> 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.
