Why would anyone build with this?

REASON 1

Mount a Couchbase cluster as a local folder and browse its contents with any file manager.

REASON 2

Use grep or other command-line tools to search through database contents without an API.

REASON 3

Let a backup script read from the mounted directory as if pulling ordinary files off disk.

REASON 4

Study the code as a compact example of building a FUSE filesystem backed by a database.
