No.

The difference is that IDs are part of the public API.

Your database schema (KV or otherwise) is not.

[gary_0]

Generally the data model of the API resembles the data model of the DB schema. IDs that are generic numbers could be considered an aspect of a "flat" data model, where the application code assigns semantics to lists of data that are less strictly structured (and have less strict identifiers).

[paulddraper]

But what difference is there if you use KV stores or DBMS with strict schema? There is no consequence on your public interface.

That was the comment.
