features:
|
|
- |
|
|
Add new configuration option ``rbd_thin_provisioning`` and
|
|
``filesystem_thin_provisioning`` to rbd and filesystem
|
|
store to enable or not sparse upload, default are False.
|
|
|
|
A sparse file means that we do not actually write null byte sequences
|
|
but only the data itself at a given offset, the "holes" which can
|
|
appear will automatically be interpreted by the storage backend as
|
|
null bytes, and do not really consume your storage.
|
|
|
|
Enabling this feature will also speed up image upload and save
|
|
network traffic in addition to save space in the backend, as null
|
|
bytes sequences are not sent over the network.
