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.
> Reading only select columns from a parquet file
