mysqldump with --no-tablespaces on InnoDB with index?
&quot;Tablespaces&quot; are for clumping tables into a single .ibd.  The mysqldump options relating to that control whether to output the DDL statements such as CREATE TABLESPACE.
mysqldump does not dump the contents of indexes, regardless of Engine.  It does dump the definitions of the indexes.  When reloading, the indexes will be recreated.  Yes, MyISAM has a separate file for indexes while InnoDB includes the indexes in the same &quot;tablespace&quot; file; but the locations of indexes is an implementation detail that does not matter when dumping and reloading tables.
If you have not explicitly created any &quot;tablespaces&quot;, ignore options relating to them.  (Very few people use tablespaces.)
