rqlite is a lightweight, distributed relational database, which uses SQLite as its storage engine. rqlite provides an easy-to-use, fault-tolerant store for critical relational data.
Release 5.1.0 adds support for new read-only nodes. This allows you to add nodes to the cluster that act purely as read-replicas, and do not participate in Raft consensus. Before this change all nodes participated in consensus, which meant adding nodes could affect write throughput, but with this new node type this is no longer the case.
See the CHANGELOG for full details on this release.

Getting started
To download and run a single rqlite node, which automatically becomes leader, follow the directions below. It's also very easy to run a rqlite cluster -- you can learn more by checking out the documentation.
Linux
To download and start rqlite on Linux, execute the following in a shell.
curl -L https://github.com/rqlite/rqlite/releases/download/v5.1.0/rqlite-v5.1.0-linux-amd64.tar.gz -o rqlite-v5.1.0-linux-amd64.tar.gz
tar xvfz rqlite-v5.1.0-linux-amd64.tar.gz
cd rqlite-v5.1.0-linux-amd64
./rqlited ~/node.1
OSX
To download and start rqlite on OSX, execute the following in a shell.
curl -L https://github.com/rqlite/rqlite/releases/download/v5.1.0/rqlite-v5.1.0-darwin-amd64.tar.gz -o rqlite-v5.1.0-darwin-amd64.tar.gz
tar xvfz rqlite-v5.1.0-darwin-amd64.tar.gz
cd rqlite-v5.1.0-darwin-amd64
./rqlited ~/node.1
Windows
rqlite can be built for Windows, and compatibility is ensured at all times via AppVeyor. However you may need to build a specific release yourself, though the top-of-tree build is available for download from AppVeyor. Check out the CI build for Windows for more details.
