Fields | |
---|---|
Optional |
This value is the maximum time after a subscriber receives a message before the subscriber should acknowledge the message. After message delivery but before the ack deadline expires and before the message is acknowledged, it is an outstanding message and will not be delivered again during that time (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 subscriptions.modifyAckDeadline with the corresponding ackId if using 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. |
Optional |
If delivery to BigQuery is used with this subscription, this field is used to configure it. Either pushConfig, bigQueryConfig or cloudStorageConfig can be set, but not combined. If all three are empty, then the subscriber will pull and ack messages using API methods. |
Optional |
When true and useTopicSchema is true, any fields that are a part of the topic schema that are not part of the BigQuery table schema are dropped when writing to BigQuery. Otherwise, the schemas must be kept in sync and any messages with extra fields are not written and remain in the subscription's backlog. |
Required* |
The name of the table to which to write data. |
Optional |
Allowed value: string of the format `{{project}}.{{dataset_id}}.{{value}}`, where {{value}} is the `name` field of a `BigQueryTable` resource. |
Optional |
Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names |
Optional |
Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/ |
Optional |
When true, use the topic's schema as the columns to write to in BigQuery, if it exists. |
Optional |
When true, write the subscription name, messageId, publishTime, attributes, and orderingKey to additional columns in the table. The subscription name, messageId, and publishTime fields are put in their own columns while all other message properties (other than data) are written to a JSON object in the attributes column. |
Optional |
If delivery to Cloud Storage is used with this subscription, this field is used to configure it. Either pushConfig, bigQueryConfig or cloudStorageConfig can be set, but not combined. If all three are empty, then the subscriber will pull and ack messages using API methods. |
Optional |
If set, message data will be written to Cloud Storage in Avro format. |
Optional |
When true, write the subscription name, messageId, publishTime, attributes, and orderingKey as additional fields in the output. |
Required* |
User-provided name for the Cloud Storage bucket. The bucket must be created by the user. The bucket name must be without any prefix like "gs://". |
Optional |
Allowed value: The `name` field of a `StorageBucket` resource. |
Optional |
Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names |
Optional |
Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/ |
Optional |
User-provided prefix for Cloud Storage filename. |
Optional |
User-provided suffix for Cloud Storage filename. Must not end in "/". |
Optional |
The maximum bytes that can be written to a Cloud Storage file before a new file is created. Min 1 KB, max 10 GiB. The maxBytes limit may be exceeded in cases where messages are larger than the limit. |
Optional |
The maximum duration that can elapse before a new Cloud Storage file is created. Min 1 minute, max 10 minutes, default 5 minutes. May not exceed the subscription's acknowledgement deadline. A duration in seconds with up to nine fractional digits, ending with 's'. Example: "3.5s". |
Optional |
An output-only field that indicates whether or not the subscription can receive messages. |
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 Cloud Pub/Sub service account associated with this subscription's parent project (i.e., service-{project_number}@gcp-sa-pubsub.iam.gserviceaccount.com) must have permission to Acknowledge() messages on this subscription. |
Optional |
|
Optional |
Allowed value: string of the format `projects/{{project}}/topics/{{value}}`, where {{value}} is the `name` field of a `PubSubTopic` resource. |
Optional |
Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names |
Optional |
Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/ |
Optional |
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. |
Optional |
If 'true', Pub/Sub provides the following guarantees for the delivery of a message with a given value of messageId on this Subscriptions': - 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 messageId values. |
Optional |
Immutable. If 'true', messages published with the same orderingKey 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. |
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 expirationPolicy is not set, a default policy with ttl of 31 days will be used. If it is set but ttl is "", the resource never expires. The minimum allowed value for expirationPolicy.ttl is 1 day. |
Required* |
Specifies the "time-to-live" duration for an associated resource. The resource expires if it is not active for a period of ttl. If ttl is set to "", the associated resource never expires. A duration in seconds with up to nine fractional digits, terminated by 's'. Example - "3.5s". |
Optional |
Immutable. The subscription only delivers the messages that match the filter. Pub/Sub automatically acknowledges the messages that don't match the filter. You can filter messages by their attributes. The maximum length of a filter is 256 bytes. After creating the subscription, you can't modify the filter. |
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 subscriptions.seek can be done. Defaults to 7 days. Cannot be more than 7 days ('"604800s"') or less than 10 minutes ('"600s"'). A duration in seconds with up to nine fractional digits, terminated by 's'. Example: '"600.5s"'. |
Optional |
If push delivery is used with this subscription, this field is used to configure it. An empty pushConfig signifies that the subscriber will pull and ack messages using API methods. |
Optional |
Endpoint configuration attributes. Every endpoint has a set of API supported attributes that can be used to control different aspects of the message delivery. The currently supported attribute is x-goog-version, which you can use to change the format of the pushed message. This attribute indicates the version of the data expected by the endpoint. This controls the shape of the pushed message (i.e., its fields and metadata). The endpoint version is based on the version of the Pub/Sub API. If not present during the subscriptions.create call, it will default to the version of the API used to make such call. If not present during a subscriptions.modifyPushConfig call, its value will not be changed. subscriptions.get calls will always return a valid version, even if the subscription was created without this attribute. The possible values for this attribute are: - v1beta1: uses the push format defined in the v1beta1 Pub/Sub API. - v1 or v1beta2: uses the push format defined in the v1 Pub/Sub API. |
Optional |
When set, the payload to the push endpoint is not wrapped.Sets the 'data' field as the HTTP body for delivery. |
Required* |
When true, writes the Pub/Sub message metadata to
'x-goog-pubsub- |
Optional |
If specified, Pub/Sub will generate and attach an OIDC JWT token as an Authorization header in the HTTP request for every pushed message. |
Optional |
Audience to be used when generating OIDC token. The audience claim identifies the recipients that the JWT is intended for. The audience value is a single case-sensitive string. Having multiple values (array) for the audience field is not supported. More info about the OIDC JWT token audience here: https://tools.ietf.org/html/rfc7519#section-4.1.3 Note: if not specified, the Push endpoint URL will be used. |
Required* |
Service account email to be used for generating the OIDC token. The caller (for subscriptions.create, subscriptions.patch, and subscriptions.modifyPushConfig RPCs) must have the iam.serviceAccounts.actAs permission for the service account. |
Required* |
A URL locating the endpoint to which messages should be pushed. For example, a Webhook endpoint might use "https://example.com/push". |
Optional |
Immutable. Optional. The name of the resource. Used for creation and acquisition. When unset, the value of `metadata.name` is used as the default. |
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 messageRetentionDuration window. |
Optional |
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. |
Optional |
The maximum delay between consecutive deliveries of a given message. Value should be between 0 and 600 seconds. Defaults to 600 seconds. A duration in seconds with up to nine fractional digits, terminated by 's'. Example: "3.5s". |
Optional |
The minimum delay between consecutive deliveries of a given message. Value should be between 0 and 600 seconds. Defaults to 10 seconds. A duration in seconds with up to nine fractional digits, terminated by 's'. Example: "3.5s". |
Required |
Reference to a PubSubTopic. |
Optional |
Allowed value: string of the format `projects/{{project}}/topics/{{value}}`, where {{value}} is the `name` field of a `PubSubTopic` resource. |
Optional |
Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names |
Optional |
Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/ |
