Summary of research on hash table and hash functionWith the increasing of information level, the data has been replaced computing as the center of Information Computing, the demand for storage has been increasing the volume of explosive growth trend,

Memcache is a distributed cache system, but it does not provide clustering capabilities, which can easily become a bottleneck in large-scale applications. However, the client can be freely extended at this time and implemented in two phases. First
