Automated DLQ Remediation

Concepts: paDeadLetterQueue

What They Want to Hear 'I build automated remediation in tiers. Tier 1: automatic retry. Transient errors are retried with exponential backoff. Most DLQ events resolve themselves. Tier 2: automatic transform. Known schema mismatches are fixed by a remediation function: the event is transformed to the expected schema and replayed. Tier 3: human review. Events that fail automated remediation are grouped by error type, and the highest-impact group is surfaced to the on-call engineer. The system tracks resolution patterns and learns: if the same fix is applied manually 3 times, it becomes a Tier 2 automated transform.' This is the answer that shows you think about DLQ remediation as a system that improves over time.
