Power BI Premium Dataflows import large fact table

Hi All

We have Power BI Premium capacity, I wanted to create a dataflow to push a large fact table with 2 billion rows with incremental refresh along with its dimension tables. So multiple power BI developers can plug their report into Dataflows.

Is there any maximum no of rows cap in dataflows ? 

Also I Would like to know the best practices for  Dataflows and to handle Large datasets in Power BI Premium.

The issue I currently have is, The fact and dim table sites on the Synapse dedicated pool, but the performance is bad when we do direct query mode from Power BI Desktop, so we end up creating aggregated table at different granularity and some materialised views. 

To reducing these housekeeping works and since the end user requirement change over the period of time, I think of pushing the whole table into Power BI Premium - Dataflow service and turn on the Enhanced complute engine so the report developers can point it to this  dataflow (using direct query mode) .  Is this a best practice ?
