Data roles, also called entitlements, are sets of permissions defined per virtual database that specify data access permissions (create, read, update, delete). Data roles use a fine-grained permission system that Teiid Spring Boot will enforce at runtime and provide audit log entries for access violations.

Before you apply data roles, you might want to restrict source system access through the fundamental design of your virtual database. Foremost, Teiid Spring Boot can only access source entries that are represented in imported metadata. You should narrow imported metadata to only what is necessary for use by your virtual database.

If data role validation is enabled and data roles are defined in a virtual database, then access permissions will be enforced by the Teiid Spring Boot server. The use of data roles may be disabled system wide by removing the setting for the teiid subsystem policy-decider-module. Data roles also have built-in security functions that can be used for row-based and other authorization checks.
