var IDAllocator idAllocator

IDAllocator is used to alloc unique ID.

Types

type AddNodesDescriptor

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

AddNodesDescriptor adds nodes.

func (*AddNodesDescriptor) Type

func (*AddNodesDescriptor) Type() string

Type implements the EventDescriptor interface.

type Case

type Case struct {
	Stores          []*Store
	Regions         []Region
	RegionSplitSize int64
	RegionSplitKeys int64
	Events          []EventDescriptor
	TableNumber     int

	Checker CheckerFunc // To check the schedule is finished.
	Rules   []*pdHttp.Rule
	Labels  typeutil.StringSlice
}

Case represents a test suite for simulator.

func NewCase

func NewCase(name string, simConfig *config.SimConfig) *Case

NewCase creates a new case.

type CheckerFunc

type CheckerFunc func([]*metapb.Store, *core.RegionsInfo, []info.StoreStats) bool

CheckerFunc checks if the scheduler is finished.

type DeleteNodesDescriptor

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

DeleteNodesDescriptor removes nodes.

func (*DeleteNodesDescriptor) Type

func (*DeleteNodesDescriptor) Type() string

Type implements the EventDescriptor interface.

type EventDescriptor

type EventDescriptor interface {
	Type() string
}

EventDescriptor is a detail template for custom events.

type ReadFlowOnRegionDescriptor

type ReadFlowOnRegionDescriptor struct {
	Step func(tick int64) map[uint64]int64
}

ReadFlowOnRegionDescriptor reads bytes in some region.

func (*ReadFlowOnRegionDescriptor) Type

func (*ReadFlowOnRegionDescriptor) Type() string

Type implements the EventDescriptor interface.

type Region

type Region struct {
	ID     uint64
	Peers  []*metapb.Peer
	Leader *metapb.Peer
	Size   int64
