> This is a follow-up task of ORC-1012. Currently we have options for the tools to work on specified top-level column fields. However, ACID ORC files usually have nested structure. We need the type ids to specify nested columns. As an extension, adding support for column names will also be helpful. So we don't need to manually convert column names to type ids.
