Mysql changing table engine MyISAM to InnoDB

innodb, myisam, mysql

Solution

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.

Problem

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) visitors can't get into the site The table engine is MyISAM and I want to change it to InnoDB I have few questions: - How can I change the table engine without stoping my site from working - There is a way to optimize InnoDB table without locking it
