Report #104522

[architecture] What is the correct retry and backoff strategy for distributed systems?

Use exponential backoff with random jitter, cap maximum retries \(e.g., 3–5\), and pair with a circuit breaker to stop retries after sustained failures. Ensure operations are idempotent before retrying.

Journey Context:
Common mistakes include linear retries \(causing thundering herd if many clients retry simultaneously\) or no backoff at all. Exponential backoff reduces load on downstream systems, while jitter prevents synchronized retries. Circuit breakers avoid wasting resources when a service is down. The tradeoff is increased latency for legitimate transient failures, but the stability gain outweighs it. Alternatives like fixed intervals or multiple retries without backoff are inferior.
