How to handle data offline Sync with AWS AppSync?

Question

I have set up an IOS app with DataSource as "HTTP endpoint". I can fetch all users and auto store in mysqli DB and this data is available offline. I have also tried the subscriptions to mutations which also works fine.

Now my question is how do I sync the data. suppose I have 10 rows and there is 2 new row available when I was offline. how do I know these are available?
