You know, I do not think there is a true substitute for Mongo in regard to a general purpose NoSQL database to serve use cases that SQL databases cannot adequately handle (meaning, even if it can handle it, it still makes it painful to use an SQL to do so).
For niche applications, and for more mundane applications there are many alternatives. But there is no substitute for, as Mongo states, “modern general purpose database.”
Whether that makes Mongo a place to be investment wise now…maybe not, maybe so, but you can see the buy out value with Mongo. In my mind at the moment, given the current FUD surrounding Mongo, an AYX like reaction when TAbleau announced their “competing” data product towards mongo stock may become an opportunity. But Mongo is down around 20% over the last few days but I would not call it at a FUD related valuation yet.
My opinion anyways in regard to Mongo on the current news being digested.
