Up until version 10.1, MariaDB used Percona XtraDB in place of InnoDB as the default storage engine. As of MariaDB 10.2, InnoDB is the default again.[1]
XtraDB incorporates InnoDB's ACID-compliant design and MVCC architecture, and allows for a greater degree of tuning and scalability.[2] The engine is also better suited to multi-core processing, which addresses some of the issues known to InnoDB.[3]
