In the event of an unexpected failure, MySQL Router detects this and forwards client applications to the new primary.įor this demonstration, we have already configured 3 MySql Instances. You can also configure MySQL Router can automatically configure itself based on the cluster you deploy, connecting client applications transparently to the server instances. If the primary fails, a secondary is automatically promoted to the role of primary. Multiple secondary server instances are replicas of the primary. In the default single-primary mode, an InnoDB Cluster has a single read-write server instance – the primary. In the event of an unexpected failure of a server instance the cluster reconfigures automatically. AdminAPI removes the need to work directly with Group Replication in InnoDB Clusters. Each MySQL server instance runs MySQL Group Replication, which provides the mechanism to replicate data within InnoDB Clusters, with built-in failover. By using the AdminAPI included with MySql Shell, you can easily configure and administer a group of at least three MySQL server instances to function as an InnoDB Cluster. MySQL InnoDB Cluster provides a complete high availability solution for MySQL.
