摘要
提出了一种在数据网格环境下的基于区域性分割索引节点的分布式副本定位方法。利用将副本定位索引信息按着区域特点或访问的频繁程度分布存储在多个索引节点上,同时利用本地副本定位节点完成本地副本的查询。此方法实现简单且具有区域特性。
A new decentralized replica location method based on locality in data grid is proposed. In this method replica location index nodes are partitioned by domain name or similar and replica location index information are spread on them . Meanwhile it employs replica location nodes to support local query for local replicas. It can achieve good locality and ease of implementation.
