  • Method Details

    • listQueues

      default void listQueues(ListQueuesRequest request, io.grpc.stub.StreamObserver<ListQueuesResponse> responseObserver)
       Lists queues.
       Queues are returned in lexicographical order.
       
    • getQueue

      default void getQueue(GetQueueRequest request, io.grpc.stub.StreamObserver<Queue> responseObserver)
       Gets a queue.
       
    • createQueue

      default void createQueue(CreateQueueRequest request, io.grpc.stub.StreamObserver<Queue> responseObserver)
       Creates a queue.
       Queues created with this method allow tasks to live for a maximum of 31
       days. After a task is 31 days old, the task will be deleted regardless of
       whether it was dispatched or not.
       WARNING: Using this method may have unintended side effects if you are
       using an App Engine `queue.yaml` or `queue.xml` file to manage your queues.
       Read
       [Overview of Queue Management and
       queue.yaml](https://cloud.google.com/tasks/docs/queue-yaml) before using
       this method.
       
    • updateQueue

      default void updateQueue(UpdateQueueRequest request, io.grpc.stub.StreamObserver<Queue> responseObserver)
       Updates a queue.
       This method creates the queue if it does not exist and updates
       the queue if it does exist.
       Queues created with this method allow tasks to live for a maximum of 31
       days. After a task is 31 days old, the task will be deleted regardless of
       whether it was dispatched or not.
       WARNING: Using this method may have unintended side effects if you are
       using an App Engine `queue.yaml` or `queue.xml` file to manage your queues.

       this method.
       
    • deleteQueue

      default void deleteQueue(DeleteQueueRequest request, io.grpc.stub.StreamObserver<com.google.protobuf.Empty> responseObserver)
       Deletes a queue.
       This command will delete the queue even if it has tasks in it.
       Note: If you delete a queue, a queue with the same name can't be created
       for 7 days.
       WARNING: Using this method may have unintended side effects if you are
       using an App Engine `queue.yaml` or `queue.xml` file to manage your queues.

       this method.
       
    • purgeQueue

      default void purgeQueue(PurgeQueueRequest request, io.grpc.stub.StreamObserver<Queue> responseObserver)
       Purges a queue by deleting all of its tasks.
       All tasks created before this method is called are permanently deleted.
       Purge operations can take up to one minute to take effect. Tasks
       might be dispatched before the purge takes effect. A purge is irreversible.
       
    • pauseQueue

      default void pauseQueue(PauseQueueRequest request, io.grpc.stub.StreamObserver<Queue> responseObserver)
       Pauses the queue.
       If a queue is paused then the system will stop dispatching tasks
       until the queue is resumed via
       [ResumeQueue][google.cloud.tasks.v2beta3.CloudTasks.ResumeQueue]. Tasks can
       still be added when the queue is paused. A queue is paused if its
       [state][google.cloud.tasks.v2beta3.Queue.state] is
       [PAUSED][google.cloud.tasks.v2beta3.Queue.State.PAUSED].
       
    • resumeQueue

      default void resumeQueue(ResumeQueueRequest request, io.grpc.stub.StreamObserver<Queue> responseObserver)
       Resume a queue.
       This method resumes a queue after it has been
       [PAUSED][google.cloud.tasks.v2beta3.Queue.State.PAUSED] or
       [DISABLED][google.cloud.tasks.v2beta3.Queue.State.DISABLED]. 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](https://cloud.google.com/tasks/docs/manage-cloud-task-scaling).
       
    • getIamPolicy

      default void getIamPolicy(GetIamPolicyRequest request, io.grpc.stub.StreamObserver<Policy> responseObserver)
       Gets the access control policy for a
       [Queue][google.cloud.tasks.v2beta3.Queue]. Returns an empty policy if the
       resource exists and does not have a policy set.
       Authorization requires the following
       [Google IAM](https://cloud.google.com/iam) permission on the specified
       resource parent:
       * `cloudtasks.queues.getIamPolicy`
       
    • setIamPolicy

      default void setIamPolicy(SetIamPolicyRequest request, io.grpc.stub.StreamObserver<Policy> responseObserver)
       Sets the access control policy for a
       [Queue][google.cloud.tasks.v2beta3.Queue]. Replaces any existing policy.
       Note: The Cloud Console does not check queue-level IAM permissions yet.
       Project-level permissions are required to use the Cloud Console.
       Authorization requires the following
       [Google IAM](https://cloud.google.com/iam) permission on the specified
       resource parent:
       * `cloudtasks.queues.setIamPolicy`
       
    • testIamPermissions

      default void testIamPermissions(TestIamPermissionsRequest request, io.grpc.stub.StreamObserver<TestIamPermissionsResponse> responseObserver)
       Returns permissions that a caller has on a
       [Queue][google.cloud.tasks.v2beta3.Queue]. If the resource does not exist,
       this will return an empty set of permissions, not a
       [NOT_FOUND][google.rpc.Code.NOT_FOUND] error.
       Note: This operation is designed to be used for building permission-aware
       UIs and command-line tools, not for authorization checking. This operation
       may "fail open" without warning.
       
    • listTasks

      default void listTasks(ListTasksRequest request, io.grpc.stub.StreamObserver<ListTasksResponse> responseObserver)
       Lists the tasks in a queue.
       By default, only the [BASIC][google.cloud.tasks.v2beta3.Task.View.BASIC]
       view is retrieved due to performance considerations;
       [response_view][google.cloud.tasks.v2beta3.ListTasksRequest.response_view]
       controls the subset of information which is returned.
       The tasks may be returned in any order. The ordering may change at any
       time.
       
    • getTask

      default void getTask(GetTaskRequest request, io.grpc.stub.StreamObserver<Task> responseObserver)
       Gets a task.
       
    • createTask

      default void createTask(CreateTaskRequest request, io.grpc.stub.StreamObserver<Task> responseObserver)
       Creates a task and adds it to a queue.
       Tasks cannot be updated after creation; there is no UpdateTask command.
       * The maximum task size is 100KB.
       
    • deleteTask

      default void deleteTask(DeleteTaskRequest request, io.grpc.stub.StreamObserver<com.google.protobuf.Empty> responseObserver)
       Deletes a task.
       A task can be deleted if it is scheduled or dispatched. A task
       cannot be deleted if it has executed successfully or permanently
       failed.
       
    • runTask

      default void runTask(RunTaskRequest request, io.grpc.stub.StreamObserver<Task> responseObserver)
       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.
