Marcus Eriksson commented on CASSANDRA-6689:
--------------------------------------------
Reviewing under the assumption that 1-3 will go in 2.1 and the rest into 3.0,
otherwise there is a some of stuff in #1 that should be in #3 etc, but leaving
that aside for now.
Main point when reviewing was that I found myself trying to wrap my head around
the Group concept several times, especially since it is not actually adding any
functionality at this stage (I know it will when we do GC). We should probably
remove it since it adds indirection that we don't need right now. Pushed a
branch with the DataGroup and various Group classes in o.a.c.u.memory removed
