Technical notes

Compatibility with legacy charms

• New MySQL charm is a juju-interface compatible replacement for legacy charms such as “MariaDB ”, “OSM MariaDB ”, “Percona Cluster ” and “Mysql Innodb Cluster ” (using legacy interface “mysql”, via endpoints “mysql” and “mysql-root”). Other legacy interfaces such as “mysql-router ” interface (“db-router” endpoint) and “mysql-shared ” interface (“shared-db” endpoint) are also supported. However, it is highly recommended to migrate to the modern interface ‘mysql_client ’. It can be easily done using the charms library ‘data_interfaces ’ from ‘data-platform-libs ’.

Please contact us, see details below, if you are considering migrating from other “legacy” charms not mentioned above. Additionally:

• Tracks description:

  • Charm MySQL K8s charm follows the SNAP track “8.0” (through repacked ROCK/OCI image).

• No “latest” track in use (no surprises in tracking “latest/stable”)!

  • Charmed MySQL K8s charms provide legacy charm through “latest/stable”.

• Charm lifecycle flowchart diagrams: MySQL .

• Modern interfaces are well described in “Interfaces catalogue ” and implemented by ‘data-platform-libs ’.
