| 摘 要： | 从数据库的观点看，在执行单一查询前进行复制数据集是容易实现的，但查询处理器指派一次查询给那些没有充分操作和存储合适副本的结点时，从而引起在同步机制中副本快照经常过时和副本定位时带来昂贵的网络开销。本文将讨论一种在全局数据网格中多个结点的非一致性及快照管理的量化分析方法。

| Abstract: | From a database perspective it is advisable to replicate data sets at different nodes in the data grid before executing a single query,but the query processor assigns a query to those nodes,which do not operate at full capacity and which have not stored the appropriate replica.Therefore,the replica may usually lead to outdated replica snapshot in a synchronization mechanism and bring out expensive network overhead in locating replica.The paper focuses on the quantification of the inconsistency and the snapshot management at non-individual members of a global data grid. |
