Two days ago, on the 24HOP Russia I was talking about the Query Processor internals and joins. Despite I had three hours, I felt the lack of time, and something left behind, because it is a huge topic, if you try to cover it in different aspects in details. With the few next articles, I’ll try to describe some interesting parts of my talk in more details. I will start with Hash Join execution internals.
This post is for the absolutely geeky people. For those that will not afraid when they hear: “query transformation rules”.
