What is the primary use of the Hyper API in Tableau?

The primary use of the Hyper API in Tableau is to manipulate and write data to extract files. The Hyper API is designed specifically to interact with Tableau’s Hyper data engine, allowing developers to create, modify, and manage data extracts programmatically. This capability is essential for automating workflows that involve preparing data for analysis, especially in scenarios where large datasets are processed or updated frequently.

By utilizing the Hyper API, users can load data from various sources into Tableau's Hyper format, which optimizes performance and enables efficient data retrieval during analysis. This is particularly important for organizations that rely on large-scale data management, as it helps streamline the process of creating updated extracts without requiring manual intervention through the Tableau Desktop interface.

In contrast, other options address functionalities found in other components of Tableau or require different tools and approaches. For example, retrieving data from external databases involves using connectors rather than the Hyper API. Similarly, creating and managing user accounts pertains to Tableau Server or Tableau Cloud administration, not the Hyper API's functions. Lastly, notifying users of workbook changes involves notification settings and alerts rather than manipulation of data extracts.
