MySQL InnoDB Cluster is an Oracle High Availability solution that can be easily installed over MySQL to provide high availability with multi-master capabilities and automatic failover. In the previous post, we presented the first component of InnoDB Cluster, group replication. Now, we will go through the second component, MySQL Router. We will address MySQL Shell in a final installment of this three-part series. By then, you should have a good overview of the features offered by MySQL InnoDB Cluster.
MySQL Router
This component is responsible for distributing the traffic between members of the cluster. It is a proxy-like solution to hide cluster topology from applications so applications don't need to know which member of a cluster is the primary node and which are secondaries.
