    Description

      When you overload DDB, you get error messages warning of throttling, as documented by AWS

      Reduce load on DDB by doing a table lookup before the create, then, in table create/delete operations and in get/put actions, recognise the error codes and retry using an appropriate retry policy (exponential backoff + ultimate failure)
