How do you specify the Fill Factor when creating an index in MySql?
回答1:
You don't.
http://dev.mysql.com/doc/refman/5.0/en/create-index.html
However, it is an 'accepted' feature request for version 6.x: http://bugs.mysql.com/bug.php?id=18178
So, don't hold your breath on seeing it any time soon.

Assuming that you are using InnoDB, it seems like this is only supported at database level, not index level.
The setting is called innodb_fill_factor and defaults to 100 see
https://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_fill_factor for more details.
