fix will be included in TokuMX.0. Conceptually, two-phase commit is is kirkland toilet paper safe for rv straightforward; the commit-request phase (or call it the voting phase and the commit phase, where the coordinator decides whether to commit or not, based on the information gathered in the voting phase. Uses of Paxos, google: the, chubby distributed lock service ( BigTable uses Chubby). More reading on consensus: And Papers We Love has a whole section on distributed systems 2PC - two-phase commit. It assumes there is storage that can be trusted at each node, that no node crashes, and that nodes can communicate with each other. By, roberto Zicari, september 23, 2014, a New Consensus Algorithm for TokuMX and MongoDB. A Technology White, Tokutek, Paper Fall 2014, copyright 2014 Tokutek, Inc. This seems a little draconian or elitist. But, at some point, it will contain original bits, and then all of this will turn into a bibliography. 2013 - pair of articles on Paxos. 2014 - Javascript implementation from Harry Brundage. I dont want to regurgitate what others have written, so at first this is going to be a reading list. That is, in the face of network partitions, TokuMX will maintain consistency. Ark was designed from first principles, improving on the election algorithm used by TokuMX, to fix deficiencies in MongoDBs consensus algorithms that can cause data loss. Today, the existing protocol is neither AP nor CP, when considered in the context of the CAP theorem. 2009 - A fairly clear article from the Paper Trail blog on Paxos. Other than that, its great 3PC - three-phase commit, fixes much of fragility of 2PC, although its still vulnerable to partitions. CoreOS is using Raft in etcd.
