The book describes the emergence of big data technologies and the role of Spark in the entire big data stack. It compares
Spark and Hadoop and identifies the shortcomings of Hadoop that have been overcome by Spark. The book mainly focuses on the
in-depth architecture of Spark and our understanding of Spark RDDs and how RDD complements big data's immutable nature, and
solves it with lazy evaluation, cacheable and type inference. It also addresses advanced topics in Spark, starting with the
basics of Scala and the core Spark framework, and exploring Spark data frames, machine learning using Mllib, graph analytics
using Graph X and real-time processing with Apache Kafka, AWS Kenisis, and Azure Event Hub. It then goes on to investigate
Spark using PySpark and R. Focusing on the current big data stack, the book examines the interaction with current big data
tools, with Spark being the core processing layer for all types of data.
The book is intended for data
engineers and scientists working on massive datasets and big data technologies in the cloud. In addition to industry professionals,
it is helpful for aspiring data processing professionals and students working in big data processing and cloud computing environments.
