Leverage Scala and the functional paradigm to build performant software About This Book * Get the first book to explore Scala performance techniques in depth! * Real-world inspired use cases illustrate and support the techniques studied and the language features * This book is written by Vincent Theron and Michael Diamant, software engineers with several years of experience in the high-frequency trading and programmatic advertising industries Who This Book Is For This book assumes a basic exposure to the Scala programming language and the Java Virtual Machine. You should be able to read and understand moderately advanced Scala code. No other knowledge is required. What You Will Learn * Analyze the performance of JVM applications by developing JMH benchmarks and profiling with Flight Recorder * Discover use cases and performance tradeoffs of Scala language features, and eager and lazy collections * Explore event sourcing to improve performance while working with stream processing pipelines * Dive into asynchronous programming to extract performance on multicore systems using Scala Future and Scalaz Task * Design distributed systems with conflict-free replicated data types (CRDTs) to take advantage of eventual consistency without synchronization * Understand the impact of queues on system performance and apply the Free monad to build systems robust to high levels of throughput In Detail Scala is a statically and strongly typed language that blends functional and object-oriented paradigms. It has experienced growing popularity as an appealing and pragmatic choice to write production-ready software in the functional paradigm. Scala and the functional programming paradigm enable you to solve problems with less code and lower maintenance costs than the alternatives. However, these gains can come at the cost of performance if you are not careful. Scala High Performance Programming arms you with the knowledge you need to create performant Scala applications. Starting with the basics of understanding how to define performance, we explore Scala's language features and functional programming techniques while keeping a close eye on performance throughout all the topics. We introduce you as the newest software engineer at a fictitious financial trading company, named MV Trading. As you learn new techniques and approaches to reduce latency and improve throughput, you'll apply them to MV Trading's business problems. By the end of the book, you will be well prepared to write production-ready, performant Scala software using the functional paradigm to solve real-world problems. Style and approach This step-by-step guide will help you create high performance applications using Scala. Packed with lots of code samples, tips and tricks, every topic is explained in a detailed, easy-to-understand manner.

A Must read for anyone writing Scala in a High Performance Environment!

Great book that takes you from the basic building blocks of performance testing all the way to implementing and testing a high performance trading system in Scala. It shows the tradeoffs from different design patterns and hidden gotchas in Scala and the JVM ecosystem. A must read for anyone who's writing Scala/Java code in a High Performance Environment!

As there were a few reviews I wanted to add my contribution. This book is indeed very good, it's going through an application and checks many aspects around its scala coding techniques and its scalability. It consistently analyzes the byte code and desugaring of the scala code to understand its performance penalty. All in all it was indeed a great book, personally I just like it when the examples are very very short and concise i prefer in books more text less code to understand the concept this is why from my view 4 stars.

A unique perspective on writing highly performant functional Scala code

2016年7月5日 - 已在美国亚马逊上发表

Disclaimer: I was the technical reviewer for this book.

Nowadays there are many books written on the topic of Scala and its ecosystem, so it is not an easy task to bring a unique perspective. This book succeeds in doing so, as it focuses on producing highly performant code while staying within the realm of functional programing. To some that may sound as an oxymoron, but the authors prove in this book it is quite possible to achieve the goal, using a problem from a real-world business domain.
I would highly recommend this book to anyone interested in hands-on learning of computing performance on the JVM platform. As a bonus, you will get exposed to a lot of intricacies of Scala not covered in other books.
