MongoDB is an interesting database for sure. It seems that they made a deliberate product decision to optimize developer experience and ease of use over things like consistency and database joins. Frankly, I think it's working pretty well for their business. I don't think there's anything that should immediately preclude the use of MongoDB in a production environment. I personally wouldn't use older versions of it as a single source of truth, but there are definitely some great use cases for it, such as allowing developers who only know JavaScript to write non-critical backend services. People seem to forget that database consistency is not binary, but residing on a spectrum. Like any other trade-offs, you should carefully measure the costs and benefits for your particular situation before making a decision.
