sankalp kohli commented on CASSANDRA-6246:
------------------------------------------
In PreacceptCallback
boolean fpQuorum = numResponses >= participantInfo.fastQuorumSize; //will be
always false since we don't accept any requests after quorum number of requests
have got in. This will cause accept phase to run always even if there is no
contention.
Am I reading it right?

> Key: CASSANDRA-6246
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6246
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Jonathan Ellis
> Assignee: Blake Eggleston
> Priority: Minor
>
> 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:

> However, there is substantial additional complexity involved if we choose to
> implement it.
