------------------------------------
Summary: Limit followed by TopNKey improvement
Key: HIVE-23957
URL: https://issues.apache.org/jira/browse/HIVE-23957
Project: Hive
Issue Type: Improvement
Reporter: Attila Magyar
Assignee: Attila Magyar
The Limit + topnkey pushdown might result a limit operator followed by a TNK in
the physical plan. This likely makes the TNK unnecessary in cases like this.
Need to investigate if/when we can remove the TNK.
