> 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.
