Data stores

• [RemoteDataStore] (https://github.com/afeld/magickly/blob/master/lib/dragonfly/data_storage/remote_data_store.rb) - fetch images from remote urls (meaning the images are read-only - part of magickly)
• [JoyentMantaDataStore] (https://github.com/onyxrev/dragonfly-manta_data_store) - store and access objects in the Joyent Manta distributed cloud storage platform.
• MogileFSDataStore - Jamie Winsor ([email protected]) - retrieve and store in MogileFS, a distributed file store
• RelationalDataStore - Captain Mike ([email protected]) - store files in a relational database (such as SQLite or PostgreSQL)
• PostgresDataStore: uses PostgreSQL's native Large Object mechanism, so it's very (extremely!) fast and happily works with files > 1GB.
• The dragonfly-activerecord gem is a drop-in, database-backed store implementation, tested with Ruby 1.9 to 2.1, with SQLite, MySQL, or PostgreSQL.
• Dropbox data store - Dropbox-backed data store. Much easier to manage than S3.
