> 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.
