Class DeadLetterPolicy

  • All Implemented Interfaces:
    com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, DeadLetterPolicyOrBuilder, Serializable
    public final class DeadLetterPolicy
extends com.google.protobuf.GeneratedMessageV3
implements DeadLetterPolicyOrBuilder
     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.

      • getDeadLetterTopic

        public String getDeadLetterTopic()
         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.
        string dead_letter_topic = 1;
        Specified by:
        getDeadLetterTopic in interface DeadLetterPolicyOrBuilder
        Returns:
        The deadLetterTopic.

      • getDeadLetterTopicBytes

        public com.google.protobuf.ByteString getDeadLetterTopicBytes()
         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.

        string dead_letter_topic = 1;
        Specified by:
        getDeadLetterTopicBytes in interface DeadLetterPolicyOrBuilder
        Returns:
        The bytes for deadLetterTopic.

      • getMaxDeliveryAttempts

        public int getMaxDeliveryAttempts()
         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.
        int32 max_delivery_attempts = 2;
        Specified by:
        getMaxDeliveryAttempts in interface DeadLetterPolicyOrBuilder
        Returns:
        The maxDeliveryAttempts.
