Limitations with Dataflows

‎06-23-2021 10:49 PM

I just have a general question. 

What are the limitations with dataflows regarding the size of tables? I have a dataflow with 3 tables each 200MM rows.

I use these tables within a report, but I filter them first to use just 50MM rows.

Where is the size of the dataflow stored? Is it even stored? I can't see the impact of the dataflow within the workspace storage.

With regards to the limitations please read this article: https://docs.microsoft.com/en-us/power-bi/transform-model/dataflows/dataflows-features-limitations

It is not possible to see the size of a dataflow unless you choose to store dataflow data in your own data lake (gen2) . There is an idea which you can vote for: https://ideas.powerbi.com/ideas/idea/?ideaid=5b955cf8-38ac-4864-ac3a-4993cad1b2d6
