MariaDB Enterprise Server Capabilities
High availability
MariaDB Enterprise includes two options to meet enterprise high availability requirements: replication with automatic failover and clustering using synchronous replication.
Automatic failover
MariaDB MaxScale provides MariaDB Enterprise with automatic failover, promoting an up-to-date replica if the primary becomes unreachable or unresponsive, and rerouting application queries to the new primary.
Clustering
MariaDB Enterprise Cluster provides MariaDB Enterprise Server with synchronous clustering for mission-critical applications requiring continuous availability and strong consistency through infrastructure failures.
Zero-interruption failover
While most databases can meet standard high availability requirements with automatic failover and clustering, MariaDB Enterprise Server is the only database with advanced features comparable to Oracle Application Continuity. Together, they hide infrastructure and database failures from applications, resulting in zero-interruption failover.
Disaster recovery
MariaDB Enterprise Server includes a number of tools and features for implementing comprehensive disaster recovery plans, including non-blocking backups and point-in-time restore to online point-in-time rollback. In addition, delayed replicas (e.g., 1 hour, 12 hour and 1 day) can be used as part of an advanced strategy to prevent accidental or malicious data loss/corruption from reaching backups.Â
Enterprise Backup
Perform online, non-blocking backups (full or incremental), create cumulative backups and use them to restore databases to a specific point in time with MariaDB Enterprise Backup.
Flashback
Undo the most recent transactions to recover from malicious or accidental data loss/corruption faster, and without incurring downtime, by using MariaDB Flashback to “rewind the database.”
Delayed replicas
With delayed replication, replicas can be staggered behind the primary in order to prevent data loss/corruption from reaching backups and recover data without needing a restore.
Security
MariaDB Enterprise Server goes above and beyond standard security features such as roles and auditing, with advanced data protection and security layers such as complete, end-to-end encryption, a powerful database firewall to stop intruders and malicious attacks and dynamic data masking/obfuscation to protect customer data and prevent data breaches.
Legacy Database compatibility
MariaDB Enterprise Server is the best place to run SQL applications. It supports ANSI SQL, MySQL, PL SQL, SQL Server and Sybase SQL dialects. This makes it easy for developers to port existing applications with fewer code and schema changes. MariaDB customers have imported hundreds of thousands of lines of legacy database code.
Data types and sequences
MariaDB Enterprise supports standard Oracle Database data types such as VARCHAR2, NUMBER, DATE, RAW, BLOB and CLOB as well as sequences using Oracle Database syntax (e.g., NEXTVAL and CURRVAL).
Oracle Stored Procedures (PL/SQL)
MariaDB is the only enterprise database solution with a 100% open source implementation of Oracle PL/SQL. It supports standard Oracle database packages and procedures including cursors, loops, variables, exceptions and functions such as CAST, LENGTH and SUBSTR.
JSON
MariaDB Enterprise Server supports hybrid relational/JSON data models, allowing developers to extend relational data models with JSON documents and query them with standard SQL for faster development, or to query relational data as JSON documents, while at the same time ensuring DBAs can continue to enforce data integrity and correctness.
Schema flexibility
Add JSON columns to extend existing tables to provide developers with greater flexibility – speed up app development by allowing the data model to evolve on demand rather than requiring schema changes up front.
Standard SQL
Query and index JSON documents with standard SQL using a comprehensive set of JSON functions to read/write JSON documents, fields, array and objects – or return relational data as JSON documents. You can even return a JSON document as a standard SQL row.
