How to setup MaxScale with MariaDB Galera Cluster

This post is just following up my previous blog post which describes how to setup 3-nodes MariaDB Galera Cluster with MySQL-Sandbox on single server.

 

Today, I’ll try to explain how we can setup MariaDB MaxScale over the Galera Cluster. Before I move ahead, I would like to explain about MaxScale little bit.

MariaDB MaxScale is a database proxy that enables horizontal database scaling while maintaining a fast response to client applications. You can implement MaxScale on either MySQL Replication or Galera cluster. With MySQL Replication, you can either use Read/Write Splitting or Connection routing and same with Galera Cluster. You can get more information here about this product.

Seppo  Jaakola, Codership CEO

Data inconsistency is the worst problem that can happen for a synchronous database cluster. At some point it will appear during replication processing, simply because the application of replication events is not possible in some cluster nodes due to missing rows, excessive rows or wrong values in the row columns. As a result, this usually stops the replication process ...READ MORE
