public abstract class RecommendationAIWriteUserEvent
extends PTransform<PCollection<com.google.api.client.json.GenericJson>,PCollectionTuple>

A PTransform using the Recommendations AI API (https://cloud.google.com/recommendations). Takes an input PCollection of GenericJsons and converts them to and creates UserEvents.
