To use the partition function PARTITION BY RANGE/LIST (TO_DAYS(a_date_field))
will have a very good effect on the optimizer since it will then know that it can apply
range optimisations.

A new feature recently added to 5.1 is the ability to create SQL events. So you could
define an event that on a daily basis adds a new partition and if you want other
regular activities for dropping and reorganizing your partitions that can be done as well.

Check the new devzone article on this:
