[Enhancement]: Send bulk push notifications

[archita13]

Background story

I need to use pinpoint for sending push notifications in batches, instead of 1:1. The public documentation provides example (https://docs.aws.amazon.com/pinpoint/latest/developerguide/send-messages-sms.html) of using the SendMessages API to send a single SMS message. I can tweak it to send a single push notification but I am wondering how to tweak it further to send multiple push notifications at once.

The API documentation (https://docs.aws.amazon.com/pinpoint/latest/apireference/apps-application-id-messages.html) also mentions that You can send a direct message to as many as 100 recipients. , but there is no example of how to do this. A code example in java would really help!

What does this example accomplish?

Java code to use AWS pinpoint SDK to send push notifications to X different customers at once.

Which AWS service(s)?

Pinpoint

Are there existing code examples to leverage?

Code reference to send a single message:

` public static void sendSMSMessage(PinpointClient pinpoint, String message, String appId, String originationNumber, String destinationNumber) {

try {

    Map<String, AddressConfiguration> addressMap =
            new HashMap<String, AddressConfiguration>();

    AddressConfiguration addConfig = AddressConfiguration.builder()
            .channelType(ChannelType.SMS)
            .build();

    addressMap.put(destinationNumber, addConfig);

    SMSMessage smsMessage = SMSMessage.builder()
            .body(message)
            .messageType(messageType)
            .originationNumber(originationNumber)
            .senderId(senderId)
            .keyword(registeredKeyword)
            .build();

    // Create a DirectMessageConfiguration object
    DirectMessageConfiguration direct = DirectMessageConfiguration.builder()
            .smsMessage(smsMessage)
            .build();

    MessageRequest msgReq = MessageRequest.builder()
            .addresses(addressMap)
            .messageConfiguration(direct)
            .build();

    // create a  SendMessagesRequest object
    SendMessagesRequest request = SendMessagesRequest.builder()
            .applicationId(appId)
            .messageRequest(msgReq)
            .build();

    SendMessagesResponse response= pinpoint.sendMessages(request);

    MessageResponse msg1 = response.messageResponse();
    Map map1 = msg1.result();

    //Write out the result of sendMessage
    map1.forEach((k, v) -> System.out.println((k + ":" + v)));

} catch (PinpointException e) {
    System.err.println(e.awsErrorDetails().errorMessage());
    System.exit(1);
}

}`

Do you have any reference code?
