RabbitMQ by Example: Multiple Threads, Channels and Queues

RabbitMQ by Example: Multiple Threads, Channels and Queues

I just read&nbsp;<a href="http://www.rabbitmq.com/api-guide.html" target="_blank">RabbitMQ's Java API docs</a>, and found it very informative and straight-forward. The example for how to set up a simple&nbsp;<code>Channel</code>&nbsp;for publishing/consuming is very easy to follow and understand. But it's a very simple/basic example, and it left me with an important question:&nbsp;<strong>How can I set up 1+&nbsp;</strong><code><strong>Channels</strong></code><strong>&nbsp;to publish/consume to and from multiple queues?</strong>

I just read RabbitMQ's Java API docs, and found it very informative and straight-forward. The example for how to set up a simple Channel for publishing/consuming is very easy to follow and understand. But it's a very simple/basic example, and it left me with an important question: How can I set up 1+ Channels to publish/consume to and from multiple queues?

Let's say I have a RabbitMQ server with 3 queues on it: loggingsecurity_events and customer_orders. So we'd either need a single Channel to have the ability to publish/consume to all 3 queues, or more likely, have 3 separate Channels, each dedicated to a single queue.

On top of this, RabbitMQ's best practices dictate that we set up 1 Channel per consumer thread. For this example, let's say security_events is fine with only 1 consumer thread, but logging and customer_order both need 5 threads to handle the volume. So, if I understand correctly, does that mean we need:

  • Channel and 1 consumer thread for publishing/consuming to and from security_events; and
  • Channels and 5 consumer threads for publishing/consuming to and from logging; and
  • Channels and 5 consumer threads for publishing/consuming to and from customer_orders?

If my understanding is misguided here, please begin by correcting me. Either way, could some battle-weary RabbitMQ veteran help me "connect the dots" with a decent code example for setting up publishers/consumers that meet my requirements here? Thanks in advance!
