Support for schemas (full, mixed and none)
Support schema-full and schema-mixed modes like OrientDB. This way one can _design_ a graph with vertex and edge classes. This is extremely useful when modelling known domains and removes all burden to do this in code.
Cosmos DB is intended to be a schemaless database so we don’t support schemas in general. Support for this is not on our roadmap but will mark as unplanned and leave open for future consideration.
Thanks for your suggestion.

Support for schema definition (get all distinct property names and types in a collection)
schema may be useful for inference, see also rdfs
