At least, that’s how it looks. I was intrigued when I saw reports raising the possibility of “high-end” features in MySQL being released under a closed-source license – confirmed (as a possibility) in a roundabout way here. I found it odd because Sun CEO Jonathan Schwartz had told me of Sun’s intention to open source everything.

So what does Schwartz think of the MySQL idea? Not much, according to his statement in this email interview with Tim O’Reilly:

Marten Mickos (SVP, Database Group at Sun, former CEO, MySQL) made some comments saying he was considering making available certain MySQL add-ons to MySQL Enterprise subscribers only – and as I said on stage, leaders at Sun have the autonomy to do what they think is right to maximize their business value – so long as they remember their responsibility to the corporation and all of its communities (from shareholders to developers). Not just their silo.

I think Marten got some fairly direct and immediate feedback saying the idea was a bad one – and we have no plans whatever of “hiding the ball,” of keeping any technology from the community. Everything Sun delivers will be freely available, via a free and open license (either GPL, LGPL or Mozilla/CDDL), to the community.

Everything.

No exception.

Seems clear enough to me.
