Compare the MariaDB Galera and MariaDB Helm charts
Improve this page by contributing to our documentation.
There are two different ways to deploy a MariaDB cluster, using the MariaDB Helm chart or the MariaDB Galera Helm chart. Both solutions provide a simply and reliable way to run MariaDB in a production environment. Keep reading to discover the differences between them and check which one better suits your needs.
- The MariaDB Galera Helm chart configures a cluster with three nodes by default, all of them acting as master nodes with writing / reading permissions. The MariaDB Helm chart deploys one node that you can use as a single-node application database.
- The MariaDB Galera Helm chart provides a cluster with both read and write scalability since all nodes acts as master nodes (multi-master topology) while a cluster comprised of several MariaDB nodes will establish the master-slave topology.
- The MariaDB Galera Helm chart deploys a cluster with synchronous replication, avoiding data loss if any node fails.
- The MariaDB Galera Helm chart cluster ensures high-availability thanks to automatic membership control, failed nodes are drop from the cluster.
The following diagram shows you the options you have for using Bitnami’s MariaDB solutions in your deployments: either as a single-node database (MariaDB) or as a multi-master cluster (MariaDB Galera).
