getRateLimits()

public RateLimits getRateLimits()

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.

.google.cloud.tasks.v2beta3.RateLimits rate_limits = 4;

Returns
Type Description
RateLimits

The rateLimits.

getTaskTtl()

public Duration getTaskTtl()

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.
