we need to eventually support MySQL. See forum threads: http://forums.rhq-project.org/viewtopic.php?f=5&t=25 http://forums.rhq-project.org/viewtopic.php?f=5&t=27 http://forums.rhq-project.org/viewtopic.php?f=5&t=28
"support" won't likely make the 1.1 release. If we get the CLA out of the way, hopefully we can integrated the contributions for beta support.
This bug was previously known as http://jira.rhq-project.org/browse/RHQ-141
While this may become easier with more and more data moved off the RDBMS into the storage nodes, I doubt that we will address this task any time soon. I am closing it though. If someone wants to contribute this, please open a pull-request on https://github.com/rhq-project/rhq and open a new BZ with the link to the PR attached.
