Attributes
| Name | Description |
| subscription |
str
Required. The subscription from which messages should be pulled. Format is ``projects/{project}/subscriptions/{sub}``. |
| return_immediately |
bool
Optional. If this field set to true, the system will respond immediately even if it there are no messages available to return in the ``Pull`` response. Otherwise, the system may wait (for a bounded amount of time) until at least one message is available, rather than returning no messages. Warning: setting this field to ``true`` is discouraged because it adversely impacts the performance of ``Pull`` operations. We recommend that users do not set this field. |
| max_messages |
int
Required. The maximum number of messages to return for this request. Must be a positive integer. The Pub/Sub system may return fewer than the number specified. |
