Class Queue (2.12.0)

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.

.. _oneof:


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
AppEngineHttpQueue settings apply only to [App Engine tasks][] in this queue. [Http tasks][] are not affected by this proto. This field is a member of oneof_ queue_type.
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][]. - 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.
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
Output only. The state of the queue. state can only be changed by calling PauseQueue, ResumeQueue, or uploading queue.yaml/xml __. UpdateQueue cannot be used to change state.
purge_time google.protobuf.timestamp_pb2.Timestamp
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
task_ttl google.protobuf.duration_pb2.Duration
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
tombstone_ttl google.protobuf.duration_pb2.Duration
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. Queues created by Cloud Tasks have a default tombstone_ttl of 1 hour.
Configuration options for writing logs to `Stackdriver Logging
Immutable. The type of a queue (push or pull). Queue.type is an immutable property of the queue that is set at the queue creation time. When left unspecified, the default value of PUSH is selected.
Output only. The realtime, informational statistics for a queue. In order to receive the statistics the caller should include this field in the FieldMask.




State of the queue.
