MariaDB is a database company that was created as a community-developed ‘fork’ if the MySQL relational database management system and as has always been free to use under the GNU General Public License.
Recent developments though have seen the MariaDB Foundation immediate availability of MariaDB Galera Cluster 5.5.51 Stable (GA) and MariaDB Connector/J 1.5.1 Release Candidate (RC). But… the foundation is also reported to be releasing its MaxScale database proxy software under a proprietary licence.
MaxScale will now be available under what has been called (by MariaDB’s Michael “Monty” Widenius) as a Business Source Licence and usage of the software is free when an application uses the software with a total of less than three database server instances for production purposes.
“The open source model presents challenges to creating a software company that has the needed resources to continually invest in product development and innovation. One reason for this is a lack of understanding of the costs associated with developing and extending software. As one example of what I regard to be unrealistic user expectations,” writes Widenius.
The product is described as an open source, dynamic data routing platform for minimum downtime, security, scalability, and interoperability beyond MariaDB and MySQL.
