---------------------------------------------

Oh right, forgot this was in 0.7 too. I'll do that.

> The current implementation of CounterColumn keeps both the partitioned
> counter and the total value of the counter (that is, the sum of the parts of
> the partitioned counter).
> This waste space and this requires the code to keep both representation in
> sync. This ticket propose to remove the total value from the representation
> and to only calculate it when returning the value to the client.
> NOTE: this breaks the on-disk file format (for counters)
