A note to let you know that I will be at PASS this year and plan to give two talks (one in collaboration with a colleague of mine on the QP).
One will be a 500 level talk on how Update queries work – lots and lots of gory details. The other will be a 400 level talk (this is the collaboration talk) on how the QP team troubleshoots issues we see. So, lots of detailed techniques we use when evaluating problematic systems (things that you can do as well).
So, if you are considering going to Seattle in November for the PASS conference, now you have two reasons to consider going :). I hope to see you there.
