Using Query Store

Justin Goodwin looks at Query Store in SQL Server 2016:

You can see that our problem query is incredibly easy to find in the top left window based on total duration. Also notice that in the top right Plan summary window, there is currently only one available plan for the query (plan_id 49).

We need to figure out how we can get our ‘good plan’ using Trace Flag 9481 as an available plan that we can force using the Query Store.

The cardinality estimator change in SQL Server 2014 wasn’t perfect, but when you can fix individual plans like this, it makes SQL Server much more powerful.
