Raft consistency
WebRaft is a consensus algorithm designed as an alternative to the Paxos family of algorithms. It was meant to be more understandable than Paxos by means of separation of logic, but it is also formally proven safe and offers some additional features. Raft offers a generic way to distribute a state machine across a cluster of computing systems, ensuring that each … WebMay 14, 2024 · Consensus is one of the most important challenges in designing and building distributed systems–how to make sure multiple nodes (or agents, processes, threads, tasks, participants, etc.) in a group agree on a specific value proposed by at least one of the nodes. As an open-source distributed transactional key-value database, TiKV uses the Raft …
