             Summary: 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.
