Text joins performance impact



We are building a huge calculation view which in the end will have ~1000 fields. This calculation view will be built from several smaller calculation views with union between them. Each small calculation view uses Analytical view that in the logical join uses attribute view with text join.

One of my big concerns is where should we add the text fields to this view? It will expand the number of fields in 30%.Maybe we should have these smaller joins in the BO IDT level.. When I try to check the performance in the viso plan (in smaller model..) I can see that the text joins are only performed when we ask for text. What do you think? Will calculation view with ~1000 fields will work? Will it make any diferent if we add the texts to our model?

Should we add the text joins in the analytical view Data Foundation or Logical join?
