Cloud Pub/Sub V1 API - Class Google::Cloud::PubSub::V1::DeadLetterPolicy (v0.18.1)

Reference documentation and code samples for the Cloud Pub/Sub V1 API class Google::Cloud::PubSub::V1::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.

Methods

#dead_letter_topic

def dead_letter_topic() -> ::String
Returns
  • (::String) — 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.

#dead_letter_topic=

def dead_letter_topic=(value) -> ::String
Parameter
  • value (::String) — 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.

#max_delivery_attempts

def max_delivery_attempts() -> ::Integer
Returns
  • (::Integer) — 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.
