And when you do have to jump off, you'll be screwed. Because the jump off is usually from in-memory Mnesia with guaranteed sub-millisecond responses to a proper database with at least a magnitude higher latency. And you realize that your app is completely dependent on sub-millisecond responses :)
Low latency is addictive. And by the time when you think you might need to change you’re probably become such a skilled engineer that you realize that everybody that shit on mnesia does not know what they talk about. :)
