Description

#2373 introduced a big delay when generating the output schema. Instead we can get the schema from the input df schema and label columns.

Fixes #2536.

Review process to land

  1. All tests and other checks must succeed.
  2. At least one member of the technical steering committee must review and approve.
  3. If any member of the technical steering committee requests changes, they must be addressed.

@tgaddair Please check here. Is it OK to always assume label_cols and output_cols are 1:1 matching?
