> 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.
