public class ModelMapperAdapter
extends org.apache.flink.api.common.functions.RichMapFunction<org.apache.flink.types.Row,org.apache.flink.types.Row>

A class that adapts a ModelMapper to a Flink RichMapFunction so the model can be loaded in a Flink job.

This adapter class hold the target ModelMapper and it's ModelSource. Upon open(), it will load model rows from ModelSource into ModelMapper.
