In this episode of Fragmented, Donn and Kaushik continue their conversation with Dan Lew on RxJava. In the final part of this 2 part series, they talk about many useful RxJava operators and other intricacies of using RxJava in Android.

RxJava Operators:

Observable.just [reactivex.io]
Observable.from [reactivex.io]
Observable.defer [reactivex.io]
- Using defer to handle “Old, Slow Code” [blog.danlew.net]
Observable.map [reactivex.io]
Observable.flatmap [reactivex.io]
- map vs flatmap (alchemist and cheese shredding analogy [reddit])
Observable.zip [reactivex.io]
Observable.combineLatest [reactivex.io]
Observable. switchMap [reactivex.io]
Observable.distinctUntilChanged [reactivex.io]
Observable.lift explanation [reactivex.io]
Observable.compose
- Don’t break the chain (using compose) [blog.danlew.net]
Observable.filter [reactivex.io]
Observable.take [reactivex.io]
subscribeOn vs observeOn [stackoverflow.com]

Hot vs Cold observables - From the RxJs wiki [github.com]

uses js instead of java, but concepts are the same and this is the best explanation I’ve found so far.

RxJava wiki on Backpressure [github.com]:

Ring buffer size: System.setProperty("rx.ring-buffer.size", "128");
Issue with changing buffer ring size [github.com]
It’s 16 on Android, down from 1024 originally. :P So it’s actually 64x smaller.
