It will then dive into explaining languages such as Java, Scala, Clojure, Kotlin, and Groovy and will show how to work with each language, their features, use cases, and pros and cons. With this book, you'll discover why Scala is ideal for highly scalable, component-based applications that support concurrency and distribution. 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. In this second edition, you will find an updated coverage of the Scala 2. This book will help you translate what you already know in Java to Scala to start your functional programming journey. Many Akka concepts, such as its actor-based system, are discussed thoroughly.
We'll show you how to build a cheap but effective cluster infrastructure with Apache Mesos. Both object-oriented and functional programming in Scala are discussed. I read it on the bus, at lunch etc. Let's begin this journey together, and I hope to see you there. Style and approach With the help of various industry examples, you will learn about the full stack of big data architecture, taking the important aspects in every technology. This book will get you up and running quickly by adopting a pragmatic approach with real-world code samples. Akka is a tool kit specializing in writing scalable applications that take full advantage of the modern multi-core processors.
Explore the concepts of functional programming, data streaming, and machine learning Author: Md. Description Description Why learn Scala? Together with its rich ecosystem of native libraries and an extremely simple and consistent functional approach to data manipulation, which maps closely to mathematical formula, it is an ideal, practical, and flexible language to meet a data scientist's diverse needs. The Java virtual machine is a mature and very versatile platform for running software that takes full advantage of modern hardware features. You'll start with Scala's core types and syntax before diving into higher-order functions and immutable data structures. This practical book provides a comprehensive yet approachable introduction to the language, complete with syntax diagrams, examples, and exercises. It will help you unlock the secrets of building your own up-to-date Scala application while maximizing performance and scalability.
Design patterns make developer's lives easier by helping them write great software that is easy to maintain, runs efficiently and is valuable to the company or people concerned. Then you'll get to know how to improve the data structure architecture and optimize resources using Apache Spark. After reading and using this tutorial, you'll come away with the skills in Scala to kick-start your productivity with this growing popular language. It also covers some useful patterns and idioms to use the techniques described. It will teach you the core benefits of Scala and the fundamentals of functional programming by developing a robust application. You don't need to be a data scientist or distributed computing expert to appreciate this object-oriented functional programming language. When is it a good time to use them? It will place special emphasis on functional language.
Some of the other concepts that are discussed include abstract classes, interfaces, arrays, and collections and exceptions. Thus, if you want to leverage the power of Scala and Spark to make sense of big data, this book is for you. This book also covers the most useful tools available in the Scala ecosystem, such as Slick, Play, and Akka, and a whole lot more. Prior knowledge of Java or functional programing would help. The language is exceptionally feature-rich which helps developers write less code and get faster results.
It is a combination of Spark, Mesos, Akka, Cassandra, and Kafka. You will learn how to integrate the technologies to build effective systems rather than getting incomplete information on single technologies. If you want to build a strong foundation with the Java Virtual Machine and get started with popular modern programming languages, then this book is for you. I'm a Java developer and I've been programming a bit of Scala in my spare time before reading this book. The last section, Scala Programming, contains a step-by-step guide to create a simple console-based application powered by the popular Akka tool kit. By writing example projects in those languages and focusing on each language's strong points, it will help you find the programming language that is most appropriate for your particular needs. Moving forward, you'll learn how to perform linear scalability in databases with Apache Cassandra.
Style and approach The design patterns in the book will be explained using real-world, step-by-step examples. Perhaps these things are really simple and don't require more than a short description, but for someone without the knowledge it would be very I'm a Java developer and I've been programming a bit of Scala in my spare time before reading this book. Section four, Java Programming, contains a step-by-step guide to creating a simple web service in the Java language. You will learn about the various features of Scala and be able to apply well-known, industry-proven design patterns in your work. This book will help you dive straight into app development by creating a real, reactive, and functional application. Style and approach This is a practical guide to data science that teaches theory by example through the libraries and frameworks accessible from the Clojure programming language.
Comes with lots of examples, you can spend a lot of time with them. I would recommend this for anyone interested in Scala who is already experienced with Java, C or C. It then walks you through different high-level concurrency abstractions, each tailored toward a specific class of programming tasks, while touching on the latest advancements of Async programming capabilities of Scala. Moving onto section five, Scala. You'll learn how to leverage the wealth of Java class libraries to meet the practical needs of enterprise and Internet projects more easily. Next you'll come to understand the Akka architecture. 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.
