-     public class SimpleDBResponseMetadata
      extends ResponseMetadata

  Extension of `ResponseMetadata` with Amazon SimpleDB specific data. In addition to the standard AWS request ID contained in all services' response metadata, Amazon SimpleDB also includes information on how much compute capacity, or box usage, was used to process your request.

  SimpleDB box usage is useful when looking at how different queries perform on your data. You can use that information to tune your queries, and reduce your monthly SimpleDB usage charges.
