Persistência de Política
Apache Casbin stores policies through adapters. To keep the library lightweight, adapter code is separated from the main library (except for the default file adapter). We support third-party adapter contributions. See the full list of adaptadores for more information.
Policy Enforcement at Scale
Some adapters support filtered policy loading. This means Apache Casbin can load only a subset of policies from storage based on specified filters. This feature is useful for large-scale, multi-tenant applications where loading all policies at once would be inefficient.Role Manager
The role manager handles RBAC role hierarchy (user-role mappings) in Apache Casbin. It can load role data from Apache Casbin policy rules or from external sources like LDAP, Okta, Auth0, Azure AD, etc. To keep the library lightweight, role manager code is separated from the main library (except for the default one). See all available gerenciadores-de-funções.
