Take a deep dive into perhaps the single most important facet of query
performance--indexes--and how to best use them. Newly updated for SQL
Server 2022 and Azure SQL, this fourth edition includes new guidance and
features related to columnstore indexes, improved and consolidated
content on Query Store, deeper content around Intelligent Query
Processing, and other updates to help you optimize query execution and
make performance improvements to even the most challenging workloads.
The book begins with explanations of the types of indexes and how they
are stored in a database. Moving further into the book, you will learn
how statistics are critical for optimal index usage and how the Index
Advisor can assist in reviewing and optimizing index health. This book
helps you build a clear understanding of how indexes work, how to
implement and use them, and the many options available to tame even the
most large and complex workloads.
