Description
Similar to HIVE-15636, but for GroupBy queries. Limit is applied per granularity unit, not globally for the query.
SELECT i_brand_id, floor_day(`__time`), max(ss_quantity), sum(ss_wholesale_cost) as s FROM store_sales_sold_time_subset GROUP BY i_brand_id, floor_day(`__time`) ORDER BY s LIMIT 10; OK Plan optimized by CBO.
