Instead of modifying this method's signature, I slightly prefer adding an overload named
transformDownWithSubqueriesAndPruning
in order to remain consistent with the naming conventions for other transform methods.Adding a new method also avoids introducing source or binary compatibility issues for third-party code that calls Catalyst APIs. Technically speaking, Catalyst APIs are considered internal to Spark and are subject to change between minor releases (see source), but I think it's nice to try to avoid API breakage when feasible.
I also ran into problems when trying to call
transformDownWithSubqueries
without supplying any arguments in the first argument group: callingtransformDownWithSubqueries() { f }
resulted in confusing compilation errors.As a result, I'm going to submit a followup to this PR to split this into two methods as I've suggested above.
