A Day in the life of a ClickHouse Query is a gentle introduction to ClickHouse internals, focusing on topics that will help your applications run faster and more efficiently.

This webinar covers the basic flow of query execution and how ClickHouse handles aggregation and joins and distributes processing within a single CPU and across many nodes in the network. You'll also learn what happens inside ClickHouse when a query runs and find answers to questions like:

  • Why do queries run out of memory?
  • How can you make your queries even faster?
  • How should you size ClickHouse nodes for best cost-efficiency?
