Documentation

Overview

Package swift provides a storagedriver.StorageDriver implementation to store blobs in Openstack Swift object storage.

This package leverages the ncw/swift client library for interfacing with Swift.

It supports both TempAuth authentication and Keystone authentication (up to version 3).

Since Swift has no concept of directories (directories are an abstration), empty objects are created with the MIME type application/vnd.swift.directory.

As Swift has a limit on the size of a single uploaded object (by default this is 5GB), the driver makes use of the Swift Large Object Support (http://docs.openstack.org/developer/swift/overview_large_objects.html). Only one container is used for both manifests and data objects. Manifests are stored in the 'files' pseudo directory, data objects are stored under 'segments'.
