Review comment:
Thanks, @jorisvandenbossche . Yes, I agree with you that we need to
optimize it in both `ORCFile` API and this one together for that case.

Thanks, @jorisvandenbossche . Yes, I agree with you that we need to
optimize it in both `ORCFile` API and this one together for that case in a
separate JIRA.
