Nick Dimiduk commented on HBASE-9834:
-------------------------------------

What's the thinking behind using ImmutableBytesWritable instead of ByteBuffer 
or ByteRange?

> Minimize byte[] copies for 'smart' clients

> 'Smart' clients (e.g. phoenix) that have in-depth knowledge of HBase often 
> bemoan the extra byte[] copies that must be done when building multiple 
> puts/deletes. We should provide a mechanism by which they can minimize these 
> copies, but still remain wire compatible.
