Au-Miner opened a new pull request, #28198:
URL: https://github.com/apache/flink/pull/28198
## What is the purpose of the change
Fix `DynamicTableSink.Context#getTargetColumns` for row-level UPDATE so it
contains all columns delivered to the sink, instead of only the columns from
the SET clause.
Due to the dependency on the pre-PR FLINK-36735, it is set to draft PR.
## Brief change log
- Change `DynamicSinkUtils#convertSinkToRel` to apply target columns after
the UPDATE rewrite, using the required physical columns returned by
`convertUpdate`.
- Add target-column capture support in `TestUpdateDeleteTableFactory` for
both sink ability application and runtime sink context.
## Verifying this change
Updated `RowLevelUpdateTest` plan expectations and `UpdateTableITCase`
assertions to verify full-row, partial required-column, and disjoint
required/updated-column UPDATE cases expose the correct target columns.
