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,

Getting started with RabbitMQ-working queue and rabbitmq 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
