Reactive Streams are a standard approach to handling concurrency in modern applications. The Java 9 release includes new support for reactive streams. This book attempts to provide an easy introduction to Reactive Streams in Java including in depth introductions to RxJava, Akka Streams, and Reactor and how they can be used.
This book will cover everything you need to know about existing projects and how they translate in Java 9.
This book uses a progressive publishing model. As the book grows, so does the price. This encourages early adopters.
This book has been picked up by a publisher and will be published in finished version later this year (winter 2018).
