dead-letter-handling

Poison messages are routed to a dedicated dead-letter queue to preserve data. This approach captures unrecoverable processing errors safely, preventing data loss while enabling root-cause analysis and systemic fixes.

Retry with backoff is implemented as part of an end-to-end workflow for failed webhook deliveries. It applies progressive retry delays before permanently routing unrecoverable events to a durable DLQ table for investigation.

You can inspect, requeue, or discard failed jobs using provided admin tooling. These safe admin endpoints allow operators to manage DLQ items directly and set thresholds for automated routing.

You need a dead-letter queue when handling permanent failures in event processing. It prevents data loss by capturing unrecoverable errors, allowing you to safely investigate and apply systemic fixes.

Dead-letter handling applies across events, jobs, and webhook deliveries in SaaS systems. It provides a unified, production-grade pattern to safely manage routing and investigation for all these processes.
