Class DeadLetterPolicy (1.117.0)

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
TypeDescription
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 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
TypeDescription
ByteString

The bytes for deadLetterTopic.

getDefaultInstanceForType()

public DeadLetterPolicy getDefaultInstanceForType()
Returns
TypeDescription
DeadLetterPolicy

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;

Returns
TypeDescription
int

The maxDeliveryAttempts.
