Batching

Each HTTP connection that your client makes results in overhead. To reduce overhead, you can batch multiple API calls together into a single HTTP request.

The main classes of interest are BatchRequest and JsonBatchCallback. The following example shows how to use these classes with service-specific generated libraries:

JsonBatchCallback<Calendar> callback = new JsonBatchCallback<Calendar>() {

  public void onSuccess(Calendar calendar, HttpHeaders responseHeaders) {
    printCalendar(calendar);
    addedCalendarsUsingBatch.add(calendar);
  }

  public void onFailure(GoogleJsonError e, HttpHeaders responseHeaders) {
    System.out.println("Error Message: " + e.getMessage());
  }
};

...

Calendar client = Calendar.builder(transport, jsonFactory, credential)
  .setApplicationName("BatchExample/1.0").build();
BatchRequest batch = client.batch();

Calendar entry1 = new Calendar().setSummary("Calendar for Testing 1");
client.calendars().insert(entry1).queue(batch, callback);

Calendar entry2 = new Calendar().setSummary("Calendar for Testing 2");
client.calendars().insert(entry2).queue(batch, callback);

batch.execute();
