I’ve heard (way) more than one story about MongoDB mysteriously annihilating all the data. Launched into oblivion. The worst imaginable outcome for a database.

  Oh yeah, I have two of those myself.

  It's worth mentioning that MongoDB used to have a terrible storage engine--and it would do all sorts of stuff like this under stress. But it was replaced with a much better engine (WiredTiger) with write-ahead journaling and checkpoints around the year 2016.

    In 2020, MongoDB continues to fail consistency tests.

  I've worked at MongoDB for seven years right next to our EMEA/APAC support teams. We've never come across and instance where MongoDB was "mysteriously annihilating all the data". We would take any incidence of that whether it was a paying customer or not very seriously. If you know someone this has happened to I would encourage you to get them contact us.
