## What it is
NuRaft is a C++ implementation of the Raft consensus algorithm packaged as a replication library. It extends the original Raft paper with production features like pre-vote, priority-based leader election, learners, async replication, and SSL/TLS support.

## Use cases
- build a replicated state machine in C++
- add fault-tolerant consensus to a distributed key-value store
- implement leader election across a cluster
- replicate logs reliably between servers
- create a highly available configuration store

## When to choose
- you need Raft consensus embedded in a C++ application
- you want production-hardened extensions like pre-vote and priority election
- you need cross-platform support including Windows
- you want a permissive Apache-2.0 licensed consensus library

## When to avoid
- you need a full turnkey distributed database rather than a library
- your stack is not C++
- you need a consensus protocol other than Raft
- you require Windows SSL support, which is not available

## Facets
- artifact type: library
- maturity: active
- function: rpc, concurrency, networking, database
- domain: microservices, databases, developer-tools
- platform: windows, cpp
- tags: raft, consensus, replication, distributed-consensus, state-machine-replication, high-availability, linux, macos
