rqlite is a lightweight, open-source, distributed relational database written in Go, which uses SQLite as its storage engine.
7.14.2 adds various bug fixes and improvements. Most of the rqlite source code was also run through GPT-4, and many of its suggested improvements were incorporated into this release.
You can download the release from GitHub.
rqlite is a lightweight, open-source, distributed relational database written in Go, which uses SQLite as its storage engine.
I’ve been developing rqlite since 2014 and its design and implementation has evolved substantially during that time — and the design docs tell the story of what worked, and what didn’t. So what can we learn about distributed database design, from watching rqlite change over the years?

rqlite is a lightweight, open-source, distributed relational database written in Go, which uses SQLite as its storage engine. 7.14.0 has been released and adds comprehensive support for Mutual TLS.
What makes this release of rqlite different is that much of the TLS support was written using GitHub Copilot.

Stephen Wolfram
has published an eminently readable description of what ChatGPT does, how it’s designed, and offer some insights into why it appears to work so well.

is a lightweight, open-source, distributed relational database written in Go, which uses SQLite as its storage engine. Recently I introduced a high-performance write-path into rqlite and, to my great surprise, it exposed a bug in SQLite.

Recently I helped Replicated replace their use of PostgreSQL with rqlite. This brought much easier operation and high-availability to their Application Manager.

Replicated, a company which helps software vendors ship software to end users, recently migrated from PostgreSQL to rqlite. Along the way their input substantially helped improve how rqlite runs on Kubernetes — and as a result rqlite 7.10.0 is out now. This latest release is also running an upgraded version of SQLite.

7.8.0 provides more convenient options for retrieving a backup of the underlying SQLite database. The guide for running rqlite on Kubernetes has also been improved.

7.7.0 is the first release to add support for non-deterministic functions, specifically RANDOM. It accomplishes this via statement-rewriting. Many thanks to Ben Johnson for the pure-Go SQLite parser.

Star Trek
has inspired huge numbers of people to become scientists, engineers, and programmers. I’m one of them. It often inspired me to work hard, build quality systems, and never give up when looking for the root cause of a tricky bug.

rqlite is a lightweight, open-source, distributed relational database written in Go, which uses SQLite as its storage engine. 7.6.0 improves access-control options, and also has official ARM and ARM64 builds for the first time.

I recently started reading Building Secure and Reliable Systems, which was authored by various folks at Google (some of whom I know). Since my work is at the intersection of so much of this — reliable logging systems which must also be secure, it’s an interesting read.
In my experience, the most challenging part about securing our systems are the constant trade-offs one needs to make. Since no system can be made 100% secure, knowing where the marginal risk is no longer worth addressing is quite difficult — I’m hoping this book improves my ability to make these trade-offs correctly.

Release 7.5.0 adds Queued Writes. This is the first time rqlite allows users to trade-off durability for much higher write performance.

rqlite is a lightweight, open-source, distributed relational database written in Go, which uses SQLite as its storage engine.
Nienke Eijsvogel, Ruben van Baarle and Daan de Graaf recently ran Jepsen-style testing of rqlite. Their tests showed that rqlite maintains linearizability of record insertion and modification, provided strong read consistency is enabled. Check out the full results on GitHub.
I recently had the opportunity to talk distributed systems and rqlite at the Hacker Nights NYC Meetup. It was great chance to speak with some folks, and discuss rqlite, its design, and how it operates.
The presentation is available, as is a video recording of the talk.
