Call me maybe: Cassandra

“Cassandra is a Dynamo system; like Riak, it divides a hash ring into a several chunks, and keeps N replicas of each chunk on different nodes. It uses tunable quorums, hinted handoff, and active anti-entropy to keep replicas up to date. Unlike the Dynamo paper and some of its peers, Cassandra eschews vector clocks in favor of a pure last-write-wins approach…”
