Sounds interesting.
I have some time ago started a wiki page http://rhq-project.org/display/RHQ/Ideas+about+Caching
and so on, which also talks about metrics.
Management summary: RAM is so cheap, lets put the stuff into Infinispan.
That page also talks about other areas, where caching stuff in memory will help us a lot with our
current performance issues.
Michael: we have a lot of very expensive recursive queries in our code, that take a huge amount of cpu
on Oracle - even if the tables (especially resources) fits completely in memory. Those tables warrant
re-structuring and even pre-calculation of some queries.
