  摘要:ClickHouse is an open source analytical database management system with SQL support. It is capable of storing tens of petabytes of data and processing billions of rows per second per server to provide analytical reports with subsecond latencies, all while ingesting new data in real-time. ClickHouse was originally built by Yandex and nowadays it is used by hundreds of companies including Tencent, Sina, TouTiao, Huya, KuaiShou, Qingyun and CloudFlare. In this lecture, we will first give an overview of what ClickHouse is, how it works and how with iterative approach to organizing data storage it resulted to be a powerful and extremely fast open source system. Then we will present a subset of the most notable ClickHouse features introduced recently, such as data skipping indices, custom compression codecs, sampling profiler on the query level and z-curve indexing, etc. Finally, we will talk about ClickHouse internal design and unique implementation details that allow us to achieve the maximum performance of query processing and data storage efficiency.
