------------------------------------------------

I think if we are going to avoid the copy for non-java clients also - then should we also handle the CallBack in RPC response that we do now for the CellScanner case? I think yes? May be missing something? [~anoopsamjohn].

> Since we now have support for BBs in UnsafeByteOperations#unsafeWrap(ByteBuffer) . So for the non - java clients while creating the PB result we could avoid the copy to an temp array. 
> Since we have a support to write to BB in ByteOutput having a result backed by Bytebuffer should be fine.
