Summary
In this chapter, you learned about Flowable
and backpressure and which situations it should be preferred over an Observable
. Flowables are especially preferable when concurrency enters your application and a lot of data can flow through it, as it regulates how much data comes from the source at a given time. Some Flowables, such as Flowable.interval()
or those derived from an Observable
, do not have backpressure implemented. In these situations, you can use onBackpressureXXX()
operators to queue or drop emissions for the downstream. If you are creating your own Flowable
source from scratch, prefer to use the existing Flowable
factories, and if that fails, prefer Flowable.generate()
instead of Flowable.create()
.
If you got to this point and understand most of the content in this book so far, congrats! You have all the core concepts of RxJava in your toolkit, and the rest of the book is all a walk in the park from here. The next chapter will cover how to create your own operators, which...
