If you are using Apache Tomcat to host a Java application connected to an AWS RDS database, there is a credential caching behavior worth understanding before you enable automatic rotation in Secrets Manager.
This is something I ran into while working on a cloud infrastructure project — and it is the kind of issue that looks fine until it suddenly is not.
**The Setup**
I was using Ansible to configure Apache Tomcat on an EC2 instance to host a Java application connecte
