Question
How do I convert MySQL to Barracuda File Format?
Answer
You can change the default file format from within your /etc/my.cnf configuration file by adding or modifying the following line:
innodb_file_format=Barracuda
Once done, the changes should only apply to new tables, and should not erase existing databases or tables. However, it is still recommended to take a full MySQL backup beforehand to be on the safe side.
