*rqlite* is a distributed relational database, which uses [SQLite](https://www.sqlite.org/) as its storage engine. rqlite is written in [Go](http://golang.org/) and uses [Raft](http://raftconsensus.github.io/) to achieve consensus across all the instances of the SQLite databases. rqlite ensures that every change made to the system is made to a quorum of SQLite databases, or none at all. It also gracefully handles leader elections, and tolerates failures of machines, including the leader.
### Why?
rqlite gives you the functionality of a [rock solid](http://www.sqlite.org/testing.html), fault-tolerant, replicated relational database, but with very easy installation, deployment, and operation. With it you've got a lightweight and reliable distributed store for relational data. Think [etcd](https://github.com/coreos/etcd/) or [Consul](https://github.com/hashicorp/consul), but with relational data modelling also available.

You could use rqlite as part of a larger system, as a central store for some critical relational data, without having to run a heavier solution like MySQL.
