Can you tell me, the scenarios you used MongoDB for? Because I'm still curious about why would anyone use MongoDB after all these years.

It is the main database for a huge Rails app. They adopted Mongo right when its popularity started to decline. I always thought it was a very poor choice since the day I joined.

It is a especially bad choice considering that a lot of the data stored in it is IoT-like and the system creates a single document per event :facepalm:

I'm sorry to hear about your bad experience. From your comment I take it that you weren't using a time-series collection to store data in mdb which uses industry-standard compression techniques?

Because MongoDB is webscale.
