Apache Spark is amazing when everything clicks. But if you haven’t seen the performance improvements you expected, or still don’t feel confident enough to use Spark in production, this practical book is for you. Authors Holden Karau and Rachel Warren demonstrate performance optimizations to help your Spark queries run faster and handle larger data sizes, while using fewer resources.
Ideal for software engineers, data engineers, developers, and system administrators working with large-scale data applications, this book describes techniques that can reduce data infrastructure costs and developer hours. Not only will you gain a more comprehensive understanding of Spark, you’ll also learn how to make it sing.
With this book, you’ll explore:
How Spark SQL’s new interfaces improve performance over SQL’s RDD data structure
The choice between data joins in Core Spark and Spark SQL
Techniques for getting the most out of standard RDD transformations
How to work around performance issues in Spark’s key/value pair paradigm
Writing high-performance Spark code without Scala or the JVM
How to test for functionality and performance when applying suggested improvements
