-------------------------------------------------------------------
I don't quite understand why this would be required if you have FLINK-24113.
If you manually shut down the cluster via the REST API, then after a
stop-with-savepoint you can just wait for the job to terminate, then query the
savepoint location via the checkpoints endpoint, then shut it down.
Irrespective of whether it generally makes sense to make this parameter
configurable, it doesn't seem required for your use-case.

> Key: FLINK-24114
> URL: https://issues.apache.org/jira/browse/FLINK-24114
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.15.0
> Reporter: Robert Metzger
> Priority: Major
>
> Currently, it can happen that external services triggering savepoints can not
> persist the savepoint location from the savepoint handler, because the
> operation cache has a hardcoded value of 5 minutes, until entries (which have
> been accessed at least once) are evicted.
> To avoid scenarios where the savepoint location has been accessed, but the
> external system failed to persist the location, I propose to make this
> eviction timeout configurable (so that I as a user can configure a value of
> 24 hours for the cache eviction).
