Subject [jira] [Commented] (CRUNCH-299) Support predicate pushdown for Parquet sources
Date Fri, 22 Nov 2013 16:22:35 GMT

    [ https://issues.apache.org/jira/browse/CRUNCH-299?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13830085#comment-13830085

Tom White commented on CRUNCH-299:
----------------------------------

I'm not wild about implementing either of these since they both break encapsulation, forcing
the user to be aware of ColumnRecordFilter and write a special filter for the case of Parquet.
I don't see any better ways at the moment though.
