多位专家联袂推荐，360大数据专家撰写，基于Spark 2.1.0剖析架构与实现精髓。细化到方法级，提炼出多个流程图，立体呈现架构、环境、调度、存储、计算、部署、API七大核心设计。本书一共有10章内容，主要包括以下部分。 准备部分（第1～2章）：简单介绍了Spark的环境搭建和基本原理。本部分通过详尽的描述，有效降低了读者进入Spark世界的门槛，同时能对Spark背景知识及整体设计有宏观的认识。 基础部分（第3～5章）：介绍Spark的基础设施（包括配置、RPC、度量等）、SparkContext的初始化、Spark执行所需要的环境等内容。经过此部分的学习，将能够对RPC框架的设计、执行环境的功能有深入的理解，这也是对核心内容了解的前提。 核心部分（第6～9章）：为Spark最核心的部分，包括存储体系、调度系统、计算引擎、部署模式等。通过本部分的学习，读者将充分了解Spark的数据处理体系细节，能够对Spark核心功能进行扩展、性能优化以及对线上问题进行精准排查。 API部分（第10章）：这部分主要对Spark的新老API进行对比，对新API进行简单介绍。

This third edition brings the entire book, up to date, adding new material to cover features appearing in Scala versions 2.9 through Scala 2.12, including: String interpolation Functional Futures Implicit classes Defining new AnyVals Typeclasses and context bounds The latest style recommendations SAM support in Scala 2.12

Summary Akka in Action is a comprehensive tutorial on building message-oriented systems using Akka. The book takes a hands-on approach, where each new concept is followed by an example that shows you how it works, how to implement the code, and how to (unit) test it. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology Akka makes it relatively easy to build applications in the cloud or on devices with many cores that efficiently use the full capacity of the computing power available. It's a toolkit that provides an actor programming model, a runtime, and required support tools for building scalable applications. About the Book Akka in Action shows you how to build message-oriented systems with Akka. This comprehensive, hands-on tutorial introduces each concept with a working example. You'll start with the big picture of how Akka works, and then quickly build and deploy a fully functional REST service out of actors. You'll explore test-driven development and deploying and scaling fault-tolerant systems. After mastering the basics, you'll discover how to model immutable messages, implement domain models, and apply techniques like event sourcing and CQRS. You'l also find a tutorial on building streaming applications using akka-stream and akka-http. Finally, you'l get practical advice on how to customize and extend your Akka system. What's Inside Getting concurrency right Testing and performance tuning Clustered and cloud-based applications Covers Akka version 2.4 About the Reader This book assumes that you're comfortable with Java and Scala. No prior experience with Akka required.
