Harish Butani created HIVE-7063: ----------------------------------- Summary: Optimize for the Top N within a Group use case Key: HIVE-7063 URL: https://issues.apache.org/jira/browse/HIVE-7063 Project: Hive Issue Type: Bug Reporter: Harish Butani Assignee: Harish Butani
It is common to rank within a Group/Partition and then only return the Top N entries within each Group. With Streaming mode for Windowing, we should push the post filter on the rank into the Windowing processing as a Limit expression. -- This message was sent by Atlassian JIRA (v6.2#6252)
