rqlite v3.0.1 released with leader redirection

rqliterqlite is an open-source distributed relational database, with SQLite as its storage engine. v3.0.1 has been released and it is a significant upgrade relative to the 2.0 series. The 3.0 series allows more sophisticated clusters to be built and simplifies rqlite client coding requirements.

rqlite – replicated SQLite with new Raft consensus and API

Raft consensus protocolrqlite provides robust replication for SQLite databases using the Raft consensus protocol. Coded in Go it ensures that all changes made to the leader SQLite database are replicated to all other nodes in the cluster, providing fault-tolerance and reliability.

It’s been 18 months since development of rqlite first started and it’s time for version 2.

rqlite and Hashicorp Raft Consensus

Hashicorp RaftI’ve started replacing go-raft within rqlite with the implementation from Hashicorp. go-raft is no longer maintained, and I’ve good experience with the Hashicorp code, due to my work with InfluxDB and hraftd. I’m also going to change the API, so it’s more useful. The existing implementation and API has been tagged as v1.0, so it’s still available.

You can follow the work on this branch, and I hope to merge it to master in the near future.

Replicating SQLite using Raft Consensus

raft-logoSQLite is a “self-contained, serverless, zero-configuration, transactional SQL database engine”.  However, it doesn’t come with replication built in, so if you want to store mission-critical data in it, you better back it up. The usual approach is to continually copy the SQLite file on every change.

I wanted SQLite, I wanted it distributed, and I really wanted a more elegant solution for replication. So rqlite was born.
