RAFT CONSENSUS IN 2,000 WORDS

Summary from the TLDR Dev newsletter

The Raft consensus algorithm allows multiple servers to act as a single reliable system, even with failures. Raft elects a leader to manage log replication to followers, making sure of data consistency using AppendEntries messages and an induction process. Leader election is based on up-to-date logs and majority votes, guaranteeing leader completeness and state machine safety.
