Raft Consensus Algorithm Mastering Distributed Systems In this cockroach university lesson titled “the raft protocol explained via sql database", you will learn about the raft protocol (the consensus algorithm) and how it’s used. Learn more about our privacy practices here.
You Must Build A Raft Consul S Consensus Protocol Explained Each and every range in cockroachdb is fundamentally a raft group (with a lot of garnish around it). raft is a consensus protocol that provides a distributed state machine being fed an ordered log of commands, the raft log. Cockroachdb is a distributed sql database designed to be highly available, scalable, and resilient to failures — much like the insect it's named after. it’s postgresql compatible and aims to offer the scalability of nosql with the consistency and familiarity of sql. The database uses raft to operate seamlessly for short term failures as long as most replicas remain available. for longer term failures, the database automatically creates new replicas of under replicated ranges. In this second part, we’ll uncover how cockroachdb uses the raft consensus algorithm, multi version concurrency control (mvcc), and its pebble storage engine to achieve the resilience.

Most engineers learn raft through the classic “3 node cluster” examples — one leader, two followers, a few log entries, and some heartbeats flying around. but what happens when you run hundreds. It provides a postgresql compatible sql interface built on top of a transactional, strongly consistent key value store. the system achieves horizontal scalability through range based data partitioning and raft consensus for replication. Raft is used in etcd (kubernetes' backing store), cockroachdb, tikv, consul, and hashicorp vault. these systems rely on raft to replicate state consistently across nodes and survive failures without data loss. What is raft? raft is a consensus algorithm that is designed to be easy to understand. it's equivalent to paxos in fault tolerance and performance. the difference is that it's decomposed into relatively independent subproblems, and it cleanly addresses all major pieces needed for practical systems.
