RabbitMQ Tutorial

1. RabbitMQ Introduction

Run RabbitMQ with Docker and use the management UI to inspect exchanges, queues, and message rates.

2. Exchanges, Queues & Bindings

Direct, fanout, and topic exchanges with concrete routing-key examples, plus durable vs transient queues.

3. Publishing & Consuming Messages

A complete Node.js amqplib example publishing and consuming messages, with ack/nack semantics and prefetch.

4. Reliability Patterns

Publisher confirms, dead-letter exchanges for failed messages, and delayed retry strategies.

5. Clustering & High Availability

Classic mirrored queues vs quorum queues, and what actually happens to messages when a node fails.

6. Performance Tuning

Prefetch tuning, message size considerations, and connection/channel pooling.

7. Production Monitoring

Key metrics like queue depth and consumer utilization, and querying the management API.

8. RabbitMQ Interview Questions

Practical RabbitMQ interview questions on exchange types, ack/nack semantics, dead-letter exchanges, and durability.
