> Support TO_CHANGELOG: retract stream -> retract stream with set semantics
> -------------------------------------------------------------------------

> Key: FLINK-39614
> URL: https://issues.apache.org/jira/browse/FLINK-39614

> Issue Type: Sub-task

> TO_CHANGELOG is currently locked to row semantics. The conditional
> SET_SEMANTIC_TABLE trait declared in FLINK-39392 is never honored at the
> type-strategy or runtime level, so calling TO_CHANGELOG(input => TABLE t
> PARTITION BY k) either fails or duplicates the partition key column in the
> output.
> This ticket adds support for set semantics for retract: when PARTITION BY is
> provided, the framework prepends the partition key column(s), and the
> function emits [op, ...non-partition input fields]
