Why This Topology Works
RabbitMQ with dead-letter queues ensures no message is lost during SAP sync failures. Retry policies with exponential backoff handle transient ERP outages gracefully.
Scaling Notes
Queue workers scale based on queue depth. Dead letter queue isolates poison messages for manual inspection without blocking the pipeline.
Observability
Queue depth and consumer lag metrics feed alerting. Failed messages in DLQ trigger PagerDuty notifications.
