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! github.com/apache/dataf...

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!🧊 www.polarsignals.com/blog/posts/2...

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." Full talk: youtu.be/yKgfk8lTQuE

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. Link to the full episode below 👇

TripleZip (YC W25), now processing commercial rent transactions with TigerBeetle. Congrats, Grayson and Yash, on going into production! We're cheering for you.

Vortex is incredibly exciting, we’ve already made plans months ago to make it the primary format we will be storing our data in on object storage! www.linuxfoundation.org/press/lf-ai-...

#SD25 online continues tomorrow! Join Cpt. @hannes.muehleisen.org for his talk on DuckLake Aug 4 at 10am PT / 1pm ET / 7pm CET www.youtube.com/watch?v=YQEU...

ElectricSQL recently completed a 120-day reliability sprint. Our one goal: make our sync engine so boring-reliable you stop thinking about it and just build. We chased every incident, fixed every user-reported bug, and made unglamorous work our priority. 🧵

TanStack DB is now in BETA! We’ve been working on TanStack DB, an embedded, reactive client database for TanStack Query, and are proud to announce today that with the 0.1 release that it's now in BETA! tanstack.com/blog/tanstac...

Tanstack DB is a reactive client store for building super fast apps on sync. Based on a TypeScript implementation of differential dataflow, it's type-safe, declarative, incrementally adoptable and insanely fast.

A much requested feature finally shipping! Now you can finally understand why your process is taken off the CPU, whether for timing reasons, for I/O reasons, or any of the many other possibilities!

Coming soon to a screen near you...

SD25 online starts next week! systemsdistributed.com/#agenda

🔥 Have you ever stared at a flame graph wondering why your app is slow? Using the new @PolarSignalsIO MCP, you can now ask "Why is my service slow?" and e.g. @anthropic.com's Claude Code or @cursor.com.web.brid.gy will analyze your production profiles and suggest code fixes.

📔Writing our Rust database from scratch gave us a golden opportunity to implement deterministic simulation testing as a core feature. Learn about the architecture that gives us full control over DST ingredients. 🧊 www.polarsignals.com/blog/posts/2...

The @tigerbeetle.com team runs a conference like they build their database — with artful craftsmanship, technical precision, and a sprinkle of magic. Kudos to an amazing SD ‘25 🤩⚡️

Tigerbeetle learns from history. While SQL is the language of databases for 5 decades, DebitCredit has been language of transactions for 5 centuries. Tailor interface for that. We can fit 8000+ transactions in 1mb, getting a lot more work done per network round-trip. #sd25

Our very own @asubiotto.bsky.social for the first time publicly talking about the DST approach we’re taking in our new database. (Blog post coming soon as well!)

Arrivals to Amsterdam for #systemsdistributed have begun, including the sun! We can't wait to welcome this year's SD participants in 3 days. Just a few tickets remain and we will close sales EOD today (Monday, June 16th).

PGlite can now be used with any Postgres client, and pairs perfectly with AI app builders for vibe coding. Love that with @bolt.new *everything* runs in the browser - node, the dev server, and now even PGlite 🚀🤯 Awesome job by the team to get this out!

We've been working hard to enhance our continuous profiling for GPUs. Learn about more metrics (like PCIe throughput) and the upcoming On-GPU profiles. If you are attending ai.engineer, come and stop by our booth S18 to discuss all of these features! www.polarsignals.com/blog/posts/2...

Working with several seed/series A infra startups (databases, storage, distributed systems, foundational AI infra) hiring across core engineering and GTM. Small teams (<20), high-agency IC roles. DM me if interested or you have referrals!

One month until Systems... Distributed!
