分布式数据缓存系统的设计与实现

In the modern Internet Applications of Enterprise, Distributed Data Caching Technology plays an important role in the system architecture. It can reduce the load of database access layer and improve overall system performance. Because of the shortage of existing distributed caching products in data redundancy backup and failure recovery, this paper design and implement a Distributed Data Caching System, which has the function of data redundancy backup and failure recovery. This system uses the Peer-To-Peer topology, achieves two caches of different data distribution patterns, replicated cache and distributed cache, uses JGroups technology to achieve communication and data migration between cluster nodes, and completes the data redundancy backup and failure recovery depending on reliable service module. In the test, Distributed Data Caching System the paper designed provides reliable data redundancy backup and failure recovery mechanisms, and the system is stable.
