> Cleanup timers lead to unbounded state accumulation in global window
> --------------------------------------------------------------------
>
> Key: BEAM-10760
> URL: https://issues.apache.org/jira/browse/BEAM-10760
> Project: Beam
> Issue Type: Bug
> Components: runner-core, runner-flink
> Affects Versions: 2.21.0
> Reporter: Thomas Weise
> Assignee: Thomas Weise
> Priority: P2
> Time Spent: 5h 20m
> Remaining Estimate: 0h
>
> For each key, the runner sets a cleanup timer that is designed to garbage
> collect state at the end of a window. For a global window, these timers will
> stay around until the pipeline terminates. Depending on the key cardinality,
> this can lead to unbounded state growth, which in the case of the Flink
> runner is observable in the growth of checkpoint size.
