MaxScale

MariaDB 11.4 can provide improvements without MaxScale. MaxScale abstracts all routing and failover logic into a single software layer without requiring application-level changes. MaxScale improves scaling through query routing, load balancing, and failover automation. MaxScale can be used across deployments ranging from startup environments to enterprise-grade distributed database clusters. MaxScale is a proxy layer that sits between application servers and MariaDB database instances. MaxScale is applicable to any MariaDB deployment requiring high availability, horizontal read scaling, or resilience to node failures. Pairing MariaDB 11.4 with MaxScale supports a database farm architecture for more extreme workloads.
