    摘要: The present invention provides a recovery method using extendible hashing-based cluster logs in a shared-nothing spatial database cluster, which eliminates the duplication of cluster logs required for cluster recovery in a shared-nothing database cluster, so that recovery time is decreased, thus allowing the shared-nothing spatial database cluster system to continuously provide stable service. In the recovery method, if a failure occurs in a predetermined node, a second node in a group, including the node, records cluster logs in main memory on the basis of extendible hashing. If the node that has failed recovers itself using a local log, the second node in the group transmits cluster logs in packets to a recovery node that is the failed node. If the recovery node reflects the received cluster logs and maintains consistency with other nodes in the group, the recovery node resumes normal service.

    摘要翻译: 本发明提供了一种在无共享空间数据库集群中使用可扩展散列集群日志的恢复方法,其消除了在无共享数据库集群中集群恢复所需的集群日志的重复,从而减少了恢复时间 使无共享的空间数据库集群系统不断提供稳定的服务。 在恢复方法中,如果在预定节点中发生故障,则包括该节点在内的组中的第二节点基于可扩展哈希在主存储器中记录集群日志。 如果失败的节点使用本地日志恢复自身,则该组中的第二个节点将分组中的群集日志传输到作为故障节点的恢复节点。 如果恢复节点反映接收的群集日志并维护与组中其他节点的一致性,则恢复节点恢复正常服务。
