             Summary: Make CompletedOperationCache.COMPLETED_OPERATION_RESULT_CACHE_DURATION_SECONDS configurable (at least for savepoint trigger operations)
                 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


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).
