The state of a queue is stored in the queue's [state][google.cloud.tasks.v2beta3.Queue.state]; after calling this method it will be set to [RUNNING][google.cloud.tasks.v2beta3.Queue.State.RUNNING].

WARNING: Resuming many high-QPS queues at the same time can lead to target overloading. If you are resuming high-QPS queues, follow the 500/50/5 pattern described in Managing Cloud Tasks Scaling Risks.

Overrides

RunTask(RunTaskRequest, CallSettings)

public override Task RunTask(RunTaskRequest request, CallSettings callSettings = null)

Forces a task to run now.

When this method is called, Cloud Tasks will dispatch the task, even if the task is already running, the queue has reached its [RateLimits][google.cloud.tasks.v2beta3.RateLimits] or is [PAUSED][google.cloud.tasks.v2beta3.Queue.State.PAUSED].

This command is meant to be used for manual debugging. For example, [RunTask][google.cloud.tasks.v2beta3.CloudTasks.RunTask] can be used to retry a failed task after a fix has been made or to manually force a task to be dispatched now.

The dispatched task is returned. That is, the task that is returned contains the [status][Task.status] after the task is dispatched but before the task is received by its target.

If Cloud Tasks receives a successful response from the task's target, then the task will be deleted; otherwise the task's [schedule_time][google.cloud.tasks.v2beta3.Task.schedule_time] will be reset to the time that [RunTask][google.cloud.tasks.v2beta3.CloudTasks.RunTask] was called plus the retry delay specified in the queue's [RetryConfig][google.cloud.tasks.v2beta3.RetryConfig].

[RunTask][google.cloud.tasks.v2beta3.CloudTasks.RunTask] returns [NOT_FOUND][google.rpc.Code.NOT_FOUND] when it is called on a task that has already succeeded or permanently failed.
