EH＊g：一个高可用的可扩展分布式数据结构

EH＊g是一个高可用性的可扩展分布式数据结构。利用记录组技术增加系统的可利用性，并对每条要求插入的记录，在主文件和奇偶文件两个地方进行插入。当主文件中的记录发生丢失或破坏时，可利用同一记录组中其它记录的信息和保存在奇偶文件中的信息来恢复该记录，以此达到高可用性。

EH*g: A High-Available Scalable Distributed Data Structure

EH*g is a high-available scalable distributed data structure. To add the availability of a system,the technique of record grouping is adopted. Every record which requires to insert must insert in a primary file and in a parity file .When a record is lost or destroyed in the primary file ,the record can be restored using the information of other records in the record group and the information that is saved in the parity file to win high availability.
