What does the Buffer prefix help achieve?

The Buffer prefix is used in the context of QlikView and Qlik Sense to manage QVD files efficiently, particularly in relation to automatic generation and maintenance. When utilized in a script, the Buffer prefix enables the user to create a QVD file that stores the results of a load operation automatically. This means that the data can be reused in future sessions without requiring a re-load from the original data source, thus optimizing data retrieval performance and saving time.

By automating the process of QVD creation and maintenance, the Buffer prefix ensures that data is current and readily available, thereby enhancing the overall efficiency of data workflows in Qlik applications. This functionality is particularly useful in scenarios where datasets are frequently updated or reused, as it simplifies the data pipeline.

This context helps clarify why options related to creating new tables, storing temporary data, or optimizing data visualization do not fit within the primary purpose of the Buffer prefix. These functions are more aligned with other specific operations and prefixes or are handled by other features in Qlik’s data processing capabilities.
