On Td 14.0 , is it recommended to add Mvc on columns which we use for aggregations?
For example if our fact table which has 5-6 B rows , has a column QTY and the we use this column in sum() , would be better to leave it without MVC or not.
After some tests , the cpu decreased by 15% on join indexes cases and it remains almost the same or less
on direct agregations.
Any thoughts? Has anyone make similar tests?
