Class CloudTasksClient (2.8.1)

CloudTasksClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.tasks_v2beta2.services.cloud_tasks.transports.base.CloudTasksTransport]] = None, 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
TypeDescription
CloudTasksTransportThe transport used by the client instance.

Methods

CloudTasksClient

CloudTasksClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.tasks_v2beta2.services.cloud_tasks.transports.base.CloudTasksTransport]] = None, 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
NameDescription
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 google.api_core.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.

client_info google.api_core.gapic_v1.client_info.ClientInfo

The client info used to send a user-agent string along with API requests. If None, then default info will be used. Generally, you only need to set this if you're developing your own client library.

Exceptions
TypeDescription
google.auth.exceptions.MutualTLSChannelErrorIf mutual TLS transport creation failed for any reason.

__exit__

__exit__(type, value, traceback)

Releases underlying transport's resources.

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
NameDescription
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 google.cloud.tasks_v2beta2.types.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
TypeDescription
google.cloud.tasks_v2beta2.types.QueueA 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
NameDescription
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 google.cloud.tasks_v2beta2.types.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
TypeDescription
google.cloud.tasks_v2beta2.types.TaskA unit of scheduled work.

Deletes a queue.

This command will delete the queue even if it has tasks in it.

Note: If you delete a queue, a queue with the same name can't be created for 7 days.

WARNING: Using this method may have unintended side effects if you are using an App Engine queue.yaml or queue.xml file to manage your queues. Read Overview of Queue Management and queue.yaml <https://cloud.google.com/tasks/docs/queue-yaml>__ before using this method.

Leases tasks from a pull queue for xref_lease_duration.

This method is invoked by the worker to obtain a lease. The worker must acknowledge the task via xref_AcknowledgeTask after they have performed the work associated with the task.

The xref_payload is intended to store data that the worker needs to perform the work associated with the task. To return the payloads in the xref_response, set xref_response_view to xref_FULL.

A maximum of 10 qps of xref_LeaseTasks requests are allowed per queue. RESOURCE_EXHAUSTED][google.rpc.Code.RESOURCE_EXHAUSTED] is returned when this limit is exceeded. RESOURCE_EXHAUSTED][google.rpc.Code.RESOURCE_EXHAUSTED] is also returned when xref_max_tasks_dispatched_per_second is exceeded.

Parameters
NameDescription
request Union[google.cloud.tasks_v2beta2.types.LeaseTasksRequest, dict]

The request object. Request message for leasing tasks using LeaseTasks.

parent str

Required. The queue name. For example: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID This corresponds to the parent field on the request instance; if request is provided, this should not be set.

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.

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].

TypeDescription
google.iam.v1.policy_pb2.PolicyDefines 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](\="">
