> ORC data doesn't have to go directly into an HDFS stream via buffers, it can
> go somewhere else (e.g. a write-thru cache, or an addressable system that
> doesn't require the stream blocks to be held in memory before writing them
> all together).
> To that effect, it would be nice to abstract the data block/metadata
> structure creating from the physical file concerns.
