MariaDB features not supported by Amazon RDS

The following MariaDB features are not supported on Amazon RDS:

  • S3 storage engine

  • Authentication plugin – GSSAPI

  • Authentication plugin – Unix Socket

  • Amazon Key Management encryption plugin

  • Delayed replication for MariaDB versions lower than 10.6

  • Native MariaDB encryption at rest for InnoDB and Aria

    You can enable encryption at rest for a MariaDB DB instance by following the instructions in Encrypting Amazon RDS resources.

  • HandlerSocket

  • JSON table type for MariaDB versions lower than 10.6

  • MariaDB ColumnStore

  • MariaDB Galera Cluster

  • Multisource replication

  • MyRocks storage engine for MariaDB versions lower than 10.6

  • Password validation plugin, simple_password_check, and cracklib_password_check for MariaDB versions lower than 11.4

  • New binary log implementation in InnoDB for MariaDB version 12.3

    RDS for MariaDB doesn't support the binary log implementation in InnoDB that MariaDB 12.3 introduces. The binlog_storage_engine parameter isn't available in the mariadb12.3 parameter group family. For more information about this community feature, see New binlog implementation in MariaDB 12.3 on the MariaDB website.

  • The PATH variable isn't available in the mariadb12.3 parameter group family, and you can't set it as a global variable. You can still set PATH at the session level.

  • Replication user information in the output of SHOW REPLICA HOSTS

    The show_slave_auth_info variable isn't available in the mariadb12.3 parameter group family, so the output of SHOW REPLICA HOSTS doesn't include user and password information.

  • Spider storage engine

  • Sphinx storage engine

  • TokuDB storage engine

  • Storage engine-specific object attributes, as described in Engine-defined new Table/Field/Index attributes in the MariaDB documentation

  • Table and tablespace encryption

  • Hashicorp Key Management plugin

  • Running two upgrades in parallel

To deliver a managed service experience, Amazon RDS doesn't provide shell access to DB instances, and it restricts access to certain system procedures and tables that require advanced privileges. Amazon RDS supports access to databases on a DB instance using any standard SQL client application. Amazon RDS doesn't allow direct host access to a DB instance by using Telnet, Secure Shell (SSH), or Windows Remote Desktop Connection.
