That's me. From being an ML Engineer to contributing to a DB project. Never imagined this timeline but here we go.

Build @measure_sh as an open source mobile app monitoring platform. Use @ApacheIggy for ingesting crazy amounts of mobile telemetry data. Run into issues. Iggy maintainer drops into our repo. Stress tests 3 million events. Tells us how to improve perf. Open source is ❤️

Everywhere I go, people keep commenting on how wild it is that I have something working with us straight from *prison*. Well, no longer. Tomorrow, at 8 am in the morning, @PThorpe92 is a free man. Preston is an inspiration to us all. He achieved so much from behind bars. I am sure he will go even higher as a free man.

I'm extremely happy to announce that this year I'll have the chance to speak at the top-tier, performance-oriented #P99CONF 🚀
We've been working hard behind the scenes to bring you an unforgettable P99CONF 2026. Registration is now open, so take a look at who is coming back and the new speakers we have on board > p99conf.io/2026/04/01/be-par… #ScyllaDB #P99CONF

Same. Anyone in the DB space who might be looking to bring on an entry level DBMS developer with real open source experience on a greenfield DB, @pavan4820 is by far one of our most valuable contributors and has got us for thousands of dollars in rewards from the turso bug bounty
I'm so happy to have people like @pavan4820 contributing to Turso. You can help build an alternative to SQLite while still making SQLite better. That's what a good open source citizen does. Great work!

I wrote a little bit about how I've been designing my engine with zero-copy page access. Two problems to solve: - Copy at the OS boundary - Fresh copies from buffer pool into higher layers Thank you to @EigenVectorizer and @debasishg for reviewing a draft.
Restructured the query engine so that it's easier to do optimizations moving forward. Alex Chi's blog post was very helpful here. Turns out that following the standard Cascade style approach doesn't work so well in Rust.

92% improvement in P9999 latency. 4 GB/s consumer throughput. One node. 🚀 How? By building @ApacheIggy entirely in Rust. Join @EigenVectorizer from @laserdatainc at #RustIndia2026 for a deep dive into: ✅ Why they swapped tokio_rs for io_uring ✅ Zero-copy serialization strategies ✅ Handling RefCell hurdles in async Rust ✅ The move to Viewstamped Replication (VSR) The schedule is officially LIVE!

Compiler is correct 99.99% of the every time.
Watching codex slowly learn that it's never a compiler bug is the most human thing I have seen all week.

Thread-per-core io_uring? See how we moved Apache Iggy from Tokio's work-stealing to a shared-nothing* architecture to make the most out of modern hardware and provide ultra-low, predictable tail latencies. iggy.apache.org/blogs/2026/0… #io_uring #iggy #rust #streaming #apache #asf

Trying to squeeze 5GB/s from localhost has turned into a deep learning exercise. The best I'm getting is 1.5GB/s.

Performance Hints Over the years, my colleague Sanjay Ghemawat and I have done a fair bit of diving into performance tuning of various pieces of code. We wrote an internal Performance Hints document a couple of years ago as a way of identifying some general principles and we've recently published a version of it externally. We'd love any feedback you might have! Read the full doc at: abseil.io/fast/hints.html

The lack of "feature design" is why so many products over time feel hollow or messy. This isn't visual design. This isn't architectural design. I thought that a short video lecture of what feature design is and a real case study of applying it in Ghostty would be helpful. Feature design is the planning step behind how you're going to solve one or more user problems with a product feature: what that feature looks like, how it feels, and not just how its going to tactically solve these specific problems, but how that solution is going to interface with the edges of other features that currently exist or are planned to exist in the future.

Why you might want to consider the completion-based I/O (io_uring) for your next project. Check this discussion (a glimpse of the future blog post). reddit.com/r/rust/comments/1… #iggy #rust #io_uring #compio #tokio #apache #asf
