A Tale of Four Fuzzers:
Some time ago, we overhauled TigerBeetle’s routing algorithm to better handle varying network topologies in a cluster
And ended up adding not one, not even two, but four very different new fuzzers to the system!

PGlite v0.4 is out 🚀
PostGIS, connection multiplexing, and a major architecture refactor - bringing embedded Postgres closer to native.
Now at 13M+ weekly downloads and showing up everywhere from CI to browser-based dev environments.

A historic step for profiling within the OpenTelemetry project!
StreamDB - a reactive database in a Durable Stream, designed for AI apps and agentic session state.
You give it a Standard Schema. You get type-safe, multiplexed data sync into TanStack DB:

Tigris is announcing CougarLLM - the world’s first "truly global" inference server: www.tigrisdata.com/blog/cougarl...
One endpoint, zero configuration, and zero egress fees. It’s designed so that even your fallback region has a fallback region.
TigerBeetle 0.16.75 is released!
- Use transparent huge pages on Linux for a small performance boost.
- Fix a fast path optimisation which wasn't being taken.

Jens @axboe.bsky.social put Linux in the fast lane with io_uring.
His son Jonas takes the need for speed to the track.
And TigerBeetle is proud to partner.
Catch Jonas at Sebring this weekend for the Radical Cup North America season opener!
I'm happy to share that I will be speaking at #QConLondon on March 16 on deterministic simulation testing at Polar Signals. For anyone interested in attending: SPEAKER60QUK26 for £60 off
Our engineering team is cooking 🍳 and sharing great tidbits recently that you might have missed 🧵
January in TigerLand is out!
- Improved performance, simplified interfaces
- A blog post about bitemporality
- Solving the "hot key" problem

Neoclouds are challenging hyperscalers with a distributed computing architecture-modeled storage layer that supports computing across any cloud.
Thanks to @tigrisdata.com
In other parts of security, we’ve learned that fixing classes of problems is the only way we can address them for good — but we haven’t had that mindset shift yet in access management.
We need better controls, so that we can get to fewer tickets, not faster tickets.

TigerBeetle 0.16.72 is released!
- Dramatically improve view change time
- Add support for rotating the AOF
- Various documentation improvements

If you're a developer, you live in the command line. Tigris' new CLI lets you supercharge your shell with bucket forking, object management, and more all from one easy to use program. It's just an npm install away:
npm install -g @tigrisdata/cli
AI makes code cheap. The scarce asset is now the system's self-knowledge.
Specs and contracts were always valuable—but too expensive to maintain. So we invested sparingly, specs drifted, and we read the code instead.
That calculus has flipped with coding agents.

TigerStyle.dev
A new, visual home for TigerStyle -- the software engineering methodology developed by TigerBeetle to produce safer, faster software in less time.
"Do the hard thing today to make tomorrow easy."
"If you want to be remembered, be remarkable."
We've been working on something exciting in the Arrow/DataFusion ecosystem, which finally shipped with yesterday's release of DataFusion. You can now use Run-End-Encoded arrays in group by clauses!

What a year!
From $25M funding to Git-like bucket forks, our 2025 was all about powering modern AI workflows with fast, flexible object storage.
Catch the highlights! 👇
My EuroRust talk has been uploaded to YT! I cover how we architected our Rust database at @polarsignals.com as a set of state machines to enable deterministic simulation testing and catch hard-to-reproduce bugs before they hit prod.
What an awesome year at Polar Signals! Some highlights:
📈 >10x data scale
⚡️ Shipped always-on GPU profiling
🦀 Shipped our new Rust/DataFusion/Vortex DB
Feeling lucky to get to work with such an incredible team & customers like Vercel, Notion, Canonical, Turbopuffer and more!
2026, we're ready!
A simple 50-line code change saves us 30% of CPU across our whole infrastructure. This is the magic of system-wide profiling with @polarsignals.com. Easy to spot, easy to fix.
🚀 We recently announced our NVIDIA CUDA always-on profiler. Check out this blog on how to try it out super quickly with your CUDA workload today!🧊

Today we're open-sourcing Durable Streams: a persistent stream primitive and HTTP protocol for reliable, resumable, real-time data streaming to clients.
We built it inside Electric. Now we're standardizing it as a standalone protocol.
We completed a major project to switch our storage file format from Parquet to Vortex 🌪️ resulting in 70% average query performance improvement across the board 🚀
Learn more about how rethinking interface-imposed limitations unlocked these gains in our latest blog post 👇
Awesome intro to Sync Conf from @thruflo.com, asking the question where sync fits in this fast changing world of AI.
Sync, as it happens, is a key component to this bright future!
"If you can't count correctly with contention at high speed, it's not OLTP. And if you're not doing serializable, if you're cutting corners on isolation, it's not ACID."

Aaron Francis captured it perfectly on Database School: with Tigris, ‘the region is just Earth.’
No CDNs, no cross-region replication, no complex DR— Reliability is the default on Tigris.
