Hashicorp recently released version 1.0 of their Raft consensus package. The Hashicorp implementation, along with SQLite, forms the core of rqlite. rqlite has now been ported to release 1.0 and will be a key change in the upcoming release of rqlite 5.0.

rqlite v2.2.1 released with HTTPS, Basic Auth, and user permissions
rqlite is a replicated relational database built on SQLite, with distributed consensus provided by the Raft consensus protocol. It gracefully handles leader election, and can tolerate machine failure.
Written in Go, v2.2.1 is out now.

rqlite – replicated SQLite with new Raft consensus and API
rqlite 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
I’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 go-raft is no longer maintained, and I’ve good experience with the Hashicorp code, due to my work with InfluxDB and hraftd.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.
Building a distributed key-value store using Raft
Hashicorp provide a nice implementation of the Raft consensus protocol, and it’s at the heart of InfluxDB (amongst other systems). I wanted to experiment with a simple system built using this particular Raft implementation, so was inspired by raftd to built hraftd.
