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.) > 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 > > Attachments: > 0001-Put-partitioned-counter-directly-in-column-value.patch, > 1936-ALT-0001-lazily-materialize-value.patch > > Original Estimate: 8h > Remaining Estimate: 8h > > 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) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
