This MySQL router charm provides a MySQL 8 Router for Windows. It proxies database requests from an application to a MySQL 8 InnoDB cluster.
It is a subordinate charm that is used in conjunction with the mysql-innodb-cluster charm. Starting with Ubuntu Focal, the percona-cluster is no longer available, meaning you will need to use MySQL router to integrate with any application that requires the shared-db relation with MySQL.
This is a subordinate charm that provides shared-db, and consumes mysql-router. Your charm does not need any changes to work with this charm. You simply need to deploy it and add the shared-db relation as you normally would.
juju deploy ./mysql-router
juju add-relation mysql-innodb-cluster:db-router mysql-router:db-router
juju add-relation your-charm:shared-db mysql-router:shared-db
