bulk inserts with SQLite and CoreData
You can specify the pragmas when adding your store to the store coordinator:
NSMutableDictionary *pragmaOptions = [NSMutableDictionary dictionary];[pragmaOptions setObject:@"OFF" forKey:@"synchronous"];[pragmaOptions setObject:@"OFF" forKey:@"count_changes"];[pragmaOptions setObject:@"MEMORY" forKey:@"journal_mode"];[pragmaOptions setObject:@"MEMORY" forKey:@"temp_store"];NSDictionary *storeOptions = [NSDictionary dictionaryWithObject:pragmaOptions forKey:NSSQLitePragmasOption];NSPersistentStore *store;NSError *error = nil;store = [psc addPersistentStoreWithType:NSSQLiteStoreType configuration: nil URL:url options:storeOptions error:&error];(Adapted from Persistent Store Features)
I strongly suggest to also read "Efficiently Importing Data".
