#purge_time ⇒ Google::Protobuf::Timestamp

Returns 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.

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

#rate_limits ⇒ Google::Cloud::Tasks::V2beta3::RateLimits

Returns 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.

Returns:

  • (Google::Cloud::Tasks::V2beta3::RateLimits) —

#retry_config ⇒ Google::Cloud::Tasks::V2beta3::RetryConfig

Returns 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.

Returns:
