Bruce Momjan’s talk at PG Open will be replayed in Chicago – stay tuned!

Once again, I did’t write more about PG Open, although I had grand plans. But there were so many interesting talks, that I am still going to write about them, even though it’s already 3 weeks past the conference.

One talk I really enjoyed, was Bruce Momjian “The Window Magic“. You can find the presentation here.

That’s what I really liked about it. Window functions are hard. Seriously. This is one of those things, where you know there are options and answers to everything, but figuring out how to do this takes so long that you almost do not want to do this. What I absolutely love about this presentation is the fact, that it starts from the very basic example, and then adds one feature after another, and each time it is one easy – and logical! – step. And the amazing thing is, that Bruce manages to make sense out of literally each and single option, and they all make sense! None of them looks artificial or “why anybody would want to do that?”

Granted, it won’t be me, if I won’t have any comments :). The comment I had here was, that people should be warned that the window functions are resource consuming. The moment you really figure out this magic, you want to use it everywhere, even instead of min/max with group by! And the execution time will be very different in this case.

And now the best part – Bruce graciously suggested to bring his talk right here to Chicago!  Thereby we are moving the November PUG date – it is now scheduled for November 8.  Please RSVP to this event here.
