Lyn Zhang updated FLINK-25695:
------------------------------
Description:
Last year, I reported the similar bug of TemporalJoin cause state leak.
Detail: [https://github.com/apache/flink/pull/14916]
Recently, I found the fix code can reduce the the leak size but can not resolve
it completely.
The code of line 213 cause that and The right fix is to invoke cleanUp() method.
The [https://github.com/apache/flink/pull/14916] We discussed that if the code
is running on line 213, That meaning 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.
