Hi Ansgar,
We just found out that when exporting a database with views, the exporter created temporary tables using MyISAM, which is not supported by Mariadb (at least, not the version I use in our dockers). I don't know if this is a MysqlDump issue or something in your code.
Our workaround of course was not exporting the views (not a problem in this case). But maybe this is something you want to know.
Kinds regards, Jelmer
