The MySQL crystal ball says …

As the recipient of the 2009 MySQL Community Member of the Year award I received a MySQL crystal ball. While it looks good in my bookcase, unfortunately the best advice I can offer during this time of uncertainty is “watch this space”.

A number of topics where information is still very much unknown and I’m either asked about, or am following includes:

  • MySQL 5.4 Alpha release and schedule for production release
  • The end of MySQL 5.0 Community/Enterprise split
  • The future of Falcon in MySQL 6.0?
