      Description

      Currently all the Streaming Expression such as rollups, intersections, fetch etc, work on single value fields. The cartesian expression would create a stream of tuples from a single tuple with a multi-value field. This would allow multi-valued fields to be operated on by the wider library of Streaming Expression.

      For example a single tuple with a multi-valued field:

      id: 1
      author: [Jim, Jack, Steve]

      Would be transformed in the following three tuples:

      id:1
      author:Jim

      id:1
      author:Jack

      id:1
      author:Steve
