I appreciate the effort to keep some usage of the constants here, but given that this is a) difficult to read, and b) already contains a "magic string" for loadBalancingConfig key anyway, I'd be tempted to do what https://github.com/grpc/grpc-go/blob/master/examples/features/load_balancing/client/main.go#L77 does, here and below:

Suggested change

	dialOpts = append(dialOpts, grpc.WithDefaultServiceConfig(fmt.Sprintf(`{"loadBalancingConfig": [{"%s":{}}]}`, roundrobin.Name)), grpc.WithResolvers(res))
	dialOpts = append(dialOpts, grpc.WithDefaultServiceConfig(`{"loadBalancingConfig": [{"round_robin":{}}]}`), grpc.WithResolvers(res))

Is it just me, or is configuring options using json instead of a struct a bit weird? Anyway, thanks for doing this!

I agree that it's probably a better idea to inline this.

[cpanato]

thanks so much the feedback and review

@cpanato Could you please ensure to run go mod tidy, if not yet done?

@mhutchinson any plans to have a release?

[mhutchinson]

@cpanato I wouldn't say that I had it on my TODO list, but it's probably about time we cut new releases. @pavelkalinnikov is making some changes that cross-cut some of the repos at the moment. When that flurry of work calms down, I think that would be a good time to cut releases of the various repos (this one, trillian, and transparency-dev/merkle are the main ones being affected at the moment).

[mhutchinson]

@cpanato hopefully you saw https://github.com/google/certificate-transparency-go/releases/tag/v1.1.3 :-)

thank you @mhutchinson
