Scala Programming for Big Data Analytics
Gain the key language concepts and programming techniques of Scala in the context of big data analytics and Apache Spark. The book begins by introducing you to Scala and establishes a firm contextual understanding of why you should learn this language, how it stands in comparison to Java, and how Scala is related to Apache Spark for big data analytics. Next, you’ll set up the Scala environment ready for examining your first Scala programs. This is followed by sections on Scala fundamentals including mutable/immutable variables, the type hierarchy system, control flow expressions and code blocks. The author discusses functions at length and highlights a number of associated concepts such as functional programming and anonymous functions. The book then delves deeper into Scala’s powerful collections system because many of Apache Spark’s APIs bear a strong resemblance to Scala collections. Along the way you’ll see thedevelopment life cycle of a Scala program. This involves compiling and building programs using the industry-standard Scala Build Tool (SBT). You’ll cover guidelines related to dependency management using SBT as this is critical for building large Apache Spark applications. Scala Programming for Big Data Analytics concludes by demonstrating how you can make use of the concepts to write programs that run on the Apache Spark framework. These programs will provide distributed and parallel computing, which is critical for big data analytics. What You Will Learn See the fundamentals of Scala as a general-purpose programming language Understand functional programming and object-oriented programming constructs in Scala Use Scala collections and functions Develop, package and run Apache Spark applications for big data analytics Who ThisBook Is For Data scientists, data analysts and data engineers who intend to use Apache Spark for large-scale analytics. /div

Harness the power of Scala to program Spark and analyze tonnes of data in the blink of an eye! About This Book Learn Scala's sophisticated type system that combines Functional Programming and object-oriented concepts Work on a wide array of applications, from simple batch jobs to stream processing and machine learning Explore the most common as well as some complex use-cases to perform large-scale data analysis with Spark Who This Book Is For Anyone who wishes to learn how to perform data analysis by harnessing the power of Spark will find this book extremely useful. No knowledge of Spark or Scala is assumed, although prior programming experience (especially with other JVM languages) will be useful to pick up concepts quicker. What You Will Learn Understand object-oriented & functional programming concepts of Scala In-depth understanding of Scala collection APIs Work with RDD and DataFrame to learn Spark's core abstractions Analysing structured and unstructured data using SparkSQL and GraphX Scalable and fault-tolerant streaming application development using Spark structured streaming Learn machine-learning best practices for classification, regression, dimensionality reduction, and recommendation system to build predictive models with widely used algorithms in Spark MLlib & ML Build clustering models to cluster a vast amount of data Understand tuning, debugging, and monitoring Spark applications Deploy Spark applications on real clusters in Standalone, Mesos, and YARN In Detail Scala has been observing wide adoption over the past few years, especially in the field of data science and analytics. Spark, built on Scala, has gained a lot of recognition and is being used widely in productions. Thus, if you want to leverage the power of Scala and Spark to make sense of big data, this book is for you. The first part introduces you to Scala, helping you understand the object-oriented and functional programming concepts needed for Spark application development. It then moves on to Spark to cover the basic abstractions using RDD and DataFrame. This will help you develop scalable and fault-tolerant streaming applications by analyzing structured and unstructured data using SparkSQL, GraphX, and Spark structured streaming. Finally, the book moves on to some advanced topics, such as monitoring, configuration, debugging, testing, and deployment. You will also learn how to develop Spark applications using SparkR and PySpark APIs, interactive data analytics using Zeppelin, and in-memory data processing with Alluxio. By the end of this book, you will have a thorough understanding of Spark, and you will be able to perform full-stack data analytics with a feel that no amount of data is too big. Style and approach Filled with practical examples and use cases, this book will hot only help you get up and running with Spark, but will also take you farther down the road to becoming a data scientist.

The exponential rise of data in the modern digital era has been responsible for a transformation in the way that individuals, corporations, and governments conduct their operations. Every single click on the internet, every single transaction at a store, every single sensor in a machine, and every single post on social media all add to the massive amount of data that is known as Big Data, which is continuing to grow at an exponential rate. The tools and methods that have been used traditionally for data processing are no longer enough to effectively manage, process, or derive useful insights from the flood of information that is currently available. Big Data Analytics is a multidisciplinary area that integrates computer science, statistics, mathematics, and domain expertise in order to analyse and interpret vast and complex information. This has led to the birth of Big Data Analytics. In general, Big Data may be characterised by five fundamental aspects, which are sometimes referred to as the 5Vs. Volume refers to the volume of data that is produced each and every second. The rate at which information is generated and processed is referred to as velocity. A variety of data forms and kinds, including structured, semi-structured, and unstructured data, are referred to as variety. The trustworthiness and precision of the data is referred to as veracity. Value is defined as the possible advantages and insights that may be generated from data. The act of analysing these enormous databases in order to unearth previously concealed patterns, correlations, trends, and other important information is referred to as Big Data Analytics. With its help, businesses are able to make decisions based on data, improve the experiences of their customers, optimise their operations, and acquire a competitive advantage. It provides assistance for evidence-based approaches to the resolution of difficult issues in the realms of scientific research and public policy research. The capabilities of big data systems have been considerably improved as a result of the development of cutting-edge technologies such as distributed computing, cloud platforms, NoSQL databases, and real-time processing frameworks (such as Apache Hadoop and Apache Spark).
