      Description

      And another, from Selina Zhang and Chris Drome. (YHIVE-927)

      When a mapper needs to process multiple ORC files, it might land up having use essentially the same SearchArgument over several files. It would be good not to have to deserialize from string, over and over again. Caching the object against the string-form should speed things up.
