Piotr Nowojski commented on FLINK-24182: ---------------------------------------- I would also link this issue with FLINK-24184 and fix both of them at the same time. > Tasks canceler should not immediately interrupt > ----------------------------------------------- > > Key: FLINK-24182 > URL: https://issues.apache.org/jira/browse/FLINK-24182 > Project: Flink > Issue Type: Improvement > Components: Runtime / Task > Reporter: Arvid Heise > Priority: Major > > While debugging resource leaks (FLINK-24131), I found that any connector is > immediately interrupted on cancel. Hence, any attempts of using blocking > calls in {{close}} to cleanup resources are immediately unreliable (e.g. > aborting transactions). > It would be nice if tasks get a grace period (e.g. > task.cancellation.interval) where they can try to free resources in a proper, > potentially blocking fashion before being interrupted. > Nevertheless, connectors should always expect interruptions during shutdown, > in particular when the user-configurable grace period is depleted. I'd add > that to the connector documentation in a separate effort. -- This message was sent by Atlassian Jira (v8.3.4#803005)
