Now that we have had a basic overview of the architecture of Spark and key software components, we will cover Spark RDD's in this chapter. During the course of this chapter, we'll walk through the following topics:

How to construct RDDs
Operations on RDDs, such as transformations and actions
Passing functions to Spark (Scala, Java, and Python)
Transformations such as map, filter, flatMap, and sample
Set operations such as distinct, intersection, and union
Actions such as reduce, collect, count, take, and first
PairRDDs
Shared and broadcast variables

Let's get cracking!
