Session 10: Parallelism in SQL Server

This session provides an overview of parallelism in SQL Server. It covers the basics of parallel query execution, including partitioning data and distributing it among CPUs for simultaneous operations. The presentation highlights the benefits of parallelism for large queries, especially in data warehouse workloads, but also notes the overhead and potential bottlenecks it can introduce. Practical examples demonstrate creating data for parallelism, generating parallel execution plans, and comparing performance with and without parallelism. The presentation concludes with troubleshooting tips for parallelism-related performance issues
