Hi all, I created some issues regarding to the discussion above,
https://github.com/ververica/flink-cdc-connectors/issues/1140 https://github.com/ververica/flink-cdc-connectors/issues/1138 https://github.com/ververica/flink-cdc-connectors/issues/1135 Maybe we can discuss them under these specific issues, thanks a lot !
