Large object support

Object Storage (swift) uses segmentation to support the upload of large
|
|
|
|
|
objects. By default, Object Storage limits the download size of a single
|
|
|
|
|
object to 5GB. Using segmentation, uploading a single object is virtually
|
|
|
|
|
unlimited. The segmentation process works by fragmenting the object,
|
|
|
|
|
and automatically creating a file that sends the segments together as
|
|
|
|
|
a single object. This option offers greater upload speed with the possibility
|
|
|
|
|
of parallel uploads.

Large objects
|
|
|
|
|
~~~~~~~~~~~~~
|
|
|
|
|
The large object is comprised of two types of objects:
|
|
|
|
|
|
|
|
|
|
- **Segment objects** store the object content. You can divide your
|
|
|
|
|
content into segments, and upload each segment into its own segment
|
|
|
|
|
object. Segment objects do not have any special features. You create,
|
|
|
|
|
update, download, and delete segment objects just as you would normal
|
|
|
|
|
objects.
|
|
|
|
|
|
|
|
|
|
- A **manifest object** links the segment objects into one logical
|
|
|
|
|
large object. When you download a manifest object, Object Storage
|
|
|
|
|
concatenates and returns the contents of the segment objects in the
|
|
|
|
|
response body of the request. The manifest object types are:
|
|
|
|
|
|
|
|
|
|
- **Static large objects**
|
|
|
|
|
- **Dynamic large objects**
