Chapter 3 Overview :-
This chapter is your hands-on guide to getting started with Apache Spark. It begins by introducing the core tools for interactive data exploration, focusing on the Spark Shell for quick prototyping in both Scala and PySpark. You'll write and run your first Spark applications, learning the basic syntax and concepts that underpin all Spark jobs.
Next, the chapter moves from simple examples to practical, business-oriented analytics. You'll use Spark to answer common business intelligence questions, such as calculating Daily Active Users (DAU) and analyzing average cart size. The chapter also covers foundational text analytics, showing you how to process and derive insights from raw text data, including the classic WordCount example.
Finally, you'll go behind the scenes to understand how Spark executes your code. The chapter breaks down Spark's execution model, explaining the relationship between Jobs, Stages, and Tasks, giving you a deeper appreciation for how Spark efficiently processes data under the hood. By the end of this chapter, you'll have the foundational skills to write, run, and understand your first real-world Spark applications.
