Jean-Marc Spaggiari commented on HBASE-15820:
---------------------------------------------
Yeah, I checked for the references. Arrays are copied in the methods that are
called. So it's fine. And it's all small arrays here, so it should be fine.
Just sad that it's not used that much. There is also optimization on filters,
etc. But again, small usage.
> Re-using byte[] from Bytes can save some objects creations
