Open source as stained glass

Celebrating 10 years of ClickHouse open source through the lens of a stained glass window. We query ClickHouse's own history live, from commit curves to the system.contributors table.

Celebrating 10 years of ClickHouse open source through the lens of a stained glass window: thousands of contributors, one thing the world runs. We query ClickHouse's own history live, from commit curves to the system.contributors table that ships inside every build, with a real cBioPortal example from Memorial Sloan Kettering.

This is an Open House 2026 session. https://clickhouse.com/openhouse/san-francisco
