[jira] [Created] (FLINK-11188) Bounded over should not enable state retention time

Hequn Cheng created FLINK-11188:
-----------------------------------

             Summary: Bounded over should not enable state retention time 
                 Key: FLINK-11188
                 URL: https://issues.apache.org/jira/browse/FLINK-11188
             Project: Flink
          Issue Type: Bug
          Components: Table API &amp; SQL
            Reporter: Hequn Cheng
            Assignee: Hequn Cheng


As discussed in FLINK-11172, time-based operations (GROUP BY windows, OVER windows, time-windowed join, etc.) are inherently bound by time and automatically clean up their state. We should not add state cleanup or TTL for these operators.

If I understand correctly, we should not add the retention logic for rows-bounded operations either. I think we should disable state retention logic for:
 - ProcTimeBoundedRangeOver
 - ProcTimeBoundedRowsOver
 - RowTimeBoundedRangeOver
 - RowTimeBoundedRowsOver

Any suggestions are appreciated!
