Functions

func ApplyClusterMetadataConfigProvider added in v1.14.0 

func ApplyClusterMetadataConfigProvider(
	logger log.Logger,
	config *config.Config,
	persistenceServiceResolver resolver.ServiceResolver,
	persistenceFactoryProvider persistenceClient.FactoryProviderFn,
	customDataStoreFactory persistenceClient.AbstractDataStoreFactory,
) (*cluster.Config, config.Persistence, error)

ApplyClusterMetadataConfigProvider performs a config check against the configured persistence store for cluster metadata. If there is a mismatch, the persisted values take precedence and will be written over in the config objects. This is to keep this check hidden from downstream calls. TODO: move this to cluster.fx

func InterruptCh 

func InterruptCh() <-chan interface{}

func PersistenceFactoryProvider added in v1.16.0 

func PersistenceFactoryProvider() persistenceClient.FactoryProviderFn

func ServerLifetimeHooks added in v1.14.0 

func ServerLifetimeHooks(
	lc fx.Lifecycle,

func ServerOptionsProvider(opts []ServerOption) (serverOptionsProvider, error)

func StopService added in v1.16.0 

func StopService(logger log.Logger, app *fx.App, svcName string, stopChan chan struct{})
