feat: DB models (User, EventLog, Bet index) + Soroban RPC event subscription - #1163
Merged
Conversation
- Add User model to Prisma schema with address as primary key - Stellar address format validation regex (G...56 chars) - createdAt and updatedAt timestamps Task 1: Implement the DB table/migration for UserModel
- Add User model: address PK, createdAt, updatedAt - Add EventLog model: idempotent ingestion via @@unique(txHash, eventType), nullable processedAt with index for unprocessed queries - Add @@index([marketId, bettor]) on Bet for fast lookups - Migration SQL for all three schema changes Tasks 1-3: DB table/migration for UserModel, BetModel, EventLogModel
- Bootstraps the indexer by calling startIndexer() - Graceful crash handling with exit code 1 - Requires STELLAR_RPC_URL, MARKET_FACTORY_CONTRACT_ID, and DATABASE_URL Task 4 (part 1): Indexer entry point
… processing
- Subscribe to ALL contract events (no contractIds filter) so dynamically
deployed Market contract events are never missed across restarts
- Write raw events to EventLog table BEFORE downstream processing via
persistRawEvents() with idempotent upsert on (txHash, eventType)
- Mark events as processed after successful downstream processing via
markEventsProcessed() using nullable processedAt index
- Exponential backoff reconnection on RPC disconnect (existing behavior)
- Route known events through switch/case handlers, log warnings for unknowns
Task 4: Subscribe to Soroban RPC events for all three contracts
and persist raw events
