one sided many-to-many?


  • Subject: one sided many-to-many?

Implementing a "one sided" one-to-many is straightforward (to prevent pulling in a million rows just to add a few entities to the both sides of relationship), but is there some special consideration when implementing a one-sided "many-to-many" since the join table has rows added and deleted for relationship adds and deletes rather than just setting and nullifying foreign keys in a regular one-to-many?

On a related note, does the fact that the VeoGen requires us to have a custom java subclass for join entities have any performance impact on huge many-to-many relationships ... or is that irrelevant?
