We mainly use Mono, Flux and StepVerifier when working with Spring WebFlux and the project Reactor.

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.

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 had a writing professor at Brandeis who told me I'd never make it - and when I sold my first novel a few years later, I sent him a copy!

In such a case secrecy must be absolute to be effective, and although mere vague curiosity induced many persons of my intimate acquaintance to ask to be allowed to just go in and have a peep, I never admitted anyone.

And the best way to quit being concerned with yourself is to be concerned about others.

Its easy to be complicated but very difficult to be simple.

I've done well for myself.

Eat as much as you like - just don't swallow it.

Today you can't go by the titles of the shows to know what the content of the show may be.

I was born in 1991, and 'Harry Potter' came out in '97, so, you know, I was really obsessed. I used to read them in one night.

The two moments that I felt the most nervous in my entire life were when I first had reading rehearsal for 'G.I. Joe: The Rise of Cobra' and when I was at the Academy Awards ceremony.

We consider all our animals to be our kids.

The faith of religion is belief on insufficient evidence.

I don't have that X factor; I have to bank on my skills, be true to my character, and hope to be accepted.

You can never get silence anywhere nowadays, have you noticed?

For me, acting is play. It's just play and it's playing make believe really, really well.

I think that hate is a thing a feeling that can only exist where there is no understanding.

I was broke from 19 to 26, borrowing money from my parents or my brothers or sisters every week to pay the bills.

I just think too many nice things have happened in string theory for it to be all wrong. Humans do not understand it very well, but I just don't believe there is a big cosmic conspiracy that created this incredible thing that has nothing to do with the real world.

I like pineapple. It's delightful.

The Economist is undoubtedly the smartest weekly newsmagazine in the English language. I always look forward to its quirky year-end double issue.

The urge to write poetry is like having an itch. When the itch becomes annoying enough, you scratch it.

In a lot of ways, success is much harder than I thought it would be. I figured that you'd get here and then everything would be happily ever after. But, it's hard work, almost harder once you're successful because you've got to maintain it.

You have a choice. Choose positive, smiling, laughing. Life is too short for the alternative.

I don't want to give too much ink to foolish men.

My proudest moment was probably when my oldest boy finished law school and went on to become an FBI agent. It was just beyond my imagination that - with my background - my own son would become an FBI agent.
