The following has me confused.

Should I not use fetch specs? In other words, while all my objects are looking good and all my relationships clean are
clean should I use fetch specs or should I just get all the objects through the relationship and then filter them programatically?


Or, is there a secret when creating relationships that will select a subset. My Portfolio object has a one to many
relationship to requests, however I just want to show only open requests as an example.


I of course want to take advantage of caching. Also, only after clicking on a request would I need to worry about updates.

BTW, no fetch spec result is cached. That will always go to the database. I'm not certain if
the resultant objects are cached or not. So I try to write things such that I only go through
relationships. Those are cached and offer amazing performance. But it's not always possible.
If the fetch is marked as refreshing refetched objects then the newly fetched rows will update the cache. Otherwise only the PK (and Entity, restricting value) is used to identify the snapshots already cached.
