Weighted Average - Large Dataset

[Abishek]

Hi,
I am new to power BI. 

Is “Summarize Table” a good option for a large data set approx(60 million rows)?

Reason why I need this functionality is that I use "Weighted average" for all my Aggregation and Group By throughout all visuals,

“No default aggregation to be applied while using visuals ”.
All the visuals should use weighted average and have to change based on filter/slicers 

Can someone please help in choosing the right approach to solve this problem. Because this is a very important functionality.   ?

@Abishek , You formula should avoid row calculation. You should have measure like

Divide(Sum(Table[A]) , Sum(Table[B]))

or

Divide(Sum(Table[A]) , count(Table[A]))
