I have a heroku app operated by free dynos. This app is called -- let us say -- 5 times a day by users at random times. It serves a request in 3-4 milliseconds. At every request a dyno is awakened and having served the request this dyno listens for 30 minutes needlessly. Is there any possibility to set the default 30 minute "go to sleep" time to e.g. 15 seconds or something like that?
I checked https://devcenter.heroku.com/articles/free-dyno-hours, it does not say anything on this.
