Overview

The Database Replication Cluster project utilized MySQL Galera to establish a fault-tolerant, multi-master replication environment. The architecture consisted of three master database nodes, each dedicated to handling requests from a specific branch office while maintaining real-time synchronization across the cluster. This setup ensured uninterrupted operations even in the event of a node failure, providing both high availability and improved performance through distributed load handling.

Key Features

  1. Three-Master Cluster Architecture – Configured three master nodes to operate in a synchronized Galera cluster, enabling read and write operations from any node.

  2. Branch Office Load Segmentation – Assigned each master node to manage transactions from a dedicated branch office, reducing latency and improving response times.

  3. Performance Optimization – Fine-tuned MySQL configurations and Galera parameters for faster replication, reduced conflict handling, and improved query performance.

This MySQL Galera-based multi-master replication setup provided a resilient and scalable database infrastructure capable of supporting multiple branch offices with minimal downtime and optimal performance. The solution ensures data consistency, reduces latency, and delivers enterprise-grade reliability across distributed locations.
