----------------------------------
Summary: Remove predicate on partition columns from Table Scan
operator
Key: HIVE-21599
URL: https://issues.apache.org/jira/browse/HIVE-21599
Project: Hive
Issue Type: Improvement
Components: Query Planning
Reporter: Vineet Garg
Assignee: Vineet Garg
Filter predicates are pushed to Table Scan (to be pushed to and used by storage
handler/input format). Such predicates could consist of partition columns which
are of no use to storage handler or input formats. Therefore it should be
removed from TS filter expression.
