James Taylor commented on PHOENIX-944:
--------------------------------------
To prevent having to copy the byte array, I'd have a compare function rather
than a getGroupingKey (as you can compare in place). The wrapKeyValueAsResult
is a good solution, I think.
> Support derived tables in FROM clause that needs extra steps of client-side
> aggregation or other processing
