Re: [grpc-io] grpc java biDirectional streaming client retry when onError is called

[jimmy . hsu . ruckus]

Hi, 

I have the same question. How do I know the messages have delivered to the 
server side?
The client can get and store all messages in the interceptor. However I 
can't get any error if the connection has any problem.

Observer.onError can't get any information about sent messages.

Re: [grpc-io] grpc java biDirectional streaming client retry when onError is called

['Spencer Fang' via grpc.io]

gRPC does not store messages that are already sent, so you would have to
store that message by yourself somewhere. I think you would also need to do
this for ongoing RPCs as well because there may be 1 or more messages sent
by the client when the server is killed.

[grpc-io] grpc java biDirectional streaming client retry when onError is called

[eleanore . jin]

Hi, 

My project uses gRPC bi-directional streaming call. We are not using grpc 
LB, but have our own logic implemented to select which server. So when I 
kill one of the server, client StreamObserver.onError is called and the 
original message is lost. 

I just wonder is there anyway to obtain the original message, so that we 
can re-select another server to retry?

Thanks a lot!
