Discovering the Plan Cache
Execution plans are stored after execution in the plan cache. This metadata about how queries are executed can provide insight into how your SQL Server environment is functioning. By using XQuery to browse and search the plan cache you can find potential performance issues and opportunities to tune your queries. This information can be used to help reduce issues related to parallelism, shift queries from using scans to using seek operations, or discover exactly which queries are using what indexes. All of this and more is readily available through the plan cache. In this session we will explore the plan cache and start you on the road to discovery.
