Description

### Customer Managed Keys (CMK) Support on Fabric Warehouse**Customer Managed Keys (CMK) support on Fabric Warehouse** allows customers to use their own encryption keys stored in Azure Key Vault or Managed HSM to protect data at rest within Fabric workspaces. This feature ensures that all persistent customer data--including OneLake storage and SQL metadata--is encrypted with customer-controlled keys, providing enhanced security, compliance, and key lifecycle management. CMK on Fabric Warehouse is a critical component of Fabric workspace encryption, enabling customers to maintain full ownership and control of their encryption keys across the Fabric platform.
