I can’t really see key-store + SQL as “multi-model”
As far as I can a key-store/JSON/etc data base isn’t a “model” but just a value store that lets you roll-your-own data model, so the model is in code or “middleware” or somewhere else. Whether that’s a good idea or not, it’s not a data model. So mixing the different functionalities seems not “multi-model” but a general mess.
