Realm Syncing relationship between two collection


So just for my understanding.

E.g. I’m Amazon and want to create an App for an iPhone with a shopping basket. My customer is having a shopping basket with two articles.

I want to display that shopping basket in my App, also when the User is off line. So, I will need some information of the 2 articles in the shopping basket that are stored in my article database with one billion records (e.g. a product image or a description).

What you propose is to synchronize the one billion records to the User’s iPhone so we can then map the 2 articles?

No - I would probably denormalize some of the data in that case so you can display some information about the Item in the user’s cart.
