[jira] [Commented] (DRILL-315) Reading only select columns from a parquet file

    [ https://issues.apache.org/jira/browse/DRILL-315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13835963#comment-13835963 ] 

Timothy Chen commented on DRILL-315:
------------------------------------

Definitely shouldn't do a per object filter, but using metadata such as statistics/indexes when they are available in Parquet.
Perhaps remove the stuff that isn't related to the patch? I see a byte[200] read that isn't related to anything as well.
