You might be able to get a very, very small cluster to run on MySQL.<br>
This will be less of an issue with Mongo since writes are faster with Mongo.<br>
<br>
I wonder if anyone runs a cluster of some size with ceilometer though. (And what they use)<br>
During a poll at the operators meetup there was no one running it properly in production due to performance issues..<br>
<br>
We decided we only wanted to have some graphs of instances and do not need other functionality so we build a plugin to put it in graphite: <a href="http://engineering.spilgames.com/using-ceilometer-graphite/" target="_blank">http://engineering.spilgames.com/using-ceilometer-graphite/</a><br>
