PengYang created FLINK-10250:
--------------------------------

             Summary: Flink doesn't support functions that extend RichAggregateFunction in a group window
                 Key: FLINK-10250
                 URL: https://issues.apache.org/jira/browse/FLINK-10250
             Project: Flink
          Issue Type: Improvement
          Components: DataStream API
    Affects Versions: 1.6.0, 1.5.3, 1.5.2
            Reporter: PengYang


Flink doesn't support functions that extend RichAggregateFunction in a group window,in the RichAggregateFunction via state store data and fliter out the duplicate data .The Flink will support this feature in a future release?There is another question whether flink supports global state state query in the future?If flink supports global state queries, it can replace redis these external caches In certain aspects.Maybe my thoughts are a little naive, but I hope that the function of flink is getting better and better
