Review Comment:
   To be compatible with older versions, you should get the id automatically 
generated by the old version
   ```
   import java.io.ObjectStreamClass;
   
   public class SerialVersionUIDChecker {
       public static void main(String[] args) {
           long serialVersionUID = 
ObjectStreamClass.lookup(AmazonDynamoDBSourceSplit.class).getSerialVersionUID();
           System.out.println("serialVersionUID = " + serialVersionUID);
       }
   }
   
   ```
