Reading Order
You do not have to read these in order, but this sequence is the fastest path from performance fundamentals into real query-tuning decisions.
Start with the access-path foundations behind seeks, scans, and composite index design.
Then learn how to confirm what the optimizer actually chose for a real query.
Use this to spot the query shapes that sabotage good indexes and create expensive plans.
Move into the broader checklist once the core plan-reading concepts are in place.
Finish with a concrete high-scale bottleneck where indexing, sorting, and pagination all intersect.
