Tracking Performance History with Query Store

This chapter will introduce the Query Store, which is effectively a flight recorder for the SQL Database Engine T-SQL executions, allowing performance tracking over time and analysis of workload trends through rich-UI reports that are included with SQL Server Management Studio (SSMS).

We will also see how Query Store integrates with Query Plan Comparison, which was covered in Chapter 9, Comparative Analysis of Query Plans, for a complete user interface (UI)-driven workflow for query performance insights. This chapter covers the following topics:

  • Introducing the Query Store
  • Tracking expensive queries
  • Fixing regressed queries
  • Features that rely on the Query Store
