Clicked on link expecting to see a tape based key-value datastore.

  It's being worked on. There's a lot of overhead inherent in random access, which really isn't necessary for most applications. ;)

    That sounds interesting. Is it web scale?
  • EGreg 16y ago
    yeah, you just insert your records in the only order you'd ever want to get them out

    Hm, tape drives aren't even sold anymore, otherwise I might try.
    • gwern 16y ago
      It may not be a bad idea to borrow old tape-drive ideas for modern technologies - I mean, hard drives are ever slower compared to cache or RAM, and they are faster at linear seeks (like tapes) than random-access. Hard drives are the new tape?

        Tapes are the new Hard Drive. http://en.wikipedia.org/wiki/Linear_Tape_File_System http://en.wikipedia.org/wiki/Linear_Tape_File_System A Random Access Filesystem that runs on LTO5. (And it even supports OSX!) Cool hack. Just don't ask me why they bothered.

      Sure they are -- tape libraries are still sold, primarily for backups, eg: http://www.quantum.com/Products/TapeLibraries/index.aspx http://www.quantum.com/Products/TapeLibraries/index.aspx http://www.dell.com/us/en/enterprise/storage/tapebackup_automation/cp.aspx?refid=tapebackup_automation&cs=555&s=biz http://www.dell.com/us/en/enterprise/storage/tapebackup_auto...

      If you ever get a chance to poke around a large corporate data center -- see if you can check out a SL8500 or one of the TS3500 units.. They're the big things with all kinds of flying robotic arms and crap-loads of storage. Just don't try and walk inside one while the robots are moving. For reference -- an LTO5 Tape holds about 3TB of data. (and has decent compression -- so that could go much higher)

  yeah, me too. a NoSQL replacement for tar.
