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 patch projects (response)
• subscriptions create projects (request|response)
• subscriptions get projects (response)

Fields

topic: Option<String>

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.

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.

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.

name: Option<String>

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".

ack_deadline_seconds: Option<i32>

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 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.

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.
