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.

An agent needs SELECT, not your full account permissions. CREATE TOKEN in ClickHouse 26.9 lets you issue a time-limited, narrower credential without sharing your password.

@marcklingen sat down to demo all langfuse features in a single video.
Agent observability, monitoring, evals, prompt management, and what is special about Langfuse.
Great place to start if you are new, or catch up on latest changes.

The first database commits date to 2009. The server reached production in 2012, and the public release followed on 15 June 2016.

Great lineup for Rows & Columns (SF, Sept 22) -- the conference where data leaders discuss the "great convergence" of OLAP & OLTP 🔥
Excited to hear talks from @andy_pavlo, @nikitabase, @h_munzinger, @izrailevsky, and many others!

Sydney, we're coming to you 🇦🇺
ClickHouse is teaming up with Vercel for AI SYD on Thursday, October 8 at the AWS Sydney office, and the lightning talk lineup is a good one:
🔐 Patrick Collins (CEO, Dam Secure) planted real CVEs across 16 repos to find out which AI model actually catches vulnerabilities. Public benchmarks are saturated, so his team built their own eval suite from open-source commit history. The winning model? A surprise.
📊 Muhammad Ali (Senior Solution Architect, ClickHouse) presents "From Traces to Trust: Shipping Reliable LLM Apps with Langfuse." Building an LLM demo is easy; running one in production is not. Expect tracing for agent pipelines, evals that catch regressions before users do, and real traces from a live app.
Plus pizza and networking with Sydney's AI engineering community, from early-stage startups to global enterprises.
📅 Thursday, Oct 8 | 6:00–9:00 PM
📍 AWS Sydney, Level 37, 2/26 Park St
🎟️ Approval-based registration, request your spot: buff.ly/XhAT0tf

WalShadow is probably one of the most ambitious projects we’ve taken on.
When we decided to build this six months ago, we genuinely weren’t sure how it would pan out. We were going directly after Postgres’s physical write-ahead log, an area backed by decades of deep engineering expertise.
Now, seeing the early results with customers, especially Postgres → ClickHouse replication latency in the hundreds of milliseconds, it feels totally worth it. It opened up a new world tousers, that wasn’t possible before.
This wouldn’t have been possible without the team’s deep expertise in Postgres replication, the operational lessons we’ve learned onboarding thousands of customers to Postgres CDC, and our experience deep in the Postgres replication and backups, creating and contributing to WAL-G and WAL-RUS
I’m really excited for more customers to try it out.
And perhaps the most exciting part: this brings ClickHouse much closer to becoming a physical analytics standby for Postgres. 🚀 github.com/ClickHouse/walsha…

Is ClickHouse becoming a universal, multimodal DBMS? 🤔
Alexey Milovidov tackles that question in the 26.9 release call, which also covers incremental materialized views, PromQL, AI functions, and On-Demand Compute.
