batchReadFeatureValues method

@override Future<Operation<BatchReadFeatureValuesResponse, BatchReadFeatureValuesOperationMetadata>> batchReadFeatureValues(BatchReadFeatureValuesRequest request)

Batch reads Feature values from a Featurestore.

This API enables batch reading Feature values, where each read instance in the batch may read Feature values of entities from one or more EntityTypes. Point-in-time correctness is guaranteed for Feature values of each read instance as of each instance's read timestamp.

Throws a http.ClientException if there were problems communicating with the API service. Throws a ServiceException if the API method failed for any reason.

Returns an Operation representing the status of the long-running operation.

When complete, Operation.done will be true. If successful, Operation.responseAsMessage will contain the operation's result.
