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.

I made a presentation on rqlite tonight at the San Francisco Go Meetup. It was an enjoyable evening, and I had a chance to discuss why I built rqlite, how it works, and where it might go in the future.
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.

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 go-raft is no longer maintained, and I’ve good experience with the Hashicorp code, due to my work with InfluxDB and hraftd.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.
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.

The first version of the 0.9.0 series of InfluxDB has been released. It’s alpha-quality software but all of us on the InfluxDB team are very excited to see the software reach this stage.
You can read more about the release on this blog post.
I recently acted as one of the official technical reviewers for ElasticSearch Cookbook – Second Edition by Alberto Paro. Published by Packt Publishing, the book contains a large number of “recipes” for elasticsearch.
Packt recently asked me to review their new publication Cassandra High Availability, written by Robbie Strickland.
I’ve worked with Cassandra in the past — early designs of Loggly‘s 2nd generation Log analytics platform used Cassandra as its authoritative store for log data, but we ended up pulling it and using elasticsearch as both the store and search engine.
