Struct google_pubsub1::api::Subscription [−][src]
A subscription resource.
Activities
This type is used in activities, which are methods you may call on this type or where this type is involved in. The list links the activity name, along with information about where it is used (one of request and response).
- subscriptions create projects (request|response)
- subscriptions get projects (response)
- subscriptions patch projects (response)
Fields
ack_deadline_seconds: Option<i32>
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.
dead_letter_policy: Option<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: Option<bool>
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.
enable_message_ordering: Option<bool>
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.
expiration_policy: Option<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.
filter: Option<String>
An expression written in the Pub/Sub filter language. If non-empty, then only PubsubMessage
s whose attributes
field matches the filter are delivered on this subscription. If empty, then no messages are filtered out.
labels: Option<HashMap<String, String>>
See Creating and managing labels.
message_retention_duration: Option<String>
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: Option<String>
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"
.
push_config: Option<PushConfig>
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.
retain_acked_messages: Option<bool>
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.
retry_policy: Option<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.
topic: Option<String>
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.
