   @wuchong  hello jark, I get a expception by below SQL, and find out : the local and global window aggregate operator support insert-only in input right now. Why ? There is any limition in this case?
   
   `SELECT count(0), sum(score),window_start,window_end, window_time FROM TABLE(
       CUMULATE(TABLE UserScores_event, DESCRIPTOR(tt), INTERVAL '10' SECONDS, INTERVAL '60' SECONDS))
    group by window_start,window_end, window_time`
