Have you used RabbitMQ yourself or only heard about it from the team?

Yes, I have used RabbitMQ in several projects. It is a message broker that allows organizing asynchronous data exchange between services.

Example of usage in Python with the pika library:

import pika

# Connecting to RabbitMQ
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()

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

# Sending a message
channel.basic_publish(
    exchange='',
    routing_key='task_queue',
    body='Hello RabbitMQ!',
    properties=pika.BasicProperties(delivery_mode=2)  # Make the message persistent
)

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

RabbitMQ is well-suited for distributed systems where it is necessary to offload main processes and ensure reliable message delivery.
