## What it is
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

## Facets
- artifact type: library
- maturity: stable
- function: concurrency, networking, rpc, developer-tools
- domain: microservices, databases, infrastructure-as-code, backend
- platform: cpp
- tags: raft-consensus, replicated-state-machine, brpc, high-availability, distributed-storage, linux, macos
