#
# InnoDB is different from MyISAM in that it uses a text file
# with an '.isl' extension instead of a symbolic link so that
# the tablespace can be re-located on any OS. Also, instead of
# putting the file directly into the DATA DIRECTORY,
# it adds a folder under it with the name of the database.
# Since strict mode is off, InnoDB ignores the INDEX DIRECTORY
# and it is no longer part of the definition.
