Are there any pitfalls / things you need to know when changing from MyISAM to InnoDB

Question

One of my projects use the MyISAM engine in MySQL, but I\'m considering changing it to InnoDB as I need transaction support here and there.

Answer 1

There is one big caveat. If you get any kind of hardware failure (or similar) during a write, InnoDB will corrupt tables.

MyISAM will also, but a mysqlcheck --auto-repair will repair them. Trying this with InnoDB tables will fail. Yes, this is from experience.

This means you need to have a good regular data backup plan to use InnoDB.
