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

             Summary: Wait compaction only when table set deletion-vectors.enabled to true in PaimonWriter
                 Key: FLINK-37577
                 URL: https://issues.apache.org/jira/browse/FLINK-37577
             Project: Flink
          Issue Type: Improvement
          Components: Flink CDC
    Affects Versions: cdc-3.3.0
            Reporter: Yanquan Lv


In https://issues.apache.org/jira/browse/FLINK-36790 , we enforce waitCompaction in PaimonWriter to avoid DeletionVectorsMaintainer CME problem, however, this will lead to a long checkpoint time even if Paimon table don't enable deletion-vector.

The end-to-end checkpoint cost time can be seen in here.
