Percona XtraDB FAQ

A: eXtra performance, eXtra scalability, eXtra features.

A: We distribute the storage engine under **GPLv2** license, and it is absolutely free to use. No dual-licensing. No community and enterprise separation.

A: No, if they are currently using InnoDB. The XtraDB plugin is designed to be used instead of InnoDB, and is fully compatible with your existing InnoDB tables and server settings. To create new tables you still use CREATE TABLE … ENGINE=InnoDB. If your tables currently use a non-InnoDB storage engine such as MyISAM, then you will have to convert them to XtraDB with ALTER TABLE <table> ENGINE=InnoDB.

A: Install Percona Server with XtraDB. It's included.

A: uninstall is the exactly the same as for InnoDB plugin

A: Just uninstall XtraDB and use the InnoDB plugin instead. You don't need to convert any of your data files, modify any settings, or make any other changes. If you want to revert back to the version of InnoDB that is shipped with the official MySQL builds (e.g. not the InnoDB plugin) then you can use the InnoDB plugin's downgrade procedure.
