## Technologies used
Please check the [TechStack.md](TechStack.md) file for details.
## Description
This application is a demo application to show the power of Kotlin in a Reactive Programming environment.
We will also look at how to work with R2DBC and make comparisons between a typical Spring Boot Application and a Spring Boot WebFlux application with [JMeter](http://jmeter.apache.org/).
> In this example the domain revolves around the registration of concert dates, the artists and the show they belong to.
> We want to be able to record the concert data and make it the more efficient as possible.
> For this Demo we will use WebFlow
This project is also the official support project of my article on medium:
[](https://medium.com/swlh/comparing-webflux-and-spring-mvc-with-jmeter-79dc134c3c04)
Note that for the moment I'm keeping Kotest at version 4.4.0. This is to avoid an issue with MPP implementation.
Check the [Issues](./issues.md) document for more details
For further developments please have a look at branch [feature/research_and_development]()

## Structure
- [concert-demos-rest-service-webflux](./concert-demos-rest-service-webflux) - WebFlux implementation of the Sprig Boot Back-End process for the concerts website.
- [concert-demos-rest-service-mvc](./concert-demos-rest-service-mvc) - MVC blocking implementation of the Sprig Boot Back-End process for the concerts website.
- [concert-demos-data](./concert-demos-data) - Common data model

## JMeter
Part of this project is to perform benchmarking tests. For this, we will be using [JMeter](http://jmeter.apache.org/) by the [Apache Software Foundation](https://www.apache.org/).
