URL: https://github.com/apache/doris/pull/59896
Add support for `unique_key_update_mode` property in routine load to enable
flexible partial columns update. This allows different rows in the same batch
to update different columns, unlike fixed partial update where all rows must
update the same columns.
Changes:
- Add `unique_key_update_mode` property to CreateRoutineLoadInfo with
values: UPSERT (default), UPDATE_FIXED_COLUMNS, UPDATE_FLEXIBLE_COLUMNS
- Add validation for flexible partial update constraints (JSON format only,
no jsonpaths, no fuzzy_parse, no COLUMNS clause, no WHERE clause, table must
have skip_bitmap column enabled)
- Update RoutineLoadJob to persist and restore the update mode
- Update KafkaRoutineLoadJob to pass update mode to task info
- Support ALTER ROUTINE LOAD to change unique_key_update_mode
- Add regression tests covering basic usage and error cases
- Fix HashMap ordering issue in gsonPostProcess for backward compatibility
- Add validation when ALTER changes mode to UPDATE_FLEXIBLE_COLUMNS
- Add comprehensive ALTER test cases for flexible partial update validation
