<li>What are default exchanges used for (anonymous queues?)</li></blockquote><div><br></div><div>There is only one default exchange. It has one special property: every queue is automatically bound to it</div><div>with the same routing key as queue name. This gives developers a way to "publish directly to a queue".</div>
<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><li>How many exchanges are "normal" </li></blockquote><div><br></div><div>However many you need.</div>
<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><li>How many queues are "normal"</li></blockquote><div><br></div><div>Unless you go into hundreds of thousands or millions, it is all fine. For larger numbers, you'll have to use</div>
<div>a cluster of rabbits. What matters is message rates and how large the backlog can grow during peak load time.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<li>Are queues usually very general or very specific in nature</li></blockquote><div><br></div><div>It is more common to see queues separated by purpose rather than having one queue being used</div><div>by all kinds of consumers.</div>
<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><li>Do workers/consumers typically consume from more than one queue or would they consume from a set of related queues</li>
</blockquote></div><br>"Consumer" is a somewhat overloaded term. Consumers in the AMQP 0.9.1 sense can only use one queue. Applications that<div>primarily consume and process messages can use any number of queues.</div>
