Importance of calling mapState.clear() when no entries in mapState

[idkfaon]

Hi,

given:
- flink 1.6.1
- stateful function with MapState<K, V> mapState = //init logic;

Is there any reason I should call mapState.clear() if I know beforehand that there are no entries in mapState (e.g. mapState.iterator().hasNext() returns false)?

Thanks in advance!

I think there should be no reason to do that.

Best,

Dawid
