All Implemented Interfaces:

java.io.Serializable, HasDisplayData

public abstract class RecommendationAIPredict
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 creates PredictResponse.PredictionResults.

It is possible to provide a catalog name to which you want to add the user event (defaults to "default_catalog"). It is possible to provide a event store to which you want to add the user event (defaults to "default_event_store"). A placement id for the recommendation engine placement to be used.

Description copied from class: PTransform

Override this method to specify how this PTransform should be expanded on the given InputT.

NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).
