Java, gRPC and Context propagation

Does anyone have a working example of io.grpc.Context propagation between client (stub) and server using gRPC in java?

My understanding is that it's not possible and I must use Metadata instead. Am I correct?

Online I have found only examples using Header rather than Context.

Thanks!

io.grpc.Context is for local propagation only, like between threads or even on the same thread. gRPC purposefully does not propagate items from it automatically. You can use a ClientInterceptor to copy a value from the Context to the Metadata.
