  • closes #xxxx (Replace xxxx with the GitHub issue number)
  • Tests added and passed if fixing a bug or adding a new feature
  • All code checks passed.
  • Added type annotations to new arguments/methods/functions.
  • Added an entry in the latest doc/source/whatsnew/vX.X.X.rst file if fixing a bug or adding a new feature.

This also gets rid of the usage of the deprecated fastpath argument.

In the no-op case (e.g. the UDF is lambda x: x), we go from 300ms to 200ms.
