You plan to create a database. The database will be used by a Microsoft .NET application for a special event that will last for two days. During the event, data must be highly available. After the eve

Max Degree of Parallelism (MAXDOP) controls the number of processors used for parallel query execution within a single instance but does not isolate workloads between different applications or prevent resource contention from existing workloads.

Resource Governor is a SQL Server feature that manages workload and resource consumption, but it requires SQL Server Enterprise Edition, which increases costs rather than minimizing them, making it a less cost-effective choice.

Windows System Resource Manager (WSRM) is a Windows Server feature for managing CPU and memory allocation across processes, but it was deprecated starting with Windows Server 2012 and does not provide the database-level isolation needed for this scenario.

Processor affinity allows you to bind a SQL Server instance or workload to specific CPU cores, effectively isolating the temporary event database's processing from existing applications running on other cores. This ensures high availability of CPU resources for the event without additional licensing or infrastructure costs, and the configuration can be reversed after the two-day event when the database is deleted.
