  • All Implemented Interfaces:

    public final class RateLimits
extends com.google.protobuf.GeneratedMessageV3
implements RateLimitsOrBuilder
     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][google.cloud.tasks.v2beta2.CloudTasks.RunTask], will run a task
 even if the queue has reached its
 [RateLimits][google.cloud.tasks.v2beta2.RateLimits].

      • getMaxTasksDispatchedPerSecond

        public double getMaxTasksDispatchedPerSecond()
         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][google.cloud.tasks.v2beta2.AppEngineHttpTarget],
 the maximum allowed value
   is 500.
 * This field is output only   for [pull
 queues][google.cloud.tasks.v2beta2.PullTarget]. In addition to the
   `max_tasks_dispatched_per_second` limit, a maximum of 10 QPS of
   [LeaseTasks][google.cloud.tasks.v2beta2.CloudTasks.LeaseTasks] requests
   are allowed per pull queue.


 This field has the same meaning as
 [rate in
 queue.yaml/xml](https://cloud.google.com/appengine/docs/standard/python/config/queueref#rate).
        double max_tasks_dispatched_per_second = 1;
        Specified by:
        getMaxTasksDispatchedPerSecond in interface RateLimitsOrBuilder
        Returns:
        The maxTasksDispatchedPerSecond.

      • getMaxBurstSize

        public int getMaxBurstSize()
         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](https://wikipedia.org/wiki/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_dispatches_per_second][RateLimits.max_dispatches_per_second].

 The default value of `max_burst_size` is picked by Cloud Tasks
 based on the value of
 [max_dispatches_per_second][RateLimits.max_dispatches_per_second].

 The maximum value of `max_burst_size` is 500.

 For App Engine queues that were created or updated using
 `queue.yaml/xml`, `max_burst_size` is equal to
 [bucket_size](https://cloud.google.com/appengine/docs/standard/python/config/queueref#bucket_size).
 If
 [UpdateQueue][google.cloud.tasks.v2beta2.CloudTasks.UpdateQueue] is called
 on a queue without explicitly setting a value for `max_burst_size`,
 `max_burst_size` value will get updated if
 [UpdateQueue][google.cloud.tasks.v2beta2.CloudTasks.UpdateQueue] is
 updating [max_dispatches_per_second][RateLimits.max_dispatches_per_second].
        int32 max_burst_size = 2;
        Specified by:
        getMaxBurstSize in interface RateLimitsOrBuilder
        Returns:
        The maxBurstSize.

      • getMaxConcurrentTasks

        public int getMaxConcurrentTasks()
         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][google.cloud.tasks.v2beta2.PullTarget] 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](https://cloud.google.com/appengine/docs/standard/python/config/queueref#max_concurrent_requests).
        int32 max_concurrent_tasks = 3;
        Specified by:
        getMaxConcurrentTasks in interface RateLimitsOrBuilder
        Returns:
        The maxConcurrentTasks.
