Query Store

When the query store was a new product I was really not sure how to actually the product until I implemented it in the real world for the first time. Query store is an amazing feature if we know how to use it and how to translate the feature to success. Till today, I see lots of users who have enabled query stores for their database but have no idea how to use it efficiently. Many people just use it as a query repository and that is just an extremely limited use of this product.

There can be many different usages of the Query Store but I have been using it for three major things.

  1. After SQL Server upgrade tracking Query regressions
  2. Fixing parameter spoofing issues
  3. Tracking wait statistics for specific queries

Query Store Reports

Though the query store may look complicated the easiest part of the query store is actually query store reports. There are few readymade reports which you can use it identify the troublesome queries and also remedy their fixes.

  • Regressed Queries
  • Overall Resource Consumption
  • Top Resource Consuming Queries
