%description
    SeaweedFS is a simple and highly scalable distributed file system.
    There are two objectives: to store billions of files and to serve
    the files fast! Instead of supporting full POSIX file system
    semantics, SeaweedFS choose to implement only a key/file mapping,
    but it provides a hierarchical filer frontend, too. SeaweedFS
    started by implementing Facebook's Haystack design paper. It grows
    with more features along the way. SeaweedFS knows about three
    server roles: "filter" (hierarchical tree storage frontend server),
    "master" (volume managing server) and "volume" (data storage
    server).
