Jump Consistent Hashing algorithm in Java Abstract from the paperhttp://arxiv.org/abs/1406.2294: We present jump consistent hash, a fast, minimal memory, consistent hash algorithm that can be expressed in about
change =0foriteminrange(ITEMS): h = _hash(item) >> PARTITION p = bisect_left(ring, h) p2 = bisect_left(ring, h) n = part2node[p] % NODES n2 = part2node2[p] % NODES2ifn2 != n: change +=1 小结 本节详细讲述了一致性hash的原理,后续我们将学习如何使用 java 实现一个工具。
Consistent hashing,一致性hash最早是由David Karger等人在《Consistent Hashing and Random Trees:Distributed Caching Protocols for Relieving Hot Spots on the World Wide Web》论文中提出的,为的是解决分布式网络中减少或消除热点问题的发生而提出的缓存协议。
There are clients for several systems, such as Memcached and Redis, that include support for consistent hashing out of the box. Alternatively, you can implement the algorithm yourself, in your language of choice, and that should be relatively easy once the concept is understood. ...
本文整理了Java中com.google.common.hash.Hashing.consistentHash()方法的一些代码示例,展示了Hashing.consistentHash()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。Hashing.consistentHash()方法的具体详情如下:包路径...
java实现 guava里头有个现成的实现 guava-22.0-sources.jar!/com/google/common/hash/Hashing.java /** * Assigns to {@code hashCode} a "bucket" in the range {@code [0, buckets)}, in a uniform manner * that minimizes the need for remapping as {@code buckets} grows. That is, {@code ...

In this section, we are going to talk about the error tolerance and scalability in a consistent hashing algorithm. Suppose that Server 3 is down, as the figure shows below: We’ll find that the data object A, B, and C are still available. At this time, the data object D will be lo...
jump consistent hash是一致性哈希的一种实现,论文见A Fast, Minimal Memory, Consistent Hash Algorithm 经典的一致性哈希算法来自Consistent Hashing and Random Trees: Distributed Caching Protocols for Relieving Hot Spots on the World Wide Web jump consistent hash与之的主要区别是节点可以扩容,但是不会移除节点...
