Overview of this book

Apache Spark has seen an unprecedented growth in terms of its adoption over the last few years, mainly because of its speed, diversity and real-time data processing capabilities. It has quickly become the preferred choice of tool for many Big Data professionals looking to find quick insights from large chunks of data. This book introduces you to the Apache Spark framework, and familiarizes you with all the latest features and capabilities introduced in Spark 2. Starting with a detailed introduction to Spark’s architecture and the installation procedure, this book covers everything you need to know about the Spark framework in the most practical manner. You will learn how to perform the basic ETL activities using Spark, and work with different components of Spark such as Spark SQL, as well as the Dataset and DataFrame APIs for manipulating your data. Then, you will perform machine learning using Spark MLlib, as well as perform streaming analytics and graph processing using the Spark Streaming and GraphX modules respectively. The book also gives special emphasis on deploying your Spark models, and how they can be operated in a clustered mode. During the course of the book, you will come across implementations of different real-world use-cases and examples, giving you the hands-on knowledge you need to use Apache Spark in the best possible manner.

Chapter 4. Spark SQL

We've had a roller coaster ride so far. In the last chapter, we looked at performing ELT with Spark, and most importantly, loading and saving data from and to various data sources. We've looked at structured data streams and NoSQL databases, and during all that time we have tried to keep our attention on using RDDs to work with such data sources. We had slightly touched upon DataFrame and DataSet API, but refrained from going into too much detail around these topics, as we wanted to cover it in full detail in this chapter.

If you have a database background and are still trying to come to terms with RDD API, this is the chapter you'll love the most, as it essentially explains how you can use SQL to exploit the capabilities of the Spark framework.

In this chapter we will be covering the following key topics:

  • DataFrame API
  • DataSet API
  • Catalyst Optimizer
  • Spark Session
  • Manipulating Spark DataFrames
  • Working with Hive, Parquet files, and other databases
