 /**
  * Represents the batching settings to use for an API method that is capable of batching.

+ * <p>By default the settings are configured to <b>not</b> use batching (i.e. the batch size
+ * threshold is 1). This is the safest default behavior, which has meaning in all possible

  * <p>Warning: With the wrong settings, it is possible to cause long periods of dead waiting time.

  * <p>When batching is turned on for an API method, a call to that method will result in the request
