Types

type Ketama

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

func NewKetama

func NewKetama(node, vnode int) *Ketama

New create a ketama consistent hashing struct

func NewKetama2

func NewKetama2(node []string, vnode int) *Ketama

New create a ketama consistent hashing struct use exist node slice

func (*Ketama) Node

func (k *Ketama) Node(key string) string

Node get a consistent hashing node by key

type UIntSlice

type UIntSlice []uint

Convenience types for common cases UIntSlice attaches the methods of Interface to []uint, sorting in increasing order.

func (UIntSlice) Len
