[jira] [Created] (FLINK-17446) Blink supports cube and window together in group by

Liu created FLINK-17446:
---------------------------

             Summary: Blink supports cube and window together in group by
                 Key: FLINK-17446
                 URL: https://issues.apache.org/jira/browse/FLINK-17446
             Project: Flink
          Issue Type: New Feature
          Components: API / Core
            Reporter: Liu


      Blink planner supports CUBE. CUBE can be used together with a field but not window. For example, the following SQL is not supported:

 
      SELECT A, B, sum(C)
       FROM person
      GROUP BY cube(A, B), TUMBLE(curTimestamp, interval '1' minute)
 
      It is a missing feature. Maybe it should be supported. Detail is in [user mailing list|[http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Blink-window-and-cube-td34761.html#a34768]]
