    Window operator has become increasingly complex. I already opened [DRILL-3662](https://issues.apache.org/jira/browse/DRILL-3662) to refactor the code.

> as part of the review for DRILL-3536 two main comments were left aside and will be addressed by this JIRA:
> - refactor DefaultFrameTemplate into separate templates, each one handles a different "family" of window functions (e.g. aggregate vs ranking)
> - setupEvaluatePeer() should not be called more than once per incoming batch
