If I understand it correctly the cardinality only reflects the target table.
Does the cardinality have any influence at all - thus providing the wrong cardinality gives different results.
Or is this cardinality for documentaion purposes only since association is by default left outer join.
I see mixed messages about this matter.
Speaking of, what about the cardinality for the inner? I only see examples with [1:inner].
I see also examples with filters on inner without cardinality. A good explanation and/or documentation on all this would be very nice, since it's rather confusion with all these mixed/contradictional messages.
