Concert Demos

Technologies used

Please check the 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.

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:

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 document for more details

For further developments please have a look at branch feature/research_and_development
