Functions

func GetKeyPre

func GetKeyPre(serviceName string) string

func GetNodeId

func GetNodeId(serviceName string) string

func GetStableJobStore

Types

type DriverV2

type DriverV2 interface {
	// init driver
	Init(serviceName string, opts ...Option)
	// get nodeID
	NodeID() string
	// get nodes
	GetNodes(ctx context.Context) (nodes []string, err error)
	Start(ctx context.Context) (err error)
	Stop(ctx context.Context) (err error)
	// contains filtered or unexported methods
}

There is only one driver for one dcron. Tips for write a user-defined Driver by yourself.

1. Confirm that `Stop` and `Start` can be called for more times.
2. Must make `GetNodes` will return error when timeout.
