LogCabin Project


LogCabin is a distributed system that provides a small amount of highly replicated, consistent storage. It is a reliable place for other distributed systems to store their core metadata and is helpful in solving cluster management issues.

We've written a paper about the Raft consensus algorithm which LogCabin uses internally: read it here (PDF).
