MySQL's high-availability, multi-master, replication clustering solution for the InnoDB storage engine with automatic failover

MySQL InnoDB Cluster was released (GA) on April 12, 2017. It consists of three components:

  • MySQL Server (5.7+) with group replication
  • MySQL Shell (1.0+)
  • MySQL Router (2.1+) which is a database proxy

As with Galera cluster, only the InnoDB storage engine is supported. (And hence the name: InnoDB Cluster.) One difference from Galera is that it's not recommended to have geo-distributed nodes in InnoDB Cluster. (See Group Replication Limitations.)

Contrast: Galera, MySQL NDB Cluster
