cc @TomAugspurger I think something like this is what is needed for #34872.
If this were a "real" PR, I'd probably not put
consolidate
as aDataFrame.__init__
kwarg but instead set it toTrue
and only change it toFalse
based on thecopy
kwarg.The usage in core.ops is not necessary, but is an example of where we can get a perf bump.
