Learning Concurrent Programming in Scala Second Edition

Learn the art of building intricate modern scalable and concurrent applications using Scala About This Book * Make the most of Scala by understanding its philosophy and harnessing the power of multicores * Get acquainted with cutting-edge technologies in the field of concurrency through practical real-world applications * Get this step-by-step guide packed with pragmatic examples Who This Book Is For If you are a Scala programmer with no prior knowledge about concurrent programming or seeking to broaden your existing knowledge about concurrency this book is for you. Basic knowledge of the Scala programming language will be helpful. Also if you have a solid knowledge in another programming language such as Java you should find this book easily accessible. What You Will Learn * Get to grips with the fundamentals of concurrent programming on modern multiprocessor systems * Build high-performance concurrent systems from simple low-level concurrency primitives * Express asynchrony in concurrent computations with futures and promises * Seamlessly accelerate sequential programs by using data-parallel collections * Design safe scalable and easy-to-comprehend in-memory transactional data models * Transparently create distributed applications that scale across multiple machines * Integrate different concurrency frameworks together in large applications * Develop and implement scalable and easy-to-understand concurrent applications in Scala 2.12 In Detail Scala is a modern multiparadigm programming language designed to express common programming patterns in a concise elegant and type-safe way. Scala smoothly integrates the features of object-oriented and functional languages. In this second edition you will find updated coverage of the Scala 2.12 platform. The Scala 2.12 series targets Java 8 and requires it for execution. The book starts by introducing you to the foundations of concurrent programming on the JVM outlining the basics of the Java Memory Model and then shows some of the classic building blocks of concurrency such as the atomic variables thread pools and concurrent data structures along with the caveats of traditional concurrency. The book 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. It also covers some useful patterns and idioms to use with the techniques described. Finally the book presents an overview of when to use which concurrency library and demonstrates how they all work together and then presents new exciting approaches to building concurrent and distributed systems. Style and approach The book provides a step-by-step introduction to concurrent programming. It focuses on easy-to-understand examples that are pragmatic and applicable to real-world applications. Different topics are approached in a bottom-up fashion gradually going from the simplest foundations to the most advanced features. About the Author Aleksandar Prokopec who also authored the first edition of this book is a concurrent and distributed programming researcher. He holds a PhD in computer science from the Ecole Polytechnique Federale de Lausanne Switzerland. He has worked at Google and is currently a principal researcher at Oracle Labs. As a member of the Scala team at EPFL Aleksandar actively contributed to the Scala programming language and he has worked on programming abstractions for concurrency data-parallel programming support and concurrent data structures for Scala. He created the Scala Parallel Collections framework which is a library for high-level data-parallel programming in Scala and participated in working groups for Scala concurrency libraries such as Futures Promises and ScalaSTM. Aleksandar is the primary author of the reactor programming model for distributed computing.
