Jason Brown commented on CASSANDRA-4180:
----------------------------------------
[~slebresne] I think you are right about that, and disambiguating the two
tickets (at least, in my brain) should make this a little easier.
> 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: Jason Brown
> Labels: compaction
> Fix For: 1.3

>
> 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.
