*rqlite* is a distributed relational database, which uses [SQLite](https://www.sqlite.org/) as its storage engine. rqlite uses [Raft](https://raft.github.io/) to achieve consensus across all the instances of the SQLite databases, ensuring 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. rqlite is available for Linux, OSX, and Microsoft Windows.
*rqlite* is a lightweight, distributed relational database, which uses [SQLite](https://www.sqlite.org/) as its storage engine. It gracefully handles leader elections, and tolerates failures of machines, including the leader. rqlite is available for Linux, OSX, and Microsoft Windows.
### 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 relational data store**. 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.
## How?
rqlite uses [Raft](https://raft.github.io/) to achieve consensus across all the instances of the SQLite databases, ensuring that every change made to the system is made to a quorum of SQLite databases, or none at all. You can learn more about the design [here](https://github.com/rqlite/rqlite/blob/master/DOC/DESIGN.md).
### Key features
- Very easy deployment, with no need to separately install SQLite.
