Owen O'Malley created HIVE-4246: ----------------------------------- Summary: Implement predicate pushdown for ORC Key: HIVE-4246 URL: https://issues.apache.org/jira/browse/HIVE-4246 Project: Hive Issue Type: New Feature Reporter: Owen O'Malley Assignee: Owen O'Malley
By using the push down predicates from the table scan operator, ORC can skip over 10,000 rows at a time that won't satisfy the predicate. This will help a lot, especially if the file is sorted by the column that is used in the predicate. -- This message is automatically generated by JIRA.
