Apply the new Query Store feature to identify and fix poorly performing
queries in SQL Server.
Query Store is an important and recent feature in SQL Server that
provides insight into the details of query execution and how that
execution has changed over time. Query Store helps to identify queries
that aren't performing well, or that have regressed in their
performance. Query Store provides detailed information such as wait
stats that you need to resolve root causes, and it allows you to force
the use of a known good execution plan. With SQL Server 2017 and later
you can automate the correction of regressions in performance.
Query Store for SQL Server 2019 helps you protect your database's
performance during upgrades of applications or version of SQL Server.
The book provides fundamental information on how Query Store works and
best practices for implementation and use. You will learn to run and
interpret built-in reports, configure automatic plan correction, and
troubleshoot queries using Query Store when needed. Query Store for
SQL Server 2019 helps you master Query Store and bring value to your
organization through consistent query execution times and automate
correction of regressions.
