MySQL sys version 1.0.1 released

I’ve just released the 1.0.1 version of the MySQL sys schema. It contains a few bug fixes (including a contribution from Joe Grasse, thanks Joe!), and a number of new helper procedures around viewing and altering configuration for consumers and instruments, contributed by the MySQL QA team, as they’ve started to incorporate more Performance Schema trace data in to their automated testing.

Next up is the 1.1.0 release, that also includes a bunch of new host summary views that were contributed by Arnaud Adant (of the MySQL Support team). I have a number of new things in development to add as well before then though.

Let me know if there are things you’d like to see as well, maybe I can find time to work on those too.


MySQL Tech Day, Paris, Slides

First Dimitri presented some recent benchmark findings:

Then I got my turn to speak for a few hours around Performance Schema and the MySQL sys schema:

Visible there on the left is also Marc Alff, the principle developer of Performance Schema, who was also able to interject some great points for people as well.

My presentation was a super-set of a few of my previous ones, but updated and with a little added content here and there (particularly around the MySQL sys updates from ps_helper), so it’s pretty long (I had 3 hours to fill), but probably the most complete that I’ve done.

Here are the slides:
