Echantillonnage

Par défaut, les traitements dans Power Query sont effectués sur un échantillon de données de 1000 lignes. De ce fait, le profilage des colonnes est en fonction des 1000 premières lignes du jeu de données.

Cependant, il est possible de lever cet échantillonnage en basant le profilage sur l'ensemble du jeu de données.
