Igor Zubchenok commented on CASSANDRA-6246:
-------------------------------------------
It is a pity that these lightweight transactions can not be used at full
strength due to the delay in merging this improvement. I refer to
CASSANDRA-9328. I would set the highest priority for the merging.

> 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:

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