    Description

      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.
