An Advanced SQL Server Query Profiling Technique

In this video, I delve into advanced query profiling techniques using SQL Server's built-in dynamic management views and actual execution plans to gain insights during query execution. We explore two different versions of a query-one serial and one parallel-to observe how they behave differently in terms of resource usage and performance. By examining the progress of operators through DMVs like 'sys.dm_exec_query_profiles', we can identify potential issues such as skewed parallelism or inefficient use of CPU resources, providing a deeper understanding of query execution and helping to pinpoint areas for optimization.
