[jira] [Created] (CALCITE-1345) Streaming GROUP BY

Julian Hyde created CALCITE-1345:
------------------------------------

             Summary: Streaming GROUP BY
                 Key: CALCITE-1345
                 URL: https://issues.apache.org/jira/browse/CALCITE-1345
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Atri Sharma


Implement streaming {{GROUP BY}}, including parsing, validation, and execution using the Interpreter (probably a variation of AggregateNode), intermittently returning results when a monotonic column indicates that the next set of results are ready. Add test(s) to StreamingTest. Example query should include {{FLOOR(rowtime TO HOUR)}}; the {{TUMBLE}}, {{HOP}} and {{SESSION}} functions are out of scope of this JIRA case.
