MySQL replication is a cornerstone of modern database infrastructure, enabling real-time data duplication from a primary (source) server to one or more replicas (slaves). This capability is essential for database administrators looking to achieve high availability, disaster recovery, scalable read performance, and geographically distributed deployments.
For database professionals, mastering replication ensures minimal downtime, efficient load balancing, and seamless maintenance operations.
MySQL supports several replication modes, including asynchronous, semi-synchronous, and group replication, allowing flexible architecture based on business needs. Replication works by logging changes on the source server (binary logs) and applying them to replicas using relay logs and SQL threads. Common use cases include read/write splitting, hot standby failovers, and data analytics on replicas without affecting production performance.
Some frequent issues include replication lag, GTID-related errors, and data inconsistencies during failover or network interruptions. Blogs under this tag offer actionable solutions such as GTID-based replication setup, monitoring with tools like Percona and ProxySQL, and best practices for replication recovery and failover management.
