> I've done some working testing various ways to refactor and optimize Scans in HBase,
and have found that performance can be dramatically increased by the addition of a streaming
scan API.  The attached code constitutes a proof of concept that shows performance increases
of almost 4x in some workloads.
> I'd appreciate testing, replication, and comments.  If the approach seems viable, I think
such an API should be built into some future version of HBase.
