Raft is a consensus algorithm created to be easily understandable while maintaining equivalent fault-tolerance and performance to Paxos. It breaks down the consensus problem into independent subproblems, addressing all key areas needed for practical implementations. The goal of Raft is to make consensus algorithms more accessible, enabling the development of higher-quality consensus-based systems. Consensus is critical in fault-tolerant distributed systems, where multiple servers must agree on values. A decision becomes final once reached, and consensus algorithms can progress as long
