Constants

const (
	// PREFIX uses here to differentiate between denny etcd prefix and other service prefix
	// in etcd directory/files
	Prefix = "_DENNY_"
)

Functions

func DefaultBalancePolicy

func DefaultBalancePolicy() grpc.DialOption

DefaultBalancePolicy returns default grpc service config which required by new grpc API so client does not have to supply json config everytime

func Exist

func Exist(l []resolver.Address, addr string) bool

Exist checks if given addr is already exist in grpc resolver address list

func Remove

func Remove(s []resolver.Address, addr string) ([]resolver.Address, bool)

Remove removes an address from grpc resolver address list (because it's no longer available in naming registry)

Types

type Registry

type Registry interface {
	Register(addr string, ttl int) error
	UnRegister(addr string) error
	Build(target resolver.Target, cc resolver.ClientConn, opts resolver.BuildOptions) (resolver.Resolver, error)
	Scheme() string
	SvcName() string
}

Registry is based interface, which is composed of grpc resolver.Builder, resolver.Resolver and also contains method to register and unregister from naming storage
