Chapter 4. Transforming and Shaping Up Graphs to Your Needs

In this chapter, we will learn to transform graphs using different sets of operators. In particular, we will cover graph-specific operators that either change the properties of graph elements or modify the structure of graphs. In other words, all the operators that we use here are methods that are invoked on a graph and return a new graph. In addition, we will use join methods to combine graph data with other datasets. Using real-world datasets, you will understand when and how to:

• Use property operators to modify vertex or edge properties
• Use structural operators to modify the shape of a graph
• Join additional RDD collections with a property graph

Transforming the vertex and edge attributes ...
