gatherNodes requires single value fields in the tuples. In certain
scenarios the cartesianProduct streaming expression can be used to explode
a multi-value field into a single field stream. But in the scenario you

Use large batches and fetch instead of hashjoin and lots of parallel

Grouping I believe does not require this is some scenarios.

Either of those cases would be the typical uses of these features.
