Subject Re: [jira] [Created] (DRILL-3619) Add support for NTILE window function
Date Mon, 10 Aug 2015 19:17:37 GMT
I got a "basic" implementation running, but it's still in testing.
It's seems to be giving correct results, but it's tied to Drill's Window
operator because it still need to compute all window functions if necessary.

All suggestions are welcome, it's always interesting to learn about
alternative ways to implement the same feature.

Thanks
