Sylvain Lebresne updated CASSANDRA-1936:
----------------------------------------

    Comment: was deleted

(was: Was that with the test attached to #2005 ? I did not test the distributed 
tests yet,
but I ran a home-backed test (against a local 3 node cluster) doing a bunch of 
adds and then checking the count is what expected and I wasn't able to 
reproduce 
the problem yet (I've tried varying a few parameters: RF, with flush and 
compaction
between insert and read, consistency level).

So if you can share the test, I'd be more than happy to help the digging.)

> 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)
