This article discusses creating a high-performance database server system that ensures data availability. The researchers aimed to build a reliable system using a cluster of database servers, called a MariaDB Galera Cluster. In this setup, if one server fails, another server acts as a backup, ensuring continuous access to the system without data loss. By replicating data in real time across servers, the system maintains data synchronization and high availability for users. Their approach supports multi-master database replication, resulting in a dependable and fast-performing system that reduces the risk of system downtime and data loss.
