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).

Without effective human intervention, epidemics and pandemics typically end only when the virus or bacteria has infected every available host and all have either died or become immune to the disease.

Avoid negative people, for they are the greatest destroyers of self confidence and self-esteem. Surround yourself with people who bring out the best in you!

Traditional PCs face competition from specialty products like Palm Pilots and from the servers that provide the nodes in computer networks. Microsoft's Windows CE hasn't done too well in the specialty-device market, and its Windows NT faces strong competition for server customers.

I inherited them, so I got it like that. But I hear you can actually get dimples for a certain price if you really want them. I was getting my nails done once, and this lady asked me, 'Are those real? In my country, they pay a lot of money for those.' And I was like, 'Really?' I think she was from Malaysia.

To tell you the truth, I thought I would be returning kicks and punts my whole career. I thought that was going to be my deal, and I was fine with that.

After being away from it for so long, it's really nice to go out and have 10- or 15,000 people show up and enjoy it. It leaves you with a very good feeling.

Almost every college playwright or sketch or improv comedian was sort of aware of Christopher Durang - even kids in high school. His short plays were so accessible to younger people and I think that was inspirational to me.

The real fight is within the Republican Party to get it to nominate grassroots-type candidates who the public wants, and not just some 'echo' of the other side.

It's good to be finally able to afford food for a change. It's good to move on from potatoes and tin soup.

There is something about inside information which seems to paralyse a man's reasoning powers.

You are such a blessing in my life. The kids are so happy and you keep all of us so happy. You are the man that any woman would want in her life. Thank you so much for being what you are.

The great thing about women directors is that they're not only involved in the performances - they can gauge where we all are personally and know how to direct us better because of that.

You can't generalise about an entire country, but I like the energy of British men.

The truth of a theory is in your mind, not in your eyes.

Eating is not a crime. It's not a moral issue. It's normal. It's enjoyable. It just is.

Numbers are limits, and perfection doesn't have limits.

I am joy.

Sometimes we waste too much time to think about someone who doesn't even think about us for a second.

A field of glory is a field for all.

You can't come away with this cosmic perspective thinking that you are better than others and want to fight. That's why you'll never have astrophysicists leading nations into war.

It is only by labor that thought can be made healthy, and only by thought that labor can be happy; and the two cannot be separated with impunity.

Love can neither be bought or sold, its only price is love.

It's hard to play basketball when nothing is inside of you.

Read a lot. Write a lot. Have fun.
