About MariaDB Galera Cluster

MariaDB Galera Cluster is made for today’s cloud based environments. It is fully read-write scalable, comes with synchronous replication, allows multi-master topologies, and guarantees no lag or lost transactions. Some of its features & benefits are listed below.

Features

  • Synchronous replication
  • Active-active multi-master topology
  • Read and write to any cluster node
  • Automatic membership control, with failed nodes dropped from the cluster
  • Automatic node joining
  • True row-level parallel replication
  • Direct client connections, native MariaDB/MySQL look & feel

Benefits

The above features yield several benefits for a database clustering solution, including:

  • No slave lag
  • No lost transactions
  • Both read and write scalability
  • Smaller client latencies

Technology

MariaDB Galera Cluster uses the Galera library for the replication implementation. To interface with Galera replication, we have enhanced MariaDB to support the replication API definition in the Write Set REPlication (wsrep API) project. The implementation of the replication API in MariaDB happens in the open source MySQL-wsrep project.

User Feedback plugin

MariaDB Galera Cluster includes a User Feedback plugin. This plugin is disabled by default. If enabled, it submits basic, completely anonymous usage information. This information is used by the developers to track trends in usage to better guide development efforts. If you would like to help make MariaDB Galera Cluster better, please add “feedback=ON” to your my.cnf file! See the User Feedback Plugin page for more information.

Quality

The project always strives for quality, but in reality, nothing is perfect. Please take time to report any issues you encounter at: http://mariadb.org/jira. We hope you enjoy MariaDB Galera Cluster!

Operations Support
