Properties

AckDeadlineSeconds

Optional. 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 outstanding. 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.

Declaration
[JsonProperty("ackDeadlineSeconds")]
public virtual int? AckDeadlineSeconds { get; set; }
Property Value
Type Description
int?

DeadLetterPolicy

Optional. 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 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.

Detached

Optional. 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.

Declaration
[JsonProperty("detached")]
public virtual bool? Detached { get; set; }
Property Value
Type Description
bool?

ETag

The ETag of the item.

Declaration
public virtual string ETag { get; set; }
Property Value
Type Description
string

EnableExactlyOnceDelivery

Optional. 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.

Declaration
[JsonProperty("enableExactlyOnceDelivery")]
public virtual bool? EnableExactlyOnceDelivery { get; set; }
Property Value
Type Description
bool?

EnableMessageOrdering

Optional. 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.

Declaration
[JsonProperty("enableMessageOrdering")]
public virtual bool? EnableMessageOrdering { get; set; }
Property Value
Type Description
bool?

ExpirationPolicy

Optional. 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. If expiration_policy is set, but expiration_policy.ttl is not set, the subscription never expires.

Declaration
[JsonProperty("expirationPolicy")]
public virtual ExpirationPolicy ExpirationPolicy { get; set; }
Property Value
Type Description
ExpirationPolicy

Filter

Optional. An expression written in the Pub/Sub filter language. If non-empty, then only PubsubMessages whose attributes field matches the filter are delivered on this subscription. If empty, then no messages are filtered out.

Declaration
[JsonProperty("filter")]
public virtual string Filter { get; set; }
Property Value
Type Description
string

Labels

Optional. See Creating and managing labels.

Declaration
[JsonProperty("labels")]
public virtual IDictionary<string, string> Labels { get; set; }
Property Value
Type Description

MessageRetentionDuration

Optional. How long to retain unacknowledged messages in the subscription's backlog, from the moment a message is published. If retain_acked_messages is true, then this also configures the retention of acknowledged messages, and thus configures how far back in time a Seek can be done. Defaults to 7 days. Cannot be more than 31 days or less than 10 minutes.

Declaration
[JsonProperty("messageRetentionDuration")]
public virtual object MessageRetentionDuration { get; set; }
Property Value

Declaration
[JsonProperty("pushConfig")]
public virtual PushConfig PushConfig { get; set; }
Property Value
Type Description

RetainAckedMessages

Optional. Indicates whether to retain acknowledged messages. If true, then messages are not expunged from the subscription's backlog, even if they are acknowledged, until they fall out of the message_retention_duration window. This must be true if you would like to [Seek to a timestamp] (https://cloud.google.com/pubsub/docs/replay-overview#seek_to_a_time) in the past to replay previously-acknowledged messages.

Declaration
[JsonProperty("retainAckedMessages")]
public virtual bool? RetainAckedMessages { get; set; }
Property Value
Type Description
bool?

RetryPolicy

Optional. A policy that specifies how Pub/Sub retries message delivery for this subscription. If not set, the default retry policy is applied.

Declaration
[JsonProperty("retryPolicy")]
public virtual RetryPolicy RetryPolicy { get; set; }
Property Value

If this field is set, messages published to the subscription's topic in the last topic_message_retention_duration are always available to subscribers. See the message_retention_duration field in Topic. This field is set only in responses from the server; it is ignored if it is set in any requests.

Declaration
[JsonProperty("topicMessageRetentionDuration")]
public virtual object TopicMessageRetentionDuration { get; set; }
Property Value
Type Description
