How Retries Turn a Short Outage into a Long One
A retry loop looks harmless in a single client. Put the same loop in every client, gateway, service and driver, let one outage trigger all of them at once, and it turns into a load multiplier. This article goes through why that happens and what to do about it: amplification across layers, which failures to retry, timeouts and deadlines, backoff and jitter, retry budgets, library defaults with Resilience4j examples, Retry-After, idempotency keys, queue redelivery, and how to test all of it.
