Last weekend I had the pleasure to attend the excellent FOSDEM conference in Brussels, Belgium. I indulged aplenty in pancakes with Nutella, a Belgian beer or two, and some truly interesting presentations. MySQL had a lecture hall for itself the whole weekend, and the booth conveniently located outside. Stickers and robots were handed out, or at least so I’m told. By the time I got to the booth, around 10 am or so, they had already run out! I debuted a presentation on the query rewrite plugin API and how to write your own plugin. The slides are here, and thank you for using MySQL!
