Honestly, it's weird that you never ran into this. This is a requirement for any data store and I've never not used atomic updates at any company. Most basic example: what if two users load the same object at the same time and you want to increment a "seen" count...?

I guess it was sufficient to not have that kind of accuracy in most of the application to deliver user value. There probably were parts of the application where we used transactions. Could be a cool feature to build for this, though.
