While Brent taught many techniques, from everyday solutions to advanced once-in-a-while techniques for certain edge cases, my biggest takeaway was how Brent taught us to prioritize the low-hanging-index-tuning-fruit first. Typically, PAD_INDEX is not needed unless you have extremely unbalanced activity and are unable to rebalance the tree (meaning you need to achieve high availability). How would help if you are unable to regularly rebuild the index to enforce the on the non-leaf nodes of the index in the first place?Lab 1: Brent's Solution (85:02) How SQL Server 2017, 2019, and 2022 Try to Fix Queries Automatically The Tuning Robots in SQL Server 2017, 2019, and 2022 (51:27) Lab 4: Brent's Solution (132:28) Artisanal, Hand-Crafted, Specialized Index Types Filtered Indexes, Indexed Views, and Computed Columns (43:22) Watch How to Think Like the Engine and Fundamentals of Index Tuning.
