In recent times, the processing power of a hardware system has been increased. This helps speed up the processing of large data and data warehouse queries, which can be termed as parallelism. By default, SQL Server utilizes the power of a multi-core hardware platform for a large amount of data management chores. Specifically, in query processing, the CPU is used extensively to perform multiple threads simultaneously. CPU can be a logical process or hyper-threaded cores. In this recipe, we will work on required tasks in implementing parallel query processing methods that can enable database or application tuning to help improve the performance.
