MariaDB MaxScale — 5 use cases for database load balancing and routing

MaxScale sits between your application and your MariaDB servers and acts as an intelligent proxy. It can route queries to different backends, balance load across replicas, handle failover and pool connections — all without changing a line of application code. It is developed by MariaDB Corporation and is tightly integrated with MariaDB's replication and clustering features. But understanding what it can actually do for you requires looking at the specific problems it solves, not just the feature list. Here are five real use cases where MaxScale earns its place in a production setup. What MaxScale is and how it works MaxScale is a database proxy daemon. It listens on a TCP port, accepts connections from clients, and forwards queries to one or more backend MariaDB servers based on routing rules you define. The routing logic is handled by modules called routers. Each router implements a different strategy. You define which router to use in the MaxScale configuration file ( maxscale.cnf ),
