}

BootstrapParams holds the set of parameters needed to bootstrap a service

func (*BootstrapParams) UpdateLoggerWithServiceName

func (params *BootstrapParams) UpdateLoggerWithServiceName(name string)

UpdateLoggerWithServiceName tag logging with service name from the top level

type RingpopFactory

type RingpopFactory interface {
	// CreateRingpop vends a bootstrapped ringpop object
	CreateRingpop(d *yarpc.Dispatcher) (*ringpop.Ringpop, error)
}

RingpopFactory provides a bootstrapped ringpop

type Service

type Service interface {
	// GetHostName returns the name of host running the service
	GetHostName() string

	// Start the service
	Start()

	// Stop stops the service
	Stop()

	GetLogger() bark.Logger

	GetMetricsClient() metrics.Client

	GetClientBean() client.Bean

	GetDispatcher() *yarpc.Dispatcher

	GetMembershipMonitor() membership.Monitor

	GetHostInfo() *membership.HostInfo

	// GetClusterMetadata returns the service cluster metadata
	GetClusterMetadata() cluster.Metadata

	// GetMessagingClient returns the messaging client against Kafka
	GetMessagingClient() messaging.Client
}

Service is the interface which must be implemented by all the services

func New

func New(params *BootstrapParams) Service

New instantiates a Service Instance TODO: have a better name for Service.

func NewTestService

func NewTestService(clusterMetadata cluster.Metadata, messagingClient messaging.Client, metrics metrics.Client,
	clientBean client.Bean, logger bark.Logger) Service

NewTestService is the new service instance created for testing
