Batch serves feature values to BigQuery destination

Parameters

Name	Description
bq_destination_output_uri	str Required. BigQuery URI to the detination table. .. rubric:: Example 'bq://project.dataset.table_name' It requires an existing BigQuery destination Dataset, under the same project as the Featurestore.
serving_feature_ids	Dict[str, List[str]] Required. A user defined dictionary to define the entity_types and their features for batch serve/read. The keys of the dictionary are the serving entity_type ids and the values are lists of serving feature ids in each entity_type. .. rubric:: Example serving_feature_ids = { 'my_entity_type_id_1': ['feature_id_1_1', 'feature_id_1_2'], 'my_entity_type_id_2': ['feature_id_2_1', 'feature_id_2_2'], }
read_instances_uri	str Required. Read_instances_uri can be either BigQuery URI to an input table, or Google Cloud Storage URI to a csv file. .. rubric:: Example 'bq://project.dataset.table_name' or "gs://my_bucket/my_file.csv" Each read instance should consist of exactly one read timestamp and one or more entity IDs identifying entities of the corresponding EntityTypes whose Features are requested. Each output instance contains Feature values of requested entities concatenated together as of the read time. An example read instance may be foo_entity_id, bar_entity_id, 2020-01-01T10:00:00.123Z. An example output instance may be foo_entity_id, bar_entity_id, 2020-01-01T10:00:00.123Z, foo_entity_feature1_value, bar_entity_feature2_value. Timestamp in each read instance must be millisecond-aligned. The columns can be in any order. Values in the timestamp column must use the RFC 3339 format, e.g. 2012-07-30T10:43:17.123Z.
pass_through_fields	List[str] Optional. When not empty, the specified fields in the read_instances source will be joined as-is in the output, in addition to those fields from the Featurestore Entity. For BigQuery source, the type of the pass-through values will be automatically inferred. For CSV source, the pass-through values will be passed as opaque bytes.
feature_destination_fields	Dict[str, str] Optional. A user defined dictionary to map a feature's fully qualified resource name to its destination field name. If the destination field name is not defined, the feature ID will be used as its destination field name. .. rubric:: Example feature_destination_fields = { 'projects/123/locations/us-central1/featurestores/fs_id/entityTypes/et_id1/features/f_id11': 'foo', 'projects/123/locations/us-central1/featurestores/fs_id/entityTypes/et_id2/features/f_id22': 'bar', }
serve_request_timeout	float Optional. The timeout for the serve request in seconds.
