Andrii Nikitin (Inactive) added a comment - 2017-06-06 07:58 Yes, that is the point. The page https://mariadb.com/kb/en/mariadb/create-tablespace says 'command is only used in MySQL Cluster' , which is not true anymore since 5.7 . So probably we should explicitly confirm that MariaDB doesn't support the command in InnoDB as well.
