MySQL is set to announce some exciting new features at its User Conference in Orlando April 14-16 ( The wildly popular free database server is expanding its functionality in attempts to keep up with the competition, PostgreSQL, and Firebird. The two new features are MySQL Cluster and stored procedures.

MySQL Cluster will allow more than one instance of a database to take over if another fails. The software is based on NDB cluster made by Ericsson, who sold the software to MySQL in October. The Software, which can be applied to anything from Operating Systems to individual packages, works by monitoring multiple versions and should any version fail another takes over. The failover rate should be less than a second, according to MySQL. All of the mainstream database sellers, Oracle, Microsoft, and IBM, already support clustering, and this is an attempt by MySQL to become closer to those mainstream database packages.

Stored procedures will allow support for predefined processes. Both PostgreSQL and Firebird provide support for predefined processes. The feature is already supported in the product MaxDB, also produced by MySQL. MaxDB is developed and sold through a partnership with the German software giant SAP.

MySQL User Conference:

The annual users conference for MySQL users and developers on April 14-16 is in Orlando Florida this year. Last years conference was held in San Jose California. This years conference boasts such keynote speakers as:

  • Monty Widenius - Founder / CTO, MySQL AB

  • Brian Behlendorf - Co-founder, Apache Software Foundation, Founder/CTO,

MySQL Licensing Information:

MySQL uses a dual licensing model. Which basically means that you can either license the software under the GNU public license, or under a commercial license. The GNU license is, of course, free. The Commercial license will run you $495/server.

Other MySQL Products:

MaxDB: MaxDB is a rebranded version of SAP DB. Like MySQL MaxDB is open source and does use MySQL's dual licensing model.

MySQL Control Center: A GUI administration client for MySQL

MySQL Administrator: A GUI administration console allows for much more useful administrative features than MySQL Control Center.

Whoa, $800 for a ticket ?! That's just amazing. Another question, actually. Why is MySQL free for a GNU license but $500 for a commercial license? What's the difference? Support?

The commercial license allows you to provide commercial software licenses to your customers. Basically if you are licensing the software you develop using MySQL as open source you can use it for free, but if you plan on keeping the source code yourself then you have to pay the commercial license fee. According to MySQL's website "Commercially licensed customers get commercially supported product with assurances from MySQL." The good thing about this licensing structure is that you don't have to buy the commercial license until you try to distribute software that is non GPL compliant.

No problem. Glad I could be of assistance :).
