You need more than just a list of companies using it, you can create a similar list for just about any technology, good or bad.

Sony is a worldwide company with 127,000 employees, they alone probably use just about every database system around. So saying sony uses mongo isn't impressive, for all we know it was just a side project from an intern that has 100 documents, there is no context.

If we use your tortured logic that reference sites are meaningless then no technology in the history of the world is ever production ready.

Well I have worked for a number of billion dollar companies who have run MongoDB so there is first hand evidence.

Hell, I work at a Fortune 1000 company that uses Mongo. Thankfully I'm not on that team (we're mostly postgres with some mysql derivatives mixed in). Trust me, nobody here actually likes dealing with Mongo.

By your logic Visual Source Safe was production ready.

Well _maybe_ reference sites _are_ meaningless as measure of production readiness?

And how is that a paradigm shift? Non-relational, non-SQL databases have been around for a long, long time.

Your parent commenter doesn't like Mongo. So it's not production ready.

Eh I don't like Mongo because I've used it. IDK, it's been a few years since I've had to deal with mongo in a production environment. I don't miss it. I dislike that it's slow to get data to/from the javascript interpreter -- and that the solution was to work around it with the aggregation framework.

I don't like the unsafe defaults (data integrity, access control).

I don't like the magical, unreliable sharding that you have little to no control over.
