From http://forge.mysql.com/worklog/task.php?id=4895 they will generate events for every row operation and then from http://forge.mysql.com/worklog/task.php?id=4816 support will eventually be added for summary tables. I want the summary tables first. I am skeptical that the per-event instrumentation can be done without a lot of CPU overhead. It will certainly have a lot of memory overhead to buffer events. And I want to have stats enabled all of the time for the summary tables. Have I read this correctly?

Many of the core developers (Serg, Kostja, et al) are pretty keen to see the object monitoring rather than file IO as well, so there's a lot of push to get this in there as well from inside too. Vote on the worklog if it fits your needs! :) Hey Mark,

It would be nice to know that performance stats aggregated by user and table are in the performance schema roadmap.

What else would you guys need, to be able to start feeding back patches? There's some great stuff in there, I think it's a real shame that the "wider community" misses out, and would love to see you guys working closer with us now that we are trying to open up with such vigor.
