How soon will we be able to do something useful with Datasource names, through some combination of Power BI Desktop, the Power BI service and the Power BI REST API.
For example, both the Datasets.GetDatasourcesInGroup() and Datasets.GetGatewayDatasources() methods return lists of objects that have a name property, however this is invariably null or empty.
If I have a report with multiple datasources of the same type, it is difficult to determine which datasource is which when retargeting a dataset for a new environment, customer, tenant, etc. I would currently be forced to build a mapping based on the names of servers and databases (which are frequently opaquely named), whereas if Power BI Desktop allowed me to assign a name to a datasource then I could pick something more intelligible!
