[jira] [Created] (BEAM-2006) window support

Xu Mingmin created BEAM-2006:
--------------------------------

             Summary: window support 
                 Key: BEAM-2006
                 URL: https://issues.apache.org/jira/browse/BEAM-2006
             Project: Beam
          Issue Type: New Feature
          Components: dsl-sql
            Reporter: Xu Mingmin
            Assignee: Xu Mingmin


There're several methods, TUMBLE/HOP/SESSION, introduced in Calcite 1.12, which represent a window-aggregation operation. 

In BeamSQL, it's expected to leverage these methods to determine window function, set trigger strategy, also handle event_time/watermark properly.
