Abstract
The Query Store was introduced originally in Azure SQL Database in 2015 and was first introduced to SQL Server in version 2016. The Query Store provides three pieces of functionality that you’re going to want to take advantage of. First, you get query metrics and execution plans, stored permanently in the database in structures that are easy to access so that you have good, flexible information about the performance of the queries on your system. Second, the Query Store creates a mechanism for directly controlling execution plan behavior in a way we’ve never had before. Finally, the Query Store acts as a safety and reporting mechanism for database upgrades that will enable you to protect your systems in new ways.
