Event-Driven Failure Handling
Design for event failures
Handling failures in event-driven systems requires retry policies with backoff, dead-letter queues for poison messages, idempotent handlers, and event-level tracing/metrics to detect and replay safely.
- event failures
- dead letter
- retries
- idempotent
- observability
Retry Safely
Backoff with caps; classify retryable vs fatal errors.
Dead Letters
Route poison messages to DLQs with context and alerts.
Observe
Trace events; track lag/failures; support replay paths.

APIs let software request data or actions from other systems through defined endpoints and responses.
Comparison
RAM vs Storage
RAM handles what your device is actively working on, while storage keeps apps, files, and system data available over time.
How it works
Global Positioning System
GPS uses timing signals from satellites to calculate a receiver's position on Earth.
