This week we announced the largest expansion of ClickHouse since we launched ClickHouse Cloud, and we’re welcoming the @xata.io team to ClickHouse.
ClickHouse now serves more than 5,000 customers, including DoorDash, Ramp, Meta, Tesla, Cisco, and Visa.

Another database business question is whether an ISV should start with an OLAP DBMS then add OLTP, or start with an OLTP DBMS then add OLAP.
‣ ClickHouse, Snowflake, Databricks are doing OLAP→OLTP.
‣ Supabase, MongoDB, PlanetScale(?) are doing OLTP→OLAP.

There are more historical examples of OLTP→OLAP (Oracle, Actian, Sybase, Informix, Couchbase), but that's because the OLTP DBMS market is much older (+50yrs) than the OLAP DBMS market (+30yrs).

Most of ClickHouse's Postgres customers are migrating from existing databases. They already use the ClickHouse DBMS, so running their Postgres instances on the same platform makes it easier to get data into the OLAP engine.

I wrote a new first-year undergraduate course on databases (focussed on how to use query languages, not on DBMS internals). It covers SQL, relational algebra, JSON documents, Cypher, and Datalog. Notes are freely available here: www.cl.cam.ac.uk/teaching/262...

We are now at a point where AI agents have become the best tools for selling and understanding what ontologies are all about.
The LLM Wiki, second brains, and increasingly, context engines are helping people understand the vision behind the Semantic Web. Here are some examples of how these ideas come together by harnessing hyperlinks through our Virtuoso platform—a combination of a multimodel DBMS and an HTTP data spaces server.

I don't think I'd add any more languages. The next thing I'd go into if I had time was how a DBMS actually stores and queries data.

A month after porting Greenplum to PostgreSQL 19, pg_vexec beats ClickHouse on Parquet and nearly catches up on MergeTree in ClickBench, and a rough draft of a GPU version is faster still. I’ve published the telemetry from the runs: charts, metrics, DBMS logs and numbers from deep inside the engin
