### What would you like to happen? MLTransform currently each row into columnts that has to be preprocessed by TFT and columns that should not, due to TFT requiring a schema for all colmunts. This creates a GBK step and requires adding a unique key per each element. We can try out different implementations that don't require a GBK, for example by encoding not-to-be processed columns as bytes and passing them through TFT, then decoding. It might reduce the total cost or improve performance. ### Issue Priority Priority: 2 (default / most feature requests should be filed as P2) ### Issue Components - [X] Component: Python SDK - [ ] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [ ] Component: IO connector - [ ] Component: Beam YAML - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
