Dataflow vs Dataset refresh

Haven't found any documentation on how data refresh works with respect to a dataflow and then a dataset sourced from that dataflow.   So looking for feedback, based on what I've discovered:   Bo...

    >So I assume the dataflow is much like a data storage component on its own that manages the updating from the data source, wherever that may be

     

    That's correct, technically PBI's Dataflow uses Azure Data Lake Gen2 for storage.

     

    One use case I plan to use this dual refresh structure for, is to handle sources (e.g. static files) that don't need to be refreshed in Dataflows where they'll be imported but not under scheduled refresh. I've found PBI's scheduled refreshes to fail easily, so cutting down the service's scheduled refreshes to sources that actually need to be refreshed should lower incidents (e.g. web API timeouts, credential issues etc.).

    Hi,

     

    After internal checking, it seems that the next refresh time update (without browser refresh) was fixed and is should be available in the following updates.

     

    I will keep monitor it.

     

    Thanks,

I believe Dataflows now have DirectQuery capability in Premium, therefore you could simply avoid refreshing the dataset. 

 

Though given the performance and stability of dataflows, I would think a composite model would be a better approach to limit the amount of DirectQuery happening.
