MariaDB Enterprise Server push to strengthen the backup, cluster build and audit functions

Compatible with the MySQL database MariaDB, is now officially enhance security and reliability, the introduction of enterprise-class database product MariaDB Enterprise Server, enhanced backup, cluster build and audit functions, first MariaDB Enterprise Server version 10.4, but is also available older 10.2 and 10.3. Separation out of the MySQL relational database MariaDB, now also provides enterprise version, the official noted that the open source community focus on innovation-release version of the community generally, there are some risks for enterprise production environments may not be safe, especially to perform mission-critical applications, reliability may be tested, so they now offer two versions of the same time, MariaDB Server version can get the latest development of the community, and has a more experimental features, and MariaDB Enterprise Server stressed reliable and stability.

MariaDB Server will first release, after official additional quality assurance procedures to confirm compliance with the standard, before the release of MariaDB Enterprise Server version to users on security, preset disables all extensions unofficial version, and change the default configured to provide stronger security. In addition, because the community edition, backup tools will require a global read lock (Global Read Lock), can only be read-only operations when backing up to avoid at the time of backup data, data changes occur, to be completed until all queries before you can make a read operation, however, this problem may occur on large databases, because when the backup at the same time, the system sudden spikes in traffic, it will be difficult to handle. MariaDB Enterprise Server provides non-blocking backup feature, you can avoid such problems.

On security, the community edition of encryption is not complete, although tables, logs and backup data are encrypted, but multi-master node in the cluster, the data may leak from the transaction buffer (Transaction Buffer), and MariaDB Enterprise Cluster for the transaction buffer encryption, to make up the weakest link. The MariaDB Enterprise also provides a more complete audit functions, including record all configuration changes and many updated and simplified method set. MariaDB Enterprise Server contains many backporting features, so companies do not need regular upgrades to assume risks and uncertainties, but at the same time can use the new features. The official said they would assess the impact of older versions of the demand for new features, as well as other new features to the program code, and then decided to migrate to new features on older versions, such as MariaDB Enterprise backup function, it will backported to provide 10.3 and 10.2.
