Hi Sergey, for debian we are using some virtual packages (e.g. default-mysql-client) which then depends on the actual DB, usually MariaDB. https://packages.debian.org/bullseye/default-mysql-client Not sure if there is a similar way in CentOS. If MariaDB is default now in CentOS 9 for example and MySQL is only provided from another external repository, it certainly make sense to use the default MariaDB.

Should we switch from MySQL lib usage to MariaDB lib usage?
