Our customer has over 100K users and around 20 custom attributes in Active Directory that we will populate. We extended the ADSAccount table to include these attributes. We also needed to extend the schema of the personwantsorg and shoppingcartitem tables because they do not have enough custom properties to allow us to push all the attributes we need to Active Directory.
My question is what is the best practice around indexing new attributes added via the Schema Extension tool?
