As reported yesterday from CommunityOne:

• MySQL Server is and will always remain fully functional and open source,
• so will the MySQL Connectors, and
• so will the main storage engines we ship.

In addition:

• MySQL 6.0’s pending backup functionality will be open source,
• the MyISAM driver for MySQL Backup will be open source, and
• the encryption and compression backup features will be open source,

where the last item is a change of direction from what we were considering before.

The change comes from MySQL now being part of Sun Microsystems. Our initial plans were made for a company considering an IPO, but made less sense in the context of Sun, a large company with a whole family of complementary open source software and hardware products.

I’d like to shed some light on the big picture, in two different ways — openness, and the business model.

MySQL’s openness manifests itself in three ways:

• MySQL’s code is open.
• MySQL’s APIs are open.
• MySQL’s data formats are open.

These form a foundation around the MySQL Server and its connectors on which we (Sun), our partners, and the community can all freely build upon. And through this openness, we will always provide a means for our users to easily export their data from MySQL.

Then for MySQL’s business model. To financially support MySQL’s free and open source platform, we have a business model which allows both community and commercial add-ons, and we remain committed to it. We believe the model to be useful for both those who spend money to save time, and those who spend time to save money.

As Mårten mentioned yesterday in the CommunityOne panel, expect Sun/MySQL to continue experimenting with the business model, and with what’s offered for the community and what’s offered commercial-only. We won’t always know the right answer from the beginning, but we want MySQL to be the most popular database for both paying and non-paying users.
