Delta Tags for QlikView and Qlik Sense

When working with large datasets in QlikView and Qlik Sense, it's important to ensure the backend data processing jobs (Extracts and Transforms) perform efficiently, by following best practices to reduce execution time and keep resource usage at a minimum. One of the best practices recommended for efficient data
