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.
