Peter Rozsa created IMPALA-13205:
------------------------------------
Summary: Use separate merge query when there are no delete or
update cases listed
Key: IMPALA-13205
URL: https://issues.apache.org/jira/browse/IMPALA-13205
Project: IMPALA
Issue Type: Sub-task
Reporter: Peter Rozsa
Assignee: Peter Rozsa
If a MERGE statement lists no WHEN MATCHED THEN DELETE or WHEN MATCHED THEN
UPDATE clause, the merge query should not contain the position values of the
target table. It should be handled in analyze time and requires a different
evaluation at the Iceberg Merge node at the execution layer.
