Nicolas Liochon commented on HBASE-9868:
----------------------------------------
v2 takes into account the changes in HBASE-9867.
I also removed two protobuf builder object creation in a loop. We've got a
bunch of work in this area ahead of us. Likely removing the class-in-the-middle
and use differently the builder pattern is the way to go...
> Remove some array copy, especially around protobuf
