.hide() your Subjects - RxJava tip

A not so well known api in RxJava is the .hide() operator.

When does one use the hide operator in Rx? #

From the docs:

Hides the identity of this Observable and its Disposable.
Allows hiding extra features such as Subject’s Observer methods or preventing certain identity-based optimizations (fusion). there are a lot of complex operations that take place internally in RxJava (like internal queue creation, worker instantiation + release, numerous atomic variables being created and modified.)

RxJava 1 -> RxJava 2 (Understanding the changes)

In case you haven’t heard: RxJava2 was released sometime back. RxJava 2 was a massive rewrite with breaking apis (but for good reasons). Most dependent libraries have upgraded by now though, so you’re safe to pull that migration trigger with your codebases.

Folks starting out directly with Rx2 might enjoy this guide but it’s the ones that started with Rx 1 that will probably appreciate it the most.
