ClickHouse
Fast open-source OLAP database for real-time analytics
A column-oriented database management system that enables real-time analytical reporting on large datasets using SQL queries with high performance and cost
Overview
ClickHouse is a fast open-source OLAP (online analytical processing) database management system designed for real-time analytics. It uses column-oriented data storage, which makes it significantly faster than traditional row-oriented databases for analytical workloads—at least 100 times faster in processing most queries.
The system leverages highly optimized compression techniques and vectorized query execution to maximize CPU efficiency, enabling analysis of billions of rows with millisecond results. ClickHouse is available in multiple deployment models: as a self-managed open-source installation, as a fully managed cloud service (ClickHouse Cloud) available on AWS, GCP, and Azure, or as a local version for querying files directly.
Designed for developers and enterprises, ClickHouse supports real-time analytics, observability, data warehousing, and machine learning workloads. It offers extensive integrations with BI tools, data visualization platforms, and other data ecosystem components, making it adaptable to existing infrastructure.
