Functions

func Register

func Register(cs ClusterSpecifier)

Register registers the ClusterSpecifierPlugin to the ClusterSpecifier map. cs.TypeURLs() will be used as the types for this ClusterSpecifierPlugin.

NOTE: this function must only be called during initialization time (i.e. in an init() function), and is not thread-safe. If multiple cluster specifier plugins are registered with the same type URL, the one registered last will take effect.

Types

type BalancerConfig

type BalancerConfig []map[string]interface{}

BalancerConfig is the Go Native JSON representation of a balancer configuration.

type ClusterSpecifier

type ClusterSpecifier interface {
	// TypeURLs are the proto message types supported by this
	// ClusterSpecifierPlugin. A ClusterSpecifierPlugin will be registered by
	// each of its supported message types.
	TypeURLs() []string
	// ParseClusterSpecifierConfig parses the provided configuration
	// proto.Message from the top level RDS configuration. The resulting
	// BalancerConfig will be used as configuration for a child LB Policy of the
	// Cluster Manager LB Policy.
	ParseClusterSpecifierConfig(proto.Message) (BalancerConfig, error)
}

ClusterSpecifier defines the parsing functionality of a Cluster Specifier.

func Get

func Get(typeURL string) ClusterSpecifier

Get returns the ClusterSpecifier registered with typeURL.

If no cluster specifier is registered with typeURL, nil will be returned.
