Reactive manifesto
•
2013. team of developers, lead by Jonas
Boner came
together to define a set of core principles.
•
The manifesto defines the fundamental
characteristics or principles of a reactive system.
•
It prescribes the recipe for a reactive system to be
flexible, loosely-coupled, and scalable.
Naslov
Elastic and Message driven
•
Elasticity builds upon scalability and expands on it by adding the notion of
automatic resource management.
•
Message driven vs. Event driven
•
Resilience is more difficult to achieve in an event-driven system.

If you have a Spring MVC application that works fine, there is no need
to change.

Large team
•
JPA, JDBC
•
Have a Spring MVC application with calls to remote services
•
Microservice architecture
•
Netty, Tomcat, Jetty,.. Reactor, RxJava,..

•
Mono
– A Mono object represents a single value or empty value
(0 to 1) item, e.g. Mono<T>
•
Flux
– It represents a reactive sequence of 0 to N items. For
example, Flux<T>
