At work we've been contemplating an approach for use in some similar 
situations we want to address.

In broad strokes: keep the updated value in memory, write the value to 
the database "periodically" (for whatever value of "periodically" is 
appropriate for the data).

This should work well when the value changes often and loosing the most 
recent updates to the value isn't catastrophic.
