            # 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::Datastream::V1::Datastream::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.
            #
            # @example
            #
            #   # Modify the global config, setting the timeout for
            #   # list_connection_profiles to 20 seconds,
