LeaseTasksRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)Request message for leasing tasks using LeaseTasks.
Attributes |
|
|---|---|
| Name | Description |
parent |
str
Required. The queue name. For example: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID
|
max_tasks |
int
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 |
google.protobuf.duration_pb2.Duration
Required. The duration of the lease. Each task returned in the response will have its schedule_time set to the current time plus the lease_duration. The
task is leased until its
schedule_time;
thus, the task will not be returned to another
LeaseTasks
call before its
schedule_time.
After the worker has successfully finished the work
associated with the task, the worker must call via
AcknowledgeTask
before the
schedule_time.
Otherwise the task will be returned to a later
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 |
google.cloud.tasks_v2beta2.types.Task.View
The response_view specifies which subset of the Task will be returned. By default response_view is 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 requires cloudtasks.tasks.fullView `Google
IAM |
filter |
str
filter can be used to specify a subset of tasks to
lease.
When filter is set to tag= then the
response
will contain only tasks whose
tag is equal
to filter is set to tag_function=oldest_tag(),
only tasks which have the same tag as the task with the
oldest
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
and the task's
tag will be
displayed as empty in Cloud Tasks.
