This package is currently empty.
The only thing it does, is that it pulls in correct dependencies of mariadb package
This is because in Fedora<=27 there were dependency issues, which lead to some package being non-installable.
The fully functional package is present in F28 and later. It provides part fo the functionality of mariadb, which also has been updated to not conflict with the connector.
Please, in F<=27 use mariadb instead. In F>=28 use this package.
