[jira] [Created] (CRUNCH-175) Add support for in-memory Cartesian products

Josh Wills created CRUNCH-175:
---------------------------------

             Summary: Add support for in-memory Cartesian products
                 Key: CRUNCH-175
                 URL: https://issues.apache.org/jira/browse/CRUNCH-175
             Project: Crunch
          Issue Type: Bug
          Components: Core, MapReduce Patterns
            Reporter: Josh Wills
            Assignee: Josh Wills


Another starter JIRA: it would be great to have a version of the Cartesian product functions in crunch lib that reads one of the datasets into memory on each mapper and created the Cartesian product with the second data set, sort of like the InMemoryJoin pattern, but without any keys.
