            # on construction.
            #
            # # Examples
            #
            # To modify the global config, setting the timeout for read_rows
            # to 20 seconds, and all remaining timeouts to 10 seconds:
            #
            #     ::Google::Cloud::Bigtable::V2::Bigtable::Client.configure do |config|
            #       config.timeout = 10.0
            #       config.rpcs.read_rows.timeout = 20.0
            #     end
            #
            # To apply the above configuration only to a new client:
            #
            #     client = ::Google::Cloud::Bigtable::V2::Bigtable::Client.new do |config|
            #       config.timeout = 10.0
            #       config.rpcs.read_rows.timeout = 20.0
