ClickHouse

ClickHouse is an open source column-oriented database management system designed for online analytical processing (OLAP) queries. Originally developed at Yandex in 2016 for web analytics workloads, the project was spun out into an independent company called ClickHouse Inc. in 2021, now headquartered in Amsterdam, the Netherlands. ClickHouse has become one of the fastest-growing open source databases in the world, renowned for its extraordinary query performance on large-scale analytical datasets.

The database excels at processing billions of rows and terabytes of data in real time, using advanced compression algorithms and vectorized query execution to deliver sub-second analytics. It supports a rich SQL dialect, materialized views for pre-aggregated queries, distributed query processing across clusters, and seamless data integration from numerous sources. ClickHouse Cloud provides a fully managed serverless offering that eliminates operational overhead while preserving the raw performance of the open source engine.

With its European headquarters in Amsterdam and a global team of engineers, ClickHouse serves thousands of organizations from startups to Fortune 500 companies processing trillions of rows daily. The company maintains SOC 2 compliance and offers GDPR-compliant data processing with data center options in the EU and US. For organizations seeking a high-performance, open source alternative to proprietary cloud data warehouses like Snowflake, ClickHouse delivers unmatched analytical speed with full data sovereignty options.
