class Google::Apis::PubsubV1::DeadLetterPolicy
Dead lettering is done on a best effort basis. The same message might be dead lettered multiple times. If validation on any of the fields fails at subscription creation/updation, the create/update subscription request will fail.
Attributes
The name of the topic to which dead letter messages should be published. Format is `projects/`project`/topics/`topic“.The Cloud 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. Corresponds to the JSON property `deadLetterTopic` @return [String]
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` @return [Fixnum]
