A service for fetching feature values from the online store.
Equality
Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection>
objects compare equal. Objects that compare equal share the same underlying resources.
Performance
Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.
Thread Safety
Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions
FetchFeatureValues(std::string const &, google::cloud::aiplatform::v1::FeatureViewDataKey const &, Options)
Fetch feature values under a FeatureView.
Parameters | |
---|---|
Name | Description |
feature_view |
std::string const &
Required. FeatureView resource format |
data_key |
google::cloud::aiplatform::v1::FeatureViewDataKey const &
Optional. The request key to fetch feature values for. |
opts |
Options
Optional. Override the class-level options, such as retry and backoff policies. |
Returns | |
---|---|
Type | Description |
StatusOr< google::cloud::aiplatform::v1::FetchFeatureValuesResponse > |
the result of the RPC. The response message type (google.cloud.aiplatform.v1.FetchFeatureValuesResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the |
FetchFeatureValues(google::cloud::aiplatform::v1::FetchFeatureValuesRequest const &, Options)
Fetch feature values under a FeatureView.
Parameters | |
---|---|
Name | Description |
request |
google::cloud::aiplatform::v1::FetchFeatureValuesRequest const &
Unary RPCs, such as the one wrapped by this function, receive a single |
opts |
Options
Optional. Override the class-level options, such as retry and backoff policies. |
Returns | |
---|---|
Type | Description |
StatusOr< google::cloud::aiplatform::v1::FetchFeatureValuesResponse > |
the result of the RPC. The response message type (google.cloud.aiplatform.v1.FetchFeatureValuesResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the |
SearchNearestEntities(google::cloud::aiplatform::v1::SearchNearestEntitiesRequest const &, Options)
Search the nearest entities under a FeatureView.
Search only works for indexable feature view; if a feature view isn't indexable, returns Invalid argument response.
