Applications May Pick Queue Names Or Ask The Broker To Generate A Name For Them.

After logging into rabbitmq web management portal, navigate to queues tab and click on the queue (demoqueue) which you want to publish messages like as shown below. Each exchange type routes the message differently using different parameters and bindings setups. If you observe above example, we are publishing a message (direct message) to queue by passing required parameters like exchange, routing key, properties and message to basicpublish method.when we execute above c# program, we will get the result like as shown below.

Secondly, How Many Queues Can Rabbitmq Handle?

Similarly, it is asked, how does rabbitmq. With the default topic exchange patterns are only accepted when binding queues to exchanges. In rabbitmq, topic exchange will perform a wildcard match between the routing key and the routing pattern specified in the binding to publish a messages to queue.
