Description

The grpc.Server is unexported within flight.Server (code ref); therefore, it's not possible to register additional grpc services, such as health check, reflection, on the flight.Server.

Usage:

import (
	"google.golang.org/grpc/health"
	"google.golang.org/grpc/health/grpc_health_v1"
	"google.golang.org/grpc/reflection"
)


	s := flight.NewFlightServer()

	// Enable health check.
	grpc_health_v1.RegisterHealthServer(s, health.NewServer())

	// Enable reflection for grpcurl.
	reflection.Register(s)
