Data wrangling and mapping from one schema to another.
DataVec comes with the ability to serialize transforms, which allows them to be more portable when they're needed for production environments. A TransformProcess is serialzied to a human-readable format such as JSON and can be saved as a file.
The code below shows how you can serialize the transform process tp.
String serializedTransformString = tp.toJson()
When you want to reinstantiate the transform process, call the static from<format> method.
