Patrick from Realm here. Realm _can_ be used as a key-value store using our primary keys but at the moment it does expect a fixed schema (all of the keys can be optional though). It’d be trivial for us to relax that requirement and we do have dynamic APIs that allows this on Swift/Objective-C/Java. That said, there’s a lot more Realm can do that a K/V store can’t such as query efficiently on arbitrary properties, link objects in a graph, and more. Does that answer your question?

Yes -- is there a doc about the graph semantics?

You can add any object as a property of another object, and access them via dot notation: https://realm.io/docs/react-native/latest/#object-properties

You can probably find some more advanced examples in our Swift docs https://realm.io/docs/swift/latest/#relationships

We’re barely scratching the surface of this in our query language, which is heavily NSPredicate-inspired, but we might add more OpenCypher-ish features in the future. (And we’d greatly appreciate concrete use-cases or anything else you can share in a GitHub issue to help us prioritize development) https://github.com/realm/realm-js/issues

Sounds interesting!
