> -------------------------------------------
>
> Key: FLINK-25695
> URL: https://issues.apache.org/jira/browse/FLINK-25695
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Runtime
> Affects Versions: 1.14.3
> Reporter: Lyn Zhang
> Priority: Critical
> Labels: pull-request-available
>
> Last year, I reported the similar bug of TemporalJoin cause state leak.
> Detail: FLINK-21833
> Recently, I found the fix code can reduce the the leak size but can not
> resolve it completely.
> The code of line 213 cause it and the right fix is to invoke cleanUp() method.
> In FLINK-21833, we discussed when the code is running on line 213, that means
> Left State, Right State, registeredTimerState is empty, actually the Left
> State and Right State value(MapState) is empty but the key is still be in
> state, So invoke state.clear() is necessary.
