Cluster data management system and method for data restoration using shared redo log in cluster data management system

Abstract

Provided are a cluster data management system and a method for data restoration using a shared redo log in the cluster data management system. The data restoration method includes collecting service information of a partition served by a failed partition server, dividing redo log files written by the partition server by columns of a table including the partition, restoring data of the partition on the basis of the collected service information and log records of the divided redo log files, and selecting a new partition server that will serve the data-restored partition, and allocating the partition to the selected partition server.
