Hi,
I have to operate on very long NSMutableArray (about ten milion of
objects). The list can not fit in our physical memory. I need to sort
the array, remove duplicates (data but not reference) and save the list
to hard drive.
The problem is that sort (sortUsingSelector) takes many hours and save
(encodeWithCoder, encodeObject) ran out of my patience after four days.
Do I need to sort it by myself or did I missed something? Can you
describe me how it saves a data? How to save the list?
Any ideas? Thanks for help
Berka
