Recently I started learning mobile SDK and playing around with examples provided with SalesforceMobileSDK for iOS(using hybrid, so HTML + JS. No Objective-C!)
In AccountEditor app I noticed that I can create records offline, then go online and sync it. But the problem is that sync operation runs for each record which is slow(especially if I would have to upsert huge amounts of records).
So my question is:
Is it possible to upsert locally created records in bulk? And if so, how should I approach it?
