Migrated from https://groups.google.com/forum/#!topic/optiq-dev/8xE3PriKXmI

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?
