As with most services there are two queues, but the scheduler has one extra:
1. The general round-robin queue. Any worker of that class can process the event. But, only one worker will handle the event. 2. The specific worker queue. Used when I want an event to go to a specific worker, for example: "I want Scheduler #2 to deal with this" 3. The fan-out queue. For sending atomic, non-critical information to all workers. The compute nodes send periodic capacity updates to all schedulers on this channel. Hope it helps! -S ________________________________ From: openstack-bounces+sandy.walsh=rackspace....@lists.launchpad.net [openstack-bounces+sandy.walsh=rackspace....@lists.launchpad.net] on behalf of 韦远科 [weiyuanke...@gmail.com] Sent: Tuesday, October 30, 2012 7:55 AM To: openstack mail list Subject: [Openstack] about nova-schedule queues hi all, I read into the source code for nova-scheduler and found there actually exists three msg queues, like "scheduler" "scheduler.node70" "scheduler_fanout_bd738fedcdf344d9bb3cb580657f54e0". what's the functions for each queue and are there connections?? thanks,
