 Review comment:
   This is the INSERT branch of a merge statement. Bucketing key (`clustered by (a)`) is same that is present in the right outer join hence it seems fine.
   ```explain merge into acidTbl as t using nonAcidOrcTbl s ON t.a = s.a 
   WHEN MATCHED AND s.a > 8 THEN DELETE
   WHEN MATCHED THEN UPDATE SET b = 7
   WHEN NOT MATCHED THEN INSERT VALUES(s.a, s.b)```
