Subject [jira] [Commented] (HIVE-4242) Predicate push down should also be provided to InputFormats
Date Mon, 19 May 2014 18:06:38 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14002081#comment-14002081

Sergey Shelukhin commented on HIVE-4242:
----------------------------------------

The patch sets the filter unconditionally. Should it rather change the config setting or add
a new one?

> Currently, the push down predicate is only provided to native tables if the hive.optimize.index.filter
configuration variable is set. There is no reason to prevent InputFormats from getting the
required information to do predicate push down.
> Obviously, this will be very useful for ORC.
