Troubleshoot slow-performing queries and make them run faster.
Database administrators and SQL developers are constantly under pressure
to provide more speed. This new edition has been redesigned and
rewritten from scratch based on the last 15 years of learning,
knowledge, and experience accumulated by the author. The book Includes
expanded information on using extended events, automatic execution plan
correction, and other advanced features now available in SQL Server.
These modern features are covered while still providing the necessary
fundamentals to better understand how statistics and indexes affect
query performance.
The book gives you knowledge and tools to help you
identify poorly performing queries and understand the possible causes
of that poor performance. The book also provides mechanisms for
resolving the issues identified, whether on-premises, in containers, or
on cloud platform providers. You’ll learn about key fundamentals, such
as statistics, data distribution, cardinality, and parameter sniffing.
You’ll learn to analyze and design your indexes and your queries using
best practices that ward off performance problems before they occur.
You’ll also learn to use important modern features, such as Query Store
to manage and control execution plans, the automated performance tuning
feature set, and memory-optimized OLTP tables and procedures. You will
be able to troubleshoot in a systematic way. Query tuning doesn’t have
to be difficult. This book helps you to make it much easier.
