About The Project

Distribyted tries to make easier integrations with other applications among torrent files, presenting them as a standard filesystem.

We aim to use some compressed file characteristics to avoid download it entirely, just the parts that we'll need.

Also, if the file format is not supported, distribyted can stream and seek through the file if needed.

Note that distribyted is in alpha version, it is a proof of concept with a lot of bugs.

Use Cases

• Play multimedia files on your favorite video or audio player. These files will be downloaded on demand and only the needed parts.
• Explore TBs of data from public datasets only downloading the parts you need. Use Jupyter Notebooks directly to process or analyze this data.
• Play your ROM backups directly from the torrent file. You can have virtually GBs in games and only downloaded the needed ones.

Supported Expandable File Formats

Distribyted can show some kind of files directly as folders, making it possible for applications read only the parts that they need. Here is a list of supported, to be supported and not supported formats.

Supported

• zip: Able to uncompress just one file. The file is decompressed to a temporal file sequentially to make possible seek over it. The decompression stops if no one is reading it.

To Be Supported

• tar: Seek to any file and inside that files using a modified standard library. Not useful on .tar.gz files.
• 7zip: Similar to Zip. Need for a library similar to zip.
• xz: Only worth it when the file is created using blocks. Possible library here and here.

Not Supported

• gzip: As far as I know, it doesn't support random access.

Getting Started

Get the latest release from releases page or download the source code and execute make build.

Run the program: ./distribyted-[VERSION]-[OS]-[ARCH]

Defaults are good enough for starters, but you can change them. Here is the output of ./distribyted -help:

NAME:
   distribyted - Torrent client with on-demand file downloading as a filesystem.

USAGE:
   distribyted [global options] [arguments...]

GLOBAL OPTIONS:
   --config value      YAML file containing distribyted configuration. (default: "./distribyted-data/config.yaml") [$DISTRIBYTED_CONFIG]
   --http-port value   HTTP port for web interface (default: 4444) [$DISTRIBYTED_HTTP_PORT]
   --fuse-allow-other  Allow other users to acces to all fuse mountpoints. You need to add user_allow_other flag to /etc/fuse.conf file. (default: false) [$DISTRIBYTED_FUSE_ALLOW_OTHER]
   --help, -h          show help (default: false)

Prerequisites on windows

Download and install WinFsp.

Usage

After executing and load all torrent or magnet files, a web interface will be available here: http://localhost:4444 It contains information about the mounted routes and torrent files like download/upload speed, leechers, seeders...

You can also modify the configuration file and reload the server from here: http://localhost:4444/config .

Docker

Docker run example:

docker run \
  --rm -p 4444:4444 \
  --cap-add SYS_ADMIN \
  --device /dev/fuse \
  --security-opt apparmor:unconfined \
  -v /tmp/mountpoints:/distribyted-data/mountpoints:shared \
  -v /tmp/metadata:/distribyted-data/metadata \
  -v /tmp/config:/distribyted-data/config \
  distribyted/distribyted:latest

Docker compose example:

distribyted:
    container_name: distribyted
    image: distribyted/distribyted:latest
    restart: always
    ports:
      - "4444:4444/tcp"
    volumes:
      - /home/user/mountpoints:/distribyted-data/mountpoints:shared
      - /home/user/metadata:/distribyted-data/metadata
      - /home/user/config:/distribyted-data/config
    security_opt:
      - apparmor:unconfined
    devices:
      - /dev/fuse
    cap_add:
      - SYS_ADMIN

Configuration File

root

Config key	Description
max-cache-size	Size in MB for the cache. This is the maximum space used by distribyted to store torrent data. Less used torrent data will be discarded if this value is reached.
metadata-folder-name	Folder where distribyted metadata will be stored.
mountPoints	List of folders where torrents will be mounted as a filesystem. Possible configuration keys described here.

mountpoints

Config key	Description
path	Path where a new fuse mount will be initialized. On Windows you can use a drive letter (X: per example) or a folder path that does not exist.
torrents	List of magnetUris or/and torrentPaths to be loaded on this fuse mount.
