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).

GenerateFetchAccessToken(GenerateFetchAccessTokenRequest, ServerCallContext)

public virtual Task<GenerateFetchAccessTokenResponse> GenerateFetchAccessToken(GenerateFetchAccessTokenRequest request, ServerCallContext context)

RPC to generate an access token for the given feature view. FeatureViews under the same FeatureOnlineStore share the same access token.

Parameters
Name	Description
`request`	`GenerateFetchAccessTokenRequest` The request received from the client.
`context`	`ServerCallContext` The context of the server-side call handler being invoked.

Returns
Type	Description
`TaskGenerateFetchAccessTokenResponse`	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).

StreamingFetchFeatureValues(IAsyncStreamReader<StreamingFetchFeatureValuesRequest>, IServerStreamWriter<StreamingFetchFeatureValuesResponse>, ServerCallContext)

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.

Parameters
Name	Description
`requestStream`	`IAsyncStreamReaderStreamingFetchFeatureValuesRequest` Used for reading requests from the client.
`responseStream`	`IServerStreamWriterStreamingFetchFeatureValuesResponse` 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.
