Resolution: Fixed
> 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
> Priority: Major
> 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.

> POC: https://github.com/apache/flink-table-store/pull/590
