Reactive Spring Deep Dive: Building & Testing Reactive Cloud-native Java Microservices

This presentation accompanies a three hour session in which I discuss and demonstrate by live coding the following material/topics:

* Build reactive data mechanisms that store & retrieve data from four different NoSQL databases, comparing & contrasting them
* Build a fully reactive Java microservice that extends our reactive data access up through internal and external APIs
* Discuss the challenges associated with testing reactive applications and show how to do so properly
* Demonstrate how to debug reactive applications when things go off the rails
* Replace Spring MVC-style route definitions with *functional* reactive route definitions
* Build in (reactive) Spring Security to secure our critical services and data
* Create a reactive client, with security of course
* Build a reactive microservice using Kotlin

Please contact me at the coordinates in the intro slides for more information or to schedule me for your event!

3. @mkheck @springdata @projectreactor –Rossen Stoyanchev, Project Reactor team “In a nutshell reactive programming is about non-blocking, event-driven applications that scale with a small number of threads with backpressure as a key ingredient that aims to ensure producers do not overwhelm consumers.”
