Subject [jira] [Commented] (HIVE-4246) Implement predicate pushdown for ORC
Date Thu, 15 Aug 2013 19:04:57 GMT


Gunther Hagleitner commented on HIVE-4246:

The failing test is unrelated. What's worse I can reproduce it on trunk w/o any changes. I
will open jira for that.

> 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.
