Notes taken from the Raft paper
Replicated And Fault Tolerant Raft is a consensus algorithm for managing a replicated log. The authors claim Raft to be more understandable than Paxos because Raft separates the key elements of consensus Leader election Log replication Safety and enforces a stronger degree of coherency to reduce the number of states that must be considered. Raft also includes a new mechanism for changing cluster membership. What is a consensus algorithm Consensus algorithms allow a collection of machines to work as a coherent group that can survive the failures of some of its members....
