Let's say a client and a server has both setup a streaming rpc.
A client has sent up about 3 valid grpc message and the server acknowledge this with a headers frame and started processing the grpc message.
The client then sent a truncated grpc message with END_STREAM (or malformed protobuf).
Does the server cancels the processing of the received 3 grpc message and immediately send a DATA_LOSS trailer?
or continues the processing of the messages and send its response with DATA_LOSS trailer?
