> 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.
