Constants

const (
	OptionTypeTimeout = 0x600
	OptionTypeLogger  = 0x601
)

const GlobalKeyPrefix = "distributed-cron:"

GlobalKeyPrefix is a global redis key prefix

Functions

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)

	// register node to remote server (like etcd/redis),
	// will create a goroutine to keep the connection.
	// And then continue for other work.
	Start(ctx context.Context) (err error)

	// stop the goroutine of keep connection.
	Stop(ctx context.Context) (err error)

	WithOption(opt Option) (err error)
}

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.
