<div class="moz-cite-prefix">Following is my understanding:<br>
usage:<br>
scheduler queue is used for compute api server. For example of
nova boot, API server will send a msg to scheduler queue for a
booting<br>
scheduler_<b
style="font-family:Verdana,sans-serif;font-weight:normal"><font>fanout_xxxx
is used for service<b>s to report service capability. For
example, nova compute </b></font></b>will use
scheduler_fanout to publish its capabilities.<br>
<br>
scheduler.{hostname} seemingly is not used now.<br>
we can deploy many schedulers into a Openstack cloud. All the
schedulers will listen on scheduler msg queue. AMQP server
(rabbitmq) will adopt round robin way to <br>
dispatch the msg to these schedulers. But since the capabilities
are fan outed, all the schedulers can receive these capabilities.<br>
