sankalp kohli commented on CASSANDRA-6246:
------------------------------------------

I am a little confused as in how you will use epoch to make sure instances are executed on
all replicas when incrementing?

> One reason we haven't optimized our Paxos implementation with Multi-paxos is that Multi-paxos
requires leader election and hence, a period of unavailability when the leader dies.
> EPaxos is a Paxos variant that requires (1) less messages than multi-paxos, (2) is particularly
useful across multiple datacenters, and (3) allows any node to act as coordinator: http://sigops.org/sosp/sosp13/papers/p358-moraru.pdf
> However, there is substantial additional complexity involved if we choose to implement
it.
