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 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 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).

Don't you realize that the sea is the home of water? All water is off on a journey unless it's in the sea, and it's homesick, and bound to make its way home someday.

I think that one of the motivating factors was in my last year of law school: we had a competition, and I won the competition; it was judged by several of the federal judges at the time. I got a tremendous amount of encouragement to pursue litigation from them at the time.

Whatever the potential pitfalls, banks are increasingly enthusiastic about venture capital, particularly in new companies with strong prospects in fields like health care and technology.

I've found just the right amount of balance in my life. I'm this pop artist in America, but I'm also Malaysian. And I'm also Muslim.

People really, really hate their religion being criticized. It's as though you've said they had an ugly face; they seem to identify personally with it.

My problem with being an actor was that I was far too shy to actually do it.

As the egalitarianism of Marxism is attractive to many, socialism could have attracted many followers in America, anyway. But there is no doubt that it could not possibly have affected us so widely and so deeply as it has, had it not been heavily financed.

Folks do not want to see a body disappear before their very eyes. Not me at least.

I am choosing happiness.

US presidents can make all the commitments and declarations they want until they are blue in the face, in the Muslim world they will always be perceived as partisan.

Your feelings are important to write down, to capture, and to remember because today you're heartbroken, but tomorrow you'll be in love again.

Never make predictions, especially about the future.

I think it's important that people stand up for what they believe in.

Having a baby is part of a womans life and it is surely a great waste to be afraid of life.

The point of serving your country is not to do your own thing or to go rogue, but to work as part of the process.

I'm just a vessel of information.

In getting older, I find myself becoming progressively more ineffectual in a lot of different ways, and part of that is down to no longer having the youthful feeling that what you're doing has any true impact.

I do like to cook. But I only cook a few things, but those few things I do really well.

I never show the back of my tongue. That is a Dutch expression.

The Law of God in the Christian religion is the schoolmaster that leads us to Christ.

I rallied against Clinton when he was in office. I didn't vote for him in '96. I didn't vote for Gore in 2000.

Social Security is the very foundation of retirement security for millions of Americans.

They should just open lots of YouTube schools... as well as, like, a games school, where you can play all types of games. Like, if you want to play racing games, you go there and become a pro at that. Same for football or a shoot 'em up.

Courage, sacrifice, determination, commitment, toughness, heart, talent, guts. That's what little girls are made of.
