1. 确认ngx_murmur_hash2函数在src/core/ngx_murmurhash.c中的具体实现 ngx_murmur_hash2函数是Nginx源码中用于计算哈希值的函数,通常基于MurmurHash2算法实现。在Nginx的源码中,该函数的具体实现可能因Nginx版本而异,但基本原理相似。以下是一个典型的ngx_murmur_hash2函数实现示例: c uint32_t ngx_murmur_hash2...
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...
