Cuckoo Hashing 的引入 在indexlib的底层,需要一个高性能的Key/Value引擎来提供类似python Dict/ Java HashMap/ C++ unordered map(这些数据结构的性能不能接受)的支持。最基本的就是支持insert(key, value)和find(key)这两种操作。原本我们有Dense Hash Table和Chain Has
我们先来看看cuckoo hashing有什么特点,它的哈希函数是成对的(具体的实现可以根据需求设计),每一个元素都是两个,分别映射到两个位置,一个是记录的位置,另一个是 备用位置。这个备用位置是处理碰撞时用的,这就要说到cuckoo这个名词的典故了,中文名叫布谷鸟,这种鸟有一种即狡猾又贪婪的习性,它不肯自己筑巢, 而是...

Cuckoo filters provide similar space and time complexity with less hashing overhead than bloom filters (because cuckoo filters only have 2 hash functions and bloom filters have k number of functions). However, the main advantage is that cuckoo filters can delete items from the membership set becau...
