Pengcheng Xiong commented on HIVE-15641:
----------------------------------------

Hello, I am deferring this to Hive 3.0 as we are going to cut the first RC and 
it is not marked as blocker. Please feel free to commit to the branch if this 
can be resolved before the release.

> It seems we are missing opportunity push Filter operation to DruidQuery.
> For instance, for the following query:
> {code:sql}
> EXPLAIN
> SELECT i_brand_id, floor_day(`__time`), max(ss_quantity), 
> sum(ss_wholesale_cost) as s
> FROM store_sales_sold_time_subset
> WHERE floor_day(`__time`) BETWEEN '1999-11-01 00:00:00' AND '1999-11-10 
> 00:00:00'
> GROUP BY i_brand_id, floor_day(`__time`)
> ORDER BY s
> LIMIT 10;
> OK
> Plan optimized by CBO.
