ngx_murmur_hash2函数位于Nginx源码的src/core/ngx_murmurhash.c文件中。它是Nginx中用于计算哈希值的一个关键函数。 函数实现细节: ngx_murmur_hash2函数实现了MurmurHash2算法。这个算法是一种非加密哈希函数,特点是速度快且哈希分布良好。以下是一个简化的代码示例,展示了ngx_murmur_hash2函数的基本结构: c uint...

算法原理可参考维基百科: https://zh.wikipedia.org/wiki/Murmur%E5%93%88%E5%B8%8C Scala API自身是有MurmurHash算法的实现的( scala.util.hashing.MurmurHash3 ),返回值是int,32位。spark也广泛采用了Murmur哈希算法,可以看一个在sparksql中的例子,在TreeNode类中有:之所以调用 productHash ...

Just compile and link your program withmurmur3.c, and be sure to includemurmur3.hto get the function prototypes. There are three hash functions: void MurmurHash3_x86_32 (const void *key, int len, uint32_t seed, void *out); void MurmurHash3_x86_128(const void *key, int len, uint32...

murmuris a pure Java implementation of all Murmur hashes, namely, Murmur1, Murmur2 and Murmur3. The library is a direct Java implementation of the C++ source code. Hash generation has been 100% unit tested against the hashes generated using the C++ code. The library should help in building...
