braft is an industrial-grade C++ implementation of the RAFT consensus algorithm and replicated state machine, built on top of brpc. It is designed for high-throughput, low-latency scenarios and is widely used inside Baidu to build highly-available distributed systems such as storage engines, SQL clusters, and metadata services.

Use cases

• build a highly-available distributed key-value store
• implement leader election and log replication for a distributed system
• replicate state across nodes for fault tolerance
• build a metadata or lock service with strong consistency
• add consensus to a NewSQL or distributed transaction system

When to choose

• you need production-proven RAFT consensus in C++ with high performance
• your stack already uses brpc or Baidu infrastructure
• you are building distributed storage, SQL, or meta services requiring strong consistency

When to avoid

• you need a consensus library in another language like Go, Java, or Rust
• you want a batteries-included distributed database rather than a consensus library
• your project cannot take a brpc dependency
