public virtual Task FeatureViewDirectWrite(IAsyncStreamReader<FeatureViewDirectWriteRequest> requestStream, IServerStreamWriter<FeatureViewDirectWriteResponse> responseStream, ServerCallContext context)
Bidirectional streaming RPC to directly write to feature values in a
feature view. Requests may not have a one-to-one mapping to responses and
responses may be returned out-of-order to reduce latency.
public virtual Task<SearchNearestEntitiesResponse> SearchNearestEntities(SearchNearestEntitiesRequest request, ServerCallContext context)
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.
public virtual Task StreamingFetchFeatureValues(IAsyncStreamReader<StreamingFetchFeatureValuesRequest> requestStream, IServerStreamWriter<StreamingFetchFeatureValuesResponse> responseStream, ServerCallContext context)
Bidirectional streaming RPC to fetch feature values under a FeatureView.
Requests may not have a one-to-one mapping to responses and responses may
be returned out-of-order to reduce latency.
