What are RabbitMQ queues and how do they work?

What are RabbitMQ queues and how do they work?

RabbitMQ queues are data structures that store messages sent from producers until they are consumed by consumers. They enable asynchronous communication.

Can you explain how messages are routed to queues?

Messages are routed to queues based on routing keys and bindings defined in exchanges. The exchange determines how to distribute messages.

What types of exchanges are there in RabbitMQ?

There are four main types of exchanges: direct, topic, fanout, and headers. Each type routes messages differently based on specific criteria.

How can I monitor RabbitMQ queues?

You can monitor RabbitMQ queues using the RabbitMQ Management Plugin, which provides a web-based UI to view queue metrics and message rates.

Are there any best practices for managing queues?

Yes, some best practices include setting appropriate TTLs for messages, using dead-letter exchanges, and monitoring queue lengths to avoid bottlenecks.
