BlobLeaseClient

Constructor

BlobLeaseClient(client: BlobClient | ContainerClient, lease_id: str | None = None)

Parameters

Name	Description
client Required	BlobClient or ContainerClient The client of the blob or container to lease.
lease_id	str A string representing the lease ID of an existing lease. This value does not need to be specified in order to acquire a new lease, or break one. default value: None

Variables

Name	Description
id	str The ID of the lease currently being maintained. This will be None if no lease has yet been acquired.
etag	str The ETag of the lease currently being maintained. This will be None if no lease has yet been acquired or modified.
last_modified	datetime The last modified timestamp of the lease currently being maintained. This will be None if no lease has yet been acquired or modified.

Methods

acquire	Requests a new lease. If the container does not have an active lease, the Blob service creates a lease on the container and returns a new lease ID.
break_lease	Break the lease, if the container or blob has an active lease. Once a lease is broken, it cannot be renewed. Any authorized request can break the lease; the request is not required to specify a matching lease ID. When a lease is broken, the lease break period is allowed to elapse, during which time no lease operation except break and release can be performed on the container or blob. When a lease is successfully broken, the response indicates the interval in seconds until a new lease can be acquired.
change	Change the lease ID of an active lease.
release	Release the lease. The lease may be released if the client lease id specified matches that associated with the container or blob. Releasing the lease allows another client to immediately acquire the lease for the container or blob as soon as the release is complete.
renew	Renews the lease. The lease can be renewed if the lease ID specified in the lease client matches that associated with the container or blob. Note that the lease may be renewed even if it has expired as long as the container or blob has not been leased again since the expiration of that lease. When you renew a lease, the lease duration clock resets.

acquire

Requests a new lease.

If the container does not have an active lease, the Blob service creates a lease on the container and returns a new lease ID.

acquire(lease_duration: int = -1, **kwargs: Any) -> None

Parameters

Name	Description
lease_duration Required	int Specifies the duration of the lease, in seconds, or negative one (-1) for a lease that never expires. A non-infinite lease can be between 15 and 60 seconds. A lease duration cannot be changed using renew or change. Default is -1 (infinite lease).

Keyword-Only Parameters

Name	Description
if_modified_since	datetime A DateTime value. Azure expects the date value passed in to be UTC. If timezone is included, any non-UTC datetimes will be converted to UTC. If a date is passed in without timezone info, it is assumed to be UTC. Specify this header to perform the operation only if the resource has been modified since the specified time.
if_unmodified_since	datetime A DateTime value. Azure expects the date value passed in to be UTC. If timezone is included, any non-UTC datetimes will be converted to UTC. If a date is passed in without timezone info, it is assumed to be UTC. Specify this header to perform the operation only if the resource has not been modified since the specified date/time.
etag	str An ETag value, or the wildcard character (*). Used to check if the resource has changed, and act according to the condition specified by the match_condition parameter.
match_condition	MatchConditions The match condition to use upon the etag.
if_tags_match_condition	str Specify a SQL where clause on blob tags to operate only on blob with a matching value. eg. "\"tagname\"='my tag'" New in version 12.4.0.
timeout	int Sets the server-side timeout for the operation in seconds. For more details see https://learn.microsoft.com/rest/api/storageservices/setting-timeouts-for-blob-service-operations. This value is not tracked or validated on the client. To configure client-side network timesouts see here.

Returns

Type	Description
None

break_lease

Break the lease, if the container or blob has an active lease.

Once a lease is broken, it cannot be renewed. Any authorized request can break the lease; the request is not required to specify a matching lease ID. When a lease is broken, the lease break period is allowed to elapse, during which time no lease operation except break and release can be performed on the container or blob. When a lease is successfully broken, the response indicates the interval in seconds until a new lease can be acquired.

break_lease(lease_break_period: int | None = None, **kwargs: Any) -> int

Parameters

Name

Description

lease_break_period Required

int This is the proposed duration of seconds that the lease should continue before it is broken, between 0 and 60 seconds. This break period is only used if it is shorter than the time remaining on the lease. If longer, the time remaining on the lease is used. A new lease will not be available before the break period has expired, but the lease may be held for longer than the break period. If this header does not appear with a break operation, a fixed-duration lease breaks after the remaining lease period elapses, and an infinite lease breaks immediately.
