NoSQL databases were the future. MongoDB was the database for ‘modern’ web engineers and used by countless startups. What happened?
I was on the Mongo hype-train for awhile and what happened was the rise of data as a resource and companies rediscovering that your databases aren’t just for storing data but that they are for discovering new things lurking there-in. Mongo, with it’s really piss-poor joining capabilities just doesn’t play well in that world. RDBMS do.
