  custom role. For some types of Google Cloud resources, a `binding` can also
  specify a `condition`, which is a logical expression that allows access to a

      principals; up to 250 of these principals can be Google groups. Each
      occurrence of a principal counts towards these limits. For example, if
      the `bindings` grant 50 different roles to `user:alice@example.com`, and
      not to any other principal, then you can add another 1,450 principals to
      the `bindings` in the `Policy`.
    etag: `etag` is used for optimistic concurrency control as a way to help
      prevent simultaneous updates of a policy from overwriting each other. It
      is strongly suggested that systems make use of the `etag` in the read-
      modify-write cycle to perform policy updates in order to avoid race
      conditions: An `etag` is returned in the response to `getIamPolicy`, and
      systems are expected to put that etag in the request to `setIamPolicy`
      to ensure that their change will be applied to the same version of the
      policy. **Important:** If you use IAM Conditions, you must include the
      `etag` field whenever you call `setIamPolicy`. If you omit this field,
      then IAM allows you to overwrite a version `3` policy with a version `1`
      policy, and all of the conditions in the version `3` policy are lost.
    version: Specifies the format of the policy. Valid values are `0`, `1`,
      and `3`. Requests that specify an invalid value are rejected. Any
      operation that affects conditional role bindings must specify version
      `3`. This requirement applies to the following operations: * Getting a
      policy that includes a conditional role binding * Adding a conditional
      role binding to a policy * Changing a conditional role binding in a
      policy * Removing any role binding, with or without a condition, from a
      policy that includes conditions **Important:** If you use IAM
      Conditions, you must include the `etag` field whenever you call
      `setIamPolicy`. If you omit this field, then IAM allows you to overwrite
      a version `3` policy with a version `1` policy, and all of the
      conditions in the version `3` policy are lost. If a policy does not
      include any conditions, operations on that policy may specify any valid
      version or leave the field unset. To learn which resources support
      conditions in their IAM policies, see the [IAM
      documentation](https://cloud.google.com/iam/help/conditions/resource-
      policies).

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

  Messages:
    LabelsValue: Optional. See [Creating and managing
      labels](https://cloud.google.com/pubsub/docs/labels).
    TagsValue: Optional. Input only. Immutable. Tag keys/values directly bound
      to this resource. For example: "123/environment": "production",
      "123/costCenter": "marketing"

  Fields:
    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.
    analyticsHubSubscriptionInfo: Output only. Information about the
      associated Analytics Hub subscription. Only set if the subscritpion is
      created by Analytics Hub.
    bigqueryConfig: Optional. If delivery to BigQuery is used with this
      subscription, this field is used to configure it.
    cloudStorageConfig: Optional. If delivery to Google Cloud Storage is used
      with this subscription, this field is used to configure it.
    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.
    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 acknowledgment 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: 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.
    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.
    filter: Optional. An expression written in the Pub/Sub [filter
      language](https://cloud.google.com/pubsub/docs/filtering). 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: Optional. See [Creating and managing
      labels](https://cloud.google.com/pubsub/docs/labels).
    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.
    messageTransforms: Optional. Transforms to be applied to messages before
      they are delivered to subscribers. Transforms are applied in the order
      specified.
    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"`.
    pubsubExportConfig: Optional. If delivery to Pub/Sub is used with this
      subscription, this field is used to configure it.
    pubsubliteExportConfig: Optional. If delivery to Pub/Sub Lite is used with
      this subscription, this field is used to configure it.
    pushConfig: Optional. If push delivery is used with this subscription,
      this field is used to configure it.
    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.
    retryPolicy: 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 acknowledgment deadline exceeded events for a given message.
    state: Output only. An output-only field indicating whether or not the
      subscription can receive messages.
    tags: Optional. Input only. Immutable. Tag keys/values directly bound to
      this resource. For example: "123/environment": "production",
      "123/costCenter": "marketing"
    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`
