What is spring boot starter WebFlux?

Spring WebFlux is parallel version of Spring MVC and supports fully non-blocking reactive streams. It support the back pressure concept and uses Netty as inbuilt server to run reactive applications. If you are familiar with Spring MVC programming style, you can easily work on webflux also.

What is spring reactive programming?

Reactive programming is a programming paradigm that promotes an asynchronous, non-blocking, event-driven approach to data processing. Reactive programming involves modeling data and events as observable data streams and implementing data processing routines to react to the changes in those streams.

Why is spring reactive?

Spring Webflux is a reactive-stack web framework that is fully non-blocking, supports Reactive Streams back pressure, and runs on such servers as Netty, Undertow, and Servlet 3.1+ containers. The reactor is a Reactive Streams library and, therefore, all of its operators support non-blocking back pressure.

What is R2DBC?

R2DBC stands for Reactive Relational Database Connectivity, a specification to integrate SQL databases using reactive drivers. It makes it easier to build Spring-powered applications that use relational data access technologies in a reactive application stack.

How to develop a reactive CRUD REST API with spring?

Also at DB side, we can use Spring Boot Reactive Database such as Mongo DB. As of now it has direct support of only NoSQL DB such as MongoDB and many more. Moreover, Spring Reactive is recommended instead of Spring REST. We will develop a Spring Webflux CRUD example to understand most of the concepts of Webflux.

How to use reactive APIs in spring webflux?

In this article, we will explore Spring WebFlux —reactive programming for RESTful web services in Spring Framework which is built on Reactive Streams APIs. The objective of this blog is to create a reactive RESTful app that can perform CRUD operations such as Create, Read, Update, and Delete using annotated controllers.

How is reactive programming used in webflux?

Reactive Programming ensures application resource utilization optimally instead of keeping threads in idle mode. It makes resource utilization accurately by implementing an event loop. When a thread makes database call, the call is handed over to event loop to process the Sql Query and thread becomes free for that duration.
