before you want to use it in your project, make sure to have a look at the code - their codebase is pretty much comment free, very little number of tests. Other than the marketing term "posix file system", there is not any proof on such claim.

I am also not sure how it is a "distributed" file system given its storage is entirely done by S3. Should I call my backup program that backups my data to S3 every night a "distributed system"? When running on top of Redis, it explicitly mentions that Redis cluster is not supported. I haven't used Redis for many years, did I miss something here? A "distributed" file system built on top of a single instance of Redis? Sounds not very "distributed" to me.
