Shuai Xu commented on FLINK-34380:
----------------------------------
+1 for the desciption by [~xuyangzhong].
Rowkind issue should be addressed in a new thread.
Ordering issue:
- Retract sink → out-of-order / transient rows have no bad effect; the stream
still converges to the correct
result.
- Upsert sink → a SinkUpsertMaterializer is inserted automatically to reconcile
the changelog by primary key.
- Append-only sink → rejected by the planner at compile time.
