Peter Bailis commented on CASSANDRA-7056:
-----------------------------------------
As I mentioned at the Next-Generation Cassandra Conference, I'm happy to get
the ball rolling on an implementation of RAMP in Cassandra.
To reiterate a few points from the NGCC, I think RAMP could provide some useful
isolation guarantees for Cassandra's Atomic Batch operations (either none of
the updates will be visible, or all are visible) as well as provide the basis
for "consistent" global secondary index updates in Cassandra-6477. I've posted
my slides from the NGCC on SpeakerDeck; the Cassandra-specific implementation
details start on transition number 287.

I have some time to hack on this and am willing to work on a patch and/or
hammer out the Cassandra-specific design with you all over JIRA or otherwise!
