Hi Rizzo, Did you check the aws-advanced-jdbc-wrapper, https://github.com/aws/aws-advanced-jdbc-wrapper? It provides a bunch of examples, including things like "Using the AWS IAM Authentication Plugin with DataSource", as well as support for HikariCP, c3p0, Spring. Unfortunately, I could find Quarkus was mentioned explicitly. I'd recommend giving it a try first. If the Quarkus datasource really limits the integration. We could think of using other data source libs, like HikariCP, DBCP, etc.
