ClickHouse is an open source column-oriented database built for online analytical processing. It is designed to run aggregate queries over very large tables quickly, which is the workload behind observability, real-time analytics, business intelligence and event data platforms.
Its speed comes from architectural choices rather than tuning. Storing data by column instead of by row means a query touches only the columns it needs; heavy compression reduces the volume read from disk; and vectorised execution processes data in batches rather than row by row. The result is that queries scanning billions of rows can return in a form fast enough to sit behind an interactive dashboard, which is not usually true of general-purpose relational databases.
The technology originated at Yandex as an internal analytics engine and was released as open source before a company was formed around it. ClickHouse Inc. now develops the database and operates ClickHouse Cloud, a managed service, while the core remains open source with an active community. The company is distributed across multiple countries and hires remotely, with concentrations of staff in the United States and Europe.
