Implement external services for real-time data processing and streaming before integrating with Tableau For handling large volumes of real-time data, using external services for initial processing and streaming can be more efficient, allowing Tableau to effectively integrate and visualize the processed data. Option A is incorrect as it's inefficient to use external services for storing all data, especially if not all of it is relevant for Tableau.
Option C is incorrect because relying solely on Tableau Server may not be efficient for large-scale real-time data processing. Option D is incorrect as external services can be valuable for both real-time and historical data, depending on the use case.
