php_hashtable's Introduction

一致性hash演示

演示地址：　http://ht.hotfive.cn/

php_hashTable

  1. php hashTable的实现,
  2. hash码冲突的解决方法,
  3. 一致性hash的php实现

一致性hash算法演示(服务端要求php环境)

这只是一个简单版本,纯供个人演示与理解使用,建议

  1. fork 该项目
  2. clone 到本地
  3. 将consistency_hash放到web环境下面,一定要可以使用IP|域名能访问到, 因为需要请求php端的hash算法  1. 配置完成之后,需要在js/hash.js中的$.get()方法中修改下你本地服务器的地址,否则不能动态添加 注意  
  4. 在浏览器中访问index.html页面可看到效果

接下来要做的

  1. 添加localstorage
  2. 添加条形hash桶的显示

php_hashtable's Issues

不解决冲突的hashtable，在做hashcode时候存在负数bug

hashTable\HashTable.php文件，hashFunc方法，会生成一个负数，在SplFixedArray数组中没有负数范围
建议改为如下:

private function hashFunc($key){
            $sum = crc32($key);
            $index = $sum % $this->size;
            if($index<0){
                return $index + $this->size;
            }
            return $index;
        }
