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

     [ https://issues.apache.org/jira/browse/FLINK-17446?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Liu updated FLINK-17446:
------------------------
    Description: 
      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 [http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Blink-window-and-cube-td34761.html#a34768]
