Kafka Retry Pipeline

An event-processing pipeline pattern for retries, backoff, poison messages, and dead-letter handling in Kafka-based systems.

Key components

• Primary Kafka topic receiving business events
• Consumer workers executing downstream side effects
• Retry topics for staged backoff windows
• Dead-letter topic for poison messages
• Idempotency store keyed by event or business identifier
• Monitoring pipeline for lag, retries, and failure rates

What usually breaks first

• Non-idempotent consumers can duplicate side effects during replay.
• Retry storms can amplify an already degraded downstream dependency.
• Poor partitioning can hotspot a single consumer and slow the full pipeline.
• DLQ growth without operator workflows turns silent failures into permanent data loss.
