Observability for the age of agents: How Vercel uses ClickHouse

Dom Busser and Vincent Voyer explain how Vercel uses ClickHouse Cloud to ingest 100 billion log events a day, serve customer-facing observability, and support agents querying data with SQL.

Vercel makes real-time observability available directly to its customers. Data needs to be queryable within a second of ingestion, with fast queries even months later.

Dom Busser, Director of Engineering, and Vincent Voyer, Member of Technical Staff at Vercel, explain how they built a custom ingestion path into ClickHouse Cloud, handle 100 billion log events a day, and keep multi-tenant queries fast and safe. They also show how agents are changing observability: querying data with SQL on demand instead of relying only on fixed dashboards.
