            Optional. The maximum number of sinks in each page of results from
            this request. Non-positive values are ignored. Defaults to a
            sensible value set by the API.

        :type page_token: str
        :param page_token:
            Optional. If present, return the next batch of sinks, using the
            value, which must correspond to the ``nextPageToken`` value
            returned in the previous response.  Deprecated: use the ``pages``
            property of the returned iterator instead of manually passing the
            token.
