Use HashMap Withstd::unordered_mapin C++ std::unordered_mapis implemented using the hash table in C++. Hash tables also belong toassociative containers. The mapped values are stored in a hash table in an array of buckets or slots, from which necessary values can be retrieved. ...
通过使用并发的 SSE2 指令,这些 hashmap 可以允许一次并发查找 16 个槽位,即使当 hashmap 的填充率已经达到 87.5% ,也可以保持快速。 重要:本仓库借鉴了abseil-cpp仓库的代码, 做了修改,并且可能和原版本行为不同。本仓库是独立工作,像其他开源项目一样不提供保证。请访问abseil-cpp获取官方的 Abseil 库。 安装...

In contrast, in most traditional hash tables, a change in the number of array slots causes nearly all keys to be remapped because the mapping between the keys and the slots is defined by a modular operation. 大概意思就是“一致性哈希是一种特殊的哈希算法,提供了这样的一个哈希表,当重新调整...

the value 9 comes fromsizeof(void *) + 1, as thenodehash maps store one pointer plus one byte of metadata for each entry in the bucket array. flat tables store the values, plus one byte of metadata per value), directly into the bucket array, hence thesizeof(C::value_type) + 1....
