Ruben Berenguel commented on SPARK-23904:
-----------------------------------------

[~staslos] Interesting, thanks. I guess this still could not help with [~igreenfi] problem,
since in his sample code it's just that one query that generates a monstrously large plan.
But good to know that for more normal cases there is a workaround.

> Spark create the text representation of query in any case even if I don't need it.
> That causes many garbage object and unneeded GC...
