Fauna offers a cloud-native database that models security in the database, providing features such as access keys, tokens, delegation, and data expiry to ensure privacy and flexibility. The database's security model is applied to every query in the API, allowing for role-based access control (RBAC) and other access control patterns. Fauna's time-to-live document expiry feature can automatically remove old data, supporting GDPR principles like data minimization. The database also supports multi-tenancy, social content publishing, and collaborative workgroups, which are aligned with GDPR principles like data minimization, the right to access, and the right to erasure. By modeling application security constraints in the database using Fauna, developers can support GDPR principles and ensure privacy and flexibility in their applications.
