Dataflow size limit
I've successfully broken my large model out into a number of Dataflows and they are all refreshing on their own schedules :-) I am facing a new challenge in that any Dataflow that is over about 300MB will refresh in Dataflows and display in Power BI Desktop Query Editor but fail to load when I apply the query in Power BI Desktop. The error is:
Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error] Received an unexpected EOF or 0 bytes from the transport stream..'.
When applying it will happily load the data to a point - normally to the full size as it pauses for a long time at the same value and then crashes with the error. I'm going to break the larger items out into smaller Dataflows and then combine them as a new Table in Power BI Desktop. That should reduce the sizes being transferred over the wire.

Yes. I've opened a ticket and I am awaiting a solution.
