A Go library implementing the core Raft consensus algorithm for maintaining a replicated state machine across a cluster of nodes. It deliberately excludes networking and storage, leaving transport and persistence layers to the user for maximum flexibility and determinism.

Use cases

• build a replicated state machine with raft consensus
• implement leader election and log replication in a distributed system
• add consensus to a distributed database or key-value store
• implement linearizable read-only queries in a cluster
• learn how the raft consensus algorithm works in production code

When to choose

• you need a battle-tested, production-proven raft implementation powering etcd, Kubernetes, CockroachDB, and TiDB
• you want full control over networking and storage layers
• you need a deterministic, minimal core algorithm library
• you need advanced features like membership changes, leadership transfer, and log compaction

When to avoid

• you want an out-of-the-box distributed system with networking and storage included
• you need a monolithic raft solution with built-in transport
• your project is not written in Go
