[jira] [Created] (IMPALA-13205) Use separate merge query when there are no delete or update cases listed

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.
