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.

Overrides
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
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 |
ByteString | The bytes for deadLetterTopic.

getDefaultInstanceForType()
public DeadLetterPolicy getDefaultInstanceForType()
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 |
|---|
| Type | Description |
int | The maxDeliveryAttempts.
