Till Rohrmann commented on FLINK-23317:
---------------------------------------
I am not sure whether this improvement justifies the required work. Given that
we haven't received immediate demand, I would postpone this feature for later.
> Only keep the latest checkpoint in CompletedCheckpointStore

> URL: https://issues.apache.org/jira/browse/FLINK-23317
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Reporter: David Morávek
> Assignee: Nicolaus Weidner
> Priority: Minor
>
> Issue based on the discussion from FLINK-22483
> We can lower the memory footprint of CompletedCheckpointStore by keeping only
> the latest checkpoint / savepoint, that will be used for recovery. We need to
> respect `preferCheckpoint`, but the sentiment of this stays the same.
