MariaDB support

Development

Actually for the MySQL versions we want to support now that we support MariaDB I see 2 main options:

  1. Support the MySQL versions for which MariaDB is a drop-in replacement.

For example today we want to support MariaDB 10.1 and 10.3 (see Debian -- Package Search Results -- mariadb-server).

Based on that and on MariaDB versus MySQL - Compatibility - MariaDB Knowledge Base, it would mean supporting MySQL 5.6 and 5.7.

However as mentioned on MariaDB versus MySQL - Compatibility - MariaDB Knowledge Base the differences between MySQL and MariaDB are increasing at each version so this strategy will work less and less.

  1. Define our MySQL support not based on what’s avail in Debian but on a specific rule such as: we support the latest GA of MySQL (which is MySQL 8.0.20 today, see https://dev.mysql.com/downloads/mysql/).

If we want to be even nicer, we could say that we support the last 2 GAs but that feels a lot to me. The previous GA is currently 5.7.30.

WDYT?

Thanks
