Date Thu, 07 Aug 2014 16:22:12 GMT

Josh Wills commented on CRUNCH-450:
-----------------------------------

Yeah, I'm a fan of this approach; the OrcFileWriter is a nice addition and is the kind of
construct we should be thinking about for all Sources and Targets. Will be cool to see how
the tuple and reflection-based Orc-impls come along!
