> 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
