The 'data_connections' table to gain insights into connections and performance of published data sources The
'data_connections' table in the Tableau repository schema is critical for tracking the performance of published data sources. It provides detailed information on each connection made to the data sources, offering insights into how these data sources are being accessed and utilized, which is crucial for understanding and optimizing their performance. Option A is incorrect because the 'users' table, while identifying users, does not provide specific information on data source performance. Option C is incorrect as the 'background_tasks' table focuses on scheduled tasks and does not offer detailed insights into real-time data source performance. Option D is incorrect because the 'server_usage' table provides a broad overview of server activity but does not offer the granular details required for monitoring specific data source performance.
