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, will run a task even if the queue has reached its RateLimits.

#max_burst_size
def max_burst_size() -> ::Integer
-
(::Integer) — 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 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. If UpdateQueue is called on a queue without explicitly setting a value formax_burst_size
,max_burst_size
value will get updated if UpdateQueue is updating [max_dispatches_per_second][RateLimits.max_dispatches_per_second].

#max_concurrent_tasks
def max_concurrent_tasks() -> ::Integer
-
(::Integer) — 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 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.

- For App Engine queues, the maximum allowed value is 500.

This field has the same meaning as rate in queue.yaml/xml.
