zhengruifeng commented on issue #26547: [SPARK-29914][ML] ML models attach metadata in `transform`/`transformSchema` URL: https://github.com/apache/spark/pull/26547#issuecomment-556853242 @viirya Thanks for reviewing! > this change adds metadata to many classes, is metadata useful for them all? I think it maybe nice to provide as much metadata as possible metadata in the output datasets, since downstream impls may use it in some way. Currently, some impls provide metadata, others not. I guess there is not a clear criteria to attach the metadata.
