Heroku-如何保存状态

Question

I noticed that if there's no activity on the server for a while it shuts down and starts again when there's new activity, thus any previous states are gone.

For example, I have a list of connected users with the username they entered, and the list is emptied if there's no activity for a while.

What is the recommended way to save states on Heroku?

Would serializing the state to a file every few minutes work? Do I even have write access on Heroku?

您的HTTP服务器应该是无状态的-任何重要的信息都应该存储在其他地方，例如数据库。
