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

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

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

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).

I would never dispute that I've been given a gift by God. That's something I've been raised to believe. I'm not an idiot: I know that I can sing, and I know that I can act.

The one thing I think I've noticed about shows that are supposed to be funny on television is that they've sort of become routinized, so there's an awful lot of mannerisms and joke lines that are sort of there to trigger laughter, rather than give actors a chance to play a moment.

The most important kind of freedom is to be what you really are.

To err is human. To blame someone else is politics.

Japan is the largest creditor country in the world, so we have made contributions to the stability of international markets and we want this IMF meeting to confirm that we will continue to contribute.

Jazz is the last refuge of the untalented. Jazz musicians enjoy themselves more than anyone listening to them does.

As much as it hurts, I would rather miss someone than hit someone.

I find myself going out less and less. When you're 22 and see older people start to do that, it's depressing, but once you hit 30, you think, 'Wow, I've been working all week - it might be really nice to stay in!'

This man called President Bush has a lot to answer for. I don't know if this man is really taking care of America. This government has been shameful.

Agnostic for me would be trying to weasel out and sound a little nicer than I am about this.

Dressing up, for me, is looking like an idiot.

Republicans understand the importance of bondage between a mother and child.

When I multiply numbers together, I see two shapes. The image starts to change and evolve, and a third shape emerges. That's the answer. It's mental imagery. It's like maths without having to think.

If there is something I like, I buy it and then find somewhere for it. I buy first then I think.

I'm a creative person who had a lot of dark time in my life. I can still get to it: I can still go to a relationship or a time when things weren't great. But it's getting further and further from me.

It is true that if you hear our music described, it sounds unappealing. I used to laugh and agree with people when they said it didn't make any sense.

A bore is a man who when you ask him how he is tells you.

That's really one of the things I love about video games. It's a whole new world every time you start.

A man is entitled to a few secrets.

I myself owe everything to French books. They developed in my soul the sentiments of humanity which had been stifled by eight years of fanatical and servile education.

It's inevitable now, because everyone is a superstar, even if they're just an average player, and maybe that was part of the process set in motion when I signed that contract in 1994.

I don't like being out in public too much. I don't like going to bars. I don't like doing celebrity stuff.

I am basically the sort of person who has stage-fright teaching. I kind of creep into a classroom. I'm not an anecdote-teller, either, although I often wish I were.

What I learned from my years in Silicon Valley is that design can have a primary role in how a business is shaped, how a company can be design-driven. In my experience of large industry in Europe, that knowledge has been lost.
