Reactive Streams specification contains 4 interfaces: Publisher, Subscriber, Subscription and Processor.

Spring uses the project Reactor as the implementation of the Reactive Streams Specification.

Asynchronous programming does not make the code faster than the synchronous version, but resource utilization is optimized and it's easier to scale.

We mainly use Mono, Flux and StepVerifier when working with Spring WebFlux and the project Reactor.

Mono produces 0..1 item.

Flux produces 0..N items.

StepVerifier is used to test Mono and Flux, mainly.

Both Mono and Flux implements Publisher.

RxJava2|Reactor => Observable|Flux, Single|Mono.

We can create Flux and Mono from methods like .just(), fromIterable() and many other from*() methods.

Spring Framework 5 requires Java 8.

Spring WebFlux uses Netty server by default.

Up to this day, there is not reactive implementations for JDBC drivers.

Spring WebFlux provides an annotation-based programming model where @Controller and @RestController components use annotations to express request mappings, request input, exception handling, and more.

Spring WebFlux includes a lightweight, functional programming model in which functions are used to route and handle requests and contracts are designed for immutability. It is an alternative to the annotated-based programming model but otherwise running on the same Reactive Spring Web foundation.

The spring-webflux module includes a reactive, non-blocking client for HTTP requests with a functional-style API client and Reactive Streams support called WebClient (AsyncRestTemplate has been deprecated).

My music is part of the quest I have to find new ways of telling stories, and also, I want to inspire people.

There's nothing easy about writing. It's always difficult. It's always a struggle.

My son died for lies.

I started out as a physicist; however, I am what I have become. I have evolved, with the help of many colleagues in the international scientific community, into an interdisciplinary scientist.

I just hope that some of the movies I'm in are still welcome years from now.

If nothing else came out of all of this debacle over Obamacare, one thing that should is a class-action lawsuit against the University of Chicago Law School for people that had Obama as their constitutional law professor.

Lacrosse is probably the best sport I ever played.

The kimono, haori, and girdle, and even the long hanging sleeves, have only parallel seams, and these are only tacked or basted, as the garments, when washed, are taken to pieces, and each piece, after being very slightly stiffened, is stretched upon a board to dry.

I've never liked watching real-life couples play couples onscreen or onstage. It takes me out of the story.

Female users are the unsung heroines behind the most engaging, fastest growing, and most valuable consumer Internet and e-commerce companies.

The tricks of magic follow the archetypes of narrative fiction - there are tales of creation and loss, death and resurrection, and obstacles that must be overcome.

I grew up watching Letterman, 'Seinfeld,' 'SNL,' and Monty Python movies. But nothing made me want to get into comedy more than when 'Mr. Show' started airing.

One of the great things about music is that it has the capability of time travel - you smell a certain smell in the room and it takes you back to your childhood. I feel like music is able to do that, and it happens to me all the time.

I would never call Jerusalem beautiful or comfortable or consoling. But there's something about it that you can't turn away from.

I am so thankful for the genius of Phil Spector, for his recognition of my talent to be the main voice of his Wall of Sound.

Social movements are at once the symptoms and the instruments of progress. Ignore them and statesmanship is irrelevant; fail to use them and it is weak.

Every gathering of Americans whether a few on the porch of a crossroads store or massed thousands in a great stadium is the possessor of a potentially immeasurable influence on the future.

I make clothing, and I don't care about trendy things.

Create each day anew.

There are so many people in the world and not everybody knows who I am, some people do, but I just don't think a lot of people know who I am.

Pollution from oil and gas development, toxic runoff, and miles and miles of plastic trash foul the waters and threaten marine life.

The American Indian was an individualist in religion as in war. He had neither a national army nor an organized church.

If a student takes the whole series of my folklore courses including the graduate seminars, he or she should learn something about fieldwork, something about bibliography, something about how to carry out library research, and something about how to publish that research.

Whatever you set aside to seek happiness remember where you put it.
