> I have a pipeline that operates on some large objects, and the additional
> overhead of creating a deep copy of them on intermediate outputs (i.e., DoFns
> w/more than one child operation) when I know that all of their consumers are
> going to be read-only is slowing down my runtime quite a bit. I'd like to
> have an option that would allow me to disable intermediate deep copies on a
> DoFn-by-DoFn basis and/or across an entire pipeline run when I know that it's
> safe to do.
