1. This is nothing to do with distributed storage

2. Symlinks are not required to be linked to existing file

3. Symlinks are not atomic

4. You still need to maintain filedb (or how do you resolve which storage contains given file?)

1. Depends on your distributed storage. If you use clustered file system your argument is void.

2. While true I fail to see how that is relevant. What part of my described flow would be broken?

3. While true I again fail to see relevance. Are you just listing characteristics of symlinks? A field in a database could exist with a filepath pointing to a non-existing file as well.

4. Sure. I was describing how to avoid the counter and magic number, not the database.
