Robert Metzger created FLINK-24114:
--------------------------------------
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).
