And as CDC data synchronization, I think we need to support schema evolution(DDL) as a feature, and I want to hear from you all how you think it can be implemented in SeaTunnel. # Motivation - Support read database ddl sql (mysql/oracle/...) - Support ddl sync to any sink（Standardized parse ddl to event） - Support pause and resume ddl at any time - Support automatic processing of old data and new data switche # Overall Design  - Depends on checkpoint to push change signals: reader -> writer -> committer ### Task list [x] https://github.com/apache/seatunnel/pull/5125 ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! -- This is an automated message from the Apache Git Service.
