DESCRIPTION
    Updates an existing Cloud Pub/Sub subscription.

POSITIONAL ARGUMENTS
     Subscription resource - Name of the subscription to update. This
     represents a Cloud resource. (NOTE) Some attributes are not given
     arguments in this group but can be set in other ways. To set the project
     attribute:
      ◆ provide the argument subscription on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.

       SUBSCRIPTION
          ID of the subscription or fully qualified identifier for the
          subscription. To set the subscription attribute:
          ▸ provide the argument subscription on the command line.

FLAGS
     --ack-deadline=ACK_DEADLINE
        The number of seconds the system will wait for a subscriber to
        acknowledge receiving a message before re-attempting delivery.

     --expiration-period=EXPIRATION_PERIOD
        The subscription will expire if it is inactive for the given period.
        Valid values are strings of the form INTEGER[UNIT], where UNIT is one
        of "s", "m", "h", and "d" for seconds, minutes, hours, and days,
        respectively. If the unit is omitted, seconds is assumed. This flag
        additionally accepts the special value "never" to indicate that the
        subscription will never expire.

     --message-retention-duration=MESSAGE_RETENTION_DURATION
        How long to retain unacknowledged messages in the subscription's
        backlog, from the moment a message is published. If
        --retain-acked-messages is true, this also configures the retention of
        acknowledged messages. Specify "default" to use the default value.
        Valid values are strings of the form INTEGER[UNIT], where UNIT is one
        of "s", "m", "h", and "d" for seconds, minutes, hours, and days,
        respectively. If the unit is omitted, seconds is assumed.

     --push-auth-service-account=SERVICE_ACCOUNT_EMAIL
        Service account email used as the identity for the generated Open ID
        Connect token for authenticated push.

     --push-auth-token-audience=OPTIONAL_AUDIENCE_OVERRIDE
        Audience used in the generated Open ID Connect token for authenticated
        push. If not specified, it will be set to the push-endpoint.

     --push-endpoint=PUSH_ENDPOINT
        A URL to use as the endpoint for this subscription. This will also
        automatically set the subscription type to PUSH.

     --retain-acked-messages
        Whether or not to retain acknowledged messages. If true, messages are
        not expunged from the subscription's backlog until they fall out of the
        --message-retention-duration window. Acknowledged messages are not
        retained by default.

     --update-labels=[KEY=VALUE,...]
        List of label KEY=VALUE pairs to update. If a label exists, its value
        is modified. Otherwise, a new label is created.

        Keys must start with a lowercase character and contain only hyphens
        (-), underscores (_), lowercase characters, and numbers. Values must
        contain only hyphens (-), underscores (_), lowercase characters, and

       --clear-bigquery-config
          If set, clear the BigQuery config from the subscription.

       with the enclosing subscription's parent project (i.e.,
       service-{project_number}@gcp-sa-pubsub.iam.gserviceaccount.com) must
       have permission to write to this BigQuery table.

         --bigquery-table=BIGQUERY_TABLE
            A BigQuery table of the form {project}:{dataset_name}.{table_name}
            to which to write messages for this subscription.

            This flag must be specified if any of the other arguments in this
            group are specified.

         --drop-unknown-fields
            When --use-topic-schema is set, whether or not to ignore fields in
            the topic schema that do not appear in the BigQuery schema. If
            false, then the BigQuery schema must contain all fields that are
            also present in the topic schema.

         --use-topic-schema
            Whether or not to use the schema for the subscription's topic (if
            it exists) when writing messages to BigQuery.

         --write-metadata
            Whether or not to write message metadata including message ID,

       with the enclosing subscription's parent project (i.e.,
       service-{project_number}@gcp-sa-pubsub.iam.gserviceaccount.com) must
       have permission to Publish() to this topic and Acknowledge() messages on
       this subscription.

         --max-delivery-attempts=MAX_DELIVERY_ATTEMPTS
            Maximum number of delivery attempts for any message. The value must
            be between 5 and 100. Defaults to 5. --dead-letter-topic must also
            be specified.

         Dead letter topic resource - Name of the topic to publish dead letter
         messages to. The arguments in this group can be used to specify the

           --dead-letter-topic=DEAD_LETTER_TOPIC
              ID of the dead-letter-topic or fully qualified identifier for the
              dead-letter-topic. To set the topic attribute:
              ◇ provide the argument --dead-letter-topic on the command line.

              This flag must be specified if any of the other arguments in this
              group are specified.

           --dead-letter-topic-project=DEAD_LETTER_TOPIC_PROJECT
              Project ID of the Google Cloud project for the dead-letter-topic.

                command line;
              ◇ provide the argument --project on the command line;
              ◇ set the property core/project.

     At most one of these can be specified:

       --clear-labels
          Remove all labels. If --update-labels is also specified then
          --clear-labels is applied first.

          For example, to remove all labels:

              $ gcloud pubsub subscriptions update --clear-labels

          To remove all existing labels and create two new labels, foo and baz:

              $ gcloud pubsub subscriptions update --clear-labels \
                --update-labels foo=bar,baz=qux

       --remove-labels=[KEY,...]
          List of label keys to remove. If a label does not exist it is
          silently ignored. If --update-labels is also specified then
          --update-labels is applied first.

     At most one of these can be specified:

       --clear-retry-policy
          If set, clear the retry policy from the subscription.

       Retry Policy Options. Retry policy specifies how Cloud Pub/Sub retries

            message. Value should be between 0 and 600 seconds. Defaults to 10
            seconds. Valid values are strings of the form INTEGER[UNIT], where
            UNIT is one of "s", "m", "h", and "d" for seconds, minutes, hours,
            and days, respectively. If the unit is omitted, seconds is assumed.

         --min-retry-delay=MIN_RETRY_DELAY
            The minimum delay between consecutive deliveries of a given
            message. Value should be between 0 and 600 seconds. Defaults to 10
            seconds. Valid values are strings of the form INTEGER[UNIT], where
            UNIT is one of "s", "m", "h", and "d" for seconds, minutes, hours,
