If you mean that you are using Schema Loader to generate DBIC result classes from the live schema of the database, then I'm pretty sure your bug lies in DBIx::Class::Schema::Loader::DBI. In particular, all the things that happen in ::Schema::Loader::DBI::mysql will not be happening with mariadb. You could just copy/paste that class into your local project lib dir and rename to miriadb and see if it fixes things.
