-----------------------------------------
Summary: Support distinct aggregates in window functions
Key: CALCITE-476
URL: https://issues.apache.org/jira/browse/CALCITE-476
Project: Calcite
Issue Type: Bug
Affects Versions: 1.0.0-incubating
Reporter: Vladimir Sitnikov
Assignee: Julian Hyde
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?
