> Using st(reaming)ORC 
> (hive.exec.orc.delta.streaming.optimizations.enabled=true) format has massive 
> performance advantages when creating data-sets which will not be stored for 
> long-term.
> The format is compatible with ORC for vectorization and other features, while 
> being cheaper to write out to filesystem.
