Hi, I was wondering if mariadb plans to overcome mysqls limitations such as - foreign key operations do not start triggers - triggers can’t be recursive (error 1442) I know that mariadb wants to be compatible with mysql but maybe these features could be optional? The mysql/mariadb comparison shows additional features which wont break compatibility I guess because they don’t exist in mysql (yet?). But besides additional features, is there a chance that mariadb could ever overcome limitations? Is this even a goal of this project? So far I only found postgres to support these features. Background of this question: I am developing an object relational mapper and my goal is to have the database enforce the consistency. So triggers and foreign key constraints working together are vital for this. regards Ludwig
