Binary data handling changes

In version 1, binary data was handled using ByteBuffer objects directly. In version 2, the SDK uses SdkBytes objects that provide a more convenient and type-safe way to work with binary data.

You can convert SdkBytes to ByteBuffer automatically using the migration tool, or you can convert them manually by calling asByteBuffer() on the returned SdkBytes object.

Example - Get binary data from a message attribute in version 1

// Get binary data from a message attribute
MessageAttributeValue messageAttributeValue = new MessageAttributeValue();
ByteBuffer binaryValue = messageAttributeValue.getBinaryValue();
String binaryString = new String(messageAttributeValue.getBinaryValue().array());

Example - Get binary data from a message attribute in version 2

// Get binary data from a message attribute
MessageAttributeValue messageAttributeValue = MessageAttributeValue.builder().build();
ByteBuffer binaryValue = messageAttributeValue.binaryValue().asByteBuffer();
String binaryString = new String(messageAttributeValue.binaryValue().asByteBuffer().array());
