Does Dataflow reduce the need to load data on source databases

We have an on premise SQL Datawarehouse, and the management of both this environment and Power BI fall to the same group. I feel like data load from our on premise server to Power BI would be more efficient if we used dataflows however I have not seen this particular usecase featured. Would a load of tables in to dataflow mean a fact table is loaded once from On Prem and then reused accross my datamodels? It is quite sluggish building in to Workflow, then refreshing, then connecting to a desktop report and I am wondering if this is a wasted effort. Feedback is appreciated. Thanks

Yes, the re-use of source data across datasets is one of the primary use cases for dataflows.

I hit a nother stumbling block, which is the requirement to have a shared model accross workspaces.  Any thoughts on that?

 

Yes, you can now share datasets and even promote them within an organization:

Share a dataset - Power BI | Microsoft Docs

 

Power BI datasets can now also be queried from other datasets, which opens even more possibilities.

Thanks- I am still not sold on the concept.
You load data to DataFlows, but still need to do a subsequent refresh of the datamodel. It might be quicker in Service than pulling from on Prem SQL database- but it still feels a way off what I want it to be - but I am quite demanding! 🙂
