TransportChannelHandler

class TransportChannelHandler extends SimpleChannelInboundHandler[Message]

The single Transport-level Channel handler which is used for delegating requests to the TransportRequestHandler and responses to the TransportResponseHandler.

All channels created in the transport layer are bidirectional. When the Client initiates a Netty Channel with a RequestMessage (which gets handled by the Server's RequestHandler), the Server will produce a ResponseMessage (handled by the Client's ResponseHandler). However, the Server also gets a handle on the same Channel, so it may then begin to send RequestMessages to the Client. This means that the Client also needs a RequestHandler and the Server needs a ResponseHandler, for the Client's responses to the Server's requests.

This class also handles timeouts from a io.netty.handler.timeout.IdleStateHandler. We consider a connection timed out if there are outstanding fetch or RPC requests but no traffic on the channel for at least requestTimeoutMs. Note that this is duplex traffic; we will not timeout if the client is continuously sending but getting no responses, for simplicity.
