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).

Give every man your ear, but few thy voice. Take each man's censure, but reserve thy judgment.

The more you consume, the more insecure you are. It's the nature of the world.

I think the next president ought to invoke the Fifth and Fourteenth Amendments to the Constitution now that we clearly know that that baby inside the mother's womb is a person at the moment of conception.

My music is evidence of my soul's will to live.

I'm not like a legend that - so I'm sort of in the middle in this sort of gray area where, you know, I'm creating music, and I'm not saying there isn't an audience, because there is; because all of those people go out and spend $80 to $150 on a concert ticket.

Free speech is not to be regulated like diseased cattle and impure butter. The audience...that hissed yesterday may applaud today even for the same performance.

When under siege, if we do not stand for our liberties and for the liberties of those who are unable to stand for themselves, then the great American experience will come to an end.

Agatha Christie has given more pleasure in bed than any other woman.

One of the key places where sociology should be used is in analyzing 'the world' of our times, so that we can be more discerning. To resist the dangers of the world, you have to recognize the distortions and seductions of the world.

All the miseries and evils which men suffer from vice, crime, ambition, injustice, oppression, slavery and war, proceed from their despising or neglecting the precepts contained in the Bible.

I know the word 'sacrifice.'

The Christ-symbol is of the greatest importance for psychology in so far as it is perhaps the most highly developed and differentiated symbol of the self, apart from the figure of the Buddha.

I'm a very spontaneous person, for the bad and the good.

I've read a number of relationship books out there. A lot are written towards women.

Antibiotics are so pervasive that they are often prescribed preemptively, as soon as patients report symptoms, before a diagnosis is made.

As long as I am an American citizen, and as long as American blood runs in these veins, I shall hold myself at liberty to speak, to write, and to publish whatever I please on any subject, being amenable to the laws of my country for the same.

One of the things that happens when people make the leap from a certain amount of money to tens of millions of dollars is that the people around you dramatically change.

Wherever I go, there's always a child, an old woman, that comes to me and wants to meet me. Not because I am famous but because they suffered with my family.

Well, you need the villain. If you don't have a villain, the good guy can stay home.

You can't be a Red if you're married to a civil servant.

If you compared your troubles or challenges with those of others you would surely find that there are those whose troubles make yours look like minor inconveniences.

I thought maybe I'd be a female sportscaster.

I'm a strong person, I'm a strong family man, I'm a strong husband and a strong father.

As an Egyptian, I was always frustrated, just like many young Egyptians, of the situation in the country. And to a large extent, we didn't know what could we do. And looking at Khaled's photo after his death; basically I just felt that we are all Khaled Said.
