Successful MySQL applications have a very common scale problem: how to provide analytics when data grows too large for MySQL to handle. Fortunately, there is a good answer. ClickHouse is a popular, open source column store you can use to add fast analytics to MySQL applications. We'll start with an introduction to ClickHouse for MySQL users showing familiar SQL syntax and table engine design. We'll then walk through important features like support for MySQL wire protocol, ability to read data directly from MySQL tables, and different ways to move data from MySQL into ClickHouse. Finally, we'll touch on design approaches that allow you to extend MySQL applications with analytics that can handle billions of rows.

ClickHouse is famous for speed. That said, you can almost always make it faster! This webinar uses examples to teach you how to deduce what queries are actually doing by reading the system log and system tables. We'll then explore standard ways to increase query speed: data types and encodings, filtering, join reordering, skip indexes, materialized views, session parameters, to name just a few. In each case we'll circle back to query plans and system metrics to demonstrate changes in ClickHouse behavior that explain the boost in performance. We hope you'll enjoy the first step to becoming a ClickHouse performance guru!
