Deploying High-Availability Multi-Master MySQL NDB Clusters with MySQL Cluster Manager
Traditional MySQL replication architectures (active-passive or source-replica topologies) introduce replication lag and require failover orchestrators (e.g., Orchestrator or ProxySQL) to handle master crashes. MySQL NDB Cluster is a shared-nothing, distributed database that provides real-time in-memory performance, 99.999% high availability, and active-active multi-master read/write capabilities across all SQL nodes. This guide details configuring and scaling a multi-master NDB cluster using Oracle MySQL Cluster Manager (MCM). Core Architecture & Node Roles An NDB cluster consists of three distinct node types: ...
