Message queues enable asynchronous communication, which means that the endpoints that are producing and consuming messages interact with the queue, not each other. Producers can add requests to the queue without waiting for them to be processed. Consumers process messages only when they are available.

Queues have the advantages of being able to handle multiple data types and they are both flexible and flexibility and fast. Moreover, queues can be of potentially infinite length compared with the use of fixed-length arrays.
What is a Message Queue broker?
In order to provide reliable message storage and guaranteed delivery, message brokers often rely on a substructure or component called a message queue that stores and orders the messages until the consuming applications can process them.
Does message queue decrease overall performance?

How does Rabbit MQ work?
In actual case, working of RabbitMQ is that producer sends message to “EXCHANGE” and exchange pushes it to multiple queues and workers get message from queues to which it has binded with. Now instead of publishing directly to queue, producer now publish messages to exchange.Why is MQ used?
MQ simply stands for Message Queue. You would use one when you need to reliably send a inter-process/cross-platform/cross-application message that isn’t time dependent. The Message Queue receives the message, places it in the proper queue, and waits for the application to retrieve the message when ready.
