Description

Adding User-Table Permission Cache

Introduce a cache for user-table permissions, with an option to control whether this feature is enabled or not, with the default setting being disabled. This feature is utilized when project-level Kerberos authentication is enabled and Hive table permission filtering is also enabled.
