getAckDeadlineSeconds()

public int getAckDeadlineSeconds()

The approximate amount of time (on a best-effort basis) Pub/Sub waits for the subscriber to acknowledge receipt before resending the message. In the interval after the message is delivered and before it is acknowledged, it is considered to be <i>outstanding</i>. During that time period, the message will not be redelivered (on a best-effort basis). For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call ModifyAckDeadline with the corresponding ack_id if using non-streaming pull or send the ack_id in a StreamingModifyAckDeadlineRequest if using streaming pull. The minimum custom deadline you can specify is 10 seconds. The maximum custom deadline you can specify is 600 seconds (10 minutes). If this parameter is 0, a default value of 10 seconds is used. For push delivery, this value is also used to set the request timeout for the call to the push endpoint. If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message.

int32 ack_deadline_seconds = 5;

Returns
TypeDescription
int

The ackDeadlineSeconds.

getDeadLetterPolicy()

public DeadLetterPolicy getDeadLetterPolicy()

A policy that specifies the conditions for dead lettering messages in this subscription. If dead_letter_policy is not set, dead lettering is disabled. The Cloud Pub/Sub service account associated with this subscriptions's parent project (i.e., service-{project_number}@gcp-sa-pubsub.iam.gserviceaccount.com) must have permission to Acknowledge() messages on this subscription.

.google.pubsub.v1.DeadLetterPolicy dead_letter_policy = 13;

Returns
TypeDescription
DeadLetterPolicy

The deadLetterPolicy.

getDeadLetterPolicyOrBuilder()

public DeadLetterPolicyOrBuilder getDeadLetterPolicyOrBuilder()

A policy that specifies the conditions for dead lettering messages in this subscription. If dead_letter_policy is not set, dead lettering is disabled. The Cloud Pub/Sub service account associated with this subscriptions's parent project (i.e., service-{project_number}@gcp-sa-pubsub.iam.gserviceaccount.com) must have permission to Acknowledge() messages on this subscription.

.google.pubsub.v1.DeadLetterPolicy dead_letter_policy = 13;

Returns
TypeDescription
DeadLetterPolicyOrBuilder

getDefaultInstanceForType()

public Subscription getDefaultInstanceForType()
Returns
TypeDescription
Subscription

getDetached()

public boolean getDetached()

Indicates whether the subscription is detached from its topic. Detached subscriptions don't receive messages from their topic and don't retain any backlog. Pull and StreamingPull requests will return FAILED_PRECONDITION. If the subscription is a push subscription, pushes to the endpoint will not be made.

bool detached = 15;

Returns
TypeDescription
boolean

The detached.

getEnableExactlyOnceDelivery()

public boolean getEnableExactlyOnceDelivery()

If true, Pub/Sub provides the following guarantees for the delivery of a message with a given value of message_id on this subscription:

  • The message sent to a subscriber is guaranteed not to be resent before the message's acknowledgement deadline expires.
  • An acknowledged message will not be resent to a subscriber. Note that subscribers may still receive multiple copies of a message when enable_exactly_once_delivery is true if the message was published multiple times by a publisher client. These copies are considered distinct by Pub/Sub and have distinct message_id values.

bool enable_exactly_once_delivery = 16;

Returns
TypeDescription
boolean

The enableExactlyOnceDelivery.

getEnableMessageOrdering()

public boolean getEnableMessageOrdering()

If true, messages published with the same ordering_key in PubsubMessage will be delivered to the subscribers in the order in which they are received by the Pub/Sub system. Otherwise, they may be delivered in any order.

bool enable_message_ordering = 10;

Returns
TypeDescription
boolean

The enableMessageOrdering.

getExpirationPolicy()

public ExpirationPolicy getExpirationPolicy()

A policy that specifies the conditions for this subscription's expiration. A subscription is considered active as long as any connected subscriber is successfully consuming messages from the subscription or is issuing operations on the subscription. If expiration_policy is not set, a default policy with ttl of 31 days will be used. The minimum allowed value for expiration_policy.ttl is 1 day.

.google.pubsub.v1.ExpirationPolicy expiration_policy = 11;

Returns
TypeDescription
ExpirationPolicy

The expirationPolicy.

getExpirationPolicyOrBuilder()

public ExpirationPolicyOrBuilder getExpirationPolicyOrBuilder()

A policy that specifies the conditions for this subscription's expiration. A subscription is considered active as long as any connected subscriber is successfully consuming messages from the subscription or is issuing operations on the subscription.

getFilter()
