Overview of this book

RxJava is a library for composing asynchronous and event-based programs using Observable sequences for the JVM, allowing developers to build robust applications in less time. Learning RxJava addresses all the fundamentals of reactive programming to help readers write reactive code, as well as teach them an effective approach to designing and implementing reactive libraries and applications. Starting with a brief introduction to reactive programming concepts, there is an overview of Observables and Observers, the core components of RxJava, and how to combine different streams of data and events together. You will also learn simpler ways to achieve concurrency and remain highly performant, with no need for synchronization. Later on, we will leverage backpressure and other strategies to cope with rapidly-producing sources to prevent bottlenecks in your application. After covering custom operators, testing, and debugging, the book dives into hands-on examples using RxJava on Android as well as Kotlin.

Switching, Throttling, Windowing, and Buffering

It is not uncommon to run into situations where an Observable is producing emissions faster than an Observer can consume them. This happens particularly when you introduce concurrency, and the Observable chain has different operators running on different Schedulers. Whether it is one operator struggling to keep up with a preceding one, or the final Observer struggling to keep up with emissions from the upstream, bottlenecks can occur where emissions start to queue up behind slow operations.

Of course, the ideal way to handle bottlenecks is to leverage backpressure using Flowable instead of Observable.The Flowable is not much different than the Observable other than that it tells the source to slow down by having the Observer request emissions at its own pace, as we will learn about it in Chapter 8, Flowables and...
