Methods

FeatureViewDirectWrite(IAsyncStreamReader<FeatureViewDirectWriteRequest>, IServerStreamWriter<FeatureViewDirectWriteResponse>, ServerCallContext)

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.

Parameters
Name Description
requestStream IAsyncStreamReaderFeatureViewDirectWriteRequest

Used for reading requests from the client.
responseStream IServerStreamWriterFeatureViewDirectWriteResponse

Used for sending responses back to the client.
context ServerCallContext

The context of the server-side call handler being invoked.
Returns
Type Description
Task

A task indicating completion of the handler.

FetchFeatureValues(FetchFeatureValuesRequest, ServerCallContext)

public virtual Task<FetchFeatureValuesResponse> FetchFeatureValues(FetchFeatureValuesRequest request, ServerCallContext context)

Fetch feature values under a FeatureView.

Parameters
Name Description
request FetchFeatureValuesRequest

The request received from the client.
context ServerCallContext

The context of the server-side call handler being invoked.
Returns
Type Description
TaskFetchFeatureValuesResponse

The response to send back to the client (wrapped by a task).

SearchNearestEntities(SearchNearestEntitiesRequest, ServerCallContext)

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.

Parameters
Name Description
request SearchNearestEntitiesRequest

The request received from the client.
context ServerCallContext

The context of the server-side call handler being invoked.
Returns
Type Description
TaskSearchNearestEntitiesResponse

The response to send back to the client (wrapped by a task).

responseStream IServerStreamWriterStreamingFetchFeatureValuesResponse

Used for sending responses back to the client.
context ServerCallContext

The context of the server-side call handler being invoked.
Returns
