Amazon sesThrottling - 超過最大發送速率

Question

按照documentation的說法，如果達到最大發送速率，我會收到錯誤消息。我的最大發送速率是每秒14封電子郵件，並且我試圖發送100封郵件同意書，所有電子郵件都發送給收件人。

所以我不知道爲什麼亞馬遜SES沒有發「信號」抱怨我多餘的或更容易，爲什麼亞馬遜SES沒有提供所有的100封郵件時，它應該只發送14

這裏是我使用的代碼：

List<String> destinations = new ArrayList<>(); //replace with your TO email addresses 

    for (int i = 0; i < 100; i++) { 
     destinations.add("Receiver address"); 
    } 
    int i=0; 
    for (String destination : destinations) { 

     new Thread("" + i){ 
      public void run(){ 
       System.out.println("Thread: " + getName() + " running"); 
       int maxRetries = 10; 
       while(maxRetries-->0) { 
        try { 
         // Create the subject and body of the message. 
         Content subject = new Content().withData("Asunto"); 
         Content textBody = new Content().withData("cuerpo"); 
         Body body = new Body().withText(textBody); 

         // Create a message with the specified subject and body. 
         Message message = new Message().withSubject(subject).withBody(body); 
         Destination destination2 = new Destination().withToAddresses(new String[]{destination}); 
         // Assemble the email. 
         SendEmailRequest request = new SendEmailRequest().withSource("fromnaddres").withDestination(destination2).withMessage(message); 

         //wait for a permit to become available 
         //rateLimiter.acquire(); 

         //call Amazon SES to send the message 
         SendEmailResult result = client.sendEmail(request); 
         System.out.println("sent "+result.getMessageId()); 
         break; 
        } catch (AmazonServiceException e) { 
         //retries only throttling errors 
         System.out.println("hola"); 
         if ("Throttling".equals(e.getErrorCode()) && "Maximum sending rate exceeded.".equals(e.getMessage())) { 
          System.out.println("Maximum send rate exceeded when sending email to "+destination+". " 
            +(maxRetries>1?"Will retry.":"Will not retry.")); 
         } else { 
          System.out.println("Unable to send email to: "+destination+". " +e.toString()); 
          break; 
         } 
        } catch(Exception e) { 
         System.out.println("Unable to send email to: "+destination+". " +e.toString()); 
         break; 
        } 
       } 
      } 
     }.start(); 

     i++; 
    }

亞馬遜SES爲每日消息配額和最大發送速率提供了一些空間或靈活性。他們沒有透露允許的偏差百分比是多少，但你可以通過做一些測試找到答案。
