Backpressure in Distributed Systems: Practical Flow Control
Design backpressure with demand signals, bounded buffers, admission control, timeouts, load shedding, and queue metrics so slow consumers stay contained.
Handling 429 Too Many Requests from Rate-Limited APIs
Handle HTTP 429 responses safely with Retry-After, bounded exponential backoff, jitter, shared client budgets, idempotency, and rate-limit monitoring.
Dead Letter Queues: Monitoring, Triage, and Safe Redrive
Learn why messages enter a dead letter queue, what metadata to retain, how to alert and triage failures, and how to redrive safely without duplicates.
Circuit Breaker Pattern: States, Tuning, and Monitoring
Implement circuit breakers with closed, open, and half-open states; tune failure windows, probe recovery, fallbacks, and alerts without masking outages.
Exponential Backoff & Jitter: Stop Retry Storms (Code & Math)
Learn how exponential backoff with jitter prevents retry storms. Compare full, equal, and decorrelated jitter formulas, retry budgets, and code examples.
Graceful Degradation: Designing Systems That Fail Well
Design graceful degradation with fallbacks, deadlines, circuit breakers, load shedding, kill switches, and explicit monitoring for degraded states.
