I had the honor of speaking at the wonderful event - Data Platform Summit 2020. This event was very well-organized and provided a great experience for attendees. The organizers thought about everything and paid attention to the smallest details. Well done!
My session was about analyzing execution plans. I demonstrated a lot of stuff, like how to interpret the operator costs, which operator properties to pay attention to, and why you should avoid table variables and scalar functions.
For those of you who attended the session (and also for those of you who didn't), I promised the make all the session materials available for download. So here it is.
If you have any questions about execution plans, please use the comments below.
See you at the next Data Platform Summit!
