Query Store started as a feature used to help data professionals troubleshoot changes in query performance. It has now become the underlying foundation for a suite of intelligent query processing (IQP) features. In this session we will cover the most important details you know about Query Store: proper configuration, best practices, and how to use it - both through the UX and with T-SQL. We'll step through a series of demos based on problems encountered in production environments so that you can immediately implement it for your SQL databases.
