Functions

func CreateStorageAxis

func CreateStorageAxis(regions region.RegionsInfo, strategy matrix.Strategy) matrix.Axis

CreateStorageAxis converts the RegionsInfo to a StorageAxis.

func IntoResponseAxis

func IntoResponseAxis(storageAxis matrix.Axis, baseTag region.StatTag) matrix.Axis

IntoResponseAxis converts StorageAxis to ResponseAxis.

func IntoStorageAxis

func IntoStorageAxis(responseAxis matrix.Axis, strategy matrix.Strategy) matrix.Axis

IntoStorageAxis converts ResponseAxis to StorageAxis.

Types

type LayerConfig

type LayerConfig struct {
	Len   int
	Ratio int
}

LayerConfig is the configuration of layerStat.

type Stat

type Stat struct {
	// contains filtered or unexported fields
}

Stat is composed of multiple layerStats.

func NewStat

func NewStat(ctx context.Context, wg *sync.WaitGroup, provider *region.PDDataProvider, cfg StatConfig, strategy matrix.Strategy, startTime time.Time) *Stat

NewStat generates a Stat based on the configuration.

func (*Stat) Append

func (s *Stat) Append(regions region.RegionsInfo, endTime time.Time)

Append adds the latest full statistics.

func (*Stat) Range

func (s *Stat) Range(startTime, endTime time.Time, startKey, endKey string, baseTag region.StatTag) matrix.Plane

Range returns a sub Plane with specified range.

type StatConfig

type StatConfig struct {
	LayersConfig []LayerConfig
}

StatConfig is the configuration of Stat.
