Query Tuning Mastery: Workspace Memory Internals
Large, complex queries need memory in which to work--workspace memory--and understanding the how's, when's, and why's of this memory can help you create queries that run in seconds rather than minutes.
As SQL Server professionals, we often think of memory in vague, instance-level terms: buffer pool, procedure cache, Virtual Address Space, and so on. But certain tasks require a more in-depth focus, and query tuning is one of them. Large, complex queries need memory in which to work--workspace memory--and understanding the how's, when's, and why's of this memory can help you create queries that run in seconds rather than minutes. This session will give you an in-depth understanding of how the optimizer makes its query memory decisions, with lots of tips and tricks along the way to help you guide the process for top performance. If you work with large queries and are serious about achieving scalability and consistently great performance, you owe it to yourself to attend this session.
