Frequently it is said, “Graphs can do anything,” or at least, “There are a bunch of different things you can do with graphs.” That says nothing, of course, so in this book we show a number of specific, real-life ways you can apply graphs and talk about how to implement such solutions in Spark GraphX.

A lot of technology buzzwords are applicable to this book: Big Data, Hadoop, Spark, graphs, machine learning, Scala, and functional programming. We break it all down for you. Even though we end up in some fairly advanced areas, we don’t assume anything ...
