Josh Mahonin commented on PHOENIX-3601:
---------------------------------------
Definitely an awesome improvement, although perhaps a bit embarrassing... :)
In theory, the perf. boost should be observable in MapReduce, Pig, or any other
execution engine that makes use of the PhoenixInputSplit. I think Spark's
pretty neat though, myself.
