Have you ever noticed that execution plans changed? Is your performance suffering due to the change? If so, Automatic Plan Correction is for you. In our previous blog post, we identified scalar function improvements,parameter sniffing and data skew. In this post, we are going to show you how SQL Server 2017 can automatically help improve your performance. This is done by changing executions plans to improve your performance.
How does Automatic Plan Correction work?
Great question. Go ahead and watch the short video below to see for yourself.
If you found this page you most likely either found yourself in the middle of a SQL Server parameter sniffing and/or data skew issue and have no idea how to get yourself out of this hole. In the eight-minute video below we go over exactly what parameter sniffing and data skew is and how you can identify it on your own.
SPOILER ALERT: Parameter sniffing is mostly an amazing thing that saves tons of CPU cycles. Like many DBA tasks, this usually only gets attention when expectations are not met. Most likely you have these issues in your database without even knowing it. See a real-world case where data skew was resolved with a customer using SQL Server 2017 without changing any code.
Learn how to identify parameter sniffing and data skew and fix it on your own.
How do we fix SQL Server parameter sniffing?
Now that you know what parameter sniffing and data skew is our next blog post will go over using Query Store and Automatic Tuningto enhance your performance automatically or manually. This will resolve queries that regressed due to parameter sniffing.
