> There should be one span for each "read batch" and one scan for each "read file".  The batch spans should be children of the file span.
> If possible it would be nice if the "read file" spans were children of the exec plan when the scanner is being used as a source node.  I'm not sure if this is doable though since the scanner is often used outside the exec plan.
