# Create a Microsoft Fabric OneLake File Federation Data Stream (Beta)

Start the flow of data by creating a data stream for your Microsoft Fabric OneLake data source. The data stream creates a data lake object (DLO) in Data 360 that you can map to the Customer 360 Data Model to use across Data 360.

This connector supports file federation.

**note:** This feature is a Beta Service. A customer may opt to try a Beta Service in its sole discretion. Any use of the Beta Service is subject to the applicable Beta Services Terms provided at [Agreements and Terms.](https://www.salesforce.com/company/legal/agreements/) If you have questions or feedback about this Beta Service, contact the Data 360 Connector team at [datacloud-connectors-beta@salesforce.com.](mailto:datacloud-connectors-beta@salesforce.com)
