We'll cover data insertion, aggregation, joins, and distributed queries. You'll learn about the basic flow of query execution, how ClickHouse parallelizes processing, and how it uses memory. We'll also show you standard tools like the system.query_log table that help you diagnose problems, trace distributed queries, and track memory usage.
