public final class DeadLetterPolicy extends 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;
Returns | |
---|---|
Type | Description |
String | The deadLetterTopic. |
getDeadLetterTopicBytes()
public 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

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.
