Could you elaborate please on the untold pain part? We use Mongo as our primary storage at the moment and I would like to avoid painful issues. Thank you in advance. On the other note, I keep seeing people recommending Postgres, but to me that is apples vs. oranges. Just because it has json storage doesn't make it a replacement. How much effort and money a company needs to keep a replicated Postres cluster vs. Mongo? In one of my previous jobs we had to hire a consultant to do that. With Mongo pretty much any experience dev could do that. My personal view is that MongoDB's main advantage is its flexibility. It allows teams to shape and evolve the product as needed. When specific features/parts require new solutions, new solutions can be used (financial transactions, etc). Features that allowed us to leverage what we have instead of researching new tools were: 1. Schemaless - Logic is in the app; Gives visibility; Can be tested; Less migration headaches; Easier to evolve your architecture. 2. Indexed arrays, attributes (name, value pair) - Allows to be more creative (add tagging system to any type of data you have) 3. Aggregation - basic BI could be done from day one, which business can get value sooner. Of course, everyone's millage varies
