Billing is built around consumption, aligning costs with actual database activity rather than reserved infrastructure, which can be helpful for variable or seasonal applications. Fabric Databases support vector data and retrieval-augmented generation patterns out of the box, allowing applications to store embeddings, run semantic searches, and connect directly to Fabric's AI services. Because operational tables and vector indexes live within the same managed environment, organizations can build intelligent applications—such as recommendation systems, conversational interfaces, and anomaly detection tools—on top of their existing datasets while keeping everything synchronized through OneLake. Enterprise-grade security controls apply consistently across SQL and Cosmos DB–style databases, including role-based access, encryption options, and integration with Microsoft Entra ID for identity management. Because the databases are native to Fabric, they inherit centralized policy management, auditing, and data lineage capabilities, making it easier for organizations to demonstrate compliance for regulated workloads that involve sensitive data.
