MySQL 5.7 Release Notes
Oracle recommends InnoDB as the preferred
storage engine for typical database applications, from single-user
wikis and blogs running on a local system, to high-end
applications pushing the limits of performance. In MySQL
5.7, InnoDB is the default storage
engine for new tables.
Important
InnoDB cannot be disabled. The
--skip-innodb
option is deprecated and has no effect, and its use results in a
warning. Expect it to be removed in a future MySQL release. This
also applies to its synonyms (--innodb=OFF,
--disable-innodb, and so forth).
