Subject [jira] [Commented] (HIVE-5391) make ORC predicate pushdown work with vectorization
Date Tue, 01 Oct 2013 22:28:25 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5391?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13783422#comment-13783422
] 

Sergey Shelukhin commented on HIVE-5391:
----------------------------------------

Discussed out of bounds... summary: the same predicates as for normal reading; ORC currently
only uses predicates during row-group loading, so no vectorization specific code should be
necessary during row processing.
