pub struct LeaseTasksRequest {
    pub parent: String,

    pub lease_duration: Option<Duration>,
    pub response_view: i32,
    pub filter: String,
}

Request message for leasing tasks using [LeaseTasks][google.cloud.tasks.v2beta2.CloudTasks.LeaseTasks].

Fields

parent: String

Required. The queue name. For example: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID

max_tasks: i32

The maximum number of tasks to lease.

The system will make a best effort to return as close to as max_tasks as possible.

The largest that max_tasks can be is 1000.

The maximum total size of a [lease tasks response][google.cloud.tasks.v2beta2.LeaseTasksResponse] is 32 MB. If the sum of all task sizes requested reaches this limit, fewer tasks than requested are returned.

lease_duration: Option<Duration>

Required. The duration of the lease.

Each task returned in the [response][google.cloud.tasks.v2beta2.LeaseTasksResponse] will have its [schedule_time][google.cloud.tasks.v2beta2.Task.schedule_time] set to the current time plus the lease_duration. The task is leased until its [schedule_time][google.cloud.tasks.v2beta2.Task.schedule_time]; thus, the task will not be returned to another [LeaseTasks][google.cloud.tasks.v2beta2.CloudTasks.LeaseTasks] call before its [schedule_time][google.cloud.tasks.v2beta2.Task.schedule_time].

After the worker has successfully finished the work associated with the task, the worker must call via [AcknowledgeTask][google.cloud.tasks.v2beta2.CloudTasks.AcknowledgeTask] before the [schedule_time][google.cloud.tasks.v2beta2.Task.schedule_time]. Otherwise the task will be returned to a later [LeaseTasks][google.cloud.tasks.v2beta2.CloudTasks.LeaseTasks] call so that another worker can retry it.

The maximum lease duration is 1 week. lease_duration will be truncated to the nearest second.

response_view: i32

The response_view specifies which subset of the [Task][google.cloud.tasks.v2beta2.Task] will be returned.

By default response_view is [BASIC][google.cloud.tasks.v2beta2.Task.View.BASIC]; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains.

Authorization for [FULL][google.cloud.tasks.v2beta2.Task.View.FULL] requires cloudtasks.tasks.fullView Google IAM permission on the [Task][google.cloud.tasks.v2beta2.Task] resource.

filter: String

filter can be used to specify a subset of tasks to lease.

When filter is set to tag=<my-tag> then the [response][google.cloud.tasks.v2beta2.LeaseTasksResponse] will contain only tasks whose [tag][google.cloud.tasks.v2beta2.PullMessage.tag] is equal to <my-tag>. <my-tag> must be less than 500 characters.

When filter is set to tag_function=oldest_tag(), only tasks which have the same tag as the task with the oldest [schedule_time][google.cloud.tasks.v2beta2.Task.schedule_time] will be returned.

Grammar Syntax:

• filter = "tag=" tag | "tag_function=" function

• tag = string

• function = "oldest_tag()"

The oldest_tag() function returns tasks which have the same tag as the oldest task (ordered by schedule time).

SDK compatibility: Although the SDK allows tags to be either string or bytes, only UTF-8 encoded tags can be used in Cloud Tasks. Tag which aren’t UTF-8 encoded can’t be used in the [filter][google.cloud.tasks.v2beta2.LeaseTasksRequest.filter] and the task’s [tag][google.cloud.tasks.v2beta2.PullMessage.tag] will be displayed as empty in Cloud Tasks.
