Includes a practical setup guide using Conda and WSL2, plus hands-on code examples for creating a local Spark session, building DataFrames from inline data and CSV files, and performing column transformations. The lazy execution model is explained with a concrete 10-million-record scenario showing how Spark's predicate pushdown optimization avoids unnecessary computation. ## Full article daily.dev links to this article rather than hosting it.
