2.2.4. OneLake Settings and Data Access
💡 First Principle: OneLake settings act as the master switches controlling how data can flow into and out of your organization's data lake. Flip the wrong switch, and you might accidentally expose internal data externally—or break all your external integrations. These are tenant-level decisions with organization-wide consequences.
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 |
⚠️ Exam Trap: Disabling ADLS APIs breaks many external tools. Azure Databricks, external Spark clusters, and many third-party tools rely on ADLS APIs to access OneLake data. Understand the downstream impact before changing this setting.
