createQueue(CreateQueueRequest request, StreamObserver<Queue> responseObserver)
public void createQueue(CreateQueueRequest request, 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 before using
this method.
createTask(CreateTaskRequest request, StreamObserver<Task> responseObserver)
public void createTask(CreateTaskRequest request, 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.
deleteQueue(DeleteQueueRequest request, StreamObserver<Empty> responseObserver)
public void deleteQueue(DeleteQueueRequest request, StreamObserver<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.
Read
Overview of Queue Management and
queue.yaml before using
this method.
deleteTask(DeleteTaskRequest request, StreamObserver<Empty> responseObserver)
public void deleteTask(DeleteTaskRequest request, StreamObserver<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.
getIamPolicy(GetIamPolicyRequest request, StreamObserver<Policy> responseObserver)
public void getIamPolicy(GetIamPolicyRequest request, StreamObserver<Policy> responseObserver)
Gets the access control policy for a Queue.
Returns an empty policy if the resource exists and does not have a policy
set.
Authorization requires the following
Google IAM permission on the specified
resource parent:
cloudtasks.queues.getIamPolicy
| Parameters |
|---|
| Name | Description |
request | com.google.iam.v1.GetIamPolicyRequest
|
responseObserver | io.grpc.stub.StreamObserver<com.google.iam.v1.Policy>
|
getQueue(GetQueueRequest request, StreamObserver<Queue> responseObserver)
public void getQueue(GetQueueRequest request, StreamObserver<Queue> responseObserver)
getTask(GetTaskRequest request, StreamObserver<Task> responseObserver)
public void getTask(GetTaskRequest request, StreamObserver<Task> responseObserver)
| Parameters |
|---|
| Name | Description |
request | GetTaskRequest
|
responseObserver | io.grpc.stub.StreamObserver<Task>
|
listQueues(ListQueuesRequest request, StreamObserver<ListQueuesResponse> responseObserver)
public void listQueues(ListQueuesRequest request, StreamObserver<ListQueuesResponse> responseObserver)
Lists queues.
Queues are returned in lexicographical order.
listTasks(ListTasksRequest request, StreamObserver<ListTasksResponse> responseObserver)
public void listTasks(ListTasksRequest request, StreamObserver<ListTasksResponse> responseObserver)
Lists the tasks in a queue.
By default, only the BASIC view is retrieved
due to performance considerations;
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.
pauseQueue(PauseQueueRequest request, StreamObserver<Queue> responseObserver)
public void pauseQueue(PauseQueueRequest request, 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. Tasks can still be added
when the queue is paused. A queue is paused if its
state is PAUSED.
purgeQueue(PurgeQueueRequest request, StreamObserver<Queue> responseObserver)
public void purgeQueue(PurgeQueueRequest request, 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.
resumeQueue(ResumeQueueRequest request, StreamObserver<Queue> responseObserver)
public void resumeQueue(ResumeQueueRequest request, StreamObserver<Queue> responseObserver)
Resume a queue.
This method resumes a queue after it has been
PAUSED or
DISABLED. The state of a queue is stored
in the queue's state; after calling this method it
will be set to 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.
runTask(RunTaskRequest request, StreamObserver<Task> responseObserver)
public void runTask(RunTaskRequest request, 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 or
is PAUSED.
This command is meant to be used for manual debugging. For
example, 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 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 will be reset to the time that
RunTask was called plus the retry delay specified
in the queue's RetryConfig.
RunTask returns
NOT_FOUND when it is called on a
task that has already succeeded or permanently failed.
| Parameters |
|---|
| Name | Description |
request | RunTaskRequest
|
responseObserver | io.grpc.stub.StreamObserver<Task>
|
setIamPolicy(SetIamPolicyRequest request, StreamObserver<Policy> responseObserver)
public void setIamPolicy(SetIamPolicyRequest request, StreamObserver<Policy> responseObserver)
Sets the access control policy for a 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 permission on the specified
resource parent:
cloudtasks.queues.setIamPolicy
| Parameters |
|---|
| Name | Description |
request | com.google.iam.v1.SetIamPolicyRequest
|
responseObserver | io.grpc.stub.StreamObserver<com.google.iam.v1.Policy>
|
testIamPermissions(TestIamPermissionsRequest request, StreamObserver<TestIamPermissionsResponse> responseObserver)
public void testIamPermissions(TestIamPermissionsRequest request, StreamObserver<TestIamPermissionsResponse> responseObserver)
Returns permissions that a caller has on a Queue.
If the resource does not exist, this will return an empty set of
permissions, not a 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.
| Parameters |
|---|
| Name | Description |
request | com.google.iam.v1.TestIamPermissionsRequest
|
responseObserver | io.grpc.stub.StreamObserver<com.google.iam.v1.TestIamPermissionsResponse>
|
updateQueue(UpdateQueueRequest request, StreamObserver<Queue> responseObserver)
public void updateQueue(UpdateQueueRequest request, 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.
