Production Defaults Example

This example demonstrates the production-ready defaults and queue configuration options in the go-rabbitmq library.

What This Example Shows

• Quorum Queues by Default: All queues are created as quorum queues for high availability
• Manual Dead Letter Configuration: Full control over dead letter exchange and routing setup
• Easy Customization: Simple options to customize quorum settings
• Legacy Compatibility: How to opt into classic queue behavior when needed

Running the Example

1. Ensure RabbitMQ is running locally:

   docker run -d --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management
   

2. Run the example:

   go run main.go
   

What Gets Created

The example creates several queues to demonstrate different configurations:

1. production-queue - Default quorum queue

   • Queue type: Quorum
   • High availability with replication

2. custom-quorum - Customized quorum queue

   • Quorum size: 5 nodes
   • Delivery limit: 3 attempts

3. dlq-example - Queue with manual dead letter configuration

   • Queue type: Quorum
   • Dead letter exchange: errors.dlx
   • Dead letter routing key: failed

4. legacy-classic - Classic queue for compatibility

   • Queue type: Classic
   • Message TTL: 1 hour

5. explicit-quorum - Using DeclareQuorumQueue method

   • Equivalent to default behavior now
   • Custom delivery limit: 5

Key Benefits

• High Availability: Quorum queues provide replication and fault tolerance
• User Control: Complete control over topology and dead letter configuration
• Flexibility: Mix and match different queue types and configurations as needed

Inspecting Results

You can view the created queues in the RabbitMQ Management UI at http://localhost:15672 (guest/guest).

Notice how:

• Queues show as "quorum" type with replication
• DLX and DLQ are automatically created and bound
• Arguments show the quorum and DLQ configurations
