Why is ClickHouse so fast?
Column-oriented databases are better suited to OLAP scenarios. They are at least 100x faster in processing most queries. ClickHouse uses all available system resources to their full potential to process each analytical query as fast as possible.
Column-oriented databases
In column-oriented databases, like ClickHouse, data is stored in columns, with values from the same columns stored together.
Row-oriented databases
In row-oriented databases, data is stored in rows, with all the values related to a row physically stored next to each other.
Deploy your way
Unlike traditional closed-source databases, ClickHouse runs in every environment, whether it’s on your machine or in the cloud.
ClickHouse Cloud
The best way to use ClickHouse. Available on AWS, GCP, Azure and, on their respective marketplaces.

ClickHouse is faster than most traditional data warehouses and databases and is most often used when real-time queries on large datasets are necessary at an affordable cost. However, developers also often use ClickHouse on top of their CDWH or OLTP databases to act as a “speed layer” within their existing infrastructure.
OLAP stands for “online analytical processing” which contrasts from OLTP, or “online transaction processing.” As the name suggests, OLAP databases perform significantly better compared to OLTP databases for analytical workloads common with large datasets.
In order to easily process large amounts of data, ClickHouse uses highly optimized compression techniques and vectorized query execution to maximize CPU efficiency.
ClickHouse supports connectors to many clients and drivers, including common BI and data analysis tools. Please see this page for a complete list of supported integrations.
Self-managed ClickHouse is dependent on the cost of your compute and data storage resources, as well as headcount necessary to manage the ClickHouse deployment. For the most affordable way to run ClickHouse, use ClickHouse Cloud, which starts at $50/month.
