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.
