Imagine you're working with a third-party library that provides a User class. You need to add JSON serialization to it, but you can't modify the source code. Of course you can create a wrapper class or extend it, but that feels clunky and breaks existing code that expects the original type. This is where type classes shine. They're one of Scala's most powerful patterns, and they're the secret ingredient in popular libraries like Cats, Scalaz, and Circe.

The spark-sql-perf toolkit doesn't work for Spark 4.0+ currently, and this guide shows you how to get it running(with a custom patch). While many developers have their own complex Spark setup, this workflow is designed to be simple and reproducible. It only requires an AWS account to provision a cluster and run a full benchmark from scratch. We'll focus on the patch, the build process, and how a tool like FlintRock makes deploying custom Spark clusters incredibly simple.
