[jira] [Created] (FLINK-37509) Increment scan source no need to buffer data when enable skipping backfill.

Hongshun Wang created FLINK-37509:
-------------------------------------

             Summary: Increment scan source no need to buffer data when enable skipping backfill.
                 Key: FLINK-37509
                 URL: https://issues.apache.org/jira/browse/FLINK-37509
             Project: Flink
          Issue Type: Improvement
          Components: Flink CDC
    Affects Versions: cdc-3.3.0
            Reporter: Hongshun Wang
             Fix For: cdc-3.4.0


Currenly, if enable skipping backfill, only provide at-least-once mechanism, thus no need to buffer snapshot data. Emit the snapshot data directly, if some wrong, will resend it.
