Python Operation Rabbimq

RABBITMQ is a complete, reusable enterprise messaging system based on AMQP. He follows the Mozilla Public License open source agreement.

MQ is all called the message queue, and Message Queuing (MQ) is an application-to-application communication method. Applications communicate by reading and writing messages to and from the queue (data for the application), without requiring a dedicated connection to link them. Message passing refers to the process of communicating between programs by sending data in a message, rather than by directly invoking each other, and directly invoking techniques such as remote procedure calls. Queuing refers to an application communicating through a queue. The use of queues removes the requirement that both the receiving and sending applications execute concurrently.

the module name for the Puthon operation RABBITMQ is: PikaHttps://github.com/pika/pika understand the producer consumer model through queue before operating RABBITMQ

Producer Consumer Model

For RABBITMQ, production and consumption no longer target a queue object in memory, but rather a message queue implemented by RABBITMQ server on a single server.
