(VI) Database files

    HAMMER uses 64 bit keys internally and makes key-based files directly
    available to userland.  Key-based files are not regular files and do not
    operate using a normal data offset space.

Interesting. What exactly are those database files used for? Is a database file attached to each file to store ACLs, for example? Or can it be used like btree(3)? Do they have their own namespace in the filesystem?


Wow! I a am really looking forward to try out HAMMER!!!

Michael
