ClickHouse is an open-source analytical database known for its speed, adopted by prominent companies such as Bloomberg, Cloudflare, eBay, Spotify, Uber, and CERN. It uses a columnar storage engine, which allows faster performance on analytical operations like AVG, DISTINCT, or MIN. The tutorial guides the reader through creating a dashboard on top of ClickHouse using Cube, an open-source analytical API platform. The author starts by running ClickHouse on various platforms, including macOS, Linux, AWS, GCP, and Yandex Cloud, before moving to building an analytical API with Cube.js. The author then explores data visualization options, including the Cube Developer Playground, which allows generating a schema, building queries, and visualizing results. Finally, the reader learns how to build a custom dashboard using React, ApexCharts, and Ant Design components to visualize stock market data from ClickHouse.
