ABSTRACT
#Microservices and #BigData 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.
#SpringFramework 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 #DataKay, 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 advocate Josh Long, and we'll explore the wacky, wonderful world of Reactive Spring together. [...]

We are currently releasing older YOW! videos to serve as a valuable archive, preserving historical content. It is possible that a video is perceived as outdated. We believe it offers insightful glimpses into the past, enriching our understanding of history and development.

If you are using Java for reactive (or any asynchronous) programming you are essentially using a hammer with a sharpened edge as a saw, and being told it is an amazing tool for cutting down trees - told by all the other people around you that have never used a real saw.

So you are talking about an axe to cut down a tree?

I think Project Loom will kill most of the interest in reactive programming in Java because it will no longer be absolutely needed for max performance.

Yeah, I have to wonder who would willingly go down that path if the jdk has magic built in.. Stack traces from hell, or just spin up a baby thread (virtual thread).

As far as I know, Project Loom doesn't provide an observable stream of values like an Observable or Flow. I think there will still be a need for libraries like RxJava for this use case.

@@robchr That's fair, I was thinking more of reactive Rest API code.

Update: Project Loom is great and all but the response times for Project Reactor are way better still because of its asynchronous nature.
