Not exactly. DocumentDB was primarily a document store. Cosmos allows you to store graphs and KV pairs as well.

I was unable to glean from a quick read of the consistency documentation, does CosmosDB support uniqueness and foreign key constraints?

Afraid not - there's no real concept of constraints with CosmosDB.

DocumentDB is KV.

DocumentDB looks like a JSON document store?

[hoschicz]

It is.
