[jira] [Created] (FLINK-38362) Reduce the time cost in checkpoint when writing many tables to StarRocks sink

Yanquan Lv created FLINK-38362:
----------------------------------

             Summary: Reduce the time cost in checkpoint when writing many tables to StarRocks sink
                 Key: FLINK-38362
                 URL: https://issues.apache.org/jira/browse/FLINK-38362
             Project: Flink
          Issue Type: Improvement
          Components: Flink CDC
    Affects Versions: cdc-3.4.0
            Reporter: Yanquan Lv


At each checkpoint, we need to perform flush/commit operations on all written tables. 
If a large number of tables are involved, parallel processing can be significantly more efficient than serial processing.
