Change subject: IMPALA-13362: Implement WHEN NOT MATCHED BY SOURCE syntax for MERGE statement ...................................................................... IMPALA-13362: Implement WHEN NOT MATCHED BY SOURCE syntax for MERGE statement This change adds support for a new MERGE clause that covers the condition when the source statements rows do not match the target tables rows. Example: MERGE INTO target t using source s on t.id = s.id WHEN NOT MATCHED BY SOURCE THEN UPDATE set t.column = "a"; This change also adds support to use WHEN NOT MATCHED BY TARGET explicitly, this is equivalent to WHEN NOT MATCHED. Tests: - Parser tests for the new language elements. - Analyzer and planner test for WHEN NOT MATCHED BY SOURCE/TARGET clauses. - E2E tests for WHEN NOT MATCHED BY SOURCE clause.
