Hi All,
I am new to PowerBI. Being a Excel user, I know that using lot of Formulas sometimes impacts the performance. Is it the same case with PowerBI? I looks for a similar topic, but could not find any response.
Are my calculated Columns, "calcuated" dynamically? Or stored within Cache as soon as its imported? I have about 1Million+ rows, and use calculated columns to get for example: Month(Date), Create YES/NO flags based of column's values and more.
Should I precalculate these values in my SQL server DB and then import them? Does creating new Calculated values within PowerBU have any mpact on perfromance?
Does using "Custom Column" in Query Editor make any difference? How different is it from Calc column?
Thanks,
Sam
