> Does Optiq support Windowing func with Distinct?
> Ex: select avg(distinct c_int) over(PARTITION BY key ORDER BY value ROWS
> BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) as p from t1;
> Hive support Windowing functions with "Distinct" (UDAF with Distinct).
> I am using "m_cluster.getRexBuilder().makeOver" to build window.
> Optiq doesn't seems to support distinct on Windowing Functions.
> Am i missing something?
