11. class TransientFeature extends Serializable

    

    Proxy class to be used by Op Stages that holds a valid reference to a feature on the master node without having to serialize the entire Feature to worker nodes.

    Proxy class to be used by Op Stages that holds a valid reference to a feature on the master node without having to serialize the entire Feature to worker nodes. Only the data that the worker might need is serialized, eg name, isResponse, and isRaw
