-----------------------------------
Summary: Unified Sink committer does not clean up state on final
savepoint
Key: FLINK-30238
URL: https://issues.apache.org/jira/browse/FLINK-30238
Project: Flink
Issue Type: Bug
Components: Connectors / Common
Affects Versions: 1.15.3, 1.17.0, 1.16.1
Reporter: Fabian Paul
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.
