Data Type

string

Default Value

""

Remarks

Leave this field blank if you authenticate to storage with a different method such as a storage access key or Azure AD credentials.

To create a suitable token in the Azure portal:

1. Open the target blob container and choose Shared access signature under Settings.
2. Select at least Create, Write, and Delete in Permissions, then set an appropriate start and expiry time.
3. Click Generate SAS token and URL and copy the value from Blob SAS token.

The token must stay valid and carry the selected permissions until every bulk-load job completes. Otherwise uploads will fail with permission or expiry errors.
