Class DeadLetterPolicy.Builder (1.131.0)

public static final class DeadLetterPolicy.Builder extends GeneratedMessageV3.Builder<DeadLetterPolicy.Builder> implements DeadLetterPolicyOrBuilder

clearDeadLetterTopic()

public DeadLetterPolicy.Builder clearDeadLetterTopic()

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.

clearMaxDeliveryAttempts()

public DeadLetterPolicy.Builder clearMaxDeliveryAttempts()

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.
