Why Scans are better than Seeks
Most DBAs design indexes and queries to avoid Scans and Lookups, and get adequate performance without knowing much more than that. In this talk, Rob Farley will demonstrate some of the differences between Scans and Seeks, breaking some of the preconceptions that people have about them, and investigating some of the impact they have around Joins, Parallelism and more. You'll see lots of queries and query plans, and leave with a much better understanding about what to look for in plans.
