[jira] [Created] (FLINK-40102) MySQL CDC Source: Support batch emitting CreateTableEvents to reduce schema coordination overhead

--------------------------------

             Summary: MySQL CDC Source: Support batch emitting CreateTableEvents to reduce schema coordination overhead
                 Key: FLINK-40102
                 URL: https://issues.apache.org/jira/browse/FLINK-40102
             Project: Flink
          Issue Type: New Feature
          Components: Flink CDC
            Reporter: ericzeng


In the MySQL CDC pipeline connector's `initial` startup mode, each split lazily loads and emits CreateTableEvents per table during the snapshot phase. When dealing with thousands of tables, this per-table coordination introduces significant schema coordination overhead, prolonging snapshot duration.
