Noooo, really?
It all depends on what you want to do. For things that are already in files like all that data that DeepSeek and other models train on and for which DS open sourced their own distributed file system, it makes sense to go with a distributed file system.
For OLTP you need a database with appropriate isolation levels.
I know someone will build a distributed file system on top of FoundationDB if they haven’t yet.
