-----------------------------------
Summary: Excessive state updates for TtlMapState and TtlListState
Key: FLINK-30088
URL: https://issues.apache.org/jira/browse/FLINK-30088
Project: Flink
Issue Type: Bug
Reporter: Roman Boyko

After merging the FLINK-21413 every ttl check for cleanup for TtlMapState and
TtlListState (even without expired elements) leads to whole state update.
This is because:
- comparison by link inside `TtlIncrementalCleanup`:
!image-2022-11-18-20-25-14-466.png|width=450,height=288!
- and creating new map or list inside TtlMapState or TtlListState:
