Discover how project Reactor enhances the reactive programming paradigm and allows you to build scalable asynchronous applications Key Features Use reactive APIs, Flux, and Mono to implement reactive extensions Create concurrent applications without the complexity of Java's concurrent API Understand techniques to implement event-driven and reactive applications Book Description Reactor is an implementation of the Java 9 Reactive Streams specification, an API for asynchronous data processing. This specification is based on a reactive programming paradigm, enabling developers to build enterprise-grade, robust applications with reduced complexity and in less time. Hands-On Reactive Programming with Reactor shows you how Reactor works, as well as how to use it to develop reactive applications in Java. The book begins with the fundamentals of Reactor and the role it plays in building effective applications. You will learn how to build fully non-blocking applications and will later be guided by the Publisher and Subscriber APIs. You will gain an understanding how to use two reactive composable APIs, Flux and Mono, which are used extensively to implement Reactive Extensions. All of these components are combined using various operations to build a complete solution. In addition to this, you will get to grips with the Flow API and understand backpressure in order to control overruns. You will also study the use of Spring WebFlux, an extension of the Reactor framework for building microservices. By the end of the book, you will have gained enough confidence to build reactive and scalable microservices. What you will learn Explore benefits of the Reactive paradigm and the Reactive Streams API Discover the impact of Flux and Mono implications in Reactor Expand and repeat data in stream processing Get to grips with various types of processors and choose the best one Understand how to map errors to make corrections easier Create robust tests using testing utilities offered by Reactor Find the best way to schedule the execution of code Who this book is for If you’re looking to develop event- and data-driven applications easily with Reactor, this book is for you.

"Reactive and asynchronous applications are growing in popularity, but what is the best way to build them? This course, designed for software architects and intermediate- to advanced-level Java programmers, teaches you how to apply the latest concurrency techniques to develop state of the art Java applications. With the rise of microservices and service oriented architectures (SOAs), asynchronous concurrency is now critical in day-to-day Java development. This course builds upon theory offered in the associated "Asynchronous Programming in Java" course by refactoring several Java projects using RxJava. It explains the concepts behind this popular library, shows how RxJava compares with other concurrency concepts, and illustrates how to use the library productively in practice."--Resource description page.

The emerging reactive model is ideal for high-performance web applications that need to manage the unpredictably-bursty behavior of the web, along with the potential instability of running on networks not fully controlled. By using application components that communicate asynchronously as they react to user and system events, reactive applications are more scalable, responsive, and fault-tolerant than standard monolithic applications. For web developers working in Java or Scala, the Play framework makes it easy to implement reactive applications without taking on the overhead of building everything from scratch. Reactive Web Applications teaches web developers how to benefit from the reactive application architecture and presents hands-on examples using the Play framework. It introduces Play as a framework to handle the plumbing of applications. The book alternates between chapters that introduce reactive ideas like asynchronous programming, managing distributed state, and fault tolerance and examples that show how to build such applications using Play. Readers new to Play will be able to learn from the ground up. Those already using Play will get a deeper look at how to implement reactive web applications effectively. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

"The Spring Framework is one of the most widely used open source projects in the Java world. It combines dependency injection and lifecycle management with a large library of useful classes to provide enterprise services like transactions, security, and persistence. The Spring Boot project added powerful auto-configuration capabilities to the framework, making it easy to create and customize applications, including RESTful microservices. The Spring 5 and Spring Boot 2 releases brought the Reactive Streams standard to the overall architecture. The reactive approach in Spring adds nonblocking, asynchronous capabilities to the framework, with backpressure, in a way consistent with the new Java 9 specification. This intermediate-level video course shows you how to write applications in the new reactive style by taking advantage of the capabilities now available in Spring and Spring Boot. Participants should be comfortable with lambdas, streams, and method references in Java 8; they should also have a basic understanding of the Spring framework in any version prior to 5."--Resource description page.

Understand the newest trend in database programming for developers working in Java, Kotlin, Clojure, and other JVM-based languages. This book introduces Reactive Relational Database Connectivity (R2DBC), a modern way of connecting to and querying relational databases from Java and other JVM languages. The book begins by helping you understand not only what reactive programming is, but why it is necessary. Then building on those fundamentals, the book takes you into the world of databases and the newly released Reactive Relational Database Connectivity (R2DBC) specification. Examples in the book are worked using the freely available MariaDB database along with MariaDB’s vendor-implementation of the R2DBC service-provider interface (SPI). Following along with the examples and the provided example code helps prepare you to work with any of the growing number of R2DBC implementations for popular enterprise databases such as Oracle Database and SQL Server. You’ll be well prepared for what is becoming the future of database access from Java and other languages built on the JVM. What You Will Learn Understand why R2DBC was created and how it utilizes the Reactive Streams API Understand the components of the R2DBC service-provider interface Create and manage reactive database connections and connection pools using an R2DBC client Programmatically execute queries on a relational database using an R2DBC client Effectively utilize transactions using an R2DBC client Build relational database-driven applications that are event-driven and non-blocking Who This Book Is For Software developers building solutions using JVM languages and the JVM ecosystem, and developers who need an introduction to the R2DBC specification and reactive programming with relational databases and want to understand what Reactive Relational Database Connectivity is and why it came about. This book includes practical examples of using the R2DBC specification with Java and MariaDB that will provide developers with the knowledge they need to create their own solutions.
