Michael Widenius, the founder of MySQL, has posted his thoughts on the acquisition of Sun by Oracle. I agree with this sentiment:
The biggest threat to MySQL future is not Oracle per se, but that the MySQL talent at Sun will spread like the wind and go to a lot of different companies which will set the MySQL development and support back years.
I would not like to see this happen and I am doing everything I can do to keep this talent pool together (after all, most of them are long time personal friends of mine). I am prepared to hire or find a good home (either at Monty Program Ab or close to it) for all core MySQL personnel.
I think that the best thing that could come out of the merger is the combination of the InnoDB and MySQL teams.
