# logcabin/logcabin

LogCabin is a distributed storage system built on Raft that provides a small amount of highly replicated, consistent storage. It is a reliable place for other distributed systems to store their core metadata and is helpful in solving cluster management issues.

## What it is
LogCabin is a distributed storage system built on the Raft consensus algorithm that provides a small amount of highly replicated, consistent storage. It serves as a reliable metadata store for other distributed systems and helps solve cluster management issues.

## Use cases
- store core metadata for a distributed system with strong consistency
- implement cluster membership and configuration management
- learn how the Raft consensus algorithm works in a real implementation
- run a highly available replicated key-value store
- coordinate leader election and state machine replication across a cluster

## When to choose
- you need a small, strongly consistent, replicated metadata store for distributed systems coordination
- you want a reference implementation of Raft in C++
- you need reliable cluster management primitives like leader election

## When to avoid
- you need large-scale or high-throughput data storage rather than small metadata
- you want a turnkey service with rich querying or secondary indexes
- you need Windows or macOS support, since it targets Linux x86-64
