Dimensions
Hello
I am seeing the possibility of generating a dimesion in my model with the combination of several fields, the dimesion would keep me with approximately 2 million rows.
Is this possible, is it optimal?
Would it be better to have different dimensions separately?
Having a single dimension I gain that as I will have a panel with several filters, as the user filters only information that hangs from the filter that has been made.
Thanks a lot
A greeting
