Graceful Degradation in Rust Services Under Heavy Load
A service that stays up by doing less beats one that tries to do everything and falls over. Decide in advance what to drop and how to say no quickly.

A service that stays up by doing less beats one that tries to do everything and falls over. Decide in advance what to drop and how to say no quickly.

Retries fix transient failures and amplify real outages. The right combination is a timeout per attempt, capped jittered backoff, a total deadline and a breaker that stops hammering.

Stop one failing dependency from taking the whole service down. A circuit breaker fails fast after repeated errors and probes for recovery; a bulkhead caps concurrency per dependency. Implement both with Tokio.
