Raft is a consensus algorithm designed to manage a replicated log across a distributed system. It was introduced in a paper by Diego Ongaro and John Ousterhout in 2014 as a more understandable alternative to Paxos, another well-known consensus algorithm. Raft is primarily used in distributed systems to ensure that multiple nodes (servers) can agree on the same sequence of operations, which is essential for maintaining data consistency.
