Guy Glantser is an Israeli SQL Server guru with a ton of great presentations on YouTube. I’ve had the privilege of hanging out with him in person a bunch of times over the year, and I’ll always get excited to do it again. He’s not just smart, but he’s friendly and funny as hell.

Welcome to part twenty of the plansplaining series. It has been a long time since I last wrote a plansplaining post, partly because of my health, but also for a large part because I was out of ideas. But recently I decided to dig a bit deeper into a feature that was released in SQL Server 2017 and that I had so far not played with: SQL Graph.
