I am just starting to use RabbitMQ and AMQP in general.

 - I have a queue of messages
 - I have multiple consumers, which I would like to do different things with the **same message**. 

Most of the RabbitMQ documentation seems to be focused on round-robin, ie where a single message is consumed by a single consumer, with the load being spread between each consumer. This is indeed the behavior I witness. 

An example: the producer has a single queue, and send messages every 2 sec:

    var amqp = require(&#39;amqp&#39;);
    var connection = amqp.createConnection({ host: &quot;localhost&quot;, port: 5672 });
    var count = 1;

    connection.on(&#39;ready&#39;, function () {
      var sendMessage = function(connection, queue_name, payload) {
        var encoded_payload = JSON.stringify(payload);  
        connection.publish(queue_name, encoded_payload);
      }
  
      setInterval( function() {    
        var test_message = &#39;TEST &#39;+count
        sendMessage(connection, &quot;my_queue_name&quot;, test_message)  
        count += 1;
      }, 2000) 
  

    })

And here&#39;s a consumer:


    var amqp = require(&#39;amqp&#39;);
    var connection = amqp.createConnection({ host: &quot;localhost&quot;, port: 5672 });
    connection.on(&#39;ready&#39;, function () {
      connection.queue(&quot;my_queue_name&quot;, function(queue){
        queue.bind(&#39;#&#39;); 
        queue.subscribe(function (message) {
          var encoded_payload = unescape(message.data)
          var payload = JSON.parse(encoded_payload)
          console.log(&#39;Recieved a message:&#39;)
          console.log(payload)
        })
      })
    })

If I start the consumer twice, **I can see that each consumer is consuming alternate messages in round-robin behavior. Eg, I&#39;ll see messages 1, 3, 5 in one terminal, 2, 4, 6 in the other**.

My question is: 

 - Can I have each consumer receive the same messages? Ie, both consumers get message 1, 2, 3, 4, 5, 6? What is this called in AMQP/RabbitMQ speak? How is it normally configured?

 - Is this commonly done? Should I just have the exchange route the message into two separate queues, with a single consumer, instead?
