查询词典 database access

In the algorithm, there is no master site that objects address computations must go through or access to a centralized directory. All compute nodes and storage nodes calculate node address independently, the objects access and storage nodes change never require atomic updates to multiple clients. The compute nodes adapt to the change of storage nodes by client image adjustment algorithm.

该算法使得数据对象分配地址的计算不依赖于中央节点计算或者访问一个集中式目录，所有计算节点和存储节点独立地进行地址计算，并且对数据对象的访问操作或新增节点引起的系统规模变化不需要原子更新到其他计算节点，计算节点通过视图校正算法自主学习，自动适应新的系统规模。
