What is the primary function of the Delta Share Protocol?

The primary function of the Delta Share Protocol is to enable open access to data products without the need to physically move data. This protocol is particularly valuable for data sharing and collaboration, as it allows users to securely access and use shared data from various sources while maintaining control over the original data location. With Delta Share, organizations can provide permissions and govern access to their datasets in a way that promotes privacy and security, while still supporting analytical needs.

The emphasis on not requiring data movement is significant because it alleviates concerns related to data duplication, inconsistency, and the overhead associated with transferring large datasets. This aspect of the protocol is crucial for organizations that wish to leverage data analytics and machine learning while keeping data governance practices intact.

Alternative choices relate to capabilities that, while important in the data management landscape, do not accurately represent the core function of Delta Share. For instance, simply copying data across different platforms without the benefits of secure access or governance doesn't capture the uniqueness of Delta Share. Similarly, storing data locally or encrypting it before sharing address different aspects of data management rather than focusing on the open access characteristic that Delta Share Protocol uniquely provides.
