This project is deprecated. Please see the tidwall/raft-wal project for a more advanced raft log.

raft-buntdb

For a better and faster Raft store please see the raft-fastlog project.

This repository provides the raftbuntdb package. The package exports the BuntStore which is an implementation of both a LogStore and StableStore.

It is meant to be used as a backend for the raft package here.

This implementation uses BuntDB. BuntDB is an in-memory database that persists to disk and is written in pure Go. It includes transactions, is ACID compliant, and is very fast.
