Mysql changing table engine MyISAM to InnoDB

Question

On my site I have a visitor\'s table with 10 million rows.
Every request to the site inserts row to the table, in case the table is locked (usually in optimize query) v

Answer 1

The easiest way is

ALTER TABLE table_name ENGINE = InnoDB;

If you use InnoDB engine you should not worry about locking tables, because this engine locks data by rows.
