Fit partitioned counter directly into CounterColumn.value
----------------------------------------------------------
Key: CASSANDRA-1936
URL: https://issues.apache.org/jira/browse/CASSANDRA-1936
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Fix For: 0.8
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)
