> This pr i edit for last month ,u can cc .https://github.com/ThorneANN/flink-cdc/tree/serrizer-only-tablels During binlog parsing, filtering out the parsing of fields for irrelevant tables in TableMapEventMetadata is indeed a great optimization opportunity. However, doing only that is not enough: if we don’t also apply filtering during the subsequent parsing of insert/update/delete row change events, parsing can still fail because the metadata column types are actually needed there. Therefore, we can first consider merging the parsing optimization in the current PR, and then continue optimizing TableMapEventMetadata afterward. -- This is an automated message from the Apache Git Service.
