DATABASE DUPLEXING METHOD FOR EFFICIENT SERVER LOAD DISTRIBUTION WHEN PROCESSING LARGE AMOUNTS OF DATA AND APPARATUS THEREOF

摘要

A method performed by an apparatus including a plurality of databases (database, DB), comprising: distributing acquired data to generate first data and second data; storing the first data in a first master DB of the first replica set; the first master DB duplicates the first data and transmits it to a first slave DB of the first replica set; the first slave DB stores the first data; loading the first data from the first slave DB; store the second data in a second master DB of the second replica set; the second master DB duplicates the second data and transmits it to a second slave DB of the second replica set; the second slave DB stores the second data; and loading the duplicated second data from the second slave DB, wherein the first replica set includes the first master DB, the first slave DB, and a first manager, and the second replica The set includes the second master DB, the second slave DB, and a second manager, wherein the first manager is formed in the same server as the second master DB or the second slave DB, and includes the first replica set; The second replica set is configured to be complementary, or the second manager is formed in the same server as the first master DB or the first slave DB so that the first replica set and the second replica set are complementary A method of being configured may be provided.
