Programming a database is fascinating work. I’ve been deeply involved with developing open source databases for the past two years and programming a database is possibly the most instructive project one can ever complete as a software developer.
What’s really striking however, is how much my attitude towards databases has changed over the past 6 years. From a state of disinterest, I’ve come to think of these systems as a pinnacle of software engineering.

rqlite is a replicated SQLite database, with distributed consensus provided by the Raft consensus protocol. Written in Go v2.0 is now out. This release is a significant upgrade relative to v1.0.

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 go-raft is no longer maintained, and I’ve good experience with the Hashicorp code, due to my work with InfluxDB and hraftd.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.
I recently presented at the InfluxDB San Francisco Meetup, on InfluxDB and the Raft consensus protocol. My talk was about the fundamental problems of distributed systems, and how InfluxDB uses Raft to solve these issues.

When you’d like to contribute to an open-source project it can be difficult to know where to start. Check out my latest post for the InfluxDB blog, explaining how we on the Core team have curated a set of issues, hopefully making it easy for potential contributors to start.
Another post for the InfluxDB blog — on testing the storage engines within InfluxDB.

I always use the names of economists for my machines’ hostnames. keynes, friedman, marx, fisher, ricardo.
So every so often the strange economics of open-source software hits me.

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.
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.
