Properties

BigqueryReadInstances

public BigQuerySource BigqueryReadInstances { get; set; }

Similar to csv_read_instances, but from BigQuery source.

Property Value
TypeDescription
BigQuerySource

CsvReadInstances

public CsvSource CsvReadInstances { get; set; }

Each read instance consists 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.

csv_read_instances are read instances stored in a plain-text CSV file. The header should be: [ENTITY_TYPE_ID1], [ENTITY_TYPE_ID2], ..., timestamp

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.

Property Value
TypeDescription
CsvSource

Destination

public FeatureValueDestination Destination { get; set; }

Required. Specifies output location and format.

Property Value
TypeDescription
FeatureValueDestination

EntityTypeSpecs

public RepeatedField<BatchReadFeatureValuesRequest.Types.EntityTypeSpec> EntityTypeSpecs { get; }

Required. Specifies EntityType grouping Features to read values of and settings.

Property Value
TypeDescription
RepeatedFieldBatchReadFeatureValuesRequestTypesEntityTypeSpec

Featurestore

public string Featurestore { get; set; }

Required. The resource name of the Featurestore from which to query Feature values. Format: projects/{project}/locations/{location}/featurestores/{featurestore}

Property Value
TypeDescription
string

FeaturestoreAsFeaturestoreName

public FeaturestoreName FeaturestoreAsFeaturestoreName { get; set; }

FeaturestoreName-typed view over the Featurestore resource name property.

Property Value
TypeDescription
FeaturestoreName

PassThroughFields

public RepeatedField<BatchReadFeatureValuesRequest.Types.PassThroughField> PassThroughFields { get; }

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.

Property Value
TypeDescription
RepeatedFieldBatchReadFeatureValuesRequestTypesPassThroughField

public BatchReadFeatureValuesRequest.ReadOptionOneofCase ReadOptionCase { get; }
Property Value
TypeDescription
BatchReadFeatureValuesRequestReadOptionOneofCase

StartTime

public Timestamp StartTime { get; set; }

Optional. Excludes Feature values with feature generation timestamp before this timestamp. If not set, retrieve oldest values kept in Feature Store. Timestamp, if present, must not have higher than millisecond precision.

Property Value
TypeDescription
