In-memory master data

I want to use Core Data as a cache for a larger set of data on a database server. Not all data will be in memory.

When we thought about this, 2 more questions came to mind:

  • Can an error (for example, for 1-n relations) be used with persistent storage in memory, and if so, how do you cheat the error?

  • The context of the main data-driven objects has a continuity interval. Does this also apply to storage in memory?

Or should I use NSAtomicStore for this purpose?
