rqlite on GitHubrqlite is an open-source distributed relational database, which uses SQLite as its storage engine. rqlite is written in Go and uses Raft to achieve consensus across a set of SQLite databases. It gracefully handles leader election, and can tolerate machine failure.

With the v3 release series, rqlite can now replicate SQLite databases on a global scale, with very little effort. Let’s see it in action using the AWS EC2 cloud.

What’s really striking however, is how much my attitude towards databases has changed over the past 6 years. From a state of disinterest, I’ve come to think of these systems as a pinnacle of software engineering.

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.
