            #     returned may be fewer.
            #
            #     For example, this may be set to one fewer than the number of parallel
            #     queries to be run, or in running a data pipeline job, one fewer than the
            #     number of workers or compute instances available.

            #     The `next_page_token` value returned from a previous call to
            #     PartitionQuery that may be used to get an additional set of results.
            #     There are no ordering guarantees between sets of results. Thus, using
            #     multiple sets of results will require merging the different result sets.
            #
            #     For example, two subsequent calls using a page_token may return:
            #
            #      * cursor B, cursor M, cursor Q
            #      * cursor A, cursor U, cursor W
            #
            #     To obtain a complete result set ordered with respect to the results of the
            #     query supplied to PartitionQuery, the results sets should be merged:
            #     cursor A, cursor B, cursor M, cursor Q, cursor U, cursor W
            #   @param page_size [::Integer]
            #     The maximum number of partitions to return in this call, subject to
            #     `partition_count`.
            #
            #     For example, if `partition_count` = 10 and `page_size` = 8, the first call
            #     to PartitionQuery will return up to 8 partitions and a `next_page_token`
            #     if more results exist. A second call to PartitionQuery will return up to
            #     2 partitions, to complete the total of 10 specified in `partition_count`.

            #
            # This class represents the configuration for Firestore,
            # providing control over timeouts, retry behavior, logging, transport
            # parameters, and other low-level controls. Certain parameters can also be
            # applied individually to specific RPCs. See
            # {::Google::Cloud::Firestore::V1::Firestore::Client::Configuration::Rpcs}
            # for a list of RPCs that can be configured independently.
            #
            # Configuration can be applied globally to all clients, or to a single client
            # on construction.
            #
            # # Examples
            #
            # To modify the global config, setting the timeout for get_document
            # to 20 seconds, and all remaining timeouts to 10 seconds:
            #
            #     ::Google::Cloud::Firestore::V1::Firestore::Client.configure do |config|
            #       config.timeout = 10.0
            #       config.rpcs.get_document.timeout = 20.0
            #     end
            #
            # To apply the above configuration only to a new client:
            #
            #     client = ::Google::Cloud::Firestore::V1::Firestore::Client.new do |config|
            #       config.timeout = 10.0
