Welcome to ClickHouse, @andy_pavlo 👋

We're launching ClickHouse Labs, a new research group advancing foundational database technology, led by Andy as VP of Database Research.

Andy is an award-winning database researcher, professor at Carnegie Mellon University’s Computer Science Department and longtime leader of the CMU Database Research Group. At ClickHouse Labs, he'll build a team to take on the hardest problems in database systems, testing their work on real workloads and publishing it in the open, across both ClickHouse and PostgreSQL.

Couldn't make the 26.10 release call? Don't worry, you can still watch Alexey Milovidov train an XGBoost model on a million rows in about five seconds, then use it to make predictions in SQL.

Plus 103 other new features.

Free software doesn’t mean free infrastructure.

ClickHouse co-founder Yury Izrailevsky explains how separating compute and storage changes the cost equation, and why managed cloud can cost less than self-managed open source.

Shipsidekick finally had enough of Neon’s constant outages and slow support. Since moving to @ClickHouseDB Managed Postgres in a single weekend, CPU usage has dropped from 100% to 5-10%, cache hit rate is up from 30-35% to 99%, and queries run ~10x faster.

So exciting to see the power of WalShadow in action! Literally fusing Postgres and ClickHouse together.

The past month has been intense, rigorous POCs, lots of testing, and a few early production customers! The results have been incredibly promising. 🚀

We’re seeing WalShadow B/s from Postgres to ClickHouse with sub-second latency. Something that was previously impossible to achieve!

Here’s one from Anirudh at @physical_int, 350ms vs. 35 seconds! 🤯

A little bittersweet seeing the comparison with PeerDB, but always wanted to do, take Postgres to ClickHouse replication to the next level.

Huge thank you to Anirudh, @mairbek and the Physical Intelligence team for their support since the beginnning. It means a lot to us! ❤️

Stay tuned for more stories. We’re just getting started! 🔥

Guillermo Rauch (@rauchg) explains how Vercel thinks about ClickHouse as part of its data infrastructure, and why agent-era applications need fast, direct access to data.

@ApacheParquet @ApacheIceberg A bit of overtime Q&A

and that's a wrap.

Try 26.10 and tell us what is amazing.
Then tell us what is terrible and we will make it amazing.
