> DataSourceV2 currently pushes filters and projected columns in the optimized plan, but this requires creating and configuring a reader multiple times and prevents the v2 relation's output from being a fixed argument of the relation case class. It is also much cleaner (see PR [#21262|https://github.com/apache/spark/pull/21262]).
