عرض عملي: عواصف إعادة المحاولة والعشوائية (Jitter)

خطوة بخطوة

1. Run 200 virtual users against inventory through Toxiproxy; make the service fail for 10 seconds.
2. Add fixed-interval retries (3 attempts, 100 ms) and watch request volume triple and recovery stall.
3. Planned mistake: also retry POST /payments automatically; show a customer charged twice in the test data. Fix: retry only idempotent calls or use an idempotency key.
4. Switch to exponential backoff with jitter and a limit; compare the request-rate graphs.
5. Add a retry budget or breaker so retries stop when the failure rate is high.
