I'm testing different way of using JI but I'm still having some question.
Does anybody can explain why a SELECT with a COUNT(FIELD_1) or COUNT (DISTINCT FIELD_1) statement does not use the JI? I understand why we
can't create a JI with COUNT DISTINCT but I can't figure out for the SELECT statement. In my mind, the JI have the information to return the COUNT
information.
