In the previous tutorial we created a work queue. The assumption behind a work queue is that each task is delivered to exactly one worker. In this part we'll do something completely different -- we'll deliver a message to multiple consumers. This pattern is known as "publish/subscribe". ...
having multiple consumers on a single queue. The scenario I'm using Rabbit-MQ for is as follows: - Many producers send messages to a direct exchange that end up in a "job" queue - Many single-threaded consumers are listening on a single job queue using basic_consume - When...

When wanting to deliver the same message to multiple subscribers users currently have to bind a dedicated queue for each consumer. If the number of consumers is large this becomes potentially inefficient, especially when wanting persistence and/or replication. Streams will allow any number of consumer...
application scenario: It takes 10s to process an order, and multiple orders can be placed in the message queue at the same time, and then multiple consumers can be processed at the same time. This is parallel, not the serial situation of a single consumer ...
Queues are single-threaded in RabbitMQ. You will achieve better throughput on a multi-core system if you have multiple queues and consumers and if you have as many queues as cores on the underlying node(s). The RabbitMQ management interface collects and calculates metrics for every queue in ...
Use multiple queues and consumers Queues are single-threaded in RabbitMQ, and one queue can handle up to about 50 thousand messages. You will achieve better throughput on a multi-core system if you have multiple queues and consumers and if you have as many queues as cores on the underlying...
The RabbitMQ - Queue dashboard provides an at-a-glance view of the state of your queues in your RabbitMQ clusters. Use this dashboard to: Monitor number of consumers on queues Gain insights into pushing messages rate for queues of your RabbitMQ cluster. ...
“5”, so let’s follow the process flow, assuming that we’ve started each Consumer in order of 1 through 5. This is important because in situations where multiple Consumers are listening to a Queue, RabbitMQ will prioritise delivery of messages in the same order that the Consumers started...
