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.

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 As always, we finish with recommending some reading materials!

@ApacheParquet @ApacheIceberg Also, if you would rather we run ClickHouse for you instead of running it on your own....there are a number of new amazing features on ClickHouse Cloud.

@ApacheParquet @ApacheIceberg We are officially out of time? But how do you ignore the integrations!

@ApacheParquet @ApacheIceberg Related, do you love using PromQL?

Maybe you can just use ClickHouse as Prometheus? ;)

@ApacheParquet @ApacheIceberg What else is new in our support for @ApacheIceberg

Parquet VARIANT support, and a new implementation of the unity catalog type.

But that's not all, ClickHouse now applies deletion vectors when reading.

@ApacheParquet @ApacheIceberg We continue with some features for data lakes.

As a 'native' option, you can use the type: s3_plain_rewritable

@ApacheParquet @ApacheIceberg Integration with Elasticsearch as a table engine and a table function?

You can read documents from an index as a JSON column. Read-only...for now.

@ApacheParquet @ApacheIceberg We aren't stopping there.

A new query language for logs! LogsQL (the log query language of VictoriaLogs)

@ApacheParquet @ApacheIceberg Alexey is now live-demoing usage of XGBoost dictionaries (train a gradient-boosted model at dictionary load)

@ApacheParquet @ApacheIceberg We are adding a new cache type in ClickHouse!

@ApacheParquet @ApacheIceberg Pushing the boundaries requires building experimental features.

This talk is about to get very good.

@ApacheParquet @ApacheIceberg SQLite was already supported as a database engine, the ability to attach a table, and use a table function. This has existed for 5 years.

In 26.10 you can now use SQLite as a data format as well.

@ApacheParquet @ApacheIceberg Are you aware that ClickHouse supports recursive CTE?
We also have Materalized CTE.

Now you can nest them.

Super useful for graph traversal and tree structure traversal.

@ApacheParquet @ApacheIceberg Query cache can now keep its entries in a filesystem cache!

@ApacheParquet @ApacheIceberg And now onto "something interesting" (as if everything before wasn't already)

@ApacheParquet @ApacheIceberg Even more improvements for @ApacheParquet !

@ApacheParquet @ApacheIceberg This is one of Alexey's favourite optimizations.

So I'm not going to try and give commentary...You should watch it live.

A similar optimization now exists for @ApacheParquet and @ApacheIceberg

(also hdfs ;) )

This feature is even less easy to explain than many others...but we've use 2x less memory for hash tables (useful with GROUP BY and uniqExact)

The query condition cache now supports now() filters!

Now there is a table function for data obfuscation!

(and yes, a live demo)

Are you quantizing for vector search? We've added another tool to your toolbox.

IPCrypt in your queries?

Oh. Indeed.

We start, as always, with small and nice features.

Kicking off with syntactic sugar via a function composition operator.

It's a record breaking release!

104 new features
225 performance optimizations
739 fixes

We are live with the 26.10 ClickHouse Release call!

@ceo_clickhouse Fireside chat: youtube.com/watch?v=_8DUJK…

AI agents are putting new pressure on the data layer. They need fast, scalable infrastructure they can query efficiently.

Open ecosystems matter. And infrastructure has to keep pace with the way software is being built.

Full fireside chat with Aaron Katz (@ceo_clickhouse), g), Tristan Handy (@jthandy), and Lukas Biewald (@l2k) in the comments.

Aaron Katz (@ceo_clickhouse) sat down with Harry Stebbings (@HarryStebbings) of 20VC to answer a simple question: why ClickHouse?

Harry points to a shift already underway: agentic applications are driving more queries, more real-time workloads, and higher expectations for speed real-time data infrastructure matters.

Visa turned multi-day reporting into answers in seconds with ClickHouse Cloud and LibreChat, so teams can ask questions in plain English while Cloud handles scaling.
