Windowing Analytic Queries

Hi,
Does Kylin accelerate Windowing analytic queries (OVER clause)?
Any roadmap?
Thanks,
Best,

Kylin master branch now supports window function.
https://issues.apache.org/jira/browse/KYLIN-1732

Acceleration is indirect. Kylin pre-calculates the aggregations underneath,
while the window function is still runtime calculation.
