You can use MySQL Router 8.0.19 and later to bootstrap against an
InnoDB ReplicaSet. For more information, see
Section 6.10, “Using MySQL Router with AdminAPI, InnoDB Cluster, and
InnoDB ReplicaSet”. The only
difference in the generated MySQL Router configuration file is the
addition of the
option. When MySQL Router is bootstrapped against a ReplicaSet, the
generated configuration file includes:
When you use MySQL Router with InnoDB ReplicaSet, be aware that:
The read-write port of MySQL Router directs client connections to the primary instance of the ReplicaSet.
The read-only port of MySQL Router direct client connections to a secondary instance of the ReplicaSet, although it could also direct them to the primary.
MySQL Router obtains information about the ReplicaSet's topology from the primary instance.
MySQL Router automatically recovers when the primary instance becomes unavailable and a different instance is promoted.
You work with the MySQL Router instances which have been
bootstrapped against a ReplicaSet in the same way as with
InnoDB Cluster. For more information on
see Section 6.10.6, “Working with a Cluster's Routers” .
