minimumFetchInterval in Firebase remote config

Question

I'm using remote config to prompt user for a new update. What should I keep the minimumFetchInterval?

The dilemma is that if I keep this number too low (let's say 5 or 10 seconds), then it would increase the calls to firebase and if I keep it something as 60 minutes, then the update would be delivered late to the user.

Some advice or suggestions would be helpful.

From the Firebase documentation on throttling in Remote Config :

The default and recommended production fetch interval for Remote Config is 12 hours

So you should set it to 12 hours in production.

From the same page:

During app development , you might want to refresh the cache very frequently (many times per hour) to let you rapidly iterate as you develop and test your app. To accommodate rapid iteration on a project with numerous developers, you can temporarily add a property with a low minimum fetch interval ( Settings.minimumFetchIntervalMillis ) in your app.

So you can set it much shorter during development, because:

Keep in mind that this setting should be used for development only, not for an app running in production. If you're just testing your app with a small 10-person development team, you are unlikely to hit the hourly service-side quota limits . But if you pushed your app out to thousands of test users with a very low minimum fetch interval, your app would probably hit this quota.
