Concurrency in Spring WebFlux

Concurrency in Spring WebFlux. Concurrency in Spring Webflux depends on many factors. Let's explore them in-depth.

1. Introduction

In this tutorial, we'll explore concurrency in reactive programs written with Spring WebFlux.

We'll begin by discussing concurrency in relation to reactive programming. After that, we'll explore how Spring WebFlux offers concurrency abstractions over different reactive server libraries.

2. The Motivation for Reactive Programming

A typical web application comprises of several complex, interacting parts. Many of these interactions are blocking in nature like, for example, those involving a database call to fetch or update data.  Several others, however, are independent and can be performed concurrently, possibly in parallel.

For instance, two user requests to a web server can be handled by different threads. On a multi-core _platform, this has an obvious benefit in terms of the overall response time. Hence, **this model of concurrency is known as the thread-per-request model_**:

In this tutorial, we'll explore the @Async annotation in Spring MVC, and then we'll get familiar with Spring WebFlux. Our goal is to have a better understanding of the difference between these two.

See how to Build Reactive REST APIs with Spring WebFlux. This explains the advantages we get with Reactive APIs and the reactive specification.
