Recently, I stumbled upon an intriguing website showcasing numerous web cameras operated by the Japanese government. Surprisingly, these cameras offer live feeds by refreshing a single image every 0.1 seconds. Initially, I thought this was a sign of governmental inefficiency or outdated IT infrastructure in Japan. However, upon further

What's Consistent Hashing First, let me quote a definition from Wikipedia: In computer science, consistent hashing is a special kind of hashing technique such that when a hash table is resized, only 𝑛/𝑚 keys need to be remapped on average where 𝑛 is the number of keys and 𝑚 is the

分布式基石算法1: 一致性hash. 什么是 一致性hash 算法 首先摘抄一段维基百科的定义 一致哈希 是一种特殊的哈希算法。在使用一致哈希算法后，哈希表槽位数（大小）的改变平均只需要对𝐾/𝑛 个关键字重新映射，其中 𝐾 是关键字的数量，𝑛是槽位数量。然而在传统的哈希表中，添加或删除一个槽位的几乎需要对所有。
