Nishant Bangarwa commented on HIVE-15641:
-----------------------------------------
checked with the latest calcite MASTER, looks like it is still an issue after a
CAST also.
Will look into this further.
> Hive/Druid integration: filter on timestamp not pushed to DruidQuery
> --------------------------------------------------------------------
>
> Key: HIVE-15641
> URL: https://issues.apache.org/jira/browse/HIVE-15641
> Project: Hive
> Issue Type: Improvement
> Components: Druid integration
> Affects Versions: 2.2.0
> Reporter: Jesus Camacho Rodriguez
> Assignee: Jesus Camacho Rodriguez
>
> 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.
