The user does not regularly alter the Context Filter since changing it requires the database to be recomputed and the temporary table to be rebuilt, delaying performance.
Tableau produces a temporary table when we set a dimension to context, which requires a reload every time the view is opened. The temporary table produced for Excel, Access, and text data sources is in Access table format. We need the authorization to create a temporary table on our server for SQL Server, MySQL, and Oracle data sources. Temporary tables are not generated for a multidimensional data source, or cubes, and Context Filters identify which Filters are independent and which are dependent.
