Types for Google Cloud Tasks v2beta3 API

class google.cloud.tasks_v2beta3.types.AppEngineHttpQueue(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

App Engine HTTP queue.

The task will be delivered to the App Engine application hostname specified by its [AppEngineHttpQueue][google.cloud.tasks.v2beta3.AppEngineHttpQueue] and [AppEngineHttpRequest][google.cloud.tasks.v2beta3.AppEngineHttpRequest]. The documentation for [AppEngineHttpRequest][google.cloud.tasks.v2beta3.AppEngineHttpRequest] explains how the task’s host URL is constructed.

Using [AppEngineHttpQueue][google.cloud.tasks.v2beta3.AppEngineHttpQueue] requires `appengine.applications.get <https://cloud.google.com/appengine/docs/admin-api/access-control>`__ Google IAM permission for the project and the following scope:

https://www.googleapis.com/auth/cloud-platform

app_engine_routing_override

Overrides for the [task-level app_engine_routing][google.cloud.tasks.v2beta3.AppEngineHttpRequest.app_engine_routing].

If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the [task-level app_engine_routing][google.cloud.tasks.v2beta3.AppEngineHttpRequest.app_engine_routing].

Type

google.cloud.tasks_v2beta3.types.AppEngineRouting

class google.cloud.tasks_v2beta3.types.AppEngineHttpRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

App Engine HTTP request.

The message defines the HTTP request that is sent to an App Engine app when the task is dispatched.

Using [AppEngineHttpRequest][google.cloud.tasks.v2beta3.AppEngineHttpRequest] requires `appengine.applications.get <https://cloud.google.com/appengine/docs/admin-api/access-control>`__ Google IAM permission for the project and the following scope:

https://www.googleapis.com/auth/cloud-platform

The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see How Requests are Routed and how routing is affected by dispatch files. Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol.

The [AppEngineRouting][google.cloud.tasks.v2beta3.AppEngineRouting] used to construct the URL that the task is delivered to can be set at the queue-level or task-level:

• If set, [app_engine_routing_override][google.cloud.tasks.v2beta3.AppEngineHttpQueue.app_engine_routing_override] is used for all tasks in the queue, no matter what the setting is for the [task-level app_engine_routing][google.cloud.tasks.v2beta3.AppEngineHttpRequest.app_engine_routing].

The url that the task will be sent to is:

• url = [host][google.cloud.tasks.v2beta3.AppEngineRouting.host] + [relative_uri][google.cloud.tasks.v2beta3.AppEngineHttpRequest.relative_uri]

Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with `login: admin <https://cloud.google.com/appengine/docs/standard/python/config/appref>`__. Because tasks are not run as any user, they cannot be dispatched to URIs restricted with `login: required <https://cloud.google.com/appengine/docs/standard/python/config/appref>`__ Task dispatches also do not follow redirects.

The task attempt has succeeded if the app’s request handler returns an HTTP response code in the range [200 - 299]. The task attempt has failed if the app’s handler returns a non-2xx response code or Cloud Tasks does not receive response before the [deadline][google.cloud.tasks.v2beta3.Task.dispatch_deadline]. Failed tasks will be retried according to the [retry configuration][google.cloud.tasks.v2beta3.Queue.retry_config]. 503 (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks’ traffic congestion control to temporarily throttle the queue’s dispatches. Unlike other types of task targets, a 429 (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue.

http_method

The HTTP method to use for the request. The default is POST.

The app’s request handler for the task’s target URL must be able to handle HTTP requests with this http_method, otherwise the task attempt fails with error code 405 (Method Not Allowed). See Writing a push task request handler and the App Engine documentation for your runtime on How Requests are Handled.

Type

google.cloud.tasks_v2beta3.types.HttpMethod

app_engine_routing

Task-level setting for App Engine routing.

If set, [app_engine_routing_override][google.cloud.tasks.v2beta3.AppEngineHttpQueue.app_engine_routing_override] is used for all tasks in the queue, no matter what the setting is for the [task-level app_engine_routing][google.cloud.tasks.v2beta3.AppEngineHttpRequest.app_engine_routing].

Type

google.cloud.tasks_v2beta3.types.AppEngineRouting

relative_uri

The relative URI.

The relative URI must begin with “/” and must be a valid HTTP relative URI. It can contain a path and query string arguments. If the relative URI is empty, then the root path “/” will be used. No spaces are allowed, and the maximum length allowed is 2083 characters.

Type

str

headers

HTTP request headers.

This map contains the header field names and values. Headers can be set when the [task is created][google.cloud.tasks.v2beta3.CloudTasks.CreateTask]. Repeated headers are not supported but a header value can contain commas.

Cloud Tasks sets some headers to default values:

• User-Agent: By default, this header is "AppEngine-Google; (+http://code.google.com/appengine)". This header can be modified, but Cloud Tasks will append "AppEngine-Google; (+http://code.google.com/appengine)" to the modified User-Agent.

If the task has a [body][google.cloud.tasks.v2beta3.AppEngineHttpRequest.body], Cloud Tasks sets the following headers:

• Content-Type: By default, the Content-Type header is set to "application/octet-stream". The default can be overridden by explicitly setting Content-Type to a particular media type when the [task is created][google.cloud.tasks.v2beta3.CloudTasks.CreateTask]. For example, Content-Type can be set to "application/json".

• Content-Length: This is computed by Cloud Tasks. This value is output only. It cannot be changed.

The headers below cannot be set or overridden:

• Host

• X-Google-*

• X-AppEngine-*

In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see request headers. These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response.

Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the [Task][google.cloud.tasks.v2beta3.Task]. For more information, see the [CreateTask][google.cloud.tasks.v2beta3.CloudTasks.CreateTask] documentation.

Type

MutableMapping[str, str]

body

HTTP request body.

A request body is allowed only if the HTTP method is POST or PUT. It is an error to set a body on a task with an incompatible [HttpMethod][google.cloud.tasks.v2beta3.HttpMethod].

Type

bytes

class HeadersEntry(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

class google.cloud.tasks_v2beta3.types.AppEngineRouting(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

App Engine Routing.

Defines routing characteristics specific to App Engine - service, version, and instance.

For more information about services, versions, and instances see An Overview of App Engine, Microservices Architecture on Google App Engine, App Engine Standard request routing, and App Engine Flex request routing.

service

App service.

By default, the task is sent to the service which is the default service when the task is attempted.

For some queues or tasks which were created using the App Engine Task Queue API, [host][google.cloud.tasks.v2beta3.AppEngineRouting.host] is not parsable into [service][google.cloud.tasks.v2beta3.AppEngineRouting.service], [version][google.cloud.tasks.v2beta3.AppEngineRouting.version], and [instance][google.cloud.tasks.v2beta3.AppEngineRouting.instance]. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If [host][google.cloud.tasks.v2beta3.AppEngineRouting.host] is not parsable, then [service][google.cloud.tasks.v2beta3.AppEngineRouting.service], [version][google.cloud.tasks.v2beta3.AppEngineRouting.version], and [instance][google.cloud.tasks.v2beta3.AppEngineRouting.instance] are the empty string.

Type

str

version

App version.

By default, the task is sent to the version which is the default version when the task is attempted.

For some queues or tasks which were created using the App Engine Task Queue API, [host][google.cloud.tasks.v2beta3.AppEngineRouting.host] is not parsable into [service][google.cloud.tasks.v2beta3.AppEngineRouting.service], [version][google.cloud.tasks.v2beta3.AppEngineRouting.version], and [instance][google.cloud.tasks.v2beta3.AppEngineRouting.instance]. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If [host][google.cloud.tasks.v2beta3.AppEngineRouting.host] is not parsable, then [service][google.cloud.tasks.v2beta3.AppEngineRouting.service], [version][google.cloud.tasks.v2beta3.AppEngineRouting.version], and [instance][google.cloud.tasks.v2beta3.AppEngineRouting.instance] are the empty string.

Type

str

instance

App instance.

By default, the task is sent to an instance which is available when the task is attempted.

Requests can only be sent to a specific instance if manual scaling is used in App Engine Standard. App Engine Flex does not support instances. For more information, see App Engine Standard request routing and App Engine Flex request routing.

Type

str

host

Output only. The host that the task is sent to.

The host is constructed from the domain name of the app associated with the queue’s project ID (for example .appspot.com), and the [service][google.cloud.tasks.v2beta3.AppEngineRouting.service], [version][google.cloud.tasks.v2beta3.AppEngineRouting.version], and [instance][google.cloud.tasks.v2beta3.AppEngineRouting.instance]. Tasks which were created using the App Engine SDK might have a custom domain name.

For more information, see How Requests are Routed.

Type

str

class google.cloud.tasks_v2beta3.types.Attempt(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

schedule_time

Output only. The time that this attempt was scheduled.

schedule_time will be truncated to the nearest microsecond.

Type

google.protobuf.timestamp_pb2.Timestamp

Output only. The time that this attempt response was received.

response_time will be truncated to the nearest microsecond.

Type

google.protobuf.timestamp_pb2.Timestamp

response_status

Output only. The response from the worker for this attempt.

If response_time is unset, then the task has not been attempted or is currently running and the response_status field is meaningless.

Type

google.rpc.status_pb2.Status

class google.cloud.tasks_v2beta3.types.BufferTaskRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

Request message for [BufferTask][google.cloud.tasks.v2beta3.CloudTasks.BufferTask].

queue

Required. The parent queue name. For example: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID`

The queue must already exist.

Type

str

task_id

Optional. Task ID for the task being created. If not provided, a random task ID is assigned to the task.

Type

str

body

Optional. Body of the HTTP request.

The body can take any generic value. The value is written to the [HttpRequest][payload] of the [Task].

Type

google.api.httpbody_pb2.HttpBody

class google.cloud.tasks_v2beta3.types.BufferTaskResponse(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

Response message for [BufferTask][google.cloud.tasks.v2beta3.CloudTasks.BufferTask].

task

The created task.

Type

google.cloud.tasks_v2beta3.types.Task

class google.cloud.tasks_v2beta3.types.CreateQueueRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

Request message for [CreateQueue][google.cloud.tasks.v2beta3.CloudTasks.CreateQueue].

parent

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][google.cloud.location.Locations.ListLocations].

Type

str

queue

Required. The queue to create.

[Queue’s name][google.cloud.tasks.v2beta3.Queue.name] cannot be the same as an existing queue.

Type

google.cloud.tasks_v2beta3.types.Queue

class google.cloud.tasks_v2beta3.types.CreateTaskRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

Request message for [CreateTask][google.cloud.tasks.v2beta3.CloudTasks.CreateTask].

parent

Required. The queue name. For example: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID

The queue must already exist.

Type

str

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][google.cloud.tasks.v2beta3.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][google.cloud.tasks.v2beta3.Task.name].

If [schedule_time][google.cloud.tasks.v2beta3.Task.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][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 ~1 hour 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 ~9 days after the original task was deleted or executed.

Because there is an extra lookup cost to identify duplicate task names, these [CreateTask][google.cloud.tasks.v2beta3.CloudTasks.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.

Type

google.cloud.tasks_v2beta3.types.Task

response_view

The response_view specifies which subset of the [Task][google.cloud.tasks.v2beta3.Task] will be returned.

By default response_view is [BASIC][google.cloud.tasks.v2beta3.Task.View.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][google.cloud.tasks.v2beta3.Task.View.FULL] requires cloudtasks.tasks.fullView Google IAM permission on the [Task][google.cloud.tasks.v2beta3.Task] resource.

class google.cloud.tasks_v2beta3.types.HttpRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

HTTP request.

The task will be pushed to the worker as an HTTP request. If the worker or the redirected worker acknowledges the task by returning a successful HTTP response code ([200 - 299]), the task will be removed from the queue. If any other HTTP response code is returned or no response is received, the task will be retried according to the following:

• User-specified throttling: [retry configuration][google.cloud.tasks.v2beta3.Queue.retry_config], [rate limits][google.cloud.tasks.v2beta3.Queue.rate_limits], and the [queue’s state][google.cloud.tasks.v2beta3.Queue.state].

• System throttling: To prevent the worker from overloading, Cloud Tasks may temporarily reduce the queue’s effective rate. User-specified settings will not be changed.

System throttling happens because:

• Cloud Tasks backs off on all errors. Normally the backoff specified in [rate limits][google.cloud.tasks.v2beta3.Queue.rate_limits] will be used. But if the worker returns 429 (Too Many Requests), 503 (Service Unavailable), or the rate of errors is high, Cloud Tasks will use a higher backoff rate. The retry specified in the Retry-After HTTP response header is considered.

• To prevent traffic spikes and to smooth sudden increases in traffic, dispatches ramp up slowly when the queue is newly created or idle and if large numbers of tasks suddenly become available to dispatch (due to spikes in create task rates, the queue being unpaused, or many tasks that are scheduled at the same time).

This message has oneof fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.

url

Required. The full url path that the request will be sent to.

This string must begin with either “http://” or “https://”. Some examples are: http://acme.com and https://acme.com/sales:8080. Cloud Tasks will encode some characters for safety and compatibility. The maximum allowed URL length is 2083 characters after encoding.

The Location header response from a redirect response [300 - 399] may be followed. The redirect is not counted as a separate attempt.

Type

str

http_method

The HTTP method to use for the request. The default is POST.

Type

google.cloud.tasks_v2beta3.types.HttpMethod

headers

HTTP request headers.

This map contains the header field names and values. Headers can be set when the [task is created][google.cloud.tasks.v2beta3.CloudTasks.CreateTask].

These headers represent a subset of the headers that will accompany the task’s HTTP request. Some HTTP request headers will be ignored or replaced.

A partial list of headers that will be ignored or replaced is:

• Any header that is prefixed with “X-CloudTasks-” will be treated as service header. Service headers define properties of the task and are predefined in CloudTask.

• Host: This will be computed by Cloud Tasks and derived from [HttpRequest.url][google.cloud.tasks.v2beta3.HttpRequest.url].

• Content-Length: This will be computed by Cloud Tasks.

• User-Agent: This will be set to "Google-Cloud-Tasks".

• X-Google-*: Google use only.

• X-AppEngine-*: Google use only.

Content-Type won’t be set by Cloud Tasks. You can explicitly set Content-Type to a media type when the [task is created][google.cloud.tasks.v2beta3.CloudTasks.CreateTask]. For example, Content-Type can be set to "application/octet-stream" or "application/json".

Headers which can have multiple values (according to RFC2616) can be specified using comma-separated values.

The size of the headers must be less than 80KB.

Type

MutableMapping[str, str]

body

HTTP request body.

A request body is allowed only if the [HTTP method][google.cloud.tasks.v2beta3.HttpRequest.http_method] is POST, PUT, or PATCH. It is an error to set body on a task with an incompatible [HttpMethod][google.cloud.tasks.v2beta3.HttpMethod].

This map contains the header field names and values. Headers will be set when running the [CreateTask][google.cloud.tasks.v2beta3.CloudTasks.CreateTask] and/or [BufferTask][google.cloud.tasks.v2beta3.CloudTasks.BufferTask].

These headers represent a subset of the headers that will be configured for the task’s HTTP request. Some HTTP request headers will be ignored or replaced.

A partial list of headers that will be ignored or replaced is:

• Several predefined headers, prefixed with “X-CloudTasks-”, can be used to define properties of the task.

• Host: This will be computed by Cloud Tasks and derived from [HttpRequest.url][google.cloud.tasks.v2beta3.Target.HttpRequest.url].

• Content-Length: This will be computed by Cloud Tasks.

str

app_engine_http_queue

[AppEngineHttpQueue][google.cloud.tasks.v2beta3.AppEngineHttpQueue] settings apply only to [App Engine tasks][google.cloud.tasks.v2beta3.AppEngineHttpRequest] in this queue. [Http tasks][google.cloud.tasks.v2beta3.HttpRequest] are not affected by this proto.

This field is a member of oneof queue_type.

Type

google.cloud.tasks_v2beta3.types.AppEngineHttpQueue

http_target

Modifies HTTP target for HTTP tasks.

Type

google.cloud.tasks_v2beta3.types.HttpTarget

rate_limits

Rate limits for task dispatches.

[rate_limits][google.cloud.tasks.v2beta3.Queue.rate_limits] and [retry_config][google.cloud.tasks.v2beta3.Queue.retry_config] are related because they both control task attempts. However they control task attempts in different ways:

• [rate_limits][google.cloud.tasks.v2beta3.Queue.rate_limits] controls the total rate of dispatches from a queue (i.e. all traffic dispatched from the queue, regardless of whether the dispatch is from a first attempt or a retry).

• [retry_config][google.cloud.tasks.v2beta3.Queue.retry_config] controls what happens to particular a task after its first attempt fails. That is, [retry_config][google.cloud.tasks.v2beta3.Queue.retry_config] controls task retries (the second attempt, third attempt, etc).

The queue’s actual dispatch rate is the result of:

• Number of tasks in the queue

• User-specified throttling: [rate_limits][google.cloud.tasks.v2beta3.Queue.rate_limits], [retry_config][google.cloud.tasks.v2beta3.Queue.retry_config], and the [queue’s state][google.cloud.tasks.v2beta3.Queue.state].

• System throttling due to 429 (Too Many Requests) or 503 (Service Unavailable) responses from the worker, high error rates, or to smooth sudden large traffic spikes.

Type

google.cloud.tasks_v2beta3.types.RateLimits

retry_config

Settings that determine the retry behavior.

• For tasks created using Cloud Tasks: the queue-level retry settings apply to all tasks in the queue that were created using Cloud Tasks. Retry settings cannot be set on individual tasks.

• For tasks created using the App Engine SDK: the queue-level retry settings apply to all tasks in the queue which do not have retry settings explicitly set on the task and were created by the App Engine SDK. See App Engine documentation.

Type

google.cloud.tasks_v2beta3.types.RetryConfig

state

Output only. The state of the queue.

state can only be changed by called [PauseQueue][google.cloud.tasks.v2beta3.CloudTasks.PauseQueue], [ResumeQueue][google.cloud.tasks.v2beta3.CloudTasks.ResumeQueue], or uploading queue.yaml/xml. [UpdateQueue][google.cloud.tasks.v2beta3.CloudTasks.UpdateQueue] cannot be used to change state.

Type

google.cloud.tasks_v2beta3.types.Queue.State

purge_time

Output only. The last time this queue was purged.

All tasks that were [created][google.cloud.tasks.v2beta3.Task.create_time] before this time were purged.

A queue can be purged using [PurgeQueue][google.cloud.tasks.v2beta3.CloudTasks.PurgeQueue], the App Engine Task Queue SDK, or the Cloud Console.

Purge time will be truncated to the nearest microsecond. Purge time will be unset if the queue has never been purged.

Type

google.protobuf.timestamp_pb2.Timestamp

task_ttl

The maximum amount of time that a task will be retained in this queue.

Queues created by Cloud Tasks have a default task_ttl of 31 days. After a task has lived for task_ttl, the task will be deleted regardless of whether it was dispatched or not.

The task_ttl for queues created via queue.yaml/xml is equal to the maximum duration because there is a storage quota for these queues. To view the maximum valid duration, see the documentation for [Duration][google.protobuf.Duration].

Type

google.protobuf.duration_pb2.Duration

tombstone_ttl

The task tombstone time to live (TTL).

After a task is deleted or executed, the task’s tombstone is retained for the length of time specified by tombstone_ttl. The tombstone is used by task de-duplication; another task with the same name can’t be created until the tombstone has expired. For more information about task de-duplication, see the documentation for [CreateTaskRequest][google.cloud.tasks.v2beta3.CreateTaskRequest.task].

Queues created by Cloud Tasks have a default tombstone_ttl of 1 hour.

Type

google.protobuf.duration_pb2.Duration

Type

google.cloud.tasks_v2beta3.types.QueueStats

class State(value)

Bases: proto.enums.Enum

State of the queue.

Values:

STATE_UNSPECIFIED (0):

Unspecified state.

RUNNING (1):

The queue is running. Tasks can be dispatched.

If the queue was created using Cloud Tasks and the queue has had no activity (method calls or task dispatches) for 30 days, the queue may take a few minutes to re-activate. Some method calls may return [NOT_FOUND][google.rpc.Code.NOT_FOUND] and tasks may not be dispatched for a few minutes until the queue has been re-activated.

PAUSED (2):

Tasks are paused by the user. If the queue is paused then Cloud Tasks will stop delivering tasks from it, but more tasks can still be added to it by the user.

DISABLED (3):

The queue is disabled.

A queue becomes DISABLED when queue.yaml or queue.xml is uploaded which does not contain the queue. You cannot directly disable a queue.

When a queue is disabled, tasks can still be added to a queue but the tasks are not dispatched.

To permanently delete this queue and all of its tasks, call [DeleteQueue][google.cloud.tasks.v2beta3.CloudTasks.DeleteQueue].

class Type(value)

Bases: proto.enums.Enum

The type of the queue.

Values:

TYPE_UNSPECIFIED (0):

Default value.

PULL (1):

A pull queue.

PUSH (2):

A push queue.

class google.cloud.tasks_v2beta3.types.QueueStats(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

Statistics for a queue.

tasks_count

Output only. An estimation of the number of tasks in the queue, that is, the tasks in the queue that haven’t been executed, the tasks in the queue which the queue has dispatched but has not yet received a reply for, and the failed tasks that the queue is retrying.

Type

int

oldest_estimated_arrival_time

Output only. An estimation of the nearest time in the future where a task in the queue is scheduled to be executed.

Type

google.protobuf.timestamp_pb2.Timestamp

executed_last_minute_count

Output only. The number of tasks that the queue has dispatched and received a reply for during the last minute. This variable counts both successful and non-successful executions.

Type

int

concurrent_dispatches_count

Output only. The number of requests that the queue has dispatched but has not received a reply for yet.

Type

int

effective_execution_rate

Output only. The current maximum number of tasks per second executed by the queue. The maximum value of this variable is controlled by the RateLimits of the Queue. However, this value could be less to avoid overloading the endpoints tasks in the queue are targeting.

Type

float

class google.cloud.tasks_v2beta3.types.RateLimits(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

Rate limits.

This message determines the maximum rate that tasks can be dispatched by a queue, regardless of whether the dispatch is a first task attempt or a retry.

Note: The debugging command, [RunTask][google.cloud.tasks.v2beta3.CloudTasks.RunTask], will run a task even if the queue has reached its [RateLimits][google.cloud.tasks.v2beta3.RateLimits].

max_dispatches_per_second

The maximum rate at which tasks are dispatched from this queue.

If unspecified when the queue is created, Cloud Tasks will pick the default.

• For [App Engine queues][google.cloud.tasks.v2beta3.AppEngineHttpQueue], the maximum allowed value is 500.

This field has the same meaning as rate in queue.yaml/xml.

Type

float

max_burst_size

The max burst size.

Max burst size limits how fast tasks in queue are processed when many tasks are in the queue and the rate is high. This field allows the queue to have a high rate so processing starts shortly after a task is enqueued, but still limits resource usage when many tasks are enqueued in a short period of time.

The token bucket algorithm is used to control the rate of task dispatches. Each queue has a token bucket that holds tokens, up to the maximum specified by max_burst_size. Each time a task is dispatched, a token is removed from the bucket. Tasks will be dispatched until the queue’s bucket runs out of tokens. The bucket will be continuously refilled with new tokens based on [max_dispatches_per_second][google.cloud.tasks.v2beta3.RateLimits.max_dispatches_per_second].

The default value of max_burst_size is picked by Cloud Tasks based on the value of [max_dispatches_per_second][google.cloud.tasks.v2beta3.RateLimits.max_dispatches_per_second].

The maximum value of max_burst_size is 500.

For App Engine queues that were created or updated using queue.yaml/xml, max_burst_size is equal to bucket_size. If [UpdateQueue][google.cloud.tasks.v2beta3.CloudTasks.UpdateQueue] is called on a queue without explicitly setting a value for max_burst_size, max_burst_size value will get updated if [UpdateQueue][google.cloud.tasks.v2beta3.CloudTasks.UpdateQueue] is updating [max_dispatches_per_second][google.cloud.tasks.v2beta3.RateLimits.max_dispatches_per_second].

Type

int

max_concurrent_dispatches

The maximum number of concurrent tasks that Cloud Tasks allows to be dispatched for this queue. After this threshold has been reached, Cloud Tasks stops dispatching tasks until the number of concurrent requests decreases.

If unspecified when the queue is created, Cloud Tasks will pick the default.

The maximum allowed value is 5,000.

This field has the same meaning as max_concurrent_requests in queue.yaml/xml.

Type

int

class google.cloud.tasks_v2beta3.types.ResumeQueueRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

Type

str

class google.cloud.tasks_v2beta3.types.RetryConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

Retry config.

These settings determine when a failed task attempt is retried.

max_attempts

Number of attempts per task.

Cloud Tasks will attempt the task max_attempts times (that is, if the first attempt fails, then there will be max_attempts - 1 retries). Must be >= -1.

If unspecified when the queue is created, Cloud Tasks will pick the default.

-1 indicates unlimited attempts.

This field has the same meaning as task_retry_limit in queue.yaml/xml.

Type

int

max_retry_duration

If positive, max_retry_duration specifies the time limit for retrying a failed task, measured from when the task was first attempted. Once max_retry_duration time has passed and the task has been attempted [max_attempts][google.cloud.tasks.v2beta3.RetryConfig.max_attempts] times, no further attempts will be made and the task will be deleted.

If zero, then the task age is unlimited.

If unspecified when the queue is created, Cloud Tasks will pick the default.

max_retry_duration will be truncated to the nearest second.

This field has the same meaning as task_age_limit in queue.yaml/xml.

Type

google.protobuf.duration_pb2.Duration

min_backoff

A task will be [scheduled][google.cloud.tasks.v2beta3.Task.schedule_time] for retry between [min_backoff][google.cloud.tasks.v2beta3.RetryConfig.min_backoff] and [max_backoff][google.cloud.tasks.v2beta3.RetryConfig.max_backoff] duration after it fails, if the queue’s [RetryConfig][google.cloud.tasks.v2beta3.RetryConfig] specifies that the task should be retried.

If unspecified when the queue is created, Cloud Tasks will pick the default.

min_backoff will be truncated to the nearest second.

This field has the same meaning as min_backoff_seconds in queue.yaml/xml.

Type

google.protobuf.duration_pb2.Duration

max_backoff

A task will be [scheduled][google.cloud.tasks.v2beta3.Task.schedule_time] for retry between [min_backoff][google.cloud.tasks.v2beta3.RetryConfig.min_backoff] and [max_backoff][google.cloud.tasks.v2beta3.RetryConfig.max_backoff] duration after it fails, if the queue’s [RetryConfig][google.cloud.tasks.v2beta3.RetryConfig] specifies that the task should be retried.

If unspecified when the queue is created, Cloud Tasks will pick the default.

max_backoff will be truncated to the nearest second.

This field has the same meaning as max_backoff_seconds in queue.yaml/xml.

Type

google.protobuf.duration_pb2.Duration

max_doublings

The time between retries will double max_doublings times.

A task’s retry interval starts at [min_backoff][google.cloud.tasks.v2beta3.RetryConfig.min_backoff], then doubles max_doublings times, then increases linearly, and finally retries at intervals of [max_backoff][google.cloud.tasks.v2beta3.RetryConfig.max_backoff] up to [max_attempts][google.cloud.tasks.v2beta3.RetryConfig.max_attempts] times.

For example, if [min_backoff][google.cloud.tasks.v2beta3.RetryConfig.min_backoff] is 10s, [max_backoff][google.cloud.tasks.v2beta3.RetryConfig.max_backoff] is 300s, and max_doublings is 3, then the a task will first be retried in 10s. The retry interval will double three times, and then increase linearly by 2^3 * 10s. Finally, the task will retry at intervals of [max_backoff][google.cloud.tasks.v2beta3.RetryConfig.max_backoff] until the task has been attempted [max_attempts][google.cloud.tasks.v2beta3.RetryConfig.max_attempts] times. Thus, the requests will retry at 10s, 20s, 40s, 80s, 160s, 240s, 300s, 300s, ….

If unspecified when the queue is created, Cloud Tasks will pick the default.

This field has the same meaning as max_doublings in queue.yaml/xml.

response_view

The response_view specifies which subset of the [Task][google.cloud.tasks.v2beta3.Task] will be returned.

By default response_view is [BASIC][google.cloud.tasks.v2beta3.Task.View.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][google.cloud.tasks.v2beta3.Task.View.FULL] requires cloudtasks.tasks.fullView Google IAM permission on the [Task][google.cloud.tasks.v2beta3.Task] resource.

Pull Message contained in a task in a [PULL][google.cloud.tasks.v2beta3.Queue.type] queue type. This payload type cannot be explicitly set through Cloud Tasks API. Its purpose, currently is to provide backward compatibility with App Engine Task Queue pull queues to provide a way to inspect contents of pull tasks through the [CloudTasks.GetTask][google.cloud.tasks.v2beta3.CloudTasks.GetTask].

This field is a member of oneof payload_type.

Type

google.cloud.tasks_v2beta3.types.PullMessage

schedule_time

For App Engine queues, this is when the task will be attempted or retried.

schedule_time will be truncated to the nearest microsecond.

Type

google.protobuf.timestamp_pb2.Timestamp

create_time

Output only. The time that the task was created.

create_time will be truncated to the nearest second.

Type

google.protobuf.timestamp_pb2.Timestamp

dispatch_deadline

The deadline for requests sent to the worker. If the worker does not respond by this deadline then the request is cancelled and the attempt is marked as a DEADLINE_EXCEEDED failure. Cloud Tasks will retry the task according to the [RetryConfig][google.cloud.tasks.v2beta3.RetryConfig].

Note that when the request is cancelled, Cloud Tasks will stop listening for the response, but whether the worker stops processing depends on the worker. For example, if the worker is stuck, it may not react to cancelled requests.

The default and maximum values depend on the type of request:

• For [HTTP tasks][google.cloud.tasks.v2beta3.HttpRequest], the default is 10 minutes. The deadline must be in the interval [15 seconds, 30 minutes].

• For [App Engine tasks][google.cloud.tasks.v2beta3.AppEngineHttpRequest], 0 indicates that the request has the default deadline. The default deadline depends on the scaling type of the service: 10 minutes for standard apps with automatic scaling, 24 hours for standard apps with manual and basic scaling, and 60 minutes for flex apps. If the request deadline is set, it must be in the interval [15 seconds, 24 hours 15 seconds]. Regardless of the task’s dispatch_deadline, the app handler will not run for longer than than the service’s timeout. We recommend setting the dispatch_deadline to at most a few seconds more than the app handler’s timeout. For more information see Timeouts.

dispatch_deadline will be truncated to the nearest millisecond. The deadline is an approximate deadline.

The basic view omits fields which can be large or can contain sensitive data.

This view does not include the [body in AppEngineHttpRequest][google.cloud.tasks.v2beta3.AppEngineHttpRequest.body]. Bodies are desirable to return only when needed, because they can be large and because of the sensitivity of the data that you choose to store in it.

FULL (2):

All information is returned.

Authorization for [FULL][google.cloud.tasks.v2beta3.Task.View.FULL] requires cloudtasks.tasks.fullView Google IAM permission on the [Queue][google.cloud.tasks.v2beta3.Queue] resource.

class google.cloud.tasks_v2beta3.types.UpdateQueueRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

Request message for [UpdateQueue][google.cloud.tasks.v2beta3.CloudTasks.UpdateQueue].

queue

Required. The queue to create or update.

The queue’s [name][google.cloud.tasks.v2beta3.Queue.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][google.cloud.tasks.v2beta3.Queue.name] cannot be changed.

Type

google.cloud.tasks_v2beta3.types.Queue

update_mask

A mask used to specify which fields of the queue are being updated. If empty, then all fields will be updated.

Type

google.protobuf.field_mask_pb2.FieldMask

class google.cloud.tasks_v2beta3.types.UriOverride(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Bases: proto.message.Message

URI Override.

When specified, all the HTTP tasks inside the queue will be partially or fully overridden depending on the configured values.

scheme

Scheme override.

When specified, the task URI scheme is replaced by the provided value (HTTP or HTTPS).

This field is a member of oneof _scheme.

Type

google.cloud.tasks_v2beta3.types.UriOverride.Scheme

host

Host override.

When specified, replaces the host part of the task URL. For example, if the task URL is “https://www.google.com,” and host value is set to “example.net”, the overridden URI will be changed to “https://example.net.” Host value cannot be an empty string (INVALID_ARGUMENT).

This field is a member of oneof _host.

Type

str

port

Port override.

When specified, replaces the port part of the task URI. For instance, for a URI http://www.google.com/foo and port=123, the overridden URI becomes http://www.google.com:123/foo. Note that the port value must be a positive integer. Setting the port to 0 (Zero) clears the URI port.

This field is a member of oneof _port.

Type

int

path_override

URI path.

When specified, replaces the existing path of the task URL. Setting the path value to an empty string clears the URI path segment.

Type

google.cloud.tasks_v2beta3.types.PathOverride

query_override

URI Query.

When specified, replaces the query part of the task URI. Setting the query value to an empty string clears the URI query segment.

Type

google.cloud.tasks_v2beta3.types.QueryOverride

uri_override_enforce_mode

URI Override Enforce Mode

When specified, determines the Target UriOverride mode. If not specified, it defaults to ALWAYS.

Type

google.cloud.tasks_v2beta3.types.UriOverride.UriOverrideEnforceMode

class Scheme(value)

class UriOverrideEnforceMode(value)

Bases: proto.enums.Enum

UriOverrideEnforceMode mode is to define enforcing mode for the override modes.

Values:

URI_OVERRIDE_ENFORCE_MODE_UNSPECIFIED (0):

OverrideMode Unspecified. Defaults to ALWAYS.

IF_NOT_EXISTS (1):

In the IF_NOT_EXISTS mode, queue-level configuration is only applied where task-level configuration does not exist.

ALWAYS (2):

In the ALWAYS mode, queue-level configuration overrides all task-level configuration
