Combined with an async I/O stack built around io_uring, @tursodatabase flushes durability work without stalling writers. At #P99CONF, @Peristocles1 will share the architecture and what it did to their p99 write latency under concurrent load. ow.ly/ehiK50ZuJAi #ScyllaDB

We've patched Firecracker snapshots to support io_uring and O_DIRECT writes 🤭 Our sandboxes utilize around 2G of resident memory in the p90 case, due to deps like Vite, FFmpeg or Chromium. That's becoming less of a problem with these types of improvements! Feels good.

Companies that make it almost impossible to cancel deserve a special place in hell, and are guaranteed to never have return customers. Looking at @dish and @VivintHome What a nightmare...

What an epic day! Met Jonas @axboe in person and got to see him smash qualifying races. Unlucky collision in Race 1 (10s penalty for the culprit) but he still finished strong. Bring on the @RadicalMSport World Final tomorrow… 🔥 @TigerBeetleDB

.@TigerBeetleDB is built on a single-threaded, io_uring-based event loop. When they faced an object storage challenge, they built everything from the ground up in Zig. Learn how from @georg_kreuzmayr at our free and virtual #P99CONF: ow.ly/VRSS50ZFfQH #ScyllaDB

It's Friday, and that means time to post some crazy patches. Too much info to detail here, see: lore.kernel.org/io-uring/202… for making io_uring a lot savvier on handling kernel blocking, with some tasty results to go with it. In crappy looking graphs below.

Just back from @COTA where we wrapped up the 2026 national season with the Pro 1500 class win, the outright win over all classes, and helped the team secure the team championship as well. Could not have done it without @TigerBeetleDB by our side! Profile video worth a watch!
"Racing fits that need for more in me." – Jonas Axboe "Pushing it to the limit, that same champion spirit, but also that same humility, that he and his dad both have... it's a quiet ferociousness." – Joran Dirk Greef Congrats, Jonas @axboe, on winning the Radical Cup North America Pro 1500!

TIL: core data structure for how task works are handled in io_uring changed from linux lockless lists to lockless MPSC FIFO queues, to bring some fairness in how io_uring works .. slide from @axboe's presentation in SD 2026 - piped.video/y4cb39pBp0I?si=6BBy… also an LWN article on the related topic - lwn.net/Articles/1081871/

🏎️ At last year’s Systems Distributed conference in Amsterdam, @jorandirkgreef unveiled a virtual racetrack our team developed to show @TigerBeetleDB racing against a million dollar Postgres cluster. At this year's Systems Distributed we unveiled the real life TigerBeetle race car. The talented driver, @axboe's son Jonas, inspires us to be champion, to be fast and safe, to push the limits always. Watch Joran describe so masterfully what it means to be champion both on and off the race track. #bechampion #systemsdistributed
