Kiyan Ahmadizadeh created CRUNCH-58:

             Summary: Implement PObject in Crunch/Scrunch
                 Key: CRUNCH-58
             Project: Crunch
          Issue Type: New Feature
    Affects Versions: 0.3.0
            Reporter: Kiyan Ahmadizadeh
            Assignee: Kiyan Ahmadizadeh

FlumeJava has the concept of a PObject<T>, a container for a singleton of type T.  It
is meant represent the result of a distributed computation that yields a singleton value (for
example max, min, and length methods on PCollection<T>).  Generally speaking, the result
of any computation that combines/reduces a PCollection into a singleton value could be represented
by a PObject.  

Like PCollection, a PObject defers distributed computation until its value is actually used.
