Yun Gao commented on FLINK-30238:
---------------------------------
Hi [~agg_neha07] I think the change of intermediate savepoint (namely the ones
not triggered by stop-with-savepoint) comes from the modification to skip
savepoint for recovery:
[https://cwiki.apache.org/confluence/display/FLINK/FLIP-193%3A+Snapshots+ownership,]
which is merged in 1.15. With this modification the intermediate savepoint
will only do snapshots and will not commit side-effect.
May I have a double confirmation about the detailed issue that the change
caused issues for the delta sink pipeline?

> Key: FLINK-30238
> URL: https://issues.apache.org/jira/browse/FLINK-30238
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Common
> Affects Versions: 1.17.0, 1.15.3, 1.16.1
> Reporter: Fabian Paul
> Priority: Critical
>
> During stop-with-savepoint the committer only commits the pending
> committables on notifyCheckpointComplete.
> This has several downsides.
> * Last committableSummary has checkpoint id LONG.MAX and is never cleared
> from the state leading to that stop-with-savepoint does not work when the
> pipeline recovers from a savepoint
> * While the committables are committed during stop-with-savepoint they are
> not forwarded to post-commit topology, potentially losing data and preventing
> to close open transactions.
