             Summary: Add config option to close Hash window agg since hash 
will lead to OOM
                 Key: FLINK-15732
                 URL: https://issues.apache.org/jira/browse/FLINK-15732
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Planner
            Reporter: Jingsong Lee
             Fix For: 1.11.0


Now in table blink batch mode, we choose hash window agg, but sometimes hash 
agg will lead to OOM because manage memory not enough.

We should give users ability to close hash window agg, and using sort agg will 
more stable.
