Hi What is the reason for the the new enforce_storage_engine option being session only? Percona's implementation is global, and I realise there was a request to make it less strict, and be overridden by session for users with the super privilege, but surely it would make sense to allow a global default to be set, rather than just session only? The notes say that it was implemented based on default_storage_engine, but that variable is global and session, not just session. ian
