Describe your experience with message queue systems and their integration into applications.

In my experience working with message queue systems (such as RabbitMQ, Kafka, Redis Streams), I have used them to organize asynchronous interaction between application components.

Main tasks solved with message queues:

• Offloading main application threads, passing tasks for background processing.
• Ensuring reliable message delivery and sequential processing.
• Scaling and load distribution among multiple consumers.

Example of integration with Python (using the pika library for RabbitMQ):

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 World!',
                      properties=pika.BasicProperties(delivery_mode=2))  # persistent message

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

In the application, the consumer listens to the queue and processes messages, which allows separating task generation from their execution.
