## What it is
SOFAJRaft is a production-grade, high-performance Java implementation of the RAFT consensus algorithm, ported from Baidu's braft. It supports multi-raft-group deployment for high-load, low-latency scenarios and includes an embedded distributed KV storage implementation.

## Use cases
- build a replicated state machine in Java
- implement a fault-tolerant distributed key-value store
- add leader election and log replication to a distributed system
- achieve linearizable reads with ReadIndex or lease-based reads
- run multiple raft groups for high-throughput sharded storage
- verify cluster consistency under network partitions

## When to choose
- you need a battle-tested, Jepsen-verified RAFT implementation on the JVM
- you want snapshotting, log compaction, and membership changes out of the box
- you need multi-raft-group support for high-load, low-latency workloads
- you prefer a pure Java library with Maven Central availability

## When to avoid
- you need a C++ or non-JVM RAFT implementation
- you only need a simple single-node storage solution without replication
- your project requires a language other than Java or JVM compatibility

## Facets
- artifact type: library
- maturity: stable
- function: concurrency, developer-tools, sdk
- domain: microservices, databases, developer-tools
- platform: jvm, windows, cross-platform
- tags: raft, consensus, replication, multi-raft, jepsen-tested, distributed-storage, high-availability, algorithms, linux, macos
