In this tutorial I will explain how to create a quarkus based java application that will use reactive datasource to connect to a postgres database and be able to perform crud operations via rest endpoint.

To lern more about benefits of reactive data sources vs. jdbc regular data sources you can go to following link https://cutt.ly/1l260tK. Step 1: Configure Project
