Functions

func NewCountValues

func NewCountValues(pool *model.VectorPool, next model.VectorOperator, param string, by bool, grouping []string, opts *query.Options) model.VectorOperator

func NewHashAggregate

func NewHashAggregate(
	points *model.VectorPool,
	next model.VectorOperator,
	paramOp model.VectorOperator,
	aggregation parser.ItemType,
	by bool,
	labels []string,
	opts *query.Options,
) (model.VectorOperator, error)

func NewKHashAggregate

func NewKHashAggregate(
	points *model.VectorPool,
	next model.VectorOperator,
	paramOp model.VectorOperator,
	aggregation parser.ItemType,
	by bool,
	labels []string,
	opts *query.Options,
) (model.VectorOperator, error)

func Quantile

func Quantile(q float64, points []float64) float64

func SumCompensated

func SumCompensated(s []float64) float64

SumCompensated returns the sum of the elements of the slice calculated with greater accuracy than Sum at the expense of additional computation.
