RxJava 2.0 - How to convert Observable to Publisher

Question

How to convert Observable to Publisher in RxJava version 2?

In the first version we have the https://github.com/ReactiveX/RxJavaReactiveStreams project that do exactly what I need. But How can I do it in RxJava 2?

Answer 1

Use the following code:

Publisher publisher = observable.toFlowable(BackpressureStrategy.XXX);

As Observable does not implement backpressure, you need to select backpressure strategy when converting. See available choices here .

Or use Flowable instead of Observable in the first place. See here for details.
