> Currently, CoGroupByKey creates UnionTables that are Flattened. The Flattened
> output is processed by a GroupByKey to produce a CoGbkResult (via
> ConstructCoGbkResultFn).
>
> Given the performance of CoGBK is greatly impacted based on the which
> elements are cached in the (finitely sized) in-memory results, it would be
> useful if CoGbkResult can use runtime information to prioritize which
> elements are stored in-memory.
