StepVerifier is used to test Mono and Flux, mainly.

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.

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).

We need to prepare our kids for a 21st Century economy, and we're not doing it with our schools.

My mom, Emilie, always taught me to think hard about marriage.

Anyone working in the media can tell you that there seems to be an always-ready-to-explode segment of the populace for whom offense is a fate worse than anything imaginable. You'd think offense is one of the most calamitous things that could happen to a human being; right up there with the loss of a limb, or just missing a parking space.

On Sundays, I'm up at five and in the office by six. After the show, around midday, I flip the switch, and it's all family. Our kids play sports, so we're running around.

When we talk about stem cells, we are actually talking about a complicated series of things, including adult stem cells which are largely cells devoted to replacing individual tissues like blood elements or liver or even the brain.

I was inspired to become a writer by horror movies and science fiction.

The most important principle for self discovery and to taste success is rather than changing other's attitude changes your own. And always remember same sun which melts the butter also hardens the clay.

There is something to be said for people who have to work hard, be creative, produce what they have with little - or no - means. Those of us from poor homes have the advantage of thinking for ourselves and of knowing that when times get hard, things could always be worse.

With each replacement of parts a car slowly becomes Chinese.

The kingdom of heaven is like electricity. You don't see it. It is within you.

There are thin girls with infertility issues, normal sized girls with infertility issues and overweight girls with infertility issues. Unless your doctor tells you your weight is affecting you in some way...once the doctor rules it out, that's really not it.

if fear is too strong, the genius is suppressed.

Radical transparency fosters goodness in so many ways for the same reasons that bad things are more likely to take place behind closed doors.

There's one thing that I like about Rome that was stated by Napoleon: that from sublime to pathetic is only one step away. And in Rome there's a constant shifting between sublime and pathetic.

I think what I was after was a unifying story that could bring everything together, that could give me a sense of the whole of history.

We must not in trying to think about how we can make a big difference ignore the small daily differences we can make which over time add up to big differences that we often cannot foresee.

Life is not accountable to us. We are accountable to life.

I think a lot of writing, or a lot of young writers, especially, hold themselves back unnecessarily because they're so upset about the idea that they might be sentimental or so concerned about being criticized that way or even being that way that they just shy away from any strong expression or emotion.

In managers, I look for people who can get things done through other people. The most important thing for a good manager is that the people on his team feel like he or she has integrity.

The technology at the leading edge changes so rapidly that you have to keep current after you get out of school. I think probably the most important thing is having good fundamentals.

The surfing - the waves in Indonesia are amazing.

People are capable of profound metamorphosis, though unfortunately they rarely avail themselves of this genius, force of habit being an even greater enemy of change than cowardice.

I didn't want to be a storyteller when I grew up; I wanted to be stuntman.

Biology list history is not built with ifs.
