wikipedia:InnoDB is a storage engine for the database management system MySQL and MariaDB. Is the default engine since MariaDB 10.2 (2016).
InnoDB supports:
- Both SQL and XA transactions
- Tablespaces
- Foreign keys
- Full text search indexes, since MySQL 5.6 (February 2013) and MariaDB 10.0)
- Spatial operations, following the OpenGIS standard
- Virtual columns, in MariaDB
- Page compression [1]
