Saving 10,000 records Core Data

Question

I work with the synchronization application. How do I "roughly" open the database (Core Data) to perform 10,000 operations (delete, save, etc.) and then close?

I understand that now works like this:

• opened database
• done action
• closed and so 10,000 times.

Correct if wrong, I will be only too happy

Answer 1

Just do your 10,000 operations and at the end save the managed object context. Just make sure to save at the end and not after each object. This will speed up the progress dramatically.
