Code Distributed Hash Table based MapReduce System and Method

摘要

According to the present invention, in a map distributed system based on a code distributed hash table, data is managed by a ring structure of a file system hierarchy based on a code distributed hash table and a dual hierarchical ring structure of an in-memory cache hierarchy, After predicting the probability distribution of access requests, load balancing is possible by scheduling the task by adjusting the hash key range of the code distributed hash table of the in-memory cache hierarchy based on the predicted probability distribution and increasing the cache hit rate have.
