# Microsoft OneLake

# Microsoft OneLake {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
The Microsoft OneLake connector provides read-only access to data and metadata in Microsoft OneLake.

A connection admin can set up a connection to Microsoft OneLake in the Zero Copy Connector Hub and grant data stewards access to this connection. Data stewards can then use the established connection to create a data fabric table and map data from Microsoft OneLake. This allows users to access
Microsoft OneLake data through the table list view or by using GlideRecord scripts. For details on creating data fabric tables and mapping data, see [Managing data fabric tables](https://www.servicenow.com/docs/vdLJlIcLw1vrKjAsL1R1Eg "Access data virtually from an external source or a local table on your instance using data fabric tables.").  
Important:  
The Microsoft OneLake primary connector is in preview. A primary connector in preview is developed and supported by ServiceNow, but is still being enhanced to include all planned functionality. While in preview, a connector may have limitations in platform support or available features.

A primary connector in preview is fully
functional for its documented scope and receives the same ServiceNow support as other primary connectors. For details on specific functionality limitations, see [Workflow Data Fabric - Primary Connectors Limitations \[KBB0010487\]](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KBB0010487).

The connector has been enhanced to improve the performance of the following Glide queries and list view operations. These improvements allow the majority of queries to be executed at the data source.

* Sort
* Limit
* Filter
* GroupBy
* avg()
* count()
* max()
* min()
* sum()
