<div class="moz-cite-prefix">I'd look at what Keystone did fronting
the various Key Value stores woth Dogpile. Then the same APi from
Keystone can be backed by any Dogpile implementation. We support
Reddis, Memcached, with Cassandra and Mongo both somewhere in
there (not certain their state)<br>

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 moz-do-not-send="true"
