You’ll learn about per-query wait statistics and session-based wait statistics, and the types of problems they each can help you solve. The different wait types are categorized by their area of impact, including CPU, IO, Lock, and many more..The book presents clear examples to help?you gain practical knowledge of why and how specific wait times increase or decrease, and how they impact your S

Preemptive Wait Typesmanage that thread. While SQL Server is waiting for the preemptive thread inside the Windows operating system to complete, SQL Server will record a wait on a preemptive wait type. Figure 11-1 shows a graphical representation of this behavior.

The Query Storermed, and what execution plan was used during execution of the query. While the Query Store did not initially expose wait statistics that were encountered during query execution, the release of SQL Server 2017 included that much awaited addition.

Background and Miscellaneous Wait Typeshese background processes. While these background wait types are not directly related to performance problems, they frequently have the highest wait time and will show up at the top of the wait time list when you query the top wait types ordered by wait time.
