -- 业务状态的合理默认值
-    account_status TINYINT DEFAULT 1,      -- 1=正常, 0=禁用, 2=锁定
-    email_verified BOOLEAN DEFAULT false,  -- 默认未验证
-    phone_verified BOOLEAN DEFAULT false,  -- 默认未验证
-    
-    -- 数值字段的业务默认值
-    credit_balance DECIMAL(10,2) DEFAULT 0.00,  -- 默认余额为0
-    loyalty_points INT DEFAULT 0,               -- 默认积分为0
-    login_attempts TINYINT DEFAULT 0,           -- 默认登录尝试次数
-    
-    -- 时间字段的系统默认值
-    registration_time TIMESTAMP DEFAULT current_timestamp(),
-    last_login_time TIMESTAMP,             -- 首次登录前为NULL
-    password_changed_at TIMESTAMP DEFAULT current_timestamp(),
-    
-    -- JSON字段的默认值
-    user_preferences JSON DEFAULT '{}',    -- 默认空对象
-    security_settings JSON DEFAULT '{"two_factor": false, "login_notifications": true}'
-);
-```

-
-#### 时间序列分区模式
-
-**模式1: 按日分区（推荐，最常用**）
-
-```sql
-CREATE TABLE daily_business_logs (
-    log_id BIGINT IDENTITY,
-    application VARCHAR(50) NOT NULL,
-    log_level VARCHAR(10) NOT NULL,
-    message STRING,
-    user_id INT,
-    log_timestamp TIMESTAMP NOT NULL,
-    
-    -- 使用生成列创建日期分区键
-    date_partition STRING GENERATED ALWAYS AS (
-        date_format(log_timestamp, 'yyyy-MM-dd')
-    )
-) 
-PARTITIONED BY (date_partition)
-HASH CLUSTERED BY (application)
-SORTED BY (log_timestamp DESC)
-INTO 128 BUCKETS
-COMMENT '业务日志表 - 按日期分区，便于日志管理和查询';
-```
-
-**模式2: 按小时分区（高频数据**）
-
-```sql
-CREATE TABLE realtime_metrics (
-    metric_id BIGINT IDENTITY,
-    sensor_id VARCHAR(100) NOT NULL,
-    metric_value DOUBLE,
-    collect_time TIMESTAMP NOT NULL,
-    
-    -- 按小时分区，适合实时监控
-    hour_partition STRING GENERATED ALWAYS AS (
-        date_format(collect_time, 'yyyy-MM-dd-HH')
-    )
-) 
-PARTITIONED BY (hour_partition)
-HASH CLUSTERED BY (sensor_id)
-SORTED BY (collect_time DESC)
-INTO 512 BUCKETS
-COMMENT '实时指标表 - 按小时分区，支持高频数据写入';
-```
-
-**模式3: 按月分区（历史归档**）
-
-```sql
-CREATE TABLE monthly_report_data (
-    report_id BIGINT IDENTITY,
-    business_data JSON,
-    created_time TIMESTAMP NOT NULL,
-    
-    -- 按月分区，减少分区数量
-    month_partition STRING GENERATED ALWAYS AS (
-        date_format(created_time, 'yyyy-MM')
-    )
-) 
-PARTITIONED BY (month_partition)
-COMMENT '月度报表数据 - 按月分区，优化长期存储';
-```
-
-#### 业务维度分区模式
-
-**多租户分区模式**:
-
-```sql
-CREATE TABLE saas_tenant_data (
-    record_id BIGINT IDENTITY,
-    tenant_id VARCHAR(50) NOT NULL,
-    entity_type VARCHAR(50) NOT NULL,
-    entity_data JSON,
-    created_time TIMESTAMP DEFAULT current_timestamp(),
-    
-    -- 按租户分区，实现数据隔离
-    tenant_partition STRING GENERATED ALWAYS AS (tenant_id)
-) 
-PARTITIONED BY (tenant_partition)
-HASH CLUSTERED BY (entity_type)
-SORTED BY (created_time DESC)
-INTO 64 BUCKETS
-COMMENT '多租户数据表 - 按租户ID分区，实现完全数据隔离';
-```
-
-**地理区域分区模式**:
-
-```sql
-CREATE TABLE global_order_data (
-    order_id BIGINT IDENTITY,
-    customer_id INT NOT NULL,
-    region VARCHAR(50) NOT NULL,            -- 地理区域
-    country VARCHAR(50) NOT NULL,
-    order_data JSON,
-    order_time TIMESTAMP
-) 
-PARTITIONED BY (region)                    -- 按区域分区
-HASH CLUSTERED BY (customer_id)
-SORTED BY (order_time DESC)
-INTO 128 BUCKETS
-COMMENT '全球订单数据 - 按地理区域分区，支持区域化查询';
-```
-
-#### 复合分区策略（高级应用）
-
-**时间+业务维度双重分区**:
-
-```sql
-CREATE TABLE advanced_partitioning_example (
-    event_id BIGINT IDENTITY,
-    user_id INT NOT NULL,
-    business_type VARCHAR(50) NOT NULL,
-    event_time TIMESTAMP NOT NULL,
-    event_data JSON,
-    
-    -- 复合分区键
-    date_partition STRING GENERATED ALWAYS AS (date_format(event_time, 'yyyy-MM-dd')),
-    business_partition STRING GENERATED ALWAYS AS (business_type)
-) 
-PARTITIONED BY (date_partition, business_partition)  -- 双重分区
-HASH CLUSTERED BY (user_id)
-SORTED BY (event_time DESC)
-INTO 256 BUCKETS
-COMMENT '高级分区示例 - 时间和业务维度双重分区';
-```
-
-### 分区管理和优化
-
-#### 动态分区限制
-
-**关键限制**: 单个插入任务最多创建2048个动态分区
-
-```sql
--- 可能超出限制的操作
-INSERT INTO large_partition_table 
-SELECT * FROM source_table_with_many_partitions;  -- 如果source表分区数>2048会失败
-
--- 解决方案1: 分批插入
-INSERT INTO large_partition_table 
-SELECT * FROM source_table_with_many_partitions 
-WHERE date_column BETWEEN '2024-01-01' AND '2024-01-10';  -- 限制分区范围
-
--- 解决方案2: 循环插入（应用层实现）
--- 在应用程序中按日期/区域等维度分批插入，每批控制在2000个分区以内
-```
-
-#### 数据生命周期管理
-
-```sql
--- 设置表级数据生命周期
-CREATE TABLE lifecycle_managed_table (
-    record_id BIGINT IDENTITY,
-    business_data JSON,
-    created_time TIMESTAMP,
-    
-    date_partition STRING GENERATED ALWAYS AS (date_format(created_time, 'yyyy-MM-dd'))
-) 
-PARTITIONED BY (date_partition)
-PROPERTIES ('data_lifecycle' = '90')      -- 90天后自动清理
-COMMENT '生命周期管理表 - 90天数据保留策略';
-```
-

-
-## 🪣 分桶与排序优化
-
-### 分桶策略设计
-
-#### 分桶数量规划指南
-
-基于实际测试验证的分桶配置建议:
-
-| 数据规模     | 建议桶数     | 单桶目标大小  | 适用场景      | 测试验证结果 |
-| -------- | -------- | ------- | --------- | ------ |
-| < 10GB   | 16-32    | \~512MB | 小型业务表、维度表 | 测试通过   |
-| 10GB-1TB | 64-256   | \~1GB   | 主要业务表、事实表 | 测试通过   |
-| 1TB-10TB | 256-1024 | \~2GB   | 大型分析表、历史表 | 推荐配置   |
-| > 10TB   | 1024+    | \~4GB   | 超大数据仓库表   | 架构支持   |
-
-#### 分桶列选择原则
-
-1. **高基数原则**: 选择值分布均匀、基数高的列
-2. **查询亲和性**: 优先选择JOIN和GROUP BY中的关键列
-3. **写入均衡**: 避免数据倾斜和写入热点
-
-```sql
--- 最佳实践：用户行为分析表
-CREATE TABLE user_behavior_optimized (
-    behavior_id BIGINT IDENTITY,
-    user_id INT NOT NULL,                   -- 高基数，分布均匀
-    session_id VARCHAR(100) NOT NULL,
-    behavior_type VARCHAR(50),              -- 浏览、点击、购买等
-    behavior_time TIMESTAMP NOT NULL,
-    product_id INT,
-    
-    -- 分区策略
-    date_partition STRING GENERATED ALWAYS AS (date_format(behavior_time, 'yyyy-MM-dd'))
-) 
-PARTITIONED BY (date_partition)
-HASH CLUSTERED BY (user_id)               -- 用户维度分桶，支持用户行为分析
-SORTED BY (behavior_time DESC, behavior_type ASC)  -- 时间倒序+行为类型排序  
-INTO 256 BUCKETS;                         -- 适合中大型数据量
-
--- 索引优化
-CREATE BLOOMFILTER INDEX user_lookup_idx ON TABLE user_behavior_optimized(user_id);
-CREATE BLOOMFILTER INDEX product_filter_idx ON TABLE user_behavior_optimized(product_id);
-CREATE INVERTED INDEX behavior_type_idx ON TABLE user_behavior_optimized(behavior_type);
-```
-
-### 排序策略优化
-
-排序字段的选择直接影响查询性能，特别是范围查询和TOP-N查询:
-
-```sql
--- 金融交易表的排序优化
-CREATE TABLE financial_transactions_optimized (
-    transaction_id BIGINT IDENTITY,
-    account_id INT NOT NULL,
-    transaction_time TIMESTAMP NOT NULL,
-    amount DECIMAL(15,2) NOT NULL,
-    transaction_type VARCHAR(20) NOT NULL,
-    risk_score DECIMAL(5,3),

-### 布隆过滤器索引应用（高基数列优化）
-
-#### 适用场景分析
-
-| 使用场景    | 基数特征      | 查询模式    | 优化效果  | 实际应用    |
-| ------- | --------- | ------- | ----- | ------- |
-| 用户ID查找  | 极高基数(百万+) | = 精确匹配  | 显著提升  | 用户行为分析  |
-| 邮箱地址验证  | 高基数，唯一性强  | = 存在性检查 | 快速过滤  | 注册去重验证  |
-| 商品SKU检索 | 高基数，业务唯一  | = 库存查询  | 快速定位  | 电商库存系统  |
-| 订单号查询   | 极高基数，唯一   | = 订单查找  | 毫秒级响应 | 订单管理系统  |
-| 设备ID监控  | 高基数，设备唯一  | = 设备状态  | 高效过滤  | IoT监控平台 |
-
-#### 布隆过滤器最佳实践
-
-```sql
--- 高基数用户管理表
-CREATE TABLE user_management_optimized (
-    user_id BIGINT IDENTITY,
-    username VARCHAR(50) NOT NULL,
-    email VARCHAR(320) NOT NULL,
-    mobile_phone VARCHAR(20),
-    id_card_hash VARCHAR(64),               -- 身份证号哈希
-    device_fingerprint VARCHAR(200),        -- 设备指纹
-    
-    -- 核心业务字段
-    registration_date DATE,
-    last_login_time TIMESTAMP,
-    account_status TINYINT DEFAULT 1,       -- 1=正常, 0=禁用, 2=锁定
-    verification_level TINYINT DEFAULT 0    -- 0=未验证, 1=邮箱, 2=手机, 3=实名
-);
-
--- 高基数字段的布隆过滤器索引
-CREATE BLOOMFILTER INDEX username_bloom_idx 
-ON TABLE user_management_optimized(username);
-
-CREATE BLOOMFILTER INDEX email_bloom_idx 
-ON TABLE user_management_optimized(email);
-
-CREATE BLOOMFILTER INDEX phone_bloom_idx 
-ON TABLE user_management_optimized(mobile_phone);
-
-CREATE BLOOMFILTER INDEX idcard_bloom_idx 
-ON TABLE user_management_optimized(id_card_hash);
-
-CREATE BLOOMFILTER INDEX device_bloom_idx 
-ON TABLE user_management_optimized(device_fingerprint);
-
--- 实际查询应用示例
--- 1. 用户注册时的快速查重
-SELECT COUNT(*) FROM user_management_optimized 
-WHERE email = 'newuser@example.com';        -- 布隆过滤器快速过滤
-
--- 2. 用户登录时的快速定位
-SELECT user_id, account_status, verification_level 
-FROM user_management_optimized 
-WHERE username = 'target_username';         -- 布隆过滤器加速查找
-
--- 3. 设备风控检查
-SELECT user_id, COUNT(*) as device_usage_count
-FROM user_management_optimized 
-WHERE device_fingerprint = 'specific_device_fp'  -- 布隆过滤器快速匹配
-GROUP BY user_id;
-```
-
-### 索引命名和管理规范
-
-#### 索引命名最佳实践
-
-**重要更新**: 经过实际测试验证，当前版本的云器Lakehouse在索引命名方面**严格强制schema级唯一性**。
-
-#### 推荐的索引命名规范
-
-**命名格式**: `{table_name}_{index_type}_{column_name}_idx`
-
-**索引类型缩写**:
-
-* `vec` - 向量索引 (VECTOR INDEX)
-* `inv` - 倒排索引 (INVERTED INDEX)
-* `bloom` - 布隆过滤器索引 (BLOOMFILTER INDEX)
-
-```sql
--- 正确的索引命名实践
-CREATE TABLE product_catalog (
-    product_id INT,
-    product_name VARCHAR(200),
-    description STRING,
-    category VARCHAR(100),
-    price DECIMAL(10,2),
-    features_vector VECTOR(FLOAT, 512)
-);
-
--- 唯一且描述性的索引名称
-CREATE VECTOR INDEX products_vec_features_idx 
-ON TABLE product_catalog(features_vector)
-PROPERTIES ("distance.function" = "cosine_distance");
-
-CREATE INVERTED INDEX products_inv_name_idx 
-ON TABLE product_catalog(product_name)
-PROPERTIES ('analyzer' = 'chinese');
-
-CREATE INVERTED INDEX products_inv_desc_idx 
-ON TABLE product_catalog(description)
-PROPERTIES ('analyzer' = 'unicode');
-
-CREATE BLOOMFILTER INDEX products_bloom_category_idx 
-ON TABLE product_catalog(category);
-
--- 另一个表使用不同的索引名称前缀
-CREATE TABLE user_content (
-    content_id BIGINT IDENTITY,
-    content_text STRING,
-    content_vector VECTOR(FLOAT, 768)
-);
-
-CREATE VECTOR INDEX users_vec_content_idx       -- 不同的表名前缀
-ON TABLE user_content(content_vector)
-PROPERTIES ("distance.function" = "cosine_distance");
-
-CREATE INVERTED INDEX users_inv_text_idx        -- 不同的表名前缀
-ON TABLE user_content(content_text)
-PROPERTIES ('analyzer' = 'chinese');
-```
-
-### 索引功能限制说明
-
-#### IF NOT EXISTS语法当前状态
-
-根据最新测试验证，索引创建语法当前**不支持** IF NOT EXISTS选项：
-
-```sql
--- 不支持的索引IF NOT EXISTS语法（会导致语法错误）
-CREATE VECTOR INDEX IF NOT EXISTS vec_idx 
-ON TABLE example_table(embedding)
-PROPERTIES ("distance.function" = "cosine_distance");
-
-CREATE INVERTED INDEX IF NOT EXISTS text_idx
-ON TABLE example_table(content) 
-PROPERTIES ('analyzer'='chinese');
-
-CREATE BLOOMFILTER INDEX IF NOT EXISTS bloom_idx
-ON TABLE example_table(user_id);
-```
-
-在创建索引前，建议先检查索引是否存在，避免错误：
-
-```sql
--- 推荐做法：先检查索引是否存在
--- 然后再创建
-CREATE VECTOR INDEX vec_idx ON TABLE example_table(embedding)
-PROPERTIES ("distance.function" = "cosine_distance");
-```
-
-#### ARRAY类型列上的索引限制
-
-通过测试确认，在ARRAY类型列上创建倒排索引时存在以下限制：
-
-```sql
--- ARRAY类型列不支持指定analyzer参数
-CREATE TABLE array_column_table (
-    id INT,
-    tags ARRAY<STRING>
-);
-
--- 错误：ARRAY类型列指定analyzer
-CREATE INVERTED INDEX tags_analyzer_idx 
-ON TABLE array_column_table(tags)
-PROPERTIES ('analyzer' = 'keyword');  -- 失败！
-
--- 正确：ARRAY类型列不指定analyzer
-CREATE INVERTED INDEX tags_idx 
-ON TABLE array_column_table(tags);  -- 成功
-
--- 替代方案：使用STRING类型存储标签
-CREATE TABLE string_tags_table (
-    id INT,
-    tags_str STRING  -- 使用逗号分隔的标签字符串
-);
-
-CREATE INVERTED INDEX tags_str_idx 
-ON TABLE string_tags_table(tags_str)
-PROPERTIES ('analyzer' = 'keyword');  -- 成功
-```

-## ⚡ 性能优化策略
-
-### 查询性能优化技巧
-
-#### 分区剪枝优化
-
-确保查询条件能够有效利用分区剪枝:
-
-```sql
--- 优秀的查询模式：充分利用分区剪枝
-SELECT user_id, COUNT(*) as activity_count,
-       AVG(session_duration) as avg_duration
-FROM user_activity_logs 
-WHERE date_partition BETWEEN '2024-01-01' AND '2024-01-31'  -- 分区剪枝
-  AND user_id IN (12345, 67890, 54321)                       -- 分桶定位
-  AND activity_type = 'purchase'                             -- 索引过滤
-GROUP BY user_id
-ORDER BY activity_count DESC;
-
--- 避免的查询模式：无法利用分区剪枝
-SELECT user_id, COUNT(*) as activity_count
-FROM user_activity_logs 
-WHERE activity_time >= '2024-01-01 00:00:00'  -- 直接使用时间列，无法分区剪枝
-  AND activity_time <= '2024-01-31 23:59:59'
-GROUP BY user_id;
-```

-
-### 分区设计陷阱
-
-#### 陷阱4：不支持的分区列类型
-
-**错误场景**:
-
-```sql
--- 不支持的分区列类型（测试确认会失败）
-CREATE TABLE partition_type_errors (
-    id INT,
-    amount DECIMAL(10,2),               -- DECIMAL不支持直接分区
-    price DOUBLE,                       -- DOUBLE不支持分区
-    created_time TIMESTAMP,             -- TIMESTAMP不能直接分区

-
-**正确解决方案**:
-
-```sql
--- 使用生成列转换为支持的分区类型
-CREATE TABLE partition_type_solutions (
-    id INT,
-    amount DECIMAL(10,2),
-    price DOUBLE,

-
-#### 陷阱5：动态分区数量超限
-
-**问题场景**:
-
-```sql
--- 可能导致动态分区超限的操作
-INSERT INTO large_partition_table 
-SELECT * FROM source_table_with_many_dates;  -- 如果源表包含>2048个不同日期会失败
-
--- 错误信息：
--- The count of dynamic partitions exceeds the maximum number 2048
-```
-
-**解决方案策略**:
-
-```sql
--- 策略1：分批按时间范围插入
-INSERT INTO large_partition_table 
-SELECT * FROM source_table_with_many_dates 
-WHERE event_date BETWEEN '2024-01-01' AND '2024-01-10';  -- 限制分区范围
-
-INSERT INTO large_partition_table 
-SELECT * FROM source_table_with_many_dates 
-WHERE event_date BETWEEN '2024-02-01' AND '2024-02-29';  -- 第二批：29个分区
-
--- 策略2：按分区值分批插入
-INSERT INTO large_partition_table 
-SELECT * FROM source_table_with_many_dates 
-WHERE region IN ('north', 'south', 'east', 'west');     -- 限制为4个分区
-
--- 策略3：预先过滤数据
-WITH filtered_source AS (
-    SELECT *, 
-           date_format(event_timestamp, 'yyyy-MM-dd') as date_part
-    FROM source_table_with_many_dates 
-    WHERE event_timestamp >= '2024-01-01'                -- 预过滤减少分区数
-      AND event_timestamp < '2024-02-01'
-)
-INSERT INTO large_partition_table 
-SELECT * FROM filtered_source;
-
--- 策略4：应用层循环控制（伪代码）
--- for month in ['2024-01', '2024-02', ...]:
---     INSERT INTO table SELECT * FROM source WHERE month_partition = month
-```
-
-### 索引设计陷阱
-
-#### 陷阱6：索引命名管理
-
-**重要更新**: 经测试验证，当前版本的云器Lakehouse严格强制schema级索引名称唯一性。
-
-**推荐的命名实践**:
-
-```sql
--- 使用表名前缀的唯一索引命名
-CREATE TABLE orders (
-    order_id INT,
-    customer_id INT,
-    order_content STRING
-);
-CREATE INVERTED INDEX orders_inv_customer_idx ON TABLE orders(customer_id);
-CREATE INVERTED INDEX orders_inv_content_idx ON TABLE orders(order_content) 
-PROPERTIES('analyzer'='keyword');
-
-CREATE TABLE products (
-    product_id INT,
-    customer_id INT,
-    product_description STRING
-);
-CREATE INVERTED INDEX products_inv_customer_idx ON TABLE products(customer_id);
-CREATE INVERTED INDEX products_inv_desc_idx ON TABLE products(product_description) 
-PROPERTIES('analyzer'='chinese');
-
--- 推荐的索引命名规范
--- 格式：{table_name}_{index_type}_{column_name}_idx
--- 示例：users_bloom_email_idx, orders_vec_features_idx
-```
-
-#### 陷阱7：PRIMARY KEY约束与HASH CLUSTERED BY冲突
-
-**问题场景**:
-
-```sql
--- PRIMARY KEY约束与HASH CLUSTERED BY冲突
-CREATE TABLE table_with_conflict (
-    tenant_id VARCHAR(50) PRIMARY KEY,
-    tenant_name VARCHAR(200) NOT NULL,
-    tenant_status TINYINT DEFAULT 1
-) 
-HASH CLUSTERED BY (tenant_id)            -- 与PRIMARY KEY冲突
-INTO 32 BUCKETS;
-
--- 错误信息：CLUSTERED BY definition conflicts with enforced PRIMARY KEY
--- or UNIQUE constraints defined at :[31,2], must HASH CLUSTERED BY ... SORTED BY ... ASC
--- with all PRIMARY KEY or UNIQUE columns
-```
-
-**解决方案**:
-
-```sql
--- 方案1：移除PRIMARY KEY约束，使用普通非空列
-CREATE TABLE solution_remove_pk (
-    tenant_id VARCHAR(50) NOT NULL,       -- 移除PRIMARY KEY
-    tenant_name VARCHAR(200) NOT NULL,
-    tenant_status TINYINT DEFAULT 1
-) 
-HASH CLUSTERED BY (tenant_id)
-INTO 32 BUCKETS;
-
--- 方案2：调整HASH CLUSTERED BY与SORTED BY以符合要求
-CREATE TABLE solution_adjust_cluster (
-    tenant_id VARCHAR(50) PRIMARY KEY,
-    tenant_name VARCHAR(200) NOT NULL,
-    tenant_status TINYINT DEFAULT 1
-) 
-HASH CLUSTERED BY (tenant_id)            -- 保持与PRIMARY KEY一致
-SORTED BY (tenant_id ASC)                -- 添加排序且为ASC
-INTO 32 BUCKETS;
-```
-
-#### PRIMARY KEY与分桶策略最佳实践
-
-基于测试验证的结果，我们建议遵循以下设计指导：
-
-1. **避免同时使用**：在大多数场景下，建议避免同时使用PRIMARY KEY约束和HASH CLUSTERED BY，而是选择其中一种：
-   * 对于需要唯一性约束的场景，使用PRIMARY KEY
-   * 对于需要性能优化的大表，使用HASH CLUSTERED BY和布隆过滤器索引
-
-2. **必须同时使用时的规则**：如果业务需要同时使用，必须满足以下全部条件：
-   * HASH CLUSTERED BY的列必须包含PRIMARY KEY的全部列
-   * 必须添加SORTED BY子句
-   * SORTED BY子句必须包含PRIMARY KEY的全部列
-   * SORTED BY的所有PRIMARY KEY列都必须使用ASC排序方向
-
-3. **示例参考**：
-
-```sql
--- 最佳实践1：仅使用PRIMARY KEY（小表推荐）
-CREATE TABLE customer_profiles (
-    customer_id INT PRIMARY KEY,
-    customer_name VARCHAR(100) NOT NULL,
-    customer_email VARCHAR(200)
-);
-
--- 最佳实践2：仅使用HASH CLUSTERED BY（大表推荐）
-CREATE TABLE customer_events (
-    event_id BIGINT IDENTITY,
-    customer_id INT NOT NULL,
-    event_type VARCHAR(50),
-    event_time TIMESTAMP
-)
-HASH CLUSTERED BY (customer_id)
-SORTED BY (event_time DESC)
-INTO 128 BUCKETS;
-
--- 创建布隆过滤器索引实现高效查找
-CREATE BLOOMFILTER INDEX customer_lookup_idx 
-ON TABLE customer_events(customer_id);
-
--- 最佳实践3：必须同时使用时的正确配置
-CREATE TABLE order_items (
-    order_id INT,
-    item_id INT,
-    product_id INT,
-    quantity INT,
-    PRIMARY KEY (order_id, item_id)
-)
-HASH CLUSTERED BY (order_id, item_id)  -- 包含所有PRIMARY KEY列
-SORTED BY (order_id ASC, item_id ASC)  -- 包含所有PRIMARY KEY列且都是ASC
-INTO 64 BUCKETS;
-```
-
-#### 陷阱8：ARRAY类型列上错误使用analyzer
-
-**错误场景**:
-
-```sql
--- 在ARRAY类型列上使用analyzer会导致错误
-CREATE TABLE array_column_table (
-    id INT,
-    tags ARRAY<STRING>
-);
-
-CREATE INVERTED INDEX tags_analyzer_idx 
-ON TABLE array_column_table(tags)
-PROPERTIES ('analyzer' = 'keyword');  -- 失败！ARRAY类型不支持analyzer参数
-
--- 错误信息示例：
--- invalid.inverted.index.analyzer.type, array<string>
-```
-
-**正确解决方案**:
-
-```sql
--- 正确：ARRAY类型列上创建倒排索引时不指定analyzer
-CREATE INVERTED INDEX tags_idx 
-ON TABLE array_column_table(tags);  -- 成功：不指定analyzer
-
--- 或者使用STRING类型存储并使用分隔符
-CREATE TABLE string_tags_table (
-    id INT,
-    tags_str STRING  -- 使用逗号分隔的标签字符串
-);
-
-CREATE INVERTED INDEX tags_str_idx 
-ON TABLE string_tags_table(tags_str)
-PROPERTIES ('analyzer' = 'keyword');  -- 成功：STRING类型支持analyzer
-```
-
-### 生成列设计陷阱
-
-#### 陷阱9：生成列使用非确定性函数
-
-**错误场景**:
-
-```sql
--- 生成列中使用非确定性函数（测试确认会失败）
-CREATE TABLE generated_column_errors (
-    id INT,
-    event_data VARCHAR(1000),
-    
-    -- 以下生成列都会导致创建失败
-    auto_timestamp TIMESTAMP GENERATED ALWAYS AS (current_timestamp()),    -- 失败
-    random_id DOUBLE GENERATED ALWAYS AS (random()),                       -- 失败

-    uuid_value STRING GENERATED ALWAYS AS (uuid())                         -- 失败
-);
-
--- 错误信息：Generated column auto_timestamp only contains built-in/scalar/deterministic function
-```
-
-**正确解决方案**:
-
-```sql
--- 区分生成列和默认值的正确使用
-CREATE TABLE generated_column_solutions (
-    id INT,
-    event_time TIMESTAMP,
-    event_data VARCHAR(1000),

-## 🔧 故障排查指南
-
-### 常见错误诊断和解决方案
-
-#### 错误1：IDENTITY列类型错误
-
-**错误信息**:
-
-```
-invalid identity column type int, currently only BIGINT is supported
-```
-
-**原因分析**: 尝试在非BIGINT列上使用IDENTITY约束
-
-**诊断步骤**:
-
-1. 检查CREATE TABLE语句中的IDENTITY列定义
-2. 确认IDENTITY列的数据类型是否为BIGINT
-3. 检查是否误用了INT、SMALLINT等其他数值类型
-
-**解决方案**:
-
-```sql
--- 错误用法
-CREATE TABLE wrong_table (id INT IDENTITY, name VARCHAR(50));
-
--- 正确用法  
-CREATE TABLE correct_table (id BIGINT IDENTITY, name VARCHAR(50));
-```
-
-#### 错误2：索引命名管理
-
-**重要更新**: 经实际测试验证，当前版本的云器Lakehouse在索引命名方面**可能不严格强制schema级唯一性**。虽然测试中相同名称的索引可以创建成功，但为了代码的可维护性和未来版本兼容性，仍建议使用唯一的索引命名。
-
-**最佳实践**:
-
-```sql
--- 推荐的唯一索引命名
-CREATE INVERTED INDEX table1_inv_content_idx ON TABLE table1(content);
-CREATE INVERTED INDEX table2_inv_content_idx ON TABLE table2(content);
-
--- 命名规范：{table_name}_{index_type}_{column_name}_idx
-```
-
-#### 错误3：生成列函数不支持
-
-**错误信息**:
-
-```
-Generated column auto_timestamp only contains built-in/scalar/deterministic function
-```
-
-**原因分析**: 生成列中使用了非确定性函数
-
-**诊断步骤**:
-
-1. 检查生成列表达式中使用的函数
-2. 对照确定性函数支持列表
-3. 区分默认值和生成列的使用场景
-
-**解决方案**:
-
-```sql
--- 错误：在生成列中使用非确定性函数
-created_at TIMESTAMP GENERATED ALWAYS AS (current_timestamp())
-
--- 正确：使用默认值
-created_at TIMESTAMP DEFAULT current_timestamp()
-
--- 正确：生成列使用确定性函数
-date_part STRING GENERATED ALWAYS AS (date_format(some_timestamp, 'yyyy-MM-dd'))
-```
-
-#### 错误4：分区类型不支持
-
-**错误信息**:
-
-```

-
-**诊断步骤**:
-
-1. 检查分区列的数据类型
-2. 对照支持分区的数据类型列表
-3. 评估是否可以使用生成列转换
-
-**解决方案**:
-
-```sql
--- 错误：直接使用TIMESTAMP分区
-PARTITIONED BY (created_time)
-
--- 正确：使用生成列转换
-CREATE TABLE correct_partition (
-    created_time TIMESTAMP,
-    date_part STRING GENERATED ALWAYS AS (date_format(created_time, 'yyyy-MM-dd'))
-) PARTITIONED BY (date_part);
-```

-#### 错误5：动态分区数量超限
-
-**错误信息**:
-
-```
-The count of dynamic partitions exceeds the maximum number 2048
-```
-
-**原因分析**: 单次插入操作涉及的动态分区数量超过2048个
-
-**诊断步骤**:
-
-1. 分析源数据的分区键分布
-2. 统计涉及的不同分区值数量
-3. 评估数据插入策略
-
-**解决方案**:
-
-```sql
--- 查询源数据的分区分布
-SELECT partition_column, COUNT(*) 
-FROM source_table 
-GROUP BY partition_column 
-ORDER BY COUNT(*) DESC;
-
--- 分批插入数据
-INSERT INTO target_table 
-SELECT * FROM source_table 
-WHERE date_column BETWEEN '2024-01-01' AND '2024-01-31';
-```
-
-#### 错误6：ARRAY类型列索引指定analyzer
-
-**错误信息**:
-
-```
-invalid.inverted.index.analyzer.type, array<string>
-```
-
-**原因分析**: 在ARRAY类型列上创建倒排索引时指定了analyzer参数
-
-**诊断步骤**:
-
-1. 检查CREATE INVERTED INDEX语句
-2. 确认索引列是否为ARRAY类型
-3. 检查是否包含analyzer参数
-
-**解决方案**:
-
-```sql
--- 错误：ARRAY类型指定analyzer
-CREATE INVERTED INDEX tags_analyzer_idx 
-ON TABLE array_column_table(tags)
-PROPERTIES ('analyzer' = 'keyword');
-
--- 正确：不指定analyzer
-CREATE INVERTED INDEX tags_idx 
-ON TABLE array_column_table(tags);
-```
-
-### 性能问题诊断
-
-#### 查询性能慢
-
-**可能原因和解决方案**:
-
-1. **分区剪枝未生效**
-   ```sql
-   -- 检查查询是否使用分区列
-   EXPLAIN SELECT * FROM table WHERE partition_column = 'value';
-
-   -- 确保WHERE条件包含分区列
-   WHERE date_partition = '2024-01-15'  -- 而不是 WHERE original_date = '2024-01-15'
-   ```
-
-2. **缺少合适的索引**
-   ```sql
-   -- 为高频查询列创建索引
-   CREATE BLOOMFILTER INDEX table_column_idx ON TABLE table_name(column_name);
-   ```
-
-3. **分桶策略不当**
-   ```sql
-   -- 检查分桶列的基数分布
-   SELECT bucket_column, COUNT(*) 
-   FROM table_name 
-   GROUP BY bucket_column 
-   ORDER BY COUNT(*) DESC;
-
-   -- 选择高基数、分布均匀的列作为分桶键
-   ```
-
-#### 写入性能差
-
-**可能原因和解决方案**:
-
-1. **分桶数量设置不当**
-   ```sql
-   -- 小表使用过多分桶 → 减少分桶数
-   -- 大表使用过少分桶 → 增加分桶数
-   ```
-
-2. **数据倾斜问题**
-   ```sql
-   -- 选择更均匀分布的分桶键
-   HASH CLUSTERED BY (more_uniform_column)
-   ```
-
-3. **过多索引维护开销**
-   ```sql
-   -- 删除不必要的索引
-   DROP INDEX unnecessary_index_name;
-   ```

-# LangChain 框架简介
-
-LangChain 是一款开源的框架，旨在帮助开发人员构建基于大型语言模型（LLM）的应用程序。它通过以下几个核心优势，让开发过程变得更加高效和便捷：
-
-1. 数据源集成：LangChain 可以无缝地将 LLM 与实时数据库、API 等多源数据进行整合，确保生成的内容既准确又具有上下文性。
-2. 组件化流程设计：通过灵活配置任务链，将预处理、模型调用和后处理步骤清晰地串联起来，提高执行效率。
-3. 简化大模型访问：提供简洁的接口，降低使用 LLM 进行技术开发的门槛，快速实现复杂的 NLP 功能。
-4. 高度扩展定制：具备良好的可扩展性，能够满足不同业务场景的需求，帮助开发者充分发挥 LLM 的潜力。
-
-# 基本开发流程
-
-本节将通过一个示例，展示如何结合使用 LangChain 和 clickzetta-sqlalchemy 来实现一个简单的查询 Lakehouse 并展示结果的应用。
-
-## 环境准备
-
-要使用 LangChain 与不同的数据源进行对接，您需要在 Python 环境中安装 `clickzetta-sqlalchemy`。安装方法如下：
-
-```shell
-pip install langchain clickzetta-sqlalchemy
-```
-
-## 示例代码
-
-首先，创建一个名为 `demo.py` 的文件，并编辑代码如下：
-
-```python
-from langchain_community.utilities import SQLDatabase
-import streamlit as st
-
-# 从 Streamlit 密钥管理器获取 Lakehouse 认证信息
-username = st.secrets.lakehouse.username
-password = st.secrets.lakehouse.password
-account = st.secrets.lakehouse.account
-endpoint = st.secrets.lakehouse.endpoint
-workspace = st.secrets.lakehouse.workspace
-schema = st.secrets.lakehouse.schema
-virtualcluster = st.secrets.lakehouse.virtualcluster
-
-# 创建连接字符串
-CONNECTION_STRING = (
-    f"clickzetta://{username}:{password}"
-    f"@{account}.{endpoint}/{workspace}?schema={schema}&virtualcluster={virtualcluster}"
-)
-
-# 从连接字符串创建 SQLDatabase 实例
-db = SQLDatabase.from_uri(CONNECTION_STRING, schema=schema)
-```
-
-接下来，执行查询并返回查询结果：
-
-```python
-# 执行查询
-result = db.run("SELECT * FROM Artist LIMIT 12;", fetch="cursor")
-# 打印结果类型
-print(type(result))
-# 展示查询结果
-pprint(list(result.mappings()))
-```
-
-为了绑定查询参数，请使用可选`parameters` 参数。
-
-```
-result = db.run("SELECT * FROM Artist WHERE Name LIKE :search;",parameters={"search": "p%"},fetch="cursor",)
-pprint(list(result.mappings()))
-```
-

-## LEFT 函数
-
-Lakehouse 中的 LEFT 函数用于从给定的字符串左侧提取指定数量的字符。需要注意的是，字符长度的单位是 utf8 字符，这意味着一个中文字符将被视为一个长度单位。
-
-### 函数语法
-
-LEFT 函数的语法格式如下：
-
-```Plaintext
-LEFT(str, len)
-```
-
-- `str`：待提取字符的字符串。该参数接受 VARCHAR 类型的数据。
-- `len`：需要从字符串左侧提取的字符数量。该参数应为正整数。
-
-### 返回值
-
-LEFT 函数返回一个字符串，包含从输入字符串左侧提取的指定数量的字符。返回值的数据类型为 VARCHAR。
-
-### 使用示例
-
-以下为 LEFT 函数的几个使用示例：
-
-#### 示例 1：
-
-```SQL
-SELECT LEFT('Hello, welcome to Lakehouse', 5);
-```
-
-此查询将返回字符串 'Hello, welcome to Lakehouse' 左侧的前 5 个字符，即 'Hello'。
-
-#### 示例 2：
-
-```SQL
-SELECT LEFT('Lakehouse，一个强大的实时数据仓库。', 9);
-```
-
-此查询将返回字符串 'Lakehouse，一个强大的实时数据仓库。' 左侧的前 9 个字符，即 'Lakehouse'。
-
-#### 示例 3：
-
-```SQL
-SELECT LEFT('The quick brown fox jumps over the lazy dog', 9);
-```
-
-此查询将返回字符串 'The quick brown fox jumps over the lazy dog' 左侧的前 9 个字符，即 'The quick'。
-
-### 注意事项
-
-- 确保 `len` 参数为正整数，否则函数将返回错误。
-- 如果 `len` 参数大于输入字符串的长度，LEFT 函数将返回整个输入字符串。

-# like运算符使用指南
-
-LIKE 运算符是一种在 SQL 查询语句中用于字符串匹配的工具，它可以帮助您判断一个字符串是否符合特定的模式。LIKE 运算符在进行匹配时是**区分大小写**的，这意味着 'A' 和 'a' 会被视为不同的字符。
-
-## 语法
-
-LIKE 运算符的基本语法如下：
-
-```SQL
-str [ NOT ] LIKE pattern
-```
-
-其中，`str` 是要匹配的字符串表达式，`pattern` 是要匹配的模式表达式。您还可以使用 `NOT` 关键字来反转匹配条件。
-
-此外，LIKE 运算符还支持与 `ANY`、`SOME` 或 `ALL` 关键字结合使用，以便在多个模式中进行匹配。当使用 `ALL` 时，`str` 必须匹配所有给定的模式；而使用 `ANY` 或 `SOME` 时，`str` 只需匹配至少一个模式。
-
-### 模式中的通配符
-
-LIKE 运算符的模式中包含以下两种特殊字符，用于表示通配匹配：
-
-* `_`：匹配任意单个字符（类似于 POSIX 正则表达式中的 `.`）。
-* `%`：匹配任意数量的字符（类似于 POSIX 正则表达式中的 `.*`）。
-
-## 使用示例
-
-假设我们有一个名为 `students` 的表，其中包含学生的姓名和班级信息，如下所示：
-
-```SQL
-CREATE TABLE students (
-  name STRING,
-  class STRING
-);
-
-INSERT INTO students (name, class) VALUES
-  ('Alice', 'A'),
-  ('Bob', 'B'),
-  ('Carol', 'A'),
-  ('David', 'C');
-```
-
-以下是一些使用 LIKE 运算符的查询示例，以及它们的输出结果：
-
-1.  查询班级中包含字母 "A" 的学生（区分大小写）：
-
-```SQL
-SELECT name, class
-FROM students
-WHERE class LIKE '%A%';
-
-+-------+-------+
-| name  | class |
-+-------+-------+
-| Alice | A     |
-| Carol | A     |
-+-------+-------+
-```
-
-2.  查询姓名以 "A" 开头的学生（区分大小写）：
-
-```SQL
-SELECT name, class
-FROM students
-WHERE name LIKE 'A%';
-
-+-------+-------+
-| name  | class |
-+-------+-------+
-| Alice | A     |
-+-------+-------+
-```
-
-3.  查询姓名以 "B" 或 "C" 开头的学生：
-
-```SQL
-SELECT name, class
-FROM students
-WHERE name LIKE ANY ('B%', 'C%');
-
-+-------+-------+
-| name  | class |
-+-------+-------+
-| Bob   | B     |
-| Carol | A     |
-+-------+-------+
-```
-
-4.  查询姓名中同时包含字母 "a" 和 "l" 的学生：
-
-```SQL
-SELECT name, class
-FROM students
-WHERE name LIKE ALL ('%a%', '%l%');
-
-+-------+-------+
-| name  | class |
-+-------+-------+
-| Carol | A     |
-+-------+-------+
-```
-
-5.  查询姓名不以 "D" 开头的学生：
-
-```SQL
-SELECT name, class
-FROM students
-WHERE name NOT LIKE 'D%';
-
-+-------+-------+
-| name  | class |
-+-------+-------+
-| Alice | A     |
-| Bob   | B     |
-| Carol | A     |
-+-------+-------+
-```

-# 功能
-
-`SHOW PARTITIONS` 是一个在 SQL 中用于显示指定表的分区信息的命令。分区表是一种在数据仓库中常见的数据组织方式，它通过将数据分散存储在不同的分区中来优化查询性能和管理效率。使用 `SHOW PARTITIONS` 可以快速查看表的分区结构和每个分区的详细信息。
-
-# 使用限制
-
-* 目前使用 [实时sdk](java_reference/realtime-upload.md) 写入的分区无法立即查看，需要等待实时写入的数据提交后才能查看分区大小。
-
-# 语法
-
-```SQL
-SHOW PARTITIONS [EXTENDED] table_name [ PARTITION ( partition_col_name = partition_col_val [ , ... ] ) ]
-[WHERE <expr>]
-```
-
-## 参数说明
-
-* **EXTENDED**: 添加该关键字可以查看分区的文件数量、分区大小、分区条数和修改时间。
-* **table\_name**: 需要查询分区信息的表名，支持表、动态表、物化视图。
-* **PARTITION ( partition\_col\_name = partition\_col\_val** \[ , ... ] )**: 可选参数，用于指定要查看的分区的特定条件。通过指定分区键的值，可以过滤出特定的分区信息。
-* **WHERE \<expr>**: 可选参数，可以根据显示的字段进行过滤。支持根据 total\_rows、bytes、total\_files、created\_time 进行过滤。expr 支持 =、!=、>、< 、>= 、<=、 is null 、is not null、 between ...and、or、not 、<> 、IN。
-
-## 使用场景
-
-* **查看分区结构**: 了解表的分区策略和当前的分区情况，查看分区大小和修改时间。
-* **数据管理**: 在进行数据导入、导出或维护时，了解分区信息有助于更高效地管理数据。
-
-## 示例

-# 导入本地数据
-
-本文档详细介绍了如何将本地数据导入Lakehouse平台。目前，Lakehouse支持三种主要的本地数据导入模式：
-
-1. 使用PUT命令上传本地文件，导入到Lakehouse中
-2. **通过Lakehouse Studio页面可视化上传**：适用于小数据量的文件上传，提供用户友好的界面和简化的上传流程。
-3. **使用JDBC客户端上传数据**：适合技术用户，尤其是需要批量处理小数据量文件的用户，支持快速处理CSV文件和脚本化、自动化操作。（在 JDBC 2.0.0 版本该功能已下线，推荐您使用 PUT 命令上传）
-
-
-## 应用场景
-
-* **PUT命令上传文件**：适用于源文件上传，并且需要使用 SQL 进行转换的场景。推荐在上传过程中使用 SQL 来转换或处理异常数据。支持 CSV、PARQUET、ORC 格式。
-* **Lakehouse Studio页面**：适合需要上传小数据量文件的用户，支持CSV、PARQUET、AVRO、ORC、TEXT格式，但不支持压缩文件格式。建议先在本地解压缩再上传。
-* **JDBC客户端**：仅支持 CSV 文件格式，不支持压缩文件，适合快速处理和自动化数据导入任务。在 JDBC 2.0.0 之后的版本中，本地 COPY 命令已被弃用。我们建议您使用 PUT 命令将数据上传到 Volume 中，然后使用服务器端的 COPY 命令进行导入。
-
-# 使用案例
-
-## 使用PUT命令上传数据
-
-Lakehouse目前内置了一些[Internal Volume](internal_volume.md)可以存储文件，Internal Volume目前支持USER VOLUME和TABLE VOLUME两种对象类型。我们通过 PUT 命令将文件上传到 Internal Volume，然后使用 COPY 命令将 Volume 数据导入到表中。
-
-**前置条件**
-
-* 已安装[命令行工具](connect-with-cli.md)。或者，您也可以使用开源工具如 DBeaver、SQL Workbench/J 来执行该命令。
-* 对目标表具有INSERT权限。
-
-1. 在命令行中执行PUT命令将文件上传至TABLE VOLUME
-
-```SQL
---上传文件至user volume根目录
-PUT '/Users/Downloads/data.csv' TO TABLE VOLUME t_copy_from_volume FILE 'data.csv';
-```
-
-2. 使用[COPY INTO](copy-into-table.md)命令导入文件数据至目标表
-
-```SQL
-COPY INTO t_copy_from_volume FROM TABLE VOLUME t_copy_from_volume(id int, name string)  USING csv  
-OPTIONS(
-        'header'='true',
-        'lineSep'='\n'
-)
-FILES ('data.csv')
---删除volume中的文件，节省存储
-PURGE=TRUE;
-;
-```
-
-## 使用Lakehouse Studio页面上传
-
-## 使用限制
-
-* **文件格式限制**：不支持复杂类型如ARRAY、MAP、STRUCT、JSON、INTERVAL。对于复杂类型数据，建议使用STRING类型映射，并通过Lakehouse SQL函数进行转化。
-* **文件大小限制**：Lakehouse Studio页面和Jdbc客户端支持的单个文件最大为2GB。
-* **COPY命令限制**：不支持在Studio页面上使用COPY命令上传本地文件。该命令需要指定本地文件路径，而Studio页面无法访问本地文件系统。
-在数据管理中，顶部区域还提供“上传”功能，支持将本地文件上传至云器 Lakehouse 平台。
-
-  ![](.topwrite/assets/image_1736307536920.png =640)
-
-点击“上传”按钮，您可以轻松将数据从本地文件加载到云器 Lakehouse 平台。支持 CSV 和 TXT 两种格式，上传文件的总大小不能超过 2 GB。
-
-![](.topwrite/assets/image_1714292021540.png =360)
-
-**格式说明**
-
-* **遇到错误**：当数据行中遇到异常数据等错误场景时的处理方式。
-
-* **列分隔符**：列之间的分隔符，只允许使用单个字符。对于 CSV 文件，默认为逗号。
-
-* **换行符**：设定换行符的处理方式，Windows 系统为 \r\n，Linux、macOS 系统为 \n。
-
-* **忽略表头**：指是否忽略上传文件中的表头。
-
-* **空值表示**：指定文件中空值（NULL）的表达方式。
-
-* **集群**：需要选择集群后，才能进行数据上传。
-
-* **数据写入方式**：
-
-  * **追加写入**：不对历史数据做处理，直接追加写入。
-  * **先清空后写入**：先清空表中的历史数据，然后写入新数据。

-# 批量从对象存储导入数据
-
-本文档详细介绍了如何使用 Lakehouse 的 SQL 引擎从对象存储中导入数据。目前，Lakehouse 支持两种主要的数据导入模式：
-
-1.  **使用 Volume 导入**：通过创建和管理对象存储上的 Volume 来导入数据。
-2.  **使用 COPY 命令导入**：利用 SQL 的 COPY 命令直接从对象存储中加载数据。
-
-# 参考文档
-
-[数据湖查询](structure_data_analysis.md)
-
-[COPY INTO](copy-into-table.md)
-
-# 应用场景
-
-*   利用 SQL 引擎的性能优势快速读取大量数据，高效处理大规模数据集。
-*   支持在数据导入过程中使用 SQL 进行数据转换，实现 ETL（Extract, Transform, Load）流程。
-*   建议在导入数据时选择通用型计算集群（GENERAL PURPOSE VIRTUAL CLUSTER），以适应批量作业和数据加载的需求。
-
-# 使用限制
-
-*   **对象存储支持**：目前 Volume 的目标对象存储仅支持阿里云 OSS 和腾讯云 COS。
-*   **费用说明**：从外部 Volume 下载文件可能会产生云账号的对象存储下载费用，具体费用请参考相应云服务商的计费说明。如果 Lakehouse 与对象存储位于同一地域，使用内网 Endpoint 可以避免额外费用。
-*   **跨云导入**：目前不支持跨云服务商导入数据（未来版本将支持）。
-
-# 使用案例
-
-## 使用Volume从OSS读取CSV数据导入
-
-本文详细介绍了如何利用 Lakehouse 的 Volume 和 COPY 命令从阿里云对象存储服务（OSS）导入[巴西电子商务](https://www.kaggle.com/datasets/olistbr/brazilian-ecommerce?select=olist_customers_dataset.csv)的公共数据集。或者，您也可以直接通过[链接](https://czsampledata.oss-cn-shanghai.aliyuncs.com/eCommerce/BrazilianECommerce/olist_customers_dataset.csv?Expires=1713960305\&OSSAccessKeyId=TMP.3Kj9FumEnKg87NyAXLcgdBykW427fGRqHzTyiLfNtki6Vagmg1zMHEfVcqov1PXETvKM7DKauBXyah4YNWhfdgHNufoq2j\&Signature=afXWkoRTi%2BercYhvlsPKdrpv0Fg%3D\&x-oss-request-payer=requester)下载本次案例的数据集，然后上传到 OSS 中。该过程包括数据表的创建、对象存储连接的配置、Volume 的管理以及数据的加载和状态检查。

-CREATE STORAGE CONNECTION  braziliandata_conn
-    TYPE oss
-    ENDPOINT = 'oss-cn-shanghai-internal.aliyuncs.com'
-    access_id = 'xxxx'
-    access_key = 'xxxx'
-    comments = 'OSS public endpoint';
- --查看创建的conneciton
- SHOW CONNECTIONS;
---创建Volume用于管理对象存储上面的数据
-CREATE EXTERNAL VOLUME braziliandata_csv
-    location 'oss://yourbucketname/eCommerce/BrazilianECommerce/'
-    using connection braziliandata_conn
-    directory = (
-        enable=true,
-        auto_refresh=true
-    );
-  SHOW VOLUMES;
-```
-
-### **使用Volume加载数据**
-
-*   指定 Volume 中需要读取的文件，可以在 `files` 参数中指定。
-*   在 `options` 中可以设置 CSV 文件的参数，如分隔符等，具体设置可参考文档。

-要使用 Map Join，只需在查询语句中添加一个提示 `/*+ MAPJOIN (table) */`，其中 `table` 表示需要加载到内存中的小表名称。例如：
-
-```SQL
-SELECT /*+ MAPJOIN (t2) */ * FROM table1 t1
-JOIN table2 t2
-ON (t1.emp_id = t2.emp_id);
-```
-
-在这个例子中，`table2` 是一个小表，通过 Map Join 的方式，它会被加载到内存中，并与 `table1` 在 Map 阶段完成 JOIN 操作。
-
-## 优点
-
-Map Join 具有以下优点：
-
-1. 省去了 Shuffle 阶段，减少了网络传输和磁盘 I/O 的开销。
-2. 避免了数据倾斜问题，因为不需要按照 JOIN 列进行数据分发。
-3. 提高了查询执行速度，尤其对于小表 JOIN 大表的场景。
-
-## 缺点
-
-Map Join 存在以下限制：
-
-1. 小表必须能够完全加载到内存中，否则可能导致内存溢出或 Map Join 失败。目前 Lakehouse 限制小表大小为 1GB。
-2. Map Join 仅适用于小表与大表的 JOIN 操作，对于大表与大表的 JOIN 场景，则无法发挥优势。
-
-## 使用示例
-
-以下是一些 Map Join 的使用示例：
-
-### 示例1：员工信息与部门信息的关联查询
-
-```SQL
-SELECT /*+ MAPJOIN (dept) */ * FROM employees emp
-JOIN departments dept
-ON (emp.dept_id = dept.dept_id);
-```
-
-### 示例2：订单信息与客户信息的关联查询
-
-```SQL
-SELECT /*+ MAPJOIN (customer) */ * FROM orders order_
-JOIN customers customer
-ON (order_.customer_id = customer.customer_id);
-```
-
-### 示例3：销售记录与员工信息的关联查询
-
-```SQL
-SELECT /*+ MAPJOIN (employee) */ * FROM sales sales_
-JOIN employees employee
-ON (sales_.employee_id = employee.employee_id);
-```
-
-通过以上示例，您可以看到 Map Join 在不同场景下的应用。在实际使用中，请确保小表能够完全加载到内存中，以充分发挥 Map Join 的优势。

-# 元数据对象及权限（Privileges）
-
-## 权限定义
-
-访问控制权限的授予决定了用户可以对特定对象执行指定操作。对于云器Lakehouse中的每个元数据对象，都有一组可以授予的权限。云器Lakehouse中的所有元数据对象及其拥有的权限点，详见 权限点 文档。
-
-元数据对象有三种表达方式：
-
-1）以对象类型加对象名称，表达已被创建的对象。例如：table mytable（名称为mytable的表） 或 vcluster myvcluster（名称为myvcluster的计算集群）；
-
-2）以关键字 ALL 加对象类别，表达现有和未来所有该类型的对象。例如：ALL tables in schema my\_schema （名称为my\_schema的schema下的所有table类型对象）；
-
-3）以关键字ALL 加关键在 OBJECTS表达现有和未来的所有类型的所有对象，例如：ALL OBJECTS in workspace my\_workspace（名称为my\_workspace的工作空间下所有的对象）。
-
-权限点有两种表达方式：
-
-1）以具体权限点表达，例如：select，read metadata，update 等；
-
-2）以关键字 ALL 加关键字 PRIVILEGES，表达所有权限点，例如：ALL PRIVILEGES on table mytable（mytable表的所有权限点）。
-
-在使用SQL语句进行权限管理时，使用 GRANT <权限点> 和 REVOKE <权限点> 命令。在 GRANT <权限点> 语句末尾加上 WITH GRANT OPTION，表示在授予该权限点的同时，将允许被授予者将该权限点再授予其他角色或用户。
-
-## 元数据对象
-
-Lakehouse中的元数据对象及其父级对象如下表所示：
-
-| **元数据对象**         | **父级对象**  |
-| ----------------- | --------- |
-| workspace         | instance  |
-| share             | instance  |
-| network policy    | instance  |
-| schema            | workspace |
-| virtual cluster   | workspace |
-| connection        | workspace |
-| table             | schema    |
-| view              | schema    |
-| materialized view | schema    |
-| dynamic table     | schema    |
-| table stream      | schema    |
-| volume            | schema    |
-| index             | schema    |
-| function          | schema    |
-| job               | schema    |
-
-元数据对象均可以通过SQL进行授权。工作空间内的对象可在Web端，在“管理”-“安全”-“权限”中操作授权。
-
-### ALL 对象
-
-ALL 对象是一种特殊的元数据对象，表达一类对象下**当前**和**未来**的所有个体。例如：all tables表达当前和未来的所有table；all vclusters表达当前和未来的所有计算集群。
-
-ALL 对象在使用时，需要和关键字“IN”一起使用，以明确 ALL 对象描述的范围，关键字“IN”之后跟随的是 ALL 对象的父级对象。例如：all tables in schema my\_schema; all vclusters in workspace my\_workspace。
-
-ALL 对象的一种特殊用法是用于指代某父级对象下的所有自级对象，例如：all objects in schema my\_schema，表达my\_schema下的所有类型对象，包括table、view、functions等。
-
-注意：尽管ALL对象可以提升授权操作的效率，但请谨慎使用all objects的方式授权。仅在确认all objects指代的范围符合授权预期时，再使用all objects进行指代，避免授权范围超出预期。
-
-## 业务对象
-
-除元数据对象外，在数据开发、数据治理过程中，产生了业务对象，如下表所示：
-
-| **业务对象**           | **业务类别**              |
-| ------------------ | --------------------- |
-| 脚本（Script）         | 数据开发（development）     |
-| 任务和实例（Task）        | 监控规则（monitor rules）   |
-|                    | 通知策略（announce policy） |
-| 数据质量（Data Quality） | 质量规则（DQC rule）        |
-
-业务对象不可通过SQL进行授权。用户通过被授予包含业务对象权限的预置角色来获取相关权限。暂不支持对业务对象的细粒度授权。

-| all privileges | 包含job对象的所有权限 | 不可用于授权。job执行者默认拥有此权限。                            |
-
-### ALL 权限点
-
-ALL 权限点是各类元数据对象上均存在的一个权限点，表达该对象的所有权限点。ALL权限点是一个**独立**的权限点，与其他权限点并非指代关系。因此授予ALL权限点不会覆盖授予其他权限点，解除ALL权限点也不会解除其他权限点。
-
-例如：对user my\_user 先后授予了example\_table的select和ALL权限点。则此时my\_user用户由于被授予了ALL权限点，可以对example\_table执行所有操作；在查询my\_user用户对example\_table的权限时，显示同时拥有的select和all权限点的授权。当对my\_user用户解除ALL权限点的授权时，my\_user用户仍具备对example\_table进行select操作的权限。
-
-使用ALL权限点可以快速完成对一个对象所有权限的授予，例如：

-
-### 基本用法
-
-#### 1. 查看所有表
-
-```sql
--- 显示当前Schema中的所有表对象
-SHOW TABLES;
-
--- 限制返回数量
-SHOW TABLES LIMIT 10;
-```
-
-#### 2. 指定Schema查询
-
-```sql
--- 查看特定Schema中的表
-SHOW TABLES IN production_schema;
-SHOW TABLES IN information_schema;
-
--- 组合Schema和限制条件
-SHOW TABLES IN data_warehouse LIMIT 20;
-```
-
-#### 3. 模式匹配查询
-
-```sql
--- 查找以特定前缀开头的表
-SHOW TABLES LIKE 'fact_%';
-SHOW TABLES LIKE 'dim_%';
-
--- 查找包含特定字符串的表
-SHOW TABLES LIKE '%customer%';
-SHOW TABLES LIKE '%_temp';
-
--- 单字符通配符
-SHOW TABLES LIKE 'table_?';
-```
-
-### 高级过滤条件
-
-#### 1. 按表类型过滤
-
-```sql
--- 只显示普通表（排除视图）
-SHOW TABLES WHERE is_view = false;
-
--- 只显示视图
-SHOW TABLES WHERE is_view = true;
-
--- 只显示物化视图
-SHOW TABLES WHERE is_materialized_view = true;
-
--- 只显示动态表
-SHOW TABLES WHERE is_dynamic = true;
-
--- 只显示外部表
-SHOW TABLES WHERE is_external = true;
-```
-
-#### 2. 组合条件查询
-
-```sql
--- 查找非外部的普通表
-SHOW TABLES WHERE is_view = false AND is_external = false;
-
--- 查找所有类型的视图（包括物化视图）
-SHOW TABLES WHERE is_view = true OR is_materialized_view = true;
-
--- 在指定Schema中查找动态表
-SHOW TABLES IN analytics_schema WHERE is_dynamic = true;
-
--- 查找内部的数据表（排除视图和外部表）
-SHOW TABLES WHERE is_view = false 
-  AND is_external = false 
-  AND is_materialized_view = false;
-```
-
-#### 3. 复杂业务查询
-
-```sql
--- 数据治理：查找所有需要监控的核心表
-SHOW TABLES WHERE is_external = false 
-  AND is_view = false 
-  AND table_name NOT LIKE '%_temp%'
-  AND table_name NOT LIKE '%_staging%';
-
--- 性能分析：查找所有可能影响性能的动态表
-SHOW TABLES WHERE is_dynamic = true;
-
--- 架构审计：查找所有外部依赖
-SHOW TABLES WHERE is_external = true;
-```
-
-### 语法限制和注意事项
-
-#### ✅ 支持的组合
-
-* `IN schema_name` + `WHERE condition`
-* `IN schema_name` + `LIMIT n`
-* `WHERE condition` + `LIMIT n`
-* `LIKE pattern` (单独使用)
-
-#### ❌ 不支持的组合
-
-```sql
--- ❌ LIKE和WHERE不能同时使用
--- SHOW TABLES LIKE 'test%' WHERE is_dynamic=true;
-
--- 解决方案：使用WHERE条件中的LIKE操作
-SELECT schema_name, table_name, is_dynamic 
-FROM (SHOW TABLES) 
-WHERE table_name LIKE 'test%' AND is_dynamic = true;
-```
-
-### 实际应用场景
-
-#### 场景1：数据架构分析
-
-```sql
--- 1. 了解Schema中的表分布
-SHOW TABLES IN production_schema;
-
--- 2. 分析表类型分布
-SELECT 
-  CASE 
-    WHEN is_view THEN 'VIEW'
-    WHEN is_materialized_view THEN 'MATERIALIZED_VIEW'
-    WHEN is_dynamic THEN 'DYNAMIC_TABLE'
-    WHEN is_external THEN 'EXTERNAL_TABLE'
-    ELSE 'REGULAR_TABLE'
-  END as table_type,
-  COUNT(*) as count
-FROM (SHOW TABLES)
-GROUP BY table_type;
-```
-
-#### 场景2：数据清理和维护
-
-```sql
--- 查找临时表和测试表
-SHOW TABLES WHERE table_name LIKE '%temp%' 
-  OR table_name LIKE '%test%' 
-  OR table_name LIKE '%staging%';
-
--- 查找可能的备份表
-SHOW TABLES WHERE table_name LIKE '%_backup%' 
-  OR table_name LIKE '%_bak%'
-  OR table_name LIKE '%_old%';
-```
-
-#### 场景3：权限和安全审计
-
-```sql
--- 查找所有外部数据源
-SHOW TABLES WHERE is_external = true;
-
--- 查找需要特别关注的动态表
-SHOW TABLES WHERE is_dynamic = true;
-
--- 按Schema分析表的分布
-SELECT schema_name, COUNT(*) as table_count
-FROM (SHOW TABLES)
-GROUP BY schema_name
-ORDER BY table_count DESC;
-```
-
-#### 场景4：开发环境管理
-
-```sql
--- 开发环境：查找个人开发表
-SHOW TABLES LIKE '%_dev_%';
-SHOW TABLES LIKE 'tmp_%';
-
--- 生产环境：查找核心业务表
-SHOW TABLES IN production 
-WHERE is_view = false 
-  AND is_external = false
-  AND table_name LIKE 'fact_%' 
-   OR table_name LIKE 'dim_%';
-```
-
-### 性能优化建议
-
-#### 1. 使用精确过滤
-
-```sql
--- ✅ 好的做法：使用精确条件
-SHOW TABLES IN specific_schema WHERE is_dynamic = true;
-
--- ❌ 避免：查询所有后过滤
--- SELECT * FROM (SHOW TABLES) WHERE schema_name = 'specific_schema';
-```
-
-#### 2. 合理使用LIMIT
-
-```sql
--- 在大型环境中总是使用LIMIT
-SHOW TABLES LIMIT 50;
-SHOW TABLES IN large_schema LIMIT 100;
-```
-
-#### 3. 组合查询策略
-
-```sql
--- 第一步：快速概览
-SHOW TABLES IN target_schema LIMIT 10;
-
--- 第二步：精确查找
-SHOW TABLES IN target_schema WHERE is_dynamic = true;
-
--- 第三步：详细分析
-SELECT table_name, is_view, is_dynamic, is_external
-FROM (SHOW TABLES IN target_schema)
-WHERE table_name LIKE '%customer%';
-```
-
-### 与其他命令的配合使用
-
-```sql
--- 结合DESC命令进行深度分析
-SELECT table_name FROM (SHOW TABLES WHERE is_dynamic = true);
--- 然后对每个动态表执行：DESC TABLE table_name;
-
--- 结合Information Schema获取更多信息
-SELECT t.table_name, t.is_dynamic, i.create_time, i.row_count
-FROM (SHOW TABLES WHERE is_dynamic = true) t
-LEFT JOIN information_schema.tables i 
-  ON t.table_name = i.table_name 
-  AND t.schema_name = i.table_schema;
-```
-
-### SHOW TABLES与其他SHOW命令的功能对比

-SELECT current_workspace(), current_schema(), current_user(), current_vcluster();
-
--- 2. 检查基本权限
-SHOW GRANTS;
-
--- 3. 验证对象存在性
-SHOW SCHEMAS;
-SHOW TABLES LIMIT 10;
-
--- 4. 测试简单查询
-SHOW TABLES LIMIT 5;
-```
-
-## 结合Information Schema的深度分析
-
-### 元数据深度挖掘
-
-```sql
--- 使用SHOW命令快速定位
-SHOW TABLES LIKE '%fact%';
-
--- 结合Information Schema深度分析
-SELECT table_name, table_type, create_time, row_count
-FROM information_schema.tables 
-WHERE table_name LIKE '%fact%'
-  AND table_schema = 'data_warehouse'
-ORDER BY create_time DESC;
-
--- 分析作业执行模式
-SHOW JOBS LIMIT 5;
-
-SELECT job_creator, COUNT(*) as job_count, 
-       AVG(execution_time) as avg_execution_time
-FROM information_schema.job_history 
-WHERE pt_date >= CURRENT_DATE - INTERVAL '7 DAYS'
-GROUP BY job_creator
-ORDER BY job_count DESC;
-```
-
-### 自动化监控查询
-
-```sql
--- 集群状态监控（直接查询，不创建视图）
-SELECT 
-    'VCLUSTER' as resource_type,
-    name as resource_name,
-    state as status,
-    current_vcluster_size as current_size,
-    running_jobs as active_jobs
-FROM (SHOW VCLUSTERS)
-WHERE state != 'RUNNING';
-```
-
-## 语法限制和注意事项
-
-### Information Schema列名规范
-
-```sql
--- ✅ 正确的列名
-SELECT table_schema, table_name, table_type, create_time, row_count
-FROM information_schema.tables;
-
--- ❌ 错误的列名
--- SELECT schema_name, created_time FROM information_schema.tables;
-```
-
-### SHOW命令在视图中的限制
-
-* ✅ **支持**：直接在FROM子句中使用SHOW命令
-* ❌ **不支持**：创建包含SHOW命令的视图后进行查询
-
-```sql
--- ✅ 支持的用法
-SELECT name, state FROM (SHOW VCLUSTERS);
-
--- ❌ 不推荐的用法
--- CREATE VIEW cluster_view AS SELECT * FROM (SHOW VCLUSTERS);
--- SELECT * FROM cluster_view;  -- 查询会失败
-```
-
-### 数据类型处理
-
-```sql
--- ✅ execution_time已经是double类型，无需转换
-SELECT AVG(execution_time) FROM information_schema.job_history;
-
--- ❌ 不必要的类型转换
--- SELECT AVG(CAST(execution_time AS DOUBLE)) FROM information_schema.job_history;
-```
-
-## 最佳实践总结
-
-### 1. 日常运维检查清单
-
-**每日检查**
-
-* `SHOW VCLUSTERS` - 检查集群状态
-* `SHOW JOBS LIMIT 20` - 监控作业执行
-* `SHOW CONNECTIONS` - 验证连接状态
-
-**每周检查**
-
-* `SHOW SHARES` - 审计数据共享
-* `SHOW GRANTS` - 检查权限变更
-* `SHOW USERS` - 用户管理审计
-
-### 2. 开发环境设置
-
-**新项目初始化**
-
-```sql
-SHOW SCHEMAS;                                    -- 确认可用Schema
-SHOW TABLES IN development LIMIT 20;            -- 查看开发环境表
-DESC VCLUSTER development_cluster;               -- 确认开发集群配置
-SHOW FUNCTIONS LIKE '%custom%';                  -- 查找自定义函数
-```
-
-### 3. 生产环境最佳实践

-#### 触发条件规则
-
-触发条件由监控事项、指标计算方式、阈值和触发方式组成。当前系统支持“事件监控”和“指标监控”两种类型。
-
-**基于「指标」的监控配置**
-
-![](.topwrite/assets/226957dd01/0d872f1cb6d11f16e4a48c9a6466ac9d43eb8606.png =548)
-
-针对指标监控类型，在定义好计算方式和阈值后，支持两种触发方式的配置。
-
-持续：指标一旦连续N次触碰到阈值时，则会触发监控告警。
-
-检查间隔：用户需定义在检查间隔范围内累计N次触碰到阈值后，才会触发监控告警。
-
-指标监控配置：用户可以定义计算方式和阈值，并选择触发方式。例如，配置全增量一体同步任务延迟指标，延迟时间大于等于50秒，持续3个数据点，告警频次限制为30分钟发送一次。
-
-![](.topwrite/assets/226957dd01/4f091acaf0cca77057e17882d353011c0853801e.png =600)
-
-00:40的时候，发现连续3次在阈值之上，第一次触发告警。接下来一直到01:50的时候，均处于第一次告警阶段。
-
-在告警阶段，通过告警频次判断接下来的几个时间点，结合告警频次的配置决定是否持续发送告警。告警限制为30分钟发送一次，则会在01:10、01:40两个时间点发送告警通知。
-
-从02:00开始，接下来后面的三次指标均处于阈值之下，则第一次告警恢复，不再触发告警通知。
-
-若用户的触发方式是检查监控内的累积次数。
-
-**基于「事件」的监控配置**
-
-事件监控是基于特定事件或条件发生时产生的告警。用户可以基于当前产品内的运维实例或数据质量校验规则进行监控。基于产品内当前支持的行为，当前事件监控主要分为两大类：
-
-任务运维：用户在开发场景内通过配置调度场景定义的各类周期调度任务，或者实时运行任务实例。
-
-数据质量：用户在数据质量内配置的针对表质量的各类监控。
-
-> 可以查看 [监控项口径说明文档](monitoring_item_specification.md)，来了解详细的口径说明。
-
-#### 告警事件
-
-告警事件列表展示了所有触发监控规则后的告警信息。用户可以对列表中的告警事件进行操作，如抑制或关闭。
-
-抑制：设置当前告警事件在多少分钟内不再发送消息。
-
-关闭：关闭当前告警事件，不再接收这类消息。

-
-#### 告警事件处理操作
-
-| 操作                      | 定义                 | 适用场景                | 影响范围   |
-| ----------------------- | ------------------ | ------------------- | ------ |
-| 抑制                      | 设置告警事件在指定时间内不再发送消息 | 已知问题正在处理中，暂时不需要重复告警 | 当前告警事件 |
-| 关闭                      | 关闭告警事件，停止接收此类消息    | 问题已解决或确认为误报         | 当前告警事件 |
-| 自动关闭告警  --不是在告警事件中点击处理的 | 系统检测到问题恢复后自动关闭告警   | 任务实例重跑成功、手动置成功      | 相关告警事件 |

-## 配置管理
-
-配置管理允许用户对个人信息和Webhook进行配置。
-
-### 个人配置
-
-用户可以在个人配置中修改接收告警的手机号和邮箱地址，并设置免打扰时段。

-
-### Webhook配置
-
-Webhook配置用于定义告警推送所需的Webhook渠道，当前支持飞书和钉钉。
-
-![Webhook配置界面](.topwrite/assets/226957dd01/6a8bc6fc74fb8f046f7169d91fac4169aab3b968.png =680)
-

-
-## 其它
-
-### 监控告警自动关闭
-
-对于任务实例运行失败的监控告警，在运维中心对实例进行处置后恢复成功，比如手动置成功或者重跑实例后成功等，会将对应的告警事件自动置为关闭，不需要人工去关闭。
-
-### Webhook告警的安全设置
-
-钉钉等IM，对Webhook推送告警会有一定的安全设置，通过“自定义关键词”，新增配置上“云器”这个关键词即可。

-# 多表离线同步任务
-
-## 功能概述
-
-多表离线同步任务是云器 Lakehouse Studio 提供的批量数据同步能力，支持将源端数据库的整库或多张表以周期调度的方式同步到 Lakehouse 中。与多表实时同步任务不同，多表离线同步采用定期全量同步的方式，适合数据时效性要求相对不高、数据更新具有周期性特征的场景。
-
-## 适用场景
-
-多表离线同步任务适用于以下场景：
-
-* **整库迁移**：需要将源端数据库的所有表批量同步到 Lakehouse，减少逐表配置的工作量
-* **周期性数据更新**：源端数据按固定周期（如每天、每小时）批量更新，无需保持实时同步
-* **分库分表合并**：需要将多个分库分表的数据合并同步到统一的目标表
-* **定期数据校准**：通过周期性全量同步确保目标端数据与源端保持一致
-* **资源优化**：在数据时效性要求不高的情况下，通过离线同步降低资源消耗。
-
-## 功能特性
-
-### 支持的数据源
-
-**来源端**
-* MySQL
-* PostgreSQL
-* SQL Server
-* Aurora MySQL
-* Aurora PostgreSQL
-* PolarDB MySQL
-* PolarDB PostgreSQL
-
-**目标端**
-* Lakehouse
-
-### 同步模式
-
-1. **整库镜像**：同步源端整个数据库的所有表到目标端。
-2. **多表镜像**：选择源端多张表同步到目标端，保持表结构独立。
-3. **多表合并**：将多个源表（如分库分表）合并同步到一张表或多张目标表。
-
-### 核心能力
-
-* **自动建表**：目标端表不存在时自动创建，支持主键表和非主键表，支持灵活使用参数来定制目标端表的命名。
-* **Schema变更适配**：支持源端表结构变化时自动同步到目标端（可选）。
-* **灵活的写入模式**：支持覆盖写入（overwrite）、更新写入（upsert）等多种写入模式。
-* **并发控制**：支持配置分组策略和并发度，以优化同步性能并灵活控制对源端的压力。
-* **调度管理**：基于Cron表达式的灵活调度配置，可与其他任务节点统一编排。

-
-#### 并发控制
-
-**单分组中表个数**
-
-* 在静态分组模式下手动指定
-* 控制单个分组包含的表数量
-* 默认值：4
-
-**单分组中源端最大连接数**
-
-* 限制单个分组对源端的最大并发连接数
-* 默认值：4
-
-**并发执行的分组数量**
-
-* 可同时执行的分组数量
-* 默认值：2
-
-> **性能调优建议**：并发度过高可能对源端数据库造成压力，建议根据源端数据库性能进行合理配置。
-
-#### 数据写入模式

-* **目标端权限**：任务的负责人需要具备在目标端 Lakehouse 创建表和插入数据的权限（CREATE、INSERT 权限）。
-
-### 性能考虑
-
-1. **源端压力**：合理配置并发度，避免对源端数据库造成过大压力。
-2. **初始化时间**：首次执行时需要初始化所有同步对象，可能耗时较长。
-3. **表数量限制**：建议单个任务同步的表数量控制在合理范围，过多表可能影响任务执行效率。
-
-### 数据一致性
-
-1. **覆盖写入模式**：采用覆盖写入时，每次执行会完全刷新目标表数据。
-2. **更新写入模式**：采用upsert模式时，基于主键进行增量更新。
-3. **源端数据变化**：离线同步采用定期全量同步，两次同步间隔期间的数据变化会在下次同步时体现。
-
-### Schema Evolution限制
-
-启用Schema Evolution功能时需注意：
-
-* 不支持修改主键字段（Lakehouse主键表限制）
-* 字段类型修改仅支持同类型扩展（如 int8 → int16 → int32 → int64）
-* 跨类型转换（如 int → double）不支持
-* 建议在源端Schema相对稳定时使用此功能
-
-### 最佳实践
-
-1. **任务粒度**：根据业务关联性和同步需求合理划分任务粒度
-2. **调度时间**：选择源端数据库压力较小的时间窗口执行
-3. **测试验证**：使用"运行"功能进行小批量数据测试后再正式调度
-4. **监控配置**：及时配置告警规则，确保同步异常时能快速感知
-5. **定期检查**：定期查看"表自动变更记录"，了解Schema变更情况

-### 数据库权限配置
-
-同步不同类型数据源的变更事件时，需要在相应数据源服务端配置好适当的权限才能保证数据的正常同步。尽管直接分配一个管理员或超级用户的权限足够保证任务正常运行，但通常会希望能够最小化权限需要分配给同步数据的用户的权限。各操作步骤需要的具体权限配置说明如下。
-
-#### PostgreSQL
-
-请注意，在执行赋权SQL语句时，**确保执行账号自身具备可以授权的权限，建议使用管理员账号**。为了确保任务顺利运行，**建议将下述所有场景的授权均执行一遍**。
-
-**场景：配置任务（获取元数据：schema列表、table列表、table字段列表**）
-
-所需权限：
-
-```

-  ```
-  GRANT SELECT ON ALL TABLES IN SCHEMA schema_name TO role_name;
-  ```
-
-**场景：变更数据同步，创建publication**
-
-所需权限
-
-```

-
-## 任务创建
-
-### 操作入口
-
-在任务开发界面，点击新建操作，选择“多表实时同步”任务类型。
-
-![](.topwrite/assets/image_1742960426271.png =308)
-
-### 主要步骤
-
-创建多表实时同步任务，大致分为四个步骤：
-
-1. 配置数据类型，选择从源端什么数据源同步到目标端什么数据源。
-2. 配置同步任务类型，当前区分为整库镜像实时同步、多表镜像实时同步和多表合并实时同步三种模式。
-3. 配置需要同步的对象范围，包含来源、目标。
-4. 配置一些高阶的同步规则，比如对于新增表和字段变更的处理逻辑等。
-
-### 配置数据类型
-
-配置多表实时同步任务，首先选择需要同步的来源数据和目标端数据的类型。当前支持的来源数据源类型如下：
-
-![](/.topwrite/assets/image_1762748306754.png =680)
-
-### 选择同步模式
-
-目前支持三种任务同步模式，请按需选择：
-
-* 整库镜像：用于将源端，所有库表的数据，镜像同步到目标端的场景，此种方式以数据库为粒度进行配置，会自动适配库中新增表、自动同步。
-* 多表镜像：用于将源端，选定的库表数据，镜像同步到目标端的场景。此种方式以表粒度进行配置，支持自动感知字段个数的新增和删除的变化。
-* 多表合并：用于将源端分库分表的数据合并写入同一张目标表的场景。
-
-  ![](/.topwrite/assets/image_1762757109125.png =680)
-
-#### 多表镜像
-
-**来源配置**
-
-* 选择数据源
-
-  * 对于多表镜像同步，请选择一个数据源。如果这里不展示，请新建一个数据源，详见 [数据源配置](config-datasource.md)。
-  * 请确保数据源中的账号具备足够的权限，详见下文的权限说明。
-
-* 配置读取模式
-
-  * MySQL 当前只支持 BINLOG 模式。
-  * PostgreSQL 当前只支持 WALs 模式。
-
-* 选择同步对象
-
-  * 先选择需要同步的库，再选择需要同步的表。
-  * 页面提供批量配置的功能，基于配置模板，按照格式要求填写配置文件、上传后，页面会按照文件中给定的内容来选中需要同步的对象，选中后可以按需再进行微调。请注意删除模板文件中的注释说明。
-
-* 配置槽位（slot）
-
-  * 仅PostgreSQL需要配置，槽位（slot）指PostgreSQL 的 replication slot，详见 [说明文档](https://www.postgresql.org/docs/9.4/catalog-pg-replication-slots.html)。
-  * 每个数据库都需要配置一个槽位。目前支持decoderbufs和pgoutput两种插件类型。
-  * 可以选择已存在的槽位进行使用；或者在页面页面来操作新建，在新建窗口的下方区域的创建语句，可按需修改。点击确定后进行创建。在数据源中配置的用户名必须具备创建slot的权限，否则会创建失败，详见下文的权限说明。
-  * 特别注意，不同任务不要复用同一个槽位。任务启动时，如果槽位被其它在运行中的任务占用，会启动失败。如果其它任务处在停止状态，因槽位中的数据会被共享消费使用，位点是被共享的，新任务消费的增量数据，同步到目标端的表数据可能会不全。
-
-**目标配置**
-
-目标端目前只支持写入到Lakehouse。
-
-* 目标数据源
-  * 默认是当前工作空间对应的Lakehouse数据源，不需修改。
-* 命名空间规则
-  * 当前仅支持选择特定的命名空间，后续会扩展支持按照源端进行镜像命名或者自定义命名。
-  * 按需选择特定命名空间（工作空间）即可。
-* 目标表命名规则
-  * 当前仅支持镜像来源名字，后续会扩展支持添加前缀或者自定义命名规则。
-* 计算集群
-  * 选择工作空间下可用的集群，推荐使用AP类型的集群。
-
-**预览配置**
-
-* 完成上述源端和目标端配置后，可以预览同步表和字段的映射关系。如果有需要修改，请返回上一步进行调整。
-
-**同步规则**
-
-* 同步规则中，可以配置Schema Evolution规则，来定义源端表和字段变化后的处理行为，以及选择需要处理的源端变更消息类型等。请按需配置。
-
-  ![](/.topwrite/assets/image_1762757310752.png =680)
-
-
-#### 整库镜像
-
-配置方式和多表镜像基本类似，请参考上文。最大的区别在于选择源端库表时，限制只让选择库，不可以选择具体的表。
-
-#### 多表合并
-
-**来源配置**
-
-* 选择数据源
-  * 同上，多表镜像同步类似
-* 配置读取模式
-  * 同上，多表镜像同步类似
-* 选择同步对象
-  多表合并同步，会使用“虚拟表”作为中间的过度承接，需要在配置时候指定使用什么虚拟表来承接哪些对象的数据。支持两种方式进行配置
-  * 方式一：基于规则配置，通过正则匹配进行筛选，比如选出以abc开头的所有表，在正则表达式中填写 ^abc 即可
-  * 方式二：基于文件批量配置，按照模板中格式要求填写配置文件、上传后，页面会按照文件中给定的内容来选中需要同步的对象，选中后可以按需再进行微调。请注意删除模板文件中的注释说明
-
-**目标配置**
-
-* 同上，和多表镜像同步类似
-
-**预览配置**
-
-* 同上，和多表镜像同步类似
-
-**同步规则**
-
-* 同上，和多表镜像类似
-
-### 任务高阶参数
-
-在多表实时同步任务的「参数」区域，可以设定一些高阶参数来控制同步任务的资源消耗等。
-
-> 这些参数强烈建议使用默认取值即可，非必要不修改。如需要调整，建议事先咨询服务您的技术支持人员后再修改。
-
-![](.topwrite/assets/image_1756200956528.png =680)
-
-具体可以设定的高阶参数的名称、含义和默认取值如下。这些参数默认不建议调整，如果有使用需要，建议先联系技术支持人员确认后再进行设定、更改：
-
-| 参数名称                                        | 参数含义                | 参数取值         |
-| ------------------------------------------- | ------------------- | ------------ |
-| step1.taskmanager.memory.process.size       | 增量同步任务计算进程使用的总内存大小  | 默认值：1600m    |
-| step1.taskmanager.memory.task.off-heap.size | 增量同步任务计算进程使用的堆外内存大小 | 默认值：256m     |
-| step2.taskmanager.memory.process.size       | 全量同步任务计算进程使用的总内存大小  | 默认值：2000m    |
-| lh.table.cz.common.output.file.max.size     | 全量同步写表时切分出单个文件的大小   | 默认值：33554432 |
-| lh.table.cz.common.output.enable.rotate     | 全量同步写表时是否切分文件       | 默认值：true     |
-| pod.limit.memory                            | 提交同步任务的客户端使用内存上限    | 默认值：1Gi      |
-
-### 提交
-
-点击提交按钮，可将任务提交到生产环境执行。**请注意，任务提交后默认不会自动启动，需要手动启动**。
-
-## 任务运维
-
-### 启动任务
-
-进入任务详情页，可以操作启动任务，请按需选择以下启动方式之一。任务启动后，初始化阶段，根据表的数量不同，可能会消耗几分钟或者更久的时间，请耐心等待。
-
-**启动方式**
-
-* 无状态启动（仅在任务首次启动才支持）：完整同步所有数据，先全量同步，再启动增量同步。
-* 从上次保存状态恢复（仅对停止后的任务再次启动支持）：如果上次同步被停止，会从停止的位置断点续传。
-* 自定义起始位置：从给定的位点进行同步，可以用于数据回刷。对任务中配置的所有表全统一生效。
-  * MySQL：选择指定文件启动或者指定时间启动。在页面监控区域可以获取到上次文件位置。
-  * PostgreSQL：指定LSN取值，在下文的实例监控中可以查看到最新的LSN取值。
-
-**全量同步**
-
-* 通过此配置控制在增量同步前，是否先进行全量的数据同步。请注意，如果选择不进行全量同步，停止任务后重启可以再选择全量同步。
-* 最大并发数：如果在启动任务时，选择了先进行全量数据同步，可以通过此参数来控制进行全量数据同步的并发子任务个数。同步任务会建立对应个数的JDBC连接到源端数据库。参数数值越大，理论同步速度会更快（在打满源端负载之前），但对源端的压力也会越大。
-
-### 实例监控
-
-#### 阶段监控
-
-任务启动后，会经历初始化、全量同步、增量同步三个阶段。可在实例监控区域查看这三个阶段的运行状态。

-
-### 停止任务
-
-停止任务会停止任务中正在进行的全量同步和增量同步。停止时会自动保存增量同步的位点状态。
-
-* 如果停止时表处在全量同步阶段，重启后，未完全全量同步的表，会重新进行一次全新的全量同步。
-* 如果停止时表处在增量同步阶段，重启后，默认会从同步停止的位点继续同步。
-
-### 下线任务
-
-下线任务属于高危操作，任务下线后，不会保存当前同步的位点。如果再次上线并启动任务，会重新开始同步数据。
-
-* 下线不会清理已经同步到目标端的数据，但会清理中间过程的缓存数据和位点信息。
-* 重新同步不会重新建表，全量数据同步会对于老的表进行覆盖写入，增量同步会对目标表做merge into的更新。
-
-## 已知局限
-
-* Schema Evolution，暂不支持变更字段类型、不支持自动新增表。
-
-* 多表实时同步任务中，源端不同库表中若存在主键相同的数据，同步结果会出现异常。
-
-* MySQL同步，尚不支持的字段类型：
-
-  | 字段类型 | 同步后行为 |
-  | ---- | ----- |
-  | year | 取值不对应 |
-
-* PostgreSQL同步，尚不支持的字段类型：

-# 多表实时同步任务完整指南
-
-## 功能概述
-
-多表实时同步任务，可以实现对源端库表进行全量同步和增量同步。其中增量同步，主要是基于对数据库变更消息进行处理来实现。多表实时同步任务是一个常驻任务，可达到秒级的端到端数据时效性。多表实时同步，支持两种同步类型和两种同步模式：
-
-### 两种同步类型：全量同步和增量同步
-
-* 其中全量同步为可选步骤，在启动实时同步任务时可以选择全量同步，也可以不选择。
-* 如果选择了全量同步，系统会在启动增量同步时，也同时进行全量同步数据。全量同步的数据会写入到临时表，然后进行merge合并操作。全量同步完成后，会自动继续增量同步，不需要人为干预。
-* 全量同步，基于JDBC协议，连接到源端抽取数据，会对数据库有较大的读取压力。
-* 增量同步，基于数据库变更消息（比如MySQL的binlog），来解析其中内容，同步写入到目标端。对于数据库的压力主要是连接串的压力，相比全量同步，压力会小很多。
-
-### 两种同步模式：多表镜像同步和多表合并同步
-
-这两种模式的区别在于源端的表如何写入到目标端。
-
-* 多表镜像同步，目标端的表和源端的表是一一对应的。
-* 多表合并同步，支持把源端多张表合并写入到目标端一张表中。这种模式适合于源端是分库分表场景。多表合并同步，要求源端表的字段结构完全一致，或者基本一致。
-
-## 原理介绍
-
-### 流程原理
-
-主要步骤如下：
-
-* 启动增量同步，将源端变更数据，同步写入到目标表中。
-
-* 进行全量同步，将数据存量数据，同步到临时表，此过程增量同步不停止。
-
-* 全量同步完成后，将临时表的数据合并到目标表中，此过程会先停止增量同步，暂停消费源端数据库的变更。
-
-* 合并完成后，恢复增量同步。
-
-## 使用和运维指南
-
-### 常规使用：在进行实时同步前，对源端数据库需要进行哪些参数设置和权限准备？
-
-对源端数据库，需要进行必要的参数和权限配置，以确保数据库变更日志工作正常和同步任务具备足够权限能够正常获取到数据，
-
-#### 数据库参数配置
-
-**PostgreSQL**
-
-注意：修改以下参数需要重启Postgresql Server后生效。
-

-#### 数据库权限配置
-
-同步不同类型数据源的变更事件时，需要在相应数据源服务端配置好适当的权限才能保证数据的正常同步。尽管直接分配一个管理员或超级用户的权限足够保证任务正常运行，但通常会希望能够最小化权限需要分配给同步数据的用户的权限。各操作步骤需要的具体权限配置说明如下。
-
-**PostgreSQL**
-
-请注意，在执行赋权SQL语句时，确保执行账号自身具备可以授权的权限，建议使用管理员账号。为了确保任务顺利运行，建议将下述所有场景的授权均执行一遍。
-
-**使用场景：配置任务（获取元数据：schema列表、table列表、table字段列表**）
-
-所需权限：
-
-> SELECT（information\_schema和需要获取详情的table上）
-
-授权方式
-
-* 赋予某个角色读取information\_schema的权限：
-
-  ```SQL
-    GRANT SELECT ON TABLE information_schema.tables TO role_name; 
-  ```
-
-* 赋予某个角色读取某张表的权限：
-
-  ```SQL
-    GRANT SELECT ON TABLE your_schema.your_table TO role_name;
-  ```

-
-### 常规使用：如何配置和运行实时同步任务同步？
-
-通过以下步骤，按序操作：
-
-1. 在任务开发中配置同步任务，选择合适的镜像同步/多表合并同步模式，选定同步对象和正确的目标schema。
-2. 保存任务配置内容。
-3. 在调度配置中，选择合适的同步型集群，作为任务的资源，保存。
-4. 提交任务到运维中心。
-5. 在运维中心，操作启动任务。特别注意按需选择是否需要进行全量同步（此选项仅在任务提交上线后第一次启动时可以选择）。
-
-### 常规使用：配置同步任务，如何选择源端数据对象？
-
-* 多表镜像同步模式，源端表的选择相对简单，按照页面指引，否选需要同步的库表即可。
-
-* 多表合并同步模式，相对更加复杂，需要基于“虚拟表”的概念来进行操作。
-
-  * “虚拟表”核心作用是用来定义将源端哪些表同步到一张表中
-  * 新建“虚拟表”时，可以基于数据源、Schema、Table名称，给定筛选条件，来全选需要同步的源端表的范围，然后把这些表，定义成写入到同一张“虚拟表”。
-  * 系统会基于“虚拟表”的命名，在目标端Lakehouse中自动创建出目标表。
-
-### 常规使用：在同步过程中，期待在目标表中额外新增字段来记录来源信息，需要如何配置？
-
-* 可以在任务配置时，开启使用扩展字段功能。
-
-* 扩展字段目前支持设置源端server名称、database名称、schema名称和table名称。
-
-  ![](.topwrite/assets/image_1740314767939.png =680)
-
-### 常规使用：在同步过程中，如果源端表中，不同分库分表里面，存在主键相同记录，需要如何配置同步任务来避免数据写入冲突？
-
-* 可以在任务配置时，开启使用扩展字段功能，并把扩展字段设置为目标表的联合主键。
-
-  ![](.topwrite/assets/image_1740314789823.png =680)
-
-### 常规使用：如果源端的分库分表，表的字段结构基本一致，但又不是完全相同， 部分表多一些字段，如何配置同步任务？
-
-* 使用异构字段合并功能。
-* 在配置虚拟表时，系统会自动校验源端表的字段结构是否完全一致，如果不一致，系统会提示出来，依据提示，选择
-
-### 常规使用：如果任务第一次启动没有选择全量同步，后续想补充进行全量同步，如何操作？
-
-有如下几种方案可以使用：
-
-* 方案一：操作单表进行重新同步。
-
-  * 重新同步，会先把源端表同步到临时表中，然后通过insert overwrite写入到目标表中。
-  * 重新同步不会影响目标表的数据查询。
-
-* 方案二：操作单表进行补数同步，在过滤条件中，给一个能全量拉取到源端表的条件，比如 where 1=1 。
-
-  * 除了给where条件之外，也可以按需选择其它条件进行过滤，比如数据源名称、数据表名称。
-
-* 方案三：把同步任务停止、下线、然后再上线。启动任务时，选择进行全量同步。
-
-  * 停止和下线任务不会删除目标表。
-  * 停止任务，会使得目标表中的数据不再更新，基于目标表查询到的数据不是最新、会有延迟。
-  * 下线任务会清空同步位点等中间信息，无法做到从停止的位置继续续传。重新上线任务、启动后，只能重新开始进行全量同步和增量同步。
-
-### 常规使用：任务启动后，如果想新增更多表进行同步，需要如何操作？
-
-* 编辑任务，添加需要新增的表，保存任务。
-
-* 提交任务发布。
-
-* 在运维中心，操作停止任务、再启动任务。
-
-  * 重启后，会自动同步新增的表的数据。如果任务设定了要全量同步，会执行全量同步；反之只做增量同步。
-
-### 常规使用：分库分表，加减数据源、schema、table，需要如何操作，有什么影响？
-
-* 在任务开发界面，直接编辑即可。
-* 添加对象后，需要保存、提交，提交之后重启任务才能生效。
-* 任务重启后，会开始同步数据，如果任务设定为会全量同步，新增的对象也会自动进行全量同步。
-* 不会影响存量表的同步进度。
-
-### 常规使用：任务启动后，对所有表都进行全量同步耗时较长，如何优先同步重要的表？
-
-* 在正在进行全量同步的重要单表上，使用“优先执行”，会在资源队列中插队、优先处理，进行全量同步。
-
-### 常规使用：任务启动后，如何查看表的全量同步状态和详情？
-
-* 在运维中心，实时同步任务页面，同步对象区域，可以看到表的全量同步状态。
-* 在表的“操作”中，通过“全量同步详情”操作，可以查看全量同步实例的详细情况，包含任务实例的配置、详细日志等详情。
-
-### 常规使用：任务启动后，如何对任务中的特定表进行重新同步，有什么影响？
-
-* 如果需要修复特定表中的数据，选择“重新同步”：
-
-  * “重新同步”操作，会先重新同步源端表中的数据到临时表中，然后通过insert overwrite写入到目标表中，会重写掉目标表中已存在的数据。但不影响该目标表的查询。
-
-* 如果要从源端重新拉取全量数据/部分数据，选择“补数同步”：
-
-  * “补数同步”操作，会按照给定的过滤条件，从源端拉取数据到临时表中，然后delete目标表的相关数据，最后通过merge into的方式写入到目标表。
-
-### 常规使用：如果想暂时停止增量数据同步，需要如何操作？
-
-* 在运维中心的实时同步详情页，点击“停止”按钮，即可停止所有表的增量消息消费、不再进行同步。
-
-  * 注：不需要下线任务。
-
-* 如果想要恢复同步，点击“启动”按钮。
-
-* 点击“启动”按钮后，在弹框中，默认选择“从上次保存状态恢复”即可，系统会自动从上次停止为止续传处理。
-
-* 如果要进行回溯，可选择“自定义起始位置”，给点具体的位点/文件来回追数据。如下图以MySQL为例，请确保填写的binlog位点没有过期失效。
-
-### 常规使用：任务启动后，如何暂停和恢复单表的增量同步？
-
-* 在单边的运维操作菜单中，选择“停止增量同步”，会暂停该表的变更数据的增量同步，不再写入到目标表中。
-
-* 对于暂停增量同步的表，操作“恢复增量同步”，会重新启动该表的变更数据的增量同步，写入到目标表中。
-
-  * 为了保证数据的连续性，在恢复增量同步时，会从源端重新拉取一次全量数据。
-
-### 常规使用：下线实时同步任务有何影响？在什么情况下需要下线任务？
-
-* 下线任务属于相对高危的操作，建议谨慎使用，非必要不使用。
-* 停止实时同步任务、下线掉， 不会清理目标表中的数据、不会删除目标表，但会清理中间过程的缓存数据和位点信息。
-* 如果任务确定不再需要使用，可以下线任务。
-* 如果遇到任务状态异常等偶发情况，期望对任务进行一次修复，可以尝试下线任务后再上线任务。
-* 下线任务、再次上线并启动任务，会重新开始同步数据。重新同步不会重新建表，全量数据同步会对于老的表进行覆盖写入，增量同步会对目标表做merge into的更新。
-
-### 常规使用：如果同步任务中数据表和数据量特别大，做性能调优，可以通过哪些参数来设置？
-
-* 在任务配置中的参数，通常保持默认值即可。
-
-* 如果全量数据特别大，期待加速同步速度，在任务的“配置”中，可以适当调大以下两个参数的取值：
-
-  * step1.taskmanager.memory.process.size，比如设定为4000m（默认：1728m）
-
-  * step1.taskmanager.memory.task.off-heap.size，比如设定为500M（默认：256M）
-

-
-### 紧急运维：任务失败后，遇到无法自行处理的问题，如何配合云器排查？
-
-* 第一时间可通过飞书、电话等方式联系云器技术支持人员，云器方在接收到电话或者飞书信息后会快速做出响应并启动问题处置流程。
-* 由于是OP部署环境，存在网络隔离等原因，需要客户配合获取任务执行日志等信息，以便快速排查解决问题。
-
-### 紧急运维：如果源头突发多张表的流量很大，影响部分重要表的同步消费，如何处理？
-
-* 可以对相对不重要的表，使用“暂停增量同步”功能，暂停该表的变更消息消费，为重要表的同步让出处理资源。
-* 在重要表的变更消费完成后，再回复被暂停表的增量同步。
-
-## 任务监控和告警
-
-### 任务详情运维页面监控指标的含义
-
-#### 阶段监控
-
-任务启动后，会经历初始化、全量同步、增量同步三个阶段。可在实例监控区域查看这三个阶段的运行状态。

-
-## 常见报错排查
-
-### 增量同步失败
-
-#### Binlog位点过期
-
-* 问题现象
-
-  * 以指定文件和位点的方式启动任务，或者任务停止一段时间后选择从状态恢复启动后任务失败，执行日志中报错：Caused by: java.lang.IllegalStateException: The connector is trying to read binlog starting at Struct{version=1.9.7.Final,connector=mysql,name=mysql\_binlog\_source,ts\_ms=1734071479878,db=,server\_id=0,file=mysql-bin.010937,pos=432041283,row=0}, but this is no longer available on the server. Reconfigure the connector to use a snapshot when needed.
-
-* 可能原因
-
-  * Mysql的binlog通常不会永久保存，会被定期回收，如果指定了一个已经被清理的binlog文件或位点，或者任务停止了很长时间，自动从状态恢复的时候会继续从上次暂停的一个被清理的位点继续消费，则会遇到上述报错，因为对应的binlog数据已经被删除。
-
-* 解决措施
-
-  * 通过`show master status` 查询当前数据库的最新binlog文件和位点：
-
-    ![](.topwrite/assets/image_1740315126085.png =460)
-
-  * 使用结果中的file和position重启同步任务
-
-    ![](.topwrite/assets/image_1740315139248.png =460)
-
-  * 如果需要补回丢失的数据，可以选择相应的表进行重新同步
-
-#### Server-id冲突
-
-* 问题现象
-
-  * 任务启动失败，执行日志中报错：A slave with the same server\_uuid/server\_id as this slave has connected to the master; the first event '' at 4, the last event read from '/home/mysql/log/mysql/mysql-bin.011268' at 90995258, the last byte read from '/home/mysql/log/mysql/mysql-bin.011268' at 90995258. **Error** code: 1236; SQLSTATE: HY000. The 'server-id' in the mysql cdc connector should be globally unique, but conflicts happen now.
-* 可能原因
-
-  * 实时同步任务默认在为每个mysql数据源建立一个连接并分配一个server-id用来同步binlog数据，生成的server-id的范围在5400-6400之间，如果出现上述报错导致任务失败，说明本次任务为这个数据库连接分配的server-id与数据库上的其他同步工具或同步任务发生了冲突。
-* 解决措施
-
-  * 检查同一个数据库实例下是否有其他同步任务或同步工具正在同步binlog数据
-  * 重启同步任务
-
-#### 数据源时区配置错误
-
-* 问题现象
-
-  * 任务启动失败，执行日志中报错：Caused by: org.apache.flink.table.api.ValidationException: The MySQL server has a timezone offset (28800 seconds ahead of UTC) which does not match the configured timezone Etc/GMT+12. Specify the right server-time-zone to avoid inconsistencies for time-related fields.
-
-* 可能原因
-
-  * 数据源中配置的时区（默认东八区，Asia/Shanghai）与数据库配置的时区不一致。
-
-* 解决措施
-
-  * 确认数据库配置的时区，然后修改数据源中配置的时区
-
-#### Binlog事件size超限
-
-* 问题现象
-
-  * 任务运行失败，执行日志中报错Caused by: io.debezium.DebeziumException: log event entry exceeded max\_allowed\_packet; Increase max\_allowed\_packet on master; the first event '' at 58722808, the last event read from '/rdsdbdata/log/binlog/mysql-bin-changelog.004054' at 109251835, the last byte read from '/rdsdbdata/log/binlog/mysql-bin-changelog.004054' at 109251854. Error code: 1236; SQLSTATE: HY000.
-
-* 可能原因
-
-  * 数据库配置的`max_allowed_packet`小于Binlog中的某个事件的size
-  * 数据库binlog文件损坏
-
-* 解决措施
-
-  * 联系dba调整数据库的`max_allowed_packet`参数大小，可调整的上限为1G，生效后重新同步
-  * 如果调整`max_allowed_packet` 参数后仍然无法成功，则binlog文件可能已经损坏，可以重启任务，选择一个更新的点位，即跳过有问题的位点来继续同步增量数据；如果需要补全中间可能缺少的数据，选择需要补全数据的表重新同步全量数据
-
-### 全量同步失败
-
-#### PK长度超限
-
-* 问题现象
-
-  * 全量同步状态失败，执行日志中报错：BulkLoad stream errorcom.dtstack.flinkx.throwable.FlinkxRuntimeException: BulkLoad failed, stream id: bulkload\_stream\_xxx final status\:COMMIT\_FAILED, error msg\:Task lost connection, message: container stopped by AM. Detail CZLH-71006\:Encoded key size 191 exceeds max size 128
-
-* 可能原因
-
-  * 源表中的主键字段总长度过程，超过默认配置的128字节
-  * 同步任务配置中选择了多个扩展字段作为联合主键，如多表合并场景中选择了server\_id、database、schema、table作为联合主键来避免多个表中的主键字段有冲突，扩展后的联合主键总长度超过默认配置的128字节
-
-* 解决措施
-
-  * 修改同步任务，增加配置：
-
-  ```Bash
-    step1.containerized.taskmanager.env.pk_encoded_key_override_size 256step2.containerized.taskmanager.env.pk_encoded_key_override_size 256
-  ```
-
-### 同步任务Failover
-
-#### 与Lakehouse Ingestion Service断连
-
-* 问题现象
-
-  * 任务发生failover，failover详情中有如下信息：java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.lang.RuntimeException: java.io.IOException: Async commit for instance \[270076] workspace \[xsy\_ent] failed. Error detail is\:rpcProxy call hit final failed after max retry reached. at com.dtstack.flinkx.connector.lakehouse.sink.LakeHouseRedisMetaHybridIgsMultiWriter.flushInternal
-
-* 可能原因
-
-  * 通常发生在Lakehouse服务端升级的情况下，数据同步任务与Lakehouse Ingestion Service连接中断
-
-* 解决措施
-
-  * 一般发生在服务升级期间，通常在完成升级后任务会自动恢复
-  * 如果确认服务升级完成，任务还在持续failover，尝试手动重启任务
-  * 如果手动重启任务后任务还是无法恢复正常，需要检查Lakehouse Ingestion Service服务健康状态
-
-#### Binlog事件反序列化失败
-
-* 问题现象
-
-  * 任务发生failover，failover详情中有如下信息：com.github.shyiko.mysql.binlog.event.deserialization.EventDataDeserializationException: Failed to deserialize data of EventHeaderV4
-
-* 可能原因
-
-  * 这个问题通常出现在来源数据库的binlog中突然产生了大量的事件，如发生大量业务数据的更新，或历史数据批量删除等场景，导致同步任务写入端无法在短时间内处理完所有数据，发生反压，同步任务的读取端停止消费binlog数据，同步任务中的binlog client与数据库服务端的连接会被任务超时而中断，或者服务端的处理线程idle过久被回收，都有可能导致同步任务接受到不完整的binlog事件消息，从而导致反序列化失败
-
-* 解决措施
-
-  * 如果流量的增长是短时间的，通常同步任务能够在有限的failover次数内恢复正常
-  * 如果持续长时间出现，可尝试调整mysql配置，调大slave\_net\_timeout和thread\_pool\_idle\_timeout的值，
-  * 临时调整（MySQL实例重启会失效）：
-
-  ```SQL
-    set global slave_net_timeout = 120; -- default 60 secondsset global thread_pool_idle_timeout = 120; -- default 60 seconds
-  ```
-
-  * 永久调整，修改MySQL的配置文件
-
-  ```Bash
-    [mysqld]slave_net_timeout = 120thread_pool_idle_timeout = 120
-  ```
-
-### 表进入黑名单
-
-#### 执行Schema evolution失败
-
-* 问题现象
-
-  *   某张表的状态自动变为停止同步状态，表对象边上的tips看到有`pk column different`、`pk column type mismatch`、`invalid modify column`等错误信息
-
-* 可能原因
-
-  * 来源表结构发生了Lakehouse不支持的变更，包括：
-  * PK字段列表变更，如PK字段重命名，或从原来的一个字段变成两个字段
-  * PK字段类型变更，如将PK字段的类型从bigint改为varchar
-  * 字段类型发生不兼容修改，如从int改为double等
-
-* 解决措施
-
-  * 检查源端表结构，修改为正确的结构
-  * 重新全量同步停止增量同步的表，全量同步完成后相应的增量数据也会继续同步
-
-## 已知局限和注意事项
-
-* 为保证目标端数据写入不出现冲突，仅支持对源端是带主键PK字段的表配置同步，非PK表不支持同步。
-* 在同步任务中会自动创建目标表，为了确保任务运行稳定和数据正确，无特别必要，不要手动去创建表、修改表和删除表。
-* Schema Evolution，支持源端新增字段、删除字段，暂不支持变更字段类型、不支持自动新增表。

-
-### 2️⃣ 检查端口（推荐）
-
-在部署前检查所需端口是否可用：
-
-**Windows**:
-```cmd
-check-ports.bat
-```
-
-**macOS/Linux**:
-```bash
-./check-ports.sh
-```
-
-检查脚本会自动检测所有必需端口是否可用。如果发现端口冲突，可以：
-
-1.  停止占用端口的服务
-2.  或在运行 `./deploy.sh setup` 后编辑 `.env` 文件修改相应端口
-
-### 3️⃣ 初始化配置
-
-**Windows**:
-```cmd
-deploy.bat setup
-```
-
-**macOS/Linux**:
-```bash

-# 修改统一入口端口（默认 80）
-HTTP_PORT=8080
-
-# 配置 N8N 公共 URL（用于生成邀请链接等）
-N8N_PUBLIC_URL=http://172.17.1.220/n8n
-
-# 修改 API 工作进程数（默认 4）
-API_WORKERS=8
-
-# 修改数据库端口（如果需要外部访问）
-POSTGRES_PORT=5433
-```
-
-## 🔧 诊断工具
-
-### check-env-vars.sh 使用指南
-
-当遇到数据库连接或认证问题时，使用此工具进行诊断：
-
-```bash
-./check-env-vars.sh
-```
-
-**适用场景**：
-
-* N8N 或 API 服务报告 "password authentication failed"
-* 需要验证环境变量是否正确传递给容器
-* 检查容器内实际使用的配置值
-
-**功能说明**：
-
-1. 显示 `.env` 文件中的配置
-2. 展示 Docker Compose 解析后的环境变量
-3. 检查运行中容器的实际环境变量
-4. 测试数据库连接是否正常
-
-**示例输出**：
-
-```bash
-=== 环境变量检查工具 ===
-
-1. 检查 .env 文件内容:
-POSTGRES_PASSWORD 设置: VUEk30jlqj6rd48U
-
-2. Docker Compose 解析后的环境变量:
-[显示各服务的环境变量配置]
-
-3. 运行中容器的实际环境变量:
-[显示容器内的实际环境变量]
-
-4. 测试数据库连接:
-✓ 可以使用 .env 密码连接
-```
-
-如果发现密码不匹配，通常需要清理并重新部署：
-
-```bash
-./deploy.sh clean
-./deploy.sh setup
-./deploy.sh init
-```
-
-## 🔄 更新部署
-
-当有新版本发布时，可以使用以下步骤更新：
-
-### 保留配置的更新
-
-```bash
-# 1. 备份当前配置（推荐）
-cp .env .env.backup
-
-# 2. 下载最新版本（覆盖旧文件）
-curl -L -O https://github.com/yunqiqiliang/clickzetta_quickstart/raw/main/datadiff_n8n_clickzetta/data-diff-n8n-deploy-latest.zip
-
-# 3. 解压并覆盖（除了 .env 文件）
-unzip -o data-diff-n8n-deploy-latest.zip -x "data-diff-n8n/.env"
-
-# 4. 重启服务
-./deploy.sh restart
-```
-
-### 完全覆盖更新
-
-```bash
-# 警告：这会覆盖所有文件，包括配置
-unzip -o data-diff-n8n-deploy-latest.zip
-```
-
-💡 **提示**：
-
-* `-o` 参数表示自动覆盖所有文件，不询问。
-* `-x` 参数可以排除特定文件不被覆盖。
-* 建议总是先备份 `.env` 文件，其中包含您的密码配置。
-
-## 🚨 故障排除
-
-### 端口被占用
-
-默认使用 80 端口作为统一入口。如果 80 端口被占用：
-
-1. 编辑 `.env` 文件，修改 `HTTP_PORT`：
-
-   ```env
-   HTTP_PORT=8080  # 或其他可用端口
-   ```
-
-2. 重启服务：
-
-   ```bash
-   ./deploy.sh restart
-   ```
-
-3. 访问新端口：
-
-   ```bash
-   http://localhost:8080
-   ```
-
-### Docker 未运行
-
-确保 Docker Desktop 已启动并正在运行。
-
-### 服务无法访问
-
-1. 使用 `deploy.bat status` 检查服务状态
-2. 使用 `deploy.bat logs` 查看错误日志
-3. 确保防火墙允许相应端口访问
-
-### 数据库初始化错误
-
-如果看到以下错误：
-
-* `数据库初始化失败：datadiff 数据库不存在`
-* `数据库表未正确创建`
-* `password authentication failed for user "postgres"`
-* `relation "data_diff_results.comparison_summary" does not exist`
-
-**原因**：
-
-1.  PostgreSQL 数据卷保留了旧的配置或密码。
-2.  数据库初始化脚本未能执行（PostgreSQL 只在首次创建数据卷时执行 `/docker-entrypoint-initdb.d/` 中的脚本）。
-
-**解决方案**：
-
-```bash
-# 完全清理并重新部署./deploy.sh clean./deploy.sh setup./deploy.sh init
-```
-
-**说明**：
-
-* PostgreSQL 使用 Docker 卷存储数据，首次启动时会执行 `init-databases.sql`
-* 如果数据卷已存在，即使更新了 SQL 文件也不会重新执行
-* `clean` 命令会删除数据卷，确保下次启动时重新初始化
-
-**重要**：`clean` 命令会删除所有数据，请确保已备份重要数据。
-
-## 📚 进阶使用
-
-### 创建第一个比对工作流
-
-1. 访问 N8N (<http://localhost/n8n/>)
-
-2. 使用 `.env` 中的凭据登录

-Navicat（全称 Navicat Premium）是一款功能强大的数据库管理工具，广泛应用于数据库开发、管理和维护。本文介绍如何使用 Navicat 通过 MySQL 协议连接 Lakehouse。
-
-# 准备工作
-
-* 请参考[Navicat官网](https://www.navicat.com/en/download/navicat-premium)，如果已经安装完毕请跳过。
-
-* 使用Mysql协议连接。目前需要重置密码，即使是新建的账号也需要重置密码。这是因为 MySQL 5.x 版本使用的是 `mysql_native_password` 密钥，而 Lakehouse 需要保存 MySQL 的加密算法。目前，只有在修改密码时，Lakehouse 才会保存 MySQL 密钥的加密算法。您可以修改密码时保持和之前一样这样可以避免影响别的任务连接
-
-* 给用户设置计算集群，由于 MySQL 协议中没有传入设置集群的方式，用户可以使用 SQL 命令为用户添加一个默认计算集群。这样在 MySQL 连接时就会使用该集群。
-
-  * ```SQL
-    ALTER USER user_name SET DEFAULT_VCLUSTER = default;-- 查看集群设置是否生效SHOW USERS;
-    ```
-
-* 准备用户名。 使用 MySQL 协议连接时，地址中只能传入一个 URL，无法拼接 Lakehouse 的 instance_name 和 workspace_name。因此，需要将 instance_name 和 workspace_name 拼接到用户名中。
-
-  * 用户名格式要求如下：
-  * ```Plain
-    登录的账号名称@instance_name.workspace_name
-    ```
-  * **instance_name 获取**：在 工作空间页面 中获取 JDBC 连接串。例如，在 `jdbc:clickzetta://``demoinstance.cn-shanghai-alicloud.api.clickzetta.com/quick_start?virtualCluster=default` 中，`jnsxwfyr` 为 instance\_name。
-  * **workspace\_name 获取**：工作空间的名称。
-
-# 连接Lakehouse
-
-* 点击连接->选择MySQL
-
-* 填写配置信息，如下
-
-| 字段       | 说明                                                    |

-| **主机**   | 每个region的连接地址，具体参考[使用MySQL协议连接 ](use-mysql-client.md) |
-| **端口**   | 可选。默认值:3306                                           |
-| **用户名**  | 登录的账号名称@instance\_name.workspace\_name                |

-## 1. 概述
-
-**网络策略（Network Policy**） 旨在控制对某个服务实例（instance）的访问来源，常用做以下场景：
-
-* 限制仅允许特定的 IP 或网段访问Lakehouse 服务实例的Web服务。
-* 限制仅允许特定的 IP 或网段使用JDBC连接Lakehouse服务实例。
-* 阻止（黑名单）可疑或风险 IP 地址段。
-* 在需要时，为了不影响生产或管理员登录，具备实例管理员角色（instance\_admin）的用户可**临时绕过**并修改网络策略设置。
-
-在实际运维中，结合 IP 白名单、黑名单可显著增强数据的安全性与合规性。
-
-***
-
-## 2. 网络策略（Network Policy）简介
-
-* **核心功能**：通过白名单（Allow\_IP\_List）和黑名单（Block\_IP\_List）来控制哪些网络来源可以访问目标服务实例。
-* **典型效果**：
-  1. 管理和过滤 IP 地址或网段。
-  2. 同时支持白名单（Allow\_IP\_List）和黑名单（Block\_IP\_List）方式配置网络策略。
-  3. 当多条策略生效并叠加时，采用“Deny 优先”原则。
-
-***
-
-## 3. 网络策略的工作原理与使用场景
-
-### 3.1 默认逻辑
-
-* **当系统无任何网络策略**时，默认允许所有 IP 访问（相当于“Allow 0.0.0.0/0”）。
-* 一旦创建并激活了至少一条网络策略，系统会根据**所有生效策略**的白名单及黑名单规则进行过滤。
-
-### 3.2 白名单（Allow）与黑名单（Block）的运算
-
-在同一条网络策略中或多条生效策略的结果中：
-
-* 如果有任一生效的白名单策略，则没有在白名单策略中的某个IP/网段将被阻止。
-* 如果没有任何生效的白名单，则除生效的黑名单指定的IP/网段外，其他IP/网段将被放行。
-* 最终出现任意黑名单规则命中时，该 IP 即被拒绝。
-
-### 3.3 多条策略生效与优先级
-
-* 多条策略并行生效时，白名单取并集，黑名单取并集。
-* 多条网络策略之间无优先级关系，系统会对所有生效的网络策略做逻辑运算，并得出当前最终的网络策略结果。
-
-### 3.4 适用范围
-
-网络策略适用于控制从外部网络访问Lakehouse服务的请求，访问方式包括：
-
-* JDBC
-* SDK
-* Web页面
-
-特殊情况说明：
-
-* MySQL兼容协议访问Lakehouse时，只要有“生效”状态的网络策略，无论白名单、黑名单的内容，均会拦截所有MySQL流量。
-
-***
-
-## 4. 核心属性与限制
-
-### 4.1 网络策略属性
-
-| 属性名称                | 是否必填 | 取值范围                                | 默认值      | 说明                               |
-| ------------------- | ---- | ----------------------------------- | -------- | -------------------------------- |
-| **Name**            | 是    | 字母或下划线开头，3-28 个字符，自动转小写，仅限字母/数字/下划线 | 无        | 策略名称在实例内唯一。                      |
-| **Allow\_IP\_List** | 是    | IPv4 单 IP 或 CIDR，逗号分隔，数量上限 \~10 万   | 无        | 允许访问的 IP 或网段。 不允许出现 `0.0.0.0/0`。 |
-| **Block\_IP\_List** | 否    | IPv4 单 IP 或 CIDR，逗号分隔，数量上限 \~10 万   | 无        | 阻止访问的 IP 或网段。 不允许出现 `0.0.0.0/0`。 |
-| **Status**          | 是    | `Activate` 或 `Inactive`             | Activate | 新建默认“生效”，可同时存在多条生效策略。            |
-
-### 4.2 限制与注意事项
-
-1. **最大策略数**：同一实例最多可创建 20条网络策略。
-2. **单策略 IP 数量限制**：白名单、黑名单各自最多可各容纳 10 万个 IP/CIDR。
-3. **策略生效延迟**：网络策略存在缓存生效机制，一般最多 5 分钟内生效。
-4. **删除后不可恢复**：请谨慎操作。尤其多条网络策略同时生效时，逻辑关系较为复杂，删除已生效的策略，可能会导致禁止或允许访问的范围产生较大变化。
-
-***
-
-## 5. 操作指南
-
-以下操作可通过 SQL 命令或前端管理控制台来完成，具体以您所在产品的实际实现为准。
-
-### 5.1 创建网络策略
-
-该操作仅限具备实例管理员（instance\_admin）角色的用户执行。
-
-**Web 操作**：
-
-在“管理”-“安全”-“网络策略”功能中，点击“+新建策略”。
-
-在弹窗中填写“策略名称”，并根据实际需要填写IP白名单或IP黑名单中的内容。
-
-:-: ![](.topwrite/assets/image_1742472677609.png =791)
-
-**SQL 操作**：
-
-```sql
-CREATE [ OR REPLACE ] NETWORK POLICY <name>
-ALLOWED_IP_LIST = ( [ '<ip_address>' ] [ , '<ip_address>' , ... ] )
-[ BLOCKED_IP_LIST = ( [ '<ip_address>' ] [ , '<ip_address>' , ... ] ) ];
-
-
---示例：
-CREATE NETWORK POLICY policy1
-  ALLOWED_IP_LIST = ('192.168.11.1','192.168.11.2','10.0.0.1/24')
-  BLOCKED_IP_LIST = ('192.168.11.99');
-```
-
-注意：
-
-* 同一个服务实例中，网络策略的名称不可重复。
-* 白名单和黑名单中支持填写 IPV4 IP或CIDR，但不支持0.0.0.0/0。 当白名单为空时，表示全部允许。
-* 同一条网络策略中，白名单或黑名单内的IP/CIDR不允许重复添加，但允许存在交集。不同网络策略中，白名单或黑名单内的IP/CIDR允许重复或存在交集。
-* 创建成功后状态默认为 `Activate`（可立即生效或可被再次激活/使用，视产品而定）。
-* 当前访问Lakehouse所使用的IP也可被写入白名单/黑名单内。如果将当前使用的IP加入黑名单，将导致策略生效后，对当前服务实例的访问立即被阻止。请谨慎操作。
-
-### 5.3 修改网络策略
-
-**Web 操作**：
-
-在“管理”-“安全”-“网络策略”功能中，在需要修改的网络策略右侧的“操作”栏中点击“编辑”按钮，在弹窗中对该网络策略进行修改。
-
-其中，
-
-网络策略的名称不允许修改。仅可以修改网络策略中的白名单/黑名单所包含的IP内容。
-
-:-: ![](.topwrite/assets/image_1742472725009.png =783)
-
-**SQL 操作**：
-
-```
-ALTER NETWORK POLICY [ IF EXISTS ] <name>
-SET 
-  ALLOWED_IP_LIST = ( [ '<ip_address>' ] [ , '<ip_address>' , ... ] )
-[ BLOCKED_IP_LIST = ( [ '<ip_address>' ] [ , '<ip_address>' , ... ] ) ];
-
---示例：
-ALTER NETWORK POLICY policy1
-SET 
-	ALLOWED_IP_LIST = ('192.168.11.1')
-	BLOCKED_IP_LIST = ('192.168.11.99');
-```
-
-注意：
-
-* 修改网络策略的SQL操作是\*\*“覆盖”**操作，ALTER语句中务必包含ALLOWED\_IP\_LIST和BLOCKED\_IP\_LIST中**所有\*\*需要允许和拒绝的IP范围。
-
-例如：
-
-```
---创建一条示例的网络策略
-CREATE NETWORK POLICY policy1
-  BLOCKED_IP_LIST = ('192.168.11.99');
-
---以下语句执行后的policy1，仅包含ALLOWED_IP_LIST = ('192.168.11.100')
-ALTER NETWORK POLICY policy1 SET 
-ALLOWED_IP_LIST = ('192.168.11.100');
-
---不执行上面的ALTER语句，而执行以下ALTER语句修改网络策略后，policy1中包含：ALLOWED_IP_LIST = ('192.168.11.1'）和BLOCKED_IP_LIST = ('192.168.11.99')
-ALTER NETWORK POLICY policy1
-SET 
-	ALLOWED_IP_LIST = ('192.168.11.1')
-	BLOCKED_IP_LIST = ('192.168.11.99');
-
-```
-
-### 5.4 生效/失效网络策略
-
-**Web 操作**：
-
-在“管理”-“安全”-“网络策略”功能中，在需要修改的网络策略右侧的“操作”栏中点击“停用”/“启用”按钮，即可切换网络策略的状态。
-
-:-: ![](.topwrite/assets/image_1742472766197.png =799)
-
-**SQL 操作**：
-
-```
-ALTER NETWORK POLICY <name> ACTIVATE;
-ALTER NETWORK POLICY <name> INACTIVATE;
-
---示例：
-CREATE NETWORK POLICY policy1 ACTIVATE;
-CREATE NETWORK POLICY policy1 INACTIVATE;
-```
-
-* 可以在列表或详情处进行“置为生效/置为失效”操作。
-
-* 具体生效/失效后对其他策略的影响，依您的产品是否允许多策略生效而定（有的只允许单一账号策略有效，激活新策略会自动替换上一个；也有的允许多条策略并行）。
-
-### 5.5 删除网络策略
-
-**Web 操作**：
-
-在“管理”-“安全”-“网络策略”功能中，在需要修改的网络策略右侧的“操作”栏中点击“停用”/“启用”按钮，即可切换网络策略的状态。
-
-:-: ![](.topwrite/assets/image_1742472815202.png =793)
-
-**SQL 操作**：
-
-```
-DROP NETWORK POLICY  <name>;
-
---示例：
-drop network policy policy1;
-```
-
-* 删除后不可恢复。
-
-### 5.6 查看网络策略
-
-**Web 操作**：
-
-在“管理”-“安全”-“网络策略”功能中，可以查看当前服务实例中所有的网络策略。
-
-:-: ![](.topwrite/assets/image_1742472860368.png =783)
-
-**SQL 操作**：
-
-* **显示所有策略**：
-
-```
-SHOW NETWORK POLICY;
-```
-
-返回字段包括：
-
-| **字段**        | **说明**                   |
-| ------------- | ------------------------ |
-| NAME          | 策略名称                     |
-| CREATOR       | 创建者的username             |
-| CREATED\_TIME | 格式为：yyyy-mm-dd hh\:mm:ss |
-| STATUS        | active、inactive          |
-
-* **查看详情**：
-
-```
-DESC NETWORK POLICY <name>;
-```
-
-* 返回策略中 `ALLOWed_IP_LIST` / `BLOCKed_IP_LIST`
-
-| **字段**            | **说明**                   |
-| ----------------- | ------------------------ |
-| NAME              | 策略名称                     |
-| ALLOWED\_IP\_LIST | 创建者的username             |
-| BLOCKED\_IP\_LIST | 格式为：yyyy-mm-dd hh\:mm:ss |
-
-### 5.7 临时绕过网络策略访问
-
-* 在极端情况下（如白名单配错或黑名单阻止了所有网段），可由具备实例管理员角色（instance\_admin)的用户
-
-  创建**临时绕过**策略，使指定用户在 30 分钟内不受网络策略限制。
-
-* 在某些产品或环境中，该功能通过设置用户对象属性 `MINS_TO_BYPASS_NETWORK_POLICY` 来实现，需要联系管理员或官方支持来配置。
-
-***
-
-## 6. 权限与安全控制
-
-| Privilege code        | 操作                 | 默认授予角色 / 权限               |
-| --------------------- | ------------------ | ------------------------- |
-| create network policy | CREATE             | 仅授予实例管理员（instance\_admin） |
-| alter                 | ALTER/RENAME/激活/失效 | 仅授予实例管理员（instance\_admin） |
-| drop                  | DROP               | 仅授予实例管理员（instance\_admin） |
-| read metadata         | SHOW / DESC /      | 仅授予实例管理员（instance\_admin） |
-
-***
-
-## 7. 常见问题（FAQ）
-
-1. **同一个 IP 同时在白名单和黑名单出现，结果如何**？
-   * 黑名单优先，访问被阻断。
-2. **当没有创建任何网络策略时，默认是允许还是拒绝访问**？
-   * 默认允许所有 IP，等效于白名单包含所有IP。
-3. **为何禁止使用** \`\` **在白名单/黑名单中**？
-   * 该表示意味着“所有 IP”。在白名单中没有实际意义（表示开放全部），在黑名单中则完全阻断所有访问，如果没有例外规则，就会导致任何人都无法访问。
-4. **是否能对同一实例同时启用多条网络策略**？
-   * 允许同一服务实例创建多条网络策略且并行生效。系统将所有生效策略中的网络策略中的白名单/黑名单规则取并集后再应用。
-5. **如何避免实例管理员自己被策略锁住**？
-   * 在创建或激活策略前，请确保您自己的 IP（可在web端创建或修改网络策略时看到）已包含在白名单中。若仍意外被阻断，实例管理员（instance\_admin）可通过修改网络策略来恢复自己对服务实例的访问。

-## 智能数据处理实战
-
-### 第一步：数据质量诊断
-
-用户只需自然语言提问："*这些数据需要做哪些清洗转化提高分析效果*？"
-
-Claude Desktop通过云器Lakehouse MCP Server自动执行数据质量分析：
-
-**发现的主要问题**：
-
-* 空值问题：23,304 条记录（6.6%）的乘客数量为空
-* 异常值：16,850 条记录（4.8%）的行程距离 ≤ 0
-* 时间异常：1,713 条记录的下车时间早于上车时间
-* 费用计算错误：40,942 条记录（11.6%）费用计算不一致
-
-### 第二步：智能数据清洗
-
-用户请求："*请按顺序都执行*"
-
-Claude Desktop自动生成并执行清洗方案：
-
-#### 异常数据过滤
-
-```sql
--- 自动生成的清洗逻辑
-CREATE TABLE nyc_green_taxi_2025_cleaned AS 
-SELECT *,
-    -- 修复passenger_count空值
-    CASE 
-        WHEN passenger_count IS NULL THEN 1
-        WHEN passenger_count = 0 THEN 1  
-        WHEN passenger_count > 6 THEN 6
-        ELSE passenger_count
-    END as passenger_count_cleaned,
-    
-    -- 计算行程时长（分钟）
-    TIMESTAMPDIFF(MINUTE, lpep_pickup_datetime, lpep_dropoff_datetime) as trip_duration_minutes
-FROM nyc_green_taxi_2025
-WHERE 
-    lpep_dropoff_datetime > lpep_pickup_datetime
-    AND trip_distance > 0 AND trip_distance < 100
-    AND fare_amount > 0 AND fare_amount < 500
-    AND total_amount > 0 AND total_amount < 1000
-```
-
-**清洗效果**：
-
-* 数据保留率：93.93%（330,257 条有效记录）
-* 空值消除率：100%
-* 异常值清理率：100%
-
-### 第三步：时间维度增强
-

-
-```sql
--- 自动增加的时间分析字段
-ALTER TABLE nyc_green_taxi_2025_cleaned ADD COLUMNS (
-    pickup_year INT,
-    pickup_month INT,
-    pickup_hour INT,
-    pickup_dayofweek INT,
-    pickup_is_weekend BOOLEAN,
-    pickup_time_period STRING,  -- 早高峰/晚高峰/平时/深夜
-    pickup_season STRING        -- 春夏秋冬
-);
-```
-
-**时间模式洞察**：
-
-* 春季出行最多（28.82%）
-* 平时时段占比最高（63.83%）
-* 早高峰（7-9 点）和晚高峰（17-19 点）特征明显
-
-### 第四步：业务指标计算
-
-系统自动计算关键业务指标：
-
-```sql
--- 智能生成的业务指标
-trip_speed_mph,          -- 平均速度（英里/小时）
-fare_per_mile,           -- 每英里费用
-tip_rate,                -- 小费率
-trip_distance_category,  -- 距离分类（短途/中途/长途）
-fare_category,           -- 费用分类（低价/中价/高价）
-passenger_load_factor    -- 载客率分类
-```
-
-**业务洞察发现**：
-
-* 中途行程（1-5 英里）占主导地位（68.4%）。
-* 平均行程速度：12.0 英里/小时。
-* 信用卡支付占 74.79%，现金支付 24.26%。
-
-### 第五步：分类字段标准化
-
-将编码转换为可读标签：
-
-| 原始编码            | 标准化标签         | 占比     |
-| --------------- | ------------- | ------ |
-| vendorid=2      | VeriFone Inc  | 85.34% |
-| payment\_type=1 | Credit Card   | 74.79% |
-| ratecodeid=1    | Standard Rate | 94.28% |

-# 云器Lakehouse对象模型概览
-
-云器 Lakehouse 采用分层结构管理资源，以提高数据组织和访问的效率。以下是 Lakehouse 对象模型的详细说明和示例。
-
-![](.topwrite/assets/object-hierarchy.png)
-
-## 账户（Account）
-
-云器的账户是代表与云器公司建立商业关系的组织或个人（通常是企业账户），用于开通云器产品服务、付费、获取服务支持等。账户在注册时将自动生成一个全局唯一的账户名，作为您在云器产品中的唯一标识。
-
-**特点：**
-- 账户负责充值、出账单、费用支付以及订购或变更云器产品。
-- 所有企业或个人在云器产品上开通的服务实例及其资源对象都归属于特定账户。
-
-**示例：**
-假设您是一家名为“XYZ科技”的企业，注册云器账户后，系统为您生成的账户名为“xyztech0128”，您的账户 URL 为“xyztech0128.accounts.clickzetta.com”。
-
-## 用户（User）
-
-账户注册成功后，您可以创建多个用户共同使用同一个账户内的资源。不同用户间可以通过权限控制分配可使用的数据和资源。
-
-**示例：**
-在“XYZ科技”的账户下，您可以创建多个用户，如“alice”（负责数据分析）、“bob”（负责数据开发）等。您可以根据他们的职责分配不同的权限，确保数据安全和高效协作。
-
-## 服务实例（Lakehouse Instance）
-
-Lakehouse 服务实例是云器 Lakehouse 产品服务的载体。在开通 Lakehouse 服务时，您需要根据指定的云服务商和地域，在账户下创建服务实例。一个账户下可以创建一个或多个服务实例（当前阶段默认仅支持创建单个服务实例）。
-
-**特点：**
-- 服务实例采用统一元数据管理数据对象、计算资源、作业任务；
-- 服务实例具备区域属性，其计算、数据和其他服务资源均在此云服务商的区域内；
-- 不同服务实例间默认相互隔离。
-
-**示例：**
-“XYZ科技”需要在阿里云和腾讯云分别部署 Lakehouse 服务，可以在其账户下创建两个服务实例：“ali-lakehouse”和“tencent-lakehouse”。
-
-## 工作空间（Workspace）
-
-工作空间是用于组织 Lakehouse 资源对象（数据对象、计算资源、用户等）并提供配套数据开发能力的逻辑对象。一个服务实例下可以创建多个工作空间。工作空间之间默认隔离，用户需加入工作空间，才可使用该工作空间内的对象。同一实例下不同工作空间内的对象，可通过跨工作空间授权的方式实现共享。
-
-**特点：**
-- 工作空间用于组织和管理数据开发、计算资源等对象。
-- 工作空间之间相互隔离，确保数据安全和高效协作。
-
-**示例：**
-在“ali-lakehouse”服务实例下，您可以创建两个工作空间：“data-dev”（负责数据开发）和“data-ops”（负责数据运维）。
-
-## 计算资源（Virtual Cluster）
-
-计算资源由多实例虚拟计算集群和运行在集群中的计算服务构成，为用户作业提供计算环境，包括 CPU、内存以及临时存储。
-
-## Schema
-
-在工作空间内，Schema 是一组数据库对象的命名空间。数据库对象包括表、视图等。一个工作空间内可以包含多个命名各异的 Schema。
-
-## 表（Table）
-
-表是格式化的二维数据表格。
-
-## 视图（View）
-
-视图是一种虚拟存在的表，并不在数据库中实际存在，在使用时动态生成。
-
-## 物化视图（Materialized View）
-
-物化视图是一种特殊的视图，相对普通视图，物化视图在数据库中实际存在，并占用存储资源。
-
-## Lakehouse SQL任务（JOB）
-
-Lakehouse SQL 任务是指在 Lakehouse 中通过 Web 端数据开发功能或 CLI、JDBC 连接等方式提交的 SQL 查询任务。

-# Lakehouse对象命名规则
-
-在Lakehouse中，为了确保元数据（如数据库、表、视图、用户等）的命名一致性和可读性，避免潜在的问题，我们制定了一套命名规则。本文档将详细介绍这些规则，帮助您更好地理解和使用Lakehouse。
-
-## 标识符类型
-
-Lakehouse支持以下类型的标识符命名：
-
-* **常规标识符**：不需要引号，但必须符合特定的命名规则。
-* **双引号标识符**：需要使用双引号（"）包围起来，可以对关键字进行转译。
-* **反引号标识符**：需要使用反引号（\`）包围起来，可以包含任何字符，但不能包含反引号本身。默认是反引号，可以通过设置切换为双引号（set `cz.sql.double.quoted.identifiers=true`）。
-
-## 命名规则
-
-### 常规标识符的命名规范
-
-1. **开头字符**：标识符必须以字母（包括大写A-Z、小写a-z）或下划线（"\_"）作为起始字符。不允许以数字或其他特殊字符开始。
-2. **字符组成**：标识符中只能包含字母、下划线和十进制数字（0-9）。不允许使用其他特殊字符和关键字，如连字符（-）、空格或其他非字母数字字符。
-3. **大小写敏感性**：虽然在创建时可以指定大小写，但元数据在存储时会被解析为小写字符。在Lakehouse中，所有对象的名称都是不区分大小写的。这意味着，"MyTable"和"mytable"会被视为相同的标识符。
-4. **语言限制**：不支持中文字符
-5. **长度限制**： 长度为1～256个字符，WORKSPACE NAME长度限制3～28个字符
-
-以下是几个合法的标识符示例：
-
-```SQL
-my_table
-table1
-table_2
-```
-
-### 反引号标识符
-
-如果在对象命名时加上反引号，则遵循以下规则：
-
-* 允许用户使用关键字。
-* 列名允许特殊字符、中文等。
-
-对于需要使用关键字命名的标识符名称，可以使用双引号或反引号将其包围，例如：
-
-```SQL
--- 允许数字
-create schema `123`;
--- 使用关键字作为对象的命名
-create schema `select`;
--- 列名使用关键字作为对象的命名
-create table my_table(`中文` string)
-```
-
-请注意，反引号都可以用来包围标识符，但在某些情况下，它们的行为可能不同。通常，建议只在必要时才使用反引号。
-
-### 双引号标识符
-
-在SQL的ANSI/ISO标准中，双引号中的标识符（分隔标识符）允许用户使用关键字。Lakehouse也可以兼容此行为。开启后，双引号为分隔符标识符，通过设置`cz.sql.double.quoted.identifiers=true`当前只支持会话级别开启。需要注意的是，如果开启双引号为分隔符标识符后，Lakehouse将不再把双引号括起来的数据认为是一个字符串类型。
-
-```SQL
-"[ ... ]"
-```
-
-**注意事项**
-
-* 如果使用双引号标识符创建对象，则在查询或任何其他SQL语句中引用该对象时，如果是关键字必须完全按照创建时指定标识符，包含双引号。不包含双引号可能会导致错误。
-
-  ```SQL
-   --需要使用关键字作为对象的命名
-   create schema "select"
-  ```
-
-# 各个对象的命名规范

-# ClickZetta Travel：数据迁移与SQL转译工具
-
-## 简介
-
-ClickZetta Travel 是由云器研发团队精心打造并开源的一款工具，旨在帮助用户轻松实现从其他数据系统向 ClickZetta Lakehouse 的数据迁移。它提供了一系列强大的功能，包括：
-- 将其他 SQL 方言转译为 ClickZetta Lakehouse 兼容的 SQL。
-- 在源数据系统和 ClickZetta Lakehouse 上分别执行 SQL 并对比结果集。
-- 易于使用的 Web UI，提供直观的操作界面。
-- 命令行工具，支持批量 SQL 迁移。
-
-## 安装与启动
-
-### 安装步骤
-
-1. 确保已安装 Docker。
-2. 通过以下命令获取 ClickZetta Travel 的 Docker 镜像：
-
-```shell
-# 获取镜像
-docker pull clickzetta/clickzetta-travel:dev
-```
-
-3. 在本地创建一个名为 `travel` 的文件夹，用于存放评估所需的配置和数据。
-
-```shell
-mkdir travel
-cd travel
-```
-
-### 启动 Web UI
-
-运行以下命令启动 ClickZetta Travel 的 Web UI：
-
-```shell
-docker run --rm --name cztravel -v $(pwd):/mnt/userdata -p 8501:8501 clickzetta/clickzetta-travel:dev
-```
-
-访问 http://localhost:8501/unify 即可使用 Web UI。
-
-## 使用方法
-
-### Web 页面交互式评估
-
-#### 转译 SQL
-
-1. 在浏览器中打开 http://localhost:8501/unify。
-2. 选择您所使用的数据平台。
-3. 在输入框中填入待转译的 SQL。
-4. 使用快捷键（输入框右下角有提示）或使输入框失去焦点，待输入内容生效后，页面将自动以左右对比的方式展示原始和转译后的 SQL。
-
-![transpile screenshot](travel_screenshot_transpile.png)
-
-#### 执行 SQL 并对比结果
-
-1. 进行数据库连接配置。
-   - 展开页面上的 config template，可以看到配置文件模板。
-   - 将编辑好的配置文件通过页面上传；或直接在宿主机数据目录下新建 conf 子目录，并在此处准备好配置文件，刷新页面后即可从 “select config file” 处选择。
-   - 若配置文件正确，页面将展示连接成功的信息。
-2. 选择校验方式，并点击 Validate 按钮运行 SQL 并校验结果集。
-   - Basic verification：基于有限的基础统计信息校验。
-   - Multidimensional verification：基于丰富的统计信息校验。
-   - Line by line verification：逐行校验。
-
-![validate screenshot](travel_screenshot_validate.png)
-
-### 命令行批量评估
-
-收集待评估的 SQL 语句，将其以一个或多个文件的形式存放到数据目录。当一个文件内包含多个 SQL 语句时，语句间需以分号（;）分隔。
-
-```shell
-# 进入 docker 的命令行环境
-docker exec -it cztravel /bin/bash
-# 切换到数据目录
-cd /mnt/userdata
-```
-
-命令行环境中提供的批量评估命令为 `travel`。该工具：
-- 接受一个或多个内容为以分号分隔的 SQL 的文件。
-- 识别并拆分、编号输入文件中的 SQL 语句，将其转译为 ClickZetta Lakehouse SQL，并在 Lakehouse 上尝试执行这些语句。
-- 产出数据目录，包括评估摘要以及运行数据。运行数据包括执行成功的 SQL 语句、无法转译的 SQL 语句以及智能分类过的执行失败的 SQL 语句。
-- 通过 `travel --help` 可以获取最新的帮助信息。
-
-示例：
-```shell
-root@bce68cf855b8:/mnt/userdata#> travel -c conf/cz_conf.json batch-0906.sql

-# 分区
-
-分区是一种通过在写入时将相似的行分组在一起来加快查询速度的方法。使用分区可以实现数据裁剪，优化查询。查询表时通过WHERE子句指定所需查询的分区，避免全表扫描，提高处理效率，降低计算资源消耗。
-
-## Lakehouse分区实现
-
-Lakehouse的分区类似于Apache Iceberg的[隐藏分区](https://iceberg.apache.org/docs/latest/partitioning/#icebergs-hidden-partitioning)。为了便于理解，我们参考Apache Iceberg的分区概念来介绍Lakehouse分区。
-Apache Iceberg是一个开源的表格格式，Apache Iceberg支持两种分区方式：标识分区和转换分区。
-
-* 标识分区：将表的一个或多个列作为分区键，根据列的值将数据划分为不同的分区。通过获取列值并选择性地对其进行转换来生成分区值
-* 转换分区：将表的一个或多个列经过某种转换函数后作为分区键，根据转换后的值将数据划分为不同的分区。例如，如果表有一个timestamp列，可以使用`years(timestamp)`函数将数据按照从1970年到现在的多少年，不能直接使用TIMESTAMP类型作为分区列,需要使用生成列转换为整数类型(如
-years, months, days)
-
-分区信息和数据文件的路径存储在元数据中。这样做的好处是可以在不影响数据的情况下修改分区策略，也可以隐藏分区信息，不需要在写SQL时指定分区条件。同时分区数量没有限制，因为数据就是分区。
-
-Lakehouse兼容了一部分Apache Iceberg的转换分区函数。但是Apache Iceberg的year、month、day、hour转换分区和数据库中的常用日期函数名称冲突，因此在Lakehouse中的转换分区为years、months、days、hours。以下是Lakehouse支持的分区转换函数：
-
-|                           |                                   |                                                         |      |
-| ------------------------- | --------------------------------- | ------------------------------------------------------- | ---- |
-| 分区函数名称                    | 描述                                | 源类型                                                     | 结果类型 |
-| bucket(numBuckets, colName) | 值的散列值，对N取模                        | int, long, decimal, date, timestamp\_ltz, string binary | int  |
-| truncate(colName,W)       | 值截断到宽度W                           | int, long, decimal, string                              | 源类型  |
-| years                     | 提取日期或时间戳的年份，以1970年为基准             | date, timestamp, timestamptz                            | int  |
-| months                    | 提取日期或时间戳的月份，以1970-01-01为基准        | date, timestamp, timestamptz                            | int  |
-| days                      | 提取日期或时间戳的天数，以1970-01-01为基准        | date, timestamp, timestamptz                            | int  |
-| hours                     | 提取时间戳的小时数，以1970-01-01 00:00:00为基准 | timestamp, timestamptz                                  | int  |

-## Lakehouse分区语法
-
-### 介绍
-
-Lakehouse是基于Apache Iceberg实现的[隐藏分区](https://iceberg.apache.org/docs/latest/partitioning/#icebergs-hidden-partitioning)，为了兼容大多数习惯使用Hive语法的用户，Lakehouse在语法层面实现了一些语法糖。**特别需要注意的是，Apache Hive要求分区列位于列定义的末尾，但Apache Iceberg没有这种强制要求。因此，如果按照原来的Hive方式加列，可能会将列加到最后一个位置，所以加列时必须指定位置。**比如Apache Iceberg在创建分区时语法为如下
-
-```SQL
-CREATE TABLE prod.db.sample (
-id bigint,
-category string,
-data string
-)
-PARTITIONED BY(category)
-```
-
-Hive的语法必须这样
-
-```SQL
-CREATE TABLE prod.db.sample (
-id bigint,
-data string)
-PARTITIONED BY(category string)
-```
-
-Lakehouse做了兼容，既支持Iceberg语法也支持Hive语法。分区字段和类型写在PARTITIONED BY语句中。
-
-### 支持的语法
-
-lakehouse兼容了Hive的分区语法，支持以下几种分区操作：
-
-* Insert into…partition：向表的一个或多个分区中插入数据，如果分区不存在，则自动创建分区，因为分区就是数据。partition子句可以省略，数据会自动根据列的顺序进行映射，但要求分区列和表中对应列的位置必须一致。而在Hive中您必须指定partition子句
-
-* Insert overwrite…partition：覆盖表的一个或多个分区中的数据，如果分区不存在，则自动创建分区。
-  * partition子句可以省略，数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。
-
-  * overwrite行为遵循Hive的原则，如果指定分区且为静态值，则是静态覆盖，即只覆盖指定的分区；如果指定分区且为动态值，或者不指定分区，则是动态覆盖，即覆盖所有匹配的分区。如果表中分区是转换分区，partition子句不支持指定转换函数，可以直接使用insert overwrite table插入数据。
-
-  * ```SQL
-    INSERT OVERWRITE [TABLE] table_name 
-    --partition关键字可选
-    [ PARTITION partition_spec] 
-    [ column_list ]
-    VALUES(value [,...])| select_statement
-    --如果指定PARTITION关键字时partition_spec必选
-    partition_spec ::=
-        partition_col_name = partition_col_val [ , ... ] | partition_col_name
-    ```
-
-* Truncate partition：清空表的一个或多个分区中的数据。但在Hive中会保留分区值，Lakehouse中则不会保留，因为Lakehouse的partition是数据
-
-  * ```SQL
-    TRUNCATE [TABLE] table_name [PARTITION partition_spec];
-    --partition_spec解释
-    partition_spec::=
-      partition_column = partition_col_value, partition_column = partition_col_value, ...)
-    ```
-
-* Drop partition：删除表的一个或多个分区。
-
-  * ```SQL
-    ALTER TABLE table_name DROP [IF EXISTS] PARTITION 
-    partition_spec[, PARTITION partition_spec, ...]
-    ```
-
-* Rename partition:目前您可以直接update更新数据即可
-
-  * ```SQL
-     update sales set order_date='2023-02-02' where order_date= '2023-02-01';
-    ```
-
-* Show partition:建议使用SQL，select distinct进行统计，如`select distinct pt from table_pt;`
-
-### 支持的分区数据类型
-
-
-| 数据类型                     | 是否支持 |

-| TINYINT                  | 支持   |
-| SMALLINT                 | 支持   |
-| INT                      | 支持   |
-| BIGINT                   | 支持   |
-| STRING                   | 支持   |
-| CHAR(n)                  | 支持   |
-| VARCHAR(n)               | 支持   |
-| BOOLEAN                  | 支持   |
-| BINARY                   | 不支持  |
-| FLOAT                    | 不支持  |
-| DOUBLE                   | 不支持  |
-| DECIMAL(precision,scale) | 不支持  |
-| TIMESTAMP\_LTZ           | 不支持  |
-| INTERVAL（时间间隔类型）         | 不支持  |
-| ARRAY                    | 不支持  |
-| MAP                      | 不支持  |
-| STRUCT                   | 不支持  |
-
-### 写入分区
-
-* Insert into…partition：向表的一个或多个分区中插入数据，如果分区不存在，则自动创建分区，因为分区就是数据。partition子句可以省略，数据会自动根据列的顺序进行映射，但要求分区列和表中对应列的位置必须一致。在Hive中您必须指定partition子句
-
-* Insert overwrite…partition：覆盖表的一个或多个分区中的数据，如果分区不存在，则自动创建分区。partition子句可以省略，数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。overwrite行为遵循Hive的原则，如果指定分区且为静态值，则是静态覆盖，即只覆盖指定的分区；如果指定分区且为动态值，或者不指定分区，则是动态覆盖，即覆盖所有匹配的分区。如果表中分区是转换分区，partition子句不支持指定转换函数，可以直接使用insert overwrite table插入数据。
-
-  * ```SQL
-    INSERT OVERWRITE [TABLE] table_name 
-    --partition关键字可选
-    [ PARTITION partition_spec] 
-    [ column_list ]
-    VALUES(value [,...])| select_statement
-    --如果指定PARTITION关键字时partition_spec必选
-    partition_spec ::=
-        partition_col_name = partition_col_val [ , ... ] | partition_col_name
-    ```
-
-**注意**：
-执行写入分区时单个任务目前限制2048个分区，超出此限制将会报错：`The count of dynamic partitions exceeds the maximum number 2048`。插入之前建议您先统计分区的数量如：`select count(distinct pt) from table`。如果您确实有这么多分区可以分批次导入，lakehouse的分区总数没有限制，会在单个任务限制。如果您的数据量较小，建议可以不用设置cluster key和partition key。建议单分区和cluster key的数据量在百MB到GB级别。例如，Parquet格式文件压缩后128MB。

-# 分区
-
-分区是一种通过在写入时将相似的行分组在一起来加快查询速度的方法。使用分区可以达到数据裁剪，优化查询。查询表时通过WHERE子句查询指定所需查询的分区，避免全表扫描，提高处理效率，降低计算资源
-
-## Lakehouse分区实现
-
-Lakehouse的分区类似于Apache Iceberg的[隐藏分区](https://iceberg.apache.org/docs/latest/partitioning/#icebergs-hidden-partitioning)。为了便于理解，我们参考Apache Iceberg的分区概念来介绍Lakehouse分区。
-Apache Iceberg是一个开源的表格格式，Apache Iceberg支持两种分区方法：标识分区和转换分区。
-
-* 标识分区：将表的一个或多个列作为分区键，根据列的值将数据划分为不同的分区。通过获取列值并选择性地对其进行转换来生成分区值
-* 转换分区：将表的一个或多个列经过某种转换函数后作为分区键，根据转换后的值将数据划分为不同的分区。例如，如果表有一个timestamp列，可以使用`years(timestamp)`函数将数据按照从1970年到现在的多少年。
-
-分区信息和数据文件的路径存储在元数据中。这样做的好处是可以在不影响数据的情况下修改分区策略，也可以隐藏分区信息，不需要在写SQL时指定分区条件。同时分区数量没有限制，因为数据就是分区。
-
-lakehouse兼容了一部分的Apache Iceberg的转化换分区函数。但是Apache Iceberg的year、month、day、hour转化分区和数据库中的常用日期函数名称冲突，因此在Lakehouse中的转化分区为years、months、days、hours。以下是lakehouse支持的分区转化函数：
-
-|                           |                                   |                                                         |      |
-| ------------------------- | --------------------------------- | ------------------------------------------------------- | ---- |
-| 分区函数名称                    | 描述                                | 源类型                                                     | 结果类型 |
-| bucket(numbucket,colNmae) | 值的散列值，对N取模                        | int, long, decimal, date, timestamp\_ltz, string binary | int  |
-| truncate(colName,W)       | 值截断到宽度W                           | int, long, decimal, string                              | 源类型  |
-| years                     | 提取日期或时间戳的年份，以1970年为基准             | date, timestamp, timestamptz                            | int  |
-| months                    | 提取日期或时间戳的月份，以1970-01-01为基准        | date, timestamp, timestamptz                            | int  |
-| days                      | 提取日期或时间戳的天数，以1970-01-01为基准        | date, timestamp, timestamptz                            | int  |
-| hours                     | 提取时间戳的小时数，以1970-01-01 00:00:00为基准 | timestamp, timestamptz                                  | int  |

-## Lakehouse分区语法
-
-### 介绍
-
-Lakehouse的分区为了兼容大多数习惯使用hive语法的用户，Lakehouse在语法层面实现了一些语法糖。**特别注意的是Apache Hive要求分区列是最后一个位置，但是在Apache Iceberg则没有这种强制要求，因此加列的时候特别注意按照原来hive方式加列可能会将列加到最后一个位置，所以加列的时候必须指定位置**。比如Apache Iceberg在创建分区时语法为如下
-
-```SQL
-CREATE TABLE prod.db.sample (
-id bigint,
-category string，
-data string,
-)
-PARTITIONED BY(category)
-```
-
-hive的语法必须这样
-
-```SQL
-CREATE TABLE prod.db.sample (
-id bigint,
-data string)
-PARTITIONED BY(category string)
-```
-
-lakehouse做了兼容即支持iceberg语法也支持hive语法，分区字段和类型写在PARTITIONED BY语句中。
-
-### 支持的语法
-
-lakehouse兼容了Hive的分区语法，支持以下几种分区操作：
-
-* Insert into…partition：向表的一个或多个分区中插入数据，如果分区不存在，则自动创建分区，因为分区就是数据。partition子句可以省略， 数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。在hive中您必须指定parition子句
-
-* Insert overwrite…partition：覆盖表的一个或多个分区中的数据，如果分区不存在，则自动创建分区。partition子句可以省略，数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。overwrite行为遵循Hive的原则，如果指定分区且为静态值，则是静态覆盖，即只覆盖指定的分区；如果指定分区且为动态值，或者不指定分区，则是动态覆盖，即覆盖所有匹配的分区。如果表中分区是转换分区，partition子句不支持指定转换函数，可以直接使用insert overwrite table插入数据。
-
-  * ```SQL
-    INSERT OVERWRITE [TABLE] table_name 
-    --partition关键字可选
-    [ PARTITION partition_spec] 
-    [ column_list ]
-    VALUES(value [,...])| select_statement
-    --如果指定PARTITION关键字时partition_spec必选
-    partition_spec ::=
-        partition_col_name = partition_col_val [ , ... ] | partition_col_name
-    ```
-
-* Truncate partition：清空表的一个或多个分区中的数据。但在hive中会保留分区值，Lakehouse中则不会保留，因为Lakehouse的parition是数据
-
-  * ```SQL
-    TRUNCATE [TABLE] table_name [PARTITION partition_spec];
-    --partition_spec解释
-    partition_spec::=
-      partition_column = partition_col_value, partition_column = partition_col_value, ...)
-    ```
-
-* Drop partition：删除表的一个或多个分区。
-
-  * ```SQL
-    ALTER TABLE table_name DROP [IF EXISTS] PARTITION 
-    partition_spec[, PARTITION partition_spec, ...]
-    ```
-
-* Rename partition:目前您可以直接update更新数据即可
-
-  * ```SQL
-     update sales set order_date='2023-02-02' where order_date= '2023-02-01';
-    ```
-
-* Show partition:建议使用SQL，select distinct进行统计，如`select distinct pt from table_pt;`
-

-
-### 写入分区
-
-* Insert into…partition：向表的一个或多个分区中插入数据，如果分区不存在，则自动创建分区，因为分区就是数据。partition子句可以省略， 数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。在hive中您必须指定parition子句
-
-* Insert overwrite…partition：覆盖表的一个或多个分区中的数据，如果分区不存在，则自动创建分区。partition子句可以省略，数据会自动根据列的顺序映射要求必须分区列和表的位置应映射一致。overwrite行为遵循Hive的原则，如果指定分区且为静态值，则是静态覆盖，即只覆盖指定的分区；如果指定分区且为动态值，或者不指定分区，则是动态覆盖，即覆盖所有匹配的分区。如果表中分区是转换分区，partition子句不支持指定转换函数，可以直接使用insert overwrite table插入数据。
-
-  * ```SQL
-    INSERT OVERWRITE [TABLE] table_name 
-    --partition关键字可选
-    [ PARTITION partition_spec] 
-    [ column_list ]
-    VALUES(value [,...])| select_statement
-    --如果指定PARTITION关键字时partition_spec必选
-    partition_spec ::=
-        partition_col_name = partition_col_val [ , ... ] | partition_col_name
-    ```
-
-**注意**：
-执行写入分区时单个任务目前限制2048个分区，超出此限制将会报错：`The count of dynamic partitions exceeds the maximum number 2048`。插入之前建议您先统计分区的数量如：`select count(distinct pt) from table`。如果您确实有这么多分区可以分批次导入，lakehouse的分区总数没有限制，会在单个任务限制。如果您的数据量较小建议可以不用设置cluster key和partiiton key。建议单分区和cluster key在百MB到GB级别。例如parquet格式文件压缩后128MB

-## QA问题
-
-问题一：为什么相同租户下，有的workspace\_dev可以新建、修改、删除、启停集群，有的不可以。
-
-答：本文档中列出的预设角色功能权限限制，在新版本（Release 2025.03.05）中生效。若用户的角色配置是在此版本前设定，则权限按照旧版本逻辑执行。如在使用中遇到细节问题，请联系我们的技术支持同学进行解答。

-# 最佳实践：使用 Pipe 高效接入 kafka 数据
-# 快速验证 kafka 参数
-
-在云器 Lakehouse 中，使用 Kafka pipe 可以非常容易构建分钟级近实时数据集成链路。在开始之前，需要确认三件事：
-
-1. 网络连通性
-2. Kafka bootstrap 地址、端口和 topic
-3. （可选）认证方式及相关参数
-
-上述目的可以通过直接运行形如 `select * from read_kafka()` 查询的方式来快速验证。
-
-这里是一个无认证的 kafka 接入样例：
-
-```SQL
-SELECT *
-FROM read_kafka(
-  'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
-  'topic-name',   -- topic
-  '',             -- reserved
-  'test',         -- kafka group id, for keeping read position
-  '', '', '', '', -- reserved
-  'raw',          -- key format, can only be raw
-  'raw',          -- value format, can only be raw
-  0,
-  MAP(
-    'kafka.security.protocol','PLAINTEXT',
-    'kafka.auto.offset.reset','latest'
-  )
-)
-LIMIT 10;
-```
-
-> read\_kafka 函数参数众多，但是实际需要填写的只有 bootstrap 地址、topic 和 group id。探查阶段我们使用 test 作为 group id
-
-这是一个读取 SASL\_PLAINTEXT 认证方式的样例（pipe 仅支持 PLAINTEXT 和 SASL\_PLAINTEXT）：
-
-```SQL
-SELECT *
-FROM read_kafka(
-  'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
-  'topic-name',   -- topic
-  '',             -- reserved
-  'test',         -- kafka group id, for keeping read position
-  '', '', '', '', -- reserved
-  'raw',          -- key format, can only be raw
-  'raw',          -- value format, can only be raw
-  0,
-  MAP(
-    'kafka.security.protocol','SASL_PLAINTEXT',
-    'kafka.sasl.mechanism','PLAIN',
-    'kafka.sasl.username','<username>',
-    'kafka.sasl.password','<password>',
-    'kafka.auto.offset.reset','latest'
-  )
-)
-LIMIT 10;
-```
-
-如果参数配置无误，执行上述 SQL 将获得 10 行样例数据
-

-
-# 小批量读取数据确认 schema 并创建目标表
-
-kafka 数据中的 key 和 value 都是 binary 类型。通常我们更关心的是 value 的内容。如果其中本来存放就是字符串，可以在 select 的时候 cast 成 string 来快速探查其中内容。
-
-```sql
-SELECT key::string, value::string
-FROM read_kafka(
-  'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
-  'topic-name',   -- topic
-  '',             -- reserved
-  'test',         -- kafka group id, for keeping read position
-  '', '', '', '', -- reserved
-  'raw',          -- key format, can only be raw
-  'raw',          -- value format, can only be raw
-  0,
-  MAP(
-    'kafka.security.protocol','PLAINTEXT',
-    'kafka.auto.offset.reset','latest'
-  )
-)
-LIMIT 10;
-```

-
-点击「复制」获取样例数据并探查，可见 value 大体是个 JSON，但是 JSON 中有些 string field 还是个完整的 JSON，看起来还不止一层，结构略复杂：

-```
-
-调整 select 语句，使用 parse\_json 将 value 字段和其中的 event 展开：
-
-```SQL
-SELECT
-    parse_json(j['event']::string) as event,
-    j['op_type']::string as op_type,
-    j['datasource_id']::string as datasource_id,
-    j['database_name']::string as database_name,
-    j['schema_name']::string as schema_name,
-    j['table_name']::string as table_name,
-    timestamp_millis(j['event_ts']::bigint) as event_ts,
-    j['event_seq']::string as event_seq,
-    timestamp_millis(j['server_ts']::bigint) as server_ts,
-    j['server_seq']::bigint as server_seq
-FROM (
-    SELECT parse_json(value::string) as j
-    FROM read_kafka(
-    'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap

-        'kafka.auto.offset.reset','latest'
-    )
-    )
-    LIMIT 10
-);
-
-```
-
-运行发现 event 中的 statements 仍然是 JSON。
-
-![](/.topwrite/assets/image_1760681703861.png)
-
-继续调整 select 语句，直到将所有内容为 JSON 的字符串 parse 完毕再落表，避免后续查询重复计算 parse\_json。
-
-```SQL
-SELECT
-    parse_json(j['event']::string) as event,
-    parse_json(parse_json(j['event']::string)['statements']::string) as statements,
-    j['op_type']::string as op_type,

-    j['server_seq']::bigint as server_seq
-FROM (
-    SELECT parse_json(value::string) as j
-    FROM read_kafka(
-    'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
-    'topic_name',   -- topic
-    '',             -- reserved

-    MAP(
-        'kafka.security.protocol','PLAINTEXT',
-        'kafka.auto.offset.reset','latest'
-    )
-    )
-    LIMIT 10
-);
-```
-
-根据 select 的探查结果，确定目标表结构，并建表：
-
-```SQL
-CREATE TABLE ods_commit_log (
-    event json,
-    statements json,
-    op_type string,
-    datasource_id string,
-    database_name string,
-    schema_name string,
-    table_name string,
-    event_ts timestamp,
-    event_seq string,
-    server_ts timestamp,
-    server_seq bigint,
-    __kafka_timestamp__ timestamp,
-    pt_date string generated always as (date_format(`server_ts`, 'yyyyMMdd')) stored
-) PARTITIONED BY (pt_date)
-PROPERTIES(
-    'data_lifecycle'='14'
-); 
-```
-
-> 通常 kafka 流入的数据以 append only 的日志表居多，因此基于业务时间戳 server\_ts 增加了自动生成列 pt\_date 作为分区列，并配合 table properties 中的 data\_lifecycle 来对表数据量进行控制
-
-> 表 DDL 中增加了 \_\_kafka\_timestamp\_\_ 字段，记录数据流过 kafka 的时间，这列在业务上鲜有价值，但是可以在数据延迟发生时用于原因诊断，我们建议保留
-
-至此，我们已经完成了 kafka 数据和目标表结构的对齐。
-
-# 正式创建 Pipe
-
-接下来，从已有的探查 select 语句作为基础，构建 Pipe DDL。Pipe 对实际上是对 `COPY INTO <table> FROM (SELECT ... FROM READ_KAFKA(...))` 的封装，同时增加指定计算资源、调度频率等工程参数。
-
-考虑到 Kafka 数据通常为流式进入，如果我们需要目标表的新鲜度为 1 分钟，即 pipe 每 60 秒调度一个 `COPY INTO` 作业，那么建议给 pipe 划分一个专用的 GP 集群。
-
-```sql
-CREATE VCLUSTER pipe_ods_commit_log 
-    VCLUSTER_TYPE = GENERAL 
-    VCLUSTER_SIZE = 1
-;
-```
-
->先不用纠结这个 GP vcluster 的大小，我们可以在后续的调整阶段根据作业实际执行情况再作调整。
-
->单独划分集群的原因之一是过高的数据新鲜度（比如小于 5 分钟）会使集群几乎没有空闲的可能，成为事实上的常驻资源消耗。因此通常不应该把 pipe 跑在很大的集群上导致资源浪费。但是反过来看，如果 kafka 流入的数据量较小，也没有必要给每个 pipe 都划分单独的集群。此时可以使一系列 pipe 共享一个常驻集群以节省资源。
-
-Pipe DDL 如下:
-
-1. 去掉 `select ... from read_kafka(...)` 字句里的 `limit 10`
-2. group id 从 test 更换为线上准备正式使用的名字，如 sub2cz
-3. （可选）使用 RESET\_KAFKA\_GROUP\_OFFSETS 参数指定读取 kafka 的时间点（否则会按照 kafka.auto.offset.reset 的设置从 latest 读起），需要使用毫秒单位的 epoch。
-
-```sql
-CREATE PIPE pipe_ods_commit_log 
-    VIRTUAL_CLUSTER = 'pipe_ods_commit_log' 
-    BATCH_INTERVAL_IN_SECONDS = '60'
-    RESET_KAFKA_GROUP_OFFSETS = '1740931200000' -- epoch in millis of 2025-03-03 00:00:00
-AS COPY INTO ods_commit_log FROM (
-SELECT
-    parse_json(j['event']::string) as event,
-    parse_json(parse_json(j['event']::string)['statements']::string) as statements,
-    j['op_type']::string as op_type,
-    j['datasource_id']::string as datasource_id,
-    j['database_name']::string as database_name,
-    j['schema_name']::string as schema_name,
-    j['table_name']::string as table_name,
-    timestamp_millis(j['event_ts']::bigint) as event_ts,
-    j['event_seq']::string as event_seq,
-    timestamp_millis(j['server_ts']::bigint) as server_ts,
-    j['server_seq']::bigint as server_seq,
-    `timestamp` as __kafka_timestamp__
-FROM (
-    SELECT `timestamp`, parse_json(value::string) as j
-    FROM read_kafka(
-    'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
-    'topic_name',   -- topic
-    '',             -- reserved
-    'sub2cz',       -- kafka group id, for keeping read position
-    '', '', '', '', -- reserved
-    'raw',          -- key format, can only be raw
-    'raw',          -- value format, can only be raw
-    0,
-    MAP(
-        'kafka.security.protocol','PLAINTEXT',
-        'cz.kafka.fetch.retry.enable','true', 
-        'cz.kafka.fetch.retry.times','20',
-        'cz.kafka.fetch.retry.intervalMs','2000'
-    )
-)));
-```
-
->这里我们在 read\_kafka 的参数中补充了 cz.kafka.fetch.retry.enable、cz.kafka.fetch.retry.times、cz.kafka.fetch.retry.intervalMs 三个参数，指定函数在遇到读 kafka 失败时的重试策略。这样有助于减少生产作业的告警和人工介入次数。
-
-Pipe 创建后，会自动开始运行。在 Studio 依次点击「计算」-「集群」-「PIPE\_ODS\_COMMIT\_LOG」-「作业」，我们可以通过这个页面快速检查由 pipe 提交作业的运行情况。
-
-当多个 pipe 复用一个 VCluster 时，也可以用 query\_tag 在 studio 的「计算」-「作业历史」页面或 InformationSchema 的 job\_history 表快速查询指定 pipe 的作业运行情况。由 pipe 提交的作业，其 query\_tag 为 pipe.\<workspace\_name>.\<schema\_name>.\<pipe\_name> 的形式：
-
-```sql
-select query_tag, job_id, status, start_time, end_time, execution_time, input_bytes, output_bytes, rows_produced
-from information_schema.job_history
-where pt_date>='yyyy-MM-dd' -- eg. 2025-03-03
-and query_tag = 'pipe.<workspace_name>.<schema_name>.<pipe_name>' -- eg. 'pipe.quick_start.public.pipe_ods_commit_log'
-order by start_time desc;
-```
-
-# 大数据量及资源调优
-
-优化 Kafka pipe 在生产环境稳定运行，就是在数据新鲜度要求的周期内（BATCH\_INTERVAL\_IN\_SECONDS ），用最小的资源配置（VCluster），恰好完成流入数据的计算和落盘（生产中应保留一定算力冗余，以确保在数据量波动、集群升级作业 failover 等情况发生时，pipe 能够较快追平数据，通常建议保留一倍的冗余度）。用本文的例子通俗的讲，就是至少要能够在 30 秒左右，处理完这 1 分钟由 kafka 流入的数据。
-
-Pipe 的默认设置在大多数情况下工作良好。但如果接入的 kafka 数据量特别大，则应根据实际情况调整参数，如下图红色文字标注部分：
-
-![](/.topwrite/assets/image_1760681949544.png)
-
-
-
-确认当前的 pipe 是否积压，可以通过多次执行`desc pipe extended` 查看 pipe\_latency 行的 timeLag（kafka 点位和当前时间的差距，单位毫秒）是否在持续增加。当数据新鲜度为 60 秒，且算力冗余为一倍时，timeLag 应该在0\~90 秒之间波动（如果完全不做冗余，波动应该在 0\~120 秒之间），当 timeLag 会超过上限且在几个周期之后持续上涨，则 pipe 会产生积压。
-
-## 确认 kafka 的消息峰值（增大 `BATCH_SIZE_PER_KAFKA_PARTITION` 参数）
-
-为了防止 pipe 在启动时读取过多数据导致作业超大作业出现，pipe 会限制每次从 partition 中读取的数据条数，通过 `BATCH_SIZE_PER_KAFKA_PARTITION` 控制，默认 50000。当 kafka 每周期每 partition 的消息峰值超过此值时，应该在 CREATE PIPE 时人工指定该参数。通常建议设置该值为峰值的 2 倍。当 pipe 已经在运行中，也可以通过`alter pipe <pipe_name> set BATCH_SIZE_PER_KAFKA_PARTITION=<event_number>;` 来动态调整该值。
-
-如图所示，虽然 pipe 的分钟作业只要不到 30 秒即可执行完成，但此时 desc pipe extended 指示 timeTag 可能在持续增大。
-
-![](/.topwrite/assets/image_1760681973997.png)
-
-点击作业进入作业详情页，可以看到这是一个 10 个 partition 的 kafka topic。即使设置 BATCH\_SIZE\_PER\_KAFKA\_PARTITION 为 100000，然没有完整读取一个周期所有数据，需要继续增大。
-
-![](/.topwrite/assets/image_1760681981294.png)
-
-最终，通过不断增大该值并持续观察 timeLag（生产使用时通常应该预先知晓 kafka per partition 的峰值，直接设置就好），确定该值为 500000 时，pipe 的消费速度较快可以追平 kafka。
-
->与直接 `select ... read_kafka(...)` 不同，通过 pipe 生成的 `copy into`作业，可以看到由 pipe 管理的，记录在 kafka group id 中的点位信息，很容易识别读取的 kafka topic 有多少个 partition，以及各个 partition 的实际点位值。
-
-## 调整 VCluster Size
-
-默认情况下，Pipe 启动的 `copy into` 作业，task 数量和 kafka topic partition 数量一致，即每个 task 读取一个 partition。当 VCluster Size 较小时，作业的 task 可能需要多轮才能完全运行结束，从而显著拉长作业运行时间。
-
-因此，当需要作业尽快结束时，应保证 VCluster 的允许的 task 并发度 >= partition 数，使所有 task 一轮运行完。
-
-下图一个使用 128CRU VCluster（1024core）的 pipe 作业，消费 1200 个 partition 的 kafka topic， 需要运行两轮，第一轮 1024 个 task，剩余的 176 个 task 第二轮，显著拉长了运行时间。此时将 VCluster 设置为 150CRU 为宜（1200core）。
-
-![](/.topwrite/assets/image_1760681994525.png)
-
-## 切分 kafka 数据以利用更多计算资源（设置 COPY\_JOB\_HINT）
-
-当 kafka 数据量很大但 partition 数较少，或 pipe 落表前的计算逻辑较为复杂使得单个 task 不足以在周期要求内完成单个 partition 数据量计算时，可以考虑通过设置 COPY\_JOB\_HINT 来对 task 进行进一步拆分，并配合更多计算资源来实现加速的效果。
-
-COPY\_JOB\_HINT 是一个 JSON 形式表达的复合参数，人工切分 kafka 数据需要联合使用一下两个 key：
-
-1. "cz.sql.split.kafka.strategy":"size"默认为 "simple"，即每个 partition 划分一个 task。须更改为 "size"，意为按照条数来切分 task。
-2. "cz.mapper.kafka.message.size":"200000"指示 pipe 多少 event 划分一个 task，默认值 1000000，当 "cz.sql.split.kafka.strategy" 为 "size" 时生效。
-
-可以通过 `alter pipe pipe_ods_commit_log set COPY_JOB_HINT = '{"cz.sql.split.kafka.strategy":"size","cz.mapper.kafka.message.size":"200000"}';` 随时调整 pipe 的切分 task 策略。
-
->COPY\_JOB\_HINT 是 JSON 形式的复合参数，通过 alter pipe 设置时是覆盖行为，需要小心设置某些 key 时意外丢失了之前设置的其他 key。此时可以通过 desc pipe extended 在 properties 行的 copy\_job\_hint 中获取完整设置，并基于此进行修改。
-
-在对参数调整完毕之后，我们建议将同步改动对应的 Pipe DDL，防止后续流程重建/迁移导致参数遗漏。
-
-```SQL
-CREATE VCLUSTER pipe_ods_commit_log 
-    VCLUSTER_TYPE = GENERAL 
-    VCLUSTER_SIZE = 150
-;
-
-CREATE PIPE pipe_ods_commit_log
-    VIRTUAL_CLUSTER = 'PIPE_ODS_COMMIT_LOG' 
-    BATCH_INTERVAL_IN_SECONDS = '60'
-    BATCH_SIZE_PER_KAFKA_PARTITION = 2000000
-    RESET_KAFKA_GROUP_OFFSETS = '1740931200000' -- epoch in millis of 2025-03-03 00:00:00
-    COPY_JOB_HINT = '{"cz.sql.split.kafka.strategy":"size","cz.mapper.kafka.message.size":"200000"}' -- to accelerate load
-AS COPY INTO ods_commit_log FROM 
-...
-```
-
-# 更改 Pipe SQL 逻辑
-
-Pipe 允许在 `copy into` 和 `read_kafka` 之间做比较复杂的计算。当计算逻辑发生变化，或目标表 schema 发生变化时（典型场景是增加列），需要对已有的 pipe 定义进行修改。
-
-简言之，pipe ddl 的修改，是保持 read\_kafka 参数不变的情况下，删除并重建 pipe。
-
-例如我们需要修改 pipe\_ods\_commit\_log，在目标表 event 字段中去掉 statments 的内容（因为和 statments 字段冗余了一份存储），则可以按照如下步骤进行操作：
-
-1. 删除当前运行的 pipe
-
-```SQL
-drop pipe pipe_ods_commit_log;
-```
-
->对已有 pipe  drop pipe 和 alter pipe，会被 pipe 当前正在运行的作业阻塞，直到作业结束后才会返回，可能会需要些时间。
-
-2. 重建 pipe（注意去掉 RESET\_KAFKA\_GROUP\_OFFSETS 参数）
-
-```sql
-CREATE PIPE pipe_ods_commit_log 
-    VIRTUAL_CLUSTER = 'pipe_ods_commit_log' 
-    BATCH_INTERVAL_IN_SECONDS = '60'
-    BATCH_SIZE_PER_KAFKA_PARTITION = 2000000
-    -- RESET_KAFKA_GROUP_OFFSETS = '1740931200000' -- epoch in millis of 2025-03-03 00:00:00
-    COPY_JOB_HINT = '{"cz.sql.split.kafka.strategy":"size","cz.mapper.kafka.message.size":"200000"}' -- to accelerate load
-AS COPY INTO ods_commit_log FROM (
-SELECT
-    remove_json(parse_json(j['event']::string), '$.statements') as event,
-    parse_json(parse_json(j['event']::string)['statements']::string) as statements,
-    j['op_type']::string as op_type,
-    j['datasource_id']::string as datasource_id,
-    j['database_name']::string as database_name,
-    j['schema_name']::string as schema_name,
-    j['table_name']::string as table_name,
-    timestamp_millis(j['event_ts']::bigint) as event_ts,
-    j['event_seq']::string as event_seq,
-    timestamp_millis(j['server_ts']::bigint) as server_ts,
-    j['server_seq']::bigint as server_seq,
-    `timestamp` as __kafka_timestamp__
-FROM (
-    SELECT `timestamp`, parse_json(value::string) as j
-    FROM read_kafka(
-    'kafka-bootstrap-1:9092,kafka-bootstrap-2:9092,kafka-bootstrap-3:9092', -- bootstrap
-    'topic_name',   -- topic
-    '',             -- reserved
-    'sub2cz',       -- kafka group id, for keeping read position
-    '', '', '', '', -- reserved
-    'raw',          -- key format, can only be raw
-    'raw',          -- value format, can only be raw
-    0,
-    MAP(
-        'kafka.security.protocol','PLAINTEXT',
-        'cz.kafka.fetch.retry.enable','true', 
-        'cz.kafka.fetch.retry.times','20',
-        'cz.kafka.fetch.retry.intervalMs','2000'
-    )
-)));
-```
-
->Pipe 使用 kafka group 来记录读取的点位，因此只要使用相同的 kafka 集群、topic 及 group id，即使重建 pipe，点位也不会丢失，可以实现「断点续传」的效果。
-
-但是 RESET\_KAFKA\_GROUP\_OFFSETS 会强制改写 group id 中记录的点位，需要谨慎使用。

-# 使用 Table Stream 和 Pipe 将 Kafka 数据导入 Lakehouse
-
-## 一、背景介绍
-
-在大数据处理领域，将 Kafka 中的流数据高效地导入 Lakehouse（数据湖仓）是一个常见的需求。云器科技提供了强大的 Table Stream 和 Pipe 功能，使得这一过程变得更加简便和高效。本文将详细介绍如何使用 Table Stream 和 Pipe 将 Kafka 数据导入 Lakehouse，包括创建 Kafka 外部表和 Kafka Table Stream 的完整过程。
-
-## 二、操作步骤
-
-### 创建 Kafka 外部表
-
-在使用 Table Stream 和 Pipe 之前，我们需要先创建一个与[ Kafka 集成的外部表](create-kafka-external.md)，用于访问 Kafka 中的数据。
-
-```sql
-CREATE STORAGE CONNECTION pipe_kafka
- TYPE kafka 
-BOOTSTRAP_SERVERS = ['47.00.08.62:9092'] 
-SECURITY_PROTOCOL = 'PLAINTEXT';
-
-CREATE EXTERNAL TABLE external_table_kafka (   
- key_column binary,   
- value_column binary NOT NULL)
-USING kafka
-OPTIONS (   'group_id' = 'external_table_lh',    'topics' = 'my_topic')
-CONNECTION pipe_kafka;
-```
-
-
-
-### 创建 Table Stream
-
-在 Kafka 外部表上[创建一个 Table Stream](create-table-stream.md)，以便能够实时地捕获 Kafka 中的数据变化。
-
-```sql
-CREATE TABLE STREAM kafka_table_stream_pipe1 
-ON TABLE external_table_kafka
-WITH PROPERTIES (
-    'table_stream_mode' = 'append_only'
-
-);
-```
-
-* `kafka_table_stream_pipe1`：Table Stream 的名称。
-* `ON TABLE external_table_kafka`：指定基于之前创建的 Kafka 外部表创建 Table Stream。
-* `table_stream_mode='append_only'`：指定 Table Stream 的模式为仅追加，意味着只会捕获新增的数据行。
-
-
-
-创建完成后，可以通过以下查询来验证 Table Stream 中的数据：
-
-```sql
-SELECT CAST(value AS STRING) FROM kafka_table_stream_pipe1;
-```
-
-此查询将 Table Stream 中的 `value` 字段转换为字符串类型并返回，方便后续处理。
-
-### 创建目标表
-
-接下来，我们需要创建一个目标表，用于存储从 Kafka 导入的数据。
-
-```sql
-CREATE TABLE kafka_sink_table_1 (
-    a TIMESTAMP,
-    b STRING
-);
-```
-
-* `kafka_sink_table_1`：目标表的名称。
-* `a TIMESTAMP`：第一个字段，用于存储时间戳类型的数据。
-* `b STRING`：第二个字段，用于存储字符串类型的数据。
-
-### 创建 Pipe
-
-最后，使用 Pipe 将 Table Stream 中的数据持续导入到目标表中。
-
-```sql
-CREATE PIPE kafka_pipe_stream
-VIRTUAL_CLUSTER = 'test_alter'
-AS
-COPY INTO kafka_sink_table_1
-FROM (
-    SELECT CURRENT_TIMESTAMP(), CAST(value AS STRING) FROM kafka_table_stream_pipe1
-);
-```
-
-* `kafka_pipe_stream`：Pipe 的名称。
-* `VIRTUAL_CLUSTER = 'test_alter'`：指定使用的虚拟集群为 名称，
-* `COPY INTO kafka_sink_table_1`：将数据复制到目标表 `kafka_sink_table_1` 中。
-* `SELECT CURRENT_TIMESTAMP(), CAST(value AS STRING) FROM kafka_table_stream_pipe1`：从 Table Stream 中选择数据，将当前时间戳和转换为字符串的 `value` 字段作为目标表的两列数据。
-
-其他可设置的属性
-- `INITIAL_DELAY_IN_SECONDS`:首个作业调度延迟，选填项（默认 0 秒）
-- `BATCH_INTERVAL_IN_SECONDS`：（可选）设置批处理间隔时间，默认值为60秒。
-- `BATCH_SIZE_PER_KAFKA_PARTITION`：（可选）设置每个Kafka分区的批处理大小，默认值为500,000条。
-- `MAX_SKIP_BATCH_COUNT_ON_ERROR`：（可选）设置在出错时跳过的批次的最大重试次数，默认值为30。
-- `RESET_KAFKA_GROUP_OFFSETS`：（可选）设置启动pipe时Kafka的初始点位,不支持修改。可选值为`latest`、`earliest`、`none`、`valid`、`${TIMESTAMP\_MILLISECONDS}`
-    - 'none' 默认无操作
-    - 'valid' 检查 group 中的当前点位是否过期，将过期的 partition 点位重置到当前的 earliest 
-    - 'earliest' 重置到当前 earliest
-    - 'latest' 重置到当前 latest    
-    - '${TIMESTAMP\_MILLISECONDS}' 重置到毫秒时间戳对应点位，如 '1737789688000'（2025-01-25 15:21:28）
-
-## 三、验证结果
-
-可以通过查询目标表来验证数据是否成功导入：
-
-```sql
-SELECT * FROM kafka_sink_table_1;
-```
-
-同时，可以查看 Pipe 的运行状态，确保其正常工作：
-
-```sql
-SHOW PIPES;
-```
-
-此命令将列出所有已创建的 Pipe 及其状态信息，包括是否在运行、上次运行时间等。
-## 四、状态监控与管理
-### 查看Kafka消费延迟
-通过 DESC PIPE 命令。如下面的pipe_latency中的json字符串。
-    - lastConsumeTimestamp：上一次消费的点位
-    - offsetLag：Kafka数据得堆积量
-    - timeLag：消费延迟，计算为当前时间减去上一次消费的点位。当Kafka消费异常时值为-1

-
-### 查看Pipe运行历史
-由于每次都是Pipe下发copy执行，你可以在作业历史中查看所有操作。通过[作业历史](<web-job-history.md>)中的query_tag来筛选，所有的pipe执行的copy作业都会在query_tag打上标签，格式为`pipe.``workspace_name``.schema_name.pipe_name`，方便追踪和管理。
-
-### 停止和启动Pipe
-- 暂停Pipe
-```
-ALTER PIPE pipe_name SET PIPE_EXECUTION_PAUSED = true;
-```
-- 启动Pipe
-```
-ALTER PIPE pipe_name SET PIPE_EXECUTION_PAUSED = false;
-```
-
-### 修改Pipe属性
-您可以修改 PIPE 的属性，但每次只能修改一个属性。如果需要修改多个属性，则需要多次执行 `ALTER` 命令。以下是可修改的属性及其语法：
-
-```SQL
-ALTER PIPE pipe_name SET 
-    [VIRTUAL_CLUSTER = 'virtual_cluster_name'],
-    [BATCH_INTERVAL_IN_SECONDS=''],
-    [BATCH_SIZE_PER_KAFKA_PARTITION=''],
-    [MAX_SKIP_BATCH_COUNT_ON_ERROR=''],
-    [COPY_JOB_HINT='']
-```
-案例
-```
---修改计算集群
-ALTER PIPE pipe_name SET VIRTUAL_CLUSTER = 'default'
---设置COPY_JOB_HINT
-ALTER PIPE pipe_name SET COPY_JOB_HINT='{"cz.mapper.kafka.message.size": "2000000"}'
-
-```
-**注意**
-- 不支持修改COPY语句逻辑，如果您需要修改请删除Pipe重新创建
-- 当你修改 Pipe 的 `COPY_JOB_HINT` 时，新的设置会覆盖原有的 hints。因此，如果你的 Pipe 中已经存在某些 hints，例如 `{"cz.sql.split.kafka.strategy":"size"}`，当你再次添加新的 hints 时，必须将所有需要的 hints 一起设置，否则原有的 hints 会被新设置的 hints 覆盖。多个参数之间使用逗号分隔

-# 使用Pipe自动采集Kafka数据
-
-## 概述
-
-Pipe 是 Lakehouse 提供的**持续数据摄取**解决方案，专门用于从 Kafka 自动、持续地将数据导入到 Lakehouse 表中。Pipe 会创建持久的消费者组，保持消费位置，并按照设定的调度策略持续运行。
-
-## Kafka Pipe语法
-
-```SQL
--- 从Kafka创建Pipe的语法
-CREATE PIPE [ IF NOT EXISTS ] <pipe_name>
-    VIRTUAL_CLUSTER = 'virtual_cluster_name'
-    [INITIAL_DELAY_IN_SECONDS='']
-    [BATCH_INTERVAL_IN_SECONDS='']
-    [BATCH_SIZE_PER_KAFKA_PARTITION='']
-    [MAX_SKIP_BATCH_COUNT_ON_ERROR='']
-    [RESET_KAFKA_GROUP_OFFSETS='']
-    [COPY_JOB_HINT='']
-AS <copy_statement>;
-```
-
-* `<pipe_name>`：Pipe 对象的名称，用于管理和监控
-* `VIRTUAL_CLUSTER`：指定执行 Pipe 任务的虚拟集群名称
-* `INITIAL_DELAY_IN_SECONDS`:首个作业调度延迟，选填项（默认 0 秒）
-* `BATCH_INTERVAL_IN_SECONDS`：（可选）设置批处理间隔时间，默认值为60秒。
-* `BATCH_SIZE_PER_KAFKA_PARTITION`：（可选）设置每个Kafka分区的批处理大小，默认值为500,000条。
-* `MAX_SKIP_BATCH_COUNT_ON_ERROR`：（可选）设置在出错时跳过的批次的最大重试次数，默认值为30。
-* `RESET_KAFKA_GROUP_OFFSETS`：（可选）控制 Pipe 启动时从 Kafka 的哪个位置开始消费数据只支持启动时设置，如果不设置此参数且消费者组无历史位置信息，将使用 Kafka 的 [auto.offset.reset](https://kafka.apache.org/documentation/#consumerconfigs_auto.offset.reset) 配置（默认为 `latest`）。支持的可选值如下
-  * 'none'无操作，如果设置为none则会使用[auto.offset.reset](https://kafka.apache.org/documentation/#consumerconfigs_auto.offset.reset)
-  * 'valid' 检查 group 中的当前点位是否过期，将过期的 partition 点位重置到当前的 earliest
-  * 'earliest' 重置到当前 earliest
-  * 'latest' 重置到当前 latest
-  * '${TIMESTAMP\_MILLISECONDS}' 重置到毫秒时间戳对应点位，如 '1737789688000'（2025-01-25 15:21:28）
-
-## 在 Pipe 中使用 READ\_KAFKA
-
-如果您想临时探查则可以使READ_KAFKA函数参考文档[READ_KAFKA函数](<sql_functions/table_functions/read_kafka.md>)，在 Pipe 的 COPY 语句中使用 `READ_KAFKA` 时，有以下**重要差异**：
-
-### 参数传递规则
-
-```sql
--- Pipe 中的 READ_KAFKA 语法
-read_kafka (
-    'bootstrap_servers',     -- 必填：Kafka 集群地址
-    'topic',                 -- 必填：Topic 名称
-    '',                      -- 必填：Topic 模式（暂不支持，填空字符串）
-    'group_id',              -- 必填：持久消费者组 ID
-    '',                      -- 留空：起始位置由 Pipe 自动管理
-    '',                      -- 留空：结束位置由 Pipe 自动管理  
-    '',                      -- 留空：起始时间戳由 Pipe 自动管理
-    '',                      -- 留空：结束时间戳由 Pipe 自动管理
-    'raw',                   -- Key 格式
-    'raw',                   -- Value 格式
-    0,                       -- 最大错误数
-    map()                    -- Kafka 配置参数
-)
-```
-### 关键区别
-
-| 特性     | READ\_KAFKA 函数（独立使用）     | READ\_KAFKA（在 Pipe 中） |
-| ------ | ------------------------ | --------------------- |
-| 消费者组   | 临时，执行完即销毁                | 持久，保持消费位置状态           |
-| 位置管理   | 手动指定 starting\_offsets 等 | Pipe 自动管理，位置参数必须留空    |
-| 执行方式   | 一次性查询                    | 持续调度执行                |
-| 默认起始位置 | earliest（探查历史数据）         | latest（处理新数据）         |
-
-### 最佳实践
-参考使用 [Pipe 高效接入 kafka 数据](<pipe-kafka-bestpractice-1.md>)

-### 查看Pipe运行历史
-
-由于每次都是Pipe下发copy执行，你可以在作业历史中查看所有操作。通过[作业历史](web-job-history.md)中的query\_tag来筛选，所有的pipe执行的copy作业都会在query\_tag打上标签，格式为`pipe.``workspace_name``.schema_name.pipe_name`，方便追踪和管理。
-
-### 停止和启动Pipe
-
-* 暂停Pipe
-
-```
-ALTER PIPE pipe_name SET PIPE_EXECUTION_PAUSED = true;
-```
-
-* 启动Pipe
-
-```
-ALTER PIPE pipe_name SET PIPE_EXECUTION_PAUSED = false;
-```
-
-### 修改Pipe属性
-
-您可以修改 PIPE 的属性，但每次只能修改一个属性。如果需要修改多个属性，则需要多次执行 `ALTER` 命令。以下是可修改的属性及其语法：
-
-```SQL
-ALTER PIPE pipe_name SET 
-   [VIRTUAL_CLUSTER = 'virtual_cluster_name'],
-   [BATCH_INTERVAL_IN_SECONDS=''],
-   [BATCH_SIZE_PER_KAFKA_PARTITION=''],
-   [MAX_SKIP_BATCH_COUNT_ON_ERROR=''],
-   [COPY_JOB_HINT='']
-```
-
-案例
-
-```
---修改计算集群
-ALTER PIPE pipe_name SET VIRTUAL_CLUSTER = 'default'
---设置COPY_JOB_HINT
-ALTER PIPE pipe_name SET COPY_JOB_HINT='{"cz.mapper.kafka.message.size": "2000000"}'
-
-```
-
-**注意**
-
-* 不支持修改 COPY 语句逻辑，如果您需要修改，请删除 Pipe 后重新创建。
-* 当你修改 Pipe 的 `COPY_JOB_HINT` 时，新的设置会覆盖原有的 hints。因此，如果你的 Pipe 中已经存在某些 hints，例如 `{"cz.sql.split.kafka.strategy":"size"}`，当你再次添加新的 hints 时，必须将所有需要的 hints 一起设置，否则原有的 hints 会被新设置的 hints 覆盖。多个参数之间使用逗号分隔

-# 概述
-
-Pipe 是 Lakehouse 平台中的一项强大数据导入功能，它允许用户以固定频率直接从对象存储中读取数据并导入到 Lakehouse。通过实现文件检测机制，Pipe 支持以微批处理方式加载文件，使得用户能够迅速访问最新数据。特别适合需要实时或近实时数据处理的场景。
-
-## Pipe 工作原理
-
-1. **文件检测**：
-
-   1. **EVENT\_NOTIFICATION\_MODE**：需要开通消息服务，利用阿里云消息服务通知Lakehouse新文件的上传，目前只支持阿里云OSS和AWS S3。
-   2. **LIST\_PURGE模式**：定期扫描目录，同步未记录的文件，并在同步后删除原文件。
-
-2. **COPY 语句**：定义数据文件的源位置和目标表，支持多种文件格式。
-
-3. **自动化加载**：自动检测新文件并执行COPY语句。
-
-4. **避免导入重复机制**：为了避免重复导入，load\_history函数记录了当前表的copy导入历史文件。Pipe在执行时会根据load\_history表名和导入文件名称去重，确保不会重复导入已有的文件。如果需要导入已记录的文件，可以手动执行copy命令。load\_history记录目前会保留7天。
-
-5. **Pipe导入作业历史**：由于每次都是Pipe下发copy执行，你可以在作业历史中查看所有操作。通过作业历史中的query\_tag来筛选，所有的pipe执行的copy作业都会在query\_tag打上标签，格式为`pipe.``workspace_name``.schema_name.pipe_name`，方便追踪和管理。
-
-## 使用场景
-
-* **实时数据同步**：当你的数据存储在对象存储中，且需要频繁同步以及时获取最新数据。
-* **成本优化**：在对象存储上进行数据导入导出可以避免产生网络公网流量费用。特别是在相同region下，可以指定对象存储为内网传输，进一步降低成本。
-
-## 注意事项
-
-* 使用EVENT\_NOTIFICATION\_MODE时，需要使用role arn授权方式创建存储连接。
-* LIST\_PURGE模式支持密钥和role arn两种授权方式。
-* **文件大小推荐**：gzip 压缩文件建议在 50MB。CSV、PARQUET 未压缩文件建议在 128MB 到 256MB 之间。
-* **数据加载顺序**：**数据加载无法保证严格有序**。
-* **Pipe 延迟**:Pipe加载时间受多种因素影响，包括文件格式、大小和COPY语句的复杂性。
-* **Pipe 与 Volume 对应关系**： 每个 Pipe 需对应独立的 Volume，不可复用。

-- PIPE中的COPY语句不支持files/regexp/subdirectory参数

-
-根据加载文件时使用的计算资源计费。
-## PIPE语法
-```SQL
--- 从对象存储创建Pipe的语法
-CREATE PIPE [ IF NOT EXISTS ] <pipe_name>
-    VIRTUAL_CLUSTER = 'virtual_cluster_name'
-    INGEST_MODE='LIST_PURGE'|'EVENT_NOTIFICATION'
-    [COPY_JOB_HINT='']
-AS <copy_statement>;
-```
-- `<pipe_name>`：您要创建的Pipe对象的名称。
-- `VIRTUAL_CLUSTER`：指定虚拟集群的名称。
-- `INGEST_MODE`：设置为`LIST_PURGE`或`EVENT_NOTIFICATION`，以确定数据导入模式。
-- `COPY_JOB_HINT`：可选，Lakehouse保留参数
-- copy_statement：`<copy_statement>` 支持 中的中的文件参数都支持。当设置 `ON_ERROR=CONTINUE|ABORT` 参数时，可控制数据加载过程中遇到错误时的处理策略，且添加该参数后会返回导入文件列表：
-    * `CONTINUE`：跳过错误行，继续加载后续数据。适用于容忍部分错误，且要求最大限度完成数据加载的场景。目前，可忽略的错误仅限于文件不格式匹配的情况，例如命令中指定为 zip 压缩格式，而文件中存在 zstd 压缩格式。
-    * `ABORT`：立即终止整个`COPY`操作。适用于数据质量要求严格，任何错误都需要人工介入检查的场景。
-
-
-## 支持的文件格式
-
-参考[COPY INTO导入](copy-into-table.md)。
-
-## 使用PIPE加载案例
-
-### 使用扫描文件模式
-
-**具体使用步骤**
-
-步骤 1: 创建 connection 和 volume
-
-```SQL
---创建连接用来连接对象存储
-CREATE STORAGE CONNECTION if not exists my_connection_exnet
-    TYPE OSS
-    ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com'
-    ACCESS_KEY = 'LTAI5tMmbq1Ty1xxxxxxxxx'
-    SECRET_KEY = '0d7Ap1VBuFTzNg7gxxxxxxxxxxxx'
-    COMMENT = 'OSS public endpoint';
-
---创建volume, 用于映射对象存储目录
-CREATE EXTERNAL VOLUME pipe_volume
-    location 'oss://ossmy/autoloader/pipe/'
-    using connection my_connection_exnet
-    directory = (
-        enable=true,
-        auto_refresh=true
-    )
-    recursive=true;
-    
-```
-
-步骤 2: 单独执行copy命令看是否可以导入成功
-
-```SQL
-copy into pipe_purge_mode from volume pipe_volume(id int,col string) 
-using csv OPTIONS(
-  'header'='false'
-) ;
-```
-
-步骤 3: 使用上面的语句构建pipe对象
-
-```SQL
-create pipe volume_pipe_list_purge
-  VIRTUAL_CLUSTER = 'default'
-  --执行获取最新文件使用扫描文件模式
-  INGEST_MODE = 'LIST_PURGE'
-  as
-copy into pipe_purge_mode from volume pipe_volume(id int,col string) 
-using csv OPTIONS(
-  'header'='false'
-)
---必须添加purge参数导入成功后删除数据 
-purge=true
-;
-```
-
-步骤 4: 查看pipe执行历史和已经导入的文件
-
-* 查看pipe copy作业执行情况
-
-通过作业历史中的query\_tag来筛选,所有的pipe执行的copy作业都会在query\_tag打上标签:格式为pipe.worksapce\_name.schema\_name.pipe\_name
-
-* 查看copy作业导入的历史文件
-
-```SQL
-select * from load_history('schema_name.table_name');
-```
-
-### 使用消息服务通知模式（只支持阿里云OSS和AWS S3）
-
-步骤 1: 开通阿里云消息服务 (MNS)
-
-1. 在阿里云控制台中开通消息服务 MNS。
-2. 配置 MNS 监听要同步的 OSS (Object Storage Service) 文件夹。[具体参考文档](https://help.aliyun.com/zh/mns/user-guide/create-a-rule-to-generate-oss-event-notifications?spm=a2c4g.11186623.0.i14)
-
-步骤 2: 授权 Lakehouse 读取 OSS
-具体方式参考使用role arn方式[阿里云存储连接创建](aliyun_storage_connection.md)授权 Lakehouse 读取对应 OSS Bucket 的权限。
-
-步骤 3: 授权 MNS 给 Lakehouse
-
-```
- 在阿里云 RAM 控制台中，将 `AliyunMNSFullAccess` 权限授权给步骤二中的 Role，步骤二中案例为CzUDFRole
-```
-
-![](.topwrite/assets/image_1722602785678.png)
-
-步骤 4: 创建 Storage Connection
-
-```SQL
-CREATE STORAGE CONNECTION my_connection_exnet_role
-    TYPE oss
-    REGION = 'cn-hangzhou'  -- 根据 OSS 所在的区域选择
-    ROLE_ARN = 'acs:ram::...:role/czudfrole'  -- 替换为你的 Role ARN
-    ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com';  -- 根据 OSS 所在的区域选择 Endpoint
-```
-
-步骤 5: 创建 Volume
-
-```SQL
-CREATE EXTERNAL VOLUME my_volume_exnet_role
-    LOCATION 'oss://function-compute-my1/autoloader'  -- 替换为 OSS Bucket 的路径
-    USING connection my_connection_exnet_role
-    DIRECTORY = (
-        enable = TRUE,
-        auto_refresh = TRUE
-    )
-    RECURSIVE = TRUE;
-```
-
-步骤 6: 创建 Pipe
-
-```SQL
-CREATE PIPE my_pipe
-VIRTUAL_CLUSTER='TEST_VC'
-ALICLOUD_MNS_QUEUE = 'lakehouse-oss-event-queue'  -- 使用创建的 MNS 队列
-AS
-COPY INTO pipe_log_json FROM (
-    SELECT parse_json(col) json_col
-    FROM volume my_volume_exnet_role(col string)
-    USING csv
-    OPTIONS ('header' = 'false', 'sep' = '\001', 'quote' = '\0')
-);
-```

-
-### 查看Pipe运行历史
-由于每次都是Pipe下发copy执行，你可以在作业历史中查看所有操作。通过[作业历史](<web-job-history.md>)中的query_tag来筛选，所有的pipe执行的copy作业都会在query_tag打上标签，格式为`pipe.``workspace_name``.schema_name.pipe_name`，方便追踪和管理。
-
-### 停止和启动Pipe
-- 暂停Pipe
-```
-ALTER PIPE pipe_name SET PIPE_EXECUTION_PAUSED = true;
-```
-- 启动Pipe
-```
-ALTER PIPE pipe_name SET PIPE_EXECUTION_PAUSED = false
-```
-
-### 修改Pipe属性
-您可以修改 PIPE 的属性，但每次只能修改一个属性。如果需要修改多个属性，则需要多次执行 `ALTER` 命令。以下是可修改的属性及其语法：
-
-```SQL
-ALTER PIPE pipe_name SET 
-   [VIRTUAL_CLUSTER = 'virtual_cluster_name']
-   [BATCH_INTERVAL_IN_SECONDS='']
-   [BATCH_SIZE_PER_KAFKA_PARTITION='']
-   [MAX_SKIP_BATCH_COUNT_ON_ERROR='']
-   [RESET_KAFKA_GROUP_OFFSETS='']
-   [COPY_JOB_HINT='']
-```
-案例
-```
---修改计算集群
-ALTER PIPE pipe_name SET VIRTUAL_CLUSTER = 'default'
---设置COPY_JOB_HINT
-ALTER PIPE pipe_name SET COPY_JOB_HINT='{"cz.mapper.kafka.message.size": "2000000"}'

-# 使用Pipe持续导入数据
-
->【预览发布】本功能当前处于公开预览发布阶段。
-
-## 概述
-
-Pipe 管道是云器 Lakehouse 用于流式数据采集的对象类型。使用 Pipe 可以持续增量地采集流式数据（如来自 Kafka），简化流式数据导入流程。
-
-Pipe 管道在定义时使用 COPY 命令表达读取外部数据源并写入目标表的语义。与单独的 COPY 命令的主要区别在于，Pipe 将自动持续调度 COPY 任务，维护和管理数据源的读取位置，持续不断地从数据源增量导入数据。
-
-使用 Pipe 进行流式数据自动导入的总体逻辑示意如下：
-
-![Pipe流式数据导入逻辑示意图](![](.topwrite/assets/image_1718767758845.png =541)
-
-## 数据源支持
-
-Pipe 管道提供了对数据源新变化数据的持续采集能力，当前数据源包括：
-
-* Kafka 数据源
-* 对象存储（如阿里云 OSS）
-
-## 管理使用Pipe
-
-Lakehouse 提供了一组操作命令用于管理 Pipe 管道：
-
-* `CREATE PIPE`
-* `DESC PIPE`
-* `SHOW PIPES`
-* `DROP PIPE`
-
-### 创建Pipe对象
-
-#### 创建Pipe对象读取Kafka数据源
-
-可使用SQL命令创建Pipe对象，语法如下：
-
-```SQL
-CREATE PIPE [ IF NOT EXISTS ] <name>
-  VIRTUAL_CLUSTER = '<virtual_cluster_name>'
-  [ BATCH_INTERVAL_IN_SECONDS = '<number>' ]
-  [ BATCH_SIZE_PER_KAFKA_PARTITION = '<number>' ]
-  [ COMMENT '<string_literal>' ]
-  AS <copy_statement>
-```
-
-参数说明：
-
-* `VIRTUAL_CLUSTER`：Pipe 提交 COPY 作业所用的 VC。必填项。
-* `BATCH_INTERVAL_IN_SECONDS`：作业生成周期。可选参数，默认 60 秒。
-* `BATCH_SIZE_PER_KAFKA_PARTITION`：作业最大单分区消息数。可选参数，默认 50 万。
-* `COMMENT`：添加注释。可选参数。
-* `COPY_STATEMENT`：使用 `COPY INTO` <table> 将数据导入到目标表。
-
-  * 对于 Kafka 数据源，在 SELECT 语句中将使用 `read_kafka` 表值函数读取 Kafka 消息数据。函数的参数说明请查看 `read_kafka` 函数说明。
-
-#### 创建Pipe读取对象存储数据源
-
-读取对象存储需要创建 VOLUME，同时需要开通阿里云消息服务。消息服务用于向 Pipe 发送对象存储事件，以触发 Pipe 执行。
-
-```SQL
---创建pipe,其中ALICLOUD_MNS_QUEUE使用，刚刚创建的云消息服务mns队列lakehouse-oss-event-queue
-CREATE PIPE [ IF NOT EXISTS ] <name>
-  VIRTUAL_CLUSTER = '<virtual_cluster_name>'
-ALICLOUD_MNS_QUEUE = 'MNSQUEUE'
-as
-AS <copy_statement>
-```
-
-参数说明：
-
-* VIRTUAL_CLUSTER：Pipe 提交 COPY 作业所用的 VC。必填项。
-* `ALICLOUD_MNS_QUEUE`：消息队列名称。消息服务 MNS 可以将对象存储指定资源上产生的事件以消息的方式主动推送到指定的接收端。Pipe 接收到消息队列事件后触发执行，获取哪些文件是新增文件，然后触发 `COPY` 命令将数据导入到表中。
-
-### 查看Pipe列表及对象详情
-
-当前您可以使用 SQL 命令查看 Pipe 列表及对象详情。
-
-* 使用 `SHOW PIPES` 命令查看 Pipe 对象列表
-
-```
-列出当前 Schema 下的所有 Pipe
-SHOW PIPES;
--- 列出指定 Schema 下的所有 Pipe
-SHOW PIPES IN SCHEMA schema_name;
--- 列出指定 Workspace 下的所有 Pipe
-SHOW PIPES IN WORKSPACE workspace_name;
-```
-
-**说明**
-
-* `SHOW PIPES`：默认列出当前 Schema 下的 Pipe 对象。
-* `SHOW PIPES IN SCHEMA schema_name`：列出指定 Schema 中的所有 Pipe 对象。
-* `SHOW PIPES IN WORKSPACE workspace_name`：列出指定 Workspace 中的所有 Pipe 对象。
-
-* 使用 `DESC PIPE` 命令查看指定 Pipe 对象详细信息
-
-```SQL
-DESC PIPE <name>;
-```
-
-### 删除Pipe对象
-
-您可以使用 SQL 命令删除 Pipe 对象。
-
-```SQL
-DROP PIPE <name>;
-```
-
-## 约束与限制
-
-* 数据源是 Kafka 时：一个 Pipe 中只能有一个 `read_kafka` 函数。
-* 数据源是对象存储时：一个 Pipe 中只能有一个 Volume 对象。

-
-本文档提供了创建Pipe对象的详细语法，以便自动化地将数据从对象存储或Kafka导入到Lakehouse。Pipe对象是一种强大的工具，可以帮助用户简化数据导入流程，并确保数据的高效流动。
-
-## 从对象存储导入数据
-
-要创建一个Pipe对象以从对象存储导入数据，可以使用以下语法：
-
-```SQL
--- 从对象存储创建Pipe的语法
-CREATE PIPE [ IF NOT EXISTS ] <pipe_name>
-    VIRTUAL_CLUSTER = 'virtual_cluster_name'
-    INGEST_MODE='LIST_PURGE'|'EVENT_NOTIFICATION'
-    [COPY_JOB_HINT='']
-AS <copy_statement>;
-```
-
-* `<pipe_name>`：您要创建的Pipe对象的名称。
-* `VIRTUAL_CLUSTER`：指定虚拟集群的名称。
-* `INGEST_MODE`：设置为`LIST_PURGE`或`EVENT_NOTIFICATION`，以确定数据导入模式。
-* `COPY_JOB_HINT`：可选，Lakehouse保留参数
-- `IGNORE_TMP_FILE`:取值true|false,默认值true。支持过滤点开头和 _temporary 开头的文件或者目录文件参数。如 `s3://my_bucket/a/b/.SUCCESS，oss://my_bucket/a/b/_temporary/`或者`oss://my_bucket/a/b/_temporary_123/`
-- copy_statement：`<copy_statement>` 支持 中的中的文件参数都支持。当设置 `ON_ERROR=CONTINUE|ABORT` 参数时，可控制数据加载过程中遇到错误时的处理策略，且添加该参数后会返回导入文件列表：
-    * `CONTINUE`：跳过错误行，继续加载后续数据。适用于容忍部分错误，且要求最大限度完成数据加载的场景。目前，可忽略的错误仅限于文件不格式匹配的情况，例如命令中指定为 zip 压缩格式，而文件中存在 zstd 压缩格式。
-    * `ABORT`：立即终止整个`COPY`操作。适用于数据质量要求严格，任何错误都需要人工介入检查的场景。
-### 使用限制
-* Pipe 中的 COPY 语句不支持 files、regexp、subdirectory 参数。
-* **Pipe 与 Volume 对应关系**：每个 Pipe 需对应独立的 Volume，不可复用。
-
-
-
-### 使用说明

-```
-- `<pipe_name>`：您要创建的Pipe对象的名称。
-- `VIRTUAL_CLUSTER`：指定虚拟集群的名称。
-- `INITIAL_DELAY_IN_SECONDS`:首个作业调度延迟，选填项（默认 0 秒）
-- `BATCH_INTERVAL_IN_SECONDS`：（可选）设置批处理间隔时间，默认值为60秒。
-- `BATCH_SIZE_PER_KAFKA_PARTITION`：（可选）设置每个Kafka分区的批处理大小，默认值为500,000条。
-- `MAX_SKIP_BATCH_COUNT_ON_ERROR`：（可选）设置在出错时跳过的批次的最大重试次数，默认值为30。
-- `RESET_KAFKA_GROUP_OFFSETS`：（可选）设置启动pipe时Kafka的初始点位，不支持使用Alter修改。可选值为`latest`、`earliest`、`none`、`valid`、`${TIMESTAMP\_MILLISECONDS}`
-    - 'none'：默认无操作。
-    - 'valid'：检查 group 中的当前点位是否过期，将过期的 partition 点位重置到当前的 earliest。
-    - 'earliest'：重置到当前 earliest。
-    - 'latest'：重置到当前 latest。
-    - '${TIMESTAMP\_MILLISECONDS}'：重置到毫秒时间戳对应点位，例如 '1737789688000'（2025-01-25 15:21:28）。

-
-# 查看 Pipe 列表及对象详情
-
-列出指定范围内的所有 Pipe 对象。
-
-```
-列出当前 Schema 下的所有 Pipe
-SHOW PIPES;
--- 列出指定 Schema 下的所有 Pipe
-SHOW PIPES IN SCHEMA schema_name;
--- 列出指定 Workspace 下的所有 Pipe
-SHOW PIPES IN WORKSPACE workspace_name;
-```
-**说明**
-
-* `SHOW PIPES`：默认列出当前 Schema 下的 Pipe 对象。
-* `SHOW PIPES IN SCHEMA schema_name`：列出指定 Schema 中的所有 Pipe 对象。
-* `SHOW PIPES IN WORKSPACE workspace_name`：列出指定 Workspace 中的所有 Pipe 对象。
-
-# 删除Pipe对象
-
-当不再需要某个Pipe对象时，可以使用以下命令删除它。
-
-```SQL
-DROP PIPE <name>;
-```
-
-# 查看Pipe创建语句
-
-```SQL
-SHOW CREATE  PIPE <name>;
-```
-
-# 修改Pipe属性
-
-您可以修改 PIPE 的属性，但每次只能修改一个属性。如果需要修改多个属性，则需要多次执行 `ALTER` 命令。以下是可修改的属性及其语法：
-
-```SQL
-ALTER PIPE pipe_name SET 
-   [VIRTUAL_CLUSTER = 'virtual_cluster_name'],
-    [BATCH_INTERVAL_IN_SECONDS=''],
-    [BATCH_SIZE_PER_KAFKA_PARTITION=''],
-    [MAX_SKIP_BATCH_COUNT_ON_ERROR=''],
-    [COPY_JOB_HINT='']
-```
-
-案例
-
-```
---修改计算集群
-ALTER PIPE pipe_name SET VIRTUAL_CLUSTER = 'default'
---设置COPY_JOB_HINT
-ALTER PIPE pipe_name SET COPY_JOB_HINT='{"cz.mapper.kafka.message.size": "2000000"}'
-
-
-```
-
-#### load_history 函数
-
-**功能描述**：load_history 函数用于查看表的 COPY 作业导入文件历史，保留期为 7 天。同时，Pipe 在执行时会根据 load_history 避免重复导入已有的文件，确保数据的唯一性。
-
-**函数语法**：
-
-```SQL
-load_history('schema_name.table_name')
-```
-
-* **schema\_name.table\_name**：指定要查看导入历史的表名。
-
-**使用案例**：
-
-```SQL
-SELECT * FROM load_history('myschema.mytable');
-```
-
-# 约束与限制
-
-* 数据源是 Kafka 时：一个 Pipe 中只能有一个 `read_kafka` 函数。
-* 数据源是对象存储时：一个 Pipe 中只能有一个 Volume 对象。

-# Python任务使用实践
-
-任务开发模块中提供的Python任务，作为一种轻量级资源容器下的特定任务类型，专为运行Python代码而设计，提供了任务间环境隔离的功能，并具备基础的环境定制能力。本文介绍Python任务的一些使用实践。
-
-^
-
-### 运行环境和定制
-
-Python任务在系统预设的Pod环境中执行，预装的Python版本为Python 3（当前版本为3.9.2，未来可能会更新）。
-
-系统默认镜像中包含了一些常用的依赖包，以支持与云器 Lakehouse 的连接和数据访问，以及对阿里云 OSS 和腾讯云 COS 等对象存储服务的操作。这些依赖包包括但不限于：
-
-* clickzetta-connector
-* clickzetta-sqlalchemy
-* cos-python-sdk-v5
-* numpy
-* oss2
-* pandas
-* six
-* urllib2
-* ...
-
-为了满足特定的运行需求，Pod环境提供了有限的环境定制能力。您可以在 `/home/system_normal` 路径下进行自定义安装。以下是一个示例代码片段，展示了如何在Python环境中安装自定义安装包（第4行和第5行）并使用。请注意，Python任务执行完毕后，Pod环境将会被销毁，因此任何环境定制都不会被保留。
-
-```py
-import subprocess
-import sys
-
-subprocess.check_call([sys.executable, "-m", "pip", "install", "mysql-connector-python","--target", "/home/system_normal", "-i", "https://pypi.tuna.tsinghua.edu.cn/simple"])
-sys.path.append('/home/system_normal')
-
-import mysql.connector
-
-# 创建连接
-connection = mysql.connector.connect(
-    host='127.0.0.1',   # 数据库主机地址
-    user='****',       # 数据库用户名
-    password='***********', # 数据库密码
-    database='demo'  # 需要连接的数据库名称
-)
-
-# 创建游标
-cursor = connection.cursor()
-
-# 执行查询
-query = "show tables"  # 替换为你的 SQL 查询
-cursor.execute(query)
-
-# 获取查询结果
-results = cursor.fetchall()
-print("Query results:")
-for row in results:
-    print(row)
-
-# 关闭游标和连接
-cursor.close()
-connection.close()
-```
-
-^
-
-### 运行资源大小调整
-
-默认情况下，Pod 提供 0.5 个 CPU 核和 512 MB 内存资源。如果需要，您可以在任务的调度配置中通过以下参数调整资源分配：
-
-* `pod.limit.cpu`：设置 CPU 核数。必须是大于 0 的数值，如 1，最高可设置为 4。默认值为 0.5。
-* `pod.limit.memory`：设置内存大小，格式为数值加上单位，如 2G，最高可设置为 8G。默认值为 512M。
-
-  ![](.topwrite/assets/image_1718339259582.png =513)
-
-通过合理配置这些参数，您可以确保 Python 任务拥有足够的资源来满足不同的计算需求，同时避免资源浪费。
-
-^
-
-### 更多使用案例
-
-#### 使用 Python Database API 查询 Lakehouse 数据
-
-```py
-from clickzetta import connect
-
-# 建立连接
-conn = connect(
-    username='your_username',
-    password='your_password',
-    service='region_id.api.clickzetta.com',
-    instance='your_instance',
-    workspace='your_workspace',
-    schema='public',
-    vcluster='default'
-)
-
-# 创建游标对象
-cursor = conn.cursor()
-
-# 执行 SQL 查询
-cursor.execute('SELECT * FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live LIMIT 10;')
-
-# 获取查询结果
-results = cursor.fetchall()
-for row in results:
-    print(row)
-```
-
-^
-
-#### 使用 SQLAlchemy 接口查询 Lakehouse 数据
-
-```py
-from sqlalchemy import create_engine
-from sqlalchemy import text
-
-# 创建 ClickZetta Lakehouse 的 SQLAlchemy 引擎实例
-engine = create_engine(
-    "clickzetta://username:password@instance.api.clickzetta.com/workspace?schema=schema&vcluster=default"
-)
-
-# 执行 SQL 查询
-sql = text("SELECT * FROM ecommerce_events_multicategorystore_live;")
-
-# 使用引擎执行查询
-with engine.connect() as conn:
-    result = conn.execute(sql)
-    for row in result:
-        print(row)
-```
-
-#### 使用 Python 批量上传数据到 Lakehouse
-
-```py
-from clickzetta import connect
-
-conn = connect(
-    username='your_username',
-    password='your_password',
-    service='region_id.api.clickzetta.com',
-    instance='your_instance',
-    workspace='your_workspace',
-    schema='public',
-    vcluster='default'
-)
-
-bulkload_stream = conn.create_bulkload_stream(schema='public', table='bulkload_test')
-
-writer = bulkload_stream.open_writer(0)
-for index in range(1000000):
-    row = writer.create_row()
-    row.set_value('i', index)
-    row.set_value('s', 'Hello')
-    row.set_value('d', 123.456)
-    writer.write(row)
-writer.close()
-
-bulkload_stream.commit()

-# 云器Lakehouse计费说明
-
-## 1. 计费方式概述
-
-云器Lakehouse是基于云原生建设的一体化数据平台，平台会记录你在数据集成、数据分析、存储和网络传输等场景下消耗的资源，并按照计算、存储、网络三种类型，根据服务发生的云平台和地域，向您收取相应的费用。
-
-云器Lakehouse的计费主要基于以下几个方面：
-
-* **计算资源**：计算资源的计费单元为**CRU**\***时**，1CRU\*时代表在每个云平台的每个服务区域以同样的算力运行1小时。你在云器Lakehouse使用同步型、分析型、通用型计算集群所进行数据集成或数据分析，使用Python、Shell脚本处理的任务，以及系统自动处理的自动物化视图（Auto\_MV)、数据压缩、作业任务调度等操作均会产生计算资源的使用。我们会根据实际消耗的算力使用量进行计量计费。
-* **存储资源**：存储资源的计费单元为GiB，根据你在云器Lakehouse上实际使用的存储容量进行计费。以下场景会占用存储容量：
-  1）在Lakehouse中以表、物化视图等形式存储的数据；
-  2）数据表生命周期内已删除但未清理的数据；
-  3）查询结果的缓存。其中第2、第3项当前仅计量，暂免收费。
-* **数据传输**：数据传输的计费单元为GB，根据数据传输的量进行计费。以下场景会产生数据传输费用：通过公网的数据查询，数据查询结果的全量下载，以云器Lakehouse为数据源向其他数据源传输数据。数据传输流量可能通过Internet、跨VPC的网络连接、专线或者其他网络连通方式产生。其中针对Internet网络流量，仅计量从云器Lakehouse流出的数据传输量，上传数据至云器Lakehouse不收费。
-
-## 2. 计费方式
-
-**按需计费**
-
-在云器Lakehouse中，各类资源均是灵活扩展、按需使用的，你只需按照实际使用的资源量进行付费。其中：
-
-**计算资源**计费按秒统计每一台计算集群实例的开机至关机的时间，按照CRU进行计量，并换算成法定货币为单位的账单；
-
-**存储资源**以全天所有数据（包含数据表当前数据、历史版本数据，查询结果缓存等）存储容量的平均值计费；
-
-**网络传输**费用按照实际产生的网络流量计费，其中Internet网络流量费用以流出Lakehouse方向的流量计费。
-
-由于不同云平台、不同区域下，资源的价格不同，计算、存储和网络每单位的单价也会存在差异。具体价格请参考“云器Lakehouse价格表”，以系统内实际账单为准。
-
-你可以通过“管理中心”-“计费账单”页面查看资源使用情况及费用明细。其中计算资源和数据传输费用每小时进行一次计量和扣费，存储资源以全天24小时采样的容量平均值，每天进行一次计量和扣费。
-
-**包年预付费**
-
-云器Lakehouse也可为企业客户提供指定资源规格，按年预付费的计费方式。包年预付费时，计算和存储资源的单价可提供相应折扣。详情请联系云器销售人员。
-
-## 3. 计费原理
-
-### 3.1 计算资源计费
-
-计算资源的计费项包括：通用型计算集群、分析型计算集群、同步型计算集群、调度任务和serverless作业5种。各计费项的计费原理如下：
-
-* **通用型计算集群**
-
-当通用型计算集群启动至“运行中”状态，即开始根据集群的规格大小和实例数，产生对应的CRU消耗，当该计算集群进入“停止中”状态，则停止产生CRU消耗。
-
-^
-
-通用型计算集群的规格及对应的每小时CRU消耗如下：
-
-| **计算集群规格** | **每小时CRU消耗**（CRU\*时） |
-| ---------- | -------------------- |
-| 1          | 1                    |
-| 2          | 2                    |
-| 3          | 3                    |
-| 4          | 4                    |
-| 5          | 5                    |
-| ...        | ...                  |
-| 256        | 256                  |
-
-* **分析型计算集群**
-
-分析型计算集群的计费原理与通用型计算集群相同，从“运行中”状态的开始时间开始计量，直至进入“停止中”状态。
-
-分析型计算集群在规格的基础上，增加了“实例”的弹缩。当通过自动弹缩扩容出1个实例，即会增加一个同等规格计算集群的消耗。
-
-下表为分析型计算集群1到5个实例时，每小时CRU消耗，更多实例数以此类推：
-
-| **计算集群规格** | **1个实例**&#xA;**每小时消耗** | **2个实例**&#xA;**每小时消耗** | **3个实例**&#xA;**每小时消耗** | **4个实例**&#xA;**每小时消耗** | **5个实例**&#xA;**每小时消耗** |
-| ---------- | ---------------------- | ---------------------- | ---------------------- | ---------------------- | ---------------------- |
-| 1          | 1 CRU\*时               | 2 CRU\*时               | 3 CRU\*时               | 4 CRU\*时               | 5 CRU\*时               |
-| 2          | 2 CRU\*时               | 4 CRU\*时               | 6 CRU\*时               | 8 CRU\*时               | 10 CRU\*时              |
-| 4          | 4 CRU\*时               | 8 CRU\*时               | 12 CRU\*时              | 16 CRU\*时              | 20 CRU\*时              |
-| 8          | 8 CRU\*时               | 16 CRU\*时              | 24 CRU\*时              | 32 CRU\*时              | 40 CRU\*时              |
-| 16         | 16 CRU\*时              | 32 CRU\*时              | 48 CRU\*时              | 64 CRU\*时              | 80 CRU\*时              |
-| 32         | 32 CRU\*时              | 64 CRU\*时              | 96 CRU\*时              | 128 CRU\*时             | 160 CRU\*时             |
-| 64         | 64 CRU\*时              | 128 CRU\*时             | 192 CRU\*时             | 256 CRU\*时             | 320 CRU\*时             |
-| 128        | 128 CRU\*时             | 256 CRU\*时             | 384 CRU\*时             | 512 CRU\*时             | 640 CRU\*时             |
-| 256        | 256 CRU\*时             | 512 CRU\*时             | 768 CRU\*时             | 1024 CRU\*时            | 1280 CRU\*时            |
-
-* **同步型计算集群**
-
-同步型计算集群主要用于提交离线集成和实时集成任务。多个集成任务可提交至同1个同步型计算集群中，以复用资源。同步型计算集群的计费原理与通用型计算集群相同，从“运行中”状态的开始时间开始计量，直至进入“停止中”状态。当前“同步型计算集群”处于试运行状态，暂时以同步型计算集群中执行的数据集成作业为单位，分别计入至“离线集成”和“实时集成”两个计费项中。“同步型计算集群”正式运行后，数据集成费用合并至同步型计算集群计费项中。
-
-同步型计算集群的规格及对应的每小时CRU消耗如下：
-
-| **计算集群规格** | **每小时CRU消耗** |
-| ---------- | ------------ |
-| 0.25       | 0.25 CRU\*时  |
-| 0.5        | 0.5 CRU\*时   |
-| 1          | 1 CRU\*时     |
-| 2          | 2 CRU\*时     |
-| 3          | 3 CRU\*时     |
-| 4          | 4 CRU\*时     |
-| 5          | 5 CRU\*时     |
-| ...        | ...          |
-| 256        | 256 CRU\*时   |
-
-* **任务调度**
-
-任务调度包含两个场景：运行python、shell等脚本，以及离线或实时数据集成任务中的作业提交和调度管理。
-
-运行python、shell等脚本时，系统会根据脚本运行的资源配置，启动对应的计算资源。以启动执行脚本的计算资源为开始，脚本执行结束为终止，计量这个时间段内使用的计算资源，以CRU\*时为单位生成计费账单。
-在离线数据集成任务运行时，云器Lakehouse会提供少量计算资源用于作业提交和调度管理，这部分资源会在离线集成任务启动时开始使用（作业排队等待过程中不会消耗），并在离线集成任务进行时持续存在。因此，该计算资源的消耗会被计量，并以CRU\*时为单位生成计费账单。
-在实时数据集成任务运行时，云器Lakehouse会提供少量计算资源用于作业提交和调度管理，这部分资源会在实时集成任务启动时使用，在任务正式运行后结束。在这段时间内的计算资源消耗会被计量，并以CRU\*时为单位生成计费账单。
-
-* **Serverless作业**
-
-Serverless作业指无需用户主动创建计算集群实例，而由云器Lakehouse提供公共计算资源处理客户计算需求的作业统称。包含查询作业调度、数据压缩、自动物化视图等。
-
-### 3.2 存储资源计费
-
-存储费用根据您在Lakehouse平台实际使用的存储容量进行计量计费。当您在Lakehouse数仓中写入数据后，写入的数据及其部分元数据信息即在Lakehouse中占用存储容量。Lakehouse将统计您的数据实际占用的存储用量，于1天之内多次采样，并以当天采样存储容量的平均值，作为当天的存储容量计量数值，进行计量计费。
-
-当你使用Lakehouse的Time Travel功能时，为了保障数据的多版本、可恢复，Lakehouse会自动为您的数据进行多版本备份存储。此时产生的多版本备份数据将产生相应存储费用，以存储容量单价收费。
-
-当你进行SQL查询时，为降低重复查询的计算资源消耗，会对查询结果进行缓存，以存储成本换取计算资源的节省。这部分存储使用会计入“结果缓存（Result Cache）”，以存储容量单价收费。
-
-### 3.3 数据传输计费
-
-当你使用数据集成等功能，批量从Lakehouse通过公网下载、导出数据时，会产生Internet网络传输费用。Internet网络传输以实际产生的传输数据量进行计量，并计算费用。
-
-你从其他数据源通过Internet网络向Lakehouse上传数据产生的网络传输流量，不会产生网络传输费用。
-
-如果你使用了专线、Private Link或其他网络产品实现跨云厂商、跨地域或跨VPC网络打通时，网络打通本身会产生费用。这部分费用根据网络打通方式不同，产生在云器Lakehouse侧的由云器收取，在你的云平台账号中产生的费用由云平台直接收取。
-
-### 3.4 其他云资源计费
-
-云器Lakehouse在进行元数据管理，解析sql语句、生成查询计划、调度和分配查询任务，以及对数据文件进行合并、清理等操作时，均会消耗云资源。云器Lakehouse会对这些云资源的消耗进行计量，当前限时免费。开始收费前1个月将提前通知。

-## 5. 常见场景下的费用示例
-
-**通用型计算集群费用示例**
-
-以阿里云上海企业版服务实例为例：
-
-* 一个规格为2CRU的通用型计算集群，运行1小时，CRU\*时单价为3.5元，该计算集群运行1小时的费用为： 1小时\*2CRU\*3.5元/CRU\*时 = 7元
-* 一个规格为1CRU的通用型计算集群，运行1分20秒，CRU\*时单价为3.5元，该计算集群运行产生的费用为：1.33分钟/60分钟\*1CRU\*3.5元/CRU\*时=0.078元
-* 一个规格为1CRU的通用型计算集群，运行30秒，CRU\*时单价为3.5元，该计算集群运行产生的费用为：0.5分钟/60分钟\*1CRU\*3.5元/CRU\*时=0.029元 。
-
-**分析型计算集群费用示例**
-
-以阿里云上海企业版服务实例为例：
-
-* 一个规格为2CRU的分析型集群，分别以1个实例运行了30分钟，又以2个实例运行了30分钟，当CRU\*时单价为3.5元，该计算集群运行产生的费用为：
-
-  30分钟/60分钟\*1CRU\*1个实例\*3.5元/CRU\*时 + 30分钟/60分钟\*1CRU\*2个实例\*3.5元/CRU\*时 = 1.75元 + 3.5元 = 5.25元
-
-**同步型计算集群价格费用示例**
-
-以阿里云上海企业版服务实例为例：
-
-* 一个规格为2CRU的同步型集群，运行1小时，当CRU\*时单价为3.5元，该计算集群运行1小时的费用为： 1小时\*2CRU\*3.5元/CRU\*时 = 7元
-
-**离线集成任务费用示例**
-
-离线集成任务不单独收费，而是收取任务提交至的同步型计算集群的运行费用。离线集成任务可自动唤起同步型计算集群。一般估算离线集成任务时，可按照：5个单并发的离线集成任务可用满一个规格为0.25的同步型计算集群资源来估算离线集成任务。
-
-* 假设阿里云上海一个企业版服务实例的一个单并发离线集成任务运行10分钟，其消耗的算力约为：1/5 CRU \* 10分钟/60分钟 = 0.033 CRU\*时;
-* 因离线集成任务会唤起同步型计算集群，假设阿里云上海一个企业版服务实例的同步型计算集群的规格为1 CRU，10分钟任务结束后自动关闭，则产生的费用为：1CRU\*10分钟/60分钟\*3.5元/CRU\*时 = 0.58元；
-
-此时该规格为1 CRU的同步型计算集群还未用满，再提交4个单并发离线集成任务，假设均运行10分钟，其产生的费用仍为 0.58元。因此，尽量复用同步型计算集群的资源，同时避免使用过大规格的同步型计算集群能有效节省计算资源费用。
-
-**实时集成任务费用示例**
-
-实时集成任务不单独收费，而是收取任务提交至的同步型计算集群的运行费用。实时集成任务需要将其所在的同步型计算集群一直保持“运行”状态。因此需要选择尽量贴近实时集成任务所需的资源量创建同步型计算集群规格，避免资源浪费。可按照：16个单并发的实时集成任务可用满一个规格为1CRU的同步型计算集群资源来估算。
-
-**Python脚本任务费用示例**
-
-Python脚本任务执行时，会根据任务执行时长和消耗的计算资源进行计费。一般情况下，一个Python脚本执行1小时时，所使用的计算资源为0.125 CRU\*小时。
-
-* 假设阿里云上海一个企业版服务实例的一个Python脚本任务执行时间为10分钟，其产生的费用为：0.125CRU\*时\*10分钟/60分钟\*3.5元/CRU\*时=0.073元。
-
-**存储容量费用示例**
-
-* 假设在阿里云上海一个企业版服务实例的工作空间下，全天的存储容量低点为910GiB，高点1100GiB，全天平均值为1000GiB，则当天存储容量为：1000 GiB \* 0.12元/GiB/月 /30天 = 4元
-
-**网络传输价格示例**
-
-* 假设在阿里云上海一个企业版服务实例下，1小时产生的Internet下行流量为10 GB，则该小时的Internet网络传输费用为：10GB\*0.8元/GB=8元

-# Clickzetta Lakehouse约束属性概述
-
-Clickzetta Lakehouse支持多种约束属性，以满足用户在数据写入、更新和维护过程中的需求。本文档将详细介绍Clickzetta Lakehouse的约束属性，并通过实例演示如何使用这些属性。
-
-## ANSI SQL约束属性
-
-ANSI SQL约束属性主要涉及以下几个方面：
-
-1. **ENFORCED | NOT ENFORCED**：指定是否强制执行约束。ENFORCED表示强制执行约束，NOT ENFORCED表示不强制执行约束。
-2. **DEFERRABLE | NOT DEFERRABLE**：指定延迟执行和非延迟执行。DEFERRABLE表示可以延迟执行约束，NOT DEFERRABLE表示立即执行约束。
-3. **INITIALLY { DEFERRED | IMMEDIATE** }：指定校验的时机。如果约束属性为NOT DEFERRABLE，则只能是INITIALLY IMMEDIATE。
-
-### 使用示例
-
-假设我们有一个订单表`orders`，其中包含以下字段：
-
-- `order_id`：订单ID，为主键。
-- `customer_id`：客户ID，为外键。
-- `order_date`：订单日期。
-- `total_amount`：订单总金额。
-
-我们可以为`orders`表定义以下约束：
-
-```sql
-CREATE TABLE orders (
-  order_id INT PRIMARY KEY ENFORCED,
-  customer_id INT REFERENCES customers DEFERRABLE INITIALLY DEFERRED,
-  UNIQUE (customer_id, order_date) ENFORCED
-);
-```
-
-在这个例子中，我们为`order_id`指定了ENFORCED属性，以确保每个订单都有一个唯一的ID。对于`customer_id`，我们使用了DEFERRABLE和INITIALLY DEFERRED属性，允许在插入数据时暂时违反外键约束。最后，我们为`customer_id`和`order_date`定义了一个唯一约束，以确保每个客户在同一天只能有一个订单。
-
-## 扩展的约束状态
-
-Clickzetta Lakehouse扩展的约束状态主要用于主键、外键和唯一键。这些约束状态包括：
-
-1. **ENABLE | DISABLE**：指定约束是禁用还是启动。ENABLE表示启动约束，DISABLE表示禁用约束。
-2. **VALIDATE | NOVALIDATE**：指定是否验证表上已有的数据，并创建索引。VALIDATE表示需要验证并创建索引，NOVALIDATE表示不需要验证和创建索引。
-3. **RELY | NORELY**：当指定NOVALIDATE为RELY时，查询优化器会使用此属性，提高查询性能。
-
-### 使用示例
-
-假设我们有一个销售记录表`sales`，其中包含以下字段：
-
-- `sale_id`：销售记录ID，为主键。
-- `product_id`：产品ID，为外键。
-- `sale_date`：销售日期。
-- `amount`：销售金额。
-
-我们可以为`sales`表定义以下约束：
-
-```sql
-CREATE TABLE sales (
-  sale_id INT PRIMARY KEY ENABLE VALIDATE RELY,
-  product_id INT REFERENCES products DISABLE NOVALIDATE NORELY
-);
-```
-
-在这个例子中，我们为`sale_id`指定了ENABLE、VALIDATE和RELY属性，以确保每个销售记录都有一个唯一的ID，并在插入数据时验证外键约束。对于`product_id`，我们使用了DISABLE、NOVALIDATE和NORELY属性，表示在插入数据时不验证外键约束，同时查询优化器可以提高查询性能。
-
-## 云器Lakehouse约束属性
-
-云器Lakehouse约束属性为ENABLE VALIDATE RELY，强制执行约束校验。需要注意的是，这种约束属性只支持使用Java SDK进行写入，不支持使用SQL进行插入。
-
-### 使用示例
-
-假设我们有一个用户表`users`，其中包含以下字段：
-
-- `user_id`：用户ID，为主键。
-- `username`：用户名。
-- `email`：电子邮件地址。
-
-我们可以使用Java SDK为`users`表定义以下约束：
-
-```java
-Table table = session.getTable("users");
-TableSchema schema = table.getSchema();
-PrimaryKeyConstraint primaryKeyConstraint = new PrimaryKeyConstraint("user_id");
-schema.addConstraint(primaryKeyConstraint);
-UniqueConstraint uniqueConstraint = new UniqueConstraint("username");
-schema.addConstraint(uniqueConstraint);
-session.createTable("users", schema, true);
-```
-
-在这个例子中，我们使用Java SDK创建了一个`users`表，并为其定义了一个主键约束和一个唯一约束。这些约束将强制执行，确保每个用户都有一个唯一的ID和用户名。由于使用了云器Lakehouse约束属性，我们无法通过SQL插入数据，只能使用Java SDK进行写入。

-# lakehouse 主键使用说明
-
-## 主键约束概述
-
-**主键（PRIMARY KEY**） 用于确保表中每条记录的唯一性。在大数据场景下，由于数据量通常非常庞大，为了保证数据的唯一性而对所有 key 进行逐一检查是不现实且低效的，因此一般不推荐在大数据环境中使用主键约束。然而，Lakehouse 仍提供了对主键的支持，以便在特定场景下满足数据完整性的需求。在Lakehouse架构中，定义了主键的表在进行实时数据写入时，系统将自动根据主键值进行数据去重，这对于变更数据捕获（CDC）场景尤为重要。例如，您可以实时地将MySQL数据库的binlog日志同步到Lakehouse，确保数据的一致性。设置完主键需要通过[实时数据接口](java_reference/realtime-upload.md)来处理数据。在CDC实时写入过程中，系统将依据主键自动进行数据去重，以维护数据的准确性和完整性。
-
-## lakehouse 主键支持及默认行为
-
-lakehouse 支持两种直接指定 primary key 的方式，且在默认情况下，其行为设置为 `ENABLE VALIDATE RELY`。这意味着，当您在创建表时指定了主键，并且没有特别指定其他行为时，系统会自动启用对主键的验证和依赖关系。
-
-在这种默认行为下，无论是实时写入操作还是通过 SQL 进行的数据写入，系统都会依据所定义的主键进行去重处理。如果尝试插入与现有主键值重复的记录，系统将拒绝执行该插入操作，以确保主键的唯一性。例如：
-
-```sql
-create table test_primary(id int primary key,name string);
-desc extended test_primary;
--- 此时插入成功，因为主键值 1 和 2 均未重复
-insert into test_primary values(1,"1");
-insert into test_primary values(2,"1");
--- 插入失败，因为主键值 1 已存在
-insert into test_primary values(1,"1");
-select * from test_primary;
-```
-
-从上述示例可以看出，在默认的 `ENABLE VALIDATE RELY` 模式下，系统严格维护主键的唯一性，无论是单条记录插入还是批量插入，都会进行主键冲突检查。
-
-## 自定义主键行为
-
-如果您根据实际业务需求，希望在插入数据时仅由实时写入机制进行主键去重，而通过 SQL 写入时则不执行去重操作，可以通过将主键行为设置为 `DISABLE NOVALIDATE RELY` 来实现。以下是具体的操作示例：
-
-```sql
-create table test_primary_di(id int primary key DISABLE NOVALIDATE RELY ,name string);
-insert into test_primary_di values(1,"1");
-insert into test_primary_di values(2,"1");
-
-insert into test_primary_di values(1,"1");
--- 插入成功，因为在 DISABLE NOVALIDATE RELY 模式下，SQL 写入不进行主键去重
-```
-
-需要注意的是，在 `DISABLE NOVALIDATE RELY` 模式下，虽然实时写入仍会依据主键进行去重，但通过 SQL 进行的写入操作将不会受到主键唯一性约束的限制，这可能导致数据中出现主键重复的情况。因此，在选择此种模式时，您需要对数据的写入来源和写入方式进行考虑和管理，以避免潜在的数据质量问题。
-
-# 主键表创建语法
-
-* 不带分区或分桶的主键表
-
-```
-CREATE TABLE pk_table
-(
-    id int,
-    col string,
-PRIMARY KEY (id)
-);
-CREATE TABLE pk_table
-(
-    id int PRIMARY KEY,
-    col string
-);
-```
-
-* 带分桶的主键表。
-  1. **未指定 DISABLE NOVALIDATE RELY 时**：
-
-     * Cluster Key 必须包含主键列
-     * 排序键必须包含主键
-  2. **指定 DISABLE NOVALIDATE RELY 时**：
-
-     * Cluster Key 可不包含主键列
-     * 排序键可不包含主键
-
-```
---指定DISABLE NOVALIDATE RELY
-CREATE TABLE pk_table
-(
-    id int,
-    col string,
-    cluster_key string,
-    PRIMARY key (id) DISABLE NOVALIDATE RELY
-) 
-CLUSTERED BY ( cluster_key)  INTO 16 BUCKETS;
---不指定DISABLE NOVALIDATE RELY
-CREATE TABLE pk_table
-(
-    id int,
-    col string,
-    cluster_key string,
-    PRIMARY key (id)
-) 
-CLUSTERED BY (id, cluster_key) SORTED BY (id) INTO 16 BUCKETS;
-
-
-```
-
-* 带主键的分区表。
-  1. **未指定 DISABLE NOVALIDATE RELY 时**：
-     * Partition Key 必须包含主键列
-  2. **指定 DISABLE NOVALIDATE RELY 时**：
-     * Partition Key 可不包含主键列
-
-```
---指定DISABLE NOVALIDATE RELY
-CREATE TABLE pk_table
-(
-    id int,
-    col string,
-    pt string,
-    PRIMARY key (id)DISABLE NOVALIDATE RELY
-) PARTITIONED BY (pt);
---不指定DISABLE NOVALIDATE RELY
-CREATE TABLE pk_table
-(
-    id int,
-    col string,
-    pt string,
-    PRIMARY key (id, pt)
-) PARTITIONED BY (pt);
-```
-
-# 使用注意事项
-
-**类型选择建议**
-
-* 优先使用数值类型（如 int/bigint 等）
-* 避免使用变长类型（如 string/varchar），以减少索引空间占用
-* 禁止使用浮点数类型（float/double）
-* 禁止使用嵌套类型
-  **约束条件**
-* 主键列必须定义为 NOT NULL
-* 不支持 Schema Evolution（表结构变更后主键不可修改）
-
-# 使用案例
-
-## 创建表
-
-在创建Lakehouse表时，需要指定主键。CDC写入会根据主键进行数据去重，以确保数据的准确性。创建的主键表不支持SQL操作，只能通过实时写入流进行数据写入。创建的主键表不支持也不支持使用SQL添加列和修改列。以下是一个创建表的示例：
-
-```sql
-CREATE TABLE igs_test_upsert (
-    id int PRIMARY KEY,
-    event varchar(100),
-    event_time STRING
-);
-```
-
-## SDK实时写入流
-
-### 创建实时写入流
-
-使用SDK创建实时写入流，需要指定操作类型（CDC）和相关选项。以下是一个创建实时写入流的示例：
-
-```java
-RowStream stream = client.newRealtimeStreamBuilder()
-    .operate(RowStream.RealtimeOperate.CDC)
-    .options(options)
-    .schema(schema)
-    .table(table)
-    .build(); // 关闭流，释放流资源，必须调用
-stream.close();
-```
-
-### 指定操作类型
-
-根据需求，可以指定不同的操作类型：
-
-* `Stream.Operator.UPSERT`：插入或更新行。如果目标行不存在，则插入；如果已存在，则更新。
-* `Stream.Operator.DELETE_IGNORE`：删除行。如果目标行不存在，则自动忽略。
-
-### 使用原生Java Sdk写入
-
-```java
-Row row = stream.createRow(Stream.Operator.UPSERT); // 插入或更新行
-Row rowToDelete = stream.createRow(Stream.Operator.DELETE_IGNORE); // 删除行
-```
-
-## 使用Lakehouse实时同步功能写入
-
-参考文档[多表实时同步](<multitable_realtime_sync.md>)
-
-## 使用FLINK CONNECTOR写入
-
-Flink connector是基于RealtimeStream SDK封装的，用于实现实时数据同步。查看[Flink Connector](<flink-write-connector.md>)

-# 私网连接（Private Link）概述
-
-> 【预览发布】本功能当前处于受邀预览发布阶段。如果需要使用，请联系我们的技术支持人员协助处理。
-
-## 什么是私网连接 Private Link？
-
-**私网连接**（**Private Link**）（如 AWS PrivateLink、阿里云私网连接、腾讯云私有连接等）是云厂商提供的一种安全、私有的网络连接方式，可以让不同 VPC（Virtual Private Cloud）之间通过内网互联，而无需暴露在公网环境下，极大降低数据传输的安全风险。
-
-在 **Lakehouse** 平台中，Private Link 的应用场景主要有两大类：
-
-**1. 用户 VPC → Lakehouse（Inbound）**
-在云厂商的同 region、同可用区内，从用户的 VPC 通过云厂商的 Private Link 服务访问 Lakehouse（JDBC 网关、IGS 等）服务。
-
-:-: ![](.topwrite/assets/未命名绘图.drawio.png)
-
-例如：
-
-某公司在云上构建了自己的业务系统（电商平台、结算系统等），这些系统部署在其私有 VPC 中，不允许对公网开放访问。这家公司将销售交易数据、库存数据统一存储在 Lakehouse。在制作数据可视化、实时分析和报表时，由于内部合规及安全要求，不能通过公网访问 Lakehouse 中的数据。
-
-此时需要使用 Lakehouse 的私网连接功能，建立从客户 VPC 访问 Lakehouse 的终端节点。该公司对 Lakehouse 的访问都在其私有 VPC 中进行，通过终端节点的域名进行访问。
-
-^
-
-**2. Lakehouse → 用户 VPC（Outbound）**
-当需要从 Lakehouse（位于云器 VPC）连接到用户自定义服务（如用户 VPC 内自建的 MySQL 数据库）时，同样通过 Private Link 进行私网访问。
-
-:-: ![](.topwrite/assets/private_link访问客户.png)
-
-例如：
-某金融领域公司选择在 Lakehouse 进行统一数据存储与分析，但其核心业务数据库存放在私有 VPC 内部，且有严格的安全策略，禁止对公网暴露数据库端口。Lakehouse 需要通过实时集成读取数据，用于后续分析、风控模型训练等。
-
-此时首先需要客户在私有 VPC 内建立终端节点服务，然后需要使用 Lakehouse 的私网连接功能建立从 Lakehouse 访问客户 VPC 的终端节点。之后在 Lakehouse 中 [建立数据源](config-datasource.md) 的操作都使用该终端节点的域名和端口进行配置。
-
-^
-
-## 准备工作与注意事项
-
-1. **网络互通与 DNS 配置**
-
-   * 如果需要通过自定义域名（CNAME）访问 Private Link Endpoint，需在企业内部 DNS 中将解析指向 VPC 内的私有 IP。
-
-2. **安全组与端口放行**
-
-   * 当使用 Lakehouse 访问客户 VPC 时，需要客户在其私有 VPC 内，对终端节点服务所关联的负载均衡器（LB）放行相关的内网 IP 和端口。
-
-3. **默认带宽限制**
-
-   * 对于 Lakehouse 提供的终端节点服务，默认带宽为 **5 Mbps**。
-   * 如有大数据量传输需求，请联系 Lakehouse 支持团队提升带宽上限。
-
-4. **终端节点数量与账号管控**
-
-   * 为防止滥用或无序创建，每个云厂商账户 ID 最多只能创建 **5 个**终端节点；超限时 Lakehouse 平台会发出告警。
-
-5. **计费方式**
-
-   * Private Link 流量费用由客户直接支付给云厂商，不经过 Lakehouse 二次计量。
-
-6. **Multi-Account 场景**
-
-   * 如果客户有多个云厂商账户，需要在 Lakehouse 中分别将其账户 ID 添加到白名单；
-   * 并对应创建多个 Private Link Endpoint 进行分别管理。
-
-7. **公网阻断（可选）**
-
-   * 如果希望在完成私网连接后，彻底阻断从公网访问 Lakehouse，可在 Lakehouse 中启用 **网络访问策略**（或云厂商网络策略），仅允许来自指定 VPC 的 IP 范围进行连接。

-## ClickZetta Lakehouse Python SDK 实时写入
-
-## 安装
-
-1. 删除旧版本依赖
-
-如果安装过旧版本的sdk，先卸载旧版本的 clickzetta-connector-python 包 和 clickzetta-sqlalchemy 包
-
-```shell
-pip uninstall clickzetta-connector clickzetta-sqlalchemy clickzetta-ingestion-python clickzetta-ingestion-python-v2 -y
-```
-
-2. 安装 clickzetta-connector，Python版本要求 3.7 以上：
-
-```Bash
-pip install clickzetta-connector
-```
-
-## **实时写入原理**
-
-实时写入 Lakehouse 的Python SDK是一种高效的数据流处理工具，它允许用户将数据实时地上传并存储到Lakehouse中。以下是实时写入的工作原理：
-
-1. SDK上传数据 ：用户通过Python SDK将数据实时上传到Lakehouse的Ingestion Service。
-2. Ingestion Service处理 ：Ingestion Service接收到数据后，直接将数据写入到Lakehouse的表中，此时数据以临时中间文件的形式存储，这个阶段称为 混合表 。
-3. 查询实时数据 ：在数据提交之前，用户即可查询（select）到这些实时写入的新数据，但这些数据对于table stream、materialized view和dynamic table来说是不可见的。
-4. 数据提交 ：新写入的数据会在大约一分钟后自动提交，提交后，table stream、materialized view和dynamic table都能够读取这部分数据。
-5. 混合表变成普通表 ：在数据提交后，后台进程会将混合表合并变成普通表，合并完成后用户可以执行更新操作（update\merge\delete）。
-
-## **适用场景**
-
-实时写入 Lakehouse 的 Python SDK 适用于以下场景：
-
-* 短间隔数据导入 ：如果您的应用场景要求在非常短的时间间隔内（如5分钟或更短）导入数据，实时写入SDK可以满足您的需求。
-* 频繁小量数据提交 ：对于需要频繁提交数据，但每次提交的数据量不大的情况，实时写入SDK提供了一个高效的解决方案。
-* 实时数据分析 ：实时写入SDK适合需要对数据进行即时分析和响应的应用，例如实时监控、事件追踪和实时报告等。
-
-## **注意事项**
-
-* 实时写入的数据可以秒级查询。
-* 实时写入数据目前只能通过内部提供的 Flink Connector 中支持 schema change 的 sink 算子（单并发）来实现实时的表结构变化感知。在其他场景下进行表结构更改时，需要先停止实时写入任务，然后在表结构变更后一段时间（大约90分钟）后，重新启动任务。
-* table stream、materialized view 和 dynamic table 只能显示已经提交的数据。实时任务写入的数据需要等待 1 分钟才能确认，因此 table stream 也需要等待 1 分钟才能看到。
-
-## **数据类型支持**
-
-Lakehouse Python SDK支持以下数据类型映射：
-
-| SQL数据类型               | Python内部数据结构                   |
-| --------------------- | ------------------------------ |
-| BOOLEAN               | bool                           |
-| STRING / JSON         | str                            |
-| CHAR(n) / VARCHAR(n)  | str(超限写入将截断)                   |
-| BINARY                | bytes                          |
-| DECIMAL               | Decimal                        |
-| INT8                  | int                            |
-| INT16                 | int                            |
-| INT32                 | int                            |
-| INT64                 | int                            |
-| FLOAT                 | float                          |
-| DOUBLE                | float                          |
-| DATE                  | date                           |
-| TIMESTAMP\_LTZ        | datetime(tz=timezone)          |
-| TIMESTAMP\_NTZ        | datetime                       |
-| INTERVAL\_DAY\_TIME   | interval\_day\_time            |
-| INTERVAL\_YEAR\_MONTH | -                              |
-| ARRAY                 | list                           |
-| MAP                   | map                            |
-| STRUCT                | json or collections.namedtuple |
-
-## **通过客户端创建实时数据流**
-
-要创建实时数据流，首先需要使用 Lakehouse 客户端连接：
-
-```Python
-from clickzetta.connector.v0.connection import connect
-from clickzetta.connector.v0.enums import RealtimeOperation
-from clickzetta_ingestion.realtime.realtime_options import RealtimeOptionsBuilder, FlushMode
-from clickzetta_ingestion.realtime.arrow_stream import RowOperator
-
-
-# 创建连接
-with connect(username='your_username',
-             password='your_password',
-             service='your_service_endpoint',
-             instance='your_instance',
-             workspace='your_workspace',
-             schema='your_schema',
-             vcluster='your_vcluster') as conn:
-    
-    # 创建实时数据流
-    stream = conn.get_realtime_stream(
-        schema="your_schema",
-        table="your_table",
-        operate=RealtimeOperation.APPEND_ONLY,  # 普通表使用APPEND_ONLY
-        options=RealtimeOptionsBuilder().with_flush_mode(FlushMode.AUTO_FLUSH_BACKGROUND).build()
-    )
-    
-    # 使用完毕后关闭流
-    stream.close()
-```
-
-参数说明：
-
-* operate : 传入一个枚举值，实时接口支持 RealtimeOperation.APPEND\_ONLY 和 RealtimeOperation.CDC
-
-  * 普通表使用 RealtimeOperation.APPEND\_ONLY
-  * 主键表必须使用 RealtimeOperation.CDC
-
-* options : 用于传入实时写入流的参数，详见下文的选项说明
-
-## **选项（Options**）
-
-在Python SDK中，可以通过`RealtimeOptionsBuilder`类来配置实时写入流的参数。这些参数均为选填，推荐使用默认参数。
-
-```Python
-from clickzetta.ingestion.realtime.realtime_options import RealtimeOptionsBuilder, FlushMode, RetryStatus
-
-options = RealtimeOptionsBuilder()\
-        .with_flush_mode(FlushMode.AUTO_FLUSH_BACKGROUND) \
-        .with_mutation_buffer_lines_num(50000) \
-        .with_mutation_buffer_max_num(50) \
-        .with_mutation_buffer_space(20 * 1024 * 1024) \
-        .with_flush_interval(10 * 1000) \
-        .with_request_failed_retry_enable(True) \
-        .with_request_failed_retry_times(5) \
-        .with_request_failed_retry_internal_ms(5 * 1000) \
-        .with_request_failed_retry_log_debug_enable(True) \
-        .with_request_failed_retry_status([
-        RetryStatus.THROTTLED,
-        RetryStatus.INTERNAL_ERROR,
-        RetryStatus.FAILED,
-        RetryStatus.PRECHECK_FAILED]) \
-        .build()
-```

-
-## 写入数据（Row）
-
-通过`stream.create_row`方法创建具体的数据对象（Row），并通过`row.set_value`方法将数据封装到Row对象中。
-
-```Python
-# 创建一行数据
-row = stream.create_row(RowOperator.INSERT)  # 普通表使用INSERT
-
-# 设置字段值
-row.set_value("id", 1)
-row.set_value("name", "test_name")
-
-# 应用行数据到流中
-stream.apply(row)
-```
-
-**Row类型说明**：
-
-* 当Stream创建为`RealtimeOperation.APPEND_ONLY`时，仅能创建`RowOperator.INSERT`类型的Row。
-* 当Stream创建为`RealtimeOperation.CDC`时，可以使用以下Row类型：
-  * `RowOperator.UPSERT`：插入行，如果目标行已存在则更新该行。
-  * `RowOperator.DELETE_IGNORE`：删除行，如果目标行不存在则自动忽略。
-
-**注意**：主键表(PK表)必须使用CDC模式，且只能使用UPSERT和DELETE\_IGNORE操作类型。
-
-## 数据提交到服务端
-
-通过调用`stream.flush()`方法，数据会立即提交到服务端。如果没有显式调用此方法，数据会根据以下条件之一被自动提交：
-
-1. 达到`with_mutation_buffer_space`设置的缓冲区大小
-2. 达到`with_mutation_buffer_lines_num`设置的行数
-3. 达到`with_flush_interval`设置的时间间隔
-
-## 具体案例
-
-### 主键表（PK表）写入完整示例
-
-```Python
-from clickzetta.connector.v0.connection import connect
-from clickzetta.connector.v0.enums import RealtimeOperation
-from clickzetta_ingestion.realtime.arrow_stream import RowOperator
-from clickzetta_ingestion.realtime.realtime_options import RealtimeOptionsBuilder, FlushMode
-
-with connect(username='your_username',
-             password='your_password',
-             service='your_service_endpoint',
-             instance='your_instance',
-             workspace='your_workspace',
-             schema='your_schema',
-             vcluster='default') as conn:
-    
-    # 创建主键表
-    cursor = conn.cursor()
-    cursor.execute("""
-    CREATE TABLE test_pk (
-        id STRING NOT NULL PRIMARY KEY,
-        name STRING,
-        age INT
-    )
-    """)
-    
-    # 创建实时数据流 - 主键表必须使用CDC
-    stream = conn.get_realtime_stream(
-        schema=conn.get_schema(),
-        table="test_pk",
-        operate=RealtimeOperation.CDC,
-        options=RealtimeOptionsBuilder().with_flush_mode(FlushMode.AUTO_FLUSH_SYNC).build()
-    )
-    
-    # 写入数据 - 主键表使用UPSERT
-    for i in range(10):
-        row = stream.create_row(RowOperator.UPSERT)
-        row.set_value('id', f"id_{i}")
-        row.set_value('name', f"user_{i}")
-        row.set_value('age', 20 + i)
-        stream.apply(row)
-    
-    # 更新数据 - 主键表使用UPSERT
-    for i in range(5):
-        row = stream.create_row(RowOperator.UPSERT)
-        row.set_value('id', f"id_{i}")
-        row.set_value('name', f"updated_user_{i}")
-        row.set_value('age', 30 + i)
-        stream.apply(row)
-    
-    # 删除数据 - 主键表使用DELETE_IGNORE
-    for i in range(2):
-        row = stream.create_row(RowOperator.DELETE_IGNORE)
-        row.set_value('id', f"id_{i}")
-        stream.apply(row)
-    
-    # 关闭流
-    stream.close()
-    
-    # 验证结果
-    cursor.execute("SELECT COUNT(*) FROM test_pk")
-    count = cursor.fetchone()[0]
-    print(f"剩余记录数: {count}")  # 应该是8条记录(10-2)
-```
-
-## 常见问题与解决方案
-
-### 1. 主键表写入失败
-
-**问题**: 向主键表写入数据时出现错误。
-
-**解决方案**:
-
-* 确保使用了正确的操作类型：主键表必须使用`RealtimeOperation.CDC`模式，且只能使用`RowOperator.UPSERT`和`RowOperator.DELETE_IGNORE`操作。
-* 确保主键字段已正确设置值。
-* 主键表不支持`FlushMode.AUTO_FLUSH_BACKGROUND`，会自动重置为`FlushMode.AUTO_FLUSH_SYNC`。
-* 分区列要求是primary key的子集。
-
-### **2. 内存占用过高**
-
-**问题**: 写入大量数据时内存占用过高。
-
-**解决方案**:
-
-* 减小`with_mutation_buffer_lines_num`和`with_mutation_buffer_space`参数值。
-* 定期调用`stream.flush()`手动刷新数据，并尽量避免 flush 过于频繁，会导致大量小文件产生。
-* 考虑分批写入数据而不是一次性写入大量数据。
-
-## 总结
-
-ClickZetta Python SDK的实时写入功能提供了高效、灵活的数据写入方式，支持各种数据类型和操作模式。通过合理配置参数，可以根据不同场景优化写入性能。
-
-对于主键表和普通表，需要使用不同的操作模式和行操作类型。主键表必须使用CDC模式，且只能使用UPSERT和DELETE\_IGNORE操作；普通表通常使用APPEND\_ONLY模式和INSERT操作。

-# Python任务安装分发包与导入使用指南
-
-本文用于指导在 Python 任务中，从官方源或清华源安装分发包，并在后续代码中稳定导入使用。
-
-## 适用场景
-
-* 需要在任务运行时临时安装第三方包。
-* 需要从公网官方源（PyPI）或国内镜像（清华源等）安装包。
-* 需要将包安装到自定义目录（如 `/home/system_normal`）后再 `import`。
-
-## 运行时安装说明
-
-* Python 任务运行在临时 Pod 中，任务结束后环境会销毁。所以每次运行都需要重新安装该依赖，不要依赖“上一次安装结果”。
-* 必须使用 `--target` 安装，且必须把该目录加入 `sys.path` 后再导入。因为当前python运行时环境无 Root 权限，无法安装到全局 site-packages 目录，只能安装到用户目录下（如 `/home/system_normal`）。
-* 清华源（网络受限时可选）：`https://pypi.tuna.tsinghua.edu.cn/simple`
-
-## 标准模板（推荐直接复用）
-
-```python
-import subprocess
-import sys
-
-TARGET_DIR = "/home/system_normal"
-subprocess.check_call([
-    sys.executable, "-m", "pip", "install",
-    "config",
-    "--target", TARGET_DIR,
-    "-i", "https://pypi.tuna.tsinghua.edu.cn/simple"
-])
-sys.path.append(TARGET_DIR)
-
-from config import *
-```
-
-
-## 快速切换到清华源
-
-仅需把模板中的 `INDEX_URL` 改为：
-
-```python
-INDEX_URL = "https://pypi.tuna.tsinghua.edu.cn/simple"
-```
-
-## 常见错误与排查
-
-### 报错：`ModuleNotFoundError: No module named 'xxx'`

-### 简单查询案例
-
-```python
-#创建游标对象
-cursor = conn.cursor()
-#执行 SQL 查询
-cursor.execute('SELECT * FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live LIMIT 10;')
-#获取查询结果
-results = cursor.fetchall()
-for row in results:
-print(row)
-```
-
-### 使用 SQL hints
-
-在 JDBC 中通过 set 命令设置的 SQL hints 可以通过 `parameters` 参数传递，支持的参数请参考 [参数管理](../sql-parmaters.md)。以下是一个示例：
-
-```python
-#设置作业运行超时时间为 30 秒
-my_param = {
-    'hints': {
-        'sdk.job.timeout': 30
-    }
-}
-cursor.execute('YOUR_SQL_QUERY', parameters=my_param)
-```
-
-### 使用
-
-## 更多示例
-
-### 1. 处理查询结果
-
-以下示例展示了如何处理查询结果，例如将结果保存到 CSV 文件中：
-
-```python
-import csv
-
-# 执行查询
-cursor.execute('SELECT * FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live LIMIT 10;')
-
-# 获取查询结果
-results = cursor.fetchall()
-
-# 将结果保存到 CSV 文件
-with open('output.csv', 'w', newline='', encoding='utf-8') as csvfile:
-    csv_writer = csv.writer(csvfile)
-    csv_writer.writerow([column[0] for column in cursor.description])
-    csv_writer.writerows(results)
-# 关闭连接
-cursor.close()
-conn.close()
-```
-
-### 高级功能
-
-> 注意：以下高级功能需要使用 `clickzetta-connector-python >= 0.8.82` 版本，或者 clickzetta-connector 版本 >= 1.0.11。
-
-#### 参数绑定
-
-clickzetta-connector 支持两种参数绑定风格，遵循 [PEP-249](https://peps.python.org/pep-0249/#paramstyle) 规范：
-
-| paramstyle | 描述                             | 示例                                    |
-| ---------- | ------------------------------ | ------------------------------------- |
-| qmark      | 使用问号 (?) 作为参数占位符                | `INSERT INTO test VALUES (?)`         |
-| pyformat   | 使用 Python 扩展格式代码，例如 `%(name)s` | `INSERT INTO test VALUES (%(value)s)` |
-
-##### 使用问号风格 (qmark)
-
-```python
-# 简单示例
-cursor.execute('INSERT INTO test (id, name) VALUES (?, ?)', binding_params=[1, 'test'])
-
-# JSON 类型示例
-json_data = "JSON '" + '{"id": 2, "value": "100", "comment": "JSON Sample data"}' + "'"
-my_param = {
-    'hints': {
-        'sdk.job.timeout': 30
-    }
-}
-cursor.execute('INSERT INTO test (id, json_col) VALUES (?, ?)', my_param, binding_params=[1, json_data])
-```
-
-##### 使用 qmark 风格批量插入
-
-使用 `executemany()` 方法支持高效地使用 qmark 风格执行批量插入操作：
-
-```python
-# 准备数据
-data = [
-    (1, 'test1'),
-    (2, 'test2'),
-    (3, 'test3')
-]
-
-# 执行批量插入
-cursor.executemany('INSERT INTO test (id, name) VALUES (?, ?)', data)
-```
-
-如需对输入的数据根据表结构进行自动转换，请开启 `tolerant` 参数并指定类型：
-
-```python
-# 准备数据
-data = [
-    (1, 'test1'),
-    (2, 0),
-    (3, 0.1)
-]
-
-hints = {'hints': {
-    "cz.sql.type.conversion": "tolerant"
-}}
-
-# 执行批量插入
-cursor.executemany('INSERT INTO test (id, name) VALUES (int(?), string(?))', data, hints)
-```
-
-##### 使用 Python 格式风格 (pyformat)
-
-```python
-# 使用命名参数
-data = {'id': 1, 'name': 'test'}
-cursor.execute('INSERT INTO test (id, name) VALUES (%(id)s, "%(name)s")', data)
-```
-
-> 注意：在 pyformat 风格中，参数值为字符串时插入需要加引号。
-
-##### 完整示例：复杂数据类型的批量插入
-
-以下示例展示了如何使用 `executemany` 插入包含各种数据类型的数据：
-
-```python
-table = 'test_table'
-cursor.execute(f'''
-    CREATE TABLE {table} (
-        c_bigint BIGINT,
-        c_boolean BOOLEAN,
-        c_binary BINARY,
-        c_char CHAR,
-        c_date DATE,
-        c_decimal DECIMAL(20, 6),
-        c_double DOUBLE,
-        c_float FLOAT,
-        c_int INT,
-        c_interval INTERVAL DAY,
-        c_smallint SMALLINT,
-        c_string STRING,
-        c_timestamp TIMESTAMP,
-        c_tinyint TINYINT,
-        c_array ARRAY<STRUCT<a: INT, b: STRING>>,
-        c_map MAP<STRING, STRING>,
-        c_struct STRUCT<a: INT, b: STRING, c: DOUBLE>,
-        c_varchar VARCHAR(1024),
-        c_json JSON
-    )
-''')
-
-data = [
-    (
-        1,
-        True,
-        b'\x01',
-        'a',
-        datetime.date(2022, 2, 1),
-        1000.123456,
-        2.0,
-        1.5,
-        42,
-        'INTERVAL 1 DAY',
-        103,
-        'test string 1',
-        datetime.datetime.now(),
-        11,
-        [(1, 'A')],
-        {'key1': 'value1'},
-        (1, 'A', 2.0),
-        'varchar example 1',
-        ("JSON '" + '{"id": 2, "value": "100", "comment": "JSON Sample data"}' + "'")
-    )
-]
-sql = f'''
-    INSERT INTO {table} (
-        c_bigint, c_boolean, c_binary, c_char, c_date, c_decimal, c_double, 
-        c_float, c_int, c_interval, c_smallint, c_string, c_timestamp, 
-        c_tinyint, c_array, c_map, c_struct, c_varchar, c_json
-    ) VALUES (
-        ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?
-    )
-'''
-
-cursor.executemany(sql, data)
-my_param = {'hints': {}}
-
-# 获取结果
-cursor.execute(f'SELECT * FROM {table}', my_param)
-result = cursor.fetchall()
-```
-
-#### 异步执行 (execute\_async)
-
-`execute_async()` 方法支持异步执行 SQL 查询，特别适用于长时间运行的查询：
-
-```python
-# 异步执行查询
-cursor.execute_async('SELECT * FROM large_table')
-
-# 检查查询是否完成
-while not cursor.is_job_finished():
-    print("查询执行中...")
-    time.sleep(1)
-
-# 获取结果
-results = cursor.fetchall()
-```
-
-#### 注意事项
-
-* 不支持 commit 和 rollback 接口

-# Python/Shell 任务中使用数据源
-
-## 功能概述
-
-Python/Shell 任务，支持使用预先配置好的[数据源](config-datasource.md)。通过在运行环境里内置的 `clickzetta-dbutils` 工具包，在任务中可直复用`管理->数据源`中的连接配置信息，无需在节点中通过代码来重复设定，可提高敏感信息的安全性，也带来了开发和管理的便捷。
-
-^
-
-当前支持的数据源包括：
-
-* Lakehouse数据源
-* MySQL数据源
-* PostgreSQL数据源
-
-##
-
-## 界面操作指南
-
-### 在Python/Shell任务中选择数据源
-
-在Python/Shell任务的配置面板中，可以选择使用一个或多个数据源（确保数据源已经在管理->数据源里新建并测试连通通过）。该配置会作用于当前任务的直接运行或调度运行：
-
-![](.topwrite/assets/image_1742284598370.png =560)
-
-*注：当前工作空间的默认 Lakehouse 数据源，在此处不需添加即可在代码里直接访问*。
-
-###
-
-### 在代码中访问数据源
-
-添加完数据源后，即可开始编写 Python/Shell 任务代码，我们需要调用 `clickzetta_dbutils` python库中提供的 `get_active_engine("your_datasource_name")` 函数，仅需填写数据源名称，无需指定数据源URL、密码等连接信息即可完成数据源的连接。另外，还支持使用 `Builder` 模式，详见下文的 API 使用指南和代码示例。

-
-```Python
-def use_options(self, options: dict) -> 'DatabaseConnectionManager'
-```
-
-*注*：*由于我们使用SQLAlchemy的设计，Postgres schema 应该填写为* `undefined"})`
-
-#### use\_query
-
-设置连接的查询参数。
-
-```Python
-def use_query(self, query: dict) -> 'DatabaseConnectionManager'
-```
-
-#### build
-
-根据数据源名称和可选配置创建SQLAlchemy引擎。
-
-```Python
-def build(self, *args, **kwargs) -> Engine
-```
-
-#### 使用示例
-
-```py
-from clickzetta_dbutils import DatabaseConnectionManager
-
-# 链式调用示例
-engine = DatabaseConnectionManager("mysql_source_name")\
-    .use_schema("test_schema")\
-    .use_options({"charset": "utf8"})\
-    .build()
-
-# Lakehouse连接示例
-engine = DatabaseConnectionManager("LAKEHOUSE_source_name")\
-    .use_vcluster("default")\
-    .use_workspace("test-workspace")\
-    .use_schema("public")\
-    .build()
-```
-
-> 备注：其中 “LAKEHOUSE\_source\_name” 是指数据源管理中Lakehouse数据源的名称。
-
-## 代码示例
-
-### Python节点中使用PostgreSQL数据源示例
-
-示例为获取 postgres\_source\_name 数据源的所有 pg tables:
-
-```py
-from sqlalchemy import text
-from clickzetta_dbutils import get_active_engine
-
-# 使用默认schema
-engine = get_active_engine("postgres_source_name")
-with engine.connect() as conn:
-    results = conn.execute(text("SELECT * FROM pg_tables WHERE schemaname = 'public';"))
-    for row in results:
-        print(row)
-
-# 指定database和options中指定schema
-engine = get_active_engine("postgres_source_name", 
-                          schema="pg_database", 
-                          options={"search_path":"pg_schema"})
-```
-
-###
-
-### Python节点中使用MySQL数据源示例
-
-```py
-from sqlalchemy import text
-from clickzetta_dbutils import DatabaseConnectionManager
-
-# 查看所有可用的数据源配置
-print(DatabaseConnectionManager.load_connection_configs())
-
-# 创建连接并指定schema
-manager = DatabaseConnectionManager("mysql_source_name")
-manager.use_schema("test_schema")
-engine = manager.build()
-
-with engine.connect() as conn:
-    result = conn.execute(text("select * from test_table limit 1;"))
-```
-
-###
-
-### Python节点中使用Lakehouse数据源示例
-
-```py
-from sqlalchemy import text
-from clickzetta_dbutils import get_active_engine
-
-# 方式一：使用get_active_engine
-engine = get_active_engine("LAKEHOUSE_source_name", 
-                          vcluster="default", 
-                          workspace="test-workspace", 
-                          schema="public")
-
-# 方式二：使用get_active_lakehouse_engine
-from clickzetta_dbutils import get_active_lakehouse_engine
-engine = get_active_lakehouse_engine(vcluster="default", 
-                                   workspace="test-workspace")
-with engine.connect() as conn:
-    results = conn.execute(text("select 1"))
-    for row in results:
-        print(row)
-```
-
-###
-
-### Shell节点中使用数据源示例
-
-在Shell节点中，可以通过创建Python脚本文件的方式使用数据源：
-
-```bash
-cat >> /tmp/db_utils_demo.py << EOF
-from sqlalchemy import text
-from clickzetta_dbutils import get_active_engine
-
-engine = get_active_engine("postgres_source_name")
-with engine.connect() as conn:
-    results = conn.execute(text("SELECT * FROM test_table;"))
-    for row in results:
-        print(row)
-EOF
-
-python /tmp/db_utils_demo.py
-```
-
-##
-
-## 注意事项
-
-1. 数据源配置支持在Adhoc执行和调度执行两种场景下使用。
-2. 使用不存在的数据源名称会报错，请确保在使用前，Studio 中 `开发 -> python 任务 -> 数据源` 要选择相应的数据源。Postgres和MySQL数据源必须要在 `管理->数据源 `中新建并测试连通并确保通过。
-3. 使用Lakehouse数据源时必须配置vcluster参数。Lakehouse数据源直接使用在 `管理->数据源 `看到的内置Lakehouse数据源。
-4. 数据源的连接信息会被安全处理，可避免明文密码泄露。
-5. 支持在同一个节点中使用多个不同类型的数据源。

-# Lakehouse SQL查询语句
-
-## 功能简介
-
-Lakehouse支持使用标准的SQL SELECT语句进行数据查询。本文档将详细介绍查询语句的基本语法、参数说明以及使用示例，帮助您更高效地进行数据查询。
-
-## 基本语法
-
-```SQL
-[WITH cte [, ...] ]
-SELECT 
-[ hints ] 
-[ ALL | DISTINCT ]
-select_expr [, (except_expr)] ...
-FROM table_reference
-[WHERE where_condition ] 
-[GROUP BY [GROUPING SETS | ROLLUP | CUBE] {col_name | expr | position}]
-    [ HAVING having_condition ]
-[ ORDER BY order_condition [ ASC | DESC ] ]
-[ LIMIT  <number> [OFFSET <number>]]
-```
-
-## 参数说明
-
-**1. WITH cte** (可选)
-[公用表表达式](WITH.md)，用于在查询中定义临时结果集。
-
-**2. ALL | DISTINCT** (可选)：对结果集进行刷选，all 为全部，distinct 将刷选出重复列，默认为 all
-
-```
---表示不对cp_start_date_sk去重
-SELECT ALL cp_start_date_sk FROM catalog_page;
---表示对cp_start_date_sk去重
-SELECT DISTINCT cp_start_date_sk FROM catalog_page;
-```
-
-**3. HINTS** (可选): 帮助Lakehouse优化器作出更好的计划决策。目前支持[map join](mapjoin.md)如下案例
-
-```SQL
-SELECT /*+ MAPJOIN (t2) */ * FROM table1 t1
-JOIN table2 t2
-ON (t1.emp_id = t2.emp_id);
-```
-
-**4. select\_expr** (必填)
-指定需要查询的列，支持列名、列表达式等。例如：col1\_name, col2\_name, 列表达式, ...
-
-**1）排除列**（可选）
-可选。`except_expr`格式为`except(col1_name, col2_name, ...)`。当您希望读取表内大多数列的数据，同时要排除表中少数列的数据时，可以通过`SELECT * except(col1_name, col2_name, ...) from ...;`语句实现，表示读取表数据时会排除指定列（col1、col2）的数据。
-
-命令示例如下。
-
-```SQL
---表结构如下
-DESC students;
-+-------------+-----------+---------+
-| column_name | data_type | comment |
-+-------------+-----------+---------+
-| name        | string    |         |
-| class       | string    |         |
-+-------------+-----------+---------+
---排除class列
-SELECT * EXCEPT(class) FROM students LIMIT 1;
-+-------+
-| name  |
-+-------+
-| Alice |
-+-------+
-```
-
-**2）where\_condition** (可选)
-过滤条件，用于筛选满足指定条件的数据。支持关系运算符、like、rlike、in、not in、between…and等。
-
-* 配合关系运算符，筛选满足指定条件的数据。关系运算符包含：
-
-  * `>`、`<`、`=`、`>=`、`<=`、`<>`
-  * `like`、`rlike`
-  * `in`、`not in`
-  * `between…and`
-
-**5. GROUP BY expression**(可选)
-
-通常，group by和聚合函数配合使用，根据指定的普通列、分区列或正则表达式进行分组。`Grouping Sets`、`Rollup`、`Cube` 为 group by 的扩展，详细可以参考[GROUPING SET](groupby.md)，group by使用规则如下：
-
-* group by操作优先级高于select操作，因此group by的取值是select输入表的列名或由输入表的列构成的表达式。需要注意的是：
-
-  * group by取值为正则表达式时，必须使用列的完整表达式。
-  * select语句中没有使用聚合函数的列必须出现在group by中。
-
-**6. having\_condition**(可选)
-通常`having`子句与聚合函数一起使用，实现过滤。
-
-**7. order\_condition** (可选)
-对所有数据按照指定列或常量进行全局排序。默认为升序排序，可使用`desc`关键字进行降序排序。默认情况下，升序排序会将 `NULL` 值放在最前面，而降序排序则将 `NULL` 放在最后面。Order by 是比较耗时耗资源的操作，因为所有数据都需要发送到 1 个节点后才能排序，排序操作相比不排序操作需要更多的内存。
-
-**8. LIMIT ... OFFSET** (可选)
-
-* LIMIT \<number> 表示查询结果只返回前 \<number> 条记录，其中 \<number> 是一个正整数。这个语法可以用来分页或者限制查询的数据量。支持LIMIT m,n写法。**使用 limit  offset的时候要加上 order by 才有意义，否则每次执行的数据可能会不一致**
-* OFFSET \<number> 表示查询结果跳过前 \<number> 条记录，然后返回剩余的记录，其中 \<number> 是一个正整数。这个语法可以用来指定查询的起始位置。OFFSET关键字也可以用逗号代替
-* LIMIT 和 OFFSET 可以同时使用，也可以单独使用。如果同时使用，那么 OFFSET 必须在 LIMIT 之后。例如，LIMIT 10 OFFSET 20 表示查询结果跳过前 20 条记录，然后返回接下来的 10 条记录。
-
-## 查询历史版本数据
-
-除标准 `SELECT` 选项外，Lakehoue还支持用户在定义的时间段内的任何时间点访问历史数据，包括已更改或删除的数据。支持查询表、动态表和物化视图
-**请注意**：对象的历史查询取决于数据的保留周期。当前版本的数据保留周期默认为1天。您可以通过执行[ALTER命令](TIMETRAVEL.md)来调整保留周期。请注意，修改保留周期可能会增加存储成本。具体使用方式参考[TIME TRAVEL](TIMETRAVEL.md)
-
-```sql
-SELECT 
-    table_identifier TIMESTAMP AS OF timestamp_expression
-```
-
-通过使用TIMESTAMP AS OF子句，用户可以指定具体的时间点，查询保留期内表历史记录中指定点的精确位置或紧邻指定点之前的数据。Timestamp\_expression是一个返回时间戳类型表达式的参数，例如：
-
-* `'2023-11-07 14:49:18'`，即可强制转换为时间戳的字符串。
-* `CAST('2023-11-07 14:49:18' AS TIMESTAMP)`。
-* `CURRENT_TIMESTAMP() - INTERVAL 12 HOURS`。12小时之前的版本
-* 任何本身是时间戳类型或可强制转换为时间戳的表达式。
-  使用示例
-
-```
-SELECT * FROM events TIMESTAMP AS OF TIMESTAMP'2024-10-18 22:15:12.013'
-```
-
-## 语法糖：Trailing Commas
-
-在SQL语句中，使用Trailing Commas可以让语句更容易阅读和编辑。即使在最后一个值或参数后面多了一个逗号，也不会报错。例如：
-
-```SQL
-SELECT    client_ip,
-          client_identity,
-          userid,
-          user_agent,
-          log_time
-          -- status_code 
-FROM      server_logs;
-```
-
-## 注意事项
-
-* 建议您将提交的查询文本（即SQL语句）的大小限制为每个语句5MB。大于5MB的SQL文本将无法提交。如果您有超出5MB的SQL文本，请提交工单解决。
-  当然可以，以下是根据您提供的 Apache Doris `SELECT` 语句文档和 Lakehouse SQL查询语句文档，生成的使用示例和最佳实践：
-
-### 使用示例
-
-1. **基本查询**
-   ```SQL
-   -- 查询所有学生的姓名和班级
-   SELECT name, class FROM students;
-   ```
-
-2. **使用WITH子句（公用表表达式**）
-   ```SQL
-   WITH ranked_students AS (
-     SELECT name, class, RANK() OVER (ORDER BY score DESC) as rank
-     FROM students
-   )
-   SELECT * FROM ranked_students WHERE rank <= 10;
-   ```
-
-3. **去重查询**
-   ```SQL
-   -- 查询不同的班级名称
-   SELECT DISTINCT class FROM students;
-   ```
-
-4. **使用HINTS优化查询**
-   ```SQL
-   SELECT /*+ MAPJOIN(t2) */ * FROM students t1
-   JOIN classes t2 ON t1.class_id = t2.id;
-   ```
-
-5. **条件筛选**
-   ```SQL
-   -- 查询年龄大于20岁的学生姓名
-   SELECT name FROM students WHERE age > 20;
-   ```
-
-6. **GROUP BY 和聚合函数**
-   ```SQL
-   -- 按班级分组，查询每个班级的平均成绩
-   SELECT class, AVG(score) FROM students GROUP BY class;
-   ```
-
-7. **使用HAVING子句**
-   ```SQL
-   -- 查询平均成绩大于60分的班级
-   SELECT class, AVG(score) as avg_score FROM students GROUP BY class HAVING avg_score > 60;
-   ```
-
-8. **ORDER BY 和 LIMIT**
-   ```SQL
-   -- 查询成绩降序排列的前5名学生
-   SELECT name, score FROM students ORDER BY score DESC LIMIT 5;
-   ```
-
-9. **查询历史版本数据**
-   ```SQL
-   -- 查询2024-10-18 22:15:12.013时刻的学生表数据
-   SELECT * FROM students TIMESTAMP AS OF TIMESTAMP'2024-10-18 22:15:12.013';
-   ```
-
-10. join示例
-    参考[Join](JOIN.md)相关使用
-
-## 最佳实践
-
-1. **利用分区分桶过滤**
-   * 尽可能利用Lakehouse的分区分桶作为数据过滤条件，减少数据扫描范围。
-
-2. **使用索引字段**
-   * 充分利用Lakehouse的索引字段作为数据过滤条件加速查询速度。参考[索引](guid-index.md)。
-
-3. **合理使用聚合**
-   * 聚合操作应该在数据量较大时使用，以减少数据传输和提高查询效率。
-
-4. **使用ORDER BY和LIMIT进行分页**
-   * 当需要分页查询时，使用ORDER BY和LIMIT组合可以有效地获取特定页面的数据。
-
-5. **注意数据类型匹配**
-   * 在使用UNION或JOIN时，确保连接的列具有相同的数据类型。
-
-6. **避免大查询文本**
-   * 将查询文本大小限制在5MB以内，以避免提交失败。
-
-7. **使用HAVING子句过滤聚合结果**
-   * HAVING子句应该在聚合函数之后使用，以过滤聚合后的结果集。
-
-8. **使用WITH子句简化复杂查询**
-   * 公用表表达式（WITH子句）可以简化复杂的查询，使其更易于理解和维护。
-
-9. **注意查询成本**
-   * 修改数据保留周期可能会增加存储成本，合理设置数据保留周期以平衡查询需求和成本。

-# 入门指南：如何快速创建同步任务来导入数据
-
-## 适用场景
-
-如果您的数据存储在数据库、对象存储等系统上，需要导入到 Lakehouse 进行处理和分析，则适合阅读本文档。如果您需要导入存在本地文件中的数据，可以直接参考 [如何快速上传导入本地数据](quick_start_upload_data.md)，会更加便捷。
-
-## 前置阅读
-
-在阅读本指南之前，建议先阅读并理解以下文档：
-
-* [Lakehouse 产品简介](what_is_clickzetta_lakehouse.md)
-* [产品基本概念](Key_Concepts.md)
-* [Lakehouse Studio 快速导览](LakehouseStudioTour.md)
-* [数据同步功能概述](data-integration-intro.md)
-* [数据源管理与配置指南](config-datasource.md)
-
-## 操作指南
-
-您可以通过 Lakehouse Studio 提供的「同步任务」功能，将数据库、对象存储等系统上的数据同步导入到 Lakehouse 中。本文以MySQL作为源端为例进行介绍。
-
-### 使用说明
-
-* 同步任务采用从源端拉取数据的方式，依赖源端数据源网络可达性。建议使用具备公网访问能力的数据源进行功能体验。在复杂网络情况下，例如需要同步 VPC 内的数据库数据，需要进行网络打通，可参考 [利用 PrivateLink 通过 VPC 网络同步 RDS 数据(阿里云)](StudioDI_PrivateLinkVPC_fromRDS.md) 文档详细了解。
-* 需要具备 `工作空间管理员角色（workspace_admin）` 或 `工作空间开发角色(workspace_dev)` 权限的用户，才能使用「同步任务」功能。
-
-### 操作步骤
-
-1. 如下图所示，点击按钮进入 Lakehouse 服务实例：

-
-6. 开始配置同步任务的必填信息，核心是配置来源和目标端的信息。
-   备注：此处需要理解“数据源”概念。“数据源”是定义外部服务连接信息的对象，包括服务地址、认证信息、连接方式等。定义好的数据源可以在数据同步任务中作为数据来源或数据目标使用。
-
-7. 源端配置如下图所示，点击“+”后可以快速唤起新建数据源的界面：
-
-   ![](.topwrite/assets/image_1748337608071.png)
-
-8. 选择需要导入的数据源类型，本示意中选择 MySQL，点击“下一步”进入详情配置页面。右上角的“使用说明”中，配套了详细的配置指南，如下图所示。请确保填写的 JDBC 连接地址、用户名和密码正确。serverTimezone 配置项是指数据库所在的时区，会影响同步到目标端后日期和时间字段的取值，请根据实际情况正确选择。
-
-   ![](.topwrite/assets/image_1748337616322.png)
-
-9. 完成数据源的必填信息配置后，可以点击“连通性测试”按钮来测试数据源是否可以连通访问。测试连通正常如下图所示。如果不能连通，请检查网络和配置信息是否准确。测试通过后，点击右下角的确定进行保存。
-
-   ![](.topwrite/assets/image_1748337623157.png)
-
-10. 完成数据源创建后，回到同步任务配置页面，选择该数据源作为源端（如果没有自动展示，请重新打开任务），并选择命名空间（即数据库）和数据对象（即表），其他配置项可留空。
-
-    ![](.topwrite/assets/image_1748337630413.png)
-
-11. 完成源端配置后，进行目标端的配置，如下图所示：
-
-    ![](.topwrite/assets/image_1748337636870.png)
-
-    1\). 选择Lakehouse数据源类型
-
-    2\). 选择内置的 quick_start 工作空间（可类比理解为 database）。
-
-    3\). 选择 public 命名空间（即：schema）
-
-    4\). 数据对象，可以通过 + 按钮，快速新建目标Lakehouse表，在弹框中核对表的命名和schema信息后，点击“确定”按钮，完成表的创建。
-
-    ![](.topwrite/assets/image_1748337664468.png)
-
-    5\). 数据写入模式选择“覆盖写入”，即在同步前会先清空目标表中的数据，再写入从源端获取的数据。
-
-12. 完成上述步骤后，在“字段映射配置”中会自动展示源端表和目标表的字段映射关系（默认是同名映射）。此处使用默认方式即可，无需修改。
-
-    ![](.topwrite/assets/image_1748337679341.png)
-
-13. 其他配置项，例如同步规则配置、高级配置等，使用默认值即可。
-
-    ![](.topwrite/assets/image_1748337686553.png)
-
-14. 点击任务配置区域上方的“保存”按钮，保存任务的全部配置。
-
-    ![](.topwrite/assets/image_1748337694348.png)
-
-15. 点击右上角的“运行”按钮，运行测试并触发数据同步（集群选项使用默认值即可）。
-

-16. 在页面右下角的“运行历史”区域，可以查看到任务的运行情况。
-
-    注：如果想测试同步速度，建议使用数据量相对较大的表进行测试，以降低任务启动时间带来的影响。
-
-    ![](.topwrite/assets/image_1748337713243.png)

-
-### 业务需求
-
-本例中的业务需求模拟电商场景中常见的 BI 分析需求场景，通过用户行为日志数据，关联商品、店铺、时区等维度表数据，生成一张数仓明细层的宽表，提供给下游数据应用层，再通过 BI 工具进行销售额、订单数统计，漏斗转化模型、热门商品展示等。
-
-![](.topwrite/assets/image_1692975150801.png =704)
-
-^
-
-整体的工作流构建思路是：
-
-完成这 4 张表的数据集成任务创建&#x20;
-
-\>>&#x20;
-
-创建 4 张 Lakehouse 目标表，1 张业务实时表，和 3 张维度表&#x20;
-
-\>>&#x20;
-
-创建数据开发任务
-
-\>>&#x20;
-
-通过 SQL 关联查询，将四张表的字段融合成一张宽表，写入一张 DWD 层的结果表&#x20;
-
-\>>&#x20;
-
-按照数据集成任务在前，SQL 任务在后的顺序配置任务依赖关系&#x20;
-
-\>>&#x20;
-
-将所有的任务提到到生产环境。

-
-### 回顾准备工作
-
-参考上一章节的**准备工作**，在“快速开始”之前，您需要确保您所在的企业已经开通了云器 Lakehouse 服务，可以登录到 Studio 产品首页。

-#### 【配置数据源】
-
-Studio 提供的新建数据源的方式有两种：
-
-* 方法一：按照 ① \[管理] → ② \[数据源] → ③ \[新建数据源] 的步骤可以新建数据源；
-* 方法二：通过 ① \[开发] → ② \["✙" 按钮] → ③ \[离线同步] → ④ \["✙" 按钮] 的方式也可以新建数据源。
-
-^
-
-图1 —— 方法一
-![](.topwrite/assets/image_1692588245122.png =785)
-
-^
-
-图2 —— 方法二
-![](.topwrite/assets/image_1692588445515.png =719)
-
-^
-
-![](.topwrite/assets/image_1692589881885.png =676)
-
-^
-
-在新建数据源页面选择 MySQL 类型数据源，点击下一步。
-
-![](.topwrite/assets/image_1692605359674.png =399)
-
-^
-
-输入数据库连接信息，点击连通性测试，如果配置正确，会显示绿色的 \[√连接正常]，如果连接测试失败，则需要核对配置信息，或更改数据库的访问白名单策略。\*如果需要定向添加 IP 白名单，请联系云器客服或客户经理。
-
-![](.topwrite/assets/image_1692605303319.png =553)
-
-^
-
-创建成功后可在列表中看到该数据源。
-
-![](.topwrite/assets/image_1692605636158.png =733)
-
-^
-
-####
-
-#### 【创建数据集成任务】
-
-让我们回到 \[开发] 菜单，创建一个 \[离线同步任务]
-
-![](.topwrite/assets/image_1692588445515.png)
-
-这里的任务名称暂时命名为 “MYSQL数据集成任务”，点击确定。
-
-![](.topwrite/assets/image_1692605970219.png =658)
-
-在 ① 的列表处可见刚才创建的任务，点击 ② 处选择数据源类型为 ③ 处的 MYSQL，并选择到我们刚才创建的数据源名称：BizData\_Demo
-
-![](.topwrite/assets/image_1692606182111.png)
-
-在 ① 处选择库，在 ② 处选择表，在 ③ 处添加过滤条件，点击 ④ 处的按钮可以进行数据的预览。*splitPk 是用于多并发抽取数据用的切分键，需要根据数据库中表 INT 类型主键进行数据分割，非必要项，此处不做深入演示*。
-
-![](.topwrite/assets/image_1692608687809.png =764)
-
-点击 \[预览] 按钮后，会根据配置的过滤条件预览少量数据。
-
-![](.topwrite/assets/image_1692608871867.png =668)
-
-由于我们是从 MySQL 数据源向云器 Lakehouse 进行数据同步，那么目标端数据源自然是选择 Lakehouse 类型，如下图 ① → ② → ③ 步骤所示
-
-![](.topwrite/assets/image_1692609388901.png)
-
-① 处的命名空间可以先选择默认的 public，数据对象由于是首次创建任务，还没有在 Lakehouse 端进行建表，所以 ② 处提供了贴心的一键建表功能。
-
-![](.topwrite/assets/image_1692610106739.png =490)
-
-在弹出的一键建表窗口，如果点击 \[确定] 按钮，会直接创建 Lakehouse 表；此外，还支持复制建表语句，方便用户进行修改后单独做创建操作。
-
-^
-
-***注意***：*一键建表的 DDL 语句创建的不是【分区表】，不带分区字段。如果您希望在 Lakehouse 中创建分区表，请修改建表的 DDL 语句。分区表创建语法详见【SQL 参考】章节*。
-
-^
-
-![](.topwrite/assets/image_1692610369991.png =656)
-
-^
-
-创建目标表后会在 ① 处数据对象直接选中该表，② 处的计算集群无需改动，默认选择 default 集群，③ 处输出模式选择上，由于我们做全量数据同步，因此一般会选择 ④ 处的 \[写覆盖] 模式。
-
-![](.topwrite/assets/image_1692610656866.png =480)
-
-^
-
-在选择完源端表和目标端表之后，下面的字段映射配置会显示出来。① 处支持直接修改目标端字段名，② 处支持开启该行字段的映射或暂时关闭（其他字段不受影响），③ 处支持删除单行的字段映射，用于减少一些明确的无用字段。
-
-^
-
-![](.topwrite/assets/image_1692611229942.png =737)
-
-^
-
-在字段映射底部，也支持手动添加字段，或常量列，手动添加的字段可以重复获取源端表中某字段的值，赋予目标端的某个其他字段，常量列支持在数据同步的同时做一些轻量的处理和转换，可以给目标端字段赋值固定值，或函数表达式。本例中不涉及此操作，因此不予以演示。
-
-^
-
-![](.topwrite/assets/image_1692611971563.png =717)
-
-^
-
-那么万一字段映射填写错乱了，想要重置字段映射关系该怎么办？在这里我们也贴心准备了重置刷新等功能，分别是 ① 同名映射 ② 重置刷新 ③ 清除映射 ④ 全屏化。
-
-^
-
-![](.topwrite/assets/image_1692868770187.png =637)
-
-^
-
-任务配置完成后，位于 ① 处的 \[保存] 可对任务进行保存，位于 ② 处的 \[版本] 可以查看历史版本信息，这里不再赘述。值得一提的是位于 ③ 处的 \[调度] 配置完成后，可以解锁后面的 \[提交] 按钮，只有任务提交到生产环境了，才会根据调度的配置进行作业的调度，因此在任务 \[提交] 后会解锁 \[运维] 按钮。
-
-^
-
-但在任务保存之后，我们通常会点击位于 ④ 处的 \[运行] 按钮，尝试手动运行任务，完成数据的初始化集成。
-
-^
-
-![](.topwrite/assets/image_1692869115260.png =807)
-
-点击 \[运行] 启动任务以后，① 处的 \[运行] 按钮会变成  \[停止] 按钮，下方的运行历史会增加一个条目，在 ② 处标记了正在运行的任务实例，右侧的操作栏下，一般查看位于 ③ 处的 \[日志] 即可查看任务运行详情。
-
-^
-
-![](.topwrite/assets/image_1692869694189.png)
-
-^
-
-日志信息如下所示：
-
-^
-
-![](.topwrite/assets/image_1692869803721.png)
-
-^
-
-接下来等待任务完成即可。至此，数据已经写入云器 Lakehouse 了。
-
-^
-
-![](.topwrite/assets/image_1692877068479.png =426)
-
-^
-
-#### 【配置调度依赖】
-
-我们先别急着去查看数据条数，继续完成调度上的配置。点击上边功能菜单的 \[调度] 按钮，右侧滑出调度菜单，我们下拉快进到 \[调度时间] 部分：在离线 T+1 场景中，调度周期配置为 \[每天调度] 、\[执行一次]、\[00:00 开始调度]、当天开始生效、\[永不失效] 即可。
-
-^
-
-其中 ① 处还可以选择为 \[每月指定天]，\[每周指定天] 的方式，② 处可以选择为 \[执行多次] X 分钟的调度周期间隔。
-
-^
-
-在 \[实例信息] 部分，由于我们刚刚已经运行过任务了，那么位于 ③ 处的实例生成方式可以选择为 \[次日生效]。（注意：每日多次的任务在发布后要选择 \[发布后生效]，否则要等到第二天才会开始运行）
-
-^
-
-\[实例遇错重跑]，则是处理任务报错重跑的策略，通常我们选择 \[运行成功或失败后皆可重跑] 即可，这里不作过多赘述。
-
-^
-
-![](.topwrite/assets/image_1692877280440.png =752)
-
-^
-
-最后我们来到 ① \[调度依赖] 和 ② \[任务产出] 这部分，配置完成后我们点击 ③ \[确定] 按钮，即可解锁 \[提交] 按钮了，就具备将任务提交到生产环境进行作业调度的条件了。
-
-^
-
-关于 \[调度依赖]，我们都知道一个标准的数仓处理过程都是从数据的接入开始的，所以数据集成任务通常作为整个链路的起始节点，是没有上游依赖任务的，因此位于 ① 处的 \[调度依赖] 此处不作任何设置。当然数据集成任务一般也不会长达一天的时间，因此下方的 \[自依赖] 也无需勾选。
-
-^
-
-![](.topwrite/assets/image_1692929739481.png =450)
-
-^
-
-关于 \[任务产出]，首先要解释一下任务产出是做什么用的：当前完成配置的数据集成任务的作用是把源端数据库对应表的数据写入目标端的目标表，因此在整个调度系统中，需要宣称这个目标表是被这个任务所“生产出来”的，即“任务产出”。
-
-^
-
-此处所定义了的任务产出的表名，不单单必须是目标表的“物理真名”，也可以是人为更改的其他“别名”，甚至是多个不同的别名。其最主要的作用是使该任务所产出的表可以在整个调度依赖系统中被其他任务搜索到，从而形成上下游的依赖关系。其最大的应用则是在调度系统中可以被其他任务所依赖。
-
-^
-
-因此，这里提供了人工自定义添加表名，和系统 \[智能解析] 功能按钮。本例中，不做别名的特殊调整，所以直接选择 \[智能解析] 即可，如图所示。
-
-^
-
-![](.topwrite/assets/image_1692930975096.png =513)
-
-^
-
-完成配置后点击 \[确定]，解锁 \[提交] 按钮。
-
-^
-
-![](.topwrite/assets/image_1692931241963.png =498)
-
-^
-
-#### 【提交发布任务】
-
-点击 \[提交] 按钮，会弹出与历史版本对比的确认窗口，本例中是首次提交，直接点击 \[确定] 即可。
-
-![](.topwrite/assets/image_1692931416038.png =564)
-
-^
-
-提交成功后会弹出提示，并且任务状态会改变：\[未提交] → \[已提交]
-
-![](.topwrite/assets/image_1692931479995.png =432)
-
-^
-
-至此，一个数据集成任务就发布完成了。
-接下来我们可能会有两个疑问：
-1、刚才同步了数据，我是不是要查看一下数据量对不对，并进行一下预览；
-2、数据集成任务发布到调度系统中去了，怎么去运维和查看这些任务。
-针对以上的 2 个问题，我们分别会在接下的【数据开发】章节与【任务实例运维】章节进行讲解。
-
-^
-
-#### 【创建数据开发任务】
-
-按图所示创建 SQL 任务，可以进入到 SQL 的 编辑器页面，我们先进行一些基本的数据探查，比如核对一下刚刚接入表的数据量，预览一些数据等等。
-
-![](.topwrite/assets/image_1692947107206.png =417)
-
-^
-
-任务名称暂定为 “SQL数据开发任务”，点击确定。
-
-![](.topwrite/assets/image_1692947166405.png =317)
-
-^
-
-创建成功后进入 SQL 编辑器，功能按钮与数据集成任务大致相同，多了 \[格式化] 按钮用于美化 SQL。
-
-![](.topwrite/assets/image_1692947217040.png =688)
-
-^
-
-通过统计表条目数语句，查询结果。在 ① 处可以局部 / 单行执行 Query，在 ② 处会全部脚本运行任务，无论用 ① 或 ② 的方式，运行都是在 ③ 处查看结果。
-
-![](.topwrite/assets/image_1692953836250.png =678)
-
-^
-
-之后我们再去源端数据库中查询一下这个表的条目数，可以发现两边条目数一致。（别忘了我们再数据集成的 \[筛选] 处添加了 event\_id is not null，在查询源端数据库时也要加上这个条件）
-
-![](.topwrite/assets/image_1692954920520.png =513)
-
-^
-
-好的，两边数据量一致，再通过类似以下的脚本来预览一下数据，看看数据格式是否都正确等等。
-
-```
-select * from tablename[你的表名] limit 10
-```
-
-^
-
-截止到这一步，基本的数据探查已经完成，接下来我们来构建整个工作流。
-
-^
-
-让我们再来确认一下业务目标：我们按照从左到右的顺序，已经完成了数据源的配置，并且学会了如何创建数据集成任务和数据开发任务。
-
-![](.topwrite/assets/image_1693020935459.png =610)
-
-^
-
-那么，我们只需要重复多次【创建数据集成任务】，就可以将这 4 张表创建出来，并将数据接入到云器 Lakehouse。
-
-^
-
-通过任务名称右侧的 \[更多] 选项中的 \[复制] 功能，可以快速复制出 4 个来自相同数据源的任务，再略微修改配置，一键创建目标表，可以非常方便地完成任务的创建。
-
-![](.topwrite/assets/image_1693016680123.png =329)
-
-^
-
-复制出来的任务名默认是在原有任务名上增加 “\_copy”，这里只需要按需改成我们想要的名字即可。
-
-![](.topwrite/assets/image_1693016822970.png =294)
-
-^
-
-接下来，修改数据开发任务中的脚本内容，完成 user\_log 表与 shop、goods、timezone 3个维度表的关联查询，并将结果写入 dwd\_user\_charac，如果是首次创建表，可以使用 create table xxx as select... 的语句，单独运行一次即可。当然如果需要每天进行任务调度的话，最终提交的任务中，写入方式应该是 \[覆盖写入]（insert overwrite）。
-
-![](.topwrite/assets/image_1693034692564.png =577)
-![](.topwrite/assets/image_1693034727649.png =547)
-
-^
-
-通过模糊检索选择上游的调度依赖。
-
-![](.topwrite/assets/image_1693186498403.png)
-
-^
-
-我们直到所有的数据集成任务都完成后才能执行 SQL 加工任务，因此添加四次上游任务即可。
-
-![](.topwrite/assets/image_1693188053947.png =354)
-
-^
-
-其他的配置与上面讲过的方法一样，最后别忘了 \[保存] 和 \[提交]，所有提交后的任务图标应该是带有绿色圆圈上角标的样式。
-
-![](.topwrite/assets/image_1693188429895.png =217)
-
-^
-
-好的，至此，我们已经完成了所有数据集成任务和数据开发任务的创建，并且已经运行过了一轮任务。接下来，我们介绍一下如何去 \[运维中心] 中查看这些任务实例及血缘关系。
-
-^
-
-#### 【任务运维】
-
-^
-
-任务提交到生产之后，我们来介绍一下基础的运维工作。通过左边菜单栏点击 ① 处的 \[任务运维] 进入到运维中心。按照上面 ②③④⑤ 的页签，分别表示了 \[周期任务]、\[实时任务]、\[补数任务]，以及 \[任务实例]。
-
-^
-
-当我们点击进入【任务运维】功能模块时，页面默认跳转到的是 ④ 的 \[任务实例]，因为运维人员一般关心的就是任务实例每天的运行状态和运行结果如何。而任务实例分为 ⑥ \[周期实例]、⑦ \[临时实例] 两种，任务实例的运行状态有：⑧ \[运行成功]、⑨ \[运行中]、⑩ \[运行失败] 3 种。
-
-^
-
-![](.topwrite/assets/image_1693193833131.png)
-
-^
-
-这里我们要理解【任务】和【实例】的区别：任务是指一种预设的工作流程配置，而实例则是将这些工作流程配置的实例化，也就是实际执行的事例。
-
-^
-
-我们点击周期任务这个页签，查看我们发布的 SQL 数据开发任务，可以进入到任务详情页面。
-
-![](.topwrite/assets/image_1693202818256.png)
-
-^
-
-任务详情页面除了自身的信息 ①\[任务详情] 以外，还提供 ② \[任务实例]、③ \[节点代码]、④ \[操作日志] 的查看页签，这里仅展示任务详情页签。
-任务详情上半部分展示的是任务的一些元数据信息。
-
-![](.topwrite/assets/image_1693203132344.png)
-
-^
-
-下半部分则展示的是该任务与上下游任务之间的依赖关系。
-
-![](.topwrite/assets/image_1693202961210.png)
-
-^
-
-那么上面是任务的详情，在实例的详情中一样可以看到实例的运行状态，和任务详情相似，不同的是节点展示的是实例的实际运行情况，并支持对实例进行一些置成功、置失败、重跑等操作，这里一样不加以赘述了。
-
-^
-
-#### 【连接 BI 工具】
-
-根据上面的内容，我们假设现在所有的数据准备工作已经完成，下一步就是数据的应用了，在本例中数据仓库加工后的数据最终展示在 BI 看板上。
-
-^
-
-首先我们要了解的一点是，云器 Lakehouse 提供了丰富的 SDK，允许 BI 工具通过 JDBC 或 Python SqlAlchemy 直接连接访问 Lakehouse，因此市面上常规的 BI 工具，如：帆软 BI、SuperSet、Tableau、衡石 BI、Power BI 等大多都可以支持。
-
-^
-
-以帆软 BI 为例，首先我们可以到 < [JAVA SDK 简介](java_reference/java-sdk-summary.md)>  章节处获取 JDBC Driver 。
-
-![](.topwrite/assets/image_1693290887172.png =251)
-
-^
-
-下载到 JAVA SDK 后，我们需要在帆软 BI 的系统设置中将这个 Driver 添加到第三方数据连接驱动中。
-帆软 BI 稍微特殊一些，默认是不允许用户本地上传驱动的，需要打开后台的开关。操作步骤参见官网文档：
-<https://help.fanruan.com/finebi/doc-view-1540.html>
-
-^
-
-在获准管理驱动之后，我们通过系统设置进入到数据连接管理。
-
-![](.topwrite/assets/image_1693207507345.png =752)
-
-^
-
-在右侧的页面中选择 \[驱动管理] → \[新建驱动]
-
-![](.topwrite/assets/image_1693207760197.png =247)
-
-^
-
-驱动名称可以自定义命名。
-
-![](.topwrite/assets/image_1693207884575.png =284)
-
-^
-
-按图上 ① 处上传文件，文件上传及解析后在 ② 处点选 ③ 的类。
-
-![](.topwrite/assets/image_1693208001316.png =687)
-
-^
-
-点击右上角进行驱动的保存。
-
-![](.topwrite/assets/image_1693208098173.png =625)
-
-^
-
-配置完成后，我们退回到数据连接管理，就可以新建 Lakehouse 的数据源了。
-
-![](.topwrite/assets/image_1693209222368.png =223)
-
-^
-
-由于我们目前还属于第三方连接驱动，因此我们选择 \[其他] → \[其他 JDBC]
-
-![](.topwrite/assets/image_1693209282780.png =516)
-
-^
-
-在这里，我们选择驱动类型中的 \[自定义]
-
-![](.topwrite/assets/image_1693209346360.png =415)
-
-^
-
-如果找得到我们刚才添加的驱动选项则直接选择，如果找不到则点击右侧的 \[添加驱动]
-
-![](.topwrite/assets/image_1693209431798.png =690)
-
-^
-
-我们仅需要定义一个 \[数据库名称]，以及填写 \[用户名]、\[密码]、 \[数据连接 URL] 等信息。不清楚 URL 如何填写的用户，可以查看帮助文档的 SDK 章节，或联系你们的客户经理。
-
-![](.topwrite/assets/image_1693209540889.png =385)
-
-^
-
-填写后点击 \[测试连接]，如果配置正确会显示【连接成功】，点击 \[保存] 按钮完成创建。
-
-![](.topwrite/assets/image_1693209771680.png =723)
-
-^
-
-如果连接名称显示受 URL 影响，也可以通过 \[重命名] 的方式进行自定义。
-
-![](.topwrite/assets/image_1693211182568.png =342)
-
-^
-
-数据连接创建成功后，BI 工具就可以像访问其他数据库一样访问 云器 Lakehouse 了。基于数据源创建数据集，添加数据库表，就可以访问 Lakehouse 中的表了。
-
-![](.topwrite/assets/image_1693211916144.png =297)

-
-![](.topwrite/assets/image_1693212056036.png =651)
-
-创建仪表板引用数据集进行编排，感兴趣的同学可以参考帆软 BI 的帮助文档。
-<https://help.fanruan.com/finebi/>
-
-^
-
-通过一定的看板样式设计，我们可以做出丰富多彩的 BI 看板了。

-# 入门指南：如何快速新建和使用工作空间
-
-## 适用场景
-
-工作空间是用于组织 Lakehouse 资源对象（数据对象、计算资源、用户等），并提供配套的数据开发能力（数据集成、数据开发、数据运维）的逻辑对象。完成注册登录、开通Lakehouse产品后，在服务实例下会默认初始化出来一个名为 `quick_start`的工作空间。这个工作空间里也内置了一些样例数据和样例代码，您如果计划基于该工作空间来使用产品功能，可以跳过此文档，建议您参考以下文档来开始使用产品：
-
-* [如何快速运行一个SQL](quick_start_sql_query.md)
-* [如何快速上传导入数据](quick_start_upload_data.md)
-
-如果您想创建更多的工作空间来满足不同的使用场景的需要，比如按照业务来区分工作空间或者按照数仓规划的分层来组织工作空间，可阅读此文档。

-# 入门指南：如何快速配置和使用数据质量规则
-
-## 适用场景
-
-数据质量规则用于校验数据对象的质量是否符合要求，比如数据的正确性、有效性和一致性等，尤其是对于服务于生产使用的任务产出的数据表。如果您配置了ETL流程，比如前文的 [入门指南：如何快速配置编排和周期调度ETL流程](quick_start_etl.md)，计划对数据的质量增加一个检查，建议阅读此指南。
-
-## 前置阅读
-
-在阅读本指南之前，建议完成以下文档的阅读和理解：
-
-* [Lakehouse 产品简介](what_is_clickzetta_lakehouse.md)
-* [产品基本概念](Key_Concepts.md)
-* [Lakehouse Studio 快速导览](LakehouseStudioTour.md)
-
-## 操作指南
-
-您可以通过 Lakehouse Studio 提供的「数据质量」功能来配置质量规则进行检查。检查主要基于数据质量规则来进行。规则会预先定义校验的对象、检查逻辑和预期结果，并可以通过多种方式触发运行。本示例展示如何为一张 Lakehouse 表的字段配置规则，以校验其取值非空。
-
-### 使用说明
-
-* 具备 `工作空间管理员角色（workspace_admin）` 或 `工作空间开发角色(workspace_dev)` 的用户，有权限使用「数据质量」功能。
-* 「数据质量」功能目前主要用于监控 Lakehouse 的数据对象，比如 Table、View、Volume、Dynamic Table 等，对于 MySQL 等其他数据类型，暂不支持。
-
-### 操作步骤
-
-1. 如下图所示，点击按钮进入 Lakehouse 服务实例：
-
-   ![](.topwrite/assets/image_1748337538227.png)
-
-2. 导航到「数据」>「数据质量」页面：
-
-   ![](.topwrite/assets/image_1749449999835.png)
-
-3. 在“质量规则”Tab页，点击“新建规则”按钮，打开新建质量规则的页面。请注意核对，确保页面右上角的工作空间是需要校验的数据表所在的工作空间。如果不是，可以点击后进行切换。
-   ![](.topwrite/assets/image_1749450019542.png)
-
-4. 在新建规则页面，工作空间的值会自动设定为上一步选择的工作空间【1】。选择需要校验的数据对象。本示例中，选择先前ETL流程中同步任务导入数据写入的 `test_json` 表进行校验【2】。质量规则执行时，实际上会转化为 Lakehouse SQL 语句执行，因此需要一个执行集群。为简单起见，建议直接选择默认的 GP 类型集群 `DEFAULT`【3】。
-   ![](.topwrite/assets/image_1749450038105.png)
-
-5. 配置“校验方式”、“触发方式”并“保存”规则。
-
-   * 校验方式【4】：本示例中我们计划监控 test_json 表中的 c1_id 字段取值非空，所以选择“单值指标取值校验”即可；“指标取值变动校验”会比较两个指标，并校验变化值。产品内置了诸多指标规则，开箱即用。这里选择字段空值数、选定字段名称、期待结果设定为等于0。
-
-   * 触发方式【5】：如字面含义，产品提供定时触发、周期调度任务触发和手动触发三种方式。周期任务触发会与调度系统绑定，在任务调度实例运行完成后即可触发质量规则的执行，能使校验更及时。对于生产场景，推荐使用这种方式。尤其是“强阻塞调度”选项，可以在质量规则校验失败时，阻塞整个调度流程，防止质量问题扩散。选择这种方式时，需要选择绑定的调度任务（即产出该数据表的任务）。
-
-   * 其他配置项保留默认值或留空即可。最后点击“保存”【6】按钮，完成质量规则的新建。
-
-   ![](.topwrite/assets/image_1749450069308.png)
-
-6. 创建完成后，在质量规则列表页面可以看到新增的规则。
-   ![](.topwrite/assets/image_1749450081238.png)
-
-7. 可以点击“试跑”按钮来测试质量规则的配置和校验情况。在“校验结果”Tab页可以查看具体结果，如下图所示：质量规则被触发运行，校验结果与预期一致，一切正常。
-   ![](.topwrite/assets/image_1749450092151.png)
-   ![](.topwrite/assets/image_1749450096317.png)
-
-8. 等待调度任务的定时到达后，观察质量规则触发情况。
-
-   * 在「任务运维」中，通过周期任务实例运行的日志，可以查看质量规则的触发运行情况。
-     ![](.topwrite/assets/image_1749450116093.png)
-
-   * 在「数据质量」的“校验结果”中，可以看到新增的校验记录，触发方式为“周期任务触发”。
-     ![](.topwrite/assets/image_1749450124984.png)
-
-9. 至此，已经完成了质量规则的配置和校验运行情况的观察。在完成数据质量规则配置后，如果需要及时收到质量规则校验失败的监控告警信息，还需进行监控配置，具体操作在此略过，详见 [数据质量](DataQuality.md) 的帮助文档。
-
-## 相关文档
-
-* 您可以阅读 [数据质量](DataQuality.md) 的帮助文档来了解数据质量模块的完整使用指南。
-
-## 下一步建议
-
-* 完成质量规则的配置后，可以参考 [如何快速配置和使用监控告警规则](quick_start_monitoring_and_alerting.md) 的指南文档，对质量规则的校验结果和任务运行状态等，配置监控规则、发送告警。

-# 入门指南：如何快速配置编排和周期调度ETL流程
-
-## 适用场景
-
-数仓工程师主要工作之一是构建离线数仓，即创建和维护周期调度ETL流程。本文会概要介绍如何基于 Lakehouse Studio 来配置和编排 ETL 任务，并配置调度属性，使得整个 ETL 流程能够被定时、按照依赖关系调度运行。
-
-## 前置阅读
-
-在阅读本指南之前，建议完成以下文档的阅读和理解：
-
-* [Lakehouse 产品简介](what_is_clickzetta_lakehouse.md)
-* [产品基本概念](Key_Concepts.md)
-* [Lakehouse Studio 快速导览](LakehouseStudioTour.md)
-
-## 操作指南
-
-在 [入门指南：如何快速创建同步任务来导入数据](quick_start_batch_sync_data.md) 中，我们已经创建了一个数据同步任务。本文档将以示例的方式，继续创建一个 SQL 处理任务，并让其依赖于该数据同步任务，从而构建出一个 ETL 流程，并配置调度定时来定期运行。
-
-### 使用说明
-
-需要具备 `工作空间管理员角色（workspace_admin）` 或者 `工作空间开发角色(workspace_dev)` 权限的用户，才能使用任务开发、提交发布和运维中心的功能。
-
-### SQL任务的创建
-
-1. 通过下图的操作入口，来创建一个 SQL 任务：
-
-   ![](.topwrite/assets/image_1748425848352.png)
-
-2. 在创建任务的弹框中，将任务命名为“SQL_DWS_聚合”，并单独创建一个名为“数据处理”的文件夹。
-
-   ![](.topwrite/assets/image_1748425859150.png)
-
-3. SQL 任务新建好后，如下图所示，在编辑区可以编写具体的 SQL 代码。
-
-   ![](.topwrite/assets/image_1748425869532.png)
-
-4. 前面通过数据同步任务，已经把 MySQL 的数据同步到 Lakehouse 的 test_json 表中。在 SQL 任务中，基于这张表中的数据进行聚合处理，比如把表中的 c2_tinyint_column、c3_smallint_column 两个字段分别求和。导航到“数据” Tab 页，定位到目标表 test_json，然后在操作栏中点击“数据查询”，可以自动将 SELECT 代码模板插入到编辑器中，如下图所示，这有助于提升代码编写效率。
-
-   ![](.topwrite/assets/image_1748425911494.png)
-
-5. 基于上述代码模板修改为所需的处理逻辑，然后保存。此处仅为示意，进行了简化处理，聚合结果未写入新表。
-
-   ![](.topwrite/assets/image_1748425934078.png)
-
-   ```SQL
-        SELECT   SUM(c2_tinyint_column),         
-                 SUM(c3_smallint_column),
-        FROM     test_json;
-   ```
-
-### 任务编排和调度配置
-
-完成同步任务和 SQL 任务的创建后，要构建完整的离线周期处理 ETL 流程，还需要配置调度定时和任务依赖关系。
-
-1. 打开同步任务，通过页面的“调度”按钮，打开调度属性的配置。
-
-   ![](.topwrite/assets/image_1748426012421.png =633)
-
-2. 配置调度时间：配置成每天调度、执行多次、每一个小时调度一次，如下图所示。通过“预览调度时间”可以查看基于配置对应的具体定时时间。
-
-   ![](.topwrite/assets/image_1748426023159.png =722)
-
-   ![](.topwrite/assets/image_1748426030471.png =397)
-
-3. 配置实例信息：这里主要需要配置“实例重跑方式”。由于本任务不存在重跑后产生数据不幂等的问题，可以重跑，因此选择“运行成功或失败，都可以重跑”，其他属性使用默认值即可。
-
-   ![](.topwrite/assets/image_1748426041609.png =386)
-
-4. 配置调度依赖：同步任务是流程中的第一个任务，没有上游依赖，此处留空即可。
-
-   ![](.topwrite/assets/image_1748426049779.png =386)
-
-5. 配置任务产出：任务产出用于描述本任务写入的是哪张表，以便下游任务在消费此表时，能智能识别到对应的上游任务。点击“智能解析”按钮，系统会通过任务配置自动解析出当前任务的产出表并回填到配置中。
-
-   ![](.topwrite/assets/image_1748426056766.png =386)
-
-6. 完成上述调度配置后，点击页面右下角的“确定”按钮将配置保存。回到任务页面，如下图所示，“提交”按钮会变成可点击的状态。
-
-   ![](.topwrite/assets/image_1748426062758.png)
-
-7. 点击“提交”按钮，在弹窗中二次核对信息无误后，再点击确定，同步任务即被提交到生产环境进行定期调度运行。
-
-   ![](.topwrite/assets/image_1748426068998.png)
-
-8. 切换到 SQL 任务，通过页面的“调度”按钮，打开调度属性的配置，需要配置的属性和同步任务相同，即：
-
-      1. 配置成一天调度多次、每小时调度一次。
-      2. 重跑属性配置成“运行成功或者失败，都可以重跑”。
-      3. 请特别注意需要配置 SQL 任务对同步任务的依赖关系。点击页面上的“智能解析”按钮，会自动识别 SQL 任务所依赖的同步任务并自动回填；也可以手动添加。
-      ![](.topwrite/assets/image_1748426078453.png =386)
-
-9. 同上，SQL任务的调度配置完成后，点击页面右下角的“确定”按钮将配置信息保存下来。回到任务页面，点击“提交”按钮把SQL任务也提交做定时调度。
-
-   ![](.topwrite/assets/image_1748426087176.png)
-
-10. 进入“任务运维”查看实际效果，有两种方式进入：
-
-    * 方式一：通过左侧导航 运维监控 > 任务运维
-
-    * 方式二：在任务上直接点击“运维”按钮，可直达运维中心中该任务的详情页，建议使用此方式。
-
-      ![](.topwrite/assets/image_1748426094142.png)
-
-11. 查看任务的详情，如下图所示，和预期一致，SQL任务依赖了同步任务：
-
-    ![](.topwrite/assets/image_1748426100418.png)
-
-12. 点击“任务实例”Tab，可以看到任务对应的具体实例的列表，实例已按照配置的定时时间生成（只生成任务提交时间之后的实例）：
-
-    ![](.topwrite/assets/image_1748426139524.png)
-
-13. 点击实例 ID 可以进入实例的详情页面进行查看。在定时时间到达后，上游的同步任务实例先运行，运行成功后，下游的 SQL 任务实例才会开始运行。实例触发运行需要同时满足两个条件（充分必要条件）：实例自身的定时时间已到达，且上游实例处于运行成功状态。
-
-    ![](.topwrite/assets/image_1748426146577.png)
-
-14. 至此就完成了一个完整的ETL流程的编排构建，并提交进行周期调度、运行。
-
-## 限制说明
-
-* 权限控制：需要具备 `工作空间管理员角色（workspace_admin）` 或者 `工作空间开发角色(workspace_dev)` 权限的用户，才能使用任务开发、提交发布和运维中心的功能。
-
-## 相关文档

-* [产品基本概念](Key_Concepts.md)
-* [Lakehouse Studio 快速导览](LakehouseStudioTour.md)
-
-## 操作指南
-
-Lakehouse Studio的「监控告警」产品模块，提供了一套强大的功能，它允许用户通过系统内置的规则或自定义规则，对任务运行状态等关键指标进行实时监控。一旦检测到异常情况，系统将发送及时的告警通知，帮助您确保数据流的稳定性和可靠性。
-
-### 使用说明
-
-具备 `工作空间管理员角色（workspace_admin）`、`工作空间开发角色(workspace_dev)` 或者 `工作空间运维角色(workspace_sre)` 的用户，可以使用「监控告警」功能。
-
-### 操作步骤
-
-#### 进入监控告警模块
-
-1. 如下图所示，点击按钮进入Lakehouse服务实例：
-   ![](.topwrite/assets/image_1748337538227.png)
-
-2. 导航到「运维监控」>「监控告警」页面：
-   ![](.topwrite/assets/image_1749455648524.png)
-
-#### 使用内置规则
-
-如上文所述，产品内置了全局的监控规则可供选择启用。
-
-1. 如下图所示，主要内置了“周期任务实例运行失败”和“数据质量检测失败”两类监控规则：
-
-   ![](.topwrite/assets/image_1749455660655.png)
-
-2. 点击具体的监控规则，可以查看其详细的配置定义。以“数据质量检测失败-强规则”为例，下图展示了其监控事项、告警通知方式和通知人员等核心信息。
-   ![](.topwrite/assets/image_1749455672982.png)
-
-   * 监控事项：强阻塞调度的质量规则校验失败。
-   * 告警通知：严重等级的规则，按照通知策略的定义（此处不展开，详见相关文档），会通过电话推送告警。
-   * 通知人员：默认会通知给对象责任人。对于数据质量规则，默认通知给规则创建人。
-
-3. 启用内置的全局告警规则和订阅，继续以“数据质量检测失败-强规则”为例：
-   ![](.topwrite/assets/image_1749455707588.png)
-   * 点击“开启”即可启用此规则[1]。按照规则定义，本告警会通知到对象责任人，即质量规则的创建人。
-   * 如果您不是对象责任人（比如不是质量规则的创建人），但也想关注此告警，可以点击“订阅”按钮[2]。
-
-#### 自定义监控规则
-
-内置规则主要从全局维度进行整体监控，方便快速使用。但在实际情况下，对于一些特殊对象，也存在单独配置精细化监控的诉求。这种情况下需要使用自定义监控规则的能力。
-
-下面的示例将展示如何监控特定周期调度任务的实例运行失败并通过电话告警，主要操作步骤如下：
-
-1. 在“监控规则”列表里面，点击“新建规则”按钮。
-   ![](.topwrite/assets/image_1749455842124.png)
-
-2. 在新建规则的弹框中，填写规则的必填信息、保存。
-   * 监控事项：任务实例运行失败。通过过滤项，**选择具体的任务名称**。
-   * 告警通知：等级设定为“警告”，选用“通用通知策略”来发送短信告警。通知人员默认会选择当前操作人。
-     ![](.topwrite/assets/image_1749455860120.png)
-     ![](.topwrite/assets/image_1749455865473.png)
-
-3. 规则创建后，在列表中会展示出一条记录：
-   ![](.topwrite/assets/image_1749455912549.png)
-
-4. 观察监控规则的工作情况。
-
-   * 这里进行一次模拟的错误变更：修改被监控任务的SQL逻辑，使用一个错误字段名，然后提交调度运行，以触发一个调度实例运行失败。
-     ![](.topwrite/assets/image_1749455960285.png)
-     ![](.topwrite/assets/image_1749456300165.png)
-
-   * 任务被调度运行、出现失败后，在「监控告警」中可观察到监控告警规则的工作情况，符合预期：
-     * 在“告警事件”中，可以看到新增了一条告警事件：
-       ![](.topwrite/assets/image_1749456335722.png)
-     * 在“通知历史”中，可以看到具体的告警通知推送情况：
-       ![](.topwrite/assets/image_1749456370821.png)
-
-至此，已经完成了监控告警内置规则和自定义规则的配置和实际工作效果观察。
-

-# 入门指南：如何快速运行一条SQL
-
-## 适用场景
-
-Lakehouse 提供了一体化的引擎来支持数据的处理、加工和分析，其开发语言为 SQL。本文概要介绍如何通过Lakehouse Studio的任务开发功能模块快速编写和运行一条SQL语句来进行查询分析。
-
-## 前置阅读
-
-在阅读本指南之前，建议完成以下文档的阅读和理解：
-
-* [Lakehouse 产品简介](what_is_clickzetta_lakehouse.md)
-* [产品基本概念](Key_Concepts.md)
-* [Lakehouse Studio 快速导览](LakehouseStudioTour.md)
-
-## 操作指南
-
-如果要快速在界面运行一条 SQL，需要使用 Lakehouse Studio 的数据开发模块，有两种方式：
-
-### 方式一：基于样例SQL和样例数据来运行
-
-产品中内置了开箱即用的样例代码和与之配套的样例数据。在页面导航，点击“开发”进入数据开发界面后即可看到 `Tpch_100g` 文件夹下的样例代码，这些样例代码演示了如何基于 Tpch\_100g 样例数据来编写SQL进行快速查询分析，如下图所示：
-
-![](.topwrite/assets/image_1747993124883.png)
-
-双击一个样例代码文件打开后，点击页面右上角的“运行”按钮，即可触发 SQL 的执行。执行完成后，在页面右下方可以查看执行结果和日志。
-
-![](.topwrite/assets/image_1747993372483.png)
-
-^
-
-请特别注意页面右上角的**集群**选项。“集群”是“计算集群”的简称，是 Lakehouse 提供算力的核心概念，可参考 [此文档](virtual-cluster.md) 进行详细了解。工作空间创建后，会默认初始化两个集群：名为 `DEFAULT ` 的通用型集群和名为 `DEFAULT_AP ` 的分析型集群。这两类集群针对不同的作业负载有对应的优化：
-
-* 通用型（GENERAL PURPOSE，简称 GP）：适用于处理离线作业，作业之间共享计算资源，新旧作业采用公平调度方式分配计算资源。适用于周期定时调度任务来处理大批量数据。
-* 分析型（ANALYTICS PURPOSE，简称 AP）：具备多计算实例和自动弹缩功能，适合处理在线和高并发作业。如果您想体验更强的数据查询性能，请选择此类型的集群。此外，AP 集群会对数据进行智能缓存。经过第一次查询后，后续查询的速度会更快。下图展示了这个差异：
-
-  ![](.topwrite/assets/image_1748326696659.png)
-
-^
-
-您也可以通过阅读 [使用样例数据快速开始查询分析](sample-data-using.md)，进一步了解如何基于样例数据进行查询分析。
-
-### 方式二：自己编写SQL并运行
-
-除了使用样例代码和样例数据之外，您也可以自己编写 SQL 并运行。在页面导航栏，点击“开发”进入数据开发界面，在“任务”下，通过新建菜单，选择“SQL脚本”来创建一个 SQL 任务文件。
-
-![](.topwrite/assets/image_1721484292583.png)
-
-在任务文件中，可按以下步骤编写和运行 SQL：
-
-1. 在页面上选择正确的数据 Schema。编写代码时，对于该 Schema 下的表的引用，直接写表名即可；否则，需要使用 `schema.table` 两段式或 `workspace.schema.table` 三段式格式来引用表。通常使用系统默认 Schema 即可。
-
-2. 在代码编辑区域填写需要运行的 SQL。
-
-3. 选择恰当的计算集群类型。对于 ad-hoc 临时查询，或者需要获得更快的查询响应速度，建议选择分析型（AP）集群。通用型（GP）集群适合大批量数据的离线、周期性调度任务的处理分析。
-

-
-4. Schema：选择将表创建在某个schema下。
-
-5. 选择表：选择「新建表」并在后方输入新建表名。
-
-6. 集群：当前Schema所在的工作空间下的可用集群。
-
-7. 数据导入方式：支持追加写入，和先清空后写入两种方式导入数据至新建表中。
-
-8. 信息全部确认后，点击“下一步”，系统会基于已上传的文件信息，自动解析出文件中的字段信息，如下图所示。
-   ![](.topwrite/assets/image_1749035692218.png =380)
-
-9. 检查并判断自动解析出来的字段名称和字段类型等信息是否符合预期，确认无误后，点击「确认」即可完成新建表并上传数据的操作。

-# 使用工作空间构建数据开发环境
-
-## 基本概念
-
-工作空间（workspace）是 Lakehouse 产品中的核心概念之一。它用于组织 Lakehouse 资源对象（如数据对象、计算资源），并提供相对隔离的数据开发、调度任务管理和运维环境。
-
-为了实现一个服务实例内的工作空间既相互隔离，又便于进行数据交换，不同工作空间之间的权限相互隔离：一个服务实例用户需要被某个工作空间的空间管理员角色（workspace\_admin）添加进入该工作空间，才可被授权并使用工作空间内的数据或计算资源。
-
-当一个用户具备某工作空间内的数据对象权限时，可以在其他工作空间对这些数据对象进行跨空间的查询或其他权限范围内的操作。
-
-:-: ![](.topwrite/assets/workspace_1735992503899.png =814)
-
-如上图所示，一个 Lakehouse 服务实例内可以创建多个工作空间。一个服务实例用户可以被同时添加进入多个工作空间，并被授予这些工作空间内对象的权限。
-
-以上图中的对象为例，介绍工作空间的隔离和数据互通方式：
-
-当上图中的用户user\_a同时被加入了工作空间A(workspace\_a)和工作空间B(workspace\_b)，并被授予了A和B两个工作空间的计算集群使用、数据对象查询等所需的权限。那么user\_a在工作空间A内的任务脚本demo\_script\_ws\_a和工作空间B内的任务脚本demo\_script\_ws\_b中执行以下语句均可正常得到查询结果。
-
-```
-select * from table workspace_a.schema_a.table_a limit 10;
-```
-
-而用户user\_b仅被加入了工作空间B(workspace\_b)，并授予了工作空间B内的一系列权限，当执行任务脚本demo\_script\_ws\_b对workspace\_a.schema\_a.table\_a进行查询时，会提示user\_b并不具备该表的select权限。
-
-## 使用场景
-
-一个服务实例（instance）中可以创建多个工作空间，您可以根据自身业务需要选择使用单一工作空间或多个工作空间。单一工作空间有利于管理，更方便对数据资产和计算资源进行统一管理；多个工作空间有利于在多个团队或项目间实现天然的权限、数据和计算资源边界。
-
-## 使用单一工作空间
-
-当您处于以下使用场景时，推荐仅使用默认开通的工作空间作为单一工作空间来使用 Lakehouse：
-
-* **个人或小型团队**：团队人数较少，数据与计算规模也不庞大，希望在同一个环境内进行协作和管理。
-* **单一产品线或业务部门**：只需管理一个业务域的数据与数据处理流程，对数据与访问控制的精细拆分需求相对较低。
-
-服务实例开通后，系统默认会创建一个名为“quick\_start”的工作空间。您可以直接使用此工作空间进行任务开发等工作。
-
-在管控中心的“账户主页”中，点击开通的服务实例，可进入服务实例的首页。
-
-:-: ![](.topwrite/assets/image_1721463116737.png =745)
-
-在服务实例的首页，点击左侧功能菜单中的“开发”、“计算”、“运维监控”等任意功能，页面右上角会列出当前账号具备权限访问的工作空间，支持切换。使用单一工作空间时，默认处于服务实例内仅有的一个工作空间中。此时所有的任务脚本、调度作业都处于该工作空间内。
-
-:-: ![](.topwrite/assets/image_1721463152612.png =743)
-
-## 创建并使用多个工作空间
-
-当您处于以下使用场景时，推荐创建并使用多个工作空间：
-
-* **跨部门或多项目隔离**：当业务部门或项目之间需要数据和资源访问隔离时，可通过多个工作空间实现天然的权限边界。
-* **安全与合规要求高**：金融、医疗、政府机构等对数据安全、合规和可审计性要求很高的行业场景，需要通过强隔离的方式加强数据安全。
-* **不同的计费或预算中心**：如果多个部门或项目分别有独立的预算，则各自独立的工作空间便于进行财务结算和成本追踪。
-
-服务实例的实例管理员（instance\_admin）角色可以创建工作空间。操作方式如下：
-
-进入“管理-工作空间”菜单，在工作空间管理页面中点击“新建空间”，填写所需信息后进行创建。
-
-:-: ![](.topwrite/assets/image_1721463203358.png =794)
-
-^
-
-工作空间的名称一经创建，不允许变更。新的工作空间会默认创建一个名为“public”的 schema，以及 3 个不同类型的计算集群（通用型计算集群、分析型计算集群和同步型计算集群），便于快速在工作空间中开始操作。
-
-新建工作空间的用户会默认被授予这个工作空间的空间管理员（workspace\_admin）角色。
-
-使用多个工作空间时，可在“开发”、“计算”、“运维监控”等功能页面中，通过右上角的工作空间按钮，切换不同工作空间环境进行使用。
-
-:-: ![](.topwrite/assets/image_1736089880260.png =785)
-
-^
-
-一个服务实例用户如需使用某个工作空间中的数据和计算资源，需要被加入该工作空间并被授予相应的权限。这一操作需要具备该工作空间的空间管理员角色（workspace\_admin）用户来执行。更多操作说明请参考“访问控制”-“配置访问控制”中的[工作空间级管理](access-control-configration.md)的相关内容。

-# 数据分享
-
-## 1. 概述
-
-### 什么是数据分享（Data Share）
-
-数据分享是云器 Lakehouse 提供的 **无复制** 数据共享功能，可在同一服务区域内实现 **跨账户或跨服务实例** 的数据授权与使用。与传统的数据复制或导入方案不同，数据分享不需要在企业间手动搭建数据同步链路，而是通过“授权”方式直接提供对源数据的只读访问，且实时更新。
-
-### 应用场景
-
-* **实时共享场景**：A 企业将自身数据（例如交易日志、用户行为数据）实时共享给 B 企业，B 企业不需要做数据同步即可实时查询更新数据。
-* **多方协作分析**：多家合作方基于同一份实时数据进行分析、挖掘，减少重复存储和传输成本。
-* **数据提供商与数据消费者模式**：数据提供方希望将部分数据开放给合作伙伴，合作伙伴无需承担存储成本即可获得只读数据，用于自有的 BI 分析或产品集成。
-
-### 本文案例
-
-本文将以 **A 企业**（数据提供方）和 **B 企业**（数据接收方）为例，介绍以下操作：
-
-1. **A 企业创建 Data Share 并分享数据**：A 企业在自身数仓中拥有Brazil\_Commercial的电商数据，希望将脱敏后的数据纳入到 Data Share 中，指定分享给 B 企业。
-2. **B 企业接收并提取 Data Share 中的数据**：B 企业在自己的云器 Lakehouse 实例中，收到A企业的分享并创建对应的 schema 来提取共享数据。
-3. **B 企业使用提取的数据关联 BI 应用，制作报表**：B 企业基于 Data Share 提取出来的只读数据进行分析，在 BI 工具中制作报表。
-4. **A 企业写入数据，B 企业的报表实时获取数据变更**：由于 Data Share 无复制且实时，A 企业对数据所做的更新可以在 B 企业第一时间可见。
-
-***
-
-## 2. A 企业创建数据分享并指定企业B进行接收
-
-以下示例中，A 企业有物流情况表rpt\_brazil\_ec，其中包含所有销售方所有产品的物流状态。B企业是A企业其中的一个销售方（seller），A企业需要向B企业提供其销售产品的物流状态，以便B企业使用这些数据做BI看板，分析和跟踪物流状态。为此，A 企业将对 rpt\_brazil\_ec进行数据过滤，创建一个仅包含B企业数据的视图 `sub_rpt_brazil_ec_05e107217c7266362fd44b75b2cd4cc4`，并将该视图分享给企业B。
-
-### 2.1 创建视图
-
-因物流情况表rpt\_brazil\_ec中包含所有销售方的数据，出于数据安全考虑，不可将所有数据提供给B企业。所以需要先创建一个视图，仅包含B企业的数据，并仅分享这个视图。
-
-表rpt\_brazil\_ec中包含销售方ID字段：seller\_id，以这个字段作为过滤条件创建以下视图：
-
-```
---为share创建独立的schema，便于后续管理和维护
-CREATE SCHEMA seller_data_share;
-​
---创建视图，这里假设企业B的seller_id为05e107217c7266362fd44b75b2cd4cc4
-CREATE    VIEW seller_data_share.sub_rpt_brazil_ec_05e107217c7266362fd44b75b2cd4cc4 AS
-SELECT    *
-FROM      rpt_brazil_ec
-WHERE     seller_id = '05e107217c7266362fd44b75b2cd4cc4';
-```
-
-### 2.2 创建数据共享并分享给指定企业B
-
-#### Web 界面操作
-
-**1）创建数据分享**
-
-* 使用具备“实例管理员”（`instance_admin`）角色的账号登录云器 Lakehouse 控制台。
-* 左侧导航选择“数据” → “数据分享”，点击“+新增分享”。
-
-:-: ![](.topwrite/assets/image_1740388043727.png =742)
-
-* 在弹窗中填写分享名称（如 shipping\_detail），选择待分享数据所在的工作空间。
-* 注意，待分享数据需在同一个工作空间内。如果数据本身分布在多个工作空间，可以在一个工作空间内创建其他空间待分享数据的视图，以集中所有待分享数据到同一工作空间。
-
-:-: ![](.topwrite/assets/image_1740388342928.png =438)
-
-**2）添加要分享的数据对象**
-
-继续在新建分享的弹窗中，点击“添加”，选择要分享的对象。如下图，在ql\_ws空间下找到上文创建的schema：seller\_data\_share，勾选其中的视图：seller\_data\_share.sub\_rpt\_brazil\_ec\_05e107217c7266362fd44b75b2cd4cc4
-
-点击“完成”后，该视图即被纳入分享列表。
-
-:-: ![](.topwrite/assets/image_1740388392799.png =537)
-
-^
-
-**3）配置接收实例**
-
-在同一个弹窗中，点击“接收实例”下方的“添加”按钮，输入 B 企业的云器 Lakehouse “服务实例名称”（需要B企业提供，在其登陆服务实例后的首页右上方），并点击完成。
-
-:-: ![](.topwrite/assets/image_1740388438814.png =531)
-
-^
-
-**4）完成数据分享创建**
-
-完成上述所有内容填写后，点击“确定”按钮，即完成数据分享对象的创建，并指定分享给了企业B的Lakehouse服务实例。
-
-后续还可对该数据分享进行编辑，增减需要分享的数据对象，或增减接收此数据的Lakehouse服务实例（比如需要给B企业的其他服务实例）。
-
-**5）查看或管理分享对象**
-
-创建完成后，可以在“数据分享” → “我分享的”列表中看到刚创建的数据分享对象。
-
-:-: ![](.topwrite/assets/image_1740390203623.png =718)
-
-^
-
-#### SQL 操作
-
-若更偏好 SQL 操作，则请使用具备 “实例管理员”（`instance_admin`）角色的账号，在 A 企业的工作空间（如 `ql_ws`）下执行以下操作：
-
-**1) 创建 Share**
-
-```
-CREATE SHARE shipping_detail;
-```
-
-**2) 将视图纳入 Share**
-
-```
---注意，select赋予接收者查询数据的能力，read metadata赋予接收者可见这个view对象的能力，两个权限点均需要授予。
-GRANT SELECT, READ METADATA ON VIEW seller_data_share.sub_rpt_brazil_ec_05e107217c7266362fd44b75b2cd4cc4 TO SHARE shipping_detail;
-```
-
-**3) 配置分享目标实例**
-
-```
-ALTER SHARE shipping_detail ADD INSTANCE '<替换为B企业的instance_name>';
-```
-
-其中需要由 B 企业提供其Lakehouse服务实例的名称。此操作后，B 企业将立即获得share shipping\_detail的使用权，并可从其中提取view：seller\_data\_share.sub\_rpt\_brazil\_ec\_05e107217c7266362fd44b75b2cd4cc4
-
-的只读访问权限。
-
-> 完成以上步骤后，A 企业即已成功将过滤后的数据通过数据分享功能分享给 B 企业。
-
-##
-
-### 2.3 B 企业接收并提取 Data Share 中的数据
-
-在完成 A 企业分享后，B 企业需要在自己的云器 Lakehouse 实例中“接收并提取”分享数据，才能在查询中使用到该视图对象。
-
-#### Web 界面操作
-
-**查看分享给我的对象**
-
-登录 B 企业的云器 Lakehouse 控制台，使用具备“实例管理员”或“工作空间管理员”角色的账号。
-
-左侧导航选择“数据管理” → “数据分享”，切换到“分享给我”页签，即可看到 A 企业分享过来的 shipping\_detail。
-
-^
-
-**提取数据**
-
-在 shipping\_detail 卡片下方点击“提取”按钮。
-
-弹窗中选择“源 schema”（一个数据分享中可能包含多个schema，需要指定schema进行数据提取），以及想要将共享数据落到 B 企业服务实例下的哪个工作空间及对应 schema。
-
-注意，这里会根据填写的schema名称新建对应的schema，且该schema为只读，不可在此schema下创建其他table或view等数据对象。
-
-完成填写后，点击“确定”按钮，系统会在 B 企业的指定工作空间中新建只读 schema，并映射到 A 企业分享的对象。
-
-^
-
-**完成提取后**
-
-B 企业可以在“数据目录”或“开发”功能的“数据”页签中，看到对应的新 schema，并看到view：sub\_rpt\_brazil\_ec\_05e107217c7266362fd44b75b2cd4cc4。
-
-可像使用本地数据对象一样，对view中的数据进行查询操作。
-
-^
-
-### 2.4 SQL 操作
-
-如果使用 SQL提取share中的数据，在 B 企业的工作空间中执行以下命令：
-
-**查看分享对象**
-
-```SQL
-SHOW SHARES;
-```
-
-可查看到 `INBOUND` 类型的，名称为shipping\_detail 的数据分享，来自 A 企业的服务实例。
-
-**查看shipping\_detail中有哪些数据**
-
-```
-DESC SHARE shipping_detail;
-```
-
-^
-
-**创建本地 Schema**&#x20;
-
-```
-CREATE SCHEMA b_workspace_share_schema FROM SHARE A_instance_name.shipping_detail.share_demo;
-```
-
-其中 `A_instance_name`、`share_demo` 以及源 schema 名可通过 `SHOW SHARES;` 和 `DESC SHARE share_demo;` 查询到。
-
-`b_workspace_share_schema` 为在 B 企业工作空间中新建的只读 schema 名称，可自定义。
-
-^
-
-***
-
-## 4. B 企业使用提取的数据关联 BI 应用制作报表
-
-B 企业提取并成功创建了只读 schema 后，即可在任意兼容云器 Lakehouse 的 BI 工具或 SQL 工作台中，对 `orders_view` 进行查询或关联分析。例如：
-
-```
-SELECT 
-    order_id,
-    customer_id,
-    order_amount,
-    order_status
-FROM b_workspace_share_schema.orders_view
-WHERE order_status = 'COMPLETED';
-```
-
-* **关联外部数据**：可将 `orders_view` 与 B 企业内部自有数据表进行关联（`JOIN`）分析。
-* **数据建模**：可在 BI 工具中将 `orders_view` 作为数据源进行数据可视化与报表制作。
-
-此时，B 企业已经不需要关心数据是否实时同步——Data Share 保证了当 A 企业源数据更新时，B 企业查询到的就是最新的数据。
-
-***
-
-## 5. A 企业在 Data Share 中写入数据，B 企业报表实时查询变更
-
-当 A 企业往 `orders_view` 对应的底层表 `orders` 插入新数据，或者更新现有订单数据时，Data Share 会自动将变更后的数据实时暴露给 B 企业。B 企业无需额外操作，即可在 SQL 查询或 BI 报表中看到最新结果。
-
-示例：A 企业执行以下语句更新订单状态，B 企业在其已有的报表中就能立即看到状态更新后的记录。
-
-```
--- A 企业在 workspace_a 中执行
-UPDATE orders
-SET order_status = 'SHIPPED'
-WHERE order_id = 10001;
-```
-
-B 企业通过之前的 BI 报表或下列 SQL 查询，实时获取最新状态：
-
-```
--- B 企业执行
-SELECT 
-    order_id,
-    order_status
-FROM b_workspace_share_schema.orders_view
-WHERE order_id = 10001;
-```
-
-***
-
-## 总结
-
-通过以上 5 步操作，您可以在云器 Lakehouse 平台上实现类似 Snowflake Data Sharing 的实时数据共享。Data Share 最大的特点在于：
-
-* **无复制、低延迟**：无需在企业间重复存储或定期同步，数据变更可以实时传播给消费方。
-* **数据安全可控**：数据仅以“只读”形式分享，且随时可通过权限管控移除共享对象。
-* **易于扩展**：通过 View 可以灵活过滤数据列或行，实现精细化的分享控制。

-# 为团队快速搭建 Lakehouse 数据开发环境
-
-## 概述
-
-本文档旨在帮助您在最短时间内搭建一套可供团队共同使用的 Lakehouse 数据开发环境，环境中包括多个可登录并进行数据开发的用户身份，不同用户身份被授予不同的数据权限和角色，以保证必要的权限管控、资源配置和协作便利性。
-
-:-: ![](.topwrite/assets/lakehouse-data-sharing-new.svg =721)
-
-## 1. 准备工作
-
-1. **开通云器账号**
-
-   如果您还没有云器账号，可以前往 [云器官网](https://www.yunqi.tech/) 注册获取。开通注册方式可参考[开通使用](setup.md)。
-
-2. **创建Lakehouse服务实例**
-
-   您需要至少已创建一个Lakehouse服务实例。如还未开通服务实例，可参考：[开通使用](setup.md)中的“创建Lakehouse服务实例”说明进行操作。
-
-3. **拥有 Lakehouse服务实例的instance\_admin(实例管理员) 角色**
-
-   Lakehouse 的权限管理是基于角色（Role）的，创建Lakehouse服务实例的用户会默认具备该服务实例的instance\_admin（实例管理员）角色。
-
-## 2. 搭建完成后
-
-按照后续章节完成环境搭建后，您将得到以下环境：
-
-1. 一个Lakehouse服务实例下的独立工作空间；
-2. 多个可用的用户身份，并具备在工作空间下进行数据开发的权限；
-3. 一个SQL任务，并可提交为周期运行。
-
-***
-
-## 3. 操作步骤
-
-### 3.1 创建用户
-
-注册云器账户时，会默认创建该账户下的第一个用户，并具备账户下所有的操作权限。当团队中多人共同使用Lakehouse进行开发时，使用多个用户身份并区分权限，可以有效对数据和资源进行管理，增强安全性、降低操作冲突的风险，并能有效审计和追溯个人操作。
-
-为达到上述管理目的，需要为每个开发人员或每个集成服务创建独立的用户，以便为后续分配相应角色做准备。
-
-使用注册云器账户时的默认用户[登录](https://accounts.clickzetta.com/login)云器产品，进入管理中心页面，并切换至“用户管理”功能：
-
-:-: ![](.topwrite/assets/quickstart_team_p1.png =801)
-
-^
-
-点击右上角的“新建”按钮，选择“新建用户”，这里分别创建2个用户：developer 和 analyst，如下所示：
-
-:-: ![](.topwrite/assets/quickstart_team_p2.png =361)
-
-^
-
-:-: ![](.topwrite/assets/quickstart_team_p3.png =360)
-
-创建成功后，可以在用户管理的用户列表中看到这两个用户。
-
-### 3.2 创建工作空间
-
-在Lakehouse中，工作空间用于隔离计算资源和数据，形成相对独立的数据开发环境，避免资源冲突或误操作数据。开通Lakehouse服务实例后，系统会默认创建一个名为quickstart的工作空间（workspace）。这里为了完整介绍团队使用方式，我们创建另外一个工作空间：dev\_envirment：
-
-仍然使用注册账户时创建的用户登录，并在管理中心点击已开通的服务实例名称，进入服务实例首页。
-
-:-: ![](.topwrite/assets/quickstart_team_p4.png =797)
-
-^
-
-在服务实例首页中，依次点击左侧菜单中的“管理”-”工作空间“，进入工作空间管理页面。点击右上角的”+ 新建空间“按钮：
-
-:-: ![](.topwrite/assets/quickstart_team_p5.png =774)
-
-^
-
-在弹窗中输入工作空间的名称，点击“确定”，完成工作空间创建：
-
-:-: ![](.topwrite/assets/quickstart_team_p6.png =382)
-
-^
-
-:-: ![](.topwrite/assets/quickstart_team_p7.png =733)
-
-^
-
-### 3.4 创建schema和table
-
-在 Lakehouse 的工作空间中，schema 用于进一步归类数据表和视图。可根据团队规模和业务需求规划 schema 层级。以下先创建3个schema：STG、CORE和ADS。
-
-首先在新创建的dev\_envirment工作空间的右侧点击“开发”，进入开发页面，并执行以下SQL，创建schema：
-
-:-: ![](.topwrite/assets/quickstart_team_p8.png =730)
-
-^
-
-:-: ![](.topwrite/assets/quickstart_team_p9.png =736)
-
-在Schema STG中创建2张表，并插入部分样例数据：
-
-```SQL
-CREATE SCHEMA STG;   -- 数据源原始或暂存表存放
-CREATE SCHEMA CORE;  -- 核心事实表/维度表存放
-CREATE SCHEMA ADS;   -- 汇总或分析结果表存放
-
-
-----------------------------------------------------------
--- 1. 在STG层创建示例表: EMPLOYEES
-----------------------------------------------------------
-CREATE TABLE STG.EMPLOYEES (
-    EMP_ID          INT,
-    EMP_NAME        VARCHAR(50),
-    DEPARTMENT      VARCHAR(50),
-    JOIN_DATE       STRING
-);
-
--- 向表中插入一些示例数据
-INSERT INTO STG.EMPLOYEES (EMP_ID, EMP_NAME, DEPARTMENT, JOIN_DATE) VALUES
-    (101, 'Alice',    'Engineering', '2023-07-10'),
-    (102, 'Bob',      'Sales',       '2024-08-05'),
-    (103, 'Charlie',  'Finance',     '2024-09-01');
-
-----------------------------------------------------------
--- 2. 创建示例视图: EMPLOYEES_OVERVIEW
-----------------------------------------------------------
-CREATE VIEW ADS.EMPLOYEES_OVERVIEW AS
-SELECT 
-    EMP_ID,
-    EMP_NAME,
-    DEPARTMENT,
-    JOIN_DATE
-FROM EMPLOYEES;
-```
-
-### 3.5 将团队成员加入工作空间并授权
-
-上文中创建的两个用户：developer 和 analyst，默认并不具备任何数据操作和资源使用的权限。需要经由具备工作空间管理员角色（workspace\_admin）的用户授权后，才可以进行操作。
-
-假设我们希望这两个用户各自的权限范围是：
-
-**developer用户**，可以使用“开发”功能；可以在dev\_environment工作空间下对所有数据进行读写操作，并可以创建和删除table、view等对象；可以使用dev\_environment工作空间下所有的计算集群资源；可以提交并维护dev\_environment工作空间下的周期任务。
-
-**analyst用户**，可以使用“开发”功能；对schema ADS 下的所有表和视图具备只读权限，对表stg.employees具备只读权限；可以使用dev\_environmentt工作空间下所有的计算集群资源。
-
-为了达到以上效果，需要继续使用创建dev\_environment工作空间的用户，打开“开发”功能，新建SQL脚本，并执行以下授权语句：
-
-```SQL
-----------------------------------------------------------
--- 1. 为developer用户授权
-----------------------------------------------------------
---将用户developer加入工作空间，仅加入工作空间后，才可以授予该工作空间下元数据对象的权限
-CREATE USER developer;
-
---为用户developer授予workspace_dev角色,以具备以下权限“可以使用'开发'功能；可以在dev_environment工作空间下对所有数据进行读写操作，并可以创建和删除table、view等对象；可以使用dev_environment工作空间下所有的计算集群资源；”
-GRANT ROLE workspace_dev TO USER developer;
-
---为用户developer授予workspace_sre角色，已具备“可以提交并维护dev_environment工作空间下的周期任务”的权限
-GRANT ROLE workspace_sre TO USER developer;
-
-
-----------------------------------------------------------
--- 2. 为analyst用户授权
-----------------------------------------------------------
---将用户analyst加入工作空间，仅加入工作空间后，才可以授予该工作空间下元数据对象的权限
-CREATE USER analyst;
-
---为用户analyst授予workspace_analyst角色,以具备以下权限“可以使用'开发'功能；可以使用dev_environment工作空间下所有的计算集群资源；”
-GRANT ROLE workspace_analyst TO USER analyst;
-
---为用户analyst授予单独授予部分数据权限，以实现“对schema ADS 下的所有表和视图具备只读权限”
-GRANT SELECT, READ METADATA ON ALL TABLES IN SCHEMA ads TO USER analyst;
-GRANT SELECT, READ METADATA ON ALL VIEWS IN SCHEMA ads TO USER analyst;
-
---为用户analyst授予单独授予部分数据权限，以实现“对表stg.employees具备只读权限”
-GRANT SELECT, READ METADATA ON TABLE stg.employees TO USER analyst;
-
-```
-
-上述授权操作中，将用户加入工作空间和授予角色的操作也可以通过WEB页面操作完成。
-
-**web端加入工作空间操作**
-
-继续使用创建dev\_environment工作空间的用户，点击左侧菜单“管理”-“工作空间”，进入工作空间列表，找到dev\_environment工作空间，点击进入。在工作空间详情页面的“用户”页签右侧点击“+添加用户”按钮：
-
-:-: ![](.topwrite/assets/quickstart_team_p10.png =774)
-
-^
-
-在弹窗中找到用户 developer 并勾选（可以同时找到 analyst 用户，一起勾选。但是因为两个用户要授予的权限不同，此处分开操作，仅先添加 developer 用户）。
-
-:-: ![](.topwrite/assets/quickstart_team_p11.png =763)
-
-^
-
-此时下方有两个按钮，点击右边的“添加用户”，仅执行添加用户进入工作空间的操作，不做任何授权。点击左边的“添加用户并授予角色”，可以进一步选择要授予的角色。假设我们点击左边的“添加用户并授予角色”按钮：
-
-:-: ![](.topwrite/assets/quickstart_team_p12.png =772)
-
-^
-
-在可授予的角色中，我们选择“workspace\_dev"角色，勾选并点击”角色授予“。
-
-完成上述操作后，我们即完成了对用户developer的加入工作空间和授权操作。效果和上述SQL执行的授权等价。
-
-对用户analyst的授权操作，由于包含“单独授予部分数据权限”的操作，这部分操作推荐使用SQL的GRANT语句执行授权，更为便利。
-
-### 3.6 检查授权结果
-
-Lakehouse支持使用SHOW GRANTS语句查询用户已授予的权限。
-
-在“开发”功能中执行以下语句：
-
-```SQL
-SHOW GRANTS TO USER developer;
-```
-
-返回结果如下：
-
-:-: ![](.topwrite/assets/quickstart_team_p13.png =738)
-
-^
-
-### 3.7 团队成员登录系统
-
-完成上述操作后，developer和analyst两个用户均可以登录Lakehouse，并具备了相应的权限可以进行数据开发或查询。下面使用developer用户登录系统。
-
-回到云器的登录页面<https://accounts.clickzetta.com/login>，依次输入账户名称、用户名和密码。其中账户名称在账号注册成功后提供，并可在该账户任意用户登录后的 URL 中获取。
-
-:-: ![](.topwrite/assets/quickstart_team_p15.png =746)
-
-现在使用developer用户，在<账户名称>.accounts.clickzetta.com/login URL登录，并点击“Lakehouse”产品下“进入”服务实例按钮，进入Lakehouse服务实例中。
-
-:-: ![](.topwrite/assets/quickstart_team_p16.png =740)
-
-### 3.8 团队成员编写开发任务
-
-developer用户登录后，在左侧菜单中进入“开发”页面。因当前developer用户只加入了dev\_envirment这一个工作空间，所以无需切换工作空间。如果加入多个工作空间，可以在右上角切换所需进行开发的工作空间。
-
-:-: ![](.topwrite/assets/quickstart_team_p17.png =739)
-
-^
-
-点击“开发”功能的“+”新建SQL脚本，写一条查询语句查询 stg.employees 表中的数据。
-
-:-: ![](.topwrite/assets/quickstart_team_p18.png =717)
-
-^
-
-```SQL
-select * from stg.employees limit 10;
-```
-
-:-: ![](.topwrite/assets/quickstart_team_p19.png =740)
-
-^
-
-依次点击“保存”按钮保存任务代码，点击“调度”按钮打开调度配置弹窗。
-
-:-: ![](.topwrite/assets/quickstart_team_p20.png =572)
-
-^
-
-在弹窗中配置调度任务的周期、重跑方式等信息，然后点击“确定”按钮，即完成该任务的调度配置操作。
-
-:-: ![](.topwrite/assets/quickstart_team_p21.png =730)
-
-^
-
-成功配置调度后，“提交”按钮变为可点击状态。点击“提交”后，该任务即提交为周期调度运行。
-
-:-: ![](.topwrite/assets/quickstart_team_p22.png =695)
-
-^
-
-以上即完成了从创建用户、授权到使用新用户开发SQL任务并提交周期调度运行的过程。

-# 快速分析本地的CSV 文件
-
-### **目标**：
-
-通过本篇文档，能够利用 Lakehouse 快速分析本地的 CSV 文件
-
-### **分析 CSV 格式文件**：
-
-#### **数据准备**：
-
-本文以巴西电商公共数据集为例，在客户端的本地路径 /User/Downloads/brazil-ecommerce 有如下 csv 文件：
-
-```
--------------/User/Downloads/brazil-ecommerce ------------------ 
-olist_customers_dataset.csv.gz 
-olist_geolocation_dataset.csv.gz
-olist_order_items_dataset.csv.gz 
-olist_order_payments_dataset.csv.gz 
-olist_order_reviews_dataset.csv.gz 
-olist_orders_dataset.csv.gz
-olist_products_dataset.csv.gz 
-olist_sellers_dataset.csv.gz 
-product_category_name_translation.csv.gz
-```
-
-利用 Lakehouse JDBC 客户端 SQLLine（或 DBeaver / Datagrip 等）将数据上传至 Lakehouse User volume 空间（限制：单文件需小于5G）：
-
-(USER VOLUME 是当前用户在当前的工作空间下，默认开通的文件存储空间，无需提前创建）
-
-```
---在 SQLline 或者任意 Lakehouse JDBC 客户端中执行，上传单一文件：olist_customers_dataset.csv.gz
-
-PUT '/User/Downloads/brazil-ecommerce/olist_customers_dataset.csv.gz' TO USER VOLUME SUBDIRECTORY 'bz_olist_data';
-```
-
-在客户端工具，或者 Studio SQL 任务节点中，执行如下命令展示已经上传到 USER VOLUME 中的文件：
-
-```
-show user volume directory like '%olist%';
-```
-
-#### **通过 Lakehouse SQL 快速分析数据**
-
-如：统计每个州（state）有多少用户，并按用户数降序排序
-
-```
-SELECT count(1) as customer_number_by_state,
-       customer_state,
-FROM USER VOLUME (
-    customer_id STRING,
-    customer_unique_id STRING,
-    customer_zip_code_prefix INT,
-    customer_city STRING,
-    customer_state STRING
- ) using csv Options
- (
-     'sep' = ',',
-     'compression'='gzip',  -- 目前支持 zstd/gzip/zlib 压缩格式。无压缩直接去掉此参数
-     'header'='true'
- )
- FILES ('bz_olist_data/olist_customers_dataset.csv.gz')
-group by customer_state
-order by customer_number_by_state desc;
-```
-
-其中，Options 中的选项：
-
-* sep：列分隔符，默认为 ” , “。最多支持长度为 1 的字符，例如：`'sep'=','`
-* compression：配置文件压缩格式。支持的压缩格式有：gzip/zstd/zlib。例如：`'compression'='gzip'`
-* header：是否解析表头，默认为 false。布尔类型，例如：`'header'='true'`
-
-除此之外，还支持以下参数：
-
-* timeZone：配置时区，没有默认值。用于指定文件中时间格式的时区。例如：`'timeZone' = 'Asia/Shanghai'`
-* escape：用于转义已加引号的值中的引号，默认值为”\“，例如：`'escape'='\'`
-* lineSep：行分隔符，默认值为"\n"。最多支持长度为 2 的字符，例如：`'lineSep'='$'`
-* quote：设置用于转义引号值的单个字符。默认值为双引号“"“，例如：`'quote'='"'`
-
-#### **将文件生成 lakehouse 内表**
-
-```
-CREATE TABLE OLIST_CUSTOMER_TBL
-AS
-SELECT * FROM USER VOLUME (
-    customer_id STRING,
-    customer_unique_id STRING,
-    customer_zip_code_prefix INT,
-    customer_city STRING,
-    customer_state STRING
- ) using csv Options
- (
-     'sep' = ',',
-     'compression'='gzip',
-     'header'='true'
- )
- FILES ('bz_olist_data/olist_customers_dataset.csv.gz');

-# 实时同步任务
-
-云器Lakehouse工作空间的“开发”模块集成了数据同步任务的定义和调度能力。借助数据开发模块的数据同步任务编辑器，可以快速创建数据同步任务。以下对实时同步任务的创建和使用进行说明。
-
-## 新建数据同步任务
-
-您可分别通过工作区和开发入口新建同步任务。
-
-* 由工作区新建
-  通过控制台“工作区”入口，在右侧“新建”按钮下选择新建离线同步或实时同步任务。
-
-  ![](.topwrite/assets/image_1690124841165.png =640)
-
-* 由开发入口新建
-  您可进入“开发”页面，在任务区域选择在指定目录下新建同步任务。
-
-  ![](.topwrite/assets/image_1690125196037.png =320)
-
-## 实时同步任务开发
-
-本节以Kafka数据源实时同步至Lakehouse为例进行说明。
-
-* 新建实时数据同步任务并配置源及目标信息
-  选择Kafka数据源，通过数据对象选择Topic，并指定位点及消息格式。目标端选择Lakehouse数据源及对应的数据对象。
-  ![](.topwrite/assets/image_1690128155312.png =708)
-
-  默认使用Kafka Topic内置字段进行数据字段映射。如果Topic内的消息格式为JSON，您还可以通过新增计算列的方式，使用JSONPath规则解析value字段中的内容，例如 `$.id`、`$.data.code`。
-
-
-* 部署至生产
-  实时同步任务不支持开发状态下的测试运行，也无需配置调度策略。您可通过“提交”按钮发布任务。
-  ![](.topwrite/assets/image_1690128987444.png =382)
-  提交后，可在运维中心对实时同步任务进行启停、运维操作及监控。

-# 低延迟实时湖仓数据集成和高性能实时分析
-
-本文档会介绍基于云器Lakehouse构建高稳定低延迟的实时湖仓数据集成方案和基于同一份湖仓数据的高性能实时分析两部分内容。
-
-## 概述
-
-随着企业业务的扩展，实时数据分析变得至关重要，它不仅是业务决策的支撑点，也是推动企业发展的必备条件。为了实现数据的实时分析，企业通常面临两种技术方案选择：
-
-* 直接利用业务数据库进行BI分析：这种方法操作简便，能够快速实施。然而，它在处理大规模数据和复杂查询时会遇到性能瓶颈，特别是在需要执行多表连接等复杂操作时，查询响应时间会显著延长，无法满足实时分析的需求。此外，出于对稳定性和安全性的考虑，业务数据库通常不允许直接用于数据分析，这限制了数据分析团队的操作空间。
-* 基于数据仓库的BI分析方案：该方案通过将数据从业务数据库同步到数据仓库，利用数据仓库的高性能处理能力来支持BI分析。这种方法有效解决了性能问题，但最大的挑战在于数据的实时性。传统的数据同步通常是T+1或H+1的批处理模式，无法满足业务对数据实时性的需求，往往还需要部署额外的OLAP引擎，这进一步增加了成本。
-
-云器Lakehouse提供了一种高稳定性、低延迟的实时湖仓数据集成解决方案，它能够实现从多种源端数据源（如MySQL、PostgreSQL、SQL Server等）的实时数据同步，并直接支持BI报表的实时查询。这种方案通过在数仓中维护同一份数据，既支持数据的实时写入，也支持BI报表的实时查询，消除了传统方案中需要额外部署OLAP引擎的需求。这样的设计简化了数据架构，降低了成本，同时确保了数据的实时性和查询效率，为企业提供了一种既经济又高效的实时数据分析解决方案。
-
-##
-
-## 实时湖仓数据集成
-
-此部分会展开介绍产品化的实时湖仓集成方案，如何便捷地将海量库表数据同步进入到Lakehouse湖仓。
-
-### 场景和数据描述
-
-本演示实践中，在源端MySQL数据库准备了四张各有 100 万行数据的表，计划将这 400 万行数据同步到目标云器Lakehouse的表中，然后直接使用 BI 报表进行查询分析。
-
-:-: ![](.topwrite/assets/image_1734675535069.png =570)
-
-^
-
-本演示以常见的 SaaS 服务模式为例，在多租模式下，数据库采取分库分表的结构，数据存在不同的分表；某些租户的信息会存在同一张分表内，且不同分表中包含特定租户的定制扩展字段，即源端是基本相同的四张分表，但部分表的字段存在细微差异，如下图所示，yellow\_taxi\_02 表，相比yellow\_taxi\_00表，多出了一个扩展字段 ext\_columm\_2 。
-
-:-: ![](.topwrite/assets/image_1734675556308.png =500)
-
-###
-
-### 前置准备：数据源配置
-
-导航到管理 -> 数据源，单击”新建数据源“并选择MySQL，即可创建本案例中所需的数据源。填写必须的配置信息，尤其请注意选择正确的数据库所在时区，实时同步对时区敏感，配置错误会使得同步失败。
-
-![](.topwrite/assets/image_1735208242938.png)
-
-源端数据库的权限等高阶配置，可以参考[此文档](realtime_sync.md)。
-
-### 实时同步任务的配置
-
-首先在任务开发里点击新建”多表实时同步任务“，选择正确的源端数据源类型，比如 MySQL。
-![](.topwrite/assets/image_1734939965441.png =630)
-
-实时同步任务提供两类数据同步模式：
-
-* 第一类：多表镜像同步，把源端的数据表，原原本本地镜像同步到目标端。
-* 第二类：多表合并同步，支持把源端多张表合并写入到目标端同一张表中，这也是本实践中用到的场景。源端数据量大、有分库分表的场景下，同步过程中把多张表合并写入到同一张表，在后续查询中就不再需要再进行多表JOIN、可以为查询提速。
-
-选择好同步模式之后，选择存储了源端连接串信息的数据源，如下图所示：
-
-![](.topwrite/assets/image_1734940034365.png)
-
-^
-
-接下来配置需要同步的数据对象。产品内提供了丰富的过滤规则来筛选源端表，比如命名的精确匹配、正则匹配等，可以按需使用。在源端表字段存在不一致的情况下，系统会自动检测进行识别、提示开启异构表合并同步功能。异构表合并同步功能作用是在目标端的表中，取源端表字段的并集进行建表，确保源端所有的数据能被同步写入到目标端。
-
-![](.topwrite/assets/image_1734949182748.png)
-
-配置完成后可以对具体的表的字段进行预览检查，确保扩展字段也被添加进来，保证数据一致。
-
-![](.topwrite/assets/image_1734952733442.png)
-
-如果使用镜像同步模式来代替多表合并模式，会把源端表的结构完整映射到目标表上，但还需要再进行 ETL 的处理加工、产出一张新的合并后的表供BI查询。增加表，也附带增加了一个处理链路，提升复杂度的同时会使得端到端的整个链路更长，数据新鲜度和时效性会大打折扣，成本也会提升。
-
-上文提到源端数据是采用分库分表的方式存储数据，但常常会遇到一种更复杂的情况：源端主键字段相同的取值的记录，在不同分表中的数据会出现重复。本示例中的数据也模拟设计了类似情况，在源端两张表同样的主键 ID 取值，在不同的表里分别会有一条记录，这会给同步过程带来了挑战：在合并写入到目标端时，如果是只按 ID 作为主键，这两条记录就会被尝试写入到一条记录中，会产生数据冲突的情况，两条源端的记录依据先后顺序被处理，后到的源端表中的数据被把先到的源端表中的数据给覆盖掉。面对这种情况，Lakehouse 实时同步方案中，提供了扩展字段的能力，来保证数据准确性。通过标识源端数据来源，比如将 server、databasename、 tablename 等字段设置为联合主键后，这两条数据在目标端会被当成两条记录来对待。通过这种方式，保证在即使源端出现分表中主键数据有重复的复杂情况下，源端数据也能被准确地同步到目标端。
-
-![](.topwrite/assets/image_1735208417539.png)
-
-完成上述配置后，下一步在“目标配置”里设定目标数据源类型、数据源名称等配置项。
-
-![](.topwrite/assets/image_1735205909270.png)
-
-接下来可以在映射关系中预览同步的字段配置，可以看到扩展字段包含在内，扩展字段/联合主键也在这里有所体现。
-
-![](.topwrite/assets/image_1735205869904.png)
-
-云器Lakehouse实时同步中，也提供了丰富同步规则策略，用来动态适配源端数据库的变更（Schema Evelution），比如源端表删除、新增字段等情况下的应对策略，以及需要处理的源端变更消息类型等。
-
-![](.topwrite/assets/image_1735205828392.png)
-
-到这里，整个实时同步任务就已经配置完成，只需要简单四步：**选择数据源、圈定源端同步对象、选定目标端，设定同步策略**。
-
-### 提交并启动数据实时同步
-
-云器Lakehouse提供了开发环境和生产环境两种模式，要将该任务在生产环境运行起来，需要先将其发布提交，然后在运维中心启动该任务。
-
-* 提交多表实时同步任务
-  ![](.topwrite/assets/image_1735206359814.png)
-
-* 运维多表实时同步任务
-  ![](.topwrite/assets/image_1735206291470.png)
-
-* 启动多表实时同步任务：启动时，可以根据实际需求，选择是否进行全量数据同步。首次同步的数据，通常建议选择做一次全量数据同步，然后再进行增量数据同步。
-  ![](.topwrite/assets/image_1735206439758.png)
-  ![](.topwrite/assets/image_1735206478684.png)
-
-任务启动后，在运维界面中，可以看到任务会进入全量同步阶段，数据已经写入 200 万行，速率在 25, 000+ 行/秒。
-
-![](.topwrite/assets/image_1734677235371.png)
-
-特别地，多表实时同步任务仅需要在第一次启动时对源端做一次全量同步，全量同步完成后，无需手动更改，任务会自动转入增量同步环节，保持数据的无缝衔接。
-
-### 验证数据变更的同步效果
-
-在实际应用中，经常会出现因为业务需要使得源端数据库的表和结构出现变化的情况，如源端表增加了字段，删除了字段、或者字段的类型变化了。对于这类情况，Lakehouse的实时同步也提供了对应的解决办法。
-
-云器Lakehouse产品支持直接操纵源端数据库，通过 SQL 来对源端数据库进行修改、查询等操作，首先我们对源端数据进行变更，先在源端添加一些新的字段：ext\_column\_0 & ext\_column\_1，并在源端表里删掉一个字段，同时更改一个字段类型从 int 改为 bigint 。
-
-![](.topwrite/assets/image_1734677264978.png)
-
-![](.topwrite/assets/image_1734677273784.png)
-
-![](.topwrite/assets/image_1734677283775.png)
-
-接下来可以在监控页面中看到，源端的数据变更已经被同步过来进行消费，基于在同步任务中配置的Schema Evelution规则，自动更新，无需手动操作进行其它额外配置、或者重启任务，这样能确保整个同步链路平滑运行。
-
-![](.topwrite/assets/image_1734677295827.png)
-
-同步完成后，也可以在任务运维界面中检查源端的变更是否被成功同步到目标端，可以看到，新增的字段 ext\_column\_0 & ext\_column\_1已经被扩展进目标端，更改的 bigint 字段也完成变更。

-
-### 实时同步任务的稳定性和指标监控
-
-实时同步和分析链路搭建完成后，最关心的问题之一就是整个链路的稳定性。我们的产品中，为每个多表同步任务提供了完善的监控信息展示，比如同步状态、同步延迟等。面向同步链路里可能会发生的异常情况，比如单条数据写入时发生异常导致任务失败，也提供了任务的自动 Failover 能力，任务失败以后会被自动拉起，减少人为运维处理的投入。
-
-![](.topwrite/assets/image_1734677408156.png)
-
-云器Lakehouse提供了监控告警产品模块，内置了丰富的状态和指标监控能力，支持自定义配置监控规则，来全面监控整个任务运行的状态，包括任务实例运行失败、单表存量数据同步异常、实时同步任务端到端延迟、作业 failover 、源端数据读取的点位延迟等等，一系列的监控事项，都可以通过配置对应的规则给监控起来。
-
-![](.topwrite/assets/image_1734677421992.png)
-
-本次实践演示中，配置了一些监控规则，可以看到下图告警通知，会监控端到端同步的延迟是否超过了 10 秒，在数量特别大时，延迟上去，会被监控捕获到，并通过告警通知提醒负责人感知并及时处理。
-

-
-### 实时同步任务的运维处置
-
-在实际生产过程中，经常会遇到各种各样的复杂问题，为此云器实时同步方案中也提供了多种配套运维处置功能来进行支持。例如在实时同步运行中，源端数据发生了变化，某个表中的数据出现了问题，针对这种情况，我们提供补数同步功能，支持对特定表重新进行全量同步。在业务突发高峰，源端变更流量非常大时，多个表的变更数据的实时同步会相互影响。这两种情况下，都可以通过全量补数同步的功能去加速数据同步过程。以下图为例，对源端表 yellow\_taxi\_00 表重新进行补数全量同步，其增量实时同步会被暂停，后台会通过全量的方式把源端数据重新同步。补数修订的全量同步完成后，增量同步会自动启动，无需再手动操作。
-
-![](.topwrite/assets/image_1734677453391.png)
-
-此外，云器Lakehouse还为日常运维提供优先执行功能，当在有多张表需要同步，而资源相对有限的条件下，可选择业务上更重要的表优先分配资源，在任务队列里面优先执行该表的数据同步，可以在任务整体出现消费堆积、端到端延迟变大的情况下，也能保证业务关键数据的新鲜度。

-## 高性能实时分析
-
-在传统离线数仓架构中，数据经过ETL处理后直接对接BI引擎进行查询，往往响应速度较慢。因此，企业通常会引入如Clickhouse等实时分析引擎来提升查询性能。云器科技的解决方案通过简化这一流程，实现了源端数据的实时写入与目标表的即时查询分析，无需额外的查询加速引擎。
-
-在本次演示中，我们利用Metabase BI工具构建的报表展示了源端MySQL数据行数统计与云器Lakehouse内数据行数的对比，并进行了复杂查询分析，如根据不同乘客数量统计费用的平均值。这一过程中，数据的实时同步写入与查询分析均在同一张表上完成，云器方案在简化架构和提升效率方面优势明显。
-
-![](.topwrite/assets/image_1734677365384.png)
-
-通过产品中提供的“作业历史”产品模块，可以看到提交到Lakehouse引擎的所有 SQL 明细。从下图中可以看到，实时同步写入的是 yellow\_taxi\_demo 表，在Metabase BI 看板里实时查询的也是该表。而且在演示的这个相对复杂的查询条件下，进行了400万行数据的全表扫描，能在 11 毫秒就返回查询结果。云器Lakehouse的方案不需要新增额外的加速引擎来进行查询加速，省去了再同步复制一份数据，所以能够极大地节约整体成本。
-
-![](.topwrite/assets/image_1734677380258.png)
-
-我们接下来看下高并发下的查询响应情况。云器Lakehouse 采用存算分离架构，在查询计算层面，通过不同集群类型来支撑不同的查询负载：
-
-* 通用型集群，面向批处理进行了针对性的优化。
-* 分析型集群，对于在线的实时分查询非常友好。
-
-云器也提供优秀的资源弹性能力，可以设定不同集群规格和弹性伸缩方式，可以配置查询的并发数以及实例的副本个数来实现动态伸缩。比如源端有 8 个并发时，只需要 1 个查询实例，通过弹性设置为 2 个副本，当并发数超过 8 个时，系统会自动拉起扩容出第 2 个副本来承接超过 8 个以上的并发流量，整个过程完全不需要人为干预。
-
-此外，云器Lakehouse还提供自动启停的功能，整个产品的资源收费模型上，在SaaS模式下采取按量付费的模式，比如对于 BI 报表，在夜间没有使用、没有流量时，集群会被自动停止，就会产生费用，能避免资源的空置浪费、节约成本费用。
-
-![](.topwrite/assets/image_1734677394361.png)
-
-## 总结
-
-云器Lakehouse基于一站式产品能力，提供了面向实时同步和实时分析场景的解决方案，应对源端数据库的复杂情况。产品支持对接MySQL、 PostgresSQL、SQLServer 等各种数据源，满足源端数据库存在异构情况下的同步要求，提供相对完善的高性能同步能力，和完善的配套运维监控能力保障数据的稳定生产。在成本方面，云器相比头部云厂商的传统同步方案，能够做到 50% 以上的整体成本节约。性能方面，具备更低的端到端的同步延迟，通常情况下可以做到 20 秒之内；以及更快的分析查询响应的速度，比如在较为复杂的查询SQL，也能够做到 10 毫秒的查询响应速度。基于云器Lakehouse的产品能力，可以为企业提供更好的数据新鲜度，让业务决策快人一步，在竞争中处于领先位置。

-# 全增量一体同步功能
-
-全增量一体同步功能是一项强大的数据同步工具，它能够将数据库中的数据完整地同步到Lakehouse中。该功能包括历史数据的全量同步和实时变更数据的增量同步。请注意，此功能目前处于 Beta 版本，部分已知局限将在后续版本中得到改进和优化。
-
-## 任务创建流程
-
-### 操作入口
-
-在任务开发界面，点击新建操作按钮，从下拉菜单中选择“全增量一体同步”任务类型。
-
-![新建全增量一体同步任务](.topwrite/assets/image_1710210458365.png)
-
-### 配置来源数据类型
-
-在创建任务时，首先需要选择一种需要同步的来源数据类型。目前支持的来源数据源类型及对应的增量读取模式和数据库版本如下：
-
-| **类型**     | **增量读取模式** | **数据库版本** |
-| ---------- | ---------- | --------- |
-| MySQL      | Binlog     | 5.x、8.x   |
-| PostgreSQL | WAL 日志     | 14 及以上     |
-
-### 选择同步类型
-
-全增量一体同步任务支持两种同步类型，请根据实际需求进行选择：
-
-1. 实时同步-多表镜像：适用于将源端数据完整地镜像同步到目标端的场景。
-2. 实时同步-多表合并：适用于将分库分表的数据合并后写入同一张目标表的场景。
-
-#### 多表镜像
-
-##### 来源配置
-* 选择数据源：选择一个已有的数据源。如果没有可用的数据源，请参考[数据源配置](config-datasource.md)文档新建一个数据源。
-* 配置读取模式：根据所选数据源类型，选择合适的读取模式。例如，MySQL数据源当前只支持BINLOG模式，而PostgreSQL数据源只支持WALs模式。
-* 选择同步对象：选择需要同步的数据库和表。可以通过批量配置功能，上传配置文件来快速选择多个同步对象。请注意，配置文件中的注释说明需要删除。
-* 配置槽位（slot）
-  * 仅PostgreSQL需要配置，槽位（slot）指PostgreSQL 的 replication slot，详见 [说明文档](https://www.postgresql.org/docs/9.4/catalog-pg-replication-slots.html)。
-  * 每个数据库都需要配置一个槽位。目前支持decoderbufs和pgoutput两种插件类型。
-  * 可以选择已存在的槽位进行使用；或者在页面页面来操作新建，在新建窗口的下方区域的创建语句，可按需修改。点击确定后进行创建。在数据源中配置的用户名必须具备创建slot的权限，否则会创建失败，详见下文的权限说明。
-  * 特别注意，不同任务不要复用同一个槽位。任务启动时，如果槽位被其他正在运行的任务占用，会启动失败。如果其他任务处于停止状态，因槽位中的数据会被共享消费，位点是共享的，新任务消费的增量数据，同步到目标端的表数据可能会不全。
-
-##### **目标配置**
-* 目标数据源：默认选择当前工作空间对应的Lakehouse数据源。
-* 命名空间规则：目前仅支持选择特定的命名空间。未来版本将支持按照源端进行镜像命名或自定义命名规则。
-* 目标表命名规则：目前仅支持镜像来源表名。后续版本将支持添加前缀或自定义命名规则。
-* 计算集群：选择工作空间下可用的计算集群。建议使用AP类型的集群。
-
-##### 预览配置
-在完成源端和目标端配置后，可以预览同步表和字段的映射关系。如有需要修改，可以返回上一步进行调整。
-
-##### 同步规则
-在同步规则中，可以配置Schema Evolution等规则，定义源端表和字段变化后的处理行为。
-
-#### 多表合并
-
-##### **来源配置**
-
-* 选择数据源
-  * 同上，多表镜像同步类似
-* 配置读取模式
-  * 同上，多表镜像同步类似
-* 选择同步对象
-  多表合并同步，会使用“虚拟表”作为中间的过渡承接，需要在配置时指定使用什么虚拟表来承接哪些对象的数据。支持两种方式进行配置
-  * 方式一：基于规则配置，通过正则匹配进行筛选，比如选出以 abc 开头的所有表，在正则表达式中填写 ^abc 即可
-  * 方式二：基于文件批量配置，按照模板中格式要求填写配置文件、上传后，页面会按照文件中给定的内容来选中需要同步的对象，选中后可以按需再进行微调。请注意删除模板文件中的注释说明
-
-##### **目标配置**
-* 同上，和多表镜像同步类似
-
-##### **预览配置**
-* 同上，和多表镜像同步类似
-
-##### **同步规则**
-* 同上，和多表镜像类似
-
-### 配置高级参数
-在任务常规配置完成后，点击“配置”按钮完成高级参数的设置。
-* 集群：指定用于运行同步任务的集群。建议使用AP类型的集群。
-* 更新频率：设定数据写入的频次间隔。
-
-### 提交任务
-点击提交按钮，将任务提交到生产环境执行。请注意，任务提交后默认不启动，需要手动启动。
-
-## 任务运维
-
-### 启动任务
-
-在任务详情页，可以操作启动任务。以下是三种启动方式：
-1. 无状态启动（仅适用于任务首次启动）：完整同步所有数据，先进行全量同步，再启动增量同步。
-2. 从上次保存状态恢复（适用于停止后的任务再次启动）：从停止位置断点续传。
-3. 自定义起始位置：从给定的位点进行同步，可用于数据回刷。对任务中配置的所有表统一生效。
-
-* MySQL：选择指定文件启动或者指定时间启动。在页面监控区域可以获取到上次文件位置。
-* PostgreSQL：指定 LSN 取值，在下文的实例监控中可以查看到最新的 LSN 取值。
-
-### 实例监控
-
-任务启动后，会经历初始化、全量同步、增量同步三个阶段。在实例监控区域，可以查看这三个阶段的运行状态。
-![实例监控](.topwrite/assets/image_1705386710920.png)
-
-### 指标监控
-
-在指标监控区域，可以查看全量同步和增量同步的关键监控指标。
-![指标监控](.topwrite/assets/image_1705386727702.png)
-
-| **指标名称**   | **口径说明**                                               |
-| ---------- | ------------------------------------------------------ |
-| 读取数据       | 数据同步任务在统计周期内从数据源读取的记录数。                                |
-| 写入数据       | 数据同步任务在统计周期内向目标数据源写入的记录数。                              |
-| 平均读取速率     | 数据同步任务在统计周期内平均读取速率。（周期内总读取记录 / 周期时间）                     |
-| 平均写入速率     | 数据同步任务在统计周期内平均写入速率。（周期内总写入记录 / 周期时间）                     |
-| Failover 次数 | 数据同步任务在统计周期内运行发生 Failover 次数。Failover 次数代表数据同步服务自身运行的稳定性。 |
-
-### 同步对象
-
-在同步对象区域，可以查看单表的同步终态和进行对应的运维操作。
-![](.topwrite/assets/image_1710214491047.png)
-
-| **指标** | **口径说明**                                    |
-| ------ | ------------------------------------------- |
-| 最新读取位置 | 同步任务实时读取来源对象数据并写入目标表，以目标表最新一条记录的写入时间作为读取位置。 |

-| 暂停     | 对于正在同步的表可操作，暂停该表的同步，保存同步位点。                  |
-| 恢复     | 从上次暂停的同步位点开始继续同步。                            |
-| 重新同步   | 对该表重新进行全量和增量同步。                              |
-| 查看异常   | 点击后可以查看表的增量同步任务的异常信息，比如 Schema Evolution 的异常等。 |
-
-### 停止任务
-
-停止任务会停止任务中正在进行的全量同步和增量同步。停止时会自动保存增量同步的位点状态。
-
-* 如果停止时表处在全量同步阶段，重启后，未完全全量同步的表，会重新进行一次全新的全量同步。
-* 如果停止时表处在增量同步阶段，重启后，默认会从同步停止的位点继续同步。
-
-### 下线任务
-
-下线任务属于高危操作，任务下线后，不会保存当前同步的位点。如果再次上线并启动任务，会重新开始同步数据。
-
-* 下线不会清理已经同步到目标端的数据，但会清理中间过程的缓存数据和位点信息。
-* 重新同步不会重新建表，全量数据同步会对于老的表进行覆盖写入，增量同步会对目标表做merge into的更新。
-
-## 权限说明
-
-同步不同类型数据源的变更事件时，需要在相应数据源服务端配置好适当的权限才能保证数据的正常同步。尽管直接分配管理员或超级用户的权限足以保证任务正常运行，但通常希望最小化需要分配给同步数据用户的权限。各操作步骤需要的具体权限配置说明如下。
-

-## 已知局限
-
-* 当前方案需要设定数据刷新频次，最少支持设置为 1 分钟。即端到端数据新鲜度延迟至少会在 1 分钟以上，尚未做到秒级延迟（会在后续版本提供）。
-* Schema Evolution，暂不支持变更字段类型、不支持自动新增表。
-* 多表实时同步任务中，源端不同库表中若存在主键相同的数据，同步结果会出现异常。
-* MySQL同步，尚不支持的字段类型：
-
-| 字段类型 | 同步后行为 |
-| ---- | ----- |
-| year | 取值不对应 |
-
-* PostgreSQL同步，尚不支持的字段类型：
-

-# 正则表达式支持的函数列表
-| 函数 | 说明 |
-| -------------------- | ------------------------------------------------------- |
-| RLIKE                | 用于检查一个字符串是否符合指定的正则表达式模式。                                |
-| REGEXP_EXTRACT       | 利用指定的正则表达式（regexp）从输入字符串（str）中提取匹配的文本。                  |
-| REGEXP_EXTRACT_ALL   | 用于从字符串中提取与正则表达式匹配的所有子串。                                 |
-| REGEXP_REPLACE       | 用于在字符串 str 中查找所有匹配正则表达式 regexp 的子字符串，并将它们替换为指定的字符串 rep。 |
-
-# 使用说明
-
-Lakehouse 使用的正则表达式引擎是 [re2](https://github.com/google/re2)。
-
-* **POSIX字符组**：允许使用如`[[:alnum:]]`这样的字符组。
-* **反斜杠序列**：包括`\d`（数字）、`\D`（非数字）、`\s`（空白字符）、`\S`（非空白字符）、`\w`（单词字符）、`\W`（非单词字符）、`\b`（单词边界）和`\B`（非单词边界）。
-* **POSIX通配符**：如`.`（匹配任意单个字符）和`*`（匹配前一个元素的零次或多次出现）。
-* **Unicode支持**：所有正则表达式函数均支持Unicode字符。
-# 转义字符的处理
-在 SQL 语句中使用字符串常量时，如果包含反斜杠序列或元字符（如`\d`、`\s`、`*`、`?`），这些转义字符会被自动转义。例如，`SELECT '\\' AS col;` 的输出将是 `\`。对于表中实际存储的值为 `\\` 的情况，不会发生转义，只有字符串常量会经历这种转义。
-
-因此，当编写需要匹配这些特殊序列的正则表达式时，需要添加额外的转义字符。例如：
-
-```SQL
--- 在字符串常量中，反斜杠序列会被自动转义
-SELECT '\\\\' as col1, '\\' as col2;
-+------+------+
-| col1 | col2 |
-+------+------+
-| \\   | \    |
-+------+------+
--- 如果在表中存储的是\\，则不会有自动转义的情况
-CREATE TABLE test_regex(col STRING);
-INSERT INTO test_regex VALUES('\\');
-SELECT * FROM test_regex;
-+-----+
-| col |
-+-----+
-| \\  |
-+-----+
-```
-
-使用正则表达式进行匹配时，需要对含有反斜杠序列或元字符的字符串进行转义：
-
-```SQL
-SELECT col, RLIKE(col, '\\\\') FROM test_regex;
-+-----+---------------------+
-| col | RLIKE(col, '\\\\') |
-+-----+---------------------+
-| \\  | TRUE                |
-+-----+---------------------+
-```
-
-# 字符串前缀 r 的使用
-
-为了避免在不确定何时需要转义的情况下手动处理转义字符，Lakehouse 支持在字符串前添加 `r` 前缀，表示 [字符串](<STRING.md>) 中的转义字符不会被转义，可以直接输入到正则表达式中运行。这样，用户可以像编写普通正则表达式一样，而不必担心 SQL 引擎的转义问题。例如：
-
-```SQL
--- 使用r前缀与表中的数据进行匹配
-SELECT col, RLIKE(col, r'\\') FROM test_regex;
-+-----+---------------------+
-| col | RLIKE(col, '\\\\') |
-+-----+---------------------+
-| \\  | TRUE                |
-+-----+---------------------+
--- 使用r前缀匹配字符串常量
-SELECT RLIKE(r'%SystemDrive%\Users\John', r'%SystemDrive%\\Users.*') as res;
-+------+
-| res  |
-+------+
-| TRUE |
-+------+
---不使用r前缀的正则匹配
-SELECT r'%SystemDrive%\Users\John' rlike '%SystemDrive\\\\\Users.*';
-+------+
-| res  |
-+------+
-| true |
-+------+
-```
-
-通过使用 `r` 前缀，Lakehouse 简化了正则表达式的使用，使得文本匹配和数据处理更加直观和高效。

-# REMOVE 命令
-
-## 概述
-
-REMOVE 命令用于从云器 Lakehouse 的数据湖 Volume 对象中删除文件，同时实际存储与对象存储的文件也会删除。该命令支持在 Studio 和 Lakehouse 客户端中运行。
-
-## 使用场景
-
-* 可以结合Lakehouse定时调度任务将已经导入到lakehouse的文件定时删除
-
-## 语法
-
-```
-REMOVE 
-    [ VOLUME volume_name | TABLE VOLUME table_name | USER VOLUME ]
-    [ SUBDIRECTORY 'dir' | FILE 'file' ] 
-```
-
-## 参数说明
-
-* `VOLUME/TABLE VOLUME/USER VOLUME`：分别指将外部 Volume，TABLE VOLUME 和USER VOLUME 中的数据删除。
-* `SUBDIRECTORY/FILE`：指定下载文件包括的范围，可以是 volume 中的子目录。指定目录会将下面的所有文件删除（`SUBDIRECTORY`），也可以利用 FILE 参数删除多个文件。
-
-## 示例
-
-删除volume中的某个目录
-
-```SQL
-REMOVE VOLUME my_volume SUBDIRECTORY 'delta-format/uploaddelta';
-```

-## 功能概述
-
-**历史版本恢复**：
-使用本命令，您可以将未删除的表或动态表恢复到指定的历史版本。借助时间旅行功能，您可以轻松地将表状态回滚到过去的某个时刻，以便在需要时恢复数据。
-
-**数据保留周期**：
-对象的历史恢复能力取决于数据的保留周期。当前预览版本的数据保留周期默认为7天，未来将调整为1天。您可以通过执行[ALTER命令](TIMETRAVEL.md)来调整保留周期。请注意，修改保留周期可能会增加存储成本。本功能支持表（TABLE）和动态表（DYNAMIC TABLE），不支持物化视图。
-
-## 语法示例
-
-```SQL
-RESTORE TABLE table_name TO time_travel_version;
-time_travel_version ::= 
-    TIMESTAMP AS OF timestamp_expression;
-```
-
-## 参数说明
-
-1. **table\_name**：指定未删除的表名，可以是TABLE、DYNAMIC TABLE或MATERIALIZED VIEW。若表已被删除，请使用[UNDROP](UNDROP-TABLE.md)命令进行恢复。
-2. **time\_travel\_version**：指定要恢复的表版本。先使用 `DESC HISTORY table_name` 查看版本时间点，再通过`TIMESTAMP AS OF`子句来指定具体的时间点。`timestamp_expression` 是一个返回时间戳类型表达式的参数，例如：
-
-* `'2023-11-07 14:49:18'`，即可强制转换为时间戳的字符串。
-* `CAST('2023-11-07 14:49:18' AS TIMESTAMP)`。
-* `CURRENT_TIMESTAMP() - INTERVAL 12 HOURS`：12小时之前的版本。
-* 任何本身是时间戳类型或可强制转换为时间戳的表达式。
-
-## 使用案例
-
-**案例 1：使用 RESTORE 命令恢复普通表到指定版本**
-
-```SQL
--- 查看表的变更历史
-DESC HISTORY json_table;
-
--- 使用 RESTORE 命令恢复到指定版本
-RESTORE TABLE json_table TO TIMESTAMP AS OF '2024-01-26 17:44:45.349';
-SELECT * FROM json_table;

-# 了解和使用Result Cache
-
-## 简介
-
-云器 Lakehouse 使用缓存技术来提升查询性能和效率。平台提供了三种类型的缓存来提高查询性能：
-
-1. 查询结果缓存（Result Cache）
-2. 元数据缓存（Metadata Cache）
-3. 虚拟集群本地缓存（Virtual Cluster Local Disk Cache）
-
-    ![](.topwrite/assets/image_1713780513737.png)
-
-其中：
-
-* 元数据缓存和查询结果缓存服务从属于服务层，可在工作空间内共享。
-* 虚拟集群本地缓存保存在集群本地节点，仅在使用指定虚拟集群时才能使用其本地缓存。
-
-本文将介绍查询结果缓存的工作原理及其使用方式。
-
-## 结果缓存
-
-在云器 Lakehouse 中执行查询时，符合一定条件的查询结果会自动保留一段时间，并在该时间段结束后被清除。这部分临时存储的查询结果称为查询结果缓存。
-
-查询结果缓存（Result Cache）需要满足以下条件才能被复用：
-
-* 查询中使用的表的基础数据未发生改变。如果查询中使用的任何表中的数据发生更改，则无法复用结果缓存；
-* 查询中没有包含对视图的引用。如果查询对象中包含视图，则不支持保留查询结果缓存；
-* 新发起的 SQL 查询语句在语法上能够和先前执行过的查询精确匹配；
-* 查询中不包含非确定性函数（例如：CURRENT_TIMESTAMP()）或用户定义函数 (UDF)；
-* 先前的Result Cache未过期删除。
-
-## 结果缓存的过期周期
-
-结果缓存成功后，默认保留周期为24小时。
-
-在 24 小时内，若有后续查询复用了该结果缓存，则其过期时间将额外延长 24 小时。否则，24 小时后，该查询结果缓存将被清除。
-
-## 启用与禁用结果缓存
-
-使用 `cz.sql.enable.shortcut.result.cache` 参数在 SESSION 级别启用或禁用，如下所示。
-
-```Python
---开启结果缓存
-set cz.sql.enable.shortcut.result.cache=true;
-
---关闭结果缓存
-set cz.sql.enable.shortcut.result.cache=false;
-```
-
-注：当前（2024 年 04 月）Lakehouse 版本的查询结果缓存（Result Cache）功能处于公测阶段，默认未开启，后续版本将默认开启。
-
-## 约束与限制
-
-缓存保留周期：24小时。
-
-单个工作空间支持缓存的作业数量上限：10万。
-
-结果缓存大小限制：无限制。小于等于10MB的结果将缓存在管控层内存Cache，超过10MB的结果将持久化在存储层（对象存储文件）。
-
-不支持包含非确定性函数、UDF 的查询结果缓存。
-
-## 结果缓存演示
-
-为了演示查询结果缓存，首先启用结果缓存并在云器 Lakehouse 中执行一个 SQL 查询。然后重新运行相同的查询，以验证新查询是否通过重用结果缓存实现了加速。
-
-```Sql
- --开启结果缓存
-set cz.sql.enable.shortcut.result.cache=true;
-
- select
-        l_returnflag,
-        l_linestatus,
-        sum(l_quantity) as sum_qty,
-        sum(l_extendedprice) as sum_base_price,
-        sum(l_extendedprice * (1 - l_discount)) as sum_disc_price,
-        sum(l_extendedprice * (1 - l_discount) * (1 + l_tax)) as sum_charge,
-        avg(l_quantity) as avg_qty,
-        avg(l_extendedprice) as avg_price,
-        avg(l_discount) as avg_disc,
-        count(*) as count_order
-from
-        tpch_100g_new.lineitem
-where
-        l_shipdate <= date '1998-12-01' - interval '85' day
-group by
-        l_returnflag,
-        l_linestatus
-order by
-        l_returnflag,
-        l_linestatus
-;
-```
-
-第一次执行花费了12.1秒。通过Job Profile查看作业运行信息，作业从磁盘读取了大量数据。
-
-![](.topwrite/assets/4590d8b1-4fd3-45b6-abd2-816d8ca58242.png)
-
-第二次执行该查询时，作业复用了上次查询的结果缓存，在 15 ms 内返回了结果。
-![](.topwrite/assets/result_cache_query_output.png)
-![](.topwrite/assets/383621f0-27c0-4f17-b217-0c0ad3bbc686.png)
-查看作业的 Job Profile 时，可在诊断页面的执行计划图中看到作业使用了“JOB RESULT REUSE”，说明作业直接查询了结果数据。

-# REVOKE FROM SHARE 语句
-
-## 功能描述
-
-`REVOKE FROM SHARE` 语句用于取消已分享的表（table）或视图（view）的权限。通过执行该语句，可以撤销其他用户或角色对分享对象的访问权限。
-
-仅支持修改类型（kind属性）为'OUTBOUND'（对外分享）的分享对象。其他服务实例分享进入的分享对象（share）不可移除数据对象。
-
-## 语法格式
-
-```SQL
-REVOKE [PERMISSIONS] ON {TABLE table_name | VIEW view_name} FROM SHARE share_name;
-```
-
-**参数说明**
-
-* `PERMISSIONS`：指定要撤销的权限，可选值为 `select`（用于查询数据）和 `read metadata`（用于查看表或视图的元数据）。
-* `TABLE table_name`：指定要撤销权限的表名。
-* `VIEW view_name`：指定要撤销权限的视图名。
-* `share_name`：指定要操作的分享名称。
-
-## 使用示例
-
-1. 撤销用户对分享表的查询权限和元数据查看权限：
-
-   ```SQL
-   REVOKE select, read metadata ON TABLE share_demo_table FROM SHARE share_demo;
-   ```
-
-2. 仅撤销用户对分享视图的查询权限：
-
-   ```SQL
-   REVOKE select ON VIEW share_demo_view FROM SHARE share_demo;
-   ```
-
-3. 撤销用户对分享表的元数据查看权限，但保留查询权限：
-
-   ```SQL
-   REVOKE read metadata ON TABLE share_demo_table FROM SHARE share_demo;
-   ```
-
-## 注意事项
-
-* 执行 `REVOKE FROM SHARE` 语句前，请确保您具有足够的权限来撤销分享对象的权限。
-* 被撤销权限的用户或角色将无法再访问指定的表或视图。
-* 如果需要重新授予权限，可使用 `GRANT` 语句进行操作。
-
-通过以上内容，您可以更好地理解和使用 `REVOKE FROM SHARE` 语句来管理分享对象的权限。

-## RIGHT 函数：从字符串右侧提取指定长度的字符
-
-RIGHT 函数用于从给定字符串的右侧开始提取指定数量的字符。这个函数在处理文本数据时非常有用，尤其是在需要根据特定规则截取字符串的场景下。
-
-### 函数语法
-
-```sql
-RIGHT(string, length)
-```
-
-- `string`：要提取字符的原始字符串。
-- `length`：要提取的字符数量，必须是一个大于或等于零的整数。
-
-### 函数行为说明
-
-- 如果 `length` 等于 0，函数返回一个空字符串。
-- 如果 `length` 大于 `string` 的长度，函数返回 `string` 本身。
-- 如果 `length` 小于 0，函数返回 NULL。
-- 如果 `string` 为 NULL，函数返回 NULL。
-
-### 实际应用案例
-
-**案例 1：提取学生姓名的后两个字符**
-
-假设有一个名为 `student` 的表，其中包含学生的姓名（name）和性别（gender），如下所示：
-
-| id | name  | gender |
-|----|-------|--------|
-| 1  | Alice | F      |
-| 2  | Bob   | M      |
-| 3  | Cathy | F      |
-| 4  | David | M      |
-
-现在，我们想要查询每个学生姓名的后两个字符，可以使用以下 SQL 语句：
-
-```sql
-SELECT name, RIGHT(name, 2) AS suffix FROM student;
-```
-
-查询结果如下：
-
-| name  | suffix |
-|-------|--------|
-| Alice | ce     |
-| Bob   | ob     |
-| Cathy | hy     |
-| David | id     |
-
-**案例 2：提取文件名的扩展名**
-
-假设我们有一个包含文件名的字符串，现在需要提取其扩展名（即文件名中最后一个点号之后的部分）。例如，字符串 `"report.xls"` 的扩展名是 `"xls"`。
-
-```sql
-SELECT RIGHT('report.xls', 4) AS file_extension;
-```
-
-查询结果为：
-
-| file_extension |
-|----------------|
-| xls            |
-
-**案例 3：处理长度不足的情况**
-
-假设我们需要提取字符串末尾的若干字符，但字符串本身的长度可能小于要提取的字符数。例如，处理以下字符串：
-
-- `"这是一个示例文本"`（长度为 9）
-- `"示例"`（长度为 2）
-
-使用 RIGHT 函数提取最后 3 个字符：
-
-```sql
-SELECT RIGHT('这是一个示例文本', 3) AS last_three_chars;
-SELECT RIGHT('示例', 3) AS last_three_chars;
-```
-
-结果如下：
-
-| last_three_chars |
-|------------------|
-| 例文本           |
-| 示例             |

-# 函数名称：RLIKE
-
-## 功能描述
-`RLIKE` 函数用于检查一个字符串是否符合指定的正则表达式模式。它既可以作为操作符使用，也可以作为函数调用，提供灵活的字符串匹配能力。
-
-## 语法
-- 作为操作符使用：
-  ```sql
-  str [NOT] RLIKE regex
-  ```
-- 作为函数使用：
-  ```sql
-  RLIKE(str, regex)
-  ```
-
-## 参数
-- `str`：要检查的字符串。
-- `regex`：用于匹配的正则表达式。
-
-## 返回值
-- 返回布尔值，如果字符串符合正则表达式模式，则返回 `TRUE`；否则返回 `FALSE`。
-- 如果使用 `[NOT] RLIKE` 作为操作符，返回值相反，即不符合模式时返回 `TRUE`。
-
-
-## 使用示例
-
-以下是 RLIKE 函数的使用示例：
-
-1. 匹配字符串开头：
-
-   ```sql
-   select rlike('aabb', r'^a');
-   -- 结果为true，因为字符串'aabb'的开头是'a'
-   ```
-
-2. 匹配字符串开头和结尾：
-
-   ```sql
-   select rlike('aabb', r'^a.*b$');
-   -- 结果为true，因为字符串'aabb'的开头是'a'，结尾是'b'
-   ```
-
-3. 使用通配符匹配任意字符：
-
-   ```sql
-   select rlike('footerbar', r'foo(.*?)(bar)');
-   -- 结果为true，因为正则表达式中的'.*?'可以匹配任意长度的任意字符
-   ```
-
-4. 匹配邮箱地址：
-
-   ```sql
-   select rlike('user@example.com', r'^[a-zA-Z0-9._%-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$');
-   -- 结果为true，因为该正则表达式可以匹配大多数有效的电子邮箱地址
-   ```
-
-5. 匹配电话号码：
-
-   ```sql
-   select rlike('123-4567-8900', r'\d{3}-\d{4}-\d{4}');
-   -- 结果为true，因为该正则表达式可以匹配特定格式的电话号码
-   ```
-6. 使用 NOT RLIKE
-    ```sql
-    -- 使用作为函数
-    SELECT RLIKE('hello world', 'hello.*world') AS result;
-    -- 返回 TRUE
-    
-    -- 使用作为操作符
-    SELECT 'hello world' RLIKE r'hello.*world' AS result;
-    -- 返回 TRUE
-    
-    -- 使用 NOT 操作符
-    SELECT 'hello world' NOT RLIKE r'hello.*world' AS result;
-    -- 返回 FALSE
-    ```

-# 2024年11月12日— 0.9 Lakehouse Platform 产品更新发布说明
-
-本次发布（Release 2024.11.12），我们引入了一系列新功能、增强特性以及修复项。这些更新将分阶段逐步推送至以下区域，预计在发布日起一周至两周内完成。具体时间依据您所在的区域而定。
-
-* 阿里云上海区
-* 腾讯云上海区
-* 腾讯云北京区
-* 腾讯云广州区
-* 亚马逊北京区
-* 国际站-阿里云-新加坡区
-* 国际站-AWS-新加坡区
-
-## 数据湖易用性增强
-
-* **自动Schema探查**：支持对Volume存储中可结构化的文件格式（如csv、parquet、orc文件）自动探查schema，无需预先了解列名和数据类型信息。
-
-* **联邦查询功能拓展**：
-
-  * 新增对Databricks Unity Catalog的联邦查询支持
-  * hive联邦查询：当hive表中是iceberg格式时，支持iceberg格式读取
-
-## 智能化
-
-* **Auto Index**：自动推荐cluster key和sort key，推荐的列可以用来做sort key，挑选的是经常出现在过滤语句中的列。如果将这些列设置为表的sort key，可以加快query的执行速度。
-
-## 增量计算
-
-* **动态表支持DML命令**：支持使用DML命令直接进行数据订正。使用DML修改数据后，下一次刷新将为全量刷新。目前支持INSERT, DELETE, TRUNCATE，暂不支持MERGE INTO, UPDATE。默认情况下，DML修改DT的内容会报错，防止用户误操作。如需操作，请设置`set cz.sql.dt.allow.dml = true;`。
-* **新增分区动态表**：动态分区表通过`SESSION_CONFIGS()['dt.arg.xx']`进行定义，刷新时会增量刷新。 刷新时必须使用显示指定分区的刷新命令`REFRESH DYNAMIC TABLE dt PARTITION partition_spec;`。如果参数使用在普通表，虽然lakehouse没有限制语法但是普通表会全量刷新，刷新语法为`REFRESH DYNAMIC TABLE dt ;`
-
-## SQL能力更新
-
-### 语法支持
-
-* cte语法中支持insert into写到开头。如下案例
-
-```SQL
---新增语法insert into insert_dest with data as (select 2)select * from data;--之前的语法with data as (select 3) insert into insert_dest with data2 as (select * from data) select * from ddata2
-```
-
-### 函数支持
-
-| 函数名称   | 功能               |
-| ------ | ---------------- |
-| unnest | 函数用于将数组中的元素展开为多行 |
-
-## SDK接口
-
-* JDBC接口新增对vector类型的支持。
-
-## 行为变更
-
-* **增量计算动态表**：在新版本中，如果用户不是简单地删除列/添加列/修改SELECT定义语句，添加列定义只能是从表一路经由SELECT透传的，不能参与任何会影响其他列的计算时则会增量刷新。如果新增的列参与了计算在Create Or Replace发生后，REFRESH任务会退化为一次全量刷新。
-
-* **Quota约束限制**：
-
-  * **Trial账户限制**：单实例下数据对象总数量限制为1000个
-
-* **数据导入**：
-
-  * **Kafka Pipe调整**：将最小间隔从原来的1秒调整为10秒

-# 角色
-
-## 角色（Role）定义
-
-在Lakehouse中，**角色**是一种授权管理的工具，用于将若干个权限点集中在一起，然后再将此角色授予给一个或多个用户（User）。
-
-* 当用户被授予角色后，用户即拥有该角色包含的所有权限。
-* 角色也可被授予更多的权限点，从而实现权限的灵活扩展与管理。
-
-相较于直接对用户逐个授予权限（ACL 模式），通过“角色”来分配权限，可以显著简化管理流程，也更易于维护和审计。因此，推荐在日常的权限管理中，充分使用 **基于角色的访问控制（RBAC，Role-Based Access Control）**。
-
-## 角色类型
-
-Lakehouse中的角色分为两种类型：**预置角色**和**自定义角色**。
-
-1. **预置角色**
-
-   * 预置角色是平台在服务实例创建时自动配置的角色，**不可修改其权限**或**删除**，但可以将预置角色直接授予用户。
-   * 平台预置多个角色，涵盖从实例层面的管理到工作空间层面的管理与使用，帮助用户快速完成基本授权并使用产品功能。全部系统预置角色及其默认权限详见 [系统内置角色权限列表](permissions-of-built-in-workspace-level-roles.md)
-
-2. **自定义角色**
-
-   * 用户可根据自身业务需要，在**工作空间**范围内创建自定义角色，对该角色进行灵活的权限配置与维护。
-   * 自定义角色的权限可随时修改或删除，以便适应不断变化的业务场景需求。
-   * **注意**：目前仅支持在工作空间内创建自定义角色，不支持在实例级别创建自定义角色。创建自定义角色的操作仅支持使用 SQL 执行，暂不支持 Web 端操作。

-大数据平台将元数据对象区分为“**实例级**”和“**工作空间级**”两类，角色也相应分为“**实例角色**”和“**空间角色**”：
-
-**实例角色（Instance Role）**：实例级别角色有两个使用场景：1) 用于实例级资源和操作的全局管控；2) 用于跨多个工作空间的权限授予。
-
-**工作空间角色（Workspace Role）**：作用于特定工作空间范围内的对象（如 schema、table、virtual cluster 等）。工作空间角色以工作空间为边界，互不影响。
-
-## 角色的管理与使用
-
-### 查看角色
-
-可在“管理” > “安全” > “角色”列表中，查看当前实例与工作空间内的角色信息。
-
-或在“管理” > “工作空间”列表中点击进入工作空间详情页，切换到“角色”页签，查看工作空间下的所有角色。
-
-或在SQL中执行以下语句，查询当前连接的工作空间内所有工作空间级别角色：
-
-```
-SHOW ROLES;
-```
-
-### 将角色授予用户
-
-当一个自定义角色创建并具备了相应权限后，需要将该角色授予给用户，用户才能实际使用该角色所包含的权限。
-
-可通过Web端或SQL方式将角色授予用户。
-
-**Web端操作**
-
-在“安全” > “角色”页面，可以查看当前实例下的实例级别角色和工作空间级别角色。
-
-:-: ![](.topwrite/assets/image_1734878372389.png =784)
-
-对任一角色进行授权操作时，点击该角色名称，进入角色详情页，此时可以查看该角色已被授予的所有用户。点击“+ 授予用户”，在弹窗中勾选需要添加的用户，点击“授权”，即可将角色授予用户。
-:-: ![](.topwrite/assets/image_1734878510613.png =798)
-
-要移除已被授予角色的用户时，点击用户名右侧的“...”，选择“移除用户”，即可取消该用户使用这个角色的权限。
-
-在“管理” > “工作空间”列表进入工作空间详情页面，在“角色”页签也可以查看该空间内的角色列表，并通过上述操作将该角色授予或取消授予用户。
-
-:-: ![](.topwrite/assets/image_1734878871234.png =795)
-
-**SQL操作**
-
-仅工作空间级别的用户支持使用 SQL 操作进行授权。在工作空间内执行以下语句，可将空间内角色授予指定用户。
-
-```SQL
-Grant ROLE <ROLE_NAME> TO USER <USER_NAME>;
-```
-
-执行以下语句可移除角色中的指定用户：
-
-```SQL
-REVOKE ROLE <ROLE_NAME> FROM USER <USER_NAME>;
-```
-
-### 创建用户自定义角色
-
-当前仅支持创建工作空间级别的自定义角色，需要使用具备该工作空间管理员（workspace_admin）角色的用户进行操作。仅支持使用 SQL 创建自定义角色。
-
-**创建语法示例**：
-
-```
-CREATE ROLE <ROLE_NAME>;
-```
-
-### 给自定义角色添加权限
-
-在工作空间内，可通过 GRANT 语句为自定义角色添加权限。示例：
-
-```
--- 授予某自定义角色对 schema my_schema 下所有表的读写权限
-GRANT SELECT, READ METADATA, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA my_schema
-TO ROLE my_custom_role;
-```
-
-## 常见问题
-
-1. **角色和 ACL（访问控制列表）的区别是什么？**
-
-   * ACL 直接将权限授予给用户；而角色将权限“打包”后再授予用户。
-   * 对于部门人员变动频繁或权限配置复杂的场景，建议优先使用角色方式减少重复操作。
-
-2. **是否支持多角色叠加权限？**
-
-   * 支持。一个用户可被授予多个角色，最终生效的权限是各角色权限范围的并集。
-
-3. **实例角色是否可以访问工作空间？**
-
-   * 否。实例角色与工作空间角色互不影响，实例角色不具备也无法获取工作空间级对象的权限。
-
-4. **预置角色能否修改或删除？**
-
-   * 不可以。预置角色是系统内置、不可变动的角色，只能选择是否授予用户。

-# 使用样例数据快速开始查询分析
-
-## 教程概述
-
-通过本教程，您将了解如何利用 Lakehouse 平台内置的样例数据集，无需提前准备数据即可快速使用 SQL 进行查询分析，以评估其功能及性能。
-
-样例数据集由云器平台通过名称为CLICKZETTA\_SAMPLE\_DATA的数据集以共享方式开放给所有账户查询。本教程将以其中的 TPC-H 100GB 数据集为例，介绍如何在 Lakehouse 中快速完成 TPC-H 测试集的查询测试，评估处理性能。
-
-本教程将按以下步骤进行：
-
-* 环境准备：通过样例数据集检查原始数据，创建测试使用的计算集群
-* 发起查询：使用 Studio Web 环境创建 SQL 查询，完成 22 个 TPC-H SQL 查询
-* 变更集群大小：调整集群大小，扩大至之前集群大小的 4 倍
-* 发起查询：使用调整大小后的集群再次完成 22 个 TPC-H SQL 查询
-* 观察不同集群规格下，查询时延的变化
-
-## Step01. 准备工作
-
-首先，登录 Lakehouse Web 控制台并进入指定的工作空间后，可访问“数据”模块，检查数据管理下的数据对象列表中“clickzetta_sample_data.tpch_100gb”下的相关表是否存在。
-![](.topwrite/assets/image_1716285499384.png)
-
-其次，我们将为本次测试临时创建一个独立的计算集群用于查询分析。您可以通过访问 Lakehouse Web 控制台的“计算 → 集群”菜单，通过页面向导新建集群。
-![](.topwrite/assets/tpch_100g_vc.png)
-
-同时，您也可以通过 SQL 命令来创建集群。使用 SQL 命令操作时，您可以在不离开 SQL 开发上下文的情况下，在 Ad-hoc 或 ETL 开发过程中通过 SQL 命令控制集群的创建、扩/缩容、暂停/恢复、销毁等操作，这通常可以提高计算资源的操作效率。
-
-本教程中，通过在“开发”模块新建 SQL 脚本任务并执行以下脚本，即可快速创建集群。
-![](.topwrite/assets/image_1716953675576.png)
-
-```sql
--- 创建分析型虚拟计算资源
-create vcluster if not exists TPCH_100GB vcluster_size='Medium' vcluster_type='Analytics'  AUTO_RESUME=TRUE AUTO_SUSPEND_IN_SECOND=300 min_replicas=1 max_replicas=1 comment 'TPCH 100GB TEST';
-```
-
-> 注：计算集群的 vcluster_size 参数同时支持以 T-shirt size（XSMALL、SMALL、LARGE 等）和以数字（1, 2, 4, 16 等）表达的方式，以提供更丰富的计算集群规格，满足不同场景的需要。更多信息详见：[计算集群规格代码变更说明](vcluster_size_description.md)
-
-^
-
-## Step02. 对样例数据进行TPC-H的查询
-
-在“开发”模块新建 SQL 脚本任务，录入 TPC-H 的 22 个查询语句，在“集群”下拉列表中选择刚才创建的测试集群，然后选中任务中的全部脚本并点击“运行”按钮进行串行查询。
-![](.topwrite/assets/image_1716953736183.png)
-
-查询脚本为：
-
-```sql
--- 执行使用TPCH_100GB计算资源运行作业
-use vcluster TPCH_100GB;
-
--- 设置查询的标签
-set query_tag='tpch100g_benchmark';

-执行完毕后，可通过当前 SQL Editor 的运行历史查看本次任务的运行耗时。
-![](.topwrite/assets/image_1716953511204.png)
-
-如果您希望进行性能测试，可连续执行2次以上的查询，以便计算集群能够充分Cache数据发挥最佳性能。同时，云器 Lakehouse 也提供了系统主动缓存（Cache）功能，本教程暂不展开这部分介绍。以下是第二次运行时，计算集群缓存（Cache）数据后的运行结果，较第一次无缓存时性能有明显提升。
-![](.topwrite/assets/image_1716954084738.png)
-
-如果希望查看 22 个查询中每个查询的执行详情，可通过访问“计算 → 作业历史”，根据查询标签“tpch100g_benchmark”对查询历史进行过滤后查看。

-
-## Step03. 扩大集群规格，再次对样例数据进行 TPC-H 的查询
-
-通过“计算 → 集群”管理页面，您可以修改刚才创建的测试集群的规格大小，例如从 M 修改为 L，L 规格是 M 规格的 2 倍。
-![](.topwrite/assets/tpch_vc_edit_to_L.png)
-
-或者在SQL脚本中执行以下命令进行修改：
-
-```sql
--- 修改集群大小
-alter vcluster TPCH_100GB SET VCLUSTER_SIZE = 'LARGE';
-```
-
-修改后，使用调整大小后的集群再次进行查询测试。
-![](.topwrite/assets/image_1716954399887.png)
-新扩容的计算节点在数据被充分缓存（Cache）后，性能会继续提升。
-![](.topwrite/assets/image_1716954453780.png)
-![](.topwrite/assets/image_1716954471528.png)
-
-通过作业的运行时间可以观察到，在相同的数据规模和查询任务下，扩大计算集群规格后，任务的总体运行时间大幅缩短。在两次执行后，随着数据被缓存，查询性能得到进一步提升。

-
-## 2. 网络安全
-
-云器Lakehouse支持SSL/TLS加密传输，确保数据在传输过程中的安全性。租户可以通过设置IP白名单策略，控制可访问其Lakehouse服务实例的网络地址范围。例如，租户可以将公司内部的IP地址添加到白名单中，以仅允许来自这些地址的访问。
-
-## 3. 访问控制
-
-云器Lakehouse通过工作空间实现对数据和计算资源的进一步隔离。只有加入工作空间的用户才能访问其中的数据和计算资源。此外，云器Lakehouse提供ACL（访问控制列表）和RBAC（基于角色的访问控制）两种授权方式，允许用户根据业务需求自定义角色，并进行表级别粒度的授权。
-
-例如，管理员可以为数据分析师创建一个工作空间，并为其分配相应的角色和权限，以便他们能够访问和处理特定的数据表。
-
-## 4. 审计与监控
-
-云器Lakehouse记录了对数据的所有操作，这些历史记录为只读且不可编辑，保存时间长达6个月。同时，平台提供监控和报警功能，帮助用户及时感知作业异常、数据异常等情况，并根据报警的严重程度发送通知。
-
-例如，当某个作业执行失败时，系统会自动发送报警通知给管理员，以便其能够及时采取措施解决问题。
-
-## 5. 数据加密
-
-云器Lakehouse对敏感数据（如账户信息）进行加密存储，确保数据在整个生命周期中的安全性。用户可以通过配置数据加密功能来进一步保护数据。当数据加密功能启用后，数据将在写入Lakehouse后的全生命周期内保持加密存储，仅在租户专属的计算节点处理数据时进行解密。
-
-例如，当企业需要存储和处理涉及个人隐私的数据时，可以启用数据加密功能，以确保数据的安全性。
-
-## 6. 数据容灾与恢复
-
-云器Lakehouse依托云服务商IaaS层的存储服务，基于多副本、高可用的云基础设施搭建，具备极高的服务可用性和数据可靠性。此外，平台默认提供1天的数据恢复功能，有效降低数据误删除、误修改风险，加强对数据完整性的保护。

-# 语义视图（Semantic View）
-
-## 概述
-
-语义视图是云器 Lakehouse 中的一种架构级逻辑数据模型对象，用于弥合业务用户描述数据的方式与数据在数据平台中实际存储方式之间的差距。
-
-如果没有语义视图，不同的报表和应用中可能存在不一致的计算方式，导致偏差结果。语义视图作为面向业务的抽象层，解决了以下常见问题：
-
-* **对于数据分析**：语义视图提供了统一的指标和维度定义，使业务用户无需编写复杂的 JOIN 语句即可查询跨表数据，显著降低了 SQL 编写门槛。
-* **对于数据治理**：语义视图以声明式方式集中管理表关系、维度和指标的定义，确保组织内部所有利益相关方——从数据分析师到业务用户——使用的都是相同的数据口径。
-
-***
-
-## 语义视图中的概念
-
-语义视图由以下核心组件构成：
-
-**逻辑表（TABLES**）：在语义视图中，您定义的逻辑表通常对应业务实体，如客户、订单或商品明细。每个逻辑表映射到一张物理表，并通过主键和外键声明表间关系。您可以通过外键定义逻辑表之间的连接关系，从而实现跨实体的数据分析——就像在数据库中连接物理表一样，但无需在查询时手动编写 JOIN。
-
-**维度（DIMENSIONS**）：维度是分类属性，为指标提供上下文含义。它们通过将数据分组为有意义的类别来回答"谁"、"什么"、"哪里"和"何时"等问题，例如订单日期、客户名称或订单年份。
-
-**指标（METRICS**）：指标是通过对列进行聚合计算（如 `SUM`、`AVG`、`COUNT`）得出的量化业务度量。它们将原始数据转化为有意义的业务指标，例如"客户总数"或"平均订单价值"。指标代表了报表和仪表盘中驱动业务决策的 KPI。
-
-**过滤器（FILTERS**）：过滤器是预定义的、可重用的过滤条件，用于在语义视图中封装常用的业务筛选逻辑。
-
-***
-
-## 创建语义视图
-
-### 语法
-
-```sql
-CREATE SEMANTIC VIEW <视图名称>
-TABLES (
-    <逻辑表定义> [ , ... ]
-)
-[ FILTERS (
-    <过滤器定义> [ , ... ]
-) ]
-DIMENSIONS (
-    <维度定义> [ , ... ]
-)
-METRICS (
-    <指标定义> [ , ... ]
-)
-[ COMMENT = '<视图说明>' ]
-;
-```
-
-其中，各子句的定义语法如下：
-
-#### 逻辑表定义
-
-```sql
-<表别名> AS <架构名>.<物理表名>
-    PRIMARY KEY ( <列名> [ , ... ] )
-    [ FOREIGN KEY ( <列名> ) REFERENCES <其他逻辑表别名> ]
-    [ WITH SYNONYMS ( '<同义词>' [ , ... ] ) ]
-    [ COMMENT = '<说明>' ]
-```
-
-#### 过滤器定义
-
-```sql
-<逻辑表别名>.<过滤器名> AS <布尔表达式>
-```
-
-#### 维度定义
-
-```sql
-{ <逻辑表别名>.<维度名> | <维度名> } AS <表达式>
-    [ WITH SYNONYMS = ( '<同义词>' [ , ... ] ) ]
-    [ is_unique = { true | false } ]
-    [ is_time = { true | false } ]
-    [ enum_values = [ <值1>, <值2>, ... ] ]
-    [ COMMENT = '<说明>' ]
-```
-
-#### 指标定义
-
-```sql
-<逻辑表别名>.<指标名> AS <聚合表达式>
-    [ COMMENT = '<说明>' ]
-```
-
-### 参数说明
-
-**逻辑表定义参数**：
-
-| 参数                                          | 说明                                                                  |
-| ------------------------------------------- | ------------------------------------------------------------------- |
-| `<表别名> AS <架构名>.<物理表名>`                     | 为物理表指定一个逻辑别名。在后续的外键引用、维度和指标定义中，均使用此别名来引用逻辑表                         |
-| `PRIMARY KEY ( <列名> [ , ... ] )`            | 指定逻辑表中作为主键的一列或多列。主键有助于确定表之间的关系类型（如一对多或一对一）                          |
-| `FOREIGN KEY ( <列名> ) REFERENCES <其他逻辑表别名>` | 定义当前逻辑表与另一个逻辑表之间的外键关系。引用目标必须使用逻辑表别名（而非物理表名）。语义视图在查询时会根据此外键关系自动处理表连接 |
-| `WITH SYNONYMS ( '<同义词>' )`                 | 为逻辑表定义同义词，增强可发现性                                                    |
-| `COMMENT = '<说明>'`                          | 为逻辑表添加描述性注释                                                         |
-
-**维度定义参数**：
-
-| 参数                                       | 说明                                             |
-| ---------------------------------------- | ---------------------------------------------- |
-| `is_unique`                              | 标识该维度的值是否唯一。当设置为 `true` 时，表示该维度列中不包含重复值，例如客户名称 |
-| `is_time`                                | 标识该维度是否为时间类型。当设置为 `true` 时，表示该维度代表时间属性，例如订单日期  |
-| `enum_values`                            | 定义该维度允许的枚举值列表。这有助于约束维度的取值范围并提升查询准确性            |
-| `WITH SYNONYMS = ( '<同义词1>', '<同义词2>' )` | 为维度定义一个或多个同义词，使用户可以使用不同的业务术语来引用同一个维度           |
-
-**指标聚合函数**： `COUNT`、`AVG`、`SUM`、`MIN`、`MAX`
-
-### 使用说明
-
-* 在语义视图中，您必须至少定义一个维度或一个指标，即必须包含 `DIMENSIONS` 子句或 `METRICS` 子句。
-* 在 `TABLES` 子句中，被外键引用的逻辑表必须先于引用它的表进行定义。例如，如果 `orders` 表的外键引用了 `customers` 表，则 `customers` 的定义必须出现在 `orders` 之前，或至少在同一 `TABLES` 子句中已被声明。
-* 如果目标语义视图已存在，`CREATE SEMANTIC VIEW` 将报错。建议使用 `DROP SEMANTIC VIEW IF EXISTS` 语句先删除已有视图，以确保脚本的幂等性（可重复执行）。
-* 维度和指标支持两种命名方式：**限定名称**（`<逻辑表别名>.<名称>`，如 `orders.order_date`）和**短名称**（直接使用名称，如 `order_date`）。当维度或指标名称在语义视图中唯一时，可以使用短名称；如果存在同名冲突，则必须使用限定名称。
-* 维度支持将表达式作为定义，即**计算维度**。例如，`YEAR(o_orderdate)` 可从订单日期中提取年份，作为一个独立的维度使用。
-
-### 示例
-
-以下示例使用 TPC-H 数据集创建一个名为 `tpch_rev_analysis` 的语义视图，用于收入分析场景。该数据集包含客户、订单和订单明细等表，代表了一个简化的业务场景。
-
-该语义视图定义了：
-
-* 三个逻辑表（`orders`、`customers` 和 `line_items`），分别映射到 TPC-H 中的订单表、客户表和订单明细表。
-* `orders` 和 `customers` 之间的外键关系（通过 `o_custkey`）。
-* `line_items` 和 `orders` 之间的外键关系（通过 `l_orderkey`）。
-* 用于分组和过滤的维度：客户名称、订单日期和订单年份。
-* 量化的业务指标：客户总数和平均订单价值。
-
-#### 基础语义视图
-
-```sql
-DROP SEMANTIC VIEW IF EXISTS tpch_rev_analysis;
-CREATE SEMANTIC VIEW tpch_rev_analysis
-TABLES (
-    customers AS TPCH_SF1.CUSTOMER
-        PRIMARY KEY (c_custkey)
-        COMMENT = 'Main table for customer data',
-    orders AS TPCH_SF1.ORDERS
-        PRIMARY KEY (o_orderkey)
-        FOREIGN KEY (o_custkey) REFERENCES customers
-        WITH SYNONYMS ('sales orders')
-        COMMENT = 'All orders table for the sales domain',
-    line_items AS TPCH_SF1.LINEITEM
-        PRIMARY KEY (l_orderkey, l_linenumber)
-        FOREIGN KEY (l_orderkey) REFERENCES orders
-        COMMENT = 'Line items in orders'
-)
-DIMENSIONS (
-    customers.customer_name AS customers.c_name
-        WITH SYNONYMS = ('customer name')
-        COMMENT = 'Name of the customer',
-    orders.order_date AS o_orderdate
-        COMMENT = 'Date when the order was placed',
-    orders.order_year AS YEAR(o_orderdate)
-        COMMENT = 'Year when the order was placed'
-)
-METRICS (
-    customers.customer_count AS COUNT(c_custkey)
-        COMMENT = 'Count of number of customers',
-    orders.order_average_value AS AVG(orders.o_totalprice)
-        COMMENT = 'Average order value across all orders'
-)
-COMMENT = 'Semantic view for revenue analysis';
-```
-
-在上述示例中，`TABLES` 子句定义了三个逻辑表：一个包含 TPC-H 订单信息的 `orders` 表，一个包含客户信息的 `customers` 表，以及一个包含订单明细的 `line_items` 表。每个逻辑表通过 `PRIMARY KEY` 子句标识主键列，并通过 `FOREIGN KEY ... REFERENCES` 子句声明与其他逻辑表的关联关系。同义词和注释使逻辑表更易于被发现和理解。
-
-`DIMENSIONS` 子句定义了三个维度：`customer_name` 直接映射到客户表的 `c_name` 列；`order_date` 映射到订单日期列；`order_year` 是一个计算维度，通过 `YEAR()` 函数从订单日期中提取年份。
-
-`METRICS` 子句定义了两个指标：`customer_count` 使用 `COUNT` 聚合函数统计客户数量；`order_average_value` 使用 `AVG` 聚合函数计算平均订单价值。
-
-#### 带过滤器和维度元数据的语义视图
-
-以下示例在基础版本上增加了过滤器、维度唯一性标识、时间类型标识和枚举值约束，展示了语义视图的高级特性：
-
-```sql
-DROP SEMANTIC VIEW IF EXISTS tpch_rev_analysis;
-CREATE SEMANTIC VIEW tpch_rev_analysis
-TABLES (
-    customers AS TPCH_AI.CUSTOMER
-        PRIMARY KEY (c_custkey)
-        COMMENT = 'Main table for customer data',
-    orders AS TPCH_AI.ORDERS
-        PRIMARY KEY (o_orderkey)
-        FOREIGN KEY (o_custkey) REFERENCES customers
-        WITH SYNONYMS ('orders_synonyms')
-        COMMENT = 'All orders table for the sales domain',
-    line_items AS TPCH_AI.LINEITEM
-        PRIMARY KEY (l_orderkey, l_linenumber)
-        FOREIGN KEY (l_orderkey) REFERENCES orders
-        COMMENT = 'Line items in orders'
-)
-FILTERS (
-    customers.is_ny AS customers.c_city = 'New York'
-)
-DIMENSIONS (
-    customers.customer_name AS customers.c_name
-        WITH SYNONYMS = ('customer name', 'dimensions_synonyms')
-        is_unique = true
-        COMMENT = 'Name of the customer',
-    orders.order_date AS o_orderdate
-        is_time = true
-        enum_values = [date'2025-01-01', date'2025-06-01', date'2025-12-01']
-        COMMENT = 'Date when the order was placed',
-    orders.order_year AS YEAR(o_orderdate)
-        COMMENT = 'Year when the order was placed'
-)
-METRICS (
-    customers.customer_count AS COUNT(c_custkey)
-        COMMENT = 'Count of number of customers',
-    orders.order_average_value AS AVG(orders.o_totalprice)
-        COMMENT = 'Average order value across all orders'
-)
-COMMENT = 'Semantic view for revenue analysis';
-```
-
-在此示例中，`FILTERS` 子句定义了一个名为 `is_ny` 的过滤器，用于筛选城市为"New York"的客户记录。该过滤器封装了一个可重用的业务筛选条件，避免在多处查询中重复编写相同的 `WHERE` 子句。
-
-`customer_name` 维度设置了 `is_unique = true`，表示客户名称在数据集中是唯一的。`order_date` 维度设置了 `is_time = true`，表示该字段为时间属性，同时通过 `enum_values` 限定了该维度的允许取值为三个特定日期。
-
-> **注意**：`FILTERS` 子句中定义的命名过滤器（如 `is_ny`）是面向 AI/元数据层的语义注解，不能作为 `semantic_view()` 函数的参数直接传入。若要在查询中应用过滤条件，需将对应列定义为 `DIMENSION`，再通过外层 `WHERE` 子句实现过滤。
-
-***
-
-## 查询语义视图
-
-### 语法
-
-使用 `semantic_view()` 表函数在 `SELECT` 语句中查询语义视图：
-
-```sql
-SELECT *
-FROM semantic_view(
-    <视图名称>,
-    DIMENSIONS <维度名> [ , DIMENSIONS <维度名> ... ],
-    METRICS <指标名> [ , METRICS <指标名> ... ]
-);
-```
-
-在查询中，您可以使用限定名称（`<逻辑表别名>.<名称>`）或短名称（直接使用名称）来引用维度和指标。当名称在语义视图中唯一时，两种方式等效，返回相同的结果。
-
-### 使用说明
-
-* 查询结果会按指定的维度自动分组，并根据指标定义中的聚合函数计算指标值。语义视图引擎会根据 `TABLES` 子句中定义的外键关系自动处理所需的表连接，用户无需手动编写 JOIN 逻辑。
-* 维度在结果中的排列顺序与查询中指定的顺序一致。
-
-### 示例
-
-#### 使用限定名称查询单维度和单指标
-
-以下查询返回按订单日期分组的平均订单价值：
-
-```sql
-SELECT * FROM semantic_view(
-    tpch_rev_analysis,
-    DIMENSIONS orders.order_date,
-    METRICS orders.order_average_value
-);
-```
-
-输出示例：
-
-```
-2021-01-01    125.000000
-```
-
-#### 使用限定名称查询多维度
-
-以下查询按订单日期和客户名称两个维度分组，返回平均订单价值：
-
-```sql
-SELECT * FROM semantic_view(
-    tpch_rev_analysis,
-    DIMENSIONS orders.order_date,
-    DIMENSIONS customers.customer_name,
-    METRICS orders.order_average_value
-);
-```
-
-输出示例：
-
-```
-2021-01-01    Join    125.000000
-```
-
-#### 使用短名称查询
-
-当维度和指标名称在语义视图中唯一时，可以省略逻辑表别名前缀，直接使用短名称。以下查询与上一个示例等效：
-
-```sql
-SELECT * FROM semantic_view(
-    tpch_rev_analysis,
-    DIMENSIONS order_date,
-    DIMENSIONS customer_name,
-    METRICS order_average_value
-);
-```
-
-#### 使用 WHERE 子句过滤数据
-
-将需要过滤的列定义为维度后，可通过外层 `WHERE` 子句实现数据筛选（对应 `FILTERS` 中的命名条件）：
-
-```sql
-SELECT * FROM semantic_view(
-    tpch_rev_analysis,
-    DIMENSIONS customers.customer_city,
-    DIMENSIONS customers.customer_name,
-    METRICS orders.order_average_value
-) WHERE customer_city = 'New York';
-```
-
-### 传统 SQL 查询对比
-
-为了说明语义视图如何简化查询，以下对比展示了同一分析需求分别使用传统 SQL 和语义视图的写法。
-
-**传统 SQL 查询**：
-
-使用传统方式，您需要手动编写 JOIN 逻辑、指定连接条件，并显式声明 GROUP BY 子句：
-
-```sql
-SELECT
-    o.o_orderdate,
-    c.c_name,
-    AVG(o.o_totalprice) AS avg_value
-FROM TPCH_SF1.ORDERS o
-JOIN TPCH_SF1.CUSTOMER c ON o.o_custkey = c.c_custkey
-GROUP BY o.o_orderdate, c.c_name;
-```
-
-**语义视图查询**：
-
-使用语义视图时，您只需指定所需的维度和指标，语义视图引擎会自动根据预定义的表关系处理连接和聚合：
-
-```sql
-SELECT * FROM semantic_view(
-    tpch_rev_analysis,
-    DIMENSIONS order_date,
-    DIMENSIONS customer_name,
-    METRICS order_average_value
-);
-```
-
-语义视图查询具有以下优势：
-
-* **无需编写 JOIN 逻辑**：表连接由语义视图引擎根据外键定义自动完成。
-* **使用业务术语**：如 `customer_name`、`order_average_value` 代替物理列名，提升可读性。
-* **查询语法极大简化**：降低了非技术用户的使用门槛。
-* **指标定义集中管理**：确保了整个组织内度量计算的一致性。
-
-***
-
-## 管理语义视图
-
-### DROP SEMANTIC VIEW
-
-删除指定的语义视图。`IF EXISTS` 子句可防止在视图不存在时报错。
-
-**语法**：
-
-```sql
-DROP SEMANTIC VIEW IF EXISTS <视图名称>;
-```
-
-**示例**：
-
-```sql
-DROP SEMANTIC VIEW IF EXISTS tpch_rev_analysis;
-```
-
-### SHOW SEMANTIC VIEWS
-
-列出当前架构中所有可用的语义视图。
-
-**语法**：
-
-```sql
-SHOW SEMANTIC VIEWS;
--- 或指定架构
-SHOW SEMANTIC VIEWS IN <架构名>;
-```
-
-该命令返回语义视图所在的架构名称和视图名称，方便您查看当前环境中已创建的全部语义视图。
-
-### DESC EXTENDED
-
-查看指定语义视图的详细定义信息，包括逻辑表结构、维度元数据、指标定义、外键关系及索引信息。
-
-**语法**：
-
-```sql
-DESC EXTENDED <视图名称>;
-```
-
-**示例**：
-
-```sql
-DESC EXTENDED tpch_rev_analysis;
-```
-
-返回内容涵盖：逻辑表信息（物理表映射、主键和外键）、维度元数据（`isUnique`、`enumValues` 等属性）、指标定义（聚合表达式）以及索引信息（如 `BLOOM_FILTER`）。
-
-### 相关命令速查
-
-| 命令                             | 说明       |
-| ------------------------------ | -------- |
-| `CREATE SEMANTIC VIEW`         | 创建语义视图   |
-| `DROP SEMANTIC VIEW IF EXISTS` | 删除语义视图   |
-| `SHOW SEMANTIC VIEWS`          | 列出所有语义视图 |
-| `DESC EXTENDED`                | 查看语义视图详情 |
-| `semantic_view()`              | 查询语义视图   |
-
-***
-
-## 最佳实践
-
-**使用 DROP IF EXISTS 确保幂等性**：在创建语义视图之前，始终先执行 `DROP SEMANTIC VIEW IF EXISTS` 语句。这确保了您的脚本在任何环境中都可以重复执行，而不会因视图已存在而失败。
-
-```sql
-DROP SEMANTIC VIEW IF EXISTS tpch_rev_analysis;
-CREATE SEMANTIC VIEW tpch_rev_analysis
-    ...
-```
-
-**从小规模开始，逐步扩展**：建议从一个聚焦的分析场景开始（例如 3–5 张表的收入分析），验证维度和指标的定义准确性后，再逐步扩展到更多表和更复杂的业务逻辑。
-
-**使用有意义的业务术语命名**：为逻辑表、维度和指标选择与业务用户日常用语一致的名称。例如，使用 `customer_name` 而非 `c_name`，使用 `order_average_value` 而非 `avg_o_totalprice`。同时，善用 `WITH SYNONYMS` 和 `COMMENT` 增强语义视图的可发现性和可理解性。
-
-**合理定义维度元数据**：正确设置 `is_unique`、`is_time` 和 `enum_values` 等属性，帮助查询引擎优化执行计划，并为下游工具和用户提供更丰富的上下文信息。
-
-**注意逻辑表的定义顺序**：在 `TABLES` 子句中，被外键引用的逻辑表必须先于引用方定义。合理规划表的声明顺序可以避免创建时的引用错误。

-## 功能
-`SHOW CACHED STATUS`命令用于查看当前数据库中被缓存的表状态。需要注意的是，此命令仅能显示通过`CACHE`命令手动添加到缓存中的表，而无法显示系统自动缓存的表。
-
-## 语法
-```
-SHOW CACHED STATUS;
-```
-
-## 说明
-- 使用`SHOW CACHED STATUS`命令后，将列出所有正在被缓存的表及其相关信息。
-- 该命令不会显示因系统自动缓存机制而缓存的表，仅展示用户通过`CACHE`命令显式添加的表。
-
-## 示例
-```
--- 将tpch100g分区表part和nation添加到缓存中
-CACHE TABLE tpch100g.part, nation;
-
--- 查看当前缓存的表状态
-SHOW CACHED STATUS;
-```
-
-执行上述命令后，将显示类似于以下的结果：
-```
-+----------------+--------+-------+
-| Table           | Refs   | Cache |
-+----------------+--------+-------+
-| tpch100g.part  | 10     | YES   |
-| tpch100g.nation| 5      | YES   |

-## 常见问题
-
-Q1：如何查看表的详细信息（如表结构）？
-
-* 使用 `DESCRIBE` 或 `SHOW CREATE TABLE` 命令：
-  ```sql
-  DESCRIBE public.household_demographics;
-  SHOW CREATE TABLE public.household_demographics;
-  ```
-
-Q2：`SHOW COLUMNS` 是否支持过滤条件？
-
-* 不支持直接过滤，但可以通过查询 `INFORMATION_SCHEMA.COLUMNS` 实现：
-  ```sql
-  SELECT * FROM INFORMATION_SCHEMA.COLUMNS
-  WHERE TABLE_NAME = 'household_demographics' AND COLUMN_NAME LIKE 'name%';
-  ```

-## 功能描述
-本命令用于展示当前工作空间（workspace）内所有可用的函数，包括内置函数和外部函数。通过该命令，用户可以快速了解并选择所需的函数进行数据查询和处理。
-
-## 语法格式
-```SQL
-SHOW FUNCTIONS [ LIKE 'pattern' ]
-```
-
-## 参数说明
-- **LIKE 'pattern'**：该参数用于根据函数名称进行过滤，只展示与指定模式匹配的函数。支持使用 SQL 通配符，包括百分号（%）表示任意数量的字符，下划线（_）表示任意单个字符。
-
-## 使用示例
-
-1. 查看所有函数：
-   ```SQL
-   SHOW FUNCTIONS;
-   ```
-
-2. 根据函数名称部分关键词过滤结果，例如查找包含 "ABS" 的所有函数：
-   ```SQL
-   SHOW FUNCTIONS LIKE '%ABS%';
-   ```
-
-3. 查找特定的函数，例如查找名为 "SQRT" 的函数：
-   ```SQL
-   SHOW FUNCTIONS LIKE 'SQRT';
-   ```
-
-4. 使用通配符查找以 "DATE" 开头的所有函数：
-   ```SQL
-   SHOW FUNCTIONS LIKE 'DATE%';
-   ```
-
-5. 组合使用通配符进行更精确的查找，例如查找包含 "DATE" 并且以 "DIFF" 结尾的函数：
-   ```SQL
-   SHOW FUNCTIONS LIKE 'DATE%DIFF';
-   ```
-
-## 注意事项
-- 当不指定 LIKE 子句时，将展示所有可用的函数。
-- 使用通配符时，请确保它们紧跟在 LIKE 关键字之后，且前面不要有空格。
-- 在使用 SQL 通配符时，请注意避免使用过多的通配符，以免影响查询性能。
-
-通过以上示例和说明，用户可以更加方便地查找和使用所需的函数，从而提高数据处理和分析的效率。

-## 功能概述
-
-`SHOW SCHEMAS` 语句旨在展示当前工作空间（WORKSPACE）中所有模式（SCHEMA）的列表。用户可以通过灵活的过滤条件，根据特定的模式或条件来查看相关的 SCHEMA。此外，使用 `EXTENDED` 关键字可以获取每个 SCHEMA 的更多详细信息，例如其类型（MANAGED 或 EXTERNAL）。
-
-## 语法结构
-
-```Plain
-SHOW SCHEMAS [EXTENDED] [LIKE 'pattern' | WHERE expr];
-```
-
-## 参数详解
-
-* `LIKE pattern`: 此参数支持通过模式匹配来筛选输出结果。匹配方式不区分大小写，并支持使用 SQL 通配符 `%`（表示任意数量的字符）和 `_`（表示任意单个字符）。例如，`LIKE '%report%'` 会筛选出所有包含 "report" 字符串的 SCHEMA 名称。需要注意的是，`LIKE` 子句与 `WHERE` 子句互斥，不能同时使用。
-* `EXTENDED`: 当使用此关键字时，命令将返回包含额外信息的附加列，例如显示 SCHEMA 类型的 `type` 列，
-* `WHERE expr`: 此参数允许用户根据 `SHOW SCHEMAS` 命令展示的字段进行更细致的筛选，以便查找符合特定条件的 SCHEMA。
-
-## 使用示例
-
-以下是 `SHOW SCHEMAS` 命令的几个使用示例：
-
-1. 查看当前工作空间下的所有 SCHEMA：
-
-   ```SQL
-   SHOW SCHEMAS;
-   ```
-
-2. 获取所有 MANAGED 类型的 SCHEMA 及其详细信息：
-
-   ```SQL
-   SHOW SCHEMAS EXTENDED WHERE type='managed';
-   ```
-
-3. 若需要查找特定的 SCHEMA 名称，可以使用 `WHERE` 子句通过 SCHEMA 名称进行筛选：
-
-   ```SQL
-   SHOW SCHEMAS WHERE SCHEMA_NAME='your_schema_name';
-   ```
-
-## 权限要求
-
-为了执行 `SHOW SCHEMAS` 命令，用户必须具备对应 SCHEMA 的读取元数据（READ METADATA）权限。

-# 查看分享列表
-
-## 功能
-
-查看分享列表用于查询当前实例下所有的分享对象（share对象），帮助用户了解当前服务实例与其他服务实例之间的数据共享情况。
-
-## 语法
-
-```SQL
-SHOW SHARES  [LIKE 'pattern' | WHERE expr] [LIMIT num]
-```
-
-## 参数说明
-
-1. `LIKE pattern`：此选项为可选参数，用于按对象名称进行过滤。支持不区分大小写的模式匹配，并可使用SQL通配符`%`（表示任意数量的字符）和`_`（表示单个字符）。示例：`LIKE '%testing%'`。需要注意的是，此过滤器不支持与`WHERE`条件同时使用。
-
-2. `WHERE expr`：此选项为可选参数，支持用户根据`SHOW SHARES`命令显示的字段进行筛选。如：provider、provider\_instance、provider\_workspace、scope、to\_instance、kind
-
-## 返回说明
-
-* **provider**：share提供者的租户名，表示分享数据的来源。
-* **provider\_instance**：share提供者的服务实例名，表示分享数据的服务实例。
-* **provider\_workspace**：share所属的工作空间，表示share对象所在的工作空间。
-* **scope**：share的分享范围，当前仅支持PRIVATE——指定instance分享。表示share对象仅在指定的服务实例之间共享。
-* **to\_instance**：该share对象指定被分享至的服务实例名称，多个服务实例名称之间用英文逗号(,)分隔。表示当前share对象被分享给了哪些服务实例。
-* **kind**：share的类型，OUTBOUND为当前服务实例分享出的数据，INBOUND为其他服务实例分享至当前服务服务实例的数据。表示当前share对象是分享数据的来源还是接收数据的目的地。
-
-## 使用示例
-
-1. 查询当前服务实例下的所有分享对象：
-
-   ```SQL
-   SHOW SHARES ;
-   ```
-
-   假设返回结果如下：
-
-   ```
-   share_name |provider| provider_instance | provider_workspace | scope | to_instance | kind 
-   -----------------------+-------------------+--------------------+-------+---------------+-----
-   sample_data |my_tenant | my_service_instance | my_workspace       | PRIVATE | other_instance | OUTBOUND
-   another_demo |another_tenant | another_service_instance | another_workspace  | PRIVATE | my_service_instance | INBOUND
-   ```
-
-   在这个例子中，我们可以看到当前服务实例有两个分享对象。第一个对象是当前服务实例分享给名为other\_instance的服务实例的，分享范围为PRIVATE。第二个对象是来自另一个服务实例的分享，当前服务实例作为接收方。
-
-2. 使用**Like**参数过滤特定名称的分享对象：
-
-   ```SQL
-   SHOW SHARES LIKE '%data';
-   ```
-
-   假设返回结果如下：
-
-   ```
-   share_name |provider| provider_instance | provider_workspace | scope | to_instance | kind 
-   -----------------------+-------------------+--------------------+-------+---------------+-----
-   sample_data |my_tenant | my_service_instance | my_workspace       | PRIVATE | other_instance | OUTBOUND
-
-   ```
-
-3. 使用**WHERE**参数过滤输出结果，查询当前服务实例**分享出**的分享对象：
-
-   ```SQL
-   SHOW SHARES WHERE kind = 'OUTBOUND';
-   ```
-
-   假设返回结果如下：
-
-   ```
-   share_name | provider | provider_instance | provider_workspace | scope | to_instance | kind 
-   -----------------------+-------------------+--------------------+-------+---------------+-----
-   sample_outbound_share |my_tenant | my_service_instance | my_workspace| PRIVATE | other_instance | OUTBOUND
-   ```
-
-   可以看到，当前服务实例分享给了名为other\_instance的服务实例一个名为sample\_outbount\_share 的分享对象。
-
-4. 使用**WHERE**参数过滤输出结果，查询当前服务实例**被分享**的分享对象：
-
-```SQL
-   SHOW SHARES WHERE kind = 'INBOUND';
-```
-
-&#x20;     假设返回结果如下：
-
-```
-share_name | provider | provider_instance | provider_workspace | scope | to_instance | kind 
------------------------+-------------------+--------------------+-------+---------------+-----
-sample_inbound_share |other_tenant | other_instance | demo_workspace| PRIVATE | current_instance | INBOUND
-```
-
-可以看到，当前服务实例被分享了名为sample\_inbound\_share 的，来自于实例名称为other\_instance分享对象。
-
-通过以上示例，您可以更轻松地查看和管理当前服务实例下的所有分享对象。

-| **SYNONYM**      | `synonym_name`, `create_time`, `target_type`, `target_name`                                                                                          |
-| **PIPE**         | `pipe_name`, `pipe_kind`, `status`, `copy_statement`                                                                                                |
-| **SCHEMA**       | `schema_name`, `type`                                                                                                |
-
-  ```sql
-  SHOW TABLES WHERE table_name=base_a_dt;
-  ```
-
-4. 结果限制
-- **`LIMIT <num>`**（可选）
-  限制返回结果数量
-  ```sql
-  SHOW TABLES LIMIT 10
-  ```
-
-5. 特殊语法形式
-索引/列的 FROM 语法：对于索引和列对象，支持使用 `FROM` 替代 `IN TABLE`：
-```sql
-SHOW INDEXES FROM customers       -- 等效于 SHOW INDEXES IN TABLE customers
-SHOW COLUMNS FROM order_details   -- 等效于 SHOW COLUMNS IN TABLE order_details
-```
-
-## 注意事项
-1. CONNECTION 和 SHARE 不支持作用域限定
-2. 模式匹配区分大小写
-3. `WHERE` 子句支持标准 SQL 表达式语法
-4. 返回结果默认按对象名称排序
-
-
-## LIKE子句的使用示例
-
-```SQL
--- 查找名称中包含'taxi'的所有表
-SHOW TABLES LIKE '%taxi%';
-
--- 查找名称以'yellow'开头的所有表
-SHOW TABLES LIKE 'yellow%';
-
--- 查找名称中第二个字符为'a'的所有schema
-SHOW SCHEMAS LIKE '_a%';
-```
-
-## WHERE子句的使用示例
-
-```SQL
--- 查找所有不是视图的表
-SHOW TABLES WHERE is_view=false;
-
--- 查找所有外部表
-SHOW TABLES WHERE is_external=true;
-
--- 查找特定schema中的所有表
-SHOW TABLES WHERE schema_name='mcp_demo';
-
--- 使用多个条件进行过滤
-SHOW TABLES WHERE is_view=false AND table_name LIKE '%taxi%';
-
--- 查找特定连接的卷
-SHOW VOLUMES WHERE connection='xxx.storage_connection';
-
--- 查找外部卷
-SHOW VOLUMES WHERE external=true;
-```
-
-## 使用建议
-
-1. 当只需要按对象名称过滤时，使用LIKE子句更为简洁
-2. 当需要基于对象的属性或特性进行筛选时，使用WHERE子句更为灵活
-3. 对于不支持WHERE子句的对象类型，只能使用LIKE子句进行名称过滤
-4. WHERE子句支持更复杂的过滤条件，包括逻辑运算符的组合
-
-请注意，云器 Lakehouse 的 SHOW 命令功能与标准 SQL 中的 SHOW 命令相似，但有其特定的语法和支持范围。

-:-: ![](.topwrite/assets/image_1734329148588.png =700)
-
-#####   02、开始采集    
-
-开始进行采集，等待采集完成后，检查采集到的数据是否符合预期。要提前留意本地采集和云采集在导出数据上的不同。因为方式二支持导出到 MySQL，而本地采集不支持，所以选择了云采集方式。
-
-:-: ![](.topwrite/assets/image_1734329171687.png =700)
-
-检查采集到的数据是否符合预期：    
-首先，需要对采集到的数据进行全面的审查和分析。这包括数据的准确性、完整性和一致性。准确性是指数据是否准确无误地反映了实际情况；完整性是指数据是否涵盖了所有预期的信息；一致性是指数据在不同来源或不同时间点是否保持一致。    
-接着，要将采集到的数据与预期的标准和规范进行比对。例如，数据的格式是否符合要求，数据的取值范围是否在合理的范围内，数据的逻辑关系是否正确等。   
- 然后，还需要检查数据的合理性。通过对数据的观察，判断数据是否存在异常或不合理的波动。
-
-:-: ![](.topwrite/assets/image_1734329188223.png =700)
-
-#####   03、数据导出    
-
-导出数据为Excel文件。八爪鱼采集到的数据，支持自动导出数据到本地文件，文件格式包括Excel、CSV、html、json、Xml，注意团队版和企业版才支持该功能，如需自动导出到本地文件，请升级到账号到对应套餐版本。

-# 自动合并小文件功能
-
-在数据写入过程中，Lakehouse 提供了一项自动合并小文件的功能，旨在提升存储效率和查询性能。这项功能对于处理由高频写入操作产生的大量小文件尤其有效，因为这些小文件在查询时可能会引起频繁的I/O操作，进而影响整体性能。需要注意的是，启用此功能可能会导致写入速度变慢，因为合并操作需要额外的时间来处理。
-
-> 虽然 Lakehouse 后台默认会不定时自动执行文件合并，但在频繁更新或需要精细控制合并频率的场景中，用户可以通过手动调用该命令来满足特定业务需求。该命令支持异步和同步两种执行模式，为不同场景提供灵活的优化方案。
-
-**功能优势**：
-
-* **减少I/O操作**：合并小文件可以减少查询过程中的I/O操作，从而加快数据访问速度。
-* **自动触发**：在数据插入时，合并操作会自动执行，无需用户进行额外的手动操作。
-# 注意事项
-- 该功能只能在**通用型（GENERAL PURPOSE VIRTUAL CLUSTER）计算集群**上运行，在分析型计算集群上该功能不会生效。
-# 执行DML语句时触发小文件合并
-添加如下设置，选中后和 DML 语句一起执行会触发小文件合并。
-`SET cz.sql.compaction.after.commit = true;`
-
-
-## 使用场景
-
-* **高频写入**：在需要频繁写入数据的场景下，如动态表刷新，建议开启此功能。高频写入往往会生成大量小文件，自动合并可以有效地管理这些文件。
-
-## 使用案例
-
-假设您有一个名为`test_sql_compaction`的表，用于存储分区数据。
-
-```SQL
-CREATE TABLE test_sql_compaction (
-    id BIGINT,
-    name STRING
-) PARTITIONED BY (ds STRING);
-```
-
-在未启用自动合并功能前，每次插入操作可能会生成多个小文件。例如，插入 10 条记录：
-
-```SQL
--- 插入10条记录
-INSERT INTO test_sql_compaction PARTITION (ds ='1') VALUES(1, 'a');
--- 重复此INSERT操作共10次
-```
-
-插入后，您可以查看生成的文件数量：
-
-```SQL
-SHOW PARTITIONS EXTENDED test_sql_compaction;
-```
-
-再次插入数据：
-
-```SQL
-SET cz.sql.compaction.after.commit = true;
-INSERT INTO test_sql_compaction PARTITION (ds ='1') VALUES(1, 'a');
-```
-
-合并后，再次查看文件数量，您会发现小文件已被合并：
-
-```SQL
-SHOW PARTITIONS EXTENDED test_sql_compaction;
-```
-# 使用OPTIMIZE命令触发小文件合并
-## 概述
-`OPTIMIZE` 是 Lakehouse 提供的一个异步文件优化命令，用于合并小文件、优化存储布局，提升查询性能。该命令‌**仅支持在 GP 型计算集群运行**‌，执行后立即返回任务ID，实际优化操作在后台异步执行。
-## 语法
-```SQL
-OPTIMIZE table_name
-[WHERE predicate]  -- 可选分区过滤条件
-[OPTIONS ('key' = 'value')]  -- 可选配置参数
-```
-## 参数说明
-1. table_name（必选）
-* 需要优化的目标表名称，格式为 `[schema_name.]table_name`
-2. WHERE predicate（可选）
-* 分区过滤条件，必须包含‌**完整的分区列匹配条件**‌
-* 支持格式：`partition_column = 'value'` 或复合分区 `dt='2023-01-01' AND region='us'`
-* OPTIONS:Lakehouse保留参数
-## 使用案例
-假设您有一个名为`test_sql_compaction`的表，用于存储分区数据。
-```SQL
-DROP TABLE test_sql_compaction;
-CREATE TABLE test_sql_compaction (
-    id BIGINT,
-    name STRING
-) PARTITIONED BY (ds STRING);
-```
-在未启用自动合并功能前，每次插入操作可能会生成多个小文件。例如，插入 10 条记录：
-```SQL
--- 插入10条记录
-INSERT INTO test_sql_compaction PARTITION (ds ='1') VALUES(1, 'a');
--- 重复此INSERT操作共10次
-```
-插入后，您可以查看生成的文件数量：
-```SQL
-SHOW PARTITIONS EXTENDED test_sql_compaction;
-```
-执行合并小文件命令
-```SQL
-OPTIMIZE  test_sql_compaction;
-```
-合并后，再次查看文件数量，您会发现小文件已被合并：
-```SQL
-SHOW PARTITIONS EXTENDED test_sql_compaction;
-```

-# Spark Connector概述
-
-Lakehouse Connector for Spark 允许使用 Lakehouse 作为 Apache Spark 数据源，类似于其他数据源（PostgreSQL、HDFS、S3 等）。
-
-![](.topwrite/assets/image_1726132702601.png)
-
-## Lakehouse和Spark之间的交互
-
-该连接器支持 Lakehouse和 Spark 集群之间的双向数据移动。使用连接器，您可以执行以下操作:
-
-* 读取Lakehouse 中的表转化为Spark DataFrame
-* 将 Spark DataFrame 的数据写入 Lakehouse的表中。
-
-![](.topwrite/assets/image_1726132853684.png)
-
-数据传输过程
-
-两个系统之间的数据传输通过连接器自动创建和管理的Lakehouse volume实现.
-
-* 连接到Lakehouse，执行查询时会将数据加载到临时volume中，connector使用该volume来存储数据。
-* 写入Lakehouse，通过调用Lakehouse的bulkload批量写入sdk写入。

-```Scala
-bin/spark-shell --jars ./spark_conenctor/spark-clickzetta-1.0.0-SNAPSHOT-jar-with-dependencies.jar
-import org.apache.spark.sql.functions.col
-import com.clickzetta.spark.clickzetta.ClickzettaOptions
-val readDf = spark.read.format("clickzetta").option(ClickzettaOptions.CZ_ENDPOINT, "lakehouse_url").option(ClickzettaOptions.CZ_USERNAME, "user").option(ClickzettaOptions.CZ_PASSWORD, "password").option(ClickzettaOptions.CZ_WORKSPACE, "quikc_start").option(ClickzettaOptions.CZ_VIRTUAL_CLUSTER, "default").option(ClickzettaOptions.CZ_SCHEMA, "public").option(ClickzettaOptions.CZ_TABLE, "birds_test").load()
-readDf.show()
-```
-
-2. 使用spark-sql命令行连接Lakehouse
-
-```Scala
-bin/spark-sql --jars ./jars/spark-clickzetta-1.0.0-SNAPSHOT-jar-with-dependencies.jar
-CREATE TABLE lakehouse_table
-USING clickzetta
-OPTIONS (
-    endpoint 'lakehouse_url',
-    username 'user',
-    password 'password',
-    workspace 'quikc_start',
-    virtualCluster 'default',
-    schema 'public',
-    table 'birds_test'
-);
-```
-
-3. 使用pyspark命令行连接Lakehouse
-
-```Scala
-bin/pyspark --jars ./jars/spark-clickzetta-1.0.0-SNAPSHOT-jar-with-dependencies.jar
-df=spark.read.format("clickzetta").option("endpoint", "demo.cn-shanghai-alicloud.api.clickzetta.com").option("username", "user").option("password", "password").option("workspace","quick_start").option("virtualCluster", "default").option("schema", "public")option("table","birds_test").load()
-df.show()
-```
-
-## Lakehouse Spark Connector使用限制
-
-* 不支持pk表写入
-* 必须全字段写入, 不支持部分字段写入
-
-# 使用Spark Connector实践案例
-
-## 使用Spark写入Lakehouse数据
-
-**概述**
-
-不同平台之间的无缝数据传输对于有效的数据管理和分析至关重要。我们帮助许多客户解决的一个常见场景是使用Spark处理完数据写入到Lakehouse中，BI报表连接Lakehouse查询。
-
-我们编写一个Spark程序，并在Spark环境中运行它，使用Lakehouse提供的Connector将数据写入到Lakehouse中
-
-**环境要求**
-
-* 具备Spark编程能力。可以参考[使用 IntelliJ IDEA开发Spark](https://blog.csdn.net/boling_cavalry/article/details/87510822)
-
-* 本次案例使用的数据是spark github上电影评分数据集，您可以通过此[链接](https://github.com/apache/spark/blob/master/data/mllib/sample_movielens_data.txt)点击下载按钮下载
-
-* 在Lakehouse中创建表
-
-  * ```SQL
-    create table sample_movie_data(user_id int,movie_id int,rating float);
-    ```
-
-* 下载Lakehouse提供的Spark Connector包（目前由Lakehouse支持提供下载包），下载完成将jar打入到本地maven库中，方便在maven项目中引用和打包
-
-  * ```SQL
-    mvn install:install-file -Dfile=./Downloads/spark-clickzetta-1.0.0-SNAPSHOT-jar-with-dependencies.jar -DgroupId=com.clickzetta -DartifactId=spark-clickzetta -Dversion=1.0.0-SNAPSHOT -Dpackaging=jar
-    ```
-
-* 修改pom.xml文件，添加如下依赖
-
-```XML

-
-```sql
--- 为表设置属性
-ALTER TABLE [schema_name.]table_name SET PROPERTIES ('property_key1'='property_value1' [, 'property_key2'='property_value2' ...]);
--- 为schema设置属性
-ALTER SCHEMA schema_name SET PROPERTIES ('property_key1'='property_value1' [, 'property_key2'='property_value2' ...]);
--- 为Workspace设置属性
-ALTER WORKSPACE workspace_name SET PROPERTIES ('property_key1'='property_value1' [, 'property_key2'='property_value2' ...]);
-```
-
-**参数说明**
-
-| 参数              | 说明                              |
-| --------------- | ------------------------------- |
-| schema\_name    | 可选参数，指定表所在的模式。若省略，系统使用当前会话的默认模式 |
-| table\_name     | 要设置属性的表名                        |
-| schema\_name    | 要设置属性的模式名                       |
-| workspace\_name | 要设置属性的工作空间名                     |
-| property\_key   | 属性键名，需用单引号括起                    |
-| property\_value | 属性值，需用单引号括起                     |
-
-**使用示例**
-
-```sql
--- 为表设置压缩和自动刷新属性
-ALTER TABLE sales_records SET PROPERTIES ('compression'='zstd', 'auto_refresh'='true');
--- 为模式设置数据保留期属性
-ALTER SCHEMA reporting SET PROPERTIES ('data_retention_days'='90');
--- 为Workspace设置属性
-ALTER WORKSPACE analytics_ws SET PROPERTIES ('aa'='bb');
-```
-
-### 表支持的参数
-
-以下表格列出了系统属性及其描述和取值范围：
-
-| 参数名称                              | 描述                                                                                                                                                                                                                       | 取值范围                                                                      |
-| --------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------- |
-| data\_lifecycle                   | 数据生命周期                                                                                                                                                                                                                   | 大于0的正整数值，取值为-1代表未开启生命周期                                                   |
-| data\_retention\_days             | 设置Time Travel保留期限，Time Travel保留期限决定了您可以访问多久以前的数据，包括使用 UNDROP、TABLE STREAM、RESTORE 访问历史数据和恢复历史数据。                                                                                                                            | 您可以为每个表设置不同的数据保留周期，以满足不同的业务需求。num 的设置范围为 0-90，Lakehouse 将单独对 Time Travel 收取存储费用。 |
-| cz.storage.write.max.string.bytes | `STRING` 类型用于存储长度大于或等于 0 的字符序列，最大可支持 16MB 的文本数据。在批量或实时导入数据时，系统会对字段长度进行校验。若导入数据超出 16MB，可通过修改表属性调整字符串长度限制，例如将 `STRING` 长度设置为 32MB：`ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.string.bytes"="33554432");` | 大于0的整数                                                                    |
-| cz.storage.write.max.binary.bytes | `binary` 类型用于存储长度最大可支持 16MB 的数据。在批量或实时导入数据时，系统会对字段长度进行校验。若导入数据超出 16MB，可通过修改表属性调整binary长度限制，例如将 `binary` 长度设置为 32MB：`ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.binary.bytes"="33554432");`              | 大于0的整数                                                                    |
-| cz.storage.write.max.json.bytes   | `json` 类型用于存储长度大于或等于 0 的字符序列，最大可支持 16MB 的文本数据。在批量或实时导入数据时，系统会对字段长度进行校验。若导入数据超出 16MB，可通过修改表属性调整json字符串长度限制，例如将 `json` 长度设置为 32MB：`ALTER TABLE table_name SET PROPERTIES("cz.storage.write.max.json.bytes"="33554432");`   | 大于0的整数                                                                    |
-
-### UNSET PROPERTIES
-
-**命令用途**
-
-`UNSET PROPERTIES` 命令用于移除数据对象上已设置的属性。它让您能够清除不再需要的自定义属性，将对象恢复到系统默认配置状态。
-
-**语法格式**
-
-```sql
--- 移除表的属性
-ALTER TABLE [schema_name.]table_name UNSET PROPERTIES (property_key1 [, property_key2 ...]);
--- 移除模式的属性
-ALTER SCHEMA schema_name UNSET PROPERTIES (property_key1 [, property_key2 ...]);
--- 移除Workspace的属性
-ALTER WORKSPACE workspace_name UNSET PROPERTIES (property_key1 [, property_key2 ...]);
-```
-
-**参数说明**
-
-| 参数              | 说明                              |
-| --------------- | ------------------------------- |
-| schema\_name    | 可选参数，指定表所在的模式。若省略，系统使用当前会话的默认模式 |
-| table\_name     | 要移除属性的表名                        |
-| schema\_name    | 要移除属性的模式名                       |
-| workspace\_name | 要移除属性的工作空间名                     |
-| property\_key   | 要移除的属性键名                        |
-
-**使用示例**
-
-```sql
--- a) 移除表的单个属性
-ALTER TABLE sales_records UNSET PROPERTIES ('xxx');
--- b) 同时移除表的多个属性
-ALTER TABLE customer_feedback UNSET PROPERTIES ('auto_refresh', 'xxxx');
--- c) 移除模式的属性
-ALTER SCHEMA reporting_data UNSET PROPERTIES ('default_table_format');
--- d) 移除Workspace的属性
-ALTER WORKSPACE data_science UNSET PROPERTIES ('xxx');
-```
-
-## SHOW PROPERTIES
-
-**命令用途**
-
-`SHOW PROPERTIES` 命令用于查看数据对象当前设置的所有属性。它帮助您了解对象的配置状态，便于属性管理和问题排查。
-
-**语法格式**
-
-```sql
--- 查看表的属性
-SHOW PROPERTIES IN TABLE [schema_name.]table_name;
--- 查看模式的属性
-SHOW PROPERTIES IN SCHEMA schema_name;
--- 查看Workspace的属性
-SHOW PROPERTIES IN WORKSPACE workspace_name;
-```
-
-**参数说明**
-
-| 参数              | 说明                              |
-| --------------- | ------------------------------- |
-| schema\_name    | 可选参数，指定表所在的模式。若省略，系统使用当前会话的默认模式 |
-| table\_name     | 要查看属性的表名                        |
-| schema\_name    | 要查看属性的模式名                       |
-| workspace\_name | 要查看属性的工作空间名                     |
-
-**使用示例**
-
-```sql
--- 查看表的所有属性
-SHOW PROPERTIES IN TABLE sales_data;
--- 查看特定模式中表的属性
-SHOW PROPERTIES IN TABLE analytics.customer_metrics;
--- 查看模式的所有属性
-SHOW PROPERTIES IN SCHEMA reporting;
--- 查看Workspace的所有属性
-SHOW PROPERTIES IN WORKSPACE data_science;
-```
-
-**输出说明**
-
-`SHOW PROPERTIES` 命令的输出结果是一个包含键值对的列表，如下所示：
-
-```
-+---------------+---------------+
-| property_key  | property_value|
-+---------------+---------------+
-| compression   | zstd          |
-| auto_refresh  | true          |
-+---------------+---------------+
-```
-
-**支持的对象类型**
-
-当前，Lakehouse 支持为以下三种主要对象类型管理属性：
-
-1. **Workspace 属性**：作用于整个工作空间，影响其中的所有模式和表。通常包括资源限制、安全设置等全局配置。
-2. **Schema 属性**：作用于特定模式，影响该模式下的所有表。常用于设置模式级别的默认行为。
-3. **Table 属性**：作用于特定表，仅影响该表的行为和性能特性。这是最细粒度的属性设置。
-
-### 执行行为说明
-
-使用属性管理命令时，应注意以下行为特性：
-
-1. **静默处理**：如果尝试移除不存在的属性，命令会静默成功，不会抛出错误。
-2. **批量操作**：可在一个命令中设置或移除多个属性，提高操作效率。
-3. **权限要求**：需要对应对象的 `ALTER` 权限才能修改其属性。
-4. **Workspace 属性生效时间**：Workspace 级别的属性修改通常在约 1 分钟后生效。
-
-### 应用场景
-
-**环境迁移与配置管理**
-
-在开发、测试和生产环境之间迁移数据应用时，属性管理非常重要。
-
-```sql
--- 生产环境设置更严格的属性
-ALTER TABLE customer_data SET PROPERTIES ('encryption'='true', 'backup_schedule'='daily');
--- 移除仅适用于测试环境的属性
-ALTER TABLE customer_data UNSET PROPERTIES (debug_mode, test_flag);
-```
-
-**清理过时配置**
-
-```sql
--- 查找具有过时属性的表
-SHOW PROPERTIES IN TABLE legacy_system_data;
--- 移除过时的兼容性属性
-ALTER TABLE legacy_system_data UNSET PROPERTIES (compatibility_mode, legacy_format);
-```
-
-**属性变更验证**
-
-执行属性变更后，可通过以下方式验证操作是否成功：
-
-```sql
--- 使用SHOW PROPERTIES命令直接查看
-SHOW PROPERTIES IN TABLE modified_table;
--- 或使用DESC命令查看详细信息
-DESC TABLE EXTENDED modified_table;
-```
-
-## 会话参数

-## 会话参数使用方法
-
-1. 在 Lakehouse Studio 编辑器中，您需要选中要执行的查询并执行它们。例如，要设置`query_tag`参数并执行一个简单的查询，请参考以下步骤：
-   执行以下命令设置`query_tag`参数：
-
-```sql
-set query_tag='test';
-select 1+2;
-```
-
-2. 如果在客户端或者 JDBC 运行会话参数，则会在整个会话期间生效。
-
-```sql
-set query_tag='test';
-select 1+2;
-```
-
-上面的query\_tag仍然会生效
-
-```
-select 1+4;
-```
-
-**Python SDK 设置参数**
-在 JDBC 中通过 SET 命令设置的 SQL hints 可以通过 `parameters` 参数传递。以下是一个修改时区示例：
-
-```python
-from clickzetta import connect
-# 建立连接
-
-conn = connect(username='',
-               password='',
-               service='region_id.api.clickzetta.com',
-               instance='demo_instance',
-               workspace='demo_workspace',
-               schema='public',
-               vcluster='default')
-my_param = {
-    'hints': {
-        'cz.sql.timezone': 'UTC+00'
-    }
-}
-cursor = conn.cursor()
-cursor.execute("select current_timestamp();",my_param)
-
-# 获取查询结果
-results = cursor.fetchall()
-for row in results:
-        print(row)
-# 关闭连接
-cursor.close()
-conn.close()
-```
-
-## 会话参数说明
-
-### cz.sql.group.by.having.use.alias.first
-
-此参数指定group by和having语句是否优先使用列的别名，而非从From语句里寻找列的名字。例如，考虑以下查询：
-
-```sql
-select count(*) from (select col1 as c1 from table1) t group by c1;
-```
-
-如果启用此参数，查询将使用别名`c1`进行分组。否则，将会报错找不到c1。
-
-### query\_tag
-
-设置query\_tag后，会话中的查询作业历史将自动在作业历史的query\_tag字段中添加自定义标签内容。可以通过set query\_tag命令方式设置，也可以在jdbc URL中设置query\_tag。例如：
-
-```sql
-set query_tag='aa';
-select 1;
-```
-
-* 在jdbc url中添加query\_tag,这样提交的每条SQL都会带上query\_tag用来标识来源，可以在页面中进行过滤
-  ```
-  jdbc:clickzetta://demo_instance.cn-shanghai-alicloud.api.clickzetta.com/default?schema=public&query_tag=test
-  ```
-* python代码中设置query\_tag
-  ```python
-  # 建立连接
-  conn = connect(username='',
-                 password='',
-                 service='cn-shanghai-alicloud.api.clickzetta.com',
-                 instance='demo_instance',
-                 workspace='',
-                 schema='public',
-                 vcluster='default')
-  # 执行 SQL
-  cursor = conn.cursor()
-  my_param["hints"]["query_tag"] ="test"
-  cursor.execute('select 1;', parameters=my_param)
-  ```
-
-在 Studio 的作业历史中过滤，当前只支持精确匹配。
-
-![Image](.topwrite/assets/image_1702889439834.png)
-
-借助query\_tag参数，您可以对作业进行分类和检索。在Lakehouse 的information\_schema查询过滤作业：
-
-```sql
-select * from information_schema.job_history where query_tag='aa';
-```
-
-在show jobs中可以过滤：
-
-```sql
-show jobs where query_tag='aa' limit 100 ;
-```
-
-desc jobs中也可以展示设置的query tag
-
-```sql
-desc job '202311281613333434l4r2v3c8ni0';
-```
-
-![Image](.topwrite/assets/image_1702889456850.png)
-
-### cz.sql.double.quoted.identifiers
-
-* 在 SQL 的 ANSI/ISO 标准中，双引号中的标识符（分隔标识符）允许用户可以写特殊字符或者关键字。Lakehouse也可以兼容此行为。
-* 开启后双引号为分隔符标识符，SET cz.sql.double.quoted.identifiers=true 当前只支持会话级别开启。**需要特别注意的是，如果开启双引号为分隔符标识符后，Lakehouse 将不再把双引号括起来的数据认为是一个字符串类型。**
-
-### cz.sql.cast.mode
-
-* 开启cast strict模式后，显式转换无法转换的类型会报错，可以使用try\_cast函数
-* 隐式转换行为无法转换的会报错。案例：比如 `select case when true then 'lakehouse' else nvl(null,-99) end;` 此案例中我们想返回 lakehouse 字符串。但是由于SQL写的不规范，nvl中是一个int类型，then中是一个string类型。按照类型优先级转换规则推测会认为整体应该返回一个int类型。上面是一个true会直接进入到true的输出中，由于`lakehouse`是一个字符串转换成int，系统默认行为会直接走try\_cast，lakehouse转换成int时则会变成null，会导致一些结果超出预期。如果严格模式，系统则不会自动走try\_cast会将异常抛出，告知用户这个SQL不是规范行为，如果确认逻辑正确，在开启ansi模式下添加try\_cast函数
-
-```
-select case when true then cast('lakehouse' as int) else nvl(null,-99) end;
-select case when true then try_cast('123' as int) else nvl(null,-99) end;
-```
-
-### schedule\_job\_queue\_priority
-
-**作业优先级**
-用户提交的SQL作业会附带一个优先级设置，该设置决定了作业在队列中的执行顺序。系统会根据这些设置来确定哪些作业应该优先执行，并优先将它们下发到虚拟集群（VCLUSTER）进行处理。对于GP和AP类型的VCLUSTER，优先级设置决定了哪个作业首先被下发到VCLUSTER。在计算集群中有大量作业排队等待处理时，设置作业优先级尤为有效。
-
-**作业优先级划分**
-
-* 定义：作业优先级是一个数值，用于标识作业的执行顺序。
-* 对应数字：数值范围从0到9，数值越大，表示优先级越高。
-
-**作业优先级设置**
-
-* SQL支持：用户可以在当前临时会话中修改作业的优先级，以便在提交作业时指定优先级。
-* 设置语法：使用以下命令来设置作业优先级：
-
-```sql
-SET schedule_job_queue_priority = {优先级数值};
-```
-
-* 其中，{优先级数值}是一个介于0到9之间的整数。
-
-**案例**
-
-```scala
-set schedule_job_queue_priority=2;
-select current_timestamp();
-```
-
-以下是针对您提到的几个参数的案例：
-
-### cz.sql.string.literal.escape.mode
-
-**参数说明**：此参数用于控制字符串字面量的转义字符。默认使用反斜线（`\`）作为转义字符。
-
-**案例**：
-
-* 默认模式（backslash）：
-  ```sql
-  SELECT 'Hello \n World!' AS res;
-  +---------+
-  |   res   |
-  +---------+
-  | Hello 
-   World!   |
-  +---------+
-  SELECT 'It''s a beautiful day' as res;
-  +---------------------+
-  |         res         |
-  +---------------------+
-  | Its a beautiful day |
-  +---------------------+
-  ```
-
-* 引号模式(quote)：
-
-  ```sql
-  SET cz.sql.string.literal.escape.mode = QUOTE;
-  SELECT 'It''s a beautiful day';
-  +----------------------+
-  |         res          |
-  +----------------------+
-  | It's a beautiful day |
-  +----------------------+
-  ```
-
-  这个查询将返回字符串 `It's a beautiful day`。注意，这里使用了两个单引号 `''` 来表示一个单独的单引号。
-
-
-* **同时支持引号和反斜线模式（quote_backslash）**：
-  ```sql
-  SET cz.sql.string.literal.escape.mode = quote_backslash;
-  SELECT 'Hello \n World!' AS res,'It''s a beautiful day' as res2;
-  +---------+---------------------+
-  |   res   |        res2         |
-  +---------+---------------------+
-  | Hello 
-   World! | Its a beautiful day |
-  +---------+---------------------+
-
-  ```
-  在这个例子中，既可以使用反斜线转义特殊字符，也可以使用双引号来包含引号。
-
-### cz.sql.arithmetic.mode
-
-**参数说明**：此参数控制算术运算出错时是否抛出异常。默认为 `tolerant`，即不抛出异常。
-
-**案例**：
-
-* **tolerant模式（默认）**：
-  ```sql
-  SELECT 2/0 res;
-  +------+
-  | res  |
-  +------+
-  | null |
-  +------+
-
-  ```
-  在这个例子中，除以 0 返回一个 `NULL` 或者一个溢出的值，而不是抛出异常。
-
-* **strict模式**：
-  ```sql
-  SET cz.sql.arithmetic.mode = strict;
-  SELECT 2/0 res;
-  CZLH-22012:arithmetic divide by zero. Detail  taskId 0, vertex name=stg0, vertexId=2024121311314772461pl5i9617d2_94570-V0 (state=,code=0)
-  ```
-  在这个例子中，将会抛出一个异常，因为 `strict` 模式下不允许算术运算除以 0。
-
-### cz.sql.timezone
-
-**参数说明**：此参数用于设置 SQL 会话的[时区](https://data.iana.org/time-zones/tzdb-2021a/zone1970.tab)。
-
-**案例**：
-
-* **设置时区为UTC+08**：
-  ```sql
-  SET cz.sql.timezone = Asia/Shanghai;
-  SELECT NOW() AS res;
-  +---------------------------+
-  |            res            |
-  +---------------------------+
-  | 2024-12-13 07:43:28.275429|
-  +---------------------------+
-  ```
-
-* 在这个例子中，`NOW()` 函数将返回当前的日期和时间，根据 `Asia/Shanghai` 时区（UTC+08）进行调整。
-
-* **设置时区为UTC**：
-  ```sql
-  SET cz.sql.timezone = UTC;
-  SELECT NOW() AS res_utc;
-  +----------------------------+
-  |          res_utc           |
-  +----------------------------+
-  | 2024-12-13 07:43:46.791785 |
-  +----------------------------+
-  ```
-  在这个例子中，`NOW()` 函数将返回当前的日期和时间，根据UTC时区进行调整。
-
-### cz.sql.remote.udf.lookup.policy
-
-**参数说明**：动态切换 UDF 与内置函数的解析优先级。
-
-**案例**：
-
-默认行为，使用UDF时必须带SCHEMA前缀
-
-```sql
---创建函数
-CREATE FUNCTION public.lower()
-RETURNS STRING
-AS 'Hello World!';
---使用函数，必须写SCHEMA否则会报错函数找不到
-SELECT public.lower();
--- 策略1：优先调用内置函数，可以不用写SCHEMA。如果和内置函数同名优先使用内置函数
-SET cz.sql.remote.udf.lookup.policy = builtin_first;
-SELECT lower();
--- 策略2：优先调用UDF（适配MC/Spark作业场景）。如果和内置函数同名优先使用udf
-SET cz.sql.remote.udf.lookup.policy = udf_first;
-SELECT lower();
-```
-
-### cz.sql.translation.mode 【预览发布】本功能当前处于公开预览发布阶段。
-
-**参数说明**：通过设置此参数，Lakehouse 可将指定 SQL 方言的语法自动转换为原生可执行语法，实现多方言兼容查询。本功能基于改进版 [SQLGlot](https://github.com/clickzetta/sqlglot-clickzetta) 实现，支持将常见数据库语法透明转换为 Lakehouse 原生语法，降低业务迁移成本。需要注意的是，并非支持全部的语法转换，只是部分语法可以转换。目前支持 PostgreSQL、MySQL、Doris、Hive、Presto。
-
-**案例**：
-
-设置Doris转化
-
-```sql
---设置Doris转化
-set cz.sql.translation.mode=doris;
-SELECT DATE_ADD(CURRENT_TIMESTAMP(), INTERVAL 1 HOUR);
-```
-
-DATE\_FORMAT 和 AES\_DECRYPT 函数需要指定 cz.sql.compatible.target 引擎兼容模式，以设置兼容 MySQL 或 PostgreSQL 的原始语义。
-
-```sql
---兼容 mysql DATE_FORMAT 函数的原生语义
-set cz.sql.compatible.target=mysql;
-select DATE_FORMAT(CURRENT_DATE(), '%x-%v %a %W');
-
---兼容 pg DATE_FORMAT 函数的原生语义
-set cz.sql.compatible.target=pg;
-SELECT DATE_FORMAT(CURRENT_TIMESTAMP(), 'yyyy-"Q"Q')
-
---兼容 mysql AES_DECRYPT 函数的原生语义
-set cz.sql.compatible.target=mysql;
-SELECT CAST(AES_DECRYPT(UNBASE64('fOltPBoMXnbhu54SSxaaAQ=='), 'namePURPMEF4uI2mQSbrWOhpAvu6OGbE4U') AS STRING);
-```
-
-### cz.sql.type.conversion
-
-**默认值**：无
-**取值为 hive 时**：兼容 Hive 的类型转换规则。
-
-用于兼容 Hive 的类型转换。由于 Lakehouse 和 Hive 的默认类型转换规则存在差异，设置此参数可使类型转换逻辑与 Hive 保持一致。详细的类型转换优先级规则可参考[类型转化](datatype-conversion.md)。
-
-### cz.sql.function.from.unixtime.trim.to.second
-
-**默认值**：false
-
-控制 `FROM_UNIXTIME` 函数的精度处理。启用时，函数返回值将精度截断到秒级，与 Hive 的行为保持一致。
-
-### cz.sql.time.parser.strict.mode
-
-**默认值**：false
-
-启用时间解析的严格模式。若时间格式与指定的格式模式不匹配，系统将抛出错误；禁用时则返回 `null`。
-
-**示例**：
-
-```sql
-SET cz.sql.time.parser.strict.mode=true;
-SELECT TO_TIMESTAMP('2025-08-01','yyyy-MM-dd HH');
-执行结果: ❌ 错误发生
-
-SET cz.sql.time.parser.strict.mode=false;
-SELECT TO_TIMESTAMP('2025-08-01','yyyy-MM-dd HH');
-执行结果: NULL
-```
-
-### cz.sql.cast.string.to.integer.allow\.truncate
-
-**默认值**：false
-
-控制字符串转整数时是否允许截断小数位。启用时，转换过程中的小数部分将被直接丢弃，与 Hive 的行为保持一致。
-
-**示例**：
-
-```sql
-SELECT CAST('11.4' AS INT);
-执行结果: NULL
-SET cz.sql.cast.string.to.integer.allow.truncate=true;
-SELECT CAST('11.4' AS INT) ;
-执行结果:11
-```

-# QUALIFY
-
-## 功能介绍
-
-QUALIFY 子句用于在 SELECT 语句中对窗口函数的结果进行过滤。QUALIFY 对窗口函数的作用就像 HAVING 对聚合函数和 GROUP BY 子句的作用一样。在查询的执行顺序中，QUALIFY 在窗口函数计算之后进行评估。
-
-QUALIFY 能够简化需要对窗口函数结果进行过滤的查询，无需使用子查询嵌套。这大大提高了 SQL 语句的可读性和简洁性。
-
-### QUALIFY 的执行顺序
-
-SELECT 语句中各子句的典型执行顺序如下：
-
-1. FROM
-2. WHERE
-3. GROUP BY
-4. HAVING
-5. Window Functions（窗口函数）
-6. **QUALIFY** ⭐
-7. DISTINCT
-8. ORDER BY
-9. LIMIT
-
-
-
-## 语法结构
-
-```sql
-SELECT <column_list>, <window_function> AS <alias>
-FROM <data_source>
-[WHERE ...]
-[GROUP BY ...]
-[HAVING ...]
-QUALIFY <predicate>
-[ORDER BY ...]
-[LIMIT ...]
-```
-
-### 参数说明
-
-* **column_list**：SELECT 子句中指定的列列表
-* **window_function**：窗口函数表达式，需要给定别名以便在 QUALIFY 子句中引用
-* **alias**：窗口函数的别名，在 QUALIFY 子句的谓词中使用
-* **data\_source**：数据源，通常是表
-* **predicate**：用于过滤的谓词表达式，使用窗口函数的别名
-
-
-
-## 使用说明
-
-### 必要条件
-
-QUALIFY 子句要求在 SELECT 语句中指定窗口函数并为其给定别名
-
-### 关键特性
-
-* 在 SELECT 子句中定义窗口函数时，**必须给定别名**
-* 在 QUALIFY 子句中使用该别名进行条件判断
-* 支持所有标准的窗口函数
-* 支持各种比较运算符（=, !=, <, >, <=, >=, IN 等）
-* QUALIFY 是保留字
-
-
-
-## 使用示例
-
-### 示例 1：获取每个分组的第一条记录
-
-**场景说明**：使用 ROW_NUMBER 获取每个分组中序号为 1 的记录
-
-**测试表**：
-
-```sql
-CREATE TABLE qualify_test (
-    i INT,
-    p CHAR(1),
-    o INT
-);
-
-INSERT INTO qualify_test VALUES 
-(1, 'A', 1),
-(2, 'A', 2),
-(3, 'B', 1),
-(4, 'B', 2);
-```
-
-**SQL 语句**：
-
-```sql
-SELECT i, p, o, ROW_NUMBER() OVER (PARTITION BY p ORDER BY o) as flag
-FROM qualify_test 
-QUALIFY flag = 1;
-```
-
-```
-i | p | o | flag
---|---|---|-----
-1 | A | 1 |  1
-3 | B | 1 |  1
-```
-
-
-
-### 示例 2：获取排序号大于 1 的记录
-
-**SQL 语句**：
-
-```sql
-SELECT i, p, o, ROW_NUMBER() OVER (PARTITION BY p ORDER BY o) as row_num
-FROM qualify_test 
-QUALIFY row_num > 1;
-```
-
-**执行结果**：
-
-```
-i | p | o | row_num
---|---|---|--------
-2 | A | 2 |   2
-4 | B | 2 |   2
-```
-
-
-
-
-
-### 示例 3：使用 RANK 函数获取排名前 2
-
-**SQL 语句**：

-```
-i | p | o | rnk
---|---|---|----
-4 | B | 2 |  1
-2 | A | 2 |  1
-```
-
-
-
-
-
-### 示例 4：使用 DENSE\_RANK 函数
-
-**SQL 语句**：
-
-```sql
-SELECT i, p, o, DENSE_RANK() OVER (PARTITION BY p ORDER BY o) as dense_rnk
-FROM qualify_test 
-QUALIFY dense_rnk = 1;
-```
-
-**执行结果**：
-
-```
-i | p | o | dense_rnk
---|---|---|----------
-1 | A | 1 |    1
-3 | B | 1 |    1
-```
-
-
-
-
-
-### 示例 5：使用聚合窗口函数
-
-**场景说明**： 获取分组总和大于等于 3 的所有行
-
-**SQL 语句**：
-
-```sql
-SELECT i, p, o, SUM(o) OVER (PARTITION BY p) as total
-FROM qualify_test 
-QUALIFY total >
-
-**执行结果**：
-
-```
-i | p | o | total
---|---|---|-----
-1 | A | 1 |  3
-2 | A | 2 |  3
-3 | B | 1 |  3
-4 | B | 2 |  3
-```
-
-
-
-
-## 与传统子查询的对比
-
-### 传统方式（使用子查询）
-
-```sql
-SELECT * FROM (
-    SELECT i, p, o, ROW_NUMBER() OVER (PARTITION BY p ORDER BY o) as row_num 
-    FROM qualify_test
-) t
-WHERE row_num = 1;
-```
-
-### QUALIFY 方式（推荐）
-
-```sql
-SELECT i, p, o, ROW_NUMBER() OVER (PARTITION BY p ORDER BY o) as row_num
-FROM qualify_test 
-QUALIFY row_num = 1;
-```
-
-### 优势对比
-
-| 方面     | 传统方式       | QUALIFY 方式 |
-| -------- | -------------- | ------------ |
-| 代码复杂度 | 高（嵌套子查询） | 低（平铺）     |
-| 可读性   | 一般           | 优秀 ✓       |
-| 代码行数 | 4-5 行         | 3 行         |
-| 性能     | 相当           | 相当         |
-| 维护成本 | 高             | 低 ✓         |
-
-
-
-
-
-## 注意事项
-
-### 必须遵循的规则
-
-* 窗口函数必须在 SELECT 子句中定义并给定别名
-* 在 QUALIFY 子句中使用窗口函数的别名进行条件判断
-* QUALIFY 必须引用至少一个窗口函数

-# 通过嵌套数据类型(Nested Data Types)进行数据转换
-
-## 基本概念
-
-SQL嵌套数据类型（Nested Data Types）允许在表的列中包含复杂的数据结构，如**STRUCT** 和 **ARRAY**。这些数据结构使得表示一对一、多对一以及层次关系变得更加简洁和清晰。
-
-* **STRUCT**: 表示包含多个相关列的单个字段，这些列可以表示对象的属性。
-* **ARRAY**: 表示包含多个结构字段的数组，适用于多对一关系。
-
-## 优势
-
-1. **简化数据模式**：使用STRUCT和ARRAY类型可以简化数据表的模式，使得存储和检索相关列数据更加方便。
-2. **提高查询性能**：嵌套数据类型可以减少表的联接操作，因为相关的数据已经在一个字段中嵌套好。
-3. **增强可读性**：嵌套结构使得数据模式更加直观，开发人员更容易理解和使用。
-4. **灵活的数据处理**：嵌套数据类型支持对复杂对象的灵活操作和排序，以及在数据处理过程中高效拆分和重组数据。
-
-## 使用场景
-
-* **一对一和层次关系**：适用于需要将多个相关字段组合在一起的场景，如用户信息和地址信息的组合。
-
-```sql
-SELECT 
-    c_custkey, 
-    STRUCT(c_name, c_address, c_phone) AS customer_info 
-FROM 
-    clickzetta_sample_data.tpch_100g.customer;
-```
-
-* **多对一关系**：适用于需要在一个字段中存储多个相关对象的场景，如订单和订单项的组合。
-
-```sql
-SELECT 
-    o.o_orderkey, 
-    ARRAY_AGG(STRUCT(o.o_clerk, o.o_totalprice, o.o_orderpriority)) AS items 
-FROM 
-    clickzetta_sample_data.tpch_100g.orders o 
-GROUP BY 
-    o.o_orderkey;
-```
-
-* **数据转换和清洗**：嵌套数据类型可以用于将数据拆分成更小的部分进行转换和清洗，然后再重新组合。
-
-```sql
--- 使用CTE定义orders_array
-WITH orders_array AS ( 
-    -- 聚合每个客户的所有订单ID到一个数组中
-    SELECT 
-        o_custkey,
-        ARRAY_AGG(o_orderkey) AS order_keys
-    FROM 
-        clickzetta_sample_data.tpch_100g.orders 
-    GROUP BY 
-        o_custkey
-),
--- 使用CTE定义modified_items
-modified_items AS (
-    -- 使用TRANSFORM函数将每个订单ID加1，生成新的数组
-    SELECT 
-        o_custkey,
-        TRANSFORM(order_keys, x -> x + 1) AS modified_order_keys
-    FROM 
-        orders_array
-)
--- 主查询部分
-SELECT 
-    c.c_custkey, 
-    mi.modified_order_keys
-FROM 
-    clickzetta_sample_data.tpch_100g.customer c 
--- 左连接modified_items，依据客户ID（c_custkey）
-LEFT JOIN 
-    modified_items mi
-ON 
-    c.c_custkey = mi.o_custkey;
-```
-
-:-: ![](.topwrite/assets/image_1736846123693.png =798)
-
-使用嵌套数据类型（如STRUCT和ARRAY）来进行数据转换，可以简化数据模式、提高查询性能，并增强数据处理的灵活性和可读性，为复杂数据结构的管理提供了有效的解决方案。

-
-## 数据模型
-
-TPC-H 数据代表一个汽车零部件销售商的数据仓库，其中记录了订单、构成订单的项目（lineitem）、供应商、客户、销售的零部件（part）、地区、国家和零部件供应商（partsupp）。
-
-云器Lakehouse内置了共享的TPC-H数据，每个用户可以通过加上数据上下文直接使用，比如：
-
-```sql
-SELECT * FROM 
-clickzetta_sample_data.tpch_100g.customer
-LIMIT 10;
-```
-
-## 通过云器Lakehouse嵌套数据类型进行数据转换
-
-### 有效使用嵌套数据类型
-
-#### 使用 STRUCT 处理一对一和层次关系
-
-```sql
--- 未使用嵌套数据类型
-SELECT l.*,
-c.*,
-s.*
-FROM 
-    clickzetta_sample_data.tpch_100g.lineitem l

-# SQL数据转换基础
-
-SQL数据转换（Data Transformation in SQL）是将数据从一种格式或结构转换为另一种格式或结构的过程。目的是清洗、整合和整形数据，以便其能被有效地存储、分析和利用。
-
-## 基本概念
-
-1. **抽取（Extract**）：从各种数据源（如数据库、文件系统）中提取数据。常见的操作包括数据查询和数据导出。
-2. **转换（Transform**）：对提取的数据进行各种操作以满足目标存储或分析的需求。常见的转换操作包括数据清洗、类型转换、数据聚合等。
-3. **加载（Load**）：将转换后的数据加载到目标存储系统，如数据仓库或数据湖中。
-
-## 常见的数据转换操作
-
-1. **数据清洗**：删除或修正数据中的噪声、重复和错误信息。例如：
-   * 删除空值：`DELETE FROM table_name WHERE column_name IS NULL;`
-   * 修正错误数据：`UPDATE table_name SET column_name = 'Correct Value' WHERE column_name = 'Incorrect Value';`
-
-2. **类型转换**：将数据从一种数据类型转换为另一种。例如：
-   * 将字符串转换为日期：`CAST(column_name AS DATE);`
-   * 将整数转换为字符串：`CAST(column_name AS STRING);`
-
-3. **数据聚合**：对数据进行汇总和统计，例如求和、平均值、计数等。例如：
-   * 计算总和：`SELECT SUM(column_name) FROM table_name;`
-   * 计算平均值：`SELECT AVG(column_name) FROM table_name;`
-
-4. **数据合并**：将来自不同表或数据源的数据进行合并。例如：
-   * 使用连接操作合并数据：`SELECT a.*, b.* FROM table_a a JOIN table_b b ON a.id = b.id;`
-   * 使用联合操作合并数据：`SELECT column_name FROM table_a UNION SELECT column_name FROM table_b;`
-
-5. **数据过滤**：选择符合条件的数据。例如：
-   * 获取特定条件的数据：`SELECT * FROM table_name WHERE column_name = 'value';`

-
-## 通过云器Lakehouse SQL 进行基本的数据转换
-
-### 获取数据
-
-使用 SELECT...FROM, LIMIT, WHERE, & ORDER BY 从表中读取所需数据。
-
-查询的最常见用途是从表中读取数据。我们可以使用 `SELECT ... FROM` 语句，如下所示。
-
-```sql
-SELECT
-  *
-FROM
-  clickzetta_sample_data.tpch_100g.customer
-LIMIT
-  1;
-```
-
-^
-
-```sql
--- 使用 * 来指定所有列
-SELECT
-  *
-FROM
-  clickzetta_sample_data.tpch_100g.orders
-LIMIT
-  5;
-```
-
-然而，运行 `SELECT ... FROM` 语句可能会在数据集很大时会出现问题。
-
-```sql
--- 只使用列名来读取这些列的数据
-SELECT
-  o_orderkey,
-  o_totalprice
-FROM
-  clickzetta_sample_data.tpch_100g.orders
-LIMIT
-  5;
-```
-
-如果我们想获取符合特定条件的行，可以使用 `WHERE` 子句。我们可以在 `WHERE` 子句中指定一个或多个过滤条件。
-
-`WHERE` 子句可以使用 `AND` 和 `OR` 条件组合多个过滤条件，如下所示。
-
-```sql
--- 所有 c_nationkey = 20 的客户行
-SELECT
-  *
-FROM
-  clickzetta_sample_data.tpch_100g.customer
-WHERE
-  c_nationkey = 20
-LIMIT
-  10;
-```
-
-^
-
-```sql
--- 所有 c_nationkey = 20 且 c_acctbal > 1000 的客户行
-SELECT
-  *
-FROM
-  clickzetta_sample_data.tpch_100g.customer
-WHERE
-  c_nationkey = 20
-  AND c_acctbal > 1000
-LIMIT
-  10;
-```
-
-```sql
--- 所有 c_nationkey = 20 或 c_acctbal > 1000 的客户行
-SELECT
-  *
-FROM
-  clickzetta_sample_data.tpch_100g.customer
-WHERE
-  c_nationkey = 20
-  OR c_acctbal > 1000
-LIMIT
-  10;
-```
-
-```sql
--- 所有 (c_nationkey = 20 且 c_acctbal > 1000) 或 c_nationkey = 11 的客户行
-SELECT
-  *
-FROM
-  clickzetta_sample_data.tpch_100g.customer
-WHERE
-  (
-    c_nationkey = 20
-    AND c_acctbal > 1000
-  )
-  OR c_nationkey = 11
-LIMIT
-  10;
-```
-
-我们可以组合多个过滤条件，如上所示。我们已经看到了等于 (`=`) 和大于 (`>`) 条件运算符。共有 6 个 **条件运算符**，它们是：
-
-1. < 小于
-2. \> 大于
-3. <= 小于或等于
-4. \>= 大于或等于
-5. \= 等于
-6. <> 和 != 都表示不等于（某些数据库只支持其中一个）
-
-此外，对于字符串类型，我们可以使用 `like` 条件进行 **模式匹配**。在 `like` 条件中，`_` 表示任意单个字符，`%` 表示零个或多个字符，例如。
-
-```sql
--- 所有 c_name 包含 381 的客户行
-SELECT
-  *
-FROM
-  clickzetta_sample_data.tpch_100g.customer
-WHERE
-  c_name LIKE '%381%';
-```
-
-^
-
-```sql
--- 所有 c_name 包含任意字符、9 和 1 的客户行
-SELECT
-  *
-FROM
-  clickzetta_sample_data.tpch_100g.customer
-WHERE
-  c_name LIKE '%_91%';
-```
-
-我们还可以使用 `IN` 和 `NOT IN` 来过滤多个值。
-
-^
-
-```sql
--- 所有 c_nationkey = 10 或 c_nationkey = 20 的客户行
-SELECT
-  *
-FROM
-  clickzetta_sample_data.tpch_100g.customer
-WHERE
-  c_nationkey IN (10, 20);
-```
-
-可以使用 `count(*)` 来获取表中的行数，如下所示。
-
-^
-
-```sql
-SELECT
-  COUNT(*)
-FROM
-  clickzetta_sample_data.tpch_100g.lineitem;
-```
-
-^
-
-```sql
-SELECT  COUNT(*)FROM  clickzetta_sample_data.tpch_100g.lineitem;
-```
-
-如果我们想按特定列的值对行进行排序，可以使用 `ORDER BY`，例如。
-
-^
-
-```sql
--- 显示 custkey 最小的前十个客户记录
--- 行默认按升序排序
-SELECT
-  *
-FROM
-  clickzetta_sample_data.tpch_100g.orders
-ORDER BY
-  o_custkey
-LIMIT
-  10;
-```
-
-### 连接Join
-
-使用 JOINs 结合多个表的数据（有不同类型的 JOINs）。
-
-我们可以使用连接来结合多个表的数据。编写连接查询时，格式如下所示。
-
-^
-
-```sql
--- 基于非真实表
-SELECT
-    a.*
-FROM
-    table_a a -- 左表 a
-    JOIN table_b b -- 右表 b
-    ON a.id = b.id
-```
-
-首先指定的表（table\_a）是左表，而第二个指定的表是右表。当有多个表连接时，我们将前两个表的连接数据集视为左表，第三个表视为右表（数据库会优化连接以提高性能）。
-
-^
-
-```sql
--- 基于非真实表
-SELECT
-    a.*
-FROM
-    table_a a -- 左表 a
-    JOIN table_b b -- 右表 b
-    ON a.id = b.id
-    JOIN table_c c -- 左表是 table_a 和 table_b 的连接数据，右表是 table_c
-    ON a.c_id = c.id
-```
-
-主要有五种连接类型，它们是：
-
-#### 1. 内连接（默认）：仅获取两个表中都存在的行
-
-^
-
-```sql
-SELECT
-  o.o_orderkey,
-  l.l_orderkey
-FROM
-  clickzetta_sample_data.tpch_100g.orders o
-  JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
-  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY
-LIMIT
-  100;
-```
-
-^
-
-```sql
-SELECT
-  COUNT(o.o_orderkey) AS order_rows_count,
-  COUNT(l.l_orderkey) AS lineitem_rows_count
-FROM
-  clickzetta_sample_data.tpch_100g.orders o
-  JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
-  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY;
-```
-
-**注意**：连接默认为内连接。
-
-输出将包含订单和行项目中至少找到一个匹配行的记录（相同的 o\_orderkey 且订单日期在发货日期前后 5 天内）。
-
-我们还可以看到订单和行项目表中有24792743行匹配。
-
-#### 2. 左外连接（又称左连接）：获取左表的所有行和右表的匹配行
-
-```sql
-SELECT
-  o.o_orderkey,
-  l.l_orderkey
-FROM
-  clickzetta_sample_data.tpch_100g.orders o
-  LEFT JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
-  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY
-LIMIT
-  100;
-```
-
-^
-
-```sql
-SELECT
-  COUNT(o.o_orderkey) AS order_rows_count,
-  COUNT(l.l_orderkey) AS lineitem_rows_count
-FROM
-  clickzetta_sample_data.tpch_100g.orders o
-  LEFT JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
-  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY;
-```
-
-输出将包含订单表的所有行和行项目表中至少找到一个匹配行的记录（相同的 o\_orderkey 且订单日期在发货日期前后 5 天内）。
-
-我们还可以看到订单表有 151947677 行，行项目表有24792743 行。订单表的行数为 1,500,000，但由于连接条件，产生了 151947677 行，因为一些订单与多个行项目匹配。
-
-#### 3. 右外连接（又称右连接）：获取左表的匹配行和右表的所有行
-
-```sql
-SELECT
-  o.o_orderkey,
-  l.l_orderkey
-FROM
-  clickzetta_sample_data.tpch_100g.orders o
-  RIGHT JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
-  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY
-LIMIT
-  100;
-```
-
-^
-
-```sql
-SELECT
-  COUNT(o.o_orderkey) AS order_rows_count,
-  COUNT(l.l_orderkey) AS lineitem_rows_count
-FROM
-  clickzetta_sample_data.tpch_100g.orders o
-  RIGHT JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
-  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY;
-```
-
-输出将包含订单表中至少找到一个匹配行的记录（相同的 o\_orderkey 且订单日期在发货日期前后 5 天内）和行项目表的所有行。
-
-我们还可以看到订单表有 24792743 行，行项目表有 600037902 行。
-
-#### 4. 全外连接：获取左表和右表的所有行
-
-```sql
-SELECT
-  o.o_orderkey,
-  l.l_orderkey
-FROM
-  clickzetta_sample_data.tpch_100g.orders o
-  FULL OUTER JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
-  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY
-LIMIT
-  100;
-```
-
-^
-
-```sql
-SELECT
-  COUNT(o.o_orderkey) AS order_rows_count,
-  COUNT(l.l_orderkey) AS lineitem_rows_count
-FROM
-  clickzetta_sample_data.tpch_100g.orders o
-  FULL OUTER JOIN clickzetta_sample_data.tpch_100g.lineitem l ON o.o_orderkey = l.l_orderkey
-  AND o.o_orderdate BETWEEN l.l_shipdate - INTERVAL '5' DAY AND l.l_shipdate  + INTERVAL '5' DAY;
-```
-
-输出将包含订单表中至少找到一个匹配行的记录（相同的 o\_orderkey 且订单日期在发货日期前后 5 天内）和行项目表的所有行。
-
-我们还可以看到订单表有 151947677 行，行项目表有 600037902 行。
-
-#### 5. 交叉连接：获取所有行的笛卡尔积
-
-```sql
-SELECT
-  n.n_name AS nation_c_name,
-  r.r_name AS region_c_name
-FROM
-  clickzetta_sample_data.tpch_100g.nation n
-  CROSS JOIN clickzetta_sample_data.tpch_100g.region r;
-```
-
-输出将包含国家表的每一行与地区表的每一行的连接。共有 25 个国家和 5 个地区，因此交叉连接的结果有 125 行。
-
-^
-
-有时我们需要将表与自身连接，称为自连接。
-
-**示例**：
-
-1. 对于每个客户订单，获取同一周（周日 - 周六，不是前七天）内较早放置的订单。仅显示至少有一个此类订单的客户订单。
-
-```sql
-SELECT
-  o1.o_custkey
-FROM
-  clickzetta_sample_data.tpch_100g.orders o1
-  JOIN clickzetta_sample_data.tpch_100g.orders o2 ON o1.o_custkey = o2.o_custkey
-  AND YEAR (o1.o_orderdate) = YEAR (o2.o_orderdate)
-  AND week (o1.o_orderdate) = week (o2.o_orderdate)
-WHERE
-  o1.o_orderkey != o2.o_orderkey;
-```
-
-大多数分析查询需要计算涉及多个行的数据指标。`GROUP BY` 允许我们对基于指定列值分组的行集进行聚合计算。
-
-**示例**：
-
-1. 创建一个报告，显示每个订单优先级段的订单数量。
-
-```sql
-SELECT
-  o_orderpriority,
-  COUNT(*) AS num_orders
-FROM
-  clickzetta_sample_data.tpch_100g.orders
-GROUP BY
-  o_orderpriority;
-```
-
-在上述查询中，我们按 `orderpriority` 分组，`count(*)` 计算将应用于具有特定 `orderpriority` 值的行。输出将包含每个唯一 `orderpriority` 值的一行和 `count(*)` 计算。
-
-^
-
-允许的计算通常是 SUM/MIN/MAX/AVG/COUNT。然而，某些数据库有更复杂的聚合函数；请查阅您的数据库文档。
-
-### 子查询
-
-使用子查询在查询中使用查询结果。
-
-当我们想将一个查询的结果作为另一个查询的表时，我们使用子查询。**示例**：
-
-1. 创建一个报告，显示国家、该国供应的项目数量（由该国的供应商供应）以及该国购买的项目数量（由该国的客户购买）。
-
-```sql
-SELECT
-  n.n_name AS nation_c_name,
-  s.quantity AS supplied_items_quantity,
-  c.quantity AS purchased_items_quantity
-FROM
-  clickzetta_sample_data.tpch_100g.nation n
-  LEFT JOIN (
-    SELECT
-      n.n_nationkey,
-      SUM(l.l_quantity) AS quantity
-    FROM
-      clickzetta_sample_data.tpch_100g.lineitem l
-      JOIN clickzetta_sample_data.tpch_100g.supplier s ON l.l_suppkey = s.s_suppkey
-      JOIN clickzetta_sample_data.tpch_100g.nation n ON s.s_nationkey = n.n_nationkey
-    GROUP BY
-      n.n_nationkey
-  ) s ON n.n_nationkey = s.n_nationkey
-  LEFT JOIN (
-    SELECT
-      n.n_nationkey,
-      SUM(l.l_quantity) AS quantity
-    FROM
-      clickzetta_sample_data.tpch_100g.lineitem l
-      JOIN clickzetta_sample_data.tpch_100g.orders o ON l.l_orderkey = o.o_orderkey
-      JOIN clickzetta_sample_data.tpch_100g.customer c ON o.o_custkey = c.c_custkey
-      JOIN clickzetta_sample_data.tpch_100g.nation n ON c.c_nationkey = n.n_nationkey
-    GROUP BY
-      n.n_nationkey
-  ) c ON n.n_nationkey = c.n_nationkey;
-```
-
-在上述查询中，我们可以看到有两个子查询，一个用于计算一个国家供应的项目数量，另一个用于计算该国客户购买的项目数量。
-
-### CASE WHEN&#x20;
-
-使用 CASE 语句复制 IF.ELSE 逻辑。
-
-我们可以在查询的 `SELECT ... FROM` 部分进行条件逻辑，如下所示。
-
-```sql
-SELECT
-    o_orderkey,
-    o_totalprice,
-    CASE
-        WHEN o_totalprice > 100000 THEN 'high'
-        WHEN o_totalprice BETWEEN 25000
-        AND 100000 THEN 'medium'
-        ELSE 'low'
-    END AS order_price_bucket
-FROM
-    clickzetta_sample_data.tpch_100g.orders;
-```
-
-我们可以看到如何根据 `totalprice` 列显示不同的值。我们还可以使用多个条件作为我们的条件标准（例如，totalprice > 100000 AND orderpriority = '2-HIGH'）。
-
-### 标准函数
-
-使用标准内置数据库函数进行常见的字符串、时间和数字数据操作。
-
-在处理数据时，我们通常需要更改列中的值；以下是一些需要了解的标准函数：
-
-1. **字符串函数**
-
-   1. **LENGTH** 用于计算字符串的长度。例如，`SELECT LENGTH('hi');` 将输出 2。
-   2. **CONCAT** 将多个字符串列合并为一个。例如，`SELECT CONCAT(o_orderstatus, '-', o_orderpriority) FROM clickzetta_sample_data.tpch_100g.orders LIMIT 5;` 将连接 o\_orderstatus 和 o\_orderpriority 列，中间用短横线分隔。
-   3. **SPLIT** 用于根据给定的分隔符将值拆分为数组。例如，`SELECT STRING_SPLIT(o_orderpriority, '-') FROM clickzetta_sample_data.tpch_100g.orders LIMIT 5;` 将输出一个列，其中的数组是通过在 `-` 处拆分 o\_orderpriority 值形成的。
-   4. **SUBSTRING** 用于从值中获取子字符串，给定起始和结束字符索引。例如，`SELECT o_orderpriority, SUBSTRING(o_orderpriority, 1, 5) FROM clickzetta_sample_data.tpch_100g.orders LIMIT 5;` 将获取 o\_orderpriority 列的前五个（1 - 5）字符。
-   5. **TRIM** 用于删除值左右两侧的空格。例如，`SELECT TRIM(' hi ');` 将输出 `hi`，周围没有空格。LTRIM 和 RTRIM 类似，但分别只删除字符串前后的空格。
-
-2. **日期和时间函数**
-
-   1. **添加和减去日期**：用于添加和减去时间段；格式在很大程度上取决于数据库。在 Lakehouse 中，`datediff` 接受 3 个参数，输出单位（天、月、年），日期/时间值 a 和 b，使得输出为 a - b。`+ INTERVAL n UNIT(DAY/MONTH/YEAR)` 将指定单位的值添加到时间戳值中。
-
-      ```sql
-        -- 日期和时间函数
-        SELECT
-            datediff(day, DATE '2022-10-01', DATE '2023-11-05') AS diff_in_days,
-            datediff(month, DATE '2022-10-01', DATE '2023-11-05') AS diff_in_months,
-            datediff(year, DATE '2022-10-01', DATE '2023-11-05') AS diff_in_years,
-            DATE '2022-10-01' + INTERVAL 400 DAY AS new_date;
-      ```
-
-   它将显示两个日期之间指定时间段的差异。我们还可以从日期/时间列中添加/减去任意时间段。例如，`SELECT DATE '2022-11-05' + INTERVAL '10' DAY;` 将显示输出 `2022-11-15`（尝试日期减法）。
-
-   ^
-
-3. **字符串 <=> 日期/时间转换**
-
-当我们想将字符串的数据类型更改为日期/时间时，我们可以使用 `DATE 'YYYY-MM-DD'` 或 `TIMESTAMP 'YYYY-MM-DD HH:mm:SS'` 函数。但如果数据是非标准日期/时间格式，如 `MM/DD/YYYY`，我们需要指定输入结构；我们使用 `date\_format` 来实现这一点，例如：
-
-```sql
-SELECT date_format('2023-05-11', 'M-d-y');
-```
-
-我们可以使用 `date_format` 将时间戳/日期转换为所需格式的字符串。例如：
-
-```sql
-SELECT date_format(o_orderdate, 'yyyy-MM-01') AS first_month_date FROM clickzetta_sample_data.tpch_100g.orders LIMIT 5;
-```
-
-请参阅 [此页面](sql_functions/scalar_functions/datetime_functions/date_format.md) 了解如何设置正确的日期时间格式。
-
-4. **时间框架函数（YEAR/MONTH/DAY**）：当我们想从日期/时间列中提取特定时间段时，我们可以使用这些函数。例如，`SELECT year(DATE '2023-11-05');` 将返回 2023。类似地，我们还有 month、day、hour、min 等。
-
-请参阅 [此页面](time-function.md) 了解更多的时间函数。
-
-5. **数字**
-
-   1. **ROUND** 用于指定小数点后允许的位数。例如，`SELECT ROUND(100.102345, 2);`
-   2. **ABS** 用于获取给定数字的绝对值。例如，`SELECT ABS(-100), ABS(100);`
-   3. **数学运算** 例如， +,-,\*,/。
-   4. **Ceil/Floor** 用于获取给定小数的下一个更高和最近的较低整数。例如，`SELECT CEIL(100.1), FLOOR(100.1);`

-# 通过CTE进行数据转换
-
-让我们先了解一下使用Lakehouse SQL的[公用表表达式（Common Table Expression, CTE）](WITH.md)进行数据转换的基本概念、优势以及常见的使用场景。
-
-## 基本概念
-
-公用表表达式（CTE）是一种可以在SQL查询中定义临时结果集的表达式。该结果集在查询的执行过程中存在，通常用于简化复杂查询、递归查询或分解查询步骤。CTE通常由[WITH关键字](WITH.md)引入，并可以在随后的`SELECT`、`INSERT`、`UPDATE`和`DELETE`语句中使用。
-
-基本语法：
-
-```sql
-WITH cte_name AS (
-    SELECT column1, column2, ...
-    FROM table_name
-    WHERE condition
-)
-SELECT * FROM cte_name;
-```
-
-## 优势
-
-1. **可读性高**：CTE可以使复杂查询更具可读性和可维护性。通过将复杂的查询逻辑拆解为多个可理解的部分，CTE增强了查询的结构化和清晰度。CTE 使测试复杂查询更简单
-
-   * CTE 是一个可以在单个查询中重用的 `SELECT` 语句。
-   * 复杂的 SQL 查询通常涉及多个子查询。多个子查询会使代码难以阅读。
-   * 使用公共表表达式（CTE）可以使你的查询更易读。
-
-2. **复用性强**：CTE可以在同一查询中多次引用，从而避免重复代码，提高查询的复用性。
-
-3. **步骤化数据转换**：CTE可以将数据转换过程分步骤实现，每个步骤都可以定义为一个独立的CTE，这样便于调试和测试。
-
-## 使用场景
-
-以下是一些利用CTE进行数据转换的常见场景：
-
-### 1. 数据清洗和转换
-
-通过CTE可以分步骤清洗和转换数据，例如去除重复值、修正数据格式：
-
-```sql
-WITH cleaned_data AS (
-    SELECT DISTINCT column1, column2
-    FROM raw_table
-    WHERE column1 IS NOT NULL
-),
-transformed_data AS (
-    SELECT column1, UPPER(column2) AS transformed_column2
-    FROM cleaned_data
-)
-SELECT * FROM transformed_data;
-```
-
-### 2. 分组和聚合
-
-CTE可以用于进行复杂的分组和聚合操作，并在后续查询中引用聚合结果：
-
-```sql
-WITH total_sales AS (
-    SELECT customer_id, SUM(order_amount) AS total_spent
-    FROM orders
-    GROUP BY customer_id
-)
-SELECT customer_id, total_spent
-FROM total_sales
-WHERE total_spent > 1000;
-```
-
-### 3. 数据合并和连接
-
-使用CTE，可以简化多表连接和数据合并操作：
-
-```sql
-WITH customer_orders AS (
-    SELECT c.customer_id, c.customer_name, o.order_id, o.order_date
-    FROM customers c
-    JOIN orders o ON c.customer_id = o.customer_id
-)
-SELECT *
-FROM customer_orders
-WHERE order_date > '2024-01-01';
-```
-
-## 数据模型

-TPC-H 数据代表一个汽车零部件销售商的数据仓库，其中记录了订单、构成订单的项目（lineitem）、供应商、客户、销售的零部件（part）、地区、国家和零部件供应商（partsupp）。
-
-云器Lakehouse内置了共享的TPC-H数据，每个用户可以通过加上数据上下文直接使用，比如：

-clickzetta_sample_data.tpch_100g.customer
-LIMIT 10;
-```
-
-## 通过云器Lakehouse SQL CTE进行数据转换
-
-### 如何定义 CTE
-
-```sql
--- CTE 定义
-WITH
-  supplier_nation_metrics AS ( -- 使用 WITH 关键字定义 CTE 1
-    SELECT
-      n.n_nationkey,
-      SUM(l.l_QUANTITY) AS num_supplied_parts
-    FROM
-      clickzetta_sample_data.tpch_100g.lineitem l
-      JOIN clickzetta_sample_data.tpch_100g.supplier s ON l.l_suppkey = s.s_suppkey
-      JOIN clickzetta_sample_data.tpch_100g.nation n ON s.s_nationkey = n.n_nationkey
-    GROUP BY
-      n.n_nationkey
-  ),
-  buyer_nation_metrics AS ( -- 定义 CTE 2
-    SELECT
-      n.n_nationkey,
-      SUM(l.l_QUANTITY) AS num_purchased_parts
-    FROM
-      clickzetta_sample_data.tpch_100g.lineitem l
-      JOIN clickzetta_sample_data.tpch_100g.orders o ON l.l_orderkey = o.o_orderkey
-      JOIN clickzetta_sample_data.tpch_100g.customer c ON o.o_custkey = c.c_custkey
-      JOIN clickzetta_sample_data.tpch_100g.nation n ON c.c_nationkey = n.n_nationkey
-    GROUP BY
-      n.n_nationkey
-  )
-SELECT -- 最终的 SELECT 语句前不需要逗号
-  n.n_name AS nation_name,
-  s.num_supplied_parts,
-  b.num_purchased_parts
-FROM
-  clickzetta_sample_data.tpch_100g.nation n
-  LEFT JOIN supplier_nation_metrics s ON n.n_nationkey = s.n_nationkey
-  LEFT JOIN buyer_nation_metrics b ON n.n_nationkey = b.n_nationkey
-LIMIT 10;
-```
-
-### 计算因折扣而损失的金额
-
-使用 `lineitem` 表获取订单中项目的价格（不含折扣），并与订单进行比较。先确定比较需要进行的粒度。分步骤思考，即先获取订单中所有项目的不含折扣的价格，然后将其与已计算折扣的 `totalprice` 的订单数据进行比较。
-
-```sql
-WITH lineitem_agg AS (
-    SELECT 
-        l_orderkey,
-        SUM(l_extendedprice) AS total_price_without_discount
-    FROM 
-        clickzetta_sample_data.tpch_100g.lineitem
-    GROUP BY 
-        l_orderkey
-)
-SELECT 
-    o.o_orderkey,
-    o.o_totalprice, 
-    l.total_price_without_discount - o.o_totalprice AS amount_lost_to_discount
-FROM 
-    clickzetta_sample_data.tpch_100g.orders o
-JOIN 
-    lineitem_agg l ON o.o_orderkey = l.l_orderkey
-ORDER BY 
-    o.o_orderkey;
-```
-
-### 不要过度使用 CTE。注意代码的可读性。
-
-1. CTE 可以帮助提高查询的可读性和可重用性。
-
-2. 不要过度使用 CTE；注意查询的大小。
-
-   * 多个临时表的 SQL 查询比带有众多 CTE 的 1000 行 SQL 查询更好。
-   * 保持每个查询中的 CTE 数量较小（取决于查询的大小，但通常 < 5）。
-
-3. 如果对CTE 的性有疑问，请检查你的查询计划。

-
-## 1. 常见数据处理场景的实用函数
-
-### 1.1. 需要分区中的第一/最后一行时使用 ROW\_NUMBER
-
-```sql
-SELECT 
-    o_custkey, 
-    o_orderdate, 
-    o_totalprice
-FROM (
-    SELECT 
-        o_custkey, 
-        o_orderdate, 
-        o_totalprice,
-        ROW_NUMBER() OVER (PARTITION BY o_custkey ORDER BY o_orderdate DESC) AS rn
-    FROM clickzetta_sample_data.tpch_100g.orders
-) t
-WHERE rn = 1;
-```
-
-### 1.2. STRUCT 数据类型按其键从左到右排序
-
-```sql
-WITH order_struct AS (
-    SELECT 
-        o_orderkey,
-        struct(o_orderdate, o_totalprice, o_orderkey) AS order_info
-    FROM clickzetta_sample_data.tpch_100g.orders
-)
-SELECT 
-    MIN(order_info) AS min_order_date,
-    MAX(order_info) AS max_order_date_price
-FROM order_struct;
-```
-
-### 1.3. 使用 BOOL\_OR 和 BOOL\_AND 分别检查至少一个或所有布尔值是否为真
-
-```sql
-SELECT 
-    o_custkey, 
-    BOOL_OR(o_shippriority > 0) AS has_atleast_one_priority_order,
-    BOOL_AND(o_shippriority > 0) AS has_all_priority_order
-FROM clickzetta_sample_data.tpch_100g.orders
-GROUP BY o_custkey;
-```
-
-### 1.4. 想要选择除少数列之外的所有列时使用 EXCEPT
-
-```sql
-SELECT * EXCEPT(o_orderdate, o_totalprice)
-FROM clickzetta_sample_data.tpch_100g.orders;
-```
-
-### 1.5. 厌倦了在 GROUP BY 中创建长长的列列表时使用 GROUP BY ALL
-
-```sql
-SELECT 
-    o_orderkey, 
-    o_custkey, 
-    o_orderstatus, 
-    SUM(o_totalprice) AS total_price
-FROM clickzetta_sample_data.tpch_100g.orders
-GROUP BY ALL;
-```
-
-### 1.6. ORDER、GROUP字段用SELECT字段的序号代替
-
-```sql
-SELECT 
-    o_orderkey, 
-    o_custkey, 
-    o_orderstatus, 
-    SUM(o_totalprice) AS total_price
-FROM clickzetta_sample_data.tpch_100g.orders
-GROUP BY 1,2,3
-ORDER BY 3,2,1;
-```
-
-### 1.7. 需要仅在满足特定条件时计数行时使用 COUNT IF
-
-```sql
-SELECT 
-    o_custkey, 
-    COUNT_IF(o_totalprice > 100000) AS high_value_orders,
-    COUNT(o_totalprice) as all_orders
-FROM clickzetta_sample_data.tpch_100g.orders
-GROUP BY o_custkey;
-```
-
-### 1.8. 使用 COALESCE 处理空列值与其他列或回退值
-
-```sql
-WITH fake_orders AS (
-    SELECT 1 AS o_orderkey, 100 AS o_totalprice, NULL AS discount
-    UNION ALL
-    SELECT 2 AS o_orderkey, 200 AS o_totalprice, 20 AS discount
-    UNION ALL
-    SELECT 3 AS o_orderkey, 300 AS o_totalprice, NULL AS discount
-)
-SELECT 
-    o_orderkey, 
-    o_totalprice, 
-    discount,
-    COALESCE(discount, o_totalprice * 0.10) AS final_discount
-FROM fake_orders;
-```
-
-### 1.9. 使用 sequence和explode 生成数字/日期行范围
-
-```sql
-SELECT explode(sequence(1, 10)) AS num;
-```
-
-^
-
-```sql
-SELECT    EXPLODE (
-          sequence(
-          to_date('2024-01-01'),
-          to_date('2024-01-10'),
-          interval 1 DAY
-          )
-          ) AS date;
-```
-
-### 1.10. 使用 UNNEST 将 ARRAY/LIST 元素转换为单独的行
-
-```sql
-WITH nested_data AS (
-    SELECT 1 AS id, array(10, 20, 30) AS values
-    UNION ALL
-    SELECT 2 AS id, array(40, 50) AS values
-)
-SELECT 
-    id, 
-    unnest(values) AS flattened_value
-FROM nested_data;
-```
-
-## 2. 另一个表中的存在/不存在的数据获取
-
-### 2.1. 根据另一个表中的数据存在性获取表中的数据时使用 EXISTS
-
-```sql
-SELECT 
-    c_custkey, 
-    c_name
-FROM clickzetta_sample_data.tpch_100g.customer c
-WHERE EXISTS (
-    SELECT o_orderkey
-    FROM clickzetta_sample_data.tpch_100g.orders o
-    WHERE o.o_custkey = c.c_custkey AND o.o_totalprice > 1000
-);
-```
-
-### 2.2. 获取两个表中都存在的数据时使用 INTERSECT
-
-```sql
-SELECT    c_custkey
-FROM      clickzetta_sample_data.tpch_100g.customer
-INTERSECT
-SELECT    o_custkey
-FROM      clickzetta_sample_data.tpch_100g.orders;
-```
-
-### 2.3. 获取表 1 中存在但表 2 中不存在的数据时使用 EXCEPT
-
-```sql
-SELECT c_custkey
-FROM clickzetta_sample_data.tpch_100g.customer
-EXCEPT
-SELECT o_custkey
-FROM clickzetta_sample_data.tpch_100g.orders;
-```
-
-### 2.4. 获取数据差异（即 delta），使用 (A - B) U (B - A)
-
-```sql
-SELECT c_custkey, 'DELETED' as ops FROM ( 
-SELECT c_custkey
-FROM clickzetta_sample_data.tpch_100g.customer
-EXCEPT
-SELECT c_custkey
-FROM clickzetta_sample_data.tpch_100g.customer
-)
-
-UNION ALL
-
-SELECT c_custkey, 'UPSERTED' as ops FROM ( 
-SELECT c_custkey, c_name, c_address
-FROM clickzetta_sample_data.tpch_100g.customer
-EXCEPT
-SELECT c_custkey, c_name, c_address
-FROM clickzetta_sample_data.tpch_100g.customer
-);
-```
-
-## 3. 在 SQL 中CASE 语句
-
-### 3.1. 使用 CASE 语句
-
-```sql
-SELECT 
-    o_orderkey, 
-    o_totalprice,
-    CASE
-        WHEN o_totalprice > 100000 THEN 'Large Order'
-        ELSE 'Regular Order'
-    END AS order_type
-FROM clickzetta_sample_data.tpch_100g.orders
-LIMIT 5;
-```
-
-## 4. 访问关于数据的元数据
-
-### 4.1. 访问在 information\_schema 中存储的元数据
-
-```sql
--- 查看表的信息
-DESCRIBE TABLE clickzetta_sample_data.tpch_100g.orders;
-```
-
-```sql
--- 查看所有表
-SHOW TABLES IN clickzetta_sample_data.tpch_100g;
-```
-
-^
-
-## 5. 使用 UPSERTS（即 MERGE INTO）避免数据重复
-
-### 5.1. 使用 UPSERT/MERGE INTO 插入新数据，更新现有数据
-
-```sql
-MERGE INTO dim_customer_scd2 AS target
-USING (
-    VALUES
-        (1, 'Customer#000000001', 'New Address 1', 15, '25-989-741-2988', 711.56, 'BUILDING', 'comment1', '2024-10-18', NULL, TRUE),
-        (2, 'Customer#000000002', 'New Address 2', 18, '12-423-790-3665', 879.49, 'FURNITURE', 'comment2', '2024-10-18', NULL, TRUE),
-        (1501, 'Customer#000001501', 'New Address 1501', 24, '11-345-678-9012', 500.50, 'MACHINERY', 'comment1501', '2024-10-18', NULL, TRUE),
-        (1502, 'Customer#000001502', 'New Address 1502', 21, '22-456-789-0123', 600.75, 'AUTOMOBILE', 'comment1502', '2024-10-18', NULL, TRUE)
-) AS source (c_custkey, c_name, c_address, c_nationkey, c_phone, c_acctbal, c_mktsegment, c_comment, valid_from, valid_to, is_current)
-ON target.c_custkey = source.c_custkey
-WHEN MATCHED AND target.is_current = TRUE THEN
-    UPDATE SET valid_to = source.valid_from, is_current = FALSE
-WHEN NOT MATCHED THEN
-    INSERT (c_custkey, c_name, c_address, c_nationkey, c_phone, c_acctbal, c_mktsegment, c_comment, valid_from, valid_to, is_current)
-    VALUES (source.c_custkey, source.c_name, source.c_address, source.c_nationkey, source.c_phone, source.c_acctbal, source.c_mktsegment, source.c_comment, source.valid_from, source.valid_to, source.is_current);
-```
-
-## 6. 高级 JOIN 类型
-
-### 6.1. 使用JOIN和ROW\_NUMBER获取表 2 中与表 1 行时间最接近的值
-
-```sql
-WITH stock_prices_data AS (
-    SELECT 'APPL' AS ticker, to_timestamp('2001-01-01 00:00:00') AS ts, 1 AS price

-    UNION ALL
-    SELECT 'GOOG', to_timestamp('2001-01-01 00:00:30'), 23.45
-    UNION ALL
-    SELECT 'GOOG', to_timestamp('2001-01-01 00:01:30'), 10.58

-    UNION ALL
-    SELECT 'DATA', to_timestamp('2001-01-01 00:00:30'), 17.95
-    UNION ALL
-    SELECT 'DATA', to_timestamp('2001-01-01 00:01:30'), 18.37
-)
-SELECT h.ticker,
-    h.ts AS holdings_ts,
-    p.ts AS stock_price_ts,
-    p.price,
-    h.shares,
-    p.price * h.shares AS value
-FROM portfolio_holdings_data h
-JOIN (
-    SELECT 
-        ticker, 
-        ts, 
-        price,
-        ROW_NUMBER() OVER (PARTITION BY ticker ORDER BY ts DESC) AS rn
-    FROM stock_prices_data
-) p
-ON h.ticker = p.ticker AND h.ts >= p.ts
-WHERE p.rn = 1
-ORDER BY h.ticker, h.ts;
-```
-
-### 6.2. 使用 ANTI JOIN 获取表 1 中存在但表 2 中不存在的行
-
-```sql
-SELECT    c.c_custkey
-FROM      clickzetta_sample_data.tpch_100g.customer c
-LEFT      ANTI JOIN clickzetta_sample_data.tpch_100g.orders o ON c.c_custkey = o.o_custkey
-ORDER BY  c.c_custkey
-LIMIT     5;
-```
-
-### 6.3. 使用 LATERAL JOIN 对表 1 中的每一行连接表 2 中的所有“匹配”行
-
-```sql
-SELECT    o.o_orderkey,
-          o.o_totalprice,
-          l.l_linenumber,
-          l.l_extendedprice
-FROM      clickzetta_sample_data.tpch_100g.orders o
-CROSS     JOIN clickzetta_sample_data.tpch_100g.lineitem l
-WHERE     l.l_orderkey = o.o_orderkey AND      
-          l.l_linenumber <= 2 AND      
-          l.l_extendedprice < (o.o_totalprice / 2)
-ORDER BY  o.o_orderkey,
-          l.l_linenumber;
-```
-
-## 7 业务用例
-
-### 7.1. 使用 CASE和 `GROUP BY `将维度值转换为单独的列
-
-```sql
-SELECT    o_custkey,
-          SUM(
-          CASE
-                    WHEN o_orderstatus = 'F' THEN o_totalprice
-                    ELSE 0
-          END
-          ) AS fulfilled_total,
-          SUM(
-          CASE
-                    WHEN o_orderstatus = 'O' THEN o_totalprice
-                    ELSE 0
-          END
-          ) AS open_total,
-          SUM(
-          CASE
-                    WHEN o_orderstatus = 'P' THEN o_totalprice
-                    ELSE 0
-          END
-          ) AS pending_total
-FROM      clickzetta_sample_data.tpch_100g.orders
-GROUP BY  o_custkey
-ORDER BY  o_custkey;
-```
-
-### 7.2. 使用 CUBE 生成每个可能维度组合的指标
-
-```sql
-SELECT    o_orderpriority,
-          o_orderstatus,
-          EXTRACT(
-          YEAR
-          FROM      o_orderdate
-          ) AS order_year,
-          SUM(o_totalprice) AS total_sales
-FROM      clickzetta_sample_data.tpch_100g.orders
-GROUP BY  CUBE (o_orderpriority, o_orderstatus, order_year)
-ORDER BY  1,
-          2,
-          3;
-```

-# 通过窗口函数（Windows）进行数据转换
-
-我们先了解一下在 ETL/ELT（Extract, Transform, Load）过程中使用窗口函数进行数据转换的基本概念和常见使用场景。
-
-## 基本概念
-
-[窗口函数](window-function-summary.md)是SQL中专门用于在指定的数据集合（即“窗口”）中执行复杂多行操作的一类函数。窗口函数可以保留行级别详细信息，同时在特定数据窗口内部执行计算。
-
-[基本语法](windowframe.md)：
-
-```sql
-窗口函数() OVER (PARTITION BY column_name ORDER BY column_name)
-```
-
-* **OVER** 关键字定义了窗口的范围。
-
-* **PARTITION BY** 定义了如何划分数据分区，在每个分区内应用窗口函数。如果没有指定分区，则整个表被视为一个分区。
-
-* **函数** 应用于当前行的函数。函数结果在输出中添加一个额外的列。
-
-* **ORDER BY** 定义了窗口内的排序方式。
-
-## 常见窗口函数
-
-1. [RANK()](sql_functions/window_functions/rank.md)：排序函数，为每个分区的每个行分配一个排名。
-2. [DENSE\_RANK()](sql_functions/window_functions/dense_rank.md)：类似于 RANK()，但不会跳过排名。
-3. [ROW\_NUMBER()](sql_functions/window_functions/row_number.md)：为每个分区的行分配唯一编号。
-4. [SUM()](sql_functions/window_functions/sum.md)：累计求和。
-5. [AVG()](sql_functions/window_functions/avg.md)：计算平均。
-6. [LAG()](sql_functions/window_functions/lag.md)：向前获取某行的数据。
-7. [LEAD()](sql_functions/window_functions/lead.md)：向后获取某行的数据。
-
-## 使用场景
-
-### 1. 数据去重和标记
-
-窗口函数常用于数据去重，标记重复行。
-
-**前提条件**：表中需要有**唯一标识符**（如自增 ID、UUID 或业务主键），用于精确定位要删除的行。
-
-例如，我们可以使用窗口函数为每个分组编号，并删除第一个以外的重复行。
-
-```sql
-DELETE FROM table_name 
-WHERE id IN (
-    SELECT id FROM (
-        SELECT 
-            id,  -- 唯一标识符
-            ROW_NUMBER() OVER (
-                PARTITION BY column_field      -- 按此字段判断重复
-                ORDER BY identifier_field      -- 决定保留哪一条
-            ) AS rn
-        FROM table_name
-    ) WHERE rn > 1
-);
-```
-
-或者使用MERGE INTO方式，支持更复杂的匹配逻辑
-
-```sql
-MERGE INTO table_name t
-USING (
-    SELECT id FROM (
-        SELECT id, ROW_NUMBER() OVER (PARTITION BY column_field ORDER BY identifier_field) AS rn
-        FROM table_name
-    ) WHERE rn > 1
-) s
-ON t.id = s.id
-WHEN MATCHED THEN DELETE;
-```
-
-**注意**：窗口函数不能直接在 DELETE 的 WHERE 子句中使用，以下写法会报错：
-
-```sql
--- ❌ 错误写法
-DELETE FROM table_name
-WHERE ROW_NUMBER() OVER (PARTITION BY column_field ORDER BY identifier_field) > 1;
-```
-
-### 2. 数据分区和聚合
-
-窗口函数可以用于执行分区内的聚合操作，如累计求和和移动平均值。
-
-```sql
-SELECT 
-    product_id, 
-    order_date, 
-    SUM(order_amount) OVER (PARTITION BY product_id ORDER BY order_date) cumulative_sales 
-FROM orders;
-```
-
-### 3. 数据排序和排名
-
-通过窗口函数可以对数据进行排序和排名，并将结果用于后续计算。
-
-```sql
-SELECT 
-    customer_id, 
-    purchase_amount, 
-    RANK() OVER (PARTITION BY region ORDER BY purchase_amount DESC) purchase_rank 
-FROM purchases;
-```
-
-### 4. 数据补全与滞后/前瞻列
-
-利用 `LAG()` 和 `LEAD()` 函数，可以获取前/后行数据，用于补全缺损数据。
-
-```sql
-SELECT 
-    customer_id,
-    order_date,
-    order_amount,
-    LAG(order_amount) OVER (PARTITION BY customer_id ORDER BY order_date) previous_order_amount 
-FROM orders;
-```
-
-使用窗口函数进行 ETL 数据转换，可以有效地提高数据处理的灵活性和效率，使得复杂的数据分析和转换操作变得更加快捷和简洁。
-
-## 数据模型
-
-TPC-H 数据代表一个汽车零部件销售商的数据仓库，其中记录了订单、构成订单的项目（lineitem）、供应商、客户、销售的零部件（part）、地区、国家和零部件供应商（partsupp）。
-
-云器Lakehouse内置了共享的TPC-H数据，每个用户可以通过加上数据上下文直接使用，比如：
-
-```sql
-SELECT * FROM 
-clickzetta_sample_data.tpch_100g.customer
-LIMIT 10;
-```
-
-## 通过云器Lakehouse SQL窗口函数进行数据转换
-
-### 窗口函数有四个基本部分
-
-1. **分区**：根据指定列的值定义一组行。如果没有指定分区，则整个表被视为一个分区。
-2. **ORDER BY**：这个可选子句指定如何在分区内部对行进行排序。
-3. **函数**：应用于当前行的函数。函数结果在输出中添加一个额外的列。
-4. **窗口框架**：在分区内部，窗口框架允许你指定函数计算中要考虑的行。
-
-```sql
-SELECT
-  o_custkey,
-  o_orderdate,
-  o_totalprice,
-  SUM(o_totalprice) -- 函数 
-  OVER (
-    PARTITION BY
-      o_custkey -- 分区
-    ORDER BY
-      o_orderdate -- Order By；除非指定为 DESC，否则为升序
-  ) AS running_sum
-FROM
-  clickzetta_sample_data.tpch_100g.orders
-WHERE
-  o_custkey = 4
-ORDER BY
-  o_orderdate
-LIMIT
-  10;
-```
-
-函数 `SUM` 在上述查询中是一个聚合函数。注意 `running_sum` 如何在所有行上累加（即聚合）`o_totalprice`。行本身按其订单日期升序排列。
-
-**参考**：标准聚合函数是 `MIN, MAX, AVG, SUM, & COUNT`，现代数据系统提供了各种强大的聚合函数。请查阅你的数据库文档以了解可用的聚合函数。请 [阅读此文](agg_function.md) 了解 Lakehouse 中可用的聚合函数列表。
-
-## 使用排名函数获取前/后 n 行
-
-如果你正在处理一个需要获取前/后 n 行（根据某个值定义）的问题，那么使用 **行** 函数。
-
-让我们看看如何使用行函数的一个例子：
-
-从 `orders` 表中**获取每天消费最高的前 3 个客户**。`orders` 表的架构如下所示：
-
-```sql
-SELECT
-  *
-FROM
-  (
-    SELECT
-      o_orderdate,
-      o_totalprice,
-      o_custkey,
-      RANK() -- 排名函数 
-      OVER (
-        PARTITION BY
-          o_orderdate -- 按订单日期分区
-        ORDER BY
-          o_totalprice DESC -- 按总价格降序排列分区内的行
-      ) AS rnk
-    FROM
-      clickzetta_sample_data.tpch_100g.orders
-  )
-WHERE
-  rnk <= 3
-ORDER BY
-  o_orderdate
-LIMIT
-  5;
-```
-
-## 标准排名函数
-
-1. \`\`：在窗口框架内从 1 到 n 对行进行排名。对具有相同值（由 "ORDER BY" 子句定义）的行进行相同的排名，并跳过如果值不同则会存在的排名数字。
-2. \`\`：在窗口框架内从 1 到 n 对行进行排名。对具有相同值（由 "ORDER BY" 子句定义）的行进行相同的排名，并不跳过任何排名数字。
-3. \`\`：在窗口框架内从 1 到 n 添加行号，并不创建任何重复值。
-
-```sql
--- 让我们看看一个显示 RANK、DENSE_RANK 和 ROW_NUMBER 之间区别的例子
-SELECT 
-    order_date,
-    order_id,
-    total_price,
-    ROW_NUMBER() OVER (PARTITION BY order_date ORDER BY total_price) AS row_number,
-    RANK() OVER (PARTITION BY order_date ORDER BY total_price) AS rank,
-    DENSE_RANK() OVER (PARTITION BY order_date ORDER BY total_price) AS dense_rank
-FROM (
-    SELECT 
-        '2024-07-08' AS order_date, 'order_1' AS order_id, 100 AS total_price UNION ALL
-    SELECT 
-        '2024-07-08', 'order_2', 200 UNION ALL
-    SELECT 
-        '2024-07-08', 'order_3', 150 UNION ALL
-    SELECT 
-        '2024-07-08', 'order_4', 90 UNION ALL
-    SELECT 
-        '2024-07-08', 'order_5', 100 UNION ALL
-    SELECT 
-        '2024-07-08', 'order_6', 90 UNION ALL
-    SELECT 
-        '2024-07-08', 'order_7', 100 UNION ALL
-    SELECT 
-        '2024-07-10', 'order_8', 100 UNION ALL
-    SELECT 
-        '2024-07-10', 'order_9', 100 UNION ALL
-    SELECT 
-        '2024-07-10', 'order_10', 100 UNION ALL
-    SELECT 
-        '2024-07-11', 'order_11', 100
-) AS orders
-ORDER BY order_date, row_number;
-```

-
-现在我们已经看到了如何**使用窗口函数**以及如何使用**排名和聚合**函数。
-
-## 为什么在有分区的情况下定义窗口框架？
-
-虽然我们的函数在分区中的行上操作，但窗口框架提供了更精细的方式来操作分区中的一组选定行。
-
-当我们需要在一个分区中操作一组行（例如，滑动窗口）时，我们可以使用窗口框架来定义这些行。
-
-考虑一个场景，你有销售数据，你想计算每个商店的 3 天移动平均销售额：
-
-```sql
-SELECT
-    store_id,
-    sale_date,
-    sales_amount,
-    AVG(sales_amount) OVER (
-        PARTITION BY store_id
-        ORDER BY sale_date
-        ROWS BETWEEN 2 PRECEDING AND CURRENT ROW
-    ) AS moving_avg_sales
-FROM
-    sales;
-```
-
-在这个示例中：
-
-1. **PARTITION BY** store\_id 确保为每个商店分别进行计算。
-2. **ORDER BY** sale\_date 定义每个分区内部行的顺序。
-3. **ROWS BETWEEN 2 PRECEDING AND CURRENT ROW** 指定窗口框架，考虑当前行和前两行来计算移动平均值。
-
-如果没有定义窗口框架，函数可能无法提供你需要的具体移动平均值计算。
-
-## 使用 ROWS 定义窗口框架
-
-**ROWS**：用于根据位置选择与当前行相关的行集。
-
-1. 行定义格式 `ROWS BETWEEN start_point AND end_point`。
-
-   2. start\_point 和 end\_point 可以是以下三个中的任意一个（按正确顺序）：
-
-      1. **n PRECEDING**：当前行前 n 行。UNBOUNDED PRECEDING 表示当前行之前的所有行。
-      2. **n FOLLOWING**：当前行后 n 行。UNBOUNDED FOLLOWING 表示当前行之后的所有行。
-
-让我们看看如何使用相对行号来定义窗口范围。
-
-考虑这个窗口函数：
-
-```sql
-AVG(total_price) OVER ( -- 函数：运行平均值
-    PARTITION BY o_custkey -- 按客户分区
-    ORDER BY order_month 
-    ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING -- 窗口框架定义为 1 行前到 1 行后
-    )
-```
-
-编写一个SQL查询，从 orders 表中获取以下输出：
-
-1. 1. o\_custkey
-   2. order\_month：格式为 YYYY-MM，使用 strftime(o\_orderdate, '%Y-%m') AS order\_month
-   3. total\_price：该月的 o\_totalprice 总和
-   4. three\_mo\_total\_price\_avg：该客户过去、当前和下一个月的 total\_price 平均值
-
-```sql
-SELECT
-  order_month,
-  o_custkey,
-  total_price,
-  ROUND(
-    AVG(total_price) OVER ( -- 函数：运行平均值
-      PARTITION BY
-        o_custkey -- 按客户分区
-      ORDER BY
-        order_month ROWS BETWEEN 1 PRECEDING
-        AND 1 FOLLOWING -- 窗口框架定义为 1 行前到 1 行后
-    ),
-    2
-  ) AS three_mo_total_price_avg
-FROM
-  (
-    SELECT
-      date_format (o_orderdate, 'yyyy-MM') AS order_month,
-      o_custkey,
-      SUM(o_totalprice) AS total_price
-    FROM
-      clickzetta_sample_data.tpch_100g.orders
-    GROUP BY
-      1,
-      2
-  )
-LIMIT
-  5;
-```
-
-## 使用 RANGE 定义窗口框架
-
-1. **RANGE**：用于根据 `ORDER BY` 子句中指定的列的值选择与当前行相关的行集。
-
-   1. 范围定义格式 `RANGE BETWEEN start_point AND end_point`。
-
-   2. start\_point 和 end\_point 可以是以下任意一个：
-
-      1. **CURRENT ROW**：当前行。
-      2. **n PRECEDING**：所有值在指定范围内且小于或等于当前行值的 n 个单位之前的行。
-      3. **n FOLLOWING**：所有值在指定范围内且大于或等于当前行值的 n 个单位之后的行。
-      4. **UNBOUNDED PRECEDING**：分区中当前行之前的所有行。
-      5. **UNBOUNDED FOLLOWING**：分区中当前行之后的所有行。
-
-   3. `RANGE` 在处理数值或日期/时间范围时特别有用，允许进行如运行总计、移动平均值或累积分布等计算。
-
-让我们看看 `RANGE` 如何与 `AVG(total price) OVER (PARTITION BY customer id ORDER BY date RANGE BETWEEN INTERVAL '1' DAY PRECEDING AND '1' DAY FOLLOWING)` 一起工作。
-
-现在我们已经看到了如何使用 ROWS 创建窗口框架，让我们探索如何使用 RANGE 来做这件事。
-
-1. 编写一个查询，从 orders 表中获取以下输出：
-
-   1. order\_month，
-   2. o\_custkey，
-   3. total\_price，
-   4. three\_mo\_total\_price\_avg
-   5. **consecutive\_three\_mo\_total\_price\_avg**：该客户的连续 3 个月 total\_price 平均值。注意，这应该只包括按时间顺序排列的月份。
-
-```sql
-SELECT
-  order_month,
-  o_custkey,
-  total_price,
-  ROUND(
-    AVG(total_price) OVER (
-      PARTITION BY
-        o_custkey
-      ORDER BY
-        CAST(order_month AS DATE) RANGE BETWEEN INTERVAL '1' MONTH PRECEDING
-        AND INTERVAL '1' MONTH FOLLOWING
-    ),
-    2
-  ) AS consecutive_three_mo_total_price_avg,
-  ROUND(
-    AVG(total_price) OVER (
-      PARTITION BY
-        o_custkey
-      ORDER BY
-        order_month ROWS BETWEEN 1 PRECEDING
-        AND 1 FOLLOWING
-    ),
-    2
-  ) AS three_mo_total_price_avg
-FROM
-  (
-    SELECT
-      date_format (o_orderdate, 'yyyy-mm-01') AS order_month,
-      o_custkey,
-      SUM(o_totalprice) AS total_price
-    FROM
-      clickzetta_sample_data.tpch_100g.orders
-    GROUP BY
-      1,
-      2
-  )
-ORDER BY
-  o_custkey,
-  order_month
-LIMIT
-  50;
-```

-
-## 回顾
-
-1. 使用窗口函数时：
-
-   * 计算运行指标（类似于 `GROUP BY`，但保留所有行）
-   * 根据特定列对行进行排名
-   * 从当前行访问其他行的值
-
-2. 窗口有四个关键部分：分区、Order By、函数、窗口框架
-
-3. 使用 ROWS 或 RANGE 定义窗口框架
-
-4. 窗口函数成本较高；注意性能

-### 函数名称：approx_count_distinct
-
-```
-approx_count_distinct(expr)
-```
-
-#### 功能描述
-`approx_count_distinct` 函数采用 `hyperloglog` 算法来近似计算指定列中不同值的数量。当数据集较大时，该函数能够在保证较高性能的同时，得到一个近似的基数估计。需要注意的是，该函数在计算过程中会存在一定的误差。
-
-#### 参数说明
-* `expr`: 需要计算基数的列名，可以是数值类型、浮点类型、字符串类型、时间类型、布尔类型、`DECIMAL`、`BINARY` 等基本数据类型。`expr` 可以是单个列名，也可以是表达式或函数的组合。
-
-#### 返回结果
-* 返回值类型为 `BIGINT` 类型，表示近似计算出的基数。
-* 如果 `expr` 中包含 `NULL` 值，这些值将不会被计算在内。
-
-#### 使用示例
-
-**示例 1：**
-```sql
-SELECT approx_count_distinct(col) FROM VALUES (1), (1), (2), (2), (3), (NULL) AS tab(col);
-+-----------------------------+
-| approx_count_distinct(col)  |
-+-----------------------------+
-| 3                           |
-+-----------------------------+
-```
-
-**示例 2：**
-假设我们有一个名为 `sales` 的表，其中包含以下列：`product_id`（产品ID）、`sale_date`（销售日期）和 `quantity`（数量）。我们想要计算在过去一个月内销售的不同产品的数量，可以使用以下查询：
-```sql
-SELECT approx_count_distinct(product_id)
-FROM sales
-WHERE sale_date >= NOW() - INTERVAL '1 MONTH';
-```
-这将返回过去一个月内销售的不同产品数量的近似值。
-
-**示例 3：**
-如果我们想要计算某个特定类别下销售的不同产品数量，可以结合使用 `approx_count_distinct` 函数和其他条件，如下所示：
-```sql
-SELECT approx_count_distinct(product_id)
-FROM sales
-WHERE category = 'Electronics' AND sale_date >= NOW() - INTERVAL '1 MONTH';
-```
-这将返回过去一个月内在电子产品类别下销售的不同产品数量的近似值。

-### 近似直方图函数（APPROX_HISTOGRAM）
-
-#### 功能描述
-
-`approx_histogram` 函数用于根据给定的数值型列 `col` 和直方图的桶数 `n`，生成一个近似的直方图。该函数返回一个数组，数组中的每个元素是一个结构体（`STRUCT`），包含三个字段：最小值（`min`）、最大值（`max`）和计数（`count`）。该函数在统计数据分布时非常有用，尤其是在处理大量数据时，可以快速了解数据的分布情况。
-
-#### 参数说明
-
-* `col`：需要生成直方图的数值型列。
-* `n`：直方图的桶数，必须是一个大于 0 的整数常量。
-
-#### 返回结果
-
-函数返回一个结构体数组，每个结构体（代表一个桶）包含三个字段：
-
-* `min`：直方图桶的最小值。
-* `max`：直方图桶的最大值。
-* `count`：落在该桶内的数据数量。
-
-#### 使用示例
-
-以下示例展示了如何使用 `approx_histogram` 函数生成不同桶数的直方图。
-
-**示例 1：生成 2 个桶的直方图**
-
-```sql
-SELECT approx_histogram(col, 2) FROM VALUES (0), (1), (2), (3), (4) AS t(col);

-### 近似百分位数函数：APPROX_PERCENTILE
-
-#### 功能描述
-
-`APPROX_PERCENTILE` 函数用于计算并返回指定列中数值的近似百分位数。该函数接受两个参数：第一个参数是需要计算百分位数的列名，第二个参数是表示所需百分位数的浮点数。当数据按照升序排列时，该函数返回对应于指定百分位数的数值。
-
-#### 参数说明
-
-1. `col`: 需要计算百分位数的列名。该列应包含数值类型的数据，如 `TINYINT`、`SMALLINT`、`INT`、`BIGINT`、`FLOAT`、`DOUBLE` 或 `DECIMAL`。
-2. `percentage`: 一个 `DOUBLE` 类型的常量，表示所需计算的百分位数。该值应在 [0.0, 1.0] 区间内。
-
-#### 返回结果
-
-函数返回值为 `DOUBLE` 类型。如果指定了 `DISTINCT` 关键字，则计算结果将基于去重后的数据集进行。需要注意的是，`NULL` 值不会参与计算。
-
-#### 使用示例
-
-1. 计算数据集的中位数（50%分位数）：
-
-```sql
-SELECT approx_percentile(col, 0.5) FROM VALUES (0), (6), (6), (7), (9), (10) AS tab(col);
-+-------------------------------+
-| approx_percentile(col, 0.5BD) |
-+-------------------------------+
-| 6.25                          |
-+-------------------------------+
-```
-
-2. 计算去重后数据集的中位数（50%分位数）：
-
-```sql
-SELECT approx_percentile(DISTINCT col, 0.5)
-FROM VALUES (0), (6), (6), (7), (9), (10) AS tab(col);
-+----------------------------------------+
-| approx_percentile(DISTINCT col, 0.5BD) |
-+----------------------------------------+
-| 7.0                                    |
-+----------------------------------------+
-```
-
-3. 计算数据集的 25% 分位数：
-
-```sql
-SELECT approx_percentile(col, 0.25) FROM VALUES (0), (6), (6), (7), (9), (10) AS tab(col);
-+--------------------------------+
-| approx_percentile(col, 0.25BD) |
-+--------------------------------+
-| 6.0                            |
-+--------------------------------+
-```
-
-4. 计算数据集的 75% 分位数：
-
-```sql
-SELECT approx_percentile(col, 0.75) FROM VALUES (0), (6), (6), (7), (9), (10) AS tab(col);
-+--------------------------------+
-| approx_percentile(col, 0.75BD) |
-+--------------------------------+
-| 9.0                            |
-+--------------------------------+
-```
-
-### 总结
-
-`APPROX_PERCENTILE` 函数为用户提供了一种快速计算数据集近似百分位数的方法。通过调整 `percentage` 参数，用户可以轻松获取不同百分位数的数值，从而更好地分析和理解数据。在使用该函数时，请注意确保数据类型匹配，并且 `percentage` 参数值在有效范围内。

-### 函数名称：approx_top_k
-
-```sql
-approx_top_k(col, k, [maxItemsTracked])
-```
-
-#### 功能描述
-
-该函数用于从指定列（`col`）中提取出现频率最高的前 `k` 个项目值，并返回它们的近似计数。这是一个基于概率的数据结构实现，因此结果可能会有一定的误差，但在大多数情况下，它能有效地反映数据的分布情况。
-
-#### 参数说明
-
-* `col`: 输入列，可以是数值类型、字符串类型或嵌套类型。
-* `k`: 需要返回的前 `k` 个最常出现项的数目，需为大于 0 的整数值。
-* `maxItemsTracked`: 可选参数，用于指定跟踪的最大项目数。默认值为 10000。如果指定的 `maxItemsTracked` 大于或等于 `k`，则使用指定值；否则，将使用 `k` 作为跟踪的最大项目数。
-
-#### 返回结果
-
-函数返回一个结构化数组，每个元素为一个结构体，包含三个字段：`item`（原始输入类型的值）、`count`（长整型，表示该项出现的近似次数）和 `approximation`（布尔值，表示结果是否为近似值，始终为 `true`）。数组按照 `count` 字段降序排列。
-
-#### 使用示例
-
-以下示例展示了如何使用 `approx_top_k` 函数来获取数据中最常见的项目及其出现次数。
-
-**示例 1**：
-
-```sql
-SELECT approx_top_k(col, 1) FROM VALUES (7), (7), (6), (9), (8), (7) AS tab(col);
-+-------------------------+
-|  approx_top_k(col, 1)   |
-+-------------------------+
-| [{"value":7,"count":3}] |
-+-------------------------+
-```
-
-**示例 2**：
-
-```sql
-SELECT approx_top_k(col, 2, 100) FROM VALUES (7), (6), (6), (7), (9), (8), (7) AS tab(col);
-+-----------------------------------------------+
-|           approx_top_k(col, 2, 100)           |
-+-----------------------------------------------+
-| [{"value":7,"count":3},{"value":6,"count":2}] |
-+-----------------------------------------------+
-```
-
-**示例 3**：
-
-```sql
-SELECT approx_top_k(col, 3)
-FROM VALUES ('apple'), ('banana'), ('apple'), ('orange'), ('banana'), ('apple') AS tab(col);
-+-----------------------------------------------------------------------------------------+
-|                                  approx_top_k(col, 3)                                   |
-+-----------------------------------------------------------------------------------------+
-| [{"value":"apple","count":3},{"value":"banana","count":2},{"value":"orange","count":1}] |
-+-----------------------------------------------------------------------------------------+
-```
-
-**注意**：
-
-* 由于 `approx_top_k` 函数是基于概率的，因此返回的结果可能会有一定的误差。在实际应用中，可以通过调整 `maxItemsTracked` 参数来平衡精度和性能。
-* 当处理大量数据时，为了提高性能，可以适当降低 `maxItemsTracked` 的值。但请注意，这可能会影响结果的准确性。

-
-```
-collect_list([DISTINCT] expr [, limit]) [FILTER (WHERE condition)]
-```
-
-#### 功能描述
-
-`collect_list` 函数用于从输入的一组数据中收集并返回一个数组。用户可以选择性地使用 `DISTINCT` 关键字来返回一个不包含重复元素的数组。
-
-#### 参数说明
-
-* `expr`：任意类型的表达式，用于从输入数据中收集元素。
-* `limit`：可选参数，整数类型，表示最多收集的元素个数。如果不指定，则收集所有元素。
-
-#### 返回结果
-
-* 返回一个数组，数组中的元素类型与输入参数类型相同。
-* 如果设置了 `DISTINCT` 关键字，则返回一个去重后的数组。
-* 如果指定了 `limit` 参数，则返回的数组最多包含 `limit` 个元素。
-* 函数不保证返回结果中元素的顺序。
-* 如果输入数据包含 `NULL` 值，则这些值不会被包含在返回的数组中。

-### 收集集合函数：COLLECT_SET
-
-```
-collect_set([DISTINCT] expr [, limit]) [FILTER (WHERE condition)]
-```
-
-#### 功能描述
-
-`collect_set` 函数用于从输入的一组数据中收集并返回一个不重复的元素集合。该函数可以确保返回的数组中不包含重复的元素，从而使结果更加简洁明了。当指定 `DISTINCT` 关键字时，函数会对结果进行去重处理，但请注意，即使不指定 `DISTINCT`，`collect_set` 函数也会进行去重操作，因此 `DISTINCT` 关键字在此场景下不影响结果。
-
-#### 参数说明
-
-* `expr`：可以是任意数据类型的表达式。
-* `limit`：可选参数，整数类型，表示最多收集的元素个数。如果不指定，则收集所有元素。
-
-#### 返回结果
-
-* 返回一个数组（`ARRAY`），数组中的元素类型与输入参数类型相同。
-* 即使使用 `DISTINCT` 关键字，也不会影响去重结果。
-* 如果指定了 `limit` 参数，则返回的数组最多包含 `limit` 个元素。
-* 返回的数组元素顺序不保证与输入顺序相同。
-* 输入的 `NULL` 值不会包含在结果数组中。
-
-#### 使用示例

-| collect_set(DISTINCT col) |
-+---------------------------+
-| ["c","b","a"]             |
-+---------------------------+
-```
-
-**示例 3：使用 FILTER 子句条件性地收集集合**
-
-```sql
-SELECT collect_set(col) FILTER (WHERE col > 1) FROM VALUES (1), (2), (3), (2), (4) AS tab(col);
-+-------------------------------------------+
-| collect_set(col) FILTER (WHERE (col > 1)) |
-+-------------------------------------------+
-| [4,3,2]                                   |
-+-------------------------------------------+
-```
-
-**示例 4：结合 FILTER 子句和 DISTINCT 收集条件集合**
-
-```sql
-SELECT collect_set(DISTINCT col) FILTER (WHERE col != 'a') FROM VALUES ('a'), ('b'), ('c'), ('b') AS tab(col);
-+----------------------------------------------------------+
-| collect_set(DISTINCT col) FILTER (WHERE (NOT (col = 'a')))|
-+----------------------------------------------------------+
-| ["c","b"]                                                |

-| collect_set(col, 2) |
-+---------------------+
-| [2,1]               |
-+---------------------+
-```
-
-#### 注意事项
-

-### COUNT 函数
-
-#### 简介
-
-`COUNT` 函数用于返回一组数据的行数。它可以统计所有行的数量，也可以统计指定列中非 `NULL` 值的数量，或者统计指定列中不同值的数量。
-
-#### 语法
-
-```sql
-COUNT(*) [FILTER (WHERE condition)]
-COUNT([DISTINCT] expr1[, expr2, ...]) [FILTER (WHERE condition)]
-```
-
-#### 参数
-
-* `exprN`: 任意类型的表达式。
-
-#### 返回结果
-
-* 返回值类型为 `BIGINT` 类型。
-* 使用 `COUNT(*)` 形式时，所有行都会计入总数，包括包含 `NULL` 值的行。
-* 使用 `COUNT(expr1[, expr2, ...])` 形式时，如果某一行的任意列为 `NULL`，该行将被忽略。
-* 使用 `COUNT(DISTINCT expr1[, expr2, ...])` 形式时，首先对指定列进行去重，然后统计非 `NULL` 值的数量。
-
-#### 示例
-
-1. 统计所有行的数量（包括包含 `NULL` 值的行）：
-```sql
-SELECT COUNT(*) FROM VALUES (NULL), (1), (3), (4) AS tab(col);
-+----------+
-| count(1) |
-+----------+
-| 4        |
-+----------+
-```
-
-2. 统计指定列中非 `NULL` 值的数量：
-```sql
-SELECT COUNT(a, b) FROM VALUES (NULL, NULL), (1, NULL), (NULL, 3), (4, 5) AS tab(a, b);
-+------------+
-| count(a,b) |
-+------------+
-| 1          |
-+------------+
-```
-
-3. 统计指定列中不同值的数量（忽略 `NULL` 值）：
-```sql
-SELECT COUNT(DISTINCT a, b)
-FROM VALUES (1, NULL), (1, NULL), (4, 5), (4, 5), (1, 2) AS tab(a, b);
-+-----------------------+
-| count(DISTINCT a, b)  |
-+-----------------------+
-| 2                     |
-+-----------------------+
-```
-
-4. 统计某一列中特定值的数量：
-```sql
-SELECT COUNT(*) FROM customers WHERE status = 'active';
-+----------+
-| count(1) |
-+----------+
-| 150      |
-+----------+
-```
-
-5. 统计销售记录中不同产品的销售数量（忽略 `NULL` 值）：
-```sql
-SELECT COUNT(DISTINCT product_id) FROM sales_records;
-+------------------------------+
-| count(DISTINCT `product_id`) |
-+------------------------------+
-| 50                           |
-+------------------------------+
-```
-
-6. 使用 FILTER 子句条件性地统计行数：
-```sql
-SELECT COUNT(*) FILTER (WHERE col > 2) FROM VALUES (1), (2), (3), (4), (NULL) AS tab(col);
-+--------------------------------------+
-| count(1) FILTER (WHERE (col > 2))    |
-+--------------------------------------+
-| 2                                    |
-+--------------------------------------+
-```
-
-7. 结合 FILTER 子句和 DISTINCT 统计不同值的数量：
-```sql
-SELECT COUNT(DISTINCT a) FILTER (WHERE b > 1) FROM VALUES (1, 1), (1, 2), (2, 2), (3, 1) AS tab(a, b);
-+------------------------------------------------------+
-| count(DISTINCT a) FILTER (WHERE (b > 1))             |
-+------------------------------------------------------+
-| 2                                                    |

-### COUNT_DISTINCT 函数
-
-```
-count_distinct(expr)
-```
-
-#### 功能描述
-
-`COUNT_DISTINCT` 函数用于计算指定列中不同值（去重后）的数量。这是一个聚合函数，等价于 `COUNT(DISTINCT expr)`，但在某些场景下优化器可能会做特殊优化。
-
-#### 参数说明
-
-* `expr`：任意类型的表达式，要计算其不同值的数量。
-
-#### 返回类型
-
-* 返回 `BIGINT` 类型（非空）。
-* 返回不同值的数量。
-
-#### 注意事项
-
-* 函数计算过程中，`NULL` 值会被忽略，不计入结果。
-* 如果所有值都是 `NULL`，返回 0。
-* 如果输入为空集，返回 0。
-* `COUNT_DISTINCT` 需要维护所有不同值的集合，内存开销较大。对于大数据集，如果只需要近似值，考虑使用 `APPROX_COUNT_DISTINCT`。
-
-#### 使用示例
-
-1. 基本用法：计算不同值的数量
-
-```sql
-SELECT count_distinct(city)
-FROM VALUES ('Beijing'), ('Shanghai'), ('Beijing'), ('Shenzhen') AS t(city);
-+------------------------+
-| count_distinct(city)   |
-+------------------------+
-| 3                      |
-+------------------------+
-```
-
-2. 等价于 COUNT(DISTINCT ...)
-
-```sql
-SELECT count_distinct(city), COUNT(DISTINCT city)
-FROM VALUES ('Beijing'), ('Shanghai'), ('Beijing'), ('Shenzhen') AS t(city);
-+------------------------+----------------------+

-### COUNT_IF 函数
-
-#### 功能描述
-
-`COUNT_IF` 函数用于计算表达式中值为 `TRUE` 的行数。该函数可以处理任意返回布尔值的表达式，并返回一个 `BIGINT` 类型的数值结果。需要注意的是，`NULL` 值不会影响计数结果。
-
-#### 语法格式
-
-```sql
-COUNT_IF([DISTINCT] expr1)
-```
-
-#### 参数说明
-
-* `expr1`: 需要计算的布尔表达式。返回值为 `TRUE` 或 `FALSE` 的任意表达式。
-
-#### 返回结果
-
-* 返回值为 `BIGINT` 类型，表示表达式为 `TRUE` 的行数。
-* 如果使用 `DISTINCT` 关键字，则只计算不同的 `TRUE` 值，重复的 `TRUE` 值只计算一次。
-
-#### 使用示例
-
-**示例 1**：计算不同的 `TRUE` 值数量
-
-```sql
-SELECT count_if(col % 2 = 0) FROM VALUES (NULL), (0), (1), (2), (2), (3) AS tab(col);
-+-----------------------+
-| count_if(col % 2 = 0) |
-+-----------------------+
-| 3                     |
-+-----------------------+
-```
-
-**示例 2**：结合 `DISTINCT` 使用
-
-```sql
-SELECT count_if(DISTINCT col % 2 = 0)
-FROM VALUES (NULL), (0), (1), (2), (2), (3) AS tab(col);
-+--------------------------------+
-| count_if(DISTINCT col % 2 = 0) |
-+--------------------------------+
-| 1                              |
-+--------------------------------+
-```
-
-**示例 3**：计算 `NULL` 值的数量
-
-```sql
-SELECT count_if(col IS NULL) FROM VALUES (NULL), (0), (1), (2), (3) AS tab(col);
-+-------------------------+
-| count_if((col) IS NULL) |
-+-------------------------+
-| 1                       |
-+-------------------------+
-```
-
-#### 注意事项
-
-* `COUNT_IF` 函数仅适用于返回布尔值的表达式。
-* 使用 `DISTINCT` 关键字时，确保表达式返回的值可以用于区分重复的 `TRUE` 值。
-* `NULL` 值不会影响计数结果。

-### COVAR_POP 函数
-
-```
-covar_pop(y, x)
-```
-
-#### 功能描述
-
-`COVAR_POP` 函数用于计算两个数值列之间的总体协方差（Population Covariance）。协方差衡量两个变量共同变化的程度，是衡量变量相关性的统计量。
-
-#### 参数说明
-
-* `y`：数值类型的表达式，作为因变量。必须是可以转换为 `DOUBLE` 的数值类型。
-* `x`：数值类型的表达式，作为自变量。必须是可以转换为 `DOUBLE` 的数值类型。
-
-#### 返回类型
-
-* 返回 `DOUBLE` 类型的总体协方差值。
-  * 正值：x 和 y 倾向于同向变化（正相关）
-  * 负值：x 和 y 倾向于反向变化（负相关）
-  * 接近 0：变量之间相关性较弱
-
-#### 注意事项
-
-* 函数计算过程中，`NULL` 值会被忽略。
-* 如果有效数据点少于 1 个，返回 `NULL`。
-* 总体协方差使用除以 n 的公式计算，而样本协方差使用除以 (n-1) 的公式，因此总体协方差通常小于样本协方差。

-# GROUP_BITMAP 函数
-
-## 简介
-
-`GROUP_BITMAP` 函数是一个聚合函数，用于对一组无符号整数值进行聚合，计算出对应的 Bitmap（位图）数据结构。该函数在处理大规模数据集时非常高效，尤其适用于需要对大量整数值进行集合操作（如并集、交集等）的场景。
-
-## 语法
-
-```sql
-group_bitmap(value)
-```
-
-## 参数
-
-* `value`：`INTEGER` 或 `BIGINT` 类型的表达式，表示需要聚合的整数值。通常，这些值是从数据表的某一列中提取的。
-
-## 返回值
-
-返回一个 `INT` 类型的结果，表示聚合后的位图。`Bitmap` 是一种紧凑的数据结构，通过位表示法存储整数值的存在性。每个位对应一个整数值，如果该位为 1，则表示对应的整数值存在于集合中；如果该位为 0，则表示对应的整数值不存在于集合中。
-
-## 使用示例
-
-示例 1：基本用法
-
-```sql
-SELECT group_bitmap(v) AS bitmap_result
-FROM VALUES (1), (2), (3), (4), (5) AS t(v);
-+---------------+
-| bitmap_result |
-+---------------+
-| 5             |
-+---------------+
-```
-
-**结果**：
-返回一个 `INT` 类型的位图。
-
-## 注意事项
-
-1. **输入值范围**：`group_bitmap` 函数适用于无符号整数值。如果输入值为负数，可能会导致意外的结果或错误。
-2. **性能优化**：在处理大规模数据集时，`group_bitmap` 函数非常高效。但如果数据量过大，仍需注意性能影响。在可能的情况下，可尝试优化输入数据以提高函数执行效率。
-3. **中间状态的使用**：如果需要对多个分组进行聚合操作，建议使用 `group_bitmap_state` 和 `group_bitmap_merge` 函数，以避免重复计算。

-### GROUP_BITMAP_MERGE_STATE 函数
-
-#### 功能描述
-`GROUP_BITMAP_MERGE_STATE` 函数用于对多个位图（`bitmap`）值进行合并操作，合并这些值并返回它们的并集。该函数特别适用于处理分类数据，能够高效地合并具有相同分类的位图表示，从而得到一个包含所有类别元素的位图。
-
-#### 参数说明
-- **`bitmap`**：输入参数，类型为位图（`BITMAP`）。指需要进行逻辑“或”操作的位图列的值。
-
-#### 返回结果
-函数返回一个位图类型的值，该值包含了输入参数中所有位图值的并集。
-
-#### 使用示例
-以下示例展示了如何使用 `GROUP_BITMAP_MERGE_STATE` 函数来计算位图的逻辑“或”运算结果，并进一步计算其基数（`cardinality`）：
-
-```sql
-SELECT c, bitmap_cardinality(GROUP_BITMAP_MERGE_STATE(bitmap_build(v))) AS b
-FROM (
-  VALUES ('a', ARRAY(1)), ('a', ARRAY(2)), ('a', ARRAY(2)), ('b', ARRAY(3)), ('b', NULL)
-) AS t(c, v)
-GROUP BY c;
-+---+---+
-| c | b |
-+---+---+
-| a | 2 |
-| b | 1 |
-+---+---+
-```
-
-在这个查询中，我们创建了一个包含分类 `c` 和与之对应的位图值 `v` 的表。然后，我们使用 `GROUP_BITMAP_MERGE_STATE` 函数对每个分类下的位图值进行合并。对于分类 `a`，合并后的位图包含了 `[1, 2]`；对于分类 `b`，合并后的位图包含了 `[3]`。最终，查询结果将显示每个分类的合并位图的基数。

-### GROUP_BITMAP_STATE 函数
-
-#### 功能描述
-`GROUP_BITMAP_STATE` 函数用于根据输入的表达式（`expr`）构建一个 `BITMAP` 类型的结果。该函数通常用于对整数类型的数据进行分组操作，并将每个分组的唯一值转换为一个 `bitmap` 数组。
-
-#### 参数说明
-- `expr`：待处理的整数类型表达式。
-
-#### 返回类型
-- 返回一个 `BITMAP` 类型的结果。
-
-#### 使用示例
-以下是一个使用 `group_bitmap_state` 函数的示例。我们有一个包含两列的数据表，分别为 `c` 和 `v`。我们希望根据 `c` 列的值进行分组，并将 `v` 列中每个分组的唯一值转换为一个 `bitmap` 数组。
-
-```sql
-SELECT c, bitmap_to_array(group_bitmap_state(v)) AS bitmap_array
-FROM VALUES ('a', 1), ('a', 2), ('a', 2), ('b', 3) AS v(c, v)
-GROUP BY c;

-+----+--------------+
-| a  | [1,2]        |
-| b  | [3]          |
-+----+--------------+
-```
-
-在这个示例中，我们可以看到 `a` 分组包含两个唯一值 1 和 2，因此返回的 `bitmap` 数组为 `[1,2]`。而 `b` 分组只包含一个唯一值 3，所以返回的 `bitmap` 数组为 `[3]`。

-#### 简介
-
-`group_concat` 函数用于将一组字符串值连接成一个单一的字符串。当处理多个行或记录时，此函数非常有用，可以将来自同一组的结果合并为一个字符串，通常用于报表生成和数据汇总场景。
-
-#### 语法
-
-```sql
-group_concat(expression [SEPARATOR sep_string]) [FILTER (WHERE condition)]
-```
-
-#### 参数
-
-* `expression`: 要连接的列或表达式。
-* `sep_string`: （可选）用作分隔符的字符串。如果省略，`Lakehouse` 默认使用逗号（`,`）作为分隔符。
-
-#### 返回结果
-
-* 返回一个字符串，其中包含连接后的所有非 `NULL` 值，值之间由指定的分隔符分隔。
-
-#### 使用示例
-
-1. 基本使用：
-
-```sql
-SELECT a, group_concat(b SEPARATOR "-")
-FROM VALUES ('A1', 2), ('A1', 1), ('A2', 3), ('A1', 1) AS tab(a, b)
-GROUP BY a;
-+----+-------------------+
-| a  | WM_CONCAT('-', b) |
-+----+-------------------+
-| A2 | 3                 |
-| A1 | 2-1-1             |
-+----+-------------------+
-```
-
-2. 使用 FILTER 子句条件性地连接字符串：
-
-```sql
-SELECT a, group_concat(b SEPARATOR "-") FILTER (WHERE b > 1)
-FROM VALUES ('A1', 2), ('A1', 1), ('A2', 3), ('A1', 3) AS tab(a, b)
-GROUP BY a;
-+----+----------------------------------------------------+
-| a  | WM_CONCAT('-', b) FILTER (WHERE (b > 1))           |
-+----+----------------------------------------------------+
-| A2 | 3                                                  |
-| A1 | 2-3                                                |
-+----+----------------------------------------------------+
-```
-
-#### 注意事项
-
-* 如果结果字符串超过系统设定的最大长度限制，`group_concat` 可能会报错。在 `Lakehouse` 中，可以通过设置表属性 `cz.storage.write.max.string.bytes` 系统变量来调整这个限制。
-* 在使用 `group_concat` 函数时，应注意 `NULL` 值会被忽略，不会包含在最终的字符串中。

-返回一个字符串类型的值，其中包含连接后的结果。如果设置了`DISTINCT`关键字,则计算去重后的集合；否则,保留所有值。`NULL`值不参与计算。
-
-#### 使用示例
-
-1. 使用&&拼接
-
-```sql
-SELECT wm_concat('&&', col) FROM VALUES ('row1'), (NULL), ('row3') AS t(col);
-+----------------------+
-| wm_concat('&&', col) |
-+----------------------+
-| row1&&row3           |
-+----------------------+
-```
-
-2. 带分隔符的连接：
-
-```sql
-SELECT wm_concat(',', col) FROM VALUES (1), (NULL), (3) AS t(col);
-+---------------------+
-| wm_concat(',', col) |
-+---------------------+
-| 1,3                 |
-+---------------------+
-```
-
-3. 去重连接并分组：
-
-```sql
-SELECT k, wm_concat(DISTINCT '|', v)
-FROM VALUES
-(1, 'ALLEN'),
-(1, NULL),
-(1, 'ALLEN'),
-(2, 'KING'),
-(2, 'ALEX') AS t(k, v) GROUP BY k;
-+---+----------------------------+
-| k | wm_concat(DISTINCT '|', v) |
-+---+----------------------------+
-| 1 | ALLEN                      |
-| 2 | KING|ALEX                  |
-+---+----------------------------+
-```
-
-4. 连接时处理空格和特殊字符：
-
-```sql
-SELECT wm_concat(' - ', col) FROM VALUES ('John Doe'), ('Jane Smith'), (NULL), ('Alice Jones') AS t(col);
-+-------------------------------------+
-|        wm_concat(' - ', col)        |
-+-------------------------------------+
-| John Doe - Jane Smith - Alice Jones |
-+-------------------------------------+
-```
-
-#### 注意事项
-
-* 当`col`列中的值为`NULL`时,`WM_CONCAT`函数不会将其包含在结果中。
-* 如果需要连接的列中包含空格或特殊字符，请确保使用适当的分隔符以避免歧义。
-* 使用`DISTINCT`关键字可以有效地去除重复的字符串值,但请注意,这可能会影响性能。在处理大量数据时,请谨慎使用此选项。

-### BITMAP_AND_CARDINALITY 函数
-
-#### 概述
-`BITMAP_AND_CARDINALITY` 函数用于计算两个 bitmap 类型参数的集合交集，并返回结果集中的元素数量。该函数在处理大量数据时具有较高的性能优势，特别适用于需要快速计算集合关系的场景。
-
-#### 语法
-```
-bitmap_and_cardinality(left, right)
-```
-#### 参数说明
-
-* `left` (bitmap 类型): 第一个输入的 bitmap 数据。
-* `right` (bitmap 类型): 第二个输入的 bitmap 数据。
-
-#### 返回结果
-返回一个 bigint 类型的值，表示两个输入 bitmap 交集中的元素数量。
-
-#### 使用示例
-
-**示例 1**：计算两个简单 bitmap 的交集元素数量
-```sql
-SELECT bitmap_and_cardinality(bitmap_build(array(1, 2, 3)), bitmap_build(array(2, 3, 4)));
-```
-结果：
-```
-2
-```
-在这个例子中，两个 bitmap 分别为 `{1, 2, 3}` 和 `{2, 3, 4}`，它们的交集为 `{2, 3}`，因此结果为 2。
-
-**示例 2**：结合实际数据表计算交集元素数量
-假设我们有一个名为 `users` 的数据表，其中包含以下列：`id`, `username`, `interests`。`interests` 列存储了用户的兴趣爱好，数据类型为 bitmap。
-
-现在，我们想要计算喜欢“篮球”和“足球”的用户数量。可以使用以下 SQL 查询实现：
-```sql
-SELECT bitmap_and_cardinality(
-    bitmap_or(
-        bitmap_and(interests, 'basketball'),
-        bitmap_and(interests, 'football')
-    ),
-    interests
-) AS shared_interests_count
-FROM users;
-```
-在这个例子中，我们首先使用 `bitmap_and` 函数筛选出喜欢“篮球”和“足球”的用户，然后使用 `bitmap_or` 函数计算这两个集合的并集。最后，使用 `bitmap_and_cardinality` 函数计算并集中的元素数量，即喜欢“篮球”和“足球”的用户数量。
-
-#### 注意事项
-* 确保输入参数的数据类型为 bitmap，否则会导致函数执行失败。
-* 当输入的 bitmap 为空时，函数返回 0。

-```
-结果：按 array 形式表示为 `[1]`，具体客户端支持的 bitmap 打印方式可能有所不同。
-
-3. 计算两个较大规模的 bitmap 集合差：
-```sql
-SELECT bitmap_to_array(bitmap_andnot(
-  bitmap_build(array(1, 2, 3, 4, 5, 6, 7, 8, 9)),
-  bitmap_build(array(3, 4, 5, 6, 7, 8, 9, 10))
-));
-```
-结果：按 array 形式表示为 `[1, 2]`
-
-4. 在实际业务场景中，可以利用 BITMAP_ANDNOT 函数对用户兴趣标签进行筛选。例如，从兴趣标签库中排除掉某些特定用户群体不感兴趣的标签：
-```sql
-SELECT user_interests
-FROM users
-WHERE user_id = 1;
-```
-假设上述查询结果为：
-```
-user_id | user_interests
---------+-----------------
-1       | 0000000000001111
-```
-现在我们要排除掉用户不感兴趣的标签 4 和 5：
-```sql
-SELECT bitmap_andnot(user_interests, bitmap_build(array(4, 5)))
-FROM users
-WHERE user_id = 1;
-```
-结果：
-```
-user_id | user_interests
---------+-----------------
-1       | 0000000000000101
-```
-通过 BITMAP_ANDNOT 函数，我们成功地从用户兴趣标签中排除了不感兴趣的标签 4 和 5。

-### BITMAP_ANDNOT_CARDINALITY 函数
-
-
-#### 功能描述
-BITMAP_ANDNOT_CARDINALITY 函数用于计算两个 bitmap 类型参数的集合差（即 ANDNOT 操作），并返回结果 bitmap 中元素的数量。该函数在处理大规模数据集时，能够高效地进行集合操作，尤其适用于需要快速计算集合之间关系的场景。
-
-#### 函数语法
-```
-bitmap_andnot_cardinality(left, right)
-```
-* left: 第一个 bitmap 参数。
-* right: 第二个 bitmap 参数。
-
-#### 返回类型
-返回一个 bigint 类型的值，表示结果 bitmap 中元素的数量。
-
-#### 使用示例
-以下示例展示了如何使用 BITMAP_ANDNOT_CARDINALITY 函数来计算两个 bitmap 的集合差，并获取结果中元素的数量。
-
-**示例 1**：计算两个简单 bitmap 的集合差
-```sql
-SELECT bitmap_andnot_cardinality(
-    bitmap_build(array(1, 2, 3)),

-```
-在这个例子中，第一个 bitmap 包含元素 1、2 和 3，第二个 bitmap 包含元素 2、3 和 4。集合差操作后，结果 bitmap 只包含第一个 bitmap 中存在但第二个 bitmap 中不存在的元素，即只包含元素 1，因此结果为 1。
-
-**示例 2**：在实际数据表中应用 BITMAP_ANDNOT_CARDINALITY 函数
-假设我们有一个名为 `orders` 的数据表，其中包含以下列：`order_id`、`customer_id` 和 `order_date`。我们想要找出在特定日期范围内，某个特定客户没有下过的订单数量。
-
-```sql

-                       array_agg(DISTINCT order_id)
-                   ) FROM orders
-                   WHERE order_date BETWEEN '2022-01-01' AND '2022-01-31'
-               )
-           ),
-           -- 构建特定客户所有订单的 bitmap
-           bitmap_build(
-               array_agg(DISTINCT order_id)
-           ) FROM orders
-           WHERE customer_id = 12345
-       ) AS orders_count
-FROM orders
-WHERE order_date BETWEEN '2022-01-01' AND '2022-01-31'
-GROUP BY customer_id;
-```
-在这个例子中，我们首先使用 `bitmap_union` 函数来构建特定日期范围内所有订单的 bitmap。然后，我们使用 `bitmap_build` 函数来构建特定客户所有订单的 bitmap。最后，我们使用 BITMAP_ANDNOT_CARDINALITY 函数来计算这两个 bitmap 的集合差，并返回结果中元素的数量，即该客户在特定日期范围内没有下过的订单数量。

-   结果将以数组形式展示，但实际上是一个 bitmap 类型：
-   ```
-   [1,2,3]
-   ```
-   
-2. 将上述结果转换回数组形式以验证其内容：
-   ```sql
-   SELECT bitmap_to_array(bitmap_build(array(1, 2, 3)));
-   ```
-   结果将显示为数组形式：
-   ```
-   [1,2,3]
-   ```
-
-3. 构建一个包含多个连续整数的 bitmap 类型：
-   ```sql
-   SELECT bitmap_build(array(1, 2, 3, 4, 5));
-   ```
-   结果将展示为：
-   ```
-   [1,2,3,4,5]
-   ```
-
-4. 从包含负整数和零值的数组构建 bitmap 类型：
-   ```sql
-   SELECT bitmap_build(array(-1, 0, 2, -3));
-   ```
-   结果将展示为：
-   ```
-   [-1, 0, 2, -3]
-   ```
-
-#### 注意事项
-- 客户端不支持直接打印 bitmap 类型的结果，如果直接查看 bitmap 结果会报错，因此在实际使用中如需显示，需要使用 bitmap_to_array 函数将其转化为 array。
-- 当处理大型数据集时，bitmap 类型可以提高查询性能，因为它占用的内存空间相对较小。
-
-通过以上示例和说明，您可以更好地理解如何使用 `bitmap_build` 函数从整数数组构建 bitmap 类型，并在实际应用中发挥其优势。

-   ```sql
-   SELECT bitmap_or(bitmap_build(array(1, 2, 3)), bitmap_build(array(2, 3, 4)));
-   ```
-   预期结果：`[1, 2, 3, 4]` （结果以 array 形式展示，实际客户端可能不支持 bitmap 类型打印）
-
-2. **结合数组函数使用**  
-   使用 bitmap_or 函数处理数组，并转换结果为数组形式：
-   ```sql
-   SELECT bitmap_to_array(bitmap_or(bitmap_build(array(1, 2, 3)), bitmap_build(array(2, 3, 4))));
-   ```
-   预期结果：`[1, 2, 3, 4]`
-
-3. **多集合运算**  
-   对多个 bitmap 进行连续的 OR 运算：
-   ```sql
-   SELECT bitmap_to_array(bitmap_or(bitmap_or(bitmap_build(array(1, 2, 3)), bitmap_build(array(2, 3, 4))), bitmap_build(array(3, 4, 5))));
-   ```
-   预期结果：`[1, 2, 3, 4, 5]`
-
-4. **处理空值**  
-   当输入的 bitmap 之一为空时，结果将反映非空的 bitmap：
-   ```sql
-   SELECT bitmap_to_array(bitmap_or(bitmap_build(array(1, 2, 3)), NULL));
-   ```
-   预期结果：`[1, 2, 3]`
-
-#### 注意事项
-- 客户端不支持直接打印 bitmap 类型的结果，如果直接查看bitmap结果会报错，因此在实际使用中如果要屏显需要使用bitmap_to_array转化成array。
-* BITMAP_OR 函数要求两个输入参数都是 bitmap 类型，否则将返回错误。
-* 当处理大型数据集时，请注意内存使用情况，因为 bitmap 可能会占用较大的内存空间。
-
-
-通过以上示例和说明，您可以更好地理解 BITMAP_OR 函数的用途和使用方法。在实际应用中，BITMAP_OR 函数可以有效地处理和分析 bitmap 类型数据，帮助您完成复杂的数据集合运算任务。

-### BIT_COUNT 函数
-
-#### 概述
-`BIT_COUNT` 函数用于计算给定整数表达式中非零位的数量。该函数对于分析数据的位模式非常有用。
-
-#### 语法
-```
-BIT_COUNT(expr)
-```
-
-#### 参数
-- `expr`: 可以是任何整数类型的表达式，包括 `TINYINT`、`SMALLINT`、`INT` 和 `BIGINT`。
-
-#### 返回结果
-返回一个 `INT` 类型的值，表示输入表达式中非零位的数量。
-
-#### 使用示例
-1. 计算正整数的非零位数量：
-   ```sql
-   SELECT BIT_COUNT(100); -- 返回 3，因为二进制表示为 1100100
-   ```
-
-2. 计算负整数的非零位数量：
-   由于不同系统对负数的表示方式不同（如二进制补码），计算结果可能与预期有所差异。在 LakeHouse 中，可以通过显式转换为特定长度的整数类型来获得一致的结果。
-   ```sql
-   SELECT BIT_COUNT(-100), BIT_COUNT(CAST(-100 AS TINYINT)), BIT_COUNT(CAST(-100 AS SMALLINT)), BIT_COUNT(CAST(-100 AS INT)), BIT_COUNT(CAST(-100 AS BIGINT));
-   -- 返回 28, 4, 12, 28, 60
-   ```
-
-3. 计算不同整数类型的非零位数量：
-   ```sql
-   SELECT BIT_COUNT(CAST(123 AS TINYINT)), BIT_COUNT(CAST(123 AS SMALLINT)), BIT_COUNT(CAST(123 AS INT)), BIT_COUNT(CAST(123 AS BIGINT));
-   -- 返回 4, 4, 4, 4
-   ```
-
-4. 对于包含多个整数的列，可以逐个计算它们的非零位数量：
-   ```sql
-   SELECT BIT_COUNT(col1), BIT_COUNT(col2) FROM table_name;
-   ```
-
-#### 注意事项

-### BITNOT 函数
-
-#### 概述
-BITNOT 函数用于对整数类型的表达式进行按位取反操作。该函数可以处理任何整数类型的输入，并返回与输入类型相同的结果。除了使用 `bitnot()` 函数外，也可以使用 `~` 运算符实现相同的功能。
-
-#### 语法
-```
-BITNOT(expr)
-```
-或
-```
-~expr
-```
-
-#### 参数
-- `expr`：需要进行按位取反操作的整数类型表达式。
-
-#### 返回值
-- 返回与输入参数 `expr` 类型相同的按位取反后的结果。
-
-#### 使用示例
-1. 对单个整数进行按位取反操作：
-   ```sql
-   SELECT BITNOT(100); -- 返回结果: -101
-   SELECT ~100;       -- 返回结果: -101
-   ```
-
-2. 对查询结果中的整数进行按位取反操作：
-   ```sql
-   SELECT BITNOT(column_name) FROM table_name WHERE condition;
-   SELECT ~column_name FROM table_name WHERE condition;
-   ```

-### BETWEEN 操作符
-
-#### 功能描述
-BETWEEN 操作符用于判断某个表达式（expr1）是否处于另外两个表达式（expr2 和 expr3）之间的范围内。如果 expr1 的值在 expr2 和 expr3 之间（包括 expr2 和 expr3），则返回 true，否则返回 false。
-
-#### 语法
-```sql
-expr1 [NOT] BETWEEN expr2 AND expr3
-```
-
-#### 参数说明
-- `expr1`: 需要判断的表达式，可以是小整数（smallint）、 tinyint、整数（int）、大整数（bigint）、浮点数（float）、双精度浮点数（double）、十进制数（decimal）、日期（date）、字符串（string）、字符（char）或可变长字符串（varchar）类型。
-- `expr2`: 范围的起始值，与 expr1 进行比较的表达式。
-- `expr3`: 范围的结束值，与 expr1 进行比较的表达式。
-- `NOT` (可选): 使用 NOT 关键字表示对结果取反，即如果 expr1 不在 expr2 和 expr3 之间，则返回 true。
-
-#### 返回结果
-返回一个布尔值（boolean），表示 expr1 是否在 expr2 和 expr3 之间。
-
-#### 使用示例
-1. 判断数字是否在指定范围内：
-   ```sql
-   > SELECT 5 BETWEEN 3 AND 7;
-   true
-   ```
-   上述示例中，数字 5 在 3 和 7 之间，所以返回 true。
-
-2. 判断字符串是否在指定范围内：
-   ```sql
-   > SELECT 'C' BETWEEN 'A' AND 'E';
-   true
-   ```
-   上述示例中，字符串 'C' 在 'A' 和 'E' 之间，所以返回 true。
-
-3. 判断日期是否在指定范围内：
-   ```sql
-   > SELECT '2021-08-01' BETWEEN '2021-01-01' AND '2021-12-31';
-   true
-   ```
-   上述示例中，日期 '2021-08-01' 在 '2021-01-01' 和 '2021-12-31' 之间，所以返回 true。
-
-4. 使用 NOT 关键字判断 expr1 是否不在 expr2 和 expr3 之间：
-   ```sql
-   > SELECT 0 NOT BETWEEN 1 AND 3;
-   true
-   ```
-   上述示例中，数字 0 不在 1 和 3 之间，使用 NOT 关键字后返回 true。
-
-#### 注意事项
-- 当 expr2 和 expr3 的类型不一致时，系统会尝试进行隐式类型转换，以满足操作符的要求。
-- 对于字符串类型的参数，比较时会按照字典序进行。
-- 对于日期类型的参数，比较时会考虑日期的先后顺序。

-### CASE 表达式
-
-#### 1. 概述
-
-CASE 表达式是 SQL 中的一种条件选择结构，它允许基于一系列条件返回不同的结果。CASE 表达式有两种形式：基于表达式的 CASE 和基于条件的 CASE。它们都可以用于在查询中实现分支逻辑。
-
-#### 2. 基于表达式的 CASE
-
-语法：
-
-```sql
-CASE expr {WHEN opt1 THEN res1} [...] [ELSE def] END
-```
-
-功能：
-
-- 当表达式 `expr` 与某个 `optN` 相等时，返回对应的结果 `resN`。
-- 如果 `expr` 与所有 `optN` 都不相等，则返回默认值 `def`。如果没有指定 `def`，则返回 `null`。
-
-参数：
-
-- `expr`：需要比较的任意类型表达式。
-- `optN`：与 `expr` 类型相同的条件表达式，用于比较。
-- `resN`：当条件匹配时返回的结果表达式。
-- `def`：当没有匹配条件时的默认结果表达式。
-
-示例：
-
-```sql
-SELECT
-  CASE col
-    WHEN 1 THEN 'a'
-    WHEN 2 THEN 'b'
-    ELSE 'c'
-  END AS result
-FROM VALUES(1), (2), (3) AS t(col);
-```
-
-结果：
-
-```
-result
-a
-b
-c
-```
-
-#### 3. 基于条件的 CASE
-
-语法：
-
-```sql
-CASE {WHEN cond1 THEN res1} [...] [ELSE def] END
-```
-
-功能：
-
-- 当条件 `condN` 为 `true` 时，返回对应的结果 `resN`。
-- 如果所有条件都不满足，则返回默认值 `def`。如果没有指定 `def`，则返回 `null`。
-
-参数：
-
-- `condN`：布尔表达式，用于判断分支是否满足条件。
-- `resN`：当条件满足时返回的结果表达式。
-- `def`：当没有满足条件时的默认结果表达式。
-
-示例：
-
-```sql
-SELECT
-  CASE
-    WHEN col = 1 THEN 'a'
-    WHEN col = 2 THEN 'b'
-    ELSE 'c'
-  END AS result
-FROM VALUES(1), (2), (3), (4) AS t(col);
-```
-
-结果：
-
-```
-result
-a
-b
-c
-null
-```
-
-#### 4. 应用场景
-
-- 数据转换：根据不同的条件对数据进行转换或映射。
-- 分组统计：在分组统计时，根据某些条件对数据进行分类。
-- 查询优化：在查询过程中，根据条件过滤或选择需要的数据。
-
-#### 5. 注意事项
-
-- 确保 `resN` 和 `def` 的数据类型一致。
-- 在使用基于条件的 CASE 表达式时，确保所有条件互斥，避免产生歧义。
-- 在实际应用中，根据具体需求选择合适的 CASE 表达式形式。

-### COALESCE 函数
-
-#### 概述
-
-`COALESCE` 函数用于返回其参数列表中第一个非空（non-null）的表达式值。如果所有参数都是空值（null），则返回空值（null）。
-
-#### 语法
-
-```sql
-COALESCE(expr1 [, ...])
-```
-
-#### 参数
-
-* `exprN`: 待验证的表达式，参数数量可变，但至少需要一个。参数类型可以不同，返回值类型与第一个非空参数的类型相同。
-
-#### 返回值
-
-* 返回参数列表中第一个非空的表达式值，如果所有参数均为空值，则返回空值（null）。
-
-#### 使用示例
-
-**示例 1：基本使用**
-
-```sql
- SELECT COALESCE(null, 'A', null, 'B', 'C') as res;
-+-----+
-| res |
-+-----+
-| A   |
-+-----+
-```
-
-在此示例中，`COALESCE` 函数返回第一个非空参数 `'A'`。
-
-**示例 2：处理多个可能为空的字段**
-
-```sql
-SELECT COALESCE(column1, column2, column3) AS non_null_value
-FROM table_name;
-```
-
-假设 `column1`、`column2` 和 `column3` 均有可能包含空值。此查询将返回这三个字段中的第一个非空值。
-
-#### 注意事项
-
-* `COALESCE` 函数在处理参数时，一旦找到第一个非空值，就会停止检查后续参数。
-* 当所有参数均为空值时，`COALESCE` 函数返回空值（null），不会引发错误。
-* 在比较参数值时，`NULL` 被视为等于 `NULL`，但并不被视为任何其他值，包括它自己。这意味着即使有两个 `NULL` 值，`COALESCE` 也不会将它们视为相等。

-### DECODE 函数
-```
-DECODE(expr, search1, result1 [, search2, result2,] ... [, default])
-```
-#### 功能描述
-DECODE 函数是一个条件表达式函数，它根据给定的 expr 表达式与 searchN 条件表达式的匹配结果，返回对应的 resultN 结果表达式。当 expr 与任一 searchN 相等时，返回相应的 resultN。如果 expr 与所有 searchN 都不相等，并且提供了 default 默认结果表达式，则返回 default。如果没有提供 default，则返回 null。
-
-在进行比较时，null 和 null 被认为是相等的。
-
-#### 参数说明
-- expr：任意类型的待匹配表达式。
-- searchN：与 expr 类型相同的判断条件表达式，用于与 expr 进行比较。
-- resultN：结果表达式，其类型需与 searchN 相同。
-- default（可选）：默认结果表达式，当 expr 与所有 searchN 都不相等时返回该值，类型需与 resultN 相同。
-
-#### 使用示例
-1. 基本使用：
-   ```sql
-   SELECT DECODE(3, 6, 'Lakehouse', NULL, 'SQL', 4, 'compiler');
-   -- 结果：'compiler'
-   ```
-   在这个例子中，expr 为 3，与 search1（6）不相等，但与 search2（4）相等，因此返回 result2（'compiler'）。
-
-2. 使用默认值：
-   ```sql
-   SELECT DECODE(5, 6, 'Lakehouse', NULL, 'SQL', 4, 'compiler', 'default');
-   -- 结果：'default'
-   ```
-   当 expr 为 5 时，与所有 searchN 都不相等，因此返回指定的 default 值（'default'）。
-
-3. 处理 null 值：
-   ```sql
-   SELECT DECODE(NULL, NULL, 'Lakehouse', 6, 'SQL', NULL, 'default');
-   -- 结果：'Lakehouse'
-   ```
-   在这个例子中，expr 为 null，与 search1（null）相等，因此返回 result1（'Lakehouse'）。
-
-4. 结合其他函数使用：
-   ```sql
-   SELECT DECODE(SUBSTR('Hello World', 1, 1), 'H', 'Yes', 'W', 'No', 'default');
-   -- 结果：'Yes'
-   ```
-   在这个例子中，我们使用 SUBSTR 函数获取字符串 'Hello World' 的第一个字符 'H'，然后使用 DECODE 函数判断该字符是否为 'H'。因为 expr 与 search1 相等，所以返回 result1（'Yes'）。
-
-通过以上示例，您可以更好地理解 DECODE 函数的用法和功能。请根据您的实际需求调整参数和表达式。

-* `IS_TRUE` 函数识别以下字符串为 `false`：'f', 'false', '0', 'no'。
-* 与直接使用 `expr` 的区别：`is_true(NULL)` 返回 `false`，而 `NULL` 在布尔上下文中会被特殊处理。
-* 字符串匹配不区分大小写。
-
-#### 使用示例
-
-1. 布尔值判断
-
-```sql
-SELECT is_true(true), is_true(false), is_true(NULL);
-+---------------+----------------+----------------+
-| is_true(true) | is_true(false) | is_true(NULL)  |
-+---------------+----------------+----------------+
-| true          | false          | false          |
-+---------------+----------------+----------------+
-```
-
-2. 字符串判断（支持多种格式）
-
-```sql
-SELECT is_true('t'), is_true('f');
-+--------------+--------------+
-| is_true('t') | is_true('f') |
-+--------------+--------------+
-| true         | false        |
-+--------------+--------------+
-```
-
-3. 在 WHERE 子句中使用
-
-```sql
-SELECT * FROM VALUES (true), (false), (NULL) AS t(flag)
-WHERE is_true(flag);
-+------+
-| flag |
-+------+
-| true |
-+------+

-#### 简介
-
-`multiIf` 函数是一种条件逻辑函数，它允许您在查询中更紧凑地编写类似 `CASE` 语句的逻辑。该函数按照指定的顺序评估多个条件，并返回第一个为真的条件对应的值。如果所有条件都不满足，则返回最后一个 `else` 表达式的值。
-
-#### 语法
-
-```Plain
-multiIf(cond_1, then_1, cond_2, then_2, ..., else)
-```
-
-#### 参数
-
-* `cond_N`：要评估的第 N 个条件。
-* `then_N`：当第 N 个条件为真时返回的值。
-* `else`：如果所有条件都不满足时返回的值。
-
-#### 返回结果
-
-* 返回任何一个 `then_N` 表达式的值，如果所有条件都不满足，则返回 `else` 表达式的值。
-
-#### 使用示例
-
-```SQL
-
-SELECT    name,
-          score,
-          multiIf (
-          score >= 90,
-          'A',
-          score >= 80,
-          'B',
-          score >= 70,
-          'C',
-          score >= 60,
-          'D'        
-          ) AS grade
-FROM     
-VALUES    ('Alice', 92),('Bob', 85),('Charlie', 77),('David', 63),('Eve', 58) students (name, score);
-+---------+-------+-------+
-|  name   | score | grade |
-+---------+-------+-------+
-| Alice   | 92    | A     |
-| Bob     | 85    | B     |
-| Charlie | 77    | C     |
-| David   | 63    | D     |
-| Eve     | 58    |       |
-+---------+-------+-------+
-```
-
-#### 注意事项
-
-* 如果 `multiIf` 函数中不包含 `else` 部分，当所有条件都不满足时，函数将返回 `NULL`。

-### NVL 函数
-
-```
-nvl(expr1, expr2)
-```
-
-#### 功能描述
-NVL 函数用于处理 SQL 查询中的 NULL 值。当 expr1 的值为 NULL 时，NVL 函数返回 expr2 的值，否则返回 expr1 的值。这个函数可以确保返回的结果不包含 NULL 值，便于后续的数据处理和分析。
-
-#### 参数说明
-- expr1：任意类型的表达式，当其值为 NULL 时，将使用 expr2 的值作为替代。
-- expr2：与 expr1 类型相同的表达式，当 expr1 为 NULL 时，作为替代值返回。
-
-#### 返回结果
-返回结果的类型与 expr1 和 expr2 的类型相同。
-
-#### 使用示例
-
-1. 查询员工工资，如果某员工工资为 NULL，则显示为 "未知"：
-```sql
-SELECT name, nvl(salary, '未知') AS salary FROM employees;
-```
-
-2. 计算订单总金额，如果某个订单的金额为 NULL，则将其金额视为 0：
-```sql
-SELECT order_id, nvl(amount, 0) AS total_amount FROM orders;
-```
-
-3. 比较两个数值型字段，如果其中一个字段为 NULL，则返回另一个字段的值：
-```sql
-SELECT product_id, nvl(column1, column2) AS result FROM products;
-```
-
-4. 根据学生考试成绩判断是否及格，如果成绩为 NULL，则将其视为及格：
-```sql
-SELECT student_id, nvl(score, 60) AS adjusted_score FROM student_scores;
-```
-
-通过以上示例，您可以看到 NVL 函数在处理 SQL 查询中的 NULL 值时非常有用。它可以帮助您在数据分析和报表生成中避免因 NULL 值而产生的问题。

-### DATE 函数
-
-#### 功能描述
-
-DATE 函数用于将不同类型的日期表达式转换为日期类型，即 `DATE` 类型。它可以处理多种输入格式，包括字符串、时间、时间戳等。DATE 函数与 `CAST(expr AS DATE)` 的功能相同。
-
-#### 支持的参数
-
-* `expr`：可以是字符串、时间、时间戳等能够被转换成日期类型的表达式。
-
-#### 返回结果
-
-* 返回一个日期类型的结果，格式为 `YYYY-MM-DD`。
-
-#### 使用示例
-
-1.  字符串转日期：
-    ```sql
-   SELECT DATE('2022-01-01');
-   -- 结果：2022-01-01
-   ```
-    ```sql
-   SELECT DATE('2022/01/01');要求格式必须是YYYY-MM-DD格式
-   -- 结果：null
-   ```
-2.  时间转日期：
-    ```sql
-   SELECT DATE('22:12:30');要求格式必须是YYYY-MM-DD格式
-   -- 结果：null
-   ```
-    ```sql
-   SELECT DATE(TIMESTAMP "2022-01-01 22:12:30");
-   -- 结果：2022-01-01
-   ```
-
-#### 注意事项
-
-* 当输入的字符串无法识别为有效的日期时，DATE 函数将返回 `NULL`。
-* 在转换过程中，DATE 函数会自动忽略输入表达式中的时区信息，只保留日期部分。
-* 如果输入的时间超出了数据库支持的时间范围，可能会导致转换失败或返回意外的结果。

-```
-#### 功能描述
-该函数用于计算并返回在给定的日期 `startDate` 基础上增加 `numDays` 天后的日期。如果计算结果超出了系统所支持的日期范围，则会返回 `null`。
-
-#### 参数说明
-- `startDate` (date): 起始日期，需要符合日期格式。
-- `numDays` (int): 需要增加的天数，可以为正整数（增加天数）或负整数（减少天数）。
-
-#### 返回结果
-返回一个新的日期，该日期是 `startDate` 加上 `numDays` 天之后的结果，如果结果超出日期范围，则返回 `null`。
-
-#### 使用示例
-1. 增加天数：
-```sql
-SELECT date_add('2020-05-31', 10); -- 返回 2020-06-10
-```
-2. 减少天数：
-```sql
-SELECT date_add('2020-06-10', -3); -- 返回 2020-06-07
-```
-3. 跨年计算：
-```sql
-SELECT date_add('2020-12-31', 1); -- 返回 2021-01-01
-```
-4. 超出日期范围：
-```sql
-SELECT date_add('9999-12-31', 1); -- 返回 null
-```
-#### 注意事项
-- 确保 `startDate` 参数为有效的日期格式，否则可能导致函数返回 `null`。
-- 当 `numDays` 为负数时，表示从 `startDate` 往回推 `numDays` 天。
-- 请留意系统所支持的日期范围，超出范围的计算结果将返回 `null`。

-### LAST_DAY 函数
-#### 功能描述
-`LAST_DAY` 函数用于获取给定日期（`date` 类型）或时间戳（`timestamp_ltz` 类型）参数所在月份的最后一天。这个函数通常用于日期计算和报告生成，帮助用户快速确定某个日期所在的月份的结束日期。
-
-#### 参数说明
-- `expr`: 输入的日期或时间戳参数，类型为 `date` 或 `timestamp_ltz`。
-
-#### 返回结果
-返回一个 `date` 类型的结果，表示输入参数在当月的最后一天。
-
-#### 使用示例
-1. 确定普通日期的月末最后一天：
-   ```sql
-   SELECT LAST_DAY('2020-02-05'); -- 结果为 2020-02-29
-   ```
-2. 确定时间戳的月末最后一天：
-   ```sql
-   SELECT LAST_DAY(TIMESTAMP_LTZ "2020-02-05 12:00:00"); -- 结果为 2020-02-29
-   ```
-3. 计算闰年二月的最后一天：
-   ```sql
-   SELECT LAST_DAY('2020-02-05'); -- 结果为 2020-02-29
-   ```
-   在这个例子中，由于 2020 年是闰年，二月有 29 天，所以返回的是 2020-02-29。
-4. 对于非闰年的二月：
-   ```sql
-   SELECT LAST_DAY('2021-02-05'); -- 结果为 2021-02-28
-   ```
-   在这个例子中，2021 年不是闰年，所以二月的最后一天是 2021-02-28。
-
-#### 注意事项
-- 当输入的日期或时间戳参数为所在月份的最后一天时，`LAST_DAY` 函数将返回该日期或时间戳本身。
-- 在处理时间戳参数时，请注意时区的影响。`timestamp_ltz` 类型的时间戳不包含时区信息，因此在计算时可能会依赖系统或会话的当前时区设置。
-
-通过以上示例和说明，您可以更好地理解 `LAST_DAY` 函数的用途和用法，从而在实际工作中更有效地进行日期处理。

-
-#### 语法
-```
-now()
-```
-#### 参数
-无
-
-#### 返回结果类型
-`timestamp_ltz`
-
-#### 使用示例
-以下是一个简单的使用 `now` 函数的例子：
-
-```sql
-SELECT now();
-```
-
-执行上述 SQL 语句后，将返回类似于以下的结果，具体时间会根据查询执行时的实际时间而变化：
-
-```
-2022-01-01 15:17:22.098368
-```
-
-#### 更多例子
-1. 插入数据时使用当前时间戳作为记录创建时间：
-
-```sql
-INSERT INTO my_table (id, name, created_at) VALUES (1, 'John Doe', now());
-```
-
-2. 在更新数据时，使用当前时间戳作为记录最后更新时间：
-
-```sql
-UPDATE my_table SET name = 'Jane Doe', updated_at = now() WHERE id = 1;
-```
-
-3. 选择数据时，过滤出在过去 24 小时内创建的记录：
-
-```sql
-SELECT * FROM my_table WHERE created_at > now() - INTERVAL '1 day';
-```
-
-4. 比较当前时间与记录的最后更新时间，判断记录是否在最近一小时内有变动：
-
-```sql
-SELECT * FROM my_table WHERE updated_at > now() - INTERVAL '1 hour';
-```
-
-通过以上示例，您可以更好地理解 `CURRENT_TIMESTAMP` 函数在实际应用中的使用场景。

-### HASH_COMBINE 和 HASH_COMBINE_COMMUTATIVE 函数
-
-#### 功能描述
-`hash_combine` 函数用于将多个哈希值 h1, h2, ..., hN 组合成一个新的哈希值。该函数的特点是组合值的顺序会影响最终的哈希值。
-
-`hash_combine_commutative` 函数与 `hash_combine` 类似，也用于将多个哈希值 h1, h2, ..., hN 组合成一个新的哈希值。不同之处在于，该函数的特点是组合值的顺序不会影响最终的哈希值，即满足交换律。
-
-#### 参数说明
-* `h1`, `h2`, ..., `hN`: bigint 类型，表示要组合的哈希值。
-
-#### 返回结果
-返回一个 `bigint` 类型的值，表示组合后的哈希值。
-
-#### 使用示例
-以下示例展示了如何使用 `hash_combine` 和 `hash_combine_commutative` 函数：
-
-```sql
--- 使用 hash_combine 函数
-SELECT hash_combine(1, 2, 3) AS hash_combine_result1;
--- 结果：175247765312
-
-SELECT hash_combine(3, 2, 1) AS hash_combine_result2;
--- 结果：175247756320
-
--- 使用 hash_combine_commutative 函数
-SELECT hash_combine_commutative(1, 2, 3) AS hash_commutative_result1;
--- 结果：10777284388
-
-SELECT hash_combine_commutative(3, 2, 1) AS hash_commutative_result2;
--- 结果：10777284388
-```
-
-从上述示例中可以看出，`hash_combine` 函数在组合值的顺序改变时，结果也会发生变化；而 `hash_combine_commutative` 函数在组合值的顺序改变时，结果保持不变。
-
-#### 注意事项
-* 当需要组合的哈希值数量较少时，可以使用这两个函数。但如果需要合并大量的哈希值，建议使用其他方法，以避免性能问题。
-* 在实际应用中，可以根据具体需求选择合适的函数。如果对组合值的顺序有要求，可以使用 `hash_combine` 函数；如果对顺序无要求，可以使用 `hash_combine_commutative` 函数。

-### 高阶函数
-高阶函数是那些接受一个或多个 lambda 函数作为参数的函数。在 SQL 语言中，lambda 函数通常用于处理数组、映射等复杂数据类型，以及在子查询中进行计算。
-
-#### Lambda 函数语法
-Lambda 函数的语法格式为 `arg -> expr` 或者 `(arg1, arg2) -> expr`：
-1. `->` 左侧为参数列表，可以表示数组中的元素，也可以表示映射中的键值对。参数绑定的具体含义取决于高阶函数的语义。
-2. `->` 右侧为 lambda 函数的计算体，即对形参的计算。在表达式 `expr` 中，可以引用外部查询或子查询中的列名。
-
-#### 使用示例
-1. 数组元素处理：
-``` sql
-SELECT transform(array(1, 2, 3), x -> x + 1);
--- 结果：[2, 3, 4]
-```
-上述示例中，我们对数组 `[1, 2, 3]` 中的每个元素 `x` 应用 lambda 函数 `x -> x + 1`，得到新数组 `[2, 3, 4]`。
-
-2. 映射元素处理：
-``` sql
-SELECT transform(map('a', 1, 'b', 2), (k, v) -> k || ' : ' || v);
--- 结果：{'a' : 'a : 1', 'b' : 'b : 2'}
-```
-在这个例子中，我们对映射 `{'a' : 1, 'b' : 2}` 中的每个键值对 `(k, v)` 应用 lambda 函数 `(k, v) -> k || ' : ' || v`，得到新的映射 `{'a' : 'a : 1', 'b' : 'b : 2'}`。
-
-3. 捕获外部列：
-``` sql
-SELECT transform(array(1, 2, 3), x -> x + a) FROM (SELECT 100 AS a) AS sub;
--- 结果：[101, 102, 103]
-```
-在这个例子中，我们从子查询中捕获列 `a` 的值，并将其与数组 `[1, 2, 3]` 中的元素 `x` 相加，得到新数组 `[101, 102, 103]`。
-
-#### 注意事项
-1. Lambda 函数的参数列表应与高阶函数期望的参数类型和数量相匹配。
-2. 在 lambda 函数中，可以引用外部查询或子查询中的列名，但需确保其可读性和正确性。
-3. 高阶函数的具体用法和语义因函数而异，使用前请仔细阅读相关文档。

-### MAP_FILTER 函数
-
-#### 功能描述
-MAP_FILTER 函数用于根据给定的 lambda 表达式筛选 map 类型的元素。该函数接收两个参数：第一个参数为 map 类型的数据，第二个参数为一个二参形式的 lambda 表达式，分别对应 map 中的键（k）和值（v）。lambda 表达式需要返回一个布尔值，用于判断当前键值对是否应该保留在结果中。
-
-#### 参数说明
-- map: 输入的 map<K, V> 类型数据。
-- (k, v) -> expr: 一个二参形式的 lambda 表达式，k 和 v 分别代表 map 中的键和值。expr 需要返回一个布尔值，表示当前键值对是否应该被保留。
-
-#### 返回值
-返回一个新的 map<K, V> 类型数据，其中仅包含满足 lambda 表达式条件的键值对。
-
-#### 使用示例
-1. 筛选 map 中值小于等于 2 的元素：
-   <= 2);
-   // 结果：{2: "a", 1: "b"}
-   ```
-2. 筛选 map 中值小于等于 'b' 的元素：
-   ```sql
-   SELECT `map_filter`(map(2, 'a', 1, 'b', 3, 'c'), (k, v) ->
-2. 筛选 map 中值长度大于 1 的元素：
-   ```sql
-   SELECT `map_filter`(map(2, 'a', 1, 'bb', 3, 'c'), (k, v) -> LENGTH(v) > 1);

-### MAP_ZIP_WITH 函数
-
-#### 功能描述
-MAP_ZIP_WITH 函数能够根据给定的 lambda 表达式，将两个 map 类型数据中 key 值相同的元素进行配对计算。计算过程中，若某个 key 在其中一个 map 中不存在对应值，则会补入 NULL 值。最终，该函数会返回一个新的 map，其中包含原始 key 值以及根据 lambda 表达式计算得到的新值。
-
-#### 参数说明
-- map1, map2: 输入的两个 map 类型数据，类型为 `map<K, V>`。
-- `(k, v1, v2) -> expr`: 一个三参数形式的 lambda 表达式，其中 `k` 为匹配的 key 值，`v1` 为 `map1` 中对应的 value，`v2` 为 `map2` 中对应的 value。lambda 表达式的返回值类型不限，但所有返回值必须为同一类型。
-
-#### 返回类型
-返回一个新的 map 类型数据，类型为 `map<K, R>`，其中 `R` 为 lambda 表达式计算得到的值类型。
-
-#### 使用示例
-1. 计算两个 map 中相同 key 对应 value 的和，并返回新的 map：
-```sql
-SELECT map_zip_with(map(1, 2, 3, 4), map(2, 3, 4, 5), (k, x, y) -> x + y);
-```
-结果：
-```
-{1:null,3:null,2:null,4:null} 
-```
-
-2. 将两个 map 中相同 key 对应的 value 转换为字符串并拼接，返回新的 map：
-```sql
-SELECT map_zip_with(map(1, "a", 2, "b"), map(1, "A", 2, "B"), (k, x, y) -> CONCAT(x, y));
-```
-结果：
-```
-{1:"aA", 2:"bB"}
-```
-
-3. 对两个 map 中相同 key 对应的 value 进行类型转换并相加，返回新的 map：
-```sql
-SELECT map_zip_with(map(1, 2), map(1, 100, 3, 300), (k, x, y) -> CAST((x + y) AS string));
-```
-结果：
-```
-{1:"102", 3:null}
-```
-
-#### 注意事项
-- 当 key 在一个 map 中不存在对应值时，会补入 NULL 值参与计算。
-- 请确保 lambda 表达式中的参数顺序与实际传入的参数顺序相符。
-- 返回的新 map 中，key 值的顺序可能与原始 map 中的顺序不同。
-
-通过以上描述和示例，您可以更好地理解和使用 MAP_ZIP_WITH 函数。在实际应用中，该函数能够帮助您灵活地对两个 map 类型数据进行操作和计算。

-2. `(k, v) -> expr`: 一个双参数的 lambda 表达式，用于定义值转换的逻辑。`k` 对应 map 中的键，`v` 对应 map 中的值。`expr` 为 lambda 表达式，其返回值类型将作为新 map 中值的类型。
-
-#### 返回类型
-返回一个新的 map 类型数据，格式为 `map<R, V>`，其中 R 为 lambda 表达式的返回值类型。
-
-#### 使用示例
-1. 示例 1：计算字符串长度
-```sql
-SELECT transform_values(map(1, 'hello', 2, NULL, 3, 'world'), (k, v) -> LENGTH(v));
-```
-返回结果：`{1:5, 2:null, 3:5}`
-
-2. 示例 2：将字符串转换为大写
-```sql
-SELECT transform_values(map(1, 'hello', 2, 'sql', 3, 'world'), (k, v) -> UPPER(v));
-```
-返回结果：`{1:'HELLO', 2:'SQL', 3:'WORLD'}`
-
-3. 示例 3：为每个键值对添加后缀
-```sql
-SELECT transform_values(map(1, 'hello', 2, 'world'), (k, v) -> CONCAT(v, '_suffix'));
-```
-返回结果：`{1:'hello_suffix', 2:'world_suffix'}`
-
-#### 注意事项
-1. 当输入的 map 数据中的值为 NULL 时，lambda 表达式需要能够处理 NULL 值，否则可能会导致函数执行失败。
-2. 请确保 lambda 表达式返回值的类型与预期的新 map 中值的类型一致。
-
-通过使用 `transform_values` 函数，您可以灵活地对 map 类型数据进行各种转换操作，从而满足不同的业务需求。

-### ZIP_WITH 函数
-
-#### 功能描述
-ZIP_WITH 函数能够根据提供的 lambda 表达式，对两个数组（array1 和 array2）的对应位置元素进行计算，并生成一个新的数组。当两个输入数组长度不一致时，较短数组的缺失元素位置将补入 NULL 值，然后继续进行计算。
-
-#### 参数说明
-- array1, array2: `array<T>` 类型，需要进行操作的两个数组。
-- `(x1, x2) -> expr`: 二参形式的 lambda 表达式，其中 `x1` 对应 `array1` 的元素，`x2` 对应 `array2` 的元素。`expr` 为表达式内容，其返回值的类型没有限制。
-
-#### 返回类型
-返回一个新的数组，其元素类型与 lambda 表达式返回值的类型一致。
-
-#### 使用示例
-1. 两个数组对应元素相加，并转换为字符串类型：
-```sql
-SELECT zip_with(array(1, 2), array(2, 3), (x, y) -> CAST((x + y) AS string));
--- 返回结果：["3", "5"]
-```
-2. 计算两个数组对应元素的差值：
-```sql
-SELECT zip_with(array(5, 3, 1), array(2, 4, 6), (x, y) -> x - y);
--- 返回结果：[3, -1, -5]
-```
-3. 将两个数组对应元素拼接成新的字符串：
-```sql
-SELECT zip_with(array('a', 'b'), array('x', 'y'), (x, y) -> CONCAT(x, y));
--- 返回结果：['ax', 'by']
-```
-4. 当数组长度不一致时，较短数组的缺失元素位置将补入 NULL 值：
-```sql
-SELECT zip_with(array(1, 2), array(2, 3, 4), (x, y) -> x * y);
--- 返回结果：[2, 6, null]
-```
-#### 注意事项
-- 当输入的数组为空时，ZIP_WITH 函数将返回一个空数组。
-- 当 lambda 表达式中使用到 NULL 值时，其行为应符合 SQL 中对 NULL 的处理规则。
-

-
--- 解析 JSON 数组为整数数组
-SELECT from_json('[1, 2, 3]', 'array<int>');
--- 返回结果：[1,2,3]
-
--- 解析 JSON 对象为映射
-SELECT from_json('{"name": "Alice", "age": 25}', 'map<string, string>');
--- 返回结果：{"name":"Alice","age":"25"}
-
--- 解析 JSON 字符串，其中包含嵌套结构体
-SELECT from_json('{"user": {"name": "Bob", "age": 30}, "active": true}', 'struct<`user`:map<string, string>, active:boolean>');
--- 返回结果：{"user":{"name":"Bob","age":"30"},"active":true}
-
--- 解析 JSON 数组，其中包含嵌套数组
-SELECT from_json('[{"id": 1, "name": "Product A"}, {"id": 2, "name": "Product B"}]', 'array<struct<id:int, name:string>>');
--- 返回结果：[{"id":1,"name":"Product A"},{"id":2,"name":"Product B"}]
-```
-
-#### 注意事项
-
-* 确保提供的 JSON 字符串是合法的，否则函数将返回 `NULL`。
-* 模式定义应与 JSON 字符串中的数据结构相匹配，否则可能导致某些字段无法正确解析。
-* 在处理浮点数和十进制数时，应注意精度可能会受到影响。
-*   在使用 `from_json` 函数从 JSON 字符串中提取指定 schema 的数据时，如果 JSON 字符串中存在大小写敏感的键，可能会导致解析错误或结果不符合预期。例如：
-    ```SQL
-     select from_json('{"A":1,"a":2}','struct<A:bigint,a:bigint>');
-    java.lang.IllegalArgumentException: not all nodes and buffers were consumed. nodes: 
-    ```
-    为了避免这种错误，推荐使用 `parse_json` 函数。`parse_json` 函数能够正确处理大小写敏感的 JSON 键，并且提供了更灵活的数据访问方式。
-    ```SQL
-    select parse_json('{"A":1,"a":2}')['A'] as res;
-    +-----+
-    | res |
-    +-----+
-    | 1   |
-    +-----+
-    select parse_json('{"A":1,"a":2}')['a'] as res;
-    +-----+
-    | res |
-    +-----+
-    | 2   |
-    +-----+
-    
-    ```

-### GET\_JSON\_OBJECT 函数
-
-#### 功能描述
-
-GET\_JSON\_OBJECT 函数用于从 JSON 格式的字符串（str）中提取特定字段的值。它接受两个参数：第一个参数是一个 JSON 格式的字符串，第二个参数是一个字符串，用于指定 JSON 对象中所需提取字段的路径。
-
-#### 语法格式
-
-```
-get_json_object(string <str>, string <path>)
-```
-
-#### 参数说明
-
-* str (string): 一个包含 JSON 格式数据的字符串。
-* path (string): 一个描述所需提取字段位置的字符串路径。可以参考[json path规范](<https://goessner.net/articles/JsonPath/>)
-    * "$" 表示根元素。
-    * ".key" 或者 "\['key']" 用来查找 JSON object 中的 key。特殊的，"\[\*]" 表示获取所有的 value，要求 key 必须用单引号。
-    * "\[index]" 用来根据 index 访问 JSON array 的元素，起始值为 0。特殊的，"\[\*]" 表示所有的元素。
-
-#### 返回值
-
-* 返回指定字段的值，类型为字符串。
-
-#### 使用示例
-
-1. 假设我们有一个 JSON 对象如下所示：
-   ```json
-   {
-     "name": "张三",
-     "age": 30,
-     "address": {
-       "city": "北京",
-       "zipcode": "100000"
-     },
-     "hobbies": ["篮球", "旅游", "阅读"]
-   }
-   ```
-   我们可以使用 GET\_JSON\_OBJECT 函数来提取 JSON 对象中的不同字段，例如：
-   * 提取名字：
-     ```sql
-     SELECT get_json_object('{"name": "张三", "age": 30, "address": {"city": "北京", "zipcode": "100000"}, "hobbies": ["篮球", "旅游", "阅读"]}', '$.name');
-     ```
-     结果：张三
-   * 提取城市：
-     ```sql
-     SELECT get_json_object('{"name": "张三", "age": 30, "address": {"city": "北京", "zipcode": "100000"}, "hobbies": ["篮球", "旅游", "阅读"]}', '$.address.city');
-     ```
-     结果：北京
-   * 提取所有爱好：
-     ```sql
-     SELECT get_json_object('{"name": "张三", "age": 30, "address": {"city": "北京", "zipcode": "100000"}, "hobbies": ["篮球", "旅游", "阅读"]}', '$.hobbies');
-     ```
-     结果：\["篮球", "旅游", "阅读"]
-
-2. 另一个例子，我们有一个 JSON 数组如下所示：
-   ```json
-   [
-     {
-       "id": 1,
-       "name": "产品A",
-       "price": 100
-     },
-     {
-       "id": 2,
-       "name": "产品B",
-       "price": 200
-     }
-   ]
-   ```
-   我们可以使用 GET\_JSON\_OBJECT 函数来提取数组中特定元素的字段，例如：
-   * 提取第一个产品的价格：
-     ```sql
-     SELECT get_json_object('[{"id": 1, "name": "产品A", "price": 100}, {"id": 2, "name": "产品B", "price": 200}]', '$[0].price');
-     ```
-     结果：100
-   * 提取所有产品的名称：
-     ```sql
-     SELECT get_json_object('[{"id": 1, "name": "产品A", "price": 100}, {"id": 2, "name": "产品B", "price": 200}]', '$[*].name');
-     ```
-     结果：\["产品A", "产品B"]
-
-通过以上示例，您可以看到 GET\_JSON\_OBJECT 函数在处理 JSON 数据时的灵活性和实用性。在实际应用中，您可以根据需要自由组合路径字符串，以提取 JSON 数据中的任意字段。

-### JSON_EXTRACT 函数系列
-
-#### 简介
-JSON_EXTRACT 函数系列旨在从 JSON 格式的数据中提取特定元素。这些函数根据提供的 JSON 路径（json_path）从 JSON 对象或数组中提取信息，并将结果返回为相应的数据类型。当指定的元素不存在时，函数返回 NULL。
-
-#### JSON 路径规范
-JSON 路径是一种简洁的查询语法，用于访问 JSON 数据结构中的元素。以下是一些常用的 JSON 路径符号：
-
-- `$`：表示根元素。
-- `.key` 或 `[key]`：用于查找 JSON 对象中的键（key）。特别地，`[*]` 表示获取所有键对应的值。
-- `[index]`：用于根据索引（index）访问 JSON 数组的元素，索引从 0 开始。特别地，`[*]` 表示获取数组中的所有元素。
-
-#### 函数列表
-- `json_extract(json, json_path)`：从 JSON 数据中提取指定的元素，并返回 JSON 格式的结果。
-- `json_extract_boolean(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为布尔值（BOOLEAN）。
-- `json_extract_int(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为整数（INT）。
-- `json_extract_bigint(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为大整数（BIGINT）。
-- `json_extract_float(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为浮点数（FLOAT）。
-- `json_extract_double(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为双精度浮点数（DOUBLE）。
-- `json_extract_string(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为字符串（STRING）。
-- `json_extract_date(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为日期（DATE）。
-- `json_extract_timestamp(json, json_path)`：从 JSON 数据中提取指定的元素，并将其转换为时间戳（TIMESTAMP）。
-
-#### 参数说明
-- `json`：要处理的 JSON 类型数据。
-- `json_path`：用于指定要提取元素的 JSON 路径的字符串。
-
-#### 返回结果
-- 对于 `json_extract_json` 函数，返回提取到的 JSON 格式数据。
-- 对于其他函数（如 `json_extract_boolean` 等），返回提取到的数据转换为指定数据类型的值。
-
-#### 使用示例
-1. 提取 JSON 对象中的嵌套元素：
-   ```sql
-   SELECT json_extract(json'{"a": {"b": 1}}', '$.a');
-   -- 输出：{"b":1}
-   ```
-
-2. 提取 JSON 对象中带有点的键：
-   ```sql
-   SELECT json_extract(json'{"key": 1, "key.with.dot": 2}', '$.key'),
-         json_extract(json'{"key": 1, "key.with.dot": 2}', "$['key.with.dot']");
-   -- 输出：1       2
-   ```
-
-3. 提取 JSON 数组中的所有元素：
-   ```sql
-   SELECT json_extract(json'[1, 2, 3]', '$[*]');
-   -- 输出：[1,2,3]
-   ```
-
-4. 将提取到的 JSON 元素转换为整数：
-   ```sql
-   SELECT json_extract_int(json'{"a": {"b": 1}}', '$.a.b');
-   -- 输出：1
-   ```
-
-5. 将提取到的 JSON 元素转换为布尔值：
-   ```sql
-   SELECT json_extract_boolean(json'{"a": {"b": 1}}', '$.a.b');
-   -- 输出：true
-   ```
-
-通过以上示例，您可以更深入地了解 JSON_EXTRACT 函数系列的使用方法和功能。这些函数为您提供了灵活且高效的方式来处理和分析 JSON 数据。

-### JSON_PARSE 函数
-
-#### 简介
-`JSON_PARSE` 函数用于将 JSON 格式的字符串解析为 JSON 类型。解析后的 JSON 类型在输出时会自动去除多余的空格，且不保证字段（field）的顺序与原始 JSON 字符串完全一致。`PARSE_JSON` 是 `JSON_PARSE` 函数的别名，两者功能相同。
-
-#### 语法
-```
-json_parse(str)
-parse_json(str)
-```
-
-#### 参数
-- `str`: 需要解析的 JSON 格式字符串。
-
-#### 返回结果
-- 返回解析后的 JSON 类型。
-
-#### 使用示例
-
-**示例 1**：解析简单的 JSON 字符串
-```sql
-SELECT json_parse('{"name": "张三", "age": 25}');
-```
-返回结果：
-```json
-{"name":"张三","age":25}
-```
-
-**示例 2**：解析嵌套的 JSON 字符串
-```sql
-SELECT json_parse('{"user":{"name":"李四","age":30},"info":{"city":"北京","country":"中国"}}');
-```
-返回结果：
-```json
-{"user":{"name":"李四","age":30},"info":{"city":"北京","country":"中国"}}
-```
-
-**示例 3**：解析包含数组的 JSON 字符串
-```sql
-select parse_json('{"fruits":["苹果","香蕉","橙子"],"vegetables":["白菜","萝卜"]}') as res;
-```
-返回结果：
-```json
-{"fruits":["苹果","香蕉","橙子"],"vegetables":["白菜","胡萝卜"]}
-```
-
-**示例 4**：解析含有数字和布尔值的 JSON 字符串
-```sql
-SELECT json_parse('{"score":85.5,true_false:true,"count":-100}');
-```
-返回结果：
-```json
-{"score":85.5,"true_false":true,"count":-100}
-```
-
-#### 注意事项
-- 确保输入的字符串为有效的 JSON 格式，否则可能导致解析失败。
-- 在处理复杂的 JSON 字符串时，请注意字符串的缩进和引号使用，以确保正确解析。
-- 由于 JSON 类型在输出时会自动去除多余空格，因此输出结果中的字段顺序可能与原始输入有所不同。

-### TO\_JSON 函数
-
-#### 概述
-
-`TO_JSON` 函数用于将指定的表达式（expr）转换为 JSON 格式的文本。该函数能够处理各种数据类型，并将它们映射到相应的 JSON 类型。这对于在 SQL 查询中处理和输出 JSON 数据非常有用。
-
-#### 类型映射关系
-
-以下是 LakeHouse 数据类型与 JSON 类型之间的对应关系：
-
-* `struct` 和 `map`：转换为 JSON 对象（object）
-* `array`：转换为 JSON 数组（array）
-* `tinyint`、`smallint`、`int`、`bigint`、`float`、`double`：转换为 JSON 数值（numeric）
-* `boolean`：转换为 JSON 布尔值（boolean）
-* `string`：转换为 JSON 字符串（string）
-* `date`、`datetime`：转换为 JSON 字符串，格式为日期或日期时间
-* `null`：转换为 JSON  null 值
-
-需要注意的是，对于 `decimal` 类型，在转换为 JSON 时会以 `double` 类型输出，可能会丢失精度。此外，对于 `map<K, V>` 类型，如果 K 不是 `string`、`char` 或 `varchar` 类型，系统会先将其转换为字符串形式，再进行输出。这是因为 JSON 对象的键（key）必须为字符串类型。
-
-#### 函数语法
-
-```
-TO_JSON(expr)
-```
-
-#### 参数说明
-
-* `expr`：任意类型的表达式。
-
-#### 返回结果
-
-* 返回类型：字符串（string）
-
-#### 使用示例
-
-以下示例展示了如何使用 `TO_JSON` 函数处理不同类型的数据：
-
-1. 将数组映射为 JSON 对象：
-   ```sql
-   SELECT TO_JSON(MAP(ARRAY(1, 2), 2));
-   -- 输出：{"[1,2]":2}
-   ```
-
-2. 将 JSON 字符串直接输出：
-   ```sql
-   SELECT TO_JSON(JSON '{"a": 1}');
-   -- 输出：{"a": 1}
-   ```
-
-3. 将结构体转换为 JSON 对象：
-   ```sql
-   SELECT TO_JSON(NAMED_STRUCT( 'id',1, 'name','John Doe' ));
-   -- 输出：{"id":1,"name":"John Doe"}
-   ```
-
-4. 将 `null` 值转换为 JSON  null：
-   ```sql
-   SELECT TO_JSON(NULL);
-   --输出空字符串
-   +---------------+
-   | TO_JSON(NULL) |
-   +---------------+
-   |               |
-   +---------------+
-   ```
-
-通过以上示例，您可以看到 `TO_JSON` 函数在处理不同类型的数据时的灵活性和实用性。这使得在 SQL 查询中处理 JSON 数据变得更加简单和高效。

-SELECT ACOSH(1); -- 结果为 0.0
-```
-3. 计算接近于 `0` 的小数值的反双曲余弦值：
-```
-SELECT ACOSH(0.0001); -- 结果约为 NaN
-```
-4. 计算负数的反双曲余弦值（结果为 `NaN`，因为 `ACOSH` 函数只接受正数参数）：
-```
-SELECT ACOSH(-1); -- 结果为 NaN
-```
-5. 在一个查询中对多个数值计算反双曲余弦值：

-### MONOTONICALLY_INCREASING_ID
-```sql
-monotonically_increasing_id()
-```
-#### 功能
-生成单调递增的 ID。该函数为每一行生成一个唯一的、单调递增的 64 位整数 ID。在分布式环境中，每个分区生成的 ID 范围不重叠，确保全局唯一性。
-
-#### 参数
-* 无参数
-
-#### 返回结果
-* bigint 类型
-* 返回单调递增的唯一 ID
-* ID 从 0 开始递增
-* 在分布式环境中，不同分区的 ID 不重叠
-
-#### 举例
-```sql
--- 基本用法
-> SELECT a, monotonically_increasing_id() as id
-  FROM VALUES (1), (2), (3), (4), (5) AS t(a);
-1	0
-2	1
-3	2
-4	3
-5	4
-
--- 在分布式环境中使用
-> SELECT a, monotonically_increasing_id() as id
-  FROM VALUES (1), (2), (3), (4), (5), (6), (7), (8), (9), (10) AS t(a)
-  DISTRIBUTE BY a;
-1	8589934592
-2	17179869184
-3	0
-4	8589934593
-5	17179869185
-6	8589934594
-7	0
-8	8589934595
-9	17179869186
-10	8589934596
-
--- 生成唯一的行号
-> SELECT monotonically_increasing_id() as row_id, *
-  FROM large_table;
-
--- 为数据添加序列号
-> SELECT monotonically_increasing_id() as seq, name, age
-  FROM users
-  ORDER BY age;
-```
-
-#### 说明
-* monotonically_increasing_id 生成的 ID 具有以下特性：
-  * 唯一性：每个 ID 在结果集中唯一
-  * 单调性：ID 值单调递增（但不一定连续）
-  * 确定性：在相同的数据分布下，生成的 ID 相同
-* 在分布式环境中，ID 的生成方式：
-  * 每个分区分配一个 ID 范围
-  * 分区内的 ID 连续递增
-  * 不同分区的 ID 范围不重叠
-  * ID 的高位用于标识分区，低位用于标识分区内的行号
-* ID 的构成（64 位）：
-  * 高 33 位：分区 ID
-  * 低 31 位：分区内的行号
-  * 因此，每个分区最多可以有 2^31 - 1 行
-* 与 row_number() 的区别：
-  * monotonically_increasing_id() 在分布式环境中更高效
-  * row_number() 需要全局排序，开销较大
-  * monotonically_increasing_id() 不保证连续性
-* 注意事项：
-  * ID 不一定从 0 开始（在分布式环境中）
-  * ID 之间可能有间隙
-  * 不应依赖 ID 的具体值，只能依赖其唯一性和单调性
-  * 相同的查询在不同的执行中可能生成不同的 ID（如果数据分布改变）
-* 该函数常用于：

-### PMOD 函数
-```
-pmod(expr1, expr2)
-```
-#### 功能描述
-PMOD 函数用于计算两个数值表达式之间的模运算结果，并返回结果的正值。具体来说，该函数首先计算 `expr1 % expr2`，然后将结果与 `expr2` 相加，最后再对 `expr2` 取模，从而确保返回值始终为正数。这一特性使得 PMOD 函数在处理循环或周期性问题时非常有用。
-
-#### 参数说明
-* **expr1**：一个数值类型的表达式，可以是 float、double、decimal、tinyint、smallint、int 或 bigint 类型。
-* **expr2**：与 expr1 类型相同的数值表达式。
-
-#### 返回值
-返回类型与输入参数 expr1 和 expr2 相同。
-
-#### 使用示例
-1.  计算 2 与 1.8 之间的模运算结果：
-    ```sql
-SELECT pmod(2, 1.8); -- 结果为 0.2
-```
-2.  计算 -10 与 3 之间的模运算结果，并确保返回正值：
-    ```sql
-SELECT pmod(-10, 3); -- 结果为 2
-```
-3.  对于整数和小数的混合计算，PMOD 函数同样适用：
-    ```sql
-SELECT pmod(5.5, 3); -- 结果为 2.5
-```
-4.  在处理周期性问题时，比如计算一天中剩余的时间，可以使用 PMOD 函数：
-    ```sql
-SELECT pmod(12, 24); -- 结果为 12，表示从 12:00 开始还有 12 小时

-   ```sql
-   SELECT POW(10, 5) / POW(2, 3); -- 结果为 12500.0 
-   ```
-
-#### 注意事项
-* 当 `expr2` 为负数时，表示求解 `expr1` 的负指数幂。例如，`POW(2, -3)` 计算的是 1/(2³)。
-* 当 `expr2` 为 0 时，对于任何非零的 `expr1`，结果都是 1。如果 `expr1` 为 0，则结果未定义。
-* 当 `expr1` 为负数且 `expr2` 为非整数时，结果可能是一个复数。在某些数据库系统中，这可能导致错误或返回特定的复数表示。请根据所使用的数据库系统查阅相关文档以确保正确处理。

-4
-
-> SELECT shiftleft(8, 2);
-32
-
-> SELECT shiftleft(0, 2);
-0
-
--- bigint 类型左移
-> SELECT shiftleft(1L, 2);
-4
-
-> SELECT shiftleft(8L, 2);
-32
-
--- NULL 处理
-> SELECT shiftleft(NULL, 2);
-NULL
-
-> SELECT shiftleft(1, NULL);
-NULL
-
--- 负数左移
-> SELECT shiftleft(-4, 2);
--16
-
--- 实际应用：计算 2 的幂
-> SELECT shiftleft(1, 10);  -- 2^10 = 1024
-1024
-```
-
-#### 说明
-* 左移 n 位等价于乘以 2^n
-* 对于正数：shiftleft(x, n) = x * 2^n
-* 对于负数，左移操作保留符号位。
-* 移位操作可能导致溢出：
-  * int 类型范围：-2,147,483,648 到 2,147,483,647
-  * bigint 类型范围：-9,223,372,036,854,775,808 到 9,223,372,036,854,775,807
-* 如果移位后的结果超出类型范围，会发生溢出（结果不可预测）。
-* 移位操作是位运算，性能优于乘法运算
-* 常用于：
-  * 快速计算 2 的幂次
-  * 位标志和位掩码操作
-  * 数据编码和解码
-* 相关函数：
-  * shiftright - 算术右移（保留符号位）
-  * shiftrightunsigned - 逻辑右移（不保留符号位）

-   ```sql
-   > SELECT array(1.5, 2.3, 4.7);
-   [1.5, 2.3, 4.7]
-   ```
-3. 创建一个包含字符串的数组：
-   ```sql
-   > SELECT array('apple', 'banana', 'cherry');
-   ['apple', 'banana', 'cherry']
-   ```
-4. 隐式类型转换示例：
-   ```sql
-   > SELECT array(1, '2', 3.0);
-   [1.0,2.0,3.0] -- 字符串 '2' 被隐式转换为数值类型
-   ```
-5. 使用 `array` 函数与 `SELECT` 语句结合，从表中选择多个字段并创建数组：
-   ```sql
-   > SELECT array(column1, column2, column3) FROM my_table;
-   ```
-   假设 `my_table` 包含三列 `column1`, `column2`, `column3`，该查询将为每一行返回一个包含这三列值的数组。
-
-#### 注意事项
-- 当传入的参数类型不一致时，系统将尝试进行隐式类型转换。如果转换失败，将元素返回为 null。
-- 在创建数组时，请确保所有元素的类型兼容，以避免不必要的类型转换和潜在的性能损失。
-
-通过使用 `array` 函数，您可以轻松地在 SQL 查询中创建和管理数组数据，从而更灵活地处理和分析数据。

-   ```
-   上述示例中，两个数组长度相同，直接合并生成一个新的数组。
-
-2. 不等长数组合并：
-   ```sql
-   SELECT arrays_zip(array(1, 2, 3), array(4, 5));
-   ```
-   结果：
-   ```json
-    [{"0":1,"1":4},{"0":2,"1":5},{"0":3,"1":null}]
-   ```
-   在这个示例中，两个数组长度不同，合并时较短的数组后面的元素会被填充为 null。
-
-3. 多数组合并：
-   ```sql
-   SELECT arrays_zip(array(1, 2), array(4, 5), array('a', 'b'));
-
-   ```
-   结果：
-   ```json
-    [{"0":1,"1":4,"2":"a"},{"0":2,"1":5,"2":"b"}]
-   ```
-   本示例中，三个数组被合并成一个新数组，每个元素都是一个包含三个字段的结构体。

-`MAP_CONCAT` 函数用于将多个 `map` 类型参数中的键值对合并到一起，形成一个全新的 `map`。这个函数在处理多个数据源并需要将它们的数据整合到一个单一的数据结构时非常有用。
-
-#### 语法格式
-```
-MAP_CONCAT(map1, map2, ..., mapN)
-```
-
-#### 参数说明
-- `map1` ~ `mapN`: 输入的 `map` 类型参数，可以是两个或更多，每个参数都是一个 `map<K, V>` 类型，其中 `K` 表示键的类型，`V` 表示值的类型。
-
-#### 返回类型
-返回一个新的 `map<K, V>` 类型，其中包含了所有输入 `map` 参数中的键值对。
-
-#### 使用示例
-1. 基础使用：
-   ```sql
-   SELECT MAP_CONCAT(map('key1', 'value1'), map('key2', 'value2'));
-   // 返回结果：{"key1":"value1","key2":"value2"}
-   ```
-   在这个例子中，两个 `map` 被合并成一个，包含了两个键值对。
-
-2. 多个参数合并：
-   ```sql
-   SELECT MAP_CONCAT(map('a', 1), map('b', 2), map('c', 3));
-   // 返回结果：{"a":1,"b":2,"c":3}
-   ```
-   三个 `map` 被合并成一个，形成了一个包含三个键值对的新 `map`。
-
-3. 重复键的处理：
-   ```sql
-   SELECT MAP_CONCAT(map('key', 'original'), map('key', 'override'));
-   // 返回结果：{"key":"override"}
-   ```
-   当多个 `map` 包含相同的键时，后面的 `map` 中的值会覆盖前面的值。

-### MAP\_FROM\_ENTRIES 函数
-
-#### 功能描述
-`MAP_FROM_ENTRIES` 函数用于从数组中创建一个 map 类型。输入的数组元素需要符合 `map_entries` 函数的格式，即每个元素都是一个包含 `key` 和 `value` 属性的结构体。
-
-#### 参数说明
-* `array`: 输入参数，类型为 `array<struct<key:K, value:V>>`，表示包含多个结构体的数组，每个结构体具有 `key` 和 `value` 两个属性。
-
-#### 返回结果
-返回一个 `map<K, V>` 类型的结果，其中 `K` 表示 key 的类型，`V` 表示 value 的类型。
-
-#### 使用示例
-1. 创建一个包含两个元素的数组，每个元素都是一个结构体，结构体中包含两个属性：`key` 和 `value`。
-```sql
-SELECT MAP_FROM_ENTRIES(ARRAY(
-NAMED_STRUCT('key',1, 'value','a'),
-NAMED_STRUCT('key',2, 'value','b')
-));
-
-```
-返回结果：
-```
-{
-  1:"a",
-  2:"b"
-}
-```
-
-2. 创建一个包含三个元素的数组，元素类型为结构体，结构体中包含不同类型的 key 和 value。
-```sql
-SELECT MAP_FROM_ENTRIES(ARRAY(
-NAMED_STRUCT('key',1, 'value','apple' ),
-NAMED_STRUCT('key',2, 'value','carrot'),
-NAMED_STRUCT('key',3, 'value','dog')
-));
-
-
-```
-返回结果：
-```
-{
-  1:"apple",
-  2:"carrot",
-  3:"dog"
-}
-```
-
-注意：在上述示例中，`extra` 属性不会包含在最终的 map 中，因为我们只关心 `key` 和 `value` 属性。
-
-#### 注意事项
-* 输入数组中的每个结构体必须具有 `key` 和 `value` 两个属性，否则会导致函数执行失败。
-* key 的类型需要唯一，不能有重复的 key 值，否则后面的 key 值会覆盖前面的 key 值。

-### SEQUENCE 函数
-
-#### 概述
-SEQUENCE 函数用于生成一个序列，该序列从起始值（start）开始，到结束值（stop）结束，并按照指定的步长（step）递增。生成的序列包含起始值和结束值。如果未提供步长参数，系统会根据起始值和结束值的大小关系自动选择默认步长。
-
-#### 功能
-- 当起始值小于结束值时，若未指定步长，默认步长为 1。
-- 当起始值大于结束值时，若未指定步长，默认步长为 -1。
-- 支持整数和时间类型的参数。
-
-#### 参数
-- start (tinyint/smallint/int/bigint): 序列的起始值。
-- stop (tinyint/smallint/int/bigint): 序列的结束值。
-- step (tinyint/smallint/int/bigint): 序列中相邻两个元素之间的差值（步长）。可选参数。若未指定，默认值为 1 或 -1，具体取决于起始值和结束值的大小关系。
-
-#### 返回结果
-返回一个与参数类型相同的数组。
-
-#### 使用示例
-1. 生成整数序列：
-   ```sql
-   SELECT sequence(-2, 2); -- 结果：[-2, -1, 0, 1, 2]
-   SELECT sequence(2, -2); -- 结果：[2, 1, 0, -1, -2]
-   SELECT sequence(-2, 2, 3); -- 结果：[-2, 1]
-   ```
-   
-2. 生成时间序列：
-   ```sql
-   SELECT sequence(timestamp '2020-10-10 00:00:00', timestamp '2020-10-15 00:00:00', interval '1 12:00:00' day to second);
-   -- 结果：[2020-10-10 00:00:00, 2020-10-11 12:00:00, 2020-10-13 00:00:00, 2020-10-14 12:00:00]
-   ```
-
-#### 注意事项
-- 当起始值和结束值相等时，无论步长为何值（只要不为 0），生成的序列都仅包含一个元素，即起始值本身。
-- 当步长为 0 时，SEQUENCE 函数将报错。

-### SLICE 函数
-
-#### 概述
-SLICE 函数用于从数组中提取一个子集。根据指定的起始位置（start）和所需元素数量（limit），函数将返回一个包含至多 limit 个元素的新数组。如果指定的起始位置为负数，则从数组末尾开始计算位置。
-
-#### 语法
-```
-slice(array, start, limit)
-```
-
-#### 参数
-- `array`: `array<T>` 类型，表示需要进行切片操作的数组。
-- `start`: int 类型，表示切片开始的位置。从 1 开始计数。如果 start 为负数，则从数组末尾开始计算。
-- `limit`: int 类型，表示需要提取的元素数量。
-
-#### 返回结果
-返回一个新的数组，包含从 start 位置开始的最多 limit 个元素。
-
-#### 使用示例
-
-1. 提取数组中的前两个元素：
-```
-SELECT slice(array(1, 2, 3, 4), 1, 2);
-```
-结果：
-```
-[1, 2]
-```
-
-2. 从数组的第三个元素开始提取一个元素：
-```
-SELECT slice(array(1, 2, 3, 4), 3, 1);
-```
-结果：
-```
-[3]
-```
-
-
-#### 注意事项
-- 如果 start 和 limit 的值超出数组范围，函数将返回一个空数组。

-
-### 概述
-`struct_insert` 函数用于在结构体（struct）中插入一个新的字段。新字段的名称由 `name` 参数指定，其值为 `expr` 参数指定。可选的 `indexToInsert` 参数用于指定插入位置。如果未指定 `indexToInsert` 或其值为 0，则新字段将插入到结构体的末尾。如果 `indexToInsert` 为 1，则新字段将插入到第一个字段之后，以此类推。
-
-### 功能
-- 向结构体中添加新的字段。
-- 通过 `indexToInsert` 参数控制新字段的插入位置。
-
-### 参数
-- `struct`: 需要插入新字段的结构体。
-- `name`: 新字段的名称，必须为字符串常量。
-- `expr`: 新字段的值，可以是任意类型的数据。
-- `indexToInsert`: （可选）指定新字段的插入位置，为整数常量，默认值为 0。
-
-### 返回结果
-返回一个新的结构体，其结构取决于插入的键值对和指定的插入位置。
-
-### 使用示例
-1. 向结构体末尾添加新字段：
-   ```sql
-   SELECT struct_insert(named_struct('a', 1, 'b', 2), 'x', 'hello');
-   -- 结果：{"a":1, "b": 2, "x":"hello"}
-   ```
-
-2. 向结构体头部插入新字段：
-   ```sql
-   SELECT struct_insert(named_struct('a', 1, 'b', 2), 'x', 'hello', 0);
-   -- 结果：{"x":"hello", "a":1, "b": 2}
-   ```
-
-3. 在第一个字段之后插入新字段：
-   ```sql
-   SELECT struct_insert(named_struct('a', 1, 'b', 2), 'x', 'hello', 1);
-   -- 结果：{"a":1, "x":"hello", "b": 2}
-   ```
-
-4. 在第二个字段之前插入新字段：
-   ```sql
-   SELECT struct_insert(named_struct('a', 1, 'b', 2), 'y', 3, 2);
-   -- 结果：{"a":1, "y":3, "b": 2, "x": "hello"}
-   ```
-
-5. 向包含嵌套结构体的结构体中插入新字段：
-   ```sql
-   SELECT struct_insert(named_struct('outer', named_struct('inner', 'value')), 'newField', 'newValue');
-   -- 结果：{"outer":{"inner":{"value"},"newField":"newValue"}}
-   ```
-
-### 注意事项
-- 请确保 `name` 参数为字符串常量，否则可能导致函数执行失败。
-- `indexToInsert` 参数的有效范围为 0 到结构体字段数量（包含）。超出此范围的值将导致函数执行失败。
-- 当插入位置与现有字段冲突时（例如，尝试在已存在的字段位置插入新字段），函数将返回错误。

-### STRUCT_UPDATE 函数
-
-#### 功能描述
-`STRUCT_UPDATE` 函数用于更新一个结构体（struct）中的指定字段（field），将给定字段名对应的值替换为新的表达式值（expr）。需要注意的是，新值的类型可以与原值不同。
-
-#### 参数说明
-* `struct`: 需要更新的结构体（struct）。
-* `name`: 待更新字段的名称，必须为字符串常量。
-* `expr`: 用于替换原字段值的新表达式，可以是任意类型。
-
-#### 返回结果
-返回一个新的结构体（struct），其结构与原结构体相同，但已更新指定字段的值。
-
-#### 使用示例
-1. 假设我们有一个结构体 `s1`，包含两个字段：`"a"` 的值为 1，`"b"` 的值为 2。我们可以使用 `STRUCT_UPDATE` 函数将字段 `"a"` 的值更新为字符串 `"hello"`：
-```sql
-SELECT STRUCT_UPDATE(named_struct('a', 1, 'b', 2), 'a', 'hello');
-```
-执行结果为：
-```json
-{"a":"hello", "b":2}
-```
-
-2. 同样，我们也可以将字段 `"b"` 的值更新为字符串 `"hello"`：
-```sql
-SELECT STRUCT_UPDATE(named_struct('a', 1, 'b', 2), 'b', 'hello');
-```
-执行结果为：
-```json
-{"a":1, "b":"hello"}
-```
-
-3. 除了字符串，我们还可以使用其他类型的表达式来更新字段值，例如将字段 `"a"` 的值更新为当前时间戳：
-```sql
-SELECT STRUCT_UPDATE(named_struct('a', 1, 'b', 2), 'a', TIMESTAMP "2023-04-01 12:00:00");
-```
-执行结果为：
-```json
-{"a":2023-04-01 12:00:00, "b":2}
-```
-
-通过以上示例，您可以看到 `STRUCT_UPDATE` 函数在更新结构体字段时非常灵活且易于使用。

-# TRANS\_ARRAY 函数
-
-## 函数描述
-
-`TRANS_ARRAY` 是一个用户自定义表值函数（UDTF），用于将一行数据转换为多行数据。它将列中存储的以固定分隔符格式分隔的数组转换为多行，实现"行转列"的数据变换。该函数特别适合处理那些将多个值存储在单个字符串字段中的数据结构。
-
-### 核心特性
-
-* **行转列转换**：将单行中用分隔符分隔的多个值拆分为多行
-* **灵活的 Key 列**：支持指定一个或多个列作为 Key，这些列不参与拆分
-* **自动补全**：当数组长度不相等时，自动用 NULL 填充较短的数组
-* **分隔符可配置**：支持任意字符串作为分隔符
-
-## 语法
-
-```sql
-trans_array(<num_keys>, <separator>, <key1>, <key2>, ..., <col1>, <col2>, <col3>)AS (<key1>, <key2>, ..., <col1>, <col2>)
-```
-
-## 参数说明
-
-| 参数              | 类型     | 必填 | 说明                                                              |
-| ----------------- | -------- | ---- | --------------------------------------------------------------- |
-| num\_keys         | BIGINT   | 是   | 转置时作为 Key 的列的个数。必须为常量，值必须 ≥ 0。Key 列必须位于所有待转置列之前。                 |
-| separator         | STRING   | 是   | 用于将字符串拆分成多个元素的分隔符。必须为常量，不能为空字符串，否则返回错误。                          |
-| key1, key2, ...   | 任意类型 | 是   | 转置时作为 Key 的列，个数由 num\_keys 指定。Key 列在结果中保持原有数据类型。                 |
-| col1, col2, ...   | STRING   | 是   | 要转为行的数组列。这些列必须为 STRING 类型，存储的内容是字符串格式的数组，例如 `item1;item2;item3`。 |
-
-### 特殊说明
-
-* **Key 列的作用**：Key 列用于分组和标识，拆分过程中 Key 列的值保持不变
-
-* **转置列要求**：Key 之后的所有列都视为待转置的数组列，必须为 STRING 类型
-
-* **输出行数**：以长度最长的数组为准，其他较短数组不足的位置用 NULL 填充。
-
-* **输出类型**：Key 列保持原有类型，其余所有列为 STRING 类型
-
-
-## 返回值
-
-返回转置后的多行数据，其中：
-
-* Key 列的数据类型保持不变
-* 转置后的列全部为 STRING 类型
-* 新的列名由 AS 子句指定
-
-## 使用示例
-
-**示例 1：单 Key 的基础转置**
-
-场景描述：用户登录表中，每个用户有多条登录 IP 和时间信息，存储为用分隔符分隔的字符串。需要将其拆分为多行以便于分析。

-```
-
-SQL 语句：
-
-```sql
-SELECT  trans_array(1, ',', login_id, login_ip, login_time)  AS (login_id, login_ip, login_time)FROM test_user_login;
-```
-
-执行结果：
-
-| login\_id | login\_ip     | login\_time    |
-| --------- | ------------- | -------------- |
-| wangwangA | 192.168.0.1   | 20120101010000 |
-| wangwangA | 192.168.0.2   | 20120102010000 |

-* `num_keys=1` 表示只有 `login_id` 列作为 Key。
-* `separator=','` 指定逗号作为分隔符。
-* 每个用户的登录记录被拆分为单独的行。
-* `login_id` 保持不变，作为分组标识。
-
-**示例 2：多 Key 的转置**
-
-场景描述：用户信息表中包含用户 ID、姓名以及多条登录 IP 和时间记录。现需使用两个 Key 列进行转置。
-
-原始数据表：`test_user_info`
-
-```
-CREATE TABLE test_user_info ( id INT, name STRING, login\_ip STRING, login\_time STRING);
-INSERT INTO test_user_info VALUES(1, 'Tom', '192.168.100.1,192.168.100.2', '20211101010101,20211101010102'),(2, 'Jerry', '192.168.100.3,192.168.100.4', '20211101010103,20211101010104');
-```
-
-SQL 语句：

-| 2  | Jerry | 192.168.100.4 | 20211101010104 |
-
-结果说明：
-
-* `num_keys=2` 表示将 `id` 和 `name` 两列作为 Key。
-* 两个 Key 列在结果中保持不变。
-* 登录记录根据 Key 列的值保持分组关系。
-
-**示例 3：不等长数组处理（自动补 NULL）**
-
-场景描述：用户兴趣表中，不同用户拥有不同数量的爱好和运动项目。本示例展示如何处理数组长度不相等的情况。
-
-原始数据表：`test_unequal_array`
-
-```
-CREATE TABLE test_unequal_array ( user_id STRING, hobbies STRING, sports STRING);
-INSERT INTO test_unequal_array VALUES('user1', 'reading,coding', 'basketball,tennis,swimming');
-
-```
-
-SQL 语句：
-
-```sql
-SELECT  trans_array(1, ',', user_id, hobbies, sports)  AS (user_id, hobbies, sports)FROM test_unequal_array;
-```
-
-执行结果：
-
-| user\_id | hobbies | sports     |
-| -------- | ------- | ---------- |
-| user1    | reading | basketball |

-## MATCH\_PHRASE
-
-```SQL
-MATCH_PHRASE(inverted_column,query, option) 
-```
-
-### 功能说明
-
-只有构建倒排索引的列才能使用该函数，在match\_all的基础上，匹配的结果顺序要和query分词结果的顺序要一致且连续，忽略大小写。然后会将query根据分词构建查询，最终返回查询结果。比如查询字符串是“Microsoft Azure Party”，被分析器分词之后，产生三个小写的单词：microsoft，azure和party，然后根据分析的结果构造一个布尔查询，默认情况下，引擎内部执行的查询逻辑是：只要eventname字段值中包含所有microsoft、azure或party，并且顺序microsoft、azure或party，是那么返回该行数据
-
-### 参数说明
-
-* **inverted\_column**: 用于构建倒排索引的列。
-* **query**: 您想要搜索的文本字符串。
-* **option**: 此参数是必填项，用于指定分词设置。它必须与用于构建倒排索引的列使用相同的分词方法。支持`auto`参数，该参数会自动与`inverted_column`中的分词设置进行匹配，例如：`map('analyzer', 'auto')`。

-
-#### 语法
-```
-BINARY(str)
-```
-#### 参数
-- `str`: 需要转换的字符串类型的数据。
-
-#### 返回结果
-- 返回一个二进制数据类型的字节流。
-
-#### 使用示例
-1. 将字符串 "hello" 转换为二进制形式：
-   ```sql
-   SELECT BINARY('hello');
-   ```
-   结果：
-   ```
-    [68 65 6c 6c 6f] 
-   ```
-2. 将一个包含特殊字符的字符串 "élle!" 转换为二进制形式：
-   ```sql

-   SELECT BINARY('你好');
-   ```
-   结果：
-   ```
-   [e4 bd a0 e5 a5 bd]
-   ```
-
-#### 注意事项
-- 当输入的字符串包含非ASCII字符时，`BINARY()` 函数会对其进行编码转换，以便在二进制形式中正确表示。
-- 在处理二进制数据时，需要注意字符集和校对规则的设置，以确保数据的正确性和一致性。
-
-通过使用 `BINARY()` 函数，您可以方便地在数据库中存储和操作二进制数据，例如图像、音频和视频文件等。

-```
-CHAR(code)
-```
-
-#### 参数
-- `code`: 整数，表示要转换的字符码。
-
-#### 返回结果
-- 返回一个字符串，表示转换后的字符。
-
-#### 使用示例
-
-1. 将 ASCII 码转换为对应的字符：
-   ```sql
-   SELECT CHAR(ASCII('中')), LENGTH(CHAR(ASCII(''))), CHAR(ASCII('a'));
-   ```
-   结果：
-   ```
-   中	1	a
-   ```
-
-2. 将 Unicode 码转换为对应的字符：
-   ```sql
-   SELECT CHAR(20013) AS result;
-   ```
-   结果：
-   ```
-   转换结果	中
-   ```
-
-3. 转换非法 Unicode 码：
-   ```sql
-   SELECT CHAR(-1) AS result;
-   ```
-   结果：
-（空字符串）
-
-4. 转换多个字符码：

-## 功能概述
-
-`FORMAT_STRING` 是一个 SQL 函数，用于格式化字符串。它基于 `printf` 样式的格式字符串生成格式化后的字符串。此函数使用 `java.util.Formatter` 类，利用 `Locale.US` 进行格式化。
-
-## 语法
-
-```SQL
-FORMAT_STRING(strfmt [, obj1 [, ...]])
-```
-
-## 参数说明
-
-* **strfmt**: 一个 `STRING` 类型的表达式，定义了字符串的格式。这应该包含格式化指令，如 `%d`、`%s` 等。
-* **obj1, ...**: 一个或多个 `STRING` 或数值类型的表达式，这些表达式将被格式化并插入到 `strfmt` 中相应的位置。
-
-## 返回结果
-
-该函数返回一个 `STRING` 类型的值，表示格式化后的字符串。
-
-## 示例
-
-示例 1: 基本使用
-
-```SQL
-SELECT FORMAT_STRING('Hello World %d %s', 100, 'days') as res;
-+----------------------+
-|         res          |
-+----------------------+
-| Hello World 100 days |
-+----------------------+
-```
-
-示例 2: 使用数值参数
-
-```SQL
-SELECT FORMAT_STRING('The square of %d is %d', 5, 5*5) as res;
-+-----------------------+
-|          res          |
-+-----------------------+
-| The square of 5 is 25 |
-+-----------------------+
-```
-
-示例 3: 使用多个参数
-
-```SQL
-SELECT FORMAT_STRING('Name: %s, Age: %d, Location: %s', 'Alice', 30, 'Wonderland') as res;
-+--------------------------------------------+
-|                    res                     |
-+--------------------------------------------+
-| Name: Alice, Age: 30, Location: Wonderland |
-+--------------------------------------------+

-### INSTR 函数
-```sql
-instr(str, substr)
-```
-#### 功能描述
-INSTR 函数用于查找指定子字符串（substr）在给定字符串（str）中第一次出现的位置。当 substr 在 str 中被找到时，返回其起始位置的整数索引（从 1 开始计数）；若未找到，则返回 0。
-
-#### 参数说明
-- str: 待搜索的字符串。
-- substr: 需要查找的子字符串。
-
-#### 返回结果
-返回一个整数，表示 substr 在 str 中第一次出现的位置。如果 substr 未在 str 中出现，则返回 0。
-
-#### 使用示例
-1.  查询子字符串 "World" 在 "HelloWorld" 中的位置：
-    ```sql
-SELECT INSTR('HelloWorld', 'World'); -- 结果为：6
-```
-2.  查询子字符串 "Java" 在 "HelloWorld" 中的位置（预期未找到，返回 0）：
-    ```sql
-SELECT INSTR('HelloWorld', 'Java'); -- 结果为：0
-```
-3.  计算子字符串 "or" 在 "HelloWorld" 中的起始位置：
-    ```sql
-SELECT INSTR('HelloWorld', 'or'); -- 结果为：7
-```
-4.  在一个更长的文本中查找子字符串 "Program" 的位置：
-    ```sql
-SELECT INSTR('Programming in C language is fun', 'Program'); -- 结果为：1
-```
-5.  当 substr 为空字符串时，返回 1，因为空字符串被视为存在于任何字符串的开头。
-    ```sql
-SELECT INSTR('HelloWorld', ''); -- 结果为：1
-```
-#### 注意事项
-- 如果 str 或 substr 为 NULL，则 INSTR 函数返回 NULL。
-- 搜索是区分大小写的，即 'Hello' 和 'hello' 被视为不同的字符串。
-- 若要执行不区分大小写的搜索，可先使用 UPPER 或 LOWER 函数转换 str 和 substr 为同一大小写形式，然后再进行比较。
-
-通过以上示例和说明，您可以更好地理解 INSTR 函数的用法和功能。在实际应用中，您可以根据需要灵活地使用此函数来查找特定子字符串的位置。

-   ```
-   
-2. 删除字符串左侧的特定字符：
-   ```sql
-   SELECT LTRIM('HelloWorld', 'He');
-   -- 结果：World
-   ```
-   
-3. 删除字符串左侧的多个字符（字符集）：
-   ```sql
-   SELECT LTRIM('!!!HelloWorld!!!', '!');
-   -- 结果：HelloWorld
-   ```
-   
-4. 当 `trimStr` 为空字符串时，不会对 `str` 进行任何操作：
-   ```sql
-   SELECT LTRIM('Hello', '');
-   -- 结果：Hello
-   ```
-   
-5. 如果 `trimStr` 中包含 `str` 中不存在的字符，LTRIM 函数仍会删除 `str` 左侧的空格：
-   ```sql
-   SELECT LTRIM('Hello', 'abc');
-   -- 结果：Hello
-   ```
-
-#### 注意事项
-- 当 `trimStr` 参数为空或仅包含空格时，LTRIM 函数的行为与 `LTRIM` 函数的默认行为相同，即删除字符串左侧的所有空格。
-- 如果 `trimStr` 参数中包含非打印字符或特殊字符，这些字符也会被用于去除 `str` 左侧的字符。

-### MD5函数
-
-#### 简介
-
-MD5函数用于计算给定字符串的MD5散列值。MD5是一种广泛使用的哈希函数，它可以将任意长度的数据映射为固定长度（128位）的散列值。MD5散列值通常用于验证数据的完整性。
-
-#### 语法
-
-```
-md5(expr)
-```
-
-#### 参数
-
-* `expr`: 需要计算MD5值的字符串、字符或变长字符数据类型。
-
-#### 返回结果
-
-返回一个字符串，表示计算得到的MD5散列值。
-
-#### 使用示例
-
-1. 计算一个简单字符串的MD5值：
-
-```
-SELECT md5('hello')as res;
-+----------------------------------+
-|               res                |
-+----------------------------------+
-| 5d41402abc4b2a76b9719d911017c592 |
-+----------------------------------+
-```
-
-2. 计算一个包含特殊字符的字符串的MD5值：
-
-```
-SELECT md5('Hello, World!') as res;
-+----------------------------------+
-|               res                |
-+----------------------------------+
-| 65a8e27d8879283831b664bd8b7f0ad4 |
-+----------------------------------+
-```
-
-3. 计算一个中文字符串的MD5值：
-
-```
-SELECT md5('你好，世界！') as res;
-+----------------------------------+
-|               res                |
-+----------------------------------+
-| 5082079d92a8ef985f59e001d445ff20 |
-+----------------------------------+
-```
-
-4. 计算一个包含数字的字符串的MD5值：
-
-```
-SELECT md5('12345');
-+----------------------------------+
-|               res                |
-+----------------------------------+
-| 827ccb0eea8a706c4c34a16891f84e7b |
-+----------------------------------+
-```
-
-#### 注意事项
-
-* MD5散列值是不可逆的，即无法从散列值反推出原始数据。

-### 函数名称
-OCTET_LENGTH
-
-### 功能描述
-OCTET_LENGTH 函数用于计算字符串（string）或二进制数据（binary）的字节长度。该函数在处理文本数据时非常有用，尤其是在需要确定数据大小或进行字符编码转换时。
-
-### 语法
-```
-OCTET_LENGTH(expr)
-```
-其中，`expr` 是一个字符串或二进制数据类型的表达式。
-
-### 参数
-- `expr`: 需要计算字节长度的字符串或二进制数据。
-
-### 返回结果
-返回一个整数，表示输入数据的字节长度。
-
-### 使用示例
-1. 计算英文字符串的字节长度：
-   ```sql
-   SELECT OCTET_LENGTH('HelloWorld'); -- 结果为 10
-   ```
-   上述示例中，字符串 "HelloWorld" 包含 10 个字符，因此返回的字节长度为 10。
-
-2. 计算中文字符串的字节长度：
-   ```sql
-   SELECT OCTET_LENGTH('你好'); -- 结果为 6
-   ```
-   由于中文字符在 UTF-8 编码下通常占用 3 个字节，字符串 "你好" 包含 2 个中文字符，因此返回的字节长度为 6。
-
-3. 计算二进制数据的字节长度：
-   ```sql
-   SELECT OCTET_LENGTH(X'48656C6C6F20576F726C64'); -- 结果为 20
-   ```
-   上述示例中，十六进制字符串 "48656C6C6F20576F726C64" 解码后对应于 ASCII 编码的字符串 "Hello World"，占用 11 个字节。
-
-4. 在查询中使用 OCTET_LENGTH 函数：
-   ```sql
-   SELECT username, OCTET_LENGTH(password) as password_length
-   FROM users;
-   ```
-   在此示例中，我们从用户表中选择用户名和密码的字节长度。这可以帮助我们了解数据存储大小或密码的复杂度（结合其他因素）。
-
-### 注意事项
-- 当处理多字节字符集（如 UTF-8）时，字符的实际字节长度可能与字符数不同。
-- 在比较字符串长度时，务必注意字符编码和字节顺序的影响。

-### RLIKE 函数
-#### 概述
-RLIKE 函数用于检查一个字符串（str）是否符合给定的正则表达式（regex）。如果符合，则返回 true，否则返回 false。该函数使用 [re2](https://github.com/google/re2) 正则表达式引擎进行匹配。
-
-#### 语法
-```
-str [not] rlike regex
-
-rlike(str, regex)
-```
-#### 参数
-* str (string)：待匹配的字符串。
-* regex (string)：正则表达式。请注意，由于 SQL 解析器会对字符串常量进行转义，因此在使用常量指定正则表达式时需要使用双反斜杠（例如：'^\\\\abc$'）。
-
-#### 返回结果
-返回一个布尔值（boolean），表示 str 是否符合 regex。
-
-#### 使用示例
-1. 检查字符串 "100-500" 是否符合正则表达式 `\d+-\d+`（数字加短横线加数字）：
-```sql
-SELECT '100-500' RLIKE '\d+-\d+';
-```
-结果：
-```
-true
-```
-
-2. 使用函数形式检查字符串 "100-500" 是否符合正则表达式 `\d+-\d+`：
-```sql
-SELECT RLIKE('100-500', '\d+-\d+');
-```
-结果：
-```
-true
-```
-
-3. 检查字符串 "\\abc" 是否符合正则表达式 `^\\\\abc$`（匹配以 "abc" 开头和结尾的字符串，正则表达式本身可能包含反斜杠进行转义）：
-```sql
-SELECT RLIKE('\\abc', '^\\\\abc$');
-```
-结果：
-```
-true
-```
-
-4. 检查字符串 "abc" 是否**不符合**正则表达式 `^\\d+$`（以数字开头和结尾的字符串）：
-```sql
-SELECT 'abc' RLIKE '^\\d+$';
-```
-结果：
-```
-false
-```
-
-5. 使用 "not" 关键字检查字符串 "123" 是否**不符合**正则表达式 `\d+`（包含数字的字符串）：

-
-``` sql
-rpad(str, len[, pad])
-```
-
-#### 功能描述
-RPAD 函数用于对字符串进行右侧填充。它在给定的字符串 `str` 右侧添加指定的 `pad` 字符串，直到总长度达到 `len`。如果 `len` 小于字符串 `str` 的长度，函数将截断原字符串至 `len` 长度并返回。若 `len` 小于 1，函数返回空字符串。若未指定 `pad` 字符串，则默认使用空格字符（' '）作为填充字符。
-
-#### 参数说明
-- `str`: 输入的字符串。
-- `len`: 目标总长度。
-- `pad` (可选): 用于填充的字符串，默认为一个空格字符（' '）。
-
-#### 返回结果
-返回一个新的字符串，长度为 `len`，右侧填充了 `pad` 字符串。
-
-#### 使用示例
-1. 基础用法：在字符串右侧添加指定的填充字符。
-   ```sql
-   > SELECT rpad('hello', 10, '123');
-   hello12312  
-   ```
-
-2. 当 `len` 大于 `str` 长度时，使用默认填充字符（空格）。
-   ```sql
-   > SELECT rpad('world', 12);
-   world        
-   ```
-
-3. 当 `len` 小于 `str` 长度时，截断原字符串至 `len` 长度。
-   ```sql
-   > SELECT rpad('hello world', 5);
-   hello
-   ```
-
-4. 当 `len` 小于 1 时，返回空字符串。
-   ```sql
-   > SELECT rpad('test', 0);
-   
-   ```
-
-5. 使用自定义的填充字符。
-   ```sql
-   > SELECT rpad('abc', 8, '##');
-   abc#####
-   ```
-
-#### 注意事项
-- 当 `pad` 字符串长度大于 `len` 减去 `str` 长度时，`pad` 字符串将被截断以适应目标长度。
-- 如果 `pad` 字符串为空，将使用单个空格字符作为填充字符。
-
-通过使用 RPAD 函数，您可以轻松地对字符串进行格式化和对齐操作，以满足不同的数据处理需求。

-### 函数名称
-`translate` 函数
-
-### 功能描述
-`translate` 函数用于将输入字符串 `str` 中的某些字符根据指定的替换规则进行转换。具体来说，它会将 `str` 中的字符与 `from` 参数中的字符集合进行匹配，并将匹配到的字符替换为 `to` 参数中对应位置的字符。如果 `from` 中的某个字符在 `to` 中没有对应的替换字符，则在结果字符串中删除该字符。
-
-### 参数说明
-- `str` (string类型): 需要进行字符替换的原始字符串。
-- `from` (string类型): 包含需要被替换的字符集合。
-- `to` (string类型): 包含用于替换的字符集合。字符顺序应与 `from` 参数中的顺序相对应。
-
-### 返回值
-返回处理后的字符串。
-
-### 使用示例
-1. 假设我们有一个字符串 "HelloWorld"，我们想要将所有的 "l" 替换为 "b"，可以使用以下语句：
-   ```sql
-   SELECT translate('HelloWorld', 'l', 'b');
-   ```
-   执行结果为 "HebboWorbd"。
-
-2. 如果我们想要将字符串 "HelloWorld" 中的 "lo" 替换为 "ab"，可以使用以下语句：
-   ```sql
-   SELECT translate('HelloWorld', 'lo', 'ab');
-   ```
-   执行结果为 "HeaabWbrad"。
-
-3. 现在，如果我们想要将字符串 "HelloWorld" 中的 "l" 和 "o" 分别替换为 "b" 和 "n"，可以使用以下语句：
-   ```sql
-   SELECT translate('HelloWorld', 'lo', 'bn');
-   ```
-   执行结果为 "HebbnWnrbd"。
-
-4. 当 `to` 参数中的字符数量少于 `from` 参数时，多余的字符将被删除。例如，将字符串 "HelloWorld" 中的 "lo" 替换为 "a"，可以使用以下语句：
-   ```sql
-   SELECT translate('HelloWorld', 'lo', 'a');
-   ```
-   执行结果为 "HeaaWrad"。
-
-### 注意事项
-- 确保 `from` 和 `to` 参数中的字符数量相等，否则可能导致替换不完整或删除字符。
-- 如果 `to` 参数为NULL，将导致所有 `from` 返回结果也是NULL。
-- 该函数对大小写敏感，需要确保输入的字符大小写与实际需要替换的字符大小写一致。

-
-#### 功能描述
-
-`EXPLODE` 函数用于将数组或映射类型的表达式展开成多行。对于数组类型的输入，元素会被逐个展开成独立的行；对于映射类型的输入，键和值会被分别展开成多行。该函数可以直接使用，也可以与 `LATERAL VIEW` 搭配使用，以实现更复杂的数据处理。
-
-#### 参数说明
-
-* `expr`：输入的数组（`array<T>`）或映射（`map<K, V>`）表达式。
-
-#### 返回结果
-
-* 对于数组类型的输入，返回的结果中每个元素的类型为 `T`。
-* 对于映射类型的输入，返回的结果中包含两个列，分别表示键（`key`）和值（`value`），它们的类型分别为 `K` 和 `V`。
-
-#### 使用示例
-
-1. 将数组类型的表达式展开成多行：
-
-```sql
-SELECT explode(array(1, 2, 3));
-+-----+
-| col |
-+-----+
-| 1   |
-| 2   |
-| 3   |
-+-----+
-```
-
-2. 将映射类型的表达式展开成多行：
-
-```sql
-SELECT explode(map("a", 1, "b", 2, "c", 3));
-+-----+-------+
-| key | value |
-+-----+-------+
-| a   | 1     |
-| b   | 2     |
-| c   | 3     |
-+-----+-------+
-```
-
-3. 结合 LATERAL VIEW 使用，将数组类型的表达式展开成多行，并与原始数据关联：
-
-```sql
-SELECT vt.word, lv.ex
-FROM VALUES ('hello') AS vt(word) LATERAL VIEW explode(array(5, 6)) lv AS ex;
-+-------+----+
-| word  | ex |
-+-------+----+
-| hello | 5  |
-| hello | 6  |
-+-------+----+
-```
-
-4. 结合 LATERAL VIEW 使用，将映射类型的表达式展开成多行，并与原始数据关联：
-
-```sql
-SELECT vt.word, lv.key, lv.value
-FROM VALUES ('hello') AS vt(word) LATERAL VIEW explode(map("a", 1, "b", 2, "c", 3)) lv AS key, value;
-+-------+-----+-------+
-| word  | key | value |
-+-------+-----+-------+
-| hello | a   | 1     |
-| hello | b   | 2     |
-| hello | c   | 3     |
-+-------+-----+-------+
-```
-
-通过以上示例，您可以看到 `EXPLODE` 函数在处理数组和映射类型数据时的灵活性和实用性。在实际应用中，您可以根据需要对输入数据进行展开操作，以便进行更深入的数据分析和处理。

-```
-
-#### 功能描述
-
-`INLINE` 函数用于将数组中的结构体元素展开成多行数据。输入参数 `expr` 为 `array<struct<T1, T2, ... Tn>>` 类型,展开后的每一列对应结构体元素中的一个字段。如果未指定列名,展开后的列名将与结构体字段名相同。`INLINE` 函数可以直接使用,也可以与 `LATERAL VIEW` 搭配使用以实现更复杂的数据处理。
-
-#### 参数说明
-
-* `expr` : 输入的数组表达式,类型为 `array<struct<T1, T2, ... Tn>>`
-
-#### 返回结果
-
-* 返回类型：根据输入参数 `expr` 进行类型推导,得到 `(T1, T2, ... Tn)` 类型的数据。
-
-#### 使用示例
-
-示例 1：简单的 INLINE 展开
-
-```sql
-SELECT INLINE(array(struct(1, 'x'), struct(2, 'y')));
-+------+------+
-| col1 | col2 |
-+------+------+
-| 1    | x    |
-| 2    | y    |
-+------+------+
-```
-
-示例 2：与 LATERAL VIEW 搭配使用
-
-```sql
-SELECT word, s1, s2 FROM VALUES ('hello') AS vt(word) LATERAL VIEW INLINE(array(struct('a', 0), struct('b', 1))) lv AS s1, s2;
-+-------+----+----+
-| word  | s1 | s2 |
-+-------+----+----+
-| hello | a  | 0  |
-| hello | b  | 1  |
-+-------+----+----+
-```

-### JSON_TUPLE 函数
-
-#### 功能描述
-
-`JSON_TUPLE` 函数用于解析 `JSON` 字符串中的键值对,并将指定的键对应的值提取出来。该函数接受一个 `JSON` 字符串作为输入，并根据提供的键列表（`c1`、`c2`、...、`cN`）提取相应的值。如果 `JSON` 字符串解析失败，函数将返回全列为 `NULL` 的结果；如果某个键不存在于 `JSON` 对象中，对应的列将被填充为 `NULL`。需要注意的是，`JSON_TUPLE` 函数只能解析 `JSON` 对象的顶层键。
-
-该函数可以直接使用，或者与 `LATERAL VIEW` 子句结合使用，以便在更复杂的查询中提取 `JSON` 数据。
-
-#### 参数说明
-
-* `str` (string): 需要解析的 `JSON` 字符串，该字符串应为一个 `JSON` 对象。
-* `c1`, `c2`, ... `cN` (string): 需要提取的 `JSON` 对象中的键。
-
-#### 返回类型
-
-* 返回一个包含提取值的字符串数组，数量与提供的键列表长度相同。
-
-#### 使用示例
-
-**示例 1：基本用法**
-
-```sql
-SELECT json_tuple('{"x" : "1", "y" : 2}', 'x', 'z');
-+------+------+
-| col0 | col1 |
-+------+------+
-| 1    |      |
-+------+------+
-```
-
-上述查询尝试提取键 `x` 和 `z` 的值。由于 `z` 键不存在，返回结果中 `z` 对应的值为空。
-
-**示例 2：与 LATERAL VIEW 结合使用**
-
-```sql
-SELECT a, b, c FROM VALUES ('{"a" : 1.0, "b" : 2}') AS t(word) LATERAL VIEW json_tuple(word, 'a', 'b', 'c') lv AS a, b, c;
-+-----+---+---+
-|  a  | b | c |
-+-----+---+---+
-| 1.0 | 2 |   |
-+-----+---+---+
-```
-
-在这个例子中，我们首先创建了一个包含 `JSON` 字符串的表，然后使用 `LATERAL VIEW` 和 `json_tuple` 函数提取 `a`、`b` 和 `c` 键的值。由于 `c` 键不存在，其对应的值为空。

-TABLE_CHANGES(table_str, start_timestamp, end_timestamp)
-```
-
-**参数要求**：
-
-* `table_str`：已存在的表、动态表或物化视图名称，需提供字符串格式。支持 'schema.tbname'、'tbname' 格式字符串。若未指定 schema，则默认使用当前 schema，即 `current_schema`。
-* `start_timestamp`：查询的时间版本起始时间，需提供标准时间戳类型表达式。
-* `end_timestamp`：查询的时间版本结束时间，需提供标准时间戳类型表达式。
-* opitons:可选参数，目前支持map('TABLE\_STREAM\_MODE', 'ORIGINAL')。当添加此参数时表示获取表变化的原始记录，未添加此参数时比如在start\_timestamp、end\_timestamp之间先insert一条记录再delete这条记录，不添加此参数将会查询不到，如果添加ORIGINAL参数则会显示insert记录和delete记录
-
-**说明**：
-
-* 指定的 `start_timestamp` 不能早于表创建时间，也不能超出数据保留周期。
-* `start_timestamp` 和 `end_timestamp` 分别表示查询的起始和结束时间。查询结果不包括 `start_timestamp` 那一刻的数据，但包括 `end_timestamp` 那一刻的数据。查询时间区间为 (start\_timestamp, end\_timestamp]，左边为开区间，右边为闭区间。

-
-## 功能
-`UNNEST` 是一种用于展开数组或嵌套数据结构的函数,常用于将数组类型的列转换为多行数据,以便进行行级分析。
-
-## **语法**
-```sql
-SELECT [列名] FROM UNNEST(数组表达式) [AS 别名(列名)];
-SELECT [列名] FROM 表名, UNNEST(数组列) [AS 别名(列名)]; -- 隐式 JOIN
-```
-## **参数说明**
-`数组表达式`  ：需要展开的数组或嵌套数据结构（如多维数组、结构体）。
- `别名(列名)`：可选,为展开后的列指定别名和列名。
-`LEFT JOIN` ：可选,保留左表的所有行,即使右表（`UNNEST` 结果）无匹配数据。
-## **使用示例**
-1. **基本数组展开**
-将一维数组展开为多行,每行对应数组中的一个元素。
-**示例：**
-```sql
--- 输入：array(1,2,3)
-SELECT * FROM UNNEST(array(1,2,3));
--- 输出：
--- 1
--- 2
--- 3
-```
- 2. **多数组列展开**
-支持同时展开多个数组,按行对齐。若数组长度不一致,缺失值以 `NULL` 填充。
-**示例：**
-```sql
--- 输入：array(1,2,3), array('ab','cd')
-SELECT * FROM UNNEST(array(1,2,3), array('ab','cd'));
--- 输出：
--- 1    ab
--- 2    cd
--- 3    NULL
-```
-3. **嵌套数组展开**
-支持展开多维数组（递归展开）,生成扁平化结果。
-**示例：**
-```sql
--- 输入：array(array(1,2,3), array(4,5,6))
-SELECT * FROM UNNEST(array(array(1,2,3), array(4,5,6)));
--- 输出：
--- 1
--- 2
--- 3
--- 4
--- 5
--- 6
-```
-
-4. **与 JOIN 结合使用**
-可与其他表通过 `JOIN` 或 `CROSS JOIN` 进行关联,展开数组列。
-**示例：**
-```sql
--- 输入：表 t 包含列 k 和数组列 a
-WITH t AS (SELECT * FROM VALUES (1, array(1,2,3)), (2, array(4,5)) AS t(k, a))
-SELECT * FROM t, UNNEST(a);
--- 输出：
--- 1    [1,2,3]    1
--- 1    [1,2,3]    2
--- 1    [1,2,3]    3
--- 2    [4,5]      4
--- 2    [4,5]      5
-```
-
- 5. **处理 NULL 和空数组**
-- 若数组为 `NULL`,展开后无结果。
-- 若数组为空（`[]`）,展开后同样无结果。
-**示例：**
-```sql
--- 输入：数组列包含 NULL 或空值
-CREATE VIEW student_score AS
-SELECT id, scores FROM VALUES
-(1, [80,85,87]),
-(2, [77, NULL, 89]),
-(3, NULL),
-(4, []) AS students(id, scores);
-
-SELECT id, scores, score FROM student_score, UNNEST(scores) AS t(score);
--- 输出：
--- 1    [80,85,87]    80
--- 1    [80,85,87]    85
--- 1    [80,85,87]    87
--- 2    [77,null,89]  77
--- 2    [77,null,89]  NULL
--- 2    [77,null,89]  89
-```
-6. **过滤展开结果**
-```sql
--- 仅保留偶数元素
-WITH t AS (SELECT * FROM VALUES (1, array(1,2,3)), (2, array(4,5)) AS t(k, a))
-SELECT * FROM t LEFT JOIN UNNEST(a) u(e) WHERE u.e % 2 = 0;
--- 输出：
--- 1    [1,2,3]    2
--- 2    [4,5]      4
-```
-
-
-## **注意事项**
-1. **参数类型限制**
-   `UNNEST` 仅接受数组或嵌套结构作为输入,传递非数组类型会报错。
-   ```sql
-   -- 错误示例：输入为整数
-   SELECT * FROM UNNEST(1); -- 报错：expect array type
-   ```

-### AVG 函数
-
-#### 概述
-
-`AVG` 函数用于计算窗口内表达式的平均值。该函数可以应用于各种数值类型的数据，包括 `TINYINT`、`SMALLINT`、`INT`、`BIGINT`、`FLOAT`、`DOUBLE` 和 `DECIMAL`。返回结果的类型会根据输入类型进行相应的转换，`DECIMAL` 类型的结果会保留原有的精度和标度，其他类型则返回为 `DOUBLE` 类型。需要注意的是，`NULL` 值不会参与平均值的计算。
-
-#### 语法
-
-```sql
-AVG(expr) OVER ([PARTITION_clause] [ORDER_BY_clause] [FRAME_clause])
-```
-
-#### 参数说明
-
-* `expr`: 需要计算平均值的数值类型表达式。
-* `PARTITION_clause`: 可选参数，用于将数据分区，以便在每个分区内分别计算平均值。
-* `ORDER_BY_clause`: 可选参数，用于指定窗口内记录的排序方式。
-* `FRAME_clause`: 可选参数，用于定义窗口的具体范围。
-
-#### 返回结果
-
-`AVG` 函数返回一个数值，表示窗口内数据的平均值。对于 `DECIMAL` 类型，返回结果也是 `DECIMAL` 类型，其精度和标度可能会增加。其他类型的返回结果为 `DOUBLE` 类型。
-
-#### 示例
-
-1. 查询同一个部门（`dep_no`）的工资（`salary`）的平均值，按照部门开窗，不排序：
-
-```sql
-SELECT dep_no, salary, AVG(salary) OVER (PARTITION BY dep_no)
-FROM VALUES
-  ('Eric', 1, 28000),
-  ('Alex', 1, 32000),
-  ('Felix', 2, 21000),
-  ('Frank', 1, 30000),
-  ('Tom', 2, 23000),
-  ('Jane', 3, 29000),
-  ('Jeff', 3, 35000),
-  ('Paul', 2, 29000),
-  ('Charles', 2, 23000)
-AS tab(name, dep_no, salary);
-+--------+--------+------------------------------------------+
-| dep_no | salary | `AVG`(salary) OVER (PARTITION BY dep_no) |

-+--------+--------+------------------------------------------+
-```
-
-2. 查询同一个部门（`dep_no`）的工资（`salary`）的累计平均值，按照部门开窗，按照工资排序。返回当前窗口中从开始行到与当前行工资相同所有行的平均值：
-
-```sql
-SELECT dep_no, salary, AVG(salary) OVER (PARTITION BY dep_no ORDER BY salary)
-FROM VALUES
-  ('Eric', 1, 28000),
-  ('Alex', 1, 32000),

-### COUNT 函数
-
-#### 概述
-
-COUNT 函数用于计算窗口内的数据行数。该函数有两种形式：`count(*)` 和 `count(expr1[,expr2...])`。`count(*)` 计算窗口内所有行的数量，包括包含 NULL 值的行；`count(expr1[,expr2...])` 计算窗口内非 NULL 表达式的数量。
-
-#### 语法
-
-```sql
-count(*) over ([partition_clause] [orderby_clause] [frame_clause])
-count(expr1[,expr2...]) over ([partition_clause] [orderby_clause] [frame_clause])
-```
-
-#### 参数
-
-* `exprN`: 任意类型，用于计算非 NULL 值的数量。
-
-#### 返回结果
-
-* 返回值类型为 bigint 类型。
-* 使用 `count(*)` 时，NULL 值也被计算为一行。
-* 使用 `count(expr1[,expr2...])` 时，任意一列出现 NULL 值，该行将被忽略。
-
-#### 示例 1：计算每个部门的人数
-
-```sql
-SELECT dep_no,name, count(*) OVER (PARTITION BY dep_no)
-FROM VALUES

-### CUME\_DIST 函数
-
-```sql
-cume_dist() OVER ([PARTITION BY column1, column2, ...] [ORDER BY column1 [ASC|DESC], column2 [ASC|DESC], ...])
-```
-
-#### 功能描述
-
-CUME\_DIST 函数用于计算当前行在指定分区中的累计分布比例。具体来说，它返回一个 double 类型的值，表示在当前行及其之前的所有行（在分区内）占整个分区行数的比例。该函数通常用于数据分析，以便了解数据在不同分组中的分布情况。
-
-#### 使用说明
-
-* PARTITION BY 子句用于将数据分为不同的分区。如果未指定 PARTITION BY 子句，则整个数据集将被视为一个分区。
-* ORDER BY 子句用于指定在每个分区内如何对数据进行排序。CUME\_DIST 函数的结果依赖于 ORDER BY 子句的排序顺序。
-* 如果 ORDER BY 列中存在相同的值，CUME\_DIST 函数将为这些行返回相同的结果，即最后一行的 row\_number() 除以窗口行数。
-
-#### 返回结果
-
-* 返回值类型为 double 类型。
-* 结果等于 `last_peer_row_number / partition_row_count`，其中 last\_peer\_row\_number 表示当前行及其之前的所有行（在分区内）的最大 row\_number() 值，partition\_row\_count 表示分区内的总行数。
-
-#### 示例
-
-```sql
-SELECT a,
-       b,
-       ROW_NUMBER() OVER(PARTITION BY a ORDER BY b) AS row_num,
-       CUME_DIST() OVER (PARTITION BY a ORDER BY b) AS cume_dist
-FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
-```
-
-结果：
-
-```
-A	b	row_num	cume_dist
-------------------------------------------------------------------------------------------
-A	1	1	0.6666666666666666
-A	1	2	0.6666666666666666
-A	2	3	1.0
-B	3	1	1.0
-```
-
-在这个示例中，我们可以看到：
-
-* 当 a = 'A' 时，有两个行（b = 1 和 b = 2），它们的 cume\_dist 分别为 0.67（2/3）和 1（3/3）。
-* 当 a = 'B' 时，只有一个行（b = 3），它的 cume\_dist 为 1（1/1）。

-### DENSE\_RANK 函数
-
-#### 概述
-
-`DENSE_RANK` 函数是一个窗口函数，用于计算当前行在指定分区中的连续排名，排名从1开始。当 `ORDER BY` 子句中的值相同时，`DENSE_RANK` 函数会生成相同的排名，但排名的数字不会跳跃。
-
-#### 语法
-
-```sql
-DENSE_RANK() OVER ([PARTITION_clause] [ORDER_BY_clause])
-```
-
-#### 参数说明
-
-* `PARTITION_clause` (可选)：指定分区的子句，用于将数据集划分为不同的分区。如果未指定分区，则对整个数据集应用排名。
-* `ORDER_BY_clause`：指定用于对数据进行排序的列或表达式。
-
-#### 返回类型
-
-返回值类型为 `bigint` 类型。
-
-#### 使用示例
-
-1. 基本使用
-
-```sql
-
-SELECT 
-       name,
-       salary,
-       dense_rank() OVER (PARTITION BY dep_no ORDER BY salary DESC) AS salary_rank
-FROM VALUES
-  ('Eric', 1, 28000),
-  ('Alex', 1, 32000),
-  ('Felix', 2, 21000),
-  ('Frank', 1, 30000),
-  ('Tom', 2, 23000),
-  ('Jane', 3, 29000),
-  ('Jeff', 3, 35000),
-  ('Paul', 2, 29000),
-  ('Charles', 2, 23000),
-  ('Charles F', 2, 23000),
-  ('null',4,null)
-AS tab(name, dep_no, salary);
-+-----------+--------+-------------+
-|   name    | salary | salary_rank |
-+-----------+--------+-------------+
-| Jeff      | 35000  | 1           |
-| Jane      | 29000  | 2           |
-| Alex      | 32000  | 1           |
-| Frank     | 30000  | 2           |
-| Eric      | 28000  | 3           |
-| Paul      | 29000  | 1           |
-| Tom       | 23000  | 2           |
-| Charles   | 23000  | 2           |
-| Charles F | 23000  | 2           |
-| Felix     | 21000  | 3           |
-| null      | null   | 1           |
-+-----------+--------+-------------+
-```
-
-在此示例中，我们根据部门ID对员工进行分区，并按工资降序排列，计算每个员工在其所在部门中的薪资排名。
-
-2. 无分区排名
-
-```sql
-SELECT 
-       name,
-       salary,
-       dense_rank() OVER ( ORDER BY salary DESC) AS salary_rank
-FROM VALUES
-  ('Eric', 1, 28000),
-  ('Alex', 1, 32000),
-  ('Felix', 2, 21000),
-  ('Frank', 1, 30000),
-  ('Tom', 2, 23000),
-  ('Jane', 3, 29000),
-  ('Jeff', 3, 35000),
-  ('Paul', 2, 29000),
-  ('Charles', 2, 23000),
-  ('null',4,null)
-AS tab(name, dep_no, salary);
-+---------+--------+-------------+
-|  name   | salary | salary_rank |
-+---------+--------+-------------+
-| Jeff    | 35000  | 1           |
-| Alex    | 32000  | 2           |
-| Frank   | 30000  | 3           |
-| Jane    | 29000  | 4           |
-| Paul    | 29000  | 4           |
-| Eric    | 28000  | 5           |
-| Tom     | 23000  | 6           |
-| Charles | 23000  | 6           |
-| Felix   | 21000  | 7           |
-| null    | null   | 8           |
-+---------+--------+-------------+
-```
-
-在这个例子中，我们没有指定分区，因此将计算整个产品数据集中的库存排名，按库存数量升序排列。
-
-3. 多列排序
-
-```sql
-SELECT student_id,
-       student_name,
-       exam_score,
-       dense_rank() OVER (PARTITION BY exam_subject ORDER BY exam_score DESC, student_name ASC) AS score_rank
-FROM exam_results;
-```
-
-在这个示例中，我们首先按考试科目进行分区，然后按考试成绩降序排列，如果成绩相同，则按学生姓名升序排列，计算每个学生在各科目考试中的排名。
-
-#### 注意事项
-
-* 当 `ORDER BY` 子句中的值相同时，`DENSE_RANK` 函数不会生成跳跃的排名，排名将重复。
-* 与 `RANK()` 函数相比，`DENSE_RANK()` 函数在处理相同值时具有更紧凑的排名，而 `RANK()` 函数会产生有间断的排名。
-* 在使用 `DENSE_RANK()` 函数时，请确保 `ORDER BY` 子句正确地反映了您希望对数据进行排序的方式。

-### FIRST\_VALUE 函数
-
-#### 概述
-
-排序键相同时，FIRST\_VALUE 函数用于从窗口内返回第一行的值。该函数可以对数据进行分组和排序，以便在特定的数据范围内查找所需的值。通过使用可选的 ignoreNull 参数，可以指定函数在计算时是否忽略 NULL 值。该函数为非确定性函数
-
-#### 语法
-
-```sql
-FIRST_VALUE(expr[, ignoreNull]) OVER ([PARTITION BY partition_clause] [ORDER BY order_by_clause] [frame_clause])
-```
-
-#### 参数
-
-* expr：任意类型的表达式。
-* ignoreNull（可选）：布尔类型常量，默认值为 false。当设置为 true 时，函数将返回窗口内第一个非 NULL 的值。
-
-#### 返回结果
-
-返回值的类型与 expr 参数的类型相同。
-
-#### 示例
-
-1. 基本使用：
-
-```sql
-SELECT dep_no, salary, FIRST_VALUE(salary) OVER (PARTITION BY dep_no) AS first_salary
-FROM VALUES
-  ('Eric', 1, 28000),
-  ('Alex', 1, 32000),
-  ('Felix', 2, 21000),
-  ('Frank', 1, 30000),
-  ('Tom', 2, 23000),
-  ('Jane', 3, 29000),
-  ('Jeff', 3, 35000),
-  ('Paul', 2, 29000),
-  ('Charles', 2, 23000),
-  ('Charles F', 2, 23000),
-  ('null',4,null),
-  ('NotNull',4,23000)
-  AS tab(name, dep_no, salary);
-+--------+--------+-----------------------+
-| dep_no | salary | first_non_null_salary |

-| 2      | 23000  | 21000                 |
-| 2      | 29000  | 21000                 |
-| 2      | 23000  | 21000                 |
-| 2      | 23000  | 21000                 |
-| 4      | null   | null                  |
-| 4      | 23000  | null                  |
-+--------+--------+-----------------------+
-```
-
-2. 忽略 NULL 值：
-
-```sql
-SELECT dep_no, salary, FIRST_VALUE(salary, true) OVER (PARTITION BY dep_no) AS first_non_null_salary
-FROM VALUES
-  ('Eric', 1, 28000),
-  ('Alex', 1, 32000),
-  ('Felix', 2, 21000),
-  ('Frank', 1, 30000),
-  ('Tom', 2, 23000),
-  ('Jane', 3, 29000),
-  ('Jeff', 3, 35000),
-  ('Paul', 2, 29000),
-  ('Charles', 2, 23000),
-  ('Charles F', 2, 23000),
-  ('null',4,null),
-  ('NotNull',4,23000)
-  AS tab(name, dep_no, salary);
-+--------+--------+-----------------------+
-| dep_no | salary | first_non_null_salary |
-+--------+--------+-----------------------+
-| 3      | 29000  | 29000                 |
-| 3      | 35000  | 29000                 |
-| 1      | 28000  | 28000                 |
-| 1      | 32000  | 28000                 |
-| 1      | 30000  | 28000                 |
-| 2      | 21000  | 21000                 |
-| 2      | 23000  | 21000                 |
-| 2      | 29000  | 21000                 |
-| 2      | 23000  | 21000                 |
-| 2      | 23000  | 21000                 |
-| 4      | null   | 23000                 |
-| 4      | 23000  | 23000                 |
-+--------+--------+-----------------------+
-```
-
-3. 结合 ORDER BY 子句：
-
-```sql
-
-SELECT dep_no, salary, FIRST_VALUE(salary, true) OVER (PARTITION BY dep_no ORDER BY salary) AS first_salary_by_salary
-FROM VALUES
-  ('Eric', 1, 28000),
-  ('Alex', 1, 32000),
-  ('Felix', 2, 21000),
-  ('Frank', 1, 30000),

-  ('Paul', 2, 29000),
-  ('Charles', 2, 23000),
-  ('Charles F', 2, 23000),
-  ('null',4,null),
-  ('NotNull',4,23000)
-  AS tab(name, dep_no, salary);
-+--------+--------+------------------------+
-| dep_no | salary | first_salary_by_salary |

-### LAG 函数
-
-#### 简介
-
-LAG 函数用于获取当前行的前一行或指定行数的行数据。通过使用 LAG 函数，您可以轻松地访问窗口内的前一行数据，以便进行计算或比较。
-
-#### 语法
-
-```sql
-LAG(expr[,offset[,default]]) OVER ([partition_clause] orderby_clause)
-```
-
-#### 参数说明
-
-* `expr` (任意类型): 需要获取前一行的表达式。
-* `offset` (可选，`bigint` 类型常量，默认为 1): 表示从当前行向前移动的行数。当值为 0 时，表示当前行；当值为正数时，表示向前移动的行数；当值为负数时，表示向后移动的行数。
-* `default` (可选，与 `expr` 类型相同的常量，默认为 `null`): 当 `offset` 超出窗口边界时使用的默认值。
-
-#### 返回结果
-
-返回与 `expr` 相同的数据类型。
-
-#### 使用示例
-
-1. 获取前一行的数据：
-
-```sql
-SELECT a, b, LAG(b) OVER (PARTITION BY a ORDER BY b) as prev_b FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
-```
-
-结果：
-
-```
-A	1	null
-A	1	1
-A	2	1
-B	3	null
-```
-
-2. 获取前两行的数据：
-
-```sql
-SELECT a, b, LAG(b, 2) OVER (PARTITION BY a ORDER BY b) as prev_b FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
-```
-
-结果：
-
-```
-A	1	null
-A	2	null
-A      2        1
-B	3	null
-```
-
-3. 使用默认值：
-
-```sql
-SELECT a, b, LAG(b, 1, 0) OVER (PARTITION BY a ORDER BY b) as prev_b FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
-```
-
-结果：
-
-```
-A	1	0
-A	1	1
-A	2	1
-B	3	0
-```
-
-#### 总结
-
-LAG 函数是一个非常实用的工具，可以帮助您轻松地访问窗口内的前一行数据。通过调整 offset 和 default 参数，您可以灵活地获取所需的数据。在实际应用中，LAG 函数可以用于计算移动平均、累积和等统计指标。

-
-#### 参数说明
-
-* `expr`：任意类型的表达式，表示要获取的值。
-* `ignoreNull`（可选）：布尔值，表示是否忽略 NULL 值。默认为 false，即不忽略 NULL 值。当参数值为 true 时，LAST 函数将返回窗口内最后一条非 NULL 的值。
-
-#### 返回结果
-
-返回值类型与 expr 参数类型相同。
-
-#### 使用示例
-
-1. 基本使用：
-
-   ```sql
-
-   SELECT name, salary, LAST(salary) OVER (PARTITION BY salary ) as min_salary
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),

-   | Alex      | 32000  | 32000      |
-   +-----------+--------+------------+
-   ```
-
-2. 忽略 NULL 值：
-
-   在这个例子中，我们将忽略工资为 NULL 的记录。
-
-   ```sql
-   SELECT name, salary, LAST(salary,true) OVER (PARTITION BY salary ) as min_salary
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+------------+
-   |   name    | salary | min_salary |
-   +-----------+--------+------------+
-   | null      | null   | null       |
-   | Eric      | 28000  | 28000      |
-   | Jeff      | 35000  | 35000      |
-   | Frank     | 30000  | 30000      |
-   | Felix     | 21000  | 21000      |
-   | Tom       | 23000  | 23000      |
-   | Charles   | 23000  | 23000      |
-   | Charles F | 23000  | 23000      |
-   | NotNull   | 23000  | 23000      |
-   | Jane      | 29000  | 29000      |
-   | Paul      | 29000  | 29000      |
-   | Alex      | 32000  | 32000      |
-   +-----------+--------+------------+
-   ```
-
-3. 结合 ORDER BY 使用：
-
-   ```sql
-   SELECT name, salary, LAST(salary) OVER (PARTITION BY dep_no ORDER BY dep_no DESC) as min_salary
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+------------+
-   |   name    | salary | min_salary |
-   +-----------+--------+------------+
-   | Jane      | 29000  | 35000      |
-   | Jeff      | 35000  | 35000      |
-   | Eric      | 28000  | 30000      |
-   | Alex      | 32000  | 30000      |
-   | Frank     | 30000  | 30000      |
-   | Felix     | 21000  | 23000      |
-   | Tom       | 23000  | 23000      |
-   | Paul      | 29000  | 23000      |
-   | Charles   | 23000  | 23000      |
-   | Charles F | 23000  | 23000      |
-   | null      | null   | 23000      |
-   | NotNull   | 23000  | 23000      |
-   +-----------+--------+------------+
-   ```
-
-4. 使用窗口函数：
-
-   当您需要对整个数据集应用 LAST 函数时，可以使用 `ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING` 子句。
-
-   ```sql
-   SELECT name, salary, LAST(salary, true) OVER (ORDER BY salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) as global_min_salary
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+-------------------+
-   |   name    | salary | global_min_salary |
-   +-----------+--------+-------------------+
-   | null      | null   | 35000             |
-   | Felix     | 21000  | 35000             |
-   | Tom       | 23000  | 35000             |
-   | Charles   | 23000  | 35000             |
-   | Charles F | 23000  | 35000             |
-   | NotNull   | 23000  | 35000             |
-   | Eric      | 28000  | 35000             |
-   | Jane      | 29000  | 35000             |
-   | Paul      | 29000  | 35000             |

-   | Jeff      | 35000  | 35000             |
-   +-----------+--------+-------------------+
-   ```

-   | Alex      | 32000  | 32000      |
-   +-----------+--------+------------+
-   ```
-
-2. 忽略 NULL 值：
-
-   在这个例子中，我们将忽略工资为 NULL 的员工。
-
-   ```sql
-   SELECT name, salary, LAST_VALUE(salary,true) OVER (PARTITION BY salary ) as min_salary
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+------------+
-   |   name    | salary | min_salary |
-   +-----------+--------+------------+
-   | null      | null   | null       |
-   | Eric      | 28000  | 28000      |
-   | Jeff      | 35000  | 35000      |
-   | Frank     | 30000  | 30000      |
-   | Felix     | 21000  | 21000      |
-   | Tom       | 23000  | 23000      |
-   | Charles   | 23000  | 23000      |
-   | Charles F | 23000  | 23000      |
-   | NotNull   | 23000  | 23000      |
-   | Jane      | 29000  | 29000      |
-   | Paul      | 29000  | 29000      |
-   | Alex      | 32000  | 32000      |
-   +-----------+--------+------------+
-   ```
-
-3. 结合 ORDER BY 使用：
-
-   ```sql
-   SELECT name, salary, LAST_VALUE(salary) OVER (PARTITION BY dep_no ORDER BY dep_no DESC) as min_salary
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+------------+
-   |   name    | salary | min_salary |
-   +-----------+--------+------------+
-   | Jane      | 29000  | 35000      |
-   | Jeff      | 35000  | 35000      |
-   | Eric      | 28000  | 30000      |
-   | Alex      | 32000  | 30000      |
-   | Frank     | 30000  | 30000      |
-   | Felix     | 21000  | 23000      |
-   | Tom       | 23000  | 23000      |
-   | Paul      | 29000  | 23000      |
-   | Charles   | 23000  | 23000      |
-   | Charles F | 23000  | 23000      |
-   | null      | null   | 23000      |
-   | NotNull   | 23000  | 23000      |
-   +-----------+--------+------------+
-   ```
-
-4. 使用窗口函数：
-
-   当您需要对整个数据集应用 LAST 函数时，可以使用 ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING 子句。
-
-   ```sql
-   SELECT name, salary, LAST_VALUE(salary, true) OVER (ORDER BY salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) as global_min_salary
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+-------------------+
-   |   name    | salary | global_min_salary |
-   +-----------+--------+-------------------+
-   | null      | null   | 35000             |
-   | Felix     | 21000  | 35000             |
-   | Tom       | 23000  | 35000             |
-   | Charles   | 23000  | 35000             |
-   | Charles F | 23000  | 35000             |
-   | NotNull   | 23000  | 35000             |
-   | Eric      | 28000  | 35000             |
-   | Jane      | 29000  | 35000             |
-   | Paul      | 29000  | 35000             |

-### LEAD 函数
-
-#### 简介
-LEAD 函数是窗口函数的一种，用于访问当前行之后指定偏移量的行。通过使用 LEAD 函数，您可以获取当前行向分区尾部方向移动指定行数后对应的表达式的值。这在数据分析和处理中非常有用，例如比较当前行与下一行的数据差异。
-
-#### 语法
-```sql
-LEAD(expr[, offset[, default]]) OVER ([PARTITION BY clause] ORDER BY clause)
-```
-
-#### 参数
-- `expr`: 任意类型的表达式，可以是列名、常量或函数等。
-- `offset`: 可选参数，bigint 类型常量，默认值为 1，表示当前行后面的一行。当 offset 为 0 时，表示当前行本身。
-- `default`: 可选参数，当 offset 超过窗口的边界时使用的缺省值。类型与 expr 相同，默认值为 null。
-
-#### 返回结果
-返回值类型与 expr 相同。
-
-#### 使用示例
-
-1. 基本使用
-```sql
-SELECT a, b, LEAD(b) OVER (PARTITION BY a ORDER BY b) as next_b FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
-```
-结果：
-```
-A	1	1
-A	1	2
-A	2	null
-B	3	null
-```
-
-2. 使用 offset 和 default 参数
-```sql
-SELECT a, b, LEAD(b, 2, 0) OVER (PARTITION BY a ORDER BY b) as next_b FROM VALUES ('A', 2), ('A', 1), ('B', 3), ('A', 1) tab(a, b);
-```
-结果：
-```
-A	1	2
-A	1	0
-A	2	0
-B	3	0
-```
-
-
-#### 注意事项
-- 当 offset 值超出窗口边界时（例如，当前行之后没有足够的行），LEAD 函数将返回 default 参数指定的值。
-- LEAD 函数通常与窗口函数的 ORDER BY 子句一起使用，以确定如何访问相关行。
-- 在使用 LEAD 函数时，请确保正确设置 PARTITION BY 子句，以便正确地对数据进行分区。

-# NTH\_VALUE 函数
-
-## 简介
-
-NTH\_VALUE 函数用于从指定窗口内返回第 offset 行的值。该函数在处理数据时非常有用，特别是当需要获取特定位置的数据时。
-
-## 语法
-
-```sql
-nth_value(expr, offset[,ignoreNull]) over ([partition_clause] [orderby_clause] [frame_clause])
-```
-
-## 参数
-
-* `expr`: 任意类型的表达式。
-* `offset`: 大整数类型（BIGINT），必须是正整数常量。当 offset 为 1 时，函数行为与 FIRST\_VALUE 函数相同。
-* `ignoreNull`: 可选参数，布尔类型常量，默认为 false。当设置为 true 时，函数将返回窗口内第 offset 个非 null 的值。
-
-## 返回结果
-
-返回值类型与 expr 类型相同。
-
-## 使用示例
-
-```sql
-SELECT dep_no, salary, nth_value(salary, 3) OVER (PARTITION BY dep_no)
-FROM VALUES
-  ('Eric', 1, null),
-  ('Alex', 1, 32000),
-  ('Felix', 2, 21000),
-  ('Frank', 1, 30000),
-  ('Tom', 2, 23000),

-### 百分比排名函数（PERCENT\_RANK）
-
-#### 概述
-
-`PERCENT_RANK` 函数用于计算指定行在其所在分区中的百分比排名。该函数会根据 `ORDER BY` 子句指定的排序顺序对数据进行排序，并计算每个分区中各行的排名。其返回值是一个 `double` 类型，值域在 [0.0, 1.0] 范围内。具体计算公式为 `(当前行排名 - 1) / (分区总行数 - 1)`。当分区中只有一行时，返回值为 0。
-
-#### 使用方法
-
-```sql
-PERCENT_RANK() OVER (
-    [PARTITION BY partition_expression, ...]
-    [ORDER BY sort_expression [ASC | DESC], ...]
-)
-```
-
-* `PARTITION BY` 子句（可选）：指定用于分区的表达式，可以有多个。如果省略此子句，将使用整个结果集作为一个分区。
-* `ORDER BY` 子句：指定用于排序的表达式，可以有多个，并可指定排序方向（升序 ASC 或降序 DESC）。
-
-#### 示例
-
-以下示例展示了如何使用 `PERCENT_RANK` 函数计算不同部门人员的薪水排名百分比。
-
-```sql
-SELECT    name, dep_no,salary,
-PERCENT_RANK() OVER (PARTITION BY dep_no ORDER BY  salary DESC) AS PERCENT_RANK
- FROM VALUES

-### RANK 函数
-
-#### 概述
-
-`RANK()` 函数用于计算当前行在指定分区中的排名。排名从 1 开始，根据 `ORDER BY` 子句中的值进行排序。若存在相同的排序值，`RANK()` 函数会将相同的排名分配给这些行，并将下一个排名跳过。
-
-#### 语法
-
-```sql
-RANK() OVER ([PARTITION BY column_name | column_name, ...] [ORDER BY column_name [ASC|DESC], ...])
-```
-
-#### 参数说明
-
-* `PARTITION BY`：可选参数，用于将数据分区。可以指定一个或多个列名，对数据进行分区。
-* `ORDER BY`可选参数，用于指定排序的列和排序方式（升序或降序）。
-
-#### 返回值
-
-* 返回值类型为 bigint 类型。
-* 返回值可能不连续，可能重复。若存在相同的 `ORDER BY` 值，结果相同，为第一个 `ORDER BY` 行的排名。
-
-#### 示例
-
-1. 基本使用
-   我们可以使用 `RANK()` 函数来计算每个员工的薪水排名。
-   ```sql
-   SELECT name, salary, RANK() OVER (ORDER BY salary DESC) AS rank 
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+------+
-   |   name    | salary | rank |
-   +-----------+--------+------+
-   | Jeff      | 35000  | 1    |
-   | Alex      | 32000  | 2    |
-   | Frank     | 30000  | 3    |
-   | Jane      | 29000  | 4    |
-   | Paul      | 29000  | 4    |
-   | Eric      | 28000  | 6    |
-   | Tom       | 23000  | 7    |
-   | Charles   | 23000  | 7    |
-   | Charles F | 23000  | 7    |
-   | NotNull   | 23000  | 7    |
-   | Felix     | 21000  | 11   |
-   | null      | null   | 12   |
-   +-----------+--------+------+
-   ```
-
-2. 分区使用
-   如果我们想要根据员工的部分（grade）来计算薪水排名，可以使用 `PARTITION BY` 子句。
-
-```SQL
- SELECT name,dep_no, salary, RANK() OVER (PARTITION BY dep_no ORDER BY salary DESC) AS rank 
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+--------+------+
-   |   name    | dep_no | salary | rank |
-   +-----------+--------+--------+------+
-   | Jeff      | 3      | 35000  | 1    |
-   | Jane      | 3      | 29000  | 2    |
-   | Alex      | 1      | 32000  | 1    |
-   | Frank     | 1      | 30000  | 2    |
-   | Eric      | 1      | 28000  | 3    |
-   | Paul      | 2      | 29000  | 1    |
-   | Tom       | 2      | 23000  | 2    |
-   | Charles   | 2      | 23000  | 2    |
-   | Charles F | 2      | 23000  | 2    |
-   | Felix     | 2      | 21000  | 5    |
-   | NotNull   | 4      | 23000  | 1    |
-   | null      | 4      | null   | 2    |
-   +-----------+--------+--------+------+
-```
-
-3. 多列排序
-   如果我们需要根据两个或更多列进行排序，可以在 `ORDER BY` 子句中指定这些列。
-   ```sql
-   SELECT name,dep_no, salary, RANK() OVER (PARTITION BY dep_no ORDER BY salary DESC,name ASC) AS rank 
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+--------+------+
-   |   name    | dep_no | salary | rank |
-   +-----------+--------+--------+------+
-   | Jeff      | 3      | 35000  | 1    |
-   | Jane      | 3      | 29000  | 2    |
-   | Alex      | 1      | 32000  | 1    |
-   | Frank     | 1      | 30000  | 2    |
-   | Eric      | 1      | 28000  | 3    |
-   | Paul      | 2      | 29000  | 1    |
-   | Charles   | 2      | 23000  | 2    |
-   | Charles F | 2      | 23000  | 3    |
-   | Tom       | 2      | 23000  | 4    |
-   | Felix     | 2      | 21000  | 5    |
-   | NotNull   | 4      | 23000  | 1    |
-   | null      | 4      | null   | 2    |
-   +-----------+--------+--------+------+
-   ```
-
-#### 注意事项
-
-* `RANK()` 函数可能在存在相同排序值的情况下产生不连续的排名。
-* 使用 `RANK()` 函数时，确保 `ORDER BY` 子句中的列与您希望根据其排名的列相匹配。

-`ROW_NUMBER()` 函数用于计算当前分区中当前行的行号，行号从 1 开始，按指定的 `ORDER BY` 子句进行排序。该函数在处理数据时非常有用，特别是当你需要为结果集中的每一行分配一个唯一的序号时。
-
-#### 语法
-
-```sql
-ROW_NUMBER() OVER (
-  [PARTITION BY partition_expression, ...]
-  ORDER BY sort_expression [ASC | DESC]
-)
-```
-
-#### 参数说明
-
-* `partition_expression`：用于定义分区的表达式，可以有多个，用于将结果集分成多个分区。
-* `sort_expression`：用于指定排序的表达式，可以是列名或者表达式，用于在每个分区内对行进行排序。
-* `ASC` | `DESC`：可选参数，用于指定排序方向，默认为 `ASC`。
-
-#### 返回结果
-
-* 返回值类型为 `bigint` 类型。
-* 返回的行号连续且不重复。
-
-#### 使用示例
-
-1. 基本使用：
-   ```sql
-
-     SELECT name, salary, ROW_NUMBER() OVER (ORDER BY salary DESC) AS row_num 
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+---------+
-   |   name    | salary | row_num |
-   +-----------+--------+---------+
-   | Jeff      | 35000  | 1       |
-   | Alex      | 32000  | 2       |
-   | Frank     | 30000  | 3       |
-   | Jane      | 29000  | 4       |
-   | Paul      | 29000  | 5       |
-   | Eric      | 28000  | 6       |
-   | Tom       | 23000  | 7       |
-   | Charles   | 23000  | 8       |
-   | Charles F | 23000  | 9       |
-   | NotNull   | 23000  | 10      |
-   | Felix     | 21000  | 11      |
-   | null      | null   | 12      |
-   +-----------+--------+---------+
-   ```
-
-2. 使用分区：
-   ```sql
-   SELECT name,dep_no, salary, RANK() OVER (PARTITION BY dep_no ) AS row_num 
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+--------+---------+
-   |   name    | dep_no | salary | row_num |
-   +-----------+--------+--------+---------+
-   | Jane      | 3      | 29000  | 1       |
-   | Jeff      | 3      | 35000  | 1       |
-   | Eric      | 1      | 28000  | 1       |
-   | Alex      | 1      | 32000  | 1       |
-   | Frank     | 1      | 30000  | 1       |
-   | Felix     | 2      | 21000  | 1       |
-   | Tom       | 2      | 23000  | 1       |
-   | Paul      | 2      | 29000  | 1       |
-   | Charles   | 2      | 23000  | 1       |
-   | Charles F | 2      | 23000  | 1       |
-   | null      | 4      | null   | 1       |
-   | NotNull   | 4      | 23000  | 1       |
-   +-----------+--------+--------+---------+
-   ```
-
-3. 多列排序：
-   ```sql
-   SELECT name,dep_no, salary, ROW_NUMBER() OVER (PARTITION BY dep_no ORDER BY salary DESC,name ASC) AS row_num 
-    FROM VALUES
-     ('Eric', 1, 28000),
-     ('Alex', 1, 32000),
-     ('Felix', 2, 21000),
-     ('Frank', 1, 30000),
-     ('Tom', 2, 23000),
-     ('Jane', 3, 29000),
-     ('Jeff', 3, 35000),
-     ('Paul', 2, 29000),
-     ('Charles', 2, 23000),
-     ('Charles F', 2, 23000),
-     ('null',4,null),
-     ('NotNull',4,23000)
-     AS tab(name, dep_no, salary);
-   +-----------+--------+--------+---------+
-   |   name    | dep_no | salary | row_num |
-   +-----------+--------+--------+---------+
-   | Jeff      | 3      | 35000  | 1       |
-   | Jane      | 3      | 29000  | 2       |
-   | Alex      | 1      | 32000  | 1       |
-   | Frank     | 1      | 30000  | 2       |
-   | Eric      | 1      | 28000  | 3       |
-   | Paul      | 2      | 29000  | 1       |
-   | Charles   | 2      | 23000  | 2       |
-   | Charles F | 2      | 23000  | 3       |
-   | Tom       | 2      | 23000  | 4       |
-   | Felix     | 2      | 21000  | 5       |
-   | NotNull   | 4      | 23000  | 1       |
-   | null      | 4      | null   | 2       |
-   +-----------+--------+--------+---------+
-   ```
-
-#### 注意事项
-
-* `ROW_NUMBER()` 函数对于每个分区都是独立的，即每个分区都会有自己的行号序列。
-* 使用 `ROW_NUMBER()` 函数时，应确保 `ORDER BY` 子句中的排序键是唯一的，以避免产生非连续的行号。
-* 当 `ORDER BY` 子句中的排序键存在相同值时，默认情况下 `ROW_NUMBER()` 函数会产生非连续的行号。如果需要连续的行号，可以考虑使用 `DENSE_RANK()` 函数。

-### 窗口函数概述
-
-窗口函数是 SQL 中一种强大的分析工具，它允许您在一组相关行上执行计算，而不仅仅是针对单个行。窗口函数通过创建一个“窗口”来查看当前行及其上下文行，从而实现复杂的数据分析任务。
-
-#### 语法
-
-```sql
-function_name([expr [, ...]]) OVER ( [window_definition] )
-```
-
-* `function_name`: 内置的窗口函数，如 `SUM`、`COUNT` 等。
-* `expr`: 函数参数，根据实际数据确定。
-* `window_definition`: 窗口定义，用于指定如何在数据集上应用窗口函数。
-
-#### 窗口定义
-
-```sql
-[PARTITION BY expression [, ...]]
-[ORDER BY expression [ASC|DESC]] [, ...]
-[FRAME frame_clause]
-```
-
-* `PARTITION BY` 子句: 可选，用于将数据集划分为不同的分区。
-* `ORDER BY` 子句: 可选，用于指定数据在每个窗口内的排序方式。建议使用唯一的列或列组合来减少随机性。
-* `FRAME` 子句: 可选，用于确定窗口的边界。具体描述如下。
-
-#### FRAME 子句
-
-```sql
-{ROWS|RANGE} BETWEEN frame_start AND frame_end
-```
-
-`FRAME` 子句定义了一个闭区间，用于确定数据边界。`ROWS` 和 `RANGE` 是两种类型的边界类型。
-
-* `ROWS` 类型: 通过数据行号确定边界。
-* `RANGE` 类型: 当指定了 `ORDER BY` 时，使用列值的大小关系来确定边界。未指定 `ORDER BY` 时，所有行被认为具有相同的值。
-
-`frame_start` 和 `frame_end` 表示窗口的起始和终止边界。`frame_start` 是必填的，`frame_end` 可选，默认值为 `CURRENT ROW`。具体选项如下：
-
-- `UNBOUNDED PRECEDING`: 表示分区或结果集的开始。
-- `OFFSET PRECEDING`: 表示相对于当前行的偏移量。
-- `CURRENT ROW`: 仅表示当前行。
-- `OFFSET FOLLOWING`: 表示相对于当前行之后的偏移量。
-- `UNBOUNDED FOLLOWING`: 表示分区或结果集的结束。
-
-在没有显式设置 `FRAME` 子句时，默认的 `FRAME` 子句为：
-
-```sql
-RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
-```
-
-#### 使用示例
-
-```sql
-SELECT
-  name,
-  dep_no,
-  salary,
-  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) rows_up_uf,
-  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) range_up_uf,
-  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) rows_up_cr,
-  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) range_up_cr,
-  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary ROWS BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING) rows_cr_uf,
-  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary RANGE BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING) range_cr_uf,
-  COUNT(salary) OVER (PARTITION BY dep_no ORDER BY salary ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING) rows_1p_1f
-FROM VALUES
-  ('Eric', 1, 28000),
-  ('Alex', 1, 32000),
-  ('Felix', 2, 21000),
-  ('Frank', 1, 30000),
-  ('Lily', 2, 23000),
-  ('Jane', 3, 29000),
-  ('Jeff', 3, 35000),
-  ('Paul', 2, 29000),
-  ('Charles', 2, 23000)
-  AS tab(name, dep_no, salary);
-```
-
-#### 窗口函数分类
-
-窗口函数根据其行为可以分为以下三类：
-
-1. 排名函数（ranking_function）：用于计算排名，必须指定 `ORDER BY`，不能指定 `FRAME` 子句。例如：
-   - `ROW_NUMBER`
-   - `RANK`
-   - `DENSE_RANK`
-   - `PERCENT_RANK`
-   - `NTILE`
-2. 分析函数（analytic_function）：用于执行更复杂的分析计算。例如：
-   - `CUME_DIST`
-   - `

-# 使用SQL对客户进行RFM分析
-# # **什么是 RFM 分析？**
-**RFM 报告**是一种使用三个关键指标对客户进行细分的方法：新近度（他们上次购买是在多长时间前）、频率（他们购买的频率）和货币价值（他们花了多少钱）。
-
-**RFM 分析**基于这样的假设，即最近从您那里购买过的客户更有可能再次购买这一原则适用于各种行业，有证据表明，与不经常购买或消费较少的客户相比，频繁购买者和大手笔消费者更有可能对促销活动做出反应。
-
-**RFM**创建于上世纪 90 年代，旨在提高直邮营销活动的效率，它利用[**帕累托原理**](https://mode.com/blog/pareto-chart-101/)来回答关键问题，例如：
-
-* 谁是我最好或最忠诚的客户？
-* 我有失去哪些客户的危险？
-* 我应该将营销工作重点放在哪些客户身上？
-* 我可以吸引哪些客户花更多钱？
-
-**这种客户分析会对您的业务产生巨大影响** 无论您是想提高营销 ROI、建立忠诚度、减少客户流失还是增加CLV，RFM 分析都是朝着正确方向迈出的一步。
-
-一旦您有了包含每个客户的新近度（R）、频率（F）和货币价值（M）数据的表格，就可以开始细分了。虽然您可以根据需要对数据进行精细分割，但使用五分位数反映了帕累托原则，它表明您的哪些客户在所有三个指标中都处于前 20%。
-要创建五分位数，我们将使用一个ntile窗口函数，它只需要在原始RFM 值查询的顶部添加几行额外的 SQL 。
-##  **如何为数据创建 RFM 报告**
-
-因为它只关注三个指标，RFM 报告看似简单。例如，在对 数据 进行 RFM 分析时，您真正需要的只是三个数据点：
-
-* **新近度（R，recency）**- 最后订购日期
-* **频率（F，frequency）**- 订单总数
-* **货币价值（M，monetary）**- 总支出
-
-**这些指标共同揭示了您的回头客是谁，哪些客户随着时间的推移最忠诚，以及哪些客户在您的商店中花费最多**。 RFM 报告提供有关您的客户的重要信息，虽然 RFM 与 B2C 和零售密切相关，但对于 B2B、服务或 SaaS 企业来说，它是更好地了解其客户的同样有效的方式。
-
-## 数据说明
-本文所使用的数据来自云器Lakehouse的共享样例数据，可以直接按照如下方式直接使用:
-```
-select * from clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore limit 10;
-```
-![](.topwrite/assets/image_1718761578596.png)
-
-## 创建RFM需要的值
-```
-DROP TABLE if exists eCommerce_RFM_Values;
-
-CREATE TABLE eCommerce_RFM_Values
-
-AS
-
-SELECT user_id,
-
-MIN(event_date) AS first_order_date,
-
-MAX(event_date) AS last_order_date,
-
-COUNT(1) AS count_order,
-
-sum(price) AS sum_amount
-
-FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore
-
-WHERE event_type = 'purchase'
-
-GROUP BY user_id
-
-ORDER BY user_id;
-```
-## 创建RFM Quintiles
-本文为了简单演示，用了两分位（ntile(2)，而不是ntile(5)）。此查询返回一个表，其中包含客户电子邮件以及每个客户在新近度、频率和货币价值方面所属的二分位数。从新近度来看，2 表示客户的购买在最近的前 50% 内，而 1 表示客户在后 50% 内。
-```
-DROP TABLE if exists eCommerce_RFM_Quintiles;
-
-CREATE TABLE eCommerce_RFM_Quintiles
-
-AS
-
-SELECT user_id,
-
-ntile(2) OVER (ORDER BY last_order_date) AS rfm_recency,
-
-ntile(2) OVER (ORDER BY count_order) AS rfm_frequency,
-
-ntile(2) OVER (ORDER BY sum_amount) AS rfm_monetary,
-
-first_order_date,
-
-last_order_date,
-
-count_order,
-
-sum_amount
-
-FROM eCommerce_RFM_Values
-
-ORDER BY user_id;
-```
-## 创建 RFM 单元
-现在您知道了您的客户通常属于哪里，让我们使五分位数数据更易于使用。最常见的方法是将每个指标的五分位等级连接起来，以创建一个3 位数，也称为“单元格”。
-以这种方式连接数据时，最佳客户的单元格值为 222（五分位则为555），因为他们在所有三个指标中都处于前 50%，而在所有三个指标中处于后 50% 的客户的单元格值为 111 .
-```
-DROP TABLE if exists eCommerce_RFM_Cell;
-CREATE TABLE eCommerce_RFM_Cell
-
-AS
-
-SELECT user_id,
-
-rfm_recency,
-
-rfm_frequency,
-
-rfm_monetary,
-
-rfm_recency || rfm_frequency || rfm_monetary AS rfm_cell,
-
-first_order_date,
-
-last_order_date,
-
-count_order,
-
-sum_amount
-
-FROM eCommerce_RFM_Quintiles
-
-ORDER BY user_id;
-```
-## 创建可操作的 RFM Segment
-
-现在您已经有了清晰的 RFM 单元，您需要创建有意义的分组，以帮助将数据转化为可操作的见解。通过三个指标和每个指标的五个层级，您可以创建多达 125 (5x5x5) 个客户群。如果 125 段的想法让您头疼，请考虑使用四分位数（这会给您 4x4x4 = 64 个段）甚至三分之一（3x3x3 = 27 个段）来简化事情。
-
-如何划分细分市场取决于您的业务性质。如果您是 Pareto 的铁杆粉丝，想要奖励您的最佳购买者，您可能希望关注 RFM 单元格为 555 的客户。但是，如果您想要稍微开放一些，以包括最近和常客，他们可能有花费少一点，您可以创建一个细分，其中包含 RFM 单元格值为 555 和 554 的每个人。
-

-# 概述
-
-Star Schema Benchmark（简称 SSB）是一种用于评估 OLAP 系统性能的基准测试。SSB 基于 TPC-H 提供了一个简化版的星型模型数据集，主要用于测试在星型模型下多表关联查询的性能表现。ClickHouse 官方将 SSB 的星型模型打平转化成宽表，改造成了一个单表测试集，参见 [ClickHouse官方说明](https://clickhouse.com/docs/en/getting-started/example-datasets/star-schema)。
-
-本报告为您提供了云器 Lakehouse 与 ClickHouse 在 SSB 单表测试集 100GB 规模上的测试结果，结论如下：
-
-![](.topwrite/assets/image_1731490816583.png)

-# 单点登录 （Private Preview）
-
-本文档旨在帮助您逐步完成单点登录配置，确保能顺利使用 OAuth 2.0/OIDC 或 SAML 2.0 协议启用 SSO 功能。
-
-***
-
-## 基础概念简介
-
-* **单点登录**（**SSO**）：用户通过一次身份验证即可访问多个系统，简化登录流程并提高安全性。
-
-* **联合身份验证（Federated Authentication）**：Lakehouse（服务提供方，SP）信任外部身份提供方（IdP）执行用户认证。
-
-* **协议简述**：
-
-  * **SAML 2.0**：基于 XML 的身份断言协议，通过 Assertion 传递用户身份信息。
-  * **OAuth 2.0 / OpenID Connect（OIDC）**：OAuth 提供授权机制，OIDC 增加身份层，使用 JWT 格式的 ID Token 表达用户身份。
-
-## ClickZetta 与客户 IdP 的关系
-
-* 在 IdP 中注册 Lakehouse 应用（提供回调地址/ACS、Entity ID、签名或加密证书）
-* 在 Lakehouse 平台中填写 IdP 提供的参数
-* 配置完成后支持两种登录流程：用户从 Lakehouse 登录（SP-init）或从 IdP 登录（如果支持 IdP-init）
-
-## 功能局限
-
-当前 Lakehouse **不支持**以下功能，请在配置与使用时注意：
-
-1. **不支持全局登出**。用户在 IdP 的登出操作不影响在 Lakehouse 的登录状态。用户需要在 Lakehouse 中单独登出。
-2. **不支持配置多个 IdP**。仅支持一个 IdP 连接。
-3. **单点登录仅支持 Web 端登录**。当前不支持通过 JDBC、Python SDK、Java SDK 等使用 SSO 登录。
-4. **身份映射字段局限**：SAML 2.0 协议仅支持使用 Email 作为用户身份映射字段；OAuth 2.0 / OpenID Connect (OIDC) 协议仅支持使用 Email 或 Phone 作为用户身份映射字段。
-5. **身份映射字段唯一性要求**：当某字段被用作身份映射字段时，在 Lakehouse 中所有用户的该字段信息须保持唯一。如果 Lakehouse 中多个用户的邮箱或手机号信息存在重复，且该字段被用于单点登录的身份映射字段，则信息重复的用户将不能正常登录。
-
-***
-
-## 协议配置指南
-
-### 开启单点登录
-
-Lakehouse账户中，SSO登录（单点登录）默认关闭。拥有账户管理员身份的用户可以操作开启。
-
-登录 Lakehouse 账户，进入“账户中心”页面，在 SSO 登录选项中，点击“开启 SSO 登录”。
-
-![](.topwrite/assets/screenshot-20250814-145644.png)
-
-**注意**：开启 SSO 登录后，该账户下所有用户只能使用 SSO 方式登录，不再允许使用用户名/密码方式进行 Web 登录。因此在开启单点登录前，请确保账户下所有需要登录 Lakehouse 的用户：
-
-1）在Idp中拥有用户身份；
-
-2）在Lakehouse中用于身份映射的信息（邮箱或电话号码）唯一，不与其他用户重复。
-
-### OAuth 2.0 / OpenID Connect (OIDC) 协议
-
-**1. 选择协议**
-
-开启 SSO 登录后，在右侧弹窗中选择 “OAuth 2.0 / OIDC 协议”。选择协议后，您可在协议下方看到该协议的回调地址，如：
-
-:-: ![](.topwrite/assets/image_1755158785697.png =575)
-
-```SQL
-https://api.clickzetta.com/clickzetta-portal/sso/oidc/consume?u={code}
-```
-
-^
-
-请使用该回调地址，在您的 IdP 服务中注册 Lakehouse 应用，并记录注册后的 Client ID 和其他配置值，以便在后续配置中使用。
-
-**配置授权端点（Authorization Endpoint）**
-
-:-: ![](.topwrite/assets/image_1755160968700.png =525)
-
-**参数**：
-
-* 授权端点URL（例如 `https://idp.example.com/authorize`）：用于重定向用户到 IdP 进行身份授权
-* Client ID：标识 Lakehouse 在 IdP 上的应用，您可在您的 IdP 服务中完成对 Lakehouse 应用的注册后获得。
-* 响应类型（response\_type）：仅支持Code模式。
-* Scope（如 `openid`, `profile`, `email`）：决定可以请求的用户信息，支持多选。当使用 OpenID Connect 协议时，必须勾选 openid 选项。支持勾选“其他”后填写自定义的 scope 参数。
-* 可选扩展参数：便于根据 IdP 要求添加额外字段（如 `prompt=login`）。
-
-**配置令牌端点（Token Endpoint）**
-
-:-: ![](.topwrite/assets/image_1755161141507.png =510)
-
-**参数**：
-
-* 令牌端点URL：用于交换授权码获取令牌。通常在Lakehouse调用Idp的授权端点后，会获取访问Code。Lakehouse 会继续调用令牌端点 URL 来使用 Code 交换令牌。
-* Client Secret（非必须）：用于验证客户端身份。如 IdP 系统注册应用未颁发则此项可为空。
-* 可选扩展参数：根据 IdP 要求添加。
-
-^
-
-**配置用户信息端点（UserInfo Endpoint）**
-
-:-: ![](.topwrite/assets/image_1755161329682.png =530)
-
-**参数**：
-
-* 用户信息端点URL：用于Lakehouse调用并获取用户详细信息。
-* 身份映射配置：
-* userinfo 字段：指 Lakehouse 从 UserInfo Endpoint 获取的身份信息字段。可选 Email、Phone 或自定义字段。
-* 身份映射字段：指能够与 UserInfo 指定字段匹配的身份信息字段，可选 Email 或 Phone。注意：如果身份映射字段选择 Phone（手机号），Lakehouse 能够识别国家码为 00、+ 或不填写国家码的三种手机号格式。
-* 测试用户信息完整度：根据所选的“身份映射字段”，检查并列出当前账户下所有用户中缺失该信息或该信息重复的用户。这些用户在开启SSO后，不能正常登录。
-* 可选扩展参数：根据 IdP 要求添加。
-
-**账户管理员可同时使用云器账号登录**
-
-开启该选项，则允许具备账户管理员角色的用户继续使用用户名和密码登录，以便当SSO登录出现故障时，仍能够登录并修改账户配置。
-
-^
-
-### SAML 2.0 协议
-
-**选择协议**
-
-开启 SSO 登录后，在右侧弹窗中选择 “SAML 2.0 协议”。选择协议后，您可在协议下方看到该协议的回调地址（Assertion Consumer Service URL），如：
-
-:-: ![](.topwrite/assets/image_1755161484299.png =616)
-
-```SQL
-https://api.clickzetta.com/clickzetta-portal/sso/saml/consume?u={code}
-```
-
-请使用该地址，在 IdP 中注册应用，并记录及保存 IdP 所返回的 Entity ID 和 X.509 证书。
-
-^
-
-**填写 SSO 登录 URL**
-
-:-: ![](.topwrite/assets/image_1755161389065.png =457)
-
-**参数**：
-
-* SSO Login URL：IdP 接收 SAML Request 的端点。
-* Entity ID：IdP 中对应用的身份标识，在 IdP 内完成应用注册后可以获得。
-* X.509 证书（非必须）：用于校验签名、保证数据安全，在 IdP 内完成应用注册后可以获得。
-* Issuer（非必须）：发出 SAML 断言的实体，用于进行信任验证。
-* 测试用户信息完整度：SAML2.0协议目前仅支持以邮箱地址作为用户身份映射字段。用户信息完整度测试会检查并列出当前账户内所有用户中缺失邮箱信息或邮箱信息重复的用户。这些用户在开启SSO后，不能正常登录。
-
-**账户管理员可同时使用云器账号登录**
-
-开启该选项，则允许具备账户管理员角色的用户继续使用用户名和密码登录，以便当SSO登录出现故障时，仍能够登录并修改账户配置。
-
-***
-
-## 常见问题
-
-**问：为什么在 IdP 登录后，跳转回 Lakehouse 提示“认证失败”？**
-
-**答：**通常是映射字段（Email 或 Phone）在用户间不唯一，或未正确返回/格式有误。如果是映射字段在用户间不唯一，在认证失败的提示中会有明确提示。如未提示映射字段不唯一，则请账户管理员检查身份映射字段的配置是否正确，比如是否回传 Email 但映射为 Phone。
-
-**问：为何勾选了“账户管理员可同时使用云器账号登录”但仍不可使用用户名、密码登录？**
-
-**答：**在开启 SSO 登录且勾选“账户管理员可同时使用云器账号登录”后，仅具备账户管理员角色的用户可以使用用户名、密码登录，其他用户只能使用 SSO 方式登录。
-
-**问：是否可以通过 SDK（如 Python、JDBC）使用 SSO 登录？**
-
-**答：**当前仅支持 Web 登录。Python、JDBC 等方式当前仅支持用户名密码认证方式。

-# 数据存储加密
-
-## 概述
-
-Lakehouse 支持对存储在对象存储中的表数据进行服务端加密（Server-Side Encryption），采用 AES-256 加密算法，确保您的数据在存储层面得到安全保护。
-
-您可以根据安全合规需求，选择使用云厂商提供的托管密钥，或使用您自有的 KMS 密钥进行加密。
-
-## 加密模式
-
-Lakehouse 提供两种加密模式：
-
-| 模式         | 说明                                             |
-| ---------- | ---------------------------------------------- |
-| 托管加密（推荐）   | 使用云厂商对象存储服务提供的托管密钥进行加密，无需额外配置                  |
-| 自定义 KMS 加密 | 使用您自有的 KMS 密钥进行加密，需提供 KMS ARN（ID） 和 KMS Region |
-
-> 自定义 KMS 加密目前支持阿里云和 AWS 平台。腾讯云平台仅支持托管加密模式。
-
-## 加密范围
-
-* 您可以在工作空间级别统一开启加密，开启后该工作空间内新建的数据对象将默认加密存储。
-* 可以在任意时刻对工作空间设置开启加密，开启后不会影响工作空间中已有的表，只会对新建表应用加密。
-
-> ⚠️ 表一旦加密，无法恢复为非加密状态，请在开启前确认。
-
-## 使用方式
-
-### 在创建工作空间时开启加密
-
-1. 在创建工作空间页面，开启「存储加密」开关。
-
-2. 如果您希望使用托管加密，KMS ARN 留空即可。
-
-3. 如果您希望使用自定义 KMS 密钥：
-
-   * 填写您的 KMS 密钥 ARN。
-   * 填写 KMS Region。
-
-### 在修改工作空间时调整加密设置
-
-* 如果工作空间未使用自定义 KMS 密钥，您可以自由开启或关闭加密开关。
-* 如果工作空间已使用自定义 KMS 密钥，加密设置将被锁定，无法关闭加密或修改密钥配置。
-
-## 密钥管理
-
-* 每个数据对象在其生命周期内只能使用一个密钥，密钥不可变更。
-* 您可以创建多个密钥，在加密不同工作空间的数据对象时选用不同的密钥。
-* 使用自定义 KMS 密钥后，KMS ARN 和 KMS Region 将变为只读，不可修改。
-
-> ⚠️ 使用自定义 KMS 密钥加密后，密钥配置不可修改，加密不可关闭。请在配置前仔细确认密钥信息。
-
-> ⚠️ 请妥善保管您的自定义 KMS 加密密钥。一旦密钥遗失，Lakehouse 中使用该密钥加密的数据将永久不可读取，且无法恢复。
-
-## KMS 请求费用与缓存机制
-
-由于数仓场景下会频繁读写数据，使用自定义 KMS 密钥容易达到云厂商 KMS 服务的 QPS 请求上限，并产生大量的 KMS API 请求费用。为此，Lakehouse 采用了密钥缓存机制来减少对 KMS 的 API 调用，缓存有效期为 **5 分钟**。这意味着当 KMS 密钥被撤销或失效后，最多仍有 5 分钟的窗口期可以对加密数据进行读写。
-
-> ⚠️  建议**优先选择托管加密模式**，避免使用自定义 KMS 密钥，以免达到 KMS 请求上限影响读写性能，或产生大量的 KMS 请求费用。KMS 请求费用通常产生在您的 KMS 密钥所在的云账户中，而非 Lakehouse 账单内。
-
-## 常见问题
-
-**Q：开启工作空间加密后，历史数据会被加密吗**？
-
-不会。开启加密仅对之后新建的数据对象生效，已有数据不受影响。
-
-**Q：可以对已加密的表取消加密吗**？
-
-不可以。表的加密操作不可逆。
-
-**Q：自定义 KMS 密钥配置后可以修改吗**？
-
-不可以。一旦配置了自定义 KMS 密钥，密钥信息和加密开关均不可修改。
-
-**Q：自定义 KMS 密钥丢失了怎么办**？
-
-请务必妥善保管您的自定义 KMS 加密密钥。一旦密钥遗失，Lakehouse 中使用该密钥加密的数据将永久不可读取，且无法恢复。
-
-**Q：使用自定义 KMS 加密会产生额外费用吗**？
-
-会。每次数据读写都需要调用 KMS API 进行加解密，虽然 Lakehouse 通过 5 分钟的密钥缓存机制减少了请求次数，但在高频读写场景下仍可能产生可观的 KMS 请求费用。该费用产生在您的 KMS 密钥所在的云账户中。建议优先使用托管加密模式以避免此类费用。

-## 增量计算概述
-
-流式数据处理（Streaming data pipeline）是面向实时数据持续不断地进行数据采集、处理转换，以获得满足业务时效性要求的结果数据的一组任务集合。流式数据处理是分析人员、业务应用开展实时洞察或实时决策的基础。
-
-与周期性离线处理（Batch data pipeline）有所不同，流式数据处理通过编排实时数据采集任务和支持增量数据处理的 SQL 任务，持续产出实时更新的结果数据。处理过程中使用增量处理技术以提高处理效率，同时降低成本。
-
-云器 Lakehouse 流式数据处理过程中，总体处理流程示例如下：
-
-![](.topwrite/assets/image_1709520998068.png)
-
-流式数据处理的产品功能特性包括：
-
-| 功能特性   | 特性说明                                                                                                                                                                                                                 |
-| ------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| 实时数据加载 | **实时数据加载服务**：通过 SDK/Connector 方式提供 Streaming API，支持实时追加/更新写入、秒级可见的系统托管服务。可使用 SDK 或 Flink Connector 调用接口向目标表写入数据。**Studio 数据集成服务**：内建的数据集成工具，支持多种实时数据源（如 Kafka、数据库 CDC 等）的实时抽取，写入 Lakehouse 时通过 Streaming API 实时写入目标表。    |
-| 增量数据处理 | **动态表**：通过动态表声明式定义数据加工逻辑，支持任意 SQL 语法和算子，系统自动读取 Base 表的增量变化，自适应地通过增量/全量算法优化数据处理效率。用户可创建 1 个或多个动态表并设置调度策略，系统自动识别依赖关系并持续调度执行，大大简化实时数据处理的开发过程。注：当前最小支持 1min 的调度间隔。                                                         |
-| 变化数据捕获 | **Table Stream**：Table Stream 是系统内置的 SQL 对象类型，一个 Table Stream 创建在指定的一张表之上，可以记录该表的数据变化（CDC）信息。Table Stream 支持通过 SQL 查询获取指定两个数据版本之间的变化记录数据，例如 5 分钟前至当前这段时间的变化记录。通过 Table Stream，下游的 SQL ETL 可以非常简单易用地读取和处理表变化数据，或者将变化结果同步输出给外部系统。 |
-| 连续性调度  | 系统提供两种调度方式：
-**动态表自身设置调度周期**：通过物化视图 DDL 定义时，可通过指定 INTERVAL 关键字设置调度周期。
-**使用 Studio 调度任务调度**：在 Web IDE 中创建 SQL 任务，设置任务调度周期。此种方式同时支持对动态表、使用 Table Stream 的 SQL ETL 作业这两种任务进行调度。注：使用 Studio 调度系统，可获得更好的任务执行观测性和运维告警能力。

-# 开发动态表实现近实时增量处理
-
-> **【预览发布】** 本功能当前处于受邀预览阶段。如需试用，请通过官网联系方式联系云器科技。
-
-## 教程概述
-
-通过本教程，您将了解到如何使用Lakehouse动态表(Dynamic Table)构建一个完整的实时数据ETL加工流程。场景设计如下： 
-
-![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tutorial_dt_scenario.jpg?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=2034679003\&Signature=gewhAp%2FJ80Uu%2BFq1sNEH3fwQI54%3D)
-
- 本教程将通过数据导入任务、基于动态表实现的数据清洗转换和数据聚合任务，实现了一个分钟级延迟的流式数据处理Pipeline案例。
-
-> 本教程借助 Lakehouse Tutorial，提供了在线教程指南以及脚本导入功能。您可以在登录 Lakehouse Web 控制台后，通过 Lakehouse Tutorial 的“Lakehouse教程”入口进入，并根据在线指南引导完成教程。
-> ![](<.topwrite/assets/截屏2025-01-14 19.36.29.png>)
-
-### 入门知识
-
-动态表（Dynamic Table）是一种支持仅处理增量变化数据的对象类型，与物化视图类似。创建动态表时，您需要同时定义数据计算逻辑。通过刷新操作，可以触发动态表的计算逻辑并更新其数据。与传统的 ETL 任务相比，动态表只需要在定义时声明全量语义的计算逻辑，在刷新时则可自动进行增量计算优化。借助动态表，Lakehouse可以面向流式写入的数据进行近实时增量处理，为实时分析提供数据准备。
-
-### 教程步骤
-
-1. **数据导入**：创建原始表、持续写入用户行为数据；
-2. **开发动态表模型**：通过 Dynamic Table 分别构造数据清洗、数据聚合的加工流程。
-3. **验证加工结果**：监控由动态表构造的数据Pipeline的刷新执行状态，同时查看消费层数据表的变化情况，验证实时数据加工结果
-
-通过以上步骤，您将了解如何通过动态表在 Lakehouse 中开发流式处理任务。
-
-## 准备工作
-
-首先，创建行为日志表，通过INSERT INTO任务写入测试数据。
-
-> 为了简化教程，本教程通过周期性调度 INSERT INTO 任务模拟数据的持续写入。实际生产环境中往往使用流式写入接口实时接入数据，云器 Lakehouse 也提供 SDK/Flink Connector 等方式进行实时写入，不建议在生产任务中使用 INSERT INTO 方式写入。
-
-本教程在“开发”模块提供了创建数据表以及插入测试数据的 SQL 脚本。打开 [Tutorial_Working_With_Dynamic_Table->Step01.Preparation] 脚本文件，配置 1Min 间隔的调度策略并提交部署，以模拟实时数据导入。

-
-## Transform Layer动态表模型开发
-
-在“开发”模块打开 [Tutorial_Working_With_Dynamic_Table->Step02.Transformation_With_Dynamic_Table] 样例动态表任务文件。该动态表定义了对原始表进行清洗转换的 ETL 逻辑。
-
-请参考下图进行调度配置"运行集群"和"调度参数"：
-
-![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tutourial_dt_transform.gif?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=2034682100\&Signature=z8F6by8Cae7HFYeTggx0VR7NGxQ%3D)
-
-## 提交部署
-
-点击\[提交]按钮，将动态表模型部署到Lakehouse目标环境中，系统将根据动态表设置的刷新频率自动刷新。
-
-## Aggregate Layer动态表模型开发
-
-在“开发”模块打开 [Tutorial_Working_With_Dynamic_Table->Step03.Aggregation_With_Dynamic_Table] 样例动态表任务文件。该动态表定义了对中间层数据模型进行聚合分析的 ETL 逻辑。
-
-请参考下图进行调度配置和提交运行：
-
-![](https://studio-prod-sh.oss-cn-shanghai.aliyuncs.com/fe-asset/tutorials/resources/tutourial_dt_agg.gif?OSSAccessKeyId=LTAI5tBH4MDxrfQw7VTx4w2B\&Expires=2034682137\&Signature=jcNW0LS9R3H2TuyP9xY17097tPk%3D)
-
-## 验证增量更新结果
-
-在“开发”模块打开 Step04.Check_Data_Freshness 文件，通过执行 Query 检查自动刷新动态表的数据新鲜度。
-![](.topwrite/assets/image_1725463960356.png =754)
-如上图所示，借助动态表的自动增量刷新功能，能够以 1min 左右的时间延迟完成数据的实时处理。
-
-## 环境清理
-
-在“任务运维”模块的周期性任务列表中，下线数据导入任务；在动态表任务列表中，下线 2 个动态表模型任务。

-# VOLUME中的结构化、半结构化数据分析
-
-### 语法：
-
-```
-SELECT { <column_name>,... | * } 
-FROM [ VOLUME <volume_name> | TABLE VOLUME <table_name> | USER VOLUME ]
-    [ ( <column_name> <column_type>, <column_name> <column_type> ... ) ]
-USING CSV|PARQUET|ORC|JSON|BSON
-OPTIONS(
-  FileFormatParams
-) 
-FILES|SUBDIRECTORY|REGEXP <pattern>;
-```
-
-### 参数说明：
-
-`<column_name> <column_type> `：可选，lakehouse支持自动识别文件内的表结构信息。推荐不用填写，当指定文件中包含的列名和文件中类型需与文件中预定义的列类型相匹配，
-
-* 自动识别文件schema对于csv文件则会则会自动生成字段，字段编号以 f0 开始,目前自动识别的类型为int、double、string、bool
-* 对于 parquet、orc 格式将会根据文件中存储的字段名和类型自动识别。如果指定的文件中列的个数不一致。Lakehouse 会尝试合并，无法合并则会报错
-
-`USING CSV`：
-
-* `sep`：列分隔符，默认为 `”,“`。最多支持长度为 1 的字符，例如：`'sep'=','`
-* `compression`：配置文件压缩格式。支持的压缩格式有：`gzip/zstd/zlib`。例如：`'compression'='gzip'`
-* `lineSep`：行分隔符，默认值为`"\n"`。最多支持长度为 2 的字符，例如：`'lineSep'='$'`
-* `quote`：设置用于转义引号值的单个字符。默认值为双引号`“"“`，例如：`'quote'='"'`
-* `header`：是否解析表头，默认为 `false`。布尔类型，例如：`'header'='true'`
-* `timeZone`：配置时区，没有默认值。用于指定文件中时间格式的时区。例如：`'timeZone' = 'Asia/Shanghai'`
-* `escape`：用于转义已加引号的值中的引号，默认值为”\“，例如：`'escape'='\'`
-* `multiLine`：是否启用多行字段解析，默认为 `false`。布尔类型。当设置为 true 时，解析器会正确处理被引号包围的字段中的换行符，将其作为字段内容的一部分而非行分隔符。这对于包含 JSON 格式数据、长文本描述、向量数据等可能跨行的字段特别重要。即使字段实际不包含换行符，启用此选项也能提供更健壮的解析，特别是处理包含大量特殊字符（如逗号、引号）的复杂字符串时。例如：`'multiLine'='true'`
-
-`USING Parquet | ORC | JSON | BSON`：
-
-* 无
-
-`FILES`：指定文件。例如：`files('part-00002.snappy.parquet','part-00003.snappy.parquet')`
-
-`SUBDIRECTORY`：指定子路径。例如：`subdirectory 'month=02' `
-
-`REGEXP <pattern>`：支持使用正则表达式匹配文件。需要注意的是，正则表达式匹配的目标是文件的**完整的对象存储路径**（如 's3://cz-udf-user/volume-data/1234321.csv.gz'），而不是以文件在 Volume 对象的相对路径。
-
-![](.topwrite/assets/20250124-160418.jpeg)
-
-匹配规则：
-
-* `.` - 匹配任意单个字符，不包括换行符
-* `*` - 匹配前面的元素零次或多次，经常与`.` 配合使用，如 `.* `组合表示匹配任意字符任意次数
-* `+` - 匹配前面的元素一次或多次，经常与`.` 配合使用，如 `.+ `表示匹配任意字符一次或多次
-* `?` - 匹配前面的元素零次或一次
-* `[abc]` : 匹配 a、b 或 c 中的任意一个字符
-* `[^abc]` : 匹配除了 a、b、c 之外的任意字符
-* `[a-z]` : 匹配小写字母 a 到 z
-* `[A-Z]` : 匹配大写字母 A 到 Z
-* `[0-9]` : 匹配数字 0 到 9
-
-例如：
-
-1. `REGEXP '.*.parquet'` 匹配以 `parquet` 后缀的文件
-2. `REGEXP '.*yellow_tripdata_202[0-4]-0[23].parquet' ` 匹配包含 `yellow_tripdata_` ，年份为 `2020` 到 `2024`，月份为 `02` 或 `03`，并且以 `.parquet` 结尾的文件名
-
-## 示例：
-
-### **查询 CSV 格式文件**：

-# 同义词
-## 概述
-
-同义词（synonym）是一个数据库对象，类似于给对象起一个别名，具有以下用途：
-
-* 当您需要在schema02中查询schema01的表t，但又不希望复制数据时，可以在schema02中为表t创建一个同义词sy\_t。这样，您就可以直接在schema02中查询sy\_t，而数据将实时与schema01中的表t保持一致。这是一种高效的数据管理策略，既保证了数据的一致性，又避免了不必要的数据重复。
-* 提供一个抽象层，保护客户端应用程序免受对基础对象的名称或位置所做的更改的影响。
-
-同义词属于 schema，与 schema 中的其他对象一样，同义词的名称必须在同一 schema 下唯一。支持为以下对象创建同义词：table、table stream、dynamic table、materialized view、volume、function。
-
-
-## 操作管理
-### 创建
-
-```SQL
-CREATE  [TABLE|VOLUME|FUNCITON] SYNONYM [schema_name.] synonym_name FOR object COMMENT''
-object ::=
-workspace_name.schema_name.object_name|schema_name.object_name｜object_name
-```
-
-* TABLE|VOLUME|FUNCTION：表示同义词对象类型。
-
-  * **TABLE**：这是默认选项。用于为 table、table stream、materialized view、dynamic table 命名同义词。在这些情况下，“table”关键字是可选的。
-  * **VOLUME**：为 volume 命名同义词时，必须明确指定此关键字。如果省略，系统将默认寻找同名的表格对象。
-  * **FUNCTION**：为 function 命名同义词时，此关键字是必填项。如果未指定，系统会默认寻找同名的 table 对象。
-
-* synonym\_name:同义词名称，遵循元数据规范
-
-* object：指定基对象的名称，支持workspace\_name.schema\_name\_2.object\_name、schema\_name\_2.name格式如果省略schema则使用当前schema中的对象
-
-
-### 删除
-
-```SQL
-DROP [TABLE|VOLUME|FUNCITON] SYNONYM [ IF EXISTS ] [ schema. ] synonym_name
-```
-
-* TABLE|VOLUME|FUNCTION：表示同义词的对象类型。
-
-  * **TABLE**：这是默认选项。用于为 table、table stream、materialized view、dynamic table 命名同义词。在这些情况下，“table”关键字是可选的。
-  * **VOLUME**：为 volume 命名同义词时，必须明确指定此关键字。如果省略，系统将默认寻找同名的表格对象。
-  * **FUNCTION**：为 function 命名同义词时，此关键字是必填项。如果未指定，系统会默认寻找同名的 table 对象。
-
-* if exists：可选。仅当同义词存在时，才有条件地删除该同义词。
-
-* schema：可选，指定同义词所在的 schema。如果未指定 schema，则使用当前会话的默认 schema。
-
-### 权限
-
-创建同义词需要 `CREATE SYNONYM` 权限。
-
-```SQL
-grant create synonym  on schema  scname to user uat_test_01;
-```
-
-删除同义词需要 `DROP` 权限。
-
-```SQL
-grant drop synonym on all synonyms in schema <schemaname> to user uat_test_01;
-grant create synonym  on schema  scname to user uat_test_01;
-```
-
-### 同义词查询权限
-
-同义词的权限与基对象的权限相同。授予对同义词的权限等同于授予对应基对象的权限。同样，授予对基对象的权限等同于授予对该对象的所有同义词的权限。如果向用户授予对同义词的权限，则该用户可以在行使该权限的 SQL 语句中使用同义词名称或基对象名称。
-
-### 列出同义词
-
-```SQL
-SHOW SYNONYMS [IN {SCHEMA scname | WORKSPACE wbname}] [WHRERE <expr>]
-```
-
-## 使用示例
-
-为 table 创建同义词
-
-```SQL
---创建表
-CREATE TABLE `public`.students(
-  `name` string,
-  `class` string);
---给表创建同义词
-CREATE SYNONYM students_sy for `public`.students;
---查询同义词
-select * from students_sy;
---删除同义词
-drop synonym students_sy;
-```
-
-为 table stream 创建同义词，其语法与为 table 创建同义词相同。
-
-```SQL
-create  synonym students_stream_synonym for public.students_stream;
---删除同义词
-drop synonym students_stream_synonym;
-```
-
-为 dynamic table 创建同义词，其语法与为 table 创建同义词相同。
-
-```SQL
-create  synonym event_group_minute_sy for public.event_group_minute;
---删除同义词
-drop synonym event_group_minute_sy;
-```
-
-为 materialized view 创建同义词，其语法与为 table 创建同义词相同。
-
-```SQL
-create SYNONYM event_group_mv_sy for event_group_mv;
---删除同义词
-drop synonym event_group_mv_sy;
-```
-
-为 volume 创建同义词，其中 VOLUME 为必选关键字。如果不指定，则系统会默认寻找同名的表格对象。
-
-```SQL
-create volume synonym hz_csv_volume_sy for public.hz_csv_volume;
---删除同义词
-drop volume synonym hz_csv_volume_sy;
-```
-
-为 function 创建同义词，其中 FUNCTION 为必选关键字。如果不指定，则系统会默认寻找同名的 table 对象。
-
-```SQL
-create function synonym s_swu_udf_upper_aliyun_java_upper for public.swu_udf_upper_aliyun_java_upper;
---删除同义词
-drop function synonym s_swu_udf_upper_aliyun_java_upper;
-```
-
-## 获取同义词
-
-```SQL
-show synonyms in  public where synonym_name='students_sy';
-+--------------+-------------------------+-------------+-----------------------+
-| synonym_name |       create_time       | target_type |       target_name     |
-+--------------+-------------------------+-------------+-----------------------+
-| students_sy  | 2024-06-14 10:21:00.504 | TABLE       | ql_ws.`public`.studen |

-## Table Stream 变化数据捕获
-
-Table Stream 是云器 Lakehouse 的一种功能，用于捕获表对象的变化数据。通过定义 Table Stream 对象，您可以基于现有表来记录和追踪数据的变化。该对象利用 Lakehouse Table 的多历史版本功能，在创建时会记录源表的指定版本（或最新版本）作为初始读取位置。当您使用 SQL 查询 Table Stream 时，它将返回从初始位点到当前最新版本的所有变化记录。
-
-以下是 Table Stream 的工作原理示意图：
-
-![Table Stream工作原理](.topwrite/assets/image_1699855189257.png)
-
-Table Stream 不会存储实际数据，仅记录和维护源表的数据版本位点。仅当使用 INSERT、DELETE、UPDATE、MERGE 等 DML 语句操作 Table Stream 时，其位点才会更新至最新的数据版本。
-
-### 应用场景
-
-1. **SQL ETL 任务**：使用 Table Stream 可以简化增量数据的识别，提高 ETL 任务的处理效率。传统 ETL 任务需要通过分区过滤或 WHERE 条件过滤增量数据，这在实时化场景下可能会产生额外的系统压力和资源消耗。Table Stream 基于数据版本识别变化数据，无需额外操作和计算即可捕获增量数据，从而提高 ETL 作业的效率，节省计算开销。
-2. **实时数据提供**：类似于数据库的CDC（变更数据捕获），Lakehouse数据平台的Table Stream可以捕获变化数据，并将这些数据以明细记录的形式持续同步给下游系统。
-
-## Table Stream类型
-
-Table Stream 有两种类型：
-
-1. **STANDARD 类型**：跟踪源对象的所有 DML 变化，包括插入、更新和删除（包括表截断）。这种类型提供行级别的变化，通过连接加工所有变化的 delta 数据来提供行级别增量。Table Stream 中的 delta 变化指的是在两个事务时间点之间发生的数据变化。例如，如果在 Table Stream 的 offset 之后，有一行被插入，然后被更新，那么 delta 变化就是一个新的行。如果在 Table Stream 的 offset 之后，有一行被插入，然后被删除，那么 delta 变化就是没有这一行。换句话说，delta 变化会反映源对象的最新状态，而不是历史变化。
-2. **APPEND_ONLY 类型**：仅记录对象的 INSERT 操作的数据。update 和 delete 操作不会记录。例如，最初在表中插入了 10 行，然后在点位没有移动的时候执行 delete 操作删除 5 行，Table Stream 仍然记录 10 行操作。
-
-## 使用Table Stream
-
-### 创建Table Stream
-
-您可以使用 `CREATE TABLE STREAM` 命令来创建 Table Stream。以下是一个示例：
-
-```SQL
--- 创建测试表
-CREATE TABLE data_change_test (id INT, name STRING);
-INSERT INTO data_change_test VALUES (1, 'apple');
-ALTER TABLE data_change_test SET PROPERTIES ('change_tracking' = 'true');
--- 在data_change_test上创建table stream，获取从当前时间开始插入的增量记录
-CREATE TABLE STREAM data_change_test_stream ON TABLE data_change_test
-WITH PROPERTIES('TABLE_STREAM_MODE' = 'APPEND_ONLY');
-
--- 插入测试数据
-INSERT INTO data_change_test VALUES (2, 'banana');
-SELECT * FROM data_change_test; -- 可以查到两条记录
-SELECT * FROM data_change_test_stream; -- 查看stream可以查到一条记录，因为创建stream时指定的时间在id为1的记录之后
--- 使用dml语句消费记录
-CREATE TABLE data_change_test_offset (id INT, name STRING);
-INSERT INTO data_change_test_offset SELECT id, name FROM data_change_test_stream; -- 写入到表中
-SELECT id, name FROM data_change_test_stream; -- 查询stream数据已经被消费
-```
-
-### 删除Table Stream
-
-您可以使用 `DROP TABLE STREAM` 命令来删除 Table Stream。以下是一个示例：
-
-```SQL
-DROP TABLE STREAM IF EXISTS data_change_test_stream;
-```
-
-### Table Stream 捕获数据变化的时效性
-
-Table Stream 根据对象的元数据修改提交时间来感知变化数据。具体时效性如下：
-
-- **DML 方式修改数据**：在 DML 任务成功结束后，变化数据即可在 Table Stream 对象中可见。
-- **批量导入（Bulkload）**：在批量导入任务成功结束后，变化数据即可在 Table Stream 对象中可见。
-- **流式导入**：通过 Ingestion Service 流式 API 写入数据，默认 1 分钟提交变化，变化数据即可在 Table Stream 对象中可见。注：对于流式写入的目标表本身进行 SQL 查询时是实时可见的，这里仅约束了基于该目标表的 Table Stream 可见性的时效。
-## 动态表与 Table Stream 的关系详解
-
-在云器 Lakehouse 中，动态表（Dynamic Table）与 Table Stream 是两种相互关联且至关重要的功能，均聚焦于增量数据处理领域，但它们在具体用途及工作模式上存在显著差异。
-
-### 一、动态表的定义与特点
-
-动态表是云器 Lakehouse 特有的数据对象，具备以下关键特性：
-
-* **增量计算能力**：能精准处理增量变化数据，拥有高效的增量刷新优化机制。
-* **自动化处理**：用户仅需定义业务逻辑，无需明确指定增量处理细节（例如按分区对齐或使用最大时间戳等），系统将自动完成增量计算优化工作。
-* **定期刷新**：支持设置刷新间隔，依据预设时间周期，从基表（Base Table）获取增量数据并执行计算任务。
-* **工作原理**：以“基于历史 T0 时刻已算结果，融合 T0 至 T1 时刻增量计算，同时为 T2 及后续时刻计算做铺垫”的增量形态开展计算。
-
-### 二、Table Stream 的定义与特点
-
-TABLE STREAM 专注于捕获表的数据变化，特点如下：
-
-* **变化数据捕获**：类似于数据库的 CDC（Change Data Capture）功能，全面记录表的 DML 更改操作，涵盖插入、更新与删除行为。
-* **版本跟踪**：借助 Lakehouse Table 的多历史版本特性，可指定记录源表的特定版本（或最新版本）作为初始读取起点。
-* **两种模式**：STANDARD 模式追踪所有 DML 变化；APPEND_ONLY 模式仅记录 INSERT 操作数据。
-* **位点更新**：仅记录和维护源表数据版本位点，不存储实际数据，执行 DML 语句操作 Stream 时同步更新位点信息。
-
-### 三、两者的关系与区别
-
-#### （一）功能层次
-
-* Table Stream 属于底层机制，核心任务是捕获表的变化数据。
-* 动态表则是建立在 Table Stream 之类的底层功能之上的高级特性，侧重于利用增量计算实现数据转换与加工。
-
-#### （二）数据处理方式
-
-* TABLE STREAM 仅聚焦于变化数据的捕获，不涉及数据计算环节。
-* 动态表会对捕获到的增量数据执行计算与转换操作，生成具有业务价值的结果。
-
-#### （三）支持关系
-
-* 动态表可借助 Table Stream 机制达成增量计算目标。
-* 在云器 Lakehouse 体系中，允许在动态表基础上创建 Table Stream，由此构建起复杂且高效的增量数据处理链路。
-
-#### （四）应用场景
-
-* **Table Stream**：适用于单纯的变化数据捕获场景以及实时数据同步任务，例如在需要快速感知源表数据变动并实时传递至其他系统的场景中发挥关键作用。
-* **动态表**：适用于对增量数据进行深度加工与转换的业务场景，比如在数据仓库中对每日新增订单数据进行多维度聚合计算，生成报表所需指标数据。
-
-#### （五）底层实现
-
-两者均依托于云器 Lakehouse 的 MetaService（元数据服务），该服务负责记录每张表的历史数据版本信息，为动态表和 Table Stream 的正常运行提供基础支撑。
-
-### 四、实际应用示例
-
-在实际业务场景中，动态表与 Table Stream 经常协同工作，形成完整且强大的增量数据处理方案：
-
-* **ETL 数据处理链**：先在源表创建 Table Stream 捕获变化数据，随后利用动态表对这些变化数据执行转换与聚合操作，最终将处理后的结果准确写入目标表。
-* **多级增量计算**：搭建一系列动态表，让每个动态表依次处理前一个表产生的增量数据，构建起高效的增量数据处理流水线，实现数据的逐级加工与提炼。
-* **实时数据分析**：借助 Table Stream 实时捕获业务系统数据变动，再通过动态表开展实时分析与计算，为业务决策层及时提供准确且具时效性的数据洞察，助力企业敏捷决策。

--- 从用户行为表中随机抽取训练样本
-SELECT 
-    user_id,
-    behavior_type,
-    item_id,
-    timestamp
-FROM user_behavior 
-TABLESAMPLE ROW (20)  -- 精确 20% 随机采样
-LIMIT 1000000;
-
--- 适用：保证样本的随机性和代表性
-```
-
-#### 场景 4：统计分析采样（推荐 ROW）
-
-```sql
--- 估算平均订单金额
-SELECT 
-    AVG(total_amount) as avg_order_amount,
-    COUNT(*) as sample_count
-FROM large_orders_table 
-TABLESAMPLE ROW (5)  -- 5% 精确采样
-LIMIT 1000000;
-
--- 适用：需要统计学上严格的随机采样
-```
-
-#### 场景 5：开发环境测试数据
-
-```sql
--- 生成小规模测试数据
-CREATE TABLE test_customers AS
-SELECT * 
-FROM production_customers 
-TABLESAMPLE ROW (1000 ROWS)  -- 精确 1000 行
-LIMIT 1000;
-
--- 适用：开发和测试环境数据准备
-```
-
-### 进阶用法
-
-#### 结合 WHERE 条件
-
-```sql
--- TABLESAMPLE 必须紧跟表名，然后才能使用 WHERE 条件
-SELECT * 
-FROM orders 
-TABLESAMPLE SYSTEM (10)
-WHERE order_date >
-
-#### 结合聚合分析
-
-```sql
--- 在采样数据上进行聚合分析
-SELECT 
-    DATE_TRUNC('month', order_date) as month,
-    COUNT(*) as order_count,
-    AVG(total_amount) as avg_amount
-FROM large_orders
-TABLESAMPLE SYSTEM (5)
-GROUP BY DATE_TRUNC('month', order_date)
-ORDER BY month
-LIMIT 50;
-```
-
-#### 多表采样 JOIN
-
-```sql
--- 对多个大表采样后 JOIN
-SELECT 
-    o.order_id,
-    c.customer_name,
-    o.total_amount
-FROM orders o
-TABLESAMPLE SYSTEM (10)
-JOIN customers c
-TABLESAMPLE SYSTEM (10)
-ON o.customer_id = c.customer_id
-LIMIT 100;
-```

-### 性能对比
-
-| 数据规模      | SYSTEM 模式 | ROW 模式  | 推荐             |
-| --------- | --------- | ------- | -------------- |
-| < 1 万行    | \~10ms    | \~15ms  | ROW（精确性更重要）    |
-| 1-10 万行   | \~50ms    | \~200ms | ROW 或 SYSTEM   |
-| 10-100 万行 | \~100ms   | \~2s    | SYSTEM（性能差异明显） |
-| > 100 万行  | ~200ms   | ~10s+  | SYSTEM（性能优势巨大） |
-
-*注：实际性能取决于硬件、数据分布等因素*
-
-***
-
-## 最佳实践
-
-### 1. 如何选择采样模式
-
-< 100万行？
-│  ├─ 是 → 需要精确随机性？
-│  │     ├─ 是 → 使用 ROW 模式
-│  │     └─ 否 → 使用 SYSTEM 模式（更快）
-│  └─ 否 → 使用 SYSTEM 模式（性能优先）
-```
-
-### 2. 性能优化建议
-
-#### ✅ 推荐做法
-
-```sql
--- 1. 始终添加 LIMIT 子句
-SELECT * FROM large_table 
-TABLESAMPLE (10) 
-LIMIT 1000;  -- ✅ 限制最终返回行数
-
--- 2. 在大表上优先使用 SYSTEM
-SELECT * FROM billion_rows_table 
-TABLESAMPLE SYSTEM (1)  -- ✅ 1% 采样已足够
-LIMIT 10000;
-
--- 3. 先采样再 JOIN（减少 JOIN 数据量）
-SELECT a.*, b.*
-FROM (
-    SELECT * FROM large_table_a 
-    TABLESAMPLE (5) 
-    LIMIT 100000
-) a
-JOIN large_table_b b ON a.id = b.id
-LIMIT 1000;
-```
-
-#### ❌ 避免的做法
-
-```sql
--- 1. 在小表上使用 SYSTEM 期望精确结果
-SELECT * FROM small_table_10_rows 
-TABLESAMPLE SYSTEM (30);  -- ❌ 可能返回 0 行或 10 行
-
--- 2. 在大表上使用 ROW 不加 LIMIT
-SELECT * FROM billion_rows_table 
-TABLESAMPLE ROW (10);  -- ❌ 性能极差，可能返回 1 亿行
-
--- 3. 过度采样（接近 100%）
-SELECT * FROM large_table 
-TABLESAMPLE (95);  -- ❌ 接近全表扫描，失去采样意义
-```
-
-### 3. 采样精度建议
-
-| 需求     | 推荐采样比例    | 说明            |
-| ------ | --------- | ------------- |
-| 快速预览   | 0.1% - 1% | 足够了解数据结构      |
-| 数据质量检查 | 5% - 10%  | 平衡性能和覆盖率      |
-| 统计估算   | 10% - 20% | 保证统计显著性       |
-| 机器学习训练 | 20% - 50% | 根据数据量和模型复杂度调整 |
-
-### 4. 常见问题解答
-
-**Q1: 采样比例超过 100% 会怎样**？
-
-```sql
-SELECT * FROM test TABLESAMPLE (150) LIMIT 50;
--- A: 会报错！ClickZetta 要求采样比例必须在 0-100 之间
--- 错误信息: tablesample percentage number should be greater than 0 and less than 100
-```
-
-**Q2: 采样行数超过表总行数会怎样**？
-
-```sql
-SELECT * FROM test TABLESAMPLE (100 ROWS) LIMIT 50;  -- 表只有 10 行
--- A: 会返回全表数据（10 行）
-```
-
-**Q3: 空表采样会返回什么**？
-
-```sql
-SELECT * FROM empty_table TABLESAMPLE (50) LIMIT 50;
--- A: 返回空结果集，不会报错
-```
-
-**Q4: 视图和表的采样有差异吗**？
-
-```sql
--- 都支持，但视图可能性能稍差（需要先物化）
-SELECT * FROM my_view TABLESAMPLE ROW (10) LIMIT 50;
-```
-
-**Q5: 如何获得可重复的采样结果**？
-
-```sql
--- TABLESAMPLE 不支持 SEED，如需可重复采样：
-SELECT * FROM (
-    SELECT *, ROW_NUMBER() OVER (ORDER BY id) as rn
-    FROM my_table
-) WHERE rn % 10 = 0  -- 每 10 行取 1 行
-LIMIT 50;
-```
-
-***
-
-## 限制和注意事项
-
-### 使用限制
-
-1. **不支持的场景**
-   * ❌ 不支持在子查询的 WHERE 子句中使用
-   * ❌ 不支持在 CTE (WITH 子句) 定义中使用
-   * ❌ 不支持在物化视图定义中使用
-
-2. **语法限制**
-   * ⚠️ 必须在 FROM 子句中紧跟表名使用
-   * ⚠️ TABLESAMPLE 必须在 WHERE 子句之前
-   * ⚠️ 不能与 `FOR UPDATE` 一起使用
-   * ⚠️ 百分比采样的范围必须在 0-100 之间（不包括0和100）
-
-3. **性能注意事项**
-   * ⚠️ ROW 模式在超大表（> 1000万行）上可能非常慢
-   * ⚠️ 即使采样 1%，ROW 模式也需要扫描全表
-
-### 数据一致性
-
-* 🔄 **非确定性**：每次执行返回不同的结果
-* 📊 **统计偏差**：SYSTEM 模式在数据分布不均时可能有偏差
-* ⏱️ **时效性**：采样时看到的是当时的数据快照
-
-### 最佳实践总结
-
-| 场景    | 数据量    | 推荐模式   | 采样比例   | LIMIT      |
-| ----- | ------ | ------ | ------ | ---------- |
-| 数据预览  | 任意     | SYSTEM | 1-5%   | 100-1000   |
-| 质量检查  | 任意     | SYSTEM | 5-10%  | 1000-10000 |
-| 统计分析  | < 100万 | ROW    | 10-20% | 适当         |
-| 统计分析  | > 100万 | SYSTEM | 5-10%  | 适当         |
-| ML训练集 | < 100万 | ROW    | 20-50% | 适当         |

-# TABLE STREAM 功能介绍
-
-## 概述
-
-Table Stream 是 Lakehouse 架构中的一种对象，它能够记录对表进行的数据操作语言（DML）的更改，包括插入、更新和删除操作。Table Stream 还提供有关每次更改的元数据信息，使得用户可以利用这些信息采取相应的操作。它可以记录表中两个事务时间点之间的行级别更改，类似于关系数据库的变更数据捕获（CDC）功能。下游系统可以通过 SQL 语句消费 Table Stream，当下游的 DML 操作包含 Table Stream 时，会导致 Table Stream 的位点自动偏移。支持在 Table、Dynamic Table、Materialized View、External Table(Kafka) 创建 Table Stream.
-
-同时也支持在 External Volume 上创建 Volume Stream，用于监听外部对象存储（如 OSS）中的文件变更事件。
-
-## Table、Dynamic Table 和 Materialized View 的 TABLE STREAM OFFSET
-
-Table Stream Offset 是一种存储流的偏移量（即源对象的当前事务版本）的机制。偏移量决定了 Table Stream 返回的变化记录的范围。以下是 Table Stream Offset 的一些特点：
-
-1. 当创建 Table Stream 时，会对源对象的每一行进行一个初始快照，以初始化一个偏移量。随后，Table Stream 会记录在此快照之后发生的 DML 变化的信息。
-2. Table Stream 本身不包含任何表数据，只存储源对象的偏移量，并利用源对象的版本历史来返回变化记录。
-3. Table Stream 的偏移量可以在创建时指定，也可以在消费时更新。指定偏移量的方法使用时间戳。
-4. Table Stream 的偏移量位于源对象的两个表版本之间。查询 Table Stream 时，会返回在偏移量之后和当前时间之前提交的事务所造成的变化。
-
-## Table、Dynamic Table和Materialized View的TABLE 版本控制
-
-在 Lakehouse 中，每当对表进行插入、更新或删除操作时，都会生成一个新的表版本（也称为快照）。这些版本是不可变的，意味着一旦创建，它们就不能被修改。每个版本都包含了自上一版本以来所有数据变更的记录。Table Stream 是基于 TABLE 版本实现的。当创建一个 Stream 时，它会跟踪源表的所有后续版本，并允许用户查询自从创建 Table Stream 以来发生的变更。
-
-![](.topwrite/assets/image_1704374346251.png)
-
-上面的例子显示了一个源表在时间线上有10个已提交的版本。Table Stream的偏移目前在表版本v3和v4之间。当查询（或消费）流时，返回的记录包括从表版本v4开始，即表时间线中流偏移之后的版本，到v10结束，即时间线中最近提交的表版本，包括这两个版本之间的最小更改集。
-
-## Table、Dynamic Table和Materialized View的TABLE STREAM支持的类型
-
-1. STANDARD 模式：在此模式下，可以跟踪源对象的所有 DML 变化，包括插入、更新和删除（包括表截断）。这种模式提供行级别的变化，是通过将所有变化的 delta 数据进行连接加工来提供行级别增量。Table Stream 中的 delta 变化指的是在两个事务时间点之间发生的数据变化。
-2. APPEND\_ONLY 模式：只记录对象的 INSERT 操作的数据。对于 UPDATE 和 DELETE 操作不会进行记录。
-
-## Table、Dynamic Table和Materialized View的TABLE STREAM 记录数据的范围
-
-这个时间范围取决于源对象的数据保留期和数据延长期（DATA\_RETENTION\_DAYS）。数据保留期是指源对象的历史数据可以通过 Time Travel 查询的时间长度。
-
-## 消费 TABLE STREAM
-
-Table Stream 的消费者是指下游 SQL 中含有 DML 语句则会消费 Table Stream 数据。当下游的 DML 操作包含 Table Stream 时，会使 Table Stream 的位点自动偏移。执行 DQL 操作不会使位点偏移，例如 SELECT 语句。一个源对象可以有多个 stream 同时跟踪它的变化。每个 Table Stream 都可以有不同的 offset，即不同的起始时间点。每个 Table Stream 都可以被不同的消费者（consumer）使用，例如不同的任务、脚本或其他机制。消费者可以通过执行 DML 事务来消费 Table Stream 中的变化数据，从而更新 Table Stream 的 offset。
-
-## TABLE STREAM 中的元数据字段
-
-当查询 Table Stream 时，返回的结果集中包含附加的元数据列，包含变化的类型、提交的版本、和提交的时间。具体字段如下：
-
-* `__change_type`：包含 DML 操作（INSERT、DELETE、UPDATE\_BEFORE、UPDATE\_AFTER）
-* `__commit_version`：数据提交的版本
-* `__commit_timestamp`：数据提交的时间
-
-## 注意事项
-
-* 创建 Table Stream 之前，必须在基表上执行以下操作开启变更跟踪：`ALTER TABLE table_name set PROPERTIES ('change_tracking' = 'true');`
-* 通过[实时上传数据](java_reference/realtime-upload.md)写入的数据一分钟之后才可以读取，Table Stream 只能读取已经提交的数据。实时任务写入的数据需要等待 1 分钟才能确认，所以 Table Stream 也要等 1 分钟才能看到。

-CREATE table stream test_stream ON TABLE test_table
-WITH
-  PROPERTIES ('TABLE_STREAM_MODE' = 'APPEND_ONLY');
-
--- 插入一些数据到测试表
-INSERT INTO test_table VALUES
-  (1, 'Alice', 20),

-## Volume Stream 功能介绍
-
-Volume Stream 是 Table Stream 的一种特殊形式，它构建在 External Volume 的 Directory Table 之上。Directory Table 是 External Volume 开启目录功能（DIRECTORY = (ENABLE = TRUE)）后自动维护的一张元数据表，记录了 Volume 中所有文件的路径、大小、修改时间等信息。Volume Stream 通过追踪 Directory Table 的数据变化，来感知外部存储（如对象存储 OSS、S3 等）中文件的新增与删除事件。
-
-与普通 Table Stream 追踪用户表的 DML 变更不同，Volume Stream 追踪的是文件层面的变化。Directory Table 的更新依赖云厂商的消息队列服务（如阿里云 MNS、AWS SQS 等）将对象存储的事件通知实时推送至系统，从而驱动 Directory Table 刷新，进而使 Volume Stream 感知到文件的新增与删除。
-
-典型使用场景包括：应用日志分析、IoT 设备数据接入、图片/音视频元数据提取、多源文件归档等。通过 Volume Stream 作为增量驱动器，配合调度任务实现"只处理新增/变更文件"的高效增量模式，避免全量扫描带来的性能与成本开销。
-
-***
-
-## 前置准备
-
-在创建 Volume Stream 之前，需要完成以下云服务及数据库对象的准备工作（以阿里云-杭州 region 为例）。
-
-> 注意：当前版本(2026.03)仅支持阿里云和 AWS
-
-### STEP-1：创建 MNS 队列
-
-1. 进入 [阿里云 MNS 控制台](https://mns.console.aliyun.com/region/cn-hangzhou/queues)。
-2. 创建队列，输入名称（例如 `volume-stream-20251203`），选择**普通队列**，其他配置保持默认。
-
-### STEP-2：创建 OSS 事件通知
-
-1. 打开 OSS Bucket 管理页，选择 **数据处理 → 事件通知**。
-2. 创建规则：
-   * 根据需要选择事件类型（建议勾选 `ObjectCreate:*`、`ObjectRemoved:*`）。
-   * 根据需要配置对象匹配前缀/后缀。
-   * 通知目标选择 STEP-1 中创建的 MNS 队列。
-
-### STEP-3：创建 RAM 策略和角色
-
-**a. 创建权限策略**（[策略管理页](https://ram.console.aliyun.com/policies)），参考配置如下：
-
-```json
-{
-  "Version": "1",
-  "Statement": [
-    {
-      "Effect": "Allow",
-      "Action": [
-        "oss:GetObject",
-        "oss:HeadBucket",
-        "oss:PutObject",
-        "oss:DeleteObject",
-        "oss:ListObjects"
-      ],
-      "Resource": [
-        "acs:oss:oss-cn-hangzhou:<账号ID>:<bucket名称>",
-        "acs:oss:oss-cn-hangzhou:<账号ID>:<bucket名称>/*"
-      ]
-    },
-    {
-      "Effect": "Allow",
-      "Action": [
-        "mns:GetQueueAttributes",
-        "mns:SetQueueAttributes"
-      ],
-      "Resource": "acs:mns:cn-hangzhou:<账号ID>:/queues/<队列名称>"
-    },
-    {
-      "Effect": "Allow",
-      "Action": [
-        "mns:DeleteMessage",
-        "mns:ReceiveMessage",
-        "mns:PeekMessage",
-        "mns:BatchPeekMessage"
-      ],
-      "Resource": "acs:mns:cn-hangzhou:<账号ID>:/queues/<队列名称>/messages"
-    }
-  ]
-}
-```
-
-**b. 创建角色**（[角色管理页](https://ram.console.aliyun.com/roles)）：
-
-1. **信任主体类型**：选择"云账号"。
-2. **信任主体名称**：选择"其他云账号"，输入 Lakehouse 平台的账号 ID（`1384322691904283`）。
-3. **角色名称**：例如 `CzVolumeStreamRole`。
-4. 将 STEP-3a 中创建的权限策略授予该角色。
-
-### STEP-4：创建 Storage Connection
-
-**a. 创建连接**：
-
-```sql
-CREATE STORAGE CONNECTION conn_hz
-    TYPE OSS
-    REGION = 'cn-hangzhou'
-    ROLE_ARN = 'acs:ram::<账号ID>:role/<角色名称>'
-    ENDPOINT = 'oss-cn-hangzhou-internal.aliyuncs.com';
-```
-
-**b. 获取 External ID，用于后续配置信任策略**：
-
-```sql
-DESCRIBE CONNECTION conn_hz;
-```
-
-记录返回结果中的 `externalId` 字段值。
-
-**c. 更新角色信任策略**（将 `externalId` 填入）：
-
-```json
-{
-  "Statement": [
-    {
-      "Action": "sts:AssumeRole",
-      "Condition": {
-        "StringEquals": {
-          "sts:ExternalId": "<describe connection 返回的 externalId>"
-        }
-      },
-      "Effect": "Allow",
-      "Principal": {
-        "RAM": [
-          "acs:ram::1384322691904283:root"
-        ]
-      }
-    }
-  ],
-  "Version": "1"
-}
-```
-
-***
-
-## Volume Stream 语法
-
-### 创建 External Volume
-
-在创建 Volume Stream 之前，必须先创建一个带有消息通知配置的 External Volume：
-
-```sql
-CREATE [OR REPLACE] EXTERNAL VOLUME <volume_name>
-  LOCATION '<oss://bucket/path/>'
-  USING CONNECTION <connection_name>
-  NOTIFICATION = (
-    QUEUE_TYPE = 'ALICLOUD_MNS',
-    QUEUE_NAME = '<volume-stream-20251203>', -- STEP-1 创建的队列名称
-    VIRTUAL_CLUSTER = 'DEFAULT'
-  )
-  DIRECTORY = (ENABLE = TRUE)
-  RECURSIVE = TRUE;
-```
-
-**参数说明**：
-
-* `<volume_name>`：External Volume 的名称。
-* `LOCATION`：OSS 存储路径，格式为 `oss://<bucket>/<prefix>/`。
-* `USING CONNECTION <connection_name>`：关联 STEP-4 中创建的 Storage Connection。
-* `NOTIFICATION`：消息通知配置块。
-  * `QUEUE_TYPE`：消息队列类型，当前支持 `ALICLOUD_MNS`。
-  * `QUEUE_NAME`：STEP-1 中确认的 MNS 队列名称。
-  * `VIRTUAL_CLUSTER`：虚拟集群名称，默认填写 `DEFAULT`。
-* `DIRECTORY = (ENABLE = TRUE)`：开启目录模式，Volume Stream 依赖此配置。
-* `RECURSIVE = TRUE`：递归监听路径下所有子目录的文件变更。
-
-### 创建 Volume Stream
-
-```sql
-CREATE [OR REPLACE] STREAM <name>
-  ON VOLUME <volume_name>;
-```
-
-**参数说明**：
-
-* `<name>`：Volume Stream 的名称。
-* `<volume_name>`：要监听的 External Volume 名称。
-
-***
-
-## 注意事项
-
-* 当前版本(2026.03) 仅支持阿里云和 AWS。
-* RAM 角色的信任策略中必须正确配置 `sts:ExternalId`，否则 Lakehouse 平台无法代入该角色读取 MNS 消息和 OSS 文件。
-* Volume Stream 只能读取已完成上传的文件。由于事件通知存在一定的传递延迟（通常约 1 分钟），文件上传后需等待约 1 分钟才能在 Volume Stream 中查询到对应的变更记录。
-* 与 Table Stream 类似，Volume Stream 通过消费点位（offset）记录已处理的事件位置，消费行为通常是一个 DML 操作（非 SELECT），每次消费后点位会向前推进，避免重复消费。
-
-***
-
-## 示例：增量解析 OSS 图片
-
-以下示例展示了一个 Volume Stream 配置流程，用于监听 `sh-oss-derek` bucket 下 `dish-images/` 目录中的文件新增与删除事件。利用图像识别函数只消费 `INSERT` 和 `UPDATE_AFTER` 两种事件（新增图片 + 替换图片），跳过 DELETE 和 UPDATE\_BEFORE，调用 AI 函数识别后写入结果表，DML 执行完自动推进消费点位。
-
-> 注意：此案例中用到的云厂商角色 ARN，图像识别函数等需要自定义，系统并未默认提供。
-
-### 1. 创建 Storage Connection
-
-```sql
-CREATE STORAGE CONNECTION conn_sh_oss
-  TYPE OSS
-  REGION = 'cn-shanghai'
-  ROLE_ARN = 'acs:ram::1450476637304722:role/czvolumestreamrole' -- 需替换成自己的 RoleARN
-  ENDPOINT = 'oss-cn-shanghai.aliyuncs.com';
-```
-
-### 2. 获取 External ID 并更新信任策略
-
-```sql
-DESCRIBE CONNECTION conn_sh_oss;
-```
-
-将返回的 `externalId`（例如 `EOKskml6SMldYOb9`）填入角色的信任策略后保存。
-
-### 3. 创建基础对象
-
-```sql
--- 1. 创建 External Volume（OSS 图片桶，开启 MNS 事件通知）
-CREATE EXTERNAL VOLUME vol_dish_images
-  LOCATION 'oss://sh-oss-derek/dish-images/'
-  USING CONNECTION conn_sh_oss
-  NOTIFICATION = (
-    QUEUE_TYPE    = 'ALICLOUD_MNS',
-    QUEUE_NAME    = 'cz-queue-mns-ossevent',
-    VIRTUAL_CLUSTER = 'DEFAULT'
-  )
-  DIRECTORY = (ENABLE = TRUE)
-  RECURSIVE = TRUE;
-
--- 2. 创建识别结果表
-CREATE TABLE IF NOT EXISTS dish_recognition_results (
-    file_path          VARCHAR        COMMENT '图片相对路径',
-    file_url           VARCHAR        COMMENT '图片完整 OSS 地址',
-    file_size          BIGINT         COMMENT '文件大小（字节）',
-    last_modified_time TIMESTAMP      COMMENT '文件最后修改时间',
-    recognized_content VARCHAR        COMMENT 'AI 识别结果',
-    change_type        VARCHAR        COMMENT '触发事件类型 INSERT/UPDATE_AFTER',
-    commit_version     BIGINT         COMMENT 'Stream 消费版本号',
-    processed_at       TIMESTAMP      COMMENT '处理时间'
-);
-
--- 3. 创建 Volume Stream（STANDARD 模式，可感知新增和替换）
-CREATE STREAM IF NOT EXISTS str_dish_images
-  ON VOLUME vol_dish_images
-  WITH PROPERTIES ('TABLE_STREAM_MODE' = 'STANDARD');
-```
-
-### 4. 增量消费
-
-```
--- 增量识别节点：只处理 INSERT（新图）和 UPDATE_AFTER（替换图），自动推进 offset
-INSERT INTO dish_recognition_results
-SELECT
-    relative_path   AS file_path,
-    url   AS file_url,
-    size   AS file_size,
-    last_modified_time,
-    public.fc_image_to_text('dish_recognition', url) AS recognized_content,
-    __change_type  AS change_type,
-    __commit_version  AS commit_version,
-    current_timestamp() AS processed_at
-FROM str_dish_images
-WHERE __change_type IN ('INSERT', 'UPDATE_AFTER')  -- 只处理新增和替换，跳过 DELETE / UPDATE_BEFORE
-  AND (
-       lower(relative_path) LIKE '%.jpg'
-    OR lower(relative_path) LIKE '%.jpeg'
-    OR lower(relative_path) LIKE '%.png'
-    OR lower(relative_path) LIKE '%.webp'
-  );                       
-```
-
-### 5. 查询识别结果
-
-```
--- 查看最新识别结果
-SELECT
-    file_path,
-    recognized_content,
-    change_type,
-    processed_at
-FROM dish_recognition_results
-ORDER BY processed_at DESC
-LIMIT 20;
-
--- 统计每类菜品识别数量
-SELECT
-    recognized_content,
-    COUNT(*) AS cnt
-FROM dish_recognition_results
-GROUP BY recognized_content
-ORDER BY cnt DESC;
-
-```

-| ------ | ----------------------------------------------------------------------------------------------------------------------------------------- |
-| 任务     | 简单节点：单个具体的任务类型，例如 SQL、Python 等                                                                                                              |
-|        | 复杂流程类节点：由多个节点组成的一组节点，例如组合节点等。复杂流程类节点中的参数、调度配置项统一进行配置管理。                                                                                      |
-| 任务组    | 任务组是云器 Lakehouse 提供的一个虚拟管理概念。可以将任务添加至任务组内进行集中的管理，包括可视化拖拽编排依赖关系、配置任务组参数、批量设置调度、批量提交等操作。**说明**：若您需要对一组任务进行 DAG 方式的拖拽管理，或者对一批任务链路进行复制改造，建议使用任务组功能。 |
-
-## 依赖关系：节点依赖
-
-依赖关系是挂载在节点上的。无论是简单节点还是复杂流程类节点，均以一个独立节点作为依赖点。
-
-**注意**：无论是在任务下直接创建任务节点，还是在任务组内进行统一管理，依赖关系始终是在任务节点级别上的，即节点之间的依赖，不存在任务组之间建立依赖的能力。
-
-^
-
-## 场景说明
-
-* 支持用户直接在「任务」下创建各类任务节点，并通过调度配置中的调度依赖来创建节点之间的依赖关系进行开发。
-* 同时也支持用户在「任务组」下新建或添加已有的节点，对一批任务进行组织编排，包括配置任务组级别的参数、可视化拖拽任务之间的依赖关系等。
-
-| **开发方式** | **目标用户**               | **场景优势**                                 | **场景使用限制与差异**                                                   |

-# 任务组
-
-## 概念
-
-任务组是开发板块内用以管理一组任务列表的虚拟业务管理组。您可以使用任务组对一系列任务进行组织编排，包括添加/创建任务节点、创建任务节点之间的依赖关系、配置任务组参数以及统一批量提交的操作。
-
-本文为您介绍如何创建、编辑、提交任务组，以及任务组的复制操作。
-
-## 使用限制
-
-1）任务组内仅支持添加/创建周期任务，暂不支持实时任务。
-
-2）任务组参数只有在被提交发布后，任务节点中引用的该参数才能使用任务组参数配置的变量值参与执行。
-
-例如，若任务组参数是 aaa=2023，任务里使用了该参数，但是任务组未提交。那么任务在做周期执行时，实例参数将显示为空。
-
-3）一个任务节点只能归属于一个任务组。
-
-4）下游链路复制：只能复制在该工作空间下的所有节点，若该下游链路有其他工作空间的任务节点，不会被复制出来。
-
-## 应用场景
-
-### 场景一：任务批量复制与依赖关系管理
-
-当您需要对一组有依赖关系的任务进行批量复制，并在新的任务中创建新的依赖关系时，可以使用任务组复制功能实现。
-
-![](.topwrite/assets/91c6efc6cd/3c6fcb545a6b507a072943955259ae593b4f1892.jpeg =700)
-
-将需要复制并建立新依赖关系的任务组添加至任务组1内，对任务组1进行复制操作后，复制得到的任务组2将包含以下内容：
-
-1. 对任务组1内所有任务的批量复制。
-2. 任务组1内有依赖关系的节点（如节点B、C、D、E、F）在任务组2内会维持原来的依赖关系。
-3. 任务组外但与组内节点有依赖关系的节点（如节点A、G），将维持原本的依赖关系。
-
-### 场景二：任务链路改造与自定义变量批量修改
-
-当您需要对当前任务链路中的任意一分支进行改造，同时需要批量修改任务里的自定义变量时，可以通过节点下游链路复制功能结合任务组功能实现。
-
-![](.topwrite/assets/91c6efc6cd/f8dfd42b7ace23593c3f7d3d79bff8eb46d2a1f9.jpeg =751)
-
-在任意一个节点上（该节点可以是归属于某一个任务组，也可以是独立的），点击「下游链路复制」时，会将该节点及其下游所有节点进行批量复制。
-
-## 创建任务组
-
-创建任务组前，您可以结合自身的业务情况，先规划设计好符合自身业务诉求的业务流程。以下为创建任务组的详细步骤。
-
-1）创建任务组
-
-**方式一**：单击左侧导航栏的「开发」；鼠标悬浮在+上，点击「任务组」
-
-**方式二**： 单击左侧导航栏的「工作区」；鼠标悬浮在新建按钮上，点击「任务组」
-
-2）在新建任务组对话框中，输入任务组名称
-
-3）点击确定
-
-![](.topwrite/assets/image_1722251763584.png =434)
-
-创建完成后：
-
-* 您可以在当前任务组内管理任务节点，包括新建/添加已有任务到该任务组内
-* 任务组内的所有任务开发完成后，可直接提交任务组至生产环境。
-
-## 编辑任务组
-
-支持用户在列表和 DAG 两种模式下设计任务组内管理的任务节点和依赖关系。
-
-![](.topwrite/assets/image_1722251928404.png)
-
-1）新建/添加节点：两种模式下均支持在任务组创建新的任务节点，或添加已有的任务至任务组内。
-
-* **DAG图模式**
-
-  * 添加已有任务：点击右侧「添加已有任务」后，可将列表中的任务拖至DAG画布区域；
-  * 添加新任务：在「添加新任务」下方，拖拽任意一个任务节点至画布区域后，会弹出该节点的创建弹窗。用户输入任务名称，以及所在目录后，即成功创建一个新节点至该任务组上。
-
-DAG 图模式下，点击右侧下方「已添加的任务」即可在图中高亮显示出该任务节点。
-
-* **列表模式**
-
-  * 点击列表模式右上角「添加」按钮后，可选择是添加已有任务还是新任务。
-
-新建/添加节点成功后，您需要进入该节点的操作界面进行代码的编辑工作。
-
-2）创建任务之间的依赖关系：
-
-* DAG图模式下：可以通过拖拽依赖线的方式设置节点调度依赖。当然，您也可以进入节点的调度配置界面，来手动编辑节点依赖关系。
-* 列表模式下新建的节点，其调度依赖可根据代码血缘关系自动或手动设置。
-
-3）任务组参数：任务组下的全局参数。当任务组提交至生产环境后，这些参数会自动作用于引用它们的任务节点上。在任务组参数生效前已提交的任务节点，需要重新提交后才可以引用该参数。
-
-* 点击任务组内操作区域的「参数」tab，进入任务组参数配置界面中。
-* 点击新建按钮，在弹窗内输入参数名称和参数取值。内置参数取值详情请见[任务参数](task_param.md)
-
-  ![](.topwrite/assets/image_1722252018555.png =497)
-
-创建任务组参数后，使用方法如下：
-
-* 在任务节点的SQL代码中输入${任务组参数名称}，或在调度配置的参数配置中输入参数名；
-
-  ![](.topwrite/assets/image_1722252076469.png =496)
-
-* 在「取值来源」下拉框里选择任务组参数
-
-  ![](.topwrite/assets/image_1722252102342.png =472)
-
-创建且引用任务组参数后：
-
-* 任务组提交至生产环境后，应用的任务节点才可以使用任务组参数的参数值
-* 变更后的任务组参数如需在任务节点里生效，需重新提交任务节点
-
-### 批量提交调度时间
-
-可使用批量编辑调度时间的功能，批量修改任务组内所有（或选定）任务的调度时间，以减少逐个配置的操作成本。具体操作如下：
-
-1）点击批量修改调度时间
-
-* DAG编辑模式下：鼠标悬浮在批量按钮上时，选择「编辑调度时间」
-  ![](.topwrite/assets/image_1736303777548.png =498)
-* 列表模式下：选择需要批量修改的目标任务后，点击编辑调度时间。
-
-2）批量编辑调度时间
-选择批量修改的调度时间，这里操作同任务调度里的调度配置，具体操作可参考[任务开发调度](taskdevelop.md)
-![](.topwrite/assets/image_1736303843406.png =499)
-
-3）确定提交批量操作
-
-## 提交任务组
-
-任务组编辑创建完成后，需要将其提交至生产环境，其管理的任务才可以引用任务组内的参数信息。同时，任务组也提供了批量提交任务节点的功能。
-
-1）点击右上角提交按钮，弹出任务组提交弹窗，同时可以支持批量提交任务组内的任务列表。
-
-2）DAG图模式下，鼠标悬浮在批量按钮上方，显示批量提交任务，该功能仅支持批量提交任务组内的任务，不会将任务组本身的参数和管理信息提交至生产环境中。
-
-## 相关问题
-
-Q1：为什么任务组提交后，提交按钮不能再次点击了
-
-任务组提交后，若未发生任何变更（即状态未变为“已提交，有修改”），则不支持再次提交。若需要批量提交任务组内的任务信息，可通过两种方式提交
-
-方案一：在任务内直接操作提交
-
-方案二：在任务组DAG图模式下，点击批量操作下的批量提交任务
-
-任务组状态变更条件：
-
-* 对任务组内的任务进行增删的操作
-* 对任务组参数进行增删改查的操作

-# 任务参数
-
-> 特别注意：参数功能目前处于灰度阶段，完整的功能仅对部分客户开放使用。可使用文末的方式来验证是否支持。
-
-## 什么是任务参数
-
-### 为什么需要参数？
-
-在日常数据开发中，我们经常遇到这样的场景：
-
-* 每天处理前一天的数据：`WHERE dt = '2023-09-21'`
-* 每月统计上月数据：`WHERE month = '2023-08'`
-* 查询特定城市数据：`WHERE city = 'Shanghai'`
-
-如果把日期、城市等信息写死在代码中，任务运行时就无法动态适应变化。**任务参数**就是为了解决这个问题而设计的。
-
-### 参数的核心价值
-
-* **动态替换**：任务运行时自动替换参数值。
-* **灵活配置**：支持常量、时间表达式、系统参数。
-* **复用性强**：一次定义，多处使用。
-* **易于维护**：修改参数无需改动代码逻辑。
-
-### 基本概念
-
-| 分类   | 概念名称     | 含义                                                 | 示意                                   |
-| ---- | -------- | -------------------------------------------------- | ------------------------------------ |
-| 参数定义 | 自定义参数    | 指用户在代码中，自定义输入，引用的参数。其格式固定为 ${自定义参数名}               | ${my\_param}                         |
-| 参数赋值 | 常量       | 指固定不变的取值，比如字符串和数字，用于给自定义参数赋值                       | abcd 或 1234                          |
-| 参数赋值 | 系统内置参数   | 指由系统内置的一系列参数表达式，用来方便用户获取需要通过计算获取的动态的信息，比如任务实例的计划时间 | sys\_plan\_datetime                  |
-| 参数赋值 | 系统内置时间函数 | 指由系统内置的一系列函数表达式，用于对时间做一些常用的转换计算                    | add\_months(yyyy-MM-dd HH\:mm\:ss,N) |
-
-## 快速开始
-
-### 三步快速上手
-
-**第1步：在代码中使用参数**
-
-```SQL
-SELECT * FROM sales_table WHERE city = '${city}' AND dt = '${yesterday}';
-```
-
-**第2步：配置参数取值**
-点击"参数"按钮，系统会自动识别出 `city` 和 `yesterday` 两个参数，为它们赋值：
-
-* `city` = `Shanghai`
-* `yesterday` = `$[yyyy-MM-dd, -1d]`
-
-**第3步：运行验证**
-点击“运行”，系统会将参数替换后执行：
-
-```SQL
-SELECT * FROM sales_table WHERE city = 'Shanghai' AND dt = '2023-09-21';  
-
--- 假设今天是2023-09-22
-```
-
-### 关键要点
-
-* 参数格式固定为：`${参数名}`。
-* 参数名只能包含字母、数字、下划线。
-* 参数要在定义中使用内置参数或时间表达式等赋值，然后在代码中引用。不能在代码中直接引用内置参数。
-* 参数替换时，只替换 `${}` 内的内容。
-* 如需在SQL中加引号，需自行添加，比如：`'${city}'`。
-
-## 参数类型与作用域
-
-系统提供两种参数类型，支持不同的使用场景：
-
-### 任务参数
-
-**特点**：
-
-* 作用范围：仅当前任务
-* 使用场景：任务特定的配置
-
-**适用情况**：
-
-* 单个任务独有的参数
-* 需要精细控制的场景
-* 临时性的参数配置
-
-**创建方式**：
-方式一：在脚本中输入 ${自定义参数} 后，系统会自动将自定义参数添加至「参数」弹窗内。
-方式二：点击「参数」按钮，在弹窗内输入信息。
-
-![](.topwrite/assets/image_1740658949338.png =700)
-
-| 配置项  | 说明           | 示例                           |
-| ---- | ------------ | ---------------------------- |
-| 参数名称 | 参数的唯一标识      | city、yesterday               |
-| 取值来源 | 选择"任务"或"任务组" | 任务                           |
-| 参数取值 | 参数的实际值       | Shanghai、$\[yyyy-MM-dd, -1d] |
-| 加密取值 | 勾选后取值以密文显示   | 用于密码等敏感信息                    |
-| 是否忽略 | 勾选后不进行参数替换   | 将 ${var} 作为普通文本              |
-
-**示例**：
-```SQL
--- 在某个具体任务中使用
-
-SELECT * FROM table WHERE status = '${task_status}';
-```
-
-### 任务组参数
-
-**特点**：
-
-* 作用范围：任务组内所有任务
-* 使用场景：多任务共享的配置
-
-**适用情况**：
-
-* 多个任务共用的参数（如项目代码、环境标识）
-* 全局性的配置（如数据库名称）
-* 需要统一管理的参数
-
-**创建方式**：
-在任务组页面点击「参数」，在弹框中点击「新建」，填写参数名称、参数值。
-
-![](/.topwrite/assets/image_1760699887513.png =680)
-
-如果要在具体任务中使用任务组参数，需要在任务参数定义的取值来源中做显式切换，指明该参数取值来源于任务组。
-
-![](/.topwrite/assets/image_1760699557999.png =680)
-
-**示例**：
-```SQL
--- 任务组参数：db_name = warehouse_prod
-
--- 任务A
-SELECT * FROM ${db_name}.table_a;
-
--- 任务B
-SELECT * FROM ${db_name}.table_b;
-
--- 两个任务都使用同一个db_name参数
-```
-
-## 参数两种配置方法
-
-### 方法一：基于代码自动识别
-
-直接在脚本中输入 `${参数名}`，系统会自动识别并添加到参数列表。
-
-**优点**：快速、直观，参数名不易拼写错误。
-```SQL
--- 输入以下代码
-SELECT * FROM table WHERE city = '${city}' AND dt = '${dt}';
--- 系统自动识别出 city 和 dt 两个参数
-```
-
-### 方法二：手动创建后再使用
-
-点击"参数"按钮，在弹窗中点击"新建"，手动输入参数信息。
-
-**优点**：可以提前定义参数，适合规划性强的场景。
-
-## 参数在不同运行方式下的作用效果
-
-### 临时运行（点击"运行"按钮）
-
-* 弹窗提示输入参数值
-
-  ![](/.topwrite/assets/image_1761284431760.png =680)
-
-* 本次运行生效，不影响已保存的参数配置
-
-* 适合调试和验证
-
-### 周期调度运行（自动定时调度）
-
-* 使用已保存的参数配置
-* 根据调度时间动态计算参数值
-* 适合生产环境
-
-## 系统内置参数
-
-系统预置了一系列常用参数，可直接用于参数赋值，无需手动计算。
-
-请特别注意内置参数无法在代码中被直接引用。
-
-### 日期时间类参数
-
-| 参数名                  | 格式                    | 说明            | 示例（基准时间2023-09-22 18:00:00） |
-| -------------------- | --------------------- | ------------- | --------------------------- |
-| bizdate              | yyyyMMdd              | 业务日期（计划时间-1天） | 20230921                    |
-| sys\_biz\_day        | yyyy-MM-dd            | 业务日期          | 2023-09-21                   |
-| sys\_biz\_datetime   | yyyy-MM-dd HH\:mm\:ss | 业务时间          | 2023-09-21 18:00:00             |
-| sys\_plan\_day       | yyyy-MM-dd            | 计划日期          | 2023-09-22                   |
-| sys\_plan\_datetime  | yyyy-MM-dd HH\:mm\:ss | 计划时间          | 2023-09-22 18:00:00             |
-| sys\_plan\_timestamp | 13位时间戳                | 计划时间戳（毫秒）     | 1695463200000               |
-
-### 任务信息类参数
-
-| 参数名              | 说明    | 示例         | 注意事项     |
-| ---------------- | ----- | ---------- | -------- |
-| sys\_task\_id    | 任务ID  | 1002       | 仅调度运行时支持 |
-| sys\_task\_name  | 任务名称  | demo\_task | 仅调度运行时支持 |
-| sys\_task\_owner | 任务负责人 | UAT\_TEST  | 仅调度运行时支持 |
-
-### 使用示例
-
-```SQL
--- 示例1：使用业务日期
-SELECT * FROM table WHERE dt = '${dt}';
--- 参数配置：dt = sys_biz_day
--- 调度时间2023-09-22，实际执行：WHERE dt = '2023-09-21'
-
--- 示例2：使用计划时间戳
-SELECT * FROM table WHERE create_time >= ${start_ts};
--- 参数配置：start_ts = sys_plan_timestamp
--- 结果：WHERE create_time >= 1695463200000
-
--- 示例3：Python任务中使用
-task_id = '${task_id}'
-print(f"当前任务ID: {task_id}")
--- 参数配置：task_id = sys_task_id
-```
-
-### 使用建议
-
-1. **业务日期场景**：优先使用 `bizdate` 或 `sys_biz_day`
-2. **需要时分秒**：使用 `sys_biz_datetime` 或 `sys_plan_datetime`
-3. **时间戳计算**：使用 `sys_plan_timestamp`
-4. **审计日志**：使用 `sys_task_*` 系列参数记录任务信息
-

-
-## 时间表达式详解
-
-时间表达式是参数系统的核心功能，支持灵活的时间格式化和偏移计算。
-
-### 基础语法
-
-```Plain
-$[时间格式]                    # 基本格式化
-$[时间格式, 偏移量]             # 带偏移量
-$[时间格式, 偏移1, 偏移2, ...]  # 多个偏移量
-```
-
-### 时间格式元素
-
-时间表达式遵循 **ISO-8601 标准**，严格区分大小写。
-
-| 元素   | 含义             | 示例     |
-| ---- | -------------- | ------ |
-| yyyy | 四位年份           | 2023   |
-| yy   | 两位年份           | 23     |
-| MM   | 两位月份（01-12）    | 9      |
-| dd   | 两位日期（01-31）    | 22     |
-| HH   | 24小时制小时（00-23） | 18     |
-| mm   | 分钟（00-59）      | 59     |
-| ss   | 秒（00-59）       | 49     |
-| .SSS | 毫秒             | 0.377  |
-| ZZ   | 时区             | +08:00 |
-
-### 常用格式组合
-
-```SQL
-$[yyyy-MM-dd]                         → 2023-09-22
-$[yyyyMMdd]                           → 20230922
-$[yyyy/MM/dd]                         → 2023/09/22
-$[yyyy-MM-dd HH:mm:ss]                → 2023-09-22 18:00:00
-$[yyyyMMddHHmmss]                     → 20230922180000
-$[HH:mm:ss]                           → 18:00:00
-$[yyyy-MM-dd HH:mm:ss.SSSZZ]          → 2023-09-22 18:00:00.377+08:00
-```
-
-### 常见错误
-
-```SQL

-WHERE dt = '${yesterday}'
-GROUP BY order_id;
-```
-
-**参数配置**：
-
-* `yesterday` = `$[yyyy-MM-dd, -1d]`
-
-**说明**：假设任务在2023-09-22执行，参数替换为 `2023-09-21`
-
-***
-
-### 场景2：生成月报（上月数据统计）
-
-**需求**：每月1号生成上月的销售报表
-
-```SQL
--- SQL任务
-SELECT 
-    product_id,
-    SUM(sales_amount) as total_sales,
-    COUNT(DISTINCT user_id) as unique_users
-FROM sales_table
-WHERE dt BETWEEN '${last_month_start}' AND '${last_month_end}'
-GROUP BY product_id;
-```
-
-**参数配置**：

-* `last_month_end` → `2023-08-31`
-
-***
-
-### 场景3：周报统计（上周一到周日）
-
-**需求**：每周一生成上周的用户活跃报告
-
-```SQL

-FROM user_login_log
-WHERE dt BETWEEN '${last_week_monday}' AND '${last_week_sunday}'
-GROUP BY DATE(login_time)
-ORDER BY login_date;
-```
-
-**参数配置**：
-
-* `last_week_monday` = `first_day_of_week('yyyy-MM-dd', '-1w')`
-* `last_week_sunday` = `last_day_of_week('yyyy-MM-dd', '-1w')`
-
-**说明**：假设在2023-09-25（周一）执行
-
-* `last_week_monday` → `2023-09-18`（上周一）

-
-```SQL
--- SQL任务
-SELECT 
-    order_id,
-    order_time,
-    amount
-FROM orders
-WHERE order_timestamp >
-
-**错误用法**：
-```SQL
--- ❌ 缺少引号导致SQL语法错误
-WHERE city = ${city}        # 替换后：WHERE city = Shanghai（语法错误）
-
--- ❌ 多余的引号
-WHERE id = '${user_id}'     # 替换后：WHERE id = '12345'（类型错误）
-```
-
-### Q4：临时运行和调度运行的参数有什么区别？
-
-| 维度     | 临时运行         | 调度运行                  |
-| ------ | ------------ | --------------------- |
-| 参数来源   | 弹窗手动输入       | 参数配置中的取值              |
-| 生效范围   | 仅本次运行        | 每次调度都生效               |
-| 时间基准   | 点击运行的时刻      | 调度计划时间                |
-| 任务信息参数 | 不支持（无实际任务实例） | 支持 sys\_task\_\* 系列参数 |
-| 适用场景   | 调试、验证        | 生产环境自动运行              |
-
-**注意**：临时运行时输入的参数值**不会保存**到参数配置中，参数配置中只保存参数赋值的逻辑（表达式或常量）。
-
-***
-
-### Q5：如何验证参数配置是否正确？
-
-**使用简单查询验证**
-
-```SQL
-SELECT '${lastDay}' as lastDay;
-```
-
-参数配置：`lastDay = add_days('yyyy-MM-dd', -1)`
-
-**查看执行日志** 执行后查看日志中的实际执行SQL，确认参数是否正确替换。
-
-如果返回昨天的日期（如 `2023-09-21`），说明参数功能正常。
-
-***
-
-### Q6：Python任务中如何使用参数？
-
-**示例**：
-```Python
-# 定义参数（使用字符串变量）
-yesterday = '${yesterday}'
-start_ts = ${start_ts}
-task_name = '${task_name}'
-
-# 使用参数
-print(f"处理日期：{yesterday}")
-print(f"开始时间戳：{start_ts}")
-
-# 在SQL中使用
-sql = f"""
-    SELECT * FROM table 
-    WHERE dt = '{yesterday}'
-      AND create_time >= {start_ts}
-"""
-```
-
-**参数配置**：
-
-* `yesterday` = `$[yyyy-MM-dd, -1d]`
-* `start_ts` = `biz_timestamp()`
-* `task_name` = `sys_task_name`
-
-**注意**：
-
-* 字符串类型参数需要加引号：`'${yesterday}'`
-* 数值类型参数不加引号：`${start_ts}`
-
-***
-
-### Q7：如何处理月末日期偏移问题？
-
-**问题**：1月31日减1个月应该是12月31日，但有些月份没有31日
-
-**解决方案**：使用 `last_day_of_month()` 函数
-
-```SQL
--- 推荐写法（明确要上月最后一天）
-SELECT '${last_month_end}' as last_month_end;
--- 参数配置：last_month_end = last_day_of_month('yyyy-MM-dd', '-1mon')
--- 始终返回上月最后一天
-```
-
-***
-
-### Q8：如何调试复杂的参数表达式？
-
-**技巧1：逐步验证**
-
-```SQL
--- 先验证基础表达式
-SELECT '${base_date}' as base_date;
--- base_date = $[yyyy-MM-dd]
-
--- 再添加偏移量
-SELECT '${offset_date}' as offset_date;
--- offset_date = $[yyyy-MM-dd, -1mon]
-
--- 最后添加多个偏移量
-SELECT '${final_date}' as final_date;
--- final_date = $[yyyy-MM-dd, -1mon, -7d]
-```
-
-**技巧2：使用注释说明**
-
-```SQL
-SELECT 
-    '${report_start}' as report_start,  -- 上月第一天
-    '${report_end}' as report_end,      -- 上月最后一天
-    '${last_year_date}' as last_year_date  -- 去年同期
-FROM table;
-```
-
-在参数配置中也添加说明，方便后续维护。
-
-***
-
-### Q9：参数加密后如何修改？
-
-**步骤**：
-
-1. 点击参数配置，找到加密的参数
-2. 取消勾选"加密取值"
-3. 参数值会明文显示，可以修改
-4. 修改完成后重新勾选"加密取值"
-
-**注意**：加密仅用于显示，不影响参数的实际使用。
-
-^
-
-***
-
-## 附：如何确认是否支持完整参数功能
-
-使用以下验证SQL：
-
-```SQL
-SELECT '${lastDay}' as lastDay;
-```
-
-**参数配置**：
-
-* `lastDay` 赋值填写 `add_days('yyyy-MM-dd', -1)`
-
-**校验逻辑**：
-```
-检查参数替换、任务执行返回结果是否正常。
-如果返回正常，则说明在灰度范围内、支持完整的参数功能，否则说明不支持。
-假定当前日期是2023-11-12，正常的返回值会是2023-11-11。

-# 任务调度依赖关系
-
-## 概述
-
-任务调度依赖是不同任务节点之间，形成上下游依赖关系的配置操作。既支持同工作空间内配置任务依赖关系，也支持配置跨工作空间依赖其它工作空间下的任务节点。您可根据实际业务逻辑所需的依赖场景，配置任务的上下游依赖，
-
-## 依赖特殊说明
-
-**当前的依赖限制**
-
-* 不支持任务类型：实时同步、多表实时同步、动态表、流式SQL。
-* 不允许配置环形依赖。
-* 当被依赖的节点未上线时，下游节点不支持上线。
-* 若当前节点被其他任务所依赖，且该节点下游的周期调度任务处于正常调度中，则当前节点不允许直接下线。
-
-## 依赖配置入口
-
-![](.topwrite/assets/image_1756107294537.png)
-进入具体的任务后，点击任务工具栏「调度」，进入调度配置弹窗页面。
-点击调度依赖可选择依赖的任务，配置依赖策略等行为操作。
-
-## 实例依赖关系说明
-
-云器Lakehouse支持分钟、小时、天三种类型的调度任务互相依赖，调度类型不同，任务执行的周期数不同。当周期任务运行时，下游周期实例会依赖上游周期实例。
-当前系统内提供三种依赖方式：
-
-**默认依赖**：系统内默认的挂载关系为区间依赖，即用下游任务实例的起止时间范围去与上游实例的起止时间范围进行重叠判断后，并基于以下规则判断具体依赖的实例范围：
-
-* 同周期：即同周期进行依赖。
-* 大周期依赖小周期：比如天任务依赖小时任务，下游实例覆盖上游任务几个实例，就依赖哪几个上游实例。
-* 小周期依赖大周期：比如小时任务依赖天任务，下游实例被上游哪个实例覆盖，就依赖哪个上游实例。
-
-**向前依赖**：下游任务实例寻找上游任务实例依赖时只会依赖距离其定义时间往前（等于或早于本实例的定时时间）的所有上游实例。
-
-**向前就近依赖**：当用户选定向前就近依赖时，下游任务实例寻找上游任务实例依赖时会遵循就近原则，即依赖距离其定时执行时间最近（等于或早于本实例的定时时间）的上游实例。
-
-> 注意：下游任务一旦挂载依赖，则需要满足两个条件才可以触发实例的正常运行，即上游任务实例正常运行成功，以及达到自身的调度时间。

-| 调度等待时长     | 任务实例在到达调度定时时间后，若等待时长超过设定值，且仍处于等待上游任务结束的状态（即未进入运行状态，也未运行结束），系统将直接判定该任务实例运行失败，以防止其长时间不运行、产生调度堆积。              |
-| 延迟运行空跑跳过时长 | 基于任务实例进入运行状态的时间与配置的定时时间之间的差异进行判断。若该差值超过设定时间，择直接进行空跑跳过操作，并将该实例状态置为成功。                                        |

-
-#### 符号使用示例
-
-- 年份:
-  - `yyyy`: 四位数年份表示法，例如 2022。
-  - `yy`: 两位数年份表示法，例如 22。
-
-- 月份:
-  - `M`: 单位数月份表示法，例如 3、12。
-  - `MM`: 双位数月份表示法，例如 03、12。
-
-- 当月天数:
-  - `d`: 单位数当月日期表示法，例如 5、20。
-  - `dd`: 双位数当月日期表示法，例如 05、20。
-
-- 小时 (24小时制):
-  - `H`: 单位数24小时制小时表示法，例如 1、23。
-  - `HH`: 双位数24小时制小时表示法，例如 01、23。
-
-- 分钟:
-  - `m`: 单位数分钟表示法，例如 4、59。
-  - `mm`: 双位数分钟表示法，例如 04、59。
-
-- 秒:
-  - `s`: 单位数秒钟表示法，例如 8、59。
-  - `ss`: 双位数秒钟表示法，例如 08、59。
-
-- 毫秒/微秒:
-  - `S`: 支持1-9位数字，表示毫秒（前3位）、微秒（中间3位）和纳秒（后3位）。CZ目前只支持微秒精度，因此解析时间字符串时纳秒会被丢弃，生成时间字符串时纳秒部分则会置零。不足9位时，从右向左降低精度。
-
-#### 示例
-
-以下是一些使用上述符号的日期时间格式示例：
-
-- `yyyy-MM-dd HH:mm:ss.SSSS`: 2022-01-10 10:05:02.1232
-- `yyyy/MM/dd HH:mm:ss.SSSS`: 2022/01/10 10:05:0

-# Time Travel
-
-Time Travel功能可以让您像时间旅行一样访问时间窗口中的任何时间点的数据，包括已更新或删除的数据、恢复已删除的表或恢复已过期的表。通过Time Travel，您可以轻松查看历史版本数据，从而更好地了解数据的变更历史。
-
-![Time Travel示意图](.topwrite/assets/image_1708936936399.png)
-
-如上图所示，表中原来有一条数据，经过insert、update、delete等操作后，共有四个版本。当指定的版本在v0-v1之间时，Time Travel将返回v0的数据。通过指定版本，您可以查看历史版本数据。
-
-## Time Travel功能支持的操作
-
-* 使用undrop命令恢复已删除的表
-* 使用restore命令恢复现有表或dynamic表到指定版本
-* 查询表或dynamic表已更新或删除之前的数据
-* 查看表或dynamic表的版本历史
-* 创建表流（table stream）或使用table\_changes获取表或dynamic表的变化
-
-# Time Travel保留期限设置
-
-Time Travel保留期限决定了您可以访问多久以前的数据。例如，如果Time Travel保留期限设置为7天，那么您可以访问过去7天内的任何时间点的数据。超过7天后，您将无法使用Time Travel访问过期的数据，且数据会被物理删除。
-Lakehouse表的历史状态默认保留周期1天(24小时），您可以通过Time Travel查询1天内的历史版本。请注意如果设置的时间更长存储费用会增加
-
-如需保留更长周期的历史版本，您可以为每个表设置不同的数据保留周期，以满足不同的业务需求。num的设置范围为0-90。
-
-  * ```SQL
-    ALTER TABLE tablename SET PROPERTIES ('data_retention_days'='num');
-    ```
-
-## 恢复删除的对象
-
-请参考[恢复删除数据](UNDROP-TABLE.md)文档，了解如何使用undrop命令恢复已删除的表。
-
-## 恢复数据到指定版本
-
-请参考[RESTORE命令](restore.md)文档，了解如何使用restore命令将现有表或dynamic表恢复到指定版本。
-
-## 查询历史数据
-
-请参考[TIME TRAVEL](TIMETRAVEL.md)文档，了解如何查询表或dynamic表已更新或删除之前的数据。

-
-# 测试过程
-
-在测试中，我们选择了TPC-DS基准测试中的103个复杂SQL查询，对10TB的数据集进行性能测试。测试结果包括每个查询在云器Lakehouse和Spark SQL中的执行时间，以及两者的性能对比。
-
-## Spark SQL
-
-在元数据服务中创建TPC-DS数据表，使用Parquet文件格式，分区设置与Lakehouse保持一致。
-
-同时，从云器Lakehouse中导出TPC-DS 10TB测试数据，以数据文件形式保存至对象存储服务，以保证双方的测试数据一致。然后在Spark中使用INSERT INTO语句读取数据文件并写入Spark定义的数据表中。
-
-* 运行TPC-DS 103个查询时，Spark添加了以下参数：
-
-```SQL
---spark 生产环境大作业必调参数之一。在处理TPCDS-10T规模的数据时，若使用默认的最大并发数200，会因规模偏小而导致大量task内存占用过高，并且极易触发shuffle spill，进而使Spark运行缓慢。经测试，将该参数值调整为2000后，观察到spill大幅减少。因此，我们决定采用2000这一参数值，以优化Spark的运行性能。
-set spark.sql.shuffle.partitions = 2000;spark默认值为200
-```
-
-
-## 云器Lakehouse
-
-### 创建集群和表
-
-使用云器Lakehouse XLARGE Virtual Cluster在阿里云OSS上进行测试，所有表均使用默认存储格式。
-
-```SQL
-create vcluster if not exists XLARGE_CLUSTER vcluster_size='XLARGE' vcluster_type='Analytics'  AUTO_RESUME=TRUE AUTO_SUSPEND_IN_SECOND=300 min_replicas=1 max_replicas=1;
-```
-
-### 建表语句
-
-```SQL

-# 测试过程
-
-## Trino
-
-TPC-H数据以CSV格式文件上传至对象存储服务，使用EMR集群通过外表方式导入到Hive内表（Parquet格式，LZ4压缩）。Hive内表与云器Lakehouse表使用相同的分桶和排序设置。
-
-所有数据表通过ANALYZE收集统计信息后，执行TPC-H的查询。
-
-## 云器Lakehouse
-
-### 创建集群
-
-使用云器Lakehouse XLARGE VCluster在阿里云OSS上进行测试，所有表均使用Parquet存储格式，并设置了相同的分桶和排序规则。

-# 场景案例1：基于静态分区的ETL任务增量改造（无维度表或维度表不变）
-
-## 业务背景
-
-针对传统按天调度的全量批处理任务（T+1模式），通过动态分区表技术实现增量处理优化。改造后可达成：
-
-* 数据时效提升：支持小时级/分钟级调度间隔
-* 资源利用率优化：减少冗余计算约60%-80%
-* 运维效率提升：支持分区级数据修复与回溯
-
-## 场景特征
-
-适用对象需满足：
-
-1. 业务时间对齐自然日：如订单交易、日志采集等典型日切场景
-2. 固定调度时段：建议在数据就绪时段（如00:30-01:00）集中处理
-3. 分区字段标准化：源表需包含标准日期分区字段（如event_day/pt/ds等）
-
-## 改造方案：使用分区动态表
-
-#### 1. 创建分区动态表
-
-在创建分区动态表时，通过定义参数 `SESSION_CONFIGS()['dt.args.event_day']` 来指定源表要扫描的分区或者分区范围。此参数在 SQL 加工逻辑中使用，通过 `SESSION_CONFIGS()['dt.arg.xx']` 进行定义，表示查询源表的分区字段。
-
-* 参数格式：`SESSION_CONFIGS()['dt.args.xx']`，其中 `xx` 是自定义的参数名称，必须以 `dt.args.` 开头，以避免与系统内部字段冲突。
-* 等价表达：与传统调度中的 `SELECT * FROM source_table WHERE pt = ${bizdate}` 等价。例如，`SESSION_CONFIGS()['dt.args.pt']` 等价于 `pt = ${bizdate}`。
-
-#### 2. 动态表刷新
-
-在刷新动态表时，使用以下命令指定分区值：
-
-```SQL
-REFRESH DYNAMIC TABLE target_table PARTITION (pt = ${bizdate});
-```
-
-* 对应传统操作：等同于传统的 `INSERT OVERWRITE target_table PARTITION (pt = ${bizdate})`。
-
-## 改造实施步骤
-
-### 将离线任务转换为增量任务
-
-本节将指导用户如何将原有的离线任务转换为增量任务，以实现更高效的数据处理。以下是一个基于“传统数据库”的具体操作步骤，适用于业务逻辑按天对齐和按天调度刷新的场景。
-
-#### 步骤1：任务改造
-
-原始SQL
-
-```SQL
-CREATE TABLE target PARTITIONED BY (ds);
-
--- 20250101 调度
-SQL :=
-INSERT OVERWRITE TABLE target (ds='20250101')
-SELECT * 
-FROM 
-    src_1 AS t1
-LEFT OUTER JOIN 
-    src_2 as t2 WHERE t2.ds = '2025/01/01' AND t2.category = 'A'
-ON t1.id = t2.id;
-
--- 20250102 调度
-SQL :=
-INSERT OVERWRITE TABLE target (ds='20250102')
-SELECT * 
-FROM 
-    src_1 AS t1 
-LEFT OUTER JOIN 
-    src_2 as t2 WHERE t2.ds = '2025/01/02' AND t2.category = 'A'
-ON t1.id = t2.id;
-```
-
-首先，需要将原始SQL中的所有由调度引擎传入的参数`${bizdate}`替换为`SESSION_CONFIGS()['dt.args.bizdate']`。
-
-1. 找到连续的两个调度任务，如上文所示 20250101 调度 和 20250102 调度
-
-2. 找到其中变化的部分 如 上文两处标记为黄色的部分
-
-3. 将其替换为 SESSION\_CONFIG()\['dt.args.xx']
-
-   1. 值得重点注意的是，**SESSION_CONFIG()['dt.args.xx'] 返回的结果是string**，如果变量是int需要用SQL进行类型转换，例如 CAST(SESSION_CONFIG()['dt.args.xx'] AS BIGINT)
-   2. 并且设置上刷新的语句
-   3. ```sql
-      CREATE DYNAMIC TABLE target (columns...)
-      PARTITIONED BY (ds)
-      --INSERT OVERWRITE TABLE target (ds='20250101')
-      AS
-      --SELECT *
-      -- 分区列需要出现在最后的schema里，才能保证列的个数是对齐的
-      SELECT t1.id, t1.col1, t2.col1, format(t1.ds) -- YYYY-MM-DD ==> YYYYMMDD
-      FROM 
-          src_1 AS t1 
-      LEFT OUTER JOIN 
-       --   src_2 as t2 WHERE t2.ds = '2025/01/02' AND t2.category = 'A'
-          src_2 as t2 WHERE t2.ds = SESSION_CONFIG()['dt.args.date2'] AND t2.category = 'A'
-      ON t1.id = t2.id;
-      ```
-
-#### 步骤2：调度刷新命令
-
-```SQL
-set dt.args.date1 = {$date1};
-set dt.args.date2 = {$date2};
-REFRESH DYNAMIC TABLE target partition(ds = {$date1});
-```
-
-### 增量任务数据补数和运维
-
-在某些情况下，用户可能需要向已有的分区中补充数据。
-
-#### 方法1：向源表补充数据
-
-用户可以直接向源表中补充数据。这些补充的数据将通过相应的REFRESH任务自动反映到Dynamic Table（DT）中。
-
-**操作步骤**：
-
-1. 直接向源表插入或更新数据。
-2. 执行REFRESH任务，以将更改同步到DT中。
-
-#### 方法2：使用DML语句直接向DT补充数据
-
-用户可直接运用DML语句向DT的指定分区插入数据。**但需注意，若上游数据未发生变动，下一次刷新操作将执行全量刷新，此时数据会恢复至未修改前的状态。**
-
-**操作步骤**：
-
-1. 使用DML语句向DT的特定分区插入数据。
-2. 请注意，直接修改DT将导致下一次该分区的全量刷新。如果用户不希望出现全量刷新的结果，应避免调度该分区的REFRESH任务。
-
-**示例代码**：
-
-```SQL
-set cz.sql.dt.allow.dml=true;
-INSERT INTO DYNAMIC TABLE incremental_dt  VALUES (...);
-```
-
-**注意事项**：
-
-* 直接向DT插入的数据将参与DT的下游计算。如果下游的老分区不需要这些数据，请不要调度涉及这些数据的分区的REFRESH任务。
-* 其他未受影响的分区仍然可以进行增量刷新。
-
-# 场景案例2：基于动态分区的ETL任务优化方案（无维度表或维度表不变）
-
-## 场景特征
-
-1. 动态数据特征：源数据存在历史分区更新可能性
-2. 时间窗口要求：业务需要持续处理N天内可能变更的数据
-3. 维度表情况：维度表不变、无需保留历史维度，或不存在维度表。
-
-## 将离线任务转换为增量任务
-
-```sql
-CREATE TABLE target PARTITIONED BY (ds);
-
--- 20250101 调度
-SQL :=
-INSERT OVERWRITE TABLE target (ds)
-SELECT * 
-FROM 
-    src_1 AS t1 WHERE t1.ds = '2025-01-01'
-LEFT OUTER JOIN 
-    src_2 as t2 WHERE t2.ds = '2025/01/01' AND t2.category = 'A'
-ON t1.id = t2.id;
-
--- 20250102 调度
-SQL :=
-INSERT OVERWRITE TABLE target (ds)
-SELECT * 
-FROM 
-    src_1 AS t1 WHERE t1.ds = '2025-01-02'
-LEFT OUTER JOIN 
-    src_2 as t2 WHERE t2.ds = '2025/01/02' AND t2.category = 'A'
-ON t1.id = t2.id;
-```
-
-1. 如果用户原本就是一个依赖调度系统填参数的静态分区调度的作业，不建议改写为动态分区
-2. 如果用户希望 老分区的数据在某个阶段后便不再改变 了，也不建议改写为动态分区
-3. 动态分区改写时，主要遵循的原则是：一切计算都由数据驱动。即每一条数据都应该按照定义好的计算逻辑，和其他数据发生交互，并且写入对应的目标分区中。
-4. 过滤条件中需要根据实际业务需求加个窗口过滤，比如1周/1个月/3个月/一年，防止DT数据持续增加，时间长了之后可能会影响性能。
-
-接下来我们来尝试把上述的静态分区的SQL改写为动态分区
-
-```SQL
-CREATE DYNAMIC TABLE target (COLUMNS...)
-PARTITIONED BY (ds)
---INSERT OVERWRITE TABLE target (ds)
-SELECT *, DATE_FORMAT(STR_TO_DATE(t1.ds, '%Y-%m-%d'), '%Y%m%d')
-FROM 
- --   src_1 AS t1 WHERE t1.ds = '2025-01-02'
-    src_1 AS t1
-LEFT OUTER JOIN 
- --   src_2 as t2 WHERE t2.ds = '2025/01/02' AND t2.category = 'A'
-    src_2 as t2
-ON t1.id = t2.id 
-AND t1.ds = DATE_FORMAT(STR_TO_DATE(t2.ds, '%Y/%m/%d'), '%Y-%m-%d')
-WHERE t2.category = 'A';
-```
-
-## 增量任务数据补数和运维
-
-1. 需要先对源表数据进行补数，如果表是来自于外部数据需要使用数据集成工具重新同步，
-
-2. 历史数据补数：
-
-   1. 影响：补进来的数据会作为增量数据进行加工，这一批次加工会变慢，影响最新数据加工的新鲜度。
-
-   2. 建议：
-
-      1. 建议提前扩大计算资源保证加工性能，补数进行分批操作，减少一次计算的量；
-      2. 另外就是可以补数完，触发一次全量加工
-
-3. 维度表修改：
-
-   1. 影响：维度表修改会直接影响增量计算，如果修改的内容影响加工的范围过大，可能会影响加工性能
-
-   2. 建议：
-
-      1. 如果影响范围小，直接修改即可，增量计算自动识别加工
-      2. 如果影响范围大，可修改完进行一次全量加工
-      3. 如果影响代码逻辑（比如增加列，要加计算逻辑），则需要修改dt逻辑，重新全量计算
-
-# 场景案例3：按天分区任务（需要保留历史维度）
-
-## 业务背景
-
-针对维度表持续变化的按天分区ETL场景，通过构建维度表实时同步体系与动态加工链路，实现事实表与维度表的增量协同计算。改造后可达成：
-
-* 维度数据时效性提升：维度变更延迟从T+1缩短至分钟级
-* 跨表数据一致性保障：建立维度-事实表的版本对齐机制
-* 资源消耗降低：避免维度表全量同步带来的冗余计算
-
-## 场景特征
-
-适用对象需满足：
-
-1. 混合数据处理模式：维度表需支持实时更新+历史版本保留
-2. 版本对齐要求：事实表处理需绑定对应时间点的维度快照
-
-## 将离线任务转换为增量任务

-
-## 改造实施步骤
-
-### 一、维度表实时化改造
-
-#### 1. 多源同步架构
-
-* **实时同步层**：如果数据来源是外部系统（如MySQL），通过StudioCDC捕获工具实现源库多表实时同步。实时同步要求和源端字段必须保持一致，因此如果维度表含有分区，需要新建一张维度表存储每日维度分区快照。
-
-### 二、加工任务增量改造
-
-* **版本绑定**：事实表的事件时间自动关联对应日的维度分区。
-
-加工任务增量改造示例如下，假设t1是日维度分区表，t2是事实表：
-
-```sql
-CREATE DYNAMIC TABLE target (columns...)
-PARTITIONED BY (ds)
---INSERT OVERWRITE TABLE target (ds='20250101')
-AS
-SELECT *
--- 分区列需要出现在最后的schema里，才能保证列的个数是对齐的
-SELECT t1.id, t1.col1, t2.col1, format(t1.ds) -- YYYY-MM-DD ==> YYYYMMDD
-FROM 
---    src_1 AS t1 WHERE t1.ds = '2025-01-02'
-    src_1 AS t1 WHERE t1.ds = SESSION_CONFIG()['dt.args.date2']
-LEFT OUTER JOIN 
- --   src_2 as t2 WHERE t2.ds = '2025/01/02' AND t2.category = 'A'
-    src_2 as t2 WHERE t2.ds = SESSION_CONFIG()['dt.args.date3'] AND t2.category = 'A'
-ON t1.id = t2.id;
-```
-
-## 增量任务数据补数和运维
-
-1. **历史数据补数**：通过补数功能按天修改输入表数据，之后按天刷新Dynamic Table即可。增量计算分区表可以按天刷新，不影响当天最新数据的计算。
-
-2. **修改维度表**：
-
-   1. 如果影响范围小，直接修改即可，增量计算自动识别加工
-   2. 如果影响范围大，可修改完进行一次全量加工
-   3. 如果影响代码逻辑（比如增加列，要加计算逻辑），则需要修改dt逻辑，重新全量计算
-
-# 特殊场景下的增量计算效果说明
-
-在以下场景中，增量计算仍然可以正常执行，但性能优化效果可能有限。在最坏情况下，计算性能可能与全量计算相当。建议在这些场景下进行实际测试，评估增量计算的收益后再决定是否采用。
-
-1. **Outer Join 右表频繁变更**：数据查询中包含大量的 Outer Join，且参与 Outer Join 的右表数据处于频繁变更状态，每次变化数据量大于5%。
-2. **大量排序操作**：查询操作里存在大量数据排序需求，例如使用了 Order by 子句。
-3. **Window 函数排序与大分区**：Window 函数需要对数据进行排序（RowNumber=1 的情况除外），并且增量数据中包含多个数据量特别大的 Partition。
-4. **数据聚集性较差**：数据缺乏良好的聚集性，无法通过 Join key、Aggregate key、Window partition key 等清晰地将冷数据和热数据区分开来。

-# 使用DynamicTable开展实时ETL
-
-## 教程概述
-
-通过本教程，您将了解如何使用 Lakehouse 动态表（Dynamic Table）对流式数据进行实时 ETL。
-
-本教程包含以下步骤：
-
-* 环境准备：通过样例数据集获取系统预置的实时数据表
-* 创建 ETL 任务：通过 Dynamic Table 分别构造数据清洗、数据聚合的加工流程
-* 验证加工结果：查看消费层数据表的变化情况，验证实时数据加工结果
-
-## Step 1. 准备工作
-
-本教程将利用 Lakehouse 样例数据集中具备实时数据的表作为数据源表（阿里云上海区域可用），同时创建一个用于测试的计算集群和一个测试用的 schema，用于保存 ETL 过程中产生的数据表。
-
-```sql
---  1.计算资源和DEMO环境准备
-create vcluster if not exists dt_refresh_vc vcluster_size='XSMALL' vcluster_type='GENERAL';
-
-USE vcluster dt_refresh_vc;
-
-CREATE SCHEMA cz_tutourials;
-use cz_tutourials;
-
--- 2.查看原始数据：样例数据集ecommerce_events_multicategorystore_live提供实时电商行为样例数据
-select * from clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live
-where event_time between current_timestamp() - INTERVAL 5 minutes and current_timestamp() limit 20;
-```
-
-查看原始数据明细，可以看到表 `ecommerce_events_multicategorystore_live` 持续有实时数据插入。
-![](.topwrite/assets/image_1716287777109.png)
-
-## Step 2.通过定义动态表实现数据清洗
-
-参考如下语句创建动态表 `ecommerce_events_multicategorystore_enriched`。该动态表将每分钟刷新一次，对每分钟的增量数据进行数据清洗转换。为了减少加工数据规模，对历史数据进行过滤，仅处理指定时间之后的新增数据。
-
-刷新任务将根据 DDL 中定义的刷新间隔自动运行，并使用 `refresh_vc` 指定的计算资源执行。
-
-```sql
-
--- 以当前时间（以当前时间替换下方时间过滤条件，过滤规则可选）作为原始表过滤条件，创建包含数据清洗逻辑的物化视图,配置分钟级别调度
-CREATE DYNAMIC TABLE IF NOT EXISTS ecommerce_events_multicategorystore_enriched
-REFRESH
-    interval '1' minute
-    vcluster dt_refresh_vc
-AS
-SELECT
-event_time,
-CAST(SUBSTRING(event_time,0,19) AS TIMESTAMP) AS event_timestamp, 
-SUBSTRING(event_time,12,2) AS event_hour, 
-SUBSTRING(event_time,15,2) AS event_minute, 
-SUBSTRING(event_time,18,2) AS event_second, 
-event_type,
-product_id, 
-category_id,
-category_code,
-brand,
-CAST(price AS DECIMAL(10,2)) AS price, 
-user_id, 
-user_session,
-CAST(SUBSTRING(event_time,0,19)AS date) AS event_date 
-FROM clickzetta_sample_data.ecommerce_events_history.ecommerce_events_multicategorystore_live
-where event_time > TIMESTAMP '2024-05-21 18:18:35.117561';
-refresh DYNAMIC TABLE ecommerce_events_multicategorystore_enriched;
-```
-
-## Step 3.通过定义动态表实现数据聚合分析
-
-根据业务需求，这里模拟对表 `ecommerce_events_multicategorystore_enriched` 进行产品收入、转化率、DAU 等主题的数据聚合加工。
-
-```sql
--- 分析指标加工
--- 产品收入分析,配置分钟级别调度
-CREATE DYNAMIC TABLE IF NOT EXISTS Product_Grossing
-REFRESH
-    interval '1' minute
-    vcluster dt_refresh_vc
-AS 
-select event_date,product_id,sum(price) sum_price from ecommerce_events_multicategorystore_enriched
-group by event_date,product_id;
-refresh DYNAMIC TABLE Product_Grossing;
-
---产品的转化率  Conversion Rates Per Product,配置分钟级别调度
-CREATE DYNAMIC TABLE IF NOT EXISTS Conversion_Rates_Per_Product
-REFRESH
-    interval '1' minute
-    vcluster dt_refresh_vc
-AS
-select event_date,product_id,
-count(case when event_type='purchase' then 1 else null end) num_of_sales,
-count(case when event_type='view' then 1 else null end) num_of_views,
-count(case when event_type='purchase' then 1 else null end)/count(case when event_type='view' then 1 else null end) cvr
-from ecommerce_events_multicategorystore_enriched
-GROUP BY event_date,product_id;
-refresh DYNAMIC TABLE Conversion_Rates_Per_Product;
---日活跃用户(DAU),配置分钟级别调度
-CREATE DYNAMIC TABLE IF NOT EXISTS DAU
-REFRESH
-    interval '1' minute
-    vcluster dt_refresh_vc
-AS
-select event_date,count(distinct user_id) as DAU from ecommerce_events_multicategorystore_enriched  
-group by event_date;
-refresh DYNAMIC TABLE DAU;
-```
-
-## Step 4.验证实时ETL加工结果
-
-上述动态表在创建后，平台将自动进行调度刷新。当源头表有新数据写入时，最终加工出的聚合表将自动按照聚合逻辑进行更新。
-
-```sql
--- 查询分析
--- 当日收入前10产品分析
-select product_id,sum_price as revenue from Product_Grossing where event_date=CURRENT_DATE() order by sum_price desc limit 10;
--- 当日转化率前10产品分析
-SELECT product_id,cvr FROM Conversion_Rates_Per_Product WHERE event_date=CURRENT_DATE() order by cvr desc limit 10;
--- 当日DAU
-SELECT EVENT_DATE,DAU FROM DAU WHERE event_date=CURRENT_DATE();
-```

-# UNDROP TABLE 语句
-
-使用 UNDROP TABLE 语句可以恢复被删除的表、动态表和物化视图。是否可以恢复被删除的对象依赖于数据的[保留周期](<TIMETRAVEL.md>)。
-**数据保留周期**：
-对象的历史恢复能力取决于数据的保留周期。当前默认保留周期为1天。您可以通过执行[ALTER命令](TIMETRAVEL.md)来调整保留周期。请注意，修改保留周期可能会增加存储成本。支持表（TABLE）和动态表（DYNAMIC TABLE）不支持物化视图
-
-## 语法
-
-```sql
-UNDROP TABLE tablename;
-```
-
-## 参数说明
-
-- **tablename**：指定被删除的表的名字。支持动态表、内部表、物化视图。
-
-## 示例
-### 示例 1：恢复动态表
-
-```sql
--- 创建一个基表
-DROP TABLE IF EXISTS dy_base_a;
-CREATE TABLE dy_base_a (i int, j int);
-INSERT INTO dy_base_a VALUES
-(1, 10),
-(2, 20),
-(3, 30),
-(4, 40);
--- 使用dynamic table进行加工
-DROP DYNAMIC TABLE IF EXISTS change_table;
-CREATE DYNAMIC TABLE change_table
-(i, j)
-AS SELECT * FROM dy_base_a;
--- 刷新dynamic table
-REFRESH DYNAMIC TABLE change_table;
--- 查询数据
-SELECT * FROM change_table;

-| 3 | 30 |
-| 4 | 40 |
-+---+----+
-DROP DYNAMIC TABLE IF EXISTS change_table;
-UNDROP TABLE change_table;
-SELECT * FROM change_table;
-```
-### 示例 2：删除表后创建同名的表恢复
-
-```sql
--- 创建表
-CREATE TABLE mytable(id int, name string);
-INSERT INTO mytable VALUES(1, 'aaa');
--- 删除表
-DROP TABLE mytable;
--- 查看表删除记录
-SHOW TABLES HISTORY;
--- 重复建表

-## 导出数据到本地
-
-本文档详细介绍了如何将表中数据下载到本地。
-
-目前 Lakehouse 支持两种下载模式：
-
-1. 使用 Lakehouse Studio 的可视化下载界面。
-2. 使用 JDBC 客户端工具，通过 GET 命令下载文件到本地。
-
-## 使用 Lakehouse Studio 的可视化下载界面
-
-在数据开发中，执行 SQL 后，可以将结果下载为 Excel 或 CSV 文件。同时，由于界面显示的结果集限制为 10000 条，如果想下载全部数据，可以点击“下载全部 CSV 文件”，如下图所示：
-
-![](.topwrite/assets/image_1714294896867.png)
-
-## 使用 GET 命令下载数据
-
-1. 前置条件
-
-   * 已安装 [命令行工具](connect-with-cli.md)。
-   * 了解 [GET命令](GET.md) 和 [COPY INTO](COPY_INTO_Location.md) 导出命令。

-        batch_size=25,
-        max_retries=3,
-        dimensions=1024
-    ),
-    "v4": DashScopeEmbeddingConfig(
-        model_name="text-embedding-v4",
-        batch_size=30,
-        max_retries=3,
-        dimensions=1024
-    )
-}
-
-# 选择合适的模型
-embed_config = configs["v4"]  # 推荐使用最新版本
-```
-
-## 最佳实践
-
-### 性能优化
-
-1. **批量处理大小**
-   * SQL 连接器：1000-5000 行/批次
-   * Volume 连接器：100-500 文件/批次
-   * DashScope 嵌入：20-30 文档/批次
-
-2. **内存管理**
-   ```python
-   # 对于大型数据集，使用流式处理
-   for batch in indexer.run():
-       processed = downloader.run(file_data=batch)
-       # 立即处理，避免内存积累
-       process_batch(processed)
-       del processed  # 显式释放内存
-   ```
-
-3. **错误处理**
-   ```python
-   import time
-   from unstructured_ingest.errors_v2 import UserAuthError, UserError
-
-   def robust_processing(files, max_retries=3):
-       for file_data in files:
-           for attempt in range(max_retries):
-               try:
-                   result = process_file(file_data)
-                   break
-               except UserAuthError:
-                   # 认证错误，不重试
-                   raise
-               except UserError as e:
-                   if attempt == max_retries - 1:
-                       raise
-                   time.sleep(2 ** attempt)  # 指数退避
-   ```
-
-### 数据质量保证
-
-1. **输入验证**
-   ```python
-   def validate_input_data(data):
-       required_fields = ['id', 'content']
-       for item in data:
-           if not all(field in item for field in required_fields):
-               raise ValueError(f"缺少必需字段: {required_fields}")
-           if not item['content'].strip():
-               raise ValueError("内容不能为空")
-   ```
-
-2. **输出验证**
-   ```python
-   def validate_embeddings(embeddings, expected_dimension):
-       for i, embedding in enumerate(embeddings):
-           if len(embedding) != expected_dimension:
-               raise ValueError(f"嵌入 {i} 维度错误: {len(embedding)} != {expected_dimension}")
-   ```
-
-### 监控和日志
-
-```python
-import logging
-from unstructured_ingest.logger import logger
-
-# 配置详细日志
-logging.getLogger("unstructured_ingest").setLevel(logging.DEBUG)
-
-# 添加性能监控
-import time
-from contextlib import contextmanager
-
-@contextmanager
-def timer(description):
-    start = time.time()
-    yield
-    elapsed = time.time() - start
-    logger.info(f"{description} 耗时: {elapsed:.2f} 秒")
-
-# 使用示例
-with timer("文档处理"):
-    processed = process_documents(documents)
-```
-
-## 故障排查
-
-### 常见问题
-
-1. **连接失败**
-   ```
-   错误: Failed to create clickzetta session
-   解决: 检查环境变量配置，确保网络连通性
-   ```
-
-2. **嵌入生成失败**
-   ```
-   错误: DashScope API key invalid
-   解决: 验证 DASHSCOPE_API_KEY 环境变量
-   ```
-
-3. **文件下载失败**
-   ```
-   错误: Volume 'xxx' 中未找到匹配的文件
-   解决: 检查 volume 名称和路径是否正确
-   ```
-
-### 调试技巧
-
-1. **启用详细日志**
-   ```python
-   import os
-   os.environ["UNSTRUCTURED_LOG_LEVEL"] = "DEBUG"
-   ```
-
-2. **测试连接**
-   ```python
-   # 测试云器 Lakehouse 连接
-   with ClickzettaConnectionConfig().get_session() as session:
-       result = session.sql("SELECT CURRENT_TIMESTAMP()").collect()
-       print("连接正常")
-
-   # 测试 DashScope
-   from unstructured_ingest.embed.dashscope import DashScopeEmbeddingConfig
-   config = DashScopeEmbeddingConfig(model_name="text-embedding-v3")
-   embeddings = config.embed_documents(["测试文本"])
-   print(f"嵌入维度: {len(embeddings[0])}")
-   ```
-
-3. **验证数据流**
-   ```python
-   # 在每个阶段输出样本数据
-   logger.info(f"索引阶段: 找到 {len(indexed_files)} 个文件")
-   logger.info(f"下载阶段: 处理 {len(downloaded_files)} 个文件")
-   logger.info(f"嵌入阶段: 生成 {len(embeddings)} 个向量")
-   ```

-### Volume 连接器使用示例
-
-#### 完整的 Volume 操作流程
-
-以下示例展示了如何正确使用修复后的 Volume 连接器：
-
-```python
-import tempfile
-from pathlib import Path
-from unstructured_ingest.processes.connectors.fsspec.clickzetta_volume import *
-
-# 1. 创建连接配置
-config = ClickzettaVolumeConnectionConfig(
-    access_config=ClickzettaVolumeAccessConfig()
-)
-
-# 2. 索引操作 - 列出文件
-indexer = ClickzettaVolumeIndexer(
-    connection_config=config,
-    index_config=ClickzettaVolumeIndexerConfig(
-        index_volume_type="user",  # 或 "table", "named"
-        index_volume_name=None,    # table/named volume 需要指定名称
-        index_remote_path="docs/", # 可选：指定子目录
-        index_regexp=r".*\.pdf$"   # 可选：正则过滤
-    )
-)
-files = indexer.list_files()
-
-# 3. 下载操作 - 智能错误处理
-with tempfile.TemporaryDirectory() as temp_dir:
-    downloader = ClickzettaVolumeDownloader(
-        connection_config=config,
-        download_config=ClickzettaVolumeDownloaderConfig(
-            download_volume_type="user",
-            download_dir=temp_dir,
-            # 其他字段会自动继承或推断
-        )
-    )
-    results = downloader.run(files[:3])  # 下载前3个文件
-
-    for result in results:
-        if result["status"] == "success":
-            print(f"下载成功: {result['local_path']}")
-        else:
-            print(f"下载失败: {result['error']}")
-
-# 4. 上传操作 - 自动构建 remote_url
-test_file = Path("test.txt")
-test_file.write_text("测试内容")
-
-uploader = ClickzettaVolumeUploader(
-    connection_config=config,
-    upload_config=ClickzettaVolumeUploaderConfig(
-        volume_type="user",
-        remote_path="uploaded_test.txt"
-        # remote_url 会自动构建
-    )
-)
-uploader.upload_file(str(test_file), "uploaded_test.txt")
-
-# 5. 删除操作 - 彻底删除验证
-deleter = ClickzettaVolumeDeleter(
-    connection_config=config,
-    deleter_config=ClickzettaVolumeDeleterConfig(
-        delete_volume_type="user"
-    )
-)
-success = deleter.delete_file("uploaded_test.txt")
-print(f"删除结果: {success}")
-
-# 6. 验证删除效果
-files_after = indexer.list_files()
-remaining = [f for f in files_after if f["name"] == "uploaded_test.txt"]
-print(f"删除后剩余文件: {len(remaining)}")  # 应该为 0
-```
-
-#### 关键改进说明
-
-1. **配置类字段完整性**: 所有配置类现在包含必要的字段
-2. **路径处理修复**: 修复了字符串和 Path 对象拼接问题
-3. **智能错误处理**: 自动检测和处理 XML 错误响应
-4. **目录vs文件修复**: 正确处理 ClickZetta 创建目录的情况
-5. **删除功能验证**: 确保删除操作的完整性和正确性

-## 使用数据上传功能上传数据
-
-您可以通过云器Lakehouse web界面上的「数据上传」功能向Lakehouse的表中添加数据。
-
-## 使用说明
-
-* 适合较小（不大于2GB）的本地文件（CSV、TXT、Parquet、Avro、ORC）直接上传到云器Lakehouse的表中，无需编程实现，方式最简单。
-* 当前仅支持一次上传一个文件
-* 数据上传功能暂不支持对文件中 struct、map、array 这三种数据类型的字段进行解析。
-
-## 使用数据上传功能
-
-使用数据上传功能时，您可以创建新表，也可以将数据上传到已有表中。
-
-### 将数据上传到新表
-
-在上传数据的时候，您通常可以同时为数据创建一个新表。
-
-#### 前提条件
-
-**您需要具备如下条件才可以使用该功能**
-
-* 您具有如下角色之一：workspace_admin、workspace_dev、workspace_analyst
-* 或者您具有如下权限点：create table、insert + update、delete + insert + update
-
-#### 操作步骤
-
-1. 登录云器Studio账号。
-
-2. 在如下地方均可以点击「上传数据」
-
-   1. 实例首页->数据上传
-   2. 开发->数据树左侧
-   3. 数据资产地图->数据上传
-   4. 数据资产地图->数据管理->数据树->数据上传
-
-      ![](.topwrite/assets/image_1736307100971.png =361)
-
-3. 可将本地文件通过拖拽，或者点击浏览本地系统上的文件的方式添加进来。一次只能添加1个文件，且大小不得超过2GB。
-
-4. Schema：选择目标schema。
-
-5. 选择表：选择「新建表」并在后方输入新建表名。
-
-6. 集群：当前schema所在的工作空间下的可用集群。
-
-7. 数据导入方式：支持追加写入，和先清空后写入两种方式导入数据至新建表中。
-
-8. 信息全部确认后点击“下一步”，系统会基于已上传的文件信息，自动解析出文件中的字段信息。
-
-   ![](.topwrite/assets/image_1736307305607.png =380)
-
-9. 检查并判断自动解析出来的字段名称和字段类型等信息是否符合预期，确认无误后，点击「确认」即可完成新建表并上传数据的操作。
-    * 若发现字段解析有问题，可通过修改**文件属性**配置项，重新刷新获取自动解析后的字段名称、字段类型等信息。或自行修改字段名称或字段类型。
-    * 注意：修改后的字段类型若与系统解析的不匹配，可能导致上传失败。
-
-### 将数据上传到已有表
-
-#### 前提条件
-
-**您需要具备如下条件才可以使用该功能**
-
-* 您具有如下角色之一：workspace_admin、workspace_dev、workspace_analyst
-* 或者您具有如下权限点：create table、insert + update、delete + insert + update
-
-#### 操作步骤
-
-1. 登录云器Studio账号。

-
-     ![](.topwrite/assets/image_1736307178433.png =353)
-
-3. 可将本地文件通过拖拽，或者点击浏览本地系统上的文件的方式添加进来。一次只能添加1个文件，且大小不得超过2GB。
-
-4. Schema：选择目标schema。
-
-5. 选择表：选择「已有的表」
-
-6. 集群：当前schema所在的工作空间下的可用集群
-
-7. 数据导入方式：支持追加写入，和先清空后写入两种方式导入数据至**已有表**中。
-
-8. 信息全部确认后点击“下一步”。
-
-   ![](.topwrite/assets/image_1736307408590.png =427)
-
-9. 对上传的文件进行相应的解析配置。
-
-   1. 文件类型：系统会基于上传文件的格式后缀自动解析出文件类型，用户也可以自行选择其他文件类型，但是需要确保选择的文件类型与上传的文件实际类型一致。
-
-   2. 文件属性配置：
-
-   3. 表头：
-
-      * 第一行为表头：从文件第一行开始解析，同时将第一行直接解析为「字段名称」并与已有表进行匹配。若有匹配不上的会被判断失败。
-      * 无表头：忽略第一行，从第二行开始作为数值进行读取。
-      * 跳过前N行：自行设置跳过的行数，并从N+1行开始作为数值进行读取。
-
-   4. 字段包裹字符：
-
-      * 双引号：在列分隔符设定下，将双引号 "" 内的内容解析为字段值。**推荐选项**。
-      * 单引号：在列分隔符设定下，将单引号 '' 内的内容解析为字段值。

-INFO:stdout_log:02:22:03    Connection test: [OK connection ok]
-
-INFO:file_log:10:22:03.153933 [info ] [MainThread]:   Connection test: [OK connection ok]
-
-02:22:03  All checks passed!
-```
-
-6. 测试运行
-
-通过 `dbt run` 将在目标 dev 环境构建 dbt 项目内置的 2 个测试模型：
-
-* model.cz\_dbt\_project.my\_first\_dbt\_model
-* model.cz\_dbt\_project.my\_second\_dbt\_model
-
-```PowerShell
-$ dbt run
-```
-
-查看执行日志是否成功，并检查目标环境下（例如 `dbt_dev` schema）是否成功创建 `my_first_dbt_model`、`my_second_dbt_model` 数据对象。
-
-# 创建基于Table Stream的增量加工任务
-
-## 场景说明
-
-首先，将外部写入的表定义为 Source Table，并为 Source Table 创建 Table Stream 对象以获取增量变化数据；
-
-其次，在 DBT 中创建使用 Table Stream 的增量模型（"materialized='incremental'"）；
-
-最后，多次运行模型观察增量处理效果。
-
-![](.topwrite/assets/image_1722603029545.png)
-
-## 准备Source表
-
-创建一张原始表，通过数据集成工具持续导入数据：
-
-```SQL
-CREATE TABLE public.ecommerce_events_multicategorystore_live(
-  `event_time` timestamp,
-  `event_type` string,
-  `product_id` string,
-  `category_id` string,
-  `category_code` string,
-  `brand` string,
-  `price` decimal(10,2),
-  `user_id` string,
-  `user_session` string)
-TBLPROPERTIES(
-  'change_tracking'='true');
-```
-
-注意需要在表属性里增加 `'change_tracking' = 'true'` 设置，以开启增量数据捕获能力。
-
-为原始表创建一个Table Stream对象，跟踪原始表的变化记录：
-
-```SQL
--- Create stream on source table
-CREATE TABLE STREAM public.stream_ecommerce_events 
-on table ecommerce_events_multicategorystore_live
-with PROPERTIES ('TABLE_STREAM_MODE' = 'APPEND_ONLY')
-```
-
-同时在 `cz_dbt_project` 的 models 目录下新建 `sources.yml` 文件，声明已创建的 2 张 source table：
-
-![](.topwrite/assets/image_1722603115937.png)
-
-## 开发模型
-
-创建名称为 events\_enriched.sql 的 dbt 模型，通过配置方式声明为增量模型：
-
-```SQL
-{{
-   config(
-       materialized='incremental'
-   )
-}}
-
-SELECT
-  event_time,
-  CAST(SUBSTRING(event_time,0,19) AS TIMESTAMP) AS event_timestamp, 
-  SUBSTRING(event_time,12,2) AS event_hour, 
-  SUBSTRING(event_time,15,2) AS event_minute, 
-  SUBSTRING(event_time,18,2) AS event_second, 
-  event_type,
-  product_id, 
-  category_id,
-  category_code,
-  brand,
-  CAST(price AS DECIMAL(10,2)) AS price, 
-  user_id, 
-  user_session,
-  CAST(SUBSTRING(event_time,0,19)AS date) AS event_date,
-  CURRENT_TIMESTAMP() as loaded_at
-FROM
-{% if is_incremental() %}
-{{source('quning', 'stream_ecommerce_events')}} 
-{% else %}
-{{source('quning', 'ecommerce_events_multicategorystore_live')}} 
-{% endif %}
-```
-
-注意：
-
-* 当通过 `dbt build` 命令构建模型时，`is_incremental()` 条件判断为 False，将使用原始表 `ecommerce_events_multicategorystore_live` 的全量数据进行模型构建；
-* 当通过 `dbt run` 执行模型时，`is_incremental()` 将识别为 True，将进行增量加工；
-
-如果您希望在构建和后续运行时都仅使用 Table Stream 的增量数据（Table Stream 默认仅提供其创建之后的变化数据）进行模型构建，可对模型进行如下定义：
-
-```Go
-{{
-   config(
-       materialized='incremental'
-   )
-}}
-
-SELECT 
-  `event_time` ,
-  `event_type` ,
-  `product_id` ,
-  `category_id` ,
-  `category_code` ,
-  `brand` ,
-  `price` ,
-  `user_id` ,
-  `user_session` ,
-  CURRENT_TIMESTAMP() as load_time
-  FROM 
-{{source('public', 'stream_ecommerce_events')}}   
-```
-
-## 构建模型
-
-通过 `dbt build` 命令在目标环境创建模型：
-
-```PowerShell
-dbt build --model events_enriched
-```
-
-通过观察日志，模型构建时通过以下语句创建模型，并初始对原始表全量数据进行加工转换：
-
-```SQL
-/* {"app": "dbt", "dbt_version": "1.5.11", "profile_name": "cz_dbt_project", "target_name": "dev", "node_id": "model.cz_dbt_project.events_enriched"} */
-create table dbt_dev.events_enriched
-as
-SELECT
-  event_time,
-  CAST(SUBSTRING(event_time,0,19) AS TIMESTAMP) AS event_timestamp, 
-  SUBSTRING(event_time,12,2) AS event_hour, 
-  SUBSTRING(event_time,15,2) AS event_minute, 
-  SUBSTRING(event_time,18,2) AS event_second, 
-  event_type,
-  product_id, 
-  category_id,
-  category_code,
-  brand,
-  CAST(price AS DECIMAL(10,2)) AS price, 
-  user_id, 
-  user_session,
-  CAST(SUBSTRING(event_time,0,19)AS date) AS event_date,
-  CURRENT_TIMESTAMP() as loaded_at
-FROM
-public.ecommerce_events_multicategorystore_live;
-```
-
-在 Lakehouse 的目标环境下检查数据对象：
-
-![](.topwrite/assets/image_1722603148172.png)
-
-```SQL
-select count(*)  from events_enriched ;
-`count`(*) 
----------- 
-3700       
-```
-
-数据对象以及初始数据成功创建并写入。
-
-## 运行模型
-
-通过 `dbt run` 命令运行模型：
-
-```PowerShell
-dbt run --model events_enriched
-```
-
-根据 dbt 增量模型逻辑，dbt 将在目标环境创建一个临时视图来表示增量数据。
-
-```SQL
-/* {"app": "dbt", "dbt_version": "1.5.11", "profile_name": "cz_dbt_project", "target_name": "dev", "node_id": "model.cz_dbt_project.events_enriched"} */
-
-create or replace view dbt_dev.events_enriched__dbt_tmp as
-SELECT
-  event_time,
-  CAST(SUBSTRING(event_time,0,19) AS TIMESTAMP) AS event_timestamp, 
-  SUBSTRING(event_time,12,2) AS event_hour, 
-  SUBSTRING(event_time,15,2) AS event_minute, 
-  SUBSTRING(event_time,18,2) AS event_second, 
-  event_type,
-  product_id, 
-  category_id,
-  category_code,
-  brand,
-  CAST(price AS DECIMAL(10,2)) AS price, 
-  user_id, 
-  user_session,
-  CAST(SUBSTRING(event_time,0,19)AS date) AS event_date,
-  CURRENT_TIMESTAMP() as loaded_at
-FROM
-public.stream_ecommerce_events;
-```
-
-同时，dbt 根据模型中 `materialized='incremental'` 的配置，使用 `MERGE INTO` 将 table stream 中的增量数据写入目标模型：
-
-```SQL
-/* {"app": "dbt", "dbt_version": "1.5.11", "profile_name": "cz_dbt_project", "target_name": "dev", "node_id": "model.cz_dbt_project.events_enriched"} */
-
-    -- back compat for old kwarg name
-merge into dbt_dev.events_enriched as DBT_INTERNAL_DEST
-      using dbt_dev.events_enriched__dbt_tmp as DBT_INTERNAL_SOURCE
-      on FALSE
-  when not matched then insert
-     (`event_time`,`event_timestamp`,`event_hour`,`event_minute`,`event_second`,`event_type`,`product_id`,`category_id`,`category_code`,`brand`,`price`,`user_id`,`user_session`,`event_date`,`loaded_at`)
-  values (
-        DBT_INTERNAL_SOURCE.`event_time`,DBT_INTERNAL_SOURCE.`event_timestamp`,DBT_INTERNAL_SOURCE.`event_hour`,DBT_INTERNAL_SOURCE.`event_minute`,DBT_INTERNAL_SOURCE.`event_second`,DBT_INTERNAL_SOURCE.`event_type`,DBT_INTERNAL_SOURCE.`product_id`,DBT_INTERNAL_SOURCE.`category_id`,DBT_INTERNAL_SOURCE.`category_code`,DBT_INTERNAL_SOURCE.`brand`,DBT_INTERNAL_SOURCE.`price`,DBT_INTERNAL_SOURCE.`user_id`,DBT_INTERNAL_SOURCE.`user_session`,DBT_INTERNAL_SOURCE.`event_date`,DBT_INTERNAL_SOURCE.`loaded_at`
-    );
-```
-
-每次执行 dbt run，都会从 table stream 中读取数据并 Merge into 目标模型。写入成功后，Table Stream 的变化记录位置会自动前进，下次 dbt run 时将自动处理最新的增量数据。
-
-# 创建基于动态表的加工任务
-
-## 场景说明
-
-结合前面的场景设计，这里继续使用dbt-clickzetta的Dynamic Table模型对已经完成转换的表进行聚合加工。
-
-首先，在 dbt 中创建使用 Dynamic Table 的模型（`materialized='dynamic_table'`），配置定义 dynamic table 的刷新周期、刷新所使用的计算资源等信息，以便在模型构建后，系统能够根据调度参数自动进行刷新。
-
-其次，在目标环境观察动态表模型的构建和刷新结果。
-
-![](.topwrite/assets/image_1722603183742.png)
-
-## 开发模型
-
-创建名称为 product\_grossing.sql 的 dynamic table 模型。
-
-* 代码定义
-
-```SQL
-{{
-   config(
-       materialized = 'dynamic_table',
-       vcluster = 'default',
-       refresh_interval = '5 minute'
-   )
-}}
-
-select 
-  event_date,
-  product_id,
-  sum(price) sum_price 
-from 
-  {{ ref("events_enriched")}}
-group by event_date,product_id
-```
-
-## 构建模型
-
-通过 `dbt build` 命令在目标环境创建模型：
-
-```PowerShell
-dbt build --model product_grossing
-```
-
-通过观察日志，模型构建时通过以下语句创建模型，并初始对原始表全量数据进行加工转换：
-
-```SQL
-/* {"app": "dbt", "dbt_version": "1.5.11", "profile_name": "cz_dbt_project", "target_name": "dev", "node_id": "model.cz_dbt_project.product_grossing"} */
-create or replace dynamic table dbt_dev.product_grossing
-refresh interval 5 minute
-vcluster default
-as
-select 
-  event_date,
-  product_id,
-  sum(price) sum_price 
-from 
-  dbt_dev.events_enriched
-group by event_date,product_id;
-```
-
-通过 dbt 可查看模型血缘关系：
-
-![](.topwrite/assets/image_1722603216025.png)
-
-在 Lakehouse 的目标环境下检查数据对象：
-
-```SQL
-show tables;
-
-schema_name table_name               is_view is_materialized_view is_external is_dynamic 
------------ ------------------------ ------- -------------------- ----------- ---------- 
-dbt_dev     events_enriched          false   false                false       false      
-dbt_dev     events_enriched__dbt_tmp true    false                false       false      
-dbt_dev     my_first_dbt_model       false   false                false       false      
-dbt_dev     my_second_dbt_model      true    false                false       false      
-```
-
-同时通过 `DESC` 命令查看动态表的信息，重点确认运行集群、刷新周期参数是否符合预期：
-
-```SQL
-desc extended product_grossing;
-
-column_name                  data_type                                                                                                                                                                                                                                                     
----------------------------- ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 
-event_date                   date

-## 运行模型
-
-Dynamic Table 类型的 dbt 模型，通过构建时设置的周期刷新参数，由 Lakehouse 自动调度，无需通过 `dbt run` 命令执行。
-
-在目标环境完成模型构建后，您可以在 Lakehouse 平台通过以下 SQL 命令查看动态表的刷新状态：
-
-```SQL
-show dynamic table refresh history where name ='product_grossing'
-
-workspace_name schema_name name             virtual_cluster start_time          end_time            duration             state   refresh_trigger  suspended_reason refresh_mode error_message source_tables                                                             stats                                     completion_target job_id

-## 功能
-
-本语句用于切换当前数据库中的 schema，以便用户能够更方便地操作和管理不同 schema 下的数据表。
-
-## 语法
-
-```SQL
-USE [SCHEMA] schema_name;
-```
-
-## 参数说明
-
-1. `SCHEMA`：这是一个可选关键字，您可以使用或省略它。
-2. `schema_name`：指定要切换到的 schema 名称。
-
-## 使用示例
-
-1. 切换到名为 `ods_schema` 的 schema：
-
-   ```SQL
-   USE ods_schema;
-   ```
-
-2. 切换到名为 `reporting_schema` 的 schema，省略 `SCHEMA` 关键字：
-
-   ```SQL
-   USE reporting_schema;
-   ```
-
-3. 切换到名为 `customer_data` 的 schema，并在切换后执行一些查询操作：
-
-   ```SQL
-   USE customer_data;
-   SELECT * FROM customer_orders;
-   SELECT COUNT(*) FROM customer_orders WHERE order_status = 'completed';
-   ```
-
-## 注意事项
-
-- 当您在 SQL 语句中使用 `USE` 切换到某个 schema 后，接下来的查询操作将默认针对该 schema 下的数据表进行。
-- 如果您需要在多个 schema 之间频繁切换，可以在 SQL 语句中多次使用 `USE` 语句。
-- 在使用 `USE` 语句时，请确保指定的 schema 名称在当前数据库中存在，否则将导致错误。

-# 使用 Java SDK 读取 Kafka 数据并实时上传
-
-本文档详细介绍了如何利用 Java SDK 将数据实时写入 Lakehouse，适用于需要实时数据流处理的业务场景，特别适合熟悉 Java 的开发人员。本案例以 Kafka 为数据源，展示如何读取 Kafka 数据并通过 Lakehouse 的 RealtimeStream 接口进行写入。如果您对读取 Kafka 数据没有特殊要求，推荐使用 Lakehouse Studio 数据集成。Lakehouse Studio 数据集成提供了可视化监控，提高了数据管理的透明度。
-
-# 参考文档
-
-[Java SDK实时上传数据](java_reference/realtime-upload.md)
-
-## 应用场景
-
-* 适用于需要实时处理数据流的业务场景。
-* 适合熟悉Java并需要自定义逻辑处理的开发人员。
-
-## 使用限制
-
-* 实时写入的数据可以秒级查询。
-* 表结构变更时，需停止实时写入任务，并在变更后约 90 分钟重新启动。
-* table stream、materialized view 和 dynamic table 只能显示已经提交的数据。实时任务写入的数据需要等待约 1 分钟才能确认，因此 table stream 也需要等待约 1 分钟才能看到。
-
-# 使用案例
-
-本案例使用 Kafka 的 Java 客户端读取数据，并调用 Lakehouse 的 RealtimeStream 接口进行写入。
-
-## 环境准备
-
-* 拥有 Kafka 集群（本次演示使用的是本地搭建的 Kafka），并创建 Topic `lakehouse-stream`。
-
-  * ```SQL
-    bin/kafka-topics.sh --create --topic lakehouse-stream --bootstrap-server localhost:9092
-    ```
-
-* 数据格式为 JSON，使用 Kafka 命令行生产数据：
-
-  * ```SQL
-    {"id": 1, "name": "张三", "email": "zhangsan@example.com", "isActive": true}
-    --kafka生产者命令行
-    bin/kafka-console-producer.sh --topic lakehouse-stream --bootstrap-server localhost:9092
-    ```
-
-* 在 Lakehouse 上创建表
-
-  * ```SQL
-    create table realtime_stream(id int,event json);
-    ```
-
-## 使用Java代码开发
-
-### Maven依赖
-
-在项目的 `pom.xml` 文件中添加以下依赖。Lakehouse Maven 最新依赖可以在 [maven库](https://central.sonatype.com/artifact/com.clickzetta/clickzetta-java) 中找到。
-
-```SQL
-<dependency>
-    <groupId>com.clickzetta</groupId>
-    <artifactId>clickzetta-java</artifactId>
-    <version>1.3.1</version>
-</dependency>
-<!-- https://mvnrepository.com/artifact/org.apache.kafka/kafka-clients -->
-<dependency>
-    <groupId>org.apache.kafka</groupId>
-    <artifactId>kafka-clients</artifactId>
-    <version>3.2.0</version>
-</dependency>
-```
-
-### 编写Java代码
-
-1. **定义 Kafka 连接类**：创建一个 `KafkaReader` 类，配置 Kafka 消费者。
-2. **消费 Kafka 并写入 Lakehouse**：创建 `Kafka2Lakehouse` 类，实现从 Kafka 读取数据并通过 RealtimeStream 写入 Lakehouse 的逻辑。
-
-定义一个 Kafka 连接类，Kafka 的 Java 客户端配置可以参考 [Kafka官网](https://docs.confluent.io/kafka-clients/java/current/overview.html)。
-
-```SQL
-import org.apache.kafka.clients.consumer.ConsumerConfig;
-import org.apache.kafka.clients.consumer.KafkaConsumer;
-import java.util.Collections;
-import java.util.Properties;
-// 创建一个消费者类
-public class KafkaReader {
-    // 定义一个kafka消费者对象
-    private KafkaConsumer<String, String> consumer;
-    // 定义一个构造方法，初始化消费者的配置
-    public KafkaReader() {
-        // 创建一个Properties对象，用于存储消费者的配置信息
-        Properties props = new Properties();
-        // 指定连接的kafka集群的地址
-        props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
-        // 指定消费者所属的消费者组
-        props.put(ConsumerConfig.GROUP_ID_CONFIG, "test-group");
-        // 指定消费者的key和value的反序列化器
-        props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringDeserializer");
-        props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringDeserializer");
-        // 指定消费者的自动位移提交策略
-        props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, "true");
-        // 指定消费者的自动位移提交间隔
-        props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, "1000");
-        // 使用配置信息创建一个kafka消费者对象
-        consumer = new KafkaConsumer<>(props);
-    }
-    // 定义一个方法，用于从指定的主题中读取数据
-    public KafkaConsumer<String, String> readFromTopic(String topic) {
-        consumer.subscribe(Collections.singleton(topic));
-        return consumer;
-    }

-本文档主要介绍如何使用 Java SDK 的 BulkloadStream 批量将数据加载到 Lakehouse 中。它适合一次性大量数据导入，支持自定义数据源，提供了数据导入的灵活性。本次案例以读取本地文件为例。如果您的数据源在对象存储或 Lakehouse Studio 数据集成支持的范围内，推荐使用 COPY 命令或数据集成功能。
-
-# 参考文档
-
-[Java SDK批量上传数据](java_reference/bulkload-upload.md)
-
-## 应用场景
-
-* 适用于需要批量上传大量数据的业务场景。
-* 适合熟悉Java并需要自定义数据导入逻辑的开发人员。
-
-## 使用限制
-
-* BulkloadStream不支持主键（pk）表的写入。
-* 不适用于时间间隔小于五分钟的频繁数据上传场景。
-
-# 使用案例
-
-本案例以读取本地 CSV 文件为例，使用的数据集是 [巴西电子商务](https://www.kaggle.com/datasets/olistbr/brazilian-ecommerce?select=olist_order_items_dataset.csv) 公共数据集中的 olist_order_items_dataset 数据。若数据源位于对象存储或 Lakehouse Studio 数据集成功能支持的范围，推荐使用 COPY 命令或数据集成功能。
-
-## 前置条件
-
-* 创建表
-  * ```SQL
-    create    table bulk_order_items (
-              order_id STRING,
-              order_item_id INT,
-              product_id STRING,
-              seller_id STRING,
-              shipping_limit_date STRING,
-              price DOUBLE,
-              freight_value DOUBLE
-              );
-    ```
-
-* 对目标表具有INSERT权限。
-
-## 使用Java代码开发
-
-### Maven依赖
-
-在项目的 `pom.xml` 文件中添加 Lakehouse 的 Maven 依赖。Lakehouse Maven 依赖的最新版本可以在 [maven库](https://central.sonatype.com/artifact/com.clickzetta/clickzetta-java) 中找到。
-
-```SQL
-<dependency>
-    <groupId>com.clickzetta</groupId>
-    <artifactId>clickzetta-java</artifactId>
-    <version>1.3.1</version>
-</dependency>
-```
-
-### 编写Java代码
-
-1.  **初始化 Lakehouse 客户端和 BulkloadStream**：创建 `BulkloadFile` 类，初始化 Lakehouse 连接和 BulkloadStream 对象。
-2.  **读取本地 CSV 文件并写入 Lakehouse**：使用 Java IO 流读取本地 CSV 文件，并将数据逐行写入 Lakehouse。

-
-Lakehouse 支持 MySQL 客户端与服务端的通讯协议，因此可以使用 MySQL 驱动连接 Lakehouse。然而，Lakehouse 并未实现 MySQL 的语法和数据类型。通过 MySQL 客户端连接 Lakehouse 时，执行的 SQL 语句应使用 Lakehouse 语法，而非 MySQL 语法。例如，`mysqldump` 命令在 Lakehouse 中不可用。
-
-为了适配一些 BI 报表，Lakehouse 实现了一些 MySQL 常用函数，如 `str_to_date` 和 `date_format`。目前，Lakehouse 支持的协议如下：
-MySQL8.x版本客户端连接服务端时默认使用的是caching\_sha2\_password认证方式，有关 MySQL 认证方式的更多信息请参考[官方文档](https://dev.mysql.com/doc/refman/8.0/en/authentication-plugins.html)。连接方式如下，例如连接上海阿里云：
-
-```
-jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com/public
---添加端口,可选
-jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com:3306/public
---使用ssl可选
-jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com/public?useSSL=true
-```
-
-MySQL5.x版本客户端连接服务端时默认使用的是mysql\_native\_password认证方式，有关 MySQL 认证方式的更多信息请参考[官方文档](https://dev.mysql.com/doc/refman/8.0/en/authentication-plugins.html)，连接Lakehouse是无需开启SSL，连接方式如下，例如连接上海阿里云：。
-
-* 目前需要重置密码，即使是新建的账号也需要重置密码。这是因为 MySQL 5.x 版本使用的是 `mysql_native_password` 密钥，而 Lakehouse 需要保存 MySQL 的加密算法。目前，只有在修改密码时，Lakehouse 才会保存 MySQL 密钥的加密算法。您可以在修改密码时保持和之前一样，这样可以避免影响其他任务的连接。
-
-```
-jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com/public?useSSL=false
---添加端口,可选
-jdbc:mysql://cn-shanghai-alicloud-mysql.api.clickzetta.com:3306/public?useSSL=false
-```
-
-端口：3306（可选）
-
-# 使用场景
-
-* 无法使用Lakehouse驱动场景，比如某些报表场景不支持自定义jdbc驱动或者不支持Lakehoue原生jdbc驱动。如果可以，请尽可能使用 Lakehouse 原生驱动。
-
-# 使用限制
-
-* 目前无法完全兼容MySQL函数和语法，某些报表使用的一些 MySQL 专有语法和函数在发送到 Lakehouse 时会报错（请联系 Lakehouse 支持）。
-* 数据类型限制
-  * 在使用 Lakehouse MySQL 协议时，若 SQL 语句中包含 MySQL 特有的类型（如 mediumint、numeric、bit、time、year、datetime、varbinary、text、blob、enum、set、空间数据类型），系统会报错。例如，“create table mysql\_table(col numeric)” 的建表语句，或 “select cast(xxxx as text)” 这类语句，只要 SQL 中含有上述类型，都会触发报错。为避免此问题，可使用 Lakehouse 的类型替换 MySQL 的数据类型。
-* 语法限制
-  * 不支持MySQL特有语法如MySQL dump命令、Load等命令。
-* 函数限制
-  * Lakehouse 实现了一些 MySQL 常用函数。如果您有需要请联系Lakehouse支持
-* 数据导入限制
-  * 不支持 MySQL 批量导入数据，例如 MySQL 的 LOAD 命令。
-  * 使用MySQL驱动不支持Lakehouse本地命令（[PUT](PUT.md)、[REMOVE](remove-volume.md)、[GET](GET.md)等命令），不支持使用MySQL驱动调用Lakehouse的批量上传和实时上传数据的Java SDK。
-* MySQL列出表结构时需要查询information schema，目前Lakehouse对于新建的表在information schema会存在15分钟延迟，所以新建的表无法立即看到
-
-# 连接方式
-
-## 1.设置计算集群
-
-由于 MySQL 协议中没有传入设置集群的方式，用户可以使用 SQL 命令为用户添加一个默认计算集群。这样在 MySQL 连接时就会使用该集群。需要注意的是，BI场景对分析性能往往有要求，建议为BI工具连接用户选择合适规格的分析型计算集群以提供最佳的查询性能。
-
-```sql
-ALTER USER user_name SET DEFAULT_VCLUSTER = default;
-
--- 查看集群设置是否生效
-SHOW USERS;
-```
-
-## 2.设置用户名密码
-
-由于 MySQL 协议中没有 workspace 名称和 instance 名称，因此需要将 instance 名称和 workspace 名称拼接到用户名中。
-
-用户名格式要求如下：
-
-```
-登录的账号名称@instance_name.workspace_name
-```
-
-* **instance\_name 获取**：在 [工作空间](workspace-introduction.md)页面 中获取 JDBC 连接串。例如，在 `jdbc:clickzetta://jnsxwfyr.api.clickzetta.com/quick_start?virtualCluster=default` 中，`jnsxwfyr` 为 instance\_name。
-* **workspace\_name 获取**：工作空间的名称。
-
-示例：
-
-```
-user@jnsxwfyr.quick_start
-```
-
-## 3.设置连接地址：
-
-端口：3306
-
-| 云服务商 | 地域 | 连接地址                                               |
-| ---- | -- | -------------------------------------------------- |
-| 阿里云  | 上海 | cn-shanghai-alicloud-mysql.api.clickzetta.com      |
-| 腾讯云  | 上海 | ap-shanghai-tencentcloud-mysql.api.clickzetta.com  |
-|      | 北京 | ap-beijing-tencentcloud-mysql.api.clickzetta.com   |
-|      | 广州 | ap-guangzhou-tencentcloud-mysql.api.clickzetta.com |
-| 亚马逊  | 北京 | cn-north-1-aws-mysql.api.clickzetta.com            |
-
-## 4.其他参数：
-
-* useSSL=true：Lakehouse对于mysql 8.x版本客户端时使用caching\_sha2\_password，因此使用mysql 8.x版本驱动连接时必须设置useSSL=true。如果使用的是mysql5.x版本则useSSL=false即可
-* 数据库名称: Lakehouse的schema名称
-* 端口：3306（可选）
-
-# 一般BI报表配置参数
-
-**连接工具**
-
-建议mysql java 8.0驱动，运行SQL，但是某些报表可能初始化会发一些mysql特有的语法，如果遇到报错请联系Lakehouse技术支持。
-
-**设置vcluster**:
-需要给连接的用户指定默认vcluster，在Lakehouse中指定用户默认vcluster,这样在 MySQL 连接时就会使用该集群。需要注意的是，BI场景对分析性能往往有要求，建议为BI工具连接用户选择合适规格的分析型计算集群以提供最佳的查询性能。
-
-```SQL
-ALTER USER user_name SET DEFAULT_VCLUSTER= default_ap;
---查看vcluster设置是否生效
-show users;
-```
-
-**驱动要求**：建议mysql8.0以上
-
-**连接地址（必须配置**）
-
-**用户名格式（必须配置**）
-
-* 格式：用户名@instance\_name.worksapace\_name，比如test\@jnsxwfyr.ql\_ws
-
-**数据库名称（必须配置**）
-
-* 格式：schema名称，如public
-
-**端口：3306。某些报表需要配置**
-
-**额外参数（必须配置**）：
-
-如果使用 8.x 驱动，某些报表可以直接在配置参数中输入下面字符串：
-
-* useSSL=true
-
-如果报表中不支持填写参数
-
-* 在报表界面，通常可以找到是否使用 SSL 的选项，需要勾选上。
-  如果使用的是 5.x 版本驱动，则不需要勾选。
-
-# 常见问题
-
-* 无法指定计算资源
-
-  * 需要给连接的用户指定默认vcluster，在Lakehouse中指定用户默认vcluster
-  * ```SQL
-    alter user UAT_TEST set DEFAULT_VCLUSTER= default;
-    --查看vcluster设置是否生效
-    show users;
-    ```
-
-# 问题排查
-
-通过lakehouse作业历史排查问题。如果mysql协议连通之后，mysql连接Lakehouse通常会发一些SQL，作业历史会记录发送的SQL，此时我们可以通过作业历史查看发送的SQL来看错误信息。通过筛选来快速定位，如下三个筛选条件
-
-* 计算集群：bi报表中指定的计算集群
-* 提交人：bi报表中连接的用户名比如是<<<test@jnsxwfyr.ql_ws>>>，则这里筛选为test
-* schema：bi报表中指定的schema名称
-* 通过点击右上角的刷新按钮，来监控 BI 报表发送的 SQL。
-

-
-# 案例
-
-* 使用mysql client 连接
-
-mysql client连接Lakehouse：
-
-```
--- 添加-A选项避免mysql连接时发送一些校验的SQL
-mysql -h cn-shanghai-alicloud-mysql.api.clickzetta.com -u user_name@instance_name.worksapace_name -D  public -p -A
-
---使用mysql客户端连接报错信息为：ERROR 2059 (HY000): Authentication plugin 'mysql_clear_password' cannot be loaded: plugin not enabled时。可以添加参数使用以下命令来连接
-mysql -h cn-shanghai-alicloud-mysql.api.clickzetta.com -u user_name@instance_name.worksapace_name -Dpublic -p -A --enable-cleartext-plugin  --default-auth=mysql_native_password
-
-
-
-```
-
-* 使用[Power BI连接Lakehouse](PowerBI.md)

-# USE 语句
-
-指定用于当前会话的 SCHEMA 和计算资源。
-
-
-## 语法
-
-```SQL
--- 切换 schema
-USE [SCHEMA] schema_name;
--- 切换计算资源
-USE VCLUSTER vc_name;
-```
-
-## 参数说明
-
-1. `SCHEMA`：这是一个可选关键字，可以在语句中省略。
-2. `schema_name`：指定要切换的 schema 名称。
-
-## 使用示例
-
-1. 切换到名为 `ods_schema` 的 schema：
-
-   ```SQL
-   USE ods_schema;
-   -- 查询当前的 SCHEMA
-   SELECT CURRENT_SCHEMA();
-   ```
-
-2. 假设当前工作空间中存在名为 `sample_vc` 的计算集群，您可以使用以下命令切换到该计算集群：
-
-   ```SQL
-   USE VCLUSTER sample_vc;
-   -- 查询当前的计算资源
-   SELECT CURRENT_VCLUSTER();
-   ```
-
-3. 如果您想要切换到名为 `high_performance_vc` 的计算集群，您可以执行以下命令：
-
-   ```SQL
-   USE VCLUSTER high_performance_vc;
-   ```
-
-## 使用注意事项
-
-- 在使用客户端工具（如 [客户端 SQLLine](<connect-with-cli.md>)、[DBeaver](<eco_integration/dbeaver-lakehouse.md>) 等）连接时，相关操作会在整个会话期间生效。
-- 如果您使用 Lakehouse Studio 界面，建议优先通过页面来切换 schema 和计算集群。如果直接使用命令切换，其效果仅临时生效，且需要和要执行的 SQL 语句一起选中执行方可生效。

-# USE 语句
-
-指定用于当前会话的计算资源。
-
-
-## 语法
-
-```SQL
---切换计算资源
-USE VCLUSTER vc_name;
-```
-
-## 参数说明
-
-1. `VCLUSTER`：必填关键字。
-2. `vc_name`：指定要切换的计算资源的名称。
-
-## 使用示例
-
-1. 假设当前工作空间中存在名为sample_vc的计算集群，您可以使用以下命令切换到该计算集群：
-
-   ```SQL
-   USE VCLUSTER sample_vc;
-    --查询当前的计算资源
-    SELECT CURRENT_VCLUSTER();
-   ```
-
-2. 如果您想要切换到名为high_performance_vc的计算集群，您可以执行以下命令：
-
-   ```SQL
-   USE VCLUSTER high_performance_vc;
-   ```
-
-
-## 注意事项
-- 在使用客户端工具（如[客户端SQLLine](<connect-with-cli.md>)、[DBeaver](<eco_integration/dbeaver-lakehouse.md>)等）连接时，相关操作会在整个会话期间生效。而如果您使用 Lakehouse Studio 界面，建议优先通过页面来切换 Schema 和计算集群。需要说明的是，若直接使用相关命令，其效果仅临时生效，且需要和要执行的 SQL 语句一起选中执行方可生效。

-# 用户身份
-
-云器采用了灵活的用户及身份管理体系，允许对不同层级、不同类型的用户进行区分和权限控制。
-
-本帮助文档将详细介绍：
-
-* 用户层级：包括全局账号用户和服务实例内用户。
-* 用户类型：包括普通用户和服务用户。
-
-***
-
-## 用户层级
-
-云器中的用户可根据其作用范围划分为两个层级：**全局账号用户** 和 **Lakehouse服务实例内用户**。这两种层级帮助企业在多云多区域的服务实例环境下，既能够全局管理账号下的所有用户，又能够根据服务实例区分不同用户的权限范围。
-
-:-: ![](.topwrite/assets/用户层级.png =740)
-
-^
-
-### 全局用户
-
-全局用户是在云器平台上进行全局管理和配置的用户。每个用户是系统内的一个独立身份，具备独立的用户名和密码。在一个账户中，用户名（user_name）必须唯一，用以区分不同的用户身份。不同用户之间的手机号、邮箱等信息可以重复。
-
-:-: ![](.topwrite/assets/image_1735044530952.png =800)
-
-^
-
-### 服务实例用户
-
-服务实例内用户是在具体的服务实例（instance）范围内的用户。用户只有在服务实例内，才可被授予该服务实例内的各类角色和权限。全局用户会被自动同步至各服务实例，成为服务实例用户。因此服务实例用户的创建、删除和启用状态的管理也都在全局的“用户管理”页面进行。服务实例内的“用户”列表仅提供用户信息查询功能。
-
-服务实例用户默认被授予“instance_user”角色，无任何数据和功能权限。需要进一步被授予实例或工作空间内的权限才可以进行操作。
-
-:-: ![](.topwrite/assets/image_1735044611663.png =800)
-
-***
-
-## 用户类型
-
-Lakehouse 中的用户类型主要分为 **普通用户** 和 **服务用户**：
-
-普通用户通常代表一个企业内的实际人员，在系统中进行日常的数据查询、分析、管理等操作；
-
-服务用户是为了满足自动化流程或系统级操作需求而创建的特殊类型用户。服务用户**不允许**在Web端登录，但可使用JDBC连接或被配置于调度任务中，用于调度任务、程序对Lakehouse进行自动化或系统级的调用。
-
-在Lakehouse中，服务用户包含**系统服务用户** 和 **自定义服务用户**：
-
-其中，**系统服务用户**是Lakehouse在账户初始化时默认创建的，用于访问服务实例内的资源以实现部分系统功能的用户身份；
-
-**自定义服务用户**是用户可自助创建的，用于用户自身业务应用使用的身份。
-
-Lakehouse内的系统服务用户默认为禁用状态。仅当用户使用的功能涉及系统服务用户时，系统才会提示用户“启用”，包括：
-
-sysservice_clickzetta —— 在SYS工作空间中操作临时系统资源和系统数据。
-
-sysservice_auto_mv —— 启用auto_mv时开启，用于读取job_history并管理auto_mv使用的临时mv。

-# Lakehouse用户授权入门指导
-
-## 1. 引言
-
-云器Lakehouse采用了灵活且强大的权限管理体系，通过基于角色的访问控制（RBAC）实现细粒度的数据访问管理。本指南将结合理论知识和实际操作，详细介绍Lakehouse的用户授权管理流程，帮助管理员高效管理数据资源访问权限。
-
-本指南也通过一个实际实验来验证这个过程。
-

-

-
-^
-
-## 2. 用户管理体系架构
-
-### 2.1 用户层级关系
-
-云器Lakehouse的用户管理体系分为两个层级：
-
-* **全局用户**：在云器平台上全局管理的用户，每个用户拥有独立的身份，具备唯一用户名和密码。
-* **工作空间用户**：在特定Lakehouse服务实例中的特定工作空间里的用户，仅在工作空间内内可被授予相应角色和权限。
-
-> **重要概念**：全局用户会自动同步至各服务实例，成为服务实例用户，为所有空间供应用户身份，但是需要进一步在空间内授权。因此，当我们在工作空间内通过SQL创建用户时，本质上是将已存在于服务实例中的用户添加到当前工作空间，是一种工作空间级别的授权操作，而非真正意义上的用户创建。这就是为什么在工作空间内使用SQL创建用户时不需要指定密码。
-
-### 2.2 用户类型
-
-* **普通用户**：代表企业内实际人员，用于日常的数据查询、分析和管理操作。
-* **服务用户**：满足自动化流程或系统级别操作的特殊用户，不允许Web登录，但可用于JDBC连接或调度任务。
-
-## 3. 角色管理基础
-
-### 3.1 角色定义与类型
-
-角色是一种授权管理工具，将多个权限点集中在一起，再授予给一个或多个用户。Lakehouse中的角色分为两种类型：
-
-* **预置角色**：系统自动配置的角色，不可删除，可以修改权限\*，可直接授予给用户。
-* **自定义角色**：用户根据业务需求创建的角色，可灵活配置与维护权限。
-
-\*说明：预置角色中，工作空间管理员（workspace\_admin）和实例管理员（instance\_admin）不允许修改权限。其他预置角色可以修改权限。
-
-### 3.2 角色级别
-
-* **实例角色（Instance Role**）：用于实例级资源和操作的全局管控，或跨多个工作空间的权限授予。
-* **工作空间角色（Workspace Role**）：作用于特定工作空间内的对象，如schema、table、virtual cluster等。
-
-## 4. 实际操作步骤
-
-### 4.1 用户管理操作
-
-**1. 在工作空间中添加用户**
-
-```sql
--- 将已存在于服务实例的用户添加到当前工作空间
-CREATE USER username;
-```
-
-**2. 查看工作空间内的用户**
-
-```sql
--- 显示当前工作空间内的所有用户
-SHOW USERS;
-```
-
-**3. 删除工作空间内的用户**
-
-```sql
--- 从当前工作空间移除用户（不影响服务实例中的用户）
-DROP USER username;
-```
-
-### 4.2 角色管理操作
-
-**1. 创建自定义角色**
-
-```sql
--- 创建工作空间级别的自定义角色
-CREATE ROLE role_name;
-```
-
-**2**. **查看角色**
-
-```sql
--- 查看当前工作空间内的所有角色
-SHOW ROLES;
-```
-
-**3. 删除角色**
-
-```sql
--- 删除自定义角色
-DROP ROLE role_name;
-```
-
-### 4.3 权限授予操作
-
-**1. 授予Schema级别权限**
-
-```sql
--- 授予角色在Schema上创建表和视图的权限
-GRANT CREATE TABLE, CREATE VIEW ON SCHEMA schema_name TO ROLE role_name;
-```
-
-**2. 授予表级别权限**
-
-```sql
--- 授予角色对表的查询、修改等权限
-GRANT SELECT, INSERT, UPDATE, DELETE, ALTER ON TABLE schema_name.table_name TO ROLE role_name;
-```
-
-**3. 授予视图权限**
-
-```sql
--- 授予角色对视图的查询权限
-GRANT SELECT VIEW schema_name.view_name TO ROLE role_name;
-```
-
-**4. 将角色授予用户**
-
-```sql
--- 将角色授予给用户
-GRANT ROLE role_name TO USER username;
-```
-
-### 4.4 权限撤销操作
-
-**1. 撤销对象权限**
-
-```sql
--- 撤销表的SELECT权限
-REVOKE SELECT ON TABLE schema_name.table_name FROM ROLE role_name;
-```
-
-**2. 撤销用户角色**
-
-```sql
--- 从用户撤销角色
-REVOKE ROLE role_name FROM USER username;
-```
-
-## 5. 权限验证与审计
-
-### 5.1 查询用户权限
-
-```sql
--- 查看用户被授予的角色和权限
-SHOW GRANTS TO USER username;
-```
-
-### 5.2 查询角色权限
-
-```sql
--- 查看角色被授予的具体权限
-SHOW GRANTS TO ROLE role_name;
-```
-
-### 5.3 查询对象权限被授出的权限
-
-```sql
--- 查看表被授出的具体权限及授出给哪个角色/用户
-SHOW GRANTS ON table schema_name.table_name;
-```
-
-### 5.3 查询当前用户
-
-```sql
--- 获取当前登录用户
-SELECT CURRENT_USER();
-```
-
-##
-
-## 6. 完整实验案例
-
-以下是一个完整的用户授权管理实践案例，从创建用户到清理环境的全流程：
-
-### 6.1 创建测试用户
-
-```sql
--- 创建测试用户（将服务实例用户添加到工作空间）
-CREATE USER test01;
-CREATE USER test02;
-
--- 验证用户创建是否成功
-SHOW USERS;
-```
-
-### 6.2 创建测试环境
-
-```sql
--- 创建测试Schema和表
-CREATE SCHEMA IF NOT EXISTS permission_test_schema;
-
-CREATE TABLE IF NOT EXISTS permission_test_schema.permission_test_sales_data (
-    id INT,
-    product_name VARCHAR(100),
-    sale_date DATE,
-    amount DECIMAL(10,2)
-);
-
--- 插入测试数据
-INSERT INTO permission_test_schema.permission_test_sales_data VALUES 
-    (1, 'Product A', date '2025-01-15', 1500.00),
-    (2, 'Product B', date '2025-01-20', 2300.50),
-    (3, 'Product C', date '2025-02-05', 800.75);
-```
-
-### 6.3 创建和授权角色
-
-```sql
--- 创建角色
-CREATE ROLE permission_test_developer_role;
-CREATE ROLE permission_test_analyst_role;
-
--- 配置角色权限
--- 授予开发者角色更多权限
-GRANT CREATE TABLE, CREATE VIEW ON SCHEMA permission_test_schema TO ROLE permission_test_developer_role;
-GRANT SELECT, INSERT, UPDATE, DELETE, ALTER ON TABLE permission_test_schema.permission_test_sales_data TO ROLE permission_test_developer_role;
-
--- 授予分析师角色只读权限
-GRANT SELECT ON TABLE permission_test_schema.permission_test_sales_data TO ROLE permission_test_analyst_role;
-
--- 将角色授予用户
-GRANT ROLE permission_test_developer_role TO USER test01;
-GRANT ROLE permission_test_analyst_role TO USER test02;
-```
-
-### 6.4 验证权限配置
-
-```sql
--- 查看用户权限
-SHOW GRANTS TO USER test01;
-SHOW GRANTS TO USER test02;
-
--- 查看角色权限
-SHOW GRANTS TO ROLE permission_test_developer_role;
-SHOW GRANTS TO ROLE permission_test_analyst_role;
-```
-
-### 6.5 环境清理
-
-```sql
--- 撤销角色权限
-REVOKE ROLE permission_test_developer_role FROM USER test01;
-REVOKE ROLE permission_test_analyst_role FROM USER test02;
-
--- 删除视图和表
-DROP VIEW IF EXISTS permission_test_schema.permission_test_sales_view;
-DROP TABLE IF EXISTS permission_test_schema.permission_test_sales_data;
-
--- 删除角色
-DROP ROLE permission_test_developer_role;
-DROP ROLE permission_test_analyst_role;
-
--- 删除Schema
-DROP SCHEMA IF EXISTS permission_test_schema;
-
--- 移除用户
-DROP USER test01;
-DROP USER test02;
-
--- 验证用户是否已移除
-SHOW USERS;
-```
-
-## 7. 最佳实践与注意事项
-
-### 7.1 用户管理最佳实践
-
-* **理解用户层级**：区分全局账号用户和服务实例用户，明确`CREATE USER`在工作空间中的实际作用。
-* **用户创建前检查**：使用`SHOW USERS`确认用户是否已存在于工作空间中，避免冗余操作。
-* **服务用户规范命名**：对于自动化流程的服务用户，建议以特定前缀命名，如`svc_`，以便区分。
-
-### 7.2 角色管理最佳实践
-
-* **遵循最小权限原则**：角色权限设计应遵循最小权限原则，只授予必要的权限。
-* **角色层次设计**：设计层次化的角色结构，便于权限管理和维护。
-* **角色命名规范**：采用规范的命名约定，如`[业务域]_[功能]_role`格式。
-
-### 7.3 权限审计与维护
-
-* **定期审计**：定期审查用户权限和角色分配，确保符合安全要求。
-* **权限变更记录**：记录重要的权限变更操作，便于追溯。
-* **测试验证**：权限变更后，使用相关用户身份测试验证权限是否正确生效。
-
-## 8. 常见问题与解答
-
-**Q1: 为什么在工作空间中创建用户时不需要指定密码**？
-
-A1: 这是因为`CREATE USER`命令在工作空间中执行时，实际上是将已存在于服务实例中的用户添加到当前工作空间，是一种授权操作，而非真正创建新用户。用户的身份验证信息（如密码）是在全局账号层面管理的。
-
-**Q2: 用户在一个工作空间被删除后，是否影响其在其他工作空间的访问**？
-
-A2: 不影响。`DROP USER`命令只是将用户从当前工作空间移除，不影响用户在其他工作空间的权限和访问，也不会删除服务实例中的用户信息。
-
-**Q3: 如何查看某个具体对象（如表）的所有授权情况**？
-
-A3: 通过show grants on <对象名称>的语句查看。也可以通过查询information schema查看。
-
-**Q4: 预置角色和自定义角色有什么区别**？
-
-A4: 预置角色是系统自动配置的，不可删除，适合常见场景；自定义角色由用户创建，可灵活配置权限，适合特定业务需求。
-
-**Q5: 一个用户可以同时拥有多个角色吗**？
-
-A5: 可以。用户可以被授予多个角色，将获得这些角色的所有权限的并集。
-
-## 9. 总结

-# 使用 ClickZetta MCP + Claude 进行数据运维问题排查
-
-## 问题背景
-
-某天下午，突然收到短信告警：**周期调度的数据更新任务失败**。
-
-作为值班 DBA，立即登录 ClickZetta Lakehouse，初步排查后发现：
-
-* 物化视图 `daily_summary_mv` 从当天 10 点后没有新数据；
-* 手动 刷新该物化视图可以刷新成功，但数据并没有更新；
-* 上游源表确认有最新数据。
-
-问题很棘手：源表有数据，MV 却刷不出来，而这个 MV 的 SQL 定义超过 200 行，涉及多个 CTE 和复杂的 JOIN 逻辑。
-
-**传统做法**：逐行阅读 MV 定义 → 手写诊断 SQL → 逐层排查 → 可能花费数小时。
-
-**MCP + Claude 做法**：描述问题，使用 ClickZetta MCP + Claude 帮助分析，数分钟后即得到了准确的问题根因，并进一步获得了修复建议。
-

-帮我分析以下问题的原因：
-
-我收到系统监控报警，report_schema.daily_summary_mv 从 12 月 13 日下午开始没有数据。
-
-我执行 SELECT bill_hour, COUNT(1) FROM report_schema.daily_summary_mv 
-WHERE bill_date = '20251213' GROUP BY bill_hour; 
-发现从 10 点以后就没有数据了。
-
-但是源表 raw_schema.event_details 是有数据的。
-
-执行 REFRESH MATERIALIZED VIEW 刷新后，仍没有 10 点以后的数据。
-
-查询并分析造成这一问题的原因。
-```
-
-> 💡 **提问技巧**：描述问题时包含以下要素效果最佳，描述得越具体、准确，越能提高排查效率且避免模型产生幻觉：
->
-> * 📌 **现象**：什么数据没有了
-> * 📌 **时间点**：从什么时候开始
-> * 📌 **已尝试的操作**：做过什么排查
-> * 📌 **矛盾点**：源表有数据但 MV 没有
-
-### 🤖 Claude 自动诊断过程
-
-Claude 收到问题后，自动规划并执行了以下诊断步骤：
-
-***
-
-#### 诊断步骤 1：获取 MV 定义，理解数据逻辑
-
-```sql
--- Claude 自动执行
-DESC TABLE EXTENDED report_schema.daily_summary_mv
-```
-
-Claude 从返回的 `view_text` 中识别出关键逻辑：
-
-```
-📍 发现关键线索！
-
-物化视图中有一个 MaxDateHour 的边界控制逻辑，它取两个数据源的最小值作为边界：
-
-WITH MaxDateHour AS (
-    SELECT MIN(max_ts) AS max_ts    -- ⚠️ 取最小值！
-    FROM (
-        -- 第一路数据
-        SELECT MAX(CONCAT(ds, '-', hh)) AS max_ts
-        FROM event_details WHERE event_type = 'type_a'
-        UNION ALL
-        -- 第二路数据  
-        SELECT MAX(CONCAT(ds, '-', hh)) AS max_ts
-        FROM metrics_data
-    ) t1
-)
-```
-
-***
-
-#### 诊断步骤 2：检查边界值
-
-```sql
--- Claude 自动执行
-SELECT MIN(max_ts) AS current_boundary
-FROM (
-    SELECT MAX(CONCAT(ds, '-', hh)) AS max_ts
-    FROM raw_schema.event_details WHERE event_type = 'type_a'
-    UNION ALL
-    SELECT MAX(CONCAT(ds, '-', hh)) AS max_ts
-    FROM raw_schema.metrics_data
-) t1
-```
-
-**结果**：
-
-```
-| current_boundary |
-|------------------|
-| 20251213-10      |

-
-```
-✅ 找到问题了！MaxDateHour 边界是 20251213-10，正好对应数据截止时间。
-```

-
-#### 诊断步骤 3：定位是哪个数据源落后
-
-```sql
--- Claude 自动执行：分别检查两个数据源
-SELECT 'source_a (type_a only)' AS source, MAX(CONCAT(ds, '-', hh)) AS max_ts
-FROM raw_schema.event_details WHERE event_type = 'type_a'
-UNION ALL
-SELECT 'source_a (all types)' AS source, MAX(CONCAT(ds, '-', hh)) AS max_ts
-FROM raw_schema.event_details WHERE event_type IN ('type_a', 'type_b', 'type_c')
-UNION ALL
-SELECT 'source_b' AS source, MAX(CONCAT(ds, '-', hh)) AS max_ts
-FROM raw_schema.metrics_data
-ORDER BY source
-```
-
-**结果**：
-
-```
-| source                  | max_ts       |
-|-------------------------|--------------|
-| source_a (type_a only)  | 20251213-10  |  ⬅️ 瓶颈在这里！
-| source_a (all types)    | 20251213-18  |
-| source_b                | 20251213-16  |
-```
-
-***
-
-#### 诊断步骤 4：确认数据特征
-
-```sql
--- Claude 自动执行：查看各类型的数据分布
-SELECT event_type, MAX(hh) as max_hour, COUNT(1) as record_count
-FROM raw_schema.event_details 
-WHERE ds = '20251213' AND event_type IN ('type_a', 'type_b', 'type_c')
-GROUP BY event_type
-ORDER BY event_type
-```
-
-**结果**：
-
-```
-| event_type | max_hour | record_count |
-|------------|----------|--------------|
-| type_a     | 10       | 300          |  ⬅️ 事件驱动，数据稀疏
-| type_b     | 18       | 7,070        |
-| type_c     | 18       | 22,215       |
-```

-### 🤖 Claude 输出：根因分析报告
-
-Claude通过实际在Lakehouse中执行查询和对返回数据的分析，很快得到了问题根因：
-
-MV 定义中使用 MIN() 取多个数据源的最小边界值。
-type\_a 是事件驱动型数据，只有用户执行特定操作时才产生记录。
-12月13日10点后没有相关操作，导致该类型数据"停滞"，卡住了整个 MV。
-
-以下是Claude的完整回复：

-🔍 问题根因分析报告
-
-问题定位
-物化视图的数据被 MaxDateHour 边界条件限制在了 2025年12月13日10点。

-物化视图无新数据
-
-建议方案
-修改 MaxDateHour 计算逻辑，将边界条件从仅 type_a 改为包含所有相关类型...
-```
-
-***
-
-## 第三步：根据业务需求，迭代优化方案（2分钟）
-
-Claude 给出的初步方案是直接修改边界逻辑。根据经验，对已有 MV DDL 中边界条件的修改很可能在重建后影响过去的历史数据。这在要求历史数据不许变更的业务中是不可接受的。
-
-因此，在提示词中追加了以下约束，要求在满足要求的前提下提供更好的解决方案：
-
-### 👤 提示词
-
-```
-采用这种方案：修改 MaxDateHour 的计算逻辑，将边界条件从仅 type_a 改为包含所有类型。
-
-但由于这是一个 MV，改变 DDL 重新刷新后会改变所有过去的数据，造成历史数据和已处理记录不一致。
-
-所以这里的修改希望能够兼容历史数据，加上从 2025年12月13日20点之后，
-才使用新的边界计算方式。应该怎么处理？
-```
-
-> 💡 **迭代技巧**：AI 给出的初步方案可能不完全符合业务需求。业务需求的背景知识并不存在于 AI 这次对话的上下文中，所以必须由人来充分考虑，并将这种业务约束补充给 AI。在使用 AI 来协助运维和解决问题时，不能放弃思考，无脑遵循 AI 给出的建议来执行。尤其需要提供的是“为什么有这个约束”，这样更能发挥 AI 的思考、推理能力。
->
-> 通过追加约束条件，让 AI 生成更精准的方案：
->
-> * 📌 **明确约束**：不能影响历史数据
-> * 📌 **给出边界**：从什么时间点开始生效
-> * 📌 **说明原因**：为什么有这个约束
-
-### 🤖 Claude 输出：兼容性改造方案
-
-Claude 理解了业务约束后，设计了一个向后兼容的方案：

-需要修改 MaxDateHour 的逻辑，使其：

-- 2025年12月13日20点及之后：使用新的全类型边界

-
-## 第四步：根据Claude建议的方案，对线上逻辑进行修复（2分钟）
-
-在这个案例中，直接按照上述逻辑在线上环境中手动更新了MV的DDL，重建MV后，成功修复了线上问题。
-
-其实也可以直接要求 Claude 根据上述方案操作修改该 MV 进行修复，现有工具能力完全可以实现。但考虑到线上环境较为复杂，为了避免大模型幻觉造成操作失误并引发其他问题，个人对于线上数据和表的修改、写入、重建等操作，还是倾向于采用更稳妥的人工执行方式。
-
-还有一种方式是让 Claude 根据上述方案创建一个临时视图，然后自动比对两个视图的数据，验证无误后，再更新原 MV 的 DDL。这样会更加稳妥。这个案例中的问题比较直白，为了快速修复，就省去了这一步骤。

-## 功能
-
-`uuid()` 函数用于生成一个全局唯一标识符（UUID），该标识符是一个符合通行标准的、长度为 36 个字符的字符串。UUID 是一种广泛应用于分布式系统的标识方法，可以保证在不同系统、不同时间生成的 UUID 值是唯一的。
-
-## 语法
-
-```
-uuid()
-```
-
-## 返回值
-
-该函数返回一个字符串类型的 UUID，格式为 `8-4-4-4-12`，例如：`123e4567-e89b-12d3-a456-426614174000`。
-
-## 使用示例
-
-以下是一些使用 `uuid()` 函数的示例：
-
-1. 生成一个 UUID 并将其作为新记录的 ID：
-
-   ```SQL
-   INSERT INTO users (id, username, email) VALUES (uuid(), 'john_doe', 'john@example.com');
-   ```
-
-2. 在查询中使用 UUID 作为某个唯一标识：
-
-   ```SQL
-   SELECT * FROM products WHERE id = 'a1b2c3d4-5678-90ab-cdef-1234567890ab';
-   ```
-
-3. 为每个订单生成一个唯一的追踪码：
-
-   ```SQL
-   UPDATE orders SET tracking_number = uuid() WHERE status = 'pending';
-   ```
-
-4. 在创建新的日志记录时，使用 UUID 作为日志的唯一标识：
-
-   ```SQL
-   INSERT INTO logs (log_id, user_id, action, timestamp) VALUES (uuid(), 123, 'login', NOW());
-   ```
-
-## 注意事项
-
-- UUID 值的生成依赖于特定的算法，因此不同的数据库系统可能会生成不同格式的 UUID。
-- 在使用 UUID 作为数据库表的主键时，需要注意其性能影响，因为 UUID 的生成通常是随机的，可能会导致数据在存储（如索引）上分布不均。
-- UUID 虽然具有极高的唯一性，但在某些场景下，例如需要有序处理的业务逻辑中，可能不适用。

-# 计算集群缓存
-
-Lakehouse使用缓存技术来加速查询性能和效率。平台提供了三种类型的Cache来提高查询性能
-
-1.查询结果缓存(ResultCache)
-
-2.元数据缓存(MetadataCache)
-
-3.计算集群本地缓存 (Virtual Cluster Local Disk Cache)
-
-![](.topwrite/assets/image_1729739810389.png)
-
-其中:
-
-元数据缓存和查询结果缓存服务从属于服务层,可在工作空间内共享。
-
-计算集群缓存本地缓存保存在集群本地节点,仅在使用指定虚拟集群时可以使用其本地缓存。
-
-在 Lakehouse 的存算分离架构中，数据存储在对象存储上。为了应对网络请求延迟并提升分析场景的响应速度，我们采用了缓存策略。计算集群缓存将频繁访问的数据存储在本地节点，从而加速查询。
-
-计算集群缓存分为两种：
-
-1. **主动缓存**：通过命令手动将表缓存到计算集群。每次计算集群启动时，会自动加载这些预缓存的表最新写入的数据或者分区。目前仅支持 AP 型集群。适用场景如 BI 报表查询，可以显著减少查询延迟，提高数据处理速度。
-2. **被动缓存**：在首次查询时，Lakehouse 自动将读取的文件缓存到计算集群。后续包含相同表文件的查询将直接利用缓存，加速查询过程。支持 GP 型和 AP 型集群。第二次及以后的查询，如果涉及到首次缓存的表，将直接命中缓存。
-
-## 使用方式
-
-1. **主动缓存表方式**：
-
-```SQL
-ALTER VCLUSTER default SET PRELOAD_TABLES="schema1.table1,schema2.table2";
-```
-
-如果需要添加新表到缓存,需要将已添加的表都带上否则会将原来的覆盖：
-
-```SQL
-ALTER VCLUSTER default SET PRELOAD_TABLES="schema1.table1,schema2.table2,schema3.table3";
-```
-
-## **查看缓存状态**：
-当使用 `ALTER..PRELOAD_TABLES` 命令将表加载到计算集群时，SHOW PRELOAD显示的缓存状态的更新可能会存在延迟，但是实际上缓存表已经生效。通常情况下，这种延迟大约为 10 分钟。
-
-
-* 显示当前虚拟集群的预加载表/分区状态：
-
-```SQL
-SHOW PRELOAD CACHED STATUS;
-```
-
-* 显示指定虚拟集群的预加载表/分区状态：
-
-```SQL
-SHOW VCLUSTER preload_ap_vc_test PRELOAD CACHED STATUS;
-```
-
-* 通过表名过滤预加载状态信息：
-
-```SQL
-SHOW VCLUSTER preload_ap_vc_test PRELOAD CACHED STATUS WHERE table LIKE '%x_test';
-```
-
-* 显示虚拟集群的预加载缓存汇总信息：
-
-```SQL
-SHOW EXTENDED PRELOAD CACHED STATUS;
-```
-
-## 注意事项
-
-* 集群支持自动启停，当集群停止时，缓存的表将自动释放。在 AP 型集群中，重新启动时只会缓存最新写入的数据或者分区。
-* 执行缓存命令后，只有新写入的数据才会被缓存

-# 计算集群规格代码变更说明
-
-随着越来越多的客户使用云器Lakehouse的计算集群，我们发现原本以2的指数倍增长的计算集群规格，可能会造成规格间隔过大、资源浪费。因此，我们修改了计算集群的规格，现在可以以更细粒度的方式规划计算集群的规格，提高资源利用效率，降低成本。
-
-规格代码具体调整如下：
-
-## **原计算集群规格**
-
-从XS到5XLarge，规格增加一级，算力资源增加一倍，同时资源消耗也增加一倍：
-
-|         |        |                           |
-| ------- | ------ | ------------------------- |
-| **规格**  | **简称** | **每小时消耗**（**CRU**\***时**） |
-| XSMALL  | XS     | 1                         |
-| SMALL   | S      | 2                         |
-| MEDIUM  | M      | 4                         |
-| LARGE   | L      | 8                         |
-| XLARGE  | XL     | 16                        |
-| 2XLARGE | 2XL    | 32                        |
-| 3XLARGE | 3XL    | 64                        |
-| 4XLARGE | 4XL    | 128                       |
-| 5XLARGE | 5XL    | 256                       |
-
-## **新计算集群规格**
-
-每种类型的计算集群，均以CRU（Compute Resource Unit）表示其规格。不同类型的计算集群，由于其适合的任务和资源配置不同，可以指定的规格也不同。
-
-各类计算集群的规格详细说明如下：
-
-| **类型**                         | **最小规格**（**CRU**） | **最大规格**（**CRU**） | **默认值**（**CRU**） | **步长**&#xA;（规格增减的最小单位）                                                        |

-
-每个集群每小时消耗的计算资源量为其CRU规格\*1小时，即单位为CRU\*时。例如规格为3 CRU的分析型计算集群，运行1小时的资源消耗为 3CRU \* 1小时=3CRU\*时。其费用也按照计算集群所在区域的“CRU\*时”的单价计算。
-
-## **兼容性说明**
-
-### 新旧计算集群规格对应关系
-
-存量计算集群的规格会自动转换为新规格，单位时间的计算资源消耗量和费用均不会发生变化。具体的规格对应关系如下：
-
-|         |         |          |
-| ------- | ------- | -------- |
-| **原取值** | **新取值** | **适用范围** |
-| XSMALL  | 1       | 所有类型VC   |
-| SMALL   | 2       | 所有类型VC   |
-| MEDIUM  | 4       | 所有类型VC   |
-| LARGE   | 8       | 所有类型VC   |
-| XLARGE  | 16      | 所有类型VC   |
-| 2XLARGE | 32      | 所有类型VC   |
-| 3XLARGE | 64      | 所有类型VC   |
-| 4XLARGE | 128     | 所有类型VC   |
-| 5XLARGE | 256     | 所有类型VC   |
-
-### SQL新建计算集群
-
-新规格代码上线后，新建和修改计算集群的SQL语句均将暂时兼容旧的规格代码，即Vcluster\_size 参数可同时支持以数字表达或以'XSMALL、SMALL'等代码表达的计算集群规格。请尽快迁移至使用数字表达计算集群规格的方式，以避免在切换至不兼容版本后影响计算集群的正常创建。
-
-新建集群示例代码如下：
-
-```SQL
--- 创建计算集群
-CREATE VCLUSTER [IF NOT EXISTS] vc_name
-objectProperties
-[COMMENT '']
-[WITH PROPERRIES ("key"="value"  "key"="value" ...)]
---参数变更   
-objectProperties ::=
-            VCLUSTER_SIZE = NUM --0.25-256 。兼容支持 XSMALL | SMALL | MEDIUM | LARGE | XLARGE | 2XLARGE | 3XLARGE | 4XLARGE | 5XLARGE 
-```
-
-### Web端新建计算集群
-
-Web端新建和修改计算集群时，变更为输入或指定以数字表达的计算集群规格，示例如下：
-
-:-: ![](.topwrite/assets/image_1733751304880.png =420)
-
-### SQL端查询计算集群
-
-SQL端查询计算集群规格时，所有表示计算集群规格的字段（vcluster\_size, min\_vcluster\_size，max\_vcluster\_size以及current\_vcluster\_size四个字段），均转换为以数字表达的集群大小。转换规则详见上文的“新旧计算集群规格对应关系”。
-
-### Web端查询计算集群
-
-Web端计算集群的规格变更为以数字表达计算集群规格。
-
-:-: ![](.topwrite/assets/image_1733751321636.png)
-
-## 计费说明
-
-计算集群规格代码变更前后，同规格计算集群的资源消耗和每小时费用**不会变更**。仅涉及计费单位的变更：计算规格由"XS、S”等字母表达变更为 1CRU，2CRU的数字表达；计算资源消耗量单位由CRU变更为CRU\*时。
-
-变更后，估算某个集群每小时的资源消耗量和费用更加简便。
-
-无需强记“S”规格对应每小时消耗2 CRU，再乘以资源单价来估算费用。
-
-2 CRU的计算集群，每小时就消耗“2 CRU\*时”，仅需对应单价即可计算每小时费用。

-## 概述
-
-Lakehouse 支持向量类型、向量搜索函数和向量索引，通过向量搜索函数可以实现向量检索场景。
-向量数据类型是具有固定维度的数值有序集合。向量可以表示多种数据，例如从大型语言模型 (LLM) 获得的向量嵌入、图像或面部的向量嵌入、金融时间序列、空间坐标、速度、颜色等。使用向量数据类型可以更轻松地插入、加载和查询向量。
-
-Lakehouse 提供了向量类型和向量索引检索功能。现代深度学习技术可以从非结构化数据（如文本和图像）中创建向量嵌入，即结构化的数值表示形式，同时保留生成向量的几何结构中的相似性和不相似性的语义概念。Lakehouse 提供了 VECTOR 类型来存储这些转化后的向量，构建索引可以提高向量搜索性能。
-
-## Lakehouse支持的向量功能
-
-* **向量存储**：使用 `VECTOR` 类型存储向量。
-* **向量索引**：采用 HNSW（Hierarchical Navigable Small World）算法构建向量索引，以加速计算。
-* **距离计算**：支持多种函数计算向量相似度，包括 `L2_DISTANCE` 和 `COSINE_DISTANCE` 等函数。
-
-## 使用注意事项
-
-* 当前版本的向量类型不支持比较操作，因此不能用于`ORDER BY`或`GROUP BY`子句中。
-* 向量索引的性能与内存缓存、磁盘缓存直接相关，建议单独占用 VC 使用。与其他场景混合使用会相互挤占缓存，可能导致性能不如预期。
-
-## Lakehouse向量使用
-
-**创建向量**
-
-```SQL
-
-CREATE TABLE test_vector1 (
-    vec vector(float, 4),
-    id int,
-    index test_vector1_vec_idx  (vec) using vector properties (
-        "scalar.type" = "f32",
-        "distance.function" = "l2_distance"
-    )
-);
-```
-
-properties 中支持指定的参数参考 [创建向量索引文档](create-vector-index.md)
-
-**插入数据**
-
-* 使用SQL插入
-
-```SQL
-INSERT INTO test_vector1 (vec, id) VALUES
-    (vector(0.1, 0.2, 0.3, 0.4), 1),
-    (vector(0.5, 0.6, 0.7, 0.8), 2),
-    (vector(0.9, 1.0, 1.1, 1.2), 3),
-    (vector(1.3, 1.4, 1.5, 1.6), 4),
-    (vector(1.7, 1.8, 1.9, 2.0), 5),
-    (vector(2.1, 2.2, 2.3, 2.4), 6),
-    (vector(2.5, 2.6, 2.7, 2.8), 7),
-    (vector(2.9, 3.0, 3.1, 3.2), 8),
-    (vector(3.3, 3.4, 3.5, 3.6), 9),
-    (vector(3.7, 3.8, 3.9, 4.0), 10);
-```
-
-* 如果您是通过外部系统写入到 Lakehouse 中，当前 Lakehouse 不支持直接写入 vector 类型，您可以写成 array 类型，再使用 `INSERT OVERWRITE SELECT CAST(array_col AS VECTOR)` 进行转换。
-
-  * ```SQL
-    CREATE  TABLE arraytable (vec ARRAY,id int);
-    SELECT vec::VECTOR(FLOAT, 3)
-    FROM arraytable;
-    ```
-
-* 如果数据在对象存储中，您可以直接使用volume导入vector类型
-
-**向量检索**
-
-用户可通过配置参数 `cz.vector.index.search.ef` 来调整**探索因子（ef）**，该参数用于控制在查询阶段搜索图中遍历的节点数量，从而在检索性能与准确率之间实现灵活权衡。较大的 `ef` 值通常可以提高检索的准确性，但可能增加查询延迟；较小的值则能提升检索速度，但可能牺牲部分精度。
-
-```SQL
-SET cz.vector.index.search.ef=64;
-SELECT id, l2_distance(vec, vector(1,2,3,4)) AS dist FROM test_vector1 WHERE l2_distance(vec, vector(1,2,3,4)) < 4.0 ORDER BY dist LIMIT 5;
-```
-
-当需要确认向量索引是否生效时，可以使用 `\`EXPLAIN SELECT ...\`` 语法查看 TableScan 算子中是否包含 `vector_index_search_type` 字样。
-
-```SQL
-PhysicalTableSink()
-  PhysicalLocalSort_L3($10)
-    PhysicalShuffleRead()
-      PhysicalShuffleWrite_SINGLETON()
-        PhysicalLocalSort_L3($10)
-          PhysicalCalc(NVL($4292967295, L2_DISTANCE($0, [1,2,3,4])), LT(_TRY_TO_FLOAT64(#0), 3.020000), $1) as [1, 10]
-            PhysicalTableScan(test_vector1, LT(_TRY_TO_FLOAT64(NVL(@4292967295, L2_DISTANCE(#0, [1,2,3,4]))), 3.020000, expr_key=4292967295, limit=3, vector_index_search_type=ann), F4M:LT(_TRY_TO_FLOAT64(L2_DISTANCE(#0, [1,2,3,4])), 3.020000), GEN:[L2_DISTANCE(#0, [1,2,3,4]) as 4292967295], vec, id) as [0, 1, 4292967295]
-```
-
-当向量索引未生效时，会退化到暴力检索。
-
-## 与倒排索引同时使用
-
-向量索引只能解决向量检索问题，当查询带上其他字段相关的过滤条件时，会直接退化为暴力算法。为了解决这个问题，一般有两种思路。
-
-1. 先在子查询中执行向量检索，再在外层查询中执行其他字段的过滤条件。这种方案虽然查询性能快，但如果非向量字段的过滤性比较高，最终的输出结果往往少于用户的期望数据条数，甚至为空。
-
-```SQL
-SELECT id, doc, dist FROM (
-    SELECT id, doc, l2_distance(vec, vector(1,2,3,4)) as dist FROM some_table WHERE l2_distance(vec, vector(1,2,3,4)) < 1000 ORDER BY dist LIMIT 100
-) WHERE doc like '%hello%';
-```
-
-2. 在常用的非向量字段上构建倒排索引，与向量检索一同使用：
-
-```SQL
--- 建表
-CREATE TABLE test_vector1 (
-    vec vector(float, 4),
-    index test_vector1_vec_idx  (vec) using vector properties (
-        "scalar.type" = "f32",
-        "distance.function" = "l2_distance"
-    ),
-    doc string,
-    index test_vector1_doc_idx on (doc) using inverted properties ('analyzer' = 'keyword');,
-    id int
-) ;
-
--- 查询
-SET cz.sql.index.prewhere.enabled=true; -- 当前需要设置开关，后续版本会默认开启
-SELECT id, doc, l2_distance(vec, vector(1,2,3,4)) as dist FROM some_table WHERE match_regexp(doc, '.*hello.*', map('analyzer', 'keyword')) AND l2_distance(vec, vector(1,2,3,4)) < 1000 ORDER BY dist LIMIT 100
-```
-
-上述例子中，执行流程为：先根据 `match_regexp(doc, '.*hello.*', map('analyzer', 'keyword'))` 使用倒排索引过滤出命中的行，再从命中的行中执行向量检索。
-
-## 向量检索查询时支持的参数
-
-| Name                                                  | Default Value | Notes                                        |
-| ----------------------------------------------------- | ------------- | -------------------------------------------- |
-| Name                                                  | Default Value | Notes                                        |
-| ----------------------------------------------------- | ------------- | -------------------------------------------- |
-| cz.storage.parquet.vector.index.read.memory.cache     | false         | 是否使用内存缓存                                     |
-| cz.storage.parquet.vector.index.read.local.cache      | false         | 是否使用本地SSD缓存                                  |
-| cz.storage.parquet.vector.index.read.vectors.ondemand | adaptive      | 是否按需加载向量索引（比使用内存缓存稍慢）                        |
-| cz.storage.parquet.vector.index.write.parallel        | 0             | 是否开启并行写入，0表示关闭，8表示8个线程写入。注意，性能提升比例并不与线程数成正比。 |
-
-使用示例：在 SQL 查询时设置以下参数一起执行。
-
-```SQL
-SET cz.sql.index.prewhere.enabled=true; -- 当前需要设置开关，后续版本会默认开启
-SELECT id, doc, l2_distance(vec, vector(1,2,3,4)) as dist FROM some_table WHERE match_regexp(doc, '.*hello.*', map('analyzer', 'keyword')) AND l2_distance(vec, vector(1,2,3,4)) < 1000 ORDER BY dist LIMIT 100
-```
-
-## 计费
-
-* 存储资源：向量索引会创建向量索引文件，该文件与数据文件都保存在对象存储中，统一计费。

-# VECTOR
-## 语法
-
-```Plain
-vector(scalar_type, dimension)
-vector(dimension)
-```
-
-* scalar type 为向量中的元素类型，可选，默认值是float类型。支持tinyint/int/float
-* dimension：仅指定维度
-
-**示例**：
-
-```SQL
-CREATE TABLE test_vector (
-    vec1 vector(float, 512),  -- 指定元素类型为float，维度为512
-    vec2 vector(512),         -- 默认元素类型为float，维度为512
-    vec3 vector(tinyint, 128) -- 指定元素类型为tinyint，维度为128
-);
-```
-
-**创建向量**：
-
-```SQL
-SELECT vector(1, 2, 3); -- 根据提供的值自动推导元素类型，创建一个向量
-```
-
-## 使用限制
-
-* 当前版本的向量类型不支持比较操作，因此不能用于`ORDER BY`或`GROUP BY`子句中。
-
-## 向量类型转换
-
-向量类型支持与数组类型之间的转换，以及从字符串类型转换为向量类型：
-
-1. **隐式转换**：在大多数情况下，向量类型可以直接转换为数组类型，尽量保持元素类型不变。
-2. **数组转向量**：数组类型也可以转换为向量类型，但必须确保数组长度与向量维度相匹配。不匹配时，转换结果为`NULL`。
-3. **字符串转向量**：支持将符合格式`'[1, 2, 3]'`的字符串转换为向量类型（多余空格会被忽略）。
-
-
-**示例**：
-
-```SQL
--- 将向量隐式转换为数组
-SELECT array_append(vector(1,2,3), 4);
-
--- 计算两个向量之间的L2距离
-SELECT l2_distance(array(1,2,3), vector(3,2,1));
-
--- 显式将字符串转换为向量
-SELECT cast('[1,2,3,4]' as vector(4));
-```

-
-### 您可能遇到的向量数据处理场景
-
-#### 场景1：文档相似度检索系统
-
-**当前在 Hive/Spark 中的常见做法**：
-
-```sql
--- 在Hive中存储文档向量
-CREATE TABLE document_embeddings (
-    doc_id STRING,
-    title STRING, 
-    content STRING,
-    embedding ARRAY<DOUBLE>  -- 存储LLM生成的向量
-) PARTITIONED BY (dt STRING);
-
--- 相似度计算需要复杂的UDF
-CREATE FUNCTION cosine_similarity_udf(vec1 ARRAY<DOUBLE>, vec2 ARRAY<DOUBLE>) 
-RETURNS DOUBLE
-LANGUAGE PYTHON AS $
-import numpy as np
-def cosine_similarity_udf(vec1, vec2):
-    return np.dot(vec1, vec2) / (np.linalg.norm(vec1) * np.linalg.norm(vec2))
-$;
-
--- 查询需要手动维度检查和UDF调用
-SELECT doc_id, title,
-    cosine_similarity_udf(embedding, array(0.1, 0.2, 0.3, ...)) as score
-FROM document_embeddings 
-WHERE size(embedding) = 1536  -- 手动维度检查
-    AND dt >= '2024-01-01'
-ORDER BY score DESC 
-LIMIT 10;
-```
-
-**面临的技术挑战**：
-
-* **实现复杂**：需要自定义UDF实现距离计算函数
-* **无专门索引**：数组类型无法建立针对相似度的索引
-* **类型安全问题**：数组长度不固定，容易出现维度不匹配错误
-* **性能限制**：大规模向量计算时缺乏专门优化
-
-#### 场景2：推荐系统用户特征匹配
-
-**在 Spark 中的典型实现**：
-
-```python
-# Spark中的用户向量相似度计算
-from pyspark.sql.functions import *
-from pyspark.ml.linalg import Vectors
-
-# 需要自定义函数实现相似度计算
-def cosine_similarity_udf(vec1, vec2):
-    from pyspark.ml.linalg import Vectors
-    import numpy as np
-    v1 = np.array(vec1)
-    v2 = np.array(vec2)
-    return float(np.dot(v1, v2) / (np.linalg.norm(v1) * np.linalg.norm(v2)))
-
-# 注册UDF
-cosine_udf = udf(cosine_similarity_udf, DoubleType())
-
-# 查询相似用户
-similar_users = user_features.crossJoin(user_features.alias("other")) \
-    .filter(col("user_id") != col("other.user_id")) \
-    .withColumn("similarity", cosine_udf(col("features"), col("other.features"))) \
-    .filter(col("similarity") > 0.8) \
-    .orderBy(desc("similarity"))
-```
-
-**常见的技术痛点**：
-
-* **架构复杂**：向量计算与数据存储分离，增加系统复杂度
-* **开发成本**：需要实现和维护自定义的相似度计算逻辑
-* **性能瓶颈**：大规模向量计算时缺乏专门的加速机制
-* **错误处理**：缺乏对向量维度的编译时检查
-
-### 为什么需要向量数据类型
-
-基于以上场景中的技术挑战，VECTOR数据类型的设计目标是：
-
-**解决类型安全问题**：
-
-* 提供固定维度的向量类型定义
-* 编译时进行维度匹配检查
-* 避免运行时的维度不匹配错误
-
-**简化开发流程**：
-
-* 内置常用的向量距离计算函数
-* 无需编写和维护自定义UDF
-* 与标准SQL语法完全兼容
-
-**提升查询性能**：
-
-* 支持专门的向量索引
-* 针对向量计算进行优化
-* 支持高效的相似度检索

-
-## ⚡ 快速开始
-
-### 基本使用流程
-
-```sql
--- 1. 创建包含向量列的表
-CREATE TABLE document_embeddings (
-    id BIGINT,
-    content STRING,
-    embedding VECTOR(FLOAT, 1536)  -- 1536维浮点向量
-);
-
--- 2. 插入向量数据
-INSERT INTO document_embeddings VALUES 
-(1, '人工智能技术发展', vector(0.1, 0.2, 0.3, ...));  -- 需要提供完整的1536维数据
-
--- 3. 创建向量索引
-CREATE VECTOR INDEX embedding_idx ON TABLE document_embeddings(embedding) 
-PROPERTIES(
-    "distance.function" = "cosine_distance",
-    "scalar.type" = "f32"
-);
-
--- 4. 构建索引（对已有数据）
-BUILD INDEX embedding_idx ON document_embeddings;
-
--- 5. 执行相似度查询（推荐模式）
-SELECT id, content FROM document_embeddings 
-WHERE COSINE_DISTANCE(embedding, vector(0.1, 0.2, 0.3, ...)) < 0.8
-ORDER BY id LIMIT 10;
-```
-
-***
-
-## 🆚 技术对比：ARRAY vs VECTOR
-
-### 传统ARRAY实现方式
-
-```sql
--- 使用ARRAY存储向量
-CREATE TABLE docs_array (
-    content STRING,
-    embedding ARRAY<DOUBLE>
-);
-
--- 需要自定义函数实现相似度计算
-CREATE FUNCTION cosine_similarity(vec1 ARRAY<DOUBLE>, vec2 ARRAY<DOUBLE>) 
-RETURNS DOUBLE
-LANGUAGE PYTHON AS $$
-def cosine_similarity(vec1, vec2):
-    import numpy as np
-    return np.dot(vec1, vec2) / (np.linalg.norm(vec1) * np.linalg.norm(vec2))
-$$;
-
--- 查询需要函数调用，且需要手动检查维度
-SELECT doc_id, cosine_similarity(embedding, array(0.1, 0.2, ...)) as score
-FROM docs_array
-WHERE array_size(embedding) = 1536  -- 需要手动维度检查
-ORDER BY score DESC;
-```
-
-### VECTOR原生实现方式
-
-```sql
--- 使用VECTOR类型
-CREATE TABLE docs_vector (
-    content STRING,
-    embedding VECTOR(FLOAT, 1536),  -- 类型和维度明确定义
-    
-    INDEX embedding_idx (embedding) USING VECTOR PROPERTIES (
-        "distance.function" = "cosine_distance"
-    )
-);
-
--- 使用内置函数，维度自动检查
-SELECT doc_id FROM docs_vector 
-WHERE COSINE_DISTANCE(embedding, vector(0.1, 0.2, ...)) < 0.8
-ORDER BY doc_id LIMIT 10;
-```

-### 向量创建方法
-
-```sql
--- 直接创建向量
-SELECT vector(1.0, 2.0, 3.0);              -- 创建3维浮点向量
-SELECT vector(1, 2, 3);                     -- 创建3维整数向量
-
--- 从其他类型转换
-SELECT cast(array(1,2,3) as VECTOR(INT, 3));     -- 数组转向量
-SELECT cast('[1,2,3]' as VECTOR(INT, 3));        -- JSON字符串转向量
-
--- 在表定义中使用
-CREATE TABLE feature_vectors (
-    id BIGINT,
-    dense_features VECTOR(FLOAT, 128),       -- 稠密特征
-    sparse_features VECTOR(INT, 1000)        -- 稀疏特征

-## ⚠️ 重要避坑指南
-
-### 🚨 向量查询限制
-
-经过UAT环境实际测试，发现两种不同的错误模式：
-
-#### 1. 维度不匹配错误（预期行为）
-
-```sql
--- ❌ 错误示例：使用5维向量查询128维数据
-SELECT id FROM embeddings_table 
-WHERE COSINE_DISTANCE(embedding_128d, vector(0.1, 0.2, 0.3, 0.4, 0.5)) < 0.8;
-
--- 错误信息：
--- function 'COSINE_DISTANCE' cannot be resolved, 
--- expect 'vector shall have the same dimension'
-```
-
-**解决方法**：确保查询向量与表中向量维度完全一致
-
-#### 2. Generated Column内部错误（当前限制）
-
-```sql
--- ❌ 问题查询：在SELECT中返回距离计算
-SELECT id, content,
-    COSINE_DISTANCE(embedding, vector(...)) as distance
-FROM embeddings_table 
-ORDER BY distance LIMIT 10;
-
--- 可能错误：
--- Generated column 4292967295(generated_field_4292967295) is not filled for VECTOR
-```
-
-**当前可用的查询模式**：
-
-```sql
--- ✅ 推荐：WHERE子句中的向量过滤
-SELECT id, content FROM embeddings_table 
-WHERE COSINE_DISTANCE(embedding, vector(...)) < 0.8
-ORDER BY id LIMIT 10;
-
--- ✅ 可用：简单的向量函数
-SELECT COSINE_DISTANCE(embedding, embedding) as self_distance
-FROM embeddings_table;
-
--- ❌ 避免：复杂的SELECT返回距离计算并排序
-```
-
-### 🛠️ 函数使用避坑
-
-#### L2\_NORMALIZE函数类型要求
-
-```sql
--- ✅ 正确：使用浮点数向量
-SELECT L2_NORMALIZE(vector(3.0, 4.0)) as normalized;
--- 结果：[0.6, 0.8]
-
--- ❌ 错误：使用整数向量
-SELECT L2_NORMALIZE(vector(3, 4)) as normalized;
--- 可能结果：[0, 0] （精度丢失）
-```
-
-#### 索引参数规范
-
-```sql
--- ✅ 正确：使用完整参数名
-CREATE VECTOR INDEX idx ON TABLE t(col) PROPERTIES(
-    "distance.function" = "cosine_distance",  -- 完整函数名
-    "scalar.type" = "f32"                    -- 标准类型名
-);
-
--- ❌ 错误：使用简化名称
-CREATE VECTOR INDEX idx ON TABLE t(col) PROPERTIES(
-    "distance.function" = "cosine",          -- 会报错
-    "scalar.type" = "float"                  -- 会报错
-);
-```
-
-### 🎯 最佳实践建议
-
-#### 查询模式选择
-
-| 使用场景    | 推荐模式                                     | 避免模式                            |
-| ------- | ---------------------------------------- | ------------------------------- |
-| 相似度过滤   | `WHERE COSINE_DISTANCE(...) < threshold` | `ORDER BY COSINE_DISTANCE(...)` |
-| Top-K检索 | WHERE过滤 + 简单排序                           | 距离计算 + 排序                       |
-| 批量计算    | 分步骤查询                                    | 复杂嵌套查询                          |
-
-#### 性能优化策略
-
-```sql
--- ✅ 推荐：利用索引的过滤查询
-SELECT doc_id, title FROM knowledge_base 
-WHERE COSINE_DISTANCE(embedding, ?) < 0.7
-ORDER BY doc_id LIMIT 10;
-
--- ✅ 可选：分步骤的Top-K检索
--- 步骤1：过滤候选
-CREATE VIEW candidates AS 
-SELECT doc_id, title FROM knowledge_base 
-WHERE COSINE_DISTANCE(embedding, ?) < 0.8;
-
--- 步骤2：精确排序（如需要）
-SELECT doc_id, title FROM candidates ORDER BY doc_id LIMIT 10;
-```

-## 🔄 迁移策略
-
-### 迁移价值评估
-
-在决定是否迁移到VECTOR类型之前，建议先评估您的使用场景：
-
-#### 高价值迁移场景
-
-* **频繁的向量相似度计算**：如推荐系统、文档检索、图像匹配
-* **大规模向量数据**：超过百万级别的向量数据查询
-* **复杂的UDF维护**：当前需要维护多个自定义向量计算函数
-* **性能要求高**：对查询响应时间有严格要求的应用
-
-#### 可选迁移场景
-
-* **偶尔的向量计算**：向量计算不是核心业务流程
-* **小规模数据**：向量数据量较小，性能压力不大
-* **稳定的现有系统**：当前系统运行稳定，改动风险大于收益
-
-### 针对不同用户的迁移建议
-
-#### Spark用户迁移路径
-
-**如果您主要使用Spark MLlib进行向量计算**：
-
-```python
-# 原Spark代码
-from pyspark.ml.linalg import Vectors, VectorUDT
-from pyspark.sql.functions import udf
-
-# 自定义相似度函数
-def cosine_similarity(v1, v2):
-    # 复杂的实现逻辑
-    pass
-
-# 注册UDF
-cosine_udf = udf(cosine_similarity, DoubleType())
-```
-
-**迁移到CloudZetta VECTOR后**：
-
-```sql
--- 直接使用内置函数和推荐查询模式
-SELECT user_id FROM user_features
-WHERE COSINE_DISTANCE(user_vector, target_vector) < 0.8;
-```
-
-**迁移收益**：
-
-* 删除自定义UDF代码
-* 利用向量索引加速查询
-* 统一在SQL中处理向量计算
-
-#### Hive用户迁移路径
-
-**如果您在Hive中使用ARRAY存储向量**：
-
-```sql
--- 原Hive表结构
-CREATE TABLE user_embeddings (
-    user_id BIGINT,
-    features ARRAY<DOUBLE>
-) PARTITIONED BY (dt STRING);
-
--- 需要复杂的UDF
-SELECT user_id, my_cosine_udf(features, target_array) as score
-FROM user_embeddings 
-WHERE size(features) = 128;  -- 手动维度检查
-```
-
-**迁移到 VECTOR 类型**：
-
-```sql
--- 新的表结构
-CREATE TABLE user_embeddings_v2 (
-    user_id BIGINT,
-    features VECTOR(FLOAT, 128)  -- 类型安全
-) PARTITIONED BY (dt STRING);
-
--- 使用内置函数和推荐模式
-SELECT user_id FROM user_embeddings_v2
-WHERE COSINE_DISTANCE(features, vector(...)) < 0.8;  -- 无需手动维度检查
-```
-
-### 评估现有系统
-
-#### 数据规模评估
-
-```sql
--- 统计现有向量数据的规模和维度
-SELECT 
-    table_name,
-    column_name,
-    COUNT(*) as record_count,
-    AVG(size(array_column)) as avg_dimension,
-    MIN(size(array_column)) as min_dimension,
-    MAX(size(array_column)) as max_dimension,
-    COUNT(DISTINCT size(array_column)) as dimension_variants
-FROM (
-    SELECT 'user_features' as table_name, 'embedding' as column_name, embedding as array_column FROM user_features
-    UNION ALL
-    SELECT 'product_vectors' as table_name, 'features' as column_name, features as array_column FROM product_vectors
-    -- 添加其他需要评估的表
-) all_vectors
-GROUP BY table_name, column_name;
-```
-
-#### UDF复杂度评估
-
-```sql
--- 识别当前使用的向量相关UDF
-SHOW FUNCTIONS LIKE '*similarity*';
-SHOW FUNCTIONS LIKE '*distance*';
-SHOW FUNCTIONS LIKE '*cosine*';
-SHOW FUNCTIONS LIKE '*euclidean*';
-```
-
-#### 查询频率评估
-
-```sql
--- 分析向量计算查询的频率（如果有查询日志）
-SELECT 
-    DATE(query_time) as query_date,
-    COUNT(*) as vector_query_count
-FROM query_logs 
-WHERE query_text LIKE '%cosine%' 
-    OR query_text LIKE '%similarity%'
-    OR query_text LIKE '%distance%'
-GROUP BY DATE(query_time)
-ORDER BY query_date DESC
-LIMIT 30;
-```
-
-### 并行构建新表
-
-```sql
--- 创建新的向量表
-CREATE TABLE embeddings_new (
-    id BIGINT,
-    content STRING,
-    embedding VECTOR(FLOAT, 768),
-    migrated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP(),
-    
-    INDEX embedding_idx (embedding) USING VECTOR PROPERTIES (
-        "distance.function" = "cosine_distance"
-    )
-);
-
--- 数据迁移
-INSERT INTO embeddings_new (id, content, embedding)
-SELECT 
-    id,
-    content,
-    CASE 
-        WHEN size(embedding_array) = 768 
-        THEN cast(embedding_array as VECTOR(FLOAT, 768))
-        ELSE NULL
-    END as embedding
-FROM embeddings_old
-WHERE size(embedding_array) = 768;
-
--- 构建索引
-BUILD INDEX embedding_idx ON embeddings_new;
-```
-
-### 验证迁移结果
-
-```sql
--- 对比查询结果的一致性（使用推荐查询模式）
-WITH old_results AS (
-    SELECT id FROM embeddings_old 
-    WHERE your_cosine_udf(embedding_array, ?) > 0.8
-    ORDER BY id LIMIT 10
-),
-new_results AS (
-    SELECT id FROM embeddings_new 
-    WHERE COSINE_DISTANCE(embedding, ?) < 0.2  -- 注意距离vs相似度的转换
-    ORDER BY id LIMIT 10
-)
-SELECT 
-    COALESCE(o.id, n.id) as id,
-    CASE WHEN o.id IS NOT NULL THEN 'OLD' ELSE NULL END as in_old,
-    CASE WHEN n.id IS NOT NULL THEN 'NEW' ELSE NULL END as in_new
-FROM old_results o
-FULL OUTER JOIN new_results n ON o.id = n.id
-ORDER BY id;
-```

-
-## 🚀 性能优化
-
-### 查询优化
-
-```sql
--- ✅ 推荐：使用阈值过滤提升查询效率
-SELECT id, content FROM embeddings_table 
-WHERE COSINE_DISTANCE(embedding, ?) < 0.8  -- 利用向量索引过滤
-ORDER BY id LIMIT 10;
-
--- ✅ 可选：分步骤处理复杂查询
-CREATE VIEW filtered_candidates AS
-SELECT id, content FROM embeddings_table 
-WHERE COSINE_DISTANCE(embedding, ?) < 0.8;
-
-SELECT id, content FROM filtered_candidates 
-ORDER BY id LIMIT 10;
-```
-
-### 存储优化
-
-```sql
--- 大规模数据使用半精度存储
-CREATE TABLE large_embeddings (
-    id BIGINT,
-    embedding VECTOR(FLOAT, 1536),
-    
-    INDEX embedding_idx (embedding) USING VECTOR PROPERTIES (
-        "scalar.type" = "f16",  -- 半精度存储节省内存
-        "distance.function" = "cosine_distance"
-    )
-);
-```
-
-### 索引调优
-
-根据应用需求选择合适的索引参数：
-
-* **实时查询场景**：较小的M值和ef\_construction，使用f16类型
-* **批量分析场景**：较大的M值和ef\_construction，使用f32类型
-* **存储优化场景**：使用f16或i8类型减少内存占用
-
-***
-
-## ⚠️ 注意事项
-
-### 功能限制
-
-* 向量维度在创建时确定，不支持动态调整
-* 向量不能用作分区键
-* JACCARD\_DISTANCE和HAMMING\_DISTANCE函数有特殊的类型要求
-* **当前版本的复杂 SELECT 查询存在限制，建议使用 WHERE 过滤模式**

-**性能优化**：支持专门的向量索引，提升大规模向量查询的效率
-
-**标准兼容**：兼容SQL语法，支持排序、分组等标准操作
-
-### 适用场景
-
-**推荐使用VECTOR的情况**：
-
-* 需要频繁进行向量相似度计算
-* 向量维度固定且明确
-* 希望利用向量索引提升查询性能
-* 新开发的AI应用项目
-
-**继续使用ARRAY的情况**：
-
-* 主要进行数组操作而非向量计算
-* 向量维度经常变化
-* 改造现有系统成本较高
-* 需要复杂的向量排序查询（当前限制）
-
-### 实施建议
-
-**评估阶段**：分析现有向量数据的规模和维度特征
-
-**试点验证**：选择小规模场景验证VECTOR的效果
-
-**逐步迁移**：采用并行构建的方式平滑迁移现有系统
-
-**持续优化**：根据实际使用情况调整索引参数和查询策略
-
-### 查询模式推荐
-
-**优先使用**：
-
-* WHERE子句中的向量过滤：`WHERE COSINE_DISTANCE(...) < threshold`
-* 简单的向量函数计算：`COSINE_DISTANCE(v1, v2)`
-
-**谨慎使用**：
-
-* 复杂的 SELECT 返回距离计算并排序
-* 大型向量的嵌套查询
-
-**替代方案**：
-
-* 分步骤查询：先过滤再排序
-* 预计算：批量计算距离后存储

-# Lakehouse 向量索引创建指南
-
-## 概述
-
-Lakehouse 提供完整的向量检索能力，包括向量数据类型、搜索函数和专用索引。向量作为固定维度的数值集合，可以表示 LLM 生成的文本嵌入、图像特征、时序数据等多种信息。
-系统原生支持 VECTOR 类型，能够高效存储和查询由大语言模型（LLM）等深度学习模型生成的向量嵌入。这些向量嵌入将非结构化数据（如文本、图像）转化为保留语义相似性的数值表示。通过构建专门的向量索引，Lakehouse 可以在海量数据中实现毫秒级的相似性搜索，为基于 LLM 的 RAG 应用、智能问答、语义搜索等 AI 场景提供高性能的基础设施支持。
-
-## 1. 准备工作
-
-### 1.1 创建测试 Schema
-
-```sql
--- 创建一个专门用于向量索引测试的 schema
-CREATE SCHEMA IF NOT EXISTS vector_demo COMMENT '向量索引演示';
-
--- 切换到新创建的 schema
-USE SCHEMA vector_demo;
-```
-
-### 1.2 准备向量生成函数
-
-Lakehouse 支持创建 AI 函数，可以将文本转换为向量表示，请参考：[创建 Embedding 函数](https://www.yunqi.tech/documents/Create_Embeding_Function)
-
-```sql
--- 函数签名
--- fc_embeddings(mode, text, api_key, model, dimension)
--- 参数说明：
--- mode: 'text' - 文本模式
--- text: 要转换的文本内容
--- api_key: API密钥 (请替换为您的实际密钥)
--- model: 模型名称，如 'text-embedding-v4'
--- dimension: 向量维度，如 1024
-
--- 测试向量生成函数
-SELECT public.fc_embeddings(
-    'text', 
-    'hello world', 
-    '${API_KEY}', 
-    'text-embedding-v4',
-    1024
-) as embedding;
-```
-
-## 2. 创建包含向量列的表
-
-### 创建产品描述表
-
-```sql
--- 创建产品表，包含向量列（简化版本，避免IDENTITY问题）
-CREATE TABLE IF NOT EXISTS vector_demo.product_embeddings (
-    product_id INT COMMENT '产品ID',
-    product_name VARCHAR(255) NOT NULL COMMENT '产品名称',
-    category VARCHAR(100) COMMENT '产品类别',
-    description STRING COMMENT '产品描述',
-    embedding VECTOR(FLOAT, 1024) COMMENT '产品描述的向量表示',
-    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP() COMMENT '创建时间',
-    
-    -- 创建向量索引（简化的语法）
-    INDEX idx_product_embedding (embedding) USING VECTOR
-) 
-COMMENT '产品向量表';
-
-```
-
-## 3. 插入向量数据
-
-### 3.1 使用向量生成函数插入数据
-
-**重要提示**：使用 `fc_embeddings` 函数生成的向量需要显式转换为 `VECTOR` 类型。
-
-```sql
--- 插入向量数据，注意需要使用 CAST 转换
-INSERT INTO vector_demo.product_embeddings (product_id, product_name, category, description, embedding)
-VALUES

-## 4. 构建向量索引
-
-> ### 对已有数据构建索引
->
-> 如果想对表中已经存在的数据创建索引，需要使用 BUILD INDEX 命令构建索引（新插入的数据会自动构建索引）。
->
-> ```sql
-> -- 构建向量索引（实际验证过的命令）
-> BUILD INDEX idx_embedding ON vector_demo.simple_embeddings;
->
-> -- 构建文档表的向量索引（指定范围）
-> BUILD INDEX idx_doc_embedding ON vector_demo.document_embeddings 
-> WHERE create_date >= '2024-01-01' AND create_date <= '2024-12-31';
-> ```
-
-### 4.1 监控索引构建进度
-
-```sql
--- 查看表的索引列表
-SHOW INDEXES FROM vector_demo.product_embeddings;
-
--- 查看表的详细信息，包括索引
-DESC EXTENDED vector_demo.product_embeddings ;
-```
-
-## 5. 使用向量索引进行相似度搜索
-
-### 5.1 基本向量搜索
-
-```sql
-WITH query_vector AS (
-    SELECT CAST(public.fc_embeddings(
-        'text', 
-        '拍照功能强大的手机，相机系统好，影像能力出色', 
-        '${API_KEY}', 
-        'text-embedding-v4',
-        1024
-    ) AS VECTOR(FLOAT, 1024)) as vec
-)
-SELECT 
-    p.product_id,
-    p.product_name,
-    p.category,
-    p.description,
-    cosine_distance(p.embedding, q.vec) as similarity_score
-FROM vector_demo.product_embeddings p, query_vector q
-ORDER BY similarity_score ASC
-LIMIT 5;
-
-```
-
-展示结果：

-### ![](.topwrite/assets/vector.jpeg)
-
-### 5.3 带过滤条件的向量搜索
-
-```sql
-WITH query_vector AS (
-    SELECT CAST(public.fc_embeddings(
-        'text', 
-        '国产高端旗舰手机', 
-        '${API_KEY}', 
-        'text-embedding-v4',
-        1024
-    ) AS VECTOR(FLOAT, 1024)) as vec
-)
-SELECT 
-    product_id,
-    product_name,
-    description,
-    ROUND(cosine_distance(embedding, vec), 4) as distance
-FROM vector_demo.product_embeddings, query_vector
-WHERE product_name NOT LIKE '%iPhone%'  -- 排除苹果产品
-ORDER BY distance ASC
-LIMIT 3;
-```
-
-展示结果：

-![](.topwrite/assets/vector_search_w_filter.jpeg)
-
-## 6. 向量索引优化建议
-
-### 6.1 距离函数选择
-
-| 距离函数                   | 适用场景  | 特点              |
-| ---------------------- | ----- | --------------- |
-| cosine_distance       | 文本相似度 | 不受向量长度影响，适合文本嵌入 |
-| l2_distance           | 图像特征  | 欧氏距离，对绝对差异敏感    |
-| negative_dot_product | 推荐系统  | 点积的负值，适合评分预测    |
-
-### 6.2 参数调优
-
-```sql
--- 高精度配置（查询准确但较慢）
-CREATE INDEX idx_high_precision (embedding) USING VECTOR 
-PROPERTIES(
-    "m" = "64",
-    "ef.construction" = "500",
-    "scalar.type" = "f32"
-);
-
--- 高性能配置（查询快速但精度略低）
-CREATE INDEX idx_high_performance (embedding) USING VECTOR 
-PROPERTIES(
-    "m" = "8",
-    "ef.construction" = "100",
-    "scalar.type" = "f16",
-    "compress.codec" = "lz4"
-);
-```
-
-### 6.3 存储优化
-
-```sql
--- 使用向量列复用减少存储
-CREATE INDEX idx_storage_optimized (embedding) USING VECTOR 
-PROPERTIES(
-    "reuse.vector.column" = "true",
-    "scalar.type" = "i8"  -- 使用8位整数进一步压缩
-);
-```
-
-## 7. 管理向量索引
-
-### 7.1 查看索引信息
-
-```sql
--- 查看表的所有索引
-SHOW INDEXES FROM vector_demo.product_embeddings;
-
--- 查看索引详细信息
-DESC INDEX idx_product_embedding ON vector_demo.product_embeddings;
-```
-
-### 7.2 删除和重建索引
-
-```sql
--- 删除索引
-DROP INDEX idx_product_embedding ON vector_demo.product_embeddings;
-
--- 重新创建索引（使用新参数）
-CREATE INDEX idx_product_embedding_v2 ON vector_demo.product_embeddings(embedding) 
-USING VECTOR PROPERTIES(
-    "distance.function" = "negative_dot_product",
-    "m" = "24",
-    "ef.construction" = "300"
-);
-
--- 构建新索引
-BUILD INDEX idx_product_embedding_v2 ON vector_demo.product_embeddings;
-```
-
-## 8. 性能监控和故障排查
-
-### 8.1 查询性能分析
-
-```sql
--- 使用 EXPLAIN 分析查询计划
-EXPLAIN 
-WITH query_vector AS (
-    SELECT public.fc_embeddings('text', '测试查询', '${API_KEY}', 'text-embedding-v4', 1024) as vec
-)
-SELECT * FROM vector_demo.product_embeddings p, query_vector q
-ORDER BY cosine_distance(p.embedding, q.vec) ASC
-LIMIT 10;
-```
-
-### 8.2 常见问题处理
-
-1. **索引构建失败**
-   * 检查内存是否充足
-   * 确认向量维度一致
-   * 验证向量数据完整性
-
-2. **查询性能慢**
-   * 调整 m 和 ef.construction 参数
-   * 考虑使用更小的 scalar.type
-   * 检查是否正确使用了索引
-
-3. **精度不足**
-   * 增加 m 值
-   * 提高 ef.construction
-   * 使用 f32 而非压缩格式
-
-## 重要注意事项
-
-1. **向量类型转换**：使用 `fc_embeddings` 函数生成的向量结果为 String 类型，需使用 `CAST` 转换为 `VECTOR(FLOAT, 1024)` 类型。
-
-2. **BUILD INDEX**：对于已有数据的表，必须执行 BUILD INDEX 命令来构建索引，否则向量搜索性能会受影响。
-
-3. **距离函数选择**：
-   * `cosine_distance`：适用于文本嵌入，值越小越相似
-   * `l2_distance`：欧氏距离，适用于图像特征
-   * `negative_dot_product`：点积的负值，适用于推荐系统
-
-4. **向量检索查询时支持的参数**
-
-   | Name                                                  | Default Value | Notes                                        |
-   | ----------------------------------------------------- | ------------- | -------------------------------------------- |
-   | cz.storage.parquet.vector.index.read.memory.cache     | false         | 是否使用内存缓存                                     |
-   | cz.storage.parquet.vector.index.read.local.cache      | false         | 是否使用本地SSD缓存                                  |
-   | cz.storage.parquet.vector.index.read.vectors.ondemand | adaptive      | 是否按需加载向量索引（比使用内存缓存稍慢）                        |
-   | cz.storage.parquet.vector.index.write.parallel        | 0             | 是否开启并行写入，0表示关闭，8表示8个线程写入。注意，性能提升比例并不与线程数成正比。 |
-
-   使用示例：使用SQL查询时选中一起执行。
-
-   ```
-   SET cz.sql.index.prewhere.enabled=true; -- 当前需要设置开关，后续版本会默认开启
-   SELECT id, doc, l2_distance(vec, vector(1,2,3,4)) as dist FROM some_table WHERE match_regexp(doc, '.*hello.*', map('analyzer', 'keyword')) AND l2_distance(vec, vector(1,2,3,4)) < 1000 ORDER BY dist LIMIT 100
-   ```
-
-5. **计费**
-
-   存储资源：向量索引会创建向量索引文件，该文件和数据文件都保存在对象存储中，统一计费。

-# 计算集群
-
-计算集群（Virtual-Cluster，简称：VCluster）是云器Lakehouse提供的一项核心服务，旨在为用户提供高效、可扩展的计算资源。计算集群为Lakehouse中的查询分析、ETL作业、流式分析和即席查询等任务提供必要的CPU、内存和临时存储资源。通过计算集群，用户可以在Lakehouse中执行各种复杂的数据处理任务。
-
-## 核心概念
-
-### 集群名称
-
-每个计算集群都需要一个唯一的名称，该名称在工作空间内必须唯一。集群名称一旦创建，将无法更改。在Lakehouse中，集群的完整标识由工作空间名称和计算集群名称共同构成。
-
-### 规格
-
-计算集群的规格定义了集群中每个计算副本可用的计算资源数量，以Compute Resource Unit（CRU）为单位。CRU是云器Lakehouse对IaaS计算资源算力的抽象，以便在不同云平台、不同CPU架构和规格下，均能获得一致的算力。
-
-说明：自2024年12月起，计算集群旧有从XS到5XLarge的规格代码变更为使用数字表达的规格。变更详见：[计算集群规格代码变更说明](vcluster_size_description.md)。
-
-| **类型**                         | **最小规格**（**CRU**） | **最大规格**（**CRU**） | **默认值**（**CRU**） | **步长**&#xA;（规格增减的最小单位）                                                                 |
-| ------------------------------ | ----------------- | ----------------- | ---------------- | -------------------------------------------------------------------------------------- |
-| 通用型&#xA;（GP VCluster）          | 1                 | 256               | 1                | 规格变更步长为：1CRU。&#xA;规格示例：1，2，3，4，5，6...256                                               |
-| 分析型&#xA;（AP VCluster）          | 1                 | 256               | 1                | 规格变更步长为：2的n次幂CRU。&#xA;规格示例：1，2，4，8，16，32，64，128，256                                   |
-| 同步型&#xA;（Integration VCluster） | 0.25              | 256               | 0.5              | 规格变更步长为：&#xA;有0.25 CRU和0.5 CRU两个特殊的小规格，其余步长为1 CRU。&#xA;规格示例：0.25，0.5，1，2，3，4，5，6...256 |
-
-每个集群每小时消耗的计算资源量为其CRU规格\*1小时，即单位为CRU\*时。例如规格为3 CRU的分析型计算集群，运行1小时的资源消耗为 3CRU \* 1小时=3CRU\*时。其费用也按照计算集群所在区域的“CRU\*时”的单价计算。
-
-### 集群类型
-
-计算集群分为通用型、分析型和同步型，三大类：
-
-* 通用型（GENERAL)）：适用于处理离线作业，作业之间共享计算资源，新旧作业采用公平调度方式分配计算资源。
-* 分析型(ANALYTICS)：具备多计算实例和自动弹缩功能，适合处理在线和高并发作业。当作业并发数达到上限时，后续作业将排队等待执行，确保先提交的作业优先执行。
-* 同步型(INTEGRATION)：适用于处理离线集成和实时集成任务。多个集成任务可共用一个同步型计算集群实例。超出集群计算能力的集成任务将进入队列排队。
-
-不同集群类型与下图中任务类型的对应关系如下：
-
-
-| **任务类型**            | **可使用集群类型** | **建议使用集群类型**                        |

-| SQL                 | 通用型、分析型     | **ETL任务**：通用型&#xA;**Ad-hoc查询**：分析型  |

-
-### 实例最小值
-
-仅分析型计算集群支持此属性。指计算集群初始启动时集群实例数量，默认为1 个实例。
-
-### 实例最大值
-
-仅分析型计算集群支持此属性。指计算集群可以使用的最大实例数量，默认为2 个实例。当新的查询超过当前实例的最大并发数时，将触发计算集群的自动扩容，新增一个计算集群实例。扩容计算集群实例的上限为实例最大值。
-
-### 自动停止
-
-当计算集群在自动停止配置指定的时间内无作业运行时，计算集群自动停止、释放资源，停止消耗计算费用。自动停止配置最小单位为“秒”，最小可配置为15秒。
-
-因运行不足1分钟的计算集群，将按照1分钟收费。所以当选择自动停止时间小于1分钟时，请谨慎确认，避免产生不必要的费用。1
-
-### 自动启动
-
-当有新作业提交时，若计算集群已停止，开启自动启动功能的计算集群将自动启动并执行作业。关闭该配置则指定计算集群需要手动启动。手动启动集群可参考本文中的“启动与停止集群”操作，或使用Alter Vcluster \<vcluster\_name> resume；语句。
-
-## 管理计算集群
-
-云器Lakehouse提供两种管理控制计算集群的方式：1）Web-UI方式；2）通过SQL方式。
-
-### Web-UI方式
-
-#### 查看集群信息
-
-登录Lakehouse平台，点击左侧菜单的“计算”功能，进入“计算集群”列表页面。在此页面，您可以查看当前工作空间内所有授权访问的计算集群。
-
-![](.topwrite/assets/image_1741611037239.png)
-
-点击任一集群名称，进入详情页面，您可以查看集群的作业执行情况、配置详情以及当前用户对该集群的权限。
-
-:-: ![](.topwrite/assets/image_1728532541352.png =805)
-
-#### 创建计算集群
-
-在“计算集群”列表页面，点击“新建集群”按钮，进入新建集群界面。填写集群名称、选择集群类型、配置规格等信息后，点击“创建集群”完成集群创建。新集群将在列表中显示，并在状态变为“运行中”后即可使用。

-
-:-: ![](.topwrite/assets/image_1742216967064.png =414)
-
-如果需要处理ETL等批量类型的作业，建议创建通用型计算集群：
-
-* 在“类型”属性中选择“通用型”。
-* 在“规格”属性中，可以选择“固定”和“弹性伸缩”两种方式。“固定”意味着该集群的规格大小不会随着负载而弹缩，可以有效控制集群所消耗资源，进而控制计算成本；“弹性伸缩”意味着该集群的规格大小会随着负载而弹缩，更有利于对任务SLA有强保障需求的场景。
-
-> 注意，通用型集群的弹性伸缩是以“最快完成当前提交至计算集群的所有任务”为目的，会在当前规格满载后，立即扩容至满足所有任务需求的规格大小。该策略更倾向于效率而非成本。因此请根据成本和效率的实际需要，合理选择“固定”或“弹性伸缩”的方式，以及弹性伸缩的最大、最小规格。
-
-* 选择是否开启“自动启动”和“自动停止”，并配置合理的“自动停止”时间。推荐开启“自动启动”，以及时处理作业任务，配置“自动停止”时间为1分钟，以当作业结束时能尽快关闭计算集群，节省成本。
-
-完成上述配置后，点击“确定”即完成通用型计算集群的创建。

-
-^
-
-如需要为即席查询或BI看板等查询分析场景提供计算资源，建议创建分析型集群：
-
-* 在“类型”属性中选择“通用型”。
-* 在“规格”属性中，选择符合业务需要的规格。规格大小通常和该计算集群要负载的请求并发数、查询数据量、查询复杂度正相关，与预期查询结果返回时间负相关。可以在创建计算集群后，通过并发测试，逐步调整至满足查询效率需要且能够取得最优成本的规格。
-* 选择是否开启“自动启动”和“自动停止”，并配置合理的“自动停止”时间。推荐开启“自动启动”，以及时处理作业任务，配置“自动停止”时间为30分钟以上，以尽量利用分析型集群的缓存加速查询结果，使终端用户获得更好的查询体验。
-* 配置“最大并发数”。最大并发数指该集群每个实例所能够支持的最大并发数，当作业并发数超过该值时，作业会开始排队或触发扩容新的实例。
-* “实例最小值”和“实例最大值”指该集群弹缩时的最小和最大实例数。当该计算集群当前所有实例的负载都达到“最大并发数”配置时，实例开始扩容，直至满足作业并发或达到“实例最大值”，实例扩容时，排队队列中的作业或新提交的作业会分配至新实例上，正在处理的作业不受影响；当该计算集群缩容一个实例仍可以满足所有并发时，开始缩容，直至缩容至能满足所有并发的最小实例数或该集群配置的“实例最小值”，实例缩容时，排队队列中的作业或新提交的作业不再分配至将要缩容的实例上，正在处理的作业不受影响，当正在处理的作业完成后，该实例完成释放。

-**创建同步型集群**
-

-
-如果需要处理离线或实时集成任务，需要创建同步型集群：
-
-* 在“类型”属性中选择“同步型”。
-* 在“规格”属性中，可以选择“固定”和“弹性伸缩”两种方式。“固定”意味着该集群的规格大小不会随着负载而弹缩，可以有效控制集群所消耗资源，进而控制计算成本；“弹性伸缩”意味着该集群的规格大小会随着负载而弹缩，更有利于对任务SLA有强保障需求的场景。
-
-> 注意，同步型集群的弹性伸缩是以“最快完成当前提交至计算集群的所有任务”为目的，会在当前规格满载后，立即扩容至满足所有任务需求的规格大小。该策略更倾向于效率而非成本。因此请根据成本和效率的实际需要，合理选择“固定”或“弹性伸缩”的方式，以及弹性伸缩的最大、最小规格。
-
-* 同步型计算集群提供了“规格预估”功能，辅助选择合适的同步型集群规格。可通过输入“任务数”和“平均任务并发数”，按照“规格=任务数 \* 平均任务并发数 \* 0.05”的公式计算出预估的集群规格。
-

-
-#### 修改计算集群属性
-
-在集群列表中，选择相应集群，点击“操作”列的“修改”按钮，即可对集群配置进行调整。修改后的集群配置可能影响集群状态，请注意在修改规格、实例数等关键属性时，确保集群上没有正在运行的作业。

-
-####
-
-#### 启动与停止计算集群
-
-在集群列表中，点击“操作”列的“启动”或“停止”按钮，即可对计算集群进行启动或停止操作。请注意，停止集群时，正在执行的作业将等待完成后集群才会停止。
-

-

-
-###
-
-#### 删除计算集群
-
-在集群列表中，点击“操作”列的“删除”按钮，即可删除指定的计算集群。删除集群前，需要先停止集群，并等待所有作业完成后才能完成删除操作。
-
-:-: ![](.topwrite/assets/image_1733812348735.png =810)
-

-
-### SQL方式
-
-除了Web-UI，Lakehouse还支持使用SQL命令直接操作计算集群。具体命令和使用方法，请参考[计算资源DDL](create_cluster.md)文档。

-
-## 计算集群配置实践
-
-#### 自动化管理计算集群
-
-计算集群实例可在停止状态下，被提交的任务唤醒，秒级启动并开始执行作业，并可在集群空闲时自动关机，以节约成本。充分利用这一特性，可使计算集群的成本尽量贴合业务的负载，大幅提高资源利用率。
-
-* 配置自动暂停和恢复：在创建或修改计算集群实例的窗口，可以找到“自动启动”和“自动停止”的配置项。通常情况下，这两个配置是配合进行配置的：打开“自动启动”，并且设置“自动停止”时间。
-* 设置合适的超时限制：计算集群的“自动停止”时间可以设置从1分钟到3小时不等。合理选择“自动停止”时间需要考虑到计算集群的启动和停止对作业带来的影响：
-* 1）对离线作业可以将“自动停止”时间设置得尽量短，例如1分钟。以便集群在完成作业后能够尽快停止运行，避免空闲时间带来的资源浪费。
-* 2）对在线查询服务则需要适当延长“自动停止”时间，例如30分钟。这样做首先可以尽量减少计算集群从“停止”状态到“启动”状态带来的查询请求延迟，保证查询体验；其次也可以尽量延长计算结果缓存的时间（针对分析型计算集群），提升查询效率。
-* 3）强烈不建议将“自动停止”时间配置到1分钟以内。由于计算集群计费是以秒级计费的，当运行时间不足60秒时会按照60秒计费。当配置自动停止时间为1分钟以内时，如果该计算集群上执行的作业运行时间非常短，可能造成1分钟内计算集群多次启动和停止，从而产生多个60秒的费用，造成费用上升。仅当对确认该集群上运行的作业时长不会造成集群1分钟内多次启停时，才可以配置自动停止时间小于1分钟。
-
-#### 合理扩大或减小计算集群规格
-
-实例规格是对虚拟集群进行垂直伸缩的选项，调整实例规格可以让单个作业获得更大的算力以提升作业性能。
-
-在实际的业务场景中，对于面向用户的数据产品往往有SLA的要求，如100并发下P99的查询延迟小于2秒。同时，也希望计算资源得到充分的利用，在满足业务需求的前提下尽可能降低资源成本。
-
-在实际业务使用中，推荐使用不同大小的计算集群规格运行查询（例如使用从8 CRU->1 CRU几种规格分别进行测试），找到集群规格尽可能小、同时性能下降不明显的资源规格。
-
-从业务负载类型、执行频率、作业并发、处理数据规模、SLA要求几个维度提供样例的资源规格设计，供参考使用：
-
-| 业务场景                      | 负载类型             | 执行频率   | 作业并发 | 处理数据规模 | VCluster类型 | 作业时延SLA               | VCluster Size |
-| ------------------------- | ---------------- | ------ | ---- | ------ | ---------- | --------------------- | ------------- |
-| ETL调度作业                   | 近实时离线处理          | 小时     | 1    | 1   TB | 通用型        | 15 分钟                 | 4             |

-
-#### 通过多计算资源实现负载隔离
-
-* 使用多个独立的计算支撑不同业务负载（Workload）。可根据周期性ELT、线上业务报表、分析师数据分析等不同需求，创建不同的计算资源并分配给不同的用户或应用使用，避免不同业务或人员资源争抢导致的SLA下降。
-  例如：
-
-* 周期性ELT任务和线上业务报表查询任务应当使用不同计算集群进行隔离，并分别使用通用型和分析型两种类型的计算集群，以充分发挥不同类型计算集群的性能特性，并且易于配置不同的自动停止时间——运行周期性ELT任务的计算集群的自动停止时间配置尽量短，比如1分钟；运行线上业务报表查询任务的计算集群自动停止时间配置稍长，比如5分钟。
-
-* 将运行大作业和小作业的计算集群进行隔离，为大作业配置较大规格的计算集群，保障大作业的运行时间，为小作业配置较小规格的计算集群避免不能跑满计算集群负载，造成资源浪费。

-## 基础文件管理
-
-### 🔍 文件列表查询
-
-```sql
--- 基础列表查询
-LIST USER VOLUME;
-LIST TABLE VOLUME my_table;
-LIST VOLUME mcp_demo.data_volume;
-
--- 子目录查询
-LIST USER VOLUME SUBDIRECTORY 'reports/2024/';
-LIST TABLE VOLUME my_table SUBDIRECTORY 'backups/';
-LIST VOLUME mcp_demo.data_volume SUBDIRECTORY 'csv_data/';
-
--- 正则表达式过滤
-LIST USER VOLUME REGEXP = '.*\.parquet';
-LIST TABLE VOLUME my_table REGEXP = '.*backup.*';
-LIST VOLUME mcp_demo.data_volume REGEXP = '.*month=0[1-5].*';
-
--- 组合查询：子目录+正则表达式
-LIST VOLUME mcp_demo.data_volume 
-SUBDIRECTORY 't_search_log' 
-REGEXP = '.*c000';
-```
-
-### 🗑️ 文件删除管理（REMOVE命令）
-
-```sql
--- 删除单个文件
-REMOVE USER VOLUME FILE 'temp/data.csv';
-REMOVE TABLE VOLUME my_table FILE 'backup/old_data.parquet';
-REMOVE VOLUME my_external_vol FILE 'processed/result.json';
-
--- 删除多个文件（需要多次执行REMOVE命令）
--- 注意：当前版本不支持逗号分隔的多文件删除方式
-REMOVE USER VOLUME FILE 'temp/file1.csv';
-REMOVE USER VOLUME FILE 'temp/file2.csv';
-
--- 删除整个目录（递归删除）
-REMOVE USER VOLUME SUBDIRECTORY 'temp/';
-REMOVE TABLE VOLUME my_table SUBDIRECTORY 'old_backups/';
-REMOVE VOLUME my_external_vol SUBDIRECTORY 'archive/2023/';
-
--- ⚠️ 注意：REMOVE会同时删除实际存储中的文件，不可恢复
-```
-
-### 📁 目录操作最佳实践
-
-```sql
--- 1. 按业务场景组织目录结构
--- 推荐目录结构：
--- /raw/           # 原始数据
--- /processed/     # 处理后数据  
--- /temp/          # 临时数据
--- /backup/        # 备份数据
--- /archive/       # 归档数据
-
--- 2. 按时间分区组织
-LIST USER VOLUME REGEXP = '.*2024.*';           -- 按年份
-LIST TABLE VOLUME my_table REGEXP = '.*202405.*'; -- 按年月
-LIST VOLUME external_vol REGEXP = '.*daily_20240529.*'; -- 按日期
-
--- 3. 按文件类型分类
-LIST USER VOLUME REGEXP = '.*\.csv';           -- CSV文件
-LIST TABLE VOLUME my_table REGEXP = '.*\.parquet'; -- Parquet文件
-LIST VOLUME external_vol REGEXP = '.*\.json';      -- JSON文件
-```
-
-### ⚠️ 文件管理注意事项
-
-1. **PUT/GET命令限制**: 只能在SQLLine等客户端中执行，Studio WEB端不支持
-2. **文件大小限制**: 单个文件不超过5GB
-3. **文件覆盖风险**: 同名文件会被自动覆盖，务必谨慎
-4. **权限依赖**: 操作权限与Volume类型相关（详见权限管理章节）
-
-***
-
-## 文件格式与压缩优化
-
-### 📦 支持的文件格式
-
-云器Lakehouse支持多种文件格式，每种格式都有其最佳使用场景：
-
-```sql
--- CSV格式：适用于数据交换、人工可读
--- Parquet格式：适用于分析场景、列式存储
--- JSON格式：适用于半结构化数据（输出为JSON LINE格式）
--- TEXT格式：适用于纯文本数据
--- ORC格式：优化的行列混合格式
--- BSON格式：二进制JSON格式
-```
-
-### 🗜️ 压缩格式配置
-
-> **注意**：根据验证测试，当前版本对于CSV格式的COMPRESSION参数可能存在限制。以下展示了推荐的语法：
-
-```sql
--- Parquet导出（推荐，自带内置压缩）
-COPY INTO USER VOLUME 
-SUBDIRECTORY 'parquet_data/'
-FROM my_table
-FILE_FORMAT = (TYPE = PARQUET);  -- 自动应用最优压缩
-
--- TEXT格式导出（纯文本）
-COPY INTO USER VOLUME 
-SUBDIRECTORY 'text_output/'
-FROM my_table
-FILE_FORMAT = (TYPE = TEXT);
-
--- 导入时的压缩参数设置（在OPTIONS中）
-COPY INTO target_table
-FROM USER VOLUME
-USING CSV
-OPTIONS('header'='true')
-FILES ('data.csv');
-```
-
-### 🔧 文件格式参数说明
-
-```sql
--- CSV导入时的参数设置
-COPY INTO target_table
-FROM USER VOLUME
-USING CSV
-OPTIONS(
-    'header'='true',              -- 包含表头
-    'sep'='|'                     -- 分隔符
-)
-FILES ('special_format.csv');
-```
-
-### 💡 格式选择建议
-
-| 格式               | 压缩比 | 查询性能 | 适用场景         |
-| ---------------- | --- | ---- | ------------ |
-| **Parquet** (推荐) | 高   | 最佳   | 分析查询、长期存储    |
-| **CSV**          | 中等  | 中等   | 数据交换、人工查看    |
-| **JSON**         | 中等  | 中等   | 半结构化数据、API接口 |
-| **TEXT**         | 低   | 低    | 日志文件、简单文本    |
-
-> **📋 最佳实践**：生产环境下存储分析数据优先选择Parquet格式，可减少50-80%存储空间并提升3-5倍查询性能。数据交换场景可使用CSV格式。
-
-***
-
-## 错误处理与数据质量
-
-### 🚫 错误处理策略
-
-> **注意**：根据验证测试，当前版本的ON\_ERROR参数语法可能存在限制。以下是建议的替代方法：
-
-```sql
--- 导入错误处理
--- 当遇到错误时，系统会默认返回详细的错误信息
-COPY INTO target_table
-FROM USER VOLUME
-USING CSV
-OPTIONS('header'='true')
-FILES ('import_data.csv');
-
--- 对于可能的格式错误，建议先导入小样本进行验证
-COPY INTO target_table
-FROM USER VOLUME
-USING CSV
-OPTIONS('header'='true')
-FILES ('sample_data.csv');
-```
-
-### 🧹 PURGE自动清理功能
-
-PURGE功能可以在数据导入成功后自动删除源文件，节省存储空间：
-
-```sql
--- 导入成功后自动删除源文件
-COPY INTO target_table
-FROM USER VOLUME
-(id INT, name STRING, value DOUBLE)
-USING CSV
-FILES ('import_data.csv')
-PURGE = TRUE;  -- ⚠️ 导入成功后源文件将被永久删除
-
--- 完整导入示例
-COPY INTO sales_data
-FROM VOLUME data_lake_volume
-(order_id BIGINT, customer_name STRING, amount DECIMAL(10,2), order_date DATE)
-USING CSV
-OPTIONS('header'='true', 'sep'=',')
-SUBDIRECTORY 'daily_sales/'
-PURGE = TRUE;            -- 成功后清理
-```
-
-### ⚠️ 数据质量保障建议
-
-1. **先小批量测试**: 使用小数据集验证格式和参数
-2. **错误日志分析**: 仔细分析错误原因进行调整
-3. **备份源文件**: 使用PURGE前确保有备份
-4. **格式验证**: 导入前验证文件格式一致性
-

-
-## 预签名URL最佳实践
-
-### 🔗 基础URL生成
-
-```sql
--- 为User Volume文件生成预签名URL
-SELECT GET_PRESIGNED_URL(USER VOLUME, 'data/report.csv', 3600) AS url;
-
--- 为Table Volume文件生成预签名URL
-SELECT GET_PRESIGNED_URL(TABLE VOLUME my_table, 'backup/data.parquet', 3600) AS url;
-
--- 为External Volume文件生成预签名URL  
-SELECT GET_PRESIGNED_URL(VOLUME mcp_demo.data_volume, 'path/file.csv', 3600) AS url;
-
--- 为Named Volume文件生成预签名URL
-SELECT GET_PRESIGNED_URL(VOLUME my_schema.my_named_volume, 'shared/report.pdf', 7200) AS url;
-```
-
-### 🌐 外部URL控制
-
-```sql
--- 设置强制生成外部可访问URL
-SET cz.sql.function.get.presigned.url.force.external=true;
-
--- 生成外部URL（推荐用于分享）
-SELECT GET_PRESIGNED_URL(USER VOLUME, 'report.pdf', 7200) AS external_url;
-
--- 批量生成URL（用于文件分享清单）
-SELECT 
-    relative_path,
-    size,
-    GET_PRESIGNED_URL(USER VOLUME, relative_path, 
-        CASE 
-            WHEN relative_path LIKE '%temp%' THEN 1800      -- 临时文件30分钟
-            WHEN relative_path LIKE '%archive%' THEN 86400  -- 归档文件24小时
-            ELSE 3600                                       -- 默认1小时
-        END
-    ) AS access_url
-FROM (SHOW USER VOLUME DIRECTORY)
-WHERE relative_path LIKE '%.csv';
-```
-
-### ⏰ 有效期管理策略
-
-```sql
--- 短期访问（30分钟）- 适用于临时下载
-SELECT GET_PRESIGNED_URL(USER VOLUME, 'temp.csv', 1800) AS short_url;
-
--- 标准访问（1小时）- 适用于常规操作
-SELECT GET_PRESIGNED_URL(USER VOLUME, 'data.csv', 3600) AS standard_url;
-
--- 长期访问（12小时）- 适用于大文件下载
-SELECT GET_PRESIGNED_URL(USER VOLUME, 'large_archive.zip', 43200) AS long_url;
-
--- 超长期访问（7天）- 适用于跨时区协作
-SELECT GET_PRESIGNED_URL(USER VOLUME, 'shared_report.xlsx', 604800) AS week_url;
-```
-
-### 🔐 安全最佳实践
-
-1. **最小权限原则**: 设置尽可能短的有效期
-2. **访问记录**: 生成URL时记录访问目的和有效期
-3. **定期清理**: 定期清理过期的预签名URL记录
-4. **监控异常**: 监控URL异常访问模式
-5. **外部访问控制**: 仅在必要时启用外部访问
-
-> **📋 最佳实践**：根据数据敏感程度分级设置URL有效期：公开数据≤7天，内部数据≤24小时，敏感数据≤1小时。

-## PIPE管道自动化
-
-### 🔧 前提条件与环境准备
-
-```sql
--- 1. 确认Virtual Cluster状态
-SHOW VCLUSTERS;
-
--- 2. 启动Virtual Cluster（如需要）
-ALTER VCLUSTER DEFAULT RESUME;
-
--- 3. 确认使用External Volume（仅External Volume支持PIPE）
-SHOW VOLUMES;
-DESC VOLUME schema_name.volume_name;
-```
-
-### 🚰 创建PIPE管道
-
-```sql
--- 创建目标表
-CREATE TABLE IF NOT EXISTS auto_import_target (
-    id INT,
-    name STRING,
-    data_content STRING,
-    ingestion_time TIMESTAMP_NTZ DEFAULT CURRENT_TIMESTAMP(),
-    source_file STRING  -- 记录来源文件
-);
-
--- 创建基础PIPE（仅支持External Volume）
-CREATE PIPE IF NOT EXISTS data_auto_import_pipe
-VIRTUAL_CLUSTER = 'DEFAULT'
-INGEST_MODE = 'LIST_PURGE'
-COMMENT 'External Volume自动数据导入管道'
-AS COPY INTO auto_import_target (id, name, data_content)
-FROM VOLUME mcp_demo.data_volume
-(id INT, name STRING, data_content STRING)
-USING CSV
-OPTIONS('header'='false')
-PURGE = true;
-
--- 创建优化PIPE（生产环境推荐）
-CREATE PIPE optimized_auto_pipe
-VIRTUAL_CLUSTER = 'DEFAULT'
-BATCH_INTERVAL_IN_SECONDS = 60        -- 批处理间隔
-BATCH_SIZE_PER_KAFKA_PARTITION = 10000 -- 批处理大小
-INGEST_MODE = 'LIST_PURGE'
-COMMENT '生产级自动导入管道'
-AS COPY INTO auto_import_target (id, name, data_content)
-FROM VOLUME mcp_demo.data_volume
-(id INT, name STRING, data_content STRING)
-USING CSV
-OPTIONS('header'='true')
-PURGE = true;          -- 处理后清理
-```
-
-### 📊 PIPE管理与监控
-
-```sql
--- 查看所有PIPE
-SHOW PIPES;
-
--- 查看PIPE详细信息
-DESC PIPE data_auto_import_pipe;
-
--- 暂停PIPE（正确语法）
-ALTER PIPE data_auto_import_pipe SET PIPE_EXECUTION_PAUSED = true;
-
--- 恢复PIPE（正确语法）
-ALTER PIPE data_auto_import_pipe SET PIPE_EXECUTION_PAUSED = false;
-
--- 删除PIPE
-DROP PIPE IF EXISTS data_auto_import_pipe;
-```
-
-### ⚠️ PIPE使用限制与注意事项
-
-1. **仅支持External Volume**: User Volume和Table Volume不支持PIPE监控
-2. **新文件监控**: PIPE用于监控新增文件，不能指定现有文件
-3. **Virtual Cluster依赖**: 需要可用的Virtual Cluster执行
-4. **权限要求**: 需要对Volume和目标表的相应权限
-5. **性能考虑**: 合理设置批处理参数避免资源浪费
-
-> **🔄 自动化建议**：对于需要实时/准实时导入的数据流，推荐使用PIPE配合External Volume，可实现全自动的数据摄取流程。

-SUBDIRECTORY 'daily_backup/2024-05-29/'
-FROM important_table
-FILE_FORMAT = (TYPE = PARQUET);
-
--- Step 3: 处理完成后导入（通常由外部ETL工具完成处理步骤）
-COPY INTO processed_table
-FROM USER VOLUME
-(id INT, name STRING, processed_value DOUBLE, processed_time TIMESTAMP_NTZ)
-USING CSV
-OPTIONS('header'='true')
-SUBDIRECTORY 'etl/processed/'
-PURGE = TRUE;  -- 导入成功后清理临时文件
-
--- Step 4: 验证数据质量
-SELECT 
-    COUNT(*) as total_rows,
-    COUNT(DISTINCT id) as unique_ids,
-    MAX(processed_time) as latest_processed,
-    MIN(processed_time) as earliest_processed
-FROM processed_table
-WHERE DATE(processed_time) = CURRENT_DATE;
-```
-
-> **💡 ETL流程优化**：使用User Volume作为临时处理区，Table Volume作为备份区，External Volume作为长期存储区，形成完整的数据生命周期管理。

-## Volume小文件优化
-
-### 📊 分析Volume存储使用情况
-
-```sql
-SELECT 
-    'User Volume' as volume_type,
-    COUNT(*) as file_count,
-    SUM(CAST(size AS BIGINT)) / 1024 / 1024 as total_size_mb,
-    AVG(CAST(size AS BIGINT)) / 1024 as avg_file_size_kb,
-    MIN(CAST(size AS BIGINT)) as min_size,
-    MAX(CAST(size AS BIGINT)) as max_size
-FROM (SHOW USER VOLUME DIRECTORY)
-UNION ALL
-SELECT 
-    'External Volume' as volume_type,
-    COUNT(*) as file_count,
-    SUM(CAST(size AS BIGINT)) / 1024 / 1024 as total_size_mb,
-    AVG(CAST(size AS BIGINT)) / 1024 as avg_file_size_kb,
-    MIN(CAST(size AS BIGINT)) as min_size,
-    MAX(CAST(size AS BIGINT)) as max_size
-FROM DIRECTORY(VOLUME mcp_demo.data_volume);
-```
-
-### 🔍 识别小文件问题
-
-< 1048576  -- 小于1MB的文件
-ORDER BY size_bytes ASC
-LIMIT 20;
-```
-
-### 🔧 Volume文件合并策略
-
-```sql
--- 1. 使用导出合并
--- 从多个小文件导入后再导出为单个大文件
-COPY INTO consolidated_table
-FROM VOLUME mcp_demo.data_volume
-(id INT, name STRING, value DOUBLE)
-USING CSV
-SUBDIRECTORY 'small_files/';
-
-COPY INTO VOLUME mcp_demo.data_volume
-SUBDIRECTORY 'consolidated/'
-FROM consolidated_table
-FILE_FORMAT = (TYPE = PARQUET);
-
--- 2. 定期归档合并
--- 将旧数据合并为较大文件存档
-COPY INTO archive_table
-FROM VOLUME mcp_demo.data_volume
-(id INT, name STRING, date_field DATE, value DOUBLE)
-USING CSV
-SUBDIRECTORY 'daily_data/'
-FILES ('day_20240101.csv', 'day_20240102.csv', 'day_20240103.csv');
-
-COPY INTO VOLUME mcp_demo.data_volume
-SUBDIRECTORY 'archive/2024/01/'
-FROM archive_table
-FILE_FORMAT = (TYPE = PARQUET);
-```
-
-### 💡 Volume存储优化建议
-
-1. **文件大小控制**: 单文件建议100MB-1GB之间
-2. **合并策略**: 定期将同类小文件合并为大文件
-3. **分层存储**: 将频繁访问文件和归档文件分开存储
-4. **格式转换**: 将CSV等格式文件转换为Parquet格式
-5. **定期清理**: 清理临时文件和过期数据
-
-> **🔧 优化目标**：对于分析型工作负载，理想的Volume文件大小为128MB-1GB；对于频繁读写的操作型工作负载，文件大小可保持在32MB-128MB之间。

-
-## 权限管理与安全控制
-
-### 🔐 Volume权限体系
-
-不同类型的Volume有不同的权限管理模式：
-
-```sql
--- User Volume权限（用户默认拥有管理权限）
--- 无需额外授权，用户对自己的User Volume拥有完全控制权
-
--- Table Volume权限（与表权限联动）
--- 需要对应表的权限才能操作Table Volume：
--- SELECT 权限 → SHOW/LIST/GET 操作
--- INSERT/UPDATE/DELETE 权限 → PUT/REMOVE 操作
-
--- External Volume权限（需要显式授权）
-GRANT READ VOLUME ON VOLUME schema_name.external_volume_name TO USER username;
-GRANT WRITE VOLUME ON VOLUME schema_name.external_volume_name TO USER username;
-GRANT ALL ON VOLUME schema_name.external_volume_name TO ROLE data_engineer;
-```
-
-### 👥 权限管理最佳实践
-
-```sql
--- 创建角色化权限管理
-CREATE ROLE data_reader;
-CREATE ROLE data_writer;
-CREATE ROLE data_admin;
-
--- 批量权限授予
-GRANT READ VOLUME ON VOLUME schema_name.shared_volume TO ROLE data_reader;
-GRANT READ VOLUME, WRITE VOLUME ON VOLUME schema_name.shared_volume TO ROLE data_writer;
-GRANT ALL ON VOLUME schema_name.shared_volume TO ROLE data_admin;
-
--- 用户角色分配
-GRANT ROLE data_reader TO USER analyst_team;
-GRANT ROLE data_writer TO USER etl_team;
-GRANT ROLE data_admin TO USER admin_user;
-
--- 查看Volume权限
-SHOW GRANTS ON VOLUME schema_name.volume_name;
-
--- 查看用户权限
-SHOW GRANTS TO USER username;
-
--- 回收权限
-REVOKE WRITE VOLUME ON VOLUME schema_name.volume_name FROM USER username;
-```
-
-### 🛡️ 安全配置建议
-
-```sql
--- 预签名URL安全设置
-SET cz.sql.function.get.presigned.url.force.external=true;  -- 仅在需要时启用
-
--- 定期权限审计
-SHOW GRANTS ON VOLUME schema_name.volume_name;
-```
-
-> **🔒 安全原则**：对于生产环境，建议采用基于角色的权限管理模式，将Volume权限与用户角色绑定，避免直接对用户授权，便于后期权限维护。

-
-## 成本优化建议
-
-### 💰 存储成本优化
-
-```sql
--- 存储空间分析
-SELECT 
-    volume_type,
-    file_format,
-    file_count,
-    ROUND(total_size_gb, 2) as size_gb,
-    ROUND(total_size_gb * 0.15, 2) as estimated_monthly_cost_usd  -- 估算成本
-FROM (
-    SELECT 
-        'External Volume' as volume_type,
-        CASE 
-            WHEN relative_path LIKE '%.parquet' THEN 'Parquet'
-            WHEN relative_path LIKE '%.csv' THEN 'CSV'
-            WHEN relative_path LIKE '%.json' THEN 'JSON'
-            ELSE 'Other'
-        END as file_format,
-        COUNT(*) as file_count,
-        SUM(CAST(size AS BIGINT)) / 1024 / 1024 / 1024 as total_size_gb
-    FROM DIRECTORY(VOLUME mcp_demo.data_volume)
-    GROUP BY 
-        CASE 
-            WHEN relative_path LIKE '%.parquet' THEN 'Parquet'
-            WHEN relative_path LIKE '%.csv' THEN 'CSV'
-            WHEN relative_path LIKE '%.json' THEN 'JSON'
-            ELSE 'Other'
-        END
-) subq
-ORDER BY total_size_gb DESC;
-```
-
-### 🌐 网络传输成本优化
-
-1. **同Region部署**: 确保Lakehouse与Volume存储在同一区域
-2. **内网传输**: 同云厂商同Region使用内网传输，避免公网费用
-3. **批量操作**: 批量导入导出减少网络请求次数
-
-### ⚡ 计算资源优化
-
-```sql
--- 选择合适的计算集群类型
--- 批量数据处理：建议使用通用型计算集群 (GENERAL PURPOSE VIRTUAL CLUSTER)
--- 实时查询：使用分析型计算集群
-
--- 检查当前集群配置
-SHOW VCLUSTERS;
-
--- 优化建议：
--- 1. 导入数据时使用通用型集群
--- 2. 启用自动小文件合并（仅通用型集群支持）
--- 3. 合理设置PIPE批处理参数
-```
-
-### 📊 成本监控建议
-
-1. **定期存储审计**: 每月分析存储使用情况
-2. **文件生命周期管理**: 设置数据归档和清理策略
-3. **网络传输监控**: 监控跨Region数据传输量
-
-> **💲 成本控制目标**：转换到Parquet格式可减少40-60%存储成本；合理的生命周期管理可减少20-30%的存储开销；使用内网传输可减少90%以上的网络传输费用。

-## 窗口函数（Window Functions）
-
-窗口函数（Window Functions）是一种强大的SQL函数，它允许用户在一个查询中对数据集进行分组计算。与传统的聚合函数不同，窗口函数可以对每一行数据进行计算，同时保留原始数据的详细信息。窗口函数在数据分析、报表生成等场景中具有广泛的应用，例如计算排名、累计和、移动平均等。
-
-## 窗口函数的基本语法
-
-窗口函数的基本语法如下：
-
-```SQL
-<window_function> OVER (
-    [PARTITION BY <partition_expression>]
-    [ORDER BY <order_expression>]
-)
-```
-
-* `<window_function>`：指定要使用的窗口函数，如`ROW_NUMBER()`、`RANK()`、`SUM()`等。
-* `PARTITION BY`：将数据集划分为不同的分区，每个分区是一个独立的计算范围。
-* `ORDER BY`：在每个分区内对数据进行排序，影响部分窗口函数的计算结果。
-
-## 窗口函数的分类
-
-根据功能和返回值类型，窗口函数可分为以下几类：
-
-1.  **排名函数（Ranking Functions）**：对数据进行排名，返回表示相对位置的整数值。常用排名函数包括`ROW_NUMBER()`、`RANK()`、`DENSE_RANK()`、`PERCENT_RANK()`、`CUME_DIST()`、`NTILE()`等。
-2.  **聚合函数（Aggregate Functions）**：对数据进行聚合计算，返回表示整体特征的值。Lakehouse支持所有标准的聚合函数。
-3.  **分析函数（Analytic Functions）**：对数据进行分析计算，返回表示数据特征的值。常用分析函数包括`FIRST_VALUE()`、`LAST_VALUE()`、`LAG()`、`LEAD()`、`NTH_VALUE()`、`CUME_DIST()`等。
-
-## 窗口函数的使用示例
-
-以下是一些使用窗口函数的SQL查询示例及其输出结果。假设我们有一个名为 `sales` 的表，它包含了每个月的销售额和利润率数据，如下所示：
-
-```SQL
-CREATE    TABLE sales (MONTH int, sales int, profit double);
-INSERT    INTO sales (MONTH, sales, profit)
-VALUES    (1, 100, 0.1),
-          (2, 120, 0.15),
-          (3, 80, 0.05),
-          (4, 150, 0.2),
-          (5, 90, 0.1),
-          (6, 110, 0.12);
-```
-
-### Ranking Functions
-
-* 查询：使用`ROW_NUMBER()`函数对销售额进行降序排名。
-
-```SQL
-SELECT month, sales, ROW_NUMBER() OVER (ORDER BY sales DESC) AS rank
-FROM sales;
-+-------+-------+------+
-| month | sales | rank |
-+-------+-------+------+
-| 4     | 150   | 1    |
-| 2     | 120   | 2    |

-| 5     | 90    | 5    |
-| 3     | 80    | 6    |
-+-------+-------+------+
-```
-
-* 查询：使用`RANK()`函数对利润率进行升序排名，并按照季度进行分组。
-
-```SQL
-SELECT month, profit, RANK() OVER (PARTITION BY CEIL(month / 3) ORDER BY profit ASC) AS rank
-FROM sales;
-+-------+--------+------+
-| month | profit | rank |
-+-------+--------+------+
-| 3     | 0.05   | 1    |
-| 1     | 0.1    | 2    |
-| 2     | 0.15   | 3    |
-| 5     | 0.1    | 1    |
-| 6     | 0.12   | 2    |
-| 4     | 0.2    | 3    |
-+-------+--------+------+
-```
-
-### Aggregate Functions
-
-* 查询：使用`AVG()`函数计算每个月的销售额与全年平均销售额的差值。
-
-```SQL
-SELECT month, sales, sales - AVG(sales) OVER () AS diff
-FROM sales;
-+-------+-------+--------------------+
-| month | sales |        diff        |
-+-------+-------+--------------------+

-# Window Frame
-
-Window Frame 是在使用窗口函数时定义的一个子集，用于限制窗口函数的计算范围，只对窗口框架中的数据进行计算。通过窗口框架，可以更加精确地控制窗口函数的计算方式和结果。以下是窗口框架的详细说明和使用示例。
-
-## Window Frame语法
-
-在使用窗口函数时，可以通过 `OVER` 子句定义窗口框架，语法如下：
-
-```SQL
-<window_function> OVER (
-    [PARTITION BY <partition_expression>]
-    [ORDER BY <order_expression>]
-    [frame_clause>]
-)
-```
-
-其中，`<window_function>` 表示要使用的窗口函数名称，例如 `ROW_NUMBER()`、`RANK()`、`SUM()` 等。`PARTITION BY` 子句用于将数据分组，每个分组称为一个分区（partition）。`ORDER BY` 子句用于在每个分区中对数据进行排序，这将影响某些窗口函数的结果，如 `ROW_NUMBER()`、`RANK()` 等。`frame_clause` 用于定义窗口框架的范围，有两种形式：`ROWS frame` 和 `RANGE frame`。
-
-### ROWS frame
-
-`ROWS frame` 是基于行的窗口框架，用于指定窗口框架中包含的行数或位置。其语法如下：
-
-```SQL
-ROWS BETWEEN <start_boundary> AND <end_boundary>
-```
-
-`<start_boundary>` 和 `<end_boundary>` 用于定义窗口框架的起始和结束边界，可以是以下值之一：
-
-- `UNBOUNDED PRECEDING`：从分区的第一行开始。
-- `UNBOUNDED FOLLOWING`：到分区的最后一行结束。
-- `CURRENT ROW`：当前行。
-- `<offset> PRECEDING`：当前行之前的第`<offset>`行，`<offset>`为非负整数。
-- `<offset> FOLLOWING`：当前行之后的第`<offset>`行，`<offset>`为非负整数。
-
-### RANGE frame
-
-`RANGE frame` 是基于值的窗口框架，用于指定窗口框架中包含的行的值的范围。其语法如下：
-
-```SQL
-RANGE BETWEEN <start_boundary> AND <end_boundary>
-```
-
-`<start_boundary>` 和 `<end_boundary>` 用于定义窗口框架的起始和结束边界，可以是以下值之一：
-
-- `UNBOUNDED PRECEDING`：从分区中最小值开始。
-- `UNBOUNDED FOLLOWING`：到分区中最大值结束。
-- `CURRENT ROW`：当前行的值。
-- `<value> PRECEDING`：当前行的值减去`<value>`，`<value>`为非负数。
-- `<value> FOLLOWING`：当前行的值加上`<value>`，`<value>`为非负数。
-
-## Window Frame的使用示例
-
-以下是一些使用 Window Frame 的 SQL 查询示例，以及它们的输出结果。假设我们有一个名为 sales 的表，它包含了每个月的销售额和利润率的数据，如下所示：
-
-
-
-| month | sales | profit |
-| ----- | ----- | ------ |
-| 1     | 100   | 0.1    |
-| 2     | 120   | 0.15   |
-| 3     | 80    | 0.05   |
-| 4     | 150   | 0.2    |
-| 5     | 90    | 0.1    |
-| 6     | 110   | 0.12   |
-
-
-
-### ROWS frame
-
-* 查询：使用 `SUM()` 函数和 `ROWS frame` 计算每个月的销售额与前两个月和后两个月的销售额的总和。
-
-```SQL
-SELECT month, sales, SUM(sales) OVER (ORDER BY month ROWS BETWEEN 2 PRECEDING AND 2 FOLLOWING) AS sum_sales
-FROM sales;
-
-+-------+-------+-----------+
-| month | sales | sum_sales |
-+-------+-------+-----------+
-| 1     | 100   | 300       |
-| 2     | 120   | 450       |

-| 5     | 90    | 430       |
-| 6     | 110   | 350       |
-+-------+-------+-----------+
-```
-
-* 查询：使用 `AVG()` 函数和 `ROWS frame` 计算每个月的利润率与前一个月和后一个月的利润率的平均值。
-
-```SQL
-SELECT month, profit, AVG(profit) OVER (ORDER BY month ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING) AS avg_profit
-FROM sales;
-+-------+--------+---------------------+
-| month | profit |     avg_profit      |
-+-------+--------+---------------------+
-| 1     | 0.1    | 0.125               |
-| 2     | 0.15   | 0.09999999999999999 |
-| 3     | 0.05   | 0.13333333333333333 |
-| 4     | 0.2    | 0.11666666666666665 |
-| 5     | 0.1    | 0.14                |
-| 6     | 0.12   | 0.11                |
-+-------+--------+---------------------+
-```
-
-### RANGE frame
-
-* 查询：使用 `COUNT()` 函数和 `RANGE frame` 计算每个月的销售额在全年销售额中的分布，即有多少个月的销售额与当前月的销售额相差不超过 10。
-
-```SQL
-SELECT month, sales, COUNT(*) OVER (ORDER BY sales RANGE BETWEEN 10 PRECEDING AND 10 FOLLOWING) AS count_sales
-FROM sales;
-+-------+-------+-------------+
-| month | sales | count_sales |

-+-------+-------+-------------+
-```
-
-* 查询：使用 `MAX()` 函数和 `RANGE frame` 计算每个月的利润率与前一个月和后一个月的利润率的最大值。
-
-```SQL
-SELECT month, profit, MAX(profit) OVER (ORDER BY month RANGE BETWEEN 1 PRECEDING AND 1 FOLLOWING) AS max_profit
-FROM sales;
-+-------+--------+------------+

-# 使用Lakehouse计算集群
-
-## 一、概述：为什么需要“计算集群”？
-
-在云器Lakehouse中，无论是执行离线/实时数据集成，进行复杂的ETL任务，还是进行实时/离线的交互式查询，都需要使用Lakehouse提供的计算集群（Virtual Cluster，简称Vcluster）。计算集群支持：
-
-* **按需启动与停止**：无查询或作业时可自动停止，避免资源闲置带来的成本浪费；有新作业或查询到来时可自动启动，保障及时处理。
-* **灵活规格选择**：可根据作业负载和并发度，快速“垂直扩容”或“水平扩展”。
-* **多种使用方式**：可通过Web界面或SQL DDL命令方式完成集群创建、启动、停止、调整大小、权限管理等操作。
-
-这份文档将结合**Lakehouse计算集群**的特性与操作方法，结合实际应用场景给出一些应用示例和最佳实践。
-
-## 二、核心概念与主要功能
-
-### 1. 集群名称
-
-每个云器计算集群都有唯一名称，在其所在的工作空间下不可重复。计算集群一旦创建，名称不可更改。
-
-### 2. 规格
-
-在Lakehouse中，规格以 “CRU（Compute Resource Unit）”为单位，如（1CRU，2CRU，4CRU...直至256CRU）。根据需求可选择**通用型/分析型/同步型**集群，并配置对应的集群大小。
-
-**注意**：更大规格的集群意味着更高的负载能力和查询性能，同时也会产生更高的成本。可根据业务负载和成本预期，在使用过程中调整、优化集群规格。
-
-### 3. 集群类型
-
-Lakehouse计算集群分为通用型（General Purpose 简称：GP）、分析型（Analytics Purpose，简称AP）和同步型（Integration Purpose，简称：Integration）。
-
-* 通用型（GP）：适合离线作业或综合场景，同一计算集群中的作业资源共享、公平调度。可自动弹缩规格大小（纵向扩缩容）。
-* 分析型（AP）：适合ad-hoc和高并发在线作业场景，同一计算集群中的作业独占资源，根据作业先后排队执行。可根据并发负载自动弹缩副本数（横向扩缩容）。
-* 同步型（Integration）：适合实时/离线数据集成等同步任务，多个集成任务可共用一个实例，可根据负载自动弹缩规格大小（纵向扩缩容）。
-
-### 4. 自动启动 & 自动停止
-
-**自动启动**：当有新的查询作业提交到集群时，若集群处于“停止运行（suspended）”状态，则自动启动以执行任务。
-
-**自动停止**：在集群配置的自动停止时间内无作业/查询任务后，集群自动停止并释放计算资源，不再产生计费。
-
-### 5. 多实例弹缩
-
-Lakehouse的分析型计算集群可设定“实例最小值”和“实例最大值”，在并发请求高时自动加实例，并发请求下降后自动回收实例，满足查询业务需求的同时，节省资源成本。
-
-### 6. 计费方式
-
-按照计算集群的实际运行时间计费，精确到秒，最小计费周期1分钟。通过合理设置计算集群规格以及自动停止、自动启动等策略，可有效节省计算成本。
-
-## 三、常见使用场景与使用示例
-
-### 场景 1：离线ETL作业负载
-
-**需求**：每天或每小时执行数据清洗/转换，数据规模较大，耗时几十分钟到数小时，但在作业空闲期不希望一直空耗计算集群成本。
-**解决方案**：
-
-1\. 创建通用型计算集群
-
-在需要执行ETL作业的工作空间内，创建一个通用型计算集群。根据数据量和作业完成预期配置集群规格大小，可参考[计算集群](virtual-cluster.md)中的下表进行估算和配置：
-
-| 业务场景    | 负载类型    | 执行频率 | 作业并发 | 处理数据规模 | VCluster类型 | 作业时延SLA | VCluster 规格 |
-| ------- | ------- | ---- | ---- | ------ | ---------- | ------- | ----------- |
-| ETL调度作业 | 近实时离线处理 | 小时   | 1    | 1   TB | 通用型        | 15 分钟   | 4           |
-| ETL调度作业 | T+1离线处理 | 天    | 1    | 10 TB  | 通用型        | 4 小时    | 8           |
-
-假设需要处理的数据为10TB，预期4小时内需要完成。则需要创建一个规格为8 CRU的通用型计算集群。
-
-2\. 配置自动停止时间设置为1分钟，确保作业结束后能及时释放资源。
-
-3\. 开启“自动启动”配置，当每次ETL调度任务启动时，能够自动拉起该计算集群。
-

-
-4\. 在ETL任务（ETL\_task\_demo）的调度配置中，将任务执行的计算集群配置为上一步设置的ETL集群。更多调度配置的操作可参考[任务开发与调度](taskdevelop.md)文档中的相关内容。
-

-
-***
-
-**效果**：
-
-1\. 当ETL任务（ETL\_task\_demo）开始执行时，通用型计算集群ETL 会自动启动。
-
-2\. 当ETL任务（ETL\_task\_demo）执行结束后，通用型计算集群ETL会在空闲1分钟后自动关闭。
-
-^
-
-### 场景 2：在线报表+实时查询
-
-**需求**：每天工作时段，多个业务人员/分析师同时开始通过APP或BI进行业务查询，要求查询结果返回的延迟低、等待队列短。且为了提高资源使用效率，希望计算集群的资源消耗能够随着业务人员使用的规模动态弹缩，在无业务时能够自动关闭集群，节省成本。
-**解决方案**：
-
-1\. 创建分析型计算集群，并设置：
-
-实例规格为**4 CRU**；
-
-实例最小值为**1**，最大值为**10**；
-
-每实例的最大并发数为**8**；
-
-开启**自动启动**；
-
-自动停止时间为**30 分钟**。
-
-这样预期100GiB数据量的复杂查询，能在3秒内返回查询结果。计算集群运行时，最小规模下可以支持8并发，最大可以支持80并发的查询。超过80并发时，新增的并发请求会开始排队。超过30分钟空闲后，该计算集群将自动关闭，停止产生计算成本。关机时间延长至30分钟而非1分钟，可尽量减少频繁重启对查询体验的影响，也能保留缓存更快响应后续查询，兼顾成本和查询效果。
-
-:-: ![](.topwrite/assets/image_1743422670370.png =469)
-
-^
-
-2\. 在APP或BI链接Lakehouse执行查询作业时，配置使用ANALYTICS\_BI这个计算集群执行查询任务。以JDBC为例，连接串如下：
-
-```SQL
-jdbc:clickzetta://<your_instance_name>.<region_id>.api.clickzetta.com/<your_workspace>?username=<your_username>&password=<your_password>&virtualCluster=ANALYTICS_BI&schema=public
-```
-
-以virtualCluster=ANALYTICS\_BI参数指定执行查询任务的计算集群为ANALYTICS\_BI。
-
-**效果**：
-
-实时查询处理效率高，当用户查询量激增时，会自动扩容新实例，避免排队。保证高并发下依然有良好性能。空闲时则缩容节省成本。
-
-^
-
-### 场景 3：临时分析/数据探索
-
-**需求**：数据科学家对大规模数据做探索性分析，包括反复多表Join和高级聚合。需要能够在复杂查询时快速返回查询结果。
-**解决方案**：
-
-1\. 创建一个**大规格的分析型计算**集群，如16 CRU，提升计算并行度，缩短查询时间。实例最小值1，实例最大值2，以控制成本。
-
-:-: ![](.topwrite/assets/image_1739326621174.png =378)
-
-2\. 分析阶段可**关闭自动停止**或将自动停止时间设置成30分钟以上，保留缓存，以在反复查询时大幅提升速度。
-
-:-: ![](.topwrite/assets/image_1739326785003.png =692)
-
-^
-
-:-: ![](.topwrite/assets/image_1739327118802.png =384)
-
-3\. 分析结束后手动停止或重新缩短自动暂停时长至1分钟，以节约成本。
-
-:-: ![](.topwrite/assets/image_1739327178912.png =383)
-
-4\. 若使用中发现性能不足，可随时“手动调整”计算规格，以获得更好的查询性能。
-
-:-: ![](.topwrite/assets/image_1739327260338.png =391)
-
-**效果**：
-
-* 大规格的分析型计算集群，对大批量、复杂SQL的处理更快，分析周期更短。
-* 无需一直占用大规格资源，可随时手动调整集群规格和自动启停时间，而不影响正在进行的分析作业。
-
-^
-
-### 场景 4：多任务隔离
-
-:-: **需求**：同一部门里既有周期性ELT任务，也有Ad-Hoc分析，还有在线报表请求，希望相互之间资源不互抢、资源不浪费。
-**解决方案**：
-![](.topwrite/assets/image_1739329227325.png =709)
-
-1. 创建多个集群：
-   * **ETL专用集群**：使用通用型计算集群，根据业务使用需要，配置符合作业SLA预期的规格，自动暂停时间较短，以便作业执行完成后及时关闭集群，降低费用。可以创建多个ETL专用集群，将拥有不同SLA保障需求的ETL任务分配到不同的集群上执行，避免多个ETL任务在同一集群内争抢资源，影响重要任务的SLA。
-   * **在线报表集群**：使用分析型计算集群，启用多实例模式，使计算集群可随并发数增减而自动扩缩容，并适当延长自动停止的时间，以利用缓存提高响应速度，提供稳定的在线服务。
-   * **Ad-Hoc 分析集群**：使用分析型计算集群，配置较大规格，为复杂查询提供更好的查询性能。根据实际查询需要，在使用过程中手动调整集群规格。配置较长的自动停止时间，以保留缓存，进一步提升查询性能。
-2. 为不同的调度任务、分析查询、在线报表配置各自专用的集群，隔离不同任务的负载。
-
-**效果**：
-
-* 工作负载之间互不干扰，同时实现资源利用最大化。
-* 不同场景的SLA都能得到保障，避免“一个大作业拖慢其他全部查询”或“在线查询挤占离线任务”的情况。

-# 了解和使用Result Cache
-
-## 简介
-
-云器Lakehouse使用缓存技术来加速查询性能和效率。平台提供了三种类型的Cache来提高查询性能。
-
-1. 查询结果缓存（ Result Cache ）
-2. 元数据缓存（Metadata Cache ）
-3. 虚拟集群本地缓存（Virtual Cluster Local Disk Cache）
-
-![](.topwrite/assets/image_1713780513737.png)
-
-其中：
-
-* 元数据缓存和查询结果缓存服务从属于服务层，可在工作空间内共享。
-* 虚拟集群缓存本地缓存保存在集群本地节点，仅在使用指定虚拟集群时可以使用其本地缓存。
-
-本文中将介绍缓存的工作原理、及它们的使用方式。
-
-## 结果缓存
-
-在 云器Lakehouse 中执行查询时，会自动将符合一定条件的查询结果将保留一段时间，结果会在时间段结束后清除。这部分临时存储的的查询结果称为查询结果缓存。
-
-Result Cache需要满足以下条件才能被复用：
-
-* 查询中使用的表的基础数据不改变。如果查询中使用的任何表中的数据发生更改，则无法使用结果缓存；
-* 查询中没有包含对视图的查询。如果查询对象中包含视图，不支持保留查询结果缓存；
-* 新发起的SQL查询语句在语法上能够和先前执行过的查询精确匹配；
-* 查询中不包含非确定性函数（例如：CURRENT\_TIMESTAMP()）、用户定义函数 (UDF) ；
-* 先前的Result Cache未过期删除。
-
-## 结果缓存的过期周期
-
-结果缓存成功后，默认保留周期为24小时。
-
-在 24小时内运行使用查询结果缓存的后续查询，则结果缓存过期时间将额外延长 24 小时。否则，24小时后，查询结果缓存将被清除。
-
-## 启用与禁用结果缓存
-
-使用 cz.sql.enable.shortcut.result.cache 参数在 SESSION 级别启用或禁用，如下所示。
-
-```Python
---开启结果缓存
-set cz.sql.enable.shortcut.result.cache=true;
-
---关闭结果缓存
-set cz.sql.enable.shortcut.result.cache=false;
-```
-
-注：当前（2024年04月）Lakehouse版本的Result Cache功能处于公测阶段、未默认开启，之后版本将默认打开。
-
-## 约束与限制
-
-缓存保留周期：24小时
-
-单个工作空间支持缓存的作业数量上限：10万
-
-结果缓存大小限制：无限制。小于等于10MB的结果将缓存在管控层内存Cache，超过10MB的结果将持久化在存储层（对象存储文件）。
-
-不支持非确定性函数、UDF查询结果的结果缓存
-
-## 结果缓存演示
-
-为了演示查询结果缓存，首先启结果缓存并在云器Lakehouse中执行一个SQL查询。然后重新运行相同的查询来验证新查询是否重用了结果缓存实现加速。
-
-```Python
- --开启结果缓存
-set cz.sql.enable.shortcut.result.cache=true;
-
- select
-        l_returnflag,
-        l_linestatus,
-        sum(l_quantity) as sum_qty,
-        sum(l_extendedprice) as sum_base_price,
-        sum(l_extendedprice * (1 - l_discount)) as sum_disc_price,
-        sum(l_extendedprice * (1 - l_discount) * (1 + l_tax)) as sum_charge,
-        avg(l_quantity) as avg_qty,
-        avg(l_extendedprice) as avg_price,
-        avg(l_discount) as avg_disc,
-        count(*) as count_order
-from
-        tpch_100g_new.lineitem
-where
-        l_shipdate <= date '1998-12-01' - interval '85' day
-group by
-        l_returnflag,
-        l_linestatus
-order by
-        l_returnflag,
-        l_linestatus
-;
-```
-
-第一次执行花费了12.1秒。通过Job Profile查看作业运行信息，作业从磁盘读取了大量数据。
-
-![](.topwrite/assets/4590d8b1-4fd3-45b6-abd2-816d8ca58242.png =685)
-
-第2次执行该查询，作业复用了上次查询的结果缓存，15ms内返回结果。

-![](.topwrite/assets/383621f0-27c0-4f17-b217-0c0ad3bbc686.png)
-查看作业的Job Profile时，可在诊断页面执行计划图中看到作业使用了"JOB RESULT REUSE"，说明作业直接查询了结果数据。

-# WorkSpace（工作空间）
-
-WorkSpace（工作空间）是云器Lakehouse中用于组织和隔离资源对象（如数据对象、计算资源和用户等）的基本单元。它提供了配套的数据开发能力，包括数据集成、数据开发和数据运维等。通过使用工作空间，您可以更好地管理和控制Lakehouse中的资源和数据。
-
-## 工作空间列表
-
-登录云器Lakehouse并进入Lakehouse实例后，您可以在左侧菜单的“管理”页面中查看工作空间列表。一个服务实例下可以创建多个工作空间，它们之间默认相互隔离。用户需要加入工作空间后，才能使用其中的数据和计算资源。不同工作空间内的数据对象（如Schema、Table和View等）可以通过跨工作空间授权的方式实现数据共享。
-
-![工作空间列表截图](.topwrite/assets/image_1690451948979.png)
-
-## 创建工作空间
-
-要创建新的工作空间，请点击工作空间列表右侧的“新建”按钮。创建工作空间的用户将会默认获得该工作空间的“空间管理员”（workspace\_admin）角色，拥有使用和管理该工作空间下所有资源对象的权限，并可以管理空间内的成员。
-
-![创建工作空间截图](.topwrite/assets/image_1690452024663.png =312)
-
-## 加入工作空间
-
-只有加入工作空间的用户才能被授予相应的角色和权限，进而使用工作空间内的计算和数据资源。一个账户新建用户后，该用户初始并未加入任何工作空间，因此不具备任何工作空间的访问和使用权限。
-
-具备“空间管理员”角色的用户可以将其他用户添加到工作空间中，以便进一步授予角色和权限。空间管理员可以在“管理”-“工作空间”中点击工作空间名称进入工作空间的详情页，对工作空间中的用户进行“添加用户”和“移除用户”操作。
-
-![添加用户截图](.topwrite/assets/image_1690457600615.png)
-
-请注意，当您将用户添加到工作空间后，该用户仅加入了指定的工作空间，但尚未具备任何权限。您需要通过授予工作空间角色或权限，才能使其使用工作空间内的资源。
-
-一个用户可以同时加入多个工作空间。一个工作空间内至少需要有一名用户。
-
-## 工作空间角色
-
-为了方便快速授权，系统在每个工作空间内预设了以下空间级别的角色：
-
-| 角色名称 | 角色代码 | 角色默认权限 |
-| :--- | :--- | :--- |
-| 空间管理员 | `workspace_admin` | 拥有管理空间成员、角色、开发任务、运维中心、任务实例、空间内数据和计算集群等所有权限点的权限。 |
-| 空间成员 | `workspace_user` | 可查看空间成员、角色、开发任务、运维中心、任务实例等，但不能访问空间内数据和计算集群。 |
-| 开发人员 | `workspace_dev` | 可管理开发任务、运维中心、任务实例等，并拥有空间内数据的全部权限以及计算集群的使用权限。 |
-
-工作空间的创建者默认被授予“空间管理员”角色。其他用户在加入工作空间时，不会默认获得任何角色。一个用户可以同时被授予多个角色，其实际权限是这些角色权限的并集。一个角色可以同时授予多个用户。
-
-至少需要授予一名用户“空间管理员”角色。实例级别角色的权限与工作空间内角色的权限不存在重叠。所有工作空间内的资源均由工作空间级别的角色进行管理。用户即使被授予实例级别的任何角色，也不会直接拥有操作工作空间内对象的权限。

-# LAKEHOUSE INFORMATION\_SCHEMA元数据视图服务介绍
-
-LAKEHOUSE提供了工作空间级别的INFORMATION\_SCHEMA元数据视图服务，通过INFORMATION\_SCHEMA可查看当前空间的元数据信息及作业历史等信息。INFORMATION\_SCHEMA基于ANSI SQL-92标准设计，并扩展了云器LAKEHOUSE特有的字段和视图。它随LAKEHOUSE空间创建而默认提供，您可从中查看关心的元数据视图。
-
-## 使用说明
-
-* 视图当前阶段会存在延时15分钟左右，JOB\_HISTORY、MATERIALIZED\_VIEW刷新视图保留60天记录。
-* 最新的在线元数据信息可通过 SHOW 命令查看，例如：SHOW TABLES、SHOW JOBS 等命令将返回实时元数据信息。
-* INFORMATION\_SCHEMA下的视图均为只读，不可修改、删除。
-* 视图字段根据功能演进可能发生变化。在周期任务中使用视图时应避免使用SELECT \*直接查询所有字段，强烈建议使用SELECT COLUMN\_NAME方式选择具体需要的字段进行查询，避免视图字段发生变更时导致周期任务出错。
-
-## 权限要求
-
-* 具备workspace\_admin角色
-
-## 使用示例
-
-获取当前空间的所有表信息：
-
-```SQL
-SELECT * FROM information_schema.tables;
-```
-
-获取当前空间的所有作业信息：
-
-```SQL
-SELECT * FROM information_schema.job_history;
-```
-
-获取当前空间的所有物化视图（Materialized View）信息：
-
-```SQL
-SELECT * FROM information_schema.materialized_views;
-```
-
-## 授权操作
-
-* 由workspace\_admin角色授权的角色或用户
-
-授权给某个角色：
-
-```SQL
-GRANT ALL ON ALL VIEWS IN SCHEMA information_schema TO ROLE <role_name>;
-```
-
-授权给某个用户：
-
-```SQL
-GRANT ALL ON ALL VIEWS IN SCHEMA information_schema TO USER <user_name>;
-```
-
-## 注意事项
-
-* 请确保您已经具备了相应的权限要求，否则无法使用INFORMATION\_SCHEMA元数据视图服务。
-* 在使用INFORMATION\_SCHEMA时，请注意只读的特性，不可对视图进行修改和删除操作。
-* 请在周期任务中使用具体需要的字段进行查询，避免使用SELECT \*查询所有字段，以免因视图字段变更导致周期任务出错。

+- Run SQL queries
+- Create, manage, and schedule tasks
+- Check task run status and logs

+When the user asks operational questions about Clickzetta (e.g. listing workspaces, running SQL, checking task status), you MUST proactively use `cz-cli` via bash to take action, rather than asking the user for additional information.
 
 Run `cz-cli <command> --help` for detailed options on any command.

-You are cz-cli, the Clickzetta Studio Agent — the best data engineering coding agent on the planet.
+You are cz-cli, the ClickZetta Studio Agent. You and the user share the same workspace and collaborate to achieve the user's goals.
 
-You are an interactive CLI tool specializing in data engineering tasks. Use the instructions below and the tools available to you to assist the user.
+You are a pragmatic, effective software engineer focused on ClickZetta and data work. Communicate directly, keep momentum, and prefer accurate technical guidance over optimism or guesswork.
 
 ## Scope
-You are a specialized assistant for:
-- **ClickZetta Lakehouse & Studio**: SQL queries, task development, scheduling, data integration, metadata, lineage, DQC
-- **Data engineering**: ETL/ELT pipelines, data modeling, schema design, data quality, performance tuning
-- **Software engineering**: writing, debugging, and reviewing code in the user's current project
-- **DevOps & infrastructure**: CI/CD, deployment, monitoring related to data platforms
-
-You MUST decline questions that fall outside these domains. When a question is clearly unrelated (e.g. general trivia, personal advice, creative writing, medical/legal/financial advice, entertainment), respond with a brief one-line decline such as:
-"I'm cz-cli, focused on ClickZetta and data engineering tasks. I can't help with that, but I'm ready when you have a data or coding question."
-
-Do NOT answer general knowledge questions, math puzzles, or trivia even if they seem simple. Stay in your lane.
-
-## Business Architecture
-**Clickzetta consists of an engine layer and a data platform layer**:
-- **Engine Layer (Lakehouse)**: A data lake supporting lakehouse architecture with a SQL compute engine, containing schema, table metadata and data
-- **Data Platform Layer (Studio)**: Built on top of Lakehouse, exposing Lakehouse capabilities and providing task development, management, scheduling, data integration (import/export across engines), metadata management, data lineage, DQC, etc.
-
-## Terminology
-- "file", "task", "script", "job" all refer to **Clickzetta Task**; querying a job_id usually refers to the SQL engine's query ID
-- "directory", "folder" refer to **Clickzetta Folder**
-- Unless a specific engine type is specified, all SQL refers to Lakehouse SQL
-
-IMPORTANT: You must NEVER generate or guess URLs for the user unless you are confident that the URLs are for helping the user with programming. You may use URLs provided by the user in their messages or local files.
-
-If the user asks for help or wants to give feedback inform them of the following:
-- ctrl+p to list available actions
-
-When the user directly asks about cz-cli (eg. "can cz-cli do...", "does cz-cli have..."), or asks in second person (eg. "are you able...", "can you do..."), use available tools to help answer the question.
-
-# Tone and style
-- Only use emojis if the user explicitly requests it. Avoid using emojis in all communication unless asked.
-- Your output will be displayed on a command line interface. Your responses should be short and concise. You can use GitHub-flavored markdown for formatting, and will be rendered in a monospace font using the CommonMark specification.
-- Output text to communicate with the user; all text you output outside of tool use is displayed to the user. Only use tools to complete tasks. Never use tools like Bash or code comments as means to communicate with the user during the session.
-- NEVER create files unless they're absolutely necessary for achieving your goal. ALWAYS prefer editing an existing file to creating a new one. This includes markdown files.
-
-# Professional objectivity
-Prioritize technical accuracy and truthfulness over validating the user's beliefs. Focus on facts and problem-solving, providing direct, objective technical info without any unnecessary superlatives, praise, or emotional validation. It is best for the user if cz-cli honestly applies the same rigorous standards to all ideas and disagrees when necessary, even if it may not be what the user wants to hear. Objective guidance and respectful correction are more valuable than false agreement. Whenever there is uncertainty, it's best to investigate to find the truth first rather than instinctively confirming the user's beliefs.
-
-# Task Management
-You have access to the TodoWrite tools to help you manage and plan tasks. Use these tools VERY frequently to ensure that you are tracking your tasks and giving the user visibility into your progress.
-These tools are also EXTREMELY helpful for planning tasks, and for breaking down larger complex tasks into smaller steps. If you do not use this tool when planning, you may forget to do important tasks - and that is unacceptable.
-
-It is critical that you mark todos as completed as soon as you are done with a task. Do not batch up multiple tasks before marking them as completed.
-
-Examples:
-
-<example>
-user: Run the build and fix any type errors
-assistant: I'm going to use the TodoWrite tool to write the following items to the todo list:
-- Run the build
-- Fix any type errors
-
-I'm now going to run the build using Bash.
-
-Looks like I found 10 type errors. I'm going to use the TodoWrite tool to write 10 items to the todo list.
-
-marking the first todo as in_progress
-
-Let me start working on the first item...
-
-The first item has been fixed, let me mark the first todo as completed, and move on to the second item...
-..
-..
-</example>
-In the above example, the assistant completes all the tasks, including the 10 error fixes and running the build and fixing all errors.
-
-<example>
-user: Help me write a new feature that allows users to track their usage metrics and export them to various formats
-assistant: I'll help you implement a usage metrics tracking and export feature. Let me first use the TodoWrite tool to plan this task.
-Adding the following todos to the todo list:
-1. Research existing metrics tracking in the codebase
-2. Design the metrics collection system
-3. Implement core metrics tracking functionality
-4. Create export functionality for different formats
-
-Let me start by researching the existing codebase to understand what metrics we might already be tracking and how we can build on that.
-
-I'm going to search for any existing metrics or telemetry code in the project.
-
-I've found some existing telemetry code. Let me mark the first todo as in_progress and start designing our metrics tracking system based on what I've learned...
-
-[Assistant continues implementing the feature step by step, marking todos as in_progress and completed as they go]
-</example>
-
-
-# Doing tasks
-The user will primarily request you perform software engineering tasks. This includes solving bugs, adding new functionality, refactoring code, explaining code, and more. For these tasks the following steps are recommended:
-- 
-- Use the TodoWrite tool to plan the task if required
-
-- Tool results and user messages may include <system-reminder> tags. <system-reminder> tags contain useful information and reminders. They are automatically added by the system, and bear no direct relation to the specific tool results or user messages in which they appear.
-
-
-# Tool usage policy
-- When doing file search, prefer to use the Task tool in order to reduce context usage.
-- You should proactively use the Task tool with specialized agents when the task at hand matches the agent's description.
-
-- When WebFetch returns a message about a redirect to a different host, you should immediately make a new WebFetch request with the redirect URL provided in the response.
-- You can call multiple tools in a single response. If you intend to call multiple tools and there are no dependencies between them, make all independent tool calls in parallel. Maximize use of parallel tool calls where possible to increase efficiency. However, if some tool calls depend on previous calls to inform dependent values, do NOT call these tools in parallel and instead call them sequentially. For instance, if one operation must complete before another starts, run these operations sequentially instead. Never use placeholders or guess missing parameters in tool calls.
-- If the user specifies that they want you to run tools "in parallel", you MUST send a single message with multiple tool use content blocks. For example, if you need to launch multiple agents in parallel, send a single message with multiple Task tool calls.
-- Use specialized tools instead of bash commands when possible, as this provides a better user experience. For file operations, use dedicated tools: Read for reading files instead of cat/head/tail, Edit for editing instead of sed/awk, and Write for creating files instead of cat with heredoc or echo redirection. Reserve bash tools exclusively for actual system commands and terminal operations that require shell execution. NEVER use bash echo or other command-line tools to communicate thoughts, explanations, or instructions to the user. Output all communication directly in your response text instead.
-- VERY IMPORTANT: When exploring the codebase to gather context or to answer a question that is not a needle query for a specific file/class/function, it is CRITICAL that you use the Task tool instead of running search commands directly.
-<example>
-user: Where are errors from the client handled?
-assistant: [Uses the Task tool to find the files that handle client errors instead of using Glob or Grep directly]
-</example>
-<example>
-user: What is the codebase structure?
-assistant: [Uses the Task tool]
-</example>
-
-IMPORTANT: Always use the TodoWrite tool to plan and track tasks throughout the conversation.
-
-# Code References
-
-When referencing specific functions or pieces of code include the pattern `file_path:line_number` to allow the user to easily navigate to the source code location.
-
-<example>
-user: Where are errors from the client handled?
-assistant: Clients are marked as failed in the `connectToServer` function in src/services/process.ts:712.

+- Primary domains: ClickZetta Lakehouse and Studio, data engineering, software engineering in the current workspace, and related DevOps/infrastructure work.
+- Decline unrelated requests such as general trivia, personal advice, creative writing, or legal/medical/financial guidance.
+- When declining, keep it to one short sentence and redirect back to data or coding work.
+
+## ClickZetta context
+- ClickZetta has an engine layer and a data platform layer.
+- The engine layer is Lakehouse: SQL compute, schemas, tables, metadata, and data.
+- The platform layer is Studio: task development, scheduling, integration, metadata, lineage, DQC, and management workflows.
+- Unless the user specifies otherwise, SQL means Lakehouse SQL.
+- "file", "task", "script", and "job" usually refer to a ClickZetta Task.
+- "directory" and "folder" refer to a ClickZetta Folder.
+
+## Working style
+- Build context from the codebase before acting. Do not guess when the repo can answer the question.
+- Keep responses concise and factual. Do not use emojis unless the user explicitly asks for them.
+- Do not begin responses with filler like "Got it" or "Sure".
+- If the user asks about cz-cli itself, inspect the code or available tools before answering.
+- Never invent URLs. Only use URLs from the user, local files, or tools when you are confident they are relevant.
+- If the user wants help or feedback information, mention `ctrl+p` to list available actions.
+
+## Tool usage
+- Prefer specialized tools over shell for file operations.
+- Use `Glob` and `Grep` to find files and text.
+- Use `Read` before editing an existing file.
+- Use `Edit` for targeted changes to one file and `MultiEdit` when making several edits in the same file.
+- Use `Write` only when you need to create or fully replace a file.
+- Use `Bash` for terminal operations such as `git`, `bun`, builds, tests, and other system commands.
+- Use `TodoWrite` for non-trivial work so progress is tracked clearly.
+- Use `Task` for slash-command execution or well-scoped delegated work. Do not use it when a direct `Read`, `Glob`, or `Grep` lookup is faster.
+- When multiple tool calls are independent, make them in parallel in a single response.
+- Do not use shell commands like `cat`, `head`, `tail`, `sed`, `awk`, or `echo` when a dedicated tool is available.
+
+## Editing approach
+- Prefer the smallest correct change.
+- Follow existing patterns before introducing new structure.
+- Keep things in one function unless extraction clearly improves reuse or readability.
+- Default to ASCII when editing or creating files unless the file already relies on Unicode.
+- Add comments only when they help explain a non-obvious block.
+- Avoid creating new files unless they are clearly necessary.
+
+## Workspace hygiene
+- The worktree may already contain user changes. Never revert or overwrite changes you did not make unless the user explicitly asks.
+- If unrelated files are dirty, ignore them.
+- If the files you need are already dirty, read carefully and adapt instead of discarding existing work.
+- Avoid destructive git commands like `git reset --hard` or `git checkout --` unless the user explicitly asks.
+- Do not amend commits unless the user explicitly asks.
+
+## Execution
+- Default to doing the work instead of asking for permission.
+- Ask a question only when you are blocked by ambiguity, risk, or missing secrets that cannot be inferred safely.
+- Persist until the task is handled end-to-end when feasible: inspect, edit, verify, and report outcomes.
+- If you notice uncertainty, investigate first instead of guessing.
+
+## Output
+- Write plain text that works well in a CLI.
+- Use Markdown when it improves scanability.
+- Keep progress updates short and meaningful.
+- For code explanations or findings, include file references in the form `path/to/file.ts:42`.
+- When summarizing command results, relay the important lines instead of raw terminal dumps.

-## Frontend tasks
-When doing frontend design tasks, avoid collapsing into bland, generic layouts.
-Aim for interfaces that feel intentional and deliberate.
-- Typography: Use expressive, purposeful fonts and avoid default stacks (Inter, Roboto, Arial, system).
-- Color & Look: Choose a clear visual direction; define CSS variables; avoid purple-on-white defaults. No purple bias or dark mode bias.
-- Motion: Use a few meaningful animations (page-load, staggered reveals) instead of generic micro-motions.
-- Background: Don't rely on flat, single-color backgrounds; use gradients, shapes, or subtle patterns to build atmosphere.
-- Overall: Avoid boilerplate layouts and interchangeable UI patterns. Vary themes, type families, and visual languages across outputs.
-- Ensure the page loads properly on both desktop and mobile.

-- Default: be very concise; friendly coding teammate tone.
-- Default: do the work without asking questions. Treat short tasks as sufficient direction; infer missing details by reading the codebase and following existing conventions.
-- Questions: only ask when you are truly blocked after checking relevant context AND you cannot safely pick a reasonable default. This usually means one of:
-  * The request is ambiguous in a way that materially changes the result and you cannot disambiguate by reading the repo.
-  * The action is destructive/irreversible, touches production, or changes billing/security posture.
-  * You need a secret/credential/value that cannot be inferred (API key, account id, etc.).
-- If you must ask: do all non-blocked work first, then ask exactly one targeted question, include your recommended default, and state what would change based on the answer.
-- Never ask permission questions like "Should I proceed?" or "Do you want me to run tests?"; proceed with the most reasonable option and mention what you did.
-- For substantial work, summarize clearly; follow final‑answer formatting.
-- Skip heavy formatting for simple confirmations.
-- Don't dump large files you've written; reference paths only.
-- No "save/copy this file" - User is on the same machine.
-- Offer logical next steps (tests, commits, build) briefly; add verify steps if you couldn't do something.
-- For code changes:
-  * Lead with a quick explanation of the change, and then give more details on the context covering where and why a change was made. Do not start this explanation with "summary", just jump right in.
-  * If there are natural next steps the user may want to take, suggest them at the end of your response. Do not make suggestions if there are no natural next steps.
-  * When suggesting multiple options, use numeric lists for the suggestions so the user can quickly respond with a single number.
-- The user does not command execution outputs. When asked to show the output of a command (e.g. `git show`), relay the important details in your answer or summarize the key lines so the user understands the result.
+## Workspace hygiene
+- The worktree may already contain user changes. Never revert or overwrite changes you did not make unless the user explicitly asks.
+- If unrelated files are dirty, ignore them.
+- If the files you need are already dirty, read carefully and adapt instead of discarding existing work.
+- Avoid destructive git commands like `git reset --hard` or `git checkout --` unless the user explicitly asks.
+- Do not amend commits unless the user explicitly asks.
 
-## Final answer structure and style guidelines
+## Execution
+- Default to doing the work instead of asking for permission.
+- Ask a question only when you are blocked by ambiguity, risk, or missing secrets that cannot be inferred safely.
+- Persist until the task is handled end-to-end when feasible: inspect, edit, verify, and report outcomes.
+- If you notice uncertainty, investigate first instead of guessing.
 
-- Plain text; CLI handles styling. Use structure only when it helps scannability.
-- Headers: optional; short Title Case (1-3 words) wrapped in **…**; no blank line before the first bullet; add only if they truly help.
-- Bullets: use - ; merge related points; keep to one line when possible; 4–6 per list ordered by importance; keep phrasing consistent.
-- Monospace: backticks for commands/paths/env vars/code ids and inline examples; use for literal keyword bullets; never combine with **.
-- Code samples or multi-line snippets should be wrapped in fenced code blocks; include an info string as often as possible.
-- Structure: group related bullets; order sections general → specific → supporting; for subsections, start with a bolded keyword bullet, then items; match complexity to the task.
-- Tone: collaborative, concise, factual; present tense, active voice; self‑contained; no "above/below"; parallel wording.
-- Don'ts: no nested bullets/hierarchies; no ANSI codes; don't cram unrelated keywords; keep keyword lists short—wrap/reformat if long; avoid naming formatting styles in answers.
-- Adaptation: code explanations → precise, structured with code refs; simple tasks → lead with outcome; big changes → logical walkthrough + rationale + next actions; casual one-offs → plain sentences, no headers/bullets.
-- File References: When referencing files in your response follow the below rules:
-  * Use inline code to make file paths clickable.
-  * Each reference should have a stand alone path. Even if it's the same file.
-  * Accepted: absolute, workspace‑relative, a/ or b/ diff prefixes, or bare filename/suffix.
-  * Optionally include line/column (1‑based): :line[:column] or #Lline[Ccolumn] (column defaults to 1).
-  * Do not use URIs like file://, vscode://, or https://.
-  * Do not provide range of lines
-  * Examples: src/app.ts, src/app.ts:42, b/server/index.js#L10, C:\repo\project\main.rs:12:5
+## Output
+- Write plain text that works well in a CLI.
+- Use Markdown when it improves scanability.
+- Keep progress updates short and meaningful.
+- For code explanations or findings, include file references in the form `path/to/file.ts:42`.
+- When summarizing command results, relay the important lines instead of raw terminal dumps.

-
-          TODAY'S DATE: ${TODAY}
-
-          STEP 1: Gather today's issues
-          Search for all OPEN issues created today (${TODAY}) using:
-          gh issue list --repo ${{ github.repository }} --state open --search \"created:${TODAY}\" --json number,title,body,labels,state,comments,createdAt,author --limit 500
-
-          IMPORTANT: EXCLUDE all issues authored by Anomaly team members. Filter out issues where the author login matches ANY of these:
-          adamdotdevin, Brendonovich, fwang, Hona, iamdavidhill, jayair, kitlangton, kommander, MrMushrooooom, R44VC0RP, rekram1-node, thdxr
-          This recap is specifically for COMMUNITY (external) issues only.
-
-          STEP 2: Analyze and categorize
-          For each issue created today, categorize it:
-
-          **Severity Assessment:**
-          - CRITICAL: Crashes, data loss, security issues, blocks major functionality
-          - HIGH: Significant bugs affecting many users, important features broken
-          - MEDIUM: Bugs with workarounds, minor features broken
-          - LOW: Minor issues, cosmetic, nice-to-haves
-
-          **Activity Assessment:**
-          - Note issues with high comment counts or engagement
-          - Note issues from repeat reporters (check if author has filed before)
-
-          STEP 3: Cross-reference with existing issues
-          For issues that seem like feature requests or recurring bugs:
-          - Search for similar older issues to identify patterns
-          - Note if this is a frequently requested feature
-          - Identify any issues that are duplicates of long-standing requests
-
-          STEP 4: Generate the recap
-          Create a structured recap with these sections:
-
-          ===DISCORD_START===
-          **Daily Issues Recap - ${TODAY}**
-
-          **Summary Stats**
-          - Total issues opened today: [count]
-          - By category: [bugs/features/questions]
-
-          **Critical/High Priority Issues**
-          [List any CRITICAL or HIGH severity issues with brief descriptions and issue numbers]
-
-          **Most Active/Discussed**
-          [Issues with significant engagement or from active community members]
-
-          **Trending Topics**
-          [Patterns noticed - e.g., 'Multiple reports about X', 'Continued interest in Y feature']
-
-          **Duplicates & Related**
-          [Issues that relate to existing open issues]
-          ===DISCORD_END===
-
-          STEP 5: Format for Discord
-          Format the recap as a Discord-compatible message:
-          - Use Discord markdown (**, __, etc.)
-          - BE EXTREMELY CONCISE - this is an EOD summary, not a detailed report
-          - Use hyperlinked issue numbers with suppressed embeds: [#1234](<https://github.com/${{ github.repository }}/issues/1234>)
-          - Group related issues on single lines where possible
-          - Add emoji sparingly for critical items only
-          - HARD LIMIT: Keep under 1800 characters total
-          - Skip sections that have nothing notable (e.g., if no critical issues, omit that section)
-          - Prioritize signal over completeness - only surface what matters
-
-          OUTPUT: Output ONLY the content between ===DISCORD_START=== and ===DISCORD_END=== markers. Include the markers so I can extract it." > /tmp/recap_raw.txt
-

-
-          TODAY'S DATE: ${TODAY}
-
-          STEP 1: Gather PR data
-          Run these commands to gather PR information. ONLY include OPEN PRs created or updated TODAY (${TODAY}):
-
-          # Open PRs created today
-          gh pr list --repo ${{ github.repository }} --state open --search \"created:${TODAY}\" --json number,title,author,labels,createdAt,updatedAt,reviewDecision,isDraft,additions,deletions --limit 100
-
-          # Open PRs with activity today (updated today)
-          gh pr list --repo ${{ github.repository }} --state open --search \"updated:${TODAY}\" --json number,title,author,labels,createdAt,updatedAt,reviewDecision,isDraft,additions,deletions --limit 100
-
-          IMPORTANT: EXCLUDE all PRs authored by Anomaly team members. Filter out PRs where the author login matches ANY of these:
-          adamdotdevin, Brendonovich, fwang, Hona, iamdavidhill, jayair, kitlangton, kommander, MrMushrooooom, R44VC0RP, rekram1-node, thdxr
-          This recap is specifically for COMMUNITY (external) contributions only.
-
-
-
-          STEP 2: For high-activity PRs, check comment counts
-          For promising PRs, run:
-          gh pr view [NUMBER] --repo ${{ github.repository }} --json comments --jq '[.comments[] | select(.author.login != \"copilot-pull-request-reviewer\" and .author.login != \"github-actions\")] | length'
-
-          IMPORTANT: When counting comments/activity, EXCLUDE these bot accounts:
-          - copilot-pull-request-reviewer
-          - github-actions
-
-          STEP 3: Identify what matters (ONLY from today's PRs)
-
-          **Bug Fixes From Today:**
-          - PRs with 'fix' or 'bug' in title created/updated today
-          - Small bug fixes (< 100 lines changed) that are easy to review
-          - Bug fixes from community contributors
-
-          **High Activity Today:**
-          - PRs with significant human comments today (excluding bots listed above)
-          - PRs with back-and-forth discussion today
-
-          **Quick Wins:**
-          - Small PRs (< 50 lines) that are approved or nearly approved
-          - PRs that just need a final review
-
-          STEP 4: Generate the recap
-          Create a structured recap:
-
-          ===DISCORD_START===
-          **Daily PR Recap - ${TODAY}**
-
-          **New PRs Today**
-          [PRs opened today - group by type: bug fixes, features, etc.]
-
-          **Active PRs Today**
-          [PRs with activity/updates today - significant discussion]
-
-          **Quick Wins**
-          [Small PRs ready to merge]
-          ===DISCORD_END===
-
-          STEP 5: Format for Discord
-          - Use Discord markdown (**, __, etc.)
-          - BE EXTREMELY CONCISE - surface what we might miss
-          - Use hyperlinked PR numbers with suppressed embeds: [#1234](<https://github.com/${{ github.repository }}/pull/1234>)
-          - Include PR author: [#1234](<url>) (@author)
-          - For bug fixes, add brief description of what it fixes
-          - Show line count for quick wins: \"(+15/-3 lines)\"
-          - HARD LIMIT: Keep under 1800 characters total
-          - Skip empty sections
-          - Focus on PRs that need human eyes
-
-          OUTPUT: Output ONLY the content between ===DISCORD_START=== and ===DISCORD_END=== markers. Include the markers so I can extract it." > /tmp/pr_recap_raw.txt
-
-          # Extract only the Discord message between markers
-          sed -n '/===DISCORD_START===/,/===DISCORD_END===/p' /tmp/pr_recap_raw.txt | grep -v '===DISCORD' > /tmp/pr_recap.txt

-            3. Do not translate directly in the primary agent. Use translator subagent output as the source for locale text updates.
-            4. Run translator subagent Task calls in parallel whenever file/locale translation work is independent.
-            5. Use only the minimum tools needed for this task (read/glob, file edits, and translator Task). Do not use shell, web, search, or GitHub tools for translation work.
-            6. Preserve frontmatter keys, internal links, code blocks, and existing locale-specific metadata unless the English change requires an update.
-            7. Keep locale docs structure aligned with their corresponding English pages.
-            8. Do not modify English source docs in packages/web/src/content/docs/*.mdx.
-            9. If no locale updates are needed, make no changes.

-
-            Steps:
-            1. For each commit that looks like a new feature or significant change:
-               - Read the changed files to understand what was added
-               - Check if the feature is already documented in packages/web/src/content/docs/*
-            2. If you find undocumented features:
-               - Update the relevant documentation files in packages/web/src/content/docs/*
-               - Follow the existing documentation style and structure
-               - Make sure to document the feature clearly with examples where appropriate
-            3. If all new features are already documented, report that no updates are needed
-            4. If you are creating a new documentation file be sure to update packages/web/astro.config.mjs too.

-            Focus on user-facing features and API changes. Skip internal refactors, bug fixes, and test updates unless they affect user-facing behavior.
-            Don't feel the need to document every little thing. It is perfectly okay to make 0 changes at all.
-            Try to keep documentation only for large features or changes that already have a good spot to be documented.

-          Lookup this issue with gh issue view ${{ github.event.issue.number }}.
-
-          You have TWO tasks. Perform both, then post a SINGLE comment (if needed).
-
-          ---
-
-          TASK 1: CONTRIBUTING GUIDELINES COMPLIANCE CHECK
-
-          Check whether the issue follows our contributing guidelines and issue templates.
-
-          This project has three issue templates that every issue MUST use one of:
-
-          1. Bug Report - requires a Description field with real content
-          2. Feature Request - requires a verification checkbox and description, title should start with [FEATURE]:
-          3. Question - requires the Question field with real content
-
-          Additionally check:
-          - No AI-generated walls of text (long, AI-generated descriptions are not acceptable)
-          - The issue has real content, not just template placeholder text left unchanged
-          - Bug reports should include some context about how to reproduce
-          - Feature requests should explain the problem or need
-          - We want to push for having the user provide system description & information
-
-          Do NOT be nitpicky about optional fields. Only flag real problems like: no template used, required fields empty or placeholder text only, obviously AI-generated walls of text, or completely empty/nonsensical content.
-
-          ---
-
-          TASK 2: DUPLICATE CHECK
-
-          Search through existing issues (excluding #${{ github.event.issue.number }}) to find potential duplicates.
-          Consider:
-          1. Similar titles or descriptions
-          2. Same error messages or symptoms
-          3. Related functionality or components
-          4. Similar feature requests
-
-          Additionally, if the issue mentions keybinds, keyboard shortcuts, or key bindings, note the pinned keybinds issue #4997.
-
-          ---
-
-          POSTING YOUR COMMENT:
-
-          Based on your findings, post a SINGLE comment on issue #${{ github.event.issue.number }}. Build the comment as follows:
-
-          If the issue is NOT compliant, start the comment with:
-          <!-- issue-compliance -->
-          Then explain what needs to be fixed and that they have 2 hours to edit the issue before it is automatically closed. Also add the label needs:compliance to the issue using: gh issue edit ${{ github.event.issue.number }} --add-label needs:compliance
-
-          If duplicates were found, include a section about potential duplicates with links.
-
-          If the issue mentions keybinds/keyboard shortcuts, include a note about #4997.
-
-          If the issue IS compliant AND no duplicates were found AND no keybind reference, do NOT comment at all.
-
-          Use this format for the comment:
-
-          [If not compliant:]
-          <!-- issue-compliance -->
-          This issue doesn't fully meet our [contributing guidelines](../blob/dev/CONTRIBUTING.md).
-
-          **What needs to be fixed:**
-          - [specific reasons]
-
-          Please edit this issue to address the above within **2 hours**, or it will be automatically closed.
-
-          [If duplicates found, add:]
-          ---
-          This issue might be a duplicate of existing issues. Please check:
-          - #[issue_number]: [brief description of similarity]
-
-          [If keybind-related, add:]
-          For keybind-related issues, please also check our pinned keybinds documentation: #4997
-
-          [End with if not compliant:]
-          If you believe this was flagged incorrectly, please let a maintainer know.
-
-          Remember: post at most ONE comment combining all findings. If everything is fine, post nothing."

-
-          If the issue is NOW compliant:
-          1. Remove the needs:compliance label: gh issue edit ${{ github.event.issue.number }} --remove-label needs:compliance
-          2. Find and delete the previous compliance comment (the one containing <!-- issue-compliance -->) using: gh api repos/${{ github.repository }}/issues/${{ github.event.issue.number }}/comments --jq '.[] | select(.body | contains(\"<!-- issue-compliance -->\")) | .id' then delete it with: gh api -X DELETE repos/${{ github.repository }}/issues/${{ github.event.issue.number }}/comments/{id}
-          3. Post a short comment thanking them for updating the issue.
-
-          If the issue is STILL not compliant:
-          Post a comment explaining what still needs to be fixed. Keep the needs:compliance label."

-          Please check all the code changes in this pull request against the style guide, also look for any bugs if they exist. Diffs are important but make sure you read the entire file to get proper context. Make it clear the suggestions are merely suggestions and the human can decide what to do
-
-          When critiquing code against the style guide, be sure that the code is ACTUALLY in violation, don't complain about else statements if they already use early returns there. You may complain about excessive nesting though, regardless of else statement usage.
-          When critiquing code style don't be a zealot, we don't like "let" statements but sometimes they are the simplest option, if someone does a bunch of nesting with let, they should consider using iife (see packages/opencode/src/util.iife.ts)
-
-          Use the gh cli to create comments on the files for the violations. Try to leave the comment on the exact line number. If you have a suggested fix include it in a suggestion code block.
-          If you are writing suggested fixes, BE SURE THAT the change you are recommending is actually valid typescript, often I have seen missing closing "}" or other syntax errors.
-          Generally, write a comment instead of writing suggested change if you can help it.
-
-          Command MUST be like this.
-          \`\`\`
-          gh api \
-            --method POST \
-            -H \"Accept: application/vnd.github+json\" \

-          \`\`\`
-
-          Only create comments for actual violations. If the code follows all guidelines, comment on the issue using gh cli: 'lgtm' AND NOTHING ELSE!!!!."

Subject: [PATCH 258/521] fix(cli): route `--session` flag correctly to agent
 runtime

AGENT_FLAGS_WITH_VALUES had `-s` but not `--session`, so
`cz-cli agent --session <id>` misrouted the session ID as a
subcommand name and failed with a USAGE_ERROR.

Subject: [PATCH 261/521] fix(cli): make `run` async by default in non-TTY or
 a2a format

Previously async mode required both non-TTY AND --format a2a/json.
Now non-TTY alone or --format a2a alone triggers async submission,
which is the expected behavior for subagent invocations.

Subject: [PATCH 262/521] refactor(cli): remove --format a2a, simplify async
 behavior
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Async mode is now triggered by non-TTY or explicit --async, independent
of output format. The a2a format was redundant — async already returns
{session_id, status} which is all callers need.

 ### AI Subagent Invocation
 
-AI agents call cz-cli with structured output via the `--format a2a` flag:
+AI agents call cz-cli in non-TTY environments, which automatically runs asynchronously:
 
 ```bash
-cz-cli agent run "<request>" --format a2a --dangerously-skip-permissions
+cz-cli agent run "<request>" --dangerously-skip-permissions
 ```
 
 Use `--session <id>` for multi-turn conversations on the same topic.

 /**
- * `cz-cli update` — manually update cz-cli to the latest version.
+ * `cz-cli update` — update cz-cli to the latest version via cz-cli.ai/install.sh.
  *
- * Detection flow:
- * 1. Check if npm global has the package
- * 2. Check if bun global has the package
- * 3. If both → error, ask user to uninstall one
- * 4. If one → use that package manager to update
- * 5. If neither → clean up stale binaries via `which`, then install via npm
+ * Flow:
+ * 1. Fetch latest version from cz-cli.ai/api/stable (fallback: npm registry)
+ * 2. Detect & clean up stale/conflicting binaries
+ * 3. Perform upgrade via install script or package manager

Subject: [PATCH 267/521] fix(ci): re-enable Linux release builds
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Linux users cannot update because COS has no linux-x64/linux-arm64
binaries — the CI matrix and npm publish pipeline had Linux commented
out. Re-enable ubuntu-latest and ubuntu-24.04-arm runners, add
linux-x64/linux-arm64 to npm PLATFORMS array, SUPPORTED_PACKAGES set,
and optionalDependencies.

Subject: [PATCH 268/521] fix(sql): prevent duplicate output for write
 operations

emitResult() was missing a return after success() for write ops,
causing a second successRows() call that emitted an extra empty JSON line.

Subject: [PATCH 270/521] feat(cz-cli): add gateway command for AI Gateway
 virtual keys

Add `cz-cli gateway` with key list/create/get/set-quota/enable/disable/delete
and model list subcommands, backed by the /llm-gateway-admin/v2 admin APIs via
studioRequest.

- resolveKeyId reverse-looks up the numeric id from a vApiKey via list
- key create supports routing rules and a default total quota (10,000,000),
  with --add-to-llm to register the key as a [llm.*] entry for the agent
- set-quota does a non-overwriting single-quota update
- add getGatewayContext (tenant-scoped, no workspace resolution) for these
  account-level APIs

Subject: [PATCH 271/521] fix: --with-schema extracts column types from query
 result metadata

Use r.columns (ColumnSchema[]) directly from the query result instead of
running a separate DESC TABLE query. Works for any SQL including expressions
without table references.

-# Contributing to OpenCode
-
-We want to make it easy for you to contribute to OpenCode. Here are the most common type of changes that get merged:
-
-- Bug fixes
-- Additional LSPs / Formatters
-- Improvements to LLM performance
-- Support for new providers
-- Fixes for environment-specific quirks
-- Missing standard behavior
-- Documentation improvements
-
-However, any UI or core product feature must go through a design review with the core team before implementation.
-
-If you are unsure if a PR would be accepted, feel free to ask a maintainer or look for issues with any of the following labels:
-
-- [`help wanted`](https://github.com/anomalyco/opencode/issues?q=is%3Aissue%20state%3Aopen%20label%3Ahelp-wanted)
-- [`good first issue`](https://github.com/anomalyco/opencode/issues?q=is%3Aissue%20state%3Aopen%20label%3A%22good%20first%20issue%22)
-- [`bug`](https://github.com/anomalyco/opencode/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug)
-- [`perf`](https://github.com/anomalyco/opencode/issues?q=is%3Aopen%20is%3Aissue%20label%3A%22perf%22)
-
-> [!NOTE]
-> PRs that ignore these guardrails will likely be closed.
-
-Want to take on an issue? Leave a comment and a maintainer may assign it to you unless it is something we are already working on.
-
-## Adding New Providers
-
-New providers shouldn't require many if ANY code changes, but if you want to add support for a new provider first make a PR to:
-https://github.com/anomalyco/models.dev
-
-## Developing OpenCode
-
-- Requirements: Bun 1.3+
-- Install dependencies and start the dev server from the repo root:
-
-  ```bash
-  bun install
-  bun dev
-  ```
-
-### Running against a different directory
-
-By default, `bun dev` runs OpenCode in the `packages/opencode` directory. To run it against a different directory or repository:
-
-```bash
-bun dev <directory>
-```
-
-To run OpenCode in the root of the opencode repo itself:
-
-```bash
-bun dev .
-```
-
-### Building a "localcode"
-
-To compile a standalone executable:
-
-```bash
-./packages/opencode/script/build.ts --single
-```
-
-Then run it with:
-
-```bash
-./packages/opencode/dist/opencode-<platform>/bin/opencode
-```
-
-Replace `<platform>` with your platform (e.g., `darwin-arm64`, `linux-x64`).
-
-- Core pieces:
-  - `packages/opencode`: OpenCode core business logic & server.
-  - `packages/opencode/src/cli/cmd/tui/`: The TUI code, written in SolidJS with [opentui](https://github.com/sst/opentui)
-  - `packages/app`: The shared web UI components, written in SolidJS
-  - `packages/desktop`: The native desktop app, built with Tauri (wraps `packages/app`)
-  - `packages/plugin`: Source for `@opencode-ai/plugin`
-
-### Understanding bun dev vs opencode
-
-During development, `bun dev` is the local equivalent of the built `opencode` command. Both run the same CLI interface:
-
-```bash
-# Development (from project root)
-bun dev --help           # Show all available commands
-bun dev serve            # Start headless API server
-bun dev web              # Start server + open web interface
-bun dev <directory>      # Start TUI in specific directory
-
-# Production
-opencode --help          # Show all available commands
-opencode serve           # Start headless API server
-opencode web             # Start server + open web interface
-opencode <directory>     # Start TUI in specific directory
-```
-
-### Running the API Server
-
-To start the OpenCode headless API server:
-
-```bash
-bun dev serve
-```
-
-This starts the headless server on port 4096 by default. You can specify a different port:
-
-```bash
-bun dev serve --port 8080
-```
-
-### Running the Web App
-
-To test UI changes during development:
-
-1. **First, start the OpenCode server** (see [Running the API Server](#running-the-api-server) section above)
-2. **Then run the web app:**
-
-```bash
-bun run --cwd packages/app dev
-```
-
-This starts a local dev server at http://localhost:5173 (or similar port shown in output). Most UI changes can be tested here, but the server must be running for full functionality.
-
-### Running the Desktop App
-
-The desktop app is a native Tauri application that wraps the web UI.
-
-To run the native desktop app:
-
-```bash
-bun run --cwd packages/desktop tauri dev
-```
-
-This starts the web dev server on http://localhost:1420 and opens the native window.
-
-If you only want the web dev server (no native shell):
-
-```bash
-bun run --cwd packages/desktop dev
-```
-
-To create a production `dist/` and build the native app bundle:
-
-```bash
-bun run --cwd packages/desktop tauri build
-```
-
-This runs `bun run --cwd packages/desktop build` automatically via Tauri’s `beforeBuildCommand`.
-
-> [!NOTE]
-> Running the desktop app requires additional Tauri dependencies (Rust toolchain, platform-specific libraries). See the [Tauri prerequisites](https://v2.tauri.app/start/prerequisites/) for setup instructions.
-
-> [!NOTE]
-> If you make changes to the API or SDK (e.g. `packages/opencode/src/server/server.ts`), run `./script/generate.ts` to regenerate the SDK and related files.
-
-Please try to follow the [style guide](./AGENTS.md)
-
-### Setting up a Debugger
-
-Bun debugging is currently rough around the edges. We hope this guide helps you get set up and avoid some pain points.
-
-The most reliable way to debug OpenCode is to run it manually in a terminal via `bun run --inspect=<url> dev ...` and attach
-your debugger via that URL. Other methods can result in breakpoints being mapped incorrectly, at least in VSCode (YMMV).
-
-Caveats:
-
-- If you want to run the OpenCode TUI and have breakpoints triggered in the server code, you might need to run `bun dev spawn` instead of
-  the usual `bun dev`. This is because `bun dev` runs the server in a worker thread and breakpoints might not work there.
-- If `spawn` does not work for you, you can debug the server separately:
-  - Debug server: `bun run --inspect=ws://localhost:6499/ --cwd packages/opencode ./src/index.ts serve --port 4096`,
-    then attach TUI with `opencode attach http://localhost:4096`
-  - Debug TUI: `bun run --inspect=ws://localhost:6499/ --cwd packages/opencode --conditions=browser ./src/index.ts`
-
-Other tips and tricks:
-
-- You might want to use `--inspect-wait` or `--inspect-brk` instead of `--inspect`, depending on your workflow
-- Specifying `--inspect=ws://localhost:6499/` on every invocation can be tiresome, you may want to `export BUN_OPTIONS=--inspect=ws://localhost:6499/` instead
-
-#### VSCode Setup
-
-If you use VSCode, you can use our example configurations [.vscode/settings.example.json](.vscode/settings.example.json) and [.vscode/launch.example.json](.vscode/launch.example.json).
-
-Some debug methods that can be problematic:
-
-- Debug configurations with `"request": "launch"` can have breakpoints incorrectly mapped and thus unusable
-- The same problem arises when running OpenCode in the VSCode `JavaScript Debug Terminal`
-
-With that said, you may want to try these methods, as they might work for you.
-
-## Pull Request Expectations
-
-### Issue First Policy
-
-**All PRs must reference an existing issue.** Before opening a PR, open an issue describing the bug or feature. This helps maintainers triage and prevents duplicate work. PRs without a linked issue may be closed without review.
-
-- Use `Fixes #123` or `Closes #123` in your PR description to link the issue
-- For small fixes, a brief issue is fine - just enough context for maintainers to understand the problem
-
-### General Requirements
-
-- Keep pull requests small and focused
-- Explain the issue and why your change fixes it
-- Before adding new functionality, ensure it doesn't already exist elsewhere in the codebase
-
-### UI Changes
-
-If your PR includes UI changes, please include screenshots or videos showing the before and after. This helps maintainers review faster and gives you quicker feedback.
-
-### Logic Changes
-
-For non-UI changes (bug fixes, new features, refactors), explain **how you verified it works**:
-
-- What did you test?
-- How can a reviewer reproduce/confirm the fix?
-
-### No AI-Generated Walls of Text
-
-Long, AI-generated PR descriptions and issues are not acceptable and may be ignored. Respect the maintainers' time:
-
-- Write short, focused descriptions
-- Explain what changed and why in your own words
-- If you can't explain it briefly, your PR might be too large
-
-### PR Titles
-
-PR titles should follow conventional commit standards:
-
-- `feat:` new feature or functionality
-- `fix:` bug fix
-- `docs:` documentation or README changes
-- `chore:` maintenance tasks, dependency updates, etc.
-- `refactor:` code refactoring without changing behavior
-- `test:` adding or updating tests
-
-You can optionally include a scope to indicate which package is affected:
-
-- `feat(app):` feature in the app package
-- `fix(desktop):` bug fix in the desktop package
-- `chore(opencode):` maintenance in the opencode package
-
-Examples:
-
-- `docs: update contributing guidelines`
-- `fix: resolve crash on startup`
-- `feat: add dark mode support`
-- `feat(app): add dark mode support`
-- `fix(desktop): resolve crash on startup`
-- `chore: bump dependency versions`
-
-### Style Preferences
-
-These are not strictly enforced, they are just general guidelines:
-
-- **Functions:** Keep logic within a single function unless breaking it out adds clear reuse or composition benefits.
-- **Destructuring:** Do not do unnecessary destructuring of variables.
-- **Control flow:** Avoid `else` statements.
-- **Error handling:** Prefer `.catch(...)` instead of `try`/`catch` when possible.
-- **Types:** Reach for precise types and avoid `any`.
-- **Variables:** Stick to immutable patterns and avoid `let`.
-- **Naming:** Choose concise single-word identifiers when they remain descriptive.
-- **Runtime APIs:** Use Bun helpers such as `Bun.file()` when they fit the use case.
-
-## Feature Requests
-
-For net-new functionality, start with a design conversation. Open an issue describing the problem, your proposed approach (optional), and why it belongs in OpenCode. The core team will help decide whether it should move forward; please wait for that approval instead of opening a feature PR directly.
-
-## Trust & Vouch System
-
-This project uses [vouch](https://github.com/mitchellh/vouch) to manage contributor trust. The vouch list is maintained in [`.github/VOUCHED.td`](.github/VOUCHED.td).
-
-### How it works
-
-- **Vouched users** are explicitly trusted contributors.
-- **Denounced users** are explicitly blocked. Issues and pull requests from denounced users are automatically closed. If you have been denounced, you can request to be unvouched by reaching out to a maintainer on [Discord](https://opencode.ai/discord)
-- **Everyone else** can participate normally — you don't need to be vouched to open issues or PRs.
-
-### For maintainers
-
-Collaborators with write access can manage the vouch list by commenting on any issue:
-
-- `vouch` — vouch for the issue author
-- `vouch @username` — vouch for a specific user
-- `denounce` — denounce the issue author
-- `denounce @username` — denounce a specific user
-- `denounce @username <reason>` — denounce with a reason
-- `unvouch` / `unvouch @username` — remove someone from the list
-
-Changes are committed automatically to `.github/VOUCHED.td`.
-
-### Denouncement policy
-
-Denouncement is reserved for users who repeatedly submit low-quality AI-generated contributions, spam, or otherwise act in bad faith. It is not used for disagreements or honest mistakes.
-
-## Issue Requirements
-
-All issues **must** use one of our issue templates:
-
-- **Bug report** — for reporting bugs (requires a description)
-- **Feature request** — for suggesting enhancements (requires verification checkbox and description)
-- **Question** — for asking questions (requires the question)
-
-Blank issues are not allowed. When a new issue is opened, an automated check verifies that it follows a template and meets our contributing guidelines. If an issue doesn't meet the requirements, you'll receive a comment explaining what needs to be fixed and have **2 hours** to edit the issue. After that, it will be automatically closed.
-
-Issues may be flagged for:
-
-- Not using a template
-- Required fields left empty or filled with placeholder text
-- AI-generated walls of text
-- Missing meaningful content
-
-If you believe your issue was incorrectly flagged, let a maintainer know.

-
-يحترم سكربت التثبيت ترتيب الاولوية التالي لمسار التثبيت:
-
-1. `$OPENCODE_INSTALL_DIR` - مجلد تثبيت مخصص
-2. `$XDG_BIN_DIR` - مسار متوافق مع مواصفات XDG Base Directory
-3. `$HOME/bin` - مجلد الثنائيات القياسي للمستخدم (ان وجد او امكن انشاؤه)
-4. `$HOME/.opencode/bin` - المسار الافتراضي الاحتياطي
-
-```bash
-# امثلة
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Agents
-
-يتضمن OpenCode وكيليْن (Agents) مدمجين يمكنك التبديل بينهما باستخدام زر `Tab`.
-
-- **build** - الافتراضي، وكيل بصلاحيات كاملة لاعمال التطوير
-- **plan** - وكيل للقراءة فقط للتحليل واستكشاف الكود
-  - يرفض تعديل الملفات افتراضيا
-  - يطلب الاذن قبل تشغيل اوامر bash
-  - مثالي لاستكشاف قواعد كود غير مألوفة او لتخطيط التغييرات
-
-بالاضافة الى ذلك يوجد وكيل فرعي **general** للبحث المعقد والمهام متعددة الخطوات.
-يستخدم داخليا ويمكن استدعاؤه بكتابة `@general` في الرسائل.
-
-تعرف على المزيد حول [agents](https://opencode.ai/docs/agents).
-
-### التوثيق
-
-لمزيد من المعلومات حول كيفية ضبط OpenCode، [**راجع التوثيق**](https://opencode.ai/docs).
-
-### المساهمة
-
-اذا كنت مهتما بالمساهمة في OpenCode، يرجى قراءة [contributing docs](./CONTRIBUTING.md) قبل ارسال pull request.
-
-### البناء فوق OpenCode
-
-اذا كنت تعمل على مشروع مرتبط بـ OpenCode ويستخدم "opencode" كجزء من اسمه (مثل "opencode-dashboard" او "opencode-mobile")، يرجى اضافة ملاحظة في README توضح انه ليس مبنيا بواسطة فريق OpenCode ولا يرتبط بنا بأي شكل.
-
-### FAQ
-
-#### ما الفرق عن Claude Code؟
-
-هو مشابه جدا لـ Claude Code من حيث القدرات. هذه هي الفروقات الاساسية:
-
-- 100% مفتوح المصدر
-- غير مقترن بمزود معين. نوصي بالنماذج التي نوفرها عبر [OpenCode Zen](https://opencode.ai/zen)؛ لكن يمكن استخدام OpenCode مع Claude او OpenAI او Google او حتى نماذج محلية. مع تطور النماذج ستتقلص الفجوات وستنخفض الاسعار، لذا من المهم ان يكون مستقلا عن المزود.
-- دعم LSP جاهز للاستخدام
-- تركيز على TUI. تم بناء OpenCode بواسطة مستخدمي neovim ومنشئي [terminal.shop](https://terminal.shop)؛ وسندفع حدود ما هو ممكن داخل الطرفية.
-- معمارية عميل/خادم. على سبيل المثال، يمكن تشغيل OpenCode على جهازك بينما تقوده عن بعد من تطبيق جوال. هذا يعني ان واجهة TUI هي واحدة فقط من العملاء الممكنين.

-
-### এজেন্টস (Agents)
-
-OpenCode এ দুটি বিল্ট-ইন এজেন্ট রয়েছে যা আপনি `Tab` কি(key) দিয়ে পরিবর্তন করতে পারবেন।
-
-- **build** - ডিফল্ট, ডেভেলপমেন্টের কাজের জন্য সম্পূর্ণ অ্যাক্সেসযুক্ত এজেন্ট
-- **plan** - বিশ্লেষণ এবং কোড এক্সপ্লোরেশনের জন্য রিড-ওনলি এজেন্ট
-  - ডিফল্টভাবে ফাইল এডিট করতে দেয় না
-  - ব্যাশ কমান্ড চালানোর আগে অনুমতি চায়
-  - অপরিচিত কোডবেস এক্সপ্লোর করা বা পরিবর্তনের পরিকল্পনা করার জন্য আদর্শ
-
-এছাড়াও জটিল অনুসন্ধান এবং মাল্টিস্টেপ টাস্কের জন্য একটি **general** সাবএজেন্ট অন্তর্ভুক্ত রয়েছে।
-এটি অভ্যন্তরীণভাবে ব্যবহৃত হয় এবং মেসেজে `@general` লিখে ব্যবহার করা যেতে পারে।
-
-এজেন্টদের সম্পর্কে আরও জানুন: [docs](https://opencode.ai/docs/agents)।
-
-### ডকুমেন্টেশন (Documentation)
-
-কিভাবে OpenCode কনফিগার করবেন সে সম্পর্কে আরও তথ্যের জন্য, [**আমাদের ডকস দেখুন**](https://opencode.ai/docs)।
-
-### অবদান (Contributing)
-
-আপনি যদি OpenCode এ অবদান রাখতে চান, অনুগ্রহ করে একটি পুল রিকোয়েস্ট সাবমিট করার আগে আমাদের [কন্ট্রিবিউটিং ডকস](./CONTRIBUTING.md) পড়ে নিন।
-
-### OpenCode এর উপর বিল্ডিং (Building on OpenCode)
-
-আপনি যদি এমন প্রজেক্টে কাজ করেন যা OpenCode এর সাথে সম্পর্কিত এবং প্রজেক্টের নামের অংশ হিসেবে "opencode" ব্যবহার করেন, উদাহরণস্বরূপ "opencode-dashboard" বা "opencode-mobile", তবে দয়া করে আপনার README তে একটি নোট যোগ করে স্পষ্ট করুন যে এই প্রজেক্টটি OpenCode দল দ্বারা তৈরি হয়নি এবং আমাদের সাথে এর কোনো সরাসরি সম্পর্ক নেই।
-
-### সচরাচর জিজ্ঞাসিত প্রশ্নাবলী (FAQ)
-
-#### এটি ক্লড কোড (Claude Code) থেকে কীভাবে আলাদা?
-
-ক্যাপাবিলিটির দিক থেকে এটি ক্লড কোডের (Claude Code) মতই। এখানে মূল পার্থক্যগুলো দেওয়া হলো:
-
-- ১০০% ওপেন সোর্স
-- কোনো প্রোভাইডারের সাথে আবদ্ধ নয়। যদিও আমরা [OpenCode Zen](https://opencode.ai/zen) এর মাধ্যমে মডেলসমূহ ব্যবহারের পরামর্শ দিই, OpenCode ক্লড (Claude), ওপেনএআই (OpenAI), গুগল (Google), অথবা লোকাল মডেলগুলোর সাথেও ব্যবহার করা যেতে পারে। যেমন যেমন মডেলগুলো উন্নত হবে, তাদের মধ্যকার পার্থক্য কমে আসবে এবং দামও কমবে, তাই প্রোভাইডার-অজ্ঞাস্টিক হওয়া খুবই গুরুত্বপূর্ণ।
-- আউট-অফ-দ্য-বক্স LSP সাপোর্ট
-- TUI এর উপর ফোকাস। OpenCode নিওভিম (neovim) ব্যবহারকারী এবং [terminal.shop](https://terminal.shop) এর নির্মাতাদের দ্বারা তৈরি; আমরা টার্মিনালে কী কী সম্ভব তার সীমাবদ্ধতা ছাড়িয়ে যাওয়ার চেষ্টা করছি।
-- ক্লায়েন্ট/সার্ভার আর্কিটেকচার। এটি যেমন OpenCode কে আপনার কম্পিউটারে চালানোর সুযোগ দেয়, তেমনি আপনি মোবাইল অ্যাপ থেকে রিমোটলি এটি নিয়ন্ত্রণ করতে পারবেন, অর্থাৎ TUI ফ্রন্টএন্ড কেবল সম্ভাব্য ক্লায়েন্টগুলোর মধ্যে একটি।

-
-### App desktop (BETA)
-
-O OpenCode também está disponível como aplicativo desktop. Baixe diretamente pela [página de releases](https://github.com/anomalyco/opencode/releases) ou em [opencode.ai/download](https://opencode.ai/download).
-
-| Plataforma            | Download                              |
-| --------------------- | ------------------------------------- |
-| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |
-| macOS (Intel)         | `opencode-desktop-darwin-x64.dmg`     |
-| Windows               | `opencode-desktop-windows-x64.exe`    |

-# macOS (Homebrew)
-brew install --cask opencode-desktop
-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
-```
-
-#### Diretório de instalação
-
-O script de instalação respeita a seguinte ordem de prioridade para o caminho de instalação:
-
-1. `$OPENCODE_INSTALL_DIR` - Diretório de instalação personalizado
-2. `$XDG_BIN_DIR` - Caminho compatível com a especificação XDG Base Directory
-3. `$HOME/bin` - Diretório binário padrão do usuário (se existir ou puder ser criado)
-4. `$HOME/.opencode/bin` - Fallback padrão
-
-```bash
-# Exemplos
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Agents
-
-O OpenCode inclui dois agents integrados, que você pode alternar com a tecla `Tab`.
-
-- **build** - Padrão, agent com acesso total para trabalho de desenvolvimento
-- **plan** - Agent somente leitura para análise e exploração de código
-  - Nega edições de arquivos por padrão
-  - Pede permissão antes de executar comandos bash
-  - Ideal para explorar codebases desconhecidas ou planejar mudanças
-
-Também há um subagent **general** para buscas complexas e tarefas em várias etapas.
-Ele é usado internamente e pode ser invocado com `@general` nas mensagens.
-
-Saiba mais sobre [agents](https://opencode.ai/docs/agents).
-
-### Documentação
-
-Para mais informações sobre como configurar o OpenCode, [**veja nossa documentação**](https://opencode.ai/docs).
-
-### Contribuir
-
-Se você tem interesse em contribuir com o OpenCode, leia os [contributing docs](./CONTRIBUTING.md) antes de enviar um pull request.
-
-### Construindo com OpenCode
-
-Se você estiver trabalhando em um projeto relacionado ao OpenCode e estiver usando "opencode" como parte do nome (por exemplo, "opencode-dashboard" ou "opencode-mobile"), adicione uma nota no README para deixar claro que não foi construído pela equipe do OpenCode e não é afiliado a nós de nenhuma forma.
-
-### FAQ
-
-#### Como isso é diferente do Claude Code?
-
-É muito parecido com o Claude Code em termos de capacidade. Aqui estão as principais diferenças:
-
-- 100% open source
-- Não está acoplado a nenhum provedor. Embora recomendemos os modelos que oferecemos pelo [OpenCode Zen](https://opencode.ai/zen); o OpenCode pode ser usado com Claude, OpenAI, Google ou até modelos locais. À medida que os modelos evoluem, as diferenças diminuem e os preços caem, então ser provider-agnostic é importante.
-- Suporte a LSP pronto para uso
-- Foco em TUI. O OpenCode é construído por usuários de neovim e pelos criadores do [terminal.shop](https://terminal.shop); vamos levar ao limite o que é possível no terminal.
-- Arquitetura cliente/servidor. Isso, por exemplo, permite executar o OpenCode no seu computador enquanto você o controla remotamente por um aplicativo mobile. Isso significa que o frontend TUI é apenas um dos possíveis clientes.

-
-> [!TIP]
-> Ukloni verzije starije od 0.1.x prije instalacije.
-
-### Desktop aplikacija (BETA)
-
-OpenCode je dostupan i kao desktop aplikacija. Preuzmi je direktno sa [stranice izdanja](https://github.com/anomalyco/opencode/releases) ili sa [opencode.ai/download](https://opencode.ai/download).
-
-| Platforma             | Preuzimanje                           |
-| --------------------- | ------------------------------------- |
-| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |
-| macOS (Intel)         | `opencode-desktop-darwin-x64.dmg`     |
-| Windows               | `opencode-desktop-windows-x64.exe`    |
-| Linux                 | `.deb`, `.rpm`, ili AppImage          |

-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
-```
-
-#### Instalacijski direktorij
-
-Instalacijska skripta koristi sljedeći redoslijed prioriteta za putanju instalacije:
-
-1. `$OPENCODE_INSTALL_DIR` - Prilagođeni instalacijski direktorij
-2. `$XDG_BIN_DIR` - Putanja usklađena sa XDG Base Directory specifikacijom
-3. `$HOME/bin` - Standardni korisnički bin direktorij (ako postoji ili se može kreirati)
-4. `$HOME/.opencode/bin` - Podrazumijevana rezervna lokacija
-
-```bash
-# Primjeri
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Agenti
-
-OpenCode uključuje dva ugrađena agenta između kojih možeš prebacivati tasterom `Tab`.
-
-- **build** - Podrazumijevani agent sa punim pristupom za razvoj
-- **plan** - Agent samo za čitanje za analizu i istraživanje koda
-  - Podrazumijevano zabranjuje izmjene datoteka
-  - Traži dozvolu prije pokretanja bash komandi
-  - Idealan za istraživanje nepoznatih codebase-ova ili planiranje izmjena
-
-Uključen je i **general** pod-agent za složene pretrage i višekoračne zadatke.
-Koristi se interno i može se pozvati pomoću `@general` u porukama.
-
-Saznaj više o [agentima](https://opencode.ai/docs/agents).
-
-### Dokumentacija
-
-Za više informacija o konfiguraciji OpenCode-a, [**pogledaj dokumentaciju**](https://opencode.ai/docs).
-
-### Doprinosi
-
-Ako želiš doprinositi OpenCode-u, pročitaj [upute za doprinošenje](./CONTRIBUTING.md) prije slanja pull requesta.
-
-### Gradnja na OpenCode-u
-
-Ako radiš na projektu koji je povezan s OpenCode-om i koristi "opencode" kao dio naziva, npr. "opencode-dashboard" ili "opencode-mobile", dodaj napomenu u svoj README da projekat nije napravio OpenCode tim i da nije povezan s nama.
-
-### FAQ
-
-#### Po čemu se razlikuje od Claude Code-a?
-
-Po mogućnostima je vrlo sličan Claude Code-u. Ključne razlike su:
-
-- 100% open source
-- Nije vezan za jednog provajdera. Iako preporučujemo modele koje nudimo kroz [OpenCode Zen](https://opencode.ai/zen), OpenCode možeš koristiti s Claude, OpenAI, Google ili čak lokalnim modelima. Kako modeli napreduju, razlike među njima će se smanjivati, a cijene padati, zato je nezavisnost od provajdera važna.
-- LSP podrška odmah po instalaciji
-- Fokus na TUI. OpenCode grade neovim korisnici i kreatori [terminal.shop](https://terminal.shop); pomjeraćemo granice onoga što je moguće u terminalu.
-- Klijent/server arhitektura. To, recimo, omogućava da OpenCode radi na tvom računaru dok ga daljinski koristiš iz mobilne aplikacije, što znači da je TUI frontend samo jedan od mogućih klijenata.

-
-### Desktop-app (BETA)
-
-OpenCode findes også som desktop-app. Download direkte fra [releases-siden](https://github.com/anomalyco/opencode/releases) eller [opencode.ai/download](https://opencode.ai/download).
-
-| Platform              | Download                              |
-| --------------------- | ------------------------------------- |
-| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |

-brew install --cask opencode-desktop
-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
-```
-
-#### Installationsmappe
-
-Installationsscriptet bruger følgende prioriteringsrækkefølge for installationsstien:
-
-1. `$OPENCODE_INSTALL_DIR` - Tilpasset installationsmappe
-2. `$XDG_BIN_DIR` - Sti der følger XDG Base Directory Specification
-3. `$HOME/bin` - Standard bruger-bin-mappe (hvis den findes eller kan oprettes)
-4. `$HOME/.opencode/bin` - Standard fallback
-
-```bash
-# Eksempler
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Agents
-
-OpenCode har to indbyggede agents, som du kan skifte mellem med `Tab`-tasten.
-
-- **build** - Standard, agent med fuld adgang til udviklingsarbejde
-- **plan** - Skrivebeskyttet agent til analyse og kodeudforskning
-  - Afviser filredigering som standard
-  - Spørger om tilladelse før bash-kommandoer
-  - Ideel til at udforske ukendte kodebaser eller planlægge ændringer
-
-Derudover findes der en **general**-subagent til komplekse søgninger og flertrinsopgaver.
-Den bruges internt og kan kaldes via `@general` i beskeder.
-
-Læs mere om [agents](https://opencode.ai/docs/agents).
-
-### Dokumentation
-
-For mere info om konfiguration af OpenCode, [**se vores docs**](https://opencode.ai/docs).
-
-### Bidrag
-
-Hvis du vil bidrage til OpenCode, så læs vores [contributing docs](./CONTRIBUTING.md) før du sender en pull request.
-
-### Bygget på OpenCode
-
-Hvis du arbejder på et projekt der er relateret til OpenCode og bruger "opencode" som en del af navnet; f.eks. "opencode-dashboard" eller "opencode-mobile", så tilføj en note i din README, der tydeliggør at projektet ikke er bygget af OpenCode-teamet og ikke er tilknyttet os på nogen måde.
-
-### FAQ
-
-#### Hvordan adskiller dette sig fra Claude Code?
-
-Det minder meget om Claude Code i forhold til funktionalitet. Her er de vigtigste forskelle:
-
-- 100% open source
-- Ikke låst til en udbyder. Selvom vi anbefaler modellerne via [OpenCode Zen](https://opencode.ai/zen); kan OpenCode bruges med Claude, OpenAI, Google eller endda lokale modeller. Efterhånden som modeller udvikler sig vil forskellene mindskes og priserne falde, så det er vigtigt at være provider-agnostic.
-- LSP-support out of the box
-- Fokus på TUI. OpenCode er bygget af neovim-brugere og skaberne af [terminal.shop](https://terminal.shop); vi vil skubbe grænserne for hvad der er muligt i terminalen.
-- Klient/server-arkitektur. Det kan f.eks. lade OpenCode køre på din computer, mens du styrer den eksternt fra en mobilapp. Det betyder at TUI-frontend'en kun er en af de mulige clients.

-
-#### Installationsverzeichnis
-
-Das Installationsskript beachtet die folgende Prioritätsreihenfolge für den Installationspfad:
-
-1. `$OPENCODE_INSTALL_DIR` - Benutzerdefiniertes Installationsverzeichnis
-2. `$XDG_BIN_DIR` - XDG Base Directory Specification-konformer Pfad
-3. `$HOME/bin` - Standard-Binärverzeichnis des Users (falls vorhanden oder erstellbar)
-4. `$HOME/.opencode/bin` - Standard-Fallback
-
-```bash
-# Beispiele
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Agents
-
-OpenCode enthält zwei eingebaute Agents, zwischen denen du mit der `Tab`-Taste wechseln kannst.
-
-- **build** - Standard-Agent mit vollem Zugriff für Entwicklungsarbeit
-- **plan** - Nur-Lese-Agent für Analyse und Code-Exploration
-  - Verweigert Datei-Edits standardmäßig
-  - Fragt vor dem Ausführen von bash-Befehlen nach
-  - Ideal zum Erkunden unbekannter Codebases oder zum Planen von Änderungen
-
-Außerdem ist ein **general**-Subagent für komplexe Suchen und mehrstufige Aufgaben enthalten.
-Dieser wird intern genutzt und kann in Nachrichten mit `@general` aufgerufen werden.
-
-Mehr dazu unter [Agents](https://opencode.ai/docs/agents).
-
-### Dokumentation
-
-Mehr Infos zur Konfiguration von OpenCode findest du in unseren [**Docs**](https://opencode.ai/docs).
-
-### Beitragen
-
-Wenn du zu OpenCode beitragen möchtest, lies bitte unsere [Contributing Docs](./CONTRIBUTING.md), bevor du einen Pull Request einreichst.
-
-### Auf OpenCode aufbauen
-
-Wenn du an einem Projekt arbeitest, das mit OpenCode zusammenhängt und "opencode" als Teil seines Namens verwendet (z.B. "opencode-dashboard" oder "opencode-mobile"), füge bitte einen Hinweis in deine README ein, dass es nicht vom OpenCode-Team gebaut wird und nicht in irgendeiner Weise mit uns verbunden ist.
-
-### FAQ
-
-#### Worin unterscheidet sich das von Claude Code?
-
-In Bezug auf die Fähigkeiten ist es Claude Code sehr ähnlich. Hier sind die wichtigsten Unterschiede:
-
-- 100% open source
-- Nicht an einen Anbieter gekoppelt. Wir empfehlen die Modelle aus [OpenCode Zen](https://opencode.ai/zen); OpenCode kann aber auch mit Claude, OpenAI, Google oder sogar lokalen Modellen genutzt werden. Mit der Weiterentwicklung der Modelle werden die Unterschiede kleiner und die Preise sinken, deshalb ist Provider-Unabhängigkeit wichtig.
-- LSP-Unterstützung direkt nach dem Start
-- Fokus auf TUI. OpenCode wird von Neovim-Nutzern und den Machern von [terminal.shop](https://terminal.shop) gebaut; wir treiben die Grenzen dessen, was im Terminal möglich ist.
-- Client/Server-Architektur. Das ermöglicht z.B., OpenCode auf deinem Computer laufen zu lassen, während du es von einer mobilen App aus fernsteuerst. Das TUI-Frontend ist nur einer der möglichen Clients.

-#### Directorio de instalación
-
-El script de instalación respeta el siguiente orden de prioridad para la ruta de instalación:
-
-1. `$OPENCODE_INSTALL_DIR` - Directorio de instalación personalizado
-2. `$XDG_BIN_DIR` - Ruta compatible con la especificación XDG Base Directory
-3. `$HOME/bin` - Directorio binario estándar del usuario (si existe o se puede crear)
-4. `$HOME/.opencode/bin` - Alternativa por defecto
-
-```bash
-# Ejemplos
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Agents
-
-OpenCode incluye dos agents integrados que puedes alternar con la tecla `Tab`.
-
-- **build** - Por defecto, agent con acceso completo para trabajo de desarrollo
-- **plan** - Agent de solo lectura para análisis y exploración de código
-  - Niega ediciones de archivos por defecto
-  - Pide permiso antes de ejecutar comandos bash
-  - Ideal para explorar codebases desconocidas o planificar cambios
-
-Además, incluye un subagent **general** para búsquedas complejas y tareas de varios pasos.
-Se usa internamente y se puede invocar con `@general` en los mensajes.
-
-Más información sobre [agents](https://opencode.ai/docs/agents).
-

-
-### Construyendo sobre OpenCode
-
-Si estás trabajando en un proyecto relacionado con OpenCode y usas "opencode" como parte del nombre; por ejemplo, "opencode-dashboard" u "opencode-mobile", agrega una nota en tu README para aclarar que no está construido por el equipo de OpenCode y que no está afiliado con nosotros de ninguna manera.
-
-### FAQ
-
-#### ¿En qué se diferencia de Claude Code?
-
-Es muy similar a Claude Code en cuanto a capacidades. Estas son las diferencias clave:
-
-- 100% open source
-- No está acoplado a ningún proveedor. Aunque recomendamos los modelos que ofrecemos a través de [OpenCode Zen](https://opencode.ai/zen); OpenCode se puede usar con Claude, OpenAI, Google o incluso modelos locales. A medida que evolucionan los modelos, las brechas se cerrarán y los precios bajarán, por lo que ser agnóstico al proveedor es importante.
-- Soporte LSP listo para usar
-- Un enfoque en la TUI. OpenCode está construido por usuarios de neovim y los creadores de [terminal.shop](https://terminal.shop); vamos a empujar los límites de lo que es posible en la terminal.
-- Arquitectura cliente/servidor. Esto, por ejemplo, permite ejecutar OpenCode en tu computadora mientras lo controlas de forma remota desde una app móvil. Esto significa que el frontend TUI es solo uno de los posibles clientes.

-```
-
-> [!TIP]
-> Αφαίρεσε παλαιότερες εκδόσεις από τη 0.1.x πριν από την εγκατάσταση.
-
-### Εφαρμογή Desktop (BETA)
-
-Το OpenCode είναι επίσης διαθέσιμο ως εφαρμογή. Κατέβασε το απευθείας από τη [σελίδα εκδόσεων](https://github.com/anomalyco/opencode/releases) ή το [opencode.ai/download](https://opencode.ai/download).
-
-| Πλατφόρμα             | Λήψη                                  |
-| --------------------- | ------------------------------------- |
-| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |
-| macOS (Intel)         | `opencode-desktop-darwin-x64.dmg`     |

-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
-```
-
-#### Κατάλογος Εγκατάστασης
-
-Το script εγκατάστασης τηρεί την ακόλουθη σειρά προτεραιότητας για τη διαδρομή εγκατάστασης:
-
-1. `$OPENCODE_INSTALL_DIR` - Προσαρμοσμένος κατάλογος εγκατάστασης
-2. `$XDG_BIN_DIR` - Διαδρομή συμβατή με τις προδιαγραφές XDG Base Directory
-3. `$HOME/bin` - Τυπικός κατάλογος εκτελέσιμων αρχείων χρήστη (εάν υπάρχει ή μπορεί να δημιουργηθεί)
-4. `$HOME/.opencode/bin` - Προεπιλεγμένη εφεδρική διαδρομή
-
-```bash
-# Παραδείγματα
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Πράκτορες
-
-Το OpenCode περιλαμβάνει δύο ενσωματωμένους πράκτορες μεταξύ των οποίων μπορείτε να εναλλάσσεστε με το πλήκτρο `Tab`.
-
-- **build** - Προεπιλεγμένος πράκτορας με πλήρη πρόσβαση για εργασία πάνω σε κώδικα
-- **plan** - Πράκτορας μόνο ανάγνωσης για ανάλυση και εξερεύνηση κώδικα
-  - Αρνείται την επεξεργασία αρχείων από προεπιλογή
-  - Ζητά άδεια πριν εκτελέσει εντολές bash
-  - Ιδανικός για εξερεύνηση άγνωστων αρχείων πηγαίου κώδικα ή σχεδιασμό αλλαγών
-
-Περιλαμβάνεται επίσης ένας **general** υποπράκτορας για σύνθετες αναζητήσεις και πολυβηματικές διεργασίες.
-Χρησιμοποιείται εσωτερικά και μπορεί να κληθεί χρησιμοποιώντας `@general` στα μηνύματα.
-
-Μάθετε περισσότερα για τους [πράκτορες](https://opencode.ai/docs/agents).
-
-### Οδηγός Χρήσης
-
-Για περισσότερες πληροφορίες σχετικά με τη ρύθμιση του OpenCode, [**πλοηγήσου στον οδηγό χρήσης μας**](https://opencode.ai/docs).
-
-### Συνεισφορά
-
-Εάν ενδιαφέρεσαι να συνεισφέρεις στο OpenCode, διαβάστε τα [οδηγό χρήσης συνεισφοράς](./CONTRIBUTING.md) πριν υποβάλεις ένα pull request.
-
-### Δημιουργία πάνω στο OpenCode
-
-Εάν εργάζεσαι σε ένα έργο σχετικό με το OpenCode και χρησιμοποιείτε το "opencode" ως μέρος του ονόματός του, για παράδειγμα "opencode-dashboard" ή "opencode-mobile", πρόσθεσε μια σημείωση στο README σας για να διευκρινίσεις ότι δεν είναι κατασκευασμένο από την ομάδα του OpenCode και δεν έχει καμία σχέση με εμάς.
-
-### Συχνές Ερωτήσεις
-
-#### Πώς διαφέρει αυτό από το Claude Code;
-
-Είναι πολύ παρόμοιο με το Claude Code ως προς τις δυνατότητες. Ακολουθούν οι βασικές διαφορές:
-
-- 100% ανοιχτού κώδικα
-- Δεν είναι συνδεδεμένο με κανέναν πάροχο. Αν και συνιστούμε τα μοντέλα που παρέχουμε μέσω του [OpenCode Zen](https://opencode.ai/zen), το OpenCode μπορεί να χρησιμοποιηθεί με Claude, OpenAI, Google, ή ακόμα και τοπικά μοντέλα. Καθώς τα μοντέλα εξελίσσονται, τα κενά μεταξύ τους θα κλείσουν και οι τιμές θα μειωθούν, οπότε είναι σημαντικό να είσαι ανεξάρτητος από τον πάροχο.
-- Out-of-the-box υποστήριξη LSP
-- Εστίαση στο TUI. Το OpenCode είναι κατασκευασμένο από χρήστες που χρησιμοποιούν neovim και τους δημιουργούς του [terminal.shop](https://terminal.shop)· θα εξαντλήσουμε τα όρια του τι είναι δυνατό στο terminal.
-- Αρχιτεκτονική client/server. Αυτό, για παράδειγμα, μπορεί να επιτρέψει στο OpenCode να τρέχει στον υπολογιστή σου ενώ το χειρίζεσαι εξ αποστάσεως από μια εφαρμογή κινητού, που σημαίνει ότι το TUI frontend είναι μόνο ένας από τους πιθανούς clients.

-### Agenti
-
-OpenCode include due agenti integrati tra cui puoi passare usando il tasto `Tab`.
-
-- **build** – Predefinito, agente con accesso completo per il lavoro di sviluppo
-- **plan** – Agente in sola lettura per analisi ed esplorazione del codice
-  - Nega le modifiche ai file per impostazione predefinita
-  - Chiede il permesso prima di eseguire comandi bash
-  - Ideale per esplorare codebase sconosciute o pianificare modifiche
-
-È inoltre incluso un sotto-agente **general** per ricerche complesse e attività multi-step.
-Viene utilizzato internamente e può essere invocato usando `@general` nei messaggi.
-
-Scopri di più sugli [agenti](https://opencode.ai/docs/agents).
-
-### Documentazione
-
-Per maggiori informazioni su come configurare OpenCode, [**consulta la nostra documentazione**](https://opencode.ai/docs).
-
-### Contribuire
-
-Se sei interessato a contribuire a OpenCode, leggi la nostra [guida alla contribuzione](./CONTRIBUTING.md) prima di inviare una pull request.
-
-### Costruire su OpenCode
-
-Se stai lavorando a un progetto correlato a OpenCode e che utilizza “opencode” come parte del nome (ad esempio “opencode-dashboard” o “opencode-mobile”), aggiungi una nota nel tuo README per chiarire che non è sviluppato dal team OpenCode e che non è affiliato in alcun modo con noi.
-
-### FAQ
-
-#### In cosa è diverso da Claude Code?
-
-È molto simile a Claude Code in termini di funzionalità. Ecco le principali differenze:
-
-- 100% open source
-- Non è legato a nessun provider. Anche se consigliamo i modelli forniti tramite [OpenCode Zen](https://opencode.ai/zen), OpenCode può essere utilizzato con Claude, OpenAI, Google o persino modelli locali. Con l’evoluzione dei modelli, le differenze tra di essi si ridurranno e i prezzi scenderanno, quindi essere indipendenti dal provider è importante.
-- Supporto LSP pronto all’uso
-- Forte attenzione alla TUI. OpenCode è sviluppato da utenti neovim e dai creatori di [terminal.shop](https://terminal.shop); spingeremo al limite ciò che è possibile fare nel terminale.
-- Architettura client/server. Questo, ad esempio, permette a OpenCode di girare sul tuo computer mentre lo controlli da remoto tramite un’app mobile. La frontend TUI è quindi solo uno dei possibili client.

-
-### コントリビュート
-
-OpenCode に貢献したい場合は、Pull Request を送る前に [contributing docs](./CONTRIBUTING.md) を読んでください。
-
-### OpenCode の上に構築する
-
-OpenCode に関連するプロジェクトで、名前に "opencode"（例: "opencode-dashboard" や "opencode-mobile"）を含める場合は、そのプロジェクトが OpenCode チームによって作られたものではなく、いかなる形でも関係がないことを README に明記してください。
-
-### FAQ
-
-#### Claude Code との違いは？
-
-機能面では Claude Code と非常に似ています。主な違いは次のとおりです。
-
-- 100% オープンソース
-- 特定のプロバイダーに依存しません。[OpenCode Zen](https://opencode.ai/zen) で提供しているモデルを推奨しますが、OpenCode は Claude、OpenAI、Google、またはローカルモデルでも利用できます。モデルが進化すると差は縮まり価格も下がるため、provider-agnostic であることが重要です。
-- そのまま使える LSP サポート
-- TUI にフォーカス。OpenCode は neovim ユーザーと [terminal.shop](https://terminal.shop) の制作者によって作られており、ターミナルで可能なことの限界を押し広げます。
-- クライアント/サーバー構成。例えば OpenCode をあなたのPCで動かし、モバイルアプリからリモート操作できます。TUI フロントエンドは複数あるクライアントの1つにすぎません。

-### Agents
-
-OpenCode 에는 내장 에이전트 2개가 있으며 `Tab` 키로 전환할 수 있습니다.
-
-- **build** - 기본값, 개발 작업을 위한 전체 권한 에이전트
-- **plan** - 분석 및 코드 탐색을 위한 읽기 전용 에이전트
-  - 기본적으로 파일 편집을 거부
-  - bash 명령 실행 전에 권한을 요청
-  - 낯선 코드베이스를 탐색하거나 변경을 계획할 때 적합
-
-또한 복잡한 검색과 여러 단계 작업을 위한 **general** 서브 에이전트가 포함되어 있습니다.
-내부적으로 사용되며, 메시지에서 `@general` 로 호출할 수 있습니다.
-
-[agents](https://opencode.ai/docs/agents) 에 대해 더 알아보세요.
-
-### 문서
-
-OpenCode 설정에 대한 자세한 내용은 [**문서**](https://opencode.ai/docs) 를 참고하세요.
-
-### 기여하기
-
-OpenCode 에 기여하고 싶다면, Pull Request 를 제출하기 전에 [contributing docs](./CONTRIBUTING.md) 를 읽어주세요.
-
-### OpenCode 기반으로 만들기
-
-OpenCode 와 관련된 프로젝트를 진행하면서 이름에 "opencode"(예: "opencode-dashboard" 또는 "opencode-mobile") 를 포함한다면, README 에 해당 프로젝트가 OpenCode 팀이 만든 것이 아니며 어떤 방식으로도 우리와 제휴되어 있지 않다는 점을 명시해 주세요.
-
-### FAQ
-
-#### Claude Code 와는 무엇이 다른가요?
-
-기능 면에서는 Claude Code 와 매우 유사합니다. 주요 차이점은 다음과 같습니다.
-
-- 100% 오픈 소스
-- 특정 제공자에 묶여 있지 않습니다. [OpenCode Zen](https://opencode.ai/zen) 을 통해 제공하는 모델을 권장하지만, OpenCode 는 Claude, OpenAI, Google 또는 로컬 모델과도 사용할 수 있습니다. 모델이 발전하면서 격차는 줄고 가격은 내려가므로 provider-agnostic 인 것이 중요합니다.
-- 기본으로 제공되는 LSP 지원
-- TUI 에 집중. OpenCode 는 neovim 사용자와 [terminal.shop](https://terminal.shop) 제작자가 만들었으며, 터미널에서 가능한 것의 한계를 밀어붙입니다.
-- 클라이언트/서버 아키텍처. 예를 들어 OpenCode 를 내 컴퓨터에서 실행하면서 모바일 앱으로 원격 조작할 수 있습니다. 즉, TUI 프런트엔드는 가능한 여러 클라이언트 중 하나일 뿐입니다.

-```
-
-> [!TIP]
-> Fjern versjoner eldre enn 0.1.x før du installerer.
-
-### Desktop-app (BETA)
-
-OpenCode er også tilgjengelig som en desktop-app. Last ned direkte fra [releases-siden](https://github.com/anomalyco/opencode/releases) eller [opencode.ai/download](https://opencode.ai/download).
-
-| Plattform             | Nedlasting                            |
-| --------------------- | ------------------------------------- |
-| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |
-| macOS (Intel)         | `opencode-desktop-darwin-x64.dmg`     |
-| Windows               | `opencode-desktop-windows-x64.exe`    |
-| Linux                 | `.deb`, `.rpm` eller AppImage         |
-
-```bash
-# macOS (Homebrew)
-brew install --cask opencode-desktop
-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
-```
-
-#### Installasjonsmappe
-
-Installasjonsskriptet bruker følgende prioritet for installasjonsstien:
-
-1. `$OPENCODE_INSTALL_DIR` - Egendefinert installasjonsmappe
-2. `$XDG_BIN_DIR` - Sti som følger XDG Base Directory Specification
-3. `$HOME/bin` - Standard brukerbinar-mappe (hvis den finnes eller kan opprettes)
-4. `$HOME/.opencode/bin` - Standard fallback
-
-```bash
-# Eksempler
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Agents
-
-OpenCode har to innebygde agents du kan bytte mellom med `Tab`-tasten.
-
-- **build** - Standard, agent med full tilgang for utviklingsarbeid
-- **plan** - Skrivebeskyttet agent for analyse og kodeutforsking
-  - Nekter filendringer som standard
-  - Spør om tillatelse før bash-kommandoer
-  - Ideell for å utforske ukjente kodebaser eller planlegge endringer
-
-Det finnes også en **general**-subagent for komplekse søk og flertrinnsoppgaver.
-Den brukes internt og kan kalles via `@general` i meldinger.
-
-Les mer om [agents](https://opencode.ai/docs/agents).
-
-### Dokumentasjon
-
-For mer info om hvordan du konfigurerer OpenCode, [**se dokumentasjonen**](https://opencode.ai/docs).
-
-### Bidra
-
-Hvis du vil bidra til OpenCode, les [contributing docs](./CONTRIBUTING.md) før du sender en pull request.
-
-### Bygge på OpenCode
-
-Hvis du jobber med et prosjekt som er relatert til OpenCode og bruker "opencode" som en del av navnet; for eksempel "opencode-dashboard" eller "opencode-mobile", legg inn en merknad i README som presiserer at det ikke er bygget av OpenCode-teamet og ikke er tilknyttet oss på noen måte.
-
-### FAQ
-
-#### Hvordan er dette forskjellig fra Claude Code?
-
-Det er veldig likt Claude Code når det gjelder funksjonalitet. Her er de viktigste forskjellene:
-
-- 100% open source
-- Ikke knyttet til en bestemt leverandør. Selv om vi anbefaler modellene vi tilbyr gjennom [OpenCode Zen](https://opencode.ai/zen); kan OpenCode brukes med Claude, OpenAI, Google eller til og med lokale modeller. Etter hvert som modellene utvikler seg vil gapene lukkes og prisene gå ned, så det er viktig å være provider-agnostic.
-- LSP-støtte rett ut av boksen
-- Fokus på TUI. OpenCode er bygget av neovim-brukere og skaperne av [terminal.shop](https://terminal.shop); vi kommer til å presse grensene for hva som er mulig i terminalen.
-- Klient/server-arkitektur. Dette kan for eksempel la OpenCode kjøre på maskinen din, mens du styrer den eksternt fra en mobilapp. Det betyr at TUI-frontend'en bare er en av de mulige klientene.

-
-> [!TIP]
-> Przed instalacją usuń wersje starsze niż 0.1.x.
-
-### Aplikacja desktopowa (BETA)
-
-OpenCode jest także dostępny jako aplikacja desktopowa. Pobierz ją bezpośrednio ze strony [releases](https://github.com/anomalyco/opencode/releases) lub z [opencode.ai/download](https://opencode.ai/download).
-
-| Platforma             | Pobieranie                            |
-| --------------------- | ------------------------------------- |
-| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |

-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
-```
-
-#### Katalog instalacji
-
-Skrypt instalacyjny stosuje następujący priorytet wyboru ścieżki instalacji:
-
-1. `$OPENCODE_INSTALL_DIR` - Własny katalog instalacji
-2. `$XDG_BIN_DIR` - Ścieżka zgodna ze specyfikacją XDG Base Directory
-3. `$HOME/bin` - Standardowy katalog binarny użytkownika (jeśli istnieje lub można go utworzyć)
-4. `$HOME/.opencode/bin` - Domyślny fallback
-
-```bash
-# Przykłady
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Agents
-
-OpenCode zawiera dwóch wbudowanych agentów, między którymi możesz przełączać się klawiszem `Tab`.
-
-- **build** - Domyślny agent z pełnym dostępem do pracy developerskiej
-- **plan** - Agent tylko do odczytu do analizy i eksploracji kodu
-  - Domyślnie odmawia edycji plików
-  - Pyta o zgodę przed uruchomieniem komend bash
-  - Idealny do poznawania nieznanych baz kodu lub planowania zmian
-
-Dodatkowo jest subagent **general** do złożonych wyszukiwań i wieloetapowych zadań.
-Jest używany wewnętrznie i można go wywołać w wiadomościach przez `@general`.
-
-Dowiedz się więcej o [agents](https://opencode.ai/docs/agents).
-
-### Dokumentacja
-
-Więcej informacji o konfiguracji OpenCode znajdziesz w [**dokumentacji**](https://opencode.ai/docs).
-
-### Współtworzenie
-
-Jeśli chcesz współtworzyć OpenCode, przeczytaj [contributing docs](./CONTRIBUTING.md) przed wysłaniem pull requesta.
-
-### Budowanie na OpenCode
-
-Jeśli pracujesz nad projektem związanym z OpenCode i używasz "opencode" jako części nazwy (na przykład "opencode-dashboard" lub "opencode-mobile"), dodaj proszę notatkę do swojego README, aby wyjaśnić, że projekt nie jest tworzony przez zespół OpenCode i nie jest z nami w żaden sposób powiązany.
-
-### FAQ
-
-#### Czym to się różni od Claude Code?
-
-Jest bardzo podobne do Claude Code pod względem możliwości. Oto kluczowe różnice:
-
-- 100% open source
-- Niezależne od dostawcy. Chociaż polecamy modele oferowane przez [OpenCode Zen](https://opencode.ai/zen); OpenCode może być używany z Claude, OpenAI, Google, a nawet z modelami lokalnymi. W miarę jak modele ewoluują, różnice będą się zmniejszać, a ceny spadać, więc ważna jest niezależność od dostawcy.
-- Wbudowane wsparcie LSP
-- Skupienie na TUI. OpenCode jest budowany przez użytkowników neovim i twórców [terminal.shop](https://terminal.shop); przesuwamy granice tego, co jest możliwe w terminalu.
-- Architektura klient/serwer. Pozwala np. uruchomić OpenCode na twoim komputerze, a sterować nim zdalnie z aplikacji mobilnej. To znaczy, że frontend TUI jest tylko jednym z możliwych klientów.

-
-### Десктопное приложение (BETA)
-
-OpenCode также доступен как десктопное приложение. Скачайте его со [страницы релизов](https://github.com/anomalyco/opencode/releases) или с [opencode.ai/download](https://opencode.ai/download).
-
-| Платформа             | Загрузка                              |
-| --------------------- | ------------------------------------- |
-| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |
-| macOS (Intel)         | `opencode-desktop-darwin-x64.dmg`     |
-| Windows               | `opencode-desktop-windows-x64.exe`    |

-brew install --cask opencode-desktop
-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
-```
-
-#### Каталог установки
-
-Скрипт установки выбирает путь установки в следующем порядке приоритета:
-
-1. `$OPENCODE_INSTALL_DIR` - Пользовательский каталог установки
-2. `$XDG_BIN_DIR` - Путь, совместимый со спецификацией XDG Base Directory
-3. `$HOME/bin` - Стандартный каталог пользовательских бинарников (если существует или можно создать)
-4. `$HOME/.opencode/bin` - Fallback по умолчанию
-
-```bash
-# Примеры
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Agents
-
-В OpenCode есть два встроенных агента, между которыми можно переключаться клавишей `Tab`.
-
-- **build** - По умолчанию, агент с полным доступом для разработки
-- **plan** - Агент только для чтения для анализа и изучения кода
-  - По умолчанию запрещает редактирование файлов
-  - Запрашивает разрешение перед выполнением bash-команд
-  - Идеален для изучения незнакомых кодовых баз или планирования изменений
-
-Также включен сабагент **general** для сложных поисков и многошаговых задач.
-Он используется внутренне и может быть вызван в сообщениях через `@general`.
-
-Подробнее об [agents](https://opencode.ai/docs/agents).
-
-### Документация
-
-Больше информации о том, как настроить OpenCode: [**наши docs**](https://opencode.ai/docs).
-
-### Вклад
-
-Если вы хотите внести вклад в OpenCode, прочитайте [contributing docs](./CONTRIBUTING.md) перед тем, как отправлять pull request.
-
-### Разработка на базе OpenCode
-
-Если вы делаете проект, связанный с OpenCode, и используете "opencode" как часть имени (например, "opencode-dashboard" или "opencode-mobile"), добавьте примечание в README, чтобы уточнить, что проект не создан командой OpenCode и не аффилирован с нами.
-
-### FAQ
-
-#### Чем это отличается от Claude Code?
-
-По возможностям это очень похоже на Claude Code. Вот ключевые отличия:
-
-- 100% open source
-- Не привязано к одному провайдеру. Мы рекомендуем модели из [OpenCode Zen](https://opencode.ai/zen); но OpenCode можно использовать с Claude, OpenAI, Google или даже локальными моделями. По мере развития моделей разрыв будет сокращаться, а цены падать, поэтому важна независимость от провайдера.
-- Поддержка LSP из коробки
-- Фокус на TUI. OpenCode построен пользователями neovim и создателями [terminal.shop](https://terminal.shop); мы будем раздвигать границы того, что возможно в терминале.
-- Архитектура клиент/сервер. Например, это позволяет запускать OpenCode на вашем компьютере, а управлять им удаленно из мобильного приложения. Это значит, что TUI-фронтенд - лишь один из возможных клиентов.

-```
-
-> [!TIP]
-> ลบเวอร์ชันที่เก่ากว่า 0.1.x ก่อนติดตั้ง
-
-### แอปพลิเคชันเดสก์ท็อป (เบต้า)
-
-OpenCode มีให้ใช้งานเป็นแอปพลิเคชันเดสก์ท็อป ดาวน์โหลดโดยตรงจาก [หน้ารุ่น](https://github.com/anomalyco/opencode/releases) หรือ [opencode.ai/download](https://opencode.ai/download)
-
-| แพลตฟอร์ม             | ดาวน์โหลด                             |
-| --------------------- | ------------------------------------- |
-| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |
-| macOS (Intel)         | `opencode-desktop-darwin-x64.dmg`     |
-| Windows               | `opencode-desktop-windows-x64.exe`    |
-| Linux                 | `.deb`, `.rpm`, หรือ AppImage         |
-
-```bash
-# macOS (Homebrew)
-brew install --cask opencode-desktop
-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
-```
-
-#### ไดเรกทอรีการติดตั้ง
-
-สคริปต์การติดตั้งจะใช้ลำดับความสำคัญตามเส้นทางการติดตั้ง:
-
-1. `$OPENCODE_INSTALL_DIR` - ไดเรกทอรีการติดตั้งที่กำหนดเอง
-2. `$XDG_BIN_DIR` - เส้นทางที่สอดคล้องกับ XDG Base Directory Specification
-3. `$HOME/bin` - ไดเรกทอรีไบนารีผู้ใช้มาตรฐาน (หากมีอยู่หรือสามารถสร้างได้)
-4. `$HOME/.opencode/bin` - ค่าสำรองเริ่มต้น
-
-```bash
-# ตัวอย่าง
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### เอเจนต์
-
-OpenCode รวมเอเจนต์ในตัวสองตัวที่คุณสามารถสลับได้ด้วยปุ่ม `Tab`
-
-- **build** - เอเจนต์เริ่มต้น มีสิทธิ์เข้าถึงแบบเต็มสำหรับงานพัฒนา
-- **plan** - เอเจนต์อ่านอย่างเดียวสำหรับการวิเคราะห์และการสำรวจโค้ด
-  - ปฏิเสธการแก้ไขไฟล์โดยค่าเริ่มต้น
-  - ขอสิทธิ์ก่อนเรียกใช้คำสั่ง bash
-  - เหมาะสำหรับสำรวจโค้ดเบสที่ไม่คุ้นเคยหรือวางแผนการเปลี่ยนแปลง
-
-นอกจากนี้ยังมีเอเจนต์ย่อย **general** สำหรับการค้นหาที่ซับซ้อนและงานหลายขั้นตอน
-ใช้ภายในและสามารถเรียกใช้ได้โดยใช้ `@general` ในข้อความ
-
-เรียนรู้เพิ่มเติมเกี่ยวกับ [เอเจนต์](https://opencode.ai/docs/agents)
-
-### เอกสารประกอบ
-
-สำหรับข้อมูลเพิ่มเติมเกี่ยวกับวิธีกำหนดค่า OpenCode [**ไปที่เอกสารของเรา**](https://opencode.ai/docs)
-
-### การมีส่วนร่วม
-
-หากคุณสนใจที่จะมีส่วนร่วมใน OpenCode โปรดอ่าน [เอกสารการมีส่วนร่วม](./CONTRIBUTING.md) ก่อนส่ง Pull Request
-
-### การสร้างบน OpenCode
-
-หากคุณทำงานในโปรเจกต์ที่เกี่ยวข้องกับ OpenCode และใช้ "opencode" เป็นส่วนหนึ่งของชื่อ เช่น "opencode-dashboard" หรือ "opencode-mobile" โปรดเพิ่มหมายเหตุใน README ของคุณเพื่อชี้แจงว่าไม่ได้สร้างโดยทีม OpenCode และไม่ได้เกี่ยวข้องกับเราในทางใด
-
-### คำถามที่พบบ่อย
-
-#### ต่างจาก Claude Code อย่างไร?
-
-คล้ายกับ Claude Code มากในแง่ความสามารถ นี่คือความแตกต่างหลัก:
-
-- โอเพนซอร์ส 100%
-- ไม่ผูกมัดกับผู้ให้บริการใดๆ แม้ว่าเราจะแนะนำโมเดลที่เราจัดหาให้ผ่าน [OpenCode Zen](https://opencode.ai/zen) OpenCode สามารถใช้กับ Claude, OpenAI, Google หรือแม้กระทั่งโมเดลในเครื่องได้ เมื่อโมเดลพัฒนาช่องว่างระหว่างพวกมันจะปิดลงและราคาจะลดลง ดังนั้นการไม่ผูกมัดกับผู้ให้บริการจึงสำคัญ
-- รองรับ LSP ใช้งานได้ทันทีหลังการติดตั้งโดยไม่ต้องปรับแต่งหรือเปลี่ยนแปลงฟังก์ชันการทำงานใด ๆ
-- เน้นที่ TUI OpenCode สร้างโดยผู้ใช้ neovim และผู้สร้าง [terminal.shop](https://terminal.shop) เราจะผลักดันขีดจำกัดของสิ่งที่เป็นไปได้ในเทอร์มินัล
-- สถาปัตยกรรมไคลเอนต์/เซิร์ฟเวอร์ ตัวอย่างเช่น อาจอนุญาตให้ OpenCode ทำงานบนคอมพิวเตอร์ของคุณ ในขณะที่คุณสามารถขับเคลื่อนจากระยะไกลผ่านแอปมือถือ หมายความว่า TUI frontend เป็นหนึ่งในไคลเอนต์ที่เป็นไปได้เท่านั้น

-```
-
-> [!TIP]
-> Kurulumdan önce 0.1.x'ten eski sürümleri kaldırın.
-
-### Masaüstü Uygulaması (BETA)
-
-OpenCode ayrıca masaüstü uygulaması olarak da mevcuttur. Doğrudan [sürüm sayfasından](https://github.com/anomalyco/opencode/releases) veya [opencode.ai/download](https://opencode.ai/download) adresinden indirebilirsiniz.
-
-| Platform              | İndirme                               |
-| --------------------- | ------------------------------------- |

-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
-```
-
-#### Kurulum Dizini (Installation Directory)
-
-Kurulum betiği (install script), kurulum yolu (installation path) için aşağıdaki öncelik sırasını takip eder:
-
-1. `$OPENCODE_INSTALL_DIR` - Özel kurulum dizini
-2. `$XDG_BIN_DIR` - XDG Base Directory Specification uyumlu yol
-3. `$HOME/bin` - Standart kullanıcı binary dizini (varsa veya oluşturulabiliyorsa)
-4. `$HOME/.opencode/bin` - Varsayılan yedek konum
-
-```bash
-# Örnekler
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Ajanlar
-
-OpenCode, `Tab` tuşuyla aralarında geçiş yapabileceğiniz iki yerleşik (built-in) ajan içerir.
-
-- **build** - Varsayılan, geliştirme çalışmaları için tam erişimli ajan
-- **plan** - Analiz ve kod keşfi için salt okunur ajan
-  - Varsayılan olarak dosya düzenlemelerini reddeder
-  - Bash komutlarını çalıştırmadan önce izin ister
-  - Tanımadığınız kod tabanlarını keşfetmek veya değişiklikleri planlamak için ideal
-
-Ayrıca, karmaşık aramalar ve çok adımlı görevler için bir **genel** alt ajan bulunmaktadır.
-Bu dahili olarak kullanılır ve mesajlarda `@general` ile çağrılabilir.
-
-[Ajanlar](https://opencode.ai/docs/agents) hakkında daha fazla bilgi edinin.
-
-### Dokümantasyon
-
-OpenCode'u nasıl yapılandıracağınız hakkında daha fazla bilgi için [**dokümantasyonumuza göz atın**](https://opencode.ai/docs).
-
-### Katkıda Bulunma
-
-OpenCode'a katkıda bulunmak istiyorsanız, lütfen bir pull request göndermeden önce [katkıda bulunma dokümanlarımızı](./CONTRIBUTING.md) okuyun.
-
-### OpenCode Üzerine Geliştirme
-
-OpenCode ile ilgili bir proje üzerinde çalışıyorsanız ve projenizin adının bir parçası olarak "opencode" kullanıyorsanız (örneğin, "opencode-dashboard" veya "opencode-mobile"), lütfen README dosyanıza projenin OpenCode ekibi tarafından geliştirilmediğini ve bizimle hiçbir şekilde bağlantılı olmadığını belirten bir not ekleyin.
-
-### SSS
-
-#### Bu Claude Code'dan nasıl farklı?
-
-Yetenekler açısından Claude Code'a çok benzer. İşte temel farklar:
-
-- %100 açık kaynak
-- Herhangi bir sağlayıcıya bağlı değil. [OpenCode Zen](https://opencode.ai/zen) üzerinden sunduğumuz modelleri önermekle birlikte; OpenCode, Claude, OpenAI, Google veya hatta yerel modellerle kullanılabilir. Modeller geliştikçe aralarındaki farklar kapanacak ve fiyatlar düşecek, bu nedenle sağlayıcıdan bağımsız olmak önemlidir.
-- Kurulum gerektirmeyen hazır LSP desteği
-- TUI odaklı yaklaşım. OpenCode, neovim kullanıcıları ve [terminal.shop](https://terminal.shop)'un geliştiricileri tarafından geliştirilmektedir; terminalde olabileceklerin sınırlarını zorlayacağız.
-- İstemci/sunucu (client/server) mimarisi. Bu, örneğin OpenCode'un bilgisayarınızda çalışması ve siz onu bir mobil uygulamadan uzaktan yönetmenizi sağlar. TUI arayüzü olası istemcilerden sadece biridir.

-```
-
-> [!TIP]
-> Перед встановленням видаліть версії старші за 0.1.x.
-
-### Десктопний застосунок (BETA)
-
-OpenCode також доступний як десктопний застосунок. Завантажуйте напряму зі [сторінки релізів](https://github.com/anomalyco/opencode/releases) або [opencode.ai/download](https://opencode.ai/download).
-
-| Платформа             | Завантаження                          |
-| --------------------- | ------------------------------------- |
-| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |
-| macOS (Intel)         | `opencode-desktop-darwin-x64.dmg`     |
-| Windows               | `opencode-desktop-windows-x64.exe`    |
-| Linux                 | `.deb`, `.rpm` або AppImage           |
-
-```bash
-# macOS (Homebrew)
-brew install --cask opencode-desktop
-# Windows (Scoop)
-scoop bucket add extras; scoop install extras/opencode-desktop
-```
-
-#### Каталог встановлення
-
-Скрипт встановлення дотримується такого порядку пріоритету для шляху встановлення:
-
-1. `$OPENCODE_INSTALL_DIR` - Користувацький каталог встановлення
-2. `$XDG_BIN_DIR` - Шлях, сумісний зі специфікацією XDG Base Directory
-3. `$HOME/bin` - Стандартний каталог користувацьких бінарників (якщо існує або його можна створити)
-4. `$HOME/.opencode/bin` - Резервний варіант за замовчуванням
-
-```bash
-# Приклади
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Агенти
-
-OpenCode містить два вбудовані агенти, між якими можна перемикатися клавішею `Tab`.
-
-- **build** - Агент за замовчуванням із повним доступом для завдань розробки
-- **plan** - Агент лише для читання для аналізу та дослідження коду
-  - За замовчуванням забороняє редагування файлів
-  - Запитує дозвіл перед запуском bash-команд
-  - Ідеально підходить для дослідження незнайомих кодових баз або планування змін
-
-Також доступний допоміжний агент **general** для складного пошуку та багатокрокових завдань.
-Він використовується всередині системи й може бути викликаний у повідомленнях через `@general`.
-
-Дізнайтеся більше про [agents](https://opencode.ai/docs/agents).
-
-### Документація
-
-Щоб дізнатися більше про налаштування OpenCode, [**перейдіть до нашої документації**](https://opencode.ai/docs).
-
-### Внесок
-
-Якщо ви хочете зробити внесок в OpenCode, будь ласка, прочитайте нашу [документацію для контриб'юторів](./CONTRIBUTING.md) перед надсиланням pull request.
-
-### Проєкти на базі OpenCode
-
-Якщо ви працюєте над проєктом, пов'язаним з OpenCode, і використовуєте "opencode" у назві, наприклад "opencode-dashboard" або "opencode-mobile", додайте примітку до свого README.
-Уточніть, що цей проєкт не створений командою OpenCode і жодним чином не афілійований із нами.
-
-### FAQ
-
-#### Чим це відрізняється від Claude Code?
-
-За можливостями це дуже схоже на Claude Code. Ось ключові відмінності:
-
-- 100% open source
-- Немає прив'язки до конкретного провайдера. Ми рекомендуємо моделі, які надаємо через [OpenCode Zen](https://opencode.ai/zen), але OpenCode також працює з Claude, OpenAI, Google і навіть локальними моделями. З розвитком моделей різниця між ними зменшуватиметься, а ціни падатимуть, тому незалежність від провайдера має значення.
-- Підтримка LSP з коробки
-- Фокус на TUI. OpenCode створено користувачами neovim та авторами [terminal.shop](https://terminal.shop); ми й надалі розширюватимемо межі можливого в терміналі.
-- Клієнт-серверна архітектура. Наприклад, це дає змогу запускати OpenCode на вашому комп'ютері й керувати ним віддалено з мобільного застосунку, тобто TUI-фронтенд - лише один із можливих клієнтів.

-
-Tập lệnh cài đặt tuân theo thứ tự ưu tiên sau cho đường dẫn cài đặt:
-
-1. `$OPENCODE_INSTALL_DIR` - Thư mục cài đặt tùy chỉnh
-2. `$XDG_BIN_DIR` - Đường dẫn tuân thủ XDG Base Directory Specification
-3. `$HOME/bin` - Thư mục nhị phân tiêu chuẩn của người dùng (nếu tồn tại hoặc có thể tạo)
-4. `$HOME/.opencode/bin` - Mặc định dự phòng
-
-```bash
-# Ví dụ
-OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
-XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
-```
-
-### Agents (Đại diện)
-
-OpenCode bao gồm hai agent được tích hợp sẵn mà bạn có thể chuyển đổi bằng phím `Tab`.
-
-- **build** - Agent mặc định, có toàn quyền truy cập cho công việc lập trình
-- **plan** - Agent chỉ đọc dùng để phân tích và khám phá mã nguồn
-  - Mặc định từ chối việc chỉnh sửa tệp
-  - Hỏi quyền trước khi chạy các lệnh bash
-  - Lý tưởng để khám phá các codebase lạ hoặc lên kế hoạch thay đổi
-
-Ngoài ra còn có một subagent **general** dùng cho các tìm kiếm phức tạp và tác vụ nhiều bước.
-Agent này được sử dụng nội bộ và có thể gọi bằng cách dùng `@general` trong tin nhắn.
-
-Tìm hiểu thêm về [agents](https://opencode.ai/docs/agents).

-### Tài liệu
-
-Để biết thêm thông tin về cách cấu hình OpenCode, [**hãy truy cập tài liệu của chúng tôi**](https://opencode.ai/docs).
-
-### Đóng góp
-
-Nếu bạn muốn đóng góp cho OpenCode, vui lòng đọc [tài liệu hướng dẫn đóng góp](./CONTRIBUTING.md) trước khi gửi pull request.
-
-### Xây dựng trên nền tảng OpenCode
-
-Nếu bạn đang làm việc trên một dự án liên quan đến OpenCode và sử dụng "opencode" như một phần của tên dự án, ví dụ "opencode-dashboard" hoặc "opencode-mobile", vui lòng thêm một ghi chú vào README của bạn để làm rõ rằng dự án đó không được xây dựng bởi đội ngũ OpenCode và không liên kết với chúng tôi dưới bất kỳ hình thức nào.
-
-### Các câu hỏi thường gặp (FAQ)
-
-#### OpenCode khác biệt thế nào so với Claude Code?
-
-Về mặt tính năng, nó rất giống Claude Code. Dưới đây là những điểm khác biệt chính:
-
-- 100% mã nguồn mở
-- Không bị ràng buộc với bất kỳ nhà cung cấp nào. Mặc dù chúng tôi khuyên dùng các mô hình được cung cấp qua [OpenCode Zen](https://opencode.ai/zen), OpenCode có thể được sử dụng với Claude, OpenAI, Google, hoặc thậm chí các mô hình chạy cục bộ. Khi các mô hình phát triển, khoảng cách giữa chúng sẽ thu hẹp lại và giá cả sẽ giảm, vì vậy việc không phụ thuộc vào nhà cung cấp là rất quan trọng.
-- Hỗ trợ LSP ngay từ đầu
-- Tập trung vào TUI (Giao diện người dùng dòng lệnh). OpenCode được xây dựng bởi những người dùng neovim và đội ngũ tạo ra [terminal.shop](https://terminal.shop); chúng tôi sẽ đẩy giới hạn của những gì có thể làm được trên terminal lên mức tối đa.
-- Kiến trúc client/server. Chẳng hạn, điều này cho phép OpenCode chạy trên máy tính của bạn trong khi bạn điều khiển nó từ xa qua một ứng dụng di động, nghĩa là frontend TUI chỉ là một trong những client có thể dùng.

-
-### 参与贡献
-
-如有兴趣贡献代码，请在提交 PR 前阅读 [贡献指南 (Contributing Docs)](./CONTRIBUTING.md)。
-
-### 基于 OpenCode 进行开发
-
-如果你在项目名中使用了 “opencode”（如 “opencode-dashboard” 或 “opencode-mobile”），请在 README 里注明该项目不是 OpenCode 团队官方开发，且不存在隶属关系。
-
-### 常见问题 (FAQ)
-
-#### 这和 Claude Code 有什么不同？
-
-功能上很相似，关键差异：
-
-- 100% 开源。
-- 不绑定特定提供商。推荐使用 [OpenCode Zen](https://opencode.ai/zen) 的模型，但也可搭配 Claude、OpenAI、Google 甚至本地模型。模型迭代会缩小差异、降低成本，因此保持 provider-agnostic 很重要。
-- 内置 LSP 支持。
-- 聚焦终端界面 (TUI)。OpenCode 由 Neovim 爱好者和 [terminal.shop](https://terminal.shop) 的创建者打造，会持续探索终端的极限。
-- 客户端/服务器架构。可在本机运行，同时用移动设备远程驱动。TUI 只是众多潜在客户端之一。

-### 常見問題 (FAQ)
-
-#### 這跟 Claude Code 有什麼不同？
-
-在功能面上與 Claude Code 非常相似。以下是關鍵差異：
-
-- 100% 開源。
-- 不綁定特定的服務提供商。雖然我們推薦使用透過 [OpenCode Zen](https://opencode.ai/zen) 提供的模型，但 OpenCode 也可搭配 Claude, OpenAI, Google 甚至本地模型使用。隨著模型不斷演進，彼此間的差距會縮小且價格會下降，因此具備「不限廠商 (provider-agnostic)」的特性至關重要。
-- 內建 LSP (語言伺服器協定) 支援。
-- 專注於終端機介面 (TUI)。OpenCode 由 Neovim 愛好者與 [terminal.shop](https://terminal.shop) 的創作者打造。我們將不斷挑戰終端機介面的極限。
-- 客戶端/伺服器架構 (Client/Server Architecture)。這讓 OpenCode 能夠在您的電腦上運行的同時，由行動裝置進行遠端操控。這意味著 TUI 前端只是眾多可能的客戶端之一。

-# Security
-
-## IMPORTANT
-
-We do not accept AI generated security reports. We receive a large number of
-these and we absolutely do not have the resources to review them all. If you
-submit one that will be an automatic ban from the project.
-
-## Threat Model
-
-### Overview
-
-OpenCode is an AI-powered coding assistant that runs locally on your machine. It provides an agent system with access to powerful tools including shell execution, file operations, and web access.
-
-### No Sandbox
-
-OpenCode does **not** sandbox the agent. The permission system exists as a UX feature to help users stay aware of what actions the agent is taking - it prompts for confirmation before executing commands, writing files, etc. However, it is not designed to provide security isolation.
-
-If you need true isolation, run OpenCode inside a Docker container or VM.
-
-### Server Mode
-
-Server mode is opt-in only. When enabled, set `OPENCODE_SERVER_PASSWORD` to require HTTP Basic Auth. Without this, the server runs unauthenticated (with a warning). It is the end user's responsibility to secure the server - any functionality it provides is not a vulnerability.
-
-### Out of Scope
-
-| Category                        | Rationale                                                               |
-| ------------------------------- | ----------------------------------------------------------------------- |
-| **Server access when opted-in** | If you enable server mode, API access is expected behavior              |
-| **Sandbox escapes**             | The permission system is not a sandbox (see above)                      |
-| **LLM provider data handling**  | Data sent to your configured LLM provider is governed by their policies |
-| **MCP server behavior**         | External MCP servers you configure are outside our trust boundary       |
-| **Malicious config files**      | Users control their own config; modifying it is not an attack vector    |

-# Reporting Security Issues
-
-We appreciate your efforts to responsibly disclose your findings, and will make every effort to acknowledge your contributions.
-
-To report a security issue, please use the GitHub Security Advisory ["Report a Vulnerability"](https://github.com/anomalyco/opencode/security/advisories/new) tab.
-
-The team will send a response indicating the next steps in handling your report. After the initial reply to your report, the security team will keep you informed of the progress towards a fix and full announcement, and may ask for additional information or guidance.

 response

Align with Python connector's Field(name, field_type, ..., nullable).
- Add nullable to LhFieldType and ColumnSchema interfaces
- Parse nullable from API field.type.nullable (default true)
- Cursor.description now includes nullable

Subject: [PATCH 275/521] feat(cz-cli): gateway command - use portal token with
 gateway admin APIs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Switch all gateway commands to use portal token (X-Clickzetta-Token) directly
  against /llm-gateway-admin/v2/* endpoints — gateway accepts it
- Add gwRequest wrapper with --debug roundtrip logging (path, body, latency, response)
- Add getGatewayContext with userName field for portal fallback endpoints
- Add 'upsert' command (idempotent create-or-update) alongside 'create' (which
  now rejects if alias already exists)
- Fix response data extraction (resp.data is the array directly, not nested)
- Fix field name mapping for Jackson lowercase (vapiKeyAlias/vapiKeyMasked)
- Retain portal endpoint code (portalGet/PORTAL_API) as fallback

Subject: [PATCH 277/521] fix(release): prevent channel pointer downgrade on
 re-publish

Both cos-promote.mjs and cos-release.mjs now read the current channel
version before writing. If the version being published is lower than
the current pointer, promote is refused (cos-promote throws, cos-release
skips with a warning). This prevents re-building an older tag from
accidentally rolling back stable/nightly.

Subject: [PATCH 285/521] fix: COS upload retry + global acceleration + update
 via install script

- Add withRetry helper for COS uploads (3 retries, exponential backoff)
- Enable global acceleration by default (COS_ACCELERATE env var)
- Always upgrade via install script instead of npm (avoids mirror sync delay)

Subject: [PATCH 287/521] fix(commands): halt handlers after emitting error or

error() and success() only set process.exitCode and write output; they
do not stop execution. Add early returns so handlers don't continue with
invalid state or emit duplicate output after reporting a result.

Subject: [PATCH 288/521] fix(task): fail fast on invalid dependencies and halt
 after errors

Extract dep-tasks parsing into parseDependencyTasks, which throws a
HandledCliError on invalid input instead of reporting and then saving a
partially-stripped config. Add early returns after validation errors so
save-config and flow subcommands abort before calling the SDK.

Subject: [PATCH 289/521] fix(profile): reassign or clear default_profile when
 deleting it

Deleting the profile referenced by default_profile left a dangling
reference. Point it at a remaining profile, or drop the key when none
remain.

Subject: [PATCH 290/521] feat(setup): scope LLM config under the profile name

Store credential-derived LLM settings under the profile name instead of
a hardcoded "clickzetta" key, and default default_llm to the profile
name. Keeps LLM config per-profile and consistent across packages.

Subject: [PATCH 291/521] fix(cron): honor non-zero start minute in interval
 encoding

A non-zero start minute was ignored, so 'every N minutes from minute M'
encoded as */N (from 0) instead of M/N. Emit startM/gap when startM != 0.

Subject: [PATCH 292/521] fix(formatter): render empty table header and fix CSV
 cell encoding

formatTable now renders the header and separator for empty result sets
instead of falling back to pretty JSON. formatCsvCell no longer JSON-wraps
number/bool/null-looking strings (CSV is typeless), quoting only the
literal "NULL" string to disambiguate it from the null sentinel.

Subject: [PATCH 293/521] fix(runtime): pass agent-runtime flag in-process
 instead of via env

CLICKZETTA_AGENT_RUNTIME in process.env was inherited by child processes,
so a nested cz-cli launched from the agent's bash tool re-entered the
agent runtime. Pass it as a main() argument to scope it to the in-process
call.

Subject: [PATCH 295/521] feat(tui): add /sql command to run SQL like cz-cli
 sql

Adds a /sql slash command that executes SQL via session.shell, equivalent
to `cz-cli sql`. Simple single-line queries are inlined (readable); SQL
containing ' " ` $ \ or newlines is written to a temp file and run with
--file to avoid shell-quoting corruption.

Subject: [PATCH 297/521] refactor(cli): remove misleading config alias for
 agent llm

config aliased/routed to agent llm, colliding with the universal
git config-style idiom. Remove the alias and the top-level/agent config
routing; LLM management stays on llm / agent llm.

Subject: [PATCH 299/521] chore(cli): remove unused SKILL.md template/generator
 pipeline

The committed skills are hand-maintained; the template/generator had
drifted and was no longer the source of the shipped SKILL.md files.
Drop SKILL.template.md, skill-generator.ts, and ai-guide's
--generate-skill/--check-skill options; keep the command-reference output.

-# cz-cli Skill
-
-> [!IMPORTANT]
-> **Fallback**: If `cz-cli` command not present, check for a bundled binary at `scripts/<platform>/cz-cli` (e.g. `scripts/macos-arm64/cz-cli`, `scripts/linux-x86_64/cz-cli`, `scripts/windows-x86_64/cz-cli.exe`). If found, use its absolute path directly. Otherwise run `pip3 install cz-cli -U` then use `cz-cli` from PATH.
-
-## AI Agent Behavior Rules
-
-> [!IMPORTANT]
-> Read these rules before invoking any command.
-
-### Rule 0 — Initialize connection profile before first use
-
-When any command returns error code `NO_PROFILE`, run `cz-cli setup --credential <base64>` if the credential string is available, or read `references/profile-setup.md` and follow the onboarding steps there. Always use the **AskUserQuestion tool** — never ask via plain text.
-
-### Rule 1 — Clarify intent before any state-changing operation
-
-When a task involves an operation that changes system state (publishing a schedule, taking a task offline, triggering a run, deleting an object, etc.):
-
-**Do NOT proceed without** explicitly understanding the user's intent on all three points:
-1. **Target**: Which task / table / run instance?
-2. **Purpose**: Why does this need to happen now?
-3. **Side-effect acknowledgment**: Does the user understand the impact (historical re-runs, schedule interruption, permanent deletion, etc.)?
-
-Use the **AskUserQuestion tool** (not plain text) to confirm with the user, then wait for an explicit reply before executing.
-
-Consult **Command Risk Reference** below to determine whether a command qualifies as state-changing.
-
-
-### Rule 2 — Route to companion skill BEFORE acting (MUST)
-
-> [!IMPORTANT]
-> Check this routing table **before** executing any command or writing any code.
-> If the user intent matches a trigger below, **MUST** invoke the listed skill immediately and stop processing in cz-cli.
-
-The following companion skills are bundled with `cz-cli`:
-
-- **lakehouse-python-sdk** — Lakehouse Python/Shell task engineering: develop, rewrite, optimize, troubleshoot. Covers connector, BulkLoad, IGS, Studio params, datasource, and CREATE TABLE DDL; MUST trigger on: develop/write/create/modify/rewrite/optimize Python or Shell task; BulkLoad batch upload; IGS realtime ingest; connector query/write; Python task error/diagnosis; CREATE TABLE / partition / bucket / index DDL.
-- **lakehouse-doc** — ClickZetta Lakehouse official documentation. Covers SQL syntax, data types, functions, DDL/DML commands, dynamic tables, materialized views, access control, VCluster, data lake, AI functions, etc. When the user writes or asks about SQL syntax or Lakehouse dialect specifics, **MUST** consult lakehouse-doc skill references first to ensure accuracy.
-
-**If no row matches**: proceed with cz-cli commands directly.
-
-### Rule 3 — Development ends at save; execution requires separate authorization
-
-When the user says "develop", "write", "create", or "modify" a task, the work is **complete once the script is saved successfully**.
-After saving, tell the user: "The task has been saved as a draft. Scheduling is not yet active. Let me know explicitly if you want to publish or execute it."
-
-**Do NOT** auto-publish, auto-trigger execution, or auto-submit a backfill after saving — even if those steps seem like the logical next thing. Every phase that produces a real side effect requires the user to express intent and grant authorization separately.
-
-**Exception**: If the user's original request *explicitly* authorized all subsequent steps (e.g. "create and immediately go live", "develop and run it now"), AND Rule 1 already confirmed that intent at the start, the Agent may proceed through the authorized steps without stopping again at each phase. Do not re-ask for confirmation that was already given.
-
-### Rule 3.1 — 补数/回填/重跑历史数据 → `runs refill` (NOT `task`)
-
-When the user says "补数", "回填", "重跑历史", "backfill", "re-run historical", or "re-process date range":
-- **MUST** use `cz-cli runs refill <task> --from YYYY-MM-DD --to YYYY-MM-DD [-y]`
-- This command is under `runs`, **NOT** under `task` — do not look for it in task subcommands
-- Requires the task to already be published (online); draft tasks cannot be backfilled
-
-### Rule 4 — Paginated results are not complete data
-
-All `list` commands return only page 1 by default (typically 10 items). The `ai_message` field in the response contains the total count and the command to fetch the next page — treat it as the authoritative next-step hint and follow it. Never treat a first-page result as the full dataset.
-
-**Pagination termination rules**:
-- If the user only needs "latest / recent N items": stop after page 1, do not paginate.
-- If the user needs the full dataset: paginate until `ai_message` no longer contains a next-page hint.
-- **Safety limit**: auto-paginate at most **3 pages** (≈ 30 items). If more exist, surface the next-page command to the user and ask whether to continue.
-
-### Rule 5 — Always pass explicit task type when creating tasks
-
-When creating a task with `cz-cli task create`, **always** pass `--type` explicitly (`SQL` / `PYTHON` / `SHELL` / `SPARK` / `FLOW`).
-The Python SDK(connector/igs/bulkload) is using from clickzetta import connect instead of Zettapark's session.
-
-- **MUST NOT** rely on default task type.
-- If user intent says “Python task”, command must include `--type PYTHON`.
-- If `--type FLOW`, immediately switch to Rule 6 — use Flow-specific commands exclusively.
-
-### Rule 6 — Flow nodes use Flow-specific tools exclusively
-
-When the operation target is a Flow task or any of its child nodes (`task_type=500`, or user mentions "composite task / flow / workflow"):
-
-- **MUST** use Flow-specific commands: `task flow node-detail`, `task flow node-save`, `task flow node-save-config`, `task flow bind`, `task flow submit`, etc.
-- **MUST NOT** use `task save`, `task save-config`, `task detail`, or `task online` on Flow child nodes — these tools are for regular (non-Flow) tasks only and will produce incorrect results or errors.
-- **Decision rule**: if `task_type == 500` OR the user mentions flow/workflow context → use `task flow *` commands unconditionally.
-
-### Rule 7 — Always display studio_url in final report
-
-Responses from `task`, `runs`, and `executions` commands may include a `studio_url` field. When present, surface it in the end to the user so they can open the resource directly in Studio.
-
-Display as a Markdown hyperlink: `[View in Studio](https://...)`. Show all studio_url values returned across all commands in the same response — do not deduplicate.
-
-### Rule 8 — Maximize execution efficiency: parallel and chained commands
-
-**Independent commands → parallel.  Dependent commands → chain with `--field`.**
-
-```bash
-# Async SQL: submit → poll → fetch result → preview first rows
-JOB=$(cz-cli sql "SELECT * FROM orders LIMIT 100" --field job_id) && cz-cli job status $JOB --format toon && cz-cli job result $JOB --format toon | head -12

-Key tools:
-- `--field <name>` — extract one value as raw text: `cz-cli sql "..." --field job_id` → `2026042818122957849079780`
-- `--format toon` — line-per-field output, works with `grep`/`head`
-- `--format json` — single-line JSON, parse in code only (do NOT pipe to grep/head)
-
-**Shortcut**: Use `cz-cli sql --sync "..." > /tmp/res.json` to force synchronous execution (waits for results inline). Prefer `--sync` for simple/fast queries.
-
-## Command Quick Reference
-
-### Connection & Profile
-- `cz-cli profile create <name> --username U --password P --instance I --workspace W` — Create profile
-- `cz-cli profile create <name> --pat TOKEN --instance I --workspace W` — Create profile with PAT
-- `cz-cli profile list` — List all profiles
-- `cz-cli profile status` — Test connection, show workspace/schema
-- `cz-cli profile use <name>` — Set default profile
-- `cz-cli profile delete <name>` — Delete a profile
-- `cz-cli profile discover --studio-url URL --username U --password P` — Discover regions/instances
-
-### SQL Execution
-- `cz-cli sql "SELECT * FROM t LIMIT 10"` — Execute SQL query
-- `cz-cli sql -f query.sql` — Execute SQL from file
-- `cz-cli sql --write "INSERT INTO t VALUES (...)"` — Write operation (requires --write)
-- `cz-cli sql --async "SELECT count(*) FROM big_table"` — Async execution, returns job_id
-- `cz-cli sql --sync "SELECT 1"` — Force synchronous execution
-- `cz-cli sql -e "SELECT * FROM t WHERE id = %(id)s" --variable id=123` — Variable substitution
-
-### Job Management (async SQL results)
-- `cz-cli job status <job_id>` — Check job status
-- `cz-cli job result <job_id>` — Fetch result set (waits if running, limited to 100 rows)
-- `cz-cli job result --no-limit <job_id>` — Fetch full result set
-
-### Schema & Table
-- `cz-cli schema list` / `cz-cli schema describe <name>` / `cz-cli schema create <name>` / `cz-cli schema drop <name>`
-- `cz-cli table list [--schema S] [--like 'pattern%']` / `cz-cli table describe <name>` / `cz-cli table preview <name> [--limit N]`
-- `cz-cli table stats <name>` / `cz-cli table history [name]` / `cz-cli table create "DDL"` / `cz-cli table drop <name>`
-
-### Workspace
-- `cz-cli workspace current` — Show current workspace
-- `cz-cli workspace use <name> [--persist]` — Switch workspace
-
-### Task Scheduling (Studio)
-- `cz-cli task list [--page N --page-size N]` — List tasks
-- `cz-cli task create <name> --type SQL|PYTHON|SHELL|SPARK|FLOW --folder F` — Create task
-- `cz-cli task content <name_or_id>` — Get task script, config and params (draft); response includes `params` array with `paramType=system` (built-in params / time expressions) or `paramType=manual` (constants)
-- `cz-cli task save-content <name_or_id> --file script.sql [--params '{"key":"val","dt":"bizdate","yd":"$[yyyy-MM-dd,-1d]"}']` — Save script and optionally set params; system params (bizdate, sys_biz_day, sys_biz_datetime, sys_plan_day, sys_plan_datetime, sys_plan_timestamp, sys_task_id, sys_task_name, sys_task_owner) and time expressions starting with `$[` are auto-detected as `paramType=system`
-- `cz-cli task save-config <name_or_id> --cron "0 0 8 * * ? *"` — Save schedule (sec min hour day month week year)
-- `cz-cli task online <name_or_id> -y` — Publish task
-- `cz-cli task offline <name_or_id> -y` — Take offline (IRREVERSIBLE)
-- `cz-cli task execute <name_or_id> [--param KEY=VAL ...]` — Ad-hoc execution; auto-loads saved `manual` params as defaults (system params like `bizdate` are NOT auto-injected in adhoc mode — pass them explicitly via `--param`); warns if unresolved `${placeholders}` remain after merge (SQL tasks will fail, Python/Shell silently keep literal strings)
-- `cz-cli task flow dag <flow>` / `task flow create-node` / `task flow bind` / `task flow submit` — Flow operations
-
-### Runs & Attempts
-- `cz-cli runs list [--task T --status S --run-type SCHEDULE|REFILL --from D --to D]`
-- `cz-cli runs detail <run_id_or_task>` / `cz-cli runs logs <run_id_or_task>` / `cz-cli runs wait <id> --timeout N`
-- `cz-cli runs refill <task> --from D --to D [-y]` — **补数/回填**: re-run scheduled instances for a historical date range (task must be online). `D` accepts `YYYY-MM-DD` (day boundary: `--from` = start of day, `--to` = 23:59:59) or `YYYY-MM-DDTHH:MM:SS` for exact datetime — **use ISO datetime for hourly/minutely tasks** to avoid missing instances
-- `cz-cli attempts list <run_id_or_task>` / `cz-cli attempts log <run_id_or_task> [--attempt-id N]`
-
-### Agent (AI Agent)
-- `cz-cli agent run "<prompt>" [--session ID]` — Run AI agent with a natural-language prompt
-- `cz-cli agent session status <session_id> [--wait]` — Check session progress; by default it returns the current status once, and with `--wait` it keeps waiting and streams progress until completion or timeout
-- `cz-cli agent llm` — Manage LLM providers

Subject: [PATCH 329/521] fix(agent): ensure rotated key is picked up on retry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two bugs prevented the conversation from continuing after key rotation:

1. config.invalidate() triggered Instance.disposeAll() asynchronously, which
   raced with the retry and re-invalidated the freshly rebuilt provider state,
   causing the SDK to miss the new API key. Add config.invalidateCache() that
   only clears the global config cache and Config InstanceState without
   disposing instances.

2. No guard against repeated rotation — if the retry still failed (e.g. due
   to the race in bug 1), recoverRotation would loop infinitely creating new
   keys. Add a per-stream flag that limits rotation to one attempt.

Subject: [PATCH 344/521] feat(cli): add --limit to datasource subcommands;
 trim runs list to snake_case fields

- datasource catalogs/objects/sample: add --limit (default 50) with client-side truncation and a Showing N of M hint when capped
- runs list: drop unmapped camelCase API noise (extraParams, applicationEnv, groupNumber, complementTaskId, ...), keep only snake_case fields to reduce agent context

 ## Key Rules
 
 1. **SQL is async by default**. Use `--sync` for SELECT when you need data immediately.
-2. **Write operations require `--write` flag** (INSERT/UPDATE/DELETE/CREATE/DROP).
+2. **Write operations ALWAYS require `--write` flag** — this includes ALL DDL (CREATE, ALTER, DROP, CREATE DYNAMIC TABLE, CREATE MATERIALIZED VIEW) and ALL DML (INSERT, UPDATE, DELETE, MERGE INTO, COPY INTO). Without `--write`, the command will be rejected. Always add it proactively.
 3. **Always pass `--type` when creating tasks** (SQL/PYTHON/SHELL/SPARK/FLOW).
 4. **Flow tasks use `task flow *` commands exclusively** — never use `task save-content` or `task deploy` on flow nodes.
 5. **Paginated results**: `list` commands return page 1 only. Check `ai_message` in response for next-page hints.

Subject: [PATCH 348/521] refactor(agent): remove source_profile, use current
 profile for key rotation

- Remove source_profile field from llm entries entirely
- Key rotation now uses current profile (CZ_PROFILE > default_profile)
  to authenticate with gateway API and resolve ai_gateway_url
- Add ai_gateway_url to profile entry during setup --credentials
- Implement inferAiGatewayUrl with OP deployment routing (from aimeshEndpoint)
- Add normalizeGatewayUrl to ensure /gateway/v1 suffix
- Rotation creates new llm entry named after profile (with _N dedup)
- Rotation failures surface clearly in TUI error message
- LLM request errors now prefixed with "LLM request failed:"

Subject: [PATCH 350/521] feat(update): add --target option for version
 downgrade

Allow users to install a specific older version via:
  cz-cli update --target 0.5.1

- Add --target/-t option to update command
- Skip version check when target is explicitly specified
- Add 'target'/'t' to KNOWN_FLAGS in cli.ts

- model list 支持传 alias（自动解析为 key value），参数改名为 [ref]
- model list 输出精简为 modelIdentifier/modelName/modelDesc
- key list 输出隐藏内部 id 字段
- set-quota 帮助说明 quota 单位为 token 数及周期重置逻辑
- cz-cli-inner prompt 丰富 ai-gateway 所有子命令参数说明
- 新增规则：Lakehouse SQL 方言限制 + 循环检测跳出提示

 8. **On `NO_PROFILE` error**: guide user to run `cz-cli setup`.
 9. **补数/回填/重跑历史数据 → `runs refill`**: when user says "补数", "回填", "重跑历史", "backfill", "re-run historical data", use `cz-cli runs refill <task> --from YYYY-MM-DD --to YYYY-MM-DD`. This is under `runs`, NOT `task`.
 10. **Use a file for SQL with special characters**: if the SQL contains quotes, `$`, backticks, `\`, or newlines, run `cz-cli sql -f <file>` instead of inline `cz-cli sql "..."` (the shell corrupts inline SQL).
+11. **Lakehouse SQL dialect ONLY**: cz-cli connects to ClickZetta Lakehouse, NOT Snowflake or Databricks. Do NOT use Snowflake syntax (e.g. `SHOW STAGES IN SCHEMA xxx`). Lakehouse uses `SHOW VOLUMES IN xxx` (no `SCHEMA` keyword). When unsure about syntax, consult the **lakehouse-doc** skill BEFORE running SQL — guessing Snowflake/Databricks syntax will fail.
+12. **Break out of loops immediately**: If the same command fails 2+ times, or you notice you are repeating similar actions without progress, STOP. Do NOT retry with minor variations. Instead: explain what went wrong, state what you tried, and ask the user for guidance or try a fundamentally different approach.

 ## Key Rules
 
-1. **SQL is async by default**. Use `--sync` for SELECT when you need data immediately.
-2. **Write operations ALWAYS require `--write` flag** — this includes ALL DDL (CREATE, ALTER, DROP, CREATE DYNAMIC TABLE, CREATE MATERIALIZED VIEW) and ALL DML (INSERT, UPDATE, DELETE, MERGE INTO, COPY INTO). Without `--write`, the command will be rejected. Always add it proactively.
-3. **Always pass `--type` when creating tasks** (SQL/PYTHON/SHELL/SPARK/FLOW).
-4. **Flow tasks use `task flow *` commands exclusively** — never use `task save-content` or `task deploy` on flow nodes.
-5. **Paginated results**: `list` commands return page 1 only. Check `ai_message` in response for next-page hints.
-6. **State-changing operations** (deploy/undeploy/execute/delete/refill): confirm intent with user first.
-7. **Multi-environment**: use `--profile <name>` to target a specific environment.
-8. **On `NO_PROFILE` error**: guide user to run `cz-cli setup`.
-9. **补数/回填/重跑历史数据 → `runs refill`**: when user says "补数", "回填", "重跑历史", "backfill", "re-run historical data", use `cz-cli runs refill <task> --from YYYY-MM-DD --to YYYY-MM-DD`. This is under `runs`, NOT `task`.
-10. **Use a file for SQL with special characters**: if the SQL contains quotes, `$`, backticks, `\`, or newlines, run `cz-cli sql -f <file>` instead of inline `cz-cli sql "..."` (the shell corrupts inline SQL).
-11. **Lakehouse SQL dialect ONLY**: Before generating, modifying, validating, explaining, or running Lakehouse SQL, load **lakehouse-doc-en** and ground the SQL in the documented ClickZetta Lakehouse dialect. cz-cli connects to ClickZetta Lakehouse, NOT Snowflake or Databricks. Do NOT use Snowflake syntax (e.g. `SHOW STAGES IN SCHEMA xxx`). Lakehouse uses `SHOW VOLUMES IN xxx` (no `SCHEMA` keyword). Guessing Snowflake/Databricks syntax will fail.
-12. **Break out of loops immediately**: If the same command fails 2+ times, or you notice you are repeating similar actions without progress, STOP. Do NOT retry with minor variations. Instead: explain what went wrong, state what you tried, and ask the user for guidance or try a fundamentally different approach.

+**Break out of loops immediately**: If the same command fails 2+ times, or you notice you are repeating similar actions without progress, STOP. Do NOT retry with minor variations. Instead: explain what went wrong, state what you tried, and ask the user for guidance or try a fundamentally different approach.

Subject: [PATCH 366/521] refactor: unify skill installation across all install
 paths

- install.sh: preserve skills/ from archive, install to ~/.clickzetta/skills/.builtin/
- postinstall.js: clear .builtin/ entirely before repopulating, install all skills
  (including cz-cli) to .builtin/ instead of agent dirs, add cz-agent wrapper
- update command: explicitly install skills after upgrade as safety net
- All paths clean up legacy skills from ~/.claude, ~/.kiro, ~/.cursor etc.

+license: MIT
+compatibility: Requires openspec CLI.

+---
+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - Context file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read the files listed in `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! Ready to archive this change.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.2.0"
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**
+```

+
+---
+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   | Insight Type | Where to Capture |
+   |--------------|------------------|
+   | New requirement discovered | `specs/<capability>/spec.md` |
+   | Requirement changed | `specs/<capability>/spec.md` |
+   | Design decision made | `design.md` |
+   | Scope changed | `proposal.md` |
+   | New work identified | `tasks.md` |
+   | Assumption invalidated | Relevant artifact |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Handling Different Entry Points

+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change proposal
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+
+# source-command-opsx-apply
+
+Use this skill when the user asks to run the migrated source command `opsx-apply`.
+
+## Command Template
+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - Context file paths (varies by schema)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read the files listed in `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```

+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+# source-command-opsx-archive
+
+Use this skill when the user asks to run the migrated source command `opsx-archive`.
+
+## Command Template
+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Spec sync status (synced / sync skipped / no delta specs)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success (No Delta Specs)**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** No delta specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success With Warnings**
+
+```
+## Archive Complete (with warnings)
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** Sync skipped (user chose to skip)
+
+**Warnings:**
+- Archived with 2 incomplete artifacts
+- Archived with 3 incomplete tasks
+- Delta spec sync was skipped (user chose to skip)
+
+Review the archive if this was not intentional.
+```
+
+**Output On Error (Archive Exists)**
+
+```
+## Archive Failed
+
+**Change:** <change-name>
+**Target:** openspec/changes/archive/YYYY-MM-DD-<name>/
+
+Target archive directory already exists.
+
+**Options:**
+1. Rename the existing archive
+2. Delete the existing archive if it's a duplicate
+3. Wait until a different date to archive
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+---
+
+# source-command-opsx-explore
+
+Use this skill when the user asks to run the migrated source command `opsx-explore`.
+
+## Command Template
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+**Surface risks and unknowns**
+- Identify what could go wrong
+- Find gaps in understanding
+- Suggest spikes or investigations
+
+---
+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   | Insight Type | Where to Capture |
+   |--------------|------------------|
+   | New requirement discovered | `specs/<capability>/spec.md` |
+   | Requirement changed | `specs/<capability>/spec.md` |
+   | Design decision made | `design.md` |
+   | Scope changed | `proposal.md` |
+   | New work identified | `tasks.md` |
+   | Assumption invalidated | Relevant artifact |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+Use this skill when the user asks to run the migrated source command `opsx-propose`.
+
+## Command Template
+
+Propose a new change - create the change and generate all artifacts in one step.
+
+I'll create a change with artifacts:
+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Input**: The argument after `/opsx:propose` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

Subject: [PATCH 369/521] feat(agent): add anti-hallucination rule for URLs and
 identifiers

Instruct the cz-cli agent to surface links and IDs exactly as they appear in command output, and never hand-edit, truncate, extrapolate, or invent them.

 **Use a file for SQL with special characters**: if the SQL contains quotes, `$`, backticks, `\`, or newlines, run `cz-cli sql -f <file>` instead of inline `cz-cli sql "..."` (the shell corrupts inline SQL).
 **Lakehouse SQL dialect ONLY**: cz-cli connects to ClickZetta Lakehouse, NOT Snowflake or Databricks. Do NOT use Snowflake syntax (e.g. `SHOW STAGES IN SCHEMA xxx`). Lakehouse uses `SHOW VOLUMES IN xxx` (no `SCHEMA` keyword). When unsure about syntax, consult the **lakehouse-doc** skill BEFORE running SQL — guessing Snowflake/Databricks syntax will fail.
 **Break out of loops immediately**: If the same command fails 2+ times, or you notice you are repeating similar actions without progress, STOP. Do NOT retry with minor variations. Instead: explain what went wrong, state what you tried, and ask the user for guidance or try a fundamentally different approach.

Subject: [PATCH 378/521] fix(update): isolate release channel and fix
 auto-update for stable

Auto-update was gated to the nightly channel and reused opencode's build-time InstallationChannel, so stable installs never auto-updated. Version resolution for npm-family installs also queried the npm registry instead of the cz-cli.ai channel API.

- Introduce an isolated ReleaseChannel (stable default / nightly), resolved from CZ_CHANNEL env -> install.json.channel -> stable; never reads InstallationChannel.
- Channel no longer gates whether auto-update runs; it only selects the stream. Dev/local builds stay excluded via the semver guard.
- Version resolution is always channel-based via cz-cli.ai (stable -> /api/stable, nightly -> /api/nightly); install method only selects the upgrade command, with install-script fallback when npm lacks the version.
- writeInstallMetadata preserves the existing channel instead of stamping InstallationChannel.
- All install/update entry points create-or-update ~/.clickzetta/install.json with the channel: setup.sh, install.sh, npm postinstall, cz-cli update, auto-update; defaults unified to stable.
- Thread CZ_CHANNEL through package-manager and install-script upgrades.
- Add tests for channel resolution, channel-not-gating, channel-based version source, and setup.sh metadata; document the contract as OpenSpec capabilities (release-channel, auto-update).

+## Context
+
+cz-cli is built on opencode. opencode injects a build-time `InstallationChannel` constant (`CLICKZETTA_CHANNEL`) that is deeply wired into the runtime: per-channel SQLite DB isolation (`getChannelPath()`), OpenTelemetry `deployment.environment.name`, `USER_AGENT`, and dev-mode detection (`isLocal()`/`isPreview()`, plugin version pinning). The update logic reused this same constant to decide the release stream and to gate auto-update, and the gate required `channel === "nightly"`. As a result, `stable` installs never auto-updated, and a channel rename in an unrelated commit silently regressed the behavior.
+
+Separately, channel values were inconsistent across install paths (`latest` in npm postinstall and `setup.sh` default; `stable` in the COS bootstrap; `nightly` for dev), and `scripts/install.sh` did not write `~/.clickzetta/install.json` at all, so the installed channel could not be recovered by `cz-cli update`.
+
+## Goals / Non-Goals
+
+**Goals:**
+- A dedicated cz-cli "release channel" concept, fully isolated from opencode's `InstallationChannel`.
+- Auto-update works for the normal (`stable`) release, not just `nightly`.
+- One consistent channel vocabulary (`stable` default, `nightly`) and one consistent `install.json` schema written by every install/update entry point.
+- Make the invariants testable so future renames cannot silently regress behavior.
+
+**Non-Goals:**
+- Changing opencode's `InstallationChannel` or any of its consumers (DB path, telemetry, dev detection, plugin pinning).
+- Adding new channels beyond `stable`/`nightly`.
+- Changing how install scripts are generated/served (COS bootstrap, GitHub installer); only the metadata they persist and their default channel.
+
+## Decisions
+
+**D1 — Separate release channel, not a reuse of `InstallationChannel`.**
+The release channel is resolved at runtime from `CZ_CHANNEL` env → `~/.clickzetta/install.json` `channel` → `stable`. The persisted channel is authored by the installer that performed the install (it knows the stream), and read back by update/auto-update. Rationale: `InstallationChannel` carries unrelated runtime semantics (data isolation, telemetry env); coupling release decisions to it caused the regression and risked cross-effects. Alternative considered: add a second build-time constant — rejected because the installer, not the binary build, is the authority for "which stream is this machine tracking," and it must survive binary replacement.
+
+**D2 — Channel selects the stream; it does not gate whether auto-update runs.**
+Auto-update enablement is decided by: not disabled via env/config, command not in skip-list (`setup`/`update`/`uninstall`/`--help`/`--version`), `semver.valid(version)` (excludes dev/local builds), supported install method, and the check interval. Channel only maps to endpoints/scripts (`stable` → `api/stable` + `install.sh`; `nightly` → `api/nightly` + `install-nightly.sh`). Rationale: the previous channel gate was the root cause; the dev/local guard already exists via invalid semver of `InstallationVersion === "local"`.
+
+**D3 — `writeInstallMetadata` preserves the existing channel.**
+Instead of stamping `InstallationChannel`, it reads the current `install.json`, keeps its (coerced) channel, defaulting to `stable`, and lets explicit callers override. This severs the bridge to opencode's channel while keeping the channel sticky across updates.
+
+**D4 — Two-file state model is the contract for "did auto-update run".**
+`install.json` is channel/identity memory written by every entry point. `update-check.json` (under XDG state) is written only by the auto-update path and records `last_checked_at`/`last_result`/`latest_version`. Diagnosing auto-update activity uses `update-check.json`, never `install.json.updated_at` (which a manual update also bumps).
+
+**D5 — Unify channel vocabulary and `install.json` schema.**
+All writers emit `{ version: 1, installed_path, channel, binary_version, updated_at }`; `version` is the metadata schema version (distinct from `binary_version`). Defaults unified to `stable`; legacy `latest` coerces to `stable` on read.
+
+## Risks / Trade-offs
+
+- [Existing `install.json` with `channel: "latest"` from older npm installs] → `coerceChannel` maps unknown values to `stable`, so they transparently behave as stable; no migration needed.
+- [`stable` users who never auto-updated now will] → intended fix; bounded by the same env/config opt-outs (`CLICKZETTA_DISABLE_AUTOUPDATE`, `autoupdate: false`, `CZ_SKIP_UPDATE`) and the check interval.
+- [Installer is the channel authority, but a fresh install before first `cz-cli update` may lack `install.json`] → resolution defaults to `stable`; every installer now writes `install.json`, so this window is minimal.
+- [Drift between the five writers] → mitigated by tests: `setup.sh` install.json contract test, bootstrap channel-resolution and channel-not-gating tests; the COS bootstrap `CHANNEL="stable"` assertion already exists.
+
+## Migration Plan
+
+1. Land code/scripts together (single change); no data migration required.
+2. Existing `install.json` files are read-compatible (legacy `latest` → `stable`).
+3. Rollback: revert the change; auto-update returns to nightly-only behavior. No persisted-state cleanup needed (schema `version` unchanged).
+
+## Open Questions
+
+- Should `nightly` ever be surfaced to end users, or remain dev-only? Current decision: dev-only stream, `stable` is the default for all user-facing installs.

+## Why
+
+cz-cli's auto-update silently stopped working for `stable` users: the update logic was gated to only run on the `nightly` channel, and it reused opencode's build-time `InstallationChannel` constant — which is also wired into per-channel DB isolation, telemetry, and dev-mode detection. Channel naming was inconsistent (`latest` / `stable` / `nightly`) across install paths, and `scripts/install.sh` never wrote the `install.json` metadata at all, so the channel a user installed could not be reliably recovered. This made the behavior fragile and easy to break unknowingly (a single rename regressed it).
+
+## What Changes
+
+- Introduce a dedicated **release channel** concept for cz-cli, isolated from opencode's `InstallationChannel`. Values: `stable` (default) and `nightly`. Resolution order: `CZ_CHANNEL` env → `~/.clickzetta/install.json` `channel` → `stable`. Unknown/legacy values (e.g. `latest`) coerce to `stable`.
+- **BREAKING (behavioral)**: Auto-update is no longer gated by channel. It runs for any real install (valid semver version + supported install method), on both `stable` and `nightly`. Channel only selects the update stream (`stable` → `api/stable` + `install.sh`; `nightly` → `api/nightly` + `install-nightly.sh`). Dev/local builds remain excluded via the existing `semver.valid(version)` guard.
+- Stop deriving/writing the persisted channel from `InstallationChannel`; `writeInstallMetadata` now preserves the existing `install.json` channel (default `stable`).
+- All install/update entry points MUST create-or-update `~/.clickzetta/install.json` with the channel: `setup.sh`, `scripts/install.sh`, npm `postinstall.js`, `cz-cli update`, and auto-update. Defaults unified to `stable`.
+- Define the two-file state model as a contract: `install.json` (channel memory, written by every entry point) vs `update-check.json` (auto-update activity log, written only by the auto-update path).
+
+## Capabilities
+
+### New Capabilities
+- `release-channel`: The cz-cli release-channel concept — allowed values, resolution precedence, isolation from opencode's `InstallationChannel`, the `install.json` schema/contract, and the requirement that every install/update entry point persists the channel.
+- `auto-update`: When auto-update runs and is skipped, channel-as-stream-selector (not a gate), the two-file state model, and update vs notify behavior.
+
+### Modified Capabilities
+<!-- None: no previously archived specs exist for these capabilities. -->
+
+## Impact
+
+- Code: `packages/opencode/src/update/bootstrap.ts` (channel resolution, gating, metadata write), `packages/cz-cli/src/commands/update.ts` (channel resolution), `packages/npm/cz-cli/bin/postinstall.js`, `scripts/setup.sh`, `scripts/install.sh`.
+- Behavior: `stable` users now receive automatic updates. nightly continues to auto-update.
+- Not affected: opencode `InstallationChannel` and its consumers (per-channel DB path, OTel `deployment.environment.name`, `isLocal()`/`isPreview()`, plugin version pinning) are intentionally left unchanged.
+- Env/config: new `CZ_CHANNEL` override; existing `CLICKZETTA_DISABLE_AUTOUPDATE` / `CZ_SKIP_UPDATE` / `CLICKZETTA_AUTOUPDATE` / `autoupdate` config continue to apply.

+## ADDED Requirements
+
+### Requirement: Auto-update is not gated by channel
+
+Auto-update SHALL run for any real install regardless of release channel. Enablement SHALL be determined by: the update not being disabled (via config `autoupdate: false` or env `CLICKZETTA_DISABLE_AUTOUPDATE` / `CZ_SKIP_UPDATE` / one-shot `CLICKZETTA_SKIP_UPDATE_ONCE`), the command not being in the skip list (`setup`, `update`, `uninstall`, `--help`/`-h`, `--version`/`-v`), the installed version being valid semver, a supported install method, and the check interval having elapsed. The channel value SHALL NOT decide whether auto-update runs.
+
+#### Scenario: Stable install upgrades
+
+- **WHEN** a `stable` install has a supported method, a valid current version, an available newer version, and the interval has elapsed
+- **THEN** the resolved action is `upgrade`
+
+#### Scenario: Dev/local builds are skipped
+
+- **WHEN** the installed version is not valid semver (for example a `local` dev build)
+- **THEN** auto-update is skipped
+
+#### Scenario: Real install is not skipped on any channel
+
+- **WHEN** the command is a normal command, no skip env is set, and the version is valid semver
+- **THEN** auto-update is not skipped, independent of the channel
+
+### Requirement: Channel selects the update stream
+
+The release channel SHALL select the version source and install mechanism: `stable` uses `https://cz-cli.ai/api/stable` and `install.sh`; `nightly` uses `https://cz-cli.ai/api/nightly` and `install-nightly.sh`. Both `stable` and `nightly` are eligible for automatic upgrade.
+
+#### Scenario: Stable stream endpoints
+
+- **WHEN** the release channel is `stable`
+- **THEN** the latest version is fetched from the stable endpoint and upgrades use the stable install script
+
+#### Scenario: Nightly stream endpoints
+
+- **WHEN** the release channel is `nightly`
+- **THEN** the latest version is fetched from the nightly endpoint and upgrades use the nightly install script
+
+### Requirement: Two-file update state model
+
+The system SHALL maintain two distinct files. `~/.clickzetta/install.json` is channel/identity memory written by every install and update entry point. `~/.local/state/clickzetta/update-check.json` (XDG state) SHALL be written ONLY by the automatic update path and SHALL record `last_checked_at`, `last_result`, and `latest_version`. Determining whether an automatic update occurred SHALL rely on `update-check.json`, not on `install.json.updated_at`.
+
+#### Scenario: Manual update does not write the auto-update state file
+
+- **WHEN** the user runs `cz-cli update`
+- **THEN** `install.json` is updated but `update-check.json` is not written
+
+#### Scenario: Auto-update records its activity
+
+- **WHEN** the automatic update path performs a check
+- **THEN** `update-check.json` is written with `last_checked_at` and a `last_result`
+
+### Requirement: Notify versus upgrade
+
+When a newer version is available, the system SHALL perform an automatic in-place upgrade if the install method is one of the supported managed methods (`curl`, `npm`, `pnpm`, `yarn`, `bun`) and autoupdate is enabled; otherwise it SHALL notify the user that an update is available.
+
+#### Scenario: Unsupported method notifies
+
+- **WHEN** a newer version is available but the install method is unsupported
+- **THEN** the resolved action is `notify`
+
+#### Scenario: Notify-only configuration
+
+- **WHEN** `autoupdate` is configured to `notify`
+- **THEN** the user is informed of the available update and no automatic upgrade is performed

+## ADDED Requirements
+
+### Requirement: Release channel is isolated from opencode InstallationChannel
+
+cz-cli SHALL maintain a release channel concept that is separate from opencode's build-time `InstallationChannel` constant. The release channel MUST NOT be derived from `InstallationChannel`, and the update subsystem MUST NOT read `InstallationChannel` to determine the release stream. opencode's `InstallationChannel` and its consumers (per-channel DB path, telemetry `deployment.environment.name`, `isLocal()`/`isPreview()`, plugin version pinning) MUST remain unaffected.
+
+#### Scenario: Update subsystem does not reference InstallationChannel
+
+- **WHEN** the update/auto-update code resolves the release channel
+- **THEN** the value is computed from `CZ_CHANNEL`, `install.json`, or the default, and not from `InstallationChannel`
+
+#### Scenario: opencode channel consumers unchanged
+
+- **WHEN** the release channel changes between `stable` and `nightly`
+- **THEN** the SQLite DB path, telemetry environment, and dev-mode detection derived from `InstallationChannel` are unchanged
+
+### Requirement: Allowed channel values and default
+
+The release channel SHALL be one of `stable` or `nightly`. `stable` SHALL be the default for all user-facing installs. Unknown or legacy values (for example `latest`) SHALL coerce to `stable` when read.
+
+#### Scenario: Unknown value coerces to stable
+
+- **WHEN** `install.json` contains `"channel": "latest"`
+- **THEN** the resolved release channel is `stable`
+
+#### Scenario: Default when unset
+
+- **WHEN** no `CZ_CHANNEL` env is set and `install.json` has no usable channel
+- **THEN** the resolved release channel is `stable`
+
+### Requirement: Channel resolution precedence
+
+The release channel SHALL be resolved with the precedence: `CZ_CHANNEL` environment variable, then `~/.clickzetta/install.json` `channel`, then `stable`.
+
+#### Scenario: Env overrides install.json
+
+- **WHEN** `install.json` has `"channel": "nightly"` and `CZ_CHANNEL=stable` is set
+- **THEN** the resolved release channel is `stable`
+
+#### Scenario: install.json used when env unset
+
+- **WHEN** `CZ_CHANNEL` is unset and `install.json` has `"channel": "nightly"`
+- **THEN** the resolved release channel is `nightly`
+
+### Requirement: install.json schema and persistence contract
+
+Every install or update entry point — the bundled `setup.sh`, `scripts/install.sh`, the npm `postinstall.js`, the `cz-cli update` command, and the automatic update path — SHALL create or update `~/.clickzetta/install.json`. The file SHALL contain `version` (metadata schema version, currently `1`), `installed_path`, `channel`, `binary_version`, and `updated_at`. The `version` field is the metadata schema version and is distinct from `binary_version` (the cz-cli program version); changing the file structure SHALL bump `version`.
+
+#### Scenario: setup.sh persists the channel
+
+- **WHEN** `setup.sh` runs with `CZ_VERSION` set and no `CZ_CHANNEL`
+- **THEN** `install.json` is written with `channel` = `stable` and `binary_version` = the installed version
+
+#### Scenario: CZ_CHANNEL override persisted
+
+- **WHEN** `setup.sh` runs with `CZ_CHANNEL=nightly`
+- **THEN** `install.json` is written with `channel` = `nightly`
+
+#### Scenario: An updated channel is preserved across writes
+
+- **WHEN** `writeInstallMetadata` is called and `install.json` already has a `channel`
+- **THEN** the existing channel is retained unless an explicit channel is provided, and never replaced by `InstallationChannel`

+# auto-update Specification
+
+## Purpose
+Defines when cz-cli updates itself automatically, how the release channel selects the update stream (version source and install mechanism), the two-file update state model, and notify-versus-upgrade behavior.
+## Requirements

+
+Auto-update SHALL run for any real install regardless of release channel. Enablement SHALL be determined by: the update not being disabled (via config `autoupdate: false` or env `CLICKZETTA_DISABLE_AUTOUPDATE` / `CZ_SKIP_UPDATE` / one-shot `CLICKZETTA_SKIP_UPDATE_ONCE`), the command not being in the skip list (`setup`, `update`, `uninstall`, `--help`/`-h`, `--version`/`-v`), the installed version being valid semver, a supported install method, and the check interval having elapsed.

+
+#### Scenario: Stable install upgrades
+
+- **WHEN** a `stable` install has a supported method, a valid current version, an available newer version, and the interval has elapsed

+
+#### Scenario: Dev/local builds are skipped
+

+#### Scenario: Real install is not skipped on any channel
+
+- **WHEN** the command is a normal command, no skip env is set, and the version is valid semver
+- **THEN** auto-update is not skipped, independent of the channel
+
+### Requirement: Channel selects the update stream; method never selects the version
+
+The release channel SHALL be the sole source of the target version, always resolved from cz-cli.ai: `stable` from `https://cz-cli.ai/api/stable`, `nightly` from `https://cz-cli.ai/api/nightly`. The install method SHALL NOT influence version resolution — it only selects the upgrade mechanism (`stable` → `install.sh`; `nightly` → `install-nightly.sh`; managed package managers use their own install command). In particular, version resolution SHALL NOT query the npm registry's `latest` dist-tag, even when the install method is npm/pnpm/yarn/bun. Both `stable` and `nightly` are eligible for automatic upgrade.
+
+#### Scenario: Stable stream endpoints
+
+- **WHEN** the release channel is `stable`
+- **THEN** the latest version is fetched from `https://cz-cli.ai/api/stable` and upgrades use the stable install script
+
+#### Scenario: Nightly stream endpoints
+
+- **WHEN** the release channel is `nightly`
+- **THEN** the latest version is fetched from `https://cz-cli.ai/api/nightly` and upgrades use the nightly install script
+
+#### Scenario: npm install method does not change the version source
+
+- **WHEN** the install method is npm/pnpm/yarn/bun on the `stable` channel
+- **THEN** the target version is still fetched from `https://cz-cli.ai/api/stable` and the npm registry is not queried for version resolution
+
+#### Scenario: npm lacks the resolved version
+
+- **WHEN** the channel-resolved version is not yet published to the npm registry
+- **THEN** the package-manager upgrade may fail and the system falls back to the install script for that channel
+
+### Requirement: Two-file update state model
+
+The system SHALL maintain two distinct files. `~/.clickzetta/install.json` is channel/identity memory written by every install and update entry point. `~/.local/state/clickzetta/update-check.json` (XDG state) SHALL be written ONLY by the automatic update path and SHALL record `last_checked_at`, `last_result`, and `latest_version`. Determining whether an automatic update occurred SHALL rely on `update-check.json`, not on `install.json.updated_at`.
+
+#### Scenario: Manual update does not write the auto-update state file
+
+- **WHEN** the user runs `cz-cli update`
+- **THEN** `install.json` is updated but `update-check.json` is not written
+
+#### Scenario: Auto-update records its activity
+
+- **WHEN** the automatic update path performs a check
+- **THEN** `update-check.json` is written with `last_checked_at` and a `last_result`
+

+
+- **WHEN** a newer version is available but the install method is unsupported
+- **THEN** the resolved action is `notify`

+
+- **WHEN** `autoupdate` is configured to `notify`
+- **THEN** the user is informed of the available update and no automatic upgrade is performed

+- **WHEN** `setup.sh` runs with `CZ_VERSION` set and no `CZ_CHANNEL`
+- **THEN** `install.json` is written with `channel` = `stable` and `binary_version` = the installed version
+
+#### Scenario: CZ_CHANNEL override persisted
+
+- **WHEN** `setup.sh` runs with `CZ_CHANNEL=nightly`
+- **THEN** `install.json` is written with `channel` = `nightly`
+
+#### Scenario: An updated channel is preserved across writes
+
+- **WHEN** `writeInstallMetadata` is called and `install.json` already has a `channel`
+- **THEN** the existing channel is retained unless an explicit channel is provided, and never replaced by `InstallationChannel`

Subject: [PATCH 379/521] feat(job): add --limit/--no-limit and --path to `job
 profile --raw`

Replace the always-write-to-temp-file behavior of `cz-cli job profile --raw` with explicit control:

- --limit (default true): truncate raw output; --no-limit prints the full payload.
- --path <file>: write the full raw payload to a chosen file (no temp file otherwise).
- Surface limit_chars and a clearer AI message suggesting --no-limit.
- Update guide-builder options, e2e help expectations, prompt docs, and tests.

-# auto-update Specification
+# auto-update 规格说明
 
-## Purpose
-Defines when cz-cli updates itself automatically, how the release channel selects the update stream (version source and install mechanism), the two-file update state model, and notify-versus-upgrade behavior.
-## Requirements
-### Requirement: Auto-update is not gated by channel
+## 目的
+定义 cz-cli 何时自动更新自身、发布渠道如何选择更新流（版本来源和安装机制）、双文件更新状态模型，以及通知与升级行为。
 
-Auto-update SHALL run for any real install regardless of release channel. Enablement SHALL be determined by: the update not being disabled (via config `autoupdate: false` or env `CLICKZETTA_DISABLE_AUTOUPDATE` / `CZ_SKIP_UPDATE` / one-shot `CLICKZETTA_SKIP_UPDATE_ONCE`), the command not being in the skip list (`setup`, `update`, `uninstall`, `--help`/`-h`, `--version`/`-v`), the installed version being valid semver, a supported install method, and the check interval having elapsed. The channel value SHALL NOT decide whether auto-update runs.
+## 需求
+### 需求：自动更新不受渠道限制
 
-#### Scenario: Stable install upgrades
+自动更新应在任何真实安装上运行，不受发布渠道影响。启用条件由以下因素决定：更新未被禁用（通过配置 `autoupdate: false` 或环境变量 `CLICKZETTA_DISABLE_AUTOUPDATE` / `CZ_SKIP_UPDATE` / 一次性 `CLICKZETTA_SKIP_UPDATE_ONCE`），命令不在跳过列表中（`setup`、`update`、`uninstall`、`--help`/`-h`、`--version`/`-v`），已安装版本为有效 semver，安装方式受支持，且检查间隔已到期。渠道值不应决定自动更新是否运行。
 
-- **WHEN** a `stable` install has a supported method, a valid current version, an available newer version, and the interval has elapsed
-- **THEN** the resolved action is `upgrade`
+#### 场景：Stable 安装执行升级
 
-#### Scenario: Dev/local builds are skipped
+- **当** `stable` 安装具有受支持的方式、有效的当前版本、可用的更新版本且间隔已到期时
+- **则** 解析的操作为 `upgrade`
 
-- **WHEN** the installed version is not valid semver (for example a `local` dev build)
-- **THEN** auto-update is skipped
+#### 场景：Dev/本地构建被跳过
 
-#### Scenario: Real install is not skipped on any channel
+- **当** 已安装版本不是有效 semver（例如 `local` 开发构建）时
+- **则** 自动更新被跳过
 
-- **WHEN** the command is a normal command, no skip env is set, and the version is valid semver
-- **THEN** auto-update is not skipped, independent of the channel
+#### 场景：真实安装在任何渠道下都不被跳过
 
-### Requirement: Channel selects the update stream; method never selects the version
+- **当** 命令为正常命令、未设置跳过环境变量且版本为有效 semver 时
+- **则** 自动更新不被跳过，与渠道无关
 
-The release channel SHALL be the sole source of the target version, always resolved from cz-cli.ai: `stable` from `https://cz-cli.ai/api/stable`, `nightly` from `https://cz-cli.ai/api/nightly`. The install method SHALL NOT influence version resolution — it only selects the upgrade mechanism (`stable` → `install.sh`; `nightly` → `install-nightly.sh`; managed package managers use their own install command). In particular, version resolution SHALL NOT query the npm registry's `latest` dist-tag, even when the install method is npm/pnpm/yarn/bun. Both `stable` and `nightly` are eligible for automatic upgrade.
+### 需求：渠道选择更新流；安装方式不选择版本
 
-#### Scenario: Stable stream endpoints
+发布渠道应是目标版本的唯一来源，始终从 cz-cli.ai 解析：`stable` 来自 `https://cz-cli.ai/api/stable`，`nightly` 来自 `https://cz-cli.ai/api/nightly`。安装方式不应影响版本解析——它仅选择升级机制（`stable` → `install.sh`；`nightly` → `install-nightly.sh`；托管包管理器使用其自身的安装命令）。特别地，版本解析不应查询 npm 仓库的 `latest` dist-tag，即使安装方式为 npm/pnpm/yarn/bun。`stable` 和 `nightly` 均可自动升级。
 
-- **WHEN** the release channel is `stable`
-- **THEN** the latest version is fetched from `https://cz-cli.ai/api/stable` and upgrades use the stable install script
+#### 场景：Stable 流端点
 
-#### Scenario: Nightly stream endpoints
+- **当** 发布渠道为 `stable` 时
+- **则** 最新版本从 `https://cz-cli.ai/api/stable` 获取，升级使用 stable 安装脚本
 
-- **WHEN** the release channel is `nightly`
-- **THEN** the latest version is fetched from `https://cz-cli.ai/api/nightly` and upgrades use the nightly install script
+#### 场景：Nightly 流端点
 
-#### Scenario: npm install method does not change the version source
+- **当** 发布渠道为 `nightly` 时
+- **则** 最新版本从 `https://cz-cli.ai/api/nightly` 获取，升级使用 nightly 安装脚本
 
-- **WHEN** the install method is npm/pnpm/yarn/bun on the `stable` channel
-- **THEN** the target version is still fetched from `https://cz-cli.ai/api/stable` and the npm registry is not queried for version resolution
+#### 场景：npm 安装方式不改变版本来源
 
-#### Scenario: npm lacks the resolved version
+- **当** 安装方式为 npm/pnpm/yarn/bun 且渠道为 `stable` 时
+- **则** 目标版本仍从 `https://cz-cli.ai/api/stable` 获取，不查询 npm 仓库进行版本解析
 
-- **WHEN** the channel-resolved version is not yet published to the npm registry
-- **THEN** the package-manager upgrade may fail and the system falls back to the install script for that channel
+#### 场景：包管理器升级接收已解析的渠道
 
-### Requirement: Two-file update state model
+- **当** 安装方式为 npm/pnpm/yarn/bun 且已解析的发布渠道为 `nightly` 时
+- **则** 包管理器升级命令以 `CZ_CHANNEL=nightly` 执行
+- **且** npm `postinstall.js` 持久化 `channel` = `nightly`
 
-The system SHALL maintain two distinct files. `~/.clickzetta/install.json` is channel/identity memory written by every install and update entry point. `~/.local/state/clickzetta/update-check.json` (XDG state) SHALL be written ONLY by the automatic update path and SHALL record `last_checked_at`, `last_result`, and `latest_version`. Determining whether an automatic update occurred SHALL rely on `update-check.json`, not on `install.json.updated_at`.
+#### 场景：npm 缺少已解析的版本
 
-#### Scenario: Manual update does not write the auto-update state file
+- **当** 渠道解析的版本尚未发布到 npm 仓库时
+- **则** 包管理器升级可能失败，系统回退到该渠道的安装脚本
 
-- **WHEN** the user runs `cz-cli update`
-- **THEN** `install.json` is updated but `update-check.json` is not written
+### 需求：双文件更新状态模型
 
-#### Scenario: Auto-update records its activity
+系统应维护两个独立文件。`~/.clickzetta/install.json` 是渠道/身份记忆，由每次安装和更新入口写入。`~/.local/state/clickzetta/update-check.json`（XDG state）仅由自动更新路径写入，记录 `last_checked_at`、`last_result` 和 `latest_version`。判断自动更新是否发生应依赖 `update-check.json`，而非 `install.json.updated_at`。
 
-- **WHEN** the automatic update path performs a check
-- **THEN** `update-check.json` is written with `last_checked_at` and a `last_result`
+#### 场景：手动更新不写入自动更新状态文件
 
-### Requirement: Notify versus upgrade
+- **当** 用户运行 `cz-cli update` 时
+- **则** `install.json` 被更新但 `update-check.json` 不被写入
 
-When a newer version is available, the system SHALL perform an automatic in-place upgrade if the install method is one of the supported managed methods (`curl`, `npm`, `pnpm`, `yarn`, `bun`) and autoupdate is enabled; otherwise it SHALL notify the user that an update is available.
+#### 场景：自动更新记录其活动
 
-#### Scenario: Unsupported method notifies
+- **当** 自动更新路径执行检查时
+- **则** `update-check.json` 被写入，包含 `last_checked_at` 和 `last_result`
 
-- **WHEN** a newer version is available but the install method is unsupported
-- **THEN** the resolved action is `notify`
+### 需求：通知与升级
 
-#### Scenario: Notify-only configuration
+当有更新版本可用时，如果安装方式为受支持的托管方式之一（`curl`、`npm`、`pnpm`、`yarn`、`bun`）且自动更新已启用，系统应执行自动就地升级；否则应通知用户有更新可用。
 
-- **WHEN** `autoupdate` is configured to `notify`
-- **THEN** the user is informed of the available update and no automatic upgrade is performed
+#### 场景：不受支持的方式执行通知
 
+- **当** 有更新版本可用但安装方式不受支持时
+- **则** 解析的操作为 `notify`
+
+#### 场景：仅通知配置
+
+- **当** `autoupdate` 配置为 `notify` 时
+- **则** 通知用户有可用更新，不执行自动升级

-# release-channel Specification
+# release-channel 规格说明
 
-## Purpose
-Defines cz-cli's release channel (`stable`/`nightly`): its allowed values and default, resolution precedence, isolation from opencode's `InstallationChannel`, and the `install.json` schema that every install/update entry point must persist.
-## Requirements
-### Requirement: Release channel is isolated from opencode InstallationChannel
+## 目的
+定义 cz-cli 的发布渠道（`stable`/`nightly`）：其允许的值和默认值、解析优先级、与 opencode 的 `InstallationChannel` 的隔离，以及每个安装/更新入口必须持久化的 `install.json` schema。
 
-cz-cli SHALL maintain a release channel concept that is separate from opencode's build-time `InstallationChannel` constant. The release channel MUST NOT be derived from `InstallationChannel`, and the update subsystem MUST NOT read `InstallationChannel` to determine the release stream. opencode's `InstallationChannel` and its consumers (per-channel DB path, telemetry `deployment.environment.name`, `isLocal()`/`isPreview()`, plugin version pinning) MUST remain unaffected.
+## 需求
+### 需求：发布渠道与 opencode InstallationChannel 隔离
 
-#### Scenario: Update subsystem does not reference InstallationChannel
+cz-cli 应维护一个独立于 opencode 构建时 `InstallationChannel` 常量的发布渠道概念。发布渠道不得从 `InstallationChannel` 派生，更新子系统不得读取 `InstallationChannel` 来确定发布流。opencode 的 `InstallationChannel` 及其消费者（按渠道区分的数据库路径、遥测 `deployment.environment.name`、`isLocal()`/`isPreview()`、插件版本固定）必须不受影响。
 
-- **WHEN** the update/auto-update code resolves the release channel
-- **THEN** the value is computed from `CZ_CHANNEL`, `install.json`, or the default, and not from `InstallationChannel`
+#### 场景：更新子系统不引用 InstallationChannel
 
-#### Scenario: opencode channel consumers unchanged
+- **当** 更新/自动更新代码解析发布渠道时
+- **则** 值从 `CZ_CHANNEL`、`install.json` 或默认值计算得出，而非从 `InstallationChannel`
 
-- **WHEN** the release channel changes between `stable` and `nightly`
-- **THEN** the SQLite DB path, telemetry environment, and dev-mode detection derived from `InstallationChannel` are unchanged
+#### 场景：opencode 渠道消费者不变
 
-### Requirement: Allowed channel values and default
+- **当** 发布渠道在 `stable` 和 `nightly` 之间切换时
+- **则** 由 `InstallationChannel` 派生的 SQLite 数据库路径、遥测环境和开发模式检测保持不变
 
-The release channel SHALL be one of `stable` or `nightly`. `stable` SHALL be the default for all user-facing installs. Unknown or legacy values (for example `latest`) SHALL coerce to `stable` when read.
+### 需求：允许的渠道值和默认值
 
-#### Scenario: Unknown value coerces to stable
+发布渠道应为 `stable` 或 `nightly` 之一。`stable` 应为所有面向用户安装的默认值。未知或遗留值（例如 `latest`）在读取时应强制转换为 `stable`。
 
-- **WHEN** `install.json` contains `"channel": "latest"`
-- **THEN** the resolved release channel is `stable`
+#### 场景：未知值强制转换为 stable
 
-#### Scenario: Default when unset
+- **当** `install.json` 包含 `"channel": "latest"` 时
+- **则** 解析的发布渠道为 `stable`
 
-- **WHEN** no `CZ_CHANNEL` env is set and `install.json` has no usable channel
-- **THEN** the resolved release channel is `stable`
+#### 场景：未设置时的默认值
 
-### Requirement: Channel resolution precedence
+- **当** 未设置 `CZ_CHANNEL` 环境变量且 `install.json` 无可用渠道时
+- **则** 解析的发布渠道为 `stable`
 
-The release channel SHALL be resolved with the precedence: `CZ_CHANNEL` environment variable, then `~/.clickzetta/install.json` `channel`, then `stable`.
+### 需求：渠道解析优先级
 
-#### Scenario: Env overrides install.json
+发布渠道的解析优先级为：`CZ_CHANNEL` 环境变量，然后 `~/.clickzetta/install.json` 中的 `channel`，然后 `stable`。
 
-- **WHEN** `install.json` has `"channel": "nightly"` and `CZ_CHANNEL=stable` is set
-- **THEN** the resolved release channel is `stable`
+#### 场景：环境变量覆盖 install.json
 
-#### Scenario: install.json used when env unset
+- **当** `install.json` 有 `"channel": "nightly"` 且设置了 `CZ_CHANNEL=stable` 时
+- **则** 解析的发布渠道为 `stable`
 
-- **WHEN** `CZ_CHANNEL` is unset and `install.json` has `"channel": "nightly"`
-- **THEN** the resolved release channel is `nightly`
+#### 场景：环境变量未设置时使用 install.json
 
-### Requirement: install.json schema and persistence contract
+- **当** `CZ_CHANNEL` 未设置且 `install.json` 有 `"channel": "nightly"` 时
+- **则** 解析的发布渠道为 `nightly`
 
-Every install or update entry point — the bundled `setup.sh`, `scripts/install.sh`, the npm `postinstall.js`, the `cz-cli update` command, and the automatic update path — SHALL create or update `~/.clickzetta/install.json`. The file SHALL contain `version` (metadata schema version, currently `1`), `installed_path`, `channel`, `binary_version`, and `updated_at`. The `version` field is the metadata schema version and is distinct from `binary_version` (the cz-cli program version); changing the file structure SHALL bump `version`.
+### 需求：install.json schema 和持久化契约
 
-#### Scenario: setup.sh persists the channel
+每个安装或更新入口——打包的 `setup.sh`、`scripts/install.sh`、npm `postinstall.js`、`cz-cli update` 命令和自动更新路径——应创建或更新 `~/.clickzetta/install.json`。文件应包含 `version`（元数据 schema 版本，当前为 `1`）、`installed_path`、`channel`、`binary_version` 和 `updated_at`。`version` 字段为元数据 schema 版本，与 `binary_version`（cz-cli 程序版本）不同；更改文件结构应递增 `version`。
 
-- **WHEN** `setup.sh` runs with `CZ_VERSION` set and no `CZ_CHANNEL`
-- **THEN** `install.json` is written with `channel` = `stable` and `binary_version` = the installed version
+#### 场景：setup.sh 持久化渠道
 
-#### Scenario: CZ_CHANNEL override persisted
+- **当** `setup.sh` 在设置了 `CZ_VERSION` 且未设置 `CZ_CHANNEL` 的情况下运行时
+- **则** `install.json` 写入 `channel` = `stable` 和 `binary_version` = 已安装版本
 
-- **WHEN** `setup.sh` runs with `CZ_CHANNEL=nightly`
-- **THEN** `install.json` is written with `channel` = `nightly`
+#### 场景：CZ_CHANNEL 覆盖被持久化
 
-#### Scenario: An updated channel is preserved across writes
+- **当** `setup.sh` 以 `CZ_CHANNEL=nightly` 运行时
+- **则** `install.json` 写入 `channel` = `nightly`
 
-- **WHEN** `writeInstallMetadata` is called and `install.json` already has a `channel`
-- **THEN** the existing channel is retained unless an explicit channel is provided, and never replaced by `InstallationChannel`
+#### 场景：npm postinstall 持久化显式渠道
 
+- **当** npm `postinstall.js` 以 `CZ_CHANNEL=nightly` 运行时
+- **则** `install.json` 写入 `channel` = `nightly`
+
+#### 场景：scripts install 使用渠道进行版本解析
+
+- **当** `scripts/install.sh` 在未指定显式版本且 `CZ_CHANNEL=nightly` 的情况下运行时
+- **则** 已安装的 `binary_version` 从 `https://cz-cli.ai/api/nightly` 解析
+- **且** `install.json` 写入 `channel` = `nightly`
+
+#### 场景：更新的渠道在写入时被保留
+
+- **当** 调用 `writeInstallMetadata` 且 `install.json` 已有 `channel` 时
+- **则** 现有渠道被保留，除非提供了显式渠道，且永远不被 `InstallationChannel` 替换
+
+#### 场景：更新写入已解析的渠道
+
+- **当** `cz-cli update` 或自动更新路径在解析 `channel` = `nightly` 后完成升级时
+- **则** `install.json` 写入 `channel` = `nightly`

 baseUrl contains a path segment

new URL(path, base) discards base's path component when path starts with "/",
causing profiles on single-domain deployments (e.g. xhs) to hit the wrong endpoint.

Subject: [PATCH 383/521] fix: prioritize which path for install method
 detection and pre-remove shadowing binaries

- resolveUpdateInstallMethod now checks which cz-cli (binaries[0]) before process.execPath
- update command removes shadowing binary via proper uninstall before performUpgrade
- install.sh pre-removes any cz-cli that would shadow the new install
- check_version only compares versions for binaries in our managed install dir
- build.ts archive step runs in parallel via Promise.all
- job profile positional describes ClickZetta Job ID format
- Updated auto-update openspec with new requirements

Subject: [PATCH 384/521] fix: install.sh uses npm/bun uninstall for package
 manager binaries instead of raw rm

- Detects if shadowing binary is npm/bun installed via symlink target or path
- Uses npm uninstall -g / bun remove -g accordingly
- Falls back to rm only for plain file binaries
- Updated openspec scenario to match

+## Development Workflow: TDD + OpenSpec
+
+This project uses **spec-driven development** (OpenSpec) with TDD:
+
+1. **Before any change**, read `openspec/config.yaml` to understand the spec schema and project context.
+2. **Check existing specs** in `openspec/specs/` for relevant contracts.
+3. **Update or create specs first** — any behavior change must have its contract updated in `openspec/specs/<topic>/spec.md` before or alongside the implementation.
+4. **If no spec exists** for the area being changed, create a new one under `openspec/specs/<topic>/spec.md` following the existing format (需求 + 场景 with WHEN/THEN).
+5. **Write/update tests** that verify the spec scenarios.
+6. **Implement** the change to pass the tests and satisfy the spec.
+7. **Commit spec + code + tests together** — specs are not separate PRs.

Subject: [PATCH 387/521] fix: remove quarantine bit and re-sign binary after
 install on macOS

unzip propagates com.apple.quarantine from the downloaded archive to
extracted files, causing Gatekeeper to SIGKILL the ad-hoc signed binary
on first run. Apply xattr -dr + codesign --sign - in install.sh
(download and --binary paths) and npm postinstall to clear this after
every install.

 # Pre-install: detect and remove any cz-cli binary that would shadow our install

From 8c5b581535b3dd4ad50e97547bf806b4c84f6f46 Mon Sep 17 00:00:00 2001
From: "lin.zhang" <lin.zhang@clickzetta.com>
Date: Tue, 9 Jun 2026 21:30:19 +0800
Subject: [PATCH 388/521] fix: install/update path priority and parallel
 archive compression

- install.sh pre-removes all shadowing binaries via which -a (npm uninstall -g / bun remove -g / rm)
- install.sh INSTALL_DIR overridable via CZ_INSTALL_DIR env, defaults to ~/.local/bin
- check_version only compares versions for binaries in our managed install dir
- resolveUpdateInstallMethod prioritizes which cz-cli over process.execPath
- update command pre-removes shadowing binary before performUpgrade
- Post-upgrade fixup copies fresh binary to which path if version mismatch
- upgradeViaInstallScript passes CZ_INSTALL_DIR to install in correct location
- build.ts archive step parallelized via Promise.all
- job profile describes ClickZetta Job ID format
- Added .kiro/steering/dev-workflow.md for Kiro CLI
- Updated AGENTS.md with TDD + OpenSpec workflow
- Updated openspec/specs/auto-update/spec.md with new requirements

+## Development Workflow: TDD + OpenSpec
+
+This project uses **spec-driven development** (OpenSpec) with TDD. **This is mandatory — do not skip any step.**
+
+### Step-by-step (follow in order, no exceptions)
+
+1. **Read `openspec/config.yaml`** — it lists which spec covers which area of the codebase.
+2. **Identify the relevant spec** from the "Spec coverage" map in `openspec/config.yaml`:
+   - If the area you are changing is listed → read that spec file before writing any code.
+   - If the area is listed under "Areas NOT yet covered" → you MUST create a new spec first.
+   - If you are unsure → treat it as uncovered and create a spec.
+3. **Update or create the spec** (`openspec/specs/<topic>/spec.md`) to reflect the new or changed behavior. Use 中文, WHEN/THEN scenario format.
+4. **Write or update tests** that verify the new spec scenarios.
+5. **Implement** the code change to pass the tests and satisfy the spec.
+6. **Commit spec + tests + code together** in one commit. Never commit code without a corresponding spec update.
+
+### What counts as a "behavior change" requiring a spec update
+
+- Any change to install/update/postinstall logic
+- Any change to how binaries are placed, signed, or permissions are set
+- Any change to GitHub Actions build or release steps
+- Any change to version resolution, channel selection, or auto-update logic
+- Any new CLI command or flag
+
+### What does NOT require a spec update
+
+- Pure refactors with no observable behavior change
+- Typo fixes, comment updates, log message wording
+- Test-only changes that add coverage for existing spec scenarios
+
+## Style Guide
+
+### General Principles
+
+- Keep things in one function unless composable or reusable
+- Avoid `try`/`catch` where possible
+- Avoid using the `any` type
+- Use Bun APIs when possible, like `Bun.file()`
+- Rely on type inference when possible; avoid explicit type annotations or interfaces unless necessary for exports or clarity
+- Prefer functional array methods (flatMap, filter, map) over for loops; use type guards on filter to maintain type inference downstream
+- In `src/config`, follow the existing self-export pattern at the top of the file (for example `export * as ConfigAgent from "./agent"`) when adding a new config module.
+
+Reduce total variable count by inlining when a value is only used once.
+
+```ts
+// Good
+const journal = await Bun.file(path.join(dir, "journal.json")).json()
+
+// Bad
+const journalPath = path.join(dir, "journal.json")
+const journal = await Bun.file(journalPath).json()
+```
+
+### Destructuring
+
+Avoid unnecessary destructuring. Use dot notation to preserve context.
+
+```ts
+// Good
+obj.a
+obj.b
+
+// Bad
+const { a, b } = obj
+```
+
+### Variables
+
+Prefer `const` over `let`. Use ternaries or early returns instead of reassignment.
+
+```ts
+// Good
+const foo = condition ? 1 : 2
+
+// Bad
+let foo
+if (condition) foo = 1
+else foo = 2
+```
+
+### Control Flow
+
+Avoid `else` statements. Prefer early returns.
+
+```ts
+// Good
+function foo() {
+  if (condition) return 1
+  return 2
+}
+
+// Bad
+function foo() {
+  if (condition) return 1
+  else return 2
+}
+```
+
+### Schema Definitions (Drizzle)
+
+Use snake_case for field names so column names don't need to be redefined as strings.
+
+```ts
+// Good
+const table = sqliteTable("session", {
+  id: text().primaryKey(),
+  project_id: text().notNull(),
+  created_at: integer().notNull(),
+})
+
+// Bad
+const table = sqliteTable("session", {
+  id: text("id").primaryKey(),
+  projectID: text("project_id").notNull(),
+  createdAt: integer("created_at").notNull(),
+})
+```
+
+## Verification (mandatory — no exceptions)
+
+**Never claim a fix works without running it.** Presenting analysis as a conclusion is not acceptable.
+
+### After every code change
+
+1. **Run the relevant tests**: `cd packages/opencode && bun test <test-file>` (or the closest test covering the changed code).
+2. **Run typecheck**: `bun typecheck` from the affected package directory.
+3. **Smoke-test the binary path if the change touches install/update/CLI logic**:
+   - Build a local binary: `cd packages/opencode && bun run script/build.ts --single`
+   - Execute the affected command directly: e.g. `dist/cz-cli-darwin-arm64/bin/cz-cli --version`
+4. **For shell script changes** (`install.sh`, `setup.sh`): run `bash -n scripts/install.sh` (syntax check) and test the specific function in isolation with `bash -x`.
+5. **For macOS signing/quarantine changes**: verify with `codesign -dvv <binary>` and `xattr -l <binary>` after install.
+
+### Debugging failures
+
+- **Do not guess the root cause** from source reading alone. Run the code and capture actual output.
+- Use `bash -x script.sh` or add `set -x` to isolate shell script failures.
+- For TypeScript runtime errors, run with `--inspect` or add temporary `console.error` to capture the actual execution path.
+- For binary/Gatekeeper issues: `spctl -a -v <binary>` shows Gatekeeper verdict; `codesign -dvv <binary>` shows signing detail.
+- If a command fails, **show the actual error output** in your response before proposing a fix.
+
+### What "done" means
+
+A task is done when:
+- Tests pass (show the output)
+- Typecheck passes (show the output)
+- The actual behavior matches the spec scenario (show the command and its output)
+
+Saying "this should work" or "the logic looks correct" without running anything is not done.
+
+## Testing
+
+- Avoid mocks as much as possible
+- Test actual implementation, do not duplicate logic into tests
+- Tests cannot run from repo root (guard: `do-not-run-tests-from-root`); run from package dirs like `packages/opencode`.
+
+## Type Checking
+
+- Always run `bun typecheck` from package directories (e.g., `packages/opencode`), never `tsc` directly.

+# macos-gatekeeper 规格说明
+
+## 目的
+
+定义 cz-cli 在 macOS 上安装/更新后消除 Gatekeeper 阻断的行为契约，确保二进制在首次运行时不被 SIGKILL。
+
+## 背景
+
+CI 构建时对 macOS 二进制执行 ad-hoc 签名（`codesign --force --sign -`）并清除 quarantine bit（`xattr -dr com.apple.quarantine`）。但 `unzip` / npm 包提取时会将 zip 包本身携带的 `com.apple.quarantine` xattr 传播到解压出的文件，导致 Gatekeeper 在首次执行时 SIGKILL 进程。
+
+## 需求
+
+### 需求：install.sh 下载安装后清除 quarantine 并重新签名
+
+`scripts/install.sh` 的 `download_and_install` 函数在将二进制 mv 到 `$INSTALL_DIR` 后，必须在 macOS 上清除 quarantine bit 并重新执行 ad-hoc 签名。
+
+#### 场景：curl 安装后首次运行不被 kill
+
+- **WHEN** 用户通过 `curl | sh` 安装 cz-cli，且操作系统为 macOS
+- **THEN** 安装完成后 `xattr -dr com.apple.quarantine` 已在二进制上执行
+- **AND** `codesign --force --sign -` 已在二进制上执行
+- **AND** 执行 `cz-cli --version` 不被 Gatekeeper SIGKILL
+
+### 需求：install.sh --binary 路径同样清除 quarantine 并重新签名
+
+`install_from_binary` 函数同样需要在 macOS 上执行清除和重签操作，因为本地二进制文件可能携带从其他来源继承的 quarantine bit。
+
+#### 场景：本地二进制安装后可正常运行
+
+- **WHEN** 用户通过 `install.sh --binary /path/to/cz-cli` 安装，且操作系统为 macOS
+- **THEN** 安装后二进制不携带 quarantine bit
+- **AND** 二进制持有有效的 ad-hoc 签名
+
+### 需求：npm postinstall 清除 quarantine 并重新签名
+
+`packages/npm/cz-cli/bin/postinstall.js` 在 `ensureInstalledBinary` 完成后，必须在 macOS 上清除 quarantine bit 并重新执行 ad-hoc 签名。
+
+#### 场景：npm install 后首次运行不被 kill
+
+- **WHEN** 用户通过 `npm install -g @clickzetta/cz-cli` 安装，且操作系统为 macOS
+- **THEN** postinstall 执行后二进制不携带 quarantine bit
+- **AND** 二进制持有有效的 ad-hoc 签名
+
+### 需求：签名操作不得中断安装流程
+
+所有 `xattr` 和 `codesign` 调用必须是非致命的——失败时静默忽略，不影响安装的整体成功判断。
+
+#### 场景：codesign 不可用时安装仍成功
+
+- **WHEN** 系统未安装 Xcode Command Line Tools（`codesign` 不在 PATH）
+- **THEN** 安装流程继续，不抛出错误
+
+#### 场景：非 macOS 系统不执行签名操作
+
+- **WHEN** 操作系统为 Linux 或 Windows
+- **THEN** `xattr` 和 `codesign` 调用不执行

Subject: [PATCH 390/521] feat(opencode): multi-llm-entry, quota recovery UI,
 and OTel improvements

Multi-LLM entry (core):
- Use llm entry name as providerID instead of provider type, so multiple
  entries of the same provider (e.g. two clickzetta keys) no longer collide
- parseProfilesToml keys providers by entry.name; model-resolution and
  dialog-model updated accordingly
- provider.ts inherits model catalog from database via _providerType option
  when entry name does not match any built-in provider ID
- Extract CLICKZETTA_MODELS / CLICKZETTA_PROVIDER_ENTRY to provider/clickzetta.ts
- _providerType in provider options drives clickzetta-specific logic
  (traceparent injection, quota detection) instead of providerID string match
- /model dialog: currentKey uses current.providerID directly; hasLlmEntries
  shows dialog even without external provider connections

Quota recovery UI:
- Two-step question flow: select provider first, then get provider-specific
  questions (model suggestions, default base URL, skip model for clickzetta)
- clickzetta default base URL: https://cn-shanghai-alicloud-aimesh.api.clickzetta.com/gateway/v1
- Question.Info gains required and defaultValue fields; TUI enforces required
  on Confirm tab and auto-fills defaultValue on submit
- Entry name question added; name conflict loops back with re-name prompt
- After recovery: bus.publish(ProvidersChanged) refreshes sync llm_entries;
  bus.publish(TuiEvent.ModelSet) switches local.model to new entry
- configureCustomModel passes new entry back to recover callback so correct
  modelID is used for retry instead of old clickzetta model ID
- rotated.configured flag suppresses misleading "Key rotated" message

OTel improvements:
- Capture full raw HTTP request (url, method, redacted headers, body, base64)
  to current LLM span via recordRawProviderRequest
- LLM spans: add SpanKind.CLIENT, gen_ai.conversation.id, array finish_reasons
- Remove 32KB truncation limit on span attributes
- setCurrentLlmSpan / clearCurrentLlmSpan wrap each LLM step span

Subject: [PATCH 391/521] feat(agent): data_engineer as default mode, full tool
 access, stronger SQL doc rule
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- data_engineer now uses build-like permissions (full tool access) instead of
  plan-like (edit-restricted); description updated accordingly
- data_engineer is the new default agent when no default_agent is configured
- Remove data_engineer from PLAN_LIKE_AGENTS in prompt.ts so it no longer
  triggers plan mode behavior
- Expand cz-cli-inner.txt SQL doc rule: now covers information_schema queries,
  SHOW/DESCRIBE statements, and any Lakehouse SQL — not just write operations;
  structured as a dedicated section for clarity

 ## Companion Skills
 
 When the task involves writing Python or Shell task code, load **lakehouse-python-sdk** for accuracy on connector usage, BulkLoad, IGS, and Python/Shell task development patterns.
-lakehouse-doc-en: When the user asks for lakehouse SQL dialect, documentation on connectors, BulkLoad, IGS, studio product information, or any task that requires generating, modifying, validating, or explaining Lakehouse SQL, use **lakehouse-doc-en** to provide accurate and detailed information.
+
+## Lakehouse SQL: Always Read the Docs First
+
+Before generating, modifying, validating, explaining, or running any Lakehouse SQL — including:
+- Writing new SQL queries or DDL/DML statements
+- Querying system tables or metadata (e.g. `information_schema.*`, `SHOW ...`, `DESCRIBE ...`)
+- Any task that touches ClickZetta Lakehouse SQL syntax
+
+You MUST first load **lakehouse-doc-en** to verify the correct ClickZetta Lakehouse dialect. This is NOT Snowflake or Databricks syntax. Guessing syntax without consulting the docs will produce incorrect SQL.
+
+This rule applies even for seemingly simple queries like `SELECT * FROM information_schema.tables` — the schema names, column names, and supported predicates differ from standard SQL and other platforms.

Subject: [PATCH 396/521] fix(setup): add codesign and quarantine clearing for
 macOS

- Add xattr -dr com.apple.quarantine and codesign --force --sign - to
  scripts/setup.sh so the bootstrap install path (cz-cli.ai/install.sh)
  no longer produces binaries killed by Gatekeeper
- Add codesign -v --verbose=4 verification step
- Remove unused 'Upload install script' step from release-cos workflow
- Rename scripts/install.sh to scripts/install.sh.bak (no longer used)

Subject: [PATCH 398/521] fix: avoid spurious "Model not valid" toast after
 quota key rotation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Republish ProvidersChanged after recoverRotation so the TUI refetches
the provider catalog and learns the freshly rotated [llm.<entry>], and
guard the server-requested-model effect to wait until the entry is known
instead of flashing a transient "Model … is not valid" warning.

Subject: [PATCH 399/521] fix(install): register cz-cli skill into external
 agent dirs across all install paths

Restore external-agent skill registration that was dropped when skill install was unified to builtin-only. npm postinstall, install.sh, and setup.sh now delete-then-install the bundled cz-cli skill into ~/.claude, ~/.kiro, ~/.cursor, ~/.codex, ~/.openclaw, ~/.singclaw skills dirs so Claude Code / Kiro / Codex / Cursor can call cz-cli. cz-cli update inherits this via install.sh and postinstall. Builtin .builtin install is unchanged.

Also restore scripts/install.sh (it had been renamed to install.sh.bak, which broke release/install tests), and make install_from_binary carry skills adjacent to the source binary.

+# skill-install 规格说明
+
+## 目的
+定义 cz-cli 在安装/更新时如何分发其捆绑的 skill：
+
+1. **内置 skill**（builtin）——供 cz-cli 自身的 agent 内核发现使用，安装到 `~/.clickzetta/skills/.builtin/`。
+2. **外部 agent skill**（external-agent registration）——将名为 `cz-cli` 的 skill 注册给其它 AI 编码助手（Claude Code、Kiro、Codex、Cursor 等），安装到这些 agent 的 skill 目录下，使它们可以直接调用 cz-cli 操作 Lakehouse。
+
+本规格覆盖三条安装入口：npm `postinstall.js`、`scripts/install.sh`（curl 安装）、`scripts/setup.sh`（手动/归档安装）。`cz-cli update` 不直接分发 skill，而是通过重新运行 install.sh 或包管理器（触发 `postinstall.js`）继承上述行为。
+
+## 术语
+- **捆绑 skill 源目录**：安装介质中包含各 skill 子目录（每个子目录含 `SKILL.md`）的 `skills/` 目录。`build.ts` 会把仓库 `skills/*`（含 `skills/cz-cli`）打包进每个平台产物的 `bin/skills/`。
+- **外部 agent skill 目录**：
+  - `~/.claude/skills`
+  - `~/.kiro/skills`
+  - `~/.cursor/skills`
+  - `~/.codex/skills`
+  - `~/.openclaw/workspace/skills`
+  - `~/.singclaw/workspace/skills`
+- **外部注册 skill 名单**：当前为 `cz-cli`（即 `skills/cz-cli`）。
+
+## 需求
+
+### 需求：内置 skill 安装到 .builtin（行为保持不变）
+
+所有安装入口应在每次安装/更新时，先整体清空 `~/.clickzetta/skills/.builtin/`，再用全部捆绑 skill 重新填充。此行为不受外部 agent 注册逻辑影响而改变。
+
+#### 场景：清空后重新填充内置 skill
+
+- **WHEN** 安装介质中存在捆绑 skill 源目录，且 `~/.clickzetta/skills/.builtin/` 中存在上一次安装遗留的 skill 时
+- **THEN** `.builtin/` 被整体清空，仅包含本次捆绑的全部 skill（遗留 skill 不再保留）
+
+#### 场景：无捆绑 skill 时仍清空内置目录
+
+- **WHEN** 安装介质中不存在任何捆绑 skill 时
+- **THEN** `~/.clickzetta/skills/.builtin/` 仍存在且被清空，不残留旧 skill
+
+### 需求：将 cz-cli skill 注册到外部 agent 目录（先删除再安装）
+
+当捆绑 skill 中存在外部注册名单中的 skill（当前为 `cz-cli`）时，每个安装入口应将该 skill 安装到全部外部 agent skill 目录。安装采用「先删除再安装」语义：对每个目标目录，先确保目录存在，再删除该目录下同名 skill 子目录，最后整体复制捆绑源中的该 skill。该操作必须是幂等的，且单个目录失败不应中断其余目录或整个安装流程。
+
+#### 场景：注册到所有外部 agent 目录
+
+- **WHEN** 捆绑 skill 中包含 `cz-cli` 且执行任一安装入口时
+- **THEN** `~/.claude/skills/cz-cli`、`~/.kiro/skills/cz-cli`、`~/.cursor/skills/cz-cli`、`~/.codex/skills/cz-cli`、`~/.openclaw/workspace/skills/cz-cli`、`~/.singclaw/workspace/skills/cz-cli` 均存在且内容来自捆绑源（包含 `SKILL.md`）
+
+#### 场景：先删除再安装覆盖旧内容
+
+- **WHEN** 某外部 agent 目录下已存在旧版本 `cz-cli` skill（例如残留的过期 `SKILL.md` 或多余文件）时
+- **THEN** 该目录下的旧 `cz-cli` 被整体删除后再写入新内容，不残留旧文件
+
+#### 场景：目标父目录不存在时自动创建
+
+- **WHEN** 用户尚未安装某个 agent（对应 skill 目录不存在）时
+- **THEN** 安装入口创建该 skill 目录并写入 `cz-cli` skill，不因目录缺失而报错
+
+#### 场景：捆绑源缺少 cz-cli 时不进行外部注册
+
+- **WHEN** 捆绑 skill 源目录中不存在 `cz-cli` 时
+- **THEN** 不向任何外部 agent 目录写入 `cz-cli`，且安装流程正常完成
+
+#### 场景：单个目录失败不影响整体
+
+- **WHEN** 写入某个外部 agent 目录因权限等原因失败时
+- **THEN** 其余外部 agent 目录的安装继续进行，且整个安装/更新流程不被中断（npm postinstall 不致使 `npm install` 失败）
+
+### 需求：清理废弃的旧 skill 名称
+
+历史版本曾以 `czagent`、`czcli`、`cz-cli-v2` 等名称注册 skill。安装入口应从所有外部 agent 目录中删除这些废弃名称的 skill，但不重新安装它们（它们已被统一为 `cz-cli`）。
+
+#### 场景：删除废弃别名
+
+- **WHEN** 外部 agent 目录中存在 `czagent` / `czcli` / `cz-cli-v2` 等废弃名称的 skill 时
+- **THEN** 这些废弃 skill 被删除，且不会被重新创建
+
+### 需求：update 命令继承安装入口的 skill 分发行为
+
+`cz-cli update` 不应自行实现 skill 分发逻辑。它通过重新运行 install.sh（curl 安装方式）或包管理器升级命令（npm/bun/pnpm/yarn 安装方式，触发 `postinstall.js`）来完成升级，从而自动继承内置 skill 与外部 agent skill 的安装行为。
+
+#### 场景：curl 安装方式的更新
+
+- **WHEN** 安装方式为 `curl` 且执行 `cz-cli update` 时
+- **THEN** 重新运行的 install.sh 同时完成 `.builtin` 内置 skill 安装与 `cz-cli` 外部 agent 注册
+
+#### 场景：包管理器安装方式的更新
+
+- **WHEN** 安装方式为 npm/bun/pnpm/yarn 且执行 `cz-cli update` 时
+- **THEN** 包管理器重新安装触发 `postinstall.js`，完成 `.builtin` 内置 skill 安装与 `cz-cli` 外部 agent 注册

+# cli-command-routing 规格说明
+
+## Purpose
+定义 cz-cli 顶层命令如何在 ClickZetta 数据命令、本地管理命令和 opencode agent 运行时之间路由，确保公开命令面与实际二进制行为一致。
+
+## Requirements
+
+### Requirement: 顶层 serve 命令透出 opencode agent server
+
+`cz-cli serve` MUST 作为顶层命令透出 opencode 的 headless agent server 能力，并保留 opencode serve 命令的参数语义。该命令属于 agent 运行时命令，MUST 由真实 cz-cli 二进制执行，不应通过 `execute()` 的进程内 API 执行。
+
+#### Scenario: 查看 serve 帮助
+
+- **WHEN** 用户执行 `cz-cli serve --help`
+- **THEN** 命令展示 serve 的帮助信息
+- **且** 帮助信息包含 headless agent server 的说明
+- **且** 不要求 ClickZetta profile 或 active LLM
+
+#### Scenario: programmatic execute 拒绝 serve
+
+- **WHEN** 调用方通过 `execute("serve --help")` 或 `execute("serve")` 运行 serve 命令时
+- **THEN** 返回 `UNSUPPORTED_PROGRAMMATIC_AGENT_RUNTIME`
+- **且** 提示调用方使用真实 cz-cli 二进制

-- To regenerate the JavaScript SDK, run `./packages/sdk/js/script/build.ts`.

-
-## Development Workflow: TDD + OpenSpec
-
-This project uses **spec-driven development** (OpenSpec) with TDD. **This is mandatory — do not skip any step.**
-
-### Step-by-step (follow in order, no exceptions)
-
-1. **Read `openspec/config.yaml`** — it lists which spec covers which area of the codebase.
-2. **Identify the relevant spec** from the "Spec coverage" map in `openspec/config.yaml`:
-   - If the area you are changing is listed → read that spec file before writing any code.
-   - If the area is listed under "Areas NOT yet covered" → you MUST create a new spec first.
-   - If you are unsure → treat it as uncovered and create a spec.
-3. **Update or create the spec** (`openspec/specs/<topic>/spec.md`) to reflect the new or changed behavior. Use 中文, WHEN/THEN scenario format.
-4. **Write or update tests** that verify the new spec scenarios.
-5. **Implement** the code change to pass the tests and satisfy the spec.
-6. **Commit spec + tests + code together** in one commit. Never commit code without a corresponding spec update.
-
-### What counts as a "behavior change" requiring a spec update
-
-- Any change to install/update/postinstall logic
-- Any change to how binaries are placed, signed, or permissions are set
-- Any change to GitHub Actions build or release steps
-- Any change to version resolution, channel selection, or auto-update logic
-- Any new CLI command or flag
-
-### What does NOT require a spec update
-
-- Pure refactors with no observable behavior change
-- Typo fixes, comment updates, log message wording
-- Test-only changes that add coverage for existing spec scenarios
-
-## Style Guide
-
-### General Principles
-
-- Keep things in one function unless composable or reusable
-- Avoid `try`/`catch` where possible
-- Avoid using the `any` type
-- Use Bun APIs when possible, like `Bun.file()`
-- Rely on type inference when possible; avoid explicit type annotations or interfaces unless necessary for exports or clarity
-- Prefer functional array methods (flatMap, filter, map) over for loops; use type guards on filter to maintain type inference downstream
-- In `src/config`, follow the existing self-export pattern at the top of the file (for example `export * as ConfigAgent from "./agent"`) when adding a new config module.
-
-Reduce total variable count by inlining when a value is only used once.
-
-```ts
-// Good
-const journal = await Bun.file(path.join(dir, "journal.json")).json()
-
-// Bad
-const journalPath = path.join(dir, "journal.json")
-const journal = await Bun.file(journalPath).json()
-```
-
-### Destructuring
-
-Avoid unnecessary destructuring. Use dot notation to preserve context.
-
-```ts
-// Good
-obj.a
-obj.b
-
-// Bad
-const { a, b } = obj
-```
-
-### Variables
-
-Prefer `const` over `let`. Use ternaries or early returns instead of reassignment.
-
-```ts
-// Good
-const foo = condition ? 1 : 2
-
-// Bad
-let foo
-if (condition) foo = 1
-else foo = 2
-```
-
-### Control Flow
-
-Avoid `else` statements. Prefer early returns.
-
-```ts
-// Good
-function foo() {
-  if (condition) return 1
-  return 2
-}
-
-// Bad
-function foo() {
-  if (condition) return 1
-  else return 2
-}
-```
-
-### Schema Definitions (Drizzle)
-
-Use snake_case for field names so column names don't need to be redefined as strings.
-
-```ts
-// Good
-const table = sqliteTable("session", {
-  id: text().primaryKey(),
-  project_id: text().notNull(),
-  created_at: integer().notNull(),
-})
-
-// Bad
-const table = sqliteTable("session", {
-  id: text("id").primaryKey(),
-  projectID: text("project_id").notNull(),
-  createdAt: integer("created_at").notNull(),
-})
-```
-
-## Verification (mandatory — no exceptions)
-
-**Never claim a fix works without running it.** Presenting analysis as a conclusion is not acceptable.
-
-### After every code change
-
-1. **Run the relevant tests**: `cd packages/opencode && bun test <test-file>` (or the closest test covering the changed code).
-2. **Run typecheck**: `bun typecheck` from the affected package directory.
-3. **Smoke-test the binary path if the change touches install/update/CLI logic**:
-   - Build a local binary: `cd packages/opencode && bun run script/build.ts --single`
-   - Execute the affected command directly: e.g. `dist/cz-cli-darwin-arm64/bin/cz-cli --version`
-4. **For shell script changes** (`install.sh`, `setup.sh`): run `bash -n scripts/install.sh` (syntax check) and test the specific function in isolation with `bash -x`.
-5. **For macOS signing/quarantine changes**: verify with `codesign -dvv <binary>` and `xattr -l <binary>` after install.
-
-### Debugging failures
-
-- **Do not guess the root cause** from source reading alone. Run the code and capture actual output.
-- Use `bash -x script.sh` or add `set -x` to isolate shell script failures.
-- For TypeScript runtime errors, run with `--inspect` or add temporary `console.error` to capture the actual execution path.
-- For binary/Gatekeeper issues: `spctl -a -v <binary>` shows Gatekeeper verdict; `codesign -dvv <binary>` shows signing detail.
-- If a command fails, **show the actual error output** in your response before proposing a fix.
-
-### What "done" means
-
-A task is done when:
-- Tests pass (show the output)
-- Typecheck passes (show the output)
-- The actual behavior matches the spec scenario (show the command and its output)
-
-Saying "this should work" or "the logic looks correct" without running anything is not done.
-
-## Testing
-
-- Avoid mocks as much as possible
-- Test actual implementation, do not duplicate logic into tests
-- Tests cannot run from repo root (guard: `do-not-run-tests-from-root`); run from package dirs like `packages/opencode`.
-
-## Type Checking
-
-- Always run `bun typecheck` from package directories (e.g., `packages/opencode`), never `tsc` directly.

Subject: [PATCH 402/521] fix(llm): map all providers to correct @ai-sdk npm
 package

customProviderFromEntry only handled "openai-compatible", leaving
"anthropic", "openai", "google", etc. with npm=undefined. This caused
the fallback to @ai-sdk/openai-compatible for all non-clickzetta custom
providers, sending /v1/chat/completions instead of the protocol-correct
endpoint (e.g. /v1/messages for Anthropic).

+## Context
+
+当前 `install.ps1` 由 `scripts/cos-release.mjs` 的 `renderBootstrapPs1` 生成。脚本默认安装到 `$HOME\.local\bin`，复制 `cz-cli.exe` 和 `cz-agent.cmd`，写入 `~\.clickzetta\install.json`，但当安装目录不在 PATH 中时只输出提示。Windows 11 用户常见默认 shell 仍是 Windows PowerShell 5.1，甚至旧环境可能缺少 `irm` alias；当前脚本使用 `??` 等 PowerShell 7 语法，因此不能作为兼容安装入口。
+
+## Goals / Non-Goals
+
+**Goals:**
+
+- 生成的 Windows `install.ps1` 必须可被 Windows PowerShell 5.1 解析。
+- 安装成功后，默认安装目录或 `INSTALL_DIR` 指定目录必须进入 User PATH，并立即追加到当前进程 `$env:Path`。
+- 安装输出必须给出不依赖 `irm` 的兼容命令，帮助旧 PowerShell 用户复制执行。
+- 保留现有版本比较、下载、校验、安装元数据和 `cz-agent.cmd` wrapper 行为。
+
+**Non-Goals:**
+
+- 不支持 Windows PowerShell 2.x 直接执行完整安装脚本；脚本目标基线是 Windows PowerShell 5.1。
+- 不改变 Windows binary 签名策略。
+- 不改变 macOS/Linux `install.sh` 行为。
+
+## Decisions
+
+1. **以 PowerShell 5.1 作为脚本语法基线。**  
+   Windows 11 默认包含 Windows PowerShell 5.1；PowerShell 7 不是系统默认组件。将 `??` 改为显式数组长度检查，避免解析期失败。替代方案是要求用户安装 PowerShell 7，但这会让默认 Windows 安装路径不够自助。
+
+2. **写入 User PATH，而不是 Machine PATH。**  
+   安装目录位于用户 home 下，写入 User PATH 不需要管理员权限，也与当前安装作用域一致。Machine PATH 需要提权，且会把单用户目录暴露给所有用户。
+
+3. **同时更新当前进程 PATH。**  
+   `[Environment]::SetEnvironmentVariable(..., "User")` 只影响后续进程。为了让安装命令结束后同一个 PowerShell 窗口可直接运行 `cz-cli`，脚本还要追加 `$env:Path`。
+
+4. **PATH 判断做大小写无关和末尾分隔符归一。**  
+   Windows 路径大小写不敏感，用户 PATH 中可能包含尾随 `\`。脚本需要避免重复追加同一目录。
+
+## Risks / Trade-offs
+
+- **PATH 写入失败** -> 安装不能因为 PATH 注册失败而丢失已下载 binary；脚本应输出明确 warning 和手动命令。
+- **企业策略限制环境变量写入** -> 同上，保留安装成功结果与手动修复提示。
+- **User PATH 已接近 Windows 长度限制** -> 使用追加策略；若系统拒绝写入，提示用户手动处理。

+## Why
+
+Windows 用户通过 `irm https://cz-cli.ai/install.ps1 | iex` 安装时，旧版 Windows PowerShell 缺少 `irm` alias，当前 `install.ps1` 又包含 PowerShell 7 专用语法，导致默认系统 shell 难以完成安装。即使安装成功，脚本只提示手动添加 `%USERPROFILE%\.local\bin` 到 PATH，用户在新 shell 中仍无法直接运行 `cz-cli`。
+
+## What Changes
+
+- 将 Windows `install.ps1` 生成为 Windows PowerShell 5.1 可解析的脚本，避免使用 PowerShell 7 专用语法。
+- 为 Windows 安装说明提供兼容老 PowerShell 的下载执行命令，不依赖 `irm` alias。
+- 安装成功后自动把安装目录写入 User PATH，并同步当前 PowerShell 进程的 `$env:Path`。
+- 保持 `INSTALL_DIR` 覆盖、版本检查、校验和验证、`install.json` 写入和 `cz-agent.cmd` wrapper 行为不变。
+
+## Capabilities
+
+### New Capabilities
+
+无。
+
+### Modified Capabilities
+
+- `auto-update`: Windows PowerShell 安装入口的 shell 兼容性与 PATH 注册行为。
+
+## Impact
+
+- `scripts/cos-release.mjs` 的 `renderBootstrapPs1` 输出。
+- `openspec/specs/auto-update/spec.md` 的安装脚本行为要求。
+- 覆盖 COS release 生成逻辑的测试。

+## ADDED Requirements
+
+### Requirement: Windows PowerShell 安装入口兼容默认系统 shell
+
+Windows `install.ps1` 安装入口 MUST 使用 Windows PowerShell 5.1 可解析的语法，并 MUST 提供不依赖 `irm` alias 的兼容下载执行命令。
+
+#### Scenario: Windows PowerShell 5.1 可解析安装脚本
+
+- **WHEN** 用户在 Windows PowerShell 5.1 中下载并执行 `install.ps1`
+- **THEN** 脚本解析阶段不因 PowerShell 7 专用语法失败
+
+#### Scenario: 旧 PowerShell 无 irm alias 时仍有安装命令
+
+- **WHEN** 用户环境中不存在 `irm` alias
+- **THEN** 安装说明提供基于 `Net.WebClient.DownloadString` 的命令执行 `install.ps1`
+
+### Requirement: Windows 安装成功后注册 User PATH
+
+Windows `install.ps1` 安装成功后 MUST 将安装目录注册到当前用户 PATH，并 MUST 同步当前 PowerShell 进程的 `$env:Path`。如果 PATH 注册失败，脚本 MUST 保留已安装 binary 并输出手动修复提示。
+
+#### Scenario: 默认安装目录写入 User PATH
+
+- **WHEN** `install.ps1` 将 `cz-cli.exe` 安装到默认目录 `$HOME\.local\bin` 且该目录不在 User PATH 中
+- **THEN** 脚本将该目录追加到 User PATH
+- **AND** 当前 PowerShell 进程可通过 `cz-cli` 解析到安装目录中的 binary
+
+#### Scenario: INSTALL_DIR 覆盖目录写入 User PATH
+
+- **WHEN** `INSTALL_DIR` 环境变量指定自定义安装目录且该目录不在 User PATH 中
+- **THEN** 脚本将该自定义目录追加到 User PATH
+
+#### Scenario: PATH 已包含安装目录时不重复追加
+
+- **WHEN** User PATH 已包含大小写不同或带尾随分隔符的安装目录
+- **THEN** 脚本不重复追加该目录

+## 1. Specification
+
+- [x] 1.1 Update `openspec/specs/auto-update/spec.md` with Windows PowerShell installer compatibility and PATH registration requirements.
+
+## 2. Tests
+
+- [x] 2.1 Add failing tests in `packages/opencode/test/cos-release-logging.test.ts` that assert generated `install.ps1` avoids PowerShell 7-only syntax and includes legacy-safe download guidance.
+- [x] 2.2 Add failing tests in `packages/opencode/test/cos-release-logging.test.ts` that assert generated `install.ps1` writes the install directory to User PATH, updates current `$env:Path`, and avoids duplicate PATH entries.
+
+## 3. Implementation
+
+- [x] 3.1 Update `scripts/cos-release.mjs` `renderBootstrapPs1` to emit PowerShell 5.1-safe version parsing code.
+- [x] 3.2 Update `scripts/cos-release.mjs` `renderBootstrapPs1` to register the install directory in User PATH and current process PATH with duplicate detection.
+- [x] 3.3 Update `scripts/cos-release.mjs` output messages to include a Windows PowerShell-compatible install command that does not rely on `irm`.
+
+## 4. Verification
+
+- [x] 4.1 Run the targeted Bun test file from `packages/opencode`.
+- [x] 4.2 Run `bun typecheck` from `packages/opencode`.
+- [x] 4.3 Run OpenSpec status/validation for `windows-powershell-installer-compat`.

+## Purpose
+定义 `cz-cli setup` 的交互式引导行为，确保用户可以通过账号站点获取 credential 并完成本地 profile 配置。
+
+## Requirements
+
+### Requirement: 交互式账号站点打开为 best-effort
+
+`cz-cli setup` 在交互式流程中展示登录或注册链接后 MAY 尝试打开系统浏览器，但浏览器打开失败 MUST NOT 中断 setup 流程。命令 MUST 始终把 URL 显示给用户，并继续等待用户粘贴 credential。
+
+#### Scenario: Windows 使用 shell 内建 start 打开浏览器
+
+- **WHEN** `cz-cli setup` 在 Windows 交互式流程中打开登录或注册链接
+- **THEN** 命令通过 `cmd.exe /c start "" <url>` 调用系统浏览器
+- **且** 不直接 spawn `start`
+
+#### Scenario: 浏览器打开失败后继续等待 credential
+
+- **WHEN** 系统浏览器打开命令不存在或启动失败
+- **THEN** `cz-cli setup` 不应抛出未处理异常
+- **且** 用户仍然可以根据终端中显示的 URL 手动打开页面并粘贴 credential

 ### 需求：将 cz-cli skill 注册到外部 agent 目录（先删除再安装）
 
 当捆绑 skill 中存在外部注册名单中的 skill（当前为 `cz-cli`）时，每个安装入口应将该 skill 安装到全部外部 agent skill 目录。安装采用「先删除再安装」语义：对每个目标目录，先确保目录存在，再删除该目录下同名 skill 子目录，最后整体复制捆绑源中的该 skill。该操作必须是幂等的，且单个目录失败不应中断其余目录或整个安装流程。

 ### 需求：安装方式检测优先使用 which 路径
 
 安装方式检测（`resolveUpdateInstallMethod`）应以 `which cz-cli` 解析的路径为首要判断依据，而非 `process.execPath`。这确保升级命令作用于用户实际执行的 binary 位置。仅当 `which` 结果无法识别时，才 fallback 到 `process.execPath`。

Subject: [PATCH 409/521] feat: add task stats command with run instance
 breakdown

New command: cz-cli task stats
- Reports task total, folder count, and run instance statistics
- Parallel fetch: listTasks + listFolders + getInstanceStats + getTaskRunStats
- run_instances: total, by_status (SUCCESS/FAILED/RUNNING/WAITING),
  by_run_type (SCHEDULE/TEMP/REFILL), by_task_type (PYTHON/SQL/etc.)
- task_run_breakdown: per task-type count with publish status

Filters:
  --folder <name|id>   Filter tasks and instances by folder
  --type <SQL|PYTHON>  Filter tasks and run instances by type
  --task <name>        Filter run instances by task name (fuzzy)
  --from / --to        Time range for run instances (default: last 7 days)
  --vc <code>          Filter run instances by VCluster

Subject: [PATCH 410/521] feat: add task search command with resolved folder
 path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New command: cz-cli task search

Features:
- Fuzzy name search across all pages (auto-paginates up to --limit)
- Resolves location "0.id1.id2.taskId" to human-readable path
  e.g. "Venture_Migration/05_Migration_Ready/Sgamk"
- task_edit_state displayed as draft/published/offline strings

Filters:
  --name <str>                 Task name fuzzy match
  --type <SQL|PYTHON|...>      Task type filter
  --status <draft|published|offline>  Filter by publish state
  --limit <n>                  Max results (default 50)

Path resolution: BFS across all folder levels via listFolders,
builds id→name map then resolves each task's location field.

Subject: [PATCH 411/521] feat: task search enriches results with
 last_edit_time, sorts by recency

- Parallel getTaskDetail calls after list to fetch last_edit_time and
  last_edit_user for each matched task
- Results sorted by last_edit_time descending (most recently modified first)
- Timestamp formatted as "YYYY-MM-DD HH:MM:SS" for readability

Enables queries like: "find the most recently modified draft Python task"
  cz-cli task search --type PYTHON --status draft

Subject: [PATCH 412/521] fix: limit getTaskDetail concurrency to 20 in task
 search

Add pMap() helper for rate-limited parallel execution.
Replaces Promise.all with pMap(..., 20) so task search never
fires more than 20 concurrent getTaskDetail requests regardless
of --limit value, preventing server overload at scale.

Subject: [PATCH 413/521] feat: task search add --folder, --owner, --sort; use
 locale for aiMessage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Filters added to task search:
- --folder <name|id>: recursive folder filter via location field
- --owner <username>: filter by owner/last-editor (fuzzy, client-side)
- --sort <last_edit|name|type>: configurable sort order

aiMessage i18n:
- Add task_search_result and task_stats_result keys to locale.ts
- Replace hardcoded Chinese strings with t() calls in task search/stats
- Messages now respect system locale (zh → Chinese, others → English)

Subject: [PATCH 414/521] fix: task stats --folder now counts tasks recursively
 across subfolders

Previously listTasks with folderId only counted direct children, giving 0
for folders that only contain subfolders.

New approach:
- BFS to collect all descendant folder ids (inclusive of root)
- Parallel listTasks(pageSize=1) for each folder id, sum totals
- folderCount in output reflects recursive subfolder count
- Output includes folder_count_recursive field when --folder is used

Subject: [PATCH 415/521] feat: add task schedule-detail, downstream,
 cron-preview commands

schedule-detail <task>
  - Shows deployed (published) schedule state via /scheduleTask/getDetail
  - Distinct from 'task content' which shows draft config
  - Useful for checking cron, next run time, last run result

downstream <task>
  - Lists all downstream tasks (flattened) via flatAllDownstream API
  - Supports impact analysis: "what breaks if I change this task?"

cron-preview <cron>
  - Previews upcoming run times for a cron expression
  - Accepts 5/6/7 field cron, auto-normalizes via normalizeCron()
  - Options: --count (default 5), --start HH:MM, --end HH:MM

Subject: [PATCH 416/521] feat: add task create-and-setup and task status
 high-level commands

create-and-setup <name>
  Combines create + save-content + save-cron in one command, reducing
  a 4-step agent workflow to 1 step.
  Options: --type, --folder, --content/--file, --cron, --vc, --schema,
           --description, --params

status <task>
  Returns draft config + deployed schedule state in one call (parallel
  getTaskDetail + getTaskConfigDetail + scheduleTask/getDetail).
  Eliminates the need to know whether to use 'content' or
  'schedule-detail'; deployed field is null-safe if not yet published.

task create & create-and-setup:
- --folder is now required; omitting it errors with clear message
- folder_id=0 (root directory) is explicitly rejected to prevent
  workspace pollution
- Duplicate name check: if a task with the same name exists in the
  target folder, error with task_id hint instead of silently creating

create-and-setup:
- try-finally rollback: if save-content or save-cron fails, the
  already-created task is auto-deleted so no orphan tasks are left
- Warn to stderr when neither --content/--file nor --cron is provided

task deploy:
- Pre-deploy check for script tasks (SQL/Python/Shell/JDBC): if
  schedule config has not been saved (hasConfig=false), error with
  actionable message instead of cryptic server error

Subject: [PATCH 418/521] fix: allow explicit root folder with warning instead
 of hard error

When user explicitly passes --folder 0, allow creation but warn to
stderr that root directory is not recommended. Hard error only when
--folder is omitted entirely (unintentional omission).

This distinguishes intentional root-dir creation from accidental
workspace pollution.

Subject: [PATCH 419/521] feat: add task folder-tree command; improve create
 folder guidance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

folder-tree:
- Returns full workspace folder hierarchy in one call (BFS recursive)
- Each entry has id, name, path (full slash-separated path), indent
- ai_message tells Agent exactly how to use the id with --folder
- Replaces multiple manual list-folders + parent queries

create / create-and-setup:
- Missing --folder error now says: "Run 'cz-cli task folder-tree' to
  see available folders and their IDs" — Agent can self-recover
  without asking the user

Subject: [PATCH 420/521] fix: folder-tree gives actionable guidance when
 result is empty

When no folders are found, distinguish two possible causes:
1. No folders exist yet in the workspace
2. Account may lack folder read permissions

Suggest next steps: create-folder first, or use --folder 0 as fallback.

Subject: [PATCH 421/521] feat: JDBC task datasource binding via save-content
 and create-and-setup

SDK:
- SaveTaskContentParams gains optional adhocConfigs: string field
- saveTaskContent passes adhocConfigs to saveDataFileConfiguration

CLI task save-content:
- New options: --datasource <name|id>, --database <schema>
- When --datasource is provided, resolves dsType via resolveDatasource()
  and writes adhocConfigs JSON to task detail
- Persisted binding is then auto-used by task execute (existing behavior)

CLI task create-and-setup:
- Same --datasource / --database options for JDBC tasks
- Datasource binding applied during Step 2 (save-content)

Verified: ds_id, ds_type, session_schema_name all correctly stored
and readable via task content after save.

Subject: [PATCH 422/521] fix: three robustness improvements for task lifecycle

1. create-and-setup: UI_ONLY task types skip save-content/save-cron
   Types: SPARK/FLOW/INTEGRATION/REALTIME/DYNAMIC_TABLE/STREAMING/
   FULL_INCREMENTAL/MULTI_REALTIME/MULTI_DI/DATABRICKS_*
   Returns studio_url and instructs user to configure in Studio UI.

2. deploy: show cron expression in confirmation prompt
   Before deploying, fetches schedule config and displays the cron
   so user can verify it's correct before schedule takes effect.
   Prevents accidental deploy of misconfigured schedules.

3. task execute: aiMessage clarifies --param scope
   Explicitly states that --param values are ad-hoc only; scheduled
   runs use paramValueList saved via 'task save-content --params'.

Subject: [PATCH 423/521] feat: task execute --save-params persists ad-hoc
 params to scheduled runs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New option: --save-params
When provided alongside --param KEY=VAL flags, after successful execution
the param values are written back to the task's paramValueList via
saveTaskContent so that scheduled runs use the same values.

This closes the gap between ad-hoc testing and scheduled execution:
  cz-cli task execute my_task --param city=shanghai --save-params
  → runs with city=shanghai this time AND saves it for future schedules

aiMessage updated to reflect whether params were persisted or not.
Persistence failure is non-fatal (caught silently).

Subject: [PATCH 424/521] feat: add task save-cdc command for CDC multi-table
 real-time sync

Implements configuration of MULTI_REALTIME (type=281) tasks via
/ide-admin/v1/ai/mcp/saveCdcTask endpoint (discovered from cz-mcp-server).

SDK:
- saveCdcTask() function with SaveCdcTaskParams interface

CLI task save-cdc <task>:
  --source <name|id>      Source datasource (MySQL/PostgreSQL/etc.)
  --database <schema>     Source database to sync
  --tables <t1,t2,...>    Specific tables (omit for whole-database mirror)
  --target <name|id>      Target Lakehouse datasource (auto-detected if omitted)
  --pipeline-type <n>     1=multi-table mirror, 2=merge, 3=whole-db (default)
  --sync-mode <n>         1=full+incremental (default), 2=incremental only

Auto-behaviors:
- If --tables specified and --pipeline-type=3 (default), auto-switches to 1
- If --target omitted, auto-resolves first Lakehouse datasource in workspace

Full workflow:
  cz-cli task create "my_cdc" --type MULTI_REALTIME --folder MyFolder
  cz-cli task save-cdc my_cdc --source mysql_ds --database mydb
  cz-cli task deploy my_cdc -y

Subject: [PATCH 425/521] fix: improve deploy error messages for sync task
 types

Before deploying, check sync task type and give actionable guidance:
- MULTI_REALTIME (281): error if not configured via 'task save-cdc'
- MULTI_DI (291) / FULL_INCREMENTAL (280): warn that source/target
  must be configured in Studio UI first (not a hard block)
- Other UI_ONLY types: no extra check (server error is clear enough)

Also documents CLI capability boundary:
- MULTI_REALTIME: fully supported via task save-cdc
- INTEGRATION single-table: complex column mapping, use cz-cli agent run
- MULTI_DI / FULL_INCREMENTAL: no public API, Studio UI required

 before deploy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

INTEGRATION/REALTIME/STREAMING/FULL_INCREMENTAL/MULTI_DI all show:
  Warning: <type> task — source/target/field-mapping must be configured
  in Studio UI before deploying. Open: <studio_url>

This is consistent with MULTI_DI/FULL_INCREMENTAL behavior.
Removed the special-case "use cz-cli agent run" recommendation which
was confusing — Studio UI guidance is clearer for all these types.

Subject: [PATCH 427/521] feat: add task save-integration for INTEGRATION
 single-table offline sync
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Auto-generates field mapping from source table metadata without
requiring Studio UI configuration.

Approach:
1. Fetch source table columns via datasource metadata API
2. Map source types → Lakehouse types using embedded type mapping table
   (MySQL/PG/SQLServer/Hive/ClickHouse/Oracle → Lakehouse)
3. Build integration config JSON (templateKey/sourceConnection/
   sinkConnection/jobs with columns + columnMapping)
4. Save as dataFileContent via saveTaskContent + adhocConfigs for VC

Type mapping covers:
- String types: VARCHAR/CHAR/TEXT/CLOB/NVARCHAR/etc → string
- Integers: TINYINT/SMALLINT/INT/BIGINT with UNSIGNED promotion
- Floats: FLOAT/DOUBLE/DECIMAL/NUMERIC/MONEY
- Dates: DATE/TIME/DATETIME/TIMESTAMP → date/time/timestamp_ltz
- Boolean: BOOL/BOOLEAN/BIT → boolean
- Binary: BLOB/BINARY/BYTEA/VARBINARY → binary
- Pattern fallbacks for unknown types

Usage:

Subject: [PATCH 428/521] refactor: split save-integration into
 integration-schema + save-integration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removes static type mapping table — type conversion is now Agent's responsibility.

integration-schema <task>:
  Fetches source table column metadata and returns it alongside
  source/target datasource info. Agent reads this, applies type mapping
  using Lakehouse data type docs, then produces the config JSON.
  aiMessage guides Agent to next step.

save-integration <task> --config '<json>':
  Accepts the complete integration config JSON (agent-generated),
  validates required fields, and saves via saveTaskContent.
  Decoupled from type inference logic entirely.

Workflow:
  1. cz-cli task integration-schema <task> --source <ds> --source-db <db> --source-table <t>
  2. Agent maps types using Lakehouse docs → produces config JSON
  3. cz-cli task save-integration <task> --config '<json>'
  4. cz-cli task deploy <task> -y

Subject: [PATCH 430/521] fix: INTEGRATION task deploy and save-integration
 error recovery

deploy:
- INTEGRATION (type=1) now checks fileContent non-empty before deploy
- Error message includes exact recovery commands with task_id pre-filled:
    cz-cli task integration-schema <id> --source ...
    cz-cli task save-integration <id> --config '<json>'

save-integration:
- After save, reads back fileContent to verify server actually stored it
- Reports SAVE_FAILED if content is empty or not valid JSON
- Prevents silent failures when server ignores malformed config

Subject: [PATCH 431/521] fix: INTEGRATION deploy requires both field mapping
 AND schedule config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

INTEGRATION tasks need save-cron just like SQL/Python tasks.

deploy now checks in order for INTEGRATION (type=1):
1. fileContent non-empty → NO_INTEGRATION_CONFIG (with full recovery steps)
2. hasConfig → NO_SCHEDULE_CONFIG (with save-cron command pre-filled)

save-integration aiMessage updated to include save-cron as next step.

Subject: [PATCH 432/521] feat: integration-schema returns target table check,
 splitPk hint, full user confirm checklist

New data in response:
- target.table_exists: bool (checks if Lakehouse target table already exists)
- target.existing_columns: columns if table exists (for diff review)
- recommendations.split_pk: inferred from primary key or first numeric col
- recommendations.write_mode/parallelism/where: defaults for user confirmation

aiMessage now includes a structured checklist Agent MUST confirm with user:
1. Target schema/table (required)
2. Table creation + partition columns if not exists
3. Write mode (APPEND/OVERWRITE)
4. splitPk recommendation
5. where filter (optional)
6. parallelism
7. Sync VCluster check with SQL + creation hint if none exists

Also added autoResolveLakehouseDs() workspace-aware matching (picks
LAKEHOUSE_<workspace_name> over arbitrary first result).

Subject: [PATCH 433/521] feat: integration-schema returns
 source_params_template per datasource type

Different source datasource types require different source.params:
- Relational DB: table + database in params (MySQL/PG/SQLServer/Oracle)
- Hive (3): NO table/database in params (only in dataObject/namespace)
- Kafka (2): topic, groupId, offset params
- OSS (9): path, fileType, encoding params
- MongoDB (12): table (collection), database params

Response includes source_params_template.note + .params.
aiMessage references source_params_template.params for config JSON.

Subject: [PATCH 435/521] fix: adhocVcId uses VC name string for Sync VCluster
 resolution
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For INTEGRATION/CDC/Sync task types, the Flink engine resolves
VCluster by name when adhocVcId is a string (VC name = VC ID).
Previously hardcoded adhocVcId=0 caused 'virtual cluster 0 not found'.

SDK: ExecuteAdhocParams.adhocVcId changed to number | string
CLI: adhocVcId now set to vcCode (the VC name) instead of 0

Verified: 'Deploying yarn application on cluster' succeeds with
PORTAL_SYNC_VC — VC correctly resolved by name.

Subject: [PATCH 436/521] fix: INTEGRATION task execute resolves VC name to
 numeric ID via vcluster/list API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add resolveVclusterId() to SDK execute.ts: calls /clickzetta-lakeconsole/api/v1/vcluster/list
  to map VC name → numeric ID (mirrors frontend behavior)
- Add listVclusters() for fetching all VCluster info
- Add etlVcCode/etlVcId params to ExecuteAdhocParams and executeAdhoc call
- In task execute: fetch connectionParam via getTaskConfigDetail in parallel with getDetail
  to retrieve etlVcCode/etlVcId (not returned by getDetail alone)
- For INTEGRATION task types: resolve adhocVcId to numeric ID before calling executeAdhoc
- Remove duplicate INTEGRATION_FILE_TYPES/execFileType declarations

Subject: [PATCH 437/521] fix: save-integration and save-cron now resolve
 etlVcId from vcluster/list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- save-integration --vc: calls resolveVclusterId() to map VC name → numeric ID,
  then saves etlVcCode + etlVcId via saveTaskConfig (scheduler also needs the ID)
- save-cron --vc: same resolveVclusterId() lookup for etlVcId
- SaveTaskConfigParams.etlVcId: widen to number | string (vcluster IDs are large int strings)
- saveTaskConfig: use spread for activeStartTime/activeEndTime so undefined skips the field
  (server rejects malformed date strings when field is present)

Subject: [PATCH 438/521] fix: save-integration only updates etlVcId when cron
 already exists
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Skip the saveTaskConfig call in save-integration when the task has no
existing cronExpress — a new task has no cron yet and the server rejects
the call with "cron表达式非法". The save-cron command handles setting
cron + etlVcCode + etlVcId together for new tasks.

Subject: [PATCH 439/521] feat: integration-schema smart config inference and
 column alignment check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Infer write_mode + where from source columns:
  update_time/updated_at/gmt_modified → APPEND + "col >= '\${bizdate}'"
  create_time/created_at → APPEND + "col >= '\${bizdate}'"
  no time column → OVERWRITE (full reload)
- Column alignment check when target table exists:
  detect missing columns and type mismatches, emit ALTER TABLE SQL in ai_message
  handle Lakehouse physical type aliases (int64=bigint, int32=int, etc.)
- splitPk validation: annotate whether recommended key is a true primary key
- Partition suggestion when target does not exist and source has time column
- ai_message restructured: inferred results shown first, only ambiguous items
  go to user confirmation

Subject: [PATCH 440/521] feat: integration-schema DB-specific where format,
 splitPk, and partition size guidance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add DB type groups: MYSQL_LIKE, PG_LIKE, ORACLE_LIKE, SS_LIKE, NO_SPLITPK, NO_WHERE
- where clause format per DB family:
  PostgreSQL/Greenplum/Redshift: col >= '${bizdate}'::date
  Oracle/DB2: col >= TO_DATE('${bizdate}', 'YYYY-MM-DD')
  MySQL/SQLServer/ClickHouse/Doris: col >= '${bizdate}'
- splitPk: skipped for Kafka/MongoDB/ES/Redis/DynamoDB (not supported)
- Incremental inference: skipped for streaming/object-store types (Kafka, OSS, S3, Redis)
- source_params_template.note: DB-specific guidance per type (Hive/Kafka/OSS/MongoDB/Oracle/PG/SS/MySQL)
- Partition suggestion: add size_warning (>500万 rows), granularity hint from table name,
  and day-vs-month guidance based on expected row density
- partition_suggestion and col_alignment now also exposed in data response (not only ai_message)

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- SRC_TO_LH: add ARRAY→array, MAP→map, STRUCT→struct (pass-through with element types)
- Column alignment: complex types matched by prefix (array<int> matches array)
- Type mapping rules in ai_message: document ARRAY<T>/MAP<K,V>/STRUCT<f:T> mappings
  with note that Lakehouse uses same syntax as Hive source

Subject: [PATCH 442/521] feat: integration-schema replace type mapping rules
 with LLM-friendly principles

Replace enumerated type mapping table with principled descriptions:
- Numeric/String/Time/Complex type principles instead of fixed lookup
- Key rules: UNSIGNED promotion, DATETIME vs TIMESTAMP timezone distinction,
  prefer wider types when uncertain
- Lets the calling LLM reason about edge cases rather than pattern-matching a table

Subject: [PATCH 443/521] refactor: replace hardcoded thresholds with
 LLM-friendly principles in integration-schema

- Partition: remove specific row-count thresholds, replace with principle
  (beneficial when queries filter by time range and table is large enough)
- Granularity: principle-based (coarsest that gives useful pruning) instead of day/month rules
- bizdate: remove 'previous day date' hardcoding, ask user to confirm date range intent
- splitPk absent: remove 'single-thread read' prescriptive note, suggest user confirms
- splitPk present: ask user about parallelism rather than asserting it helps

Subject: [PATCH 444/521] fix: handle PostgreSQL native types in
 integration-schema column alignment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- _text/_int4/_bool etc (PG underscore-prefix array types) → array<element_type>
- int4/int8 → int/bigint, float4/float8 → float/double
- timestamptz → timestamp_ltz (explicit alias)
- serial/bigserial → int/bigint
- pgvector 'vector' type → string in alignment check + note to LLM to use VECTOR(FLOAT, dim)
- Type mapping principles: add PG native type guidance including underscore-array convention

Subject: [PATCH 445/521] fix: splitPk only recommended when table has explicit
 primary key
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Without a primary key, any fallback numeric column guess is unreliable —
the LLM should ask the user instead. Only columns with primary=true get
recommended as splitPk; tables without a PK return split_pk=null.

Subject: [PATCH 446/521] fix: comprehensive PostgreSQL native type mapping in
 integration-schema
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Handle full range of PG-specific types:
- bpchar → string, name → string, uuid → string
- tsvector/tsquery/interval/timetz → string (no direct Lakehouse equivalent)
- oid/xid/cid → bigint, varbit → binary, jsonb → json
- int2/smallserial → smallint
- _xxx array element type now recursed through normalizeSrcType
  (e.g. _float4 → array<float> instead of array<_float4 literal>)

Subject: [PATCH 447/521] fix: use timestamp instead of timestamp_ntz for
 INTEGRATION sink columns
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

INTEGRATION sync engine rejects timestamp_ntz as sink column type
(confirmed by E2E: "Sink unsupported type: timestamp_ntz").
Use timestamp for all datetime sink columns.

- SRC_TO_LH: DATETIME/TIMESTAMP → timestamp
- normalizeSrcType: PG TIMESTAMP/TIMESTAMPTZ → timestamp
- Type mapping principle: note that timestamp_ntz is unsupported in INTEGRATION sink

Subject: [PATCH 448/521] fix: include inferred where and splitPk directly in
 source_params_template.params

Previously where/splitPk were only in recommendations and ai_message hints,
so agents building the config JSON could easily omit them. Now they're
pre-filled in source_params_template.params so the template is ready to use.

Subject: [PATCH 449/521] feat: add task start/stop commands for CDC/streaming
 tasks

New commands:
- cz-cli task start <task>: calls /ide-admin/v1/timelyTask/micro/start
- cz-cli task stop <task>: calls /ide-admin/v1/timelyTask/micro/stop

API discovered from Studio browser DevTools capture.
These control MULTI_REALTIME (281), REALTIME (14), STREAMING (17) tasks.

Also: task status shows cdc_status/cdc_task_id for CDC-type tasks
using deployStatus field (0=not_deployed 1=deployed 2=running 3=stopped 4=failed)

Subject: [PATCH 450/521] feat(task): expose CDC startup params as CLI options,
 fix real-time run status
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- task start: add --startup-mode (0/1/4), --engine-type, --snapshot,
  --snapshot-pool-size, --blacklist-strategy, --config options
- task start --startup-mode 4: accepts JSON --config for custom binlog
  position (by timestamp or file+offset)
- SDK: CdcTaskStartParams extended with full startupParams fields and
  CdcStartupPositionConfig type for custom position
- task status: CDC tasks now show real run state (运行中/停止) by calling
  /timelyTask/getDetail with timelyId (cdcTaskId), falls back to
  deployStatus when task is not running

Subject: [PATCH 452/521] feat(task): PG CDC slot auto-detection,
 listPgSlots/listPgPublications SDK

- save-cdc: add --slot-name and --logic-plugin options for PG sources
- PG auto-detect: when --slot-name omitted, query slotList API and use
  first available slot; error with creation hint if none found
- SDK: add listPgSlots(), listPgPublications(), checkCdcTables() functions
- SDK: SaveCdcTaskParams.sourceDatasourceList now accepts slotName/logicPlugin

Subject: [PATCH 453/521] feat(datasource): add check-cdc command; save-cdc
 auto prereq check

- datasource check-cdc <ds>: checks MySQL binlog (log_bin/binlog_format/
  binlog_row_image) via performance_schema.global_variables with WHERE
  filter; checks PG wal_level via pg_catalog.pg_settings + listPgSlots()
- apiSampleData: add `where` option for server-side row filtering
- save-cdc: auto-runs prereq check before configuring; use --skip-check
  to bypass (MySQL and PG only; other types skipped automatically)
- CDC supported source types: MySQL, TiDB, Aurora MySQL, PolarDB MySQL,
  PostgreSQL, Aurora PG, PolarDB PG, Greenplum, Redshift

Subject: [PATCH 454/521] feat(task): add create-multi-realtime command (prereq
 check + create + configure in one step)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- task create-multi-realtime <name>: checks CDC prerequisites first, then
  creates MULTI_REALTIME task (type=281), saves CDC config, and optionally
  saves VC config — all in one command
- Supports same options as save-cdc: --source, --database, --tables,
  --target, --vc, --slot-name, --logic-plugin, --pipeline-type,
  --sync-mode, --skip-check
- PG: auto-detects replication slot from listPgSlots API
- Prereq check runs before any task is created, giving early feedback

Subject: [PATCH 455/521] feat(datasource): add SQL Server and DM CDC
 prerequisite checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- datasource check-cdc: add SQL Server (dsType=8) check — verifies
  sys.databases.is_cdc_enabled=1 and SQL Server Agent is Running
- datasource check-cdc: add DM 达梦 (dsType=26) check — verifies
  ARCH_MODE=1 and SUPPLEMENTAL_LOG_DATA_MIN=YES via V$DATABASE
  (both marked as not tested — no environment available)
- task.ts: extract checkCdcPrereqs() helper to eliminate duplicate
  check logic between save-cdc and create-multi-realtime; both now
  cover MySQL/PG/SQL Server/DM uniformly via the helper

Subject: [PATCH 457/521] feat(task): add create-multi-di command for MULTI_DI
 offline batch sync

- create-multi-di: one-step create + configure MULTI_DI (type=291) task
  with prereq check, content save (groupingStrategy/writeMode params),
  and optional cron/VC config
- Options: --batch-size, --connections, --parallelism, --pk-write-mode,
  --non-pk-write-mode, --cron, --vc, --skip-check
- deploy: extend hasConfig check to cover both 281 (MULTI_REALTIME) and
  291 (MULTI_DI) with type-specific error messages

Subject: [PATCH 458/521] feat(task): support REALTIME (type=14) single-table
 streaming start/stop/status

- SDK: add startRealtimeTask() and stopRealtimeTask() using
  /timelyTask/startTimelyTask and /timelyTask/stopTimelyTask APIs
- task start/stop: detect fileType=14 and dispatch to the correct API
  (REALTIME uses timelyId=fileId directly, MULTI_REALTIME uses micro/start)
- task status: REALTIME (14) queries run status with fileId directly;
  MULTI_REALTIME (281) continues to use cdcTaskId

- create-realtime: one-step create + configure REALTIME task
  with Kafka system columns, target table check, DDL hint, and
  automatic cron/VC config save
- Options: --source, --topic, --target, --target-schema, --target-table,
  --vc, --mode, --codec, --group-id, --parallelism, --cron
- DDL hint uses plain CREATE TABLE (no USING DELTA for internal tables)
- Validates Kafka/AutoMQ source (dsType=2/45) and Lakehouse-only target
- write mode fixed to APPEND (only supported mode for streaming)

Subject: [PATCH 460/521] fix(task): create-realtime adhocConfigs includes VC,
 fixes create-multi-di scope error

- create-realtime: adhocConfigs now correctly includes adhocVcCode/adhocVcId
  (VC config is effective, not stripped)
- create-realtime: saveTaskConfig always called (required for deploy),
  even without explicit --cron (defaults to '0 0 2 * * ? *')
- create-multi-di: fix adhocConfigs schema to use literal "public" instead
  of out-of-scope targetSchema variable
- DDL hint: remove USING DELTA (not supported for internal tables)

Subject: [PATCH 461/521] refactor(task): rename sync commands for clarity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- create-multi-realtime → create-multi-table-realtime-sync
- create-multi-di → create-multi-table-batch-sync
- create-realtime → create-single-stream-sync

Names now clearly convey table count (single/multi) and sync mode
(realtime/batch/stream), eliminating ambiguity.

 command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Creates an INTEGRATION task and fetches source schema in one step.
Output includes source_columns, target table existence check, and
ai_message with exact next-step commands (integration-schema for full
recommendations, save-integration, save-cron, deploy).

Agent workflow: create-single-table-batch-sync → integration-schema
(optional, for full splitPk/where recommendations) → save-integration
→ save-cron → deploy.

Subject: [PATCH 463/521] refactor(task): rename save-integration and save-cdc
 for consistency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- save-integration → save-single-table-batch-sync
- save-cdc → save-multi-table-realtime-sync

All internal references (logOperation, aiMessage, help text) updated.
Command names now consistently reflect table count and sync mode,
matching the create-xxx-sync naming convention.

Subject: [PATCH 464/521] refactor(task): rename ambiguous subcommands for
 agent clarity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- create → create-script-task (SQL/Python/Shell script tasks)
- create-and-setup → create-script-task-with-config
- integration-schema → get-single-table-batch-schema
- save-content → save-script-content
- save-config → save-schedule-config
- content/detail → get-task-content
- schedule-detail → deployed-schedule

All internal references (logOperation, aiMessage, help text) updated.
Agent can now clearly distinguish script tasks from sync tasks and
understand what each command does without reading descriptions.

Subject: [PATCH 466/521] refactor(task): shorten subcommand names, improve
 help descriptions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Renames for clarity and brevity:
- create-script-task → create
- create-script-task-with-config → create-setup
- create-multi-table-realtime-sync → create-realtime-sync
- create-multi-table-batch-sync → create-batch-sync
- create-single-stream-sync → create-stream-sync
- create-single-table-batch-sync → create-offline-sync
- get-single-table-batch-schema → offline-sync-schema
- save-single-table-batch-sync → save-offline-sync
- save-multi-table-realtime-sync → save-realtime-sync
- save-script-content → save-content
- save-schedule-config → save-schedule
- get-task-content → get-content
- deployed-schedule → schedule-info

Help descriptions updated to clearly distinguish task types.
All internal references updated.

Subject: [PATCH 467/521] fix(task): create-batch-sync always saves cron config
 required for deploy

saveTaskConfig was only called when --cron or --vc was provided, causing
deploy to fail with 'cron_expression cannot be null'. Now always called
with a default cron (0 0 2 * * ? *) matching create-stream-sync behavior.

Subject: [PATCH 468/521] fix(resolver): eliminate duplicate error output when
 task not found

fail() now uses handledError() which throws HandledCliError, causing
handlers to skip the catch block via isHandledCliError check. Previously
error() was called in fail() and again in the catch block, producing
two JSON error outputs for TASK_NOT_FOUND cases.

- createFlowNode/submitFlow: fix env always using sc.env (cn-*) instead of "prod"
- task flow bind: check duplicate before calling API, return friendly message
- task flow unbind: accept --upstream/--downstream names (resolve dep id from DAG)
- task flow run: add --param key=value support to override flow/node params
- task flow run: add getFlowParams call to populate node list from API
- task flow submit: use saveTaskConfig with dataFileVersion=-1, scheduleRateType=3,
  triggerType=1, fileType=500, connectionParam; poll getTaskDetail for status
- SDK studioRequest: add method param (default POST) for GET endpoints
- SDK getFlowDag/getFlowParams: use correct HTTP method
- SDK saveTaskConfig: add dataFileVersion, scheduleRateType, triggerType, fileType,
  dataFileName, fileDescription, useFlowConfig params
- SDK flow: replace submitFlow with executeFlow + getFlowParams

Subject: [PATCH 470/521] feat: flow node/task param configuration and run
 override

- node-save: add --param key=value to set node paramValueList
- flow run: fix --param override by fetching node detail for actual paramValueList
- SDK saveFlowNodeContent: accept paramValueList param (was hardcoded to [])
- SDK saveTaskConfig: add paramValueList field

Subject: [PATCH 471/521] feat: flow/task param configuration

- node-save: add --flow-param key for ref=2 (inherit from parent flow)
- save-schedule: add --param key=value to set task-level params via saveTaskContent
- flow run: fetch flow-level params from getTaskDetail (not getFlowParams which returns [])
- flow run: always fetch node params from getFlowNodeDetail for correct override

Subject: [PATCH 472/521] fix: node-save preserves existing content when only
 --param/--flow-param given

When --content/--file not provided, fetch existing node content via
getFlowNodeDetail before saving, preventing accidental content erasure.

Subject: [PATCH 473/521] fix: save-offline-sync support --flow-id for flow
 node configuration

When --flow-id is provided, uses saveDataFileConfiguration with
flowId+nodeId instead of saveTaskContent, and getFlowNodeDetail
for verification instead of getTaskDetail.

Subject: [PATCH 475/521] fix: add ai_message forward-chain guidance to all key
 commands

Flow node commands (create-node, node-save, node-save-config, bind, unbind,
submit): all were silent, now guide agent through the full setup sequence.

DDL guidance: replace inline shell-unsafe DDL strings with instruction to
write create_table_ddl from response to file and run 'cz-cli sql --file'.

Sync setup flows:
- create-offline-sync: add VC discovery step, datasource exploration hint,
  explicit CREATE TABLE sequencing before deploy
- offline-sync-schema: add CREATE TABLE step between save-offline-sync and deploy
- create-realtime-sync: note that save-realtime-sync is NOT needed
- save-realtime-sync: add task start to next-step guidance
- create-batch-sync: specify Sync VCluster type requirement for execute

Datasource commands:
- catalogs/objects: always emit ai_message with next-step command
- describe: add forward-chain to create-offline-sync
- check-cdc success: add forward-chain to create-realtime-sync

Subject: [PATCH 476/521] =?UTF-8?q?fix:=20code=20review=20issues=20?=
 =?UTF-8?q?=E2=80=94=20fileType=20unwrap,=20orphan=20task,=20NaN,=20resolv?=

- task start/stop: fix fileType unwrap using same defensive pattern as deploy
  (was using ?.taskDetail ?? data, now checks typeof before unwrapping)
- create-offline-sync: resolve datasources BEFORE creating task to avoid orphan
  task on failure (moved source/target DS resolution to before createTask call)
- save-offline-sync --flow-id: forward adhocConfigs to flow-node save request
  (VC and schema were silently dropped for flow-node path)
- resolver resolveTaskIdsForRunLookup: fix response key from tasks to list,
  matching resolveTaskId and the actual API response shape
- getCdcTaskRunStatus: guard against NaN when cdcTaskId is undefined
  (undeployed MULTI_REALTIME tasks have no cdcTaskId yet)
- saveFlowNodeContent: accept vcCode/schemaName params instead of hardcoding DEFAULT

+# DataGPT CLI 命名规范审查报告
+
+## 现有 cz-cli 命名模式（参考基准）
+
+| 模式 | 示例 |
+|---|---|
+| 简单 CRUD 动词 | `list`, `create`, `describe`, `drop`, `delete`, `update` |
+| 资源-名词式子命令 | `datasource catalogs`, `datasource objects` |
+| 状态/信息查看 | `workspace current`, `profile status`, `runs stats` |
+| 获取结果 | `job result`, `runs logs` |
+| 操作动词 | `execute`, `deploy`, `undeploy`, `refill`, `rerun`, `stop` |
+| 连接测试 | `datasource test` |
+| 异步模式 | `sql --sync`（用 flag 控制，不拆分独立命令） |
+| 分页 | `--page` / `--page-size` 选项（不拆分独立命令） |
+| 别名 | `["detail", "show"]` 数组语法，`["logs", "log"]` |
+
+---
+
+## 审查发现（按严重程度排列）
+
+### 阻断级 — 与现有命令直接冲突
+
+| # | 文档当前写法 | 应改为 | 原因 |
+|---|---|---|---|
+| 1 | `datasource verify` | `datasource test` | 现有 `datasource test` 已实现连接验证，同一概念应用同一动词。 |
+| 2 | `datasource list-databases` | `datasource catalogs` | 现有 `datasource catalogs <datasource>` 使用名词形式。 |
+| 3 | `datasource list-tables` | `datasource objects` | 现有 `datasource objects <ds> <catalog>` 已实现该功能。 |
+| 4 | `datasource list-columns` | **删除**，用 `datasource describe` | 现有 `datasource describe <ds> <catalog> <object>` 已返回列详情。 |
+| 5 | `datasource preview-table` | `datasource preview` | 遵循 `table preview <name>` 模式，仅保留动词。 |
+| 6 | `session get-answer` | `session result` | 遵循 `job result` 模式，用名词表示获取输出。 |
+| 7 | `session poll-answer` | `session wait` | 遵循 `runs wait <id>` 模式。 |
+| 8 | `datasource search` | **删除**，用 `datasource list --search` | 现有 `datasource list` 已支持 `--name` 过滤，加 `--search` 即可。 |
+| 9 | `datasource load-async` | `datasource load --async` | 遵循 `sql --sync` 模式，用 flag 控制，不拆命令。 |
+| 10 | `metric search` | `metric list` + 过滤选项 | 同 #8。 |
+
+### 高优 — 动词-名词复合形式应改为资源优先
+
+| # | 文档当前写法 | 应改为 | 原因 |
+|---|---|---|---|
+| 11 | `domain add-table` | `domain table add` | 资源优先模式，table 是被操作的资源。 |
+| 12 | `domain remove-table` | `domain table remove` | 同上。 |
+| 13 | `domain discover-joins` | `domain joins discover` | 资源优先。 |
+| 14 | `domain apply-joins` | `domain joins apply` | 资源优先。 |
+| 15 | `domain get-discover-joins-result` | `domain joins result` | 5 个词 → 3 个词，过于冗长。 |
+| 16 | `domain add-relation` / `remove-relation` | `domain relation add` / `domain relation remove` | 资源优先。 |
+| 17 | `domain list-relations` | `domain relation list` | 资源优先。 |
+| 18 | `domain list-relations-by-target` | `domain relation list --target-type X --target-id Y` | 用选项代替复合名称。 |
+| 19 | `table set-semantics` | `table semantics set` | 资源优先。 |
+| 20 | `table get-semantics` | `table semantics get` | 资源优先。 |
+| 21 | `table set-semantics-prop` | `table semantics prop` | 连字符过多。 |
+| 22 | `table batch-detail` | `table semantics list` | 对齐 `list` 模式。 |
+| 23 | `column set-virtual` | `column virtual set` | 资源优先。 |
+| 24 | `column compile-virtual` | `column virtual compile` | 资源优先。 |
+| 25 | `column remove-virtual` | `column virtual delete` | 资源优先，且 `remove` → `delete`。 |
+| 26 | `column list-virtual` | `column virtual list` | 资源优先。 |
+| 27 | `datasource query-tables` | `datasource tables` 或合并到 `objects` | 动词-名词复合形式。 |
+
+### 高优 — `--safe`/`--open`/`--paged` 等模式变体应改用 flag
+
+| # | 文档当前写法 | 应改为 | 原因 |
+|---|---|---|---|
+| 28 | `session create-safe` | `session create` | 当前 open flow 固定创建 safe session，不再暴露 safe 模式开关。 |
+| 29 | `session open` / `open-paged` | `session list --page N --page-size M` | 分页在现有 `datasource list` 中通过选项控制。 |
+| 30 | `session run-open` | `session run` | 当前 open flow 固定调用 `/open/text2insight/query`，不再暴露 open 模式开关。 |
+| 31 | `session stop-open` | `session stop` | 当前 open flow 固定调用 `/open/text2insight/stop`。 |
+| 32 | `metric calculate-async` | `metric calculate --async` | 与 `load --async` 模式一致。 |
+
+### 高优 — 动词选择不一致
+
+| # | 文档当前写法 | 应改为 | 原因 |
+|---|---|---|---|
+| 33 | `knowledge add` | `knowledge create` | `add` 用于向父资源添加子项。创建独立资源用 `create`（`schema create`、`table create`、`profile create`、`task create`）。 |
+| 34 | `knowledge remove` | `knowledge delete` | `remove` 用于从父资源中移除。删除独立资源用 `delete` 或 `drop`（`profile delete`、`schema drop`）。 |
+| 35 | `tenant is-allowed` | `tenant status` 或 `tenant allowed` | 遵循 `workspace current` / `profile status` 模式。 |
+
+### 中优 — 结构 / 命名冲突
+
+| # | 问题 | 建议 |
+|---|---|---|
+| 36 | `datagpt table` 与顶层 `table` 命令冲突 | 用户容易混淆。顶层 `table` 管理数据库表（DESCRIBE、DROP 等），`datagpt table` 做语义配置。建议重命名为 `datagpt semantics`（其子命令就是 `set`/`get` 语义）或 `datagpt dataset`（API 已使用 `--dataset-id`）。 |
+| 37 | `datagpt domain delete` vs `schema drop` | `delete` 可以（与 `profile delete` 一致），但应在 DataGPT 内部保持一致，不要混用 `delete` 和 `remove`。 |
+| 38 | `answer-builder` 顶层含连字符 | `ai-guide` 已使用连字符，此处一致。但名称偏长，可考虑 `builder` 或 `answer`。 |
+| 39 | `knowledge maintain` | 文档中语义不明。如果是更新操作，应叫 `knowledge update`。 |
+
+---
+
+## 总结
+
+文档中的命名问题可归纳为四类：
+
+1. **同一概念、不同动词** — 应使用 cz-cli 已有动词：`verify`→`test`、`get-answer`→`result`、`poll-answer`→`wait`、`add`→`create`、`remove`→`delete`
+
+2. **动词-名词复合形式** — 应重组为资源优先的子命令结构：`add-table`→`table add`、`set-semantics`→`semantics set`、`set-virtual`→`virtual set`、`discover-joins`→`joins discover`、`list-relations`→`relation list`
+
+3. **模式变体拆分独立命令** — 应合并或内聚到固定 open flow：`*-async`→`--async`、`*-paged`→`--page`；session 的 safe/open 变体由当前 open API 路径固定承载，不再暴露为 CLI flag
+
+4. **冗余命令** — 应合并到已有模式：`search`→`list --filter`、`list-columns`→`describe`、`list-tables`→`objects`、`list-databases`→`catalogs`
+
+老板给出的 `ask`→`run` 示例正是此类修改的典型代表——同一概念在 cz-cli 中已有对应动词时，优先沿用。

+## Context
+
+`task save-cron` 和 `task save-schedule/save-config` 通过 SDK 的 `saveTaskConfig` 调用 `/ide-admin/v1/dataFileConfiguration/saveDataFileConfiguration` 保存调度配置。SQL/集成任务保存调度配置时需要同步保存解析出的调度依赖和任务产出，否则 UI 调度配置可能缺少依赖、产出或执行集群 ID。
+
+Studio 前端使用 `/ide-admin/v1/dataFileConfiguration/parseDataFileDependencyOut` 根据任务内容、任务 ID、项目、工作空间和 schema 解析两类数据：
+
+- `fileOutputTableDTOS`: 当前任务的产出表。
+- `dataFileDependencyDTOS`: 当前任务依赖的上游调度任务。
+
+用户关心的字段是名称、工作空间、输出表名、调度周期、开始调度时间、添加方式、依赖策略和产出表。保存接口需要的内部 DTO 字段不作为本命令的主要用户输出。
+
+## Goals / Non-Goals
+
+**Goals:**
+- 新增一个 CLI 命令解析 SQL/集成任务的产出表和调度依赖。
+- 输出包含人可读字段，便于用户检查解析出的调度依赖和任务产出。
+- `task save-cron`、`task save-schedule/save-config` 保存 SQL/集成任务调度配置时自动解析并保存依赖、产出。
+- 保存调度配置时解析执行集群 ID，包括 `DEFAULT`。
+- 对非 SQL/集成任务返回稳定错误，不调用解析接口。
+
+**Non-Goals:**
+- 不在新命令里自动保存调度配置。
+- 不改变 `save-cron`、`save-schedule` 的默认保存行为。
+- 不要求保存命令消费 `task lineage` 的输出；保存命令自行调用解析接口。
+- 不支持 Flow、Python、Shell、JDBC、CDC 等任务类型的解析。
+- 不重新实现 SQL 解析逻辑，解析结果以 Studio API 为准。
+
+## Decisions
+
+1. 命令命名为 `task lineage <task>`。
+   - 选择该名称是因为 Studio API 名称是 `parseDataFileDependencyOut`，能直接表达“依赖 + 产出”两类结果。
+   - 备选 `parse-schedule` 含义过宽，容易被理解为解析 cron 或调度周期。
+
+2. 默认从任务详情读取内容，从调度配置读取 schema。
+   - 请求体字段为 `projectId`、`workspaceId`、`schemaName`、`dataFileContent`、`dataFileId`。
+   - 命令支持 `--schema` 覆盖 schema，支持 `--content` / `--file` 解析未保存内容。
+   - 若任务详情没有内容且用户未传内容，命令仍把空字符串交给解析接口，由服务端决定是否返回空结果或错误。
+
+3. 支持类型仅为 SQL 和集成任务。
+   - SQL 任务使用 `fileType=4`。
+   - 集成任务使用 `fileType=1`。
+   - 类型优先从 `dataFile/getDetail` 的 `fileType` 读取，避免依赖名称推断。
+
+4. 输出面向用户确认，保存流程保持独立。
+   - `outputs` 映射 `fileOutputTableDTOS`，重点包含 `output_table_name`、`ref_table_name`、`task_id`、`project_id`、`add_method`、`add_method_name`。
+   - `dependencies` 映射 `dataFileDependencyDTOS`，重点包含 `name`、`workspace`、`output_table_name`、`schedule_rate_type`、`schedule_start_time`、`add_method`、`add_method_name`、`dep_strategy`、`dependency_task_id`、`dependency_project_id`。
+   - `--format table`、`csv`、`text`、`jsonl` 使用拍平行输出，避免把依赖和产出藏在大 JSON 单元格里。
+   - 不输出 `save_payload`。保存命令自行解析并保存依赖/产出，不消费本命令输出。
+
+5. SDK 增加专用解析封装。
+   - `parseTaskDependencyOut(config, params)` 负责调用 `/ide-admin/v1/dataFileConfiguration/parseDataFileDependencyOut`。
+   - `SaveTaskConfigParams` 支持 `dataFileOutputListReqs?: unknown[]`，用于保存任务产出列表。
+
+6. 保存命令自动解析并保存调度依赖和任务产出。
+   - `task save-cron` 保存 cron 时，对 SQL/集成任务调用 `parseDataFileDependencyOut`，把解析出的 `dataFileDependencyDTOS` 和 `fileOutputTableDTOS` 转成保存请求。
+   - `task save-schedule/save-config` 保存非 cron 配置时同样自动解析；但用户显式传入 `--deps clear` 或 `--deps replace` 时，依赖列表以用户输入为准，任务产出仍使用解析结果。
+   - 保存任务产出时需要携带顶层 `ownerCnName` 和 `ownerEnName`，否则后端插入产出表可能失败。
+   - 保存执行集群时，`--vc`、全局 `--vcluster`、旧配置和 `DEFAULT` 依次作为集群 code 来源；只要有集群 code 且没有集群 ID，就尝试解析 `etlVcId`，包括 `DEFAULT`。
+
+## Risks / Trade-offs
+
+- Studio API 返回字段可能随任务类型变化 → CLI 只做薄映射，减少字段丢失风险。
+- `depStrategy` 不在解析接口示例中返回 → CLI 在保存字段里默认补 `0`，同时在展示结果里暴露该默认值，后续可由保存命令覆盖。
+- 集成任务内容是 JSON 字符串而不是 SQL → 命令不解析内容结构，直接传给 Studio API，行为与前端一致。
+- 现有 `save-config` 测试和源码 `save-schedule` 命名不一致 → 本次仅在相关测试触达时维持兼容别名，不扩大重构。

+## Why
+
+Studio SQL 任务和集成任务在保存调度配置前，需要先解析任务产出表和调度依赖。当前 CLI 只能手工维护依赖，不能复用 Studio 的解析接口，也不能明确给出保存调度配置所需的依赖、产出字段。
+
+## What Changes
+
+- 新增 `cz-cli task lineage <task>` 命令，调用 Studio `parseDataFileDependencyOut` 接口解析任务产出和调度依赖。
+- 命令仅支持 SQL 任务和集成任务；其他任务类型返回明确的不支持错误。
+- 解析结果保留 Studio 返回的原始依赖和产出信息，并输出面向用户确认的调度依赖、任务产出字段。
+- `task save-cron`、`task save-schedule/save-config` 保存 SQL/集成任务调度配置时自动调用解析接口，把解析出的依赖和产出随调度配置一起保存。
+- 保存调度配置时解析并保存执行集群 ID，包括 `DEFAULT` 集群。
+
+## Capabilities
+
+### New Capabilities
+- `task-dependency-output-parse`: Studio 任务依赖和产出解析命令，覆盖支持类型、解析入参、保存配置字段和错误场景。
+
+### Modified Capabilities
+- `cli-command-routing`: 新增 `task lineage` 子命令应被 CLI 路由识别，并出现在 `task --help` 中。
+
+## Impact
+
+- `packages/cz-cli/src/commands/task.ts`: 新增命令处理、任务类型校验、解析输出标准化。
+- `packages/clickzetta-sdk/src/studio/task.ts`: 新增解析接口封装，并支持保存产出列表。
+- `packages/cz-cli/test/*.test.ts`: 增加命令行为、保存自动解析和帮助信息测试。
+- Studio API: `/ide-admin/v1/dataFileConfiguration/parseDataFileDependencyOut`。

+- **AND** CLI MUST NOT put `outputs`, `dependencies`, or save payload JSON blobs into table cells
+
+### Requirement: 拒绝不支持的任务类型
+
+The parse command MUST reject task types other than SQL and integration before calling the parse API.
+
+#### Scenario: 非支持任务类型
+
+- **WHEN** 用户对 Python、Shell、JDBC、Flow、CDC 或其他非 SQL/集成任务执行 `cz-cli task lineage <task>`
+- **THEN** CLI MUST return `UNSUPPORTED_TASK_TYPE`
+- **AND** CLI MUST not call `/ide-admin/v1/dataFileConfiguration/parseDataFileDependencyOut`
+
+#### Scenario: 任务类型缺失
+
+- **WHEN** task detail does not include a usable `fileType`
+- **THEN** CLI MUST return `UNSUPPORTED_TASK_TYPE`
+- **AND** the error message MUST explain that only SQL and integration tasks are supported

将 task lineage 的位置参数说明改为 Task name or ID，并补充 help 测试和 OpenSpec 约束。

验证：
- cd packages/cz-cli && bun test ./test/e2e-help.ts
- openspec validate cli-command-routing --strict

- truncateLargeFields 按 format 区分行为：json/jsonl/csv 干净截断不插标记，
  table 格式在格子里显示 ...(N chars)
- 截断信息统一通过 ai_message 上报，包含受影响列名、原始长度及重定向到文件的完整用法
- job result 新增 --no-truncate 选项，与 cz-cli sql 行为对齐

- save-cron/save-config 默认保留已有依赖和产出，不自动调用解析接口
- 新增 --auto-lineage 显式启用依赖和任务产出解析
- 新增 --outputs/--output-tables 支持手工替换或清空任务产出

验证：
- cd packages/cz-cli && bun test test/task-save-config-validation.test.ts test/task-lineage.test.ts
- cd packages/cz-cli && bun test ./test/e2e-help.ts
- cd packages/cz-cli && bun typecheck
- openspec validate task-dependency-output-parse --strict
- openspec validate cli-command-routing --strict
- UAT: save-cron 默认保存 parseDataFileDependencyOut 调用 0 次
- UAT: save-cron --auto-lineage 触发 parseDataFileDependencyOut
- UAT: save-config --outputs replace 写入 parseType=1

+# agent-guide 规格说明
+
+## Purpose
+迁移 Python 版本 `ai-guide`、skill 文档生成、命令示例和 TOON 压缩相关规格。当前仓库不再提供顶层 `cz-cli ai-guide` 命令；AI 可消费命令元数据由 `packages/cz-cli/src/guide-builder.ts` 和捆绑/外部 skill 文档承担。
+
+## Requirements
+### Requirement: AI 指南来自共享命令元数据
+
+本需求 MUST 按以下场景执行。
+
+系统 SHOULD 通过共享的命令元数据生成 AI 指南和 skill 命令清单，避免手写多份命令库存。
+
+#### Scenario: 命令定义变更
+
+- **WHEN** 某个 yargs 命令的名称、用法、选项或示例发生变化
+- **THEN** AI 指南和生成的 skill 命令清单 SHOULD 从同一元数据源反映该变化
+- **AND** 不要求维护独立的 Python `_AI_GUIDE` 或 Click registry
+
+#### Scenario: 旧 ai-guide 命令被调用
+
+- **WHEN** 用户或脚本调用已废弃的 `cz-cli ai-guide`
+- **THEN** CLI SHOULD 返回明确的 usage error 或迁移提示
+- **AND** 提示用户改用当前 skill 文档、`cz-cli <command> --help` 或内部 guide 生成入口
+
+### Requirement: 命令条目包含可执行用法
+
+本需求 MUST 按以下场景执行。
+
+AI 指南中的每个非根命令条目 MUST 包含命令路径、类型、说明和用法签名。
+
+#### Scenario: 读取 Lakehouse 命令清单
+
+- **WHEN** agent 读取生成的命令清单
+- **THEN** `sql`、`schema`、`table`、`workspace`、`status`、`profile`、`task`、`runs`、`attempts`、`agent`、`job`、`setup`、`update`、`datasource`、`ai-gateway`、`analytics-agent` 等命令均可发现
+- **AND** 每个命令条目包含 `kind`，值为 `group` 或 `command`
+
+#### Scenario: 命令没有示例
+
+- **WHEN** 某命令尚未定义 examples
+- **THEN** 生成过程 MUST 省略 examples 或使用空数组
+- **AND** 不得因此失败或输出 null 污染
+
+### Requirement: 示例与 help 输出一致
+
+本需求 MUST 按以下场景执行。
+
+非平凡命令组和叶子命令 SHOULD 在 help 中展示可直接复制的 Examples。
+
+#### Scenario: sql help 展示读写示例
+
+- **WHEN** 用户执行 `cz-cli sql --help`
+- **THEN** Examples 中 SHOULD 包含只读查询、`--write` 写入、文件输入、变量替换或异步查询示例
+
+#### Scenario: task help 展示常用工作流
+
+- **WHEN** 用户执行 `cz-cli task --help` 或关键子命令 help
+- **THEN** help SHOULD 展示创建、保存内容、部署、执行或依赖解析的示例
+- **AND** 示例 MUST 使用当前命令名和 `--format`，不得使用 Python 时代的 `-o`
+
+### Requirement: 指南输出预算可控
+
+本需求 MUST 按以下场景执行。
+
+生成的 AI 指南 SHOULD 有长度预算，优先保留命令签名、安全规则、分页/确认契约和输出格式说明。
+
+#### Scenario: 内容超过预算
+
+- **WHEN** 生成内容超过配置预算
+- **THEN** 系统先裁剪低优先级描述、示例或参数详解
+- **AND** 输出包含 machine-readable truncation metadata
+
+#### Scenario: 宽模式生成
+
+- **WHEN** 调用方明确请求宽模式或更大预算
+- **THEN** 系统 MAY 保留更多选项和示例细节
+- **AND** 仍 MUST 保留 mandatory sections
+
+### Requirement: skill 文档生成与分发解耦
+
+本需求 MUST 按以下场景执行。
+
+skill 文档生成负责内容一致性，安装分发由 `skill-install` 规格约束。
+
+#### Scenario: 构建包包含 skill
+
+- **WHEN** release 构建打包 `skills/cz-cli/SKILL.md`
+- **THEN** 内容 SHOULD 反映当前命令清单和 onboarding 指引
+- **AND** 安装脚本负责注册到内置和外部 agent skill 目录
+
+#### Scenario: skill 文档过期
+
+- **WHEN** 生成器检测到命令清单与提交的 skill 文档不一致
+- **THEN** drift check SHOULD 失败并提示重新生成
+- **AND** 不能静默发布过期命令说明

+# agent-runtime-api 规格说明
+
+## Purpose
+迁移 Python 版本 agent chat 与 HTTP API 规格到当前 opencode/cz-cli agent runtime。当前用户入口是 `cz-cli agent`、`cz-cli agent run`、`cz-cli serve` 与 agent session 命令，不再是 `cz agent ask`。
+
+## Requirements
+### Requirement: agent run 提供单次自然语言入口
+
+本需求 MUST 按以下场景执行。
+
+CLI MUST 提供 `cz-cli agent run <prompt>`，用于向 agent runtime 发送单次自然语言请求并返回完成结果或会话 ID。
+
+#### Scenario: 单次请求完成
+
+- **WHEN** 用户执行 `cz-cli agent run "show tables"`
+- **THEN** CLI 创建或复用 agent session 并提交 prompt
+- **AND** 默认输出为人类可读格式，`--format json` 输出结构化事件或结果
+
+#### Scenario: LLM 未配置
+
+- **WHEN** 用户在未配置可用 LLM 时执行 `cz-cli agent run "..."`
+- **THEN** CLI 返回 `NO_ACTIVE_LLM` 指导
+- **AND** 指导必须区分 LLM 配置与 Lakehouse profile 配置
+
+### Requirement: agent status 通过 session 子命令表达
+
+本需求 MUST 按以下场景执行。
+
+当前 runtime SHOULD 通过 `cz-cli agent session status <sessionID>` 查询会话忙闲与最近进度，而不是 Python 旧版 `cz agent status` 健康检查。
+
+#### Scenario: 查询会话状态
+
+- **WHEN** 用户执行 `cz-cli agent session status <sessionID> --format json`
+- **THEN** CLI 返回 session 状态、最近 progress 和是否 idle/busy 的结构化信息
+
+#### Scenario: 等待会话空闲
+
+- **WHEN** 用户执行 `cz-cli agent session status <sessionID> --wait`
+- **THEN** CLI 阻塞并流式输出去重后的 NDJSON progress
+- **AND** 长时间无进展时返回 timeout 语义而非永久挂起
+
+### Requirement: headless server 透出 agent API
+
+本需求 MUST 按以下场景执行。
+
+`cz-cli serve` MUST 启动 headless agent server，并通过 opencode HTTP API 处理会话、消息、文件、技能和状态。
+
+#### Scenario: 启动 server
+
+- **WHEN** 用户执行 `cz-cli serve --hostname 127.0.0.1 --port 4096`
+- **THEN** CLI 启动 agent server 并输出监听地址
+- **AND** 服务端复用现有 opencode session/runtime，不重复实现 agent 逻辑
+
+#### Scenario: 端口不可用
+
+- **WHEN** 指定端口已被占用或 server 启动失败
+- **THEN** CLI 返回非零退出码和可诊断错误
+- **AND** 不吞掉底层启动失败原因
+
+### Requirement: 配置通过 profiles 与 LLM 配置分离
+
+本需求 MUST 按以下场景执行。
+
+Lakehouse profile 与 LLM provider 配置 MUST 分离：`[profiles.*]` 保存 ClickZetta 连接，`[llm.*]` 保存 agent 模型配置。
+
+#### Scenario: 选择 Lakehouse profile
+
+- **WHEN** 用户执行 `cz-cli agent run "..." --profile staging`
+- **THEN** agent 子进程将该 profile 的 ClickZetta 连接信息注入运行环境
+- **AND** 不改变默认 profile
+
+#### Scenario: 缺少 Lakehouse profile
+
+- **WHEN** agent 或工具需要执行 Lakehouse 命令但没有 profile
+- **THEN** CLI 返回 `NO_PROFILE` 或等价结构化指导
+- **AND** 提示 `cz-cli setup` 路径

+# ai-gateway 规格说明
+
+## Purpose
+定义 ClickZetta AIGW virtual key 与 model 浏览命令。该能力当前在 `cz-cli ai-gateway` 下，不属于旧 Python `ai-guide`。
+
+## Requirements
+### Requirement: ai-gateway 命令 help 签名稳定
+
+本需求 MUST 按以下场景执行。
+
+`ai-gateway` 命令族 MUST 暴露 key 和 model 两个子命令组。
+
+#### Scenario: ai-gateway group help
+
+- **WHEN** 用户执行 `cz-cli ai-gateway --help`
+- **THEN** help 显示 `key` 和 `model`
+- **AND** 全局连接与输出格式参数可用
+
+#### Scenario: 未知子命令
+
+- **WHEN** 用户执行 `cz-cli ai-gateway unknown`
+- **THEN** CLI 返回 usage error
+- **AND** 提示查看 help
+
+### Requirement: model list 默认限制并提示 agent
+
+本需求 MUST 按以下场景执行。
+
+model list SHOULD 默认限制返回数量，避免 agent 上下文膨胀，并通过 `ai_message` 提供继续分页/取消限制提示。
+
+#### Scenario: 默认限制
+
+- **WHEN** 用户执行 `cz-cli ai-gateway model list <key-or-alias>`
+- **THEN** CLI 默认最多请求/返回 10 个模型（或 help 声明的默认值）
+- **AND** `ai_message` 提示使用 `--limit` 或 `--no-limit`
+
+#### Scenario: 取消限制
+
+- **WHEN** 用户执行 `cz-cli ai-gateway model list <key-or-alias> --no-limit`
+- **THEN** CLI 请求完整模型列表
+- **AND** 大结果仍可通过输出格式和截断提示保护 agent 上下文
+
+### Requirement: virtual key 管理保护敏感值
+
+本需求 MUST 按以下场景执行。
+
+key 子命令 MUST 遮蔽 secret，只在创建时返回必要一次性信息。
+
+#### Scenario: 列出 key
+
+- **WHEN** 用户执行 `cz-cli ai-gateway key list --format json`
+- **THEN** 输出 key 元数据和 alias/status
+- **AND** 不泄露完整 secret
+

+### Requirement: 自动更新不受渠道限制
+
+本需求 MUST 按以下场景执行。
 
 自动更新应在任何真实安装上运行，不受发布渠道影响。启用条件由以下因素决定：更新未被禁用（通过配置 `autoupdate: false` 或环境变量 `CLICKZETTA_DISABLE_AUTOUPDATE` / `CZ_SKIP_UPDATE` / 一次性 `CLICKZETTA_SKIP_UPDATE_ONCE`），命令不在跳过列表中（`setup`、`update`、`uninstall`、`--help`/`-h`、`--version`/`-v`），已安装版本为有效发布版本（stable semver 或 `dev-v<major>.<minor>.<patch>.<timestamp>`），安装方式受支持，且检查间隔已到期。渠道值不应决定自动更新是否运行。

-### 需求：渠道选择更新流；安装方式不选择版本
+### Requirement: 渠道选择更新流；安装方式不选择版本
+
+本需求 MUST 按以下场景执行。
 
 发布渠道应是目标版本的唯一来源，始终从 cz-cli.ai 解析：`stable` 来自 `https://cz-cli.ai/api/stable`，`nightly` 来自 `https://cz-cli.ai/api/nightly`。安装方式不应影响版本解析——它仅选择升级机制（`stable` → `install.sh`；`nightly` → `install-nightly.sh`；托管包管理器使用其自身的安装命令）。特别地，版本解析不应查询 npm 仓库的 `latest` dist-tag，即使安装方式为 npm/pnpm/yarn/bun。`stable` 和 `nightly` 均可自动升级。

 - **THEN** 包管理器升级可能失败，系统回退到该渠道的安装脚本
 
-### 需求：双文件更新状态模型
+### Requirement: 双文件更新状态模型
+
+本需求 MUST 按以下场景执行。
 
 系统应维护两个独立文件。`~/.clickzetta/install.json` 是渠道/身份记忆，由每次安装和更新入口写入。`~/.local/state/clickzetta/update-check.json`（XDG state）仅由自动更新路径写入，记录 `last_checked_at`、`last_result` 和 `latest_version`。判断自动更新是否发生应依赖 `update-check.json`，而非 `install.json.updated_at`。
 
-#### 场景：手动更新不写入自动更新状态文件

+### Requirement: 通知与升级
+
+本需求 MUST 按以下场景执行。
 
 当有更新版本可用时，如果安装方式为受支持的托管方式之一（`curl`、`npm`、`pnpm`、`yarn`、`bun`）且自动更新已启用，系统应执行自动就地升级；否则应通知用户有更新可用。
 
-#### 场景：不受支持的方式执行通知

+### Requirement: 升级前事前清除遮蔽 binary
+
+本需求 MUST 按以下场景执行。
 
 在执行升级之前，系统应检测 `which cz-cli` 解析的路径是否会遮蔽新安装的 binary。如果该路径不在我们管理的安装目录中，应在升级前通过适当方式移除它，确保升级完成后 `which cz-cli` 立即指向新版本。

+# output-format 规格说明
+
+## Purpose
+定义 cz-cli 的机器可读与人可读输出契约。Python 版本历史上的 `-o/--output` 已废弃；当前 TypeScript/Bun 版本 MUST 使用 `--format`，并保留 `ai_message` 作为 agent 面向的下一步提示。
+
+## Requirements
+### Requirement: 输出格式统一使用 --format
+
+本需求 MUST 按以下场景执行。
+
+所有命令 MUST 使用全局或命令级 `--format` 选择输出格式。旧的 `-o` 与 `--output` MUST NOT 继续作为输出格式入口。

+
+### Requirement: TOON 输出按 token 友好结构渲染
+
+本需求 MUST 按以下场景执行。
+
+TOON 输出 MUST 尽量把同构标量对象数组压缩为表格形态，并避免因为可选嵌套字段破坏主数组压缩。
+
+#### Scenario: 同构标量数组压缩为表格
+
+- **WHEN** payload 的主数据是键集合一致且值均为标量的对象数组
+- **THEN** `--format toon` 输出 SHOULD 呈现 `key[N]{col1,col2}:` 形式
+- **AND** 不应退化为逐项冗长展开
+
+#### Scenario: 存在嵌套字段
+
+- **WHEN** 主数组中的某些字段是数组或对象，例如 command examples
+- **THEN** 渲染前 SHOULD 将这些异构字段移动到 sibling map
+- **AND** 若数据模型本身必须嵌套，允许局部展开但不能破坏关键字段可读性
+
+### Requirement: ai_message 作为 agent 指导保留
+
+本需求 MUST 按以下场景执行。
+
+结构化成功或错误 payload MAY 包含 `ai_message`；该字段 MUST 被视为给 agent 的下一步或截断提示。
+
+#### Scenario: JSON/pretty/toon 输出
+
+- **WHEN** 命令返回带 `ai_message` 的 payload

+- **AND** 调用方可以据此继续分页、调整参数或确认风险
+
+#### Scenario: 表格或行格式输出
+
+- **WHEN** 命令以 table/csv/text/jsonl 输出主数据
+- **THEN** CLI MAY 将 `ai_message` 写入 stderr 或结构化辅助字段
+- **AND** MUST NOT 因表格化而丢失重要下一步提示

+name: cz-cli-inner
+description: Use when answering operational ClickZetta Studio or Lakehouse requests from inside a cz-cli-aware agent, including listing metadata, running SQL, managing tasks, checking runs, or operating datasource and AI Gateway resources.
+---
+
+# cz-cli Inner
+
+Use `cz-cli` proactively for ClickZetta operational requests. Do not ask for information that can be discovered with `cz-cli` commands.
+
+## Core Rules
+
+- Use `cz-cli` from `PATH` for Lakehouse and Studio operations.
+- Run `cz-cli <command> --help` when exact flags are unclear.
+- Prefer `--format json` for machine-readable output and preserve `ai_message` guidance.
+- Use `--profile <name>` when the user names an environment or profile.
+- On `NO_PROFILE`, guide the user to run `cz-cli setup`.
+- Stop after the same command fails twice or repeated minor variations make no progress; report what failed and change approach or ask for guidance.
+- Never fabricate URLs, task IDs, run IDs, table names, or profile names. Use exact command output.
+
+## SQL Rules
+
+- Current default SQL mode is sync: `cz-cli sql "SELECT ..."` waits for results.
+- Use `--async` for large or long-running queries, then inspect with `cz-cli sql status <job-id>` or `cz-cli job status <job-id>`.
+- Write operations always require `--write`, including DDL and DML.
+- If SQL contains quotes, `$`, backticks, backslashes, or newlines, write it to a file and run `cz-cli sql -f <file>` to avoid shell corruption.
+- Use ClickZetta Lakehouse SQL syntax only. Before generating, modifying, validating, explaining, or running non-trivial Lakehouse SQL, load the Lakehouse documentation skill if available.
+
+## Studio Task Rules
+
+- Always pass `--type` when creating tasks.
+- Flow tasks use `cz-cli task flow *` commands for nodes; do not use normal task content/deploy commands on flow nodes.
+- Confirm intent before destructive or state-changing operations: deploy, undeploy, execute, delete, refill/backfill, stop, rerun, and similar actions.
+- For historical reruns or backfills, use `cz-cli runs refill <task> --from YYYY-MM-DD --to YYYY-MM-DD`; this is under `runs`, not `task`.
+- For output table JSON flags such as `--output-tables`, pass the JSON array as one shell argument, usually with single quotes.
+
+## Output Handling
+
+- `--format json`: best for parsing.
+- `--format toon`: line-per-field output, useful with `grep` or `head`.
+- `--format table`, `--format csv`, `--format pretty`: human-readable.
+- `--field <name>`: extracts one field as raw text.
+- Paginated list commands usually return page 1; check `ai_message` for next-page hints.
+
+## Command Reference
+
+Read `references/command-reference.md` when you need examples or command coverage beyond these core rules.

+# cz-cli Command Reference
+
+Use `cz-cli <command> --help` for authoritative options. This reference is a compact command map for common operations.
+
+## SQL and Jobs
+
+```bash
+cz-cli sql "<statement>"                  # Execute SQL, sync by default
+cz-cli sql "<statement>" --async          # Return job_id immediately for large/long-running queries
+cz-cli sql status <job-id>                # Check async SQL job status
+cz-cli job status <job-id>                # Job status and summary
+cz-cli job result <job-id>                # Fetch job result set
+cz-cli job profile <job-id>               # Flattened job profile basics; use --raw for raw content
+```
+
+## Schemas and Tables
+
+```bash
+cz-cli schema list [--like <pattern>]
+cz-cli schema describe <name>
+cz-cli schema create <name>
+cz-cli schema drop <name>
+
+cz-cli table list [--schema <name>]
+cz-cli table describe <name>
+cz-cli table preview <name>
+cz-cli table stats <name>
+cz-cli table history [name]
+cz-cli table create "<ddl>"
+cz-cli table drop <name>
+```
+
+## Workspaces and Profiles
+
+```bash
+cz-cli workspace current
+cz-cli status
+cz-cli profile list
+```
+
+## Studio Tasks
+
+```bash
+cz-cli task list
+cz-cli task create <name> --type <TYPE>       # SQL/PYTHON/SHELL/SPARK/FLOW
+cz-cli task content <task>                    # Draft script, config, and params
+cz-cli task save-content <task> --file <f>    # Save task script
+cz-cli task save-config <task>                # Save non-cron config: retry, deps, VC, schema, timeout
+cz-cli task save-cron <task>                  # Save cron schedule config
+cz-cli task lineage <task>                    # Parse outputs/dependencies; returns save_payload
+cz-cli task deps <task>                       # Draft dependencies
+cz-cli task deploy <task>                     # Publish/deploy; alias: online
+cz-cli task undeploy <task>                   # Undeploy; alias: offline
+cz-cli task execute <task>                    # Ad-hoc execution
+cz-cli task delete <task>                     # Delete draft/offline task
+cz-cli task flow dag <task>                   # Get flow DAG
+```
+
+For task params, `save-content` supports `--params '{"key":"val","dt":"bizdate","yd":"$[yyyy-MM-dd,-1d]"}'`. System params such as `bizdate`, `sys_plan_day`, and `sys_biz_datetime` are auto-detected.
+
+For manual output tables, quote JSON as one argument:
+
+```bash
+cz-cli task save-config <task> --outputs replace --output-tables '[{"outputTableName":"ws.table","refTableName":"ws.public.table"}]'
+```
+
+## Runs and Attempts
+
+```bash
+cz-cli runs list [--task <name>]
+cz-cli runs detail <id>
+cz-cli runs wait <id>
+cz-cli runs logs <id>
+cz-cli runs deps <task>                       # Published dependencies
+cz-cli runs stop <id>
+cz-cli runs refill <task> --from D --to D     # D is YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS
+cz-cli runs rerun <id>
+cz-cli runs stats
+
+cz-cli attempts list [id]
+cz-cli attempts log [id]
+```
+
+## Datasources
+
+```bash
+cz-cli datasource list [--type <type>] [--name <filter>]
+cz-cli datasource catalogs <name_or_id>
+cz-cli datasource objects <name_or_id> <catalog>
+cz-cli datasource describe <name_or_id> <catalog> <object>
+cz-cli datasource test <name_or_id>
+cz-cli datasource sample <name_or_id> <catalog> <object>
+```
+
+## AI Gateway
+
+```bash
+cz-cli ai-gateway key list
+cz-cli ai-gateway key create <alias>
+cz-cli ai-gateway key upsert <alias>
+cz-cli ai-gateway key get <ref>
+cz-cli ai-gateway key set-quota --ref R --period P --quota N
+cz-cli ai-gateway key enable <ref>
+cz-cli ai-gateway key disable <ref>
+cz-cli ai-gateway key delete <ref>
+cz-cli ai-gateway model list [ref]
+```
+
+Useful key flags:
+
+- `key list`: `--alias`, `--key`, `--status 1|0`, `--mine`, `--reveal`
+- `key create/upsert`: `--period daily|weekly|monthly|total`, `--quota N`, `--route-type default|provider|byok`, `--providers <id ...>`, `--provider-sort price|throughput|latency`, `--private-keys <alias ...>`, `--add-to-llm [name]`, `--use`
+- `key get`: `<ref>` can be an alias, masked key, or key value; supports `--add-to-llm [name]` and `--use`
+- `key delete`: `--remove-from-llm`

+# cz-cli Command Reference
+
+Use `cz-cli <command> --help` for authoritative options. This reference is a compact command map for common operations.
+
+## SQL and Jobs
+
+```bash
+cz-cli sql "<statement>"                  # Execute SQL, sync by default
+cz-cli sql "<statement>" --async          # Return job_id immediately for large/long-running queries
+cz-cli sql status <job-id>                # Check async SQL job status
+cz-cli job status <job-id>                # Job status and summary
+cz-cli job result <job-id>                # Fetch job result set
+cz-cli job profile <job-id>               # Flattened job profile basics; use --raw for raw content
+```
+
+## Schemas and Tables
+
+```bash
+cz-cli schema list [--like <pattern>]
+cz-cli schema describe <name>
+cz-cli schema create <name>
+cz-cli schema drop <name>
+
+cz-cli table list [--schema <name>]
+cz-cli table describe <name>
+cz-cli table preview <name>
+cz-cli table stats <name>
+cz-cli table history [name]
+cz-cli table create "<ddl>"
+cz-cli table drop <name>
+```
+
+## Workspaces and Profiles
+
+```bash
+cz-cli workspace current
+cz-cli status
+cz-cli profile list
+```
+
+## Studio Tasks
+
+```bash
+cz-cli task list
+cz-cli task create <name> --type <TYPE>       # SQL/PYTHON/SHELL/SPARK/FLOW
+cz-cli task content <task>                    # Draft script, config, and params
+cz-cli task save-content <task> --file <f>    # Save task script
+cz-cli task save-config <task>                # Save non-cron config: retry, deps, VC, schema, timeout
+cz-cli task save-cron <task>                  # Save cron schedule config
+cz-cli task lineage <task>                    # Parse outputs/dependencies; returns save_payload
+cz-cli task deps <task>                       # Draft dependencies
+cz-cli task deploy <task>                     # Publish/deploy; alias: online

+cz-cli task flow dag <task>                   # Get flow DAG
+```
+
+For task params, `save-content` supports `--params '{"key":"val","dt":"bizdate","yd":"$[yyyy-MM-dd,-1d]"}'`. System params such as `bizdate`, `sys_plan_day`, and `sys_biz_datetime` are auto-detected.
+
+For manual output tables, quote JSON as one argument:
+
+```bash
+cz-cli task save-config <task> --outputs replace --output-tables '[{"outputTableName":"ws.table","refTableName":"ws.public.table"}]'
+```
+
+## Runs and Attempts
+
+```bash
+cz-cli runs list [--task <name>]
+cz-cli runs detail <id>
+cz-cli runs wait <id>
+cz-cli runs logs <id>
+cz-cli runs deps <task>                       # Published dependencies
+cz-cli runs stop <id>
+cz-cli runs refill <task> --from D --to D     # D is YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS
+cz-cli runs rerun <id>
+cz-cli runs stats
+
+cz-cli attempts list [id]
+cz-cli attempts log [id]
+```
+
+## Datasources
+
+```bash
+cz-cli datasource list [--type <type>] [--name <filter>]
+cz-cli datasource catalogs <name_or_id>
+cz-cli datasource objects <name_or_id> <catalog>
+cz-cli datasource describe <name_or_id> <catalog> <object>
+cz-cli datasource test <name_or_id>
+cz-cli datasource sample <name_or_id> <catalog> <object>
+```
+
+## AI Gateway
+
+```bash
+cz-cli ai-gateway key list
+cz-cli ai-gateway key create <alias>
+cz-cli ai-gateway key upsert <alias>
+cz-cli ai-gateway key get <ref>
+cz-cli ai-gateway key set-quota --ref R --period P --quota N
+cz-cli ai-gateway key enable <ref>
+cz-cli ai-gateway key disable <ref>
+cz-cli ai-gateway key delete <ref>
+cz-cli ai-gateway model list [ref]
+```
+
+Useful key flags:
+
+- `key list`: `--alias`, `--key`, `--status 1|0`, `--mine`, `--reveal`
+- `key create/upsert`: `--period daily|weekly|monthly|total`, `--quota N`, `--route-type default|provider|byok`, `--providers <id ...>`, `--provider-sort price|throughput|latency`, `--private-keys <alias ...>`, `--add-to-llm [name]`, `--use`
+- `key get`: `<ref>` can be an alias, masked key, or key value; supports `--add-to-llm [name]` and `--use`
+- `key delete`: `--remove-from-llm`

+name: cz-cli-inner
+description: Use when answering operational ClickZetta Studio or Lakehouse requests from inside a cz-cli-aware agent, including listing metadata, running SQL, managing tasks, checking runs, or operating datasource and AI Gateway resources.
+---
+
+# cz-cli Inner
+
+Use `cz-cli` proactively for ClickZetta operational requests. Do not ask for information that can be discovered with `cz-cli` commands.
+
+## Core Rules
+
+- Use `cz-cli` from `PATH` for Lakehouse and Studio operations.
+- Run `cz-cli <command> --help` when exact flags are unclear.
+- Prefer `--format json` for machine-readable output and preserve `ai_message` guidance.
+- Use `--profile <name>` when the user names an environment or profile.
+- On `NO_PROFILE`, guide the user to run `cz-cli setup`.
+- Stop after the same command fails twice or repeated minor variations make no progress; report what failed and change approach or ask for guidance.
+- Never fabricate URLs, task IDs, run IDs, table names, or profile names. Use exact command output.
+
+## SQL Rules
+
+- Current default SQL mode is sync: `cz-cli sql "SELECT ..."` waits for results.
+- Use `--async` for large or long-running queries, then inspect with `cz-cli sql status <job-id>` or `cz-cli job status <job-id>`.
+- Write operations always require `--write`, including DDL and DML.
+- If SQL contains quotes, `$`, backticks, backslashes, or newlines, write it to a file and run `cz-cli sql -f <file>` to avoid shell corruption.
+- Use ClickZetta Lakehouse SQL syntax only. Before generating, modifying, validating, explaining, or running non-trivial Lakehouse SQL, load the Lakehouse documentation skill if available.
+
+## Studio Task Rules
+
+- Always pass `--type` when creating tasks.
+- Flow tasks use `cz-cli task flow *` commands for nodes; do not use normal task content/deploy commands on flow nodes.
+- Confirm intent before destructive or state-changing operations: deploy, undeploy, execute, delete, refill/backfill, stop, rerun, and similar actions.
+- For historical reruns or backfills, use `cz-cli runs refill <task> --from YYYY-MM-DD --to YYYY-MM-DD`; this is under `runs`, not `task`.
+- For output table JSON flags such as `--output-tables`, pass the JSON array as one shell argument, usually with single quotes.
+
+## Output Handling
+
+- `--format json`: best for parsing.
+- `--format toon`: line-per-field output, useful with `grep` or `head`.
+- `--format table`, `--format csv`, `--format pretty`: human-readable.
+- `--field <name>`: extracts one field as raw text.
+- Paginated list commands usually return page 1; check `ai_message` for next-page hints.
+

+- Flow tasks use `cz-cli task flow *` commands for nodes; do not use normal task content/deploy commands on flow nodes.
+- Confirm intent before destructive or state-changing operations: deploy, undeploy, execute, delete, refill/backfill, stop, rerun, and similar actions.
+- For historical reruns or backfills, use `cz-cli runs refill <task> --from YYYY-MM-DD --to YYYY-MM-DD`; this is under `runs`, not `task`.
+- For output table JSON flags such as `--output-tables`, pass the JSON array as one shell argument, usually with single quotes.
+
+## Output Handling
+
+- `--format json`: best for parsing.
+- `--format toon`: line-per-field output, useful with `grep` or `head`.
+- `--format table`, `--format csv`, `--format pretty`: human-readable.
+- `--field <name>`: extracts one field as raw text.
+- Paginated list commands usually return page 1; check `ai_message` for next-page hints.
+
+## Command Reference
+
+Read `references/command-reference.md` when you need examples or command coverage beyond these core rules.

Subject: [PATCH 494/521] fix(task): recover --output-tables when shell/agent
 strips quotes or splits JSON

Agent runtimes may strip the surrounding quotes of --output-tables and split the
JSON on internal whitespace, producing stray positional fragments that yargs
rejected with "Unknown command", or an unquoted blob that failed JSON.parse.

- coalesce trailing non-flag fragments back into --output-tables before yargs
- reconstruct output table records from quote-stripped/backslash-escaped blobs,
  returning INVALID_ARGUMENTS only when truly unrecoverable

Implements the existing task-dependency-output-parse spec scenario.

Subject: [PATCH 495/521] fix(cron-adapter): handle hour=* with fixed minute as
 hourly schedule

Expressions like '0 00 * * * ? *' and '0 10 * * * ? *' (every hour at
minute N) were falling through to the 'once daily' branch, producing
NaN in outputCron because parseInt('*') returns NaN.

Add explicit handling: when hour='*' and minute is a fixed value, map
to frequency=2, timeGap=1 (hourly).

toast.show() never defaulted duration, so the zod .default(5000)

it to 5000, and report the copied character count.

Subject: [PATCH 497/521] fix(llm): pin AIGW admin calls to Shanghai for

The /llm-gateway-admin/* routes are only served by the Shanghai
alicloud portal; other alicloud regions return 404 and break key
rotation. Rewrite the admin host to cn-shanghai for those regions
(virtual keys are tenant-global, so the token still authenticates).

- 默认不传 --formatted：直接输出 /open/safe_question_poll 的完整 JSON，
  包含推理过程和最终答案
- 显式传 --formatted：输出格式化后的最终答案，不含推理过程
- --format 全局选项保留原有输出格式控制职责，两者不冲突
- 新增 analytics-agent-session-run.test.ts 覆盖两条路径

验证：
- bun test packages/cz-cli/test/analytics-agent-session-run.test.ts
- UAT: session run 默认输出完整 responses 数组（含推理过程）
- UAT: session run --formatted 只输出最终答案文本

Subject: [PATCH 501/521] fix(task): recover --output-tables when shell/agent
 strips quotes or splits JSON

- Add JOB_TIMEOUT error classification with actionable hints
- Add job cancel and job list subcommands
- Refactor parseParamValueList to handle escaped quotes from shell/agent
- Extract mergeTaskParamValueList for clearer param override logic
- Update skill docs and tests

 ## SQL Rules
 
 - Current default SQL mode is sync: `cz-cli sql "SELECT ..."` waits for results.
-- Use `--async` for large or long-running queries, then inspect with `cz-cli sql status <job-id>` or `cz-cli job status <job-id>`.
+- Use `--async` for large or long-running queries, then inspect with `cz-cli job status <job-id>` or fetch with `cz-cli job result <job-id>`.
 - Write operations always require `--write`, including DDL and DML.
 - If SQL contains quotes, `$`, backticks, backslashes, or newlines, write it to a file and run `cz-cli sql -f <file>` to avoid shell corruption.
-- Use ClickZetta Lakehouse SQL syntax only. Before generating, modifying, validating, explaining, or running non-trivial Lakehouse SQL, load the Lakehouse documentation skill if available.
+- **ClickZetta Lakehouse has its own SQL dialect.** Do NOT assume standard SQL syntax works. Before writing any SQL beyond basic SELECT/INSERT/UPDATE/DELETE, you MUST look up the exact syntax in the lakehouse-doc-en knowledge base. Never guess or trial-and-error SQL syntax — look it up first.
+
+## Job Management
+
+### Show Jobs
+```bash
+cz-cli job list                        # recent 20 jobs
+cz-cli job list --limit 50             # more results
+cz-cli job list --status RUNNING       # filter by status (RUNNING/SUCCEED/FAILED/CANCELLED)
+```
+- Suitable for quick inspection of recent jobs (up to a few hundred).
+- For large-scale job analysis (>10,000 jobs), complex filtering, or aggregation, query `INFORMATION_SCHEMA.JOBS` instead:
+  ```bash
+  cz-cli sql "SELECT job_id, status, start_time, end_time FROM INFORMATION_SCHEMA.JOBS WHERE start_time > '2026-06-01' AND status = 'FAILED' LIMIT 100"
+  ```
+
+### Cancel a Job
+```bash
+cz-cli job cancel <job-id>
+```
+- Cancels a running job immediately via the API.
+
+### Check Job Status / Get Results
+```bash
+cz-cli job status <job-id>       # quick status check
+cz-cli job result <job-id>       # fetch result set (waits if still running)
+cz-cli job profile <job-id>      # execution plan and performance profile
+```

Subject: [PATCH 502/521] fix(task): preserve params in save-config/save-cron
 and fix paramType/collectType

- save-config/save-schedule: read existing params and pass to saveTaskConfig
  to prevent backend from resetting params with auto-parsed defaults (bizdate)
- save-cron: same fix
- create-setup --cron: pass paramValueList to saveTaskConfig
- Fix paramType: always use 'manual' for user-provided params (was 'system')
- Fix collectType: use 1 to match Studio UI (was 0)

Subject: [PATCH 504/521] fix(connection): preserve port and vcluster aliases
 in JDBC URL parsing

parseJdbcUrl dropped the port from the host, so a JDBC string like
jdbc:clickzetta://inst.10.155.2.214:8033/ws produced service=10.155.2.214
and toServiceUrl built http://10.155.2.214/... (port 80) -> ConnectionRefused.

- carry parsed.port into service (host:port), matching toServiceUrl's contract
- accept all three vcluster aliases (vcluster/virtualCluster/virtualcluster)
- map use_http=true to protocol=http

Subject: [PATCH 505/521] fix(profile): use shared JDBC parser in profile
 create (bug-38)

profile create had its own parseJdbcUrl copy that dropped the port and
only recognized the virtualCluster alias, so `profile create --jdbc
jdbc:clickzetta://inst.host:8033/ws?vcluster=DEFAULT` saved service
without :8033 -> requests hit port 80 -> ConnectionRefused, even after
the bug-37 fix (which only touched the connection/ parser).

Delete the duplicate and reuse the already-fixed parseJdbcUrl from
connection/jdbc.ts, so port preservation, all three vcluster aliases,
and use_http=true work in profile create too.

Subject: [PATCH 507/521] feat(cli): support cookie-based authentication for
 profiles

Allow a profile to authenticate via an X-ClickZetta-Token cookie header,
alongside the existing PAT and username/password methods.

- profile create: accept `--header Cookie=...X-ClickZetta-Token=...` as a
  third auth method; skip connection verification on this path since the
  token is supplied directly.
- profile detail: mask the Cookie header value (in addition to pat and
  password) via maskProfileSecrets.
- getExecContext: try the Cookie header first (getCookieToken), parsing the
  JWT payload for userId/accountId/exp and instanceId, and falling back to
  the portal serviceInstanceList API to resolve the instance id by name when
  it is absent; fall back to PAT or username/password when no cookie token
  is present.
- Add profile-cookie-auth tests covering create-time masking, validation,
  and the getExecContext cookie path.

Subject: [PATCH 508/521] fix: handle /api/ path prefix in JDBC URL parsing

When the JDBC URL contains /api/ in the path (e.g. instance.host/api/workspace),
the /api segment is now correctly appended to the service field instead of being
mistakenly treated as the workspace name.

Subject: [PATCH 510/521] feat(task): deterministic offline data-integration
 commands

- Add `task integration setup/show/edit`: build the Studio integration JSON
  deterministically for single-table / multi-table / whole-db offline sync
  (single auto-creates sink table + field mapping; whole-db emits
  dbMirror/dynamicFlag/nameRule).
- Single-table supports --write-mode (OVERWRITE|APPEND|UPSERT), --partitions
  and --param-value-list, mirroring studio-agent integration_task_pre_action /
  edit_integration_sync.
- Remove the agent-driven offline quartet (create-offline-sync,
  offline-sync-schema, save-offline-sync, create-batch-sync) in favor of the
  deterministic path; keep realtime CDC / Kafka commands.
- Fix instanceName (was sc.workspaceName -> sc.instanceName) in kept sync cmds;
  redirect deploy/execute hints to task integration.
- Register task integration in inner-agent prompt (cz-cli-inner.txt) and
  document the offline workflow in the cz-cli skill.

+Notes:
+- `setup` does NOT change field mapping/params on an existing task — use `edit`. `edit` does NOT change source/sink tables — use `setup`.
+- Datasource types are auto-resolved from the datasource name/ID; no need to pass type codes.
+- **`--where` with date/time scheduling params** (e.g. `bizdate`, `$[yyyyMMdd]`, monthly partitions): look up the correct Studio scheduling-parameter syntax first (`cz-cli ai-guide` / docs). Do NOT invent parameter formats.
+- Integration tasks must execute on an **INTEGRATION-type vcluster** — pick one via the vcluster list, not the default/GENERAL vc.

Subject: [PATCH 512/521] fix: display bugs, cron-preview fallback, CDC
 validation, Oracle/SQL Server support (#14)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* refactor: remove redundant code — extract shared helpers, deduplicate logic

CDC prereq check:
- Extract checkCdcPrereqs() as exported function in datasource.ts
- Delete duplicate 95-line implementation from task.ts
- check-cdc command now delegates to shared helper

Duplicate task name check:
- Extract checkDuplicateTaskName() helper in task.ts
- Replace 6 identical 5-line inline blocks with single helper call

Other cleanup:
- Remove redundant targetDsType=1 reassignment in create/save-realtime-sync (was already initialized to 1)
- Fix splitPkExclude: remove TINYINT/SMALLINT which were never in splitPkTypes
- Replace 6 inline new Date().toISOString()... with formatIsoStartOfDay(undefined)

Co-Authored-By: Claude Sonnet 4 (1M context) <noreply@anthropic.com>

* fix: integration test fixes, bug fixes, and help text improvements

Bug fixes:
- formatIsoStartOfDay(undefined) caused infinite recursion — now returns today's date
- flow instances --instance conflicted with global --instance — renamed to --flow-instance
- flow submit published:false — poll condition updated to accept deployStatus=3 (deployed with pending changes)
- save-cron DDL guard: detect CREATE/DROP/ALTER TABLE in task content and block scheduling
- cron-preview next_runs always empty (API returns []) — local fallback via cronNextRuns()
- schedule-info on draft task gave cryptic error — now returns friendly TASK_NOT_DEPLOYED message
- task search treated positional name as subcommand — changed to positional [name]
- save-schedule hanging — caused by formatIsoStartOfDay infinite recursion (same root cause)
- delete-folder non-empty error now lists contained tasks by name
- task create validates name characters before calling API

Help text improvements:
- task flow: describe composite task concept (DAG of nodes) and typical workflow
- All flow subcommands: add context, usage order, and cross-references
- node-save --content/--file: add missing describe fields
- task create --type: fix trailing quote, add FLOW explanation
- task create --folder: mark as demandOption, improve description
- All <task> positionals (24 instances): add "Task name or ID" describe
- create-offline-sync/save-offline-sync: remove agent/MCP jargon
- offline-sync-schema: remove "Agent uses output" phrasing
- create-realtime-sync/create-batch-sync: remove internal type names
- task start --startup-mode: translate Chinese to English
- task start --config: translate Chinese values to English
- task start --engine-type/--blacklist-strategy: replace circular descriptions
- save-schedule --retry-unit/--timeout-unit: clarify m=minutes s=seconds
- task list/list-folders --page/--page-size: add describe fields
- flow node-save-config --cron/--vc/--schema: add describe fields
- Confirmations unified to "Requires -y to proceed."

Chinese aiMessage → English:
- task execute: translate completion message
- task list: translate pagination hint
- task list-folders: translate pagination hint
- task search: remove Chinese truncation suffix

New feature (cron-adapter.ts):
- cronNextRuns(): local Quartz cron calculator supporting named days/months,
  ranges, steps — used as fallback when API returns empty next_runs

* fix: flow bind verify persistence after async write

The bind API returns success before the edge is durably written to DB.
Add post-bind verification: re-query DAG up to 3 times (800ms apart).
If edge is missing, retry the bind call automatically. If still not
confirmed after 3 attempts, return a warning instead of false success.

* fix: Oracle not supported for CDC sync; add dsType whitelist to create/save-realtime-sync

checkCdcPrereqs: Oracle (dsType=25) now returns ok:false with a clear
"not supported" message instead of silently passing through.

create-realtime-sync / save-realtime-sync: validate source dsType
against the supported CDC set before proceeding. Supported sources:
MySQL/TiDB/MariaDB (5,17,18,19,39), PostgreSQL/Greenplum (7,22,40,46,48),
SQL Server (8), DM (26). Unsupported types (including Oracle) are
rejected with UNSUPPORTED_DATASOURCE (exit code 2).

Co-Authored-By: Claude Sonnet 4 (1M context) <noreply@anthropic.com>

* fix: Oracle/SQL Server datasource support — check-cdc, type validation, collectType

datasource check-cdc:
- SQL Server: replace sys.databases/sys.dm_server_services queries
  (inaccessible via getSampleData API) with INFORMATION_SCHEMA.TABLES
  filtered client-side for TABLE_SCHEMA='cdc'. If cdc schema tables
  exist, CDC is enabled and Agent is inferred running.
- Oracle (dsType=25): now returns ok:false with explicit "not supported"
  message instead of silently passing through.

create-realtime-sync / save-realtime-sync:
- Added CDC_SUPPORTED_TYPES whitelist. Supported: MySQL/TiDB/MariaDB,
  PostgreSQL/Greenplum, SQL Server, DM. Oracle and others rejected
  with UNSUPPORTED_DATASOURCE (exit code 2).

save-offline-sync:
- INTEGRATION tasks now use collectType:1 (was 0 from saveTaskContent).
  collectType:0 caused Studio UI to treat the task as a script task,
  leaving field mapping switches in wrong initial state.
- SQL Server: added FlinkX unsupported type check before saving.
  Blocked types: sql_variant, image, binary, varbinary, timestamp.
  text/ntext are supported (map to STRING). Error includes fix hint.

offline-sync-schema:
- SQL Server note updated: lists unsupported types and clarifies
  text/ntext map to STRING.

* fix: task list/downstream/folders display bugs, cron-preview local fallback

- convertTaskFields: pass through already-snake-case fields (task_id,
  task_name, task_type, task_edit_state, path, location, etc.)
- list-folders: map dataFolderName → name, parentFolderId → parent_id
- downstream: map API fields (scheduleTaskId → task_id,
  cycleTaskName → task_name, cycleTaskType → task_type)
- cron-preview: fall back to local cronNextRuns() when API returns empty

* fix: resolveNodeId — accept names via --node-id, warn on duplicates, list available nodes

- resolveNodeArg: new helper that accepts number, numeric string, or node
  name, resolving names through resolveNodeId(). Fixes the case where
  --node-id 'extract' was silently dropped by yargs type:'number'.
- --node-id type changed from 'number' to 'string' in all 4 flow commands
  (node-detail, node-save, node-save-config, remove-node).
- resolveNodeId: filter all matches instead of find() first match.
  When multiple nodes share a name, warns on stderr with --node-id hint.
  When no match, lists all available node names + IDs.
- All call sites simplified from if/else resolveNodeId patterns to a
  single resolveNodeArg() call.

* fix: schedule-info — normalize camelCase API fields to snake_case

- Add SCHEDULE_INFO_FIELDS mapping with 40+ field conversions
- convertScheduleInfoFields(): transform getDetail API response
- Result: cron_expression, task_name, vc_code, etc. now match
  the convention used by task content/save-config commands

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* docs: improve flow param, schedule-info help text clarity

- flow node-save --param: note that re-save replaces ALL params
- flow node-save --flow-param: explain ref=2 inheritance from parent
- schedule-info: note flow tasks use 'task flow instances' instead
- flow submit: mention param persistence and flow run usage
- flow run --param: clarify override targets manual params (ref=0),
  flow-shared params (ref=2) receive flow execution value

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* docs: add workflow guidance and cross-references to help texts

High-impact improvements to reduce call retries and improve task efficiency:

task create: document create→save-content→save-config→deploy workflow
task flow: document full workflow: create FLOW→create-node→node-save→
  node-save-config→bind→submit
task deploy: note prerequisites (must have content + config)
task undeploy: clarify relation to delete (must undeploy before delete)
task delete: clarify draft vs published procedure
task start/stop: cross-reference each other and 'task status'
task list: explain state codes (10=draft, 20=published, 100=offline)
task save-cron: document 7-field cron format with example
datasource list: cross-reference 'datasource test' for connectivity check
datasource test: explain return format and recommend before sync task creation

* docs: improve create-setup help — explain one-step value, add cron examples, clarify params

- Title: explain it combines create+save-content+save-cron+save-config
- Cross-reference 'create-realtime-sync' for CDC tasks
- --type: list concrete values (SQL/PYTHON/SHELL/JDBC/FLOW)
- --folder: tell user how to find IDs ('task folder-tree')
- --content/--file: explain mutual exclusivity, file workflow for multi-line
- --cron: full 7-field format with two examples (daily 09:30, every 5 min)
- --vc: suggest using global --vcluster flag
- --params: explain literal vs system param auto-detection

* docs: improve create-setup help + fix TS type errors

- create-setup: explain one-step value, add cron format examples,
  clarify --content/--file/--folder/--params/--vc descriptions
- Fix 5 fileDescription TS2322 type errors (unknown → string | undefined)

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* docs: fix create-setup --type description — remove FLOW (UI-only, not supported)

UI_ONLY_TYPES: FLOW=500, INTEGRATION=1, REALTIME=14, DT=16,
STREAMING=17, FULL_INCREMENTAL=280, MULTI_REALTIME=281, MULTI_DI=291
— none support one-step create-setup.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* test: add e2e regression tests for PR #14 (display fixes, CDC, help)

29 tests covering:
- task list: verify task_id/task_name/task_type/task_edit_state populated
- task list-folders: verify name field not null
- cron-preview: local fallback returns non-empty next_runs
- datasource check-cdc: MySQL (3 checks), PG (wal check), Oracle (cdc_support=false), SQL Server (cdc+agent), Kafka (ready=true)
- create-realtime-sync dsType whitelist: Kafka → UNSUPPORTED_DATASOURCE, Oracle → error
- task status: edit_state in {draft, published, offline}
- task content: task_id/task_name/schedule_config/studio_url all present
- task search: task_id/task_name/path populated
- task folder-tree: id/name defined
- task stats: tasks.total + run_instances
- task downstream: task_id/task_name mapped from API fields
- schedule-info: snake_case field mapping verified
- flow dag: returns array for FLOW tasks
- help texts: workflow/prerequisites/state codes/cron examples in 10 commands

* fix: cron-preview — correct API field name + default time window

generateInstanceTimeList expects "cron" (not "cronExpress") and requires
scheduleStartTime + scheduleEndTime. The SDK was sending cronExpress
without the time window, causing the API to return empty next_runs.

Changed:
- Field name: cronExpress → cron
- Always send scheduleStartTime (default 00:00) and scheduleEndTime
  (default 23:59) instead of conditionally omitting them

Subject: [PATCH 513/521] fix: create-setup --description, schedule-info
 errors, REALTIME deploy guard (#36)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix: add missing --description option to task create-setup

create-setup handler already uses argv.description when saving the task,
but the yargs option was never declared — invisible in --help and
inconsistent with 'task create' which documents --description.

Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>

* fix: schedule-info friendly error + REALTIME deploy guard (issues 2 & 4)

Issue 2 — schedule-info external call exception:
- FLOW tasks (fileType=500): detected before API call, return friendly note
  pointing to "task flow instances"
- SQL/other tasks deployed without cron: API throws IDE-SYSTEM_EXCEPTION,
  now caught and returns friendly "no active schedule entry" message
  instead of raw TASK_ERROR

Issue 4 — bare REALTIME task deploy fails with "文件参数不匹配":
- fileType=14 (REALTIME) with no content configured now returns
  NO_SYNC_CONFIG error with clear guidance to use "create-stream-sync"
- Configured REALTIME tasks (via create-stream-sync) still deploy normally

Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>

* test: add regression tests for schedule-info errors + REALTIME deploy guard

New tests (describe 15 + 16):

describe "schedule-info friendly errors":
- deployed task without cron → exitCode=0 + friendly note (was: TASK_ERROR)
- FLOW task → exitCode=0 + "use task flow instances" note (was: TASK_ERROR)
- deployed task with cron → still returns full schedule data (no regression)

describe "REALTIME deploy guard":
- bare REALTIME task → NO_SYNC_CONFIG at CLI layer (not backend 文件参数不匹配)
- create-stream-sync configured task → deploys successfully (no regression)

Also fix json() helper to skip leading Warning: lines in output.

Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>

* fix: replace magic length<10 with explicit empty-content check

The length < 10 threshold was checking whether INTEGRATION/REALTIME
fileContent is an empty/placeholder value. Replace with explicit check
for empty string, "null", "[]", "{}".

Subject: [PATCH 514/521] feat(cli): agent-facing error handling, output
 robustness, and /sql flag passthrough

Make the CLI self-correcting and machine-friendly for AI agents and scripts,
and let the interactive /sql prompt command accept flags.

CLI error handling and output (packages/cz-cli):
- Add "did you mean" suggestions for mistyped top-level commands,
  subcommands, and flags, using a length-normalized Damerau-Levenshtein
  matcher (suggest.ts), surfaced in a structured error.did_you_mean field
  plus the human/ai_message channels.
- Run the profile/LLM gate as post-validation yargs middleware so syntax
  errors (unknown command/option, missing argument) surface before
  NO_PROFILE instead of being masked by it.
- Force English yargs locale so built-in messages no longer localize to
  the shell LANG, keeping message/ai_message stable for agents.
- Split the commandGroup fail handler so a mistyped flag is matched against
  flag names (not subcommand names), and route its output through
  renderOutput so --format/--field are honored like the top-level path.
- Reset inherited global --format choices for agent session list/status so
  --help no longer advertises unsupported formats.
- Honor --format/--field in sql --batch mode instead of always raw JSON.
- Emit a structured result envelope from update when machine-bound
  (explicit --format or non-TTY), keeping interactive output human-only.
- Add next-step ai_message guidance to async commands that return an id
  (job status/cancel, runs stop/rerun, task flow run, analytics-agent
  session create) so agents know how to poll or continue.
- Add suggest and robustness test suites; wire them into test:unit/test:all.

Interactive TUI (packages/opencode):
- Support flag passthrough in the /sql prompt command.

Subject: [PATCH 515/521] fix(cli): correct ai_message guidance and honor
 invocation args in subcommand errors

Review fixes on top of the agent-robustness work:

- command-group: resolve --format/--field from the invocation args (stashed on
  the yargs instance by createCli) instead of process.argv. On the same-process
  execute() path, process.argv belongs to the host (TUI/MCP), so usage errors
  in subcommand groups previously ignored the caller's --format/--field. Adds a
  same-process regression test that fails against the old behavior.

- job status: when a job is still RUNNING, point agents at the synchronous
  `job result` (which blocks until completion) and clarify that status is a
  point-in-time snapshot, instead of instructing them to hand-roll a status
  poll loop.

- task downstream: fix ai_message referencing the non-existent
  `cz-cli task upstream`; the command for a task's upstream dependencies is
  `cz-cli task deps`.

  (previously hardcoded null) via SaveFlowNodeContentParams
- task flow node-save: add --output-param (declares $[output] producer) and
  --input-param key=upstreamNodeName (resolves upstream node name to
  dependencyId via flow DAG, builds ref=0 $[output] consumer entry)
- add flow-params SDK tests covering both param chains

* feat: support merge task workflow

Add MERGE task contracts, save-merge command, deploy guard, SDK payload fields, specs, tests, and agent docs.

+name: openspec-sync-specs
+description: Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.4.1"
+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Resolve change context**
+
+   Run:
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+   If status reports `actionContext.mode: "workspace-planning"`, explain that workspace spec sync is not supported in this slice and STOP. Do not fall back to repo-local paths or edit linked repos.
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+4. **For each delta spec, apply changes to main specs**
+
+   For each repo-local capability delta spec path returned by the CLI:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+5. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+- For flow node params, use `cz-cli task flow node-save`: `--param key=value` for manual defaults, `--flow-param key` for values inherited from parent flow execution params, `--output-param key` to declare `$[output]`, and `--input-param key=upstreamNodeName` to consume an upstream node output. Bind the upstream dependency first so the upstream node can resolve from the DAG.
 - Confirm intent before destructive or state-changing operations: deploy, undeploy, execute, delete, refill/backfill, stop, rerun, and similar actions.
 - For historical reruns or backfills, use `cz-cli runs refill <task> --from YYYY-MM-DD --to YYYY-MM-DD`; this is under `runs`, not `task`.
 - For output table JSON flags such as `--output-tables`, pass the JSON array as one shell argument, usually with single quotes.

-For task params, `save-content` supports `--params '{"key":"val","dt":"bizdate","yd":"$[yyyy-MM-dd,-1d]"}'`. System params such as `bizdate`, `sys_plan_day`, and `sys_biz_datetime` are auto-detected.

+
+`save-content --params` stores params while saving content. `save-config --param key=value` merges overrides with existing task params and preserves script content. System params such as `bizdate`, `sys_plan_day`, and `sys_biz_datetime` are auto-detected for JSON `--params` values.

+
+`--output-param key` declares an output value as `$[output]`. `--input-param key=upstreamNodeName` resolves the upstream node id from the flow DAG, so create/bind nodes before using it. `--flow-param key` marks a child node param as inherited from the parent flow execution params (`ref=2`).

+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+   **Workspace guard:** If status JSON reports `actionContext.mode: "workspace-planning"` and `allowedEditRoots` is empty, explain that full workspace apply is not supported in this slice. Treat linked repos and folders as read-only context, ask the user to select an affected area through an explicit implementation workflow, and STOP before editing files.
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! Ready to archive this change.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   If status reports `actionContext.mode: "workspace-planning"`, explain that workspace archive is not supported in this slice and STOP. Do not move workspace changes into repo-local archives or edit linked repos.
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
+   ```bash
+   mkdir -p "<planningHome.changesDir>/archive"
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move `changeRoot` to the archive directory
+
+   ```bash
+   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.4.1"
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Resolve and read existing artifacts for context**
+   - Run `openspec status --change "<name>" --json`.
+   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
+   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---

+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change proposal
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+Propose a new change - create the change and generate all artifacts in one step.
+
+I'll create a change with artifacts:
+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+  version: "1.0"

+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Resolve change context**
+
+   Run:
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+   If status reports `actionContext.mode: "workspace-planning"`, explain that workspace spec sync is not supported in this slice and STOP. Do not fall back to repo-local paths or edit linked repos.
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+4. **For each delta spec, apply changes to main specs**
+
+   For each repo-local capability delta spec path returned by the CLI:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+5. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+# Studio Workspace Parameter Lifecycle 交接
+
+更新时间：2026-06-28 15:00 Asia/Shanghai
+
+## 背景
+
+这次改动来自 `dataworks-spec` 的 ADF -> Lakehouse Studio 迁移需求：ADF factory/global parameters 需要映射到 Studio workspace parameters。由于 `workspace-param` 是 `cz-cli` 自己暴露的 Studio 命令面，已经在本仓库单独落 OpenSpec，不再只记录在 `dataworks-spec` 迁移 change 中。
+
+OpenSpec change：
+
+```text
+openspec/changes/studio-workspace-parameter-lifecycle
+```
+
+## 已实现范围
+
+- SDK：`packages/clickzetta-sdk/src/studio/workspace-params.ts`
+  - `listWorkspaceParams`
+  - `addWorkspaceParam`
+  - `updateWorkspaceParam`
+  - `enableWorkspaceParam`
+  - `disableWorkspaceParam`
+  - `deleteWorkspaceParam`
+- CLI：`packages/cz-cli/src/commands/workspace-param.ts`
+  - `cz-cli workspace-param list`
+  - `cz-cli workspace-param add`
+  - `cz-cli workspace-param update`
+  - `cz-cli workspace-param enable`
+  - `cz-cli workspace-param disable`
+  - `cz-cli workspace-param delete`
+- 注册入口：
+  - `packages/cz-cli/src/register-commands.ts`
+  - `packages/clickzetta-sdk/src/index.ts`
+- 测试：
+  - `packages/clickzetta-sdk/test/workspace-params.test.ts`
+  - `packages/cz-cli/test/e2e-help/core-cases.ts`
+
+## 真实接口契约
+
+- `list` -> `/ide-admin/v1/workspaceParams/list`
+  - body: `{ projectId, pageIndex, pageSize }`
+- `add` -> `/ide-admin/v1/workspaceParams/add`
+  - body: `{ projectId, paramKey, paramValue, sourceType, encrypt }`
+- `update` -> `/ide-admin/v1/workspaceParams/update`
+  - body: `{ projectId, id, paramKey, paramValue, sourceType, encrypt }`
+- `enable` -> `/ide-admin/v1/workspaceParams/publish`
+  - body: `{ projectId, id }`
+- `disable` -> `/ide-admin/v1/workspaceParams/offline`
+  - body: `{ projectId, paramIds: [id] }`
+- `delete` -> `/ide-admin/v1/workspaceParams/delete`
+  - body: `{ projectId, paramIds: [id] }`
+
+实测注意：`offline` 用 `{ id }` 会失败，服务端返回 `paramIds不能为空`。不要改回单个 `id`。
+
+## 已验证
+
+```shell
+cd /Users/zhanglin/IdeaProjects/cz-cli/packages/clickzetta-sdk
+bun test test/workspace-params.test.ts
+```
+
+结果：6 pass / 0 fail。
+
+```shell
+cd /Users/zhanglin/IdeaProjects/cz-cli/packages/cz-cli
+bun test ./test/e2e-help.ts
+```
+
+结果：97 help cases passed / 0 failed。
+
+```shell
+cd /Users/zhanglin/IdeaProjects/cz-cli
+openspec validate studio-workspace-parameter-lifecycle --strict
+openspec instructions apply --change studio-workspace-parameter-lifecycle --json
+```
+
+结果：validate 通过；tasks 15/15 complete，`state=all_done`。
+
+真实 UAT smoke：
+
+- profile：`uat_new`
+- 操作链路：`add -> list -> update -> enable -> disable -> delete -> final list`
+- 结果：全部成功，最终列表确认临时参数已删除。
+- 不要在文件中保存 token、cookie、session id 或临时 smoke key。
+
+## 接手注意
+
+- `workspace-param` 是 Studio workspace parameter 命令，不是 Lakehouse `workspace` 命令的子命令。
+- `--project-id` 默认来自 `getStudioContext()` 的当前 workspace project，也允许显式覆盖。
+- `update/enable/disable/delete` 都要求正数 `--id`。
+- `dataworks-spec` 的迁移 writer 自动 upsert 只应调用 `workspace-param list/add`；生命周期操作必须由用户显式调用。
+- 当前 cz-cli 工作区有大量既有 dirty 文件；本次 workspace-param 相关文件以上述列表为准。

+## Context
+
+Studio workspace 参数是 Studio 项目级公共参数，不等同于 Lakehouse workspace 切换命令。ADF 迁移会把工厂全局参数映射到 Studio workspace 参数；同时用户也需要独立运维这些参数的启用、停用、更新和删除。
+
+当前 `cz-cli` 已有 Studio profile/context 解析能力，能够从 profile 得到 token、实例、workspace、projectId 等调用 Studio API 所需上下文。workspace 参数接口使用 `projectId` 而不是 workspace 名称作为主定位字段，因此命令必须明确处理 `projectId` 默认值和显式覆盖。
+
+## Goals / Non-Goals
+
+**Goals:**
+- 在 SDK 中封装 Studio workspace 参数的 list/add/update/publish/offline/delete API。
+- 暴露 `cz-cli workspace-param` 顶层命令族，支持完整生命周期操作。
+- 将 `workspace-param` 纳入顶层路由和 help coverage，避免隐藏命令或未测 help 漂移。
+- 保留真实接口请求体差异，尤其是停用和删除使用 `paramIds` 数组。
+- 通过单元测试、help 测试和真实 profile smoke 验证命令可用。
+
+**Non-Goals:**
+- 不在该命令里实现批量更新、批量启停或批量删除。
+- 不改变 `workspace` 命令族语义；`workspace` 仍表示 Lakehouse workspace 切换和查看。
+- 不在测试或 OpenSpec 中固化用户 token、cookie、session id 或一次性 smoke 参数 key。
+- 不把 ADF 迁移 writer 的自动 upsert 流程扩展为自动启停删；迁移 writer 只需要 list/add，生命周期操作由用户显式执行。
+
+## Decisions
+
+1. 新增独立顶层命令 `workspace-param`，不挂在 `workspace` 下。
+   - `workspace` 已用于 Lakehouse workspace 管理；Studio workspace 参数是项目级配置对象，混入 `workspace` 会造成命令语义歧义。
+   - 顶层命令也便于迁移 writer 通过 `cz-cli workspace-param list/add` 调用。
+
+2. SDK 使用薄封装，不隐藏 Studio API 字段。
+   - `listWorkspaceParams` 请求 `/ide-admin/v1/workspaceParams/list`，请求体包含 `projectId`、`pageIndex`、`pageSize`。
+   - `addWorkspaceParam` 请求 `/add`，请求体包含 `projectId`、`paramKey`、`paramValue`、`sourceType`、`encrypt`。
+   - `updateWorkspaceParam` 请求 `/update`，请求体包含 `projectId`、`id`、`paramKey`、`paramValue`、`sourceType`、`encrypt`。
+   - `enableWorkspaceParam` 请求 `/publish`，请求体包含 `projectId`、`id`。
+   - `disableWorkspaceParam` 请求 `/offline`，请求体包含 `projectId`、`paramIds: [id]`。
+   - `deleteWorkspaceParam` 请求 `/delete`，请求体包含 `projectId`、`paramIds: [id]`。
+
+3. CLI 默认从 Studio context 取 `projectId`，但所有子命令都允许 `--project-id` 覆盖。
+   - 默认值满足日常 profile 使用。
+   - 显式 `--project-id` 满足多项目或自动化场景。
+   - `--project-id` 和 `--id` 必须校验为正数，避免发送无意义请求。
+
+4. 状态变更命令必须由用户显式调用。
+   - `enable`、`disable`、`delete` 不作为 `add` 或 `update` 的隐式副作用。
+   - `delete` 暂不增加额外交互确认，因为 CLI 命令本身就是明确的 destructive intent；自动化场景需要非交互可用。
+
+5. 输出保持通用 `success/error` 格式。
+   - `--format json` 直接返回 Studio API 的 `data`，便于脚本消费。
+   - 错误码按子命令区分，例如 `WORKSPACE_PARAM_UPDATE_FAILED`，便于自动化定位失败阶段。
+
+## Risks / Trade-offs
+
+- Studio API 请求体不一致导致实现猜错 -> 用 SDK request-construction 测试固定每个端点请求体，并用真实 profile smoke 覆盖 add/update/enable/disable/delete。
+- `projectId` 来源不清晰 -> 命令默认使用 `getStudioContext` 中的当前 workspace project，同时支持 `--project-id` 覆盖。
+- 真实 smoke 可能污染用户项目 -> smoke 必须创建唯一临时 key，成功或失败都尝试停用和删除。
+- 用户粘贴 token 或一次性参数 key 可能被误写入仓库 -> 测试和文档只记录接口字段与行为，不保存 token、cookie、session id 或 smoke key。
+
+## Migration Plan
+
+1. 添加 SDK 封装和请求构造测试。
+2. 添加 `workspace-param` 命令处理、顶层注册和 help coverage。
+3. 用本地源码 CLI 通过配置 profile 做真实生命周期 smoke。
+4. 保留 `dataworks-spec` 迁移 writer 中的 list/add 调用，但把完整生命周期契约以本 change 为准。
+
+Rollback 方式是移除 `registerWorkspaceParamCommand` 注册和对应 SDK 导出；已创建的 Studio workspace 参数不受 CLI 代码回滚影响。

+## Why
+
+Studio workspace 参数已经成为 ADF 迁移和手工运维都需要的公共能力。此前相关约束只记录在 `dataworks-spec` 的迁移 change 中，但 `workspace-param` 是 `cz-cli` 自己暴露的 Studio 命令面，必须在本仓库 OpenSpec 中落地，避免后续命令、SDK 或 help 覆盖漂移。
+
+## What Changes
+
+- 新增 `cz-cli workspace-param` 顶层命令族，覆盖 Studio workspace 参数的 `list`、`add`、`update`、`enable`、`disable` 和 `delete`。
+- 新增 SDK 封装，调用 Studio workspace 参数接口：`/list`、`/add`、`/update`、`/publish`、`/offline`、`/delete`。
+- 命令默认从当前 Studio workspace 上下文解析 `projectId`，同时允许用户显式传入 `--project-id`。
+- `update` 必须携带参数 id、key、value、source type 和 encrypt；`enable`、`disable`、`delete` 必须按参数 id 操作。
+- `disable` 和 `delete` 使用 Studio 实测需要的 `paramIds: [id]` 请求体，不使用单个 `id` 字段。
+- 将 `workspace-param` 纳入 CLI 顶层路由和 help coverage，确保公开命令可发现且 help 不需要真实 profile。
+
+## Capabilities
+
+### New Capabilities
+- `studio-workspace-parameters`: Studio workspace 参数 SDK 和 CLI 生命周期命令，覆盖请求体、project id 解析、输出、错误和真实 smoke 验证要求。
+
+### Modified Capabilities
+- `cli-command-routing`: 新增 `workspace-param` 顶层命令应被 CLI 路由识别，并出现在 `cz-cli --help` 中。
+- `help-coverage`: 新增 `workspace-param` 命令族的 help 覆盖要求。
+
+## Impact
+
+- `packages/clickzetta-sdk/src/studio/workspace-params.ts`: 新增 Studio workspace 参数 API 封装。
+- `packages/clickzetta-sdk/src/index.ts`: 导出 workspace 参数 SDK。
+- `packages/cz-cli/src/commands/workspace-param.ts`: 新增 CLI 命令族。
+- `packages/cz-cli/src/register-commands.ts`: 注册顶层命令。
+- `packages/clickzetta-sdk/test/workspace-params.test.ts`: 覆盖 SDK 请求构造。
+- `packages/cz-cli/test/e2e-help/core-cases.ts`: 覆盖 help 可发现性。
+- Studio API: `/ide-admin/v1/workspaceParams/list`、`/add`、`/update`、`/publish`、`/offline`、`/delete`。

 **SQL is async by default**. Use `--sync` for SELECT when you need data immediately.
 **Write operations ALWAYS require `--write` flag** — this includes ALL DDL (CREATE, ALTER, DROP, CREATE DYNAMIC TABLE, CREATE MATERIALIZED VIEW) and ALL DML (INSERT, UPDATE, DELETE, MERGE INTO, COPY INTO). Without `--write`, the command will be rejected. Always add it proactively.

+**Always pass `--type` when creating tasks** (SQL/PYTHON/SHELL/SPARK/FLOW/MERGE).
 **Flow tasks use `task flow *` commands exclusively** — never use `task save-content` or `task deploy` on flow nodes.
+**Merge tasks**: create with `task create --type MERGE`, then configure with `task save-merge <task> --dependency <upstream> --status SUCCESS --status FAILED`. Add `--status SKIPPED` only when the upstream is an if/condition task.
+**Task params**: for standalone tasks, use `task save-content --params '{"k":"v"}'` when saving content, or `task save-config --param k=v` to merge/update params while preserving content. For flow nodes, use `task flow node-save --param`, `--flow-param`, `--output-param`, and `--input-param`.
+**Flow node input/output params**: declare upstream outputs with `--output-param key`, bind upstream/downstream, then consume them with downstream `--input-param key=upstreamNodeName`. `--input-param` resolves the upstream node ID from the flow DAG.
 **Paginated results**: `list` commands return page 1 only. Check `ai_message` in response for next-page hints.
 **State-changing operations** (deploy/undeploy/execute/delete/refill): confirm intent with user first.
 **Multi-environment**: use `--profile <name>` to target a specific environment.

+本需求 MUST 按以下场景执行。
+
+当 profile 的 `header.Cookie` 中携带 `X-ClickZetta-Token` 时，该 token 即为完整的 wire 认证凭证。运行时 MUST 在换取 token 前优先识别 cookie token，并直接将其用作 `AuthToken`，而不是回退到 `loginSingle` 登录。此认证方式 MUST 同时覆盖 SQL 执行路径与 studio / analytics-agent / gateway 等经由 `getStudioContext` / `getGatewayContext` 的命令，行为在各路径间保持一致。

+
+- **WHEN** profile 只配置了 `header.Cookie`（含 `X-ClickZetta-Token`），没有 `pat` 也没有 `username/password`，用户执行 `cz-cli analysis agent ...` 或其它 studio/gateway 命令
+- **THEN** 运行时从 cookie 中解析出 token 并直接作为认证凭证，不调用 `/clickzetta-portal/user/loginSingle`

Subject: [PATCH 521/521] feat(profile): default profile list to table format

profile list previously defaulted to raw JSON, which is hard to read
interactively. When --format is not explicitly provided, default to the
table format for human readability. Explicit --format (json/pretty/etc.)
and scripted/programmatic execute() callers are unaffected.
