What is ClickHouse®?

ClickHouse is a highly scalable open source database management system (DBMS) designed for online analytical processing (OLAP). It uses a column-oriented structure and is praised for its exceptionally high performance, which comes from factors such as data compression, the vector computation engine, and the use of physical sparse indices. ClickHouse supports distributed query processing, partitioning, data replication, and sharding, making it ideal for applications working with massive structured data sets like data analytics, complex data reports, and data science computations. It is designed to handle terabytes of data and can return processed results in real time in a fraction of a second.
