MariaDB Enterprise Platform has integrated MariaDB Cluster (also known as Galera Cluster) since the 10.0 releases. MariaDB Cluster is a synchronous multi-primary (multi-master) replication solution, that has automatic node provisioning, with parallel replication, no secondary lag, with built-in automatic conflict detection and handling, plus components to allow load balancing.
So where does MariaDB Cluster stand out compared to the rest? Here are a few selected features that may pique your interest:
* Galera 4 is standard in MariaDB Cluster since MariaDB Server 10.4.
* The mysql database contains new tables: wsrep_cluster, wsrep_cluster_members, wsrep_streaming_log, and wsrep_allowlist.
* Streaming replication allows replicating transactions of an unlimited size, i.e. greater than 2GB.
* GTID handling with MariaDB Cluster and MariaDB Server are synchronised, thus you have seamless replication of MariaDB GTIDs to other nodes in the cluster.
* wsrep_mode to help you replicate MyISAM, and Aria storage engines.
* You can migrate from unencrypted replication to TLS Galera communications without any downtime.
* A JSON interface for wsrep node state, including progress logging for State Snapshot Transfers (SSTs). This also includes the IP allowlist for Galera Cluster nodes that can make the requests.
* Rolling upgrades from MariaDB Server 10.4 to later, are supported.
