Jacques Nadeau commented on DRILL-3987:
---------------------------------------
One of the things I'm looking at here what is the right separation between
describing schema and Drill's concept of materialized field and schemapath. It
seems like we need a simplified MaterializedField in the vector classes and
then a specialization that supports things like Drill's logical expressions in
the Drill codebase. What do you think [~hgunes]?

> I'd like to start by looking at an extraction that pulls out the base
> concepts of:
> buffer allocation, value vectors and complexwriter/fieldreader.
> I need to figure out how to resolve some of the cross-dependency issues (such
> as the jdbc accessor connections).
