Queue(mapping=None, *, ignore_unknown_fields=False, **kwargs)A queue is a container of related tasks. Queues are configured to manage how those tasks are dispatched. Configurable properties include rate limits, retry options, queue types, and others.
Attributes
| Name | Description |
name |
str
Caller-specified and required in CreateQueue, after which it becomes output only. The queue name. The queue name must have the following format: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID
- PROJECT_ID can contain letters ([A-Za-z]), numbers
([0-9]), hyphens (-), colons (:), or periods (.). For
more information, see `Identifying
projects |
app_engine_routing_override |
Overrides for [task-level app_engine_routing][google.cloud.tasks.v2.AppEngineHttpRequest.app_engine_routing]. These settings apply only to [App Engine tasks][google.cloud.tasks.v2.AppEngineHttpRequest] in this queue. Http tasks are not affected. If set, app_engine_routing_override is used for all [App
Engine tasks][google.cloud.tasks.v2.AppEngineHttpRequest] in
the queue, no matter what the setting is for the [task-level
app_engine_routing][google.cloud.tasks.v2.AppEngineHttpRequest.app_engine_routing].

rate_limits |
Rate limits for task dispatches. rate_limits and retry_config are related because they both control task attempts. However they control task attempts 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). The queue's actual dispatch rate is the result of: - Number of tasks in the queue - User-specified throttling: rate_limits, retry_config, and the [queue's state][google.cloud.tasks.v2.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.

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 |
state |
Output only. The state of the queue. state can only be changed by called
PauseQueue,
ResumeQueue,
or uploading
queue.yaml/xml __.
UpdateQueue
cannot be used to change state.
|
purge_time |
Output only. The last time this queue was purged. All tasks that were created before this time were purged. A queue can be purged using PurgeQueue, the `App Engine Task Queue SDK, or the Cloud Console |
stackdriver_logging_config |
Configuration options for writing logs to `Stackdriver Logging |
