Instance Attribute Details

#ack_deadline_seconds ⇒ Integer

Returns This value is the maximum time after a subscriber receives a message before the subscriber should acknowledge the message. After message delivery but before the ack deadline expires and before the message is acknowledged, it is an outstanding message and will not be delivered again during that time (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 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.

Returns:

#message_retention_duration ⇒ Google::Protobuf::Duration

Returns How long to retain unacknowledged messages in the subscription's backlog, from the moment a message is published.

Cannot be more than 7 days or less than 10 minutes.
