TransportServer,TransportClientFactory, and to setup Netty Channel pipelines with aorg.apache.spark.network.server.TransportChannelHandler.There are two communication protocols that the TransportClient provides, control-plane RPCs and data-plane "chunk fetching". The handling of the RPCs is performed outside of the scope of the TransportContext (i.e., by a user-provided handler), and it is responsible for setting up streams which can be streamed through the data plane in chunks using zero-copy IO.
The TransportServer and TransportClientFactory both create a TransportChannelHandler for each channel. As each TransportChannelHandler contains a TransportClient, this enables server processes to send messages back to the client on an existing channel.
