>Can you point out an example of data you would store in a document database, which is not purely for caching purposes? I've been a pretty vocal critic of document databases in the past[1] (indeed, I get a little bit of a chuckle recalling the prevailing HN wisdom a couple of years ago and comparing it to now), however I recently had a project where added data was immutable and additive and non-relational: MongoDB was the perfect choice, and provided a zero friction, easy to deploy and scale solution.
