### Search before asking - [X] I had searched in the [feature](https://github.com/apache/incubator-seatunnel/issues?q=is%3Aissue+label%3A%22Feature%22) and found no similar feature requirement. ### Description When I use ST for full updates and the sink side is JDBC, I may need to clear the table data on the sink side first and then perform full inserts. However, I have not seen any pre synchronization operations in the official documents. How can I solve this problem, except for manual cleaning.  ### Usage Scenario _No response_ ### Related issues _No response_ ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
