Apple

In my app I frequently need to run operations that read in nearly all the data in my database. One I run in the foreground (I have concurrent request handling on), and another I run in the background with its own EOObjectStoreCoordinator. If I understand how things work (and there's no guarantee of that), that would mean I basically have 4 copies of my database in memory at once (2 ECs and to object stores). As I use the data in a serial fashion, I was wondering if there's a way to release the EOs that are held in memory in both the EC and the Object Store once I know my each process is through with them, especially for the threaded process that has its own object store? Is just using ec.reset() at key points the way to go for the ec's? What about for the object stores?
