Idiomatic Scala: Your Options Do Not Match:

This is a short reminder about Observable types in RxJava.
Observable is the simplest Observable which can emit more than one value.
Flowable is a Observable which can emit huge numbers of values which can’t be consumed by the Observer.
Single is a Observable which can emit only one value like a response from a network call.
Maybe is a Observable which can emit a value or no value.
Completable is a Observable which has to do some task without emitting a value
| Observable type | Number of values | Handlers |
| Observable | 1 or more | onNext, onError or onComplete |
| Flowable | Many with backpressure support | onNext, onError or onComplete |
| Single | 1 | onSuccess or onError |
| Maybe | 1 or nothing | onSuccess, or onComplete, or onError |
| Completable | No values | onError or onComplete |

Each time, when I return to development with Vertx, I have to decide what package to use: io.vertx.rxjava or io.vertx.reactivex? This is a reason, why I created this post.
io.vertx.rxjava package uses RxJava 1. io.vertx.reactivex package uses current RX extension – RxJava 2.
