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

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

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).

To be famous and broke is hard.

That's a part of me going back to what I used to do.

The building blocks of mathematical thinking are requisite for more advanced conceptualization. If a student is not ready to move on, then the teacher must take time to assist that learner.

If I get to be president, what can I do anyway? With Congress and the press, what chance do I have to make basic changes?

I grew up in Zimbabwe in Southern Africa, and I moved to London when I was 17. And I started commuting and, actually, to go to college. And I used to really enjoy that part of my journey where the - it was actually a Tube train, but it was over ground, and it went right past the backs of people's houses, and I could actually see right in.

It is true that some people are interested in the buying part of things... They want to buy everything from the movie reviews to the media net to the opinions and so on.

Singing really oxygenates your blood. You stretch your lungs and take in much more air into them than before. It's really good for your health.

I don't plan massively in advance.

I wouldn't mind being the lead guitarist in an incredibly successful rock band. However, I don't play the guitar.

If a voter initiative can deny gay people access to traditional representative, democratic processes, then in California, any other small, historically disadvantaged minority group can also be denied the right of representative.

Nothing can supply the place of books. They are cheering or soothing companions in solitude illness affliction. The wealth of both continents would not compensate for the good they impart.

In my mind, there are too many copycat web products out there that are doing the same thing.

You have more to do than be weighed down by pretty or beautiful. You are a fiery heart and a wicked brain. Do not let your soul be defined by its shell.

There wasn't much around. After the shows, we would go to an Italian restaurant that a friend of ours owned and so I didn't get a chance to see much. Actually, that holds true of most places I've been.

I hope, by God's grace, that I am truly a Christian, not deviating from the faith, and that I would rather suffer the penalty of a terrible death than wish to affirm anything outside of the faith or transgress the commandments of our Lord Jesus Christ.

I don't like scaring people off. When I tell people I'm a writer, they look kind of interested. Then I tell them that I write poetry, and they think I'm weird.

We may smile at these matters, but they are melancholy illustrations.

I don't work on a project unless I believe that it will dramatically improve life for a bunch of people.

From the mid-1970s, I also started work on the causation and prevention of famines.

A man's got to work for more than himself and his kids to feel right.

People are inclined to say that I am Ramona. I'm not sure that's true, but I did share some experiences with her.

I don't intend to retire.

Only in spontaneity can we be who we truly are.

World peace is no longer some pie-in-the-sky thing, because no single person or country is going to solve it on their own.
