To implement at-least-once delivery in a RabbitMQ consumer using Go, you must use manual acknowledgements. This ensures messages are only acknowledged after successful processing, handling transient and permanent failures appropriately.

The best way to handle poison messages in RabbitMQ is by configuring a dead-letter-exchange with TTL-based retry mechanisms. This topology automatically routes failed messages away from the main queue to prevent blocking.

To ensure graceful shutdown for a Go RabbitMQ consumer, you must manage in-flight deliveries. This process ensures all active messages are processed and acknowledged before the consumer exits, preventing data loss during deployments.

Prefetch tuning affects competing consumers by limiting the number of unacknowledged messages a consumer can hold. Properly tuning this parameter ensures fairness and prevents a single slow consumer from hoarding messages in an event-driven architecture.

Yes, you can use the amqp091-go client to build crash-safe RabbitMQ consumers. It supports the manual ack contracts and broker-side topology management required for reliable message consumption in production-grade event-driven systems.
