Yeah, that's probably a decent solution too.<div>Another similar tool is doozer <a href="https://github.com/ha/doozer" target="_blank">https://github.com/ha/doozer</a></div><div>I've never used either of them though.</div>

<div>How about a deamon constantly pull the information from<br></div><div>command line "rabbitmqctl status" ?</div><div>I mean comparing to a plugin, will it cause any performance impact to rabbit-server?</div>

This is also a pretty natural thing to do with a system like Zookeeper<br>
from the Hadoop project, although it would require Rabbit to grow something<br>
like a plugin that either had an Erlang Zookeeper client, or used a port<br>
or jinterface to the native C or Java Zookeeper clients, to do the necessary<br>
work...<br>

no, you have to manually administer the dns (or automatically through<br>
some heartbeat stuff interacting with your dns provider api.. )<br>
<br>
i don't know how the client implementations are, but they could try to<br>
connect to the first A record, if that fails try the next one and so<br>
forth.. (like the way many web browsers does)<br>
