> Hi @VinaySagarGonabavi, thanks for your contribution. Actually Transform operator used to be stateful until #4056. The idea is transform rules itself is deterministic and making it a pure mapping node makes more sense. > > As for the problem mentioned above, Transform operator should emit `CreateTableEvent` with newly transformed schema after restarting from checkpoint. Should the `SchemaOperator` and `SchemaCoordinator` (they're stateful) take the responsibility of handling these changes and emit correct schema change events to downstream? @yuxiqian Thanks for looking into the PR, and explaining the design direction. I agree with the approach suggested. There is a follow up PR (v2) with handling in `SchemaCoordinator` and `SchemaOperator` https://github.com/apache/flink-cdc/pull/4299 .
