[jira] [Created] (FLINK-31391) Introduce lookup changelog producer

Jingsong Lee created FLINK-31391:
------------------------------------

             Summary: Introduce lookup changelog producer
                 Key: FLINK-31391
                 URL: https://issues.apache.org/jira/browse/FLINK-31391
             Project: Flink
          Issue Type: New Feature
          Components: Table Store
            Reporter: Jingsong Lee
            Assignee: Jingsong Lee
             Fix For: table-store-0.4.0


Currently, only full-compaction can produce changelog, some merge-engine must have changelog producing, for example, partial-update and aggregation. But full-compaction is very heavy, write amplification is big huge...

We should introduce a new changelog producer, supports lower latency to produce changelog.
