> Currently, the logic in FlinkChangelogModeInferenceProgram for enabling upsert materialize does not distinguish between retract and upsert. Thus, SinkUpsertMaterializer is added for retract sinks. The resulting changelog is incorrect as it misses -U. Retract is flexible enough to simply be passed to the sink without further changes.
