How often should we open and close a db? On each request? Or each time a server comes up and goes down?

Sorry if this is the wrong place to post.

I’m wondering how often we should call

db, err := badger.Open(badger.DefaultOptions("/path/to/db"))
and
db.Close()

Is it something we should do once when the application starts up and then close when it goes down, or should we open and close with each request (in a web server context) or before and after each transaction?
