Name resolution in C# / grpclb selection

[Benjamin Krämer]

I had the problem already some years ago (https://github.com/grpc/grpc/issues/11879). In the meantime, we helped us out by using grpclb for name resolution purposes. We also discussed about other solutions: https://github.com/grpc/grpc/pull/13639

There also is the long plan to have a public resolver API discussed in here https://github.com/grpc/grpc/pull/16617

Sadly for us, grpclb does not seem to be selected by default anymore in favor of xDS and therefore now broke our code base. I have also not found a way to set the service config in C# to select the grpclb LB policy directly. Can anyone point me into the direction of how to set it in C#? I assume there's a channel option?

I would like to avoid having to change our workaround from grpclb to xDS and hope that there will be some progress on the public resolver API instead.

I did this using C# gRPC lib 2.31.0:

GRPC_VERBOSITY=DEBUG

GRPC_TRACE=cares_resolver,cares_address_sorting,client_channel_call,client_channel_routing,connectivity_state,glb

In the past, once AAAA and A DNS requests failed, it tried SRV request. The DNS server to use is 127.0.0.1:8010 and the channel target is dns://127.0.0.1:8010/test.my-company.com

The grpclb selection logic changed recently.  For details, see https://github.com/grpc/proposal/blob/master/A26-grpclb-selection.md.

In order to select grpclb, you'll need to do two things:

1. Set the GRPC_ARG_DNS_ENABLE_SRV_QUERIES channel arg to 1.  (This has been required since the c-ares based DNS resolver became the default, although it might not have been required in earlier versions if you explicitly enabled the c-ares resolver.)

2. Set a service config that looks something like this:

{

  "loadBalancingConfig":[
    { "grpclb":{} }
  ]
}

There are two ways to inject the service config:

• Set it via a TXT record, as per https://github.com/grpc/proposal/blob/master/A2-service-configs-in-dns.md.  This requires setting the GRPC_ARG_SERVICE_CONFIG_DISABLE_RESOLUTION to 0.
• Passing the service config into the channel via the GRPC_ARG_SERVICE_CONFIG channel arg.
  

I hope this information is helpful.

I finally found some options that bring me the grpclb back. But connecting takes around 15-25 seconds...

```

new ChannelOption("grpc.lb_policy_name", "grpclb"),
new ChannelOption("grpc.service_config", "{\"serviceConfig\":{\"load_balancing_config\":{ \"grpclb\": {} },\"waitForReady\":true}}"),
new ChannelOption("grpc.dns_enable_srv_queries", 1)

```

See https://github.com/grpc/grpc/issues/24018#issuecomment-684991069 for the sample code and log file.

@Mark: Thanks for the input, that helped in finding the names (as there are no defines for that in C#).

Made a separate issue for the delays: https://github.com/grpc/grpc/issues/24042
