middleware is mainly used for decoupling between components, the sender of the message does not need to know the existence of the message consumer, and vice versa. The main features of AMQP are message-oriented, queue, routing (including point-to-point and publish/subscribe), reliability, and security. RABBITMQ is an open-source AMQP implementation that is written in Erlang and supported by a variety of clients such as Python, Ruby,. NET, Java, JMS,

Then we will display the production ID message: [x] Sent 'Hello World! '
The production process stops every execution.
Then start the consumption process:
$ python receive.py [*] Waiting for messages. To exit press CTRL+C [x] Received 'Hello World!'
Here we will find the message 'Hello World! ', So that a production consumption is completed.

Finally, the message is removed from the queue. If the consumer exits unexpectedly, if there are other consumers, then the message in the queue will be sent to other consumers, if not, and so on when consumers start sending again. On t

What is a work queue?
A work queue is a processing method to avoid waiting for a number of resources or time-consuming operations. We encapsulate the task as a message and send it to the queue. The consumer keeps pulling the task from the backend and executing it. When multiple consumer worker processes are run, tasks in the queue are shared among eac
