Instance Attribute Details

#dead_letter_topic ⇒ String

Optional. The name of the topic to which dead letter messages should be published. Format is projects/project/topics/topic`.The Pub/Sub service account associated with the enclosing subscription's parent project (i.e., service-project_number@gcp-sa-pubsub.iam.gserviceaccount.com) must have permission to Publish() to this topic. The operation will fail if the topic does not exist. Users should ensure that there is a subscription attached to this topic since messages published to a topic with no subscriptions are lost.

#max_delivery_attempts ⇒ Fixnum

Optional. The maximum number of delivery attempts for any message. The value must be between 5 and 100. The number of delivery attempts is defined as 1 + ( the sum of number of NACKs and number of times the acknowledgement deadline has been exceeded for the message). A NACK is any call to ModifyAckDeadline with a 0 deadline. Note that client libraries may automatically extend ack_deadlines. This field will be honored on a best effort basis. If this parameter is 0, a default value of 5 is used. Corresponds to the JSON property maxDeliveryAttempts

Returns:

  • (Fixnum)
