Sylvain Lebresne updated CASSANDRA-6246: ---------------------------------------- Reviewer: (was: Sylvain Lebresne) > EPaxos > ------ > > Key: CASSANDRA-6246 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6246 > Project: Cassandra > Issue Type: Improvement > Reporter: Jonathan Ellis > Assignee: Blake Eggleston > Labels: messaging-service-bump-required > Fix For: 4.x > > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
