raft
A stable, widely-used Go library implementing the core Raft consensus algorithm for maintaining a replicated state machine.
What is raft?
etcd-io/raft is a Go implementation of the Raft consensus algorithm, which enables a cluster of nodes to maintain a replicated state machine through a replicated log. It is the most widely used Raft library in production, powering major distributed systems like etcd, Kubernetes, and CockroachDB. The library follows a minimalistic design, focusing solely on the core algorithm to provide flexibility, determinism, and high performance.
Go developers building distributed systems that require strong consistency, such as databases, key-value stores, orchestration toolkits, and blockchain networks. It is also suitable for those who need a production-proven, embeddable consensus layer.
Developers choose this library because it is the most widely used and production-tested Raft implementation, offering a minimalistic design that decouples the core algorithm from network and storage layers for maximum flexibility and deterministic testing. Its optional performance enhancements, like pipelining and batching, provide high throughput and low latency.
