A retry mechanism repeats a failed service-to-service request under defined conditions. Exponential backoff varies the delay between attempts, giving the failing service time to recover without being flooded. section 7.1.2
Use retries as one part of a broader service-interaction design:
- Pair retries with other cross-cutting concerns such as circuit breakers, rate limiting, and observability. section 7.1.2
- Consider how retry behavior affects troubleshooting when services use different frameworks or dependency versions. section 7.1.2
Service A calls Service B
When Service B temporarily fails, Service A retries the request with increasing delays rather than issuing requests at a fixed interval. The delay gives Service B time to recover and reduces retry pressure. section 7.1.2
