I see. Thanks for the clarifications.

> Any time we add a byte array to a protobuf, it'll copy the byte array.
> I was playing with the client and noticed how a bunch of CPU and copying was
> being done just to copy basic arrays doing pb construction. I started to
> look at ByteString and then remembered a class Benoit sent me a while back
> that I did not understand from his new AsyncHBase. After looking in
> ByteString it made now sense. So, rather than copy byte arrays everywhere,
> do a version of a ByteString that instead wraps the array.
