public class SetBucketVersioningRequest extends GenericRequest
Contains options for setting the versioning configuration for a bucket.
A bucket's versioning configuration can be in one of three possible states:
BucketVersioningConfiguration.OFF
BucketVersioningConfiguration.ENABLED
BucketVersioningConfiguration.SUSPENDED
By default, new buckets are created in the
BucketVersioningConfiguration.OFF
state. Once versioning is
enabled for a bucket, its status can never be reverted to
off
.
Objects created before versioning is enabled or while versioning is suspended
will be given the default null
version ID (see
OSSConstants.NULL_VERSION_ID
). Note that the
null
version ID is a valid version ID and is not the same
as having no version ID.
The versioning configuration of a bucket has different implications for each
operation performed on that bucket or for objects within that bucket. When
versioning is enabled, a PutObject
operation creates a unique
object version ID for the object being uploaded. The PutObject
operation
guarantees that if versioning is enabled for a bucket at the time of the request, the
new object can only be permanently deleted by calling the DeleteVersion
operation
and can never be overwritten.
Additionally, the PutObject
operation guarantees that if
versioning is enabled for a bucket at the time of the request, no other object will be
overwritten by that request. Refer to the documentation sections for individual APIs
for information on how versioning status affects the semantics of that
particular API.
OSS is eventually consistent. It may take time for the versioning status of a bucket to be propagated throughout the system.
