Overview

A subscription resource. If none of push_config, bigquery_config, or cloud_storage_config is set, then the subscriber will pull and ack messages using API methods. At most one of these fields may be set.

#ack_deadline_seconds ⇒ ::Integer

Returns Optional. The approximate amount of time (on a best-effort basis) Pub/Sub waits for the subscriber to acknowledge receipt before resending the message. In the interval after the message is delivered and before it is acknowledged, it is considered to be outstanding. During that time period, the message will not be redelivered (on a best-effort basis).

For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call ModifyAckDeadline with the corresponding ack_id if using non-streaming pull or send the ack_id in a StreamingModifyAckDeadlineRequest if using streaming pull. The minimum custom deadline you can specify is 10 seconds. The maximum custom deadline you can specify is 600 seconds (10 minutes). If this parameter is 0, a default value of 10 seconds is used.

For push delivery, this value is also used to set the request timeout for the call to the push endpoint.

If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message.

#enable_exactly_once_delivery ⇒ ::Boolean

Returns Optional. If true, Pub/Sub provides the following guarantees for the delivery of a message with a given value of message_id on this subscription:

  • An acknowledged message will not be resent to a subscriber.

Note that subscribers may still receive multiple copies of a message when enable_exactly_once_delivery is true if the message was published multiple times by a publisher client. These copies are considered distinct by Pub/Sub and have distinct message_id values.

This must be true if you would like to Seek to a timestamp in the past to replay previously-acknowledged messages.

Returns Optional. A policy that specifies how Pub/Sub retries message delivery for this subscription.

If not set, the default retry policy is applied. This generally implies that messages will be retried as soon as possible for healthy subscribers. RetryPolicy will be triggered on NACKs or acknowledgement deadline exceeded events for a given message.
