Benedict commented on CASSANDRA-6689:
-------------------------------------
I think my suggested split meets your requirement, but I'm not absolutely sure.
My 1-2 are refactors to bring abstractions closer; 3 is your step 1.b; 4+5 is
your step 2.
The only difference is I assume we want our own allocator, since we won't be
able to use Netty's for steps 4+5, and that we allocate Native* within the
memtable to save substantially more space than allocating ByteBuffer would.
