AI Technical Summary
Traditional external staging areas require secret security certificate exchanges in cloud data warehouses, which leads to security vulnerabilities and data leakage risks. Furthermore, access control is not granular enough and cannot be used in multiple file paths.
By employing certificateless external staging area objects, and through the integration between the network-based data warehouse system and the cloud storage provider system, proxy identity objects and cloud identity objects are used to achieve data loading and unloading without exchanging security certificates, combined with fine-grained access control mechanisms.
It enables secure loading and unloading of data within cloud storage provider systems, prevents data leaks, improves the granularity of access control, and supports the use of multiple file paths.
