ClickHouse is an open source high-performance column-oriented database management system that offers a user-friendly SQL query dialect with built-in analytics capabilities, and can generate custom data reports in real time. It processes billions of rows and dozens of gigabytes of data per server per second, working up to a thousand times faster than traditional approaches. ClickHouse is linearly scalable, hardware-efficient, fault-tolerant, and can be deployed across multiple data centers. Hundreds of companies across Europe, US, and China are adopting ClickHouse due to its benefits, which will be discussed at an upcoming meetup on October 5, 2017 in Berlin.
