Analyzing Access Logs for Load Testing. Tips and Tricks for Cats

Continuation of the talk “Load testing for cats. Scenario- vs Hit-Based Approaches”. This time I will reveal the way we at Ozon analyze incoming traffic to the site to determine which queries we can use in load testing, and which ones we need to put in the scripting part. To do this, you and I will make a small pet project in Go using ClickHouse and regular expressions. You will learn how this methodology evolved, what tools we used and use, and how you can easily take the same into your project.
