How to turn off DNS caching

I am trying to connect to my AWS RDS (mysql) instance using the AWS supplied
DNS endpoint.

The problem is, the IP of the instance changes periodically.

It appears that nginx does not resolve the DNS name every time, but caches

Therefore nginx initially works, then at some point later, things break.

How can I turn off the DNS caching?
