What messaging tool was used in the previous project?

In the previous project, RabbitMQ was used as the message broker. It is a popular tool that allows applications to exchange data asynchronously through message queues.

RabbitMQ supports various protocols, ensures reliable message delivery, and scalability. It is well-suited for distributed systems where components need to interact independently and efficiently.

An example of its use in Python with the pika library:

import pika

connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()

channel.queue_declare(queue='task_queue', durable=True)

channel.basic_publish(
    exchange='',
    routing_key='task_queue',
    body='Hello World!',
    properties=pika.BasicProperties(
        delivery_mode=2,  # make the message persistent
    ))

print(" [x] Sent 'Hello World!'" )
connection.close()

If a different tool was used in your project (for example, Kafka, Redis Pub/Sub), please specify it.
