Methods

CloudTasksClient

CloudTasksClient(
    transport=None,
    channel=None,
    credentials=None,
    client_config=None,
    client_info=None,
    client_options=None,
)

Constructor.

Parameters

Name	Description
`channel`	`grpc.Channel` DEPRECATED. A `Channel` instance through which to make calls. This argument is mutually exclusive with `credentials`; providing both will raise an exception.
`credentials`	`google.auth.credentials.Credentials` The authorization credentials to attach to requests. These credentials identify this application to the service. If none are specified, the client will attempt to ascertain the credentials from the environment. This argument is mutually exclusive with providing a transport instance to `transport`; doing so will raise an exception.
`client_config`	`dict` DEPRECATED. A dictionary of call options for each method. If not specified, the default configuration is 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.
`client_options`	`Union[dict, google.api_core.client_options.ClientOptions]` Client options used to set user options on the client. API Endpoint should be set through client_options.

create_queue

create_queue(parent, queue, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

Creates a queue.

Queues created with this method allow tasks to live for a maximum of 31 days. After a task is 31 days old, the task will be deleted regardless of whether it was dispatched or not.

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.

.. rubric:: Example

from google.cloud import tasks_v2beta3

client = tasks_v2beta3.CloudTasksClient()

parent = client.location_path('[PROJECT]', '[LOCATION]')

Initialize queue:

queue = { ... # The fully qualified path to the queue ... 'name': client.queue_path('[PROJECT]', '[LOCATION]', '[NAME]'), ... 'app_engine_http_queue': { ... 'app_engine_routing_override': { ... # The App Engine service that will receive the tasks. ... 'service': 'default', ... }, ... }, ... }

response = client.create_queue(parent, queue)

Parameters

Name	Description
`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`.
`queue`	`Union[dict, Queue]` Required. The queue to create. `Queue's name` cannot be the same as an existing queue. If a dict is provided, it must be of the same form as the protobuf message Queue
`retry`	`Optional[google.api_core.retry.Retry]` A retry object used to retry client library requests. If `None` is specified, requests will be retried using a default configuration.
`timeout`	`Optional[float]` The amount of time, in seconds, to wait for the client library request to complete. Note that if `retry` is specified, the timeout applies to each individual attempt.
`metadata`	`Optional[Sequence[Tuple[str, str]]]` Additional metadata that is provided to the client library method.

Exceptions

Type	Description
`google.api_core.exceptions.GoogleAPICallError`	If the request failed for any reason.
`google.api_core.exceptions.RetryError`	If the request failed due to a retryable error and retry attempts failed.
`ValueError`	If the parameters are invalid.

create_task

create_task(parent, task, response_view=None, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

Creates a task and adds it to a queue.

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

The maximum task size is 100KB.

.. rubric:: Example

from google.cloud import tasks_v2beta3

client = tasks_v2beta3.CloudTasksClient()

parent = client.queue_path('[PROJECT]', '[LOCATION]', '[QUEUE]')

TODO: Initialize task:

task = {}

response = client.create_task(parent, task)

Parameters

Name	Description
`parent`	`str` Required. The queue name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID` The queue must already exist.
`task`	`Union[dict, 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 executed recently then the call will fail with `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 executed. 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 executed. 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. If a dict is provided, it must be of the same form as the protobuf message Task
`response_view`	`View` The response_view specifies which subset of the `Task` will be returned. By default response_view is `BASIC`; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for `FULL` requires `cloudtasks.tasks.fullView` `Google IAM https://cloud.google.com/iam/`_ permission on the `Task` resource.
`retry`	`Optional[google.api_core.retry.Retry]` A retry object used to retry client library requests. If `None` is specified, requests will be retried using a default configuration.
`timeout`	`Optional[float]` The amount of time, in seconds, to wait for the client library request to complete. Note that if `retry` is specified, the timeout applies to each individual attempt.
`metadata`	`Optional[Sequence[Tuple[str, str]]]` Additional metadata that is provided to the client library method.

Exceptions

Type	Description
`google.api_core.exceptions.GoogleAPICallError`	If the request failed for any reason.
`google.api_core.exceptions.RetryError`	If the request failed due to a retryable error and retry attempts failed.
`ValueError`	If the parameters are invalid.

delete_queue

delete_queue(name, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

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.

This method resumes a queue after it has been PAUSED or DISABLED. The state of a queue is stored in the queue's state; after calling this method it will be set to RUNNING.

WARNING: Resuming many high-QPS queues at the same time can lead to target overloading. If you are resuming high-QPS queues, follow the 500/50/5 pattern described in Managing Cloud Tasks Scaling Risks <https://cloud.google.com/tasks/docs/manage-cloud-task-scaling>__.

.. rubric:: Example

from google.cloud import tasks_v2beta3

client = tasks_v2beta3.CloudTasksClient()

name = client.queue_path('[PROJECT]', '[LOCATION]', '[QUEUE]')

response = client.resume_queue(name)

Parameters

run_task

run_task(name, response_view=None, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

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 RateLimits or is PAUSED.

This command is meant to be used for manual debugging. For example, 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 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 schedule_time will be reset to the time that RunTask was called plus the retry delay specified in the queue's RetryConfig.

RunTask returns NOT_FOUND when it is called on a task that has already succeeded or permanently failed.

.. rubric:: Example

test_iam_permissions(resource, permissions, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

Returns permissions that a caller has on a Queue. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.

Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

.. rubric:: Example

from google.cloud import tasks_v2beta3

client = tasks_v2beta3.CloudTasksClient()

resource = client.queue_path('[PROJECT]', '[LOCATION]', '[QUEUE]')

TODO: Initialize permissions:

permissions = []

response = client.test_iam_permissions(resource, permissions)

Parameters

Name	Description
`resource`	`str` REQUIRED: The resource for which the policy detail is being requested. See the operation documentation for the appropriate value for this field.
`permissions`	`list[str]` The set of permissions to check for the `resource`. Permissions with wildcards (such as '' or 'storage.') are not allowed. For more information see `IAM Overview https://cloud.google.com/iam/docs/overview#permissions`__.
`retry`	`Optional[google.api_core.retry.Retry]` A retry object used to retry client library requests. If `None` is specified, requests will be retried using a default configuration.
`timeout`	`Optional[float]` The amount of time, in seconds, to wait for the client library request to complete. Note that if `retry` is specified, the timeout applies to each individual attempt.
`metadata`	`Optional[Sequence[Tuple[str, str]]]` Additional metadata that is provided to the client library method.

Exceptions

Type	Description
`google.api_core.exceptions.GoogleAPICallError`	If the request failed for any reason.
`google.api_core.exceptions.RetryError`	If the request failed due to a retryable error and retry attempts failed.
`ValueError`	If the parameters are invalid.

update_queue

update_queue(queue, update_mask=None, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

Updates a queue.

This method creates the queue if it does not exist and updates the queue if it does exist.

Queues created with this method allow tasks to live for a maximum of 31 days. After a task is 31 days old, the task will be deleted regardless of whether it was dispatched or not.

.. rubric:: Example

from google.cloud import tasks_v2beta3

client = tasks_v2beta3.CloudTasksClient()

Initialize queue:

queue = { ... # The fully qualified path to the queue ... 'name': client.queue_path('[PROJECT]', '[LOCATION]', '[NAME]'), ... 'app_engine_http_queue': { ... 'app_engine_routing_override': { ... # The App Engine service that will receive the tasks. ... 'service': 'default', ... }, ... }, ... }

response = client.update_queue(queue)

Parameters

Name	Description
`queue`	`Union[dict, Queue]` Required. The queue to create or update. The queue's `name` must be specified. Output only fields cannot be modified using UpdateQueue. Any value specified for an output only field will be ignored. The queue's `name` cannot be changed. If a dict is provided, it must be of the same form as the protobuf message Queue
`update_mask`	`Union[dict, FieldMask]` A mask used to specify which fields of the queue are being updated. If empty, then all fields will be updated. If a dict is provided, it must be of the same form as the protobuf message FieldMask
`retry`	`Optional[google.api_core.retry.Retry]` A retry object used to retry client library requests. If `None` is specified, requests will be retried using a default configuration.
`timeout`	`Optional[float]` The amount of time, in seconds, to wait for the client library request to complete. Note that if `retry` is specified, the timeout applies to each individual attempt.
`metadata`	`Optional[Sequence[Tuple[str, str]]]` Additional metadata that is provided to the client library method.

Exceptions

Type	Description
`google.api_core.exceptions.GoogleAPICallError`	If the request failed for any reason.
`google.api_core.exceptions.RetryError`	If the request failed due to a retryable error and retry attempts failed.
`ValueError`	If the parameters are invalid.
