Your weather app queries a database every 15 minutes to get the current temperature. The frontend is powered by Google App Engine and serves millions of users. How should you design the frontend to respond to a database failure?
-
The frontend should not restart database servers; that is an operations concern and does not handle the failure gracefully.
-
Exponential backoff with a cap is the standard resilient retry strategy.
-
Retrying every second from many instances creates a thundering herd that hinders recovery.
-
A fixed hourly interval increases staleness without adapting to recovery.
