I think I know the answer, but I don't like the answer, so I am going
to ask it anyway, in case there is some way for me to get a different
answer than the one I don't like! ;-)
OK, I have a huge many-to-many relationship with a Join
ERXGenericRecord with the usual flatten relationships and not really
considered in my logic (except for some count methods)
List <--A-->> JoinListRecipient <<--B--> Recipient
The B side of the join is usually very small, no more than 100 in that
relationship.
The A side of the join is under 500 for 98% of List EOs, however the
others can be up to 1 or 2 million.
Do I really have to write my EO logic to actively maintain
JoinListRecipient EOs and get rid of the flattened relationships as
shown here?
List <--A-- JoinListRecipient <<--B--> Recipient
.... or is there some other answer that I might like?
