             Summary: Support append only mode for MySQL CDC connector
                 Key: FLINK-36684
                 URL: https://issues.apache.org/jira/browse/FLINK-36684
             Project: Flink
          Issue Type: Improvement
          Components: Flink CDC
    Affects Versions: cdc-3.3.0, cdc-3.2.1
            Reporter: Runkang He


In real user scenario, some users need to save all upstream changelogs as 
append only messages in downstream database. Users can delete some messsages 
later in downstream based on 'row_kind' metadata, or just save all messsages 
for auditing.
 
In this scenario, we need to support converting all kind of changelogs to 
append only messages, and use metadata 'row_kind' to represent the original 
changelog kind.
