Hi fellow rust devs, I'm Tyson, I currently work at ThoughtWorks as a software engineer.
After 3 years of hard work, Celeriant, my open source event store, goes public. It's gone from a scrappy C# backend on a side project to a serious 150K-line distributed database in Rust.
It was tough to get good at Rust and I ended up re-writing the whole thing 7 times over. But it made me a better engineer, no more hiding behind the garbage collector. And I had a lot fun setting up a home lab with rpi5's and running chaos tests on it.
At this year's p99-conf I'll present how Celeriant hits 1 million durable, replicated writes/sec on AWS i4i.metal, and why the CPU is the bottleneck, not the NVMes. It's free and virtual, so sign up for it!
And at XConf Singapore I'll be talking about why Claude Code doesn't touch my inner development loop; how code is the design; and how we can still use LLMs to build great, high quality software (hint: its verification!).
Docker image is up. If event sourcing is your thing and you want to experiment, you can get it running in under 5 minutes. C# and Rust clients only at the moment.
It's been a massive job and really challenged me as a software engineer. Would I do it again? Not without my wife's permission :)
Celeriant is inspired by ScyllaDB's seastar thread-per-core model, and built on Glauber Costa's Glommio library. A group of us have forked it out of datadog and are now maintaining it. Get into it and build something cool on io_uring!

thanks to the r/rust community for the many great posts and links which helped me get up to speed with the rust ecosystem over the years! Been a bit noisy recently but still good to see more interest in Rust and building things with it.
