Check out this cool video, showing the evolution of the source code.
I’m a conviction engineer.
To me it’s the only way to be an effective engineer, software developer, and technical leader. You’ve simply got to truly believe in the value of what you do, and you’ve got to believe in doing it the right way.
rqlite is an open-source distributed relational database, with SQLite as its storage engine. v3.2.1 has been released and includes new functionality for cluster management, along with new documentation on running clusters. v3.2.0 also includes some bug fixes.
You can download the release from GitHub.
Some fellow developers, using Go for the first time, recently asked me how to organise a Go project and for some high-level guidance on programming using the language.
I thought the most effective way to answer this question was to build a simple Go HTTP service, that provides a key-value store. It also includes a README, outlining my most important guidelines for Go programming. You can check it out here.
rqlite is an open-source distributed relational database, which uses SQLite as its storage engine. rqlite is written in Go and uses Raft to achieve consensus across a set of SQLite databases. It gracefully handles leader election, and can tolerate machine failure.
rqlite is an open-source distributed relational database, with SQLite as its storage engine. v3.0.1 has been released and it is a significant upgrade relative to the 2.0 series. The 3.0 series allows more sophisticated clusters to be built and simplifies rqlite client coding requirements.
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.
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.
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 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.

When is the last time you spoke with your fellow developer? I mean actually spoke? Or was it just over Slack?
It’s been 18 months since the first commit to my first significant Go project — syslog-gollector. After an initial burst of activity to create a functional Syslog Collector that streamed to Apache Kafka, the source code hadn’t been updated much since. But today I received a report that it no longer built, so I spent some time porting the code to the latest Shopify Sarama framework.
It was amusing to see how naive much of my early Go code was.
