Subject [jira] [Created] (CASSANDRA-4180) Remove 2-phase compaction
Date Fri, 20 Apr 2012 15:00:43 GMT
Remove 2-phase compaction
-------------------------

                 Key: CASSANDRA-4180
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4180
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Sylvain Lebresne
            Assignee: Sylvain Lebresne
             Fix For: 1.2


LazilyCompactedRow reads all data twice to compact a row which is obviously inefficient. The
main reason we do that is to compute the row header. However, CASSANDRA-2319 have removed
the main part of that row header. What remains is the size in bytes and the number of columns,
but it should be relatively simple to remove those, which would then remove the need for the
two-phase compaction.
