What are the features of RabbitMQ?

RabbitMQ is a message broker implementing the AMQP protocol. Its features:

• Reliability and delivery guarantees: supports message acknowledgments, persistence, and transactions.
• Flexible routing: using exchanges, different message delivery schemes can be configured (direct, topic, fanout, headers).
• Support for multiple clients and languages: libraries are available for Go, Python, Java, and others.
• Queue management: queues can be durable, temporary, with size limits.
• Monitoring and management: there is a web interface and API for administration.
• High performance: suitable for high-load systems.

Example of usage in Go with the amqp library:

conn, err := amqp.Dial("amqp://guest:guest@localhost:5672/")
// handle err
ch, err := conn.Channel()
// handle err
q, err := ch.QueueDeclare("task_queue", true, false, false, false, nil)
// handle err
body := "Hello RabbitMQ"
err = ch.Publish("", q.Name, false, false, amqp.Publishing{
    ContentType: "text/plain",
    Body:        []byte(body),
})
// handle err

RabbitMQ is well-suited for asynchronous task processing, distributed systems, and microservices.
