The problem is that Core Data doesn't use rows -- it doesn't have
any intrinsic ordering of objects (that's why unsorted results are
always sets, not arrays). There's no general concept of the "next"
10000 objects.
To query in chunks, you need to implement your own concept of
ordering (which may or may not be easy, depending on your
requirements).
Relationships are intrinsically unordered.
When fetching objects though, the order can be as deterministic as you
need it to be; set an appropriate sortDescriptor on the fetch request.
