A subscription resource. If none of push_config, bigquery_config, or cloud_storage_config is set, then the subscriber will pull and ack messages using API methods. At most one of these fields may be set.

Value parameters

ackDeadlineSeconds

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.

bigqueryConfig

If delivery to BigQuery is used with this subscription, this field is used to configure it.

cloudStorageConfig

If delivery to Google Cloud Storage is used with this subscription, this field is used to configure it.

deadLetterPolicy

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.

detached

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.

enableExactlyOnceDelivery

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.

enableMessageOrdering

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.

expirationPolicy

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.

filter

An expression written in the Pub/Sub [filter language](https://cloud.google.com/pubsub/docs/filtering). 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.

labels

See [Creating and managing labels](https://cloud.google.com/pubsub/docs/labels).

messageRetentionDuration

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 7 days or less than 10 minutes.

name

Required. The name of the subscription. It must have the format "projects/{project}/subscriptions/{subscription}". {subscription} must start with a letter, and contain only letters ([A-Za-z]), numbers ([0-9]), dashes (-), underscores (_), periods (.), tildes (~), plus (+) or percent signs (%). It must be between 3 and 255 characters in length, and it must not start with "goog".

pushConfig

If push delivery is used with this subscription, this field is used to configure it.

retainAckedMessages

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.

retryPolicy

A policy that specifies how Pub/Sub retries message delivery for this subscription. If not set, the default retry policy is applied. This generally implies that messages will be retried as soon as possible for healthy subscribers. RetryPolicy will be triggered on NACKs or acknowledgement deadline exceeded events for a given message.

state

Output only. An output-only field indicating whether or not the subscription can receive messages.

topic

Required. The name of the topic from which this subscription is receiving messages. Format is projects/{project}/topics/{topic}. The value of this field will be _deleted-topic_ if the topic has been deleted.

topicMessageRetentionDuration

Output only. Indicates the minimum duration for which a message is retained after it is published to the subscription's topic. 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.
