Query Store and Automatic Tuning in SQL Server [DBA]

Speaker: Erin Stellato

Duration: 75 minutes

Track: Perform

One of the most highly anticipated new features in the SQL Server 2016 release was Query Store. It's referred to as the "flight data recorder" for SQL Server because it tracks query information over time – including the text, the plan, and execution statistics. The addition of wait statistics information – tracked for each query plan – in SQL Server 2017 makes Query Store a tool that every data professional needs to know how to use, whether you're new to troubleshooting or someone who's been doing it for years. When you include the new Automatic Tuning feature in SQL Server 2017, suddenly it seems like you might spend less time fighting fires and more time enjoying a lunch break that’s not at your desk. 

In this session, we'll walk through Query Store with a series of demos designed to help you understand how you can immediately start to use it once you’ve upgraded to SQL Server 2016 or 2017. We'll review the different options for Query Store, look at the data collected (including wait stats!), check out how to force a plan, and dive into how you can leverage Automatic Plan Correction and reduce the time you spend on Severity 1 calls fighting fires.  It’s time to embrace the future and learn how to make troubleshooting easier using the plethora of intelligent data natively captured in SQL Server and SQL Azure Database.

Co-presenter: Dejan Krakovic, a Senior Software Engineer from Microsoft who helped develop Query Store and originally implement it for those 2 million (!) user databases in SQL Azure.
