> State cleanup interferes with user timer callback
> -------------------------------------------------
>
> Key: BEAM-7112
> URL: https://issues.apache.org/jira/browse/BEAM-7112
> Project: Beam
> Issue Type: Bug
> Components: runner-flink
> Affects Versions: 2.12.0
> Reporter: Thomas Weise
> Assignee: Thomas Weise
> Priority: Major
> Labels: portability-flink
> Time Spent: 2h 40m
> Remaining Estimate: 0h
>
> Cleanup timers and user timers are fired at the watermark. Processing of
> timers in the SDK worker is asynchronous, so it is possible that the state is
> already removed when the user timer callback executes.
