via “galera cluster replication with multi-master synchronous consistency”
MariaDB server is a community developed fork of MySQL server. Started by core members of the original MySQL team, MariaDB actively works with outside developers to deliver the most featureful, stable, and sanely licensed open SQL server in the industry.
Unique: Implements synchronous multi-master replication via write set certification, where conflicts are detected deterministically without a central arbiter. Uses a gossip protocol for cluster membership management and automatic node discovery, unlike traditional MySQL replication's master-slave topology.
vs others: Stronger consistency than asynchronous MySQL replication; simpler than distributed consensus (Raft, Paxos) but with higher latency overhead; better for multi-master scenarios than PostgreSQL's logical replication
