Benedict commented on CASSANDRA-6689:
-------------------------------------
Can everyone please settle on what functionality is desired for this
ticket/release, so I do not need to keep reorganising it. I am in the middle of
rebasing and reorganising it again, but I will wait until some consensus is
reached. If we only want #2 (#1 is useless on its own), the patch set will be
quite different; I will drop all of the refactoring. If we plan to include #3
(note that this quite provably reduces fixed on-heap overhead by a minimum of
75%, and easily > 90% for clustering columns), I will retain #1 with some minor
tweaks, and do my best to further make the commits incremental, but I am not
going to completely reorder everything for no good reason.
