Types

type AddNodesInner

type AddNodesInner struct {
	Step func(tick int64) uint64
}

AddNodesInner adds nodes.

func (*AddNodesInner) Type

func (w *AddNodesInner) Type() string

Type implements the EventInner interface.

type Case

type Case struct {
	Stores          []*Store
	Regions         []Region
	MaxID           uint64
	RegionSplitSize int64
	RegionSplitKeys int64
	Events          []EventInner

	Checker CheckerFunc // To check the schedule is finished.
}

Case represents a test suite for simulator.

func NewCase

func NewCase(name string) *Case

NewCase creates a new case.

type CheckerFunc

type CheckerFunc func(*core.RegionsInfo) bool

CheckerFunc checks if the scheduler is finished.

type DeleteNodesInner
