Datadog tracing + Opencensus tracing

[LiHaoTan]

Does Datadog tracing and Opencensus tracing work well together? For example, take the following code:

import (
	"context"
	"log"

	datadog "github.com/DataDog/opencensus-go-exporter-datadog"
	opencensustrace "go.opencensus.io/trace"
	"gopkg.in/DataDog/dd-trace-go.v1/ddtrace/tracer"
)

func main() {
	exporter, err := datadog.NewExporter(datadog.Options{Service: "my-app"})
	if err != nil {
		log.Fatal(err)
	}
	defer exporter.Stop()

	opencensustrace.RegisterExporter(exporter)

	opencensustrace.ApplyConfig(opencensustrace.Config{
		DefaultSampler: opencensustrace.AlwaysSample(),
	})

	span, ctx :=  tracer.StartSpanFromContext(context.Background(), "/foo")
	datadogSpan(ctx)
	openCensusSpan(ctx)
	span.Finish()
}

func datadogSpan(ctx context.Context) {
	span, ctx := tracer.StartSpanFromContext(ctx, "datadogSpan")
	defer span.Finish()
}

func openCensusSpan(ctx context.Context) {
	ctx, span := opencensustrace.StartSpan(ctx, "opencensusSpan")
	defer span.End()
}

Will the datadog span and opencensus span have the same trace id?

I have the opencensusSpan that shows in Datadog under the /foo resource but the datadogSpan does not have a parent trace. I will relay this issue to https://github.com/DataDog/opencensus-go-exporter-datadog.
