 Run optimzation:
+```
 spark.sql("OPTIMIZE atm").show(truncate=False)
+```
 
 Check files you can delete:
+```
 spark.sql("vacuum atm RETAIN 0 HOURS DRY RUN")
+```
 
 Delete optimized and consolidated files:
+```
 spark.sql("vacuum atm RETAIN 0 HOURS")
+```
 
 and check details of your table:
+```
 spark.sql("describe detail atm").show(truncate=False)
