This time, I will introduce partitioning and high availability cluster (HaProxy) in MariaDB.

There are several ways to sustain a large system.

It is about partitioning techniques and clusters.

I would like to introduce the principle that a large-capacity system is supported through several methods.

The figure below is for a load balancer that distributes large-capacity systems.

It was introduced for the project called table partitioning and high principles and structure of MariaDB HAProxy the availability of one of the cluster load balancer.
