ABSTRACT
Microservices and big data increasingly confront us with the limitations of traditional input/output. In traditional IO, work that is IO-bound dominates threads. This wouldn't be such a big deal if we could add more threads cheaply, but threads are expensive on the JVM, and most other platforms. Even if threads were cheap and infinitely scalable, we'd still be confronted with the faulty nature of networks. Things break, and they often do so in subtle, but non-exceptional ways. Traditional approaches to integration bury the faulty nature of networks behind overly simplifying abstractions. We need something better.
Spring Framework 5 is here! It introduces the Spring developer to a growing world of support for reactive programming across the Spring portfolio, starting with a new Netty-based web runtime, component model and module called Spring WebFlux, and then continuing to Spring Data Kay, Spring Security 5.0, Spring Boot 2.0 and Spring Cloud Finchley.
Sure, it sounds like a lot, but don't worry! Join me, your guide, Spring developer [...]

I love production. YOU should love production. You should go as early and often as possible. Bring the kids, bring the family. The weather is amazing. It's the happiest place on Earth. It's better than Disneyland. Hahaha Mr Long, well done.
I am a simple man, I see a talk by Josh -> Instant Like
In Hindi Language...Josh means abundant enthusiasm...and this man is no less than that... love his sessions.....
I don't how people commented clear, simple, etc. First 15 mins is just talk and after he takes bullet train of development and I can't match his pace. It must be great talk for those who are great learners and experience java/spring developers, but not for slow and new ones
Agreed
That was one of the best speeches I've seen about Reactive Spring + Josh is a funny guy, hahaha
Great talk... very useful for getting into reactive prog
clear and straight to the point! like it
Clearly explained why one should prefer reactive architecture to MVC model in the context of scaling. And also key role of protocols (http, Websockets and Rsockets) in applications architecture
Makes so much sense when you have worked with RxJS observables.
man, I need you in all in my projects
Great stuff!
Curious, is there a reason for spacing the params when typing code. 🤔. May be it feels good when its prettified?
34:45 without reactive spring, server sent events blocks a thread ?
Will the deep dive that he talked about be published? That would be awesome to see as well
The deep dive Josh mentions is a masterclass that lasted a full day. It has not been video recorded.
Even windows!
damn this guy speaks at 2x speed in real life
good presentation:) thanks
I learnt not only reactive probramming but a new way injecting dependency using Lombok and also a replacement of @PostConstruct. Bravo!
I like josh long, but you can start watch from 15min.
"I don't have much time."
Proceeds to babble and repeat himself for 15 minutes.
The rest of the talk is awesome, though.
I found the intro and motivation for reactive programming useful, starting from 3:13 and up to 14:30. Then skip to 15:30 because his jokes are bad.
I loved the jokes.
The build up before writing code was important though.
best speech
Why do we need backpressure for Mono?
Very entertaining. Good guy, knows his stuff. Only one thing pissed me off .. he used "efficient" and "polling" in the same sentence.
This guy is good
Cool idea, but how do we test it?
You can mock and stub it with various testing libraries, and if you have a callback that's multi-lined, then turn it into its own method, replace it with a method reference, and then you can unit test that method
Does anyone know why he uses Publisher instead of Flux as returned type of the request handler method on line 73 at 34:28?
Flux is a subtype of Publisher, so it’s the same.
It could be a Mono too
There is only on type of data published that is Publisher but these guys have decorated Publisher with Mono and Flux which is nothing but some additional behaviour to Publisher.
Here is Production and There is PHP. They should never come close. Haha.. Like your satire.
how fast can you talk: "yes"
can we find the repo of this talk somewhere?
I think this is github.com/joshlong/reactive-spring-article
hahahahahha Hide banner spring, "Disabled by order of Josh Long"
He is so fast at programming, it's quite baffling
hi there can you please share the code for this project please, and can i deploy a reactive project into a Wildfly and manage the Database conextion to tthe conextion with wilfy
I think this is github.com/joshlong/reactive-spring-article
Is he on of those PHP hater ?
Do I hear a Louis Rossmann in that talk?
nerdler boyle tipleri sever.
nodejs is better
Hi, why ?
@@diegov9799 because the support from v8 engine from google, the calaback queue, the Nature from JS wich is asynchronous
ofc it's better for small scale applications
its not typed language. I see a function which takes options object, how am I supposed to know what fields this so called object contains? not to mention, this can change at runtime too. And dont get me started with typescript. Its a poor mans type system that tries to fix the flaws of javascript.
It depends on the context...
