Subject [jira] [Commented] (DRILL-315) Reading only select columns from a parquet file
Date Mon, 02 Dec 2013 03:08:37 GMT

    [ https://issues.apache.org/jira/browse/DRILL-315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13836195#comment-13836195

Jacques Nadeau commented on DRILL-315:

I agree, let's only include the column lists for now in this patch.  How does one just pick
all the columns?

I've built on top of your stuff to try reduce copies and improve read performance.  Take my
stuff and merge into a single patch and then let's discuss.  You can find my additions at:
