Cassandra + RAMP transactions
Hi,
Please forgive me if this is not the right forum for this query.
I recently read an article where Jonathan Ellis mentioned that ePaxos and
RAMP transactions should be soon added to Cassandra.
Is there any work going on in this direction?
Thanks

I've been working on the epaxos implementation. You can take a look at the
ticket here: https://issues.apache.org/jira/browse/CASSANDRA-6246

That would be great! By all means, it's open to work on. Please
comment on the ticket if you get stuck, have questions etc.

Hi,
We are a team of 3 graduate students in Computer Science at University of
Illinois at Urbana Champaign.
We were thinking of adding support for RAMP transactions to Cassandra, as
part of our Advanced Distributed Systems project work.
I have looked at the associated ticket that Tupspin mentioned in the
previous email, and it appears that there is a blocking issue mentioned in
the discussion.
To be clear, using non-unique ts as RAMP id is broken, but I agree that we
should proceed here with the assumption that we'll solve the unique ts
problem; if that doesn't work out we can figure out a plan B.
I'd like to get a green-signal from the developer community. Also, any
information that would help us such as internal class hierarchy, other
implementation design details of Cassandra and your feedback on the
blocking issue that I mentioned.
Thanks

Hi Jatin,
I believe there is a lot of interest in developing RAMP transactions for
Cassandra, but no concrete activity yet.
