MySQL 5.6 Reference Manual  /  The InnoDB Storage Engine  /  InnoDB File-Format Management

14.10 InnoDB File-Format Management

As InnoDB evolves, data file formats that are not compatible with prior versions of InnoDB are sometimes required to support new features. To help manage compatibility in upgrade and downgrade situations, and systems that run different versions of MySQL, InnoDB uses named file formats. InnoDB currently supports two named file formats, Antelope and Barracuda.

This section discusses enabling InnoDB file formats, verifying compatibility of different file formats between MySQL releases, identifying the file format in use, and downgrading the file format.
