README
Consistent Hashing
A Go library that implements Consistent Hashing
This package is implemented based on golang/groupcache package with some improvements
Definitions in this README:
node
: Refers to the key which is going to be stored in the hash ring or hash table
rKey
: Refers to the request hash which is not going to be stored, it's used to find the upper closest node in the hash ring to the rKey
Improvements:
Remove
function added - sort and remove a node from the hash ring- int hashes replaced with uint32
- Number of replicas is now configurable while adding new node
Note: This is useful when capacity is not the same for all nodes
Usage
import (
chash "github.com/mbrostami/consistenthash"
)
// Create ConsistentHash with 2 replicas
ch := chash.NewConsistentHash(2, nil)
ch.Add("127.0.0.1:1001") // node 1
ch.Add("127.0.0.1:1002") // node 2
ch.AddReplicas("127.0.0.1:1003", 4) // node3 has more capacity so possibility to get assigned request is higher than other nodes
rKey := "something like request url"
node := ch.Get(rKey) // find upper closest node
fmt.println(node) // this will print out one of the nodes
