CloudTasksAsyncClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Union[str, google.cloud.tasks_v2beta2.services.cloud_tasks.transports.base.CloudTasksTransport] = 'grpc_asyncio', client_options: Optional[google.api_core.client_options.ClientOptions] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Cloud Tasks allows developers to manage the execution of background work in their applications.

Properties

transport

Returns the transport used by the client instance.

Returns

Type	Description
`CloudTasksTransport`	The transport used by the client instance.

Methods

CloudTasksAsyncClient

CloudTasksAsyncClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Union[str, google.cloud.tasks_v2beta2.services.cloud_tasks.transports.base.CloudTasksTransport] = 'grpc_asyncio', client_options: Optional[google.api_core.client_options.ClientOptions] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiates the cloud tasks client.

Parameters

Name	Description
`credentials`	`Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
`transport`	`Union[str, .CloudTasksTransport]` The transport to use. If set to None, a transport is chosen automatically.
`client_options`	`ClientOptions` Custom options for the client. It won't take effect if a `transport` instance is provided. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the `api_endpoint` property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.

Exceptions

Type	Description
`google.auth.exceptions.MutualTlsChannelError`	If mutual TLS transport creation failed for any reason.

acknowledge_task

Acknowledges a pull task.

The worker, that is, the entity that xref_leased this task must call this method to indicate that the work associated with the task has finished.

The worker must acknowledge a task within the xref_lease_duration or the lease will expire and the task will become available to be leased again. After the task is acknowledged, it will not be returned by a later xref_LeaseTasks, xref_GetTask, or xref_ListTasks.

Parameters

Name	Description
`request`	`Union[google.cloud.tasks_v2beta2.types.CreateQueueRequest, dict]` The request object. Request message for CreateQueue.
`parent`	`str` Required. The location name in which the queue will be created. For example: `projects/PROJECT_ID/locations/LOCATION_ID` The list of allowed locations can be obtained by calling Cloud Tasks' implementation of ListLocations. This corresponds to the `parent` field on the `request` instance; if `request` is provided, this should not be set.
`queue`	`Queue` Required. The queue to create. [Queue's name][google.cloud.tasks.v2beta2.Queue.name] cannot be the same as an existing queue. This corresponds to the `queue` field on the `request` instance; if `request` is provided, this should not be set.
`retry`	`google.api_core.retry.Retry` Designation of what errors, if any, should be retried.
`timeout`	`float` The timeout for this request.
`metadata`	`Sequence[Tuple[str, str]]` Strings which should be sent along with the request as metadata.

Returns

Type	Description
`google.cloud.tasks_v2beta2.types.Queue`	A queue is a container of related tasks. Queues are configured to manage how those tasks are dispatched. Configurable properties include rate limits, retry options, target types, and others.

create_task

create_task(request: Optional[Union[google.cloud.tasks_v2beta2.types.cloudtasks.CreateTaskRequest, dict]] = None, *, parent: Optional[str] = None, task: Optional[google.cloud.tasks_v2beta2.types.task.Task] = None, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

Creates a task and adds it to a queue.

Tasks cannot be updated after creation; there is no UpdateTask command.

For [App Engine queues][google.cloud.tasks.v2beta2.AppEngineHttpTarget], the maximum task size is 100KB.
For xref_pull queues, the maximum task size is 1MB.

from google.cloud import tasks_v2beta2

def sample_create_task():
    # Create a client
    client = tasks_v2beta2.CloudTasksClient()

    # Initialize request argument(s)
    request = tasks_v2beta2.CreateTaskRequest(
        parent="parent_value",
    )

    # Make the request
    response = client.create_task(request=request)

    # Handle the response
    print(response)

Parameters

Name	Description
`request`	`Union[google.cloud.tasks_v2beta2.types.CreateTaskRequest, dict]` The request object. Request message for CreateTask.
`parent`	`str` Required. The queue name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID` The queue must already exist. This corresponds to the `parent` field on the `request` instance; if `request` is provided, this should not be set.
`task`	`Task` Required. The task to add. Task names have the following format: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID`. The user can optionally specify a task name. If a name is not specified then the system will generate a random unique task id, which will be set in the task returned in the response. If schedule_time is not set or is in the past then Cloud Tasks will set it to the current time. Task De-duplication: Explicitly specifying a task ID enables task de-duplication. If a task's ID is identical to that of an existing task or a task that was deleted or completed recently then the call will fail with `ALREADY_EXISTS][google.rpc.Code.ALREADY_EXISTS]`. If the task's queue was created using Cloud Tasks, then another task with the same name can't be created for `1hour` after the original task was deleted or completed. If the task's queue was created using queue.yaml or queue.xml, then another task with the same name can't be created for `9days` after the original task was deleted or completed. Because there is an extra lookup cost to identify duplicate task names, these CreateTask calls have significantly increased latency. Using hashed strings for the task id or for the prefix of the task id is recommended. Choosing task ids that are sequential or have sequential prefixes, for example using a timestamp, causes an increase in latency and error rates in all task commands. The infrastructure relies on an approximately uniform distribution of task ids to store and serve tasks efficiently. This corresponds to the `task` field on the `request` instance; if `request` is provided, this should not be set.
`retry`	`google.api_core.retry.Retry` Designation of what errors, if any, should be retried.
`timeout`	`float` The timeout for this request.
`metadata`	`Sequence[Tuple[str, str]]` Strings which should be sent along with the request as metadata.

Returns

Type	Description
`google.cloud.tasks_v2beta2.types.Task`	A unit of scheduled work.

Type Description

google.iam.v1.policy_pb2.Policy Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources. A Policy is a collection of bindings. A binding binds one or more members to a single role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions (defined by IAM or configured by users). A binding can optionally specify a condition, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource. **JSON Example** { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": ["user:eve@example.com"], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01t00:00:00.000z')",="" }="" }="" ]="" }="" **yaml="" example**="" bindings:="" -="" members:="" -="" user:\="" mike@example.com="" -="" group:\="" admins@example.com="" -="" domain:google.com="" -="" serviceaccount:\="" my-project-id@appspot.gserviceaccount.com="" role:="" roles/resourcemanager.organizationadmin="" -="" members:="" -="" user:\="" eve@example.com="" role:="" roles/resourcemanager.organizationviewer="" condition:="" title:="" expirable="" access="" description:="" does="" not="" grant="" access="" after="" sep="" 2020="" expression:="" request.time="">< timestamp('2020-10-01t00:00:00.000z')="" for="" a="" description="" of="" iam="" and="" its="" features,="" see="" the="" [iam="" developer's="" guide](\="">

`lease_duration`	`google.protobuf.duration_pb2.Duration` Required. The duration of the lease. Each task returned in the response will have its schedule_time set to the current time plus the `lease_duration`. The task is leased until its schedule_time; thus, the task will not be returned to another LeaseTasks call before its schedule_time. After the worker has successfully finished the work associated with the task, the worker must call via AcknowledgeTask before the schedule_time. Otherwise the task will be returned to a later LeaseTasks call so that another worker can retry it. The maximum lease duration is 1 week. `lease_duration` will be truncated to the nearest second. This corresponds to the `lease_duration` field on the `request` instance; if `request` is provided, this should not be set.
`retry`	`google.api_core.retry.Retry` Designation of what errors, if any, should be retried.
`timeout`	`float` The timeout for this request.
`metadata`	`Sequence[Tuple[str, str]]` Strings which should be sent along with the request as metadata.

Forces a task to run now.

When this method is called, Cloud Tasks will dispatch the task, even if the task is already running, the queue has reached its xref_RateLimits or is xref_PAUSED.

This command is meant to be used for manual debugging. For example, xref_RunTask can be used to retry a failed task after a fix has been made or to manually force a task to be dispatched now.

The dispatched task is returned. That is, the task that is returned contains the xref_status after the task is dispatched but before the task is received by its target.

If Cloud Tasks receives a successful response from the task's target, then the task will be deleted; otherwise the task's xref_schedule_time will be reset to the time that xref_RunTask was called plus the retry delay specified in the queue's xref_RetryConfig.

xref_RunTask returns NOT_FOUND][google.rpc.Code.NOT_FOUND] when it is called on a task that has already succeeded or permanently failed.

xref_RunTask cannot be called on a [pull task][google.cloud.tasks.v2beta2.PullMessage].
