It typically contains the ID of the target resource that the operation is performed on.
Any method that returns a long-running operation should document the metadata type, if any.

enum (Versioning)

Bucket versioning status.
For details, see documentation.

  • VERSIONING_UNSPECIFIED

  • VERSIONING_DISABLED: The bucket is unversioned, i.e. versioning has never been enabled for the bucket, including at its creation.
    Objects that are stored in the bucket have a version ID of null.

    To enable versioning, change status to VERSIONING_ENABLED via a BucketService.Update request. Note that this
    action is irreversible, and a bucket with versioning enabled can never return to VERSIONING_DISABLED state.

  • VERSIONING_ENABLED: Bucket versioning is enabled, i.e. all new objects are versioned and given a unique version ID, and objects that
    already existed at the time versioning was enabled will be versioned and given a unique version ID when modified
    by future requests.

    To suspend versioning, change status to VERSIONING_SUSPENDED via a BucketService.Update request. You cannot
    disable versioning altogether for a bucket that already had it enabled; objects that had version IDs will keep
    them.

  • VERSIONING_SUSPENDED: Bucket versioning is suspended, i.e. new objects are not versioned, but objects that already existed at the time
    versioning was suspended are still versioned and keep their version IDs.

    To resume versioning, change status to VERSIONING_ENABLED via a BucketService.Update request.

Expiration

Field

Description

date

string (date-time)

Specific date of object expiration.

The rule continues to apply even after the date has passed, i.e. any new objects created in the bucket expire
immediately.

Exactly one of date, days, and expiredObjectDeleteMarker fields can be specified.

String in RFC3339 text format. The range of possible values is from
0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z, i.e. from 0 to 9 digits for fractions of a second.

To work with values in this field, use the APIs described in the
Protocol Buffers reference.
In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).

days

string (int64)

Time period, in number of days from the creation or modification of the object, after which an object expires.

Exactly one of days, date, and expiredObjectDeleteMarker fields can be specified.

expiredObjectDeleteMarker

boolean

Indicates whether a delete marker of an object with no non-current versions (referred to as an expired object
delete marker) is removed at the object's expiration.

Exactly one of expiredObjectDeleteMarker, date, and days fields can be specified.

Transition

List of transition rules.

The transition of an object is described as follows.

For the unversioned bucket (Bucket.versioning is VERSIONING_DISABLED), the object is transitioned to the
specified storage class.

For the bucket with versioning enabled (Bucket.versioning is VERSIONING_ENABLED) or suspended
(VERSIONING_SUSPENDED), the current version of the object is transitioned to the specified storage class.

Field

Description

date

string (date-time)

Specific date of object transition.

The rule continues to apply even after the date has passed, i.e. any new objects created in the bucket are
transitioned immediately.

At most one of date and days fields can be specified.

String in RFC3339 text format. The range of possible values is from
0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z, i.e. from 0 to 9 digits for fractions of a second.

Protocol Buffers reference.
In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).

days

string (int64)

Time period, in number of days from the creation or modification of the object, after which an object is
transitioned.

At most one of days and date fields can be specified.

storageClass

string

Required field. Storage class to which an object is transitioned from standard storage.

The only supported class is cold storage (COLD, STANDARD_IA, NEARLINE all synonyms). Transitions from cold
to standard storage and transitions to or from ice storage are not allowed.

AfterDays

Field

Description

daysAfterExpiration

Time period, in number of days from the start of the multipart upload, after which the incomplete upload is
aborted.

NoncurrentExpiration

Field

Description

noncurrentDays

string (int64)

Time period, in number of days since the version of an object was classified as non-current, after which the
version expires.

NoncurrentTransition

List of transition rules for non-current versions of objects in a bucket with versioning enabled
(Bucket.versioning is VERSIONING_ENABLED) or suspended (VERSIONING_SUSPENDED).

At transition, the non-current version of the object is transitioned to the specified storage class.

Field

Description

noncurrentDays

string (int64)

Time period, in number of days since the version of an object was classified as non-current, after which the
version is transitioned.

storageClass

string

Required field. Storage class to which a non-current version of an object is transitioned from standard storage.

The only supported class is cold storage (COLD, STANDARD_IA, NEARLINE all synonyms). Transitions from cold
to standard storage and transitions to or from ice storage are not allowed.

NoncurrentDeleteMarkers

Field

Description

noncurrentDays

string (int64)

Time period, in number of days since the version of a delete marker was classified as non-current, after which
the delete marker expires.
