(static, constant) HttpMethod :number

The HTTP method used to execute the task.

Properties:
Name Type Description
HTTP_METHOD_UNSPECIFIED number

HTTP method unspecified

POST number

HTTP POST

GET number

HTTP GET

HEAD number

HTTP HEAD

PUT number

HTTP PUT

DELETE number

HTTP DELETE

Source:

(static) State :number

State of the queue.

Properties:
Name Type Description
STATE_UNSPECIFIED number

Unspecified state.

RUNNING number

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 and tasks may not be dispatched for a few minutes until the queue has been re-activated.

PAUSED number

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. When a pull queue is paused, all LeaseTasks calls will return a FAILED_PRECONDITION.

DISABLED number

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 and LeaseTasks calls return a FAILED_PRECONDITION error.

To permanently delete this queue and all of its tasks, call DeleteQueue.

(static) View :number

The view specifies a subset of Task data.

When a task is returned in a response, 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.

Properties:
Name Type Description
VIEW_UNSPECIFIED number

Unspecified. Defaults to BASIC.

BASIC number

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

This view does not include the (payload in AppEngineHttpRequest and payload in PullMessage). These payloads 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 number

All information is returned.

Authorization for FULL requires cloudtasks.tasks.fullView Google IAM permission on the Queue resource.

Type Definitions

AcknowledgeTaskRequest

Request message for acknowledging a task using AcknowledgeTask.

Properties:
Name Type Description
name string

Required. The task name. For example: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID

scheduleTime Object

Required. The task's current schedule time, available in the schedule_time returned by LeaseTasks response or RenewLease response. This restriction is to ensure that your worker currently holds the lease.

This object should have the same structure as Timestamp

See:

AppEngineHttpRequest

App Engine HTTP request.

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

This proto can only be used for tasks in a queue which has app_engine_http_target set.

Using AppEngineHttpRequest requires appengine.applications.get 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 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 is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing.

The url that the task will be sent to is:

  • url = host + relative_url

Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with login: admin. Because tasks are not run as any user, they cannot be dispatched to URIs restricted with login: required 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. Failed tasks will be retried according to the retry configuration. 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.

Properties:
Name Type Description
httpMethod number

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 will fail with error code 405 (Method Not Allowed). See Writing a push task request handler and the documentation for the request handlers in the language your app is written in e.g. Python Request Handler.

The number should be among the values of HttpMethod

appEngineRouting Object

Task-level setting for 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.

This object should have the same structure as AppEngineRouting

relativeUrl string

The relative URL.

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

headers Object.<string, string>

HTTP request headers.

This map contains the header field names and values. Headers can be set when the task is created. 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 payload, 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. 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. For more information, see the CreateTask documentation.

payload Buffer

Payload.

The payload will be sent as the HTTP message body. A message body, and thus a payload, is allowed only if the HTTP method is POST or PUT. It is an error to set a data payload on a task with an incompatible HttpMethod.

Source:
See:

AppEngineHttpTarget

App Engine HTTP target.

The task will be delivered to the App Engine application hostname specified by its AppEngineHttpTarget and AppEngineHttpRequest. The documentation for AppEngineHttpRequest explains how the task's host URL is constructed.

Using AppEngineHttpTarget requires appengine.applications.get Google IAM permission for the project and the following scope:

AppEngineRouting

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.

Properties:
Name Type Description
service string

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 is not parsable into service, version, and 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 is not parsable, then service, version, and instance are the empty string.

version string

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 is not parsable into service, version, and 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 is not parsable, then service, version, and instance are the empty string.

instance string

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.

host string

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

For more information, see How Requests are Routed.

The host is constructed as:

  • host = [application_domain_name]
    | [service] + '.' + [application_domain_name]
    | [version] + '.' + [application_domain_name]
    | [version_dot_service]+ '.' + [application_domain_name]
    | [instance] + '.' + [application_domain_name]
    | [instance_dot_service] + '.' + [application_domain_name]
    | [instance_dot_version] + '.' + [application_domain_name]
    | [instance_dot_version_dot_service] + '.' + [application_domain_name]

  • application_domain_name = The domain name of the app, for example .appspot.com, which is associated with the queue's project ID. Some tasks which were created using the App Engine SDK use a custom domain name.

  • service = service

  • version = version

  • version_dot_service = version + '.' + service

  • instance = instance

  • instance_dot_service = instance + '.' + service

  • instance_dot_version = instance + '.' + version

  • instance_dot_version_dot_service = instance + '.' + version + '.' + service

If service is empty, then the task will be sent to the service which is the default service when the task is attempted.

If version is empty, then the task will be sent to the version which is the default version when the task is attempted.

If instance is empty, then the task will be sent to an instance which is available when the task is attempted.

If service, version, or instance is invalid, then the task will be sent to the default version of the default service when the task is attempted.

CreateQueueRequest

Request message for CreateQueue.

Properties:
Name Type Description
parent string

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 Object

Required. The queue to create.

Queue's name cannot be the same as an existing queue.

This object should have the same structure as Queue

Source:
See:

CreateTaskRequest

Request message for CreateTask.

Properties:
Name Type Description
parent string

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

The queue must already exist.

task Object

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. 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.

responseView number

maxTasks number

The maximum number of tasks to lease.

The system will make a best effort to return as close to as max_tasks as possible.

The largest that max_tasks can be is 1000.

The maximum total size of a lease tasks response is 32 MB. If the sum of all task sizes requested reaches this limit, fewer tasks than requested are returned.

leaseDuration Object

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.

The number should be among the values of View

filter string

filter can be used to specify a subset of tasks to lease.

When filter is set to tag=<my-tag> then the response will contain only tasks whose tag is equal to <my-tag>. <my-tag> must be less than 500 characters.

When filter is set to tag_function=oldest_tag(), only tasks which have the same tag as the task with the oldest schedule_time will be returned.

Grammar Syntax:

  • filter = "tag=" tag | "tag_function=" function

  • tag = string

  • function = "oldest_tag()"

The oldest_tag() function returns tasks which have the same tag as the oldest task (ordered by schedule time).

SDK compatibility: Although the SDK allows tags to be either string or bytes, only UTF-8 encoded tags can be used in Cloud Tasks. Tag which aren't UTF-8 encoded can't be used in the filter and the task's tag will be displayed as empty in Cloud Tasks.

filter string

filter can be used to specify a subset of queues. Any Queue field can be used as a filter and several operators as supported. For example: <=, <, >=, >, !=, =, :. The filter syntax is the same as described in Stackdriver's Advanced Logs Filters.

Sample filter "app_engine_http_target: *".

Note that using filters might cause fewer queues than the requested_page size to be returned.

pageSize number

Requested page size.

The maximum page size is 9800. If unspecified, the page size will be the maximum. Fewer queues than requested might be returned, even if more queues exist; use the next_page_token in the response to determine if more queues exist.

pageToken string

A token identifying the page of results to return.

rateLimits Object

Rate limits for task dispatches.

rate_limits and retry_config are related because they both control task attempts however they control how tasks are attempted in different ways:

  • 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 controls what happens to particular a task after its first attempt fails. That is, retry_config controls task retries (the second attempt, third attempt, etc).

This object should have the same structure as RateLimits

retryConfig Object

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.

RateLimits

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, will run a task even if the queue has reached its RateLimits.

Properties:
Name Type Description
maxTasksDispatchedPerSecond number

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, the maximum allowed value is 500.
  • This field is output only for pull queues. In addition to the max_tasks_dispatched_per_second limit, a maximum of 10 QPS of LeaseTasks requests are allowed per pull queue.

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

maxBurstSize number

Output only. 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_tasks_dispatched_per_second.

Cloud Tasks will pick the value of max_burst_size based on the value of max_tasks_dispatched_per_second.

For App Engine queues that were created or updated using queue.yaml/xml, max_burst_size is equal to bucket_size. Since max_burst_size is output only, if UpdateQueue is called on a queue created by queue.yaml/xml, max_burst_size will be reset based on the value of max_tasks_dispatched_per_second, regardless of whether max_tasks_dispatched_per_second is updated.

maxConcurrentTasks number

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 is output only for pull queues and always -1, which indicates no limit. No other queue types can have max_concurrent_tasks set to -1.

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

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 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.

This field is output only for pull queues.

max_retry_duration will be truncated to the nearest second.

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

This object should have the same structure as Duration

minBackoff Object

A task will be scheduled for retry between min_backoff and max_backoff duration after it fails, if the queue's RetryConfig specifies that the task should be retried.

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

This field is output only for pull queues.

min_backoff will be truncated to the nearest second.

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

This object should have the same structure as Duration

maxBackoff Object

A task will be scheduled for retry between min_backoff and max_backoff duration after it fails, if the queue's RetryConfig specifies that the task should be retried.

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

This field is output only for pull queues.

max_backoff will be truncated to the nearest second.

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

This object should have the same structure as Duration

maxDoublings number

The time between retries will double max_doublings times.

A task's retry interval starts at min_backoff, then doubles max_doublings times, then increases linearly, and finally retries retries at intervals of max_backoff up to max_attempts times.

For example, if min_backoff is 10s, 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 until the task has been attempted 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 is output only for pull queues.

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

RunTaskRequest

Request message for forcing a task to run now using RunTask.

Properties:
Name Type Description
name string

Required. The task name. For example: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID

responseView number

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 permission on the Task resource.

The number should be among the values of View

Task

A unit of scheduled work.

Properties:
Name Type Description
name string

Optionally caller-specified in CreateTask.

The task name.

The task name must have the following format: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID

  • PROJECT_ID can contain letters ([A-Za-z]), numbers ([0-9]), hyphens (-), colons (:), or periods (.). For more information, see Identifying projects
  • LOCATION_ID is the canonical ID for the task's location. The list of available locations can be obtained by calling ListLocations. For more information, see https://cloud.google.com/about/locations/.
  • QUEUE_ID can contain letters ([A-Za-z]), numbers ([0-9]), or hyphens (-). The maximum length is 100 characters.
  • TASK_ID can contain only letters ([A-Za-z]), numbers ([0-9]), hyphens (-), or underscores (_). The maximum length is 500 characters.
appEngineHttpRequest Object

App Engine HTTP request that is sent to the task's target. Can be set only if app_engine_http_target is set on the queue.

An App Engine task is a task that has AppEngineHttpRequest set.

This object should have the same structure as AppEngineHttpRequest

pullMessage Object

LeaseTasks to process the task. Can be set only if pull_target is set on the queue.

A pull task is a task that has PullMessage set.

This object should have the same structure as PullMessage

scheduleTime Object

The time when the task is scheduled to be attempted.

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

For pull queues, this is the time when the task is available to be leased; if a task is currently leased, this is the time when the current lease expires, that is, the time that the task was leased plus the lease_duration.

schedule_time will be truncated to the nearest microsecond.

This object should have the same structure as Timestamp

createTime Object

Output only. The time that the task was created.

create_time will be truncated to the nearest second.

This object should have the same structure as Timestamp

status Object

Output only. The task status.

This object should have the same structure as TaskStatus

view number

Output only. The view specifies which subset of the Task has been returned.

The number should be among the values of View
