[grpc-io] Re: Communication of grpc streaming between C# and C++

['AJ Heller' via grpc.io]

Hi Zijian. Basic streaming communications should work fine between 
languages. Can you be more specific about your errors, or produce a minimum 
reproducible example?

[grpc-io] gRFC A36: xDS-Enabled Servers

['Eric Anderson' via grpc.io]

Please review and comment. The gRFC is at
https://github.com/grpc/proposal/pull/214. The gRFC covers new APIs and
their plumbing to allow having xDS-enabled servers. The precise C++/wrapped
language APIs are not covered, but an idea of what they may look like is
covered. Java and Go have their concrete API designs presented.

A36 itself doesn't provide any xDS features, but is the basis for them to
be built without applications needing to make code changes for each added
xDS feature. For an xDS feature, see the related gRFC A29: xDS-Based
Security for gRPC Clients and Servers
.

Re: [grpc-io] Anyone adding HTTP/3 support for gRPC?

['Eric Anderson' via grpc.io]

I *think* there have been some HTTP/3 experiments, but nothing actively
being worked on. For mobile though, grpc-java and grpc-objc clients do have
support for Cronet, and Cronet supports HTTP/3. Cronet is basically
Chrome's networking stack built into a library. There's no server support,
but that is generally not a problem because backends would already be
behind a reverse proxy.

Re: [grpc-io] Re: (grpc-java) Detecting client network disconnect and connect

['Eric Gribkoff' via grpc.io]

I believe that
https://grpc.github.io/grpc-java/javadoc/io/grpc/ManagedChannel.html#getState-boolean-
and
https://grpc.github.io/grpc-java/javadoc/io/grpc/ManagedChannel.html#notifyWhenStateChanged-io.grpc.ConnectivityState-java.lang.Runnable-
are the APIs that you are looking for.

Thanks,

Eric

Re: [grpc-io] gRPC-Java method overloading

['Eric Gribkoff' via grpc.io]

Assuming that you are asking about overloading the method names defined in
your service's proto file, this StackOverflow question and answer addresses
this issue:
https://stackoverflow.com/questions/65034685/is-it-possible-the-grpc-functions-overloading/65034755#65034755

Thanks,

Eric
