I would like to see model export to MariaDB, but currently we have no resources available for such an extension. I don't even know how to begin to write an insert trigger in MariaDB, so the best way to get this functionality quickly is if we get some help :)
There are a few caveats with MariaDB, which I tried to sort out with Monty et al. about a year ago, but as I understand it they have been focusing on other requirements (from a big client). I don't know where they are at with those right now.
1. Parametrized views and/or table valued functions
2. More than 63 joins in a view
3. Clustered indexes
4. Table elimination on foreign keys
5. Indexing sort order (asc, desc)
6. JOIN FIRST or LEAD/LAG or KEEP with DENSE_RANK
Ordered by priority.
