1.2.4. OneLake Settings and Data Access
💡 First Principle: OneLake settings control how data is stored, accessed, and governed across the tenant. These settings have security and performance implications.
Key OneLake Settings
| Setting | Purpose | Default |
|---|---|---|
| Users can access data via ADLS APIs | Allow Azure Data Lake Storage Gen2 API access | Enabled |
| Users can sync data via OneLake file explorer | Desktop sync client access | Enabled |
| Users can create shortcuts | Allow shortcut creation | Enabled |
| Tenant-level data sharing | Cross-tenant data sharing | Disabled |
⚠️ Common Pitfall: Disabling ADLS APIs without understanding impact. Many tools (Azure Databricks, external Spark clusters) rely on ADLS APIs to access OneLake data.
