Huge many-to-many relationship

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?
