The UDP protocol is based on a format close to JSON, but not fully compliant ; for example, the specs specify that an object can hold multiple properties with the same index. VaultServer type:. gNOI uses gRPC as the transport protocol and the configuration is same as that of gRPC. The beauty of protobuf is there is a single, canonical definition of your API. To call this API, you must: Sync your custom content manually at least once. This time I was trying to setup Clound Endpoint/gRPC to work locally. Any problems email [email protected] Watch Queue Queue. Not that I know anything about the grpc codebase, but in my experience it is often easier to implement timeouts at a higher level instead of tweaking several socket options. This approach is only for testing purposes, because it creates a race condition, since we cannot tell whether the watchNotif or the configure will run first. func (s *Server) newHTTP2Transport(c net.
