I want to store an environment variable that can be read elsewhere in my app. So plan to use Application.put_env. But I read that it is an opt that is a timeout. Does that mean after 5 seconds (default timeout) the environment variable goes away? I want it to last the lifetime of my app.

No, it means that putting env value is not instant and is not guaranteed.
Application.put_env/4usesapplication:set_env/4under the hood, so you can refer to its docs directly application — OTP 29.0.2 (kernel 11.0.2)I assume your application controller is not heavily loaded, so just don’t bother with this option
