Fabric OneLake

Fabric OneLake shortcuts enable cross-workspace data sharing by creating virtualized pointers to Delta Parquet datasets, eliminating data duplication while maintaining unified governance and access control across the tenant-wide data lake.

OneLake architecture provides a tenant-wide hierarchical namespace organizing Delta Parquet files across workspaces, enabling scalable lakehouse designs with unified storage, governance, and direct REST DFS API access for file operations.

Configuring workspace identity in Fabric OneLake involves enabling the identity within workspace settings to authenticate cross-workspace access, allowing secure shortcuts and file operations across shared lakehouse datasets.

Yes, Fabric OneLake supports the REST DFS API for direct file operations on Delta Parquet data, providing programmatic access to manage hierarchical namespace files and authenticate using supported authentication models.

Monitoring V-Order optimization and caching in a Fabric OneLake lakehouse involves tracking file access patterns and query performance metrics to ensure optimal Delta Parquet read efficiency and cross-workspace data governance.

Use OneLake data access roles when you need granular governance over cross-workspace shared datasets, applying role-based access directly to Delta Parquet files and shortcuts beyond standard workspace-level permissions.
