Method and system for managing replication of data
Data replication management which enables rapid retrieval while increasing the performance of the entire system, and maintaining data synchronization regarding successively updated data is performed. There are steps which comprises a step that when a slave node which has received an instruction for retrieval does not receive a return massage from a master node within a predetermined time period (Ts1) from the transmission of a request message to the master node, the slave node requests the master node to provide a transaction log up to the latest version with respect to the update of a master database; a step that the master node which has received the request transmits the transaction log to the slave node; and a step that the slave node updates a replica database with reference to the transaction log transferred from the master node.
