## What it is
Dragonboat is a feature-complete, high-performance multi-group Raft consensus library written in pure Go. It lets developers build strongly consistent, fault-tolerant distributed applications by handling leader election, log replication, snapshotting, and membership changes.

## Use cases
- build a replicated state machine in Go
- implement fault-tolerant distributed storage
- add strong consistency to a distributed system
- run multiple Raft groups for sharded consensus
- build a highly available key-value store
- replicate application state across servers

## When to choose
- you need a production-grade Raft implementation in Go
- you need to run many Raft groups at scale
- you want disk-based or memory-based state machine support
- you need TLS mutual authentication and pipelining for high-latency networks

## When to avoid
- you need a ready-made distributed database rather than a library
- your project is not in Go
- you only need single-node persistence without consensus
- you prefer an off-the-shelf etcd-style service over embedding a library

## Facets
- artifact type: library
- maturity: stable
- function: concurrency, database, middleware
- domain: microservices, databases, developer-tools
- platform: go, windows, cross-platform
- tags: raft, consensus, replicated-state-machine, fault-tolerance, multi-group, linux, macos
