Using InnoDB Instead of XtraDB

By default MariaDB 10.1 and earlier releases come compiled with XtraDB as the default InnoDB replacement. From MariaDB 10.2, InnoDB is the default.

MariaDB starting with 5.5

Starting from MariaDB 5.5, all standard MariaDB distributions also includes InnoDB as a plugin.

To use the InnoDB plugin instead of XtraDB you can add to your my.cnf file:

[mysqld]
ignore_builtin_innodb
plugin_load=ha_innodb.so
# The following should not be needed if you are using a mariadb package:
plugin_dir=/usr/local/mysql/lib/mysql/plugin

MariaDB until 5.3

For MariaDB 5.3 and below, the name of the library is ha_innodb_plugin.so

The reasons you may want to use InnoDB instead of XtraDB are:

You want to benchmark the difference between InnoDB/XtraDB
You hit a bug in XtraDB
You got a table space crash in XtraDB and recovery doesn't work. In some cases InnoDB may do a better job to recover data.
