Subject [jira] Created: (CASSANDRA-1937) Keep partitioned counters ("contexts") sorted
Date Wed, 05 Jan 2011 15:44:45 GMT
Keep partitioned counters ("contexts") sorted
---------------------------------------------

                 Key: CASSANDRA-1937
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1937
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Sylvain Lebresne
            Assignee: Sylvain Lebresne
             Fix For: 0.8


In the value of CounterColumns, the code keep the subpart unsorted, but sort
them 'on the fly' when needed (in diff() and merge()). It will be more
efficient to keep the parts always sorted (it will also be easier in that it
will remove the need of the ad-hoc in-place quicksort in CounterContext).

NOTE: this breaks the on-disk file format (for counters)
